    • Please be advised that effective this Monday, September 20, 2010, CME Clearing will make the following two enhancements to the Clearing FIXML API.
       
       
      1)     The CPCAllocID attribute will no longer be populated in the main block of outbound TrdCaptRpt confirmations to clearing firms via the Clearing FIXML API. The attribute is a clearing defined field that was intended only to be sent to firms writing to the ClearPort FIXML API for submission of Credit Default Swaps to ClearPort. This attribute was populated exclusively on Credit Default Swap messages and no others.
       
       
      2)     The ClOrdID2 attribute, which represents the CTR regulatory field for pit trades, will be enhanced to support up to 6 alphanumeric characters on inbound FIXML messages from Clearing firms. CME Clearing will continue to store only 4 alphanumeric characters as is the case in TREX by truncating after the leftmost 4 characters.
       
       
      The above changes have been implemented in the CME New Release region and have been tested internally and by firms. If you have any questions or require further information please contact CME Clearing at 312-207- 2525 or ccs@cmegroup.com.
