Formula. Airframe and Optional Features price adjustments (Airframe Price Adjustment) are used to allow prices to be stated in current year dollars at the signing of this Purchase Agreement and to adjust the amount to be paid by Customer at delivery for the effects of economic fluctuation. The Airframe Price Adjustment will be determined at the time of Aircraft delivery in accordance with the following formula: Pa = (P) (L + M) - P Where: Pa = Airframe Price Adjustment. (For Models 717-200, 737-600, 737-700, 737-800, 737-900, 777-200LR and 777-300ER the Airframe Price includes the Engine Price at its basic thrust level.) L = .65 x (ECI ECIb ) where ECIb is the base year index (as set forth in Table 1 of this Purchase Agreement) M = .35 x (CPI CPIb) where CPIb is the base year index (as set forth in Table 1 of this Purchase Agreement) P = Airframe Price plus Optional Features Price (as set forth in Table 1 of this Purchase Agreement). ECI is a value determined using the U.S. Department of Labor, Bureau of Labor Statistics Employment Cost Index Manufacturing – Total Compensation (BLS Series ID ECU12402I), calculated by establishing a three-month arithmetic average value (expressed as a decimal and rounded to the nearest tenth) using the values for the 11th, 12th and 13th months prior to the month of scheduled delivery of the applicable Aircraft. As the Employment Cost Index values are only released on a quarterly basis, the value released for the first quarter will be used for the months of January, February and March; the value released for the second quarter will be used for the months of April, May and June; the value released for the third quarter will be used for the months of July, August and September; the value released for the fourth quarter will be used for the months of October, November and December. CPI is a value determined using the U.S. Department of Labor, Bureau of Labor Statistics Consumer Price Index (BLS Series ID CUUR0000SA0), calculated as a 3-month arithmetic average of the released monthly values (expressed as a decimal and rounded to the nearest tenth) using the values for the 11th, 12th and 13th months prior to the month of scheduled delivery of the applicable Aircraft. As an example, for an Aircraft scheduled to be delivered in the month of July, the months June, July and August of the preceding year will be utilized in determining the value of ECI and CPI.
