Earnings Per Share [Abstract] |
Earnings Per Share | Note 2: Earnings Per Share Earnings per common share (EPS) is computed using the two-class method. Basic earnings per common share is computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding during the applicable period, excluding participating securities. Participating securities include non-vested restricted stock awards. Non-vested restricted stock awards are considered participating securities to the extent the holders of these securities receive non-forfeitable dividends at the same rate as holders of common shares. Diluted earnings per common share is computed using the weighted-average number of shares determined for the basic earnings per common share plus the convertible impact of preferred shares and the dilutive effect of stock compensation using the treasury stock method. EPS for the years ended December 31, 2017, 2016 and 2015 is computed as follows:
