[1] Expected life: For employee grants, the expected term of options granted is determined using historical data, the contractual terms of the options granted and other factors.
[2] Risk-free interest rate: The rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected life of the options.
[3] Volatility: The expected volatility of the Company’s common stock is calculated by using the historical daily volatility of the Company’s stock price calculated over a period of time representative of the expected life of the options.
[4] Dividend yield: The dividend yield rate is not considered in the model, as the Company has not established a dividend policy for the stock and, other than the one-time special dividend, the Company has not historically paid any dividends.
