## 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. [9](https://www.iii.org/publication/insuring-your-business-small-business-owners-guide-to-insurance/specific-coverages/liability-insurance "Liability Insurance") [10](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [11](https://www.insurance.ca.gov/0200-industry/0050-renew-license/0200-requirements/casualty/lines-of-ins.cfm "Lines of Insurance") [12](https://www.coverdash.com/coverage "Coverage Hub") [13](https://kinro.com/products "Products")

## Key Differences in Umbrella and Excess Liability Insurance

### Underlying Policies and Covered Lines

biBerk says its umbrella must accompany an existing liability policy and only applies to coverages included underneath it. CFC describes one excess policy above professional liability, general liability, cyber, or a combination, and says the primary policy can come from another insurer. If your current program is split among carriers, ask CFC how it schedules each layer; biBerk’s quote needs the matching underlying coverage in place. [3](https://www.biberk.com/small-business-insurance/umbrella-insurance "Umbrella Insurance From biBerk | Get Coverage Today") [8](https://www.cfc.com/en-us/products/class/excess-umbrella/ "Excess umbrella insurance cover | CFC")

### What Happens Above the Primary Limit

Both offerings add liability capacity above primary insurance, but biBerk describes response after a covered claim exceeds an applicable policy limit, while CFC explicitly allows its layer to sit above several liability lines together. Confirm attachment points and whether the excess wording follows each underlying policy. [3](https://www.biberk.com/small-business-insurance/umbrella-insurance "Umbrella Insurance From biBerk | Get Coverage Today") [8](https://www.cfc.com/en-us/products/class/excess-umbrella/ "Excess umbrella insurance cover | CFC")

### Buying and Quote Details

biBerk offers online or phone access to quote; CFC directs interested businesses to contact it directly. CFC targets small and micro businesses across a wide range of professions, while biBerk’s reviewed claim ties eligibility to already holding underlying liability coverage. Ask what underlying limits each quote requires and which policy forms are scheduled. [3](https://www.biberk.com/small-business-insurance/umbrella-insurance "Umbrella Insurance From biBerk | Get Coverage Today") [8](https://www.cfc.com/en-us/products/class/excess-umbrella/ "Excess umbrella insurance cover | CFC")

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

- Ask CFC for its maximum excess limit and required primary limits; neither amount is published on its reviewed page. [8](https://www.cfc.com/en-us/products/class/excess-umbrella/ "Excess umbrella insurance cover | CFC")
- Give biBerk the underlying policy schedule and confirm which scheduled lines receive umbrella protection. [3](https://www.biberk.com/small-business-insurance/umbrella-insurance "Umbrella Insurance From biBerk | Get Coverage Today")
