The embedded conversion option was expensed along with the remaining unamortized discount at the date of the Bridge Financing Notes repayment. The warrants issued to jVen Capital and MGHIF are classified as mark-to-market liabilities under ASC 480 due to certain put features that allow the holder to put the warrant back to the Company for cash equal to the Black-Scholes value of the warrant upon a change of control or fundamental transaction. Total interest expense (including amortization of debt discounts and financing fees) on all debt instruments was $233,505 and $143,347 for the years ended December 31, 2017 and 2016, respectively.
