Earnings Per Share

NOTE 2 – Earnings per Share

Earnings per share (“EPS”) is calculated by dividing net income attributable to common stockholders by the weighted-average number of shares of Common Stock outstanding during the period. Diluted EPS is calculated similarly but includes potential dilution from the exercise of stock options and stock awards, except when the effect would be anti-dilutive.  

The table below sets forth the reconciliation between net income and the weighted average shares outstanding used for calculating basic and diluted EPS:
