The international coal market has been a part of our business with indirect sales to end-users in Europe, Africa, Asia, North America and South America. Our sales into the international coal market are considered exports and are made through brokered transactions. During the years ended December 31, 2023, 2022 and 2021, export tons represented approximately 15.7%, 12.5% and 12.5% of tons sold, respectively.

Because title to our export shipments typically transfers to our brokerage customers at a point that does not necessarily reflect the end-usage point, we attribute export tons to the country with the end-usage point, if known. No individual country was attributed greater than 10% of total domestic and export tons sold during the years ended December 31, 2023, 2022 and 2021.

We have significant long-term coal supply agreements, some of which contain prospective price adjustment provisions designed to reflect changes in market conditions, labor and other production costs and, in the infrequent circumstance when the coal is sold other than free on board the mine, changes in transportation rates. A major customer is defined as a customer from which we derive at least ten percent of our total revenues, including transportation revenues. Total revenues from major customers are as follows:

Customer A	Illinois Basin/Appalachia	$	332,500	$	—	$	—

Customer C	Illinois Basin		—		328,406		239,482
Customer D	Illinois Basin/Appalachia		—		228,480		—

Trade accounts receivable from major customers totaled approximately $54.3 million and $63.6 million at December 31, 2023 and 2022, respectively. Our credit loss experience has historically been insignificant. Financial conditions of our customers could result in a material change to our credit loss expense in future periods. The coal supply agreements with Customers A and B expire in 2025 and 2029, respectively.
