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. 10,11,12
Key Differences in Fiduciary Liability Insurance
A brokerage program versus a carrier package
Marsh’s FINPRO practice places fiduciary coverage for plan sponsors and fiduciaries, helping assess limits, select carriers, and advocate on claims. Liberty Mutual includes fiduciary liability in ProShield’s combined package. Buyers should compare Marsh’s carrier and limit selection process with the exact lines and limits bundled into ProShield. 3 8
Coverage for plan administration and contractual duties
Marsh describes typical defense, damages, judgments, and settlements for fiduciary breach or plan-administration errors, but says the policy does not guarantee contractual benefit obligations. Liberty Mutual describes fiduciary-duty protection with terms controlled by its form. Check both against benefit commitments and plan-administration risks. 3 8
