An ISDA Master Agreement is the standard document regularly used to govern over-the-counter derivatives transactions. The agreement, which is published by the International Swaps and Derivatives Association (ISDA), outlines the terms to be applied to a derivatives transaction between two parties, typically a derivatives dealer and a counterparty. The ISDA Master Agreement itself is standard, but it is accompanied by a customized schedule and sometimes a credit support annex, both of which are signed by the two parties in a given transaction.
