[3](https://www.aon.com/en/capabilities/risk-transfer/directors-and-officers-liability-insurance "Directors’ and Officers’ (D&O) Liability Insurance") [6](https://www.zurichna.com/insurance/management-liability "Management Liability Insurance | Zurich U.S.")

## 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. The public materials reviewed do not identify the licensed producer or insurer for a particular placement. Ask which entity will produce each line and which insurer will issue the policy; request jurisdiction details for the proposed placement and ask how compensation and claim notice work for your account.

## Zurich U.S. Business Insurance: Products, Access, and Claims

Zurich U.S. serves Middle Market businesses and large or national accounts with commercial property-casualty and specialty insurance. Buyers can explore product lines and work through an agent or broker; the insurer named on a quote or policy identifies which Zurich company underwrites that coverage.

## 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. [7](https://www.thehartford.com/business-insurance/glossary-of-business-insurance-terms "Glossary of Business Insurance Terms") [8](https://eperils.com/wp-content/uploads/2016/09/14-02-18480.pdf "The Chubb Primary Directors & Officers and Entity Securities Liability Insurance") [9](https://asset.trvstatic.com/download/assets/pdo-3001.pdf/d66bd58e63c911ee99d14294a32ecb95 "Private Company Directors and Officers Liability Coverage")

## Key Differences in D&O Insurance

Zurich says D&O can protect directors’ personal assets and address covered company legal costs, and that its claims team members are attorneys. Aon explains Side A, B and C and says broker and claims teams collaborate in negotiations. Zurich’s team handles insurer claims work; Aon supports placement and advocacy. [3](https://www.aon.com/en/capabilities/risk-transfer/directors-and-officers-liability-insurance "Directors’ and Officers’ (D&O) Liability Insurance") [6](https://www.zurichna.com/insurance/management-liability "Management Liability Insurance | Zurich U.S.")

### Company Types and Market Analysis

Zurich lists options for public, private and nonprofit organizations, including IPOs. Aon describes services for public and private companies and uses insurer-selection analytics. A nonprofit should confirm the exact Zurich form; Aon buyers can ask how analytics guide limits and carrier selection.

## Offering Details

| Criteria | Aon Directors and Officers Liability brokerage and risk-advisory offering | Zurich Directors and Officers Liability Insurance |

| 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.
