4. Fair Value Measurements

FAIR VALUE MEASUREMENTS ON A RECURRING BASIS

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.

ASSETS AND LIABILITIES MEASURED AT FAIR VALUE ON A RECURRING BASIS

The following table presents information about assets and liabilities measured at fair value on a recurring basis and indicates the level of the fair value measurement based on the observability of the inputs used:

(a)Represents netting of derivative exposures covered by qualifying master netting agreements.

(b)As of March 31, 2026, includes AIG's ownership interests in Corebridge and Onex of $607 million and $548 million, respectively.

(c)Excludes investments that are measured at fair value using the net asset value (NAV) per share (or its equivalent), which totaled $3.1 billion and $3.3 billion as of March 31, 2026 and December 31, 2025, respectively. As of December 31, 2025, includes AIG's ownership interest in Corebridge of $1.5 billion on which AIG elected the fair value option.

(d)Presented as part of Other assets and Other liabilities on the Condensed Consolidated Balance Sheets.

CHANGES IN LEVEL 3 RECURRING FAIR VALUE MEASUREMENTS

The following tables present changes during the three months ended March 31, 2026 and 2025 in Level 3 assets and liabilities measured at fair value on a recurring basis, and the realized and unrealized gains (losses) related to the Level 3 assets and liabilities in the Condensed Consolidated Balance Sheets at March 31, 2026 and 2025:

Net realized and unrealized gains and losses included in income related to Level 3 assets and liabilities shown above are reported in the Condensed Consolidated Statements of Income (Loss) as follows:

The following table presents the gross components of purchases, sales, issuances and settlements, net, shown above, for the three months ended March 31, 2026 and 2025 related to Level 3 assets and liabilities in the Condensed Consolidated Balance Sheets:

(a)There wereno issuances during the three months ended March 31, 2026 and 2025.

Both observable and unobservable inputs may be used to determine the fair values of positions classified in Level 3 in the tables above. As a result, the unrealized gains (losses) on instruments held at March 31, 2026 and 2025 may include changes in fair value that were attributable to both observable (e.g., changes in market interest rates) and unobservable inputs (e.g., changes in unobservable long-dated volatilities).

Transfers of Level 3 Assets and Liabilities

The Net realized and unrealized gains (losses) included in income (loss) or Other comprehensive income (loss) (OCI) as shown in the table above excludes $0 million and $2 million of net gains (losses) related to assets and liabilities transferred into Level 3 during the three months ended March 31, 2026 and 2025, respectively, and includes $1 million and $5 million of net gains (losses) related to assets and liabilities transferred out of Level 3 during the three months ended March 31, 2026 and 2025, respectively.

Transfers of Level 3 Assets

During the three months ended March 31, 2026 and 2025, transfers into Level 3 assets included investments in private placement corporate debt, commercial mortgage-backed securities (CMBS), residential mortgage-backed securities (RMBS), collateralized loan obligations (CLO)/asset backed securities (ABS) and equity securities. Transfers of private placement corporate debt and certain ABS into Level 3 assets were primarily the result of limited market pricing information that required us to determine fair value for these securities based on inputs that are adjusted to better reflect our own assumptions regarding the characteristics of a specific security or associated market liquidity. The transfers of investments in CMBS, RMBS, CLO and certain ABS into Level 3 assets were due to diminished market transparency and liquidity for individual security types.

During the three months ended March 31, 2026 and 2025, transfers out of Level 3 assets primarily included investments in private placement corporate debt, RMBS, CLO/ABS and other invested assets. Transfers of private placement corporate debt out of Level 3 assets were based on consideration of market liquidity as well as related transparency of pricing and associated observable inputs for these investments. Transfers of certain investments in private placement corporate debt out of Level 3 assets were primarily the result

of using observable pricing information that reflects the fair value of those securities without the need for adjustment based on our own assumptions regarding the characteristics of a specific security or the current liquidity in the market.

Transfers of Level 3 Liabilities

There were no significant transfers of derivative or other liabilities into or out of Level 3 for the three months ended March 31, 2026 and 2025.

QUANTITATIVE INFORMATION ABOUT LEVEL 3 FAIR VALUE MEASUREMENTS

The table below presents information about the significant unobservable inputs used for recurring fair value measurements for certain Level 3 instruments, and includes only those instruments for which information about the inputs is reasonably available to us, such as data from independent third-party valuation service providers. Because input information from third parties with respect to certain Level 3 instruments (primarily CLO/ABS) may not be reasonably available to us, balances shown below may not equal total amounts reported for such Level 3 assets and liabilities:

(a)Information received from third-party valuation service providers. The ranges of the unobservable inputs for constant prepayment rate, loss severity and constant default rate relate to each of the individual underlying mortgage loans that comprise the entire portfolio of securities in the RMBS and CLO securitization vehicles and not necessarily to the securitization vehicle bonds (tranches) purchased by us. The ranges of these inputs do not directly correlate to changes in the fair values of the tranches purchased by us, because there are other factors relevant to the fair values of specific tranches owned by us including, but not limited to, purchase price, position in the waterfall, senior versus subordinated position and attachment points.

(b)Represents discount rates, estimates and assumptions that we believe would be used by market participants when valuing these assets and liabilities.

(c)The weighted averaging for fixed maturity securities is based on the estimated fair value of the securities.

The ranges of reported inputs for Obligations of states, municipalities and political subdivisions, Corporate debt, RMBS, CLO/ABS, and CMBS valued using a discounted cash flow technique consist of one standard deviation in either direction from the value‑weighted average. The preceding table does not give effect to our risk management practices that might offset risks inherent in these Level 3 assets and liabilities.

Interrelationships Between Unobservable Inputs

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 IN CERTAIN ENTITIES CARRIED AT FAIR VALUE USING NET ASSET VALUE PER SHARE

The following table includes information related to our investments in certain other invested assets, including private equity funds, hedge funds and other alternative investments that calculate net asset value per share (or its equivalent). For these investments, which are measured at fair value on a recurring basis, we use the net asset value per share to measure fair value.

Private equity fund investments included above are not redeemable, because distributions from the funds will be received when underlying investments of the funds are liquidated. Private equity funds are generally expected to have 10-year lives at their inception, but these lives may be extended at the fund manager’s discretion, typically inone-year ortwo-year increments.

FAIR VALUE OPTION

The following table presents the gains or losses recorded related to the eligible instruments for which we elected the fair value option:

(a)Includes certain securities supporting the funds withheld arrangements with Fortitude Re. For additional information regarding the gains and losses for Other bond securities, see Note 5. For additional information regarding the funds withheld arrangements with Fortitude Re, see Note 7.

(b)Includes certain hedge funds, private equity funds and real estate investments.

(c)Represents the impact of changes in Corebridge stock price on the value of AIG's ownership interest in Corebridge and gain/loss on sale of shares through March 31, 2026. At March 31, 2026, AIG's remaining interest in Corebridge changed from being recognized as an equity method investment in Other invested assets to an equity security, at fair value. For additional information, see Note 1.

FAIR VALUE INFORMATION ABOUT FINANCIAL INSTRUMENTS NOT MEASURED AT FAIR VALUE

The following table presents the carrying amounts and estimated fair values of our financial instruments not measured at fair value and indicates the level in the fair value hierarchy of the estimated fair value measurement based on the observability of the inputs used:
