In response to firms’ requests to improve the option assignment process, CME Clearing is pleased to introduce a new file of FIXML Assignment Report messages that will be available to back-offices daily, immediately following exercise and assignment processing for CME and CBT options (currently run at 5:30 p.m. for CBT Flex options, and averaging between 8:30 – 9:00 p.m. for the balance of options).  This file can be read by firm bookkeeping systems and act as a trigger to automatically invoke internal customer account assignment processing.  In addition to automation, an added benefit is that customers can be informed of assignments and resulting market exposure on a timelier basis.
