10. Fair Value Measurements

Our financial instruments consist of cash, accounts payable, accrued liabilities, and warrant liability. We do not believe that we are exposed to significant interest, currency, or credit risks arising from these financial instruments. The fair values of the warrants approximates their carrying values using Level 3 inputs. Gains and losses recognized on changes in fair value of the warrants are reported in other income (expense). Our warrant valuation was measured at fair value by applying the Black-Scholes option valuation model, which utilizes Level 3 inputs.

The assumptions used in the Black-Scholes option re-valuation at March 31, 2019 are as follows:

 

  Risk-free interest rate Expected life Volatility Dividend yield
September 2016 warrants 2.21% 2.50 years 230.000% 0%
March 2017 warrants 2.21% 3.50 years 238.947% 0%
March 6, 2018 warrants 2.23% 4.50 years 218.564% 0%
March 16, 2018 warrants 2.27% 2.00 years 266.095% 0%
August 2018 warrants 2.23% 5.00 years 213.512% 0%
