Commercial Umbrella & Excess Liability
Key Takeaways
- A commercial umbrella provides high excess limits above primary policies and can drop down to cover some claims the primary excludes or after underlying aggregates are exhausted.
- A self-insured retention applies only to claims the umbrella covers but the underlying policy does not; no SIR applies to excess over a covered claim.
- The insured must maintain stated underlying limits; failing to do so leaves the insured, not the umbrella, to absorb the gap.
- Excess liability simply adds limits following the primary form, without the umbrella's broadening drop-down function.
Layering Liability Limits
A commercial umbrella policy provides high-limit liability coverage that sits above the insured's primary liability policies (CGL, commercial auto, employers liability) and can also drop down to provide coverage broader than the underlying policies in some situations. Excess liability simply adds limits on top of a primary policy following its terms. The exam tests the three functions of an umbrella and the role of the self-insured retention.
| Function | What it does |
|---|---|
| Excess over underlying | Pays after the primary limit is exhausted, following form |
| Broader coverage (drop down) | Covers some claims the primary excludes, subject to a self-insured retention |
| Replace exhausted aggregates | Continues coverage after underlying aggregates are used up |
The Three Functions of an Umbrella
First, the umbrella provides excess limits: when a covered claim exceeds the underlying CGL or auto limit, the umbrella pays the excess up to its own high limit. Second, it can provide broader coverage than the underlying policies, paying some claims the primary excludes; for these gap claims the insured must satisfy a self-insured retention (SIR), a deductible-like amount the insured pays before the umbrella responds, because there is no underlying policy to pay first.
Third, when an underlying aggregate is exhausted by other claims, the umbrella can drop down to act as primary for new claims. The exam tests these three functions and especially the role of the SIR for coverage the underlying policy does not provide.
Required Underlying Limits
An umbrella requires the insured to maintain stated underlying limits on the primary policies (for example, a minimum CGL each-occurrence and aggregate, auto liability, and employers liability). If the insured fails to maintain the required underlying coverage, the umbrella treats the underlying as if it were still in place, meaning the insured, not the umbrella, absorbs the gap. The exam tests that the umbrella does not fill in for underlying limits the insured was supposed to carry but did not.
Self-Insured Retention
The self-insured retention applies only to claims the umbrella covers but the underlying policy does not. For claims the underlying covers, the umbrella pays above the underlying limit with no SIR. For a claim outside the underlying coverage, the insured pays the SIR and the umbrella then responds. Distinguishing when the SIR applies (umbrella-only coverage) from when it does not (excess over a covered claim) is a precise exam point.
Applying Umbrella Concepts
When a scenario describes a liability claim exceeding the primary limit, the umbrella pays the excess. When the claim is one the primary policy excludes but the umbrella covers, the insured pays the SIR and the umbrella responds. When other claims have exhausted the underlying aggregate, the umbrella drops down to respond as primary. And when the insured failed to carry required underlying limits, the umbrella pays only what it would have if those limits were in force, leaving the insured to absorb the difference.
Reasoning through these four situations, excess, drop-down for broader coverage with an SIR, drop-down for exhausted aggregates, and the maintenance-of-underlying rule, lets you answer the commercial umbrella questions the exam presents.
A commercial umbrella covers a liability claim that the underlying CGL specifically excludes. What must the insured satisfy before the umbrella pays?
If an insured fails to maintain the underlying limits the umbrella requires, what happens when a large claim occurs?
The Three Umbrella Functions and the SIR
A commercial umbrella performs three functions, and questions test which applies. First, it pays excess over the underlying CGL, auto, or employers liability when a covered claim exceeds the primary limit. Second, it provides broader coverage than the underlying policies, paying some claims the primary excludes; for these the insured must satisfy a self-insured retention (SIR), because no underlying policy pays first. Third, when an underlying aggregate is exhausted by other claims, the umbrella drops down as primary for new claims.
The SIR applies only to claims the umbrella covers but the underlying does not. For excess over a covered claim, the umbrella pays above the underlying limit with no SIR. Distinguishing these two situations is a precise exam point.
| Situation | Umbrella response |
|---|---|
| Claim exceeds primary limit | Pays excess (no SIR) |
| Claim primary excludes | Pays after SIR |
| Underlying aggregate exhausted | Drops down as primary |
| Required underlying not maintained | Pays only as if it were |
The maintenance-of-underlying condition requires the insured to keep stated underlying limits in force; if the insured fails to do so, the umbrella pays only what it would have had those limits been in place, leaving the insured to absorb the gap. Excess liability, by contrast, simply adds limits following the primary form, without the umbrella's broadening drop-down function.
When a scenario describes a claim above the primary limit, an excluded claim the umbrella covers, an exhausted aggregate, or a failure to carry required underlying limits, match it to the correct umbrella function and remember when the SIR applies.
Distinguish the three umbrella functions: paying excess over a covered underlying claim (no self-insured retention), providing broader coverage for a claim the underlying excludes (the insured first pays the self-insured retention), and dropping down as primary when an underlying aggregate is exhausted. The maintenance-of-underlying condition requires the insured to keep the required underlying limits in force; if it fails to, the umbrella pays only as if those limits existed, leaving the insured to absorb the gap.
Excess liability simply adds limits following the primary form, without the umbrella's broadening drop-down function.
