[1](https://www.markel.com/about-us "About us") [2](https://www.sec.gov/Archives/edgar/data/1096343/000109634326000020/mkl-20251231.htm "Markel Group Inc. 2025 Form 10-K")

## 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.

## 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. [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")

## Key Differences in Umbrella and Excess Liability Insurance

### Underlying Coverage

Nationwide describes an added layer above underlying policies such as general liability or business auto, with terms tied to the business and its coverage. Markel describes additional limits beyond primary policies but leaves the schedule to underwriting review. Ask both whether the same underlying policies and limits qualify. [3](https://www.markel.com/us/commercial/small-business/small-business-casualty-and-property "Small Business Casualty and Property Insurance") [7](https://www.nationwide.com/business/insurance/umbrella-policy/ "Commercial Umbrella Liability Insurance from Nationwide")

### Quote Information

Nationwide says it requests business, policy, loss, and payroll information for a quote. Markel’s overview invites contact with the company or underwriting team without listing the submission details. Buyers can prepare the same exposure and loss information for each submission, then compare what else is required. [3](https://www.markel.com/us/commercial/small-business/small-business-casualty-and-property "Small Business Casualty and Property Insurance") [7](https://www.nationwide.com/business/insurance/umbrella-policy/ "Commercial Umbrella Liability Insurance from Nationwide")

### Agent and Underwriting Route

Nationwide directs prospective customers to an agent or quote request, while Markel invites customers or brokers to contact its underwriting team. Neither public overview establishes a binding timeline or standard limit, so confirm who handles the submission and when the quote can be issued. [3](https://www.markel.com/us/commercial/small-business/small-business-casualty-and-property "Small Business Casualty and Property Insurance") [7](https://www.nationwide.com/business/insurance/umbrella-policy/ "Commercial Umbrella Liability Insurance from Nationwide")

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

- Ask Nationwide which underlying liability policies and limits it requires and what loss or payroll records to submit. [7](https://www.nationwide.com/business/insurance/umbrella-policy/ "Commercial Umbrella Liability Insurance from Nationwide")
- Ask Markel whether the same underlying schedule fits its appetite, and request its issuer, attachment point, limit, and retention. [3](https://www.markel.com/us/commercial/small-business/small-business-casualty-and-property "Small Business Casualty and Property Insurance")
