Options: We estimate the fair value of each option award on the date of grant using the Black-Scholes option valuation model. We
then recognize the grant date fair value of each option as compensation expense ratably using the straight-line attribution method over
the service period (generally the vesting period). The Black-Scholes model incorporates the following assumptions:
|
● |
Expected
volatility - we estimate the volatility of our share price at the date of grant using a “look-back” period which coincides
with the expected term, defined below. We believe using a “look-back” period which coincides with the expected term is
the most appropriate measure for determining expected volatility. |
|
● |
Expected
term - we estimate the expected term using the “simplified” method, as outlined in Staff Accounting Bulletin No. 107,
“Share-Based Payment.” |
|
● |
Risk-free
interest rate - we estimate the risk-free interest rate using the U.S. Treasury yield curve for periods equal to the expected term
of the options in effect at the time of grant. |
|
● |
Dividends
- we use an expected dividend yield of zero because we have not declared or paid a cash dividend, nor do we have any plans to declare
a dividend. |
We
used the following weighted-average assumptions to estimate the fair value of the options granted for the periods indicated:
