Upon request of the Clearing House, Clearing Members shall obtain the information required by this Rule regarding the ownership and control of positions (whether assumed or entered into on any Relevant Market or elsewhere) within any Omnibus Account and any Sub-Account of any Omnibus Account. Provided that if the Omnibus Account Holder does not want the identity of any Sub-Account holder to be disclosed to its carrying Clearing Member, the Omnibus Account Holder may apply to the Clearing House for a special identification for the Sub-Account thereof for reporting positions (whether assumed or entered into on any Relevant Market or elsewhere) covered within this Rule through its carrying Clearing Member.
