(1)
An immaterial amount of options to purchase ordinary shares during fiscal years 2019 and 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 during fiscal year 2017 were excluded from the computation of diluted earnings per share.
(2)
Restricted share unit awards of 6.8 million during fiscal year 2019 were excluded from the computation of diluted earnings per share due to their anti-dilutive impact on the weighted average ordinary shares equivalents. Less than 0.1 million of anti-dilutive restricted share unit awards were excluded from the computation of diluted earnings per share during fiscal years 2018 and 2017, respectively.
