[3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/professional-liability "Professional Liability Insurance") [9](https://www.bhspecialty.com/wp-content/uploads/marketing/Professional-First-Professional-Liability-Overview-US.pdf "Professional First Professional Liability Overview") [8](https://www.bhspecialty.com/us-products/us-executive-and-professional-lines/professional-liability/ "Professional First Professional Liability")

## What Is AIG?

AIG is the marketing name for American International Group, Inc.; AIG says its insurance products are written or provided by subsidiaries or affiliates. Its U.S. business pages list commercial casualty, property, cyber, management and professional liability, and specialty programs, but a brand-level page does not identify the insurer for a particular policy.

## What Is Professional Errors and Omissions (E&O) Insurance?

Professional liability can help pay defense costs and covered losses when a client says your advice or service caused financial harm. If customers rely on your work, list every service you provide and check the claims-made reporting and prior-work terms. [11](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [12](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [13](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [14](https://www.hiscox.com/documents/pl-sample-policy-wording.pdf "Professional Liability – US Direct Errors and Omissions Insurance")

## Key Differences in 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. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/professional-liability "Professional Liability Insurance") [9](https://www.bhspecialty.com/wp-content/uploads/marketing/Professional-First-Professional-Liability-Overview-US.pdf "Professional First Professional Liability Overview")

### 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. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/professional-liability "Professional Liability Insurance") [9](https://www.bhspecialty.com/wp-content/uploads/marketing/Professional-First-Professional-Liability-Overview-US.pdf "Professional First Professional Liability Overview")

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

- Ask AIG for the covered-services definition, exclusions and policy-specific issuer. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/professional-liability "Professional Liability Insurance")
- Ask BHSI to identify the E&O product, intended insured and applicable trigger rather than relying on the broader transactional-liability sector list. [9](https://www.bhspecialty.com/wp-content/uploads/marketing/Professional-First-Professional-Liability-Overview-US.pdf "Professional First Professional Liability Overview")

[3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/professional-liability "Professional Liability Insurance") (Evidence: Company-reported; scope: General professional-liability claims services described by AIG. The page does not state account-specific service standards or identify the administrator for a particular policy..) | The Professional First overview describes its in-house claims handling group as experienced in complex, high-value claims and integrated with underwriting. [9](https://www.bhspecialty.com/wp-content/uploads/marketing/Professional-First-Professional-Liability-Overview-US.pdf "Professional First Professional Liability Overview") (Evidence: Company-reported; scope: Company-reported portfolio-level claim-service description, not independently measured claims performance..) |

Customer ratings for AIG are low: Trustpilot shows 1.9 out of 5 from 252 reviews, and NerdWallet gives 2.5 stars and notes more claims complaints than expected. These pages cover many AIG products and countries, so they only loosely describe business insurance.

- NerdWallet: NerdWallet editorial rating 2.5 (stars).
