Contractual agreements that provide protection against a credit event on one or more reference entities or financial assets. The nature of a credit event is established by the protection buyer and protection seller at the inception of a transaction, and such events include bankruptcy, insolvency or failure to meet payment obligations when due. The buyer of the credit derivative pays a periodic fee in return for a payment by the protection seller upon the occurrence, if any, of a credit event. Credit derivatives include credit default swaps, total return swaps and credit swap options.
