Anti-dilutive shares and Potential Ordinary Shares That Were Not Otherwise Antidilutive excluded From Calculation of Diluted Weighted Average Shares Outstanding

Certain potential ordinary dilutive shares were excluded from the calculation of diluted weighted-average shares outstanding because they would have had an anti-dilutive effect on net income per share (see table below).
