The Company has two classes of common stock: Class A common stock and Class B common stock. Shares of Class A common stock and Class B common stock are identical, except with respect to voting and conversion rights. As of December 31, 2022 and September 30, 2023, 918 million and 948 million shares of Class A common stock were issued and outstanding, respectively. As of December 31, 2022 and September 30, 2023, 8 million shares of Class B common stock were issued and outstanding. As of December 31, 2022 and September 30, 2023, 3,500 million shares of Class A common stock and 8 million shares of Class B common stock were authorized.

Because the rights of the holders of Class A and Class B common stock, including liquidation and dividend rights, are identical except with respect to voting and conversion rights, undistributed earnings are allocated on a proportionate basis. As a result, net loss per share attributable to common stockholders is the same for Class A and Class B common stock, whether on an individual or combined basis.

Diluted net loss per share is computed by giving effect to all potential shares of common stock, to the extent dilutive, including shares underlying the 2029 Green Convertible Notes, stock options, unvested RSUs, shares underlying the Company’s ESPP, other stock-based awards, and stock warrants. Potential shares of common stock are excluded from the computation of diluted net loss per share if their effect would have been anti-dilutive for the periods presented or if the issuance of shares is contingent upon events that did not occur by the end of the period, in the case of the 2029 Green Convertible Notes, stock options with a market condition, and other stock-based awards. The following table presents the number of potential shares of common stock outstanding as of the end of each period that were excluded from the computation of diluted net loss per share for each period (in millions):
