Settlement Method Deliverable
Floating Price The Floating Price for each contract month will be equal to the arithmetic average of all Electric Reliability Council of Texas (ERCOT) North 345 kV Hub real-time settlement point off-peak prices provided for the contract month. For settlement of this contract, the prices provided by ERCOT will be considered final on the payment date stated in Rule 281.09 and will not be subject to any further adjustment.
Termination Of Trading Trading terminates on the last business day of the month before the contract month. At that time, a position in ERCOT North 345 kV Hub 5 MW Off-Peak Futures (I6) converts to a strip of ERCOT North 345 kV Hub 5 MW Off-Peak Calendar-Day Futures (I8)  in the originally specified contract month. For example, in a 28-day month with 352 off-peak hours and no transition in or out of Daylight Savings Time, a position of 352 ERCOT North 345 kV Hub 5 MW Off-Peak Futures (I6) converts at the termination of trading to a position of eight (8) ERCOT North 345 kV Hub 5 MW Off-Peak Calendar-Day Futures (I8) per weekday in the originally specified contract month and twenty-four (24) per weekend day (or holiday)  in the originally specified contract month.
Days Or Hours Off-Peak shall mean Monday through Friday Hour Ending (HE) 0100-0600 and 2300 and 2400 Central Prevailing Time (CPT) and Saturday through Sunday HE 0100-2400 CPT including North American Electric Reliability Corporation holidays.
