Earnings Per Share [Text Block]	Note Q–Net Income Per Share of Common Stock Basic net income per share is based on the weighted average number of shares of common stock outstanding during the period. Diluted net income per share reflects: (a) the potential dilution assuming shares of common stock were issued upon the exercise of outstanding in-the-money options and the proceeds thereof were used to purchase treasury stock at the average market price during the period, and (b) the vesting of granted nonvested restricted stock awards for which the assumed proceeds upon grant are deemed to be the amount of compensation cost attributable to future services and are not yet recognized using the treasury stock method, to the extent dilutive. For the three- and nine-month periods ended September 30, 2011, options to purchase 19,000 and 169,000 shares, respectively, of the Company’s common stock have been excluded from the calculation because inclusion of such shares would be anti-dilutive as compared with options to purchase 177,100 shares of the Company’s common stock that have been excluded from the calculation for both the three and nine months ended September 30, 2010.
