Earnings Per Share [Abstract]  
Net Income Per Share
Note 2:  Net Income Per Share
 
In accordance with the provisions of ASC Topic 260 (“Earnings Per Share”) basic net income per share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period.  Diluted net income per common share includes the dilutive effect of potential restricted stock and stock options exercised and the effects of the potential conversion of preferred shares, calculated using the treasury stock method.  Outstanding stock options, restricted stock, and convertible preferred shares issued by the Company represent the only dilutive effect reflected in diluted weighted average shares outstanding.  The following is a reconciliation of the numerators and denominators of the basic and diluted net income per share computations for the periods presented (in thousands, except for per share amounts):

At December 31, 2011 and 2010, all common restricted stock and stock options were included in the diluted net income per common share computation as their exercise prices were less than the average market price of the common shares for the period.
