Assumptions regarding volatility, expected term, dividend yield and risk-free interest rate are required under the Black-Scholes model. The volatility assumption is based on the Company’s historical experience. The risk-free interest rate is based on a U.S. Treasury note with maturity similar to the option award’s expected life. The expected life represents the average period of time that options granted are expected to be outstanding. The assumptions for volatility, expected life, dividend yield and risk-free interest rate for the options granted are as follows: Nine Months Ended September 30, 2020 Risk-free interest rate 0.21% - 1.67% Expected life in years 3.25 - 6.00 Expected Volatility 103.56% - 110.71% Expected dividend yield 0% The share-based compensation cost resulting from stock option grants, including those previously granted and vesting over time, is expensed ratably over the respective vesting periods.
