NYMEX to List Crude Oil MACI Index and Crude Oil Backwardation–Contango Index Futures Contracts on the CME Globex® Electronic Trading Platform – Effective Sunday, February 10, 2008

Attention NYMEX Market Data vendors,

As a reminder, starting trade date February 11, 2008, the Exchange will make available for trading two new financially settled Index futures, NYMEX Crude Oil MACI Index and NYMEX Crude Oil Backwardation-Contango Index, on CME Globex®, the NYMEX Trading Floor, and NYMEX ClearPort® Clearing.  In addition, TAS (‘Trade at Settlement’) contracts in both Index futures will be available on CME Globex® and the NYMEX Trading Floor.  Block Trades can also be submitted for each product via the NYMEX Trading floor or NYMEX ClearPort® Clearing.

Both products will only offer one contract initially: NYMEX Crude Oil MACI Index- a Jan 2011 contract; NYMEX Crude Oil Backwardation-Contango Index- a Dec 2010 contract.

Both products will eventually support up to three contract months each.  For NYMEX Crude Oil MACI Index the Exchange will list a Jan 2012 contract on the second business day of January 2009, then a Jan 2013 contract on the second business day of January 2010.  For NYMEX Crude Oil Backwardation-Contango Index the Exchange will list a Dec 2011 contract on the second business day of January 2009, then a Dec 2012 contract on the second business day of January 2010.  Please note- Calendar Spreads will be supported when more than one contract becomes tradable for each product.

It is important to note the following:

• Settlement Messages for contracts in these products will be available only on the NYMEX ITC 2.1 Multicast feed. Though sharing the same settlement price for a particular contract, an ITC 2.1 settlement message (Category Code Q) will be published for both the Globex® Product Symbol and the NYMEX Floor Product Symbol (i.e., two settlement messages will be disseminated for each NYMEX Crude Oil MACI symbol; one for XC, one for XCN. Both messages will contain the same settlement price.).

• Open Interest and Actual Volume (Category Code I) messages will not be made available for the Globex® Product symbols.  Instead, the Open Interest and Actual Volume messages will only be disseminated for the floor symbols over the NYMEX ITC 2.1 Multicast feed, and will include combined figures (Floor + Globex).

• Globex-specific Summary (Category Code J) messages will appear on the NYMEX ITC 2.1 Multicast feed with Session ID ‘G’, and will include the Globex® Product Symbol. Combined Summary (OJ) messages will also be sent over the NYMEX ITC 2.1 Multicast feed, will be distinguishable by a blank Session ID, and will include the NYMEX Floor Product Symbol.
