EARNINGS PER SHARE

Basic earnings per share excludes dilution and is computed by dividing net income by the weighted-average number of ordinary shares outstanding during the applicable periods.

Diluted earnings per share reflects the potential dilution from stock options and share bonus awards. The potential dilution from stock options exercisable into ordinary share equivalents and share bonus awards was computed using the treasury stock method based on the average fair market value of the Company's ordinary shares for the period.

The following table reflects the basic weighted-average ordinary shares outstanding and diluted weighted-average ordinary share equivalents used to calculate basic and diluted income per share:

An immaterial amount of options to purchase ordinary shares during fiscal year 2018 were excluded from the computation of diluted earnings per share due to their anti-dilutive impact on the weighted average ordinary shares equivalents. Options to purchase ordinary shares of 0.5 million and 2.0 million during fiscal years 2017 and 2016, respectively, were excluded from the computation of diluted earnings per share.

Share bonus awards of less than 0.1 million during fiscal year 2018 and 2017, respectively, were excluded from the computation of diluted earnings per share due to their anti-dilutive impact on the weighted average ordinary shares equivalents. There were no anti-dilutive share bonus awards in fiscal year 2016.
