Nationwide’s commercial catalogue includes common small-business policies and separate specialty products. A catalogue listing does not establish eligibility or policy terms; confirm the issuing company and coverage for your state and business.

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 Marsh McLennan Agency and Nationwide D&O Insurance? ### Alleged management decisions and defense costs Nationwide describes D&O for claims tied to alleged decisions or wrongful acts by company directors and officers, subject to policy terms. Marsh McLennan Agency’s overview also centers on alleged wrongful acts, with defense costs specifically named for civil and criminal actions. The overlap is useful: both descriptions start with management conduct, while MMA’s claim identifies cost categories. Ask both providers to show how the quoted form connects the alleged act, covered insureds and defense expense. [7](https://www.nationwide.com/business/insurance/management-liability-specialty/products/commercial-liability/types/directors-and-officers-liability "Directors and Officers Liability") [3](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA") ### Testing a real claim scenario For a claim alleging that a board decision caused investor loss, put Nationwide’s management-decision description beside MMA’s stated defense-cost feature. Ask each provider to identify the trigger, insured persons, retention and any shared-limit treatment in the actual wording. Nationwide frames the covered subject generally; MMA names defense costs for wrongful-act claims. The issued form, rather than either marketing summary, determines how that scenario is treated.

[7](https://www.nationwide.com/business/insurance/management-liability-specialty/products/commercial-liability/types/directors-and-officers-liability "Directors and Officers Liability") - Ask Marsh McLennan Agency to show the proposed civil and criminal defense-cost wording and applicable retention.
