Schedule of Fair Value Assumptions

The fair value of an option award is estimated on the date of grant using the Black–Scholes option valuation model, using the following assumptions primarily based on historical data:

 

      Years Ended December 31,  
      2024       2023  
Risk-free interest rate     0.3 - 4.3 %     0.3 - 4.0 %
Expected volatility (1)     0.0% - 161.7 %     0.0% - 72.5 %
Expected dividend yield     – %     – %
Expected life (years) (2)     0 - 7.6       0 - 7.6  

 

(1) Expected volatility was determined using historical volatility.

 

(2) For certain options, the simplified method is utilized to determine the expected life due to the lack of historical data.
