## 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. [1](https://www.aig.com/investor-relations "Investor Relations") [2](https://www.aig.com/home/risk-solutions/business "Business")

[AIG profile](https://spot.insure/insurance-providers/aig)

## 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. [7](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [8](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [9](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [10](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

### What Each Record Says Is Covered

AIG describes professional E&O for claims alleging negligence in services rendered to others, including third-party economic loss. Liberty Mutual’s record identifies its professional-errors-and-omissions product and summarizes the policy’s coverage scope. Buyers should compare the actual definitions and exclusions, especially for contract allegations and economic loss, rather than treating the product titles as equivalent. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/professional-liability "Professional Liability Insurance") [6](https://business.libertymutual.com/commercial-solutions/programs/ "Programs")

### Customization and Quote Terms

AIG says it can tailor coverage to a company’s professional services. Liberty Mutual describes the businesses targeted by its offering. Those different levels of detail matter when an applicant’s work crosses several occupations: request confirmation that every service appears in the quote and obtain the insurer, limit and retention. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/professional-liability "Professional Liability Insurance") [6](https://business.libertymutual.com/commercial-solutions/programs/ "Programs")

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

- Ask AIG for its proposed service definition, exclusions and policy-specific limits. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/professional-liability "Professional Liability Insurance")
- Ask Liberty Mutual to verify eligibility for each service you perform and provide its quoted retention and insurer entity. [6](https://business.libertymutual.com/commercial-solutions/programs/ "Programs")
