Company Description
American International Group, Inc. (AIG) is one of the world's largest insurance organizations, providing commercial and personal insurance products across more than 80 countries and jurisdictions. Headquartered in New York City and trading on the New York Stock Exchange, AIG has operated since 1919, building a global infrastructure that underwrites risk for multinational corporations, small businesses, and individual policyholders alike.
Core Business Operations
AIG generates revenue primarily through underwriting premiums and investment income across its insurance operations. The company's General Insurance division serves as its largest business segment, offering commercial lines coverage including property insurance, casualty insurance, financial lines, and specialty risk products. This segment underwrites complex risks for large corporations, including directors and officers liability, professional liability, and cyber insurance—coverage categories that require deep underwriting expertise and substantial capital reserves.
The company maintains significant presence in personal insurance markets, providing automobile, homeowners, and personal liability coverage through various distribution channels including independent agents, brokers, and direct-to-consumer platforms. AIG's global footprint allows it to insure risks that span multiple jurisdictions, a capability particularly valuable for multinational corporations with operations across diverse regulatory environments.
Market Position and Competitive Dynamics
AIG competes in the upper echelon of global insurance markets alongside carriers such as Chubb, Zurich Insurance, and Allianz. The company's competitive position rests on several structural advantages: its global licensing and regulatory infrastructure, accumulated underwriting data spanning decades, and balance sheet capacity to absorb large individual losses. In specialty lines such as excess casualty and financial institutions coverage, AIG ranks among the largest underwriters globally.
The commercial insurance market where AIG concentrates its operations requires substantial capital, regulatory approvals across jurisdictions, and relationships with major brokers—barriers that limit new entrants. AIG's long operating history has produced proprietary loss data that informs pricing decisions, particularly for complex risks where industry-wide actuarial tables provide limited guidance.
Underwriting and Risk Management
Insurance companies succeed or fail based on underwriting discipline—the ability to price risk accurately and avoid concentrations of correlated exposures. AIG employs teams of actuaries, underwriters, and risk engineers who evaluate potential policies, set premium rates, and structure coverage terms. The company's loss ratio—claims paid relative to premiums earned—serves as a key performance indicator watched closely by investors and analysts.
Reinsurance arrangements play a critical role in AIG's risk management strategy. By transferring portions of its underwritten risk to reinsurers, AIG limits its exposure to catastrophic events such as major hurricanes, earthquakes, or widespread liability claims. These arrangements also free up capital that would otherwise be held in reserve, improving return on equity when deployed effectively.
Investment Portfolio
Like all major insurers, AIG manages a substantial investment portfolio funded by policyholder premiums collected before claims are paid—known as insurance float. This portfolio generates investment income that supplements underwriting profits. AIG's investment strategy typically emphasizes fixed-income securities, particularly investment-grade corporate and government bonds, reflecting the need to match asset durations with expected liability payouts and maintain liquidity for claims payments.
Regulatory Environment
Insurance companies face extensive regulation at both state and international levels. In the United States, AIG must maintain licenses and comply with capital requirements in each state where it operates. The company files statutory financial statements with state regulators, maintains prescribed reserve levels, and submits to regular examinations. Internationally, AIG navigates varying regulatory frameworks including Solvency II requirements in Europe and local insurance laws across Asia, Latin America, and other regions.
Distribution Channels
AIG reaches customers through multiple distribution channels. Independent brokers and agents represent the primary channel for commercial insurance, where sophisticated buyers rely on intermediaries to navigate coverage options and negotiate terms. Retail partnerships, direct marketing, and digital platforms serve personal lines customers. The company also maintains relationships with major global insurance brokers who place coverage for the world's largest corporations.
