If the eventual destination of the product sold through traders is not known then revenue is allocated to the location of the product at the time when control is transferred.

(a)Certain of the Group’s products may be provisionally priced at the date revenue is recognised based on forward rates. The subsequent changes in value of provisionally priced receivables through to settlement is classified as ‘Other revenue’ above. (b)The 30 June 2019 comparatives have been amended to correct the allocation of sales revenue by product. The most significant impacts are an increase in Other product revenues of US$37 million and a decrease in Iron ore revenues of US$37 million. For 30 June 2020 Uranium product sales have been separately presented from Other revenues along with the comparative. This was following consideration of the materiality of the Other category.
