Key Differences in Umbrella and Excess Liability Insurance

Which Primary Policies Are Extended

biBerk says its umbrella only applies to coverages included in the underlying policy and gives auto as an example that requires commercial auto below. Nationwide describes an added layer above underlying coverage such as general liability or business auto, with the terms depending on the business and its existing insurance. Ask both providers to name the scheduled policies in your quote so a desired exposure is not assumed to be part of the layer. 3 7

Quote Channel and Account Information

Nationwide directs buyers to contact an agent or request a quote and asks for business, policy, loss, and payroll information. biBerk offers online or phone quote access, with an existing liability policy required. Gather those records before requesting terms, especially if you need the umbrella to align with multiple underlying limits. 7 3

Neither reviewed overview sets a universal limit or retention; biBerk additionally lists examples of exclusions such as war and contractual liability. 7 3

What to Confirm in Umbrella and Excess Liability Insurance Quotes

  • Ask Nationwide for its offered limit, retention, and policy form for your scheduled coverage. 7
  • Ask biBerk how its listed exclusions affect your business contracts. 3
