REVENUE. | NOTE 11—REVENUES Our revenue is derived from contracts for the sale of coal and is recognized when the performance obligations under the contracts are satisfied, which is at the point in time control is transferred to our customer. Generally, domestic sales contracts have terms of about one year and the pricing is typically fixed. Export sales have spot or term contracts, and pricing can be either a fixed price or a price derived against index-based pricing mechanisms. Sales completed with delivery to an export terminal are reported as export revenue. Disaggregated information about our revenue is presented below: ​

​ Fourth quarter 2022 revenue that can be derived from the Company’s periodic filings includes a $2.8 million downward adjustment to revenue related to performance obligations that were satisfied in the previous quarter. This adjustment was due to the true-up of the Company’s previous estimate of certain provisional pricing provisions. As of December 31, 2022, the Company had outstanding performance obligations of approximately 1.5 million tons for contracts with fixed sales prices averaging $202 per ton, excluding freight, which will generally be satisfied within the next year, and 0.7 million tons for contracts with index-based pricing mechanisms. Index-based prices have not been estimated for the purpose of disclosing remaining performance obligations as permitted under the revenue recognition guidance when variable consideration is allocated entirely to a wholly unsatisfied performance obligation. Sales into individual foreign countries equaling or exceeding 10% of our total revenues included Canada and South Africa at 12% and 10%, respectively, for 2022.
