Policy underwritten on either a monoline primary insurance or monoline excess insurance basis that will allow the purchaser to increase the limits of liability coverage above that of policies already purchased as well as fill gaps in liability coverages. These policies usually provide liability protection on a worldwide basis to include coverage for bodily injury, property damage, products-completed operations, premises and operations, and personal injury. The period for claims reporting can be on a fixed or unlimited basis. Legal defense expenses and other supplementary expenses can be included within the policy limits or can be in addition to the policy limits. An endorsement can be added to provide coverage for known circumstances, thereby permitting the purchaser to retroactively add additional limits of coverage for current evolving liability situations. In addition, this policy can provide coverage for residual liability exposures by focusing on a particular risk.
