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-review support

Aon describes fiduciary liability within a global professional-services brokerage practice and says its advisors use industry knowledge, data, and tools for risk and human-capital decisions. USI says it brokers the line and reviews existing fiduciary coverage for gaps through ExecuSafe. A buyer reviewing a current management-liability program can ask USI specifically for that gap review; Aon’s published description is broader advisory support. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://www.usi.com/property-casualty/business-services/ "Business Services")

### A named coverage discussion versus a practice listing

Aon lists fiduciary liability but does not explain which plan acts or terms its placements cover. USI describes protection against claims of employee-benefit-plan mismanagement and says it may place the coverage individually or review it in a management-liability program. Neither description names a carrier or states limits, so the quote and policy need to settle those specifics. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://www.usi.com/property-casualty/business-services/ "Business Services")

## What to Confirm in Fiduciary Liability Insurance Quotes

- Ask USI whether ExecuSafe will review your current fiduciary form and request the gap findings in writing; ask Aon what account-level advisory work is included. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://www.usi.com/property-casualty/business-services/ "Business Services")
- Have both brokers identify the insurer, fiduciary limit, retention, and covered plan types before comparing proposals. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](https://www.usi.com/property-casualty/business-services/ "Business Services")

## Offering Details

| Criteria | Aon Fiduciary Liability brokerage and risk-advisory offering | USI Fiduciary Liability Brokerage |
| --- | --- | --- |
| 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..) | USI brokers fiduciary liability coverage, which protects a company and its plan fiduciaries against claims of mismanaging an employee benefit plan; USI places it individually or reviews it as part of a management liability program under its ExecuSafe endorsement package. [7](https://www.usi.com/property-casualty/business-services/ "Business Services") [8](https://www.usi.com/executive-insights/executive-series-articles/supplemental/emerging-business/q3-2023/protect-against-management-liability-risks/ "Protect Your Company and Personal Assets From Management Liability Risks") (Evidence: Company-reported; scope: Business Services catalogue and ExecuSafe article..) |
| 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..) | Neither page names the insurer USI uses for fiduciary liability placements. [7](https://www.usi.com/property-casualty/business-services/ "Business Services") (Evidence: Not publicly disclosed; scope: Pages as read on 2026-09-23..) |
| 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..) | USI's Business Services practice targets building and maintenance, repair service, janitorial, staffing and printing companies for its broader coverage catalogue, which includes fiduciary liability; the ExecuSafe article separately targets small- and medium-sized businesses generally for management liability review. [7](https://www.usi.com/property-casualty/business-services/ "Business Services") [8](https://www.usi.com/executive-insights/executive-series-articles/supplemental/emerging-business/q3-2023/protect-against-management-liability-risks/ "Protect Your Company and Personal Assets From Management Liability Risks") (Evidence: Company-reported; scope: Company description of client segments for each source..) |
| 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..) | USI lists fiduciary liability among the coverages it places for business-services clients, and separately says its ExecuSafe review looks for gaps in a client's existing fiduciary liability coverage as part of a management liability review. [7](https://www.usi.com/property-casualty/business-services/ "Business Services") [8](https://www.usi.com/executive-insights/executive-series-articles/supplemental/emerging-business/q3-2023/protect-against-management-liability-risks/ "Protect Your Company and Personal Assets From Management Liability Risks") (Evidence: Company-reported; scope: Catalogue listing plus the ExecuSafe review description; actual insuring agreements and exclusions are set by the issued policy..) |
| 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..) | Neither page publishes fiduciary liability limit or retention figures. [7](https://www.usi.com/property-casualty/business-services/ "Business Services") (Evidence: Not publicly disclosed; scope: Pages as read on 2026-09-23..) |
| 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..) | USI's Business Services practice says it offers classification and exposure reviews, claim advocacy and risk control across its coverage lines, including fiduciary liability, and its ExecuSafe process specifically reviews existing fiduciary liability policies for coverage gaps. [7](https://www.usi.com/property-casualty/business-services/ "Business Services") [8](https://www.usi.com/executive-insights/executive-series-articles/supplemental/emerging-business/q3-2023/protect-against-management-liability-risks/ "Protect Your Company and Personal Assets From Management Liability Risks") (Evidence: Company-reported; scope: Combines the general Business Services service list with the ExecuSafe-specific review step..) |
| How to Apply | Confirm in your quote. | USI directs business-services inquiries to pcinquiries@usi.com or a local office, and ExecuSafe/management-liability inquiries to Select.Business@usi.com.
