[3](https://www.markel.com/us/commercial/professional-and-management-liability/management-liability/private-and-nonprofit "Private and Nonprofit Management Liability Insurance") [7](https://www.nationwide.com/business/insurance/management-liability-specialty/products/commercial-liability/ "Commercial Liability Products | Nationwide")

## What Is Nationwide?

## 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. [8](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") [9](https://asset.trvstatic.com/download/assets/fri-3001.pdf/c75b6c8e63ca11ee93454641efede6a9 "Fiduciary Liability") [10](https://www.travelers.com/business-insurance/professional-liability-insurance/fiduciary-liability "Fiduciary Liability Insurance")

## Key Differences in Fiduciary Liability Insurance

### Available Public Coverage Detail

Markel’s product description names benefit-plan mismanagement, administrative errors and breach of fiduciary duty, with defense costs, settlements and judgments subject to policy wording. Nationwide’s reviewed overview identifies fiduciary liability as a commercial offering but does not specify plan-level grants or eligible plan types. The difference is how much can be assessed before requesting terms: use Markel’s named allegations as prompts, then ask Nationwide to provide the exact coverage form and identify which plan decisions and fiduciaries it addresses. [3](https://www.markel.com/us/commercial/professional-and-management-liability/management-liability/private-and-nonprofit "Private and Nonprofit Management Liability Insurance") [7](https://www.nationwide.com/business/insurance/management-liability-specialty/products/commercial-liability/ "Commercial Liability Products | Nationwide")

### Eligibility and Quote Access

Nationwide describes its audience as commercial organizations considering management-liability products and directs them to contact an agent or request a quote. Markel names private companies, nonprofits and individuals managing benefit plans and invites contact with the company or underwriting team. Neither reviewed claim sets a universal plan threshold, so sponsors should confirm insurer appetite using participant counts, plan assets and plan types rather than infer fit from the broad product listing. [7](https://www.nationwide.com/business/insurance/management-liability-specialty/products/commercial-liability/ "Commercial Liability Products | Nationwide") [3](https://www.markel.com/us/commercial/professional-and-management-liability/management-liability/private-and-nonprofit "Private and Nonprofit Management Liability Insurance")
