Concerning linked-market transactions, how do NFA assessment fees apply to futures positions executed on a foreign exchange to be offset against positions executed on a domestic exchange and vice versa?

Any futures transaction that is carried as a CME trade by an FCM Member for the account of a customer (except trades which under Bylaw 1301(b) are not assessable) will be subject to an NFA assessment fee upon completion of the round-turn even though one or both sides of the round-turn may have been actually executed on SIMEX. Any transaction that is carried as a SIMEX trade by an FCM Member for the account of a U.S. customer (except trades which under Bylaw 1301(b) are not assessable) will be subject to an NFA assessment fee. Any trade that is executed on the CME but is transferred to a SIMEX member and the SIMEX clearing house through the Mutual Offset System will not be subject to an NFA assessment fee.
