Letter 13-48 grants relief from grants relief from the aggregation prohibition in § 43.6(h)(6) for certain commodity trading advisors (“CTAs”) and investment advisors (“IAs”) with respect to large notional off-facility swaps. The no-action letter provides that until October 1, 2013 at 11:59 pm EST, the Division will not recommend that the Commission take enforcement action against CTAs and IAs that aggregate orders for the purpose of executing large notional off-facility swaps, provided they meet specified conditions. The letter also grants relief from the aggregation prohibition in § 43.6(h)(6), for CTAs and IAs, subject to similar conditions as laid out in §43.6(h)(6), aggregating orders for swaps that are not listed on a swap execution facility (“SEF”) or a designated contract market (“DCM”). This letter has been amended from the original version that was issued on July 30, 2013.
