Aggregate Limit (Umbrella)
The maximum total amount the umbrella or excess policy will pay for all claims combined during the policy period.
What It Is
The aggregate limit in an umbrella or excess liability policy is the maximum total amount the policy will pay for all covered claims combined during the policy period, regardless of how many occurrences trigger coverage. Once the aggregate is exhausted, the umbrella provides no further coverage for the remainder of the policy period.
Most commercial umbrella policies carry an aggregate limit equal to the per occurrence limit, though some have higher aggregates. For example, a $5M umbrella may have a $5M per occurrence and $5M aggregate, meaning a single $5M occurrence exhausts the entire policy for the year. Some carriers offer $5M per occurrence with a $10M aggregate, providing capacity for multiple large claims.
The aggregate interacts with the underlying policy aggregates. If the underlying CGL aggregate is exhausted mid-year, subsequent claims that would normally be covered by the CGL now erode the umbrella from the first dollar (above the SIR), consuming the umbrella aggregate more quickly.
Why It Matters for Brokers
Brokers must monitor aggregate erosion throughout the policy period—not just at renewal. A client who suffers multiple claims early in the policy year may have significantly reduced or exhausted umbrella limits for the remainder of the year. When underlying aggregates are exhausted, the umbrella erodes even faster because it responds from the first dollar above the SIR. Brokers should recommend aggregate restoration or higher aggregate limits for clients with high claim frequency.
Real-World Example
A property management company has a $2M CGL aggregate and a $5M umbrella with a $5M aggregate. Three slip-and-fall claims totaling $1.8M exhaust most of the CGL aggregate by July. In September, a $3.5M claim occurs. The CGL pays only $200,000 (remaining aggregate). The umbrella pays $3.3M, reducing its remaining aggregate to $1.7M. A fourth incident in November results in a $2.5M claim. The CGL aggregate is exhausted ($0 remaining). The umbrella pays only $1.7M (remaining aggregate), and the insured is $800,000 short.
Common Mistakes
- 1Not tracking aggregate erosion during the policy year—a major claim early in the year can leave the insured with insufficient protection for the remainder.
- 2Assuming the umbrella aggregate is in addition to the underlying aggregate—when the underlying aggregate is exhausted, the umbrella picks up from the SIR, eroding its own aggregate faster.
- 3Not considering aggregate restoration endorsements or higher aggregate limits for clients with high claim frequency or multiple locations.
How brokerageaudit.com Handles This
brokerageaudit.com's Policy Checker tracks aggregate limits across all liability layers and monitors reported claims against remaining aggregates. The system sends alerts when aggregates are eroded by more than 50% before the policy period ends, recommending aggregate restoration options or increased limits at renewal. The platform displays remaining aggregate capacity in real-time for each layer of the liability tower.
