Fair Value Disclosures [Abstract] |
Fair Value Measurements, Policy | FAIR VALUE MEASUREMENTS The Company utilizes the income approach to measure fair value for its commodity derivatives using Level 2 inputs. The income approach uses pricing models that rely on market observable inputs such as yield curves and forward prices. Refer to Note 11 for the classification of changes in fair value of derivative assets and liabilities measured at fair value on a recurring basis within the Consolidated Statements of Operations. The Company’s financial assets and liabilities also include cash, cash equivalents and restricted cash, receivables and accounts payable for which the carrying value approximates fair value due to their short maturities (less than 12 months). The Company does not record its long-term debt at fair value on the Consolidated Balance Sheets. The fair value of any outstanding borrowings under the Revolving Credit Facility (as defined in Note 13) approximated its carrying value. Based on market rates, the fair value (Level 2) of the Company’s debt, excluding any borrowings under the Revolving Credit Facility, was $869.0 and $880.6 as of September 30, 2025 and 2024, respectively. Certain assets and liabilities, including property, goodwill and other intangible assets, are measured at fair value on a non-recurring basis using Level 3 inputs. No impairment charges were recorded for property, goodwill or other intangible assets during the years ended September 30, 2025, 2024 or 2023.
