Earnings Per Share [Abstract]

Earnings Per Share [Note Text Block]

Basic earnings per share is computed by dividing earnings by the weighted average number of common shares outstanding. Diluted earnings per share is computed assuming that all potentially dilutive securities were converted into common shares. There are no adjustments required to be made to net income for purposes of computing basic and diluted earnings per share.
