Key Differences in D&O Insurance
Terms that matter before a claim
Liberty Mutual’s ProShield overview specifically mentions investigation and pre-claim inquiry coverage. Markel describes D&O protection for leaders against claims such as mismanagement, breach of duty or regulatory violations, including defense costs, settlements and judgments subject to policy terms. For a buyer concerned about an inquiry before a formal claim, that difference calls for close wording review: Markel’s overview does not specify that pre-claim stage. 3 6
Placement and coverage structure
Markel lists D&O as standalone or blended within management liability for private companies and nonprofits, with named customer types including private-equity portfolio companies, PEOs, hospitality, energy and healthcare. Liberty Mutual presents a management-liability package with separate private-company and not-for-profit options. Buyers should confirm which form matches their sector and whether standalone placement or package structure changes the other coverage parts. 6 6 3
