## 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. [11](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance "Liability Insurance") [12](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [13](https://www.insurance.ca.gov/0200-industry/0050-renew-license/0200-requirements/casualty/lines-of-ins.cfm "Lines of Insurance") [14](https://www.coverdash.com/coverage "Coverage Hub") [15](https://kinro.com/products "Products")

## What Are the Key Differences Between Gallagher and Nationwide Umbrella and Excess Liability Insurance?

### Underlying Coverage and Form

Gallagher places umbrella and excess through an outside-carrier casualty practice and offers customized program design, including alternative risk programs. Nationwide describes an added layer above underlying general liability or auto policies and routes prospects to an agent. If you need a coordinated casualty structure, ask Gallagher which alternatives are available and ask Nationwide for the proposed layer over your current policies. [6](https://www.ajg.com/insurance/casualty-insurance/ "Casualty Insurance") [10](https://www.nationwide.com/business/insurance/umbrella-policy/ "Commercial Umbrella Liability Insurance from Nationwide")

### Limits, Eligibility, and Buying

Gallagher describes pre-renewal meetings with finance, HR, operations and risk teams, plus gap analysis and contract/form review. Nationwide requests policy and loss information for a quote but does not describe those review services. Ask Gallagher which contracts and forms it will analyze; ask the Nationwide agent whether the placement includes review of gaps between the excess and underlying wording. [6](https://www.ajg.com/insurance/casualty-insurance/ "Casualty Insurance") [10](https://www.nationwide.com/business/insurance/umbrella-policy/ "Commercial Umbrella Liability Insurance from Nationwide")

### Support to Confirm

Gallagher says a claims and loss-control advocacy group reviews legacy loss information to build mitigation programs. Nationwide’s public umbrella overview does not describe excess-claims advocacy. Ask Gallagher who will advocate if a large liability claim reaches the excess layer and ask Nationwide who handles claim escalation between the primary carrier and umbrella insurer. [6](https://www.ajg.com/insurance/casualty-insurance/ "Casualty Insurance") [10](https://www.nationwide.com/business/insurance/umbrella-policy/ "Commercial Umbrella Liability Insurance from Nationwide")

## What Should You Confirm in Gallagher and Nationwide Umbrella and Excess Liability Insurance Quotes?

- Ask Gallagher and Nationwide to identify the actual issuing insurer, required scheduled underlying policies and limits, attachment point, and exclusions in the quote.
