Earnings Per Share [Abstract] |
Earnings Per Share | 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. Diluted earnings per share is calculated to give effect to stock options and restricted share awards. For the years ended December 31, 2016 and 2015, 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. Restricted shares of 726,936, 645,660, and 765,314 and options to purchase 206,854, 206,854, and 206,123 shares of common stock were outstanding at December 31, 2017, 2016, and 2015, respectively. The following table summarizes the dilutive effect of restricted shares and options to purchase common stock:
