## 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

### A named fiduciary product versus a package inclusion

Markel identifies private companies, nonprofits, and employee-plan fiduciaries as its intended audience and describes claims involving mismanagement, administrative errors, and breach of duty. Liberty Mutual includes fiduciary coverage in ProShield for private and nonprofit organizations. Buyers should compare Markel’s stated plan-fiduciary audience with Liberty Mutual’s eligibility and package form. [3](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield") [6](https://www.markel.com/us/commercial/professional-and-management-liability/management-liability/private-and-nonprofit "Private and Nonprofit Management Liability Insurance")

### Claim costs and combined policy structure

Markel says covered claims may include defense costs, settlements, and judgments, subject to wording. Liberty Mutual describes fiduciary-duty protection and combines multiple management lines in one ProShield policy. Ask whether either proposal includes separate defense costs or shares limits across the package. [3](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield") [6](https://www.markel.com/us/commercial/professional-and-management-liability/management-liability/private-and-nonprofit "Private and Nonprofit Management Liability Insurance")

## What to Confirm in Fiduciary Liability Insurance Quotes

- Ask Markel for plan eligibility and whether defense erodes limits; ask Liberty Mutual for its defense-cost treatment and shared aggregate. [3](https://business.libertymutual.com/commercial-insurance-solutions/management-liability/proshield/ "ProShield") [6](https://www.markel.com/us/commercial/professional-and-management-liability/management-liability/private-and-nonprofit "Private and Nonprofit Management Liability Insurance")
