(2)    Other includes revenues from arrangements such as customer contract-related payments associated with volume shortfalls, royalties related to coal lease agreements, sales agency commissions, farm income and property and facility rentals.
Committed Revenue from Contracts with Customers
The Company expects to recognize revenue subsequent to June 30, 2021 of approximately $3.6 billion related to contracts with customers in which volumes and prices per ton were fixed or reasonably estimable at June 30, 2021. Approximately 46% 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 June 30, 2021 and December 31, 2020 consisted of the following:
