Commercial Umbrella vs Commercial Excess Liability Policy

Commercial Umbrella vs Commercial Excess Liability Policy

Your insurance agent has just given two quotes to review.  One is for a Commercial Umbrella and one is for an Excess Liability policy.  What is the difference?

A Commercial Umbrella policy and a Commercial Excess policy both provide additional liability limits above underlying policies, but they work differently. The main differences are scope of coverage and flexibility.


1. Commercial Excess Policy

A Commercial Excess policy simply adds extra limits over a specific underlying policy and follows the same terms and conditions.

Key characteristics:

  • Provides additional limits only
  • Follows the underlying policy wording
  • Covers only what the underlying policy covers
  • Does not broaden coverage

Example:

  • Your Commercial Auto Liability policy limit = $1,000,000
  • You purchase a $4,000,000 Excess policy

If a claim is $3,000,000:

  • Auto policy pays $1,000,000
  • Excess policy pays $2,000,000

If the underlying policy doesn’t cover the claim, the excess policy won’t either.


2. Commercial Umbrella Policy

A Commercial Umbrella policy also adds extra limits, but it can also broaden coverage beyond the underlying policies.

Key characteristics:

  • Provides additional limits
  • May cover multiple underlying policies (GL, Auto, Employers Liability)
  • Can drop down to cover certain claims not covered by the underlying policy
  • Has its own coverage language

Example: A claim might not be covered under your General Liability policy due to a restriction, but the Umbrella might cover it (sometimes subject to a self-insured retention, like a deductible).


Simple Comparison

Broadens coverage No Sometimes

 Simple way to remember:

  • Excess = more limit only
  • Umbrella = more limit + sometimes broader coverage
