The following shows the weighted average number of shares used in computing earnings per common share and the effect on weighted average number of shares of potentially dilutive common stock. Potentially dilutive common stock had no effect on income available to common shareholders. Nonvested restricted shares are included in the computation of basic earnings per share as the holder is entitled to full shareholder benefits during the vesting period including voting rights and sharing in nonforfeitable dividends. The following table presents basic and diluted earnings per share for the three month periods ended March 31, 2018 and 2017.
