Net Income (Loss) Per Share of Common Stock

14. Net Income (Loss) Per Share of Common Stock

Basic net income (loss) per share is computed by dividing net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share is computed by dividing net income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding, including potential dilutive securities. In computing diluted net income (loss) per share, net income (loss) attributable to common shareholders is re-allocated to reflect the potential impact of dilutive securities, including stock options, unvested RSUs, unvested performance and market-based RSUs, ESPP withholdings and convertible debt instruments. For periods in which we have generated a net loss or there is no income attributable to common stockholders, we do not include dilutive securities in our calculation of diluted net income (loss) per share, as the impact of these awards is anti-dilutive.

The following tables set forth the computation of basic and diluted net income (loss) per share of common stock (in millions, except per share data):

	Three Months Ended March 31,
	2022			2021
Basic and Diluted:
Net income (loss) attributable to common stockholders	$	(24.5	)	$	(23.0	)
Weighted-average common shares outstanding		1,133.2			1,084.4
Net income (loss) per share attributable to common stockholders	$	(0.02	)	$	(0.02	)

The following weighted-average employee equity awards and convertible debt instruments were excluded from the calculation of diluted net income (loss) per share because their effect would have been anti-dilutive for the periods presented (in millions):

	Three Months Ended March 31,
	2022		2021
Stock options and employee stock purchase plan		23.4		29.0
RSUs (including performance and market- based awards)		64.4		64.8
Convertible senior notes⁽¹⁾		150.0		17.0
Total		237.8		110.8
