Computation of Net Income (Loss) Per Share

Basic earnings per share (“EPS”) is computed by dividing net income (loss) by the weighted average number of shares of Common Stock outstanding for the period. Diluted EPS reflects the potential dilution of securities that could share in earnings. When the impact of common share equivalents is anti-dilutive, they are excluded from the calculation.

The following table sets forth the calculation of basic and diluted income (loss) per share for the periods indicated (in thousands, except per share data):

For the three months ended March 31, 2019, certain common stock equivalents were not included in the computation of diluted income (loss) per share because the effect would have been anti-dilutive. These common share equivalents totaled approximately 0.2 million. For the three months ended March 31, 2018, approximately 1.3 million common stock equivalents were completely excluded from the calculation of diluted income (loss) per share because they were anti-dilutive.
