AIG vs 
Aon: How Do They Compare for Workers’ Compensation Insurance?
What Is AIG?
AIG is the marketing name for American International Group, Inc.; AIG says its insurance products are written or provided by subsidiaries or affiliates. Its U.S. business pages list commercial casualty, property, cyber, management and professional liability, and specialty programs, but a brand-level page does not identify the insurer for a particular policy. 1,2
What Is Aon?
Aon’s U.S. Commercial Risk terms describe brokerage for certain insurance programs, while its Middle Market page describes a dedicated practice for mid-sized organizations across North America. The public materials reviewed do not identify the licensed producer or insurer for a particular placement. Ask which entity will produce each line and which insurer will issue the policy; request jurisdiction details for the proposed placement and ask how compensation and claim notice work for your account. 5,6
What Is Workers’ Compensation Insurance?
Workers’ compensation can pay medical care and part of an employee’s lost wages after a work-related injury or illness. If you have staff, check who is covered in each state; owners, contractors and some workers may be treated differently. 8,9,10,11
Key Differences in Workers’ Compensation Insurance
Program design and brokerage
AIG describes customized structures using deductibles, self-insured retentions, captives, or retrospective programs for organizations that retain risk. Aon brokers workers’ compensation within a global construction practice serving contractors, owners, engineers, and other project participants. Ask AIG which retained-risk design may fit and Aon which carrier markets serve your project. 3 7
Project advice versus policy terms
Aon offers project risk advice to develop transfer, management, and mitigation strategies, but its reviewed page does not describe statutory benefits or a particular policy’s response. AIG lists workers’ compensation in corporate casualty and its nationwide motorsports program. Ask both for the issuing insurer, state forms, and the risk-advisory work included for your operation. 4 7
