Net Income per Share

3 Months Ended

Mar. 31, 2024

Basic and diluted net income per share are calculated by dividing net income by the number of basic and diluted weighted-average ordinary shares outstanding during the period. For the three months ended March 31, 2024 and 2023 the weighted-average ordinary shares outstanding used to calculate basic and diluted net income per share were as follows:


	For the three months ended
	March 31, 2024	March 31, 2023
Basic weighted-average ordinary shares outstanding	150,480	152,518
Dilutive effect of stock options	—	151
Dilutive effect of unvested restricted securities	441	655
Diluted weighted-average ordinary shares outstanding	150,921	153,324

Certain potential ordinary shares were excluded from our calculation of diluted weighted-average ordinary shares outstanding because either they would have had an anti-dilutive effect on net income per share or they related to equity awards that were contingently issuable for which the contingency had not been satisfied. These potential ordinary shares were as follows:


	For the three months ended
	March 31, 2024	March 31, 2023
Anti-dilutive shares excluded	1,763	381
Contingently issuable shares excluded	1,060	1,268
