Under the current 787-9 purchase agreement and supplemental agreement, except as described below, American will not be obligated to purchase a 787-9 aircraft unless it gives Boeing notice confirming its election to do so at least 18 months prior to the scheduled delivery date for that aircraft. If American does not give that notice with respect to an aircraft, the aircraft will no longer be subject to the 787-9 purchase agreement. These confirmation rights may be exercised until a specified date (May 1, 2014 under the current agreement) provided that those rights will terminate earlier if American reaches a collective bargaining agreement with its pilot union that includes provisions enabling American to utilize the 787-9 to American's satisfaction in the operations desired by American, or if American confirms its election to purchase any of the initial 42 787-9 aircraft. While there can be no assurances, American expects that it will have reached an agreement as described above with its pilots union prior to the first notification date. In either of those events, American would become obligated to purchase all of the initial 42 aircraft then subject to the purchase agreement. If neither of those events occurs prior to the specified date(May 1, 2014 under the current agreement) then on that date American may elect to purchase all of the initial 42 aircraft then subject to the purchase agreement, and if it does not elect to do so, the purchase agreement will terminate in its entirety.
