 ITEM 1. BUSINESS
 CNA Financial Corporation (CNAF) was incorporated in 1967 and is an insurance holding company. References to "CNA," "the Company," "we," "our," "us" or like terms refer to the business of CNAF and its subsidiaries. CNA's property and casualty and remaining life and group insurance operations are primarily conducted by Continental Casualty Company (CCC), The Continental Insurance Company, Western Surety Company, CNA Insurance Company Limited, Hardy Underwriting Bermuda Limited and its subsidiaries (Hardy), and CNA Insurance Company (Europe) S.A. Loews Corporation (Loews) owned approximately 92% of our outstanding common stock as of December 31, 2023.
 Our insurance products primarily include commercial property and casualty coverages, including surety. Our services include warranty, risk management information services and claims administration. Our products and services are primarily marketed through independent agents, brokers and managing general underwriters to a wide variety of customers, including small, medium and large businesses, insurance companies, associations, professionals and other groups. The property and casualty insurance industry is highly competitive, both as it relates to rate and service. We compete with a large number of stock and mutual insurance companies, as well as other entities, for both distributors and customers.
 Our commercial property and casualty underwriting operations presence in the United States of America (U.S.) consists of field underwriting locations and centralized processing operations which handle policy processing, billing and collection activities and also act as call centers to optimize service. Our claim operations in the U.S. consists of primary locations where we handle multiple claim types and key business functions, as well as regional claim offices which are aligned with our underwriting field structure. We also have property and casualty underwriting operations in Canada, the United Kingdom (U.K.) and Continental Europe, as well as access to business placed at Lloyd's of London through Syndicate 382.
 Our commercial property and casualty insurance operations are managed and reported in three business segments: Specialty, Commercial and International, which we refer to collectively as Property & Casualty Operations. Our operations outside of Property & Casualty Operations are managed and reported in two business segments: Life & Group and Corporate & Other. Discussion of each segment, including the products offered, customers served and distribution channels used, is set forth in the Management's Discussion and Analysis (MD&A) included under Item 7 and in Note P to the Consolidated Financial Statements included under Item 8.
 Current Regulation
 The insurance industry is subject to comprehensive and detailed regulation and supervision. Regulatory oversight by applicable agencies is exercised through review of submitted filings and information, examinations (both financial and market conduct), direct inquiries and interviews. Each domestic and foreign jurisdiction has established supervisory agencies with broad administrative powers relative to licensing insurers and agents, approving policy forms, establishing reserve requirements, prescribing the form and content of statutory financial reports and regulating capital adequacy and the type, quality and amount of investments permitted. Such regulatory powers also extend to premium rate regulations requiring rates not be excessive, inadequate or unfairly discriminatory. In addition to regulation of dividends by insurance subsidiaries, intercompany transfers of assets or payments may be subject to prior notice or approval by insurance regulators, depending on the size of such transfers and payments in relation to the financial position of the insurance subsidiaries making the transfer or payments.
 As our insurance operations are conducted in both domestic and foreign jurisdictions, we are subject to a number of regulatory agency requirements applicable to a portion, or all, of our operations. These include but are not limited to, the State of Illinois Department of Insurance (which is our global group-wide supervisor), the U.K. Prudential Regulatory Authority and Financial Conduct Authority, the Office of Superintendent of Financial Institutions in Canada, the Luxembourg insurance regulator Commissariat aux Assurances (the CAA) and the Bermuda Monetary Authority.

 Domestic insurers are also required by state insurance regulators to provide coverage to certain insureds who would not otherwise be considered eligible by the insurers. Each state dictates the types of insurance and the level of coverage that must be provided to such involuntary risks. Our share of these involuntary risks is mandatory and generally a function of our respective share of the voluntary market by line of insurance in each state.
 Further, domestic insurance companies are subject to state guaranty fund and other insurance-related assessments. Guaranty funds are governed by state insurance guaranty associations which levy assessments to meet the funding needs of insolvent insurer estates. Other insurance-related assessments are generally levied by state agencies to fund various organizations, including disaster relief funds, rating bureaus, insurance departments and workers' compensation second injury funds, and by industry organizations that assist in the statistical analysis and ratemaking process, and we have the ability to recoup certain of these assessments from policyholders.
 Although the U.S. federal government does not currently directly regulate the business of insurance, federal legislative and regulatory initiatives can affect the insurance industry. These initiatives and legislation include proposals relating to terrorism and natural catastrophe exposures, federal financial services reforms and certain tax reforms.
 Hardy, a specialized Lloyd's of London (Lloyd's) underwriter, is also supervised by the Council of Lloyd's, which is the franchisor for all Lloyd's operations. The Council of Lloyd's has wide discretionary powers to regulate Lloyd's underwriting, such as establishing the capital requirements for syndicate participation. In addition, the annual business plan of each syndicate is subject to the review and approval of the Lloyd's Franchise Board, which is responsible for business planning and monitoring for all syndicates.
 Capital adequacy and risk management regulations, referred to as Solvency II, apply to our European operations and are enacted by the European Commission, the executive body of the European Union (E.U). Additionally, the International Association of Insurance Supervisors (IAIS) continues to develop capital requirements as more fully discussed below.
 Regulation Outlook
 The IAIS has adopted a Common Framework (ComFrame) for the supervision of Internationally Active Insurance Groups (IAIGs), which is focused on the group-wide supervision of IAIGs, such as CNA. As part of ComFrame, the IAIS has developed a global capital standard that, if adopted in the U.S., would be applicable to U.S.-based IAIGs. Certain elements of ComFrame were incorporated into regulatory guidelines issued by the National Association of Insurance Commissioners (NAIC) for application by regulators beginning in 2023. These additions were adopted for the purpose of streamlining group-wide supervision, further leveraging existing risk and solvency measures and applying them on a group-wide basis.
 The NAIC developed an approach to group capital regulation and solvency-monitoring activities using the Group Capital Calculation (GCC). While historically the U.S. regulatory regime was primarily based on legal entity regulation, the GCC quantifies risk across the insurance group. The GCC was adopted by the NAIC along with model legislative language and attendant regulations, which have been adopted in a number of U.S. states where IAIGs are domiciled, including Illinois. Alongside the GCC, the NAIC has also developed the Aggregation Method (AM) approach to assessing group capital as an alternative to the Insurance Capital Standard (ICS) developed by the IAIS. The AM is influenced by the GCC and calculated in a similar manner. A decision by the IAIS on whether the AM provides comparable outcomes to the ICS is expected in 2024.
 In addition, the U.S. and foreign regulatory environment in which we operate is continuously evolving, with both existing and prospective regulations that implicate aspects of our corporate governance, risk management practices, public disclosures, environmental, social and governance (ESG) related issues, artificial intelligence and cybersecurity.
 Human Capital
 As of December 31, 2023, we had approximately 6,300 employees. We seek to create a culture of inclusion that engages our employees and offers them opportunities to learn, grow and achieve their career goals. We believe this will facilitate our ability to continue to attract and retain a highly talented workforce.

 Talent, Recruitment and Development
 We focus on attracting, developing and retaining top-tier talent to reflect the specialist nature of our business.
 We aim to continually build on the expertise of our workforce. At entry levels, we have implemented trainee and internship programs and we continue to leverage relationships with colleges to attract new and diverse talent. We seek to promote the development of employees, both to optimize current performance and to develop skills for future career growth. We have implemented programs designed for our employees to grow their technical expertise, collaborate with one another and achieve their career goals. We offer a wide range of learning and development opportunities, including mentorship and reverse mentorship programs, apprenticeship and sponsorship programs, tuition reimbursement, technical training and specialized leadership development programs.
 CNA leaders engage regularly with our employees on their performance and professional development. We gather employee feedback through pulse surveys and routine dialogue with our employee resource groups and leaders from across the enterprise. Our annual talent and succession planning process culminates in a review with leadership of key talent retention and promotion, as well as a review of our succession plans. Our performance management cycle seeks to ensure that employees have goals and development plans refreshed at least annually and performance review conversations are held between managers and their direct reports throughout the annual performance period.
 Employee Benefits
 We offer comprehensive compensation and benefits packages to eligible employees including a 401k plan, healthcare and insurance benefits, health savings and flexible spending accounts, paid time off and certain family assistance programs, including paid family leave, flexible work arrangements and surrogacy and adoption assistance plans.
 We provide certain benefits to eligible employees that are geared toward enhancing physical, mental, financial and social health. These include a holistic well-being incentive program with resources for both employees and their families, employee mental health assistance programs, and stress management and resilience programs. CNA also offers remote working options and a hybrid-working environment for eligible employees.
 Diversity, Equity and Inclusion
 Diversity, Equity and Inclusion (DEI) is a strategic imperative. Our DEI Vision is to cultivate an inclusive culture grounded in equity that celebrates individuals' differences, attracts diverse talent, and fosters an environment that enables employees to do their best work.
 To act on our DEI Vision, CNA has appointed senior leaders to an executive DEI Council, and our Chairman and CEO serves as the Executive Sponsor. The DEI Council works closely with internal DEI subject matter experts and with our eight employee resource groups to create and drive strategic DEI initiatives.
 Critical components of our DEI Vision include:
 • Skill building. CNA offers DEI learning programs to all employees. After expanding our focus on allyship and equity, we refreshed our new hire onboarding, manager training and leadership development programs, and launched interactive workshops designed to provide opportunities to learn and practice new skills.
 • Leadership training. CNA requires every people leader and officer to complete inclusive leadership training. We also provide additional networking and learning opportunities for leaders to support the critical role they play in creating an inclusive workplace culture.
 • Talent development. CNA has a talent sponsorship program that seeks to accelerate the development of high performing diverse employees, diversify our leadership ranks and broadly build inclusive leadership skills. In addition, we offer mentoring and reverse mentoring program opportunities to employees.
 • Representation. We seek to increase the representation of diverse talent throughout the organization. We monitor our representation of diverse talent and review our trends in relation to the labor market

 and industry to understand how we can increase it. We also report this information regularly to our Board of Directors.
 • Partnerships. CNA has established new partnerships, and expanded several existing partnerships, with organizations whose DEI values and objectives align with our own. Through these partnerships, we uncover new sources of talent, support minority owned businesses, contribute to the development of students from underserved communities and provide opportunities for our employees to volunteer in their local communities.
 • Policies and benefits. We regularly review our workplace policies and employee benefits and seek to adapt them to the changing needs of our employees.
 We also have a corporate social responsibility strategy with a focus on four core areas: DEI, protecting the environment, science, technology, engineering and mathematics (STEM) education, and disaster preparedness and recovery. Our employees are encouraged to participate in a wide array of volunteer activities and we support their charitable giving by matching employee contributions to qualified nonprofit organizations.

 We file annual, quarterly and current reports, proxy statements and other documents with the Securities and Exchange Commission (SEC) under the Securities Exchange Act of 1934 (Exchange Act). The SEC maintains an internet site that contains reports, proxy and information statements and other information regarding issuers, including CNA. The public can obtain any documents that we file with the SEC at www.sec.gov.
 We also make available free of charge on or through our internet website at www.cna.com our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and amendments to those reports as soon as reasonably practicable after we electronically file such material with, or furnish it to, the SEC.

 ITEM 1A. RISK FACTORS
 Our business faces many risks and uncertainties. These risks and uncertainties could lead to events or circumstances that have a material adverse effect on our results of operations, equity, business and insurer financial strength and corporate debt ratings. We have described below material risks that we face. There may be additional risks that we do not yet know of or that we do not currently perceive to be material that may also affect our business. You should carefully consider and evaluate all of the information included in this report and any subsequent reports we may file with the SEC or make available to the public before investing in any securities we issue.
 Insurance Risks
 If we determine that our recorded insurance reserves are insufficient to cover our estimated ultimate unpaid liability for claim and claim adjustment expenses, we may need to increase our insurance reserves which would result in a charge to our earnings.
 We maintain insurance reserves to cover our estimated ultimate unpaid liability for claim and claim adjustment expenses, including the estimated cost of the claims adjudication process, for reported and unreported claims. Insurance reserves are not an exact calculation of liability but instead are complex management estimates developed utilizing a variety of actuarial reserve estimation techniques as of a given reporting date. The reserve estimation process involves a high degree of judgment and variability and is subject to a number of factors which are highly uncertain. These factors can be affected by both changes in internal processes and external events. Key variables include frequency of claims, claim severity, mortality, morbidity, discount rates, economic, social and medical inflation, claim handling policies and procedures, case reserving approach, underwriting and pricing policies, changes in the legal and regulatory environment and the lag time between the occurrence of an insured event and the time of its ultimate settlement. Mortality is the relative incidence of death. Morbidity is the frequency and severity of injury, illness, sickness and diseases contracted.
 There is generally a higher degree of variability in estimating required reserves for long-tail coverages, such as long-term care, workers' compensation, general liability and professional liability, as they require a relatively longer period of time for claims to be reported and settled. The impact of changes in economic and social inflation, and medical costs are also more pronounced for long-tail coverages due to the longer settlement period. Certain risks and uncertainties associated with our insurance reserves are outlined in the Critical Accounting Estimates and the Reserves - Estimates and Uncertainties sections of MD&A in Item 7.
 We are subject to the uncertain effects of emerging and potential claims and coverage issues that arise as industry practices and legal, judicial, social, economic and other environmental conditions change. Further, the impact of social inflation continues to be significant and the trajectory of its future impact remains uncertain. In addition, passage of reviver statutes that extend, or eliminate, the statute of limitations for the reporting of claims, including statutes passed in certain states with respect to sexual molestation and sexual abuse, increase the uncertainty of the frequency of claims. These issues, have had, and may continue to have, a negative effect on our business, results of operations and financial condition by either extending coverage beyond the original underwriting intent or by increasing the number or size of claims, resulting in further increases in our reserves. The effects of unforeseen emerging or potential claim and coverage issues are extremely difficult to predict and may be material.
 In light of the many uncertainties associated with establishing the estimates and making the judgments necessary to establish reserve levels, we continually review and change our reserve estimates in a regular and ongoing process as experience develops from the actual reporting and settlement of claims and as the legal, regulatory and economic environment evolves. When our recorded reserves are insufficient for any reason, the required increase in reserves is recorded as a charge against our earnings in the period in which reserves are determined to be insufficient. These charges have been and in the future could be substantial.

 Our actual experience could vary from the key assumptions used to determine future policy benefit reserves for long-term care policies.
 Our future policy benefit reserves for long-term care policies are based on our best estimate actuarial assumptions, which are assessed quarterly and updated at least annually. Key actuarial assumptions include morbidity, persistency (inclusive of mortality), anticipated future premium rate increases and expenses. The adequacy of the reserves is contingent upon actual experience and our future expectations related to these key assumptions. If actual or expected future experience differs from these assumptions, the reserves may not be adequate, requiring us to increase reserves. The required increase in reserves is recorded as a charge against our earnings in the period in which reserves are determined to be insufficient. These charges have been and in the future could be substantial. The reserves are discounted using upper-medium grade fixed income instrument yields as of each reporting date. Discount rates are subject to interest rate and market volatility. See the Life & Group Policyholder Reserves portion of Reserves - Estimates and Uncertainties section of MD&A in Item 7 for more information.
 Morbidity and persistency experience, inclusive of mortality, can be volatile and may be negatively affected by many factors including, but not limited to, policyholder behavior, judicial decisions regarding policy terms, socioeconomic factors, cost of care inflation, changes in health trends and advances in medical care.
 A prolonged period during which investment returns remain at low levels could result in shortfalls in investment income on assets supporting our obligations under long-term care policies. This risk is more significant for our long-term care products because the long potential duration of the policy obligations exceeds the duration of the supporting investment assets. In addition, we may not receive regulatory approval for the level of premium rate increases we request. Any adverse deviation between the level of future premium rate increases approved and the level included in our reserving assumptions may require an increase to our reserves.
 We are vulnerable to material losses from natural and man-made disasters.
 Catastrophe losses are an inevitable part of our business. Various events can cause catastrophe losses. These events can be natural or man-made, and may include hurricanes, tornadoes, windstorms, earthquakes, hail, severe winter weather, fires, floods, riots, strikes, civil unrest, cyber-attacks, pandemics and acts of terrorism. The frequency and severity of these catastrophe events are inherently unpredictable. Exposure to cyber risk is increasing systematically due to greater digital dependence, which increases the potential for, and the potential losses due to, a catastrophic cyber event. Catastrophic cyber-attack scenarios are not bound by time or geographic limitations and cyber-related catastrophic perils don't have well-established definitions or fundamental physical properties. In addition, longer-term natural catastrophe trends may be changing and new types of catastrophe losses may be developing due to climate change, its associated extreme weather events linked to rising temperatures and its effects on global weather patterns, greenhouse gases, sea, land and air temperatures, sea levels, rain, hail and snow. Climate studies by government agencies, academic institutions, catastrophe modeling organizations and other groups indicate that climate change may be altering the frequency and/or severity of catastrophic weather events, such as hurricanes, tornadoes, windstorms, floods and other natural disasters.
 The extent of our losses from catastrophes is a function of the total amount of our insured exposures in the affected areas, the frequency and severity of the events themselves, the level of our reinsurance coverage, reinsurance reinstatement premiums and state residual market assessments, if any. It can take a long time for the ultimate cost of any catastrophe losses to us to be finally determined, as a multitude of factors contribute to such costs, including evaluation of general liability and pollution exposures, infrastructure disruption, business interruption and reinsurance collectibility. Further, significant catastrophic events or a series of catastrophic events have the potential to impose financial stress on the reinsurance industry, which could impact our ability to collect amounts owed to us by reinsurers, thereby resulting in higher net incurred losses.
 Reinsurance coverage for "unconventional" terrorism events (such as nuclear, biological, chemical or radiological attacks) is provided only in limited circumstances. Our principal reinsurance protection against these large-scale terrorist attacks is the coverage currently provided through the Terrorism Risk Insurance Program Reauthorization Act of 2019 (TRIPRA) through December 31, 2027. However, such coverage is subject to a mandatory deductible and other limitations. It is also possible that future legislation could change

 or eliminate the program, which could adversely affect our business by increasing our exposure to terrorism losses, or by lowering our business volume through efforts to avoid that exposure. For a further discussion of TRIPRA, see Part II, Item 7, MD&A - Catastrophes and Related Reinsurance.
 As a result of the items discussed above, catastrophe losses are particularly difficult to estimate, could cause us to exhaust our available reinsurance limits, could lead to large losses and could adversely affect the cost and availability of reinsurance. Accordingly, catastrophic events could have a material adverse effect on our business, results of operations, financial condition and liquidity.
 The COVID-19 pandemic, including new or emerging variants, other potential pandemics and related measures to mitigate the spread of the foregoing may continue to have adverse impacts on our business, results of operations and financial condition and could be material.
 We have experienced, and may continue to experience, increased claim submissions and litigation related to denial of claims based on policy coverage or the facts of the claim, in certain lines of business that are implicated by the COVID-19 pandemic and mitigating actions taken by our customers and governmental authorities in response to its spread. These lines include primarily healthcare professional liability, workers' compensation, commercial property related business interruption coverage, management liability (directors and officers, employment practices and professional liability lines) and trade credit. We recorded significant losses during 2020, a significant portion of which remain classified as incurred but not reported (IBNR) reserves, in these areas and may experience continued losses, which could be material.
 Increased frequency or severity in any or all of the foregoing lines, or others where the exposure has yet to emerge, relating to long-term effects of COVID-19, new or emerging variants, or other potential pandemics, and related measures to mitigate the spread of the foregoing, may have a material impact on our business, results of operations and financial condition.
 We have incurred and may continue to incur substantial expenses related to litigation activity in connection with COVID-related legal claims. These actions primarily relate to denial of claims submitted as a result of the pandemic and the mitigating actions taken, including lockdowns and closing of certain businesses. The significance of such litigation or any other litigation relating to new or emerging variants of COVID-19 or other potential pandemics and related measures to mitigate the spread of the foregoing, both in substance and volume, and the resultant Company-initiated activities, including external counsel engagement, and the costs related thereto, may have a material impact on our business, results of operations and financial condition.
 We have exposures related to asbestos and environmental pollution (A&EP) claims, which could result in material losses.
 Our property and casualty insurance subsidiaries have exposures related to A&EP claims. Our experience has been that establishing claim and claim adjustment expense reserves for casualty coverages relating to A&EP claims is subject to uncertainties that are greater than those presented by more traditional property and casualty claims. Additionally, traditional actuarial methods and techniques employed to estimate the ultimate cost of claims for more traditional property and casualty exposures are less precise in estimating claim and claim adjustment expense reserves for A&EP. As a result, estimating the ultimate cost of both reported and unreported A&EP claims is subject to a higher degree of variability. On August 31, 2010, we completed a retroactive reinsurance transaction under which substantially all of our legacy A&EP liabilities were ceded to National Indemnity Company (NICO), a subsidiary of Berkshire Hathaway Inc., subject to an aggregate limit of $4 billion (Loss Portfolio Transfer). The cumulative amount ceded under the Loss Portfolio Transfer as of December 31, 2023 was $3.6 billion. If the other parties to the Loss Portfolio Transfer do not fully perform their obligations, net losses incurred on A&EP claims covered by the Loss Portfolio Transfer exceed the aggregate limit of $4 billion, or we determine we have exposures to A&EP claims not covered by the Loss Portfolio Transfer, we may need to increase our recorded net reserves which would result in a charge against our earnings. These charges could be substantial. Additionally, if the A&EP claims exceed the limit of the Loss Portfolio Transfer, we will need to assess whether to purchase additional limit or to reassume claim handling responsibility for A&EP claims from an affiliate of NICO. Any additional reinsurance premium or future claim handling costs would also reduce our earnings.
 We are exposed to, and may face adverse developments related to, mass tort claims that could arise from,

 among other things, our insureds' sale or use of potentially harmful products or substances, changes to the social and legal environment, such as those related to abuse reviver statutes, issues related to altered interpretation of coverage and other new and emerging claim theories.
 We face potential exposure to various types of existing, new and emerging mass tort claims, including those related to exposure to potentially harmful products or substances, such as glyphosate, lead paint, per- and polyfluoroalkyl substances (PFAS) and opioids; claims arising from changes that expand the right to sue, remove limitations on recovery, extend the statutes of limitations or otherwise repeal or weaken tort reforms, such as those related to abuse reviver statutes, including New York reviver statutes; and claims related to new and emerging theories of liability, such as those related to global warming and climate change. Evolving judicial interpretations and new legislation regarding the application of various tort theories and defenses, including application of various theories of joint and several liability, as well as the application of insurance coverage to these claims, give rise to new and potentially more severe claim activity. For example, we have recorded, and may continue to record, increases in our mass tort reserves, driven substantially by abuse reviver statutes that have resulted in increased claims. Similar and continuing mass tort claim activity, including activity based on changing judicial interpretations and recent and proposed legislation, could have a material adverse effect on our business, results of operations and financial condition.
 Strategic Risks
 We face intense competition in our industry; we may be adversely affected by the cyclical nature of the property and casualty business and the evolving landscape of our distribution network.
 All aspects of the insurance industry are highly competitive and we must continuously allocate resources to refine and improve our insurance products and services to remain competitive. We compete with a large number of stock and mutual insurance companies and other entities, some of which may be larger or have greater financial or other resources than we do, for both distributors and customers. This includes agents, brokers and managing general underwriters who may increasingly compete with us to the extent that markets continue to provide them with direct access to providers of capital seeking exposure to insurance risk. Insurers compete on the basis of many factors, including products, price, services, ratings and financial strength. The competitor landscape has evolved substantially in recent years, with significant consolidation and new market entrants, such as insurtech firms, resulting in increased pressures on our ability to remain competitive, particularly in obtaining pricing that is both attractive to our customer base and risk-appropriate to us.
 In addition, the property and casualty market is cyclical and has experienced periods characterized by relatively high levels of price competition, resulting in less restrictive underwriting standards and relatively low premium rates, followed by periods of relatively lower levels of competition, more selective underwriting standards and relatively high premium rates. We may lose business to competitors offering competitive insurance products at lower prices. As a result, our premium levels and expense ratio could be materially adversely impacted.
 We market our insurance products worldwide primarily through independent insurance agents, insurance brokers, and managing general underwriters who also promote and distribute the products of our competitors. Any change in our relationships with our distribution network agents, brokers or managing general underwriters, including as a result of consolidation or their increased promotion and distribution of our competitors' products, could adversely affect our ability to sell our products. As a result, our business volume and results of operations could be materially adversely impacted.
 Our underwriting strategies currently rely on the effectiveness of reinsurance arrangements and we accordingly face risks relating to reinsurance, including obtaining reinsurance at a cost or on terms and conditions we deem acceptable, reinsurance counterparty risk and ineffective reinsurance coverage.
 A primary reason we purchase reinsurance is to manage our exposure to risk, thereby facilitating our underwriting strategies in certain key areas. Under our ceded reinsurance arrangements, a reinsurer assumes a specified portion of our exposure in exchange for a specified portion of policy premiums. The availability and cost of the reinsurance protection we purchase, which affects the volatility and profitability of our business, as well as the level and types of risk we retain, is determined by many factors, including general economic conditions and conditions in the reinsurance market, such as the occurrence of significant reinsured events or

 unexpected adverse trends, including those associated with climate change. If we are unable to obtain sufficient reinsurance at a cost or on terms and conditions we deem acceptable, our risk exposure will not be mitigated to the degree desired or we may forego such increased risk, thereby adversely impacting our underwriting strategies. In addition, use of reinsurance exposes us to credit risk of the reinsurers, as the reinsurance arrangements do not relieve us of the liability to the customer. If a reinsurer is unable to meet its financial obligations under a reinsurance arrangement, we will remain obligated under the original policies issued to our customers. Furthermore, while we use various risk management methods, including the use of reinsurance, to effectively manage risk, there is the possibility that one or more natural catastrophes and/or terrorism or other events could result in claims substantially exceeding expectations, thereby making the reinsurance strategy significantly less effective. Such reinsurance-related risks could have a material adverse effect on our business, results of operations and financial condition and adversely affect our underwriting strategies in certain lines of business.
 We may be adversely affected by technological changes or disruptions in the insurance marketplace.
 Technological changes in the way insurance transactions are completed in the marketplace, and our ability to react effectively to such change, may present significant competitive risks. For example, more insurers are utilizing "big data" analytics to make underwriting and other decisions that impact product design and pricing. If such utilization is more effective than how we use our data and information, we will be at a competitive disadvantage. There can be no assurance that we will continue to compete effectively with our industry peers due to technological changes; accordingly, this may have a material adverse effect on our business, results of operations and financial condition.
 In addition, agents and brokers, technology companies, or other third parties may create alternate distribution channels for commercial business that may adversely impact product differentiation and pricing. For example, they may create a digitally enabled distribution channel that may adversely impact our competitive position. Our efforts or the efforts of agents and brokers with respect to new products or alternate distribution channels, as well as changes in the way agents and brokers utilize greater levels of data and technology, could adversely impact our business relationship with independent agents and brokers who currently market our products, resulting in a lower volume and/or profitability of business generated from these sources.
 We face considerable competition within our industry for qualified, specialized talent and any significant inability to attract and retain talent may adversely affect the execution of our business strategies.
 The successful execution of our business strategies depends on our ability to attract and retain qualified talent. Due to the intense competition in our industry and from businesses outside the industry for qualified employees, especially those in key positions and those possessing highly specialized knowledge and industry experience in areas such as underwriting, data and analytics and technology, we may encounter obstacles to our ability to attract and retain such employees, which could materially adversely affect our business, results of operations and financial condition.
 We are controlled by a single stockholder which could result in potential conflicts of interest.
 Loews beneficially owned approximately 92% of our outstanding shares of common stock as of December 31, 2023, and is in a position to control actions that require the consent of stockholders, including the election of directors, amendment of our Restated Certificate of Incorporation and any merger or sale of substantially all of our assets. In addition, four officers of Loews, along with the Co-Chairman of the Board of Loews, serve on our Board of Directors. We have also entered into services agreements and a registration rights agreement with Loews, and we may in the future enter into other agreements with Loews. It is possible that potential conflicts of interest could arise in the future for our directors who are also officers and/or directors of Loews with respect to a number of areas relating to the past and ongoing relationships of Loews and us, including tax and insurance matters, financial commitments and sales of common stock pursuant to registration rights or otherwise.

 Financial Risks
 We may incur significant realized and unrealized investment losses and volatility in net investment income arising from changes in the financial markets.
 Our investment portfolio is exposed to various risks, such as interest rate, credit spread, issuer default, equity prices and foreign currency, which are unpredictable. Financial markets are highly sensitive to changes in economic conditions, monetary policies, tax policies, interest rates, domestic and international geopolitical issues and many other factors. Changes in financial markets, including fluctuations in interest rates, credit, equity prices and foreign currency prices, and many other factors beyond our control can adversely affect the value of our investments, the realization of investment income and the rate at which we discount certain liabilities. Our investment portfolio is also subject to increased valuation uncertainties when investment markets are illiquid. The valuation of investments is more subjective when markets are illiquid, thereby increasing the risk that the estimated fair value (i.e., the carrying amount) of the portion of our investment portfolio that is carried at fair value in our financial statements is not reflective of the prices at which actual transactions could occur.
 We have significant holdings in fixed maturity investments that are sensitive to changes in interest rates. A decline in interest rates may reduce the returns earned on new fixed maturity investments, thereby reducing our net investment income, while an increase in interest rates may reduce the value of our existing fixed maturity investments, which could increase our net unrealized losses or reduce our net unrealized gains included in Accumulated other comprehensive income (AOCI). The value of our fixed maturity investments is also subject to risk that certain investments may default or become impaired due to deterioration in the financial condition of issuers of the investments we hold or in the underlying collateral of the security.
 In addition, we invest a portion of our assets in limited partnerships and common stock which are subject to greater market volatility than our fixed maturity investments. Limited partnership investments generally provide a lower level of liquidity than fixed maturity or equity investments, which may also limit our ability to withdraw funds from these investments. The timing and amount of income or losses on such investments is inherently variable and can contribute to volatility in reported earnings.
 Further, we hold a portfolio of commercial mortgage loans. We are subject to risk related to the recoverability of loan balances, which is influenced by declines in the estimated cash flows from underlying property leases, fair value of collateral, refinancing risk and the creditworthiness of tenants of credit tenant loan properties, where lease payments directly service the loan. Any changes in actual or expected collections would result in a charge to earnings.
 As a result of these factors, we may not earn an adequate return on our investments, may be required to write down the value of our investments and may incur losses on the disposition of our investments all of which could materially adversely affect our business, results of operations and financial condition.
 Operational Risks
 We use analytical models to assist our decision making in key areas such as pricing, reserving, catastrophe risks and capital modeling and may be adversely affected if actual results differ materially from the model outputs and related analyses.
 We use various modeling techniques and data analytics (e.g. scenarios, predictive, stochastic and forecasting) to analyze and estimate exposures, loss trends and other risks associated with our assets and liabilities. This includes both proprietary and third-party modeled outputs and related analyses to assist us in decision-making related to underwriting, pricing, capital allocation, reserving, investing, reinsurance and catastrophe risk, among other things. We incorporate numerous assumptions and forecasts about the future level and variability of policyholder behavior, loss frequency and severity, interest rates, equity markets, inflation, capital requirements, and currency exchange rates, among others. The modeled outputs and related analyses from both proprietary models and third parties are subject to various assumptions, uncertainties, model design errors and the inherent limitations of any statistical analysis. Further, climate change may make modeled outcomes less certain or produce new, non-modeled risks.

 In addition, the effectiveness of any model can be degraded by operational risks, including the improper use of the model, input errors, data errors and human error. As a result, actual results may differ materially from our modeled results. Our profitability and financial condition substantially depends on the extent to which our actual experience is consistent with assumptions we use in our models and ultimate model outputs. If, based upon these models or other factors, we misprice our products or fail to appropriately estimate the risks we are exposed to, our business, results of operations and financial condition may be materially adversely affected.
 Any significant interruption in the operation of our business functions, facilities and systems or our vendors' facilities and systems could result in a materially adverse effect on our operations.
 Our business is highly dependent upon our ability to perform, in an efficient and uninterrupted manner, through our employees or vendor relationships and using our and their facilities and systems, necessary business functions, such as internet support and 24-hour call centers, processing new and renewal business, providing customer service, processing and paying claims and other obligations and issuing financial statements.
 Our, or our vendors', facilities and systems could become unavailable, inoperable, or otherwise impaired from a variety of causes, including natural events, such as hurricanes, tornadoes, windstorms, earthquakes, severe winter weather and fires, or other events, such as explosions, terrorist attacks, computer security breaches or cyber-attacks, riots, hazardous material releases, medical epidemics or pandemics, utility outages, interruptions of data processing and storage systems or unavailability of communications facilities. An interruption in our system availability occurred in March 2021 as a result of a cybersecurity attack we sustained. Please refer to the immediately following risk factor for further information regarding this incident. Likewise, we could experience a significant failure, interruption or corruption of one or more of our or our vendors' information technology, telecommunications, or other systems for various reasons, including significant failures or interruptions that might occur as existing systems are replaced or upgraded. The shut-down or unavailability of one or more of our or our vendors' systems or facilities for these or any other reasons could significantly impair our ability to perform critical business functions in a timely basis.
 In addition, because our and our vendors' information technology and telecommunications systems interface with and depend on third-party systems, we could experience service denials if demand for such service exceeds capacity or a third-party system fails or experiences an interruption. If sustained or repeated, such events could result in a deterioration of our ability to perform necessary business functions.
 The foregoing risks could expose us to monetary and reputational damages. Potential additional exposures relating to significant interruptions to our operations may include substantially increased compliance costs, as well as increased costs relating to investments in computer system and security-related upgrades, and such costs may not be recoverable under our relevant insurance coverage. We have made, and continue to make, investments to improve our security and infrastructure. Some of these investments are a direct result of the March 2021 cybersecurity attack, described in the immediately following risk factor, which are not recoverable under existing insurance coverage.
 If our business continuity plans or system security do not sufficiently address these risks, they could have a material adverse effect on our business, results of operations and financial condition.
 Any significant breach in our data security infrastructure or our vendors' facilities and systems could disrupt business, cause financial losses and damage our reputation, and insurance coverage may not be available for claims related to a breach.
 A significant breach of our data security infrastructure may result from actions by our employees, vendors, third-party administrators, or unknown third parties or through cyber-attacks. The risk of a breach can exist whether software services are in our or third party administered data centers or are cloud-based software services. Breaches have occurred, and may occur again, in our systems and in the systems of our vendors and third-party administrators.
 Such a breach could affect our data framework or cause a failure to protect the personal information of our customers, claimants or employees, or sensitive and confidential information regarding our business or policyholders and may result in operational impairments and financial losses, significant harm to our reputation and the loss of business with existing or potential customers. The breach of confidential information also could

 give rise to legal liability and regulatory action under data protection and privacy laws, as well as evolving regulation in this regard. During the second quarter of 2023, we were notified of a breach in the file transfer software, MOVEit Transfer, used by a vendor of one of our third-party administrators. This incident resulted in required breach notifications to the Company's long-term care policyholders, with such notifications made by the subject vendor. While we do not believe such notifications and resultant actions will have a material adverse effect on our business, this or similar incidents, or any other such breach of our or our vendors' data security infrastructure could have a material adverse effect on our business, results of operations and financial condition.
 As previously disclosed, we sustained a sophisticated cybersecurity attack in March 2021 involving ransomware that caused a network disruption and impacted certain of our systems. Our investigation into the incident revealed that an unauthorized third party copied some personal information relating to certain current and former employees, contract workers and their dependents and certain other persons, including some policyholders. Although we currently have no indication that the impacted data has been misused, or that CNA or its policyholder data was specifically targeted by the unauthorized third party, we may be subject to subsequent investigations, claims or actions in addition to other costs, fines, penalties, or other obligations related to impacted data, whether or not such data is misused. In addition, the misuse, or perceived misuse, of sensitive or confidential information regarding our business or policyholders could cause harm to our reputation and result in the loss of business with existing or potential customers, which could adversely impact our business, results of operations and financial condition.
 Although we maintain cybersecurity insurance coverage insuring against costs resulting from cyber-attacks (including the March 2021 attack), we do not expect the amount available under our coverage policy to cover all losses from cyber-attacks. In addition, potential disputes with our insurers about the availability of insurance coverage could occur. Further, should we experience future cyber incidents, or should industry trends drive rate increases resulting from growth in volume and significance of cyber incidents broadly, we may incur higher costs for cybersecurity insurance coverage.
 The risks relating to future breaches in our, or our vendors', data security infrastructure, including in connection with cyber incidents, could have a material adverse effect on our business, results of operations or financial condition or may result in operational impairments and financial losses, as well as significant harm to our reputation.
 Inability to detect and prevent significant employee or third-party service provider misconduct, inadvertent errors and omissions, or exposure relating to functions performed on our behalf could result in a materially adverse effect on our business, results of operations and financial condition.
 We may incur losses which arise from employees or third-party service providers engaging in intentional, negligent or inadvertent misconduct, fraud, errors and omissions, failure to comply with internal guidelines, including with respect to underwriting authority, or failure to comply with regulatory requirements. Our or our third-party service providers' controls may not be able to detect all possible circumstances of such noncompliant activity and the internal structures in place to prevent this activity may not be effective in all cases. Any losses relating to such non-compliant activity could adversely affect our business, results of operations and financial condition.
 Portions of our insurance business is underwritten and serviced by third parties. With respect to underwriting, our contractual arrangements with third parties will typically grant them limited rights to write new and renewal policies, subject to contractual restrictions and obligations, including requiring them to underwrite within the terms of our licenses. Should these third parties issue policies that exceed these contractual restrictions, we could be deemed liable for such policies and subject to regulatory fines and penalties for any breach of licensing requirements. It is possible that in such circumstance we might not be fully indemnified for such third parties' contractual breaches.
 Additionally, we rely on certain third-party claims administrators, including the administrator of our long-term care claims, to handle policyholder services and perform significant claim administration and claim adjudication functions. Any failure by such administrator to properly perform service functions may result in losses as a result of over-payment of claims, legal claims against us and adverse regulatory enforcement exposure.

 We have also licensed certain systems from third parties. We cannot be certain that we will have access to these systems or that our information technology or application systems will continue to operate as intended.
 These risks could adversely impact our reputation and client relationships and have a material adverse effect on our business, results of operations and financial condition.
 Loss of key vendor relationships and issues relating to the transitioning of vendor relationships could compromise our ability to conduct business.
 In the event that one or more of our vendors suffers a bankruptcy, is sold to another entity, sustains a significant business interruption or otherwise becomes unable to continue to provide products or services at the requisite level, we may be adversely affected. We may suffer operational impairments and financial losses associated with transferring business to a new vendor, assisting a vendor with rectifying operational difficulties, failure by vendors to properly perform service functions or assuming previously outsourced operations ourselves. Our inability to provide for appropriate servicing if a vendor becomes unable to fulfill its contractual obligations to us, either through transitioning to another service provider temporarily or permanently or assuming servicing internally, may have a materially adverse effect on our business, results of operations and financial condition.
 We are subject to capital adequacy requirements and, if we are unable to maintain or raise sufficient capital to meet these requirements, regulatory agencies may restrict or prohibit us from operating our business.
 Insurance companies such as ours are subject to capital adequacy standards set by regulators to help identify companies that merit further regulatory attention. In the U.S., these standards apply specified risk factors to various asset, premium and reserve components of our legal entity statutory basis of accounting financial statements. Current rules, including those promulgated by insurance regulators and specialized markets, such as Lloyd's, require companies to maintain statutory capital and surplus at a specified minimum level determined using the applicable jurisdiction's regulatory capital adequacy formula. If we do not meet these minimum requirements, we may be restricted or prohibited from operating our business in the applicable jurisdictions and specialized markets. If we are required to record a material charge against earnings in connection with a change in estimated insurance reserves, or the occurrence of a catastrophic event or otherwise, or if we incur significant losses related to our investment portfolio, which severely deteriorates our capital position, we may violate these minimum capital adequacy requirements unless we are able to raise sufficient additional capital. We may be limited in our ability to raise significant amounts of capital on favorable terms or at all.
 The IAIS has adopted a ComFrame for the supervision of IAIGs and has developed a global capital standard that, if adopted in the U.S., would be applicable to U.S.-based IAIGs. The NAIC also developed the GCC and AM approach to assessing group capital as an alternative to the ICS developed by the IAIS. The development and adoption of these capital standards could increase our prescribed capital requirement, the level at which regulatory scrutiny intensifies, as well as significantly increase our cost of regulatory compliance.
 Our insurance subsidiaries, upon whom we depend for dividends in order to fund our corporate obligations, are limited by insurance regulators in their ability to pay dividends.
 We are a holding company and are dependent upon dividends, loans and other sources of cash from our subsidiaries in order to meet our obligations. Ordinary dividend payments, or dividends that do not require prior approval by the insurance subsidiaries' domiciliary insurance regulator, are generally limited to amounts determined by formulas that vary by jurisdiction. If we are restricted from paying or receiving intercompany dividends, by regulatory rule or otherwise, we may not be able to fund our corporate obligations and debt service requirements or pay our stockholders dividends from available cash. As a result, we would need to pursue other sources of capital which may be more expensive or may not be available at all.
 Rating agencies may downgrade their ratings of us, thereby adversely affecting our ability to write insurance at competitive rates or at all and increasing our cost of capital.
 Ratings are an important factor in establishing the competitive position of insurance companies. Our insurance company subsidiaries, as well as our public debt, are rated by rating agencies, including, A.M. Best Company (A.M. Best), Moody's Investors Service, Inc. (Moody's), Standard & Poor's (S&P) and Fitch Ratings, Inc. (Fitch). Ratings reflect the rating agency's opinions of an insurance company's or insurance holding company's

 financial strength, capital adequacy, enterprise risk management practices, operating performance, strategic position and ability to meet its obligations to policyholders and debt holders, and may also reflect opinions on other areas such as information security and climate risk, as well as ESG matters more broadly.
 The rating agencies may take action to lower our ratings in the future as a result of any significant financial loss or changes in the methodology or criteria applied by the rating agencies. The severity of the impact on our business is dependent on the level of downgrade and, for certain products, which rating agency takes the rating action. Among the adverse effects in the event of such downgrades would be the inability to obtain a material volume of business from certain major insurance brokers, the inability to sell a material volume of our insurance products to certain markets and the required collateralization of certain future payment obligations or reserves. Further, if one or more of our corporate debt ratings were downgraded, we may find it more difficult to access the capital markets and we may incur higher borrowing costs.
 In addition, it is possible that a significant lowering of the corporate debt ratings of Loews by certain of the rating agencies could result in an adverse effect on our ratings, independent of any change in our circumstances.
 For further discussion of our ratings, see the Ratings subsection within the Liquidity and Capital Resources section of MD&A in Item 7.
 We are subject to extensive existing state, local, federal and foreign governmental regulations that restrict our ability to do business and generate revenues; additional regulation or significant modification to existing regulations or failure to comply with regulatory requirements may have a materially adverse effect on our business, results of operations and financial condition.
 The insurance industry is subject to comprehensive and detailed regulation and supervision. Most insurance regulations are designed to protect the interests of our policyholders and third-party claimants, rather than our investors. Each jurisdiction in which we do business has established supervisory agencies that regulate the manner in which we do business. Any changes in regulation could impose significant burdens on us. In addition, the Lloyd's marketplace sets rules under which its members, including our Hardy syndicate, operate.
 These rules and regulations relate to, among other things, the standards of solvency (including risk-based capital measures), government-supported backstops for certain catastrophic events (including terrorism), investment restrictions, accounting and reporting methodology, establishment of reserves and potential assessments of funds to settle covered claims against impaired, insolvent or failed private or quasi-governmental insurers. In addition, rules and regulations have recently been introduced, or are being considered, in the areas of information security and ESG, which may also affect our business. We also are subject to numerous regulations governing the protection of personal and confidential information of our clients and employees, including medical records, credit card data and financial information. These laws and regulations, including regulations related to cybersecurity protocols (which continue to evolve in breadth, sophistication and maturity in response to an ever-evolving threat landscape), are increasing in complexity and number, change frequently, sometimes conflict, and could expose us to significant monetary damages, regulatory enforcement actions, fines and/or criminal prosecution in one or more jurisdictions. In response to climate change, regulators at the federal, state and international level also could impose new regulations requiring disclosure of underwriting or investment in certain industry sectors.
 Regulatory powers also extend to premium rate regulations which require that rates not be excessive, inadequate or unfairly discriminatory. State jurisdictions ensure compliance with such regulations through market conduct exams, which may result in losses to the extent non-compliance is ascertained, either as a result of failure to document transactions properly or failure to comply with internal guidelines, or otherwise. The jurisdictions in which we do business may also require us to provide coverage to persons whom we would not otherwise consider eligible or restrict us from withdrawing from unprofitable lines of business or unprofitable market areas. Each jurisdiction dictates the types of insurance and the level of coverage that must be provided to such involuntary risks. Our share of these involuntary risks is mandatory and generally a function of our respective share of the voluntary market by line of insurance in each jurisdiction.

 ITEM 1C. CYBERSECURITY
 CNA's information security and data privacy programs are designed to protect the confidentiality of nonpublic, sensitive personal and business information and the integrity and security of our information systems. These programs include processes that provide guidance for information security decision-making and risk management, and include standards to promote understanding and compliance with applicable laws and regulations. Administrative and technical safeguards that seek to mitigate cybersecurity threats and secure the Company's information assets are also addressed on a risk-based basis. We have designed our enterprise-wide information security programs consistent with industry standards using the National Institute of Standards and Technology Cybersecurity Framework. These programs include processes implemented within our third-party risk management unit designed to identify, mitigate and monitor cybersecurity risk relating to vendors, suppliers and external partners who have access to our confidential information or our information systems. CNA engages both internal auditors and third-party information security experts in connection with reviewing such foregoing processes.
 CNA monitors information security metrics globally. To elevate this information within the organization, our Chief Risk & Reinsurance Officer (CRRO) and Chief Compliance Officer (CCO) present cybersecurity reports and metrics to the Audit Committee of our Board of Directors every quarter. Reports address security events, third-party risk and vulnerabilities, including material risks from cybersecurity threats, and any significant unauthorized occurrences. These discussions are part of our overall enterprise risk management and also take place on at least an annual basis with the full Board of Directors, which is responsible for overseeing material risks, including cybersecurity risk, on an enterprise-wide basis.
 At the senior management level, our Chief Information Security Officer (CISO) oversees CNA's information security and data privacy programs and is responsible for establishing and implementing the security strategy alongside the Chief Information Officer (CIO), to whom the CISO reports directly. The CIO serves on the Enterprise Risk Committee, which is chaired by the CRRO.
 The CISO leads the Information Security group within Information Technology, which manages the controls designed to identify, detect, protect against, respond to and recover from cybersecurity threats and cybersecurity incidents. This group includes a cybersecurity operations team that is responsible for information technology security monitoring and incident response activities, the latter covering the response coordination to cyber-attacks under the leadership and pursuant to the direction of the CISO. The Company engages in a continuous risk monitoring process that seeks to identify the likelihood and impact of internal and external threats to our information security systems and data, and assesses the sufficiency of the controls in place to mitigate these threats to acceptable levels on a risk-based basis. The CISO and CIO together lead efforts to design, implement and operate controls deemed necessary, commensurate with the materiality and criticality of identified risks and the sensitivity of the information assets and systems used throughout the organization. Our current CISO has a bachelor's degree in Computer Information Systems and a master's degree in Cybersecurity, and has over 20 years of experience building and executing information and cybersecurity strategies. Prior to joining CNA, our CIO served in a variety of roles at another major U.S. insurance company, both in business and technology, and has over 20 years of experience working with major U.S. Property & Casualty insurers.
 Threats of security incidents and the impact of actual security incidents are initially assessed and managed by the CISO and CIO as described above. CNA has further implemented response plans that provide the basis for appropriate response to an unauthorized occurrence from a technical perspective, as well as from disclosure and regulatory perspectives.
 These response plans also set forth the processes for internal reporting of a substantive unauthorized occurrence. The CISO reports such matters to the CIO and CCO, who is responsible for convening a team of cross-enterprise leaders to ensure comprehensive responsiveness to an occurrence. This group also analyzes unauthorized occurrences affecting CNA's or third parties' IT systems or sensitive information, and directs the activities of CNA in responding to such incidents.

 In addition, the group, under the leadership of the CCO, undertakes the appropriate internal notifications of any such occurrence, and responsive activities, to the General Counsel, Chief Executive Officer, Chief Financial Officer and Board of Directors.
 To date, no risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, have materially affected or are reasonably likely to materially affect the Company. Please refer to "Any significant interruption in the operation of our business functions, facilities and systems or our vendors' facilities and systems could result in a materially adverse effect on our operations" and "Any significant breach in our data security infrastructure or our vendors' facilities and systems could disrupt business, cause financial losses and damage our reputation, and insurance coverage may not be available for claims related to a breach" under Item 1A Risk Factors.

 ITEM 2. PROPERTIES
 We lease our principal executive offices in Chicago, Illinois, as well as other offices throughout the U.S. We also lease offices in Canada, the U.K., Belgium, Denmark, France, Germany, Italy, Luxembourg and the Netherlands, primarily for branch and insurance business operations in those locations.
 We consider our properties to be in generally good condition and suitable to carry on our business.

 ITEM 3. LEGAL PROCEEDINGS

 OVERVIEW
 The following discussion should be read in conjunction with Part I, Item 1A Risk Factors and Part II, Item 8 Financial Statements and Supplementary Data of this Form 10-K.

 CRITICAL ACCOUNTING ESTIMATES
 The preparation of Consolidated Financial Statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and the amount of revenues and expenses reported during the period. Actual results may differ from those estimates.
 Our Consolidated Financial Statements and accompanying notes have been prepared in accordance with GAAP applied on a consistent basis. We continually evaluate the accounting policies and estimates used to prepare the Consolidated Financial Statements. In general, our estimates are based on historical experience, evaluation of current trends, information from third-party professionals and various other assumptions that are believed to be reasonable under the known facts and circumstances.
 The accounting estimates discussed below are considered by us to be critical to an understanding of our Consolidated Financial Statements as their application places the most significant demands on our judgment. Note A to the Consolidated Financial Statements included under Item 8 should be read in conjunction with this section to assist with obtaining an understanding of the underlying accounting policies related to these estimates. Due to the inherent uncertainties involved with these types of judgments, actual results could differ significantly from our estimates and may have a material adverse impact on our results of operations, financial condition, equity, business, and insurer financial strength and corporate debt ratings.
 Insurance Reserves
 Insurance reserves are established for both short and long-duration insurance contracts. Short-duration contracts are primarily related to property and casualty insurance policies where the reserving process is based on actuarial estimates of the amount of loss, including amounts for known and unknown claims. Long-duration contracts are primarily related to long-term care policies and the reserves are recorded as Future policy benefits reserves as discussed below. The reserve for unearned premiums represents the portion of premiums written related to the unexpired terms of coverage. The reserving process is discussed in further detail in the Reserves - Estimates and Uncertainties section below.
 Long-Term Care Reserves
 Future policy benefits reserves for our long-term care policies are based on certain actuarial assumptions, including morbidity, persistency (inclusive of mortality), anticipated future premium rate increases, and expenses. The adequacy of the reserves is contingent upon actual experience and our future expectations related to these key assumptions. If actual or expected future experience differs from these assumptions, the reserves may not be adequate, requiring us to increase reserves. The reserves are discounted using upper-medium grade fixed income instrument yields as of each reporting date. In addition, we may not receive regulatory approval for the level of premium rate increases we request. The reserving process is discussed in further detail in the Reserves - Estimates and Uncertainties section below.
 Reinsurance and Insurance Receivables
 Exposure exists with respect to the collectibility of ceded property and casualty and life reinsurance to the extent that any reinsurer is unable to meet its obligations or disputes the liabilities we have ceded under reinsurance agreements. An allowance for uncollectible reinsurance is recorded on the basis of periodic evaluations of balances due from reinsurers, reinsurer financial strength rating and solvency, industry experience and current and forecast economic conditions. Further information on our reinsurance receivables is in Note H to the Consolidated Financial Statements included under Item 8.
 Additionally, exposure exists with respect to the collectibility of amounts due from policyholders related to insurance contracts, including amounts due from insureds under high deductible policies and retrospectively rated policies. An allowance for uncollectible insurance receivables is recorded on the basis of periodic

 evaluations of balances due from insureds, currently as well as in the future, historical business default data, management's experience and current and forecast economic conditions.
 If actual experience differs from the estimates made by management in determining the allowances for uncollectible reinsurance and insurance receivables, net receivables as reflected on our Consolidated Balance Sheets may not be collected. Further information on our process for determining the allowances for uncollectible reinsurance and insurance receivables is in Note A to the Consolidated Financial Statements included under Item 8.
 Valuation of Investments and Impairment of Securities
 Our fixed maturity and equity securities are carried at fair value on the balance sheet. Fair value represents the price that would be received in a sale of an asset in an orderly transaction between market participants on the measurement date, the determination of which may require us to make a significant number of assumptions and judgments. Securities with the greatest level of subjectivity around valuation are those that rely on inputs that are significant to the estimated fair value and that are not observable in the market or cannot be derived principally from or corroborated by observable market data. These unobservable inputs are based on assumptions consistent with what we believe other market participants would use to price such securities. Further information on our fair value measurements is in Note C to the Consolidated Financial Statements included under Item 8.
 Our fixed maturity securities are subject to market declines below amortized cost that may result in the recognition of impairment losses in earnings. Factors considered in the determination of whether or not an impairment loss is recognized in earnings include a current intention or need to sell the security or an indication that a credit loss exists. Significant judgment is required in the determination of whether a credit loss has occurred for a security. We consider all available evidence when determining whether a security requires a credit allowance to be recorded, including the financial condition and expected near-term and long-term prospects of the issuer, whether the issuer is current with interest and principal payments, credit ratings on the security or changes in ratings over time, general market conditions, industry, sector or other specific factors and whether we expect to receive cash flows sufficient to recover the entire amortized cost basis of the security.
 Our mortgage loan portfolio is subject to the expected credit loss model, which requires immediate recognition of estimated credit losses over the life of the asset and the presentation of the asset at the net amount expected to be collected. Significant judgment is required in the determination of estimated credit losses and any changes in our expectation of the net amount to be collected are recognized in earnings.
 Further information on our process for evaluating impairments and expected credit losses is in Note A to the Consolidated Financial Statements included under Item 8.

 RESERVES - ESTIMATES AND UNCERTAINTIES
 The level of reserves we maintain represents our best estimate, as of a particular point in time, of what the ultimate settlement and administration of claims will cost based on our assessment of facts and circumstances known at that time. Reserves are not an exact calculation of liability but instead are complex estimates that we derive, generally utilizing a variety of actuarial reserve estimation techniques, from numerous assumptions and expectations about future events, both internal and external, many of which are highly uncertain. As noted below, we review our reserves for each segment of our business periodically, and any such review could result in the need to increase reserves in amounts which could be material and could adversely affect our results of operations, equity, business and insurer financial strength and corporate debt ratings. Further information on reserves is provided in Note E and F to the Consolidated Financial Statements included under Item 8.
 Property and Casualty Claim and Claim Adjustment Expense Reserves
 We maintain loss reserves to cover our estimated ultimate unpaid liability for claim and claim adjustment expenses, including the estimated cost of the claims adjudication process, for claims that have been reported but not yet settled (case reserves) and claims that have been incurred but not reported (IBNR). IBNR includes a provision for development on known cases as well as a provision for late reported incurred claims. Claim and claim adjustment expense reserves are reflected as liabilities and are included on the Consolidated Balance Sheets under the heading "Insurance Reserves." Adjustments to prior year reserve estimates, if necessary, are reflected in results of operations in the period that the need for such adjustments is determined. The carried case and IBNR reserves as of each balance sheet date are provided in the Segment Results section of this MD&A and in Note E to the Consolidated Financial Statements included under Item 8.
 As discussed in the Risk Factors discussion within Item 1A, there is a risk that our recorded reserves are insufficient to cover our estimated ultimate unpaid liability for claims and claim adjustment expenses. Unforeseen emerging or potential claims and coverage issues are also difficult to predict and could materially adversely affect the adequacy of our claim and claim adjustment expense reserves and could lead to future reserve increases.
 In addition, our property and casualty insurance subsidiaries also have actual and potential exposures related to A&EP claims, which could result in material losses. To mitigate the risks posed by our exposure to A&EP claims and claim adjustment expenses, we completed a transaction with NICO under which substantially all of our legacy A&EP liabilities were ceded to NICO effective January 1, 2010. See Note E to the Consolidated Financial Statements included under Item 8 for further discussion about the transaction with NICO, its impact on our results of operations and the deferred retroactive reinsurance gains and the amount of remaining reinsurance limit.
 Establishing Property & Casualty Reserve Estimates
 In developing claim and claim adjustment expense reserve estimates, our actuaries perform detailed reserve analyses that are staggered throughout the year. The data is organized at a reserve group level. A reserve group typically can be a line of business covering a subset of insureds such as commercial automobile liability for small or middle market customers or it can be a particular type of claim such as construction defect. Every reserve group is reviewed at least once during the year, but most are reviewed more frequently. The analyses generally review losses gross of ceded reinsurance and apply the ceded reinsurance terms to the gross estimates to establish estimates net of reinsurance. In addition to the detailed analyses, we review actual loss emergence for all products each quarter.
 Most of our business can be characterized as long-tail. For long-tail business, it will generally be several years between the time the business is written and the time when all claims are settled. Our long-tail exposures include commercial automobile liability, workers' compensation, general liability, medical professional liability, other professional liability and management liability coverages, assumed reinsurance run-off and products liability. Short-tail exposures include property, commercial automobile physical damage, marine, surety and

 warranty. Specialty, Commercial and International contain both long-tail and short-tail exposures. Corporate & Other contains run-off long-tail exposures.
 Various methods are used to project ultimate losses for both long-tail and short-tail exposures.
 The paid development method estimates ultimate losses by reviewing paid loss patterns and applying them to accident or policy years with further expected changes in paid losses. Selection of the paid loss pattern may require consideration of several factors, including the impact of economic, social and medical inflation on claim costs, the rate at which claims professionals make claim payments and close claims, the impact of judicial decisions, the impact of underwriting changes, the impact of large claim payments and other factors. Claim cost inflation itself may require evaluation of changes in the cost of repairing or replacing property, changes in the cost of medical care, changes in the cost of wage replacement, judicial decisions, legislative changes and other factors. Because this method assumes that losses are paid at a consistent rate, changes in any of these factors can affect the results. Since the method does not rely on case reserves, it is not directly influenced by changes in their adequacy.
 For many reserve groups, paid loss data for recent periods may be too immature or erratic for accurate predictions. This situation often exists for long-tail exposures. In addition, changes in the factors described above may result in inconsistent payment patterns. Finally, estimating the paid loss pattern subsequent to the most mature point available in the data analyzed often involves considerable uncertainty for long-tail products such as workers' compensation.
 The incurred development method is similar to the paid development method, but it uses case incurred losses instead of paid losses. Since the method uses more data (case reserves in addition to paid losses) than the paid development method, the incurred development patterns may be less variable than paid patterns. However, selection of the incurred loss pattern typically requires analysis of all of the same factors described above. In addition, the inclusion of case reserves can lead to distortions if changes in case reserving practices have taken place, and the use of case incurred losses may not eliminate the issues associated with estimating the incurred loss pattern subsequent to the most mature point available.
 The loss ratio method multiplies earned premiums by an expected loss ratio to produce ultimate loss estimates for each accident or policy year. This method may be useful for immature accident or policy periods or if loss development patterns are inconsistent, losses emerge very slowly or there is relatively little loss history from which to estimate future losses. The selection of the expected loss ratio typically requires analysis of loss ratios from earlier accident or policy years or pricing studies and analysis of inflationary trends, frequency trends, rate changes, underwriting changes and other applicable factors.
 The Bornhuetter-Ferguson method using paid loss is a combination of the paid development method and the loss ratio method. This method normally determines expected loss ratios similar to the approach used to estimate the expected loss ratio for the loss ratio method and typically requires analysis of the same factors described above. This method assumes that future losses will develop at the expected loss ratio level. The percent of paid loss to ultimate loss implied from the paid development method is used to determine what percentage of ultimate loss is yet to be paid. The use of the pattern from the paid development method typically requires consideration of the same factors listed in the description of the paid development method. The estimate of losses yet to be paid is added to current paid losses to estimate the ultimate loss for each year. For long-tail lines, this method will react very slowly if actual ultimate loss ratios are different from expectations due to changes not accounted for by the expected loss ratio calculation.
 The Bornhuetter-Ferguson method using incurred loss is similar to the Bornhuetter-Ferguson method using paid loss except that it uses case incurred losses. The use of case incurred losses instead of paid losses can result in development patterns that are less variable than paid patterns. However, the inclusion of case reserves can lead to distortions if changes in case reserving have taken place, and the method typically requires analysis of the same factors that need to be reviewed for the loss ratio and incurred development methods.

 The frequency times severity method multiplies a projected number of ultimate claims by an estimated ultimate average loss for each accident or policy year to produce ultimate loss estimates. Since projections of the ultimate number of claims are often less variable than projections of ultimate loss, this method can provide more reliable results for reserve groups where loss development patterns are inconsistent or too variable to be relied on exclusively. In addition, this method can more directly account for changes in coverage that affect the number and size of claims. However, this method can be difficult to apply to situations where very large claims or a substantial number of unusual claims result in volatile average claim sizes. Projecting the ultimate number of claims may require analysis of several factors, including the rate at which policyholders report claims to us, the impact of judicial decisions, the impact of underwriting changes and other factors. Estimating the ultimate average loss may require analysis of the impact of large losses and claim cost trends based on changes in the cost of repairing or replacing property, changes in the cost of medical care, changes in the cost of wage replacement, judicial decisions, legislative changes and other factors.
 Stochastic modeling produces a range of possible outcomes based on varying assumptions related to the particular reserve group being modeled. For some reserve groups, we use models which rely on historical development patterns at an aggregate level, while other reserve groups are modeled using individual claim variability assumptions supplied by the claims department. In either case, multiple simulations using varying assumptions are run and the results are analyzed to produce a range of potential outcomes. The results will typically include a mean and percentiles of the possible reserve distribution which aid in the selection of a point estimate.
 For many exposures, especially those that can be considered long-tail, a particular accident or policy year may not have a sufficient volume of paid losses to produce a statistically reliable estimate of ultimate losses. In such a case, our actuaries typically assign more weight to the incurred development method than to the paid development method. As claims continue to settle and the volume of paid loss increases, the actuaries may assign additional weight to the paid development method. For most of our products, even the incurred losses for accident or policy years that are early in the claim settlement process will not be of sufficient volume to produce a reliable estimate of ultimate losses. In these cases, we may not assign much, if any, weight to the paid and incurred development methods. We may use the loss ratio, Bornhuetter-Ferguson and/or frequency times severity methods. For short-tail exposures, the paid and incurred development methods can often be relied on sooner, primarily because our history includes a sufficient number of years to cover the entire period over which paid and incurred losses are expected to change. However, we may also use the loss ratio, Bornhuetter-Ferguson and/or frequency times severity methods for short-tail exposures.
 For other more complex reserve groups where the above methods may not produce reliable indications, we use additional methods tailored to the characteristics of the specific situation.
 Periodic Reserve Reviews
 The reserve analyses performed by our actuaries result in point estimates. Each quarter, the results of the detailed reserve reviews are summarized and discussed with senior management to determine the best estimate of reserves. Senior management considers many factors in making this decision. Our recorded reserves reflect our best estimate as of a particular point in time based upon known facts and circumstances, consideration of the factors cited above and our judgment. The carried reserve differs from the actuarial point estimate as discussed further below.
 Currently, our recorded reserves are modestly higher than the actuarial point estimate. For Commercial, Specialty and International, the difference between our reserves and the actuarial point estimate is primarily driven by uncertainty with respect to immature accident years, claim cost inflation, changes in claims handling, changes to the tort environment which may adversely affect claim costs and the effects from the economy. For Corporate & Other, the difference between our reserves and the actuarial point estimate is primarily driven by the potential tail volatility of run-off exposures.

 The key assumptions fundamental to the reserving process are often different for various reserve groups and accident or policy years. Some of these assumptions are explicit assumptions that are required of a particular method, but most of the assumptions are implicit and cannot be precisely quantified. An example of an explicit assumption is the pattern employed in the paid development method. However, the assumed pattern is itself based on several implicit assumptions such as the impact of inflation on medical costs and the rate at which claim professionals close claims. As a result, the effect on reserve estimates of a particular change in assumptions typically cannot be specifically quantified, and changes in these assumptions cannot be tracked over time.
 Our recorded reserves are management's best estimate. In order to provide an indication of the variability associated with our net reserves, the following discussion provides a sensitivity analysis that shows the approximate estimated impact of variations in significant factors affecting our reserve estimates for particular types of business. These significant factors are the ones that we believe could most likely materially affect the reserves. This discussion covers the major types of business for which we believe a material deviation to our reserves is reasonably possible. There can be no assurance that actual experience will be consistent with the current assumptions or with the variation indicated by the discussion. In addition, there can be no assurance that other factors and assumptions will not have a material impact on our reserves.
 The three areas for which we believe a significant deviation to our net reserves is reasonably possible are (i) professional liability, management liability and surety products; (ii) workers' compensation; and (iii) general liability.
 Professional liability, management liability and surety products include US professional liability coverages provided to various professional firms, including architects, real estate agents, small and mid-sized accounting firms, law firms and other professional firms. They also include directors and officers (D&O), errors and omissions (E&O), employment practices, fiduciary, fidelity, cyber and surety coverages, and medical liability. The most significant factor affecting reserve estimates for these liability coverages is claim severity. Claim severity is driven by the cost of medical care, the cost of wage replacement, legal fees, judicial decisions, legislative changes and other factors. Underwriting and claim handling decisions, such as the classes of business written and individual claim settlement decisions, can also affect claim severity. If the estimated claim severity increases by 9%, we estimate that net reserves would increase by approximately $500 million. If the estimated claim severity decreases by 3%, we estimate that net reserves would decrease by approximately $150 million. Our net reserves for these products were approximately $5.7 billion as of December 31, 2023.
 For workers' compensation, since many years will pass from the time the business is written until all claim payments have been made, the most significant factor affecting workers' compensation reserve estimates is claim cost inflation on claim payments. Workers' compensation claim cost inflation is driven by the cost of medical care, the cost of wage replacement, expected claimant lifetimes, judicial decisions, legislative changes and other factors. If estimated workers' compensation claim cost inflation increases by 100 basis points for the entire period over which claim payments will be made, we estimate that our net reserves would increase by approximately $250 million. If estimated workers' compensation claim cost inflation decreases by 100 basis points for the entire period over which claim payments will be made, we estimate that our net reserves would decrease by approximately $250 million. Our net reserves for workers' compensation were approximately $3.6 billion as of December 31, 2023.
 For general liability, the most significant factor affecting reserve estimates is claim severity. Claim severity is driven by changes in the cost of repairing or replacing property, the cost of medical care, the cost of wage replacement, judicial decisions, legislation and other factors. If the estimated claim severity for general liability increases by 6%, we estimate that our net reserves would increase by approximately $250 million. If the estimated claim severity for general liability decreases by 3%, we estimate that our net reserves would decrease by approximately $150 million. Our net reserves for general liability were approximately $4.2 billion as of December 31, 2023.

 Given the factors described above, it is not possible to quantify precisely the ultimate exposure represented by claims and related litigation. As a result, we regularly review the adequacy of our reserves and reassess our reserve estimates as historical loss experience develops, additional claims are reported and settled and additional information becomes available in subsequent periods. In reviewing our reserve estimates, we make adjustments in the period that the need for such adjustments is determined. These reviews have resulted in our identification of information and trends that have caused us to change our reserves in prior periods and could lead to our identification of a need for additional material increases or decreases in claim and claim adjustment expense reserves, which could materially affect our results of operations, equity, business and insurer financial strength and corporate debt ratings positively or negatively. See discussion within Note E to the Consolidated Financial Statements included under Item 8 for additional information about reserve development and the Ratings section of this MD&A for further information regarding our financial strength and corporate debt ratings.
 Life & Group Policyholder Reserves
 Our Life & Group segment includes our run-off long-term care business as well as structured settlement obligations not funded by annuities related to certain property and casualty claimants. Long-term care policies may provide benefits for nursing homes, assisted living facilities and home health care subject to various daily and lifetime caps. Generally, policyholders must continue to make periodic premium payments to keep the policy in force and we have the ability to increase policy premiums, subject to state regulatory approval.
 We maintain future policy benefit reserves for our long-term care policies. Future policy benefit reserves for long-term care policies relate to policyholders that are currently receiving benefits, including claims that have been incurred but are not yet reported, as well as policyholders that are not yet receiving benefits. In developing the future policy benefit reserves, our actuaries perform a reserve review on an annual basis. During the annual review, historical policyholder morbidity, persistency (inclusive of mortality), anticipated future premium rate increases and expense experience is reviewed and compared to the current best estimate actuarial assumption set for potential revision. On a quarterly basis, our actuaries perform experience studies that monitor the appropriateness of best estimate actuarial assumptions against emerging experience to assess whether any updates to those assumptions are warranted. The determination of these reserves requires management to make estimates and assumptions about expected policyholder experience over the remaining life of the policies. Since policies may be in force for several decades, these assumptions are subject to significant estimation risk.
 In addition, claim and claim adjustment expense reserves are maintained for our structured settlement obligations. In developing the claim and claim adjustment expense reserve estimates for our structured settlement obligations, our actuaries monitor mortality and expense experience on an annual basis. Our recorded claim and claim adjustment expense reserves reflect management's best estimate after incorporating the results of the most recent reviews. Claim and claim adjustment expense reserves for structured settlement obligations are discounted as discussed in Note A to the Consolidated Financial Statements included under Item 8.
 The actuarial assumptions related to future policy benefit reserves for long-term care policies that management believes are subject to the most variability are morbidity, persistency and anticipated future premium rate increases. Morbidity is the frequency and severity of injury, illness, sickness and diseases contracted. Persistency is the percentage of policies remaining in force and can be affected by policy lapses, benefit reductions and death. Future premium rate increases are generally subject to regulatory approval, and therefore the exact timing and size of the approved rate increases are unknown. As a result of this variability, our long-term care reserves may be subject to material increases if actual experience develops adversely to our expectations.

 The table below summarizes the estimated pretax impact on our results of operations from various hypothetical revisions to our liability for future policyholder benefits (LFPB) reserve assumptions. We have assumed that revisions to such assumptions would occur in each policy type, age and duration within each policy group. The impact of each sensitivity is discrete and does not reflect the impact one factor may have on another or the mitigating impact from management actions, which may include additional future premium rate increases. Although such hypothetical revisions are not currently required or anticipated, we believe they could occur based on past variances in experience and our expectations of the ranges of future experience that could reasonably occur. Any actual adjustment would be dependent on the specific policies affected and, therefore, may differ from the estimates summarized below. The estimated impacts to results of operations in the table below are after consideration of any net premium ratio impacts.

 As part of the annual reserve review, statutory long-term care reserve adequacy is evaluated via premium deficiency testing, by comparing carried statutory reserves with our best estimate reserves, which incorporates best estimate discount rate and liability assumptions in its determination. Statutory margin is the excess of carried reserves over best estimate reserves. As of September 30, 2023, statutory long-term care margin increased to $1.3 billion, primarily driven by a more favorable interest rate environment resulting in a higher yielding investment portfolio.

 CATASTROPHES AND RELATED REINSURANCE
 Various events can cause catastrophe losses. These events can be natural or man-made, including hurricanes, tornadoes, windstorms, earthquakes, hail, severe winter weather, fires, floods, riots, strikes, civil unrest, cyber-attacks, pandemics and acts of terrorism that produce unusually large aggregate losses. In most, but not all cases, our catastrophe losses from these events in the United States of America (U.S.) are defined consistent with the definition of the Property Claims Service (PCS). PCS defines a catastrophe as an event that causes damage of $25 million or more in direct insured losses to property and affects a significant number of policyholders and insurers. For events outside of the U.S., we define a catastrophe as an industry recognized event that generates an accumulation of claims amounting to more than $1 million for the International segment.
 Catastrophes are an inherent risk of the property and casualty insurance business and have contributed to material period-to-period fluctuations in our results of operations and/or equity. We reported catastrophe losses, net of reinsurance, of $236 million and $247 million for the years ended December 31, 2023 and 2022. Catastrophe losses for the years ended December 31, 2023 and 2022 were driven by severe weather related events, primarily Winter Storm Elliott and Hurricane Ian for 2022.
 We use various analyses and methods, including using one of the industry standard natural catastrophe models, to estimate hurricane and earthquake losses at various return periods and to inform underwriting and reinsurance decisions designed to manage our exposure to catastrophic events. We generally seek to manage our exposure through the purchase of catastrophe reinsurance and utilize various reinsurance programs to mitigate catastrophe losses, including excess-of-loss occurrence and aggregate treaties covering property and workers' compensation, a property quota share treaty and the Terrorism Risk Insurance Program Reauthorization Act of 2019 (TRIPRA), as well as individual risk agreements that reinsure from losses from specific classes or lines of business. We conduct an ongoing review of our risk and catastrophe reinsurance coverages and from time to time make changes as we deem appropriate.
 The following discussion summarizes our most significant catastrophe reinsurance coverage at January 1, 2024.
 Group North American Property Treaty
 We purchased corporate catastrophe excess-of-loss treaty reinsurance covering our U.S. states and territories and Canadian property exposures underwritten in our North American and European companies. Exposures underwritten through Hardy are excluded and covered under a separate treaty. The treaty has a term of June 1, 2023 to June 1, 2024 and provides coverage for the accumulation of covered losses from catastrophe occurrences above our per occurrence retention of $235 million up to $1.1 billion for all losses other than earthquakes. Earthquakes are covered up to $1.2 billion. Losses stemming from terrorism events are covered unless they are due to a nuclear, biological or chemical attack. All layers of the treaty provide for one full reinstatement.
 Group Workers' Compensation Treaty
 We also purchased corporate Workers' Compensation catastrophe excess-of-loss treaty reinsurance for the period January 1, 2024 to January 1, 2025 providing $275 million of coverage for the accumulation of covered losses related to natural catastrophes above our per occurrence retention of $25 million. The treaty also provides $775 million of coverage for the accumulation of covered losses related to terrorism events above our per occurrence retention of $25 million. Of the $775 million in terrorism coverage, $200 million is provided for nuclear, biological chemical and radiation events. One full reinstatement is available for the first $275 million above the retention, regardless of the covered peril.
 Terrorism Risk Insurance Program Reauthorization Act of 2019
 Our principal reinsurance protection against large-scale terrorist attacks, including nuclear, biological, chemical or radiological attacks, is the coverage currently provided through TRIPRA which runs through the end of 2027. TRIPRA provides a U.S. government backstop for insurance-related losses resulting from any "act of terrorism," which is certified by the Secretary of Treasury in consultation with the Secretary of Homeland Security for losses that exceed a threshold of $200 million industry-wide for the calendar year 2024. Under the current provisions of the program, in 2024, the federal government will reimburse 80% of our covered losses in excess of our applicable deductible up to a total industry program cap of $100 billion. Our deductible is based

 on eligible commercial property and casualty earned premiums for the preceding calendar year. Based on 2023 earned premiums, our estimated deductible under the program is $1.1 billion for 2024. If an act of terrorism or acts of terrorism result in covered losses exceeding the $100 billion annual industry aggregate limit, Congress would be responsible for determining how additional losses in excess of $100 billion will be paid.

 (1) As of January 1, 2023, we adopted ASU 2018-12 using the modified retrospective method applied as of the transition date of January 1, 2021. Prior period amounts presented in the financial statements have been adjusted to reflect application of the new guidance. See Note A to the Consolidated Financial Statements for additional information.
 Core income increased $448 million in 2023 as compared with 2022. Core income for our Property & Casualty Operations increased $265 million driven by higher net investment income and improved underwriting results. Core loss for our Life & Group segment decreased $173 million, while core loss for our Corporate & Other segment decreased $10 million.
 Catastrophe losses were $236 million in 2023, primarily driven by severe weather related events. Catastrophe losses were $247 million in 2022, primarily related to Winter Storm Elliott and Hurricane Ian. Unfavorable net prior year loss reserve development of $48 million was recorded in 2023 as compared with favorable net prior year loss reserve development of $32 million in 2022 related to our Specialty, Commercial, International and Corporate & Other segments. Further information on net prior year loss reserve development is in Note E to the Consolidated Financial Statements included under Item 8.

 2022 Compared with 2021
 Core income decreased $252 million in 2022 as compared with 2021. Core income for our Property & Casualty Operations increased $56 million primarily due to improved underwriting results and higher net investment income from fixed income securities partially offset by lower investment income from limited partnerships and common stock. Core results for our Life & Group segment decreased $329 million, while core loss for our Corporate & Other segment decreased $21 million.
 Catastrophe losses were $247 million in 2022 as compared with $397 million in 2021. Catastrophe losses for the years ended December 31, 2022 and 2021 were driven by severe weather related events, primarily Winter Storm Elliott and Hurricane Ian for 2022 and Hurricane Ida and Winter Storms Uri and Viola for 2021.
 Favorable net prior year loss reserve development of $32 million was recorded in 2022 as compared with unfavorable net prior year loss reserve development of $11 million in 2021 related to our Specialty, Commercial, International and Corporate & Other segments. Further information on net prior year loss reserve development is in Note E to the Consolidated Financial Statements included under Item 8.

 SEGMENT RESULTS
 The following discusses the results of operations for our business segments.
 Our property and casualty commercial insurance operations are managed and reported in three business segments: Specialty, Commercial and International, which we refer to collectively as Property & Casualty Operations. Specialty provides management and professional liability and other coverages through property and casualty products and services using a network of brokers, independent agencies and managing general underwriters. Commercial works with a network of brokers and independent agents to market a broad range of property and casualty insurance products to all types of insureds targeting small business, construction, middle markets and other commercial customers. The International segment underwrites property and casualty coverages on a global basis through a branch operation in Canada, a European business consisting of insurance companies based in the U.K. and Luxembourg and Hardy, our Lloyd's syndicate.
 Our operations outside of Property & Casualty Operations are managed and reported in two segments: Life & Group and Corporate & Other. Life & Group primarily includes the results of our long-term care business that is in run-off. Corporate & Other primarily includes certain corporate expenses, including interest on corporate debt, and the results of certain property and casualty businesses in run-off, including CNA Re, A&EP, a legacy portfolio of excess workers' compensation (EWC) policies and certain legacy mass tort reserves. Intersegment eliminations are also included in this segment.
 We utilize the core income (loss) financial measure to monitor our operations. Core income (loss) is calculated by excluding from net income (loss) the after-tax effects of net investment gains or losses. The calculation of core income (loss) excludes net investment gains or losses because net investment gains or losses are generally driven by economic factors that are not necessarily reflective of our primary operations. Management monitors core income (loss) for each business segment to assess segment performance. Presentation of consolidated core income (loss) is deemed to be a non-GAAP financial measure and management believes some investors may find this measure useful to evaluate our primary operations. See further discussion regarding how we manage our business and reconciliations of non-GAAP measures to the most comparable GAAP measures and other information in Note P to the Consolidated Financial Statements included under Item 8.
 In evaluating the results of our Specialty, Commercial and International segments, we utilize the loss ratio, the underlying loss ratio, the expense ratio, the dividend ratio, the combined ratio and the underlying combined ratio. These ratios are calculated using GAAP financial results. The loss ratio is the percentage of net incurred claim and claim adjustment expenses to net earned premiums. The underlying loss ratio excludes the impact of catastrophe losses and development-related items from the loss ratio. Development-related items represents net prior year loss reserve and premium development, and includes the effects of interest accretion and change in allowance for uncollectible reinsurance and deductible amounts. The expense ratio is the percentage of insurance underwriting and acquisition expenses, including the amortization of deferred acquisition costs, to net earned premiums. The dividend ratio is the ratio of policyholders' dividends incurred to net earned premiums. The combined ratio is the sum of the loss, expense and dividend ratios. The underlying combined ratio is the sum of the underlying loss ratio, the expense ratio and the dividend ratio. In addition, we also utilize renewal premium change, rate, retention and new business in evaluating operating trends. Renewal premium change represents the estimated change in average premium on policies that renew, including rate and exposure changes. Rate represents the average change in price on policies that renew excluding exposure change. Exposure represents the measure of risk used in the pricing of the insurance product. The change in exposure represents the change in premium dollars on policies that renew as a result of the change in risk of the policy. Retention represents the percentage of premium dollars renewed, excluding rate and exposure changes, in comparison to the expiring premium dollars from policies available to renew. New business represents premiums from policies written with new customers and additional policies written with existing customers. Gross written premiums, excluding third-party captives, excludes business which is ceded to third-party captives, including business related to large warranty programs. We use underwriting gain (loss), calculated using GAAP financial results, to monitor our insurance operations. Underwriting gain (loss) is pretax and is calculated as net earned premiums less total insurance expenses, which includes insurance claims and policyholders' benefits, amortization of deferred acquisition costs and other insurance related expenses. Underlying underwriting gain (loss) represents underwriting results excluding catastrophe losses and development-related items.
 Changes in estimates of claim and claim adjustment expense reserves, net of reinsurance, for prior years are defined as net prior year loss reserve development within this MD&A. These changes can be favorable or

 unfavorable. Net prior year loss reserve development does not include the effect of any related acquisition expenses. Further information on our reserves is provided in Note E and Note F to the Consolidated Financial Statements included under Item 8.

 Gross written premiums, excluding third-party captives, for Specialty decreased $14 million in 2023 as compared with 2022 driven by lower new business partially offset by strong retention. Net written premiums for Specialty increased $23 million in 2023 as compared with 2022. The increase in net earned premiums was consistent with the trend in net written premiums.
 Core income increased $40 million in 2023 as compared with 2022 primarily due to higher net investment income partially offset by lower favorable net prior year loss reserve development, lower underlying underwriting results and lower income from non-insurance warranty business.
 The combined ratio of 90.4% increased 1.8 point in 2023 as compared with 2022 primarily due to a 1.0 point increase in the expense ratio and a 0.8 point increase in the loss ratio. The increase in the expense ratio was driven by higher employee related and acquisition costs. The increase in the loss ratio was largely due to lower favorable net prior year loss reserve development. There were no catastrophe losses for 2023, as compared with $2 million, or 0.1 points of the loss ratio, for 2022.
 Favorable net prior year loss reserve development of $14 million and $40 million was recorded in 2023 and 2022. Further information on net prior year loss reserve development is in Note E to the Consolidated Financial Statements included under Item 8.

 Gross written premiums for Commercial increased $950 million in 2023 as compared with 2022 driven by higher new business and rate. Net written premiums for Commercial increased $687 million in 2023 as compared with 2022. The increase in net earned premiums was consistent with the trend in net written premiums.
 Core income increased $186 million in 2023 as compared with 2022, driven by higher net investment income and improved current accident year underwriting results partially offset by lower favorable net prior year loss reserve development.
 The combined ratio of 96.0% improved 1.3 points in 2023 as compared with 2022 due to a 0.8 point improvement in the expense ratio and a 0.5 improvement in the loss ratio. The improvement in the expense ratio was driven by higher net earned premiums partially offset by higher employee related costs. The improvement in the loss ratio was driven by lower catastrophe losses partially offset by lower favorable net prior year loss reserve development. Catastrophe losses were $207 million, or 4.5 points of the loss ratio, for 2023, as compared with $222 million, or 5.6 points of the loss ratio, for 2022.

 Gross written premiums for International increased $91 million in 2023 as compared with 2022. Excluding the effect of foreign currency exchange rates, gross written premiums increased $102 million driven by favorable renewal premium change. Net written premiums for International increased $73 million in 2023 as compared with 2022. Excluding the effect of foreign currency exchange rates, net written premiums increased $74 million as compared with 2022. The increase in net earned premiums was consistent with the trend in net written premiums.
 Core income increased $39 million in 2023 as compared with 2022 driven by higher net investment income, improved underlying underwriting results and a favorable impact from changes in foreign currency exchange rates, partially offset by unfavorable net prior year loss reserve development.

 The combined ratio of 92.6% increased 0.8 points in 2023 as compared with 2022 due to a 1.9 point increase in the loss ratio partially offset by a 1.1 point improvement in the expense ratio. The increase in the loss ratio was driven by unfavorable net prior year loss reserve development of $13 million recorded for 2023 compared to favorable net prior year loss reserve development of $13 million recorded for 2022. Catastrophe losses were $29 million, or 2.5 points of the loss ratio, for 2023, as compared with $23 million, or 2.2 points of the loss ratio, for 2022. The improvement in the expense ratio was driven by higher net earned premiums and a favorable reinsurance acquisition related catch-up adjustment in the third quarter of 2023, partially offset by higher employee related costs.
 Further information on net prior year loss reserve development is in Note E to the Consolidated Financial Statements included under Item 8.

 (1) As of January 1, 2023, we adopted ASU 2018-12 using the modified retrospective method applied as of the transition date of January 1, 2021. Prior period amounts presented in the financial statements have been adjusted to reflect application of the new guidance. See Note A and Note F to the Consolidated Financial Statements for additional information.
 Core loss decreased $173 million in 2023 as compared with 2022 primarily due to higher net investment income and an unfavorable pretax impact of $181 million in the prior year as a result of the annual reserve reviews, partially offset by long-term care policy buyouts in 2023. Policy buyouts generally result in an unfavorable impact on core loss, as the cash payments are linked to higher statutory reserve levels. Excluding the impacts of long-term care policy buyouts, 2023 underwriting results are generally in line with reserving expectations.
 Both years are inclusive of cash flow assumption updates as a result of the annual reserve review completed in the third quarter of each year. Cash flow assumption updates for 2023 resulted in an $8 million pretax increase in long-term care reserves. Adjusted to reflect the application of the LDTI accounting standard, the cash flow assumption updates for 2022 resulted in a $186 million pretax increase in long-term care reserves, primarily driven by the unfavorable impact of increased cost of care inflation, partially offset by favorable premium rate assumptions.
 The annual structured settlement review resulted in a pretax reduction in claim reserves of $6 million and $5 million for 2023 and 2022.
 2022 Compared with 2021
 Results for both years have been adjusted to reflect the application of the LDTI accounting standard.
 Core results decreased $329 million in 2022 as compared with 2021 primarily due to the unfavorable impact of the 2022 annual reserve reviews and lower net investment income.
 Cash flow assumption updates, as a result of the annual reserve reviews, for 2022 resulted in an $186 million pretax increase in long-term care reserves compared to a $3 million pretax increase in 2021.
 The annual structured settlement review resulted in a pretax reduction in claim reserves of $5 million for 2022 and a pretax increase to claim reserves of $2 million for 2021.

The charge related to office consolidation is further discussed in Note M and net prior year loss reserve development is further discussed in Note E, to the Consolidated Financial Statements included under Item 8.
 The application of retroactive reinsurance accounting to additional cessions to the A&EP LPT resulted in an after-tax benefit of $6 million and $3 million in 2023 and 2022, both of which have no economic impact.

 Commercial Real Estate
 Our investment portfolio has exposure to the commercial real estate sector primarily through our fixed maturity securities and mortgage loan portfolios. The performance of these assets is dependent on a number of factors, including the performance of the underlying collateral (which is influenced by cash flows from underlying property leases), changes in the fair value of collateral, refinancing risk, and the creditworthiness of tenants of credit tenant loan properties (where lease payments directly service the loan).
 Within our fixed maturity securities portfolio, our exposure is primarily through our commercial mortgage-backed securities portfolio and our corporate and other bonds portfolio, which contains obligations of real estate investment trust (REIT) issuers. Commercial mortgage-backed securities include both single asset, single borrower collateral that is securitized independently and conduit collateral that is securitized in diversified pools.

 Mortgage loans are commercial in nature and are carried at unpaid principal balance, net of unamortized fees and an allowance for expected credit losses. The allowance for expected credit losses is developed by assessing the credit quality of pools of mortgage loans in good standing using debt service coverage ratios (DSCR) and loan-to-value ratios (LTV). This assessment utilizes historical credit loss experience adjusted to reflect current conditions and reasonable and supportable forecasts. As of December 31, 2023 the allowance for expected credit losses on our mortgage portfolio was $35 million, or 3.3% of our amortized cost basis.

 In addition to our mortgage loan portfolio, we invest in securitized credit tenant loans and ground lease financings that are classified as fixed maturity securities and are largely investment grade quality. As of December 31, 2023, these holdings had an estimated fair value of $479 million and net unrealized losses of $87 million.
 We own other fixed maturity securities which have exposure to cell towers, data centers and other collateral types that could be viewed as having real estate characteristics. We view these securities to have risks more akin to operating enterprises that do not share the same risks as the broader commercial real estate market.
 We do not hold any direct investments in commercial real estate. Additionally, we do not have significant exposure through our limited partnership portfolio to funds whose primary strategy is real estate focused.

 Duration
 A primary objective in the management of the investment portfolio is to optimize return relative to the corresponding liabilities and respective liquidity needs. Our views on the current interest rate environment, tax regulations, asset class valuations, specific security issuer and broader industry segment conditions as well as domestic and global economic conditions, are some of the factors that enter into an investment decision. We also continually monitor exposure to issuers of securities held and broader industry sector exposures and may from time to time adjust such exposures based on our views of a specific issuer or industry sector.
 A further consideration in the management of the investment portfolio is the characteristics of the corresponding liabilities and the ability to align the duration of the portfolio to those liabilities and to meet future liquidity needs, minimize interest rate risk and maintain a level of income sufficient to support the underlying insurance liabilities. For portfolios where future liability cash flows are determinable and typically long term in nature, we segregate investments for asset/liability management purposes. The segregated investments support the long-term care and structured settlement liabilities in the Life & Group segment.
 The effective durations of fixed income securities and short-term investments are presented in the following table. Amounts presented are net of payable and receivable amounts for securities purchased and sold, but not yet settled.

 The investment portfolio is periodically analyzed for changes in duration and related price risk. Certain securities have duration characteristics that are variable based on market interest rates, credit spreads and other factors that may drive variability in the amount and timing of cash flows. Additionally, we periodically review the sensitivity of the portfolio to the level of foreign exchange rates and other factors that contribute to market price changes. A summary of these risks and specific analysis on changes is included in the Quantitative and Qualitative Disclosures About Market Risk included under Item 7A.

 LIQUIDITY AND CAPITAL RESOURCES

 Cash Flows
 Our primary operating cash flow sources are premiums and investment income. Our primary operating cash flow uses are payments for claims, policy benefits and operating expenses, including interest expense on corporate debt. Additionally, cash may be paid or received for income taxes.
 For 2023, net cash provided by operating activities was $2,285 million as compared with $2,502 million for 2022. The decrease in cash provided by operating activities was driven by higher net claim payments, which includes long-term care policy buyouts of $193 million, and higher operating expenses partially offset by an increase in premiums collected.
 Cash flows from investing activities include the purchase and disposition of financial instruments, excluding those held as trading, and may include the purchase and sale of businesses, equipment and other assets not generally held for resale.
 For 2023, net cash used by investing activities was $1,843 million as compared with $1,512 million for 2022. Net cash used or provided by investing activities is primarily driven by cash available from operations and by other factors, such as financing activities.
 Cash flows from financing activities may include proceeds from the issuance of debt and equity securities, and outflows for stockholder dividends, repayment of debt and purchases of our common stock.
 For 2023, net cash used by financing activities was $577 million as compared with $1,032 million for 2022. Financing activities for the periods presented include:
 • In 2023, we paid dividends of $787 million and repurchased 550,000 shares of our common stock at an aggregate cost of $24 million.
 • In 2023, we issued $500 million of 5.50% senior notes due June 15, 2033 and repaid the $243 million outstanding aggregate principal balance of our 7.25% debenture which came due November 15, 2023.
 • In 2022, we paid dividends of $982 million and repurchased 890,000 shares of our common stock at an aggregate cost of $39 million.

 Liquidity
 We believe that our present cash flows from operating, investing and financing activities are sufficient to fund our current and expected working capital and debt obligation needs and we do not expect this to change in the near term. There are currently no amounts outstanding under our $250 million senior unsecured revolving credit facility, which was amended and restated during the fourth quarter of 2023, and no borrowings outstanding through our membership in the Federal Home Loan Bank of Chicago (FHLBC). Further information on our Second Amended and Restated Credit Agreement is in Note I to the Consolidated Financial Statements included under Item 8.
 CCC paid dividends of $1,055 million and $990 million to CNAF during 2023 and 2022.
 We have an effective shelf registration statement on file with the Securities and Exchange Commission under which we may publicly issue an unspecified amount of debt, equity or hybrid securities from time to time.

 Common Stock Dividends
 Cash dividends of $ 2.88 per share on our common stock, including a special cash dividend of $1.20 per share, were declared and paid in 2023. On February 2, 2024, our Board of Directors declared a quarterly cash dividend of $0.44 per share and a special cash dividend of $2.00 per share, payable March 7, 2024 to stockholders of record on February 20, 2024. The declaration and payment of future dividends to holders of our common stock will be at the discretion of our Board of Directors and will depend on many factors, including our earnings, financial condition, business needs and regulatory constraints.
 Our ability to pay dividends and satisfy our credit obligations is significantly dependent on receipt of dividends from our subsidiaries. The payment of dividends to us by our insurance subsidiaries without prior approval of the insurance department of each subsidiary's domiciliary jurisdiction is limited by formula. Dividends in excess of these amounts are subject to prior approval by the respective state insurance departments.
 Further information on our dividends from subsidiaries is provided in Note N to the Consolidated Financial Statements included under Item 8.

 Commitments, Contingencies and Guarantees
 We have various commitments, contingencies and guarantees which arose in the ordinary course of business. The impact of these commitments, contingencies and guarantees should be considered when evaluating our liquidity and capital resources.

 Ratings
 Ratings are an important factor in establishing the competitive position of insurance companies. Our insurance company subsidiaries are rated by major rating agencies and these ratings reflect the rating agency's opinion of the insurance company's financial strength, operating performance, strategic position and ability to meet its obligations to policyholders. Agency ratings are not a recommendation to buy, sell or hold any security and may be revised or withdrawn at any time by the issuing organization. Each agency's rating should be evaluated independently of any other agency's rating. One or more of these agencies could take action in the future to change the ratings of our insurance subsidiaries.
 The table below reflects the Insurer Financial Strength Ratings of CNA's insurance company subsidiaries issued by A.M. Best, Moody's, S&P and Fitch. The table also includes the ratings for CNAF's senior debt.

 ACCOUNTING STANDARDS UPDATE
 For a discussion of Accounting Standards, see Note A to the Consolidated Financial Statements included under Item 8.

 RECENT TAX LEGISLATION
 Corporate Alternative Minimum Tax
 The Inflation Reduction Act was enacted on August 16, 2022, and includes, among other provisions, a corporate alternative minimum tax (CAMT) of 15%, effective January 1, 2023, imposed on the adjusted financial statement income (AFSI) of an applicable corporation whose average annual AFSI over three prior years exceeds $1 billion. Based on interpretations of the CAMT and current guidance, we believe that the CAMT has no impact on our financial results for the year ended December 31, 2023. Along with Loews, we will continue to monitor as additional technical guidance from the U.S. Department of Treasury, including forthcoming proposed regulations, becomes available.
 Pillar Two
 The Organization for Economic Co-operation and Development/G20 Inclusive Framework on Base Erosion and Profit Shifting has introduced rules to establish a global minimum corporate tax rate of 15%, commonly referred to as the Pillar Two rules. Numerous foreign countries have enacted legislation to implement the Pillar Two rules, effective beginning in 2024, or are expected to enact similar legislation. We are currently evaluating the potential impacts that Pillar Two may have on future periods and will continue to monitor the implementation of the Pillar Two rules in the jurisdictions in which we operate.

 FORWARD-LOOKING STATEMENTS
 This report contains a number of forward-looking statements which relate to anticipated future events rather than actual present conditions or historical events. These statements are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and generally include words such as "believes," "expects," "intends," "anticipates," "estimates" and similar expressions. Forward-looking statements in this report include any and all statements regarding expected developments in our insurance business, including losses and loss reserves (note that loss reserves for long-term care, A&EP and other mass tort claims are more uncertain, and therefore more difficult to estimate than loss reserves respecting traditional property and casualty exposures); the impact of routine ongoing insurance reserve reviews we conduct; our expectations concerning our revenues, earnings, expenses and investment activities; volatility in investment returns; and our proposed actions in response to trends in our business. Forward-looking statements, by their nature, are subject to a variety of inherent risks and uncertainties that could cause actual results to differ materially from the results projected in the forward-looking statements. We cannot control many of these risks and uncertainties. Material risks and uncertainties are addressed in Part I, Item IA Risk Factors and include, but are not limited to, the following:
 Company-Specific Factors
 • the risks and uncertainties associated with our insurance reserves, as outlined in the Critical Accounting Estimates and the Reserves - Estimates and Uncertainties sections of this report, including the sufficiency of the reserves and the possibility for future increases, which would be reflected in the results of operations in the period that the need for such adjustment is determined;
 • the risk that the other parties to the transactions in which, subject to certain limitations, we ceded our legacy A&EP and EWC liabilities, respectively, will not fully perform their respective obligations to CNA, the uncertainty in estimating loss reserves for A&EP and EWC liabilities and the possible continued exposure of CNA to liabilities for A&EP and EWC claims that are not covered under the terms of the respective transactions; and
 • the performance of reinsurance companies under reinsurance contracts with us.

 Industry and General Market Factors
 • general economic and business conditions, including recessionary conditions that may decrease the size and number of our insurance customers and create losses to our lines of business and inflationary pressures on medical care costs, construction costs and other economic sectors;
 • the effects of social inflation, including frequency of nuclear verdicts and increased litigation activity, on the severity of claims;
 • the effects of reviver statutes that extend, or eliminate, the statute of limitations for the reporting of claims, including statutes passed in certain states with respect to sexual molestation and sexual abuse, on the frequency of claims;
 • the impact of competitive products, policies and pricing and the competitive environment in which we operate, including changes in our book of business;
 • product and policy availability and demand and market responses, including the level of ability to obtain rate increases;
 • the COVID-19 pandemic, including new or emerging variants, other potential pandemics and related measures to mitigate the spread of the foregoing may continue to result in increased claims and related litigation risk across our enterprise;
 • conditions in the capital and credit markets, including uncertainty and instability in these markets, as well as the overall economy, and their impact on the returns, types, liquidity and valuation of our investments;
 • conditions in the capital and credit markets that may limit our ability to raise significant amounts of capital on favorable terms; and
 • the possibility of changes in our ratings by ratings agencies, including the inability to access certain markets or distribution channels and the required collateralization of future payment obligations as a result of such changes, and changes in rating agency policies and practices.
 Regulatory, Legal and Operational Factors
 • regulatory and legal initiatives and compliance with governmental regulations and other legal requirements, which are increasing in complexity and number, change frequently, sometimes conflict, and could expose us to significant monetary damages, regulatory enforcement actions, fines and/or criminal prosecution in one or more jurisdictions, including regulations related to cybersecurity protocols (which continue to evolve in breadth, sophistication and maturity in response to an ever-evolving threat landscape), legal inquiries by state authorities, judicial interpretations within the regulatory framework, including interpretation of policy provisions, decisions regarding coverage and theories of liability, legislative actions that increase claimant activity, including those revising applicability of statutes of limitations, trends in litigation and the outcome of any litigation involving us and rulings and changes in tax laws and regulations;
 • regulatory limitations, impositions and restrictions upon us, including with respect to our ability to increase premium rates, and the effects of assessments and other surcharges for guaranty funds and second-injury funds, other mandatory pooling arrangements and future assessments levied on insurance companies;
 • regulatory limitations and restrictions, including limitations upon our ability to receive dividends from our insurance subsidiaries, imposed by regulatory authorities, including regulatory capital adequacy standards;
 • breaches of our or our vendors' data security infrastructure resulting in unauthorized access to systems and information, and/or interruption of operations; and
 • regulatory and legal implications relating to the sophisticated cyber incident sustained by the Company in March 2021 that may arise.
 Impact of Natural and Man-Made Disasters and Mass Tort Claims
 • weather and other natural physical events, including the severity and frequency of storms, hail, snowfall and other winter conditions, natural disasters such as hurricanes, tornados and earthquakes, as well as climate change, including effects on global weather patterns, greenhouse gases, sea, land and air temperatures, sea levels, wildfires, rain, hail and snow;
 • regulatory requirements imposed by coastal state regulators in the wake of hurricanes or other natural disasters, including limitations on the ability to exit markets or to non-renew, cancel or change terms and

 conditions in policies, as well as mandatory assessments to fund any shortfalls arising from the inability of quasi-governmental insurers to pay claims;
 • man-made disasters, including the possible occurrence of terrorist attacks, the unpredictability of the nature, targets, severity or frequency of such events, and the effect of the absence or insufficiency of applicable terrorism legislation on coverages;
 • the occurrence of epidemics and pandemics; and
 • mass tort claims, including those related to exposure to potentially harmful products or substances such as glyphosate, lead paint, per- and polyfluoroalkyl substances (PFAS) and opioids; sexual abuse and molestation claims; and claims arising from changes that repeal or weaken tort reforms.
 Our forward-looking statements speak only as of the date of the filing of this Annual Report on Form 10-K and we do not undertake any obligation to update or revise any forward-looking statement to reflect events or circumstances after the date of the filing of this Annual Report on Form 10-K, even if our expectations or any related events or circumstances change.

 ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 Our financial instruments are exposed to various market risks, such as interest rate risk, equity price risk and foreign currency risk. Due to the level of risk associated with certain invested assets and the level of uncertainty related to changes in the value of these assets, it is possible that changes in these risks in the near term could have a material adverse impact on our results of operations, financial condition or equity.
 Discussions herein regarding market risk focus on only one element of market risk, which is price risk. Price risk relates to changes in the level of prices due to changes in interest rates, equity prices, foreign exchange rates or other factors such as credit spreads. The fair value of our financial instruments is generally adversely affected when interest rates rise, equity markets decline or the dollar strengthens against foreign currency.
 Active management of market risk is integral to our operations. We may take the following actions to manage our exposure to market risk within defined tolerance ranges: (1) change the character of future investments purchased or sold or (2) use derivatives to offset the market behavior of existing assets and liabilities or assets expected to be purchased and liabilities expected to be incurred.
 Sensitivity Analysis
 We monitor our sensitivity to interest rate changes by revaluing financial assets and liabilities using a variety of different interest rates. We use duration and convexity at the security level to estimate the change in fair value that would result from a change in each security's yield. Duration measures the price sensitivity of an asset to changes in yield. Convexity measures how the duration of the asset changes with interest rates. The duration and convexity analysis takes into account the unique characteristics (e.g., call and put options and prepayment expectations) of each security in determining the hypothetical change in fair value. The analysis is performed at the security level and aggregated up to the asset category levels for reporting in the tables below.
 The evaluation is performed by applying an instantaneous change in yield rates of varying magnitudes on a static balance sheet to determine the effect such a change in rates would have on our fair value at risk and the resulting effect on stockholders' equity. The analysis presents the sensitivity of the fair value of our financial instruments to selected changes in capital market rates and index levels. The range of change chosen reflects our view of changes that are reasonably possible over a one-year period. The selection of the range of values chosen to represent changes in interest rates should not be construed as our prediction of future market events, but rather an illustration of the impact of such events.
 The sensitivity analysis estimates the decline in the fair value of our interest sensitive assets and liabilities that were held as of December 31, 2023 and 2022 due to an instantaneous change in the yield of the security at the end of the period of 100 and 150 basis points, with all other variables held constant.
 The sensitivity analysis also assumes an instantaneous 10% and 20% decline in the foreign currency exchange rates versus the United States dollar from their levels as of December 31, 2023 and 2022, with all other variables held constant.
 Equity price risk was measured assuming an instantaneous 10% and 25% decline in the S&P 500 from its level as of December 31, 2023 and 2022, with all other variables held constant. Our common stock holdings, which are included in equity securities, were assumed to be highly and positively correlated with the S&P 500 index. For our limited partnership holdings, the estimated change in value was largely derived from a beta analysis calculation of historical experience of our portfolio and indices with similar strategies relative to the S&P 500.

 The following tables present the estimated effects on the fair value of our financial instruments as of December 31, 2023 and 2022 due to an increase in yield rates of 100 basis points, a 10% decline in foreign currency exchange rates and a 10% decline in the S&P 500, with all other variables held constant.

 Changes in discount rates used to measure our liability for future policyholder benefits (LFPB) would reduce the impact of the decrease in Fixed maturity securities within Other comprehensive income. The carrying value of the LFPB was $14.0 billion and $13.5 billion as of December 31, 2023 and 2022. The estimated decrease in the carrying value of the LFPB as of December 31, 2023 and 2022 due to an increase in yield rates of 100 basis points was $1.5 billion. The estimated decrease in the carrying value of the LFPB as of December 31, 2023 and 2022 due to an increase in yield rates of 150 basis points was $2.1 billion. We have estimated the change in the carrying value of the LFPB due to interest rate changes by discounting the expected future cash flows using different interest rate scenarios.

 (1) As of January 1, 2023, the Company adopted ASU 2018-12 using the modified retrospective method applied as of the transition date of January 1, 2021. Prior period amounts in the financial statements have been adjusted to reflect application of the new guidance. See Note A to the Consolidated Financial Statements for additional information.

 Notes to Consolidated Financial Statements

 Note A. Summary of Significant Accounting Policies
 Basis of Presentation
 The Consolidated Financial Statements include the accounts of CNA Financial Corporation (CNAF) and its subsidiaries. Collectively, CNAF and its subsidiaries are referred to as CNA or the Company. Loews Corporation (Loews) owned approximately 92 % of the outstanding common stock of CNAF as of December 31, 2023.
 The accompanying Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). Intercompany amounts have been eliminated. The preparation of Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates.
 Recently Adopted Accounting Standards Updates (ASU)
 ASU 2018-12: In August 2018, the Financial Accounting Standards Board (FASB) issued ASU 2018-12, Financial Services-Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts (ASU 2018-12; LDTI), which requires changes to the measurement and disclosure of long-duration contracts. Entities are required to review, and update if there is a change, cash flow assumptions (including morbidity and persistency) used to measure the liability for future policyholder benefits (LFPB) at least annually. The LFPB must also be updated for actual experience at least annually. The LFPB is reflected as Insurance reserves: Future policy benefits on the Consolidated Balance Sheet. The discount rate assumption used to measure the LFPB must be updated quarterly using an upper-medium grade (low credit risk) fixed-income instrument yield, commonly interpreted as a single-A rate. The effect of changes in cash flow assumptions and actual variances from expected experience are recorded in the Company's results of operations within Insurance claims and policyholders' benefits. The effect of changes in discount rate assumptions are recorded in Other comprehensive income (loss). In contrast, under legacy accounting guidance, cash flow and discount rate assumptions were locked-in unless a premium deficiency emerged. The discount rate assumption under legacy accounting guidance was determined using the Company's internal investment portfolio yield, which was generally higher than a single-A yield.
 The new guidance eliminates the need to hold shadow reserves associated with the Company's long-term care reserves. Under legacy accounting guidance, to the extent that unrealized gains on fixed maturity securities supporting long-term care reserves would have resulted in a premium deficiency if realized, a related increase to Insurance reserves was recorded, net of tax, as a reduction of net unrealized gains (losses), through Other comprehensive income (loss) (shadow reserves).
 The unit of account is the level at which reserves are measured. Under the new guidance, the unit of account used to measure the LFPB is the cohort. Cohorts are comprised of insurance contracts issued no more than one year apart, and must be further disaggregated according to policy benefit and insurance risk characteristics. Under legacy accounting guidance, the LFPB was generally measured at the individual policy level.
 Under the new guidance, the Net Premium Ratio (NPR) is capped at 100%. To the extent that NPR would otherwise exceed 100%, the LFPB is increased and a loss is recognized immediately in the Company's results of operations. The NPR cap is applied at the cohort level each quarter when the NPR is updated. In contrast, under legacy accounting guidance, premium deficiency testing was performed annually at the product level. See Note F to the Consolidated Financial Statements for further explanation of the NPR and LFPB calculations.
 The Company adopted the new guidance effective January 1, 2023, using the modified retrospective method applied as of the transition date of January 1, 2021. The Company's run-off long-term care business is in scope of the new guidance. All prior periods presented in the financial statements have been adjusted to reflect application of the new guidance. The Company's original locked in discount rate, utilized for purposes of

 calculating the NPR under the new guidance, was based on the discount rate assumption used to calculate the LFPB immediately prior to the transition date. While the requirements of the new guidance represent a material change from legacy accounting, the new guidance does not impact capital and surplus under statutory accounting practices, cash flows or the underlying economics of the business.
 In December 2022, the FASB issued ASU 2022-05, Financial Services-Insurance (Topic 944): Transition for Sold Contracts (ASU 2022-05). This guidance permits companies to make an election to exclude from the scope of ASU 2018-12 any insurance contracts that have been de-recognized prior to the effective date of ASU 2018-12, assuming that the company has no significant continuing involvement with the de-recognized contracts. In the fourth quarter of 2022, the Company novated its block of legacy annuity business, which was fully-ceded prior to novation. The Company has elected the ASU 2022-05 transition relief, and has excluded the novated legacy annuity business from the scope of ASU 2018-12.
 Explanation of ASU 2018-12 Transition Impacts:
 The following table presents a roll-forward of the pre-transition LFPB balance as of January 1, 2021:

 (1) In conjunction with the adoption of ASU 2018-12, at January 1, 2023, the Company reclassified the long-term care reserves for policyholders currently receiving benefits from Claim and claim adjustment expenses to Future policy benefits. This change was applied retrospectively as of January 1, 2021.
 Shadow reserves associated with the Company's long-term care business were de-recognized as of the transition date in Accumulated other comprehensive income (AOCI). The effect of re-measuring the LFPB at the single-A discount rate as of the transition date was similarly recorded in AOCI. The Company did not have any cohorts for which the NPR exceeded 100% at the transition date.
 The Company's practice under legacy accounting guidance was to calculate and record premium deficiency reserves at the policy level. Accordingly, an allocation methodology was not required to assign historical premium deficiency reserves to cohorts upon transition to ASU 2018-12.

 The following table presents after tax adjustments to the opening balance of Stockholders' equity resulting from adoption of ASU 2018-12:

 Accounting Standards Pending Adoption
 In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The updated accounting guidance requires expanded reportable segment disclosures, primarily related to significant segment expenses which are regularly provided to the company's Chief Operating Decision Maker. The guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within annual periods beginning after December 15, 2024. Retrospective application is required. The Company is currently evaluating the effect the updated guidance will have on the Company's financial statement disclosures.
 In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The updated accounting guidance requires expanded income tax disclosures, including the disaggregation of existing disclosures related to the tax rate reconciliation and income taxes paid. The guidance is effective for annual periods beginning after December 15, 2024. Prospective application is required, with retrospective application permitted. The Company is currently evaluating the effect the updated guidance will have on the Company's financial statement disclosures.
 Insurance Operations
 Premiums: Insurance premiums on property and casualty insurance contracts are recognized in proportion to the underlying risk insured and are primarily earned ratably over the term of the policies. Premiums on long-term care contracts are earned ratably over the policy year in which they are due. The reserve for unearned premiums represents the portion of premiums written relating to the unexpired terms of coverage.
 Property and casualty contracts that are retrospectively rated or subject to audit premiums contain provisions that result in an adjustment to the initial policy premium depending on the contract provisions. These provisions stipulate the adjustment due to loss experience of the insured during the coverage period, or changes in the level of exposure to insurance risk. For such contracts, the Company estimates the amount of ultimate premiums that the Company may earn upon completion of the coverage period and recognizes either an asset or a liability for the difference between the initial policy premium and the estimated ultimate premium. The Company either adjusts such estimated ultimate premium amounts during the course of the coverage period based on actual results to date, or by conducting premium audits after the policy has expired to determine the final exposure to insured risks. The resulting adjustment is recorded as either a reduction of or an increase to the earned premiums for the period.

 Insurance receivables include balances due currently or in the future, including amounts due from insureds related to paid losses under high deductible policies, and are presented at unpaid balances, net of an allowance for uncollectible receivables. A loss rate methodology is used to determine expected credit losses for premium receivables. This methodology uses the Company's historical annual credit losses relative to gross premium written to develop a range of credit loss rates for each dollar of gross written premium underwritten. Additionally, an expected credit loss for amounts due from insureds under high deductible and retrospectively rated policies is calculated on a pool basis, informed by historical default rate data obtained from major rating agencies. Changes in the allowance are presented as a component of Other operating expenses on the Consolidated Statements of Operations. Amounts are considered past due based on policy payment terms. Insurance receivables and any related allowance are written off after collection efforts are exhausted or a negotiated settlement is reached. See the Credit Losses section of this note for additional information on the Company's allowances for expected credit losses.
 Claim and claim adjustment expense reserves: Claim and claim adjustment expense reserves, except reserves for structured settlements not associated with asbestos and environmental pollution (A&EP) and workers' compensation lifetime claims, are not discounted and are based on i) case basis estimates for losses reported on direct business, adjusted in the aggregate for ultimate loss expectations; ii) estimates of incurred but not reported (IBNR) losses; iii) estimates of losses on assumed reinsurance; iv) estimates of future expenses to be incurred in the settlement of claims; v) estimates of salvage and subrogation recoveries and vi) estimates of amounts due from insureds related to losses under high deductible policies. Management considers current conditions and trends as well as past Company and industry experience in establishing these estimates. The effects of inflation, which can be significant, are implicitly considered in the reserving process and are part of the recorded reserve balance. Ceded claim and claim adjustment expense reserves are reported as a component of Reinsurance receivables on the Consolidated Balance Sheets.
 Claim and claim adjustment expense reserves are presented net of anticipated amounts due from insureds related to losses under deductible policies of $ 1.2 billion and $ 1.1 billion as of December 31, 2023 and 2022. A significant portion of these amounts are supported by collateral. The Company has an allowance for uncollectible deductible amounts, which is presented as a component of the allowance for doubtful accounts included in Insurance receivables on the Consolidated Balance Sheets.
 Structured settlements have been negotiated for certain property and casualty insurance claims. Structured settlements are agreements to provide fixed periodic payments to claimants. The Company's obligations for structured settlements not funded by annuities are included in claim and claim adjustment expense reserves and are discounted at a weighted average interest rate of 6.4 % as of December 31, 2023 and 2022. This interest rate is based on the expected yield of the assets that support the reserves and reinvestment assumptions. As of December 31, 2023 and 2022, the discounted reserves for unfunded structured settlements were $ 465 million and $ 485 million, net of discount of $ 559 million and $ 590 million. For the years ended December 31, 2023, 2022 and 2021, the amount of interest recognized on the discounted reserves of unfunded structured settlements was $ 34 million, $ 36 million and $ 36 million, respectively. This interest accretion is presented as a component of Insurance claims and policyholders' benefits on the Consolidated Statements of Operations, but is excluded from the Company's disclosure of prior year loss reserve development.
 Workers' compensation lifetime claim reserves are calculated using mortality assumptions determined through statutory regulation and economic factors. As of December 31, 2023 and 2022, workers' compensation lifetime claim reserves are discounted at a 3.5 % interest rate. As of December 31, 2023 and 2022, the discounted reserves for workers' compensation lifetime claim reserves were $ 196 million and $ 211 million, net of discount of $ 88 million and $ 93 million. For the years ended December 31, 2023, 2022 and 2021, the amount of interest accretion recognized on the discounted reserves of workers' compensation lifetime claim reserves was $ 9 million, $ 9 million and $ 12 million, respectively. This interest accretion is presented as a component of Insurance claims and policyholders' benefits on the Consolidated Statements of Operations, but is excluded from the Company's disclosure of prior year loss reserve development.
 Future policy benefit reserves: Future policy benefit reserves are associated with the Company's run-off long-term care business and relate to policyholders that are currently receiving benefits, including claims that have been incurred but are not yet reported, as well as policyholders that are not yet receiving benefits.

 The LFPB is computed using the net level premium method, which incorporates cash flow assumptions and discount rate assumptions. Under the net level premium method, the LFPB is equal to the present value of future benefits and claim settlement expenses less the present value of future net premiums. Net premiums are equal to gross premiums multiplied by the NPR. The NPR is generally the ratio of the present value of benefits and expense payments to the present value of gross premiums, expected over the lifetime of the policy. As a result of the modified retrospective adoption of ASU 2018-12, the Company's NPR calculation incorporates the original locked in discount rate and the reserve balance as of the transition date of January 1, 2021.
 The key cash flow assumptions used to estimate the LFPB are morbidity, persistency (inclusive of mortality), anticipated future premium rate increases and expenses. Morbidity is the frequency and severity of injury, illness, sickness and diseases contracted. Persistency is the percentage of policies remaining in force and can be affected by policy lapses, benefit reductions and death. Future premium rate increases are generally subject to regulatory approval, and therefore the exact timing and size of the approved rate increases are unknown. Expense assumptions relate to claim adjudication. The Company has not elected the practical expedient that allows locking in the expense assumption. The carried LFPB discount rate is determined using the upper-medium grade fixed income instrument yield curve.
 The Company has elected to update the NPR and the LFPB for actual experience on a quarterly basis. A quarterly assessment is also made as to whether evidence suggests that cash flow assumptions should be updated. Annually, in the third quarter, actuarial analysis is performed on policyholder morbidity, persistency, premium rate increases and expense experience. This analysis, combined with judgment, informs the setting of updated cash flow assumptions used to estimate the LFPB. Actuarial analysis includes predictive modeling, actual to expected experience comparisons and trend analysis. Applicable industry research is also considered.
 Quarterly, to derive the upper-medium grade fixed income instrument yield discount rate assumption, the Company uses a published spot rate curve constructed from single-A rated U.S. dollar denominated corporate bonds. The Company uses linear interpolation to determine yield assumptions for tenors that fall between points for which observable rates are available. For cash flows that are projected to occur beyond the tenor for which market-observable rates are available, the Company applies judgment to estimate a normative rate which the Company grades to over 10 years.
 Quarterly, the updated NPR is used to derive an updated LFPB as of the beginning of the current quarter measured at the original locked in discount rate. The updated LFPB is then compared to the existing carrying amount of the liability as of the same date (measured at the original locked in discount rate) to determine the re-measurement gain (loss), which is presented parenthetically within the Insurance claims and policyholders' benefits line on the Consolidated Statements of Operations.
 Insurance contracts are grouped into cohorts according to issue year. Contracts assumed through reinsurance are generally included within the same cohorts as contracts issued directly by the Company, according to issue year. The issue year for assumed contracts is defined according to the date that the Company's assumption of insurance risk incepted. For assumed contracts that were reinsured concurrently with the issuance of the underlying direct contract, issue year is defined as the year that the underlying policy was issued. For contracts that were already in-force when assumed by the Company, issue year is defined as the year in which the reinsurance agreement incepted. For group long-term care business, issue year is defined as the year the individual insurance certificate was issued. Long-term care is the Company's only long-duration product line, therefore, cohorts are not further disaggregated by product.
 Insurance-related assessments: Liabilities for insurance-related assessments are accrued when an assessment is probable, when it can be reasonably estimated and when the event obligating the entity to pay an imposed or probable assessment has occurred. Liabilities for insurance-related assessments are not discounted and are included as part of Other liabilities on the Consolidated Balance Sheets. As of December 31, 2023 and 2022, the liability balances were $ 84 million and $ 74 million.
 Reinsurance: Reinsurance accounting allows for contractual cash flows to be reflected as premiums and losses. To qualify for reinsurance accounting, reinsurance agreements must include risk transfer. To meet risk transfer requirements, a reinsurance contract must include both insurance risk, consisting of underwriting and timing risk, and a reasonable possibility of a significant loss for the assuming entity.

 Reinsurance receivables related to paid losses are presented at unpaid balances. Reinsurance receivables related to unpaid losses are estimated in a manner consistent with claim and claim adjustment expense reserves or future policy benefit reserves. Reinsurance receivables are reported net of an allowance for uncollectible amounts on the Consolidated Balance Sheets. The cost of reinsurance is primarily accounted for over the life of the underlying reinsured policies using assumptions consistent with those used to account for the underlying policies or over the reinsurance contract period. The ceding of insurance does not discharge the primary liability of the Company.
 The Company has established an allowance for uncollectible reinsurance receivables which relates to both amounts already billed on ceded paid losses as well as ceded reserves that will be billed when losses are paid in the future. For assessing expected credit losses, the Company separates reinsurance receivables into two pools: voluntary reinsurance receivables and involuntary receivables related to mandatory pools. The Company has not recorded an allowance for involuntary pools as there is no perceived credit risk. The principal credit quality indicator used in the valuation of the allowance on voluntary reinsurance receivables is the financial strength rating of the reinsurer sourced from major rating agencies. If the reinsurer is unrated, an internal financial strength rating is assigned based on the Company's historical loss experience and the Company's assessment of the reinsurance counterparty's risk profile, which generally corresponds with a B rating. Reinsurer financial strength ratings are updated and reviewed on an annual basis or sooner if the Company becomes aware of significant changes related to a reinsurer. The allowance for uncollectible reinsurance receivables is estimated on the basis of periodic evaluations of balances due from reinsurers, reinsurer financial strength rating and solvency, industry experience and current and forecast economic conditions. Because billed receivables generally approximate 5 % or less of total reinsurance receivables, the age of the reinsurance receivables related to paid losses is not a significant input into the allowance analysis. Changes in the allowance for uncollectible reinsurance receivables are presented as a component of Insurance claims and policyholders' benefits on the Consolidated Statements of Operations. See the Credit Losses section of this note for additional information on the Company's allowances for expected credit losses.
 Amounts are considered past due based on the reinsurance contract terms. Reinsurance receivables related to paid losses and any related allowance are written off after collection efforts have been exhausted or a negotiated settlement is reached with the reinsurer. Reinsurance receivables from insolvent insurers related to paid losses are written off when the settlement due from the estate can be reasonably estimated. At the time reinsurance receivables related to paid losses are written off, any required adjustment to reinsurance receivables related to unpaid losses is recorded as a component of Insurance claims and policyholders' benefits on the Consolidated Statements of Operations.
 A loss portfolio transfer is a retroactive reinsurance contract. If the cumulative claim and allocated claim adjustment expenses ceded under a loss portfolio transfer exceed the consideration paid, the resulting gain from such excess is deferred and amortized into earnings in future periods in proportion to actual recoveries under the loss portfolio transfer. In any period in which there is a revised estimate of claim and allocated claim adjustment expenses and the loss portfolio transfer is in a gain position, the deferred gain is recalculated as if the revised estimate was available at the inception date of the loss portfolio transfer and the change in the deferred gain is recognized in earnings.
 Deferred acquisition costs: Deferrable acquisition costs include commissions, premium taxes and certain underwriting and policy issuance costs which are incremental direct costs of successful contract acquisitions. Acquisition costs related to property and casualty business are deferred and amortized ratably over the period the related premiums are earned. Deferred acquisition costs are presented net of ceding commissions and other ceded acquisition costs.
 The Company evaluates deferred acquisition costs for recoverability. Anticipated investment income is considered in the determination of the recoverability of deferred acquisition costs. Adjustments, if necessary, are recorded in current period results of operations.

 Policyholder dividends: Policyholder dividends are paid to participating policyholders within the workers' compensation and surety lines of business. Net written premiums for participating dividend policies were approximately 2 %, 2 % and 1 % of total net written premiums for each of the years ended December 31, 2023, 2022 and 2021. Dividends to policyholders are accrued according to the Company's best estimate of the amount to be paid in accordance with contractual provisions and applicable state laws. Dividends to policyholders are presented as a component of Insurance claims & policyholders' benefits on the Consolidated Statements of Operations and Other liabilities on the Consolidated Balance Sheets.
 Investments
 The Company classifies its fixed maturity securities as either available-for-sale or trading, and as such, they are carried at fair value. Changes in fair value of trading securities are reported within Net investment income on the Consolidated Statements of Operations. Changes in fair value of available-for-sale securities are reported as a component of Other comprehensive income.
 The cost of fixed maturity securities classified as available-for-sale is adjusted for amortization of premiums and accretion of discounts, which are included in Net investment income on the Consolidated Statements of Operations. The amortization of premium and accretion of discount for fixed maturity securities takes into consideration call and maturity dates that produce the lowest yield.
 For asset-backed securities included in fixed maturity securities, the Company recognizes income using an effective yield based on anticipated prepayments and the estimated economic life of the securities. When estimates of prepayments change, the effective yield is recalculated to reflect actual payments to date and anticipated future payments predominantly using the retrospective method.
 Equity securities are carried at fair value. The Company's non-redeemable preferred stock contain characteristics of debt securities, are priced similarly to bonds and are held primarily for income generation through periodic dividends. While recognition of gains and losses on these securities is not discretionary, management does not consider the changes in fair value of non-redeemable preferred stock to be reflective of our primary operations. As such, the changes in the fair value of these securities are recorded through Net investment gains (losses) on the Consolidated Statements of Operations. The Company owns certain common stock with the intention of holding the securities primarily for market appreciation and as such, the changes in the fair value of these securities are recorded through Net investment income.
 The Company's carrying value of investments in limited partnerships is its share of the net asset value of each partnership, as determined by the general partner. Certain partnerships for which results are not available on a timely basis are reported on a lag, primarily three months or less. Changes in net asset values are accounted for under the equity method and recorded within Net investment income on the Consolidated Statements of Operations.
 Mortgage loans are commercial in nature, are carried at unpaid principal balance, net of unamortized fees and an allowance for expected credit losses, and are recorded once funded. The allowance for expected credit losses is developed by assessing the credit quality of pools of mortgage loans in good standing using debt service coverage ratios (DSCR) and loan-to-value ratios (LTV). The DSCR compares a property's net operating income to its debt service payments, including principal and interest. The LTV ratio compares the current unpaid principal balance of the loan to the estimated fair value of the underlying property collateralizing the loan. The pools developed to measure the credit loss allowance use increments of DSCR and LTV to draw distinctions between risk levels. The Company applies expected credit loss rates by pool to the outstanding receivable balances. Changes in the allowance for mortgage loans are presented as a component of Net investment gains (losses) on the Consolidated Statements of Operations. See the Credit Losses section of this note for additional information on the Company's allowances for expected credit losses. Interest income from mortgage loans is recognized on an accrual basis using the effective yield method.
 Other invested assets include overseas deposits. Overseas deposits are valued using the net asset value per share (or equivalent) practical expedient. They are primarily short-term government securities, agency securities and corporate bonds held in trusts that are managed by Lloyd's of London. These funds are required of Lloyd's syndicates to protect policyholders in overseas markets and may be denominated in local currency.

 Short-term investments are carried at fair value, with the exception of cash accounts earning interest, which are carried at cost and approximate fair value. Changes in fair value are reported as a component of Other comprehensive income.
 Purchases and sales of all securities are recorded on the trade date, except for private placement securities, including bank loan participations, which are recorded once funded. Net investment gains and losses are determined on the basis of the cost or amortized cost of the specific securities sold.
 In the normal course of investing activities, the Company enters into relationships with variable interest entities (VIEs), as both an investor in limited partnerships and asset-backed securities issued by third-party VIEs. The Company is not the primary beneficiary of these VIEs, and therefore does not consolidate them. The Company determines whether it is the primary beneficiary of a VIE based on a qualitative assessment of the relative power and benefits of the Company and the other participants in the VIE. The Company's maximum exposure to loss with respect to these investments is limited to the investment carrying values included in the Company's Consolidated Balance Sheets and any unfunded commitments.
 An available-for-sale security is impaired if the fair value of the security is less than its cost adjusted for accretion, amortization and allowance for credit losses. When a security is impaired, it is evaluated to determine whether the Company intends to sell the security before recovery of amortized cost or whether a credit loss exists. Losses on securities that the Company intends to sell are recognized as impairment losses within Net investment gains (losses) on the Consolidated Statements of Operations. If a credit loss exists, an allowance is established and the corresponding amount is recognized as an impairment loss within Net investment gains (losses) on the Consolidated Statements of Operations. The allowance for credit losses related to available-for-sale fixed maturity securities is the difference between the present value of cash flows expected to be collected and the amortized cost basis, limited by the amount that the fair value is less than the amortized cost basis. In subsequent periods, the allowance is reviewed, with any changes in the allowance presented as a component of Net investment gains (losses) on the Consolidated Statements of Operations. Changes in the difference between the amortized cost basis, net of the allowance, and the fair value, are recognized in Other comprehensive income.
 Significant judgment is required in the determination of whether an impairment loss has occurred for a security. The Company follows a consistent and systematic process for determining and recording an impairment loss, including the evaluation of securities in an unrealized loss position and securities with an allowance for credit losses on at least a quarterly basis.
 The Company's assessment of whether an impairment loss has occurred incorporates both quantitative and qualitative information. A credit loss exists if the present value of cash flows expected to be collected is less than the amortized cost basis. Significant assumptions enter into these cash flow projections including delinquency rates, probable risk of default, loss severity upon a default, over collateralization and interest coverage triggers and credit support from lower level tranches. The Company considers all available evidence when determining whether an investment requires a credit loss write-down or allowance to be recorded. Examples of such evidence may include the financial condition and near-term and long-term prospects of the issuer, whether the issuer is current with interest and principal payments, credit ratings on the security or changes in ratings over time, general market conditions and industry, sector or other specific factors and whether it is likely that the Company will recover its amortized cost through the collection of cash flows. See the Credit Losses section of this note for additional information on the Company's allowances for expected credit losses.
 Credit Losses
 The allowances for credit losses on fixed maturity securities, mortgage loans, reinsurance receivables and insurance receivables are valuation accounts that are reported as a reduction of a financial asset's cost basis and are measured on a pool basis when similar risk characteristics exist. Management estimates the allowance using relevant available information from both internal and external sources. Historical credit loss experience provides the basis for the estimation of expected credit losses and adjustments may be made to reflect current conditions and reasonable and supportable forecasts. Adjustments to historical loss information are made for any additional factors that come to the Company's attention. This could include significant shifts in

 counterparty financial strength ratings, aging of past due receivables, amounts sent to collection agencies, or other underlying portfolio changes. Amounts are considered past due when payments have not been received according to contractual terms. The Company also considers current and forecast economic conditions, using a variety of economic metrics and forecast indices. The sensitivity of expected credit losses relative to changes to these forecast economic conditions can vary by financial asset class. The Company considers a reasonable and supportable forecast period to be up to 24 months from the balance sheet date. After the forecast period, the Company reverts to historical credit experience. The Company uses collateral arrangements such as letters of credit and amounts held in beneficiary trusts to mitigate credit risk, which are considered in the estimate of net amount expected to be collected. Amounts are written off against the allowance when determined to be uncollectible.
 The Company has made a policy election to present accrued interest balances separately from the amortized cost basis of assets and has elected the practical expedient to exclude the accrued interest from the tabular disclosures for mortgage loans and available-for-sale securities. The Company has elected not to estimate an allowance for credit losses on accrued interest receivable. The accrual of interest income is discontinued and the asset is placed on nonaccrual status within 90 days of the interest becoming delinquent. Interest accrued but not received for assets on nonaccrual status is reversed through investment income. Interest received for assets that are on nonaccrual status is recognized as payment is received. The asset is returned to accrual status when the principal and interest amounts contractually due are brought current and future payments are expected. Interest receivable is presented as a component of accrued investment income on the Consolidated Balance Sheet.
 Deferred Non-Insurance Warranty Revenue and Acquisition Expense
 Non-insurance warranty revenue is primarily generated from separately-priced service contracts that provide mechanical breakdown and other coverages to vehicle or consumer goods owners. The warranty contracts generally provide coverage from 1 month to 10 years. For warranty products where the Company acts as the principal in the transaction, Non-insurance warranty revenue is reported on a gross basis, with amounts paid by customers reported as Non-insurance warranty revenue and commissions paid to agents and dealers reported as Non-insurance warranty expense.
 Non-insurance warranty revenue is reported net of any premiums related to contractual liability coverage issued by the Company's insurance operations. Additionally, the Company provides warranty administration services for dealer and manufacturer obligor warranty products, which include limited warranties and guaranteed asset protection waivers. The Company recognizes Non-insurance warranty revenue over the service period in proportion to the actuarially determined expected claims emergence pattern. Customers predominantly pay in full at the inception of the warranty contract. The liability for deferred revenue represents the unearned portion of revenue in advance of the Company's performance. The deferred revenue balance includes amounts which are refundable on a pro rata basis upon cancellation.
 Dealers, retailers and agents earn commission for assisting the Company in obtaining non-insurance warranty contracts. Additionally, the Company utilizes third-parties to perform warranty administrator services for its consumer goods warranties. These costs, which are deferred and recorded as Deferred non-insurance warranty acquisition expense, are amortized to Non-insurance warranty expense consistent with how the related revenue is recognized. The Company evaluates deferred costs for recoverability including consideration of anticipated investment income. Adjustments to deferred costs, if necessary, are recorded in the current period results of operations.
 Income Taxes
 The Company and its eligible subsidiaries (CNA Tax Group) are included in the consolidated federal income tax return of Loews and its eligible subsidiaries. The Company accounts for income taxes under the asset and liability method. Under the asset and liability method, deferred income taxes are recognized for temporary differences between the financial statement and tax return bases of assets and liabilities, based on enacted tax rates and other provisions of the tax law. The effect of a change in tax laws or rates on deferred tax assets and liabilities is recognized in income in the period in which such change is enacted. Future tax benefits are recognized to the extent that realization of such benefits is more likely than not, and a valuation allowance is

 established for any portion of a deferred tax asset that management believes will not be realized. The Company releases tax effects from AOCI utilizing the security-by-security approach for Net unrealized gains (losses) on investments with an allowance for credit losses and Net unrealized gains (losses) on other investments. For Pension and postretirement benefits, tax effects from AOCI are released at enacted tax rates based on the pre-tax adjustments to pension liabilities or assets recognized within Other comprehensive income.
 Pension and Postretirement Benefits
 The Company recognizes the overfunded or underfunded status of its defined benefit plans in Other assets or Other liabilities on the Consolidated Balance Sheets. Changes in funded status related to prior service costs and credits, and actuarial gains and losses arising from differences between actual experience and actuarial assumptions, are recognized in the year in which the changes occur through Other comprehensive income. Unrecognized actuarial gains and losses in excess of 10% of the greater of the beginning of the year projected benefit obligation or fair value of plan assets (the corridor) are amortized as a component of net periodic pension cost (benefit) over the average remaining life expectancy of the plan participants. Annual service cost, interest cost, expected return on plan assets, amortization of prior service costs and credits and amortization of actuarial gains and losses are recognized on the Consolidated Statements of Operations.
 The vested benefit obligation for the CNA Retirement Plan is determined based on eligible compensation and accrued service for previously entitled employees. Effective June 30, 2015, future benefit accruals under the CNA Retirement Plan were eliminated and the benefit obligations were frozen.
 Stock-Based Compensation
 The Company records compensation expense using the fair value method for all awards it grants, modifies or cancels primarily on a straight-line basis over the requisite service period, generally three years.
 Foreign Currency
 The Company's foreign subsidiaries' balance sheet accounts are translated at the exchange rates in effect at each reporting date and income statement accounts are either translated at the exchange rates on the date of the transaction or at average exchange rates. Foreign currency translation gains and losses are reflected in Stockholders' equity as a component of AOCI. Foreign currency transaction gains (losses) of $ 9 million, $( 22) million and less than $( 1) million were included in determining Net income for the years ended December 31, 2023, 2022 and 2021, respectively.
 Leases
 A lease provides the lessee the right to control the use of an identified asset for a period of time in exchange for consideration. Operating lease right-of-use (ROU) assets and lease liabilities are included in Other assets and Other liabilities on the Company's Consolidated Balance Sheets.
 ROU assets represent the Company's right to use an underlying asset for the lease term and operating lease liabilities represent the Company's obligation to make lease payments arising from the lease. The Company determines if an arrangement is a lease at inception. Operating lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Most operating leases contain renewal options that provide for rent increases based on prevailing market conditions. Certain leases contain options to terminate before maturity. The lease term used to calculate the ROU asset includes any renewal options or lease termination options that the Company expects to exercise. The discount rate used to determine the commencement date present value of lease payments is typically the Company's secured borrowing rate, as most of the Company's leases do not provide an implicit rate. ROU assets include any lease payments required to be made prior to commencement and exclude lease incentives. The Company has elected to account for its lease and non-lease components as a single lease component. The Company's non-lease components consist of variable lease costs not based on an index or rate and are excluded from the measurement of ROU assets and lease liabilities. Variable lease costs not based on an index or rate are treated as period costs, and represent charges for services provided by the landlord and the Company's reimbursement to the landlord for costs such as real estate taxes and insurance.

 The Company occupies office facilities under lease agreements that expire at various dates. The Company's lease agreements do not contain significant residual value guarantees, restrictions or covenants. The Company does not have any significant finance leases.
 Property and Equipment
 Property and equipment are carried at cost less accumulated depreciation. Depreciation is based on the estimated useful lives of the various classes of property and equipment and is determined principally on the straight-line method. Furniture and fixtures are depreciated over seven years. Office equipment is depreciated over five years. The estimated lives for data processing equipment and software generally range from three to five years, but can be as long as ten years. Leasehold improvements are depreciated over the corresponding lease terms not to exceed the underlying asset life.
 Goodwill represents the excess of purchase price over the fair value of the net assets of acquired entities and businesses. Goodwill in the International segment may change from period to period as a result of foreign currency translation.
 Goodwill is tested for impairment annually or when certain triggering events require such tests. As a result of reviews completed for the year ended December 31, 2023, the Company determined that the estimated fair value of the reporting units were in excess of their carrying value including Goodwill. Changes in future periods in assumptions about the level of economic capital, business growth, earnings projections or the weighted average cost of capital could result in goodwill impairment.
 Other Intangible Assets
 Other intangible assets are reported within Other assets on the Consolidated Balance Sheets. Finite-lived intangible assets are amortized over their estimated useful lives. Indefinite-lived other intangible assets are tested for impairment annually or when certain triggering events require such tests.
 Earnings (Loss) Per Share Data
 Earnings (loss) per share is based on weighted average number of outstanding common shares. Basic earnings (loss) per share excludes the impact of dilutive securities and is computed by dividing Net income (loss) by the weighted average number of common shares outstanding for the period. Diluted earnings (loss) per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.
 For each of the years ended December 31, 2023, 2022 and 2021, approximately 1 million potential shares attributable to exercises or conversions into common stock under stock-based employee compensation plans were included in the calculation of diluted earnings per share. Excluded from the calculation of diluted earnings (loss) per share is the impact of potential shares attributable to exercises or conversions into common stock under stock-based employee compensation plans that would have been antidilutive during the respective periods.
 Supplementary Cash Flow Information
 Cash payments made for interest were $ 124 million, $ 109 million and $ 110 million for the years ended December 31, 2023, 2022 and 2021. Cash payments made for income taxes were $ 282 million, $ 277 million and $ 278 million for the years ended December 31, 2023, 2022 and 2021.

 Net investment gains (losses) for the year ended December 31, 2022 in the table above included an $ 18 million net gain related to the novation of a coinsurance agreement on the Company's legacy annuity business, which was transacted on a funds withheld basis and gave rise to an embedded derivative. The net gain of $ 18 million was comprised of a $ 62 million gain on the associated embedded derivative partially offset by a $ 44 million loss on fixed maturity securities supporting the funds withheld liability, transferred with the novation, to recognize unrealized losses which had been included in AOCI since the inception of the coinsurance agreement. Taken together, this net gain was the final recognition of changes in the valuation of the funds held assets and offset previously recognized net investment losses on the associated embedded derivative. The coinsurance agreement was novated in the fourth quarter of 2022.

 Based on current facts and circumstances, the Company believes the unrealized losses presented in the December 31, 2023 securities in a gross unrealized loss position tables above are not indicative of the ultimate collectability of the current amortized cost of the securities, but rather are primarily attributable to changes in risk-free interest rates. In reaching this determination, the Company considered the volatility in risk-free rates and credit spreads as well as the fact that its unrealized losses are concentrated in investment grade issuers. Additionally, the Company has no current intent to sell securities with unrealized losses, nor is it more likely than not that it will be required to sell prior to recovery of amortized cost; accordingly, the Company has determined that there are no additional impairment losses to be recorded as of December 31, 2023.

 The following tables present the activity related to the allowance on available-for-sale securities with credit impairments and purchased credit-deteriorated (PCD) assets. Accrued interest receivable on available-for-sale fixed maturity securities totaled $ 435 million and $ 394 million as of December 31, 2023 and 2022 and is excluded from the estimate of expected credit losses and the amortized cost basis in the table included within this Note.

 Actual maturities may differ from contractual maturities because certain securities may be called or prepaid. Securities not due at a single date are allocated based on weighted average life.
 Limited Partnerships
 The carrying value of limited partnerships as of December 31, 2023 and 2022 was $ 2,174 million and $ 1,926 million, which includes net undistributed earnings of $ 250 million and $ 176 million. Limited partnerships comprising 17 % of the total carrying value are reported on a current basis through December 31, 2023 with no reporting lag, 4 % are reported on a one month lag and the remainder are reported on more than a one month lag. The number of limited partnerships held and the strategies employed provide diversification to the limited partnership portfolio and the overall invested asset portfolio.
 Limited partnerships comprising 85 % and 76 % of the carrying value as of December 31, 2023 and 2022 were invested in private debt and equity. Limited partnerships comprising 15 % and 24 % of the carrying value as of December 31, 2023 and 2022 employ hedge fund strategies. Private debt and equity funds cover a broad range of investment strategies including buyout, co-investment, private credit, growth capital, distressed investing and real estate. Hedge fund strategies include both long and short positions in fixed income, equity and derivative instruments.
 The ten largest limited partnership positions held totaled $ 622 million and $ 633 million as of December 31, 2023 and 2022. Based on the most recent information available regarding the Company's percentage ownership of the individual limited partnerships, the carrying value reflected on the Consolidated Balance Sheets represents approximately 1 % of the aggregate partnership equity as of December 31, 2023 and 2022, and the related income reflected on the Consolidated Statements of Operations represents approximately 1 %, 2 % and 2 % of the changes in aggregate partnership equity for the years ended December 31, 2023, 2022 and 2021.
 There are risks inherent in limited partnership investments which may result in losses due to short-selling, derivatives or other speculative investment practices. The use of leverage increases volatility generated by the underlying investment strategies.
 The Company's private debt, private equity and other non-hedge fund limited partnership investments generally do not permit voluntary withdrawals. The Company's hedge fund limited partnership investments contain withdrawal provisions that generally limit liquidity for a period of thirty days up to one year or longer. Typically, hedge fund withdrawals require advance written notice of up to 90 days.

 Derivative Financial Instruments
 The Company may use derivatives in the normal course of business, primarily in an attempt to reduce its exposure to market risk (principally interest rate risk and foreign currency risk) stemming from various assets and liabilities. The Company's principal objective under such strategies is to achieve the desired reduction in economic risk, even if the position does not receive hedge accounting treatment.
 The Company may enter into interest rate swaps, futures and forward commitments to purchase securities to manage interest rate risk. The Company may use foreign currency forward contracts to manage foreign currency risk.
 Credit exposure associated with non-performance by the counterparties to derivative instruments is generally limited to the uncollateralized fair value of the asset related to the instruments recognized on the Consolidated Balance Sheets. The Company generally requires that all over-the-counter derivative contracts be governed by an International Swaps and Derivatives Association Master Agreement, and exchanges collateral under the terms of these agreements with its derivative investment counterparties depending on the amount of the exposure and the credit rating of the counterparty. Gross estimated fair values of derivative positions are presented in Other invested assets and Other liabilities on the Consolidated Balance Sheets. The Company does not offset derivative positions against the fair value of collateral provided or positions subject to netting arrangements. There would be no significant difference in the balance included in such accounts if the estimated fair values were presented net as of December 31, 2023 and 2022.
 There was less than $ 1 million of cash collateral provided by the Company and no cash collateral received from counterparties as of December 31, 2023 and 2022.
 During the year ended December 31, 2022, the Company held an embedded derivative on a funds withheld liability related to a coinsurance agreement on its legacy annuity business. The Company novated the coinsurance agreement during 2022 resulting in the transfer of $ 224 million of fixed maturity securities, $ 4 million of short-term investments and $ 2 million of accrued investment income in settlement of the $ 216 million funds withheld liability and associated $ 14 million embedded derivative.
 Investment Commitments
 As part of its overall investment strategy, the Company invests in various assets which require future purchase, sale or funding commitments. These investments are recorded once funded, and the related commitments may include future capital calls from various third-party limited partnerships, signed and accepted mortgage loan applications, and obligations related to private placement securities. As of December 31, 2023, the Company had commitments to purchase or fund approximately $ 1,555 million and sell approximately $ 35 million under the terms of these investments.
 Investments on Deposit
 Cash and securities with carrying values of approximately $ 3.1 billion and $ 2.8 billion were deposited by the Company's insurance subsidiaries under requirements of regulatory authorities and others as of December 31, 2023 and 2022.
 Cash and securities with carrying values of approximately $ 0.9 billion were deposited with financial institutions in trust accounts or as collateral for letters of credit to secure obligations with various third parties as of December 31, 2023 and 2022.

 Mortgage Loans
 The following table presents the amortized cost basis of mortgage loans for each credit quality indicator by year of origination. The primary credit quality indicators utilized are debt service coverage ratios (DSCR) and loan-to-value ratios (LTV).

 As of December 31, 2023, accrued interest receivable on mortgage loans totaled $ 4 million and is excluded from the amortized cost basis disclosed in the table above and the estimate of expected credit losses.

 Note C. Fair Value

 Fair value is the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The following fair value hierarchy is used in selecting inputs, with the highest priority given to Level 1, as these are the most transparent or reliable.
 Level 1 - Quoted prices for identical instruments in active markets.
 Level 2 - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets.
 Level 3 - Valuations derived from valuation techniques in which one or more significant inputs are not observable.
 Prices may fall within Level 1, 2 or 3 depending upon the methodology and inputs used to estimate fair value for each specific security. In general, the Company seeks to price securities using third-party pricing services. Securities not priced by pricing services are submitted to independent brokers for valuation and, if those are not available, internally developed pricing models are used to value assets using a methodology and inputs the Company believes market participants would use to value the assets. Prices obtained from third-party pricing services or brokers are not adjusted by the Company.
 The Company performs control procedures over information obtained from pricing services and brokers to ensure prices received represent a reasonable estimate of fair value and to confirm representations regarding whether inputs are observable or unobservable. Procedures may include i) the review of pricing service methodologies or broker pricing qualifications, ii) back-testing, where past fair value estimates are compared to actual transactions executed in the market on similar dates, iii) exception reporting, where period-over-period changes in price are reviewed and challenged with the pricing service or broker based on exception criteria, and iv) deep dives, where the Company performs an independent analysis of the inputs and assumptions used to price individual securities.

 Assets and Liabilities Measured at Fair Value

 Securities may be transferred in or out of levels within the fair value hierarchy based on the availability of observable market information and quoted prices used to determine the fair value of the security. The availability of observable market information and quoted prices varies based on market conditions and trading volume.

 Valuation Methodologies and Inputs
 The following section describes the valuation methodologies and relevant inputs used to measure different financial instruments at fair value, including an indication of the level in the fair value hierarchy in which the instruments are generally classified.
 Fixed Maturity Securities
 Level 1 securities include highly liquid government securities and exchange traded bonds, valued using quoted market prices. Level 2 securities include most other fixed maturity securities as the significant inputs are observable in the marketplace. All classes of Level 2 fixed maturity securities are valued using a methodology based on information generated by market transactions involving identical or comparable assets, a discounted cash flow methodology, or a combination of both when necessary. Common inputs for all classes of fixed maturity securities include prices from recently executed transactions of similar securities, marketplace quotes, benchmark yields, spreads off benchmark yields, interest rates and U.S. Treasury or swap curves. Specifically for asset-backed securities, key inputs include prepayment and default projections based on past performance of the underlying collateral and current market data. Fixed maturity securities are primarily assigned to Level 3 in cases where broker/dealer quotes are significant inputs to the valuation and there is a lack of transparency as to whether these quotes are based on information that is observable in the marketplace. Level 3 securities also include private placement debt securities whose fair value is determined using internal models with some inputs that are not market observable.
 Equity Securities
 Level 1 equity securities include publicly traded securities valued using quoted market prices. Level 2 securities are primarily valued using pricing for similar securities, recently executed transactions and other pricing models utilizing market observable inputs. Level 3 securities are primarily priced using broker/dealer quotes and internal models with some inputs that are not market observable.
 Short Term and Other Invested Assets
 Securities that are actively traded or have quoted prices are classified as Level 1. These securities include money market funds and treasury bills. Level 2 primarily includes non-U.S. government securities for which all inputs are market observable. Fixed maturity securities purchased within one year of maturity are classified consistent with fixed maturity securities discussed above. Short-term investments as presented in the tables above differ from the amounts presented on the Consolidated Balance Sheets because certain short-term investments, such as time deposits, are not measured at fair value.
 As of December 31, 2023 and December 31, 2022, there were $ 75 million and $ 72 million of overseas deposits within Other invested assets, which can be redeemed at net asset value in 90 days or less. Overseas deposits are excluded from the fair value hierarchy because their fair value is recorded using the net asset value per share (or equivalent) practical expedient.
 Other Liabilities
 Level 2 securities include currency forward contracts valued using observable market forward rates.

 Significant Unobservable Inputs
 The following tables present quantitative information about the significant unobservable inputs utilized by the Company in the fair value measurements of Level 3 assets. Valuations for assets and liabilities not presented in the tables below are primarily based on broker/dealer quotes for which there is a lack of transparency as to inputs used to develop the valuations. The quantitative detail of these unobservable inputs is neither provided nor reasonably available to the Company. The weighted average rate is calculated based on fair value.

 For fixed maturity securities, an increase to the credit spread assumptions would result in a lower fair value measurement.

These assets and liabilities are not listed in the tables above.

 Note D. Income Taxes
 The CNA Tax Group is included in the consolidated federal income tax return of Loews and its eligible subsidiaries. Loews and the Company have agreed that for each taxable year, the Company will 1) be paid by Loews the amount, if any, by which the Loews consolidated federal income tax liability is reduced by virtue of the inclusion of the CNA Tax Group in the Loews consolidated federal income tax return, or 2) pay to Loews an amount, if any, equal to the federal income tax that would have been payable by the CNA Tax Group filing a separate consolidated tax return. In the event that Loews should have a net operating loss in the future computed on the basis of filing a separate consolidated tax return without the CNA Tax Group, the Company may be required to repay tax recoveries previously received from Loews. This agreement may be canceled by either party upon 30 days written notice.
 For the years ended December 31, 2023, 2022 and 2021, the Company paid $ 263 million, $ 254 million and $ 238 million to Loews related to federal income taxes.
 For 2021 through 2023, Loews and the Company participate in the Internal Revenue Service (IRS) Compliance Assurance Process (CAP), which is a voluntary program for large corporations. Under CAP, the IRS conducts a real-time audit and works contemporaneously with the Company to resolve any issues prior to the filing of the tax return. For 2021 and 2023, the Company was selected to participate in the phase of CAP reserved for taxpayers whose risk of noncompliance does not warrant use of IRS resources. The Company believes that this approach should reduce tax-related uncertainties, if any.
 As of December 31, 2023 and 2022, there were no unrecognized tax benefits.
 The Company recognizes interest accrued related to unrecognized tax benefits and tax refund claims in Income tax (expense) benefit on the Consolidated Statements of Operations. The Company recognizes penalties (if any) in Income tax (expense) benefit on the Consolidated Statements of Operations. During 2023, 2022 and 2021 the Company recognized no interest and no penalties. There were no amounts accrued for interest or penalties as of December 31, 2023 or 2022.

 Total income tax presented above includes foreign tax expense of approximately $ 52 million, $ 1 million and $ 18 million related to pretax income from foreign operations of approximately $ 198 million, $ 141 million and $ 124 million for the years ended December 31, 2023, 2022 and 2021. Foreign tax expense for the year ended December 31, 2022 included a $ 10 million tax benefit for the revaluation of net deferred tax assets related to a U.K. tax rate change.

 As of December 31, 2023, the CNA Tax Group had no loss carryforwards and a tax credit carryforward of $ 2 million which expires in 2033. The foreign operations had loss carryforwards of $ 169 million, which have no expiration. The foreign operations had a tax credit carryforward of $ 9 million, which has no expiration.
 Although realization of deferred tax assets is not assured, management believes it is more likely than not that the recognized net deferred tax asset will be realized through recoupment of ordinary and capital taxes paid in prior carryback years and through future earnings, reversal of existing temporary differences and available tax planning strategies. As a result, no valuation allowance was recorded as of December 31, 2023 or 2022.

 Note E. Claim and Claim Adjustment Expense Reserves
 Claim and claim adjustment expense reserves represent the estimated amounts necessary to resolve all outstanding claims, including incurred but not reported (IBNR) claims as of the reporting date. The Company's reserve projections are based primarily on detailed analysis of the facts in each case, the Company's experience with similar cases and various historical development patterns. Consideration is given to historical patterns such as claim reserving trends and settlement practices, loss payments, pending levels of unpaid claims and product mix, economic, medical and social inflation, and public attitudes. All of these factors can affect the estimation of claim and claim adjustment expense reserves.
 Establishing claim and claim adjustment expense reserves, including claim and claim adjustment expense reserves for catastrophic events that have occurred, is an estimation process. Many factors can ultimately affect the final settlement of a claim and, therefore, the necessary reserve. Changes in the law, results of litigation, medical costs, the cost of repair materials and labor rates can affect ultimate claim costs. In addition, time can be a critical part of reserving determinations since the longer the span between the incidence of a loss and the payment or settlement of the claim, the more variable the ultimate settlement amount can be. Accordingly, short-tail claims, such as property damage claims, tend to be more reasonably estimable than long-tail claims, such as workers' compensation, general liability and professional liability claims. Claim and claim adjustment expense reserves are also maintained for the Company's structured settlement obligations. In developing the claim and claim adjustment expense reserve estimates for structured settlement obligations, the Company's actuaries review mortality experience on an annual basis. Adjustments to prior year reserve estimates, if necessary, are reflected in the results of operations in the period that the need for such adjustments is determined. There can be no assurance that the Company's ultimate cost for insurance losses will not exceed current estimates.

 (1) In conjunction with the Company's adoption of ASU 2018-12, at January 1, 2023, long-term care reserves for policyholders currently receiving benefits were reclassified from Claim and claim adjustment expenses into Future policy benefits and this change was applied retrospectively as of January 1, 2021. See Note A to the Consolidated Financial Statements for additional information.
 (2) Total net incurred does not agree to Insurance claims and policyholders' benefits as reflected on the Consolidated Statements of Operations due to amounts related to retroactive reinsurance deferred gain accounting, the loss on the Excess Workers' Compensation LPT (EWC LPT) and uncollectible reinsurance, which are not reflected in the table above.

 Reserving Methodology
 In developing claim and claim adjustment expense reserve estimates, the Company's actuaries perform detailed reserve analyses that are staggered throughout the year. The data is organized at a reserve group level. Every reserve group is reviewed at least once during the year, but most are reviewed more frequently. The analyses generally review losses gross of ceded reinsurance and apply the ceded reinsurance terms to the gross estimates to establish estimates net of reinsurance. Factors considered include, but are not limited to, the historical pattern and volatility of the actuarial indications, the sensitivity of the actuarial indications to changes in paid and incurred loss patterns, the consistency of claims handling processes, the consistency of case reserving practices, changes in the Company's pricing and underwriting, pricing and underwriting trends in the insurance market and legal, judicial, social and economic trends. In addition to the detailed analyses, the Company reviews actual loss emergence for all products each quarter.
 In developing the loss reserve estimates for property and casualty contracts, the Company generally projects ultimate losses using several common actuarial methods as listed below. The Company reviews the indications from the various methods and applies judgment to select an actuarial point estimate. The carried reserve may differ from the actuarial point estimate as a result of the Company's consideration of the factors noted above as well as the potential volatility of the projections associated with the specific product being analyzed and other factors affecting claims costs that may not be quantifiable through traditional actuarial analysis. The indicated required reserve is the difference between the selected ultimate loss and the inception-to-date paid losses. The difference between the selected ultimate loss and the case incurred or reported loss is IBNR. IBNR includes a provision for development on known cases as well as a provision for late reported incurred claims.
 The most frequently utilized methods to project ultimate losses include the following:
 • Paid development: The paid development method estimates ultimate losses by reviewing paid loss patterns and applying them to accident years with further expected changes in paid loss.
 • Incurred development: The incurred development method is similar to the paid development method, but it uses case incurred losses instead of paid losses.
 • Loss ratio: The loss ratio method multiplies premiums by an expected loss ratio to produce ultimate loss estimates for each accident year.
 • Bornhuetter-Ferguson paid loss: The Bornhuetter-Ferguson paid loss method is a combination of the paid development approach and the loss ratio approach. This method normally determines expected loss ratios similar to the approach used to estimate the expected loss ratio for the loss ratio method.
 • Bornhuetter-Ferguson incurred loss: The Bornhuetter-Ferguson incurred loss method is similar to the Bornhuetter-Ferguson using premiums and paid loss method except that it uses case incurred losses.
 • Frequency times severity: The frequency times severity method multiplies a projected number of ultimate claims by an estimated ultimate average loss for each accident year to produce ultimate loss estimates.
 • Stochastic modeling: The stochastic modeling method produces a range of possible outcomes based on varying assumptions related to the particular product being modeled.
 For many exposures, especially those that can be considered long-tail, a particular accident or policy year may not have a sufficient volume of paid losses to produce a statistically reliable estimate of ultimate losses. In such a case, the Company's actuaries typically assign more weight to the incurred development method than to the paid development method. As claims continue to settle and the volume of paid loss increases, the actuaries may assign additional weight to the paid development method. For most of the Company's products, even the incurred losses for accident or policy years that are early in the claim settlement process will not be of sufficient volume to produce a reliable estimate of ultimate losses. In these cases, the Company may not assign much, if any weight to the paid and incurred development methods. The Company may use the loss ratio, Bornhuetter-Ferguson and/or frequency times severity methods. For short-tail exposures, the paid and incurred development methods can often be relied on sooner, primarily because the Company's history includes a sufficient number of years to cover the entire period over which paid and incurred losses are expected to change. However, the Company may also use the loss ratio, Bornhuetter-Ferguson and/or frequency times severity methods for short-

 tail exposures. For other more complex reserve groups where the above methods may not produce reliable indications, the Company uses additional methods tailored to the characteristics of the specific situation.
 The Company's reserving methodologies for mass tort and A&EP are similar as both are based on detailed reviews of large accounts with estimates of ultimate payments based on the facts in each case and the Company's view of applicable law and coverage litigation.

 Net Prior Year Development
 Changes in estimates of claim and claim adjustment expense reserves, net of reinsurance, for prior years are defined as net prior year loss reserve development (development). These changes can be favorable or unfavorable. The following table presents development recorded for the Specialty, Commercial, International and Corporate & Other segments.

 Unfavorable development of $71 million, $ 64 million, and $ 60 million was recorded within the Corporate & Other segment for the years ended December 31, 2023, 2022, and 2021 largely associated with legacy mass tort abuse claims. The 2022 unfavorable development also included the Diocese of Rochester proposed settlement.

 Segment Development Tables
 For the Specialty, Commercial and International segments, the following tables present further detail and commentary on the development reflected in the financial statements for each of the periods presented. Also presented are loss reserve development tables that illustrate the change over time of reserves established for claim and allocated claim adjustment expenses arising from short-duration insurance contracts for certain lines of business within each of these segments. Not all lines of business or segments are presented based on their context to the Company's overall loss reserves, calendar year reserve development, or calendar year net earned premiums. Insurance contracts are considered to be short-duration contracts when the contracts are not expected to remain in force for an extended period of time.
 The Cumulative Net Incurred Claim and Allocated Claim Adjustment Expenses tables, reading across, show the cumulative net incurred claim and allocated claim adjustment expenses relating to each accident year at the end of the stated calendar year. Changes in the cumulative amount across time are the result of the Company's expanded awareness of additional facts and circumstances that pertain to the unsettled claims. The Cumulative Net Paid Claims and Allocated Claim Adjustment Expenses tables, reading across, show the cumulative amount paid for claims for each accident year as of the end of the stated calendar year. The Net Strengthening or (Releases) of Prior Accident Year Reserves tables, reading across, show the net increase or decrease in the cumulative net incurred accident year claim and allocated claim adjustment expenses during each stated calendar year and indicates whether the reserves for that accident year were strengthened or released.
 The information in the tables is reported on a net basis after reinsurance and does not include the effects of discounting. The information contained in calendar years 2022 and prior is unaudited. Information contained in the tables pertaining to the Company's International segment has been presented at the year-end 2023 foreign currency exchange rates for all periods presented to remove the effects of foreign currency exchange rate changes between calendar years. The Company has presented development information for the Hardy business prospectively from the date of acquisition and is presented as a separate table within the Company's International segment. To the extent the Company enters into a commutation, the transaction is reported on a prospective basis. To the extent that the Company enters into a disposition, the effects of the disposition are reported on a retrospective basis by removing the balances associated with the disposed of business.
 The amounts reported for the cumulative number of reported claims include direct and assumed open and closed claims by accident year at the claimant level. The number excludes claim counts for claims within a policy deductible where the insured is responsible for payment of losses in the deductible layer. Claim count data for certain assumed reinsurance contracts is unavailable.
 IBNR includes reserves for incurred but not reported losses and expected development on case reserves. The Company does not establish case reserves for allocated loss adjusted expenses (ALAE), therefore ALAE reserves are also included in the estimate of IBNR.

 The following table presents further detail of the development recorded for the Specialty segment.

 (1) Due to the nature of the Surety business, average annual percentage payout of ultimate net incurred claim and allocated claim adjustment expenses has been calculated using only the payouts of mature accident years presented in the loss reserve development tables.

 A&EP Reserves
 In 2010, Continental Casualty Company (CCC) together with several of the Company's insurance subsidiaries completed a transaction with National Indemnity Company (NICO), a subsidiary of Berkshire Hathaway Inc., under which substantially all of the Company's legacy A&EP liabilities were ceded to NICO through a LPT. At the effective date of the transaction, the Company ceded approximately $ 1.6 billion of net A&EP claim and allocated claim adjustment expense reserves to NICO under a retroactive reinsurance agreement with an aggregate limit of $ 4 billion. The $ 1.6 billion of claim and allocated claim adjustment expense reserves ceded to NICO was net of $ 1.2 billion of ceded claim and allocated claim adjustment expense reserves under existing third-party reinsurance contracts. The NICO LPT aggregate reinsurance limit also covers credit risk on the existing third-party reinsurance related to these liabilities. The Company paid NICO a reinsurance premium of $ 2 billion and transferred to NICO billed third-party reinsurance receivables related to A&EP claims with a net book value of $ 215 million, resulting in total consideration of $ 2.2 billion.
 In years subsequent to the effective date of the LPT, the Company recognized adverse prior year development on its A&EP reserves resulting in additional amounts ceded under the LPT. As a result, the cumulative amounts ceded under the LPT have exceeded the $ 2.2 billion consideration paid, resulting in the NICO LPT moving into a gain position, requiring retroactive reinsurance accounting. Under retroactive reinsurance accounting, this gain is deferred and only recognized in earnings in proportion to actual paid recoveries under the LPT. Over the life of the contract, there is no economic impact as long as any additional losses incurred are within the limit of the LPT. In a period in which the Company recognizes a change in the estimate of A&EP reserves that increases or decreases the amounts ceded under the LPT, the proportion of actual paid recoveries to total ceded losses is affected and the change in the deferred gain is recognized in earnings as if the revised estimate of ceded losses was available at the effective date of the LPT. The effect of the deferred retroactive reinsurance benefit is recorded in Insurance claims and policyholders' benefits in the Consolidated Statements of Operations.
 The following table presents the impact of the Loss Portfolio Transfer on the Consolidated Statements of Operations.

 Net unfavorable prior year development of $ 86 million, $ 92 million and $ 143 million was recognized before consideration of cessions to the LPT for the years ended December 31, 2023, 2022 and 2021. The unfavorable development in 2023, 2022 and 2021 was primarily driven by higher than anticipated defense and indemnity costs on known direct asbestos and environmental accounts and a reduction in estimated reinsurance recoverable. Additionally, in both 2022 and 2021, the Company released $ 5 million of its provision for uncollectible third-party reinsurance. The Company did not release any of its provision for uncollectible third-party reinsurance in 2023.
 As of December 31, 2023 and 2022, the cumulative amounts ceded under the LPT were $ 3.6 billion and $ 3.5 billion. The unrecognized deferred retroactive reinsurance benefit was $ 417 million and $ 425 million as of December 31, 2023 and 2022 and is included within Other liabilities on the Consolidated Balance Sheets.
 NICO established a collateral trust account as security for its obligations to the Company. The fair value of the collateral trust account was $ 2.5 billion as of December 31, 2023. In addition, Berkshire Hathaway Inc. guaranteed the payment obligations of NICO up to the aggregate reinsurance limit as well as certain of NICO's performance obligations under the trust agreement. NICO is responsible for claims handling and billing and collection from third-party reinsurers related to the majority of the Company's A&EP claims.

 Excess Workers' Compensation LPT
 On February 5, 2021, CCC completed a transaction with Cavello Bay Reinsurance Limited (Cavello), a subsidiary of Enstar Group Limited, under which certain legacy excess workers' compensation (EWC) liabilities were ceded to Cavello. Under the terms of the transaction, based on reserves in place as of January 1, 2020, the Company ceded approximately $ 690 million of net EWC claim and allocated claim adjustment expense reserves to Cavello under an LPT with an aggregate limit of $ 1 billion. The Company paid Cavello a reinsurance premium of $ 697 million, less claims paid between January 1, 2020 and the closing date of the agreement of $ 64 million. After transaction costs, the Company recognized an after-tax loss of approximately $ 12 million in the Corporate & Other segment in the first quarter of 2021 related to the EWC LPT.
 As of December 31, 2023, the cumulative amount ceded under the EWC LPT was $ 690 million.
 Cavello established a collateral trust as security for its obligations to the Company. The fair value of the collateral trust was $ 440 million as of December 31, 2023.

 Note F. Future Policy Benefits Reserves
 Future policy benefits reserves are associated with the Company's run-off long-term care business, which is included in the Life & Group segment, and relate to policyholders that are currently receiving benefits, including claims that have been incurred but are not yet reported, as well as policyholders that are not yet receiving benefits.
 The determination of Future policy benefits reserves requires management to make estimates and assumptions about expected policyholder experience over the remaining life of the policy. Since policies may be in force for several decades, these assumptions are subject to significant estimation risk. As a result of this variability, the Company's future policy benefits reserves may be subject to material increases if actual experience develops adversely to the Company's expectations.
 The LFPB is computed using the net level premium method, which incorporates cash flow assumptions and discount rate assumptions. As a result of the modified retrospective adoption of ASU 2018-12, the Company's NPR calculation incorporates the original locked in discount rate and the reserve balance as of the transition date of January 1, 2021. The key cash flow assumptions used to estimate the LFPB are morbidity, persistency (inclusive of mortality), anticipated future premium rate increases and expenses. The carried LFPB discount rate is determined using the upper-medium grade fixed income instrument yield curve.
 The Company has elected to update the NPR and the LFPB for actual experience on a quarterly basis. A quarterly assessment is also made as to whether evidence suggests that cash flow assumptions should be updated. Annually in the third quarter, actuarial analysis is performed on policyholder morbidity, persistency, premium rate increases and expense experience, which, combined with judgment, informs the setting of updated cash flow assumptions used to estimate the LFPB.
 The cash flow assumption updates completed in the third quarter of 2023 resulted in an $ 8 million pretax increase in the LFPB. Persistency updates were unfavorable due to revisions to lapse rates. Morbidity updates were favorable driven by claim severity assumption updates, and there was a favorable impact from outperformance on premium rate assumptions. Adjusted to reflect the application of the LDTI accounting standard, the cash flow assumption updates completed in the third quarter of 2022 resulted in a $ 186 million pretax increase to the LFPB, primarily driven by the unfavorable impact of increased cost of care inflation offset by favorable premium rate assumptions.

 The following table summarizes balances and changes in the LFPB.

 For the years ended December 31, 2023 and 2022, immediate charges to net income resulting from adverse development that caused the NPR to exceed 100% for certain cohorts were $ 164 million and $ 178 million. For the years ended December 31, 2023 and 2022, the portion of losses recognized in a prior period due to NPR exceeding 100% for certain cohorts which, due to favorable development, was reversed through net income was $ 42 million and $ 12 million.

 Note G. Legal Proceedings, Contingencies and Guarantees
 The Company is a party to various claims and litigation incidental to its business, which, based on the facts and circumstances currently known, are not material to the Company's results of operations or financial position.
 Guarantees
 The Company has provided guarantees, if the primary obligor fails to perform, to holders of structured settlement annuities issued by a previously owned subsidiary. As of December 31, 2023, the potential amount of future payments the Company could be required to pay under these guarantees was approximately $ 1.5 billion, which will be paid over the lifetime of the annuitants. The Company does not believe any payment is likely under these guarantees, as the Company is the beneficiary of a trust that must be maintained at a level that approximates the discounted reserves for these annuities.

 Note H. Reinsurance
 The Company cedes insurance to reinsurers to limit its maximum loss, provide greater diversification of risk, minimize exposures on larger risks and to exit certain lines of business. The ceding of insurance does not discharge the primary liability of the Company. A credit exposure exists with respect to reinsurance ceded to the extent that any reinsurer is unable to meet its obligations. A collectibility exposure also exists to the extent that the reinsurer disputes the liabilities assumed under reinsurance agreements. Property and casualty reinsurance coverages are tailored to the specific risk characteristics of each product line and the Company's retained amount varies by type of coverage. Reinsurance contracts are purchased to protect specific lines of business such as property and workers' compensation. Corporate catastrophe reinsurance is also purchased for property and workers' compensation exposure. The Company also utilizes facultative reinsurance in certain lines. In addition, the Company assumes reinsurance primarily through Hardy and as a member of various reinsurance pools and associations.
 The following table presents the amounts receivable from reinsurers.

 The Company has established an allowance for uncollectible voluntary reinsurance receivables which relates to both amounts already billed on ceded paid losses as well as ceded reserves that will be billed when losses are paid in the future. The following table summarizes the outstanding amount of voluntary reinsurance receivables, gross of any collateral arrangements, by financial strength rating.

 (1) Expected credit losses for legacy A&EP receivables are ceded to NICO and the reinsurance limit on the LPT has not been exhausted, therefore no allowance is recorded for these receivables and they are excluded from the table above. Refer to Note E to the Consolidated Financial Statements for information regarding the LPT. The Company has also excluded receivables from involuntary pools.
 The Company attempts to mitigate its credit risk related to reinsurance by entering into reinsurance arrangements with reinsurers that have credit ratings above certain levels and by obtaining collateral. On a limited basis, the Company may enter into reinsurance agreements with reinsurers that are not rated, primarily captive reinsurers. Receivables from captive reinsurers are backed by collateral arrangements and comprise the majority of the voluntary reinsurance receivables within the B- to B++ rating distribution in the table above. The primary methods of obtaining collateral are through reinsurance trusts, letters of credit and funds withheld balances. Such collateral, limited by the balance of open recoverables, was approximately $ 3.6 billion and $ 3.7 billion as of December 31, 2023 and 2022.
 The Company's largest recoverables from a single reinsurer as of December 31, 2023, including ceded unearned premium reserves, were approximately $ 1.8 billion from subsidiaries of the Berkshire Hathaway Insurance Group, $ 576 million from Cavello Bay Reinsurance Limited and $ 410 million from the Swiss Reinsurance Group. These amounts are substantially collateralized or otherwise secured. The recoverable from subsidiaries of the Berkshire Hathaway Insurance Group includes amounts related to third-party reinsurance for which

 NICO has assumed the credit risk under the terms of the LPT as discussed in Note E to the Consolidated Financial Statements.
 The effects of reinsurance on earned premiums and written premiums are presented in the following tables.

 Included in the direct and ceded earned premiums for the years ended December 31, 2023, 2022 and 2021 are $ 2,907 million, $ 3,270 million and $ 3,638 million related to property business that is 100% reinsured under a significant third-party captive program. The third-party captives that participate in this program are affiliated with the non-insurance company policyholders, therefore this program provides a means for the policyholders to self-insure this property risk. The Company receives and retains a ceding commission.
 Insurance claims and policyholders' benefits reported on the Consolidated Statements of Operations are net of estimated reinsurance recoveries of $ 2,772 million, $ 2,631 million and $ 3,058 million for the years ended December 31, 2023, 2022 and 2021, including $ 1,512 million, $ 1,796 million and $ 2,003 million, respectively, related to the significant third-party captive program discussed above.
 Long-term care premiums are from long-duration contracts; property and casualty premiums are from short-duration contracts.

 CCC is a member of the Federal Home Loan Bank of Chicago (FHLBC). FHLBC membership provides participants with access to additional sources of liquidity through various programs and services. As a requirement of membership in the FHLBC, CCC held $ 5 million of FHLBC stock as of December 31, 2023 giving it immediate access to approximately $ 106 million of additional liquidity. As of December 31, 2023 and 2022, CCC had no outstanding borrowings from the FHLBC.
 During 2023, the Company amended and restated its existing credit agreement with a syndicate of banks. The agreement provides a five-year $ 250 million senior unsecured revolving credit facility which is intended to be used for general corporate purposes. At the Company's election, the commitments under the agreement may be increased from time to time up to an additional aggregate amount of $ 100 million, and two one-year extensions are available prior to any anniversary of the closing date, each subject to applicable consents. Under the agreement, the Company is required to pay a facility fee which would adjust in the event of a change in the Company's ratio of consolidated indebtedness to consolidated total capitalization, calculated in accordance with the agreement. The agreement includes several covenants, including maintenance of a minimum consolidated net worth and a specified ratio of consolidated indebtedness to consolidated total capitalization. The minimum consolidated net worth, as defined, at December 31, 2023, was $ 8.7 billion. The calculation of minimum consolidated net worth excludes AOCI. As of December 31, 2023 and 2022, the Company had no outstanding borrowings under the credit agreement.
 The Company's debt obligations contain customary covenants for investment grade issuers. The Company was in compliance with all covenants as of and for the years ended December 31, 2023 and 2022.

 Note J. Benefit Plans
 Pension and Postretirement Health Care Benefit Plans
 CNA sponsors noncontributory defined benefit pension plans, primarily through the CNA Retirement Plan, covering certain eligible employees. These plans are closed to new entrants. CNA's funding policy for defined benefit pension plans is to make contributions in accordance with applicable governmental regulatory requirements with consideration of the funded status of the plans.
 Effective January 1, 2000, the CNA Retirement Plan was closed to new participants. Existing participants at that time were given a choice to either continue to accrue benefits under the CNA Retirement Plan or to cease accruals effective December 31, 1999. Employees who chose to continue to accrue benefits under the plan received benefits in accordance with plan provisions through June 30, 2015 as discussed further below. Participants who elected to cease accruals at December 31, 1999 received the present value of their accrued benefit in an accrued pension account that is credited with interest based on the annual rate of interest on 30-year Treasury securities. These employees also receive certain enhanced employer contributions in the CNA 401k Plan.
 Effective June 30, 2015, the Company eliminated future benefit accruals associated with the CNA Retirement Plan. Participants who were continuing to accrue benefits under the CNA Retirement Plan up until that date are entitled to an accrued benefit payable based on their eligible compensation and accrued service through June 30, 2015. These affected participants now also receive enhanced employer contributions in the CNA 401k Plan similar to participants who elected to cease accruals effective December 31, 1999. Employees who elected to cease accruals effective December 31, 1999 were not affected by this curtailment.
 In 2023, the CNA Retirement Plan paid $ 80 million to settle its obligation to certain retirees through the purchase of a group annuity contract from a third party insurance company (group annuity purchase). The group annuity purchase reduced the plan's projected benefit obligation by $ 86 million.
 CNA provides certain postretirement health care benefits to eligible retired employees, their covered dependents and their beneficiaries primarily through the CNA Health and Group Benefits Program. These postretirement benefits have largely been eliminated for active employees.

 The following table presents a reconciliation of benefit obligations and plan assets.

 The accumulated benefit obligation for all defined benefit pension plans was $ 1,807 million and $ 1,931 million as of December 31, 2023 and 2022. Changes for the years ended December 31, 2023 and 2022 include an actuarial loss of $ 27 million and a gain of $ 514 million primarily driven by changes in the discount rate used to determine the defined benefit pension obligations.
 For pension plans with a benefit obligation in excess of plan assets, the benefit obligation was $ 46 million and $ 49 million and the aggregate plan assets were $ 0 at December 31, 2023 and 2022.

 To determine the discount rate assumption as of the year-end measurement date for the CNA Retirement Plan and CNA Health and Group Benefits Program, the Company considered the estimated timing of plan benefit payments and available yields on high quality fixed income debt securities. For this purpose, high quality is considered a rating of Aa or better by Moody's Investors Service, Inc. (Moody's) or a rating of AA or better from Standard & Poor's (S&P). The Company reviewed several yield curves constructed using the cash flow characteristics of the plans as well as bond indices as of the measurement date. The trend of those data points was also considered.
 In determining the expected long-term rate of return on plan assets assumption for the CNA Retirement Plan, CNA considered the historical performance of the benefit plan investment portfolio as well as long-term market return expectations based on the investment mix of the portfolio and the expected investment horizon.
 The CNA Health and Group Benefits Program has limited its share of the health care trend rate to a cost-of-living adjustment of 4 % per year. For all participants, the employer subsidy on health care costs will not increase by more than 4 % per year. As a result, the assumed health care cost trend rate used in measuring the accumulated postretirement benefit obligation for the CNA Health and Group Benefits Program was 4 % per year in 2023, 2022 and 2021.
 CNA employs a total return approach whereby a mix of equity, limited partnerships and fixed maturity securities are used to maximize the long-term return of retirement plan assets for a prudent level of risk and to manage cash flows according to plan requirements. The target allocation of plan assets is 0 % to 40 % invested in equity securities and limited partnerships, with the remainder primarily invested in fixed maturity securities. Alternative investments, including limited partnerships, are used to enhance risk adjusted long-term returns while improving portfolio diversification. The intent of this strategy is to minimize the Company's expense related to funding the plan by generating investment returns that exceed the growth of the plan liabilities over the long run. Risk tolerance is established after careful consideration of the plan liabilities, plan funded status and corporate financial conditions.
 As of December 31, 2023, the Plan had committed approximately $ 100 million to future capital calls from various third-party limited partnership investments in exchange for an ownership interest in the related partnerships. Derivatives may be used to gain market exposure in an efficient and timely manner. Investment risk is measured and monitored on an ongoing basis through annual liability measurements, periodic asset/liability studies and quarterly investment portfolio reviews.

 (1) Certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. The fair value amounts presented in this table for these investments are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the Plan's Statement of Financial Position.
 The limited partnership investments held within the plan are recorded at fair value, which represents the plan's share of net asset value of each partnership, as determined by each limited partnership's general partner. Limited partnerships comprising 94 % and 62 % of the carrying value as of December 31, 2022 and 2021 were invested in private debt and equity. Limited partnerships comprising 6 % and 38 % of the carrying value as of December 31, 2023 and 2022 employ hedge fund strategies. Private debt and equity funds cover a broad range of investment strategies including buyout, private credit, growth capital and distressed investing. Hedge fund strategies include both long and short positions in fixed income, equity and derivative investments.
 For a discussion of the fair value levels and the valuation methodologies used to measure fixed maturity securities, equities, derivatives and short-term investments, see Note C to the Consolidated Financial Statements.

 2029-2033

 In 2024, CNA expects to contribute $ 6 million to its pension plans and $ 1 million to its postretirement health care benefit plans.
 Savings Plans
 CNA sponsors savings plans, which are generally contributory plans that allow eligible employees to contribute a maximum of 50 % of their eligible compensation, subject to certain limitations prescribed by the IRS. The Company contributes matching amounts to participants amounting to 100 % of the first 6 % of annual eligible compensation contributed by the employee. In addition, eligible employees also receive a Company contribution of 5 % of their annual eligible compensation, referred to as a basic contribution. Company contributions vest ratably over participants first five years of service.
 Benefit expense for the Company's savings plans was $ 82 million, $ 71 million and $ 65 million for the years ended December 31, 2023, 2022 and 2021.

 Note K. Stock-Based Compensation
 The CNAF Incentive Compensation Plan (the Plan) authorizes the grant of stock-based compensation to certain management personnel for up to 16 million shares of CNAF common stock. The Plan provides for awards of stock options, stock appreciation rights (SARs), restricted shares, restricted stock units (RSUs), performance-based RSUs and performance share units. Grants to employees are not designed to be spring-loaded. The number of remaining shares available for the granting of stock-based compensation under the Plan as of December 31, 2023 was approximately 3.6 million.
 Substantially all of the Company's stock-based compensation is awarded under the Annual Performance Share Plan (PSP). The PSP provides officers with an opportunity to earn an award based upon attainment of specific performance goals achieved over a one-year performance period. Awards are granted in the form of performance share units at the beginning of each performance year and are generally subject to a two-year cliff vesting period after the Company's annual performance has been determined. The performance share units become payable within a range of 0 % to 200 % of the number of performance share units initially granted.
 Additionally, the Company may grant RSUs under the Plan in certain circumstances. These awards generally vest over a one to three-year service period following the grant date.
 Stock-based compensation that is not fully vested prior to termination is generally forfeited upon termination, except in cases of retirement, death or disability, and as otherwise provided by contractual obligations. The fair value of stock-based compensation awards is based on the market value of the Company's common stock as of the date of grant, except for awards made to foreign participants, which is based on the current market value of the Company's common stock. Payments made under the PSP are made entirely in shares of common stock granted under the Plan, except for awards made to foreign participants, which are paid in cash.
 The Company recorded stock-based compensation expense related to the Plan of $ 38 million, $ 36 million and $ 32 million for the years ended December 31, 2023, 2022 and 2021. The related income tax benefit recognized was $ 8 million, $ 8 million and $ 6 million for the years ended December 31, 2023, 2022 and 2021. The compensation cost not yet recognized was $ 44 million, and the weighted average period over which it is expected to be recognized is 1.8 years as of December 31, 2023.
 The total fair value of RSUs and performance share units that vested during the years ended December 31, 2023, 2022 and 2021 was $ 34 million, $ 35 million and $ 36 million, respectively.
 The weighted average grant date fair value for RSUs and performance share units granted during the years ended December 31, 2023, 2022 and 2021 was $ 37.06, $ 46.78 and $ 45.82, respectively.

 In the fourth quarter of 2023, the Company committed to consolidate some of its offices, which resulted in a $ 24 million charge within Other operating expense on the Consolidated Statement of Operations, recorded in the Corporate & Other Segment. The charge primarily relates to the abandonment of certain fixed assets and operating lease ROU assets that are no longer in use.

 Note N. Stockholders' Equity and Statutory Accounting Practices
 Common Stock Dividends
 There are no restrictions on the retained earnings or net income of CNAF with regard to payment of dividends to its stockholders. However, given the holding company nature of CNAF, its ability to pay a dividend is dependent on the receipt of dividends from its subsidiaries, particularly CCC, which directly or indirectly owns the vast majority of all significant subsidiaries. See the Statutory Accounting Practices section below for a discussion of the regulatory restrictions on CCC's availability to pay dividends.
 CNAF's ability to pay dividends may be indirectly limited by the minimum consolidated net worth covenant in the Company's line of credit agreement. See Note I to the Consolidated Financial Statements for further discussion of the Company's debt obligations.
 Statutory Accounting Practices
 CNAF's insurance subsidiaries are domiciled in various jurisdictions. These subsidiaries prepare statutory financial statements in accordance with accounting practices prescribed or permitted by the respective jurisdictions' insurance regulators. Domestic prescribed statutory accounting practices are set forth in a variety of publications of the National Association of Insurance Commissioners (NAIC) as well as state laws, regulations and general administrative rules. These statutory accounting principles vary in certain respects from GAAP. In converting from statutory accounting principles to GAAP, the more significant adjustments include deferral of policy acquisition costs and the inclusion of net unrealized holding gains or losses in stockholders' equity relating to certain fixed maturity securities.
 The Company has a prescribed practice as it relates to the accounting under Statement of Statutory Accounting Principles No. 62R, Property and Casualty Reinsurance, paragraphs 87 and 88 in conjunction with the 2010 LPT with NICO which is further discussed in Note E to the Consolidated Financial Statements. The prescribed practice allows the Company to aggregate all third-party A&EP reinsurance balances administered by NICO in Schedule F and to utilize the LPT as collateral for the underlying third-party reinsurance balances for purposes of calculating the statutory reinsurance penalty. This prescribed practice increased statutory capital and surplus by $ 92 million and $ 74 million at December 31, 2023 and 2022.
 The payment of dividends by CNAF's insurance subsidiaries without prior approval of the insurance department of each subsidiary's domiciliary jurisdiction is generally limited by formula. Dividends in excess of these amounts are subject to prior approval by the respective insurance regulator.
 Dividends from CCC are subject to the insurance holding company laws of the State of Illinois, the domiciliary state of CCC. Under these laws, ordinary dividends, or dividends that do not require prior approval by the Illinois Department of Insurance (the Department), are determined based on the greater of the prior year's statutory net income or 10% of statutory surplus as of the end of the prior year, as well as the timing and amount of dividends paid in the preceding twelve months. Additionally, ordinary dividends may only be paid from earned surplus, which is calculated by removing unrealized gains from unassigned surplus. As of December 31, 2023, CCC is in a positive earned surplus position. The maximum allowable dividend CCC could pay during 2024 that would not be subject to the Department's prior approval is $ 1,105 million, less dividends paid during the preceding twelve months measured at that point in time. CCC paid dividends of $ 1,055 million in 2023. The actual level of dividends paid in any year is determined after an assessment of available dividend capacity, holding company liquidity and cash needs as well as the impact the dividends will have on the statutory surplus of the applicable insurance company.

 Combined statutory capital and surplus and statutory net income (loss) for the Combined Continental Casualty Companies are presented in the table below, determined in accordance with accounting practices prescribed or permitted by insurance and/or other regulatory authorities.

 (1) Information derived from the statutory-basis financial statements to be filed with insurance regulators.
 CNAF's domestic insurance subsidiaries are subject to risk-based capital (RBC) requirements. RBC is a method developed by the NAIC to determine the minimum amount of statutory capital appropriate for an insurance company to support its overall business operations in consideration of its size and risk profile. The formula for determining the amount of RBC specifies various factors, weighted based on the perceived degree of risk, which are applied to certain financial balances and financial activity. The adequacy of a company's actual capital is evaluated by a comparison to the RBC results, as determined by the formula. Companies below minimum RBC requirements are classified within certain levels, each of which requires specified corrective action.
 The statutory capital and surplus presented above for CCC was approximately 225 % and 238 % of company action level RBC as of December 31, 2023 and 2022. Company action level RBC is the level of RBC which triggers a heightened level of regulatory supervision. The statutory capital and surplus of the Company's foreign insurance subsidiaries, which is not significant to the overall statutory capital and surplus, also met or exceeded their respective regulatory and other capital requirements.

 Note P. Business Segments

 The Company's property and casualty commercial insurance operations are managed and reported in three business segments: Specialty, Commercial and International. These three segments are collectively referred to as Property & Casualty Operations. Specialty provides management and professional liability and other coverages through property and casualty products and services using a network of brokers, independent agencies and managing general underwriters. Commercial works with a network of brokers and independent agents to market a broad range of property and casualty insurance products to all types of insureds targeting small business, construction, middle markets and other commercial customers. The International segment underwrites property and casualty coverages on a global basis through a branch operation in Canada, a European business consisting of insurance companies based in the U.K. and Luxembourg and Hardy, the Company's Lloyd's syndicate.
 The Company's operations outside of Property & Casualty Operations are managed and reported in two segments: Life & Group and Corporate & Other. Life & Group primarily includes the results of the long-term care business that is in run-off. Corporate & Other primarily includes certain corporate expenses, including interest on corporate debt and the results of certain property and casualty business in run-off, including CNA Re, A&EP, a legacy portfolio of EWC policies and certain legacy mass tort reserves.
 The accounting policies of the segments are the same as those described in Note A to the Consolidated Financial Statements. The Company manages most of its assets on a legal entity basis, while segment operations are generally conducted across legal entities. As such, only Insurance and Reinsurance receivables, Insurance reserves, Deferred acquisition costs, Goodwill and Deferred non-insurance warranty acquisition expense and revenue are readily identifiable for individual segments. Distinct investment portfolios are not maintained for every individual segment; accordingly, allocation of assets to each segment is not performed. Therefore, a significant portion of Net investment income and Net investment gains or losses are allocated primarily based on each segment's net carried insurance reserves, as adjusted. All significant intersegment income and expense have been eliminated. Income taxes have been allocated on the basis of the taxable income of the segments.
 Approximately 11 %, 10 % and 10 % of the Company's direct written premiums were derived from outside the United States for the years ended December 31, 2023, 2022 and 2021.
 In the following tables, certain financial measures are presented to provide information used by management to monitor the Company's operating performance. Management utilizes these financial measures to monitor the Company's insurance operations and investment portfolio.
 The performance of the Company's insurance operations is monitored by management through core income (loss), which is derived from certain income statement amounts. The Company's investment portfolio is monitored by management through analysis of various factors including unrealized gains and losses on securities, portfolio duration and exposure to market and credit risk.
 Core income (loss) is calculated by excluding from net income (loss) the after-tax effects of net investment gains or losses. The calculation of core income (loss) excludes net investment gains or losses because net investment gains or losses are generally driven by economic factors that are not necessarily reflective of our primary operations.

 The Company's results of operations and selected balance sheet items by segment are presented in the following tables.

Prior period amounts in the financial statements have been adjusted to reflect application of the new guidance. See Note A to the Consolidated Financial Statements for additional information.
 Core income (loss) and Net income (loss) for 2022 decreased from what was previously reported under legacy accounting guidance generally driven by the cumulative effect of assumption differences and differences in reserving methodologies between legacy and new accounting guidance.
 Core income (loss) and Net income (loss) for the third quarter of 2022 decreased $ 170 million from what was previously reported under legacy accounting guidance, primarily related to the third quarter 2022 annual review of cash flow reserving assumptions. Under legacy accounting guidance, the third quarter 2022 gross premium valuation assessment indicated a pretax margin of $ 125 million and no unlocking event occurred. Under the new guidance favorable changes to the upper-medium grade fixed income instrument discount rate were recorded through Accumulated other comprehensive income quarterly, while the net unfavorable impact of increased cost of care inflation offset by favorable premium rate action assumptions was recorded in income.
 Other comprehensive income (loss), net of tax, for 2022 decreased from what was previously reported under legacy accounting guidance driven by increases in the upper-medium grade fixed-income instrument yield, which was used as the discount rate to re-measure the LFPB.

 Note R. Related Party Transactions
 The Company reimburses Loews for, or pays directly, fees and expenses of investment facilities and services provided to the Company. Additionally, the Company provides investment-related processing services to Loews and charges Loews for these services.

For a detailed description of the income tax agreement with Loews see Note D to the Consolidated Financial Statements. In 2021, the Company wrote an appeal bond for Loews at standard rates, which was increased in 2022, resulting in additional premium from Loews. The aforementioned appeal bond expired in December 2022. In addition, the Company writes, at standard rates, a limited amount of insurance for Loews and its subsidiaries. The earned premiums for each of the years ended December 31, 2023, 2022 and 2021 were $ 2 million, $ 3 million, and $ 2 million.

 Note S. Non-Insurance Revenues from Contracts with Customers
 Non-Insurance revenue is recognized when obligations under the terms of a contract with a customer are satisfied; generally this occurs over time as obligations are fulfilled. Revenue is measured as the amount of consideration the Company expects to receive in exchange for providing services.
 Deferred Non-Insurance Warranty Revenue

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 To the Board of Directors and Stockholders of
 Chicago, Illinois
 Opinions on the Financial Statements and Internal Control over Financial Reporting
 We have audited the accompanying consolidated balance sheets of CNA Financial Corporation (an affiliate of Loews Corporation) and subsidiaries (the "Company") as of December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive income (loss), cash flows, and stockholders' equity, 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 A to the financial statements, the Company has changed its method of accounting for measurement and disclosure of long-duration contracts effective January 1, 2023, using the modified retrospective method applied as of the transition date of January 1, 2021, due to adoption of ASU 2018-12, Financial Services-Insurance (Topic 944): 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 Management's Report on Internal Control over Financial Reporting. 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 Matters
 The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters 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 matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.
 Claim and claim adjustment expense reserves - Property & Casualty - Refer to Notes A and E to the financial statements.
 Critical Audit Matter Description
 The estimation of property and casualty claim and claim adjustment expense reserves ("P&C claim and claim adjustment expense reserves"), including those claims that are incurred but not reported, requires significant judgment. Estimating P&C claim and claim adjustment expense reserves is subject to a high degree of variability as it involves complex estimates that are generally derived using a variety of actuarial estimation techniques and numerous assumptions and expectations about future events, many of which are highly uncertain. Modest changes in judgments and assumptions can materially impact the valuation of these liabilities, particularly for claims with longer-tailed exposures such as workers' compensation, general liability and professional liability claims and certain shorter-tailed exposures, such as surety.
 Given the significant judgments made by management in estimating P&C claim and claim adjustment expense reserves, auditing P&C claim and claim adjustment expense reserves required a high degree of auditor judgment and an increased extent of effort, including the involvement of our actuarial specialists.
 How the Critical Audit Matter Was Addressed in the Audit
 Our audit procedures related to P&C claim and claim adjustment expense reserves included the following, among others:
 • We tested the effectiveness of controls related to the determination of P&C claim and claim adjustment expense reserves, including those controls related to the estimation of and management's review of P&C claim and claim adjustment expense reserves.
 • We tested the underlying data, including historical claims, that served as the basis for the actuarial analyses, to test that the inputs to the actuarial estimates were accurate and complete.
 • With the assistance of our actuarial specialists:

 We developed a range of independent estimates of P&C claim and claim adjustment expense reserves and compared the recorded reserves to our range of estimates.
 We performed a retrospective review which involved comparing our prior year estimates of expected incurred losses to actual experience during the most recent year to identify potential bias in the Company's determination of P&C claim and claim adjustment expense reserves.
 Future policy benefit reserves - Long-Term Care - Refer to Notes A and F to the financial statements.
 Critical Audit Matter Description
 The estimation of long-term care future policy benefit reserves ("LTC future policy benefit reserves") requires significant judgment in the selection of key assumptions, including morbidity and persistency (inclusive of mortality). Estimating future experience for long term care policies is subject to significant estimation risk as the required projection period spans several decades. Morbidity and persistency experience can be volatile and modest changes in each of these assumptions can materially impact the valuation of these liabilities.
 Given the significant judgments made by management in estimating LTC future policy benefit reserves, auditing LTC future policy benefit reserves required a high degree of auditor judgment and an increased extent of effort, including the involvement of our actuarial specialists.
 How the Critical Audit Matter Was Addressed in the Audit
 Our audit procedures related to LTC future policy benefit reserves included the following, among others:
 • We tested the effectiveness of controls related to the determination of LTC future policy benefit reserves, including those controls related to the estimation of and management's review of LTC future policy benefit reserves and determination of key assumptions.
 • We tested the underlying data, including demographic and historical claims data, that served as the basis for the actuarial analyses, to test that the inputs to the actuarial estimates were accurate and complete.
 • With the assistance of our actuarial specialists:
 We independently recalculated cohort level LTC future policy benefit reserves and compared our estimates to the recorded reserves.
 We evaluated the judgments made by management in setting assumptions, including comparing those assumptions to the Company's historical experience used as the basis for setting those assumptions.
 For a sample of policies, we evaluated management's estimate of future cash flows. This included confirming that assumptions were applied as intended.

 MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
 The management of CNA Financial Corporation (CNAF or the Company) is responsible for establishing and maintaining adequate internal control over financial reporting. CNAF's internal control system was designed to provide reasonable assurance to the Company's management, its Audit Committee and Board of Directors regarding the preparation and fair presentation of published financial statements.
 There are inherent limitations to the effectiveness of any internal control or system of control, however well designed, including the possibility of human error and the possible circumvention or overriding of such controls or systems. Moreover, because of changing conditions the reliability of internal controls may vary over time. As a result even effective internal controls can provide no more than reasonable assurance with respect to the accuracy and completeness of financial statements and their process of preparation.
 CNAF management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2023. In making this assessment, it has used the criteria set forth by the 2013 Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control - Integrated Framework. Based on those criteria and our assessment we believe that, as of December 31, 2023, the Company's internal control over financial reporting was effective.
 CNAF's independent registered public accountant, Deloitte & Touche LLP, has issued an audit report on the Company's internal control over financial reporting. This report appears on page 145.
