Key Differences in Fiduciary Liability Insurance

Typical Grants Versus What the Policy Will Not Guarantee

Lockton and Marsh both broker fiduciary liability. Lockton says a typical policy covers breaches of benefit laws, plan-administration errors and omissions, voluntary compliance loss, and, when explicitly stated, certain HIPAA, Pension Protection Act and ACA fines. Marsh says a typical policy covers defense costs, damages, judgments and settlements from breach of duty or administration errors, but does not cover contractual liability, so it cannot guarantee a plan’s obligation to pay benefits due. 4 9

Lockton also distinguishes fiduciary liability from a legally required ERISA bond that insures plan assets against theft under crime/fidelity cover. Marsh’s reviewed FAQs do not make that bond contrast. 4 9

Who a Typical Policy Insures

Lockton lists the organization, the plans, employees, defined subsidiaries, spouses or domestic partners, estates and heirs, past employees kept as fiduciaries or consultants, and committees and trustees. Marsh lists the sponsor organization, the benefit plans, and plan fiduciaries who are directors, officers or employees of the sponsor. MMA also lists fiduciary in executive and professional liability. 4 9 10

Pre-Claim Counsel Versus Control Flags and Advocacy

Lockton’s Professional & Executive Risk Claims team integrates insurance and claims counsel so strategy exists before a claim. Marsh says FINPRO identifies red flags in fiduciary controls, builds programs from limit assessment through carrier selection, and assigns claims advocates from the outset. 4 9

What to Confirm in Fiduciary Liability Insurance Quotes

  • Ask Lockton whether HIPAA, ACA and Pension Protection Act fines are scheduled. 4
  • Ask Marsh how the contractual-liability exclusion would treat unpaid benefits. 9
  • Compare named insureds, including spouses, heirs and former-employee consultants Lockton lists. 4 9
  • Confirm you still have any required ERISA bond. 4
  • Ask whether the Marsh quote is FINPRO or MMA and which carrier each broker selected. 9 10 4
