Note 6 - Derivative Liability

In June 2015, we granted warrants to purchase 959,924 shares of the Company’s common stock through a private offering of units (“Units”). Each Unit included one share of Common Stock, par value $0.0001 per share, and a three-year Warrant to purchase one share of Common Stock at an initial exercise price per share equal to $0.75, subject to adjustment for certain corporate transactions such as a merger, stock-split or stock dividend and, if the Company does not continue to be a reporting company under the Securities Exchange Act of 1934 during the two-year period after closing, the exercise price will be reduced to $0.01 per share. Each Unit includes limited registration rights for the investors for the shares of Common Stock and the shares of Common Stock that would be issued upon the exercise of a Warrant ("Underlying Shares") when and if we register our shares of Common Stock in a different offering, subject to certain excluded registered offerings. The Company has also issued to the placement agent warrants to purchase our shares of Common Stock equal to 10% of the total shares sold in the offering, or 95,992 shares.

Because these warrants have full reset adjustments that would preclude the instrument from being considered as index to the Company’s stock, it is subject to derivative liability treatment under ASC 815-40-15, which requires as of the date the warrants are issued, the derivative liability to be measured at fair value and re-evaluated at the end of each reporting period.

Key assumptions used to determine the fair value of the warrants follows:

As of September 30, 2017 and December 31, 2016, the fair value of the total warrants' derivative liability is $11,811 and $108,809, respectively, and recorded in other accrued expenses in the Condensed Consolidated Balance Sheets. We recognized a gain on the derivative liability of $9,573 and $2,133 for the three months ended September 30, 2017 and 2016, respectively, and $96,998 and $4,956 for the nine months ended September 30, 2017 and 2016, respectively. We record gain and loss on the derivative liability in other income, net in the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss).
