[3] These warrants contain a full ratchet anti-dilution price protection so that, in most situations upon the issuance of any common stock or securities convertible into common stock at a price below the then-existing exercise price of the outstanding warrants, the warrant exercise price will be reset to the lower common stock sales price. As such anti-dilution price protection does not meet the specific conditions for equity classification, the Company is required to classify the fair value of these warrants as a liability, with changes in fair value to be recorded as income (loss) due to change in fair value of warrant liability. The estimated fair value of our warrant liability at September 30, 2018 and December 31, 2017, was approximately $5 and $28, respectively.
