The financial information by business unit and the geographic analysis of sales by destination satisfy the disclosure requirements of IFRS 8 ‘Operating Segments’ for interim financial statements and also provide additional voluntary disclosure which the Group considers is useful to the users of the financial statements.


(a)	Consolidated sales revenue by geographical destination is based on the ultimate country of destination of the product, if known. 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 the risks and rewards of ownership are transferred. Rio Tinto is domiciled in both the UK and Australia.


(b)	The 30 June 2018 comparatives have been amended to correct the allocation of sales revenue by destination. This resulted in a decrease in sales to the United States of America and the UK by US$59 million and US$56 million respectively with a corresponding increase in sales to Europe (excluding UK) of US$45 million, Canada of US$37 million and Other countries of US$33 million.

(a)	Certain of the Group’s products may be provisionally priced at the date revenue is recognised. The change in value of the provisionally priced receivables is based on relevant forward market prices and is included in ‘Other revenue’ above.


(b)	The 30 June 2018 comparatives have been amended to correct the allocation of sales revenue by product. The most significant impacts are an increase in Other products revenues of US$39 million and a decrease in Iron ore revenues of US$36 million.
