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

How Clearly the Line Is Described

AIG describes its professional E&O as responding to allegations of negligence in services rendered to others, including third-party economic loss. Berkshire Hathaway Specialty Insurance’s current U.S. transactional-liability page lists E&O as a product, but its reviewed record does not specify a professional-services trigger. Buyers can use AIG’s description to frame questions about negligence allegations; BHSI’s quote and form must establish the actual scope. [1] [4]

Buyer Profile and Capacity

AIG identifies public and private service providers as its audience without promising every applicant qualifies. BHSI lists transactional-liability sectors including manufacturing, finance, technology, real estate, energy, healthcare and retail. That list concerns the broader transactional-liability practice, so it does not by itself establish E&O eligibility. A business should confirm whether its requested E&O relates to ongoing services or a transaction placement. [1] [4]

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

Ask AIG for the covered-services definition, exclusions and policy-specific issuer. [1]
Ask BHSI to identify the E&O product, intended insured and applicable trigger rather than relying on the broader transactional-liability sector list. [4]
