Notes to Financial Statements [Abstract]
Earnings Per Share, Policy Basic and Diluted	Basic earnings per share is calculated by dividing net income associated with common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share assumes the issuance of additional shares of common stock by the Company upon exercise of all outstanding stock options and contingently issuable securities if the effect is dilutive, in accordance with the treasury stock method discussed in ASC 260-10, Earnings Per Share. The determination and reporting of earnings per share requires the inclusion of time and performance-based restricted stock as participating securities, since they have the right to share in dividends, if declared, equally with common shareholders. During periods of net income, participating securities are allocated a proportional share of net income determined by dividing total weighted average participating securities by the sum of total weighted average common shares and participating securities (“the two-class method”). During periods of net income, participating securities have the effect of diluting both basic and diluted earnings per share. During periods of net loss, no effect is given to participating securities, since they do not share in the losses of the Company.
