Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	1. Basis of Presentation American International Group, Inc. is a leading global insurance organization. AIG provides insurance solutions that help businesses and individuals in over 200 countries and jurisdictions protect their assets and manage risks through AIG operations, licenses and authorizations as well as 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, 2025 (the 2025 Annual Report). The condensed consolidated financial information as of December 31, 2025 included herein has been derived from the audited Consolidated Financial Statements in the 2025 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. Results of operations for the three months ended March 31, 2026 are not necessarily indicative of the results that may be expected for the year ending December 31, 2026. We evaluated the need to recognize or disclose events that occurred subsequent to March 31, 2026 and prior to the issuance of these Condensed Consolidated Financial Statements. There were no significant subsequent events that required disclosure. STRATEGIC INVESTMENTS On February 6, 2026, AIG closed its previously announced acquisitions of (i) a 35 percent equity interest in Convex Group Limited (Convex), a global specialty insurer, for $2.1 billion and (ii) a 9.9 percent ownership stake in Onex Corporation (Onex), a global asset manager, for $642 million. AIG reflects its interest in Convex as an equity method investment in Other invested assets. The difference between the purchase price and the value of the underlying net assets acquired is primarily comprised of intangible assets and other basis differences of approximately $450 million and goodwill of approximately $550 million. AIG records its proportionate share of Convex’s net income less amortization of the basis differences described above as a component of Net investment income reported in General Insurance. On December 23, 2025, AIG entered into a whole account quota share agreement with Convex to reinsure 7.5 percent, 10.0 percent and 12.5 percent of Convex’s underwriting portfolio beginning in 2026, 2027 and 2028, respectively. The quota share agreement became effective starting on January 1, 2026. SALE OF ASSETS Corebridge On February 17, 2026, Corebridge Financial, Inc. (Corebridge) purchased 24.7 million shares of Corebridge common stock from AIG at a per share purchase price of $30.42 with aggregate proceeds to AIG Parent of $750 million. On March 23, 2026, in light of the reduction in AIG’s ownership interest in Corebridge, the two remaining AIG designees resigned from Corebridge's board of directors. As of March 31, 2026, AIG held 5.6 percent of the outstanding common stock of Corebridge and we concluded that we no longer have the ability to exert significant influence over Corebridge. AIG's remaining interest in Corebridge changed from being recognized as an equity method investment in Other invested assets to an equity security, at fair value on our Condensed Consolidated Balance Sheets. AIG continues to use Corebridge’s stock price as its fair value for reporting purposes. Dividends received from Corebridge and changes in its stock price continue to be recognized in Net investment income. USE OF ESTIMATES The preparation of financial statements in accordance with U.S. GAAP requires the application of accounting policies that often involve a significant degree of judgment. Accounting policies that we believe are most dependent on the application of estimates and assumptions are considered our critical accounting estimates and are related to the determination of: •loss reserves; •reinsurance assets; •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. OUT OF PERIOD ADJUSTMENTS - THREE MONTHS ENDED MARCH 31, 2025 During the three months ended March 31, 2025, we recorded out of period adjustments relating to prior years that increased Net income attributable to AIG common shareholders by $51 million and increased Income before income tax expense by $140 million. The out of period adjustments were primarily related to the recognition of gains on intercompany investment transactions and the settlement of derivative and collateral transactions. We evaluated the aggregate impact of these out of period adjustments and concluded they were not material to any previously issued interim and annual Consolidated Financial Statements and that the adjustments were not material to AIG’s Consolidated Financial Statements for the year ended December 31, 2025. Had these adjustments, which were determined not to be material, been recorded in their appropriate periods, Income before income tax expense for the year ended December 31, 2024 would have decreased by $79 million and would have increased for the years ended December 31, 2023 and 2022 by $34 million and $42 million (and all prior years by $143 million), respectively. Had these adjustments, which were determined not to be material, been recorded in their appropriate periods, Net income attributable to AIG common shareholders for the year ended December 31, 2024 would have decreased by $68 million and would have increased for the years ended December 31, 2023 and 2022 by $19 million and $23 million (and all prior years by $77 million), respectively.
