Warrant Liability [Abstract] |
Warrant Liability |
Note 13. | Warrant Liability
The warrant issued to Perceptive in connection with the August 16, 2016 Loan Agreement had certain rights and preferences including anti-dilution adjustments so that, upon exercise, they would represent 4.5% of the Company’s fully diluted common stock on an as converted basis, subject to dilution for certain financing transactions including the issuance of shares upon termination of our Performance Unit Plans. The warrant also provided Perceptive with a put right which, if exercised under certain circumstances, would require the Company to purchase the warrant for $3,000 within the first year of the loan or $5,000 thereafter. These re-purchase terms may require net-cash settlement, and as a result, the appraised value of this warrant at the time of issuance of $5,800 was classified as a liability, rather than as a component of equity, and is treated as a debt discount, with the unamortized portion applied to reduce the face amount of the loan in the accompanying Consolidated Balance Sheet. The Company used a third-party valuation to assist in determining the fair value of the warrant due to the absence of available Level 1 and Level 2 inputs prior to the IPO date. The fair values for periods prior to the IPO date were based on unobservable Level 3 inputs. The first step in determining the fair value of the warrant liability was to determine the value of the aggregate equity of the Company which was estimated utilizing the income and market valuation approaches. A probability weighted return model was then utilized to allocate the aggregate equity value of the Company to the underlying securities. Estimates and assumptions impacting the fair value measurement include the following factors: the progress of the Company’s pipeline products since the prior valuations, including status of clinical trials; the Company’s progress towards an IPO; a discount rate of 24.5% for the nine months ended September 30, 2017 and a volatility rate of 90% for the nine-month period ended September 30, 2017. Immediately prior to pricing of the Company’s initial public offering, Perceptive received 863,400 shares of common stock issuable pursuant to the automatic exercise of warrants from APL’s ownership interest at a total price of $116. As a result, the warrant liability of $12,951 was reclassified to additional paid in capital during the third quarter of 2018. A Level 1 market pricing of $15.00, the initial price at which the Company’s common stock was offered, was used in determining fair value as of the warrants conversion date. A roll-forward of warrant liability is as follows:
