## 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

### Two Coverage Structures

Zurich Commercial Umbrella combines Coverage A follow-form excess liability with Coverage B lead umbrella liability. biBerk describes its layer as responding after a covered claim exceeds an applicable existing liability limit and applies only to coverage included underneath. For a buyer, Zurich’s two-part structure calls for reviewing which section responds to each exposure; biBerk’s key check is whether the relevant line is scheduled below. [6](https://www.zurichna.com/insurance/umbrella "Commercial Umbrella Insurance Coverage | Zurich Insurance") [3](https://www.biberk.com/small-business-insurance/umbrella-insurance "Umbrella Insurance From biBerk | Get Coverage Today")

### Crisis Expense and Limits

Zurich lists a Coverage C Casualty Business Crisis Expense reimbursement up to $250,000. biBerk’s reviewed offering instead names examples of exclusions, including contractual liability, intentional harm, and damage to the insured’s own property, without publishing a limit amount. Ask for the Zurich crisis-expense conditions and the biBerk limit and exclusions in the proposed forms. [6](https://www.zurichna.com/insurance/umbrella "Commercial Umbrella Insurance Coverage | Zurich Insurance") [3](https://www.biberk.com/small-business-insurance/umbrella-insurance "Umbrella Insurance From biBerk | Get Coverage Today")

Zurich also describes a claims-made excess facility of up to $100 million; that facility is distinct from the umbrella terms and should not be treated as the standard offer. [6](https://www.zurichna.com/insurance/umbrella "Commercial Umbrella Insurance Coverage | Zurich Insurance")

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

- Ask Zurich which coverage section applies and whether crisis expense reimbursement is included. [6](https://www.zurichna.com/insurance/umbrella "Commercial Umbrella Insurance Coverage | Zurich Insurance")
- Ask biBerk to show the scheduled lines, offered limit, and applicable exclusions. [3](https://www.biberk.com/small-business-insurance/umbrella-insurance "Umbrella Insurance From biBerk | Get Coverage Today")
