What Is Umbrella and Excess Liability Insurance?

Umbrella and excess liability insurance can add limits above the underlying policies it lists, subject to its coverage terms.

What Does Umbrella and Excess Liability Insurance Cover?

Commercial umbrella insurance can provide additional liability limits above scheduled underlying policies for covered claims. 1,2

Additional Limits for Covered Claims

Ask what the quote calls umbrella or excess coverage, and compare its underlying policies, attachment terms and any additional coverage. 1,3,4

Who Needs Umbrella and Excess Liability Insurance?

Consider extra liability limits when a large claim could exceed your primary coverage or a contract requires higher limits. 1,5

Coverage Examples

These are examples, not coverage guarantees. Your policy terms and the facts of the claim determine what is covered.

What happened

A Claim Reaches Your Primary Limit

A covered liability claim uses up the limit of your primary policy.

How coverage may help

An umbrella or excess layer may provide additional limits if that policy is scheduled underneath it and the claim meets the attachment terms. 1,2,5

What happened

Your Primary Policy Excludes a Claim

A claim is excluded by your primary policy, and you turn to the umbrella.

How coverage may help

The umbrella may not fill the gap. Any broader protection depends on its own coverage terms, exclusions and self-insured retention. 1,2,3

How Do You Compare Coverage and Costs?

Underlying Policies, Attachment and Gaps

Confirm which policies are listed as underlying insurance and at what limits. 1,2,5

The extra layer begins paying according to its attachment terms. It may respond after a single occurrence uses up the primary limit, after the primary aggregate is exhausted, or on another stated basis. Confirm the terms for each underlying policy, including auto if you need it covered. 1,2 6 1,2,5

Ask whether the quote can respond when an underlying policy does not, and what self-insured retention would apply in that case. 2,3
Comparison pointWhat to locate in the quote
Underlying scheduleWhich policies and limits are listed underneath
AttachmentOccurrence, aggregate, or another stated basis
Response without underlyingWhether the extra layer can respond, and at what retention
Additional coverageAny protection the extra layer adds that the underlying policies do not

Auto, Specialty Exclusions and Contract Limits

For auto claims, ask whether the commercial-auto or trucking liability policy is listed as underlying insurance. 6 Ask whether employment-practices, professional-liability, product-recall and similar specialty exposures are included or excluded. 1 Compare the extra limits with any contract-required liability limits and with the underlying limits those contracts assume. 5,2

How Does It Compare With Related Coverage?

An umbrella discussion does not replace checking the underlying general-liability, auto or employers-liability terms. 1,6

What Do You Need for a Quote?

Prepare the schedule of current liability policies, their limits, and any contract-required higher limits. 1,5

Liability Schedule and Required Limits

Item to bringHow it is used
Current liability policies and limitsTo build the underlying schedule
Named insureds on each policyTo see whether the extra layer names the same parties
Contracts that require higher limitsTo compare the extra limit with the obligation
Auto or trucking liability termsTo ask whether those policies sit underneath

Key Terms in Plain English

Underlying Policy

A policy scheduled beneath the additional liability layer, at a stated limit. 1,2,5

Attachment

The point at which the additional limits begin to respond; check occurrence and aggregate exhaustion terms. 1,2

Frequently Asked Questions

Does an Umbrella Automatically Cover Every Primary Policy?

No. The underlying schedule identifies the policies and limits beneath it. Check that each policy you want covered is listed. 1,2,5

Does It Always Fill a Gap in Primary Coverage?

No. Any broader protection depends on the umbrella's terms and exclusions, and a self-insured retention may apply. 2,3

When Do Commercial Umbrella Limits Start Paying?

Check the attachment terms: the additional limits may apply after a covered occurrence exhausts an underlying limit, after an aggregate is exhausted, or on another stated basis. The quote should identify the required underlying limits. 1,2 1,2,5

Can a Commercial Umbrella Sit Above Trucking or Auto Liability?

It can, but check that the commercial-auto or trucking liability policy is listed as underlying insurance. Review the umbrella and primary policy terms together to establish how the additional limits apply. 6 1,6
