Note 7 - Change On Accounting Method |
Change on Accounting Method | Adoption of ASU 2017-11 In connection with the securities purchase agreements and debt transactions during the year ended December 31, 2017, the Company issued warrants, to purchase common stock with a five-year term. Upon issuance of the warrants, the Company evaluated the note agreement to determine if the agreement contained any embedded components that would qualify the agreement as a derivative. The Company identified certain put features embedded in the warrants that potentially could result in a net cash settlement in the event of a fundamental transaction, requiring the Company to classify the warrants as a derivative liability. The Company changed its method of accounting for the debt and warrants through the early adoption of ASU 2017-11 on January 1, 2018 on a retrospective basis. Accordingly, the Company recorded the warrant derivative and conversion option derivative liabilities to additional paid in capital upon issuance. The following table provides a summary of the derivative liability activity as a result of the adoption of ASU 2017-11 (in thousands, except per share data):
