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 $13 and $135 as of March 31, 2024, and December 31, 2023, respectively. The Company recorded gains on the change in fair value of the placement agent warrants of $122 and $419 during the three months ended March 31, 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 $58 and $333 as of March 31, 2024, and December 31, 2023, respectively. The Company recorded gains on the change in fair value of the placement agent warrants of $275 and $335 during the three months ended March 31, 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 $296 and $908 as of March 31, 2024, and December 31, 2023, respectively. The Company recorded gains on the change in fair value of the placement agent warrants of $612 and $199 during the three months ended March 31, 2024, and 2023, respectively. The placement agent warrants expire in June 2025.
