NYMEX expanding Henry Hub contract Trade-at-settlement availability in May

Today, the CME issued a notice that effective May 19, for trading on May 20, it will be expanding the TAS trading on the NYMEX Henry Hub contract from the current availability of the spot month plus months two through seven to the spot month and months two through twelve. As always, TAS trades are not allowed on the last trading day of the spot month contract. 
As TAS trades are intended to reduce the execution risk of matching the day's settlement price, expansion of the range of month's available for TAS orders and execution could match risk management activities easier to manage.
