[1] The warrants are valued using a trinomial lattice valuation methodology because that model embodies all of the relevant assumptions that address the features underlying these instruments. Significant assumptions used in the model at June 30, 2016 included the market price of our common stock, an expected dividend yield of zero, the remaining period to the expiration date of the warrants, expected volatility of our common stock over the remaining life of the warrants of 49.5%, estimated based on a review of our historical volatility, and risk-free rates of return of 0.7% for the 2013 warrants based on constant maturity rates published by the U.S. Federal Reserve, applicable to the remaining life of the warrants. We also take into consideration a probability assumption for anti-dilution.
