The Company used the following assumptions to estimate the fair values of the options granted for the years ended: December 31, December 31, 2015 2014 Dividend yield - - Expected volatility 71.55 - 165.7% 74.95 – 120.64% Risk-free interest rate 0.02 – 1.32% 0.11 – 2.00% Expected life (years) 0.10 – 4.25 1.0 – 7.89 Inputs used in these models are determined as follows: 1. The expected life represents the weighted-average period the awards are expected to remain outstanding and is a derived output of the option pricing models. The expected life is impacted by all of the underlying assumptions and calibration of the Company’s models. 2. The requisite service period for market-based stock option awards is a derived output of the hybrid Monte Carlo-Trinomial Lattice model. 3. Volatility is based on the average historical volatility levels of a representative peer group or the Company’s common stock depending on the life of the options. 4. The risk-free interest rate is based on the implied yield available on U.S. Treasury zero- coupon issues over the equivalent contractual lives of the options.
