## What Is Directors and Officers Insurance?

D&O insurance can help pay covered defense costs and losses from claims against company leaders over management decisions. If your organization has a board or executives, check whether the company itself is insured and whether legal bills reduce the limit. [8](https://www.thehartford.com/business-insurance/glossary-of-business-insurance-terms "Glossary of Business Insurance Terms") [9](https://eperils.com/wp-content/uploads/2016/09/14-02-18480.pdf "The Chubb Primary Directors & Officers and Entity Securities Liability Insurance") [10](https://asset.trvstatic.com/download/assets/pdo-3001.pdf/d66bd58e63c911ee99d14294a32ecb95 "Private Company Directors and Officers Liability Coverage")

## 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](https://global.lockton.com/us/en/products-services/d-and-o-insurance "D&O Insurance") [7](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

### 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](https://global.lockton.com/us/en/products-services/d-and-o-insurance "D&O Insurance") [7](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

## What Should You Confirm in Lockton and Marsh McLennan Agency D&O Insurance Quotes?

- Ask Lockton to mark Side A, B and C grants and entity coverage on the proposed form for your organization type. [4](https://global.lockton.com/us/en/products-services/d-and-o-insurance "D&O Insurance")
- Ask Marsh McLennan Agency to locate its defense-cost provisions and show which insureds and proceedings they address. [7](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")
