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

A Named Carrier for a Narrow Audience Versus No Carrier for a Broad One

USI's own page states that the AICPA Professional Liability Program, which it runs as the endorsed producer through its USI Affinity division, is "underwritten by CNA," naming the carrier for that specific program. [8] Corgi's Miscellaneous E&O listing names no carrier at all; its general disclosures describe affiliated or third-party partner carriers without identifying which applies to this line. [2]

CPA Firms Only Versus a Catch-All for Service Businesses

USI markets the AICPA program to sole practitioners and regional CPA firms specifically, and has been the endorsed AICPA Program provider since 1994. [8] Corgi markets Miscellaneous E&O to service-based businesses generally, positioned as what's left over once a business doesn't fit Corgi's own Tech E&O, Real Estate E&O or Lawyer E&O products. [3]

A Named Risk-Management Service Versus None Described

USI says firms enrolled in the AICPA program get supportive claims handling and exclusive access to risk-management resources, including engagement-letter templates, in addition to the coverage itself. [8] Corgi's Miscellaneous E&O listing describes no comparable risk-management resources or claims-handling service. [3]

What Should You Confirm in Corgi and USI Insurance Services Professional Liability (E&O) Insurance Quotes?

  • If you're a CPA firm, ask USI whether your quote falls under the AICPA program or its general Business Services brokerage, since USI runs both. [9]
  • Ask Corgi to name the underwriting carrier for your Miscellaneous E&O quote; the reviewed pages don't identify one. [2]
  • Get published limit or premium figures from both; neither reviewed page shows them for these lines. [8] [3]
  • Ask USI which risk-management resources actually apply to your firm size before assuming the full engagement-letter library is included. [8]

Areas of coverage
