| Name: | us-gaap:SwapMember |
| Documentation: | A forward-based contract in which two parties agree to swap streams of payments over a specified period. The payment streams are based on an agreed-upon (or notional) principal amount. The term notional is used because swap contracts generally involve no exchange of principal at either inception or maturity. Rather, the notional amount serves as a basis for calculation of the payment streams to be exchanged. |
