Note 4- Earnings (loss) Per Share

Earnings (loss) per share is calculated in accordance with ASC Topic 260 “Earnings Per Share,” which provides for the calculation of “basic” and “diluted” earnings (loss) per share. Basic earnings (loss) per share includes no dilution and is computed by dividing net earnings by the weighted average number of common shares outstanding for the period.  Diluted earnings (loss) per share reflect, in periods in which they have a dilutive effect, the effect of common shares issuable upon exercise of stock options. The diluted share base excludes incremental shares of 1,022 and 1,458 related to stock options for the three and six month periods ended June 30, 2013, respectively, and 1,151 shares related to stock options for both the three and six month periods ended June 30, 2012. These shares were excluded due to their antidilutive effect.
