## What Is Chubb?

Chubb is the marketing name for a global insurance group whose U.S. companies underwrite commercial property, casualty, cyber and financial-lines coverage, including technology-focused DigiTech ERM and small-business packages. Founders and finance teams typically work through an appointed agent, then receive a policy issued by a named Chubb-group insurer rather than by the Swiss holding company.

## What Is Umbrella and Excess Liability Insurance?

Commercial umbrella insurance can provide additional liability limits above scheduled underlying policies for covered claims. Don't assume umbrella and excess liability are the same coverage — the labels aren't proven synonyms. [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")

## Key Differences in Umbrella and Excess Liability Insurance

### Direct Writer Versus a Broker-Marketed Line

Chubb underwrites umbrella and excess liability. Relm Insurance markets Excess Liability Insurance as a casualty line brokers can place for clients whose underlying limits may not be enough, and it does not name an issuing insurer on the reviewed page. Energy appears in both descriptions, but the roles differ. [4](https://www.chubb.com/us-en/business-insurance/umbrella-excess-casualty.html "Umbrella & Excess Casualty Insurance") [8](https://relminsurance.com/lines-of-business/casualty-insurance/ "Casualty Insurance")

### Segment Options Versus Exposure Types

Chubb structures separate options for large global and national companies, mid-sized companies, energy and construction. Relm Insurance highlights companies with large vehicle fleets, significant public interaction or large contracts, and high-risk industries such as energy, manufacturing or transportation. Relm Insurance says brokers always advise on the exact excess limits needed. [4](https://www.chubb.com/us-en/business-insurance/umbrella-excess-casualty.html "Umbrella & Excess Casualty Insurance") [8](https://relminsurance.com/lines-of-business/casualty-insurance/ "Casualty Insurance")

### How a Buyer Reaches Paper

Appointed brokers use Chubb Express Umbrella to quote and bind, and buyers can request a quote online or through an appointed agent. Relm Insurance’s reviewed page does not describe a buyer-facing application; it addresses brokers placing the line. Neither page publishes numeric excess limits.

- Ask the Relm Insurance broker which underlying liability policies attach. [8](https://relminsurance.com/lines-of-business/casualty-insurance/ "Casualty Insurance")
