Key Differences in D&O Insurance
Covered claims and defense
Markel describes D&O protection for organizational leaders facing covered mismanagement, breach-of-duty, or regulatory claims, including defense costs, settlements, and judgments. Marsh McLennan Agency describes coverage for alleged wrongful acts by directors or officers and mentions defense costs for civil and criminal actions and investigations. That gives buyers a more explicit description of proceedings in the MMA record; Markel’s summary names examples of alleged conduct and resolution costs. 3 6
Audience and placement
Markel lists private equity and portfolio companies, PEOs, healthcare, energy, education, and associations among its D&O audiences. MMA describes directors, officers, and their organizations and routes prospects to an adviser or specialist. Compare whether your organization fits Markel’s named sectors and ask MMA which insurer and form it would arrange; neither reviewed summary establishes universal terms. 3 6 6
