What Are the Key Differences Between Lockton and Marsh McLennan Agency D&O Insurance?
Entity and individual coverage parts
Lockton describes Side A as direct protection for individual directors and officers when the company cannot indemnify them, Side B as company reimbursement after indemnification, and Side C as entity coverage. Marsh McLennan Agency’s selected D&O claim names defense costs for alleged wrongful acts. For a buyer comparing program architecture with a stated cost feature, the key is to request the actual grants side by side rather than infer that a marketing description contains every part. 4 7
How company type affects the structure
Lockton says Side C is generally limited to securities claims for public companies but broader for private and nonprofit organizations; it presents this as an educational structure, not a specimen form. Marsh McLennan Agency describes D&O defense costs for civil and criminal actions and investigations. A private company and a public issuer should ask how entity coverage differs in the proposed policy and where defense costs sit in relation to each coverage part. 4 7
