In 1987, ISDA established three documents: (i) a standard form control agreement for U.S. dollar interest rate swaps; (ii) a standard-master contract for multi-currency interest rate and exchange rate swaps (known as the «1987 ISDA Executive Contract»); and (iii) definitions of interest rates and currencies. The framework contract also helps to reduce litigation by providing significant resources that define its contractual terms and explain the intent of the contract, thus preventing litigation from beginning and providing a neutral resource for interpreting standard contractual terms. Finally, the framework agreement provides significant assistance in managing risks and credit for the parties. The main credit support documents in English law are the 1995 credit support annex, the 1995 credit support instrument and the 2016 credit support annex for the margin of change. English credit support laws provide for property guarantees, while English law provides for the granting of an interest rate on the value of the property through transferred security. The 2016 Credit Support Schedule for Variation Margin was specifically created to enable the parties to meet their commitments to exchange margin of change worldwide, including EMIR in Europe and Dodd-Frank in the United States of America. The English Credit Support Annexes laws are confirmations, and the transactions they have formed are transactions, within the framework of the master`s contract and therefore part of the single agreement with the master contract. On the other hand, the English legal act Credit Support Deed is a separate agreement between the parties. It is the contractual framework in which repurchase/sale transactions are carried out and contractually obliges both parties to apply a netting in the event of a late payment for all transactions and guarantees in progress. As of December 31, 2016, the group had signed the CSA part of the ISDA management contract with 25 counterparties (compared to 24 in 2015). At the same time as the timetable, the framework agreement defines all the general conditions necessary for the proper distribution of the risks of transactions between the parties, but does not contain specific terms and conditions for a particular transaction.
