Revenue from Contract with Customer [Text Block]	( 6 REVENUE Revenue from Contracts with Customers We account for a contract with a customer when the parties have approved the contract and are committed to performing their respective obligations, the rights of each party are identified, payment terms are identified, the contract has commercial substance, and it is probable substantially all of the consideration will be collected. We recognize revenue when we satisfy a performance obligation by transferring control of a good or service to a customer. Coal operations Our coal revenue is derived from sales to customers of coal produced at our facilities. Our customers typically purchase coal directly from our mine sites or our rail facility in Princeton, Indiana, where the sale occurs and where title, risk of loss, and control pass to the customer at that point. Our customers arrange for and bear the costs of transporting their coal from our mines to their plants or other specified discharge points. Our customers are typically domestic utility companies. Our coal sales agreements with our customers are fixed-priced, fixed-volume supply contracts or include a pre-determined escalation in price for each year. Price re-opener and index provisions may may Coal sales agreements will typically contain coal quality specifications. With coal quality specifications in place, the raw coal sold by us to the customer at the delivery point must be substantially free of magnetic material and other foreign material impurities and crushed to a maximum size as set forth in the respective coal sales agreement. Price adjustments are made and billed in the month the coal sale was recognized based on quality standards that are specified in the coal sales agreement, such as Btu factor, moisture, ash, and sulfur content, and can result in either increases or decreases in the value of the coal shipped. Electric operations The Company concluded that the definition of a contract and the criteria in ASC 606, 606" 606. The Company will recognize revenue daily for the actual capacity made available as part of any stand-ready obligations to provide electricity for contract capacity performance obligations and daily for actual delivered electricity, plus the amortization of the contract liability as a result of the Asset Purchase Agreement with Hoosier, for the delivered energy performance obligation. Disaggregation of Revenue Revenue is disaggregated by primary geographic markets, as we believe this best depicts how the nature, amount, timing, and uncertainty of our revenue and cash flows are affected by economic factors. Coal operations 52% March 31, 2023, 2022, Electric operations 100% of our electric revenue for the quarter ended March 31, 2023, Performance Obligations Coal operations A performance obligation is a promise in a contract with a customer to provide distinct goods or services. Performance obligations are the unit of account for purposes of applying the revenue recognition standard and therefore determine when and how revenue is recognized. In most of our coal contracts, the customer contracts with us to provide coal that meets certain quality criteria. We consider each ton of coal a separate performance obligation and allocate the transaction price based on the base price per the contract, increased or decreased, for quality adjustments. We recognize revenue at a point in time as the customer does not We have remaining coal sales performance obligations relating to fixed-priced contracts of approximately $511 million, which represent the average fixed prices on our committed contracts as of March 31, 2023. 65% 2023, We have remaining performance obligations relating to unpriced coal sales contracts of approximately $166 million, which represents our estimate of the expected price on committed contracts as of March 31, 2023. 2024 The coal tons used to determine the remaining performance obligations are subject to adjustment in instances of force majeure and exercise of customer options to either take additional tons or reduce tonnage if such option exists in the customer contract. Electric operations The Company concluded that each megawatt-hour ("MWh") of delivered energy is capable of being distinct as a customer could benefit from each on its own by using/consuming it as a part of its operations. The Company also concluded that the stand-ready obligation to be available to provide electricity to Hoosier is capable of being distinct as each unit of capacity provides an economic benefit to the holder and could be sold by the customer. We have remaining delivered energy obligations through 2025 March 31, 2023. In addition to delivered energy, Hallador provides stand-ready obligations to provide electricity, also known as contract capacity. We have remaining capacity obligations through 2025 totaling $100 million as of March 31, 2023. Contract Balances Under ASC 606, Under the typical payment terms of our contracts with customers, the customer pays us a base price for the coal, increased or decreased for any quality adjustments, electricity, or capacity. Amounts billed and due are recorded as trade accounts receivable and included in accounts receivable in our consolidated balance sheets.
