Subsequent Events The Company has evaluated the impacts of subsequent events through May 17, 2019, and has determined that no such events occurred that were required to be reflected in the unaudited condensed consolidated financial statements, except as described within the above notes and described below.

In exchange for the amendment, the Company compensated the holder of the note by increasing the outstanding principal due by $50. On May 10, 2019, the two holders of the May 2018 Notes assigned and sold all notes to a single unaffiliated investor. On the same date, the Company and new investor executed a letter agreement to amend the terms of the May 2018 Notes to allow the new investor to convert the total outstanding principal amount of $421 into shares of the Company’s common stock, at a price equal to 70% of the lowest trading price during the 20 days preceding the conversion dates, or any lower price made available to any other holder of the Company’s securities. This amendment also eliminates the Company’s mandatory monthly amortization payments and extended the maturity of the May 2018 Notes until August 15, 2019. After such date, and within 10 business days, any outstanding balance shall be satisfied, at the Company’s election, either with: cash, common stock conversion or any combination thereof.
