NOTE 9 – 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 fair 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 $0 and $135 as of June 30, 2024, and December 31, 2023, respectively. The Company recorded gains on the change in fair value of the placement agent warrants of $13 and $1,900 during the three months ended June 30, 2024, and 2023, respectively, and $135 and $2,319 during the six months ended June 30, 2024, and 2023, 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 $0 and $333 as of June 30, 2024, and December 31, 2023, respectively. The Company recorded gains on the change in fair value of the placement agent warrants of $57 and $2,435 during the three months ended June 30, 2024, and 2023, respectively, and $333 and $2,770 during the six months ended June 30, 2024, and 2023, 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 $8 and $908 as of June 30, 2024, and December 31, 2023, respectively. The Company recorded gains on the change in fair value of the placement agent warrants of $289 and $2,973 during the three months ended June 30, 2024, and 2023, respectively, and $900 and $3,172 during the six months ended June 30, 2024, and 2023, respectively.
