Office of Supervisory Jurisdiction (OSJ)
A member firm must designate one or more of its offices as an Office of Supervisory Jurisdiction. An OSJ is an office that demands special supervisory attention from the firm because FINRA deems that the activities conducted there have particular regulatory significance, or because the member firm itself may believe it is prudent or necessary based on certain FINRA guidelines.
FINRA Rule 3110 states that if the following critical activities occur in an office, that office must be designated an OSJ:
- • Order execution or market making
- • Structuring of public offerin
