15.2 Commercial Umbrella and Excess Liability

Umbrella vs. Excess - The Core Distinction

Both a commercial umbrella and a commercial excess policy sit on top of primary liability coverage, but they are not the same animal, and the exam loves the contrast.

• A commercial umbrella does two jobs: it provides excess limits over scheduled underlying policies AND it can provide broader (drop-down) coverage for claims the umbrella covers but the underlying policy excludes.
• A commercial excess (or 'following form') policy only does the first job: it adds limits over the underlying policy and follows the underlying terms exactly. If the underlying excludes a loss, the excess policy excludes it too.

Quick Answer: Umbrella = more limit PLUS broader coverage; excess = more limit ONLY, matching the underlying form.

The umbrella's broadening function is what makes it valuable, and it is the reason umbrellas require a self-insured retention (SIR) for losses not covered by underlying insurance.

How the Three Layers Stack

Self-Insured Retention (SIR): When the umbrella covers a loss the underlying policy does NOT (a true drop-down), the insured first pays the SIR - commonly $10,000 or $25,000 - before the umbrella responds. The SIR is the umbrella's deductible for those gap claims; it does NOT apply when the umbrella is merely sitting excess of a covered primary loss.

Maintenance warranty: The umbrella requires the insured to keep the scheduled underlying limits in force. If the insured lets the CGL lapse or buys a lower limit, the umbrella treats the underlying as if it were still at the required limit - the insured eats the difference.

Worked Example - Drop-Down vs. Excess

ABC Manufacturing carries a $1,000,000 CGL occurrence limit and a $5,000,000 commercial umbrella with a $10,000 SIR.

Scenario 1 - Excess loss (covered by both): A covered products-liability judgment totals $3,500,000. The CGL pays its $1,000,000 limit; the umbrella pays the remaining $2,500,000. No SIR applies because the underlying policy responded.

Scenario 2 - Drop-down (covered by umbrella only): A worldwide advertising-injury claim is excluded by the CGL but covered by the umbrella. The umbrella drops down. ABC first pays the $10,000 SIR, then the umbrella pays the loss above the SIR up to its $5,000,000 limit.

Common trap: candidates apply the SIR to Scenario 1. The SIR exists only for true gap claims; when the underlying policy pays, the umbrella simply sits above it.

Following-Form Excess

A following-form excess policy in Scenario 1 would pay the same $2,500,000. But in Scenario 2 it would pay nothing, because it follows the CGL exclusion. That single difference - drop-down capability - is the heart of the umbrella-vs-excess question.

Underlying Schedule and the Defense-Cost Question

The umbrella's declarations list a schedule of underlying insurance (CGL, business auto, employer's liability) with required limits. The umbrella sits excess of those scheduled limits and drops down only for covered-but-not-underlying claims, subject to the SIR. Defense treatment differs by form: many umbrellas provide defense only when no underlying policy defends (a true drop-down), and defense may be inside or outside the umbrella limit depending on wording.

Trap: If the insured fails to maintain the scheduled underlying limits (lets a CGL lapse or lowers it), the umbrella still treats the underlying as if it were at full required limits - the insured eats the gap. The SIR applies only to drop-down claims, never to a loss the underlying policy paid.

Drop-Down vs. Following-Form - the Decisive Difference

The single distinction the exam hammers is drop-down capability. An umbrella both adds limits over the underlying and drops down (subject to the SIR) for claims the underlying excludes. A following-form excess policy adds limits only and mirrors the underlying exclusions exactly.

Trap: Apply the SIR only to true drop-down (gap) claims, never to a loss the underlying policy paid. And if the insured fails to maintain the scheduled underlying limits, the umbrella acts as if those limits were still in force - the insured absorbs the shortfall. Drop-down is what makes the umbrella worth more than plain excess.

Self-Insured Retention vs. Deductible on the Umbrella

The umbrella's SIR is not a deductible. With an SIR the insured pays the retained amount directly on a drop-down claim before the umbrella responds and, on many forms, the insured also handles the defense below the SIR. With a deductible, the insurer pays and then bills the insured back. The SIR applies only to true gap (drop-down) claims, never to a loss the underlying policy already paid.

Trap: Candidates apply the SIR to an ordinary excess loss where the underlying policy paid - wrong. The SIR exists for the drop-down scenario (umbrella covers it, underlying does not), which is the umbrella's defining advantage over a following-form excess policy.
