Emerging risks
As we enter a year where externalnew era of complexity, we expect to experience increasing uncertainty continuedfrom the interplay of three global forces; geopolitics, technology and internal risks required constant vigilance.

There remain significant implications for the Group that arise from ever-growing geopolitical contexttensions impacting market sentiment. Rising trade tensions between global centres of demand and supply, geopolitical frictions such as the Hong Kong crisis, and deteriorating corporate balance sheets have the potential to slow global growth and impact demand for globalour products. This in turn could affect Group earnings. Additionally, as not all societies have benefited equally from globalisation, there is an increasing focus on resource nationalism. Global economic conditions remained uncertain throughout 2019 due to escalated trade remained unsettled. However, markets in general continued to grow.tensions and heightened geopolitical instability. This combination drove a focus on external factorscreated market volatility.

Advances in technology bring both opportunities and the continuation of productivity initiativesthreats in the Group to deliver our value-over-volume strategy. Enhancements to controls for managing operational risks (particularly cyber securitymedium term. Digital connectivity, and major hazards) sought to maintain and build resilience.

As stronger prices flowed through and supply was delivered in line with expectations, Rio Tinto retained its strong capital allocation discipline, returning cash to shareholders, further strengthening the balance sheet and investing in high quality long term green and brownfield projects.  

Principal joint operations, managed and non-managed, and particularly those in jurisdictions with higher sovereign risk, continue to require close monitoring and active management.  

Changes to the risk profile of the Group during 2017 are illustrated in the summary table below. Further detail on movements and monitoring of these exposures is provided in the relevant section of the Strategic report, including Market environment, Group strategy, product group overviews, the Directors’ report and the Notes to financial statements of the Annual Report 2017.

Emerging risks

Looking ahead, the external risk landscape continues to evolve. In the relatively near term, increased protectionism and geopolitical uncertainty present risk and uncertainty to the operating environment. In the medium term, technological disruption – from increased automation in mining and processing to greater use of cognitive learningintelligent systems supported by advanced analytics and artificial intelligence, – provides both threats and opportunities as companies seekare expected to secure competitive advantage. drive the fourth stage of industrialisation. We are acutely aware that with increasing reliance on technology comes a necessity to continue to enhance our cyber security.


In the longer term, we see societal expectations around the societal imperativeimpact of our business on the local economy, communities and environment continuing to manage areas ofrise. There has also been an increase in focus by investment firms on environmental, risk is expected to increase at the macro level, as concern about the ineffective management of “global commons” – the oceans, atmospheresocial and climate system – drives a search for sustainable solutions.

Internally, the strengthening of the commercial capability of the Group, through the appointment of a chief commercial officer and the development of a strong governance and risk framework to support co-located commercial operations in Singapore, will ensure appropriately rigorous management of this increasingly(ESG) issues when considering their investment criteria. Climate change constitutes an important part of the business. In addition,ESG framework. Climate risks and opportunities have formed part of our strategic thinking and investment decisions for over two decades. Our climate change report explains our approach to governance and risk management in this area and sets out our 2030 targets and our ambition to reach net zero emissions by 2050 across our operations.


There remain certain threats, such as natural disasters and pandemics where there is limited capacity in the establishment of a dedicated closure team will provide stronger planninginternational insurance markets to transfer such risks.  We monitor closely such threats, and oversightdevelop business resilience plans.

Risk management framework

Rio Tinto is exposed to a variety of risks (both threats and opportunities) that can have financial, operational and compliance impacts on our business performance, reputation and licence to operate. The board recognises that creating shareholder value is the reward for taking and accepting risk. The effective management ofOur risk is therefore critical to supporting the delivery of the Group’s strategic objectives.

Rio Tinto’s risk management framework reflects this. The responsibility for identifying and managing risks lies with all of Rio Tinto’s employees and business leaders. They operate within the Group-wide framework to manage risks within approved limits.

The framework includes clearly defined oversight responsibilities for the board and the Executive Committee, who are supported by the Risk Management Committee and central support functions including Group Risk and Group Internal Audit, to enable effective risk identification, evaluation and management across Rio Tinto.

This approach reflects a “three lines of defence” model for the management of risks and controls:

First line of defence: ownership of risk by employees and business leaders.

Second line of defence: control of risk framework and systems of internal control by central support functions and the Risk Management Committee.

Third line of defence: assurance of systems of internal control by Group Internal Audit.

The key risk management responsibilities throughout the Group are outlined below.

Approach

The Group’s approach to risk management and internal control, underpinned by the Risk policy and standards is aimed at embedding a risk-aware culture in all decision-making, and a commitmentcommit us to managing riskmanage risks in a proactive and effective manner. This includes the:

early identification and evaluation of threats and opportunities;

At Rio Tinto, effective risk management requires:

management and mitigation of threats before they materialise and effective response if they do materialise; and

Identifying and evaluating risks that matter most in achieving strategic objectives, so resources can be prioritised in the most efficient and effective way

active pursuit of opportunities to capture value, within agreed risk tolerances.

Effective communication of risk management information to decision makers across the Group, so we can respond at the right level of the organisation

Accountability

Embedding risk awareness into all decision-making processes to support leaders in managing risks proactively and effectively to improve business performance by either creating or protecting value
Clearly defined roles and responsibilities for risk management is clear throughout the Group and is a key performance area for line managers.

To support risk understanding and management at all levels, the Group Risk function provides the necessary infrastructure to support the management and reporting of material risks within the Group, and escalates key issues through the Executive Committee and ultimately to the board, where appropriate.

Group Risk also supports the Risk Management Committee in its review of risk.

Themanagement.

Our process for identifying, evaluating, planning, communicating, and managing material business risks is designed to manage rather than eliminate, threatsuncertainty and, where appropriate, to accept a degree of risk to generate returns. Certain threats,We have an enterprise-wide risk management information system where all material risks, controls and actions are documented and kept current for example natural disasters, cannot be managed using internal controls. Such major threatsmanaging and reporting purposes.


All of our employees and business leaders are transferred to third partiesresponsible for identifying, evaluating and managing risks. Risk management is a key accountability and performance area for our leaders. Our Risk team supports the understanding and management of risks, at all levels of the business. They provide a framework for managing and reporting material risks and support the Risk Management Committee in the international insurance markets,escalating key issues to the extent considered appropriateExecutive Committee or possible.

The Group has material investments in a number of jointly controlled entities. Where Rio Tinto does not have managerial control, it is usually unable to ensure that management will comply with all Rio Tinto policies and standards.

management.

Our risk management framework sets out the organisational foundations for designing, implementing, monitoring, reviewing and continually improving risk management throughout the organisation.
A key element of this framework is our Risk Management Standard. Together with the Group’s Risk Policy, the standard outlines the expected outcomes from risk management, the roles and responsibilities associated with implementing risk analysis and management effectively, and the minimum requirements that must be met.


The framework also defines the oversight responsibilities of the Board and the Executive Committee, supported by Group Internal Audit, the Risk Management Committee and central support functions across our business.
The risk management framework lays out a three tier approach to managing risks and controls:
First line assurance is the role of risk owners and business leaders. Oversight by senior leadership teams through the Risk, Assurance and Compliance forums chaired by product group chief executives and heads of functions.
Second line assurance is provided by our central support functions and technical Centre of Excellence teams eg Underground Mining. As our Group standard-setters, their assurance activities are planned and managed by the Integrated Assurance Office (IAO). Management oversight of this assurance over material Group-level risks is supported by a quarterly Risk Management Committee meeting chaired by the Rio Tinto Group Chief Executive.
Third line assurance is conducted by Group Internal Audit (GIA) to provide independent assurance that the risk management and internal controls are effective to the Board and its sub-committees.

Threats
Failure to manage our health, safety, environment or community risks

Rio Tinto seeks to achieve operational and commercial excellence, and to attract and retain the best people in the industry.

Operational excellence is derived from high operational and human productivity, which requires quality people, processes and systems.

Business interruption may arise from a number of circumstances, including:

  Operational difficulties such as extended industrial dispute, delayed development, bottlenecks or interruptions to infrastructure for power, water and transportation, throughout the value chain.

  Operational failure such as a process safety incident, major pit slope, dump or tailings/water impoundment failure, underground incident.

  Cyber breach/incident of commercial and operational systems.

  Natural disasters such as earthquakes, subsidence, drought, flood, fire and storm can impact mines, smelters, refineries and infrastructure installations. Some of these risks are likely to increase through the impact of climate change.

Legal frameworks with respect to policies such as energy, climate change and mineral law may also change in a way that increases costs.

Closure, reclamation and rehabilitation: risk and uncertainty
Planning for the future of our sites after they cease their operating life is a core business function governed by our Closure Steering Committee.

Disclosure pursuant to Section 13(r) of the Securities Exchange Act of 1934

Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012 added Section 13(r) to the U.S. Securities Exchange Act of 1934 as amended (the “Exchange Act”). Section 13(r) to the Exchange Act requires an issuer to disclose in its annual reports whether it or any of its affiliates knowingly engaged in certain activities, transactions or dealings relating to Iran or with the Government of Iran during the period covered by the report. Disclosure is required even where the activities, transactions or dealings are conducted outside the United States by non-U.S. persons in compliance with applicable law, and whether or not the activities are sanctionable under US law. Pursuant to Section 13(r) of the Exchange Act, the companyThe Company notes the following in relation to activities that took place in 2017,2019, or in relation to activities the companyCompany became aware of in 20172019 relating to disclosable activities prior to the reporting period.

The companyCompany routinely takes action to protect its intellectual property rightsin many countries throughout the world, including Iran. In connection with such protection efforts, the companyCompany has used,, directly or indirectly, patent agentintellectual property firms with an agent or branch office in Iran to assist with the filing of patent and trade-mark applications, prosecution activities and maintenance in Iran. Contact with the firms has been minimal and solely limited to these activities. Certain transactions related to patents, trademarks and copyright are authorised activities under U.SUS sanctions and regulations against Iran (including the filing of an application to obtain a patent or trade-mark in Iran), and although the company is not a U.S person, itCompany believes its limited activities in this regard are consistent with this authorisation.

Rio Tinto acquired its interest in Namibia-based Rössing Uranium Limited (Rössing)(“Rössing”) in 1970. The IranianIran Foreign Investments Company (IFIC)(“IFIC”) acquired its original minority shareholding in Rössing in 1975. IFIC’s interest predates the establishment of the Islamic Republic of Iran and the U.S. economic sanctions targeting Iran’s nuclear, energy and ballistic missile programs. IFIC acquired and continues to own a minority shareholding in Rössing in accordance with Namibian law.

The Treasury Department’s Office of Foreign Assets Control designated IFIC as a Specially Designated National on 5 November 2018.

On 16 July 2019, the Company completed the sale of its entire interest 68.62 per cent stake in Rössing to China National Uranium Corporation Limited (“CNUC”) for an initial cash payment of $6.5 million and a contingent payment of up to $100 million. The contingent payment is linked to uranium spot prices and Rössing's net income during the next seven calendar years. In addition, the Company will receive a cash payment if CNUC sells the Zelda 20 Mineral Deposit during a restricted period following completion. The total consideration is subject to a maximum cap of $106.5 million. Rio Tinto Marketing Pte Ltd will continue to purchase a quantity of uranium produced by Rössing, in order to satisfy existing contractual commitments with customers.
Rössing was neither a business partnership nor joint venture between Rio Tintothe Company and IFIC. Rössing is a Namibian limited liability company with a large number of shareholders includingwhich included Rio Tinto with 68.62 per cent,Tinto.
When the Company was a shareholder, IFIC with 15.29 per cent, the Industrial Development Corporation of South Africa with 10.22 per cent, local individual shareholders with a combined interest of 2.45 per cent and thehad no uranium product off-take rights. Neither IFIC nor other Government of the Republic of NamibiaIran entities had any supply contracts in place with 3.42 per cent but with an additional 50.07 per cent vote at a general meeting of Rössing on matters of national interest.

As a shareholderand none received any uranium from Rössing. IFIC also did not have access to any technology through its investment in Rössing or rights to such technology.

Rio Tinto hashad no power or authority to divest IFIC’s holding in Rössing. However, Rössing and the Namibian Government have taken several recent steps to limit IFIC’s future involvement in Rössing.

On 1 October 2010, Namibia reported to the United Nations, pursuant to Article 31 of the United Nations Security Council Resolution 1929 (UN SCR 1929), that it had reached an agreement with the Islamic Republic of Iran that IFIC will not participate in any future investments nor will it acquire any further shares in Rössing. It was also agreed that the Government of Iran will not acquire interests in any commercial activity in Namibia involving uranium mining, production, or use of nuclear materials and technology, as required under UN SCR1929, until such time as the United Nations Security Council determines that the objectives of the Resolution have been met.

The Rössing board also took steps in 2012 to terminate IFIC’s involvement in the governance of Rössing. AsWhen Rio Tinto was a shareholder in Rössing, IFIC was entitled under Namibian law to attend annual general meetings of Rössing, which they dodid attend. IFIC was previously represented on the board of Rössing by two directors. While this level of board representation did not provide IFIC with the ability to influence the conduct of Rössing’s business on its own, the Rössing board nonetheless determined that, in light of international economic sanctions, it would be in the best interest of Rössing to terminate IFIC’s involvement in board


activity. Therefore, on 4 June 2012, at the annual general meeting of Rössing, the shareholders, ofincluding the company, including Rio Tinto,Company, voted not to re-elect the two IFIC board members. This ended IFIC’s participation in Rössing board activities. IFIC accordingly is not represented on the Rössing board, nor does it have the right to attend board meetings or receive any board information.



While IFIC iswas entitled to its pro rata share of any dividend that the majority of the board may declaredeclared for all shareholders in Rössing, IFIC hashad not received such monies since early 2008. Simply by maintaining its own shareholding in Rössing, Rio Tinto isthe Company was not engaging in any activity intended or designed to confer any direct or indirect financial support for IFIC. A dividend was declared for 2015 in March 2016 and an interim 2016 dividend declared in August 2016 with approximately US$13.6 million (representing IFC’s portion of
While the dividends declared in 2016) deposited into a restricted bank account in Namibia held in favour of IFIC since 2008.

Rössing is one of the world’s largest and longest-operating uranium mines. All of the uranium produced by Rössing is sold to Rio Tinto Marketing Pte. Ltd, (doing business as Rio Tinto Uranium), which re-sells this product to electric utilities in North America, Asia and Europe. As a minority shareholder, IFIC has no uranium product off-take rights. Neither IFIC nor other Government of Iran entities have any supply contracts in place with Rössing and nor receive any uranium from Rössing. IFIC also does not have access to any technology through its investment in Rössing or rights to such technology.

While Rio Tinto doesCompany did not view itself as actively transacting or entering into business dealings with an instrumentality of the Government of Iran or a Specially Designated National, this information has been provided to ensure transparency regarding the passive, minority shareholding in Rössing currently held by IFIC. Rio Tinto has disclosedIFIC while the IFIC shareholding matter to the United States Government and has periodically updated the U.S. Department of State as to the same.

Prices



Prices

The effect ofCommodity price movements on the Group’s commodities in 2017 was to increase2019 increased underlying earningsEBITDA by US$4.1 billion$4,382 million compared with 2016.

The largest contributors to this increase were:2018. This was primarily driven by the strength in the iron ore (US$1.9 billion), aluminium including related products (US$1.0 billion),price and was partly offset by lower prices for copper (US$0.5 billion), Coking coal (US$0.3 billion) and other coal products including thermal coal (US$0.3 billion).

aluminium.

The Platts priceindex for 62 per cent62% iron Pilbara fines was 20 per cent39% higher on average compared with 2016. Achieved average pricing2018 on a free on board (FOB) basis, driven by supply disruptions in 2017the seaborne market and strong demand following record Chinese steel output.
Average London Metal Exchange (LME) prices for copper and aluminium were 8% and 15% lower, respectively, compared with 2018, as global manufacturing activity slowed. The gold price was US$59.6 per wet metric tonne10% higher.
The 10% tariff on an FOB basis (2016: US$49.3 per wet metric tonne). This equates to US$64.8 per dry metric tonne (2016: US$53.6 per dry metric tonne), which compares withUS imports of aluminium from Canada, in place from 1 June 2018, was removed on 19 May 2019, following agreement between the average FOB Platts price of US$64.1 per dry metric tonneUS and Canadian governments. The midwest premium for 62 per cent iron Pilbara fines (2016: US$53.6 per dry metric tonne).

For Aluminium,aluminium in the Group achieved an average realised aluminium price of US$2,231US averaged $320 per tonne - 24% lower than in 2017 (2016: US$1,849 per tonne). This included premia for value-added products (VAP), which represented 57 per cent of primary metal sold in 2017 (2016: 54 per cent) and generated attractive product premia averaging US$221 per tonne of VAP sold (2016: US$223 per tonne) on top of the physical market premia.

The average price of copper increased from 221 US cents per pound to 281 US cents per pound.

Realised hard coking coal prices were 42 per cent higher2018.



Exchange rates
Compared with 2018, on average compared with 2016 and realised thermal coal prices averaged 32 per cent higher.

Exchange rates

Compared with 2016, the US dollar on average, weakenedstrengthened by one per cent7% against the Australian dollar, by 3% against the Canadian dollar weakened by four per cent against the Australian dollar and by ten per cent9% against the South African rand. The effect of all currencyCurrency movements was to decreaseincreased underlying earningsEBITDA by $529 million relative to 20162018.

Volumes
Underlying EBITDA decreased by US$0.3 billion.

Volumes

Movements$20 million compared with 2018 from movements in sales volumes increased earnings by US$0.1 billion compared with 2016. The main contributors were higherand changes in product mix. A 3% decline in iron ore shipments from the Pilbara, where we experienced weather disruptions and operational challenges at some of our mines in the first half of 2019, were mostly offset by increased bauxite shipments, improved aluminium product mix and higher by-product volumes (gold and molybdenum) from Rio Tinto Kennecott and Oyu Tolgoi.

Energy
Average movements in energy prices compared with 2018 improved underlying EBITDA by $75 million, mainly due to lower diesel prices.
Operating cash cost movements*
Our cash operating costs rose by $523 million compared with 2018 (on a 20 per centunit cost basis), primarily reflecting an increase in titanium dioxide slag feedstock sales volumes and a six per cent rise in bauxite sales.

Energy

Higher input energy prices duringiron ore unit costs, driven by the year reduced underlying earnings by US$0.1 billion compared with 2016 in part related to oil, where the average price rose approximately 23 per cent, averaging US$54 per barrel during 2017.

Cash costs, exploration and evaluation

Rio Tinto continued to realise considerable savings from itsfirst half challenges. There was some respite on cost reduction programme, delivering US$0.6 billion pre-tax (underlying earnings impact of US$0.4 billion) comprised of operating cash cost improvements* (US$0.5 billion pre-tax) and reductions in exploration and evaluation cash expenditure (US$48 million pre-tax) in 2017, meeting its US$2.0 billion target over 2016 and 2017 six months earlier than scheduled. The Group has now achieved US$8.3 billion pre-tax (US$5.9 billion post-tax) in total operating cash cost improvements and reductions in exploration and evaluation expenditure compared with the 2012 base. These savings were achieved against a backdrop of risinginflation for certain raw materials costs,for Aluminium, in particular for the Aluminium industry.

The Group continued to optimise its expenditurecaustic soda and petroleum coke. However, this was partly offset by inflationary pressures on exploration and evaluation, progressing the highest value projects.

other costs.

* Operating cash cost improvements represent the difference between the current and prior year full cash cost of sales per unit based on the prior year volume sold. This financial performance indicator is used by management internally to assess performance and therefore is considered relevant to users of the accounts.


Exploration and evaluation spend

We spent $136 million, or 28%, more on exploration and evaluation compared with last year. This went to our highest value projects, particularly on evaluating the Resolution copper project in Arizona, advancing our Winu copper/gold deposit in Australia and progressing our Falcon diamond project in Canada.
One off items

Group one-off

One-off items netted out to be $16 million less than in 2018. 2019 underlying EBITDA includes the impact of US$0.3 billiona $199 million charge at Escondida to reflect the cancellation of existing coal power contracts, a $68 million impact from the curtailment of operations at Richards Bay Minerals (RBM) and $68 million for operational challenges faced at our ISAL and Kitimat aluminium smelters.
In 2018 we suspended operations for two months at Iron Ore Company of Canada before reaching a new labour agreement ($236 million impact). We also suspended production at Rio Tinto Iron & Titanium, following a fatality at our Sorel-Tracy plant and labour disruptions at RBM ($132 million impact).
Non-cash costs/other
The movements in our non-cash costs and other items, which lowered underlying EBITDA by $319 million compared with 2018, reflected significant divestments in 2018 which generated $1,246 million of underlying EBITDA in 2018, primarily the coking coal business and the Grasberg copper mine. Following implementation of IFRS 16 "Leases" on 1 January 2019, a large proportion of our lease expense comprises charges for depreciation and interest and is not included in cash operating costs.  In 2019, there was a consequent benefit to underlying earningsEBITDA of approximately $320 million from this change in treatment.
Depreciation and amortisation, net interest and tax
Our depreciation and amortisation charge was $366 million higher than 2018. This was primarily relatedue to the inclusion of depreciation on leases brought on to the balance sheet on adoption of IFRS 16 and completion of the Amrun bauxite mine. The increase was partly offset by the impact of the strike at Escondidaweaker Australian and Canadian dollars against the US dollar, along with assets divested in 2018.
Interest and finance items (pre-tax) were broadly in line with 2018. This was mainly due to the first half of 2017bond tender we completed in 2018, which resultedreduced our gross debt by $1.9 billion equivalent and incurred $94 million in lower volumes and higher unitearly redemption costs compared with 2016.in 2018. In addition2019, there was also a deferred tax asset write-down at Grasberg. These were partlylower level of average net debt and an increase in capitalised


interest. This was offset by receiptthe inclusion of the final insurance settlement relating to the Manefay slide at Kennecottinterest expense on leases following adoption of IFRS 16 "Leases" in 2013.

Tax / non-cash / interest / other

2019.


The 20172019 effective corporate income tax rate on underlying earnings, excluding equity accounted units, was 28 per cent30%, compared with 22 per cent29% in 2016. The higher tax rate in 2017 primarily reflected increased profit in Australia and the impact of a deferred tax asset write-down relating to Grasberg while the lower rate in 2016 was due to the recognition of a deferred tax asset in Mongolia.2018. The effective tax rate on underlying earnings in Australia remained at 30 per cent. The Group expectswas 31% in 2019 compared with 30% in 2018. We anticipate an effective tax rate on underlying earnings of approximately 3030% in 2020.
Items excluded from underlying earnings
Refer to page 20 below for a detailed reconciliation between underlying earnings and net earnings.
Profit
Net earnings and underlying earnings refer to amounts attributable to the owners of Rio Tinto. The net profit attributable to the owners of Rio Tinto in 2019 was $8.0 billion (2018: $13.6 billion). We recorded a profit after tax in 2019 of $7.0 billion (2018: $13.9 billion) of which a loss of $1.0 billion (2018 profit: $0.3 billion) was attributable to non-controlling interests.
Financial performance of 2018 compared to 2017
2018 net earnings of $13.6 billion were $4.8 billion above the 2017 net earnings of $8.8 billion. The table below lists the principal factors driving the movement in net earnings between periods and reconciles to profit for the year.

(b)Earnings contributions from Group businesses and business segments are based on underlying earnings.
Amounts excluded from net earnings in arriving at underlying earnings are described in “Financial statements Note 2-Operating segments” on page 170 of the Annual report 2019.
Prices
Commodity price movements in 2018 increased underlying EBITDA by $277 million compared with 2017. The FOB (free on board) Platts index for 62% iron Pilbara fines was 4% lower on average compared with 2017. Average LME prices for copper and aluminium were up 6% and 7% respectively, compared with 2017. We also benefitted from higher market premiums for aluminium, in particular the mid-west premium in the US which averaged $419 per centtonne in 2018, a 111% rise on 2017’s $199 per tonne.
On 1 March 2018, the US government announced a 10% tariff on US imports of aluminium from Canada, which it implemented on 1 June 2018.

We do not expect this to have a significant financial impact on our business in the near term.

Exchange rates
Compared with 2017, on average the US dollar strengthened by 3% against the Australian dollar, stayed flat against the Canadian dollar and weakened by 1% against the South African rand. Currency movements increased underlying EBITDA by $286 million relative to 2017.
Volumes
Higher sales volumes increased underlying EBITDA by $863 million compared with 2017, mainly in iron ore and copper/gold. Our Pilbara iron ore shipments rose as we debottlenecked our rail network following full implementation of AutoHaul™ autonomous trains and ramped up production from our new Silvergrass mine. In copper, we benefitted from better operating performance at Escondida including the absence of the labour disruption in 2017, as well as higher copper grades at Rio Tinto Kennecott and higher gold grades at Oyu Tolgoi.
Energy
Higher energy prices compared with 2017 reduced our underlying EBITDA by $436 million. This was mainly due to the average price of oil rising by roughly 31% in 2018 to $71 per barrel. Our Pacific Aluminium smelters were also affected by higher coal prices and a new power contract.
Operating cash cost movements*
Our cash operating costs rose by $750 million compared with 2017. The Groupconsiderable efficiencies we continue to see from our mine-to-market productivity programme were offset by the increasing costs of raw materials – in particular caustic soda, petroleum coke and tar pitch for Aluminium.

* Operating cash cost improvements represent the difference between the current and prior year full cash cost of sales per unit based on the prior year volume sold. This financial performance indicator is used by management internally to assess performance and therefore is considered relevant to users of the accounts.
Exploration and evaluation spend
We spent $43 million more on exploration and evaluation compared with last year. This went to our highest-value projects, particularly the Resolution copper project in Arizona.
One off items
One-off items were $23 million more than in 2017. At Iron Ore Company of Canada, we suspended operations for two months in 2018 ($236 million impact) before reaching a new labour agreement. At Iron & Titanium, production was suspended after a fatality at our Sorel-Tracy plant and labour disruptions at Richards Bay Minerals ($132 million impact). In 2017, our most significant one-off item was the strike action at Escondida, which led to lower volumes and higher unit costs with a $316 million impact.
Non-cash costs/other
The movements in our non-cash costs and other items lowered EBITDA by $317 million compared with 2017. We had $717 million less in underlying EBITDA following the sale of our coal businesses in 2017 and 2018. This was partly offset by the $278 million gain on sale of the Winchester South and Valeria coal development projects and a $167 million revaluation of a royalty receivable arising from the disposal of the Mount Pleasant coal project in 2016.
Our restructuring costs were $95 million higher as we continued our reorganisation around four operating and commercial hubs.


Depreciation and amortisation, net interest and tax
Our depreciation and amortisation charge (net of tax and non-controlling interests) of US$0.4 billion was US$0.2 billion$391 million lower than 2016in 2017, driven by the sale of the thermal coal assets in 2017 and a lower charge at Oyu Tolgoi due to thesome assets being fully depreciated. Interest and finance items (pre-tax) were $385 million lower than 2017. This was due to a lower level of net debt, lower early redemption costs from bond purchases and an increase in capitalised interest. The interest charge included US$0.2In 2018, we completed a bond tender, reducing our gross debt by a further $1.94 billion ofequivalent. We also incurred $94 million in early redemption costs from bond repurchases in 2017 when the Group successfully completed a US$2.5 billion bond tender, and redemption exercise which reduced gross debt. In 2016, similar exercises reduced gross debt by US$7.5 billion,compared with early redemption costs of US$0.2 billion.$256 million in 2017. Since the start of 2016, the Group haswe have reduced the nominal value of outstanding bonds from approximately US$21$21 billion to around US$9.5 billion.



2016 financial performance compared$7.8 billion equivalent, with 2015

2016 underlying earnings of US$5.1 billion and net earnings of US$4.6 billion were US$0.6 billion above and US$5.5 billion above the comparable measures for the previous year respectively (2015 underlying earnings of US$4.5 billion and net losses of US$0.9 billion were US$4.8 billion below and US$7.4 billion below the comparable measures for the previous year respectively). Both net earnings and underlying earnings represent amounts attributable to owners of Rio Tinto.  International Financial Reporting Standards (IFRS) requires that the profit/(loss) for the period reported in the income statement should also include earnings/(losses) attributable to non-controlling interests in subsidiaries.

Prices

Most commodity prices increased for the first time in a number years in the second half of 2016, despite numerous political and macro shocks to the global economy.  However, the effect of all price movementsan average weighted interest rate on the Group’s commodities in 2016 was to decrease underlying earnings by US$0.5 billion compared with 2015.

Major positive price variances were seen in iron ore (US$0.2 billion), coal (US$0.1 billion) and gold (US$32 million).

Iron ore prices started 2016 at US$43 per dry metric tonne cost and freight (CFR) and ended the yearoutstanding bonds of around US$80 per tonne. 5%.

The average realised price for iron ore was up approximately 2% to US$49.3 per wet metric tonne (FOB), from US$48.4 per wet metric tonne (FOB) in 2015.  

Hard coking coal benchmark prices were 12 per cent higher on average compared with 2015 and thermal coal spot prices averaged seven per cent higher. Hard coking coal prices almost quadrupled to US$310


per tonne from January to November 2016. The thermal coal market was also affected, with prices doubling to US$110 per tonne FOB Newcastle. Prices have since moderated.  

These commodity price gains were more than offset by lower average prices for copper and aluminium which were down 11 and three per cent respectively year-on-year, and a significant drop in market premia for aluminium in all regions, which fell from their record highs in early 2015.

Aluminium had a negative price variance of US$0.5 billion. Average London Metal Exchange (LME) prices decreased three per cent year on year, and lower market and product premia resulted in the average realised price per tonne decreasing from US$2,058 in 2015 to US$1,849 in 2016.  

Copper contributed US$0.1 billion to the negative price variance. Additionally lower prices across industrial mineral and Molybdenum contributed US$0.1 billion to the negative price variance.

Exchange rates

Compared with 2015, the US dollar, on average, strengthened by three per cent against the Canadian dollar, by one per cent against the Australian dollar and by 14 per cent against the South African rand. The effect of all currency movements was to increase underlying earnings relative to 2015 by US$49 million.

Volumes

Movements in sales volumes increased earnings by US$19 million compared with 2015. There were volume gains in iron ore, following the increase in capacity at the Pilbara ports and mines, in bauxite, from increased production at all four mines, and in aluminium following record production at ten smelters. These were mostly outweighed by lower sales volumes in copper, gold and molybdenum.

Energy

Lower input energy prices during the year improved underlying earnings by US$25 million compared with 2015 in part related to oil, where the price fell approximately 16 per cent year-on-year, averaging US$44 per barrel during 2016.

Cash costs, exploration and evaluation

Rio Tinto continued to realise considerable savings from its cost reduction programme, delivering US$1.6 billion pre-tax (US$1.2 billion post tax) in operating cash cost savings and reductions in exploration and evaluation expenditure in 2016.

The Group continued to optimise its expenditure on exploration and evaluation, progressing the highest value projects. In 2016, approximately 41 per cent of this expenditure was incurred by central exploration, 25 per cent by Copper & Diamonds, 25 per cent by Energy & Minerals and the remainder by Aluminium and Iron Ore.

Tax / non-cash / interest / other

The 20162018 effective corporate income tax rate on underlying earnings, excluding equity accounted units, was 22 per cent29%, compared with 27 per cent28% in 2015. The lower effective tax rate in 2016 was largely due to the recognition of a deferred tax asset in Mongolia. Excluding this item, the effective tax rate in 2016 was 26 per cent.2017. The effective tax rate on underlying earnings in Australia remained at 30 per cent.

in both years was just over 30%.

2019
Net impairment charges increased by $1.6 billion compared with 2018, primarily related to the Oyu Tolgoi underground project in Mongolia and the Yarwun alumina refinery in Queensland, Australia. We recognised an impairment charge of $0.8 billion (after tax and non-controlling interests) on the Oyu Tolgoi project, reflecting forecast delays to first production and increased capital spend on the development. We also recognised a $0.8 billion post-tax impairment charge on the Yarwun alumina refinery following ramp-up of the Amrun expansion at Weipa, which resulted in a reassessment of our cash generating units. Weipa is now considered to generate cash inflows largely independent from the downstream alumina operations with which it was previously aggregated for accounting purposes.
In 2018, we recognised $0.1 billion of after tax charges, mainly relating to the carrying value of the ISAL aluminium smelter in Iceland following its reclassification to assets held for sale. In 2019, we recognised a further $0.1 billion post-tax charge as these assets were reclassified back out of assets held for sale.


Gains on disposals were $4.3 billion lower than 2018. In 2019, we recognised a $0.3 billion loss (after tax) from the sale of Rössing Uranium, including a non-cash adjustment for historical foreign exchange losses. In 2018, we realised net gains of $4.0 billion (after tax), primarily from the sale of our Hail Creek and Kestrel coking coal businesses in Australia, the sale of our interest in the Grasberg copper mine in Indonesia and the formation of the ELYSIS joint venture in Canada.
Exchange differences and gains/losses on derivatives were $0.9 billion lower than 2018. In 2019, these gave rise to a $0.2 billion after tax loss. This compared with gains of $0.7 billion in 2018 - mainly on US dollar debt in non-US dollar functional currency Group companies, intragroup balances and on the revaluation of certain derivatives which do not qualify for hedge accounting. These exchange gains are largely offset by currency translation losses recognised in equity. The quantum of US dollar debt is largely unaffected and we will repay it from US dollar sales receipts.
There were $0.4 billion in other changes in items excluded from underlying earnings. In 2019, we recognised a $0.2 billion loss (after tax) related to provisions for obligations in respect of legacy operations. In 2018, we recognised a $0.6 billion gain on sale of surplus land at Kitimat and a $0.3 billion increase in the closure provision at the Argyle diamond mine.
2018
In 2018, we recognised $104 million of post-tax impairment charges, mainly relating to the carrying value of the ISAL aluminium smelter in Iceland following its reclassification to assets held for sale. In 2017,

we recognised $481 million (post-tax) of impairment charges, relating primarily to the carrying values of the Roughrider uranium deposit in Canada, the Rössing Uranium mine in Namibia and the Argyle diamond mine in Australia.

2018 net gains on consolidation and disposal of interests in businesses of $4.0 billion (post-tax) included the sale of our Hail Creek and Kestrel coking coal businesses in Australia, the sale of our interest in Grasberg in Indonesia and the formation of the ELYSIS joint venture in Canada. We created this joint venture in May with Alcoa to develop a carbon-free aluminium smelting process and recognised a gain of $141 million (post-tax) for the fair value uplift on forming the joint venture. In 2017, we realised net gains on disposal of interests in businesses of $2.0 billion from the sale of the Coal & Allied thermal coal business in Australia.
Amounts relating to the undeveloped coal properties, Winchester South and Valeria, were included within underlying earnings.
In 2018, we recognised non-cash exchange and derivative gains of $0.7 billion. This was mainly on US dollar debt in non-US dollar functional currency Group companies, intragroup balances, and on the revaluation of certain derivatives which did not qualify for hedge accounting. The exchange gains were largely offset by currency translation losses recognised in equity. The quantum of US dollar debt was largely unaffected.
Other exclusions of $0.2 billion included gains on the sale of surplus land at Kitimat in Canada ($0.6 billion), partially offset by charges recognised to increase closure provisions at ERA and Argyle in Australia ($0.3 billion).
2017
Impairment charges of US$481$481 million (post-tax) were recognised in 2017, relating2017. This related primarily to the carrying values of the Roughrider uranium deposit in Canada, the Rössing uranium mine in Namibia and the Argyle diamond mine in Australia. Roughrider’s recoverable amount was determined to be nil$nil following a decision in the first half of 2017 to cease further expenditure on the project. Rössing was impaired due to oversupply in the uranium market resulting in structural changes to forecast prices, while the impairment at Argyle was attributable to lower production volumes, a smaller than expected contribution from productivity improvements and lower realised prices.

Net gains on disposal of interests in businesses of US$2,022$2,022 million primarily related to the sale of the Coal & Allied thermal coal business which completed on 1 September 2017.

Non-cash exchange and derivative losses in 2017 of US$810$810 million arose primarily on US dollar debt in non-US dollar functional currency Group companies, intragroup balances, and on the revaluation of certain derivatives which do not qualify for hedge accounting. TheseThe exchange losses were in contrast to net exchange and derivative gains in 2016 of US$536 million, giving rise to a negative period-on-period movement of US$1,346 million. The exchange losses are largely offset by currency translation gains recognised in equity and the quantum of US dollar debt, which will be repaid from US dollar sales receipts and US dollar divestment proceeds, is therefore largely unaffected.

Deferred tax assets have beenwere remeasured to reflect lower corporate income tax rates in the US and France as a resultsresult of tax legislation changes. Deferred tax assets havewere also been derecognised as a result of revised profit forecasts in France due to expected divestments.



In 2017, the Group received the final settlement on the insurance claims related to the 2013 pit-wall slide at Rio Tinto Kennecott of US$233$233 million pre-tax (US$($146 million post-tax). Part of the settlement, US$73$73 million pre-tax (US$($45 million post-tax), has beenwas excluded from underlying earnings in line with the treatment of associated costs incurred from 2013 to 2015.


2016

Impairment charges during the year ended 31 December 2016 primarily related to the Argyle diamond mine in Western Australia. An impairment trigger assessment at the Argyle diamond mine cash-generating unit resulted in the identification of impairment indicators as a result of lower production volumes compared with forecast and the lower prices achieved for bulk diamonds.  The reduction in the recoverable amount resulted in a pre-tax impairment charge of US$241 million to property, plant and equipment and intangible assets.

Net gains on disposal of interests in businesses in 2016 related mainly to the sale of Rio Tinto’s 40 per cent interest in the Bengalla Joint Venture on 1 March 2016 and the sale of the Lochaber assets in Scotland on 23 November 2016.  This was partially offset by a loss on disposal of the 100 per cent interest in Carbone Savoie on 31 March 2016.

Net exchange gains in 2016 comprised post-tax foreign exchange gains of US$123 million principally on external US dollar denominated net debt in non-US dollar functional currency companies (on borrowings of approximately US$17.6 billion), and US$393 million of gains on intragroup balances mainly as the Canadian dollar  strengthened against the US dollar compared to 31 December 2015.  The Group took further steps during 2016 to reduce the income statement exposure on retranslation of intragroup balances.  The remaining US$20 million related to valuation changes on commodity, currency and interest rate derivatives which are ineligible for hedge accounting.

A review of the infrastructure capacity requirements in Queensland, Australia, confirmed that it was no longer likely that Rio Tinto would utilise the Abbot Point Coal Terminal and associated rail infrastructure capacity contracted under take or pay arrangements. On 31 October 2016, an agreement was reached with Adani, the owner of the port, to relinquish that capacity. Accordingly, an onerous contract provision was recognised based on the net present value of expected future cash flows for the port and rail capacity discounted at a post-tax real rate of two per cent, resulting in a post-tax onerous contract charge of US$329 million.

Tax provision includes amounts provided for specific tax matters for which the timing of resolution and potential economic outflow are uncertain. During 2016 a provision was made in relation to matters under discussion with the Australian Taxation Office (ATO) relating to the transfer pricing of certain transactions between Rio Tinto entities based in Australia and the Group’s commercial centre in Singapore for the period since 2009.

The increase in closure provision (non-operating sites) related to the Gove alumina refinery in Northern Territory, Australia where operations have been curtailed since May 2014.  The provision was updated based on the current cost estimates from the studies.  Future revisions to the closure cost estimate during the study periods (including the next stage of feasibility study) will continue to be excluded from underlying earnings as the site operating assets have been fully impaired.

2015

Total impairment charges of US$1,802 million (post-tax) were recognised in 2015. On 26 May 2014, Rio Tinto and its Simandou iron ore project partners signed an Investment Framework with the Government of Guinea which provided the legal and commercial foundation for the project and formally separated the infrastructure and mine development plan.  The Simandou project partners were finalising an integrated Bankable Feasibility Study (BFS) for the mine, port and infrastructure elements of the project, which was scheduled to be submitted to the Government of Guinea in May 2016. As a result of current market conditions and uncertainty over infrastructure ownership and funding at that time, the Group determined that it was appropriate to record a non-cash impairment charge of US$1,118 million (net of non-controlling interests and tax).

On 11 June 2015, Rio Tinto announced that it supported Energy Resources of Australia Ltd’s (ERA) decision not to proceed with the final Feasibility Study of the Ranger 3 Deeps project.  Rio Tinto also determined it did not support any further study or future development of Ranger 3 Deeps due to the project’s economic challenges.  This resulted in a write down to property, plant and equipment, intangible assets and deferred tax assets to fully write off these long-term assets. The total impairment charge recognised was a non-cash charge of US$262 million (net of non-controlling interests and tax).


In late 2015, Rio Tinto completed an Order of Magnitude study on the Roughrider uranium project in Canada. This led to the Group recognising a post-tax impairment charge of US$199 million relating to goodwill and intangible assets.

Other impairment charges during the year reflect challenging economic conditions at business units in the Group’s Aluminium and Copper & Diamonds product groups.

Non-cash exchange and derivative losses of US$3,282 million (post-tax) arose primarily on US dollar debt in non-US dollar functional currency Group companies, intragroup balances, and on the revaluation of certain derivatives which do not qualify for hedge accounting.

During 2015, the Group incurred US$258 million (post-tax) of restructuring costs associated with its ongoing costs reduction programme.

A post-tax charge of US$233 million was recognised for the remediation of legacy properties, including the Holden Mine in the US.

The above table shows published prices for Rio Tinto’s commodities for the last three years where these are publicly available, and where there is a reasonable degree of correlation between the published prices and Rio Tinto’s realised prices.

Group sales revenue will not necessarily move in line with these published prices for a number of reasons which are discussed below.



The discussion of revenues below relates to the Group’s gross revenue from sale of commodities, as included in the “Financial information by business unit” on pages 206252 to 208254 of the Annual Report 2017.

Iron Ore

2017

2019 sales revenue compared with 2016

2018

Gross sales revenue increased by US$3.6$5.4 billion (25%(29%) to US$18.3 billion.

Sales volumes were one per cent$24.1 billion in 2019. The gross sales revenue for our Pilbara operations included freight revenue of $1.7 billion (2018: $1.7 billion).

The significant increase is attributable to higher than 2016 sales, reflecting ongoing productivity improvements being made toprices as the rail network, along with increased flexibility across the infrastructure system. AchievedPlatts index for 62% iron fines was 39% higher on average pricing was also higher in 2017, US$59.6 per wet metric tonne on an FOB basis compared with US$49.3 per wet metric tonne in 2016.

Approximately 67 per cent2018 on a free on board (FOB) basis. This was partly offset by the effect of lower shipments from the Pilbara, which decreased 3% from the previous period to 327 million tonnes.

In 2019, we priced approximately 76% of our sales in 2017 were priced with reference to the currentaverage index price for the month average, 17 per centof shipment and 16% with reference to the prior quarter’s average index lagged by one month, five per cent with reference to the current quarter average and 11 per cent were sold on fixed terms on the spot market. Index prices are adjusted for product characteristics and iron and moisture content.

2016 sales revenue compared with 2015

Gross sales revenue increased by US$0.7 billion (approximately five percent) to US$14.6 billion.  Sales volumes were three per cent higher in 2016, attributable to the newly expanded infrastructure and minimal disruption from weather events.  The average realised price for iron ore was also up approximately 2% to US$49.3 per wet metric tonne (FOB), from US$48.4 per wet metric tonne (FOB) in 2015.


Approximately 20 per cent of sales in 2016 were priced with reference to the previous quarter’s average index lagged by one month. The remainder was sold either on current quarter average, current month average or on the spot market.

Aluminium

2017We made approximately 68% of sales including freight and 32% on an FOB basis.

In 2019, we achieved an average iron ore price of $79.0 per wet metric tonne on an FOB basis (2018: $57.8 per wet metric tonne). This equates to $85.9 per dry metric tonne (2018: $62.8 per dry metric tonne).
2018 sales revenue compared with 2016

2017

Gross sales revenue increased by $0.3 billion (1%) to $18.7 billion in 2018 (2018 revenue numbers have been adjusted to take into account Dampier salt being reclassified under the Iron Ore product group in 2019). This included freight revenue for the Pilbara operations of $1.7 billion compared with $1.5 billion.
The small increase was primarily driven by increasing shipments by 2% to 338 million tonnes which was offset by lower prices. The average FOB Platts index for 62% Pilbara fines dropped by 4%.
In 2018, we priced approximately 68% of our sales with reference to the current month average index; 17% with reference to the prior quarter’s average index lagged by one month; 5% with reference to the current quarter average; and 10% on the spot market. Approximately 32% of our sales were made on an FOB basis with the remainder sold including freight.
In 2018, we achieved an average iron ore price of $57.8 per wet metric tonne on an FOB basis (2017: $59.6 per wet metric tonne). This equates to $62.8 per dry metric tonne (2017: $64.8 per dry metric tonne), which compares with the average FOB Platts index of $61.8 per dry metric tonne for the 62% iron Pilbara fines product (2017: $64.1 per dry metric tonne).
Aluminium
2019 sales revenue compared with 2018
Aluminium’s sales revenues are from aluminium and related products such as alumina and bauxite.

Gross sales revenue decreased by 15% to $10.3 billion in 2019. This reflects the significant price declines in alumina and aluminium metal offset by increases in third-party bauxite sales.
In 2019 we achieved an average realised aluminium price of $2,132 per tonne (2018: $2,470 per tonne). This comprised the LME price, a market premium and a value-added product (VAP) premium. The cash LME price averaged $1,791 per tonne, 15% lower than 2018. In our key US market, the midwest premium dropped 24% to $320 per tonne on average in 2019. VAP represented 51% of the primary metal we sold (2018: 54%, excluding the Dunkerque smelter which we sold in 2018) and generated attractive product premiums averaging $234 per tonne of VAP sold (2018: $227 per tonne). We paid a 10% tariff on our Canadian aluminium exports to the United States under Section 232 until the tariff was removed on 19 May 2019.
2018 sales revenue compared with 2017
Gross sales revenue increased by 16%11% to US$11.0$12.2 billion in 2017. The 2017 cash LME aluminium price averaged US$1,969 per tonne, an increase2018. This reflected the stronger pricing environment, in particular for primary metal in the first half of 23 per cent on 2016,the year. This was however this was partially offset by lower salesvolumes. The lower volumes were primarily due to operational issues at Sohar and curtailmentlabour disruptions at the Boyne Smelter.

Strong bauxite production performance, combined with robust demand from China, enablednon-managed Becancour smelter in Canada and a power interruption at the Group to increase its share of third party bauxite shipments by ten per cent to 32.3 million tonnes (2016: 29.3 million tonnes).

2016 sales revenue compared with 2015

There wasDunkerque smelter in France.

In 2018, we achieved an overall decrease in gross sales revenue of US$0.7 billion (approximately seven per cent) to US$9.5 billion in 2016.  Average LME prices decreased three per cent year on year, and lower market and product premia resulted in the average realised aluminium price of $2,470 per tonne decreasing from US$2,058(2017:$2,231 per tonne). This comprised the LME price, a market premium and a value-added product (VAP) premium. The cash LME price averaged $2,110 per tonne, 7% higher than 2017. Market premiums increased in 2015all regions. In our key US market,


the mid-West premium rose 111% to US$1,849$419 per tonne (2017: $199 per tonne), driven by the 10% US tariff implemented on 1 June which is included in 2016.  This realised price included premia for value-added products (VAP), whichour operating costs. VAP represented 57% of the primary metal we sold (2017: 57%) and generated attractive product premiapremiums averaging US$223$227 per tonne of VAP sold (2015: US$251(2017: $221 per tonne) on top of the physical market premia.  In the US, the Mid-West market premium averaged US$162 per tonne in 2016, compared with an average US$271 per tonne in 2015, a 40 per cent decrease.  

Gross sales revenue for bauxite in 2016 decreased seven per cent to US$1.9 billion. Declines in bauxite pricing compared with 2015 were partially offset by continued increase in third party bauxite sales. There was a ten per cent increase in third party bauxite shipments.

Copper &and Diamonds

2017

2019 sales revenue compared with 2016

2018

Gross sales revenue increasedof $5.8 billion was 10% lower than 2018. This reflected lower average realised copper prices and lower grades at all our operations, resulting in lower mined and refined copper production volumes. The impact was partly offset by 7higher throughput from Escondida, productivity improvements at Oyu Tolgoi and improvements in ore processed at Kennecott.
Our average realised copper price decreased by 7% to 275 US cents per centpound, which was comparable with an 8% decline in 2017the LME price to 273 US cents per pound.
2018 sales revenue compared with 2016.

Copper2017

Gross sales revenue of $6.5 billion was 34% higher than in 2016 as the average2017. This reflected increased copper and gold volumes which were driven by higher grades. The rise is also connected to productivity improvements and increased plant throughput at Rio Tinto Kennecott, a return to capacity at Escondida, higher gold grades at Oyu Tolgoi, and a greater metal share at Grasberg.
Average LME copper priceprices increased by 27 per cent6% to 281297 US cents per pound, and the average gold price increased by onerose 1% to $1,269 per cent to US$1,257 per ounce. This was partiallyounce compared with 2017. These price rises were more than offset by the impact of lower sales volumes (13% lower than 2016), mainly due to the impact of a strike at Escondida in the first quarter of 2017.

Diamonds revenue increased 15 per cent to US$0.7 billion in 2017, reflecting higher sales volumes, including the effect of factories in India increasing manufacturing capacity as the market normalised following Indian banknote reform in 2016,provisional pricing movements.

Energy and the outlook in key emerging markets improved. This resulted in sustained re-stocking activity throughout the pipeline for most of the year.

At 31 December 2017, the Group had an estimated 250 million pounds of copper sales that were provisionally priced at 304 US cents per pound. The final price of these sales will be determined during the first half of 2018. This compares with 235 million pounds of open shipments at 31 December 2016, provisionally priced at 250 cents per pound.

2019 sales revenue compared with 2015

Overall gross2018

Gross sales revenues for the product group in 2019 fell by 6% to $5.2 billion.
Excluding the contribution from the divested coal business in 2018, 2019 revenue declined by 19 per cent to US$4.5of $5.2 billion was 15% higher than 2018. The increase reflects the recovery in 2016.  

Copper sales revenue was lower than 2015 as a result of lower sales volumes along with an 11 per cent decline in prices to 221 US cents per pound in 2016.  Gold revenue was lower than 2015 due mainly to


lower grade and volumes. This was partially offset by an eight per cent increase in the gold price to US$1,250 per ounce.  

At 31 December 2016, the Group had an estimated 235 million pounds of unsettled copper sales (2015: 252 million pounds) that were provisionally priced at 250 US cents per pound (2015: 217 US cents per pound). The final price of these sales was determined during the first half of 2017.

The overall decline in diamonds revenue was attributable to lower sales volumes. Diamond prices realised by Rio Tinto depend onIron & Titanium and Iron Ore Company of Canada and higher prices for iron ore pellets and concentrate and titanium dioxide feedstocks.

IOC production was 18% higher than 2018, when operations were impacted by a two-month strike.
Titanium dioxide feedstock production was 8% higher than 2018, reflecting improved operational performance and the size and qualityrestart of diamonds in the product mix.

2017

Gross sales revenue for the product group in 2017 of US$7.82018 fell by 28% to $5.5 billion (2018 revenue numbers have been adjusted to take into account Dampier salt being reclassified under the Iron Ore product group in 2019). Coal revenue was 15 per cent higher than 2016 as a result of higher prices and higher sales volumes across most products.

Gross sales revenue for Rio Tinto Coal Australia of US$2.8$1.8 billion in 2017 was seven per cent higher than 2016, despite the impact oflower due to the sale of Coal & Allied Industries Limited in September 2017. The Group achieved hard2017 and the sale of the remaining coking coal pricesassets in the current year.

Excluding the entire contribution from coal in both years, 2018 revenue of US$169 per tonne, on average, in$4.5 billion was 5% lower than the 2017 on an FOB basis (2016: US$119 per tonne). Average prices realised for thermal coal were US$78 per tonne on an FOB basis in 2017 (2016: US$60 per tonne).

Gross sales revenue atcomparative of $4.7 billion (both amounts have been adjusted to take into account Dampier salt being reclassified under the Iron Ore Company or Canada (IOC)product group in 2019). This reflected lower volumes in iron ore and titanium dioxide feedstocks, partly offset by higher prices.

IOC production and sales in 2018 were affected by a two-month strike at the mine in the second quarter. Pellet production of US$1.9 billion8.5 million tonnes (our share 5.0 million tonnes) was 41 per cent higher18% lower than 2016, driven2017, while concentrate production for sale of 6.7 million tonnes (our share 3.9 million tonnes) was 22% lower. Total sales of pellets and concentrates in 2018 were 15.0 million tonnes (our share 8.8 million tonnes), 21% lower than 2017.
Titanium dioxide feedstock production was 15% lower in 2018 compared with 2017 although the resulting impact on revenue was offset by higher prices and a five per cent increase in production.

Market conditions for titanium dioxide continueddue to improve in 2017, with strengthening pigment prices supported by low inventorystronger demand and tight supply. Consequently, feedstock demand has improved year-on-year. Improved conditions have also been evident



Cash flow
2019 cash flow compared with 2018
We generated $14.9 billion in net cash from our operating activities, 26% higher than 2018. This increase was driven primarily by higher underlying EBITDA from higher iron ore prices and the zircon market.

Borates demand growth was primarily driven byongoing management of working capital. We invested $5.5 billion in capital expenditure in 2019 which remains at the agriculturesame level as 2018. Key projects included the Koodaideri iron ore mine and construction sectors in 2017. Offtake across most regions held firm, although borates demand in China was impacted by environmental-related shutdowns during the third quarter.

The uranium market remained oversupplied in 2017, with many market players along the value chain reporting excess inventories. The spot price fell from US$26 per pound in the first quarter to below US$21 per pound for muchcompletion of the year until capacity curtailment announcements boosted spot prices asprimary production shaft at Oyu Tolgoi, along with sustaining capital spend.

We generated $9.2 billion of free cash flow, 31% higher than 2018, reflecting our higher operating cash flow and consistent capital expenditure. Free cash flow now includes an adjustment to include lease principal repayments of $315 million following adoption in 2019 of IFRS 16 "Leases".

2016 sales revenue compared with 2015

Gross sales revenues decreased by six per cent compared with 2015, down US$0.4 billion to US$6.7 billion.  

An increase in iron ore sales volumes from Iron Ore Company of Canada (IOC) of two per cent and stronger realised prices had a favourable impact on sales revenues.  This was offset by the impact of lower freight revenue.

Hard coking coal benchmark prices were 12 per cent higher on average compared with 2015 and thermal coal spot prices averaged seven per cent higher.  The favourable impact of price changes was offset by the impact of the Coal & Allied restructure and the divestment of Bengalla.

Titanium dioxide feedstock demand remained subdued throughout 2016 as the industry continued to absorb excess inventories, resulting in continued price pressure, although there are signs of underlying demand improvement for both sulphate and chloride feedstock.  The market for zircon has recently stabilised following an initial period of weak demand in China.   Demand for borates has remained stable globally, with robust demand in the Americas and India partly offset by weaker growth in China and weather-related demand constraints in south-east Asia.

2019.

Uranium prices fell through the latter half of 2016, due to lacklustre demand growth and oversupply. The uranium spot price index ended the year 41 per cent below 2015 at US$20.25 per pound, while the long-term price indicators lost 32 per cent to end the year at US$30.00 per pound. Rio Tinto Uranium also sells predominantly on a longer-term contract basis.

2018 cash flow compared with 2017
We generated $11.8 billion in net cash from our operating activities, of US$13.9 billion15% lower than in 2017. This reduction was 64 per cent higher than 2016primarily driven by higher commodity prices and cash cost improvements, partly offset by higher tax payments from increased underlying profits.

Purchases of property, plantrelated to our 2017 profits and equipment and intangible assets were US$4.5adverse working capital movements. We invested $5.4 billion in 2017, a rise of 49 per cent compared with 2016. Major capital projectsexpenditure, 21% more than in 2017 as our major projects ramped up. These included the development of theour Oyu Tolgoi underground copper mine in Mongolia, constructionthe completion of key infrastructure at theour Amrun bauxite project in Queensland and completionthe full implementation of AutoHaul™, the Silvergrass iron ore mine in the Pilbara.

We generated US$9.5$7.0 billion of free cash flow, 64 per cent higher27% lower than 2017. This included US$0.4 billion of productivity gains from the mine-to-market productivity programme which was implemented2017, in 2017, targeting the delivery of US$5.0 billion of additional freeline with our lower operating cash flow from 2017 to 2021.

Dividends paid in 2017 of US$4.2 billion reflected the 2016 final dividend paid in April 2017, and the 2017 interim dividend paid in September 2017. Share repurchases totalled US$2.1 billion comprised of the US$1.5 billion on-market buy-back in Rio Tinto plc shares and the US$0.6 billion (AUD$0.8 billion) off-market buy-back in Rio Tinto Limited shares.

In 2017, disposals of subsidiaries, joint ventures and associates mainly related to the cash proceeds received to date for the sale of Coal & Allied Industries Limited of US$2.54 billion (net of workinghigher capital adjustments and cash transferred on disposal) and also included receipts of the second and final instalment of funds for Rio Tinto’s disposal of its 100 percent interest in Lochaber, whichexpenditure. This was completed in November 2016.

Rio Tinto completed a US$2.5 billion (nominal value) bond buy-back programme in June 2017. Net interest paid included US$0.3 billion being the payment of the premiums and the accelerated interest associated with the bond redemption. In addition, US$7 million was paid relating to the close out of interest rate swaps and was recognised in other financing cash flows.

2016 compared with 2015

Net cash generated from operating activities of US$8.5 billion was ten per cent lower than 2015. 2015 cash flows benefited from a significant working capital reduction. 2016 saw a rebound in receivables, driven by higher year-end prices. In addition, there was an increase in interest paid to US$1.3 billion, of which US$0.5 billion related to early redemption costs associated with the bond repurchase programmes. These were partly offset by cash cost improvements and lower tax payments, in line with lower underlying profits.

Purchases of property, plant and equipment and intangible assets were US$3.0 billion in 2016, a decline of 36 per cent compared with 2015. Some major capital projects were completed in 2015, including expansion of the Pilbara iron ore infrastructure and the modernisation and expansion of the Kitimat aluminium smelter. Major capital projects in 2016 included the development of the Oyu Tolgoi underground copper mine in Mongolia, construction of key infrastructure at the Amrun bauxite project in Queensland and completion of the Silvergrass iron ore mine in the Pilbara.

Dividends paid in 2016 of US$2.7 billion reflected the final 2015 dividend paid in April 2016 and the 2016 interim dividend paid in September 2016.


In 2016, net proceeds from the disposal of subsidiaries, joint ventures and associates of US$0.8 billion related primarily to amounts received following the disposal of the Group’s 40 per cent interest in the Bengalla Joint Venture and the first tranche from the sale of the Lochaber aluminium assets. In addition, the Group realised US$0.4 billion from the sale of property, plant and equipment including $0.5 billion received from the sale of surplus land at Kitimat. In 2018, our mine-to-market productivity programme exit rate was impacted by $0.3 billion of raw material cost headwinds. We are on track to be generating $1.5 billion per year in free cash flow from this programme from 2021.

We paid $5.4 billion in dividends to our shareholders. We also repurchased $5.4 billion of our shares: $2.1 billion of these were bought off-market in Australia and intangibles, which included$3.3 billion on-market in the Mount Pleasant thermal coal assetsUK in New South Wales, undeveloped land in Utah and some office buildings in North America.

Foreign exchange

The following sensitivities give the estimated effect on underlying earnings assuming that each exchange rate movedmoves in isolation. The relationship between currencies and commodity prices is a complex one and movements in exchange rates can cause movements in commodity prices and vice versa. Where the functional currency of an operation is that of a country for which production of commodities is an important feature of the economy, such as the Australian dollar, there is a certain degree of natural protection against cyclical fluctuations, in that the currency tends to be weak, reducing costs in US dollar terms, when commodity prices are low, and vice versa.

10.E Taxation

US residents

The following is a summary of the principal UK tax, Australian tax and US Federalfederal income tax consequences of the ownership of Rio Tinto plc ADSs, Rio Tinto plc shares and Rio Tinto Limited shares, “the Group’s ADSs and shares”, by a US holder as(as defined below.below). It is not intended to be a comprehensive description of all the tax considerations that are relevant to all classes of taxpayer. This summary does not cover all aspects of US federal income taxation that may be relevant to, or the actual tax effect that any of the matters described herein will have on, the acquisition, ownership, or disposal of the Group’s ADSs and shares by particular investors (including the alternative minimum tax or net investment income tax). Future changes in legislation may affect the tax consequences of the acquisition, ownership or disposal of the Group’s ADSs and shares.

This summary is based in part on representations by the Group’s depositary bank as depositary for the ADRs evidencing the ADSs and assumes that each obligation in the deposit agreements will be performed in accordance with its terms.


You are a US holder if you are a beneficial owner of the Group’s ADSs and shares and you are for US federal income tax purposes: a citizen or resident of the US; a domestic corporation;corporation created or organised under the laws of the United States, any state thereof or the District of Columbia; an estate whose income is subject to US federal income tax regardless of its source; or a trust if a US court can exercise primary supervision over the trust’s administration and one or more US persons are authorised to control all substantial decisions of the trust.

This section applies to US holders only if sharesthe Group’s ADSs or ADSsshares are held as capital assets for US federal income tax purposes. This section does not address tax considerations applicable to investors that own (directly, indirectly, or by attribution) 5% or more of the stock of the Companycompany (by vote or value) and does not apply to shareholders who are members of a special class of holders subject to special rules, including a dealer in securities, a trader in securities who elects to use a mark-to-market method of accounting for securities holdings, a tax exempt organisation, a life insurance company, a person that actuallyholds the Group ADSs or constructively owns five per cent or more of Rio Tinto’s voting stock, a person that holds shares or ADSs as part of a straddle or a hedging or conversion transaction, persons that have ceased to be US citizens or lawful permanent residents of the United States, investors holding sharesthe Group ADSs or ADSsshares in connection with a trade or business conducted outside of the United States, US expatriates or a person whose functional currency is not the US dollar.

This section is based on the US Internal Revenue Code of 1986, as amended (the Code), its legislative history, existing and proposed regulations, published rulings and court decisions, UK and Australian tax law and practice, UK tax law as applied in England and Wales and HM Revenue & Customs published practice (which may not be binding on HM Revenue & Customs) and on the convention between the US and UK, and the convention between the US and Australia (together, the Conventions) which may affect the tax consequences of the ownership of the Group’s ADSs and shares, all as of the date hereof. These laws and conventions are subject to change, possibly on a retroactive basis.

For the purposes of the Conventions and of the Code, US holders of ADSs are treated as the owners of the underlying shares.

basis.

The summary describes the treatment applicable under the conventions in force at the date of this report.

UK taxation of shareholdings in Rio Tinto plc

This section is based on the assumption that for UK tax purposes a US holder who holds ADRs evidencing ADSs will be treated as the owner of the underlying shares represented by the ADSs. Case law in the UK has cast doubt on this view; however HM Revenue & Customs have stated that they will continue to apply their practice of regarding the holder of an ADR as having a beneficial interest in the underlying shares.
Taxation of dividends

Under current UK tax legislation, no withholding tax is required to be withheld from dividends paid by Rio Tinto plc. Where dividends are paid by Rio Tinto plc to a US holder who is not resident in the UK and who does not hold the shares or ADSs in connection with a branch, agency or permanent establishment in the UK, no liability to UK tax will generally arise to the US holder in respect of such dividends.






Capital gains

A US holder, who has at no time been resident in the UK, will not normally be liable to UK tax on capital gains realised on the disposition of a Rio Tinto plc ADS or share unless the holder carries on a trade, profession or vocation in the UK through a branch, agency or permanent establishment in the UK and the ADS or share has been used for the purposes of the trade, profession or vocation or is acquired, held or used for the purposes of such a branch, agency or permanent establishment.

Inheritance tax

Under the UK/US Estate Tax Treaty, a US holder, who is domiciled in the US and is not a national of the UK, will not (provided any US federal or estate gift tax chargeable has been paid) be subject to UK inheritance tax upon the holder’s death or on a transfer during the holder’s lifetime, unless the ADS or share (i) forms part of the business property of a permanent establishment in the UK, (ii) pertains to a fixed base situated in the UK used in the performance of independent personal services, or (iii) is comprised in a settlement (unless, at the time the settlement was made, the settlor was domiciled in the US and was not a national of the UK). Where an ADS or share is subject to both UK inheritance tax and US Federal gift or estate tax, tax payments are relieved in accordance with the priority rules set out in the Treaty.


Stamp duty and stamp duty reserve tax

UK stamp duty should not be required to be paid in respect of a transfer of Rio Tinto plc ADSs provided that the transfer instrument is not executed in, and at all times remains outside, the UK and does not relate to any property situate or to any matter or thing to be done in the UK. Electronic “paperless” purchases of Rio Tinto plc shares are subject to stamp duty reserve tax (SDRT) at a rate of 0.5%. of the amount or value of the consideration payable for the transfer. Purchases of Rio Tinto plc shares using a stock transfer form are subject to stamp duty at a rate of 0.5% of the consideration on transactions over £1,000 (rounded up to the nearest £5). Conversions of Rio Tinto plc shares into Rio Tinto plc ADSs will be subject to additional stamp duty or SDRT at a rate of 1.5% of the amount or value of the consideration given or, in certain circumstances, the value of the shares, on all transfers to the depositary or its nominee.

Australian taxation of shareholdings in Rio Tinto Limited

Taxation of dividends

US holders are not normally liable to Australian withholding tax on dividends paid by Rio Tinto Limited because such dividends are normally fully franked under the Australian dividend imputation system, meaning that they are paid out of income that has borne Australian income tax. Any unfranked dividends would suffer Australian withholding tax which under the Australian income tax convention is limited to 15 per cent of the gross dividend.

Capital gains

US holders are not normally subject to any Australian tax on the disposal of Rio Tinto Limited ADSs or shares unless they have been used in carrying on a trade or business wholly or partly through a permanent establishment in Australia, or the gain is in the nature of income sourced in Australia.

Gift, estate and inheritance tax

Australia does not impose any gift, estate or inheritance taxes in relation to gifts of shares or upon the death of a shareholder.

Stamp duty

An issue or transfer of Rio Tinto Limited shares does not require the payment of Australian stamp duty.

US federal income tax

In general, taking into account the earlier assumptions that each obligation of the Deposit Agreement and any related agreement will be performed according to its terms, for US federal income tax purposes, if you hold ADRs evidencing ADSs, you will be treated as the owner of the shares represented by those ADRs. Exchanges of shares for ADRs, and ADRs for shares, generally will not be subject to US federal income tax.




Taxation of dividends

Under the US federal income tax laws, and subject to the Passive Foreign Investment Company (PFIC) Rulesrules discussed below, if you are a US holder, the gross amount of any distribution the Groupa company pays out of its current or accumulated earnings and profits (as determined for US federal income tax purposes) is subject to US federal income taxation as dividend income. The dividend will not be eligible for the dividends-received deduction generally allowed to US corporations in respect of dividends received from certain other US corporations. Distributions in excess of current and accumulated earnings and profits, as determined for US federal income tax purposes, will be treated as a non-taxable return of capital to the extent of your tax basis in the sharesGroup’s ADSs or ADSsshares and thereafter as capital gain. Rio TintoThe Group does not maintain calculations of its earnings and profits in accordance with US federal income tax accounting principles. US holders should therefore assume that any distributions thethat a Group member pays with respect to the Group’s ADSs or Shares will be reported as ordinary dividend income.

Dividends paid to a non-corporate US holder generally may be taxable at the reduced rate normally applicable to long-term capital gains provided the shares are readily tradable on an established securities market in the United States or the company paying the dividend qualifies for the benefits of an income tax treaty between the


United States and the relevant jurisdiction and certain other requirements are met.met (including certain holding period requirements). Rio Tinto plc ADSs are traded on the NYSE. Rio Tinto Limited believes it qualifies for the benefits of the convention between the US and Australia. A US holder may be eligible for this reduced rate only if it has held the shares or ADSs for more than 60 days during the 121-day period beginning 60 days before the ex-dividend date.

The dividend is taxable to you when you, in the case of shares, or the depositary, in the case of ADSs, receive the dividend, actually or constructively. The amount of the dividend distribution that you must include in your income as a US holder will be the US dollar value of the non-US dollar payments made, determined at the spot UK pound/US dollar rate (in the case of Rio Tinto plc) or the spot Australian dollar/US dollar rate (in the case of Rio Tinto Limited) on the date the dividend distribution is includible in your income, regardless of whether the payment is in fact converted into US dollars. Generally, any gain or loss resulting from currency exchange fluctuations during the period from the date you include the dividend payment in income to the date you convert the payment into US dollars will be treated as ordinary income or loss and will not be eligible for the reduced tax rate normally applicable to capital gains. The gain or loss generally will be income or loss from sources within the US for foreign tax credit limitation purposes.

You must include any Australian tax withheld from the dividend payment in this gross amount even though you do not in fact receive it. Subject to certain limitations, any Australian tax withheld in accordance with the convention between the US and Australia and paid over to Australia will be creditable or deductible against your US federal income tax liability. For foreign tax credit purposes, dividends will generally be income from sources outside the US and will, depending on your circumstances, generally be either “passive” or “general” income which, in either case, is treated separately from other types of income for purposes of computing the foreign tax credit allowable to you. The rules regarding foreign tax credits are complex and US holders should consult their own tax advisors regarding the outstanding and calculation of foreign tax credits and the application of the foreign tax credit rules to their particular situation.

Taxation of capital gains

Subject to the PFIC Rulesrules discussed below, if you are a US holder and you sell or otherwise dispose of the Group’s ADSs or shares, you will recognise a capital gain or loss for US federal income tax purposes equal to the difference between the US dollar value of the amount that you realise and your tax basis, determined in US dollars, in your shares or ADSs. The capital gain of a non-corporate US holder is generally taxed at preferential rates where the holder has a holding period greater than one year. The gain or loss will generally be income or loss from sources within the US for foreign tax credit limitation purposes.

US holders should consult their own tax advisers about how to account for proceeds received on the sale or other disposition of the Group’s ADSs or shares that are not paid in US dollars.

Passive Foreign Investment Company Rules

We believe that the Group’s sharesADSs or ADSsshares should not be treated as stock of a PFIC for US federal income tax purposes for the 20172019 taxable year, but this conclusion is a factual determination that is made annually and thus may be subject to change. If we were to be treated as a PFIC, US holders generally would be required (i) to pay a special addition to US tax on certain distributions and gains on sale of sharesthe Group’s ADSs or ADSs,shares, and (ii) to pay tax on any gain from the sale of sharesthe Group’s ADSs or ADSsshares at ordinary income (rather than capital gains) rates in addition to paying the special addition to tax on this gain. Additionally, dividends that you receive from us will not be eligible for the reduced rate of tax described above under “Taxation of dividends.” US holders should consult their own tax advisors regarding the potential application of the PFIC rules.



Backup Withholding and Information Reporting

The proceeds of a sale or other disposition, as well as dividends and other proceeds, with respect to sharesthe Group’s ADSs or ADSsshares by a US paying agent or other US intermediary will be reported to the IRSUS Internal Revenue Service and to the US holder as may be required under applicable regulations. Backup withholding may apply to these payments if the US holder fails to provide an accurate taxpayer identification number or certification of exempt status or fails to comply with applicable certification requirements. Certain US holders are not subject to backup withholding. US holders should consult their tax advisers about these rules and any other reporting obligations that may apply to the ownership or disposition of sharesthe Group’s ADSs or ADSs,shares, including requirements related to the holding of certain foreign financial assets.

Report of Independent Registered Public Accounting Firms


To the Boards of Directors and Shareholders of Rio Tinto plc and Rio Tinto Limited



Opinions on the Financial Statements and Internal Control over Financial Reporting


We have audited the accompanying consolidated balance sheets of the Rio Tinto Group (comprising Rio Tinto plc and Rio Tinto Limited and their respective subsidiaries) as of 31 December 20172019 and 2016,2018, and the related Group income statement, the Group statement of comprehensive income, the Group cash flow statement and the Group statement of changes in equity for each of the three years in the period ended 31 December 2017,2019, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Group’s internal control over financial reporting as of 31 December 2017,2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).


In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Group as of 31 December 20172019 and 2016,2018, and the results of its operations and its cash flows for each of the three years in the period ended 31 December 20172019 in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board and in conformity with International Financial Reporting Standards as adopted by the European Union. Also in our opinion, the Rio Tinto Group maintained, in all material respects, effective internal control over financial reporting as of 31 December 2017,2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.


Basis for Opinions


The Rio Tinto Group’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on the Group’s consolidated financial statements and on the Rio Tinto Group's internal control over financial reporting based on our audits. We are public accounting firms registered with the Public Company Accounting Oversight Board (United States) ("PCAOB")(PCAOB) and are required to be independent with respect to the Group in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.


We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.


Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.


Definition and Limitations of Internal Control over Financial Reporting


A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of


records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting



principles, and that receipts and expenditures of the company are being made only in accordance with authorisations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorised acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.


Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.


Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (i) relate to accounts or disclosures that are material to the consolidated financial statements; and (ii) involved especially challenging, subjective, or complex judgements by us. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Assessment of the recoverable amount of the Oyu Tolgoi and Yarwun cash-generating units

As described in Notes 1 and 6 to the consolidated financial statements, management identified impairment triggers at each of its Oyu Tolgoi and Yarwun cash-generating units (“CGUs”). Following assessment of recoverable amount based on a fair value less costs of disposal (“FVLCD”) methodology, it identified that pre-tax impairment losses had been incurred of $2,240m at Oyu Tolgoi and $1,138m at Yarwun. The determination of recoverable amount required judgement and estimation on the part of management. For Oyu Tolgoi, the critical assumptions include development capital, scheduling, production, discount rate and commodity price assumptions. For Yarwun, the critical assumptions are the alumina price and the discount rate.

The principal considerations for our determination that performing procedures relating to the assessment of the recoverable amounts of these CGUs is a critical audit matter are the significant judgement and estimation required by management in making these assessments and the complexity of the valuations, which in turn led to a high degree of subjectivity and effort in performing procedures relating to the critical assumptions used. In addition, the audit effort involved the use of professionals with specialised skill and knowledge to assist in performing these procedures and evaluating the audit evidence obtained.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to impairment, specifically controls in relation to the identification of impairment triggers and determination of recoverable amount, and over key assumptions in valuation models such as commodity prices and discount rates. These procedures included, among others, (i) testing management’s process for developing the recoverable amount estimate; (ii) evaluating the appropriateness of the FVLCD methodology; (iii) testing the completeness, accuracy and relevance of underlying data used in the estimate; and (iv) evaluating the significant assumptions used by management, including development capital, scheduling, production, discount rate and commodity price assumptions. Evaluating management’s assumptions involved evaluating whether the assumptions used by management were reasonable considering; (i) the current and past performance of the CGUs; (ii) the consistency with external market and industry data; and (iii) whether these assumptions were consistent with evidence obtained in other areas of the audit. Professionals with specialised skill and knowledge were used to assist in the evaluation of the Group’s FVLCD model and certain significant assumptions, including the discount rate.

Provisions for close-down, restoration and environmental obligations at Rio Tinto Kennecott

As described in Notes 1 and 26 to the consolidated financial statements, there has been an increase in closure and environmental liabilities at Rio Tinto Kennecott of $444m. The most significant component of the increase in this provision is an increased expected cost of closure, identified by management in preparing its closure study, which is ongoing. The estimate required significant judgement in relation to the closure timeframe, the length of any post-closure monitoring period and the discount rate.



The principal considerations for our determination that performing procedures relating to provisions for close-down, restoration and environmental obligations at Rio Tinto Kennecott is a critical audit matter are the significant judgement applied by management in relation to the closure timeframe, the length of any post-closure monitoring period and the discount rate. This in turn led to a high degree of subjectivity and judgement in applying audit procedures to the matter and the audit effort involved the use of professionals with specialised skill and knowledge to assist in evaluating the audit evidence obtained.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the estimation of the closure provision, including controls over the calculation of the provision. These procedures also included, among others; (i) testing the existence of legal and/or constructive obligations with respect to the closure provision and considering the intended method of restoration and rehabilitation and associated cost estimate; (ii) testing the cost estimates prepared by management; (iii) testing the mathematical accuracy of management’s calculations and assessing the appropriateness of the discount rate; (iv) reading minutes of the meetings of management’s Investment Committee and the latest available papers detailing findings from the closure study as presented to that Committee; and (v) considering whether the updates in the provision reflected changes to previous estimates or the correction of prior period errors. Professionals with specialised skill and knowledge were used to assist in the evaluation of the cost estimate and the discount rate.

Provisions for uncertain tax positions associated with transfer pricing of certain transactions with the Group’s commercial centre in Singapore

As described in Notes 1 and 9 to the consolidated financial statements, the Group establishes provisions based on its interpretation of tax law and its assessment of the weighted average or most likely amount of the liability, as appropriate. The assessment associated with the provision related to transfer pricing of certain transactions with the Group’s commercial centre in Singapore is subjective and required judgement in determining the possible outcomes, their relative likelihoods, and the quantum of the liability in each of those scenarios.

The principal considerations for our determination that performing procedures relating to provisions for uncertain tax positions associated with transfer pricing of certain transactions with the Group’s commercial centre in Singapore is a critical audit matter are that there was significant judgement by management when determining uncertain tax positions, including a high degree of estimation uncertainty. This in turn led to a high degree of auditor judgement, effort, and subjectivity in performing procedures to evaluate the accurate measurement of uncertain tax positions. Also, the evaluation of audit evidence available to support the tax liabilities for uncertain tax positions is complex as the nature of the evidence is often highly subjective, and the audit effort involved the use of professionals with specialised skill and knowledge to assist in evaluating the audit evidence obtained.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the completeness and accuracy of the provision to be recorded for uncertain tax positions. These procedures also included, among others; (i) evaluating the latest available correspondence between management and the relevant tax authorities to assess the appropriateness of the assumptions used by management in calculating the provisions; (ii) testing the mathematical accuracy of management’s provision calculations and agreeing relevant input data to supporting records; and (iii) involving professionals with specialised skill and knowledge to assist in evaluating the assumptions and calculations on which the provision has been determined.
