In the fourth quarter of 2012, the Company recorded a net frequent flyer pre-tax adjustment of $7.3 million to correct an error in the Company's accounting for its sale of mileage credits to companies participating in the Company's frequent flyer program that are deferred and recognized as passenger revenue. The correction resulted in a change in the deferral period from 19 to 22 months. The error primarily relates to prior periods and the impact of the error was not material to any prior period or the 2012 fiscal year.

In the second quarter of 2011, the Company entered into a purchase agreement with the lessor for the purchase of fifteen Boeing 717-200 aircraft. The excess of the purchase price paid over the fair value of the aircraft, which was $70.0 million, was recognized as a cost of terminating the leases and recorded on the Consolidated Statements of Operations.

The sum of the quarterly earnings per share amounts does not equal the annual amount reported since per share amounts are computed independently for each quarter and for the full year based on respective weighted-average common shares outstanding and other dilutive potential common shares.
