If you requested an LEI through MEXEM and do not want it renewed at its annual renewal date, you would need to submit this request via the Message Center within Account Management at least two weeks in advance of your renewal date. Please note that certain exchanges need the submission of an LEI as a condition of accepting an order and if you do not manage an active LEI both opening and closing orders are subject to rejection. We therefore recommend that you review and close existing positions prior to terminating your LEI. See In what instances is an LEI required? for more details.
