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
CNA Small Business Insurance: Products, Agents and Service
CNA directs small-business buyers to independent agents and describes CNA Connect as a businessowners policy for more than 600 small-business classes. Issuer and availability vary by policy and state, so confirm both in a quote. 4,5,6
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. 8,9,10
Key Differences in D&O Insurance
Claims Handling and Broker Advocacy
CNA describes how its D&O claims team handles claims and identifies covered parties. Aon says brokerage and claims teams collaborate in negotiation, a broker function rather than insurer claim authority. Ask who receives notice and how CNA’s process compares with the carrier Aon proposes. 3 7
Covered Parties and Program Structure
Aon explains Side A, B and C and differences between public and private forms. CNA publishes named covered-party and limit details. Compare insured-person definitions, entity coverage and defense-cost treatment in the proposed policy forms. 3 7
What to Confirm in D&O Insurance Quotes
- Ask CNA how claims are assigned and which parties are insured; ask Aon for its carrier, Side A/B/C terms and advocacy scope. 3
