Computation of Earnings Per Share

9 Months Ended

Sep. 30, 2019

Basic earnings per share (“EPS”) is computed by dividing net income by the weighted average number of shares of Common Stock outstanding during 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 table below sets forth the calculation of basic and diluted income per share for the periods indicated (in thousands, except per share data).

Certain common stock equivalents were not included in the computation of diluted income per share because the effect would have been anti-dilutive. These common share equivalents totaled less than 0.2 million for each of the three and nine months ended September 30, 2018. For the three and nine months ended September 30, 2019, approximately 0.3 million and 0.2 million, respectively, of common stock equivalents were excluded from the calculation of diluted income per share because they were anti-dilutive.
