The Company elected to fair value the convertible notes payable issued under the 2021 and 2022 Convertible Loan Note Instruments. At the end of each reporting period, the Company calculated the fair value of the convertible notes payable, and any changes in fair value are reported in other income (expense), net, in the current period’s unaudited condensed consolidated statements of operations and Comprehensive Loss. There has been no change in fair value from a change in credit quality.

The note contains a conversion option which allows the holder of the note to convert the principal, plus any accrued interest at the date of conversion, into shares of CDT common stock at a conversion price of $10. The note carries 20% interest, which is payable every six (6) months from the date of the note until the maturity date. The promissory convertible note payable was not converted at the closing of the Merger and was also not converted as of March 31, 2024. The Company has not elected the fair value option and will account for the promissory convertible note payable as a liability in accordance with ASC 480 on the Company’s balance sheet. The only subsequent measurement impact on a recurring basis until conversion (if conversion occurs) or prepayment (if prepayment occurs) will be to record the accrued interest as a liability and reduce the balances of the Note and its accrued interest for cash payments made against these balances. For the three months ended March 31, 2024 and March 31, 2023, interest on the convertible promissory note totaled forty thousand dollars and forty thousand dollars, respectively.
