| Carrying Amounts and Fair Values of Financial Instruments | The following presents the carrying amounts and the fair values and hierarchy of our financial instruments as of June 30, 2026 and December 31, 2025 (in thousands):
(a) Fair values for commodity derivatives utilize Level 2 inputs with the exception of swaptions and propane collars, which utilize Level 3 inputs. Fair value of swaption contracts as of June 30, 2026 was a derivative liability of $657,000 and the fair value of propane collars as of June 30, 2026 was a derivative asset of $882,000. (b) Marketable securities, which are held in our deferred compensation plans, are actively traded on major exchanges, which is a Level 1 input. (c) The book value of our bank debt approximates fair value because of its floating rate structure. The fair value of our senior notes is based on end of period market quotes which are Level 2 inputs. Debt is presented on the balance sheet at carrying value. (d)
The fair value of our deferred compensation plan is updated to the closing price of the marketable securities held in the plan on the balance sheet date, which is a Level 1 input. |
