## 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. [9](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") [10](https://asset.trvstatic.com/download/assets/fri-3001.pdf/c75b6c8e63ca11ee93454641efede6a9 "Fiduciary Liability") [11](https://www.travelers.com/business-insurance/professional-liability-insurance/fiduciary-liability "Fiduciary Liability Insurance")

## Key Differences in Fiduciary Liability Insurance

### Placement and Plan Fit

Gallagher places fiduciary liability through outside carriers and advises on limits for corporations sponsoring retirement or welfare plans. Aon describes fiduciary as a line its Professional Services Practice helps arrange or advise on for law, accounting, and consulting firms. Buyers should ask both brokers which insurers can quote their plan and who will recommend the limit; neither brokerage itself is the issuing carrier. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [6](https://www.ajg.com/insurance/executive-and-financial-risk-insurance/ "Executive and Financial Risk Insurance")

### Published Coverage and Services

Gallagher describes coverage for ERISA fiduciaries, committees, and personnel designing or implementing 401(k) or pension plans, and says proprietary models help measure risk and select limits. Aon describes broader risk-management and human-capital advice but does not specify fiduciary roles or models on its page. A plan sponsor can compare the analysis process while reviewing the actual carrier wording separately. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [6](https://www.ajg.com/insurance/executive-and-financial-risk-insurance/ "Executive and Financial Risk Insurance")

## What to Confirm in Fiduciary Liability Insurance Quotes

- Ask Gallagher what plan and asset data inform its limit model. Ask Aon which plan fiduciaries are insured, what limit it recommends, and which insurer will issue the policy. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [6](https://www.ajg.com/insurance/executive-and-financial-risk-insurance/ "Executive and Financial Risk Insurance")

## Offering Details

| Criteria | Aon Fiduciary Liability brokerage and risk-advisory offering | Gallagher Fiduciary Liability Insurance |
| --- | --- | --- |
| Role in This Line | 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. [3](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..) | Gallagher's Executive and Financial Risk practice places fiduciary liability coverage with outside carriers and advises on limits; it does not underwrite the policy. [6](https://www.ajg.com/insurance/executive-and-financial-risk-insurance/ "Executive and Financial Risk Insurance") (Evidence: Company-reported; scope: Group-level executive-and-financial-risk practice page..) |
| Issuing Insurer | The reviewed practice page does not name the insurer or producing legal entity for a specific placement. Ask for both on the quote and binder. [3](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. This does not establish that Aon cannot arrange a placement..) | The executive-and-financial-risk page does not name the insurer that would issue a given client's fiduciary liability policy. [6](https://www.ajg.com/insurance/executive-and-financial-risk-insurance/ "Executive and Financial Risk Insurance") (Evidence: Not publicly disclosed; scope: Checked the group-level executive-and-financial-risk practice page..) |
| Who It’s For | Aon identifies law, accounting and consulting firms as the audience for its global Professional Services Practice. That audience scope does not establish eligibility for every firm or other business. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Audience described for Aon’s global professional-services practice. It does not establish U.S. state availability or underwriting eligibility for a placement..) | Gallagher targets this coverage at corporations sponsoring retirement or welfare benefit plans, since the described exposure is tied specifically to ERISA fiduciary duties. [6](https://www.ajg.com/insurance/executive-and-financial-risk-insurance/ "Executive and Financial Risk Insurance") (Evidence: Company-reported; scope: Group-level executive-and-financial-risk practice page..) |
| Coverage Features | 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. [3](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..) | Gallagher describes fiduciary liability as protecting a corporation's Employee Retirement Income Security Act (ERISA) fiduciaries, fiduciary committees and personnel who design or implement 401(k) or pension plans for employees and retirees. [6](https://www.ajg.com/insurance/executive-and-financial-risk-insurance/ "Executive and Financial Risk Insurance") (Evidence: Company-reported; scope: Group-level executive-and-financial-risk practice page; a service description, not a specific policy's insuring agreement or exclusions..) |
| Limits and Retentions | 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. [3](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..) | The page does not publish specific fiduciary liability limits or premium ranges beyond describing its proprietary limit-selection models. [6](https://www.ajg.com/insurance/executive-and-financial-risk-insurance/ "Executive and Financial Risk Insurance") (Evidence: Not publicly disclosed; scope: Checked the group-level executive-and-financial-risk practice page..) |
| Risk Services | 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. [3](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..) | Gallagher says it has proprietary models to measure fiduciary risk and assist clients in selecting coverage limits. [6](https://www.ajg.com/insurance/executive-and-financial-risk-insurance/ "Executive and Financial Risk Insurance") (Evidence: Company-reported; scope: Group-level executive-and-financial-risk practice page..) |
