The Company records the fair value of the conversion feature of the convertible debenture disclosed in Note 11 in accordance with ASC 815. The fair value of the derivative liability was calculated using a binomial option pricing model.

During the three and nine-month periods ended December 31, 2019, the Company recorded a gain (loss) on the change in fair value of derivative liability of $57,520, and ($13,887) (December 31, 2018- ($118,236) and ($299,102)). As at December 31, 2019, the Company recorded a derivative liability of $445,473 (March 31, 2019 - $431,586).
