ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Commodity Price Risk
We are exposed to commodity price risk on sales of steelmaking coal. We sell most of our steelmaking coal under fixed supply contracts primarily with indexed pricing terms and volume terms of up to one to three years. Sales commitments in the steelmaking coal market are typically not long-term in nature, and we are, therefore, subject to fluctuations in market pricing.
We occasionally enter into natural gas swap contracts to hedge the exposure to variability in expected future cash flows associated with the fluctuations in the price of natural gas related to our forecasted sales. Our natural gas swap contracts economically hedge certain risk 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 Condensed Statements of Operations. Historically, all of our derivative instruments were entered into for hedging purposes rather than speculative trading. As of March 31, 2023, the Company had natural gas swap contracts outstanding covering 4,145,000 million metric British thermal units.
We have exposure to price risk for supplies that are used directly or indirectly in the normal course of production, such as diesel fuel, steel, explosives and other items. We manage our risk for these items through strategic sourcing contracts in normal quantities with our suppliers. We historically have not entered into any derivative commodity instruments to manage the exposure to changing price risk for supplies.
Credit Risk
Financial instruments that potentially subject us to a concentration of credit risk consist principally of trade receivables. We provide our products to customers based on an evaluation of the financial condition of our customers. In some instances, we require letters of credit, cash collateral or prepayments from our customers on or before shipment to mitigate the risk of loss. Exposure to losses on receivables is principally dependent on each customer’s financial condition. We monitor the exposure to credit losses and maintain allowances for anticipated losses. As of March 31, 2023 and December 31, 2022, the estimated allowance for credit losses was immaterial and did not have a material impact on the Company's financial statements.

Interest Rate Risk
We are exposed to market risk from changes in interest rates. Our Notes have a fixed rate of interest of 7.875% per annum and are payable semi-annually in arrears on June 1 and December 1 of each year.
Our ABL Facility bears an interest rate equal to SOFR, plus a credit adjustment spread, ranging currently from 11 bps to 43 bps, or an alternate base rate plus an applicable margin, which is determined based on the average availability of the commitments under the ABL Facility, ranging currently from 150 bps to 200 bps or 50 bps to 100 bps, respectively. Any debt that we incur under the ABL Facility will expose us to interest rate risk. If interest rates increase significantly in the future, our exposure to interest rate risk will increase. As of March 31, 2023, assuming we had $132.0 million outstanding under our ABL Facility, a 100-basis point increase or decrease in interest rates would increase or decrease our annual interest expense under the ABL Facility by approximately $1.3 million.
Impact of Inflation
We have exposure to inflation for supplies that are used directly or indirectly in the normal course of production, such as belt structure, roof bolts, cable, magnetite, rock dust and other supplies, plus labor and parts on repair and rebuild equipment. These inflationary pressures have contributed to rising costs for us and may continue to do so in the future. We are applying a number of different strategies to mitigate the impact of inflation on our operations, including placing purchase orders earlier, utilizing short-term contracts and leveraging our supplier relationships.
