Schedule of Share-based Payment Award, Stock Options, Valuation Assumptions [Table Text Block]
The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. The expected annual volatility is based on the historical volatility of our stock and other factors. We use historical data to estimate option exercises and employee termination within the pricing model. The expected term of options granted represents the period of time that options are expected to be outstanding. The following table summarizes the assumptions made in determining the fair value of stock options granted in the fiscal years indicated:
