There are three categories of sales:
1) “External sales”: mined product sold to third parties at market price;
2) “Market-priced tonnes”: internal sales of mined product to ArcelorMittal facilities and reported at prevailing market prices;
3) “Cost-plus tonnes” - internal sales of mined product to ArcelorMittal facilities on a cost-plus basis. The determinant of whether internal sales are reported at market price or cost-plus is whether the raw material could practically be sold to third parties (i.e. there is a potential market for the product and logistics exist to access that market).
