The CFTC extended the recently reopened comment period for two rulemakings related to position limits and the aggregation of positions for purposes of position limits.  The comment period was initially reopened in May 2014 in order to address issues at a June 19, 2014 roundtable concerning the two rulemakings.  The CFTC is requesting additional comments concerning issues associated with the hedging of a physical commodity by a commercial enterprise, the setting of spot-month limits and a conditional spot-month limit exemption, aggregation exemptions for certain ownership interests of greater than 50 percent in an owned entity and aggregation based on similar trading strategies.  Comments are due by August 4, 2014.
