Option valuation models require the input of highly subjective assumptions. The fair value of stock-based payment awards was estimated using the Black-Scholes option model with a volatility figure derived from using the Company's historical stock prices. The Company accounts for the expected life of options based on the contractual life of options for non-employees. For employees, the Company accounts for the expected life of options in accordance with the "simplified" method, which is used for "plain-vanilla" options, as defined in the accounting standards codification. The risk-free interest rate was determined from the implied yields of U.S. Treasury zero-coupon bonds with a remaining life consistent with the expected term of the options.

In applying the Black-Scholes option pricing model, the Company used the following assumptions in 2020:
