Key Differences in Professional Liability (E&O) Insurance

A Named Insurer Versus a Rating Standard

USI names the specific underwriter behind the professional liability program it runs for CPA firms:

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. ¹¹Company-reported. Direct quote from the AICPA program page; CNA underwrites only this named program, not USI's other professional-liability placements.

Founder Shield does not name an insurer for its E&O line; it instead commits to placing policies only with carriers rated A- or better by AM Best, chosen for the client's industry. ³

Profession-Specific Program Versus Broader Client List

USI markets its named program specifically to sole practitioners and regional CPA firms, and has been the endorsed AICPA Program provider since 1994. ¹¹ Founder Shield instead names a wider range of client types for its E&O line: venture capital firms, consultants, media and advertising agencies, SaaS marketplaces, and software developers who perform services for others. ⁶

Services Bundled With Coverage

USI says CPA firms enrolled in its program get supportive claims handling and exclusive access to risk-management resources, including engagement-letter templates, in addition to the coverage itself. ¹¹ Founder Shield's E&O page does not describe a comparable risk-management service; it lists coverage for defense costs, regulatory-proceeding defense, lost earnings and employee or contractor error claims. ⁶

What to Confirm in Professional Liability (E&O) Insurance Quotes

If your business is not a CPA firm, ask USI whether its general Business Services practice, rather than the named AICPA program, would place your E&O. ¹¹
Ask Founder Shield to name its A- or better AM Best-rated carrier for your placement, since its page states a rating floor rather than a carrier. ³
Ask USI for the specific limit, retention and premium for your firm, since the AICPA program page does not publish figures. ¹¹
Neither Founder Shield's page publishes limit figures for E&O; request specific amounts directly. ⁶
