Earnings Per Common Share, Policy [Abstract]  
[Policy Text Block]
Basic earnings per common share ("EPS") is based upon the weighted-average number of common shares outstanding during the period. Diluted EPS reflects the potential dilution that would occur upon issuance of common shares for awards under stock-based compensation plans, exercise of warrants, or conversion of preferred stock, but only to the extent that they are considered dilutive.
