Derivative Liability

The table below provides a summary of the changes in fair value of the derivative liabilities related to Convertible notes using significant unobservable inputs (level 3):

The Embedded Put Features were separately measured at fair value, with changes in fair value recognized in current operations. The scenario-based analysis estimates the fair value of the Convertible Notes based on the probability-weighted present value of expected future investment returns, considering each of the possible outcomes available to the holders, including various settlement, equity financing, and corporate transaction and dissolution scenarios. Estimating fair values of Embedded Put Features required the development of significant and subjective estimates that changed over the duration of the instrument with related changes in internal and external market factors. Because the Embedded Put Features are initially and subsequently carried at fair values, the Company’s income reflected the volatility in these estimate and assumption changes.
