[1] During the first quarter of 2014, the Company revised its assumption for expected volatility by switching from a peer-group average volatility to the Company’s three-year historical volatility in measuring the value of the derivative liabilities mentioned above. Prior to 2011, the occurrence of certain corporate events would not have made the historical volatility calculations meaningful or accurate if included. This reduction in volatility led to a reduced valuation for both the Warrant and PIK Note derivative liabilities of approximately $118,500 and $126,000, respectively. The remaining decrease in the valuation is attributable to the decline in the Company’s stock price.
