11.7 Commercial Umbrella and Excess Liability

Key Takeaways Explain This Topic AI

An umbrella provides excess limits above underlying policies AND can drop down to cover certain claims the underlying policies exclude, subject to a self-insured retention (SIR)

An excess policy is follow-form: it provides only additional limits above the underlying and covers nothing the underlying excludes

The self-insured retention (SIR) is the amount the insured pays when the umbrella drops down to cover a claim with no underlying coverage — distinct from a deductible

Umbrellas require the insured to maintain stated minimum underlying limits (e.g., CGL $1M/$2M, auto $1M CSL, employers liability); failure to maintain them leaves the insured paying as if the underlying were intact

Umbrella limits commonly run $1M–$25M+ at low cost because the underlying policies pay first, so umbrella claims are infrequent

Umbrella vs. Excess — The Core Distinction

Both umbrella and excess liability policies sit above primary (underlying) coverage and add limits. The difference is breadth .

• Feature Umbrella Excess (Follow-Form)
• Coverage scope May be broader than underlying Follows underlying exactly
• Drop-down Yes — covers some claims the underlying excludes No — limits only
• Own policy language Has its own terms Adopts underlying terms
• SIR Applies when it drops down Usually none
• Premium Slightly higher Slightly lower

Quick Answer: An umbrella = extra limits plus drop-down for some excluded claims (above an SIR). An excess policy = extra limits only , mirroring the underlying.

• The Three Functions of an Umbrella
• 1. Excess Over Underlying Limits

When the underlying limit is exhausted, the umbrella pays above it. Example: CGL limit $1,000,000; umbrella $5,000,000; covered judgment $3,500,000. The CGL pays $1,000,000 and the umbrella pays the remaining $2,500,000 .

2. Drop-Down Coverage

When a claim is covered by the umbrella but not by the underlying, the umbrella "drops down" — after the insured satisfies the SIR . Example: The CGL excludes a personal-injury offense (e.g., advertising injury form gap) that the umbrella covers. On a $500,000 claim with a $25,000 SIR, the umbrella pays $475,000 .

3. Self-Insured Retention (SIR)

The SIR is the amount the insured pays out of pocket when the umbrella drops down because no underlying coverage applies. Typical SIRs run $10,000–$25,000 . Crucially, the SIR is not a deductible against ordinary excess claims — when the umbrella simply pays above an exhausted underlying limit, no SIR applies .

Required Underlying Limits (The "Schedule of Underlying")

An umbrella conditions its coverage on the insured maintaining specified underlying limits . If the insured carries less than required — or lets a policy lapse — the umbrella responds as though the required underlying were still in place , leaving the insured to fund the gap.

• Underlying Policy Typical Minimum Required
• Commercial General Liability $1,000,000 per occurrence / $2,000,000 aggregate
• Business Auto $1,000,000 combined single limit (CSL)
• Employers Liability (WC Part Two) $500,000 / $500,000 / $500,000

Trap: If the insured buys a $500,000 CGL when the umbrella requires $1,000,000, and a $2,000,000 loss occurs, the umbrella pays excess of $1,000,000 (the required amount) — the insured personally absorbs the $500,000 gap between actual and required underlying.

When to Choose Each

• Use an Umbrella when… Use Excess when…
• You want drop-down for gaps in underlying You only need higher limits
• Underlying has known coverage holes Underlying coverage is already comprehensive
• You want catastrophic + broadening protection Lowest premium is the priority
• Indicative Limits and Cost

• Umbrella Limit Typical Annual Premium (small/mid business)
• $1 million $500 – $1,500
• $5 million $1,500 – $4,000
• $10 million $3,000 – $8,000
• $25 million $8,000 – $20,000

Premiums are low relative to the limits because the underlying pays first ; umbrella losses are infrequent.

Common Exam Traps

Drop-down is the umbrella's signature — excess policies never drop down.

SIR applies only on drop-down , not on ordinary excess claims, and is distinct from a primary deductible.

Maintaining underlying limits is a condition — under-insuring the primary shifts the gap to the insured, not the umbrella.

Excess = follow-form — it cannot cover anything the underlying excludes.

Aggregate Erosion and the Maintenance Deductible

Umbrella coverage interacts with the aggregate limits of the underlying policies in a way candidates frequently miss. When an underlying aggregate (for example, the CGL $2,000,000 general aggregate) is exhausted by paid losses during the year , the umbrella generally drops down to apply over a maintenance amount — sometimes the per-occurrence underlying limit, sometimes a stated maintenance deductible — for further claims, rather than leaving the insured fully exposed. This is different from drop-down for an excluded peril (which triggers the SIR).

Distinguishing the two drop-down situations — aggregate exhausted (handled via the underlying/maintenance amount) versus claim excluded by the underlying (handled via the SIR) — is a precise, exam-tested point.

Personal Umbrella Parallels and Underlying Auto/Watercraft

The personal umbrella mirrors the commercial form for individuals, sitting above homeowners and personal auto. It likewise requires stated minimum underlying limits — commonly a homeowners liability of $300,000 and personal auto liability of $250,000/$500,000 (or a $300,000–$500,000 CSL) — and may require underlying watercraft or recreational vehicle liability if those exposures exist.

Like its commercial cousin, the personal umbrella can drop down to cover certain liabilities the underlying excludes (subject to the SIR), such as some personal-injury offenses (libel, slander) or worldwide liability, while excluding intentional acts, business pursuits, and the insured's own injuries. Recognizing that both commercial and personal umbrellas share the maintain-underlying condition, the drop-down/SIR mechanism, and broad excess limits ties this section to the personal-lines material elsewhere on the exam.
