Earnings Per Share [Abstract]

Earnings Per Share [Text Block]

EARNINGS PER SHARE

We compute basic earnings per common share by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common and potential common shares include additional shares in the weighted average share calculations associated with the incremental effect of dilutive employee stock options, restricted stock awards and contingently issuable shares, as determined using the treasury stock method. The

following table summarizes the calculation of weighted average common shares outstanding used in the computation of diluted earnings per share (in thousands):
