As a reminder, on June 24, 2007, CME will list 4 NYMEX options contracts (NYMEX Crude Oil andNatural Gas Options and COMEX Gold and Silver Options) on CME Globex®. In addition, on the same date, market data for all NYMEX futures and options contracts traded on CME Globex will be transmitted via CME’s Market Data Platform (MDP). Ticker testing of NYMEX Futures and Options Market Data will be offered by CME as follows:

For Distributors with CME New Release Certification Connectivity

NYMEX options ITC 2.1 test data has been available in CME’s New Release Certification environment since May 21, 2007.  Distributors are encouraged to conduct their testing at their convenience prior to June 24.

For Distributors without New Release Certification Connectivity

Saturday, June 23, 2007 -- A test transmission is not planned; however, mock trading is scheduled to take place from 9:00 – 11:00 a.m. CST, and any distributors wishing to test during this period will be able to capture market data from the mock trading session.

To facilitate communications with support staff during the test, we have added a conference bridge number for market data distributors to dial into.  This conference bridge number will be available during testing on both remaining Saturday tests, and ask that distributors call in to confirm connectivity and receipt of market data.  The conference bridge information is:

            Domestic Dial-in Number:                  1.800.264.8432

            International Dial-in Number:              1.719.457.0337

            Participant Passcode:                        113507

Any connectivity issues that are identified during testing should be immediately reported to CME Enterprise Technology Operations at 312.930.8160.  If you have any feedback regarding this testing, please email mradecki@cme.com or kbrady@cme.com.
