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


	Year Ended December 31,
	2023		2024		2025
Net income	$	4,792	$	2,648	$	2,511
Add: convertible notes interest expense, net of tax	3		4		3
Net income - diluted	$	4,795	$	2,652	$	2,514
Weighted-average shares in computing net income per share attributable to Class A and Class B common stockholders:
Basic	637		632		613
Effect of dilutive securities	25		13		10
Diluted	662		645		623

Net income per share attributable to Class A and Class B common stockholders:
Basic	$	7.52	$	4.19	$	4.10
Diluted	$	7.24	$	4.11	$	4.03

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 income 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.

As of each December 31, 2023, 2024, and 2025, 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.
