Equity [Abstract]

Shareholders' Equity

10. SHAREHOLDERS’ EQUITY

Common Stock Equivalents

The Company has potential common stock equivalents related to its outstanding stock options and restricted stock units (see Note 11) and the 1.875% Notes and the 4.0% Notes (see Note 8). These potential common stock equivalents were not included in diluted loss per share because the effect would have been anti-dilutive for each of the three months ended March 31, 2013 and 2012, respectively. Accordingly, basic and diluted loss per common share and the weighted average number of shares used in the computation are the same for each period presented.

Stock Repurchases

The Company’s Board of Directors authorized a stock repurchase program on April 27, 2011. This program authorizes the Company to purchase, from time to time, up to $300.0 million of the Company’s outstanding Class A common stock through open market repurchases in compliance with Rule 10b-18 of the Securities Exchange Act of 1934, as amended, and/or in privately negotiated transactions at management’s discretion based on market and business conditions, applicable legal requirements and other factors. This program became effective on April 28, 2011 and will continue until otherwise modified or terminated by the Company’s Board of Directors at any time in the Company’s sole discretion.

During the three months ended March 31, 2013 and 2012, the Company did not repurchase any shares in conjunction with the stock repurchase program. As of March 31, 2013, the Company had a remaining authorization to repurchase an additional $150.0 million of its common stock under its current $300.0 million stock repurchase program.
