Key Differences in Fiduciary Liability Insurance
Broker placement with claims counsel versus package underwriting
Lockton places fiduciary liability with insurers and says its claims team integrates claims counsel into the broking team before a claim. Liberty Mutual packages fiduciary liability in ProShield. Buyers should compare the broker’s pre-claim planning service with the specific claims process and combined limits in Liberty Mutual’s policy. 3 7
Typical coverage terms versus selected package features
Lockton describes typical coverage for benefit-law breaches, plan-administration errors, voluntary compliance losses, and certain fines when expressly included. Liberty Mutual lists fiduciary-duty protection and selected defense and compliance features, with exact terms in the policy. Compare each form’s penalties and voluntary-correction provisions. 3 7
