Settlement Method Financially Settled
Floating Price The Floating Price for each contract month will be equal to the NYMEX (Henry Hub) Natural Gas Futures contract settlement price for the corresponding contract month on the business day preceding the last trading day for that contract month.
Termination Of Trading Trading shall cease on the business day preceding the termination of trading for the corresponding contract month of the NYMEX (Henry Hub) Natural Gas Futures contract.
Trade At Marker Or Trade At Settlement Rules Trading at settlement is available for the front two months and is subject to the existing TAS rules of the underlying respective physical products. Trading in all TAS products will cease daily at 2:30 PM Eastern Time. The TAS products will trade off of a "Base Price" of 100 to create a differential (plus or minus) in points off settlement in the underlying cleared product on a 1 to 1 basis. A trade done at the Base Price of 100 will correspond to a "traditional" TAS trade which will clear exactly at the final settlement price of the day.
Settlement Procedures Delivery under the NYMEX Henry Hub Natural Gas Penultimate Swap contract shall be by cash settlement. Final settlement, following termination of trading for a contract month, will be based on the Floating Price. The final settlement price will be the Floating Price calculated for each contract month.
