## 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

### Coverage Details and Plan Fit

Chubb underwrites Fiduciary Liability through ForeFront Portfolio 3.0 and lists covered allegations such as benefit denial, plan-administration errors, prohibited transactions, conflicts, and imprudent investment or service-provider decisions. It identifies the company, executives, employees, and benefit plan as insureds. Marsh McLennan Agency names fiduciary liability in its executive and professional suite, but its overview does not enumerate plan-specific grants or insured parties. For sponsors comparing a named policy form with broker placement, ask who is insured and how each plan duty is addressed. [4](https://www.chubb.com/us-en/business-insurance/forefront-portfolio-3-0-fiduciary-liability-insurance.html "ForeFront Portfolio 3.0: Fiduciary Liability Insurance in the U.S.") [8](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

### Placement and Buyer Questions

Chubb also describes loss-prevention resources and says agents and brokers can quote ForeFront through Chubb Marketplace. Marsh McLennan Agency asks prospects to contact an adviser. The route differs, while both still require confirmation of the actual insurer commitment, limits, and exclusions. [5](https://www.chubb.com/us-en/business-insurance/forefront.html "The ForeFront Portfolio") [8](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

## What to Confirm in Fiduciary Liability Insurance Quotes

- Ask Chubb whether ForeFront will cover the plan and all named insureds, and request the limits and exclusions for investment and service-provider allegations. [4](https://www.chubb.com/us-en/business-insurance/forefront-portfolio-3-0-fiduciary-liability-insurance.html "ForeFront Portfolio 3.0: Fiduciary Liability Insurance in the U.S.")
