[1] The warrants are valued using a binomial lattice valuation methodology because that model embodies all of the relevant assumptions that address the features underlying these instruments. Significant assumptions used in this model at inception and as of September 30, 2013 included an expected remaining life of 2 years, an expected dividend yield of zero, estimated volatility range between 40% - 43%, and risk-free rates of return range between 0.31% - 0.40%. For the risk-free rates of return, we use the published yields on zero-coupon Treasury Securities with maturities consistent with the remaining term of the warrants and volatility is based on a weighted average of the historical volatility of our stock price and peer company stock price volatility. We also take into consideration a probability assumption for anti-dilution.
