 Item 1. Business
 See the "Glossary of terms and acronyms" for definitions and descriptions of terms used throughout this annual report.

 A. General
 We are a holding company and through wholly-owned subsidiaries we provide private mortgage insurance, other mortgage credit risk management solutions, and ancillary services. In 2024, our total revenues were $1.2 billion and our primary NIW was $55.7 billion. As of December 31, 2024, our direct primary IIF was $295.4 billion and our direct primary RIF was $78.8 billion. For further information about our results of operations, see our consolidated financial statements in Item 8 and our MD&A in Item 7. As of December 31, 2024, our principal mortgage insurance subsidiary, MGIC, was licensed in all 50 states of the United States, the District of Columbia, Puerto Rico and Guam. During 2024, we wrote new insurance in each of those jurisdictions.
 2025 BUSINESS STRATEGIES
 Our business strategies continue to be to 1) maximize the value we create through our mortgage credit enhancement activities; 2) differentiate ourselves through our customer experience; 3) establish a competitive advantage through our digital and analytical capabilities; 4) excel at acquiring, managing and distributing mortgage credit risk and the related capital; 5) maintain financial strength through economic cycles; and 6) foster an environment that embraces diversity and best positions our people to succeed.
 2024 ACCOMPLISHMENTS
 Following are several of our 2024 accomplishments that furthered our business strategies.
 • Earned $763 million of net income ($2.89 per diluted share) for the year, compared to $713 million ($2.49 per diluted share) in 2023.
 • Expanded our reinsurance program by finalizing quota share reinsurance covering the majority of our 2025 and 2026 NIW and placing a forward-commitment excess of loss reinsurance agreement covering 2024 NIW. These transactions allow us to better manage our risk profile, and they provide an alternative source of capital.

 OVERVIEW OF THE PRIVATE MORTGAGE INSURANCE INDUSTRY AND ITS OPERATING ENVIRONMENT
 We established the modern PMI industry in 1957 to provide a private market alternative to federal government insurance programs. PMI covers losses from homeowner defaults on residential mortgage loans, reducing, and in some instances eliminating, the loss to the insured institution.
 Fannie Mae and Freddie Mac ("the GSEs") have been the major purchasers of the mortgage loans underlying new insurance written by private mortgage insurers. The GSEs purchase residential mortgage loans as part of their governmental mandate to provide liquidity in the secondary mortgage market. The GSEs cannot buy low down payment mortgage loans without certain forms of credit enhancement. Private mortgage insurance has generally been purchased by lenders in primary mortgage market transactions to satisfy this credit enhancement requirement. Therefore, PMI facilitates the sale of low down payment mortgages in the secondary mortgage market to the GSEs and plays an important role in the housing finance system by assisting consumers, especially first-time and low- and medium-wealth homebuyers, to finance homes with low down payment mortgages. PMI also reduces the regulatory capital that depository institutions are required to hold against certain low down payment mortgages that they hold as assets.
 Because the GSEs have been the major purchasers of the mortgages underlying new insurance written by private mortgage insurers, the PMI industry in the U.S. is defined in large part by the requirements and practices of the GSEs. These requirements and practices, as well as those of the federal regulators that oversee the GSEs and lenders, impact the operating results and financial performance of private mortgage insurers. In 2008, the federal government took control of the GSEs through a conservatorship process. The FHFA is the conservator of the GSEs and has the authority to control and direct their operations.
 In recent years, primarily at the direction of FHFA, the GSEs have been focused on, among other things, the promotion of access, affordability, and equitable housing initiatives. In 2022 the GSEs each published Equitable Housing Finance Plans ("Plans"). Updated Plans were subsequently published by each GSE in the spring of 2024. The Plans seek to advance equity in housing finance over a three-year period and include potential changes to the GSEs' business practices and policies. Specifically relating to mortgage insurance, (1) Fannie Mae's Plan includes the creation of special purpose credit program(s) ("SPCPs") targeted to historically underserved borrowers and the support of locally-controlled SPCPs with a goal of lowering costs for such borrowers through lower than standard mortgage insurance requirements; and (2) Freddie Mac's Plan includes plans to work with mortgage insurers to look for ways to lower mortgage costs, the creation of SPCPs targeted to historically underserved borrowers, and the planned purchase of loans originated through lender-created SPCPs. To the extent the business practices and policies of the GSEs regarding mortgage insurance coverage, costs and cancellation change, including more broadly than through SPCPs, such changes may negatively impact the mortgage insurance industry.
 It is uncertain what role the GSEs, FHA and private capital, including private mortgage insurance, will play in the residential housing finance system in the future. The timing and impact on our business of any resulting changes is uncertain. Some changes would require Congressional action to implement and it is difficult to estimate when any action would be final and how long any associated phase-in period may last.
 The GSEs have private mortgage insurer eligibility requirements, or "PMIERs", for private mortgage insurers that insure loans delivered to or purchased by the GSEs. The financial requirements of the PMIERs require a mortgage insurer's Available Assets to equal or exceed its Minimum Required Assets. In August 2024, the GSEs issued updates to the calculation of Available Assets. The update will be implemented through a 24-month phased-in approach, with a fully effective date of September 30, 2026. MGIC is in compliance with the PMIERs and eligible to insure loans purchased by the GSEs, and does not expect the updated calculation of Available Assets to affect its compliance or eligibility status. In calculating Minimum Required Assets, MGIC receives significant credit for risk ceded under reinsurance transactions. See "Reinsurance" in this Item 1 for information about our reinsurance transactions and "Regulation – Direct Regulation" in this Item 1 for information about our compliance with the financial requirements of the PMIERs.
 The private mortgage insurance industry is greatly impacted by macroeconomic conditions that affect home loan originations and credit performance of home loans, including recession, unemployment rates, home prices, restrictions on mortgage credit due to underwriting standards, interest rates, household formations and homeownership rates. During the years leading up to the financial crisis of the 2000s, the mortgage lending industry increasingly made home loans with higher risk profiles. In certain sections of this Annual Report, we discuss our insurance written in 2005-2008 separately from our insurance written in earlier and later years. Beginning in 2007, job creation slowed and the housing markets began slowing in certain areas, with declines in certain other areas. In 2008 and 2009, employment in the U.S. decreased substantially and nearly all geographic areas in the U.S. experienced home price declines. Together, these conditions resulted in significant adverse developments for us and our industry. The operating environment for private mortgage insurers materially improved after the financial crisis, as the economy recovered.
 The COVID-19 pandemic had a material impact on our 2020 financial results. The increased level of unemployment and economic uncertainty resulted in an increase in our delinquency inventory for which we recorded increased loss reserves. Since that time, our mortgage delinquency inventory has decreased significantly and is below the levels seen immediately before the onset of the pandemic. The overall decline in the delinquency inventory, along with favorable loss reserve development in recent years has resulted in decreased losses incurred and increased net income.
 In 2024, $299 billion of mortgages were insured with primary coverage by private mortgage insurers, compared to $284 billion for the full year of 2023, and $405 billion for the full year of 2022. The high 2022 volume resulted, in part, from historically low interest rates driving sustained borrower demand, including for refinances, and the effect that the COVID-19 pandemic had on demand for homes.

 MGIC Investment Corporation 2024 Form 10-K | 9

 For most of our business, we and other private mortgage insurers compete directly with federal and state governmental and quasi-governmental agencies that sponsor government-backed mortgage insurance programs, principally the FHA, VA and USDA. The publication Inside Mortgage Finance estimates that in 2024, the FHA accounted for 33.5% of low down payment residential mortgages that were subject to FHA, VA, USDA or primary private mortgage insurance, compared to 33.2% in 2023 and 26.7% in 2022. Since 2012, the FHA's market share has been as low as 23.4% (2020) and as high as 42.1% (in 2012). Factors that influence the FHA's market share include relative rates and fees, underwriting guidelines and loan limits of the FHA, VA, private mortgage insurers and the GSEs; lenders' perceptions of legal risks under FHA versus GSE programs; flexibility for the FHA to establish new products as a result of federal legislation and programs; returns expected to be obtained by lenders for Ginnie Mae securitization of FHA-insured loans compared to those obtained from selling loans to the GSEs for securitization; and differences in policy terms, such as the ability of a borrower to cancel insurance coverage under certain circumstances. In 2023, the FHA announced a 30-basis point decrease in its mortgage insurance premium rates. This rate reduction has negatively impacted our NIW. We are unable to predict the extent of any further impact on our NIW or how the factors that affect the FHA's share of NIW will change in the future.
 Inside Mortgage Finance estimates that in 2024, the VA accounted for 24.5% of all low down payment residential mortgages that were subject to FHA, VA, USDA or primary private mortgage insurance, compared to 21.5% in 2023 and 24.5% in 2022. Since 2012, the VA's market share has been as high as 30.9% (in 2020). The VA's 2023 market share was the lowest since 2013 (22.8%). The VA program offers 100% LTV loans for qualifying borrowers.
 The private mortgage insurance industry also competes with alternatives to mortgage insurance, such as investors using risk mitigation and credit risk transfer techniques other than PMI, including capital market transactions entered into by the GSEs and banks; lenders and other investors holding mortgages in portfolio and self-insuring; and "piggyback loans," which combine a first lien loan with a second lien loan. In 2018, the GSEs initiated secondary mortgage market programs with loan level mortgage default coverage provided by various (re)insurers that are not mortgage insurers governed by PMIERs, and that are not selected by the lenders. While we view these programs as competing with traditional private mortgage insurance, we participate in them through an affiliate of MGIC.
 The GSEs (and other investors) have also used other forms of credit enhancement that did not involve traditional private mortgage insurance, such as engaging in credit-linked note transactions executed in the capital markets, and using other forms of debt issuances or securitizations that transfer credit risk directly to other investors, including competitors and an affiliate of MGIC; and using other risk mitigation techniques in conjunction with reduced levels of private mortgage insurance coverage.
 In addition to the FHA, VA, other governmental agencies and the alternatives to mortgage insurance discussed above, we compete with other mortgage insurers. The level of competition, including price competition, within the private mortgage insurance industry has remained intense over the past several years. See "Our Products and Services – Sales and Marketing and Competition – Competition" below for more information about the impact on our business of competition in the private mortgage insurance industry.
 In addition to being subject to the requirements and practices of the GSEs, private mortgage insurers are subject to comprehensive, detailed regulation by state insurance departments. The insurance laws of 16 jurisdictions, including Wisconsin, MGIC's domiciliary state, require a mortgage insurer to maintain a minimum amount of statutory capital relative to the RIF (or a similar measure) in order for the mortgage insurer to continue to write new business. Additionally, in 2023 a revised Mortgage Guaranty Insurance Model Act was adopted by the NAIC. The revised Model Act includes requirements relating to, among other things: (i) capital and minimum capital requirements, and contingency reserves; (ii) restrictions on mortgage insurers' investments in notes secured by mortgages; (iii) prudent underwriting standards and formal underwriting guidelines; (iv) the establishment of formal, internal "Mortgage Guaranty Quality Control Programs" with respect to in-force business; and (v) reinsurance and prohibitions on captive reinsurance arrangements. Wisconsin, where MGIC is domiciled, has begun the process to replace current mortgage insurance regulations with the Model Act, though it is expected that some changes will be made before formal adoption.

 B. Our Products and Services
 MORTGAGE INSURANCE
 In general, there are two principal types of private mortgage insurance: "primary" and "pool."
 Primary Insurance
 Primary insurance provides mortgage default protection on individual loans and covers a percentage of the unpaid loan principal, delinquent interest and certain expenses associated with the default and subsequent foreclosure on the mortgage or sale of the underlying property (collectively, the "claim amount"). In addition to the loan principal, the claim amount is affected by the mortgage note rate and the time necessary to complete the foreclosure or sale process. The insurer generally pays the coverage percentage of the claim amount specified in the primary policy but has the option to pay 100% of the claim amount and acquire title to the property. Primary insurance is generally written on first mortgage loans secured by owner occupied "single-family" homes, which are one-to-four family homes and condominiums. Primary insurance can be written on first liens secured by non-owner occupied single-family homes, which are referred to in the home mortgage lending industry as investor loans, and on vacation or second homes. Primary coverage can be used on any type of residential mortgage loan instrument approved by the mortgage insurer.

 References in this document to amounts of insurance written or in force, risk written or risk in force, and other historical data related to our insurance refer only to direct (before giving effect to reinsurance) primary insurance, unless otherwise indicated. Primary insurance may be written on a flow basis, in which loans are insured in individual, loan-by-loan transactions, or may be written on a bulk basis, in which each loan in a portfolio of loans is individually insured in a single, bulk transaction. Our new primary insurance written was $55.7 billion in 2024, compared to $46.1 billion in 2023 and $76.4 billion in 2022. The increase in 2024 compared to 2023 reflects an increase in refinance volumes, attributed to a brief decline in interest rates during 2024, while purchase origination activity remained relatively flat.
 The following charts show, on a direct basis, our primary IIF and primary RIF as of December 31 for the years indicated.

 For loans sold to a GSE, the coverage percentage must comply with the requirements established by the particular GSE to which the loan is delivered. The GSEs have different loan purchase programs that allow different levels of mortgage insurance coverage. Under the "charter coverage" program, on certain loans lenders may choose a mortgage insurance coverage percentage that is less than the GSEs' "standard coverage" and only the minimum required by the GSEs' charters, with the GSEs paying a lower price for such loans. In 2024, a substantial majority of our volume was on loans with GSE standard or higher coverage.
 For loans that are not sold to the GSEs, the lender determines the coverage percentage from those that we offer. Higher coverage percentages generally result in increased severity, which is the amount paid on a claim. We charge higher premium rates for higher coverage percentages. However, there can be no assurance that the higher premium rates adequately reflect the risks associated with higher coverage percentages. In accordance with GAAP for the mortgage insurance industry, loss reserves are only established for policies covering delinquent loans. Historically, because relatively few delinquencies occur in the early years of a book of business, the higher premium revenue from higher coverage has been recognized before any significant higher losses resulting from that higher coverage may be incurred. For more information, see "Exposure to Catastrophic Loss; Delinquencies; Claims; Loss Mitigation."
 In general, mortgage insurance coverage cannot be terminated by the insurer. However, subject to certain restrictions on our rescission rights as specified in our insurance policy, we may terminate or rescind coverage for, among other reasons, non-payment of premium, certain material misrepresentations and fraud in connection with the application for the insurance policy. Mortgage insurance coverage under monthly or annual premium plans are renewable at the option of the insured lender, at the renewal rate fixed when the loan was initially insured. Lenders may cancel insurance written on a flow basis at any time at their option or because of mortgage repayment, which may be accelerated because of the refinancing of mortgages.
 In the case of a loan purchased by a GSE, a borrower may request termination of insurance based on the home's current value if certain LTV ratio and seasoning requirements are met and the borrowers have an acceptable payment history. For loans seasoned between two and five years, the LTV ratio must be 75% or less, and for loans seasoned more than five years the LTV ratio must be 80% or less. If the borrower has made substantial improvements to the property, the GSEs allow for cancellation once the LTV ratio reaches 80% or less with no minimum seasoning requirement.
 Mortgage insurance for loans secured by one-family, primary residences can be canceled under HOPA. In general, HOPA requires a servicer to cancel the mortgage insurance if a borrower requests cancellation when the principal balance of the loan is first scheduled to reach 80% of the original value of the property, or reaches that percentage through payments, if 1) the borrower is current on the loan and has a "good payment history" (as defined by HOPA), 2) if required by the mortgage owner, the borrower provides evidence that the value of the property has not declined below the original value, and 3) if required by the mortgage owner, the borrower certifies that the borrower's equity in the property is not subject to a subordinate lien. Additionally, HOPA requires mortgage insurance to terminate

 MGIC Investment Corporation 2024 Form 10-K | 11

 automatically when the principal balance of the loan is first scheduled to reach 78% of the original value of the property and the borrower is current on loan payments or thereafter becomes current. Annually, servicers must inform borrowers of their right to cancel or terminate mortgage insurance. The provisions of HOPA described above apply only to borrower paid mortgage insurance, which is described below.
 Coverage tends to continue for borrowers experiencing economic difficulties or living in areas experiencing home price depreciation. The persistency of coverage for those borrowers, coupled with cancellation of coverage for other borrowers, can increase the percentage of an insurer's portfolio covering loans with more credit risk. This development can also occur during periods of heavy mortgage refinancing because borrowers experiencing property value appreciation are less likely to require mortgage insurance at the time of refinancing, while borrowers not experiencing property value appreciation are more likely to continue to require mortgage insurance at the time of refinancing or not qualify for refinancing at all (including if they have experienced economic difficulties) and thus remain subject to the mortgage insurance coverage.
 The percentage of NIW on loans representing refinances was 4% for 2024, compared to 2% for 2023 and 3% for 2022. When a borrower refinances a mortgage loan insured by us by paying it off in full with the proceeds of a new mortgage that is also insured by us, the insurance on that existing mortgage is cancelled, and insurance on the new mortgage is considered to be NIW. Therefore, continuation of our coverage from a refinanced loan to a new loan results in both a cancellation of insurance and NIW. When a lender and borrower modify a loan rather than replace it with a new one or enter into a new loan pursuant to a loan modification program, our insurance continues without being cancelled, assuming that we consent to the modification or new loan. As a result, such modifications or new loans are not included in our NIW.
 In addition to varying with the coverage percentage, our premium rates for insurance have varied depending upon the perceived risk of a claim on the insured loan and thus have taken into account, among other things, the LTV ratio, the borrower's credit score and DTI ratio, the number of borrowers, the property location, the mortgage term and whether the property is the borrower's primary residence. In recent years, the mortgage insurance industry has materially reduced its use of standard rate cards, which were fairly consistent among competitors, and correspondingly increased its use of (i)"risk based pricing systems" that use a spectrum of filed rates to allow for formulaic, risk-based pricing based on multiple attributes that may be quickly adjusted within certain parameters, and (ii) customized rate plans pursuant to which rates may be available to customers for a defined period of time.

 The borrower's mortgage loan instrument may require the borrower to pay the mortgage insurance premium. Our industry refers to the related mortgage insurance as "borrower-paid" or BPMI. If the borrower is not required to pay the premium and mortgage insurance is required in connection with the origination of the loan, then the premium is paid by the lender, who may recover the premium through an increase in the note rate on the mortgage or higher origination fees. Our industry refers to the related mortgage insurance as "lender-paid" or LPMI. Most of our primary IIF is BPMI.
 There are several payment plans available to the borrower, or lender, as the case may be. Under the single premium plan, the borrower or lender pays us in advance a single payment covering a specified term exceeding twelve months. Under the monthly premium plan, the borrower or lender pays us a monthly premium payment to provide only one month of coverage. Under the annual premium plan, an annual premium is paid to us in advance, with annual renewal premiums paid in advance thereafter.
 During 2024, 2023 and 2022, the single premium plan represented approximately 2%, 4% and 4%, respectively, of our NIW. The monthly premium plan represented approximately 98%, 96% and 96%, respectively. The annual premium plan represented less than 1% of NIW in each of those years. Depending upon the actual life of a single premium policy and its premium rate relative to that of a monthly premium policy, a single premium policy may generate more or less premium than a monthly premium policy over its life.
 CRT and Pool Insurance
 In connection with the GSEs' credit risk transfer programs, we provide insurance and reinsurance covering portions of the credit risk related to certain reference pools of mortgages acquired by the GSEs. The amount of risk associated with these transactions was approximately $392 million and $310 million as of December 31, 2024 and December 31, 2023, respectively.
 We have written no new pool insurance since 2008; however, we may write pool risk in the future. As of December 31, 2024, our direct pool RIF was $226 million ($177 million on pool policies with aggregate loss limits and $49 million on pool policies without aggregate loss limits), compared to $256 million ($186 million on pool policies with aggregate loss limits and $70 million on pool policies without aggregate loss limits) at December 31, 2023.

 (1)Includes fixed rate mortgages with temporary buydowns (where in effect, the applicable interest rate is typically reduced by one or two percentage points during the first two years of the loan and then increased thereafter to the original interest rate), ARMs in which the initial interest rate is fixed for at least five years, and balloon payment mortgages (a loan with a maturity, typically five to seven years, that is shorter than the loan's amortization period).
 (2)Includes ARMs where payments adjust fully with interest rate adjustments. Also includes pay option ARMs and other ARMs with negative amortization features, which collectively at each of December 31, 2024 and 2023, represented 0.1% of primary RIF. As indicated in note (1), does not include ARMs in which the initial interest rate is fixed for at least five years. For both December 31, 2024 and 2023, ARMs with LTV ratios in excess of 90% represented 0.1%, of primary RIF, respectively.
 (3)Loans within the conforming loan limit have an original principal balance that does not exceed the maximum original principal balance of loans that the GSEs will purchase. The conforming loan limit for one unit properties was $726,200 for 2023, $766,550 for 2024, and is $806,500 for 2025. The limit for high cost communities has been higher and was $1,149,825 in 2024 compared with $1,209,750 for 2025. Non-conforming loans are loans with an original principal balance above the conforming loan limit.
 (4)Includes cooperatives and manufactured homes deemed to be real estate.
 (5)Reduced documentation loans were originated prior to 2009 under programs in which there was a reduced level of verification or disclosure compared to traditional mortgage loan underwriting, including programs in which the borrower's income and/or assets were disclosed in the loan application but there was no verification of those disclosures ("stated" documentation) and programs in which there was no disclosure of income or assets in the loan application ("no" documentation). In accordance with industry practice, loans approved by GSE and other automated underwriting (AU) systems under "doc waiver" programs that did not require verification of borrower income are classified by us as "full documentation." We understand that the GSEs terminated their "doc waiver" programs in the second half of 2008.
 (6)Represents the FICO score at loan origination. The weighted average "decision FICO score" at loan origination for NIW in 2024 was 747 compared to 753 in 2023. The FICO score for a loan with multiple borrowers is the lowest of the borrowers' decision FICO scores. A borrower's "decision FICO score" is determined as follows: if there are three FICO scores available, the middle FICO score is used; if two FICO scores are available, the lower of the two is used; if only one FICO score is available, it is used. A FICO score is a score based on a borrower's credit history generated by a model developed by Fair Isaac Corporation.

 OTHER PRODUCTS AND SERVICES
 Contract Underwriting
 A non-insurance subsidiary of ours provides contract underwriting services for lenders, pursuant to which loans are underwritten to conform to prescribed guidelines. The guidelines might be the lender's own guidelines or the guidelines of Fannie Mae, Freddie Mac or a non-GSE investor. These services are provided for loans that require private mortgage insurance as well as for loans that do not require private mortgage insurance.

 CUSTOMERS
 Originators of residential mortgage loans such as savings institutions, commercial banks, mortgage brokers, credit unions, mortgage bankers and other lenders have historically determined the placement of mortgage insurance written and as a result are our customers. To obtain primary insurance from us, a mortgage lender must first apply for and receive a mortgage guaranty master policy from us. Our top 10 customers generated 37% of our NIW in both 2024 and 2023. Our relationships with our customers could be adversely affected by a variety of factors, including if our premium rates are higher than those of our competitors, our underwriting requirements are more restrictive than those of our competitors, or our customers are dissatisfied with our claims-paying practices (including insurance policy rescissions and claim curtailments). Information about some of the other factors that can affect a mortgage insurer's relationship with its customers can be found in our risk factor titled "Competition or changes in our relationships with our customers could reduce our revenues, reduce our premium yields and/or increase our losses" in Item 1A.

 MGIC Investment Corporation 2024 Form 10-K | 15

 SALES AND MARKETING AND COMPETITION
 Sales and Marketing
 Our employees sell our insurance products throughout the United States, Puerto Rico, and Guam.

 Competition
 Our competition includes other mortgage insurers, governmental agencies and products designed to eliminate the need to purchase private mortgage insurance. We and other private mortgage insurers compete directly with federal and state government and quasi-governmental agencies, principally the FHA and the VA. The FHA, VA and USDA sponsor government-backed mortgage insurance programs, and it is estimated that during 2024, they accounted for a combined approximately 58.9% of the total low down payment residential mortgages which were subject to FHA, VA, USDA or primary private mortgage insurance, compared to 55.9% in 2023. For more information about the market share of the FHA and the VA, see "Overview of the Private Mortgage Insurance Industry and its Operating Environment" above.

 The PMI industry is highly competitive. We believe that we currently compete with other private mortgage insurers based on premium rates, underwriting requirements, financial strength (including based on credit or financial strength ratings), customer relationships, name recognition, reputation, strength of management teams and field organizations, and the effective use of technology and innovation in the delivery and servicing of our mortgage insurance products.
 The U.S. PMI industry currently consists of six active mortgage insurers and their affiliates, including MGIC. Our market share (as measured by NIW) was 18.6% in 2024, compared to 16.3% in 2023. (source: Inside Mortgage Finance).
 If we are unable to compete effectively in the current or any future markets as a result of the financial strength ratings assigned to our insurance subsidiaries, our future new insurance written could be negatively affected. Our ability to participate in the non-GSE residential mortgage-backed securities market (the size of which has been limited since 2008, but may grow in the future), could depend on our ability to maintain and improve our investment grade ratings for our insurance subsidiaries. Although the current PMIERs of each of the GSEs do not require an insurer to maintain minimum financial strength ratings, the GSEs consider financial strength ratings to be important when using forms of credit enhancement other than traditional mortgage insurance.

 In assigning financial strength ratings, in addition to considering the adequacy of the mortgage insurer's capital to withstand very high claim scenarios under assumptions determined by the rating agency, we believe rating agencies review a mortgage insurer's historical and projected operating performance, franchise risk, business outlook, competitive position, management, corporate strategy, enterprise risk management and other factors. The rating agency issuing the financial strength rating can withdraw or change its rating at any time. At the time that this annual report was finalized, the financial strength of MGIC was rated A (with a stable outlook) by A.M. Best, A3 (with a positive outlook) by Moody's Investors Service and A- (with a stable outlook) by Standard & Poor's Global Ratings.

 C. Risk Management
 ENTERPRISE RISK MANAGEMENT
 The Company has an enterprise risk management ("ERM") framework that it believes is commensurate with the size, nature and complexity of the Company's business activities (all of which relate to insuring or reinsuring mortgage credit risk) and strategies. Among the key objectives of the ERM framework are to have a clear and well documented shared understanding, by senior management and the Board, of the Company's risk management philosophy and overall appetite for risk, and that there are appropriate monitoring, management and reporting mechanisms to support the framework.
 Risk Governance
 The Company maintains a Senior Management Oversight Committee ("SMOC") that, at the management level, serves as its primary business, operations, strategy, and risk management oversight committee. SMOC is the senior-most committee of management leadership and oversees the identification and governance of key risks and oversees the Company's ERM framework. SMOC manages the risks associated with strategic and business issues critical to the Company, such as those related to credit policy, the characteristics of the Company's new insurance and insurance in force, existing and proposed new regulation, product pricing, and capital structure. Relating specifically to ERM, SMOC oversees development and implementation of the Company's ERM framework, including the identification and governance of key risks, and monitoring of the Company's risk profile as it relates to those key risks. SMOC is chaired by the Company's Chief Executive Officer. Other members are the Company's President and Chief Operating Officer, General Counsel, and Chief Financial and Risk Officer, who is the principal management liaison to the Risk Management Committee. SMOC also has sub-committees to assist in the effective discharge of its responsibilities for oversight and management of specific risk. These sub-committees create additional transparency across the major types of risk the Company manages, increase communication and collaboration, and develop talent.

 The Board implements its risk oversight function as a whole and through delegation to its Committees which meet regularly and report back to the full Board. The Risk Management Committee coordinates with the Board and other Board Committees regarding the assignment to the Board and Committees of oversight responsibilities for risks considered to have the greatest potential to materially

 MGIC Investment Corporation 2024 Form 10-K | 16

 impact the Company's ability to accomplish its strategic goals. Each Committee's charter describes its principal responsibilities, including its oversight responsibility for applicable key risks.
 Corporate Sustainability Risk Governance
 The Company maintains a Corporate Sustainability Executive Council that, at the management level, supports the Company's on-going commitment to environmental, health and safety, corporate social responsibility, corporate governance, sustainability, and other public policy matters relevant to the Company. In performing this general responsibility, the Council has discretion to: adopt the Company's general strategy with respect to sustainability matters; identify current and emerging sustainability issues that may affect the Company's business, strategy, operations, performance, or public image; make recommendations regarding policies, practices, procedures, or disclosures to address sustainability matters; oversee the Company's corporate sustainability and related disclosures surrounding sustainability matters; and advise on material concerns of shareholders or stakeholders regarding sustainability matters.

 The Board has delegated oversight for the following sustainability matters to the following committees, who regularly report their actions to the Board:
 • Risk Management Committee: Mortgage Credit Risk, including risks associated with climate change.
 • Management Development, Nominating and Governance Committee: Corporate governance and human capital management policies such as executive compensation; succession planning; recruitment, management recruitment, retention, training and development; workforce planning, recruitment, morale and talent; diversity and inclusion initiatives; and work environment, including health and safety.
 • Securities Investment Committee: Our investment portfolio; such oversight may include consideration of sustainability factors.
 • Audit Committee: Disclosure controls and procedures relating to financial reports made to the SEC and corporate sustainability reports.
 • Business Transformation and Technology Committee: Cybersecurity and business continuity.
 Risk Management and Controls
 The Company has established enterprise-wide policies, procedures and processes to allow it to identify, assess, monitor and manage the Company's various risks. Management of these risks is an interdepartmental endeavor, with oversight by the Chief Financial Officer and Chief Risk Officer, and the SMOC. The Company's Internal Audit function, which reports to the Audit Committee of the Board of Directors, provides independent ongoing assessments of the Company's management of certain enterprise risks and reports its findings to the Audit Committee.

 Risk Identification and Assessment
 On a regular basis, the Company monitors key risks with a focus on identifying risks or changes to risks with the greatest impact on the Company's ability to accomplish its strategic goals. In addition to the ongoing monitoring, the Company also identifies key risks in a bottom up process facilitated through questionnaires and discussions during an annual compliance and risk forum with co-workers across a number of business functions. The results of the identification process are presented to the Board's Audit Committee.

 Risk Reporting and Communication The Company's Risk Management and Finance departments produce various analyses, reports and key risk indicators ("KRIs") that are reported to the SMOC, the Risk Management Committee and the Board quarterly. For our largest risk exposure, mortgage credit risk, these KRIs include risk factors for the Company's NIW, IIF, quality control and claim activity, and the quarterly reports include performance relative to metrics and thresholds. Each of the other Board Committees also receive regular reporting concerning the risks they oversee.

 Although the Company has in place the ERM framework discussed above, it may not be effective in identifying, or adequate in controlling or mitigating, the risks we face. For more information, see our risk factor titled "If our risk management programs are not effective in identifying, or adequate in controlling or mitigating, the risks we face, or if the models used in our businesses are inaccurate, it could have a material adverse impact on our business, results of operations and financial condition" in Item 1A.
 MORTGAGE CREDIT RISK
 We believe that mortgage credit risk is materially affected by:

 • the condition of the economy, including the direction of change in home prices and employment, in the area in which the property is located;
 • the borrower's credit profile, including the borrower's credit history, DTI ratio and cash reserves, and the willingness of a borrower with sufficient resources to make mortgage payments when the mortgage balance exceeds the value of the home;
 • the loan product, which encompasses the LTV ratio, the type of loan instrument, including whether the instrument provides for fixed or variable payments and the amortization schedule, the type of property (including its use) and the purpose of the loan;
 • origination practices of lenders and the percentage of coverage on insured loans; and

 MGIC Investment Corporation 2024 Form 10-K | 17

 • the size of insured loans.

 We believe that, excluding other factors, claim incidence increases:

 • during periods of economic contraction and home price depreciation, including when these conditions may not be nationwide, compared to periods of economic expansion and home price appreciation;
 • for loans to borrowers with lower FICO scores compared to loans to borrowers with higher FICO scores;
 • for loans to borrowers with higher DTI ratios compared to loans to borrowers with lower DTI ratios;
 • for loans with less than full underwriting documentation compared to loans with full underwriting documentation;
 • for loans with higher LTV ratios compared to loans with lower LTV ratios;
 • for variable payment loans when the reset interest rate significantly exceeds the interest rate at the time of loan origination;
 • for loans that permit the deferral of principal amortization compared to loans that require principal amortization with each monthly payment;
 • for loans for which the subject property will be an investment property or second home as opposed to a borrower's primary residence; and

 • for cash out refinance loans compared to rate and term refinance loans.

 Other types of loan characteristics relating to the individual loan or borrower may also affect the risk potential for a loan. The presence of a number of higher-risk characteristics in a loan materially increases the likelihood of a claim on such a loan unless there are other characteristics to mitigate the risk.

 We charge higher premium rates to reflect the increased risk of claim incidence that we perceive is associated with a loan. Not all higher risk characteristics are reflected in our premium rates; however, in 2019 we introduced MiQ, our risk-based pricing system that establishes our premium rates based on more risk attributes than were previously considered. There can be no assurance that our premium rates adequately reflect the increased risk, particularly in a period of economic recession, high unemployment, slowing home price appreciation or home price declines, or when extraordinary events occur, such as pandemics, wars, periods of extreme inflation, or environmental disasters related to changing climactic conditions. For additional information, see our risk factors in Item 1A, including the one titled "The premiums we charge may not be adequate to compensate us for our liabilities for losses and as a result any inadequacy could materially affect our financial condition and results of operations."

 Underwriting Insurance Applications
 Applications for mortgage insurance are submitted to us through both our delegated and non-delegated submission options. Under the delegated option, applications are submitted to us electronically and we rely upon the lender's representations and warranties that the data submitted is true, accurate and consistent with the documents in the lender's loan origination file, when making our insurance decision. Non-delegated applications are submitted with documents from the lender's loan origination file. Regardless of the submission option, we apply our underwriting requirements and premium rate plans to determine coverage eligibility and the premium rate. If the loan is eligible for coverage, we will issue a commitment to insure the loan.

 Beginning in 2013, we aligned most of our underwriting requirements with Fannie Mae and Freddie Mac for loans that receive and are processed in accordance with certain approval recommendations from a GSE automated underwriting system. Our underwriting requirements are available on our website at  We may approve loans that do not meet all of our underwriting requirements under certain circumstances.

 Exposure to Catastrophic Losses
 The PMI industry experienced catastrophic losses in the mid-to-late 1980s, similar to the losses we experienced in 2007-2013. For background information about such losses in 2007-2013, as well as information about the effects of the COVID-19 pandemic, refer to "General – Overview of Private Mortgage Insurance Industry and its Operating Environment" above.

 Delinquencies
 The claim cycle on PMI generally begins with the insurer's receipt of notification of a delinquency on an insured loan from the loan servicer. For reporting purposes, a loan is generally considered to be delinquent when it is two or more payments past due. Most servicers report delinquent loans to us within this two month period. The incidence of delinquency is affected by, both macroeconomic conditions (e.g. unemployment rates, income growth rates, a decrease in home prices, etc.) and individual borrower situations (e.g. family status, health issues, income loss, credit worthiness, etc.) Delinquencies that are not cured result in a claim to us. See "– Claims." Delinquencies may be cured by the borrower bringing current the delinquent loan payments or by a sale of the property and the satisfaction of all amounts due under the mortgage. In addition, when a policy is rescinded or a claim is denied we remove the loan from our delinquency inventory.

 Note: Asterisk denotes jurisdictions in the table above that predominately use a judicial foreclosure process, which generally increases the amount of time it takes for a foreclosure to be completed.

 The primary delinquency inventory in those same jurisdictions at December 31, 2024 and 2023 appears in "Management's Discussion and Analysis – Consolidated Results of Operations – Losses and expenses – Loss Reserves," in Item 7.

 Claims
 Claims result from delinquencies that are not cured. Whether a claim results from an uncured delinquency depends, in large part, on the willingness and ability of the borrower and lender to enter into a loan modification that provides for a cure of the delinquency and the borrower's or the lender's ability to sell the home for an amount sufficient to satisfy all amounts due under the mortgage. Various factors affect the frequency and amount of claims, including local home prices, employment levels, and interest rates. If a delinquency results in a paid claim, any renewal premiums collected to insure the loan for the time period following the last paid installment is returned to the servicer along with the claim payment.

 Under the terms of our master policy, the lender is required to file a claim for primary insurance with us within 60 days after it has acquired title to the underlying property (typically through foreclosure). Generally, the longer the period between delinquency and claim filing, the greater the size of the claim, or "severity." It is difficult to estimate how long it may take for current and future delinquencies that do not cure to develop into paid claims.

 The majority of loans we insured prior to 2014 (which represent 29% of the loans in the delinquency inventory) are covered by master policy terms that, except under certain circumstances, do not limit the number of years of accumulated interest that an insured may include in a claim. Under our current master policy terms, an insured can include accumulated interest only for the first three years the loan is delinquent.

 MGIC Investment Corporation 2024 Form 10-K | 19

Other determinants of claim severity are the amount of the mortgage loan, the coverage percentage on the loan, loss mitigation efforts, and local market conditions. For information about our primary average claim paid, see "Management's Discussion and Analysis – Consolidated Results of Operations – Net Losses and LAE Paid," in Item 7.

 Within 60 days after a claim has been filed and all documents required to be submitted to us have been delivered, we generally have the option to either (1) pay the coverage percentage specified for the insured loan, with the insured retaining title to the underlying property and receiving all proceeds from the eventual sale of the property, (2) pay the loss on the sale of the property if it has already been sold (calculated by subtracting the sale proceeds from the claim amount) or (3) pay 100% of the claim amount in exchange for conveyance to us of good and marketable title to the property. After we receive title to a property, we sell it for our own account. If we fail to pay a claim timely, we are subject to additional interest expense.

 Claim activity is not evenly spread throughout the coverage period of a book of primary business. Claims received are generally lower during the first two years following issuance of coverage on a loan. The highest level of claim activity has typically occurred in the third and fourth years after the year of loan origination. Thereafter, the number of claims received has typically declined at a gradual rate, although the rate of decline can be affected by conditions in the economy, including slowing home price appreciation or home price depreciation. Moreover, when a loan is refinanced, because the new loan replaces, and is a continuation of, an earlier loan, the pattern of claims frequency for that new loan may be different from the typical pattern for other loans. Persistency, the condition of the economy, including unemployment, and other factors can affect the pattern of claim activity. For example, a weak economy can lead to claims from older books of business increasing, continuing at stable levels or experiencing a lower rate of decline. As of December 31, 2024, 50% of our primary RIF was written subsequent to December 31, 2021, 74% of our primary RIF was written subsequent to December 31, 2020, and 87% of our primary RIF was written subsequent to December 31, 2019. See "Our Products and Services – Mortgage Insurance – Primary Insurance In Force and Risk In Force by Policy Year" above.

 Loss Mitigation
 Before paying a claim, generally we review the loan and servicing files to determine the appropriateness of the claim amount. Our insurance policies generally provide that we can reduce or deny a claim if the servicer did not comply with its obligations under our insurance policy, including the requirement to mitigate our loss by performing reasonable loss mitigation efforts or, for example, diligently pursuing a foreclosure or bankruptcy relief in a timely manner. We call such reduction of claims submitted to us "curtailments." In each of 2024 and 2023, curtailments reduced our average claim paid by approximately 4.7% and 5.4%, respectively.

 When reviewing the loan file associated with a claim, we may determine that we have the right to rescind coverage on the loan. In our SEC reports, we refer to insurance rescissions and denials of claims as "rescissions" and variations of this term. The circumstances in which we are entitled to rescind coverage narrowed under more restrictive policy terms beginning in 2012. As a result of revised PMIERs requirements, we have revised our master policy effective for new insurance written beginning March 1, 2020. Our ability to rescind insurance coverage has become further limited for insurance we write under the new master policy, potentially resulting in higher losses than would be the case under our previous master policies. In recent years, an immaterial percentage of claims received in a quarter have been resolved by rescissions. We do not expect future rescissions will be a significant portion of the claims we resolve over the next few years.

 Our loss reserving methodology incorporates our estimates of future rescissions, curtailments, and reversals of rescissions and curtailments. When we rescind coverage, we return all premiums previously paid to us under the policy and are relieved of our obligation to pay a claim under the policy. A variance between ultimate actual rescission, curtailment or reversal rates and our estimates, as a result of the outcome of litigation, settlements or other factors, could materially affect our losses.

 When the insured disputes our right to rescind coverage or curtail a claim, we generally engage in discussions in an attempt to settle the dispute. If we are unable to reach a settlement, the outcome of a dispute ultimately may be determined by legal proceedings. Under ASC 450-20, until a loss associated with settlement discussions or legal proceedings becomes probable and can be reasonably estimated, we do not accrue an estimated loss. When we determine that a loss is probable and can be reasonably estimated, we record our best estimate of our probable loss.

 Loss Reserves
 A significant period of time typically elapses between the time when a borrower becomes delinquent on a mortgage payment, which is the event triggering a potential future claim payment by us, the reporting of the delinquency to us, the acquisition of the property by the lender (typically through foreclosure) or the sale of the property, and the eventual payment of the claim related to the uncured delinquency or a rescission. To recognize the estimated liability for losses related to outstanding reported delinquencies, we establish loss reserves by estimating the number of loans in our delinquency inventory that will result in a claim payment, which is referred to as the claim rate, and further estimating the amount of the claim payment, which is referred to as claim severity. Our loss reserve estimates are established primarily based upon historical experience, including rescission and curtailment activity. In accordance with GAAP for the mortgage insurance industry, we generally do not establish case reserves for future claims on insured loans that are not currently delinquent.

 MGIC Investment Corporation 2024 Form 10-K | 20

 We also establish reserves to provide for the estimated costs of settling claims, general expenses of administering the claims settlement process, legal fees and other fees ("loss adjustment expenses"), and for losses and loss adjustment expenses from delinquencies that have occurred, but have not yet been reported to us (IBNR).

 Our reserving process bases our estimates of future events on our past experience. For further information about our loss reserving methodology, refer to "Management's Discussion and Analysis – Critical Accounting Estimates," in Item 7. Estimation of loss reserves is inherently judgmental and conditions that have affected the development of the loss reserves in the past may not necessarily affect development patterns in the future, in either a similar manner or to a similar degree. For further information, see our risk factors in Item 1A, including the ones titled "Because we establish loss reserves only upon a loan delinquency rather than based on estimates of our ultimate losses on risk in force, losses may have a disproportionate adverse effect on our earnings in certain periods," and "Because loss reserve estimates are subject to uncertainties, paid claims may be substantially different than our loss reserves."

 Our losses incurred were $(14.9) million in 2024, compared to $(20.9) million and $(254.6) million in 2023 and 2022, respectively. For information about losses incurred from 2022 to 2024, including the amounts of losses incurred that are associated with delinquency notices received in the reporting year compared to losses incurred associated with delinquency notices received in prior years, see Note 8 – "Loss Reserves" to our consolidated financial statements in Item 8.

 D. Reinsurance Agreements
 We have in place quota share reinsurance ("QSR") and excess of loss reinsurance ("XOL") transactions providing various amounts of coverage on our risk in force as of December 31, 2024. These transactions allow us to better manage our risk profile, because they reduce the amount of capital we are required to hold to comply with insurance regulatory requirements and the requirements of the GSEs' PMIERs. Our reinsurance strategy focuses on reinsuring our most recent or future NIW, while recapturing risk on attractive seasoned vintages.

 QUOTA SHARE TRANSACTIONS
 Our QSR Transactions are with unaffiliated reinsurers. As of December 31, 2024, our QSR transactions cover most of our insurance written from 2021 through 2024, and a smaller percentage of our insurance written from 2025. The weighted average coverage percentage of our QSR transactions was 32.0%, based on risk in force as of December 31, 2024.

 At December 31, 2024 and 2023, approximately 68.2% and 60.4%, respectively, of our IIF was subject to quota share reinsurance transactions. In 2024 and 2023, approximately 86.9% and 86.8%, respectively, of our NIW was subject to QSR transactions.

 The structure of the QSR transactions is a quota share of various percentages of the policies covered, with a ceding commission and a profit commission. The profit commission under our QSR Transactions also varies inversely with the level of ceded losses incurred on a "dollar for dollar" basis and can be eliminated at ceded loss levels higher than what we have experienced on our QSR Transactions.

 EXCESS OF LOSS TRANSACTIONS
 We have XOL transactions with a panel of unaffiliated reinsurers executed through the traditional reinsurance market ("Traditional XOL") and with unaffiliated special purpose insurers ("Home Re") transactions. Our Home Re transactions issued notes linked to the reinsurance coverage ("Insurance Linked Notes" or "ILNs"). Our XOL transactions provide XOL reinsurance coverage for a portion of the risk associated with certain mortgage insurance policies having insurance coverage in force dates from August 1, 2020 through December 31, 2024.

 For the reinsurance coverage periods, we retain the first layer of the respective aggregate losses, and the reinsurers will then provide second layer coverage up to the outstanding reinsurance coverage amount. We retain losses in excess of the outstanding reinsurance coverage amount. The aggregate XOL reinsurance coverage decreases over a period of either 10 of 12.5 years, depending on the transaction, subject to certain conditions, as the underlying covered mortgages amortize or are repaid, or mortgage insurance losses are paid.

 The Home Re Entities financed the coverages with the proceeds of the ILNs in an aggregate amount equal to the initial reinsurance coverage amounts. Each ILN is non-recourse to any of our assets. The proceeds of the ILNs, which were deposited into reinsurance trusts for our benefit, will be the source of reinsurance claim payments to us and principal repayments on the ILNs.
 Although reinsuring against possible loan losses does not discharge us from liability to a policyholder, it reduces the amount of capital we are required to retain against potential future losses for PMIERs, rating agency and insurance regulatory purposes. The calculated credit for XOL reinsurance transactions under PMIERs is generally based on the PMIERs requirement of the covered loans and the attachment and detachment point of the coverage, all of which fluctuate over time. PMIERs credit is generally not given for the reinsured risk above the PMIERs requirement. The GSEs have discretion to further limit reinsurance credit under the PMIERs. The total credit for risk ceded under our reinsurance transactions is subject to periodic review by the GSEs.

 MGIC Investment Corporation 2024 Form 10-K | 21

 For further information about our reinsurance agreements, including the Company's early termination rights, see Note 9 – "Reinsurance," to our consolidated financial statements in Item 8, and our risk factor titled "Reinsurance may be unavailable at current levels and prices, and/or the GSEs may reduce the amount of capital credit we receive for our reinsurance transactions" in Item 1A.

 E. Investment Portfolio
 POLICY AND STRATEGY
 At December 31, 2024, the fair value of our investment portfolio was approximately $5.9 billion. In addition, at December 31, 2024, our total assets included approximately $229 million of cash and cash equivalents. At December 31, 2024, approximately $1.1 billion of investments and cash and cash equivalents was held by our parent company, and the remainder was held by our subsidiaries, primarily MGIC.

 As of December 31, 2024, approximately 94% of our investment portfolio (excluding cash and cash equivalents) was managed by two external investment managers, although we maintain overall control of investment policy and strategy. We maintain direct management of the remainder of our investment portfolio. Unless otherwise indicated, the remainder of the discussion regarding our investment portfolio refers to our investment portfolio only and not to cash and cash equivalents.

 Our management is responsible for the execution of our investment strategy and compliance with the adopted investment policies, and review of investment performance and strategy with the Securities Investment Committee of the Board of Directors on a quarterly basis.

 Our current strategy for the investment portfolio emphasizes the following: preservation of PMIERs assets, limiting portfolio volatility, maximizing total return with an emphasis on yield, and providing sufficient liquidity with minimal realized losses to meet expected and unexpected obligations. Consequently, our investment portfolio consists almost entirely of high-quality, investment grade, fixed income securities. Our investment portfolio strategy considers tax efficiency. The mix of tax-exempt municipal securities in our investment portfolio will be dependent upon their value, relative to taxable equivalent securities, determined in part by federal statutory tax rates. Our investment policies and strategies are subject to change depending upon regulatory, economic and market conditions and our existing or anticipated financial condition and operating requirements.

 For information about the credit ratings of securities in our investment portfolio, see "Balance Sheet Review" in Item 7.

 We have no derivative financial instruments in our investment portfolio. Securities with stated maturities due within up to one year, after one year and up to five years, after five years and up to ten years, and after ten years, represented 12%, 28%, 28%, and 15%, respectively, of the total fair value of our fixed income investment securities. Asset-backed and mortgage-backed securities are not included in these maturity categories as the expected maturities may be different from the stated maturities depending upon the periodic payments during the life of the security. Asset-backed securities represent 10% of the investment portfolio (CLOs represent 3%, CMBS represent 4% and other asset-backed securities represent 3%). GNMA and other agency mortgage-backed securities represent 6% of the investment portfolio. Our pre-tax yield was 4.0%, 3.7%, and 3.0% for 2024, 2023, and 2022, respectively, and our after-tax yield was 3.2%, 3.0%, and 2.5% for 2024, 2023, and 2022, respectively.

 F. Regulation
 DIRECT REGULATION
 We are subject to comprehensive, detailed regulation by state insurance departments. These regulations are principally designed for the protection of our insured policyholders, rather than for the benefit of investors. Although their scope varies, state insurance laws generally grant broad supervisory powers to agencies or officials to examine insurance companies and enforce rules or exercise discretion affecting almost every significant aspect of the insurance business.

 In general, regulation of our subsidiaries' businesses relates to:
 • minimum capital levels and adequacy ratios;
 • requirements regarding contingency reserves;
 • premium rates and discrimination in pricing;
 • licenses to transact businesses;
 • policy forms;
 • insurable loans;
 • annual and other reports on financial condition;
 • the basis upon which assets and liabilities must be stated;
 • reinsurance requirements;
 • limitations on the types of investment instruments which may be held in an investment portfolio;
 • privacy;
 • deposits of securities;
 • transactions among affiliates;
 • restrictions on transactions that have the effect of inducing lenders to place business with the insurer;
 • cybersecurity;
 • limits on dividends payable (for a description of limits on dividends payable to us from MGIC, see Note 14 – "Statutory Information," to our consolidated financial statements in Item 8);
 • suitability of officers and directors; and
 • claims handling.

 Future regulation is expected to address the use of algorithms, artificial intelligence and data and analytics in underwriting to determine pricing and for other purposes.
 Wisconsin, our domiciliary state, has adopted the Risk Management and Own Risk and Solvency Assessment Act, which requires, among other things, that we conduct an Own Risk and Solvency Assessment ("ORSA"), at least annually, to assess the material risks associated with our business and our current and estimated projected future solvency position; and maintain a risk management

 MGIC Investment Corporation 2024 Form 10-K | 23

 framework to assess, monitor, manage and report on material risks. Wisconsin has also adopted the annual enterprise risk reporting, group capital calculation, and "Corporate Governance Disclosure" requirements of the relevant NAIC model laws and regulations.

 The insurance laws of 16 jurisdictions, including Wisconsin, our domiciliary state, require a mortgage insurer to maintain a minimum amount of statutory capital relative to the RIF (or a similar measure) in order for the mortgage insurer to continue to write new business. We refer to these requirements as the "State Capital Requirements." While they vary among jurisdictions, currently the most common State Capital Requirements allow for a maximum risk-to-capital ratio of 25 to 1. Wisconsin does not regulate capital by using a risk-to-capital measure but instead requires a minimum policyholder position. MGIC's "policyholder position" includes its net worth or surplus and its contingency reserve.

 At December 31, 2024, MGIC's risk-to-capital ratio was 10.0 to 1, below the maximum allowed by the jurisdictions with State Capital Requirements, and its policyholder position was $3.6 billion above the required MPP of $2.2 billion.

 In August 2023, the NAIC adopted a revised Mortgage Guaranty Insurance Model Act. The revised Model Act includes requirements relating to, among other things: (i) capital and minimum capital requirements, and contingency reserves; (ii) restrictions on mortgage insurers' investments in notes secured by mortgages; (iii) prudent underwriting standards and formal underwriting guidelines; (iv) the establishment of formal, internal "Mortgage Guaranty Quality Control Programs" with respect to in-force business; and (v) reinsurance and prohibitions on captive reinsurance arrangements. It is uncertain when the revised Model Act will be adopted in any jurisdiction. The provisions of the Model Act, if adopted in their final form, are not expected to have a material adverse effect on our business. It is unknown whether any changes will be made by state legislatures prior to adoption, and the effect changes, if any, will have on the mortgage guaranty insurance market generally, or on our business. Wisconsin, where MGIC is domiciled, has begun the process to replace current PMI regulations with the Model Act, though it is expected that some changes will be made before formal adoption. See our risk factors "We may not continue to meet the GSEs' mortgage insurer eligibility requirements and our returns may decrease as we are required to maintain significantly more capital in order to maintain our eligibility" and "State Capital requirements may prevent us from continuing to write new insurance on an uninterrupted basis" in Item 1A, for information about regulations governing our capital adequacy and our expectations regarding our future capital position. See "Management's Discussion and Analysis – Liquidity and Capital Resources – Capital Adequacy" in Item 7 for information about our current capital position.

 We are required to establish statutory accounting contingency loss reserves in an amount equal to 50% of earned premiums. These amounts cannot be withdrawn for a period of 10 years, except as permitted by insurance regulations. With regulatory approval, a mortgage insurance company may make early withdrawals from the contingency reserve when incurred losses exceed 35% of premiums earned in a calendar year. Although MGIC holds assets in excess of its minimum statutory capital requirements and its PMIERs financial requirements, the ability of MGIC to pay dividends is restricted by insurance regulation. In general, dividends in excess of prescribed limits are deemed "extraordinary" and may not be paid if disapproved by the OCI. The level of ordinary dividends that may be paid without OCI approval is determined on an annual basis. A dividend is extraordinary when the proposed dividend amount, plus dividends paid in the twelve months preceding the dividend payment date exceed the ordinary dividend level. In 2025, MGIC can pay $97 million of ordinary dividends without OCI approval, before taking into consideration dividends paid in the preceding twelve months. In 2024, MGIC paid $750 million in dividends to the holding company. For further information, see Note 14 – "Statutory Information," to our consolidated financial statements in Item 8.

 Mortgage insurance premium rates are subject to state regulation to protect policyholders against the adverse effects of excessive, inadequate or unfairly discriminatory rates and to encourage competition in the insurance marketplace. Any increase in premium rates must be justified, generally on the basis of the insurer's loss experience, expenses and future trend analysis. The general mortgage default experience may also be considered. Premium rates are subject to review and challenge by state regulators.

 Mortgage insurers are generally single-line companies, restricted to writing residential mortgage insurance business only. Although we, as an insurance holding company, are prohibited from engaging in certain transactions with MGIC or our other insurance subsidiaries without submission to and, in some instances, prior approval by applicable insurance departments, we are not subject to insurance company regulation on our non-insurance businesses.

 Wisconsin's insurance regulations generally provide that no person may acquire control of us unless the transaction in which control is acquired has been approved by the OCI. The regulations provide for a rebuttable presumption of control when a person owns or has the right to vote more than 10% of the voting securities. In addition, the insurance regulations of other states in which MGIC is licensed require notification to the state's insurance department a specified time before a person acquires control of us. If regulators in these states disapprove the change of control, our licenses to conduct business in the disapproving states could be terminated. For further information about regulatory proceedings applicable to us and our industry, see "We are subject to comprehensive regulation and other requirements, which we may fail to satisfy" in Item 1A.

 The CFPB's rules implementing laws that require mortgage lenders to make ability-to-pay determinations prior to extending credit affect the characteristics of loans being originated and the volume of loans available to be insured. We are uncertain whether the CFPB will issue any other rules or regulations that affect our business. Such rules and regulations could have a material adverse effect on us.

 As the most significant purchasers and sellers of conventional mortgage loans and beneficiaries of private mortgage insurance, the GSEs impose financial and other requirements on private mortgage insurers in order for them to be eligible to insure loans sold to the GSEs (these requirements are referred to as the "PMIERs", as discussed above). These requirements are subject to change from time to

 MGIC Investment Corporation 2024 Form 10-K | 24

 time. Based on our interpretation of the financial requirements of the PMIERs, as of December 31, 2024, MGIC's Available Assets totaled $5.8 billion, or $2.2 billion in excess of its Minimum Required Assets. MGIC is in compliance with the requirements of the PMIERs and eligible to insure loans purchased by the GSEs. If MGIC ceases to be eligible to insure loans purchased by one or both of the GSEs, it would significantly reduce the volume of our new business writings. For information about matters that could negatively affect our compliance with the PMIERs, see our risk factor titled "We may not continue to meet the GSEs' mortgage insurer eligibility requirements and our returns may decrease as we are required to maintain significantly more capital in order to maintain our eligibility" in Item 1A.

 The FHFA has been the conservator of the GSEs since 2008 and has the authority to control and direct their operations. The increased role that the federal government has assumed in the residential housing finance system through the GSE conservatorship may increase the likelihood that the business practices of the GSEs change, including through administrative action. Such changes, or the release of the GSEs from conservatorship, could have a material adverse effect on us. For more information about the business practices of the GSEs that impact our business, see our risk factor titled "Changes in the business practices of Fannie Mae and Freddie Mac ("the GSEs"), federal legislation that changes their charters or a restructuring of the GSEs could reduce our revenues or increase our losses." in Item 1A.

 INDIRECT REGULATION
 We are also indirectly, but significantly, impacted by regulations affecting purchasers of mortgage loans, such as the GSEs, and regulations affecting government insurers, such as the FHA and the VA, and lenders. Private mortgage insurers, including MGIC, are highly dependent upon federal housing legislation and other laws and regulations to the extent they affect the demand for private mortgage insurance and the housing market generally. From time to time, those laws and regulations have been amended in ways that affect competition from government agencies. Proposals are discussed from time to time by Congress and certain federal agencies to reform or modify the FHA and the Government National Mortgage Association, which securitizes mortgages insured by the FHA.

 Mortgage insurance generally may be considered to be a "settlement service" for purposes of RESPA under applicable regulations. Subject to certain exceptions, in general, RESPA prohibits any person from giving or receiving any "thing of value" pursuant to an agreement or understanding to refer settlement services.

 HOPA provides for the automatic termination, or cancellation upon a borrower's request, of private mortgage insurance upon satisfaction of certain conditions. For more information, see "Our Products and Services" in Item 1.B.

 FCRA imposes restrictions on the permissible use of credit report information. FCRA has been interpreted by some Federal Trade Commission staff and federal courts to require mortgage insurance companies to provide "adverse action" notices to consumers in the event an application for mortgage insurance is declined or offered at less than the best available rate for the loan program applied for on the basis of a review of the consumer's credit.

 The Office of the Comptroller of the Currency, the Federal Reserve Board, and the Federal Deposit Insurance Corporation have uniform guidelines on real estate lending by insured lending institutions under their supervision. The guidelines specify that a residential mortgage loan originated with loan-to-value ratios above certain levels should have appropriate credit enhancement in the form of mortgage insurance or readily marketable collateral, although no depth of coverage percentage is specified in the guidelines.

 Lenders are subject to various laws, including the Home Mortgage Disclosure Act, the Community Reinvestment Act, the Equal Credit Opportunity Act, TILA, HOPA, the Secure and Fair Enforcement for Mortgage Licensing Act, FCRA, the Fair Debt Collection Practices Act, the Gramm-Leach-Bliley Act, and the Fair Housing Act. Fannie Mae and Freddie Mac are subject to various laws, including laws relating to government sponsored enterprises, which may impose obligations or create incentives for increased lending to low and moderate income persons, or in targeted areas.

 There can be no assurance that other federal laws and regulations affecting these institutions and entities will not change, or that new legislation or regulations will not be adopted which will adversely affect the private mortgage insurance industry.

 G. Human Capital
 Our talent practices reflect a commitment to creating a positive co-worker experience. We continue to support our co-workers in their career journeys and work to further connect them to each other and the community.
 As of December 31, 2024, we had 555 co-workers not including "on-call" and part-time co-workers. The number of "on-call" co-workers can vary substantially, primarily as a result of changes in demand for our services. In recent years, the number of "on-call" co-workers has ranged from fewer than 10 to more than 110.

 TOTAL REWARDS AND TALENT PRACTICES
 Our total rewards program is designed to provide a competitive package of benefits and compensation elements that recognize the unique needs of our workforce and their families. All full-time MGIC co-workers are eligible to participate in our health program, in addition to a comprehensive medical, dental and vision plan. We also recognize financial health as part of well-being, and currently provide a 401(k) plan with a company match and discretionary annual profit-sharing contributions for qualifying employees.

 CO-WORKER SENTIMENT
 MGIC conducts an annual engagement survey to gauge co-worker sentiment and connection to company values. Based on the survey results, we identify and share with our Board of Directors and executive leadership areas of strength and opportunity. For transparency, these strengths and opportunities are shared with all co-workers, and leaders at all levels of the company are expected to play an active role in taking meaningful action in response. The annual engagement survey is complemented by additional quantitative, qualitative and passive listening mechanisms, ranging from new hire surveys to CEO-led focus groups.

 COMMUNITY INVOLVEMENT
 Our commitment to community is formalized under the banner of Giving Back, Together, and in 2024 included providing financial and in-kind support for organizations that support housing, youth programs, and the arts in our community and nationwide. We also provided paid time off for co-workers to volunteer or work at election polling places.

 H. Website Access
 We make available, free of charge, our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, and amendments to those reports filed or furnished to the Securities and Exchange Commission ("SEC") as soon as reasonably practicable after we electronically file these materials with the SEC. The reports and amendments are accessible at the "Reports & Filings" link on our website ( The inclusion of our website address in this report is an inactive textual reference only and is not intended to include or incorporate by reference the information on our website into this report.

 Item 1A. Risk Factors
 As used below, "we," "our" and "us" refer to MGIC Investment Corporation's consolidated operations or to MGIC Investment Corporation, as the context requires; and "MGIC" refers to Mortgage Guaranty Insurance Corporation.
 Risk Factors Relating to Global Events
 Wars and/or other global events may adversely affect the U.S. economy and our business.
 Wars and/or other global events may result in increased inflation rates, strained supply chains, and increased volatility in the domestic and global financial markets. Wars and/or other global events have in the past and may continue to impact our business in various ways, including the following which are described in more detail in the remainder of these risk factors:
 • The terms under which we are able to obtain quota share reinsurance ("QSR") and/or excess-of-loss ("XOL") reinsurance through the insurance-linked notes ("ILN") market and the traditional reinsurance market may be negatively impacted and terms under which we are able to access those markets in the future may be limited or less attractive.
 • The risk of a cybersecurity incident that affects our company may increase.
 • Wars may negatively impact the domestic economy, which may increase unemployment and inflation, or decrease home prices, in each case leading to an increase in loan delinquencies.
 • The volatility in the financial markets may impact the performance of our investment portfolio and our investment portfolio may include investments in companies or securities that are negatively impacted by wars and/or other global events.
 Risk Factors Relating to the Mortgage Insurance Industry and its Regulation
 Downturns in the domestic economy or declines in home prices may result in more homeowners defaulting and our losses increasing, with a corresponding decrease in our returns.
 Losses result from general economic or personal events that reduce a borrower's ability or willingness to make mortgage payments, such as recession, unemployment, decreases in home prices, health issues, and changes in family status. Such events are outside of our control, difficult to predict, and generally increase loan delinquencies and claims. Additionally, economic conditions may differ from region to region. Information about the geographic dispersion of our risk in force and delinquency inventory can be found in our Annual Reports on Form 10-K and our Quarterly Reports on Form 10-Q.
 A decline in home prices may make it more difficult for borrowers to sell or refinance their homes, increasing the chances of default. Additionally, a decline in home prices may result in loan balances exceeding home values, discouraging borrowers from continuing to make payments. The seasonally-adjusted Purchase-Only U.S. Home Price Index of the Federal Housing Finance Agency (the "FHFA"), which is based on single-family properties whose mortgages have been purchased or securitized by Fannie Mae or Freddie Mac, indicates that home prices increased.3% nationwide in November, 2024 compared to October, 2024. Although the 12 month change in home prices recently reached historically high rates, the rate of growth is moderating: it increased by 4.1% in the first 11 months of 2024, after increasing 6.7%, 6.8%, and 17.8% in 2023, 2022, and 2021, respectively. The national average price-to-income ratio exceeds its historical average, in part as a result of recent home price appreciation outpacing increases in income. Affordability issues can put downward pressure on home prices. A decline in home prices may occur even absent a deterioration in economic conditions due to declines in demand for homes, which in turn may result from changes in buyers' perceptions of the potential for future appreciation, restrictions on and the cost of mortgage credit due to more stringent underwriting standards, higher interest rates, changes to the tax deductibility of mortgage interest, decreases in the rate of household formations, or other factors.
 Changes in the business practices of Fannie Mae and Freddie Mac ("the GSEs"), federal legislation that changes their charters or a restructuring of the GSEs could reduce our revenues or increase our losses.
 The substantial majority of our new insurance written ("NIW") is for loans purchased by the GSEs; therefore, the business practices of the GSEs greatly impact our business. The GSEs possess substantial market power, which enables them to influence our business and the mortgage insurance industry in general. In 2008 the housing market was in severe decline, which damaged the financial condition of the GSEs. FHFA placed the GSEs into conservatorship on September 7, 2008 and the FHFA has the authority to control and direct their operations. Given that the Director of the FHFA serves at the pleasure of the President, the agency's agenda, policies and actions may be influenced by the then-current administration. When a new administration is sworn in, the policy direction and oversight of the GSEs may change.

 Changes in the status, powers, or supervision of the GSEs, whether through legislation or administrative action, could impact private mortgage insurers, which would have an adverse effect on our business, revenue, results of operations and financial condition. Business practices of the GSEs that affect the mortgage insurance industry include:

 MGIC Investment Corporation 2024 Form 10-K | 27

 • The GSEs' private mortgage insurer eligibility requirements ("PMIERs"), the financial requirements of which are discussed in our risk factor titled "We may not continue to meet the GSEs' private mortgage insurer eligibility requirements and our returns may decrease if we are required to maintain more capital in order to maintain our eligibility."
 • The capital and collateral requirements for participants in the GSEs' alternative forms of credit enhancement discussed in our risk factor titled "The amount of insurance we write could be adversely affected if lenders and investors select alternatives to private mortgage insurance or are unable to obtain capital relief for mortgage insurance."
 • The level of private mortgage insurance coverage, subject to the limitations of the GSEs' charters, when private mortgage insurance is used as the required credit enhancement on low down payment mortgages (the GSEs generally require a level of mortgage insurance coverage that is higher than the level of coverage required by their charters; any change in the required level of coverage will impact our new risk written).
 • The amount of loan level price adjustments and guaranty fees (which result in higher costs to borrowers) that the GSEs assess on loans that require private mortgage insurance. The requirements of the new GSE capital framework may lead the GSEs to increase their guaranty fees. In addition, the FHFA has indicated that it is reviewing the GSEs' pricing in connection with preparing them to exit conservatorship and to ensure that pricing subsidies benefit only affordable housing activities.
 • Whether the GSEs select or influence the mortgage lender's selection of the mortgage insurer providing coverage.
 • The underwriting standards that determine which loans are eligible for purchase by the GSEs, which can affect the quality of the risk insured by the mortgage insurer and the availability of mortgage loans.
 • The terms on which mortgage insurance coverage can be canceled before reaching the cancellation thresholds established by law and the business practices associated with such cancellations. If the GSEs or other mortgage investors change their practices regarding the timing of cancellation of mortgage insurance due to home price appreciation, policy goals, changing risk tolerances or otherwise, we could experience an unexpected reduction in our insurance in force ("IIF"), which would negatively impact our business and financial results. For more information, see the discussion below regarding the GSEs' Equitable Housing Plans and our risk factor titled "The length of time our insurance policies remain in force has a significant impact on our results."
 • The programs established by the GSEs intended to avoid or mitigate loss on insured mortgages and the circumstances in which mortgage servicers must implement such programs.
 • The terms that the GSEs require to be included in mortgage insurance policies for loans that they purchase, including limitations on the rescission rights of mortgage insurers.
 • The extent to which the GSEs intervene in mortgage insurers' claims paying practices, rescission practices or rescission settlement practices with lenders.
 • The maximum loan limits of the GSEs compared to those of the Federal Housing Administration ("FHA") and other investors.
 • The benchmarks established by the FHFA for loans to be purchased by the GSEs, which can affect the loans available to be insured. In December 2021, the FHFA established the benchmark levels for 2022-2024 purchases of low-income home mortgages, very low-income home mortgages and low-income refinance mortgages, each of which exceeded the 2021 benchmarks. The FHFA also established two new sub-goals: one targeting minority communities and the other targeting low-income neighborhoods. In August 2024, FHFA proposed new benchmark levels for 2025-2027 purchases of low-income home mortgages, very low-income home mortgages and low-income refinance mortgages. The newly-proposed levels for low-income and very low-income home mortgages are lower than the 2022-2024 levels, but are higher than pre-2022 levels. The newly-proposed level for low income refinance mortgages is unchanged from the 2022-2024 level, but is higher than the pre-2022 level.
 In recent years, primarily at the direction of FHFA, the GSEs have been focused on, among other things, the promotion of access, affordability, and equitable housing initiatives. In 2022 the GSEs each published Equitable Housing Finance Plans ("Plans"). Updated Plans were published by the GSEs in the spring of 2024. The Plans seek to advance equity in housing finance over a three-year period and include potential changes to the GSEs' business practices and policies. Specifically relating to mortgage insurance, (1) Fannie Mae's Plan includes the creation of special purpose credit program(s) ("SPCPs") targeted to historically underserved borrowers and the support of locally-controlled SPCPs with a goal of lowering costs for such borrowers through lower than standard mortgage insurance requirements; and (2) Freddie Mac's Plan includes plans to work with mortgage insurers to look for ways to lower mortgage costs, the creation of SPCPs targeted to historically underserved borrowers, and the planned purchase of loans originated through lender-created SPCPs. To the extent the business practices and policies of the GSEs regarding mortgage insurance coverage, costs and cancellation change, including more broadly than through SPCPs, such changes may negatively impact the mortgage insurance industry and our financial results.
 It is uncertain what role the GSEs, FHA and private capital, including private mortgage insurance, will play in the residential housing finance system in the future. The timing and impact on our business of any resulting changes are uncertain. For changes that would require Congressional action to implement it is difficult to estimate when Congressional action would be final and how long any associated phase-in period may last.

 MGIC Investment Corporation 2024 Form 10-K | 28

 We may not continue to meet the GSEs' private mortgage insurer eligibility requirements and our returns may decrease if we are required to maintain more capital in order to maintain our eligibility.
 We must comply with a GSE's PMIERs to be eligible to insure loans delivered to or purchased by that GSE. The PMIERs include financial requirements, as well as business, quality control and certain transaction approval requirements. The PMIERs provide that the GSEs may amend any provision of the PMIERs or impose additional requirements with an effective date specified by the GSEs.
 The financial requirements of the PMIERs require a mortgage insurer's "Available Assets" (generally only the most liquid assets of an insurer) to equal or exceed its "Minimum Required Assets" (which are generally based on an insurer's book of risk in force and calculated from tables of factors with several risk dimensions, reduced for credit given for risk ceded under reinsurance agreements).
 Based on our interpretation of the PMIERs, as of December 31, 2024, MGIC's Available Assets totaled $5.8 billion, or $2.2 billion in excess of its Minimum Required Assets. MGIC is in compliance with the PMIERs and eligible to insure loans purchased by the GSEs. In August 2024, the GSEs issued updates to the calculation of Available Assets. The update will be implemented through a 24-month phased-in approach, with a fully effective date of September 30, 2026. If these changes were effective as of December 31, 2024, without a graduated implementation period, MGIC's Available Assets of $5.8 billion would decrease by approximately 1% or $50 million, and MGIC's PMIERs excess would be $2.1 billion.
 Our Minimum Required Assets reflect a credit for risk ceded under our QSR and XOL reinsurance transactions, which are discussed in our risk factor titled "Our underwriting practices and the mix of business we write affects our Minimum Required Assets under the PMIERs, our premium yields and the likelihood of losses occurring." The calculated credit for XOL reinsurance transactions under PMIERs is generally based on the PMIERs requirement of the covered loans and the attachment and detachment points of the coverage, all of which fluctuate over time. PMIERs credit is generally not given for the reinsured risk above the PMIERs requirement. The GSEs have discretion to further limit reinsurance credit under the PMIERs. Refer to "Consolidated Results of Operations – Reinsurance Transactions" in Part I, Item 2 of our Quarterly Report on Form 10-Q for information about the calculated PMIERs credit for our XOL transactions. There is a risk we will not receive our current level of credit in future periods for ceded risk. In addition, we may not receive the same level of credit under future reinsurance transactions that we receive under existing transactions. If MGIC is not allowed certain levels of credit under the PMIERs, under certain circumstances, MGIC may terminate the reinsurance transactions without penalty.
 The PMIERs generally require us to hold significantly more Minimum Required Assets for delinquent loans than for performing loans and the Minimum Required Assets required to be held increases as the number of payments missed on a delinquent loan increases. If the number of loan delinquencies increases for reasons discussed in these risk factors, or otherwise, it may cause our Minimum Required Assets to exceed our Available Assets. We are unable to predict the ultimate number of loans that will become delinquent. If we are required to hold more capital relative to our insured loans it could adversely affect our business and results of operations, or prohibit or delay us from taking actions that would be advantageous to our investors.
 If our Available Assets fall below our Minimum Required Assets, we would not be in compliance with the PMIERs. The PMIERs provide a list of remediation actions for a mortgage insurer's non-compliance, with additional actions possible in the GSEs' discretion. At the extreme, the GSEs may suspend or terminate our eligibility to insure loans purchased by them. Such suspension or termination would significantly reduce the volume of our NIW, the substantial majority of which is for loans delivered to or purchased by the GSEs.
 Additionally, the PMIERs impose transactional approval conditions that may restrict or delay us from taking certain actions. In the event that one or both of the GSEs does not approve an intended course of action, there may be a material adverse effect on our business and results of operations.
 Should capital be needed by MGIC in the future, capital contributions from our holding company may not be available due to competing demands on holding company resources.
 Because loss reserve estimates are subject to uncertainties, paid claims may be substantially different than our loss reserves.
 When we establish case reserves, we estimate our ultimate loss on delinquent loans by estimating the number of such loans that will result in a claim payment (the "claim rate"), and further estimating the amount of the claim payment (the "claim severity"). Changes to our claim rate and claim severity estimates could have a material impact on our future results, even in a stable economic environment. Our estimates incorporate anticipated cures, loss mitigation activity, rescissions and curtailments. The establishment of loss reserves is subject to inherent uncertainty and requires significant judgment by management. Our actual claim payments may differ substantially from our loss reserve estimates. Our estimates could be affected by several factors, including a change in regional or national economic conditions as discussed in these risk factors and a change in the length of time loans are delinquent before claims are received. Generally, the longer a loan is delinquent before a claim is received, the greater the severity. Foreclosure moratoriums and forbearance programs increase the average time it takes to receive claims. Generally, losses follow a seasonal trend in which the first half of the year has stronger credit performance than the second half, with higher cure rates and lower new notice activity. The state of the economy, local housing markets, pandemics, natural disasters, and various other factors, may result in delinquencies not following the typical pattern.
 We are subject to comprehensive regulation and other requirements, which we may fail to satisfy.
 We are subject to comprehensive regulation, including by state insurance departments. Many regulations are designed for the protection of our insured policyholders and consumers, rather than for the benefit of investors. Mortgage insurers, including MGIC, have

 MGIC Investment Corporation 2024 Form 10-K | 29

 in the past been involved in litigation and regulatory actions related to alleged violations of the anti-referral fee provisions of the Real Estate Settlement Procedures Act ("RESPA"), and the notice provisions of the Fair Credit Reporting Act ("FCRA"). While these proceedings in the aggregate did not result in material liability for MGIC, there can be no assurance that the outcome of future proceedings, if any, under these laws or others would not have a material adverse effect on us.
 We provide contract underwriting services, including on loans for which we are not providing mortgage insurance. These services are subject to contractual obligations and federal and state regulation. Our failure to meet the standards set forth in the applicable contracts or regulations would subject us to potential litigation or regulatory action. To the extent that we are construed to make independent credit decisions in connection with our contract underwriting activities, we also could be subject to increased regulatory requirements under the Equal Credit Opportunity Act ("ECOA"), FCRA, and other laws. Under relevant laws, examination may also be made of whether a mortgage insurer's underwriting decisions have a disparate impact on persons belonging to a protected class in violation of the law.
 Although their scope varies, state insurance laws generally grant broad supervisory powers to agencies or officials to examine insurance companies and enforce rules or exercise discretion affecting almost every significant aspect of the insurance business, including payment for the referral of insurance business, premium rates and discrimination in pricing, and minimum capital requirements. The increased use by the private mortgage insurance industry of risk-based pricing systems that establish premium rates based on more attributes than previously considered, and of algorithms, artificial intelligence and data and analytics, has led to additional regulatory scrutiny of premium rates and of other matters such as discrimination in pricing and underwriting, data privacy and access to insurance. For more information about state capital requirements, see our risk factor titled "State capital requirements may prevent us from continuing to write new insurance on an uninterrupted basis." For information about regulation of data privacy, see our risk factor titled "We could be materially adversely affected by a cybersecurity breach or failure of information security controls." For more details about the various ways in which our subsidiaries are regulated, see "Business - Regulation" in Item 1 of our Annual Report on Form 10-K for the year ended December 31, 2023.
 While we have established policies and procedures to comply with applicable laws and regulations, many such laws and regulations are complex and it is not possible to predict the eventual scope, duration or outcome of any reviews or investigations nor is it possible to predict their effect on us or the mortgage insurance industry.

 Pandemics, hurricanes and other disasters may adversely impact our results of operations and financial condition.
 Pandemics and other disasters, such as hurricanes, tornadoes, earthquakes, wildfires and floods, or other events related to climate change, could trigger an economic downturn in the affected areas, or in areas with similar risks, which could result in a decrease in home prices, an increased claim rate and increased claim severity in those areas. Due to the increased frequency and severity of natural disasters, some homeowners' insurers are increasing premium rates or withdrawing from certain states or areas that they deem to be high risk. Even though we do not generally insure losses related to property damage, the inability of a borrower to obtain hazard and/or flood insurance, or the increased cost of such insurance, could lead to a decrease in home prices in the affected areas and an increase in delinquencies and our incurred losses.
 The PMIERs require us to maintain significantly more "Minimum Required Assets" for delinquent loans than for performing loans. See our risk factor titled "We may not continue to meet the GSEs' private mortgage insurer eligibility requirements and our returns may decrease if we are required to maintain more capital in order to maintain our eligibility."
 Pandemics and other disasters could also lead to increased reinsurance rates or reduced availability of reinsurance. This may cause us to retain more risk than we otherwise would and could negatively affect our compliance with the financial requirements of State Capital Requirements and the PMIERs. Similarly, pandemics and other disasters may impact the value of and cause volatility in our investment portfolio, which could also negatively affect our compliance with the financial requirements of PMIERs.
 FHFA is working to incorporate climate risk considerations into its policy development and processes. The FHFA has instructed the GSEs to designate climate change as a priority concern and actively consider its effects in their decision making. FHFA has established internal working groups and a steering committee in order to ensure that the GSEs are accounting for the risks associated with climate change and natural disasters. In May 2024, FHFA published an advisory bulletin highlighting the need for the GSEs to establish, as appropriate, risk management practices that identify, assess, control, monitor and report climate-related risks, and the need to have appropriate risk management policies, standards, procedures, controls and reporting systems in place. It is possible that efforts to manage these risks by the FHFA, GSEs (including through GSE guideline or mortgage insurance policy changes) or others could materially impact the volume and characteristics of our NIW (including its policy terms), home prices in certain areas and defaults by borrowers in certain areas.
 Reinsurance may be unavailable at current levels and prices, and/or the GSEs may reduce the amount of capital credit we receive for our reinsurance transactions.
 We have in place QSR and XOL reinsurance transactions providing various amounts of coverage on our risk in force as of December 31, 2024. Refer to Part 1, Note 4 – "Reinsurance" and Part 1, Item 2 "Consolidated Results of Operations – Reinsurance Transactions" of our Quarterly Report on Form 10-Q, for more information about coverage under our reinsurance transactions. The reinsurance transactions reduce the tail-risk associated with stress scenarios. As a result, they reduce the risk-based capital that we are required to hold to support the risk and they allow us to earn higher returns on risk-based capital for our business than we would without them.

 MGIC Investment Corporation 2024 Form 10-K | 30

 However, market conditions impact the availability and cost of reinsurance. Reinsurance may not always be available to us, or available only on terms or at costs that we consider unacceptable. If we are not able to obtain reinsurance we will be required to hold additional capital to support our risk in force.

 Reinsurance transactions subject us to counterparty risk, including the financial capability of the reinsurers to make payments for losses ceded to them under the reinsurance agreements. As reinsurance does not relieve us of our obligation to pay claims to our policyholders, our inability to recover losses from a reinsurer could have a material impact on our results of operations and financial condition.

 The GSEs may change the credit they allow under the PMIERs for risk ceded under our reinsurance transactions. If the GSEs were to reduce the credit that we receive for reinsurance under the PMIERs, it could result in decreased returns absent an increase in our premium rates. An increase in our premium rates to adjust for a decrease in reinsurance credit may lead to a decrease in our NIW and net income.

 Because we establish loss reserves only upon a loan delinquency rather than based on estimates of our ultimate losses on risk in force, losses may have a disproportionate adverse effect on our earnings in certain periods.
 In accordance with accounting principles generally accepted in the United States, we establish case reserves for insurance losses and loss adjustment expenses only when delinquency notices are received for insured loans that are two or more payments past due and for loans we estimate are delinquent but for which delinquency notices have not yet been received (which we include in "IBNR"). Losses that may occur from loans that are not delinquent are not reflected in our financial statements, except when a "premium deficiency" is recorded. A premium deficiency would be recorded if the present value of expected future losses and expenses exceeds the present value of expected future premiums and already established loss reserves on the applicable loans. As a result, future losses incurred on loans that are not currently delinquent may have a material impact on future results as delinquencies emerge. As of December 31, 2024, we had established case reserves and reported losses incurred for 26,791 loans in our delinquency inventory and our IBNR reserve totaled $29 million. The number of loans in our delinquency inventory may increase from that level as a result of economic conditions relating to current global events or other factors and our losses incurred may increase.
 State capital requirements may prevent us from continuing to write new insurance on an uninterrupted basis.
 The insurance laws of 16 jurisdictions, including Wisconsin, MGIC's domiciliary state, require a mortgage insurer to maintain a minimum amount of statutory capital relative to its risk in force (or a similar measure) in order for the mortgage insurer to continue to write new business. We refer to these requirements as the "State Capital Requirements." While they vary among jurisdictions, the most common State Capital Requirements allow for a maximum risk-to-capital ratio of 25 to 1. A risk-to-capital ratio will increase if (i) the percentage decrease in capital exceeds the percentage decrease in insured risk, or (ii) the percentage increase in capital is less than the percentage increase in insured risk. Wisconsin does not regulate capital by using a risk-to-capital measure but instead requires a minimum policyholder position ("MPP"). MGIC's "policyholder position" includes its net worth, or surplus, and its contingency reserve.
 At December 31, 2024, MGIC's risk-to-capital ratio was 10.0 to 1, below the maximum allowed by the jurisdictions with State Capital Requirements, and its policyholder position was $3.6 billion above the required MPP of $2.2 billion. Our risk-to-capital ratio and MPP reflect credit for the risk ceded under our reinsurance agreements with unaffiliated reinsurers. If MGIC is not allowed an agreed level of credit under the State Capital Requirements, MGIC may terminate the reinsurance transactions, without penalty.
 In 2023, the NAIC adopted a revised Mortgage Guaranty Insurance Model Act. The updated Model Act includes requirements relating to, among other things: (i) capital and minimum capital requirements, and contingency reserves; (ii) restrictions on mortgage insurers' investments in notes secured by mortgages; (iii) prudent underwriting standards and formal underwriting guidelines; (iv) the establishment of formal, internal "Mortgage Guaranty Quality Control Programs" with respect to in-force business; and (v) reinsurance and prohibitions on captive reinsurance arrangements. It is uncertain when the revised Model Act will be adopted in any jurisdiction. The provisions of the Model Act, if adopted in their final form, are not expected to have a material adverse effect on our business. It is unknown whether any changes will be made by state legislatures prior to adoption, and the effect changes, if any, will have on the mortgage guaranty insurance market generally, or on our business. Wisconsin, where MGIC is domiciled, has begun the process to replace current mortgage insurance regulations with the Model Act, though it is expected that some changes will be made before formal adoption.
 While MGIC currently meets the State Capital Requirements of Wisconsin and all other jurisdictions, it could be prevented from writing new business in the future in all jurisdictions if it fails to meet the State Capital Requirements of Wisconsin, or it could be prevented from writing new business in a particular jurisdiction if it fails to meet the State Capital Requirements of that jurisdiction, and in each case if MGIC does not obtain a waiver of such requirements. It is possible that regulatory action by one or more jurisdictions, including those that do not have specific State Capital Requirements, may prevent MGIC from continuing to write new insurance in such jurisdictions. If we are unable to write business in a particular jurisdiction, lenders may be unwilling to procure insurance from us anywhere. In addition, a lender's assessment of the future ability of our insurance operations to meet the State Capital Requirements or the PMIERs may affect its willingness to procure insurance from us. In this regard, see our risk factor titled "Competition or changes in our relationships with our customers could reduce our revenues, reduce our premium yields and/or increase our losses." A possible future failure by MGIC to meet the State Capital Requirements or the PMIERs will not necessarily mean that MGIC lacks sufficient resources to pay claims on its insurance liabilities. You should read the rest of these risk factors for information about matters that could negatively affect MGIC's compliance with State Capital Requirements and its claims paying resources.

 If the volume of low down payment home mortgage originations declines, the amount of insurance that we write could decline.
 The factors that may affect the volume of low down payment mortgage originations include the health of the U.S. economy; conditions in regional and local economies and the level of consumer confidence; the health and stability of the financial services industry; restrictions on mortgage credit due to more stringent underwriting standards, liquidity issues or risk-retention and/or capital requirements affecting lenders; the level of home mortgage interest rates; housing affordability; new and existing housing availability; the rate of household formation, which is influenced, in part, by population and immigration trends; homeownership rates; the rate of home price appreciation, which in times of heavy refinancing can affect whether refinanced loans have LTV ratios that require private mortgage insurance; tax policy; and government housing policy encouraging equitable housing and loans to first-time homebuyers. A decline in the volume of low down payment home mortgage originations could decrease demand for mortgage insurance and limit our NIW. For other factors that could decrease the demand for mortgage insurance, see our risk factor titled "The amount of insurance we write could be adversely affected if lenders and investors select alternatives to private mortgage insurance or are unable to obtain capital relief for mortgage insurance."
 The amount of insurance we write could be adversely affected if lenders and investors select alternatives to private mortgage insurance or are unable to obtain capital relief for mortgage insurance.
 Alternatives to private mortgage insurance include:
 • investors using risk mitigation and credit risk transfer techniques other than private mortgage insurance, or accepting credit risk without credit enhancement,
 • lenders and other investors holding mortgages in portfolio and self-insuring,
 • lenders using FHA, U.S. Department of Veterans Affairs ("VA") and other government mortgage insurance programs, and
 • lenders originating mortgages using piggyback structures to avoid private mortgage insurance, such as a first mortgage with an 80% loan-to-value ("LTV") ratio and a second mortgage with a 10%, 15% or 20% LTV ratio rather than a first mortgage with a 90%, 95% or 100% LTV ratio that has private mortgage insurance.
 The GSEs' charters generally require credit enhancement for a low down payment mortgage loan (a loan in an amount that exceeds 80% of a home's value) in order for such loan to be eligible for purchase by the GSEs. Private mortgage insurance generally has been purchased by lenders in primary mortgage market transactions to satisfy this credit enhancement requirement. In 2018, the GSEs initiated secondary mortgage market programs with loan level mortgage default coverage provided by various (re)insurers that are not mortgage insurers governed by PMIERs, and that are not selected by the lenders. These programs, which currently account for a small percentage of the low down payment market, compete with traditional private mortgage insurance and, due to differences in policy terms, they may offer premium rates that are below prevalent single premium lender-paid mortgage insurance ("LPMI") rates. We participate in these programs from time to time. See our risk factor titled "Changes in the business practices of Fannie Mae and Freddie Mac ("the GSEs"), federal legislation that changes their charters or a restructuring of the GSEs could reduce our revenues or increase our losses" for a discussion of various business practices of the GSEs that may be changed, including through expansion or modification of these programs.
 The GSEs (and other investors) have also used other forms of credit enhancement that did not involve traditional private mortgage insurance, such as engaging in credit-linked note transactions executed in the capital markets, or using other forms of debt issuances or securitizations that transfer credit risk directly to other investors, including competitors and an affiliate of MGIC; using other risk mitigation techniques in conjunction with reduced levels of private mortgage insurance coverage; or accepting credit risk without credit enhancement.
 Government-supported mortgage insurance programs are not subject to the same capital requirements, risk tolerance or business objectives as private mortgage insurance companies and generally have greater financial flexibility in setting their pricing, guidelines and capacity, which could put us at a competitive disadvantage. If the FHA or other government-supported mortgage insurance programs increase their share of the mortgage insurance market, our business could be affected. Factors that influence market share include relative rates and fees, underwriting guidelines and loan limits of the FHA, VA, private mortgage insurers and the GSEs; changes to the GSEs' business practices; lenders' perceptions of legal risks under FHA versus GSE programs; flexibility for the FHA to establish new products as a result of federal legislation and programs; returns expected to be obtained by lenders for Ginnie Mae securitization of FHA-insured loans compared to those obtained from selling loans to the GSEs for securitization; and differences in policy terms, such as the ability of a borrower to cancel insurance coverage under certain circumstances.
 The FHA's share of the low down payment residential mortgages that were subject to FHA, VA, USDA or primary private mortgage insurance was 33.5% in 2024, 33.2% in 2023, and 26.7% in 2022. Since 2012, the FHA's market share has been as low as 23.4% (2020) and as high as 42.1% (in 2012). In February, 2023 the FHA announced a 30-basis point decrease in its mortgage insurance premium rates. This rate reduction has negatively impacted our NIW. The extent of the future impact of this rate reduction, or that of any other future government-supported mortgage insurance program premium changes, on our NIW is uncertain.
 The VA's share of the low down payment residential mortgages that were subject to FHA, VA, USDA or primary private mortgage insurance was 24.5% in 2024, 21.5% in 2023, and 24.5% in 2022. Since 2012, the VA's market share has been as high as 30.9% (in

 MGIC Investment Corporation 2024 Form 10-K | 32

 2020). The VA's 2023 market share was the lowest since 2013 (22.8%). The VA program offers 100% LTV ratio loans for qualifying borrowers.
 In July 2023, the Federal Reserve Board, Federal Deposit Insurance Corporation, and the Office of the Comptroller of the Currency proposed a revised regulatory capital rule that would impose higher capital standards on large U.S. banks. Under the proposed regulation's new expanded risk-based approach, affected banks would no longer receive risk-based capital relief for mortgage insurance on loans held in their portfolios. If adopted as proposed, the regulation is expected to have a negative effect on our NIW; however, at this time it is difficult to predict the extent of the impact. In September 2024, it was announced that regulators may revise the proposed rule, including by lowering the proposed-risk weighting for loans secured by residential real estate. It is unknown at this time what, if any, effect this would have on our NIW. More recently, in November 2024, it was announced that the proposed rule will be placed on hold pending the installation of the new Presidential Administration.
 The length of time our insurance policies remain in force has a significant impact on our results.
 The premium from a single premium policy is collected upfront and generally earned over the estimated life of the policy. In contrast, premiums from monthly and annual premium policies are received each month or year, as applicable, and earned each month over the life of the policy. In each year, most of our premiums earned are from insurance that has been written in prior years. As a result, the length of time insurance remains in force, which is generally measured by annual persistency (the percentage of our insurance remaining in force from one year prior), is a significant determinant of our revenues. A higher than expected persistency rate may decrease the profitability from single premium policies because they will remain in force longer and may increase the incidence of claims that was estimated when the policies were written. A low persistency rate on monthly and annual premium policies will reduce future premiums but may also reduce the incidence of claims, while a high persistency on those policies will increase future premiums but may increase the incidence of claims.
 Our annual persistency rate was 84.8% at December 31, 2024, 86.1% at December 31, 2023, and 82.2% at December 31, 2022. Since 2018, our annual persistency rate ranged from a high of 86.3% at September 30, 2023, to a low of 60.7% at March 31, 2021. Our persistency rate is primarily affected by the level of current mortgage interest rates compared to the mortgage coupon rates on our insurance in force, which affects the vulnerability of the IIF to refinancing; and the current amount of equity that borrowers have in the homes underlying our insurance in force. The amount of equity affects persistency in the following ways:
 • Borrowers with significant equity may be able to refinance their loans without requiring mortgage insurance.
 • The Homeowners Protection Act ("HOPA") requires servicers to cancel mortgage insurance when a borrower's LTV ratio meets or is scheduled to meet certain levels, generally based on the original value of the home and subject to various conditions and exclusions.
 • The GSEs' mortgage insurance cancellation guidelines apply more broadly than HOPA and also consider a home's current value. For more information about the GSEs' guidelines and business practices, and how they may change, see our risk factor titled "Changes in the business practices of Fannie Mae and Freddie Mac ("the GSEs"), federal legislation that changes their charters or a restructuring of the GSEs could reduce our revenues or increase our losses."
 We are susceptible to disruptions in the servicing of mortgage loans that we insure and we rely on third-party reporting for information regarding the mortgage loans we insure.
 We depend on reliable, consistent third-party servicing of the loans that we insure. An increase in delinquent loans may result in liquidity issues for servicers. When a mortgage loan that is collateral for a mortgage-backed security ("MBS") becomes delinquent, the servicer is usually required to continue to pay principal and interest to the MBS investors, generally for four months, even though the servicer is not receiving payments from borrowers. This may cause liquidity issues, especially for non-bank servicers (who service approximately 55% of the loans underlying our IIF as of December 31, 2024) because they do not have the same sources of liquidity that bank servicers have.
 While there has been no disruption in our premium receipts through the fourth quarter of 2024, servicers who experience future liquidity issues may be less likely to advance premiums to us on policies covering delinquent loans or to remit premiums on policies covering loans that are not delinquent. Our policies generally allow us to cancel coverage on loans that are not delinquent if the premiums are not paid within a grace period.
 An increase in delinquent loans or a transfer of servicing resulting from liquidity issues, may increase the operational burden on servicers, cause a disruption in the servicing of delinquent loans and reduce servicers' abilities to undertake mitigation efforts that could help limit our losses.
 We have delegated authority to the GSEs to implement certain loss mitigation options (e.g., modifications, short sales, deeds-in-lieu and foreclosure bidding) on certain loans we insure. The GSEs in turn have delegated such authority to most of their approved servicers, pursuant to delegation agreements. Servicers who service GSE-owned loans are required to operate under the GSEs' required standards in accepting certain loss mitigation alternatives. We rely on these servicers to appropriately make decisions to mitigate our exposure to loss. In some cases, loss mitigation decisions may not be favorable to us and may increase the incidence of paid claims. Ineffective delegation procedures or the failure of servicers to operate pursuant to required standards may increase our losses and have an

 MGIC Investment Corporation 2024 Form 10-K | 33

 adverse effect on our business, financial condition and operating results. We may terminate delegation of these loss management decisions to the GSEs; however, such termination may adversely affect our relationship with the GSEs and servicers.
 The information presented in this report and on our website with respect to the mortgage loans we insure is based on information reported to us by third parties, including the servicers and originators of the mortgage loans, and information presented may be subject to lapses or inaccuracies in reporting from such third parties. In many cases, we may not be aware that information reported to us is incorrect until such time as a claim is made against us under the relevant insurance policy. We do not consistently receive monthly policy status information from servicers for single premium policies and may not be aware that the mortgage loans insured by such policies have been repaid. We periodically attempt to determine if coverage is still in force on such policies by asking the last servicer of record or through the periodic reconciliation of loan information with certain servicers. It may be possible that our reports continue to reflect, as active, policies on mortgage loans that have been repaid.
 Risk Factors Relating to Our Business Generally
 If our risk management programs are not effective in identifying, or adequate in controlling or mitigating, the risks we face, or if the models we use are inaccurate, it could have a material adverse impact on our business, results of operations and financial condition.
 Our enterprise risk management program, described in "Business - Our Products and Services - Risk Management" in Item 1 of our Annual Report on Form 10-K for the year ended December 31, 2023, may not be effective in identifying, or adequate in controlling or mitigating, the risks we face in our business.
 We employ proprietary and third-party models for a wide range of purposes, including the following: projecting losses, premiums, expenses, and returns; pricing products (through our risk-based pricing system); determining the techniques used to underwrite insurance; estimating reserves; evaluating risk; determining internal capital requirements; and performing stress testing. These models rely on estimates, projections, and assumptions that are inherently uncertain and may not always operate as intended. This can be especially true when extraordinary events occur, such as wars, periods of extreme inflation, pandemics, or environmental disasters related to changing climatic conditions. In addition, our models are being continuously updated over time. Changes in models or model assumptions could lead to material changes in our future expectations, returns, or financial results. The models we employ are complex, which could increase our risk of error in their design, implementation, or use. Also, the associated input data, assumptions, and calculations may not always be correct or accurate and the controls we have in place to mitigate these risks may not be effective in all cases. The risks related to our models may increase when we change assumptions, methodologies, or modeling platforms. Moreover, we may use information we receive through enhancements to refine or otherwise change existing assumptions and/or methodologies.

 Information technology system failures or interruptions may materially impact our operations and/or adversely affect our financial results.
 We are heavily dependent on our information technology systems to conduct our business. Our ability to efficiently operate our business depends significantly on the reliability and capacity of our systems and technology. The failure of our systems and technology, or our disaster recovery and business continuity plans, to operate effectively could affect our ability to provide our products and services to customers, reduce efficiency, or cause delays in operations. Significant capital investments might be required to remediate any such problems. We are also dependent on our ongoing relationships with key technology providers, including provisioning of their services, products and technologies, and their ability to support those products and technologies. The inability of these providers to successfully provide and support those products could have an adverse impact on our business and results of operations.
 From time to time we upgrade, automate or otherwise transform our information systems, business processes, risk-based pricing system, and our system for evaluating risk. Certain information systems have been in place for a number of years and it has become increasingly difficult to support their operation. The implementation of technological and business process improvements, as well as their integration with customer and third-party systems when applicable, is complex, expensive and time consuming. If we fail to timely and successfully implement and integrate the new technology systems, if the third party providers upon which we are reliant do not perform as expected, if our legacy systems fail to operate as required, or if the upgraded systems and/or transformed and automated business processes do not operate as expected, it could have a material adverse impact on our business and results of operations.
 We could be materially adversely affected by a cybersecurity breach or failure of information security controls.
 As part of our business, we maintain large amounts of confidential and proprietary information both on our own servers and those of cloud computing services. This includes personal information of consumers and our employees. Personal information is subject to an increasing number of federal and state laws and regulations regarding privacy and data security, as well as contractual commitments. Any failure or perceived failure by us, or by the vendors with whom we share this information, to comply with such obligations may result in damage to our reputation, financial losses, litigation, increased costs, regulatory penalties or customer dissatisfaction.

 All information technology systems are potentially vulnerable to damage or interruption from a variety of sources, including by cyber attacks, such as those involving ransomware. We regularly defend against threats to our data and systems, including malware and computer virus attacks, unauthorized access, system failures and disruptions. Threats have the potential to jeopardize the information processed and stored in, and transmitted through, our computer systems and networks and otherwise cause interruptions or

 MGIC Investment Corporation 2024 Form 10-K | 34

 malfunctions in our operations, which could result in damage to our reputation, financial losses, litigation, increased costs, regulatory penalties or customer dissatisfaction. We could be similarly affected by threats against our vendors and/or third-parties with whom we share information.

 Globally, attacks are expected to continue accelerating in both frequency and sophistication with increasing use by actors of tools and techniques that may hinder our ability to identify, investigate and recover from incidents. The development and use of artificial intelligence ("AI") may increase our information security risks. For example, it may be more difficult to defend against cybersecurity breaches if AI is used to create attacks or bypass security measures. The relative newness of AI technology, and the lack of laws, regulations or standards governing its use may also increase the risk of misuse by us or by third parties with whom we do business. Cyber attacks may additionally increase as a result of retaliation by threat actors against actions taken by the U.S. and other countries in connection with wars and other global events. We operate under a hybrid workforce model and such model may be more vulnerable to security breaches.

 While we have information security policies and systems in place to secure our information technology systems and to prevent unauthorized access to or disclosure of sensitive information, there can be no assurance with respect to our systems and those of our third-party vendors that unauthorized access to the systems or disclosure of sensitive information, either through the actions of third parties or employees, will not occur. Due to our reliance on information technology systems, including ours and those of our customers and third-party service providers, and to the sensitivity of the information that we maintain, unauthorized access to the systems or disclosure of the information could adversely affect our reputation, severely disrupt our operations, result in a loss of business and expose us to material claims for damages and may require that we provide free credit monitoring services to individuals affected by a security breach.

 Should we experience an unauthorized disclosure of information or a cyber attack, including those involving ransomware, some of the costs we incur may not be recoverable through insurance, or legal or other processes, and this may have a material adverse effect on our results of operations.

 Our underwriting practices and the mix of business we write affects our Minimum Required Assets under the PMIERs, our premium yields and the likelihood of losses occurring.
 The Minimum Required Assets under the PMIERs are, in part, a function of the direct risk-in-force and the risk profile of the loans we insure, considering LTV ratio, credit score, vintage, Home Affordable Refinance Program ("HARP") status and delinquency status; and whether the loans were insured under lender-paid mortgage insurance policies or other policies that are not subject to automatic termination consistent with the Homeowners Protection Act requirements for borrower-paid mortgage insurance. Therefore, if our direct risk-in-force increases through increases in NIW, or if our mix of business changes to include loans with higher LTV ratios or lower FICO scores, for example, all other things equal, we will be required to hold more Available Assets in order to maintain GSE eligibility.
 Depending on the actual life of a single premium policy and its premium rate relative to that of a monthly premium policy, a single premium policy may generate more or less premium than a monthly premium policy over its life. The percentage of our NIW from all single premium policies was 2.4% in 2024. Beginning in 2012, the annual percentage of our NIW from single premium policies has been as low as 2.4% in 2024 and as high as 20.4% in 2015.
 As discussed in our risk factor titled "Reinsurance may be unavailable at current levels and prices, and/or the GSEs may reduce the amount of capital credit we receive for our reinsurance transactions," we have in place various QSR transactions. Although the transactions reduce our premiums, they have a lesser impact on our overall results, as losses ceded under the transactions reduce our losses incurred and the ceding commissions we receive reduce our underwriting expenses. The effect of the QSR transactions on the various components of pre-tax income will vary from period to period, depending on the level of ceded losses incurred. We also have in place various XOL reinsurance transactions under which we cede premiums. Under the XOL reinsurance transactions, for the respective reinsurance coverage periods, we retain the first layer of aggregate losses and the reinsurers provide second layer coverage up to the outstanding reinsurance coverage amount.
 In addition to the effect of reinsurance on our premiums, if credit performance remains strong and loss ratios remain low, we expect a decline in our in force portfolio yield over time as competition in the industry results in lower premium rates. Refinance transactions on single premium policies benefit the yield due to the impact of accelerated earned premium from cancellation prior to their estimated life. Recent low levels of refinance transactions have reduced that benefit.
 Our ability to rescind insurance coverage became more limited for new insurance written beginning in mid-2012, and it became further limited for new insurance written under our revised master policy that became effective March 1, 2020. These limitations may result in higher losses paid than would be the case under our previous master policies.
 From time to time, in response to market conditions, we change the types of loans that we insure. We also may change our underwriting guidelines, including by agreeing with certain approval recommendations from a GSE automated underwriting system. We also make exceptions to our underwriting requirements on a loan-by-loan basis and for certain customer programs. Our underwriting requirements are available on our website at

 MGIC Investment Corporation 2024 Form 10-K | 35

 Even when home prices are stable or rising, mortgages with certain characteristics have higher probabilities of claims. As of December 31, 2024, mortgages with these characteristics in our primary risk in force included mortgages with LTV ratios greater than 95% (17%), mortgages with borrowers having FICO scores below 680 (6%), including those with borrowers having FICO scores of 620-679 (6%), mortgages with limited underwriting, including limited borrower documentation (1%), and mortgages with borrowers having DTI ratios greater than 45% (or where no ratio is available) (20%). Each attribute is determined at the time of loan origination. Loans with more than one of these attributes accounted for 5% of our primary risk in force as of December 31, 2024, and 5% and 4% of our primary risk in force as of December 31, 2023 and December 31, 2022, respectively. When home prices increase, interest rates increase and/or the percentage of our NIW from purchase transactions increases, our NIW on mortgages with higher LTV ratios and higher DTI ratios may increase. Our NIW on mortgages with LTV ratios greater than 95% was 14% in 2024 and 12% in 2023. Our NIW on mortgages with DTI ratios greater than 45% was 29% in 2024 and 26% in 2023. Our NIW on mortgages with borrowers having FICO scores less than 680 was 4.0% in 2024 and 4.2% in 2023.

 From time to time, we change the processes we use to underwrite loans. For example: we rely on information provided to us by lenders that was obtained from certain of the GSEs' automated appraisal and income verification tools, which may produce results that differ from the results that would have been determined using different methods; we accept GSE appraisal waivers for certain loans; and we accept GSE appraisal flexibilities that allow property valuations in certain transactions to be based on appraisals that do not involve an onsite or interior inspection of the property. Our acceptance of automated GSE appraisal and income verification tools, GSE appraisal waivers and GSE appraisal flexibilities may affect our pricing and risk assessment. We also continue to further automate our underwriting processes and it is possible that our automated processes result in our insuring loans that we would have insured at a different premium rate or not otherwise have insured under our prior processes.
 Approximately 71% of our NIW during 2024 and 2023 was originated under delegated underwriting programs pursuant to which the loan originators had authority on our behalf to underwrite the loans for our mortgage insurance. For loans originated through a delegated underwriting program, we depend on the originators' compliance with our guidelines and rely on the originators' representations that the loans being insured satisfy the underwriting guidelines, eligibility criteria and other requirements. While we have established systems and processes to monitor whether certain aspects of our underwriting guidelines were being followed by the originators, such systems may not ensure that the guidelines were being strictly followed at the time the loans were originated.
 The widespread use of risk-based pricing systems by the private mortgage insurance industry (discussed in our risk factor titled "Competition or changes in our relationships with our customers could reduce our revenues, reduce our premium yields and / or increase our losses") makes it more difficult to compare our premium rates to those offered by our competitors. We may not be aware of industry rate changes until we observe that our mix of new insurance written has changed and our mix may fluctuate more as a result.
 In March 2024, the National Association of Realtors ("NAR") reached a settlement agreement to resolve a series of lawsuits against it. As part of the settlement, NAR now prohibits the requirement that home sellers, through the seller's agent commission structure, offer to pay the real estate brokerage fees of homebuyers' real estate agents in order to list for-sale properties on NAR-affiliated Multiple Listing Services. If the expense of the buyer's agent commission is shifted to the buyer, it may negatively impact the ability of the buyer to secure financing.
 The premiums we charge may not be adequate to compensate us for our liabilities for losses and as a result any inadequacy could materially affect our financial condition and results of operations.
 When we set our premiums at policy issuance, we have expectations regarding likely performance of the insured risks over the long term. Generally, we cannot cancel mortgage insurance coverage or adjust renewal premiums during the life of a policy. As a result, changes in economic conditions or the practices of the GSEs, higher than anticipated claims, or other unexpected events generally cannot be addressed by premium increases on policies in force or mitigated by our non-renewal or cancellation of insurance coverage. Our premiums are subject to approval by state regulatory agencies, which can delay or limit our ability to increase premiums on future policies. In addition, our customized rate plans may delay our ability to increase premiums on future policies covered by such plans. The premiums we charge, the investment income we earn and the amount of reinsurance we carry may not be adequate to compensate us for the risks and costs associated with the insurance coverage provided to customers. An increase in the number or size of claims, compared to what we anticipated when we set the premiums, could adversely affect our results of operations or financial condition. Our premium rates are also based in part on the amount of capital we are required to hold against the insured risk. If the amount of capital we are required to hold increases from the amount we were required to hold when we set the premiums, our returns may be lower than we assumed. For a discussion of the amount of capital we are required to hold, see our risk factor titled "We may not continue to meet the GSEs' private mortgage insurer eligibility requirements and our returns may decrease if we are required to maintain more capital in order to maintain our eligibility."
 If state or federal regulations or statutes are changed in ways that ease mortgage lending standards and/or requirements, or if lenders seek ways to replace business in times of lower mortgage originations, it is possible that more mortgage loans could be originated with higher risk characteristics than are currently being originated, such as loans with lower FICO scores and higher DTI ratios. The focus of the FHFA leadership on increasing homeownership opportunities for borrowers is likely to have this effect. Lenders could pressure mortgage insurers to insure such loans, which are expected to experience higher claim rates. Although we attempt to incorporate these higher expected claim rates into our underwriting and pricing models, there can be no assurance that the premiums earned and the associated investment income will be adequate to compensate for actual losses paid even under our current underwriting requirements.

 MGIC Investment Corporation 2024 Form 10-K | 36

 Actual or perceived instability in the financial services industry or non-performance by financial institutions or transactional counterparties could materially impact our business.
 Limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions, transactional counterparties or other companies in the financial services industry with which we do business, or concerns or rumors about the possibility of such events, have in the past and may in the future lead to market-wide liquidity problems. Such conditions may negatively impact our results and/or financial condition. While we are unable to predict the full impact of these conditions, they may lead to among other things: disruption to the mortgage market, delayed access to deposits or other financial assets; losses of deposits in excess of federally-insured levels; reduced access to, or increased costs associated with, funding sources and other credit arrangements adequate to finance our current or future operations; increased regulatory pressure; the inability of our counterparties and/or customers to meet their obligations to us; economic downturn; and rising unemployment levels. Refer to our risk factor titled "Downturns in the domestic economy or declines in home prices may result in more homeowners defaulting and our losses increasing, with a corresponding decrease in our returns" for more information about the potential effects of a deterioration of economic conditions on our business.
 We routinely execute transactions with counterparties in the financial services industry, including commercial banks, brokers and dealers, investment banks, reinsurers, and our customers. Many of these transactions expose us to credit risk and losses in the event of a default by a counterparty or customer. Any such losses could have a material adverse effect on our financial condition and results of operations.
 We rely on our management team and our business could be harmed if we are unable to retain qualified personnel or successfully develop and/or recruit their replacements.
 Our success depends, in part, on the skills, working relationships and continued services of our management team and other key personnel. The unexpected departure of key personnel could adversely affect the conduct of our business. In such event, we would be required to obtain other personnel to manage and operate our business. In addition, we will be required to replace the knowledge and expertise of our aging workforce as our workers retire. In either case, there can be no assurance that we would be able to develop or recruit suitable replacements for the departing individuals; that replacements could be hired, if necessary, on terms that are favorable to us; or that we can successfully transition such replacements in a timely manner. We currently have not entered into any employment agreements with our officers or key personnel. Volatility or lack of performance in our stock price may affect our ability to retain our key personnel or attract replacements should key personnel depart. Without a properly skilled and experienced workforce, our costs, including productivity costs and costs to replace employees may increase, and this could negatively impact our earnings.
 Competition or changes in our relationships with our customers could reduce our revenues, reduce our premium yields and / or increase our losses.
 The mortgage insurance industry is highly competitive and is expected to remain so. Our competitors primarily include other private mortgage insurers and governmental agencies, principally the FHA and VA. We believe we currently compete with other private mortgage insurers based on premium rates, underwriting requirements, financial strength (including based on credit or financial strength ratings), customer relationships, name recognition, reputation, strength of management teams and field organizations, the ancillary products and services provided to lenders, and the effective use of technology and innovation in the delivery and servicing of our mortgage insurance products. Recently reported increases in the credit quality of borrowers, and the relative financial results of the existing mortgage insurance companies, may encourage new entrants into the private mortgage insurance industry, which could further increase competition in our business. Changes in the competitive landscape, including as a result of new market entrants, may adversely impact our results.
 Our relationships with our customers, which may affect the amount of our NIW, could be adversely affected by a variety of factors, including if our premium rates are higher than those of our competitors, our underwriting requirements are more restrictive than those of our competitors, our customers are dissatisfied with our claims-paying practices (including insurance policy rescissions and claim curtailments), or the availability of alternatives to mortgage insurance.
 In recent years, pricing has become a key competitive factor in the private mortgage insurance market, with an increasing number of customers prioritizing the lowest premium rate available for any particular loan. The industry has materially reduced its use of standard rate cards, which were fairly consistent among competitors, and correspondingly increased its use of (i) pricing systems that use a spectrum of filed rates to allow for formulaic, risk-based pricing based on multiple attributes that may be quickly adjusted within certain parameters, and (ii) customized rate plans pursuant to which rates may be available to customers for a defined period of time. The widespread use of risk-based pricing systems by the private mortgage insurance industry makes it more difficult to compare our rates to those offered by our competitors. We may not be aware of industry rate changes until we observe that our volume of NIW has changed. In addition, business under customized rate plans is awarded by certain customers for only limited periods of time. As a result, our NIW may fluctuate more than it had in the past. Failure to maintain our business relationships and business volumes with our largest customers could materially impact our business. Regarding the concentration of our new business, our top ten customers accounted for approximately 37% in the twelve months ended December 31, 2024 and December 31, 2023, respectively.
 We monitor various competitive and economic factors while seeking to balance both profitability and market share considerations in developing our pricing strategies. Our premium yield is expected to decline over time as older insurance policies with premium rates that are generally higher run off and new insurance policies with premium rates that are generally lower remain on our books.

 MGIC Investment Corporation 2024 Form 10-K | 37

 Additionally, technological advancements and innovation are occurring at a rapid pace that may continue to accelerate. Our competitive position could be impacted if we are unable to utilize, in a cost effective and competitive manner, technology such as AI and machine learning that collects and analyzes data to inform underwriting or other decisions, or if our competitors collect and use data which we do not have the ability to access or use. Changes in technology related to collection and application of data could expose us to regulatory or legal actions and may have a material adverse effect on our business, reputation, results of operations and financial condition.
 Certain of our competitors have access to capital at a lower cost than we do (including, through off-shore intercompany reinsurance vehicles, which have tax advantages that may increase if U.S. corporate income taxes increase). As a result, they may be able to achieve higher after-tax rates of return on their NIW compared to us, which could allow them to leverage reduced premium rates to gain market share, and they may be better positioned to compete outside of traditional mortgage insurance, including by participating in alternative forms of credit enhancement pursued by the GSEs discussed in our risk factor titled "The amount of insurance we write could be adversely affected if lenders and investors select alternatives to private mortgage insurance or are unable to obtain capital relief for mortgage insurance."
 Adverse rating agency actions could have a material adverse impact on our business, results of operations and financial condition.
 Financial strength ratings, which various rating agencies publish as independent opinions of an insurer's financial strength and ability to meet ongoing insurance and contract obligations, are important to maintaining public confidence in our mortgage insurance coverage and our competitive position. PMIERs requires approved insurers to maintain at least one rating with a rating agency acceptable to the respective GSEs. Downgrades in our financial strength ratings could materially affect our business and results of operations, including in the ways described below:

 • Our failure to maintain a rating acceptable to the GSEs could impact our eligibility as an approved insurer under PMIERs.
 • A downgrade in our financial strength ratings could result in increased scrutiny of our financial condition by the GSEs and/or our customers, potentially resulting in a decrease in the amount of our NIW.
 • If we are unable to compete effectively in the current or any future markets as a result of the financial strength ratings assigned to our insurance subsidiaries, our future NIW could be negatively affected.
 • Our ability to participate in the non-GSE residential mortgage-backed securities market (the size of which has been limited since 2008, but may grow in the future), could depend on our ability to maintain and improve our investment grade ratings for our insurance subsidiaries. We could be competitively disadvantaged with some market participants because the financial strength ratings of our insurance subsidiaries are lower than those of some competitors. MGIC's financial strength rating from A.M. Best is A (with a stable outlook), from Moody's is A3 (with a positive outlook) and from Standard & Poor's is A- (with a stable outlook).
 • Financial strength ratings may also play a greater role if the GSEs no longer operate in their current capacities, for example, due to legislative or regulatory action. In addition, although the PMIERs do not require minimum financial strength ratings, the GSEs consider financial strength ratings to be important when using forms of credit enhancement other than traditional mortgage insurance, as discussed in our risk factor titled "The amount of insurance we write could be adversely affected if lenders and investors select alternatives to private mortgage insurance or are unable to obtain capital relief for mortgage insurance." The final GSE capital framework provides more capital credit for transactions with higher rated counterparties, as well as those who are diversified. Although we are currently unaware of a direct impact on MGIC, this could potentially become a competitive disadvantage in the future.
 • Downgrades to our ratings or the ratings of our mortgage insurance subsidiary could adversely affect our cost of funds, liquidity, and access to capital markets.
 We are subject to the risk of legal proceedings.
 We operate in a highly regulated industry that is subject to the risk of litigation and regulatory proceedings, including related to our claims paying practices. From time to time, we are a party to material litigation and are also subject to legal and regulatory claims, assertions, actions, reviews, audits, inquiries and investigations. Additional lawsuits, legal and regulatory proceedings and inquiries or other matters may arise in the future. The outcome of future legal and regulatory proceedings, inquiries or other matters could result in adverse judgments, settlements, fines, injunctions, restitutions or other relief which could require significant expenditures or have a material adverse effect on our business, results of operations and financial condition. See our risk factor titled "We are subject to comprehensive regulation and other requirements, which we may fail to satisfy" for additional information about risks related to government enforcement actions.
 From time to time, we are involved in disputes and legal proceedings in the ordinary course of business. In our opinion, based on the facts known at this time, the ultimate resolution of these ordinary course disputes and legal proceedings will not have a material adverse effect on our financial condition or results of operations. Under ASC 450-20, until a loss associated with settlement discussions or legal proceedings becomes probable and can be reasonably estimated, we do not accrue an estimated loss. When we determine that a loss is probable and can be reasonably estimated, we record our best estimate of our probable loss. In those cases, until settlement negotiations or legal proceedings are concluded it is possible that we will record an additional loss.

 Our success depends, in part, on our ability to manage risks in our investment portfolio.
 Our investment portfolio is an important source of revenue and is our primary source of claims paying resources. Although our investment portfolio consists mostly of high quality, investment-grade fixed income investments, our investment portfolio is affected by general economic conditions and tax policy, which may adversely affect the markets for credit and interest-rate-sensitive securities, including the extent and timing of investor participation in these markets, the level and volatility of interest rates and credit spreads and, consequently, the value of our fixed income securities. Prevailing market rates have increased for various reasons, including inflationary pressures, which has reduced the fair value of our investment portfolio holdings relative to their amortized cost. The value of our investment portfolio may also be adversely affected by ratings downgrades, increased bankruptcies, and credit spreads widening. In addition, the collectability and valuation of our municipal bond portfolio may be adversely affected by budget deficits, and declining tax bases and revenues experienced by state and local municipalities. Our investment portfolio also includes commercial mortgage-backed securities, collateralized loan obligations, and asset-backed securities, which could be adversely affected by declines in real estate valuations, increases in unemployment, geopolitical risks and/or financial market disruption, including more restrictive lending conditions and a heightened collection risk on the underlying loans. As a result of these matters, we may not achieve our investment objectives and a reduction in the market value of our investments could have an adverse effect on our liquidity, financial condition and results of operations.

 We carry certain financial instruments at fair value and disclose the fair value of all financial instruments. Valuations use inputs and assumptions that are not always observable or may require estimation; valuation methods may be complex and may also require estimation, thereby resulting in values that are less certain and may vary significantly from the value at which the investments may be ultimately sold. For additional information about the methodologies, estimates and assumptions we use in determining the fair value of our investments refer to Note 3 of Item 8 in Part II our Annual Report on Form 10-K for the year ended December 31, 2023 - "Fair Value Measurements."

 Federal budget deficit concerns and the potential for political conflict over the U.S. government's debt limit may increase the possibility of a default by the U.S. government on its debt obligations, related credit-rating downgrades, or an economic recession in the United States. Many of our investment securities are issued by the U.S. government and government agencies and sponsored entities. As a result of uncertain domestic political conditions, including potential future federal government shutdowns, the possibility of the federal government defaulting on its obligations due to debt ceiling limitations or other unresolved political issues, investments in financial instruments issued or guaranteed by the federal government pose liquidity risks. Any potential downgrades by rating agencies in long-term sovereign credit ratings, as well as sovereign debt issues facing the governments of other countries, could have a material adverse impact on financial markets and economic conditions worldwide.

 For the significant portion of our investment portfolio that is held by MGIC, to receive full capital credit under insurance regulatory requirements and under the PMIERs, we generally are limited to investing in investment grade fixed income securities whose yields reflect their lower credit risk profile. Our investment income depends upon the size of the portfolio and its reinvestment at prevailing interest rates. A prolonged period of low investment yields would have an adverse impact on our investment income as would a decrease in the size of the portfolio.
 We structure our investment portfolio to satisfy our expected liabilities, including claim payments in our mortgage insurance business. If we underestimate our liabilities or improperly structure our investments to meet these liabilities, we could have unexpected losses resulting from the forced liquidation of fixed income investments before their maturity, which could adversely affect our results of operations.
 The inability of our insurance subsidiaries to pay dividends in sufficient amounts would harm our ability to meet our obligations, pay future shareholder dividends and/or make future share repurchases.
 MGIC Investment Corporation is the holding company for our insurance operating subsidiaries. At the holding company level, our principal assets are the shares of capital stock of our insurance company subsidiaries and cash and investments. Dividends and other permitted distributions from MGIC are the holding company's primary source of funds used to meet ongoing cash requirements, including future debt service payments, repurchases of its shares, payment of dividends to our shareholders, and other expenses. Other sources of holding company cash inflow include investment income and raising capital in the public markets. The payment of dividends from MGIC is subject to regulatory approval as described in our Annual Reports on Form 10-K. In general, dividends in excess of prescribed limits are deemed "extraordinary" and may not be paid if disapproved by the OCI. The prescribed limits are based on a rolling 12-month period, and as such, the impact of the limitations will vary over time. In the twelve months ended December 31, 2024, MGIC paid $750 million in dividends to the holding company. Future dividend payments from MGIC to the holding company will be determined in consultation with the Board of Directors, and after considering any updated estimates about our business, subject to regulatory approval.

 The long-term debt obligations are owed by the holding company and not its subsidiaries. At December 31, 2024, we had approximately $1.1 billion in cash and investments at our holding company and our holding company's long-term debt obligations were $650 million in aggregate principal amount. Annual debt service on the long-term debt obligations outstanding as of December 31, 2024, is approximately $34 million. The inability of MGIC to pay dividends (or other intercompany amounts due) in an amount sufficient to enable us to meet our cash requirements at the holding company level could have an adverse effect on our operations, and our ability to repay debt, repurchase shares and/or pay dividends to shareholders.

 MGIC Investment Corporation 2024 Form 10-K | 39

 If any capital contributions to our subsidiaries are required, such contributions would decrease our holding company cash and investments.
 Your ownership in our company may be diluted by additional capital that we raise.
 As noted above under our risk factor titled "We may not continue to meet the GSEs' private mortgage insurer eligibility requirements and our returns may decrease if we are required to maintain more capital in order to maintain our eligibility," although we are currently in compliance with the requirements of the PMIERs, there can be no assurance that we would not seek to issue additional debt capital or to raise additional equity or equity-linked capital to manage our capital position under the PMIERs or for other purposes. Any future issuance of equity securities may dilute your ownership interest in our company. In addition, the market price of our common stock could decline as a result of sales of a large number of shares or similar securities in the market or the perception that such sales could occur.
 The price of our common stock may fluctuate significantly, which may make it difficult for holders to resell common stock when they want or at a price they find attractive.
 The market price for our common stock may fluctuate significantly. In addition to the risk factors described herein, the following factors may have an adverse impact on the market price for our common stock: changes in general conditions in the economy or the housing market, the mortgage insurance industry or the financial stability of markets and financial services industry; announcements by us or our competitors of acquisitions or strategic initiatives; our actual or anticipated quarterly and annual operating results; changes in expectations of future financial performance (including incurred losses on our insurance in force); changes in estimates of securities analysts or rating agencies; actual or anticipated changes in our share repurchase program or dividends; changes in operating performance or market valuation of companies in the mortgage insurance industry; the addition or departure of key personnel; failure to establish and maintain effective internal controls over financial reporting, changes in tax law; and adverse press or news announcements affecting us or the industry. In addition, ownership by certain types of investors may affect the market price and trading volume of our common stock. For example, ownership in our common stock by investors such as index funds and exchange-traded funds can affect the stock's price when those investors must purchase or sell our common stock because the investors have experienced significant cash inflows or outflows, the index to which our common stock belongs has been rebalanced, or our common stock is added to and/or removed from an index (due to changes in our market capitalization, for example).

 None.

 Item 1C. Cybersecurity
 RISK MANAGEMENT AND STRATEGY
 MGIC's Information Security Program (ISP) includes information security policies, annual risk assessments and analyses, threat monitoring and alerting, vulnerability management, incident response, and data loss prevention controls. With the ISP, MGIC seeks to prevent, detect, and respond to unauthorized access, use, or disclosure of confidential information.

 MGIC's Information Risk Management (IRM) team is responsible for safeguarding the organization's information assets, data, and technology infrastructure from security threats and vulnerabilities. The IRM team's primary focus is the protection of the confidentiality, integrity, and availability of sensitive information and compliance with relevant laws, regulations, and industry standards. The IRM team is overseen by the Company's Chief Information Security Officer (CISO).

 Our ISP is benchmarked against the National Institute of Standards and Technology (NIST) Cybersecurity Framework. Additionally, various aspects of the ISP are subject to periodic audit by the Company's Internal Audit department or third-party professionals engaged by the Internal Audit department. Such audits vary from year-to-year but are generally focused on compliance with stated control activities, standards, and internal policies, as well as maintaining the integrity and independence of the audit process. Cybersecurity risk reviews such as SOC2, SOX controls, penetration tests, and regulatory controls are conducted by independent third parties.

 The ISP also incorporates a vendor due diligence process that is designed to assess vendor control environments and evaluate risks associated with vendor access to the Company's confidential data and systems. The process includes assessing and managing the cyber risks associated with engaging third-party vendors and reviewing their information security practices.

 In the event of a suspected or threatened cybersecurity incident, the CISO determines whether to activate the Company's Cyber Incident Response Team ("CIRT"), composed of different subject matter experts from applicable domains such as network, infrastructure, and application areas in order to evaluate the technical issues relative to the incident. The CIRT is overseen by the CISO. If necessary, the CIRT may engage third-party cybersecurity experts to evaluate and/or remediate the incident. If and when the CIRT is activated, the CISO will inform the Company's Chief Information Officer (CIO). In the event that the CIRT confirms that the incident relates to a cybersecurity incident or compromise of MGIC's computer systems, the CISO will notify the General Counsel, who will advise the Chief Executive Officer ("CEO"), who is a member of the Board of Directors. In addition to advising the CEO, the General Counsel will also convene an established committee whose members include the General Counsel, Chief Financial and Risk Officer, Senior Vice President of Investor Relations, and Chief Accounting Officer in order to determine if the event is a material cybersecurity incident so as to trigger an Item 1.05 filing on Form 8-K. If a determination is made that the event is material, or if the CEO or General Counsel otherwise determines it advisable, the CEO or General Counsel, or a delegate thereof, shall notify the Chairman of the Board, Lead Independent Director, and Chairpersons of the Board's Business Technology and Transformation Committee (the "BTTC") and Audit Committee.

 To our knowledge, during the reporting period there were no cybersecurity incidents that materially affected or are reasonably likely to materially affect our business strategies, results of operations, or financial condition. For additional information about risks related to cybersecurity, see our risk factors titled "Information technology system failures or interruptions may materially impact our operations and/or adversely affect our financial results" and "We could be materially adversely affected by a cybersecurity breach or failure of information security controls."

 GOVERNANCE
 The CISO reports to the CIO and partners with the Company's Risk, Audit, Legal and Compliance Departments to promote alignment of cybersecurity risk management strategy with the broader risk management strategy for the organization. The integration of information security into the overall enterprise risk management framework enables collaboration on the identification, assessment, mitigation and monitoring of cybersecurity risks that have the potential to materially impact the operation of the Company.

 The Risk Management Committee of the Board coordinates with the Board and other Board committees regarding the assignment to the Board and Committees of oversight responsibilities for all identified key risks to the Company. Risks related to cybersecurity are overseen by the BTTC. The BTTC monitors cybersecurity risks associated with both internal and external actors, including third-party vendors and service providers. Additional information about the BTTC's role in overseeing risks related to cybersecurity and information technology generally can be found in the Committee's Charter at mtg.mgic.com/corporate-governance/highlights.

 The CISO provides quarterly updates about the Company's cybersecurity program to the BTTC. Updates may include topics such as management's efforts to identify and monitor risks, investments to improve the Company's detection and response systems, the results of risk assessments, compliance with controls, vendor oversight, strategic technology planning, and if necessary, the status of any new, ongoing, or prior cybersecurity incident. The CISO also periodically attends the BTTC meetings; the CIO regularly attends the meetings.

 SUMMARY OF 2024 FINANCIAL RESULTS
 Net income for 2024 was $763.0 million (2023: $712.9 million) and diluted income per share was $2.89 (2023: $2.49). The increase in net income is primarily due to an increase in investment income, net of expenses, an increase in net premiums earned, and a decrease in other underwriting and operating expenses, net. This was partially offset by an increase in losses incurred, net and an increase in our provision for income taxes. Diluted income per share increased primarily due to an increase in net income and a decrease in the number of diluted weighted average shares outstanding.

 Adjusted net operating income for 2024 was $768.5 million (2023: $724.4 million) and adjusted net operating income per diluted share was $2.91 (2023: $2.53). The increase in adjusted net operating income in 2024 compared to 2023 is primarily due to an increase in net income. The increase in 2024 adjusted net operating income per diluted share compared to 2023 is primarily due to an increase in adjusted net operating income and a decrease in the number of diluted weighted average shares outstanding.

 Premiums earned for 2024 were $970.8 million, compared with $952.6 million in the prior year. The increase in premiums earned compared with the prior year is primarily due to a decrease in ceded premiums.

 Net investment income in 2024 was $244.6 million, compared with $214.7 million in the prior year. The increase in net investment income was due to an increase of 42 basis points in the average investment yield.

 Losses incurred, net were $(14.9) million, compared with $(20.9) million in the prior year. While new delinquency notices added $197.6 million to losses incurred in 2024, our re-estimation of loss reserves on previously received delinquency notices resulted in favorable development of $212.5 million. For the year ended December 31, 2023, new delinquency notices added approximately $187.7 million, our re-estimation of loss reserves on previously received delinquency notices resulted in favorable development of $208.5 million. The favorable development for both periods primarily resulted from a decrease in the expected claim rate on previously received delinquencies. Home price appreciation in recent years has allowed some borrowers to cure their delinquencies through the sale of their property.

 Underwriting and other expenses, net were $209.3 million, compared to $226.0 million in the prior year. The decrease in underwriting and other expenses, net was primarily due to a decrease in pension expenses and a decrease in expenses related to professional and consulting services. Pension expenses were higher in 2023 due to settlement accounting charges.

 MGIC Investment Corporation 2024 Form 10-K | 47

 Our provision for income taxes increased to $205.7 million in 2024 compared to $189.3 million in 2023 primarily due to an increase in income before tax. Our effective tax rate for 2024 was 21.2% compared to 21.0% for 2023.

 BUSINESS ENVIRONMENT
 Economic conditions
 Mortgage originations increased in 2024 compared to 2023, reflecting an increase in refinance volumes, attributed to a brief decline in interest rates during 2024, while purchase origination activity remained relatively flat.

 The level of interest rates and home prices may change in the future. For information about the possible effects of such changes, see our risk factors titled "If the volume of low down payment home mortgage originations declines, the amount of insurance that we write could decline," and "Downturns in the domestic economy or declines in home prices may result in more homeowners defaulting and our losses increasing, with a corresponding decrease in our returns."

 Mortgage insurance market
 The strong credit quality of our insurance portfolio reflects several years of favorable housing fundamentals, and in our view, generally favorable risk characteristics on our recently insured loans. Our insurance in force increased during the year as a result of an increase in NIW offset partially by cancellations.

 The percentage of our NIW with DTI ratios over 45% and LTVs over 95% will fluctuate based on the mortgage conditions such as the percentage of NIW from purchase transactions, changes in home prices, changes in interest rates, and GSE activities. Refer to "Mortgage Insurance Portfolio" for information on our NIW mix during 2024.
 Competition
 PMI
 The private mortgage insurance industry is highly competitive and is expected to remain so. Our competitors primarily include other private mortgage insurers and governmental agencies, principally the FHA and VA. We believe that we currently compete with other private mortgage insurers based on premium rates, underwriting requirements, financial strength (including based on credit or financial strength ratings), customer relationships, name recognition, reputation, strength of management teams and field organizations, and the effective use of technology and innovation in the delivery and servicing of our mortgage insurance products.

 Pricing practices
 In recent years, pricing has become a key competitive factor in the private mortgage insurance market, with an increasing number of customers prioritizing the lowest premium rate available for any particular loan. The industry has materially reduced its use of standard rate cards, which were fairly consistent among competitors, and correspondingly increased its use of (i) "risk-based pricing systems" that use a spectrum of filed rates to allow for formulaic, risk-based pricing based on multiple attributes that may be quickly adjusted within certain parameters, and (ii) customized rate plans pursuant to which rates may be available to customers for a defined period of time. We monitor various competitive and economic factors while seeking to balance both profitability and market share considerations in developing our pricing strategies.

 For information about competition in the private mortgage insurance industry, see our risk factor titled "Competition or changes in our relationships with our customers could reduce our revenues, reduce our premium yields and/or increase our losses" in Item 1A.

 In 2018, the GSEs initiated secondary mortgage market programs with loan level mortgage default coverage provided by various (re)insurers that are not mortgage insurers governed by PMIERs, and that are not selected by the lenders. These programs, which currently account for a small percentage of the low down payment market, compete with traditional private mortgage insurance and, due to differences in policy terms, they may offer premium rates that are below prevalent single premium lender-paid mortgage insurance ("LPMI") rates. We participate in these programs from time to time.
 The GSEs (and other investors) have also used other forms of credit enhancement that did not involve traditional private mortgage insurance, such as engaging in credit-linked note transactions executed in the capital markets, or using other forms of debt issuances or securitizations that transfer credit risk directly to other investors, including competitors and an affiliate of MGIC; using other risk mitigation techniques in conjunction with reduced levels of private mortgage insurance coverage; or accepting credit risk without credit enhancement. For information about the various business practices of the GSEs that may be changed, including through expansion or modification of these programs, see our risk factor titled "Changes in the business practices of Fannie Mae and Freddie Mac ("the GSEs"), federal legislation that changes their charters or a restructuring of the GSEs could reduce our revenues or increase our losses" in Item 1A.

 Government programs
 PMI also competes against government mortgage insurance programs such as the FHA, VA, and USDA, primarily for lower FICO score business. The combined market share of primary mortgage insurance written by government programs continues to exceed that written by PMI in both 2024 and 2023.

 Refer to "Mortgage Insurance Portfolio" for additional discussion on market share and our operating measures including NIW, IIF and RIF.

 PMIERs
 We operate under the requirements of the PMIERs of the GSEs in order to insure loans delivered to or purchased by them. The PMIERs include financial requirements as well as business, quality control and certain transactional approval requirements. The financial requirements of the PMIERs require a mortgage insurer's "Available Assets" (generally only the most liquid assets of an insurer) to equal or exceed its "Minimum Required Assets" (which are based on an insurer's book of risk in force, calculated from tables of factors with several risk dimensions, reduced for credit given for risk ceded under reinsurance transactions, and subject to a floor amount). Based on our application of PMIERs, MGIC's Available Assets under PMIERs totaled $5.8 billion, an excess of $2.2 billion over its Minimum Required Assets at December 31, 2024.

 BUSINESS OUTLOOK FOR 2025
 Our outlook for 2025 should be viewed against the backdrop of the business environment discussed above.

 NIW
 Our NIW is affected by total mortgage originations, the percentage of total mortgage originations using private mortgage insurance (the "PMI penetration rate"), and our market share within the PMI industry. As of January 2025, the total average mortgage origination forecasts from Fannie Mae and the MBA indicate mortgage originations of $2.0 trillion in 2025, compared to an estimated $1.7 trillion in 2024. Both purchase originations and refinance transactions are forecasted to increase in 2025 when compared to 2024. We are expecting NIW to increase slightly in 2025 compared to 2024.

 The widespread use of risk based pricing systems by the PMI industry makes it more difficult to compare our rates to those offered by our competitors. We may not be aware of industry rate changes until we observe that our volume of NIW has changed. In addition, business under customized rate plans is awarded by certain customers for only limited periods of time. As a result, our NIW may fluctuate more than it had in the past.

 IIF
 Our IIF increased 0.6% in 2024 and is expected to remain relatively flat in 2025. Our book of IIF is an important driver of our future revenues, and its growth is driven by our ability to generate NIW and the retention of our IIF, as measured by our Annual persistency. Interest rates influence both our NIW and persistency. Generally speaking, in a rising rate environment, total mortgage originations may decline; however, we would also expect policy cancellation rates to decline, and in turn increase Annual persistency, although the impact generally lags the change in interest rates. As of January 2025, forecasts from Fannie Mae and the MBA indicate a modest decrease in interest rates in 2025 compared to 2024 and the slowdown in the rate of home price appreciation.

 Results of operations
 Premiums
 Our direct premiums written and earned are impacted by our IIF during the period and our in force premium yield. We expect our in force portfolio premium yield to remain relatively flat in 2025 and we expect our net premiums written and earned to decrease in 2025, driven by an increase in ceded premiums. Premiums earned are also impacted by the amount of accelerated premiums from single premium policy cancellations, which generally decrease as refinance activity decreases. Our unearned premium decreased to $120.4 million at December 31, 2024 from $157.8 million at December 31, 2023.

 Our net premiums written and earned are primarily impacted by the changes in the direct premiums written and earned noted above and by the amount of premiums we cede under our quota share and excess of loss reinsurance transactions. The amount of premiums we cede in 2025 will be affected by any changes in our reinsurance coverage. Premiums we cede under our quota share transactions are also impacted by the profit commission we receive. The amount of profit commission is variable year-to-year and is dependent on the amount of losses incurred ceded. Increases in ceded losses incurred will benefit our losses incurred line, but will result in lower profit commission and higher ceded premiums.

 Factors that affect the amount of premiums we earn from our IIF are further discussed in our "Consolidated Results of Operations - Premium yield."

 Investment income
 Net investment income is a material contributor to our results of operations. We expect net investment income in 2025 to be relatively flat in comparison to 2024. The amount of investment income will be impacted by the change in the yield we can earn on investments

 MGIC Investment Corporation 2024 Form 10-K | 49

 and the level of invested assets. The level of invested assets will primarily be impacted by the amount of cash we expect to use in financing activities relative to our cash from operations. The magnitude of any change in our invested asset level will be subject to the timing of our financing activities.

 Losses
 Losses incurred, net is impacted by the level of new delinquency notices. Generally, on our primary business, the highest claim frequency years have been the third and fourth year after loan origination. As of December 31, 2024, 50% of our primary RIF was written subsequent to December 31, 2021, 74% of our primary RIF was written subsequent to December 31, 2020, and 87% of our primary RIF was written subsequent to December 31, 2019. The pattern of claim frequency can be affected by many factors, including annual persistency and deteriorating economic conditions. Home price appreciation in recent years has allowed some borrowers to cure their delinquencies through the sale of their property. In addition, an increase in third party property sales prior to claim settlement has resulted in a decrease in the average claim paid on the claims we do receive. We expect net losses and LAE paid to increase; however, the magnitude and timing of the increases are uncertain.

 Underwriting and operating expenses, net
 We expect underwriting and operating expenses, net to be modestly lower in 2025 compared to 2024.

 Income taxes
 We expect a modest decrease in our effective tax rate in 2025 compared to 2024 due to purchases of transferable federal tax credits.

 CAPITAL
 MGIC dividend payments to our holding company
 The ability of MGIC to pay dividends is restricted by insurance regulation. Amounts in excess of prescribed limits are deemed "extraordinary" and may not be paid if disapproved by the OCI. A dividend is extraordinary when the proposed dividend amount, plus dividends paid in the twelve months preceding the dividend payment date exceed the ordinary dividend level. In 2025, MGIC can pay $97 million of ordinary dividends without OCI approval, before taking into consideration dividends paid in the preceding twelve months. In 2024 and 2023, MGIC paid a cash and/or investment security dividend of $750 million and $600 million, respectively, to our holding company. Future dividend payments from MGIC to the holding company will continue to be determined in consultation with the Board of Directors.

 Dividends to shareholders
 In the first and second quarters of 2024, we paid quarterly cash dividends of $0.115 per share to shareholders which totaled $63.3 million. In the third and fourth quarters of 2024, we paid quarterly cash dividends of $0.13 per share which totaled $67.8 million. On January 28, 2025, the Board of Directors declared a quarterly cash dividend to holders of the company's common stock of $0.13 per share payable on March 5, 2025, to shareholders of record at the close of business on February 18, 2025. We expect to continue to make dividend payments to shareholders in 2025.

 Share repurchase programs
 Repurchases may be made from time to time on the open market (including through 10b5-1 plans) or through privately negotiated transactions. The repurchase programs may be suspended for periods or discontinued at any time. We repurchased approximately 25.3 million shares in 2024 for $566.6 million. In 2023, we repurchased approximately 21.7 million shares of our common stock for $340.6 million of holding company resources. In 2025, we expect share repurchase programs will remain our primary means of returning capital to shareholders.

 The following table shows details of our share repurchase program.

 December 31, 2026

 As of December 31, 2024, we had approximately 248.4 million shares of common stock outstanding which was a decrease of 8.8% from December 31, 2023.

 GSEs
 We must comply with a GSE's PMIERs to be eligible to insure loans delivered to or purchased by that GSE. The PMIERs include financial requirements, as well as business, quality control and certain transaction approval requirements. The PMIERs provide that the GSEs may amend any provision of the PMIERs or impose additional requirements with an effective date specified by the GSEs. MGIC is in compliance with the PMIERs and eligible to insure loans purchased by the GSEs. In August 2024, the GSEs issued updates to the calculation of Available Assets.

 The financial requirements of the PMIERs require a mortgage insurer's "Available Assets" (generally only the most liquid assets of an insurer) to equal or exceed its "Minimum Required Assets" (which are generally based on an insurer's book of risk in force and

 MGIC Investment Corporation 2024 Form 10-K | 50

 calculated from tables of factors with several risk dimensions, reduced for credit given for risk ceded under reinsurance agreements, and subject to a floor amount). Based on our interpretation of the PMIERs as of December 31, 2024, MGIC's Available Assets totaled $5.8 billion, or $2.2 billion in excess of its Minimum Required Assets. The update will be implemented through a 24-month phased-in approach, with a fully effective date of September 30, 2026. If these changes were effective as of December 31, 2024, without a graduated implementation period, MGIC's Available Assets of $5.8 billion would decrease by approximately 1% or $50 million, and MGIC's PMIERs excess would be $2.1 billion.

 The PMIERs generally require us to hold significantly more Minimum Required Assets for delinquent loans than for performing loans and the Minimum Required Assets required to be held increases as the number of payments missed on a delinquent loan increases.

 Our reinsurance transactions enable us to earn higher returns on our Minimum Required Assets than we would without them because they generally reduce the Minimum Required Assets we must hold under PMIERs. However, reinsurance may not always be available to us, or available only on terms, or costs, that we find unacceptable.

 The calculated credit for XOL Transactions under PMIERs is generally based on the PMIERs requirement of the covered loans and the attachment and detachment point of the coverage. PMIERs credit is generally not given for the reinsured risk above the PMIERs requirement. Our existing reinsurance transactions are subject to periodic review by the GSEs and there is a risk we will not receive our current level of credit in future periods for the risk ceded under them. In addition, we may not receive the same level of credit under future transactions that we receive under existing transactions. If MGIC is not allowed certain levels of credit under the PMIERs, under certain circumstances, MGIC may terminate the reinsurance transactions without penalties.

 For additional information about our reinsurance transactions, see our risk factor titled "Reinsurance may be unavailable at current levels and prices, and/or the GSEs may reduce the amount of capital credit we receive for our reinsurance transactions." in Item 1A.

 GSE Reform
 The FHFA has been the conservator of the GSEs since 2008 and has the authority to control and direct their operations. Given that the Director of the FHFA is removable by the President at will, the agency's agenda, policies and actions are influenced by the current administration. The increased role that the federal government has assumed in the residential housing finance system through the GSE conservatorships may increase the likelihood that the business practices of the GSEs change, including through administration changes and actions. Such changes could have a material adverse effect on us.

 It is uncertain what role the GSEs, FHA and private capital, including private mortgage insurance, will play in the residential housing finance system in the future. The timing and impact on our business of any resulting changes is uncertain. Many of the proposed changes would require Congressional action to implement and it is difficult to estimate when Congressional action would be final and how long any associated phase-in period may last.

 For additional information about the business practices of the GSEs, see our risk factor titled "Changes in the business practices of Fannie Mae and Freddie Mac ("the GSEs"), federal legislation that changes their charters or a restructuring of the GSEs could reduce our revenues or increase our losses." in Item 1A.

 State Regulations
 The insurance laws of 16 jurisdictions, including Wisconsin, our domiciliary state, require a mortgage insurer to maintain a minimum amount of statutory capital relative to its RIF (or a similar measure) in order for the mortgage insurer to continue to write new business. We refer to these requirements as the "State Capital Requirements." While they vary among jurisdictions, the most common State Capital Requirements allow for a maximum risk-to-capital ratio of 25 to 1. A risk-to-capital ratio will increase if (i) the percentage decrease in capital exceeds the percentage decrease in insured risk, or (ii) the percentage increase in capital is less than the percentage increase in insured risk. Wisconsin does not regulate capital by using a risk-to-capital measure but instead requires a MPP. MGIC's "policyholder position" includes its net worth or surplus and its contingency reserve.

 At December 31, 2024, MGIC's risk-to-capital ratio was 10.0 to 1, below the maximum allowed by the jurisdictions with State Capital Requirements, and its policyholder position was $3.6 billion above the required MPP of $2.2 billion. The calculation of our risk-to-capital ratio and MPP reflect full credit for the risk ceded under our reinsurance transactions. It is possible that under the revised State Capital Requirements discussed below, MGIC will not be allowed full credit for the risk ceded under such transactions. If MGIC is not allowed an agreed level of credit under either the State Capital Requirements or the PMIERs, MGIC may terminate the reinsurance transactions, without penalty.

 At this time, we expect MGIC to continue to comply with the current State Capital Requirements; however, refer to our risk factor titled "State capital requirements may prevent us from continuing to write new insurance on an uninterrupted basis" in Item 1A for more information about matters that could negatively impact our compliance with State Capital Requirements.

 In 2023, the NAIC adopted a revised Mortgage Guaranty Insurance Model Act. The updated Model Act includes requirements relating to, among other things: (i) capital and minimum capital requirements, and contingency reserves; (ii) restrictions on mortgage insurers' investments in notes secured by mortgages; (iii) prudent underwriting standards and formal underwriting guidelines; (iv) the establishment of formal, internal "Mortgage Guaranty Quality Control Programs" with respect to in-force business; and (v) reinsurance

 MGIC Investment Corporation 2024 Form 10-K | 51

 and prohibitions on captive reinsurance arrangements. It is uncertain when the revised Model Act will be adopted in any jurisdiction. The provisions of the Model Act, if adopted in their final form, are not expected to have a material adverse effect on our business. It is unknown whether any changes will be made by state legislatures prior to adoption, and the effect changes, if any, will have on the mortgage guaranty insurance market generally, or on our business. Wisconsin, where MGIC is domiciled, has begun the process to replace current Mortgage Insurance regulations with the Model Act, though it is expected that some changes will be made before formal adoption.

 FACTORS AFFECTING OUR RESULTS
 Our current and future business, results of operations and financial condition are impacted by macroeconomic conditions, such as interest rates, home prices, housing demand, level of employment, inflation, pandemics, restrictions on and costs of mortgage credit, and other factors. For additional information on how our business may be impacted see our risk factor titled "Downturns in the domestic economy or declines in home prices may result in more homeowners defaulting and our losses increasing, with a corresponding decrease in our returns."

 The future effects of climate change on our business are uncertain. For information about possible effects, please refer to our risk factor titled "Pandemics, hurricanes and other disasters may adversely impact our results of operations and financial condition."

 Our results of operations are affected by:

 Premiums written and earned
 Premiums written and earned in a year are influenced by:
 • NIW, which increases IIF. Many factors affect NIW, including the volume of low down payment home mortgage originations and competition to provide credit enhancement on those mortgages from the FHA, the VA, and other mortgage insurers. Other alternatives to mortgage insurance also impact NIW, including GSE programs that may reduce or eliminate the demand for mortgage insurance. NIW does not include loans previously insured by us that are modified, such as loans modified under HARP.

 • Cancellations, which reduce IIF. Cancellations from refinancings may occur when borrowers achieve the required amount of home equity through loan amortization, loan payoffs, or home price appreciation. Refinance-related cancellations are influenced by the level of current mortgage interest rates compared to the mortgage coupon rates throughout the in force book, current home values relative to values when the loans in the in force book were insured and the terms on which mortgage credit is available. Policy rescissions also cause cancellations requiring us to return any premiums received, from the date of default, on the rescinded policies and claim payments. Cancellations of single premium policies, which are generally non-refundable, result in immediate recognition of any remaining unearned premium.

 • Premium rates, which vary by product type, the risk characteristics of the insured loans, competitive pressures, the percentage of coverage on the insured loans, and PMIERs capital requirements. The substantial majority of our monthly and annual mortgage insurance premiums are under premium plans for which, for the first ten years of the policy, the amount of premium is determined by multiplying the initial premium rate by the original loan balance; thereafter, the premium rate resets to a lower rate used for the remaining life of the policy. The remainder of our monthly and annual premiums are under premium plans for which premiums are determined by a fixed percentage of the loan's amortizing balance over the life of the policy.

 • Premiums ceded, net of profit commission, under our QSR Transactions, and premiums ceded under our XOL Transactions, are primarily affected by the percentage of our IIF subject to our reinsurance transactions. The profit commission under our QSR Transactions also varies inversely with the level of ceded losses incurred on a "dollar for dollar" basis and can be eliminated at ceded loss levels higher than what we have experienced on our QSR Transactions. As a result, lower levels of losses incurred result in a higher profit commission and less benefit from ceded losses incurred; higher levels of losses incurred result in more benefit from ceded losses incurred and a lower profit commission (or for certain levels of accident year loss ratios, its elimination). See Note 9 – "Reinsurance" to our consolidated financial statements for a discussion of our reinsurance transactions.

 • Premiums earned are generated by the insurance that is in force during all or a portion of the period. A change in the average IIF in the current period compared to an earlier period is a factor that will increase (when the average in force is higher) or reduce (when it is lower) premiums written and earned in the current period, although this effect may be enhanced (or mitigated) by the factors discussed above.

 Investment income
 Our investment portfolio is composed principally of investment grade fixed income securities. The principal factors that influence investment income are the size of the portfolio and its yield. As measured by amortized cost (which excludes changes in fair value, such as from changes in interest rates), the size of the investment portfolio is mainly a function of cash generated from (or used in) operations, such as net premiums written, investment income, net claim payments and expenses, and cash provided by (or used for) non-operating activities, such as debt or stock issuances or repurchases, and dividends.

 MGIC Investment Corporation 2024 Form 10-K | 52

 Losses incurred
 Losses incurred are the current expense that reflects claim payments, costs of settling claims, and changes in our estimates of payments that will ultimately be made as a result of delinquencies on insured loans. As explained under " Critical Accounting Estimates " below, except in the case of a premium deficiency reserve, we recognize an estimate of this expense only for delinquent loans. The level of new delinquencies has historically followed a seasonal pattern, with new delinquencies in the first half of the year lower than new delinquencies in the latter half of the year. The state of the economy, local housing markets, pandemics, natural disasters, and various other factors may result in delinquencies not following the typical pattern. Losses incurred are generally affected by:

 • The state of the economy, including unemployment and housing values, each of which affects the likelihood that loans will become delinquent and whether loans that are delinquent cure their delinquency.

 • The product mix of the in force book, with loans having higher risk characteristics generally resulting in higher delinquencies and claims.

 • The size of loans insured, with higher average loan amounts on delinquent loans tending to increase incurred losses.

 • The percentage of coverage on insured loans, with deeper average coverage on delinquent loans tending to increase incurred losses.

 • The distribution of claims over the life of a book. Historically, the first few years after loans are originated are a period of relatively low claims, with claims increasing substantially for several years subsequent and then declining. Annual persistency, the condition of the economy, including unemployment and housing prices, and other factors can affect this pattern. For example, a weak economy or housing value declines can lead to claims from older books increasing, continuing at stable levels or experiencing a lower rate of decline. See further information under "Mortgage insurance earnings and cash flow cycle" below.

 • Losses ceded under reinsurance transactions. See Note 9 – "Reinsurance" to our consolidated financial statements for a discussion of our reinsurance transactions.

 • The rate at which we rescind policies or curtail claims. Our estimated loss reserves incorporate our estimates of future rescissions of policies and curtailments of claims, and reversals of rescissions and curtailments. We collectively refer to such rescissions and denials as "rescissions" and variations of this term. We call reductions to claims "curtailments."

 Underwriting and other expenses
 Underwriting and other expenses includes items such as employee compensation, fees for professional and consulting services, depreciation and maintenance expense, and premium taxes, and are reported net of ceding commissions associated with our QSR Transactions. Employee compensation expenses are variable due to share-based compensation, changes in benefits, and changes in headcount (which can fluctuate due to volume of NIW). See Note 9 – "Reinsurance" and Note 18 – "Segment Reporting" to our consolidated financial statements for a discussion of ceding commission on our QSR Transactions and discussion on significant segment expenses.

 Interest expense reflects the interest associated with our outstanding debt obligations discussed in Note 7 – "Debt" to our consolidated financial statements and under " Liquidity and Capital Resources " below.

 Other
 Certain activities that we do not consider being part of our fundamental operating activities may also impact our results of operations and are described below.

 • Gains (losses) on investments and other financial instruments
 • Fixed income securities. Investment gains and losses reflect the difference between the amount received on the sale of a fixed income security and the fixed income security's cost basis, as well as any credit allowances and any impairments on securities we intend to sell prior to recovery of its amortized cost basis. The amount received on the sale of fixed income securities is affected by the coupon rate of the security compared to the yield of comparable securities at the time of sale.
 • Equity securities. Investment gains and losses reflect the periodic change in fair value.
 • Financial instruments. Investment gains and losses on the embedded derivative on our Home Re Transactions reflect the present value impact of the variation in investment income on assets on the insurance-linked notes held by the reinsurance trusts and the contractual reference rate used to calculate the reinsurance premiums we estimate we will pay over the estimated remaining life.

 • Gains and losses on debt extinguishment
 Gains and losses on debt extinguishment result from discretionary activities that are undertaken to enhance our capital position and / or improve our debt profile. Extinguishing our outstanding debt obligations early through these discretionary

 MGIC Investment Corporation 2024 Form 10-K | 53

 activities may result in gains or losses primarily driven by differences in the payment of consideration from the carrying value, and the write off of unamortized debt issuance costs on the extinguished portion of the debt.

 Refer to " Explanation and reconciliation of our use of Non-GAAP financial measures " below to understand how these items impact our evaluation of our core financial performance.

 MORTGAGE INSURANCE EARNINGS AND CASH FLOW CYCLE
 In general, the majority of any underwriting profit that a book generates occurs in the early years of the book, with the largest portion of any underwriting profit realized in the first year following the year the book was written. Subsequent years of a book may result in either underwriting profit or underwriting losses. This pattern of results typically occurs because relatively few of the incurred losses on delinquencies that a book will ultimately experience typically occur in the first few years of the book, when premium revenue is highest, while subsequent years are affected by declining premium revenues, as the number of insured loans decreases (primarily due to loan prepayments) and increasing losses. The state of the economy, local housing markets, pandemics, natural disasters, and various other factors may result in delinquencies not following the typical pattern.

 CYBERSECURITY
 As part of our business, we maintain large amounts of confidential and proprietary information both on our own servers and those of cloud computing services. This includes personal information of consumers and our employees. Personal information is subject to an increasing number of federal and state laws and regulations regarding privacy and data security, as well as contractual commitments. Any failure or perceived failure by us, or by the vendors with whom we share this information, to comply with such obligations may result in damage to our reputation, financial losses, litigation, increased costs, regulatory penalties or customer dissatisfaction.

 All information technology systems are potentially vulnerable to damage or interruption from a variety of sources, including by cyber attacks, such as those involving ransomware. The Company discovers vulnerabilities and regularly blocks attempts at unauthorized access to its systems, through threats such as malware and computer virus attacks, unauthorized access, system failures and disruptions. Threats have the potential to jeopardize the information processed and stored in, and transmitted through, our computer systems and networks and otherwise cause interruptions or malfunctions in our operations, which could result in damage to our reputation, financial losses, litigation, increased costs, regulatory penalties or customer dissatisfaction. We could be similarly affected by threats against our vendors and/or third-parties with whom we share information.

 Globally, attacks are expected to continue accelerating in both frequency and sophistication with increasing use by actors of tools, techniques, and technological advances that may hinder the Company's ability to identify, investigate and recover from incidents. Such attacks may also increase as a result of retaliation by threat actors against actions taken by the U.S. and other countries in connection with wars and other global events. The Company operates under a hybrid workforce model and such model may be more vulnerable to security breaches.

 While we have information security policies and systems in place to secure our information technology systems and to prevent unauthorized access to or disclosure of sensitive information, there can be no assurance with respect to our systems and those of our third-party vendors that unauthorized access to the systems or disclosure of the sensitive information, either through the actions of third parties or employees, will not occur. Due to our reliance on information technology systems, including ours and those of our customers and third-party service providers, and to the sensitivity of the information that we maintain, unauthorized access to the systems or disclosure of the information could adversely affect our reputation, severely disrupt our operations, result in a loss of business and expose us to material claims for damages and may require that we provide free credit monitoring services to individuals affected by a security breach.

 Should we experience an unauthorized disclosure of information or a cyber attack, including those involving ransomware, some of the costs we incur may not be recoverable through insurance, or legal or other processes, and this may have a material adverse effect on our results of operations.
 For additional information about our IT systems and cybersecurity, see our risk factor titled "Information technology system failures or interruptions may materially impact our operations and adversely affect our financial results" and "We could be materially adversely affected by a cyber security breach or failure of information security controls." in Item 1A and Item 1C. Cybersecurity.

 MGIC Investment Corporation 2024 Form 10-K | 54

 EXPLANATION AND RECONCILIATION OF OUR USE OF NON-GAAP FINANCIAL MEASURES

 NON-GAAP FINANCIAL MEASURES
 We believe that use of the Non-GAAP financial measures of adjusted pre-tax operating income (loss), adjusted net operating income (loss) and adjusted net operating income (loss) per diluted share facilitate the evaluation of the company's core financial performance thereby providing relevant information to investors. These measures are not recognized in accordance with GAAP and should not be viewed as alternatives to GAAP measures of performance.

 Adjusted pre-tax operating income (loss) is defined as GAAP income (loss) before tax, excluding the effects of net realized investment gains (losses), gain and losses on debt extinguishment, and infrequent or unusual non-operating items where applicable.

 Adjusted net operating income (loss) is defined as GAAP net income (loss) excluding the after-tax effects of net realized investment gains (losses), gain and losses on debt extinguishment, and infrequent or unusual non-operating items where applicable. The amounts of adjustments to components of pre-tax operating income (loss) are tax effected using a federal statutory tax rate of 21%.

 Adjusted net operating income (loss) per diluted share is calculated in a manner consistent with the accounting standard regarding earnings per share by dividing (i) adjusted net operating income (loss) after making adjustments for interest expense on convertible debt, whenever the impact is dilutive by (ii) diluted weighted average common shares outstanding, which reflects share dilution from unvested restricted stock units and from convertible debt when dilutive under the "if-converted" method.

 Although adjusted pre-tax operating income (loss) and adjusted net operating income (loss) exclude certain items that have occurred in the past and are expected to occur in the future, the excluded items represent items that are: (1) not viewed as part of the operating performance of our primary activities; or (2) impacted by both discretionary and other economic or regulatory factors and are not necessarily indicative of operating trends, or both. These adjustments, along with the reasons for their treatment, are described below. Trends in the profitability of our fundamental operating activities can be more clearly identified without the fluctuations of these adjustments. Other companies may calculate these measures differently. Therefore, their measures may not be comparable to those used by us.

 (1)Net realized investment gains (losses). The recognition of net realized investment gains or losses can vary significantly across periods as the timing of individual securities sales is highly discretionary and is influenced by such factors as market opportunities, our tax and capital profile, and overall market cycles.
 (2)Gains and losses on debt extinguishment. Gains and losses on debt extinguishment result from discretionary activities that are undertaken to enhance our capital position, improve our debt profile, and/or reduce potential dilution from our outstanding convertible debt.
 (3)Infrequent or unusual non-operating items. Items that are non-recurring in nature and are not part of our primary operating activities.

 MORTGAGE INSURANCE PORTFOLIO
 MORTGAGE ORIGINATIONS
 Our NIW is affected by the total mortgage originations, the percentage of total mortgage originations using PMI, and our market share within the PMI industry.

 The total amount of mortgage originations is generally influenced by the level of new and existing home sales, interest rates, the percentage of homes purchased for cash, and the level of refinance activity. PMI market share of total mortgage originations is influenced by the mix of purchase and refinance originations. PMI market share is also impacted by the market share of total originations of the FHA, VA, USDA, and other alternatives to mortgage insurance, including GSE programs that may reduce or eliminate the demand for mortgage insurance.

 The increase in total mortgage originations in 2024, as compared to 2023, reflects an increase in refinance volumes, attributed to a brief decline in interest rates during 2024, while purchase origination activity remained relatively flat. Total mortgage originations are forecasted to be higher in 2025, compared to 2024.

 IIF AND RIF
 Our IIF increased in 2024 compared to 2023. The amount of our IIF and RIF is impacted by the amount of NIW, cancellations, and principal payments received on our primary IIF during the period. Cancellation activity is impacted by refinancing activity, policies cancelled when borrowers achieve the required amount of home equity, and cancellations due to claim payment. Refinancing activity has historically been affected by the level of mortgage interest rates and the level of home price appreciation. Cancellations generally move inversely to the change in the direction of interest rates, although they generally lag a change in direction.

 Annual Persistency. Our annual persistency at December 31, 2024 was 84.8% compared to 86.1% at December 31, 2023. Since 2018, our annual persistency ranged from a high of 86.3% at September 30, 2023 to a low of 60.7% at March 31, 2021. Our persistency rate is primarily affected by the level of current mortgage interest rates compared to the mortgage coupon rates on our IIF, which affects the vulnerability of the IIF to refinancing; and the current amount of equity that borrowers have in the homes underlying our IIF.

 CREDIT PROFILE OF OUR PRIMARY RIF
 Our 2009 and later books possess significantly improved risk characteristics when compared to our 2005-2008 books. Modification and refinance programs, such as HAMP and HARP, which expired at the end of 2016 and 2018, respectively, but have been replaced by other GSE modification programs, make outstanding loans more affordable to borrowers with the goal of reducing the number of foreclosures. As of December 31, 2024, loans with modifications accounted for approximately 3.0% of our total primary RIF, compared to 3.6% at December 31, 2023. Loans associated with 87.6% of all our modifications were current as of December 31, 2024. For additional information on the composition of our primary RIF see "Business - Our Products and Services"

 CRT AND POOL INSURANCE
 In connection with the GSEs CRT programs, MAC an insurance subsidiary of MGIC provides insurance and reinsurance covering portions of the credit risk related to certain reference pools of mortgages acquired by the GSEs. Our RIF, as reported to us, related to these programs was approximately $392 million and $310 million as of December 31, 2024 and December 31, 2023, respectively.

 MGIC has written no new pool insurance since 2008, however, MGIC may write pool risk in the future. Our direct pool RIF was $226 million ($177 million on pool policies with aggregate loss limits and $49 million on pool policies without aggregate loss limits) at December 31, 2024 compared to $256 million ($186 million on pool policies with aggregate loss limits and $70 million on pool policies without aggregate loss limits) at December 31, 2023.

 NET PREMIUMS WRITTEN AND EARNED
 Net premiums written and earned increased 2% in 2024 compared with the prior year. The increase in premiums written and earned in 2024 compared to the prior year is primarily due to a decrease in ceded premiums.

 Premium yields
 Premium yield is net premiums earned divided by average IIF during the year and is influenced by a number of key drivers, which have a varying impact from period to period. The following table provides information related to our premium yield for 2024, and 2023.

 Changes in the net premium yields when compared to the respective prior year periods reflect the following:

 In force Portfolio Yield

 The yield on our current IIF is impacted by the premium rates on our IIF. Premium rates are generally affected by risk characteristics on our NIW, the amount of capital we are required to hold, and competition in the industry.

 Premium Refunds

 Premium refunds are primarily driven by our estimate of refundable premiums on our delinquency inventory and claim activity. Our estimate of refundable premium on our delinquency inventory fluctuates with changes in our delinquency inventory and our estimate of the number of loans in our delinquency inventory that will result in a claim. Lower levels of claims received results in a lower level of premium refunds.

 Accelerated earnings on single premium policies

 A low level of refinance transactions reduces the benefit from accelerated earned premium from cancellation of single premium policies prior to their estimated policy life.

 MGIC Investment Corporation 2024 Form 10-K | 61

 Ceded premiums earned, net of profit commission and assumed premiums

 Ceded premiums earned, net of profit commission adversely impact our net premium yield. Ceded premiums earned, net of profit commission, are associated with the QSR Transactions and the XOL Transactions. Assumed premiums consists primarily of premiums from GSE CRT programs. See "Reinsurance Transactions" below for further discussion on our reinsurance transactions.

 As discussed in our risk factor titled "Competition or changes in our relationships with our customers could reduce our revenues, reduce our premium yields and/or increase our losses," the private mortgage insurance industry is highly competitive and premium rates have declined over the past several years. We expect our in force portfolio premium yield will remain relatively flat in 2025 driven by sustained high credit quality and an elevated annual persistency.

 See " Overview – Factors Affecting Our Results " above for additional factors that also influence the amount of net premiums written and earned in a year.

 REINSURANCE TRANSACTIONS
 Quota Share Reinsurance
 Our quota share reinsurance affects various lines of our statements of operations and therefore we believe it should be analyzed by reviewing its total effect on our pre-tax income, described as follows.

 We cede a fixed percentage of premiums earned and received on insurance covered by the transactions.

 We receive the benefit of a profit commission through a reduction in the premiums we cede. The profit commission varies inversely with the level of losses incurred on a "dollar for dollar" basis and can be eliminated at loss levels higher than what we have experienced. As a result, lower levels of ceded losses incurred result in less benefit from ceded losses incurred, and a higher profit commission; higher levels of ceded losses incurred result in more benefit from ceded losses incurred and a lower profit commission (or for certain levels of accident year loss ratios, its elimination).

 We receive the benefit of a ceding commission through a reduction in underwriting expenses equal to 20% of premiums ceded (before the effect of the profit commission).

 We cede a fixed percentage of losses incurred on insurance covered by the transactions.

 Ceded premiums written and earned, net of profit commission decreased in 2024 when compared with the prior year primarily due to a decrease in the average amount of our IIF subject to our QSR Transactions throughout the year in comparison to the prior year. Ceded losses incurred are impacted by the delinquencies covered by our QSR Transactions, our estimates of payments that will be ultimately made on those delinquencies, and claim payments covered by our QSR Transactions.

 In the fourth quarter of 2024 we exercised the early termination option on our 2021 quota share reinsurance transaction. After providing reinsurers the termination notice but prior to the termination date, we agreed to amended terms with certain participants from the existing reinsurance panel that effectively reduced the quota share cede rate from 30% to 26% on the remaining eligible insurance. We

 MGIC Investment Corporation 2024 Form 10-K | 62

 paid a termination fee of approximately $1 million to the non-participating reinsurers. The amended agreement is effective December 31, 2024. We terminated our 2020 QSR Transaction effective December 31, 2023 and incurred an early termination fee of $5 million.

 We executed a 40% QSR transaction with a group of unaffiliated reinsurers covering most of our new insurance written in 2025 and 2026.

 Covered Risk
 The percentages of our NIW, new risk written, IIF, and RIF subject to our QSR Transactions as shown in the following table will vary from period to period in part due to the mix of our risk written during the period and the number of active QSR Transactions.

 Excess of Loss Reinsurance
 We have excess of loss reinsurance ("XOL Transactions") with panels of unaffiliated reinsurers executed through the traditional reinsurance market ("Traditional XOL Transaction") and with unaffiliated special purpose insurers ("Home Re Transactions").

 For policies covered by our Traditional XOL Transactions, we retain the first layer of the aggregate losses paid, and the reinsurers will then provide second layer coverage up to the outstanding reinsurance coverage amount. We retain losses paid in excess of the outstanding reinsurance coverage amount. The reinsurance coverage is subject to adjustment based on the risk characteristics of the covered loans until the initial excess of loss reinsurance coverage layer has been finalized.

 The Home Re Transactions are executed through the issuance of insurance linked notes ("ILNs"). At December 31, 2024 our Home Re Transactions provided $829.4 million of loss coverage on a portfolio of policies having an in force date from August 1, 2020 through December 31, 2021, and from June 1, 2022 through August 31, 2023; all dates inclusive. For this reinsurance coverage, we retain the first layer of the respective aggregate losses paid, and a Home Re Entity will then provide second layer coverage up to the outstanding reinsurance amount.

 In 2024, we exercised our option to terminate the reinsurance agreement with Home Re 2020-1, Ltd. and Home Re 2018-1, Ltd. In connection with the terminations, the insurance linked notes issued by Home Re 2020-1 Ltd. and Home Re 2018-1, Ltd. were redeemed in full. We also terminated our reinsurance agreement with Home Re 2019-1, Ltd.

 We ceded premiums on our XOL Transactions of $66.6 million and $78.9 million for the years ended December 31, 2024 and 2023, respectively.

 LOSSES INCURRED, NET
 As discussed in "Critical Accounting Estimates" below and consistent with industry practices, we establish case loss reserves for future claims on delinquent loans that were reported to us as two payments past due and have not become current or resulted in a claim payment. Such loans are referred to as being in our delinquency inventory. Case loss reserves are established based on estimating the number of loans in our delinquency inventory that will result in a claim payment, which is referred to as the claim rate, and further estimating the amount of the claim payment, which is referred to as claim severity.

 IBNR reserves are established for estimated losses from delinquencies we estimate have occurred prior to the close of an accounting period, but have not yet been reported to us. IBNR reserves are also established using estimated claim rates and claim severities.

 Estimation of losses is inherently judgmental. Even in a stable environment, changes to our estimates could result in a material impact to our consolidated results of operations and financial position. The conditions that affect the claim rate and claim severity include the current and future state of the domestic economy, including unemployment, and the current and future strength of local housing markets; exposure on insured loans; the amount of time between delinquency and claim filing (all else being equal, the longer the period between delinquency and claim filing, the greater the severity); and curtailments and rescissions. The actual amount of the claim payments may be substantially different than our loss reserve estimates. Our estimates could be adversely affected by several factors, including a deterioration of regional or national economic conditions, including unemployment, leading to a reduction in borrowers' income and thus their ability to make mortgage payments, the impact of past and future government initiatives and actions taken by the GSEs (including mortgage forbearance programs and foreclosure moratoriums), and a drop in housing values which may affect borrower willingness to continue to make mortgage payments when the value of the home is below the mortgage balance. Loss reserves in future periods will also be dependent on the number of loans reported to us as delinquent.

 Generally, losses follow a seasonal trend in which the second half of the year has weaker credit performance than the first half, with higher new notice activity and a lower cure rate. The state of the economy, local housing markets, pandemics, natural disasters, and various other factors, may result in delinquencies not following the typical pattern.

 For information on how pandemics and natural disasters could affect losses incurred, net see our risk factors titled "Pandemics, hurricanes and other disasters may adversely impact our results of operations and financial condition". As discussed in our risk factor titled "Because we establish loss reserves only upon a loan delinquency rather than based on estimates of our ultimate losses on risk in force, losses may have a disproportionate adverse effect on our earnings in certain periods" if we have not received a notice of delinquency with respect to a loan and if we have not estimated the loan to be delinquent as of December 31, 2024, through our IBNR reserve, then we have not yet recorded an incurred loss with respect to that loan.

 Losses incurred, net increased to $(14.9) million compared to $(20.9) million in 2023. While new delinquency notices added $197.6 million to losses incurred in 2024, our re-estimation of loss reserves on previously received delinquency notices resulted in favorable development of approximately $212.5 million. In 2023, new delinquency notices added $187.7 million to losses incurred, our re-estimation of loss reserves on previously received delinquency notices resulted in favorable development on previously received delinquency notices of $208.5 million. The favorable development for both periods primarily resulted from a decrease in the expected claim rate on previously received delinquencies. Home price appreciation in recent years has allowed some borrowers to cure their delinquencies through the sale of their property.

 See "New notice activity" and "Claims severity" below for additional factors and trends that impact these loss reserve assumptions.

 Claims severity
 Factors that impact claim severity include:

 economic conditions at that time, including home prices compared to home prices at the time of placement of coverage

 exposure on the loan, which is the unpaid principal balance of the loan times our insurance coverage percentage,

 length of time between delinquency and claim filing (which impacts the amount of interest and expenses, with a longer period between default and claim filing generally increasing severity), and

 curtailments.

 As discussed in Note 8 - "Loss Reserves," our loss reserves estimates take into consideration trends over time, because the development of the delinquencies may vary from period to period without establishing a meaningful trend. An increase in third party property sales, prior to claim settlement has resulted in a decrease in the average claim paid and the average claim paid as a percentage of exposure in recent years. We expect average claims paid as a percentage of exposure to increase as we receive delinquencies that have not experienced the same level of home price appreciation as in recent years. The extent and timing of these increases are uncertain.

 The majority of loans insured prior to 2014 (which represent 29% of the loans in the delinquency inventory) are covered by master policy terms that, except under certain circumstances, do not limit the number of years that an insured can include interest when filing a claim. Under our current master policy terms, an insured can include accumulated interest when filing a claim only for the first three years the loan is delinquent. In each case, the insured must comply with its obligations under the terms of the applicable master policy.

 (1)Approximately 27% and 37% of the delinquent inventory that has been delinquent for 12 consecutive months or more has been delinquent for at least 36 consecutive months as of December 31, 2024 and 2023, respectively.

 The length of time a loan is in the delinquency inventory can differ from the number of payments that the borrower has not made or is considered delinquent. These differences typically result from a borrower making monthly payments that do not result in the loan becoming fully current. Generally, a defaulted loan with more missed payments is more likely to result in a claim. The number of payments that a borrower is delinquent is shown in the following table.

 NET LOSSES AND LAE PAID
 Net losses and LAE paid in 2024 were consistent with 2023. The primary average claim paid can vary materially from period to period based upon a variety of factors, including the local market conditions, average loan amount, average coverage percentage, the amount of time between delinquency and claim filing, and our loss mitigation efforts on loans for which claims are paid. Net losses and LAE paid have been positively impacted by home price appreciation in recent years that has allowed more delinquent loans to cure through the sale of the property. In addition, an increase in third party property sales prior to claim settlement has resulted in a decrease in the average claim paid on the claims we do receive. We expect net losses and LAE paid to increase, however, the magnitude and timing of the increases are uncertain.

 On our primary business, the highest claim frequency years have typically been the third and fourth year after loan origination. However, the pattern of claim frequency can be affected by many factors, including persistency and deteriorating economic conditions. Deteriorating economic conditions can result in increasing claims following a period of declining claims. As of December 31, 2024, 50% of our primary RIF was written subsequent to December 31, 2021, 74% of our primary RIF was written subsequent to December 31, 2020, and 87% of our primary RIF was written subsequent to December 31, 2019.

 UNDERWRITING AND OTHER EXPENSES, NET
 Underwriting and other expenses includes items such as employee compensation costs, outside service expenses, premium taxes, and depreciation and maintenance expense, and are reported net of ceding commissions. See Note 18. - "Segment Reporting" to our consolidated financial statements for a discussion around significant segment expenses.

 Underwriting and other expenses, net for 2024 decreased to $209.3 million from $226.0 million in 2023. The decrease was primarily due to a decrease in pension expenses, and a decrease in outside service expenses. Pension expenses were higher in 2023 due to settlement accounting charges.

 The underwriting expense ratio is the ratio, expressed as a percentage, of the underwriting and operating expenses, net and amortization of DAC of our combined insurance operations (which excludes underwriting and operating expenses of our non-insurance subsidiaries) to net premiums written. The underwriting expense ratio decreased in 2024 compared with 2023 due to a decrease in underwriting and operating expenses, net, and an increase in net premiums written.

 INVESTMENT PORTFOLIO
 The investment portfolio increased to $5.9 billion as of December 31, 2024 (2023: $5.7 billion), primarily due to a decrease in the prevailing market interest rates.

 The return we generate on our investment portfolio is an important component of our consolidated financial results. Our investment portfolio primarily consists of a diverse mix of highly rated fixed income securities. The investment portfolio is designed to achieve the following objectives:

 Operating Companies (1)

 Holding Company

 Preserve PMIERs assets

 Provide liquidity with minimized realized loss

 Maximize total return with emphasis on book yield, subject to our other objectives

 Maintain highly liquid, low volatility assets

 Limit portfolio volatility

 Maintain high credit quality

 Duration 3.5 to 5.5 years

 Duration maximum of 2.5 years

 (1)Primarily MGIC

 To achieve our portfolio objectives, our asset allocation considers the risk and return parameters of the various asset classes in which we invest. This asset allocation is informed by, and based on, the following factors:

 economic and market outlooks;

 diversification effects;

 security duration;

 liquidity;

 capital considerations; and

 income tax rates.

 The average duration and embedded investment yield of our investment portfolio as of December 31, 2024 and 2023 is shown in the following table.

 Investments outlook
 The Federal Open Market Committee ("FOMC") reduced the federal funds rate three times throughout 2024 from 5.50% to 4.50% as it balanced maintaining a sufficiently restrictive monetary policy to return inflation to its long-run target, while also achieving its employment goals. In January, 2025, the FOMC held the federal funds rate at 4.25% to 4.50%. The FOMC acknowledged inflation data has demonstrated moderation to the 2% inflation target, and expressed support for further rate cuts in 2025 provided disinflationary progress continues across a broad range of core goods and services prices. The forward curve, which currently includes rate cuts this year indicates a less restrictive FOMC policy through the end of 2025. The lagged effects of the FOMC's actions and other ongoing macroeconomic and geopolitical factors could create significant economic uncertainty and alter forward rate expectations, which may result in interest rate and credit spread volatility. Market volatility resulting from these factors, particularly the absolute level of rates and the rate of change, will continue to impact our investment valuations and returns.

 The changes in unrealized investment gains and losses generally do not alter the management of our investment portfolio. We seek to manage our exposure to interest rate risk and volatility by maintaining a diverse mix of securities with an intermediate duration profile and generally hold fixed income investments until maturity. The quality of our fixed income portfolio remains very high and changes in unrealized gains and losses have little impact on our cash flows, statutory surplus, or other capital requirements.

 While a higher interest rate environment may continue to adversely impact the fair values of existing fixed income investments, it presents an opportunity for continued investment into securities with yields in excess of the book yield on our portfolio. Increases in market-based portfolio yields are expected to result in higher net investment income in future periods if the basis of invested assets is stable or increases in size. In addition to fixed income securities, we also hold cash and cash equivalents which yield returns that generally reflect the federal funds rate.

 CASH AND CASH EQUIVALENTS
 Cash and cash equivalents decreased to $229.5 million, as of December 31, 2024 (2023: $363.7 million), as net cash generated from operating activities was substantially used in financing activities.

 DEFERRED INCOME TAXES
 Our net deferred tax asset was $69.9 million as of December 31, 2024 (2023: $79.8 million). The change to our deferred tax asset during 2024 was primarily due to the change in other comprehensive income attributable to our benefit plans. We owned $968.2 million and $848.6 million of tax and loss bonds at December 31, 2024 and December 31, 2023, respectively. See Note 12 – "Income Taxes" to our consolidated financial statements for additional disclosure on the components of our deferred tax assets and liabilities.

 LOSS RESERVES AND REINSURANCE RECOVERABLE ON LOSS RESERVES
 Our loss reserves include estimates of losses and settlement expenses on (1) loans in our delinquency inventory (known as case reserves), (2) IBNR delinquencies, and (3) LAE. Our gross reserves are reduced by reinsurance recoverable on loss reserves to calculate a net reserve balance. Loss reserves decreased to $462.7 million as of December 31, 2024, from $505.4 million of December 31, 2023. Reinsurance recoverables on loss reserves were $47.3 million and $33.3 million as of December 31, 2024 and December 31, 2023, respectively. The decrease in loss reserves is primarily due to favorable development of $212.5 million on previously received delinquency notices, partially offset by loss reserves established on new delinquency notices. The reinsurance recoverable on loss reserves is impacted by the change in direct reserves and the percentage of our delinquency inventory covered by reinsurance transactions.

 UNEARNED PREMIUM
 Our unearned premium decreased to $120.4 million as of December 31, 2024 from $157.8 million as of December 31, 2023 primarily due to the run-off of unearned premium on our existing portfolio of single premium policies, partially offset by new premium written on single premium policies.

 SHAREHOLDER'S EQUITY
 The increase in shareholders' equity is primarily due to net income and a decrease in the accumulated other comprehensive losses reported in shareholders' equity related to the fair value of our investment portfolio and net changes in our benefit plan assets and obligations, partially offset by repurchases of our common stock and dividends paid to shareholders in 2024.

 Prior to November 15, 2024, shares we repurchased were held in treasury stock unless they were reissued under the discretion of our Board of Directors. As of November 15, 2024, we retired all shares of our treasury stock. There was no change to our shareholders' equity as a result of the retirement. Subsequent to the retirement of the treasury stock, all shares of our common stock that we repurchase are immediately retired. See Note 13 - "Shareholders' Equity" to our consolidated financial statements for additional information on our retirement of treasury stock.

 LIQUIDITY AND CAPITAL RESOURCES

 CONSOLIDATED CASH FLOW ANALYSIS
 We have three primary types of cash flows: (1) operating cash flows, which consist mainly of cash generated by our insurance operations and income earned on our investment portfolio, less amounts paid for claims, interest expense and operating expenses, (2) investing cash flows related to the purchase, sale and maturity of investments and purchases of property and equipment and (3) financing cash flows generally from activities that impact our capital structure, such as changes in debt and shares outstanding, and dividend payments. The following table summarizes these three cash flows on a consolidated basis for the last two years.

 Operating activities
 The following list highlights the major sources and uses of cash flow from operating activities:

 Sources

 +
 Premiums received

 +
 Loss payments from reinsurers

 +
 Investment income

 Uses

 -
 Claim payments

 -
 Premium ceded to reinsurers

 -

 -
 Operating expenses

 -
 Tax payments

 Our largest source of cash is from premiums received from our insurance policies, which we receive on a monthly installment basis for most policies. Premiums are received at the beginning of the coverage period for single premium and annual premium policies. Our largest cash outflow is generally for claims that arise when a delinquency results in an insured loss. Based on historical experience, we expect our future claim payments associated with established case loss reserves to pay out at or within 5 years, with the majority of future claim payments made within one to three years. Net losses and LAE paid in recent years has been positively impacted by home price appreciation that has allowed more delinquent loans to cure through the sale of the property. In addition, an increase in third party property sales prior to claim settlement, has resulted in a decrease in the average claim paid on the claims we do receive. We expect net losses and LAE paid to increase, however, the magnitude and timing of the increases are uncertain.

 We invest our net cash flow in various investment securities that earn interest. We also use cash to pay for our ongoing expenses such as salaries, debt interest, professional services and occupancy costs.

 In connection with our reinsurance transactions, we cede, or pay out, part of the premiums we receive to our reinsurers and collect cash when claims subject to our reinsurance coverage are paid.

 Net cash provided by operating activities in 2024 increased compared to 2023 primarily due to an increase in investment income, an increase in premiums written, partially offset by an increase in underwriting and operating expenses paid, and an increase in loss payments.

 We also have purchase obligations totaling approximately $11.6 million which consist primarily of contracts related to our continued investment in our information technology infrastructure in the normal course of business. The majority of these obligations are under contracts that give us cancellation rights with notice. In the next twelve months we anticipate we will pay approximately $8.7 million for our purchase obligations.

 MGIC Investment Corporation 2024 Form 10-K | 74

 We do not expect to make a contribution to the pension plan in 2025 and distributions from the supplemental executive retirement plan will be funded as incurred. The net funded status (the market value of our plan assets compared to the projected benefit obligation) will impact future contributions to our qualified pension plan.

 Investing activities
 The following list highlights the major sources and uses of cash flow from investing activities:

 Sources

 +
 Proceeds from sales of investments

 +
 Proceeds from maturity of fixed income securities

 Uses

 -
 Purchases of investments

 We maintain an investment portfolio that is primarily invested in a diverse mix of fixed income securities. As of December 31, 2024, our portfolio had a fair value of $5.9 billion compared to $5.7 billion at December 31, 2023. Net cash flows used in investing activities in 2024 and 2023, primarily reflects purchases of fixed income securities during the period that exceeded sales and maturities of fixed income securities during the period as cash from operations was available for additional investment.

 Financing activities
 The following list highlights the major sources and uses of cash flow from financing activities:

 Sources

 +
 Proceeds from debt and/or common stock issuances

 Uses

 -
 Repayment/repurchase of debt

 -
 Repurchase of common stock

 -
 Payment of dividends to shareholders

 -
 Payment of withholding taxes related to share-based compensation net share settlement

 Net cash flows used in financing activities in 2024 primarily reflects the repurchases of our common stock, dividends to shareholders, and the payment of withholding taxes related to share-based compensation net share settlement. Net cash flows used in financing activities in 2023 primarily reflects the repurchase of our common stock, dividends to shareholders, and the conversion of our 9% Debentures.

 For a further discussion of matters affecting our cash flows, see " Balance Sheet Review " above and "Debt at our Holding Company and Holding Company Liquidity" below.

 CAPITALIZATION
 Capital Risk
 Capital risk is the risk of adverse impact on our ability to comply with capital requirements (regulatory and GSE) and to maintain the level, structure and composition of capital required for meeting financial performance objectives.

 A strong capital position is essential to our business strategy and is important to maintain a competitive position in our industry. Our capital strategy focuses on long-term stability, which enables us to build and invest in our business, even in a stressed environment.

 Our capital management objectives are to:

 influence and maintain compliance with capital requirements,

 maintain access to capital and reinsurance markets,

 manage our capital to support our business strategies and the competing priorities of relevant stakeholders

 assess appropriate uses for capital that cannot be deployed in support of our business strategies, including the size and form of capital return to shareholders, and

 support business opportunities by enabling capital flexibility and efficiently using company resources.

 These objectives are achieved through ongoing monitoring and management of our capital position, mortgage insurance portfolio stress modeling, and a capital governance framework. Capital management is intended to be flexible in order to react to a range of potential events. The focus we place on any individual objective may change over time due to factors that include, but are not limited to, economic conditions, changes at the GSEs, competition, and alternative transactions to transfer mortgage risk.

 (1)As of November 15, 2024, we retired all shares of our treasury stock. Effective November 15, 2024, all shares of our common stock that we repurchase are immediately retired and not held as treasury stock.

 The increase in shareholders' equity in 2024 primarily relates to net income and a decrease in the accumulated other comprehensive losses reported in shareholders' equity related to the fair value of our investment portfolio and net changes in our benefit plan assets and obligations. These changes were partially offset by repurchases of our common stock and dividends paid to shareholders in 2024. See Note 13 - "Shareholders' Equity" for further information.

 Debt obligations - holding company
 As of December 31, 2024, our holding company's debt obligations was $650 million in aggregate principal amount consisting of our 5.25% Notes due in 2028.

 See Note 7 - "Debt" for further information on our outstanding debt obligations and transactions impacting our consolidated financial statements in 2024 and 2023.

 Liquidity analysis - holding company
 As of December 31, 2024, and December 31, 2023, we had approximately $1.1 billion and $0.9 billion, respectively, in cash and investments at our holding company. These resources are maintained primarily to service our debt interest expense, pay debt maturities, repurchase shares, pay dividends to shareholders, and to settle intercompany obligations. While these assets are held, we generate investment income that serves to offset a portion of our cash requirements. The payment of dividends from MGIC are the principal source of holding company cash inflow and their payment is restricted by insurance regulation. See Note 14 - "Statutory Information" to our consolidated financial statement for additional information about MGIC's dividend restrictions. The payment of dividends from MGIC is also influenced by our view of the appropriate level of excess PMIERs Available Assets to maintain, which can change over time. Raising capital in the public markets is another potential source of holding company liquidity. The ability to raise capital in the public markets is subject to prevailing market conditions, investor demand for the securities to be issued, and our deemed creditworthiness.

 Over the next twelve months the principal demand on holding company resources will be interest payments on our 5.25% Notes approximating $34.0 million, based on the debt outstanding at December 31, 2024. We believe our holding company has sufficient sources of liquidity to meet its payment obligations for the foreseeable future.

 During 2024 and 2023, we repurchased 25.3 million and 21.7 million shares of our common stock for $566.6 million and $340.6 million respectively. Through February 21, 2025 we repurchased 5.8 million shares of our common stock for $142.3 million. The repurchase programs may be suspended or discontinued at any time.

 In 2024, we paid cash dividends of $130.5 million to shareholders. On January 28, 2025, our Board of Directors declared a quarterly cash dividend of $0.13 per common share to shareholders of record on February 18, 2025, payable on March 5, 2025. We expect to continue to make dividend payments to shareholders in 2025.

 We may use additional holding company cash to repurchase additional shares or to repurchase our outstanding debt obligations. Such repurchases may be material, may be made for cash (funded by debt) and/or exchanges for other securities, and may be made in open market purchases (including through 10b5-1 plans), privately negotiated acquisitions or other transactions. In 2025, we expect share repurchase programs will remain our primary means of returning capital to shareholders. See "Overview-Capital" of this MD&A for a discussion of our share repurchase programs.

 Significant cash and investments inflows at our holding company during the year were:
 •$750.0 million dividends received from MGIC,
 •$44.4 million intercompany tax receipts,
 •$40.0 million of capital returned from our subsidiary, and
 •$29.5 million of investment income.

 MGIC Investment Corporation 2024 Form 10-K | 76

 Significant cash outflows at our holding company during the year were:
 •$569.5 million of net share repurchase transactions,
 •$130.5 million of cash dividends paid to shareholders, and
 •$34.1 million of interest payments on our outstanding debt obligations

 The net unrealized losses on our holding company investment portfolio were approximately $3.4 million at December 31, 2024 and the portfolio had a modified duration of approximately 0.8 years.

 MGIC paid $750 million in dividends to our holding company in the year ended December 31, 2024. Future dividend payments from MGIC to the holding company will be determined in consultation with the Board of Directors, and after considering any updated estimates about our business. We ask the Wisconsin OCI not to object before MGIC pays dividends to the holding company.

 Scheduled debt maturities beyond the next twelve months include $650 million of our 5.25% Notes in 2028.

 See Note 7 – "Debt" to our consolidated financial statements for additional information about our long term debt. The description in Note 7 - "Debt" to our consolidated financial statements is qualified in its entirety by the terms of the notes and debentures. The terms of our 5.25% Notes are contained in a Supplemental Indenture, dated as of August 12, 2020, between us and U.S. Bank National Association, as trustee, which is included as an exhibit to our 8-K filed with the SEC on August 12, 2020, and in the Indenture dated as of October 15, 2000 between us and the trustee.

 Although not anticipated in the near term, we may also contribute funds to our insurance operations to comply with the PMIERs or the State Capital Requirements. See " Overview – Capital " above for a discussion of these requirements.

 DEBT AT SUBSIDIARIES
 MGIC did not have any outstanding debt obligations at December 31, 2024. MGIC is a member of the FHLB, which provides MGIC access to an additional source of liquidity through a secured lending facility. We may borrow from the FHLB at any time.

 CAPITAL ADEQUACY
 PMIERs
 As of December 31, 2024, MGIC's Available Assets under the PMIERs totaled approximately $5.8 billion, an excess of approximately $2.2 billion over its Minimum Required Assets; and MGIC is in compliance with the requirements of the PMIERs and eligible to insure loans delivered to or purchased by the GSEs.

Our 2025 and 2026 QSR Transaction is a 40% quota share on most of our new insurance written in 2025 and 2026, respectively, and will also provide PMIERs capital credit. Refer to Note 9 - "Reinsurance" to our consolidated financial statements for additional information on our reinsurance transactions.

 The PMIERs generally require us to hold significantly more Minimum Required Assets for delinquent loans than for performing loans and the Minimum Required Assets required to be held increases as the number of payments missed on a delinquent loan increases. Refer to " Overview - Capital - GSEs " of this MD&A and our risk factor titled "We may not continue to meet the GSEs' private mortgage insurer eligibility requirements and our returns may decrease if we are required to maintain more capital in order to maintain our eligibility" in Item 1A. for further discussion of PMIERs.

 We plan to continuously comply with the PMIERs through our operational activities or through the contribution of funds from our holding company, subject to demands on the holding company's resources, as outlined above.

 MGIC Investment Corporation 2024 Form 10-K | 77

 RISK-TO-CAPITAL
 We compute our risk-to-capital ratio on a separate company statutory basis, as well as on a combined insurance operations basis. The risk-to-capital ratio is our net RIF divided by our policyholders' position. Our net RIF includes both primary and pool RIF and excludes risk on policies that are currently in default and for which case loss reserves have been established and the risk covered by reinsurance. The risk amount includes pools of loans with contractual aggregate loss limits and without these limits. MGIC's policyholders' position consists primarily of statutory policyholders' surplus (which increases as a result of statutory net income and decreases as a result of statutory net loss and dividends paid), plus the statutory contingency reserve. The statutory contingency reserve is reported as a liability on the statutory balance sheet. A mortgage insurance company is required to make annual additions to a contingency reserve of approximately 50% of earned premiums. These contributions must generally be maintained for a period of ten years. However, with regulatory approval a mortgage insurance company may make early withdrawals from the contingency reserve when incurred losses exceed 35% of earned premiums in a calendar year.

 The increase in statutory policyholders' position was primarily due to an increase in net income in 2024, offset by a decrease in statutory contingency reserves and dividends paid to our holding company of $750 million. Our risk-to-capital ratio will increase if the percentage increase in capital exceeds the percentage decrease in insured risk.

 For additional information regarding regulatory capital see Note 14 – "Statutory Information" to our consolidated financial statements as well as our risk factor titled "State capital requirements may prevent us from continuing to write new insurance on an uninterrupted basis" in Item 1A.

 CRITICAL ACCOUNTING ESTIMATES
 The accounting estimate described below requires significant judgments and estimates in the preparation of our consolidated financial statements.

 LOSS RESERVES
 The estimation of case loss reserves is subject to inherent uncertainty and requires significant judgement by management. Changes to our estimates could result in a material impact to our consolidated results and financial position, even in a stable economic environment.

 Case Reserves
 Case reserves are established for estimated insurance losses when notices of delinquency on insured mortgage loans are received. Such loans are referred to as being in our delinquency inventory. For reporting purposes, we consider a loan delinquent when it is two or more payments past due and has not become current or resulted in a claim payment. Although the accounting standard, ASC 944, regarding accounting and reporting by insurance entities specifically excluded mortgage insurance from its guidance relating to loss reserves, we establish loss reserves using the general principles contained in the insurance standard. However, consistent with industry standards for mortgage insurers, we do not establish case loss reserves for future claims on insured loans which are not currently delinquent.

 We establish reserves using estimated claim rates and claim severities in estimating the ultimate loss.

 The estimated claim rates and claim severities are used to determine the amount we estimate will actually be paid on the delinquent loans as of the reserve date. If a policy is rescinded we do not expect that it will result in a claim payment and thus the rescission generally reduces the historical claim rate used in establishing reserves. In addition, if a loan cures its delinquency, including through a successful loan modification, the cure reduces the historical claim rate used in establishing reserves. To establish reserves, we utilize a reserving model that continually incorporates historical data into the estimated claim rate. The model also incorporates an estimate for severity. The severity is estimated using the historical percentage of our claims paid compared to our loan exposures, as well as the RIF of the loans currently in default. We do not utilize an explicit rescission rate in our reserving methodology, but rather our reserving methodology incorporates the effects rescission activity has had on our historical claim rate and claim severities. We review recent trends in the claim rate, claim severity, levels of defaults by geography and average loan exposure. As a result, the process to determine reserves does not include quantitative ranges of outcomes that are reasonably likely to occur.

 The claim rates and claim severities are affected by external events, including actual economic conditions such as changes in unemployment rates, interest rates or housing values, pandemics and natural disasters. Our estimation process does not include a correlation between claim rates and claim severities to projected economic conditions such as changes in unemployment rates, interest rates or housing values. Our experience is that analysis of that nature would not produce reliable results as the change in one economic condition cannot be isolated to determine its specific effect on our ultimate paid losses because each economic condition is also influenced by other economic conditions. Additionally, the changes and interactions of these economic conditions are not likely homogeneous throughout the regions in which we conduct business. Each economic condition influences our ultimate paid losses differently, even if apparently similar in nature. Furthermore, changes in economic conditions may not necessarily be reflected in our loss development in the quarter or year in which the changes occur. Actual claim results generally lag changes in economic conditions by at least nine to twelve months.

 Our estimate of loss reserves is sensitive to changes in claim rate and claim severity; it is possible that even a relatively small change in our estimated claim rate or claim severity could have a material impact on reserves and, correspondingly, on our consolidated results of operations even in a stable economic environment. For example, as of December 31, 2024, assuming all other factors remain constant, a $1,000 increase/decrease in the average claim severity reserve factor would change the reserve amount by approximately +/- $7 million. A one percentage point increase/decrease in the average claim rate reserve factor would change the reserve amount by approximately +/- $18 million.

 MGIC Investment Corporation 2024 Form 10-K | 79

 Historically, it has not been uncommon for us to experience variability in the development of the loss reserves through the end of the following year at this level or higher, as shown by the historical development of our loss reserves in the table below:

 Item 7A. Quantitative and Qualitative Disclosures About Market Risk

 Our investment portfolio is essentially a fixed income portfolio and is exposed to market risk. Important drivers of the market risk are credit spread risk and interest rate risk.

 Credit spread risk is the risk that we will incur a loss due to adverse changes in credit spreads. Credit spread is the additional yield on fixed income securities above the risk-free rate (typically referenced as the yield on U.S. Treasury securities) that market participants require to compensate them for assuming credit, liquidity and/or prepayment risks.

 We manage credit risk via our investment policy guidelines which primarily require us to place our investments in investment grade securities and limit the amount of our credit exposure to any one issue, issuer and type of instrument. Guideline and investment portfolio detail is available in "Business – Section C, Investment Portfolio" in Item 1.

 Interest rate risk is the risk that we will incur a loss due to adverse changes in interest rates relative to the characteristics of our interest bearing assets.

 One of the measures used to quantify this exposure is effective duration. Effective duration measures the price sensitivity of the assets to the changes in spreads. At December 31, 2024, the effective duration of our fixed income investment portfolio was 3.9 years, which means that an instantaneous parallel shift in the yield curve of 100 basis points would result in a change of 3.9% in the fair value of our fixed income portfolio. For an upward shift in the yield curve, the fair value of our portfolio would decrease and for a downward shift in the yield curve, the fair value would increase. A discussion of portfolio strategy appears in "Management's Discussion and Analysis – Balance Sheet Review– Investment Portfolio" in Item 7.

 Note 1. Nature of Business
 MGIC Investment Corporation is a holding company which, through Mortgage Guaranty Insurance Corporation ("MGIC"), is principally engaged in the mortgage insurance business. We provide mortgage insurance to lenders throughout the United States and to government sponsored entities to protect against loss from defaults on low down payment residential mortgage loans. Primary mortgage insurance provides mortgage default protection on individual loans and covers a percentage of the unpaid loan principal, delinquent interest and certain expenses associated with the default and subsequent foreclosure or sale approved by us, of the underlying property. MGIC Assurance Corporation ("MAC") and MGIC Indemnity Corporation ("MIC"), insurance subsidiaries of MGIC, provide insurance for certain mortgages under Fannie Mae and Freddie Mac (the "GSEs") credit risk transfer programs. We operate as a single segment for the purposes of evaluating financial performance and allocating resources.

 At December 31, 2024, our direct primary insurance in force ("IIF") was $ 295.4 billion, which represents the unpaid principal balance, either estimated by us or reported to us by mortgage servicers, for the loans we insure, and our direct primary risk in force ("RIF") was $ 78.8 billion, which represents the IIF multiplied by the insurance coverage percentage.

 The substantial majority of our new insurance written ("NIW") is for loans purchased by the GSEs. The current private mortgage insurer eligibility requirements ("PMIERs") of the GSEs include financial requirements, as well as business, quality control and certain transactional approval requirements. The financial requirements of the PMIERs require a mortgage insurer's "Available Assets" (generally only the most liquid assets of an insurer) to equal or exceed its "Minimum Required Assets" (which are based on an insurer's book of risk in force, calculated from tables of factors with several risk dimensions). Based on our application of the PMIERs, as of December 31, 2024, MGIC's Available Assets are in excess of its Minimum Required Assets, and MGIC is in compliance with the PMIERs and eligible to insure loans purchased by the GSEs.

 Note 2. Basis of Presentation
 BASIS OF PRESENTATION
 The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"), as codified in the Accounting Standards Codification ("ASC"). Our consolidated financial statements include the accounts of MGIC Investment Corporation and its subsidiaries. Intercompany transactions and balances have been eliminated. In accordance with GAAP, we are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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 periods. Actual results could differ from those estimates.

 SUBSEQUENT EVENTS
 We have considered subsequent events through the date of this filing.

 MGIC Investment Corporation 2024 Form 10-K | 88

 Note 3. Significant Accounting Policies
 CASH AND CASH EQUIVALENTS
 We consider money market funds and investments with original maturities of three months or less to be cash equivalents.

 RESTRICTED CASH AND CASH EQUIVALENTS
 Restricted cash and cash equivalents consists of cash and money market funds held in trusts for the benefit of contractual counterparties under reinsurance agreements or for other contractual restrictions.

 FAIR VALUE MEASUREMENTS
 We carry certain financial instruments at fair value and disclose the fair value of all financial instruments. Our financial instruments carried at fair value are predominantly measured on a recurring basis. Financial instruments measured on a nonrecurring basis are subject to fair value adjustments only in certain circumstances (for example, when there is evidence of impairment).

 The fair value of an asset or liability is defined as the price that would be received upon a sale of an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. Fair value is based on quoted market prices or inputs, where available. If prices or quotes are not available, fair value is based on valuation models or other valuation techniques that consider relevant transaction characteristics (such as maturity) and use as inputs observable or unobservable market parameters including yield curves, interest rates, volatilities, equity or debt prices, and credit curves. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value, as described below.

 As of December 31, 2024 and 2023, we did not elect to measure any financial instruments acquired, or issued, such as our outstanding debt obligations, at fair value for which the primary basis of accounting is not fair value.

 Valuation process
 We use independent pricing sources to determine the fair value of a substantial majority of our financial instruments, which primarily consist of assets in our investment portfolio, but also includes cash and cash equivalents and restricted cash and cash equivalents. A variety of inputs are used; in approximate order of priority, they are benchmark yields, reported trades, broker/dealer quotes, issuer spreads, bids, offers, and reference data including market research publications.

 Market indicators, industry, and economic events are also considered.

 The inputs listed above are evaluated using a multidimensional pricing model. This model combines all inputs to arrive at a value assigned to each security. Quality controls are performed by the independent pricing sources throughout this process, which include reviewing tolerance reports, trading information, data changes, and directional moves compared to market moves.

 On a quarterly basis, we perform quality controls over values received from the pricing sources which also include reviewing tolerance reports, data changes, and directional moves compared to market moves. We have not made any adjustments to the prices obtained from the independent pricing sources.

 Valuation hierarchy
 A three-level valuation hierarchy has been established under GAAP for disclosure of fair value measurements. The valuation hierarchy is based on the transparency of inputs to the valuation of a financial instrument as of the measurement date. To determine the fair value of securities available-for-sale in Level 1 and Level 2 of the fair value hierarchy, independent pricing sources, as described below, have been utilized. One price is provided per security based on observable market data. To ensure securities are appropriately classified in the fair value hierarchy, we review the pricing techniques and methodologies of the independent pricing sources and believe that their policies adequately consider market activity, either based on specific transactions for the issue valued or based on modeling of securities with similar credit quality, duration, yield and structure that were recently traded.

 The three levels are defined as follows:

 Quoted prices for identical instruments in active markets that we can access. Financial assets using Level 1 inputs primarily include U.S. Treasury securities, money market funds, treasury bills, and certain equity securities.

 Level 2
 Quoted prices for similar instruments in active markets that we can access; quoted prices for identical or similar instruments in markets that are not active; and inputs, other than quoted prices, that are observable in the marketplace for the instrument. The observable inputs are used in valuation models to calculate the fair value of the instruments. Financial assets using Level 2 inputs primarily include obligations of U.S. government corporations and agencies, corporate bonds, mortgage-backed securities, asset-backed securities, most municipal bonds, and commercial paper.

The independent pricing sources used for our Level 2 investments vary by type of investment. See Note 6 - "Fair Value Measurements" for further information.

 MGIC Investment Corporation 2024 Form 10-K | 89

 Level 3
 Valuations derived from valuation techniques in which one or more significant inputs or value drivers are unobservable. The inputs used to derive the fair value of Level 3 securities reflect our own assumptions about the assumptions a market participant would use in pricing an asset or liability. Our non-financial assets that are classified as Level 3 securities consist of real estate acquired through claim settlement and embedded derivatives related to our Home Re Transactions. The fair value of real estate acquired is the lower of our acquisition cost or a percentage of the appraised value. The percentage applied to the appraised value is based upon our historical sales experience adjusted for current trends. The fair value of our embedded derivatives reflects the present value impact of the variation in investment income on the assets held by the reinsurance trusts and the contractual reference rate on Home Re Transactions used to calculate the reinsurance premiums we estimate we will pay over the estimated remaining life.

 INVESTMENTS
 Fixed income securities. Our fixed income securities are classified as available-for-sale and are reported at fair value. Fixed income securities with original maturities less than one year and greater than three months are classified as short-term on our consolidated balance sheet. The related unrealized investment gains or losses are, after considering the related tax expense or benefit, recognized as a component of accumulated other comprehensive income (loss) in shareholders' equity. Realized investment gains and losses on fixed income securities are reported in income based upon specific identification of securities within "Net gains (losses) on investments and other financial instruments" on the consolidated statement of operations, along with any changes in the credit allowance.

 Equity securities. Equity securities are reported at fair value, except for certain securities that are carried at cost. Equity securities carried at cost are reported as Other invested assets. Realized investment gains and losses on equity securities are reported in income based upon specific identification of securities sold within "Net gains (losses) on investments and other financial instruments" on the consolidated statement of operations, along with any changes in the fair value.

 Other invested assets. Other invested assets are carried at cost. These assets represent our investment in Federal Home Loan Bank of Chicago ("FHLB") stock, which due to restrictions, is required to be redeemed or sold only to the security issuer at par value.

 Accrued Investment Income. We report accrued investment income separately from securities. Accrued investment income is written off through net realized investment gains (losses) if, and at the time, the issuer of the security defaults or is expected to default on payments.

 Unrealized losses and allowance for credit losses
 Each quarter we determine whether securities in an unrealized loss position are impaired by considering several factors including, but not limited to:

 our intent to sell the security or whether it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis;

 the present value of the discounted cash flows we expect to collect compared to the amortized cost basis of the security;

 failure of the issuer to make scheduled interest or principal payments;

 a change in rating to below investment grade; and

 adverse conditions specifically related to the security, an industry, or a geographic area.

 Based on our evaluation, we will record an impairment on a security if we intend to sell, if it is more likely than not that we will be required to sell it prior to recovery of its amortized cost basis, or if the present value of the discounted cash flows we expect to collect is less than the amortized cost basis of the security.

 When a security is considered to be impaired, but when a sale is not intended or is not likely, the loss is separated into the portion that represents the credit loss and the portion that is due to other factors. A credit loss is recorded, subject to reversal, in the consolidated statement of operations within "Net gains (losses) on investments and other financial instruments." The loss due to other factors is recognized in accumulated other comprehensive loss, net of taxes. A credit loss is determined to exist if the present value of the discounted cash flows, using the security's original yield, expected to be collected from the security is less than the cost basis of the security.

 HOME OFFICE AND EQUIPMENT
 Home office and equipment is carried at cost, net of depreciation. For financial reporting purposes, depreciation is determined on a straight-line basis for the home office and equipment over estimated lives ranging from 3 to 45 years. For income tax purposes, we use accelerated depreciation methods.

 Home office and equipment is shown net of accumulated depreciation of $ 61.2 million and $ 59.2 million as of December 31, 2024 and 2023, respectively. Depreciation expense for the years ended December 31, 2024, 2023 and 2022 was $ 4.2 million, $ 4.6 million and $ 4.9 million, respectively.

 MGIC Investment Corporation 2024 Form 10-K | 90

 DEFERRED INSURANCE POLICY ACQUISITION COSTS
 Costs directly associated with the successful acquisition of mortgage insurance business, consisting of employee compensation and other policy issuance and underwriting expenses, are initially deferred and reported as deferred insurance policy acquisition costs ("DAC"). The deferred costs are reported net of any ceding commissions received associated with our reinsurance transactions. For each underwriting year of business, these costs are amortized to income in proportion to estimated gross profits over the estimated life of the policies. The estimates for each underwriting year are reviewed quarterly and updated when necessary to reflect actual experience and any changes to key variables such as persistency or loss development.

 LOSS RESERVES
 Loss reserves include case reserves, incurred but not reported ("IBNR") reserves, and loss adjustment expense ("LAE") reserves.

 Case reserves and LAE reserves are established when notices of delinquency on insured mortgage loans are received. Such loans are referred to as being in our delinquency inventory. For reporting purposes, we consider a loan delinquent when it is two or more payments past due and has not become current or resulted in a claim payment. Although the accounting standard, ASC 944, regarding accounting and reporting by insurance entities specifically excludes mortgage insurance from its guidance relating to loss reserves, we establish loss reserves using the general principles contained in the insurance standard. However, consistent with industry standards for mortgage insurers, we do not establish case reserves for future claims on insured loans that are not currently delinquent.

 Case reserves are established by estimating the number of loans in our delinquency inventory that will result in a claim payment, which is referred to as the claim rate, and further estimating the amount of the claim payment, which is referred to as claim severity. Our case reserve estimates are primarily established based upon historical experience, including rescissions of policies, curtailments of claims, and loan modification activity. Adjustments to reserve estimates are reflected in the financial statements in the years in which the adjustments are made. Loss reserves for reinsurance assumed are based on information provided by the ceding companies.

 IBNR reserves are established for delinquencies estimated to have occurred prior to the close of an accounting period, but have not yet been reported to us. Consistent with case reserves for reported delinquencies, IBNR reserves are also established using estimated claim rates and claim severities.

 LAE reserves are established for the estimated costs of settling claims, including legal and other expenses, and general expenses of administering the claims settlement process.

 Loss reserves are ceded to reinsurers under our reinsurance agreements. (See "Reinsurance" discussion below. Also see Note 8 – "Loss Reserves" and Note 9 – "Reinsurance.")

 PREMIUM DEFICIENCY RESERVE
 After our loss reserves are established, we perform premium deficiency tests using our best estimate of future premium, losses and LAE paid. Premium deficiency reserves are established, if necessary, when the present value of expected future losses and LAE paid exceeds the present value of expected future premium, anticipated investment income, and already established loss reserves.

 REVENUE RECOGNITION
 We write policies which are guaranteed renewable at the insured's option on a monthly, single, or annual premium basis. We have no ability to re-underwrite or reprice these policies. Premiums written on monthly premium policies are earned as coverage is provided. Premiums written on single premium policies and annual premium policies are initially deferred as unearned premium reserve. Premiums written on annual premium policies are earned on a monthly pro rata basis. Premiums written on policies covering more than one year are amortized over the estimated policy life based on historical experience, which includes the anticipated incurred loss pattern. When a policy is cancelled for a reason other than rescission or claim payment, all premium that is non-refundable is immediately earned. Any refundable premium is returned to the servicer or borrower. When a policy is cancelled due to rescission, all previously collected premium is returned. When a policy is cancelled because a claim is paid, premium collected since the date of delinquency is returned.

 The liability associated with our estimate of premium to be returned is accrued for separately and included in "Other liabilities" on our consolidated balance sheets. Changes in this liability, and the actual return of premiums for all periods, affect premiums written and earned.

 We assess whether a credit loss allowance is required for our premium receivable. We consider collectability trends and industry development, among other things. Any estimated credit loss would be immediately recognized.

 Fee income of our non-insurance subsidiaries is earned and recognized as the services are provided and the customer is obligated to pay. Fee income consists primarily of contract underwriting and related fee-based services provided to lenders and is included in "Other revenue" on the consolidated statements of operations.

 MGIC Investment Corporation 2024 Form 10-K | 91

 INCOME TAXES
 Deferred income taxes are provided under the liability method, which recognizes the future tax effects of temporary differences between amounts reported in the consolidated financial statements and the tax bases of these items. The estimated tax effects are computed at the enacted federal statutory income tax rate. Changes in tax laws, rates, regulations, and policies or the final determination of tax audits or examinations, could materially affect our estimates and can be significant to our operating results. We evaluate the realizability of the deferred tax assets based on the weight of all available positive and negative evidence. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that all or some portion of the deferred tax assets will not be realized.

 The recognition of a tax position is determined using a two-step approach. The first step applies a more-likely-than-not threshold for recognition and derecognition. The second step measures the tax position as the greatest amount of benefit that is cumulatively greater than 50% likely to be realized. When evaluating a tax position for recognition and measurement, we presume that the tax position will be examined by the relevant taxing authority that has full knowledge of all relevant information. We recognize interest accrued and penalties related to unrecognized tax benefits in our provision for income taxes.

 Federal tax law permits mortgage guaranty insurance companies to deduct from taxable income, subject to certain limitations, the amounts added to contingency loss reserves that are recorded for regulatory purposes. The amounts we deduct must generally be included in taxable income in the tenth subsequent year. The deduction is allowed only to the extent that we purchase and hold U.S. government non-interest-bearing tax and loss bonds in an amount equal to the tax benefit attributable to the deduction. We account for these purchases as a payment of current federal income tax. (See "Note 12 - Income Taxes.")

 BENEFIT PLANS
 We have a non-contributory defined benefit pension plan, as well as a supplemental executive retirement plan, that covered eligible employees as of December 31, 2022, utilizing a cash balance formula. Effective January 1, 2023, these plans were frozen (no future benefits will be accrued for participants due to employment and no new participants will be added). Participants will continue to earn interest credits on their retirement benefits. We recognize the ongoing retirement benefit costs of these plans as they are incurred. Our policy is to fund pension costs as required under the Employee Retirement Income Security Act of 1974.

 We also offer benefits for retired domestic employees, their eligible spouses and dependents under a postretirement benefit plan. Participation in this plan is limited to eligible employees that participated in the defined benefit pension plan. Eligibility for coverage is based on meeting certain years of service and retirement age qualifications. We accrue the estimated costs of the retiree benefits over the period during which employees render the service that qualifies them for benefits. (See Note 11 – "Benefit Plans.")

 REINSURANCE
 We cede insurance risk through the use of quota share reinsurance transactions ("QSR") and excess of loss reinsurance transactions. We have excess of loss transactions executed through the traditional reinsurance market and with Home Re special purpose insurers. Premiums and losses incurred on our QSR Transactions are ceded pursuant to the terms of our reinsurance agreements. Reinsurance premiums ceded under our traditional reinsurance transactions are based off the remaining reinsured coverage levels. Reinsurance premiums ceded under our Home Re agreements are composed of coverage, initial expense and supplemental premiums. The coverage premiums are generally calculated as the difference between the amount of interest payable by the Home Re Entity on the remaining reinsurance coverage levels, and the investment income collected on the collateral assets held in the reinsurance trust account and used to collateralize the Home Re Entity's reinsurance obligation to MGIC.

 Loss reserves are reported before taking credit for amounts ceded under reinsurance transactions. Ceded loss reserves are reflected as "Reinsurance recoverable on loss reserves." Amounts due from reinsurers on paid claims are reflected as "Reinsurance recoverable on paid losses." Ceded premiums payable, net of ceding commission and profit commission are included in "Other liabilities." Profit commissions are included with "Premiums written – Ceded" and ceding commissions are included with "Other underwriting and operating expenses, net." We remain liable for all insurance ceded. (See Note 9 – "Reinsurance.")

 We assess whether a credit loss allowance is required for our reinsurance recoverables. In assessing whether a credit allowance should be established, we consider several factors including, but not limited to, the credit ratings of individual reinsurers, investor reports for our Home Re Transactions, collateral held in trust accounts in which MGIC is the sole beneficiary, and aging of outstanding reinsurance recoverable balances.

 Assumed reinsurance is based on information received from the ceding company.

 See Note 9 – "Reinsurance " for discussion of our variable interest entity ("VIE") policy on the Home Re Transactions.

 SHARE-BASED COMPENSATION
 We have certain share-based compensation plans. Under the fair value method, compensation cost is measured at the grant date based on the fair value of the award and is recognized over the service period which generally corresponds to the vesting period. Awards under our plans generally vest over periods ranging from one to three years, although awards to our non-employee directors vest immediately. Any forfeitures of awards are recognized as they occur. (See Note 15 – "Share-based Compensation Plans.")

 MGIC Investment Corporation 2024 Form 10-K | 92

 EARNINGS PER SHARE
 Basic earnings per share ("EPS") is calculated by dividing net income by the weighted average number of shares of common stock outstanding. Our "participating securities" are composed of vested restricted stock and restricted stock units ("RSUs") with non-forfeitable rights to dividends. Diluted EPS includes the components of basic EPS and also gives effect to dilutive common stock equivalents. We calculate diluted EPS using the treasury stock method and if-converted method. Under the treasury stock method, diluted EPS reflects the potential dilution that could occur if our unvested restricted stock units result in the issuance of common stock. Prior to our redemption of the outstanding principal on our 9% debentures in 2023, we utilized the if-converted method, to calculate the potential dilution that could occur if our 9% Debentures were converted to common stock. The determination of potentially issuable shares did not consider the satisfaction of the conversion requirements and the shares were included in the determination of diluted EPS as of the beginning of the period, if dilutive. For purposes of calculating basic and diluted EPS, vested RSUs are considered outstanding. In 2023, under the terms of our 9% Debentures, we exercised our option to redeem the outstanding principal. (See Note 7 - "Debt".)

 RELATED PARTY TRANSACTIONS
 In 2024, 2023, and 2022 there were no material related party transactions.

 RECENT ACCOUNTING AND REPORTING DEVELOPMENTS
 Accounting standards and laws and regulations effective in 2024 or early adopted, and relevant to our financial statements are described below:

 Segment Reporting—Improvements to Reportable Segment Disclosures: ASU 2023-07
 In November 2023, the FASB issued ASU 2023-07. The update expands annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. The standard took effect for all public business entities for fiscal periods beginning after December 15, 2023, and interim periods beginning after December 31, 2024. The Company adopted ASU 2023-07 during the year ended December 31, 2024. See Note 18 - "Segment Reporting" for our disclosures around ASU 2023-07.

 PROSPECTIVE ACCOUNTING AND REPORTING DEVELOPMENTS
 Relevant new amendments to accounting standards, which are not yet effective or adopted.

 Improvements to Income Tax Disclosures: ASU 2023-09
 In December 2023, the FASB issued ASU 2023-09 to enhance the transparency and decision usefulness of income tax disclosures. Income tax disclosures will require consistent categories and greater disaggregations of information in the rate reconciliation and disclosure of income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024 on a prospective basis. We have evaluated the impacts the adoption of this guidance will have on our consolidated financial statements and determined that it will not have a material impact.

 Disaggregation of Income Statement Expenses: ASU 2024-03
 In November 2024, the FASB issued ASU 2024-03 requiring additional disclosure of the nature of expenses included in the income statement. The new standard requires disclosures about specific expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. The requirements will be applied prospectively with the option for retrospective application. Early adoption is permitted. We are currently evaluating the impacts the adoption of this guidance will have on our disclosures, but do not expect it to have a material impact.

Under this method, if dilutive, the common stock related to the outstanding 9% Debentures was assumed to be issued as of the beginning of the reporting period and the related interest expense, net of tax, was added back to earnings in calculating diluted EPS. In 2023, under the terms of our 9% Debentures, we exercised our option to redeem the outstanding principal. (See Note 7 - "Debt".)

 We had $ 12.2 million of investments at fair value on deposit with various states as of December 31, 2024 and 2023, in accordance with regulatory requirements of those state insurance departments.

 In connection with our insurance and reinsurance activities within MAC and MIC, we are required to maintain assets in trusts for the benefit of contractual counterparties, which had investments at fair value of $ 199.9 million and $ 156.9 million at December 31, 2024 and 2023, respectively. The increase is primarily due to an increase in collateral required as the risk in force covered by these insurance and reinsurance activities has increased.

 The amortized cost and fair values of fixed income securities at December 31, 2024, by contractual maturity, are shown in table 5.2 below. Actual maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Because most mortgage and asset-backed securities provide for periodic payments throughout their lives, they are listed in separate categories.

 There were 1,020 and 1,021 securities in an unrealized loss position as of December 31, 2024 and 2023, respectively. Based on current facts and circumstances, we believe the unrealized losses as of December 31, 2024 presented in table 5.5a above are not indicative of the ultimate collectability of the par value of the securities. The unrealized losses in all categories of our investments were primarily caused by an increase in prevailing interest rates. We also rely upon estimates of several credit and non-credit factors in our review and evaluation of individual investments to determine whether a credit impairment exists. All of the securities in an unrealized loss position are current with respect to their interest obligations.

 Note 6. Fair Value Measurements
 Recurring fair value measurements
 The following describes the valuation methodologies generally used by the independent pricing sources, or by us, to measure financial instruments at fair value, including the general classification of such financial instruments pursuant to the valuation hierarchy.

 • Fixed income securities:
 U.S. Treasury Securities and Obligations of U.S. Government Corporations and Agencies: Securities with valuations derived from quoted prices for identical instruments in active markets that we can access are categorized in Level 1 of the fair value hierarchy. Securities valued by surveying the dealer community, obtaining relevant trade data, benchmark quotes and spreads and incorporating this information in the valuation process are categorized as Level 2 of the fair value hierarchy.
 Corporate Debt Securities are valued by obtaining relevant trade data, benchmark quotes and spread, and broker/dealer quotes and incorporating this information into the valuation process. These securities are generally categorized in Level 2 of the fair value hierarchy.
 Obligations of U.S. States & Political Subdivisions are valued by tracking, capturing, and analyzing quotes for active issues and trades reported via the Municipal Securities Rulemaking Board records. Daily briefings and reviews of current economic conditions, trading levels, spread relationships, and the slope of the yield curve provide further data for evaluation. These securities are generally categorized in Level 2 of the fair value hierarchy.
 Residential Mortgage-Backed Securities ("RMBS") are valued by monitoring interest rate movements, and other pertinent data daily. Incoming market data is enriched to derive spread, yield and/or price data as appropriate, enabling known data points to be extrapolated for valuation application across a range of related securities. These securities are generally categorized in Level 2 of the fair value hierarchy.
 Commercial Mortgage-Backed Securities ("CMBS") are valued using techniques that reflect market participants' assumptions and maximize the use of relevant observable inputs including quoted prices for similar assets, benchmark yield curves and market corroborated inputs. Evaluation uses regular reviews of the inputs for securities covered, including executed trades, broker quotes, credit information, collateral attributes and/or cash flow waterfall as applicable. These securities are generally categorized in Level 2 of the fair value hierarchy.
 Asset-Backed Securities ("ABS") are valued using spreads and other information solicited from market buy-and-sell-side sources, including primary and secondary dealers, portfolio managers, and research analysts. Cash flows are generated for each tranche, benchmark yields are determined, and deal collateral performance and tranche level attributes including trade activity, bids, and offers are applied, resulting in tranche specific prices. These securities are generally categorized in Level 2 of the fair value hierarchy.
 Collateralized loan obligations ("CLOs") are valued by evaluating manager rating, seniority in the capital structure, assumptions about prepayment, default and recovery and their impact on cash flow generation. Loan level net asset values are determined and aggregated for tranches and as a final step prices are checked against available recent trade activity. These securities are generally categorized in Level 2 of the fair value hierarchy.
 Foreign government debt is valued by surveying the dealer community, obtaining relevant trade data, benchmark quotes and spreads and incorporating this information into the valuation process. These securities are generally categorized in Level 2 of the fair value hierarchy.
 Commercial Paper, with an original maturity greater than 90 days, is valued using market data for comparable instruments of similar maturity and average yields. These securities are categorized in Level 2 of the fair value hierarchy.
 • Equity securities: Consist of actively traded, exchange-listed equity securities, including exchange traded funds ("ETFs") and Bond Mutual Funds, with valuations derived from quoted prices for identical assets in active markets that we can access. These securities are valued in Level 1 of the fair value hierarchy.
 • Cash Equivalents: Consists of money market funds and treasury bills with valuations derived from quoted prices for identical assets in active markets that we can access. These securities are valued in level 1 of the fair value hierarchy. Instruments in this category valued using market data for comparable instruments are classified as level 2 in the fair value hierarchy.

 MGIC Investment Corporation 2024 Form 10-K | 99

 Assets measured at fair value, by hierarchy level, as of December 31, 2024 and 2023 are shown in tables 6.1a and 6.1b below. The fair value of the assets is estimated using the process described above, and more fully in Note 3 - "Significant Accounting Policies" to the consolidated financial statements in this Form 10-K.

 Certain financial instruments, including insurance contracts, are excluded from these fair value disclosure requirements. Additional fair value disclosures related to our investment portfolio are included in Note 5 - "Investments."

 In addition to the assets carried at fair value discussed above, we have embedded derivatives carried at fair value related to our Home Re Transactions that are classified as Other liabilities or Other assets in our consolidated balance sheets. The estimated fair value related to our embedded derivatives reflects the present value impact of the variation in investment income on the assets held by the reinsurance trusts and the contractual reference rate on the Home Re Transactions used to calculate the reinsurance premiums we estimate we will pay over the estimated remaining life. These liabilities or assets are categorized in Level 3 of the fair value hierarchy. At December 31, 2024 and 2023, the fair value of the embedded derivatives was a liability of $ 0.4 million and an asset of $ 2.4 million, respectively. (See Note 9 - "Reinsurance" for more information about our Home Re Transactions.)

 Real estate acquired through claim settlement is carried at fair values and is reported in "Other assets" on the consolidated balance sheet. These assets are categorized as Level 3 of the fair value hierarchy. Purchases of real estate acquired was $ 5.2 million and

 MGIC Investment Corporation 2024 Form 10-K | 100

 $ 0.6 million for the years ended December 31, 2024, and 2023, respectively. Sales of real estate acquired were $ 2.7 million and $ 3.8 million for the years ended December 31, 2024, and 2023, respectively.

 FINANCIAL ASSETS AND LIABILITIES NOT MEASURED AT FAIR VALUE
 Other invested assets include an investment in FHLB stock that is carried at cost, which due to restrictions that require it to be redeemed or sold only to the security issuer at par value, approximates fair value. The fair value of other invested assets is categorized as Level 2.

 Financial liabilities include our outstanding debt obligation. The fair value of our 5.25 % Notes is based on observable market prices. In all cases the fair values of the financial liabilities below are categorized as level 2.

 Table 6.2 presents the carrying value and fair value of our financial assets and liabilities disclosed, but not carried, at fair value as of December 31, 2024 and 2023.

 DEBT OBLIGATIONS
 The aggregate carrying value of our 5.25% Senior Notes (" 5.25 % Notes") and the par value as of December 31, 2024 and 2023 is presented in table 7.1 below.

 2023

 5.25% Notes, due August 2028 (par value: $ 650 million)

 $
 $

 The 5.25 % Senior Notes are an obligation of our holding company, MGIC Investment Corporation.

 2023 Transactions
 In the third quarter of 2023, under the terms of our 9 % Debentures, we exercised our option to redeem the outstanding principal of $ 21.1 million. The 9% Debentures were convertible into shares of MGIC common stock at a rate of 77.9620 shares per $ 1,000 principal amount. Prior to the redemption date, substantially all holders elected to convert into shares of common stock. Under the terms of the 9% Debentures, we paid cash of $ 28.6 million in lieu of issuing shares of common stock. The conversion of our 9% Debentures resulted in a $ 5.3 million reduction in our shareholders' equity, net of tax, and a reduction of 1.6 million potentially dilutive shares.

 2022 Transactions
 During 2022, we repurchased $ 89.1 million in aggregate principal of our 9 % Debentures at a purchase price of $ 121.2 million plus accrued interest. The repurchase of our 9% Debentures resulted in a $ 32.1 million loss on debt extinguishment on our consolidated statement of operations and a reduction of 6.8 million potentially dilutive shares.

 The Federal Home Loan Bank Advance (the "FHLB Advance") was an obligation of MGIC. In 2022, we repaid the outstanding principal balance of the FHLB Advance at a prepayment price of $ 156.3 million, incurring a prepayment fee of $ 1.3 million.

 In July 2022, we redeemed the outstanding principal balance of the 5.75 % Senior Notes ("5.75% Notes") through a make-whole price of $ 248.4 million plus accrued interest. The excess of the make-whole price over the carrying value, plus the write-off of unamortized issuance costs on the par value, resulted in a $ 6.8 million loss on debt extinguishment. The make-whole amount was calculated as the sum of the present values of the remaining scheduled payments of principal and interest discounted at the treasury rate defined in the notes plus 50 basis points and accrued interest. The 5.75% Notes were an obligation of our holding company.

 5.25 % Notes
 Interest on the 5.25 % Notes is payable semi-annually on February 15 and August 15.

 Until August 15, 2025, we may redeem the notes at 101.313 % of principal; on or after August 15, 2025, we may redeem the notes at 100 % of principal; in each case, plus accrued and unpaid interest.

 The 5.25 % Notes have covenants and events of default, which are customary for securities of this nature, and further provide that the trustee or holders of at least 25 % in aggregate principal amount of the outstanding 5.25 % Notes may declare them immediately due and payable upon the occurrence of certain events of default after the expiration of the applicable grace period. In addition, in the case of an event of default arising from certain events of bankruptcy, insolvency or reorganization relating to the Company or any of its significant subsidiaries, the 5.25 % Notes will become due and payable immediately. This description is not intended to be complete in all respects and is qualified in its entirety by the terms of the 5.25 % Notes, including their covenants and events of default. We were in compliance with all covenants as of December 31, 2024.

 INTEREST PAYMENTS
 Interest payments were $ 34.1 million during 2024, $ 35.1 million during 2023 and $ 53.7 million during 2022.

 MGIC Investment Corporation 2024 Form 10-K | 102

 Note 8. Loss Reserves
 As described in Note 3 – "Summary of Significant Accounting Policies – Loss Reserves," we establish case reserves and loss adjustment expenses ("LAE") reserves on delinquent loans that were reported to us as two or more payments past due and have not become current or resulted in a claim payment. Such loans are referred to as being in our delinquency inventory. Case reserves are established by estimating the number of loans in our delinquency inventory that will result in a claim payment, which is referred to as the claim rate, and further estimating the amount of the claim payment, which is referred to as claim severity.

 IBNR reserves are established for estimated losses from delinquencies we estimate have occurred prior to the close of an accounting period, but have not yet been reported to us. IBNR reserves are also established using estimated claim rates and claim severities.

 Estimation of losses is inherently judgmental. The conditions that affect the claim rate and claim severity include the current and future state of the domestic economy, including unemployment and the current and future strength of local housing markets; exposure on insured loans; the amount of time between delinquency and claim filing (all else being equal, the longer the period between delinquency and claim filing, the greater the severity); and curtailments and rescissions. The actual amount of the claim payments may be substantially different than our loss reserve estimates. Our estimates could be adversely affected by several factors, including a deterioration of regional or national economic conditions, including unemployment, leading to a reduction in borrowers' income and thus their ability to make mortgage payments, the impact of past and future government initiatives and actions taken by the GSEs (including mortgage forbearance programs and foreclosure moratoriums), and a drop in housing values which may affect borrower willingness to continue to make mortgage payments when the value of the home is below the mortgage balance. Loss reserves in future periods will also be dependent on the number of loans reported to us as delinquent.

 Changes to our estimates could result in a material impact to our consolidated statements of operations and financial position, even in a stable economic environment. Given the uncertainty of the macroeconomic environment, including the effectiveness of loss mitigation efforts, changes in home prices, and level of employment, our loss reserve estimates may continue to be impacted.

 In considering the potential sensitivity of the factors underlying our estimate of loss reserves, it is possible that even a relatively small change in our estimated claim rate or claim severity could have a material impact on loss reserves and, correspondingly, on our consolidated statements of operations even in a stable economic environment. For example, as of December 31, 2024, assuming all other factors remain constant, a $1,000 increase/decrease in the average severity reserve factor would change the loss reserve amount by approximately +/- $ 7 million. A one percentage point increase/decrease in the average claim rate reserve factor would change the loss reserve amount by approximately +/- $ 18 million.

 The "Losses incurred" section of table 8.1 below shows losses incurred on delinquencies that occurred in the current year and in prior years. The amount of losses incurred relating to delinquencies that occurred in the current year represents the estimated amount to be ultimately paid on such delinquencies. The amount of losses incurred relating to delinquencies that occurred in prior years represents the difference between the actual claim rate and claim severity associated with those delinquencies resolved in the current year compared to the estimated claim rate and claim severity at the prior year-end, as well as a re-estimation of amounts to be ultimately paid on delinquencies continuing from the end of the prior year. This re-estimation of the claim rate and claim severity is the result of our review of current trends in the delinquency inventory, such as percentages of delinquencies that have resulted in a claim, the amount of the claims relative to the average loan exposure, changes in the relative level of delinquencies by geography and changes in average loan exposure.

 MGIC Investment Corporation 2024 Form 10-K | 103

 The "Losses paid" section of table 8.1 below shows the amount of losses paid on delinquencies received in the current year and losses paid on delinquencies that occurred in prior years.

 (1)A positive number for prior year loss development indicates a deficiency of prior year reserves. A negative number for prior year loss development indicates a redundancy of prior year loss reserves. See the following table for more information about prior year loss development.
 (2)In a reinsurance termination, amounts for any incurred but unpaid losses are due to us from the reinsurers. As a result, the amount due from the reinsurers is reclassified from reinsurance recoverable on loss reserves to reinsurance recoverable on paid losses, resulting in no impact to losses incurred. (See Note 9 - "Reinsurance")

 The increase in the current year losses incurred for the year ended December 31, 2024 as compared to the year ended December 31, 2023 is primarily due to an increase in estimated severity on current year delinquencies and an increase in new delinquencies reported, offset by a decrease in the ultimate claim rate on new delinquencies received as of December 31, 2024.

 The favorable loss development on previously received delinquencies for the year ended December 31, 2024 and December 31, 2023 primarily resulted from a decrease in the expected claim rate on previously received delinquencies. Home price appreciation in recent years has allowed some borrowers to cure their delinquencies through the sale of their property.

 The prior year loss reserve development for the past three years is reflected in table 8.2 below.

 PREMIUM REFUNDS
 Our estimate of premiums to be refunded on expected claim payments is accrued for separately in "Other liabilities" on our consolidated balance sheets and was $ 12.5 million and $ 21.1 million at December 31, 2024 and 2023, respectively.

 Note 9. Reinsurance
 Our consolidated financial statements reflect the effects of assumed and ceded reinsurance transactions. Assumed reinsurance refers to the acceptance of certain insurance risks that other insurance companies have underwritten. Ceded reinsurance involves transferring certain insurance risks we have underwritten to other insurance companies who agree to share these risks. The purpose of ceded reinsurance is to protect us, at a cost, against losses arising from our mortgage guaranty policies covered by the agreement and to manage our capital requirements under PMIERs. Reinsurance is currently placed on a quota share and excess of loss basis.

 Table 9.1 below shows the effect of all reinsurance agreements on premiums earned and losses incurred as reflected in the consolidated statements of operations.

 QUOTA SHARE REINSURANCE
 We have entered into QSR transactions with panels of third-party reinsurers to cede a fixed percentage of premiums earned and received and losses incurred on insurance covered by the transactions. We receive the benefit of a ceding commission equal to 20 % of premiums ceded before profit commission. We also receive the benefit of a profit commission through a reduction of premiums we cede. The profit commission varies inversely with the level of losses on a "dollar for dollar" basis and can be eliminated at annual loss ratios higher than we have experienced on our QSR transactions. Ceded losses incurred are impacted by the delinquencies covered by our QSR Transactions, our estimates of payments that will be ultimately made on those delinquencies, and claim payments covered by our QSR Transactions.

 Each of our QSR transactions typically have annual loss ratio caps of 300 % and lifetime loss ratios of 200 %.

 (1)We will receive a profit commission provided the annual loss ratio on policies covered under the transaction remains below this ratio.
 (2)Effective December 31, 2024, we agreed to amended terms with certain participants on our 2020 QSR and 2021 QSR Transaction covering policy year 2021 reducing the quota share cede rate to 14.8 %. Under the amended terms we will generally receive an annual profit commission provided the annual loss ratio on loans covered under the transaction remain below 69 %.
 (3)Effective December 31, 2024, we agreed to amended terms with certain participants on our 2021 QSR and 2022 QSR Transaction covering policy year 2021 reducing the quota share cede rate to 11.1 %. Under the amended terms we will generally receive an annual profit commission provided the annual loss ratio on loans covered under the transaction remain below 69 %.

 We executed a 40 % QSR transaction with a group of unaffiliated reinsurers covering most of our new insurance written in 2025 and 2026. Generally, we will receive an annual profit commission provided the annual loss ratio on the loans covered under the transaction remains below 63.0 % and 62.0 % on 2025 and 2026 new insurance written, respectively.

 We can elect to terminate the QSR Transactions under specified scenarios without penalty upon prior written notice, including if we will receive less than 90 % ( 80 % for the Credit Union QSR Transaction) of the full credit amount under the PMIERs, full financial statement credit or full credit under applicable regulatory capital requirements for the risk ceded in any required calculation period.

 Table 9.3 provides additional detail regarding optional termination dates and optional reductions to our quota share percentage which can, in each case, be elected by us for a fee. Under the optional reduction to the quota share percentage, we may reduce our quota share percentage from the original percentage shown in table 9.2 to the percentage shown in 9.3.

 (1) We can elect early termination of the QSR transaction beginning on this date, and bi-annually thereafter.
 (2) We can elect to reduce the quota share percentage beginning on this date, and bi-annually thereafter.
 (3) Terms of the agreement were amended effective December 31, 2024.

 We incurred an early termination fee of $ 1.0 million for our 2021 QSR Transaction effective December 31, 2024 for reinsurers who did not participate in the amended agreement. We incurred an early termination fee of $ 5.1 million for our 2020 QSR Transaction effective December 31, 2023, and $ 2.2 million for the termination of our 2019 QSR Transaction effective December 31, 2022. We also terminated our 2015 QSR Transaction effective December 31, 2022. The reinsurance recoverable on paid losses due from reinsurers for loss and LAE reserves incurred at the time of termination includes $ 2.7 million as of December 31, 2024 for reinsurers who chose not to participate in the 2021 QSR Transaction amendment, $ 9.4 million as December 31, 2023 from reinsurers participating in the 2020 QSR Transaction and $ 17.7 million as of December 31, 2022 from reinsurers participating in the 2015 and 2019 QSR Transactions.

 MGIC Investment Corporation 2024 Form 10-K | 106

 Under the terms of our QSR Transactions, ceded premiums, ceding commissions, profit commission, and ceded loss paid and LAE paid are settled net on a quarterly basis. The ceded premiums due after deducting the related ceding commission and profit commission is reported within "Other liabilities" on the consolidated balance sheets.
 The reinsurance recoverable on loss reserves related to our QSR Transactions was $ 47.3 million as of December 31, 2024 and $ 33.3 million as of December 31, 2023. The reinsurance recoverable balance is secured by funds on deposit from the reinsurers (which does not include letters of credit), the minimum amount of which is based on the greater of 1) a reinsurer's funding requirements under PMIERs or 2) ceded reserves and unpaid losses. Each of the reinsurers under our quota share reinsurance agreements described above has an insurer financial strength rating of A- or better (or a comparable rating) by Standard and Poor's Rating Services, A.M. Best, Moody's, or a combination of the three. An allowance for credit losses was not required as of December 31, 2024 or December 31, 2023.
 EXCESS OF LOSS REINSURANCE

 We have XOL Transactions with a panel of unaffiliated reinsurers executed through the traditional reinsurance market ("Traditional XOL Transactions") and with unaffiliated special purpose insurers ("Home Re Transactions").

 For the policies covered under our Traditional XOL Transactions, we retain the first layer of the aggregate losses paid, and the reinsurers will then provide second layer coverage up to the outstanding reinsurance coverage amount. We retain losses paid in excess of the outstanding reinsurance coverage amount. The reinsurance coverage is subject to adjustment based on the risk characteristics of the covered loans until the initial excess of loss reinsurance coverage layer has been finalized.

 We can elect to terminate our Traditional XOL Transactions under specified scenarios without penalty upon prior written notice, including if we will receive less than the full credit amount under the PMIERs, full financial statement credit or full credit under applicable regulatory capital requirements for the risk ceded in any required calculation period. The reinsurance premiums ceded under the Traditional XOL Transactions are based off the remaining reinsurance coverage levels. The reinsured coverage levels are secured by funds on deposit from reinsurers (which does not include letters of credit), the minimum amount of which is based on the greater of 1) a reinsurer's funding requirements under PMIERs or 2) ceded reserves and unpaid losses. Each of the reinsurers under our Traditional XOL Transactions has an insurer financial strength rating of A- or better (or a comparable rating) by Standard and Poor's Rating Services, A.M. Best, Moody's, or a combination of the three.

 The Home Re Transactions are executed with unaffiliated special purpose insurers ("Home Re Entities"). For the reinsurance coverage periods, we retain the first layer of the respective aggregate losses paid, and a Home Re Entity will then provide second layer coverage up to the outstanding reinsurance coverage amount. We retain losses paid in excess of the outstanding reinsurance coverage amount. Subject to certain conditions, the reinsurance coverage decreases as the underlying covered mortgages amortize or are repaid, or mortgage insurance losses are paid.

 The Home Re Entities financed the coverages by issuing mortgage insurance-linked notes ("ILNs") to unaffiliated investors in an aggregate amount equal to the initial reinsurance coverage amounts. Each ILN is non-recourse to any assets of MGIC or affiliates. The proceeds of the ILNs, which were deposited into reinsurance trusts for the benefit of MGIC, will be the source of reinsurance claim payments to MGIC and principal repayments on the ILNs.

 Payment of principal on the related insurance-linked notes will be suspended and the reinsurance coverage available to MGIC under the transactions will not be reduced by such principal payments until a target level of credit enhancement is obtained or if certain thresholds or "Trigger Events" are reached, as defined in the related insurance-linked notes transaction agreement. As of December 31, 2024, there were no "Trigger Events".

 In 2024, we exercised our option to terminate the reinsurance agreement with Home Re 2020-1, Ltd. and Home Re 2018-1, Ltd. We also terminated our reinsurance agreement with Home Re 2019-1, Ltd. In connection with the terminations, the insurance linked notes issued by Home Re 2020-1 Ltd., Home Re 2019-1 Ltd, and Home Re 2018-1, Ltd. were redeemed in full.

 (1)The initial and remaining excess of loss reinsurance coverage is reduced by the applicable funding percentage.
 (2)The funding percentage represents the aggregate outstanding note balances divided by the aggregate ending coverage amounts.
 (3)The funding percentage on the 2021-2 was reduced from 100 % after a tender offer was conducted in the fourth quarter of 2023.

 The reinsurance premiums ceded to each Home Re Entity are composed of coverage, initial expense and supplemental premiums. The coverage premiums are generally calculated as the difference between the amount of interest payable by the Home Re Entity on the remaining reinsurance coverage levels, and the investment income collected on the collateral assets held in reinsurance trust account and used to collateralize the Home Re Entity's reinsurance obligation to MGIC. The amount of monthly reinsurance coverage premium ceded will fluctuate due to changes in the reference rate and changes in money market rates that affect investment income collected on the assets in the reinsurance trust. As a result, we concluded that each Home Re Transaction contains an embedded derivative that is accounted for separately as a freestanding derivative. The fair values of the derivatives at December 31, 2024 and December 31, 2023, were not material to our consolidated balance sheet, and the change in fair values during the years ended December 31, 2024, December 31, 2023 and December 31, 2022 were not material to our consolidated statements of operations. (see Note 5 - "Investments" and Note 6 - "Fair Value Measurements").

 MGIC Investment Corporation 2024 Form 10-K | 108

 At the time the Home Re Transactions were entered into, we concluded that each Home Re Entity is a variable interest entity ("VIE"). A VIE is a legal entity that does not have sufficient equity at risk to finance its activities without additional subordinated financial support or is structured such that equity investors lack the ability to make sufficient decisions relating to the entity's operations through voting rights or do not substantively participate in gains and losses of the entity. Given that MGIC (1) does not have the unilateral power to direct the activities that most significantly affect each Home Re Entity's economic performance and (2) does not have the obligation, outside the terms of the reinsurance agreement, to absorb losses or the right to receive benefits of each Home Re Entity that could be significant to the Home Re Entity, consolidation of the Home Re Entities is not required.

 We are required to disclose our maximum exposure to loss, which we consider to be an amount that we could be required to record in our statements of operations, as a result of our involvement with the VIEs under our Home Re Transactions. As of December 31, 2024, December 31, 2023 and December 31, 2022, we did not have material exposure to the VIEs as we have no investment in the VIEs and had no reinsurance claim payments due from the VIEs under our reinsurance transactions. We are unable to determine the timing or extent of claims from losses that are ceded under the reinsurance transactions. The VIE assets are deposited in reinsurance trusts for the benefit of MGIC that will be the source of reinsurance claim payments to MGIC. The purpose of the reinsurance trusts is to provide security to MGIC for the obligations of the VIEs under the reinsurance transactions. The trustee of the reinsurance trusts, a recognized provider of corporate trust services, has established segregated accounts within the reinsurance trusts for the benefit of MGIC, pursuant to the trust agreements. The trust agreements are governed by, and construed in accordance with, the laws of the State of New York. If the trustee of the reinsurance trusts failed to distribute claim payments to us as provided in the reinsurance trusts, we would incur a loss related to our losses ceded under the reinsurance transactions and deemed unrecoverable. We are also unable to determine the impact such possible failure by the trustee to perform pursuant to the reinsurance trust agreements may have on our consolidated financial statements. As a result, we are unable to quantify our maximum exposure to loss related to our involvement with the VIEs. MGIC has certain termination rights under the reinsurance transactions should its claims not be paid. We consider our exposure to loss from our reinsurance transactions with the VIEs to be remote.

 The reinsurance trust agreements provide that the trust assets may generally only be invested in certain money market funds that (1) invest at least 99.5 % of their total assets in cash or direct U.S. federal government obligations, such as U.S. Treasury bills, as well as other short-term securities backed by the full faith and credit of the U.S. federal government or issued by an agency of the U.S. federal government, (2) have a principal stability fund rating of "AAAm" by S&P or a money market fund rating of "Aaamf" by Moody's as of the Closing Date and thereafter maintain any rating with either S&P or Moody's, and (3) are permitted investments under the applicable credit for reinsurance laws and applicable PMIERs credit for reinsurance requirements.

 The total calculated PMIERs credit for risk ceded under our XOL Transactions is generally based on the PMIERs requirement of the covered policies and the attachment and detachment points of the coverage, all of which fluctuate over time. (see Note 1 - "Nature of Business" and Note 2 - "Basis of Presentation").

 Note 11. Benefit Plans
 We have a non-contributory defined benefit pension plan, as well as a supplemental executive retirement plan, that covered eligible employees through December 31, 2022. Effective January 1, 2023, these plans were frozen (no future benefits will be accrued for participants due to employment and no new participants will be added). Participants in these plans were fully vested in their benefits as of December 31, 2022. We also offer benefits for retired domestic employees and their eligible spouses and dependents under a postretirement benefit plan. Participation in this plan is limited to eligible employees that participated in the defined benefit pension plan. The following tables 11.1, 11.2, and 11.3 provide the components of aggregate annual net periodic benefit cost for each of the years ended December 31, 2024, 2023, and 2022 and changes in the benefit obligation and the funded status of the pension, supplemental executive retirement and other postretirement benefit plans as recognized in the consolidated balance sheets as of December 31, 2024 and 2023.

 The amortization of gains and losses resulting from differences in actual experience from expected experience, or changes in assumptions including discount rates, is included as a component of Net Periodic Benefit Cost (Benefit) for the year. The gain or loss in excess of a 10 % corridor is amortized by the average remaining life expectancy for the pension and supplemental executive retirement plans and by the average remaining service period of participating employees expected to receive benefits under the other postretirement benefits plan.

 (1)Represents lump sum payments from our pension plan to eligible participants, who were former employees with vested benefits.

 The change in the net actuarial losses (gains) on the benefit obligation from 2023 to 2024 is primarily due to changes in the discount rate used to calculate the benefit obligation. When the discount rate increases, the impact on the benefit obligation is a decrease, resulting in an actuarial gain. When the discount rate decreases, the impact on the benefit obligation is an increase, resulting in an actuarial loss. The discount rate increased to 5.70 % at December 31, 2024 from 5.20 % at December 31, 2023, compared to a decrease to 5.20 % at December 31, 2023 from 5.60 % at December 31, 2022. See Table 11.7 for the actuarial assumptions used to calculate the benefit obligations of our plans for 2024 and 2023.

 Tables 11.5 and 11.6 shows the changes in the fair value of the net assets available for plan benefits and changes in other comprehensive income (loss) for the years ended December 31, 2024 and 2023.

 In selecting a discount rate, we performed a hypothetical cash flow bond matching exercise, matching our expected pension plan and postretirement medical plan cash flows, respectively, against a selected portfolio of high quality corporate bonds. The modeling was performed using a bond portfolio of noncallable bonds with at least $ 50 million outstanding. The average yield of these hypothetical bond portfolios was used as the benchmark for determining the discount rate. In selecting the expected long-term rate of return on assets, we considered the average rate of earnings expected on the classes of funds invested or to be invested to provide for the benefits of these plans. This included considering the trusts' targeted asset allocation for the year and the expected returns likely to be earned over the next 20 years.

 The year-end asset allocations of the plans are shown in table 11.8 below.

 Fair value is disclosed using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value as described in Note 6 - "Fair Value Measurements" and Note 3 - "Significant Accounting Policies".

 The following describes the valuation methodologies used for pension plan and other postretirement benefits plan assets at fair value.
 • Domestic and International Mutual Funds: Securities are priced at the net asset value ("NAV"), which is the closing price published by the mutual fund on the reporting date. These financial assets are categorized as Level 1 in the fair value hierarchy.
 • U.S. Government Securities: See Note 6 - "Fair Value Measurements" for a discussion of the valuation methodologies for U.S. Treasury Securities and Obligations of U.S. Government Corporations and Agencies.
 • Corporate Debt Securities: See Note 6 - "Fair Value Measurements" for a discussion of the valuation methodologies for Corporate Debt.
 • Non-Government Foreign Debt Securities: These financial assets are represented by corporate debt securities issued by entities domiciled outside of the United States. See Note 6 - "Fair Value Measurements" for a discussion of the valuation methodologies for Corporate Debt.
 • Municipal Bonds: See Note 6 - "Fair Value Measurements" for a discussion of the valuation methodologies for Obligations of U.S. States & Political Subdivisions.

 MGIC Investment Corporation 2024 Form 10-K | 113

 • Pooled Equity Accounts: Pooled Equity Account assets are represented by the units held by the plan. The redemption value is determined based on the NAV of the underlying units. The NAV is derived from the aggregate fair value of the underlying investments less any liabilities as of the reporting date. These financial assets are categorized as Level 2 in the fair value hierarchy.

 The pension plan assets and related accrued investment income at fair value, by hierarchy level, as of December 31, 2024 and 2023, are shown in tables 11.9a and 11.9b below. There were no securities valued using Level 3 inputs.

 The pension plan has implemented a strategy to reduce risk through the use of a targeted funded ratio. The liability driven component is key to the asset allocation. The liability driven component seeks to align the duration of the fixed income asset allocation with the expected duration of the plan liabilities or benefit payments. Overall asset allocation is dynamic and specifies target allocation weights and ranges based on the funded status.

 An improvement in funded status results in the de-risking of the portfolio, allocating more funds to fixed income and less to equity. A decline in funded status would result in a higher allocation to equity. The maximum equity allocation is 40 %.

 The equity investments use combinations of mutual funds, ETFs, and pooled equity account structures focused on the following strategies:

 Strategy
 Objective
 Investment types

 Return seeking growth
 Funded ratio improvement over the long term

 Global quality growth

 Global low volatility

 Return seeking bridge
 Downside protection in the event of a declining equity market

 Enduring asset

 Durable company

 The fixed income objective is to preserve capital and to provide monthly cash flows for the payment of plan liabilities. Fixed income investments can include government, government agency, corporate, mortgage-backed, asset-backed, and municipal securities, and other classes of bonds. The duration of the fixed income portfolio has an objective of being within one year of the duration of the accumulated benefit obligation. The fixed income investments have an objective of a weighted average credit of A3/A-/A- by Moody's, S&P, and Fitch, respectively.

 Our postretirement plan portfolio is designed to achieve the following objectives over each market cycle and for at least 5 years:
 Total return should exceed growth in the Consumer Price Index by 5.75 % annually
 Achieve competitive investment results

 The primary focus in developing asset allocation ranges for the portfolio is the assessment of the portfolio's investment objectives and the level of risk that is acceptable to obtain those objectives. To achieve these objectives the minimum and maximum allocation ranges for fixed income securities and equity securities are:

 Minimum
 Maximum

 Equities (long only)
 %
 %

 Real estate
 %
 %

 Commodities
 %
 %

 Fixed income/Cash
 %
 %

 Given the long term nature of this portfolio and the lack of any immediate need for significant cash flow, it is anticipated that the equity investments will consist of growth stocks and will typically be at the higher end of the allocation ranges above.

 Investment in international mutual funds is limited to a maximum of 30 % of the equity range. The allocation as of December 31, 2024 included 2 % that was primarily invested in equity securities of emerging market countries and another 15 % was invested in securities of companies primarily based in Europe and the Pacific Basin.

 For the year ended December 31, 2024, we contributed $ 23.3 million to the pension and supplemental executive retirement plans. We do not expect to make a contribution to the pension plan in 2025 and distributions from the supplemental executive retirement plan will be funded as incurred. We did not make a contribution to the other postretirement benefits plan in 2024 and we do not expect to make a contribution in 2025.

 Expected future benefit payments from the plans are shown in Table 11.11 below.

 Note 13. Shareholders' Equity
 TREASURY STOCK
 Prior to November 15, 2024, shares we repurchased were held in treasury stock unless they were reissued under the discretion of our Board of Directors. As of November 15, 2024, we retired all shares of our treasury stock, which resulted in an adjustment to retained earnings equal to the cumulative amount of repurchase price paid in excess of par value for treasury stock held as of that date. Subsequent to the retirement of the treasury stock, all shares of our common stock that we repurchase are immediately retired. Going forward, the amount of repurchase price paid in excess of par value for repurchased shares will be recorded as an adjustment to retained earnings.

 SHARE REPURCHASE PROGRAMS
 Repurchases may be made from time to time on the open market (including through 10b5-1 plans) or through privately negotiated transactions. In 2024, we repurchased approximately 25.3 million shares of our common stock for $ 566.6 million, which included commissions. We may repurchase up to an additional $ 457.2 million of our common stock through December 31, 2026 under a share repurchase program approved by our Board of Directors in 2024. In the year to date period ended February 21, 2025 we repurchased approximately 5.8 million shares for $ 142.3 million, which included commissions.

 In 2023, we repurchased approximately 21.7 million shares for $ 340.6 million, which included commissions.

 CASH DIVIDENDS
 In the first and second quarters of 2024, we paid quarterly cash dividends of $ 0.115 per share to shareholders which totaled $ 63.3 million. In the third and fourth quarters of 2024, we paid quarterly cash dividends of $ 0.13 per share which totaled $ 67.8 million. On January 28, 2025, the Board of Directors declared a quarterly cash dividend to holders of the company's common stock of $ 0.13 per share payable on March 5, 2025, to shareholders of record at the close of business on February 18, 2025.

 Note 14. Statutory Information
 STATUTORY ACCOUNTING PRINCIPLES
 The statutory financial statements of our insurance companies are presented on the basis of accounting principles prescribed, or practices permitted, by the Office of the Commissioner of Insurance of the State of Wisconsin (the "OCI"), which has adopted the National Association of Insurance Commissioners ("NAIC") Statements of Statutory Accounting Principles ("SSAP") as the basis of its statutory accounting principles, except as described below. In converting from statutory to GAAP, typical adjustments include deferral of policy acquisition costs, the inclusion of net unrealized holding gains or losses in shareholders' equity relating to fixed income securities, and the inclusion of statutory non-admitted assets.

 In addition to the typical adjustments from statutory to GAAP, mortgage insurance companies are required to maintain contingency loss reserves equal to 50% of premiums earned under SSAP and principles prescribed by the OCI. Such amounts cannot be withdrawn for a period of ten years except as permitted by insurance regulations. With regulatory approval, a mortgage guaranty insurance company may make early withdrawals from the contingency reserve when incurred losses exceed 35% of premiums earned in a calendar year. Changes in contingency loss reserves impact the statutory statement of operations. Contingency loss reserves are not reflected as liabilities under GAAP and changes in contingency loss reserves do not impact the GAAP consolidated statements of operations.

 As a mortgage guaranty insurer, we are eligible for a tax deduction, subject to certain limitations, under Section 832(e) of the IRC for amounts required by state law or regulation to be set aside in statutory contingency reserves. The deduction is allowed only to the extent that we purchase tax and loss bonds ("T&L Bonds") in an amount equal to the tax benefit derived from deducting any portion of our statutory contingency reserves. Under statutory accounting practices, purchases of T&L Bonds are accounted for as investments. Under GAAP, purchases of T&L Bonds are accounted for as a payment of current taxes.

 STATUTORY CAPITAL REQUIREMENTS
 The insurance laws of 16 jurisdictions, including Wisconsin, our domiciliary state, require a mortgage insurer to maintain a minimum amount of statutory capital relative to the RIF (or a similar measure) in order for the mortgage insurer to continue to write new business. We refer to these requirements as the "State Capital Requirements" and, together with the GSE Financial Requirements, the "Financial Requirements." While they vary among jurisdictions, the most common State Capital Requirements allow for a maximum risk-to-capital ratio of 25 to 1. A risk-to-capital ratio will increase if (i) the percentage decrease in capital exceeds the percentage decrease in insured risk, or (ii) the percentage increase in capital is less than the percentage increase in insured risk. Wisconsin does not regulate capital by using a risk-to-capital measure but instead requires a minimum policyholder position ("MPP"). MGIC's "policyholder position" includes its net worth or surplus, and its contingency loss reserve. Our policyholders position was above the required MPP and our risk-to-capital ratio was below the maximum allowed by jurisdictions with State Capital Requirements at December 31, 2024.

 In 2023, the NAIC adopted a revised Mortgage Guaranty Insurance Model Act. The updated Model Act includes requirements relating to, among other things: (i) capital and minimum capital requirements, and contingency reserves; (ii) restrictions on mortgage insurers' investments in notes secured by mortgages; (iii) prudent underwriting standards and formal underwriting guidelines; (iv) the

 MGIC Investment Corporation 2024 Form 10-K | 117

 establishment of formal, internal "Mortgage Guaranty Quality Control Programs" with respect to in-force business; and (v) reinsurance and prohibitions on captive reinsurance arrangements. It is uncertain when the revised Model Act will be adopted in any jurisdiction. It is unknown whether any changes will be made by state legislatures prior to adoption, and the effect changes, if any, will have on the mortgage guaranty insurance market generally, or on our business. Wisconsin has begun the process to replace current mortgage insurance regulations with the Model Act, though it is expected that some changes will be made before formal adoption.

 DIVIDEND RESTRICTIONS
 MGIC is subject to statutory regulations as to payment of dividends. The maximum amount of dividends that MGIC may pay in any twelve-month period without regulatory approval by the OCI is the lesser of adjusted statutory net income or 10 % of statutory policyholders' surplus as of the preceding calendar year end. Adjusted statutory net income is defined for this purpose to be the greater of statutory net income, net of realized investment gains, for the calendar year preceding the date of the dividend or statutory net income, net of realized investment gains, for the three calendar years preceding the date of the dividend less dividends paid within the first two of the preceding three calendar years. The maximum dividend that could be paid, without regulatory approval, is reduced by dividends paid in the twelve months preceding the dividend payment date. Before making any dividend payments, we notify the OCI to ensure it does not object. In 2024, MGIC paid $ 750 million in dividends to the holding company.

 STATUTORY FINANCIAL INFORMATION
 The OCI recognizes only statutory accounting principles prescribed, or practices permitted, by the State of Wisconsin for determining and reporting the financial condition and results of operations of an insurance company. The OCI has adopted certain prescribed accounting practices that differ from those found in other states. Specifically, Wisconsin domiciled companies record changes in the contingency loss reserves through the income statement as a change in underwriting deduction. As a result, in periods in which MGIC is increasing contingency loss reserves, statutory net income is reduced.

 The statutory net income, policyholders' surplus, and contingency reserve liability of our insurance subsidiaries, including MGIC, are shown in table 14.1.

 The increase in statutory net income for the year ended December 31, 2024 was primarily driven by the decrease in the contingency reserve in 2024 as compared to an increase in the contingency reserve for the year ended December 31, 2023. The increase in statutory policyholders' surplus for the year ended December 31, 2024 is primarily due to statutory net income, offset by dividend payments to MGIC Investment Corporation ("the holding company") (discussed below).

 For the years ended December 31, 2024, 2023, and 2022 there were no contributions made to MGIC or distributions from other insurance subsidiaries to us. Dividends paid by MGIC are shown in table 14.2 below.

 Note 15. Share-based Compensation Plans
 We have certain share-based compensation plans. Under the fair value method, compensation cost is measured at the grant date based on the fair value of the award and is recognized over the service period which generally corresponds to the vesting period. Awards under our plans generally vest over periods ranging from one to three years, although awards to our non-employee directors vest immediately.

 We have an omnibus incentive plan that was adopted on April 23, 2020. When the 2020 plan was adopted, no further awards could be made under our previous 2015 plan. The purpose of the 2020 plan is to motivate and incentivize performance by, and to retain the services of, key employees and non-employee directors through receipt of equity-based and other incentive awards under the plan. Awards issued under the plan that are subsequently forfeited will not count against the limit on the maximum number of shares that may be issued under the plan. The 2020 plan provides for the award of stock options, stock appreciation rights, restricted stock and restricted stock units, as well as cash incentive awards. No awards may be granted after April 23, 2030 under the 2020 plan. The vesting provisions of options, restricted stock and restricted stock units are determined at the time of grant. At December 31, 2024, 3.6 million shares were available for future grant under the 2020 plan.

 The compensation cost that has been charged against income for share-based plans was $ 31.2 million, $ 31.5 million, and $ 24.7 million for the years ended December 31, 2024, 2023 and 2022, respectively. The related income tax benefit recognized for share-based plans was $ 2.4 million, $ 2.9 million, and $ 2.1 million for the years ended December 31, 2024, 2023, and 2022, respectively. Table 15.1 summarizes restricted stock or restricted stock unit (collectively called "restricted stock") activity during 2024.

 (2) Amount represents the difference between the number of shares vested at settlement with performance conditions and the number of target shares at the grant date in 2021.

 At December 31, 2024, the 2.8 million shares of restricted stock outstanding consisted of 2.1 million shares that are subject to performance conditions ("performance shares"), 0.5 million shares that are subject only to service conditions ("time vested shares"), and 0.2 million shares related to non-employee director shares. The weighted-average grant date fair value of restricted stock granted during 2023 and 2022 was $ 14.17 and $ 15.45, respectively. The fair value of restricted stock granted is the closing price of the common stock on the New York Stock Exchange on the date of grant or previous trading day if the New York Stock Exchange is closed on the date of grant. The total fair value of restricted stock vested during 2024, 2023 and 2022 was $ 43.2 million, $ 17.3 million, and $ 23.3 million, respectively.

 As of December 31, 2024, the total unrecognized compensation cost for all of our outstanding share-based awards was $ 23.1 million. A portion of the unrecognized costs associated with the outstanding shares may or may not be recognized in future periods, depending upon whether or not the performance and/or service conditions are met. The cost associated with the outstanding share-based awards is expected to be recognized over a weighted-average period of 1.6 years.

 Note 17. Litigation and Contingencies
 We operate in a highly regulated industry that is subject to the risk of litigation and regulatory proceedings, including related to our claims paying practices. From time to time, we are involved in disputes and legal proceedings in the ordinary course of business. In our opinion, based on the facts known at this time, the ultimate resolution of these ordinary course disputes and legal proceedings will not have a material adverse effect on our financial position or results of operations.
 Under ASC 450-20, until a loss associated with settlement discussions or legal proceedings becomes probable and can be reasonably estimated we do not accrue an estimated loss. When we determine that a loss is probable and can be reasonably estimated, we record our best estimate of our probable loss.

 Note 18. Segment Reporting
 We operate as a single reportable segment, which is defined as Mortgage Insurance. This segment generates revenue through mortgage insurance and reinsurance provided under the GSEs credit risk transfer programs. The results of our Mortgage Insurance segment are reported within our financial statements as the consolidated financial results for MGIC Investment Corporation and Subsidiaries. The accounting policies of the Mortgage Insurance segment are the same as those described in Note 3. Significant Accounting Policies.

 The Senior Management Oversight Committee ("SMOC"), acts as the Company's chief operating decision maker ("CODM"). The CODM uses consolidated net income (loss) as the primary GAAP measure to evaluate actual financial performance versus planned financial performance and to allocate resources. The measure of segment assets is reported on the balance sheet as total consolidated assets.

 The table below presents a disaggregation of significant segment expenses as monitored by our CODM:

 Report of Independent Registered Public Accounting Firm

 To the Board of Directors and Shareholders of MGIC Investment Corporation

 Opinions on the Financial Statements and Internal Control over Financial Reporting

 We have audited the accompanying consolidated balance sheets of MGIC Investment Corporation and its subsidiaries (the "Company") as of December 31, 2024 and 2023, and the related consolidated statements of operations, of comprehensive income, of shareholders' equity and of cash flows for each of the three years in the period ended December 31, 2024, including the related notes and financial statement schedules listed in the index appearing under Item 15(a)(2) (collectively referred to as the "consolidated financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2024, 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 consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024 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, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

 Basis for Opinions

 The Company's management is responsible for these consolidated 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 Management's Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company's consolidated financial statements and 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 consolidated 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 consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated 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 consolidated 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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) 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 (iii) 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 matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a

 MGIC Investment Corporation 2024 Form 10-K | 121

 whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

 Valuation of Loss Reserves – Primary Case Reserves

 As described in Notes 3 and 8 to the consolidated financial statements, the Company establishes case reserves for estimated insurance losses when notices of delinquency on insured mortgage loans are received. As of December 31, 2024, the Company's recorded loss reserves were $463 million. A significant portion of total loss reserves relate to primary case reserves established for the Company's primary insurance business. Case reserves are established by estimating the number of loans in the delinquency inventory that will result in a claim payment, which is referred to as the claim rate, and further estimating the amount of the claim payment, which is referred to as claim severity. The Company's case reserve estimates are primarily established based upon historical experience, including rescissions of policies, curtailments of claims, and loan modification activity. The conditions that affect the claim rate and claim severity include the current and future state of the domestic economy, including unemployment and the current and future strength of local housing markets; exposure on insured loans; the amount of time between delinquency and claim filing; and curtailments and rescissions.

 The principal considerations for our determination that performing procedures relating to the valuation of loss reserves – primary case reserves is a critical audit matter are (i) the significant judgment by management when developing the estimate of the primary case reserves; (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating the audit evidence relating to the claim rate and claim severity significant assumptions; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.

 Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the valuation of loss reserves, including controls over the development of significant assumptions related to the claim rate and claim severity. These procedures also included, among others, the involvement of professionals with specialized skill and knowledge to assist in developing an independent estimate of the primary case reserves and comparing this independent estimate to management's recorded primary case reserves to evaluate the reasonableness of the recorded primary case reserves. Developing the independent estimate involved testing the completeness and accuracy of data provided by management and independently developing assumptions related to the claim rate and claim severity.

 MANAGEMENT'S CONCLUSION REGARDING THE EFFECTIVENESS OF DISCLOSURE CONTROLS
 Our management, with the participation of our principal executive officer and principal financial officer, has evaluated our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended), as of the end of the period covered by this annual report. Based on such evaluation, our principal executive officer and principal financial officer concluded that such controls and procedures were effective as of the end of such period.

 MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
 Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Exchange Act Rule 13a-15(f) and 15d-15(f)). Our internal control over financial reporting is 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. Because of its inherent limitations, however, 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.

 Our management, with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of our internal control over financial reporting using the framework in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on such evaluation, our management concluded that our internal control over financial reporting was effective as of December 31, 2024.

 PricewaterhouseCoopers LLP, an independent registered public accounting firm, has audited the consolidated financial statements and effectiveness of internal control over financial reporting as of December 31, 2024, as stated in their report which appears herein.

 CHANGES IN INTERNAL CONTROL DURING THE FOURTH QUARTER
 There are no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) and Rule 15d-15(f) under the Exchange Act) that occurred during the quarter ended December 31, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

 Item 9B. Other Information
 During the three months ended December 31, 2024, none of our officers or directors adopted, modified or terminated any contract, instruction or written plan for the purchase or sale of our securities that was intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) or any "non-Rule 10b5-1 trading arrangement."

 SCHEDULE II — CONDENSED FINANCIAL INFORMATION OF REGISTRANT
 PARENT COMPANY ONLY
 SUPPLEMENTARY NOTES

 Note A

 The accompanying Parent Company financial statements should be read in conjunction with the consolidated financial statements and notes to the consolidated financial statements appearing in this annual report.

 Note B

 Our insurance subsidiaries are subject to statutory regulations as to maintenance of policyholders' surplus and payment of dividends. The maximum amount of dividends that the insurance subsidiaries may pay in any twelve-month period without regulatory approval by the OCI is the lesser of adjusted statutory net income or 10 % of statutory policyholders' surplus as of the preceding calendar year end. Adjusted statutory net income is defined for this purpose to be the greater of statutory net income, net of realized investment gains, for the calendar year preceding the date of the dividend or statutory net income, net of realized investment gains, for the three calendar years preceding the date of the dividend less dividends paid within the first two of the preceding three calendar years. The maximum dividend that could be paid is reduced by dividends paid in the twelve months preceding the dividend payment date. Before making any dividend payments in 2025, we will notify the OCI to ensure it does not object.

 The payment of dividends from MGIC is the principal source of cash inflow for MGIC Investment Corporation, our holding company, other than investment income and raising capital in the public markets. The payment of dividends by our insurance subsidiaries is restricted by insurance regulation as discussed above. MGIC paid a total of $ 750 million, $ 600 million and $ 800 million in dividends in cash and fixed income securities to our holding company during 2024, 2023, and 2022, respectively. No contributions were made to our insurance subsidiaries in 2024, 2023, or 2022. In 2024, capital of $ 40 million was returned to our holding company from a non-insurance subsidiary.

 Note C

 The 5.25 % Senior Notes discussed in Note 7 – "Debt" to our consolidated financial statements, are obligations of MGIC Investment Corporation, our holding company, and not of its subsidiaries.
