Disaggregation of Revenue

Revenue by product type and market is set forth in the following tables. With respect to its seaborne reporting segments, the Company classifies as “Export” certain revenue from domestically-delivered coal under contracts in which the price is derived on a basis similar to export contracts.

Primarily represents the difference between the price contracted with the customer and the price allocated to the operating segment.

Committed Revenue from Contracts with Customers

The Company expects to recognize revenue subsequent to December 31, 2022 of approximately $6.3 billion related to contracts with customers in which volumes and prices per ton were fixed or reasonably estimable at December 31, 2022. Approximately 40% of such amount is expected to be recognized over the next twelve months and the remainder thereafter. Actual revenue related to such contracts may differ materially for various reasons, including price adjustment features for coal quality and cost escalations, volume optionality provisions and potential force majeure events. This estimate of future revenue does not include any revenue related to contracts with variable prices per ton that cannot be reasonably estimated, such as the majority of seaborne metallurgical and seaborne thermal coal contracts where pricing is negotiated or settled quarterly or annually.

Accounts Receivable

“Accounts receivable, net” at December 31, 2022 and 2021 consisted of the following:

	December 31,
	2022		2021
	(Dollars in millions)
Trade receivables, net	$	416.3	$	307.0
Miscellaneous receivables, net	49.2		43.5
Accounts receivable, net	$	465.5	$	350.5

None of the above receivables included allowances for credit losses at December 31, 2022 or 2021. No charges for credit losses were recognized during the years ended December 31, 2022, 2021 or 2020.
