Business Insurance

Occurrence Policy

Occurrence-based policies provide permanent coverage for events that took place while the policy was active, even if the claim is made years after the policy expires.

Definition

An occurrence policy covers bodily injury or property damage that occurs during the policy period, no matter when the claim is actually made or filed — even if the policy has long since expired. This provides lasting protection: a general contractor insured under an occurrence policy in 2018 would still have coverage if a 2018 construction defect is discovered and claimed in 2025. General liability and commercial auto policies are almost universally written on an occurrence basis, and many contracts specify occurrence form coverage as a requirement. The trade-off compared to claims-made policies is that occurrence policies tend to carry slightly higher premiums because the insurer takes on long-tail exposure for latent claims that may emerge years after the policy year. Long-tail liability lines — such as environmental liability and medical malpractice — often are not available on an occurrence basis in standard markets because the discovery-to-claim timeline can stretch decades. When comparing occurrence vs. claims-made policies, businesses should evaluate the nature of their work, the potential latency of claims, and the availability and cost of tail coverage before selecting a policy form.
