What Are the Key Differences Between Alliance Risk and USI Insurance Services Professional Liability (E&O) Insurance?

A CPA-Specific Program

USI describes its AICPA Professional Liability Program for CPA firms and names the insurer behind it:

USI's own page states that the AICPA Professional Liability Program is "underwritten by CNA," naming the carrier for that specific program. USI's general Business Services E&O placements do not name an insurer. ²Company-reported. Direct quote from the AICPA program page; CNA underwrites only this named program, not USI's other professional-liability placements.

Alliance Risk also lists accountants among its target professions but does not name a CPA-only program. If you are a CPA, ask whether your firm qualifies for USI’s AICPA program or a general E&O placement. ¹
