Earnings Per Common Share
10.   Earnings Per Common Share
   
Basic earnings per common share are computed based upon the weighted average number of common shares outstanding during the period. Diluted earnings per common share are based upon the increased number of common shares that would be outstanding assuming the exercise of dilutive common share options and the consideration of restricted stock awards. The following table details the computation of earnings per common share, basic and diluted:
