Earnings per Common Share

Basic earnings per common share are computed by dividing net income by the weighted average number of common shares outstanding for the period.  Diluted earnings per common share reflect the potential dilution that could occur if the Company's outstanding restricted stock units were vested. The dilutive effect was computed using the treasury stock method, which assumes all stock-based awards were exercised and the hypothetical proceeds from exercise were used by the Company to purchase common stock at the average market price during the period.  The incremental shares, to the extent they would have been dilutive, were included in the denominator of the diluted earnings per common share calculation.  The calculations of earnings per common share and diluted earnings per common share for the three and six months ended June 30, 2017 and 2016 are presented in the following table.
