Fair Value Measurements

Fair value is defined as the exchange 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. The accounting guidance for fair value establishes a framework for measuring fair value and a fair value hierarchy that prioritizes the inputs used in valuation techniques. The accounting standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value, which are the following:

Level 1 – Observable inputs, such as quoted prices in active markets for identical assets or liabilities.

Level 2 – Observable inputs, either directly or indirectly, other than quoted prices in active markets for similar assets or liabilities, that are not active or other inputs that are not observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities; therefore, requiring an entity to develop its own valuation techniques and assumptions.

The following tables set forth the Company’s fair value hierarchy for its financial assets and liabilities measured at fair value on a recurring basis as of June 30, 2015 and December 31, 2014 as follows (in thousands):

During the six-month period ended June 30, 2015, there were no transfers between Level 1, Level 2, or Level 3 assets or liabilities reported at fair value on a recurring basis and the valuation techniques used did not change compared to the Company’s established practice.

The estimated fair value of the foreign exchange options as of June 30, 2015, was de minimus.  The estimated fair value of the foreign exchange options at June 30, 2015, and December 31, 2014, was determined using readily observable market inputs from actively quoted markets obtained from various third-party data providers. These inputs, such as spot rate, forward rate and volatility have been derived from readily observable market data, meeting the criteria for Level 2 in the fair value hierarchy. The change in the fair value is recorded in the other income (expense), net line of the condensed consolidated statements of comprehensive loss.
 
The estimated fair value of the contingent warrant liabilities at June 30, 2015, and December 31, 2014, was determined using the Black-Scholes Model, which requires inputs such as the expected term of the warrants, volatility and risk-free interest rate. These inputs are subjective and generally require analysis and judgment to develop. The Company’s common stock price represents a significant input that affects the valuation of the warrants. The change in the fair value is recorded as a gain or loss in the revaluation of contingent warrant liabilities line of the condensed consolidated statements of comprehensive loss.

The estimated fair value of the contingent warrant liabilities was estimated using the following range of assumptions at June 30, 2015, and December 31, 2014:

 
 
June 30,
2015
   
December 31,
2014

The fair value of the Company’s outstanding interest bearing obligations is estimated using the net present value of the payments, discounted at an interest rate that is consistent with market interest rates, which is a Level 2 input.  The carrying amount and the estimated fair value of the Company’s outstanding interest bearing obligations at June 30, 2015, and December 31, 2014, are as follows (in thousands):
