8. STOCK-BASED COMPENSATION

 

We account for stock-based compensation in accordance with Codification Topic 718, Compensation-Stock Compensation, which generally requires us to recognize non-cash compensation expense for stock-based payments using the fair-value-based method. The fair value of each stock option grant has been estimated on the date of grant using the Black-Scholes option pricing model. Accordingly, we recorded compensation expense pertaining to stock-based compensation of $9,000 and $10,000 during the three-month periods ended June 30, 2012 and 2011, respectively, and $18,000 during both of the six-month periods ended June 30, 2012 and 2011.
