BASIS OF PRESENTATION
BASIS OF PRESENTATION	1. Basis of Presentation American International Group, Inc. (AIG) is a leading global insurance organization serving customers in approximately 80 countries and jurisdictions. AIG companies serve commercial and individual customers through one of the most extensive worldwide property-casualty networks of any insurer. In addition, AIG companies are leading providers of life insurance and retirement services in the United States. AIG Common Stock, par value $ 2.50 per share (AIG Common Stock), is listed on the New York Stock Exchange (NYSE: AIG). Unless the context indicates otherwise, the terms “AIG,” “we,” “us” or “our” mean American International Group, Inc. and its consolidated subsidiaries and the term “AIG Parent” means American International Group, Inc. and not any of its consolidated subsidiaries. The consolidated financial statements include the accounts of AIG Parent, our controlled subsidiaries (generally through a greater than 50 percent ownership of voting rights and voting interests), and variable interest entities (VIEs) of which we are the primary beneficiary. Equity investments in entities that we do not consolidate, including corporate entities in which we have significant influence and partnership and partnership-like entities in which we have more than minor influence over the operating and financial policies, are accounted for under the equity method unless we have elected the fair value option. Certain of our foreign subsidiaries included in the Consolidated Financial Statements report on the basis of a fiscal period ending November 30. The effect on our consolidated financial condition and results of operations of all material events occurring at these subsidiaries through the date of each of the periods presented in these Consolidated Financial Statements has been considered for adjustment and/or disclosure. The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP). All material intercompany accounts and transactions have been eliminated. AcquisitionS of Businesses Validus On July 18, 2018, we completed the purchase of Validus Holdings, Ltd. (Validus), a leading provider of reinsurance, primary insurance, and asset management services, for $ 5.5 billion in cash. The results of Validus following the date of the acquisition are included in our General Insurance segment starting in the third quarter of 2018. Our North America results include the results of Validus Reinsurance, Ltd. and Western World Insurance Group, Inc., while our International results include the results of Talbot Holdings Ltd. For additional information relating to the acquisition of Validus, see Note 4. Glatfelter On November 6, 2018 AIG completed the purchase of Glatfelter Insurance Group (Glatfelter), a full-service broker and insurance company providing services for specialty programs and retail operations. Ellipse On December 31, 2018, AIG Life Ltd., a UK AIG Life and Retirement company, completed the acquisition of Ellipse, a specialist provider of group life risk protection in the UK. Sales/disposals of Businesses Fortitude Holdings On June 2, 2020, we completed the sale of a majority of the interests in Fortitude Group Holdings, LLC (Fortitude Holdings) to Carlyle FRL, L.P. (Carlyle FRL), an investment fund advised by an affiliate of The Carlyle Group Inc. (Carlyle), and T&D United Capital Co., Ltd. (T&D), a subsidiary of T&D Holdings, Inc., under the terms of a membership interest purchase agreement entered into on November 25, 2019 by and among AIG, Fortitude Holdings, Carlyle FRL, Carlyle, T&D and T&D Holdings, Inc. (the Majority Interest Fortitude Sale). AIG established Fortitude Reinsurance Company Ltd. (Fortitude Re), a wholly-owned subsidiary of Fortitude Holdings, in 2018 in a series of reinsurance transactions related to AIG’s Run-Off operations. As of December 31, 2020, approximately $ 30.5 billion of reserves from AIG’s Life and Retirement Run-Off Lines and approximately $ 4.1 billion of reserves from AIG’s General Insurance Run-Off Lines, related to business written by multiple wholly-owned AIG subsidiaries, had been ceded to Fortitude Re under these reinsurance transactions. As of closing of the Majority Interest Fortitude Sale, these reinsurance transactions are no longer considered affiliated transactions and Fortitude Re is the reinsurer of the majority of AIG’s Run-Off operations. As these reinsurance transactions are structured as modified coinsurance and loss portfolio transfers with funds withheld, following the closing of the Majority Interest Fortitude Sale, AIG continues to reflect the invested assets, which consist mostly of available for sale securities, supporting Fortitude Re’s obligations, in AIG’s financial statements. AIG sold a 19.9 percent ownership interest in Fortitude Holdings to TC Group Cayman Investments Holdings, L.P. (TCG), an affiliate of Carlyle, in November 2018 (the 2018 Fortitude Sale). As a result of completion of the Majority Interest Fortitude Sale, Carlyle FRL purchased from AIG a 51.6 percent ownership interest in Fortitude Holdings and T&D purchased from AIG a 25 percent ownership interest in Fortitude Holdings; AIG retained a 3.5 percent ownership interest in Fortitude Holdings and one seat on its Board of Managers. The $ 2.2 billion of proceeds received by AIG at closing include (i) the $ 1.8 billion under the Majority Interest Fortitude Sale, which is subject to a post-closing purchase price adjustment pursuant to which AIG will pay Fortitude Re for certain adverse development in property casualty related reserves, based on an agreed methodology, that may occur on or prior to December 31, 2023, up to a maximum payment of $ 500 million; and (ii) a $ 383 million purchase price adjustment from Carlyle FRL and T&D, corresponding to their respective portions of a proposed $ 500 million non-pro rata distribution from Fortitude Holdings that was not received by AIG prior to the closing. AIG recorded a total after-tax reduction to total AIG shareholders’ equity of $ 4.3 billion related to the sale of the majority interest in and deconsolidation of Fortitude Holdings in the second quarter of 2020. The impact to equity was primarily due to a $ 6.7 billion after-tax loss partially offset by a $ 2.4 billion increase in accumulated other comprehensive income (AOCI) due to the release of shadow adjustments primarily related to future policy benefits. The $ 6.7 billion after-tax loss was comprised of (i) a $ 2.7 billion loss related to the write-off of prepaid insurance assets and DAC upon deconsolidation of Fortitude Holdings and (ii) $ 4.0 billion related to the loss on the sale primarily as a result of increases in Fortitude Holdings’ equity principally related to mark to market movements from the December 31, 2018 date as of which Fortitude Holdings’ equity was calculated for purposes of the purchase price determination, through the June 2, 2020 closing date. In connection with the Majority Interest Fortitude Sale, AIG, Fortitude Holdings, and TCG agreed that, effective as of the closing, (i) AIG’s investment commitment targets under the 2018 Fortitude Sale (whereby AIG had agreed to invest certain amounts into various Carlyle strategies and to make certain minimum investment management fee payments by November 2021) were assumed by Fortitude Holdings and AIG was released therefrom, (ii) the purchase price adjustment that AIG had agreed to provide TCG in the 2018 Fortitude Sale (whereby AIG had agreed to reimburse TCG for adverse development in property casualty related reserves, based on an agreed methodology, that may occur on or prior to December 31, 2023, up to the value of TCG’s investment in Fortitude Holdings) has been terminated, and (iii) TCG remains obligated to pay AIG $ 115 million of deferred consideration upon settlement of the post-closing purchase price adjustment referred to above. This latter amount is composed of $ 95 million of deferred consideration contemplated as part of the 2018 Fortitude Sale, together with $ 19.9 million in respect of TCG’s 19.9 percent share of the unpaid portion of the $ 500 million non-pro rata dividend to be paid to AIG under the 2018 Fortitude Sale (TCG paid $ 79.6 million to AIG on May 26, 2020). In addition, the 2018 capital maintenance agreement between AIG and Fortitude Re and the letters of credit issued in support of Fortitude Re and subject to reimbursement by AIG in the event of a drawdown were terminated as of the closing of the Majority Interest Fortitude Sale. Upon closing of the Majority Interest Fortitude Sale, AIG entered into a transition services agreement with Fortitude Holdings for the provision of transition services for a period after closing, and letter of credit agreements with certain financial institutions, which issued letters of credit in support of certain General Insurance subsidiaries that have reinsurance agreements in place with Fortitude Re in the amount of $ 600 million. These letters of credit are subject to reimbursement by AIG in the event of a drawdown by these insurance subsidiaries. Following closing, in the second quarter of 2020, AIG contributed $ 700 million of the proceeds of the Majority Interest Fortitude Sale to certain of its General Insurance subsidiaries and $ 135 million of the proceeds of the Majority Interest Fortitude Sale to certain of its Life and Retirement subsidiaries. For further details on this transaction see Note 8 to the Consolidated Financial Statements. Blackboard At the end of March 2020, Blackboard U.S. Holdings, Inc. (Blackboard), AIG’s technology-driven subsidiary, was placed into run-off. As a result of this decision, during the three months ended March 31, 2020 and the year ended December 31, 2020, AIG recognized a pre-tax loss of $ 210 million, primarily consisting of asset impairment charges. Life and Retirement On October 26, 2020, AIG announced its intention to separate its Life and Retirement business from AIG. 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:  liability for unpaid losses and loss adjustment expenses (loss reserves);  valuation of future policy benefit liabilities and timing and extent of loss recognition;  valuation of liabilities for guaranteed benefit features of variable annuity products;  valuation of embedded derivatives for fixed index annuity and life products;  estimated gross profits to value deferred policy acquisition costs for investment-oriented products;  reinsurance assets, including the allowance for credit losses;  goodwill impairment;  allowances for credit losses primarily on loans and available for sale fixed maturity securities;  liability for legal contingencies;  fair value measurements of certain financial assets and liabilities; and  income tax assets and liabilities, including recoverability of our net deferred tax asset and the predictability of future tax operating profitability of the character necessary to realize the net deferred tax asset and estimates associated with the Tax Cuts and Jobs Act (the Tax Act). 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. Out of Period Adjustments For the year ended December 31, 2018, our results include out of period adjustments relating to prior periods that decreased net income attributable to AIG by $ 77 million, and decreased Income from continuing operations before income taxes by $ 98 million. The out of period adjustments are primarily related to decreases in deferred policy acquisition costs and increases in policyholder contract deposits. We determined that these adjustments were not material to 2018 or to any previously reported annual financial statements. REVISION OF PRIOR PERIOD FINANCIAL STATEMENTS During the fourth quarter of 2020, we identified certain cash flows that had been incorrectly classified in our Consolidated Statements of Cash Flows. Specifically, misclassifications were identified related to policyholder contract deposits that impacted several line items within the previously issued Consolidated Statements of Cash Flows. While these items affect the cash flows from operating and financing activities, they had no impact on the net increase (decrease) in cash and restricted cash for the previously reported periods. We assessed the materiality of the misclassification on prior period financial statements in accordance with SEC Staff Accounting Bulletin (SAB) Number 99, Materiality, as codified in ASC 250-10, Accounting Changes and Error Corrections. We have determined that these misclassifications were not material to the financial statements of any prior annual or interim period. Accordingly, the annual periods ended December 31, 2019 and 2018 have been corrected in the comparative Consolidated Statements of Cash Flows. Additionally, impacted prior interim periods will be revised within the Quarterly Report on Form 10-Q to be filed for the periods ending March 31, 2021, June 30, 2021, and September 30, 2021. For the year ended December 31, 2019, the unrealized (gains) losses in earnings – net and Insurance reserves line items in the Consolidated Statements of Cash Flows were adjusted by $( 1,513) million and $ 634 million, respectively. The total net cash provided by (used in) operating activities were adjusted by $( 879) million. Additionally, the Policyholder contract deposits and Policyholder contract withdrawals line items in the Consolidated Statements of Cash Flows were adjusted by $ 3,146 million and $( 2,267) million, respectively. The total net cash provided by financing activities was adjusted by $ 879 million. For the year ended December 31, 2018, the unrealized (gains) losses in earnings – net and Insurance reserves line items in the Consolidated Statements of Cash Flows were adjusted by $( 629) million and $ 174 million, respectively. The total net cash provided by (used in) operating activities were adjusted by $( 455) million. Additionally, the policyholder contract deposits and policyholder contract withdrawals line items in the Consolidated Statements of Cash Flows were adjusted by $ 3,142 million and $( 2,687) million, respectively. The total net cash provided by financing activities was adjusted by $ 455 million.

Earnings Per Common Share Note 22. Income Taxes Other significant accounting policies 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. Reinsurance premiums ceded under prospective reinsurance agreements are recognized as a reduction in revenues over the period the reinsurance coverage is provided in proportion to the risks to which the premiums relate. Reinsurance premiums for assumed business are estimated based on information received from brokers, ceding companies and reinsureds. Any subsequent differences that arise regarding such estimates are recorded in the periods in which they are determined. Premiums for long-duration insurance products and life contingent annuities are recognized as revenues when due. Estimates for premiums due but not yet collected are accrued. Policy fees represent fees recognized from universal life and investment-type products consisting of policy charges for the cost of insurance, policy administration charges, surrender charges and amortization of unearned revenue reserves. Policy fees are recognized as revenues in the period in which they are assessed against policyholders, unless the fees are designed to compensate AIG for services to be provided in the future. Fees deferred as unearned revenue are amortized in relation to the incidence of expected gross profits to be realized over the estimated lives of the contracts, similar to DAC. Other income includes advisory fee income from the Life and Retirement broker dealer business. Cash represents cash on hand and demand deposits. Short-term investments Short-term investments include highly liquid securities and other investments with remaining maturities of one year or less, but greater than three months, at the time of purchase. Securities included within short-term investments are stated at estimated fair value, while other investments included within short-term investments are stated at amortized cost, which approximates estimated fair value. Premiums and other receivables – net of allowance for credit losses and disputes include premium balances receivable, amounts due from agents and brokers and policyholders, trade receivables for the Direct Investment book (DIB) and Global Capital Markets (GCM) and other receivables. Trade receivables for GCM include cash collateral posted to derivative counterparties that is not eligible to be netted against derivative liabilities. The allowance for credit losses and disputes on premiums and other receivables was $ 205 million and $ 178 million at December 31, 2020 and 2019, respectively. Deposit assets and liabilities: We have entered into certain insurance and reinsurance contracts, primarily in our General Insurance companies, 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 Other 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 Other assets in the Consolidated Balance Sheets. The deposit asset or liability is adjusted as amounts are paid, consistent with the underlying contracts. Other assets consist of sales inducement assets, 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 assets of businesses classified as held-for-sale. We offer sales inducements which include enhanced crediting rates or bonus payments to contract holders (bonus interest) on certain annuity and investment contract products. Such amounts are deferred and amortized over the life of the contract using the same methodology and assumptions used to amortize DAC (see Note 9 herein) . To qualify for such accounting treatment, the bonus interest must be explicitly identified in the contract at inception. We must also demonstrate that such amounts are incremental to amounts we credit on similar contracts without bonus interest, and are higher than the contract’s expected ongoing crediting rates for periods after the bonus period. The deferred bonus interest and other deferred sales inducement assets totaled $ 281 million and $ 430 million at December 31, 2020 and 2019, respectively. The amortization expense associated with these assets is reported within Interest credited to policyholder account balances in the Consolidated Statements of Income. Such amortization expense totaled $ 60 million, $ 79 million and $ 156 million for the years ended December 31, 2020, 2019 and 2018, respectively. 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 equipment). 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. Separate accounts represent funds for which investment income and investment gains and losses accrue directly to the policyholders who bear the investment risk. Each account has specific investment objectives and the assets are carried at fair value. The assets of each account are legally segregated and are not subject to claims that arise from any of our other businesses. The liabilities for these accounts are equal to the account assets. Separate accounts may also include deposits for funds held under stable value wrap funding agreements, although the majority of stable value wrap sales are measured based on the notional amount included in assets under management and do not include the receipt of funds. For a more detailed discussion of separate accounts see Note 14 herein . Other liabilities consist of other funds on deposit, other payables, securities sold under agreements to repurchase, securities sold but not yet purchased, derivative liabilities, deferred gains on retroactive reinsurance agreements and liabilities of businesses classified as held-for-sale. Also included in Other liabilities are trade payables for the DIB and GCM, which include balances due to clearing brokers and exchanges. Trade payables for GCM also include cash collateral received from derivative counterparties that contractually cannot be netted against derivative assets. Securities sold but not yet purchased represent sales of securities not owned at the time of sale. The obligations arising from such transactions are recorded on a trade-date basis and carried at fair value. Fair values of securities sold but not yet purchased are based on current market prices. Foreign currency: Financial statement accounts expressed in foreign currencies are translated into U.S. dollars. Functional currency assets and liabilities are translated into U.S. dollars generally using rates of exchange prevailing at the balance sheet date of each respective subsidiary and the related translation adjustments are recorded as a separate component of Accumulated other comprehensive income, net of any related taxes, in Total AIG shareholders’ equity. Income statement accounts expressed in functional currencies are translated using average exchange rates during the period. Functional currencies are generally the currencies of the local operating environment. Financial statement accounts expressed in currencies other than the functional currency of a consolidated entity are remeasured into that entity’s functional currency resulting in exchange gains or losses recorded in income. The adjustments resulting from translation of financial statements of foreign entities operating in highly inflationary economies are recorded in income. Non-redeemable noncontrolling interest is the portion of equity (net assets) and net income (loss) in a subsidiary not attributable, directly or indirectly, to AIG. Accounting Standards Adopted During 2020 Financial Instruments – Credit Losses In June 2016, the FASB issued an accounting standard that changed how entities account for current expected credit losses (CECL) for most financial assets, premiums receivable, trade receivables, off-balance sheet exposures and reinsurance receivables (the Financial Instruments Credit Losses Standard). The standard requires an allowance for credit losses based on the expectation of lifetime credit losses related to such financial assets subject to credit losses, including loans measured at amortized cost, reinsurance receivables and certain off-balance sheet credit exposures. Additionally, the impairment of available-for-sale debt securities, including purchased credit deteriorated (PCD) securities, is subject to the new guidance and is measured in a similar manner, except that losses are recognized as allowances rather than reductions in the amortized cost of the securities. The standard allows for reversals of credit impairments in the event that the credit of an issuer improves. The standard also requires additional disclosures. We adopted the standard on its effective date of January 1, 2020 using a modified retrospective method, which requires a cumulative effect adjustment to retained earnings. As of January 1, 2020, the impact of the adoption of the standard was a reduction in opening retained earnings of $ 487 million (after-tax) primarily driven by commercial mortgage loans, and, to a lesser extent, reinsurance receivables and recoverables. The following table provides a rollforward of our allowance, including credit losses, in connection with the adoption of the Financial Instruments Credit Losses Standard as well as cross references to the applicable notes herein for additional information: Year Ended December 31, 2020 Balance, Cumulative Effect Purchased Credit Incremental Write-offs and Beginning Adjustment as of Deteriorated Initial Increase (Decrease) Other Changes Balance, (in millions) of Year January 1, 2020 Allowance Recognized in Income in the Allowance (h) End of Year Securities available for sale (a) $ - $ - $ 33 $ 280 $ ( 127) $ 186 Mortgage and other loan receivables (b) 438 318 - 75 ( 17) 814 Reinsurance recoverables (inclusive of deposit accounted assets) (c) 151 224 - 9 ( 9) 375 Premiums and other receivables (d) 178 34 - 6 ( 13) 205 Contractual deductible recoverables (e) - 14 - - - 14 Commercial mortgage loan commitments (f) - 51 - 28 - 79 Total $ 767 $ 641 $ 33 $ 398 $ ( 166) $ 1,673 Secondary impacts to certain long-duration insurance contracts (g) ( 27) Tax impact ( 127) Total cumulative effect adjustment $ 487 (a) The allowance for credit losses is reported in Bonds available for sale in the Consolidated Balance Sheets. Changes in the allowance for credit losses are reported in Net realized capital gains (losses) in the Consolidated Statements of Income. Refer to Note 6 for additional information. (b) The allowance for credit losses is reported in Mortgage and other loans receivable in the Consolidated Balance Sheets. Changes in the allowance for credit losses are reported in Net realized capital gains (losses) in the Consolidated Statements of Income. Refer to Note 7 for additional information. (c) The allowance for credit losses and disputes is reported in Reinsurance assets – other and Reinsurance assets – Fortitude Re for reinsurance contracts that contain sufficient insurance risk, and the allowance for credit losses is reported in Other assets for insurance and reinsurance contracts that do not contain sufficient insurance risk in the Consolidated Balance Sheets. Changes in the allowance for credit losses are reported in Policyholder benefits and losses incurred for reinsurance contracts that do contain sufficient insurance risk and premiums for contracts that do not contain sufficient insurance risk in the Consolidated Statements of Income. Refer to Note 8 for additional information. (d) The allowance for credit losses and disputes is reported in Premiums and other receivables in the Consolidated Balance Sheets. Changes in the allowance for credit losses and disputes are reported in General operating and other expenses in the Consolidated Statements of Income. Refer to Note 2 for additional information. (e) The allowance for credit losses is reported in Liability for unpaid losses and loss adjustment expenses in the Consolidated Balance Sheets. Changes in the allowance for credit losses are reported in Policyholder benefits and losses incurred in the Consolidated Statements of Income. Refer to Note 13 for additional information. (f) The allowance for credit losses is reported in Other liabilities in the Consolidated Balance Sheets. Changes in the allowance for credit losses are reported in Net realized capital gains (losses) in the Consolidated Statements of Income. Refer to Note 7 for additional information. (g) This reflects adjustments to the amortization of DAC, unearned revenue reserve and sales inducement assets as well as impacts on the future policy benefits for certain universal life and variable annuity contracts. (h) A write-off does not generally result in an incremental loss to AIG. Prior to a write-off occurring, the allowance for the credit loss is increased or decreased to reflect AIG’s expectation of the credit loss to be incurred. Accordingly, when a write-off occurs, the allowance is reversed for the same amount, resulting in no incremental loss to AIG. The following presents the impact of the adoption of the standard on premiums and other receivables. Premiums and other receivables – Credit Losses Premiums and other receivables, net of allowance for credit losses include premium balances receivable, amounts due from agents and brokers and policyholders, trade receivables for GCM and other receivables. Trade receivables for GCM include cash collateral posted to derivative counterparties that is not eligible to be netted against derivative liabilities. The allowance for credit losses and disputes for premiums and other receivables was $ 205 million at December 31, 2020. Our allowance for credit losses for premium receivables considers a combination of internal and external information relating to past events, current conditions and reasonable and supportable forecasts. Our allowance contemplates our contractual provisions. Upon default or delinquency of the policyholder we may be able to cease coverage for the remaining period. In certain jurisdictions we are unable to cancel coverage even in the event of delinquency or default by the policyholder. We consider premium and other receivable balances to be past due if the payment is not received after 90 days from the contractual obligation due date and record an allowance for disputes when there is reasonable uncertainty of the collectability of a disputed amount during the reporting period. For further information regarding the impacts of the adoption of this standard see Notes 6, 7, 8 and 13 to the Consolidated Financial Statements. Simplifying the Test for Goodwill Impairment In January 2017, the FASB issued an accounting standard that eliminates the requirement to calculate the implied fair value of goodwill, through a hypothetical purchase price allocation, to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on 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. An entity should also consider income tax effects from tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. We adopted the standard on its effective date of January 1, 2020. The adoption of the standard did not have a material impact on our financial position, results of operations or cash flows. Cloud Computing Arrangements In August 2018, the FASB issued an accounting standard that aligns the requirements for capitalizing implementation costs incurred in a cloud computing (or hosting) arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Capitalized implementation costs must be amortized over the term of the hosting arrangement. The accounting for the service element is not affected by the amendments in this update. We adopted the standard prospectively on its effective date of January 1, 2020. The adoption of the standard did not have a material impact on our consolidated financial position, results of operations or cash flows. Financial Disclosures About Guarantors and Issuers of Guaranteed Securities and Affiliates In March 2020, the Securities and Exchange Commission (SEC) adopted amendments to simplify and streamline the disclosure requirements for guarantors and issuers of guaranteed securities registered or being registered, and issuers’ affiliates whose securities collateralize securities registered or being registered. Currently, the SEC permits the omission of separate financial statements of subsidiary issuers and guarantors when certain conditions are met and the parent company provides summarized financial information of the subsidiary issuers and guarantors. The amendments, among other things, allow companies to cease providing summarized financial information if the subsidiary issuer’s or guarantor’s reporting obligation has been suspended. The amendments are effective January 4, 2021, with early adoption permitted. Effective March 31, 2020, AIG early adopted the amendment and ceased providing the summarized information for the subsidiary issuers and guarantors because the subsidiaries issuer’s reporting obligations have been suspended. Future Application of Accounting Standards Targeted Improvements to the Accounting for Long-Duration Contracts In August 2018, the FASB issued an accounting standard update with the objective of making targeted improvements to the existing recognition, measurement, presentation, and disclosure requirements for long-duration contracts issued by an insurance entity. The standard prescribes significant and comprehensive changes to recognition, measurement, presentation and disclosure as summarized below:  Requires the review and if necessary update of future policy benefit assumptions at least annually for traditional and limited pay long duration contracts, with the recognition and separate presentation of any resulting re-measurement gain or loss (except for discount rate changes as noted below) in the income statement.  Requires the discount rate assumption to be updated at the end of each reporting period using an upper medium grade (low-credit risk) fixed income instrument yield that maximizes the use of observable market inputs and recognizes the impact of changes to discount rates in other comprehensive income.  Simplifies the amortization of DAC to a constant level basis over the expected term of the related contracts with adjustments for unexpected terminations, but no longer requires an impairment test.  Requires the measurement of all market risk benefits associated with deposit (or account balance) contracts at fair value through the income statement with the exception of instrument-specific credit risk changes, which will be recognized in other comprehensive income.  Increased disclosures of disaggregated rollforwards of policy benefits, account balances, market risk benefits, separate account liabilities and information about significant inputs, judgments and methods used in measurement and changes thereto and impact of those changes. In November 2020, the FASB issued ASU 2020-11, which deferred the effective date of the standard for all entities. Our implementation efforts are underway for a January 1, 2023 effective date; we continue to evaluate the method of adoption and impact of the standard on our reported consolidated financial condition, results of operations, cash flows and required disclosures The adoption of this standard is expected to have a significant impact on our consolidated financial condition, results of operations, cash flows and required disclosures, as well as systems, processes and controls. Income Tax On December 18, 2019, the FASB issued an accounting standard that simplifies the accounting for income taxes by eliminating certain exceptions to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The amendments also simplified other areas including the accounting for franchise taxes and enacted tax laws or rates, and clarified the accounting for transactions that result in the step-up in the tax basis of goodwill. The standard is effective on January 1, 2021, with early adoption permitted. The impact is not material to our consolidated financial condition, results of operations and cash flows. Reference Rate Reform On March 12, 2020, the FASB issued an accounting standard that provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The standard allows us to account for certain contract modifications that result from the discontinuation of the London Inter-Bank Offered Rate (LIBOR) or another reference rate as a continuation of the existing contract without additional analysis. This guidance is not expected to have a significant impact on our consolidated financial statements and notes to the consolidated financial statements. Where applicable, we would account for the change for the modification due to the discontinuation of LIBOR or another reference rate as a continuation of the existing contract. As part of our implementation efforts, we will continue to assess our operational readiness and current and alternative reference rates’ merits, limitations, risks and suitability for our investment and insurance processes. This standard may be elected and applied prospectively over time from March 12, 2020 through December 31, 2022 as reference rate reform activities occur. We are evaluating the method of adoption and impact of the standard on our reported consolidated financial condition, results of operations, cash flows and required disclosures. Clarification of Accounting for Certain Equity Method Investments On January 16, 2020, the FASB issued an accounting standard to clarify how a previously issued standard regarding a company’s ability to measure the fair value of certain equity securities without a readily determinable fair value should interact with equity method investments standards. The previously issued standard provides that such equity securities could be measured at cost, minus impairment, if any, unless an observable transaction for an identical or similar security occurs (measurement alternative). The new standard clarifies that a company should consider observable transactions that require the company to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with the equity method immediately before applying or upon discontinuing the equity method. The standard further clarifies that, when determining the accounting for certain forward contracts and purchased options a company should not consider, whether upon settlement or exercise, if the underlying securities would be accounted for under the equity method or fair value option. The standard is effective for interim and annual reporting periods beginning after December 15, 2020. We do not expect the adoption of this standard to be material to our reported consolidated financial condition, results of operations, cash flows and required disclosures. GOODWILL Effective July 1, 2019, we changed the date of our annual goodwill impairment testing from December 31 to July 1. This change does not represent a material change to our method of applying current accounting guidance and is preferable as it better aligns with our strategic planning and forecasting process. This change did not delay, accelerate or avoid any impairment charge and was applied prospectively. We performed our annual goodwill impairment tests of all reporting units using a combination of both qualitative and quantitative assessments and concluded that our goodwill was not impaired. Our goodwill balance was $ 4.1 billion at December 31, 2020. For further information on goodwill see Note 12 to the Consolidated Financial Statements.

SEGMENT INFORMATION
SEGMENT INFORMATION	3. Segment Information We report our results of operations consistent with the manner in which our chief operating decision makers review the business to assess performance and allocate resources. Prior to the fourth quarter of 2020, we reported our results as follows:  General Insurance included our North America and International operating segments;  Life and Retirement included our Individual Retirement, Group Retirement, Life Insurance and Institutional Markets operating segments;  Other operations consisted primarily of businesses and items not allocated to our operating segments, amortization of value of distribution network acquired (VODA) related to the Validus and Glatfelter acquisitions and Interest expense attributable to AIG; and long-term debt as well as debt associated with consolidated investment entities; and  Legacy Portfolio included exited or discontinued product lines, policy forms or distribution channels. In the fourth quarter of 2020, our chief operating decision makers modified their view of our businesses and how they allocate resources and assess performance. Prior periods’ presentation has been revised to conform to our new structure. The new operating structure no longer includes a Legacy segment. We now report the results of our businesses as follows: General Insurance General Insurance business is presented as two operating segments:  North America – consists of insurance businesses in the United States, Canada, Bermuda, and our global reinsurance business, AIG Re. The results of Validus Reinsurance, Ltd., Western World Insurance Group, Inc. and Glatfelter were included as of their respective acquisition dates.  International – consists of regional 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 Holdings, Ltd (Talbot), as of its acquisition date, as well as AIG’s global specialty business. North America and International operating segments consist of the following products: – Commercial Lines – consists of Liability, Financial Lines, Property and Global Specialty. – Personal Insurance – consists of Personal Lines and Accident & Health. Life and Retirement Life and Retirement business is presented as four operating segments:  Individual Retirement – consists of fixed annuities, fixed index annuities, variable annuities and retail mutual funds.  Group Retirement – consists of group mutual funds, group annuities, individual annuity and investment products, financial planning and advisory services, and plan administrative and compliance services.  Life Insurance – primary products in the U.S. include term life and universal life insurance. International operations include distribution of life and health products in the UK and Ireland. Certain run-off life insurance portfolios previously reported in our Legacy segment have been realigned into the Life Insurance operating segment.  Institutional Markets – consists of stable value wrap products, structured settlement and pension risk transfer annuities, corporate- and bank-owned life insurance, and guaranteed investment contracts (GICs). The run-off high net worth (private placement variable universal life and private placement variable annuity) and structured settlement portfolios previously reported in our Legacy segment have been realigned into the Institutional Markets operating segment. On October 26, 2020, AIG announced its intention to separate its Life and Retirement business from AIG. Other Operations Other Operations primarily consists of income from assets held by AIG Parent and other corporate subsidiaries, deferred tax assets related to tax attributes, corporate expenses and intercompany eliminations, our institutional asset management business and results of our consolidated investment entities, General Insurance portfolios in run-off previously reported within Legacy as well as the historical results of our legacy insurance lines ceded to Fortitude Re. The accounting policies of the segments are the same as those described in Note 2. We evaluate segment performance based on adjusted revenues and adjusted pre-tax income (loss). Adjusted revenues and adjusted pre-tax income (loss) are derived by excluding certain items from total revenues and net income (loss) attributable to AIG, respectively. These items generally fall into one or more of the following broad categories: legacy matters having no relevance to our current businesses or operating performance; adjustments to enhance transparency to the underlying economics of transactions; and measures that we believe to be common to the industry. Legal entities are attributed to each segment based upon the predominance of activity in that legal entity. For the items excluded from adjusted revenues and adjusted pre-tax income (loss) see the table below.

BUSINESS COMBINATION
BUSINESS COMBINATION	4. Business Combination On July 18, 2018, we completed the purchase of a 100 percent voting interest in Validus, a leading provider of reinsurance, primary insurance, and asset management services, for $ 5.5 billion in cash. The purchase was accounted for under the acquisition method. Accordingly, the total purchase price was allocated to the estimated fair values of assets acquired and liabilities assumed. This allocation resulted in the purchase price exceeding the fair value of net assets acquired, which results in a difference recorded as goodwill. Goodwill generated from the acquisition is attributable to expected synergies from future growth and potential future monetization opportunities. Goodwill related to the purchase of Validus assigned to our General Insurance operating segments was $ 1.8 billion for North America and $ 157 million for International. In addition, Validus participates in the market for insurance-linked securities (ILS) primarily through AlphaCat Managers, Ltd (AlphaCat). AlphaCat is an asset manager primarily for third-party investors and in connection with the issuance of ILS invests in AlphaCat funds which are considered VIEs. ILS are financial instruments for which the values are determined based on insurance losses caused primarily by natural catastrophes such as major earthquakes and hurricanes. We report the investment in AlphaCat funds, which is approximately $ 118 million and $ 124 million at December 31, 2020 and December 31, 2019, respectively, in Other Invested Assets in the Consolidated Balance Sheets. The following unaudited summarized pro forma consolidated income statement information assumes that the acquisition of Validus occurred as of January 1, 2017. The pro forma amounts are for comparative purposes only and may not necessarily reflect the results of operations that would have resulted had the acquisition been completed at the beginning of the applicable period and may not be indicative of the results that will be attained in the future. Year Ended December 31, (dollars in millions, except per common share data) 2018* Total revenues $ 48,588 Net income 16 Net loss attributable to AIG common shareholders ( 51) Loss per common share attributable to AIG common shareholders: Basic: Net loss attributable to AIG common shareholders ( 0.06) Diluted: Net loss attributable to AIG common shareholders ( 0.06) * Pro forma adjustments were made to Validus’ external reporting results prior to the acquisition date for the deconsolidation of certain asset management entities consistent with AIG’s post acquisition accounting, which had no impact on Net income attributable to Validus.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	12 Months Ended

FAIR VALUE MEASUREMENTS
FAIR VALUE MEASUREMENTS	5. Fair Value Measurements Fair Value Measurements on a Recurring Basis We carry certain of our financial instruments at fair value. We define the fair value of a financial instrument as the amount that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We are responsible for the determination of the value of the investments carried at fair value and the supporting methodologies and assumptions. The degree of judgment used in measuring the fair value of financial instruments generally inversely correlates with the level of observable valuation inputs. We maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Financial instruments with quoted prices in active markets generally have more pricing observability and less judgment is used in measuring fair value. Conversely, financial instruments for which no quoted prices are available have less observability and are measured at fair value using valuation models or other pricing techniques that require more judgment. Pricing observability is affected by a number of factors, including the type of financial instrument, whether the financial instrument is new to the market and not yet established, the characteristics specific to the transaction, liquidity and general market conditions. Fair Value Hierarchy Assets and liabilities recorded at fair value in the Consolidated Balance Sheets are measured and classified in accordance with a fair value hierarchy consisting of three “levels” based on the observability of valuation inputs:  Level 1: Fair value measurements based on quoted prices (unadjusted) in active markets that we have the ability to access for identical assets or liabilities. Market price data generally is obtained from exchange or dealer markets. We do not adjust the quoted price for such instruments.  Level 2: Fair value measurements based on inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals.  Level 3: Fair value measurements based on valuation techniques that use significant inputs that are unobservable. Both observable and unobservable inputs may be used to determine the fair values of positions classified in Level 3. The circumstances for using these measurements include those in which there is little, if any, market activity for the asset or liability. Therefore, we must make certain assumptions about the inputs a hypothetical market participant would use to value that asset or liability. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The following is a description of the valuation methodologies used for instruments carried at fair value. These methodologies are applied to assets and liabilities across the levels discussed above, and it is the observability of the inputs used that 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. For a description of how we incorporate our own credit risk in the valuation of embedded derivatives related to certain annuity and life insurance products see – Embedded Derivatives within Policyholder Contract Deposits below.  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 benchmark LIBOR 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 are applied to the fair values received from independent third-party valuation service providers to ensure the accuracy of these values. 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. 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 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 debt obligations (CDO), 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. 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. Separate Account Assets Separate account assets are composed primarily of registered and unregistered open-end mutual funds that generally trade daily and are measured at fair value in the manner discussed above for equity securities traded in active markets. 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. Embedded Derivatives within Policyholder Contract Deposits Certain variable annuity and equity-indexed annuity and life contracts contain embedded derivatives that we bifurcate from the host contracts and account for separately at fair value, with changes in fair value recognized in earnings. These embedded derivatives are classified within Policyholder contract deposits. We have concluded these contracts contain either (i) a written option that guarantees a minimum accumulation value at maturity, (ii) a written option that guarantees annual withdrawals regardless of underlying market performance for a specific period or for life, or (iii) equity-indexed written options that meet the criteria of derivatives and must be bifurcated. The fair value of embedded derivatives contained in certain variable annuity and equity-indexed annuity and life contracts is measured based on policyholder behavior and capital market assumptions related to projected cash flows over the expected lives of the contracts. These discounted cash flow projections primarily include benefits and related fees assessed, when applicable. In some instances, the projected cash flows from fees may exceed projected cash flows related to benefit payments and therefore, at a point in time, the carrying value of the embedded derivative may be in a net asset position. The projected cash flows incorporate best estimate assumptions for policyholder behavior (including mortality, lapses, withdrawals and benefit utilization), along with an explicit risk margin to reflect a market participant’s estimates of projected cash flows and policyholder behavior. Estimates of future policyholder behavior assumptions are subjective and based primarily on our historical experience. Because of the dynamic and complex nature of the projected cash flows with respect to embedded derivatives in our variable annuity contracts, risk neutral valuations are used, which are calibrated to observable interest rate and equity option prices. Estimating the underlying cash flows for these products involves judgments regarding the capital market assumptions related to expected market rates of return, market volatility, credit spreads, correlations of certain market variables, fund performance and discount rates. Additionally, estimating the underlying cash flows for these products also involves judgments regarding policyholder behavior. The portion of fees attributable to the fair value of expected benefit payments are included within the fair value measurement of these embedded derivatives, and related fees are classified in net realized gain/loss as earned, consistent with other changes in the fair value of these embedded policy derivatives. Any portion of the fees not attributed to the embedded derivatives are excluded from the fair value measurement and classified in policy fees as earned. With respect to embedded derivatives in our equity-indexed annuity and life contracts, option pricing models are used to estimate fair value, taking into account the capital market assumptions for future equity index growth rates, volatility of the equity index, future interest rates, and our ability to adjust the participation rate and the cap on equity-indexed credited rates in light of market conditions and policyholder behavior assumptions. Projected cash flows are discounted using the interest rate swap curve (swap curve), which is commonly viewed as being consistent with the credit spreads for highly-rated financial institutions (S&P AA-rated or above). A swap curve shows the fixed-rate leg of a non-complex swap against the floating rate (for example, LIBOR) leg of a related tenor. We also incorporate our own risk of non-performance in the valuation of the embedded derivatives associated with variable annuity and equity-indexed annuity and life contracts. The non-performance risk adjustment (NPA) reflects a market participant’s view of our claims-paying ability by incorporating an additional spread to the swap curve used to discount projected benefit cash flows in the valuation of these embedded derivatives. The non-performance risk adjustment is calculated by constructing forward rates based on a weighted average of observable corporate credit indices to approximate the claims-paying ability rating of our Life and Retirement companies. Fortitude Re funds withheld payable The reinsurance transactions between AIG and Fortitude Re were structured as modified coinsurance (modco) and loss portfolio transfer arrangements with funds withheld (funds withheld). As a result of the deconsolidation resulting from the Majority Interest Fortitude Sale, 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 capital 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. 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. Long-Term Debt The fair value of non-structured liabilities is generally determined by using market prices from exchange or dealer markets, when available, or discounting expected cash flows using the appropriate discount rate for the applicable maturity. We determine the fair value of structured liabilities and hybrid financial instruments (where performance is linked to structured interest rates, inflation or currency risks) using the appropriate derivative valuation methodology (described above) given the nature of the embedded risk profile. In addition, adjustments are made to the valuations of both non-structured and structured liabilities to reflect our own creditworthiness based on the methodology described under the caption “Incorporation of Credit Risk in Fair Value Measurements – Our Own Credit Risk” above. Borrowings under obligations of guaranteed investment agreements (GIAs), which are guaranteed by us, are recorded at fair value using discounted cash flow calculations based on interest rates currently being offered for similar contracts and our current market observable implicit credit spread rates with maturities consistent with those remaining for the contracts being valued. Obligations may be called at various times prior to maturity at the option of the counterparty. Interest rates on these borrowings are primarily fixed, vary by maturity and range up to 7.15 percent. 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.

Investments Fixed Maturity Securities Subsequent to the adoption of the Financial Instruments Credit Losses Standard on January 1, 2020 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 are measured at fair value at our election. None of our fixed maturity securities met the criteria for held to maturity classification at December 31, 2020 or 2019. 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 policy related amounts and deferred income taxes, in shareholders’ equity. Realized and unrealized gains and losses from fixed maturity securities measured at fair value at our election 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 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. Prior to the adoption of the Financial Instruments Credit Losses Standard on January 1, 2020 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 RMBS, CMBS and CDO/ABS, (collectively, 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, effective yields are recalculated and adjusted prospectively based on changes in expected undiscounted future cash flows. For purchased credit impaired (PCI) securities, at acquisition, the difference between the undiscounted expected future cash flows and the recorded investment in the securities represents the initial accretable yield, which is to be accreted into net investment income over the securities’ remaining lives on an effective level-yield basis. Subsequently, effective yields recognized on PCI securities are recalculated and adjusted prospectively to reflect changes in the contractual benchmark interest rates on variable rate securities and any significant increases in undiscounted expected future cash flows arising due to reasons other than interest rate changes.

At December 31, 2019, we held 5,695 individual fixed maturity securities that were in an unrealized loss position, of which 1,254 individual fixed maturity securities were in a continuous unrealized loss position for 12 months or more. We did not recognize the unrealized losses in earnings on these fixed maturity securities at December 31, 2020 because it was determined that such losses were due to non-credit factors. Additionally, we neither intend to sell the securities nor do we believe that it is more likely than not that we will be required to sell these securities before recovery of their amortized cost basis. For fixed maturity securities with significant declines, we performed fundamental credit analyses on a security-by-security basis, which included consideration of credit enhancements, liquidity position, expected defaults, industry and sector analysis, forecasts and available market data. Contractual Maturities of Fixed Maturity Securities Available for Sale The following table presents the amortized cost and fair value of fixed maturity securities available for sale by contractual maturity: Total Fixed Maturity Securities Available for Sale Amortized Cost, (in millions) Net of Allowance Fair Value December 31, 2020 Due in one year or less $ 10,619 $ 10,734 Due after one year through five years 43,405 45,248 Due after five years through ten years 40,927 45,241 Due after ten years 86,778 103,670 Mortgage-backed, asset-backed and collateralized 62,422 66,603 Total $ 244,151 $ 271,496 Actual maturities may differ from contractual maturities because certain borrowers have the right to call or prepay certain obligations with or without call or prepayment penalties.

Included within the net realized capital gains (losses) is $ 707 million of realized capital gains for the year ended December 31, 2020, which relate to the Fortitude Re funds withheld assets held by AIG in support of Fortitude Re’s reinsurance obligations to AIG (Fortitude Re funds withheld assets) for the period after deconsolidation of Fortitude Re. These realized capital gains are included in Net realized capital gains (losses) on Fortitude Re funds withheld assets. For the years ended December 31, 2019 and 2018, the aggregate fair value of available for sale securities sold was $ 22.0 billion and $ 25.1 billion, respectively, which resulted in net realized capital gains (losses) of $ 320 million and $( 129) million, respectively.

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, affordable housing partnerships 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. Summarized Financial Information of Equity Method Investees The following is the aggregated summarized financial information of our equity method investees, including those for which the fair value option has been elected: Years Ended December 31, (in millions) 2020 2019 2018 Operating results: Total revenues $ 13,090 $ 8,045 $ 15,310 Total expenses ( 2,897) ( 3,115) ( 3,200) Net income $ 10,193 $ 4,930 $ 12,110 At December 31, (in millions) 2020 2019 Balance sheet: Total assets $ 85,083 $ 93,773 Total liabilities $ ( 10,462) $ ( 14,218) The following table presents the carrying amount and ownership percentage of equity method investments at December 31, 2020 and 2019: 2020 2019 Carrying Ownership Carrying Ownership (in millions) Value Percentage Value Percentage Equity method investments $ 4,548 Various $ 5,911 Various Summarized financial information for these equity method investees may be presented on a lag, due to the unavailability of information for the investees at our respective balance sheet dates, and is included for the periods in which we held an equity method ownership interest. Other Investments Also included in Other invested assets are real estate held for investment. These investments are reported at cost, less depreciation and are subject to impairment review, as discussed below. Net Investment Income Net investment income represents income primarily from the following sources:  Interest income and related expenses, including amortization of premiums and accretion of discounts with changes in the timing and the amount of expected principal and interest cash flows reflected in yield, as applicable.  Dividend income from common and preferred stocks.  Realized and unrealized gains and losses from investments in other securities and investments for which we elected the fair value option.  Earnings from alternative investments.  Prepayment premiums.

Change in Unrealized Appreciation (Depreciation) of Investments The following table presents the increase (decrease) in unrealized appreciation (depreciation) of our available for sale securities and other investments: Years Ended December 31, (in millions) 2020 2019 Increase (decrease) in unrealized appreciation (depreciation) of investments: Fixed maturity securities $ 9,489 $ 14,245 Other investments 2 ( 70) Total increase (decrease) in unrealized appreciation (depreciation) of investments * $ 9,491 $ 14,175 * Excludes net unrealized gains and losses attributable to businesses held for sale at December 31, 2019.

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 realized capital 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 accumulated other comprehensive income). 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, CDO, 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. Credit losses are reassessed each period. The allowance for credit losses and the corresponding charge to realized capital 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 decreasing realized capital losses. Prior to the adoption of the Financial Instruments Credit Losses Standard on January 1, 2020 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 the fair value of the security is below amortized cost, an other-than-temporary impairment has occurred and the amortized cost is written down to current fair value, with a corresponding charge to realized capital losses. 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 credit impairment has occurred, the amortized cost is written down to the estimated recoverable value with a corresponding charge to realized capital losses. 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 related to a credit impairment is presented in unrealized appreciation (depreciation) of fixed maturity securities on which other-than-temporary credit impairments were recognized (a separate component of accumulated other comprehensive income). 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. In periods subsequent to the recognition of an other-than-temporary impairment charge for available for sale fixed maturity securities that is not foreign exchange related, we prospectively accrete into earnings the difference between the new amortized cost and the expected undiscounted recoverable value over the remaining expected holding period of the security. Credit Impairments The following table presents a rollforward of the changes in allowance for credit losses on available for sale fixed maturity securities by major investment category: Year Ended December 31, 2020 Non- (in millions) Structured Structured Total Balance, beginning of year* $ 7 $ - $ 7 Additions: Securities for which allowance for credit losses were not previously recorded 38 290 328 Purchases of available for sale debt securities accounted for as purchased credit deteriorated assets 26 - 26 Accretion of available for sale debt securities accounted for as purchased credit deteriorated assets 1 - 1 Reductions: Securities sold during the period ( 5) ( 26) ( 31) Intent to sell security or more likely than not will be required to sell the security before recovery of its amortized cost basis - - - Additional net increases or decreases to the allowance for credit losses on securities that had an allowance recorded in a previous period, for which there was no intent to sell before recovery amortized cost basis ( 50) 33 ( 17) Write-offs charged against the allowance - ( 128) ( 128) Recoveries of amounts previously written off - - - Other - - - Balance, end of year $ 17 $ 169 $ 186 * The beginning balance incorporates the Day 1 gross up on PCD assets held as of January 1, 2020.

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 aircraft assets and 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. We sold the remaining portion of our aircraft assets in 2018. Purchased Credit Deteriorated/Impaired Securities Subsequent to the adoption of the Financial Instruments Credit Los

LENDING ACTIVITIES
LENDING ACTIVITIES	7. Lending Activities Mortgage and other loans receivable include commercial mortgages, residential mortgages, life insurance policy loans, commercial loans, and other loans and notes receivable. Commercial mortgages, residential 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. Premiums and discounts on purchased residential mortgages are also 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. Interest income is not accrued when payment of contractual principal and interest is not expected. Any cash received on impaired loans is generally recorded as a reduction of the current carrying amount of the loan. Accrual of interest income is generally resumed when delinquent contractual principal and interest is repaid or when a portion of the delinquent contractual payments are made and the ongoing required contractual payments have been made for an appropriate period. As of December 31, 2020, $ 14 million and $ 238 million of residential mortgage loans and commercial mortgage loans, respectively, were placed on nonaccrual status. Accrued interest is presented separately and is included in Other assets 14 million and $ 129 million associated with residential mortgage loans and commercial mortgage loans, respectively. A significant majority of commercial mortgages in the portfolio are non-recourse loans and, accordingly, the only guarantees are for specific items that are exceptions to the non-recourse provisions. It is therefore extremely rare for us to have cause to enforce the provisions of a guarantee on a commercial real estate or mortgage loan. The following table presents the composition of Mortgage and other loans receivable, net: December 31, December 31, (in millions) 2020 2019 Commercial mortgages (a) $ 36,424 $ 36,170 Residential mortgages 4,645 6,683 Life insurance policy loans 1,986 2,065 Commercial loans, other loans and notes receivable 3,321 2,504 Total mortgage and other loans receivable 46,376 47,422 Allowance for credit losses (b) ( 814) ( 438) Mortgage and other loans receivable, net $ 45,562 $ 46,984 (a) Commercial mortgages primarily represent loans for apartments, offices and retail properties, with exposures in New York and California representing the largest geographic concentrations (aggregating approximately 24 percent and 10 percent, respectively, at December 31, 2020, and 23 percent and 10 percent, respectively, at December 31, 2019). (b) Does not include $ 79 million of expected credit loss liability at December 31, 2020 in relation to off-balance-sheet commitments to fund commercial mortgage loans, which is recorded in Other liabilities. Nonperforming loans are generally those loans where payment of contractual principal or interest is more than 90 days past due. Nonperforming loans were not significant for any of the periods presented.

Methodology Used to Estimate the Allowance for Credit Losses Subsequent to the adoption of the Financial Instruments Credit Losses Standard on January 1, 2020 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 capital losses. This allowance reflects the risk of loss, even when that risk is remote, and reflects losses 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 and residential 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, FICO 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 capital gains (losses) in the Consolidated Statements of Income. Prior to the adoption of the Financial Instruments Credit Losses Standard on January 1, 2020 Mortgage and other loans receivable are considered impaired when collection of all amounts due under contractual terms is not probable. Impairment is measured using either i) the present value of expected future cash flows discounted at the loan’s effective interest rate, ii) the loan’s observable market price, if available, or iii) the fair value of the collateral if the loan is collateral dependent. Impairment of commercial mortgages is typically determined using the fair value of collateral while impairment of other loans is typically determined using the present value of cash flows or the loan’s observable market price. An allowance is typically established for the difference between the impaired value of the loan and its current carrying amount. Additional allowance amounts are established for incurred but not specifically identified impairments, based on statistical models primarily driven by past-due status, debt service coverage, loan-to-value ratio, property type and location, loan term, profile of the borrower and of the major property tenants, and loan seasoning. When all or a portion of a loan is deemed uncollectable, the uncollectable portion of the carrying amount of the loan is charged off against the allowance. The following table presents a rollforward of the changes in the allowance for losses on Mortgage and other loans receivable (a) Years Ended December 31, 2020 2019 2018 Commercial Other Commercial Other Commercial Other (in millions) Mortgages Loans Total Mortgages Loans Total Mortgages Loans Total Allowance, beginning of year $ 336 $ 102 $ 438 $ 318 $ 79 $ 397 $ 247 $ 75 $ 322 Initial allowance upon CECL adoption 311 7 318 - - - - - - Loans charged off ( 12) ( 5) ( 17) ( 2) ( 3) ( 5) ( 17) ( 2) ( 19) Recoveries of loans previously charged off - - - - - - - 1 1 Net charge-offs ( 12) ( 5) ( 17) ( 2) ( 3) ( 5) ( 17) ( 1) ( 18) Provision for loan losses 50 25 75 20 26 46 88 5 93 Allowance, end of year $ 685 $ 129 $ 814 $ 336 (b) $ 102 $ 438 $ 318 (b) $ 79 $ 397 (a) Does not include $ 79 million of expected credit loss liability at December 31, 2020 in relation to off-balance-sheet commitments to fund commercial mortgage loans, which is recorded in Other liabilities. (b) The December 31, 2019 and 2018 total allowance was calculated prior to the adoption of ASC 326 on January 1, 2020. Of the total allowance, $ 10 million and $ 3 million relates to individually assessed credit losses on $ 148 million and $ 54 million of commercial mortgages at December 31, 2019 and 2018, respectively. As a result of the COVID-19 crisis, including the significant global economic slowdown and general market decline, our expectations and models used to estimate the allowance for losses on commercial and residential mortgage loans have been updated to reflect the current economic environment. The full impact of COVID-19 on real estate valuations remains uncertain and we will continue to review our valuations as further information becomes available. Troubled Debt Restructurings We modify loans to optimize their returns and improve their collectability, among other things. When we undertake such a modification with a borrower that is experiencing financial difficulty and the modification involves us granting a concession to the troubled debtor, the modification is a troubled debt restructuring (TDR). 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. Concessions granted may include extended maturity dates, interest rate changes, principal or interest forgiveness, payment deferrals and easing of loan covenants. In response to the COVID-19 pandemic, there was an increase in the volume of loan modifications in our commercial mortgage, residential mortgage and leveraged loan portfolios. The COVID-19 related modifications were primarily in the form of short-term payment deferrals (one to six months). Short-term payment deferrals are not considered a concession and therefore these modifications are not considered a TDR. During the years ended December 31, 2020 and 2019, loans with a carrying value of $ 106 million and $ 86 million, respectively, were modified in TDRs.

REINSURANCE

REINSURANCE
REINSURANCE	8. Reinsurance In the ordinary course of business, our insurance companies may use both treaty and facultative reinsurance to minimize their net loss exposure to any single catastrophic loss event or to an accumulation of losses from a number of smaller events or to provide greater diversification of our businesses. In addition, our General Insurance subsidiaries assume reinsurance from other insurance companies. We determine the portion of the incurred but not reported (IBNR) loss that will be recoverable under our reinsurance contracts by reference to the terms of the reinsurance protection purchased. This determination is necessarily based on the estimate of IBNR and accordingly, is subject to the same uncertainties as the estimate of IBNR. Reinsurance assets include the balances due from reinsurance and insurance companies under the terms of our reinsurance agreements for paid and unpaid losses and loss adjustment expenses incurred, 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 unpaid losses and benefits and loss expenses with respect to these reinsurance agreements are substantially collateralized. We remain liable to the extent that our reinsurers do not meet their obligation 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 credit losses and disputes requires judgment for which key inputs typically include historical trends regarding uncollectible balances, disputes and credit events 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 $ 326 million and $ 151 million at December 31, 2020 and 2019, respectively. Changes in the allowance for credit losses and disputes on reinsurance assets are reflected in Policyholder benefits and losses incurred within the Consolidated Statements of Income. The following table provides supplemental information for loss and benefit reserves, gross and net of ceded reinsurance: At December 31, 2020 2019 As Net of As Net of (in millions) Reported Reinsurance Reported Reinsurance Liability for unpaid losses and loss adjustment expenses $ ( 77,720) $ ( 43,154) $ ( 78,328) $ ( 47,259) Future policy benefits for life and accident and health insurance contracts ( 51,097) ( 25,121) ( 50,512) ( 49,670) Policyholder contract deposits ( 160,251) ( 155,072) ( 151,869) ( 150,944) Reserve for unearned premiums ( 18,660) ( 14,606) ( 18,269) ( 15,067) Other policyholder funds ( 3,548) ( 2,933) ( 3,428) ( 3,420) Reinsurance assets (a) 70,390 36,046 (a) Reinsurance assets excludes (i) allowance for credit losses and disputes of $ 326 million (of which $ 135 million pertains to CECL reserve for Liability for unpaid losses and loss adjustment expenses) and $ 151 million for the years ended December 31, 2020 and 2019, respectively, (ii) paid loss recoveries of $ 3,157 million and $ 1,970 million for the years ended December 31, 2020 and 2019, respectively, and (iii) policy and contract claims recoverable of $ 320 million and $ 112 million for the years ended December 31, 2020 and 2019, respectively. Short-Duration Reinsurance Short-duration reinsurance is effected under reinsurance treaties and by negotiation on individual risks. Certain of these reinsurance arrangements consist of excess of loss contracts that protect us against losses above stipulated amounts. Ceded premiums are considered prepaid reinsurance premiums and are recognized as a reduction of premiums earned over the contract period in proportion to the protection received. Amounts recoverable from reinsurers on short-duration contracts are estimated in a manner consistent with the claims liabilities associated with the reinsurance and presented as a component of Reinsurance assets. Reinsurance premiums for assumed business are estimated based on information received from brokers, ceding companies and reinsurers. Any subsequent differences arising on such estimates are recorded in the periods in which they are determined. Assumed reinsurance premiums are earned primarily on a pro-rata basis over the terms of the reinsurance contracts and the portion of premiums relating to the unexpired terms of coverage is included in the reserve for unearned premiums. Reinsurance premiums for assumed business are estimated based on information received from brokers, ceding companies and reinsureds. Any subsequent differences arising on such estimates are recorded in the periods in which they are determined. For both ceded and assumed reinsurance, risk transfer requirements must be met for reinsurance accounting to apply. If risk transfer requirements are not met, the contract is accounted for as a deposit, resulting in the recognition of cash flows under the contract through a deposit asset or liability and not as revenue or expense. To meet risk transfer requirements, a reinsurance contract must include both insurance risk, consisting of both underwriting and timing risk, and a reasonable possibility of a significant loss for the assuming entity. Similar risk transfer criteria are used to determine whether directly written insurance contracts should be accounted for as insurance or as a deposit. The following table presents short-duration insurance premiums written and earned: Years Ended December 31, (in millions) 2020 2019 2018 Premiums written: Direct $ 28,521 $ 29,338 $ 30,368 Assumed 5,947 5,808 4,186 Ceded ( 11,012) ( 9,692) ( 7,757) Net $ 23,456 $ 25,454 $ 26,797 Premiums earned: Direct $ 28,596 $ 30,017 $ 31,450 Assumed 5,984 6,395 4,638 Ceded ( 10,435) ( 9,526) ( 8,164) Net $ 24,145 $ 26,886 $ 27,924 For the years ended December 31, 2020, 2019 and 2018, reinsurance recoveries, which reduced losses and loss adjustment expenses incurred, amounted to $ 7.7 billion, $ 4.7 billion and $ 9.8 billion, respectively. Retroactive reinsurance agreements are reinsurance agreements under which our reinsurer agrees to reimburse us as a result of past insurable events. For these agreements, the excess of the amounts ultimately collectible under the agreement over the consideration paid is recognized as a deferred gain liability and amortized into income over the settlement period of the ceded reserves. The amount of the deferral is recalculated each period based on loss payments and updated estimates. If the consideration paid exceeds the ultimate losses collectible under the agreement, the net loss on the agreement is recognized in income immediately. Ceded loss reserves under retroactive agreements were $ 18.9 billion and $ 13.9 billion, and the deferred gain liability was $ 1.7 billion and $ 1.8 billion, as of December 31, 2020 and 2019, respectively. The effect on income from amortization of the deferred gain was $ 237 million, $ 219 million and $ 394 million for the years ended December 31, 2020, 2019 and 2018, respectively. In the first quarter of 2017, we entered into an adverse development reinsurance agreement with National Indemnity Company (NICO), a subsidiary of Berkshire Hathaway Inc., under which we transferred to NICO 80 percent of the reserve risk on substantially all of our U.S. Commercial long-tail exposures for accident years 2015 and prior. Under this agreement, we ceded to NICO 80 percent of the losses on subject business paid on or after January 1, 2016 in excess of $ 25 billion of net paid losses, up to an aggregate limit of $ 25 billion. We account for this transaction as retroactive reinsurance. This transaction resulted in a gain, which under U.S. GAAP retroactive reinsurance accounting is deferred and amortized into income over the settlement period. NICO created a collateral trust account as security for their claim payment obligations to us, into which they deposited the consideration paid under the agreement, and Berkshire Hathaway Inc. has provided a parental guarantee to secure NICO’s obligations under the agreement. Long-Duration Reinsurance Long-duration reinsurance is effected principally under yearly renewable term (YRT) treaties, along with a large modco treaty with a former affiliate, Fortitude Re, that was deconsolidated following the Majority Interest Fortitude Sale. This modco treaty reinsures the majority of our long-duration run-off business. The premiums with respect to YRT treaties are earned over the contract period in proportion to the protection provided, while ceded premiums related to modco treaties are recognized when due. Amounts recoverable on YRT treaties are recognized when claims are incurred on the reinsured policies and are presented as a component of reinsurance assets. Amounts recoverable on the modco treaty are estimated in a manner consistent with the assumptions used for the underlying policy benefits and are presented as a separate reinsurance asset. The following table presents premiums earned and policy fees for our long-duration life insurance and annuity operations: Years Ended December 31, (in millions) 2020 2019 2018 Premiums Direct $ 4,381 $ 4,363 $ 3,489 Assumed 1,058 228 56 Ceded ( 1,061) ( 916) ( 855) Net $ 4,378 $ 3,675 $ 2,690 Policy Fees Direct $ 2,957 $ 3,016 $ 2,792 Assumed - - - Ceded ( 40) ( 1) ( 1) Net $ 2,917 $ 3,015 $ 2,791 Long-duration reinsurance recoveries, which reduced Policyholder benefits and losses incurred, was approximately $ 1.1 billion, $ 1.0 billion and $ 778 million for the years ended December 31, 2020, 2019 and 2018, respectively. The following table presents long-duration insurance in-force ceded to other insurance companies: At December 31, (in millions) 2020 2019 2018 Long-duration insurance in force ceded $ 292,517 $ 264,732 $ 228,846 Long-duration insurance in-force assumed as a percentage of gross long-duration insurance in-force was 0.02 percent, 0.02 percent, and 0.03 percent at December 31, 2020, 2019 and 2018, respectively; and premiums assumed represented 19.5 percent, 5 percent and 1.6 percent of gross premiums for the years ended December 31, 2020, 2019 and 2018, respectively. The U.S. Life and Retirement companies manage the capital impact of their statutory reserve requirements, including those resulting from the National Association of Insurance Commissioners (NAIC) Model Regulation “Valuation of Life Insurance Policies” (Regulation XXX) and NAIC Actuarial Guideline 38 (Guideline AXXX), through unaffiliated and affiliated reinsurance transactions. Effective July 1, 2016, one of the U.S. Life and Retirement companies entered into an agreement to cede approximately $ 5 billion of statutory reserves for certain whole life and universal life policies to an unaffiliated reinsurer. Effective December 31, 2016, the same life insurance subsidiary recaptured term and universal life reserves subject to Regulation XXX and Guideline AXXX, previously ceded to an affiliate, and ceded approximately $ 14 billion of such statutory reserves to an unaffiliated reinsurer under an amendment to the December 31, 2016 agreement. Under U.S. GAAP, these unaffiliated reinsurance transactions use deposit accounting with a reinsurance risk charge recorded in income, whereas such affiliated transactions are eliminated in consolidation. Under one affiliated reinsurance arrangement, one of the U.S. Life and Retirement companies obtains letters of credit to support statutory recognition of the ceded reinsurance. As of December 31, 2020, this subsidiary had a bilateral letter of credit totaling $ 250 million, which was issued on February 7, 2014 and expires on February 7, 2024. The letter of credit is subject to reimbursement by AIG Parent in the event of a drawdown. In addition, a domestic life insurance subsidiary domiciled in Texas further manages the capital impact of statutory reserve requirements related to fixed index annuities with guaranteed living benefits through two unaffiliated excess of loss reinsurance agreements effective December 31, 2019 and 2020, respectively. Pursuant to a permitted statutory accounting practice, the subsidiary recognizes an admitted asset of approximately $ 0.6 billion related to the notional value of coverage defined in the excess of loss reinsurance agreements, net of specified amounts. Under U.S. GAAP, an asset will only be recognized if claims accumulate in an amount in excess of the attachment point specified in the agreements. For additional information on the use of affiliated reinsurance for Regulation XXX and Guideline AXXX reserves see Note 19. Sale of Fortitude Holdings On June 2, 2020, we completed the Majority Interest Fortitude Sale. AIG established Fortitude Re, a wholly-owned subsidiary of Fortitude Holdings, in 2018 in a series of reinsurance transactions related to AIG’s Run-Off operations. As of December 31, 2020, approximately $ 30.5 billion of reserves from AIG’s Life and Retirement Run-Off Lines and approximately $ 4.1 billion of reserves from AIG’s General Insurance Run-Off Lines, related to business written by multiple wholly-owned AIG subsidiaries, had been ceded to Fortitude Re under these reinsurance transactions. As of closing of the Majority Interest Fortitude Sale, these reinsurance transactions are no longer considered affiliated transactions and Fortitude Re is the reinsurer of the majority of AIG’s Run-Off operations. These reinsurance transactions between AIG and Fortitude Re were 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 other comprehensive income). As a result of the deconsolidation resulting from the Majority Interest Fortitude Sale, 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 capital 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. There is a diverse pool of assets supporting the funds withheld arrangements with Fortitude Re. The following summarizes the composition of the pool of assets as of December 31, 2020: December 31, 2020 Carrying Fair (in millions) Value Value Corresponding Accounting Policy Fixed maturity securities - available for sale (a) $ 36,047 $ 36,047 Fair value through other comprehensive income Fixed maturity securities - fair value option 200 200 Fair value through net investment income Commercial mortgage loans 3,679 4,010 Amortized cost Real estate investments 358 585 Amortized cost Private equity funds / hedge funds 1,168 1,168 Fair value through net investment income Policy loans 413 413 Amortized cost Short-term Investments 34 34 Fair value through net investment income Funds withheld investment assets 41,899 42,457 Derivative assets, net (b) ( 1) ( 1) Fair value through realized capital gains (losses) Other (c) 604 604 Amortized cost Total $ 42,502 $ 43,060 (a) The change in the net unrealized gains (losses) on available for sale securities related to the Fortitude Re funds withheld assets was $ 1.0 billion ($ 812 million after-tax) during the post deconsolidation period (June 2, 2020-December 31, 2020). (b) The derivative assets have been presented net of collateral. The derivative assets supporting the Fortitude Re funds withheld arrangements had a fair market value of $ 357 million as of December 31, 2020. These derivative assets are fully collateralized. (c) Primarily comprised of Cash and Accrued investment income. The impact of the funds withheld arrangements with Fortitude Re for the period post June 2, 2020 deconsolidation was as follows: Twelve Months Ended (in millions) December 31, 2020 Net underwriting income $ - Net investment income - Fortitude Re funds withheld assets 1,053 Net realized capital losses on Fortitude Re funds withheld assets: Net realized capital gains - Fortitude Re funds withheld assets 463 Net realized capital losses - Fortitude Re embedded derivatives ( 2,645) Net realized capital losses on Fortitude Re funds withheld assets ( 2,182) Loss from continuing operations before income tax benefit ( 1,129) Income tax benefit (a) ( 237) Net loss ( 892) Change in unrealized appreciation of all other investments (a) 812 Comprehensive loss $ ( 80) (a) The income tax expense (benefit) and the tax impact in accumulated other comprehensive income was computed using AIG’s U.S. statutory tax rate of 21 percent. Various assets supporting the Fortitude Re funds withheld arrangements are reported at amortized cost, and as such, changes in the fair value of these assets are not reflected in the financial statements. However, changes in the fair value of these assets are included in the embedded derivative in the Fortitude Re funds withheld arrangement and the appreciation of these assets is the primary driver of the comprehensive loss reflected above. Reinsurance Security Our third-party reinsurance arrangements do not relieve us from our direct obligations to our beneficiaries. Thus, a credit exposure exists with respect to both short-duration and long-duration reinsurance ceded to the extent that any reinsurer fails to meet the obligations assumed under any reinsurance agreement. We hold substantial collateral as security under related reinsurance agreements in the form of funds, securities, and/or letters of credit. A provision has been recorded for estimated unrecoverable reinsurance. In light of collateral held, we believe that no exposure to a single reinsurer represents an inappropriate concentration of credit risk to AIG. Gross reinsurance assets due from reinsurers exceeding 5 percent of our total reinsurance assets were approximately $ 54.0 billion and $ 19.0 billion at December 31, 2020 and 2019, respectively, of which approximately $ 2.6 billion and $ 2.8 billion at December 31, 2020 and 2019, respectively, was not secured by collateral. Reinsurance – Credit Losses The estimation of reinsurance recoverables involves a significant amount of judgment, particularly for latent exposures, such as asbestos, due to their long-tail nature. Reinsurance assets include reinsurance recoverables on unpaid losses and loss adjustment expenses that are estimated as part of our loss reserving process and, consequently, are subject to similar judgments and uncertainties as the estimation of gross loss reserves. Similarly, Other assets include reinsurance recoverables for contracts which are accounted for as deposits. 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 uncollectable reinsurance that reduces the carrying amount of reinsurance and other assets on the consolidated balance sheets (collectively, the reinsurance recoverable balances). 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 determined by the Obligor Risk Ratings (ORRs) we assign to each reinsurer based upon our financial reviews; insurers 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 rating. The allowance for credit losses excludes disputed amounts. An allowance for disputes is established for a reinsurance recoverable using the losses incurred model for contingencies. The total reinsurance recoverables as of December 31, 2020 were $ 75.8 billion. As of that date, utilizing AIG’s ORRs, (i) approximately 92 percent of the reinsurance recoverables were investment grade, of which 52 percent related to General Insurance and 40 percent related to Life and Retirement; (ii) approximately 7 percent of the reinsurance recoverables were non-investment grade, the majority of which related to General Insurance; (iii) less than one one As of December 31, 2020, approximately 64 percent of our non-investment grade reinsurance exposure related to captive insurers. These arrangements are typically collateralized by letters of credit, funds withheld or trust agreements. Reinsurance Recoverable Allowance The following table presents a rollforward of the reinsurance recoverable allowance: Year Ended December 31, 2020 General Life and (in millions) Insurance Retirement Total Balance, beginning of period $ 111 $ 40 $ 151 Initial allowance upon CECL adoption 202 22 224 Current period provision for expected credit losses and disputes ( 12) 21 9 Write-offs charged against the allowance for credit losses and disputes ( 9) - ( 9) Balance, end of year $ 292 $ 83 $ 375 There were no material recoveries of credit losses previously written off for the year ended December 31, 2020. Past-Due Status We consider a reinsurance asset to be past due when it is 90 days past due. The allowance for credit losses is estimated excluding disputed amounts. An allowance for disputes is established using the losses incurred method for contingencies. Past due balances on claims that are not in dispute were not material for any of the periods presented.

DEFERRED POLICY ACQUISITION COS

DEFERRED POLICY ACQUISITION COSTS	12 Months Ended

DEFERRED POLICY ACQUISITION COSTS
DEFERRED POLICY ACQUISITION COSTS	9. Deferred Policy Acquisition Costs Deferred policy acquisition costs (DAC) represent those costs that are incremental and directly related to the successful acquisition of new or renewal of existing insurance contracts. We defer incremental costs that result directly from, and are essential to, the acquisition or renewal of an insurance contract. Such deferred policy acquisition costs 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. 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. Short-duration insurance contracts: 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. Long-duration insurance contracts: Policy acquisition costs for participating life, traditional life and accident and health insurance products are generally deferred and amortized, with interest, over the premium paying period. The assumptions used to calculate the benefit liabilities and DAC for these traditional products are set when a policy is issued and do not change with changes in actual experience, unless a loss recognition event occurs. These “locked-in” assumptions include mortality, morbidity, persistency, maintenance expenses and investment returns, and include margins for adverse deviation to reflect uncertainty given that actual experience might deviate from these assumptions. A loss recognition event occurs when there is a shortfall between the carrying amount of future policy benefit liabilities, net of DAC, and what the future policy benefit liabilities, net of DAC, would be when applying updated current assumptions. When we determine a loss recognition event has occurred, we first reduce any DAC related to that block of business through amortization of acquisition expense, and after DAC is depleted, we record additional liabilities through a charge to Policyholder benefits and losses incurred. Groupings for loss recognition testing are consistent with our manner of acquiring, servicing and measuring the profitability of the business and applied by product groupings. We perform separate loss recognition tests for traditional life products, payout annuities and long-term care products. Once loss recognition has been recorded for a block of business, the old assumption set is replaced and the assumption set used for the loss recognition would then be subject to the lock-in principle. Investment-oriented contracts: Certain policy acquisition costs and policy issuance costs related to universal life and investment-type products (collectively, investment-oriented products) are deferred and amortized, with interest, in relation to the incidence of estimated gross profits to be realized over the estimated lives of the contracts. DAC on investment-oriented contracts were approximately $ 5.1 billion and $ 6.1 billion at December 31, 2020 and 2019, respectively. Estimated gross profits are affected by a number of factors, including levels of current and expected interest rates, net investment income and spreads, net realized capital gains and losses, fees, surrender rates, mortality experience, policyholder behavior experience and equity market returns and volatility. In each reporting period, current period amortization expense is adjusted to reflect actual gross profits. If the assumptions used for estimating gross profit change significantly, DAC is recalculated using the new assumptions, including actuarial assumptions such as mortality, lapse, benefit utilization, and premium persistency, and any resulting adjustment is included in income. If the new assumptions indicate that future estimated gross profits are higher than previously estimated, DAC will be increased resulting in a decrease in amortization expense and increase in income in the current period; if future estimated gross profits are lower than previously estimated, DAC will be decreased resulting in an increase in amortization expense and decrease in income in the current period. Updating such assumptions may result in acceleration of amortization in some products and deceleration of amortization in other products. 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 current and projected future profitability of the underlying insurance contracts. To estimate future estimated gross profits for variable annuity products, a long-term annual asset growth assumption is applied to determine the future growth in assets and related asset-based fees. In determining the asset growth rate, the effect of short-term fluctuations in the equity markets is partially mitigated through the use of a “reversion to the mean” methodology whereby short-term asset growth above or below long-term annual rate assumptions impacts the growth assumption applied to the five-year period subsequent to the current balance sheet date. The reversion to the mean methodology allows us to maintain our long-term growth assumptions, while also giving consideration to the effect of actual investment performance. When actual performance significantly deviates from the annual long-term growth assumption, as evidenced by growth assumptions in the five-year reversion to the mean period falling below a certain rate (floor) or rising above a certain rate (cap) for a sustained period, judgment may be applied to revise or “unlock” the growth rate assumptions to be used for both the five-year reversion to the mean period as well as the long-term annual growth assumption applied to subsequent periods. Shadow DAC and Shadow Loss Recognition: DAC related to investment-oriented products is also adjusted to reflect the effect of unrealized gains or losses on fixed maturity securities available for sale, with related changes recognized through Other comprehensive income (shadow DAC). The adjustment is made at each balance sheet date, as if the securities had been sold at their stated aggregate fair value and the proceeds reinvested at current yields. Similarly, for long-duration traditional insurance contracts, if the assets supporting the liabilities are in a net unrealized gain position at the balance sheet date, loss recognition testing assumptions are updated to exclude such gains from future cash flows by reflecting the impact of reinvestment rates on future yields. If a future loss is anticipated under this basis, any additional shortfall indicated by loss recognition tests is recognized as a reduction in accumulated other comprehensive income (shadow loss recognition). Similar to other loss recognition on long-duration insurance contracts, such shortfall is first reflected as a reduction in DAC and secondly as an increase in liabilities for future policy benefits. The change in these adjustments, net of tax, is included with the change in net unrealized appreciation of investments that is credited or charged directly to Other comprehensive income. Internal Replacements of Long-duration and Investment-oriented Products: For some products, policyholders can elect to modify product benefits, features, rights or coverages by exchanging a contract for a new contract or by amendment, endorsement, or rider to a contract, or by the election of a feature or coverage within a contract. These transactions are known as internal replacements. If the modification does not substantially change the contract, we do not change the accounting and amortization of existing DAC and related actuarial balances. If an internal replacement represents a substantial change, the original contract is considered to be extinguished and any related DAC or other policy balances are charged or credited to income, and any new deferrable costs associated with the replacement contract are deferred. Value of Business Acquired (VOBA) is determined at the time of acquisition and is reported in the Consolidated Balance Sheets with DAC. This value is based on the present value of future pre-tax profits discounted at yields applicable at the time of purchase. For participating life, traditional life and accident and health insurance products, VOBA is amortized over the life of the business in a manner similar to that for DAC based on the assumptions at purchase. For investment-oriented products, VOBA is amortized in relation to estimated gross profits and adjusted for the effect of unrealized gains or losses on fixed maturity securities available for sale and prior to 2018, equity securities at fair value in a manner similar to DAC. The following table presents a rollforward of DAC and VOBA: Years Ended December 31, (in millions) 2020 2019 2018 Balance, beginning of year $ 11,207 $ 12,694 $ 10,994 Acquisitions - - 298 Dispositions ( 467) - - Acquisition costs deferred 4,292 5,403 5,832 Amortization expense ( 4,211) ( 5,164) ( 5,386) Change related to unrealized appreciation (depreciation) of investments ( 1,096) ( 1,768) 1,063 Other, including foreign exchange 80 42 ( 107) Balance, end of year (a) $ 9,805 $ 11,207 $ 12,694 Supplemental Information: VOBA amortization expense included in DAC amortization (b) $ 192 $ 171 $ 243 VOBA, end of year included in DAC balance (c) 126 317 438 (a) Net of reductions in DAC of $ 1.0 billion, $ 1.8 billion and $ 1.0 billion at December 31, 2020, 2019 and 2018, respectively, related to shadow DAC. (b) In connection with the Majority Interest Fortitude Sale, and the subsequent deconsolidation of Fortitude Re, AIG wrote off $ 169 million of VOBA. (c) Includes $ 101 million of VOBA from the acquisition of Validus in 2018, the majority of which was amortized in 2019 with the remainder fully amortized in 2020. The percentage of the unamortized balance of VOBA at December 31, 2020 expected to be amortized in 2021 through 2025 by year is: 11.2 percent, 10.4 percent, 10.4 percent, 8.8 percent and 8.8 percent, respectively, with 50.4 percent being amortized after five years. These projections are based on current estimates for investment income and spreads, persistency, mortality and morbidity assumptions. DAC, VOBA and SIA for insurance-oriented and investment-oriented products are reviewed for recoverability, which involves estimating the future profitability of current business. This review involves significant management judgment. If actual profitability is substantially lower than estimated, AIG’s DAC, VOBA and SIA may be subject to an impairment charge and AIG’s results of operations could be significantly affected in the period the impairment charge is recognized and in future periods. VOBA is reported with the DAC balance and SIAs are included in Other assets.

VARIABLE INTEREST ENTITIES
VARIABLE INTEREST ENTITIES	10. Variable Interest Entities A variable interest entity (VIE) is a legal entity that does not have sufficient equity at risk to finance its activities without additional subordinated financial support or is structured such that equity investors lack the ability to make significant decisions relating to the entity’s operations through voting rights or do not substantively participate in the gains and losses of the entity. Consolidation of a VIE by its primary beneficiary is not based on majority voting interest, but is based on other criteria discussed below. We enter into various arrangements with VIEs in the normal course of business and consolidate the VIEs when we determine we are the primary beneficiary. This analysis includes a review of the VIE’s capital structure, related contractual relationships and terms, nature of the VIE’s operations and purpose, nature of the VIE’s interests issued and our involvement with the entity. When assessing the need to consolidate a VIE, we evaluate the design of the VIE as well as the related risks to which the entity was designed to expose the variable interest holders. The primary beneficiary is the entity that has both (i) the power to direct the activities of the VIE that most significantly affect the entity’s economic performance and (ii) the obligation to absorb losses or the right to receive benefits that could be potentially significant to the VIE. While also considering these factors, the consolidation conclusion depends on the breadth of our decision-making ability and our ability to influence activities that significantly affect the economic performance of the VIE. Balance Sheet Classification and Exposure to Loss Creditors or beneficial interest holders of VIEs for which the Company is the primary beneficiary generally have recourse only to the assets and cash flows of the VIEs and do not have recourse to the Company, except in limited circumstances when the Company has provided a guarantee to the VIE’s interest holders. The following table presents the total assets and total liabilities associated with our variable interests in consolidated VIEs, as classified in the Consolidated Balance Sheets: Real Estate and Affordable Investment Securitization Housing (in millions) Entities (d) Vehicles (e) Partnerships Other Total December 31, 2020 Assets: Bonds available for sale $ - $ 6,089 $ - $ - $ 6,089 Other bond securities - 2,367 - - 2,367 Equity securities 507 - - - 507 Mortgage and other loans receivable - 3,135 - - 3,135 Other invested assets Alternative investments (a) 2,689 - - - 2,689 Investment Real Estate 3,378 - 3,558 - 6,936 Short-term investments 365 1,534 - 27 1,926 Accrued investment income - 38 - - 38 Cash 129 - 203 - 332 Other assets 166 120 243 - 529 Other 3 - - 2 5 Total assets (b) $ 7,237 $ 13,283 $ 4,004 $ 29 $ 24,553 Liabilities: Debt of consolidated investment entities $ 2,559 $ 3,961 $ 2,287 $ 2 $ 8,809 Other (c) 180 187 187 10 564 Total liabilities $ 2,739 $ 4,148 $ 2,474 $ 12 $ 9,373 December 31, 2019 Assets: Bonds available for sale $ - $ 7,416 $ - $ - $ 7,416 Other bond securities - 3,324 - 1 3,325 Mortgage and other loans receivable - 3,860 - - 3,860 Other invested assets Alternative investments (a) 1,436 - - 17 1,453 Investment Real Estate 3,795 - 3,464 25 7,284 Short-term investments 315 1,861 - 26 2,202 Accrued investment income - 83 - 83 Cash 132 - 234 7 373 Other assets 161 56 235 2 454 Other 3 - - 7 10 Total assets (b) $ 5,842 $ 16,600 $ 3,933 $ 85 $ 26,460 Liabilities: Debt of consolidated investment entities $ 2,691 $ 4,475 $ 2,074 $ 4 $ 9,244 Other (c) 216 379 195 24 814 Total liabilities $ 2,907 $ 4,854 $ 2,269 $ 28 $ 10,058 (a) Comprised primarily of investments in real estate joint ventures at December 31, 2020 and 2019. (b) The assets of each VIE can be used only to settle specific obligations of that VIE. (c) Comprised primarily of Other liabilities at December 31, 2020 and 2019. (d) At December 31, 2020 and 2019, off-balance sheet exposure primarily consisting of commitments to real estate and investment entities was $ 1.8 billion and $ 2.6 billion, respectively. (e) At December 31, 2020 and 2019, the company had contributed total assets of $ 12.5 billion and $ 15.6 billion, respectively, into consolidated securitization vehicles. We calculate our maximum exposure to loss to be (i) the amount invested in the debt or equity of the VIE, (ii) the notional amount of VIE assets or liabilities where we have also provided credit protection to the VIE with the VIE as the referenced obligation, and (iii) other commitments and guarantees to the VIE. Under the terms of six transactions entered into between 2012 and 2014 securitizing portfolios of certain debt securities previously owned by AIG and its affiliates, an indirectly wholly-owned subsidiary of AIG is obligated to make certain capital contributions to such a securitization VIE in the event that the VIE is unable to redeem any rated notes it has in issue on the relevant redemption date. AIG has provided a guarantee to the six securitization VIEs of the obligations of its indirectly wholly-owned subsidiary to make such capital contributions when due. At December 31, 2020, in aggregate, $ 175 million of rated notes issued by such VIEs were outstanding and held by investors other than AIG and its consolidated affiliates. SunAmerica Affordable Housing Partners, Inc. (SAAHP) provides a Base Internal Rate of Return (IRR) guarantee to its third party investors, so that on a specified date if the Investor has not received distributions of cash and allocations of certain tax benefits required to achieve their Base IRR as provided for in the Partnership Agreement, SAAHP shall distribute cash to effectively generate the Base IRR to the investor. In addition, SAAHP has from time to time guaranteed certain debt issued by third parties related to its business activities. As of December 31, 2020, the off balance sheet amount of that guarantee was approximately $4 million. The following table presents total assets of unconsolidated VIEs in which we hold a variable interest, as well as our maximum exposure to loss associated with these VIEs: Maximum Exposure to Loss Total VIE On-Balance Off-Balance (in millions) Assets Sheet (b) Sheet Total December 31, 2020 Real estate and investment entities (a) $ 321,716 $ 6,420 $ 3,273 (c) $ 9,693 Affordable housing partnerships 2,801 368 4 372 Other 1,733 195 546 (d) 741 Total $ 326,250 $ 6,983 $ 3,823 $ 10,806 December 31, 2019 Real estate and investment entities (a) $ 283,349 $ 6,519 $ 3,286 (c) $ 9,805 Affordable housing partnerships 3,351 453 - 453 Other 5,320 310 561 (d) 871 Total $ 292,020 $ 7,282 $ 3,847 $ 11,129 (a) Comprised primarily of hedge funds and private equity funds. (b) At December 31, 2020 and 2019, $ 6.8 billion and $ 7.0 billion, respectively, of our total unconsolidated VIE assets were recorded as Other invested assets. (c) These amounts represent our unfunded commitments to invest in private equity funds and hedge funds. (d) These amounts represent our estimate of the maximum exposure to loss under certain insurance policies issued to VIEs if a hypothetical loss occurred to the extent of the full amount of the insured value. Our insurance policies cover defined risks and our estimate of liability is included in our insurance reserves on the balance sheet. Real Estate and Investment Entities Through our insurance operations and AIG Global Real Estate Investment Corp., we are an investor in various real estate investment entities, some of which are VIEs. These investments are typically with unaffiliated third-party developers via a partnership or limited liability company structure. The VIEs’ activities consist of the development or redevelopment of commercial, industrial and residential real estate. Our involvement varies from being a passive equity investor or finance provider to actively managing the activities of the VIEs. Our insurance operations participate as passive investors in the equity issued by certain third-party-managed hedge and private equity funds that are VIEs. Our insurance operations typically are not involved in the design or establishment of these VIEs, nor do they actively participate in the management of the VIEs. Securitization Vehicles We created certain VIEs that hold investments, primarily in investment-grade debt securities and loans, and issued beneficial interests in these investments. Some of these VIEs were created to facilitate our purchase of asset-backed securities. In these situations, all of the beneficial interests are owned by our insurance operations and are consolidated by AIG. In other instances, we have created VIEs that are securitizations of residential mortgage loans or other forms of collateralized loan obligations. Our insurance subsidiaries own some of the beneficial interests, and we maintain the power to direct the activities of the VIEs that most significantly impact their economic performance. Accordingly, we consolidate these entities and those beneficial interests issued to third parties are reported as debt of consolidated investment entities. This debt is non-recourse to AIG. Affordable Housing Partnerships SAAHP organized and invested in limited partnerships that develop and operate affordable housing qualifying for federal, state, and historic tax credits, in addition to a few market rate properties across the United States. The operating partnerships are VIEs, whose debt is generally non-recourse in nature, and the general partners of which are mostly unaffiliated third-party developers. We account for our investments in operating partnerships using the equity method of accounting, unless they are required to be consolidated. We consolidate an operating partnership if the general partner is an affiliated entity or we otherwise have the power to direct activities that most significantly impact the entities’ economic performance. The pre-tax income of SAAHP is reported as a component of the Life and Retirement segment. RMBS, CMBS, Other ABS and CDOs Primarily through our insurance operations, we are a passive investor in RMBS, CMBS, other ABS and CDOs, the majority of which are issued by domestic special purpose entities. We generally do not sponsor or transfer assets to, or act as the servicer to these asset-backed structures, and were not involved in the design of these entities. Our maximum exposure in these types of structures is limited to our investment in securities issued by these entities. Based on the nature of our investments and our passive involvement in these types of structures, we have determined that we are not the primary beneficiary of these entities. We have not included these entities in the above tables; however, the fair values of our investments in these structures are reported in Notes 5 and 6 herein.

DERIVATIVES AND HEDGE ACCOUNTING
DERIVATIVES AND HEDGE ACCOUNTING	11. Derivatives and Hedge Accounting We use derivatives and other financial instruments as part of our financial risk management programs and as part of our investment operations. Interest rate derivatives (such as interest rate swaps) are used to manage interest rate risk associated with embedded derivatives contained in insurance contract liabilities, fixed maturity securities, outstanding medium- and long-term notes as well as other interest rate sensitive assets and liabilities. Foreign exchange derivatives (principally foreign exchange forwards and swaps) are used to economically mitigate risk associated with non-U.S. dollar denominated debt, net capital exposures, foreign currency transactions, and foreign denominated investments. Equity derivatives are used to mitigate financial risk embedded in certain insurance liabilities and economically hedge certain investments. 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 instruments 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. Interest rate, currency, equity and commodity swaps, credit contracts, swaptions, options and forward transactions are accounted for as derivatives, recorded on a trade-date basis and carried at fair value. Unrealized gains and losses are reflected in income, when appropriate. Aggregate asset or liability positions are netted on the Consolidated Balance Sheets only to the extent permitted by qualifying master netting arrangements in place with each respective counterparty. Cash collateral posted with counterparties in conjunction with transactions supported by qualifying master netting arrangements is reported as a reduction of the corresponding net derivative liability, while cash collateral received in conjunction with transactions supported by qualifying master netting arrangements is reported as a reduction of the corresponding net derivative asset. Derivatives, with the exception of embedded derivatives, are reported at fair value in the Consolidated Balance Sheets in Other assets and Other liabilities. Embedded derivatives are generally presented with the host contract in the Consolidated Balance Sheets. A bifurcated embedded derivative is measured at fair value and accounted for in the same manner as a free standing derivative contract. The corresponding host contract is accounted for according to the accounting guidance applicable for that instrument. For additional information on embedded derivatives see Notes 5 and 14. The following table presents the notional amounts of our derivatives and the fair value of derivative assets and liabilities in the Consolidated Balance Sheets: December 31, 2020 December 31, 2019 Gross Derivative Assets Gross Derivative Liabilities Gross Derivative Assets Gross Derivative Liabilities Notional Fair Notional Fair Notional Fair Notional Fair (in millions) Amount Value Amount Value Amount Value Amount Value Derivatives designated as hedging instruments: (a) Interest rate contracts $ 815 $ 16 $ 356 $ 11 $ 495 $ 3 $ 410 $ 7 Foreign exchange contracts 3,468 256 7,424 379 4,328 342 5,230 162 Derivatives not designated as hedging instruments: (a) Interest rate contracts 62,259 4,621 48,732 4,425 52,437 3,197 35,231 2,742 Foreign exchange contracts 9,518 766 12,860 711 8,133 698 12,093 863 Equity contracts 22,924 1,130 7,076 223 18,533 769 7,539 139 Credit contracts (b) 5,797 2 969 67 8,457 3 923 89 Other contracts (c) 43,441 14 54 6 40,582 14 56 7 Total derivatives, gross $ 148,222 $ 6,805 $ 77,471 $ 5,822 $ 132,965 $ 5,026 $ 61,482 $ 4,009 Counterparty netting (d) ( 3,812) ( 3,812) ( 2,427) ( 2,427) Cash collateral (e) ( 2,219) ( 1,441) ( 1,806) ( 527) Total derivatives on consolidated balance sheets (f) $ 774 $ 569 $ 793 $ 1,055 (a) Fair value amounts are shown before the effects of counterparty netting adjustments and offsetting cash collateral. (b) As of December 31, 2020 and 2019, included CDSs on super senior multi-sector CDOs with a net notional amount of $ 137 million and $ 152 million (fair value liability of $ 44 million and $ 48 million), respectively. The net notional amount represents the maximum exposure to loss on the portfolio. (c) Consists primarily of stable value wraps and contracts with multiple underlying exposures. (d) Represents netting of derivative exposures covered by a qualifying master netting agreement. (e) Represents cash collateral posted and received that is eligible for netting. (f) Freestanding derivatives only, excludes embedded derivatives. Derivative instrument assets and liabilities are recorded in Other assets and Other liabilities, respectively. Fair value of assets related to bifurcated embedded derivatives was zero at both December 31, 2020 and December 31, 2019. Fair value of liabilities related to bifurcated embedded derivatives was $ 15.8 billion and $ 6.9 billion, respectively, at December 31, 2020 and December 31, 2019. A bifurcated embedded derivative is generally presented with the host contract in the Consolidated Balance Sheets. Embedded derivatives are primarily related to guarantee features in variable annuity products, which include equity and interest rate components, and the funds withheld arrangement with Fortitude Re. For additional information see Note 8 to the Consolidated Financial Statements . Collateral We engage in derivative transactions that are not subject to a clearing requirement directly with unaffiliated third parties, in most cases, under International Swaps and Derivatives Association, Inc. (ISDA) Master Agreements. Many of the ISDA Master Agreements also include Credit Support Annex provisions, which provide for collateral postings that may vary at various ratings and threshold levels. We attempt to reduce our risk with certain counterparties by entering into agreements that enable collateral to be obtained from a counterparty on an upfront or contingent basis. We minimize the risk that counterparties might be unable to fulfill their contractual obligations by monitoring counterparty credit exposure and collateral value and generally requiring additional collateral to be posted upon the occurrence of certain events or circumstances. In addition, certain derivative transactions have provisions that require collateral to be posted upon a downgrade of our long-term debt ratings or give the counterparty the right to terminate the transaction. In the case of some of the derivative transactions, upon a downgrade of our long-term debt ratings, as an alternative to posting collateral and subject to certain conditions, we may assign the transaction to an obligor with higher debt ratings or arrange for a substitute guarantee of our obligations by an obligor with higher debt ratings or take other similar action. The actual amount of collateral required to be posted to counterparties in the event of such downgrades, or the aggregate amount of payments that we could be required to make, depends on market conditions, the fair value of outstanding affected transactions and other factors prevailing at and after the time of the downgrade. Collateral posted by us to third parties for derivative transactions was $ 3.0 billion and $ 2.2 billion at December 31, 2020 and 2019, respectively. In the case of collateral posted under derivative transactions that are not subject to clearing, this collateral can generally be repledged or resold by the counterparties. Collateral provided to us from third parties for derivative transactions was $ 2.3 billion and $ 2.2 billion at December 31, 2020 and 2019, respectively. In the case of collateral provided to us under derivative transactions that are not subject to clearing, we generally can repledge or resell collateral. Offsetting We have elected to present all derivative receivables and derivative payables, and the related cash collateral received and paid, on a net basis on our Consolidated Balance Sheets when a legally enforceable ISDA Master Agreement exists between us and our derivative counterparty. An ISDA Master Agreement is an agreement governing multiple derivative transactions between two counterparties. The ISDA Master Agreement generally provides for the net settlement of all, or a specified group, of these derivative transactions, as well as transferred collateral, through a single payment, and in a single currency, as applicable. The net settlement provisions apply in the event of a default on, or affecting any, one derivative transaction or a termination event affecting all, or a specified group of, derivative transactions governed by the ISDA Master Agreement. Hedge Accounting We designated certain derivatives entered into with third parties as fair value hedges of available for sale investment securities held by our insurance subsidiaries. The fair value hedges include foreign currency forwards and cross currency swaps designated as hedges of the change in fair value of foreign currency denominated available for sale securities attributable to changes in foreign exchange rates. We also designated certain interest rate swaps entered into with third parties as fair value hedges of fixed rate GICs attributable to changes in benchmark interest 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, 2020, 2019 and 2018, we recognized gains (losses) of $( 128) million, $ 116 million and $ 34 million, respectively, included in Change in foreign currency translation adjustment in Other comprehensive income related to the net investment hedge relationships. A qualitative methodology is utilized to assess hedge effectiveness for net investment hedges, while regression analysis is employed for all other hedges.

Derivatives Not Designated as Hedging Instruments The following table presents the effect of derivative instruments not designated as hedging instruments in the Consolidated Statements of Income: Years Ended December 31, Gains (Losses) Recognized in Earnings (in millions) 2020 2019 2018 By Derivative Type: Interest rate contracts $ 1,451 $ 1,319 $ ( 509) Foreign exchange contracts ( 389) ( 25) 543 Equity contracts 211 ( 316) ( 56) Credit contracts 52 61 32 Other contracts 61 64 65 Embedded derivatives ( 4,722) ( 1,464) 629 Total $ ( 3,336) $ ( 361) $ 704 By Classification: Policy fees $ 62 $ 68 $ 67 Net investment income ( 8) ( 125) ( 3) Net realized capital gains (losses) - excluding Fortitude Re funds withheld assets ( 508) ( 316) 642 Net realized capital gains (losses) on Fortitude Re funds withheld assets ( 2,894) - - Policyholder benefits and claims incurred 12 12 ( 2) Total $ ( 3,336) $ ( 361) $ 704 Credit Risk-Related Contingent Features We estimate that at December 31, 2020, based on our outstanding financial derivative transactions, a downgrade of our long-term senior debt ratings to BBB or BBB– by Standard & Poor’s Financial Services LLC, a subsidiary of S&P Global Inc., and/or a downgrade to Baa2 or Baa3 by Moody’s Investors’ Service, Inc. would permit counterparties to make additional collateral calls and permit certain counterparties to elect early termination of contracts, resulting in corresponding collateral postings and termination payments in the total amount of up to approximately $ 47 million. The aggregate fair value of our derivatives that were in a net liability position and that contain such credit risk-related contingencies which can be triggered below our long-term senior debt ratings of BBB+ or Baa1 was approximately $ 257 million and $ 336 million at December 31, 2020 and 2019, respectively. The aggregate fair value of assets posted as collateral under these contracts at December 31, 2020 and 2019, was approximately $ 306 million and $ 381 million, respectively. Hybrid Securities with Embedded Credit Derivatives We invest in hybrid securities (such as credit-linked notes) with the intent of generating income, and not specifically to acquire exposure to embedded derivative risk. As is the case with our other investments in RMBS, CMBS, CDOs and ABS, our investments in these hybrid securities are exposed to losses only up to the amount of our initial investment in the hybrid security. Other than our initial investment in the hybrid securities, we have no further obligation to make payments on the embedded credit derivatives in the related hybrid securities. We elect to account for our investments in these hybrid securities with embedded written credit derivatives at fair value, with changes in fair value recognized in Net investment income and Other income. Our investments in these hybrid securities are reported as Other bond securities in the Consolidated Balance Sheets. The fair values of these hybrid securities were $ 2.4 billion and $ 3.3 billion at December 31, 2020 and 2019, respectively. These securities have par amounts of $ 5.0 billion and $ 7.4 billion at December 31, 2020 and 2019, respectively, and have remaining stated maturity dates that extend to 2052.

GOODWILL AND OTHER INTANGIBLE ASSETS
GOODWILL AND OTHER INTANGIBLE ASSETS	12. Goodwill and Other Intangible Assets Goodwill represents the future economic benefits arising from assets acquired in a business combination that are not individually identified and separately recognized. Goodwill is tested for impairment annually or more frequently if circumstances indicate an impairment may have occurred. At December 31, 2020, as a result of the 2020 segment changes, goodwill is reported within our General Insurance business – North America and International operating segments, our Life and Retirement business – Life Insurance operating segment and our Other Operations segment. When a business is transferred from one reporting unit to another, as occurred as part of the 2020 segment changes, goodwill from the original operating segment 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 an operating segment 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 an operating segment 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 operating segment and compare the estimated fair value with the carrying amount of the operating segment, including allocated goodwill. The estimate of an operating segment’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 an operating segment to be used in the impairment test. If the estimated fair value of an operating segment exceeds its carrying amount, goodwill is not impaired. If the carrying value of an operating segment exceeds its estimated fair value, goodwill associated with that operating segment 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 earnings. The date of our annual goodwill Impairment testing is July 1. We performed our annual goodwill impairment tests of all reporting units and reassessed goodwill as a result of the aforementioned segment change using a combination of both qualitative and quantitative assessments and concluded that our goodwill was not impaired. The following table presents the changes in goodwill by operating segment: General Insurance North Life Other (in millions) America International Insurance Operations Total Balance at January 1, 2018: Goodwill - gross $ 1,473 $ 3,269 $ 270 $ 59 $ 5,071 Accumulated impairments ( 1,145) ( 2,255) ( 67) ( 10) ( 3,477) Net goodwill 328 1,014 203 49 1,594 Increase (decrease) due to: Acquisitions (a) 2,332 157 46 9 2,544 Other ( 12) ( 48) ( 5) 9 ( 56) Balance at December 31, 2018: Goodwill - gross 3,793 3,378 311 77 7,559 Accumulated impairments ( 1,145) ( 2,255) ( 67) ( 10) ( 3,477) Net goodwill 2,648 1,123 244 67 4,082 Increase (decrease) due to: Acquisitions - 20 - - 20 Other (b) - 26 ( 77) ( 13) ( 64) Balance at December 31, 2019: Goodwill - gross 3,793 3,424 234 64 7,515 Accumulated impairments ( 1,145) ( 2,255) ( 67) ( 10) ( 3,477) Net goodwill 2,648 1,169 167 54 4,038 Increase (decrease) due to: Dispositions ( 2) - - ( 4) ( 6) Other - 32 10 - 42 Balance at December 31, 2020: Goodwill - gross 3,791 3,456 244 60 7,551 Accumulated impairments ( 1,145) ( 2,255) ( 67) ( 10) ( 3,477) Net goodwill $ 2,646 $ 1,201 $ 177 $ 50 $ 4,074 (a) Includes goodwill of $ 2.0 billion, $ 492 million and $ 46 million relating to the acquisitions of Validus, Glatfelter and Ellipse, respectively. (b) Reflects $ 98 million of goodwill that has been reclassified to assets held for sale. 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 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. The Other intangible assets and VODA resulted primarily from the acquisition of Validus. The following table presents the changes in other intangible assets and the VODA by operating segment: General Insurance North Life Other (in millions) America International Insurance Operations Total Other intangible assets Balance at January 1, 2018 $ 27 $ 8 $ 34 $ 37 $ 106 Increase (decrease) due to: Acquisitions 61 207 16 - 284 Amortization ( 2) ( 3) ( 4) ( 2) ( 11) Other - - - ( 19) ( 19) Balance at December 31, 2018 $ 86 $ 212 $ 46 $ 16 $ 360 Increase (decrease) due to: Acquisitions - - - - - Amortization ( 1) ( 1) ( 4) ( 2) ( 8) Other ( 3) - ( 18) 2 ( 19) Balance at December 31, 2019 $ 82 $ 211 $ 24 $ 16 $ 333 Increase (decrease) due to: Acquisitions - - - - - Dispositions - - - ( 4) ( 4) Amortization ( 2) ( 1) ( 4) ( 2) ( 9) Other ( 1) - 2 ( 2) ( 1) Balance at December 31, 2020 $ 79 $ 210 $ 22 $ 8 $ 319 Value of distribution network acquired Balance at January 1, 2018 $ - $ - $ - $ - $ - Increase (decrease) due to: Acquisitions - - - 582 582 Amortization - - - ( 15) ( 15) Other - - - 2 2 Balance at December 31, 2018 $ - $ - $ - $ 569 $ 569 Increase (decrease) due to: Acquisitions - - - - - Amortization - - - ( 39) ( 39) Other - - - 6 6 Balance at December 31, 2019 $ - $ - $ - $ 536 $ 536 Increase (decrease) due to: Acquisitions - - - - - Amortization - - - ( 40) ( 40) Other - - - 1 1 Balance at December 31, 2020 $ - $ - $ - $ 497 $ 497 The percentage of the unamortized balance of Other intangible assets and VODA at December 31, 2020 expected to be amortized in 2021 through 2025 by year is 9.2 percent, 9.3 percent, 9.5 percent, 8.4 percent and 8.2 percent, respectively, with 55.4 percent being amortized after five years.

Insurance Liabilites
INSURANCE LIABILITIES	13. Insurance Liabilities Liability for Unpaid Losses and Loss Adjustment Expenses (Loss Reserves) Loss reserves represent the accumulation of estimates of unpaid claims, including estimates for claims incurred but not reported and loss adjustment expenses, less applicable discount. We regularly review and update the methods used to determine loss reserve estimates. Any adjustments resulting from this review are reflected currently in pre-tax income, except to the extent such adjustment impacts a deferred gain under a retroactive reinsurance agreement, in which case the ceded portion would be amortized into pre-tax income in subsequent periods. Because these estimates are subject to the outcome of future events, changes in estimates are common given that loss trends vary and time is often required for changes in trends to be recognized and confirmed. Given the uncertainties around the impact from the COVID-19 crisis, including the significant global economic slowdown and general market decline, the full impact of COVID-19 and how it may ultimately impact the results of our insurance operations remains uncertain. In addition, in response to the crisis, new governmental, legislative and regulatory initiatives have been put in place and continue to be developed that could result in additional restrictions and requirements relating to our policies that may have a negative impact on our business operations. However, we have recorded our estimate of the ultimate liability for claims that have occurred as of the balance sheet date associated with COVID-19 which reflects our expectations given the current facts and circumstances. We will continue to monitor and review the impact. 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. Our gross loss reserves before reinsurance and discount are net of contractual deductible recoverable amounts due from policyholders of approximately $ 12.6 billion and $ 12.2 billion at December 31, 2020 and 2019, respectively. These recoverable amounts are related to certain policies with high deductibles (in excess of high dollar amounts retained by the insured through self-insured retentions, deductibles, retrospective programs, or captive arrangements, each referred to generically as “deductibles”), primarily for U.S. Commercial casualty business. With respect to the deductible portion of the claim, we manage and pay the entire claim on behalf of the insured and are reimbursed by the insured for the deductible portion of the claim. Thus, these recoverable amounts represent a credit exposure to us. At December 31, 2020 and 2019, we held collateral of approximately $ 9.2 billion and $ 8.9 billion, respectively, for these deductible recoverable amounts, consisting primarily of letters of credit and funded trust agreements. Allowance for credit losses for the unsecured portion of these recoverable amounts was $ 14 million at December 31, 2020. The following table presents the rollforward of activity in Loss Reserves: Years Ended December 31, (in millions) 2020 2019 2018 Liability for unpaid loss and loss adjustment expenses, beginning of year $ 78,328 $ 83,639 $ 78,393 Reinsurance recoverable ( 31,069) ( 31,690) ( 26,708) Initial allowance upon CECL adoption 164 - - Net Liability for unpaid loss and loss adjustment expenses, beginning of year 47,423 51,949 51,685 Losses and loss adjustment expenses incurred: Current year 16,928 17,596 20,534 Prior years, excluding discount and amortization of deferred gain ( 90) ( 340) 1,429 Prior years, discount charge (benefit) 587 1,063 ( 252) Prior years, amortization of deferred gain on retroactive reinsurance (a) ( 237) ( 219) ( 395) Total losses and loss adjustment expenses incurred 17,188 18,100 21,316 Losses and loss adjustment expenses paid: Current year ( 4,062) ( 4,894) ( 5,754) Prior years ( 14,603) ( 18,020) ( 17,768) Total losses and loss adjustment expenses paid ( 18,665) ( 22,914) ( 23,522) Other changes: Foreign exchange effect 815 ( 6) ( 677) Allowance for credit losses ( 15) - - Acquisitions (b) - - 3,284 Retroactive reinsurance adjustment (net of discount) (c) 361 130 ( 137) Fortitude sale (d) ( 3,818) - - Total other changes ( 2,657) 124 2,470 Liability for unpaid loss and loss adjustment expenses, end of year: Net liability for unpaid losses and loss adjustment expenses 43,289 47,259 51,949 Reinsurance recoverable 34,431 31,069 31,690 Total $ 77,720 $ 78,328 $ 83,639 (a) Includes $ 41 million, $ 27 million and $ 51 million for the retroactive reinsurance agreement with NICO covering U.S. asbestos exposures for the year ended December 31, 2020, 2019 and 2018, respectively. (b) Includes amounts related to the acquisition of Glatfelter in October 2018 and Validus in July 2018. (c) Includes benefit (charge) from change in discount on retroactive reinsurance in the amount of $ 340 million, $ 469 million and $( 180) million for the periods ended December 31, 2020, 2019 and 2018, respectively. (d) On June 2, 2020, AIG completed the Majority Interest Fortitude Sale. Concurrent with the Majority Interest Fortitude Sale, AIG established a reinsurance recoverable. Refer to Note 1 for additional information. Prior Year Development During 2020, we recognized favorable prior year loss reserve development of $ 90 million excluding discount and amortization of deferred gain. The development was primarily driven by:  Favorable development on U.S. Workers’ Compensation business, both guaranteed cost business and large deductible, where we reacted to favorable loss trends in recent accident years;  Favorable development across the combination of primary and excess casualty coverages;  Favorable development in Property, Specialty, and other miscellaneous coverages;  Unfavorable development in U.S. Financial Lines, notably D&O, Employment Practices Liability (EPLI), Mergers and Acquisitions, Cyber and Non-Medical Professional Errors & Omissions business where we reacted to increasing frequency and severity in recent accident years;  Unfavorable development in Personal Lines where we reacted to adverse development in Homeowners and Umbrella;  Unfavorable development on Financial Lines driven by low frequency and high severity seen in D&O, especially in UK/Europe and Australia;  Favorable development on Property and Special Risks globally driven by UK/Europe;  Favorable development on Europe and Japan Personal Insurance driven by favorable frequency and severity trends. Our analyses and conclusions about prior year reserves also help inform our judgments about the current accident year loss and loss adjustment expense ratios we selected. During 2019, we recognized favorable prior year loss reserve development of $ 340 million excluding discount and amortization of deferred gain. The development was primarily driven by:  Favorable development on U.S. Workers’ Compensation business, both guaranteed cost business and large deductible and Defense Base Act business (covering government contractors serving at military bases overseas) where we reacted to favorable loss trends in recent accident years;  Favorable development on 2017 Hurricanes (Harvey, Irma and Maria) and favorable development due to 2017 California wildfire subrogation recoverables in Commercial Property and Personal Lines.  Unfavorable development in Primary General Liability where we reacted to adverse frequency and severity trends especially in Construction Wrap business in recent accident years.  Unfavorable development in U.S. Financial Lines, notably D&O, EPLI and Non-Medical Professional Errors & Omissions business where we reacted to increasing frequency and severity in recent accident years.  Unfavorable development on European Casualty & Financial Lines, notably Commercial Auto, Employers Liability, Directors & Officers, and Financial Institutions business; and  Favorable development on Europe Property and Special Risks, Europe and Japan Personal Insurance and Other product lines. Our analyses and conclusions about prior year reserves also help inform our judgments about the current accident year loss and loss adjustment expense ratios we selected. During 2018, we recognized adverse prior year loss reserve development of $ 1.4 billion before impact of the Adverse Development Cover and the asbestos cession to NICO. The key components of this development were as follows:  Unfavorable development in U.S. Excess Casualty, driven by the combination of construction defect and construction wrap claims from accident year 2015 and prior where we reacted to significant increases in severity and longer claim reporting patterns, as well as higher than expected loss severity in accident years 2016 and 2017, which led to an increase in estimates for these accident years;  Unfavorable development in U.S. Financial Lines, primarily from D&O and EPLI policies covering Corporate and National Insureds as well as Private and Not-for-Profit insureds. This development was predominantly in accident years 2014-2017 and resulted largely from increases in severity associated with an increase in frequency of class action lawsuits from those years.  Favorable development in U.S. Commercial Property and Specialty Lines due to reductions in our estimates for 2017 Catastrophes, favorable attritional losses in Commercial Property and favorable Specialty emergence.  Unfavorable development in U.S. Personal Lines reflecting the adverse development on the 2017 California wildfires and Hurricane Irma in 2017.  Unfavorable development in International Financial Lines driven by increased large loss activity in recent accident years, particularly related to directors and officers class action suits against insureds with global exposure. Our analyses and conclusions about prior year reserves also help inform our judgments about the current accident year loss and loss adjustment expense ratios we selected. The table below presents the reconciliation of the net liability for unpaid losses and loss adjustment expenses in the following tables to Loss Reserves in the Consolidated Balance Sheets for the year ended December 31, 2020: Net liability for unpaid losses Reinsurance recoverable on Gross liability and loss adjustment expenses unpaid losses and loss for unpaid as presented in the adjustment expenses included in losses and loss (in millions) disaggregated tables below the disaggregated tables below adjustment expenses U.S. Workers' Compensation (before discount) $ 4,630 $ 6,564 $ 11,194 U.S. Excess Casualty 3,746 4,584 8,330 U.S. Other Casualty 3,520 4,568 8,088 U.S. Financial Lines 4,838 2,193 7,031 U.S. Property and Special Risks 6,181 2,571 8,752 U.S. Personal Insurance 1,116 1,626 2,742 UK/Europe Casualty and Financial lines 6,826 1,225 8,051 UK/Europe Property and Special Risks 2,679 1,215 3,894 UK/Europe and Japan Personal Insurance 2,219 505 2,724 Total $ 35,755 $ 25,051 $ 60,806 Reconciling Items Discount on workers' compensation lines ( 1,636) Other product lines * 15,776 Unallocated loss adjustment expenses 2,774 Total Loss Reserves $ 77,720 * Reinsurance recoverable for other product lines of $ 9.1 billion resulted in a net liability for unpaid losses and loss adjustment expenses of $ 6.7 billion for the year ended December 31, 2020. Loss Development Information The following is information about incurred and paid loss developments as of December 31, 2020, net of reinsurance. The cumulative number of reported claims, the total of IBNR liabilities and expected development on reported loss included within the net incurred loss amounts are presented in the following section. Reserving Methodology We use a combination of methods to project ultimate losses for both long-tail and short-tail exposures, which include:  Paid Development method: The Paid Development method estimates ultimate losses by reviewing paid loss patterns and selecting paid ultimate loss development factors. These factors are then applied to paid losses by applying them to accident years, with further expected changes in paid loss. Since the method does not rely on case reserves, it is not directly influenced by changes in the adequacy of case reserves.  Incurred Development method: The Incurred Development method is similar to the Paid Development method, but it uses case incurred losses instead of paid losses. Since this method uses more data (case reserves in addition to paid losses) than the Paid Development method, the incurred development patterns may be less variable than paid development patterns.  Expected Loss Ratio method: The Expected Loss Ratio method multiplies premiums by an expected loss ratio to produce ultimate loss estimates for each accident year. This method may be useful if loss development patterns are inconsistent, losses emerge very slowly, or there is relatively little loss history from which to estimate future losses.  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. 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 adverse development reinsurance agreement (ADC) in an additional table below our Incurred Losses and Allocated Loss Adjustment Expenses (ALAE) 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. T he 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, 2020. Although this approach requires restating all prior accident year information, the changes in exchange rates do not impact incurred and paid loss development trends.  Acquisitions: We include acquisitions from all accident years presented in the tables. For purposes of this disclosure, we have applied the retrospective method for the acquired reserves, including incurred and paid claim development histories throughout the relevant tables. It should be noted that historical reserves for the acquired businesses were established by the acquired companies using methods, assumptions and procedures then in effect which may differ from our current reserving bases. Accordingly, it may not be appropriate to extrapolate future redundancies or deficiencies based on the aggregated historical results shown in the triangles.  Dispositions: We exclude dispositions from all accident years presented in the tables.  Claim counts: We consider a reported claim to be one claim for each claimant or feature for each loss occurrence. Claims relating to losses that are 100 percent reinsured are excluded from the reported claims in the tables below. Reported claims for losses from assumed reinsurance contracts are not available and hence not included in the reported claims.  There are limitations that should be considered on the reported claim count data in the tables below, including: - Claim counts are presented only on a reported (not an ultimate) basis; - The tables below include lines of business and geographies at a certain aggregated level which may indicate different frequency and severity trends and characteristics, and may not be as meaningful as the claim count information related to the individual products within those lines of business and geographies; - Certain lines of business are more likely to be subject to occurrences involving multiple claimants and features, which can distort measures based on the reported claim counts in the table below; and - Reported claim counts are not adjusted for ceded reinsurance, which may distort the measure of frequency or severity. Supplemental Information: The information about incurred and paid loss development for all periods preceding year ended December 31, 2020 and the related historical claims payout percentage disclosure is unaudited and is presented as supplementary information.

We generally use a combination of loss development, frequency/severity and expected loss ratio methods for workers’ compensation. Many of our primary casualty policies contain risk-sharing features, including high deductibles, self-insured retentions or retrospective rating features, in addition to a traditional insurance component. These risk-sharing programs generally are large and complex, comprising multiple products, years and structures, and are subject to amendment over time. We group guaranteed cost and excess of deductible business separately and then further by state and industry subset to the extent that meaningful differences are determined to exist. We also separately analyze certain subsets of the portfolio that have unique characteristics (e.g., U.S. government sub-contractor accounts and construction wrap-up business). For excess of deductible business, we also segment by size of deductible and whether the claim is handled by AIG or an outside third-party administrator (TPA). The proportion of large deductible business has increased over time, which has slowed the reporting pattern of claims. For guaranteed cost business, expected loss ratio methods generally are given significant weight only in the most recent accident year. Workers’ compensation claims are generally characterized by high frequency, low severity, and relatively consistent loss development from one accident year to the next. We historically have been a leading writer of workers’ compensation, and thus have sufficient volume of claims experience to use development methods. We generally segregate California (CA) and New York (NY) businesses from the other states to reflect their different development patterns and changing percentage of the mix by state. The claims development tables above are impacted by two other significant initiatives, which offset each other. In recent years, we instituted claims strategy changes and loss mitigation efforts to accelerate settlements, which we believe results in an overall reduction in claim costs. This strategy resulted in an increase in paid losses along the latest diagonals relative to prior years. In addition, we have been reducing premium volume in recent years and shifting a greater proportion of business to insured risk retention structures such as high deductible policies. These mix and volume changes slowed paid and incurred development since excess of deductible claims will typically take longer to emerge and settle. Expected loss ratio methods for business written in excess of a deductible may be given significant weight in the most recent five accident years. In the 2016 analysis, we increased our tail factor estimates for states other than NY and CA for guaranteed cost business in recognition of longer medical development patterns that we have been seeing in recent years. We reflected increases in legal costs we have seen across the portfolio, particularly in California. Additionally, over the years we have written a number of very large accounts which include workers’ compensation coverage. These accounts are generally individually priced by our actuaries, and to the extent appropriate, the indicated losses based on the pricing analysis may be used to record the initial estimated loss reserves for these accounts. Prior Year Development During 2020, we recognized $ 367 million of favorable prior year development in U.S. Workers Compensation business due to continued favorable frequency and severity trends seen across the diagonals for many subsets of US Workers Compensation especially for recent accident years. During 2019, we recognized $ 699 million of favorable prior year development in U.S. Workers Compensation business due to favorable frequency and severity trends seen across the diagonals across many subsets of U.S. Workers Compensation especially in the recent accident years. During 2018, we recognized $ 51 million of adverse prior year development in U.S. Workers Compensation business with higher claim development factors at older ages (tail factors) for non-California, non-New York and loss sensitive business in older accident years being offset by favorable emergence in recent years. Accident year 2017 was adversely impacted by a change in ceded reinsurance estimates. For our Defense Base Act business, adverse development in recent years was offset by an expansion of the definition of reimbursable War Hazard claims by the U.S. Government. U.S. Excess Casualty During 2020, we recognized $ 149 million of favorable prior year development in Excess Casualty, net of external reinsurance but before ADC cessions, driven by favorable emergence on older accident years offset by severity increases in recent accident years. During 2019, we recognized $ 76 million of unfavorable prior year development in Excess Casualty, net o

VARIABLE LIFE AND ANNUITY CONTRACTS
VARIABLE LIFE AND ANNUITY CONTRACTS	14. Variable Life and Annuity Contracts We report variable contracts within the separate accounts when investment income and investment gains and losses accrue directly to, and investment risk is borne by, the contract holder and the separate account meets additional accounting criteria to qualify for separate account treatment. The assets supporting the variable portion of variable annuity and variable universal life contracts that qualify for separate account treatment are carried at fair value and reported as Separate account assets, with an equivalent summary total reported as Separate account liabilities. Policy values for variable products and investment contracts are expressed in terms of investment units. Each unit is linked to an asset portfolio. The value of a unit increases or decreases based on the value of the linked asset portfolio. The current liability at any time is the sum of the current unit value of all investment units in the separate accounts, plus any liabilities for guaranteed minimum death benefits (GMDB) or guaranteed minimum withdrawal benefits (GMWB) included in Future policy benefits or Policyholder contract deposits, respectively. Amounts assessed against the contract holders for mortality, administrative and other services are included in revenue. Net investment income, net investment gains and losses, changes in fair value of assets, and policyholder account deposits and withdrawals related to separate accounts are excluded from the Consolidated Statements of Income, Comprehensive Income (Loss) and Cash Flows. Variable annuity contracts may include certain contractually guaranteed benefits to the contract holder. These guaranteed features include GMDB that are payable in the event of death, and living benefits that are payable in the event of annuitization, or, in other instances, at specified dates during the accumulation period. Living benefits primarily include GMWB. A variable annuity contract may include more than one type of guaranteed benefit feature; for example, it may have both a GMDB and a GMWB. However, a policyholder can only receive payout from one guaranteed feature on a contract containing a death benefit and a living benefit, i.e. the features are mutually exclusive (except a surviving spouse who has a rider to potentially collect both a GMDB upon their spouse’s death and a GMWB during their lifetime). A policyholder cannot purchase more than one living benefit on one contract. The net amount at risk for each feature is calculated irrespective of the existence of other features; as a result, the net amount at risk for each feature is not additive to that of other features. Account balances of variable annuity contracts with guarantees were invested in separate account investment options as follows: At December 31, (in millions) 2020 2019 Equity funds $ 56,868 $ 51,383 Bond funds 8,534 7,881 Balanced funds 27,441 26,659 Money market funds 1,124 765 Total $ 93,967 $ 86,688 GMDB Depending on the contract, the GMDB feature may provide a death benefit of either (a) total deposits made to the contract less any partial withdrawals plus a minimum return (and in rare instances, no minimum return) or (b) the highest contract value attained, typically on any anniversary date minus any subsequent withdrawals following the contract anniversary. GMDB is our most widely offered benefit. The liability for GMDB, which is recorded in Future policy benefits, represents the expected value of benefits in excess of the projected account value, with the excess recognized ratably over the accumulation period based on total expected assessments, through Policyholder benefits and losses incurred. The net amount at risk for GMDB represents the amount of benefits in excess of account value if death claims were filed on all contracts on the balance sheet date. The following table presents details concerning our GMDB exposures, by benefit type: At December 31, 2020 2019 Net Deposits Net Deposits Plus a Minimum Highest Contract Plus a Minimum Highest Contract (dollars in millions) Return Value Attained Return Value Attained Account value $ 105,010 $ 16,667 $ 98,386 $ 15,796 Net amount at risk 490 276 689 301 Average attained age of contract holders by product 65 72 65 71 Range of guaranteed minimum return rates 0.00%- 4.50% 0.00%- 4.50% The following summarizes GMDB liability related to variable annuity contracts, excluding assumed reinsurance: Years Ended December 31, (in millions) 2020 2019 2018 Balance, beginning of year $ 407 $ 397 $ 352 Reserve increase (decrease) 41 35 93 Benefits paid ( 43) ( 40) ( 43) Changes in reserves related to unrealized appreciation of investments 16 15 ( 5) Balance, end of year $ 421 $ 407 $ 397 Assumptions used to determine the GMDB liability include interest rates, which vary by year of issuance and products; mortality rates, which are based upon actual experience modified to allow for variations in policy form; lapse rates, which are based upon actual experience modified to allow for variations in policy form; investment returns, based on stochastically generated scenarios; and asset growth assumptions, which include a reversion to the mean methodology, similar to that applied for DAC. We regularly evaluate estimates used to determine the GMDB liability and adjust the additional liability balance, with a related charge or credit to Policyholder benefits and losses incurred, if actual experience or other evidence suggests that earlier assumptions should be revised. GMWB Certain of our variable annuity contracts contain optional GMWB benefits and, to a lesser extent, guaranteed minimum accumulation benefits, which are not currently offered. With a GMWB, the contract holder can monetize the excess of the guaranteed amount over the account value of the contract only through a series of withdrawals that do not exceed a specific percentage per year of the guaranteed amount. If, after the series of withdrawals, the account value is exhausted, the contract holder will receive a series of annuity payments equal to the remaining guaranteed amount, and, for lifetime GMWB products, the annuity payments continue as long as the covered person(s) is living. The liabilities for GMWB, which are recorded in Policyholder contract deposits, are accounted for as embedded derivatives measured at fair value, with changes in the fair value of the liabilities recorded in Net realized capital gains (losses). The fair value of these embedded derivatives was a net liability of $ 3.6 billion and $ 2.5 billion at December 31, 2020 and 2019, respectively. For discussion of the fair value measurement of guaranteed benefits that are accounted for as embedded derivatives see Note 5. We had account values subject to GMWB that totaled $ 48 billion and $ 45 billion at December 31, 2020 and 2019, respectively. The net amount at risk for GMWB represents the present value of minimum guaranteed withdrawal payments, in accordance with contract terms, in excess of account value, assuming no lapses. The net amount at risk related to the GMWB guarantees was $ 1.1 billion and $ 328 million at December 31, 2020 and 2019, respectively. We use derivative instruments and other financial instruments to mitigate a portion of our exposure that arises from GMWB benefits.

AIGLH Junior Subordinated Debentures In connection with our acquisition of AIG Life Holdings, Inc. (AIGLH) in 2001, we entered into arrangements with AIGLH with respect to outstanding AIGLH capital securities. In 1996, AIGLH issued capital securities through a trust to institutional investors and funded the trust with AIGLH junior subordinated debentures issued to the trust with the same terms as the capital securities. On July 11, 2013, the AIGLH junior subordinated debentures were distributed to holders of the capital securities, the capital securities were cancelled and the trusts were dissolved. At December 31, 2020, the junior subordinated debentures outstanding consisted of $ 113 million of 8.5 percent junior subordinated debentures due July 2030, $ 211 million of 8.125 percent junior subordinated debentures due March 2046 and $ 37 million of 7.57 percent junior subordinated debentures due December 2045, each guaranteed by AIG Parent. Credit Facilities We maintain a committed, revolving syndicated credit facility (the Facility) as a potential source of liquidity for general corporate purposes. The Facility provides for aggregate commitments by the bank syndicate to provide unsecured revolving loans and/or standby letters of credit of up to $ 4.5 billion without any limits on the type of borrowings and is scheduled to expire in June 2022. At December 31, 2020 Available Effective (in millions) Size Amount Expiration Date Syndicated Credit Facility $ 4,500 $ 4,500 June 2022 6/27/2017 We also maintain revolving credit facilities that can exclusively be utilized by certain consolidated investment entities to acquire assets related to securitizations. Draws under those credit facilities cannot be utilized for general corporate purposes. Prior to the pricing of the related securitizations, these credit facilities have combined limits of up to $ 390 million. Subsequent to pricing of the related securitizations, the combined limits are expected to increase to up to approximately $ 610 million. As of December 31, 2020, we have drawn $ 84 million under the credit facilities. These credit facilities have maturity dates ranging from one to ten years .

CONTINGENCIES, COMMITMENTS AND GUARANTEES
CONTINGENCIES, COMMITMENTS AND GUARANTEES	16. Contingencies, Commitments and Guarantees In the normal course of business, various contingent liabilities and commitments are entered into by AIG and our subsidiaries. In addition, AIG Parent guarantees various obligations of certain subsidiaries. Although AIG cannot currently quantify its ultimate liability for unresolved litigation and investigation matters, including those referred to below, it is possible that such liability could have a material adverse effect on AIG’s consolidated financial condition or its consolidated results of operations or consolidated cash flows for an individual reporting period. Legal Contingencies Overview In the normal course of business, AIG and our subsidiaries are subject to regulatory and government investigations and actions, and litigation and other forms of dispute resolution in a large number of proceedings pending in various domestic and foreign jurisdictions. Certain of these matters involve potentially significant risk of loss due to potential for significant jury awards and settlements, punitive damages or other penalties. Many of these matters are also highly complex and may seek recovery on behalf of a class or similarly large number of plaintiffs. It is therefore inherently difficult to predict the size or scope of potential future losses arising from these matters. In our insurance and reinsurance operations, litigation and arbitration concerning the scope of coverage under insurance and reinsurance contracts, and litigation and arbitration in which our subsidiaries defend or indemnify their insureds under insurance contracts, are generally considered in the establishment of our loss reserves. Separate and apart from the foregoing matters involving insurance and reinsurance coverage, AIG, our subsidiaries and their respective officers and directors are subject to a variety of additional types of legal proceedings brought by holders of AIG securities, customers, employees and others, alleging, among other things, breach of contractual or fiduciary duties, bad faith, indemnification and violations of federal and state statutes and regulations. With respect to these other categories of matters not arising out of claims for insurance or reinsurance coverage, we establish reserves for loss contingencies when it is probable that a loss will be incurred and the amount of the loss can be reasonably estimated. In many instances, we are unable to determine whether a loss is probable or to reasonably estimate the amount of such a loss and, therefore, the potential future losses arising from legal proceedings may exceed the amount of liabilities that we have recorded in our financial statements covering these matters. While such potential future charges could be material, based on information currently known to management, management does not believe, other than as may be discussed below, that any such charges are likely to have a material adverse effect on our financial position or results of operation. Additionally, from time to time, various regulatory and governmental agencies review the transactions and practices of AIG and our subsidiaries in connection with industry-wide and other inquiries or examinations into, among other matters, the business practices of current and former operating insurance subsidiaries. Such investigations, inquiries or examinations could develop into administrative, civil or criminal proceedings or enforcement actions, in which remedies could include fines, penalties, restitution or alterations in our business practices, and could result in additional expenses, limitations on certain business activities and reputational damage. On July 28, 2020, VALIC Financial Advisors, Inc. (VFA), an indirect subsidiary of AIG, agreed to settle two separate proceedings brought by the SEC without admitting or denying the findings. VFA agreed as part of these settlements to pay disgorgement, prejudgment interest, and civil monetary penalties, as well as to comply with certain undertakings. Tax Litigation We were party to tax litigation before the Southern District of New York (Southern District), which was dismissed by the Southern District in October 2020 based upon the settlement reached between AIG and the government. For additional information see Note 22 to the Consolidated Financial Statements. lease Commitments We lease office space and equipment in various locations across jurisdictions in which the Company operates. The majority of the resulting obligation arising from these contracts is generated by our real estate portfolio, which only includes contracts classified as operating leases. As of December 31, 2020, the lease liability and corresponding right of use asset reflected in Other liabilities Other assets 1.0 billion and $ 906 million, respectively, and we made cash payments of $ 252 million in 2020 in connection with these leases. The liability includes non-lease components, such as property taxes and insurance for our gross leases. Some of these leases contain options to renew after a specified period of time at the prevailing market rate; however, renewal options that have not been exercised as of December 31, 2020 are excluded until management attains a reasonable level of certainty. Some leases also include termination options at specified times and term; however, termination options are not reflected in the lease asset and liability balances until they have been exercised. The weighted average discount rate and lease term assumptions used in determining the liability are 2.50 percent and 8.8 years, respectively. The primary assumption used to determine the discount rate is the cost of funding for the Company, which is based on the secured borrowing rate for terms similar to the lease term, and for the major financial markets in which AIG operates. Rent expense was $ 258 million, $ 232 million and $ 283 million for the years ended December 31, 2020, 2019 and 2018, respectively. The following table presents the future undiscounted cash flows under operating leases at December 31, 2020: (in millions) 2021 $ 233 2022 177 2023 138 2024 111 2025 81 Remaining years after 2025 506 Total undiscounted lease payments $ 1,246 Less: Present value adjustment 202 Net lease liabilities 1,044 During 2019, we recognized a pretax net gain of $ 200 million from the sale and concurrent leaseback of our corporate headquarters. We also procured additional office space via operating lease contracts for which lease commencement will occur in 2021. Future undiscounted obligations stemming from those contracts total $ 389 million, which excludes the effect of renewal options. Other Commitments In the normal course of business, we enter into commitments to invest in limited partnerships, private equity funds and hedge funds and to purchase and develop real estate in the U.S. and abroad. These commitments totaled $ 7.3 billion at December 31, 2020. Guarantees Subsidiaries We have issued unconditional guarantees with respect to the prompt payment, when due, of all present and future payment obligations and liabilities of AIG Financial Products Corp. and related subsidiaries (collectively AIGFP) and of AIG Markets, Inc. (AIG Markets) arising from transactions entered into by AIG Markets. In connection with AIGFP’s business activities, AIGFP has issued, in a limited number of transactions, standby letters of credit or similar facilities to equity investors of structured leasing transactions in an amount equal to the termination value owing to the equity investor by the lessee in the event of a lessee default (the equity termination value). The total amount outstanding at December 31, 2020 was $ 78 million. In those transactions, AIGFP has agreed to pay such amount if the lessee fails to pay. The amount payable by AIGFP is, in certain cases, partially offset by amounts payable under other instruments typically equal to the present value of scheduled payments to be made by AIGFP. In the event that AIGFP is required to make a payment to the equity investor, the lessee is unconditionally obligated to reimburse AIGFP. To the extent that the equity investor is paid the equity termination value from the standby letter of credit and/or other sources, including payments by the lessee, AIGFP takes an assignment of the equity investor’s rights under the lease of the underlying property. Because the obligations of the lessee under the lease transactions are generally economically defeased, lessee bankruptcy is the most likely circumstance in which AIGFP would be required to pay without reimbursement. AIG Parent files a consolidated federal income tax return with certain subsidiaries and acts as an agent for the consolidated tax group when making payments to the Internal Revenue Service (IRS). AIG Parent and its subsidiaries have adopted, pursuant to a written agreement, a method of allocating consolidated federal income taxes. Under an Amended and Restated Tax Payment Allocation Agreement dated June 6, 2011 between AIG Parent and one of its Bermuda-domiciled insurance subsidiaries, AIG Life of Bermuda, Ltd. (AIGB), AIG Parent has agreed to indemnify AIGB for any tax liability (including interest and penalties) resulting from adjustments made by the IRS or other appropriate authorities to taxable income, special deductions or credits in connection with investments made by AIGB in certain affiliated entities. Asset Dispositions We are subject to financial guarantees and indemnity arrangements in connection with the completed sales of businesses. The various arrangements may be triggered by, among other things, declines in asset values, the occurrence of specified business contingencies, the realization of contingent liabilities, developments in litigation or breaches of representations, warranties or covenants provided by us. These arrangements are typically subject to various time limitations, defined by the contract or by operation of law, such as statutes of limitation. In some cases, the maximum potential obligation is subject to contractual limitations, while in other cases such limitations are not specified or are not applicable. The Majority Interest Fortitude Sale is subject to a post-closing purchase price adjustment pursuant to which AIG will pay Fortitude Re for certain adverse development in property casualty related reserves, based on an agreed methodology, that may occur on or prior to December 31, 2023, up to a maximum of $ 500 million. We are unable to develop a reasonable estimate of the maximum potential payout under certain of these arrangements. Overall, we believe the likelihood that we will have to make any material payments related to completed sales under these arrangements is remote, and no material liabilities related to these arrangements have been recorded in the Consolidated Balance Sheets. For additional discussion on the Fortitude Re transaction, see Note 1 to the Consolidated Financial Statements.

EQUITY	17. Equity Shares Outstanding Preferred Stock On March 14, 2019, we issued 20,000 shares of Series A 5.85% Non-Cumulative Perpetual Preferred Stock (Series A Preferred Stock) (equivalent to 20,000,000 Depositary Shares, each representing a 1/1,000th interest in a share of Series A Preferred Stock), $ 5.00 par value and $ 25,000 liquidation preference per share (equivalent to $ 25 per Depositary Share). After underwriting discounts and expenses, we received net proceeds of approximately $ 485 million. We may redeem the Series A Preferred Stock at our option, (a) in whole, but not in part, at any time prior to March 15, 2024, within 90 days after the occurrence of a “Rating Agency Event,” at a redemption price equal to $ 25,500 per share of the Series A Preferred Stock (equivalent to $ 25.50 per Depositary Share), plus an amount equal to any dividends per share that have been declared but not paid prior to the redemption date (but no amount due in respect of any dividends that have not been declared prior to such date), or (b) (i) in whole, but not in part, at any time prior to March 15, 2024, within 90 days after the occurrence of a “Regulatory Capital Event,” or (ii) in whole or in part, from time to time, on or after March 15, 2024, in each case, at a redemption price equal to $ 25,000 per share of the Series A Preferred Stock (equivalent to $ 25.00 per Depositary Share), plus an amount equal to any dividends per share that have been declared but not paid prior to the redemption date (but no amount due in respect of any dividends that have not been declared prior to such date). A “Rating Agency Event” is generally defined to mean that any nationally recognized statistical rating organization within the meaning of Section 3(a)(62) of the Securities Exchange Act of 1934, as amended (the Exchange Act) that then publishes a rating for us amends, clarifies or changes the criteria it uses to assign equity credit to securities such as the Series A Preferred Stock, which amendment, clarification or change results in the shortening of the length of time the Series A Preferred Stock is assigned a particular level of equity credit by that rating agency as compared to the length of time it would have been assigned that level of equity credit by that rating agency or its predecessor on the initial issuance of the Series A Preferred Stock, or the lowering of the equity credit (including up to a lesser amount) assigned to the Series A Preferred Stock by that rating agency as compared to the equity credit assigned by that rating agency or its predecessor on the initial issuance of the Series A Preferred Stock. A “Regulatory Capital Event” is generally defined to mean our good faith determination that as a result of a change in law, rule or regulation, or a proposed change or an official judicial or administrative pronouncement, there is more than an insubstantial risk that the full liquidation preference of the Series A Preferred Stock would not qualify as capital (or a substantially similar concept) for purposes of any group capital standard to which we are or will be subject. Holders of the Series A Preferred Stock will be entitled to receive dividend payments only when, as and if declared by our board of directors (or a duly authorized committee of the board). Dividends will be payable from the original date of issue at a rate of 5.85% per annum, payable quarterly, in arrears, on the fifteenth day of March, June, September and December of each year, beginning on June 15, 2019. Dividends on the Series A Preferred Stock will be non-cumulative. In the event of any liquidation, dissolution or winding-up of the affairs of AIG, whether voluntary or involuntary, before any distribution or payment out of our assets may be made to or set aside for the holders of any junior stock, holders of the Series A Preferred Stock will be entitled to receive out of our assets legally available for distribution to our stockholders, an amount equal to $ 25,000 per share of Series A Preferred Stock (equivalent to $ 25.00 per Depositary Share), together with an amount equal to all declared and unpaid dividends (if any), but no amount in respect of any undeclared dividends prior to such payment date. Distributions will be made only to the extent of our assets that are available for distribution to stockholders (i.e., after satisfaction of all our liabilities to creditors, if any). The Series A Preferred Stock does not have voting rights, except in limited circumstances, including in the case of certain dividend non-payments. The following table presents declaration date, record date, payment date and dividends paid per preferred share and per depository share on the Series A Preferred Stock in the twelve months ended December 31, 2020 and 2019: Dividends Paid Declaration Date Record Date Payment Date Per Preferred Share Per Depositary Share November 5, 2020 November 30, 2020 December 15, 2020 $ 365.625 $ 0.365625 August 3, 2020 August 31, 2020 September 15, 2020 365.625 0.365625 May 4, 2020 May 29, 2020 June 15, 2020 365.625 0.365625 February 12, 2020 February 28, 2020 March 16, 2020 365.625 0.365625 October 31, 2019 November 29, 2019 December 16, 2019 $ 365.625 $ 0.365625 August 7, 2019 August 30, 2019 September 16, 2019 365.625 0.365625 May 21, 2019 May 31, 2019 June 17, 2019 369.6875 0.3696875 Common Stock The following table presents a rollforward of outstanding shares: Common Treasury Common Stock Stock Issued Stock Outstanding Year Ended December 31, 2018 Shares, beginning of year 1,906,671,492 ( 1,007,626,835) 899,044,657 Shares issued - 4,091,922 4,091,922 Shares repurchased - ( 36,527,150) ( 36,527,150) Shares, end of year 1,906,671,492 ( 1,040,062,063) 866,609,429 Year Ended December 31, 2019 Shares, beginning of year 1,906,671,492 ( 1,040,062,063) 866,609,429 Shares issued - 3,389,602 3,389,602 Shares repurchased - - - Shares, end of year 1,906,671,492 ( 1,036,672,461) 869,999,031 Year Ended December 31, 2020 Shares, beginning of year 1,906,671,492 ( 1,036,672,461) 869,999,031 Shares issued - 3,719,970 3,719,970 Shares repurchased - ( 12,160,952) ( 12,160,952) Shares, end of year 1,906,671,492 ( 1,045,113,443) 861,558,049 Dividends Dividends are payable on AIG Common Stock only when, as and if declared by our Board of Directors in its discretion, from funds legally available for this purpose. In considering whether to pay a dividend on or purchase shares of AIG Common Stock, our Board of Directors considers a number of factors, including, but not limited to: the capital resources available to support our insurance operations and business strategies, AIG’s funding capacity and capital resources in comparison to internal benchmarks, expectations for capital generation, rating agency expectations for capital, regulatory standards for capital and capital distributions, and such other factors as our Board of Directors may deem relevant. The payment of dividends is also subject to the terms of AIG’s outstanding Series A Preferred Stock, pursuant to which no dividends may be declared or paid on any AIG Common Stock unless the full dividends for the latest completed dividend period on all outstanding shares of Series A Preferred Stock have been declared and paid or provided for.

On February 13, 2019, our Board of Directors authorized an additional increase of approximately $ 1.5 billion to its previous share repurchase authorization. As of December 31, 2020, approximately $ 1.5 billion remained under our share repurchase authorization. Shares may be repurchased from time to time in the open market, private purchases, through forward, derivative, accelerated repurchase or automatic repurchase transactions or otherwise (including through the purchase of warrants). Certain of our share repurchases have been and may from time to time be effected through Exchange Act Rule 10b5-1 repurchase plans. In February 2020, we executed an accelerated stock repurchase (ASR) agreement with a third-party financial institution. The total number of shares of AIG Common Stock repurchased in the year ended December 31, 2020, and the aggregate purchase price of those shares, reflect our payment of $ 500 million in the aggregate under the ASR agreement and the receipt of approximately 12 million shares of AIG Common Stock in the aggregate. The timing of any future repurchases will depend on market conditions, our business and strategic plans, financial condition, results of operations, liquidity and other factors. The repurchase of AIG Common Stock is also subject to the terms of AIG’s outstanding Series A Preferred Stock, pursuant to which AIG may not (other than in limited circumstances) purchase, redeem or otherwise acquire AIG Common Stock unless the full dividends for the latest completed dividend period on all outstanding shares of Series A Preferred Stock have been declared and paid or provided for.

EARNINGS PER COMMON SHARE (EPS)	18. Earnings Per Common Share (EPS) The basic EPS computation is based on the weighted average number of common shares outstanding, adjusted to reflect all stock dividends and stock splits. The diluted EPS computation is based on those shares used in the basic EPS computation plus common shares that would have been outstanding assuming issuance of common shares for all dilutive potential common shares outstanding and adjusted to reflect all stock dividends and stock splits. The following table presents the computation of basic and diluted EPS: Years Ended December 31, (dollars in millions, except per common share data) 2020 2019 2018 Numerator for EPS: Income (loss) from continuing operations $ ( 5,833) $ 4,121 $ 103 Less: Net income from continuing operations attributable to noncontrolling interests 115 821 67 Less: Preferred stock dividends 29 22 - Income (loss) attributable to AIG common shareholders from continuing operations ( 5,977) 3,278 36 Income (loss) from discontinued operations, net of income tax expense 4 48 ( 42) Net income (loss) attributable to AIG common shareholders $ ( 5,973) $ 3,326 $ ( 6) Denominator for EPS: Weighted average common shares outstanding – basic 869,309,458 876,750,264 898,405,537 Dilutive common shares - 12,761,682 11,735,705 Weighted average common shares outstanding – diluted (a)(b) 869,309,458 889,511,946 910,141,242 Income (loss) per common share attributable to AIG common shareholders: Basic: Income (loss) from continuing operations $ ( 6.88) $ 3.74 $ 0.04 Income (loss) from discontinued operations $ - $ 0.05 $ ( 0.05) Income (loss) attributable to AIG common shareholders $ ( 6.88) $ 3.79 $ ( 0.01) Diluted: Income (loss) from continuing operations $ ( 6.88) $ 3.69 $ 0.04 Income (loss) from discontinued operations $ - $ 0.05 $ ( 0.05) Income (loss) attributable to AIG common shareholders $ ( 6.88) $ 3.74 $ ( 0.01) (a) For the year ended December 31, 2020, because we reported a net loss attributable to AIG common shareholders, all common stock equivalents are anti-dilutive and are therefore excluded from the calculation of diluted shares and diluted per share amounts. The number of common shares excluded from the calculation was 5,401,597 shares. (b) Dilutive common shares included our share-based employee compensation plans, and a weighted average portion of the 10-year warrants issued to AIG shareholders as part of AIG’s recapitalization in January 2011, which expired in January 2021. The number of common shares excluded from diluted shares outstanding was 68.7 million, 20.0 million and 19.6 million for the years ended December 31, 2020, 2019 and 2018, respectively, because the effect of including those common shares in the calculation would have been anti-dilutive.

STATUTORY FINANCIAL DATA AND RESTRICTIONS
STATUTORY FINANCIAL DATA AND RESTRICTIONS	19. Statutory Financial Data and Restrictions The following table presents statutory net income (loss) and capital and surplus for our General Insurance companies and our Life and Retirement companies in accordance with statutory accounting practices: (in millions) 2020 2019 2018 Years Ended December 31, Statutory net income (loss) (a)(b) General Insurance companies: Domestic $ 915 $ 1,481 $ ( 1,030) Foreign 949 1,384 558 Total General Insurance companies $ 1,864 $ 2,865 $ ( 472) Life and Retirement companies: Domestic $ 680 $ 325 $ 671 Foreign 14 3,336 ( 553) Total Life and Retirement companies $ 694 $ 3,661 $ 118 At December 31, Statutory capital and surplus (a)(b) General Insurance companies: Domestic $ 17,926 $ 17,418 Foreign 15,592 16,409 Total General Insurance companies $ 33,518 $ 33,827 Life and Retirement companies: Domestic $ 10,960 $ 9,228 Foreign 671 5,231 Total Life and Retirement companies $ 11,631 $ 14,459 Aggregate minimum required statutory capital and surplus: General Insurance companies: Domestic $ 3,817 $ 4,177 Foreign 7,303 8,080 Total General Insurance companies $ 11,120 $ 12,257 Life and Retirement companies: Domestic $ 3,574 $ 3,357 Foreign 207 1,137 Total Life and Retirement companies $ 3,781 $ 4,494 (a) Excludes discontinued operations and other divested businesses. Statutory capital and surplus and net income (loss) with respect to foreign operations are as of November 30. (b) The 2020 amounts reflect our best estimate of the statutory net income, capital and surplus as of the date of AIG’s Form 10-K filing. In aggregate, the 2019 General Insurance companies and Life and Retirement companies statutory net income decreased by $ 4 million and the 2019 General Insurance companies and Life and Retirement companies statutory capital and surplus increased by $ 132 million, compared to the amounts previously reported in our Annual Report on Form 10-K for the year ended December 31, 2019, due to finalization of statutory filings and revision of prior period numbers. Our insurance subsidiaries file financial statements prepared in accordance with statutory accounting practices prescribed or permitted by domestic and foreign insurance regulatory authorities. The principal differences between statutory financial statements and financial statements prepared in accordance with U.S. GAAP for domestic companies are that statutory financial statements do not reflect DAC, some bond portfolios may be carried at amortized cost, investment impairments are determined in accordance with statutory accounting practices, assets and liabilities are presented net of reinsurance, policyholder liabilities are generally valued using more conservative assumptions and certain assets are non-admitted. For domestic insurance subsidiaries, aggregate minimum required statutory capital and surplus is based on the greater of the RBC level that would trigger regulatory action or minimum requirements per state insurance regulation. Capital and surplus requirements of our foreign subsidiaries differ from those prescribed in the U.S., and can vary significantly by jurisdiction. At both December 31, 2020 and 2019, all domestic and foreign insurance subsidiaries individually exceeded the minimum required statutory capital and surplus requirements and all domestic insurance subsidiaries individually exceeded RBC minimum required levels. At December 31, 2020 and 2019, our domestic insurance subsidiaries used the following permitted practices that resulted in reported statutory surplus or risk-based capital that is significantly different from the statutory surplus or risk based capital that would have been reported had NAIC statutory accounting practices or the prescribed regulatory accounting practices of their respective state regulator been followed in all respects:  Effective December 31, 2019 and subsequent reporting periods through September 30, 2020, a domestic life insurance subsidiary domiciled in Texas adopted a permitted statutory accounting practice to recognize an admitted asset related to the notional value of coverage defined in an excess of loss reinsurance agreement, net of specified amounts. This reinsurance agreement has a 20-year term and provides coverage to the subsidiary for aggregate claims incurred during the agreement term associated with guaranteed minimum withdrawal benefits on certain fixed index annuities generally issued prior to April 2019 (Block 1) exceeding an attachment point defined in the treaty.  Effective October 1, 2020 and subsequent reporting periods through September 30, 2023, this permitted practice was expanded to similarly recognize an additional admitted asset related to the notional value of coverage defined in a separate excess of loss reinsurance agreement, net of specified amounts. This additional reinsurance agreement has a 25-year term and provides coverage to the subsidiary for aggregate excess of loss claims associated with guaranteed minimum withdrawal benefits on a block of fixed index annuities generally issued in April 2019 or later, including new business issued after the effective date (Block 2). In addition, effective December 31, 2020, this expanded permitted practice also extended the term of the permitted practice for Block 1 from September 30, 2020 to September 30, 2023. The reinsurance agreement covering contracts in Block 1 was also amended to conform certain provisions to be consistent with the Block 2 reinsurance agreement. The permitted practice allows the subsidiary to manage its reserves in a manner more in line with anticipated principle-based reserving requirements once they have been developed. This permitted practice resulted in an increase in the statutory surplus of this subsidiary of approximately $ 614 million and $ 285 million at December 31, 2020 and 2019, respectively. The subsidiary may seek continuation of the permitted practice beyond September 30, 2023, subject to the approval of its domiciliary regulator.  As described in Note 13, our domestic property and casualty insurance subsidiaries domiciled in New York, Pennsylvania and Delaware discount non-tabular workers’ compensation reserves based on applicable prescribed or approved regulations, or in the case of our Delaware subsidiary, based on a permitted practice. This practice did not have a material impact on our statutory surplus, statutory net income (loss) or risk-based capital. Regulation XXX requires U.S. life insurers to establish additional statutory reserves for term life insurance policies with long-term premium guarantees and universal life policies with secondary guarantees (ULSGs). In addition, Guideline AXXX clarifies the application of Regulation XXX as to these guarantees, including certain ULSGs. Our domestic life insurance subsidiaries manage the capital impact of statutory reserve requirements under Regulation XXX and Guideline AXXX through unaffiliated and affiliated reinsurance transactions. The affiliated life insurers providing reinsurance capacity for such transactions are fully licensed insurance companies and are not formed under captive insurance laws. Under the other intercompany reinsurance arrangement, certain Regulation XXX and Guideline AXXX reserves related to a closed block of in-force business are ceded to an affiliated off-shore life insurer, which is licensed as a class E insurer under Bermuda law. This reinsurance arrangement does not meet the criteria for reinsurance accounting under U.S. GAAP; therefore, deposit accounting is applied by the assuming off-shore life insurer. Letters of credit are used to support the credit for reinsurance provided by the affiliated off-shore life insurer. For additional information regarding these letters of credit see Note 8. Subsidiary Dividend Restrictions Payments of dividends to us by our insurance subsidiaries are subject to certain restrictions imposed by regulatory authorities. With respect to our domestic insurance subsidiaries, the payment of any dividend requires formal notice to the insurance department in which the particular insurance subsidiary is domiciled. For example, unless permitted by the Superintendent of Financial Services, property casualty companies domiciled in New York generally may not pay dividends to shareholders that, in any 12-month period, exceed the lesser of 10 percent of such company’s statutory policyholders’ surplus or 100 percent of its “adjusted net investment income,” for the previous year, as defined. Generally, less severe restrictions applicable to both property casualty and life insurance companies exist in most of the other states in which our insurance subsidiaries are domiciled. Under the laws of many states, an insurer may pay a dividend without prior approval of the insurance regulator when the amount of the dividend is below certain regulatory thresholds. Other foreign jurisdictions may restrict the ability of our foreign insurance subsidiaries to pay dividends. Various other regulatory restrictions also limit cash loans and advances to us by our subsidiaries. Largely as a result of these restrictions, approximately $ 41.6 billion of the statutory capital and surplus of our consolidated insurance subsidiaries were restricted from transfer to AIG Parent without prior approval of state insurance regulators at December 31, 2020. To our knowledge, no AIG insurance company is currently on any regulatory or similar “watch list” with regard to solvency. Parent Company Dividend Restrictions At December 31, 2020, our ability to pay dividends is not subject to any significant contractual restrictions, but remains subject to regulatory restrictions. For additional information about our ability to pay dividends to our shareholders see Note 17.

SHARE-BASED COMPENSATION PLANS
SHARE-BASED COMPENSATION PLANS	20. Share-Based Compensation Plans The following table presents our total share-based compensation expense: Years Ended December 31, (in millions) 2020 2019 2018 Share-based compensation expense - pre-tax (a) $ 274 $ 314 $ 337 Share-based compensation expense - after tax (b) 216 248 266 (a) As a result of accelerated vesting events, such as retirement eligibility in the year of grant and involuntary terminations, we recognized $ 63 million, $ 82 million and $ 104 million in 2020, 2019 and 2018, respectively, prior to the end of the specified vesting periods. It is our policy to reverse compensation expense for forfeited awards when they occur. (b) We also recognized $ 25 million of additional tax expense due to share settlements occurring in 2020. Employee Plans The Company sponsors several stock compensation programs under the AIG Long Term Incentive Plan (as amended) and its predecessor plan, the AIG 2013 Long Term Incentive Plan (each as applicable, the LTIP), which are governed by the AIG 2013 Omnibus Incentive Plan (Omnibus Plan). Our share-settled awards are settled with previously acquired shares held in AIG’s treasury. AIG 2013 Omnibus Incentive Plan The Omnibus Plan, which replaced the AIG 2010 Stock Incentive Plan (2010 Plan), was adopted at the 2013 Annual Meeting of Shareholders and provides for the grants of share-based awards to our employees and non-employee directors. The total number of shares that may be granted under the Omnibus Plan (the reserve) is the sum of 1) 45 million shares of AIG Common Stock, plus 2) the number of authorized shares that remained available for issuance under the 2010 Plan when the Omnibus Plan became effective, plus 3) the number of shares of AIG Common Stock relating to outstanding awards under the 2010 Plan at the time the Omnibus Plan became effective that subsequently are forfeited, expired, terminated or otherwise lapse or are settled in cash. Each share-based unit granted under the Omnibus Plan reduces the number of shares available for future grants by one share. However, shares with respect to awards that are forfeited, expired or settled for cash, and shares withheld for taxes on awards (other than options and stock appreciation rights awards) are returned to the reserve. During 2020, performance share units (PSUs), restricted stock units (RSUs), stock options and deferred stock units (DSUs) (collectively, units) were granted under the Omnibus Plan and 21,892,781 shares are available for future grants as of December 31, 2020. Units are issued to employees as part of our long-term incentive program, generally in March of any given year, and are also issued for off-cycle grants, which are made from time to time during the year generally as sign-on awards to new hires or as a result of a change in employee status. AIG Long Term Incentive Plan Long-Term Incentive (LTI) Awards The LTIP provides for an annual award to certain employees, including our senior executive officers and other highly compensated employees that may be comprised of a combination of one or more of the following units: PSUs, RSUs or stock options. The number of PSUs issued on the grant date (the target) provides the opportunity for LTIP participants (usually senior management) to receive shares of AIG Common Stock based on AIG achieving specified performance goals at the end of a three-year zero to 200 percent of the target for the 2020, 2019 and 2018 awards, depending on AIG’s performance relative to a specified peer group and/or the outcome of pre-established financial goals, as applicable. RSUs and stock options are earned based solely on continued service by the participant. Vesting occurs on January 1 of the year immediately following the end of the three-year three equal installments beginning on January 1 of the year immediately following the end of a performance period and January 1 of each of the next two years. Recipients must be employed at each vesting date to be entitled to share delivery, except upon the occurrence of an accelerated vesting event, such as an involuntary termination without cause, disability, retirement eligibility or death during the vesting period. LTI awards accrue dividend equivalent units (DEUs) in the form of additional PSUs and/or RSUs whenever a cash dividend is declared on shares of AIG Common Stock; the DEUs are subject to the same vesting terms and conditions as the underlying unit. Unit Valuation The fair value of time-vesting RSUs as well as PSUs that are earned based on certain company-specific metrics was based on the closing price of AIG Common Stock on the grant date; while the fair value of PSUs that are earned based on AIG’s relative total shareholder return (TSR) was determined on the grant date using a Monte Carlo simulation. The following table presents the assumptions used to estimate the fair value of PSUs that vest based on AIG’s TSR: 2020 Expected dividend yield (a) - % Expected volatility (b) 46.43 % Risk-free interest rate (c) 0.18 % (a) The award agreement provides that TSR for AIG and each member of the Peer Group will be calculated assuming dividends distributed are reinvested on the ex-dividend date. (b) We used the historical volatility over the most recent 2.50-year period for AIG and the members of the Peer Group, commensurate with the remaining Performance Period as of the Valuation Date. (c) We converted the semi-annual zero-coupon U.S. Treasury rates as of the Valuation Date to continuously compounded rates. We then chose the continuously compounded risk-free rate that is commensurate with the length of the remaining performance period as of the valuation date and interpolated between the yields of the two-year three-year Modification of LTI awards During the third quarter of 2019, we added a modifier to the 2019 performance share units awarded to certain senior executives to cap payout at 100 percent of target if our total shareholder return for the three-year During the third quarter of 2020, we reduced the performance goals from three to two metrics for the 2018 LTI and 2019 LTI awards for certain PSU recipients, which resulted in a net credit of $ 4 million pre-tax to compensation expense. The modification did not apply to the Company’s senior executives. The following table summarizes outstanding share-settled LTI awards (a) Weighted Average As of or for the Year Number of Units Grant-Date Fair Value Ended December 31, 2020 (b) 2020 LTI 2019 LTI 2018 LTI 2016 LTI 2020 LTI 2019 LTI 2018 LTI 2016 LTI Unvested, beginning of year - 4,523,898 2,656,994 223,364 $ - $ 44.98 $ 55.21 $ 62.14 Granted 7,281,247 109,479 79,294 - 31.37 28.16 28.16 - Vested (c) ( 1,788,974) ( 599,606) ( 2,338,209) ( 203,533) 31.46 45.14 55.35 62.14 Forfeited (d) ( 143,617) ( 536,352) ( 398,079) ( 19,831) 32.00 44.55 54.92 62.13 Unvested, end of year (e) 5,348,656 3,497,419 - - $ 31.33 $ 44.79 $ - $ - (a) Excludes stock options, other RSUs and DSUs, which are discussed under Stock Options, Other RSU Grants and Non-Employee Plan, respectively. The 2017 LTI was fully vested in 2019 as a result of the three-year cliff vesting schedule. (b) Except for the 2016 LTI awards, PSUs represent target amount granted, and does not reflect potential increases or decreases that could result from the final outcome of the performance goals for the respective awards, which is determined by the CMRC in the quarter after the applicable performance period ends. (c) Also reflects units that vest as a result of an accelerated vesting event that occurred prior to the specified vesting date. (d) Includes PSUs for which the performance metric was not met at the end of the performance period. (e) At December 31, 2020, the total unrecognized compensation cost for outstanding RSUs and PSUs was $ 178 million and the weighted-average and expected period of years over which that cost is expected to be recognized are 0.94 year and 2 years. Stock Options Stock options were issued as part of the 2020, 2019 and 2018 LTI awards, and to certain newly hired senior executives in 2017 and 2018. Option awards are generally granted with an exercise price equal to the market price of the company’s stock on the grant date. The fair value of the options was estimated on the grant date using the Black-Scholes model for the time-vesting options, and a Monte Carlo simulation for the hurdle-vesting options using the assumptions noted in the following table. The following weighted-average assumptions were used for stock options granted: 2020 2019 2018 Expected annual dividend yield (a) 3.97 % 2.86 % 2.32 % Expected volatility (b) 42.03 % 23.17 % 23.29 % Risk-free interest rate (c) 0.57 % 2.47 % 2.83 % Expected term (d) 6.39 years 6.38 years 4.50 - 6.47 years (a) The dividend yield is the projected annualized AIG dividend yield estimated by Bloomberg Professional service as of the valuation date. (b) The expected volatility is based on the implied volatility of 24 months stock option estimated by the Bloomberg Professional service as of the valuation date. (c) The risk-free interest rate is the continuously compounded interest rate for the term between the valuation date and the expiration date that is assumed to be constant and equal to the interpolated value between the closet data points on the U.S. dollar LIBOR-swap curve as of the valuation date. (d) The contractual terms are 7 and 10 years from the date of grant. The following table provides a rollforward of stock option activity: Weighted Average Aggregate As of or for the Year Weighted Average Remaining Intrinsic Values Ended December 31, 2020 Units Exercise Price Contractual Life (in millions) Outstanding, beginning of year 8,365,891 $ 53.66 7.65 Granted 3,303,587 32.25 Exercised ( 74,740) 40.76 Forfeited or expired ( 165,247) 45.42 Outstanding, end of year 11,429,491 $ 47.67 7.59 $ 18 Exercisable, end of year 3,988,609 $ 54.46 6.86 $ 1 The weighted average grant-date fair value of stock options granted during 2020, 2019 and 2018 was $ 9.61, $ 10.01 and $ 11.08, respectively. As of December 31, 2020, we recognized $ 28.1 million of expense, while $ 21 million was unrecognized and is expected to be amortized up to 2.00 years. Other RSU Grants The Company may issue time-vesting RSUs for various reasons including, as a sign-on bonus, retention grant or replacement award in an acquisition. Vesting for these awards generally ranges from 1 to 3 years and is contingent on continuous service. The following table summarizes outstanding share-settled RSU grants. Weighted Average As of or for the Year Number of Units Grant-Date Fair Value Ended December 31, 2020 2019 2018 2020 2019 2018 Unvested, beginning of year 1,231,185 1,634,610 595,250 $ 54.17 $ 56.11 $ 62.93 Granted 583,068 399,779 1,385,929 35.54 52.40 54.07 Vested ( 535,220) ( 774,350) ( 342,481) 50.89 57.32 59.68 Forfeited ( 127,653) ( 28,854) ( 4,088) 54.90 55.23 60.31 Unvested, end of year 1,151,380 1,231,185 1,634,610 $ 46.18 $ 54.17 $ 56.11 We recognized $ 23.7 million of expense related to these RSU grants in 2020. Total unrecognized compensation cost related to these grants was $ 25 million and the weighted-average and expected period of years over which that cost is expected to be recognized are 1.36 years and 5.00 years at December 31, 2020. Non-Employee Plan Our non-employee directors, who serve on our Board of Directors, receive share-based compensation in the form of fully vested DSUs with delivery deferred until retirement from the Board. DSUs granted in 2020, 2019 and 2018 accrue DEUs equal to the amount of any regular quarterly dividend that would have been paid by AIG if the shares of AIG Common Stock underlying the DSUs had been outstanding. In 2020, 2019 and 2018, we granted to non-employee directors 94,062, 49,706 and 39,092 DSUs, respectively, under the 2013 Plan, and recognized expense of $ 2.4 million, $ 2.6 million and $ 2.1 million, respectively.

EMPLOYEE BENEFITS

EMPLOYEE BENEFITS	12 Months Ended

EMPLOYEE BENEFITS
EMPLOYEE BENEFITS	21. Employee Benefits Pension Plans We offer various defined benefit plans to eligible employees. Effective January 1, 2016, the U.S. defined benefit pension plans were frozen. Consequently, these plans are closed to new participants and current participants no longer earn benefits. The U.S. AIG Retirement Plan (the qualified plan) is a noncontributory defined benefit plan subject to the provisions of ERISA. In 2012, the qualified plan was converted to a cash balance formula comprised of pay credits based on six percent of a plan participant’s annual compensation (subject to IRS limitations) and annual interest credits. Although benefits are frozen, these interest credits continue to accrue on the cash balance accounts of active participants, who also accrue years of service for purposes of early retirement eligibility and subsidies. Employees can take their vested benefits when they leave AIG as a lump sum or an annuity option. Employees satisfying certain age and service requirements (i.e., grandfathered employees) remain covered under the average pay formula that was in effect prior to the conversion. The final average pay formula is based upon a percentage of final average compensation multiplied by years of credited service, up to 44 years. Grandfathered employees will receive the higher of the benefit under the cash balance formula or the final average pay formula at retirement. In the U.S. we also sponsor non-qualified unfunded defined benefit plans, such as the AIG Non-Qualified Retirement Income Plan (AIG NQRIP) for certain employees, including key executives, designed to supplement pension benefits provided by the qualified plan. The AIG NQRIP provides a benefit equal to the reduction in benefits under the qualified plan as a result of federal tax limitations on compensation and benefits payable. Non-U.S. defined benefit plans generally are either based on the employee’s years of credited service and compensation in the years preceding retirement or on points accumulated based on the employee’s job grade and other factors during each year of service. Postretirement Plans U.S. postretirement medical and life insurance benefits are based upon the employee attaining the age of 55 and having a minimum of ten years of service, which was reduced to 5 years in 2019 for medical coverage only. Eligible employees who have medical coverage can enroll in retiree medical upon termination of employment. Medical benefits are contributory, while the life insurance benefits, which are closed to new employees, are generally non-contributory. Retiree medical contributions vary from none for pre-1989 retirees to actual premium payments reduced by certain subsidies for post-1992 retirees. These retiree contributions are subject to annual adjustments. Other cost sharing features of the medical plan include deductibles, coinsurance, Medicare coordination, and an employer subsidy for grandfathered employees only. Postretirement benefits are offered in certain non-U.S. countries and vary by geographic location. The following table presents the funded status of the plans reconciled to the amount reported in the Consolidated Balance Sheets. The measurement date for most of the non-U.S. defined benefit pension and postretirement plans is November 30, consistent with the fiscal year end of the sponsoring companies. For all other plans, measurement occurs as of December 31.

Interest cost for pension and postretirement benefits for our U.S. plans and largest non-U.S. plans is measured using the spot rate approach, which applies specific spot rates along the yield curve to a plan’s corresponding discounted cash flows that comprise the obligation. This method provides a more precise measurement of interest cost by aligning the timing of the plans’ discounted cash flows to the corresponding spot rates on the yield curve . For certain non-U.S. plans, i nterest cost is measured utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligations. A 100 basis point increase in the expected long-term rate of return would decrease the 2021 pension expense by approximately $ 57 million with all other items remaining the same. A 100 basis point increase in the discount rate would increase the 2021 pension expense by approximately $ 1 million. This is because the increase in the interest cost due to the higher discount rate is larger than the decrease in the amortization of the net loss, offset by the decrease in the projected settlement charge of the U.S. qualified plan. Conversely, a 100 basis point decrease in the discount rate would decrease the 2021 pension expense by approximately $ 4 million, while a 100 basis point decrease in the expected long-term rate of return would increase the 2021 pension expense by approximately $ 57 million, with all other items remaining the same. Assumptions The following table summarizes the weighted average assumptions used to determine the benefit obligations: Pension Postretirement U.S. Plans Non-U.S. Plans (a) U.S. Plans Non-U.S. Plans (a) December 31, 2020 Discount rate 2.28 % 1.00 % 2.25 % 2.33 % Interest crediting rate 1.57 % 0.72 % (b) N/A N/A Rate of compensation increase N/A (c) 2.28 % N/A N/A % December 31, 2019 Discount rate 3.16 % 1.09 % 3.14 % 3.18 % Interest crediting rate 2.19 % 0.44 % (b) N/A N/A Rate of compensation increase N/A (c) 2.22 % N/A 3.00 % (a) The non-U.S. plans reflect those assumptions that were most appropriate for the local economic environments of each of the subsidiaries providing such benefits.

The following table summarizes assumed health care cost trend rates for the U.S. plans: At December 31, 2020 2019 Following year: Medical (before age 65) 5.55% 5.74% Medical (age 65 and older) 5.00% 5.00% Ultimate rate to which cost increase is assumed to decline 4.50% 4.50% Year in which the ultimate trend rate is reached: Medical (before age 65) 2038 2038 Medical (age 65 and older) 2038 2038 The following table presents the weighted average assumptions used to determine the net periodic benefit costs: Pension Postretirement U.S. Plans Non-U.S. Plans (a) U.S. Plans Non-U.S. Plans (a) For the Year Ended December 31, 2020 Discount rate 3.16 % 1.09 % 3.14 % 3.18 % Interest crediting rate 2.19 % 0.44 % (b) N/A N/A Rate of compensation increase N/A 2.22 % N/A 3.00 % Expected return on assets 5.55 % 2.32 % N/A N/A For the Year Ended December 31, 2019 Discount rate 4.22 % 1.71 % 4.17 % 4.12 % Interest crediting rate 3.34 % 0.74 % (b) N/A N/A Rate of compensation increase N/A 2.27 % N/A 3.00 % Expected return on assets 6.20 % 2.51 % N/A N/A For the Year Ended December 31, 2018 Discount rate 3.61 % 1.60 % 3.53 % 3.59 % Interest crediting rate 2.88 % 0.70 % (b) N/A N/A Rate of compensation increase N/A 2.27 % N/A 3.00 % Expected return on assets 6.75 % 2.78 % N/A N/A (a) The non-U.S. plans reflect those assumptions that were most appropriate for the local economic environments of each of the subsidiaries providing such benefits. (b) Represents the weighted average interest crediting rate of non-U.S. cash balance plans primarily in Japan and Switzerland. Discount Rate Methodology The projected benefit cash flows under the U.S. AIG Retirement Plan were discounted using the spot rates derived from the Mercer U.S. Pension Discount Yield Curve (Mercer Yield Curve) at December 31, 2020 and 2019, which resulted in a single discount rate that would produce the same liability at the respective measurement dates. The discount rates were 2.28 percent at December 31, 2020 and 3.16 percent at December 31, 2019. The methodology was consistently applied for the respective years in determining the discount rates for the other U.S. pension plans. In general, the discount rates for the non-U.S. plans were developed using a similar methodology to the U.S. AIG Retirement plan, by using country-specific Mercer Yield Curves. The projected benefit obligation for AIG’s Japan pension plans represents approximately 51 percent and 53 percent of the total projected benefit obligations for our non-U.S. pension plans at December 31, 2020 and 2019, respectively. The weighted average discount rate of 0.56 percent and 0.42 percent at December 31, 2020 and 2019, respectively, was selected by reference to the Mercer Yield Curve for Japan. Plan Assets The investment strategy with respect to assets relating to our U.S. and non-U.S. pension plans is designed to achieve investment returns that will provide for the benefit obligations of the plans over the long term, limit the risk of short-term funding shortfalls and maintain liquidity sufficient to address cash needs. Accordingly, the asset allocation strategy is designed to maximize the investment rate of return while managing various risk factors, including, but not limited to, volatility relative to the benefit obligations, liquidity, diversification and concentration, and incorporates the risk/return profile applicable to each asset class. There were no shares of AIG Common Stock included in the U.S. and non-U.S. pension plans assets at December 31, 2020 or 2019. U.S. Pension Plan The assets of the qualified plan are monitored by the AIG U.S. Investment Committee and actively managed by the investment managers, which involves allocating the plan’s assets among approved asset classes within ranges as permitted by the strategic allocation. The long-term strategic asset allocation historically has been reviewed and revised approximately every three years. The investment strategy is focused on de-risking the qualified plan via regular monitoring through liability driven investing and the glide path approach, where the glide path defines the target allocation for the “Return-Seeking” portion of the portfolio (i.e., growth assets) based on the funded ratio and level of interest rates. Under this approach, the allocation to growth assets is reduced and the allocation to liability-hedging assets is increased as the Plan’s funded ratio increases in accordance with the defined glide path. The following table presents the asset allocation percentage by major asset class for the U.S. qualified plan and the target allocation for 2021 based on the plan’s funded status at December 31, 2020: Target Actual Actual At December 31, 2021 2020 2019 Asset class: Equity securities 27 % 25 % 25 % Fixed maturity securities 61 % 57 % 59 % Other investments 12 % 18 % 16 % Total 100 % 100 % 100 % The expected weighted average long-term rate of return for the plan was 5.55 percent and 6.20 percent for 2020 and 2019, respectively. The expected weighted average rate of return is an aggregation of expected returns within each asset class category, weighted for the investment mix of the assets. The combination of the expected asset return and any contributions made by us are expected to maintain the plan’s ability to meet all required benefit obligations. The expected asset return for each asset class was developed based on an approach that considers key fundamental drivers of the asset class returns in addition to historical returns, current market conditions, asset volatility and the expectations for future market returns. Non-U.S. Pension Plans The assets of the non-U.S. pension plans are held in various trusts in multiple countries and are invested primarily in equities and fixed maturity securities to maximize the long-term return on assets for a given level of risk. The following table presents the asset allocation percentage by major asset class for non-U.S. pension plans and the target allocation: Target Actual Actual At December 31, 2021 2020 2019 Asset class: Equity securities 26 % 22 % 23 % Fixed maturity securities 50 % 45 % 43 % Other investments 21 % 24 % 24 % Cash and cash equivalents 3 % 9 % 10 % Total 100 % 100 % 100 % The assets of AIG’s Japan pension plans represent approximately 61 percent of total non-U.S. assets at December 31, 2020 and 2019. The expected long term rate of return was 1.84 percent and 1.82 percent, for 2020 and 2019, respectively, and is evaluated by the Japanese Pension Investment Committee on a quarterly and annual basis along with various investment managers, and is revised to achieve the optimal allocation to meet targeted funding levels if necessary. In addition, the funding policy is revised in accordance with local regulation every five years. The expected weighted average long-term rate of return for all our non-U.S. pension plans was 2.32 percent and 2.51 percent for the years ended December 31, 2020 and 2019, respectively. It is an aggregation of expected returns within each asset class that was generally developed based on the building block approach that considers historical returns, current market conditions, asset volatility and the expectations for future market returns.

Contributed amounts in excess of the minimum amounts are deemed voluntary. Amounts in excess of the maximum amount would be subject to an excise tax and may not be deductible under the Internal Revenue Code. There are no minimum required cash contributions in 2020 for the U.S. AIG Retirement Plan. The non-qualified and postretirement plans’ benefit payments are deductible when paid to participants. Our annual pension contribution in 2021 is expected to be approximately $ 68 million for our U.S. and non-U.S. pension plans. This estimate is subject to change, since contribution decisions are affected by various factors including our liquidity, market performance and management’s discretion. The expected future benefit payments, net of participants’ contributions, with respect to the defined benefit pension plans and other postretirement benefit plans, are as follows: Pension Postretirement U.S. Non-U.S. U.S. Non-U.S. (in millions) Plans Plans Plans Plans 2021 $ 338 $ 44 $ 13 $ 1 2022 334 45 12 2 2023 332 46 12 2 2024 334 53 12 2 2025 317 54 11 2 2026-2030 1,485 298 47 11 Defined Contribution Plans We sponsor several defined contribution plans for U.S. employees that provide for pre-tax salary reduction contributions by employees.

INCOME TAXES	22. Income Taxes U.S. TAX LAW CHANGES On December 22, 2017, the U.S. enacted Public Law 115-97, known informally as the Tax Cuts and Jobs Act (the Tax Act). The Tax Act includes provisions for Global Intangible Low-Taxed Income (GILTI) under which taxes are imposed on the excess of a deemed return on tangible assets of certain foreign subsidiaries and for Base Erosion and Anti-Abuse Tax (BEAT) under which taxes are imposed on certain base eroding payments to affiliated foreign companies. While the U.S. tax authorities issued formal guidance, including recently issued regulations for BEAT and other provisions of the Tax Act, there are still certain aspects of the Tax Act that remain unclear and subject to substantial uncertainties. Additional guidance is expected in future periods. Such guidance may result in changes to the interpretations and assumptions we made and actions we may take, which may impact amounts recorded with respect to international provisions of the Tax Act, possibly materially. Consistent with accounting guidance, we treat BEAT as a period tax charge in the period the tax is incurred and have made an accounting policy election to treat GILTI taxes in a similar manner. On March 27, 2020, the U.S. enacted the Coronavirus Aid, Relief, and Economic Security (CARES) Act to mitigate the economic impacts of the COVID-19 crisis. The tax provisions of the CARES Act have not had and are currently not expected to have a material impact on AIG’s U.S. federal tax liabilities. Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income In February 2018, the FASB issued an accounting standard that allows the optional reclassification of stranded tax effects within AOCI that arise due to the enactment of the Tax Act to retained earnings. We elected to early adopt the standard for the three-month period ended March 31, 2018. As a result of adopting this standard, we reclassified $ 248 million from AOCI to retained earnings. The amount reclassified included stranded effects related to the change in the U.S. federal corporate income tax rate on the gross temporary differences and related valuation allowances. We use an item-by-item approach to release the stranded or disproportionate income tax effects in AOCI related to our available-for-sale securities. Under this approach, a portion of the disproportionate tax effects is assigned to each individual security lot at the date the amount becomes lodged. When the individual securities are sold, mature, or are otherwise impaired on an other-than-temporary basis, the assigned portion of the disproportionate tax effect is reclassified from AOCI to income from continuing operations. EFFECTIVE TAX RATE The following table presents income (loss) from continuing operations before income tax expense (benefit) by U.S. and foreign location in which such pre-tax income (loss) was earned or incurred: Years Ended December 31, (in millions) 2020 2019 2018 U.S. $ ( 8,396) $ 3,825 $ ( 12) Foreign 1,103 1,462 269 Total $ ( 7,293) $ 5,287 $ 257 The following table presents the income tax expense (benefit) attributable to pre-tax income (loss) from continuing operations: Years Ended December 31, (in millions) 2020 2019 2018 Foreign and U.S. components of actual income tax expense (benefit): U.S.: Current $ ( 57) $ 278 $ 134 Deferred ( 1,676) 633 ( 175) Foreign: Current 274 267 202 Deferred ( 1) ( 12) ( 7) Total $ ( 1,460) $ 1,166 $ 154 Our actual income tax expense (benefit) differs from the statutory U.S. federal amount computed by applying the federal income tax rate due to the following: Years Ended December 31, 2020 2019 2018 Pre-Tax Tax Percent of Pre-Tax Tax Percent of Tax Percent of Income Expense/ Pre-Tax Income Expense/ Pre-Tax Pre-Tax Expense/ Pre-Tax (dollars in millions) (Loss) (Benefit) Income (Loss) (Loss) (Benefit) Income (Loss) Income (Benefit) Income U.S. federal income tax at statutory rate $ ( 7,288) $ ( 1,531) 21.0 % $ 5,336 $ 1,120 21.0 % $ 255 $ 54 21.0 % Adjustments: Tax exempt interest ( 19) 0.3 ( 25) ( 0.5) ( 37) ( 14.5) Uncertain tax positions* 165 ( 2.3) 258 4.8 176 69.0 Reclassifications from accumulated other comprehensive income ( 101) 1.4 ( 113) ( 2.1) ( 72) ( 28.2) Dispositions of subsidiaries 180 ( 2.5) 21 0.4 - - Non-controlling interest ( 12) 0.2 ( 5) ( 0.1) ( 1) ( 0.4) Non-deductible transfer pricing charges 11 ( 0.2) 15 0.3 29 11.4 Dividends received deduction ( 39) 0.5 ( 40) ( 0.7) ( 38) ( 14.8) Effect of foreign operations 76 ( 1.0) 82 1.5 65 25.5 Share-based compensation payments excess tax effect 35 ( 0.5) 27 0.5 ( 13) ( 5.1) State income taxes 15 ( 0.2) 13 0.2 10 3.9 Impact of Tax Act - - - - 62 24.3 Expiration of tax attribute carryforwards 221 ( 3.0) - - - - Tax audit resolution ( 379) 5.2 - - - - Other* ( 16) 0.2 ( 134) ( 2.5) ( 102) ( 40.0) Effect of discontinued operations - - ( 8) ( 0.1) 40 15.7 Valuation allowance: Continuing operations ( 65) 0.9 ( 44) ( 0.8) 21 8.2 Consolidated total amounts ( 7,288) ( 1,459) 20.0 5,336 1,167 21.9 255 194 76.0 Amounts attributable to discontinued operations 5 1 20.0 49 1 2.0 ( 2) 40 NM Amounts attributable to continuing operations $ ( 7,293) $ ( 1,460) 20.0 % $ 5,287 $ 1,166 22.1 % $ 257 $ 154 59.9 % * 2020 includes a net charge of $ 67 million related to the accrual of IRS interest, of which $ 139 million tax expense is reported in Uncertain tax positions and $ 72 million tax benefit is reported in Other. 2019 includes a net charge of $ 96 million related to the accrual of IRS interest, of which $ 207 million tax expense is reported in Uncertain tax positions and $( 111) million tax benefit is reported in Other. 2018 includes a net charge of $ 83 million related to the accrual of IRS interest, of which $ 189 million tax expense is reported in Uncertain tax positions and $( 106) million tax expense is reported in Other. For the year ended December 31, 2020, the effective tax rate on loss from continuing operations was 20.0 percent. The effective tax rate on loss from continuing operations differs from the statutory tax rate of 21 percent primarily due to $ 186 million related to tax effects of the Majority Interest Fortitude Sale, tax charge of $ 150 million associated with the establishment of U.S. federal valuation allowance related to certain tax attribute carryforwards, a $ 165 million net charge associated with changes in uncertain tax positions primarily driven by the accrual of IRS interest, $ 76 million associated with the effect of foreign operations, and $ 35 million of excess tax charges related to share-based compensation payments recorded through the income statement. These tax charges were partially offset by tax benefits of $ 379 million associated with the remeasurement of tax liabilities, penalties and interest primarily related to the IRS audit settlement for tax years 1991-2006, $ 101 million of reclassifications from accumulated other comprehensive income to income from continuing operations related to the disposal of available for sale securities, and $ 58 million associated with tax exempt income. We also recognized a $ 221 million tax charge associated with reduction of net operating loss deferred tax assets in certain foreign jurisdictions, with a corresponding decrease in the related deferred tax asset valuation allowance. Effect of foreign operations is primarily related to income and losses in our foreign operations taxed at statutory tax rates different than 21 percent, and foreign income subject to U.S. taxation. As discussed further below, AIG and the IRS entered into a binding settlement agreement related to tax years 1991-2006. The impact of receiving the final settlement agreement resulted in a remeasurement of tax principal, penalties and interest based on agreed upon settlement amounts. For the year ended December 31, 2019, the effective tax rate on income from continuing operations was 22.1 percent. The effective tax rate on income from continuing operations differs from the statutory tax rate of 21 percent primarily due to a $ 96 million net charge principally related to the accrual of IRS interest (including interest related to uncertain tax positions), $ 82 million associated with the effect of foreign operations, $ 37 million of tax charges and related interest associated with increases in uncertain tax positions primarily related to open tax issues and audits in state and local jurisdictions, $ 27 million of excess tax charges related to share-based compensation payments recorded through the income statement, and $ 15 million of non-deductible transfer pricing charges, partially offset by tax benefits of $ 113 million of reclassifications from accumulated other comprehensive income to income from continuing operations related to the disposal of available for sale securities, $ 65 million associated with tax exempt income, and $ 44 million of valuation allowance activity related to certain foreign subsidiaries and state jurisdictions. Effect of foreign operations is primarily related to income and losses in our foreign operations taxed at statutory tax rates different than 21 percent, and foreign income subject to U.S. taxation. For the year ended December 31, 2018, the effective tax rate on income from continuing operations was 59.9 percent. The effective tax rate on income from continuing operations differs from the statutory tax rate of 21 percent primarily due to a $ 83 million net charge primarily related to the accrual of IRS interest (including interest related to uncertain tax positions), $ 62 million measurement period adjustment related to the deemed repatriation tax, $ 65 million associated with the effect of foreign operations, $ 29 million of non-deductible transfer pricing charges, and $ 21 million of valuation allowance activity related to certain foreign subsidiaries and state jurisdictions, partially offset by tax benefits of $ 75 million associated with tax exempt income, and $ 72 million of reclassifications from accumulated other comprehensive income to income from continuing operations related to the disposal of available for sale securities. Effect of foreign operations is primarily related to income and losses in our foreign operations taxed at statutory tax rates different than 21 percent and foreign income subject to U.S. taxation. For the year ended December 31, 2020, we consider earnings of certain operations in Canada, South Africa, the Far East, 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. While, following the enactment of the Tax Act, distributions from foreign affiliates are, generally, not subject to U.S. income tax, such distributions may be subject to non-U.S. withholding taxes. A deferred tax liability of approximately $ 100 million related to such withholding taxes has not been recorded for those foreign subsidiaries whose earnings are considered to be indefinitely reinvested. Additionally, as of December 31, 2020, we do not project any significant potential U.S. tax with respect to foreign currency gains or losses accumulated on previously taxed unremitted foreign earnings and therefore no deferred tax has been recorded. Deferred taxes, if necessary, have been provided on earnings of non-U.S. affiliates whose earnings are not indefinitely reinvested. Given the uncertainties around the impact from the COVID-19 crisis, including the significant global economic slowdown and general market decline, we continue to monitor and review its impact on our reinvestment considerations, including regulatory oversight in the relevant jurisdictions. The following table presents the components of the net deferred tax assets (liabilities): December 31, (in millions) 2020 2019 Deferred tax assets: Losses and tax credit carryforwards $ 9,257 $ 10,541 Basis differences on investments 4,911 2,673 Life policy reserves 2,396 1,766 Accruals not currently deductible, and other 632 743 Investments in foreign subsidiaries 146 148 Loss reserve discount 423 471 Loan loss and other reserves 560 58 Unearned premium reserve reduction 326 382 Fixed assets and intangible assets 1,077 963 Other - 319 Employee benefits 567 617 Total deferred tax assets 20,295 18,681 Deferred tax liabilities: Deferred policy acquisition costs ( 2,026) ( 2,200) Unrealized gains related to available for sale debt securities ( 4,328) ( 2,123) Other ( 221) - Total deferred tax liabilities ( 6,575) ( 4,323) Net deferred tax assets before valuation allowance 13,720 14,358 Valuation allowance ( 1,330) ( 1,427) Net deferred tax assets (liabilities) $ 12,390 $ 12,931 The following table presents our U.S. consolidated income tax group tax losses and credits carryforwards as of December 31, 2020.

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. Our framework for assessing the recoverability of the deferred tax asset requires us to consider all available evidence, including:  the nature, frequency, and amount of cumulative financial reporting income and losses in recent years;  the sustainability of recent operating profitability of our subsidiaries;  the predictability of future operating profitability of the character necessary to realize the net deferred tax asset, including forecasts of future income for each of our businesses and actual and planned business and operational changes;  the carryforward periods for the net operating loss, capital loss and foreign tax credit carryforwards, including the effect of reversing taxable temporary differences; and  prudent and feasible actions and tax planning strategies that would be implemented, if necessary, to protect against the loss of the deferred tax asset. In performing our assessment of the recoverability of the deferred tax asset under this framework, we consider tax laws governing the utilization of the net operating loss, capital loss and foreign tax credit carryforwards in each applicable jurisdiction. Under U.S. tax law, a company generally must use its net operating loss carryforwards before it can use its foreign tax credit carryforwards, even though the carryforward period for the foreign tax credit is shorter than for the net operating loss. Our U.S. federal consolidated income tax group includes both life companies and non-life companies. While the U.S. taxable income of our non-life companies can be offset by our net operating loss carryforwards, only a portion (no more than 35 percent) of the U.S. taxable income of our life companies can be offset by those net operating loss carryforwards. The remaining tax liability of our life companies can be offset by the foreign tax credit carryforwards. Accordingly, we are able to utilize both the net operating loss and foreign tax credit carryforwards concurrently. Recent events, including the COVID-19 crisis, multiple reductions in target interest rates by the Board of Governors of the Federal Reserve System, and significant market volatility, continue 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 macro-economic 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. The carryforward periods of our foreign tax credit carryforwards range from tax years 2021 through 2023. Carryforward periods for our net operating losses extend from 2028 forward. However, utilization of a portion of our net operating losses is limited under separate return limitation year rules. Based on 2020 events and our analysis of their potential impact on utilization of our tax attributes, we concluded that a valuation allowance of $ 150 million should be established on a portion of our foreign tax credit carryforwards that are no longer more-likely-than-not to be realized. Estimates of future taxable income, including income generated from prudent and feasible actions and tax planning strategies, impact of settlements with taxing authorities, and any changes to interpretations and assumptions related to the impact of the Tax Act could change in the near term, perhaps materially, which may require us to consider any potential impact to our assessment of the recoverability of the deferred tax asset. Additionally, estimates of future taxable income, including prudent and feasible tax planning strategies, may be further impacted by market developments arising from the COVID-19 crisis and uncertainty regarding its outcome. Such potential impact could be material to our consolidated financial condition or results of operations for an individual reporting period. For the year ended December 31, 2020, recent changes in market conditions, including the COVID-19 crisis and interest rate fluctuations, impacted the unrealized tax gains and losses in the U.S. Life Insurance companies’ available for sale securities portfolio, resulting in a deferred tax liability related to net unrealized tax capital gains. As of December 31, 2020, based on all available evidence, we concluded that no valuation allowance is necessary in the U.S. Life Insurance companies’ available for sale securities portfolio. For the year ended December 31, 2020, recent changes in market conditions, including interest rate fluctuations, impacted the unrealized tax gains and losses in the U.S. non-life companies’ available for sale securities portfolio, resulting in a deferred tax liability related to net unrealized tax capital gains. As of December 31, 2020, based on all available evidence, we concluded that no valuation allowance is necessary in the U.S. non-life companies’ available for sale securities portfolio. For the year ended December 31, 2020, we recognized a net $ 215 million decrease in deferred tax asset valuation allowance associated with certain foreign jurisdictions, primarily attributable to a corresponding reduction in foreign net operating loss deferred tax assets as a result of restructuring of our European business and the expiration of a portion of net operating losses prior to utilization in Japan. The following table presents the net deferred tax assets (liabilities) at December 31, 2020 and 2019 on a U.S. GAAP basis: December 31, (in millions) 2020 2019 Net U.S. consolidated return group deferred tax assets $ 16,502 $ 14,622 Net deferred tax assets (liabilities) in accumulated other comprehensive income ( 4,259) ( 2,055) Valuation allowance ( 237) ( 90) Subtotal 12,006 12,477 Net foreign, state and local deferred tax assets 1,711 2,006 Valuation allowance ( 1,093) ( 1,337) Subtotal 618 669 Subtotal - Net U.S., foreign, state and local deferred tax assets 12,624 13,146 Net foreign, state and local deferred tax liabilities ( 234) ( 215) Total AIG net deferred tax assets (liabilities) $ 12,390 $ 12,931 Deferred Tax Asset Valuation Allowance of U.S. Consolidated FEDERAL Income Tax Group At December 31, 2020 and 2019, our U.S. consolidated income tax group had net deferred tax assets after valuation allowance of $ 12.0 billion and 12.5 billion, respectively. At December 31, 2020 and 2019, our U.S. consolidated income tax group had valuation allowances of $ 237 million and $ 90 million, respectively. Deferred Tax ASSET – Foreign, State and Local At December 31, 2020 and 2019, we had net deferred tax assets (liabilities) of $ 384 million and $ 454 million, respectively, related to foreign subsidiaries, state and local tax jurisdictions, and certain domestic subsidiaries that file separate tax returns. At December 31, 2020 and 2019, we had deferred tax asset valuation allowances of $ 1.1 billion and $ 1.3 billion, respectively, related to foreign subsidiaries, state and local tax jurisdictions, and certain domestic subsidiaries that file separate tax returns. We maintained these valuation allowances following our conclusion that we could not demonstrate that it was more likely than not that the related deferred tax assets will be realized. This was primarily due to factors such as cumulative losses in recent years and the inability to demonstrate profits within the specific jurisdictions over the relevant carryforward periods. Tax Examinations and Litigation We file a consolidated U.S. federal income tax return with our eligible U.S. subsidiaries. Income earned by subsidiaries operating outside the U.S. is taxed, and income tax expense is recorded, based on applicable U.S. and foreign law. We are currently under examination for the tax years 2007 through 2013. On August 1, 2012, we filed a motion for partial summary judgment related to the disallowance of foreign tax credits associated with cross border financing transactions in the Southern District of New York (SDNY). The SDNY denied our summary judgment motion and upon AIG’s appeal, the U.S. Court of Appeals for the Second Circuit (the Second Circuit) affirmed the denial. AIG’s petition for certiorari to the U.S. Supreme Court from the decision of the Second Circuit was denied on March 7, 2016. As a result, the case was remanded back to the SDNY for a jury trial. In January 2018, the parties reached non-binding agreements in principle on issues presented in the dispute. In 2019, we agreed with the IRS to execute an agreement for the tax years at issue in which AIG would waive restrictions on the assessment of additional tax related to the settlement of the underlying issues in those tax years. The litigation was stayed pending the outcome of the review process. During the fourth quarter of 2020, the parties concluded the review process and executed a binding settlement agreement on the underlying issues in those tax years. On October 22, 2020, the Southern District dismissed the case based upon the settlement reached between AIG and the government. The parties continue to review the related interest calculations based on the settlement agreement, which will become due upon the IRS’ issuance of a Notice and Demand for Payment. In September 2020, we received the IRS Revenue Agent Report containing agreed and disagreed issues for the audit of tax years 2007-2010. In October 2020, we filed a protest of the disagreed issues with IRS Appeals. Accounting For Uncertainty in Income Taxes The following table presents a reconciliation of the beginning and ending balances of the total amounts of gross unrecognized tax benefits: Years Ended December 31, (in millions) 2020 2019 2018 Gross unrecognized tax benefits, beginning of year $ 4,762 $ 4,709 $ 4,707 Increases in tax positions for prior years 45 51 14 Decreases in tax positions for prior years ( 131) ( 1) ( 6) Increases in tax positions for current year 13 4 - Settlements ( 2,346) ( 1) ( 6) Gross unrecognized tax benefits, end of year $ 2,343 $ 4,762 $ 4,709 At December 31, 2020, 2019 and 2018, our unrecognized tax benefits, excluding interest and penalties, were $ 2.3 billion, $ 4.8 billion and $ 4.7 billion, respectively. The activity for the year ended December 31, 2020 includes the impact of the binding settlement agreement with the IRS for tax years 1991-2006 with respect to cross border financing transactions. After remeasurement based on the settlement terms, the remaining balances of the unrecognized tax benefits, penalties and interest related to the 1991-2006 tax years are no longer presented as uncertain tax positions and were reclassified as prior year current tax payable. The activity for the year ended December 31, 2019 includes increases primarily related to open tax issues and audits in state and local jurisdictions. The activity for the year ended 2018 is not material. At December 31, 2020, 2019 and 2018, our unrecognized tax benefits related to tax positions that, if recognized, would not affect the effective tax rate because they relate to such factors as the timing, rather than the permissibility, of the deduction were $ 44 million, $ 43 million and $ 38 million, respectively. Accordingly, at December 31, 2020, 2019 and 2018, the amounts of unrecognized tax benefits that, if recognized, would favorably affect the effective tax rate were $ 2.3 billion, $ 4.7 billion and $ 4.7 billion, respectively. Interest and penalties related to unrecognized tax benefits are recognized in income tax expense. At December 31, 2020, 2019, and 2018, we had accrued liabilities of $ 286 million, $ 2.4 billion, and $ 2.2 billion, respectively, for the payment of interest (net of the federal benefit) and penalties. For the years ended December 31, 2020, 2019, and 2018, we accrued expense of $ 128 million, $ 236 million and $ 190 million, respectively, for the payment of interest and penalties. The activity in the fourth quarter of 2020 also includes a net decrease of $ 2.2 billion, which is attributable to decreases and settlements of interest and penalties associated with the completion of the IRS examination for tax years 1991-2006. During the fourth quarter of 2020, interest accrued was re-computed factoring in principal tax and penalty adjustments based on the final IRS settlement agreement, including estimated impact of interest netting which we have already formally requested. We believe it is reasonably possible that our unrecognized tax benefits could decrease within the next 12 months by as much as $ 1.2 billion, principally as a result of potential resolutions or settlements of prior years’ tax items. The prior years’ tax items include unrecognized tax benefits related to the deductibility of certain expenses. Listed below are the tax years that remain subject to examination by major tax jurisdictions: At December 31, 2020 Open Tax Years Major Tax Jurisdiction United States 2007- 2019 Australia 2016- 2019 Canada 2013- 2019 France 2018- 2019 Japan 2014- 2019 Korea 2015- 2019 Singapore 2016- 2019 United Kingdom 2019- 2019

BASIS OF PRESENTATION
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:  liability for unpaid losses and loss adjustment expenses (loss reserves);  valuation of future policy benefit liabilities and timing and extent of loss recognition;  valuation of liabilities for guaranteed benefit features of variable annuity products;  valuation of embedded derivatives for fixed index annuity and life products;  estimated gross profits to value deferred policy acquisition costs for investment-oriented products;  reinsurance assets, including the allowance for credit losses;  goodwill impairment;  allowances for credit losses primarily on loans and available for sale fixed maturity securities;  liability for legal contingencies;  fair value measurements of certain financial assets and liabilities; and  income tax assets and liabilities, including recoverability of our net deferred tax asset and the predictability of future tax operating profitability of the character necessary to realize the net deferred tax asset and estimates associated with the Tax Cuts and Jobs Act (the Tax Act). 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.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2020
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Investments	Short-term investments Short-term investments include highly liquid securities and other investments with remaining maturities of one year or less, but greater than three months, at the time of purchase. Securities included within short-term investments are stated at estimated fair value, while other investments included within short-term investments are stated at amortized cost, which approximates estimated fair value. Fixed Maturity Securities Subsequent to the adoption of the Financial Instruments Credit Losses Standard on January 1, 2020 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 are measured at fair value at our election. None of our fixed maturity securities met the criteria for held to maturity classification at December 31, 2020 or 2019. 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 policy related amounts and deferred income taxes, in shareholders’ equity. Realized and unrealized gains and losses from fixed maturity securities measured at fair value at our election 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 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. Prior to the adoption of the Financial Instruments Credit Losses Standard on January 1, 2020 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 RMBS, CMBS and CDO/ABS, (collectively, 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, effective yields are recalculated and adjusted prospectively based on changes in expected undiscounted future cash flows. For purchased credit impaired (PCI) securities, at acquisition, the difference between the undiscounted expected future cash flows and the recorded investment in the securities represents the initial accretable yield, which is to be accreted into net investment income over the securities’ remaining lives on an effective level-yield basis. Subsequently, effective yields recognized on PCI securities are recalculated and adjusted prospectively to reflect changes in the contractual benchmark interest rates on variable rate securities and any significant increases in undiscounted expected future cash flows arising due to reasons other than interest rate changes. 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, affordable housing partnerships 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 Net investment income represents income primarily from the following sources:  Interest income and related expenses, including amortization of premiums and accretion of discounts with changes in the timing and the amount of expected principal and interest cash flows reflected in yield, as applicable.  Dividend income from common and preferred stocks.  Realized and unrealized gains and losses from investments in other securities and investments for which we elected the fair value option.  Earnings from alternative investments.  Prepayment premiums. The following table presents the components of Net investment income: Net Realized Capital Gains and Losses Net realized capital gains and losses are determined by specific identification. The net realized capital 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.  Changes in fair value of free standing and embedded derivatives, including changes in the non-performance adjustment, except for those instruments that are designated as hedging instruments when the change in the fair value of the hedged item is not reported in Net realized capital 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/OTHER-than-TEMPORARY IMPAIRMENTS Fixed Maturity Securities Subsequent to the adoption of the Financial Instruments Credit Losses Standard on January 1, 2020 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 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 realized capital 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 realized capital 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 accumulated other comprehensive income). 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, CDO, 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. Credit losses are reassessed each period. The allowance for credit losses and the corresponding charge to realized capital 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 decreasing realized capital losses. Prior to the adoption of the Financial Instruments Credit Losses Standard on January 1, 2020 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 the fair value of the security is below amortized cost, an other-than-temporary impairment has occurred and the amortized cost is written down to current fair value, with a corresponding charge to realized capital losses. 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 credit impairment has occurred, the amortized cost is written down to the estimated recoverable value with a corresponding charge to realized capital losses. 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 related to a credit impairment is presented in unrealized appreciation (depreciation) of fixed maturity securities on which other-than-temporary credit impairments were recognized (a separate component of accumulated other comprehensive income). 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. In periods subsequent to the recognition of an other-than-temporary impairment charge for available for sale fixed maturity securities that is not foreign exchange related, we prospectively accrete into earnings the difference between the new amortized cost and the expected undiscounted recoverable value over the remaining expected holding period of the security. 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 aircraft assets and 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. We sold the remaining portion of our aircraft assets in 2018. Purchased Credit Deteriorated/Impaired Securities Subsequent to the adoption of the Financial Instruments Credit Losses Standard on January 1, 2020 We purchase certain RMBS securities that have experienced more-than-insignificant deterioration in credit quality since origination. Subsequent to the adoption of the Financial Instruments Credit Losses Standard 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. During the twelve-month period ended December 31, 2020, we purchased certain securities which had more than insignificant credit deterioration since their origination. These PCD securities are held in the portfolio of bonds available for sale in their natural classes at December 31, 2020. Prior to the adoption of the Financial Instruments Credit Losses Standard on January 1, 2020 We purchase certain RMBS securities that have experienced deterioration in credit quality since their issuance. We determine whether it is probable at acquisition that we will not collect all contractually required payments for these PCI securities, including both principal and interest. At acquisition, the timing and amount of the undiscounted future cash flows expected to be received on each PCI security is determined based on our best estimate using key assumptions, such as interest rates, default rates and prepayment speeds. At acquisition, the difference between the undiscounted expected future cash flows of the PCI securities and the recorded investment in the securities represents the initial accretable yield, which is accreted into Net investment income over their remaining lives on an effective yield basis. Additionally, the difference between the contractually required payments on the PCI securities and the undiscounted expected future cash flows represents the non-accretable difference at acquisition. The accretable yield and the non-accretable difference will change over time, based on actual payments received and changes in estimates of undiscounted expected future cash flows, which are discussed further below. On a quarterly basis, the undiscounted expected future cash flows associated with PCI securities are re-evaluated based on updates to key assumptions. Declines in undiscounted expected future cash flows due to further credit deterioration as well as changes in the expected timing of the cash flows can result in the recognition of an other-than-temporary impairment charge, as PCI securities are subject to our policy for evaluating investments for other-than-temporary impairment. Changes to undiscounted expected future cash flows due solely to the changes in the contractual benchmark interest rates on variable rate PCI securities will change the accretable yield prospectively. Significant increases in undiscounted expected future cash flows for reasons other than interest rate changes are recognized prospectively as adjustments to the accretable yield. 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. Mortgage and other loans receivable include commercial mortgages, residential mortgages, life insurance policy loans, commercial loans, and other loans and notes receivable. Commercial mortgages, residential 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. Premiums and discounts on purchased residential mortgages are also 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. Interest income is not accrued when payment of contractual principal and interest is not expected. Any cash received on impaired loans is generally recorded as a reduction of the current carrying amount of the loan. Accrual of interest income is generally resumed when delinquent contractual principal and interest is repaid or when a portion of the delinquent contractual payments are made and the ongoing required contractual payments have been made for an appropriate period. As of December 31, 2020, $ 14 million and $ 238 million of residential mortgage loans and commercial mortgage loans, respectively, were placed on nonaccrual status. Accrued interest is presented separately and is included in Other assets 14 million and $ 129 million associated with residential mortgage loans and commercial mortgage loans, respectively. A significant majority of commercial mortgages in the portfolio are non-recourse loans and, accordingly, the only guarantees are for specific items that are exceptions to the non-recourse provisions. It is therefore extremely rare for us to have cause to enforce the provisions of a guarantee on a commercial real estate or mortgage loan. Methodology Used to Estimate the Allowance for Credit Losses Subsequent to the adoption of the Financial Instruments Credit Losses Standard on January 1, 2020 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 capital losses. This allowance reflects the risk of loss, even when that risk is remote, and reflects losses 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 and residential 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, FICO 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 capital gains (losses) in the Consolidated Statements of Income. Prior to the adoption of the Financial Instruments Credit Losses Standard on January 1, 2020 Mortgage and other loans receivable are considered impaired when collection of all amounts due under contractual terms is not probable. Impairment is measured using either i) the present value of expected future cash flows discounted at the loan’s effective interest rate, ii) the loan’s observable market price, if available, or iii) the fair value of the collateral if the loan is collateral dependent. Impairment of commercial mortgages is typically determined using the fair value of collateral while impairment of other loans is typically determined using the present value of cash flows or the loan’s observable market price. An allowance is typically established for the difference between the impaired value of the loan and its current carrying amount. Additional allowance amounts are established for incurred but not specifically identified impairments, based on statistical models primarily driven by past-due status, debt service coverage, loan-to-value ratio, property type and location, loan term, profile of the borrower and of the major property tenants, and loan seasoning. When all or a portion of a loan is deemed uncollectable, the uncollectable portion of the carrying amount of the loan is charged off against the allowance.
Reinsurance	In the ordinary course of business, our insurance companies may use both treaty and facultative reinsurance to minimize their net loss exposure to any single catastrophic loss event or to an accumulation of losses from a number of smaller events or to provide greater diversification of our businesses. In addition, our General Insurance subsidiaries assume reinsurance from other insurance companies. We determine the portion of the incurred but not reported (IBNR) loss that will be recoverable under our reinsurance contracts by reference to the terms of the reinsurance protection purchased. This determination is necessarily based on the estimate of IBNR and accordingly, is subject to the same uncertainties as the estimate of IBNR. Reinsurance assets include the balances due from reinsurance and insurance companies under the terms of our reinsurance agreements for paid and unpaid losses and loss adjustment expenses incurred, 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 unpaid losses and benefits and loss expenses with respect to these reinsurance agreements are substantially collateralized. We remain liable to the extent that our reinsurers do not meet their obligation 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 credit losses and disputes requires judgment for which key inputs typically include historical trends regarding uncollectible balances, disputes and credit events 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 $ 326 million and $ 151 million at December 31, 2020 and 2019, respectively. Changes in the allowance for credit losses and disputes on reinsurance assets are reflected in Policyholder benefits and losses incurred within the Consolidated Statements of Income. 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 $ 18.9 billion and $ 13.9 billion, and the deferred gain liability was $ 1.7 billion and $ 1.8 billion, as of December 31, 2020 and 2019, respectively. The effect on income from amortization of the deferred gain was $ 237 million, $ 219 million and $ 394 million for the years ended December 31, 2020, 2019 and 2018, respectively. Long-Duration Reinsurance Long-duration reinsurance is effected principally under yearly renewable term (YRT) treaties, along with a large modco treaty with a former affiliate, Fortitude Re, that was deconsolidated following the Majority Interest Fortitude Sale. This modco treaty reinsures the majority of our long-duration run-off business. The premiums with respect to YRT treaties are earned over the contract period in proportion to the protection provided, while ceded premiums related to modco treaties are recognized when due. Amounts recoverable on YRT treaties are recognized when claims are incurred on the reinsured policies and are presented as a component of reinsurance assets. Amounts recoverable on the modco treaty are estimated in a manner consistent with the assumptions used for the underlying policy benefits and are presented as a separate reinsurance asset. Sale of Fortitude Holdings On June 2, 2020, we completed the Majority Interest Fortitude Sale. AIG established Fortitude Re, a wholly-owned subsidiary of Fortitude Holdings, in 2018 in a series of reinsurance transactions related to AIG’s Run-Off operations. As of December 31, 2020, approximately $ 30.5 billion of reserves from AIG’s Life and Retirement Run-Off Lines and approximately $ 4.1 billion of reserves from AIG’s General Insurance Run-Off Lines, related to business written by multiple wholly-owned AIG subsidiaries, had been ceded to Fortitude Re under these reinsurance transactions. As of closing of the Majority Interest Fortitude Sale, these reinsurance transactions are no longer considered affiliated transactions and Fortitude Re is the reinsurer of the majority of AIG’s Run-Off operations. These reinsurance transactions between AIG and Fortitude Re were 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 other comprehensive income). As a result of the deconsolidation resulting from the Majority Interest Fortitude Sale, 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 capital 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.

(b) The derivative assets have been presented net of collateral. The derivative assets supporting the Fortitude Re funds withheld arrangements had a fair market value of $ 357 million as of December 31, 2020. These derivative assets are fully collateralized. (c) Primarily comprised of Cash and Accrued investment income. The impact of the funds withheld arrangements with Fortitude Re for the period post June 2, 2020 deconsolidation was as follows: Twelve Months Ended (in millions) December 31, 2020 Net underwriting income $ - Net investment income - Fortitude Re funds withheld assets 1,053 Net realized capital losses on Fortitude Re funds withheld assets: Net realized capital gains - Fortitude Re funds withheld assets 463 Net realized capital losses - Fortitude Re embedded derivatives ( 2,645) Net realized capital losses on Fortitude Re funds withheld assets ( 2,182) Loss from continuing operations before income tax benefit ( 1,129) Income tax benefit (a) ( 237) Net loss ( 892) Change in unrealized appreciation of all other investments (a) 812 Comprehensive loss $ ( 80) (a) The income tax expense (benefit) and the tax impact in accumulated other comprehensive income was computed using AIG’s U.S. statutory tax rate of 21 percent. Various assets supporting the Fortitude Re funds withheld arrangements are reported at amortized cost, and as such, changes in the fair value of these assets are not reflected in the financial statements. However, changes in the fair value of these assets are included in the embedded derivative in the Fortitude Re funds withheld arrangement and the appreciation of these assets is the primary driver of the comprehensive loss reflected above. 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. Reinsurance assets include reinsurance recoverables on unpaid losses and loss adjustment expenses that are estimated as part of our loss reserving process and, consequently, are subject to similar judgments and uncertainties as the estimation of gross loss reserves. Similarly, Other assets include reinsurance recoverables for contracts which are accounted for as deposits. 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 uncollectable reinsurance that reduces the carrying amount of reinsurance and other assets on the consolidated balance sheets (collectively, the reinsurance recoverable balances). 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 determined by the Obligor Risk Ratings (ORRs) we assign to each reinsurer based upon our financial reviews; insurers 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 rating. The allowance for credit losses excludes disputed amounts. An allowance for disputes is established for a reinsurance recoverable using the losses incurred model for contingencies. The total reinsurance recoverables as of December 31, 2020 were $ 75.8 billion. As of that date, utilizing AIG’s ORRs, (i) approximately 92 percent of the reinsurance recoverables were investment grade, of which 52 percent related to General Insurance and 40 percent related to Life and Retirement; (ii) approximately 7 percent of the reinsurance recoverables were non-investment grade, the majority of which related to General Insurance; (iii) less than one one As of December 31, 2020, approximately 64 percent of our non-investment grade reinsurance exposure related to captive insurers. These arrangements are typically collateralized by letters of credit, funds withheld or trust agreements.
Variable Interest Entity	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.
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 deferred policy acquisition costs 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. 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. Short-duration insurance contracts: 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. Long-duration insurance contracts: Policy acquisition costs for participating life, traditional life and accident and health insurance products are generally deferred and amortized, with interest, over the premium paying period. The assumptions used to calculate the benefit liabilities and DAC for these traditional products are set when a policy is issued and do not change with changes in actual experience, unless a loss recognition event occurs. These “locked-in” assumptions include mortality, morbidity, persistency, maintenance expenses and investment returns, and include margins for adverse deviation to reflect uncertainty given that actual experience might deviate from these assumptions. A loss recognition event occurs when there is a shortfall between the carrying amount of future policy benefit liabilities, net of DAC, and what the future policy benefit liabilities, net of DAC, would be when applying updated current assumptions. When we determine a loss recognition event has occurred, we first reduce any DAC related to that block of business through amortization of acquisition expense, and after DAC is depleted, we record additional liabilities through a charge to Policyholder benefits and losses incurred. Groupings for loss recognition testing are consistent with our manner of acquiring, servicing and measuring the profitability of the business and applied by product groupings. We perform separate loss recognition tests for traditional life products, payout annuities and long-term care products. Once loss recognition has been recorded for a block of business, the old assumption set is replaced and the assumption set used for the loss recognition would then be subject to the lock-in principle. Investment-oriented contracts: Certain policy acquisition costs and policy issuance costs related to universal life and investment-type products (collectively, investment-oriented products) are deferred and amortized, with interest, in relation to the incidence of estimated gross profits to be realized over the estimated lives of the contracts. DAC on investment-oriented contracts were approximately $ 5.1 billion and $ 6.1 billion at December 31, 2020 and 2019, respectively. Estimated gross profits are affected by a number of factors, including levels of current and expected interest rates, net investment income and spreads, net realized capital gains and losses, fees, surrender rates, mortality experience, policyholder behavior experience and equity market returns and volatility. In each reporting period, current period amortization expense is adjusted to reflect actual gross profits. If the assumptions used for estimating gross profit change significantly, DAC is recalculated using the new assumptions, including actuarial assumptions such as mortality, lapse, benefit utilization, and premium persistency, and any resulting adjustment is included in income. If the new assumptions indicate that future estimated gross profits are higher than previously estimated, DAC will be increased resulting in a decrease in amortization expense and increase in income in the current period; if future estimated gross profits are lower than previously estimated, DAC will be decreased resulting in an increase in amortization expense and decrease in income in the current period. Updating such assumptions may result in acceleration of amortization in some products and deceleration of amortization in other products. 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 current and projected future profitability of the underlying insurance contracts. To estimate future estimated gross profits for variable annuity products, a long-term annual asset growth assumption is applied to determine the future growth in assets and related asset-based fees. In determining the asset growth rate, the effect of short-term fluctuations in the equity markets is partially mitigated through the use of a “reversion to the mean” methodology whereby short-term asset growth above or below long-term annual rate assumptions impacts the growth assumption applied to the five-year period subsequent to the current balance sheet date. The reversion to the mean methodology allows us to maintain our long-term growth assumptions, while also giving consideration to the effect of actual investment performance. When actual performance significantly deviates from the annual long-term growth assumption, as evidenced by growth assumptions in the five-year reversion to the mean period falling below a certain rate (floor) or rising above a certain rate (cap) for a sustained period, judgment may be applied to revise or “unlock” the growth rate assumptions to be used for both the five-year reversion to the mean period as well as the long-term annual growth assumption applied to subsequent periods. Shadow DAC and Shadow Loss Recognition: DAC related to investment-oriented products is also adjusted to reflect the effect of unrealized gains or losses on fixed maturity securities available for sale, with related changes recognized through Other comprehensive income (shadow DAC). The adjustment is made at each balance sheet date, as if the securities had been sold at their stated aggregate fair value and the proceeds reinvested at current yields. Similarly, for long-duration traditional insurance contracts, if the assets supporting the liabilities are in a net unrealized gain position at the balance sheet date, loss recognition testing assumptions are updated to exclude such gains from future cash flows by reflecting the impact of reinvestment rates on future yields. If a future loss is anticipated under this basis, any additional shortfall indicated by loss recognition tests is recognized as a reduction in accumulated other comprehensive income (shadow loss recognition). Similar to other loss recognition on long-duration insurance contracts, such shortfall is first reflected as a reduction in DAC and secondly as an increase in liabilities for future policy benefits. The change in these adjustments, net of tax, is included with the change in net unrealized appreciation of investments that is credited or charged directly to Other comprehensive income. Internal Replacements of Long-duration and Investment-oriented Products: For some products, policyholders can elect to modify product benefits, features, rights or coverages by exchanging a contract for a new contract or by amendment, endorsement, or rider to a contract, or by the election of a feature or coverage within a contract. These transactions are known as internal replacements. If the modification does not substantially change the contract, we do not change the accounting and amortization of existing DAC and related actuarial balances. If an internal replacement represents a substantial change, the original contract is considered to be extinguished and any related DAC or other policy balances are charged or credited to income, and any new deferrable costs associated with the replacement contract are deferred. Value of Business Acquired (VOBA) is determined at the time of acquisition and is reported in the Consolidated Balance Sheets with DAC. This value is based on the present value of future pre-tax profits discounted at yields applicable at the time of purchase. For participating life, traditional life and accident and health insurance products, VOBA is amortized over the life of the business in a manner similar to that for DAC based on the assumptions at purchase. For investment-oriented products, VOBA is amortized in relation to estimated gross profits and adjusted for the effect of unrealized gains or losses on fixed maturity securities available for sale and prior to 2018, equity securities at fair value in a manner similar to DAC.
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 mitigate financial risk embedded in certain insurance liabilities and economically hedge certain investments. 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 instruments 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. Interest rate, currency, equity and commodity swaps, credit contracts, swaptions, options and forward transactions are accounted for as derivatives, recorded on a trade-date basis and carried at fair value. Unrealized gains and losses are reflected in income, when appropriate. Aggregate asset or liability positions are netted on the Consolidated Balance Sheets only to the extent permitted by qualifying master netting arrangements in place with each respective counterparty. Cash collateral posted with counterparties in conjunction with transactions supported by qualifying master netting arrangements is reported as a reduction of the corresponding net derivative liability, while cash collateral received in conjunction with transactions supported by qualifying master netting arrangements is reported as a reduction of the corresponding net derivative asset. Derivatives, with the exception of embedded derivatives, are reported at fair value in the Consolidated Balance Sheets in Other assets and Other liabilities. Embedded derivatives are generally presented with the host contract in the Consolidated Balance Sheets. A bifurcated embedded derivative is measured at fair value and accounted for in the same manner as a free standing derivative contract. The corresponding host contract is accounted for according to the accounting guidance applicable for that instrument. For additional information on embedded derivatives see Notes 5 and 14.
Liability for unpaid claims and claims adjustment expense	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. Given the uncertainties around the impact from the COVID-19 crisis, including the significant global economic slowdown and general market decline, the full impact of COVID-19 and how it may ultimately impact the results of our insurance operations remains uncertain. In addition, in response to the crisis, new governmental, legislative and regulatory initiatives have been put in place and continue to be developed that could result in additional restrictions and requirements relating to our policies that may have a negative impact on our business operations. However, we have recorded our estimate of the ultimate liability for claims that have occurred as of the balance sheet date associated with COVID-19 which reflects our expectations given the current facts and circumstances. We will continue to monitor and review the impact. 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.
Future policy benefits for life and accident and health insurance contracts and policyholder contract deposits	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. Included in Future policy benefits are liabilities for annuities issued in structured settlement arrangements whereby a claimant has agreed to settle a general insurance claim in exchange for fixed payments over a fixed determinable period of time with a life contingency feature. In addition, reserves for contracts in loss recognition are adjusted to reflect the effect of unrealized gains on fixed maturity securities available for sale. Future policy benefits also include certain guaranteed benefits of variable annuity products that are not considered embedded derivatives, primarily guaranteed minimum death benefits. For additional information on guaranteed minimum death benefits see Note 14. The liability for long-duration future policy benefits has been established including assumptions for interest rates which vary by year of issuance and product, and range from approximately 0.1 percent to 14.6 percent. Mortality and surrender rate assumptions are generally based on actual experience when the liability is established. Policyholder Contract Deposits The liability for Policyholder contract deposits is primarily recorded at accumulated value (deposits received and net transfers from separate accounts, plus accrued interest credited at rates ranging from 0 percent to 9.0 percent at December 31, 2020, less withdrawals and assessed fees). Deposits collected on investment-oriented products are not reflected as revenues, because they are recorded directly to Policyholder contract deposits upon receipt. Amounts assessed against the contract holders for mortality, administrative, and other services are included in revenues. In addition to liabilities for universal life, fixed annuities, fixed options within variable annuities, annuities without life contingencies, funding agreements and GICs, policyholder contract deposits also include our liability for (i) certain guaranteed benefits and indexed features accounted for as embedded derivatives at fair value, (ii) annuities issued in a structured settlement arrangement with no life contingency and (iii) certain contracts we have elected to account for at fair value. For additional information on guaranteed benefits accounted for as embedded derivatives see Note 14. For universal life policies with secondary guarantees, we recognize certain liabilities in addition to policyholder account balances. For universal life policies with secondary guarantees, as well as other universal life policies for which profits followed by losses are expected at contract inception, a liability is recognized based on a benefit ratio of (a) the present value of total expected payments, in excess of the account value, over the life of the contract, divided by (b) the present value of total expected assessments over the life of the contract. For universal life policies without secondary guarantees, for which profits followed by losses are first expected after contract inception, we establish a liability, in addition to policyholder account balances, so that expected future losses are recognized in proportion to the emergence of profits in the earlier (profitable) years. Universal life account balances as well as these additional liabilities related to universal life products are reported within Policyholder contract deposits in the Consolidated Balance Sheet. These additional liabilities are also adjusted to reflect the effect of unrealized gains or losses on fixed maturity securities available for sale and prior to 2018, equity securities at fair value on accumulated assessments, with related changes recognized through Other comprehensive income. The policyholder behavior assumptions for these liabilities include mortality, lapses and premium persistency. The capital market assumptions used for the liability for universal life secondary guarantees include discount rates and net earned rates. Other Policyholder Funds Other policyholder funds include unearned revenue reserves (URR). URR consist of front-end loads on investment-oriented contracts, representing those policy loads that are non-level and typically higher in initial policy years than in later policy years. URR for investment-oriented contracts are generally deferred and amortized, with interest, in relation to the incidence of estimated gross profits (EGPs) to be realized over the estimated lives of the contracts and are subject to the same adjustments due to changes in the assumptions underlying EGPs as DAC. Amortization of URR is recorded in Policy fees. Similar to shadow DAC, URR related to investment-oriented products is also adjusted to reflect the effect of unrealized gains or losses on fixed maturity securities available for sale and also, prior to 2018, equity securities at fair value on estimated gross profits, with related changes recognized through Other comprehensive income (shadow URR). Other policyholder funds also include provisions for future dividends to participating policyholders, accrued in accordance with all applicable regulatory or contractual provisions. Participating life business represented approximately 1.4 percent of gross insurance in force at December 31, 2020 and 1.9 percent of gross domestic premiums and other considerations in 2020. The amount of annual dividends to be paid is approved locally by the boards of directors of the Life and Retirement companies. Provisions for future dividend payments are computed by jurisdiction, reflecting local regulations. The portions of current and prior net income and of current unrealized appreciation of investments that can inure to our benefit are restricted in some cases by the insurance contracts and by the local insurance regulations of the jurisdictions in which the policies are in force. Certain products are subject to experience adjustments. These include group life and group medical products, credit life contracts, accident and health insurance contracts/riders attached to life policies and, to a limited extent, reinsurance agreements with other direct insurers. Ultimate premiums from these contracts are estimated and recognized as revenue with the unearned portions of the premiums recorded as liabilities in Other policyholder funds. Experience adjustments vary according to the type of contract and the territory in which the policy is in force and are subject to local regulatory guidance.
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.
Noncontrolling Interests	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.
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.
Income Taxes	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. Our framework for assessing the recoverability of the deferred tax asset requires us to consider all available evidence, including:  the nature, frequency, and amount of cumulative financial reporting income and losses in recent years;  the sustainability of recent operating profitability of our subsidiaries;  the predictability of future operating profitability of the character necessary to realize the net deferred tax asset, including forecasts of future income for each of our businesses and actual and planned business and operational changes;  the carryforward periods for the net operating loss, capital loss and foreign tax credit carryforwards, including the effect of reversing taxable temporary differences; and  prudent and feasible actions and tax planning strategies that would be implemented, if necessary, to protect against the loss of the deferred tax asset. In performing our assessment of the recoverability of the deferred tax asset under this framework, we consider tax laws governing the utilization of the net operating loss, capital loss and foreign tax credit carryforwards in each applicable jurisdiction. Under U.S. tax law, a company generally must use its net operating loss carryforwards before it can use its foreign tax credit carryforwards, even though the carryforward period for the foreign tax credit is shorter than for the net operating loss. Our U.S. federal consolidated income tax group includes both life companies and non-life companies. While the U.S. taxable income of our non-life companies can be offset by our net operating loss carryforwards, only a portion (no more than 35 percent) of the U.S. taxable income of our life companies can be offset by those net operating loss carryforwards. The remaining tax liability of our life companies can be offset by the foreign tax credit carryforwards. Accordingly, we are able to utilize both the net operating loss and foreign tax credit carryforwards concurrently. Recent events, including the COVID-19 crisis, multiple reductions in target interest rates by the Board of Governors of the Federal Reserve System, and significant market volatility, continue 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 macro-economic 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. The carryforward periods of our foreign tax credit carryforwards range from tax years 2021 through 2023. Carryforward periods for our net operating losses extend from 2028 forward. However, utilization of a portion of our net operating losses is limited under separate return limitation year rules. Based on 2020 events and our analysis of their potential impact on utilization of our tax attributes, we concluded that a valuation allowance of $ 150 million should be established on a portion of our foreign tax credit carryforwards that are no longer more-likely-than-not to be realized. Estimates of future taxable income, including income generated from prudent and feasible actions and tax planning strategies, impact of settlements with taxing authorities, and any changes to interpretations and assumptions related to the impact of the Tax Act could change in the near term, perhaps materially, which may require us to consider any potential impact to our assessment of the recoverability of the deferred tax asset. Additionally, estimates of future taxable income, including prudent and feasible tax planning strategies, may be further impacted by market developments arising from the COVID-19 crisis and uncertainty regarding its outcome. Such potential impact could be material to our consolidated financial condition or results of operations for an individual reporting period.
Revenues and expenses	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. Reinsurance premiums ceded under prospective reinsurance agreements are recognized as a reduction in revenues over the period the reinsurance coverage is provided in proportion to the risks to which the premiums relate. Reinsurance premiums for assumed business are estimated based on information received from brokers, ceding companies and reinsureds. Any subsequent differences that arise regarding such estimates are recorded in the periods in which they are determined. Premiums for long-duration insurance products and life contingent annuities are recognized as revenues when due. Estimates for premiums due but not yet collected are accrued. Policy fees represent fees recognized from universal life and investment-type products consisting of policy charges for the cost of insurance, policy administration charges, surrender charges and amortization of unearned revenue reserves. Policy fees are recognized as revenues in the period in which they are assessed against policyholders, unless the fees are designed to compensate AIG for services to be provided in the future. Fees deferred as unearned revenue are amortized in relation to the incidence of expected gross profits to be realized over the estimated lives of the contracts, similar to DAC. Other income includes advisory fee income from the Life and Retirement broker dealer business.
Cash	Cash represents cash on hand and demand deposits.
Premiums and other receivables - net	Premiums and other receivables – net of allowance for credit losses and disputes include premium balances receivable, amounts due from agents and brokers and policyholders, trade receivables for the Direct Investment book (DIB) and Global Capital Markets (GCM) and other receivables. Trade receivables for GCM include cash collateral posted to derivative counterparties that is not eligible to be netted against derivative liabilities. The allowance for credit losses and disputes on premiums and other receivables was $ 205 million and $ 178 million at December 31, 2020 and 2019, respectively.
Deposit assets and liabilities	Deposit assets and liabilities: We have entered into certain insurance and reinsurance contracts, primarily in our General Insurance companies, 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 Other 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 Other assets in the Consolidated Balance Sheets. The deposit asset or liability is adjusted as amounts are paid, consistent with the underlying contracts.
Other assets	Other assets consist of sales inducement assets, 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 assets of businesses classified as held-for-sale. We offer sales inducements which include enhanced crediting rates or bonus payments to contract holders (bonus interest) on certain annuity and investment contract products. Such amounts are deferred and amortized over the life of the contract using the same methodology and assumptions used to amortize DAC (see Note 9 herein) . To qualify for such accounting treatment, the bonus interest must be explicitly identified in the contract at inception. We must also demonstrate that such amounts are incremental to amounts we credit on similar contracts without bonus interest, and are higher than the contract’s expected ongoing crediting rates for periods after the bonus period. The deferred bonus interest and other deferred sales inducement assets totaled $ 281 million and $ 430 million at December 31, 2020 and 2019, respectively. The amortization expense associated with these assets is reported within Interest credited to policyholder account balances in the Consolidated Statements of Income. Such amortization expense totaled $ 60 million, $ 79 million and $ 156 million for the years ended December 31, 2020, 2019 and 2018, respectively. 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 equipment). 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. There is a diverse pool of assets supporting the funds withheld arrangements with Fortitude Re. The following summarizes the composition of the pool of assets as of December 31, 2020:
Goodwill	GOODWILL Effective July 1, 2019, we changed the date of our annual goodwill impairment testing from December 31 to July 1. This change does not represent a material change to our method of applying current accounting guidance and is preferable as it better aligns with our strategic planning and forecasting process. This change did not delay, accelerate or avoid any impairment charge and was applied prospectively. We performed our annual goodwill impairment tests of all reporting units using a combination of both qualitative and quantitative assessments and concluded that our goodwill was not impaired. Our goodwill balance was $ 4.1 billion at December 31, 2020. For further information on goodwill see Note 12 to the Consolidated Financial Statements. 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 annually or more frequently if circumstances indicate an impairment may have occurred. At December 31, 2020, as a result of the 2020 segment changes, goodwill is reported within our General Insurance business – North America and International operating segments, our Life and Retirement business – Life Insurance operating segment and our Other Operations segment. When a business is transferred from one reporting unit to another, as occurred as part of the 2020 segment changes, goodwill from the original operating segment 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 an operating segment 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 an operating segment 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 operating segment and compare the estimated fair value with the carrying amount of the operating segment, including allocated goodwill. The estimate of an operating segment’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 an operating segment to be used in the impairment test. If the estimated fair value of an operating segment exceeds its carrying amount, goodwill is not impaired. If the carrying value of an operating segment exceeds its estimated fair value, goodwill associated with that operating segment 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 earnings. The date of our annual goodwill Impairment testing is July 1. We performed our annual goodwill impairment tests of all reporting units and reassessed goodwill as a result of the aforementioned segment change using a combination of both qualitative and quantitative assessments and concluded that our goodwill was not impaired. The following table presents the changes in goodwill by operating segment: General Insurance North Life Other (in millions) America International Insurance Operations Total Balance at January 1, 2018: Goodwill - gross $ 1,473 $ 3,269 $ 270 $ 59 $ 5,071 Accumulated impairments ( 1,145) ( 2,255) ( 67) ( 10) ( 3,477) Net goodwill 328 1,014 203 49 1,594 Increase (decrease) due to: Acquisitions (a) 2,332 157 46 9 2,544 Other ( 12) ( 48) ( 5) 9 ( 56) Balance at December 31, 2018: Goodwill - gross 3,793 3,378 311 77 7,559 Accumulated impairments ( 1,145) ( 2,255) ( 67) ( 10) ( 3,477) Net goodwill 2,648 1,123 244 67 4,082 Increase (decrease) due to: Acquisitions - 20 - - 20 Other (b) - 26 ( 77) ( 13) ( 64) Balance at December 31, 2019: Goodwill - gross 3,793 3,424 234 64 7,515 Accumulated impairments ( 1,145) ( 2,255) ( 67) ( 10) ( 3,477) Net goodwill 2,648 1,169 167 54 4,038 Increase (decrease) due to: Dispositions ( 2) - - ( 4) ( 6) Other - 32 10 - 42 Balance at December 31, 2020: Goodwill - gross 3,791 3,456 244 60 7,551 Accumulated impairments ( 1,145) ( 2,255) ( 67) ( 10) ( 3,477) Net goodwill $ 2,646 $ 1,201 $ 177 $ 50 $ 4,074 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 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.
Separate accounts	Separate accounts represent funds for which investment income and investment gains and losses accrue directly to the policyholders who bear the investment risk. Each account has specific investment objectives and the assets are carried at fair value. The assets of each account are legally segregated and are not subject to claims that arise from any of our other businesses. The liabilities for these accounts are equal to the account assets. Separate accounts may also include deposits for funds held under stable value wrap funding agreements, although the majority of stable value wrap sales are measured based on the notional amount included in assets under management and do not include the receipt of funds. For a more detailed discussion of separate accounts see Note 14 herein .
Long-Duration Contracts	We report variable contracts within the separate accounts when investment income and investment gains and losses accrue directly to, and investment risk is borne by, the contract holder and the separate account meets additional accounting criteria to qualify for separate account treatment. The assets supporting the variable portion of variable annuity and variable universal life contracts that qualify for separate account treatment are carried at fair value and reported as Separate account assets, with an equivalent summary total reported as Separate account liabilities. Policy values for variable products and investment contracts are expressed in terms of investment units. Each unit is linked to an asset portfolio. The value of a unit increases or decreases based on the value of the linked asset portfolio. The current liability at any time is the sum of the current unit value of all investment units in the separate accounts, plus any liabilities for guaranteed minimum death benefits (GMDB) or guaranteed minimum withdrawal benefits (GMWB) included in Future policy benefits or Policyholder contract deposits, respectively. Amounts assessed against the contract holders for mortality, administrative and other services are included in revenue. Net investment income, net investment gains and losses, changes in fair value of assets, and policyholder account deposits and withdrawals related to separate accounts are excluded from the Consolidated Statements of Income, Comprehensive Income (Loss) and Cash Flows.
Other liabilities	Other liabilities consist of other funds on deposit, other payables, securities sold under agreements to repurchase, securities sold but not yet purchased, derivative liabilities, deferred gains on retroactive reinsurance agreements and liabilities of businesses classified as held-for-sale. Also included in Other liabilities are trade payables for the DIB and GCM, which include balances due to clearing brokers and exchanges. Trade payables for GCM also include cash collateral received from derivative counterparties that contractually cannot be netted against derivative assets. Securities sold but not yet purchased represent sales of securities not owned at the time of sale. The obligations arising from such transactions are recorded on a trade-date basis and carried at fair value. Fair values of securities sold but not yet purchased are based on current market prices.
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.
Accounting Standards Adopted During 2020	Accounting Standards Adopted During 2020 Financial Instruments – Credit Losses In June 2016, the FASB issued an accounting standard that changed how entities account for current expected credit losses (CECL) for most financial assets, premiums receivable, trade receivables, off-balance sheet exposures and reinsurance receivables (the Financial Instruments Credit Losses Standard). The standard requires an allowance for credit losses based on the expectation of lifetime credit losses related to such financial assets subject to credit losses, including loans measured at amortized cost, reinsurance receivables and certain off-balance sheet credit exposures. Additionally, the impairment of available-for-sale debt securities, including purchased credit deteriorated (PCD) securities, is subject to the new guidance and is measured in a similar manner, except that losses are recognized as allowances rather than reductions in the amortized cost of the securities. The standard allows for reversals of credit impairments in the event that the credit of an issuer improves. The standard also requires additional disclosures. We adopted the standard on its effective date of January 1, 2020 using a modified retrospective method, which requires a cumulative effect adjustment to retained earnings. As of January 1, 2020, the impact of the adoption of the standard was a reduction in opening retained earnings of $ 487 million (after-tax) primarily driven by commercial mortgage loans, and, to a lesser extent, reinsurance receivables and recoverables. The following table provides a rollforward of our allowance, including credit losses, in connection with the adoption of the Financial Instruments Credit Losses Standard as well as cross references to the applicable notes herein for additional information: Year Ended December 31, 2020 Balance, Cumulative Effect Purchased Credit Incremental Write-offs and Beginning Adjustment as of Deteriorated Initial Increase (Decrease) Other Changes Balance, (in millions) of Year January 1, 2020 Allowance Recognized in Income in the Allowance (h) End of Year Securities available for sale (a) $ - $ - $ 33 $ 280 $ ( 127) $ 186 Mortgage and other loan receivables (b) 438 318 - 75 ( 17) 814 Reinsurance recoverables (inclusive of deposit accounted assets) (c) 151 224 - 9 ( 9) 375 Premiums and other receivables (d) 178 34 - 6 ( 13) 205 Contractual deductible recoverables (e) - 14 - - - 14 Commercial mortgage loan commitments (f) - 51 - 28 - 79 Total $ 767 $ 641 $ 33 $ 398 $ ( 166) $ 1,673 Secondary impacts to certain long-duration insurance contracts (g) ( 27) Tax impact ( 127) Total cumulative effect adjustment $ 487 (a) The allowance for credit losses is reported in Bonds available for sale in the Consolidated Balance Sheets. Changes in the allowance for credit losses are reported in Net realized capital gains (losses) in the Consolidated Statements of Income. Refer to Note 6 for additional information. (b) The allowance for credit losses is reported in Mortgage and other loans receivable in the Consolidated Balance Sheets. Changes in the allowance for credit losses are reported in Net realized capital gains (losses) in the Consolidated Statements of Income. Refer to Note 7 for additional information. (c) The allowance for credit losses and disputes is reported in Reinsurance assets – other and Reinsurance assets – Fortitude Re for reinsurance contracts that contain sufficient insurance risk, and the allowance for credit losses is reported in Other assets for insurance and reinsurance contracts that do not contain sufficient insurance risk in the Consolidated Balance Sheets. Changes in the allowance for credit losses are reported in Policyholder benefits and losses incurred for reinsurance contracts that do contain sufficient insurance risk and premiums for contracts that do not contain sufficient insurance risk in the Consolidated Statements of Income. Refer to Note 8 for additional information. (d) The allowance for credit losses and disputes is reported in Premiums and other receivables in the Consolidated Balance Sheets. Changes in the allowance for credit losses and disputes are reported in General operating and other expenses in the Consolidated Statements of Income. Refer to Note 2 for additional information. (e) The allowance for credit losses is reported in Liability for unpaid losses and loss adjustment expenses in the Consolidated Balance Sheets. Changes in the allowance for credit losses are reported in Policyholder benefits and losses incurred in the Consolidated Statements of Income. Refer to Note 13 for additional information. (f) The allowance for credit losses is reported in Other liabilities in the Consolidated Balance Sheets. Changes in the allowance for credit losses are reported in Net realized capital gains (losses) in the Consolidated Statements of Income. Refer to Note 7 for additional information. (g) This reflects adjustments to the amortization of DAC, unearned revenue reserve and sales inducement assets as well as impacts on the future policy benefits for certain universal life and variable annuity contracts. (h) A write-off does not generally result in an incremental loss to AIG. Prior to a write-off occurring, the allowance for the credit loss is increased or decreased to reflect AIG’s expectation of the credit loss to be incurred. Accordingly, when a write-off occurs, the allowance is reversed for the same amount, resulting in no incremental loss to AIG. The following presents the impact of the adoption of the standard on premiums and other receivables. Premiums and other receivables – Credit Losses Premiums and other receivables, net of allowance for credit losses include premium balances receivable, amounts due from agents and brokers and policyholders, trade receivables for GCM and other receivables. Trade receivables for GCM include cash collateral posted to derivative counterparties that is not eligible to be netted against derivative liabilities. The allowance for credit losses and disputes for premiums and other receivables was $ 205 million at December 31, 2020. Our allowance for credit losses for premium receivables considers a combination of internal and external information relating to past events, current conditions and reasonable and supportable forecasts. Our allowance contemplates our contractual provisions. Upon default or delinquency of the policyholder we may be able to cease coverage for the remaining period. In certain jurisdictions we are unable to cancel coverage even in the event of delinquency or default by the policyholder. We consider premium and other receivable balances to be past due if the payment is not received after 90 days from the contractual obligation due date and record an allowance for disputes when there is reasonable uncertainty of the collectability of a disputed amount during the reporting period. For further information regarding the impacts of the adoption of this standard see Notes 6, 7, 8 and 13 to the Consolidated Financial Statements. Simplifying the Test for Goodwill Impairment In January 2017, the FASB issued an accounting standard that eliminates the requirement to calculate the implied fair value of goodwill, through a hypothetical purchase price allocation, to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on 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. An entity should also consider income tax effects from tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. We adopted the standard on its effective date of January 1, 2020. The adoption of the standard did not have a material impact on our financial position, results of operations or cash flows. Cloud Computing Arrangements In August 2018, the FASB issued an accounting standard that aligns the requirements for capitalizing implementation costs incurred in a cloud computing (or hosting) arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). Capitalized implementation costs must be amortized over the term of the hosting arrangement. The accounting for the service element is not affected by the amendments in this update. We adopted the standard prospectively on its effective date of January 1, 2020. The adoption of the standard did not have a material impact on our consolidated financial position, results of operations or cash flows. Financial Disclosures About Guarantors and Issuers of Guaranteed Securities and Affiliates In March 2020, the Securities and Exchange Commission (SEC) adopted amendments to simplify and streamline the disclosure requirements for guarantors and issuers of guaranteed securities registered or being registered, and issuers’ affiliates whose securities collateralize securities registered or being registered. Currently, the SEC permits the omission of separate financial statements of subsidiary issuers and guarantors when certain conditions are met and the parent company provides summarized financial information of the subsidiary issuers and guarantors. The amendments, among other things, allow companies to cease providing summarized financial information if the subsidiary issuer’s or guarantor’s reporting obligation has been suspended. The amendments are effective January 4, 2021, with early adoption permitted. Effective March 31, 2020, AIG early adopted the amendment and ceased providing the summarized information for the subsidiary issuers and guarantors because the subsidiaries issuer’s reporting obligations have been suspended.
Future Application of Accounting Standards	Future Application of Accounting Standards Targeted Improvements to the Accounting for Long-Duration Contracts In August 2018, the FASB issued an accounting standard update with the objective of making targeted improvements to the existing recognition, measurement, presentation, and disclosure requirements for long-duration contracts issued by an insurance entity. The standard prescribes significant and comprehensive changes to recognition, measurement, presentation and disclosure as summarized below:  Requires the review and if necessary update of future policy benefit assumptions at least annually for traditional and limited pay long duration contracts, with the recognition and separate presentation of any resulting re-measurement gain or loss (except for discount rate changes as noted below) in the income statement.  Requires the discount rate assumption to be updated at the end of each reporting period using an upper medium grade (low-credit risk) fixed income instrument yield that maximizes the use of observable market inputs and recognizes the impact of changes to discount rates in other comprehensive income.  Simplifies the amortization of DAC to a constant level basis over the expected term of the related contracts with adjustments for unexpected terminations, but no longer requires an impairment test.  Requires the measurement of all market risk benefits associated with deposit (or account balance) contracts at fair value through the income statement with the exception of instrument-specific credit risk changes, which will be recognized in other comprehensive income.  Increased disclosures of disaggregated rollforwards of policy benefits, account balances, market risk benefits, separate account liabilities and information about significant inputs, judgments and methods used in measurement and changes thereto and impact of those changes. In November 2020, the FASB issued ASU 2020-11, which deferred the effective date of the standard for all entities. Our implementation efforts are underway for a January 1, 2023 effective date; we continue to evaluate the method of adoption and impact of the standard on our reported consolidated financial condition, results of operations, cash flows and required disclosures The adoption of this standard is expected to have a significant impact on our consolidated financial condition, results of operations, cash flows and required disclosures, as well as systems, processes and controls. Income Tax On December 18, 2019, the FASB issued an accounting standard that simplifies the accounting for income taxes by eliminating certain exceptions to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The amendments also simplified other areas including the accounting for franchise taxes and enacted tax laws or rates, and clarified the accounting for transactions that result in the step-up in the tax basis of goodwill. The standard is effective on January 1, 2021, with early adoption permitted. The impact is not material to our consolidated financial condition, results of operations and cash flows. Reference Rate Reform On March 12, 2020, the FASB issued an accounting standard that provides temporary optional guidance to ease the potential burden in accounting for reference rate reform. The standard allows us to account for certain contract modifications that result from the discontinuation of the London Inter-Bank Offered Rate (LIBOR) or another reference rate as a continuation of the existing contract without additional analysis. This guidance is not expected to have a significant impact on our consolidated financial statements and notes to the consolidated financial statements. Where applicable, we would account for the change for the modification due to the discontinuation of LIBOR or another reference rate as a continuation of the existing contract. As part of our implementation efforts, we will continue to assess our operational readiness and current and alternative reference rates’ merits, limitations, risks and suitability for our investment and insurance processes. This standard may be elected and applied prospectively over time from March 12, 2020 through December 31, 2022 as reference rate reform activities occur. We are evaluating the method of adoption and impact of the standard on our reported consolidated financial condition, results of operations, cash flows and required disclosures. Clarification of Accounting for Certain Equity Method Investments On January 16, 2020, the FASB issued an accounting standard to clarify how a previously issued standard regarding a company’s ability to measure the fair value of certain equity securities without a readily determinable fair value should interact with equity method investments standards. The previously issued standard provides that such equity securities could be measured at cost, minus impairment, if any, unless an observable transaction for an identical or similar security occurs (measurement alternative). The new standard clarifies that a company should consider observable transactions that require the company to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with the equity method immediately before applying or upon discontinuing the equity method. The standard further clarifies that, when determining the accounting for certain forward contracts and purchased options a company should not consider, whether upon settlement or exercise, if the underlying securities would be accounted for under the equity method or fair value option. The standard is effective for interim and annual reporting periods beginning after December 15, 2020. We do not expect the adoption of this standard to be material to our reported consolidated financial condition, results of operations, cash flows and required disclosures.
Credit Losses	Financial Instruments – Credit Losses In June 2016, the FASB issued an accounting standard that changed how entities account for current expected credit losses (CECL) for most financial assets, premiums receivable, trade receivables, off-balance sheet exposures and reinsurance receivables (the Financial Instruments Credit Losses Standard). The standard requires an allowance for credit losses based on the expectation of lifetime credit losses related to such financial assets subject to credit losses, including loans measured at amortized cost, reinsurance receivables and certain off-balance sheet credit exposures. Additionally, the impairment of available-for-sale debt securities, including purchased credit deteriorated (PCD) securities, is subject to the new guidance and is measured in a similar manner, except that losses are recognized as allowances rather than reductions in the amortized cost of the securities. The standard allows for reversals of credit impairments in the event that the credit of an issuer improves. The standard also requires additional disclosures. We adopted the standard on its effective date of January 1, 2020 using a modified retrospective method, which requires a cumulative effect adjustment to retained earnings. As of January 1, 2020, the impact of the adoption of the standard was a reduction in opening retained earnings of $ 487 million (after-tax) primarily driven by commercial mortgage loans, and, to a lesser extent, reinsurance receivables and recoverables. The following table provides a rollforward of our allowance, including credit losses, in connection with the adoption of the Financial Instruments Credit Losses Standard as well as cross references to the applicable notes herein for additional information: Year Ended December 31, 2020 Balance, Cumulative Effect Purchased Credit Incremental Write-offs and Beginning Adjustment as of Deteriorated Initial Increase (Decrease) Other Changes Balance, (in millions) of Year January 1, 2020 Allowance Recognized in Income in the Allowance (h) End of Year Securities available for sale (a) $ - $ - $ 33 $ 280 $ ( 127) $ 186 Mortgage and other loan receivables (b) 438 318 - 75 ( 17) 814 Reinsurance recoverables (inclusive of deposit accounted assets) (c) 151 224 - 9 ( 9) 375 Premiums and other receivables (d) 178 34 - 6 ( 13) 205 Contractual deductible recoverables (e) - 14 - - - 14 Commercial mortgage loan commitments (f) - 51 - 28 - 79 Total $ 767 $ 641 $ 33 $ 398 $ ( 166) $ 1,673 Secondary impacts to certain long-duration insurance contracts (g) ( 27) Tax impact ( 127) Total cumulative effect adjustment $ 487 (a) The allowance for credit losses is reported in Bonds available for sale in the Consolidated Balance Sheets.

Changes in the allowance for credit losses are reported in Net realized capital gains (losses) in the Consolidated Statements of Income. Refer to Note 7 for additional information. (g) This reflects adjustments to the amortization of DAC, unearned revenue reserve and sales inducement assets as well as impacts on the future policy benefits for certain universal life and variable annuity contracts. (h) A write-off does not generally result in an incremental loss to AIG. Prior to a write-off occurring, the allowance for the credit loss is increased or decreased to reflect AIG’s expectation of the credit loss to be incurred. Accordingly, when a write-off occurs, the allowance is reversed for the same amount, resulting in no incremental loss to AIG. The following presents the impact of the adoption of the standard on premiums and other receivables. Premiums and other receivables – Credit Losses Premiums and other receivables, net of allowance for credit losses include premium balances receivable, amounts due from agents and brokers and policyholders, trade receivables for GCM and other receivables. Trade receivables for GCM include cash collateral posted to derivative counterparties that is not eligible to be netted against derivative liabilities. The allowance for credit losses and disputes for premiums and other receivables was $ 205 million at December 31, 2020. Our allowance for credit losses for premium receivables considers a combination of internal and external information relating to past events, current conditions and reasonable and supportable forecasts. Our allowance contemplates our contractual provisions. Upon default or delinquency of the policyholder we may be able to cease coverage for the remaining period. In certain jurisdictions we are unable to cancel coverage even in the event of delinquency or default by the policyholder. We consider premium and other receivable balances to be past due if the payment is not received after 90 days from the contractual obligation due date and record an allowance for disputes when there is reasonable uncertainty of the collectability of a disputed amount during the reporting period. For further information regarding the impacts of the adoption of this standard see Notes 6, 7, 8 and 13 to the Consolidated Financial Statements. 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. Reinsurance assets include reinsurance recoverables on unpaid losses and loss adjustment expenses that are estimated as part of our loss reserving process and, consequently, are subject to similar judgments and uncertainties as the estimation of gross loss reserves. Similarly, Other assets include reinsurance recoverables for contracts which are accounted for as deposits. 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 uncollectable reinsurance that reduces the carrying amount of reinsurance and other assets on the consolidated balance sheets (collectively, the reinsurance recoverable balances). 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 determined by the Obligor Risk Ratings (ORRs) we assign to each reinsurer based upon our financial reviews; insurers 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 rating. The allowance for credit losses excludes disputed amounts. An allowance for disputes is established for a reinsurance recoverable using the losses incurred model for contingencies. The total reinsurance recoverables as of December 31, 2020 were $ 75.8 billion. As of that date, utilizing AIG’s ORRs, (i) approximately 92 percent of the reinsurance recoverables were investment grade, of which 52 percent related to General Insurance and 40 percent related to Life and Retirement; (ii) approximately 7 percent of the reinsurance recoverables were non-investment grade, the majority of which related to General Insurance; (iii) less than one one As of December 31, 2020, approximately 64 percent of our non-investment grade reinsurance exposure related to captive insurers. These arrangements are typically collateralized by letters of credit, funds withheld or trust agreements. Reinsurance Recoverable Allowance The following table presents a rollforward of the reinsurance recoverable allowance: Year Ended December 31, 2020 General Life and (in millions) Insurance Retirement Total Balance, beginning of period $ 111 $ 40 $ 151 Initial allowance upon CECL adoption 202 22 224 Current period provision for expected credit losses and disputes ( 12) 21 9 Write-offs charged against the allowance for credit losses and disputes ( 9) - ( 9) Balance, end of year $ 292 $ 83 $ 375 There were no material recoveries of credit losses previously written off for the year ended December 31, 2020. Past-Due Status We consider a reinsurance asset to be past due when it is 90 days past due. The allowance for credit losses is estimated excluding disputed amounts. An allowance for disputes is established using the losses incurred method for contingencies. Past due balances on claims that are not in dispute were not material for any of the periods presented.

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 CDO 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. Because the valuation methodology for embedded derivatives within Policyholder contract deposits uses a range of inputs that vary at the contract level over the cash flow projection period, management believes that presenting a range, rather than weighted average, is a more meaningful representation of the unobservable inputs used in the valuation. (d) The Fortitude Re funds withheld payable has been excluded from the above table. As discussed in Note 8, the Fortitude Re funds withheld payable is created through modco and funds withheld reinsurance arrangements where the investments supporting the reinsurance agreements are withheld by, and continue to reside on AIG’s balance sheet. This embedded derivative is valued as a total return swap with reference to the fair value of the invested assets held by AIG. Accordingly, the unobservable inputs utilized in the valuation of the embedded derivative are a component of the invested assets supporting the reinsurance agreements that are held on AIG’s balance sheet. (e) Mortality inputs are shown as multipliers of the 2012 Individual Annuity Mortality Basic table. (f) The non-performance risk adjustment (NPA) applied as a spread over risk-free curve for discounting. (g) The partial withdrawal utilization unobservable input range shown applies only to policies with guaranteed minimum withdrawal benefit riders that are accounted for as an embedded derivative. The total embedded derivative liability at December 31, 2020 is approximately $ 726 million. The remaining guaranteed minimum riders on the index annuities are valued under the accounting guidance for certain nontraditional long-duration contracts.

The number of common shares excluded from the calculation was 5,401,597 shares. (b) Dilutive common shares included our share-based employee compensation plans, and a weighted average portion of the 10-year warrants issued to AIG shareholders as part of AIG’s recapitalization in January 2011, which expired in January 2021. The number of common shares excluded from diluted shares outstanding was 68.7 million, 20.0 million and 19.6 million for the years ended December 31, 2020, 2019 and 2018, respectively, because the effect of including those common shares in the calculation would have been anti-dilutive.
