A clearing house that enables parties to a transaction to substitute, through novation or otherwise, the credit of the clearing organisation for the credit of the parties. The term Derivatives Clearing Organisation was defined under the Commodity Futures Modernization Act of 2000 (CFMA). The DCO must register with the Commodity Futures Trading Commission (CFTC) before it can begin providing such services. The CFTC has issued several rule proposals related to DCOs, including: i) Financial resource requirements for derivatives clearing organisations and 'systemically important' derivatives clearing organisations (SIDCOs) ii) Governance, conflict of interest mitigation and risk management requirements.
