## 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

### Broker review versus a combined insurer product

USI brokers fiduciary coverage individually or reviews it inside a management-liability program through ExecuSafe; its services include claim advocacy and gap review. Liberty Mutual offers fiduciary liability through ProShield’s combined package. Buyers can compare USI’s review of an existing policy with Liberty Mutual’s terms for a replacement or package. [3](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield") [7](https://www.usi.com/property-casualty/business-services/ "Business Services")

### Line review versus stated coverage scope

USI specifically says ExecuSafe reviews existing fiduciary coverage for gaps, while Liberty Mutual describes fiduciary-duty protection and selected defense and compliance features in ProShield. Buyers should use the policy review to compare gaps against the new package wording, not just the coverage labels. [3](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield") [7](https://www.usi.com/property-casualty/business-services/ "Business Services")

## What to Confirm in Fiduciary Liability Insurance Quotes

- Ask USI to identify uncovered plan scenarios and carrier terms; ask Liberty Mutual how ProShield addresses those gaps and allocates limits. [3](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield") [7](https://www.usi.com/property-casualty/business-services/ "Business Services")

## Offering Details

| Criteria | Liberty Mutual ProShield Fiduciary Liability | USI Fiduciary Liability Brokerage |
| --- | --- | --- |
| Role in This Line | Liberty Mutual includes fiduciary liability in its ProShield management-liability package. [3](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield") (Evidence: Company-reported; scope: Liberty Mutual’s cited product or program overview documents this description. It does not establish the issuing insurer for an individual quote, exact state or provincial availability, the policy form, complete exclusions, or terms offered to a particular buyer; confirm those in the quote and policy documents..) | 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.

It does not establish the issuing insurer for an individual quote, exact state or provincial availability, the policy form, complete exclusions, or terms offered to a particular buyer; confirm those in the quote and policy documents..) | 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 | The page describes protection for fiduciaries, benefit plans and sponsors against fiduciary-duty exposures and lists selected defense-cost and compliance features; the policy form determines terms.

It does not establish the issuing insurer for an individual quote, exact state or provincial availability, the policy form, complete exclusions, or terms offered to a particular buyer; confirm those in the quote and policy documents..) | 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.

| Limits and Retentions | The cited public overview does not establish the limits, deductibles, exclusions or form terms that would apply to a specific buyer. [3](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield") (Evidence: Not publicly disclosed; scope: Ask for the quote and specimen or issued policy forms before treating a listed feature as covered..) | 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 | Liberty Mutual describes ProShield as one package policy that combines multiple management-liability coverages and is designed to reduce the need for separate endorsements. [3](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield") (Evidence: Company-reported; scope: Liberty Mutual’s cited product or program overview documents this description. It does not establish the issuing insurer for an individual quote, exact state or provincial availability, the policy form, complete exclusions, or terms offered to a particular buyer; confirm those in the quote and policy documents..) | 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..) |
