[1] The Company had warrants that triggered the required issuance of an additional 2,023,438 warrants as a result of the Company's capital raise that gave those new investors a $0.40 per share investment price which required the old warrant holders to receive additional warrants since their price was $0.75 per share.
[2] The Company had estimated on April 17, 2020 that the number of warrants to be granted for the bridge financing would be 354,836,286. The bridge financing closed on September 11, 2020 in which an additional 8,310,479 warrants were issued above the original estimate for a total of 363,146,765. The fair market value associated with the additional warrants issued was recorded to the change in fair value of derivative liability - warrants prior to being reclassed to equity.
