Schedule of Fair Value of Option Granted Share-based Payment Award Stock Options Valuation Assumptions
The fair value for options granted for the years ended December 31, 2021, 2020 and 2019 was estimated on the date of grant using a Black-Scholes-Merton options pricing model with the following weighted average assumptions:
 
    
Years ended December 31,
    
2021
  
2020
  
2019
Dividend yield
(1)
   0%    0%    0%
Expected volatility

Risk-free interest rate

Expected term (years)
(4)
  
5.27-6.25
  
5.27-6.08
  
6.02-6.08
 
(1)
No dividends were paid during the years ending December 31, 2021, 2020 and 2019.
(2)
The expected volatility was calculated based upon historical stock price movements of similar publicly traded peer companies over the most recent periods ending on the grant date, equal to the expected term of the options, as adequate historical experience is not available to provide a reasonable estimate.
(3)
The risk-free interest rate is based on the yield from U.S. treasury bonds with an equivalent term to the expected term of the options.
(4)
The expected term of options granted is calculated using the simplified method for “plain vanilla” stock options awards.
