Dividend policy

The Group expects that the total cash dividend payment for the 2010 financial year will be at least equal to that paid for 2008 (US$1.75 billion), albeit over an increased number of shares. The Group remains committed to a progressive dividend policy over the longer term.

Dividend determination

The majority of the Group's sales are transacted in US dollars, making this the most reliable measure for the Group's global business performance. It is Rio Tinto's main reporting currency and consequently the natural currency for dividend determination. Dividends determined in US dollars are translated at exchange rates prevailing two days prior to the announcement and are then declared payable in sterling by Rio Tinto plc and in Australian dollars by Rio Tinto Limited.

On request, shareholders of Rio Tinto plc can elect to receive dividends in Australian dollars, and Rio Tinto Limited shareholders can elect to receive dividends in Australian dollars. The dividend amounts received will be calculated by converting the declared dividend using the exchange rates applicable to pounds sterling and Australian dollars five days prior to the dividend payment date.  Shareholders requiring further information should contact Computershare.

Holders of American Depositary Shares are paid in US dollars, which will be converted from pounds sterling by reference to the exchange rate applicable five days prior to the payment date.
