3.D Risk factors

Risk management

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

Risk management framework

Rio Tintos risk management framework reflects our belief that managing risk effectively is an integral part of how the Group creates value, and
fundamental to the Groups business success. The responsibility for identifying and managing risks lies with all of Rio Tintos managers and business leaders. They operate within the Group-wide framework to manage risks within understood
thresholds.

The framework includes clearly defined oversight responsibilities for the board and the Executive Committee, who are supported by the Risk
Management Committee (an executive management committee chaired by the chief executive) and central support functions including Group Risk and Group Audit & Assurance, 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 the operations.
|- | -----------------------------------------------------------



| | Second line of defence: control of risk by central support functions and the Risk Management Committee.
|- | -------------------------------------------------------------------------------------------------------



| | Third line of defence: assurance of systems of internal control by Group Audit & Assurance.
|- | -------------------------------------------------------------------------------------------

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

Approach

The Groups
approach to risk management, underpinned by the Risk policy and standard, is aimed at embedding a risk-aware culture in all decision-making, and a commitment to managing risk in a proactive and effective manner. This includes the early
identification and evaluation of risks, the management and mitigation of risks before they materialise, and dealing with them effectively in the event they do materialise. Accountability for risk management is clear throughout the Group and is a key
performance area of 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 management team and ultimately to the board where appropriate. Group Risk also supports the Risk Management Committee in
its review of risk.

##### Table of Contents

The process for identifying, evaluating and managing the material business risks is designed to manage, rather
than eliminate, risk and where appropriate accept risk to generate returns. Certain risks, for example natural disasters, cannot be managed using internal controls. Such major risks are transferred to third parties in the international insurance
markets, to the extent considered appropriate or possible.

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

Principal risks and uncertainties

The principal risks and uncertainties outlined in this section reflect the risks that could materially affect Rio Tinto or its ability to meet its strategic
objectives, either directly or by triggering a succession of events that in aggregate become material to the Group. Rio Tintos business units and functions assess the potential economic and non-economic consequences of their respective risks
using the framework defined by the Groups Risk policy and standard. Once identified, each principal risk or uncertainty is reviewed and monitored by the relevant internal experts and by the Risk Management Committee, the relevant board
committees and the board.

There may be additional risks unknown to Rio Tinto and other risks currently not believed to be material which could turn out
to be material. In previous years the Group has reported risks related to climate change, community disputes, discount rates, short-term cash generation initiatives, technology and innovation, supply chain and third party exposure, industrial
relations, availability of skilled resources, and closure. The Group remains exposed to these risks but does not consider them to be principal risks currently (as defined below). Therefore they are not discussed in detail in this section. A number
of them are, however, referred to in the sustainable development section of the Annual Report 2015 on pages 22 to 28.

The principal risks and
uncertainties listed in this section may materialise individually, simultaneously or in combination and could significantly threaten the Group in the following respects:

Business model

The basis on which
the Group generates or preserves value over the longer term, given its market positioning as a global diversified mining and processing business.

Future performance

The Groups ability to deliver its financial plan in the short to medium term.

Solvency

The Groups ability
to maintain an appropriate capital structure and to meet its financial liabilities in full.

Liquidity

The Groups ability to meet its financial liabilities as they fall due.

Health, safety, environment and communities (HSEC)

The Groups ability to send our employees and contractors home safe and healthy every day and work with our communities and partners to achieve our
sustainable development goals.

Group reputation

The Groups ability to maintain investor confidence and our social licence to operate.

|Commodity
prices, driven by demand and supply for the Groups products, vary outside of expectations over time. Exchange rate variations and
geopolitical issues may offset or exacerbate this risk.  External risk |  | Falling commodity prices, or adverse exchange rate movements, reduce cash flow, limiting profitability and dividend payments. These may trigger impairments
and/or impact rating agency metrics. Extended subdued prices may reflect a longer-term fall in demand for the Groups products, and consequent reduced revenue streams may limit investment opportunities.

activity incurs transaction costs that cannot be recouped, or result in value destruction by realising less than planned value for divestments or paying more than fair value for acquisitions. This could result in unforeseen pressure on the
Groups cash position or reduce the Groups ability to expand operations. The Group may also be liable for the past acts, omissions or liabilities of assets it has acquired that were unforeseen or greater than anticipated at the time of
acquisition. The Group may also face liabilities for divested entities if the buyer fails to honour commitments or the Group agrees to retain certain liabilities.

chemicals, gases, vehicles and machinery, extreme natural environments, endangered flora or fauna, areas of cultural heritage significance, water supply stress and climate change.

|The success of the Groups exploration activity
may vary. In addition, estimates of ore reserves are based on uncertain assumptions that, if changed, could result in the need to restate ore reserves. 
External risk
Internal risk |  | A failure to discover new orebodies could undermine future growth
prospects.  The risk that new information comes to light or operating conditions change
means that the economic viability of some ore reserves can change and thus the reserves need to be restated downwards. As a result, projects may be less successful and of shorter duration than initially anticipated, and/or the asset value may be
impaired.

External risk
Internal risk                                    |  | Decreased productivity or 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 such as accidental or malicious actions.
   Natural disasters such as
earthquakes, subsidence, drought, flood, fire, storm and climate change can impact mines, smelters, refineries and infrastructure installations. 
Any of these events could result in a significant HSEC incident, an interruption to operations, or the inability to deliver products and a commercial
loss.

partnerships and third parties influence the Groups supply, operations and reputation. The Groups ability to control the actions of these parties varies. 
External risk               |  | Joint venture partners may
hinder growth by not agreeing to support investment decisions. For non-managed operations, controlling partners may take action contrary to the Groups interests or standards and policies, resulting in adverse impact to health and safety,
performance, reputation or legal liability.

number of jurisdictions, which exposes the Group to a wide range of economic, political and regulatory risks. 
External risk                           |  | Adverse actions by governments and others can result in
operational/project delays or loss of licence to operate. Other potential consequences can include expropriation, nationalisation, changes in taxation, as well as currency and foreign investment restrictions. Legal frameworks with respect to
policies such as energy, climate change, mineral law and taxation may also change in a way that increases costs.

rules, anti-corruption legislation, sanctions or human rights violations or other inappropriate business conduct. 
A serious allegation or formal investigation by regulatory authorities (regardless of ultimate decision) could result in a loss in share price value, and/or
loss of business. Other consequences could include the criminal prosecution of individuals, imprisonment and/or personal fines, and reputational damage to the Group. There may also be considerable cost and disruption in responding to allegations or
investigations and taking remedial action.

Additional Financial Information

2015 financial
performance compared with 2014

In order to provide additional insight into the performance of our business, Rio Tinto presents underlying earnings,
which is defined in financial statements Note 2 Operating segments on pages 125 to 127 of the Annual Report 2015.

2015 underlying earnings of
US$4,540 million and net losses of US$866 million were US$4,765 million below and US$7,393 million below the comparable measures for the previous year respectively (2014 underlying earnings of US$9,305 million and net earnings of US$6,527 million
were US$912 million below and US$2,862 million above 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 (loss)/profit for the period reported in the income statement should also include (losses)/earnings attributable to non-controlling interests in subsidiaries. Underlying earnings is reconciled to net
(losses)/earnings in the table below, which also lists the principal factors driving the movement in underlying earnings between periods.

Prices

The
effect of price movements on all major commodities in 2015 was to decrease underlying earnings by US$7,695 million compared with 2014. The Platts price for 62 per cent iron Pilbara fines was 43 per cent lower on average compared with 2014 while hard
coking coal benchmark prices were 19 per cent lower on average and thermal coal spot prices averaged 16 per cent lower. Average copper and gold prices were down 20 and eight per cent respectively, while London Metal Exchange (LME) aluminium prices
averaged 11 per cent lower.

Exchange rates

Compared
with 2014, the US dollar, on average in 2015, was stronger by 14 per cent against the Canadian dollar and South African rand and by 16 per cent against the Australian dollar. The effect of all currency movements was to increase underlying
earnings relative to 2014 by US$2,007 million.

Volumes

Volumes improved earnings by US$132 million compared with 2014. Increased volumes were achieved primarily in iron ore, following the increase in capacity at
the Pilbara ports and mines, and in bauxite, from record production at Weipa and the ramp-up at Gove. These offset volume declines in copper, mainly at Rio Tinto Kennecott where the focus on de-weighting and de-watering the east wall of Bingham
Canyon continued, and in titanium dioxide feedstocks, where production was aligned with market demand.

Energy

Lower input energy prices during the period improved underlying earnings by US$359 million compared with 2014 mainly related to oil, where the price fell
approximately 50 per cent year on year to an average US$52 per barrel during 2015.

Cash costs, exploration and evaluation

Rio Tinto made further strong progress on its cost reduction programme and had, as of 31 December 2015, achieved US$6.2 billion pre-tax (US$4.3
billion post-tax) in total operating cash cost improvements and reductions in exploration and evaluation expenditure compared with the 2012 base.

In
2015, the Group realised US$1.3 billion pre-tax (US$1.0 billion post-tax) in operating cash cost savings and reductions in exploration and evaluation expenditure. This was in addition to the US$4.8 billion pre-tax (US$3.3 billion post-tax) achieved
in aggregate in 2013 and 2014.

The Group continued to refine its exploration and evaluation expenditure, building on the savings achieved in 2014 whilst
progressing the highest priority projects. In 2015, approximately six per cent of this expenditure was incurred by Iron Ore, two per cent by Aluminium, 38 per US cent by Copper & Coal, 23 per cent by Diamonds & Minerals and the remainder by
central exploration on greenfield programmes.

Tax / non-cash / interest / other

The 2015 effective corporate income tax rate on underlying earnings, excluding equity accounted units, was 27 per cent compared with 28 per cent in 2014. The
decreased rate was principally attributable to the absence of the Australian Minerals Resource Rent Tax (MRRT) which was repealed in the second half of 2014.

The Group interest charge (net of tax) of US$389 million increased by US$228 million compared with 2014, following completion of some major capital
projects in the first half of 2015. Interest is capitalised during the construction period. In 2015, US$254 million of interest was capitalised, compared with US$470 million in 2014.

Prices

The effect of price movements on all major commodities in 2014 was to decrease underlying earnings by US$4,146 million compared with 2013. The average Platts
price for 62 per cent iron Pilbara fines was 31 per cent lower compared with 2013, and hard coking coal benchmark prices 21 per cent lower, and thermal coal spot prices 17 per cent lower. Average copper and gold prices were down six and ten per cent
respectively, whilst London Metal Exchange (LME) aluminium prices averaged one per cent higher.

Exchange rates

Compared with 2013, the US dollar, on average in 2014, was stronger by seven per cent against both the Australian and Canadian dollars and by 13 per cent
against the South African rand. The effect of all currency movements was to increase underlying earnings relative to 2013 by US$691 million.

Volumes

Volumes enhanced earnings by US$1,431 million compared with 2013. These were achieved primarily in iron ore, where, for a second consecutive year, a new annual
sales volume record was achieved following the increase in capacity at the Pilbara ports and mines, combined with productivity improvements. Volumes also rose in copper, following the recovery at Rio Tinto Kennecott from the Bingham Canyon pit wall
slide, in addition to higher ore grades and increased throughput, and at Oyu Tolgoi as shipments outpaced production.

Cash costs, exploration and
evaluation

Rio Tinto made further strong progress on its cost reduction programme and had, as at 31 December 2014, achieved US$4.8 billion
pre-tax (US$3.3 billion post-tax) in total operating cash cost improvements and reductions in exploration and evaluation expenditure compared with the 2012 base.

In 2014, the Group realised US$1.2 billion post tax in operating cash cost savings and reductions in exploration and evaluation spend. This was in addition to
the US$2.1 billion post-tax achieved in 2013.

Tax / non-cash / interest / other

The 2014 effective corporate income tax rate on underlying earnings, excluding equity accounted units, was 28 per cent compared with 35 per cent in 2013. The
decreased rate was primarily attributable to the repeal of MRRT in the second half of 2014 and the absence of prior year tax provisions.

The Group
interest charge was US$81 million lower than in 2013, mainly reflecting the reduction in net debt during 2014.

In 2013, there was a US$128 million
charge to earnings from an iron ore royalty payable to joint venture partners following a court decision. There was no such charge in 2014.

2015

Total impairment charges of US$1,802 million (post-tax) were recognised in 2015. On 26 May 2014, Rio Tinto and its Simandou 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 are currently finalising
an integrated Bankable Feasibility Study (BFS) for the mine, port and infrastructure elements of the project, which is 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, the Group has determined that it would be 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. Total impairment charge recognised was a non-cash charge of US$262 million (net of non-controlling interest 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 & Coal 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.

##### Table of Contents

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 has been recognised for the remediation of legacy properties, including the Holden Mine in
Washington State.

2014

Impairment charges of US$1,187 million (net of tax and non-controlling interests) were recognised in 2014 and related to the Groups aluminium business,
US$840 million, and the Groups copper businesses, US$347 million.

The Groups copper business impairment charge resulted from a review of the
investment case for the Molybdenum Autoclave Process project in Utah, USA which concluded that the project, which had been on care and maintenance since early 2013, would be terminated. The recoverable amount was determined based on anticipated net
disposal proceeds. As a result, a post-tax impairment charge of US$347 million was recorded against property, plant and equipment.

During the first half
of 2014, further revisions to future capital required to complete the modernisation project at Kitimat in British Columbia, and related impacts on the project, led to a reduction in the recoverable value of the Kitimat cash-generating unit.
Additional capital of US$1.5 billion was approved by the Board in August 2014, taking the total approved capital cost of the project to US$4.8 billion. The reduction in the recoverable amount resulted in a post-tax impairment charge of US$800
million to property, plant and equipment. Other post-tax impairment charges during 2014, related to the Groups Aluminium business, were US$40 million.

The above impairment charges were largely offset by the reversal of previously booked impairments on other non-current assets in the Groups aluminium
business, due to significant cost improvements and high regional and product premiums. This resulted in a post-tax impairment reversal of US$460 million recorded against the property, plant and equipment of Tomago, Bell Bay and Gladstone Power
Station and a post-tax impairment reversal of US$589 million relating to Boyne Smelters recorded against investments in equity accounted units. The recoverable amount of the assets is greater than the amount at which these assets would have been
carried, net of depreciation, had no impairment loss been recognised in prior periods and therefore the impairment reversal is based on the latter amount.

Net losses on disposal and consolidation of interests in businesses during 2014 mainly related to the Groups divestment of Rio Tinto Coal Mozambique,
the Clermont Joint Venture and the transfer of Alucam to the Government of Cameroon.

Non-cash exchange and derivative losses of US$1,850 million arose
primarily on US dollar debt in non-US dollar functional currency Group companies, and on intragroup balances.

The remaining MRRT starting base deferred
tax asset was derecognised on repeal of the tax in Australia, effective 30 September 2014.

A gain of US$356 million net of tax was recognised
on the disposal of the Groups St Jamess Square properties in London, UK.

2013

Total impairment charges of US$3,428 million (net of tax and non-controlling interests) were recognised in 2013, of which US$2,125 million related to the
Groups copper and coal businesses. This included a charge of US$1,565 million related to the impairment of certain assets of Turquoise Hill (including Oyu Tolgoi). On 29 July 2013, Rio Tinto announced that funding and work on the
underground development would be delayed pending resolution of outstanding shareholder issues, including finalising project finance. The consequent impact of updates to timing of revenues and expenditure resulted in the carrying value being higher
than fair value less costs of disposal (FVLCD).

##### Table of Contents

Impairments to the Groups copper businesses also included adjustments to reduce the carrying value of the
Eagle nickel-copper project to FVLCD prior to divestment on 17 July 2013.

A post-tax impairment charge of US$470 million relating to Rio Tinto
Coal Mozambique (RTCM) was recognised. An assessment of FVLCD derived from future cash flows, which included a reassessment of the development plan and review of the discount rate and associated country risk premium, resulted in the recoverable
value being below carrying value. Other impairments included the impact of medium and long-term coking and thermal coal prices on non-cash fair value acquisition adjustments to undeveloped projects at SouthGobi Resources, and adjustment to the
carrying value of Inova Resources, which was sold on 1 November 2013.

In addition, there was a post-tax impairment of US$1,293 million relating
to the Groups aluminium businesses. This included US$555 million for the Gove refinery, following an announcement on 29 November 2013 to suspend alumina production and focus on the bauxite operation. As a result of this decision, the
timing and scope of site restoration and environmental rehabilitation cash flows were revised, together with the write-off of operating assets not fully depreciated. The remaining post-tax charge of US$738 million related to the Groups
Canadian aluminium operations, primarily at Kitimat in British Columbia, resulting from a change in assumptions about future capital required to complete the modernisation project, which diminished the value of the associated intangible assets, and
another site closure within the Aluminium portfolio.

Net gains on disposal of interests in businesses during 2013 mainly related to the Groups
divestment of its remaining interest in Constellium (formerly Alcan Engineered Products) and the Northparkes mine.

Non-cash exchange and derivative losses
of US$2,731 million arose primarily on US dollar debt in non-US dollar functional currency Group companies, and on intragroup balances.

Rio Tinto
Kennecotts Bingham Canyon mine experienced a slide along a geological fault line of its north-eastern wall in April 2013. Charges relating to the slide, which were excluded from underlying earnings, primarily comprised the write-off of
certain deferred stripping assets and damaged equipment. Adjustments for settlement of insurance claims were made to the amount excluded from underlying earnings, and were forecast to continue as insurance claims settled.

Adjustments in relation to Clermont and Blair Athol arose following reclassification to disposal groups held for sale, and reflected contractual obligations
for product sales and funding of closure activities, which would remain with the Group following completion of the divestments.

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 194 to 198 of the Annual Report 2015.

Iron Ore

2015 sales revenue compared with 2014

Higher sales volumes (approximately 11 per cent) in the Pilbara partially mitigated the impact of lower iron ore prices, down 43 per cent on average year on
year. In 2015, approximately 22 per cent of sales were priced with reference to a quarterly average index set at the prior quarters average lagged by one month. The remainder was sold via pricing mechanisms priced closer to the index price at
the time of shipment, such as current quarter average, current month average or spot index prices. Index prices are adjusted for product characteristics and iron and moisture content.

2014 sales revenue compared with 2013

Record sales volumes in the Pilbara for a second year partially mitigated the impact of lower iron ore prices, down 30 per cent on average year on year. In
2014, approximately 25 per cent of sales were priced with reference to a quarterly average index set at the prior quarters average lagged by one month. The remainder was sold via pricing mechanisms priced closer to the index price at the time
of shipment, such as current quarter average, current month average or spot index prices. Index prices are adjusted for product characteristics and iron and moisture content.

Aluminium

2015 sales revenue
compared with 2014

The Aluminium product groups sales revenues are from aluminium and related products such as alumina and bauxite.

##### Table of Contents

The decline in prices was the main driver of the 17 per cent drop in revenues compared with 2014. The 2015 cash
LME aluminium price averaged US$1,661 per tonne, a decrease of 11 per cent on 2014. Market premia across all regions fell an average of 36 per cent in 2015, down from US$404 per tonne in 2014 to US$257 per tonne in 2015.

Bauxite prices were stable in 2015, underpinned by growing import demand from China. Rio Tintos share of third party bauxite sales increased by 14 per
cent in 2015 compared with 2014.

2014 sales revenue compared with 2013

A one per cent increase in LME prices and stronger regional and product premia were not sufficient to offset the impact of reduced sales volumes of bauxite and
aluminium compared with 2013, resulting in a three percent reduction in sales revenue. The reduction in aluminium sales volumes was mainly due to the closure of the Shawinigan smelter in December 2013 and the divestment of the Søral and
Alucam smelters during 2014.

Copper & Coal

2015 sales revenue compared with 2014

Gross sales revenue decreased by 23 per cent in 2015 compared with 2014. Average prices
in 2015 were lower than 2014 for the Copper & Coal product group commodities.

Copper price declined 20 per cent to 249 US cents per pound and gold
decreased 8 per cent to US$1,160 per ounce, which were the main drivers for the decline in gross sales revenue from copper operations (down 22 per cent compared with 2014).

At 31 December 2015, the Group had an estimated 252 million pounds of copper sales (2014: 331 million pounds) that were provisionally priced at 217
US cents per pound (2014: 288 US cents per pound). The final price of these sales will be determined during the first half of 2016.

There was a decline
in gross sales revenue from coal operations of 24 per cent compared with 2014. Thermal and coking coal prices declined further in 2015, averaging US$62 and US$102 per tonne respectively. In addition to lower thermal and coking coal prices,
there was also a decline in sales volumes mainly due to the divestment of the Clermont mine in May 2014.

A significant proportion of Rio Tintos
coal production is sold under long-term contracts. In Australia, the prices applying to sales under the long-term contracts are generally renegotiated annually for thermal coal, but prices are fixed at different times of the year and on a variety of
bases. Coking coal prices for 2015 have been negotiated on a quarterly basis consistent with 2014. For these reasons, average realised prices will not necessarily reflect the movements in any of the publicly available prices.

2014 sales revenue compared with 2013

Gross sales revenue decreased by five per cent in 2014 compared with 2013, as a result of the increase in copper operations (six percent increase year-on-year)
offset by reductions from coal operations (18.5 per cent year-on-year).

The six per cent increase in copper operations gross sales revenue compared with
2013 arose from increased sales volumes, primarily attributable to a full year of production at Oyu Tolgoi, which was partially offset by a seven per cent decline in average copper prices and an 11 per cent decline in the average gold price during
the period.

The 18.5 per cent decline in coal operations gross sales revenue was predominantly attributable to lower prices, with 21 per cent and 17 per
cent reductions in the average coking coal benchmark and thermal coal prices respectively. Price reductions were partially offset by higher sales volumes at Kestrel and Hail Creek, offset by the loss of tonnes from Clermont with the divestment
completed on 29 May 2014.

Diamonds & Minerals

2015 sales revenue compared with 2014

Gross sales revenues decreased by 23 per cent compared with 2014, with lower revenues driven by lower prices and a reduction in sales volumes. Sales volumes
were lower across most products, including the impact of softer markets, most notably in titanium dioxide feedstocks. In addition, prices for Rio Tinto Iron & Titaniums metallic co-products fell in response to market trends and
titanium dioxide feedstock prices remained under pressure as the industry continued to absorb inventories.

Sales volumes of diamonds were higher due to
the ramp up of the Argyle underground mine, but industry rough diamond prices were weaker, driven by lower demand from India and China, higher rough diamond and polished diamond inventory and lower trade manufacturer margins. Diamond prices
realised by Rio Tinto depend on the size and quality of diamonds in the product mix.

The uranium spot price index ended the year 4 per cent below 2014 at
US$34.23 per pound, while the long-term price indicators lost 11 per cent to end the year at US$44.00 per pound. Rio Tinto Uranium also sells predominantly on a longer-term contract basis.

Sales volumes of all products will vary during the year and the timing of shipments will also result in differences between average realised prices and
published prices.

2014 sales revenue compared with 2013

Gross sales revenues decreased by seven per cent compared with 2013. Excluding the impact of Uranium, gross sales revenues decreased by one per cent,
mainly driven by lower prices for titanium dioxide feedstocks, borates and zircon, and a decline in volume of diamond sales which were partially offset by higher realised prices on diamonds, and higher sales volumes of titanium dioxide feedstocks,
borates and zircon.

Diamond prices realised by Rio Tinto depend on the size and quality of diamonds in the product mix. Gross sales revenues from Uranium
declined 32 per cent compared with 2013. The uranium spot price index ended the year three per cent above 2013 at US$35.50 per pound, while the long-term price indicators lost one per cent to end the year at US$49.50 per pound.

Cash flow

2015 compared with 2014

A full consolidated cash flow statement is contained in the financial statements on page 109 of the Annual Report 2015.

Net cash generated from operating activities of US$9.4 billion was 34 per cent lower than 2014, mainly due to the impact of lower prices, reflecting cash cost
improvements and lower tax payments in line with lower profits.

Total working capital cash inflows of US$1.5 billion in 2015 arose from continued efforts
to reduce inventories and receivables, which were partly offset by a reduction in payables, mostly from actions taken to reduce capital and operating expenditures during the year.

Purchases of property, plant and equipment and intangible assets declined by US$3.5 billion or 43 per cent to US$4.7 billion in 2015. Major capital projects
included the completion of the expansion of the Pilbara iron ore infrastructure and the modernisation and expansion of the Kitimat aluminium smelter in British Columbia, where first metal was poured in June 2015.

Dividends paid in 2015 of US$4.1 billion reflected the increase in the final 2014 dividend paid in April 2015 and the 2015 interim dividend paid in
September 2015. Share repurchases totalled US$2.0 billion in 2015.

##### Table of Contents

2014 compared with 2013

Net cash generated from operating activities was US$14.3 billion, five per cent lower than 2013, reflecting the negative impact of lower prices partially
offset by the positive impact of higher volumes, cash costs improvements and favourable current trade working capital movements.

Purchase of property,
plant and equipment and intangible assets declined by US$4.8 billion or 37 per cent to US$8.2 billion in 2014. This was driven by the completion of five major capital projects during 2013 and continued capital discipline.

Net proceeds from disposals of subsidiaries, joint ventures and associates totalled US$0.9 billion in 2014, primarily reflecting the sale of the Groups
interests in the Clermont Joint Venture and Rio Tinto Coal Mozambique.

Other investing cash flows resulted in an improvement of US$647 million, mainly
due to the disposal of the Groups properties at St Jamess Square.

Dividends paid in 2014 of US$3.7 billion reflect the 12 per cent increase
to the 2013 dividends paid.

Repayments of borrowings increased from US$1.8 billion to US$3.5 billion during 2014.

Balance sheet at 31 December 2015

Net debt
increased from US$12.5 billion at 31 December 2014 to US$13.8 billion at 31 December 2015, with free cash flow partly funding the US$2.0 billion share buy-back. Net debt as at 31 December 2015 was made up principally
from adjusted total borrowing (as defined in financial statements Note 24 Consolidated net debt of the Annual Report 2015) of US$23.1 billion, offset by US$9.4 billion in cash and cash equivalents. Net debt to total capital (gearing
ratio) was 24 per cent at 31 December 2015 (31 December 2014: 19 per cent). The increase in the gearing ratio was mainly driven by the US$10.5 billion decline in shareholders equity from 31 December 2014 to
31 December 2015, which was largely attributable to weaker Australian and Canadian currencies along with the share buy-back and dividend payments.

Adjusted total borrowings at 31 December 2015 were US$23.1 billion. The weighted average cost of total borrowings was approximately 3.5 per cent and
the weighted average maturity was around eight years. The maximum nominal amount, within non-current borrowings, maturing in any one calendar year was US$3.3 billion, which matures in 2018. At 31 December 2015, approximately half of Rio
Tintos total borrowings were at fixed interest rates.

Financial instruments and risk management

The Groups policies with regard to financial instruments and risk management are clearly defined and consistently applied. They are a fundamental part of
the Groups long-term strategy covering areas such as foreign exchange risk, interest rate risk, commodity price risk, credit risk, and liquidity risk and capital management. Further details of our Financial instruments and risk management are
disclosed in financial statements Note 30 Financial instruments and risk management of the Annual Report 2015.

The Annual Report 2015 shows
the full extent of the Groups financial commitments, including debt. The risk factors to which the Group is subject are summarised above in Item 3.D, Risk factors.

The effectiveness of internal controls continues to be a high priority in the Rio Tinto Group. The boards statement on internal control is set out in
the Risk management section.

Dividend

The 2015
interim dividend was 107.5 US cents (2014: 96.0 US cents) and the final dividend was determined as 107.5 US cents (2014: 119.0 US cents). Dividends paid on Rio Tinto plc and Rio Tinto Limited shares are equalised on a net cash basis; that is,
without taking into account any associated tax credits. Dividends are determined in US dollars. Rio Tinto plc dividends are paid and declared in pounds

Foreign exchange

The following sensitivities give the estimated effect on underlying earnings assuming that each exchange rate moved 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.

Off balance
sheet arrangements and contractual commitments

The table below presents information in relation to our material off balance sheet arrangements and
contractual commitments. Information regarding the Groups post retirement commitments and funding arrangements is provided in financial statements Note 45 Post-retirement benefits of the Annual Report 2015. Information regarding
the Groups close-down and restoration obligations is provided in financial statements Note 26 Provisions (including post-retirement benefits) of the Annual Report 2015. In addition financial statements Note 31 Commitments and
contingencies of the Annual Report 2015, provides further information regarding contingent liabilities, guarantees and commitments.

We expect that
these contractual commitments for expenditure, together with other expenditure and liquidity requirements, will be met from internal cash flow and, to the extent necessary, from the existing facilities.

10.E Taxation

US residents

The following is a summary of the principal
UK tax, Australian tax and US Federal 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 defined below. It is not
intended to be a comprehensive description of all the tax considerations that are relevant to all classes of taxpayer. Future changes in legislation may affect the tax consequences of the ownership of the Groups ADSs and shares.

It 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: a citizen or resident of the US; a domestic corporation; 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
shares or ADSs are held as capital assets for tax purposes. This section 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 liable for alternative minimum tax or net investment income tax, a person that actually 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 shares or ADSs 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.

##### Table of Contents

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 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. 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.

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

Taxation of dividends

US holders are not liable to
UK withholding tax on dividends paid by Rio Tinto plc. Under current UK tax legislation, dividends paid by Rio Tinto plc carry a tax credit equal to one-ninth of the net dividend, or ten per cent of the net dividend plus the tax credit. US holders
are not generally liable to UK tax on dividends by direct assessment (unless such US holder holds the shares or ADSs in connection with a branch, agency or permanent establishment in the UK) and the tax credit is not repayable to US holders.

Note that the UK dividend taxation rules are being reformed with effect from 6 April 2016. Assuming the legislation is enacted as drafted; UK
dividends will no longer carry a tax credit and will instead be subject to UK tax at special rates. However, there will be no change for US holders and no additional UK income tax liability will be due on dividends paid by Rio Tinto plc.

Capital gains

A US holder will not normally be
liable to UK tax on capital gains realised on the disposition of Rio Tinto plc ADSs or shares unless the holder carries on a trade, profession or vocation in the UK through a permanent establishment in the UK and the ADSs or shares have been used
for the purposes of the trade, profession or vocation or are acquired, held or used for the purposes of such a 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 be subject to UK
inheritance tax upon the holders death or on a transfer during the holders lifetime, unless the ADSs and shares form part of the business property of a permanent establishment in the UK or pertain to a fixed base situated in the UK used
in the performance of independent personal services. In the exceptional case where ADSs or shares are subject both to UK inheritance tax and to US Federal gift or estate tax, the UK Estate Tax Treaty generally provides for tax payments to be
relieved in accordance with the priority rules set out in the Treaty.

Stamp duty and stamp duty reserve tax

Transfers of Rio Tinto plc ADSs will not be subject to UK stamp duty provided that the transfer instrument is not executed in, and at all times remains
outside, the UK. Electronic paperless purchases of Rio Tinto plc shares are subject to stamp duty reserve tax (SDRT) at a rate of 0.5 per cent (rounded to the nearest penny). Purchases of Rio Tinto plc shares using a stock transfer form
are subject to Stamp Duty at a rate of 0.5 per cent 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
per cent (rounded to the nearest penny) 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.

##### Table of Contents

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) Rules discussed below, if you are a US holder, the gross amount of any dividend the Group 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.

Rio Tinto plc dividends paid to a non-corporate US holder
generally will be taxable at the reduced rate normally applicable to long-term capital gains provided certain requirements are met. Rio Tinto Limited dividends paid to a non-corporate US holder generally will be taxable at the reduced rate normally
applicable to long-term capital gains provided that Rio Tinto Limited qualifies for the benefits of the convention between the US and Australia, which Rio Tinto Limited believes it does, and certain other requirements are met. A US holder will 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.

You must include any Australian tax withheld from the dividend payment in this gross amount even though you do not in fact receive it. 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 dividend will not be eligible for the dividends-received deduction generally allowed to US corporations in respect
of dividends received from other US corporations. 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. 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 basis in the shares or ADSs and thereafter as capital gain.

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.

Taxation of capital gains

Subject to the PFIC Rules discussed below, if you are a US holder and you sell or otherwise dispose of the Groups ADSs or shares, you will recognise
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. 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.

##### Table of Contents

Passive Foreign Investment Company Rules

We believe that the Groups shares or ADSs should not be treated as stock of a PFIC for US federal income tax purposes, 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, unless the shares or ADSs are marketable stock and a US holder elects to be taxed annually on a mark-to-market basis with respect
to the shares or ADSs, gain realised on the sale or other disposition of the shares or ADSs would in general not be treated as capital gain. Instead, if you are a US holder, you would be treated as if you had realised such gain and certain
excess distributions rateably over your holding period for the shares or ADSs and would be taxed at the highest tax rate in effect for each such year to which the gain was allocated, together with an interest charge in respect of the tax
attributable to each such year. In addition, dividends that you receive from us will not be eligible for the reduced tax rates normally applicable to capital gains if we are a PFIC either in the taxable year of the distribution or the preceding
taxable year, but instead will be taxable at rates applicable to ordinary income.

Report of Independent Registered Public Accounting Firms

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

In our opinion, the accompanying Group balance sheet and the related Group income statement, the Group statement of comprehensive income, the Group cash flow
statement, the Group statement of changes in equity, present fairly, in all material respects, the financial position of the Rio Tinto Groupat 31 December 2015 and 2014, and the results of their operations and their cash flows for
each of the three years in the period ended 31 December 2015 in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board. Also, in our opinion, the Rio Tinto Group
maintained, in all material respects, effective internal control over financial reporting as of 31 December 2015, based on criteria established in Internal Control - Integrated Framework 2013 issued by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO). The Rio Tinto Groups management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the
effectiveness of internal control over financial reporting, included inManagements report on internal control over financial reporting. Our responsibility is to express opinions on these financial statements and on the Rio Tinto
Groups internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our
audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. 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.

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 authorizations of management and directors of the company; and (iii) provide reasonable assurance
regarding prevention or timely detection of unauthorized 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.
