Operations & financial report
Financial risk management
The Group's policies with regard to financial risk management are clearly defined and consistently applied. They are a fundamental part of the Group's long term strategy covering areas such as foreign exchange risk, interest rate risk, commodity price risk, credit risk and liquidity risk and capital management. From 1 January 2008, Rio Tinto Alcan has adopted the Rio Tinto Group policy on trading and hedging.
The Group's business is finding, mining and processing mineral resources, and not trading. Generally, the Group only sells commodities it has produced but may purchase commodities to satisfy customer contracts from time to time and to balance the loading on production facilities. In the long term, natural hedges operate in a number of ways to help protect and stabilise earnings and cash flow.
The Group has a diverse portfolio of commodities and markets, which have varying responses to the economic cycle. The relationship between commodity prices and the currencies of most of the countries in which the Group operates provides further natural protection in the long term. In addition, the Group's policy of borrowing at floating US dollar interest rates helps to counteract the effect of economic and commodity price cycles. These natural hedges significantly reduce the necessity for using derivatives or other forms of synthetic hedging. Such hedging is therefore undertaken to a strictly limited degree, as described in the sections on currency, interest rate, commodity price exposure and treasury management below.
The Group's 2007 Full financial statements and disclosures show the full extent of its financial commitments including debt.
The risk factors to which the Group is subject that are thought to be of particular importance are summarised in the Risk factors section of the 2007 Annual report.
The effectiveness of internal control procedures continues to be a high priority in the Rio Tinto Group. The Boards' statement on internal control is included under Corporate governance on the Compliance Statements page.
