Notes:
- The File Identifier allows the specification of a code to designate which file of the day this is. Most all exchanges will simply populate this field with FC.
- Fields beginning with the clearing or customer code in byte 24 are new, and have been added to allow the specification of a particular performance bond rate ID for which this file pertains. For example, if it is desired to provide separate SPAN risk parameter files for different account types, and/or to provide separate files for initial versus maintenance requirements, these fields allow the designation of the account type and the rate class for which this file pertains. If these fields are blank, null, or not present due to truncation of blanks at the end of the record, they should be defaulted as shown above.
