Add new Boolean flag as a conditional field onto applicable CAT order events (MENO, MEOM, MEOT, MEOTS) to identify Short Sale orders originated or modified when relying on the bona fide Market Making exception under Rule 203(b)(2)(iii) of Regulation SHO.

The field is applicable to Market Makers on a security-by-security basis. When the BFMMFlag is populated with a value of true, the side field must be populated with a value of ‘SS’ or ‘SX’ and the accountHolderType value must be ‘O’.

This reporting supports the SEC’s requirement to report reliance on the bona fide market making exception in Regulation SHO, in connection with the SEC’s issuance of Release No. 34-98738. The compliance date for this reporting is July 1, 2025.
