Amendment to Aggregation Ratio for PJM West Hub Real Time 50 MW Off-Peak Option Contract

Earlier today, Thursday, December 04, 2014, the New York Mercantile Exchange, Inc. (“NYMEX” or the “Exchange”) made a correction to the aggregation ratios (spot month, single month and all month) of the PJM West Hub Real Time 50 MW Off-Peak Option (N9P) contract as represented in the NYMEX Position Limit, Position Accountability and Reportable Level table.  This correction is administrative in nature as neither the contract size of N9P nor the contract size of PJM Off-Peak Calendar-Month LMP futures (JP), the contract into which N9P aggregates, has changed.  This amendment is non-substantive and is intended to reflect the proper aggregation ratios for the N9P contract.  Please note that this correction, noted below, does not impact the spot month limit or single month/all month accountability levels.  The correction has been inserted into the NYMEX Position Limit, Position Accountability and Reportable Level Table, located in the Interpretations & Special Notices Section of Chapter 5 of the NYMEX Rulebook.
