| Fair Value Measurements |
4. Fair Value Measurements We record our financial assets and liabilities at fair value. The accounting standard for fair value provides a framework for measuring fair value, and defines fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The accounting standard establishes a three-tier hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:
| | • |
Level 1-Quoted prices in active markets for identical assets or liabilities. We consider a market to be active when transactions for the asset occur with sufficient frequency and volume to provide pricing information on an ongoing basis. |
| | • |
Level 2-Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are 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. The valuation of Level 3 assets or liabilities requires the use of significant management judgments or estimation. |
Our fair value hierarchies for our financial assets and liabilities which require fair value measurement on a recurring basis are as follows:
| | | Total | | | Quoted Prices in
Active Markets for
Identical Items
Level 1 | | | Significant Other
Observable Inputs
Level 2 | | | Significant
Unobservable

The following table sets forth a summary of the changes in the fair value of our Level 3 financial liabilities, which were measured at fair value on a recurring basis.
| | | Warrant liability | | | Convertible debt | |
| Beginning balance December 31, 2013 | | $ | 377,747 | | | $ | 5,062,417 | |
| Transfer to equity upon settlement | | | (377,747 | ) | | | (5,062,417 | ) |
| Fair value of warrants on date of issuance | | | 10,613,550 | | | | - | |
| Change in fair value of warrants during the period | | | 16,979,000 | | | | - | |
| Ending balance June 30, 2014 | | $ | 27,592,550 | | | $ | - | |
The fair value of each warrant was determined using a lattice model with the following assumptions:
| | | Six months ended
June 30, | |
| | | 2014 | | | 2013 | |
| Dividend yield | | | - | | | | N/A | |
| Risk-free interest rate | | | 0.69-1.45 | % | | | N/A | |
| Current share price | | $ | 1.47 | | | | N/A | |
| Expected term (in years) | | | 2.55-4.55 | | | | N/A | |
| Volatility | | | 70-75 | % | | | N/A | |
| Periodic rate | | |
0.18-66 | % | | | N/A | |
| Periods in the model | | | 10 | | | | N/A | |
During the six months ended June 30, 2014 the warrant liability and convertible debt outstanding as of December 31, 2013 were settled in transactions related to the Merger. See Note 3, The Merger, Offering and Other Related Transactions.
