Fair Value Measurements
A hierarchy for inputs used in measuring fair value is in place that distinguishes market data between observable independent market inputs and unobservable market assumptions by the reporting entity. The hierarchy is intended to maximize the use of observable inputs and minimize the use of unobservable inputs by requiring that the most observable inputs be used when available. Three levels within the hierarchy may be used to measure fair value:
In conjunction with the debt financings completed in October 2016 and January 2018, the Company issued two warrants for the purchase of up to an aggregate of 1,239,286 shares of the Company's common stock, which remained unexercised and outstanding at June 30, 2019. The warrant issued in conjunction with the October 21, 2016 debt financing (Hale warrant) for the purchase of up to 314,286 shares of the Company's common stock expires on October 21, 2026, has an exercise price of $2.80 per share and is transferable. The warrant issued in conjunction with the January 12, 2018 debt financing (ESW warrant) for the purchase of up to 925,000 shares of the Company's common stock expires on January 12, 2028, has an exercise price of $1.96 per share and is transferable. Additionally, on August 31, 2018, the Company issued a warrant to a sales partner, iStudy Co., Ltd., (iStudy warrant) for the purchase of up to 100,000 shares of the Company's common stock; the warrant expires on August 31, 2028, has an exercise price of $2.43 per share and is transferable. The Hale warrant and ESW warrant contain a cash settlement feature upon the occurrence of a certain events, essentially the sale of the Company as defined in the warrant agreements. Upon a sale of the Company, the holder of the iStudy warrant may exercise the warrant or may elect to receive the same consideration as it would have been entitled to receive upon the occurrence of such transaction if it had been the holder of the shares then issuable upon such exercise of the warrant. As a result of these features, the warrants are subject to derivative accounting as prescribed under ASC 815. Accordingly, the fair value of the warrants on the dates of issuance was recorded in the Company’s condensed consolidated balance sheets as a liability.
The warrant liability was recorded in the Company's condensed consolidated balance sheets at its fair value on the respective dates of issuance and is revalued on each subsequent balance sheet date until such instrument is exercised or expires, with any changes in the fair value between reporting periods recorded as other income or expense. The Company recorded non-cash losses of $1.4 million and $278,000 during the three months ended June 30, 2019 and 2018, respectively, a non-cash loss of $1.7 million during the six months ended June 30, 2019, and a non-cash gain $109,000 for the six months ended June 30, 2018 resulting from the change in fair value of the warrant liability. The increase in fair value for the three months ended June 30, 2019, the three months ended June 30, 2018 and the six months ended June 30, 2019 was primarily driven by corresponding increases in the Company’s stock price of 69%, 25% and 118% for the respective periods. The decrease in fair value during the six months ended June 30, 2018 was primarily driven by a decrease in the Company’s stock price of 7% during the period.
The Company estimates the fair value of this liability using option pricing models that are based on the individual characteristics of the warrants on the valuation date, which include assumptions for expected volatility, expected life and risk-free interest rate, as well as the present value of the minimum cash payment component of the instrument for the warrants, when applicable. Changes in the assumptions used could have a material impact on the resulting fair value. The primary inputs affecting the value of the warrant liability are the Company’s stock price and volatility in the Company's stock price, as well as assumptions about the probability and timing of certain events, such as a change in control or future equity offerings. Increases in the fair value of the underlying stock or increases in the volatility of the stock price generally result in a corresponding increase in the fair value of the warrant liability; conversely, decreases in the fair value of the underlying stock or decreases in the volatility of the stock price generally result in a corresponding decrease in the fair value of the warrant liability.
The Company’s liabilities measured at fair value on a recurring basis and the fair value hierarchy utilized to determine such fair values is as follows at June 30, 2019 and December 31, 2018 (in thousands):
The Company classified the warrant liability as Level 3 due to the lack of relevant observable market data over fair value inputs such as the probability-weighting of the various scenarios in the arrangements. The following table represents a rollforward of the fair value of the Level 3 instruments (significant unobservable inputs):
The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.
