About
American International Group, Inc. (AIG) is a New York City-based global commercial property-casualty insurance company — publicly traded on the New York Stock Exchange (NYSE: AIG) as an S&P 500 Financials component — providing commercial insurance (property, casualty, financial lines, specialty), personal insurance, and reinsurance to businesses, organizations, and individuals in 200+ countries through approximately 26,000 employees. AIG has completed a decade-long strategic transformation from the systemically important financial institution (SIFI) that required a $185 billion US government bailout during the 2008 financial crisis — divesting life insurance (AIG Life and Retirement separated as Corebridge Financial, NYSE: CRBG, with AIG owning 48% stake following Corebridge's 2022 IPO and ongoing stake sales), non-core property assets, and non-insurance financial businesses — focusing the company exclusively on global commercial and specialty P&C insurance. In fiscal year 2024, AIG reported revenues of approximately $27 billion with adjusted after-tax income growing as underwriting profitability improved following the combined ratio improvement initiatives. CEO Peter Zaffino has repositioned AIG as a "best-in-class" global commercial insurer: achieving combined ratio below 90% in its General Insurance segment, expanding the portfolio toward specialty lines (financial lines — D&O, E&O, cyber insurance; marine and energy insurance; aerospace) with superior pricing power versus commodity commercial P&C. AIG's complete exit from the low-margin high-volatility consumer auto and homeowners insurance markets (sold to Safeco/Liberty Mutual, Assurant partnerships) refocuses underwriting capacity toward commercial and specialty lines with better long-term profitability.
