Earnings Per Share [Abstract] |
Earnings Per Share, Policy [Policy Text Block] | Basic earnings per common share is computed based on the weighted-average number of common shares outstanding during the reporting period. Diluted earnings per common share is computed based on the combination of dilutive common share equivalents, comprised of shares issuable under the Company's stock-based compensation plans and the weighted-average number of common shares outstanding during the reporting period. Dilutive common share equivalents include the dilutive effect of in-the-money options to purchase shares, which is calculated based on the average share price for each period using the treasury stock method.
