Earnings Per Share [Abstract]  
Earnings per Share
Note 6.  Earnings per Share
Basic earnings per share is computed by dividing net income by the weighted average number of shares outstanding during the period.  Diluted earnings per share is computed using the weighted average number of common shares outstanding during the period, including the effect of dilutive potential common shares attributable to outstanding stock options.

The Company did not include an average of 208 thousand potential common shares attributable to outstanding stock options in the diluted earnings per share calculation for the first half of 2011 because they were antidilutive.
