The actual average values ; then, in the event the Engine Price escalation provisions are calculated as a three (3) month arithmetic average made non-enforceable or otherwise rendered null and void by any agency of the released monthly United States Government, GE agrees to meet jointly with Boeing and Customer (to the extent such parties may lawfully do so) to adjust equitably the Aircraft Basic Price of any affected Aircraft to reflect an allowance for increase or decrease in labor compensation and material costs occurring since February of the base price year which is consistent with the application provisions of this Supplemental Exhibit EE1. (e) If prior to delivery of an Aircraft, the U.S. Department of Labor, Bureau of Labor Statistics substantially revises the methodology used for the determination of the values to be used to determine the L and ICI values (expressed as in contrast to benchmark adjustments or other corrections of previously released values), Customer, Boeing and GE will, prior to delivery of such Aircraft, select a decimal and rounded substitute for such values from data published by the U.S. Department of Labor, Bureau of Labor Statistics or other similar data reported by non-governmental United States organizations, such substitute to lead in application to the nearest tenthsame adjustment result insofar as possible, as would have been achieved by continuing the use of the original values as they may have fluctuated during the applicable time period. Appropriate revisions of the formula will be made as required to reflect any substitute values. However, if within twenty-four (24) using months from delivery of the Aircraft, the U.S. Department of Labor, Bureau of Labor Statistics FED-PA-03712-EE1 December 12, 2011 should resume releasing values for the 11th, 12th and 13th months prior needed to determine the Engine Price base year.
