During the preparation of the condensed consolidated financial statements for the three months ended March 31, 2020, the Company identified certain immaterial errors related to its accounting of the 2019 Lincoln Park Note, 2019 Lincoln Park Warrants and the Pinnacle Note (each as defined in Note 9 – Notes Payable-Convertible Notes below), which were corrected and reflected in the Company’s first quarter, 2020 Form 10-Q. The Company concluded that the conversion feature of the 2019 Lincoln Park Note and the 2019 Lincoln Park Warrants met the definition of a derivative and should have been recorded at fair value at inception and remeasured at each reporting period with changes in the fair value recognized in earnings. The accretion to par value of the 2019 Lincoln Park Note is recorded as interest expense. The Company had originally accounted for the 2019 Lincoln Park Warrants as equity-linked instruments and had not bifurcated the conversion feature in the 2019 Lincoln Park Note.
