Overview
American International Group, Inc. (AIG) is a multinational insurance group headquartered in New York City. Its principal activities are commercial property and casualty insurance, personal insurance, life insurance, retirement products, annuities, and insurance-related risk-management services. AIG serves corporations, multinational enterprises, institutions, public-sector organizations, employers, and individual customers through operations and partner networks spanning more than 200 countries and jurisdictions. The group traces its origins to December 19, 1919, when Cornelius Vander Starr established American Asiatic Underwriters, a general insurance agency in Shanghai. Starr subsequently added life insurance operations and expanded through Asia, the Pacific, Latin America, Europe, and the United States. In 1939, as war disrupted the Asian business environment, he moved the headquarters to New York. After the Second World War, American International Underwriters expanded into Japan, Germany, France, Italy, the United Kingdom, and other markets, while acquisitions strengthened AIG’s U.S. presence. AIG became the umbrella company for most of C.V. Starr’s general and life insurance businesses in 1967 and became publicly traded in 1969. Under Maurice R. “Hank” Greenberg and later leaders, the company developed a broker-oriented distribution model and built specialized insurance capabilities in areas such as energy, transportation, shipping, pollution liability, political risk, multinational programs, and large commercial accounts. It also expanded into financial services and acquired businesses including International Lease Finance Corporation, SunAmerica, and American General. The company’s diversification created major vulnerabilities. In the mid-2000s, AIG became the subject of accounting and regulatory investigations, and Maurice Greenberg left the company in 2005. AIG’s Financial Products division had also written very large volumes of credit-default-swap protection on mortgage-related securities without adequate hedging or capital protection. When the U.S. housing and credit markets deteriorated, collateral calls and losses produced a severe liquidity crisis. In September 2008, the U.S. Federal Reserve and Treasury supported AIG with a rescue package that ultimately reached approximately $180 billion and involved government control of a substantial equity stake. The intervention prevented the group’s disorderly failure but led to asset sales, restructuring, public controversy, executive changes, and a substantial reduction in non-insurance activities. AIG repaid approximately $205 billion to the U.S. government by 2012, according to the cited reference material. After the crisis, AIG sold or separated numerous businesses and refocused on insurance. Its contemporary identity is centered on commercial insurance, specialty and multinational risk solutions, personal insurance, life insurance, and retirement and annuity products. In 2023, the company employed approximately 25,200 people. AIG also holds a prominent position in sports sponsorship through its title sponsorship of the AIG Women’s Open golf tournament.
History
AIG began on December 19, 1919, when Cornelius Vander Starr founded American Asiatic Underwriters in Shanghai. The original agency grew rapidly and expanded into life insurance two years later. By the late 1920s, the business had established offices across China and Southeast Asia, including the Philippines, the Dutch East Indies, and Malaya. Starr opened a U.S. office in 1926 under the American International Underwriters name and later pursued opportunities in Latin America. The Latin American network became strategically important when war disrupted the company’s Asian operations. In 1939, Starr moved the headquarters from Shanghai to New York City. After the Second World War, American International Underwriters entered Japan and Germany, initially serving American military personnel, and then developed a broader European presence in France, Italy, and the United Kingdom. In 1952, Starr acquired Globe & Rutgers Fire Insurance Company and American Home Fire Assurance Company, increasing the organization’s exposure to the U.S. market. By the end of the 1950s, C.V. Starr’s general and life insurance organization had agents and offices in more than 75 countries. In 1960, Starr recruited Hank Greenberg to develop international accident and health insurance. Greenberg reorganized a U.S. holding into a multiple-line carrier and emphasized independent brokers rather than salaried agents. The model allowed the company to distribute specialized products and price coverage according to underwriting returns. In 1967, American International Group, Inc. was incorporated as the umbrella organization for most of the group’s general and life insurance businesses. The company went public in 1969. During the 1970s, political changes restricted or ended parts of AIG’s Middle Eastern and Southeast Asian operations. The group nevertheless expanded into specialized energy, transportation, and marine insurance. During the 1980s, it added products such as pollution liability and political-risk insurance and continued to extend its international distribution network. In 1984, AIG listed its shares on the New York Stock Exchange. The 1990s brought further diversification. AIG acquired International Lease Finance Corporation, an aircraft-leasing business, and obtained a Chinese foreign insurance license in 1992. In 1999, it acquired SunAmerica, a retirement-savings company. In the early 2000s, AIG acquired American General, expanded its life and annuity activities, and entered additional markets including India. These moves increased the group’s scale but also contributed to a complex financial conglomerate structure. Regulatory and accounting problems became prominent in the mid-2000s. In 2004, AIG reached a settlement with the Securities and Exchange Commission and the Justice Department concerning regulatory matters and continued investigations into a non-traditional insurance product. In 2005, accounting investigations led to a restatement of earlier financial statements, the departure of Maurice Greenberg, and a major New York attorney general settlement. Martin Sullivan became chief executive during this period. AIG’s most consequential failure arose from its Financial Products division in London. The division sold extensive credit-default-swap protection on mortgage-related collateralized debt obligations. It did not adequately hedge the exposures or maintain sufficient protection against the collateral requirements that followed a decline in the value of the underlying securities. As credit markets deteriorated in 2007 and 2008, AIG faced escalating collateral calls and rating pressure. In September 2008, the Federal Reserve created an emergency secured lending facility, and the government ultimately provided approximately $180 billion in support while taking a controlling economic stake. The rescue was followed by a broad restructuring. AIG sold or transferred businesses, reduced its financial-products exposure, and concentrated on insurance. Asset disposals included international life-insurance operations and other non-core businesses. The company also faced public anger over executive bonuses announced in 2009 while taxpayers supported the group. AIG eventually repaid approximately $205 billion to the U.S. government by 2012. Since the crisis, AIG has operated primarily as an insurance and retirement group rather than as a pre-crisis-style financial conglomerate. Its continuing business scope includes commercial property and casualty insurance, specialty and multinational insurance, personal insurance, life insurance, annuities, and retirement solutions. The group maintains a global footprint while keeping its corporate headquarters in New York City.
