As previously announced, on Friday, September 23, 2005, CME will launch trading in its first products with a three-byte clearing product code.  In preparation for this, on Monday, September 12, 2005, we will implement format changes to support these expanded product codes in the "edit" file and the settlement price files produced daily.  

For the detailed description of these changes, please see Clearing Advisory 05-134, published on July 1st, at http://www.cme.com../files/Chadv05-134.pdf.

For the updated file layouts, please see http://www.cme.com/clearing/cm/stan/recolayout1013.html.
