Net (Loss) Income Per Share

6 Months Ended

Jun. 30, 2021

Basic net (loss) income per share is computed by dividing net (loss) income by the weighted average number of common shares outstanding for the period. Diluted net (loss) income per share is computed using the weighted average number of common shares outstanding and, when dilutive, common share equivalents from outstanding stock options and restricted stock units (using the treasury-stock method), and potential common shares from the Company’s convertible notes (using the if-converted method). The weighted-average number of common shares used in the computation of basic and diluted net income per share were as follows:


	Three Months Ended June 30,		Six Months Ended June 30,
(in thousands)	2021	2020	2021	2020
Weighted average number of common shares outstanding, basic	66,696	64,371	66,406	63,627
Stock options	—	1,087	—	1,130
Restricted stock units	—	121	—	213
Weighted average number of common shares outstanding, diluted	66,696	65,579	66,406	64,970

The number of common share equivalents excluded from the computation of diluted net (loss) income per share because either the effect would have been anti-dilutive, or the performance criteria related to the units had not yet been met, were as follows:
