Capacity limits how much exposure an insurer can assume, often adjusted by portfolio concentration, retention, and catastrophe load.
Coverage intent
It determines whether an account can be fully placed in one policy program or must be shared, co-insured, or reinsured.
Underwriting and policy mechanics
Capacity decisions rely on:
- Line size versus company appetite.
- Capital and reinsurance protection.
- Correlation of exposures across industry and geography.
- Event attachment and accumulation controls.
Claims logic
Claims treatment is linked to placed limits. If a loss exceeds capacity layers, settlements follow the placement stack from primary insurer to excess participants.
Practical question
Can an insurer decline coverage simply because risk is too large even if the customer is otherwise insurable?
Yes. Capacity is as much a capital and portfolio decision as it is a risk-quality decision.
