The risk-free interest rate is based on United States Treasury yields in effect at the date of grant for periods corresponding to the expected option term. The expected option term represents the weighted average period of time that options granted are expected to be outstanding, based on vesting schedules and the contractual term of the options. Company volatility is based on the historical volatility of the Company’s common stock over a period of time corresponding to the expected option term. Expected dividends are based on the Company’s common stock cash dividend rate at the date of grant.
