Please be informed, effective with the Globex trading session beginning on Sunday, April 30, 2006 (for trade date Monday, May 1), the clearing system will suppress the display of opposite firm and opposite broker data on the bookkeeping TREX confirm message and on any subsequent change confirmation messages.  This change will apply to Globex trades on CME products only.

Instead of the actual contra-party data, firms will see “999” followed by two spaces in the opposite firm field, in position 76-80 of the TREX main block.  The opposite broker field, position 81-85 of the TREX main block, will contain "9999" followed by a space.

If you have any questions or would like to receive sample messages, please call the Clearing House at 312-207-2525.
