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. [9](https://www.thehartford.com/business-insurance/glossary-of-business-insurance-terms "Glossary of Business Insurance Terms") [10](https://eperils.com/wp-content/uploads/2016/09/14-02-18480.pdf "The Chubb Primary Directors & Officers and Entity Securities Liability Insurance") [11](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 USI Insurance Services D&O Insurance?

### Claim types and defense protection

USI describes D&O as protection for company leadership against personal loss and lists breach of contract, breach of duty, misrepresentation, securities and creditor lawsuits among common claim types. Marsh McLennan Agency’s claim describes defense costs for alleged wrongful acts. A company comparing these descriptions can use one concrete allegation, such as a creditor claim, and ask both providers how insured persons, defense expense and applicable exclusions appear in the proposed policy. [7](https://www.usi.com/executive-insights/executive-series-articles/supplemental/emerging-business/q3-2023/protect-against-management-liability-risks/ "Protect Your Company and Personal Assets From Management Liability Risks") [3](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

### ExecuSafe wording and defense expense

USI says it can place D&O through its named ExecuSafe endorsement package and describes several management-liability claim examples. MMA’s selected claim names defense costs for D&O wrongful acts. Ask USI to show the ExecuSafe endorsement that applies to the chosen carrier form, and ask MMA to identify the defense-cost grant in its proposal. This keeps the review on policy terms rather than assuming a package name guarantees a specific structure. [7](https://www.usi.com/executive-insights/executive-series-articles/supplemental/emerging-business/q3-2023/protect-against-management-liability-risks/ "Protect Your Company and Personal Assets From Management Liability Risks") [3](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

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

- Ask USI to document each gap it finds and identify the relevant ExecuSafe endorsement language. [7](https://www.usi.com/executive-insights/executive-series-articles/supplemental/emerging-business/q3-2023/protect-against-management-liability-risks/ "Protect Your Company and Personal Assets From Management Liability Risks")
- Ask Marsh McLennan Agency to map the same creditor or securities scenario to its defense-cost wording. [3](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA")

This is not a policy form or a universal eligibility statement..) | USI is a broker for D&O coverage. It says it helps clients identify D&O exposures, review any existing management liability policies for gaps, and place coverage, including through its own named endorsement package, ExecuSafe. [7](https://www.usi.com/executive-insights/executive-series-articles/supplemental/emerging-business/q3-2023/protect-against-management-liability-risks/ "Protect Your Company and Personal Assets From Management Liability Risks") (Evidence: Company-reported; scope: ExecuSafe article's "How USI Can Help" section..) |
| Issuing Insurer | Confirm in your quote. | USI does not name the insurer that underwrites ExecuSafe or other D&O placements on the pages reviewed; it describes ExecuSafe as an endorsement package it applies to policies placed with the market. [7](https://www.usi.com/executive-insights/executive-series-articles/supplemental/emerging-business/q3-2023/protect-against-management-liability-risks/ "Protect Your Company and Personal Assets From Management Liability Risks") (Evidence: Not publicly disclosed; scope: ExecuSafe article and Technology/Business Services practice pages as read on 2026-09-23..) |

This is not a policy form or a universal eligibility statement..) | USI targets small- and medium-sized businesses for ExecuSafe, saying many either skip D&O coverage or buy insufficient limits because their brokers do not help them identify the exposure. Its Technology practice separately places D&O for software, hardware and communications clients from seed stage through IPO.

| Coverage Features | The cited product page describes D&O for alleged wrongful acts by directors or officers, including described defense costs for civil and criminal actions and investigations. Marketing description only; actual coverage, exclusions, conditions, limits, and availability depend on the issued policy and jurisdiction. [3](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA") (Evidence: Company-reported; scope: directors officers marketed by marsh-mclennan-agency; scope is limited to the cited official product overview and described audience. This is not a policy form or a universal eligibility statement..) | USI says D&O insurance is meant to protect a company's leadership from personal loss in a lawsuit, since the corporate veil does not shield directors and officers from personal liability for the business's actions and debts. It lists breach of contract, breach of duty, misrepresentation, unfair competition, misappropriation of trade secrets, securities lawsuits and creditor lawsuits as common claim types the coverage responds to. [7](https://www.usi.com/executive-insights/executive-series-articles/supplemental/emerging-business/q3-2023/protect-against-management-liability-risks/ "Protect Your Company and Personal Assets From Management Liability Risks") (Evidence: Company-reported; scope: ExecuSafe article's description of D&O purpose and claim types; actual insuring agreements and exclusions are set by the issued policy..) |
| Limits and Retentions | The cited overview does not set a universal limit or retention for this line. Ask for the proposed policy form, limits, retentions, exclusions, and conditions in the quote. [3](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Executive and Professional Liability | MMA") (Evidence: Not publicly disclosed; scope: Only the cited marketing page was reviewed for published limit and retention information; no policy-form entitlement is inferred..) | USI cites a 2016 Chubb survey that found 43% of private companies carry no D&O coverage, with an average private-company D&O claim cost of $450,000, but the article does not publish USI's own placed limits, retentions or premium ranges for ExecuSafe. [7](https://www.usi.com/executive-insights/executive-series-articles/supplemental/emerging-business/q3-2023/protect-against-management-liability-risks/ "Protect Your Company and Personal Assets From Management Liability Risks") (Evidence: Not publicly disclosed; scope: Third-party statistic cited by USI to illustrate exposure, not USI's own placement data..) |
| Risk Services | Confirm in your quote. | USI's Technology practice cites a case study where its benchmarking analysis showed a software company was buying more D&O limit than peers with similar risk profiles, and says the resulting change saved the client more than $100,000 per year in D&O premium. [5](https://www.usi.com/property-casualty/technology/ "Technology Insurance") (Evidence: Company-reported; scope: Single case study on the Technology practice page; company-reported outcome, not independently verified..) |
| How to Apply | The page invites organizations to contact a Marsh McLennan Agency adviser or specialist to discuss placement. The page does not establish a quote, bind, or coverage-effective timeline.
