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. 8,9,10
Key Differences in Fiduciary Liability Insurance
Coverage Scope and Plan Details
Marsh McLennan Agency and Nationwide both list fiduciary liability within broader commercial or executive-liability offerings, but neither reviewed overview specifies plan-level coverage grants. Marsh McLennan Agency directs organizations to an adviser or specialist; Nationwide points prospects to an agent or quote request. For a plan sponsor, the shared high-level presentation means the policy wording carries the comparison: identify covered fiduciaries, plan types, and claims before treating either line listing as a match. 3 7
Placement and Buyer Questions
The public records also leave limits and insurer details to the quote. That is material where assets, participant counts, or plan administration sit across multiple entities. Ask both advisers to respond to the same plan schedule and show the issuer, aggregate, retention, and any sublimits side by side. 3 7
