Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

The fair value of each option and equity warrant award is estimated on the date of grant using a Black-Scholes-Merton option pricing valuation model. Expected volatility is based on the historical volatility of the price of the Company’s stock. The risk-free interest rate is based on U.S. Treasury issues with a term equal to the expected life of the option and equity warrant. The Company uses historical data to estimate expected dividend yield, expected life and forfeiture rates. There were 800,000 and 855,000 options or equity warrants granted in the six months ended June 30, 2015 and 2014, respectively.

Stock option for employees' activity during the six months ended June 30, 2015 is as follows:
