(a) Intangible assets primarily consist of acquired leasehold rights to certain airport owned gates at Chicago’s Midway International Airport, take-off and landing slots (a “slot” is the right of an air carrier, pursuant to regulations of the Federal Aviation Administration (“FAA”), to operate a takeoff or landing at a specific time at certain airports) at certain domestic slot-controlled airports, and certain intangible assets recognized from the AirTran acquisition. The increase in Intangible assets during first quarter 2014 was primarily due to the acquisition of additional slots at Washington Reagan National Airport, divested in connection with the merger between AMR Corporation, the parent company of American Airlines, Inc., and US Airways Group, Inc. The slots acquired are not subject to amortization due to the ability to renew the slots on an unlimited basis, the expectation that the slots will contribute positive cash flows for an indefinite period of time, and the Company's recent significant growth in certain slot-controlled airports. The purchase price paid for these slots was included as a component of Capital expenditures in the accompanying unaudited Condensed Consolidated Statement of Cash Flows.
