On May 24th, the CFTC published a series of no-action letters previously issued by the Division of Swap Dealer and Intermediary Oversight which concern the registration of commodity pool operators. Letter No. 13-17, Letter No. 13-18, and Letter No. 13-19 each granted no-action relief to the general partners of commodity pools from registering as a CPO under Section 4m(1) of the Commodity Exchange Act, and allowing an affiliated CPO to serve as the CPO of the pools instead. Letter No. 13-20 provided similar relief to a managing member of a CPO.
