Fair Value Disclosures [Abstract] |
Schedule Of Carrying And Fair Values Of Long-Term Debt | The carrying and fair values of the Partnership's long-term debt at December 31, 2025 and December 31, 2024 are summarized in the table below. The fair value of long-term debt is determined based on the present value of expected future cash flows using a discounted cash flow methodology. Because the Partnership's valuation methodology used for long-term debt requires the use of significant unobservable inputs, the inputs used to measure the fair value of the Partnership's long-term debt are classified as Level 3 within the fair value hierarchy. Inputs used to estimate the fair values of the Partnership's long-term debt include the selection of an appropriate discount rate.
