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 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
Published Fiduciary Features
AIG's Fiduciary Edge description addresses personal liability for people overseeing benefit plans and identifies penalty and compliance-program extensions subject to policy terms. Aon's professional-services practice lists fiduciary coverage among its property-and-casualty lines for law, accounting and consulting firms, but its reviewed page does not specify covered acts, plan types or exclusions. Buyers can use AIG's detail to frame a coverage discussion; Aon's public page requires a proposal and form before the actual grants can be compared. 3 6
Practice Scope and Advice
AIG describes specialized underwriting and claims teams, while Aon describes advisors using industry knowledge, data and tools for risk-management and human-capital decisions. Those are different published service descriptions, not evidence of a particular claim outcome. A professional-services firm should ask Aon how its fiduciary placement service applies to the firm's benefit plans and ask AIG which named extensions are available under the offered form. 3 6

|---|---|---|
| Role in This Line | AIG markets Fiduciary Liability Insurance Edge and related plan-fiduciary options.

Role in this product is limited to the description on the linked AIG source. | Aon presents Fiduciary Liability as a line its Professional Services Practice helps arrange or advise on for professional-service firms. Aon is describing a global brokerage and advisory service, not issuing the underlying policy. The producing legal entity and carrier for any particular placement are not named on this page. 6Company-reported. Aon’s global professional-services practice page. This establishes a marketed brokerage/advisory offering, not policy issuance or account-specific placement. |

Ask for both on the quote and binder. 6Not found in reviewed sources. Aon’s global practice page as reviewed 2026-09-30; no state-specific placement schedule or buyer quote was reviewed. This does not establish that Aon cannot arrange a placement. |
| Who It’s For | AIG describes fiduciary coverage for business executives and people or entities overseeing 401(k), pension and employee welfare plans. The page does not establish eligibility for every plan sponsor or plan type. 3Company-reported.

| Coverage Features | AIG says Fiduciary Edge addresses personal liability imposed on directors, officers and employees who oversee benefit plans and the sponsoring company. It describes certain penalty and compliance-program extensions subject to sublimits and policy terms. 3Company-reported. AIG’s public product description is not the policy. Actual entitlement depends on the applicable issued form, endorsements and declarations. | Aon lists Fiduciary coverage within the professional-services practice’s property-and-casualty coverages. The page does not describe covered fiduciary acts, plans, exclusions or policy terms. 6Company-reported. Aon’s marketing description of the brokerage/coverage area. The page is not the insurer’s policy form and does not establish an insured's entitlement to coverage. |

Confirm all sublimits and conditions in the quote and policy. 3Not publicly disclosed.

| Risk Services | AIG describes specialized underwriting and claims teams and lists the IRS Audit Protector program, settlor coverage and an ACA extension as product options.

The linked page describes company-reported support; specific account services and third-party arrangements must be confirmed. | Aon says its professional-services advisors use industry knowledge, insights, data and tools to support risk-management and human-capital decisions.
