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
Markel Insurance: Specialty Business and Products
Markel Insurance is Markel Group's specialty and small-business insurance business, with offerings across packages, workers' compensation, cyber, professional and management liability, property, marine, and surety. Products use different insurers and distribution routes, so compare the issuer and terms shown on the specific quote. 4,5
What Is Fiduciary Liability Insurance?
Fiduciary liability can protect your company and plan fiduciaries when participants claim mishandling of an employee benefit plan. If you sponsor a retirement or health plan, check who is insured and whether both administration errors and fiduciary-breach claims are addressed. 7,8,9
Key Differences in Fiduciary Liability Insurance
Plan Audience and Covered Allegations
Markel identifies private companies, nonprofits and individuals who manage employee benefit plans as audiences for fiduciary liability, and describes claims tied to plan mismanagement, administrative errors or breach of duty. AIG names executives and other people or entities overseeing 401(k), pension and welfare plans. The audience descriptions overlap, but the buyer still needs to confirm that its particular plan and fiduciaries meet each insurer's eligibility and insured-person definitions. 3 6
Extensions and Policy Detail
AIG lists IRS Audit Protector, settlor coverage and an ACA extension, with availability and scope subject to the issued form. Markel's reviewed description says defense costs, settlements and judgments may respond to fiduciary claims subject to policy wording, but it does not list comparable extensions. Ask Markel about compliance features and AIG about selected options before treating either overview as the complete coverage grant. 3 6
