4. DERIVATIVE INSTRUMENTS

Natural gas derivatives

As of December 31, 2024 and 2023 the Company held a series of call options (the "Call Options”) for the purchase of natural gas related to customer commitments. The Call Options are for a total of 0.3 million MMBtu (million British thermal units) of natural gas at December 31, 2024, and extend into the second quarter of 2025. The Company purchased the Call Options to manage the risk of increasing natural gas prices above what it can charge its customers. The Company may also enter into other derivative transactions when beneficial. The Company recognizes all of its derivative instruments as either assets or liabilities which are recorded at fair value on its Consolidated Balance Sheet. The fair value of the Call Options are predominantly determined from broker quotes and are considered a level 2 fair value measurement. The following table presents the location and fair value of the Call Options at December 31, 2024 and 2023 (in thousands):
