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. 9,10,11
Key Differences in Fiduciary Liability Insurance
Broker review versus a combined insurer product
USI brokers fiduciary coverage individually or reviews it inside a management-liability program through ExecuSafe; its services include claim advocacy and gap review. Liberty Mutual offers fiduciary liability through ProShield’s combined package. Buyers can compare USI’s review of an existing policy with Liberty Mutual’s terms for a replacement or package. 3 7
Line review versus stated coverage scope
USI specifically says ExecuSafe reviews existing fiduciary coverage for gaps, while Liberty Mutual describes fiduciary-duty protection and selected defense and compliance features in ProShield. Buyers should use the policy review to compare gaps against the new package wording, not just the coverage labels. 3 7
