Earnings per Share

Net income is divided by the weighted average number of common shares outstanding during the year to calculate basic earnings per share. For the year ended December 31, 2020, no restricted shares or stock options were included in the computation of net income (loss) per share because to do so would be anti-dilutive. The following table summarizes the dilutive effect of RSUs and options to purchase common stock:
