On July 21, 2010, President Obama signed the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act” or “Dodd-Frank”) into law. Section 721(c) of Title VII of the Dodd-Frank Act made certain changes to the definition of the term “eligible contract participant” (“ECP”). Subsequently, as part of their efforts to implement Dodd-Frank, the Commodity Futures Trading Commission (the “CFTC”) and the Securities and Exchange Commission (the “SEC” and, together with the CFTC, the “Commissions”) proposed rules to further refine the definition of ECP under the Commodity Exchange Act (“CEA”) (the “Proposed Rules”). Unless the Commissions withdraw or revise the Proposed Rules before they become effective, the definitional change will negatively affect many commodity pools that engage in over-the-counter (“OTC”) foreign currency (“FX”) transactions. In a guest article, Steven M. Felsenthal, General Counsel and Chief Compliance Officer of Millburn Ridgefield Corporation, The Millburn Corporation and Millburn International, LLC, and Stephanie T. Green, a legal and compliance intern at The Millburn Corporation: (1) introduce the Proposed Rules as applied to commodity pools engaged in OTC FX transactions; (2) highlight the adverse result of the Proposed Rules; and (3) discuss revisions or alternatives to the Proposed Rules that could help to avoid such adverse results. While the focus of this article is the adverse results on commodity pools, the same adverse results would apply to any pooled investment vehicle that seeks to trade OTC FX forward contracts, including hedge funds that trade such instruments, because they would likely fall within the definition of commodity pool under Dodd-Frank.
