The fair value of cash, restricted cash, accounts receivable, accounts payable and accrued expenses approximates the carrying values because of the short-term nature of these instruments. The carrying value and fair value of the Credit Facility were $46,154 and $51,366 at June 30, 2023, and $45,712 and $50,293 at December 31, 2022, respectively. See Note 8 - Long-Term Debt, Net of Debt Discount and Financing Fees.
The debt derivative liabilities are measured using a ‘with and without’ valuation model to compare the fair value of each tranche of the Credit Facility including the identified embedded derivative features and the fair value of a plain vanilla note with the same terms. The fair value of the Credit Facility including the identified embedded derivative features was determined using a probability-weighted expected return model based on four potential settlement scenarios for the financing agreement as disclosed in the table below. The estimated settlement value of each scenario, which would include any required make-whole payment, (see Note 8 - Long-Term Debt, Net of Debt Discount and Financing Fees), is then discounted to present value using a discount rate that is derived based on the initial terms of the financing agreement at issuance and corroborated utilizing a synthetic credit rating analysis.
