The risk that a counterparty to a transaction will not pay when the triggering event occurs. The risk in the case of catastrophe bonds is low. The proceeds of the bond are invested in safe securities such as US Treasury Bonds and held in trust by the bankruptcy-remote SPV or a special trust. If the triggering event occurs the insurer is permitted to withdraw funds from the trust. In return the investors receive the one-year Treasury bill rate plus a premium rate.
