Interpreting Aggregate Limits Key insights for vendor COI review

This guide provides practical insight into interpreting aggregate insurance limits on vendor Certificates of Insurance to ensure they align with your project requirements.

Why should I care about aggregate limits on a COI?

Aggregate limits are critical because they define the total capacity of a vendor's coverage. If multiple claims occur, the aggregate limit can be exhausted, leaving your organization exposed to potential risks. Understanding how to compare these limits against your requirements helps in assessing vendor suitability.

Operational Insight

Distinguishing Per-Project vs. General Aggregate

Many commercial general liability policies include a 'General Aggregate' limit. In construction and facilities management, it is often vital to request a 'Per Project' aggregate endorsement. This ensures that the limit applies specifically to your contract or project, rather than being shared across all of the vendor's work for every client they serve.
