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. 1,2

Key Differences in D&O Insurance
Private-Company Coverage and Claim Scenarios
Berkshire Hathaway Specialty Insurance describes D&O protection for investigations and derivative claims under its private-company product. Aon explains Side A, B and C structures but does not publish buyer-specific terms. Compare the BHSI claim scenarios with the carrier form Aon proposes, including who is insured and which defense costs are covered. 8 3
Program Structure and Eligibility
BHSI states eligibility characteristics for private companies, while Aon describes D&O services for public and private firms without a complete underwriting schedule. Ask BHSI how its revenue and entity criteria apply; ask Aon which markets will consider the company’s structure and governance profile. 8 3
What to Confirm in D&O Insurance Quotes
- Ask BHSI for investigation and derivative-claim wording and eligibility; ask Aon for carrier, Side A/B/C limits and exclusions. 8
