## 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.
