Key Takeaways

  • UMBRELLA policies provide EXCESS coverage above underlying policies AND may provide DROP-DOWN coverage for claims not covered by underlying policies
  • EXCESS policies provide ONLY excess limits above underlying policies—they follow the same terms and conditions as the underlying policy
  • Underlying insurance requirements: Umbrella policies require minimum limits on underlying policies (CGL, auto, employers liability)
  • SELF-INSURED RETENTION (SIR) is the deductible on umbrella policies for claims where the umbrella drops down to cover
  • Umbrella policies typically provide $1-25 million in additional limits at relatively low cost compared to increasing primary limits

Commercial Umbrella and Excess Liability

Umbrella vs. Excess Liability

Both provide additional liability limits, but there are important differences:

FeatureUmbrellaExcess
Coverage ScopeMay be BROADER than underlyingFOLLOWS underlying exactly
Drop-DownYES—covers some claims underlying doesn'tNO—only pays above underlying
Own TermsHas its own policy languageFollows form of underlying
SIRApplies when dropping downUsually no SIR
CostTypically higherTypically lower

Quick Answer: An umbrella provides excess limits PLUS drop-down coverage for claims not covered by underlying policies. An excess policy only provides additional limits above the underlying—it follows the underlying policy's terms exactly.


How Umbrella Coverage Works

1. Excess Over Underlying Limits

When the underlying policy limit is exhausted, the umbrella pays above it.

Example:

  • CGL limit: $1,000,000
  • Umbrella: $5,000,000
  • Claim: $3,500,000
  • CGL pays $1,000,000 → Umbrella pays $2,500,000

2. Drop-Down Coverage

When the underlying policy excludes a covered claim, the umbrella "drops down."

Example:

  • CGL excludes personal injury (libel)
  • Umbrella covers personal injury
  • Claim for defamation: $500,000
  • Umbrella pays $500,000 (minus SIR)

3. Self-Insured Retention (SIR)

Definition: The deductible that applies when the umbrella drops down (no underlying coverage).

Typical SIR: $10,000 - $25,000

How It Works:

  • Claim covered by umbrella but not underlying
  • Insured pays SIR first
  • Umbrella pays remainder up to limit

Underlying Insurance Requirements

Umbrella policies require minimum limits on underlying policies:

Underlying PolicyTypical Minimum Required
CGL$1,000,000 per occurrence / $2,000,000 aggregate
Business Auto$1,000,000 CSL
Employers Liability$500,000 / $500,000 / $500,000

Gap Coverage: If underlying limits are less than required, the umbrella may not respond—or may only pay excess of required amount.


When to Use Umbrella vs. Excess

Use Umbrella When:

  • Broader coverage needed beyond underlying
  • Want drop-down protection for excluded claims
  • Underlying policies have gaps
  • Need catastrophic protection

Use Excess When:

  • Only need higher limits (same coverage)
  • Want to follow underlying terms exactly
  • Lower premium is priority
  • Underlying coverage is comprehensive

Typical Umbrella Limits

LimitAnnual Premium (Typical)
$1 million$500 - $1,500
$5 million$1,500 - $4,000
$10 million$3,000 - $8,000
$25 million$8,000 - $20,000

Note: Umbrella premiums are relatively low because claims are rare (underlying pays first).
