Note P - Net Income Per Share of Common Stock | 6 Months Ended
--- | ---
Jun. 30, 2011
Earnings Per Share [Text Block] | Note P – 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, which does not include unvested restricted stock subject to forfeiture. 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 shares of the Company’s common stock at the average market price during the period, and b) 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 both the three- and six-month periods ended June 30, 2011, 150,000 options to purchase shares 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 236,000 shares of the Company’s common stock that have been excluded from the calculation for the three and six months ended June 30, 2010.
