Listed Contracts Monthly contracts listed for the current year and the next 3 calendar years.  Monthly contracts for a new calendar year will be added following the termination of trading in the December contract of the current year.
Settlement Method Financially Settled
Floating Price The Floating Price for each contract month is equal to the Henry Hub price minus the TTF price. The Floating Price for each contract month will be determined with reference to the   Volume Weighted Average price of the NYMEX Henry Hub Natural Gas Futures (NG) contract for the corresponding contract month during the period 16:00:00 to 16:29:59 London prevailing time and with reference to the midpoint between the bid and offer quotations for the TTF price assessment in US dollars per million British thermal units for the contract month, published by ICIS Heren in the European Spot Gas Market report on the Last Trading Day. For the avoidance of doubt, the calculated Floating Price will be rounded to three decimal places.
Termination Of Trading Trading terminates on the 3rd US business day immediately preceding the first calendar day of the Contract Month. If that day is not a London business day, trading terminates on the first preceding business day which is both a US and a London Business Day. On the last trading day, the trading terminates at 16:30 UK prevailing time (normally 11:30 ET).
