Earnings per Share
 
Basic earnings per common share is computed by dividing net income available to common shareholders by the weighted average number of shares of common stock outstanding during the period.

For the three months ended March 31, 2019, options to purchase 487,000 shares were antidilutive and accordingly were excluded in the computation of diluted earnings per share, compared to 274,000 shares for the three months ended March 31, 2018.
