Net Income (Loss) Per Share [Abstract]  
Net Income (Loss) Per Share
Note 9: Net Income (Loss) Per Share
     Basic net income (loss) per share is computed using the weighted-average number of common shares outstanding for the period. Diluted net income (loss) per share is computed by adjusting the weighted-average number of common shares outstanding for the effect of dilutive potential common shares outstanding during the period. Potential common shares included in the diluted calculation consist of incremental shares issuable upon the exercise of outstanding stock options calculated using the treasury stock method.
     The following table sets forth the calculation of basic and diluted net income (loss) per share (in thousands, except per share amounts):

     All dilutive options outstanding as of June 30, 2011 and 2010 were included in the computation of diluted net income (loss) per share for the three months.
     For the six months ended June 30, 2011, options to purchase approximately 300,000 shares of common stock were not included in the calculation of net loss per share because the effect would have been anti-dilutive.
     For the six months ended June 30, 2010, options to purchase approximately 300,000 shares of common stock with exercise prices greater than the average fair value of the Company’s stock were not included in the calculation because the effect would have been anti-dilutive.
