8. | Capital Stock
The Company’s authorized capital stock consists of 25 million shares of preferred stock, par value $0.001 per share, 500 million shares of Class A common stock, par value $0.001 per share, and 100 million shares of Class B common stock, par value $0.001 per share. As of December 31, 2020 and 2019, there were no preferred or Class B common shares outstanding. Each share of Class A common stock entitles the holder to one vote on matters submitted to a vote of the Company’s stockholders. Stock dividends of Class A common stock may be paid only to holders of Class A common stock. Class A common stock has no conversion rights. Weighted-average common shares outstanding The following is a reconciliation of the weighted-average common shares outstanding for purposes of computing basic and diluted net income per share (in thousands):
|  | Year Ended December 31, |
|  | 2020 |  |  | 2019 |  |  | 2018 |
Basic weighted-average common shares outstanding |  |  | 52,296 |  |  |  | 55,518 |  |  |  | 55,170 |
Effect of dilutive securities: |  |  |  |  |  |  |  |  |  |  |  |
Stock awards and options |  |  | 469 |  |  |  | 409 |  |  |  | 1,061 |
Convertible note |  |  | — |  |  |  | — |  |  |  | 245 |
Diluted weighted-average common shares outstanding |  |  | 52,765 |  |  |  | 55,927 |  |  |  | 56,476 |
For the years ended December 31, 2020, 2019 and 2018, other stock options totaling 0.4 million, 1.4 million and 0.9 million, respectively, were excluded from the calculation of diluted earnings per share because they were anti-dilutive. The convertible notes had a dilutive impact on EPS prior to their first quarter of 2018 conversion, when the average market price of the Company’s common stock for a given period exceeds the initial conversion price. Dividends Quarterly cash dividends for the years ended December 31, 2020 and 2019 totaled $78.4 million and $82.2 million or $0.375 per share in all quarters of 2020 and $0.37 for all quarters of 2019. The board of directors has declared a quarterly cash dividend of $0.38 per share of Class A common stock to be paid on March 10, 2021 to stockholders of record on February 26, 2021. Repurchases of common stock In 2015, the Company’s board of directors approved a stock repurchase plan authorizing the Company to repurchase up to $500.0 million of its outstanding shares of Class A common stock. In July 2018, the Company’s board of directors terminated the 2015 stock repurchase plan and approved a new repurchase plan with an initial authorization amount of $500 million. The repurchases are used primarily for strategic initiatives and to offset dilution from the Company’s equity incentive plans and, in 2018, from conversion of the convertible notes. During the years ended December 31, 2018, the Company repurchased 0.5 million shares of Class A common stock under the 2015 plan for an aggregate price of $40.6 million. During the years ended December 31, 2020, 2019 and 2018, the Company purchased 5.1 million, 14,000 and 0.4 million shares under the 2018 plan for $144.3 million, $0.8 million and $29.0 million, respectively. At December 31, 2020, $325.8 million was available for repurchases under the 2018 stock repurchase plan.
