Note 13 - Income (Loss) per Common Share | 12 Months Ended
--- | ---
Dec. 31, 2012
Earnings Per Share [Text Block] | Note 13: Income per Common Share We calculate basic earnings per share using, as the denominator, the weighted average number of common shares outstanding during the period. Diluted earnings per share uses, as its denominator, the weighted average number of common shares outstanding during the period plus the effect of potential dilutive common shares during the period using the treasury stock method for options, warrants, and restricted stock units, and if-converted method for convertible preferred shares. Potential dilutive common shares include outstanding stock options, restricted stock awards, stock units, warrants and convertible preferred stock for periods in which we have reported net income. For periods in which we reported net losses, potential dilutive common shares are excluded, as their conversion and exercise would not reduce earnings per share. Under the if-converted method, preferred shares would not dilute earnings per share in any of the periods presented. A total of 157,814 shares of preferred stock were outstanding at December 31, 2012. The following table represents net income per common share – basic and diluted (in thousands, except earnings per share):
