Key Financial Metrics (2005)

Note: Net debt reduced by $2,496 million during the year. The Group operating profit margin improved significantly due to higher commodity prices and volumes.

Material Changes vs. Prior Period

• Revenue Growth: Consolidated turnover increased by 47% to $19.0 billion, driven by a 71.5% increase in iron ore benchmark prices, a 28% increase in copper prices, and higher volumes across most product groups.
• Profit Surge: Net earnings rose 58% to $5.2 billion. Underlying earnings more than doubled, increasing by 118% to $4.95 billion.
• Price and Volume Drivers: Price movements contributed $2.37 billion to earnings, while volume increases contributed $1.14 billion. Higher costs reduced earnings by $598 million, primarily due to energy, labor, and equipment shortages.
• Asset Disposals: The Group sold its 14.5% interest in Lihir Gold for $295 million and its interest in the Labrador Iron Ore Royalty Income Fund for $130 million. Net profit on disposals was $311 million (compared to $1.175 billion in 2004).
• Balance Sheet Strengthening: Net debt fell to $1.3 billion (8% of total capital) from $3.8 billion, supported by record cash flows and debt repayments of $807 million.

Guidance, Outlook, and Management Commentary

• Market Outlook: Management expects strong short-term demand to continue into 2006, with supply/demand balances remaining tight and prices tracking above long-term trends. However, the Group acknowledges the cyclical nature of the industry and the inevitability of a future downturn.
• Capital Management: A new capital return program was announced totaling $4.0 billion, comprising a $1.5 billion special dividend and a $2.5 billion share buyback program to be completed by the end of 2007.
• Investment Strategy: The Group invested $2.5 billion in 2005 and expects to spend an additional $3 billion in both 2006 and 2007. Major projects include the expansion of iron ore capacity in the Pilbara (Western Australia), the QMM titanium project in Madagascar, and the Cortez Hills gold project in Nevada.
• Risks: Key risks include commodity price volatility, exchange rate fluctuations (particularly the strengthening of the Australian and Canadian dollars against the US dollar), rising input costs (energy, labor, equipment), and political instability in operating jurisdictions.

Important Facts for Investor Verification

• Commodity Price Sensitivity: Verify the Group's exposure to specific commodity prices; a 10% change in copper prices impacts net earnings by approximately $215 million, and aluminium by $114 million.
• Reserve Estimates: Ore reserves are estimated based on a three-year average historical price to June 30, 2005. Verify if current market prices significantly deviate from these assumptions, which could impact future reserve reporting and asset valuations.
• Debt Maturity Profile: Approximately $1.19 billion (31%) of borrowings mature in 2006. Verify the Group's liquidity position and access to credit facilities to manage this maturity wall.
• Share Buyback Execution: Monitor the execution of the $2.5 billion buyback program announced in February 2006, which is subject to market conditions.
• Regulatory Approvals: Verify the status of regulatory approvals for major projects, specifically the Hope Downs iron ore joint venture and the Madagascar titanium project, which are critical to future growth.
