Weighted Average Common Shares [Abstract]

16. Weighted Average Common Shares

Basic income per common share is computed by dividing income by the weighted average number of common shares outstanding during the period. Diluted income per common share is computed similarly to basic income per common share except that weighted average common shares are increased to include the potential issuance of dilutive common shares.
