The Company estimates the fair value of each stock option on the grant date using the Black-Scholes-Merton valuation model, which requires several estimates including an estimate of the fair value of the underlying common stock on grant date. The expected volatility was based on an average of the historical volatility of a peer group of similar companies. The expected term was calculated utilizing the simplified method. The risk-free interest rate was based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the option. The following weighted average assumptions were used in the calculation to estimate the fair value of options granted to employees during the six months ended June 30, 2016 (no options were granted for the six months ended June 30, 2017):

 

    Six Months Ended  
    June 30, 2016

Weighted-average expected life (in years)     6.30  
Expected dividend yield     0.00 %
