This advisory notice provides links to the updated TREX layout documents that will be effective on Monday, November 24, 2003, with the initial implementation of the CBOT-CME Common Clearing Link.

These documents describe the TREX record format as it is currently used for CME products, and as it will be used for CBOT products clearing through the Common Clearing Link, beginning on that date.  As can be seen, the TREX usage for trades in CBOT products and for trades in CME products will be almost identical.

The layout is provided in two different formats:  a clean format, without markup, and a marked-up format (with "tracking of changes" turned on) showing exactly how the document has been modified.

For the clean format TREX layout ...
