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-R and CPI 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.

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-R and CPI [*CTR] 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 [CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO A REQUEST FOR CONFIDENTIAL TREATMENT*CTR] 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-R and CPI [*CTR] values as defined above, such re-based values will be incorporated in the Airframe Price Adjustment calculation. 2.3 In the event escalation provisions are made non-enforceable or otherwise rendered void by any agency of the United States Government, the parties agree, to the extent they may lawfully do so, to equitably adjust the Aircraft Price of any affected Aircraft to reflect an allowance for increases or decreases consistent with the applicable provisions of paragraph 1 of this Supplemental Exhibit AE1 in labor compensation and material costs occurring since August of the year prior to the price base year shown in the Purchase Agreement. 2.4 If within [CONFIDENTIAL MATERIAL OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO *CTR] months of Aircraft delivery, the published index values are revised due to an acknowledged error by the Bureau of Labor Statistics, the Airframe Price Adjustment will be re-calculated using the revised index values (this does not include those values noted as preliminary by the Bureau of Labor Statistics). A REQUEST FOR CONFIDENTIAL TREATMENT]credit memorandum or supplemental invoice will be issued for the Airframe Price Adjustment difference. Interest charges will not apply for the period of original invoice to issuance of credit memorandum or supplemental invoice. Note: (i) The values released by the Bureau of Labor Statistics and available to Boeing [*CTR] prior to the first day of the scheduled delivery month of an Aircraft will be used to determine the [*CTR] values for the applicable months (including those noted as preliminary by the Bureau of Labor Statistics) to calculate the Airframe Price Adjustment for the Aircraft invoice at the time of delivery. The values will be considered final and no Airframe Price Adjustments will be made after Aircraft delivery for any subsequent changes in published index values, subject always to paragraph 2.4 above. (ii) The maximum number of digits to the right of the decimal after rounding utilized in any part of the Airframe Price Adjustment equation will be 4, where rounding of the fourth digit will be increased to the next highest digit when the 5th digit is equal to five (5) or greater.
