Alliance Risk vs USI Insurance Services Professional Liability (E&O) Insurance

Alliance Risk places professional liability (errors and omissions, or E&O) coverage as a broker, saying it backs placements with risk-specific underwriting input and carrier partnerships rather than underwriting the policy itself. ³Company-reported. Professional liability product page.

For CPA firms, USI runs the AICPA Professional Liability Program through its USI Affinity division as the endorsed producer, rather than underwriting the policy itself. USI's general Business Services practice separately brokers errors and omissions/professional liability coverage for other business types. ^7,9Company-reported. AICPA program page and Business Services practice page.

The reviewed professional liability page does not name the insurer that would issue a policy; it refers generally to 'strong carrier partnerships' without identifying a specific carrier. ³Not publicly disclosed. Professional liability product page as read on 2026-09-23.

USI's own page states that the AICPA Professional Liability Program is "underwritten by CNA," naming the carrier for that specific program.

USI describes the policy as insuring a CPA and their practice against third-party claims that professional services caused financial harm, providing a defense and paying damages for covered claims arising from high-risk situations tied to new clients, changing business plans, or new laws and regulations. ⁷Company-reported.
