NOTE 12:        EARNINGS PER SHARE

As per the Accounting Standards Classification section 260, basic earnings per share are computed by dividing net earnings available to common shareholders (the numerator) by the weighted average number of common shares (the denominator) for the period presented. The computation of diluted earnings per share is similar to basic earnings per share, except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potentially dilutive common shares had been issued.

Stock options to purchase 258,930 shares of common stock were outstanding and 208,930 were exercisable during the three and six months ended June 30, 2012. Stock options to purchase 403,550 shares were outstanding and 334,550 were exercisable during the three and six months ended June 30, 2011. At June 30, 2012 and June 30, 2011, all outstanding options were included in the diluted earnings per share calculation because the average market price was higher than the exercise price.

The dilutive potential common shares on warrants and options is calculated in accordance with the treasury stock method, which assumes that proceeds from the exercise of all warrants and options are used to repurchase common stock at market value. The amount of shares remaining after the proceeds are exhausted represents the potential dilutive effect of the securities.
