Note 10. Earnings Per Common Share

Basic earnings per common share is computed by dividing earnings available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per common share reflects the potential dilution of securities that could share in the Company's earnings, including exercise of outstanding stock options and non-vested restricted stock. As discussed in Note 8, the conditions for conversion related to the Company's Convertible Debentures have never been met. Accordingly, there was no impact on diluted earnings per share attributable to assumed conversion. When the exercise of stock options or the inclusion of awards would be anti-dilutive, they are excluded from the earnings per common share calculation. For the three and six months ended June 30, 2011 and 2010, there were no excluded shares underlying anti-dilutive stock options and awards.

A reconciliation of the numerators and the denominators of the basic and diluted earnings per common share computations is as follows:
