ACQUISITIONS AND DISPOSITIONS	Note 2 ¾ ACQUISITION AND DISPOSITION On January 14, 2011, we entered into an Equity Interest Purchase and Sale Agreement (the “Equity Agreement”) with Controladora De Servicios Aeronauticos, S.A. de C.V. (“CICSA”) and Rotorwing Financial Services, Inc. (“RFS”), the owner of the other 76% of Heliservicio Campeche S.A. de C.V. (“Heliservicio”) and the owner of the other 1% of Rotorwing Leasing Resources, L.L.C. (“RLR”), respectively. Through this agreement, we and our partners agreed that CICSA would purchase the remaining 24% interest in Heliservicio. Additionally, concurrent with the sale of our interest in Heliservicio, we would execute our option to purchase the 1% interest in RLR owned by RFS. This transaction closed on July 15, 2011 resulting in us having no ownership interest in Heliservicio and full ownership of RLR. Our ownership interest in Heliservicio transferred to CICSA for no proceeds; however, as we had impaired our investment in Heliservicio as of March 31, 2011 we recognized no gain or loss on this transaction during the three months ended September 30, 2011. We acquired the remaining 1% interest in RLR for $0.3 million. We will continue to lease aircraft from RLR and other consolidated subsidiaries to Heliservicio under revised lease agreements.
