A method of creating and trading corporate debt security derivative investment instruments on an exchange, as well as a trading facility for trading such derivatives, is disclosed. Corporate debt security derivative investment instruments are created by identifying a credit rating service that includes a plurality of risk categories. Unique monetary values are mapped to risk categories and an entity rated by the credit rating service is identified. A corporate debt security derivative investment instrument is then created whose value is determined at least in part by the monetary value to which the risk category associated with the rated entity is mapped.
