13. | Earnings (Loss) Per Share
Earnings (loss) per share is computed using the two-class method. Basic earnings (loss) per share is computed using the weighted average number of shares of common stock outstanding for the period. Diluted earnings (loss) per share reflects the effect of the assumed exercise of stock options, the vesting of restricted stock units, and the conversion of convertible preferred stock only in the periods in which such effect would have been dilutive. Undistributed earnings are allocated to convertible preferred stock and shares of Class A common stock, Class B common stock, and Class C common stock based on the contractual participation rights of each as if earnings for the year had been distributed. Holders of convertible preferred stock are entitled to noncumulative annual dividends at a rate of 8% of the applicable original issue price when, as and if declared by the Company’s board of directors and prior to and in preference of payment of dividends on the Company’s common stock. Thereafter, dividends are distributed among holders of Class A common stock, Class B common stock, Class C common stock, and convertible preferred stock on a proportionate basis, based on the number of shares of common stock that would be held by each holder if all shares of convertible preferred stock were converted to Class B common stock at the then effective conversion rate. Holders of convertible preferred stock do not participate in losses and, accordingly, losses for the three and nine months ended September 30, 2021 and 2020 were allocated entirely to holders of Class A, Class B, and Class C common stock. For the three and nine months ended September 30, 2021 and 2020, net loss per share amounts were the same for Class A, Class B, and Class C common stock because the holders of each class are entitled to equal per share dividends. The table below presents the computation of basic and diluted loss per share (in thousands, except for per share amounts): ​

11. | Earnings (Loss) Per Share
Earnings (loss) per share is computed using the two-class method. Basic earnings (loss) per share is computed using the weighted average number of shares of common stock outstanding for the period. Diluted earnings (loss) per share reflects the effect of the assumed exercise of stock options, the vesting of restricted stock units, and the conversion of convertible preferred stock only in the periods in which such effect would have been dilutive. Undistributed earnings are allocated to convertible preferred stock and shares of Class A common stock and Class B common stock based on the contractual participation rights of each as if earnings for the year had been distributed. Holders of convertible preferred stock are entitled to noncumulative annual dividends at a rate of 8% of the applicable original issue price when, as and if declared by the Company’s board of directors and prior to and in preference of payment of dividends on the Company’s common stock. Thereafter, dividends are distributed among holders of Class A common stock, Class B common stock and convertible preferred stock on a proportionate basis, based on the number of shares of common stock that would be held by each holder if all shares of convertible preferred stock were converted to Class B common stock at the then effective conversion rate. During the year ended December 31, 2020 all undistributed earnings were allocated to holders of convertible preferred stock based on their contractual participation rights and, accordingly, no undistributed earnings were allocated to holders of Class A or Class B common stock. Holders of convertible preferred stock do not participate in losses and, accordingly, losses for the years ended December 31, 2019 and 2018 were allocated entirely to holders of Class A and Class B common stock. For the years ended December 31, 2020, 2019, and 2018 net income (loss) per share amounts were the same for Class A and Class B common stock because the holders of each class are entitled to equal per share dividends.
