Earnings Per Share [Abstract] |
NET INCOME (LOSS) PER SHARE | NET INCOME (LOSS) PER SHARE Basic income (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share reflects the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted into common stock. For the three months ended March 31, 2014, 2,071,279 shares of common stock equivalents related to equity-based awards were not included in the diluted per share calculation due to the net loss incurred. For the three months ended March 31, 2013, 780,421 shares of common stock equivalents related to equity-based awards were not included in the diluted per share calculation as the shares would be antidilutive. The 3.25% Convertible Senior Notes were not included in the computation of diluted earnings per share for the three months ended March 31, 2014 and 2013 because there is no excess value upon conversion over the principal amount of the Notes.
