• A catastrophe bond is a derivative debt investment vehicle issued by insurers and reinsurers that is designed to raise investor capital to cover catastrophic losses. Cat bonds are issued to cover either a specific event (such as an earthquake in Japan) or the possibility of a certain amount of loss associated with hurricane activity in a particular geographic location (such as the Gulf Coast). Unlike traditional highly leveraged reinsurance (i.e., reinsurance limits sold are many times the reinsurer’s capital), cat bonds are not leveraged because their value is equal to the sum of insurance limits sold.
