Earnings Per Share [Abstract] |
Net Income (Loss) Per Share | Net Income (Loss) Per Share Basic earnings per share, or EPS, is calculated by dividing net income by the weighted-average number of common shares outstanding for the period, without consideration for common stock equivalents. Diluted EPS is computed by dividing net income by the weighted-average number of common shares outstanding for the period and the weighted-average number of dilutive common stock equivalents outstanding for the period determined using the treasury-stock method. For purposes of this calculation, common stock options, restricted stock units and restricted stock awards are considered to be common stock equivalents and are only included in the calculation of diluted EPS when their effect is dilutive. In periods in which the Company has a net loss, dilutive common stock equivalents are excluded from the calculation of diluted EPS. The table below presents the computation of basic and diluted EPS:

The Company excluded 3.6 million and 1.3 million common stock equivalents for outstanding stock-based awards for the three months ended June 30, 2018 and 2017, respectively, from the calculation of diluted net income (loss) per share due to their anti-dilutive nature. The Company excluded 3.7 million and 0.9 million common stock equivalents for outstanding stock-based awards for the six months ended June 30, 2018 and 2017, respectively, from the calculation of diluted net income (loss) per share due to their anti-dilutive nature.
