NOTE 8 – DERIVATIVES

Certain warrants issued to placement agents were determined to be a derivative liability due to certain features of the warrants which could, in certain circumstances, result in the holder receiving the Black Scholes value of the outstanding warrants in the same type of consideration as the common stockholders. As a result, in those circumstances, the amount of consideration would differ from that provided to holders of common stock, therefore, the warrants were classified as a liability.

The fair value of the placement agent warrants issued in connection with the March 2020 private placement was determined to be $135 and $3,355 as of December 31, 2023, and December 31, 2022, respectively. The Company recorded gains on the change in fair value of the placement agent warrants of $3,220 and $37,981 during the year ended December 31, 2023, and December 31, 2022, respectively. The placement agent warrants expire in March 2025.

The fair value of the placement agent warrants issued in connection with the May 2020 offering of securities was determined to be $333 and $4,479 as of December 31, 2023, and December 31, 2022, respectively. The Company recorded gains on the change in fair value of the placement agent warrants of $4,146 and $38,167 during the year ended December 31, 2023, and December 31, 2022, respectively. The placement agent warrants expire in May 2025.

The placement agent warrants issued in connection with the June 2020 warrant exercise and issuance had a fair value of $908 and $5,999 as of December 31, 2023, and December 31, 2022, respectively. The Company recorded gains on the change in fair value of the placement agent warrants of $5,091 and $39,499 during the year ended December 31, 2023, and December 31, 2022, respectively.
