Several Member Firms have requested that we no longer send Reversal records back to books when the new Reversal feature in the GUS system is used. As you know, GUS reversals are now initiated by the Executing firm and accepted by the Carry firm.

To this end, effective at the start of business Friday, July 13, 2001 we would like to eliminate Reversal records from the GUSR routing files.

Please take a moment and e-mail foweimri@cme.com to let us know if this change would cause any problems for your bookkeeping operations, and hence, necessitate a delay in its implementation.

If you have any questions, please call Farris Oweimrin at (312)-648-4780.
