[3](https://www.aig.com/home/risk-solutions/business/casualty/excess-casualty "Excess Casualty Insurance") [6](https://www.markel.com/us/commercial/small-business/small-business-casualty-and-property "Small Business Casualty and Property 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)

## Markel Insurance: Specialty Business and Products

Markel Insurance is Markel Group's specialty and small-business insurance business, with offerings across packages, workers' compensation, cyber, professional and management liability, property, marine, and surety.

## What Is Umbrella and Excess Liability Insurance?

Umbrella or excess insurance adds liability limits above the policies named in the quote after a covered claim exhausts their limits. It may fit if a contract sets higher limits; check which primary policies are listed and any gaps between them. [7](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance "Liability Insurance") [8](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [9](https://www.insurance.ca.gov/0200-industry/0050-renew-license/0200-requirements/casualty/lines-of-ins.cfm "Lines of Insurance") [10](https://www.coverdash.com/coverage "Coverage Hub") [11](https://kinro.com/products "Products")

## Key Differences in Umbrella and Excess Liability Insurance

### Placement scope and stated audience

AIG markets admitted and non-admitted capacity for lead umbrella, mid-excess, and high-excess placements. Markel’s overview describes umbrella excess for small-business risks, subject to underlying coverage and risk review. The AIG page names tower positions; Markel’s page frames a small-business audience. Ask Markel whether your class and state fit its appetite. [3](https://www.aig.com/home/risk-solutions/business/casualty/excess-casualty "Excess Casualty Insurance") [6](https://www.markel.com/us/commercial/small-business/small-business-casualty-and-property "Small Business Casualty and Property Insurance")

### Policy detail and application

AIG says underlying policies, attachment points, and follow-form terms depend on the account. Markel invites customers or brokers to contact its team, while the overview does not establish bind timing or the terms of an issued policy. Ask for the policy form, limits, exclusions, and conditions before comparing the proposals. [3](https://www.aig.com/home/risk-solutions/business/casualty/excess-casualty "Excess Casualty Insurance") [6](https://www.markel.com/us/commercial/small-business/small-business-casualty-and-property "Small Business Casualty and Property Insurance")

## What to Confirm in Umbrella and Excess Liability Insurance Quotes

- Ask Markel which small-business classes and states it will consider and request the underlying-policy and attachment schedule; ask AIG for the insurer and form proposed for your tower. [3](https://www.aig.com/home/risk-solutions/business/casualty/excess-casualty "Excess Casualty Insurance") [6](https://www.markel.com/us/commercial/small-business/small-business-casualty-and-property "Small Business Casualty and Property Insurance")
