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. 7,8,9
Key Differences in Fiduciary Liability Insurance
Specific Claim Description and Suite Listing
Markel describes fiduciary claims involving benefit-plan mismanagement, administrative errors or breach of fiduciary duty and says defense costs, settlements and judgments may be involved, subject to wording. Marsh McLennan Agency’s reviewed product page lists fiduciary liability within an executive and professional liability suite but does not state plan-specific coverage grants. A plan sponsor therefore has more published claim detail from Markel, while the MMA overview requires a direct discussion of the plan, insured roles and covered acts before the two options can be compared on terms. 3 6
Placement Route and Buyer Information
Marsh McLennan Agency invites organizations to contact an adviser or specialist about placement. Markel likewise invites customers or brokers to contact the company or underwriting team, but identifies private companies, nonprofits and plan-managing individuals as intended audiences. Both records leave the quote, insurer and policy form to be established directly; the buyer should provide plan assets, participants and plan types to each channel and request named carrier terms. 6 3
