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 June 30, 2014, 2,147,989 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 June 30, 2013, 1,202,100 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.
For the six months ended June 30, 2014, 2,147,390 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 six months ended June 30, 2013, 1,202,100 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 net income (loss) per share for the three and six months ended June 30, 2014 and 2013 because there is no excess value upon conversion over the principal amount of the Notes.
