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 Fiduciary Liability Insurance?
Fiduciary liability can protect your company and plan fiduciaries when participants claim mishandling of an employee benefit plan. If you sponsor a retirement or health plan, check who is insured and whether both administration errors and fiduciary-breach claims are addressed. 8,9,10
Key Differences in Fiduciary Liability Insurance
Placement and Plan Fit
CNA says its fiduciary offering is written for public, private, and nonprofit organizations. Aon’s Professional Services Practice names law, accounting, and consulting firms as its audience for fiduciary placement and advice. Those market descriptions differ in emphasis but do not determine eligibility for a particular plan sponsor. Buyers should provide plan type, size, and organization class to both before relying on a product overview. 3 7
Coverage Terms and Service
CNA lists defense and claim expenses, certain legal penalties, voluntary-compliance costs, and pre-claim investigation costs, and says insureds can access a claims team and expert guidance. Aon describes data-informed risk and human-capital advice but does not specify fiduciary claim costs or claims services. Ask CNA how those categories apply to the proposed policy and ask Aon what claim advocacy its broker engagement includes. 3 7
