[1] | Risk-free rate is the U.S. Treasury yield curve in effect as of the grant date for periods within the contractual life of the option.
[2] | Dividend yield is the level of dividends expected to be paid on the Company’s common stock over the expected term of the option.
[3] | Expected term represents the period of time that the options are expected to be outstanding. The simplified method of estimating the expected term is used since the Company does not have significant historical exercise experience for its stock options.
[4] | Volatility is based on the historical volatilities of the Company’s stock and the stock of comparable peer companies.
