| As previously announced the next Front-end Clearing (FEC) application to be implemented, will be the Allocate and Claim System (ACS). The implementation of this new system will require firms to accommodate several enhancements. Please note the detailed information below: ELIMINATION OF THE 3270-BASED GIVE-UP SYSTEM (GUS) The ACS application will replace the existing 3270-based GUS. It will only be accessible through the CME Portal via the Internet. All current 3270 GUS users who will need to utilize the new ACS application should request Portal access as soon as possible. Training classes will be conducted during the month of October and November. A schedule will be published in the next two weeks. ELIMINATION OF GUSR BATCH FILES With the launch of ACS, we will eliminate all 80 byte "GUSR" files. The new application will be a real-time web- browser application, supporting a full range of real-time API message-based processing. This will require firms to utilize the current GUS-MQM messages for bookkeeping purposes. The specific message codes, in positions 1-3 of the TREX record are: TRX GCC record -- Loads to the carrying firm�s bookkeeping system when a trade is claimed TRX GCA record -- The offset record that loads to the executing firm�s bookkeeping system when a trade is accepted by the designated carrying firm.
Firms will not need to use fully functional GUS-API, but will need to process the above record types in place of the existing GUSR files. Real time GUS-MQM messages will be sent along with your other TREX messages such as GLOBEX and TES confirms. For those firms interested in using GUS-MQM to its fullest capacity, click on link http://www.cme.com/files/cm_gusapimsgtype.pdf to review all of the GUS-MQM message types. ELIMINATION OF MEMOADDS The new ACS system has been enhanced to eliminate the need to do MEMOADDS. All matched trades that were not marked for give-up may be viewed using the front-end clearing application on the Portal. A �G� indicator may be added to the record, which will be saved for five business days, to add the trade to ACS. Additional functionality is being added to MOS to provide the ability to route trades accepted on MOS to ACS. ELIMINATION OF TYPE 4 SUB-ALLOCATION RECORDS The new ACS system will route GCC messages instead of type 4 messages when a carry firm completes a sub-allocation. We ask that you review these requirements with your bookkeeping system provider to ensure that your processes will be ready upon implementation of ACS.
