Earnings Per Share [Abstract] |
Earnings Per Common Share | NOTE 3. Earnings Per Common Share Basic earnings per share represents income available to common shareholders divided by the weighted average number of common shares outstanding during the period. Nonvested restricted shares are included in the weighted average number of common shares used to compute basic earnings per share because of dividend participation and voting rights. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. The number of potential common shares is determined using the treasury method. The following table shows the weighted average number of shares used in computing earnings per share for the three months ended March 31, 2018 and 2017. During 2018 and 2017, there were no potentially dilutive securities outstanding.
