BHP RESULTS

FOR THE HALF YEARED 31 DECEMBER 2017

Safety: We are committed to making our workplaces safer, as we achieve nothing unless we achieve it safely

-- Tragically, we had two fatalities during the period, one at our Permian operations and one at Goonyella Riverside.

Maximise cash flow: Strong free cash generation underpinned by higher prices

-- Attributable profit of US$2.0 billion (includes an exceptional loss of US$2.0 billion predominantly related to the US tax reform) and Underlying attributable profit of US$4.1 billion.

-- Underlying EBITDA(ii) of US$11.2 billion and Underlying EBITDA margin(iii) of 53% reflect higher commodity prices and a solid operating performance.

   --      Net operating cash flow of US$7.3 billion and free cash flow(i) of US$4.9 billion. 

-- A negative productivity movement of US$496 million was largely due to anticipated factors. We remain on track to deliver productivity gains of US$2 billion over the two years to the end of the 2019 financial year, weighted to the second year.

Capital discipline: Delivering debt reduction and value accretive investments

-- Net debt(i) down by US$0.9 billion from 30 June 2017 to US$15.4 billion reflecting strong free cash flow generation.

-- Capital and exploration expenditure(v) increased by 6% to US$2.9 billion. Guidance unchanged at US$6.9 billion for the 2018 financial year and expected to remain below US$8 billion per annum for the 2019 and 2020 financial years.

Value and returns: Detailed asset-level plans to increase shareholder value and returns

-- The Board has determined to pay an interim dividend of 55 US cents per share which includes an additional amount of 17 US cents per share above the 50% minimum payout policy (equivalent to US$0.9 billion).

-- Underlying return on capital employed(iii) of 12.8% (after tax) with further improvement expected.

-- Onshore US exit for value progressing to plan, with initial bids expected to be received in the June 2018 quarter.

BHP Chief Executive Officer, Andrew Mackenzie:

"Higher commodity prices and a solid operating performance delivered free cash flow of US$4.9 billion. We used this cash to further reduce net debt and increase returns to shareholders through higher dividends. We are on track to deliver further productivity gains of US$2 billion by the end of the 2019 financial year as we secure improvements in both operating and capital productivity, aided by smarter technology application across our value chain. Our capital expenditure program remains focused on high-return, low-risk development opportunities in commodities where we see greatest potential. We remain firm in our resolve to maximise cash flow, maintain discipline and increase shareholder value and returns."

Results for the half year ended 31 December 2017

Safety is our highest priority

The health and safety of our employees and contractors, and that of the broader communities in which we operate, are central to the success of our organisation. Tragically, two of our colleagues died during the period, one at our Permian Basin operations in November 2017 and one at Goonyella Riverside in August 2017. Our Total Recordable Injury Frequency (TRIF) was 4.1 per million hours worked in the December 2017 half year, a two per cent decrease from 30 June 2017. We are committed to becoming safer through how we design our facilities and how we plan and execute our work, with an increasing application of technology to remove people from harms' way.

Making significant progress on the social and environmental remediation programs in Brazil

BHP remains committed to supporting the Renova Foundation with the recovery of communities and ecosystems affected by the Samarco tragedy.

The Renova Foundation's compensation program is making good progress. Over 260,000 claims for temporary interruption to water supplies immediately following the dam failure have been resolved. The focus of the program is now shifting to compensating for other damages including loss of property, equipment and loss of income. The resettlement of the most impacted communities is progressing, however, at a pace slower than planned due to regulatory and licensing challenges. The river remediation programs continue to stabilise the tailings material, resulting in improvements to water quality and aquatic ecology.

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 the granting of licences by state and federal authorities, community hearings and an appropriate restructure of Samarco's debt.

In the December 2017 half year, BHP reported an exceptional loss of US$210 million (after tax) in relation to the Samarco dam failure. This includes funding of US$50 million, direct costs of US$29 million, discount unwinding of US$44 million and other movements in the provision, including foreign exchange, of US$87 million. Additional commentary is included on page 42.

Financial performance

Earnings and margins

-- Attributable profit of US$2.0 billion includes an exceptional loss of US$2.0 billion (after tax), compared to an attributable profit of US$3.2 billion, including an exceptional loss of US$40 million (after tax), in the prior period. The December 2017 half year exceptional loss is related to the US tax reform and Samarco dam failure. The December 2016 half year exceptional loss was related to the Samarco dam failure, partially offset by the reimbursement received on cancellation of the Caroona exploration licence.

-- Underlying attributable profit of US$4.1 billion, compared to US$3.2 billion in the prior period.

-- Profit from operations of US$6.7 billion, compared to US$6.1 billion in the prior period, has increased as a result of higher prices and volumes, partially offset by higher costs.

-- Underlying EBITDA of US$11.2 billion, with higher prices and volume productivity (in total US$2.6 billion) more than offsetting the impacts of higher costs, unfavourable exchange rate movements, inflation and other net movements (in total US$1.3 billion).

   --      Underlying EBITDA margin of 53 per cent, compared with 54 per cent in the prior period.

Productivity and costs

-- A negative movement in productivity of US$496 million was recorded reflecting: lower volumes and unfavourable fixed cost dilution at Olympic Dam as a result of the smelter maintenance campaign (US$202 million); the impact of reduced volumes at Queensland Coal and Petroleum (US$225 million); and a favourable change in estimated recoverable copper in the Escondida sulphide leach pad in the prior period (US$206 million); partially offset by an increase in Escondida copper volumes and lower labour and contractor costs at Western Australia Iron Ore (WAIO).

-- Productivity guidance remains unchanged, with US$2 billion of gains expected to be delivered over the two years to the end of the 2019 financial year, weighted to the second year.

-- Full year unit cost guidance(vi) remains unchanged for Petroleum, Copper, Iron Ore and Energy Coal (based on an exchange rate of AUD/USD 0.75 and USD/CLP 663).

-- Queensland Coal unit costs for the 2018 financial year are now expected to be US$66 per tonne (based on an exchange rate of AUD/USD 0.75), an increase from previous guidance of US$59 per tonne, as a result of reduced low-cost Broadmeadow and Blackwater volumes, production from higher cost pits and rising inflationary pressures. Unit costs for the second half of the 2018 financial year are expected to be US$63 per tonne with challenging roof conditions at Broadmeadow expected to continue through the March 2018 quarter.

(1) Other copper comprises Pampa Norte, Olympic Dam and Antamina.

-- We expect Group copper equivalent volume growth(vii) of six per cent for the 2018 financial year, down from previous guidance of seven per cent, due to lower volumes now expected at Broadmeadow and Blackwater.

Cash flow and balance sheet

-- Net operating cash flows of US$7.3 billion reflect higher commodity prices, a solid operating performance and a final corporate income tax payment in Australia of US$1.3 billion related to the prior year.

   --    Free cash flow of US$4.9 billion. Our Onshore US assets remain free cash flow positive(iii) . 

-- We continued to strengthen our balance sheet with a reduction in net debt of US$0.9 billion, to finish the period at US$15.4 billion (30 June 2017: US$16.3 billion; 31 December 2016: US$20.1 billion). This reduction reflects strong free cash generation during the period, offset by an increase in dividends to shareholders, record dividends paid to non-controlling interests of US$0.9 billion and a non-cash fair value adjustment of US$0.7 billion related to interest rate and exchange rate movements(viii) .

-- Gearing ratio(i) of 19.9 per cent (30 June 2017: 20.6 per cent; 31 December 2016: 24.3 per cent).

-- We are on track to reach our net debt range of US$10 to US$15 billion before year-end and will maintain a strong balance sheet through the commodity price cycle. We are targeting the lower half of the net debt range while commodity prices remain elevated.

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 38 US cents per share.

-- Recognising the importance of cash returns to shareholders, the Board has determined to pay an additional amount of 17 US cents per share or US$0.9 billion, taking the interim dividend to 55 US cents per share or US$2.9 billion. This is equivalent to a 72 per cent payout ratio.

Capital and exploration

-- Capital and exploration expenditure of US$2.9 billion, up six per cent in the December 2017 half year, included maintenance spend(ix) of US$1.0 billion and exploration of US$0.5 billion.

-- Capital and exploration expenditure guidance is unchanged at US$6.9 billion for the 2018 financial year, as a decrease in Onshore US capital expenditure of US$100 million is offset by unfavourable exchange rate movements.

-- A US$0.9 billion exploration program is planned for the 2018 financial year and includes petroleum exploration expenditure of US$715 million.

-- We expect capital and exploration expenditure to remain below US$8 billion per annum in the 2019 and 2020 financial years, subject to exchange rate movements.

Capital allocation framework

Adherence to our capital allocation framework aims to balance value creation, cash returns to shareholders and balance sheet strength in a transparent and consistent manner, and is embedded in every capital decision we make. Our balance sheet is strong and remains a fundamental enabler of our strategy. This will protect the Group through periods of heightened volatility and support counter cyclical investments as we move through the cycle.

Outlook

Economic outlook

World economic growth was in the range of three and a half to three and three quarters per cent in the 2017 calendar year. A similar outcome is expected in the 2018 calendar year.

China's economic growth is expected to slow modestly in the 2018 calendar year, close to the lower end of the official GDP target range of six and a half to seven per cent, as continued strength in infrastructure and resilience in external trade is offset by a cooling of growth rates in the housing and automobile markets.

The US economy should see a near-term boost to growth with the passing of the US Tax Cuts and Jobs Act (the TCJA). In Europe and Japan, where the limits of monetary policy effectiveness may have been reached, any upside on growth in the medium term will have to come from external demand sources. India's economy is on a healthy growth trajectory, supported by positive reform signposts.

Commodities outlook

Crude oil prices trended higher during the December 2017 half year. Production discipline by OPEC members and non-OPEC participants (the 'Vienna Group') and strong demand growth contributed to a substantial reduction in the inventory overhang. The tighter market, rising geopolitical tensions, unplanned supply outages, plateauing of the US rig count and extension of Vienna Group production cuts aided market sentiment. A roughly balanced market is forecast for the 2018 calendar year.

The US domestic gas price was relatively stable as growth in exports, strong power demand over summer and delays to North East pipeline projects helped eliminate the storage surplus relative to the five-year average. We anticipate that the market will return to surplus in the 2018 calendar year, as record US production is facilitated by the start-up of major North East pipelines.

Copper prices rose over the December 2017 half year. Solid global consumption was underpinned by continued strength in China, in particular from consumer durables. On the supply side, the announcement that China would ban lower-grade copper scrap imports and the potential for supply disruptions due to the large number of upcoming labour negotiations in South America drove sentiment. Over the next few years, the global copper market is expected to remain finely balanced and vulnerable to supply shocks, particularly in the concentrate segment.

The global steel industry continued its recovery in the December 2017 half year, with production growth led by emerging markets. China's steel supply-side reforms have resulted in a structural improvement in industry profitability. China's steel production growth is expected to moderate in the 2018 calendar year due to a cooling in the housing and automobile sectors. However, the recovery in the rest of the world is likely to continue, with solid demand conditions and lower Chinese steel exports.

Iron ore prices improved over the December 2017 half year. Demand for high-grade products remained firm on the back of high steel margins, which benefitted from Chinese steel supply-side reforms and winter production restrictions. This has resulted in an elevated price differential between high and low-grade ore price indexes. In the medium to longer term, ongoing Chinese supply-side reforms, the shift of steel capacity to coastal regions and more stringent environmental policies are expected to underpin demand for high-quality seaborne iron ore.

Metallurgical coal prices strengthened in the December 2017 half year. Chinese demand for higher quality metallurgical coal remained firm throughout the period despite the onset of winter emission restrictions. Additionally, domestic supply was constrained due to safety and environmental concerns. High prices have incentivised additional seaborne supply from the US and Mozambique. In the medium term, China's coal supply-side reforms and environmental considerations will support demand for higher quality metallurgical coal.

(1) Exceptional items of US$(166) million excludes net finance costs of US$(44) million included in the total US$(210) million related to the Samarco dam failure.

Profit from operations has increased as a result of favourable realised price movements across all major commodities and higher volumes, partially offset by higher costs, impairment charges predominantly related to conveyors at Escondida and higher depreciation charges following the commissioning of the Escondida Water Supply project.

Depreciation, amortisation and impairments

Depreciation, amortisation and impairments increased by US$422 million to US$4.3 billion, reflecting impairment charges predominantly related to conveyors at Escondida and higher depreciation following the commissioning of the Escondida Water Supply project in June 2017.

Net finance costs

Net finance costs increased by US$93 million to US$670 million due to costs related to the September 2017 bond repurchase program and higher benchmark interest rates in the period. This was partially offset by a lower average debt balance following the repayment on maturity of Group debt and the bond repurchase program.

The Group's adjusted effective tax rate(iii) , which excludes the influence of exchange rate movements and exceptional items, was 28.1 per cent (31 December 2016: 34.7 per cent). The adjusted effective tax rate reflects the impact of higher profits from equity accounted investments and depletion allowances claimed in the United States. As a result, the adjusted effective tax rate is now expected to be in the range of 30 to 35 per cent for the 2018 financial year.

Other royalty and excise arrangements which are not profit based are recognised as operating costs within Profit before taxation. These amounted to US$986 million during the period (31 December 2016: US$963 million).

On 22 December 2017, the US President signed the TCJA into law. The TCJA (effective 1 January 2018) includes a broad range of tax reforms affecting the Group, including, but not limited to, a reduction of the US corporate tax rate from 35 per cent to 21 per cent and changes to international tax provisions. As a result of the TCJA, the Group has recognised an exceptional income tax charge of US$1,828 million (refer exceptional items footnote (2) below for further details). Longer term, we expect US attributable profits to be positively impacted by the lower US corporate tax rate.

Exceptional items

The following table sets out the exceptional items for the December 2017 half year. Additional commentary is included on page 34.

BHP Billiton Plc shareholders registered on the South African section of the register will not be able to dematerialise or rematerialise their shareholdings between the dates of 7 March and 9 March 2018 (inclusive), nor will transfers between the UK register and the South African register be permitted between the dates of 2 March and 9 March 2018 (inclusive). American Depositary Shares (ADSs) each represent two fully paid ordinary shares and receive dividends accordingly. Details of the currency exchange rates applicable for the dividend will be announced to the relevant stock exchanges following conversion and will appear on the Group's website.

Our Board has approved the establishment of a Dividend Reinvestment Plan (involving on-market purchase) for implementation for the final dividend in the 2018 financial year. Subject to the terms and conditions of the Plan, shareholders will be able to elect to use their cash dividend for the purchase of BHP shares.

Debt management and liquidity

During the December 2017 half year, the Group continued to focus on debt reduction, with no new debt issued and an A$1.0 billion Australian bond repaid at maturity. In addition, a bond repurchase program of US$2.9 billion was completed on 22 September 2017. The total cost in relation to the repurchase program was US$71 million, which has been reported in net finance costs. The program was funded by BHP's strong cash position and targeted short-dated US dollar, Euro and GBP bonds. The early repayment of the bonds has extended BHP's average debt maturity profile. The repayment of maturing debt and the bond repurchase program, partially offset by fair value adjustments, contributed to a US$2.8 billion overall decrease in the Group's gross debt, from US$30.5 billion at 30 June 2017 to US$27.7 billion at 31 December 2017.

At the subsidiary level, Escondida issued US$0.5 billion of new long-term debt to fund capital expenditure and for general corporate purposes.

The Group has a US$6.0 billion commercial paper program backed by a US$6.0 billion revolving credit facility which expires in May 2021. As at 31 December 2017, the Group had no outstanding US commercial paper, no drawn amount under the revolving credit facility and US$12.3 billion in cash and cash equivalents.

Corporate governance

On 23 August 2017, we announced the appointment of Terry Bowen and John Mogford to the BHP Board as independent Non-executive Directors, effective 1 October 2017. We also announced that Grant King decided to not stand for election at the 2017 Annual General Meeting and he would be retiring from the Board on 31 August 2017, and that Malcolm Brinded decided to not stand for re-election at the 2017 Annual General Meeting with 18 October 2017 being his final day on the Board.

The Board and management regularly review the Dual Listed Company (DLC) structure and our portfolio of assets so as to optimise long-term value for all shareholders. We have considered unification of the DLC structure a number of times over the past years, and will keep it under review. We would change the DLC structure if it were in the best interests of all shareholders. Our view on unification of the DLC structure is based on cost and benefit analysis. Currently, we consider that the costs and risks of collapsing the DLC outweigh the potential benefits.

Total petroleum production for the December 2017 half year decreased by seven per cent to 99 MMboe due to the impact of Hurricane Harvey and Hurricane Nate on US petroleum assets and natural field decline. Conventional production declined by three per cent to 64 MMboe and Onshore US production declined by 13 per cent to 35 MMboe.

Controllable cash costs increased by US$67 million and includes:

   --    US$91 million - unfavourable fixed cost dilution from declining volumes; 
   --    US$61 million - planned maintenance activity at Atlantis, Macedon and Pyrenees; and 

-- US$(81) million - lower exploration expenses due to the Burrokeet wells write-off in the December 2016 half year.

15

Profit on sale of assets decreased by US$187 million reflecting the divestment of a small portion of the Hawkville acreage, completed in the September 2017 quarter, more than offset by the sale of 50 per cent of BHP's interest in the undeveloped Scarborough area gas fields in the prior period.

Conventional unit costs increased by 23 per cent to US$10.38 per barrel of oil equivalent during the December 2017 half year, due to the impact of lower volumes and unfavourable foreign exchange movements. Unit cost guidance for the 2018 financial year remains unchanged at approximately US$10 per barrel (based on an exchange rate of AUD/USD 0.75).

Onshore US development activity

Onshore US drilling and development expenditure for the December 2017 half year was US$336 million (U$511 million on an activity basis), 23 per cent higher than the same period last year reflecting an increase from three to nine rigs.

We continue to drill longer laterals and complete larger frac jobs. By changing the well design, we enhanced staggered laterals and demonstrated commerciality of Upper and Lower Eagle Ford co-development and confirmed first year production improvements associated with larger completions in the Permian. These longer and more complex laterals are reflected in an overall increase of our Onshore US drilling and completion costs per well, but are more than offset by the additional well productivity. During the December 2017 half year, our Onshore US assets were free cash flow positive(iii) .

We expect to lower our rig count during the second half of the 2018 financial year as rig contracts expire and we adjust our capital plans to optimise value for our planned exit. Onshore US production volumes for the 2019 financial year are expected to remain broadly unchanged from previous guidance, as enhanced well performance offsets lower rig activity.

We continue to progress a number of alternatives to exit our Onshore US assets for value. We have commenced marketing each of the fields and the data room for the Fayetteville field has been opened. We continue preparing all appropriate documentation ahead of data rooms for the remaining fields being opened in March 2018. We expect to receive trade sale bids during the June 2018 quarter, evaluate and negotiate those bids in the September 2018 quarter and potentially announce completed transactions in the first half of the 2019 financial year. In parallel, we continue to explore potential asset swap opportunities and exit via demerger or Initial Public Offering.

Petroleum exploration

Petroleum exploration expenditure for the December 2017 half year was US$378 million, of which US$137 million was expensed. Activity for the period was largely focused in the deepwater Gulf of Mexico.

In the Gulf of Mexico, no commercial hydrocarbons were encountered at Scimitar. The well was plugged and abandoned in February 2018, with the associated exploration costs to be expensed in the second half of the 2018 financial year. The Wildling-2 well and side track were successfully completed in the September 2017 quarter and found oil in multiple horizons. Evaluation is ongoing to assess the scale of the discovery and we are preparing our appraisal plans for Wildling with the expectation to continue drilling in the 2019 financial year.

In Mexico, the Exploration and Appraisal plan has been endorsed by Pemex and approval from Mexico's National Hydrocarbon Commission was granted in February 2018. Planning continues for exploration and appraisal wells on Trion which are expected to be drilled in the 2019 financial year.

In Trinidad and Tobago, we continue appraisal work in the Southern Gas region (known as Magellan) to assess the potential commercialisation of the gas discovery at LeClerc and follow-on potential at the Victoria and Concepcion prospects. Preparations continue for Phase 2 deepwater exploration which is expected to commence in the June 2018 quarter.

In Australia, the seismic survey in the Exmouth sub-basin is progressing to plan with processed data to be delivered during the June 2018 quarter.

(1) Average realised price: copper US$3.20/lb (2016: US$2.41/lb).

(2) Non-cash includes: development stripping capitalisation and depletion.

(3) One-off items reflects the state-wide power outage and resultant shutdown at Olympic Dam in the December 2016 half year.

(4) Other includes: fuel and energy; other items (including profit from equity accounted investments).

Total copper production for the December 2017 half year increased by 17 per cent to 833 kt due to increased volumes at Escondida (ramp-up of the Los Colorados Extension project), which more than offset reduced volumes at Olympic Dam (planned smelter maintenance campaign recently completed). Operations at Olympic Dam continue to ramp-up to full-capacity during the March 2018 quarter, with production guidance unchanged at 150 kt for the 2018 financial year.

Controllable cash costs increased by US$610 million and includes:

-- US$114 million - unfavourable fixed cost dilution at Olympic Dam as a result of the smelter maintenance campaign;

-- US$106 million - increased labour and contractor costs at Olympic Dam, primarily to support operating stability projects and expansion studies;

-- US$206 million - a change in estimated recoverable copper contained in the Escondida sulphide leach pad which benefited costs in the prior period; and

19

   --    US$195 million - ore inventory movements at Escondida and Pampa Norte. 

Non-cash costs (including development stripping) decreased by US$253 million reflecting:

-- increased waste movement at Escondida and Pampa Norte reflected in higher capitalised stripping; and

-- increased underground mine capitalisation at Olympic Dam as mining expands into the Southern Mine Area.

As a result, unit costs at our operated copper assets increased by 17 per cent to US$1.27 per pound during the December 2017 half year including a 16 per cent increase at Escondida to US$1.06 per pound partially due to unfavourable exchange rate movements. Escondida unit cost guidance for the 2018 financial year remains unchanged at approximately US$1.00 per pound (based on an exchange rate of USD/CLP 663).

(1) Average realised price: iron ore US$57/wmt, FOB (2016: US$55/wmt, FOB).

(2) Other includes: fuel and energy; non-cash; asset sales.

Total iron ore production for the December 2017 half year was in line with the prior period at 117 Mt(x) , as record production at Jimblebar and Mining Area C was offset by the impact of lower opening stockpile levels following the Mt Whaleback fire in June 2017 and planned maintenance.

BHP received regulatory approval to increase capacity at its Port Hedland operations to 290 Mtpa (100 per cent basis) on 16 February 2018 and expects to reach this run rate by the end of the 2019 financial year.

Controllable cash costs decreased by US$137 million, primarily due to continued reductions in labour and contractor costs.

WAIO unit costs declined by one per cent to US$14.90 per tonne during the December 2017 half year, despite the impact of a stronger Australian dollar. In local currency terms, WAIO unit costs declined by six per cent.

Unit cost guidance for the 2018 financial year remains unchanged at less than US$14 per tonne (based on an exchange rate of AUD/USD 0.75). In the medium term, we expect to lower our unit costs to less than US$13 per tonne.

South Flank feasibility study is progressing, with the project expected to be submitted for Board approval in the middle of the 2018 calendar year. The capital cost for the 80 Mtpa (100 per cent basis) sustaining mine is now expected to be around US$45 per tonne, reflecting a stronger Australian dollar and updated estimates as the project planning has progressed. The capital cost fits within WAIO's previously indicated average sustaining capital expenditure of US$4 per tonne (plus or minus 50 per cent in any given year) over the medium term. The South Flank project, which will leverage and expand the existing Mining Area C hub, will increase WAIO's average Fe grade from 61 per cent to 62 per cent and lump proportion for our overall product mix from approximately 25 per cent to 35 per cent, supporting WAIO's ability to benefit from sustained higher premiums for lump and higher quality fines.

Guidance for production and unit costs for the 2018 financial year is also detailed on page 3. Capital expenditure and project information is detailed on pages 4 and 5.

(1) Average realised price: hard coking coal US$182/t (2016: US$179/t); weak coking coal US$121/t (2016: US$122/t); thermal coal US$87/t (2016: US$74/t).

(2) Other includes: fuel and energy; asset sales; ceased and sold operations; other items (including profit from equity accounted investments).

Metallurgical coal production decreased by four per cent to 20 Mt(x) as record production at four Queensland Coal mines was offset by lower volumes at Broadmeadow (roof conditions; expected to continue through the March 2018 quarter) and Blackwater (geotechnical issues triggered by wet weather). Guidance for the 2018 financial year has been reduced to between 41 and 43 Mt.

Energy coal production increased by four per cent to 14 Mt(x) as a strong performance at New South Wales Energy Coal (NSWEC) was offset by the impacts of wet weather at Cerrejón.

Controllable cash costs increased by US$191 million and includes:

-- US$134 million - primarily reflects unfavourable fixed cost dilution from reduced volumes at Broadmeadow and Blackwater, and compensatory increased production from higher cost pits, at BHP Billiton Mitsubishi Alliance (BMA); and

-- US$11 million - increased contractor activity partially offset by improved ultra-class truck productivity at NSWEC.

Queensland Coal unit costs increased by 26 per cent to US$71 per tonne in the December 2017 half year, including the impact of a stronger Australian dollar. Unit costs for the 2018 financial year are now expected to be US$66 per tonne (based on an exchange rate of AUD/USD 0.75), an increase from previous guidance of US$59 per tonne, reflecting reduced Broadmeadow and Blackwater volumes, increased production from higher cost pits and rising inflationary pressures. Unit costs for the second half of the 2018 financial year are expected to be US$63 per tonne. In the medium term, we expect to lower our unit costs to approximately US$54 per tonne.

NSWEC unit costs increased by four per cent to US$48 per tonne in the December 2017 half year due to the impact of a stronger Australian dollar. Unit cost guidance for the 2018 financial year remains unchanged at US$46 per tonne (based on an exchange rate of AUD/USD 0.75). In the medium term, we expect to lower our unit costs further to approximately US$40 per tonne.

Group and unallocated items

Underlying EBITDA loss for Group and unallocated items increased by US$68 million to US$89 million in the December 2017 half year, as a strong performance at Nickel West was more than offset by increased corporate spend on technology projects and unfavourable exchange rate impacts on corporate provision balances.

Nickel West's Underlying EBITDA increased by 92 per cent to US$71 million for the December 2017 half year, predominantly due to higher prices and improved mill utilisation and concentrator recoveries.

The Financial Report on pages 27 to 48 has been prepared in accordance with IAS 34 'Interim Financial Reporting'. This news release including the financial information is unaudited. Variance analysis relates to the relative financial and/or production performance of BHP and/or its operations during the December 2017 half year compared with the December 2016 half year, unless otherwise noted. Operations includes operated and non-operated assets, unless otherwise noted.

The following abbreviations may have been used throughout this report: barrels (bbl); billion cubic feet (bcf); barrels of oil equivalent (boe); billion tonnes (Bt); 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 ounces per annum (Mozpa); 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 ounces per annum (kozpa); 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:

(i) We use other financial measures (each of which is calculated with reference to IFRS measures) to assess our performance, which are defined below:

   --     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 Group at the reporting date.

(ii) We use various alternate performance measures to reflect our underlying performance. Our two primary measures of performance are Underlying attributable profit and Underlying EBITDA.

We believe these alternate performance measures provide useful information, but should not be considered as an indication of, or as a substitute for, Attributable profit and other statutory measures as an indicator of actual operating performance or as an alternative to cash flow as a measure of liquidity.

We consider Underlying attributable profit to be a key measure that provides insight on the amount of profit available to distribute to shareholders, which aligns to our purpose as outlined in Our Charter. Underlying attributable profit is also the key performance indicator against which short-term incentive outcomes for our senior executives are measured and, in our view, is a relevant measure to assess the financial performance of BHP for this purpose.

Underlying EBITDA is the key alternate performance measure that management uses internally to assess the performance of the Group's segments and make decisions on the allocation of resources. In the Group's view, this is more relevant to capital intensive industries with long-life assets.

-- Underlying attributable profit is Profit after taxation attributable to owners of the BHP Group (also referred to as 'Attributable profit') excluding any exceptional items attributable to the owners of the BHP Group.

-- Underlying EBITDA is Earnings before net finance costs, depreciation, amortisation and impairments, taxation expense, and exceptional items. Underlying EBITDA includes net finance costs and taxation expense, depreciation, amortisation and impairments related to equity accounted investments of US$318 million (2016: US$267 million) and excludes exceptional items of US$137 million (2016: US$48 million) related to share of loss from equity accounted investments.

-- Underlying EBIT is Underlying EBITDA, including depreciation, amortisation and impairments of US$4,336 million for the December 2017 half year (2016: US$3,914 million). Underlying EBIT includes net finance costs and taxation expense of US$211 million (2016: US$156 million) related to equity accounted investments and excludes exceptional items of US$137 million (2016: US$48 million) related to share of loss from equity accounted investments.

(iii) Further alternate performance measures are defined as follows:

-- Adjusted effective tax rate - comprises Total taxation expense excluding exceptional items and exchange rate movements included in taxation expense divided by Profit before taxation and exceptional items. Management believes this measure provides useful information regarding the tax impacts from underlying operations.

-- Net operating assets - represents operating assets net of operating liabilities including the carrying value of equity accounted investments and predominantly excludes cash balances, loans 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.

26

-- Operating assets free cash flow - comprises net operating cash flows adjusted for dividends received, net interest received/(paid) and net income tax and royalty-related taxation refunded/(paid) less net investing cash flows. Dividends received, net interest and net income tax and royalty-related taxation are not allocated to operating asset free cash flow as financing structures and tax regimes differ across the Group's assets and substantial components of the Group's interest and tax charges are levied at a Group level rather than an operational level.

-- Underlying basic earnings per share - represents underlying attributable profit divided by the weighted average number of basic shares.

-- Underlying EBITDA margin - comprises Underlying EBITDA excluding third party product EBITDA, divided by revenue excluding third party product revenue.

-- Underlying return on capital employed (ROCE) - represents annualised attributable profit after tax excluding exceptional items and net finance costs (after tax) divided by average capital employed. Average capital employed is calculated as the average of net assets less net debt for the last two reporting periods.

The method of calculation of the Principal factors that affect Underlying EBITDA is as follows:

References to operation/s in each Principal factor excludes equity accounted investments which are included within 'Other'.

-- Change in sales prices - Change in average realised price for each operation from the corresponding period to the current period, multiplied by current period volumes.

-- Price-linked costs - Change in price-linked costs for each operation from the corresponding period to the current period, multiplied by current period volumes.

-- Productivity volumes - Change in volumes for each operation not included in the Growth category from the corresponding period to the current period, multiplied by the prior year Underlying EBITDA margin. Used to determine changes in productivity in footnote (iv).

-- Growth volumes - Volume - Growth comprises Underlying EBITDA for operations that are new or acquired in the current period minus Underlying EBITDA for operations that are new or acquired in the corresponding period, change in volumes for operations identified as a Growth project from the corresponding period to the current period multiplied by the prior year Underlying EBITDA margin, and change in volume for our petroleum assets from the corresponding period to the current period multiplied by the prior year Underlying EBITDA margin.

-- 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. Used to determine changes in productivity in footnote (iv).

-- Operating cash costs - Change in total costs, other than price-linked costs, exchange rates, inflation on costs, fuel and energy costs, non-cash costs and one-off items as defined below for each operation from the corresponding period to the current period.

Forward-looking statements

This release contains forward-looking statements, including statements regarding: trends in commodity prices and currency exchange rates; demand for commodities; plans, strategies and objectives of management; closure or divestment of certain operations or facilities (including associated costs); anticipated production or construction commencement dates; capital costs and scheduling; operating costs and shortages of materials and skilled employees; anticipated productive lives of projects, mines and facilities; provisions and contingent liabilities; tax and regulatory developments.

Forward-looking statements can be identified by the use of terminology such as 'intend', 'aim', 'project', 'anticipate', 'estimate', 'plan', 'believe', 'expect', 'may', 'should', 'will', 'continue', 'annualised' or similar words. These statements discuss future expectations concerning the results of operations or financial condition, or provide other forward-looking statements.

These forward-looking statements are not guarantees or predictions of future performance, and involve known and unknown risks, uncertainties and other factors, many of which are beyond our control, and which may cause actual results to differ materially from those expressed in the statements contained in this release. Readers are cautioned not to put undue reliance on forward-looking statements.

For example, our future revenues from our operations, projects or mines described in this release will be based, in part, upon the market price of the minerals, metals or petroleum produced, which may vary significantly from current levels. These variations, if materially adverse, may affect the timing or the feasibility of the development of a particular project, the expansion of certain facilities or mines, or the continuation of existing operations.

Other factors that may affect the actual construction or production commencement dates, costs or production output and anticipated lives of operations, mines or facilities include our ability to profitably produce and transport the minerals, petroleum and/or metals extracted to applicable markets; the impact of foreign currency exchange rates on the market prices of the minerals, petroleum or metals we produce; activities of government authorities in some of the countries where we are exploring or developing these projects, facilities or mines, including increases in taxes, changes in environmental and other regulations and political uncertainty; labour unrest; and other factors identified in the risk factors discussed in BHP's filings with the U.S. Securities and Exchange Commission (the 'SEC') (including in Annual Reports on Form 20-F) which are available on the SEC's website at www.sec.gov.

Except as required by applicable regulations or by law, the Group does not undertake any obligation to publicly update or review any forward-looking statements, whether as a result of new information or future events.

Past performance cannot be relied on as a guide to future performance.

Notes to the Financial Information

   1.   Basis of preparation 

This general purpose financial report for the half year ended 31 December 2017 is unaudited and has been prepared in accordance with IAS 34 'Interim Financial Reporting' as issued by the International Accounting Standards Board (IASB) and as adopted by the European Union (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 2017 are not the statutory accounts of the 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 2017 annual financial statements contained within the Annual Report of the Group.

The directors have made an assessment of the Group's ability to continue as a going concern and consider it appropriate to adopt the going concern basis of accounting in preparing the half year financial statements.

The following new significant accounting standards are not yet effective, but may have an impact on the Group in financial years commencing on or after 1 January 2018:

 
                                                                          Application

US tax reform

On 22 December 2017, the US President signed the Tax Cuts and Jobs Act (the TCJA) into law. The TCJA (effective 1 January 2018) includes a broad range of tax reforms affecting the Group, including, but not limited to, a reduction in the US corporate tax rate from 35 per cent to 21 per cent and changes to international tax provisions.

39

   2.   Exceptional items (continued) 

Following enactment of the TCJA, the Group has recognised an exceptional income tax charge of US$1,828 million, primarily relating to the reduced US corporate income tax rate, which resulted in re-measurement of the Group's deferred tax position and impairment of foreign tax credits due to reduced forecast utilisation, together with tax charges on the deemed repatriation of accumulated earnings of non-US subsidiaries.

(1) Comprising US$797 million repatriation tax and US$603 million of previously unrecognised tax credits.

(2) The profit from equity accounted investments and related expenses is net of income tax. This item removes the prima facie tax effect on such profits and related expenses.

The Group operates across many tax jurisdictions. Application of tax law can be complex and requires judgement to assess risk and estimate outcomes, particularly in relation to the Group's cross-border operations and transactions.

US tax reform

As per note 2 - Exceptional items, the impact of the TCJA has been included in the Financial Statements. The TCJA includes a number of complex provisions, the application of which are potentially subject to further implementation and regulatory guidance, and possible elections. Judgements are required about the application of the TCJA and its interaction with income tax accounting principles.

Key judgements and estimates

The Group has made preliminary determinations, based on currently available implementation guidance. However, judgements made are subject to risk and uncertainty, hence there is a possibility that changes in circumstances or future regulatory guidance may alter the judgements made, which may potentially impact the amount of deferred or current taxes recognised on the balance sheet and the amount of other tax balances not yet recognised.

The significant judgements and estimates include:

-- The TCJA requires mandatory deemed repatriation of post-1986 undistributed earnings and profits from specific non-US subsidiaries. In assessing the potential tax charge, the Group has made certain assumptions as to offsets available under the TCJA, including the use of available foreign tax credits to partially offset the deemed repatriation tax liability.

-- The US will continue to tax foreign income from partnerships on a worldwide basis with the ability to offset US tax liabilities on foreign earnings with a credit for taxes paid in foreign jurisdictions. The reduction in the US corporate tax rate and the revised differential in tax rates with other jurisdictions impacts the forecasted utilisation of these foreign tax credits. The Group has made certain assumptions as to the utilisation of available foreign tax credits based on an assessment of probable future US income tax.

Where further clarifying regulatory guidance is issued, this may potentially impact the assumptions made and result in a different outcome.

   6.   Deferred tax balances 

The movement for the period in the Group's net deferred tax position is as follows:

(1) 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 Limited Employee Equity Trust.

(2) For the purposes of calculating diluted earnings per share, the effect of 15 million of dilutive shares has been taken into account for the half year ended 31 December 2017 (31 December 2016: 14 million shares; 30 June 2017: 13 million shares). The Group's only potential dilutive ordinary shares are share awards granted under employee share ownership plans. Diluted earnings per share calculation excludes instruments which are considered antidilutive.

At 31 December 2017, there are no instruments which are considered antidilutive (31 December 2016: nil; 30 June 2017: nil).

(3) Each American Depositary Share represents twice the earnings for BHP ordinary shares.

(1) 5.5 per cent dividend on 50,000 preference shares of GBP1 each determined and paid annually (31 December 2016: 5.5 per cent; 30 June 2017: 5.5 per cent).

Subsequent to the half year ended 31 December 2017, on 20 February 2018, BHP Billiton Limited and BHP Billiton Plc determined an interim dividend of 55 US cents per share (US$2,928 million), which will be paid on 27 March 2018.

At 31 December 2017, 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 2017 (31 December 2016: nil, 30 June 2017: nil).

Dividends paid during the period differs from the amount of dividends paid in the Cash Flow Statement as a result of foreign exchange gains and losses relating to the timing of equity distributions between the record date and the payment date.

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 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.

   9.   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.

   9.   Financial risk management - Fair values (continued) 

For financial assets and liabilities carried at fair value, the Group uses the following to categorise the method used:

                                         (i.e. as unquoted 
                                         prices) or 
                                         indirectly 
                                         (i.e. derived 
                                         from prices). 
 

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 2017: US$3,019 million) of fixed rate debt not swapped to floating rate, the fair value at 31 December 2017 was US$3,684 million (30 June 2017: US$3,523 million) included within Notes and debentures in the table below.

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.

   9.   Financial risk management - Fair values (continued) 

(1) All of the Group's financial assets and financial liabilities recognised at fair value were valued using market observable inputs categorised as Level 2 with the exception of the specified items in the following footnotes.

(2) Includes other derivative contracts of US$268 million (30 June 2017: US$365 million) categorised as Level 3.

(3) Includes other investments held at fair value through profit or loss (US Treasury Notes) of US$115 million categorised as Level 1 (30 June 2017: US$97 million).

(4) Includes shares and other investments available for sale of US$80 million (30 June 2017: US$70 million) categorised as Level 3.

(5) Excludes input taxes of US$300 million (30 June 2017: US$262 million) included in other receivables.

(6) Includes net assets of US$7 million (30 June 2017: net liabilities of US$7 million) natural gas futures contracts used by the Group to mitigate price risk designated as cash flow hedges.

(7) Excludes input taxes of US$148 million (30 June 2017: US$134 million) included in other payables.

(8) All interest bearing liabilities, excluding finance leases, are unsecured.

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$348 million (30 June 2017: US$435 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$272 million (30 June 2017: US$370 million).

The potential effect of using reasonably possible alternative assumptions in these models, based on a change in the most significant input, commodity prices, by an increase/(decrease) of 10 per cent while holding all other variables constant will increase/(decrease) profit after taxation by US$50 million (30 June 2017: US$62 million).

10. 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 communities of Bento Rodrigues, Gesteira and Paracatu and impacting other communities downstream (the Samarco dam failure).

Samarco is jointly owned by BHP Billiton Brasil Ltda (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 relating to the Samarco dam failure incurred directly by BHP Billiton Brasil or other BHP entities are recognised 100 per cent in the Group's results.

Equity accounted investment in Samarco

BHP Billiton Brasil's investment in Samarco remains at US$ nil. BHP Billiton Brasil provided US$50 million funding under a working capital facility during the period and recognised additional share of losses of US$50 million. No dividends have been received by BHP Billiton Brasil 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 2017, 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 2017 Annual Report, subject to the updates set out below:

Environment and socio-economic remediation

Framework Agreement

On 2 March 2016, BHP Billiton Brasil, together with Samarco and Vale, entered into a Framework Agreement with the Federal Government of Brazil, the states of Espírito Santo and Minas Gerais and certain other public authorities to establish a foundation (Fundação Renova) that will develop and execute environmental and socio-economic programs to remediate and provide compensation for damage caused by the Samarco dam failure.

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 2017, BHP Billiton Brasil has recognised a provision of US$1.0 billion before tax and after discounting (30 June 2017: US$1.1 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 and funding amounts required under the Framework Agreement including further technical analysis required under the Preliminary Agreement, the outcome of the ongoing negotiations with the Federal and State Prosecutors, 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.

For the half year ended 31 December 2017, BHP Billiton Brasil has paid US$154 million to allow for the continuation of reparatory and compensatory programs in relation to the Framework Agreement and a further US$2 million for dam stabilisation, with the total US$156 million offset against the provision for the Samarco dam failure.

On 22 December 2017, BHP Billiton Brasil announced a further US$133 million to support Fundação Renova, in the event Samarco does not meet its funding obligations under the Framework Agreement. Any support to the Fundação Renova provided by BHP Billiton Brasil will be offset against the provision for the Samarco dam failure.

Preliminary Agreement

On 18 January 2017, BHP Billiton Brasil together with Samarco and Vale, 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 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.

Under the Preliminary Agreement, BHP Billiton Brasil, Samarco and Vale agreed interim security (Interim Security) comprising R$1.3 billion (approximately US$395 million) in insurance bonds, R$100 million (approximately US$30 million) in liquid assets, a charge of R$800 million (approximately US$240 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.

52

10. Significant events - Samarco dam failure (continued)

The Interim Security was provided to the 12th Civil/Agricultural Federal Court of Minas Gerais on 24 January 2017 and will remain in place until the earlier of 20 April 2018 and the date that a settlement arrangement is agreed between the Federal Prosecutors, BHP Billiton Brasil, Samarco and Vale.

On 16 November 2017, BHP Billiton Brasil, together with Samarco and Vale, entered into an Amendment Agreement with the Federal Prosecutors' Office in Brazil (Federal Prosecutors) and the Minas Gerais State Prosecutors Office (State Prosecutors). The Amendment Agreement amends the Preliminary Agreement by providing for the State Prosecutors to become party to the Preliminary Agreement, in addition to including provisions for additional community consultation and replacing one of the socioeconomic experts appointed in the Preliminary Agreement to advise the Federal Prosecutors.

In light of the ongoing negotiations, BHP Billiton Brasil, Samarco and Vale, together with the Federal and State Prosecutors, requested, and the 12th Civil/Agricultural Federal Court of Minas Gerais approved, an extension to the date for negotiations towards a settlement agreement in relation to the R$20 billion (approximately US$6 billion) public civil claim and R$155 billion (approximately US$47 billion) Federal Public Prosecution Office claim to 20 April 2018. During the extension period, the Interim Security and the current suspension of legal proceedings and injunctions under the Preliminary Agreement (see below) will remain in place. The parties will use best efforts to achieve a partial settlement agreement, focused mainly on including prosecutor and community participation into the governance structure of the Framework Agreement, by 20 April 2018.

Legal

The following matters are disclosed as contingent liabilities:

BHP Billiton Brasil is among the companies named as defendants in a number of legal proceedings initiated by individuals, non-governmental organisations (NGOs), corporations and governmental entities in Brazilian federal and state courts following the Samarco dam failure. The other defendants include Vale, Samarco and the Foundation. The lawsuits include claims for compensation, environmental rehabilitation and violations of Brazilian environmental and other laws, among other matters. The lawsuits seek various remedies, including rehabilitation costs, compensation to injured individuals and families of the deceased, recovery of personal and property losses, moral damages and injunctive relief. 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.

In addition, governmental inquiries and investigations relating to the Samarco dam failure have been commenced by numerous agencies of the Brazilian government and are ongoing.

Ultimately, all legal matters disclosed as contingent liabilities could have a material adverse impact on BHP's business, competitive position, cash flows, prospects, liquidity and shareholder returns.

As at 31 December 2017, 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 2017 Annual Report, subject to the updates set out below:

R$20 billion Public Civil claim

Among the claims brought against BHP Billiton Brasil, is a public civil claim commenced by the Federal Government of Brazil, states of Espírito Santo, Minas Gerais and other public authorities on 30 November 2015, seeking the establishment of a fund of up to R$20 billion (approximately US$6 billion) in aggregate for clean-up costs and damages.

While a final decision by the 12th Civil/Agricultural Federal Court of Minas Gerais on the issue of ratification of the Framework Agreement is pending, the Preliminary Agreement suspends a R$1.2 billion (approximately US$360 million) injunction order under the R$20 billion Public Civil Claim.

The Preliminary Agreement also requests suspension of the R$20 billion (approximately US$6 billion) Public Civil Claim with a decision from the Court pending.

53

10. Significant events - Samarco dam failure (continued)

The R$1.2 billion (approximately US$360 million) injunction order may be reinstated if a settlement arrangement is not agreed by 20 April 2018.

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

BHP Billiton Brasil is among the defendants named in a claim brought by the Federal Public Prosecution Office on 3 May 2016, seeking R$155 billion (approximately US$47 billion) for reparation, compensation and moral damages in relation to the Samarco dam failure.

With regard to the Preliminary Agreement, the 12th Civil/Agricultural Federal Court of Minas Gerais suspended the Federal Public Prosecution Office claim, including a R$7.7 billion (approximately US$2.3 billion) injunction request. However, proceedings may be resumed if a settlement arrangement is not agreed by 20 April 2018. 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.

Class action complaint - shareholders

In February 2016, a putative class action complaint (Complaint) was filed in the U.S. District Court for the Southern District of New York on behalf of purchasers of American Depository Receipts of BHP Billiton Ltd and BHP Billiton Plc between 25 September 2014 and 30 November 2015 against BHP Billiton Ltd and BHP Billiton Plc and certain of its current and former executive officers and directors. The Complaint asserts claims under U.S. federal securities laws and indicates that the plaintiffs 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. On 14 October 2016, the defendants moved to dismiss the Complaint. In a decision of the District Court dated 28 August 2017, the claims were dismissed in part, including the claims against the current and former executive officers and directors.

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 BHP Billiton Ltd and BHP Billiton Plc.

Class action complaint - bond holders

On 14 November 2016, a putative class action complaint (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.

On 6 March 2017, the Complaint was amended to include BHP Billiton Ltd, BHP Billiton Plc, BHP Billiton Brasil Ltda and Vale S.A. and officers of Samarco, including four of Vale S.A. and BHP Billiton Brasil Ltda's nominees to the Samarco Board. On 5 April 2017, the plaintiff dismissed the claims against the individuals. The remaining corporate defendants filed a joint motion to dismiss the Complaint on 26 June 2017. That motion is pending before the Court.

The amount of damages sought by the plaintiff 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 BHP Billiton Ltd, BHP Billiton Plc and BHP Billiton Brasil Ltda.

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), Vale and Samarco in the Federal Court of Ponte Nova, Minas Gerais. On 3 March 2017, BHP Billiton Brasil filed its preliminary defences. 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 BHP Billiton Brasil, Vale and Samarco and certain of the individuals, a R$20 billion (approximately US$6 billion) asset freezing order application was made by the Federal Prosecutors. In July 2017, the Federal Court of Ponte Nova denied the Federal Prosecutors' application for an asset freezing order.

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 entities in Brazil or other jurisdictions.

BHP's and BHP Billiton Brasil'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.

BHP Insurance

BHP has third party liability insurance for claims related to the Samarco dam failure made directly against BHP Billiton Brasil or other BHP entities. External insurers have been advised of the Samarco dam failure and a formal claim has been prepared and submitted. At 31 December 2017, an insurance receivable has not been recognised for any potential recoveries under insurance arrangements.

Commitments

Under the terms of the Samarco joint venture agreement, BHP Billiton Brasil does not have an existing obligation to fund Samarco. For the half year ended 31 December 2017, BHP Billiton Brasil has provided US$50 million funding to support Samarco's operations and a further US$2 million for dam stabilisation, with undrawn amounts of US$24 million expiring as at 31 December 2017.

On 22 December 2017, BHP Billiton Brasil announced a new short-term facility of up to US$48 million to carry out ongoing repair works, maintain Samarco's facilities and support restart planning. Funds will be released to Samarco only as required and subject to the achievement of key milestones with amounts undrawn expiring at 30 June 2018.

Any additional requests for funding or future investment provided would be subject to a future decision, accounted for at that time.

11. Impairment of non-current assets - Onshore US

The Group is currently progressing a number of alternatives to exit our Onshore US assets for value. In light of this process, and the significant management judgement required when assessing the recoverable amount of assets, this note provides an update on the Group's assessment of the recoverability of the Onshore US assets.

Carrying amount

For impairment testing purposes, the goodwill arising from the Petrohawk acquisition in August 2011 is allocated to the Onshore US group of cash generating units (CGUs) which includes the Permian, Haynesville, Fayetteville, Black Hawk and Hawkville CGUs.

Impairment testing requirements

Impairment tests are carried out annually for goodwill. In addition, impairment tests for all assets and CGUs are performed when there is an indication of impairment. If the carrying amount of the asset or CGU exceeds its recoverable amount, the asset or CGU is impaired and an impairment loss is charged to the income statement so as to reduce the carrying amount to its recoverable amount.

Previously impaired assets and CGUs (excluding goodwill) are reviewed for possible reversal of previous impairment at each reporting date. Impairment reversal cannot exceed the carrying amount that would have been determined (net of depreciation) had no impairment loss been recognised for the asset or CGU.

At the half year, impairment tests, including for goodwill, are only performed if there is an indication of an impairment, or impairment reversal, since the end of the last financial year.

FY2017 Assessment

The annual impairment test of the Onshore US goodwill was performed in June after an assessment of the individual CGUs that it comprises. The recoverable amount of Onshore US at 30 June 2017 was calculated using fair value less cost of disposal (FVLCD) methodology.

The impairment testing at 30 June 2017 resulted in no impairment or reversals of impairment for Onshore US.

11. Impairment of non-current assets - Onshore US (continued)

HY2018 Assessment

For HY2018, an assessment was performed to determine whether there were any indicators of an impairment or impairment reversal since 30 June 2017. This included consideration of changes to market participant assumptions for the most significant estimates impacting asset recoverable amount valuations, including:

-- Production - the review of additional production data from BHP's wells and third party data did not indicate a significant change to the assumptions regarding production volumes;

-- Price - the Group has forecast some decreases in the long run crude oil and natural gas prices from the forecasts used at 30 June 2017. However, sensitivities performed on internal valuations for these changes did not give rise to an indicator of impairment; and

-- Discount rate - no indicators have arisen since 30 June 2017 that would indicate a significant change to the real post-tax rate of 7.0 per cent.

The enactment of the TCJA in the US on 22 December 2017 is expected to have a positive impact on the fair values of the Onshore US assets, largely due to the reduction in the rate of US corporate income tax. Ongoing analysis is being performed to assess the longer term potential impact of the TCJA on price forecasts, supply costs and the cost of capital.

Overall, the Group has assessed that there have been no changes that would indicate an impairment or impairment reversal since 30 June 2017. Accordingly, a recoverable amount determination at 31 December 2017 was not required to be performed.

Key judgements and estimates

In determining the recoverable amount of assets, in the absence of quoted market prices, estimates are made regarding the present value of future post-tax cash flows. These estimates require significant management judgement and are subject to risk and uncertainty that may be beyond the control of the Group. The estimates are made from the perspective of a market participant and include prices, future production volumes, operating costs, tax attributes and discount rates.

The calculation of FVLCD for Onshore US is most sensitive to changes in a market participant's perspective of crude oil and natural gas prices, production volumes and discount rates. In our FY2017 financial statements we identified reasonably possible changes that would result in the estimated recoverable amount being equal to the carrying amount of Onshore US, including goodwill.

Therefore there is a possibility that changes in circumstances will materially alter projections, which may impact the recoverable amount of assets at future reporting dates.

The Group's current divestment timeline includes the opening of data rooms and the receipt of bids prior to 30 June 2018, with evaluation and negotiation in the September quarter. Other divestment options continue to be considered. As the Group progresses alternative exit strategies, this may give rise to new information relevant to the assumptions used by management in the estimation of recoverable amount.

12. Subsequent events

No matters or circumstances have arisen since the end of the financial 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.

Principal Risks and Uncertainties

Due to the international scope of the Group's operated and non-operated assets and the industries in which it is engaged, there are a number of risk factors and uncertainties which could have an effect on the Group's results and operations over the next six months. The principal risks affecting the Group are described on pages 34 to 43 of the Group's Annual Report for the year ended 30 June 2017 (a copy of which is available on the Group's website at www.bhp.com) and are summarised below. There are no material changes in those risk factors for the remaining six months of the financial year except to the extent described in note 10 'Significant events - Samarco dam failure' of the half year financial statements and the 'Outlook' section.

Independent Review Report

Independent Auditors' review report of KPMG LLP ('KPMG UK') to the members of BHP Billiton Plc and of KPMG ('KPMG Australia') to the members of BHP Billiton Limited

Conclusions

For the purposes of these reports, the terms 'we' and 'our' denote KPMG UK in relation to UK responsibilities and reporting obligations to the members of BHP Billiton Plc, and KPMG Australia in relation to Australian responsibilities and reporting obligations to the members of BHP Billiton Limited.

BHP ('the Group') consists of BHP Billiton Plc, BHP Billiton Limited and the entities they controlled during the half year ended 31 December 2017.

We have reviewed the accompanying condensed financial statements of the Group for the half year ended 31 December 2017 ('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 12 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.

Review conclusion by KPMG UK

Based on our review, nothing has come to our attention that causes us to believe that the half year financial statements for the six months ended 31 December 2017 are not prepared, in all material respects, in accordance with IAS 34 'Interim Financial Reporting', as adopted by the European Union ('EU'), and the Disclosure Guidance and Transparency Rules ('the DTR') of the United Kingdom's Financial Conduct Authority ('the UK FCA').

Review conclusion by KPMG Australia

Based on our review, which is not an audit, we have not become aware of any matter that makes us believe that the half year financial statements, including the Directors' Declaration, of the Group are not in accordance with the Australian Corporations Act 2001, including:

a) Giving a true and fair view of the Group's financial position as at 31 December 2017 and of its performance for the half year ended on that date; and

b) Complying with Australian Accounting Standard AASB 134 'Interim Financial Reporting' and the Australian Corporations Regulations 2001.

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. We read the other information contained in the half year financial report and consider whether it contains any apparent misstatements or material inconsistencies with the information in the half year financial statements.

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 the auditor of BHP Billiton Limited, ASRE 2410 requires that KPMG Australia complies with the ethical requirements relevant to the audit of the annual consolidated 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.

63

Directors' responsibilities

The Directors are responsible for preparing the half year financial report which gives a true and fair view in accordance with:

-- The DTR of the UK FCA, and under those rules, in accordance with IAS 34 'Interim Financial Reporting' as adopted by the 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 responsibility is to express a conclusion on the half year financial statements in the half year financial report based on our review.

KPMG Australia's responsibility is to express a conclusion on the half year financial statements, including the Directors' Declaration based on our review.

The purpose of our review work and to whom we owe our responsibilities

KPMG UK's report is made solely to BHP Billiton Plc's members, as a body, 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 Australia's report is made solely to BHP Billiton Limited's members, as a body, in accordance with the Australian Corporations Act 2001. KPMG Australia has performed an independent review of the half year financial statements, including the 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, including the 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 2017 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 review work has been undertaken so that we might state to the members of each BHP Billiton Plc and BHP Billiton Limited those matters we are required to state to them in this report, and the further matters we are required to state to them in accordance with the terms agreed with each company, and for no other purpose. Accordingly, each of KPMG UK and KPMG Australia makes the following statement: to the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the company and the company's members as a body, for our review work, for our report, or for the conclusions we have reached.
