[3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/fiduciary-liability "Fiduciary Liability Insurance") [6](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice")

## 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](https://www.aig.com/investor-relations "Investor Relations") [2](https://www.aig.com/home/risk-solutions/business "Business")

[AIG profile](https://spot.insure/insurance-providers/aig)

## 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.

## 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](https://www.dol.gov/sites/dolgov/files/ebsa/employers-and-advisers/guidance/field-assistance-bulletins/erisa-fidelity-bonding-requirements.pdf "Field Assistance Bulletin No. 2008-04: Guidance Regarding ERISA Fidelity Bonding Requirements") [8](https://asset.trvstatic.com/download/assets/fri-3001.pdf/c75b6c8e63ca11ee93454641efede6a9 "Fiduciary Liability") [9](https://www.travelers.com/business-insurance/professional-liability-insurance/fiduciary-liability "Fiduciary Liability Insurance")

## 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](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/fiduciary-liability "Fiduciary Liability Insurance") [6](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice")

### 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](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/fiduciary-liability "Fiduciary Liability Insurance") [6](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice")

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

[6](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Aon’s global professional-services practice page. This establishes a marketed brokerage/advisory offering, not policy issuance or account-specific placement..) |

[6](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Not found in reviewed sources; scope: Aon’s global practice page as reviewed 2026-09-30; no state-specific placement schedule or buyer quote was reviewed.

The page does not establish eligibility for every plan sponsor or plan type. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/fiduciary-liability "Fiduciary Liability Insurance") (Evidence: Company-reported; scope: Audience is the segment AIG names on the linked source; this is not an underwriting decision, quote or guarantee of availability..) | Aon identifies law, accounting and consulting firms as the audience for its global Professional Services Practice.

[3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/fiduciary-liability "Fiduciary Liability Insurance") (Evidence: Company-reported; scope: 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. [6](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: 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. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/fiduciary-liability "Fiduciary Liability Insurance") (Evidence: Not publicly disclosed; scope: This statement reports only what the linked public source discloses and does not substitute for a quote or issued policy..) | The reviewed page does not state a buyer-specific limit, retention, deductible or other placement terms. Confirm these in the quote, bond or issued policy. [6](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Not publicly disclosed; scope: Aon’s global practice page as reviewed 2026-09-30; no quote, bond form or issued policy was reviewed..) |
| 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. Availability and scope of each option must be confirmed in the issued form. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/fiduciary-liability "Fiduciary Liability Insurance") (Evidence: Company-reported; scope: 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. This is a company-described advisory service, not a claim outcome or policy benefit. [6](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Company-reported advisory services on Aon’s global practice page; account-specific service scope is not stated..) |

## AIG Reviews

Review Score: 4.4 / 10 from 2 rated sources, equally weighted.

Customer ratings for AIG are low: Trustpilot shows 1.9 out of 5 from 252 reviews, and NerdWallet gives 2.5 stars and notes more claims complaints than expected. These pages cover many AIG products and countries, so they only loosely describe business insurance.

- NerdWallet: NerdWallet editorial rating 2.5 (stars). NerdWallet’s editorial business-insurance comparison; the AIG entry concerns commercial liability and property insurance, not a quantified policyholder-review sample. The page’s complaint statement and 2.5-star editorial rating are source-specific and must not be recast as a consumer average. Checked 2026-09-29.

Review Score: 6.1 / 10 from 3 rated sources, equally weighted.

Public ratings for Aon are low: Trustpilot shows 1.2 out of 5 from 782 reviews, and BBB shows 1.6 from five. Aon is a global firm, so those pages mostly reflect other parts of the business, not large U.S. commercial accounts.
