Net Income (Loss) Per Share

Net Income (Loss) Per Share

Basic net income (loss) per share is computed using the weighted average number of shares of common stock ("Common Stock") outstanding, including restricted shares which, although they are legally outstanding and have voting rights, are subject to vesting and are treated as common stock equivalents in calculating basic income (loss) per share. Diluted net income (loss) per share is computed using the weighted average number of shares of Common Stock outstanding and dilutive potential shares of Common Stock from stock options outstanding during the period. Diluted shares outstanding include the dilutive effect of in-the-money options, which is calculated based on the average share price for each period using the treasury stock method.

Outstanding stock options to purchase 0.4 million shares were excluded from the computation of dilutive shares for the three months ended June 30,2014 and 2013 because of the net loss. In addition, for the three months ended June 30,2014, there were 8,141 potentially dilutive shares excluded from the calculation of diluted net loss per share because they were anti-dilutive, and there were no potentially dilutive shares to be excluded from the calculation of diluted net loss per share for the three months endedJune 30, 2013. Treasury shares are excluded from the number of shares outstanding.

Outstanding stock options to purchase 0.3 million shares were excluded from the computation of dilutive shares for the six months ended June 30,2014 because of the net loss. Outstanding stock options to purchase 0.4 million shares were excluded in the computation of dilutive shares for the six months ended June 30,2013 because of the net loss. In addition, for the six months ended June 30,2014, there were 7,206 potentially dilutive shares excluded from the calculation of diluted net loss per share because they were anti-dilutive, and there were no potentially dilutive shares to be excluded from the calculation of diluted net loss per share for the six months ended June 30,2013. Treasury shares are excluded from the number of shares outstanding.
