ACQUISITIONS AND DISPOSITIONS	Note 2 ¾ ACQUISITIONS AND DISPOSITIONS Heliservicio and RLR Prior to January 2011, we had a 24% interest in Heliservicio and a 99% interest in Rotorwing Leasing Resources, L.L.C. (“RLR”) for our operations in Mexico. On January 14, 2011, we entered into an Equity Interest Purchase and Sale 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 and the owner of the other 1% of 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 an 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 fiscal year 2012. We acquired the remaining 1% interest in RLR for $0.3 million. We continue to lease aircraft from RLR and other consolidated subsidiaries to Heliservicio under revised lease agreements.
