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

CPA Firms Sit on Different Sides of Each Provider

USI's core professional-liability offering, the AICPA Professional Liability Program, is built specifically for CPA firms and sole practitioners. ⁴ Beazley's MediaTech form applies a Professional Services definition that narrows which professions its trigger reaches:

The sample form's definition of Professional Services excludes services performed as an accountant, architect, surveyor, health care provider, lawyer, insurance or real estate agent or broker, or civil or structural engineer, so those licensed professions are not covered by this professional E&O trigger. ³Company-reported. Sample policy form F00731, 022019 edition, Professional Services definition; a business in one of these excluded professions would need different coverage even if it buys MediaTech.

A CPA firm would find a program purpose-built for it at USI and a narrower Beazley definition covering the same profession.

What Comes With the Policy

USI says AICPA program enrollees get supportive claims handling and exclusive risk-management resources, including engagement-letter templates. ⁴ Beazley says its cyber and tech claims team has handled thousands of E&O claims, describing coverage of implementation errors alongside software failures and IP disputes. ¹
