Derivative Liability

In connection with the Company’s issuance of its Notes, the Company bifurcated the embedded conversion option, inclusive of the interest make-whole provision and make-whole fundamental change provision, and recorded the embedded conversion option as a long-term derivative liability in the Company’s balance sheet in accordance with ASC 815, Derivatives and Hedging.  The convertible debt and derivative liability associated with the Notes are presented in total on the accompanying unaudited balance sheet as the convertible debt and derivative liability.  The derivative liability will be remeasured at each reporting period using the binomial lattice model with changes in fair value recorded in the statements of operations in other (income) expense.  For the three and six months ended June 30, 2019, the Company recorded a gain of $1.3 million and a loss of $2.1 million due to the change in fair value of the derivative liability.  In April 2019, Puissance converted $2.0 million of the Notes for 1,626,000 shares of common stock.

Warrants Associated with June 2016 and March 2018 Public Offerings

The outstanding warrants associated with the June 2016 and March 2018 public offerings contain a provision where the warrant holder has the option to receive cash, equal to the Black-Scholes fair value of the remaining unexercised portion of the warrant, as cash settlement in the event that there is a fundamental transaction (contractually defined to include various merger, acquisition or stock transfer activities). Due to this provision, ASC 480, Distinguishing Liabilities from Equity, requires that these warrants be classified as liabilities. The fair values of these warrants have been determined using the Black-Scholes valuation model, and the changes in the fair value are recorded in the accompanying statements of operations.  During the three months ended June 30, 2019 and 2018, the Company recorded a gain of $2.0 million and a loss of $2.9 million, respectively, due to the change in fair value of the warrant liabilities.  For the six months ended June 30, 2019 and 2018, the Company recorded a loss of $4.5 million and a gain of $0.7 million, respectively, due to the change in fair value of the warrant liabilities.  As of June 30, 2019, the fair value of the warrant liabilities was $5.5 million.

Warrant Associated with Solar Loan Agreement

Pursuant to the loan agreement, on the Closing Date the Company issued to Solar the warrant to purchase an aggregate of up to 122,435 shares of the Company’s common stock at an exercise price of $3.6754 per share. The warrant will expire five years from the date of the grant. The warrant was classified as equity and recorded at its relative fair value at issuance in the stockholders' equity section of the balance sheet.
