STOCK BASED COMPENSATION

NOTE 8 – STOCK BASED COMPENSATION

 

The Company uses the Black-Scholes option pricing model to calculate the grant-date fair value of an award, with the following assumptions for 2015 and 2014: no dividend yield in both years, expected volatility, based on the Company’s historical volatility, 75% to 79% in 2015 and between 70.25% to 109% in 2014, risk-free interest rate between 1.44% to 1.70% in 2015 and between 0.58% to 2.08% in 2014 and expected option life of 5 to 5.75 years in 2015 and 2.13 to 7.25 years in 2014.

 

As of December 31, 2015, there was $209,618 of unrecognized compensation expense related to non-vested market-based share awards that is expected to be recognized through August 2018.

 

The following tables summarize all stock option and warrant activity of the Company during the year ended December 31, 2015 and 2014:
