[8](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance "Liability Insurance") [9](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [10](https://www.insurance.ca.gov/0200-industry/0050-renew-license/0200-requirements/casualty/lines-of-ins.cfm "Lines of Insurance") [11](https://www.coverdash.com/coverage "Coverage Hub") [12](https://kinro.com/products "Products")

## What Are the Key Differences Between AIG and CNA Umbrella and Excess Liability Insurance?

### Form and underlying coverage

CNA says its umbrella forms are designed to align with most underlying terms and conditions and lists several built-in enhancements, including crisis management, waiver of subrogation, and most-favorable venue.

### Capacity and buyer support
