Frequently Asked Questions

An occurrence policy covers events that happen during the policy period, regardless of when the claim is filed. A claims-made policy covers claims reported during the policy period, regardless of when the event occurred. Most construction GL policies are occurrence-based, while professional liability policies are often claims-made.

Additional insured status extends the named insured GL coverage to the additional insured for liability arising from the named insured operations. This gives the additional insured a direct right to coverage under the policy, including a defense obligation, without having to rely solely on contractual indemnification.

An umbrella policy provides broader coverage than underlying policies and may cover claims not covered by primary policies (drop-down coverage). An excess policy follows the same terms and conditions as the underlying policy and only adds additional limits. In practice, the terms are sometimes used interchangeably in the construction market, but true umbrellas offer broader protection.
