4.  Fair Value Measurements

Fair value is defined as the price that would be received from selling an asset or the amount that would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company applies ASC 820, which establishes a framework for measuring fair value and a fair value hierarchy that prioritizes the inputs used in valuation techniques. ASC 820 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 – Quoted prices in active markets for identical assets or liabilities.

Level 2 – Observable inputs other than quoted prices in active markets for similar assets or liabilities.

Level 3 – Unobservable inputs.

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, 2013 and December 31, 2012.

Financial assets and liabilities carried at fair value as of June 30, 2013 and December 31, 2012 were classified as follows (in thousands):

The fair value of the foreign exchange options at June 30, 2013 and December 31, 2012 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 fair value of the contingent warrant liabilities was determined at June 30, 2013 and December 31, 2012 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 significant analysis and judgment to develop.

The fair value of the contingent warrant liabilities was estimated using the following range of assumptions at June 30, 2013 and December 31, 2012:

For the three and six months ended June 30, 2013, the Company recognized net increases of $1.8 million and $14.6 million, respectively, in the estimated fair value of the contingent warrant liabilities resulting in recognized losses in the revaluation of contingent warrant liabilities line of the condensed consolidated statements of comprehensive loss.

For the three and six months ended June 30, 2012, the Company recognized net increases of $2.2 million and $16.5 million, respectively, in the estimated fair value of the contingent warrant liabilities resulting in recognized losses in the revaluation of contingent warrant liabilities line of the condensed consolidated statements of comprehensive loss.
