Summary of Significant Accounting Policies (Policies)	12 Months Ended
Summary of Significant Accounting Policies (Policies)	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. All material intercompany accounts and transactions have been eliminated.
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. These accounting estimates require the use of assumptions about matters, some of which are highly uncertain at the time of estimation. To the extent actual experience differs from the assumptions used, our consolidated financial condition, results of operations and cash flows could be materially affected.
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. 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	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 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. 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. •Prepayment premiums. 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. 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	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 On November 4, 2024, the FASB issued new guidance requiring additional disclosure of the nature of expenses included in the income statement. The new standard requires disclosures about specific types of expenses included in the expense captions presented on the face of the income statement. The guidance is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027. The requirements will be applied prospectively with the option for retrospective application. We are assessing the impact of the standard.
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 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. 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). 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. 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.
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 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. 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 Future policy benefits primarily include reserves for traditional life and annuity payout contracts, which represent an estimate of the present value of future benefits less the present value of future net premiums. For traditional and limited pay long-duration products, benefit reserves are accrued and benefit expense is recognized using a net premium ratio methodology for each annual cohort of business.
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.
