Schedule of Share-based Payment Award, Stock Options, Valuation Assumptions | The fair value of each share purchase option under the Company's 2014 ESPP and 1999 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 2014 ESPP and the 1999 ESPP represents the term of the offering period of each option. The risk-free rate is based upon the estimated life and is based on the U.S. Treasury yield curve in effect at the time of grant. Expected volatility is based on a blended rate of the implied volatilities from traded options and historical volatility on the Company’s stock.
