## 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

Chubb underwrites fiduciary liability through ForeFront Portfolio 3.0 for private companies, their fiduciaries, and benefit plans. Aon describes arranging or advising on fiduciary coverage through its Professional Services Practice for law, accounting, and consulting firms. The distinction is direct underwriting versus broker placement; buyers should establish whether their plan sponsor qualifies for Chubb and which insurer Aon would approach. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](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.")

### Coverage Terms and Service

Chubb lists allegations involving benefit denial, plan administration, prohibited transactions, conflicts, and imprudent investment or service-provider choices, and says the company, executives, employees, and plan are insured. Aon’s overview does not specify covered acts or insured parties. These details matter for identifying the people and entities that need protection; compare the definitions and exclusions in each proposed form. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](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.")

## What to Confirm in Fiduciary Liability Insurance Quotes

- Ask Chubb which ForeFront options are included and ask Aon to identify the issuing carrier. Both quotes should list insured entities, plans, limits, and exclusions. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [7](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.")
