Reminder: Enhanced Execution Reports Issue  
CME has become aware of an issue with the new Enhanced Execution Reports, launched March 25, 2007.

Customers using a front-end trading application that leverages the new FIX tag 393 TotalNumSecurities and tag 442 - MultiLegReportingType, in Fill and Trade Cancellation Notices, will receive inaccurate fill information for implied spread orders when one or more legs are matched in an Implied Out market.

In this scenario, customers will receive execution reports for the spread and associated legs where tags 393 and/or 442 indicate one or more legs have not been filled, although they have been.

CME recommends that customers disable this functionality or revert to prior software versions that ignore these two tags until CME has resolved this issue. CME will send a customer notice as soon as the tags are corrected. Please contact CME Globex Account Management with any questions or concerns at 312.634.8700; or in Europe at 44.20.7796.7100.

More information on the new FIX tags 393 and 442, and the Enhanced Execution Reports, is available online.

Reminder: NYMEX Products on the CME Market Data Platform  
Effective Sunday, May 6, 2007, CME is decommissioning the legacy NYMEX market data channel (20) on the CME Market Data Platform.

Since the introduction of NYMEX futures and spreads on the CME Globex platform, market data messaging rates on the CME Market Data Platform NYMEX channel (20) have steadily increased, recently reaching peaks greater than 3 mbps. To better manage bandwidth utilization, CME leveraged the scalability of the CME Market Data Platform and introduced three new channels for NYMEX and COMEX ^® products.

Complete information on the three new NYMEX and COMEX channels on the CME Market Data Platform, including the products assigned to each channel, is available online.

More information on NYMEX and COMEX products on the CME Globex platform is available at www.nymexoncmeglobex.com.
