5. Fair Value Measurements

 

Financial Instruments Measured and Recorded at Fair Value on a Recurring Basis

 

The Company measures and records certain financial instruments at fair value on a recurring basis. Fair value is based on the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, under a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value as follows:

 

  Level 1 - quoted market prices for identical assets or liabilities in active markets.
       
  Level 2 - observable prices that are based on inputs not quoted on active markets, but corroborated by market data.
       
  Level 3 - unobservable inputs reflecting management’s assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment.

 

The Company classifies assets and liabilities measured at fair value in their entirety based on the lowest level of input that is significant to their fair value measurement. No financial assets were measured on a recurring basis at December 31, 2016 and 2015. The following tables set forth the financial liabilities measured at fair value on a recurring basis by level within the fair value hierarchy at December 31, 2016 and 2015.

The Company did not have any transfers of assets and liabilities between Level 1 and Level 2 of the fair value measurement hierarchy during the years ended December 31, 2016 and 2015. The following table presents a reconciliation of the derivative liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the years ended December 31, 2016 and 2015 (in thousands):

There were no warrant derivatives issued in 2016. In 2015 there were $9.5 million of warrant derivatives issued for the September 2015 offering were recorded as a loss and included in the change in fair value of derivative liabilities per the consolidated statements of operations since the value of the derivative liabilities issued exceeded the proceeds received from the issuance of common stock and warrants. See Note 8 for additional information.

 

Common Stock Warrants

 

The Company has issued certain warrants to purchase shares of common stock, which are considered mark-to-market liabilities and are re-measured to fair value at each reporting period in accordance with accounting guidance.

 

The assumptions used in estimating the common stock warrant liability at December 31, 2016 and 2015 were as follows:

 

    December 31, 2016     December 31, 2015  
Weighted-average risk free interest rate     0.92 %     1.71 %
Weighted-average expected life (in years)     2.5       3.7  
                 
Expected dividend yield     0 %     0 %
Weighted-average expected volatility     136 %     119 %

 

Other Financial Instruments

 

The Company’s recorded values of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair values based on their short-term nature. The recorded value of notes payable approximates the fair value as the interest rate approximates market interest rates.
