[1] | The fair value of the Partnership's contract receivable is determined based on the present value of future cash flow projections related to the underlying asset at a discount rate of 15% at June 30, 2023 and December 31, 2022.
[2] | The fair value of the Opco Senior Notes at June 30, 2023 and December 31, 2022 were estimated by management utilizing the present value replacement method incorporating the interest rate of the Opco Credit facility at June 30, 2023 and December 31, 2022, respectively.
[3] | The fair value of the Opco Credit Facility approximates the outstanding borrowing amount because the interest rates are variable and reflective of market rates and the terms of the credit facility allow the Partnership to repay the debt at any time without penalty.
