[5](https://www.marsh.com/en/services/financial-professional-liability/expertise/directors-and-officers-liability.html "Directors and Officers Liability (D&O)") [9](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [8](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway")

## 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. [10](https://www.thehartford.com/business-insurance/glossary-of-business-insurance-terms "Glossary of Business Insurance Terms") [11](https://eperils.com/wp-content/uploads/2016/09/14-02-18480.pdf "The Chubb Primary Directors & Officers and Entity Securities Liability Insurance") [12](https://asset.trvstatic.com/download/assets/pdo-3001.pdf/d66bd58e63c911ee99d14294a32ecb95 "Private Company Directors and Officers Liability Coverage")

## What Are the Key Differences Between Marsh and THREE by Berkshire Hathaway D&O Insurance?

### Marsh Frames Common Risks by Organization Type

Marsh says public-company leaders commonly face securities suits from shareholders and regulators, while private and nonprofit organizations more often encounter employment-practices claims; it also names cyber-related liability as a possible exposure across organization types. This is Marsh's educational description of typical exposures, not a policy promise. THREE markets D&O in its BOP, but the category alone does not establish whether a particular quote will respond to these allegations. Use your company's likely claimants to ask Marsh how a placement addresses them and ask THREE for the D&O wording that would apply. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/directors-and-officers-liability.html "Directors and Officers Liability (D&O)") [9](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway")

### Marsh Outlines the Side A/B/C Structure

Marsh explains Side A for directors and officers when the organization cannot or will not indemnify them, Side B reimbursement to the organization, and Side C entity protection that is generally limited to securities claims for public companies. THREE's marketed category confirms that its product page lists D&O, but the listing alone does not establish response in a buyer's policy. For a public company weighing securities exposure, request Marsh's proposed form and ask THREE which D&O grants, entity limits, and exclusions appear in its quote. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/directors-and-officers-liability.html "Directors and Officers Liability (D&O)") [9](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway")

## What Should You Confirm in Marsh and THREE by Berkshire Hathaway D&O Insurance Quotes?

- For Marsh, identify the form, Side A/B/C limits, and how it treats securities, employment, and cyber-related allegations. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/directors-and-officers-liability.html "Directors and Officers Liability (D&O)")
- For THREE, confirm D&O is offered and request its coverage parts, entity terms, exclusions, limit, and retention. [9](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [8](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway")

## Marsh vs THREE by Berkshire Hathaway D&O Insurance Compared

| Criteria | Marsh Directors and Officers Liability (D&O) Insurance | THREE Business Owners Policy |
| --- | --- | --- |
| Role in This Line | Marsh's financial and professional liability practice places D&O insurance for public, private and non-profit companies; MMA also places D&O coverage within its executive and professional liability practice for middle-market clients. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/directors-and-officers-liability.html "Directors and Officers Liability (D&O)") [6](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Expert Executive and Professional Liability Insurance") (Evidence: Company-reported; scope: Marsh D&O page and MMA executive and professional liability page..) | THREE presents Directors and Officers as a component of its combined Business Owners Policy rather than identifying it as a separate standalone policy on the reviewed product page. [9](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: Company-described U.S. package structure. The page does not establish underwriting terms or that every listed category will be included for every applicant..) |
| Issuing Insurer | The reviewed pages do not name a specific D&O insurer. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/directors-and-officers-liability.html "Directors and Officers Liability (D&O)") [6](https://www.marshmma.com/us/solutions/executive-and-professional-liability.html "Expert Executive and Professional Liability Insurance") (Evidence: Not publicly disclosed; scope: Marsh D&O page and MMA executive and professional liability page as read on 2026-09-23..) | The linked sample policy's declarations identify Berkshire Hathaway Direct Insurance Company as issuer. [8](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: This is the issuer named on the public sample only; the sample does not establish the issuing entity for every state-specific quote or buyer's issued policy..) |
| Who It’s For | Marsh says public company directors and officers typically face more securities-lawsuit exposure from shareholders and regulators, while private and non-profit organizations more often face employment-practices claims from customers, vendors or regulators; directors and officers of all organization types can face cyber-related liability exposure. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/directors-and-officers-liability.html "Directors and Officers Liability (D&O)") (Evidence: Company-reported; scope: Marsh D&O page, common risks FAQ..) | The reviewed product page does not state separate eligibility rules for Directors and Officers; the general quote and advisor route is not proof that a particular business qualifies for it. [9](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [7](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway") (Evidence: Not publicly disclosed; scope: Eligibility and state availability remain unestablished for an individual risk until THREE returns its quote and applicable forms..) |
| Coverage Features | Marsh says D&O insurance typically has three coverage sides: Side A protects directors' and officers' personal assets when the organization cannot or will not indemnify them; Side B reimburses the organization for indemnifying directors and officers; Side C offers balance-sheet protection when the entity itself is named, generally limited to securities claims for public companies. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/directors-and-officers-liability.html "Directors and Officers Liability (D&O)") (Evidence: Company-reported; scope: Marsh D&O page FAQ; illustrative policy structure, not a specific policy form..)<br><br>Marsh says ESG-related stakeholder scrutiny, covering areas such as carbon emissions, renewable-energy use, labor practices, board diversity and executive compensation, can add regulatory, legislative or litigation pressure on directors and officers beyond traditional D&O exposures. [5](https://www.marsh.com/en/services/financial-professional-liability/expertise/directors-and-officers-liability.html "Directors and Officers Liability (D&O)") (Evidence: Company-reported; scope: Marsh D&O page, What other risks do directors and officers face? section..) | THREE's Business Owners Policy page lists Directors & Officers among its marketed coverage categories in the combined policy. This describes the product page, not whether the category appears in a particular quote or responds to a loss. [9](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [8](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: Official THREE package marketing for Directors and Officers. The sample policy is state-selectable and does not establish that this item is included in every quote or issued policy..) |
| Limits and Retentions | Confirm in your quote. | The reviewed public product page does not state a separate limit or deductible for Directors and Officers; THREE says the quote-specific insurance summary lists limits and deductibles. [9](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [8](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") (Evidence: Not publicly disclosed; scope: No number is inferred from the sample policy. The quote and issued declarations control the buyer-specific limit and deductible..) |
| How to Apply | Confirm in your quote. | THREE directs small-business prospects to an online quote and says licensed Small Business Advisors can help with the process. [7](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: This is the route for the overall THREE product. It does not show whether Directors and Officers will be offered for a particular business or whether a customer can bind that line without an issued policy..) |
