A credit support appendix (CSA) is a document that sets out the conditions for the parties to make guarantees available in derivatives transactions. It is one of four parts of a standard contract or master`s contract developed by the International Association of Swaps and Desivatives (ISDA). A master`s contract is required for derivatives trading, although the CSA is not required in the overall document. Since 1992, the framework agreement has been used to define the terms of derivatives trading and make them mandatory and enforceable. Its publisher, ISDA, is an international trade association for participants in futures markets, options and derivatives. The framework agreement and timetable define the reasons why one party may impose the closure of covered transactions due to the appearance of a termination event by the other party. Standard termination events include defaults or bankruptcy. Other closing events that can be added to the calendar include a downgrade of credit data below a specified level. ISDA`s governing agreements are required between two parties that trade derivatives under an over-the-counter agreement negotiated privately, not through an established exchange. Most derivatives trading is done through private agreements. Most multinational banks have ISDA master agreements. These agreements generally apply to all branches engaged in currency, interest rate or option trading.
Banks require counterparties to sign an exchange agreement. Some also require exchange agreements. While the ISDA master contract is the norm, some of its terms and conditions are changed and defined in the accompanying schedule. The schedule is negotiated, either to cover (a) the requirements of a given hedging transaction or (b) a current business relationship. Sometimes a credit support appendix (CSA) also accompanies the Master. The CSA allows both parties to reduce their credit risk by defining the conditions under which they must provide each other with guarantees.
