| Warrant Liability and Fair Value | 9. Warrant Liability and Fair Value
Pursuant to the Company’s Offering, the Company sold 8,000,000 units, which subsequently separated into one warrant and one share of common stock. The Sponsor also purchased 4,000,000 warrants, exercisable for 1,142,800 shares of the Company’s common stock, in a private placement in connection with the initial public offering. The warrants expire on April 8, 2018. The warrants issued contain a cashless exercise feature and a restructuring price adjustment provision in the event of any merger or consolidation of the Company with or into another corporation, subsequent to the initial business combination, where the surviving entity is not the Company and whose stock is not listed for trading on a national securities exchange or on the OTC Bulletin Board, or is not to be so listed for trading immediately following such event (the “Applicable Event”). The exercise price of the warrant is decreased immediately following an Applicable Event by a formula that causes the warrants to not be indexed to the Company’s own stock.
As a result, the warrants are considered a derivative and the liability has been classified as a liability on the Balance Sheet. Management uses the quoted market price of the warrants to calculate the warrant liability which was determined to be $1 thousand and $289 thousand at December 31, 2017 and 2016, respectively. This valuation is revised on a quarterly basis until the warrants are exercised or they expire with the changes in fair value recorded in the statement of operations. Any change in the market value of the warrant liability is recorded as Other Income (Expense) in the Statement of Comprehensive Loss.
The fair value of the derivative warrant liability was determined by the Company using the quoted market prices for the publicly traded warrants. On reporting dates where there are no active trades the Company uses the last reported closing trade price of the warrants to determine the fair value (Level 2). There were no transfers between Level 1, 2 or 3 during the years ended December 31, 2017 and 2016.
The following table presents information about the Company’s warrant liability that is measured at fair value on a recurring basis, and intangible assets on a non-recurring basis and indicates the fair value hierarchy of the valuation techniques the Company used to determine such fair value. In general, fair values determined by Level 1 inputs use quoted prices (unadjusted) in active markets for identical assets or liabilities. Fair values determined by Level 2 inputs use data points that are observable such as quoted prices, interest rates and yield curves. Fair values determined by Level 3 inputs are unobservable data points for the asset or liability, and includes situations where there is little, if any, market activity for the asset or liability:
