Net Income Per Share
NOTE 4. NET INCOME PER SHARE
Net income per basic share is computed based on the weighted-average number of common shares issued and outstanding during each period. Net income per diluted share amounts assume conversion, exercise or issuance of all potential common stock instruments (stock options and warrants). Stock options and warrants totaling 5,000 for the quarters ended June 30, 2012 and 2011 were not included in the computation of diluted earnings per share because the exercise prices of the options and warrants were greater than the market price of the common stock. The following table reflects the components of common shares outstanding:
