Valuation Assumptions

 

The fair value of each stock option award was calculated on the date of grant using the Black-Scholes option pricing model. The following weighted average assumptions were used for the six months ended June 30, 2020 and 2019.

 

    Six Months Ended
    June 30,
    2020   2019
Risk-free interest rate   0.58    %   2.25    %
Expected life (years)   6.00        6.00     
Expected dividend yield   -    %   -    %
Expected volatility   77.57    %   81.67    %

 

The risk-free interest rate assumption is based upon published interest rates appropriate for the expected life of our employee stock options.

 

The expected life of the stock options represents the weighted-average period that the stock options are expected to remain outstanding and was determined based on historical experience of similar awards, giving consideration to the contractual terms of the stock-based awards, vesting schedules and expectations of future employee behavior as influenced by changes to the terms of its stock-based awards.

 

The dividend yield assumption is based on our history of not paying dividends and no future expectations of dividend payouts.

 

The expected volatility in 2020 and 2019 is based on the historical publicly traded price of our common stock.
