Earnings Per Share [Abstract] |
Earnings Per Common Share | 11. Earnings Per Common Share The Company calculates earnings per share using the two-class method. The two-class method allocates net income to each class of common stock and participating security according to common dividends declared and participation rights in undistributed earnings. Participating securities consist of nonvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents. A summary of the information used in the computation of earnings per common share follows.

Potential common shares consist of stock options, nonvested performance-based awards, and nonvested restricted share awards deferred under the Company’s nonqualified deferred compensation plan. These potential common shares do not enter into the calculation of diluted earnings per share if the impact would be antidilutive, i.e., increase earnings per share or reduce a loss per share. Weighted average antidilutive potential common shares totaled 43,794 and 37,680 for the three and nine months ended September 30, 2019, respectively. There were 14,904 and 18,257 antidilutive potential common shares excluded from the calculation of diluted earnings per share for the three and nine months ended September 30, 2018, respectively.
