Under the CBOT/CME Common Clearing Link arrangement, CBOT Large Trader Position Reporting will change to be consistent with the record format that firms and service bureaus currently use to submit large trader positions to both the CME and CFTC. (Refer to Exhibit I.) This notice describes the upcoming changes that will be made to accommodate the Common Clearing Link implementation.

Please view the attached Common Clearing Link Upadet Notice   for more information.
