    • Clearing firms may use FIXML Assignment Report files to automate the option assignment process, or to automate reconciliation of CME Clearing assignments, to bookkeeping assignments. These files are found in a clearing firm’s “Outgoing” FTP directory, if they have requested that the files be created daily.
       
      Beginning trade date Monday, February 10, 2014, the sign of the Settlement Amount value for FIXML assignment messages within the FIXML assignment file will now reflect the true direction of money flow for the assignment. Previously, this number had always been positive (greater than zero, which in all other CME Clearing files is a “Collect” amount). In the vast majority of assignments, the monetary impact is a negative value (less than zero, a “Pay” amount). Beginning with the Monday, February 10, 2014 clearing cycle, the correct value will appear in these FIXML messages. The Settlement Amount is found within the “SETL” Amount Type block of the FIXML messages.
       
      There are NO CHANGES to any exercise or assignment reports or other text files. This change relates specifically to FIXML assignment report files that use the naming convention “AsgnRpt-CMF_XXX_PA_YYY-EA-#.xml”, where:
       
      ·         XXX is the Clearing Member ID
      ·         YYY is the Clearing Member’s Position Account in CME Clearing
      ·         # is the exercise/assignment cycle for the day.
       
      A sample Assignment Report is shown on the following page.
