8. Convertible Note Derivatives

The June 2024 Convertible Note Derivative and September 2024 Convertible Note Derivative, each which relate to the June 2024 Notes and September 2024 Notes, respectively, described in Note 7-Debt, were valued upon initial recognition and at each reporting period at fair value using a with-and-without methodology utilizing a binomial lattice model (a model which utilizes Level 3 fair value inputs). The significant assumptions used in the fair value model for the Convertible Note Derivatives on certain key dates include the following, with changes in volatility, debt rate and stock price having the most significant impact on the related fair values.

Changes in the fair value between periods were recognized in Derivative gain (loss) in the statement of operations but had no related impact on the Company’s cash position or cash flows. The provision that resulted in separate accounting for the June 2024 Convertible Note Derivative began June 11, 2024 in connection with the issuance of the June 2024 Notes, and on September 16, 2024 for the September 2024 Convertible Note Derivative in connection with the issuance of the September 2024 Notes. Each of these provisions expired on December 31, 2024, and accordingly, the Convertible Note Derivatives were derecognized and the remaining fair values were transferred to additional paid-in capital on such date. Refer to Note 10-Equity for additional information. There were no other derivative instruments outstanding for any period after December 31, 2024.
