Accounting Policies [Abstract] |
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; and •income taxes, in particular the recoverability of our deferred tax asset and establishment of provisions for uncertain tax positions. 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.
Future Application of Accounting Standards | FUTURE APPLICATION OF ACCOUNTING STANDARDS Income Tax In December 2023, the Financial Accounting Standards Board (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 disclosure impact of this standard on our financial statements. Disaggregation of Income Statement Expenses On November 4, 2024, the FASB issued new guidance that is intended to improve disclosures regarding the nature of expenses included in the income statement. The standard will require companies to disaggregate certain expense captions into specified categories in disclosures within notes to the financial statements and provide qualitative descriptions for those that are not separately disclosed. 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 can be applied prospectively or retrospectively for prior periods presented when adopted. 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 year's 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, 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. OTHER OPERATIONS Other Operations predominantly consists of Net Investment Income from our AIG Parent liquidity portfolio, Corebridge Financial, Inc. (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 deferred policy acquisition costs (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 | Assets and liabilities recorded at fair value in the Condensed 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. 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.
Investments | We purchase certain RMBS 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. 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 agreements to resell (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.
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 | LOAN MODIFICATIONS The allowance for credit losses incorporates an estimate of lifetime expected credit losses and is recorded on each asset upon asset origination or acquisition. The starting point for the estimate of the allowance for credit losses is historical loss information, which includes losses from modifications of receivables to borrowers experiencing financial difficulty. We use a probability of default/loss given default model to determine the allowance for credit losses for our commercial mortgage loans. An assessment of whether a borrower is experiencing financial difficulty is made on the date of a modification. Because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses utilizing the measurement methodologies used to estimate the allowance, a change to the allowance for credit losses is generally not recorded upon modification. When modifications are executed, they often will be in the form of principal forgiveness, term extensions, interest rate reductions, or some combination of any of these concessions. When principal is forgiven, the amortized cost basis of the asset is written off against the allowance for credit losses. The amount of the principal forgiveness is deemed to be uncollectible; therefore, that portion of the loan is written off, resulting in a reduction of the amortized cost basis and a corresponding adjustment to the allowance for credit losses. We assess whether a borrower is experiencing financial difficulty based on a variety of factors, including the borrower’s current default on any of its outstanding debt, the probability of a default on any of its debt in the foreseeable future without the modification, the insufficiency of the borrower’s forecasted cash flows to service any of its outstanding debt (including both principal and interest), and the borrower’s inability to access alternative third-party financing at an interest rate that would be reflective of current market conditions for a non-troubled debtor. REINSURANCE – 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 | 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 | 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 were related directly to the successful acquisition of new or renewal insurance contracts. 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 Condensed Consolidated Statements of Income (Loss). We also defer a portion of employee total compensation and payroll-related fringe benefits directly related to time spent performing specific acquisition or renewal activities, including costs associated with the time spent on underwriting, policy issuance and processing, and sales force contract selling. The amounts deferred are derived based on successful efforts for each distribution channel and/or cost center from which the cost originates.
Variable Interest Entities | We enter into various arrangements with Variable Interest Entities (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, credit default swaps (CDSs), total return swaps and purchases of investments with embedded derivatives, such as equity-linked notes and convertible bonds. 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 Condensed 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 three and six months ended June 30, 2025, we recognized gains (losses) of $(101) million and $(172) million, respectively, and for the three and six months ended June 30, 2024, we recognized gains (losses) of $9 million and $34 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.
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.
Earnings Per Share | Basic EPS is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding. The diluted EPS computation assumes the issuance of all potentially dilutive common shares outstanding using the treasury stock method or the if-converted method, as applicable, and excludes the effect of anti-dilutive shares.
Tax Accounting Policies | On July 4, 2025, new U.S. tax legislation was signed into law (known as the "One Big Beautiful Bill Act" or "OBBB Act") which, among other provisions, makes permanent many of the tax provisions enacted in 2017 as part of the Tax Cuts and Jobs Act that were set to expire at the end of 2025. We are currently evaluating the impact of the new legislation, but do not expect it to have a material impact on the results of operations. 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. 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 second quarter, taxable income projections were updated to reflect the latest projections of income for our insurance and non-insurance companies, 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.
