Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	1. Basis of Presentation American International Group, Inc. is a leading global insurance organization. AIG provides insurance solutions that help businesses and individuals in over 200 countries and jurisdictions protect their assets and manage risks through AIG operations, licenses and authorizations as well as network partners. Unless the context indicates otherwise, the terms “AIG,” “we,” “us,” “our” or "the Company" mean American International Group, Inc. and its consolidated subsidiaries, and the term “AIG Parent” means American International Group, Inc. and not any of its consolidated subsidiaries. The consolidated financial statements include the accounts of AIG Parent, our controlled subsidiaries (generally through a greater than 50 percent ownership of voting rights and voting interests), and variable interest entities (VIEs) of which we are the primary beneficiary. Equity investments in entities that we do not consolidate, including corporate entities in which we have significant influence and partnership and partnership-like entities in which we have more than minor influence over the operating and financial policies, are accounted for under the equity method unless we have elected the fair value option. Prior to the fourth quarter ending December 31, 2022, certain of our foreign property and casualty subsidiaries reported on the basis of a fiscal year ending November 30. The effect on our consolidated financial condition and results of operations of all material events occurring at these subsidiaries from November 30 through December 31 of the periods previously presented in these Consolidated Financial Statements was considered for adjustment and/or disclosure. Effective with the fourth quarter of the year ended December 31, 2022, the foreign property and casualty subsidiaries now report on a calendar year ending December 31. The elimination of a one-month reporting lag of a subsidiary is considered a change in accounting principle. We believe this change in accounting principle is preferable given that it aligns the reporting dates with other consolidated entities, which allows for a timelier and more consistent basis of reporting within our Consolidated Financial Statements. A change in accounting principle requires retrospective application. However, we determined that the effect of not retroactively applying this change was not material to our Consolidated Financial Statements for the current and prior periods. Therefore, we reported the cumulative effect of the change in accounting principle within the Consolidated Statements of Income (Loss) for the year ended December 31, 2022 and did not retrospectively apply the effects of this change to prior periods. The adoption impact was an increase to net income of $100 million for the year ended December 31, 2022. The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP). All material intercompany accounts and transactions have been eliminated. SALES/DISPOSALS OF ASSETS AND BUSINESSES Crop Risk Services On July 3, 2023, AIG closed the sale of Crop Risk Services, Inc. (CRS) to American Financial Group, Inc. (AFG) and in substance, AIG exited the crop business. The gross proceeds, before deducting commissions, were $234 million, resulting in a pre-tax gain of $72 million for the year ended December 31, 2023 . Validus Re On November 1, 2023, AIG completed the sale of Validus Reinsurance, Ltd. (Validus Re), including AlphaCat Managers Ltd. and the Talbot Treaty reinsurance business, to RenaissanceRe Holdings Ltd. (RenaissanceRe) and received cash proceeds of $2.7 billion from RenaissanceRe and 1.3 million shares of RenaissanceRe common stock valued at $290 million as of the closing date, resulting in a pre-tax loss of $78 million for the year ended December 31, 2023 . The results of Validus Re are reported in North America Commercial and International Commercial segments. Additionally, AIG agreed to retain 95 percent of the difference between (i) the reserves with respect to the business as of the closing date of the sale for losses occurring prior to the closing date and (ii) the associated reserve development following the closing date with respect to such losses. Any reserve development will be settled annually, commencing with the calendar year ending December 31, 2024. This arrangement stays in effect until the parties determine to terminate such arrangement (which they will re-evaluate on an annual basis beginning 5 years after the closing date) or until all such liabilities of the acquired reinsurance business have run off. The reserve cover is considered contingent consideration and was recognized at fair value of $130 million when the sale closed. On September 4, 2023, AIG entered into an Adverse Development Cover Excess of Loss Agreement (the ADC Agreement) to hedge the risk of adverse development pertaining to Validus Re’s reserves with Clarendon National Insurance Company, a wholly owned subsidiary of Enstar Group Limited. Under the ADC Agreement, AIG will be reimbursed up to $400 million of adverse development for all policies in force as of December 31, 2022 when paid losses exceed the baseline reserve balance of $3.043 billion. The premium expensed in connection with the ADC Agreement was $80 million. Global Personal Travel Business On December 2, 2024, AIG concluded the sale of its global individual personal travel insurance and assistance business to Zurich Insurance Group (Zurich) for $600 million in cash plus additional earn-out consideration, resulting in a pre-tax gain of $511 million for the year ended December 31, 2024 . The global individual personal travel insurance and assistance business is reported in Global Personal segment. AIG has also agreed to provide transition services to Zurich for 30 months after the transaction date. Additionally, AIG has fronting agreements in place to front 100 percent of all new travel business produced by Zurich; whereby all of the economics of the new travel business will pass to Zurich through the fronting arrangements which is recognized as a component of Net gain (loss) on divestitures and other. OTHER EVENTS On December 14, 2022, AIG announced that its wholly-owned subsidiary, AIG Financial Products Corp. (AIGFP), filed a voluntary petition to reorganize under Chapter 11 of Title 11 of the United States Code in the United States Bankruptcy Court for the District of Delaware and filed a proposed plan of reorganization. The reorganization will not have a material impact on the consolidated balance sheets of AIG or our respective businesses. AIGFP has no material operations or businesses and no employees. In conjunction with the bankruptcy filing, AIGFP and its consolidated subsidiaries were deconsolidated from the results of AIG, resulting in a pre-tax loss of $114 million for the year ended December 31, 2022, reported in Net gain (loss) on divestitures and other. In addition, AIGFP and its subsidiaries were determined to be an unconsolidated variable interest entity . USE OF ESTIMATES The preparation of financial statements in accordance with U.S. GAAP requires the application of accounting policies that often involve a significant degree of judgment. Accounting policies that we believe are most dependent on the application of estimates and assumptions are considered our critical accounting estimates and are related to the determination of: • loss reserves; • reinsurance assets, including the allowance for credit losses and disputes; • allowance for credit losses on certain investments, primarily on loans and available for sale fixed maturity securities; • fair value measurements of certain financial assets and financial liabilities; • income taxes, in particular the recoverability of our deferred tax asset and establishment of provisions for uncertain tax positions; and • goodwill impairment.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies The following list identifies our significant accounting policies presented in other Notes to these Consolidated Financial Statements, with a reference to the Note where a detailed description can be found: Note 6. Investments • Fixed maturity and equity securities • Other invested assets • Net investment income • Net realized gains (losses) • Allowance for credit losses Note 7. Lending Activities • Mortgage and other loans receivable – net of allowance Note 8. Reinsurance • Reinsurance assets – net of allowance • Retroactive reinsurance Note 9. Deferred Policy Acquisition Costs Note 10. Variable Interest Entities Note 11. Derivatives and Hedge Accounting • Derivative assets and liabilities, at fair value Note 12. Goodwill and Other Intangible Assets Note 13. Insurance Liabilities • Liability for unpaid losses and loss adjustment expenses • Discounting of reserves Note 14. Debt • Long-term debt • Debt of consolidated investment entities Note 15. Contingencies, Commitments and Guarantees • Legal contingencies Note 17. Earnings Per Common Share (EPS) Note 21. Income Taxes OTHER SIGNIFICANT ACCOUNTING POLICIES Premiums are presented net of reinsurance, as applicable. Premiums for short-duration contracts are recorded as written on the inception date of the policy. Premiums are earned primarily on a pro rata basis over the term of the related coverage. Sales of extended services contracts are reflected as premiums written and earned on a pro rata basis over the term of the related coverage. In addition, certain miscellaneous income is included as premiums written and earned. The reserve for unearned premiums includes the portion of premiums written relating to the unexpired terms of coverage. Reinsurance premiums are typically earned over the same period as the underlying policies or risks covered by the contract. As a result, the earnings pattern of a reinsurance contract may extend up to 24 months, reflecting the inception dates of the underlying policies throughout the year. Premiums from long-duration life products, other than universal and variable life contracts, are recognized as revenues when due. Reinsurance premiums for assumed business are estimated based on information received from ceding companies and reinsurers. Any subsequent differences that arise regarding such estimates are recorded in the periods in which they are determined. Cash represents cash on hand and demand deposits. Short-term investments include interest bearing investments and time deposits. Securities included within short-term investments are stated at estimated fair value. Premiums and other receivables – net of allowance for credit losses and disputes include premium balances receivable, amounts due from agents and brokers and policyholders, receivables resulting from sales of securities that had not yet settled, cash collateral posted to derivative counterparties that is not eligible to be netted against derivative liabilities and other receivables. Deposit assets and liabilities We have entered into certain insurance and reinsurance contracts that do not contain sufficient insurance risk to be accounted for as insurance or reinsurance. When we receive premiums on such contracts, the premiums received, after deduction for certain related expenses, are recorded as deposits within Deposit accounting liabilities in the Consolidated Balance Sheets. Net proceeds of these deposits are invested and generate Net investment income. When we pay premiums on such contracts, the premiums paid are recorded as deposits within Deposit accounting assets in the Consolidated Balance Sheets. The deposit asset or liability is adjusted as amounts are paid, consistent with the underlying contracts. Deferred gains on retroactive reinsurance agreements are also reflected within deposit accounting liabilities. Other assets consist of prepaid expenses, deposits, other deferred charges, real estate, other fixed assets, capitalized software costs, goodwill, intangible assets other than goodwill, restricted cash, derivative assets, and accrued interest income. The cost of buildings and furniture and equipment is depreciated principally on the straight-line basis over their estimated useful lives (maximum of 40 years for buildings and 10 years for furniture and fixtures). Expenditures for maintenance and repairs are charged to income as incurred and expenditures for improvements are capitalized and depreciated. We periodically assess the carrying amount of our real estate for purposes of determining any asset impairment. Capitalized software costs, which represent costs directly related to obtaining, developing or upgrading internal use software, are capitalized and amortized using the straight-line method over a period generally not exceeding ten years. Other liabilities consist of other funds on deposit, other payables, securities sold under agreements to repurchase, securities sold but not yet purchased, liabilities resulting from purchases of securities that have not yet settled, derivative liabilities, cash collateral received from derivative counterparties that contractually cannot be netted against derivative assets and allowance for credit losses in relation to off-balance sheet commitments. Foreign currency Financial statement accounts expressed in foreign currencies are translated into U.S. dollars. Functional currency assets and liabilities are translated into U.S. dollars generally using rates of exchange prevailing at the balance sheet date of each respective subsidiary and the related translation adjustments are recorded as a separate component of Accumulated other comprehensive income, net of any related taxes, in Total AIG shareholders’ equity. Income statement accounts expressed in functional currencies are translated using average exchange rates during the period. Functional currencies are generally the currencies of the local operating environment. Financial statement accounts expressed in currencies other than the functional currency of a consolidated entity are remeasured into that entity’s functional currency resulting in exchange gains or losses recorded in income. The adjustments resulting from translation of financial statements of foreign entities operating in highly inflationary economies are recorded in income. Non-redeemable noncontrolling interest is the portion of equity (net assets) and net income (loss) in a subsidiary not attributable, directly or indirectly, to AIG. ACCOUNTING STANDARDS ADOPTED DURING 2024 Fair Value Measurement On June 30, 2022, the Financial Accounting Standards Board (FASB) issued an accounting standards update to address diversity in practice by clarifying that a contractual sale restriction should not be considered in the measurement of the fair value of an equity security. It also requires entities with investments in equity securities subject to contractual sale restrictions to disclose certain qualitative and quantitative information about such securities. The Company adopted the standard on January 1, 2024, prospectively for entities other than investment companies. The adoption of the standard did not have a material impact on AIG Consolidated Financial Statements. Segment Reporting In November 2023, the FASB issued an accounting standard update to address improvements to reportable segment disclosures. The standard primarily requires the following disclosure on an annual and interim basis: (i) significant segment expenses that are regularly provided to the chief operating decision makers (CODMs) and included within each reported measure of segment profit or loss; and (ii) other segment items and description of its composition. The standard also requires current annual disclosures about a reportable segment's profits or losses and assets to be disclosed in interim periods and the title and position of the CODMs with an explanation of how the CODMs uses the reported measure(s) of segment profits or losses in assessing segment performance. The Company adopted the standard for its 2024 Annual Report on Form 10-K, retrospectively. For additional detail, see Note 3 FUTURE APPLICATION OF ACCOUNTING STANDARDS Income Tax In December 2023, the FASB issued an accounting standard update to address improvements to income tax disclosures. The standard requires disaggregated information about a company’s effective tax rate reconciliation as well as information on income taxes paid. The standard is effective for public companies for annual periods beginning after December 15, 2024, with early adoption permitted. The standard should be applied on a prospective basis, but retrospective application is permitted. We are assessing the impact of this standard. Disaggregation of Income Statement Expenses

Segment Reporting [Abstract]
Segment Information	3. Segment Information In the fourth quarter of 2024, the Company realigned its organizational structure and the composition of its reportable segments to reflect changes in how the Company manages its operations, specifically the level at which its chief operating decision makers (CODMs) regularly review operating results and allocate resources. Our CODMs are the chief executive officer (CEO) and chief financial officer (CFO). The CODMs evaluate performance of the segments based on underwriting income (loss). The CODMs use this measure to benchmark AIG’s performance, assessing performance of the segments and in establishing management’s compensation. AIG has three reportable segments: North America Commercial, International Commercial and Global Personal. Prior years’ presentations have been recast to conform to the new reportable segments. Our General Insurance business (General Insurance) consists of our three segments and the Net investment income related to our insurance operations. NORTH AMERICA COMMERCIAL North America Commercial consists of insurance businesses in the United States, Canada and Bermuda. INTERNATIONAL COMMERCIAL International Commercial consists of insurance businesses in Japan, the United Kingdom, Europe, Middle East and Africa (EMEA region), Asia Pacific, Latin America and Caribbean, and China. International also includes the results of Talbot Underwriting Ltd. as well as AIG’s Global Specialty business. GLOBAL PERSONAL Global Personal consists primarily of insurance businesses in the United States as well as Japan, the United Kingdom, Europe, Middle East and Africa (EMEA region), Asia Pacific, Latin America and Caribbean, and China. PRODUCTS The segments consist of the following products: – North America and International Commercial consists of Property & Short Tail, Casualty, Financial Lines and Global Specialty. – Global Personal consists of Global Accident & Health and Personal Lines. For further discussion on recent activity in the General Insurance business, see Note 1. OTHER OPERATIONS Other Operations predominantly consists of Net Investment Income from our AIG Parent liquidity portfolio, Corebridge dividend income, corporate General operating expenses, and Interest expense. SEGMENT RESULTS Management uses Underwriting income (loss) as the basis for the segment performance reviews. AIG calculates Underwriting income (loss) by subtracting Losses and loss adjustment expense incurred, Amortization of DAC, Other acquisition cost, and General operating expense from Net premiums earned. Assets by reportable segment are not used by the CODMs for purposes of making decisions about allocating resources to the segment and assessing its performance.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations Presentation	4. Discontinued Operations Presentation DISCONTINUED OPERATIONS PRESENTATION We present a business, or a component of an entity, as discontinued operations if a) it meets the held-for-sale criteria, or is disposed of by sale, or is disposed of other than by sale, and b) the disposal of the business, or component of an entity, represents a strategic shift that has (or will have) a major effect on AIG’s financial results. Pre-Deconsolidation of Corebridge Corebridge completed its initial public offering in September 2022 and AIG continued to sell its interest in Corebridge through secondary offerings. On May 16, 2024, AIG entered into a stock purchase agreement with Corebridge and Nippon Life Insurance Company (Nippon). On June 3, 2024, AIG closed on a secondary offering of 30 million shares of Corebridge common stock. The sale was recorded as an equity transaction as AIG controlled Corebridge as of the transaction date. The aggregate gross proceeds of the offering, before deducting underwriting discounts and commission and other expenses payable by AIG, were $876 million. As a result of the offering, AIG recorded an increase of $261 million in Total AIG shareholders' equity. Deconsolidation of Corebridge On June 9, 2024, AIG held 48.4 percent of Corebridge common stock, waived its right to majority representation on the Corebridge Board of Directors and one of AIG's designees resigned from the Corebridge Board of Directors as of June 9, 2024 (the Deconsolidation Date). As a result, AIG met the requirements for the deconsolidation of Corebridge. In the second quarter of 2024, AIG recognized a loss of $4.8 billion as a result of the deconsolidation, mainly due to the recognition of an accumulated comprehensive loss of $7.2 billion. The loss is recorded as a component of discontinued operations. The historical financial results of Corebridge, for all periods presented, are reflected in these Consolidated Financial Statements as discontinued operations. In addition, the assets and liabilities of Corebridge are classified as Assets of discontinued operations and Liabilities of discontinued operations in AIG’s Consolidated Balance Sheets as of December 31, 2023. Post Deconsolidation of Corebridge Subsequent to the Deconsolidation Date, AIG elected the fair value option and reflects its retained interest in Corebridge as an equity method investment in Other invested assets using Corebridge’s stock price as its fair value. Dividends received from Corebridge and changes in its stock price are recognized in Net investment income. From August 2024 to November 2024, AIG sold approximately 43 million shares of Corebridge common stocks. The aggregate proceeds received from these transactions were approximately $1.3 billion. On December 9, 2024, AIG completed the sale of approximately 120 million shares of its Corebridge common stock, representing a 21.6 percent ownership stake, to Nippon for $31.47 per share for an aggregate purchase price of $3.8 billion, which resulted in a $282 million gain recognized in Net investment income in the fourth quarter of 2024. Due to share repurchases by Corebridge and sale of shares by AIG after the Deconsolidation Date, as of December 31, 2024, AIG held 22.7 percent of the outstanding common stock of Corebridge.

Fair Value Disclosures [Abstract]
Fair Value Measurements	5. Fair Value Measurements FAIR VALUE MEASUREMENTS ON A RECURRING BASIS We carry certain of our financial instruments at fair value. We define the fair value of a financial instrument as the amount that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We are responsible for the determination of the value of the investments carried at fair value and the supporting methodologies and assumptions. The degree of judgment used in measuring the fair value of financial instruments generally inversely correlates with the level of observable valuation inputs. We maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Financial instruments with quoted prices in active markets generally have more pricing observability and less judgment is used in measuring fair value. Conversely, financial instruments for which no quoted prices are available have less observability and are measured at fair value using valuation models or other pricing techniques that require more judgment. Pricing observability is affected by a number of factors, including the type of financial instrument, whether the financial instrument is new to the market and not yet established, the characteristics specific to the transaction, liquidity and general market conditions. Fair Value Hierarchy Assets and liabilities recorded at fair value in the Consolidated Balance Sheets are measured and classified in accordance with a fair value hierarchy consisting of three “levels” based on the observability of valuation inputs: • Level 1: Fair value measurements based on quoted prices (unadjusted) in active markets that we have the ability to access for identical assets or liabilities. Market price data generally is obtained from exchange or dealer markets. We do not adjust the quoted price for such instruments. • Level 2: Fair value measurements based on inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. • Level 3: Fair value measurements based on valuation techniques that use significant inputs that are unobservable. Both observable and unobservable inputs may be used to determine the fair values of positions classified in Level 3. The circumstances for using these measurements include those in which there is little, if any, market activity for the asset or liability. Therefore, we must make certain assumptions about the inputs a hypothetical market participant would use to value that asset or liability. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The following is a description of the valuation methodologies used for instruments carried at fair value. These methodologies are applied to assets and liabilities across the levels discussed above, and the observability of the inputs used determines the appropriate level in the fair value hierarchy for the respective asset or liability. VALUATION METHODOLOGIES OF FINANCIAL INSTRUMENTS MEASURED AT FAIR VALUE Incorporation of Credit Risk in Fair Value Measurements • Our Own Credit Risk. Fair value measurements for certain liabilities incorporate our own credit risk by determining the explicit cost for each counterparty to protect against its net credit exposure to us at the balance sheet date by reference to observable AIG credit default swaps (CDS) or cash bond spreads. We calculate the effect of credit spread changes using discounted cash flow techniques that incorporate current market interest rates. A derivative counterparty’s net credit exposure to us is determined based on master netting agreements, when applicable, which take into consideration all derivative positions with us, as well as collateral we post with the counterparty at the balance sheet date. • Counterparty Credit Risk. Fair value measurements for freestanding derivatives incorporate counterparty credit by determining the explicit cost for us to protect against our net credit exposure to each counterparty at the balance sheet date by reference to observable counterparty CDS spreads, when available. When not available, other directly or indirectly observable credit spreads will be used to derive the best estimates of the counterparty spreads. Our net credit exposure to a counterparty is determined based on master netting agreements, which take into consideration all derivative positions with the counterparty, as well as collateral posted by the counterparty at the balance sheet date. Fair values for fixed maturity securities based on observable market prices for identical or similar instruments implicitly incorporate counterparty credit risk. Fair values for fixed maturity securities based on internal models incorporate counterparty credit risk by using discount rates that take into consideration cash issuance spreads for similar instruments or other observable information. For fair values measured based on internal models, the cost of credit protection is determined under a discounted present value approach considering the market levels for single name CDS spreads for each specific counterparty, the mid-market value of the net exposure (reflecting the amount of protection required) and the weighted average life of the net exposure. CDS spreads are provided to us by an independent third party. We utilize an interest rate based on the appropriate benchmark curve to derive our discount rates. While this approach does not explicitly consider all potential future behavior of the derivative transactions or potential future changes in valuation inputs, we believe this approach provides a reasonable estimate of the fair value of the assets and liabilities, including consideration of the impact of non-performance risk. Fixed Maturity Securities Whenever available, we obtain quoted prices in active markets for identical assets at the balance sheet date to measure fixed maturity securities at fair value. Market price data is generally obtained from dealer markets. We employ independent third-party valuation service providers to gather, analyze, and interpret market information to derive fair value estimates for individual investments, based upon market-accepted methodologies and assumptions. The methodologies used by these independent third-party valuation service providers are reviewed and understood by management, through periodic discussion with and information provided by the independent third-party valuation service providers. In addition, as discussed further below, control processes designed to ensure the accuracy of these values are applied to the fair values received from independent third-party valuation service providers. Valuation service providers typically obtain data about market transactions and other key valuation model inputs from multiple sources and, through the use of market-accepted valuation methodologies, which may utilize matrix pricing, financial models, accompanying model inputs and various assumptions, provide a single fair value measurement for individual securities. The inputs used by the valuation service providers include, but are not limited to, market prices from completed transactions for identical securities and transactions for comparable securities, benchmark yields, interest rate yield curves, credit spreads, prepayment rates, default rates, recovery assumptions, currency rates, quoted prices for similar securities and other market-observable information, as applicable. If fair value is determined using financial models, these models generally take into account, among other things, market observable information as of the measurement date as well as the specific attributes of the security being valued, including its term, interest rate, credit rating, industry sector, and when applicable, collateral quality and other security or issuer-specific information. When market transactions or other market observable data is limited, the extent to which judgment is applied in determining fair value is greatly increased. We have control processes designed to ensure that the fair values received from independent third-party valuation service providers are accurately recorded, that their data inputs and valuation techniques are appropriate and consistently applied and that the assumptions used appear reasonable and consistent with the objective of determining fair value. We assess the reasonableness of individual security values received from independent third-party valuation service providers through various analytical techniques, and have procedures to escalate related questions internally and to the independent third-party valuation service providers for resolution. To assess the degree of pricing consensus among various valuation service providers for specific asset types, we conduct comparisons of prices received from available sources. We use these comparisons to establish a hierarchy for the fair values received from independent third-party valuation service providers to be used for particular security classes. We also validate prices for selected securities through reviews by members of management who have relevant expertise and who are independent of those charged with executing investing transactions. When our independent third-party valuation service providers are unable to obtain sufficient market observable information upon which to estimate the fair value for a particular security, fair value is determined either by requesting brokers who are knowledgeable about these securities to provide a price quote, which is generally non-binding, or by employing market accepted valuation models internally or via our third party asset managers. Broker prices may be based on an income approach, which converts expected future cash flows to a single present value amount, with specific consideration of inputs relevant to particular security types. For structured securities, such inputs may include ratings, collateral types, geographic concentrations, underlying loan vintages, loan delinquencies and defaults, loss severity assumptions, prepayments, and weighted average coupons and maturities. When the volume or level of market activity for a security is limited, certain inputs used to determine fair value may not be observable in the market. Broker prices may also be based on a market approach that considers recent transactions involving identical or similar securities. Fair values provided by brokers are subject to similar control processes to those noted above for fair values from independent third-party valuation service providers, including management reviews. For those corporate debt instruments (for example, private placements) that are not traded in active markets or that are subject to transfer restrictions, valuations reflect illiquidity and non-transferability, based on available market evidence. When observable price quotations are not available, fair value is determined based on discounted cash flow models using discount rates based on credit spreads, yields or price levels of comparable securities, adjusted for illiquidity and structure. Fair values determined internally or via our third party asset managers are also subject to management review to ensure that valuation models and related inputs are reasonable. The methodology above is relevant for all fixed maturity securities including residential mortgage backed securities (RMBS), commercial mortgage backed securities (CMBS), collateralized loan obligations (CLO), other asset‑backed securities (ABS) and fixed maturity securities issued by government sponsored entities and corporate entities. Equity Securities Traded in Active Markets Whenever available, we obtain quoted prices in active markets for identical assets at the balance sheet date to measure equity securities at fair value. Market price data is generally obtained from exchange or dealer markets. Mortgage and Other Loans Receivable We estimate the fair value of mortgage and other loans receivable that are measured at fair value by using dealer quotations, discounted cash flow analyses and/or internal valuation models. The determination of fair value considers inputs such as interest rate, maturity, the borrower’s creditworthiness, collateral, subordination, guarantees, past-due status, yield curves, credit curves, prepayment rates, market pricing for comparable loans and other relevant factors. Other Invested Assets We initially estimate the fair value of investments in certain hedge funds, private equity funds and other investment partnerships by reference to the transaction price. Subsequently, we generally obtain the fair value of these investments from net asset value information provided by the general partner or manager of the investments, the financial statements of which are generally audited annually. We consider observable market data and perform certain control procedures to validate the appropriateness of using the net asset value as a fair value measurement. The fair values of other investments carried at fair value, such as direct private equity holdings, are initially determined based on transaction price and are subsequently estimated based on available evidence such as market transactions in similar instruments, other financing transactions of the issuer and other available financial information for the issuer, with adjustments made to reflect illiquidity as appropriate. AIG's retained investments in Corebridge, for which we have elected the fair value option, is determined using Corebridge's stock price as its fair value. Short-term Investments For short-term investments that are measured at amortized cost, the carrying amounts of these assets approximate fair values because of the relatively short period of time between origination and expected realization, and their limited exposure to credit risk. Securities purchased under agreements to resell (reverse repurchase agreements) are generally treated as collateralized receivables. We report certain receivables arising from securities purchased under agreements to resell as Short-term investments in the Consolidated Balance Sheets. When these receivables are measured at fair value, we use market-observable interest rates to determine fair value. Freestanding Derivatives Derivative assets and liabilities can be exchange-traded or traded over-the-counter (OTC). We generally value exchange-traded derivatives such as futures and options using quoted prices in active markets for identical derivatives at the balance sheet date. OTC derivatives are valued using market transactions and other market evidence whenever possible, including market-based inputs to models, model calibration to market clearing transactions, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency. When models are used, the selection of a particular model to value an OTC derivative depends on the contractual terms of, and specific risks inherent in the instrument, as well as the availability of pricing information in the market. We generally use similar models to value similar instruments. Valuation models require a variety of inputs, including contractual terms, market prices and rates, yield curves, credit curves, measures of volatility, prepayment rates and correlations of such inputs. For OTC derivatives that trade in liquid markets, such as generic forwards, swaps and options, model inputs can generally be corroborated by observable market data by correlation or other means, and model selection does not involve significant management judgment. For certain OTC derivatives that trade in less liquid markets, where we generally do not have corroborating market evidence to support significant model inputs and cannot verify the model to market transactions, the transaction price may provide the best estimate of fair value. Accordingly, when a pricing model is used to value such an instrument, the model is adjusted so the model value at inception equals the transaction price. We will update valuation inputs in these models only when corroborated by evidence such as similar market transactions, independent third-party valuation service providers and/or broker or dealer quotations, or other empirical market data. When appropriate, valuations are adjusted for various factors such as liquidity, bid/offer spreads and credit considerations. Such adjustments are generally based on available market evidence. In the absence of such evidence, management’s best estimate is used. We value our super senior credit default swap portfolio using prices obtained from vendors and/or counterparties. The valuation of the super senior credit derivatives is complex because of the limited availability of market observable information due to the lack of trading and price transparency in certain structured finance markets. Our valuation methodologies for the super senior CDS portfolio have evolved over time in response to market conditions and the availability of market observable information. We have sought to calibrate the methodologies to available market information and to review the assumptions of the methodologies on a regular basis. Fortitude Re funds withheld payable The reinsurance transactions between AIG and Fortitude Re were structured as modco and loss portfolio transfer arrangements with funds withheld (funds withheld). AIG has established a funds withheld payable to Fortitude Re while simultaneously establishing a reinsurance asset representing reserves for the insurance coverage that Fortitude Re has assumed. The funds withheld payable contains an embedded derivative and changes in fair value of the embedded derivative related to the funds withheld payable are recognized in earnings through realized gains (losses). This embedded derivative is considered a total return swap with contractual returns that are attributable to various assets and liabilities associated with these reinsurance agreements. Other Liabilities Other liabilities measured at fair value include certain securities sold under agreements to repurchase and certain securities sold but not yet purchased. Liabilities arising from securities sold under agreements to repurchase are generally treated as collateralized borrowings. We estimate the fair value of liabilities arising under these agreements by using market-observable interest rates. This methodology considers such factors as the coupon rate, yield curves and other relevant factors. Fair values for securities sold but not yet purchased are based on current market prices.

Both observable and unobservable inputs may be used to determine the fair values of positions classified in Level 3 in the tables above. As a result, the unrealized gains (losses) on instruments held at December 31, 2024 and 2023 may include changes in fair value that were attributable to both observable (e.g., changes in market interest rates) and unobservable inputs (e.g., changes in unobservable long-dated volatilities). Transfers of Level 3 Assets and Liabilities The Net realized and unrealized gains (losses) included in income (loss) or Other comprehensive income (loss) (OCI) as shown in the table above excludes $(35) million and $2 million of net gains (losses) related to assets and liabilities transferred into Level 3 during the years ended December 31, 2024 and 2023, respectively, and includes $(13) million and $(11) million of net gains (losses) related to assets and liabilities transferred out of Level 3 during the years ended December 31, 2024 and 2023, respectively. Transfers of Level 3 Assets During the years ended December 31, 2024 and 2023, transfers into Level 3 assets primarily included certain investments in private placement corporate debt, commercial mortgage-backed securities (CMBS), residential mortgage-backed securities (RMBS), collateralized loan obligations (CLO)/asset-backed securities (ABS) and equity securities. Transfers of private placement corporate debt and certain ABS into Level 3 assets were primarily the result of limited market pricing information that required us to determine fair value for these securities based on inputs that are adjusted to better reflect our own assumptions regarding the characteristics of a specific security or associated market liquidity. The transfers of investments in CMBS, RMBS, CLO and certain ABS into Level 3 assets were due to diminished market transparency and liquidity for individual security types. During the years ended December 31, 2024 and 2023, transfers out of Level 3 assets primarily included certain investments in private placement corporate debt, CMBS, RMBS, CLO/ABS, municipal bonds and equity securities. Transfers of private placement corporate debt out of Level 3 assets were based on consideration of market liquidity as well as related transparency of pricing and associated observable inputs for these invest

Investments, Debt and Equity Securities [Abstract]
Investments	6. Investments FIXED MATURITY SECURITIES Bonds held to maturity are carried at amortized cost when we have the ability and positive intent to hold these securities until maturity. When we do not have the ability or positive intent to hold bonds until maturity, these securities are classified as available for sale or the fair value option has been elected. None of our fixed maturity securities met the criteria for held to maturity classification at December 31, 2024 or 2023. Unrealized gains and losses from available for sale investments in fixed maturity securities carried at fair value were reported as a separate component of AOCI, net of deferred income taxes, in shareholders’ equity. Realized and unrealized gains and losses from fixed maturity securities for which the fair value option has been elected are reflected in Net investment income. Investments in fixed maturity securities are recorded on a trade-date basis. Interest income is recognized using the effective yield method and reflects amortization of premium and accretion of discount. Premiums and discounts arising from the purchase of bonds classified as available for sale are treated as yield adjustments over their estimated holding periods, until maturity, or call date, if applicable. For investments in certain structured securities, recognized yields are updated based on current information regarding the timing and amount of expected undiscounted future cash flows. For high credit quality structured securities, effective yields are recalculated based on actual payments received and updated prepayment expectations, and the amortized cost is adjusted to the amount that would have existed had the new effective yield been applied since acquisition with a corresponding charge or credit to net investment income. For structured securities that are not high credit quality, the structured securities yields are based on expected cash flows which take into account both expected credit losses and prepayments. An allowance for credit losses is not established upon initial recognition of the asset (unless the security is determined to be a purchased credit deteriorated (PCD) asset which is discussed in more detail below). Subsequently, differences between actual and expected cash flows and changes in expected cash flows are recognized as adjustments to the allowance for credit losses. Changes that cannot be reflected as adjustments to the allowance for credit losses are accounted for as prospective adjustments to yield. SECURITIES AVAILABLE FOR SALE The following table presents the amortized cost and fair value of our available for sale securities: (in millions) Amortized Cost Allowance for Credit Losses (a) Gross Unrealized Gains Gross Unrealized Losses Fair Value December 31, 2024 Bonds available for sale: U.S. government and government sponsored entities $ 3,346 $ — $ 20 $ (99) $ 3,267 Obligations of states, municipalities and political subdivisions 3,223 — 32 (112) 3,143 Non-U.S. governments 8,644 (1) 54 (590) 8,107 Corporate debt 33,031 (28) 581 (1,758) 31,826 Mortgage-backed, asset-backed and collateralized: RMBS 8,820 (6) 209 (419) 8,604 CMBS 3,988 (3) 32 (91) 3,926 CLO/ABS 5,143 — 34 (44) 5,133 Total mortgage-backed, asset-backed and collateralized 17,951 (9) 275 (554) 17,663 Total bonds available for sale (b) $ 66,195 $ (38) $ 962 $ (3,113) $ 64,006 December 31, 2023 Bonds available for sale: U.S. government and government sponsored entities $ 4,444 $ — $ 40 $ (89) $ 4,395 Obligations of states, municipalities and political subdivisions 4,930 — 60 (157) 4,833 Non-U.S. governments 8,973 (1) 94 (670) 8,396 Corporate debt 34,013 (20) 606 (2,253) 32,346 Mortgage-backed, asset-backed and collateralized: RMBS 6,423 (9) 219 (426) 6,207 CMBS 4,326 (4) 23 (198) 4,147 CLO/ABS 5,010 — 31 (123) 4,918 Total mortgage-backed, asset-backed and collateralized 15,759 (13) 273 (747) 15,272 Total bonds available for sale (b) $ 68,119 $ (34) $ 1,073 $ (3,916) $ 65,242 (a) Represents the allowance for credit losses that has been recognized. Changes in the allowance for credit losses are recorded through Net realized gains (losses) and are not recognized in OCI. (b) At December 31, 2024 and 2023, the fair value of bonds available for sale held by us that were below investment grade or not rated totaled $3.6 billion or 6 percent and $5.2 billion or 8 percent, respectively. Securities Available for Sale in a Loss Position for Which No Allowance for Credit Loss Has Been Recorded The following table summarizes the fair value and gross unrealized losses on our available for sale securities, aggregated by major investment category and length of time that individual securities have been in a continuous unrealized loss position for which no allowance for credit loss has been recorded: Less than 12 Months 12 Months or More Total (in millions) Fair Gross Fair Gross Fair Gross December 31, 2024 Bonds available for sale: U.S. government and government sponsored entities $ 1,718 $ 21 $ 358 $ 78 $ 2,076 $ 99 Obligations of states, municipalities and political subdivisions 1,502 33 586 79 2,088 112 Non-U.S. governments 1,964 55 3,446 534 5,410 589 Corporate debt 10,347 234 10,907 1,515 21,254 1,749 RMBS 3,711 58 2,147 343 5,858 401 CMBS 1,052 18 992 71 2,044 89 CLO/ABS 1,368 9 315 35 1,683 44 Total bonds available for sale $ 21,662 $ 428 $ 18,751 $ 2,655 $ 40,413 $ 3,083 Less than 12 Months 12 Months or More Total (in millions) Fair Gross Fair Gross Fair Gross December 31, 2023 Bonds available for sale: U.S. government and government sponsored entities $ 1,027 $ 10 $ 804 $ 79 $ 1,831 $ 89 Obligations of states, municipalities and political subdivisions 850 24 1,602 133 2,452 157 Non-U.S. governments 1,431 87 4,503 583 5,934 670 Corporate debt 4,089 171 18,612 2,070 22,701 2,241 RMBS 1,456 114 2,385 300 3,841 414 CMBS 1,024 54 1,622 137 2,646 191 CLO/ABS 1,371 33 1,509 90 2,880 123 Total bonds available for sale $ 11,248 $ 493 $ 31,037 $ 3,392 $ 42,285 $ 3,885 At December 31, 2024, we held 12,274 individual fixed maturity securities that were in an unrealized loss position and for which no allowance for credit losses has been recorded (including 5,984 individual fixed maturity securities that were in a continuous unrealized loss position for 12 months or more). At December 31, 2023, we held 13,052 individual fixed maturity securities that were in an unrealized loss position and for which no allowance for credit losses has been recorded (including 10,027 individual fixed maturity securities that were in a continuous unrealized loss position for 12 months or more). We did not recognize the unrealized losses in earnings on these fixed maturity securities at December 31, 2024 because it was determined that such losses were due to non-credit factors. Additionally, we neither intend to sell the securities nor do we believe that it is more likely than not that we will be required to sell these securities before recovery of their amortized cost basis. For fixed maturity securities with significant declines, we performed fundamental credit analyses on a security-by-security basis, which included consideration of credit enhancements, liquidity position, expected defaults, industry and sector analysis, forecasts and available market data. Contractual Maturities of Fixed Maturity Securities Available for Sale The following table presents the amortized cost and fair value of fixed maturity securities available for sale by contractual maturity: December 31, 2024 Total Fixed Maturity Securities (in millions) Amortized Cost, Fair Value Due in one year or less $ 4,070 $ 3,980 Due after one year through five years 22,194 22,163 Due after five years through ten years 15,712 15,010 Due after ten years 6,239 5,190 Mortgage-backed, asset-backed and collateralized 17,942 17,663 Total $ 66,157 $ 64,006 Actual maturities may differ from contractual maturities because certain borrowers have the right to call or prepay certain obligations with or without call or prepayment penalties.

Private equity funds investments include limited partnerships, direct equities and real estate partnerships. Also includes investments in real estate, net of accumulated depreciation. At December 31, 2024 and 2023, the accumulated depreciation was $161 million and $161 million, respectively. (b) All other investments include mainly bank deposits with a maturity greater than one year and investments in joint ventures with strategic partners. Other Invested Assets Carried at Fair Value Certain hedge funds, private equity funds, and other investment partnerships for which we have elected the fair value option are reported at fair value with changes in fair value recognized in Net investment income. Other Invested Assets – Equity Method Investments We account for hedge funds, private equity funds and other investment partnerships using the equity method of accounting unless our interest is so minor that we may have virtually no influence over partnership operating and financial policies, or we have elected the fair value option. Under the equity method of accounting, our carrying amount generally is our share of the net asset value of the funds or the partnerships, and changes in our share of the net asset values are recorded in Net investment income. In applying the equity method of accounting, we consistently use the most recently available financial information provided by the general partner or manager of each of these investments. Hedge funds are reported as of the balance sheet date. Private equity funds are generally reported on a one-quarter lag. The financial statements of these investees are generally audited annually. The carrying amount of equity method investments totaled $6.6 billion and $3.0 billion as of December 31, 2024 and 2023, respectively. Summarized Financial Information of Equity Method Investees The following is the aggregated summarized financial information of our equity method investees, including those for which the fair value option has been elected: Years Ended December 31, (in millions) 2024* 2023 2022 Operating results: Total revenues $ 21,860 $ 2,320 $ 6,486 Total expenses (18,557) (1,668) (1,832) Income before income taxes $ 3,303 $ 652 $ 4,654 At December 31, (in millions) 2024* 2023 Balance sheet: Total assets $ 418,639 $ 28,264 Total liabilities $ (383,643) $ (5,196) * 2024 includes investment in Corebridge. Other Investments Also included in Other invested assets are real estate held for investment. These investments are reported at cost, less depreciation and are subject to impairment review, as discussed below. NET INVESTMENT INCOME Net investment income represents income primarily from the following sources: • Interest income and related expenses, including amortization of premiums and accretion of discounts with changes in the timing and the amount of expected principal and interest cash flows reflected in yield, as applicable. • Dividend income from common and preferred stocks. • Realized and unrealized gains and losses from investments in other securities and investments for which we elected the fair value option. • Earnings from alternative investments. • Prepayment premiums. The following table presents the components of Net investment income: Years Ended December 31, 2024 2023 2022 (in millions) Excluding Fortitude Total Excluding Fortitude Total Excluding Fortitude Total Available for sale fixed maturity securities, including short-term investments $ 2,989 $ 89 $ 3,078 $ 2,862 $ 95 $ 2,957 $ 1,960 $ 113 $ 2,073 Other fixed maturity securities (a) — 19 19 3 43 46 (282) (92) (374) Equity securities 149 — 149 53 — 53 29 — 29 Interest on mortgage and other loans 229 32 261 283 38 321 264 27 291 Alternative investments (b) 196 — 196 199 — 199 315 — 315 Other investments (c)(d) 727 4 731 101 4 105 211 5 216 Total investment income 4,290 144 4,434 3,501 180 3,681 2,497 53 2,550 Investment expenses 179 — 179 235 — 235 180 — 180 Net investment income $ 4,111 $ 144 $ 4,255 $ 3,266 $ 180 $ 3,446 $ 2,317 $ 53 $ 2,370 (a) Included in the year ended December 31, 2022 was losses of $195 million related to fixed maturity securities measured at fair value that economically hedge liabilities described in (c) below. (b) Includes income from hedge funds, private equity funds and real estate investments. Hedge funds are recorded as of the balance sheet date. Private equity funds are generally reported on a one-quarter lag. (c) Included in the year ended December 31, 2022 was income of $186 million related to liabilities measured at fair value that are economically hedged with fixed maturity securities as described in (a) above. (d) Includes dividends received from Corebridge, changes in its stock price and gain on sale of shares of $162 million and $439 million, respectively, for the year ended December 31, 2024. NET REALIZED GAINS AND LOSSES Net realized gains and losses are determined by specific identification. The net realized gains and losses are generated primarily from the following sources: • Sales of available for sale fixed maturity securities, real estate and other alternative investments. • Reductions to the amortized cost basis of available for sale fixed maturity securities that have been written down due to our intent to sell them or it being more likely than not that we will be required to sell them. • Changes in the allowance for credit losses on bonds available for sale, mortgage and other loans receivable, and loans commitments. • Most changes in the fair value of free standing and embedded derivatives, including changes in the non-performance adjustment are included in Net realized gains (losses). However, changes in derivatives designated as hedging instruments when the fair value of the hedged item is not reported in Net realized gains (losses) are excluded from Net realized gains (losses). • Foreign exchange gains and losses resulting from foreign currency transactions. • Changes in fair value of the embedded derivative related to the Fortitude Re funds withheld assets.

EVALUATING INVESTMENTS FOR AN ALLOWANCE FOR CREDIT LOSSES AND IMPAIRMENTS Fixed Maturity Securities If we intend to sell a fixed maturity security or it is more likely than not that we will be required to sell a fixed maturity security before recovery of its amortized cost basis and if the fair value of the security is below amortized cost, an impairment has occurred and the amortized cost is written down to current fair value, with a corresponding charge to Net realized gains (losses). No allowance is established in these situations and any previously recorded allowance is reversed. The new cost basis is not adjusted for subsequent increases in estimated fair value. When assessing our intent to sell a fixed maturity security, or whether it is more likely than not that we will be required to sell a fixed maturity security before recovery of its amortized cost basis, management evaluates relevant facts and circumstances including, but not limited to, decisions to reposition our investment portfolio, sales of securities to meet cash flow needs and sales of securities to take advantage of favorable pricing. For fixed maturity securities for which a decline in the fair value below the amortized cost is due to credit related factors, an allowance is established for the difference between the estimated recoverable value and amortized cost with a corresponding charge to Net realized gains (losses). The allowance for credit losses is limited to the difference between amortized cost and fair value. The estimated recoverable value is the present value of cash flows expected to be collected, as determined by management. The difference between fair value and amortized cost that is not associated with credit related factors is presented in unrealized appreciation (depreciation) of fixed maturity securities on which an allowance for credit losses was previously recognized (a separate component of AOCI). Accrued interest is excluded from the measurement of the allowance for credit losses. When estimating future cash flows for structured fixed maturity securities (e.g., RMBS, CMBS, CLO, ABS) management considers the historical performance of underlying assets and available market information as well as bond-specific structural considerations, such as credit enhancement and the priority of payment structure of the security. In addition, the process of estimating future cash flows includes, but is not limited to, the following critical inputs, which vary by asset class: • Current delinquency rates; • Expected default rates and the timing of such defaults; • Loss severity and the timing of any recovery; and • Expected prepayment speeds. When estimating future cash flows for corporate, municipal and sovereign fixed maturity securities determined to be credit impaired, management considers: • Expected default rates and the timing of such defaults; • Loss severity and the timing of any recovery; and • Scenarios specific to the issuer and the security, which may also include estimates of outcomes of corporate restructurings, political and macroeconomic factors, stability and financial strength of the issuer, the value of any secondary sources of repayment and the disposition of assets. We consider severe price declines in our assessment of potential credit impairments. We may also modify our model inputs when we determine that price movements in certain sectors are indicative of factors not captured by the cash flow models. Under the current expected credit loss (CECL) model, credit losses are reassessed each period. The allowance for credit losses and the corresponding charge to Net realized gains (losses) can be reversed if conditions change, however, the allowance for credit losses will never be reduced below zero. When we determine that all or a portion of a fixed maturity security is uncollectable, the uncollectable amortized cost amount is written off with a corresponding reduction to the allowance for credit losses. If we collect cash flows that were previously written off, the recovery is recognized by recording a gain in Net realized gains (losses). Credit Impairments The following table presents a rollforward of the changes in allowance for credit losses on available for sale fixed maturity securities by major investment category: Years Ended December 31, 2024 2023 2022 (in millions) Structured Non- Total Structured Non- Total Structured Non- Total Balance, beginning of year $ 13 $ 21 $ 34 $ 20 $ 17 $ 37 $ 2 $ 19 $ 21 Additions: Securities for which allowance for credit losses was not previously recorded 5 10 15 6 46 52 32 99 131 Reductions: Securities sold during the period (4) (2) (6) (3) (9) (12) — (45) (45) Addition to (release of) the allowance for credit losses on securities that had an allowance recorded in a previous period, for which there was no intent to sell before recovery of amortized cost basis (3) 13 10 (1) (7) (8) (13) (46) (59) Write-offs charged against the allowance — (24) (24) (11) (26) (37) — (6) (6) Other (1) 10 9 2 — 2 (1) (4) (5) Balance, end of year $ 10 $ 28 $ 38 $ 13 $ 21 $ 34 $ 20 $ 17 $ 37 Purchased Credit Deteriorated Securities We purchase certain RMBS securities that have experienced more-than-insignificant deterioration in credit quality since origination. These are referred to as PCD assets. At the time of purchase an allowance is recognized for these PCD assets by adding it to the purchase price to arrive at the initial amortized cost. There is no credit loss expense recognized upon acquisition of a PCD asset. When determining the initial allowance for credit losses, management considers the historical performance of underlying assets and available market information as well as bond-specific structural considerations, such as credit enhancement and the priority of payment structure of the security. In addition, the process of estimating future cash flows includes, but is not limited to, the following critical inputs: • Current delinquency rates; • Expected default rates and the timing of such defaults; • Loss severity and the timing of any recovery; and • Expected prepayment speeds. Subsequent to the acquisition date, the PCD assets follow the same accounting as other structured securities that are not high credit quality. We did not purchase securities with more than insignificant credit deterioration since their origination during the years ended December 31, 2024, 2023 and 2022. Other Invested Assets Our equity method investments in private equity funds, hedge funds and other entities are evaluated for impairment each reporting period. Such evaluation considers market conditions, events and volatility that may impact the recoverability of the underlying investments within these private equity funds and hedge funds and is based on the nature of the underlying investments and specific inherent risks. Such risks may evolve based on the nature of the underlying investments. Our investments in real estate are periodically evaluated for recoverability whenever changes in circumstances indicate the carrying amount of an asset may be impaired. When impairment indicators are present, we compare expected investment cash flows to carrying amount. When the expected cash flows are less than the carrying amount, the investments are written down to fair value with a corresponding charge to earnings. PLEDGED INVESTMENTS Secured Financing and Similar Arrangements We enter into secured financing transactions whereby certain securities are sold under agreements to repurchase (repurchase agreements), in which we transfer securities in exchange for cash, with an agreement by us to repurchase the same or substantially similar securities. Our secured financing transactions also include those that involve the transfer of securities to financial institutions in exchange for cash (securities lending agreements). In all of these secured financing transactions, the securities transferred by us (pledged collateral) may be sold or repledged by the counterparties. These agreements are recorded at their contracted amounts plus accrued interest, other than those that are accounted for at fair value. Pledged collateral levels are monitored daily and are generally maintained at an agreed-upon percentage of the fair value of the amounts borrowed during the life of the transactions. In the event of a decline in the fair value of the pledged collateral under these secured financing transactions, we may be required to transfer cash or additional securities as pledged collateral under these agreements. At the termination of the transactions, we and our counterparties are obligated to return the amounts borrowed and the securities transferred, respectively. The following table presents the fair value of securities pledged to counterparties under secured financing transactions, including repurchase and securities lending agreements: (in millions) December 31, 2024 December 31, 2023 Fixed maturity securities available for sale $ — $ 106 At December 31, 2024 and 2023, amounts borrowed under repurchase and securities lending agreements totaled $0 million and $107 million, respectively. The following table presents the fair value of securities pledged under our repurchase agreements by collateral type and by remaining contractual maturity: Remaining Contractual Maturity of the Agreements (in millions) Overnight up to 31 - 90 91 - 364 365 days Total December 31, 2023 Bonds available for sale: Non-U.S. governments $ — $ 106 $ — $ — $ — $ 106 Corporate debt — — — — — — Total $ — $ 106 $ — $ — $ — $ 106 We also enter into agreements in which securities are purchased by us under reverse repurchase agreements, which are accounted for as secured financing transactions and reported as short-term investments or other assets, depending on their terms. These agreements are recorded at their contracted resale amounts plus accrued interest, other than those that are accounted for at fair value. In all reverse repurchase transactions, we take possession of or obtain a security interest in the related securities, and we have the right to sell or repledge this collateral received. The following table presents information on the fair value of securities pledged to us under reverse repurchase agreements: (in millions) December 31, 2024 December 31, 2023 Securities collateral pledged to us $ 2,853 $ 1,200 At December 31, 2024 and 2023, the carrying value of reverse repurchase agreements totaled $2.8 billion and $1.1 billion, respectively. All secured financing transactions are collateralized and margined on a daily basis consistent with market standards and subject to enforceable master netting arrangements with rights of set off. We do not currently offset any such transactions. Insurance – Statutory and Other Deposits The total carrying value of cash and securities deposited by our insurance subsidiaries under requirements of regulatory authorities or other insurance-related arrangements and certain reinsurance contracts, was $7.8 billion and $8.4 billion at December 31, 2024 and 2023, respectively. Other Pledges and Restrictions Certain of our subsidiaries are members of Federal Home Loan Banks (FHLBs) and such membership requires the members to own stock in these FHLBs. We owned an aggregate of $13 million and $15 million of stock in FHLBs at December 31, 2024 and 2023, respectively. In addition, our subsidiaries have pledged securities available for sale with a fair value of $1.6 billion at December 31, 2024 and $1.7 billion at December 31, 2023. Investments held in escrow accounts or otherwise subject to restriction as to their use were $73 million and $164 million, comprised of bonds available for sale and short-term investments at December 31, 2024 and 2023, respectively. Reinsurance transactions between AIG and Fortitude Re were structured as modified coinsurance (modco) and loss portfolio transfer arrangements with funds withheld.

Receivables [Abstract]
Lending Activities	7. Lending Activities Mortgage and other loans receivable include commercial mortgages, life insurance policy loans, commercial loans, and other loans and notes receivable. Commercial mortgages, commercial loans, and other loans and notes receivable are carried at unpaid principal balances less allowance for credit losses and plus or minus adjustments for the accretion or amortization of discount or premium. Interest income on such loans is accrued as earned. Direct costs of originating commercial mortgages, commercial loans, and other loans and notes receivable, net of nonrefundable points and fees, are deferred and included in the carrying amount of the related receivables. The amount deferred is amortized to income as an adjustment to earnings using the interest method. Life insurance policy loans are carried at unpaid principal balances. There is no allowance for policy loans because these loans serve to reduce the death benefit paid when the death claim is made and the balances are effectively collateralized by the cash surrender value of the policy. The following table presents the composition of Mortgage and other loans receivable, net: (in millions) December 31, 2024 December 31, 2023 Commercial mortgages (a) $ 3,305 $ 3,836 Life insurance policy loans 6 7 Commercial loans, other loans and notes receivable (b) 721 738 Total mortgage and other loans receivable (c) 4,032 4,581 Allowance for credit losses (c) (d) (164) (140) Mortgage and other loans receivable, net (c) $ 3,868 $ 4,441 (a) Commercial mortgages primarily represent loans for apartments, offices and retail properties, with exposures in California and New York representing the largest geographic concentrations (aggregating approximately 14 percent and 12 percent, respectively, at December 31, 2024 and 13 percent and 10 percent, respectively, at December 31, 2023). (b) There were no loans that were held-for-sale carried at lower of cost or market as of December 31, 2024 and 2023. (c) Excludes $37.6 billion at both December 31, 2024 and 2023 of loans receivable from AIGFP, which has a full allowance for credit losses, recognized upon the deconsolidation of AIGFP. For additional information, see Note 1. (d) Does not include allowance for credit losses of $8 million and $9 million, respectively, at December 31, 2024 and 2023, in relation to off-balance-sheet commitments to fund commercial mortgage loans, which is recorded in Other liabilities. Interest income is not accrued when payment of contractual principal and interest is not expected. Any cash received on impaired loans is generally recorded as a reduction of the current carrying amount of the loan. Accrual of interest income is generally resumed when delinquent contractual principal and interest is repaid or when a portion of the delinquent contractual payments are made and the ongoing required contractual payments have been made for an appropriate period. As of December 31, 2024 and 2023, $252 million and $73 million, respectively, of commercial mortgage loans were placed on nonaccrual status. Accrued interest is presented separately and is included in Accrued investment income on the Consolidated Balance Sheets. As of December 31, 2024 and 2023, accrued interest receivable was $15 million and $21 million, respectively, associated with commercial mortgage loans. A significant majority of commercial mortgages in the portfolio are non-recourse loans and, accordingly, the only guarantees are for specific items that are exceptions to the non-recourse provisions. It is therefore extremely rare for us to have cause to enforce the provisions of a guarantee on a commercial real estate or mortgage loan. Nonperforming loans are generally those loans where payment of contractual principal or interest is more than 90 days past due. Nonperforming loans were not significant for any of the periods presented.

Our weighted average debt service coverage ratio was 1.8x at both periods ended at December 31, 2024 and December 31, 2023. The debt service coverage ratios are updated when additional relevant information becomes available. (b) The loan-to-value ratio compares the current unpaid principal balance of the loan to the estimated fair value of the underlying property collateralizing the loan. Our weighted average loan-to-value ratio was 65 percent and 62 percent at December 31, 2024 and December 31, 2023, respectively. The loan-to-value ratios have been updated within the last three months to reflect the current carrying values of the loans. We update the valuations of collateral properties by obtaining independent appraisals, generally at least once per year.

METHODOLOGY USED TO ESTIMATE THE ALLOWANCE FOR CREDIT LOSSES At the time of origination or purchase, an allowance for credit losses is established for mortgage and other loan receivables and is updated each reporting period. Changes in the allowance for credit losses are recorded in realized losses. This allowance reflects the risk of loss, even when that risk is remote, that is expected over the remaining contractual life of the loan. The allowance for credit losses considers available relevant information about the collectability of cash flows, including information about past events, current conditions, and reasonable and supportable forecasts of future economic conditions. We revert to historical information when we determine that we can no longer reliably forecast future economic assumptions. The allowances for the commercial mortgage loans are estimated utilizing a probability of default and loss given default model. Loss rate factors are determined based on historical data and adjusted for current and forecasted information. The loss rates are applied based on individual loan attributes and considering such data points as loan-to-value ratios, Fair Isaac Corporation scores, and debt service coverage. The estimate of credit losses also reflects management’s assumptions on certain macroeconomic factors that include, but are not limited to, gross domestic product growth, employment, inflation, housing price index, interest rates and credit spreads. Accrued interest is excluded from the measurement of the allowance for credit losses and accrued interest is reversed through interest income once a loan is placed on nonaccrual. When all or a portion of a loan is deemed uncollectible, the uncollectible portion of the carrying amount of the loan is charged off against the allowance. We also have off-balance sheet commitments related to our commercial mortgage loans. The liability for expected credit losses related to these commercial mortgage loan commitments is reported in Other liabilities in the Consolidated Balance Sheets. When a commitment is funded, we record a loan receivable and reclassify the liability for expected credit losses related to the commitment into loan allowance for expected credit losses. Other changes in the liability for expected credit losses on loan commitments are recorded in Net realized gains (losses) in the Consolidated Statements of Income (Loss). The following table presents a rollforward of the changes in the allowance for credit losses on Mortgage and other loans receivable (a)(b) : Years Ended December 31, 2024 2023 2022 (in millions) Commercial Other Total Commercial Other Total Commercial Other Total Allowance, beginning of year $ 138 $ 2 $ 140 $ 109 $ 8 $ 117 $ 123 $ 11 $ 134 Loans charged off — — — (2) — (2) (4) — (4) Net charge-offs — — — (2) — (2) (4) — (4) Addition to (release of) allowance for loan losses 25 (1) 24 31 (6) 25 (10) (3) (13) Allowance, end of year $ 163 $ 1 $ 164 $ 138 $ 2 $ 140 $ 109 $ 8 $ 117 (a) D oes not include allowance for credit losses of $8 million, $9 million and $9 million, respectively, at December 31, 2024, 2023 and 2022 in relation to off-balance-sheet commitments to fund commercial mortgage loans, which is recorded in Other liabilities. (b) Excludes $37.6 billion of loan receivable from AIGFP, which has a full allowance for credit losses, recognized upon the deconsolidation of AIGFP. For additional information, see Note 1. Our expectations and models used to estimate the allowance for losses on commercial mortgage loans are regularly updated to reflect the current economic environment. LOAN MODIFICATIONS The allowance for credit losses incorporates an estimate of lifetime expected credit losses and is recorded on each asset upon asset origination or acquisition. The starting point for the estimate of the allowance for credit losses is historical loss information, which includes losses from modifications of receivables to borrowers experiencing financial difficulty. We use a probability of default/loss given default model to determine the allowance for credit losses for our commercial mortgage loans. An assessment of whether a borrower is experiencing financial difficulty is made on the date of a modification. Because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses utilizing the measurement methodologies used to estimate the allowance, a change to the allowance for credit losses is generally not recorded upon modification. When modifications are executed, they often will be in the form of principal forgiveness, term extensions, interest rate reductions, or some combination of any of these concessions. When principal is forgiven, the amortized cost basis of the asset is written off against the allowance for credit losses. The amount of the principal forgiveness is deemed to be uncollectible; therefore, that portion of the loan is written off, resulting in a reduction of the amortized cost basis and a corresponding adjustment to the allowance for credit losses. We assess whether a borrower is experiencing financial difficulty based on a variety of factors, including the borrower’s current default on any of its outstanding debt, the probability of a default on any of its debt in the foreseeable future without the modification, the insufficiency of the borrower’s forecasted cash flows to service any of its outstanding debt (including both principal and interest), and the borrower’s inability to access alternative third party financing at an interest rate that would be reflective of current market conditions for a non-troubled debtor. During the year ended December 31, 2024, commercial mortgage loans with an amortized cost of $5 million supporting the funds withheld arrangements with Fortitude Re were granted term extensions. There were no loans that had defaulted during the years ended December 31, 2024 and 2023, that had been previously modified with borrowers experiencing financial difficulties.

Insurance [Abstract]
Reinsurance	8. Reinsurance In the ordinary course of business, our insurance companies purchase both treaty and facultative reinsurance to limit potential losses, provide additional capacity for growth, minimize exposure to significant risks or to facilitate greater diversification of our businesses. In addition, certain of our General Insurance subsidiaries sell reinsurance to other insurance companies. We determine the portion of our ultimate net loss that will be recoverable under our reinsurance contracts by reference to the terms of the reinsurance protection purchased. This determination involves an estimate of incurred but not reported (IBNR) loss. Reinsurance recoverables for contracts which are accounted for as deposits are subject to similar judgments and uncertainties and reported in Deposit accounting assets. Reinsurance assets include the balances due for paid losses and expenses, reserves for losses and expenses reported and outstanding, reserves for IBNR, ceded unearned premiums and ceded future policy benefits for life and accident and health insurance contracts and benefits paid and unpaid. Amounts related to paid and reserved losses and expenses and benefits with respect to these reinsurance agreements are sometimes collateralized. We remain liable to our policyholders regardless of whether our reinsurers meet their obligations under the reinsurance contracts, and as such, we regularly evaluate the financial condition of our reinsurers and monitor concentration of our credit risk. The estimation of the allowance for unrecoverable reinsurance from reinsurers who are unwilling and/or unable to pay amounts due to us requires judgment for which key inputs typically include historical collection rates when amounts due are in dispute or where the reinsurer has suffered a credit event as well as specific reviews of balances in dispute or subject to credit impairment. The allowance for credit losses and disputes on reinsurance assets was $220 million and $206 million at December 31, 2024 and 2023, respectively. Changes in the allowance for credit losses and disputes on reinsurance assets are reflected in Losses and loss adjustment expenses incurred within the Consolidated Statements of Income (Loss). The following table provides supplemental information for loss and benefit reserves, gross and net of ceded reinsurance: At December 31, 2024 2023 (in millions) As Net of As Net of Liability for unpaid losses and loss adjustment expenses $ (69,168) $ (40,032) $ (70,393) $ (39,994) Future policy benefits (1,317) (591) (1,467) (644) Reserve for unearned premiums (17,232) (12,928) (17,375) (13,105) Other policyholder funds (418) (418) (495) (495) Reinsurance assets* 34,166 35,492 * Reinsurance assets excludes (i) allowance for credit losses and disputes of $220 million and $206 million (of which $110 million and $110 million pertains to CECL reserve for Liability for unpaid losses and loss adjustment expenses) for the years ended December 31, 2024 and 2023, respectively, (ii) paid loss recoveries of $4,068 million and $3,819 million for the years ended December 31, 2024 and 2023, respectively, and (iii) policy and contract claims recoverable of $31 million and $27 million for the years ended December 31, 2024 and 2023, respectively. SHORT-DURATION REINSURANCE Short-duration reinsurance is effected under reinsurance treaties and by negotiation on individual risks. Certain of these reinsurance arrangements consist of excess of loss contracts that protect us against losses above stipulated amounts. Ceded premiums are considered prepaid reinsurance premiums and are recognized as a reduction of premiums earned over the contract period in proportion to the protection received. Amounts recoverable from reinsurers on short-duration contracts are estimated in a manner consistent with the claims liabilities associated with the reinsurance and presented as a component of Reinsurance assets. Reinsurance premiums for assumed business are estimated based on information received from brokers, ceding companies and reinsurers. Any subsequent differences arising on such estimates are recorded in the periods in which they are determined. Assumed reinsurance premiums are earned primarily on a pro-rata basis over the terms of the reinsurance contracts and the portion of premiums relating to the unexpired terms of coverage is included in the reserve for unearned premiums. Reinsurance premiums for assumed business are estimated based on information received from brokers, ceding companies and reinsureds. Any subsequent differences arising on such estimates are recorded in the periods in which they are determined. For both ceded and assumed reinsurance, risk transfer requirements must be met for reinsurance accounting to apply. If risk transfer requirements are not met, the contract is accounted for as a deposit, resulting in the recognition of cash flows under the contract through a deposit asset or liability and not as revenue or expense. To meet risk transfer requirements, a reinsurance contract must include both insurance risk, consisting of both underwriting and timing risk, and a reasonable possibility of a significant loss for the assuming entity. Similar risk transfer criteria are used to determine whether directly written insurance contracts should be accounted for as insurance or as a deposit. The following table presents short-duration insurance premiums written and earned: Years Ended December 31, (in millions) 2024 2023 2022 Premiums written: Direct $ 31,743 $ 31,445 $ 32,025 Assumed 3,950 7,951 7,385 Ceded (11,791) (12,190) (12,650) Net $ 23,902 $ 27,206 $ 26,760 Premiums earned: Direct $ 31,208 $ 30,781 $ 32,053 Assumed 3,947 7,050 7,137 Ceded (11,618) (12,267) (12,425) Net $ 23,537 $ 25,564 $ 26,765 Percent of amount assumed to net 16.8 % 27.6 % 26.7 % For the years ended December 31, 2024, 2023 and 2022, reinsurance recoveries, which reduced losses and loss adjustment expenses incurred, amounted to $5.2 billion, $8.1 billion and $7.1 billion, respectively. Retroactive reinsurance agreements are reinsurance agreements under which our reinsurer agrees to reimburse us as a result of past insurable events. For these agreements, the excess of the amounts ultimately collectible under the agreement over the consideration paid is recognized as a deferred gain liability and amortized into income over the settlement period of the ceded reserves. The amount of the deferral is recalculated each period based on loss payments and updated estimates. If the consideration paid exceeds the ultimate losses collectible under the agreement, the net loss on the agreement is recognized in income immediately. Ceded loss reserves under retroactive agreements were $11.5 billion and $12.4 billion, and the deferred gain liability was $725 million and $585 million, as of December 31, 2024 and 2023, respectively. The effect on income from amortization of the deferred gain was $406 million, $82 million and $252 million for the years ended December 31, 2024, 2023 and 2022, respectively. In the first quarter of 2017, we entered into an adverse development reinsurance agreement with National Indemnity Company (NICO), a subsidiary of Berkshire Hathaway Inc., under which we transferred to NICO 80 percent of the reserve risk on substantially all of our U.S. Commercial long-tail exposures for accident years 2015 and prior. Under this agreement, we ceded to NICO 80 percent of the losses on subject business paid on or after January 1, 2016 in excess of $25 billion of net paid losses, up to an aggregate limit of $25 billion. We account for this transaction as retroactive reinsurance. This transaction resulted in a gain, which under U.S. GAAP retroactive reinsurance accounting is deferred and amortized into income over the settlement period. NICO created a collateral trust account as security for their claim payment obligations to us, into which they deposited the consideration paid under the agreement, and Berkshire Hathaway Inc. has provided a parental guarantee to secure NICO’s obligations under the agreement. FORTITUDE RE Fortitude Re is the reinsurer of the majority of AIG’s run-off operations. The reinsurance transactions are structured as modco and loss portfolio transfer arrangements with funds withheld (funds withheld). In modco and funds withheld arrangements, the investments supporting the reinsurance agreements, and which reflect the majority of the consideration that would be paid to the reinsurer for entering into the transaction, are withheld by, and therefore continue to reside on the balance sheet of, the ceding company (i.e., AIG) thereby creating an obligation for the ceding company to pay the reinsurer (i.e., Fortitude Re) at a later date. Additionally, as AIG maintains ownership of these investments, AIG will maintain its existing accounting for these assets (e.g., the changes in fair value of available for sale securities will be recognized within OCI). AIG has established a funds withheld payable to Fortitude Re while simultaneously establishing a reinsurance asset representing reserves for the insurance coverage that Fortitude Re has assumed. The funds withheld payable contains an embedded derivative and changes in fair value of the embedded derivative related to the funds withheld payable are recognized in earnings through Net realized gains (losses). This embedded derivative is considered a total return swap with contractual returns that are attributable to various assets and liabilities associated with these reinsurance agreements. As of December 31, 2024, $3.4 billion of reserves related to business written by multiple wholly-owned AIG subsidiaries, had been ceded to Fortitude Re under these reinsurance transactions. There is a diverse pool of assets supporting the funds withheld arrangements with Fortitude Re. The following summarizes the composition of the pool of assets: December 31, 2024 December 31, 2023 (in millions) Carrying Fair Carrying Fair Corresponding Accounting Policy Fixed maturity securities - available for sale (a) $ 1,918 $ 1,918 $ 2,180 $ 2,180 Fair value through other comprehensive income (loss) Fixed maturity securities - fair value option 721 721 655 655 Fair value through net investment income Commercial mortgage loans 450 437 543 528 Amortized cost Short-term investments 15 15 46 46 Fair value through net investment income Funds withheld investment assets 3,104 3,091 3,424 3,409 Derivative assets, net (b) 1 1 — — Fair value through net realized gains (losses) Other (c) 115 115 118 118 Amortized cost Total $ 3,220 $ 3,207 $ 3,542 $ 3,527 (a) The change in the net unrealized gains (losses) on available for sale securities related to the Fortitude Re funds withheld assets was $(35) million ($(28) million after-tax) and $116 million ($92 million after-tax), respectively for the years ended December 31, 2024 and 2023. (b) The derivative assets and liabilities have been presented net of cash collateral. The derivative assets and liabilities supporting the Fortitude Re funds withheld arrangements had a fair market value of $9 million and $2 million, respectively, as of December 31, 2024. The derivative assets and liabilities supporting the Fortitude Re funds withheld arrangements had a fair market value of $1 million and $28 million, respectively, as of December 31, 2023. These derivative assets and liabilities are fully collateralized either by cash or securities. (c) Primarily comprised of Cash and Accrued investment income. The impact of the funds withheld arrangements with Fortitude Re was as follows: Years Ended December 31, (in millions) 2024 2023 2022 Net investment income - Fortitude Re funds withheld assets $ 144 $ 180 $ 53 Net realized gains (losses) on Fortitude Re funds withheld assets: Net realized losses - Fortitude Re funds withheld assets (39) (71) (99) Net realized gains (losses) - Fortitude Re funds withheld embedded derivative (75) (273) 1,133 Net realized gains (losses) on Fortitude Re funds withheld assets (114) (344) 1,034 Income (loss) from continuing operations before income tax expense (benefit) 30 (164) 1,087 Income tax expense (benefit) (a) 6 (34) 228 Net income (loss) 24 (130) 859 Change in unrealized appreciation (depreciation) on available for sale securities (a) (28) 92 (848) Comprehensive income (loss) $ (4) $ (38) $ 11 (a) The income tax expense (benefit) and the tax impact in Accumulated other comprehensive income (loss) (AOCI) was computed using AIG’s U.S. statutory tax rate of 21 percent. Various assets supporting the Fortitude Re funds withheld arrangements are reported at amortized cost, and as such, changes in the fair value of these assets are not reflected in the financial statements. However, changes in the fair value of these assets are included in the embedded derivative in the Fortitude Re funds withheld arrangement and the appreciation (depreciation) of the asset is the primary driver of the comprehensive income (loss) reflected above. Reinsurance Security Our third-party reinsurance arrangements do not relieve us from our direct obligations to our beneficiaries. Thus, a credit exposure exists with respect to both short-duration and long-duration reinsurance ceded to the extent that any reinsurer fails to meet the obligations assumed under any reinsurance agreement. We hold substantial collateral as security under related reinsurance agreements in the form of funds, securities, and/or letters of credit. A provision has been recorded for estimated unrecoverable reinsurance. In light of collateral held, we believe that no exposure to a single reinsurer represents an inappropriate concentration of credit risk to AIG. Gross reinsurance assets due from reinsurers exceeding 5 percent of our total reinsurance assets were approximately $15.2 billion and $16.5 billion at December 31, 2024 and 2023, respectively, of which approximately $2.1 billion and $2.3 billion at December 31, 2024 and 2023, respectively, was not secured by collateral. REINSURANCE – CREDIT LOSSES The estimation of reinsurance recoverables involves a significant amount of judgment, particularly for latent exposures, such as asbestos, due to their long-tail nature. We assess the collectability of reinsurance recoverable balances in each reporting period, through either historical trends of disputes and credit events or financial analysis of the credit quality of the reinsurer. We record adjustments to reflect the results of these assessments through an allowance for credit losses and disputes on uncollectible reinsurance that reduces the carrying amount of reinsurance and deposit accounting assets on the consolidated balance sheets (collectively, reinsurance recoverables). This estimate requires significant judgment for which key considerations include: • paid and unpaid amounts recoverable; • whether the balance is in dispute or subject to legal collection; • the relative financial health of the reinsurer as classified by the Obligor Risk Ratings (ORRs) we assign to each reinsurer based upon our financial reviews; reinsurers that are financially troubled (i.e., in run-off, have voluntarily or involuntarily been placed in receivership, are insolvent, are in the process of liquidation or otherwise subject to formal or informal regulatory restriction) are assigned ORRs that will generate a significant allowance; and • whether collateral and collateral arrangements exist. An estimate of the reinsurance recoverable's lifetime expected credit losses is established utilizing a probability of default and loss given default method, which reflects the reinsurer’s ORR. The allowance for credit losses excludes disputed amounts. An allowance for disputes is established for a reinsurance recoverable using the losses incurred model for contingencies. The total reinsurance recoverables as of December 31, 2024 were $40.5 billion. As of that date, utilizing AIG’s ORRs, (i) approximately 83 percent of the reinsurance recoverables were investment grade; (ii) approximately 15 percent of the reinsurance recoverables were non-investment grade and (iii) approximately 2 percent of the reinsurance recoverables related to entities that were not rated by AIG. The total reinsurance recoverables as of December 31, 2023 were $41.4 billion. As of that date, utilizing AIG’s ORRs, (i) approximately 83 percent of the reinsurance recoverables were investment grade; (ii) approximately 15 percent of the reinsurance recoverables were non-investment grade; (iii) approximately 2 percent of the reinsurance recoverables related to entities that were not rated by AIG. As of December 31, 2024 and December 31, 2023, approximately 81 percent and 85 percent, respectively, of our non-investment grade reinsurance exposure related to captive insurers. These arrangements are typically collateralized by letters of credit, funds withheld or trust agreements. Reinsurance Recoverable Allowance The following table presents a rollforward of the reinsurance recoverable allowance: Years Ended December 31, (in millions) 2024 2023 2022 Balance, beginning of period $ 255 $ 260 $ 281 Addition to (release of) allowance for expected credit losses and disputes, net 11 (5) (22) Write-offs charged against the allowance for credit losses and disputes (1) — (5) Recoveries of amounts previously written off — — 2 Other changes 4 — 4 Balance, end of year $ 269 $ 255 $ 260 Past-Due Status We consider a reinsurance asset to be past due when it is 90 days past due. The allowance for credit losses is estimated excluding disputed amounts. An allowance for disputes is established using the losses incurred method for contingencies. Past due balances on claims that are not in dispute were not material for any of the periods presented.

Deferred Policy Acquisition Cos

Deferred Costs, Capitalized, Prepaid, and Other Assets Disclosure [Abstract]
Deferred Policy Acquisition Costs	9. Deferred Policy Acquisition Costs Deferred Policy Acquisition Costs (DAC) represent those costs that are incremental and directly related to the successful acquisition of new or renewal of existing insurance contracts. We defer incremental costs that result directly from, and are essential to, the acquisition or renewal of an insurance contract. Such DAC generally include agent or broker commissions and bonuses, premium taxes, and medical and inspection fees that would not have been incurred if the insurance contract had not been acquired or renewed. Each cost is analyzed to assess whether it is fully deferrable. We partially defer costs, including certain commissions, when we do not believe that the entire cost is directly related to the acquisition or renewal of insurance contracts. Commissions that are not deferred to DAC are recorded in General operating and other expenses in the Consolidated Statements of Income (Loss). We also defer a portion of employee total compensation and payroll-related fringe benefits directly related to time spent performing specific acquisition or renewal activities, including costs associated with the time spent on underwriting, policy issuance and processing, and sales force contract selling. The amounts deferred are derived based on successful efforts for each distribution channel and/or cost center from which the cost originates. Policy acquisition costs are deferred and amortized over the period in which the related premiums written are earned, generally 12 months. DAC is grouped consistent with the manner in which the insurance contracts are acquired, serviced and measured for profitability and is reviewed for recoverability based on the profitability of the underlying insurance contracts. Investment income is anticipated in assessing the recoverability of DAC. We assess the recoverability of DAC on an annual basis or more frequently if circumstances indicate an impairment may have occurred. This assessment is performed by comparing recorded net unearned premiums and anticipated investment income on in-force business to the sum of expected losses and loss adjustment expenses incurred, unamortized DAC and maintenance costs. If the sum of these costs exceeds the amount of recorded net unearned premiums and anticipated investment income, the excess is recognized as an offset against the asset established for DAC. This offset is referred to as a premium deficiency charge. Increases in expected losses and loss adjustment expenses incurred can have a significant impact on the likelihood and amount of a premium deficiency charge. The following table presents a rollforward of DAC: Years Ended December 31, (in millions) 2024 2023 2022 Balance, beginning of year $ 2,117 $ 2,343 $ 2,473 Capitalization 3,519 4,157 3,732 Amortization expense (3,425) (3,771) (3,545) Other, including foreign exchange (146) (34) (317) Dispositions* — (578) — Balance, end of year $ 2,065 $ 2,117 $ 2,343 * Includes amounts related to the sale of Validus Re through the date of disposition.

Variable Interest Entities

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	10. Variable Interest Entities A variable interest entity (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 significant decisions relating to the entity’s operations through voting rights or do not substantively participate in the gains and losses of the entity. Consolidation of a VIE by its primary beneficiary is not based on majority voting interest, but is based on other criteria discussed below. We enter into various arrangements with VIEs in the normal course of business and consolidate the VIEs when we determine we are the primary beneficiary. This analysis includes a review of the VIE’s capital structure, related contractual relationships and terms, nature of the VIE’s operations and purpose, nature of the VIE’s interests issued and our involvement with the entity. When assessing the need to consolidate a VIE, we evaluate the design of the VIE as well as the related risks to which the entity was designed to expose the variable interest holders. The primary beneficiary is the entity that has both (i) the power to direct the activities of the VIE that most significantly affect the entity’s economic performance and (ii) the obligation to absorb losses or the right to receive benefits that could be potentially significant to the VIE. While also considering these factors, the consolidation conclusion depends on the breadth of our decision-making ability and our ability to influence activities that significantly affect the economic performance of the VIE. BALANCE SHEET CLASSIFICATION AND EXPOSURE TO LOSS Creditors or beneficial interest holders of VIEs for which AIG is the primary beneficiary generally have recourse only to the assets and cash flows of the VIEs and do not have recourse to AIG, except in limited circumstances when AIG has provided a guarantee to the VIE’s interest holders. The following table presents the total assets and total liabilities associated with our variable interests in consolidated VIEs, as classified in the Consolidated Balance Sheets: At December 31, 2024, there were no assets and liabilities associated with our variable interests in consolidated VIEs. (in millions) December 31, 2023 Assets: Bonds available for sale $ 72 Mortgage and other loans receivable 122 Short-term investments 5 Accrued investment income 2 Other assets 1 Total* $ 202 Liabilities: Debt of consolidated investment entities $ 38 Total $ 38 * The assets of each VIE can be used only to settle specific obligations of that VIE. We calculate our maximum exposure to loss to be (i) the amount invested in the debt or equity of the VIE, (ii) the notional amount of VIE assets or liabilities where we have also provided credit protection to the VIE with the VIE as the referenced obligation, and (iii) other commitments and guarantees to the VIE. The following table presents total assets of unconsolidated VIEs in which we hold a variable interest, as well as our maximum exposure to loss associated with these VIEs: Maximum Exposure to Loss (in millions) Total VIE On-Balance (c) Off-Balance Total December 31, 2024 Real estate and investment entities (a) $ 367,661 $ 2,723 $ 839 (d) $ 3,562 Other (b) 4,639 255 754 (e) 1,009 Total $ 372,300 $ 2,978 $ 1,593 $ 4,571 December 31, 2023 Real estate and investment entities (a) $ 355,003 $ 4,107 $ 1,492 (d) $ 5,599 Other (b) 1,027 — 748 (e) 748 Total $ 356,030 $ 4,107 $ 2,240 $ 6,347 (a) Comprised primarily of hedge funds and private equity funds. (b) At December 31, 2024 and 2023, excludes approximately $1,925 million and $1,971 million, respectively, of VIE assets related to AIGFP and its consolidated subsidiaries, with maximum off-balance sheet exposure to loss of $1,894 million and $1,941 million, respectively. For additional information, see Note 1. (c) At December 31, 2024 and 2023, $2.9 billion and $4.1 billion, respectively, of our total unconsolidated VIE assets were recorded as Other invested assets. (d) These amounts represent our unfunded commitments to invest in private equity funds. (e) These amounts represent our estimate of the maximum exposure to loss under certain insurance policies issued to VIEs if a hypothetical loss occurred to the extent of the full amount of the insured value. Our insurance policies cover defined risks and our estimate of liability is included in our insurance reserves on the balance sheet. REAL ESTATE AND INVESTMENT ENTITIES Through our insurance operations and AIG Global Real Estate Investment Corp., we are an investor in various real estate investment entities, some of which are VIEs. These investments are typically with unaffiliated third-party developers via a partnership or limited liability company structure. The VIEs’ activities consist of the development or redevelopment of commercial, industrial and residential real estate. Our involvement varies from being a passive equity investor or finance provider to actively managing the activities of the VIEs. Our insurance operations participate as passive investors in the equity issued by certain third-party-managed hedge and private equity funds that are VIEs. Our insurance operations typically are not involved in the design or establishment of these VIEs, nor do they actively participate in the management of the VIEs. RMBS, CMBS, OTHER ABS AND CLOS

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedge Accounting	11. Derivatives and Hedge Accounting We use derivatives and other financial instruments as part of our financial risk management programs and as part of our investment operations. Interest rate derivatives (such as interest rate swaps) are used to manage interest rate risk associated with embedded derivatives contained in insurance contract liabilities, fixed maturity securities, outstanding medium- and long-term notes as well as other interest rate sensitive assets and liabilities. Foreign exchange derivatives (principally foreign exchange forwards and swaps) are used to economically mitigate risk associated with non-U.S. dollar denominated debt, net capital exposures, foreign currency transactions, and foreign denominated investments. Equity derivatives are used to economically mitigate financial risk associated with embedded derivatives. We use credit derivatives to manage our credit exposures. The derivatives are effective economic hedges of the exposures that they are meant to offset. In addition to hedging activities, we also enter into derivative contracts with respect to investment operations, which may include, among other things, CDSs, total return swaps and purchases of investments with embedded derivatives, such as equity-linked notes and convertible bonds. Interest rate, currency, equity swaps, credit contracts, swaptions, options and forward transactions are accounted for as derivatives, recorded on a trade-date basis and carried at fair value. Unrealized gains and losses are reflected in income, when appropriate. Aggregate asset or liability positions are netted on the Consolidated Balance Sheets only to the extent permitted by qualifying master netting arrangements in place with each respective counterparty. Cash collateral posted with counterparties in conjunction with transactions supported by qualifying master netting arrangements is reported as a reduction of the corresponding net derivative liability, while cash collateral received in conjunction with transactions supported by qualifying master netting arrangements is reported as a reduction of the corresponding net derivative asset. Derivatives, with the exception of embedded derivatives, are reported at fair value in the Consolidated Balance Sheets in Other assets and Other liabilities. Embedded derivatives are generally presented with the host contract in the Consolidated Balance Sheets. A bifurcated embedded derivative is measured at fair value and accounted for in the same manner as a free standing derivative contract. The corresponding host contract is accounted for according to the accounting guidance applicable for that instrument. For additional information on embedded derivatives, see Notes 5 and 13. The following table presents the notional amounts of our derivatives and the fair value of derivative assets and liabilities in the Consolidated Balance Sheets: December 31, 2024 December 31, 2023 Gross Derivative Assets Gross Derivative Liabilities Gross Derivative Assets Gross Derivative Liabilities (in millions) Notional Fair Notional Fair Notional Fair Notional Fair Derivatives designated as hedging instruments: (a) Foreign exchange contracts $ 879 $ 66 $ 906 $ 109 $ 933 $ 58 $ 1,296 $ 164 Derivatives not designated as hedging instruments: (a) Interest rate contracts 841 277 913 304 14,657 741 1,165 352 Foreign exchange contracts 3,095 230 1,707 158 4,019 393 8,008 400 Equity contracts 29 20 29 20 36,045 66 — — Credit contracts (b) 52 31 147 31 1,804 33 504 36 Other contracts (c) — — — — 2,131 1 — — Total derivatives, gross $ 4,896 $ 624 $ 3,702 $ 622 $ 59,589 $ 1,292 $ 10,973 $ 952 Counterparty netting (d) (270) (270) (450) (450) Cash collateral (e) (304) (201) (711) (249) Total derivatives on Consolidated Balance Sheets (f) $ 50 $ 151 $ 131 $ 253 (a) Fair value amounts are shown before the effects of counterparty netting adjustments and offsetting cash collateral. (b) As of December 31, 2024 and 2023, included CDSs on super senior multi-sector CLO with a net notional amount of $48 million and $50 million (fair value liability of $30 million and $32 million, respectively). The net notional amount represents the maximum exposure to loss on the portfolio. (c) Consists primarily of stable value wraps and contracts with multiple underlying exposures. (d) Represents netting of derivative exposures covered by a qualifying master netting agreement. (e) Represents cash collateral posted and received that is eligible for netting. (f) Freestanding derivatives only, excludes embedded derivative s. Derivative instrument assets and liabilities are recorded in Other assets and Other liabilities, respectively. Fair value of assets related to bifurcated embedded derivatives was $3.2 billion at December 31, 2024 and $3.4 billion at December 31, 2023. Fair value of liabilities related to bifurcated embedded derivatives was zero at both December 31, 2024 and 2023. A bifurcated embedded derivative is generally presented with the host contract in the Consolidated Balance Sheets. Embedded derivatives are primarily related to the funds withheld arrangement with Fortitude Re. For additional information, see Note 8. COLLATERAL We engage in derivative transactions that are not subject to a clearing requirement directly with unaffiliated third parties, in most cases, under International Swaps and Derivatives Association, Inc. (ISDA) Master Agreements. Many of the ISDA Master Agreements also include Credit Support Annex provisions, which provide for collateral postings that may vary at various ratings and threshold levels. We attempt to reduce our risk with certain counterparties by entering into agreements that enable collateral to be obtained from a counterparty on an upfront or contingent basis. We minimize the risk that counterparties might be unable to fulfill their contractual obligations by monitoring counterparty credit exposure and collateral value and generally requiring additional collateral to be posted upon the occurrence of certain events or circumstances. In addition, certain derivative transactions have provisions that require collateral to be posted by us upon a downgrade of our long-term debt ratings or give the counterparty the right to terminate the transaction. In the case of some of the derivative transactions, upon a downgrade of our long-term debt ratings, as an alternative to posting collateral and subject to certain conditions, we may assign the transaction to an obligor with higher debt ratings or arrange for a substitute guarantee of our obligations by an obligor with higher debt ratings or take other similar action. The actual amount of collateral required to be posted to counterparties in the event of such downgrades, or the aggregate amount of payments that we could be required to make, depends on market conditions, the fair value of outstanding affected transactions and other factors prevailing at and after the time of the downgrade. Collateral posted by us to third parties for derivative transactions was $601 million and $593 million at December 31, 2024 and 2023, respectively. In the case of collateral posted under derivative transactions that are not subject to clearing, this collateral can generally be repledged or resold by the counterparties. Collateral provided to us from third parties for derivative transactions was $595 million and $856 million at December 31, 2024 and 2023, respectively. In the case of collateral provided to us under derivative transactions that are not subject to clearing, we generally can repledge or resell collateral. OFFSETTING We have elected to present all derivative receivables and derivative payables, and the related cash collateral received and paid, on a net basis on our Consolidated Balance Sheets when a legally enforceable ISDA Master Agreement exists between us and our derivative counterparty. An ISDA Master Agreement is an agreement governing multiple derivative transactions between two counterparties. The ISDA Master Agreement generally provides for the net settlement of all, or a specified group, of these derivative transactions, as well as transferred collateral, through a single payment, and in a single currency, as applicable. The net settlement provisions apply in the event of a default on, or affecting any, one derivative transaction or a termination event affecting all, or a specified group of, derivative transactions governed by the ISDA Master Agreement. HEDGE ACCOUNTING We designated certain derivatives entered into with third parties as fair value hedges of available for sale investment securities held by our insurance subsidiaries. The fair value hedges include foreign currency forwards and cross currency swaps designated as hedges of the change in fair value of foreign currency denominated available for sale securities attributable to changes in foreign exchange rates. We use foreign currency denominated debt and cross-currency swaps as hedging instruments in net investment hedge relationships to mitigate the foreign exchange risk associated with our non-U.S. dollar functional currency foreign subsidiaries. For net investment hedge relationships where issued debt is used as a hedging instrument, we assess the hedge effectiveness and measure the amount of ineffectiveness based on changes in spot rates. For net investment hedge relationships that use derivatives as hedging instruments, we assess hedge effectiveness and measure hedge ineffectiveness using changes in forward rates. For the years ended December 31, 2024, 2023 and 2022, we recognized gains (losses) of $86 million, $(42) million and $305 million, respectively, included in Change in foreign currency translation adjustments in OCI related to the net investment hedge relationships.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	12. Goodwill and Other Intangible Assets Goodwill represents the future economic benefits arising from assets acquired in a business combination that are not individually identified and separately recognized. Goodwill is tested for impairment at the reporting unit level, which is defined as a segment or one level below, and the test is performed annually, or more frequently if circumstances indicate an impairment may have occurred. At December 31, 2024, goodwill is reported within North America Commercial, International Commercial and Global Personal segments, and within Other Operations. When a business is transferred from one reporting unit to another, goodwill from the original reporting unit is allocated among reporting units based on the fair value of business transferred, relative to business retained by a reporting unit. The impairment assessment involves an option to first assess qualitative factors to determine whether events or circumstances exist that lead to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the qualitative assessment is not performed, or after assessing the totality of the events or circumstances, we determine it is more likely than not that the fair value of a reporting unit is less than its carrying amount, a quantitative assessment for potential impairment is performed. If the qualitative test is not performed or if the test indicates a potential impairment is present, we estimate the fair value of each reporting unit and compare the estimated fair value with the carrying amount of the reporting unit, including allocated goodwill. The estimate of a reporting unit’s fair value involves management judgment and is based on one or a combination of approaches including discounted expected future cash flows, market-based earnings multiples of the unit’s peer companies, external appraisals or, in the case of reporting units being considered for sale, third-party indications of fair value, if available. We consider one or more of these estimates when determining the fair value of a reporting unit to be used in the impairment test. If the estimated fair value of a reporting unit exceeds its carrying amount, goodwill is not impaired. If the carrying value of a reporting unit exceeds its estimated fair value, goodwill associated with that reporting unit potentially is impaired. The amount of impairment, if any, is measured as the excess of a reporting unit’s carrying amount over its fair value not to exceed the total amount of goodwill allocated to that reporting unit and recognized in income. The following table presents the changes in goodwill: General Insurance (in millions) North America International Global Other Total Balance at January 1, 2023: Goodwill - gross $ 4,654 $ 1,989 $ 499 $ 19 $ 7,161 Accumulated impairments (2,216) (947) (237) (10) (3,410) Net goodwill 2,438 1,042 262 9 3,751 Increase (decrease) due to: Dispositions* (369) — — — (369) Other — 39 3 (2) 40 Balance at December 31, 2023: Goodwill - gross 4,285 2,028 502 17 6,832 Accumulated impairments (2,216) (947) (237) (10) (3,410) Net goodwill 2,069 1,081 265 7 3,422 Increase (decrease) due to: Dispositions — — (22) — (22) Other — (25) (2) — (27) Balance at December 31, 2024: Goodwill - gross 4,285 2,003 478 17 6,783 Accumulated impairments (2,216) (947) (237) (10) (3,410) Net goodwill $ 2,069 $ 1,056 $ 241 $ 7 $ 3,373 * Primarily represents amounts related to the sale of Validus Re through the date of disposition. Indefinite lived intangible assets are not subject to amortization. Indefinite lived intangible assets primarily include Lloyd’s syndicate capacity and brand names. Finite lived intangible assets are amortized over their useful lives. Finite lived intangible assets primarily include distribution networks and are recorded net of accumulated amortization. The Company tests indefinite lived intangible assets for impairment on an annual basis or whenever events or circumstances suggest that the carrying value of an intangible asset may exceed the sum of the undiscounted cash flows expected to result from its use and eventual disposition. If this condition exists and the carrying value of an intangible asset exceeds its fair value, the excess is recognized as an impairment and is recorded as a charge against net income (loss).

Insurance [Abstract]
Insurance Liabilities	13. Insurance Liabilities LIABILITY FOR UNPAID LOSSES AND LOSS ADJUSTMENT EXPENSES (LOSS RESERVES) Loss reserves represent the accumulation of estimates of unpaid claims, including estimates for claims incurred but not reported and loss adjustment expenses, less applicable discount. We regularly review and update the methods used to determine loss reserve estimates. Any adjustments resulting from this review are reflected currently in pre-tax income, except to the extent such adjustment impacts a deferred gain under a retroactive reinsurance agreement, in which case the ceded portion would be amortized into pre-tax income in subsequent periods. Because these estimates are subject to the outcome of future events, changes in estimates are common given that loss trends vary and time is often required for changes in trends to be recognized and confirmed. Reserve changes that increase previous estimates of ultimate cost are referred to as unfavorable or adverse development or reserve strengthening. Reserve changes that decrease previous estimates of ultimate cost are referred to as favorable development or reserve releases. Our gross loss reserves before reinsurance and discount are net of contractual deductible recoverable amounts due from policyholders of approximately $12.1 billion at both December 31, 2024 and 2023. These recoverable amounts are related to certain policies with high deductibles (in excess of high dollar amounts retained by the insured through self-insured retentions, deductibles, retrospective programs, or captive arrangements, each referred to generically as “deductibles”), primarily for U.S. Commercial casualty business. With respect to the deductible portion of the claim, we manage and pay the entire claim on behalf of the insured and are reimbursed by the insured for the deductible portion of the claim. Thus, these recoverable amounts represent a credit exposure to us. At December 31, 2024 and 2023 we held collateral of approximately $8.6 billion and $8.7 billion, respectively, for these deductible recoverable amounts, consisting primarily of letters of credit and funded trust agreements. Allowance for credit losses for the unsecured portion of these recoverable amounts was $14 million at both December 31, 2024 and 2023. The following table presents the rollforward of activity in loss reserves: Years Ended December 31, (in millions) 2024 2023 2022 Liability for unpaid loss and loss adjustment expenses, beginning of year $ 70,393 $ 75,167 $ 79,026 Reinsurance recoverable (30,289) (32,102) (35,213) Net Liability for unpaid loss and loss adjustment expenses, beginning of year 40,104 43,065 43,813 Losses and loss adjustment expenses incurred: Current year 14,363 15,100 16,434 Prior years, excluding discount and amortization of deferred gain 254 (392) (530) Prior years, discount charge (benefit) 354 307 (605) Prior years, amortization of deferred gain on retroactive reinsurance (a) (404) (81) (252) Total losses and loss adjustment expenses incurred 14,567 14,934 15,047 Losses and loss adjustment expenses paid: Current year (3,694) (3,836) (4,011) Prior years (9,849) (11,868) (11,066) Total losses and loss adjustment expenses paid (13,543) (15,704) (15,077) Other changes: Foreign exchange effect (996) 606 (1,463) Losses and loss adjustment expenses recognized within gain on divestitures — 569 — Retroactive reinsurance adjustment (net of discount) (b) 15 158 745 Dispositions (c) (5) (3,505) — Reclassified to held for sale, net of reinsurance recoverables — (19) — Total other changes (986) (2,191) (718) Liability for unpaid loss and loss adjustment expenses, end of year: Net liability for unpaid losses and loss adjustment expenses 40,142 40,104 43,065 Reinsurance recoverable 29,026 30,289 32,102 Total $ 69,168 $ 70,393 $ 75,167 (a) Includes $82 million, $33 million and $63 million for the retroactive reinsurance agreement with NICO covering U.S. asbestos exposures for the years ended December 31, 2024, 2023 and 2022, respectively. (b) Includes benefit (charge) from change in discount on retroactive reinsurance in the amount of $168 million, $150 million and $(301) million for the years ended December 31, 2024, 2023 and 2022, respectively. (c) Includes amounts related to the sale of Validus Re through the date of disposition. The following table presents the reconciliation of the net liability for unpaid losses and loss adjustment expenses in the following tables to Loss Reserves in the Consolidated Balance Sheets for the year ended December 31, 2024: (in millions) Net liability for unpaid Reinsurance recoverable on Gross liability U.S. Workers' Compensation (before discount) $ 3,468 $ 4,852 $ 8,320 U.S. Excess Casualty 3,208 3,139 6,347 U.S. Other Casualty 4,387 3,416 7,803 U.S. Financial Lines 5,422 1,614 7,036 U.S. Property and Special Risks 4,297 1,233 5,530 U.S. Personal Insurance 836 2,048 2,884 UK/Europe Casualty and Financial lines 7,280 1,952 9,232 UK/Europe Property and Special Risks 2,355 1,761 4,116 UK/Europe and Japan Personal Insurance 1,269 670 1,939 Total $ 32,522 $ 20,685 $ 53,207 Reconciling Items Discount on workers' compensation lines (2,111) Other product lines* 15,384 Unallocated loss adjustment expenses 2,688 Total Loss Reserves $ 69,168 * Reinsurance recoverable for other product lines of $8.4 billion resulted in a net liability for unpaid losses and loss adjustment expenses of $7.0 billion for the year ended December 31, 2024. Prior Year Development In the sections below, we provide details by coverage group regarding incurred losses, reserve balances and prior year development. The first table below shows prior year development by coverage group, the first two columns of which will again be presented in the coverage group sections that follow. After this table we describe historical drivers of prior year development as well as actuarial methods and relevant terminology. The following coverage group sections present the undiscounted incurred losses and allocated loss adjustment expenses by accident year on a net basis after reinsurance, with separate presentation of the adverse development cover where applicable, excluding related amortization of the deferred gain. Each section also contains a description of the business included in that section. Finally, we show a table of claims payout patterns by coverage. In 2017, we entered into adverse development reinsurance agreement (ADC) cessions with NICO under which we transferred to NICO 80 percent of the reserve risk on substantially all of our U.S. Commercial long-tail exposures for accident years 2015 and prior. The following table presents the reconciliation of net prior year development before the ADC cessions from the tables below to the net prior year development after ADC cessions and amortization of deferred gain for the year ended December 31, 2024: (in millions) Prior Year Prior Year (a) Re-Attribution (b) Amortization Prior Year U.S. Workers' Compensation $ (273) $ (205) $ (14) $ (42) $ (261) U.S. Excess Casualty 545 238 22 (32) 228 U.S. Other Casualty 12 44 (38) (31) (25) U.S. Financial Lines 51 (40) 20 (23) (43) U.S. Property and Special Risks (44) 4 11 (7) 8 U.S. Personal Insurance (23) (25) (1) (1) (27) UK/Europe Casualty and Financial lines 170 170 — — 170 UK/Europe Property and Special Risks (35) (35) — — (35) UK/Europe and Japan Personal Insurance (47) (47) — — (47) Other Operations 1 1 — — 1 Other product lines (299) (336) — — (336) Subtotal, adjusted pre-tax basis $ 58 $ (231) $ — $ (136) $ (367) Businesses in run-off 196 111 — — 111 Subtotal $ 254 $ (120) $ — $ (136) $ (256) Remove impact of Retroactive Reinsurance Amortization of deferred gain at inception 136 Prior year development ceded under the Asbestos LPT 85 Prior year development ceded under the ADC 289 Total, prior years, excluding discount and amortization of deferred gain $ 254 (a) Change in net ultimate loss and loss adjustment expenses excludes the portion of prior year development we have ceded under the Asbestos Loss Portfolio Transfer (LPT) and the ADC, both of which are provided by NICO and are considered retroactive reinsurance under U.S. GAAP. (b) Reattribution of the ADC recovery takes place annually as we model the future payments on the subject reserves. ADC recoverables are then reallocated by line based on payments expected to be made. During 2024, we recognized unfavorable prior year loss reserve development of $254 million excluding discount and amortization of deferred gain. The development was primarily driven by: • Favorable development on U.S. Workers’ Compensation of $273 million, net of external reinsurance but before ADC cessions reflecting continued favorable loss experience; • Unfavorable development on U.S. Excess Casualty of $545 million, net of external reinsurance but before ADC cessions, driven by a large settlement of a legacy mass tort claim with the gross loss in accident years covered under the ADC and increased reserves related to claims emergence; • Unfavorable development on U.S Other Casualty of $12 million, net of external reinsurance but before ADC cessions, reflecting unfavorable development on Commercial Auto and Wholesale Primary General Liability, partially offset by favorability across numerous Casualty reserving classes; • Unfavorable development in U.S. Financial Lines of $51 million, net of external reinsurance but before ADC cessions, due to unfavorable development in M&A and High Excess classes, offset by favorable experience across most reserving classes; • Favorable development on U.S Property and Special Risks of $44 million, net of external reinsurance but before ADC cessions, reflecting favorable loss experience in Retail and Wholesale Property, offset by development on prior year catastrophes; • Favorable development in U.S. Personal Insurance of $23 million driven by favorable development on prior year catastrophes across several events primarily in the 2019-2023 accident years; • Unfavorable development in UK/Europe Casualty and Financial Lines of $170 million driven by unfavorable development in UK Financial Lines partially offset by favorable development in EMEA Financial Lines, and unfavorable development in European Excess Casualty driven by claim-specific emergence on accident year 2016; • Favorable development on UK/Europe Property and Special Risks of $35 million reflecting favorable development across most segments and geographies; • Favorable development on UK/Europe and Japan Personal Insurance of $47 million primarily driven by Japan A&H and Auto, partially offset by unfavorable Personal Auto in EMEA; • Favorable development of $299 million in total on other product lines, net of external reinsurance but before ADC cessions, primarily driven by Global Specialty which saw favorable development across multiple lines; and • Unfavorable development on Businesses in run-off of $196 million, net of external reinsurance but before ADC cessions, is primarily attributed to Asbestos development of $85 million, which is entirely ceded under the LPT, and development on the Blackboard insurance portfolio of $112 million due to increased reported loss activity in general liability. During 2023, we recognized favorable prior year loss reserve development of $392 million excluding discount and amortization of deferred gain. The development was primarily driven by: • Favorable development on U.S. Workers’ Compensation of $267 million, net of external reinsurance but before ADC cessions due to a continuation of favorable loss cost trends in guaranteed cost and excess segments across most accident years; • Favorable development on U.S. Excess Casualty of $32 million, net of external reinsurance but before ADC cessions, driven by favorable development on the Excess Construction Runoff Portfolio; • Favorable development on U.S Other Casualty of $133 million, net of external reinsurance but before ADC cessions, largely driven by favorable experience in construction defect and construction wraps as well as guaranteed cost auto and general liability; • Unfavorable development in U.S. Financial Lines of $94 million, net of external reinsurance but before ADC cessions, due to unfavorable development on High Attaching Excess Directors and Officers (D&O), M&A, Primary National D&O, Cyber data privacy claims, and Architects & Engineers, partially offset by favorable development on Primary Private Not for Profit D&O and Financial Institutions D&O; • Favorable development on U.S Property and Special Risks of $10 million, net of external reinsurance but before ADC cessions, reflecting favorable development on prior year catastrophes in the 2017-2021 accident years, offset by adverse development on prior year catastrophes in the 2022 accident year; • Favorable development in U.S. Personal Insurance of $64 million driven by favorable development on prior year catastrophes across several events primarily in the 2017-2020 accident years; • Unfavorable development in UK/Europe Casualty and Financial Lines of $165 million due to unfavorable development in auto liability in Europe and UK and in UK D&O and Commercial Professional Indemnity business, partially offset by favorable development in Financial Institutions Professional Indemnity and D&O in Europe and UK and Cyber and Commercial Professional Indemnity in Europe; • Unfavorable development on UK/Europe Property and Special Risks of $81 million driven by unfavorable development on prior year catastrophes; • Favorable development on UK/Europe and Japan Personal Insurance of $57 million driven by favorable development in Japan personal auto and A&H business; and • Favorable development of $162 million in total on other product lines, net of external reinsurance but before ADC cessions, driven by favorable development in global specialty and financial lines in Canada and other International regions. During 2022, we recognized favorable prior year loss reserve development of $530 million excluding discount and amortization of deferred gain. The development was primarily driven by: • Favorable development on U.S. Workers’ Compensation of $644 million, net of external reinsurance but before ADC cessions due to continued favorable frequency and severity trends across most accident years particularly for excess and guaranteed cost US Workers Compensation segments; • Favorable development on U.S. Excess Casualty of $116 million, net of external reinsurance but before ADC cessions, driven by lead and mid-excess Retail Excess Casualty; • Favorable development on U.S Other Casualty of $149 million, net of external reinsurance but before ADC cessions, largely driven by favorable experience in Commercial Auto, General Liability and Construction Wraps; • Unfavorable development in U.S. Financial Lines of $939 million, net of external reinsurance but before ADC cessions, due to higher severity trends particularly in Excess & Primary D&O and Excess & Financial Institutions Errors and Omissions (E&O). This was partially offset by favorable development in Employment Practices Liability Insurance (EPLI); • Favorable development in U.S. Property and Special Risks of $81 million driven by more favorable crop experience than anticipated; • Unfavorable development in UK/Europe Casualty and Financial Lines of $82 million due to unfavorable experience in UK Financial Lines in M&A, Commercial PI and Commercial D&O as well as unfavorable Casualty experience due to large loss activity in the UK, European Excess Casualty, and French Auto experience; • Favorable development on UK/Europe Property and Special Risks of $153 million driven by Global Specialty, primarily from accident years 2020 and 2021. This favorable experience was seen in each product line and in every region; • Favorable development on UK/Europe and Japan Personal Insurance of $111 million driven by Japan Auto and A&H business with additional favorable experience in UK and Europe; and • Favorable development of $264 million in total on other product lines, net of external reinsurance but before ADC cessions, driven by runoff construction business and favorable results from our Canadian business across most products. Our analyses and conclusions about prior year reserves also help inform our judgments about the current accident year loss and loss adjustment expense ratios we selected. Loss Development Information The following is information about incurred and paid loss developments as of December 31, 2024, net of reinsurance. The cumulative number of reported claims, the total of IBNR liabilities and expected development on reported loss included within the net incurred loss amounts are presented in the following section. Reserving Methodology We use a combination of methods to project ultimate losses for both long-tail and short-tail exposures, which include: • Paid Development method: The Paid Development method estimates ultimate losses by reviewing paid loss patterns and selecting paid ultimate loss development factors. These factors are then applied to paid losses by applying them to accident years, with further expected changes in paid loss. Since the method does not rely on case reserves, it is not directly influenced by changes in the adequacy of case reserves. • Incurred Development method: The Incurred Development method is similar to the Paid Development method, but it uses case incurred losses instead of paid losses. Since this method uses more data (case reserves in addition to paid losses) than the Paid Development method, the incurred development patterns may be less variable than paid development patterns. • Expected Loss Ratio method: The Expected Loss Ratio method multiplies premiums by an expected loss ratio to produce ultimate loss estimates for each accident year. This method may be useful if loss development patterns are inconsistent, losses emerge very slowly, or there is relatively little loss history from which to estimate future losses. Expected loss ratio methods for business written in excess of a deductible may be given significant weight in the most recent five accident years. The expected loss ratios used for recent accident years are based on the projected ultimate loss ratios for older years adjusted for rate changes, loss trend including inflation, and where appropriate, changing market conditions. • Bornhuetter-Ferguson method: The Bornhuetter-Ferguson method using premiums and paid losses is a combination of the Paid Development method and the Expected Loss Ratio method where the weight given to each method is the reciprocal of the loss development factor. This method normally determines expected loss ratios similar to the method used for the Expected Loss Ratio method. The Bornhuetter-Ferguson method using premiums and incurred losses is similar to the Bornhuetter-Ferguson method using premiums and paid losses except that it uses case-incurred losses. • Cape Cod method: The Cape Cod method is mechanically similar to the Bornhuetter-Ferguson method with the difference being that the Expected Loss Ratio estimates are determined based on a weighting of the loss estimates that come from the Paid/Incurred Development Methods. This method may be more responsive to recent loss trends than the Bornhuetter-Ferguson method. • Average Loss method: The Average Loss method multiplies a projected number of ultimate claims by an estimated ultimate severity average loss for each accident year to produce ultimate loss estimates. Since projections of the ultimate number of claims are often less variable than projections of ultimate loss, this method can provide more reliable results for reserve categories where loss development patterns are inconsistent or too variable to be relied on exclusively. In updating our loss reserve estimates, we consider and evaluate inputs from many sources, including actual claims data, the performance of prior reserve estimates, observed industry trends, our internal peer review processes, including challenges and recommendations from our Enterprise Risk Management group, as well as the views of third-party actuarial firms. We use these inputs to improve our evaluation techniques, and to analyze and assess the change in estimated ultimate loss for each accident year by product line. Our analyses produce a range of indications from various methods, from which we select our best estimate. In determining the actual carried loss reserves, we consider both the internal actuarial best estimate and numerous other internal and external factors, including: • an assessment of economic conditions, including real GDP growth, inflation, employment rates or unemployment duration, stock market volatility and changes in corporate bond spreads; • changes in the legal, regulatory, judicial and social environment, including changes in road safety, public health and cleanup standards; • changes in medical cost trends (inflation, intensity and utilization of medical services) and wage inflation trends; • underlying policy pricing, terms and conditions including attachment points and policy limits; • change in claims handling philosophy, operating model, processes, and related ongoing enhancements; • third-party claims reviews that are periodically performed for key classes of claims such as toxic tort, environmental and other complex casualty claims; • third-party actuarial reviews that are periodically performed for key classes of business; • input from underwriters on pricing, terms, and conditions and market trends; and • changes in our reinsurance program, pricing and commutations. Where appropriate and identifiable, adjustments have been made to standard projection techniques. Changes in Claims organization management, differing referral and review criteria and other factors may also be expected to alter loss emergence. The following factors are relevant to the loss development information included in the tables below: • Table organization: The tables are organized by accident year and include policies written on an occurrence and claims- made basis. We note that for certain categories of claims (e.g., construction defect claims and environmental claims) and for reinsurance recoverable, losses may sometimes be reclassified to an earlier or later accident year as more information about the date of occurrence becomes available to us. These reclassifications are shown as development in the respective years in the tables below. Financial Lines business is primarily written on a claims-made basis, while the majority of the workers’ compensation, excess casualty, other casualty, and run-off property and casualty lines of business are written on an occurrence basis. Primarily, all short-tail lines in Property and Special Risks and Personal Insurance are written on an occurrence basis. • Groupings: We believe our groupings have homogenous risk characteristics with similar development patterns and would generally be subject to similar trends and reflect our reportable segments. The incurred losses and loss adjustment expenses and paid losses in the following tables for the current reporting year are allocated to the line of business and accident years based on how the business is coded by profit center and line of business. • Reinsurance: Our reinsurance program varies by exposure type. Historically we have leveraged facultative and treaty reinsurance, both on a pro-rata and excess of loss basis. Our reinsurance program may change from year to year, which may affect the comparability of the data presented in our tables. • Adverse development reinsurance agreement: We have provided the impact of the ADC in an additional table below our Incurred Losses and Allocated Loss Adjustment Expenses tables. The impact of the ADC is shown beginning in 2016 given the retroactive date of the contract and coincides with the effective date of the contract. For the lines of business covered by the agreement (U.S. Workers' Compensation, U.S. Excess Casualty, U.S. Other Casualty, U.S. Financial Lines, U.S. Property and Special Risks and U.S. Personal Insurance or collectively, the Covered Lines), an attribution of the loss recoveries to the line of business by calendar year and accident year is performed based on the underlying distribution of the losses subject to the agreement. Specifically, the future claim payments for all subject incurred losses were projected into future years based on the same actuarial assumptions underlying the related reserves. The additional table presented after discussion of prior year development by line of business reconciles the changes in net ultimates to our overall prior year development and provides the reattribution of loss recoveries for the Covered Lines. The reinsurance terms of the ADC were then used to identify the future claims payments for which 80% will be reimbursed by NICO. At each reporting period, the attribution of the ADC recoveries is performed. The factors that could cause the attribution to lines of business and accident year to change include changes in underlying actuarial assumptions as to timing and amount of future claim payments. • Incurred but not reported liabilities (IBNR): We include development from past reported losses in IBNR. • Data excluded from tables: Information with respect to accident years older than ten years is excluded from the development tables. Unallocated loss adjustment expenses are also excluded. • Foreign exchange: The loss development for operations outside of the U.S. is presented for all accident years using the current exchange rate at December 31, 2024. Although this approach requires restating all prior accident year information, the changes in exchange rates do not impact incurred and paid loss development trends. • Acquisitions: We include acquisitions from all accident years presented in the tables. For purposes of this disclosure, we have applied the retrospective method for the acquired reserves, including incurred and paid claim development histories throughout the relevant tables. It should be noted that historical reserves for the acquired businesses were established by the acquired companies using methods, assumptions and procedures then in effect which may differ from our current reserving bases. Accordingly, it may not be appropriate to extrapolate future redundancies or deficiencies based on the aggregated historical results shown in the triangles. • Dispositions: We exclude dispositions from all accident years presented in the tables. • Claim counts: We consider a reported claim to be one claim for each claimant or feature for each loss occurrence. Claims relating to losses that are 100 percent reinsured are excluded from the reported claims in the tables below. Reported claims for losses from assumed reinsurance contracts are not available and hence not included in the reported claims. There are limitations that should be considered on the reported claim count data in the tables below, including: – Claim counts are presented only on a reported (not an ultimate) basis; – The tables below include lines of business and geographies at a certain aggregated level which may indicate different frequency and severity trends and characteristics, and may not be as meaningful as the claim count information related to the individual products within those lines of business and geographies; – Certain lines of business are more likely to be subject to occurrences involving multiple claimants and features, which can distort measures based on the reported claim counts in the table below; and – Reported claim counts are not adjusted for ceded reinsurance, which may distort the measure of frequency or severity. Supplemental Information: The information about incurred and paid loss development for all periods preceding the year ended December 31, 2024 and the related historical claims payout percentage disclosure is unaudited and is presented as supplementary information. The following tables present undiscounted, incurred and paid losses and allocated loss adjustment expenses by accident year, on a net basis after reinsurance, with a separate presentation of the ADC excluding the related amortization of the deferred gain: U.S. Workers' Compensation U.S. Workers’ Compensation is an extremely long-tail line of business, with loss emergence extending for decades. We generally use a combination of loss development, frequency/severity and expected loss ratio methods for workers’ compensation. Many of our workers compensation policies contain risk-sharing features, including high deductibles, self-insured retentions or retrospective rating features, in addition to a traditional insurance component. These risk-sharing programs generally are large and complex, comprising multiple products, years and structures, and are subject to amendment over time. We group guaranteed cost and excess of deductible business separately and then further by state and industry subset to the extent that meaningful differences are determined to exist. We also separately analyze certain subsets of the portfolio that have unique characteristics (e.g., U.S. government sub-contractor accounts and construction wrap-up business). For excess of deductible business, we also segment by size of deductible and whether the claim is handled by AIG or an outside third-party administrator. The proportion of large deductible business has increased over time, which has slowed the reporting pattern of claims.

DEBT CASH TENDER OFFERS AND REDEMPTIONS In 2024, we repaid, redeemed and repurchased $2.0 billion aggregate principal amount of certain notes and debentures issued or guaranteed by AIG, for an aggregate purchase price of $2.1 billion, resulting in a total loss on extinguishment of debt of $14 million. This includes the following: • Repayment of $459 million aggregate principal amount of our 4.125% Notes due February 15, 2024. • Redemption of €41.55 million aggregate principal amount of our Series A-3 Junior Subordinated Debentures, equivalent to approximately $46 million at the time of repayment. • Redemption of $400 million aggregate principal amount of our Zero Coupon Callable Notes Due 2047, for a purchase price of approximately $543 million . • Repurchased, through cash tender offers, approximately $1.13 billion aggregate principal amount of certain notes and debentures issued by AIG for an aggregate purchase price of approximately $1.14 billion. CREDIT FACILITIES On September 27, 2024, AIG entered into the amended and restated credit agreement (Amended Credit Agreement) that amends and restates AIG's credit agreement, dated as of November 19, 2021, which provides for a syndicated, multicurrency revolving credit facility as a potential source of liquidity for general corporate purposes. The Amended Credit Agreement provides for a five-year total commitment of $3.0 billion, consisting of standby letters of credit and/or revolving credit borrowings. Under circumstances described in the Amended Credit Agreement, the aggregate commitments may be increased by up to $1.5 billion, for a total commitment of up to $4.5 billion. Under the Amended Credit Agreement, the applicable rate, commitment fee and letter of credit fee are determined by reference to the credit ratings of AIG’s senior long-term unsecured debt. The Amended Credit Agreement is scheduled to expire in September 2029.

Commitments and Contingencies Disclosure [Abstract]
Contingencies, Commitments and Guarantees	15. Contingencies, Commitments and Guarantees In the normal course of business, we enter into various contingent liabilities and commitments. In addition, AIG Parent guarantees various obligations of certain subsidiaries. Although we cannot currently quantify our ultimate liability for unresolved litigation and investigation matters, including those referred to below, it is possible that such liability could have a material adverse effect on our consolidated financial condition or consolidated results of operations or consolidated cash flows for an individual reporting period. LEGAL CONTINGENCIES In the normal course of business, we are subject to regulatory and government investigations and actions, and litigation and other forms of dispute resolution in a large number of proceedings pending in various domestic and foreign jurisdictions. Certain of these matters involve potentially significant risk of loss due to potential for significant jury awards and settlements, punitive damages or other penalties. Many of these matters are also highly complex and may seek recovery on behalf of a class or similarly large number of plaintiffs. It is therefore inherently difficult to predict the size or scope of potential future losses arising from these matters. In our insurance and reinsurance operations, litigation and arbitration concerning the scope of coverage under insurance and reinsurance contracts, and litigation and arbitration in which our subsidiaries defend or indemnify their insureds under insurance contracts, are generally considered in the establishment of our loss reserves. Separate and apart from the foregoing matters involving insurance and reinsurance coverage, AIG Parent, our subsidiaries and their respective officers and directors are subject to a variety of additional types of legal proceedings brought by holders of AIG securities, customers, employees and others, alleging, among other things, breach of contractual or fiduciary duties, bad faith, indemnification and violations of federal and state statutes and regulations. With respect to these other categories of matters not arising out of claims for insurance or reinsurance coverage, we establish reserves for loss contingencies when it is probable that a loss will be incurred and the amount of the loss can be reasonably estimated. In many instances, we are unable to determine whether a loss is probable or to reasonably estimate the amount of such a loss and, therefore, the potential future losses arising from legal proceedings may exceed the amount of liabilities that we have recorded in our financial statements covering these matters. While such potential future charges could be material, based on information currently known to management, management does not believe that any such charges are likely to have a material adverse effect on our financial position or results of operation. Additionally, from time to time, various regulatory and governmental agencies review our transactions and practices in connection with industry-wide and other inquiries or examinations into, among other matters, the business practices of current and former operating insurance subsidiaries. Such investigations, inquiries or examinations could develop into administrative, civil or criminal proceedings or enforcement actions, in which remedies could include fines, penalties, restitution or alterations in our business practices, and could result in additional expenses, limitations on certain business activities and reputational damage. LEASE COMMITMENTS We lease office space and equipment in various locations across jurisdictions in which the Company operates. The majority of the resulting obligation arising from these contracts is generated by our real estate portfolio, which only includes contracts classified as operating leases. The lease liability and corresponding right of use asset reflected in Other liabilities Other assets The weighted average discount rate and lease term assumptions used in determining the liability are 3.36 percent and 10.1 years, respectively. The primary assumption used to determine the discount rate is the cost of funding for the Company, which is based on the secured borrowing rate for terms similar to the lease term, and for the major financial markets in which AIG operates. Rent expense was $164 million, $162 million and $174 million for the years ended December 31, 2024, 2023 and 2022, respectively. The following table presents the future undiscounted cash flows under operating leases at December 31, 2024: (in millions) 2025 $ 143 2026 95 2027 88 2028 76 2029 78 Remaining years after 2029 578 Total undiscounted lease payments 1,058 Less: Present value adjustment 190 Net lease liabilities $ 868 OTHER COMMITMENTS In the normal course of business, we enter into commitments to invest in limited partnerships, private equity funds and hedge funds and to purchase and develop real estate in the U.S. and abroad. These commitments totaled $1.8 billion and $1.7 billion at December 31, 2024 and 2023, respectively. GUARANTEES Subsidiaries We have issued unconditional guarantees with respect to the prompt payment, when due, of all present and future payment obligations and liabilities of AIGFP and certain of its subsidiaries. We have also issued guarantees of all present and future payment obligations and liabilities of AIG Markets, Inc. Due to the deconsolidation of AIGFP and its subsidiaries, as of December 31, 2024, a $100 million guarantee related to the obligations of AIGFP and certain of its subsidiaries was recognized, and is reported in Other liabilities. We continue to guarantee certain policyholder contracts issued by Corebridge subsidiaries as well as certain debt issued by Corebridge Life Holdings, Inc. (CRBGLH). Pursuant to the Separation Agreement entered in by AIG and Corebridge on September 14, 2022, Corebridge must indemnify, defend and hold us harmless from and against any liability related to these guarantees. Also, under a collateral agreement, in the event of: (i) a ratings downgrade of Corebridge or the guaranteed debt below specified levels or (ii) the failure by CRBGLH to pay principal and interest on the guaranteed debt when due, Corebridge must collateralize an amount equal to the sum of: (i) 100 percent of the principal amount outstanding, (ii) accrued and unpaid interest and (iii) 100 percent of the net present value of scheduled interest payments through the maturity dates of the debt. Business and Asset Dispositions We are subject to financial guarantees and indemnity arrangements in connection with the completed sales of businesses and assets. The various arrangements may be triggered by, among other things, declines in asset values, the occurrence of specified business contingencies, the realization of contingent liabilities, developments in litigation or breaches of representations, warranties or covenants provided by us. These arrangements are typically subject to various time limitations, defined by the contract or by operation of law, such as statutes of limitation. In some cases, the maximum potential obligation is subject to contractual limitations, while in other cases such limitations are not specified or are not applicable. We are unable to develop a reasonable estimate of the maximum potential payout under certain of these arrangements. Overall, we believe the likelihood that we will have to make any material payments related to completed sales under these arrangements is remote, and no material liabilities related to these arrangements have been recorded in the Consolidated Balance Sheets.

Equity SHARES OUTSTANDING Preferred Stock On March 14, 2019, we issued 20,000 shares of Series A 5.85% Non-Cumulative Perpetual Preferred Stock (Series A Preferred Stock) (equivalent to 20,000,000 Depositary Shares (the Depositary Shares), each representing a 1/1,000th interest in a share of Series A Preferred Stock), $5.00 par value and $25,000 liquidation preference per share (equivalent to $25 per Depositary Share). On March 15, 2024, we redeemed all 20,000 outstanding shares of our Series A Preferred Stock and all 20,000,000 of the corresponding Depositary Shares, each representing a 1/1,000th interest in a share of Series A Preferred Stock, for a redemption price of $25,000 per share (equivalent to $25.00 per Depositary Share) for an aggregate redemption price of $500 million, paid in cash.

In considering whether to pay a dividend on or purchase shares of AIG Common Stock, our Board of Directors considers a number of factors, including, but not limited to: the capital resources available to support our insurance operations and business strategies, AIG’s funding capacity and capital resources in comparison to internal benchmarks, expectations for capital generation, rating agency expectations for capital, regulatory standards for capital and capital distributions, and such other factors as our Board of Directors may deem relevant. Repurchase of AIG Common Stock Shares may be repurchased from time to time in the open market, private purchases, through forward, derivative, accelerated repurchase or automatic repurchase transactions or otherwise. Certain of our share repurchases have been and may from time to time be effected through the Securities Exchange Act of 1934, as amended (the Exchange Act) Rule 10b5-1 repurchase plans. On April 30, 2024, the Board of Directors authorized the repurchase of $10.0 billion of AIG Common Stock (inclusive of the approximately $3.9 billion remaining under the Board's prior share repurchase authorization). The timing of any future repurchases will depend on market conditions, our business and strategic plans, financial condition, results of operations, liquidity and other factors. Pursuant to an Exchange Act Rule 10b5-1 repurchase plan, from January 1, 2025 to February 7, 2025, we repurchased approximately 13 million shares of AIG Common Stock for an aggregate purchase price of approximately $952 million.

Earnings Per Share [Abstract]
Earnings Per Common Share (EPS)	17. Earnings Per Common Share (EPS) The basic EPS computation is based on the weighted average number of common shares outstanding, adjusted to reflect all stock dividends and stock splits. The diluted EPS computation is based on those shares used in the basic EPS computation plus common shares that would have been outstanding assuming issuance of common shares for all dilutive potential common shares outstanding and adjusted to reflect all stock dividends and stock splits, using the treasury stock method or the if-converted method, as applicable. The following table presents the computation of basic and diluted EPS: Years Ended December 31, (dollars in millions, except per common share data) 2024 2023 2022 Numerator for EPS: Income (loss) from continuing operations $ 2,700 $ 2,741 $ 2,890 Less: Preferred stock dividends and preferred stock redemption premiums 22 29 29 Income (loss) attributable to AIG common shareholders from continuing operations 2,678 2,712 2,861 Income (loss) from discontinued operations, net of income tax expense (3,626) 1,137 8,383 Less: Net income attributable to noncontrolling interests 478 235 1,046 Income (loss) from discontinued operations, net of noncontrolling interest (4,104) 902 7,337 Net income (loss) attributable to AIG common shareholders $ (1,426) $ 3,614 $ 10,198 Denominator for EPS: Weighted average common shares outstanding - basic 651,448,307 719,506,291 778,621,118 Dilutive common shares 5,834,853 5,726,777 9,320,632 Weighted average common shares outstanding - diluted (a) 657,283,160 725,233,068 787,941,750 Income (loss) per common share attributable to AIG common shareholders: Basic: Income (loss) from continuing operations $ 4.11 $ 3.77 $ 3.67 Income (loss) from discontinued operations $ (6.30) $ 1.25 $ 9.43 Income (loss) attributable to AIG common shareholders $ (2.19) $ 5.02 $ 13.10 Diluted: Income (loss) from continuing operations $ 4.07 $ 3.74 $ 3.63 Income (loss) from discontinued operations $ (6.24) $ 1.24 $ 9.31 Income (loss) attributable to AIG common shareholders $ (2.17) $ 4.98 $ 12.94 (a) Potential dilutive common shares are primarily due to our share-based employee compensation plans. The number of potential common shares excluded from diluted shares outstanding was 0.1 million, 4.4 million and 24.1 million for the years ended December 31, 2024, 2023 and 2022, respectively, because the effect of including those common shares in the calculation would have been anti-dilutive.

Statutory Financial Data and Restrictions	18. Statutory Financial Data and Restrictions The following table presents statutory net income (loss) and capital and surplus for our General Insurance companies in accordance with statutory accounting practices: (in millions) 2024 2023 2022 Years Ended December 31, Statutory net income (loss) (a)(b) : General Insurance companies: Domestic $ 1,594 $ 1,912 $ 2,272 Foreign 1,741 1,867 1,047 Total General Insurance companies $ 3,335 $ 3,779 $ 3,319 At December 31, Statutory capital and surplus (a)(b) : General Insurance companies: Domestic $ 17,001 $ 18,703 Foreign 12,299 11,527 Total General Insurance companies $ 29,300 $ 30,230 Aggregate minimum required statutory capital and surplus: General Insurance companies: Domestic $ 3,763 $ 3,625 Foreign 5,741 6,041 Total General Insurance companies $ 9,504 $ 9,666 (a) Excludes discontinued operations and other divested businesses. (b) The 2024 statutory net income and capital and surplus reflect our best estimate as of the date of AIG’s Form 10-K filing. Our insurance subsidiaries file financial statements prepared in accordance with statutory accounting practices prescribed or permitted by domestic and foreign insurance regulatory authorities. The principal differences between statutory financial statements and financial statements prepared in accordance with U.S. GAAP for domestic companies are that statutory financial statements do not reflect DAC, some bond portfolios may be carried at amortized cost, investment impairments are determined in accordance with statutory accounting practices, assets and liabilities are presented net of reinsurance, policyholder liabilities are generally valued using more conservative assumptions and certain assets are non-admitted. For domestic insurance subsidiaries, aggregate minimum required statutory capital and surplus is based on the greater of the Risk-Based Capital (RBC) level that would trigger regulatory action or minimum requirements per state insurance regulation. Capital and surplus requirements of our foreign subsidiaries differ from those prescribed in the U.S., and can vary significantly by jurisdiction. At both December 31, 2024 and 2023, all domestic and foreign insurance subsidiaries individually exceeded the minimum required statutory capital and surplus requirements and all domestic insurance subsidiaries individually exceeded RBC minimum required levels. For foreign insurance companies, financial statements are prepared in accordance with local regulatory requirements. These accounting practices differ from U.S. GAAP primarily by different rules on deferral of policy acquisition costs, amortization of deferred acquisition costs, and establishing future policy benefit liabilities using different actuarial assumptions, as well as valuing for deferred taxes on a different basis. SUBSIDIARY DIVIDEND RESTRICTIONS Payments of dividends to us by our insurance subsidiaries are subject to certain restrictions imposed by regulatory authorities. With respect to our domestic insurance subsidiaries, the payment of any dividend requires formal notice to the insurance department in which the particular insurance subsidiary is domiciled. For example, unless permitted by the Superintendent of Financial Services, property casualty companies domiciled in New York generally may not pay dividends to shareholders that, in any 12-month period, exceed the lesser of 10 percent of such company’s statutory policyholders’ surplus or 100 percent of its “adjusted net investment income,” for the previous year, as defined. Generally, less severe restrictions applicable to property casualty companies exist in most of the other states in which our insurance subsidiaries are domiciled. Under state insurance laws, an insurer may pay a dividend without prior approval of the insurance regulator when the amount of the dividend is below certain regulatory thresholds. Other foreign jurisdictions may restrict the ability of our foreign insurance subsidiaries to pay dividends. Various other regulatory restrictions also limit cash loans and advances to us by our subsidiaries. The amount of dividends available to be paid in 2025 from our insurance subsidiaries without prior regulatory approval was $2.5 billion at December 31, 2024. To our knowledge, no AIG insurance company is currently on any regulatory or similar “watch list” with regard to solvency. PARENT COMPANY DIVIDEND RESTRICTIONS At December 31, 2024, our ability to pay dividends is not subject to any significant contractual restrictions, but remains subject to regulatory restrictions. For additional information about our ability to pay dividends to our shareholders, see Note 16.

Share-Based Payment Arrangement [Abstract]
Share-Based Compensation Plans	19. Share-Based Compensation Plans The following table presents our total share-based compensation expense: Years Ended December 31, (in millions) 2024 2023 2022 Share-based compensation expense - pre-tax (a) $ 211 $ 199 $ 288 Share-based compensation expense - after tax (b) 167 157 228 (a) As a result of accelerated vesting events, such as retirement eligibility in the year of grant and involuntary terminations, we recognized $52 million, $58 million and $67 million in 2024, 2023 and 2022, respectively, prior to the end of the specified vesting periods. It is our policy to reverse compensation expense for forfeited awards when they occur. (b) We also recognized $16 million of tax benefit due to share settlements occurring in 2024. EMPLOYEE PLANS The Company sponsors several stock compensation programs under the AIG Long Term Incentive Plan (LTIP) (as amended) and its predecessor plan from which performance share units (PSUs), restricted stock units (RSUs), stock options and deferred stock units (DSUs) (collectively units) are issued. In addition, off-cycle grants are made from time to time during the year generally as sign-on awards to new hires or as a result of a change in employee status. The LTIP is governed by the AIG 2021 Omnibus Incentive Plan (2021 Omnibus Plan), which was adopted at the annual shareholders’ meeting in May 2021, replacing the AIG 2013 Omnibus Incentive Plan (2013 Plan). Our share-settled awards are settled with previously acquired shares held in AIG’s treasury. AIG Omnibus Incentive Plan The 2021 Omnibus Plan provided for the grants of share-based awards to our employees and non-employee directors. The total number of shares granted under the 2021 Plan (the reserve) was the sum of 1) 8.1 million shares of AIG Common Stock, plus 2) the number of authorized shares that remained available for issuance under the 2013 Plan when the 2021 Omnibus Plan became effective, plus 3) the number of shares of AIG Common Stock relating to outstanding awards under the 2013 Plan at the time the 2021 Omnibus Plan became effective that subsequently were forfeited, expired, terminated or otherwise lapse or are settled in cash. Each share-based unit granted under the Omnibus Plan reduces the number of shares available for future grants by one share. However, shares with respect to awards that are forfeited, expired or settled for cash are returned to the reserve. As of December 31, 2024, 23,168,953 shares are available for future grants. AIG Long Term Incentive Plan Long-Term Incentive (LTI) Awards The LTIP provides for an annual award to certain employees, including our senior executive officers and other highly compensated employees that may be comprised of a combination of one or more of the following units: PSUs, RSUs or stock options. The number of PSUs issued on the grant date (the target) provides the opportunity for LTIP participants (usually senior management) to receive shares of AIG Common Stock based on AIG achieving specified performance goals at the end of a three-year performance period. These performance goals are pre-established by AIG’s Compensation and Management Resources Committee (CMRC) for each annual grant and may differ from year to year. The actual number of PSUs earned can vary from zero to 200 percent of the target for the 2024, 2023 and 2022 LTI awards, depending on AIG’s performance relative to a specified peer group and/or the outcome of pre-established financial goals, as applicable. RSUs and stock options are earned based solely on continued service by the participant. In addition, PSUs and RSUs accrue dividend equivalent rights (DERs) during the specified service period as AIG’s dividends are declared. These DERs are settled in cash only if the underlying units’ vesting conditions are met. Vesting occurs on January 1 of the year immediately following the end of the three-year performance and service period. Beginning in 2022, vesting for RSUs and stock options awarded occurs in three equal installments on the first, second and third anniversary of the grant date. Recipients must be employed at each vesting date to be entitled to share delivery, except upon the occurrence of an accelerated vesting event, such as an involuntary termination without cause, disability, retirement eligibility or death during the vesting period. However, for involuntarily terminated employees hired after April 1, 2022 unvested RSUs and options are forfeited on the termination date, while PSUs are pro-rated based on the number of completed years in the performance period. Unit Valuation The fair value of time-vesting RSUs as well as PSUs that are earned based on certain company-specific metrics was based on the closing price of AIG Common Stock on the grant date; while the fair value of PSUs that are earned based on AIG’s relative total shareholder return (TSR) was determined on the grant date using a Monte Carlo simulation. The following table presents the assumptions used to estimate the fair value of PSUs that vest based on AIG’s TSR: 2024 2023 2022 Expected dividend yield (a) — % — % — % Expected volatility (b) 28.72 % 37.98 % 47.60 % Risk-free interest rate (c) 4.36 % 4.42 % 1.71 % (a) The award agreement provides that TSR for AIG and each member of the Peer Group will be calculated assuming dividends distributed are reinvested on the ex‑dividend date. (b) We used the historical volatility over the most recent 2.86-year period for AIG and the members of the Peer Group, commensurate with the remaining Performance Period as of the valuation date. (c) We converted the semi-annual zero-coupon U.S. Treasury rates as of the valuation date to continuously compounded rates. We then chose the continuously compounded risk-free rate that is commensurate with the length of the remaining performance period as of the valuation date and interpolated between the yields of the two-year and the three-year continuously compounded rates to determine the yield. The following table summarizes outstanding share-settled LTI awards (a) : Number of Units Weighted Average Grant-Date Fair Value Year Ended December 31, 2024 (b) 2024 LTI 2023 LTI 2022 LTI 2021 LTI 2024 LTI 2023 LTI 2022 LTI 2021 LTI Unvested, beginning of year — 1,734,969 1,108,153 1,727,851 $ — $ 60.02 $ 61.95 $ 45.08 Granted 2,140,298 — — — 68.31 — — — Vested (c) (675,495) (652,758) (743,117) (1,721,506) 68.27 59.86 62.13 45.08 Forfeited (99,414) (111,860) (55,994) (6,345) 68.19 59.89 65.07 44.10 Unvested, end of year (d) 1,365,389 970,351 309,042 — $ 68.34 $ 60.14 $ 60.94 $ — (a) Excludes stock options, other RSUs and DSUs, which are discussed under Stock Options, Other RSU Grants and Non-Employee Plan, respectively. (b) PSUs represent target amount granted and does not reflect potential increases or decreases that could result from the final outcome of the performance goals for the respective awards, which is determined by the CMRC in the quarter after the applicable performance period ends. (c) Also reflects units that vest as a result of an accelerated vesting event that occurred prior to the specified vesting date but for which share delivery has not yet occurred. (d) At December 31, 2024, the total unrecognized compensation cost for outstanding RSUs and PSUs was $96 million and the weighted-average and expected period of years over which that cost is expected to be recognized are 1.00 year and 2.25 years. Stock Options Stock options were issued as part of the 2024, 2023 and 2022 LTI awards, and to certain newly hired senior executives in 2017 and 2018. Option awards are generally granted with an exercise price equal to the market price of the company’s stock on the grant date and are exercisable up to 10 years from the date of grant, or 3 years from the date of an involuntary termination or the option's expiration date, if earlier. The fair value of the options was estimated on the grant date using the Black-Scholes model for the time-vesting options, and a Monte Carlo simulation for the hurdle-vesting options. The following weighted-average assumptions were used for stock options granted: 2024 2023 2022 Expected annual dividend yield (a) 2.11 % 2.14 % 2.08 % Expected volatility (b) 25.27 % 25.17 % 32.13 % Risk-free interest rate (c) 4.21 % 4.06 % 1.92 % Expected term (d) 6.00 years 6.00 years 6.00 years (a) The dividend yield is the last dividend from Bloomberg times 4 divided by stock price based on Bloomberg Professional service as of the valuation date. (b) The expected volatility is based on the implied volatility of 24 months stock option estimated by the Bloomberg Professional service as of the valuation date. (c) We converted the semi-annual zero-coupon U.S. Treasury rates as of the valuation date to continuously compounded rates. We then chose the continuously compounded risk-free rate that is commensurate with the length of the remaining performance period as of the valuation date and interpolated between the yields of the two-year and the three-year continuously compounded rates to determine the yield. (d) The contractual term is 10 years from the date of grant. The following table provides a rollforward of stock option activity: As of or for the Year Ended December 31, 2024 Units Weighted Weighted Average Aggregate Outstanding, beginning of year 12,295,661 $ 50.69 6.81 Granted 1,080,790 68.19 Exercised (3,071,453) 52.62 Forfeited or expired (1,287,410) 62.82 Outstanding, end of year 9,017,588 $ 50.40 6.61 $ 202 Exercisable, end of year 7,263,927 $ 46.94 5.87 $ 188 The weighted average grant-date fair value of stock options granted during 2024, 2023 and 2022 was $12.51, $11.43 and $10.77, respectively. As of December 31, 2024, we recognized $18 million of expense, while $13 million was unrecognized and is expected to be amortized up to 2.25 years. We received $162 million in cash from the exercise of stock options during 2024. Other RSU Grants The Company may issue time-vesting RSUs for various reasons including, as a sign-on bonus, retention grant or replacement award in an acquisition. Vesting for these awards ranges from 1 to 5 years and is contingent on continuous service. The following table summarizes outstanding share-settled Other RSU grants. Number of Units Weighted Average Grant-Date Fair Value Years Ended December 31, 2024 2023 2022 2024 2023 2022 Unvested, beginning of year 1,361,714 1,488,248 728,340 $ 57.79 $ 54.77 $ 42.82 Granted 241,536 208,641 1,070,458 73.78 62.42 60.16 Vested (264,588) (252,635) (290,037) 52.82 49.42 44.59 Forfeited (20,382) (82,540) (20,513) 64.03 40.70 55.89 Unvested, end of year 1,318,280 1,361,714 1,488,248 $ 61.62 $ 57.79 $ 54.77 We recognized $29 million of expense related to these RSU grants in 2024. Total unrecognized compensation cost related to these grants was $42 million and the weighted-average and expected period of years over which that cost is expected to be recognized are 1.09 years and 4.25 years at December 31, 2024. NON-EMPLOYEE PLAN Our non-employee directors, who serve on our Board of Directors, receive share-based compensation in the form of fully vested DSUs with delivery deferred until retirement from the Board of Directors. DSUs granted in 2024, 2023 and 2022 accrue dividend equivalents in the form of additional DSUs equal to the amount of any regular quarterly dividend that would have been paid by AIG if the shares of AIG Common Stock underlying the DSUs had been outstanding. In 2024, 2023 and 2022, we granted to non-employee directors 33,940, 47,344 and 46,273 DSUs, respectively, and recognized expense of $2.6 million, $2.6 million and $2.7 million, respectively.

Retirement Benefits [Abstract]
Employee Benefits	20. Employee Benefits PENSION PLANS We offer various defined benefit plans to eligible employees. Effective January 1, 2016, the U.S. defined benefit pension plans were frozen. Consequently, these plans are closed to new participants and current participants no longer earn benefits. The U.S. AIG Retirement Plan (the qualified plan) is a noncontributory defined benefit plan subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA). In 2012, the qualified plan was converted to a cash balance formula comprised of pay credits based on 6% of a plan participant’s annual compensation (subject to IRS limitations) and annual interest credits. Although benefits are frozen, these interest credits continue to accrue on the cash balance accounts of active participants, who also accrue years of service for purposes of early retirement eligibility and subsidies. Employees can take their vested benefits as a lump sum or an annuity option when they leave AIG or are terminated from the plan. Employees satisfying certain age and service requirements (i.e., grandfathered employees) remain covered under the average pay formula that was in effect prior to the conversion. The final average pay formula is based upon a percentage of final average compensation multiplied by years of credited service, up to 44 years. Grandfathered employees will receive the higher of the benefit under the cash balance formula or the final average pay formula at retirement. In the U.S. we also sponsor non-qualified unfunded defined benefit plans, such as the AIG Non-Qualified Retirement Income Plan (AIG NQRIP) for certain employees, including key executives, designed to supplement pension benefits provided by the qualified plan. The AIG NQRIP provides a benefit equal to the reduction in benefits under the qualified plan as a result of federal tax limitations on compensation and benefits payable. Non-U.S. defined benefit plans generally are either based on the employee’s years of credited service and compensation in the years preceding retirement or on points accumulated based on the employee’s job grade and other factors during each year of service. POSTRETIREMENT PLANS U.S. postretirement medical and life insurance benefits are based upon the employee attaining the age of 55 and having a minimum of ten years of service, which was reduced to 5 years in 2019 for medical coverage only. Eligible employees who have medical coverage can enroll in retiree medical upon termination of employment. Medical benefits are contributory, while the life insurance benefits, which are closed to new employees, are generally non-contributory. Retiree medical contributions vary from none for pre-1989 retirees to actual premium payments reduced by certain subsidies for post-1992 retirees. These retiree contributions are subject to annual adjustments. Other cost sharing features of the medical plan include deductibles, coinsurance, Medicare coordination, and an employer subsidy for grandfathered employees only. Postretirement benefits are offered in certain non-U.S. countries and vary by geographic location. The following table presents the funded status of the plans reconciled to the amount reported in the Consolidated Balance Sheets.

Interest cost for pension and postretirement benefits for our U.S. plans and largest non-U.S. plans is measured using the spot rate approach, which applies specific spot rates along the yield curve to a plan’s corresponding discounted cash flows that comprise the obligation. This method provides a more precise measurement of interest cost by aligning the timing of the plans’ discounted cash flows to the corresponding spot rates on the yield curve. For certain non-U.S. plans, interest cost is measured utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligations. A 100 basis point increase in the expected long-term rate of return would decrease the 2025 pension expense by approximately $35 million with all other items remaining the same. A 100 basis point increase in the discount rate would increase the 2025 pension expense by approximately $2 million. Conversely, a 100 basis point decrease in the discount rate would decrease the 2024 pension expense by approximately $3 million while a 100 basis point decrease in the expected long-term rate of return would increase the 2025 pension expense by approximately $35 million, with all other items remaining the same. ASSUMPTIONS The following table summarizes the weighted average assumptions used to determine the benefit obligations: Pension Postretirement U.S. Plans Non-U.S. Plans (a) U.S. Plans Non-U.S. Plans (a) December 31, 2024 Discount rate 5.57 % 2.87 % 5.53 % 4.97 % Interest crediting rate 4.37 % 1.36 % (b) N/A N/A Rate of compensation increase N/A (c) 2.43 % N/A N/A December 31, 2023 Discount rate 4.98 % 2.85 % 4.97 % 5.37 % Interest crediting rate 4.94 % 1.40 % (b) N/A N/A Rate of compensation increase N/A (c) 2.42 % N/A N/A (a) The non-U.S. plans reflect those assumptions that were most appropriate for the local economic environments of each of the subsidiaries providing such benefits.

(c) Compensation increases are no longer applicable as the plan is frozen effective January 1, 2016. The following table summarizes assumed health care cost trend rates for the U.S. plans: At December 31, 2024 2023 Following year: Medical (before age 65) — % 5.78 % Medical (age 65 and older) 6.67 % 4.93 % Ultimate rate to which cost increase is assumed to decline 4.00 % 4.00 % Year in which the ultimate trend rate is reached: Medical (before age 65) 2048 2046 Medical (age 65 and older) 2048 2046 The following table presents the weighted average assumptions used to determine the net periodic benefit costs: Pension Postretirement U.S. Plans Non-U.S. Plans (a) U.S. Plans Non-U.S. Plans (a) For the Year Ended December 31, 2024 Discount rate 4.98 % 2.85 % 4.96 % 5.37 % Interest crediting rate 4.94 % 1.40 % (b) N/A N/A Rate of compensation increase N/A 2.42 % N/A N/A Expected return on assets 6.50 % 2.77 % N/A N/A For the Year Ended December 31, 2023 Discount rate 5.22 % 2.51 % 5.19 % 5.23 % Interest crediting rate 4.02 % 1.07 % (b) — % N/A Rate of compensation increase N/A 2.38 % N/A N/A Expected return on assets 6.25 % 2.67 % — % N/A For the Year Ended December 31, 2022 Discount rate 2.75 % 1.09 % 2.87 % 2.89 % Interest crediting rate 2.06 % 0.70 % (b) N/A N/A Rate of compensation increase N/A 2.40 % N/A N/A Expected return on assets 4.65 % 1.84 % N/A N/A (a) The non-U.S. plans reflect those assumptions that were most appropriate for the local economic environments of each of the subsidiaries providing such benefits. (b) Represents the weighted average interest crediting rate of non-U.S. cash balance plans primarily in Japan and Switzerland. Discount Rate Methodology The projected benefit cash flows under the U.S. AIG Retirement Plan were discounted using the spot rates derived from the Mercer U.S. Pension Discount Yield Curve (Mercer Yield Curve) at December 31, 2024 and 2023, which resulted in a single discount rate that would produce the same liability at the respective measurement dates . The discount rates were 5.57 percent at December 31, 2024 and 4.98 percent at December 31, 2023. The methodology was consistently applied for the respective years in determining the discount rates for the other U.S. pension plans. In general, the discount rates for the non-U.S. plans were developed using a similar methodology to the U.S. AIG Retirement Plan, by using country-specific Mercer Yield Curves. The projected benefit obligation for AIG’s Japan pension plans represents approximately 50 percent and 54 percent of the total projected benefit obligations for our non-U.S. pension plans at December 31, 2024 and 2023, respectively. The weighted average discount rate of 1.81 percent and 1.48 percent at December 31, 2024 and 2023, respectively, was selected by reference to the Mercer Yield Curve for Japan. Plan Assets The investment strategy with respect to assets relating to our U.S. and non-U.S. pension plans is designed to achieve investment returns that will provide for the benefit obligations of the plans over the long term, limit the risk of short-term funding shortfalls and maintain liquidity sufficient to address cash needs. Accordingly, the asset allocation strategy is designed to maximize the investment rate of return while managing various risk factors, including, but not limited to, volatility relative to the benefit obligations, liquidity, and concentration, and incorporates the risk/return profile applicable to each asset class. There were no shares of AIG Common Stock included in the U.S. and non-U.S. pension plans assets at December 31, 2024 or 2023. U.S. Pension Plan The assets of the qualified plan are monitored by the AIG U.S. Investment Committee and actively managed by the investment managers, which involves allocating the plan’s assets among approved asset classes within ranges as permitted by the strategic allocation. The long-term strategic asset allocation historically has been reviewed and revised approximately every three years. The investment strategy is focused on de-risking the qualified plan via regular monitoring through liability driven investing and the glide path approach, where the glide path defines the target allocation for the “Return-Seeking” portion of the portfolio (i.e., growth assets) based on the funded ratio and level of interest rates. Under this approach, the allocation to growth assets is reduced and the allocation to liability-hedging assets is increased as the plan’s funded ratio increases in accordance with the defined glide path. The following table presents the asset allocation percentage by major asset class for the U.S. qualified plan and the target allocation for 2025 based on the plan’s funded status at December 31, 2024: At December 31, Target 2025 Actual 2024 Actual 2023 Asset class: Equity securities 9 % 13 % 8 % Fixed maturity securities 80 72 77 Other investments 11 15 15 Total 100 % 100 % 100 % The expected weighted average long-term rate of return for the plan was 6.50 percent and 6.25 percent for 2024 and 2023, respectively. The expected weighted average rate of return is an aggregation of expected returns within each asset class category, weighted for the investment mix of the assets. The combination of the expected asset return and any contributions made by us are expected to maintain the plan’s ability to meet all required benefit obligations. The expected asset return for each asset class was developed based on an approach that considers key fundamental drivers of the asset class returns in addition to historical returns, current market conditions, asset volatility and the expectations for future market returns. Non-U.S. Pension Plans The assets of the non-U.S. pension plans are held in various trusts in multiple countries and are invested primarily in equities and fixed maturity securities to maximize the long-term return on assets for a given level of risk. The following table presents the asset allocation percentage by major asset class for non-U.S. pension plans and the target allocation: At December 31, Target 2025 Actual 2024 Actual 2023 Asset class: Equity securities 20 % 20 % 19 % Fixed maturity securities 58 47 45 Other investments 18 24 21 Cash and cash equivalents 4 9 15 Total 100 % 100 % 100 % The assets of AIG’s Japan pension plans represent approximately 66 percent and 67 percent of total non-U.S. pension plan assets at December 31, 2024 and 2023, respectively. The expected long-term rate of return was 1.85 percent for both 2024 and 2023, and is evaluated by the Japanese Pension Investment Committee on a quarterly and annual basis along with various investment managers and is revised to achieve the optimal allocation to meet targeted funding levels if necessary. In addition, the funding policy is revised in accordance with local regulation every five years. The expected weighted average long-term rate of return for all our non-U.S. pension plans was 2.77 percent and 2.67 percent for the years ended December 31, 2024 and 2023, respectively. It is an aggregation of expected returns within each asset class that was generally developed based on the building block approach that considers historical returns, current market conditions, asset volatility and the expectations for future market returns. ASSETS MEASURED AT FAIR VALUE The following table presents information about our plan assets and indicates the level of the fair value measurement based on the observability of the inputs used.

Contributed amounts in excess of the minimum amounts are deemed voluntary. Amounts in excess of the maximum amount would be subject to an excise tax and may not be deductible under the Internal Revenue Code. There are no minimum required cash contributions in 2024 for the U.S. AIG Retirement Plan. The non-qualified and postretireme nt plans’ benefit payments are deductible when paid to participants. Our annual pension contribution in 2025 is expected to be approximately $53 million for our U.S. and non-U.S. pension plans. This estimate is subject to change, since contribution decisions are affected by various factors including our liquidity, market performance and management’s discretion. The expected future benefit payments, net of participants’ contributions, with respect to the defined benefit pension plans and other postretirement benefit plans, are as follows: Pension Postretirement (in millions) U.S. Plans Non-U.S. Plans U.S. Plans Non-U.S. Plans 2025 $ 261 $ 39 $ 8 $ 1 2026 254 43 7 1 2027 262 44 7 2 2028 255 49 7 2 2029 259 47 7 2 2030-2034 1,138 235 32 9 DEFINED CONTRIBUTION PLANS AIG Parent sponsors several defined contribution plans for U.S. employees that provide for pre-tax salary reduction contributions by employees. The most significant plan is the AIG Incentive Savings Plan (ISP), for which the matching contribution is 100 percent of the first 6% of a participant’s contributions, subject to the IRS-imposed limitations. Participants in the AIG ISP receive an additional fully vested, non-elective, non-discretionary contribution equal to 3% of the participant’s eligible compensation for the plan year, paid each pay period regardless of whether the participant currently contributes to the plan, and subject to the IRS-imposed limitations. Our pre-tax expenses associated with these plans were $87 million,$95 million and $100 million in 2024, 2023 and 2022, respectively.

Income Tax Disclosure [Abstract]
Income Taxes	21. Income Taxes U.S. TAX LAW CHANGES The Inflation Reduction Act of 2022 (H.R. 5376) includes a 15 percent corporate alternative minimum tax (CAMT) on adjusted financial statement income for corporations with average profits over $1 billion over a three-year period. While the U.S. Treasury and Internal Revenue Service (IRS) issued proposed regulations for CAMT during the third quarter of 2024, there are still certain details and specifics of application of the CAMT that remain unclear and we continue to evaluate the impact of the proposed regulations along with prior guidance. BASIS OF PRESENTATION We file a consolidated U.S. federal income tax return with our eligible U.S. subsidiaries. Income earned by subsidiaries operating outside the U.S. is taxed, and income tax expense is recorded, based on applicable U.S. and foreign laws. TAX ACCOUNTING POLICIES We consider our foreign earnings with respect to certain operations in Canada, South Africa, Japan, Latin America, Bermuda as well as the European, Asia Pacific and Middle East regions to be indefinitely reinvested. These earnings relate to ongoing operations and have been reinvested in active business operations. A deferred tax liability has not been recorded for those foreign subsidiaries whose earnings are considered to be indefinitely reinvested. If recorded, such deferred tax liability would not be material to our consolidated financial condition. Deferred taxes, if necessary, have been provided on earnings of non-U.S. affiliates whose earnings are not indefinitely reinvested. Global Intangible Low-Taxed Income (GILTI) imposes U.S. taxes on the excess of a deemed return on tangible assets of certain foreign subsidiaries. Consistent with accounting guidance, we have made an accounting policy election to treat GILTI taxes as a period tax charge in the period the tax is incurred.

(b) Carryforward periods are based on U.S. tax laws governing utilization of tax attributes. Expiration periods are based on the year the carryforward was generated. ASSESSMENT OF DEFERRED TAX ASSET VALUATION ALLOWANCE The evaluation of the recoverability of our deferred tax asset and the need for a valuation allowance requires us to weigh all positive and negative evidence to reach a conclusion that it is more likely than not that all or some portion of the deferred tax asset will not be realized. The weight given to the evidence is commensurate with the extent to which it can be objectively verified. The more negative evidence that exists, the more positive evidence is necessary and the more difficult it is to support a conclusion that a valuation allowance is not needed. During the fourth quarter, taxable income projections were updated to reflect the latest projections of income for our insurance and non-insurance companies, 2024 transactions, and projections of taxable income generated from prudent and feasible tax planning strategies. Given there is a shorter carryforward period to utilize remaining net operating losses, we continue to consider multiple data points and stresses. Additionally, significant market volatility continues to impact actual and projected results of our business operations as well as our views on potential effectiveness of certain prudent and feasible tax planning strategies. In order to demonstrate the predictability and sufficiency of future taxable income necessary to support the realizability of the net operating losses and foreign tax credit carryforwards, we have considered forecasts of future income for each of our businesses, including assumptions about future macroeconomic and AIG-specific conditions and events, and any impact these conditions and events may have on our prudent and feasible tax planning strategies. We also subjected the forecasts to a variety of stresses of key assumptions and evaluated the effect on tax attribute utilization. After factoring in multiple data points and assessing the relative weight of all positive and negative evidence, we concluded that a valuation allowance of $300 million should remain on a portion of AIG's U.S. federal consolidated income tax group tax attribute carryforwards that are not more likely than not to be realized. Accordingly, during the year ended December 31, 2024, we recorded no change in valuation allowance. For the year ended December 31, 2024, recent changes in market conditions, including changes in interest rates, impacted the unrealized tax gains and losses in the available for sale securities portfolios of our general insurance and non-insurance companies, resulting in a decrease to deferred tax assets related to net unrealized tax capital losses. The deferred tax assets relate to the unrealized tax capital losses for which the carryforward period has not yet begun. As of December 31, 2024, based on all available evidence, we concluded that a valuation allowance of $509 million is necessary on deferred tax assets related to unrealized tax capital losses that are not more-likely-than-not to be realized. For the year ended December 31, 2024, we recorded a decrease in valuation allowance of $41 million associated with the unrealized tax capital losses in AIG's available for sale securities portfolio. The valuation allowance decrease was allocated to other comprehensive income. For the year ended December 31, 2024, we recognized a net $31 million decrease in deferred tax asset valuation allowance associated with certain foreign and state jurisdictions. The following table presents the net deferred tax assets (liabilities) at December 31, 2024 and 2023 on a U.S. GAAP basis: December 31, (in millions) 2024 2023 Net U.S. deferred tax assets $ 4,922 $ 5,992 Net deferred tax assets (liabilities) in AOCI 421 509 Valuation allowance (798) (840) Subtotal 4,545 5,661 Net foreign, state and local deferred tax assets 1,263 1,431 Valuation allowance (852) (906) Subtotal 411 525 Subtotal - Net U.S., foreign, state and local deferred tax assets 4,956 6,186 Net foreign, state and local deferred tax liabilities (426) (347) Total AIG net deferred tax assets (liabilities) $ 4,530 $ 5,839 TAX EXAMINATIONS Listed below are the tax years that remain subject to examination by major tax jurisdictions: At December 31, 2024 Open Tax Years Major Tax Jurisdiction United States 2007-2023 Australia 2020-2023 Canada 2020-2023 France 2022-2023 Japan 2018-2023 Korea 2019-2023 Singapore 2020-2023 United Kingdom 2022-2023 ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES The following table presents a reconciliation of the beginning and ending balances of the total amounts of gross unrecognized tax benefits, excluding interest and penalties: Years Ended December 31, (in millions) 2024 2023 2022 Gross unrecognized tax benefits, beginning of year $ 1,387 $ 1,191 $ 1,157 Increases in tax positions for prior years 3 200 29 Decreases in tax positions for prior years (20) (4) (33) Increases in tax positions for current year 15 — 59 Lapse in statute of limitations (1) — (21) Gross unrecognized tax benefits, end of year $ 1,384 $ 1,387 $ 1,191 The activity in unrecognized tax benefits for the year ended December 31, 2023 is primarily attributable to the potential resolution of an IRS audit matter. There was no significant activity in unrecognized tax benefits for the years ended December 31, 2024 and December 31, 2022. At December 31, 2024 and 2023 and 2022, the amounts of unrecognized tax benefits that, if recognized, would favorably affect the effective tax rate were $1.4 billion, $1.4 billion and $1.2 billion, respectively. Unrecognized tax benefits that would not affect the effective tax rate generally relate to such factors as the timing, rather than the permissibility of the deduction. Interest and penalties related to unrecognized tax benefits are recognized in income tax expense. At December 31, 2024, 2023 and 2022, we had accrued liabilities of $53 million, $52 million and $63 million, respectively for the payment of interest (net of the federal benefit) and penalties. For the years ended December 31, 2024, 2023, and 2022, we accrued expense (benefit) of $1 million, $(11) million, and $(2) million, respectively, for the payment of interest and penalties. There was no significant activity in interest and penalties related to unrecognized tax benefit for the years 2024, 2023 or 2022. Although it is reasonably possible that a change in the balance of unrecognized tax benefits may occur within the next 12 months, based on the information currently available, we do not expect any change to be material to our consolidated financial condition.

NOTES TO CONDENSED FINANCIAL INFORMATION OF REGISTRANT American International Group, Inc.’s (the Registrant) investments in consolidated subsidiaries are stated at cost plus equity in undistributed income of consolidated subsidiaries. The accompanying condensed financial statements of the Registrant should be read in conjunction with the consolidated financial statements and notes thereto of American International Group, Inc. and subsidiaries included in the Registrant’s 2024 Annual Report on Form 10-K for the year ended December 31, 2024 (Annual Report on Form 10-K) filed with the Securities and Exchange Commission on February 13, 2025. The Registrant includes in its Statement of Income dividends from its subsidiaries and equity in undistributed income (loss) of consolidated subsidiaries, which represents the net income (loss) of each of its wholly-owned subsidiaries. The five-year debt maturity schedule is incorporated by reference from Note 14 to the Consolidated Financial Statements. On December 14, 2022, AIG announced that its wholly-owned subsidiary, AIG Financial Products Corp. (AIGFP), filed a voluntary petition to reorganize under Chapter 11 of Title 11 of the United States Code in the United States Bankruptcy Court for the District of Delaware and filed a proposed plan of reorganization. The reorganization will not have a material impact on the consolidated balance sheets of AIG or our respective businesses. AIGFP has no material operations or businesses and no employees. In conjunction with the bankruptcy filing, AIGFP and its consolidated subsidiaries were deconsolidated from the results of AIG, resulting in a pre-tax loss of $114 million reported in Net gain (loss) on divestitures and other. The AIGFP loan receivable of $37.6 billion was reclassified to a third party asset, which has a full allowance for credit losses. In addition, AIGFP and its subsidiaries were determined to be an unconsolidated variable interest entity. The Registrant files a consolidated federal income tax return with certain subsidiaries and acts as an agent for the consolidated tax group when making payments to the Internal Revenue Service. The Registrant and its subsidiaries have adopted, pursuant to a written agreement, a method of allocating consolidated Federal income taxes. Amounts allocated to the subsidiaries under the written agreement are included in Due from affiliates in the accompanying Condensed Balance Sheets. Under the U.S. federal tax laws, AIGFP will continue to join in filing of AIG’s consolidated U.S. federal income tax return and AIGFP’s net operating losses continue to be available to offset taxable income of AIG’s consolidated U.S. federal income tax group. Accordingly, deferred tax assets related to AIGFP’s net operating losses remain part of AIG’s deferred tax assets as of December 31, 2024. No additional valuation allowance is required in connection with AIGFP’s reorganization. Income taxes in the accompanying Condensed Balance Sheets are composed of the Registrant’s current and deferred tax assets, the consolidated group’s current income tax receivable and deferred taxes related to tax attribute carryforwards of AIG’s U.S. consolidated federal income tax group. The consolidated U.S. deferred tax asset for net operating loss and tax credit carryforwards are recorded by the Parent Company, which files the consolidated U.S. Federal income tax return, and are not allocated to its subsidiaries. Generally, as, and if, the consolidated net operating losses and other tax attribute carryforwards are utilized, the intercompany tax balance will be settled with the subsidiaries. For additional information, see Note 21 to the Consolidated Financial Statements.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	We maintain a documented Information Security Program (the Program) that is informed by industry standards, frameworks and best practices and is designed to protect the confidentiality, integrity, and availability of our information assets and systems that store, process or transmit information. Our Chief Information Security Officer (CISO) oversees and directs the Program, including implementing adjustments in response to changes in technology, internal and external threats, business processes, and regulatory or statutory requirements and communicates our information security risk posture to senior management and the Board of Directors (the Board). The Program includes the following key elements: • Network, Systems and Data Security – Technical and organizational safeguards that are designed to protect our networks, systems, and data from cybersecurity threats, including firewalls, intrusion prevention and detection systems, anti-malware functionality, and access controls. • Threat and Vulnerability Management – A threat and vulnerability management program that leverages continuous threat intelligence to seek to proactively identify, assess, and mitigate evolving cybersecurity risks. This program incorporates vulnerability scanning, remediation management, bug bounty, penetration testing, and threat response capabilities, all designed to safeguard our information assets and ensure business continuity. • Cybersecurity Incident Monitoring and Response – Incident response plans that address our response to a cybersecurity incident, utilizing a cross-functional approach. • Third-Party Assessment and Oversight – A third-party risk management program designed to identify and manage cybersecurity risks from third-party service providers, including initial due diligence as well as initial and periodic re-assessments of the service provider’s control environment. • Security Training and Awareness – Annual cybersecurity and awareness training for employees and contractors. The Program is evaluated on an ongoing basis, both internally and through third-party audit firms, to address and protect against the evolving cyber threat landscape. The Program seeks to align to industry standards such as the National Institute of Standards and Technology Cybersecurity Framework, as well as applicable legal and regulatory guidance and mandates applicable to all of our stakeholders, including investors, customers, and employees. Control adequacy and design are reviewed at least annually. Independent audits and penetration tests assist in identifying areas for continued focus, improvement and/or inclusion, and are designed to provide assurance that controls are appropriately designed and operating effectively. Additionally, our Internal Audit group performs independent testing of our control environment, including key components of the Program. We also operate a bug bounty program through a crowdsourced security platform to incentivize responsible disclosure of software defects. These independent evaluations help uncover potential security vulnerabilities for remediation by our cybersecurity team.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2024
Accounting Policies [Abstract]
Consolidation	The consolidated financial statements include the accounts of AIG Parent, our controlled subsidiaries (generally through a greater than 50 percent ownership of voting rights and voting interests), and variable interest entities (VIEs) of which we are the primary beneficiary. Equity investments in entities that we do not consolidate, including corporate entities in which we have significant influence and partnership and partnership-like entities in which we have more than minor influence over the operating and financial policies, are accounted for under the equity method unless we have elected the fair value option.
Equity Method Investments	Equity investments in entities that we do not consolidate, including corporate entities in which we have significant influence and partnership and partnership-like entities in which we have more than minor influence over the operating and financial policies, are accounted for under the equity method unless we have elected the fair value option.
Change in Accounting Principle	Prior to the fourth quarter ending December 31, 2022, certain of our foreign property and casualty subsidiaries reported on the basis of a fiscal year ending November 30. The effect on our consolidated financial condition and results of operations of all material events occurring at these subsidiaries from November 30 through December 31 of the periods previously presented in these Consolidated Financial Statements was considered for adjustment and/or disclosure. Effective with the fourth quarter of the year ended December 31, 2022, the foreign property and casualty subsidiaries now report on a calendar year ending December 31. The elimination of a one-month reporting lag of a subsidiary is considered a change in accounting principle. We believe this change in accounting principle is preferable given that it aligns the reporting dates with other consolidated entities, which allows for a timelier and more consistent basis of reporting within our Consolidated Financial Statements. A change in accounting principle requires retrospective application. However, we determined that the effect of not retroactively applying this change was not material to our Consolidated Financial Statements for the current and prior periods. Therefore, we reported the cumulative effect of the change in accounting principle within the Consolidated Statements of Income (Loss) for the year ended December 31, 2022 and did not retrospectively apply the effects of this change to prior periods. The adoption impact was an increase to net income of $100 million for the year ended December 31, 2022.
Basis of Presentation	The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP).
Use of Estimates	USE OF ESTIMATES The preparation of financial statements in accordance with U.S. GAAP requires the application of accounting policies that often involve a significant degree of judgment. Accounting policies that we believe are most dependent on the application of estimates and assumptions are considered our critical accounting estimates and are related to the determination of: • loss reserves; • reinsurance assets, including the allowance for credit losses and disputes; • allowance for credit losses on certain investments, primarily on loans and available for sale fixed maturity securities; • fair value measurements of certain financial assets and financial liabilities; • income taxes, in particular the recoverability of our deferred tax asset and establishment of provisions for uncertain tax positions; and • goodwill impairment.
Premiums	Premiums are presented net of reinsurance, as applicable. Premiums for short-duration contracts are recorded as written on the inception date of the policy. Premiums are earned primarily on a pro rata basis over the term of the related coverage. Sales of extended services contracts are reflected as premiums written and earned on a pro rata basis over the term of the related coverage. In addition, certain miscellaneous income is included as premiums written and earned. The reserve for unearned premiums includes the portion of premiums written relating to the unexpired terms of coverage. Reinsurance premiums are typically earned over the same period as the underlying policies or risks covered by the contract. As a result, the earnings pattern of a reinsurance contract may extend up to 24 months, reflecting the inception dates of the underlying policies throughout the year. Premiums from long-duration life products, other than universal and variable life contracts, are recognized as revenues when due.
Cash	Cash represents cash on hand and demand deposits.
Investments	Short-term investments include interest bearing investments and time deposits. Securities included within short-term investments are stated at estimated fair value. FIXED MATURITY SECURITIES Bonds held to maturity are carried at amortized cost when we have the ability and positive intent to hold these securities until maturity. When we do not have the ability or positive intent to hold bonds until maturity, these securities are classified as available for sale or the fair value option has been elected. None of our fixed maturity securities met the criteria for held to maturity classification at December 31, 2024 or 2023. Unrealized gains and losses from available for sale investments in fixed maturity securities carried at fair value were reported as a separate component of AOCI, net of deferred income taxes, in shareholders’ equity. Realized and unrealized gains and losses from fixed maturity securities for which the fair value option has been elected are reflected in Net investment income. Investments in fixed maturity securities are recorded on a trade-date basis. Interest income is recognized using the effective yield method and reflects amortization of premium and accretion of discount. Premiums and discounts arising from the purchase of bonds classified as available for sale are treated as yield adjustments over their estimated holding periods, until maturity, or call date, if applicable. For investments in certain structured securities, recognized yields are updated based on current information regarding the timing and amount of expected undiscounted future cash flows. For high credit quality structured securities, effective yields are recalculated based on actual payments received and updated prepayment expectations, and the amortized cost is adjusted to the amount that would have existed had the new effective yield been applied since acquisition with a corresponding charge or credit to net investment income. For structured securities that are not high credit quality, the structured securities yields are based on expected cash flows which take into account both expected credit losses and prepayments. An allowance for credit losses is not established upon initial recognition of the asset (unless the security is determined to be a purchased credit deteriorated (PCD) asset which is discussed in more detail below). Subsequently, differences between actual and expected cash flows and changes in expected cash flows are recognized as adjustments to the allowance for credit losses. Changes that cannot be reflected as adjustments to the allowance for credit losses are accounted for as prospective adjustments to yield. Other Invested Assets Carried at Fair Value Certain hedge funds, private equity funds, and other investment partnerships for which we have elected the fair value option are reported at fair value with changes in fair value recognized in Net investment income. Other Invested Assets – Equity Method Investments Other Investments Also included in Other invested assets are real estate held for investment. These investments are reported at cost, less depreciation and are subject to impairment review, as discussed below. Net investment income represents income primarily from the following sources: • Interest income and related expenses, including amortization of premiums and accretion of discounts with changes in the timing and the amount of expected principal and interest cash flows reflected in yield, as applicable. • Dividend income from common and preferred stocks. • Realized and unrealized gains and losses from investments in other securities and investments for which we elected the fair value option. • Earnings from alternative investments. • Net realized gains and losses are determined by specific identification. The net realized gains and losses are generated primarily from the following sources: • Sales of available for sale fixed maturity securities, real estate and other alternative investments. • Reductions to the amortized cost basis of available for sale fixed maturity securities that have been written down due to our intent to sell them or it being more likely than not that we will be required to sell them. • Changes in the allowance for credit losses on bonds available for sale, mortgage and other loans receivable, and loans commitments. • Most changes in the fair value of free standing and embedded derivatives, including changes in the non-performance adjustment are included in Net realized gains (losses). However, changes in derivatives designated as hedging instruments when the fair value of the hedged item is not reported in Net realized gains (losses) are excluded from Net realized gains (losses). • Foreign exchange gains and losses resulting from foreign currency transactions. • Changes in fair value of the embedded derivative related to the Fortitude Re funds withheld assets. EVALUATING INVESTMENTS FOR AN ALLOWANCE FOR CREDIT LOSSES AND IMPAIRMENTS Fixed Maturity Securities If we intend to sell a fixed maturity security or it is more likely than not that we will be required to sell a fixed maturity security before recovery of its amortized cost basis and if the fair value of the security is below amortized cost, an impairment has occurred and the amortized cost is written down to current fair value, with a corresponding charge to Net realized gains (losses). No allowance is established in these situations and any previously recorded allowance is reversed. The new cost basis is not adjusted for subsequent increases in estimated fair value. When assessing our intent to sell a fixed maturity security, or whether it is more likely than not that we will be required to sell a fixed maturity security before recovery of its amortized cost basis, management evaluates relevant facts and circumstances including, but not limited to, decisions to reposition our investment portfolio, sales of securities to meet cash flow needs and sales of securities to take advantage of favorable pricing. For fixed maturity securities for which a decline in the fair value below the amortized cost is due to credit related factors, an allowance is established for the difference between the estimated recoverable value and amortized cost with a corresponding charge to Net realized gains (losses). The allowance for credit losses is limited to the difference between amortized cost and fair value. The estimated recoverable value is the present value of cash flows expected to be collected, as determined by management. The difference between fair value and amortized cost that is not associated with credit related factors is presented in unrealized appreciation (depreciation) of fixed maturity securities on which an allowance for credit losses was previously recognized (a separate component of AOCI). Accrued interest is excluded from the measurement of the allowance for credit losses. When estimating future cash flows for structured fixed maturity securities (e.g., RMBS, CMBS, CLO, ABS) management considers the historical performance of underlying assets and available market information as well as bond-specific structural considerations, such as credit enhancement and the priority of payment structure of the security. In addition, the process of estimating future cash flows includes, but is not limited to, the following critical inputs, which vary by asset class: • Current delinquency rates; • Expected default rates and the timing of such defaults; • Loss severity and the timing of any recovery; and • Expected prepayment speeds. When estimating future cash flows for corporate, municipal and sovereign fixed maturity securities determined to be credit impaired, management considers: • Expected default rates and the timing of such defaults; • Loss severity and the timing of any recovery; and • Scenarios specific to the issuer and the security, which may also include estimates of outcomes of corporate restructurings, political and macroeconomic factors, stability and financial strength of the issuer, the value of any secondary sources of repayment and the disposition of assets. We consider severe price declines in our assessment of potential credit impairments. We may also modify our model inputs when we determine that price movements in certain sectors are indicative of factors not captured by the cash flow models. Under the current expected credit loss (CECL) model, credit losses are reassessed each period. The allowance for credit losses and the corresponding charge to Net realized gains (losses) can be reversed if conditions change, however, the allowance for credit losses will never be reduced below zero. When we determine that all or a portion of a fixed maturity security is uncollectable, the uncollectable amortized cost amount is written off with a corresponding reduction to the allowance for credit losses. If we collect cash flows that were previously written off, the recovery is recognized by recording a gain in Net realized gains (losses). We purchase certain RMBS securities that have experienced more-than-insignificant deterioration in credit quality since origination. These are referred to as PCD assets. At the time of purchase an allowance is recognized for these PCD assets by adding it to the purchase price to arrive at the initial amortized cost. There is no credit loss expense recognized upon acquisition of a PCD asset. When determining the initial allowance for credit losses, management considers the historical performance of underlying assets and available market information as well as bond-specific structural considerations, such as credit enhancement and the priority of payment structure of the security. In addition, the process of estimating future cash flows includes, but is not limited to, the following critical inputs: • Current delinquency rates; • Expected default rates and the timing of such defaults; • Loss severity and the timing of any recovery; and • Expected prepayment speeds. Subsequent to the acquisition date, the PCD assets follow the same accounting as other structured securities that are not high credit quality. Other Invested Assets Our equity method investments in private equity funds, hedge funds and other entities are evaluated for impairment each reporting period. Such evaluation considers market conditions, events and volatility that may impact the recoverability of the underlying investments within these private equity funds and hedge funds and is based on the nature of the underlying investments and specific inherent risks. Such risks may evolve based on the nature of the underlying investments. Our investments in real estate are periodically evaluated for recoverability whenever changes in circumstances indicate the carrying amount of an asset may be impaired. When impairment indicators are present, we compare expected investment cash flows to carrying amount. When the expected cash flows are less than the carrying amount, the investments are written down to fair value with a corresponding charge to earnings. Secured Financing and Similar Arrangements We enter into secured financing transactions whereby certain securities are sold under agreements to repurchase (repurchase agreements), in which we transfer securities in exchange for cash, with an agreement by us to repurchase the same or substantially similar securities. Our secured financing transactions also include those that involve the transfer of securities to financial institutions in exchange for cash (securities lending agreements). In all of these secured financing transactions, the securities transferred by us (pledged collateral) may be sold or repledged by the counterparties. These agreements are recorded at their contracted amounts plus accrued interest, other than those that are accounted for at fair value. Pledged collateral levels are monitored daily and are generally maintained at an agreed-upon percentage of the fair value of the amounts borrowed during the life of the transactions. In the event of a decline in the fair value of the pledged collateral under these secured financing transactions, we may be required to transfer cash or additional securities as pledged collateral under these agreements. At the termination of the transactions, we and our counterparties are obligated to return the amounts borrowed and the securities transferred, respectively. We also enter into agreements in which securities are purchased by us under reverse repurchase agreements, which are accounted for as secured financing transactions and reported as short-term investments or other assets, depending on their terms. These agreements are recorded at their contracted resale amounts plus accrued interest, other than those that are accounted for at fair value. In all reverse repurchase transactions, we take possession of or obtain a security interest in the related securities, and we have the right to sell or repledge this collateral received.
Premiums and Other Receivables - Net of Allowance for Credit Losses and Disputes	Premiums and other receivables – net of allowance for credit losses and disputes include premium balances receivable, amounts due from agents and brokers and policyholders, receivables resulting from sales of securities that had not yet settled, cash collateral posted to derivative counterparties that is not eligible to be netted against derivative liabilities and other receivables.
Deposit Assets and Liabilities	Deposit assets and liabilities We have entered into certain insurance and reinsurance contracts that do not contain sufficient insurance risk to be accounted for as insurance or reinsurance. When we receive premiums on such contracts, the premiums received, after deduction for certain related expenses, are recorded as deposits within Deposit accounting liabilities in the Consolidated Balance Sheets. Net proceeds of these deposits are invested and generate Net investment income. When we pay premiums on such contracts, the premiums paid are recorded as deposits within Deposit accounting assets in the Consolidated Balance Sheets. The deposit asset or liability is adjusted as amounts are paid, consistent with the underlying contracts. Deferred gains on retroactive reinsurance agreements are also reflected within deposit accounting liabilities.
Other Assets	Other assets consist of prepaid expenses, deposits, other deferred charges, real estate, other fixed assets, capitalized software costs, goodwill, intangible assets other than goodwill, restricted cash, derivative assets, and accrued interest income.
Other Liabilities	Other liabilities consist of other funds on deposit, other payables, securities sold under agreements to repurchase, securities sold but not yet purchased, liabilities resulting from purchases of securities that have not yet settled, derivative liabilities, cash collateral received from derivative counterparties that contractually cannot be netted against derivative assets and allowance for credit losses in relation to off-balance sheet commitments.
Foreign Currency	Foreign currency Financial statement accounts expressed in foreign currencies are translated into U.S. dollars. Functional currency assets and liabilities are translated into U.S. dollars generally using rates of exchange prevailing at the balance sheet date of each respective subsidiary and the related translation adjustments are recorded as a separate component of Accumulated other comprehensive income, net of any related taxes, in Total AIG shareholders’ equity. Income statement accounts expressed in functional currencies are translated using average exchange rates during the period. Functional currencies are generally the currencies of the local operating environment. Financial statement accounts expressed in currencies other than the functional currency of a consolidated entity are remeasured into that entity’s functional currency resulting in exchange gains or losses recorded in income. The adjustments resulting from translation of financial statements of foreign entities operating in highly inflationary economies are recorded in income.
Non-Redeemable Noncontrolling Interest	Non-redeemable noncontrolling interest is the portion of equity (net assets) and net income (loss) in a subsidiary not attributable, directly or indirectly, to AIG.
Accounting Standards Adopted During 2024 and Future Application of Accounting Standards	ACCOUNTING STANDARDS ADOPTED DURING 2024 Fair Value Measurement On June 30, 2022, the Financial Accounting Standards Board (FASB) issued an accounting standards update to address diversity in practice by clarifying that a contractual sale restriction should not be considered in the measurement of the fair value of an equity security. It also requires entities with investments in equity securities subject to contractual sale restrictions to disclose certain qualitative and quantitative information about such securities. The Company adopted the standard on January 1, 2024, prospectively for entities other than investment companies. The adoption of the standard did not have a material impact on AIG Consolidated Financial Statements. Segment Reporting In November 2023, the FASB issued an accounting standard update to address improvements to reportable segment disclosures. The standard primarily requires the following disclosure on an annual and interim basis: (i) significant segment expenses that are regularly provided to the chief operating decision makers (CODMs) and included within each reported measure of segment profit or loss; and (ii) other segment items and description of its composition. The standard also requires current annual disclosures about a reportable segment's profits or losses and assets to be disclosed in interim periods and the title and position of the CODMs with an explanation of how the CODMs uses the reported measure(s) of segment profits or losses in assessing segment performance. The Company adopted the standard for its 2024 Annual Report on Form 10-K, retrospectively. For additional detail, see Note 3 FUTURE APPLICATION OF ACCOUNTING STANDARDS Income Tax In December 2023, the FASB issued an accounting standard update to address improvements to income tax disclosures. The standard requires disaggregated information about a company’s effective tax rate reconciliation as well as information on income taxes paid. The standard is effective for public companies for annual periods beginning after December 15, 2024, with early adoption permitted. The standard should be applied on a prospective basis, but retrospective application is permitted. We are assessing the impact of this standard. Disaggregation of Income Statement Expenses
Segment Information	In the fourth quarter of 2024, the Company realigned its organizational structure and the composition of its reportable segments to reflect changes in how the Company manages its operations, specifically the level at which its chief operating decision makers (CODMs) regularly review operating results and allocate resources. Our CODMs are the chief executive officer (CEO) and chief financial officer (CFO). The CODMs evaluate performance of the segments based on underwriting income (loss). The CODMs use this measure to benchmark AIG’s performance, assessing performance of the segments and in establishing management’s compensation. AIG has three reportable segments: North America Commercial, International Commercial and Global Personal. Prior years’ presentations have been recast to conform to the new reportable segments. Our General Insurance business (General Insurance) consists of our three segments and the Net investment income related to our insurance operations. NORTH AMERICA COMMERCIAL North America Commercial consists of insurance businesses in the United States, Canada and Bermuda. INTERNATIONAL COMMERCIAL International Commercial consists of insurance businesses in Japan, the United Kingdom, Europe, Middle East and Africa (EMEA region), Asia Pacific, Latin America and Caribbean, and China. International also includes the results of Talbot Underwriting Ltd. as well as AIG’s Global Specialty business. GLOBAL PERSONAL Global Personal consists primarily of insurance businesses in the United States as well as Japan, the United Kingdom, Europe, Middle East and Africa (EMEA region), Asia Pacific, Latin America and Caribbean, and China. PRODUCTS The segments consist of the following products: – North America and International Commercial consists of Property & Short Tail, Casualty, Financial Lines and Global Specialty. – Global Personal consists of Global Accident & Health and Personal Lines. For further discussion on recent activity in the General Insurance business, see Note 1. OTHER OPERATIONS Other Operations predominantly consists of Net Investment Income from our AIG Parent liquidity portfolio, Corebridge dividend income, corporate General operating expenses, and Interest expense. SEGMENT RESULTS
Discontinued Operations Presentation	We present a business, or a component of an entity, as discontinued operations if a) it meets the held-for-sale criteria, or is disposed of by sale, or is disposed of other than by sale, and b) the disposal of the business, or component of an entity, represents a strategic shift that has (or will have) a major effect on AIG’s financial results. Subsequent to the Deconsolidation Date, AIG elected the fair value option and reflects its retained interest in Corebridge as an equity method investment in Other invested assets using Corebridge’s stock price as its fair value. Dividends received from Corebridge and changes in its stock price are recognized in Net investment income.
Fair Value Measurements	We carry certain of our financial instruments at fair value. We define the fair value of a financial instrument as the amount that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We are responsible for the determination of the value of the investments carried at fair value and the supporting methodologies and assumptions. The degree of judgment used in measuring the fair value of financial instruments generally inversely correlates with the level of observable valuation inputs. We maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Financial instruments with quoted prices in active markets generally have more pricing observability and less judgment is used in measuring fair value. Conversely, financial instruments for which no quoted prices are available have less observability and are measured at fair value using valuation models or other pricing techniques that require more judgment. Pricing observability is affected by a number of factors, including the type of financial instrument, whether the financial instrument is new to the market and not yet established, the characteristics specific to the transaction, liquidity and general market conditions. Fair Value Hierarchy Assets and liabilities recorded at fair value in the Consolidated Balance Sheets are measured and classified in accordance with a fair value hierarchy consisting of three “levels” based on the observability of valuation inputs: • Level 1: Fair value measurements based on quoted prices (unadjusted) in active markets that we have the ability to access for identical assets or liabilities. Market price data generally is obtained from exchange or dealer markets. We do not adjust the quoted price for such instruments. • Level 2: Fair value measurements based on inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. • Level 3: Fair value measurements based on valuation techniques that use significant inputs that are unobservable. Both observable and unobservable inputs may be used to determine the fair values of positions classified in Level 3. The circumstances for using these measurements include those in which there is little, if any, market activity for the asset or liability. Therefore, we must make certain assumptions about the inputs a hypothetical market participant would use to value that asset or liability. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The following is a description of the valuation methodologies used for instruments carried at fair value. These methodologies are applied to assets and liabilities across the levels discussed above, and the observability of the inputs used determines the appropriate level in the fair value hierarchy for the respective asset or liability. VALUATION METHODOLOGIES OF FINANCIAL INSTRUMENTS MEASURED AT FAIR VALUE Incorporation of Credit Risk in Fair Value Measurements • Our Own Credit Risk. Fair value measurements for certain liabilities incorporate our own credit risk by determining the explicit cost for each counterparty to protect against its net credit exposure to us at the balance sheet date by reference to observable AIG credit default swaps (CDS) or cash bond spreads. We calculate the effect of credit spread changes using discounted cash flow techniques that incorporate current market interest rates. A derivative counterparty’s net credit exposure to us is determined based on master netting agreements, when applicable, which take into consideration all derivative positions with us, as well as collateral we post with the counterparty at the balance sheet date. • Counterparty Credit Risk. Fair value measurements for freestanding derivatives incorporate counterparty credit by determining the explicit cost for us to protect against our net credit exposure to each counterparty at the balance sheet date by reference to observable counterparty CDS spreads, when available. When not available, other directly or indirectly observable credit spreads will be used to derive the best estimates of the counterparty spreads. Our net credit exposure to a counterparty is determined based on master netting agreements, which take into consideration all derivative positions with the counterparty, as well as collateral posted by the counterparty at the balance sheet date. Fair values for fixed maturity securities based on observable market prices for identical or similar instruments implicitly incorporate counterparty credit risk. Fair values for fixed maturity securities based on internal models incorporate counterparty credit risk by using discount rates that take into consideration cash issuance spreads for similar instruments or other observable information. For fair values measured based on internal models, the cost of credit protection is determined under a discounted present value approach considering the market levels for single name CDS spreads for each specific counterparty, the mid-market value of the net exposure (reflecting the amount of protection required) and the weighted average life of the net exposure. CDS spreads are provided to us by an independent third party. We utilize an interest rate based on the appropriate benchmark curve to derive our discount rates. While this approach does not explicitly consider all potential future behavior of the derivative transactions or potential future changes in valuation inputs, we believe this approach provides a reasonable estimate of the fair value of the assets and liabilities, including consideration of the impact of non-performance risk. Fixed Maturity Securities Whenever available, we obtain quoted prices in active markets for identical assets at the balance sheet date to measure fixed maturity securities at fair value. Market price data is generally obtained from dealer markets. We employ independent third-party valuation service providers to gather, analyze, and interpret market information to derive fair value estimates for individual investments, based upon market-accepted methodologies and assumptions. The methodologies used by these independent third-party valuation service providers are reviewed and understood by management, through periodic discussion with and information provided by the independent third-party valuation service providers. In addition, as discussed further below, control processes designed to ensure the accuracy of these values are applied to the fair values received from independent third-party valuation service providers. Valuation service providers typically obtain data about market transactions and other key valuation model inputs from multiple sources and, through the use of market-accepted valuation methodologies, which may utilize matrix pricing, financial models, accompanying model inputs and various assumptions, provide a single fair value measurement for individual securities. The inputs used by the valuation service providers include, but are not limited to, market prices from completed transactions for identical securities and transactions for comparable securities, benchmark yields, interest rate yield curves, credit spreads, prepayment rates, default rates, recovery assumptions, currency rates, quoted prices for similar securities and other market-observable information, as applicable. If fair value is determined using financial models, these models generally take into account, among other things, market observable information as of the measurement date as well as the specific attributes of the security being valued, including its term, interest rate, credit rating, industry sector, and when applicable, collateral quality and other security or issuer-specific information. When market transactions or other market observable data is limited, the extent to which judgment is applied in determining fair value is greatly increased. We have control processes designed to ensure that the fair values received from independent third-party valuation service providers are accurately recorded, that their data inputs and valuation techniques are appropriate and consistently applied and that the assumptions used appear reasonable and consistent with the objective of determining fair value. We assess the reasonableness of individual security values received from independent third-party valuation service providers through various analytical techniques, and have procedures to escalate related questions internally and to the independent third-party valuation service providers for resolution. To assess the degree of pricing consensus among various valuation service providers for specific asset types, we conduct comparisons of prices received from available sources. We use these comparisons to establish a hierarchy for the fair values received from independent third-party valuation service providers to be used for particular security classes. We also validate prices for selected securities through reviews by members of management who have relevant expertise and who are independent of those charged with executing investing transactions. When our independent third-party valuation service providers are unable to obtain sufficient market observable information upon which to estimate the fair value for a particular security, fair value is determined either by requesting brokers who are knowledgeable about these securities to provide a price quote, which is generally non-binding, or by employing market accepted valuation models internally or via our third party asset managers. Broker prices may be based on an income approach, which converts expected future cash flows to a single present value amount, with specific consideration of inputs relevant to particular security types. For structured securities, such inputs may include ratings, collateral types, geographic concentrations, underlying loan vintages, loan delinquencies and defaults, loss severity assumptions, prepayments, and weighted average coupons and maturities. When the volume or level of market activity for a security is limited, certain inputs used to determine fair value may not be observable in the market. Broker prices may also be based on a market approach that considers recent transactions involving identical or similar securities. Fair values provided by brokers are subject to similar control processes to those noted above for fair values from independent third-party valuation service providers, including management reviews. For those corporate debt instruments (for example, private placements) that are not traded in active markets or that are subject to transfer restrictions, valuations reflect illiquidity and non-transferability, based on available market evidence. When observable price quotations are not available, fair value is determined based on discounted cash flow models using discount rates based on credit spreads, yields or price levels of comparable securities, adjusted for illiquidity and structure. Fair values determined internally or via our third party asset managers are also subject to management review to ensure that valuation models and related inputs are reasonable. The methodology above is relevant for all fixed maturity securities including residential mortgage backed securities (RMBS), commercial mortgage backed securities (CMBS), collateralized loan obligations (CLO), other asset‑backed securities (ABS) and fixed maturity securities issued by government sponsored entities and corporate entities. Equity Securities Traded in Active Markets Whenever available, we obtain quoted prices in active markets for identical assets at the balance sheet date to measure equity securities at fair value. Market price data is generally obtained from exchange or dealer markets. Mortgage and Other Loans Receivable We estimate the fair value of mortgage and other loans receivable that are measured at fair value by using dealer quotations, discounted cash flow analyses and/or internal valuation models. The determination of fair value considers inputs such as interest rate, maturity, the borrower’s creditworthiness, collateral, subordination, guarantees, past-due status, yield curves, credit curves, prepayment rates, market pricing for comparable loans and other relevant factors. Other Invested Assets We initially estimate the fair value of investments in certain hedge funds, private equity funds and other investment partnerships by reference to the transaction price. Subsequently, we generally obtain the fair value of these investments from net asset value information provided by the general partner or manager of the investments, the financial statements of which are generally audited annually. We consider observable market data and perform certain control procedures to validate the appropriateness of using the net asset value as a fair value measurement. The fair values of other investments carried at fair value, such as direct private equity holdings, are initially determined based on transaction price and are subsequently estimated based on available evidence such as market transactions in similar instruments, other financing transactions of the issuer and other available financial information for the issuer, with adjustments made to reflect illiquidity as appropriate. AIG's retained investments in Corebridge, for which we have elected the fair value option, is determined using Corebridge's stock price as its fair value. Short-term Investments For short-term investments that are measured at amortized cost, the carrying amounts of these assets approximate fair values because of the relatively short period of time between origination and expected realization, and their limited exposure to credit risk. Securities purchased under agreements to resell (reverse repurchase agreements) are generally treated as collateralized receivables. We report certain receivables arising from securities purchased under agreements to resell as Short-term investments in the Consolidated Balance Sheets. When these receivables are measured at fair value, we use market-observable interest rates to determine fair value. Freestanding Derivatives Derivative assets and liabilities can be exchange-traded or traded over-the-counter (OTC). We generally value exchange-traded derivatives such as futures and options using quoted prices in active markets for identical derivatives at the balance sheet date. OTC derivatives are valued using market transactions and other market evidence whenever possible, including market-based inputs to models, model calibration to market clearing transactions, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency. When models are used, the selection of a particular model to value an OTC derivative depends on the contractual terms of, and specific risks inherent in the instrument, as well as the availability of pricing information in the market. We generally use similar models to value similar instruments. Valuation models require a variety of inputs, including contractual terms, market prices and rates, yield curves, credit curves, measures of volatility, prepayment rates and correlations of such inputs. For OTC derivatives that trade in liquid markets, such as generic forwards, swaps and options, model inputs can generally be corroborated by observable market data by correlation or other means, and model selection does not involve significant management judgment. For certain OTC derivatives that trade in less liquid markets, where we generally do not have corroborating market evidence to support significant model inputs and cannot verify the model to market transactions, the transaction price may provide the best estimate of fair value. Accordingly, when a pricing model is used to value such an instrument, the model is adjusted so the model value at inception equals the transaction price. We will update valuation inputs in these models only when corroborated by evidence such as similar market transactions, independent third-party valuation service providers and/or broker or dealer quotations, or other empirical market data. When appropriate, valuations are adjusted for various factors such as liquidity, bid/offer spreads and credit considerations. Such adjustments are generally based on available market evidence. In the absence of such evidence, management’s best estimate is used. We value our super senior credit default swap portfolio using prices obtained from vendors and/or counterparties. The valuation of the super senior credit derivatives is complex because of the limited availability of market observable information due to the lack of trading and price transparency in certain structured finance markets. Our valuation methodologies for the super senior CDS portfolio have evolved over time in response to market conditions and the availability of market observable information. We have sought to calibrate the methodologies to available market information and to review the assumptions of the methodologies on a regular basis. Fortitude Re funds withheld payable The reinsurance transactions between AIG and Fortitude Re were structured as modco and loss portfolio transfer arrangements with funds withheld (funds withheld). AIG has established a funds withheld payable to Fortitude Re while simultaneously establishing a reinsurance asset representing reserves for the insurance coverage that Fortitude Re has assumed. The funds withheld payable contains an embedded derivative and changes in fair value of the embedded derivative related to the funds withheld payable are recognized in earnings through realized gains (losses). This embedded derivative is considered a total return swap with contractual returns that are attributable to various assets and liabilities associated with these reinsurance agreements. Other Liabilities Other liabilities measured at fair value include certain securities sold under agreements to repurchase and certain securities sold but not yet purchased. Liabilities arising from securities sold under agreements to repurchase are generally treated as collateralized borrowings. We estimate the fair value of liabilities arising under these agreements by using market-observable interest rates. This methodology considers such factors as the coupon rate, yield curves and other relevant factors. Fair values for securities sold but not yet purchased are based on current market prices. We consider unobservable inputs to be those for which market data is not available and that are developed using the best information available to us about the assumptions that market participants would use when pricing the asset or liability. Relevant inputs vary depending on the nature of the instrument being measured at fair value. The following paragraphs provide a general description of significant unobservable inputs along with interrelationships between and among the significant unobservable inputs and their impact on the fair value measurements. In practice, simultaneous changes in assumptions may not always have a linear effect on the inputs discussed below. Interrelationships may also exist between observable and unobservable inputs. Such relationships have not been included in the discussion below. For each of the individual relationships described below, the inverse relationship would also generally apply. Fixed Maturity Securities The significant unobservable input used in the fair value measurement of fixed maturity securities is yield. The yield is affected by the market movements in credit spreads and U.S. Treasury yields. The yield may be affected by other factors including constant prepayment rates, loss severity, and constant default rates. In general, increases in the yield would decrease the fair value of investments, and conversely, decreases in the yield would increase the fair value of investments. Embedded Derivatives within Reinsurance Contracts The fair value of embedded derivatives associated with funds withheld reinsurance contracts is determined based upon a total return swap technique with reference to the fair value of the investments held by AIG related to AIG’s funds withheld payable. The fair value of the underlying assets is generally based on market observable inputs using industry standard valuation techniques. The valuation also requires certain significant inputs, which are generally not observable, and accordingly, the valuation is considered Level 3 in the fair value hierarchy. Under the fair value option, we may elect to measure at fair value financial assets and financial liabilities that are not otherwise required to be carried at fair value. Subsequent changes in fair value for designated items are reported in earnings. We elect the fair value option for certain hybrid securities given the complexity of bifurcating the economic components associated with the embedded derivatives. Additionally, we elect the fair value option for certain alternative investments when such investments are eligible for this election. We believe this measurement basis is consistent with the applicable accounting guidance used by the respective investment company funds themselves. Interest income and dividend income on assets measured under the fair value option are recognized and included in Net investment income in the Consolidated Statements of Income. Interest expense on liabilities measured under the fair value option is reported in Other Income in the Consolidated Statements of Income. We calculate the effect of these credit spread changes using discounted cash flow techniques that incorporate current market interest rates, our observable credit spreads on these liabilities and other factors that mitigate the risk of nonperformance such as cash collateral posted. Information regarding the estimation of fair value for financial instruments not carried at fair value (excluding insurance contracts and lease contracts) is discussed below: • Mortgage and other loans receivable: Fair values of loans on commercial real estate and other loans receivable are estimated for disclosure purposes using discounted cash flow calculations based on discount rates that we believe market participants would use in determining the price that they would pay for such assets. For certain loans, our current incremental lending rates for similar types of loans are used as the discount rates, because we believe this rate approximates the rates market participants would use. Fair values of residential mortgage loans are generally determined based on market prices, using market based adjustments for credit and servicing as appropriate. The fair values of policy loans are generally estimated based on unpaid principal amount as of each reporting date. No consideration is given to credit risk because policy loans are effectively collateralized by the cash surrender value of the policies. • Other invested assets: The majority of the Other invested assets that are not measured at fair value represent time deposits with the original maturity at purchase greater than one year. The fair value of long-term time deposits is determined using the expected discounted future cash flow. • Cash and short-term investments: The carrying amounts of these assets approximate fair values because of the relatively short period of time between origination and expected realization, and their limited exposure to credit risk. • Other liabilities: The majority of Other liabilities that are financial instruments not measured at fair value represent secured financing arrangements, including repurchase agreements. The carrying amounts of these liabilities approximate fair value, because the financing arrangements are short-term and are secured by cash or other liquid collateral. • Fortitude Re funds withheld payable: The funds withheld payable contains an embedded derivative and the changes in its fair value are recognized in earnings each period. The difference between the total Fortitude Re funds withheld payable and the embedded derivative represents the host contract. • Long-term debt and Debt of consolidated investment entities: Fair values of these obligations were determined by reference to quoted market prices, when available and appropriate, or discounted cash flow calculations based upon our current market‑observable implicit‑credit‑spread rates for similar types of borrowings with maturities consistent with those remaining for the debt being valued.
Lending Activities	Mortgage and other loans receivable include commercial mortgages, life insurance policy loans, commercial loans, and other loans and notes receivable. Commercial mortgages, commercial loans, and other loans and notes receivable are carried at unpaid principal balances less allowance for credit losses and plus or minus adjustments for the accretion or amortization of discount or premium. Interest income on such loans is accrued as earned. Direct costs of originating commercial mortgages, commercial loans, and other loans and notes receivable, net of nonrefundable points and fees, are deferred and included in the carrying amount of the related receivables. The amount deferred is amortized to income as an adjustment to earnings using the interest method. Life insurance policy loans are carried at unpaid principal balances. There is no allowance for policy loans because these loans serve to reduce the death benefit paid when the death claim is made and the balances are effectively collateralized by the cash surrender value of the policy.
Lending Activities, Interest Income	Interest income is not accrued when payment of contractual principal and interest is not expected. Any cash received on impaired loans is generally recorded as a reduction of the current carrying amount of the loan. Accrual of interest income is generally resumed when delinquent contractual principal and interest is repaid or when a portion of the delinquent contractual payments are made and the ongoing required contractual payments have been made for an appropriate period.
Credit Losses	At the time of origination or purchase, an allowance for credit losses is established for mortgage and other loan receivables and is updated each reporting period. Changes in the allowance for credit losses are recorded in realized losses. This allowance reflects the risk of loss, even when that risk is remote, that is expected over the remaining contractual life of the loan. The allowance for credit losses considers available relevant information about the collectability of cash flows, including information about past events, current conditions, and reasonable and supportable forecasts of future economic conditions. We revert to historical information when we determine that we can no longer reliably forecast future economic assumptions. The allowances for the commercial mortgage loans are estimated utilizing a probability of default and loss given default model. Loss rate factors are determined based on historical data and adjusted for current and forecasted information. The loss rates are applied based on individual loan attributes and considering such data points as loan-to-value ratios, Fair Isaac Corporation scores, and debt service coverage. The estimate of credit losses also reflects management’s assumptions on certain macroeconomic factors that include, but are not limited to, gross domestic product growth, employment, inflation, housing price index, interest rates and credit spreads. Accrued interest is excluded from the measurement of the allowance for credit losses and accrued interest is reversed through interest income once a loan is placed on nonaccrual. When all or a portion of a loan is deemed uncollectible, the uncollectible portion of the carrying amount of the loan is charged off against the allowance. We also have off-balance sheet commitments related to our commercial mortgage loans. The liability for expected credit losses related to these commercial mortgage loan commitments is reported in Other liabilities in the Consolidated Balance Sheets. When a commitment is funded, we record a loan receivable and reclassify the liability for expected credit losses related to the commitment into loan allowance for expected credit losses. Other changes in the liability for expected credit losses on loan commitments are recorded in Net realized gains (losses) in the Consolidated Statements of Income (Loss). LOAN MODIFICATIONS The allowance for credit losses incorporates an estimate of lifetime expected credit losses and is recorded on each asset upon asset origination or acquisition. The starting point for the estimate of the allowance for credit losses is historical loss information, which includes losses from modifications of receivables to borrowers experiencing financial difficulty. We use a probability of default/loss given default model to determine the allowance for credit losses for our commercial mortgage loans. An assessment of whether a borrower is experiencing financial difficulty is made on the date of a modification. Because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses utilizing the measurement methodologies used to estimate the allowance, a change to the allowance for credit losses is generally not recorded upon modification. When modifications are executed, they often will be in the form of principal forgiveness, term extensions, interest rate reductions, or some combination of any of these concessions. When principal is forgiven, the amortized cost basis of the asset is written off against the allowance for credit losses. The amount of the principal forgiveness is deemed to be uncollectible; therefore, that portion of the loan is written off, resulting in a reduction of the amortized cost basis and a corresponding adjustment to the allowance for credit losses. We assess whether a borrower is experiencing financial difficulty based on a variety of factors, including the borrower’s current default on any of its outstanding debt, the probability of a default on any of its debt in the foreseeable future without the modification, the insufficiency of the borrower’s forecasted cash flows to service any of its outstanding debt (including both principal and interest), and the borrower’s inability to access alternative third party financing at an interest rate that would be reflective of current market conditions for a non-troubled debtor. Reinsurance assets include the balances due for paid losses and expenses, reserves for losses and expenses reported and outstanding, reserves for IBNR, ceded unearned premiums and ceded future policy benefits for life and accident and health insurance contracts and benefits paid and unpaid. Amounts related to paid and reserved losses and expenses and benefits with respect to these reinsurance agreements are sometimes collateralized. We remain liable to our policyholders regardless of whether our reinsurers meet their obligations under the reinsurance contracts, and as such, we regularly evaluate the financial condition of our reinsurers and monitor concentration of our credit risk. The estimation of the allowance for unrecoverable reinsurance from reinsurers who are unwilling and/or unable to pay amounts due to us requires judgment for which key inputs typically include historical collection rates when amounts due are in dispute or where the reinsurer has suffered a credit event as well as specific reviews of balances in dispute or subject to credit impairment. The allowance for credit losses and disputes on reinsurance assets was $220 million and $206 million at December 31, 2024 and 2023, respectively. Changes in the allowance for credit losses and disputes on reinsurance assets are reflected in Losses and loss adjustment expenses incurred within the Consolidated Statements of Income (Loss). REINSURANCE – CREDIT LOSSES The estimation of reinsurance recoverables involves a significant amount of judgment, particularly for latent exposures, such as asbestos, due to their long-tail nature. We assess the collectability of reinsurance recoverable balances in each reporting period, through either historical trends of disputes and credit events or financial analysis of the credit quality of the reinsurer. We record adjustments to reflect the results of these assessments through an allowance for credit losses and disputes on uncollectible reinsurance that reduces the carrying amount of reinsurance and deposit accounting assets on the consolidated balance sheets (collectively, reinsurance recoverables). This estimate requires significant judgment for which key considerations include: • paid and unpaid amounts recoverable; • whether the balance is in dispute or subject to legal collection; • the relative financial health of the reinsurer as classified by the Obligor Risk Ratings (ORRs) we assign to each reinsurer based upon our financial reviews; reinsurers that are financially troubled (i.e., in run-off, have voluntarily or involuntarily been placed in receivership, are insolvent, are in the process of liquidation or otherwise subject to formal or informal regulatory restriction) are assigned ORRs that will generate a significant allowance; and • whether collateral and collateral arrangements exist. An estimate of the reinsurance recoverable's lifetime expected credit losses is established utilizing a probability of default and loss given default method, which reflects the reinsurer’s ORR. The allowance for credit losses excludes disputed amounts. An allowance for disputes is established for a reinsurance recoverable using the losses incurred model for contingencies.
Reinsurance	We determine the portion of our ultimate net loss that will be recoverable under our reinsurance contracts by reference to the terms of the reinsurance protection purchased. This determination involves an estimate of incurred but not reported (IBNR) loss. Reinsurance recoverables for contracts which are accounted for as deposits are subject to similar judgments and uncertainties and reported in Deposit accounting assets. Reinsurance assets include the balances due for paid losses and expenses, reserves for losses and expenses reported and outstanding, reserves for IBNR, ceded unearned premiums and ceded future policy benefits for life and accident and health insurance contracts and benefits paid and unpaid. Amounts related to paid and reserved losses and expenses and benefits with respect to these reinsurance agreements are sometimes collateralized. We remain liable to our policyholders regardless of whether our reinsurers meet their obligations under the reinsurance contracts, and as such, we regularly evaluate the financial condition of our reinsurers and monitor concentration of our credit risk. The estimation of the allowance for unrecoverable reinsurance from reinsurers who are unwilling and/or unable to pay amounts due to us requires judgment for which key inputs typically include historical collection rates when amounts due are in dispute or where the reinsurer has suffered a credit event as well as specific reviews of balances in dispute or subject to credit impairment. The allowance for credit losses and disputes on reinsurance assets was $220 million and $206 million at December 31, 2024 and 2023, respectively. Changes in the allowance for credit losses and disputes on reinsurance assets are reflected in Losses and loss adjustment expenses incurred within the Consolidated Statements of Income (Loss). SHORT-DURATION REINSURANCE Short-duration reinsurance is effected under reinsurance treaties and by negotiation on individual risks. Certain of these reinsurance arrangements consist of excess of loss contracts that protect us against losses above stipulated amounts. Ceded premiums are considered prepaid reinsurance premiums and are recognized as a reduction of premiums earned over the contract period in proportion to the protection received. Amounts recoverable from reinsurers on short-duration contracts are estimated in a manner consistent with the claims liabilities associated with the reinsurance and presented as a component of Reinsurance assets. Reinsurance premiums for assumed business are estimated based on information received from brokers, ceding companies and reinsurers. Any subsequent differences arising on such estimates are recorded in the periods in which they are determined. Assumed reinsurance premiums are earned primarily on a pro-rata basis over the terms of the reinsurance contracts and the portion of premiums relating to the unexpired terms of coverage is included in the reserve for unearned premiums. Reinsurance premiums for assumed business are estimated based on information received from brokers, ceding companies and reinsureds. Any subsequent differences arising on such estimates are recorded in the periods in which they are determined. For both ceded and assumed reinsurance, risk transfer requirements must be met for reinsurance accounting to apply. If risk transfer requirements are not met, the contract is accounted for as a deposit, resulting in the recognition of cash flows under the contract through a deposit asset or liability and not as revenue or expense. To meet risk transfer requirements, a reinsurance contract must include both insurance risk, consisting of both underwriting and timing risk, and a reasonable possibility of a significant loss for the assuming entity. Similar risk transfer criteria are used to determine whether directly written insurance contracts should be accounted for as insurance or as a deposit. Retroactive reinsurance agreements are reinsurance agreements under which our reinsurer agrees to reimburse us as a result of past insurable events. For these agreements, the excess of the amounts ultimately collectible under the agreement over the consideration paid is recognized as a deferred gain liability and amortized into income over the settlement period of the ceded reserves. The amount of the deferral is recalculated each period based on loss payments and updated estimates. If the consideration paid exceeds the ultimate losses collectible under the agreement, the net loss on the agreement is recognized in income immediately. Ceded loss reserves under retroactive agreements were $11.5 billion and $12.4 billion, and the deferred gain liability was $725 million and $585 million, as of December 31, 2024 and 2023, respectively. The effect on income from amortization of the deferred gain was $406 million, $82 million and $252 million for the years ended December 31, 2024, 2023 and 2022, respectively. FORTITUDE RE Fortitude Re is the reinsurer of the majority of AIG’s run-off operations. The reinsurance transactions are structured as modco and loss portfolio transfer arrangements with funds withheld (funds withheld). In modco and funds withheld arrangements, the investments supporting the reinsurance agreements, and which reflect the majority of the consideration that would be paid to the reinsurer for entering into the transaction, are withheld by, and therefore continue to reside on the balance sheet of, the ceding company (i.e., AIG) thereby creating an obligation for the ceding company to pay the reinsurer (i.e., Fortitude Re) at a later date. Additionally, as AIG maintains ownership of these investments, AIG will maintain its existing accounting for these assets (e.g., the changes in fair value of available for sale securities will be recognized within OCI). AIG has established a funds withheld payable to Fortitude Re while simultaneously establishing a reinsurance asset representing reserves for the insurance coverage that Fortitude Re has assumed. The funds withheld payable contains an embedded derivative and changes in fair value of the embedded derivative related to the funds withheld payable are recognized in earnings through Net realized gains (losses). This embedded derivative is considered a total return swap with contractual returns that are attributable to various assets and liabilities associated with these reinsurance agreements. REINSURANCE – CREDIT LOSSES The estimation of reinsurance recoverables involves a significant amount of judgment, particularly for latent exposures, such as asbestos, due to their long-tail nature. We assess the collectability of reinsurance recoverable balances in each reporting period, through either historical trends of disputes and credit events or financial analysis of the credit quality of the reinsurer. We record adjustments to reflect the results of these assessments through an allowance for credit losses and disputes on uncollectible reinsurance that reduces the carrying amount of reinsurance and deposit accounting assets on the consolidated balance sheets (collectively, reinsurance recoverables). This estimate requires significant judgment for which key considerations include: • paid and unpaid amounts recoverable; • whether the balance is in dispute or subject to legal collection; • the relative financial health of the reinsurer as classified by the Obligor Risk Ratings (ORRs) we assign to each reinsurer based upon our financial reviews; reinsurers that are financially troubled (i.e., in run-off, have voluntarily or involuntarily been placed in receivership, are insolvent, are in the process of liquidation or otherwise subject to formal or informal regulatory restriction) are assigned ORRs that will generate a significant allowance; and • whether collateral and collateral arrangements exist. An estimate of the reinsurance recoverable's lifetime expected credit losses is established utilizing a probability of default and loss given default method, which reflects the reinsurer’s ORR. The allowance for credit losses excludes disputed amounts. An allowance for disputes is established for a reinsurance recoverable using the losses incurred model for contingencies.
Deferred Policy Acquisition Costs	Deferred Policy Acquisition Costs (DAC) represent those costs that are incremental and directly related to the successful acquisition of new or renewal of existing insurance contracts. We defer incremental costs that result directly from, and are essential to, the acquisition or renewal of an insurance contract. Such DAC generally include agent or broker commissions and bonuses, premium taxes, and medical and inspection fees that would not have been incurred if the insurance contract had not been acquired or renewed. Each cost is analyzed to assess whether it is fully deferrable. We partially defer costs, including certain commissions, when we do not believe that the entire cost is directly related to the acquisition or renewal of insurance contracts. Commissions that are not deferred to DAC are recorded in General operating and other expenses in the Consolidated Statements of Income (Loss). We also defer a portion of employee total compensation and payroll-related fringe benefits directly related to time spent performing specific acquisition or renewal activities, including costs associated with the time spent on underwriting, policy issuance and processing, and sales force contract selling. The amounts deferred are derived based on successful efforts for each distribution channel and/or cost center from which the cost originates.
Variable Interest Entities	A variable interest entity (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 significant decisions relating to the entity’s operations through voting rights or do not substantively participate in the gains and losses of the entity. Consolidation of a VIE by its primary beneficiary is not based on majority voting interest, but is based on other criteria discussed below. We enter into various arrangements with VIEs in the normal course of business and consolidate the VIEs when we determine we are the primary beneficiary. This analysis includes a review of the VIE’s capital structure, related contractual relationships and terms, nature of the VIE’s operations and purpose, nature of the VIE’s interests issued and our involvement with the entity. When assessing the need to consolidate a VIE, we evaluate the design of the VIE as well as the related risks to which the entity was designed to expose the variable interest holders. The primary beneficiary is the entity that has both (i) the power to direct the activities of the VIE that most significantly affect the entity’s economic performance and (ii) the obligation to absorb losses or the right to receive benefits that could be potentially significant to the VIE. While also considering these factors, the consolidation conclusion depends on the breadth of our decision-making ability and our ability to influence activities that significantly affect the economic performance of the VIE.
Derivatives and Hedge Accounting	We use derivatives and other financial instruments as part of our financial risk management programs and as part of our investment operations. Interest rate derivatives (such as interest rate swaps) are used to manage interest rate risk associated with embedded derivatives contained in insurance contract liabilities, fixed maturity securities, outstanding medium- and long-term notes as well as other interest rate sensitive assets and liabilities. Foreign exchange derivatives (principally foreign exchange forwards and swaps) are used to economically mitigate risk associated with non-U.S. dollar denominated debt, net capital exposures, foreign currency transactions, and foreign denominated investments. Equity derivatives are used to economically mitigate financial risk associated with embedded derivatives. We use credit derivatives to manage our credit exposures. The derivatives are effective economic hedges of the exposures that they are meant to offset. In addition to hedging activities, we also enter into derivative contracts with respect to investment operations, which may include, among other things, CDSs, total return swaps and purchases of investments with embedded derivatives, such as equity-linked notes and convertible bonds. Interest rate, currency, equity swaps, credit contracts, swaptions, options and forward transactions are accounted for as derivatives, recorded on a trade-date basis and carried at fair value. Unrealized gains and losses are reflected in income, when appropriate. Aggregate asset or liability positions are netted on the Consolidated Balance Sheets only to the extent permitted by qualifying master netting arrangements in place with each respective counterparty. Cash collateral posted with counterparties in conjunction with transactions supported by qualifying master netting arrangements is reported as a reduction of the corresponding net derivative liability, while cash collateral received in conjunction with transactions supported by qualifying master netting arrangements is reported as a reduction of the corresponding net derivative asset. Derivatives, with the exception of embedded derivatives, are reported at fair value in the Consolidated Balance Sheets in Other assets and Other liabilities. Embedded derivatives are generally presented with the host contract in the Consolidated Balance Sheets. A bifurcated embedded derivative is measured at fair value and accounted for in the same manner as a free standing derivative contract. The corresponding host contract is accounted for according to the accounting guidance applicable for that instrument. We designated certain derivatives entered into with third parties as fair value hedges of available for sale investment securities held by our insurance subsidiaries. The fair value hedges include foreign currency forwards and cross currency swaps designated as hedges of the change in fair value of foreign currency denominated available for sale securities attributable to changes in foreign exchange rates. We use foreign currency denominated debt and cross-currency swaps as hedging instruments in net investment hedge relationships to mitigate the foreign exchange risk associated with our non-U.S. dollar functional currency foreign subsidiaries. For net investment hedge relationships where issued debt is used as a hedging instrument, we assess the hedge effectiveness and measure the amount of ineffectiveness based on changes in spot rates. For net investment hedge relationships that use derivatives as hedging instruments, we assess hedge effectiveness and measure hedge ineffectiveness using changes in forward rates. For the years ended December 31, 2024, 2023 and 2022, we recognized gains (losses) of $86 million, $(42) million and $305 million, respectively, included in Change in foreign currency translation adjustments in OCI related to the net investment hedge relationships. A qualitative methodology is utilized to assess hedge effectiveness.
Goodwill and Other Intangible Assets	Goodwill represents the future economic benefits arising from assets acquired in a business combination that are not individually identified and separately recognized. Goodwill is tested for impairment at the reporting unit level, which is defined as a segment or one level below, and the test is performed annually, or more frequently if circumstances indicate an impairment may have occurred. At December 31, 2024, goodwill is reported within North America Commercial, International Commercial and Global Personal segments, and within Other Operations. When a business is transferred from one reporting unit to another, goodwill from the original reporting unit is allocated among reporting units based on the fair value of business transferred, relative to business retained by a reporting unit. The impairment assessment involves an option to first assess qualitative factors to determine whether events or circumstances exist that lead to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the qualitative assessment is not performed, or after assessing the totality of the events or circumstances, we determine it is more likely than not that the fair value of a reporting unit is less than its carrying amount, a quantitative assessment for potential impairment is performed. If the qualitative test is not performed or if the test indicates a potential impairment is present, we estimate the fair value of each reporting unit and compare the estimated fair value with the carrying amount of the reporting unit, including allocated goodwill. The estimate of a reporting unit’s fair value involves management judgment and is based on one or a combination of approaches including discounted expected future cash flows, market-based earnings multiples of the unit’s peer companies, external appraisals or, in the case of reporting units being considered for sale, third-party indications of fair value, if available. We consider one or more of these estimates when determining the fair value of a reporting unit to be used in the impairment test. If the estimated fair value of a reporting unit exceeds its carrying amount, goodwill is not impaired. If the carrying value of a reporting unit exceeds its estimated fair value, goodwill associated with that reporting unit potentially is impaired. The amount of impairment, if any, is measured as the excess of a reporting unit’s carrying amount over its fair value not to exceed the total amount of goodwill allocated to that reporting unit and recognized in income. Indefinite lived intangible assets are not subject to amortization. Indefinite lived intangible assets primarily include Lloyd’s syndicate capacity and brand names. Finite lived intangible assets are amortized over their useful lives. Finite lived intangible assets primarily include distribution networks and are recorded net of accumulated amortization. The Company tests indefinite lived intangible assets for impairment on an annual basis or whenever events or circumstances suggest that the carrying value of an intangible asset may exceed the sum of the undiscounted cash flows expected to result from its use and eventual disposition. If this condition exists and the carrying value of an intangible asset exceeds its fair value, the excess is recognized as an impairment and is recorded as a charge against net income (loss).
Liability for Unpaid Losses and Loss Adjustment Expenses (Loss Reserves)	Loss reserves represent the accumulation of estimates of unpaid claims, including estimates for claims incurred but not reported and loss adjustment expenses, less applicable discount. We regularly review and update the methods used to determine loss reserve estimates. Any adjustments resulting from this review are reflected currently in pre-tax income, except to the extent such adjustment impacts a deferred gain under a retroactive reinsurance agreement, in which case the ceded portion would be amortized into pre-tax income in subsequent periods. Because these estimates are subject to the outcome of future events, changes in estimates are common given that loss trends vary and time is often required for changes in trends to be recognized and confirmed. Reserve changes that increase previous estimates of ultimate cost are referred to as unfavorable or adverse development or reserve strengthening. Reserve changes that decrease previous estimates of ultimate cost are referred to as favorable development or reserve releases. We use a combination of methods to project ultimate losses for both long-tail and short-tail exposures, which include: • Paid Development method: The Paid Development method estimates ultimate losses by reviewing paid loss patterns and selecting paid ultimate loss development factors. These factors are then applied to paid losses by applying them to accident years, with further expected changes in paid loss. Since the method does not rely on case reserves, it is not directly influenced by changes in the adequacy of case reserves. • Incurred Development method: The Incurred Development method is similar to the Paid Development method, but it uses case incurred losses instead of paid losses. Since this method uses more data (case reserves in addition to paid losses) than the Paid Development method, the incurred development patterns may be less variable than paid development patterns. • Expected Loss Ratio method: The Expected Loss Ratio method multiplies premiums by an expected loss ratio to produce ultimate loss estimates for each accident year. This method may be useful if loss development patterns are inconsistent, losses emerge very slowly, or there is relatively little loss history from which to estimate future losses. Expected loss ratio methods for business written in excess of a deductible may be given significant weight in the most recent five accident years. The expected loss ratios used for recent accident years are based on the projected ultimate loss ratios for older years adjusted for rate changes, loss trend including inflation, and where appropriate, changing market conditions. • Bornhuetter-Ferguson method: The Bornhuetter-Ferguson method using premiums and paid losses is a combination of the Paid Development method and the Expected Loss Ratio method where the weight given to each method is the reciprocal of the loss development factor. This method normally determines expected loss ratios similar to the method used for the Expected Loss Ratio method. The Bornhuetter-Ferguson method using premiums and incurred losses is similar to the Bornhuetter-Ferguson method using premiums and paid losses except that it uses case-incurred losses. • Cape Cod method: The Cape Cod method is mechanically similar to the Bornhuetter-Ferguson method with the difference being that the Expected Loss Ratio estimates are determined based on a weighting of the loss estimates that come from the Paid/Incurred Development Methods. This method may be more responsive to recent loss trends than the Bornhuetter-Ferguson method. • Average Loss method: The Average Loss method multiplies a projected number of ultimate claims by an estimated ultimate severity average loss for each accident year to produce ultimate loss estimates. Since projections of the ultimate number of claims are often less variable than projections of ultimate loss, this method can provide more reliable results for reserve categories where loss development patterns are inconsistent or too variable to be relied on exclusively. In updating our loss reserve estimates, we consider and evaluate inputs from many sources, including actual claims data, the performance of prior reserve estimates, observed industry trends, our internal peer review processes, including challenges and recommendations from our Enterprise Risk Management group, as well as the views of third-party actuarial firms. We use these inputs to improve our evaluation techniques, and to analyze and assess the change in estimated ultimate loss for each accident year by product line. Our analyses produce a range of indications from various methods, from which we select our best estimate. In determining the actual carried loss reserves, we consider both the internal actuarial best estimate and numerous other internal and external factors, including: • an assessment of economic conditions, including real GDP growth, inflation, employment rates or unemployment duration, stock market volatility and changes in corporate bond spreads; • changes in the legal, regulatory, judicial and social environment, including changes in road safety, public health and cleanup standards; • changes in medical cost trends (inflation, intensity and utilization of medical services) and wage inflation trends; • underlying policy pricing, terms and conditions including attachment points and policy limits; • change in claims handling philosophy, operating model, processes, and related ongoing enhancements; • third-party claims reviews that are periodically performed for key classes of claims such as toxic tort, environmental and other complex casualty claims; • third-party actuarial reviews that are periodically performed for key classes of business; • input from underwriters on pricing, terms, and conditions and market trends; and • changes in our reinsurance program, pricing and commutations. Where appropriate and identifiable, adjustments have been made to standard projection techniques. Changes in Claims organization management, differing referral and review criteria and other factors may also be expected to alter loss emergence. The following factors are relevant to the loss development information included in the tables below: • Table organization: The tables are organized by accident year and include policies written on an occurrence and claims- made basis. We note that for certain categories of claims (e.g., construction defect claims and environmental claims) and for reinsurance recoverable, losses may sometimes be reclassified to an earlier or later accident year as more information about the date of occurrence becomes available to us. These reclassifications are shown as development in the respective years in the tables below. Financial Lines business is primarily written on a claims-made basis, while the majority of the workers’ compensation, excess casualty, other casualty, and run-off property and casualty lines of business are written on an occurrence basis. Primarily, all short-tail lines in Property and Special Risks and Personal Insurance are written on an occurrence basis. • Groupings: We believe our groupings have homogenous risk characteristics with similar development patterns and would generally be subject to similar trends and reflect our reportable segments. The incurred losses and loss adjustment expenses and paid losses in the following tables for the current reporting year are allocated to the line of business and accident years based on how the business is coded by profit center and line of business. • Reinsurance: Our reinsurance program varies by exposure type. Historically we have leveraged facultative and treaty reinsurance, both on a pro-rata and excess of loss basis. Our reinsurance program may change from year to year, which may affect the comparability of the data presented in our tables. • Adverse development reinsurance agreement: We have provided the impact of the ADC in an additional table below our Incurred Losses and Allocated Loss Adjustment Expenses tables. The impact of the ADC is shown beginning in 2016 given the retroactive date of the contract and coincides with the effective date of the contract. For the lines of business covered by the agreement (U.S. Workers' Compensation, U.S. Excess Casualty, U.S. Other Casualty, U.S. Financial Lines, U.S. Property and Special Risks and U.S. Personal Insurance or collectively, the Covered Lines), an attribution of the loss recoveries to the line of business by calendar year and accident year is performed based on the underlying distribution of the losses subject to the agreement. Specifically, the future claim payments for all subject incurred losses were projected into future years based on the same actuarial assumptions underlying the related reserves. The additional table presented after discussion of prior year development by line of business reconciles the changes in net ultimates to our overall prior year development and provides the reattribution of loss recoveries for the Covered Lines. The reinsurance terms of the ADC were then used to identify the future claims payments for which 80% will be reimbursed by NICO. At each reporting period, the attribution of the ADC recoveries is performed. The factors that could cause the attribution to lines of business and accident year to change include changes in underlying actuarial assumptions as to timing and amount of future claim payments. • Incurred but not reported liabilities (IBNR): We include development from past reported losses in IBNR. • Data excluded from tables: Information with respect to accident years older than ten years is excluded from the development tables. Unallocated loss adjustment expenses are also excluded. • Foreign exchange: The loss development for operations outside of the U.S. is presented for all accident years using the current exchange rate at December 31, 2024. Although this approach requires restating all prior accident year information, the changes in exchange rates do not impact incurred and paid loss development trends. • Acquisitions: We include acquisitions from all accident years presented in the tables. For purposes of this disclosure, we have applied the retrospective method for the acquired reserves, including incurred and paid claim development histories throughout the relevant tables. It should be noted that historical reserves for the acquired businesses were established by the acquired companies using methods, assumptions and procedures then in effect which may differ from our current reserving bases. Accordingly, it may not be appropriate to extrapolate future redundancies or deficiencies based on the aggregated historical results shown in the triangles. • Dispositions: We exclude dispositions from all accident years presented in the tables. • Claim counts: We consider a reported claim to be one claim for each claimant or feature for each loss occurrence. Claims relating to losses that are 100 percent reinsured are excluded from the reported claims in the tables below. Reported claims for losses from assumed reinsurance contracts are not available and hence not included in the reported claims. There are limitations that should be considered on the reported claim count data in the tables below, including: – Claim counts are presented only on a reported (not an ultimate) basis; – The tables below include lines of business and geographies at a certain aggregated level which may indicate different frequency and severity trends and characteristics, and may not be as meaningful as the claim count information related to the individual products within those lines of business and geographies; – Certain lines of business are more likely to be subject to occurrences involving multiple claimants and features, which can distort measures based on the reported claim counts in the table below; and – Reported claim counts are not adjusted for ceded reinsurance, which may distort the measure of frequency or severity.
Future Policy Benefits	FUTURE POLICY BENEFITS
Debt	Our long-term debt is denominated in various currencies, with both fixed and variable interest rates. Long-term debt is carried at the principal amount borrowed, including unamortized discounts, hedge accounting valuation adjustments and fair value adjustments, when applicable.
Earnings Per Share	The basic EPS computation is based on the weighted average number of common shares outstanding, adjusted to reflect all stock dividends and stock splits. The diluted EPS computation is based on those shares used in the basic EPS computation plus common shares that would have been outstanding assuming issuance of common shares for all dilutive potential common shares outstanding and adjusted to reflect all stock dividends and stock splits, using the treasury stock method or the if-converted method, as applicable.
Tax Accounting Policies	TAX ACCOUNTING POLICIES We consider our foreign earnings with respect to certain operations in Canada, South Africa, Japan, Latin America, Bermuda as well as the European, Asia Pacific and Middle East regions to be indefinitely reinvested. These earnings relate to ongoing operations and have been reinvested in active business operations. A deferred tax liability has not been recorded for those foreign subsidiaries whose earnings are considered to be indefinitely reinvested. If recorded, such deferred tax liability would not be material to our consolidated financial condition. Deferred taxes, if necessary, have been provided on earnings of non-U.S. affiliates whose earnings are not indefinitely reinvested. Global Intangible Low-Taxed Income (GILTI) imposes U.S. taxes on the excess of a deemed return on tangible assets of certain foreign subsidiaries. Consistent with accounting guidance, we have made an accounting policy election to treat GILTI taxes as a period tax charge in the period the tax is incurred. ASSESSMENT OF DEFERRED TAX ASSET VALUATION ALLOWANCE The evaluation of the recoverability of our deferred tax asset and the need for a valuation allowance requires us to weigh all positive and negative evidence to reach a conclusion that it is more likely than not that all or some portion of the deferred tax asset will not be realized. The weight given to the evidence is commensurate with the extent to which it can be objectively verified. The more negative evidence that exists, the more positive evidence is necessary and the more difficult it is to support a conclusion that a valuation allowance is not needed. During the fourth quarter, taxable income projections were updated to reflect the latest projections of income for our insurance and non-insurance companies, 2024 transactions, and projections of taxable income generated from prudent and feasible tax planning strategies. Given there is a shorter carryforward period to utilize remaining net operating losses, we continue to consider multiple data points and stresses. Additionally, significant market volatility continues to impact actual and projected results of our business operations as well as our views on potential effectiveness of certain prudent and feasible tax planning strategies. In order to demonstrate the predictability and sufficiency of future taxable income necessary to support the realizability of the net operating losses and foreign tax credit carryforwards, we have considered forecasts of future income for each of our businesses, including assumptions about future macroeconomic and AIG-specific conditions and events, and any impact these conditions and events may have on our prudent and feasible tax planning strategies. We also subjected the forecasts to a variety of stresses of key assumptions and evaluated the effect on tax attribute utilization.

Fair Value Measurement Inputs and Valuation Techniques	The table below presents information about the significant unobservable inputs used for recurring fair value measurements for certain Level 3 instruments, and includes only those instruments for which information about the inputs is reasonably available to us, such as data from independent third-party valuation service providers. Because input information from third-parties with respect to certain Level 3 instruments (primarily CLO/ABS) may not be reasonably available to us, balances shown below may not equal total amounts reported for such Level 3 assets and liabilities: (in millions) Fair Value at Valuation Unobservable Input (b) Range (Weighted Average) (c) Assets: Obligations of states, municipalities and political subdivisions $ 3 Discounted cash flow Yield 5.09% - 5.57% (5.33%) Corporate debt 177 Discounted cash flow Yield 6.83% - 11.61% (9.22%) RMBS (a) 1,321 Discounted cash flow Constant prepayment rate 4.10% - 9.26% (6.68%) Loss severity 40.81% - 76.72% (58.76%) (in millions) Fair Value at Valuation Unobservable Input (b) Range (Weighted Average) (c) Constant default rate 0.57% - 2.48% (1.52%) Yield 5.89% - 6.98% (6.44%) CLO/ABS (a) 760 Discounted cash flow Yield 4.24% - 8.42% (6.33%) CMBS 25 Discounted cash flow Yield 7.04% - 10.12% (8.70%) (in millions) Fair Value at Valuation Unobservable Input (b) Range (Weighted Average) (c) Assets: Obligations of states, municipalities and political subdivisions $ 3 Discounted cash flow Yield 5.00% - 5.50% (5.23%) Corporate debt 332 Discounted cash flow Yield 5.16% - 9.62% (7.39%) RMBS (a) 1,341 Discounted cash flow Constant prepayment rate 4.43% - 10.30% (7.36%) Loss severity 43.21% - 76.65% (59.93%) Constant default rate 0.82% - 2.64% (1.73%) Yield 6.18% - 7.42% (6.80%) CLO/ABS (a) 1,100 Discounted cash flow Yield 5.31% - 8.56% (6.94%) CMBS 22 Discounted cash flow Yield 9.84% - 17.24% (13.54%) (a) Information received from third-party valuation service providers. The ranges of the unobservable inputs for constant prepayment rate, loss severity and constant default rate relate to each of the individual underlying mortgage loans that comprise the entire portfolio of securities in the RMBS and CLO securitization vehicles and not necessarily to the securitization vehicle bonds (tranches) purchased by us. The ranges of these inputs do not directly correlate to changes in the fair values of the tranches purchased by us, because there are other factors relevant to the fair values of specific tranches owned by us including, but not limited to, purchase price, position in the waterfall, senior versus subordinated position and attachment points. (b) Represents discount rates, estimates and assumptions that we believe would be used by market participants when valuing these assets and liabilities. (c)
Schedule of Net Asset Value Per Share	The following table includes information related to our investments in certain other invested assets, including private equity funds, hedge funds and other alternative investments that calculate net asset value per share (or its equivalent). For these investments, which are measured at fair value on a recurring basis, we use the net asset value per share to measure fair value. December 31, 2024 December 31, 2023 (in millions) Investment Category Includes Fair Value Using NAV Per Share (or its equivalent) Unfunded Commitments Fair Value Using NAV Per Share (or its equivalent) Unfunded Commitments Investment Category Private equity funds: Leveraged buyout Debt and/or equity investments made as part of a transaction in which assets of mature companies are acquired from the current shareholders, typically with the use of financial leverage $ 1,126 $ 375 $ 1,171 $ 558 Real assets Investments in real estate properties, agricultural and infrastructure assets, including power plants and other energy producing assets 782 261 870 344 Venture capital Early-stage, high-potential, growth companies expected to generate a return through an eventual realization event, such as an initial public offering or sale of the company 83 40 67 50 Growth equity Funds that make investments in established companies for the purpose of growing their businesses 175 1 196 9 Mezzanine Funds that make investments in the junior debt and equity securities of leveraged companies 120 58 140 56 Other Includes distressed funds that invest in securities of companies that are in default or under bankruptcy protection, as well as funds that have multi- strategy, and other strategies 819 57 944 64 Total private equity funds 3,105 792 3,388 1,081 Hedge funds: Event-driven Securities of companies undergoing material structural changes, including mergers, acquisitions and other reorganizations 11 — 13 — Long-short Securities that the manager believes are undervalued, with corresponding short positions to hedge market risk 168 — 389 — Other Includes investments held in funds that are less liquid, as well as other strategies which allow for broader allocation between public and private investments 8 — 9 — Total hedge funds 187 — 411 — Total $ 3,292 $ 792 $ 3,799 $ 1,081

It is our policy to reverse compensation expense for forfeited awards when they occur. (b) We also recognized $16 million of tax benefit due to share settlements occurring in 2024.
Schedule of Assumptions Used to Estimate the Fair Value of PSUs Based on AIG's TSR	The following table presents the assumptions used to estimate the fair value of PSUs that vest based on AIG’s TSR: 2024 2023 2022 Expected dividend yield (a) — % — % — % Expected volatility (b) 28.72 % 37.98 % 47.60 % Risk-free interest rate (c) 4.36 % 4.42 % 1.71 % (a) The award agreement provides that TSR for AIG and each member of the Peer Group will be calculated assuming dividends distributed are reinvested on the ex‑dividend date. (b) We used the historical volatility over the most recent 2.86-year period for AIG and the members of the Peer Group, commensurate with the remaining Performance Period as of the valuation date. (c) We converted the semi-annual zero-coupon U.S. Treasury rates as of the valuation date to continuously compounded rates. We then chose the continuously compounded risk-free rate that is commensurate with the length of the remaining performance period as of the valuation date and interpolated between the yields of the two-year and the three-year continuously compounded rates to determine the yield.

(c) Also reflects units that vest as a result of an accelerated vesting event that occurred prior to the specified vesting date but for which share delivery has not yet occurred. (d) At December 31, 2024, the total unrecognized compensation cost for outstanding RSUs and PSUs was $96 million and the weighted-average and expected period of years over which that cost is expected to be recognized are 1.00 year and 2.25 years.
Schedule of Weighted-Average Assumptions	The following weighted-average assumptions were used for stock options granted: 2024 2023 2022 Expected annual dividend yield (a) 2.11 % 2.14 % 2.08 % Expected volatility (b) 25.27 % 25.17 % 32.13 % Risk-free interest rate (c) 4.21 % 4.06 % 1.92 % Expected term (d) 6.00 years 6.00 years 6.00 years (a) The dividend yield is the last dividend from Bloomberg times 4 divided by stock price based on Bloomberg Professional service as of the valuation date. (b) The expected volatility is based on the implied volatility of 24 months stock option estimated by the Bloomberg Professional service as of the valuation date. (c) We converted the semi-annual zero-coupon U.S. Treasury rates as of the valuation date to continuously compounded rates. We then chose the continuously compounded risk-free rate that is commensurate with the length of the remaining performance period as of the valuation date and interpolated between the yields of the two-year and the three-year continuously compounded rates to determine the yield. (d) The contractual term is 10 years from the date of grant.
