What Are the Key Differences Between Marsh McLennan Agency and THREE by Berkshire Hathaway Professional Liability (E&O) Insurance?

Which Professional Work Is Named

THREE’s sample policy names Berkshire Hathaway Direct Insurance Company as issuer, while MMA’s overview describes arranging placement and does not identify a universal insurer. Ask whether E&O appears in the actual THREE quote and declarations; MMA buyers should confirm the insurer for their placement. [6] [1]

Placement Scope and Buying Route

THREE directs small businesses to an online quote and offers licensed Small Business Advisors to help. MMA invites organizations to speak with an adviser or specialist about professional placement, so the initial route differs even though both require a quote to establish terms. [6] [2]

What Should You Confirm in Marsh McLennan Agency and THREE by Berkshire Hathaway Professional Liability (E&O) Insurance Quotes?

  • Does the THREE quote include E&O for your profession, and what limits and exclusions appear in its declarations? [1]
  • Which MMA professional line and insurer would be proposed, and would coverage be standalone or part of a package? [6]
