Roll

Roll means an adjustment to the NYMEX price that is calculated as follows: Roll = .6667 (P0P1) + .3333 (P0P2), where: P0 = the average of the daily NYMEX settlement prices for deliveries during the prompt month that is the same as the month of production, as published for each day during the trading month for which the month of production is the prompt month; P1 = the average of the daily NYMEX settlement prices for deliveries during the month following the month of production, published for each day during the trading month for which the month of production is the prompt month; and P2 = the average of the daily NYMEX settlement prices for deliveries during the second month following the month of production, as published for each day during the trading month for which the month of production is the prompt month. Calculate the average of the daily NYMEX settlement prices using only the days on which such prices are published (excluding weekends and holidays). ONRR reserves the option of terminating the use of the roll when ONRR believes that the roll is no longer a common industry practice. ONRR also retains the option to redefine how to calculate the roll to comport with changes in industry practice. To terminate or otherwise redefine how to calculate the roll, ONRR will explain its rationale for terminating or redefining how to calculate the roll by publishing a notice in the Federal Register, to provide an opportunity for comment.
