(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 control is transferred. Rio Tinto is domiciled in both the UK and Australia.
(b) | The 2018 and 2017 comparatives have been amended to correct the allocation of sales revenue by destination. This resulted in an increase in sales to the United States of America (2018: US$59 million, decrease in 2017: US$11 million); and to Europe (excluding UK) (2018: US$82 million; 2017: US$125 million) with a corresponding decrease in sales to the UK (2018: US$122 million, 2017: US$124 million), Canada (2018: US$10 million, increase in 2017: US$3 million) and Other countries (2018: US$9 million, increase in 2017: US$7 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. In 2017 there was no equivalent requirement under IAS 18 to separate out such provisional price movements and therefore this was not disclosed.
(b) | The 2018 and 2017 comparatives have been amended to correct the allocation of sales revenue by product. The most significant impacts are a decrease in Other product revenues (2018: US$75 million, 2017: US$25 million) and an increase in Industrial minerals revenues (2018: US$75 million, 2017: US$25 million).
