The Company issues awards to employees, qualified consultants and directors that generally vest over time based solely on continued employment or service during the related vesting period and are exercisable over a five to ten year service period. Options are generally granted with an exercise price equal to the market price of the Company's stock at the date of grant. |
|
The fair value of each stock-based award is estimated on the grant date using the Black-Scholes option-pricing model. Expected volatilities are based on the historical volatility of the Company's stock price. The expected term of options granted subsequent to the adoption ASC 718 is derived using the simplified method as defined in the SEC's SAB No. 107. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury interest rates in effect at the time of grant. The fair value of options granted was estimated using the following weighted-average assumptions: |
