Weighted Average Shares and Net Income Per Share [Abstract]  
Weighted Average Shares and Net Income Per Share
Note D — Weighted Average Shares and Net Income Per Share
     Weighted average basic common and common equivalent shares decreased from 11,957,000 for the quarter ended June 30, 2010 to 11,617,000 for the quarter ended June 30, 2011. Weighted average diluted common and common equivalent shares decreased from 12,187,000 for the quarter ended June 30, 2010 to 11,787,000 for the quarter ended June 30, 2011. The net decrease in both of these weighted share calculations is due to the repurchase of common stock as noted above, offset by an increase in shares outstanding due to the exercise of stock options under the Company’s employee stock option plan.
     Net income per common and common equivalent shares was computed by dividing net income by the weighted average number of common and common stock equivalents outstanding during the quarter. The calculations of the basic and diluted weighted shares for the three months ended June 30, 2010 and 2011, are as follows:
