Share Repurchase Program [Abstract]
Share Repurchase Program	3.Share Repurchase Program In August 2014, the Company’s Board of Directors extended the Company’s share repurchase program, authorizing the Company to purchase up to $105 million of its outstanding shares of common stock to be repurchased through August 31, 2015. Share repurchases may be made from time to time in the open market or otherwise, including through an accelerated share repurchase program, under terms of a Rule 10b5-1 plan, in privately negotiated transactions or in round lot or block transactions. The share repurchase program may be extended, modified, suspended or discontinued at any time. In October 2014, the Company entered into an accelerated share repurchase (“ASR”) agreement with a financial institution to purchase $15 million of the Company’s common stock. In exchange for a $15 million up-front payment, the financial institution delivered approximately 0.6 million shares. During January 2015, the ASR purchase period concluded, and the Company elected to settle the agreement in cash rather than shares. Accordingly, the Company paid $0.1 million, and no additional shares were delivered, resulting in an average price per share of $26.32. In February 2015, the Company entered into additional ASR agreements with a financial institution to purchase $75 million of the Company’s common stock. These ASR transactions were funded with available cash on hand and funds from borrowing on the Company’s Series 2011-1 Senior Secured Variable Funding Notes, Class A-1 (the "2011 Variable Funding Notes"). In exchange for a $75 million up-front payment, the financial institution delivered approximately 2.1 million shares. The actual number of shares repurchased, and therefore the average price paid per share, will be determined upon completion of the programs, which is expected to occur no later than August 2015. The Company reflected the ASR transactions as a repurchase of common stock for purposes of calculating earnings per share and as a forward contract indexed to its own common stock. The forward contract met all of the applicable criteria for equity classification. Including shares repurchased through the ASR transactions described above, during the first six months of fiscal year 2015, approximately 2.9 million shares were repurchased for a total cost of $95.3 million. The total remaining amount authorized under the share repurchase program, as of February 28, 2015, was $9.7 million.
