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. 4,5
What Is Management Liability Insurance?
Management liability packages can combine D&O and employment-practices coverage for leader and workplace claims, while benefit-plan protection may be a separate part. Shared limits can let a claim in one part reduce what is available for another, so compare the limits across the quote. 7,8,9,10,11,12
Key Differences in Management Liability Insurance
Aon centers its program on professional partnerships
AIG’s portfolio lists directors and officers, employment practices, fiduciary, crime and kidnap-and-ransom products. Aon describes management-liability programs designed for professional partnerships, protecting partners and managers from business-operation liabilities. That focus gives law, accounting and consulting firms a partnership-specific advisory route, while AIG’s list spans multiple management-risk products and organization types. Ask Aon how its program fits your partnership structure and which insurers would issue the policies. 3 6
AIG names a broader range of organization types
AIG describes solutions for public, private and nonprofit organizations, financial institutions and professional-services firms. Aon’s cited practice identifies law, accounting and consulting firms as its audience; that description does not establish eligibility for every firm. AIG links to applications and national product contacts, while Aon frames its service as brokerage and advice. 3 6
