Slot Transaction

During June 2012, the Company transferred four permanent air carrier slots at Ronald Reagan National Airport to another airline ("buyer") for $9.1 million in cash, which the Company received in June. Due to FAA regulations, the buyer may not operate the slots until written confirmation of the slot transfer has been received from the FAA. In accordance with FAA's 80% “use or lose” requirements, the Company will continue to operate all four slots through September 6, 2012. Due to the restriction preventing operating use of the slots by buyer, the gain of $9.1 million was fully deferred as of June 30, 2012 and included within other current liabilities on the accompanying balance sheet. The Company expects to recognize a $9.1 million gain in the third quarter of 2012, the period in which the FAA operating restriction lapses and written confirmation of the slot transfer is expected to be received by the buyer from the FAA.
