Number 5/17
BHP BILLITON RESULTS FOR THE HALF YEAR ENDED 31 DECEMBER 2016
Despite improvements in our safety performance indicators, tragically there was a fatality at Escondida.
Attributable profit of US$3.2 billion, Underlying EBITDA(1) of US$9.9 billion and an Underlying EBITDA margin(2) of 54% for the December 2016 half year.
Productivity gains(3) of US$1.2 billion achieved for the period, including the benefit from the increase in estimated recoverable copper contained in the Escondida sulphide leach pad. We remain on track for US$1.8 billion of gains for the 2017 financial year, excluding any impact of industrial action at Escondida.
Unit cash costs(4) declined at our major assets compared to the December 2015 half year. Full year unit cost guidance has been adjusted to reflect unfavourable exchange rate movements.
Capital and exploration expenditure(5) decreased by 38% to US$2.7 billion. We now expect to invest US$5.6 billion in the 2017 financial year and US$6.3 billion in the 2018 financial year, reflecting an increase in exploration spend in both years following the successful bid for Trion in Mexico and positive drilling results at LeClerc and Caicos.
Strong operating performance and improving capital productivity supported free cash flow(2) of US$5.8 billion.
We strengthened our balance sheet, with net debt(2) of US$20.1 billion significantly reduced from US$26.1 billion at 30 June 2016 reflecting strong free cash flow generation and a favourable fair value adjustment of US$2.0 billion related to interest rate and exchange rate movements.
The Board has determined to pay an interim dividend of 40 US cents per share which is covered by free cash flow. This comprises the minimum payout of 30 US cents per share and an additional amount of 10 US cents per share.
Total copper production guidance for the 2017 financial year is under review as a result of ongoing industrial action at Escondida.
At Samarco, substantial progress is being made on the social and environmental remediation programs. A Preliminary Agreement has been entered into with the Federal Prosecutors’ Office. Restart of operations remains a focus but will only occur if it is safe, economically viable and has community support.

News Release
Results for the half year ended 31 December 2016
BHP Billiton Chief Executive Officer, Andrew Mackenzie, said: “This is a strong result that follows several years of a considered and deliberate approach to improve productivity and redesign our portfolio and operating model. Our steadfast commitment to this plan has positioned us to take full advantage in a period of higher prices with Underlying EBITDA up 65 per cent to US$9.9 billion.
The demerger of South32 and over US$7 billion of asset sales have shaped a portfolio that is now true to its strategy. Our assets are large, long-life and low-cost and provide exposure to a diverse mix of commodities with an attractive outlook. Our new operating model has sharpened the focus of our operations on the things that matter most: safety, volume and cost. A decline in unit costs at our major assets supported US$1.2 billion of productivity gains in the half, which follows the US$11 billion of annualised gains embedded over the last four years.
Greater productivity and increased capital efficiency supported strong free cash flow generation of US$5.8 billion. Strict adherence to our capital allocation framework has maximised the use of this cash. We have strengthened our balance sheet, with net debt falling sharply to close the period at US$20.1 billion. As we further strengthen the balance sheet our ability to invest counter-cyclically will only be enhanced. Our minimum 50 per cent dividend payout policy equates to 30 US cents per share. In recognition of the importance of shareholder returns and confidence in the Company’s performance, the Board has determined to pay an additional amount of 10 US cents per share, taking the overall interim dividend to 40 US cents per share.
We are confident in the long-term outlook for our commodities, particularly oil, with markets expected to rebalance in the near-term, and copper where we expect a deficit to emerge in the early 2020s. We have the right settings in place to substantially grow shareholder value.
The health and safety of our people and the communities in which we operate always come first
Health and safety are core to our values and we are committed to providing a safe workplace. BHP Billiton reported a record low Total Recordable Injury Frequency of 3.9 per million hours worked in the December 2016 half year. Despite the improvement in safety performance indicators, tragically one of our colleagues died at Escondida in October 2016.
We remain committed to supporting Samarco with the recovery of the communities and environment
Providing our support for the long-term recovery of the communities and environment affected by the Samarco tragedy on 5 November 2015 remains a priority for BHP Billiton. Substantial progress has been made on community resettlement, community health and environment restoration. The Renova Foundation has been operational since August 2016. Relocation of the communities most severely affected by the dam failure is progressing well. The program of works designed to contain tailings during the wet season was completed, as were improvements to water treatment plants along the Rio Doce.
On 18 January 2017, Samarco and its shareholders, Vale and BHP Billiton Brasil, entered into a Preliminary Agreement with the Federal Prosecutors in Brazil. This outlines the process and timeline for negotiation of a settlement of the R$155 billion (approximately US$47.5 billion) Civil Claim relating to the Fundão tailings dam failure. Under the timeframe established in the Preliminary Agreement, negotiations in relation to a final settlement arrangement with the Federal Prosecutors are expected to occur before the end of June 2017.
Restart of Samarco’s operations remains a focus but is subject to separate negotiations with relevant parties and will occur only if it is safe, economically viable and has the support of the community. Resuming operations requires government approvals, the granting of licenses by state authorities, the restructure of Samarco’s debt and the completion of commercial arrangements with Vale regarding the use of its Timbopeba pit.
In the December 2016 half year, BHP Billiton recorded an exceptional item of US$155 million (after tax) in relation to the Samarco dam failure. Additional commentary is included on page 35.

BHP Billiton Results for the half year ended 31 December 2016
Our diversified portfolio and simplified structure deliver strong financial performance
Earnings and margins
Attributable profit of US$3.2 billion includes an exceptional loss of US$40 million (after tax). That loss related to the Samarco dam failure (US$155 million), which was partially offset by US$115 million related to the cancellation of the Caroona exploration licence.
Underlying attributable profit of US$3.2 billion.
Underlying EBITDA of US$9.9 billion, with higher prices, operating cash cost improvements and other net movements (in total US$4.3 billion) more than offsetting the negative impact of currency and inflation movements (in total US$0.4 billion).
Underlying EBITDA margin of 54 per cent, compared with 40 per cent in the prior period.
Productivity and costs
US$1.2 billion of additional productivity gains compared to the December 2015 half year, with annualised productivity gains of more than US$11 billion already embedded over the last four years.
On track to deliver approximately US$1.8 billion of productivity gains during the 2017 financial year, excluding any impact of industrial action at Escondida.
Unit cash costs declined at our major assets when compared to the December 2015 half year.
Escondida, Conventional petroleum, Queensland Coal, and Western Australia Iron Ore (WAIO) unit cash costs(4) decreased by 37 per cent, 10 per cent, four per cent and one per cent, respectively, compared to the December 2015 half year. Lower Escondida unit cash costs reflected the benefit related to a change in estimated recoverable copper contained in the sulphide leach pad and favourable inventory movements. In local currency terms, Queensland Coal and WAIO unit costs declined by eight per cent and five per cent respectively.
Historical costs and updated guidance for the 2017 financial year (reflecting unfavourable exchange rate movements) are summarised below:
H1 FY17 H1 FY16 FY16 Current FY17(i) guidance Previous FY17(i) guidance FY17e vs FY16
Conventional petroleum unit cost(ii) (US$ per barrel of oil equivalent) 8.42 9.38 8.63 10 10 16%
Escondida unit cost (US$ per pound) 0.91 1.45 1.12 1.00(iii) 1.00 (11%)
Western Australia Iron Ore unit cost (US$ per tonne) 15.05 15.21 15.06 <15 14 (0%)
Queensland Coal unit cost (US$ per tonne) 56.43 58.69 55.25 54 52 (2%)
(i) Current 2017 financial year guidance is based on exchange rates of AUD/USD 0.75 and USD/CLP 663. Previous guidance was based on exchange rates of AUD/USD 0.71 and USD/CLP 698.
(ii) Excludes impact from revaluation of embedded derivatives in the Trinidad and Tobago gas contract: H1 FY17 US$46 million loss; H1 FY16 US$106 million gain; FY16 US$14 million gain.
(iii) Guidance unchanged pending the outcome of industrial action.
Cash flow and balance sheet
Delivered net operating cash flows of US$7.7 billion, reflecting higher commodity prices and further cash cost efficiencies.
Generated free cash flow of US$5.8 billion. Our Onshore US assets are now free cash flow positive, reflecting continued improvements in both operating and capital efficiency.
We continued to strengthen our balance sheet, finishing the period with net debt(2) of US$20.1 billion (30 June 2016: US$26.1 billion; 31 December 2015: US$25.9 billion). This reduction reflects strong free cash flow generation during the period as well as a non-cash fair value adjustment of US$2.0 billion related to interest rate and exchange rate movements, partially offset by the recognition of the Kelar finance lease of US$591 million.
Gearing ratio(2) of 24.3 per cent (30 June 2016: 30.3 per cent; 31 December 2015: 29.7 per cent).

News Release
Dividends
The dividend policy provides for a minimum 50 per cent payout of Underlying attributable profit at every reporting period. The minimum dividend payment for the period is 30 US cents per share.
Recognising the importance of cash returns to shareholders, the Board has determined to pay an additional amount of 10 US cents per share, taking the overall interim dividend to 40 US cents per share.
Projects and exploration
Capital and exploration expenditure of US$2.7 billion, down 38 per cent in the December 2016 half year, included maintenance spend of US$0.6 billion(6).
Following the successful bid for Trion in Mexico and positive drilling results at LeClerc and Caicos, a US$820 million exploration program is now planned for the current financial year.
All major projects under development are tracking to plan.
On 9 February 2017, BHP Billiton’s Board approved an investment of US$2.2 billion (BHP Billiton share) for the development of the Mad Dog Phase 2 project in the deepwater Green Canyon area of the Gulf of Mexico.
Capital and exploration expenditure is now expected to be US$5.6 billion for the 2017 financial year and US$6.3 billion in the 2018 financial year, reflecting an increase in exploration spend in both years.
Disciplined capital allocation is maximising shareholder value
Strict adherence to our capital allocation framework balances value creation, cash returns to shareholders and balance sheet strength in a transparent and consistent manner. This framework continues to provide valuable flexibility.
Our priorities for capital are to:
first, maintain safe and stable operations;
second, maintain a strong balance sheet through the cycle;
third, pay shareholders a minimum of 50 per cent of Underlying attributable profit as dividends; and
fourth, direct remaining cash to the value-maximising outcome, with debt reduction, investing in growth projects, buying back shares, paying additional dividend amounts and acquiring assets, all competing for capital.
With several of our commodity exposures currently trading above our long-term forecasts and with considerable economic and political uncertainty ahead, our bias for lowering debt remains. While the balance sheet is strong, our ongoing focus on debt reduction during this period of elevated commodity prices will protect the Company through periods of higher volatility and support counter cyclical investments as we move through the cycle. We will continue to invest in releasing near-term latent production capacity and progressing our broad suite of medium and long-term growth options which, while timed to meet identified market windows, are progressing well.
Outlook - near-term uncertainty, attractive long-term fundamentals
Economic outlook
World economic growth is likely to remain within the range of three to three and a half per cent in the 2017 calendar year. A move above this range will be delayed by rising political uncertainty which has the potential to weigh on international trade and business confidence.
Our view on China remains unchanged. China’s economic growth is expected to moderate in the coming year. The growth rate will remain consistent with official guidance. We anticipate a cooling of growth rates in the housing and automobile markets in combination with a continuation of strength in infrastructure. Manufacturing investment should stabilise, however exports may be challenged by the rising threat of protectionism.

BHP Billiton Results for the half year ended 31 December 2016
China’s policymakers will continue to seek a balance between the pursuit of reform and the maintenance of macroeconomic and financial stability. We expect a continuation of efforts to address excess capacity and improve balance sheet health in over-indebted sectors. Longer term, our view remains that China’s economic growth rate will decelerate as the working age population falls and the capital stock matures. China’s economic structure will continue to rebalance from industry to services and growth drivers will shift from investment and exports towards consumption. The outlook for the US economy is uncertain. The policy platform of the new administration points to a higher inflation environment than previously envisaged. The medium-term impact on growth is unclear, notwithstanding infrastructure related announcements, especially in the context of tighter financial conditions. In Europe and Japan, where the limits of monetary policy effectiveness may have been reached, any upside on growth will have to come from external demand sources. India’s economy should return to a healthy growth trajectory once the demonetisation shock recedes. The stabilisation of commodity prices should help put a floor under growth in resource-exporting emerging markets.
Commodities outlook
Crude oil prices trended higher in the first half of the 2017 financial year, particularly in the second quarter. OPEC reversed course on 30 November 2016 by agreeing to its first production cut since 2008 and the first cooperative deal with non-OPEC producers since 2001. These developments, and improving fundamentals, led to the price recovery. The market is expected to rebalance in the short-term, supporting prices as inventory levels normalise. However, political uncertainty, OPEC compliance rates and rising US output may offer some headwinds. The long-term outlook remains positive, underpinned by rising demand from the developing world and natural field decline. The domestic gas price in the US strengthened on a combination of winter heating demand, rising exports, and declining production. At the end of the reporting period, natural gas inventories were below the five-year average. This reduction in inventory levels is likely to offer price support in the near-term, notwithstanding the usual seasonal influences. The abundance of lower-cost supply is likely to moderate significant price inflation longer term, however, natural field decline and robust demand growth are forecast to incentivise development of incrementally higher-cost resources.
Copper prices improved towards the end of the first half of the 2017 financial year due to a combination of mine supply disruptions, stronger than expected Chinese demand and an improvement in investor sentiment. In the short- to medium-term, new and expanded production is expected to keep pace with demand and maintain a well-supplied market in balance. In the long-term, the copper outlook remains positive, as demand is supported by China’s shift towards consumption and the scope for substantial growth in emerging markets. A deficit is expected to emerge by the early 2020s as grade decline, water availability and limited high-quality development opportunities constrain the industry’s ability to cheaply meet growing demand.
Global steel production growth gained momentum in the first half of the 2017 financial year, led by a recovery in China. In the short-term, Chinese steel production growth is expected to moderate as the rate of growth in the housing market eases amidst escalating supply-side measures. Steel production in the rest of the world is likely to improve marginally, led by India. In the long-term, the global steel market will grow modestly, supported mainly by incremental demand from India and other populous emerging markets.
Iron ore prices have been highly volatile, starting the 2016 calendar year at low levels before recovering strongly in the Chinese spring. The price reached a two year high in December 2016, on the back of higher-than-expected steel production in China and tight supply of high grade ores. The market is likely to come under pressure in the short-term from moderating Chinese steel demand growth, high port inventories and incremental low cost supply. Metallurgical coal prices surged in the first half of the 2017 financial year, driven by pronounced shortages in both domestic Chinese and seaborne supply and reflected the impact of China’s 276-working day reform policy and adverse weather conditions in China and Queensland. Prices are expected to return to industry marginal cost once seaborne and Chinese supply constraints are eased. The application of China’s coal supply reform policy is a source of short-term uncertainty. We expect emerging markets such as India will provide long-term seaborne demand growth, while high-quality metallurgical coals will continue to offer steel makers value-in-use benefits.

US$M
Half year ended 31 December 2015 5,994
Net price impact:
Change in sales prices 3,852 Higher average realised prices for all our major commodities.
Price-linked costs (345) Increased royalties reflect higher realised prices.
3,507
Change in volumes:
Productivity 74 Productivity improvements across WAIO’s integrated supply chain offset by lower volumes at
Pampa Norte due to maintenance and lower copper grade as expected at Antamina.
Growth (199) Deferral of development activity in Onshore US and expected natural field decline.
(125)
Change in controllable cash costs(2):
Operating cash costs 1,142 Lower costs across the Group reflected a decrease in labour and contractor costs, favourable
impacts from a change in estimated recoverable copper in the Escondida sulphide leach pad
and inventory movements, partially offset by additional WAIO rail maintenance costs.
Exploration and business development (81) Higher petroleum exploration expense reflecting expensing of the Burrokeet wells.
1,061
Change in other costs:
Exchange rates (282) Impact of the stronger Australian dollar and Chilean peso against the US dollar.
Inflation (148) Impact of inflation on the Group’s cost base.
Fuel and energy 25 Lower diesel prices at minerals assets offset higher electricity costs at Olympic Dam.
Non-cash (189) Increased depletion of stripping capitalised in prior periods and lower strip ratio consistent with the Escondida mine plan.
One-off items 13 Reflects power outage at Olympic Dam, royalty and other matters.
(581)
Asset sales 163 Divestment of 50 per cent interest in Scarborough and non-core asset sales in Onshore US.
Ceased and sold operations (64) Divestment of San Juan and Navajo energy coal assets.
Other items (59) Higher average realised prices received by our equity accounted investments offset by the suspension of Samarco operations and unfavourable fair value movements in Trinidad and Tobago gas contract.

Other items includes Onshore US rig termination charges of US$6 million (2015: US$65 million) and impact from revaluation of embedded derivatives in Trinidad and Tobago gas contract of US$46 million loss (2015: US$106 million gain).
Total petroleum production for the December 2016 half year decreased by 15 per cent to 105.9 MMboe.
Conventional production was broadly unchanged at 66 MMboe as higher production at Bass Strait and North West Shelf offset natural field decline across the portfolio and the divestment of our gas business in Pakistan.
Onshore US production declined by 31 per cent to 40 MMboe as a result of the decision to defer development activity for value and natural field decline.
Total petroleum production guidance for the 2017 financial year remains unchanged at between 200 and 210 MMboe, comprising Conventional volumes between 123 and 127 MMboe and Onshore US volumes between 77 and
83 MMboe.
The increase in controllable cash costs reflects an increase in exploration expense, primarily attributable to expensing of the Burrokeet wells. Conventional unit costs declined by 10 per cent to US$8.42 per barrel during the December 2016 half year as a result of a decrease in workovers. Conventional unit cost guidance for the 2017 financial year is unchanged at approximately US$10 per barrel reflecting expected lower volumes as a result of seasonal demand in the second half of the year and timing of maintenance costs.
In the December 2016 half year, gains on asset divestments of US$196 million were recognised, with the majority related to the sale of 50 per cent of BHP Billiton’s interest in the undeveloped Scarborough area gas fields to Woodside Energy Limited as well as some non-core asset sales in Onshore US as we continue to optimise our acreage.
Petroleum capital expenditure declined by 42 per cent to US$845 million in the December 2016 half year. This included US$273 million of Onshore US drilling and development expenditure. Despite longer and more complex laterals and trials of new wells, our overall drilling and completion costs are now 25 per cent lower than the December 2015 half year, reflecting optimised well designs, operational efficiencies and procurement savings. Our Onshore US assets are now free cash flow positive reflecting these improvements in both operating and capital efficiency.

Petroleum capital expenditure guidance of approximately US$1.4 billion (excluding US$0.2 billion from capital creditor movements) for the 2017 financial year remains unchanged. This includes Conventional capital expenditure of US$0.8 billion which is focused on life extension projects at Bass Strait and North West Shelf. Onshore US capital expenditure is expected to be US$0.6 billion with development activity tailored to market conditions.

BHP Billiton Results for the half year ended 31 December 2016
On 9 February 2017, BHP Billiton’s Board approved the development of the Mad Dog Phase 2 project in the deepwater Green Canyon area of the Gulf of Mexico. The project includes a new floating production facility with the capacity to produce up to 140,000 gross barrels of crude oil per day from up to 14 production wells, and is expected to begin production in the 2022 financial year. The project cost has more than halved since 2013 with a revised field development concept leading to significant cost reductions and is now estimated to be US$9 billion on a 100 per cent basis (US$2.2 billion BHP Billiton share). This decision follows BP’s (the operator) sanction of the Mad Dog Phase 2 project in December 2016.
During the December 2016 half year, our Onshore US operated rig count was reduced from four to three. The current rig count includes the deployment of a rig in the Haynesville field in October 2016, following the successful execution of our hedging pilot. Additional hedge activity during the December 2016 quarter has led to approval of a second rig in the Haynesville with operations expected to commence in March 2017. We maintain the flexibility to add additional rigs in the Haynesville if market conditions are supportive. Completions activity in the Black Hawk was accelerated in the December 2016 quarter to drawdown drilled and uncompleted well inventory as market conditions improved. We have further optimised our acreage through trades and swaps in the Permian, and we continue to talk to neighbouring operators about mutually value accretive swaps to enable us to drill longer wells.
We are currently progressing trials in the Black Hawk, testing the potential for staggered wells to increase recovery, larger frac jobs to improve productivity and the potential of the Upper Eagle Ford horizon. We expect early results of these trials to be known during the September 2017 quarter. These trials, combined with our improved productivity, are significantly adding to our economic well inventory that can generate a minimum 15 per cent internal rate of return at US$50 per barrel and US$3 per MMbtu.

Petroleum exploration expenditure for the December 2016 half year was US$364 million, of which US$217 million was expensed. Activity for the period was largely focused in the deepwater Gulf of Mexico and the Caribbean. During the period, positive drilling results were announced at the Caicos well in the Gulf of Mexico, with oil encountered in multiple horizons, and at the LeClerc well in Trinidad and Tobago, with gas encountered in multiple horizons. The Wildling appraisal well has been accelerated to establish the resource scale and potential for commerciality of the oil discovered at Caicos. Studies have also commenced on the volume and potential market for the gas discovered at LeClerc to assess commerciality. Non-commercial hydrocarbons were encountered at the Burrokeet-2 well, concluding Phase 1 of the Trinidad and Tobago deepwater drilling campaign. The Invictus rig was mobilised to the Gulf of Mexico to drill the Wildling appraisal well, which spud on 8 January 2017.
During the December 2016 half year, BHP Billiton won the bid to acquire a 60 per cent participating interest in and operatorship of blocks AE-0092 and AE-0093, containing the Trion discovered resource, in Mexico. Subject to satisfaction of conditions, BHP Billiton anticipates signing the relevant agreements in the March 2017 quarter. Trion provides us with a first mover advantage and an opportunity to further appraise and potentially develop this area of the deepwater Gulf of Mexico.
Following the successful bid for Trion in Mexico and positive drilling results at the Caicos well in the Gulf of Mexico and the LeClerc well in Trinidad and Tobago, an US$820 million exploration program is now planned for the 2017 financial year, an increase of US$120 million from prior guidance.

(iv) Other includes: fuel and energy; asset sales; other items (including profit from equity accounted investments).
Total copper production for the December 2016 half year decreased by seven per cent to 712 kt due to reduced volumes at Olympic Dam, maintenance at Pampa Norte and lower copper grades, as planned, at Antamina. Total copper production guidance for the 2017 financial year is under review as a result of ongoing industrial action at Escondida.
The ramp-up of the Escondida Water Supply (EWS) and the Los Colorados Extension (LCE) projects late in the 2017 financial year will enable utilisation of three concentrators during the 2018 financial year. At Olympic Dam, development into the Southern Mining Area is progressing well and, following the major smelter maintenance campaign planned for the September 2017 quarter, is expected to support a gradual increase in copper production to 230 kt in the 2021 financial year.
The decrease in controllable cash costs included a US$275 million benefit related to the increase in estimated recoverable copper contained in the Escondida sulphide leach pad following commissioning of the Escondida Bioleach Pad Extension project and a US$120 million planned build of mined ore ahead of the commissioning of the LCE project. In addition, the December 2015 half year was negatively impacted by a drawdown of lower-grade stockpiled inventory and reduced recoveries from the ramp-up of Organic Growth Project 1.
As a result, unit cash costs at our operated copper assets decreased by 24 per cent to US$1.09 per pound during the December 2016 half year and included a 37 per cent reduction at Escondida, to US$0.91 per pound. In the 2017 financial year, unit costs at our operated copper assets are now expected to be US$1.15 per pound, higher than previous guidance of US$1.05 per pound, reflecting the impact of the power outage and unplanned refinery maintenance at Olympic Dam and a stronger Chilean peso and Australian dollar. Escondida unit cost guidance of approximately US$1.00 per pound remains unchanged for the 2017 financial year, pending the outcome of industrial action.

Total iron ore production for the December 2016 half year increased by four per cent to 118 Mt(7).
Western Australia Iron Ore (WAIO) production increased by four per cent to a record 136 Mt (100 per cent basis), as a result of the continued ramp-up of additional capacity at Jimblebar and improved rail track reliability.
Mining and processing operations at Samarco remain suspended following the dam failure.
Total iron ore production guidance for the 2017 financial year remains unchanged at between 228 and 237 Mt(7), or between 265 and 275 Mt(7) on a 100 per cent basis.
The new primary crusher and additional conveying capacity at Jimblebar were commissioned in December 2016 quarter. The ramp-up of additional capacity at the Jimblebar mining hub, completion of the rail renewal and maintenance program and further productivity improvements are expected to deliver an increase in system capacity to 290 Mtpa in the 2019 financial year.
WAIO unit cash costs declined by one per cent to US$15.05 per tonne, supported by continued reductions in labour and contractor costs and inventory stock build-up. This was partially offset by a stronger Australian dollar, a stock write-off at Yandi of US$0.29 per tonne and additional costs related to the rail renewal and maintenance programme of US$0.35 per tonne, which is ahead of schedule and now expected to be completed in the June 2017 quarter. Unit costs for the 2017 financial year are now expected to be less than US$15 per tonne as a result of unfavourable exchange rate movements.

Metallurgical coal production increased by one per cent to 21 Mt(7), and energy coal production decreased by four per cent to 14 Mt(7), in the December 2016 half year.
Strong metallurgical coal production at four Queensland Coal mines offset the cessation of production at Crinum. Excluding Crinum, production increased by eight per cent.
Energy coal production decreased at New South Wales Energy Coal (NSWEC), reflecting in-pit and run-of-mine inventory drawdowns in the prior period, and was partially offset by a stronger performance at Cerrejón.
Metallurgical coal and energy coal production guidance remains unchanged at 44 Mt(7) and 30 Mt(7) respectively for the 2017 financial year.
Queensland Coal unit cash costs declined by four per cent to US$56 per tonne, underpinned by a reduction in labour and contractor costs, favourable inventory movements and increased equipment and wash-plant utilisation. This was partially offset by a stronger Australian dollar over the half year. Unit costs for the 2017 financial year are now expected to be US$54 per tonne as a result of unfavourable exchange rate movements. NSWEC unit costs increased by nine per cent to US$46 per tonne due to lower volumes and a stronger Australian dollar which more than offset a reduction in labour costs and favourable inventory movements. Unit costs for the 2017 financial year are now expected to be US$40 per tonne, an increase from US$38 per tonne, as a result of unfavourable exchange rate movements.

BHP Billiton Results for the half year ended 31 December 2016
Group and unallocated items
Underlying EBITDA loss decreased by US$7 million to US$21 million in the December 2016 half year. The reduction reflected productivity improvements at Nickel West as a result of ongoing debottlenecking activities. This more than offset an unfavourable exchange rate impact on corporate provision balances.

News Release
The financial information on pages 27 to 48 has been prepared in accordance with IFRS. This news release including the financial information is unaudited. Variance analysis relates to the relative financial and/or production performance of BHP Billiton and/or its operations during the December 2016 half year compared with the December 2015 half year, unless otherwise noted.
The following abbreviations may have been used throughout this report: barrels (bbl); billion cubic feet (bcf); barrels of oil equivalent (boe); cost and freight (CFR); cost, insurance and freight (CIF), dry metric tonne unit (dmtu); free on board (FOB); grams per tonne (g/t); kilograms per tonne (kg/t); kilometre (km); metre (m); million barrels of oil equivalent (MMboe); million barrels of oil equivalent per day (MMboe/d); thousand cubic feet equivalent (Mcfe); million cubic feet per day (MMcf/d); million pounds (Mlb); million tonnes (Mt); million tonnes per annum (Mtpa); ounces (oz); pounds (lb); thousand barrels of oil equivalent (Mboe); thousand ounces (koz); thousand standard cubic feet (Mscf); thousand tonnes (kt); thousand tonnes per annum (ktpa); thousand tonnes per day (ktpd); tonnes (t); and wet metric tonnes (wmt).
The following footnotes apply to this Results Announcement:
(1) Underlying attributable profit, Underlying EBIT and Underlying EBITDA are used to reflect the underlying performance of BHP Billiton. We believe that these non-IFRS measures provide useful information, but should not be considered as an indication of, or as an alternative to, Attributable profit/(loss) as an indicator of actual operating performance or as an alternative to cash flow as a measure of liquidity. We believe focusing on Underlying EBITDA more closely reflects the operating cash generative capacity and hence the underlying performance of our business. Underlying EBITDA is the key measure that management uses internally to assess the performance of our segments and make decisions on the allocation of resources and is more relevant to capital intensive industries with long-life assets.
Underlying attributable profit is Attributable profit/(loss) excluding any exceptional items and non-controlling interest in exceptional items.
Underlying EBIT is earnings before net finance costs, taxation and any exceptional items. Underlying EBIT is reported net of net finance costs and taxation (expense)/benefit of US$156 million (2015: US$119 million) related to equity accounted investments and excludes exceptional items of US$61 million (2015: US$655 million) related to the share of loss from equity accounted investments.
Underlying EBITDA is Underlying EBIT before depreciation, amortisation and impairments of US$3,914 million for the half year ended 31 December 2016 (2015: US$4,652 million). Underlying EBITDA is reported before net finance costs and taxation (expense)/benefit, depreciation, amortisation and impairments related to equity accounted investments of US$267 million (2015: US$274 million) and excludes exceptional items of US$61 million (2015: US$655 million) related to share of loss from equity accounted investments.
(2) Further non-IFRS measures are defined as follows:
Adjusted effective tax rate – comprises Total taxation (expense)/benefit excluding exceptional items and exchange rate movements included in taxation (expense)/benefit divided by Profit/(loss) before taxation and exceptional items.
Net operating assets – represents operating assets net of operating liabilities including the carrying value of equity accounted investments and predominantly excludes cash balances, loan to associates, interest bearing liabilities and deferred tax balances. The carrying value of investments accounted for using the equity accounted method represents the balance of the Group’s investment in equity accounted investments, with no adjustment for any cash balances, interest bearing liabilities and deferred tax balances of the equity accounted investment.
Underlying basic earnings per share – represents underlying attributable profit per basic share.
Underlying EBITDA margin – comprises Underlying EBITDA excluding third party product EBITDA, divided by revenue excluding third party product revenue.
Controllable cash costs - comprises operating cash costs and exploration and business development costs. Management believes this measure provides useful information regarding the Group’s financial performance because it considers these expenses to be the principal operating and overhead expenses that are most directly under the Group’s control.
Underlying return on capital – represents annualised attributable profit after tax excluding exceptional items and net finance costs (after tax) divided by average capital employed. Capital employed is net assets before net debt.
We use a number of other financial measures (each of which is calculated with reference to IFRS measures) to assess our performance. Such other financial measures are defined as follows:
Free cash flow – comprises net operating cash flows less net investing cash flows.
Gearing ratio – represents the ratio of net debt to net debt plus net assets.
Net debt – comprises Interest bearing liabilities less Cash and cash equivalents for the total operations within the Group at the reporting date.
(3) Represents productivity-led volume efficiencies, operating cash cost efficiencies and exploration and business development savings. Productivity-led volume efficiencies refer to volume increases, excluding volume increases from major capital projects, multiplied by the prior period Underlying EBITDA margin. Operating cash cost efficiencies refer to the reduction in costs, excluding the impact of volume, price-linked costs, exchange rates, inflation, fuel and energy, non-cash costs, one-off items, asset sales, ceased and sold operations and other items. Exploration and business development savings refers to the reduction in total exploration and business development costs including capitalised exploration.
(4) Conventional petroleum unit cash costs exclude inventory movements, embedded derivatives movements, freight, third party and exploration expense; WAIO, Queensland Coal and NSWEC unit cash costs exclude freight and royalties; Escondida unit cash costs exclude freight and treatment and refining charges and are net of by-product credits. 2017 financial year unit cost guidance is based on exchange rates of AUD/USD 0.75 and USD/CLP 663. Other forward-looking guidance is based on internal exchange rate assumptions.
(5) Capital and exploration expenditure represents purchases of property, plant and equipment plus exploration expenditure from the Consolidated Cash Flow Statement.
(6) Maintenance capital includes non-discretionary spend for the following purposes: deferred development and production stripping; risk reduction, compliance and asset integrity.
(7) Iron ore production and guidance excludes production from Samarco; Energy Coal production and guidance excludes production from New Mexico Coal following divestments; Metallurgical coal production and guidance excludes production from Haju following the divestment of IndoMet Coal.

Financial Report
Notes to the Financial Information
1. Accounting policies
This general purpose financial report for the half year ended 31 December 2016 is unaudited and has been prepared in accordance with IAS 34 “Interim Financial Reporting” as issued by the International Accounting Standards Board (IASB), IAS 34 “Interim Financial Reporting” as adopted by the EU, AASB 134 “Interim Financial Reporting” as issued by the Australian Accounting Standards Board (AASB) and the Disclosure and Transparency Rules of the Financial Conduct Authority in the United Kingdom and the Australian Corporations Act 2001 as applicable to interim financial reporting.
The half year financial statements represent a “condensed set of financial statements” as referred to in the UK Disclosure and Transparency Rules issued by the Financial Conduct Authority. Accordingly, they do not include all of the information required for a full annual report and are to be read in conjunction with the most recent annual financial report. The comparative figures for the financial year ended 30 June 2016 are not the statutory accounts of the BHP Billiton Group for that financial year. Those accounts, which were prepared under IFRS, have been reported on by the Company’s auditor and delivered to the registrar of companies. The auditor has reported on those accounts; the report was unqualified, did not include a reference to any matters to which the auditors drew attention by way of emphasis without qualifying their report and did not contain statements under Section 498 (2) or (3) of the UK Companies Act 2006.
The half year financial statements have been prepared on the basis of the accounting policies and methods of computation consistent with those applied in the 30 June 2016 annual financial statements contained within the Annual Report of the BHP Billiton Group.
Rounding of amounts
Amounts in this financial report have, unless otherwise indicated, been rounded to the nearest million dollars.
Comparatives
Where applicable, comparative periods have been adjusted to disclose them on the same basis as the current period figures.

5. Earnings per share
Half year ended 31 Dec 2016 Half year ended 31 Dec 2015 Year ended 30 June 2016
Earnings/(loss) attributable to owners of BHP Billiton Group (US$M)

- Total 60.2 (106.5) (120.0)
Diluted earnings/(loss) per ordinary share (US cents)(c)
- Total 60.0 (106.5) (120.0)
(a) The calculation of the number of ordinary shares used in the computation of basic earnings per share is the aggregate of the weighted average number of ordinary shares of BHP Billiton Limited and BHP Billiton Plc outstanding during the period after deduction of the number of shares held by the Billiton Employee Share Ownership Plan Trust and the BHP Billiton Employee Equity Trust.
(b) For the purposes of calculating diluted earnings per share, the effect of 14 million dilutive securities has been taken into account for the half year ended 31 December 2016. The Group’s only potential dilutive instruments are share awards granted under employee share ownership plans.
The conversion of options and share rights would have decreased the loss per share for the half year ended 31 December 2015 and year ended
30 June 2016 and therefore its impact has been excluded from the diluted earnings per share calculated for those periods.
(c) Each American Depositary Share represents twice the earnings for BHP Billiton ordinary shares.
6. Dividends

Subsequent to the half year ended 31 December 2016, on 21 February 2017 BHP Billiton determined an interim dividend of 40.0 US cents per share (US$2,129 million), which will be paid on 28 March 2017.
At 31 December 2016, BHP Billiton Limited had 3,211 million ordinary shares on issue and held by the public and BHP Billiton Plc had 2,112 million ordinary shares on issue and held by the public. No shares in BHP Billiton Limited were held by BHP Billiton Plc at 31 December 2016 (30 June 2016: nil).
The Dual Listed Company merger terms require that ordinary shareholders of BHP Billiton Limited and BHP Billiton Plc are paid equal cash dividends on a per share basis. Each American Depositary Share (ADS) represents two ordinary shares of BHP Billiton Limited or BHP Billiton Plc. Dividends determined on each ADS represent twice the dividend determined on BHP Billiton ordinary shares.
BHP Billiton Limited dividends for all periods presented are, or will be, fully franked based on a tax rate of 30 per cent.

Financial Report
7. Financial risk management – Fair values
All financial assets and financial liabilities, other than derivatives, are initially recognised at the fair value of consideration paid or received, net of transaction costs as appropriate, and subsequently carried at fair value or amortised cost, as indicated in the tables below. Derivatives are initially recognised at fair value on the date the contract is entered into and are subsequently remeasured at their fair value.
The carrying amount of financial assets and liabilities measured at fair value is principally calculated based on inputs other than quoted prices that are observable for these financial assets or liabilities, either directly (i.e. as unquoted prices) or indirectly (i.e. derived from prices). Where no price information is available from a quoted market source, alternative market mechanisms or recent comparable transactions, fair value is estimated based on the Group’s views on relevant future prices, net of valuation allowances to accommodate liquidity, modelling and other risks implicit in such estimates.
The inputs used in fair value calculations are determined by the relevant segment or function. The functions support the assets and operate under a defined set of accountabilities authorised by the Executive Leadership Team. Movements in the fair value of financial assets and liabilities may be recognised through the income statement or in other comprehensive income.
For financial assets and liabilities carried at fair value, the Group uses the following to categorise the method used:
Fair value hierarchy
Valuation method
Level 1
Based on quoted prices (unadjusted) in active markets for identical financial assets and liabilities.
Level 2
Based on inputs other than quoted prices included within Level 1 that are observable for the financial asset or liability, either directly (i.e. as unquoted prices) or indirectly (i.e. derived from prices).
Level 3
Based on inputs not observable in the market using appropriate valuation models, including discounted cash flow modelling.
The financial assets and liabilities are presented by class in the tables below at their carrying values, which generally approximate to fair value. In the case of US$3,019 million (30 June 2016: US$3,020 million) of fixed rate debt not swapped to floating rate, the fair value at 31 December 2016 was US$3,421 million (30 June 2016: US$3,539 million). For financial instruments that are carried at fair value on a recurring basis, the Group determines whether transfers have occurred between levels in the hierarchy by reassessing categorisation (based on the lowest level input that is significant to the fair value measurement as a whole) at the end of each reporting period. There were no transfers between categories during the period.
For financial instruments not valued at fair value on a recurring basis, the Group uses a method that is categorised as Level 2.

Sensitivity of level 3 financial assets and liabilities
Financial instruments categorised as level 3 are shares and other investments available for sale and other derivative contracts with a carrying net amount of US$281 million (30 June 2016: US$261 million). Significant items are derivatives embedded in physical commodity purchase and sales contracts of gas in Trinidad and Tobago with a net assets fair value of US$174 million (30 June 2016: US$220 million).
The potential effect of using reasonably possible alternative assumptions in these models, based on a change in the most significant input, such as commodity prices, by an increase/(decrease) of 10 per cent while holding all other variables constant will increase/(decrease) profit after taxation by US$28 million (30 June 2016: US$34 million).

8. Significant events – Samarco dam failure
On 5 November 2015, the Samarco Mineração S.A. (Samarco) iron ore operation in Minas Gerais, Brazil experienced a tailings dam failure that resulted in a release of mine tailings, flooding the community of Bento Rodrigues and impacting other communities downstream (the Samarco dam failure).
Samarco is jointly owned by BHP Billiton Brasil Limitada (BHP Billiton Brasil) and Vale S.A. (Vale). BHP Billiton Brasil’s 50 per cent interest is accounted for as an equity accounted joint venture investment. BHP Billiton Brasil does not separately recognise its share of the underlying assets and liabilities of Samarco, but instead records the investment as one line on the balance sheet. Each period, BHP Billiton Brasil recognises its 50 per cent share of Samarco’s profit or loss and adjusts the carrying value of the investment in Samarco accordingly. Such adjustment continues until the investment carrying value is reduced to US$ nil, with any additional share of Samarco losses only recognised to the extent that BHP Billiton Brasil has an obligation to fund the losses, or when future investment funding is provided. After applying equity accounting, any remaining carrying value of the investment is tested for impairment.
Any charges incurred directly by BHP Billiton Brasil or other BHP Billiton entities are recognised 100 per cent in the Group’s results.
The financial impacts of the Samarco dam failure on the Group’s income statement, balance sheet and cash flow statement are shown in the table below and have been treated as an exceptional item. These do not include BHP Billiton Brasil’s share of the results of Samarco prior to the Samarco dam failure, which is disclosed in the note 3 Interests in associates and joint venture entities.

(c) At 31 December 2015, BHP Billiton Brasil Ltda adjusted its investment in Samarco to US$ nil (resulting from US$(655) million share of loss from Samarco and US$(525) million impairment) and at 30 June 2016 recognised a provision of US$(1,200) million for potential obligations under the Framework Agreement. US$(572) million of the US$(1,200) million provision represented an additional share of loss from Samarco with the remaining US$(628) million recognised as provision expense.
(d) Includes US$(61) million funding provided during the period and US$(150) million utilisation of the Samarco dam failure provision, of which US$(139) million allowed for the continuation of reparatory and compensatory programs in relation to the Framework Agreement and a further US$(11) million for dam stabilisation.
Equity accounted investment in Samarco
BHP Billiton Brasil’s investment in Samarco remains at US$ nil. BHP Billiton Brasil provided US$61 million funding under a working capital facility during the period and recognised additional share of losses of US$61 million. No dividends have been received by BHP Billiton from Samarco during the period. Samarco currently does not have profits available for distribution and is legally prevented from paying previously declared and unpaid dividends.

Dam failure provisions and contingencies
As at 31 December 2016, provisions and contingent liabilities for BHP Billiton Brasil are not materially different from those disclosed in note 3 ‘Significant events – Samarco dam failure’ in the 30 June 2016 Annual Report, subject to the updates set out below:
Environment and socio-economic rehabilitation
Preliminary Agreement
On 18 January 2017, Samarco, Vale and BHP Billiton Brasil entered into a Preliminary Agreement with the Federal Prosecutors’ Office in Brazil, which outlines the process and timeline for further negotiations towards a settlement regarding the R$20 billion (approximately US$6 billion) Public Civil Claim and R$155 billion (approximately US$47.5 billion) Federal Public Prosecution Office claim relating to the dam failure.
The Preliminary Agreement provides for the appointment of experts to advise the Federal Prosecutors in relation to social and environmental remediation and the assessment and monitoring of programs under the Framework Agreement. The expert advisors’ conclusions will be considered in the negotiation of a final settlement arrangement with the Federal Prosecutors. The parties will use best efforts to achieve a final settlement arrangement by 30 June 2017 under the timeframe established in the Preliminary Agreement.
Under the Preliminary Agreement, Samarco, Vale and BHP Billiton Brasil agreed interim security (Interim Security) comprising R$1.3 billion (approximately US$400 million) in insurance bonds, R$100 million (approximately US$30 million) in liquid assets, a charge of R$800 million (approximately US$245 million) over Samarco’s assets, and R$200 million (approximately US$60 million) to be allocated within the next four years through existing Framework Agreement programs in the Municipalities of Barra Longa, Rio Doce, Santa Cruz do Escalvado and Ponte Nova by 30 April 2017.
On 24 January 2017, Samarco, Vale and BHP Billiton Brasil provided the Interim Security to the Court which, subject to Court approval, will remain in place until the earlier of 30 June 2017 and the date that a final settlement arrangement is agreed between the Federal Prosecutors, and Samarco, Vale and BHP Billiton Brasil.
Framework Agreement
Mining and processing operations remain suspended following the dam failure. Samarco is currently progressing plans to resume operations, however, significant uncertainties surrounding the nature and timing of ongoing future operations remain. In light of these uncertainties and based on currently available information, at 31 December 2016, BHP Billiton Brasil has recognised a provision of US$1.1 billion before tax and after discounting (30 June 2016: US$1.2 billion), in respect of its potential obligations under the Framework Agreement.
The measurement of the provision requires the use of estimates and assumptions and may be affected by, among other factors, potential changes in scope of work required under the Framework Agreement including further technical analysis, costs incurred in respect of programs delivered, resolution of uncertainty in respect of operational restart, updates to discount and foreign exchange rates, resolution of existing and potential legal claims and the status of the Framework Agreement. As a result, future actual expenditures may differ from the amounts currently provided and changes to key assumptions and estimates could result in a material impact to the amount of the provision in future reporting periods.
As at 31 December 2016, BHP Billiton Brasil has paid US$139 million to allow for the continuation of reparatory and compensatory programs in relation to the Framework Agreement and a further US$11 million for dam stabilisation, with the total US$150 million offset against the provision for the Samarco dam failure.
On 25 November 2016, BHP Billiton Brasil approved a further US$181 million to support the Foundation, in the event Samarco does not meet its funding obligations under the Framework Agreement. Any support to the Foundation provided by BHP Billiton Brasil will be offset against the provision for the Samarco dam failure.

Legal
The following matters are disclosed as contingent liabilities:
Public Civil Claim
While a final decision by the Court on the issue of ratification of the Framework Agreement is pending, the Preliminary Agreement suspends a R$1.2 billion (approximately US$370 million) injunction order under the Public Civil Claim. The Preliminary Agreement also requests suspension of the Public Civil Claim with a decision from the Court pending.
The R$1.2 billion (approximately US$370 million) injunction order could be reinstated if the Preliminary Agreement is not approved by the Court or a final settlement arrangement is not agreed by 30 June 2017.
These proceedings do not affect compliance with the Framework Agreement.
Given the status of these proceedings, it is not possible at this time to provide a range of possible outcomes or a reliable estimate of potential future exposures for BHP Billiton Brasil.
Federal Public Prosecution Office claim
The Preliminary Agreement suspends the Federal Public Prosecution Office claim, including a R$7.7 billion (approximately US$2.4 billion) injunction request. However, proceedings may be resumed if the Preliminary Agreement is not approved by the Court. Given the status of these proceedings it is not possible at this time to provide a range of possible outcomes or a reliable estimate of potential future exposures for BHP Billiton Brasil.
Criminal Charges
The Federal Prosecutors’ Office has filed criminal charges against BHP Billiton Brasil, Samarco and Vale and certain employees and former employees of BHP Billiton Brasil (Affected Individuals) in the Federal Court of Ponte Nova, Minas Gerais. BHP Billiton Brasil rejects outright the charges against the company and the Affected Individuals and will defend the charges and fully support each of the Affected Individuals in their defence of the charges.
Under the criminal charges against Samarco, Vale and BHP Billiton Brasil and certain individuals, a R$20 billion (approximately US$6 billion) asset freezing order application was made by the Federal Prosecutors. The Preliminary Agreement requests suspension of the asset freezing order application with a decision from the Court pending.
Given the status of this matter it is not possible at this time to provide a range of possible outcomes or a reliable estimate of potential future exposures for BHP Billiton Brasil.
Other claims
Additional lawsuits and government investigations relating to the Samarco dam failure may be brought against BHP Billiton Brasil and possibly other BHP Billiton entities in Brazil or other jurisdictions.
BHP Billiton’s potential liabilities, if any, resulting from other pending and future claims, lawsuits and enforcement actions relating to the Samarco dam failure, together with the potential cost of implementing remedies sought in the various proceedings, cannot be reliably estimated at this time and therefore a provision has not been recognised and nor has any contingent liability been quantified for such matters.
Ultimately, all the legal matters disclosed as contingent liabilities could have a material adverse impact on BHP Billiton’s business, competitive position, cash flows, prospects, liquidity and shareholder returns.
BHP Billiton Insurance
BHP Billiton has third party liability insurance for claims related to the Samarco dam failure made directly against BHP Billiton Brasil or other BHP Billiton entities. Such claims may be externally insured up to US$360 million (when adjusted for BHP Billiton Brasil’s interest in Samarco). External insurers have been advised of the Samarco dam failure and a formal claim is being prepared. At 31 December 2016 an insurance receivable has not been recognised for any potential recoveries under insurance arrangements.

Commitments
Under the terms of the joint venture agreement, BHP Billiton Brasil does not have an existing obligation to fund Samarco. For the half year ended 31 December 2016, BHP Billiton Brasil has provided US$61 million funding to Samarco. On 25 November 2016, BHP Billiton Brasil made available a short-term facility of up to US$115 million to carry out remediation and stabilisation work and support Samarco’s operations. Funds will be released to Samarco only as required and subject to the achievement of key milestones.
Any additional requests for funding or future investment provided would be subject to a future decision, accounted for at that time.
The following section includes disclosure required by IFRS of Samarco Mineração S.A.’s provisions, contingencies and other matters arising from the dam failure.

Dam failure related provisions and contingencies
As at 31 December 2016, provisions and contingent liabilities for Samarco are not materially different from those disclosed in note 3 ‘Significant events – Samarco dam failure’ in the 30 June 2016 Annual Report, subject to the updates set out below:
Environmental and socio-economic remediation

BHP Billiton Results for the half year ended 31 December 2016
8. Significant events – Samarco dam failure (continued)
Framework Agreement
Samarco has recognised a provision of US$2.2 billion before tax and after discounting at 31 December 2016 (30 June 2016: US$2.4 billion), in respect of its obligations under the Framework Agreement based on currently available information.
The measurement of the provision requires the use of estimates and assumptions and may be affected by, amongst other factors, potential changes in scope of work required under the Framework Agreement including further technical analysis, costs incurred in respect of programs delivered, resolution of uncertainty in respect of operational restart, updates to discount and foreign exchange rates, resolution of existing and potential legal claims and the status of the Framework Agreement. As a result, future actual expenditures may differ from the amounts currently provided and changes to key assumptions and estimates could result in a material impact to the amount of the provision in future reporting periods.
Other
As at 31 December 2016, Samarco has recognised provisions of US$0.2 billion (30 June 2016: US$0.2 billion), in addition to its obligations under the Framework Agreement, based on currently available information. The magnitude, scope and timing of these additional costs are subject to a high degree of uncertainty and Samarco has indicated that it anticipates that it will incur future costs beyond those provided. These uncertainties are likely to continue for a significant period and changes to key assumptions could result in a material change to the amount of the provision in future reporting periods. Any such unrecognised obligations are therefore contingent liabilities and, at present, it is not practicable to estimate their magnitude or possible timing of payment. Accordingly, it is also not possible to provide a range of possible outcomes or a reliable estimate of total potential future exposures at this time.
Legal
Public Civil Claim
While a final decision by the Court on the issue of ratification of the Framework Agreement is pending, the Preliminary Agreement suspends a R$1.2 billion (approximately US$370 million) injunction order under the Public Civil Claim. The Preliminary Agreement also requests suspension of the Public Civil Claim with a decision from the Court pending. The R$1.2 billion (approximately US$370 million) injunction order could be reinstated if the Preliminary Agreement is not approved by the Court or a final settlement arrangement is not agreed by 30 June 2017.
These proceedings do not affect compliance with the Framework Agreement.
Given the status of these proceedings it is not possible at this time to provide a range of possible outcomes or a reliable estimate of potential future exposures for Samarco.
Federal Public Prosecution Office claim
The Preliminary Agreement suspends the Federal Public Prosecution Office claim, including a R$7.7 billion (approximately US$2.4 billion) injunction request. However, proceedings may be resumed if the Preliminary Agreement is not approved by the Court. Given the status of these proceedings it is not possible at this time to provide a range of possible outcomes or a reliable estimate of potential future exposures for Samarco.

Criminal Investigations
The Federal Prosecutors’ Office has filed criminal charges against Samarco, Vale and BHP Billiton Brasil and certain employees and former employees of Samarco (Affected Individuals) in the Federal Court of Ponte Nova, Minas Gerais. Samarco rejects outright the charges against the company and the Affected Individuals and will defend the charges. Under the criminal charges against Samarco, Vale and BHP Billiton Brasil and certain individuals, a R$20 billion (approximately US$6 billion) asset freezing order application was made by the Federal Prosecutors. The Preliminary Agreement requests suspension of the asset freezing order application with a decision from the Court pending.
Given the status of these proceedings it is not possible at this time to provide a range of possible outcomes or a reliable estimate of potential future exposures for Samarco.
Class Action Complaint – Bond holders
In November 2016, a putative class action complaint was filed in the U.S District Court for the Southern District of New York on behalf of all purchasers of Samarco’s ten year bond notes due 2022 - 2024 between 31 October 2012 and 30 November 2015 against Samarco and the former chief executive officer of Samarco. The complaint asserts claims under the U.S. federal securities laws and indicates that the plaintiff will seek certification to proceed as a class action.
The amount of damages sought by the plaintiffs on behalf of the putative class is unspecified. Given the preliminary status of this matter, it is not possible at this time to provide a range of possible outcomes or a reliable estimate of potential future exposures to Samarco.
Other claims
Other pending lawsuits and investigations are at the early stages of proceedings. Until further facts are developed; court rulings clarify the issues in dispute, liability and damages; trial activity nears, or other actions such as possible settlements occur, it is not possible to arrive at a range of outcomes or a reliable estimate of Samarco’s obligations arising from these matters and therefore Samarco has not recognised a provision or quantified a contingent liability.
Additional claims may be brought against Samarco. A provision has not been made by Samarco for claims yet to be filed. Given the significant uncertainties surrounding possible outcomes it is not possible for Samarco to arrive at a range of outcomes or a reliable estimate of the liability for any unfiled claims.
Samarco Insurance
Samarco has standalone insurance policies in place with Brazilian and global insurers. Samarco has notified insurers including those covering property, project and liability risks. Insurers loss adjusters and/or claims representatives continue to investigate and assist with the claims process. An insurance receivable has not been recognised by Samarco for any recoveries under insurance arrangements at 31 December 2016.
9. Subsequent events
On the 9th February 2017, production was suspended at Escondida as a result of ongoing industrial action. Given the uncertainty of when production will be recommenced, it is not possible to estimate the potential financial effect.
Other than the matters outlined elsewhere in this financial information, no matters or circumstances have arisen since the end of the half year that have significantly affected, or may significantly affect, the operations, results of operations or state of affairs of the Group in subsequent accounting periods.

– Our financial results may be negatively affected by exchange rate fluctuations
– Reduction in Chinese demand may negatively impact our results
– Actions by governments, additional regulation or political events in the countries in which we operate could have a negative impact on our business
– Failure to discover or acquire new resources, maintain reserves or develop new operations could negatively affect our future results and financial condition
– Potential changes to our portfolio of assets through acquisitions and divestments may have a material adverse effect on our future results and financial condition
– Increased costs and schedule delays may adversely affect our development projects
– If our liquidity and cash flow deteriorate significantly it could adversely affect our ability to fund our major capital programs
– We may not fully recover our investments in mining, oil and gas assets, which may require financial write-downs
– The commercial counterparties we transact with may not meet their obligations, which may negatively impact our results
– Unexpected natural and operational catastrophes may adversely impact our operations
– Cost pressures and reduced productivity could negatively impact our operating margins and expansion plans
– Our non-operated assets and our commercial counterparties may not comply with our standards
– Breaches in, or failures of, our information technology may adversely impact our business activities

BHP Billiton Results for the half year ended 31 December 2016
Independent Review Report
Independent Auditors’ review report of KPMG LLP (‘KPMG UK’) to the owners of BHP Billiton Plc and of KPMG (‘KPMG Australia’) to the owners of BHP Billiton Limited Introduction
For the purposes of these reports, the terms ‘we’ and ‘our’ denote KPMG UK in relation to its responsibilities under its terms of engagement to report to BHP Billiton Plc and KPMG Australia in relation to Australian professional and regulatory responsibilities and reporting obligations to the owners of BHP Billiton Limited.
The BHP Billiton Group (‘the Group’) consists of BHP Billiton Plc, BHP Billiton Limited and the entities they controlled during the half year ended 31 December 2016.
We have reviewed the accompanying condensed financial statements of the Group for the half year ended 31 December 2016 (‘half year financial statements’), which comprise the Consolidated Income Statement, Consolidated Statement of Comprehensive Income, Consolidated Balance Sheet, Consolidated Cash Flow Statement, Consolidated Statement of Changes in Equity, notes 1 to 9 comprising a summary of significant accounting policies and other explanatory information. KPMG Australia considers the Directors’ declaration to be part of the half year financial statements when forming its conclusion.
Directors’ Responsibilities
The Directors are responsible for preparing the half year financial report which give a true and fair view in accordance with:
● The Disclosure and Transparency Rules (‘the DTR’) of the United Kingdom’s Financial Conduct Authority (‘the UK
FCA’), and under those rules, in accordance with IAS 34 Interim Financial Reporting as adopted by the European Union (‘EU’); and
● Australian Accounting Standards and the Australian Corporations Act 2001 and for such internal control as the Directors determine is necessary to enable the preparation of the half year financial statements that are free from material misstatement, whether due to fraud or error; selecting and applying appropriate accounting policies; and making accounting estimates that are reasonable in the circumstances.
Respective Responsibilities of KPMG UK and KPMG Australia
KPMG UK’s report is made solely to BHP Billiton Plc in accordance with the terms of KPMG UK’s engagement to assist BHP Billiton Plc in meeting the requirements of the DTR of the UK FCA. KPMG UK’s review has been undertaken so that it might state to BHP Billiton Plc those matters it is required to state to it in this report and for no other purpose. To the fullest extent permitted by law, KPMG UK does not accept or assume responsibility to anyone other than BHP Billiton Plc, for KPMG UK’s review work, for this report, or for the conclusions it has reached.
KPMG Australia has performed an independent review of the half year financial statements and Directors’ declaration in order to state whether, on the basis of the procedures described, it has become aware of any matter that makes KPMG Australia believe that the half year financial statements and Directors’ declaration are not in accordance with the Australian Corporations Act 2001 including: giving a true and fair view of the Group’s financial position as at 31 December 2016 and its performance for the half year ended on that date; and complying with Australian Accounting Standard AASB 134 Interim Financial Reporting and the Australian Corporations Regulations 2001.
Our responsibility is to express a conclusion on the half year financial report based on our review.
Scope of Review
KPMG UK conducted its review in accordance with International Standard on Review Engagements (UK and Ireland)
2410 Review of Interim Financial Information Performed by the Independent Auditor of the Entity (‘ISRE 2410’) issued by the Auditing Practices Board for use in the UK.

Financial Report
KPMG Australia conducted its review in accordance with Auditing Standard on Review Engagements ASRE 2410 Review of a Financial Report Performed by the Independent Auditor of the Entity (‘ASRE 2410’), as issued by the Australian Auditing and Assurance Standards Board. As auditor of BHP Billiton Limited, ASRE 2410 requires that KPMG Australia complies with the ethical requirements relevant to the audit of the annual financial statements.
A review of half year financial statements consists of making enquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with auditing standards and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.
Independence
In conducting its review, KPMG Australia has complied with the independence requirements of the Australian Corporations Act 2001. Review conclusion by KPMG UK
Based on our review, nothing has come to our attention that causes us to believe that the condensed half year financial statements for the six months ended 31 December 2016 are not prepared, in all material respects, in accordance with IAS 34 Interim Financial Reporting, as adopted by the EU, and the DTR of the UK FCA.
