 Item 1. Business

 The Allstate Corporation was incorporated under the laws of the State of Delaware on November 5, 1992, to serve as the holding company for Allstate Insurance Company. Its business is conducted principally through Allstate Insurance Company and other subsidiaries (collectively, including The Allstate Corporation, "Allstate").
 Allstate protects people from life's uncertainties with a wide array of protection for autos, homes and personal property. Allstate is primarily engaged in the property and casualty insurance business in the United States and Canada. Additionally, Allstate provides customers other protection solutions such as protection plans that cover consumer electronics, mobile phones and appliances, personal identity protection and accident and health insurance. On November 1, 2023, we announced that we are pursuing the sale of the Health and Benefits business.
 The Allstate Corporation is one of the largest publicly held personal lines insurers in the United States. Allstate's personal property-liability strategy is to increase market share by offering consumers a broad suite of protection solutions and a competitive value proposition across distribution channels. The Allstate brand is widely known through the "You're In Good Hands With Allstate " slogan. Allstate is the second largest personal property and casualty insurer in the United States on the basis of 2022 statutory direct premiums written according to A.M. Best.

 Allstate also has strong market positions in other protection solutions. Allstate Protection Plans provides protection on a wide variety of consumer goods such as cell phones, tablets, computers, furniture and appliances, and has a leading position in distribution through major retailers. Allstate Identity Protection has a leading position in identity protection through workplace benefit programs. In total, Allstate had 194 million policies in force ("PIF") as of December 31, 2023. Allstate Health and Benefits provides accident, health and life insurance through employers, independent agents and direct-to-consumer, and is one of the top voluntary benefits carriers in the market.
 In this Annual Report on Form 10-K, we occasionally refer to statutory financial information. All domestic United States insurance companies are required to prepare statutory-basis financial statements. As a result, industry data is available that enables comparisons between insurance companies, including competitors that are not required to prepare financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP"). We frequently use industry publications containing statutory financial information to assess our competitive position.

 Additional Information and Strategy Updates
 Allstate Protection pricing and risk management strategies Our pricing and underwriting strategies and decisions are designed to generate sustainable profitable growth.
 A proprietary database of underwriting and loss experience enables sophisticated pricing algorithms and methodologies to more accurately price risks while also seeking to attract and retain customers in multiple risk segments.
 • For auto insurance, risk evaluation factors can include, but are not limited to: vehicle make, model and year; driver age and marital status; territory; years licensed; loss history; years insured with prior carrier; prior liability limits; prior lapse in coverage; and insurance scoring utilizing telematics data and other consumer information.
 • For property insurance, risk evaluation factors can include, but are not limited to: the amount of insurance purchased; geographic location of the property; loss history; age, condition and construction characteristics of the property; and insurance scoring utilizing other consumer information.
 A combination of underwriting information, pricing and discounts are also used to achieve a more competitive position and growth. The pricing strategy involves local marketplace pricing and underwriting decisions based on risk evaluation factors to the extent permissible by applicable law and an evaluation of competitors.
 Pricing of property products is intended to generate risk-adjusted returns that are acceptable over a long-term period. Rate increases are pursued to keep pace with loss cost trends, including losses from catastrophic events and those that are weather-related (such as wind, hail, lightning and freeze not meeting our criteria to be declared a catastrophe). We also take into consideration potential customer disruption, the impact on our ability to market our products, regulatory limitations, our competitive position and profitability.
 In any reporting period, loss experience from catastrophic events and weather-related losses may contribute to negative or positive underwriting performance relative to the expectations incorporated into product pricing.
 Property catastrophe exposure is managed with the goal of providing shareholders an acceptable return on the risks assumed in the property business, and reducing variability of earnings, while providing protection to our customers. Catastrophe exposure management includes purchasing reinsurance to provide coverage for known exposure to hurricanes, earthquakes and fires following earthquakes, wildfires and other catastrophes.
 Our current catastrophe reinsurance program supports the Company's risk and return framework which incorporates our robust economic capital model and is informed by catastrophe risk models including

 hurricanes, earthquakes and wildfires and adjusts based on premium and insured value growth. These reinsurance agreements are part of our capital models and our catastrophe risk management framework. As of December 31, 2023, the modeled 1-in-100 probable maximum loss for hurricane, wildfire and earthquake perils is approximately $2.5 billion, net of reinsurance. We continually review our aggregate risk appetite and the cost and availability of reinsurance to optimize the risk and return profile of this exposure.
 The use of different assumptions and updates to industry models and to our risk transfer program could materially change the projected loss. Growth strategies include areas where we believe diversification can be enhanced and an appropriate return can be earned for the risk. As a result, our modeled exposure may increase. In addition, we have exposure to other severe weather events, which impact catastrophe losses.
 We are promoting measures to prevent and mitigate losses that are increasing due to climate change and increased severe weather including making homes and communities more resilient, enforcement of stronger building codes, adoption of sensible land use policies, expanded disaster response capabilities and creation of public risk sharing mechanisms.
 Independent agent strategy The acquisition of National General significantly enhanced our strategic position in the independent agency channel. The transaction increased our total personal property-liability market share by over one percentage point and has enhanced our independent agent-facing technology. It also expanded our distribution footprint, and led us to be a top five personal lines carrier in the independent agency distribution channel.
 National General provides personal and commercial automobile, homeowners, umbrella, recreational vehicle and motorcycle insurance, lender-placed products and other niche insurance products. Auto insurance represents approximately 70% of premium with a significant presence in the non-standard risk auto market. Allstate's capabilities are being leveraged to create additional auto and homeowners insurance products to better serve middle market customers through independent agents.
 As part of the acquisition, Allstate Independent Agency and Encompass organizations are being integrated into National General by:
 • Migrating Encompass policyholders and business operations to National General and retiring the Encompass technology infrastructure
 • Transitioning Encompass and Allstate-branded Independent Agent new business to National General as auto and homeowners insurance products roll out

 The Allstate Corporation 5

 Commercial lines strategy The Allstate brand commercial insurance strategy is being advanced through an equity investment and commercial partnership with NEXT Insurance, a high-growth, digital platform for small business insurance. This partnership will expand the availability of our commercial lines offerings via the NEXT product portfolio, which complements the Allstate commercial auto product suite, across a wider distribution network.
 Profit improvement actions continue for our Allstate brand traditional legacy commercial lines insurance products, emphasizing pricing, claims, operational improvements and non-renewal of policies where we are unable to meet our profit target. In 2023, Allstate brand began exiting traditional commercial insurance in five states, which is expected to be completed by mid-year 2025. These five states combined made up 36% of 2022 Allstate brand

 commercial net written premium. Additionally, as of the fourth quarter of 2022, coverage is no longer offered to transportation network companies unless the contracts utilize telematics-based pricing. National General commercial auto product lines are expected to continue organic growth as well as expand to new geographies.
 Answer Financial strategy Answer Financial is an insurance agency that sells other insurance companies' products directly to customers. Our strategy as a technology-enabled insurance agency is to provide comparison shopping and related services for businesses, offering customers choice, convenience and ease of use.

 Exclusive agent compensation structure The compensation structure for Allstate exclusive agents rewards them for delivering high value to customers and achieving certain business outcomes such as profitable growth and household penetration. Allstate

 • Agents receive a monthly base commission payment as a percentage of their total eligible written premium.

 6 www.allstate.com

 • Bonus compensation is based on a percentage of premiums and can be earned by agents who are meeting certain sales goals and selling additional policies to meet customer needs profitably.

 of personal insurance premiums primarily related to property business in hurricane exposed areas, and approximately $259 million of commercial insurance premiums.
 Additionally, we offer a homeowners product through our excess and surplus lines carrier, North Light Specialty Insurance Company, in certain areas with higher risk of catastrophes or where customers do not meet the Allstate brand standard underwriting profile.
 Allstate agents and exclusive financial specialists receive commissions for non-proprietary life and retirement sales and are eligible for a quarterly bonus based on the volume of non-proprietary sales.
 Independent agent remuneration for National General comprises a base commission and a bonus that can be earned by agents who achieve sales goals and a target loss ratio.

 Strategy
 Allstate Health and Benefits segment accounted for 4.2% of Allstate's 2023 consolidated total revenue and 2.1% of Allstate's December 31, 2023 PIF. The Allstate Health and Benefits segment provides consumers with financial protection against the risk of accidents, illness and mortality. We are among the industry leaders in the growing and highly competitive voluntary benefits market, offering a broad range of accident, health and life products through workplace enrollment. Our life insurance portfolio includes individual and group permanent life solutions.

Recent entrants, including large group medical, life and disability insurance carriers, are leveraging core benefit capabilities by bundling and discounting to capture voluntary market share.

 Other Business Segments
 Run-off Property-Liability Segment
 The Run-off Property-Liability segment includes results from property and casualty insurance coverage that primarily relates to policies written during the 1960s through the mid-1980s.
 Strategy Management of this segment has been assigned to a designated group of professionals with expertise in claims handling, policy coverage interpretation, exposure identification, litigation and reinsurance collection. We may pursue settlement agreements including policy buybacks on direct excess commercial business when appropriate to improve the certainty of the liabilities. Settlement agreements are negotiated contracts between Allstate and third parties that generally set forth the rights and obligations of the parties, including terms of payment for claims. At the end of 2023, 68% of the gross case reserves, excluding incurred but not reported, on the run-off direct excess commercial business were attributable to settlement agreements. This group also manages other direct commercial and assumed reinsurance business in runoff and engages in reinsurance ceded and assumed commutations as required or when considered economically advantageous.
 Changes in the reserves established for asbestos, environmental and other run-off lines losses have occurred and may continue. Reserve changes can be caused by new information relating to new and additional claims, new exposures or the impact of resolving unsettled claims based on unanticipated events such as arbitrations, litigation, legislative, judicial or regulatory actions. Environmental losses may also increase as the result of additional funding for environmental site clean-up.
 Challenges related to the concentration of insurance and reinsurance claims from companies who specialize in this business continue to be addressed.
 Corporate and Other Segment
 Our Corporate and Other segment is comprised of debt service, holding company activities and certain non-insurance operations, including expenses associated with strategic initiatives, such as our Avail peer-to-peer car-sharing initiative.

 The Allstate Corporation 11

 Regulation
 Allstate is subject to extensive regulation, primarily at the state level. The method, extent and substance of such regulation vary by state but generally have their source in statutes that establish standards and requirements for conducting the business of insurance and that also delegate regulatory authority to a state agency. These rules have a substantial effect on our business and relate to a wide variety of matters, including insurer solvency and statutory surplus sufficiency, reserve adequacy, insurance company licensing and examination, agent and adjuster licensing, agent and broker compensation, policy forms, rate setting, the nature and amount of investments, claims practices, participation in shared markets and guaranty funds, transactions with affiliates, the payment of dividends, underwriting standards, statutory accounting methods, trade practices, privacy regulation and data security, corporate governance and risk management. In addition, state legislators and insurance regulators continue to examine the appropriate nature and scope of state insurance regulation. For a discussion of statutory financial information, see Note 17 of the consolidated financial statements.
 For a discussion of regulatory contingencies, see Note 15 of the consolidated financial statements. Note 15 and Note 17 are incorporated in this Part I, Item 1 by reference.
 The Dodd-Frank Wall Street Reform and Consumer Protection Act ("Dodd-Frank") created the Federal Insurance Office ("FIO") within the U.S. Department of the Treasury ("Treasury"). The FIO monitors the insurance industry, provides advice to the Financial Stability Oversight Council ("FSOC"), represents the U.S. on international insurance matters, and studies the current regulatory system.
 Additional regulations or new requirements may emerge from the activities of various regulatory entities, including the Federal Reserve Board, FIO, FSOC, the National Association of Insurance Commissioners ("NAIC"), and the International Association of Insurance Supervisors, that are evaluating solvency and capital standards for insurance company groups. In addition, the NAIC has adopted amendments to its model holding company law that have been adopted by some jurisdictions. The outcome of these actions is uncertain; however, these actions may impact the business models and profitability of insurance holding companies.
 We cannot predict whether any specific state or federal measures will be adopted to change the nature or scope of the regulation of insurance or what effect any such measures would have on Allstate. We are working for changes in the regulatory environment to make insurance more available and affordable for customers, encourage market innovation, improve driving safety, strengthen cybersecurity and promote better catastrophe preparedness and loss mitigation.

 Limitations on Dividends by Insurance Subsidiaries As a holding company with most business operations conducted by subsidiaries, The Allstate Corporation relies on dividends from Allstate Insurance Company as one of the principal sources of cash to pay dividends and to meet its obligations, including the payment of principal and interest on debt or to fund non-insurance-related businesses. Allstate Insurance Company is regulated as an insurance company in Illinois, and its ability to pay dividends is restricted by Illinois law. The laws of the other jurisdictions that generally govern our other insurance subsidiaries contain similar limitations on the payment of dividends. However, such laws in some jurisdictions may be more restrictive.
 For additional information regarding limitations, see Part II, Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operations of this report.
 In addition, the NAIC adopted a group capital calculation covering all entities of the insurance company group for use in solvency monitoring activities by regulators. Any increase in the amount of capital or reserves our insurance subsidiaries are required to hold could reduce the amount of future dividends such subsidiaries are able to distribute to the holding company. Any reduction in the risk-based capital ("RBC") ratios of our insurance subsidiaries could also adversely affect their financial strength ratings as determined by statistical rating agencies. We have not experienced, and we do not expect to experience, any impact from the group capital calculation on our current dividend plans.
 Insurance Holding Company Regulation – Change of Control The Allstate Corporation is a holding company and its insurance subsidiaries are subject to regulation in the jurisdictions in which they write business. In the U.S., these subsidiaries are organized under the insurance codes of Alabama, California, Florida, Illinois, Indiana, Massachusetts, Michigan, Mississippi, Missouri, New Jersey, New York, North Carolina, Ohio, South Carolina and Texas. Additionally, some of these subsidiaries are considered commercially domiciled in California, Florida, and Texas.
 Generally, the insurance codes in these states provide that the acquisition or change of "control" of a domestic or commercially domiciled insurer or of any person that controls such an insurer cannot be consummated without the prior approval of the relevant insurance regulator. In general, a presumption of "control" arises from the ownership, control, possession with the power to vote, or possession of proxies with respect to ten percent or more of the voting securities of an insurer or of a person who controls an insurer. In addition, certain state insurance laws require pre-acquisition notification to state agencies of a change in control with respect to a non-domestic insurance company licensed to do business in that state. While such pre-acquisition notification

 12 www.allstate.com

 statutes do not authorize the state agency to disapprove the change of control, such statutes do authorize certain remedies, including the issuance of a cease-and-desist order with respect to the non-domestic insurer if certain conditions exist, such as undue market concentration.
 Thus, any transaction involving the acquisition of ten percent or more of The Allstate Corporation's common stock would generally require prior approval by the state insurance departments in Alabama (where the threshold is five percent or more of The Allstate Corporation's common stock), California, Florida, Illinois, Indiana, Massachusetts, Michigan, Mississippi, Missouri, New Jersey, New York, North Carolina, Ohio, South Carolina and Texas. Moreover, notification would be required in those other states that have adopted pre-acquisition notification provisions and where the insurance subsidiaries are admitted to transact business. Such approval requirements may deter, delay or prevent certain transactions affecting the ownership of The Allstate Corporation's common stock.
 Rate Regulation Nearly all states have insurance laws requiring personal property and casualty insurers to file rating plans, policy or coverage forms, and other information with the state's regulatory authority. In many cases, such rating plans, policy forms, or both must be approved prior to use.
 The speed with which an insurer can change rates in response to competition or increasing costs depends on the state rating laws, which include the following categories:
 • Prior approval — Regulators must approve a rate before the insurer may use it (21 states)
 • File-and-use — Insurers do not have to wait for the regulator's approval to use a rate, but the rate must be filed with the regulatory authority prior to being used (20 states)
 • Use-and-file — Requires an insurer to file rates within a certain period of time after the insurer begins using them (9 states)
 • No filing or approval — One state, with an immaterial amount of written premiums, does not require a filing to be submitted
 Under these rating laws, the regulator has the authority to disapprove a rate filing.

 An insurer's ability to adjust its rates in response to competition or to changing costs is dependent on an insurer's ability to demonstrate to the regulator that its rates or proposed rating plan meets the requirements of the rating laws. In those states that significantly restrict an insurer's discretion in selecting the business that it wants to underwrite, an insurer can manage its risk of loss by charging a rate that reflects the cost and expense of providing the insurance. In those states that significantly restrict an insurer's ability to charge a rate that reflects the cost and expense of providing the insurance, the insurer may be able to manage its risk of loss by being more selective in the type of business it underwrites. When a state significantly restricts both underwriting and pricing, it becomes more difficult for an insurer to maintain its targeted level of profitability.
 From time to time, the personal lines insurance industry comes under pressure from state regulators, legislators, and special-interest groups to reduce, freeze, or set rates at levels that do not correspond with our analysis of underlying costs, catastrophe loss exposure, and expenses. We expect this kind of pressure to persist. Allstate and other insurers are using increasingly sophisticated pricing models and rating plans that are reviewed by regulators and special-interest groups. States may limit the ability of insurers to include variables in their rating plans even though they are indicative of risk. State regulators may interpret existing law or rely on future legislation or regulations to impose new restrictions that adversely affect profitability or growth. We cannot predict the impact on our business of possible future legislative and regulatory measures regarding insurance rates.
 Involuntary Markets As a condition of maintaining our licenses to write personal property and casualty insurance in various states, we are required to participate in assigned risk plans, reinsurance facilities, and joint underwriting associations that provide various types of insurance coverage to individuals or entities that otherwise are unable to purchase such coverage from private insurers. Underwriting results related to these arrangements, which tend to be adverse, have been immaterial to our results of operations.
 For a discussion of these items see Note 15 of the consolidated financial statements. Note 15 is incorporated in this Part I, Item 1 by reference.
 Indemnification Programs We are a participant in state-based industry pools, facilities or associations, mandating participation by insurers offering certain coverage in their state, including the Michigan Catastrophic Claims Association ("MCCA"), the New Jersey Property-Liability Insurance Guaranty Association, the North Carolina Reinsurance Facility and the Florida Hurricane Catastrophe Fund. We also participate in the Federal Government National Flood Insurance Program.

 Recent regulatory changes have occurred related to the MCCA.
 • On July 2, 2021, Public Acts 21 and 22, which passed in 2019, became effective, setting fee schedules for personal injury protection claims. Such fee schedules were set at 200% of Medicare rates in 2021, declining to 195% in 2022 and 190% in 2023, for any providers other than certain unique categories of providers and applying to treatment on existing and new claims.
 • Other legislative proposals to change the MCCA operation in the future and to adjust Public Acts 21 and 22 are put forth periodically, as well as a recent Michigan Supreme Court decision that found that the reimbursement rates described above applied only to motor vehicle accidents occurring in 2019 or later.
 For a discussion of these items see Note 11 of the consolidated financial statements. Note 11 is incorporated in this Part I, Item 1 by reference.
 Guaranty Funds Under state insurance guaranty fund laws, insurers doing business in a state can be assessed, up to prescribed limits, in order to cover certain obligations of insolvent insurance companies. We do not anticipate any material adverse financial impact on Allstate from these assessments.
 Investment Regulation Our insurance subsidiaries are subject to state regulation that specifies the types of investments that can be made and concentration limits of invested assets. Failure to comply with these rules leads to the treatment of non-conforming investments as non-admitted assets for purposes of measuring statutory surplus. Further, in some instances, these rules require divestiture of non-conforming investments.
 Exiting Geographic Markets; Canceling and Non-Renewing Policies Most states regulate an insurer's ability to exit a market. For example, states may limit, to varying degrees, an insurer's ability to cancel and non-renew policies. Some states restrict or prohibit an insurer from withdrawing one or more types of insurance business from the state, except pursuant to a plan that is approved by the state insurance department. Regulations that limit cancellation and non-renewal and that subject withdrawal plans to prior approval requirements may restrict an insurer's ability to exit unprofitable markets.
 Broker-Dealer and Investment Advisers The Allstate entities that operate as a broker-dealer and registered investment advisers are subject to regulation and supervision by the Securities and Exchange Commission ("SEC"), Financial Institution Regulatory Authority and/or, in some cases, state securities administrators. The SEC has proposed rules and amendments related to cybersecurity risk management and cybersecurity-related disclosure for broker-dealers, registered investment advisers, registered investment companies, and business development companies. Certain state and federal regulators are considering or have implemented best

 interest or fiduciary standards. Such standards could impact products provided by Allstate agents and Allstate's broker-dealer, their sales processes, sales volume, and producer compensation arrangements.
 Inflation Reduction Act of 2022 The Inflation Reduction Act of 2022, which contains several tax-related provisions, was signed into law in August 2022. The law creates a 15% corporate alternative minimum tax ("CAMT") on certain large corporations and an excise tax of 1% on stock repurchases by publicly traded U.S. corporations, both effective after December 31, 2022. The excise tax on common stock repurchases is classified as an additional cost of the stock acquired included in treasury stock in shareholders' equity. The Company has determined that it is considered an "applicable corporation" under the rules of CAMT.
 15% Global Minimum Tax The Organization for Economic Cooperation and Development ("OECD") secured agreement from nearly 140 countries to address how corporate profits are taxed for multinational enterprises ("MNEs"). OECD has released Pillar Two Model Rules, a 15% minimum effective tax rate (also known as the Global Anti-Base Erosion "GloBE" Rules), designed to ensure that large MNEs pay a minimum level of tax on the income arising in each jurisdiction where they operate and mandates sharing of certain company information with taxing authorities on a local and global basis.
 Certain jurisdictions have enacted, and others have proposed, legislation to implement certain provisions of Pillar Two for fiscal years beginning on or after December 31, 2023. We are continuing to monitor the implications resulting from the potential enactment of Pillar Two rules in the jurisdictions where we operate.
 Climate disclosures In March 2022, the SEC released its climate-related proposed regulation, requiring registrants to provide certain climate-related information in their registration statements and annual reports. The proposed rule would require information about a registrant's climate-related risks that are reasonably likely to have a material impact on its business, results of operations, or financial condition. The required information about climate-related risks would also include disclosure of a registrant's greenhouse gas emissions, which have become a commonly used metric to assess a registrant's exposure to such risks. In addition, under the proposed rule, certain climate-related financial metrics would be required in a registrant's audited financial statements. The Company is evaluating the anticipated impacts of the proposed guidance to its disclosures.
 In October 2023, California enacted several climate disclosure bills. One of these is the Climate Corporate Data Accountability Act (Senate Bill 253), which requires disclosure and assurance over greenhouse gas emissions using a phased reporting approach. The law requires the California Air Resources Board to develop and adopt implementing regulations no later than January 1, 2025. Allstate has publicly reported its greenhouse gas inventory since 2010. We will continue

 14 www.allstate.com

 evaluating the anticipated impacts and scope of the new laws on our reporting and disclosures.
 Dodd-Frank: Covered Agreement On September 22, 2017, the U.S. and European Union signed a Covered Agreement, a bilateral agreement that "relates to the recognition of prudential measures with respect to the business of insurance or reinsurance that achieves a level of protection for insurance or reinsurance consumers that is substantially equivalent to the level of protection achieved under State insurance or reinsurance regulation."
 The U.S. had five years from the date of signing to amend its credit for reinsurance laws and regulations to conform with the requirements of the Covered Agreement or face federal preemption determinations by the FIO. To address the requirements of the Covered Agreement, the NAIC formally adopted revisions to its existing credit for reinsurance model law and model regulation, with the expectation that states would adopt and implement the modified model law and regulation by September 2022. A sufficient number of states have adopted the model law and/or regulation to avoid federal preemption.
 Division Statute On November 27, 2018, the Illinois General Assembly passed legislation authorizing a statute that makes available a process by which a domestic insurance company may divide into two or more domestic insurance companies. The statute, which became effective January 1, 2019, can be used to divide continuing blocks of insurance business from insurance business no longer marketed, or otherwise discontinued into separate companies with separate capital. The statute can also be used for sale to a third party or to manage risks associated with indemnification programs. Before a plan of division can be effected it must be approved according to the organizational documents of the dividing insurer and submitted for approval by the Illinois Department of Insurance. In 2021, Allstate Insurance Company and certain affiliate insurance companies utilized the division statute to form three Illinois domiciled insurance companies that retained assets and liabilities for certain Michigan automobile insurance policies with catastrophic personal injury claims that are ceded to the MCCA.
 Privacy Regulation and Data Security Federal law and the laws of many states require financial institutions to protect the security and confidentiality of consumer information and to notify consumers about their policies and practices relating to collection, use, disclosure, and protection of consumer information. Federal law and the laws of many states also regulate disclosures and disposal of consumer information. Congress, state legislatures, and regulatory authorities are currently considering additional regulation relating to privacy of personal information.

 For example, the California Consumer Privacy Act, as amended by the California Privacy Rights Act, which took effect in January 2023, as well as similar laws in Virginia, Connecticut, and approximately nine other states (with various effective dates), impose significant compliance requirements for certain businesses in those states. Among other things, these privacy laws provide consumers with privacy rights such as the right to request access to or deletion of their personal information. The California Privacy Rights Act established a new privacy regulatory agency. In November 2023, the New York State Department of Financial Services amended its cybersecurity regulation, including both new and heightened requirements. The NAIC created an Insurance Data Security Model Law, which several states have adopted in some form, establishing standards for data security, including the investigation of and notification to insurance commissioners of cybersecurity events. Additional states are also likely to adopt similarly themed cybersecurity requirements in the future. We cannot predict the impact on our business of possible future legislative or regulatory measures regarding privacy or cybersecurity.
 Asbestos Congress has repeatedly considered legislation to address asbestos claims and litigation in the past. We cannot predict the impact on our business of possible future legislative measures regarding asbestos.
 Environmental Environmental pollution and clean-up of polluted waste sites is the subject of federal and state regulation. The Comprehensive Environmental Response Compensation and Liability Act of 1980 (the "Superfund") and comparable state statutes (the "mini-Superfunds") govern the clean-up and restoration of waste sites by Potentially Responsible Parties ("PRPs"). The Superfund and the mini-Superfunds (collectively, the "Environmental Clean-up Laws" or "ECLs") establish a mechanism to assign liability to PRPs or to fund the clean-up of waste sites if PRPs fail to do so. The extent of liability to be allocated to a PRP depends on a variety of factors. The insurance industry is involved in extensive litigation regarding coverage issues arising out of the clean-up of waste sites by insured PRPs and the insured parties' alleged liability to third parties responsible for the clean-up. The insurance industry, including Allstate, has disputed and is disputing many such claims. Key coverage issues include whether the Superfund response, investigation, and clean-up costs are considered damages under the policies; whether coverage has been triggered; whether any pollution exclusion applies; whether there has been proper notice of claims; whether administrative liability triggers the duty to defend; whether there is an appropriate allocation of liability among potentially responsible insurers; and whether the liability in question falls within the definition of an "occurrence." Identical coverage issues exist for clean-up and waste sites not covered under the Superfund. To date, courts have been inconsistent in their rulings on these issues.

 The Allstate Corporation 15

 Allstate's exposure to liability with regard to its insureds that have been, or may be, named as PRPs is uncertain. While comprehensive Superfund reform proposals have been introduced in Congress, only modest reform measures have been enacted. In May 2017, the Environmental Protection Agency created a Superfund Task Force that issued proposed reforms in its 2019 final report. These recommendations address expediting clean-up and remediation processes, reducing the financial burden of the clean-up process, encouraging private investment, promoting redevelopment and community revitalization, and building and strengthening partnerships. We cannot predict which, if any, of these reforms will be enacted or, if enacted, what their impact may be.

 Developments in the insurance and reinsurance industries have fostered a movement to segregate asbestos, environmental and other run-off lines exposures into separate legal entities with dedicated capital. Regulatory bodies in certain cases have supported these actions. We are unable to determine the impact, if any, that these developments will have on the collectability of reinsurance recoverables in the future.

 Human Capital
 Allstate's success is highly dependent on human capital. The wellbeing of our employees is a key priority, and Allstate strives to promote a dynamic and welcoming workplace that promotes inclusive diversity and equity, fosters collaboration, and encourages employees to be fully engaged in their work every day. As of December 31, 2023, Allstate had approximately 53,000 full-time employees and 400 part-time employees.
 Allstate's human capital management focuses on the following priorities:
 Talent Recruitment and Management We seek to provide employees with rewarding work, professional growth and educational opportunities.
 • Our flexible work and equal opportunity policies support talent attraction and retention. This has enabled us to recruit a more geographically dispersed and diverse talent pool, as well as to reduce our facilities footprint.
 • Performance review and development takes place throughout the year, with a renewed focus on driving performance through ongoing feedback and coaching. Allstate invests in training and re-skilling opportunities, with most of our learning experiences offered virtually to support our remote and global workforce.
 • In 2023, Allstate:
 –Introduced a new education benefit provider, Guild. Guild expands support and access to over 80 tuition-free professional degrees, certificates and bootcamps to all U.S. based employees at more than 25 schools.
 –Completed more than 450 thousand hours of voluntary continued learning from external and internal providers
 –Delivered over 400 virtually facilitated workshops focused on technical upskilling, well-being, on-boarding, Inclusive Diversity and Equity ("IDE"), and leadership development, totaling close to 800 hours of learning for over 10,000 participants
 –Invested over $2.4 million towards the cost of the degrees of almost 700 U.S. employees.
 –Filled over 28% of open U.S. positions with internal applicants.
 Inclusive Diversity and Equity We strive for a workforce where the breadth of our diversity makes us a better company. IDE is one of Allstate's core values of Our Shared Purpose.

 U.S. workforce diversity as of December 31, 2023

 • Talent acquisition, development, retention, and mobility practices support employees in achieving their career aspirations. We work to create a diverse talent pipeline.
 • As part of our commitment to fair and equitable compensation practices, we complete pay equity analyses. Annually, we identify potential pay gaps across substantially similar employee groups as well as identify policies, practices or systematic issues that may contribute to pay gaps. The external analyses found that Allstate's results compared well to benchmarks for companies of similar size and scope.
 • Allstate supports and funds Employee Impact Groups ("EIGs") and Business Impact Groups ("BIGs") to help advance IDE and create opportunities for employees to work together to create business solutions.
 –EIGs are voluntary employee-led communities that enhance the employee experience through engagement, development and collaboration. They bring value to participants and impact Allstate through cultural education and awareness, market and community outreach, professional development, recruiting, retention, and customer engagement. EIGs are required to interact with at least two other EIGs annually.
 –BIGs, voluntary employee-led groups that focus on creating business impact and serve as an incubator for innovation, collaboration and professional development.
 –Officers from across the enterprise leverage their time, networks and resources to support the EIGs and BIGs, and positively impact employee engagement and feelings of belonging at Allstate.
 • Allstate continues to make significant progress on our IDE strategy while aligning it to Allstate's global talent strategy. In 2023, we:
 –Improved representation by attracting more qualified candidates with remote work options. We've seen an increase in applicants since we announced our permanent flexible work environment, including an increase in diverse candidates.
 –Since the Allstate IDE A.C.T. (Accountability, Clarity, Transparency) Framework rolled out in 2022, every business unit now has either an IDE Inclusion Council or an IDE Business Lead that partners with Human Resources on their business area-based action plans to achieve our corporate IDE strategy.
 –Incorporated IDE behavior questions into structured interviews for executive candidates.

 The Allstate Corporation 17

 Employee Well-being and Safety We believe in a culture of well-being and take our responsibility to care for employees' well-being seriously, devoting resources to employee health and safety.
 • Allstate created a workplace well-being strategy based on employee feedback, including providing greater flexibility in how, when, and where work is done.
 • Allstate hosts enterprise-wide talks with subject matter experts sharing personal stories and fact-based best practices to provide tangible ways employees can support their individual journey. EIGs promote sessions that are relevant to their networks to build a sense of community.
 • Communications and voluntary courses facilitated by internal performance coaches on well-being themes of mind, body, wallet and community are shared so employees can engage in content that matters most to them.
 • Well-being assessments are offered to understand employee needs and wants to support their well-being. Completing the assessment lowers the cost of benefits to employees and allows Allstate to provide holistic programs based on personalized interests.
 • Our Wellbeing Champion community connects their teams and leaders with Allstate's health and wellness resources and promotes opportunities to engage in programs, including virtual yoga and meditation classes offered four times a week.
 Organizational Culture Allstate defines culture as a self-sustaining system of shared values, priorities and principles that shape beliefs and drive behaviors and decision-making within an organization. Allstate encourages employees to proactively manage their career so it is integrated into their personal purpose. This includes investing in and holding management accountable for employee development and maintaining a culture aligned with Our Shared Purpose at all levels.
 • We have a strong culture built on shared purpose, values, standards, and behaviors and are transforming to become the lowest cost protection provider with an affordable, simple, connected experience.
 • We focus on Integrity & Ethics, Belonging, Meaningful Work, Performance Standards, Career Development, Employee Listening, Distributed Work and Well-being to make Allstate a place talent loves.

 • Allstate continues to commit to leadership development, now with the introduction of the Leading at Allstate program. This initiative, focusing on leading change, performance and growth, leadership styles, and leading distributed teams, saw a successful fourth quarter early adopter pilot. Notably, over 250 leaders completed live sessions, with feedback indicating a 95% willingness to recommend the learning and 97% employee satisfaction with the content.
 • Allstate, driven by a leadership-instilled commitment to Inclusive Diversity and Equity, launched a tool that helps learners discover their work-style preference, integrating it into the Degreed learning system. This initiative breaks barriers and fosters inclusion through IDE resources, accessible via both traditional classroom training and the Degreed Learning Hub. Over 3,300 individuals accessed the work-style preferences tool.

 The Allstate Corporation 21

 Item 1A. Risk Factors
 Summary Risks are grouped into three categories: (1) insurance and financial services, (2) business, strategy and operations and (3) macro, regulatory and risk environment. Many risks may affect more than one category and are included where the impact is most significant. If some of these risk factors occur, they may cause the emergence of or exacerbate the impact of other risk factors, which could materially increase the severity of the impact of these risks on our business, results of operations, financial condition or liquidity. The table below includes examples of risks from each category.

 The Allstate Corporation Board of Directors ("Allstate Board") has overall responsibility for oversight of Management's design and implementation of our Enterprise Risk and Return Management ("ERRM") framework that manages the business on an integrated basis following our risk and return principles. The Risk and Return Committee of the Allstate Board oversees effectiveness of the ERRM program, governance structure and risk-related decision-making, while focusing on the Company's overall risk profile.
 See Management's Discussion and Analysis ("MD&A"), Enterprise Risk and Return Management for further details.
 Consider these cautionary statements carefully together with other factors discussed elsewhere in this document, in filings with the Securities and Exchange Commission ("SEC") or in materials incorporated therein by reference.

 Insurance and financial services

 Property and casualty actual claim costs may exceed current reserves established for claims due to changes in the inflationary, regulatory and litigation environment
 Estimating claim reserves is an inherently uncertain and complex process. We continually refine our best estimates of losses after considering known facts and interpretations of the circumstances.
 Our reserving methodology may be impacted by the following:
 • Models that rely on the assumption that past loss development patterns will persist into the future
 • Internal factors including experience with similar cases, actual claims paid, historical trends involving claim payment and case reserving patterns, pending levels of unpaid claims, loss management programs, product mix, contractual terms and changes in claim reporting and settlement practices
 • External factors such as inflation, court decisions, changes in law or litigation imposing unintended

 coverage, regulatory requirements, changes in driving patterns, delays in reporting of claims and economic conditions, supply chain disruptions and labor shortages
 • The ultimate cost of losses, or our current estimates, have and may continue to vary materially from recorded reserves and such variance may adversely affect our results of operations and financial condition as the reserves and amounts due from reinsurers are reestimated
 See MD&A, Application of Critical Accounting Estimates for further details.
 Unexpected increases in the frequency or severity of property and casualty claims may adversely affect our results of operations and financial condition
 A significant increase in claim frequency could adversely affect our results of operations and financial condition. Changes in mix of business, miles driven, weather, driving behaviors or other factors can lead to changes in claim frequency. We may experience volatility in claim frequency, and short-term trends may not be predictive of future losses over the longer term.
 Increases in claim severity can arise from numerous causes that are inherently difficult to

 22 www.allstate.com

 predict. The following factors have and may continue to impact claim severity for auto bodily injury, auto physical damage (including collision and property damage) and homeowners coverages:
 • Bodily injury — more severe accidents, an increase in claims with attorney representation, higher medical consumption, and inflation
 • Vehicle physical damage — inflation, supply chain disruptions and labor shortages impacting used vehicle and parts prices, labor rates, length of claim resolution, delays in the receipt of third-party carrier claims, and a higher mix of total losses
 • Homeowners — inflation in the construction industry, building materials and home furnishings, changes in the mix of loss type, and other economic and environmental factors, including short-term supply imbalances for services and supplies in areas affected by catastrophes
 Catastrophes and severe weather events may subject us to significant losses
 Catastrophic events could adversely affect operating results and cause them to vary significantly from one period to the next. Climate change could contribute to increased variability of catastrophe losses and underwriting results. Also, our liquidity could be constrained by a catastrophe, or multiple catastrophes, which could result in extraordinary losses, sales of investments or a downgrade of our debt or financial strength ratings.
 Catastrophic losses are caused by wind and hail, wildfires, tornadoes, hurricanes, tropical storms, earthquakes, severe freeze events, volcanic eruptions, terrorism, cyber-attacks, civil unrest, industrial accidents and other such events.
 Our personal property insurance business may incur catastrophe losses greater than:
 • Those experienced in prior years
 • The average expected level used in pricing
 • Current reinsurance coverage limits
 • Loss estimates from hurricane and earthquake models at various levels of probability
 Property and casualty businesses are subject to claims arising from severe weather events such as winter storms, rain, hail and high winds. The incidence and severity of weather conditions resulting in claims are extremely volatile.
 The total number of policyholders affected by the event, the severity of the event and the coverage provided contribute to catastrophe and severe weather losses. Increases in the insured values of covered property, geographic concentration and the number of policyholders exposed to certain events could increase the severity of claims from catastrophic and severe weather events.
 Limitations in analytical models used to assess and predict the exposure to catastrophe losses may adversely affect our results of operations and financial condition

 We use internally developed and third-party vendor models along with our own historical data to assess exposure to catastrophe losses. The models assume various conditions and probability scenarios and may not accurately predict future losses or measure losses currently incurred.
 Price competition and changes in regulation and underwriting standards in property and casualty businesses may adversely affect our results of operations and financial condition
 The personal property-liability market is highly competitive with carriers competing through underwriting, advertising, price, customer service, innovation and distribution. Changes in regulatory standards regarding underwriting and rates could also affect the ability to predict future losses and could impact profitability. Competitors can alter underwriting standards, lower prices and increase advertising, which could result in lower growth or profitability for Allstate. A decline in the growth or profitability of the property and casualty businesses could have a material effect on our results of operations and financial condition.
 Our investment portfolios are subject to market risk and declines in credit quality which may adversely affect or create volatility in our investment income and cause realized and unrealized losses
 We continually evaluate investment management strategies since we are subject to risk of loss due to adverse changes in interest rates, credit spreads, equity prices, real estate values, currency exchange rates and liquidity. Adverse changes have and may continue to occur due to changes in monetary and fiscal policy, inflation, geopolitical events and the economic climate, liquidity of a market or market segment, investor return expectations or risk tolerance, insolvency or financial distress of key market makers or participants, instability of the banking sector, or changes in market perceptions of credit worthiness.
 Inflation has been and continues to remain elevated, which has led to volatility of interest rates. The U.S. Federal Reserve and other central banks have responded to inflationary pressure, generally through more restrictive monetary policy, including increasing target interest rates. These actions could create significant economic uncertainty. Market volatility resulting from these factors has and may continue to impact our investment valuations and returns and impact our results of operations and financial condition.

 The Allstate Corporation 23

 Our investments are subject to risks associated with economic and capital market conditions and factors that may be unique to our portfolio, including:
 • General weakening of the economy, which is typically reflected through higher credit spreads and lower equity and real estate valuations
 • Declines in credit quality
 • Declines in interest rates, credit spreads or sustained low interest rates could lead to declines in portfolio yields and investment income
 • Increases in market interest rates, credit spreads or a decrease in liquidity could have an adverse effect on the value of our fixed income securities that form a substantial majority of our investment portfolios
 • Supply chain disruptions, labor shortages, macro trends impacting real estate supply and demand and other factors may have an adverse impact on investment valuations and returns
 • Weak performance of general and joint venture partners and underlying investments unrelated to general market or economic conditions could lead to declines in investment income and cause realized losses in our limited partnership interests
 • Concentration in any particular issuer, industry, collateral type, group of related industries, geographic sector or risk type
 The amount and timing of net investment income, capital contributions and distributions from our performance-based investments, which primarily include limited partnership interests that are recorded on a lag, can fluctuate significantly due to the underlying investments' performance or changes in market or economic conditions. Additionally, these investments are less liquid than similar, publicly-traded investments and a decline in market liquidity could impact our ability to sell them at their current carrying values.
 Declining equity markets or increases in interest rates or credit spreads could cause the value of the investments in our pension plans to decrease. Declines in interest rates could cause the funding ratio to decline and the value of the obligations for our pension and postretirement plans to increase. These factors could decrease the funded status of our pension and postretirement plans, increasing the likelihood or magnitude of future benefit expense and contributions.
 Determination of the fair value and amount of credit losses for investments includes subjective judgments and could materially impact our results of operations and financial condition
 The valuation of the portfolio is subjective, and the value of assets may differ from the actual amount received upon the sale of an asset. The degree of judgment required in determining fair values increases when:
 • Market observable information is less readily available
 • The use of different valuation assumptions may

 have a material effect on the assets' fair values
 • Changing market conditions could materially affect the fair value of investments
 The determination of the amount of credit losses varies by investment type and is based on ongoing evaluation and assessment of known and inherent risks associated with the respective asset class or investment.
 Such evaluations and assessments are highly judgmental and are revised as conditions change and new information becomes available.
 We update our evaluations regularly and reflect changes in credit losses in our results of operations. Our conclusions may ultimately prove to be incorrect as assumptions, facts and circumstances change. When estimating credit loss allowances, historical loss trends, consideration of current conditions, and forecasts may not be indicative of future changes in credit losses and additional amounts may need to be recorded in the future.
 Our participation in indemnification programs subjects us to the risk that reimbursement for qualifying claims and claims expenses may not be received
 Participation in state-based industry pools, facilities and associations may have a material, adverse effect on our results of operations and financial condition. Our largest exposure is associated with the Michigan Catastrophic Claim Association ("MCCA"), a state-mandated indemnification mechanism for qualified personal injury protection losses that exceed a specified level. To the extent the MCCA's current and future assessments are insufficient to reimburse its ultimate obligation on existing claims to member companies, our ability to obtain the 100% indemnification of ultimate losses could be impaired. We also participate in the Federal Government National Flood Insurance Program.
 For further discussion of these items, see Regulation section, Indemnification Programs and Note 11 of the consolidated financial statements.
 We may not be able to mitigate the impact associated with changes in capital requirements
 Regulatory requirements affect the amount of capital to be maintained by our subsidiary insurance companies. Changes to requirements or regulatory interpretations may result in additional capital held in our insurance companies and could require us to increase prices, reduce our sales of certain products, or accept a return on equity below original levels assumed in pricing.
 A downgrade in financial strength ratings may have an adverse effect on our business
 Financial strength ratings are important factors in establishing the competitive position of insurance companies and their access to capital markets. Rating agencies have and could downgrade or change the outlook on our ratings in the future due to:

 24 www.allstate.com

 • Changes in the financial profile of one of our insurance companies
 • Changes in a rating agency's determination of the amount of capital required to maintain a particular rating
 • Increases in the perceived risk of our investment portfolio, a reduced confidence in management or our business strategy, or other considerations that may or may not be under our control
 A downgrade in our ratings could have an adverse effect on our sales, competitiveness, customer retention, the marketability of our product offerings, liquidity, access to and cost of borrowing or refinancing our existing debt obligations, results of operations and financial condition.

 Business, strategy and operations

 We operate in markets that are highly competitive
 Markets in which we operate are highly competitive, and we must continually allocate resources to refine and improve products and services to maintain our reputation, enhance brand perception, and remain competitive. If we are unsuccessful in generating new business, retaining customers or renewing contracts, our ability to maintain or increase premiums written or the ability to sell our products could be adversely impacted.
 Determining competitive position is complicated in the auto and homeowners insurance business as companies use different underwriting standards to accept new customers and quotes and close rates can fluctuate across companies and locations. Pricing of products is driven by multiple factors, including loss expectations, expense structure and dissimilar return targets. Additionally, sophisticated pricing algorithms make it difficult to determine what price potential customers would pay across competitors.
 There is also significant competition for producers, such as exclusive and independent agents and their licensed sales professionals. Growth and retention may be materially affected if we are unable to attract and retain effective producers or if those producers are unable to attract and retain their licensed sales professionals or customers.
 Our ability to adequately and effectively price our products is affected by the evolving nature of consumer needs and preferences, market and regulatory dynamics, broader use of telematics-based rate segmentation and potential change in consumer demand.
 Many voluntary benefits contracts are renewed annually and consumer protection plan contracts are generally multi-year, but renewals occur on a rolling basis. There is a risk that employers and retailers may be able to obtain more favorable terms from competitors than they could by renewing coverage with us. These competitive pressures may adversely

 affect the renewal of these contracts, as well as our ability to sell products.
 Changing consumer preferences may adversely impact the demand for our products which may adversely impact our business
 Growth and retention may be impacted if customer preferences change and we are unable to effectively adapt our business model and processes, including maintaining competitive products and allowing consumers to interact with us how they choose. Our business could be impacted by our ability to attract and retain customers through distribution channels that they prefer.
 Our business may also be adversely impacted by new or changing technologies
 Technological changes, such as autonomous or partially autonomous vehicles or technologies that facilitate ride, car or home sharing could disrupt the demand for products from current customers, create coverage issues, impact the frequency or severity of losses, or reduce the size of the automobile insurance market causing our auto insurance business to decline. Since auto insurance constitutes a significant portion of our overall business, we may be more sensitive than other insurers and more adversely affected by trends that could decrease auto insurance rates or reduce demand for auto insurance over time.
 Technological advancements and innovation are occurring in distribution, underwriting, claims and operations at a rapid pace that may continue to accelerate. Nontraditional competitors could enter the insurance market and further accelerate these trends. Our competitive position could be impacted if we are unable to deploy, in a cost effective and competitive manner, technology such as artificial intelligence, large language models and machine learning that collects and analyzes data to inform underwriting or other decisions, or if our competitors collect and use data which we do not have the ability to access or use. Innovations must be implemented in compliance with applicable insurance regulations and in a responsible and compliant manner. These changes may require extensive modifications to our systems and processes and extensive coordination with and reliance on the systems and operations of third parties. If we are unable to adapt to or bring such advancements and innovations to market, the quality of our products, our relationships with customers and agents, competitive position and business prospects may be materially affected. Changes in technology related to collection and application of data regarding customers could expose us to regulatory or legal actions and may have a material adverse effect on our business, reputation, results of operations and financial condition.
 Changes in technology and customer preferences may impact the ways in which we interact, do business with our customers and design our products. We may not be able to respond effectively or in a timely manner to these changes, including developing and deploying customer-facing technology to address these changing preferences and maintaining competitive technology,

 The Allstate Corporation 25

 which could have an adverse effect on our results of operations and financial condition.
 Executing our strategy to advance and innovate technology has and may continue to impact our workforce as we require new and different skills, particularly those in areas such as digital, data and analytics and technology to achieve our strategic goals. Advancements in technology and changes in consumer preferences may also impact our workforce needs in the future.
 Transformative Growth strategy implementation may not be effective
 The Transformative Growth strategy is to accelerate growth by improving customer value, expanding customer access, increasing sophistication and investment in customer acquisition, modernizing the technology ecosystem and driving organizational transformation. Implementation is focused on the property-liability businesses and impacts all aspects of Allstate's customer experience and business model, spanning product distribution and sales, operations and servicing, and claims processing. As part of the strategy, we have developed and continue to develop new insurance and non-insurance products and services to provide affordable, simple, and connected protection through multiple distribution channels. We have also expanded our product and service offerings through acquisitions and may continue to do so. If the strategy is not implemented effectively, customer retention and policy growth objectives could be adversely impacted. Lost business opportunities may result due to slower than anticipated speed to market. New products and services may not be as profitable as our existing products, may not perform as well as we expect and may change our risk exposures. External forces including competitor actions or regulatory changes may also have an adverse effect on the value generated from the transformation.
 Our catastrophe management strategy may adversely affect premium growth
 Catastrophe risk management actions have led us to reduce the size of our homeowners business, including customers with auto and other personal lines products and may negatively impact future sales. Adjustments to our business structure, size and underwriting practices in markets with significant severe weather and catastrophe risk exposure could adversely impact premium growth rates and retention.
 The ability of our subsidiaries to pay dividends may affect our liquidity and ability to meet our obligations
 The Allstate Corporation is a holding company with no significant operations. Its principal assets are the stock of its subsidiaries and its directly held cash and investment portfolios. Its liabilities include debt and pension and other postretirement benefit obligations related to employees. State insurance regulatory authorities limit the payment of dividends by insurance subsidiaries, as described in Note 17 of the consolidated financial statements. The limitations are based on statutory income and surplus. In addition, competitive pressures generally require the

 subsidiaries to maintain insurance financial strength ratings. These restrictions and other regulatory requirements may affect the ability of subsidiaries to make dividend payments. Limits on the ability of the subsidiaries to pay dividends could adversely affect holding company liquidity, including the ability to pay dividends to shareholders, service debt or complete share repurchase programs as planned.
 Changes in regulatory or rating agency capital requirements could decrease deployable capital and potentially reduce future dividends paid by our insurance companies.
 For a discussion of capital requirements, see Regulation section, Limitations on Dividends by Insurance Subsidiaries.
 Our ability to pay dividends or repurchase stock is subject to limitations under terms of certain of our securities
 The terms of the outstanding subordinated debentures prohibit us from declaring or paying any dividends or distributions on our common or preferred stock or redeeming, purchasing, acquiring or making liquidation payments on our common stock or preferred stock if we have elected to defer interest payments on the subordinated debentures, subject to certain limited exceptions.
 If the full preferred stock dividends for all preceding dividend periods have not been declared and paid, we generally may not repurchase or pay dividends on common stock during any dividend period while our preferred stock is outstanding.
 See Note 13 of the consolidated financial statements.
 Reinsurance may be unavailable at current levels and prices, which may limit our ability to write new business
 Market conditions impact the availability and cost of the reinsurance we purchase. Reinsurance may not remain continuously available to us to the same extent and on the same terms and rates as were historically available or is currently available. Our ability to economically justify reinsurance to reduce our catastrophe risk in designated areas may depend on our ability to adjust premium rates to fully or partially recover cost. If we cannot maintain our current level of reinsurance or purchase new reinsurance protection in amounts we consider sufficient at acceptable prices, we would have to either accept an increase in our catastrophe exposure, reduce our insurance exposure or seek other alternatives.
 Unfavorable conditions in the insurance-linked securities ("ILS") market may increase the cost to use ILS or issue new securities in amounts we consider sufficient at acceptable prices.

 26 www.allstate.com

 Reinsurance subjects us to counterparty risk and may not be adequate to protect us against losses arising from ceded insurance
 Collecting from reinsurers is subject to uncertainty arising from factors that include:
 • Whether reinsurers, their affiliates or certain indemnitors have the financial capacity and willingness to make payments under the terms of a reinsurance treaty or contract
 • Whether insured losses meet the qualifying conditions of the reinsurance contract
 Our inability to recover from a reinsurer could have a material effect on our results of operations and financial condition.
 Acquisitions or divestitures of businesses may not produce anticipated benefits, resulting in operating difficulties, unforeseen liabilities or asset impairments
 The ability to achieve certain anticipated financial benefits from the acquisition of businesses depends in part on our ability to successfully grow and integrate the businesses consistent with our anticipated acquisition economics. Financial results could be adversely affected by unanticipated performance issues, unforeseen liabilities, transaction-related charges, diversion of management time and resources to acquisition integration challenges or growth strategies, loss of key employees, challenges in integrating information technology systems of acquired companies with our own, amortization of expenses related to intangibles, charges for impairment of long-term assets or goodwill and indemnifications.
 Acquired businesses may not perform as projected, cost savings anticipated from the acquisition may not materialize, and costs associated with the integration may be greater than anticipated. As a result, if we do not manage these integrations effectively, the quality of our products as well as our relationships with customers and partners may result in the company not achieving returns on its investment at the level projected at acquisition.
 We also may divest businesses from time to time. These transactions may result in continued financial involvement in the divested businesses, such as through reinsurance, guarantees or other financial arrangements, following the transaction. If the acquiring companies do not perform under the arrangements, our financial results could be negatively impacted.
 We may be subject to the risks and costs associated with intellectual property infringement, misappropriation and third-party claims
 We rely on a combination of contractual rights and copyright, trademark, patent and trade secret laws to establish and protect our intellectual property. Third parties may infringe or misappropriate our intellectual property. We may have to litigate to enforce and protect intellectual property and to determine its scope, validity or enforceability, which could divert significant resources and prove unsuccessful. An

 inability to protect intellectual property or an inability to successfully defend against a claim of intellectual property infringement could have a material effect on our business.
 We may be subject to claims by third parties for patent, trademark or copyright infringement or breach of usage rights. Any such claims and any resulting litigation could result in significant expense and liability. If third-party providers or we are found to have infringed a third-party intellectual property right, either of us could be enjoined from providing certain products or services or from utilizing and benefiting from certain methods, processes, copyrights, trademarks, trade secrets or licenses. Alternatively, we could be required to enter into costly licensing arrangements with third parties or implement costly work-arounds. Any of these scenarios could have a material effect on our business and results of operations.
 Loss of key vendor relationships, disruptions to the provision of products or services by a vendor, or failure of a vendor to provide and protect reliable data, and proprietary information, or personal information of our customers, claimants or employees could adversely affect our operations
 We rely on services and products provided by many vendors in the U.S. and abroad. These include vendors of computer hardware, software, cloud technology and software as a service, as well as vendors or outsourcing of services such as:
 • Claim and administrative services
 • Call center services for customer support
 • Human resource benefits management
 • Information technology support
 • Investment management services
 • Financial and business support services
 We continue to identify ways to improve operating efficiency and reduce cost, which may result in additional outsourcing arrangements in the future. If we are not successful transitioning work to a vendor or a key vendor becomes unable to continue to provide products or services, fails to meet service level standards, or if any vendor fails to protect our confidential, proprietary, and other information, or if our business continuity plans do not sufficiently address a vendor-related business interruption, we may suffer operational impairments and financial losses.
 Our ability to attract, develop, and retain talent to maintain appropriate staffing levels and establish a successful work culture is critical to our success
 Competition for qualified employees with highly specialized knowledge in areas such as underwriting, data and analytics, technology and e-commerce, is intense and we have experienced increased competition in hiring and retaining employees. The increased prevalence of remote-working arrangements that do not require employees to relocate to take a new job could contribute to higher turnover.

 The Allstate Corporation 27

 Factors that affect our ability to attract and retain such employees include:
 • Compensation and benefits
 • Training and re-skilling programs
 • Reputation as a successful business with a culture of fair hiring, and of training and promoting qualified employees
 • Recognition of and response to changing trends and other circumstances that affect employees
 The unexpected loss of key personnel could have a material adverse impact on our business because of the loss of their skills, knowledge of our products and offerings and years of industry experience and, in some cases, the difficulty of promptly finding qualified replacement personnel.

 Macro, regulatory and risk environment

 Conditions in the global economy and capital markets could adversely affect our business and results of operations
 Global economic and capital market conditions could adversely impact demand for our products, returns on our investment portfolio and results of operations. The conditions that would have the largest impact on our business include:
 • Low or negative economic growth
 • Interest rate levels
 • Rising inflation increasing claims and claims expense
 • Substantial increases in delinquencies or defaults on debt
 • Significant downturns in the market value or liquidity of our investment portfolio
 • Prolonged downturn in equity valuations
 • Reduced consumer spending and business investment
 Stressed conditions, volatility and disruptions in global capital markets or financial asset classes could adversely affect our investment portfolio. Our assumptions about portfolio diversification may not hold across market conditions, which could lead to heightened investment losses.
 Capital and credit market conditions may significantly affect our ability to meet liquidity needs or obtain credit on acceptable terms
 In periods of extreme volatility and disruption in the capital and credit markets, liquidity and credit capacity may be severely restricted. Our access to additional financing depends on a variety of factors such as market conditions, the general availability of credit, the overall availability of credit to our industry, our credit ratings and credit capacity, as well as lenders' perception of our long- or short-term financial prospects. In such circumstances, our ability to obtain capital to fund operating expenses, financing costs,

 capital expenditures or acquisitions may be limited, and the cost of any such capital may be significant.
 A large-scale pandemic, the occurrence of terrorism, military actions, social unrest or other actions may have an adverse effect on our business
 A large-scale pandemic, such as the Coronavirus and its impacts, the occurrence of terrorism, military actions, social unrest or other actions, may result in loss of life, property damage, and disruptions to commerce and reduced economic activity. Some of the assets in our investment portfolio may be adversely affected by declines in the equity markets, changes in interest rates, reduced liquidity and economic activity caused by a large-scale pandemic. Additionally, a large-scale pandemic or terrorist act could have a material effect on sales, liquidity and operating results.
 While most of the risks related to the Coronavirus have moderated, some longer-term impacts remain, such as supply chain disruptions, labor shortages, and other macroeconomic factors that have increased inflation and asset values. These factors have affected our operations and may continue to significantly affect our results of operations, financial condition and liquidity and should be considered when comparing the current period to prior periods.
 See MD&A, Highlights for a summary of the impacts on our operations, each of our segments and investments that may continue, emerge, evolve or accelerate into 2024.
 The failure in cyber or other information security controls, as well as the occurrence of events unanticipated in our disaster recovery processes and business continuity planning, could result in a loss or disclosure of confidential information, damage to our reputation, additional costs and impair our ability to conduct business effectively
 We depend heavily on computer systems, mathematical algorithms and data to perform necessary business functions. There are threats that could impact our ability to protect our data and systems; if the threats materialize, they could impact confidentiality, integrity and availability:
 • Confidentiality — protecting our data from disclosure to unauthorized parties
 • Integrity — ensuring data is not changed accidentally or without authorization and is accurate
 • Availability — ensuring our data and systems are accessible to meet our business needs
 We collect, use, store or transmit a large amount of confidential, proprietary and other information (including personal information of customers, claimants or employees) in connection with the operation of our business. Systems are subject to increased cyberattacks and unauthorized access, such as physical and electronic break-ins or unauthorized tampering.

 28 www.allstate.com

 We constantly defend against threats to our data and systems, including malware and computer virus attacks, unauthorized access, system failures and disruptions. We have experienced breaches of our data and systems, although to date none of these breaches has had a material effect on our business, operations or reputation. Events like these jeopardize the information processed and stored in, and transmitted through, our computer systems and networks and otherwise cause interruptions or malfunctions in our operations, which could result in damage to our reputation, financial losses, litigation, increased costs, regulatory penalties or customer dissatisfaction.
 These risks may increase in the future as threats become more sophisticated and we continue to expand internet and mobile strategies, develop additional remote connectivity solutions to serve our employees and customers, develop and expand products and services designed to protect customers' digital footprint, and build and maintain an integrated digital enterprise.
 Our increased use of third-party services (e.g., cloud technology and software as a service) can make it more difficult to identify and respond to cyberattacks in any of the above situations. Although we may review and assess third-party vendor cyber security controls, our efforts may not be successful in preventing or mitigating the effects of such events. Third parties to whom we outsource certain functions are also subject to cybersecurity risks.
 Personal information is subject to an increasing number of federal, state, local and international laws and regulations regarding privacy and data security, as well as contractual commitments. Any failure or perceived failure by us to comply with such obligations may result in governmental enforcement actions and fines, litigation or public statements against us by consumer advocacy groups or others and could cause our employees and customers to lose trust in us, which could have an adverse effect on our reputation and business.
 Our integrated operational risk and return management processes and practices may not be sufficient to timely detect and mitigate operational risks, including those posed by third-party service providers, that could have an adverse effect on our reputation and business.
 See the Regulation section, Privacy Regulation and Data Security, for additional information.
 The occurrence of a disaster or event that results in the shut-down, disruption, degradation or unavailability of one or more of our systems or facilities, unanticipated problems with our disaster recovery processes, or a support failure from external providers, could have an adverse effect on our ability to conduct business and on our results of operations and financial condition, particularly if those events affect our computer-based data processing, transmission, storage, and retrieval systems or destroy data. If a significant number of employees were unavailable or unable to access our systems in the

 event of a disaster, our ability to effectively conduct business could be severely compromised.
 Losses from changing climate and weather conditions may adversely affect our financial condition, profitability or cash flows
 Climate change affects the occurrence of certain natural events, such as increasing the frequency or severity of wind, tornado, hailstorm and thunderstorm events due to increased convection in the atmosphere. There could also be more frequent wildfires in certain geographies, more flooding and the potential for increased severity of hurricanes. As a result, incurred losses from such events and the demand, price and availability of reinsurance coverages for automobile and homeowners insurance may be affected.
 Climate change may also impact insurability by impairing our ability to identify and quantify potential hazards that will result in losses and offer our customers products at an affordable price. Our investment portfolio is also subject to the effects of climate change as economic shifts alter the return dynamic of long-term investments and increase valuation risk.
 Due to significant variability associated with future changing climate conditions, we are unable to predict the impact climate change will have on our businesses.
 Our efforts to meet evolving environmental, social, and governance standards may not meet stakeholders' expectations
 Some of our existing or potential investors, customers, employees, regulators, and other stakeholders evaluate our business practices according to a variety of environmental, social and governance ("ESG") standards and expectations, including those related to climate change, inclusive diversity and equity, data privacy, and the well-being of our employees. Some regulators have proposed or adopted, or may propose or adopt, pro- or anti-ESG rules or standards applicable to our business.
 Our business practices and disclosures are evaluated against ESG standards which are continually evolving and not always well defined or readily measurable today. ESG-related expectations may also reflect contrasting or conflicting values or agendas. Our practices may not change in the particular ways or at the rate stakeholders expect. We may fail to meet our commitments or targets. Our policies and processes to evaluate and manage ESG priorities in coordination with other business priorities may not prove completely effective or fully satisfy our stakeholders. Customers and potential customers may choose not to do business with us based on our ESG practices and related policies and actions. We may face adverse regulatory, investor, media, or public scrutiny leading to business, reputational, or legal challenges.

 The Allstate Corporation 29

 We are subject to extensive regulation, and potential further restrictive regulation may increase operating costs and limit growth
 We largely operate in the highly regulated insurance and broader financial services sectors and are subject to extensive laws and regulations that are complex and subject to change. Changes may lead to additional expenses, increased legal exposure, or increased reserve or capital requirements limiting our ability to grow or to achieve targeted profitability. Moreover, laws and regulations are administered and enforced by governmental authorities that exercise interpretive latitude, including:
 • State insurance regulators
 • State securities administrators
 • State attorneys general
 • Federal agencies including the SEC, the Financial Industry Regulatory Authority, the Department of Labor, the U.S. Department of Justice, the Consumer Financial Protection Bureau and the National Labor Relations Board
 Consequently, compliance with one regulator's or enforcement authority's interpretation of a legal issue may not result in compliance with another's interpretation of the same issue.
 There is risk that one regulator's or enforcement authority's interpretation of a legal issue may change to our detriment. There is also a risk that changes in the overall legal environment may cause us to change our views regarding the actions we need to take from a legal risk management perspective. This could necessitate changes to our practices that may adversely impact our business. In some cases, state insurance laws and regulations are generally intended to protect or benefit purchasers or users of insurance products, not holders of securities that we issue. These laws and regulations may limit our ability to grow or to improve the profitability of our business.
 We have business process and information technology operations in Canada, India, the United Kingdom and Mexico that are subject to operating, regulatory and political risks in those countries. We also outsource certain business functions to vendors located in foreign countries, including India, Mexico, Colombia, South Africa and the Philippines, that are subject to operating, regulatory and political risks in those countries. We may incur substantial costs and other negative consequences if any of these risks occur, including an adverse effect on our business, results of operations and financial condition.
 A regulatory environment that requires rate increases to be approved, can dictate underwriting practices and mandate participation in loss sharing arrangements, may adversely affect results of operations and financial condition
 Political events and positions can affect the insurance market, including efforts to suppress rates to a level that may not allow us to reach targeted levels of profitability. Regulatory challenges to rate increases, especially during inflationary periods with more

 significant rate changes, may restrict rate changes that may be required to achieve targeted levels of profitability and returns on equity. If we are unsuccessful, our results of operations could be negatively impacted. Certain states may enact regulatory reforms regarding insurance rating that may make it more difficult to obtain rates that appropriately reflect the risk.
 In addition, certain states have enacted laws that require an insurer conducting business in that state to participate in assigned risk plans, reinsurance facilities and joint underwriting associations. Certain states also require the insurer to offer coverage to all consumers, often restricting an insurer's ability to charge the price it might otherwise charge for the risk acceptance. In these markets, we may be compelled to underwrite significant amounts of business at lower-than-desired rates, possibly leading to an unacceptable return on equity. Alternatively, as the facilities recognize a financial deficit, they could have the ability to assess participating insurers, adversely affecting our results of operations and financial condition. Laws and regulations of many states also limit an insurer's ability to withdraw from one or more lines of insurance, except pursuant to a plan that is approved by the state insurance department. Certain states require an insurer to participate in guaranty funds for impaired or insolvent insurance companies. These funds periodically assess losses against all insurance companies doing business in the state. Our results of operations and financial condition could be adversely affected by any of these factors.
 Regulatory reforms, and the more stringent application of existing regulations, may make it more expensive for us to conduct our business
 The federal government has enacted and continues to propose comprehensive regulatory reforms for financial services entities. As part of a larger effort to strengthen the regulation of the financial services market, certain reforms are applicable to the insurance industry. A growing number of state laws, enforced by a variety of regulators, on issues such as privacy and cybersecurity may also increase expenses and require additional compliance activities.
 The Federal Insurance Office and Financial Stability Oversight Council have been established, and the federal government may enact reforms that affect the state insurance regulatory framework. The potential impact of state or federal measures that change the nature or scope of insurance and financial regulation is uncertain but may make it more expensive for us to conduct business and limit our ability to grow or achieve profitability.
 Losses from legal and regulatory actions may be material to our results of operations, cash flows and financial condition
 We are involved in various legal actions, including class-action litigation challenging a range of company practices; including coverages provided by our insurance products, some of which involve claims for substantial or indeterminate amounts. We are also

 30 www.allstate.com

 involved in various regulatory actions and inquiries, including market conduct exams by state insurance regulatory agencies. In the event of an unfavorable outcome in any of these matters, the ultimate liability may be more than amounts currently accrued or disclosed in our reasonably possible loss range and may be material to our results of operations, cash flows and financial condition.
 See Note 15 of the consolidated financial statements.
 Changes in or the application of accounting standards issued by standard-setting bodies and changes in tax laws may adversely affect our results of operations and financial condition
 Our financial statements are subject to GAAP, which are periodically revised, interpreted or expanded. Accordingly, we may be required to adopt new guidance or interpretations, which may have a material effect on our results of operations and financial condition and could adversely impact financial strength ratings.
 • Market declines, changes in business strategies or other events impacting the fair value of goodwill or purchased intangible assets could result in an impairment charge to income
 • Realization of our deferred tax assets assumes that we can fully utilize the deductions recognized for tax purposes; we may recognize additional tax expense if these assets are not fully utilized
 • New tax legislative initiatives may be enacted that may impact our effective tax rate and could adversely affect our tax positions or tax liabilities
 See the Regulation section, MD&A, Application of Critical Accounting Estimates and Note 2 of the consolidated financial statements for further details.
 Misconduct or fraudulent acts by employees, agents and third parties may expose us to financial loss, disruption of business, regulatory assessments and reputational harm
 The company and the insurance industry are susceptible to past and future misconduct or fraudulent activities by employees, representative agents, vendors, customers and other third parties. These activities could include:
 • Fraud against the company, its employees and its customers through illegal or prohibited activities
 • Unauthorized acts or representations, unauthorized use or disclosure of personal or proprietary information, deception, and misappropriation of funds or other benefits

 2023 Highlights
 Overview
 The following discussion highlights significant factors influencing the consolidated financial position and results of operations of The Allstate Corporation (referred to in this document as "we," "our," "us," the "Company" or "Allstate"). It should be read in conjunction with the consolidated financial statements and related notes found under Item 8. contained herein.
 A discussion of strategy, including updates to the multi-year Transformative Growth initiative, can be found in Part 1, Item 1. Business.
 This section of this Form 10-K generally discusses 2023 and 2022 results and year-to-year comparisons between 2023 and 2022. Discussions of 2021 results and year-to-year comparisons between 2022 and 2021 that are not included in this Form 10-K can be found in Management's Discussion and Analysis ("MD&A") in Part II, Item 7 of our annual report on Form 10-K for 2022, filed February 16, 2023. Certain amounts have been reclassified or recast to reflect the application of the new guidance to all in-scope long-duration insurance contracts and to conform to current year presentation.
 The most important factors we monitor to evaluate the financial condition and performance for our reportable segments and the Company include:
 • Allstate Protection: premium, policies in force ("PIF"), new business sales, policy retention, price changes, claim frequency and severity, catastrophes, loss ratio, expenses, underwriting results and combined ratio
 • Protection Services: revenues, premium written, PIF and adjusted net income
 • Allstate Health and Benefits: premiums, other revenue, new business sales, PIF, benefit ratio, expenses and adjusted net income
 • Investments: exposure to market risk, asset allocation, credit quality, total return, net investment income, cash flows, net gains and losses on investments and derivatives, unrealized capital gains and losses, long-term returns and asset duration
 • Financial condition: liquidity, parent holding company deployable assets, financial strength ratings, operating leverage, debt levels, book value per share and return on equity

 Measuring segment profit or loss
 The measure of segment profit or loss used in evaluating performance is underwriting income for the Allstate Protection and Run-off Property-Liability segments and adjusted net income for the Protection Services, Allstate Health and Benefits, and Corporate and Other segments.
 Underwriting income is calculated as premiums earned and other revenue, less claims and claims expense ("losses"), Shelter-in-Place Payback expense, amortization of deferred policy acquisition costs ("DAC"), operating costs and expenses, amortization or impairment of purchased intangibles, and restructuring and related charges, as determined using accounting principles generally accepted in the United States of America ("GAAP"). We use this measure in our evaluation of results of operations to analyze profitability.
 Adjusted net income is net income (loss) applicable to common shareholders, excluding:

 •
 Net gains and losses on investments and derivatives

 •
 Pension and other postretirement remeasurement gains and losses

 •
 Business combination expenses and the amortization or impairment of purchased intangibles

 •
 Income or loss from discontinued operations

 •
 Gain or loss on disposition

 •
 Adjustments for other significant non-recurring, infrequent or unusual items, when (a) the nature of the charge or gain is such that it is reasonably unlikely to recur within two years, or (b) there has been no similar charge or gain within the prior two years

 •
 Income tax expense or benefit on reconciling items

 Macroeconomic Impacts
 Macroeconomic factors have and may continue to impact the results of our operations, financial condition and liquidity, such as U.S. government fiscal and monetary policies, banking system instability, the Russia/Ukraine and Israel/Hamas conflicts and the remaining impacts of the Novel Coronavirus Pandemic or COVID-19 ("Coronavirus"), such as supply chain disruptions, labor shortages and other macroeconomic factors that have increased inflation.
 Inflation continues to remain elevated, which led to increases in interest rates by the Federal Reserve and many foreign governmental authorities and central banks. These actions could create significant economic uncertainty. Market volatility resulting from these factors and from disruptions in the banking industry have and may continue to impact our investment valuations and returns.
 These factors have affected our operations and may continue to significantly affect our results of operations, financial condition and liquidity and should be considered when comparing the current period to prior periods. Macroeconomic impacts are disclosed in Part 1 "Item 1A. Risk Factors'', including the risk factors titled "A large-scale pandemic, the occurrence of terrorism, military actions, social unrest or other actions may have an adverse effect on our business" and "Conditions in the global economy and capital markets could adversely affect our business and results

 of operations". This is not inclusive of all potential impacts and should not be treated as such. Within the MD&A, we have included further disclosures related to macroeconomic impacts on our 2023 results.
 Israel/Hamas Conflict
 As of December 31, 2023, we have approximately $47 million investment exposure in the Middle East, of which approximately $43 million is held in Israel, which is primarily indirect exposure through funds managed by external asset managers.
 Russia/Ukraine Conflict
 The Russia-Ukraine war and related sanctions imposed as a result of this conflict have increased global economic and political uncertainty, including inflationary pressures and an increased risk of cybersecurity incidents. Allstate does not have operations or direct investments in Russia, Belarus or Ukraine, but we could experience significant indirect impacts on the investment portfolio, financial position, or results of operations.
 2023 Operating Priorities and Results
 Allstate continued to focus on its operating priorities while executing a comprehensive plan to improve auto insurance profitability. The table below summarizes the results of our 2023 Operating Priorities.

 2023 Operating Priorities (1)

 Improve Customer Value

 Enterprise Net Promoter Score, which measures how likely customers are to recommend Allstate, finished below the prior year, reflecting the impact of substantial price increases necessary to offset higher loss costs.

 Grow Customer Base
 Consolidated policies in force reached 194 million, a 2.8% increase from prior year. Property-Liability policies in force decreased by 2.0% compared to the prior year, as continued growth at National General was more than offset by the Allstate brand and renewals declined in the auto insurance business.

 Protection Services policies in force increased 4.3%, primarily due to growth at Allstate Protection Plans.

 Achieve Target Economic Returns on Capital
 Return on average Allstate common shareholders' equity was (2.0)% in 2023.

 The Property-Liability combined ratio of 104.5 for the full year decreased compared to the prior year primarily reflecting increased premiums earned, partially offsetting continued high loss costs. A comprehensive profitability plan is being executed.

 Proactively Manage Investments
 Net investment income of $2.48 billion in 2023 was $75 million higher than prior year as higher market-based investment income was partially offset by lower performance-based results.

 Total return on the $66.68 billion investment portfolio was 6.7% in 2023. Proactive portfolio management repositioned the fixed income portfolio into longer duration and higher-yielding assets that sustainably increase income.

 Execute Transformative Growth

 Allstate made substantial progress in advancing Transformative Growth in 2023, including continued cost reductions, deploying a new property-liability technology platform and a new Affordable, Simple and Connected auto insurance offering in seven states.

 National General is building a strong competitive position in independent agent distribution.

 Build a digital enterprise by expanding utilization of machine-based learning and artificial intelligence.

 (1)2024 operating priorities will remain mostly consistent with the 2023 priorities.

 The Allstate Corporation 37

 Consolidated net income (loss) applicable to common shareholders

 Consolidated net loss applicable to common shareholders was $316 million in 2023 compared to net loss of $1.39 billion in 2022, primarily due to improved underwriting results and net gains on equity valuations compared to losses in 2022.
 For the twelve months ended December 31, 2023, return on Allstate common shareholders' equity was (2.0)% compared to (7.2)% for the twelve months ended December 31, 2022.

 Total revenue

 Total revenue increased 11.1% to $57.09 billion in 2023 compared to 2022, primarily due to a 10.4% increase in property and casualty insurance premiums earned and net gains on equity valuations in 2023 compared to losses in 2022.

 Net investment income increased $75 million to $2.48 billion in 2023 compared to 2022, primarily due to higher market-based income reflecting increased fixed income portfolio yields and investment balances, partially offset by lower performance-based investment results.

 Segment Highlights
 Allstate Protection underwriting loss was $2.09 billion in 2023 compared to underwriting loss of $2.78 billion in 2022, due to increased premiums earned and lower unfavorable non-catastrophe reserve reestimates, partially offset by higher incurred losses and higher catastrophe losses of $5.64 billion in 2023 compared to $3.11 billion in 2022.
 Premiums written increased 10.0% to $50.35 billion in 2023 compared to $45.79 billion in 2022, reflecting higher premiums in both Allstate and National General brands.
 Protection Services adjusted net income was $106 million in 2023 compared to $169 million in 2022. The decrease in 2023 was due to higher appliance and furniture claim severity at Allstate Protection Plans and lower third-party lead sales at Arity, partially offset by improved margins at Allstate Roadside and lower expenses at Allstate Identity Protection. Adjusted net income was also impacted by an increase in state income taxes and deferred tax liabilities for Allstate Dealer Services.
 Premiums and other revenues increased 9.4% or $220 million to $2.56 billion in 2023 from $2.34 billion in 2022 primarily due to Allstate Protection Plans.

 Allstate Health and Benefits adjusted net income was $242 million in 2023 compared to $245 million in 2022. The decrease was primarily due to a decline in employer voluntary benefits, partially offset by increases in individual and group health.
 Premiums and contract charges totaled $1.85 billion in 2023, an increase of 0.8% from $1.83 billion in 2022 primarily due to growth in group health, partially offset by a decline in employer voluntary benefits and individual health.
 Income Taxes
 The effective tax rate is the ratio of income tax (benefit) expense divided by (loss) income from operations before income tax expense. The effective tax rate for 2023 was 38.8% compared to 26.7% in 2022 due to the total income tax benefit measured against a lower loss from operations before income tax expense of $348 million in 2023 compared to a loss of $1.83 billion in 2022.
 In both years, the effective tax rate was higher than the 21% federal statutory income tax rate, primarily due to tax credits, tax-exempt interest income and excess tax benefits on shared-based payments, offset by a change in valuation allowance and uncertain tax positions. In addition, in 2023, the Company recorded an additional tax benefit arising from the liquidation of a foreign subsidiary and the remeasurement of state deferred income taxes. The

 The Allstate Corporation 39

 impact of the state deferred income taxes was not material to the consolidated results of operations but resulted in a tax expense to Protection Services and a tax benefit to Allstate Protection.
 For additional information, see Note 16 of the consolidated financial statements.
 Financial Highlights
 Investments totaled $66.68 billion as of December 31, 2023, increasing from $61.83 billion as of December 31, 2022.
 Allstate shareholders' equity was $17.77 billion as of December 31, 2023 and $17.49 billion as of December 31, 2022. The increase is primarily due to lower unrealized net capital losses on investments, partially offset by dividends paid to shareholders, common share repurchases and a net loss.
 Book value per diluted common share (ratio of Allstate common shareholders' equity to total common shares outstanding and dilutive potential common shares outstanding) was $59.39 as of December 31, 2023, an increase of 2.2% from $58.12 as of December 31, 2022.
 Return on average common Allstate shareholders' equity For the twelve months ended December 31, 2023, return on Allstate common shareholders' equity was (2.0)%, an increase of 5.2 points from (7.2)% for the twelve months ended December 31, 2022, primarily due to lower net loss applicable to common shareholders.
 Pension and other postretirement remeasurement gains and losses We recorded pension and other postretirement remeasurement losses of $9 million in 2023, primarily related to losses on the remeasurement of the projected benefit obligation driven by a decrease in the liability discount rate, partially offset by gains due to favorable asset performance compared to expected return on plan assets. See Note 18 of the consolidated financial statements and Application of Critical Accounting Estimates section of the MD&A for further information.
 Adopted accounting standard
 Accounting for Long-Duration Insurance Contracts Effective January 1, 2023, the Company adopted the Financial Accounting Standards Board ("FASB") guidance revising the accounting for certain long-duration insurance contracts using the modified retrospective approach to the transition date of January 1, 2021.

 Under the new guidance, measurement assumptions, including those for mortality, morbidity and policy lapses, are required to be reviewed at least annually, and updated as appropriate. In addition, reserves under the new guidance are required to be discounted using an upper-medium grade fixed income instrument yield that is updated through other comprehensive income ("OCI") at each reporting date. Additionally, deferred policy acquisition costs ("DAC") for all long-duration products are amortized on a simplified basis. Also, the Company's reserve for future policy benefits and DAC are subject to new disclosure guidance.
 In addition, the Company met the conditions included in Accounting Standards Update No. 2022-05, Transition for Sold Contracts, and elected to not apply the new guidance for contracts that were part of the 2021 sales of Allstate Life Insurance Company ("ALIC") and Allstate Life Insurance Company of New York ("ALNY").

 After-tax cumulative effect of change in accounting principle on transition date

 January 1, 2021

 Decrease in retained income

 Decrease in accumulated other comprehensive income ("AOCI")

 Total decrease in equity

 The decrease in AOCI was primarily attributable to a change in the discount rate used in measuring the reserve for future policy benefits for traditional life contracts and other long-term products with guaranteed terms from a portfolio-based rate at contract issuance to an upper-medium grade fixed income-based rate at the transition date. The decrease in retained income primarily related to certain cohorts of long-term contracts whose expected net premiums exceeded expected gross premiums which resulted in an increase in reserves and a decrease in retained income equal to the present value of expected future benefits less the present value of expected future premiums at the transition date.

 2023 Form 10-K Property-Liability

 Property-Liability Operations
 Overview Property-Liability operations consist of two reportable segments: Allstate Protection and Run-off Property-Liability. These segments are consistent with the groupings of financial information that management uses to evaluate performance and to determine the allocation of resources.
 We do not allocate Property-Liability investment income, net gains and losses on investments and derivatives, or assets to the Allstate Protection and Run-off Property-Liability segments. Management reviews assets at the Property-Liability level for decision-making purposes.
 GAAP operating ratios are used to measure our profitability to enhance an investor's understanding of our financial results and are calculated as follows:
 • Loss ratio: the ratio of claims and claims expense (loss adjustment expenses), to premiums earned. Loss ratios include the impact of catastrophe losses and prior year reserve reestimates.
 • Expense ratio: the ratio of amortization of DAC, operating costs and expenses, amortization or impairment of purchased intangibles, restructuring and related charges and Shelter-in-Place Payback expense, less other revenue to premiums earned.
 • Combined ratio: the sum of the loss ratio and the expense ratio.
 We have also calculated the following impacts of specific items on the GAAP operating ratios because of the volatility of these items between periods. The impacts are calculated by taking the specific items noted below divided by Property-Liability premiums earned:
 • Effect of catastrophe losses on combined ratio: includes catastrophe losses and prior year reserve reestimates of catastrophe losses included in claims and claims expense
 • Effect of prior year reserve reestimates on combined ratio
 • Effect of amortization of purchased intangibles on combined ratio
 • Effect of restructuring and related charges on combined ratio
 • Effect of Shelter-in-Place Payback expense on combined and expense ratios
 • Effect of Run-off Property-Liability business on combined ratio: includes claims and claims expense, restructuring and related charges and operating costs and expenses in the Run-off Property-Liability segment

 Premium measures and statistics are used to analyze our premium trends and are calculated as follows:
 • PIF: policy counts are based on items rather than customers. A multi-car customer would generate multiple item (policy) counts, even if all cars were insured under one policy. Commercial lines PIF counts for shared economy agreements typically reflect contracts that cover multiple rather than individual drivers. Lender-placed policies are excluded from policy counts because relationships are with the lenders.
 • New issued applications: item counts of automobile or homeowner insurance applications for insurance policies that were issued during the period, regardless of whether the customer was previously insured by another Allstate brand.
 • Average premium-gross written ("average premium"): gross premiums written divided by issued item count. Gross premiums written include the impacts from discounts, surcharges and ceded reinsurance premiums and exclude the impacts from mid-term premium adjustments and premium refund accruals. Average premiums represent the appropriate policy term for each line.
 • Renewal ratio: renewal policy item counts issued during the period, based on contract effective dates, divided by the total policy item counts issued generally 6 months prior for auto or 12 months prior for homeowners.
 • Implemented rate changes: represents the impact in the locations (U.S. states, the District of Columbia or Canadian provinces) where rate changes were implemented during the period as a percentage of total brand prior year-end premiums written.
 Frequency and severity statistics, which are influenced by driving patterns, inflation and other factors, are provided to describe the trends in loss costs. Our reserving process incorporates changes in loss patterns, operational statistics and changes in claims reporting processes to determine our best estimate of recorded reserves. We use the following statistics to evaluate losses:
 • Gross claim frequency is calculated as annualized notice counts, excluding counts associated with catastrophe events, received in the period divided by the average of PIF with the applicable coverage during the period. Gross claim frequency includes all actual notice counts, regardless of their current status (open or closed) or their ultimate disposition (closed with a payment or closed without payment).
 • Report year incurred claim severity is calculated by dividing the sum of recorded estimated incurred losses and allocated loss adjustment expenses, excluding catastrophes, by the reported notice counts during that report year. Report year incurred claim severity does not include incurred

 The Allstate Corporation 41

 2023 Form 10-K Property-Liability

 but not reported ("IBNR") losses or benefits from subrogation and salvage.
 • Paid claim severity is calculated by dividing the sum of paid losses and loss expenses by claims closed with a payment during the period.
 • Percent change in frequency or paid claim severity statistics are calculated as the amount of increase or decrease in gross claim frequency or paid claim severity in the current period compared to the

 same period in the prior year divided by the prior year gross claim frequency or paid claim severity.
 • Percent change in report year incurred claim severity statistic is calculated as the amount of increase or decrease in report year incurred claim severity recorded in the current year divided by the current estimate of the prior report year incurred claim severity.

 Underwriting loss improved to $2.09 billion in 2023 compared to $2.78 billion in 2022, primarily due to increased premiums earned and lower unfavorable non-catastrophe reserve reestimates, partially offset by higher losses. We are executing a comprehensive plan to improve auto insurance profitability, by raising rates, reducing operating expenses and advertising, implementing underwriting restrictions in underperforming states and enhancing claims processes to manage loss costs.

 Auto insurance premiums written increased 10.7% or $3.29 billion in 2023 compared to 2022, primarily due to the following factors:
 • Increased average premiums driven by 2022 and 2023 rate increases. In the year ended December 31, 2023:
 –Rate increases of 17.9% were taken for Allstate brand in 55 locations, resulting in total Allstate brand insurance premium impact of 16.4%
 –Rate increases of 18.8% were taken for National General brand in 48 locations, resulting in total National General brand insurance premium impact of 12.8%
 • We expect to continue to pursue rate increases for both Allstate and National General brands into 2024 to improve auto insurance profitability

 • PIF decreased 2.9% or 751 thousand to 25,283 thousand as of December 31, 2023 compared to December 31, 2022
 • Renewal ratio decreased 1.6 points as of December 31, 2023 compared to December 31, 2022
 • Decreased new issued applications driven by the direct and exclusive agency channels, partially offset by growth in the independent agency channel
 • The impact of the ongoing rate increases, underwriting restrictions in markets with returns below target levels and temporary reductions in advertising have and may continue to have an adverse effect on the renewal ratio, premiums and future PIF growth

 Homeowners insurance premiums written increased 12.3% or $1.38 billion in 2023 compared to 2022, primarily due to the following factors:
 • Higher Allstate brand average premiums from implemented rate increases taken in 2022 and 2023 and inflation in insured home replacement costs, combined with policies in force growth
 • In 2023 rate increases of 15.0% were taken for Allstate brand in 49 locations, resulting in total Allstate brand insurance premium impact of 11.3%
 • National General policy growth may be negatively impacted in future quarters as we improve underwriting margins to targeted levels in the current books of business through underwriting and rate actions. In 2023 rate increases of 23.4% were taken for National General brand in 32 locations, resulting in total National General brand insurance premium impact of 11.0%

 • Decreased new issued applications in the direct and exclusive agency channels, partially offset by growth in the independent agency channel
 • Policy growth is being reduced in states and lines of business that are underperforming. We are no longer writing new homeowners business in California and Florida, and we are non-renewing certain policies in Florida to reduce our exposure, which have and will continue to negatively impact premiums
 • The impact of the ongoing rate increases, underwriting restrictions in markets with returns below target levels and temporary reductions in advertising have and may continue to have an adverse effect on the renewal ratio, premiums and future PIF growth

 Other personal lines premiums written increased 12.0% or $270 million in 2023 compared to 2022, primarily due to increases in landlords, condominiums and personal umbrella for Allstate brand. We are no longer writing condominium new business in California and Florida and we are non-renewing certain policies in Florida, which will continue to negatively impact premiums.
 Commercial lines premiums written decreased 35.9% or $404 million in 2023 compared to 2022, due to profitability actions taken to no longer offer coverage to transportation network companies unless the contracts utilize telematics-based pricing and the Allstate brand exiting traditional commercial insurance in five states, which will continue to negatively impact premiums.

 The Allstate brand commercial insurance strategy is being advanced through an equity investment and commercial partnership with NEXT Insurance, a high-growth, digital platform for small business insurance which will expand the availability of our commercial lines offerings via NEXT product portfolio.
 Other business lines premiums written increased 5.0% or $27 million in 2023 compared to 2022.

 Frequency and severity are influenced by:
 • Supply chain disruptions and labor shortages
 • Mix of repairable losses and total losses
 • Value of total losses due to changes in used car prices
 • Changes in medical inflation and consumption
 • Number of claims with attorney representation
 • Labor and part costs
 • Changes in commuting activity
 • Driving behavior (e.g., speed, time of day) impacting severity and mix of claim types
 • Organizational and process changes impacting claim opening and closing practices and shifts in timing, if any, can impact comparisons to prior periods

 The quarterly auto loss ratio has been more variable due to these and additional factors discussed below.
 Auto loss ratio decreased 4.4 points in 2023 compared to 2022 driven by increased earned premium compared to the prior year. Estimated report year 2023 incurred claim severity for Allstate brand, excluding Esurance and Canada, had a weighted average increase of between 8% to 9% compared to report year 2022 for major coverages due to higher part costs and labor rates for repairable vehicles, a higher mix of total losses, higher costs for claims with attorney representation, higher medical consumption and inflation. Gross claim frequency increased relative to the prior year. We are enhancing our claims practices to manage loss costs by increasing resources and expanding re-inspections, accelerating resolution of bodily injury claims, and negotiating improved vendor services and parts agreements.

 The Allstate Corporation 47

 Homeowners loss ratio increased 14.3 points in 2023 compared to 2022, primarily due to higher catastrophe losses and severity, partially offset by increased premiums earned.

 Gross claim frequency
 (4.2)
 %

 Paid claim severity
 11.8

 Gross claim frequency decreased in 2023 compared to 2022 primarily due to fire and water perils. Paid claim severity increased in 2023 compared to 2022 due to inflationary loss cost pressure driven by increases in labor and materials costs. Homeowner paid claim severity can be impacted by both the mix of perils and the magnitude of specific losses paid during the period.
 Other personal lines loss ratio increased 2.3 points in 2023 compared to 2022, primarily due to higher catastrophe losses and increased severity, partially offset by increased premiums earned.
 Commercial lines loss ratio decreased 14.9 points in 2023 compared to 2022 primarily due to the result of profitability actions taken and lower unfavorable reserve reestimates, partially offset by continued elevated frequency and severity.

 Other business lines loss ratio increased 8.9 points in 2023 compared to 2022 primarily due to higher non-catastrophe losses and unfavorable prior year reserve reestimates.
 Catastrophe losses increased 81.1% or $2.52 billion in 2023 compared to 2022 primarily related to an increased number of wind/hail events and larger losses per event.
 Reinsurance recoveries in 2021 related to the Nationwide Aggregate Reinsurance Program for aggregate catastrophe losses occurring between April 1, 2020 and December 31, 2020, which primarily impacted homeowners prior year reserve reestimates.
 We define a "catastrophe" as an event that produces pre-tax losses before reinsurance in excess of $1 million and involves multiple first party policyholders, or a winter weather event that produces a number of claims in excess of a preset, per-event threshold of average claims in a specific area, occurring within a certain amount of time following the event. Catastrophes are caused by various natural events including high winds, winter storms and freezes, tornadoes, hailstorms, wildfires, tropical storms, tsunamis, hurricanes, earthquakes and volcanoes.
 We are also exposed to man-made catastrophic events, such as certain types of terrorism, civil unrest, wildfires or industrial accidents. The nature and level of catastrophes in any period cannot be reliably predicted.

 Catastrophe management
 Historical catastrophe experience For the last ten years, the average annual impact of catastrophes on our loss ratio was 8.3 points, but it has varied from 5.7 points to 11.6 points. The average annual impact of catastrophes on the homeowners loss ratio for the last ten years was 27.1 points. Over time, we have limited our aggregate insurance exposure to catastrophe losses in certain regions of the country that are subject to high levels of natural catastrophes by our participation in various state facilities. For further discussion of these facilities, see Note 15 of the consolidated financial statements. However, the impact of these actions may be diminished by the growth in insured values, the effect of state insurance

 laws and regulations and we may not be able to maintain our current level of reinsurance or purchase new reinsurance protection in amounts we consider sufficient at acceptable prices. In addition, in various states we are required to participate in assigned risk plans, reinsurance facilities and joint underwriting associations that provide insurance coverage to individuals or entities that otherwise are unable to purchase such coverage from private insurers. Because of our participation in these and other state facilities such as wind pools, we may be exposed to losses that surpass the capitalization of these facilities and to assessments from these facilities.

 48 www.allstate.com

 We have continued to take actions to maintain an appropriate level of exposure to catastrophic events while continuing to meet the needs of our customers, including the following:
 • Continuing to limit or not offer new homeowners, manufactured home and landlord package policy business in certain coastal geographies. Additionally, we:
 –Wrote a limited number of homeowners policies in select areas of California from 2016 to 2022, but are no longer writing new homeowners and condominium business in the state of California. We may take further action to reduce our exposure.
 –Reduced our exposure to high risk areas, including California and Florida. Since December 31, 2022, PIF has declined by an average of approximately 7% in those two states.
 –Write homeowners coverage, excluding in Florida, through our excess and surplus lines carrier, North Light Specialty Insurance Company ("North Light"), which includes earthquake coverage (other than fire following earthquakes) that is currently ceded via quota share reinsurance.
 • Increased capacity in our brokerage platform for customers not offered an Allstate policy. As of December 31, 2023, Ivantage had $2.19 billion non-proprietary premiums under management.
 • Ceded wind exposure related to insured property located in wind pool eligible areas in certain states.
 • Generally require higher deductibles for tropical cyclone than all peril deductibles and are in place for a large portion of coastal insured properties.
 • Include coverage for flood-related losses for auto comprehensive damage coverage since we have additional catastrophe exposure, beyond the property lines, for auto customers who have purchased comprehensive damage coverage.
 • Offer a homeowners policy in 43 states. Allstate House and Home provides options of coverage for roof damage, including graduated coverage and pricing based on roof type and age. In 2023, premiums written totaled $6.84 billion or 54.3% of homeowners premiums written compared to $5.60 billion or 49.9% in 2022.
 Hurricanes We consider the greatest areas of potential catastrophe losses due to hurricanes to be major metropolitan centers in counties along the eastern and gulf coasts of the United States. The average premium on a property policy near these coasts is generally greater than in other areas. However, average premiums are often not considered commensurate with the inherent risk of loss. In addition, as explained in Note 15 of the consolidated financial statements, in various states Allstate is subject to assessments from assigned risk plans, reinsurance facilities and joint underwriting associations providing insurance for wind related property losses.

 We have addressed our risk of hurricane loss by, among other actions, purchasing reinsurance for specific states and on a countrywide basis for our personal lines property insurance in areas most exposed to hurricanes, limiting personal homeowners, landlord package policy and manufactured home new business writings in coastal areas in southern and eastern states, implementing tropical cyclone deductibles where appropriate, and not offering continuing coverage on certain policies in coastal counties in certain states. We continue to seek appropriate returns for the risks we write. This may require further actions, similar to those already taken, in geographies where we are not getting appropriate returns. However, we may maintain or opportunistically increase our presence in areas where adequate risk adjusted returns can be achieved.
 Earthquakes We do not offer earthquake coverage in most states. We retain approximately 25,000 PIF with earthquake coverage, with the largest number of policies located in Kentucky, due to regulatory and other reasons. We purchase reinsurance in Kentucky and enter into arrangements in many states to make earthquake coverage available through our brokerage platform.
 We continue to have exposure to earthquake risk on certain policies that do not specifically exclude coverage for earthquake losses, including our auto policies, and to fires following earthquakes. Allstate homeowner policyholders in California are offered coverage for damage caused by an earthquake through the California Earthquake Authority ("CEA"), a privately-financed, publicly-managed state agency created to provide insurance coverage for earthquake damage. Allstate is subject to assessments from the CEA under certain circumstances as explained in Note 15 of the consolidated financial statements. While North Light writes property policies in California, which can include earthquake coverage, this coverage is 100% ceded via quota share reinsurance.
 Fires following earthquakes Under a standard homeowners policy we cover fire losses, including those caused by an earthquake. Actions taken related to our risk of loss from fires following earthquakes include restrictive underwriting guidelines in California for new business writings, purchasing reinsurance for Kentucky personal lines property risks, and purchasing nationwide occurrence reinsurance, excluding Florida.
 Wildfires Actions taken related to managing our risk of loss from wildfires include purchasing nationwide occurrence reinsurance, new and renewal inspection programs to identify and remediate wildfire risk as well as leveraging contemporary underwriting tools in select areas. While these programs are designed to mitigate risk, the exposure to wildfires still exists. We continue to manage our exposure and seek appropriate returns for the risks we write.
 To manage the exposure, we may implement further actions, similar to those already taken, in geographies where we are not achieving appropriate returns. However, we may maintain or opportunistically

 increase our presence in areas where adequate risk adjusted returns can be achieved.
 Catastrophe reinsurance The total cost of our property catastrophe reinsurance programs, excluding reinstatement premiums, during 2023 was $1.02 billion compared to $788 million during 2022. Catastrophe placement premiums are a reduction of premium with approximately 74% related to homeowners. The increases were driven by higher Nationwide program

 costs. A description of our current catastrophe reinsurance program appears in Note 11 of the consolidated financial statements.
 Expense ratio decreased 2.0 points in 2023 compared to 2022, primarily due to higher earned premium growth relative to fixed costs and lower advertising costs, partially offset by higher restructuring costs.

 2023 Form 10-K Run-off Property-Liability

 Run-off Property-Liability Segment
 The Run-off Property-Liability segment includes results from property and casualty insurance coverage that primarily relates to policies written during the 1960s through the mid-1980s. Our exposure to asbestos, environmental and other run-off lines claims arises principally from direct excess commercial insurance, assumed reinsurance coverage, direct primary commercial insurance and other businesses in run-off. We may pursue settlement agreements including policy buybacks on direct excess commercial business when appropriate to improve the certainty of the liabilities. Settlement agreements are negotiated contracts between Allstate and third parties that generally set forth the rights and obligations of the parties, including terms of payment for claims. For additional information on our strategy and outlook, see Part I, Item 1. Business - Strategy and Segment Information.

 Underwriting losses in 2023 and 2022 primarily related to our annual reserve review using established industry and actuarial best practices. The annual review resulted in unfavorable reserve reestimates totaling $80 million and $118 million in 2023 and 2022, respectively. The reserve reestimates are included as part of claims and claims expense.
 The reserve reestimates in 2023 primarily related to new reported information and defense costs for asbestos and other run-off exposures and higher than expected environmental reported losses. The reserve reestimates in 2022 primarily related to new reported information and defense costs for asbestos and higher than expected reported losses for environmental and other run-off exposures.
 We believe that our reserves are appropriately established based on available facts, technology, laws, regulations, and assessments of other pertinent factors and characteristics of exposure (e.g., claim activity, potential liability, jurisdiction, products versus non-products exposure) presented by individual policyholders, assuming no change in the legal, legislative or economic environment. However, as we progress with the resolution of disputed claims in the courts and arbitrations and with negotiations and settlements, our reported losses may be more variable.

 Total gross payments were $124 million and $125 million for 2023 and 2022, respectively. Payments primarily related to settlement agreements reached with several insureds on large claims, mainly asbestos related losses, where the scope of coverages has been agreed upon. The claims associated with these settlement agreements are expected to be substantially paid out over the next several years as qualified claims are submitted by these insureds.

 Reinsurance collections were $35 million and $37 million for 2023 and 2022, respectively.

 Adjusted net income decreased 37.3% or $63 million in 2023 compared to 2022, due to an increase in state income taxes and deferred tax liabilities for Allstate Dealer Services, higher appliance and furniture claim severity at Allstate Protection Plans and lower third-party lead sales at Arity, partially offset by improved margins at Allstate Roadside and lower expenses at Allstate Identity Protection.
 Premiums written decreased 1.3% or $36 million in 2023 compared to 2022, primarily due to a decrease at Allstate Dealer Services and lower rescue volumes at

 Allstate Roadside, partially offset by international growth at Allstate Protection Plans.
 PIF increased 4.3% or 6 million in 2023 compared to 2022 due to an increase at Allstate Protection Plans.
 Other revenue decreased 8.1% or $28 million in 2023 compared to 2022, primarily due to reductions in third-party lead sales at Arity.
 Intersegment premiums and service fees decreased 7.4% to $138 million in 2023 compared to 2022, driven by decreased device sales for the

 2023 Form 10-K Property and Casualty Insurance Claims and Claims Expense Reserves

 Property and Casualty Insurance Claims and Claims Expense Reserves
 Underwriting results are significantly influenced by estimates of claims and claims expense reserves. For a description of our reserve process, see Note 9 of the consolidated financial statements. Further, for a description of our reserving policies and the potential variability in our reserve estimates, see the Application of Critical Accounting Estimates section of the MD&A. These reserves are an estimate of amounts necessary to settle all outstanding claims, including IBNR claims, as of the reporting date.

 The facts and circumstances leading to reestimates of reserves relate to changes in claim activity and revisions to the development factors used to predict how losses are likely to develop from the end of a reporting period until all claims have been paid. Reestimates occur when actual losses differ from those predicted by the estimated development factors used in prior reserve estimates.
 We believe the net loss reserves exposures are appropriately established based on available facts, laws and regulations.

 Unfavorable reserve reestimates in 2023 were primarily due to National General personal auto lines, homeowners and commercial lines.

 Unfavorable reserve reestimates for personal auto in 2022 were primarily from bodily injury and physical damage coverages. Increases in injury coverages reflected recent data and updated assumptions related to severity of third-party bodily injury claims,

 The Allstate Corporation 57

 2023 Form 10-K Property and Casualty Insurance Claims and Claims Expense Reserves

 increased claims with attorney representation, litigation costs, increased medical treatment utilization and higher medical inflation. Increases in physical damage reflected the ongoing inflationary factors and supply chain shortages impacting used vehicle and parts prices, labor rates and length of claim resolution. Delays in the receipt of claims, including third-party carrier claims also contributed to the adverse development of claims reported in prior years. Unfavorable reserve reestimates for commercial were primarily from auto injury coverages for both shared economy and traditional segments with a large portion of the traditional segment increase related to states where the Company will no longer be selling new business.

 We conduct an annual review in the third quarter of each year to evaluate and establish asbestos, environmental and other run-off reserves. Reserves are recorded in the reporting period in which they are determined. Using established industry and actuarial best practices and assuming no change in the regulatory or economic environment, this detailed and comprehensive methodology determines reserves based on assessments of the characteristics of exposure (e.g. claim activity, potential liability, jurisdiction, products versus non-products exposure) presented by policyholders.

 The survival ratio is calculated by taking our ending reserves divided by payments made during the year. This is a commonly used but simplistic and imprecise approach to measuring the adequacy of asbestos and environmental reserve levels. Many factors, such as mix of business, level of coverage provided and settlement procedures have significant impacts on the amount of environmental and asbestos claims and claims expense reserves, claim payments and the resultant ratio. As payments result in corresponding reserve reductions, survival ratios can be expected to vary over time. The asbestos and environmental net 3-year survival ratio in 2023 increased from 2022 due to lower average payments.

 Reinsurance and indemnification programs We utilize reinsurance to reduce exposure to catastrophe risk and manage capital, and to support the required statutory surplus and the insurance financial strength ratings of certain subsidiaries such as Castle Key Insurance Company ("CKIC") and Allstate New Jersey Insurance Company ("ANJ"). We purchase significant reinsurance to manage our aggregate countrywide exposure to an acceptable level. The price and terms of reinsurance and the credit quality of the reinsurer are considered in the purchase process. We have also purchased reinsurance to mitigate exposures in our long-tail liability lines, including environmental, asbestos and other run-off lines as well as our commercial lines, including shared economy. We also participate in various indemnification mechanisms,

 including state-based industry pool or facility programs mandating participation by insurers offering certain coverage in their state and the federal government National Flood Insurance Program ("NFIP"). See Note 11 of the consolidated financial statements for additional details on these programs.
 Intercompany reinsurance We enter into certain intercompany insurance and reinsurance transactions in order to maintain underwriting control and manage insurance risk among various legal entities. These reinsurance agreements have been approved by the appropriate regulatory authorities. All significant intercompany transactions have been eliminated in consolidation.
 Catastrophe reinsurance We anticipate completing the placement of our 2024 nationwide catastrophe reinsurance program in the first half of 2024. For further details of the existing 2023 program, see Note 11 of the consolidated financial statements.

 (1)N/A reflects no S&P Global Ratings ("S&P") or A.M. Best ratings available.
 (2)As of December 31, 2023 and 2022, MCCA includes $62 million of reinsurance recoverable on paid claims and $6.36 billion and $6.66 billion of reinsurance recoverable on unpaid claims, respectively.
 (3)Other reinsurance recoverables primarily relate to commercial lines, including shared economy, as well as asbestos, environmental and other liability exposures.
 Reinsurance and indemnification recoverables include an estimate of the amount of insurance claims and claims expense reserves that are ceded under the terms of the agreements, including IBNR unpaid losses. We calculate our ceded reinsurance and indemnification estimates based on the terms of each applicable agreement, including an estimate of how IBNR losses will ultimately be ceded under the agreement. We also consider other limitations and coverage exclusions under our agreements. Accordingly, our estimate of recoverables is subject to similar risks and uncertainties as our estimate of reserves for claims and claims expense. We believe the recoverables are appropriately established; however, as our underlying reserves continue to develop, the amount ultimately recoverable may vary from amounts currently recorded. We regularly evaluate the reinsurers and the respective amounts of our reinsurance recoverables, and a provision for uncollectible reinsurance recoverables is recorded, if needed. The establishment of reinsurance recoverables and the related allowance for

 uncollectible reinsurance is also an inherently uncertain process involving estimates. Changes in estimates could result in additional changes to the Consolidated Statements of Operations.
 Indemnification recoverables are considered collectible based on the industry pool and facility enabling legislation and the Company has not had any credit losses related to these programs and we do not anticipate losses in the foreseeable future. We also have not experienced credit losses on our catastrophe reinsurance programs, which include highly rated reinsurers.
 The allowance for uncollectible reinsurance relates to other reinsurance programs primarily related to our Run-off Property-Liability segment. The allowance was $62 million as of December 31, 2023 and 2022.
 The allowance is based upon our ongoing review of amounts outstanding, length of collection periods, changes in reinsurer credit standing, and other relevant factors. In addition, in the ordinary course of

 60 www.allstate.com

 2023 Form 10-K Property and Casualty Insurance Claims and Claims Expense Reserves

 business, we may become involved in coverage disputes with certain of our reinsurers that may ultimately result in lawsuits and arbitrations brought by or against such reinsurers to determine the parties' rights and obligations under the various reinsurance agreements. We employ dedicated specialists to manage reinsurance collections and disputes. We also consider recent developments in commutation activity between reinsurers and cedents, and recent trends in arbitration and litigation outcomes in disputes between cedents and reinsurers in seeking to maximize our reinsurance recoveries.
 Adverse developments in the insurance industry have led to a decline in the financial strength of some of our reinsurance carriers, causing amounts

 recoverable from them and future claims ceded to them to be considered a higher risk. There has also been consolidation activity in the industry, which causes reinsurance risk across the industry to be concentrated among fewer companies.
 See Note 2 of the consolidated financial statements for a description of the methodology utilized to calculate the allowance for reinsurance recoverables.
 For further details related to our reinsurance and indemnification recoverables, see the Regulation section in Part I and Note 11 of the consolidated financial statements.

 In 2023, ceded premiums earned increased primarily due to catastrophe reinsurance. In 2022, ceded premiums earned decreased primarily due to the expiration of legacy National General reinsurance programs.
 In 2023, ceded claims and claims expenses decreased $967 million primarily due to lower amounts related to NFIP, and a reduction in gross reserves for

 Michigan personal injury protection coverage. In 2022, ceded claims and claims expenses decreased $1.88 billion primarily due to higher gross catastrophe losses in 2021 that resulted in reinsurance activity. For further discussion of these items, see Regulation, Indemnification Programs and Note 11 of the consolidated financial statements.

 (2)Gross reserves for the year ended December 31, 2023, comprise 77% case reserves and 23% IBNR. Gross reserves for the year ended December 31, 2022, comprise 76% case reserves and 24% IBNR. Gross reserves for the year ended December 31, 2021, comprise 74% case reserves and 26% IBNR. The MCCA does not require member companies to report ultimate case reserves.
 Pending MCCA claims differ from most personal lines insurance pending claims as other personal lines policies incurred claims settle in shorter periods due to having a coverage limit. MCCA claims can be outstanding for a claimant's lifetime, as there is no contractual limitation. Many of these injuries are catastrophic in nature, resulting in serious permanent disabilities that require attendant and residential care for periods that may span decades. A significant portion of the ultimate incurred claim reserves and the recoverables can be attributed to a small number of catastrophic claims that occurred more than five years ago and continue to pay lifetime benefits.

 As of December 31, 2023, approximately 1,350 of our catastrophic claims that are eligible for reimbursement are pending with the MCCA, of which approximately 80% represents claims that occurred more than 5 years ago. There are 74 claims with reserves in excess of $15 million as of December 31, 2023, which comprise approximately 30% of the gross ending reserves in the table above. As a result, significant developments with a single claimant can result in volatility in prior year incurred claims.

 New annualized premium sales (annualized premiums at initial employer voluntary benefits customer enrollment or health policy sale) decreased by $2 million to $732 million in 2023. The decrease in 2023 primarily relates to a decline in employer voluntary benefits, partially offset by growth in group health and individual health businesses.
 Other revenue increased $45 million in 2023 compared to 2022, primarily due to an increase in group health administrative fees.
 Accident, health and other policy benefits increased 2.8% or $29 million in 2023 compared to 2022, primarily due to growth in group health, partially offset by lower benefit utilization in individual health.
 Accident, health and other policy benefits include changes in the reserve for future policy benefits,

 expected development on reported claims, and reserves for incurred but not reported claims as shown in Note 10 of the consolidated financial statements.
 Benefit ratio increased 1.1 points to 56.2 in 2023 compared to 55.1 in 2022, primarily due to higher benefit utilization in employer voluntary benefits and group health, partially offset by lower benefit utilization in individual health.
 Amortization of DAC increased 10.3% or $14 million in 2023 compared to 2022, primarily due to higher amortization related to growth in individual health. For information on changes in DAC, see Note 12 of the consolidated financial statements.

 Overview and strategy
 The return on our investment portfolios is an important component of our ability to offer good value to customers, fund business improvements and create value for shareholders. Investment portfolios are held for Property-Liability, Protection Services, Allstate Health and Benefits and Corporate and Other operations. While taking into consideration the investment portfolio in aggregate, management of the underlying portfolios is significantly influenced by the nature of each respective business and its corresponding liability profile. For each business, we identify a strategic asset allocation which considers both the nature of the liabilities and the risk and return characteristics of the various asset classes in which we invest. This allocation is informed by our long-term business and market expectations, as well as other considerations such as risk appetite, portfolio diversification, duration, desired liquidity and capital. Within appropriate ranges relative to strategic allocations, tactical allocations are made in consideration of prevailing and potential future market conditions. We manage risks that involve uncertainty related to interest rates, inflation, credit spreads, equity returns and currency exchange rates.
 The Property-Liability portfolio emphasizes protection of principal and consistent income generation, within a total return framework. This approach has produced competitive returns over the long term and is designed to ensure financial strength and stability for paying claims, while maximizing economic value and surplus growth. Products with lower liquidity needs, such as auto insurance and run-off lines, and capital create capacity to invest in less liquid higher yielding fixed income securities, performance-based investments such as limited partnerships and equity securities. Products with higher liquidity needs, such as homeowners insurance, are invested primarily in high quality liquid fixed income securities.
 The Protection Services portfolio is focused on protection of principal and consistent income generation, within a total return framework. The portfolio is largely comprised of fixed income securities with a lesser allocation to equity securities and short-term investments.
 The Allstate Health and Benefits portfolio is focused on protection of principal and consistent income generation while targeting an appropriate return on capital. The portfolio is largely comprised of fixed income securities with a small allocation to commercial mortgage loans and equity securities.
 The Corporate and Other portfolio is focused on liquidity needs and capital preservation within a total return framework. The portfolio is largely comprised of high-quality liquid fixed income securities and short-term investments.

 We utilize two primary strategies to manage risks and returns and to position our portfolio to take advantage of market opportunities while attempting to mitigate adverse effects. As strategies and market conditions evolve, the asset allocation may change.
 Market-based strategy seeks to deliver predictable earnings aligned to business needs and provide flexibility to adjust investment risk profile based on enterprise objectives and market opportunities primarily through public and private fixed income investments and public equity securities.
 Performance-based strategy seeks to deliver attractive risk-adjusted returns and supplement market risk with idiosyncratic risk. Returns are impacted by a variety of factors including general macroeconomic and public market conditions as public benchmarks are often used in the valuation of underlying investments. Variability in earnings will also result from the performance of the underlying assets or business and the timing of sales of those investments. Earnings from the sales of investments may be recorded as net investment income or net gains and losses on investments and derivatives. The portfolio, which primarily includes private equity (including infrastructure investments) and real estate with a majority being limited partnerships, is diversified across a number of characteristics, including managers or partners, vintage years, investment strategies, geographies (including international) and industry sectors or property types. These investments are generally illiquid in nature, often require specialized expertise, typically involve a third-party manager, and enhance returns and income through transformation at the company or property level. A portion of these investments seek returns in markets or asset classes that are dislocated or special situations, primarily in private markets.
 Investments in the Middle East As of December 31, 2023, we have approximately $47 million investment exposure in the Middle East, of which approximately $43 million is held in Israel, which is primarily indirect exposure through funds managed by external asset managers.
 Investments in Russia and Ukraine As of December 31, 2023, we do not have any direct or indirect investments in Russia, Belarus or Ukraine.

 The Allstate Corporation 65

 Investments Outlook
 We plan to focus on the following priorities:
 • Enhance investment portfolio returns through use of a dynamic capital allocation framework and focus on tax efficiency.
 • Leverage our broad capabilities to manage the portfolio to earn higher risk-adjusted returns on capital.
 • Invest for the specific needs and characteristics of Allstate's businesses, including its corresponding liability profile.
 We utilize our integrated enterprise risk and return management framework to determine the amount of investment risk we are willing to accept. After reducing interest rate risk by shortening the portfolio duration beginning in late 2021, during 2023 we extended the fixed income portfolio duration as the sustained higher

 market yields provide an opportunity to increase risk-adjusted returns. As recession risks remain elevated, we also retained defensive positioning to equity risk and credit risk in the portfolio through a reduced allocation to public equity, high yield bonds and bank loans. We expect to maintain performance-based investments in our portfolio, consistent with our strategy to have a greater proportion of return derived from idiosyncratic assets or operating performance.

 During 2023, strategic actions focused on optimizing portfolio yield, return and risk in the more volatile and rising interest rate environment. The sustained higher market yields provide an opportunity to increase risk-adjusted returns, so we extended the fixed income portfolio duration to 4.8 years (including the effect of interest rate derivatives and any call

 features associated with the securities) during 2023 from 3.4 years as of December 31, 2022. Considering the ongoing risk of recession, we retained a lower allocation to high-yield bonds, bank loans and public equity relative to year-end 2022. We maintained performance-based investments in the Property-Liability portfolio.

 Fixed income securities are rated by third-party credit rating agencies or are internally rated. The Securities Valuation Office ("SVO") of the National Association of Insurance Commissioners ("NAIC") evaluates the fixed income securities of insurers for regulatory reporting and capital assessment purposes. The NAIC assigns securities to one of six credit quality categories defined as "NAIC designations". In general, securities with NAIC designations of 1 and 2 are considered investment grade and securities with NAIC designations of 3 through 6 are considered below investment grade. The rating is either received from the SVO based on availability of applicable ratings from rating agencies on the NAIC Nationally Recognized Statistical Rating Organizations provider list, including Moody's Investors Service ("Moody's"), S&P Global Ratings ("S&P"), Fitch Ratings ("Fitch"), or a comparable internal rating.
 As a result of time lags between the funding of investments, the finalization of legal documents, and the completion of the SVO filing process, the portfolio includes certain securities that have not yet been designated by the SVO as of each balance sheet date

 and the categorization of these securities is based on the expected ratings indicated by internal analysis.
 As of December 31, 2023, 91.5% of the consolidated fixed income securities portfolio was rated investment grade. Credit ratings below these designations are considered lower credit quality or below investment grade, which includes high yield bonds.
 Market prices for certain securities may have credit spreads which imply higher or lower credit quality than the current third-party rating. Our initial investment decisions and ongoing monitoring procedures for fixed income securities are based on a due diligence process which includes, but is not limited to, an assessment of the credit quality, sector, structure and liquidity risks of each issuer.
 Fixed income portfolio monitoring is a comprehensive process to identify and evaluate each fixed income security that may require a credit loss allowance. The process includes a quarterly review of all securities to identify instances where the fair value of a security compared to its amortized cost is below internally established thresholds.

 Municipal bonds, including tax exempt and taxable securities, include general obligations of state and local issuers and revenue bonds.
 Our practice for acquiring and monitoring municipal bonds is predominantly based on the underlying credit quality of the primary obligor. We currently rely on the primary obligor to pay all contractual cash flows and are not relying on bond insurers for payments. As a result of downgrades in the insurers' credit ratings, the ratings of the insured municipal bonds generally reflect the underlying ratings of the primary obligor.
 Corporate bonds include publicly traded and privately placed securities. Privately placed securities primarily consist of corporate issued senior debt securities that are negotiated with the borrower or are issued by entities in unregistered form under SEC Rule 144A which allows purchasers to more easily resell these securities under certain conditions.
 Our $7.91 billion portfolio of privately placed securities, primarily 144A bonds, is diversified by issuer, industry sector and country. The portfolio is made up of 455 issuers. Privately placed corporate obligations may contain structural security features such as financial covenants and call protections that provide investors greater protection against credit deterioration, reinvestment risk or fluctuations in interest rates than those typically found in publicly registered debt

 securities. Additionally, investments in these securities are made after fundamental analysis of issuers and sectors along with macro and asset class views. Ongoing monitoring includes continuous assessment of operating performance and financial position. Every issue not rated by an independent rating agency is internally rated with a formal rating affirmation at least once a year. Liquidity of securities issued by public entities in unregistered form is similar to public debt markets.
 Our corporate bond portfolio includes $4.11 billion of below investment grade bonds, $3.39 billion of which are privately placed, primarily 144A bonds. These securities are diversified by issuer and industry sector. The below investment grade corporate bonds portfolio is made up of 317 issuers. We employ fundamental analyses of issuers and sectors along with macro and asset class views to identify investment opportunities. This results in a portfolio with broad exposure to the high yield market with an emphasis on idiosyncratic positions reflective of our views of market conditions and opportunities.
 Foreign government securities consist of Canadian governmental and provincial securities (all of which are held by our Canadian companies).

 ABS are structured securities that are primarily collateralized by consumer or corporate borrowings and residential and commercial real estate loans. The cash flows from the underlying collateral paid to the securitization trust are generally applied in a pre-determined order and are designed so that each security issued by the trust, typically referred to as a "class", qualifies for a specific original rating.
 ABS includes collateralized debt obligations, consumer and other ABS. Credit risk is managed by monitoring the performance of the underlying collateral. Many of the securities in the ABS portfolio have credit enhancement with features such as overcollateralization, subordinated structures, reserve funds, guarantees or insurance. ABS also includes residential mortgage-backed securities and commercial mortgage-backed securities.
 For example, the "senior" portion or "top" of the capital structure, or rating class, which would originally qualify for a rating of Aaa typically has priority in receiving principal repayments on the underlying collateral and retains this priority until the class is paid in full. In a sequential structure, underlying collateral principal repayments are directed to the most senior rated Aaa class in the structure until paid in full, after which principal repayments are directed to the next most senior Aaa class in the structure until it is paid in full. Senior Aaa classes generally share any losses from the underlying collateral on a pro-rata basis after losses are absorbed by classes with lower original ratings.
 The payment priority and class subordination included in these securities serves as credit enhancement for holders of the senior or top portions of the structures. These securities continue to retain the payment priority features that existed at the origination of the securitization trust. Other forms of credit enhancement may include structural features embedded in the securitization trust, such as overcollateralization, excess spread and bond insurance. The underlying collateral may contain fixed interest rates, variable interest rates (such as adjustable rate mortgages), or both fixed and variable rate features.
 Equity securities of $2.41 billion primarily include common stocks, exchange traded and mutual funds, non-redeemable preferred stocks and real estate investment trust ("REIT") equity investments. Certain exchange traded and mutual funds have fixed income securities as their underlying investments.
 Mortgage loans of $822 million mainly comprise loans secured by first mortgages on developed commercial real estate. Key considerations used to manage our

 exposure include property type and geographic diversification. For further detail on our mortgage loan portfolio, see Note 5 of the consolidated financial statements.
 Limited partnership interests include $7.15 billion of interests in private equity funds, $1.09 billion of interests in real estate funds and $141 million of interests in other funds as of December 31, 2023. We have commitments to invest additional amounts in limited partnership interests totaling $2.94 billion as of December 31, 2023.

 In general, the gross unrealized losses are related to an increase in market yields, which may include increased risk-free interest rates and wider credit spreads since the time of initial purchase. Similarly, gross unrealized gains reflect a decrease in market yields since the time of initial purchase.

 Performance-based investment income decreased 51.3% or $525 million in 2023 compared to 2022, primarily due to lower valuation increases compared to the prior year and lower income from the sales of underlying investments.

 Performance-based investment results and income can vary significantly between periods and are influenced by economic conditions, equity market performance, comparable public company earnings multiples, capitalization rates, operating performance of the underlying investments and the timing of asset sales. The company typically employs a lag in recording and recognizing changes in valuations of limited partnership interests due to the availability of investee financial statements.

Net losses on investments and derivatives in 2022 related primarily to decreased valuation on equity investments and losses on sales of fixed income securities, partially offset by increased valuation change and settlements of derivatives.
 Net losses on sales in 2023 and 2022 related primarily to sales of fixed income securities in connection with ongoing portfolio management.

 Net losses on valuation change and settlements of derivatives of $84 million in 2023 primarily related to net losses on equity futures used to manage equity exposure, losses on credit default swaps used to reduce credit risk and losses on foreign currency contracts used to manage foreign currency risk. Net gains in 2022 primarily comprised of gains on interest rate futures used to mitigate the impact of increases in interest rates, gains on foreign currency contracts due to the strengthening of the U.S. dollar and gains on equity futures used to manage exposure to equity markets.

 2023 Form 10-K Market Risk

 Market Risk
 Market risk is the risk that we will incur losses due to adverse changes in interest rates, credit spreads, equity prices, commodity prices or foreign currency exchange rates. Adverse changes to these rates and prices may occur due to changes in fiscal policy, inflation, the economic climate, the liquidity of a market or market segment, insolvency or financial distress of key market makers or participants or changes in market perceptions of credit worthiness or risk tolerance. Our primary market risk exposures are to changes in interest rates, credit spreads and equity prices, and to a lesser extent, foreign currency exchange rates. We also have direct and indirect exposure to commodity price changes through our diversified investments in agriculture, infrastructure and energy primarily held in limited partnership interests and consolidated subsidiaries.
 The active management of market risk is integral to our results of operations. We may use the following approaches to manage exposure to market risk within defined tolerance ranges:
 1)Rebalance existing asset or liability portfolios
 2)Change the type of investments purchased in the future
 3)Use derivative instruments to modify the market risk characteristics of existing assets and liabilities or assets expected to be purchased
 Overview In formulating and implementing guidelines for investing funds, we seek to earn attractive risk-adjusted returns that enhance our ability to offer competitive prices to customers while contributing to stable profits and long-term capital growth. Accordingly, our investment decisions and objectives are informed by underlying risks. Investment policies define the overall framework for managing market and other investment risks, including accountability and controls over risk management activities. Subsidiaries that conduct investment activities follow policies that have been approved by their respective boards of directors and which specify the investment limits and strategies that are appropriate given the liquidity, surplus, product profile and regulatory requirements of the subsidiary. Executive oversight of investment activities is conducted primarily through the subsidiaries' boards of directors and legal entity investment committees. The Enterprise Risk and Return Council ("ERRC") oversees the aggregate risk of Allstate and its subsidiaries. Working in conjunction with the board or the investment committee of each subsidiary, as applicable, the ERRC evaluates the risk tolerance of each subsidiary and determines the aggregate risk tolerance of the enterprise.

 We use widely-accepted quantitative and qualitative approaches to measure, monitor and manage market risk. We evaluate our market risk exposure using multiple measures including but not limited to:

 • Duration, a measure of the price sensitivity of assets and liabilities to changes in interest rates

 • Value-at-risk, a statistical estimate that the change in fair value of a portfolio will exceed a certain amount over a given time horizon, at a specified probability

 • Scenario analysis, an estimate of the potential changes in the fair value of a portfolio that could occur under hypothetical market conditions defined by changes to multiple market risk factors: interest rates, credit spreads, equity prices or currency exchange rates

 • Sensitivity analysis, an estimate of the potential changes in the fair value of a portfolio that could occur using hypothetical shocks to a market risk factor

 The selection of measures used in our sensitivity analysis should not be construed as our prediction of future market events, but only as an illustration of the potential effect of such an event

 In general, we establish investment portfolio asset allocation and market risk limits based upon a combination of these measures. The asset allocation limits place restrictions on the total funds that may be invested within an asset class. Comprehensive day-to-day management of market risk within defined tolerance ranges occurs as portfolio managers buy and sell within their respective markets based upon the acceptable boundaries established by investment policies. Although we apply a similar overall philosophy to market risk, the underlying business frameworks and the accounting and regulatory environments may differ between our products and therefore affect investment decisions and risk parameters. Our actual experience may differ from the results of the sensitivity measurements provided below.
 Interest rate risk is the risk that we will incur a loss due to adverse changes in risk-free interest rates. This risk arises from many of our primary activities, as we invest substantial funds in interest-sensitive assets. Changes in interest rates can have favorable and unfavorable effects on our results. For example, increases in rates can improve investment income, but decrease the fair value of our fixed income securities portfolio which may result in sales of assets at losses. Decreases in rates could increase the fair value of our fixed income securities portfolio while decreasing future investment income due to reinvestment at lower market yields and accelerated pay-downs and prepayments of certain investments.

 74 www.allstate.com

 2023 Form 10-K Market Risk

 For our issued debt, we monitor market interest rates and evaluate refinancing opportunities as maturity dates approach. To mitigate this risk, we ladder the maturity dates of our debt. For our issued noncumulative perpetual preferred stock, we monitor market dividend rates and evaluate opportunities to redeem or refinance on or after specified dates. For further detail regarding our debt and our preferred stock, see Note 13 of the consolidated financial statements and the Capital Resources and Liquidity section of this Item.
 Our assessment of interest rate risk reflects the effect of changing risk-free interest rates on interest-sensitive assets, including investments with callable or prepayable features. As of December 31, 2023, the fixed income portfolio duration(1) was 4.8 compared to 3.4 as of December 31, 2022.

 To the extent that conditions differ from the assumptions we used in these calculations, duration and rate shock measures could be significantly impacted. These calculations may not fully capture the effect of non-parallel changes in the term structure of interest rates or large changes in interest rates.
 Credit spread risk is the risk that we will incur a loss due to adverse changes in credit spreads ("spreads"). A credit spread is the additional yield on fixed income securities and loans above the risk-free rate that market participants require to compensate them for assuming credit, liquidity or prepayment risks. This risk arises from many of our primary activities, as we invest substantial funds in spread-sensitive fixed income assets. We assess credit spread risk by evaluating spread duration which measures the price sensitivity of the assets to changes in spreads.
 As of December 31, 2023, the spread duration(1) was 4.7 compared to 4.0 as of December 31, 2022.

 Equity investments(1) As of December 31, 2023, we held $1.52 billion in equity investments that comprise equity securities, excluding those with fixed income securities as their underlying investments, and including limited partnership interests where the underlying assets are predominately public equity securities, compared to $4.06 billion as of December 31, 2022.

 2023 Form 10-K Market Risk

 Foreign currency exchange rate risk is the risk that we will incur economic losses due to adverse changes in foreign currency exchange rates. This risk primarily arises from our foreign equity investments, including common stocks, limited partnership interests, and our Canada, Northern Ireland, Europe and India operations. We use foreign currency derivative contracts to partially offset this risk.

 As of December 31, 2023, we had $3.56 billion in foreign currency denominated investments, including the effects of foreign currency derivative contracts, and $1.25 billion net investment in our foreign subsidiaries, primarily related to our Canada operations. These amounts were $3.10 billion and $1.14 billion, respectively, as of December 31, 2022.

 Allstate shareholders' equity increased in 2023, primarily due to lower unrealized net capital losses on investments, partially offset by dividends paid to shareholders, common share repurchases and a net loss. In 2023, we paid dividends of $925 million and $107 million related to our common and preferred shares, respectively. Allstate shareholders' equity decreased in 2022, primarily due to net unrealized capital losses on investments in 2022 compared to gains in 2021, common share repurchases, a net loss and dividends paid to shareholders. In 2022, we paid dividends of $926 million and $105 million related to our common and preferred shares, respectively.
 Repayment of debt On March 29, 2023, the Company repaid, at maturity, $250 million of Floating Rate Senior Notes that bear interest at a floating rate equal to three-month London Interbank Offered Rate ("LIBOR") plus 0.63% per year. On June 15, 2023, the Company repaid, at maturity, $500 million of 3.15% Senior Notes.
 Issuance of debt On March 31, 2023, the Company issued $750 million of 5.25% Senior Notes due 2033. Interest on the Senior Notes is payable semi-annually in arrears on March 30 and September 30 of each year, beginning on September 30, 2023. The Senior Notes are redeemable at any time at the applicable redemption price prior to the maturity date. The net proceeds of this issuance were used to repay the $500 million senior debt maturity and for general corporate purposes.
 Redemption of preferred stock On April 17, 2023, the Company redeemed all 23,000 shares of Fixed Rate Noncumulative Preferred Stock, Series G, par value $1.00 per share and liquidation preference $25,000 per share, and the corresponding depositary shares for a total redemption payment of $575 million. The Company recognized $18 million of original issuance costs in preferred stock dividends on the Consolidated Statements of Operations and Consolidated Statements of Shareholders' Equity.
 Issuance of preferred stock On May 18, 2023, the Company issued 24,000 shares of Fixed Rate Noncumulative Preferred Stock, Series J, par value

 $1.00 per share and liquidation preference amount of $25,000 per share, and the corresponding depositary shares for gross proceeds of $600 million. The preferred stock is perpetual and has no maturity date. The preferred stock is redeemable at the Company's option in whole or in part, on or after July 15, 2028 at a redemption price of $25,000 per share, plus declared and unpaid dividends. Prior to July 15, 2028, the preferred stock is redeemable at the Company's option, in whole but not in part, within 90 days of the occurrence of certain rating agency events at a redemption price equal to $25,500 per share, plus declared and unpaid dividends, or in whole but not in part, within 90 days after the occurrence of a regulatory capital event, at a redemption price equal to $25,000 per share, plus declared and unpaid dividends.
 Common share repurchases In July 2023, we suspended repurchasing shares under the current authorization. As of December 31, 2023, there was $472 million remaining of the $5.00 billion program. The authorization for the share repurchase program expires on March 31, 2024.
 During 2023, we repurchased 2.8 million common shares, or 1.1% of total common shares outstanding as of December 31, 2022, for $330 million.
 Since 1995, we have acquired 792 million shares of our common stock at a cost of $43.18 billion, primarily as part of various stock repurchase programs. We have reissued 156 million common shares since 1995, primarily associated with our equity incentive plans, the 1999 acquisition of American Heritage Life Investment Corporation and the 2001 redemption of certain mandatorily redeemable preferred securities. Since 1995, total common shares outstanding has decreased by 636 million shares or 70.8%, primarily due to our repurchase programs.
 Common shareholder dividends On January 3, 2023, April 3, 2023, July 3, 2023 and October 2, 2023, we paid a common shareholder dividend of $0.85, $0.89, $0.89 and $0.89, respectively. On November 15, 2023, we declared a common shareholder dividend of $0.89 payable on January 2, 2024.

 Our ratings are influenced by many factors including our operating and financial performance, asset quality, liquidity, overall portfolio mix, financial leverage (i.e., debt), exposure to risks such as catastrophes and the current level of operating leverage. The preferred stock and subordinated debentures are viewed as having a common equity component by certain rating agencies and are given equity credit up to a pre-determined limit in our capital structure as determined by their respective methodologies. These respective methodologies consider the existence of certain terms and features in the instruments such as the noncumulative dividend feature in the preferred stock.
 The Allstate Corporation (the "Corporation") and Allstate Insurance Company ("AIC") In March 2023, Moody's affirmed The Allstate Corporation's (the "Corporation") senior debt and short-term issuer ratings of A3 and P-2, respectively, and AIC's insurance financial strength rating of Aa3. The outlook for the ratings was changed from stable to negative.
 In August 2023, A.M. Best downgraded the Corporation's senior debt and short-term issuer ratings to a- and AMB-1, respectively, and affirmed AIC's insurance financial strength rating of A+. The outlook for the ratings is stable.
 In August 2023, S&P downgraded the Corporation's senior debt rating to BBB+ and affirmed the short-term issuer rating of A-2, and downgraded AIC's insurance financial strength rating to A+. The outlook for the ratings changed from negative to stable.
 American Heritage Life ("AHL") In August 2023, A.M. Best affirmed the insurance financial strength rating of A+ for AHL. The outlook for the rating is stable.
 Other property and casualty companies We have distinct and separately capitalized groups of subsidiaries licensed to sell property and casualty insurance that maintain separate group ratings. The ratings of these groups are influenced by the risks that relate specifically to each group. Many mortgage companies require property owners to have insurance from an insurance carrier with a secure financial strength rating from an accredited rating agency.
 In August 2023, A.M. Best affirmed the insurance financial strength rating of A of the members of Allstate New Jersey Group (Allstate New Jersey Insurance Company, Allstate New Jersey Property and Casualty Insurance Company, Encompass Insurance Company of New Jersey, Encompass Property and

 Casualty Insurance Company of New Jersey, Esurance Insurance Company of New Jersey). The outlook for the rating changed from stable to negative. ANJ writes auto and homeowners insurance in New Jersey. Allstate New Jersey Insurance Company also has a financial strength rating of A" from Demotech, which was affirmed in December 2023.
 In August 2023, A.M. Best affirmed the insurance financial strength rating of A+ for North Light, our excess and surplus lines carrier. The outlook for the North Light rating is stable.
 In August 2023, A.M. Best downgraded the insurance financial strength ratings of the members of Castle Key Group (Castle Key Insurance Company, Castle Key Indemnity Company, Encompass Floridian Insurance Company, Encompass Floridian Indemnity Company) to B. The outlook for the ratings changed from negative to stable. CKIC also has a financial strength rating of A' from Demotech that was affirmed in December 2023.
 ANJ and North Light do not have support agreements with AIC.
 Allstate's domestic property and casualty and life insurance subsidiaries prepare their statutory-basis financial statements in conformity with accounting practices prescribed or permitted by the insurance department of the applicable state of domicile. Statutory surplus is a measure that is often used as a basis for determining dividend paying capacity, operating leverage and premium growth capacity, and it is also reviewed by rating agencies in determining their ratings.
 The property and casualty business is comprised of 59 insurance companies as of December 31, 2023, each of which has individual company dividend limitations. As of December 31, 2023, total statutory surplus is $14.56 billion compared to $15.28 billion as of December 31, 2022. Property and casualty subsidiaries surplus was $14.25 billion as of December 31, 2023, compared to $15.00 billion as of December 31, 2022. Life, accident and health insurance subsidiaries surplus was $310 million as of December 31, 2023, compared to $279 million as of December 31, 2022.
 The NAIC has developed financial relationships or tests known as the Insurance Regulatory Information System to assist state insurance regulators in monitoring the financial condition of insurance companies and identifying companies that require special attention or actions by state insurance regulators. The NAIC analyzes financial data provided by insurance companies using prescribed ratios, each

 78 www.allstate.com

 with defined "usual ranges". Additional regulatory scrutiny may occur if a company's ratios fall outside the usual ranges for four or more of the ratios. Nine of our domestic insurance companies have four or more

 ratios outside the usual ranges due to higher written premiums and net losses in 2023.

 Contractual obligations and commitments We have short-term and long-term contractual obligations and commitments. We manage our short-term liquidity position to ensure the availability of a sufficient amount of liquid assets to extinguish short-term liabilities as they come due in the normal course of business, including utilizing potential sources of liquidity. Long-term obligations include known

 contractual commitments that require cash needs beyond 12 months.
 Short-term contractual obligations are typically settled with cash or short-term investments and operating cash flows. Most of these obligations are paid within one year. These include unconditional purchase obligations, other liabilities and accrued expenses, including liabilities for collateral and operating leases, and net unrecognized tax benefits.

 The Allstate Corporation 79

 We actively manage our financial position and liquidity levels in light of changing market, economic, and business conditions. Liquidity is managed at both the entity and enterprise level across the Company and is assessed on both base and stressed level liquidity needs. We believe we have sufficient liquidity to meet these needs. Additionally, we have existing intercompany agreements in place that facilitate liquidity management across the Company to enhance flexibility.
 As of December 31, 2023, we held $16.20 billion of cash, U.S. government and agencies fixed income securities, public equity securities and short-term investments, which we would expect to be able to liquidate within one week. In addition, we regularly estimate how much of the total portfolio, which includes high quality corporate fixed income and municipal holdings, can be reasonably liquidated within one quarter. These estimates are subject to considerable uncertainty associated with evolving market conditions. As of December 31, 2023, cash and estimated liquidity available within one quarter, under normal market conditions and at current market prices, was $23.52 billion.
 Certain remote events and circumstances could constrain our liquidity. Those events and circumstances include, for example, a catastrophe resulting in extraordinary losses, a decrease in market liquidity, dramatic changes in security pricing, a cybersecurity breach, a downgrade in our senior long-term debt ratings to non-investment grade status, or a downgrade in AIC's financial strength ratings. The rating agencies also consider the interdependence of our individually rated entities; therefore, a rating change in one entity could potentially affect the ratings of other related entities.
 The Corporation is party to an Amended and Restated Intercompany Liquidity Agreement ("Liquidity Agreement") with certain subsidiaries, which includes, but is not limited to AIC. The Liquidity Agreement allows for short-term advances of funds to be made between parties for liquidity and other general corporate purposes. The Liquidity Agreement does not establish a commitment to advance funds on the part of any party. AIC serves as a lender and borrower, certain other subsidiaries serve only as borrowers, and the Corporation serves only as a lender. The maximum amount of potential funding under each of these agreements is $1.00 billion.
 In addition to the Liquidity Agreement, the Corporation also has an intercompany loan agreement with certain of its subsidiaries, which includes, but is not limited to, AIC. The amount of intercompany loans available to the Corporation's subsidiaries is at the discretion of the Corporation. The maximum amount of loans the Corporation will have outstanding to all its eligible subsidiaries at any given point in time is limited to $1.00 billion. The Corporation may use commercial paper borrowings, bank lines of credit and securities lending to fund intercompany borrowings.

 Parent company capital capacity At the parent holding company level, we have deployable assets totaling $3.41 billion as of December 31, 2023, primarily comprised of cash and short-term, fixed income and equity securities that are generally saleable within one quarter. The earnings capacity of the operating subsidiaries is the primary source of capital generation for the Corporation.
 The payment of dividends by AIC to The Allstate Corporation is limited by Illinois insurance law to formula amounts based on statutory net income and statutory surplus, as well as the timing and amount of dividends paid in the preceding twelve months. The maximum amount of dividends that AIC will be able to pay, without prior Illinois Department of Insurance approval, at a given point in time in 2024, based on 10% of actual 2023 statutory surplus, is estimated at $1.20 billion, less dividends paid during the preceding twelve months measured at that point in time. For the year ended December 31, 2023, the maximum amount of dividends allowed to be paid by AIC was $1.22 billion. No dividends were paid in 2023. Notification and approval of intercompany lending activities are also required by the Illinois Department of Insurance for those transactions that exceed formula amounts based on statutory admitted assets and statutory surplus.
 These holding company assets and subsidiary dividends provide funds for the parent company's fixed charges and other corporate purposes.
 Intercompany dividends were paid in 2023, 2022 and 2021 between the following companies: AIC, Allstate Insurance Holdings, LLC ("AIH"), the Corporation, ALIC, American Heritage Life Insurance Company ("AHL") and Allstate Financial Insurance Holdings Corporation ("AFIHC").

 Dividends may not be paid or declared on our common stock and shares of common stock may not be repurchased unless the full dividends for the latest completed dividend period on our preferred stock have been declared and paid or provided for.
 The terms of our outstanding subordinated debentures also prohibit us from declaring or paying any dividends or distributions on our common or preferred stock or redeeming, purchasing, acquiring, or making liquidation payments on our common stock or preferred stock if we have elected to defer interest payments on the subordinated debentures, subject to certain limited exceptions. In 2023, we did not defer interest payments on the subordinated debentures.

 Additional resources to support liquidity are as follows:
 • The Corporation and AIC have access to a $750 million unsecured revolving credit facility that is available for short-term liquidity requirements. In November 2022, the maturity date of this facility was extended to November 2027 and the U.S. dollar benchmark rate was amended from London Interbank Offered Rate to Secured Overnight Financing Rate. The facility is fully subscribed among 11 lenders with the largest commitment being $95 million. The commitments of the lenders are several and no lender is responsible for any other lender's commitment if such lender fails to make a loan under the facility. This facility contains an increase provision that would allow up to an additional $500 million of borrowing, subject to the lenders' commitment. This facility has a financial covenant requiring that we not exceed a 37.5% debt to capitalization ratio as defined in the agreement. This ratio was 23.4% as of December 31, 2023. Although the right to borrow under the facility is not subject to a minimum rating requirement, the costs of maintaining the facility and borrowing under it are based on the ratings of our senior unsecured, unguaranteed long-term debt. There were no borrowings under the credit facility during 2023.
 • To cover short-term cash needs, the Corporation has access to a commercial paper facility with a borrowing capacity limited to any undrawn credit facility balance up to $750 million.
 • As of December 31, 2023, there were no balances outstanding for the credit facility or the commercial paper facility and therefore the remaining borrowing capacity was $750 million under each facility.
 • The Corporation has access to a universal shelf registration statement with the Securities and Exchange Commission that expires in 2024. We can use this shelf registration to issue an unspecified amount of debt securities, common stock (including 638 million shares of treasury stock as of December 31, 2023), preferred stock, depository shares, warrants, stock purchase contracts, stock purchase units and securities of trust subsidiaries. The specific terms of any securities we issue under this registration statement will be provided in the applicable prospectus supplements.
 Long-term contractual obligations
 Defined benefit pension plans and other postretirement benefit plans ("OPEB") Pension plan obligations within the next 12 months represent our planned contributions to certain unfunded non-qualified plans where the benefit obligation exceeds the assets. Obligations beyond 12 months are projected based on the average remaining service period using the current underfunded status of the plans. The OPEB plans' obligations are estimated based on the expected benefits to be paid. See

 Note 18 of the consolidated financial statements for further information.
 Reserves for property and casualty insurance claims and claims expense represent estimated amounts necessary to settle all outstanding claims, including claims that have been IBNR as of the balance sheet date. Estimated timing of payments for reserves is based on our historical experience and our expectation of future payment patterns. The ultimate cost of losses may vary materially from recorded amounts that are our best estimates. See Note 9 of the consolidated financial statements and Application of Critical Accounting Estimates section of the MD&A for further information.
 Reserve for future policy benefits and contractholder funds We estimate the present value of cash payments to be made to contractholders and policyholders. We are currently making payments for contracts where the timing of a portion or all of the payments has been determined by the contract. Contracts such as voluntary accident and health insurance, interest-sensitive life and traditional life insurance involve payment obligations where a portion or all of the amount and timing of future payments is uncertain. We have estimated the timing of payments related to these contracts based on historical experience and our expectation of future payment patterns. Uncertainties relating to these liabilities include mortality, morbidity, customer lapse and withdrawal activity, estimated additional deposits for interest-sensitive life contracts, and renewal premium for life policies, which may significantly impact both the timing and amount of future payments. See Note 10 of the consolidated financial statements for further information.
 Contractual commitments represent investment commitments such as private placements, limited partnership interests and other loans. Limited partnership interests are typically funded over the commitment period which is shorter than the contractual expiration date of the partnership and as a result, the actual timing of the funding may vary.
 We have agreements in place for services we conduct, generally at cost, between subsidiaries relating to insurance, reinsurance, loans and capitalization. All material intercompany transactions have been appropriately eliminated in consolidation. Intercompany transactions among insurance subsidiaries and affiliates have been approved by the appropriate departments of insurance as required.
 For a more detailed discussion of our off-balance sheet arrangements, see Note 7 of the consolidated financial statements.

 The Allstate Corporation 81

 2023 Form 10-K Enterprise Risk and Return Management

 Enterprise Risk and Return Management
 Allstate is subject to significant risks as an insurer and a provider of protection products and services. These risks are discussed in more detail in the Risk Factors section of this document.
 We regularly identify, measure, manage, monitor and report all significant risks. Major categories of enterprise risk are strategic, insurance, investment, financial, operational and culture.
 Allstate manages these risks through an Enterprise Risk and Return Management ("ERRM") framework that includes governance, processes, culture, and activities

 that are performed on an integrated, enterprise-wide basis, following our risk and return principles. Our legal and capital structures are designed to manage capital and solvency on a legal entity basis. Our risk-return principles define how we operate and guide risk and return decision making. These principles state that our priority is to maintain a strong foundation by protecting solvency, complying with laws and acting with integrity. We strive to build strategic value and optimize risk and return.

 Governance ERRM governance includes board oversight, an executive management committee, and enterprise and market-facing business chief risk officers.
 • The Allstate Corporation Board of Directors ("Allstate Board") has overall responsibility for oversight of management's design and implementation of ERRM.
 • The Risk and Return Committee ("RRC") of the Allstate Board oversees effectiveness of the ERRM program, governance structure and risk-related decision-making, while focusing on the Company's overall risk profile.
 • The Audit Committee oversees the effectiveness of internal controls over financial reporting, disclosure controls and procedures as well as

 management's risk control framework and cybersecurity program.
 • The ERRC directs ERRM activities by establishing risk and return targets, determining economic capital levels and monitoring integrated strategies and actions from an enterprise risk and return perspective. The ERRC consists of Allstate's chief executive officer, chief financial officer, chief risk officer, chief legal officer and other senior leaders.
 • Other key committees work with the ERRC to direct ERRM activities, including the Operating Committee, the Operational Risk and Return Council, the Information Security Council, the Internal Compliance and Control Committee, the Environmental, Social, and Governance ("ESG")

 82 www.allstate.com

 2023 Form 10-K Enterprise Risk and Return Management

 Steering Committee, liability governance committees, and investment committees.
 Key risks are assessed and reported through comprehensive ERRM reports prepared for senior management and the RRC. The risk summary report communicates the alignment of Allstate's risk profile with risk and return principles, while providing a perspective on risk positioning. Discussion promotes active engagement with management and the RRC. Internal controls over key risks are managed and reported to senior management and the Audit Committee of the Company through a semi-annual risk control dashboard. Annually, we review risks related to the strategic plan, operating plan and incentive compensation programs with the Allstate Board.
 Framework We apply risk and return principles using an integrated ERRM framework that focuses on assessment, transparency and dialogue. Our framework provides a comprehensive view of risks and is used by senior management and business managers to drive risk-return based decisions. We continually validate and improve our ERRM practices by benchmarking and obtaining external perspectives.
 Management and the ERRC rely on internal and external perspectives to determine an appropriate level of target economic capital. Internal perspectives include enterprise solvency and volatility assessments, review of key operating and model assumptions, and management judgment. Sensitivity testing and scenario analysis are used to gauge the robustness of Allstate's risk, capital and liquidity positions. Analysis of extremely low frequency scenarios is used to assess the sufficiency of capital and contingency options under worst-case outcomes, including unlikely but impactful single events, as well as sequences of multiple tail events. External considerations include NAIC risk-based capital as well as S&P's, Moody's, and A.M. Best's capital adequacy measurement. Our economic capital reflects management's view of the aggregate level of capital necessary to satisfy stakeholder interests, manage Allstate's risk profile and maintain financial strength. The impact of strategic initiatives on enterprise risk is evaluated through the economic capital framework.
 The NAIC has adopted the Risk Management and Own Risk and Solvency Assessment Model Act ("ORSA Model Act"), which has been enacted by our insurance subsidiaries' domiciliary states. The ORSA Model Act requires that insurers maintain a risk management framework and conduct an internal own risk and solvency assessment of the insurer's material risks in normal and stressed environments. Results of the assessment are filed annually.
 Allstate's risk appetite is measured through our economic capital framework. The enterprise risk appetite is cascaded into individual risk limits which set boundaries on the amount of risk we are willing to accept from one specific risk category before escalating for further management discussion and action. Risk limits are established based upon expected returns, volatility, potential tail losses and impact on the enterprise portfolio. To effectively

 operate within risk limits and for risk-return optimization, Allstate establishes risk limits and capital targets specific to each business unit. Allstate's risk management strategies adapt to changes in business and market environments.
 Process Our ERRM framework establishes a basis for transparency and dialogue across the enterprise and for continuous learning by embedding our risk and return management culture of identifying, assessing, managing, monitoring and reporting risks within the organization. Allstate designs business and enterprise strategies that seek to optimize risk-adjusted returns on capital. Risks are managed at both the legal entity and enterprise level.
 A summary of our process to manage each of our major risk categories follows:
 Strategic risk and return management addresses loss associated with inadequate or flawed business planning or strategy setting, including product mix, mergers or acquisitions and market positioning, and unexpected changes within the market or regulatory environment in which Allstate operates. This includes reputational risk, which is the potential for negative publicity regarding a company's conduct or business practices to adversely impact its profitability, operations, or consumer base, or to require costly litigation and other defensive measures.
 We manage strategic risk in part through Allstate Board and senior management strategy reviews that include risk and return assessment of our strategic plans and ongoing monitoring of strategic actions, key assumptions and the external competitive environment. Using the ERRM framework, Allstate designs strategies that seek to optimize risk-adjusted returns associated with taking insurance, investment, and other business risks.
 Insurance risk and return management addresses fluctuations in the timing, frequency and severity of benefits, expenses, and premiums relative to the return expectations inclusive of systemic risk, concentration of insurance exposures, policy terms, reinsurance coverage, and claims handling practices.
 Insurance risk is the potential for loss due to adverse changes in actual or anticipated insurance claims experience (including claims adjustment expenses), net of reinsurance, and lost future profits. Insurance risk exposures include our operating results and financial condition, claims frequency and severity, and catastrophe and severe weather.
 Insurance risk exposures are measured and monitored with different approaches including:
 • Stochastic methods: measure and monitor risks such as natural catastrophes and severe weather. We develop probabilistic estimates of risk based on our exposures, historical observed volatility or industry-recognized models in the case of catastrophe risk.
 • Scenario analysis: measures and monitors risks and estimated losses due to extreme low frequency events that include combined multiple

 The Allstate Corporation 83

 2023 Form 10-K Enterprise Risk and Return Management

 event scenarios across risk categories and time periods.
 Investment risk and return management addresses financial loss due to changes in the valuations of assets held in the Allstate investment portfolio. Such losses may be caused by macro developments, such as changes to interest rates, credit spreads and equity price levels, or could be specific to individual investments in the portfolio. These losses can encompass both daily market volatility and permanent impairments of capital due to credit defaults and equity write-downs.
 Investment risk exposures include interest rate risk, credit spread risk, equity price risk and foreign currency exchange rate risk.
 Investment risk exposures are measured, monitored and limited in a number of ways including:
 • Sensitivity analysis: measures the impact from a unit change in a market risk input.
 • Stochastic and probabilistic estimation of potential losses: combines portfolio risk exposures with historical or recent market volatilities and correlations to assess the potential range of future investment results.
 • Contributions to economic capital: measure the percentage allocations of investment risk and risk types within enterprise economic capital.
 • Scenario analysis: measures material adverse outcomes such as shock scenarios applied to credit, public and private equity markets.
 Some of the stress scenarios are a combination of multiple scenarios across risk categories and over multiple time periods, considering the effects of macroeconomic conditions.
 Financial risk and return management addresses the risk of insufficient cash flows to meet corporate or policyholder needs, risk of inadequate aggregate capital or capital within any subsidiary, inability to access capital markets, credit risk that arises when an external party fails to meet a contractual obligation such as reinsurance for ceded claims, or risk associated with a business counterparty default.
 We actively manage our capital and liquidity levels in light of changing market, economic and business conditions. Our capital position, capital generation capacity, and targeted risk profile provide strategic and financial flexibility.
 We generally assess solvency on a statutory accounting basis, but also consider holding company capital and liquidity needs. Capital at the insurance companies significantly exceeds regulatory risk-based capital requirements and capital levels at the parent holding company provide liquidity and financial flexibility to meet enterprise capital and liquidity requirements.

 Operational risk and return management addresses loss as a result of the failure of people, processes, or systems. Operational risk exposures include human capital, privacy, regulatory compliance, ethics, fraud, system availability, cybersecurity, data quality, disaster recovery and business continuity.
 Operational risk is managed at the enterprise and market-facing business levels, through an integrated Operational Risk and Return Management ("ORRM") framework that is anchored to the ERRM Learning Loop, which depicts the five components of effective risk management. The Learning Loop is a continual process which includes risk identification, measurement, management, monitoring, and reporting of risk.
 From time to time, we engage independent advisers to assess and consult on operational risks. We also perform internal risk reviews of the quality of our operational risk program and identify opportunities to strengthen our internal controls.
 Culture risk and return management addresses the potential for loss of stakeholder value from a suboptimal work environment, missed opportunities, or ineffective risk management practices. Allstate defines organization culture as a self-sustaining system of shared values, principles and priorities that shape beliefs, drive behavior and influence decision-making within an organization. Allstate's approach is grounded in its Risk and Return Principles and organized by Our Shared Purpose.
 Culture is managed using a set of cultural risk categories established as a basis for assessment and measurement, and the Learning Loop is applied to ensure continuous improvement. Culture risk assessments, informed by both quantitative metrics and qualitative judgment, are shared and discussed with the ERRC, RRC and Compensation and Human Capital Committee throughout the year. To strengthen oversight, the Culture Risk and Return Management ("CRRM") team partners with Human Resources and the broader organization to enhance the sophistication of the CRRM framework, including the following key components:
 • Key risk categories, defining the most important areas of culture to track and enhance.
 • Key risk indicators, reflecting the health of the system, providing early warnings, and helping Allstate prioritize risk and return activities.
 • Governance, ensuring timely discussion, escalation, and prioritization of issues, as well as identification of opportunities.
 Many risk drivers impact more than one of these key risk categories. Examples include risks related to inflation and ESG factors. Such risks are managed within processes listed above, but overall strategy is coordinated at the enterprise level, and holistic governance is provided by cross-functional committees such as the ERRC.

 Application of Critical Accounting Estimates
 The preparation of financial statements in conformity with GAAP requires management to adopt accounting policies and make estimates and assumptions that affect amounts reported in the consolidated financial statements. The most critical estimates, presented in the order they appear in the Consolidated Statements of Financial Position, include those used in determining:
 • Fair value of financial assets
 • Impairment of fixed income securities with credit losses
 • Evaluation of goodwill
 • Reserve for property and casualty insurance claims and claims expense estimation
 • Pension and other postretirement plans net costs and assumptions
 In making these determinations, management makes subjective and complex judgments that frequently require estimates about matters that are inherently uncertain. Many of these policies, estimates and related judgments are common in the insurance and financial services industries; others are specific to our businesses and operations. It is reasonably likely that changes in these estimates could occur from period to period and result in a material impact on our consolidated financial statements.
 A summary of each of these critical accounting estimates follows. For a more detailed discussion of the effect of these estimates on our consolidated financial statements, and the judgments and assumptions related to these estimates, see the referenced sections of this document. For a more detailed summary of our significant accounting policies, see the notes to the consolidated financial statements.
 Fair value of financial assets Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We are responsible for the determination of fair value of financial assets and the supporting assumptions and methodologies. We use independent third-party valuation service providers, broker quotes and internal pricing methods to determine fair values. We utilize only one single quote or price to value each financial instrument in our financial statements.
 Valuation service providers typically obtain data about market transactions and other key valuation model inputs from multiple sources and, through the use of proprietary models, produce valuation information in the form of a single fair value for individual fixed income and other securities for which a fair value has been requested under the terms of our agreements. The inputs used by the valuation service providers include, but are not limited to, market prices from recently completed transactions and transactions of comparable securities, interest rate yield curves, credit spreads, liquidity spreads, currency rates, and

 other information, as applicable. Credit and liquidity spreads are typically implied from completed transactions and transactions of comparable securities. Valuation service providers also use proprietary discounted cash flow models that are widely accepted in the financial services industry and similar to those used by other market participants to value the same financial instruments. The valuation models take into account, among other things, market observable information (as described above) as of the measurement date, as well as the specific attributes of the security being valued including its term, interest rate, credit rating, industry sector, and where applicable, collateral quality and other issue or issuer specific information. Executing valuation models effectively requires seasoned professional judgment and experience. For certain equity securities, valuation service providers provide market quotations for completed transactions on the measurement date. In cases where market transactions or other market observable data is limited, the extent to which judgment is applied varies inversely with the availability of market observable information.
 For certain of our financial assets measured at fair value, where our valuation service providers cannot provide fair value determinations, we obtain a single non-binding price quote from a broker familiar with the security who, similar to our valuation service providers, may consider transactions or activity in similar securities among other information. The brokers providing price quotes are generally from the brokerage divisions of financial institutions with market making, underwriting and distribution expertise regarding the security subject to valuation.
 The fair value of certain financial assets, including privately placed corporate fixed income securities and free-standing derivatives, for which our valuation service providers or brokers do not provide fair value determinations, is developed using valuation methods and models widely accepted in the financial services industry. Our internal pricing methods are primarily based on models using discounted cash flow methodologies that develop a single best estimate of fair value. Our models generally incorporate inputs that we believe are representative of inputs other market participants would use to determine fair value of the same instruments, including yield curves, quoted market prices of comparable securities or instruments, published credit spreads, and other applicable market data as well as instrument-specific characteristics that include, but are not limited to, coupon rates, expected cash flows, sector of the issuer, and call provisions. Because judgment is required in developing the fair values of these financial assets, they may differ from the amount actually received to sell an asset in an orderly transaction between market participants at the measurement date. Moreover, the use of different valuation assumptions may have a material effect on the financial assets' fair values.
 For most of our financial assets measured at fair value, all significant inputs are based on or corroborated by market observable data, and

 The Allstate Corporation 85

 significant management judgment does not affect the periodic determination of fair value. The determination of fair value using discounted cash flow models involves management judgment when significant model inputs are not based on or corroborated by market observable data. However, where market observable data is available, it takes precedence, and as a result, no range of reasonably likely inputs exists from which the basis of a sensitivity analysis could be constructed.
 We gain assurance that our financial assets are appropriately valued through the execution of various processes and controls designed to ensure the overall reasonableness and consistent application of valuation methodologies, including inputs and assumptions, and compliance with accounting standards. For fair values received from third parties or internally estimated, our processes and controls are designed to ensure that the valuation methodologies are appropriate and consistently applied, the inputs and assumptions are reasonable and consistent with the objective of determining fair value, and the fair values are accurately recorded. For example, on a continuing basis, we assess the reasonableness of individual fair values that have stale security prices or that exceed certain thresholds as compared to previous fair values received from valuation service providers or brokers or derived from internal models. We perform procedures to understand and assess the methodologies, processes and controls of valuation service providers. In addition, we may validate the reasonableness of fair values by comparing information obtained from

 valuation service providers or brokers to other third-party valuation sources for selected securities. We perform ongoing price validation procedures such as back-testing of actual sales, which corroborate the various inputs used in internal models to market observable data. When fair value determinations are expected to be more variable, we validate them through reviews by members of management who have relevant expertise and who are independent of those charged with executing investment transactions.
 During periods of high volatility or market disruption, we may perform an analysis to determine whether there has been a significant decrease in the volume and level of activity for the asset when compared to normal market activity, and if so, whether transactions may not be orderly. Among the indicators we consider in determining whether a significant decrease in the volume and level of market activity for a specific asset has occurred include the level of new issuances in the primary market, trading volume in the secondary market, level of credit spreads over historical levels, bid-ask spread, and price consensuses among market participants and sources. If evidence indicates that prices are based on transactions that are not orderly, we place little, if any, weight on the transaction price and will estimate fair value using an internal model. As of December 31, 2023 and 2022, we did not adjust fair values provided by our valuation service providers or brokers or substitute them with an internal model for such securities.

 Impairment of fixed income securities with credit losses For fixed income securities classified as available-for-sale, the difference between amortized cost, net of credit loss allowance ("amortized cost, net") and fair value, net of certain other items and deferred income taxes (as disclosed in Note 5 of the consolidated financial statements), is reported as a component of AOCI on the Consolidated Statements of Financial Position and is not reflected in the operating results of any period until reclassified to net income upon the consummation of a transaction with an unrelated third party or when a credit loss allowance is recorded. We have a comprehensive portfolio monitoring process to identify and evaluate each fixed income security that may require a credit loss allowance.
 For each fixed income security in an unrealized loss position, we assess whether management with the

 appropriate authority has made the decision to sell or whether it is more likely than not we will be required to sell the security before recovery of the amortized cost basis for reasons such as liquidity, contractual or regulatory purposes. If a security meets either of these criteria, any existing credit loss allowance would be written-off against the amortized cost basis of the asset along with any remaining unrealized losses, with the incremental losses recorded in earnings.
 If we have not made the decision to sell the fixed income security and it is not more likely than not we will be required to sell the fixed income security before recovery of its amortized cost basis, we evaluate whether we expect to receive cash flows sufficient to recover the entire amortized cost basis of the security. We calculate the estimated recovery value based on the best estimate of future cash flows considering past events, current conditions and reasonable and supportable forecasts. The estimated future cash flows are discounted at the security's current effective rate, and are compared to the amortized cost of the

 86 www.allstate.com

 security. The determination of cash flow estimates is inherently subjective, and methodologies may vary depending on facts and circumstances specific to the security. All reasonably available information relevant to the collectability of the security are considered when developing the estimate of cash flows expected to be collected. That information generally includes, but is not limited to, as applicable, the remaining payment terms of the security, prepayment speeds, the financial condition and future earnings potential of the issue or issuer, expected defaults, expected recoveries, the value of underlying collateral, origination vintage year, geographic concentration of underlying collateral, available reserves or escrows, current subordination levels, third-party guarantees and other credit enhancements. Other information, such as industry analyst reports and forecasts, sector credit ratings, financial condition of the bond insurer for insured fixed income securities, and other market data relevant to the realizability of contractual cash flows, may also be considered. The estimated fair value of collateral will be used to estimate recovery value if we determine that the security is dependent on the liquidation of collateral for ultimate settlement.
 If we do not expect to receive cash flows sufficient to recover the entire amortized cost basis of the fixed income security, a credit loss allowance is recorded in earnings for the shortfall in expected cash flows; however, the amortized cost, net of the credit loss allowance, may not be lower than the fair value of the security. The portion of the unrealized loss related to factors other than credit remains classified in AOCI. If we determine that the fixed income security does not have sufficient cash flow or other information to estimate a recovery value for the security, we may conclude that the entire decline in fair value is deemed to be credit related and the loss is recorded in earnings.
 When a security is sold or otherwise disposed or the security is deemed uncollectible and written off, we remove amounts previously recognized in the credit loss allowance. Recoveries after write-offs are recognized when received.
 For additional detail on investment impairments, see Note 5 of the consolidated financial statements.
 Evaluation of goodwill Goodwill represents the excess of amounts paid for acquiring businesses over the fair value of the net assets acquired, less any impairment of goodwill recognized. Goodwill is recognized when acquired and allocated to reporting units based on which unit is expected to benefit from the synergies of the business combination. Our goodwill reporting units are equivalent to our reportable segments to which goodwill has been assigned: Allstate Protection, Protection Services, and Allstate Health and Benefits.
 The goodwill balance was $3.50 billion at both December 31, 2023 and 2022.
 Upon acquisition, the purchase price of the acquired business is assumed to be its fair value. Subsequently, we estimate the fair value of our businesses in each goodwill reporting unit, utilizing a

 combination of widely accepted valuation techniques including a stock price and market capitalization analysis, discounted cash flow ("DCF") calculations and an estimate of a business's fair value using market to book multiples derived from peer company analysis. The stock price and market capitalization analysis takes into consideration the quoted market price of our outstanding common stock and includes a control premium, derived from relevant historical acquisition activity, in determining the estimated fair value of the consolidated entity before allocating that fair value to individual reporting units. The DCF analysis utilizes long term assumptions for revenues, investment income, benefits, claims, other operating expenses and income taxes to produce projections of both income and cash flows available for dividends that are present valued using the weighted average cost of capital. Market to book multiples represent the mean market to book multiple for selected peer companies with operations similar to each goodwill reporting unit to which the multiple is applied. The outputs from these methods are weighted based on the nature of the business and the relative amount of market observable assumptions supporting the estimates. The computed values are then weighted to reflect the fair value estimate based on the specific attributes of each goodwill reporting unit.
 Estimating the fair value of reporting units is a subjective process that involves the use of significant estimates by management. Changes in market inputs or other events impacting the fair value of these businesses, including discount rates, operating results, investment returns, strategies and growth rate assumptions, among other factors, could result in goodwill impairments, resulting in a charge to income. Certain of our goodwill reporting units are comprised of a combination of legacy and acquired businesses and as a result have substantial internally generated and unrecognized intangibles and fair values that significantly exceed their carrying values.
 The most significant assumptions utilized in the determination of the estimated fair value of the Protection Services reporting unit are the earnings growth rate and discount rate. The earnings growth rate in the DCF projection period is based on the business strategy for the reporting unit.
 The discount rate, which is consistent with the weighted average cost of capital expected by a market participant, is based upon industry specific required rates of return, including consideration of both debt and equity components of the capital structure. Our discount rate may be impacted by changes in the risk-free rate, cost of debt, equity risk premium and entity specific risks.
 Changes in our growth assumptions, including the risk of loss of key customers, or adverse changes in the discount rates could result in a decline in fair value and result in a goodwill impairment charge.

 Reserve for property and casualty insurance claims and claims expense estimation Reserves are established to provide for the estimated costs of paying claims and claims expenses under insurance policies we have issued. These reserves are an estimate of amounts necessary to settle all outstanding claims, including estimates of all expenses associated with processing and settling incurred claims and IBNR, less the amount of paid losses, as of the financial statement date. Total reserves comprise three major components: case (established by claim adjusters), supplemental, and IBNR. Estimating the ultimate cost of claims and claims expenses is an inherently uncertain and complex process involving a high degree of judgment and is subject to the evaluation of numerous variables. Underwriting results are significantly influenced by estimates of property and casualty insurance claims and claims expense reserves.
 Reserves are established for each business segment and line of business, independently of business segment management. The significant lines of business are auto, homeowners, and other personal lines for Allstate Protection, and asbestos, environmental, and other run-off lines for Run-off Property-Liability. Allstate Protection's current period claims are typically reported promptly with relatively little reporting lag between the date of occurrence and the date the loss is reported. Auto and homeowners liability losses generally take an average of about two years to settle, while auto physical damage, homeowners property and other personal lines generally have an average settlement time of less than one year. Liability losses, especially those involving litigation, can take several years to resolve. Run-off Property-Liability involves long-tail losses, such as those related to asbestos and environmental claims, which often involve substantial reporting lags and extended times to settle.
 We update most of our reserve estimates quarterly and as new data and information become available or as events emerge that may affect the resolution of unsettled claims. Changes in prior reserve estimates (reserve reestimates), which may be material, are determined by comparing updated estimates of ultimate losses to prior estimates, with the differences recorded as property and casualty insurance claims and claims expense in the Consolidated Statements of Operations in the period such changes are determined.
 The actuarial methods used to develop reserve estimates Reserve estimates are derived by using several different actuarial estimation methods that are variations on one primary actuarial technique. The actuarial technique is known as a "chain ladder" estimation process in which historical loss patterns are applied to actual paid losses and reported losses (paid losses plus individual case reserves established by claim adjusters) for an accident year or a report year to create an estimate of how losses are likely to develop over time. An accident year refers to classifying claims based on the year in which the claims occurred. A report year refers to classifying claims based on the year in which the claims are reported. Both

 classifications are used to prepare estimates of required reserves for payments to be made in the future. The key assumptions affecting our reserve estimates comprise data elements including claim counts, paid losses, case reserves, and development factors calculated with this data.
 In the chain ladder estimation technique, a ratio (development factor) is calculated which compares current period results to results in the prior period for each accident year. The effects of inflation are implicitly considered in the reserving process, as development factors use historic data that incorporates inflation from recent prior periods in estimating future loss costs. The development factor estimation methodology may require modification when data changes due to changing claim reporting practices, changing claim settlement patterns, external regulatory or financial influences, or contractual coverage changes. Changes in such items and inflation can result in increased variability in loss costs and reserve estimates. Actuarial judgment is then applied to develop a best estimate of gross ultimate losses. These developments are discussed further in the loss ratio disclosures within the Allstate Protection Segment and the Property and Casualty Insurance Claims and Claims Expense Reserves sections of the MD&A. See the Run-off Property-Liability reserve estimates section for specific disclosures of industry and actuarial best practices for this segment.
 How reserve estimates are established and updated Reserve estimates are developed at a detailed level, and the results are aggregated to form a consolidated reserve estimate. The detailed estimates include each line of insurance, major components of losses (such as coverages and perils), major states or groups of states and for reported losses and IBNR. Development factors are calculated for data elements such as claim counts reported and settled, paid losses, and paid losses combined with case reserves. The historical development patterns for these data elements are used to calculate reserve estimates. Based on this review, our best estimate of required reserves is recorded.
 Reserves are reestimated quarterly and periodically throughout the year, by combining historical results with current actual results to calculate new development factors. This process continuously incorporates the historic and latest actual trends, and other underlying changes in the data elements used to calculate reserve estimates. New development factors are likely to differ from previous development factors used in prior reserve estimates because actual results occur differently than the assumptions contained in the previous development factor calculations. When actual development of these data elements is different than the historical development pattern used in a prior period reserve estimate, a new reserve is determined. The difference between indicated reserves based on new reserve estimates and recorded reserves (the previous estimate) is the amount of reserve reestimate. This amount, which could be material and vary significantly from period to period is recognized as an increase or decrease in Property and casualty

 insurance claims and claims expense in the Consolidated Statements of Operations. A more detailed discussion of reserve reestimates is presented

 in the Property and Casualty Insurance Claims and Claims Expense Reserves section of the MD&A.

 Allstate Protection reserve estimate
 Factors affecting reserve estimates Reserve estimates are developed based on the processes and historical development trends described above. These estimates are considered in conjunction with known facts and interpretations of circumstances and factors including our experience with similar cases, actual claims paid, historical trends involving claim payment patterns and pending levels of unpaid claims, loss management programs, product mix and contractual terms, changes in laws and regulations, judicial decisions, and economic conditions. When we experience changes of the type previously mentioned, we apply actuarial judgment in the determination and selection of development factors considered more reflective of the new trends, such as combining shorter or longer periods of historical results with current actual results to produce development factors used to reestimate our reserves. For example:

 • Supply chain disruptions and labor shortages, higher used car prices, labor and part cost increases, unemployment levels, changes in commuting activity and driving behavior have and may continue to lead to historical development trends being less predictive of future loss development, potentially creating additional reserve variability.
 • If a legal change is expected to have a significant impact on the development of claim severity for a coverage which is part of a particular line of insurance in a specific state, judgment is applied to determine appropriate development factors that will most accurately reflect the expected impact on that specific estimate.
 • A change in economic conditions is expected to affect the cost of repairs to damaged autos or property for a particular line, coverage, or state, actuarial judgment is applied to determine appropriate development factors to use in the reserve estimate that will most accurately reflect the expected impacts on severity development.
 Case and supplemental reserves
 • As claims are reported, for certain liability claims of sufficient size and complexity, the field adjusting staff establishes case reserve estimates of ultimate cost, based on their assessment of facts and circumstances related to each individual claim.
 • For other claims which occur in large volumes and settle in a relatively short time frame, it is not practical or efficient to set case reserves for each claim, and a statistical case reserve is set for these claims based on estimation techniques described above.
 • In the normal course of business, we may also supplement our claims processes by utilizing third-party adjusters, appraisers, engineers, inspectors, and other professionals and information sources to assess and settle catastrophe and non-catastrophe related claims.

 The Allstate Corporation 89

 • Historically, the case reserves set by the field adjusting staff have not proven to be an entirely accurate estimate of the ultimate cost of claims. To provide for this, a development reserve is estimated using the processes described above and allocated to pending claims as a supplement to case reserves.
 • Typically, the case, including statistical case, and supplemental development reserves comprise about 90% of total reserves.
 Incurred but not reported ("IBNR")
 • IBNR can be a small percentage of reserves for relatively short-term claims, such as auto physical damage claims, or a large percentage of reserves for claims that have uncertain payout requirements over a long period of time, such as auto injury and MCCA claims.
 • Comprises about 10% of total reserves.
 Generally, the initial reserves for a new accident year are established based on actual claim frequency and severity assumptions for different business segments, lines and coverages based on historical relationships to relevant inflation indicators. Reserves for prior accident years are statistically determined using processes described above. Changes in auto claim frequency may result from changes in mix of business, driving behaviors, miles driven or other macroeconomic factors. Changes in auto current year claim severity are generally influenced by inflation in the medical and auto repair sectors of the economy, the effectiveness and efficiency of our claim settlements and changes in mix of claim type. Injury claims are affected largely by medical inflation, treatment trends, attorney representation and litigation costs while physical damage claims are affected largely by auto repair cost inflation, used car prices, length of claim resolution and the timing of receipt of third-party carrier claims.
 We mitigate these effects through various loss management programs. For auto physical damage coverages, we monitor our rate of increase in average cost per claim against the auto maintenance, repair, parts and equipment price indices. We believe our claim settlement initiatives, such as improvements to the claim review and settlement process, the use of special investigative units to detect fraud and handle suspect claims, litigation management and defense strategies, as well as various other loss management initiatives underway, contribute to the mitigation of injury and physical damage severity trends.
 Changes in homeowners current year claim severity are generally influenced by inflation in the cost of building materials, the cost of construction and property repair services, the cost of replacing home furnishings and other contents, the types of claims that qualify for coverage, deductibles, other economic and environmental factors and the effectiveness of our claim practices.
 As loss experience for the current year develops for each type of loss, it is monitored relative to initial assumptions until it is judged to have sufficient statistical credibility. From that point in time forward,

 reserves are reestimated using statistical actuarial processes to reflect the impact actual loss trends have on development factors incorporated into the actuarial estimation processes.
 Causes of reserve estimate uncertainty Since reserves are estimates of unpaid portions of claims and claims expenses for claims that have occurred, including IBNR losses, the establishment of appropriate reserves, including reserves for catastrophe losses, requires regular reevaluation and refinement of estimates to determine our ultimate loss estimate.
 At each reporting date, the highest degree of uncertainty in estimates for most of our losses from ongoing businesses arise from claims remaining to be settled for the current accident year and the most recent preceding accident year. The greatest degree of uncertainty exists in the current accident year because the current accident year contains the greatest proportion of losses that have not been reported or settled as well as heightened uncertainty for claims that involve litigation or take longer to settle during periods of rapidly increasing loss costs, but must be estimated as of the current reporting date. Most of these losses relate to damaged property such as automobiles and homes, and medical care for injuries from accidents. During the first year after the end of an accident year, a large portion of the total losses for that accident year are settled. When accident year losses paid through the end of the first year following the initial accident year are incorporated into updated actuarial estimates, the trends inherent in the settlement of claims emerge more clearly. After the second year, the losses that we pay for an accident year typically relate to claims that are more difficult to settle, such as those involving serious injuries or litigation. Private passenger auto insurance provides a good illustration of the uncertainty of future loss estimates: our typical annual percentage payout of reserves remaining at December 31 for an accident year is approximately 50% in the first year after the end of the accident year, 20% in the second year, 10% in the third year, 10% in the fourth year, and the remaining 10% thereafter.
 Reserves for catastrophe losses Catastrophe losses are an inherent risk of the property and casualty insurance industry that have contributed, and will continue to contribute, to potentially material year-to-year fluctuations in our results of operations and financial position. We define a "catastrophe" as an event that produces pre-tax losses before reinsurance in excess of $1 million and involves multiple first party policyholders, or a winter weather event that produces a number of claims in excess of a preset, per-event threshold of average claims in a specific area, occurring within a certain amount of time following the event. Catastrophes are caused by various natural events including high winds, winter storms and freezes, tornadoes, hailstorms, wildfires, tropical storms, tsunamis, hurricanes, earthquakes and volcanoes.
 We are also exposed to man-made catastrophic events, such as certain types of terrorism, civil unrest, wildfires or industrial accidents. The nature and level of

 90 www.allstate.com

 catastrophes in any period cannot be reliably predicted.
 The estimation of claims and claims expense reserves for catastrophe losses also comprises estimates of losses from reported claims and IBNR, primarily for damage to property. In general, our estimates for catastrophe reserves are based on claim adjuster inspections and the application of historical loss development factors as described above. However, depending on the nature of the catastrophe, the estimation process can be further complicated. For example, for hurricanes, complications could include the inability of insureds to promptly report losses, limitations placed on claims adjusting staff affecting their ability to inspect losses, determining whether losses are covered by our homeowners policy (generally for damage caused by wind or wind driven rain) or specifically excluded coverage caused by flood, exposure to mold damage, and the effects of numerous other considerations, including the timing of a catastrophe in relation to other events, such as at or near the end of a financial reporting period, which can affect the availability of information needed to estimate reserves for that reporting period. In these situations, we may need to adapt our practices to accommodate these circumstances in order to determine a best estimate of our losses from a catastrophe. For example, to complete estimates for certain areas affected by catastrophes not yet inspected by our claims adjusting staff, or where we believed our historical loss development factors were not predictive, we rely on analysis of actual claim notices received compared to total PIF, as well as visual, governmental and third-party information, including aerial photos, using satellites, aircrafts and drones, area observations, and data on wind speed and flood depth to the extent available.
 Potential variability in reserve estimates Reserve estimates, by their nature, are very complex to determine, subject to significant judgment, and represent approximations rather than an exact determination for each outstanding claim, including claims incurred but not reported. Accordingly, as actual claims, paid losses, and case reserve results emerge, our estimate of the ultimate cost to settle will differ from previous estimates.
 The reserve liability recorded in the Consolidated Statements of Financial Position represents the aggregation of numerous analyses by each business segment, line of insurance, major types of losses (such as coverages and perils), and individual states or groups of states for reported losses and IBNR. Because of this detailed approach to our reserve analysis, there is not a single set of assumptions that determines our reserve estimates at the consolidated level or that management believes can produce a statistically credible or reliable actuarial reserve range that would be meaningful.
 To develop a statistical indication of potential reserve variability within reasonably likely possible outcomes, an actuarial technique (stochastic modeling) is applied to the countrywide consolidated data elements for paid losses and paid losses combined

 with case reserves separately for injury losses, auto physical damage losses, and homeowners insurance losses excluding catastrophe losses. Based on the combined historical variability of the development factors calculated for these data elements, an estimate of the standard error or standard deviation around these reserve estimates is calculated within each accident year for the last twelve years for each type of loss. The variability of these reserve estimates within one standard deviation of the mean (a measure of frequency of dispersion often viewed to be an acceptable level of accuracy) is believed by management to represent a reasonable and statistically probable measure of potential variability. Based on our products and coverages, historical experience, the statistical credibility of our extensive data and stochastic modeling of actuarial chain ladder methodologies used to develop reserve estimates, we have derived the potential standard deviation and impact to net income to our Allstate Protection reserves, excluding catastrophe losses, as shown below. Catastrophe losses are also an inherent risk of the property and casualty insurance industry that have contributed, and will continue to contribute, to potentially material year-to-year fluctuations in our results of operations and financial position.

 Although this evaluation reflects most reasonably likely outcomes, it is possible the final outcome may fall below or above these amounts. Historical variability of reserve estimates is reported in the Property and Casualty Insurance Claims and Claims Expense Reserves section of the MD&A.
 The Company regularly updates its reserve estimates as new information becomes available and as events unfold that may affect the resolution of unsettled claims. Changes in reserve estimates, which may be material, are reported in property and casualty insurance claims and claims expense in the Consolidated Statements of Operations in the period such changes are determined. Management believes that the reserve for property and casualty insurance claims and claims expense, net of recoverables, is appropriately established in the aggregate and adequate to cover the ultimate net cost of reported and unreported claims arising from losses which had occurred by the date of the Consolidated Statements of Financial Position based on available facts, laws and regulations.

 Reserves for Michigan and New Jersey unlimited personal injury protection Claims and claims expense reserves include reserves for Michigan mandatory unlimited personal injury protection coverage to insureds involved in qualifying motor vehicle accidents. The administration of this program is through the MCCA, a state-mandated, non-profit association of which all insurers actively writing automobile coverage in Michigan are members.
 The process employed to estimate MCCA covered losses involves a number of activities including the comprehensive review and interpretation of MCCA actuarial reports, other MCCA members' reports and our personal injury protection loss trends which have increased in severity over time. A significant portion of incurred claim reserves can be attributed to a small number of catastrophic claims and thus a large portion of the recoverable is similarly concentrated. We conduct comprehensive claim file reviews to develop case reserve type estimates of specific claims, which inform our view of future claim development and longevity of claimants. Each year, we update the actuarial estimate of our ultimate reserves and recoverables. We report our paid and unpaid claims based on MCCA requirements. The MCCA develops its own reserving estimates based on its own reserve methodologies, which may not align with our estimations. The MCCA does not provide member companies with its estimate of a company's claim costs.
 We provide similar personal injury protection coverage in New Jersey for auto policies issued or renewed in New Jersey prior to 1991 that is administered by PLIGA. We use similar actuarial estimating techniques as for the MCCA exposures to estimate loss reserves for unlimited personal injury protection coverage for policies covered by PLIGA. Unlimited coverage was not offered after 1991; therefore, no new claimants are being added.
 Reserve estimates are confidential and proprietary and by their nature are very complex to determine and subject to significant judgments. Reserve estimates do not represent an exact determination for each outstanding claim. Claims may be subject to litigation. As actual claims, paid losses and case reserve results emerge, our estimate of the ultimate cost to settle may be materially greater or less than previously estimated amounts.
 For additional information related to indemnification recoverables, see Item 1 - Regulation, Indemnification Programs and Note 11 of the consolidated financial statements.
 Adequacy of reserve estimates We believe our net claims and claims expense reserves are appropriately established based on available methodologies, facts, laws and regulations. Additionally, we rely on historical claims experience to inform the level of the recorded reserve. We calculate and record a single best reserve estimate, in conformance with generally accepted actuarial standards and practices, for each line of insurance, its components (coverages and perils) and state, for reported losses and for IBNR losses, and as a

 result we believe that no other estimate is better than our recorded amount. Due to the uncertainties involved, the ultimate cost of losses may vary materially from recorded amounts, which are based on our best estimates.
 Run-off Property-Liability reserve estimates
 Characteristics of Run-off exposure Our exposure to asbestos, environmental and other run-off claims arise principally from assumed reinsurance coverage written during the 1960s through the mid-1980s, including reinsurance on primary insurance written on large U.S. companies, and from direct excess commercial insurance written from 1972 through 1985, including substantial excess general liability coverages on large U.S. companies. Additional exposure stems from direct primary commercial insurance written during the 1960s through the mid-1980s. Asbestos claims relate primarily to bodily injuries asserted by claimants who were exposed to asbestos or products containing asbestos. Environmental claims relate primarily to pollution and related clean-up costs. Other run-off claims exposures primarily relate to general liability and product liability mass tort claims, such as those for medical devices and other products, workers' compensation claims and claims for various other coverage exposures other than asbestos and environmental.
 In 1986, the general liability policy form used by us and others in the property and casualty industry was amended to introduce an "absolute pollution exclusion," which excluded coverage for environmental damage claims, and to add an asbestos exclusion. Most general liability policies issued prior to 1987 contain annual aggregate limits for product liability coverage. General liability policies issued in 1987 and thereafter contain annual aggregate limits for product liability coverage and annual aggregate limits for all coverages. Our experience to date is that these policy form changes have limited the extent of our exposure to environmental and asbestos claim risks.
 Our exposure to liability for asbestos, environmental and other run-off claims losses manifests differently depending on whether it arises from assumed reinsurance coverage, direct excess commercial insurance or direct primary commercial insurance.
 Direct excess commercial insurance and reinsurance involve coverage written by us for specific layers of protection above retentions and other insurance plans and largely has resulted in asbestos, environmental and mass tort claims. The nature of excess coverage and reinsurance provided to other insurers limits our exposure to loss to specific layers of protection in excess of policyholder retention on their primary insurance plans. Our exposure is further limited by the significant reinsurance that we had purchased on our direct excess business.
 Our assumed reinsurance business involved writing generally small participations in other insurers' reinsurance programs. The reinsured losses in which we participate may be a proportion of all eligible losses or eligible losses in excess of defined retentions. Of the

 92 www.allstate.com

 majority of our assumed reinsurance exposure, approximately 85%, is for excess of loss coverage, while the remaining 15% is for pro-rata coverage.
 Our direct primary commercial insurance business comprises a cross section of policyholders engaged in many diverse business sectors throughout the country and did not include coverage to large asbestos manufacturers.
 How reserve estimates are established and updated We conduct an annual review in the third quarter to evaluate, establish and adjust as necessary, asbestos, environmental and other run-off claims reserves. Changes to reserves are recorded in the reporting period in which they are determined. Using established industry and actuarial best practices and assuming no change in the regulatory or economic environment, this detailed and comprehensive methodology determines asbestos reserves based on assessments of the characteristics of exposure (i.e. claim activity, potential liability, jurisdiction, products versus non-products exposure) presented by individual policyholders, and determines environmental reserves based on assessments of the characteristics of exposure (i.e. environmental damages, respective shares of liability of potentially responsible parties, appropriateness and cost of remediation) to pollution and related clean-up costs. The number and cost of these claims are affected by advertising by trial lawyers seeking asbestos plaintiffs, and entities with asbestos exposure seeking bankruptcy protection as a result of asbestos liabilities, initially causing a delay in the reporting of claims, often followed by an acceleration and an increase in claims and claims expenses as settlements occur.
 After evaluating our insureds' probable liabilities for asbestos, environmental and other run-off claims, we evaluate our insureds' coverage programs for such claims. We consider our insureds' total available insurance coverage, including the coverage we issued. We also consider relevant judicial interpretations of policy language and applicable coverage defenses or determinations, if any.
 Evaluation of both the insureds' estimated liabilities and our exposure to the insureds depends heavily on an analysis of the relevant legal issues and litigation environment. This analysis is conducted by our specialized claims adjusting staff and legal counsel. Based on these evaluations, case reserves are established by claims adjusting staff and actuarial analysis is employed to develop an IBNR reserve, which includes estimated potential reserve development and claims that have occurred but have not been reported. As of December 31, 2023 and 2022, IBNR was 55.7% and 55.9%, respectively, of combined net asbestos and environmental reserves.
 For both asbestos and environmental reserves, we also evaluate our historical direct net loss and expense paid and incurred experience to assess any emerging trends, fluctuations or characteristics suggested by the aggregate paid and incurred activity. Other run-off claims reserves are based on considerations similar to those described above, as they relate to the

 characteristics of specific individual coverage exposures.
 Potential reserve estimate variability Establishing net loss reserves for asbestos, environmental and other run-off claims is subject to uncertainties that are much greater than those presented by other types of property and casualty claims. Among the complications are lack of historical data, long reporting delays, uncertainty as to the number and identity of insureds with potential exposure and unresolved legal issues regarding policy coverage; unresolved legal issues regarding the determination, availability and timing of exhaustion of policy limits; plaintiffs' evolving and expanding theories of liability; availability and collectability of recoveries from reinsurance; retrospectively determined premiums and other contractual agreements; estimates of the extent and timing of any contractual liability; the impact of bankruptcy protection sought by various asbestos producers and other asbestos defendants; and other uncertainties. There are also complex legal issues concerning the interpretation of various insurance policy provisions and whether those losses are covered, or were ever intended to be covered, and could be recoverable through retrospectively determined premium, reinsurance or other contractual agreements. Courts have reached different and sometimes inconsistent conclusions as to when losses are deemed to have occurred and which policies provide coverage; what types of losses are covered; whether there is an insurer obligation to defend; how policy limits are determined; how policy exclusions and conditions are applied and interpreted; and whether clean-up costs represent insured property damage. Our reserves for asbestos, environmental and other run-off exposures could be affected by tort reform, class action litigation, and other potential legislation and judicial decisions. Environmental exposures could also be affected by a change in the existing federal Superfund law and similar state statutes. There can be no assurance that any reform legislation will be enacted or that any such legislation will provide for a fair, effective and cost-efficient system for settlement of asbestos or environmental claims. We believe these issues are not likely to be resolved in the near future, and the ultimate costs may vary materially from the amounts currently recorded resulting in material changes in loss reserves. Historical variability of reserve estimates is demonstrated in the Property and Casualty Insurance Claims and Claims Expense Reserves section of the MD&A.
 Adequacy of reserve estimates Management believes its net loss reserves for asbestos, environmental and other run-off claims exposures are appropriately established based on available facts, laws, regulations, and assessments of other pertinent factors and characteristics of exposure (i.e. claim activity, potential liability, jurisdiction, products versus non-products exposure) presented by individual policyholders, assuming no change in the legal, legislative or economic environment. Due to the uncertainties and factors described above, management believes it is not practicable to develop a

 The Allstate Corporation 93

 meaningful range for any such additional net loss reserves that may be required.
 For further discussion of these estimates and quantification of the impact of reserve estimates, reserve reestimates and assumptions, see Note 9 and Note 15 of the consolidated financial statements and the Property and Casualty Insurance Claims and Claims Expense Reserves section of the MD&A.
 Pension and other postretirement plans net costs and assumptions Our defined benefit pension plans cover most U.S. employees. Benefits are provided to plan participants based on a cash balance formula. Certain participants also have a significant portion of their benefits attributable to a former final average pay formula. 79% of the projected benefit obligation ("PBO") of our primary qualified employee plan is related to the former final average pay formula. See Note 18 of the consolidated financial statements for a discussion of these plans and their effect on the consolidated financial statements.
 Our pension and other postretirement benefit costs are calculated using various actuarial assumptions and methodologies. These assumptions include discount rates, health care cost trend rates, inflation, expected returns on plan assets, mortality and other factors. The assumptions utilized in recording the obligations under our pension plans represent our best estimates and we believe they are reasonable based on information as to historical experience and performance as well as other factors that might cause future expectations to differ from past trends.
 Net costs for our defined benefit plans are recognized on the Consolidated Statements of Operations and consist of two elements: 1) costs comprised of service and interest costs, expected return of plan assets, amortization of prior service credit and curtailment gains and losses which are reported in property and casualty claims and claims expense, operating costs and expenses, net

 investment income and, if applicable, restructuring and related charges and 2) remeasurement gains and losses comprised of changes in actuarial assumptions and the difference between actual and expected returns on plan assets which are recognized immediately in earnings as part of pension and other postretirement remeasurement gains and losses.
 We recognize expected returns on plan assets using an unadjusted fair value method. Our policy is to remeasure our pension and postretirement plans on a quarterly basis. We immediately recognize the remeasurement of the projected benefit obligation and plan assets in earnings as it provides greater transparency of our economic obligations in accounting results and better aligns the recognition of the effects of economic and interest rate changes on pension and other postretirement plan assets and liabilities in the year in which the gains and losses are incurred.
 Differences in actual experience and changes in other assumptions affect our pension and other postretirement obligations and expenses. Differences between expected and actual returns on plan assets affect remeasurement gains and losses. The primary factors contributing to pension and postretirement remeasurement gains and losses are: 1) changes in the discount rate used to value pension and postretirement obligations as of the measurement date; 2) differences between the expected and the actual return on plan assets; 3) changes in demographic assumptions, including mortality and participant experience; and 4) changes in lump sum interest rates used to value pension obligations as of the measurement date.
 Pension and other postretirement service cost, interest cost, expected return on plan assets and amortization of prior service credits are allocated to our reportable segments. The pension and other postretirement remeasurement gains and losses are reported in the Corporate and Other segment.

 Impact of assumption changes to net cost for pension and other postretirement plans Remeasurement losses in 2023 primarily related to losses on the remeasurement of the projected benefit obligation driven by a decrease in the liability discount rate, partially offset by gains due to favorable asset performance compared to expected return on plan assets. Remeasurement losses in 2022 primarily related to unfavorable asset performance compared to the expected return on plan assets, partially offset by a reduction in the projected benefit obligation due to an increase in the liability discount rate and changes in

 other assumptions, primarily related to an increase in the long-term lump sum interest rate.
 The discount rate is based on rates at which expected pension benefits attributable to past employee service could effectively be settled on a present value basis at the measurement date. We develop the assumed discount rate by utilizing the weighted average yield of a theoretical dedicated portfolio derived from non-callable bonds and callable bonds with a make-whole provision available in the Bloomberg corporate bond universe having ratings of at least "AA" by S&P or at least "Aa" by Moody's on the

 94 www.allstate.com

 measurement date with cash flows that match expected plan benefit requirements. Significant changes in discount rates, such as those caused by changes in the credit spreads, yield curve, the mix of bonds available in the market, the duration of selected bonds and expected benefit payments, may result in volatility in pension cost. The weighted average discount rate used to measure the benefit obligation decreased to 5.35% at December 31, 2023 compared to 5.64% at December 31, 2022, resulting in remeasurement losses for 2023.
 The expected long-term rate of return on plan assets reflects the average rate of earnings expected on plan assets. While this rate reflects long-term assumptions and is consistent with long-term historical returns, sustained changes in the market or changes in the mix of plan assets may lead to revisions in the assumed long-term rate of return on plan assets that may result in variability of pension cost. Differences between the actual return on plan assets and the expected long-term rate of return on plan assets are immediately recognized through earnings upon remeasurement. Short-term asset performance can differ significantly from the expected rate of return, especially in volatile markets. In 2023, the actual return on plan assets was higher than the expected return

 primarily due to positive equity returns and higher fixed income valuations from lower interest rates and tighter credit spreads. In 2022, the actual return on plan assets was lower than the expected return primarily due to higher interest rates, widening credit spreads and weak equity market performance.
 We complete periodic evaluations of demographic information and historical experience that affects our pension and other postretirement obligations to identify any required changes to long-term actuarial assumptions and methodologies. Demographic assumptions affect both our pension and postretirement plans and include elements such as retirement rates and participation rates in our postretirement programs, among other factors.
 These actuarial assumption updates affect our pension and other postretirement obligations and are incorporated into our best estimates of these assumptions. Remeasurement losses for other assumptions in 2023 primarily related to a decrease in the long-term lump sum interest rate, partially offset by gains from mortality updates. Remeasurement gains for other assumptions in 2022 primarily related to an increase in the long-term lump sum interest rate.

 Regulation and Legal Proceedings
 We are subject to extensive regulation and we are involved in various legal and regulatory actions, all of which have an effect on specific aspects of our business. For a detailed discussion of the legal and regulatory actions in which we are involved, see Note 15 of the consolidated financial statements.

 Pending Accounting Standards
 There are pending accounting standards that we have not implemented because the implementation dates have not yet occurred. For a discussion of these pending standards, see Note 2 of the consolidated financial statements.
 The effect of implementing certain accounting standards on our financial results and financial condition is often based in part on market conditions at the time of implementation of the standard and other factors we are unable to determine prior to implementation. For this reason, we are sometimes unable to estimate the effect of certain pending accounting standards until the relevant authoritative body finalizes these standards or until we implement them.

 Notes to Consolidated Financial Statements

 Note 1
 General

 Basis of presentation
 The accompanying consolidated financial statements include the accounts of The Allstate Corporation (the "Corporation") and its wholly owned subsidiaries, primarily Allstate Insurance Company ("AIC"), a property and casualty insurance company (collectively referred to as the "Company" or "Allstate") and variable interest entities ("VIEs") in which the Company is considered a primary beneficiary. These consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP"). All significant intercompany accounts and transactions have been eliminated. Certain amounts have been reclassified or recast to reflect the application of the new guidance to all in-scope long-duration insurance contracts to conform to current year presentation. Additional details of the new guidance are included in Note 2.
 The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.
 Nature of operations
 Allstate is engaged, principally in the United States, in the property and casualty insurance business. Allstate is one of the country's largest personal property and casualty insurers and is organized into five reportable segments: Allstate Protection, Run-off Property-Liability, Protection Services, Allstate Health and Benefits, and Corporate and Other.
 Allstate's primary business is the sale of private passenger auto and homeowners insurance. The Company also offers several other personal property and casualty insurance products, select commercial property and casualty coverages, consumer product protection plans, device and mobile data collection services and analytic solutions using automotive telematics information, roadside assistance, protection and insurance products, employer voluntary benefits and group accident and health insurance and identity protection. Allstate primarily distributes its products through exclusive agents, financial specialists, independent agents and brokers, major retailers, contact centers and the internet.
 On November 1, 2023, the Company announced that it is pursuing the sale of the Health and Benefits business.

 Discontinued Operations and Held for Sale
 A business is classified as held for sale when management having the authority to approve the action commits to a plan to sell the business, the sale is probable to occur during the next 12 months at a price that is reasonable in relation to its current fair value and certain other criteria are met. A business classified as held for sale is recorded at the lower of its carrying amount or estimated fair value less cost to sell. When the carrying amount of the business exceeds its estimated fair value less cost to sell, a loss is recognized and updated each reporting period as appropriate.
 The Company completed its sale of the life and annuity business in 2021.
 The results of operations of business classified as held for sale are reported as discontinued operations if the disposal represents a strategic shift that will have a major effect on the entity's operations and financial results. The disposal of a reportable segment generally qualifies for discontinued operations presentation.
 When a business is identified for discontinued operations reporting:
 • Results for prior periods are retrospectively reclassified as discontinued operations
 • Results of operations are reported in a single line, net of tax, in the Consolidated Statements of Operations
 • Assets and liabilities are reported as held for sale in the Consolidated Statements of Financial Position in the period in which the business is classified as held for sale
 Additional details by major classification of operating results are included in Note 3.
 Risks and uncertainties
 Allstate has exposure to catastrophic events, including wind/hail, wildfires, tornadoes, hurricanes, tropical storms, earthquakes, severe freeze events, volcanic eruptions, terrorism and industrial accidents.
 Catastrophes, an inherent risk of the property and casualty insurance business, have contributed, and will continue to contribute, to material year-to-year fluctuations in the Company's results of operations and financial position (see Note 9). The nature and level of catastrophic loss experienced in any period cannot be predicted and could be material to results of operations and financial position.

 The Allstate Corporation 103

 The Company considers the following categories and locations to be the greatest areas of potential catastrophe losses:
 • Wildfires — California, Hawaii, Colorado, Oregon and Texas
 • Hurricanes — Major metropolitan centers in counties along the eastern and gulf coasts of the United States

 • Wind/Hail, Rain and Tornado — Texas, Illinois, Georgia and Colorado
 • Earthquakes and fires following earthquakes —Major metropolitan areas near fault lines in the states of California, Oregon, Washington, South Carolina and Kentucky

 Note 2
 Summary of Significant Accounting Policies

 Fixed income securities include bonds and asset-backed securities ("ABS"). Fixed income securities, which may be sold prior to their contractual maturity, are designated as available-for-sale ("AFS") and are carried at fair value. The difference between amortized cost, net of credit loss allowances ("amortized cost, net") and fair value, net of deferred income taxes, is reflected as a component of accumulated other comprehensive income ("AOCI"). The Company excludes accrued interest receivable from the amortized cost basis of its AFS fixed income securities. Cash received from calls and make-whole payments is reflected as a component of proceeds from sales and cash received from maturities and pay-downs is reflected as a component of investment collections within the Consolidated Statements of Cash Flows.
 Equity securities primarily include common stocks, exchange traded and mutual funds, non-redeemable preferred stocks and real estate investment trust equity investments. Certain exchange traded and mutual funds have fixed income securities as their underlying investments. Equity securities are carried at fair value. Equity securities without readily determinable or estimable fair values are measured using the measurement alternative, which is cost less impairment, if any, and adjustments resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer.
 Mortgage loans and bank loans are carried at amortized cost, net, which represent the amount expected to be collected. The Company excludes accrued interest receivable from the amortized cost basis of its mortgage and bank loans. Credit loss allowances are estimates of expected credit losses, established for loans upon origination or purchase, and are established considering all relevant information available, including past events, current conditions, and reasonable and supportable forecasts over the life of the loans. Loans are evaluated on a pooled basis when they share similar risk characteristics; otherwise, they are evaluated individually.
 Investments in limited partnership interests are primarily accounted for in accordance with the equity method of accounting ("EMA") and include interests in private equity funds, real estate funds and other funds. Investments in limited partnership interests purchased prior to January 1, 2018, where the Company's interest is so minor that it exercises virtually no influence over operating and financial policies, are accounted for at

 fair value primarily utilizing the net asset value ("NAV") as a practical expedient to determine fair value.
 Short-term investments, including money market funds, commercial paper, U.S. Treasury bills and other short-term investments, are carried at fair value. Other investments primarily consist of bank loans, policy loans, real estate and derivatives. Bank loans are primarily senior secured corporate loans. Policy loans are carried at unpaid principal balances. Real estate is carried at cost less accumulated depreciation. Derivatives are carried at fair value.
 Investment income primarily consists of interest, dividends, income from limited partnership interests, rental income from real estate, and income from certain derivative transactions.
 Interest is recognized on an accrual basis using the effective yield method and dividends are recorded at the ex-dividend date. Interest income for ABS is determined considering estimated pay-downs, including prepayments, obtained from third-party data sources and internal estimates. Actual prepayment experience is periodically reviewed, and effective yields are recalculated when differences arise between the prepayments originally anticipated and the actual prepayments received and currently anticipated. For ABS of high credit quality with fixed interest rates, the effective yield is recalculated on a retrospective basis. For all others, the effective yield is generally recalculated on a prospective basis. Net investment income for AFS fixed income securities includes the impact of accreting the credit loss allowance for the time value of money. Accrual of income is suspended for fixed income securities when the timing and amount of cash flows expected to be received is not probable. Accrual of income is suspended for mortgage loans and bank loans that are in default or when full and timely collection of principal and interest payments is not probable. Accrued income receivable is monitored for recoverability, and when not expected to be collected, is written off through net investment income. Cash receipts on investments on nonaccrual status are generally recorded as a reduction of amortized cost.
 Income from limited partnership interests carried at fair value is recognized based upon the changes in fair value of the investee's equity primarily determined using NAV. Income from EMA limited partnership interests is recognized based on the Company's share of the partnerships' earnings. Income from EMA limited partnership interests is generally recognized on a three

 104 www.allstate.com

 month delay due to the availability of the related financial statements from investees.
 Net gains and losses on investments and derivatives include gains and losses on investment sales, changes in the credit loss allowances related to fixed income securities, mortgage loans and bank loans, impairments, valuation changes of equity investments, including equity securities and certain limited partnerships where the underlying assets are predominately public equity securities, and periodic changes in fair value and settlements of certain derivatives, including hedge ineffectiveness. Net gains and losses on sales of investments and derivatives are determined on a specific identification basis and are net of credit losses already recognized through an allowance.
 Derivative and embedded derivative financial instruments
 Derivative financial instruments include interest rate swaps, credit default swaps, futures (interest rate and equity), options (including swaptions), warrants and stock rights, foreign currency forwards and total return swaps.
 All derivatives are accounted for on a fair value basis and reported as other investments, other assets and other liabilities and accrued expenses. Embedded derivative instruments subject to bifurcation are also accounted for on a fair value basis and are reported together with the host contract. Cash flows from other derivatives are reported in cash flows from investing activities within the Consolidated Statements of Cash Flows.
 For derivatives for which hedge accounting is not applied, the income statement effects, including fair value gains and losses and accrued periodic settlements, are reported either in net gains and losses on investments and derivatives or in a single line item together with the results of the associated asset or liability for which risks are being managed.
 Securities loaned
 The Company's business activities include securities lending transactions, which are used primarily to generate net investment income. The proceeds received in conjunction with securities lending transactions can be reinvested in short-term investments or fixed income securities. These transactions are short-term in nature, usually 30 days or less.
 The Company receives cash collateral for securities loaned in an amount generally equal to 102 % and 105 % of the fair value of domestic and foreign securities, respectively, and records the related obligations to return the collateral in other liabilities and accrued expenses. The carrying value of these obligations approximates fair value because of their relatively short-term nature. The Company monitors the market value of securities loaned on a daily basis and obtains additional collateral as necessary under the terms of the agreements to mitigate counterparty credit risk.

 The Company maintains the right and ability to repossess the securities loaned on short notice.
 Recognition of premium revenues and contract charges, and related benefits and interest credited
 Property and casualty insurance premiums include premiums from personal lines policies, protection plans, other contracts (primarily protection and insurance products) and roadside assistance.
 Personal lines insurance premiums are deferred and earned on a pro-rata basis over the terms of the policies, typically periods of six or twelve months.
 Revenues related to protection plans, other contracts (primarily protection and insurance products) and roadside assistance are deferred and earned over the term of the contract in a manner that recognizes revenue as obligations under the contracts are fulfilled. Revenues from these products are classified as premiums as the products are backed by insurance. Protection plans and protection and insurance premiums are recognized using a cost-based incurrence method over the term of the contracts, which is generally one to five years. Roadside assistance premiums are recognized evenly over the term of the contract as performance obligations are fulfilled.
 The portion of premiums written applicable to the unexpired terms of the policies is recorded as unearned premiums.

 Protection Services For the year ended December 31, 2023, the Company recognized $ 1.74 billion of property and casualty insurance premiums for Protection Services that were included in the unearned premium balance as of December 31, 2022.
 For the year ended December 31, 2022, the Company recognized $ 1.46 billion of property and casualty insurance premiums for Protection Services that were included in the unearned premium balance as of December 31, 2021.
 The Company expects to recognize approximately $ 1.85 billion, $ 1.43 billion and $ 1.87 billion of the December 31, 2023 unearned premium balance in 2024, 2025 and thereafter, respectively.
 Health and benefits Voluntary accident and health insurance products are expected to remain in force for an extended period and therefore are primarily classified as long-duration contracts. Traditional life insurance products consist principally of products with fixed and guaranteed premiums and benefits, primarily term and whole life insurance products. Premiums from these products are recognized as revenue when due from policyholders, net of any credit loss allowance for uncollectible premiums. Benefits are reflected in

 The Allstate Corporation 105

 accident, health and other policy benefits and recognized over the life of the policy in relation to premiums.
 Interest-sensitive life contracts, such as universal life, are insurance contracts whose terms are not fixed and guaranteed. The terms that may be changed include premiums paid by the contractholder, interest credited to the contractholder account balance and contract charges assessed against the contractholder account balance. Premiums from these contracts are reported as contractholder fund deposits. Contract charges consist of fees assessed against the contractholder account balance for the cost of insurance (mortality risk), contract administration and surrender of the contract prior to contractually specified dates. These contract charges are recognized as revenue when assessed against the contractholder account balance. Benefit payments in excess of the contractholder account balance are reflected in accident, health and other policy benefits.
 Interest credited to contractholder funds, which are reported in accident, health and other policy benefits, represents interest accrued or paid on interest-sensitive life contracts. Crediting rates for interest-sensitive life contracts are adjusted periodically by the Company to reflect current market conditions subject to contractually guaranteed minimum rates.
 Premium installment receivables represent premiums written and not yet collected, net of the credit loss allowance for uncollectible premiums. These receivables are primarily outstanding for one year or less. The Company utilizes historical internal data including aging analyses to estimate allowances under current conditions and for the forecast period. The Company regularly evaluates and updates the data and adjusts its allowance as appropriate.

 Other revenue represents fees collected from policyholders relating to premium installment payments, commissions on sales of non-proprietary products, sales of identity protection services, fee-based services and other revenue transactions. Other revenue is recognized when performance obligations are fulfilled.
 The Company collects service fees in the form of commission and general agent fees by selling policies

 issued by third-party insurance companies. The Company recognizes Medicare-related and other accident and health commission revenues equal to the estimated lifetime value of the revenues at the time when the policy is sold, net of an allowance for estimated policy cancellations, as no further performance obligations exist. The allowance for estimated third-party cancellations is periodically evaluated and adjusted as necessary.
 Deferred policy acquisition costs ("DAC") are related directly to the successful acquisition of new or renewal insurance contracts and are deferred and recognized as an expense over the life of the related contracts. These costs are principally agent and broker remuneration, premium taxes and certain underwriting expenses and are included in amortization of deferred policy acquisition costs on the Consolidated Statements of Operations. All other acquisition costs are expensed as incurred and included in operating costs and expenses.
 Customers of the Company may exchange one insurance policy for another offered by the Company, or make modifications to an existing life, accident and health or property and casualty contract issued by the Company. These transactions are identified as internal replacements for accounting purposes. Internal replacement transactions determined to result in replacement contracts that are substantially unchanged from the replaced contracts are accounted for as continuations of the replaced contracts. Unamortized DAC related to the replaced contracts continue to be deferred and amortized in connection with the replacement contracts. For traditional life, accident and health and property and casualty insurance policies, any changes to unamortized DAC that result from replacement contracts are treated as prospective revisions and any costs associated with the issuance of replacement contracts are characterized as maintenance costs and expensed as incurred.
 Property and casualty insurance For property and casualty insurance, DAC is amortized into income as premiums are earned pro rata over the period of the policy. DAC associated with property and casualty insurance is periodically reviewed for recoverability and adjusted if necessary. Future investment income is considered in determining the recoverability of DAC.
 Long-duration voluntary accident and health insurance, traditional life insurance contracts, and interest-sensitive life insurance contracts Voluntary accident and health insurance and traditional life insurance contracts are grouped by product and issue year into cohorts consistent with the cohorts used to calculate the reserve for future policy benefits ("RFPB"). Interest-sensitive life insurance contracts are grouped into cohorts by issue year, and the issue year is determined based on contract issue date. DAC is amortized on a constant level basis over the expected contract term. The constant level basis used for all cohorts is based on policies-in-force. The expected contract term and mortality, morbidity, and lapse

 106 www.allstate.com

 assumptions are used to calculate both DAC amortization and the RFPB. If actual contract lapses are greater than expected lapses for any cohort, each affected cohort's DAC balance will be reduced in the current period based on the difference between the actual and expected lapses. No adjustments to DAC amortization are recorded if actual contract lapses are less than expected lapses for any cohort. If the Company makes an update to any of its mortality, morbidity, or lapse assumptions, the Company will use the assumptions prospectively to amortize any cohort's remaining DAC over the remaining expected contract term.
 Present value of future profits The costs assigned to the right to receive future cash flows from certain business purchased from other insurers are also classified as DAC in the Consolidated Statements of Financial Position. The costs capitalized represent the present value of future profits expected to be earned over the lives of the contracts acquired.
 The Company amortizes the present value of future profits for long-duration voluntary accident and health insurance, traditional life insurance contracts and interest-sensitive life insurance contracts using the same methodology and assumptions as the amortization of DAC. The present value of future profits for these products is subject to premium deficiency testing.
 For property and casualty insurance, these costs are amortized as profits emerge over the lives of the acquired business and are periodically evaluated for recoverability.
 The present value of future profits was $ 8 million and $ 10 million as of December 31, 2023 and 2022, respectively. Amortization expense of the present value of future profits was $ 2 million, $ 11 million and $ 324 million in 2023, 2022 and 2021, respectively.
 Reinsurance and indemnification
 Reinsurance In the normal course of business, the Company seeks to limit aggregate and single exposure to losses on large risks by purchasing reinsurance. The Company has also used reinsurance to affect the disposition of certain blocks of business. Reinsurance does not extinguish the Company's primary liability under the policies written. Therefore, in addition to establishing allowances as appropriate after evaluating reinsurers' activities related to claims settlement practices and commutations, the Company evaluates reinsurer counterparty credit risk and records reinsurance recoverables net of credit loss allowances. The Company assesses counterparty credit risk for individual reinsurers separately when more relevant or on a pooled basis when shared risk characteristics exist. The evaluation considers the credit quality of the reinsurer and the period over which the recoverable balances are expected to be collected. The Company considers factors including past events, current conditions and reasonable and supportable forecasts in the development of the estimate of credit loss allowances.

 Allowances for property and casualty and accident and health reinsurance recoverables are established primarily through risk-based evaluations.
 The property and casualty recoverable evaluation considers the credit rating of the reinsurer, the period over which the reinsurance recoverable balances are expected to be recovered and other relevant factors including historical experience of reinsurer failures. Reinsurers in liquidation or in default status are evaluated individually using the Company's historical liquidation recovery assumptions and any other relevant information available including the most recent public information related to the financial condition or liquidation status of the reinsurer. For accident and health reinsurance recoverables, the Company uses a probability of default and loss given default model developed independently of the Company to estimate current expected credit losses. The accident and health reinsurance recoverable evaluation utilizes factors including historical industry factors based on the probability of liquidation, and incorporates current loss given default factors reflective of the industry.
 The Company monitors the credit ratings of reinsurer counterparties and evaluates the circumstances surrounding credit rating changes as inputs into its credit loss assessments. Uncollectible reinsurance recoverable balances are written off against the allowances when there is no reasonable expectation of recovery.
 The changes in the allowances are reported in property and casualty insurance claims and claims expense and accident, health and other policy benefits.
 Indemnification The Company also participates in various indemnification mechanisms, including industry pools and facilities, which are reimbursement mechanisms that assess participating insurers for expected insured claims, reimburse participating insurers for qualifying paid claims and permit participating insurers to recoup amounts assessed directly from insureds. Indemnification recoverables are backed by the financial resources of the property and casualty insurance company market participants.
 The design and function of these indemnification programs does not result in the retention of insurance or reinsurance risk by the indemnitee. Based on the Company's evaluation of these programs on an individual basis, the establishment of credit loss allowances is not warranted at this time. The Company has not experienced any historical credit losses related to its indemnification programs. The Company continues to monitor these programs to determine whether any changes from historical experience have emerged or are expected to emerge or whether there have been any changes in the design or administration of the programs that would require establishment of credit loss allowances.
 Revenue recognition The amounts reported as reinsurance and indemnification recoverables include amounts paid and due from reinsurers and indemnitors as well as estimates of amounts expected to be

 The Allstate Corporation 107

 recovered from reinsurers and indemnitors on insurance liabilities that have been incurred but not yet paid. Reinsurance and indemnification recoverables on unpaid losses are estimated based upon assumptions consistent with those used in establishing the liabilities related to the underlying contract. Reinsurance and indemnification premiums are generally reflected in income in a manner consistent with the recognition of premiums on the associated contracts. For catastrophe coverage, the cost of reinsurance premiums is recognized ratably over the contract period to the extent coverage remains available. Certain catastrophe agreements are subject to reinstatement premiums which are recorded as catastrophe losses when earned.
 Goodwill
 Goodwill represents the excess of amounts paid for acquiring businesses over the fair value of the net assets acquired, less any impairment of goodwill recognized. The Company's goodwill reporting units are equivalent to its reportable segments to which goodwill has been assigned: Allstate Protection, Protection Services, and Allstate Health and Benefits.

 Goodwill is recognized when acquired and allocated to reporting units based on which unit is expected to benefit from the synergies of the business combination. Goodwill is not amortized but is tested for impairment at least annually. The Company performs its annual goodwill impairment testing during the fourth quarter of each year based upon data as of the close of the third quarter. Goodwill impairment is measured and recognized as the amount by which a reporting unit's carrying value, including goodwill, exceeds its fair value, not to exceed the carrying amount of goodwill allocated to the reporting unit. The Company also reviews goodwill for impairment whenever events or changes in circumstances, such as deteriorating or adverse market conditions, indicate that it is more likely than not that the carrying amount of the reporting unit including goodwill may exceed the fair value of the reporting unit. The goodwill impairment analysis is performed at the reporting unit level.
 As of December 31, 2023 and 2022, the fair value of the Company's goodwill reporting units exceeded their carrying values.
 Intangible assets
 Intangible assets (reported in other assets) consist of capitalized costs primarily related to acquired distribution and customer relationships, trade names and licenses, technology and other assets. The estimated useful lives of distribution and customer relationships, technology and other intangible assets

 are generally 10 years, 5 years and 5 years, respectively. Intangible assets are carried at cost less accumulated amortization.

 Accumulated amortization of intangible assets was $ 1.80 billion and $ 1.48 billion as of December 31, 2023 and 2022, respectively.
 Trade names and licenses are considered to have an indefinite useful life and are reviewed for impairment at least annually or more frequent if circumstances arise that indicate an impairment may have occurred. An impairment is recognized if the carrying amount of the asset exceeds its estimated fair value.
 Property and equipment
 Property and equipment is carried at cost less accumulated depreciation. Included in property and equipment are capitalized costs related to computer software licenses and software developed for internal use. These costs generally consist of certain external payroll and payroll related costs. Property and equipment depreciation is calculated using the straight-line method over the estimated useful lives of the assets, generally 3 to 10 years for equipment and 40 years for real property. Depreciation expense is reported in operating costs and expenses. Accumulated depreciation on property and equipment was $ 2.59 billion and $ 2.45 billion as of December 31, 2023 and 2022, respectively. Depreciation expense on property and equipment was $ 343 million, $ 335 million and $ 411 million in 2023, 2022 and 2021, respectively. The Company reviews its property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.

 108 www.allstate.com

 Income taxes are accounted for using the asset and liability method under which deferred tax assets and liabilities are recognized for temporary differences between the financial reporting and tax bases of assets and liabilities at the enacted tax rates. A deferred tax asset valuation allowance is established when it is more likely than not such assets will not be realized. The Company recognizes interest expense related to income tax matters in income tax expense and penalties in operating costs and expenses.
 Reserve for property and casualty insurance claims and claims expense
 The reserve for property and casualty insurance claims and claims expense is the estimate of amounts necessary to settle all reported and unreported incurred claims for the ultimate cost of insured property and casualty losses, based upon the facts of each case and the Company's experience with similar cases. Estimated amounts of salvage and subrogation are deducted from the reserve for claims and claims expense. The establishment of appropriate reserves, including reserves for catastrophe losses, is an inherently uncertain and complex process. Reserve estimates are primarily derived using an actuarial estimation process in which historical loss patterns are applied to actual paid losses and reported losses (paid losses plus individual case reserves established by claim adjusters) for an accident or report year to create an estimate of how losses are likely to develop over time. Development factors are calculated quarterly and periodically throughout the year for data elements such as claims reported and settled, paid losses, and paid losses combined with case reserves.
 When the Company experiences changes in the mix or type of claims or changing claim settlement patterns or data, it applies actuarial judgment in the determination and selection of development factors to develop reserve liabilities. The effects of inflation are implicitly considered in the reserving process as a development factor using historic data incorporated as a reasonable estimate of future inflation. The historical development patterns for these data elements are used as the assumptions to calculate reserve estimates, including the reserves for reported and unreported claims; however, when the Company experiences changes it may lead to historical development trends being less predictive of future loss development, potentially creating additional reserve variability. Reserve estimates are regularly reviewed and updated, using the most current data and information available. Any resulting reestimates are reflected in current results of operations.
 Reserve for future policy benefits
 Long-duration voluntary accident and health insurance and traditional life insurance contracts The reserve for future policy benefits ("RFPB") is calculated using the net premium reserving model, which uses the present value of insurance contract benefits less the present value of net premiums. Under the net premium reserving model, the Company computes a net

 premium ratio which is the present value of insurance contract benefits divided by the present value of gross premiums. The present value of contract benefits and gross premiums are determined using the discount rate at contract inception. The net premium ratio is applied to premiums due on a periodic basis to compute the RFPB. The net premium ratio is recomputed at least annually using both actual historical cash flows and future cash flows anticipated over the life of the cohort of contracts subject to measurement. Assumptions including mortality, morbidity, and lapses affect the timing and amount of estimated cash flows used to calculate the RFPB.
 The Company has grouped contracts into cohorts based on product type and issue year. Examples of insurance product types include whole life, term life, critical illness and disability. Issue year is based on the issuance date of the contract to the policyholder, except in the case of contracts acquired in a business combination, where the issue date is based on the acquisition date of the business combination. The RFPB is calculated for contracts in force at the end of each period, which results in the Company recognizing the effects of actual experience in the period it occurs.
 Annually, in the third quarter, the Company obtains historical premiums and benefits information and evaluates future cash flow assumptions that include mortality, morbidity, and lapses, and updates cash flow assumptions as necessary. The Company has elected to not update the expense assumption when annually reviewing and updating future cash flow assumptions. Actual premiums and benefits and any updates to future cash flow assumptions are incorporated into the calculation of an updated net premium ratio. Updates for actual premiums and benefits and changes to future cash flow assumptions will result in a liability remeasurement gain or loss. The first step to determining the liability remeasurement gain or loss is to calculate the RFPB using revised net premiums discounted at the locked-in discount rate set at contract issuance. The result of the first step is then compared to the carrying amount of the RFPB before the updates for actual experience and changes to future cash flow assumptions. The decrease (gain) or increase (loss) in the RFPB is reported as liability remeasurement gain or loss in net income and presented parenthetically as part of accident, health and other policy benefits on the Consolidated Statements of Operations. The updated net premium ratio is used in future quarters to measure the RFPB until the next annual update or an earlier date if the Company determines it is necessary to revise future cash flow assumptions based on available evidence, including actual experience.
 The discount rate assumption is determined using a yield curve approach. The yield curve consists of U.S. dollar-denominated senior unsecured fixed-income securities issued by U.S. companies that have an A credit rating based on the ratings provided by nationally recognized rating agencies that include Moody's, Standard & Poor's, and Fitch. For points on the yield curve that do not have observable yields, the Company uses linear interpolation which calculates the

 The Allstate Corporation 109

 unobservable yield based on the two nearest observable yields, except for any points beyond the last observable yield at 30 years, where interest rates are held constant with the last observable point on the yield curve. The Company updates the current discount rate quarterly and the change in the RFPB resulting from the updated current discount rate is recognized in other comprehensive income ("OCI").
 Accident and health short-duration contracts The RFPB includes unpaid losses and loss adjustment expense ("LAE") reserves for individual and certain voluntary accident and health short-duration contracts and is an estimate of the Company's liability from incurred claims at the end of the reporting period. The unpaid losses and LAE reserves are the result of an ongoing analysis of recent loss development trends and emerging historical experience. Original estimates are increased or decreased as additional information becomes known regarding individual claims. In setting its reserves, the Company reviews its loss data to estimate expected loss development. Management believes that its use of standard actuarial methodology applied to its analyses of its historical experience provides a reasonable estimate of future losses. However, actual future losses may differ from the Company's estimate, and may be affected by future events, including inflation and changes in law and judicial interpretations, which would favorably or unfavorably impact the ultimate settlement of the Company's losses and LAE.
 The anticipated effect of inflation is implicitly considered when estimating liabilities for losses and LAE. In addition to inflation, the average severity of claims is affected by a number of factors that may vary by types and features of policies written. Future average severities are projected from historical trends, adjusted for implemented changes in underwriting standards and policy provisions, as well as general economic trends. These estimated trends are monitored and revised as necessary based on actual development.
 Unpaid losses include a provision for incurred-but-not-reported ("IBNR") reserve estimates representing claims that have occurred but have not yet been reported, some of which are not yet known to the insured, as well as a provision for future development on reported claims. IBNR reserves are generally calculated by first projecting the ultimate cost of all claims that have occurred and then subtracting reported losses and loss expenses. Reported losses include cumulative paid losses and loss expenses plus case reserves.
 Contractholder funds
 Contractholder funds represent interest-bearing liabilities arising primarily from the sale of interest-sensitive life insurance contracts. Contractholder funds primarily comprise cumulative deposits received and interest credited to the contractholder less cumulative contract benefits, surrenders, withdrawals and contract charges for mortality or administrative expenses.

 Pension and other postretirement remeasurement gains and losses
 The Company's policy is to remeasure its pension and postretirement plans on a quarterly basis. Pension and other postretirement gains and losses represent the remeasurement of projected benefit obligations and differences between the expected and actual return on plan assets, which are immediately recognized in earnings and are referred to as pension and other postretirement remeasurement gains and losses on the Consolidated Statements of Operations.
 The primary factors contributing to pension and postretirement remeasurement gains and losses are:

 • Changes in the discount rate used to value pension and postretirement obligations as of the measurement date

 • Differences between the expected and the actual return on plan assets

 • Changes in demographic assumptions, including mortality and participant experience

 • Changes in lump sum interest rates used to value pension obligations as of the measurement date

 Differences in actual experience and changes in other assumptions affect the Company's pension and other postretirement obligations and expenses.
 Pension and other postretirement service cost, interest cost, expected return on plan assets and amortization of prior service credits are allocated to the Company's reportable segments. The pension and other postretirement remeasurement gains and losses are reported in the Corporate and Other segment.
 Legal contingencies
 The Company reviews its lawsuits, regulatory inquiries, and other legal proceedings on an ongoing basis. The Company establishes accruals for such matters at management's best estimate when the Company assesses that it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. The Company's assessment of whether a loss is reasonably possible or probable is based on its assessment of the ultimate outcome of the matter following all appeals. The Company does not include potential recoveries in its estimates of reasonably possible or probable losses. Legal fees are expensed as incurred.
 Debt
 Debt includes senior notes, senior debentures, subordinated debentures and junior subordinated debentures issued by the Corporation. Unamortized debt issuance costs and fair value adjustments are reported in debt and are amortized over the expected period the debt will remain outstanding.
 Equity incentive plans
 The Company has equity incentive plans under which it grants nonqualified stock options, restricted stock units and performance stock awards ("equity awards") to certain employees and directors of the Company. The Company measures the fair value of equity awards at the grant date and recognizes the

 110 www.allstate.com

 expense over the shorter of the period in which the requisite service is rendered or retirement eligibility is attained. The expense for performance stock awards with no market condition is adjusted each period to reflect the performance factor most likely to be achieved at the end of the performance period. The expense for performance stock awards with a market condition is based on the fair value of the awards at the grant date which incorporates the probability of achieving the market condition. In the event the market condition is not met, any previously recognized expense is not reversed. The Company uses a binomial lattice model to determine the fair value of employee stock options. The Company uses a Monte Carlo simulation model to determine the fair value of performance stock awards with a market condition.
 Measurement of credit losses
 The Company carries an allowance for expected credit losses for all financial assets measured at

 amortized cost on the Consolidated Statements of Financial Position. The Company considers past events, current conditions, and reasonable and supportable forecasts in estimating an allowance for credit losses. The Company also carries a credit loss allowance for fixed income securities where applicable and, when amortized cost is reported, it is net of credit loss allowances. For additional information, refer to the Investments, Reinsurance and indemnification or Recognition of premium revenues and contract charges topics of this section.
 The Company also estimates a credit loss allowance for commitments to fund mortgage loans and bank loans unless they are unconditionally cancellable by the Company. The related allowance is reported in other liabilities and accrued expenses.

 Leases
 The Company has certain operating leases for office facilities, computer and office equipment, and vehicles. The Company's leases have remaining lease terms of generally 1 year to 10 years, some of which include options to extend the leases for up to 20 years, and some of which include options to terminate the leases within 45 days.
 The Company determines if an arrangement is a lease at inception. Leases with an initial term less than one year are not recorded on the balance sheet and the lease costs for these leases are recorded as an expense on a straight-line basis over the lease term. Operating leases with terms greater than one year result in a lease liability recorded in other liabilities and accrued expenses with a corresponding right-of-use ("ROU") asset recorded in other assets on the Consolidated Statements of Financial Position. As of December 31, 2023 and 2022, the Company had $ 265 million and $ 343 million in lease liabilities and $ 163 million and $ 234 million in ROU assets, respectively.
 Operating lease liabilities are recognized at the commencement date based on the present value of future minimum lease payments over the lease term. ROU assets are recognized based on the

 corresponding lease liabilities adjusted for qualifying initial direct costs, prepaid or accrued lease payments and unamortized lease incentives. As most of the Company's leases do not disclose the implicit interest rate, the Company uses collateralized incremental borrowing rates based on information available at lease commencement when determining the present value of future lease payments. The Company has lease agreements with lease and non-lease components, which are accounted for as a single lease. Lease terms may include options to extend or terminate the lease which are incorporated into the Company's measurements when it is reasonably certain that the Company will exercise the option.
 Operating lease costs are recognized on a straight-line basis over the lease term and include interest expense on the lease liability and amortization of the ROU asset. Variable lease costs are expensed as incurred and include maintenance costs and real estate taxes. Lease costs are reported in operating costs and expenses and totaled $ 102 million, $ 131 million and $ 162 million, including $ 19 million, $ 23 million and $ 30 million of variable lease costs in 2023, 2022 and 2021, respectively.

 Variable interest entities
 A VIE is a legal entity that does not have sufficient equity at risk to finance its activities without additional financial support or is structured such that equity investors lack the ability to make significant decisions relating to the entity's operations through voting rights or do not participate in the gains and losses of the entity. The Company consolidates VIEs in which the Company is deemed the primary beneficiary. The primary beneficiary is the entity that has both (1) the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE and (2) the power to direct the activities of the VIE that most significantly affect that entity's economic performance.

 Foreign currency translation
 The local currency of the Company's foreign subsidiaries is deemed to be the functional currency of the country in which these subsidiaries operate. The financial statements of the Company's foreign subsidiaries are translated into U.S. dollars at the exchange rate in effect at the end of a reporting period for assets and liabilities and at average exchange rates during the period for results of operations.
 The unrealized gains and losses from the translation of the net assets are recorded as unrealized foreign currency translation adjustments and included in AOCI. Changes in unrealized foreign currency translation adjustments are included in OCI. Gains and losses from foreign currency transactions are reported in operating costs and expenses and have not been material.
 Earnings per common share
 Basic earnings per common share is computed using the weighted average number of common shares outstanding, including vested unissued participating restricted stock units. Diluted earnings per common share is computed using the weighted average number of common and dilutive potential common shares outstanding.
 For the Company, dilutive potential common shares consist of outstanding stock options and unvested non-participating restricted stock units and contingently issuable performance stock awards. The effect of dilutive potential common shares does not include options with an anti-dilutive effect on earnings per common share because their exercise prices exceed the average market price of Allstate common shares during the period or for which the unrecognized compensation cost would have an anti-dilutive effect.

 Adopted accounting standard
 Accounting for Long-Duration Insurance Contracts Effective January 1, 2023, the Company adopted the Financial Accounting Standards Board ("FASB") guidance revising the accounting for certain long-duration insurance contracts using the modified retrospective approach to the transition date of January 1, 2021.
 Under the new guidance, measurement assumptions, including those for mortality, morbidity and policy lapses, are required to be reviewed at least annually, and updated as appropriate. In addition, reserves under the new guidance are required to be discounted using an upper-medium grade fixed income instrument yield that is updated through OCI at each reporting date. Additionally, DAC for all long-duration products are amortized on a simplified basis. Also, the Company's reserve for future policy benefits and DAC are subject to new disclosure guidance.
 In addition, the Company met the conditions included in Accounting Standards Update No. 2022-05, Transition for Sold Contracts, and elected to not apply the new guidance for contracts that were part of the 2021 sales of Allstate Life Insurance Company ("ALIC") and Allstate Life Insurance Company of New York ("ALNY").

 After-tax cumulative effect of change in accounting principle on transition date

 January 1, 2021

 Decrease in retained income
 $

 Decrease in AOCI

 Total decrease in equity
 $

 The decrease in AOCI was primarily attributable to a change in the discount rate used in measuring the reserve for future policy benefits for traditional life contracts and other long-term products with guaranteed terms from a portfolio-based rate at contract issuance to an upper-medium grade fixed income-based rate. The decrease in retained income primarily related to certain cohorts of long-term contracts whose expected net premiums exceeded expected gross premiums which resulted in an increase in reserves and a decrease in retained income equal to the present value of expected future benefits less the present value of expected future premiums at the transition date.

 Transition disclosures The following tables summarize the balance of and changes in the reserve for future policy benefits and DAC on January 1, 2021 upon the adoption of the guidance.

 Pending accounting standards
 Accounting for joint ventures In August 2023, the FASB issued guidance requiring a joint venture to initially measure assets contributed and liabilities assumed at fair value as of the formation date. The new guidance will be applied prospectively for joint ventures with a formation date on or after January 1, 2025. The impact of the adoption is not expected to be material to the Company's results of operations or financial position.
 Segment reporting In November 2023, the FASB issued guidance expanding segment disclosures by requiring disclosure of significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss, an amount and description of its composition for other segment items, and interim disclosures of reportable segments' profit or loss and assets. The guidance is effective for annual periods beginning after December 15, 2023 and interim periods beginning after December 15, 2024 and is to be applied retrospectively, with early adoption permitted. The Company is currently evaluating the impact of adopting the guidance on its disclosures.

 Income tax disclosures In December 2023, the FASB issued guidance enhancing various aspects of income tax disclosures. The guidance now requires a tabular reconciliation between statutory and effective income tax expense (benefit) with both amounts and percentages for a list of required categories. For certain required categories where an individual category is at least five percent of the statutory tax amount, the required category must be further broken out by nature and, for foreign tax effects, jurisdiction. Additionally, entities must disclose income taxes paid, net of refunds received, broken out between federal, state and foreign, and amounts paid, net of refunds received, to an individual jurisdiction when five percent or more of the total income taxes paid, net of refunds received.
 All disclosure requirements in the guidance are annual in nature, and the guidance is effective for annual reporting periods beginning after December 15, 2024, with early adoption permitted. The guidance only affects disclosures and will have no impact on the Company's consolidated financial statements. The Company is currently evaluating the impact of adopting the guidance on its disclosures.

 Note 3
 Dispositions

 Life and annuity business On October 1, 2021, the Company closed the sale of Allstate Life Insurance Company of New York ("ALNY") to Wilton Reassurance Company for $ 400 million. On November 1, 2021, the Company closed the sale of Allstate Life Insurance Company ("ALIC") and certain affiliates to entities managed by Blackstone for total proceeds of $ 4 billion, including a pre-close dividend of $ 1.25 billion paid by ALIC.
 In connection with the sale of ALIC and certain affiliates, the sale agreement included a provision related to contingent consideration that may be earned over a ten-year period with the first potential payment date commencing on January 1, 2026 and a final potential payment date of January 1, 2035. The contingent consideration is determined annually based on the average ten-year Treasury rate over the preceding three-year period compared to a designated rate. The contingent consideration meets the definition

 of a derivative and is accounted for on a fair value basis with periodic changes in fair value reflected in earnings. There are no collateral requirements related to the contingent consideration. See Note 7 for further details.
 In 2021, the loss on disposition was $ 4.09 billion, after-tax, and reflects purchase price adjustments associated with certain pre-close transactions specified in the stock purchase agreements, changes in statutory capital and surplus prior to the closing date and the closing date equity of the sold entities determined under GAAP, excluding AOCI derecognized related to the dispositions.

 Beginning in the first quarter of 2021, the assets and liabilities of the business were reclassified as held for sale and results are presented as discontinued operations. This change was applied on a retrospective basis.

 Reportable Segments

 The Company's chief operating decision maker reviews financial performance and makes decisions about the allocation of resources for the five reportable segments. These segments are described below and align with the Company's key product and service offerings.
 Allstate Protection principally offers private passenger auto and homeowners insurance in the United States and Canada, with earned premiums accounting for 84.8 % of Allstate's 2023 consolidated revenues. Allstate Protection primarily operates in the U.S. (all 50 states and the District of Columbia ("D.C.")) and Canada. For 2023, the top geographic locations for statutory direct premiums for the Allstate Protection segment were Texas, California, New York and Florida. No other jurisdiction accounted for more than 5 % of statutory direct premiums for Allstate Protection. Revenues from external customers generated outside

 the United States were $ 2.06 billion, $ 1.94 billion and $ 1.86 billion in 2023, 2022 and 2021, respectively.
 Run-off Property-Liability includes results from property and casualty insurance coverage that primarily relates to policies written during the 1960s through the mid-1980s. Our exposure to asbestos, environmental and other run-off lines claims arises principally from direct excess commercial insurance, assumed reinsurance coverage, direct primary commercial insurance and other businesses in run-off.
 Protection Services comprise Allstate Protection Plans, Allstate Dealer Services, Allstate Roadside, Arity and Allstate Identity Protection. Protection Services offer consumer product protection plans, protection and insurance products (including vehicle service contracts, guaranteed asset protection, road hazard tire and wheel and paintless dent repair protection), roadside assistance, device and mobile data collection

 The Allstate Corporation 119

 services and analytic solutions using automotive telematics information, identity theft protection and remediation services. Protection Services primarily operates in the U.S. and Canada, with Allstate Protection Plans also offering services in Europe, Australia and Asia. Revenues from external customers generated outside the United States were $ 346 million, $ 258 million and $ 232 million in 2023, 2022 and 2021, respectively and relate to consumer product protection plans sold primarily in the European Union and Australia.
 Allstate Health and Benefits offers employer voluntary benefits, group health and individual health products, including life, accident, critical illness, hospital indemnity, short-term disability and other health products. Allstate Health and Benefits primarily operates in the U.S. (all 50 states and D.C.) and Canada. For 2023, the top geographic locations for statutory direct accident, health and life insurance premiums were Florida, Texas, and Georgia. No other jurisdiction accounted for more than 5 % of statutory direct accident, health and life insurance premiums. Revenues from external customers generated outside the United States relate to voluntary accident and health insurance sold in Canada and were not material.
 Corporate and Other comprises debt service, other holding company activities and certain non-insurance operations, including expenses associated with strategic initiatives, such as the Avail peer-to-peer car-sharing initiative.
 Allstate Protection and Run-off Property-Liability segments comprise Property-Liability. The Company does not allocate investment income, net gains and losses on investments and derivatives, or assets to the Allstate Protection and Run-off Property-Liability segments. Management reviews assets at the Property-Liability, Protection Services, Allstate Health and Benefits, and Corporate and Other levels for decision-making purposes.
 The accounting policies of the reportable segments are the same as those described in Note 2. The effects of intersegment transactions are eliminated in the consolidated results. For segment results, services provided by Protection Services to Allstate Protection are not eliminated as management considers those transactions in assessing the results of the respective segments.

 Measuring segment profit or loss
 The measure of segment profit or loss used in evaluating performance is underwriting income for the Allstate Protection and Run-off Property-Liability and adjusted net income for the Protection Services, Allstate Health and Benefits and Corporate and Other segments.
 Underwriting income is calculated as premiums earned and other revenue, less claims and claims expenses ("losses"), Shelter-in-Place Payback expense, amortization of DAC, operating costs and expenses, amortization or impairment of purchased intangibles and restructuring and related charges as determined using GAAP.
 Adjusted net income is net income (loss) applicable to common shareholders, excluding:

 •

 Interest expense is primarily incurred in the Corporate and Other segment. Capital expenditures for long-lived assets are generally made in Property-Liability as the Company does not allocate assets to the Allstate Protection and Run-off Property-Liability segments. A portion of these long-lived assets are used by entities included in the Protection Services, Allstate Health and Benefits and Corporate and Other segments and, accordingly, are charged to expenses in proportion to their use.

 Limited partnership interests include interests in private equity funds, real estate funds and other funds. Principal factors influencing carrying value appreciation or decline include operating performance, comparable public company earnings multiples, capitalization rates and the economic environment. For equity method limited partnerships, the Company recognizes an impairment loss when evidence demonstrates that the loss is other than temporary. Evidence of a loss in value that is other than temporary may include the absence of an ability to recover the carrying amount of the investment or the inability of the investee to sustain a level of earnings that would justify the carrying amount of the investment. Changes in fair value limited partnerships are recorded through net investment income and therefore are not tested for impairment.

 Portfolio monitoring and credit losses
 Fixed income securities The Company has a comprehensive portfolio monitoring process to identify and evaluate each fixed income security that may require a credit loss allowance.
 For each fixed income security in an unrealized loss position, the Company assesses whether management with the appropriate authority has made the decision to sell or whether it is more likely than not the Company will be required to sell the security before recovery of the amortized cost basis for reasons such as liquidity, contractual or regulatory purposes. If a security meets either of these criteria, any existing credit loss allowance would be written-off against the amortized cost basis of the asset along with any remaining unrealized losses, with incremental losses recorded in earnings.
 If the Company has not made the decision to sell the fixed income security and it is not more likely than not the Company will be required to sell the fixed income security before recovery of its amortized cost basis, the Company evaluates whether it expects to receive cash flows sufficient to recover the entire amortized cost basis of the security. The Company calculates the estimated recovery value based on the best estimate of future cash flows considering past events, current conditions and reasonable and supportable forecasts. The estimated future cash flows are discounted at the security's current effective rate and is compared to the amortized cost of the security.
 The determination of cash flow estimates is inherently subjective, and methodologies may vary depending on facts and circumstances specific to the security. All reasonably available information relevant to the collectability of the security is considered when developing the estimate of cash flows expected to be collected. That information generally includes, but is not limited to, the remaining payment terms of the security, prepayment speeds, the financial condition and future earnings potential of the issue or issuer, expected defaults, expected recoveries, the value of underlying collateral, origination vintage year, geographic concentration of underlying collateral, available reserves or escrows, current subordination levels, third-party guarantees and other credit enhancements. Other information, such as industry analyst reports and forecasts, credit ratings, financial condition of the bond insurer for insured fixed income securities, and other market data relevant to the realizability of contractual cash flows, may also be considered. The estimated fair value of collateral will be used to estimate recovery value if the Company determines that the security is dependent on the liquidation of collateral for ultimate settlement.

 If the Company does not expect to receive cash flows sufficient to recover the entire amortized cost basis of the fixed income security, a credit loss allowance is recorded in earnings for the shortfall in expected cash flows; however, the amortized cost, net of the credit loss allowance, may not be lower than the fair value of the security. The portion of the unrealized loss related to factors other than credit remains classified in AOCI. If the Company determines that the fixed income security does not have sufficient cash flow or other information to estimate a recovery value for the security, the Company may conclude that the entire decline in fair value is deemed to be credit related and the loss is recorded in earnings.
 When a security is sold or otherwise disposed or when the security is deemed uncollectible and written off, the Company removes amounts previously recognized in the credit loss allowance. Recoveries after write-offs are recognized when received. Accrued interest excluded from the amortized cost of fixed income securities totaled $ 495 million and $ 389 million as of December 31, 2023, and 2022, respectively, and is reported within the accrued investment income line of the Consolidated Statements of Financial Position. The Company monitors accrued interest and writes off amounts when they are not expected to be received.
 The Company's portfolio monitoring process includes a quarterly review of all securities to identify instances where the fair value of a security compared to its amortized cost is below internally established thresholds. The process also includes the monitoring of other credit loss indicators such as ratings, ratings downgrades and payment defaults. The securities identified, in addition to other securities for which the Company may have a concern, are evaluated for potential credit losses using all reasonably available information relevant to the collectability or recovery of the security. Inherent in the Company's evaluation of credit losses for these securities are assumptions and estimates about the financial condition and future earnings potential of the issue or issuer. Some of the factors that may be considered in evaluating whether a decline in fair value requires a credit loss allowance are: 1) the financial condition, near-term and long-term prospects of the issue or issuer, including relevant industry specific market conditions and trends, geographic location and implications of rating agency actions and offering prices; 2) the specific reasons that a security is in an unrealized loss position, including overall market conditions which could affect liquidity; and 3) the extent to which the fair value has been less than amortized cost.

 (3)Below investment grade fixed income securities include $ 25 million that have been in an unrealized loss position for a period of twelve or more consecutive months.
 (4)Evaluated based on factors such as discounted cash flows and the financial condition and near-term and long-term prospects of the issue or issuer and were determined to have adequate resources to fulfill contractual obligations.
 Investment grade is defined as a security having a National Association of Insurance Commissioners ("NAIC") designation of 1 or 2, which is comparable to a rating of Aaa, Aa, A or Baa from Moody's or AAA, AA, A or BBB from S&P Global Ratings ("S&P"), or a comparable internal rating if an externally provided rating is not available. Market prices for certain securities may have credit spreads which imply higher or lower credit quality than the current third-party rating. Unrealized losses on investment grade securities are principally related to an increase in market yields which may include increased risk-free interest rates or wider credit spreads since the time of initial purchase. The unrealized losses are expected to reverse as the securities approach maturity.
 ABS in an unrealized loss position were evaluated based on actual and projected collateral losses relative to the securities' positions in the respective securitization trusts, security specific expectations of cash flows, and credit ratings. This evaluation also takes into consideration credit enhancement, measured in terms of (i) subordination from other classes of securities in the trust that are contractually obligated to absorb losses before the class of security the Company owns, and (ii) the expected impact of other structural features embedded in the securitization trust beneficial to the class of securities the Company owns, such as overcollateralization and excess spread. Municipal bonds in an unrealized loss position were evaluated based on the underlying credit quality of the primary obligor, obligation type and quality of the underlying assets.
 As of December 31, 2023, the Company has not made the decision to sell and it is not more likely than not the Company will be required to sell fixed income securities with unrealized losses before recovery of the amortized cost basis.

 Loans The Company establishes a credit loss allowance for mortgage loans and bank loans when they are originated or purchased, and for unfunded commitments unless they are unconditionally cancellable by the Company. The Company uses a probability of default and loss given default model for mortgage loans and bank loans to estimate current expected credit losses that considers all relevant information available including past events, current conditions, and reasonable and supportable forecasts over the life of an asset. The Company also considers such factors as historical losses, expected prepayments and various economic factors. For mortgage loans the Company considers origination vintage year and property level information such as debt service coverage, property type, property location and collateral value. For bank loans the Company considers the credit rating of the borrower, credit spreads and type of loan. After the reasonable and supportable forecast period, the Company's model reverts to historical loss trends.
 Loans are evaluated on a pooled basis when they share similar risk characteristics. The Company monitors loans through a quarterly credit monitoring process to determine when they no longer share similar risk characteristics and are to be evaluated individually when estimating credit losses.
 Loans are written off against their corresponding allowances when there is no reasonable expectation of recovery. If a loan recovers after a write-off, the estimate of expected credit losses includes the expected recovery.
 Accrual of income is suspended for loans that are in default or when full and timely collection of principal and interest payments is not probable. Accrued income receivable is monitored for recoverability and when not expected to be collected is written off through net investment income. Cash receipts on loans on non-accrual status are generally recorded as a reduction of amortized cost.

 The Allstate Corporation 131

 Accrued interest is excluded from the amortized cost of loans and is reported within the accrued investment income line of the Consolidated Statements of Financial Position.

 Bank Loans

 Mortgage loans When it is determined a mortgage loan shall be evaluated individually, the Company uses various methods to estimate credit losses on individual loans such as using collateral value less estimated costs to sell where applicable, including when foreclosure is probable or when repayment is expected to be provided substantially through the operation or sale of the collateral and the borrower is experiencing financial difficulty. When collateral value is used, the mortgage loans may not have a credit loss allowance when the fair value of the collateral exceeds the loan's

 amortized cost. An alternative approach may be utilized to estimate credit losses using the present value of the loan's expected future repayment cash flows discounted at the loan's current effective interest rate.
 Individual loan credit loss allowances are adjusted for subsequent changes in the fair value of the collateral less costs to sell, when applicable, or present value of the loan's expected future repayment cash flows.
 Debt service coverage ratio is considered a key credit quality indicator when mortgage loan credit loss allowances are estimated. Debt service coverage ratio represents the amount of estimated cash flow from the property available to the borrower to meet principal and interest payment obligations. Debt service coverage ratio estimates are updated annually or more frequently if conditions are warranted based on the Company's credit monitoring process.

 Mortgage loans with a debt service coverage ratio below 1.0 that are not considered impaired primarily relate to instances where the borrower has the financial capacity to fund the revenue shortfalls from the properties for the foreseeable term, the decrease in cash flows from the properties is considered

 temporary, or there are other risk mitigating circumstances such as additional collateral, escrow balances or borrower guarantees. Payments on all mortgage loans were current as of December 31, 2023, 2022 and 2021.

 Bank loans When it is determined a bank loan shall be evaluated individually, the Company uses various methods to estimate credit losses on individual loans such as the present value of the loan's expected future repayment cash flows discounted at the loan's current effective interest rate.

 Credit ratings of the borrower are considered a key credit quality indicator when bank loan credit loss allowances are estimated. The ratings are either received from the Securities Valuation Office of the NAIC based on availability of applicable ratings from rating agencies on the NAIC credit rating provider list or a comparable internal rating. The year of origination is determined to be the year in which the asset is acquired.

 Note 6
 Fair Value of Assets and Liabilities

 Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The hierarchy for inputs used in determining fair value maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Assets and liabilities recorded on the Consolidated Statements of Financial Position at fair value are categorized in the fair value hierarchy based on the observability of inputs to the valuation techniques as follows:
 Level 1: Assets and liabilities whose values are based on unadjusted quoted prices for identical assets or liabilities in an active market that the Company can access.
 Level 2: Assets and liabilities whose values are based on the following:
 (a)Quoted prices for similar assets or liabilities in active markets;
 (b)Quoted prices for identical or similar assets or liabilities in markets that are not active; or
 (c)Valuation models whose inputs are observable, directly or indirectly, for substantially the full term of the asset or liability.
 Level 3: Assets and liabilities whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. Unobservable inputs reflect the Company's estimates of the assumptions that market participants would use in valuing the assets and liabilities.
 The availability of observable inputs varies by instrument. In situations where fair value is based on

 internally developed pricing models or inputs that are unobservable in the market, the determination of fair value requires more judgment. The degree of judgment exercised by the Company in determining fair value is typically greatest for instruments categorized in Level 3. In many instances, valuation inputs used to measure fair value fall into different levels of the fair value hierarchy. The category level in the fair value hierarchy is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company uses prices and inputs that are current as of the measurement date, including during periods of market disruption. In periods of market disruption, the ability to observe prices and inputs may be reduced for many instruments.
 The Company is responsible for the determination of fair value and the supporting assumptions and methodologies. The Company gains assurance that assets and liabilities are appropriately valued through the execution of various processes and controls designed to ensure the overall reasonableness and consistent application of valuation methodologies, including inputs and assumptions, and compliance with accounting standards. For fair values received from third parties or internally estimated, the Company's processes and controls are designed to ensure that the valuation methodologies are appropriate and consistently applied, the inputs and assumptions are reasonable and consistent with the objective of determining fair value, and the fair values are accurately recorded. For example, on a continuing basis, the Company assesses the reasonableness of individual fair values that have stale security prices or that exceed certain thresholds as compared to previous fair values received from valuation service providers or brokers or derived from internal models.

 The Allstate Corporation 133

 The Company performs procedures to understand and assess the methodologies, processes and controls of valuation service providers. In addition, the Company may validate the reasonableness of fair values by comparing information obtained from valuation service providers or brokers to other third-party valuation sources for selected securities. The Company performs ongoing price validation procedures such as back-testing of actual sales, which corroborate the various inputs used in internal models to market observable data. When fair value determinations are expected to be more variable, the Company validates them through reviews by members of management who have relevant expertise and who are independent of those charged with executing investment transactions.
 The Company has two types of situations where investments are classified as Level 3 in the fair value hierarchy:
 (1)Specific inputs significant to the fair value estimation models are not market observable. This primarily occurs in the Company's use of broker quotes to value certain securities where the inputs have not been corroborated to be market observable, and the use of valuation models that use significant non-market observable inputs.
 (2)Quotes continue to be received from independent third-party valuation service providers and all significant inputs are market observable; however, there has been a significant decrease in the volume and level of activity for the asset when compared to normal market activity such that the degree of market observability has declined to a point where categorization as a Level 3 measurement is considered appropriate. The indicators considered in determining whether a significant decrease in the volume and level of activity for a specific asset has occurred include the level of new issuances in the primary market, trading volume in the secondary market, the level of credit spreads over historical levels, applicable bid-ask spreads, and price consensus among market participants and other pricing sources.
 Certain assets are not carried at fair value on a recurring basis, including mortgage loans, bank loans, real estate and policy loans and are only included in the fair value hierarchy disclosure when the individual investment is reported at fair value.
 In determining fair value, the Company principally uses the market approach which generally utilizes market transaction data for the same or similar instruments. To a lesser extent, the Company uses the income approach which involves determining fair values from discounted cash flow methodologies. For the majority of Level 2 and Level 3 valuations, a combination of the market and income approaches is used.

 Summary of significant inputs and valuation techniques for Level 2 and Level 3 assets and liabilities measured at fair value on a recurring basis
 Level 2 measurements
 • Fixed income securities:
 U.S. government and agencies, municipal, corporate - public and foreign government: The primary inputs to the valuation include quoted prices for identical or similar assets in markets that are not active, contractual cash flows, benchmark yields and credit spreads.
 Corporate - privately placed: Privately placed are valued using a discounted cash flow model that is widely accepted in the financial services industry and uses market observable inputs and inputs derived principally from, or corroborated by, observable market data. The primary inputs to the discounted cash flow model include an interest rate yield curve, as well as published credit spreads for similar assets in markets that are not active that incorporate the credit quality and industry sector of the issuer.
 Corporate - privately placed also includes redeemable preferred stock that are valued using quoted prices for identical or similar assets in markets that are not active, contractual cash flows, benchmark yields, underlying stock prices and credit spreads.
 ABS: The primary inputs to the valuation include quoted prices for identical or similar assets in markets that are not active, contractual cash flows, benchmark yields, collateral performance, and credit spreads. Certain ABS are valued based on non-binding broker quotes whose inputs have been corroborated to be market observable. Residential mortgage-backed securities, included in ABS, use prepayment speeds as a primary input for valuation.
 • Equity securities: The primary inputs to the valuation include quoted prices or quoted net asset values for identical or similar assets in markets that are not active.
 • Short-term: The primary inputs to the valuation include quoted prices for identical or similar assets in markets that are not active, contractual cash flows, benchmark yields and credit spreads.
 • Other investments: Free-standing exchange listed derivatives that are not actively traded are valued based on quoted prices for identical instruments in markets that are not active.
 Over-the-counter ("OTC") derivatives, including interest rate swaps, foreign currency swaps, total return swaps, foreign exchange forward contracts, certain options and certain credit default swaps, are valued using models that rely on inputs such as interest rate yield curves, implied volatilities, index price levels, currency rates, and credit spreads that are observable for substantially the full term of the contract. The valuation techniques underlying the

 134 www.allstate.com

 models are widely accepted in the financial services industry and do not involve significant judgment.
 Level 3 measurements
 • Fixed income securities:
 Municipal: Comprise municipal bonds that are not rated by third-party credit rating agencies. The primary inputs to the valuation of these municipal bonds include quoted prices for identical or similar assets that are not market observable, contractual cash flows, benchmark yields and credit spreads. Also included are municipal bonds valued based on non-binding broker quotes where the inputs have not been corroborated to be market observable and municipal bonds in default valued based on the present value of expected cash flows.
 Corporate - public and privately placed and ABS: Primarily valued based on non-binding broker quotes where the inputs have not been corroborated to be market observable. Other inputs for corporate fixed income securities include an interest rate yield curve, as well as published credit spreads for similar assets that incorporate the credit quality and industry sector of the issuer.
 • Equity securities: The primary inputs to the valuation include quoted prices or quoted net asset values for identical or similar assets that are not market observable.
 • Short-term: For certain short-term investments, amortized cost is used as the best estimate of fair value.
 • Other investments: Certain OTC derivatives, such as interest rate caps, certain credit default swaps and certain options (including swaptions), are valued using models that are widely accepted in the financial services industry. These are categorized as Level 3 as a result of the significance of non-market observable inputs such as volatility. Other primary inputs include interest rate yield curves and credit spreads and quoted prices for identical or similar assets in markets that exhibit less liquidity relative to those markets supporting Level 2 fair value measurements.

 • Other assets: Includes the contingent consideration provision in the sale agreement for ALIC which meets the definition of a derivative. This derivative is valued internally using a model that includes stochastically determined cash flows and inputs that include spot and forward interest rates, volatility, corporate credit spreads and a liquidity discount. This derivative is categorized as Level 3 due to the significance of non-market observable inputs.
 • Assets held for sale: Comprise municipal, corporate and ABS fixed income securities and equity securities. The valuation is based on the respective asset type as described above.
 • Liabilities held for sale: Comprise derivatives embedded in certain life and annuity contracts which are valued internally using models widely accepted in the financial services industry that determine a single best estimate of fair value for the embedded derivatives within a block of contractholder liabilities. The models primarily use stochastically determined cash flows based on the contractual elements of embedded derivatives, projected option cost and applicable market data, such as interest rate yield curves and equity index volatility assumptions. These are categorized as Level 3 as a result of the significance of non-market observable inputs.
 Assets measured at fair value on a non-recurring basis
 Comprise long-lived assets to be disposed of by sale, including real estate, that are written down to fair value less costs to sell and bank loans written down to fair value in connection with recognizing credit losses.
 Investments excluded from the fair value hierarchy
 Limited partnerships carried at fair value, which do not have readily determinable fair values, use NAV provided by the investees and are excluded from the fair value hierarchy. These investments are generally not redeemable by the investees and generally cannot be sold without approval of the general partner. The Company receives distributions of income and proceeds from the liquidation of the underlying assets of the investees, which usually takes place in years 4-9 of the typical contractual life of 10 - 12 years. As of December 31, 2023, the Company has commitments to invest $ 175 million in these limited partnership interests.

 As of December 31, 2023 and 2022, Level 3 fair value measurements of fixed income securities total $ 153 million and $ 173 million, respectively, and include $ 26 million and $ 70 million, respectively, of securities valued based on non-binding broker quotes where the inputs have not been corroborated to be market observable and $ 11 million and $ 21 million, respectively, of municipal fixed income securities that are not rated

 by third-party credit rating agencies. An increase (decrease) in credit spreads for fixed income securities valued based on non-binding broker quotes would result in a lower (higher) fair value, and an increase (decrease) in the credit rating of municipal bonds that are not rated by third-party credit rating agencies would result in a higher (lower) fair value.

 Transfers into Level 3 during 2022 and 2021 included situations where a quote was not provided by the Company's independent third-party valuation service provider and as a result the price was stale or had been replaced with a broker quote where the inputs had not been corroborated to be market observable resulting in the security being classified as Level 3.

 There were no transfers out of Level 3 during 2023. Transfers out of Level 3 during 2022 and 2021 included situations where a broker quote was used in the prior period and a quote became available from the Company's independent third-party valuation service provider in the current period. A quote utilizing the new pricing source was not available as of the prior period, and any gains or losses related to the change in valuation source for individual securities were not significant.

 Note 7
 Derivative Financial Instruments and Off-balance Sheet Financial Instruments

 The Company uses derivatives for risk reduction and to increase investment portfolio returns through asset replication. Risk reduction activity is focused on managing the risks with certain assets and liabilities arising from the potential adverse impacts from changes in risk-free interest rates, changes in equity market valuations, increases in credit spreads and foreign currency fluctuations.
 Asset replication refers to the "synthetic" creation of assets through the use of derivatives. The Company replicates fixed income securities using a combination of a credit default swap, index total return swap, options, futures, or a foreign currency forward contract and one or more highly rated fixed income securities, primarily investment grade host bonds, to synthetically replicate the economic characteristics of one or more cash market securities. The Company replicates equity securities using futures, index total return swaps, and options to increase equity exposure.
 Property-Liability may use interest rate swaps, swaptions, futures and options to manage the interest rate risks of existing investments. These instruments are utilized to change the duration of the portfolio in order to offset the economic effect that interest rates would otherwise have on the fair value of its fixed income securities. Fixed income index total return swaps are used to offset valuation losses in the fixed income portfolio during periods of declining market values. Credit default swaps are typically used to mitigate the credit risk within the Property-Liability fixed income portfolio. Equity index total return swaps, futures and options are used by Property-Liability to offset valuation losses in the equity portfolio during periods of declining equity market values. In addition, equity futures are used to hedge the market risk related to deferred compensation liability contracts. Forward contracts are primarily used by Property-Liability to hedge foreign currency risk associated with holding foreign currency denominated investments and foreign operations.
 In 2022, the Company also had a derivative embedded in a non-derivative host contract that was required to be separated from the host contract and accounted for at fair value with changes in fair value of the embedded derivative reported in net income.
 When derivatives meet specific criteria, they may be designated as accounting hedges and accounted for as fair value, cash flow, foreign currency fair value or foreign currency cash flow hedges.
 The notional amounts specified in the contracts are used to calculate the exchange of contractual

 payments under the agreements and are generally not representative of the potential for gain or loss on these agreements. However, the notional amounts specified in credit default swaps where the Company has sold credit protection represent the maximum amount of potential loss, assuming no recoveries.
 Fair value, which is equal to the carrying value, is the estimated amount that the Company would receive or pay to terminate the derivative contracts at the reporting date. The carrying value amounts for OTC derivatives are further adjusted for the effects, if any, of enforceable master netting agreements and are presented on a net basis, by counterparty agreement, in the Consolidated Statements of Financial Position.
 For those derivatives which qualify and have been designated as fair value accounting hedges, net income includes the changes in the fair value of both the derivative instrument and the hedged risk. For cash flow hedges, gains and losses are amortized from AOCI and are reported in net income in the same period the forecasted transactions being hedged impact net income.
 Non-hedge accounting is generally used for "portfolio" level hedging strategies where the terms of the individual hedged items do not meet the strict homogeneity requirements to permit the application of hedge accounting. For non-hedge derivatives, net income includes changes in fair value and accrued periodic settlements, when applicable. With the exception of non-hedge derivatives used for asset replication and non-hedge embedded derivatives, all of the Company's derivatives are evaluated for their ongoing effectiveness as either accounting hedge or non-hedge derivative financial instruments on at least a quarterly basis.
 In connection with the sale of ALIC and certain affiliates in 2021, the sale agreement included a provision related to contingent consideration that may be earned over a ten-year period with the first potential payment date commencing on January 1, 2026 and a final potential payment date of January 1, 2035. The contingent consideration is determined annually based on the average ten-year Treasury rate over the preceding three-year period compared to a designated rate. The contingent consideration meets the definition of a derivative and is accounted for on a fair value basis with periodic changes in fair value reflected in earnings. There are no collateral requirements related to the contingent consideration.

 The Company manages its exposure to credit risk by utilizing highly rated counterparties, establishing risk control limits, executing legally enforceable master netting agreements ("MNAs") and obtaining collateral where appropriate. The Company uses MNAs for OTC derivative transactions that permit either party to net payments due for transactions and collateral is either pledged or obtained when certain predetermined exposure limits are exceeded.

 —

 (1)$ 5 million of collateral was posted under MNAs for contracts containing credit-risk-contingent provisions that are in a liability provision.

 The Company has not incurred any losses on derivative financial instruments due to counterparty nonperformance. Other derivatives, including futures and certain option contracts, are traded on organized exchanges which require margin deposits and guarantee the execution of trades, thereby mitigating any potential credit risk.
 Counterparty credit exposure represents the Company's potential loss if all of the counterparties concurrently fail to perform under the contractual terms of the contracts and all collateral, if any, becomes worthless. This exposure is measured by the fair value of OTC derivative contracts with a positive fair value at the reporting date reduced by the effect, if any, of legally enforceable master netting agreements.

 Market risk is the risk that the Company will incur losses due to adverse changes in market rates and prices. Market risk exists for all of the derivative financial instruments the Company currently holds, as these instruments may become less valuable due to adverse changes in market conditions. To limit this risk, the Company's senior management has established risk control limits. In addition, changes in fair value of the derivative financial instruments that the Company uses for risk management purposes are generally offset by the change in the fair value or cash flows of the hedged risk component of the related assets, liabilities or forecasted transactions.

 Certain of the Company's derivative transactions contain credit-risk-contingent termination events and cross-default provisions. Credit-risk-contingent termination events allow the counterparties to terminate the derivative agreement or a specific trade on certain dates if AIC's financial strength credit ratings by Moody's or S&P fall below a certain level. Credit-risk-contingent cross-default provisions allow the counterparties to terminate the derivative agreement if the Company defaults by pre-determined threshold amounts on certain debt instruments.
 The following table summarizes the fair value of derivative instruments with termination, cross-default or collateral credit-risk-contingent features that are in a liability position, as well as the fair value of assets and collateral that are netted against the liability in accordance with provisions within legally enforceable MNAs.

 In the preceding table, the contractual amounts represent the amount at risk if the contract is fully drawn upon, the counterparty defaults and the value of any underlying security becomes worthless. Unless noted otherwise, the Company does not require

 collateral or other security to support off-balance sheet financial instruments with credit risk.
 Commitments to invest in limited partnership interests represent agreements to acquire new or additional participation in certain limited partnership investments. The Company enters into these

 The Allstate Corporation 145

 agreements in the normal course of business. Because the investments in limited partnerships are not actively traded, it is not practical to estimate the fair value of these commitments.
 Private placement commitments represent commitments to purchase private placement debt and private equity securities at a future date. The Company enters into these agreements in the normal course of business. The fair value of the debt commitments generally cannot be estimated on the date the commitment is made as the terms and conditions of the underlying private placement securities are not yet final. Because the private equity securities are not

 actively traded, it is not practical to estimate fair value of the commitments.
 Other loan commitments are agreements to lend to a borrower provided there is no violation of any condition established in the contract. The Company enters into these agreements to commit to future loan fundings at predetermined interest rates. Unless unconditionally cancellable, the Company recognizes a credit loss allowance on such commitments. Commitments have either fixed or varying expiration dates or other termination clauses. The fair value of these commitments is insignificant.

 Note 8
 Variable Interest Entities

 Consolidated VIEs, of which the Company is the primary beneficiary, primarily include Adirondack Insurance Exchange, a New York reciprocal insurer, and New Jersey Skylands Insurance Association, a New Jersey reciprocal insurer (together "Reciprocal Exchanges"). The Reciprocal Exchanges are insurance carriers organized as unincorporated associations. The Company does not own the equity of the Reciprocal Exchanges, which is owned by their respective policyholders.
 The Company manages the business operations of the Reciprocal Exchanges and has the power to direct their activities that most significantly impact their economic performance. The Company receives a management fee for the services provided to the Reciprocal Exchanges. In addition, as of both December 31, 2023 and 2022, the Company holds interests of $ 123 million in the form of surplus notes included in other liabilities and expenses on the Statement of Assets and Liabilities of the Reciprocal Exchanges that provide capital to the Reciprocal Exchanges and would absorb any expected losses.

 The Company is therefore the primary beneficiary. In addition, the Company provides quota share reinsurance to the Reciprocal Exchanges.
 In the event of dissolution, policyholders would share any residual unassigned surplus but are not subject to assessment for any deficit in unassigned surplus of the Reciprocal Exchanges. The assets of the Reciprocal Exchanges can be used only to settle the obligations of the Reciprocal Exchanges and general creditors have no recourse to the Company.
 The results of operations of the Reciprocal Exchanges are included in the Company's Allstate Protection segment and generated $ 224 million, $ 164 million and $ 181 million of earned premiums in 2023, 2022 and 2021, respectively.
 Total costs and expenses were $ 251 million, $ 244 million and $ 248 million in 2023, 2022 and 2021, respectively.

 Nonconsolidated VIEs The Company makes investments in limited partnership interests and other alternative investments that may be issued by VIEs. These investments are generally accounted for under the equity method and are reported as limited partnership interests in the Company's Consolidated Statements of Financial Position. The Company does

 not take an active role in management of these investments. Therefore, the Company has determined it is not the primary beneficiary as it has no ability to direct activities that could significantly affect the economic performance of the investments. The Company's maximum exposure to loss is limited to the investment carrying value and any unfunded

 146 www.allstate.com

 commitments. Neither the Company's carrying amounts nor the unfunded commitments related to these VIEs are material individually or in the aggregate.
 In addition, the Company makes investments in structured securities issued by VIEs for which the Company is not the investment manager. These structured investments typically invest in fixed income securities and are managed by third parties and include ABS and collateralized debt obligations. The Company has not provided financial or other support other than its original investment. For these investments, the Company determined it is not the primary beneficiary due to the relative size of the

 Company's investment in comparison to the principal amount of the structured securities issued by the VIEs, the Company's inability to direct the activities that most significantly impact the economic performance of the VIEs, and, where applicable, the level of credit subordination which reduces the Company's obligation to absorb losses or right to receive benefits. The Company's maximum exposure to loss on these investments is limited to the amount of the Company's investment. Neither the Company's carrying amounts nor the unfunded commitments related to these VIEs are material individually or in the aggregate.

 Note 9
 Reserve for Property and Casualty Insurance Claims and Claims Expense

 The Company establishes reserves for claims and claims expense on reported and unreported claims of insured losses. The Company's reserving process considers known facts and interpretations of circumstances and factors including the Company's experience with similar cases, actual claims paid, historical trends involving claim payment patterns and pending levels of unpaid claims, loss management programs, product mix and contractual terms, changes in laws and regulations, judicial decisions, and economic conditions.
 When the Company experiences changes in the mix or type of claims or changing claim settlement patterns or data, it applies actuarial judgment in the determination and selection of development factors to develop reserve liabilities. Supply chain disruptions and inflation have resulted in higher part costs, used car values and longer time to claim resolution, which have combined with labor shortages to increase physical damage loss costs. Medical inflation, treatment trends, attorney representation, litigation costs and more severe accidents have contributed to higher third-party bodily injury loss costs. The Company has also digitized and modified claim processes to increase effectiveness and efficiency. These factors may lead to historical development trends being less predictive of future loss development, potentially creating additional reserve variability. Generally, the initial reserves for a new accident year are established based on claim frequency and severity assumptions for different business segments, lines and coverages based on historical relationships to relevant inflation indicators. Reserves for prior accident years are statistically determined using several different actuarial estimation methods. Changes in auto claim frequency may result from changes in mix of business, driving behaviors, miles driven or other factors. Changes in auto current year claim severity are generally influenced by inflation in the medical and auto repair sectors, the effectiveness and efficiency of claim settlements and changes in mix of claim types. When changes in claim data occur, actuarial judgment is used to determine appropriate development factors to establish reserves. The Company's reserving process incorporates changes in loss patterns, operational statistics and changes in claims reporting processes to determine its best estimate of recorded reserves.

 As part of the reserving process, the Company may also supplement its claims processes by utilizing third-party adjusters, appraisers, engineers, inspectors, and other professionals and information sources to assess and settle catastrophe and non-catastrophe related claims. The effects of inflation are implicitly considered in the reserving process.
 Because reserves are estimates of unpaid portions of losses that have occurred, including IBNR losses, the establishment of appropriate reserves, including reserves for catastrophes, Run-off Property-Liability and reinsurance and indemnification recoverables, is an inherently uncertain and complex process. The ultimate cost of losses may vary materially from recorded amounts, which are based on management's best estimates.
 The highest degree of uncertainty is associated with reserves for losses incurred in the initial reporting period as it contains the greatest proportion of losses that have not been reported or settled as well as heightened uncertainty for claims that involve litigation or take longer to settle during periods of rapidly increasing loss costs. The Company also has uncertainty in the Run-off Property-Liability reserves that are based on events long since passed and are complicated by lack of historical data, legal interpretations, unresolved legal issues and legislative intent based on establishment of facts.
 The Company regularly updates its reserve estimates as new information becomes available and as events unfold that may affect the resolution of unsettled claims. Changes in reserve estimates, which may be material, are reported in property and casualty insurance claims and claims expense in the Consolidated Statements of Operations in the period such changes are determined.
 Management believes that the reserve for property and casualty insurance claims and claims expense, net of recoverables, is appropriately established in the aggregate and adequate to cover the ultimate net cost of reported and unreported claims arising from losses which had occurred by the date of the Consolidated Statements of Financial Position based on available facts, laws and regulations.

 Incurred claims and claims expense represents the sum of paid losses, claim adjustment expenses and reserve changes in the calendar year. This expense includes losses from catastrophes of $ 5.64 billion, $ 3.11 billion and $ 3.34 billion in 2023, 2022 and 2021, respectively, net of recoverables. Catastrophes are an inherent risk of the property and casualty insurance business that have contributed to, and will continue to contribute to, material year-to-year fluctuations in the Company's results of operations and financial position.

 The Company calculates and records a single best reserve estimate for losses from catastrophes, in conformance with generally accepted actuarial standards. As a result, management believes that no other estimate is better than the recorded amount. Due to the uncertainties involved, including the factors described above, the ultimate cost of losses may vary materially from recorded amounts, which are based on management's best estimates.

 Significant assumptions To determine mortality and morbidity assumptions, the Company uses a combination of its historical experience and industry data. Mortality and morbidity are monitored throughout the year. Historical experience is obtained through annual Company experience studies in the third quarter that consider its historical claim patterns. The lapse assumption is determined based on historical lapses of the Company's insurance contracts.
 The Company's annual review of the mortality, morbidity and lapse experience assumptions in 2023, 2022, and 2021 resulted in an increase of less than $1 million, a decrease of $ 4 million and a decrease of $ 11 million respectively, to the reserve for future policy benefits.
 The following table summarizes the ratio of actual to expected experience used in the determination of the reserve for future policy benefits.

 The Allstate Corporation 159

 Property and casualty reinsurance and indemnifications recoverables
 Property and casualty programs are grouped by the following characteristics:
 1.Indemnification programs - industry pools, facilities or associations that are governed by state insurance statutes or regulations or the federal government.
 2.Catastrophe reinsurance programs - reinsurance protection for catastrophe exposure nationwide and by specific states, as applicable.
 3.Other reinsurance programs - reinsurance protection for asbestos, environmental and other liability exposures as well as commercial lines, including shared economy.
 Property and casualty reinsurance is in place for the Allstate Protection, Run-off lines and Protection Services segments. The Company purchases reinsurance after evaluating the financial condition of the reinsurer as well as the terms and price of coverage.
 Indemnification programs The Company participates in state-based industry pools or facilities mandating participation by insurers offering certain coverage in their state, including the Michigan Catastrophic Claims Association ("MCCA"), the New Jersey Property-Liability Insurance Guaranty Association ("PLIGA"), the North Carolina Reinsurance Facility ("NCRF") and the Florida Hurricane Catastrophe Fund ("FHCF"). When the Company pays qualifying claims under the coverage indemnified by a state's pool or facility, the Company is reimbursed for the qualifying claim losses and expenses. Each state pool or facility may assess participating companies to collect sufficient amounts to meet its total indemnification requirements. The enabling legislation for each state's pool or facility compels the pool or facility only to indemnify participating companies for qualifying claim losses and expenses; the state pool or facility does not underwrite the coverage or take on the ultimate risk of the indemnified business. As a pass through, these pools or facilities manage the receipt of assessments paid by participating companies and payment of indemnified amounts for covered claims presented by participating companies. The Company has not had any credit losses related to these indemnification programs.
 State-based industry pools or facilities
 Michigan Catastrophic Claims Association The MCCA is a statutory indemnification mechanism for member insurers' qualifying personal injury protection claims paid for the unlimited lifetime medical benefits above the applicable retention level for qualifying injuries from automobile, motorcycle and commercial vehicle accidents. Indemnification recoverables on paid and unpaid claims, including IBNR, as of December 31, 2023 and 2022 include $ 6.42 billion and $ 6.72 billion, respectively, from the MCCA for its indemnification obligation.

 The MCCA is funded by annually assessing participating member companies actively writing motor vehicle coverage in Michigan on a per vehicle basis that is currently $ 122 per vehicle insured for unlimited personal injury protection ("PIP") coverage and $ 48 per vehicle for other PIP coverage. The MCCA's calculation of the annual assessment is based upon the total of members' actuarially determined present value of expected payments on lifetime claims by all persons expected to be catastrophically injured in that year and ultimately qualify for MCCA reimbursement, its operating expenses, and adjustments for the amount of excesses or deficiencies in prior assessments. The assessment is incurred by the Company as policies are written and recovered as a component of premiums from the Company's customers.
 The MCCA indemnifies qualifying claims of all current and former member companies (whether or not actively writing motor vehicle coverage in Michigan) for qualifying claims and claims expenses incurred while the member companies were actively writing the mandatory PIP coverage in Michigan. Member companies actively writing automobile coverage in Michigan include the MCCA annual assessments in determining the level of premiums to charge insureds in the state.
 As required for member companies by the MCCA, the Company reports covered paid and unpaid claims to the MCCA when estimates of loss for a reported claim are expected to exceed the retention level, the claims involve certain types of severe injuries, or there are litigation demands received suggesting the claim value exceeds certain thresholds. The retention level is adjusted upward every other MCCA fiscal year by the lesser of 6 % or the increase in the consumer price index. The retention level is $ 635 thousand per claim for the fiscal two-years ending June 30, 2025 compared to $ 600 thousand per claim for the fiscal two-years ending June 30, 2023.
 The MCCA is obligated to fund the ultimate liability of member companies' qualifying claims and claim expenses. The MCCA does not underwrite the insurance coverage or hold any underwriting risk.
 The MCCA indemnifies members as qualifying claims are paid and billed by members to the MCCA. Unlimited lifetime covered losses result in significant levels of ultimate incurred claim reserves being recorded by member companies along with offsetting indemnification recoverables. Disputes with claimants over coverage on certain reported claims can result in additional losses, which may be recoverable from the MCCA, excluding litigation expenses. There is currently no method by which insurers are able to obtain the benefit of managed care programs to reduce claims costs through the MCCA.
 The MCCA annual assessments fund current operations and member company reimbursements. The MCCA prepares statutory-basis financial statements in conformity with accounting practices prescribed or permitted by the State of Michigan Department of Insurance and Financial Services ("MI

 160 www.allstate.com

 DOI"). The MI DOI has granted the MCCA a statutory permitted practice that expires in June 30, 2025 to discount its liabilities for loss and loss adjustment expense. As of June 30, 2023, the date of its most recent annual financial report, the MCCA had cash and invested assets of $ 21.58 billion and an accumulated deficit of $ 2.05 billion. The permitted practice reduced the accumulated deficit by $ 44.95 billion. As a result of this deficit, the assessment includes an increase of $ 48 per passenger and commercial vehicle and motorcycle insured beginning July 1, 2023, with varying assessments for commercial fleet and historical vehicles.
 New Jersey Property-Liability Insurance Guaranty Association PLIGA serves as the statutory administrator of the Unsatisfied Claim and Judgment Fund ("UCJF"), Workers' Compensation Security Fund and the New Jersey Surplus Lines Insurance Guaranty Fund.
 In addition to its insolvency protection responsibilities, PLIGA reimburses insurers for unlimited excess medical benefits ("EMBs") paid in connection with PIP claims in excess of $ 75,000 for policies issued or renewed prior to January 1, 1991, and limited EMB claims in excess of $ 75,000 and capped at $ 250,000 for policies issued or renewed on or after January 1, 1991, to December 31, 2003.
 A significant portion of the incurred claim reserves and the recoverables can be attributed to a small number of catastrophic claims. Assessments paid to PLIGA for the EMB program totaled $ 7 million in 2023. The amounts of paid and unpaid recoverables as of December 31, 2023 and 2022 were $ 326 million and $ 330 million, respectively.
 PLIGA annually assesses all admitted property and casualty insurers writing covered lines in New Jersey for PLIGA indemnification and expenses. PLIGA assessments may be recouped as a surcharge on premiums collected. PLIGA does not ultimately retain underwriting risk as it assesses member companies for their expected qualifying losses to provide funding for payment of its indemnification obligation to member companies for their actual losses. As a pass through, PLIGA facilitates these transactions of receipt of assessments paid by member companies and payment to member companies for covered claims presented by them for indemnification. As of December 31, 2022, the date of its most recent annual financial report, PLIGA had a fund balance of $ 271 million.
 As statutory administrator of the UCJF, PLIGA provides compensation to qualified claimants for personal injury protection, bodily injury, or death caused by private passenger automobiles operated by uninsured or "hit and run" drivers. The UCJF also provides private passenger pedestrian personal injury protection benefits when no other coverage is available.
 PLIGA annually collects a UCJF assessment from all admitted property and casualty insurers writing motor vehicle liability insurance in New Jersey for UCJF indemnification and expenses. UCJF assessments can

 be expensed as losses recoverable in rates as appropriate. As of December 31, 2022, the date of its most recent annual financial report, the UCJF fund had a balance of $ 71 million.
 North Carolina Reinsurance Facility The NCRF provides automobile liability insurance to drivers that private market insurers are not otherwise willing to insure. All insurers licensed to write automobile insurance in North Carolina are members of the NCRF. Premiums, losses and expenses are assigned to the NCRF. North Carolina law allows the NCRF to recoup operating losses for certain insureds through a surcharge to policyholders. As of September 30, 2023, the NCRF reported a deficit of $ 122 million in members' equity. The NCRF implemented a loss recoupment surcharge on all private passenger and commercial fleet policies effective October 1, 2023, through March 31, 2024. Member companies are assessed the recoupment surcharge. The loss recoupment surcharge will be adjusted on April 1, 2024 and discontinued once losses are recovered. The NCRF results are shared by the member companies in proportion to their respective North Carolina automobile liability writings. For the fiscal year ending September 30, 2023, net gain was $ 25 million, including $ 1.2 billion of earned premiums, $ 364 million of certain private passenger auto risk recoupment and $ 153 million of member loss recoupments. As of December 31, 2023, the NCRF recoverables on paid claims is $ 83 million and recoverables on unpaid claims is $ 299 million. Paid recoverable balances, if covered, are typically settled within sixty days of monthly filing.
 Florida Hurricane Catastrophe Fund Allstate subsidiaries Castle Key Insurance Company ("CKIC") and Castle Key Indemnity Company ("CKI", and together with CKIC, "Castle Key") participate in the mandatory coverage provided by the FHCF and therefore have access to reimbursement for certain qualifying Florida hurricane losses from the FHCF. Castle Key has exposure to assessments and pays annual premiums to the FHCF for this reimbursement protection. The FHCF has the authority to issue bonds to pay its obligations to participating insurers in excess of its capital balances. Payment of these bonds is funded by emergency assessments on all property and casualty premiums in the state, except workers' compensation, medical malpractice, accident and health insurance and policies written under the National Flood Insurance Program ("NFIP"). The FHCF emergency assessments are limited to 6 % of premiums per year beginning the first year in which reimbursements require bonding, and up to a total of 10 % of premiums per year for assessments in the second and subsequent years, if required to fund additional bonding. The FHCF has not issued an emergency assessment since 2015.
 Annual premiums earned and paid under the FHCF agreement were $ 28 million, $ 24 million and $ 15 million in 2023, 2022 and 2021, respectively. Commuted contracts related to Hurricane Irma resulted in payments to the Company of $ 6 million in 2023. Qualifying losses were $ 74 million and $ 13 million in 2022 and 2021, respectively. The Company has access

 The Allstate Corporation 161

 to reimbursement provided by the FHCF for 90 % of qualifying personal property losses that exceed its current retention of $ 152 million for the two largest hurricanes and $ 51 million for other hurricanes, up to a maximum total of $ 312 million, effective from June 1, 2023 to May 31, 2024. The amounts recoverable from the FHCF totaled $ 82 million and $ 96 million as of December 31, 2023 and 2022, respectively.
 Federal Government - National Flood Insurance Program NFIP is a program administered by the Federal Emergency Management Agency ("FEMA") whereby the Company sells and services NFIP flood insurance policies as an agent of FEMA and receives fees for its services. The Company is fully indemnified for claims and claim expenses and does not retain any ultimate risk for the indemnified business. The federal government is obligated to pay all claims and certain allocated loss adjustment expenses in accordance with the arrangement.
 Congressional authorization for the NFIP is periodically evaluated and may be subjected to freezes, including when the federal government experiences a shutdown. FEMA has a NFIP reinsurance program to manage the future exposure of the NFIP through the transfer of risk to private reinsurance companies and capital market investors. Congress is evaluating the funding of the program as well as considering reforms to the program that would be incorporated in legislation to reauthorize the NFIP. As of September 30, 2023, the NFIP owes $ 20.5 billion to the U.S. Treasury.
 The amounts recoverable as of December 31, 2023 and 2022 were $ 76 million and $ 145 million, respectively. Premiums earned under the NFIP include $ 327 million, $ 319 million and $ 350 million in 2023, 2022 and 2021, respectively. Qualifying losses incurred include $ 102 million, $ 435 million and $ 267 million in 2023, 2022 and 2021, respectively.
 Catastrophe reinsurance The Company's reinsurance program is designed to provide reinsurance protection for catastrophes resulting from multiple perils including hurricanes, windstorms, hail, tornadoes, winter storms, wildfires, earthquakes and fires following earthquakes.
 • The Company purchases reinsurance from traditional reinsurance companies as well as the insurance-linked securities ("ILS") market.
 • The majority of the Company's program comprises multi-year contracts, primarily placed in the traditional reinsurance market, such that generally one-third of the program is renewed every year.
 • Coverage is generally purchased on a broad geographic, product line and multiple peril loss basis.
 • Florida personal lines property is covered by a separate agreement, as the risk of loss is different and the Company's subsidiaries operating in this state are separately capitalized.
 • When applicable, reinsurance reinstatement premiums are recognized in the same period as

 the loss event that gave rise to the reinstatement premium and are recorded in claims and claims expense in the consolidated statements of operations.
 The Company's current catastrophe reinsurance program supports the Company's risk and return framework which is intended to provide shareholders with an acceptable return on the risks assumed in the property business, and to reduce variability of earnings, while providing protection to customers. This framework incorporates the Company's robust economic capital model and is informed by catastrophe risk models including hurricanes, earthquakes and wildfires and adjusts based on premium and insured value growth. The Company's reinsurance agreements are part of its capital models and its catastrophe risk management strategy. As of December 31, 2023, the modeled 1-in-100 probable maximum loss for hurricane, earthquake and wildfire perils is approximately $ 2.5 billion, net of reinsurance. The Company continually reviews its aggregate risk appetite and the cost and availability of reinsurance to optimize the risk and return profile of this exposure. The following catastrophe reinsurance agreements are in effect as of December 31, 2023.
 The Nationwide Excess Catastrophe Reinsurance Program (the "Nationwide Program") provides coverage up to $ 6.92 billion of loss less retention of $ 500 million to $ 750 million, and is subject to the percentage of reinsurance placed in each of its agreements. Property business in the state of Florida is excluded from this program. Separate reinsurance agreements address the distinct needs of separately capitalized legal entities. The Nationwide Program includes reinsurance agreements with both the traditional and ILS markets as described below:
 • Core traditional market multi-year and per occurrence excess agreements provide limits totaling $ 4.69 billion for catastrophe losses arising out of multiple perils and are comprised of the following:
 –$ 3.58 billion of placed limits exhausting at $ 4.25 billion, with one annual reinstatement:
 31.6 % of the coverage is provided in four multi-year contracts attaching at $ 500 million.
 31.7 % of the coverage is provided in five multi-year contracts with the first $ 250 million in excess of $ 500 million retained by Allstate.
 31.7 % of the coverage is provided in one single-year contract providing $ 250 million of placed limit in excess of a $ 750 million retention and four multi-year contracts attaching at $ 1.00 billion.
 Three single-year contracts providing coverage between $ 1.75 billion and $ 4.25 billion, 4 % placed.

 162 www.allstate.com

 – Two single-year contracts providing $ 500 million of limits in excess of a $ 4.25 billion retention, one 95 % placed and one 4 % placed.
 –$ 105 million of placed limits in excess of a $ 4.75 billion retention and $ 131 million of placed limits in excess of a $ 5.54 billion retention, both with a 5 % co-participation and one reinstatement of limits over its eight-year term.
 –$ 375 million of placed limits in single-year placements filling capacity around the multi-year and ILS placements:
 One contract providing $ 95 million of placed limits in excess of a $ 4.75 billion retention, with two limits available in any one contract year.
 One contract providing $ 260 million of placed limits in excess of a $ 4.75 billion retention, with no annual reinstatement.
 One contract providing $ 20 million of placed limits in excess of a $ 6.82 billion retention, with no annual reinstatement.
 • ILS placements provide $ 1.80 billion of placed limits, with no reinstatement of limits, and are comprised of the following:
 – Six contracts providing occurrence coverage of $ 1.05 billion of placed limits, reinsuring losses in all states except Florida caused by named storms, earthquakes and fire following earthquakes, severe weather, wildfires, and other naturally occurring or man-made events determined to be a catastrophe by the Company.
 – Three contracts providing occurrence and aggregate coverage of $ 425 million of placed limits, also provide that for each annual period beginning April 1, Allstate declared catastrophes to personal lines property and automobile business can be aggregated to erode the aggregate retention and qualify for coverage under the aggregate limits. Recoveries are limited to the ultimate net loss from the reinsured event.
 – Two contracts, providing aggregate coverage of $ 325 million of placed limits.
 Florida program The Florida program provides coverage for property policies of CKIC and certain affiliate companies for Florida catastrophe events up to $ 1.66 billion of a billion of losses less a $ 40 million retention. The Florida program includes reinsurance agreements placed in the traditional market, the FHCF, the Florida Reinsurance to Assist Policyholders Program ("RAP") and the ILS market as follows:
 • Traditional market placements comprise reinsurance limits for losses to personal lines property in Florida arising out of multiple perils. These contracts provide a combined $ 695 million of limits, with a portion of the traditional market

 placements providing coverage for perils not covered by the FHCF and RAP contracts, which only cover hurricanes.
 • Three FHCF contracts provide $ 330 million of limits for qualifying losses to personal lines property in Florida caused by storms the National Hurricane Center declares to be hurricanes. The three contracts are 90 % placed.
 • Three RAP contracts provide $ 49 million of limits for qualifying losses to personal lines property in Florida caused by storms the National Hurricane Center declares to be hurricanes. The three contracts are 90 % placed.
 • ILS placements provide $ 620 million of reinsurance limits for qualifying losses to personal lines property in Florida caused by a named storm event, a severe weather event, an earthquake event, a fire event, a volcanic eruption event, or a meteorite impact event.
 National General Lender Services Standalone Program is placed in the traditional market and provides $ 255 million of coverage, subject to a $ 60 million retention, with one reinstatement of limits. Inuring contracts include the National General Florida Hurricane Catastrophe Fund contract providing $ 64 million of limits in excess of a $ 33 million retention, 90 % placed, and the National General RAP Contract providing $ 10 million of limits in excess of a $ 24 million retention, 90 % placed.
 National General Reciprocal Excess Catastrophe Reinsurance Contracts are placed in the traditional market and provide $ 600 million of coverage, subject to a $ 20 million retention, with one reinstatement of limits.
 Kentucky Earthquake Excess Catastrophe Reinsurance Contract is placed in the traditional market and provides two limits of $ 28 million, subject to a $ 2 million retention with one reinstatement of limits.
 Canada Catastrophe Excess of Loss Reinsurance Contract is placed in the traditional market and provides CAD 255 million of placed limits, subject to a CAD 75 million retention, with one reinstatement of limits.
 The Company has not experienced credit losses on its catastrophe reinsurance programs. The total cost of the property catastrophe reinsurance program was $ 1.02 billion, $ 788 million and $ 556 million in 2023, 2022 and 2021, respectively.
 Other reinsurance programs The Company's other reinsurance programs relate to commercial lines, including shared economy, and asbestos, environmental, and other liability exposures. The largest reinsurance recoverable balance the Company had outstanding was $ 180 million from Lloyd's of London as of December 31, 2023 and 2022. These programs also include reinsurance recoverables of $ 113 million and $ 183 million from Aleka Insurance Inc. as of December 31, 2023 and 2022, respectively.

 Repayment of debt On March 29, 2023, the Company repaid, at maturity, $ 250 million of Floating Rate Senior Notes that bear interest at a floating rate equal to three-month London Interbank Offered Rate

 ("LIBOR") plus 0.63 % per year. On June 15, 2023, the Company repaid, at maturity, $ 500 million of 3.15 % Senior Notes.
 Issuance of debt On March 31, 2023, the Company issued $ 750 million of 5.250 % Senior Notes due 2033. Interest on the Senior Notes is payable semi-annually in arrears on March 30 and September 30 of each year, beginning on September 30, 2023. The Senior Notes are redeemable at any time at the applicable redemption price prior to the maturity date. The net proceeds of this issuance were used to repay the $ 500 million senior debt maturity and for general corporate purposes.
 LIBOR-linked debt The administrator of LIBOR ceased the publication of the U.S. dollar ("USD") LIBOR settings on June 30, 2023. LIBOR was used as a

 benchmark or reference rate for Subordinated Debentures that the Company has issued.
 Subordinated Debentures The Subordinated Debentures allow for the use of an alternative methodology to determine the interest rate if LIBOR is no longer available. The Federal Reserve Board adopted a final rule that implemented the Adjustable Interest Rate (LIBOR) Act on December 16, 2022. This guidance impacts the alternative rate methodology utilized by the Subordinated Debentures.
 Both Subordinated Debentures replaced the three-month LIBOR with the CME Term SOFR Reference Rate published for a three-month tenor plus a spread adjustment of 0.26161 % effective for interest paid under the terms of each of the Subordinated Debentures after June 30, 2023, as shown in the table below.

 The Subordinated Debentures may be redeemed (i) in whole at any time or in part from time to time on or after January 15, 2023 for the 5.100 % Subordinated Debentures and August 15, 2023 for the 5.750 % Subordinated Debentures at their principal amount plus accrued and unpaid interest to, but excluding, the date of redemption; provided that if the Subordinated Debentures are not redeemed in whole, at least $ 25 million aggregate principal amount must remain outstanding, or (ii) in whole, but not in part, prior to January 15, 2023 for the 5.100 % Subordinated Debentures and August 15, 2023 for the 5.750 % Subordinated Debentures, within 90 days after the occurrence of certain tax and rating agency events, at their principal amount or, if greater, a make-whole redemption price, plus accrued and unpaid interest to, but excluding, the date of redemption. The 5.750 % Subordinated Debentures have this make-whole redemption price provision only when a reduction of equity credit assigned by a rating agency has occurred.
 Interest on the 5.100 % Subordinated Debentures was payable quarterly at the stated fixed annual rate to January 14, 2023, or any earlier redemption date, and then at an annual rate equal to the three-month LIBOR plus 3.165 %. Interest on the 5.750 % Subordinated Debentures was payable semi-annually at the stated fixed annual rate to August 14, 2023, or any earlier redemption date, and then quarterly at an annual rate equal to the three-month LIBOR plus 2.938 %.

 Junior Subordinated Debentures As of December 31, 2023, the Company had outstanding $ 500 million of Series A 6.500 % Fixed-to-Floating Rate Junior Subordinated Debentures ("Junior Subordinated Debentures"). The scheduled maturity date for the Debentures is May 15, 2057 with a final maturity date of May 15, 2067. The Junior Subordinated Debentures may be redeemed (i) in whole or in part, at any time on or after May 15, 2037 at the principal amount plus accrued and unpaid interest to the date of redemption, or (ii) in certain circumstances, in whole or in part, prior to May 15, 2037 at the principal amount plus accrued and unpaid interest to the date of redemption or, if greater, a make-whole price.
 Interest on the Junior Subordinated Debentures is payable semi-annually at the stated fixed annual rate to May 15, 2037, and then payable quarterly at an annual rate equal to the three-month LIBOR plus 2.120 %. The LIBOR Act guidance impacted the alternative rate methodology utilized by the Debentures. The Junior Subordinated Debentures replaced the three-month LIBOR with the CME Term SOFR Reference Rate published for a three-month tenor plus a spread adjustment of 0.26161 %. The Company may elect at one or more times to defer payment of interest on the Junior Subordinated Debentures for one or more consecutive interest periods that do not exceed 10 years. Interest compounds during such deferral periods at the rate in effect for each period. The interest deferral feature obligates the Company in certain circumstances to issue common stock or certain other types of securities if it cannot otherwise raise sufficient funds to make the required interest payments. The Company has reserved 75 million shares of its authorized and unissued common stock to satisfy this obligation.
 The terms of the Subordinated Debentures and Junior Subordinated Debentures prohibit the Company from declaring or paying any dividends or distributions on common or preferred stock or redeeming, purchasing, acquiring, or making liquidation payments on common stock or preferred stock if the Company has elected to defer interest payments on the Subordinated Debentures or Junior Subordinated Debentures, respectively, subject to certain limited exceptions.
 In connection with the issuance of the Junior Subordinated Debentures, the Company entered into a replacement capital covenant ("RCC"). This covenant was not intended for the benefit of the holders of the Junior Subordinated Debentures and could not be enforced by them. Rather, it was for the benefit of holders of one or more other designated series of the Company's indebtedness ("covered debt"), currently the $ 800 million Floating Rate Subordinated Debentures due in 2053. Pursuant to the RCC, the Company has agreed that it will not repay, redeem, or purchase the Junior Subordinated Debentures on or before May 15, 2067 (or such earlier date on which the RCC terminates by its terms) unless, subject to certain limitations, the Company has received net cash proceeds in specified amounts from the sale of common stock or certain other qualifying securities.

 166 www.allstate.com

 The promises and covenants contained in the RCC will not apply if (i) S&P upgrades the Company's issuer credit rating to A or above, (ii) the Company redeems the Junior Subordinated Debentures due to a tax event, (iii) after notice of redemption has been given by the Company and a market disruption event occurs preventing the Company from raising proceeds in accordance with the RCC, or (iv) the Company repurchases or redeems up to 10 % of the outstanding principal of the Junior Subordinated Debentures in any one-year period, provided that no more than 25 % will be so repurchased, redeemed or purchased in any ten-year period.
 The RCC terminates in 2067. The RCC will terminate prior to its scheduled termination date if (i) the Junior Subordinated Debentures are no longer outstanding and the Company has fulfilled its obligations under the RCC or it is no longer applicable, (ii) the holders of a majority of the then-outstanding principal amount of the then-effective series of covered debt consent to agree to the termination of the RCC, (iii) the Company does not have any series of outstanding debt that is eligible to be treated as covered debt under the RCC, (iv) the Junior Subordinated Debentures are accelerated as a result of an event of default, (v) certain rating agency or change in control events occur, (vi) S&P, or any successor thereto, no longer assigns a solicited rating on senior debt issued or guaranteed by the Company, or (vii) the termination of the RCC would have no effect on the equity credit provided by S&P with respect to the Junior Subordinated Debentures. An event of default, as defined by the supplemental indenture, includes default in the payment of interest or principal and bankruptcy proceedings.
 Other capital resources To manage short-term liquidity, the Company maintains a commercial paper program and a credit facility as a potential source of funds. In November, 2020, the Company entered into a new unsecured revolving credit facility agreement with a borrowing limit of $ 750 million. In November 2022, the maturity date was extended to November 2027 and the USD benchmark rate was amended from LIBOR to SOFR. This facility contains an increase provision that would allow up to an additional $ 500 million of borrowing. This facility has a financial covenant requiring the Company not to exceed a 37.5 % debt to capitalization ratio as defined in the agreement. Although the right to borrow under the facility is not subject to a minimum rating requirement, the costs of maintaining the facility and borrowing under it are based on the ratings of the Company's senior unsecured, unguaranteed long-term debt. The total amount outstanding at any point in time under

 the combination of the commercial paper program and the credit facility cannot exceed the amount that can be borrowed under the credit facility. No amounts were outstanding under the credit facility as of December 31, 2023 or 2022. The Company had no commercial paper outstanding as of December 31, 2023 or 2022.
 The Company paid $ 355 million, $ 323 million and $ 321 million of interest on debt in 2023, 2022 and 2021, respectively.
 The Company had $ 209 million and $ 371 million of investment-related debt that is reported in other liabilities and accrued expenses as of December 31, 2023 and 2022, respectively.
 During 2021, the Company filed a universal shelf registration statement with the Securities and Exchange Commission ("SEC") that expires in 2024. The registration statement covers an unspecified amount of securities and can be used to issue debt securities, common stock, preferred stock, depositary shares, warrants, stock purchase contracts, stock purchase units and securities of trust subsidiaries.
 Common stock The Company had 900 million shares of issued common stock of which 262 million shares were outstanding and 638 million shares were held in treasury as of December 31, 2023. In 2023, the Company acquired 3 million shares at an average cost of $ 118.18 and reissued 2 million net shares under equity incentive plans.
 Preferred stock All outstanding preferred stock represents noncumulative perpetual preferred stock with a $ 1.00 par value per share and a liquidation preference of $ 25,000 per share.
 Redemption of preferred stock On April 17, 2023, the Company redeemed all 23,000 shares of Fixed Rate Noncumulative Preferred Stock, Series G, par value $ 1.00 per share and liquidation preference amount of $ 25,000 per share, and the corresponding depositary shares for a total redemption payment of $ 575 million. The Company recognized $ 18 million of original issuance costs in preferred stock dividends on the Consolidated Statements of Operations and Consolidated Statements of Shareholders' Equity.
 Issuance of preferred stock On May 18, 2023, the Company issued 24,000 shares of Fixed Rate Noncumulative Preferred Stock, Series J, par value $ 1.00 per share and liquidation preference amount of $ 25,000 per share, and the corresponding depositary shares for gross proceeds of $ 600 million.

 The preferred stock ranks senior to the Company's common stock with respect to the payment of dividends and liquidation rights. The Company will pay dividends on the preferred stock on a noncumulative basis only when, as and if declared by the Company's board of directors (or a duly authorized committee of the board) and to the extent that the Company has legally available funds to pay dividends. If dividends are declared on the preferred stock, they will be payable quarterly in arrears at an annual fixed rate. Dividends on the preferred stock are not cumulative. Accordingly, in the event dividends are not declared on the preferred stock for payment on any dividend payment date, then those dividends will cease to be payable. If the Company has not declared a dividend before the dividend payment date for any dividend period, the Company has no obligation to pay dividends for that dividend period, whether or not dividends are declared for any future dividend period. No dividends may be paid or declared on the Company's common stock and no shares of the Company's common stock may be repurchased unless the full dividends for the latest completed dividend period on the preferred stock have been declared and paid or provided for.
 The preferred stock does not have voting rights except with respect to certain changes in the terms of the preferred stock, in the case of certain dividend nonpayments, certain other fundamental corporate events, mergers or consolidations and as otherwise provided by law. If and when dividends have not been declared and paid in full for at least six quarterly dividend periods or their equivalent (whether or not consecutive), the authorized number of directors then constituting the Company's board of directors will be increased by two. The holders of the preferred stock, together with the holders of all other affected classes and series of voting parity stock, voting as a single class, will be entitled to elect the two additional members of the board of directors of the Company, subject to certain conditions. The board of directors

 shall at no time have more than two preferred stock directors.
 The preferred stock is perpetual and has no maturity date. The preferred stock is redeemable at the Company's option in whole or in part, on or after October 15, 2024 for Series H, January 15, 2025 for Series I and July 15, 2028 for Series J at a redemption price of $ 25,000 per share, plus declared and unpaid dividends. Prior to October 15, 2024 for Series H, January 15, 2025 for Series I and July 15, 2028 for Series J, the preferred stock is redeemable at the Company's option, in whole but not in part, within 90 days after the occurrence of certain regulatory capital events at a redemption price equal to $ 25,000 per share or within 90 days after the occurrence of a certain rating agency event at a redemption price equal to $ 25,500 per share, plus declared and unpaid dividends for Series H, I and J, respectively.

 Note 14
 Company Restructuring

 The Company undertakes various programs to reduce expenses. These programs generally involve a reduction in staffing levels, and in certain cases, office closures. Restructuring and related charges primarily include the following costs related to these programs:
 • Employee - severance and relocation benefits
 • Exit - contract termination penalties and real estate costs primarily related to accelerated amortization of right-of-use assets and related leasehold improvements at facilities to be vacated
 The expenses related to these activities are included in the Consolidated Statements of Operations as restructuring and related charges and totaled $ 169 million, $ 51 million and $ 170 million in 2023, 2022 and 2021, respectively.

 Restructuring expenses in 2023 primarily relate to implementing actions to streamline the organization and outsource operations, and real estate costs related to facilities being vacated. The Company continues to identify ways to improve operating efficiency and reduce cost which may result in additional restructuring charges in the future.

 Note 15
 Commitments, Guarantees and Contingent Liabilities

 Shared markets and state facility assessments
 The Company is required to participate in assigned risk plans, reinsurance facilities and joint underwriting associations in various states that provide insurance coverage to individuals or entities that otherwise are unable to purchase such coverage from private insurers.
 The Company routinely reviews its exposure to assessments from these plans, facilities and government programs. Underwriting results related to these arrangements, which tend to be adverse, have been immaterial to the Company's results of operations in the last three years. Because of the Company's participation, it may be exposed to losses that surpass the capitalization of these facilities or assessments from these facilities.
 Florida Citizens Castle Key is subject to assessments from Citizens Property Insurance Corporation in the state of Florida ("FL Citizens"), which was initially created by the state of Florida to provide insurance to property owners unable to obtain coverage in the private insurance market. FL Citizens, at the discretion and direction of its Board of Governors, can levy a regular assessment on assessable insurers and assessable insureds for a deficit in any calendar year up to a maximum of the

 greater of: 2 % of the projected deficit or 2 % of the aggregate statewide direct written premium for the prior calendar year. The base of assessable insurers includes all property and casualty premiums in the state, except workers' compensation, medical malpractice, accident and health insurance and policies written under the NFIP. An insurer may recoup a regular assessment through a surcharge to policyholders. In order to recoup this assessment, an insurer must file for a policy surcharge with the Florida Office of Insurance Regulation at least fifteen days prior to imposing the surcharge on policies. If a deficit remains after the regular assessment, FL Citizens can also levy emergency assessments in the current and subsequent years. Companies are required to collect the emergency assessments directly from residential property policyholders and remit to FL Citizens as collected. Currently, the emergency assessment is zero for all policies issued or renewed on or after July 1, 2015.
 Louisiana Citizens Louisiana Citizens Property Insurance Corporation ("LA Citizens") can levy a regular assessment on participating companies for a deficit in any calendar year up to a maximum of the greater of 10 % of the calendar year deficit or 10 % of Louisiana direct property premiums industry-wide for the prior calendar year. If the plan year deficit exceeds the

 The Allstate Corporation 169

 amount that can be recovered through regular assessments, LA Citizens may fund the remaining deficit by issuing revenue assessment bonds in the capital markets. LA Citizens then declares emergency assessments each year to provide debt service on the bonds until they are retired. Companies writing assessable lines must surcharge their policyholders emergency assessments in the percentage established annually by LA Citizens and must remit amounts collected to the bond trustee on a quarterly basis. Emergency assessments to pay off bonds issued in 2007 for the hurricanes of 2005 will continue until 2025.
 Facilities such as FL Citizens and LA Citizens are generally designed so that the ultimate cost is borne by policyholders; however, the exposure to assessments from these facilities and the availability of recoupments or premium rate increases may not offset each other in the Company's financial statements. Moreover, even if they do offset each other, they may not offset each other in financial statements for the same fiscal period due to the ultimate timing of the assessments and recoupments or premium rate increases, as well as the possibility of policies not being renewed in subsequent years.
 California Earthquake Authority Exposure to certain potential losses from earthquakes in California is limited by the Company's participation in the California Earthquake Authority ("CEA"), which provides insurance for California earthquake losses. The CEA is a privately-financed, publicly-managed state agency created to provide insurance coverage for earthquake damage. Insurers selling homeowners insurance in California are required to offer earthquake insurance to their customers either through their company or by participation in the CEA. The Company's homeowners policies continue to include coverages for losses caused by explosions, theft, glass breakage and fires following an earthquake, which are not underwritten by the CEA.
 As of October 31, 2023, the CEA's capital balance was approximately $ 6.00 billion. Should losses arising from an earthquake cause a deficit in the CEA, an additional $ 2.10 billion would be obtained from the proceeds of revenue bonds the CEA may issue, an existing $ 9.30 billion reinsurance layer, $ 1.00 billion from policy surcharge, and finally, if needed, assessments on participating insurance companies. Participating insurers are required to pay an assessment, currently estimated not to exceed $ 1.70 billion, if the capital of the CEA falls below $ 350 million. Within the limits previously described, the assessment could be intended to restore the CEA's capital to a level of $ 350 million. There is no provision that allows insurers to recover assessments through a premium surcharge or other mechanism. The CEA's projected aggregate claim paying capacity is $ 20.10 billion as of October 31, 2023 and if an event were to result in claims greater than its capacity, affected policyholders may be paid a prorated portion of their covered losses, paid on an installment basis, or no payments may be made if the claim paying capacity of the CEA is insufficient.

 All future assessments on participating CEA insurers are based on their CEA insurance market share as of December 31 of the preceding year. As of December 31, 2023, the Company's market share was 8.5 %. The Company's market share will increase 0.3 % with the addition of National General as a participating CEA insurer in 2023. At the current level, the Company's maximum possible CEA assessment was $ 141 million during 2023. These amounts are re-evaluated by the board of directors of the CEA on an annual basis. Accordingly, assessments from the CEA for a particular quarter or annual period may be material to the results of operations and cash flows, but not the financial position of the Company. Management believes the Company's exposure to earthquake losses in California has been significantly reduced as a result of its participation in the CEA.
 Texas Windstorm Insurance Association The Company participates as a member of the Texas Windstorm Insurance Association ("TWIA"), which provides wind and hail property coverage to coastal risks unable to procure coverage in the voluntary market. Wind and hail coverage is written on a TWIA-issued policy. TWIA follows a funding structure first utilizing currently available funds set aside from current and prior years. Under the current law, to the extent losses exceed premiums received from policyholders, TWIA utilizes a combination of reinsurance, TWIA issued securities, as well as member and policyholder assessments to fund loss payments.
 Any assessments from TWIA for a particular quarter or annual period may be material to the results of operations and cash flows, but not to the financial position of the Company.
 North Carolina Joint Underwriters Association The North Carolina Joint Underwriters Association ("NCJUA") was created to provide property insurance for properties, other than the state's beach and coastal areas, that insurers are not otherwise willing to insure. All insurers licensed to write property insurance in North Carolina are members of the NCJUA. Premiums, losses and expenses of the NCJUA are shared by the member companies in proportion to their respective North Carolina property insurance writings. Member companies participate in plan deficits or surpluses based on their participation ratios, which are determined annually. The Company had a $ 7 million receivable from the NCJUA at December 31, 2023 representing its participation in the NCJUA's surplus of $ 10 million for all open years.
 North Carolina Insurance Underwriting Association The North Carolina Insurance Underwriting Association ("NCIUA") provides property insurance, including windstorm and hail coverage, for properties located in the state's beach and coastal areas that insurers are not otherwise willing to insure. All insurers licensed to write residential and commercial property insurance in North Carolina are members of the NCIUA. Members are assessed in proportion to their North Carolina residential and commercial property insurance writings, which is determined annually and varies by coverage, for plan deficits. As of December 31, 2023,

 170 www.allstate.com

 the NCIUA had a surplus of $ 1.03 billion. No member company is entitled to the distribution of any portion of the NCIUA's surplus. The Company does not recognize any interest related to this surplus. Legislation in 2009 capped insurers' assessments for losses incurred in any calendar year at $ 1.00 billion. Subsequent to an industry assessment of $ 1.00 billion, if the plan continues to require funding, it may authorize insurers to assess a 10 % catastrophe recovery charge on each property insurance policy statewide to be remitted to the plan.
 Other programs The Company is also subject to assessments by the NCRF and the FHCF, which are described in Note 11.
 Guaranty funds
 Under state insurance guaranty fund laws, insurers doing business in a state can be assessed, up to prescribed limits, for certain obligations of insolvent insurance companies to policyholders and claimants. Amounts assessed to each company are typically related to its proportion of business written in each state. The Company's policy is to accrue assessments when the entity for which the insolvency relates has met its state of domicile's statutory definition of insolvency, the amount of the loss is reasonably estimable and the related premium upon which the assessment is based is written. In most states, the definition is met with a declaration of financial insolvency by a court of competent jurisdiction. In certain states there must also be a final order of liquidation. Since most states allow a credit against premium or other state related taxes for assessments, an asset is recorded based on paid and accrued assessments for the amount the Company expects to recover on the respective state's tax return and is realized over the period allowed by each state. As of December 31, 2023 and 2022, the liability balance included in other liabilities and accrued expenses was $ 23 million and $ 29 million, respectively. The related premium tax offsets included in other assets were $ 5 million and $ 6 million as of December 31, 2023 and 2022, respectively.
 Guarantees
 In the normal course of business, the Company provides standard indemnifications to contractual counterparties in connection with numerous transactions, including acquisitions and divestitures. The types of indemnifications typically provided include indemnifications for breaches of representations and warranties, taxes and certain other liabilities, such as third-party lawsuits. The indemnification clauses are often standard contractual terms and are entered into in the normal course of business based on an assessment that the risk of loss would be remote. The terms of the indemnifications vary in duration and nature. In many cases, the maximum obligation is not explicitly stated and the contingencies triggering the obligation to indemnify have not occurred and are not expected to occur. Consequently, the maximum amount of the obligation under such indemnifications is not determinable.

 Historically, the Company has not made any material payments pursuant to these obligations.
 Related to the sale of ALNY on October 1, 2021, AIC agreed to indemnify Wilton Reassurance Company in connection with certain representations, warranties and covenants of AIC, and certain liabilities specifically excluded from the transaction, subject to specific contractual limitations regarding AIC's maximum obligation. Management does not believe these indemnifications will have a material effect on results of operations, cash flows or financial position of the Company.
 Related to the sale of ALIC and Allstate Assurance Company on November 1, 2021, AIC and Allstate Financial Insurance Holdings Corporation (collectively, the "Sellers") agreed to indemnify Everlake US Holdings Company in connection with certain representations, warranties and covenants of the Sellers, and certain liabilities specifically excluded from the transaction, subject to specific contractual limitations regarding the Sellers' maximum obligation. Management does not believe these indemnifications will have a material effect on results of operations, cash flows or financial position of the Company.
 The aggregate liability balance related to all guarantees was not material as of December 31, 2023.
 Regulation and compliance
 The Company is subject to extensive laws, regulations, administrative directives, and regulatory actions. From time to time, regulatory authorities or legislative bodies seek to influence and restrict premium rates, require premium refunds to policyholders, require reinstatement of terminated policies, prescribe rules or guidelines on how affiliates compete in the marketplace, restrict the ability of insurers to cancel or non-renew policies, require insurers to continue to write new policies or limit their ability to write new policies, limit insurers' ability to change coverage terms or to impose underwriting standards, impose additional regulations regarding agency and broker compensation, regulate the nature of and amount of investments, impose fines and penalties for unintended errors or mistakes, impose additional regulations regarding cybersecurity and privacy, and otherwise expand overall regulation of insurance products and the insurance industry. In addition, the Company is subject to laws and regulations administered and enforced by federal agencies, international agencies, and other organizations, including but not limited to the Securities and Exchange Commission ("SEC"), the Financial Industry Regulatory Authority, the U.S. Equal Employment Opportunity Commission, and the U.S. Department of Justice. The Company has established procedures and policies to facilitate compliance with laws and regulations, to foster prudent business operations, and to support financial reporting. The Company routinely reviews its practices to validate compliance with laws and regulations and with internal procedures and policies. As a result of these reviews, from time to time the Company may decide to modify some of its procedures and policies. Such

 The Allstate Corporation 171

 modifications, and the reviews that led to them, may be accompanied by payments being made and costs being incurred. The ultimate changes and eventual effects of these actions on the Company's business, if any, are uncertain.
 Legal and regulatory proceedings and inquiries
 The Company and certain subsidiaries are involved in a number of lawsuits, regulatory inquiries, and other legal proceedings arising out of various aspects of its business.
 Background These matters raise difficult and complicated factual and legal issues and are subject to many uncertainties and complexities, including the underlying facts of each matter; novel legal issues; variations between jurisdictions in which matters are being litigated, heard, or investigated; changes in assigned judges; differences or developments in applicable laws and judicial interpretations; judges reconsidering prior rulings; the length of time before many of these matters might be resolved by settlement, through litigation, or otherwise; adjustments with respect to anticipated trial schedules and other proceedings; developments in similar actions against other companies; the fact that some of the lawsuits are putative class actions in which a class has not been certified and in which the purported class may not be clearly defined; the fact that some of the lawsuits involve multi-state class actions in which the applicable law(s) for the claims at issue is in dispute and therefore unclear; and the challenging legal environment faced by corporations and insurance companies.
 The outcome of these matters may be affected by decisions, verdicts, and settlements, and the timing of such decisions, verdicts, and settlements, in other individual and class action lawsuits that involve the Company, other insurers, or other entities and by other legal, governmental, and regulatory actions that involve the Company, other insurers, or other entities. The outcome may also be affected by future state or federal legislation, the timing or substance of which cannot be predicted.
 In the lawsuits, plaintiffs seek a variety of remedies which may include equitable relief in the form of injunctive and other remedies and monetary relief in the form of contractual and extra-contractual damages. In some cases, the monetary damages sought may include punitive or treble damages. Often specific information about the relief sought, such as the amount of damages, is not available because plaintiffs have not requested specific relief in their pleadings. When specific monetary demands are made, they are often set just below a state court jurisdictional limit in order to seek the maximum amount available in state court, regardless of the specifics of the case, while still avoiding the risk of removal to federal court. In Allstate's experience, monetary demands in pleadings bear little relation to the ultimate loss, if any, to the Company.
 In connection with regulatory examinations and proceedings, government authorities may seek various

 forms of relief, including penalties, restitution, and changes in business practices. The Company may not be advised of the nature and extent of relief sought until the final stages of the examination or proceeding.
 Accrual and disclosure policy The Company reviews its lawsuits, regulatory inquiries, and other legal proceedings on an ongoing basis and follows appropriate accounting guidance when making accrual and disclosure decisions. The Company establishes accruals for such matters at management's best estimate when the Company assesses that it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. The Company does not establish accruals for such matters when the Company does not believe both that it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. The Company's assessment of whether a loss is reasonably possible or probable is based on its assessment of the ultimate outcome of the matter following all appeals. The Company does not include potential recoveries in its estimates of reasonably possible or probable losses. Legal fees are expensed as incurred.
 The Company continues to monitor its lawsuits, regulatory inquiries, and other legal proceedings for further developments that would make the loss contingency both probable and estimable, and accordingly accruable, or that could affect the amount of accruals that have been previously established. There may continue to be exposure to loss in excess of any amount accrued. Disclosure of the nature and amount of an accrual is made when there have been sufficient legal and factual developments such that the Company's ability to resolve the matter would not be impaired by the disclosure of the amount of accrual.
 When the Company assesses it is reasonably possible or probable that a loss has been incurred, it discloses the matter. When it is possible to estimate the reasonably possible loss or range of loss above the amount accrued, if any, for the matters disclosed, that estimate is aggregated and disclosed. Disclosure is not required when an estimate of the reasonably possible loss or range of loss cannot be made.
 For certain of the matters described below in the "Claims related proceedings" and "Other proceedings" subsections, the Company is able to estimate the reasonably possible loss or range of loss above the amount accrued, if any. In determining whether it is possible to estimate the reasonably possible loss or range of loss, the Company reviews and evaluates the disclosed matters, in conjunction with counsel, in light of potentially relevant factual and legal developments.
 These developments may include information learned through the discovery process, rulings on dispositive motions, settlement discussions, information obtained from other sources, experience from managing these and other matters, and other rulings by courts, arbitrators or others. When the Company possesses sufficient appropriate information to develop an estimate of the reasonably possible loss or range of loss above the amount accrued, if any, that estimate is aggregated and disclosed below. There

 172 www.allstate.com

 may be other disclosed matters for which a loss is probable or reasonably possible, but such an estimate is not possible. Disclosure of the estimate of the reasonably possible loss or range of loss above the amount accrued, if any, for any individual matter would only be considered when there have been sufficient legal and factual developments such that the Company's ability to resolve the matter would not be impaired by the disclosure of the individual estimate.
 The Company currently estimates that the aggregate range of reasonably possible loss in excess of the amount accrued, if any, for the disclosed matters where such an estimate is possible is zero to $ 56 million, pre-tax. This disclosure is not an indication of expected loss, if any. Under accounting guidance, an event is "reasonably possible" if "the chance of the future event or events occurring is more than remote but less than likely" and an event is "remote" if "the chance of the future event or events occurring is slight." This estimate is based upon currently available information and is subject to significant judgment and a variety of assumptions and known and unknown uncertainties. The matters underlying the estimate will change from time to time, and actual results may vary significantly from the current estimate. The estimate does not include matters or losses for which an estimate is not possible. Therefore, this estimate represents an estimate of possible loss only for certain matters meeting these criteria. It does not represent the Company's maximum possible loss exposure. Information is provided below regarding the nature of all of the disclosed matters and, where specified, the amount, if any, of plaintiff claims associated with these loss contingencies.
 Due to the complexity and scope of the matters disclosed in the "Claims related proceedings" and "Other proceedings" subsections below and the many uncertainties that exist, the ultimate outcome of these matters cannot be predicted and in the Company's judgment, a loss, in excess of amounts accrued, if any, is not probable. In the event of an unfavorable outcome in one or more of these matters, the ultimate liability may be in excess of amounts currently accrued, if any, and may be material to the Company's operating results or cash flows for a particular quarterly or annual period. However, based on information currently known to it, management believes that the ultimate outcome of all matters described below, as they are resolved over time, is not likely to have a material effect on the financial position of the Company.
 Claims related proceedings The Company is managing various disputes in Florida that raise challenges to the Company's practices, processes, and procedures relating to claims for personal injury protection benefits under Florida auto policies. Medical providers continue to pursue litigation under various theories that challenge the amounts that the Company pays under the personal injury protection coverage, seeking additional benefit payments, as well as applicable interest, penalties and fees. There is a pending lawsuit, Revival Chiropractic v. Allstate Insurance Company, et al. (M.D. Fla. filed January 2019; appeal pending, Eleventh Circuit Court of Appeals),

 where the federal district court denied class certification and plaintiff's request to file a renewed motion for class certification. In Revival, on June 2, 2022, the Eleventh Circuit certified to the Florida Supreme Court Allstate's appeal of the federal district court's interpretation of the state personal injury protection statute. The Eleventh Circuit is holding determination on plaintiff's class certification appeal pending the outcome of the Florida Supreme Court certification. The oral argument before the Florida Supreme Court was on March 8, 2023. The Company is also defending litigation involving individual plaintiffs.
 The Company is defending putative class actions in various courts that raise challenges to the Company's depreciation practices in homeowner property claims. In these lawsuits, plaintiffs generally allege that, when calculating actual cash value, the costs of "non-materials" such as labor, general contractor's overhead and profit, and sales tax should not be subject to depreciation. The Company is currently defending the following lawsuits on this issue: Sims, et al. v. Allstate Fire and Casualty Insurance Company, et al. (W.D. Tex. filed June 2022); Thompson, et al. v. Allstate Insurance Company (Circuit Court of Cole Co., Mo. filed June 2022); Hill v. Allstate Vehicle and Property Insurance Company (Circuit Court of Cole Co., Mo. filed October 2022); Tabuga v. Allstate Vehicle and Property Insurance Company (D. Md. filed April 2023); and Hernandez v. Allstate Vehicle and Property Insurance Company (D. Ariz. filed April 2023) (the Shumway plaintiff was substituted with Hernandez). No classes have been certified in any of these matters.
 The Company is defending putative class actions pending in multiple states alleging that the Company underpays total loss vehicle physical damage claims on auto policies. The alleged systematic underpayments result from the following theories: (a) the third-party valuation tool used by the Company as part of a comprehensive adjustment process is allegedly flawed, biased, or contrary to applicable law; and/or (b) the Company allegedly does not pay sales tax, title fees, registration fees, and/or other specified fees that are allegedly mandatory under policy language or state legal authority.
 The Company is currently defending the following lawsuits: Kronenberg v. Allstate Insurance Company and Allstate Fire and Casualty Insurance Company (E.D.N.Y. filed December 2018); Durgin v. Allstate Property and Casualty Insurance Company (W.D. La. filed June 2019); Golla v. Allstate Insurance Company (N.D. Ohio filed June 2023); Bibbs v. Allstate Insurance Company and Allstate Fire and Casualty Insurance Company (N.D. Ohio filed August 2023); Hail v. Allstate Property and Casualty Insurance Company (State Court of Habersham Co., Ga. filed December 2023); and Katz v. Esurance Property and Casualty Insurance Company and National General Insurance Company (E.D.N.Y. filed February 2024). No classes have been certified in any of these matters.
 Settlements in principle have been reached in the following cases: Bass v. Imperial Fire and Casualty Insurance Company (W.D. La. filed February 2022); and

 Cummings v. Allstate Property and Casualty Insurance Company (M.D. La. filed April 2022).
 The Company is defending putative class actions in Arizona federal court that are alleging underpayment of uninsured/underinsured motorist claims. The lawsuits are Dorazio v. Allstate Fire and Casualty Insurance Company (D. Ariz. filed December 2022) and Loughran v. MIC General Insurance Corporation (D. Ariz. filed December 2022). The plaintiffs allege that uninsured/underinsured motorist coverages must be stacked where the defendants allegedly did not include specified policy language and did not provide specified notice to policyholders. No classes have been certified in these matters. In July 2023, the Arizona Supreme Court issued a ruling in Franklin v. CSAA General Insurance, a matter involving another insurer. The Franklin decision held, under the factual circumstances of that case, that stacking of uninsured/underinsured motorist coverages was required because the insurer did not include specified policy language and did not issue specified notice.
 The Company is currently defending its insureds against plaintiffs' bodily injury lawsuit stemming from a 2018 automobile accident, Equihua v. Chausse and Nash (Superior Court of Los Angeles Co., Cal. filed Jan. 2019). On August 18, 2021, a jury returned a verdict against the insureds. The Company then moved to intervene in the lawsuit on September 9, 2021 and together with the insureds, sought to vacate the judgment and to obtain a new trial. On November 2, 2021, the trial court denied the post-trial motions to vacate the judgment and for a new trial and the Company's motion to intervene. The Company and the insureds subsequently filed an appeal with the California Court of Appeal, Second District, which affirmed judgment in favor of plaintiffs on November 6, 2023. On December 18, 2023, the insureds filed a petition for review with the California Supreme Court. On February 14, 2024, the California Supreme Court entered an order denying the petition for review.
 Other proceedings The Company has pending an investigatory hearing before the California Insurance Commissioner concerning the private passenger automobile insurance rating practices of Allstate Insurance Company and Allstate Indemnity Company in California. The investigatory hearing is captioned In the Matter of the Rating Practices of Allstate Insurance Company and Allstate Indemnity Company. Pursuant to the Notice of Hearing issued by the California Insurance Commissioner, the California Insurance Commissioner is investigating: (1) whether Allstate has potentially violated California insurance law by using illegal price optimization; (2) how Allstate implemented any such potentially illegal price optimization in its private passenger auto insurance rates and/or class plans; and (3) how such potentially illegal price optimization impacted Allstate's private passenger auto insurance policyholders. Fact discovery was completed in the investigatory hearing. Allstate and the California Department of Insurance have reached an agreement in principle to resolve the investigatory hearing. The May 22, 2023 hearing was continued. A new hearing date has not been set.

 In re The Allstate Corp. Securities Litigation is a certified class action filed on November 11, 2016, in the United States District Court for the Northern District of Illinois against the Company and two of its officers asserting claims under the federal securities laws. Plaintiffs allege that they purchased Allstate common stock during the class period and suffered damages as the result of the conduct alleged. Plaintiffs seek an unspecified amount of damages, costs, attorney's fees, and other relief as the court deems appropriate. Plaintiffs allege that the Company and certain senior officers made allegedly material misstatements or omissions concerning claim frequency statistics and the reasons for a claim frequency increase for Allstate brand auto insurance between October 2014 and August 3, 2015.
 Plaintiffs further allege that a senior officer engaged in stock option exercises during that time allegedly while in possession of material nonpublic information about Allstate brand auto insurance claim frequency. The Company, its chairman, president and chief executive officer, and its former president are the named defendants. After the court denied their motion to dismiss on February 27, 2018, defendants answered the complaint, denying plaintiffs' allegations that there was any misstatement or omission or other misconduct. On June 22, 2018, plaintiffs filed their motion for class certification. The court allowed the lead plaintiffs to amend their complaint to add the City of Providence Employee Retirement System as a proposed class representative and on September 12, 2018, the amended complaint was filed. A class was certified on March 26, 2019, vacated by the U.S. Court of Appeals for the Seventh Circuit on July 16, 2020 and remanded for further consideration by the district court. On December 21, 2020, the district court again granted plaintiffs' motion for class certification and certified a class consisting of all persons who purchased Allstate common stock between October 29, 2014 and August 3, 2015. Defendants' petition for permission to appeal this ruling was denied on January 28, 2021. Following the close of discovery, defendants moved for summary judgment on March 23, 2022. On July 26, 2022, the court entered its order granting summary judgment in part (as to plaintiffs' claims relating to certain statements made in October 2014) and denying it as to the remainder of plaintiffs' claims. On January 10, 2023, the parties filed a joint pre-trial order. A pre-trial conference did not occur. Subsequently, on June 28, 2023, the parties reached an agreement in principle to settle the action, without any admission of liability or wrongdoing. On September 26, 2023, an order was entered by the district court granting preliminary approval of the class settlement. On December 19, 2023, the district court granted final approval of the class settlement. No appeal was filed.
 The Company is continuing to defend two putative class actions in California federal court, Holland Hewitt v. Allstate Life Insurance Company (E.D. Cal. filed May 2020) and Farley v. Lincoln Benefit Life Company (E.D. Cal. filed Dec. 2020), following the sale of ALIC. On April 19, 2023, the district court certified a class in Farley. LBL is appealing the district court's order in the Ninth Circuit Court of Appeals. There has been no ruling on

 174 www.allstate.com

 plaintiff's motion for class certification in Hewitt. In these cases, plaintiffs generally allege that the defendants failed to comply with certain California statutes which address contractual grace periods and lapse notice requirements for certain life insurance policies. Plaintiffs claim that these statutes apply to life insurance policies that existed before the statutes' effective date. The plaintiffs seek damages and injunctive relief. Similar litigation is pending against

 other insurance carriers. In August 2021, the California Supreme Court in McHugh v. Protective Life, a matter involving another insurer, determined that the statutory notice requirements apply to life insurance policies issued before the statutes' effective date. The Company asserts various defenses to plaintiffs' claims and to class certification.

 Note 16
 Income Taxes

 The Company and its eligible domestic subsidiaries file a U.S. consolidated federal income tax return. The Company also files tax returns in various states and foreign jurisdictions. Tax liabilities and benefits realized by the consolidated group are allocated as generated by the respective entities.
 Deferred income taxes result from temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements that will result in taxable or deductible amounts in future years. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in years in which those temporary differences are expected to be recovered or settled. Deferred tax assets and liabilities are adjusted through income tax expense as changes in tax laws or rates are enacted.
 Inflation Reduction Act of 2022 The Inflation Reduction Act of 2022 ("Act"), which contains several tax-related provisions, was signed into law on August 16, 2022. The Act created a 15% corporate alternative minimum tax ("CAMT") on certain large corporations and an excise tax of 1% on stock repurchases by publicly traded U.S. corporations, both effective after December 31, 2022. The excise tax on common stock repurchases is classified as an additional cost of the stock acquired included in treasury stock in shareholders' equity.
 In addition, under the CAMT rules, the Company has determined that it is considered an "Applicable Corporation" which requires computation of federal income tax liability under two tax systems, the U.S. regular corporate tax and the CAMT. Although the CAMT may apply in any given year where the CAMT liability exceeds the regular tax liability, the CAMT would generate a non-expiring tax credit carryforward which would be accounted for as a deferred tax asset. The CAMT credit can be used to reduce regular tax in future years when the regular tax liability is greater than the CAMT liability.
 The impact of a change in tax law is required to be recognized in the period of enactment. As such in assessing the realizability of our deferred tax assets, including determination of valuation allowance, the Company has made an accounting policy election to evaluate the realizability of deferred tax assets excluding the impact of the CAMT.

 15% Global Minimum Tax The Organization for Economic Cooperation and Development ("OECD") secured agreement from nearly 140 countries to address how corporate profits are taxed for multinational enterprises ("MNEs"). OECD has released Pillar Two Model Rules, a 15% minimum effective tax rate (also known as the Global Anti-Base Erosion "GloBE" Rules), designed to ensure that large MNEs pay a minimum level of tax on the income arising in each jurisdiction where they operate and mandates sharing of certain company information with taxing authorities on a local and global basis.
 Certain jurisdictions have enacted, and others have proposed, legislation to implement certain provisions of Pillar Two for fiscal years beginning on or after December 31, 2023. The Company is continuing to monitor the implications resulting from the potential enactment of Pillar Two rules in the jurisdictions where it operates.
 Regulatory tax examinations On January 4, 2021 and October 1, 2021, the Company acquired National General and SafeAuto, respectively. For tax years prior to the acquisition, National General is under a separate audit by the Internal Revenue Service ("IRS"). The IRS has completed its exam of Allstate's tax years prior to 2017 and National General tax years prior to 2015. Currently, the Company is under exam for the 2017 and 2018 tax years and National General is under exam for the 2015 through 2019 tax years. The Company believes that adequate provision has been made in the consolidated financial statements for any potential adjustments that may result from IRS examinations or any other tax authorities related to all open tax years.
 Unrecognized tax benefits The Company recognizes tax positions in the consolidated financial statements only when it is more likely than not that the position will be sustained on examination by the relevant taxing authority based on the technical merits of the position. A position that meets this standard is measured at the largest amount of benefit that will more likely than not be realized on settlement. A liability is established for differences between positions taken in a tax return and amounts recognized in the consolidated financial statements.

 The Company believes that it is reasonably possible that a portion of the unrecognized tax benefits could decrease within the next twelve months as a result of the lapse of the applicable statute of limitations, which is not expected to be material to the financial statements.
 The Company recognizes interest expense related to uncertain tax benefits in income tax (benefit)

 expense and penalties in operating costs and expenses. For the years ended December 31, 2023, 2022, and 2021, interest expense related to unrecognized tax benefits of $ 7 million, $ 3 million, and zero was recorded, respectively. The total accrued interest expense and penalties as of December 31, 2023 and 2022 were $ 24 million and $ 17 million, respectively.

 As of December 31, 2023, the Company has U.S. federal, state and foreign net operating loss ("NOL") and general business credit carryforwards. In assessing the realizability of gross deferred tax assets, management considers whether it is more likely than not that some portion or all of the gross deferred tax assets will not be realized. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in

 making this assessment, as well as limitations on use in future periods. Accordingly, management believes that it is more likely than not that the benefit from certain NOL carryforwards will not be fully realized. The Company has a valuation allowance of $ 69 million on the deferred tax assets related to these NOL carryforwards.

 Statutory Financial Information and Dividend Limitations

 Allstate's domestic property and casualty and life, accident and health insurance subsidiaries prepare their statutory-basis financial statements in conformity with accounting practices prescribed or permitted by the insurance department of the applicable state of domicile. Prescribed statutory accounting practices include a variety of publications of the NAIC, as well as state laws, regulations and general administrative rules. Permitted statutory accounting practices encompass all accounting practices not so prescribed.

 All states require domiciled insurance companies to prepare statutory-basis financial statements in conformity with the NAIC Accounting Practices and Procedures Manual, subject to any deviations prescribed or permitted by the applicable insurance commissioner or director. Statutory accounting practices differ from GAAP primarily since they require charging policy acquisition costs to expense as incurred, establishing life insurance reserves based on different actuarial assumptions, and valuing certain investments and establishing deferred taxes on a different basis.

 Dividend Limitations
 There are no regulatory restrictions that limit the payment of dividends by the Corporation, except those generally applicable to corporations incorporated in Delaware. Dividends are payable only out of certain components of shareholders' equity as permitted by Delaware law. However, the ability of the Corporation to pay dividends is dependent on business conditions, income, cash requirements of the Company, receipt of dividends from AIC and other relevant factors.
 The payment of shareholder dividends by AIC without the prior approval of the Illinois Department of Insurance ("IL DOI") is limited to formula amounts based on net income and capital and surplus, determined in conformity with statutory accounting practices, as well as the timing and amount of dividends paid in the preceding twelve months. There were no dividends paid by AIC in 2023. The maximum amount of dividends AIC will be able to pay without prior IL DOI approval at a given point in time during 2024 is $ 1.20 billion, less dividends paid during the preceding twelve months measured at that point in time. The payment of a dividend in excess of this amount requires 30 days advance written notice to the IL DOI. The dividend is deemed approved, unless the IL DOI disapproves it within the 30 -day notice period. Additionally, any dividend must be paid out of unassigned surplus excluding unrealized appreciation from investments, which for AIC totaled $ 7.15 billion as of December 31, 2023, and cannot result in capital and surplus being less than the minimum amount required by law.
 Under state insurance laws, insurance companies are required to maintain paid up capital of not less

 than the minimum capital requirement applicable to the types of insurance they are authorized to write. Insurance companies are also subject to risk-based capital ("RBC") requirements adopted by state insurance regulators. A company's "authorized control level RBC" is calculated using various factors applied to certain financial balances and activity. Companies that do not maintain adjusted statutory capital and surplus at a level in excess of the company action level RBC, which is two times authorized control level RBC, are required to notify and file a RBC remediation plan to the domiciliary regulator and provide a copy of the remediation plan to state insurance regulators in which the insurer is authorized to do business. Company action level RBC is significantly in excess of the minimum capital requirements. Total adjusted statutory capital and surplus and authorized control level RBC of AIC were $ 11.99 billion and $ 3.07 billion, respectively, as of December 31, 2023. Most of the Corporation's insurance subsidiaries are subsidiaries of or reinsure all of their business to AIC. AIC's subsidiaries are included as a component of AIC's total statutory capital and surplus.
 The amount of restricted net assets, as represented by the Corporation's investment in its insurance subsidiaries, was $ 21.18 billion as of December 31, 2023.
 Intercompany transactions
 Notification and approval of intercompany lending activities is also required by the IL DOI for transactions that exceed a level that is based on a formula using statutory admitted assets and statutory surplus.

 Note 18
 Benefit Plans

 Pension and other postretirement plans
 Defined benefit pension plans cover most U.S. employees. Benefits under the U.S. pension plans are based upon the employee's length of service, eligible annual compensation and, prior to January 1, 2014, either a cash balance or final average pay formula. A cash balance formula applies to all eligible employees hired after August 1, 2002. Eligible employees hired before August 1, 2002 chose between the cash balance formula and the final average pay formula. In July 2013, the Company amended its primary plans effective January 1, 2014 to introduce a new cash balance formula to replace the previous formulas (including the final average pay formula and the previous cash balance formula) under which eligible employees accrue benefits.

 The Company also provides a medical coverage subsidy for eligible employees hired before January 1, 2003, including their eligible dependents, when they retire and certain life insurance benefits for eligible retirees ("postretirement benefits"). Effective January 1, 2021, the Company eliminated the medical coverage subsidy for employees who were not eligible to retire as of December 31, 2020.
 Certain employees may become eligible for a medical subsidy if they retire in accordance with the terms of the applicable plans and are insured under the Company's group plans or other approved plans in accordance with the plan's participation requirements. The Company shares the cost of retiree medical benefits with non Medicare-eligible retirees based on years of service, with the Company's share being

 178 www.allstate.com

 subject to a 5 % limit on future annual medical cost inflation after retirement. For Medicare-eligible retirees, the Company provides a fixed Company contribution based on years of service and other factors, which is not subject to adjustments for inflation.
 In July 2013, the Company amended the plan to eliminate the life insurance benefits effective January 1, 2014 for current eligible employees and effective January 1, 2016 for eligible retirees who retired after 1989. Subject to a court order, the Company paid life insurance premiums for certain retiree plaintiffs until their lawsuit seeking to keep their life insurance benefits intact was resolved. In September 2020, the court entered summary judgment in favor of the Company and dismissed the action, releasing the Company from the order requiring the continued payment of premiums for certain retirees. In December 2021, the Court of Appeals affirmed summary judgment in favor of the Company. In October 2022, the U.S. Supreme Court denied the plaintiffs' petition for appeal. On December 13, 2022, the trial court denied the plaintiffs' motions to vacate the summary judgment decision and seek further discovery. On December 15, 2023, the 11th Circuit Court of Appeals affirmed the trial court's denial of plaintiffs' motion to vacate. This decision is subject to any appeals.

 The Company has reserved the right to modify or terminate its benefit plans at any time and for any reason.
 Obligations and funded status
 The Company calculates benefit obligations based upon generally accepted actuarial methodologies using the projected benefit obligation ("PBO") for pension plans and the accumulated postretirement benefit obligation ("APBO") for other postretirement plans. Pension costs and other postretirement obligations are determined using a December 31 measurement date. The benefit obligations represent the actuarial present value of all benefits attributed to employee service rendered as of the measurement date. The PBO is measured using the pension benefit formulas and assumptions. A plan's funded status is calculated as the difference between the benefit obligation and the fair value of plan assets. The Company's funding policy for the pension plans is to make contributions at a level in accordance with regulations under the Internal Revenue Code ("IRC") and generally accepted actuarial principles. The Company's other postretirement benefit plans are not funded.

 The prior service credit is recognized as a component of net cost for pension and other postretirement plans amortized over the average remaining service period of active employees expected to receive benefits.
 The accumulated benefit obligation ("ABO") for all defined benefit pension plans was $ 4.48 billion and $ 4.42 billion as of December 31, 2023 and 2022, respectively. The ABO is the actuarial present value of all benefits attributed by the pension benefit formula
 to employee service rendered at the measurement date. However, it differs from the PBO due to the

 exclusion of an assumption as to future compensation levels.
 The PBO, ABO and fair value of plan assets for the Company's pension plans with an ABO in excess of plan assets were $ 4.27 billion, $ 4.18 billion and $ 4.09 billion, respectively, as of December 31, 2023 and $ 84 million, $ 83 million and zero, respectively, as of December 31, 2022. Included in the accrued benefit cost of the pension benefits are certain unfunded non-qualified plans with accrued benefit costs of $ 78 million and $ 84 million for 2023 and 2022, respectively.

 The service cost component is the actuarial present value of the benefits attributed by the plans' benefit formula to services rendered by the employees during the period.
 Interest cost is the increase in the PBO in the period due to the passage of time at the discount rate.
 Interest cost fluctuates as the discount rate changes and is also impacted by the related change in the size of the PBO.
 The expected return on plan assets is determined as the product of the expected long-term rate of return on plan assets and the fair value of plan assets.

 Pension and other postretirement service cost, interest cost, expected return on plan assets, amortization of prior service credit and curtailment gains and losses are reported in property and casualty insurance claims and claims expense, operating costs and expenses, net investment income and (if applicable) restructuring and related charges on the Consolidated Statements of Operations.
 Remeasurement gains and losses relate to changes in discount rates, the differences between actual return on plan assets and the expected long-term rate of return on plan assets, and differences between actual plan experience and actuarial assumptions.

 The weighted average health care cost trend rate used in measuring the accumulated postretirement benefit cost is 6.8 % for 2024, gradually declining to 4.5 % in 2035 and remaining at that level thereafter.
 Pension plan assets In general, the Company's pension plan assets are managed in accordance with investment policies approved by pension investment committees. The purpose of the policies is to ensure the plans' long-term ability to meet benefit obligations by prudently investing plan assets and Company contributions, while taking into consideration regulatory and legal requirements and current market conditions. The investment policies are reviewed periodically and specify target plan asset allocation by asset category. In addition, the policies specify various asset allocation and other risk limits. The target asset allocation takes the plans' funding status into

 consideration, among other factors, including anticipated demographic changes or liquidity requirements that may affect the funding status such as the potential impact of lump sum settlements as well as existing or expected market conditions. In general, the allocation has a lower overall investment risk when a plan is in a stronger funded status position since there is less economic incentive to take risk to increase the expected returns on the plan assets. The pension plans' asset exposure within each asset category is tracked against widely accepted established benchmarks for each asset class with limits on variation from the benchmark established in the investment policy. Pension plan assets are regularly monitored for compliance with these limits and other risk limits specified in the investment policies.

 (1)The target asset allocation considers risk-based exposure while the actual percentage of plan assets utilizes a financial reporting view excluding exposure provided through derivatives.
 (2)Securities lending collateral reinvestment of $ 180 million and $ 297 million is excluded from the table above in 2023 and 2022, respectively.
 The target asset allocation for an asset category may be achieved either through direct investment holdings, through replication using derivative instruments (e.g., futures or swaps) or net of hedges using derivative instruments to reduce exposure to an asset category. The net notional amount of derivatives used for replication and non-hedging strategies is limited to 115 % of total plan assets. Market performance of the different asset categories may, from time to time, cause deviation from the target

 asset allocation. The asset allocation mix is reviewed on a periodic basis and rebalanced to bring the allocation within the target ranges.
 Outside the target asset allocation, the pension plans participate in a securities lending program to enhance returns. As of both December 31, 2023 and 2022, fixed income securities are lent out and cash collateral is invested in short-term investments.

 (3)The securities lending obligation represents the plan's obligation to return securities lending collateral received under a securities lending program. The terms of the program allow both the plan and the counterparty the right and ability to redeem/return the securities loaned on short notice. Due to its relatively short-term nature, the outstanding balance of the obligation approximates fair value.
 (4)Other net plan assets represent cash and cash equivalents, interest and dividends receivable and net receivables related to settlements of investment transactions, such as purchases and sales.
 The fair values of pension plan assets are estimated using the same methodologies and inputs as those used to determine the fair values for the respective asset category of the Company. These methodologies and inputs are disclosed in Note 6.

 The expected long-term rate of return on plan assets reflects the average rate of earnings expected on plan assets. The Company's assumption for the expected long-term rate of return on plan assets is evaluated annually giving consideration to appropriate data including, but not limited to, the plan asset allocation, forward-looking expected returns for the period over which benefits will be paid, historical returns on plan assets and other relevant market data. Given the long-term forward-looking nature of this assumption, the actual returns in any one year do not immediately result in a change to the expected long-term rate of return on plan assets. In consideration of the targeted plan asset allocation, the Company evaluated expected returns using sources including historical average asset class returns from independent nationally recognized providers of this type of data blended together using the asset allocation policy weights for the Company's pension plans; asset class return forecasts developed by employees with relevant expertise in such forecasts and who are independent from those charged with managing the pension plan assets; and expected portfolio returns from a proprietary simulation methodology of a widely recognized external

 investment consulting firm that performs asset allocation and actuarial services for corporate pension plan sponsors. The above sources support the Company's weighted average long-term rate of return on plan assets assumption of 7.35 % used for 2023 and an estimate of 7.34 % that will be used for 2024. As of the 2023 measurement date, the arithmetic average of the annual actual return on plan assets for the most recent 10 and 5 years was 8.3 % and 10.0 %, respectively.
 Cash flows There was no required cash contribution necessary to satisfy the minimum funding requirement under the IRC for the tax qualified pension plan for the year ended December 31, 2023.
 The Company currently plans to contribute $ 19 million to its unfunded non-qualified plans and zero to both its primary and other qualified funded pension plans in 2024.
 The Company contributed $ 26 million and $ 26 million to the postretirement benefit plans in 2023 and 2022, respectively. Contributions by participants were $ 16 million and $ 16 million in 2023 and 2022, respectively.

 The Company records compensation expense related to awards under these plans over the shorter of the period in which the requisite service is rendered or retirement eligibility is attained. Compensation expense for performance stock awards with no market condition is based on the probable number of awards expected to vest using the performance level most likely to be achieved at the end of the performance period. Compensation expense for performance stock awards with a market condition is based on the number of awards expected to vest as estimated at the grant date and does not change if the market condition is not met.

 Options are granted to employees with exercise prices equal to the closing share price of the Company's common stock on the applicable grant date. Options granted to employees vest ratably over a three-year period. Vesting is subject to continued service, except for employees who are retirement eligible and in certain other limited circumstances. Options may be exercised once vested and will expire no later than ten years after the date of grant.
 Restricted stock units for directors vest immediately and convert into shares of stock on the earlier of the day of the third anniversary of the grant date or the date the director's service terminates, unless a deferred period of restriction is elected. Restricted stock units granted to directors prior to June 1, 2016 convert upon leaving the board. Restricted stock units granted to employees prior to February 19, 2020 vest on the day prior to the third anniversary of the grant date. Restricted stock units granted to employees on or after February 19, 2020 vest ratably over a three-year period. Restricted stock units granted to employees subsequently convert into shares of stock on the day of the respective anniversary of the grant date. Vesting is subject to continued service, except for employees who are

 184 www.allstate.com

 retirement eligible and in certain other limited circumstances.
 Performance stock awards vest into shares of stock based on achieving established company-specific performance goals. Performance stock awards granted prior to February 19, 2020 vest into shares of stock on the day prior to the third anniversary of the grant date. Performance stock awards granted on or after February 19, 2020 vest into shares of stock on the third anniversary of the grant date.
 The numbers of shares earned upon vesting of the performance stock awards is based on the attainment of performance goals for each of the performance periods, subject to continued service, except for employees who are retirement eligible and in certain other limited circumstances.
 Since 2001, a total of 110.8 million shares of common stock were authorized to be used for awards under the plans, subject to adjustment in accordance with the plans' terms. As of December 31, 2023, 12.3 million shares were reserved and remained available

 for future issuance under these plans. The Company uses its treasury shares for these issuances.
 The fair value of each option grant is estimated on the date of grant using a binomial lattice model. The Company uses historical data to estimate option exercise and employee termination within the valuation model. In addition, separate groups of employees that have similar historical exercise behavior are considered separately for valuation purposes. The expected term of options granted is derived from the output of the binomial lattice model and represents the period of time that options granted are expected to be outstanding. The expected volatility of the price of the underlying shares is implied based on traded options and historical volatility of the Company's common stock. The expected dividends were based on the current dividend yield of the Company's stock as of the date of the grant. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant.

 The change in performance stock awards primarily comprises awards vested and granted in 2023.
 The fair value of performance stock awards that do not include a market condition is based on the market value of the Company's stock as of the date of the grant.
 Starting with the February 2020 award, the fair value of performance stock awards includes a component with market-based condition measured on the grant date using a Monte Carlo simulation model. Market-based condition measures the Company's total shareholder return ("TSR") relative to the TSR of peer companies, expressed in terms of the Company's TSR percentile rank among the peer companies, over a three-calendar-year performance period. The Monte Carlo simulation model uses a risk-neutral framework to model future stock price movements based upon the risk-free rate of return at the time of grant, volatilities of the Company and the peer companies,

 and expected term assumed to be equal to the remaining measurement period. The market value in part reflects the payment of future dividends expected.
 For the year ended December 31, 2023, the 2023 performance stock awards with market-based condition assumes a risk-free rate of 1.7 %, volatility of 24.8 %, average peer volatility of 29.9 % and an expected term of 2.9 years.
 The weighted average grant date fair value of performance stock awards granted was $ 136.62, $ 123.08 and $ 107.14 during 2023, 2022 and 2021, respectively. The total fair value of performance stock awards vested was $ 41 million, $ 87 million and $ 70 million during 2023, 2022 and 2021, respectively.
 The Company recognizes all tax effects related to share-based payments at settlement or expiration through the income statement.

 (1)For periods presented with a net loss from continuing operations applicable to common shareholders, weighted average shares for basic earnings per share is also used for calculating diluted earnings per share because all dilutive potential common shares are anti-dilutive and are therefore excluded from the calculation.
 Consolidated net income applicable to common shareholders was $ 1.46 billion in the fourth quarter of 2023 compared to net loss of $ 303 million in the fourth quarter of 2022, primarily due to improved underwriting results.
 Effective January 1, 2023, the Company adopted the FASB guidance revising the accounting for certain long-duration insurance contracts using the modified retrospective approach to the transition date of January 1, 2021.

 We have audited the accompanying Consolidated Statements of Financial Position of The Allstate Corporation and subsidiaries (the "Company") as of December 31, 2023 and 2022, the related Consolidated Statements of Operations, Comprehensive Income (Loss), Shareholders' Equity, and Cash Flows, for each of the three years in the period ended December 31, 2023, and the related notes and the schedules listed in the Index at Item 15 (collectively referred to as the "financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
 In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.
 Change in Accounting Principle
 As discussed in Note 2 to the financial statements, the Company has changed its method of accounting for the measurement and disclosure of long-duration insurance contracts using the modified retrospective approach to the transition date of January 1, 2021 due to the adoption of Accounting Standards Update 2018-12, Targeted Improvements to the Accounting for Long-Duration Contracts.
 Basis for Opinions
 The Company's management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Item 9A. Controls and Procedures. Our responsibility is to express an opinion on these financial statements and an opinion on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
 We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
 Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.
 Definition and Limitations of Internal Control over Financial Reporting
 A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.
 Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

 Critical Audit Matter
 The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
 Reserve for Property and Casualty Insurance Claims and Claims Expense - Refer to Notes 2 and 9 to the Financial Statements
 Critical Audit Matter Description
 The Company establishes reserves for property and casualty insurance claims and claims expense on reported and unreported claims of insured losses. Using established industry and actuarial best practices as well as the Company's historical claims experience, the reserve for property and casualty insurance claims and claims expense is estimated based on (i) claims reported, (ii) claims incurred but not reported, and (iii) projections of claim payments to be made in the future.
 Given the subjectivity of estimating claims incurred but not reported and projections of claim payments to be made in the future, particularly those with payout requirements over a longer period of time, the related audit effort in evaluating the reserve for property and casualty insurance claims and claims expense required a high degree of auditor judgment and an increased extent of effort, including involvement of our actuarial specialists.
 How the Critical Audit Matter Was Addressed in the Audit
 Our principal audit procedures related to the reserve for property and casualty insurance claims and claims expense included the following:
 • We tested the effectiveness of controls related to the reserve for property and casualty insurance claims and claims expense, including those over the Company's estimates and projections.
 • We evaluated the methods and assumptions used by the Company to estimate the reserve for property and casualty insurance claims and claims expense by:
 –Testing the underlying data that served as the basis for the actuarial analysis, including historical claims, to test that the inputs to the actuarial estimate were complete and accurate.
 –Performing a retrospective review, including comparing prior year estimates of expected incurred losses to actual experience during the current year to identify potential bias in the determination of the reserve for property and casualty insurance claims and claims expense.
 • With the assistance of our actuarial specialists, we developed independent estimates for the reserve for property and casualty insurance claims and claims expense, particularly those with payout requirements over a longer period of time, utilizing loss data and industry claim development factors, and compared our estimates to management's estimates and assessed the consistency of management's approach.

 1. General
 Pursuant to rules and regulations of the Securities and Exchange Commission, the unconsolidated condensed financial statements of the Parent Company do not reflect all of the information and notes normally included with financial statements prepared in accordance with GAAP.

 Participating subsidiaries fund the pension plans contributions under a master services cost sharing agreement.
