Summary of Significant Accounting Policies

The accompanying unaudited financial statements and notes follow the same significant accounting policies as those described in the notes to the audited consolidated financial statements of the Company for the year ended December 31, 2018, except as described below.

Basic and Diluted Net Loss per Share of Common Stock

The Company calculates net loss per common share in accordance with FASB ASC 260, Earnings Per Share ("Topic 260”). Basic and diluted net loss per common share was determined by dividing net loss applicable to common stockholders by the weighted average number of common shares outstanding during the period.

The following potentially dilutive shares of common stock have not been included in the computation of diluted net loss per share for all periods as the result would be anti-dilutive:


Three Months Ended March 31,








Warrants to purchase Series C-1 Preferred








Warrants to purchase common stock associated with Solar Capital Ltd. loan agreement








Warrants to purchase common stock associated with June 2016 public offering








Warrants to purchase common stock associated with March 2018 public offering - Series 1







Warrants to purchase common stock associated with March 2018 public offering - Series 2








Stock options








Common stock associated with  6% convertible senior notes







Convertible Debt and Derivative Liability

In connection with the Company’s issuance of its 6.0% Convertible Senior Notes due 2025 (the “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 the derivative liability associated with the Notes are presented in total on the unaudited balance sheet as the convertible debt and derivative liability.  The convertible debt is carried at amortized cost.  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).  

Amortization of Debt Issuance Costs and Discount

The Company’s convertible debt is recorded net of debt issuance costs which comprised issuance costs and an advisory fee.  The portion of the debt issuance costs allocated to the convertible debt, based on the amount of proceeds allocated between the convertible debt and the derivative liability, is being amortized over the term of the convertible debt using the effective interest method.  Debt issuance costs allocated to the derivative liability were included in other expense as a component of the fair value adjustment for the three months ended March 31, 2019.  The Company's previous term loan with Solar Capital Ltd. (“Solar”), which was paid in full during the three months ended March 31, 2019 (see Note 6), was recorded net of debt discount which comprised issuance costs, customary closing and final fees, and the fair value of the warrants issued in conjunction with the term loan. The resulting debt discount was being amortized over the term of the term loan using the straight-line method, which approximates the effective interest method.  The amortization of debt issuance costs and discount is included in the accompanying unaudited statements of operations.

Recently Adopted Accounting Pronouncements

The Company adopted the FASB’s ASU No. 2016-02, Leases, or ASU 2016-02, on January 1, 2019, utilizing the modified retrospective basis.  ASU 2016-02 requires lessees to recognize a right-of-use asset and lease liability, initially measured at the present value of future lease payments, on the balance sheet and expands disclosure requirements regarding leasing arrangements.  The Company elected the practical expedients under ASC 842-10-65-1(f) and ASC 842-10-15-37 that allowed the Company to forego the requirement to reassess the lease classification of its existing office lease and to combine the lease and nonlease components associated with its office lease as a single lease component.  The consideration in the office lease that is allocated to the single lease component includes the fixed payments for the right to use the office space as well as common area maintenance.  The office lease also contains costs associated with certain expense escalation, property taxes, insurance, parking, and utilities which are all considered variable payments and are excluded from the operating lease liability.  The adoption of this accounting standard did not materially impact the Company’s results of operations, other than the recognition of the operating lease right-of-use asset and lease liability.  See Note 7 for further details.
