## Summary

AIG describes entity E&O for professional negligence; Nationwide lists professional-liability products for target occupations and provides an agent-based route to coverage. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/professional-liability "Professional Liability Insurance") [7](https://www.nationwide.com/business/insurance/errors-and-omissions/ "Errors and Omissions Insurance")

## 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 Nationwide?

Nationwide’s commercial catalogue includes common small-business policies and separate specialty products. A catalogue listing does not establish eligibility or policy terms; confirm the issuing company and coverage for your state and business. [4](https://www.nationwide.com/business/insurance/small-commercial/ "Small Business Insurance") [5](https://www.nationwide.com/agents/business/ "Small Business Insurance Solutions for Agents") [6](https://www.nationwide.com/personal/about-us/terms-conditions "Terms and Conditions for Nationwide.com")

## 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. [8](https://www.tdi.texas.gov/commercial/pl-faq.html "FAQ: Professional liability insurance") [9](https://www.iii.org/article/professional-liability-insurance "Professional liability insurance") [10](https://www.sba.gov/counseling/launch-your-business/#business-insurance "Get business insurance") [11](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

### Occupations and Insuring Terms

AIG targets service providers and says its policy can be customized, while Nationwide lists occupations and businesses for its professional-liability offering. A buyer should see whether its work falls within Nationwide’s named classes and ask AIG to evaluate any unusual mix of services. Then compare the issued forms for negligence, contract allegations and defense costs. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/professional-liability "Professional Liability Insurance") [7](https://www.nationwide.com/business/insurance/errors-and-omissions/ "Errors and Omissions Insurance")

### How Coverage Is Arranged

AIG markets entity-based specialty E&O. Nationwide directs prospects through its agent channel for professional-liability coverage. An agent may help identify the right occupational product, but the quote controls the insurer, form and available limit. Ask whether your Nationwide proposal is a standalone E&O policy or coordinated with other business coverages. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/professional-liability "Professional Liability Insurance") [7](https://www.nationwide.com/business/insurance/errors-and-omissions/ "Errors and Omissions Insurance")

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

- Ask AIG to confirm eligible services and identify the policy issuer and claims-made provisions. [3](https://www.aig.com/home/risk-solutions/business/management-and-professional-liability/professional-liability "Professional Liability Insurance")
- Ask Nationwide which occupation-specific form your agent is quoting and whether its terms cover all services on your contracts. [7](https://www.nationwide.com/business/insurance/errors-and-omissions/ "Errors and Omissions Insurance")
