Derivative Liability - Warrants and Derivative Liability - Conversion Option | NOTE 6: DERIVATIVE LIABILITY - WARRANTS AND DERIVATIVE LIABILITY – CONVERSION OPTION A summary of quantitative information with respect to valuation methodology and significant unobservable inputs used for the Company’s common stock purchase warrants that are categorized within Level 3 of the fair value hierarchy for the three months ended 2016 and 2015 is as follows: Share Purchase Warrants Weighted Average Inputs for the Period Date of valuation For the Quarter 2016 For the Quarter 2015 Exercise price $ 0.70 $ 0.98 Contractual term (years) 4.00 4.00 Volatility (annual) 150.00 % 158.00 % Risk-free rate 1.05 % 1.00 % Dividend yield (per share) 0 % 0 % The foregoing assumptions are reviewed quarterly and are subject to change based primarily on management’s assessment of the probability of the events described occurring. Accordingly, changes to these assessments could materially affect the valuations. Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis Financial assets and liabilities measured at fair value on a recurring basis are summarized below and disclosed on the balance sheet under Derivative liability – warrants: As of March 31, 2016 Fair Value Measurements Fair Value Level 1 Level 2 Level 3 Total Derivative liability - warrants $ 29,489,000 — — $ 29,489,000 $ 29,489,000 Total $ 29,489,000 — — $ 29,489,000 $ 29,489,000 As of December 31, 2015 Fair Value Measurements Fair Value Level 1 Level 2 Level 3 Total Derivative liability - warrants $ 26,493,000 — — $ 26,493,000 $ 26,493,000 Total $ 26,493,000 — — $ 26,493,000 $ 26,493,000 There were no transfers between Level 1, 2 or 3 during the three months ended March 31, 2016. The following table presents changes in Level 3 liabilities measured at fair value for the three months ended March 31, 2016: Derivative liability –warrants Balance – January 1, 2016 $ 26,493,000 Change in fair value of warrant liability 2,996,000 Balance – March 31, 2016 $ 29,489,000 The valuation of warrants is subjective and is affected by changes in inputs to the valuation model including the price per share of common stock, the historical volatility of the stock price, risk-free rates based on U.S. Treasury security yields, the expected term of the warrants and dividend yield. Changes in these assumptions can materially affect the fair value estimate. The Company could ultimately incur amounts to settle the warrant at a cash settlement value that is significantly different than the carrying value of the liability on the financial statements. The Company will continue to classify the fair value of the warrants as a liability until the warrants are exercised, expire, or are amended in a way that would no longer require these warrants to be classified as a liability. Changes in the fair value of the common stock warrants liability are recognized as a component of other income (expense) in the Statements of Operations. |
