In December 2014, the Company filed a request for an advance consent for a change in tax accounting method for its lease payments on certain leased aircraft effective for its 2014 tax year. On July 13, 2015, the Company received approval from the Internal Revenue Service. As of September 30, 2015, the impact of this tax accounting method change reduces income tax payable in the amount of $35.1 million, with a corresponding increase in long-term deferred tax liability.
