## Summary

Counterpart documents private-company management-liability features; Aon explains Side A/B/C structure and insurer selection. [3](https://www.aon.com/en/capabilities/risk-transfer/directors-and-officers-liability-insurance "Directors’ and Officers’ (D&O) Liability Insurance") [6](https://yourcounterpart.com/products/do "Private Directors & Officers Liability Insurance")

## What Is Aon?

Aon’s U.S. Commercial Risk terms describe brokerage for certain insurance programs, while its Middle Market page describes a dedicated practice for mid-sized organizations across North America.

## 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. [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")

## Key Differences in D&O Insurance

### Private-Company Product and Broker Program

Counterpart describes a management-liability product for private companies and lists claim scenarios its D&O coverage addresses. Aon explains the Side A, B and C structure but does not publish a specific policy grant. Compare Counterpart’s named scenarios with the carrier form Aon proposes, including company reimbursement and entity coverage.

### Claim Scenarios and Eligibility

Counterpart targets private companies and also describes nonprofit coverage. Aon discusses public and private firms without a detailed underwriting schedule. Ask Counterpart how its eligibility applies to your entity type and ask Aon which insurers will consider the same ownership and governance structure. [3](https://www.aon.com/en/capabilities/risk-transfer/directors-and-officers-liability-insurance "Directors’ and Officers’ (D&O) Liability Insurance") [6](https://yourcounterpart.com/products/do "Private Directors & Officers Liability Insurance")

## What to Confirm in D&O Insurance Quotes

## Offering Details

| Criteria | Aon Directors and Officers Liability brokerage and risk-advisory offering | Private Company and Nonprofit Directors & Officers Liability |
| --- | --- | --- |
| Role in This Line | Aon markets D&O broking and advisory services, including insurer selection and program design. It does not issue the described coverage or name the carrier for a buyer’s placement. [3](https://www.aon.com/en/capabilities/risk-transfer/directors-and-officers-liability-insurance "Directors’ and Officers’ (D&O) Liability Insurance") (Evidence: Company-reported; scope: Aon’s official global product/capability page.

(Evidence: Company-reported; scope: The cited pages do not map a particular insurer to a D&O quote or state..) |
| Issuing Insurer | The reviewed page does not identify the insurer or the legal producing entity for a specific placement. Ask Aon to identify both for the quoted risk.

| Coverage Features | Aon explains D&O policies generally through Side A individual protection when company indemnity is unavailable, Side B reimbursement when the company indemnifies a director or officer, and Side C entity coverage, with different descriptions for public and private companies. It notes exclusions can apply; an issued policy determines the actual scope. [3](https://www.aon.com/en/capabilities/risk-transfer/directors-and-officers-liability-insurance "Directors’ and Officers’ (D&O) Liability Insurance") (Evidence: Company-reported; scope: Aon’s broker-authored explanation of the insurance line.

Those are broker services, not an insurer claim decision or guarantee.
