STOCK COMPENSATION EXPENSE [Abstract]  
Assumption used in the Black-Scholes option-pricing model
The fair value of the Company's employee stock options granted is estimated at the date of grant using the Black-Scholes option-pricing model. This model requires the input of highly subjective assumptions, changes to which can materially affect the fair value estimate. Additionally, there may be other factors that would otherwise have a significant effect on the value of employee stock options granted but are not considered by the model. The assumptions used in the Black-Scholes option-pricing model are as follows
