That model incorporates various assumptions in the valuation of stock-based awards relating to the risk-free rate of interest to be applied, the estimated dividend yield and expected volatility of the Company's Common Stock. The risk-free rate of interest is the U.S. Treasury yield curve for periods within the expected term of the option at the time of grant. The expected volatility is based on historical volatility of the Company's Common Stock. The valuation assumptions we have applied to determine the value of warrants granted in 2020 Historical stock price volatility: The Company used the weekly closing price to calculate historical annual volatility. Risk-free interest rate: The Company bases the risk-free interest rate on the rate payable on US treasury securities with a similar maturity in effect at the time of the grant, which was a range from .42% 1.65%. Expected life: The expected life of the warrants represents the period of time warrants were expected to be outstanding. The Company used an expected life of 5 Dividend yield: The estimate for dividend yield is 0%, not 2020 2019 not Estimated forfeitures: When estimating forfeitures, the Company considers historical terminations as well as anticipated retirements.
