Overview

American International Group, Inc. (AIG) is a large multinational company principally known for insurance and related financial services. Headquartered in New York City, the company operates worldwide with major regional centers and multiple stock market listings. Historically one of the largest insurers by assets and market reach, AIG has played a prominent role in global insurance markets and in wider financial markets through its underwriting, investment and risk-management activities. It is listed publicly — for example on the NYSE and on other exchanges such as Tokyo — and is often referenced in industry rankings like the Forbes Global 2000.

Structure and operations

AIG’s operations are organized by geography and by lines of business. The company maintains a presence across North America, Europe and Asia with principal regional offices: based in New York City for its global headquarters, a UK headquarters in London, Continental European operations centered in Paris, and an Asian headquarters in Hong Kong. Its businesses include property and casualty insurance, life insurance and retirement products, specialty lines, and institutional client services. AIG’s corporate website and regulatory filings provide details on subsidiaries, capital structure and market segments; the firm is often cited in discussions of the broader insurance industry.

History and the 2008 financial crisis

Founded in the early 20th century as an international insurer, AIG expanded through underwriting, acquisitions and global growth to become a major financial institution. A key turning point occurred during the 2007–2009 financial crisis. On September 16, 2008, U.S. authorities announced emergency financial assistance for AIG: the Federal Reserve Bank arranged a loan of approximately $85 billion in exchange for a large equity position in the company, and AIG’s board accepted the terms that day. This intervention was one of the most visible examples of government action during the crisis and prompted extensive restructuring, asset sales and regulatory attention.

Products, clients and uses

AIG provides a range of products to individuals, businesses and institutional clients. Typical offerings include:

  • Personal and commercial property and casualty insurance (homes, automobiles, commercial property).
  • Life insurance and annuities for retirement planning and wealth transfer.
  • Specialty insurance and risk-transfer solutions for niche industries and large corporate clients.
  • Institutional investment products and asset management services.

These products support everyday financial protection needs, corporate risk management and long-term savings strategies.

Significance and notable facts

AIG’s size and interconnectedness with global capital markets made it a focal point during financial stress, and its inclusion in market indices underscored its economic importance — it was added to the Dow Jones Industrial Average in 2004 and appeared in prominent company rankings. The company’s experience in the late 2000s influenced banking and insurance regulation, prompted debates about systemic risk and led to substantial corporate restructuring. Observers often point to AIG when discussing risk concentration in financial firms and the policy choices that follow from systemic interventions.
