Per Occurrence Limit (Umbrella)
The maximum amount the umbrella or excess policy will pay for any single occurrence or accident, regardless of the number of claimants.
What It Is
The per occurrence limit in an umbrella or excess liability policy is the maximum amount the policy will pay for all claims arising from a single occurrence—one accident, one event, or one continuous exposure. This limit applies regardless of how many individuals are injured, how many claimants file suits, or how many underlying policies are involved.
Umbrella per occurrence limits are typically available in increments of $1M, $2M, $5M, $10M, $15M, $20M, and $25M. The per occurrence limit is separate from and works independently of the aggregate limit. Each occurrence has its own limit available, subject to the overall aggregate.
The per occurrence limit attaches above the underlying per occurrence limits. If the underlying CGL has a $1M per occurrence limit and the umbrella has a $5M per occurrence limit, the total available coverage for a single occurrence is $6M ($1M underlying + $5M umbrella). For the umbrella to pay, the underlying $1M must first be exhausted.
Why It Matters for Brokers
Selecting the appropriate per occurrence umbrella limit is one of the most critical decisions in a commercial insurance program. Underestimating the exposure can leave a business financially devastated by a single catastrophic event. Brokers should evaluate worst-case scenarios—multi-vehicle accidents, structural collapses, product recalls, environmental incidents—and recommend limits sufficient to survive those events.
Real-World Example
A general contractor with a $1M CGL and a $5M umbrella causes a scaffolding collapse that injures 8 workers and 3 pedestrians. Total claim: $7.8M. The CGL pays $1M (per occurrence limit). The umbrella pays $5M (per occurrence limit). The contractor is $1.8M short. If the broker had recommended a $10M umbrella (approximately $3,200 more in annual premium), the entire $7.8M claim would have been covered. The $3,200 annual savings cost the contractor $1.8M.
Common Mistakes
- 1Selecting umbrella limits based solely on what similar businesses carry rather than analyzing the specific insured's worst-case exposure scenarios.
- 2Not considering that a single occurrence can involve multiple claimants—a bus accident, building collapse, or product defect can generate dozens of claims from one event.
- 3Confusing per occurrence and aggregate limits and not understanding that the aggregate may cap total annual payments below the per occurrence limit multiplied by the number of potential occurrences.
