Earnings Per Share [Abstract] |
Earnings Per Share | 11.EARNINGS PER SHARE Basic earnings per share was computed by dividing net income attributable to common shareholders by the weighted-average number of shares of Common Stock outstanding for each respective period. Diluted earnings per share was calculated by dividing net income attributable to common shareholders by the weighted-average number of shares of Common Stock outstanding adjusted for any dilutive Common Stock equivalents, including unvested restricted stock and shares issuable upon exercise of stock options as determined under the “If-Converted” method and also Common Stock warrants as determined under the “Treasury Stock” method. The following table sets forth basic and diluted net income per common share for the years ended December 31, 2018, 2017, and 2016 (in thousands, except per share data):
