## What Are the Key Differences Between Berkshire Hathaway Specialty Insurance and USI Insurance Services Professional Liability (E&O) Insurance?

### Professional class and program audience

Berkshire Hathaway Specialty Insurance names staffing, management consulting, marketing and real-estate firms for Miscellaneous Professional Liability and separately lists law-firm size bands. USI’s AICPA Professional Liability Program specifically targets sole practitioners and regional CPA firms; USI brokers the program rather than underwriting it. A CPA evaluating these options should distinguish that endorsed CPA placement from BHSI’s named lawyers or miscellaneous professional products, then verify whether BHSI has a form for the firm’s services. [6](https://www.bhspecialty.com/wp-content/uploads/marketing/Professional-First-Professional-Liability-Overview-US.pdf "Professional First Professional Liability Overview") [11](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity")

### Service tied to the CPA placement

USI says AICPA program members receive claims support and risk-management resources such as engagement-letter templates. BHSI describes a Professional First claims group integrated with underwriting. These are service descriptions, not evidence of different claims outcomes. Ask both providers how notice is given and what support you receive after a client allegation. [11](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity") [6](https://www.bhspecialty.com/wp-content/uploads/marketing/Professional-First-Professional-Liability-Overview-US.pdf "Professional First Professional Liability Overview")

## What Should You Confirm in Berkshire Hathaway Specialty Insurance and USI Insurance Services Professional Liability (E&O) Insurance Quotes?

- Ask USI whether your firm qualifies for the AICPA program and confirm its named insurer, CNA, on the quote. [11](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity")
- Ask BHSI for the policy form, limit and eligibility criteria for your CPA services. [6](https://www.bhspecialty.com/wp-content/uploads/marketing/Professional-First-Professional-Liability-Overview-US.pdf "Professional First Professional Liability Overview")
- Compare claims reporting instructions and risk resources in writing. [11](https://www.usi.com/programs/affinity-programs/accountants-professional-liability/ "Accountants Professional Liability — USI Affinity")
