Key Differences in Fiduciary Liability Insurance

Product Detail and Policy Terms

Marsh McLennan Agency lists fiduciary liability as a named product in its executive and professional liability suite, but says the overview does not state plan-specific grants. AIG describes protection for people overseeing 401(k), pension and welfare plans and names certain compliance extensions. Buyers need to compare the issued wording because MMA’s overview gives little detail about covered plan events while AIG identifies features whose availability still depends on the policy. 3 6

How Buyers Start a Placement

Marsh McLennan Agency directs prospects to an adviser or specialist to discuss placement. AIG describes specialized underwriting and claims teams. Neither source establishes how quickly a particular account will be quoted or which staff will handle it; ask MMA for the proposed carrier and form, and AIG for the issuing entity and selected options. 3 6
