Basic earnings per common share is computed using net income and the weighted average number of common shares outstanding during the period.  Diluted earnings per common share are computed using net income and the weighted average number of common shares outstanding, assuming dilution.  Weighted average common shares outstanding, assuming dilution, include potentially dilutive common shares outstanding during the period. Potentially dilutive common shares include the assumed exercise of warrants using the treasury stock method.
