The following table sets forth the computation of basic and diluted net loss per share attributable to common stockholders for the years indicated (in millions, except per share amounts):


	Year Ended December 31,
	2021		2022		2023
Net income (loss)	$	(352)	$	1,893	$	4,792
Add: convertible notes interest expense, net of tax	—		4		3
Net income (loss) - diluted	$	(352)	$	1,897	$	4,795
Weighted-average shares in computing net income (loss) per share attributable to Class A and Class B common stockholders:
Basic	616		637		637
Effect of dilutive securities	—		43		25
Diluted	616		680		662

Net income (loss) per share attributable to Class A and Class B common stockholders:
Basic	$	(0.57)	$	2.97	$	7.52
Diluted	$	(0.57)	$	2.79	$	7.24

The rights, including the liquidation and dividend rights, of the holders of Class A and Class B common stock are identical, except with respect to voting and conversion. Each share of Class A common stock is entitled to one vote per share and each share of Class B common stock is entitled to 20 votes per share. Each share of Class B common stock is convertible into a share of Class A common stock voluntarily at any time by the holder, and automatically upon certain events. The Class A common stock has no conversion rights. As the liquidation and dividend rights are identical for Class A and Class B common stock, the undistributed earnings are allocated on a proportional basis and the resulting net loss per share attributable to common stockholders will, therefore, be the same for both Class A and Class B common stock on an individual or combined basis.

There were no preferred dividends declared or accumulated for the years ended December 31, 2021, 2022 and 2023. As of each December 31, 2021, 2022 and 2023, RSUs to be settled in 9.6 million shares of Class A common stock were excluded from the table below because they are subject to market conditions that were not achieved as of such date. As of December 31, 2021, 0.5 million shares of RSAs were excluded from the table below because they are subject to performance conditions that were not achieved as of such date. As of December 31, 2022 and 2023, 0.3 million shares of RSAs were excluded from the table below because they are subject to performance conditions that were not achieved as of such date.

(1)Holders of the 2026 Notes who convert their 2026 Notes in connection with certain corporate events that constitute a make-whole fundamental change are entitled to an increase in the conversion rate. The 11.1 million shares represent the maximum number of shares that could have been issued upon conversion after considering the make-whole fundamental change adjustment on an unweighted basis.
