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.

Liberty Mutual lists umbrella/excess for wholesale businesses but gives no limit or attachment figure in the reviewed claim. Use its figures as context and request a quote for your underlying limits. [4](https://joinalliancerisk.com/umbrella-excess-liability-insurance/ "Umbrella & Excess Liability Insurance") [7](https://business.libertymutual.com/industries/wholesale/ "Wholesale Distribution") ### The products describe different relationships to underlying policies Alliance Risk says umbrella coverage may broaden some underlying terms, while excess coverage follows the underlying policy and only raises its limit; both retain underlying exclusions. Liberty Mutual's wholesale page names umbrella/excess as an option but does not describe attachment terms. Ask for a schedule showing each underlying policy, attachment point, and any broader wording before comparing the layer. [4](https://joinalliancerisk.com/umbrella-excess-liability-insurance/ "Umbrella & Excess Liability Insurance") [7](https://business.libertymutual.com/industries/wholesale/ "Wholesale Distribution") ## What to Confirm in Umbrella and Excess Liability Insurance Quotes - Ask Alliance Risk whether the quote is umbrella or follow-form excess, its attachment point, exclusions, and price at each limit. [4](https://joinalliancerisk.com/umbrella-excess-liability-insurance/ "Umbrella & Excess Liability Insurance") - Ask Liberty Mutual's broker for available limits and which wholesale underlying policies the layer follows.
