Note 2. | Income Per Share
Basic income per share excludes dilution and is computed by dividing earnings available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted income per share reflects the dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in our earnings. There were no anti-dilutive shares for the three and nine months ended September 30, 2018. There were no outstanding stock options at September 30, 2018. Income per share is the same for both Class A and Class B shares. The following table sets forth for the periods indicated the calculation of net income per share included in the condensed consolidated statements of operations:
