The Company enters into natural gas swap contracts from time to time to hedge the exposure to variability in expected
future cash flows associated with the fluctuations in the price of natural gas related to the Company’s forecasted sales. As of December 31, 2024, the company had 5,500,000 metric million British thermal unit gas contracts outstanding. As of December 31, 2023, there were no such natural gas swap contracts outstanding.

The Company’s natural gas swap contracts economically hedge certain risks but are not designated as hedges for
financial reporting purposes. All changes in the fair value of these derivative instruments are recorded as other revenues in the
Statements of Operations. The Company had an unrealized loss of $1.8 million for the year ended December 31, 2024 and recognized a loss of $1.2 million for the year ended and December 31, 2023.
