Beginning with the June 2015 contract month and pending regulatory approvals, we are introducing an important enhancement in the way that the majority of monthly NYMEX power contracts are processed at maturity. Please see Special Executive Report 7253RR at: http://www.cmegroup.com/tools-information/lookups/advisories/ser/files/SER-7253RR.pdf
Currently, the last day of trading for these monthly cash-settled contracts is the last business day of the contract month. With this change, the monthly contracts will terminate trading prior to the start of the contract month and positions in the monthly contracts will be transformed automatically into strips of positions in the corresponding daily contracts, thereby allowing individual daily positions to be managed separately.
For questions or further information, please contact CME Clearing Services (CCS) at 312-207-2525 or firstname.lastname@example.org.
