During the year ended December 31, 2017, the rights, including the liquidation and dividend rights, of the holders of Class A and Class B common stock were identical, except with respect to voting. As the liquidation and dividend rights were identical, the undistributed earnings were allocated on a proportionate basis and the resulting net loss per share attributable to common stockholders were, therefore, the same for both Class A and Class B common stock on an individual or combined basis.

On May 14, 2019, the Company completed its IPO, in which it issued and sold 180 million shares of its common stock at a price of $45.00 per share. On that date, all of the Company’s outstanding redeemable convertible preferred stock automatically converted into 905 million shares of common stock, and the holders of the 2021 Convertible Notes and the 2022 Convertible Notes elected to convert the outstanding notes into common stock, resulting in the issuance of 94 million shares of common stock. These shares were included in the Company’s issued and outstanding common stock starting on that date. Refer to Note 1 - Description of Business and Summary of Significant Accounting Policies for further information.

Since the Company was in a loss position for the years ended December 31, 2017 and 2019, basic net loss per share was the same as diluted net income per share for the periods presented. For the year ended December 31, 2018, all net income was allocated to noncumulative dividends on preferred stock, therefore basic net income per share was the same as diluted net income per share.

The following potentially dilutive outstanding securities were excluded from the computation of diluted net income (loss) per share because their effect would have been anti-dilutive for the periods presented, or issuance of such shares is contingent upon the satisfaction of certain conditions which were not satisfied by the end of the period (in thousands):
