Through hardwiring, ISDA is incorporating into its standard documentation the auction settlement of contracts after a default or other credit event on a company referenced in credit default swap transactions.

This is implemented by way of a supplement to the 2003 ISDA Credit Derivatives Definitions.  The Auction Supplement amends the ISDA CDS Definitions to incorporate the CDS settlement auction terms that have to date been included in the auction protocols. It also includes provision for the ISDA Determinations Committee, which going forward will make binding determinations for issues such as whether a Credit Event has occurred; whether an auction will be held; and whether a particular obligation is deliverable.

The amendments made by the Auction Supplement apply to transactions entered into going forward.  ISDA has also published a Protocol to facilitate the amendment of existing transactions to reflect the new terms.

The Protocol opens for adherence on March 12, 2009 and closes on April 7, 2009. In accordance with paragraph 2(e) of the Protocol, there will be a Subsequent Adherence Period for the Protocol, which will open on July 14, 2009 and close on July 24, 2009. The Subsequent Implementation Date (as defined in paragraph 2(e)(ii) of the Protocol) will be July 27, 2009. Parties may only adhere to the Protocol during the Subsequent Adherence Period by adhering to the 2009 ISDA Credit Derivatives Determinations Committees, Auction Settlement and Restructuring CDS Protocol (the "Small Bang Protocol"). Please see the relevant webpages relating to the Small Bang Protocol for details.
