Summary of valuation assumptions used to value stock options
Management estimated the fair value of options granted using the Black-Scholes option-pricing model.  This model was originally developed to estimate the fair value of exchange-traded equity options, which (unlike employee stock options) have no vesting period or transferability restrictions.  As a result, the Black-Scholes model is not necessarily a precise indicator of the value of an option, but it is commonly used for this purpose.  The Black-Scholes model requires several assumptions, which management developed based on historical trends and current market observations.
