Guidance, Outlook, Risks, and Unusual Items
Management Commentary and Outlook
Management expects an effective tax rate on underlying earnings of approximately 30% in 2018. The Group continues to focus on a "value-over-volume" strategy, returning cash to shareholders, strengthening the balance sheet, and investing in high-quality green and brownfield projects. A mine-to-market productivity program is targeting an additional US$5.0 billion in free cash flow from 2017 to 2021.
Risks and Contingencies
- Market Risks: Exposure to falling commodity prices and adverse exchange rate movements. China remains the dominant market for the Group's products.
- Operational Risks: Hazards include pit slope instability, tailings facilities, and cyber security threats. A strike at the Escondida mine in early 2017 impacted volumes and costs.
- Geopolitical Risks: Sovereign risk and geopolitical uncertainty remain elevated. The Group maintains a passive minority shareholding in Rössing Uranium Limited (Namibia) held by the Iranian Foreign Investments Company (IFIC), which is subject to US sanctions; however, Rio Tinto has no control over IFIC's holdings.
Unusual Items
- Impairments: US$481 million in impairment charges were recognized, primarily related to the Roughrider uranium deposit, Rössing uranium mine, and Argyle diamond mine.
- Insurance Settlement: The Group received a final insurance settlement of US$233 million (pre-tax) related to the 2013 Kennecott pit-wall slide.
- Tax Changes: Deferred tax assets were remeasured due to corporate tax rate changes in the US and France.
Investor Verification Checklist
- Verify the sustainability of the 20% increase in iron ore prices and the impact of China's economic growth pathway on future demand.
- Review the details of the US$2.5 billion bond redemption and the remaining maturity profile of the US$15.4 billion in total financing liabilities.
- Assess the impact of the US$481 million impairment charges on the carrying values of the Roughrider, Rössing, and Argyle assets.
- Monitor the progress of the mine-to-market productivity program and its ability to deliver the targeted US$5.0 billion in additional free cash flow.
- Confirm the status of the Escondida strike resolution and its long-term impact on Copper & Diamonds segment performance.
- Review the specific terms and risks associated with the passive minority shareholding of IFIC in Rössing Uranium Limited regarding US sanctions compliance.
