Common use of Values to be Utilized in the Event of Unavailability Clause in Contracts

Values to be Utilized in the Event of Unavailability. 2.1 If the Bureau of Labor Statistics substantially revises the methodology used for the determination of the values to be used to determine the ECI and ICI values (in contrast to benchmark adjustments or other corrections of previously released values), or for any reason has not released values needed to determine the applicable Airframe Price Adjustment, the parties will, prior to the delivery of any such Aircraft, select a substitute from other Bureau of Labor Statistics data or similar data reported by non-governmental organizations. Such substitute will result in the same adjustment, insofar as possible, as would have been calculated utilizing the original values adjusted for fluctuation during the applicable time period. However, if within 24 months after delivery of the Aircraft, the Bureau of Labor Statistics should resume releasing values for the months needed to determine the Airframe Price Adjustment, such values will be used to determine any increase or decrease in the Airframe Price Adjustment for the Aircraft from that determined at the time of delivery of the Aircraft. 2.2 Notwithstanding Article 2.1 above, if prior to the scheduled delivery month of an Aircraft the Bureau of Labor Statistics changes the base year for determination of the ECI and ICI values as defined above, such re-based values will be incorporated in the Airframe Price Adjustment calculation. 2.3 [CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT]
