Material Changes vs. Prior Period
Revenue and Earnings Drivers:
- Commodity Prices: Most commodity prices increased in the second half of 2016. Iron ore average realized price rose ~2% to US$49.3/tonne. However, lower prices for copper (-11%) and aluminium (-3%) offset gains, resulting in a net negative price variance of US$460 million on underlying earnings.
- Cost Reduction: The company delivered US$1.6 billion in pre-tax operating cash cost savings and reduced exploration expenditure, contributing US$1.124 billion to underlying earnings.
- Volume: Sales volumes increased earnings by US$19 million, driven by iron ore and bauxite, partially offset by lower copper and gold volumes.
Significant One-Off Items (Excluded from Underlying Earnings):
- Impairment Charges: US$183 million (primarily Argyle diamond mine).
- Disposals: Net gain of US$382 million (sale of Bengalla JV and Lochaber assets).
- Onerous Contracts: US$329 million charge related to relinquishing Abbot Point Coal Terminal capacity.
- Exchange Differences: US$536 million gain on intragroup balances and external debt.
Outlook, Risks, and Management Commentary
Management Commentary:
Management highlighted that market uncertainties were greater than planned, with upside movement in commodity prices and demand. The balance sheet strengthened significantly due to greater-than-planned cash flow. The company continues to focus on cost reduction and capital discipline.
Risk Factors:
- Increasing Risks: Commodity prices, China's development pathway, strategic partnerships, jurisdictional risk, and regulation.
- Decreasing Risks: Liquidity risk has decreased due to a stronger balance sheet.
- Operational Risks: Health, safety, environment, and community (HSEC) risks remain critical, including tailings facilities and pit slope stability.
- Geopolitical: Increased uncertainty regarding joint venture operations and resource nationalism.
Capital Projects:
Major projects in 2016 included the Oyu Tolgoi copper/gold underground mine, Amrun bauxite infrastructure, and Silvergrass iron ore mine. Capital expenditure (Capex) declined 36% to US$3.0 billion compared to 2015.
Investor Verification Checklist
- Dividend Sustainability: Verify the ability to maintain the 170 US cents total dividend given the volatility in commodity prices and the reduction in interim dividends compared to 2015.
- Debt Maturity Profile: Review the maturity schedule of the US$18.0 billion in adjusted total borrowings, noting that 80% are at floating rates.
- Impairment Triggers: Monitor the Argyle diamond mine and other assets for further impairment risks if diamond or copper prices decline.
- China Exposure: Assess the impact of China's economic development pathway on iron ore and coal demand.
- Joint Venture Governance: Review the status of the Simandou project in Guinea and other joint ventures where Rio Tinto does not have full managerial control.
