Key Differences in D&O Insurance

Package category versus stated defense feature

THREE presents Directors & Officers as a category in its combined Business Owners Policy; its scope says the page does not establish that the category appears in every applicant’s quote. Marsh McLennan Agency’s D&O claim describes defense costs for alleged wrongful acts. A package buyer therefore needs to verify two different things in the quote: whether the THREE category is selected and what defense-cost wording appears in MMA’s proposed form. Neither marketing description substitutes for the declarations. 6 3

Package selection and policy-specific figures

THREE’s sample policy says the insurance summary lists limits and deductibles, while cautioning that the sample does not establish terms for a buyer’s quote or issued policy. MMA’s selected claim describes defense costs for wrongful acts. Those facts point to two documents to compare: verify that D&O is selected in THREE’s package, then read the actual declarations and defense-cost wording in each proposal. The sample issuer and sample terms should not be attributed to an individual THREE buyer. 5 3

What to Confirm in D&O Insurance Quotes

  • Ask THREE to confirm D&O appears in your BOP quote and request the buyer-specific declarations and limits. 6 5
  • Ask Marsh McLennan Agency to provide the limit, retention and defense-cost wording for its proposed D&O policy. 3
