## 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 Cowbell and Marsh McLennan Agency D&O Insurance?

### Eligibility and underwriting role

Cowbell targets its Private Company D&O module at private companies with fewer than 250 employees and under $50 million in assets, in sectors including technology, construction and manufacturing. Zurich underwrites the module. MMA describes arranging D&O coverage for corporate executives, board members and their organizations, with eligibility and terms set by placement. Ask Cowbell whether your company fits those thresholds and MMA which insurers match your size and industry. [4](https://cowbell.insure/mgmt-liability/ "Management liability coverage for small & medium enterprises") [7](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

### Who can access the product

Cowbell’s D&O module is accessed only by appointed Zurich E&S wholesalers through its platform API, not sold directly to businesses. MMA’s product page invites organizations to contact an adviser or specialist. That makes the initial channel materially different for a buyer: ask Cowbell who can submit the risk and ask MMA which adviser will lead the application. [4](https://cowbell.insure/mgmt-liability/ "Management liability coverage for small & medium enterprises") [7](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

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

- Ask Cowbell whether your employee count and assets fit the module and which appointed wholesaler can submit it. [4](https://cowbell.insure/mgmt-liability/ "Management liability coverage for small & medium enterprises")
- Ask MMA which underwriters it will approach and how its proposed D&O coverage protects both leaders and the company. [7](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

| Risk Services | Cowbell frames D&O coverage as a way to help attract and retain directors and officers by giving them personal-asset protection, and says the product covers legal fees, settlements, and other defense costs for the company and its management.
