The ISDA Master Agreement, published by the International Swaps and Derivatives Association, is the most commonly used master service agreement for OTC derivatives transactions internationally. It is part of a framework of documents, designed to enable OTC derivatives to be documented fully and flexibly. The framework consists of a master agreement, a schedule, confirmations, definition booklets, and credit support documentation. Although it is often viewed as a tool for banks and financial institutions, the Master Agreement is widely used by a wide variety of counterparties.
