Debt Disclosure [Abstract]  



On September 30, 2016, the Company entered into a loan agreement with Solar, in its capacity as administrative and collateral agent and as lender. Pursuant to the loan agreement, Solar was providing the Company with a 48-month secured term loan in the amount of $15.0 million.  The term loan bore interest at a floating rate equal to the LIBOR rate in effect plus 8.49%.  The Solar term loan was paid in full in 2019.

On March 7, 2019, the Company entered into a Senior Convertible Note Purchase Agreement (the “Note Purchase Agreement”) with Puissance Life Science Opportunities Fund VI (“Puissance”).  Pursuant to the Note Purchase Agreement, on March 7, 2019, the Company issued and sold to Puissance $16.0 million aggregate principal amount of its Notes, resulting in $14.7 million in net proceeds after deducting $1.3 million for an advisory fee and other issuance costs.  The Company used the net proceeds to pay the remaining outstanding Solar term loan in full and recorded a loss on debt extinguishment of $0.8 million during the year ended December 31, 2019.  The loss on debt extinguishment of $0.8 million for the year ended December 31, 2019, was recognized as the difference between the reacquisition price of the outstanding Solar debt of $15.9 million and the $15.1 million net carrying value of the Solar debt obligation prior to repayment.  In accordance with ASC 470-10-45-14(a), the Company reclassified the short-term portion of the Solar term loan on the balance sheet as of December 31, 2018 to long-term given the Company had the intent and ability to refinance the short-term obligation on a long-term basis.  

In April 2019, Puissance converted $2.0 million of the Notes for 1,626,000 shares of common stock.  Upon conversion of the $2.0 million of the Notes, the Company recognized a $0.2 million extinguishment loss which represents the difference between the total net carrying amount of the convertible debt and derivative liability of $2.8 million and the fair value of the consideration issued of $3.0 million.  

As of December 31, 2019, the Company’s $11.5 million in convertible debt and derivative liability consists of the convertible debt balance of $8.3 million presented net of the unamortized debt issuance costs allocated to the convertible debt of $0.5 million and the bifurcated embedded conversion option derivative liability of $3.2 million.  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, at its initial fair value of $7.0 million as the interest make-whole provision is settled in shares of common stock.  Debt issuance costs of $0.6 million initially allocated to the derivative liability were written off upon issuance of the Notes and were recognized in the loss on the fair value adjustment for the derivative liability for year ended December 31, 2019.  For the year ended December 31, 2019, the Company recognized in other expense (income) on the consolidated statements of operations, a gain of $1.6 million on the fair value adjustment for the derivative liability and $1.1 million in amortization of debt issuance costs and discount related to the Notes.  

The Company estimated the fair value of the convertible debt and derivative liability using a binomial lattice valuation model and Level 3 inputs. At December 31, 2019, the fair value of the senior convertible notes is $11.7 million.

The Notes were issued and sold for cash at a purchase price equal to 100% of their principal amount, in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”), due to the Notes being issued to one financially sophisticated investor. The Notes bear interest at a rate of 6.0% per annum payable semiannually in arrears on March 15 and September 15 of each year, beginning September 15, 2019. The Notes will mature on March 15, 2025, unless earlier converted, redeemed or repurchased. The Notes constitute general, senior unsecured obligations of the Company.

The holder of the Notes may convert their Notes at their option at any time prior to the close of business on the business day immediately preceding March 15, 2025 into shares of the Company’s common stock. The initial conversion rate is 739.0983 shares of common stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of approximately $1.35, and is subject to adjustment in certain events described in the Note Purchase Agreement. The Holder upon conversion may also be entitled to receive, under certain circumstances, an interest make-whole payment payable in shares of common stock. In addition, following certain corporate events that occur prior to the maturity date, the Company will, in certain circumstances, increase the conversion rate if the holder elects to convert its Notes in connection with such a corporate event. Subject to adjustment in the conversion rate, the number of shares that the Company may deliver in connection with a conversion of the Notes, including those delivered in connection with an interest make-whole payment, will not exceed a cap of 813 shares of common stock per $1,000 principal amount of the Notes.  

On or after March 15, 2022, the Company has the right, at its election, to redeem all or any portion of the Notes not previously converted if the last reported sale price per share of common stock exceeds 130% of the conversion price on each of at least 20 trading days (whether or not consecutive) during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice. The redemption price will be 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.  If a “fundamental change” (as defined in the Note Purchase Agreement) occurs, then, subject to certain exceptions, the Company must offer to repurchase the Notes for cash at a repurchase price of 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the repurchase date.
