Schedule of Weighted-Average Potentially Dilutive Instruments

The following weighted-average potentially dilutive instruments are not included in the diluted net income (loss) per share calculations above because they would have had an antidilutive effect on the net income (loss) per share from continuing operations:


	Year Ended December 31,
	2021	2020	2019
Restricted stock units	500,763	1,887,322	1,652,002
Performance share units and other stock-based compensation awards	—	199,629	125,562
Convertible senior notes due 2022 (1)	—	2,314,815	2,314,815
Warrants	877,595	2,314,815	2,314,815
Capped call transactions	2,575,184	—	—
Total	3,953,542	6,716,581	6,407,194

(1)We apply the if-converted method in computing the effect of our convertible senior notes on diluted net income (loss) per share, whereby the numerator of our diluted net income (loss) per share computations is adjusted for interest expense, net of tax, and the denominator is adjusted for the number of shares into which the convertible senior notes could be converted. The effect is only included in the calculation of income (loss) per share for those instruments for which it would reduce income (loss) per share. See Note 8, Financing Arrangements, for additional information.
