Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	1. Basis of Presentation American International Group, Inc. (AIG) is a leading global insurance organization. AIG provides insurance solutions that help businesses and individuals in approximately 190 countries and jurisdictions protect their assets and manage risks through AIG operations and network partners. Unless the context indicates otherwise, the terms “AIG,” “we,” “us,” “our” or "the Company" mean American International Group, Inc. and its consolidated subsidiaries, and the term “AIG Parent” means American International Group, Inc. and not any of its consolidated subsidiaries. These unaudited Condensed Consolidated Financial Statements do not include all disclosures that are normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States (GAAP) and should be read in conjunction with the audited Consolidated Financial Statements and the related notes included in our Annual Report on Form 10-K for the year ended December 31, 2023 (the 2023 Annual Report). The condensed consolidated financial information as of December 31, 2023 included herein has been derived from the audited Consolidated Financial Statements in the 2023 Annual Report. In the opinion of management, these Condensed Consolidated Financial Statements contain normal recurring adjustments, including eliminations of material intercompany accounts and transactions, necessary for a fair statement of the results presented herein. Operating results for the three months ended March 31, 2024, are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. We evaluated the need to recognize or disclose events that occurred subsequent to March 31, 2024 and prior to the issuance of these Condensed Consolidated Financial Statements. SALES/DISPOSALS OF ASSETS AND BUSINESSES AIG Life Limited On April 8, 2024, Corebridge Financial, Inc. (Corebridge) completed the sale of AIG Life Limited (AIG Life) to Aviva plc and received gross proceeds of £453 million ($569 million). For further details on this transaction, see Note 4. Separation of Life and Retirement Business and Relationship with Blackstone Inc. AIG owns 52.7 percent of the outstanding common stock of Corebridge as of March 31, 2024. Corebridge is the holding company for AIG’s Life and Retirement business. AIG continues to consolidate Corebridge in AIG’s Condensed Consolidated Financial Statements. The portion of equity interest of Corebridge that AIG does not own is reflected as noncontrolling interest in AIG’s Condensed Consolidated Financial Statements. In the three months ended March 31, 2024, Corebridge repurchased 9.5 million shares of Corebridge common stock for an aggregate purchase price of $243 million. As a result, AIG recorded a decrease of $83 million in Total AIG shareholders' equity. Blackstone Inc. (Blackstone) owns a 10.1 percent equity stake in Corebridge as of March 31, 2024. Blackstone is required to hold its ownership interest in Corebridge, subject to exceptions currently permitting Blackstone to sell 67 percent and 75 percent of its ownership interest after September 19, 2024 and 2025, respectively, with the transfer restrictions terminating in full on September 19, 2027. USE OF ESTIMATES The preparation of financial statements in accordance with U.S. GAAP requires the application of accounting policies that often involve a significant degree of judgment. Accounting policies that we believe are most dependent on the application of estimates and assumptions are considered our critical accounting estimates and are related to the determination of: •loss reserves; •valuation of future policy benefit liabilities and recognition of measurement gains and losses; •valuation of market risk benefits (MRBs) related to guaranteed benefit features of variable annuity, fixed annuity and fixed index annuity products; •valuation of embedded derivative liabilities for fixed index annuity and index universal life products; •reinsurance assets, including the allowance for credit losses and disputes; •goodwill impairment; •allowance for credit losses on certain investments, primarily on loans and available for sale fixed maturity securities; •fair value measurements of certain financial assets and financial liabilities; and •income taxes, in particular the recoverability of our deferred tax asset and establishment of provisions for uncertain tax positions. These accounting estimates require the use of assumptions about matters, some of which are highly uncertain at the time of estimation. To the extent actual experience differs from the assumptions used, our consolidated financial condition, results of operations and cash flows could be materially affected.
