Schedule of Share-based Payment Award, Stock Options, Valuation Assumptions | The fair value of each share purchase option under the Company's ESPP is estimated on the date of grant using the Black-Scholes-Merton option valuation model with the weighted average assumptions noted in the following table. The expected term of the ESPP represents the term of the offering period of each option. The risk-free rate is based upon the estimated life and on the U.S. Treasury yield curve in effect at the time of grant. Expected volatility is based on the historical volatility on the Company’s stock.
