What Are the Key Differences Between Coterie Insurance and USI Insurance Services Professional Liability (E&O) Insurance?
A Named Carrier for a Narrow Program 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." 3 Coterie's MPL brochure names the policy form, "Coterie Professional Liability Errors and Omissions Insurance Declarations," but leaves the issuing insurer to the policy declarations. 1
CPA Firms Only Versus Dozens of Listed Professions
USI markets the AICPA program to sole practitioners and regional CPA firms specifically, and has been the endorsed AICPA Program provider since 1994. 3 Coterie lists dozens of eligible professions for MPL instead, including accounting services, architects and engineers, bookkeeping, human resources consulting, interior design and technology services/IT consulting. 1
A Named Risk-Management Service Versus a Published Exclusions List
USI says firms enrolled in the AICPA program get supportive claims handling and exclusive access to risk-management resources, including engagement-letter templates. 3 Coterie's MPL brochure instead publishes its base-form exclusions directly, covering bodily injury or property damage, fraud, wrongful termination and contractual liability beyond the underlying contract. 1
What Should You Confirm in Coterie Insurance 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. 5
- Ask an agent or broker to name the insurer behind your Coterie MPL declarations page, since the brochure doesn't name one. 1
- Get published limit or premium figures from USI directly, since the AICPA program page doesn't publish them. 3
- Ask an agent or broker which of Coterie's each-claim limit tiers your contract requires before binding. 1
