The most common endorsement modification to a CGL policy is known as what?

The most common endorsement modification to a Commercial General Liability (CGL) policy is referred to as a known damage endorsement. This particular endorsement is important because it is designed to exclude coverage for specific known incidents or circumstances that have already occurred before the policy took effect. By defining these known damages, the endorsement allows insurers to manage their risk exposure more effectively.

In practical terms, the known damage endorsement prevents claims related to incidents that the insured is already aware of, ensuring that they cannot seek coverage for those issues under the new policy. This is a common approach in insurance to limit liability and ensure that the policy responds only to unanticipated issues that arise after the coverage period begins.

Other options such as a new businessowners policy, a liability exclusion, or an ongoing injury endorsement may exist within the realm of insurance but do not represent the specific and common modification made to a CGL policy in the context of known damages. Each of the other options serves different purposes, such as providing coverage tailored to small businesses or setting exclusions for certain liability coverages, but they do not focus on the specific aspect of addressing previously known incidents, which is central to the known damage endorsement's function.
