Accounting policies

Accounting policies

The principal accounting policies applied in the preparation of these financial statements are set out below. These policies have been consistently applied to all the years presented, except for the adoption of new and revised standards and interpretations.

Gold Fields Limited (the “Company” or “Gold Fields”) is a company domiciled in South Africa. The registration number of the Company is 1968/004880/06. The address of the Company is 150 Helen Road, Sandton, Johannesburg. The consolidated financial statements of the Company as at 31 December 2017 and 2016 and for each of the years in the three-year period ended 31 December 2017 comprise the Company and its subsidiaries (together referred to as the “Group” and individually as “Group entities”) as well as the Group’s share of the assets, liabilities, income and expenses of its joint operation and the Group’s interest in associates and its joint venture. The Group is primarily involved in gold mining.

1. BASIS OF PREPARATION

The financial statements of the Group have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”), the SAICA Financial Reporting Guides as issued by the Accounting Practices Committee and Financial Reporting Pronouncements as issued by the Financial Reporting Standards Council, as well as the requirements of the South African Companies Act. The consolidated financial statements have been prepared under the historical cost convention, as modified by available-for-sale financial assets, assets held for sale and financial assets and liabilities (including derivative instruments), which have been brought to account at fair value through profit or loss or through other comprehensive income.

As required by the United States Securities and Exchange Commission, the financial statements include the consolidated statements of financial position as at 31 December 2017 and 2016, and the consolidated income statements and statements of comprehensive income, changes in equity and cash flows for the years ended 31 December 2017, 2016 and 2015 and the related notes.

The consolidated financial statements were authorised for issue by the Board of Directors on 27 March 2018.

Standards, interpretations and amendments to published standards effective for the year ended 31 December 2017

During the financial year, the following new and revised accounting standards, amendments to standards and new interpretations were adopted by the Group:

Standard(s) Amendment(s) Interpretation(s)	Nature of the Change	Salient features of the changes	Impact on financial position or performance
IAS 7 Statement of cash flows	Amendments	•  The amendments require disclosures that enable users of financial statements to evaluate changes in liabilities arising from financing activities, including both changes arising from cash flow and non-cash changes.	No impact
IAS 12 Income taxes	Amendments	•  The amendments provide additional guidance on the existence of deductible temporary differences; and •  The amendments also provide additional guidance on the methods used to calculate future taxable profit to establish whether a deferred tax asset can be recognised.	No impact

Standards, interpretations and amendments to published standards which are not yet effective

Certain new standards, amendments and interpretations to existing standards have been published that apply to the Group’s accounting periods beginning on 1 January 2018 or later periods but have not been early adopted by the Group.

These standards, amendments and interpretations that are relevant to the Group are:

Standard(s) Amendment(s) Interpretation(s)	Nature of the Change		Salient features of the changes	Effective date*
IFRS 2 Share-based payments		Amendments	•  The amendments cover three accounting areas: -  Measurement of cash-settled share-based payments; -  Classification of share-based payments settled net of tax withholdings; and -  Accounting for a modification of a share-based payment from cash-settled to equity-settled. •  The amendment does not have a material impact on the Group.		1 January 2018
IFRS 9 Financial Instruments		New standard	•  This IFRS sets out requirements for recognising and measuring financial assets, financial liabilities and some contracts to buy or sell non-financial items. This standard replaces IAS 39 Financial Instruments. The Group will adopt IFRS 9 on 1 January 2018; •  This IFRS contains a new classification and measurement approach for financial assets that reflects the business model in which the assets are managed and their cash flow characteristics. The three principal		1 January 2018
			classification categories for financial assets are: measured at amortised cost, fair value through profit or loss (“FVTPL”) and fair value through other comprehensive income (“FVOCI”); •  Based on the Group’s assessment, the Group believes that the new classification if applied at 31 December 2017, would not have a significant impact on its accounting for financial assets. The Group’s available-for-sale financial assets will be designated at FVOCI; and •  The new measurement principles will not have a material impact on the Group.
IFRS 15 Revenue from contracts with customers		New standard	•  This IFRS introduces a new revenue recognition model for contracts with customers and establishes a comprehensive framework for determining whether, how much and when revenue is recognised. IFRS 15 also includes extensive new disclosure requirements; •  The Group has assessed the impact of adopting IFRS 15 and has determined the impact as follows: •  Revenue will be recognised when the customer takes control of the gold, copper and silver. The timing of recognition of revenue will no longer be when risks and rewards of ownership pass to the customer; •  The change in timing of revenue recognition will result in revenue at the South African and Australian operations being recognised on settlement date (date when control passes) and not contract date (previous date when risks and rewards of ownership pass). There is no change to the revenue recognition at any of the other operations given that the date of control is the same date as when risks and rewards of ownership pass. The change in timing of revenue recognition for the South African and Australian operations will be that revenue will be recognised approximately two days later than it currently is recognised. As approximately 0.3% of 2017 revenue will		1 January 2018
			now be recognised in 2018, the adoption of IFRS 15 will not have a material impact on the revenue of the Group; and •  The Group will adopt IFRS 15 using the cumulative effect method, with the effect of initially applying this standard at the date of initial application (i.e. 1 January 2018). As a result, the Group will not apply the requirements of IFRS 15 to the comparative periods presented.
IFRS 16 Leases		New standard	•  This IFRS sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract, i.e. the customer (‘lessee’) and the supplier (‘lessor’); •  IFRS 16 replaces the previous leases Standard, IAS 17 Leases, and related Interpretations; •  IFRS 16 has one model for lessees which will result in almost all leases being included on the statement of financial position. No significant changes have been included for lessors; and •  Management has commenced compiling a list of all potential leases and is in the process of reviewing all such contracts in order to assess the impact the standard will have on the Group.	1 January 2019
IFRIC 23 Uncertainty over Income Tax Treatments		New interpretation	•  This interpretation clarifies the accounting for income tax treatments that have yet to be accepted by tax authorities; •  IFRIC 23 specifically clarifies how to incorporate this uncertainty into the measurement of tax as reported in the financial statements; •  IFRIC 23 does not introduce any new disclosures but reinforces the need to comply with existing disclosure requirements about judgements made, assumptions and other estimates used and the potential impact of uncertainties that are not reflected •  The interpretation will not have a material impact on the Group.	1 January 2019

* Effective date refers to annual period beginning on or after said date.

Significant accounting judgements and estimates

Use of estimates: The preparation of the financial statements in accordance with IFRS requires the Group’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The determination of estimates requires the exercise of judgement based on various assumptions and other factors such as historical experience, current and expected economic conditions, and in some cases actuarial techniques. Actual results could differ from those estimates.

The more significant areas requiring the use of management estimates and assumptions relate to mineral reserves and resources that are the basis of future cash flow estimates used for impairment assessments and units-of-production depreciation and amortisation calculations, asset impairments, production start date, estimates of recoverable gold and other materials in heap leach and stockpiles inventories, write-downs of inventory to net realisable value, provision for environmental rehabilitation costs, provision for silicosis settlement costs, income taxes, share-based payments, the fair value and accounting treatments of derivative financial instruments, contingencies and business combinations.

Estimates and judgements are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances.

The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the financial year are discussed below.

Mineral reserves and resources estimates

Mineral reserves are estimates of the amount of product, inclusive of diluting materials and allowances for losses, which can be economically and legally extracted from the Group’s properties, as determined by life-of-mine schedules or pre-feasibility studies.

Mineral resources are estimates, based on specific geological evidence and knowledge, including sampling, of the amount of product in situ, for which there is a reasonable prospect for eventual legal and economic extraction.

In order to calculate the reserves and resources, estimates and assumptions are required about a range of geological, technical and economic factors, including but not limited to quantities, grades, production techniques, recovery rates, production costs, capital expenditure, transport costs, commodity demand, commodity prices and exchange rates.

Estimating the quantity and grade of the mineral reserves and resources is based on exploration and sampling information gathered through appropriate techniques (primarily diamond drilling, reverse circulation drilling, air-core and sonic drilling), surface three-dimensional reflection seismics, ore body faces modelling, structural modelling, geological mapping, detailed ore zone wireframes and geostatistical estimation. This process may require complex and difficult geological judgements and calculations to interpret the data.

The Group is required to determine and report on the mineral reserves and resources in accordance with the South African Mineral Resource Committee (“SAMREC”) code on an annual basis.

Estimates of mineral reserves and resources may change from year to year due to the change in economic, regulatory, infrastructural or social assumptions used to estimate ore reserves and resources, and due to additional geological data becoming available.

Changes in reported proven and probable reserves may affect the Group’s financial results and position in a number of ways, including the following:

• The recoverable amount used in the impairment calculations may be affected due to changes in estimated cash flows or timing thereof;

• Amortisation and depreciation charges to profit or loss may change as these are calculated on the units-of-production method, or where the useful economic lives of assets change;

• Provision for environmental rehabilitation costs may change where changes in ore reserves affect expectations about the timing or cost of these activities; and

• The carrying value of deferred tax assets may change due to changes in estimates of the likely recovery of the tax benefits.

Changes in reported measured and indicated resources may affect the Group’s financial results and position in a number of ways, including the following:

• The recoverable amount used in the impairment calculations may be affected due to changes in estimated market value of resources exclusive of reserves; and

• Amortisation and depreciation charges for the mineral rights asset at the Australian operations may change as a result of the change in the portion of mineral rights asset being transferred from the non-depreciable component to the depreciable component.

Carrying value of property, plant and equipment and goodwill

All mining assets are amortised using the units-of-production method where the mine operating plan calls for production from proved and probable mineral reserves.

Mobile and other equipment are depreciated over the shorter of the estimated useful life of the asset or the estimate of mine life based on proved and probable mineral reserves.

The calculation of the units-of-production rate of amortisation could be impacted to the extent that actual production in the future is different from current forecast production based on proved and probable mineral reserves. This would generally result from the extent that there are significant changes in any of the factors or assumptions used in estimating mineral reserves. These factors could include:

• Changes in proved and probable mineral reserves;

• Differences between actual commodity prices and commodity price assumptions;

• Unforeseen operational issues at mine sites;

• Changes in capital, operating, mining, processing and reclamation costs, discount rates and foreign currency exchange rates; and

• Changes in mineral reserves could similarly impact the useful lives of assets depreciated on a straight-line basis, where those lives are limited to the life of the mine.

The Group reviews and tests the carrying value of long-lived assets annually or when events or changes in circumstances suggest that the carrying amount may not be recoverable by comparing the recoverable amounts to these carrying values. In addition, goodwill is tested for impairment on an annual basis. Assets are grouped at the lowest level for which identifiable cash flows are largely independent of cash flows of other assets and liabilities. If there are indications that impairment may have occurred, estimates are prepared of recoverable amounts of each group of assets. The recoverable amounts of cash-generating units (“CGU”) and individual assets have been determined based on the higher of value-in-use and fair value less cost of disposal (“FVLCOD”) calculations. Expected future cash flows used to determine the value in use or FVLCOD of property, plant and equipment and goodwill are inherently uncertain and could materially change over time. They are significantly affected by a number of factors including reserves and production estimates, together with economic factors such as the gold and copper prices, discount rates, foreign currency exchange rates, resource valuations (determined based on comparable market transactions), estimates of costs to produce reserves and future capital expenditure.

An individual operating mine does not have an indefinite life because of the finite life of its reserves. The allocation of goodwill to an individual mine will result in an eventual goodwill impairment due to the wasting nature of the mine. In accordance with the provisions of IAS 36 Impairment of Assets, the Group performs its annual impairment review of goodwill at each financial year-end.

The Group generally used FVLCOD to determine the recoverable amount of each CGU.

Significant assumptions used in the Group’s impairment assessments (FVLCOD calculations) include:

1 Due to the availability of unredeemed capital for tax purposes over several years into the life of the South Deep mine, nominal cash flows are used for South Africa. In order to determine nominal cash flows in South Africa, costs are inflated by the current South African inflation rate. Cash flows for all other operations are in real terms and as a result are not inflated.

The FVLCOD calculations are very sensitive to the gold price assumptions and an increase or decrease in the gold price could materially change the FVLCOD.

Should there be a significant decrease in the gold price, the Group would take actions to assess the implications on the life-of-mine plans, including the determination of reserves and resources and the appropriate cost structure for the CGUs.

The carrying amount of property, plant and equipment at 31 December 2017 was US$4,892.9 million (2016: US$4,524.6 million and 2015: US$4,295.6 million). The carrying value of goodwill at 31 December 2017 was US$76.6 million (2016: US$317.8 million and 2015: US$295.3 million).

An impairment of US$277.8 million (2016: US$nil and 2015: US$nil) was recognised in respect of the South Deep CGU at 31 December 2017.

Production start date

The Group assesses the stage of each mine construction project to determine when a mine moves into the production stage. The criteria used to assess the start date are determined based on the unique nature of each mine construction project. The Group considers various relevant criteria to assess when the mine is substantially complete, ready for its intended use and moves into the production stage. Some of the criteria would include, but are not limited to the following:

• The level of capital expenditure compared to the construction cost estimates;

• Ability to produce metal in saleable form (within specifications); and

• Ability to sustain commercial levels of production of metal.

When a mine construction project moves into the production stage, the capitalisation of certain mine construction costs ceases and costs are either regarded as inventory or expensed, except for capitalisable costs related to mining asset additions or improvements, underground mine development, deferred stripping activities or ore reserve development.

Stockpiles, gold in process and product inventories

Costs that are incurred in or benefit the productive process are accumulated as stockpiles, gold in process, ore on leach pads and product inventories. Net realisable value tests are performed on a monthly basis for short-term stockpiles, gold in process and product inventories and at least annually for long-term stockpiles and represent the estimated future sales price of the product based on prevailing spot metals prices at the reporting date, less estimated costs to complete production and bring the product to sale. If any inventories are expected to be realised in the long term, estimated future sales prices are used for valuation purposes.

Stockpiles are measured by estimating the number of tonnes added and removed from the stockpile, the number of contained gold ounces based on assay data, and the estimated recovery percentage based on the expected processing method. Stockpile tonnages are verified by periodic surveys.

Although the quantities of recoverable metal are reconciled by comparing the grades of ore to the quantities of metals actually recovered (metallurgical balancing), the nature of the process inherently limits the ability to precisely monitor the recoverability levels. As a result, the metallurgical balancing process is constantly monitored and engineering estimates are refined based on actual results over time.

Variations between actual and estimated quantities resulting from changes in assumptions and estimates that do not result in write downs to net realisable value are accounted for on a prospective basis.

The carrying amount of total gold-in-process and stockpiles (non-current and current) at 31 December 2017 was US$305.4 million (2016: US$234.3 million).

Provision for environmental rehabilitation costs

The Group’s mining and exploration activities are subject to various laws and regulations governing the protection of the environment. The Group recognises management’s best estimate for the provision of environmental rehabilitation costs in the period in which they are incurred. Actual costs incurred in future periods could differ materially from the estimates. Additionally, future changes to environmental laws and regulations, life-of-mine estimates and discount rates could affect the carrying amount of this provision.

Refer note 25.1 of the consolidated financial statements for details of key assumptions used to estimate the provision.

The carrying amounts of the provision for environmental rehabilitation costs at 31 December 2017 was US$281.5 million (2016: US$283.1 million).

Provision for silicosis settlement costs

The Group has an obligation in respect of a possible settlement of the silicosis class action claims and related costs. The Group recognises management’s best estimate for the provision of silicosis settlement costs.

The ultimate outcome of the class action remains uncertain, with a possible failure to reach a settlement or to obtain the requisite court approval for a potential settlement. The provision is consequently subject to adjustment in the future, depending on the progress of the Working Group discussions, stakeholder engagements and the ongoing legal proceedings.

Refer notes 25.3 and 34 of the consolidated financial statements for further details.

The carrying amounts of the provision for silicosis settlement costs at 31 December 2017 was US$31.9 million (2016: US$nil).

Income taxes

The Group is subject to income taxes in numerous jurisdictions. Significant judgement is required in determining the liability for income taxes due to the complexity of legislation. There are many transactions and calculations for which the ultimate tax determination is uncertain during the ordinary course of business. The Group recognises liabilities for anticipated tax audit issues based on estimates of whether additional taxes will be due. Where the final tax outcome of these matters is different from the amounts that were initially recorded, such differences will impact the income tax and deferred tax provisions in the period in which such determination is made.

The Group recognises the future tax benefits related to deferred income tax assets to the extent that it is probable that the deductible temporary differences will reverse in the foreseeable future. Assessing the recoverability of deferred income tax assets requires the Group to make significant estimates related to expectations of future taxable income. Estimates of future taxable income are based on forecast cash flows from operations and the application of existing tax laws in each jurisdiction. To the extent that future cash flows and taxable income differ significantly from estimates, the ability of the Group to realise the net deferred tax assets recorded at the reporting date could be impacted.

Additionally, future changes in tax laws in the jurisdictions in which the Group operates could limit the ability of the Group to obtain tax deductions in future periods.

Carrying values at 31 December 2017:

• Deferred taxation liability: US$453.9 million (2016: US$458.6 million and 2015: US$482.2 million)

• Deferred taxation asset: US$72.0 million (2016: US$48.7 million and 2015: US$54.1 million)

• Taxation payable: US$77.5 million (2016: US$107.9 million)

Refer note 9 for details of unrecognised deferred tax assets.

Share-based payments

The Group issues equity-settled share-based payments to executive directors, certain officers and employees. The fair value of these instruments is measured at grant date, using the Black-Scholes and Monte Carlo simulation valuation models, which require assumptions regarding the estimated term of the option, share price volatility and expected dividend yield. While Gold Fields’ management believes that these assumptions are appropriate, the use of different assumptions could have a material impact on the fair value of the option granted and the related recognition of the share-based payments expense in the consolidated income statement. Gold Fields’ options have characteristics significantly different from those of traded options and therefore fair values may also differ.

The income statement charge from continuing operations for the year ended 31 December 2017 was US$26.8 million (2016: US$14.0 million and 2015: US$10.7 million).

Financial instruments

The estimated fair value of financial instruments is determined at discrete points in time, based on the relevant market information. The fair value is calculated with reference to market rates using industry valuation techniques and appropriate models. The carrying values of derivative financial instruments included in trade and other receivables at 31 December 2017 was US$25.0 million (2016: US$nil) and included in trade and other payables US$3.3 million (2016: US$nil).

Contingencies

By their nature, contingencies will only be resolved when one or more future events occur or fail to occur. The assessment of such contingencies inherently involves the exercise of significant judgement and estimates of the outcome of future events. Such contingencies include, but are not limited to environmental obligations, litigation, regulatory proceedings, tax matters and losses resulting from other events and developments.

When a loss is considered probable and reasonably estimable, a liability is recorded based on the best estimate of the ultimate loss. The likelihood of a loss with respect to a contingency can be difficult to predict and determining a meaningful estimate of the loss or a range of losses may not always be practicable based on the information available at the time and the potential effect of future events and decisions by third parties that will determine the ultimate resolution of the contingency. It is not uncommon for such matters to be resolved over many years, during which time relevant developments and new information is continuously evaluated to determine both the likelihood of any potential loss and whether it is possible to reasonably estimate a range of possible losses. When a loss is probable but a reasonable estimate cannot be made, disclosure is provided.

Refer note 34 for details on contingent liabilities.

Business combinations

Determination of whether a set of assets acquired and liabilities assumed constitute the acquisition of a business or asset may require the Group to make certain judgements as to whether or not the assets acquired and liabilities assumed include the inputs, processes and outputs necessary to constitute a business as defined in IFRS 3 Business Combinations. Based on an assessment of the relevant facts and circumstances, the Group concluded that the acquisition of the Gruyere Gold Project (refer note 15.2 for details of the acquisition) did not meet the criteria for accounting as a business combination and the transaction was accounted for as an acquisition of an asset at 31 December 2016.

2. CONSOLIDATION

2.1 Business combinations

The acquisition method of accounting is used to account for business combinations by the Group. The consideration transferred for the acquisition of a business is the fair value of the assets transferred, the liabilities incurred and the equity interests issued by the Group. The consideration transferred includes the fair value of any asset or liability resulting from a contingent consideration arrangement. Acquisition-related costs are expensed as incurred, other than those associated with the issue of debt or equity securities. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. On an acquisition-by-acquisition basis, the Group recognises any non-controlling interest in the acquiree either at fair value or at the non-controlling interest’s proportionate share of the acquiree’s net assets. Subsequently, the carrying amount of non-controlling interest is the amount of the interest at initial recognition plus the non-controlling interest’s share of the subsequent changes in equity.

The excess of the consideration transferred, the amount of any non-controlling interest in the acquiree and the acquisition date fair value of any previous equity interest in the acquiree over the fair value of the identifiable net assets acquired is recorded as goodwill. If this is less than the fair value of the net assets of the subsidiary acquired in the case of a bargain purchase, the difference is recognised directly in profit or loss.

If a transaction does not meet the definition of a business under IFRS, the transaction is recorded as an asset acquisition. Accordingly, the identifiable assets acquired and liabilities assumed are measured at the fair value of the consideration paid, based on their relative fair values at the acquisition date. Acquisition-related costs are included in the consideration paid and capitalised. Any contingent consideration payable that is dependent on the purchaser’s future activity is not included in the consideration paid until the activity requiring the payment is performed. Any resulting future amounts payable are recognised in profit or loss when incurred. No goodwill and no deferred tax asset or liability arising from the assets acquired and liabilities assumed are recognised upon the acquisition of assets.

2.2 Subsidiaries

Subsidiaries are all entities controlled by the Group. The Group controls an entity when it is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the relevant activities of the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Group until the date on which control ceases.

Inter-company transactions, balances and unrealised gains and losses on transactions between Group companies are eliminated. Accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the Group.

2.3 Transactions with non-controlling interests

The Group treats transactions with non-controlling interests that do not result in loss of control as transactions with equity owners of the Group. For purchases from non-controlling interests, the difference between any consideration paid and the relevant share acquired of the carrying value of net assets of the subsidiary is recorded in equity. Gains or losses on disposals to non-controlling interests are also recorded in equity.

2.4 Equity accounted investees

The Group’s interests in equity accounted investees comprise interests in associates and joint ventures.

Associates are those entities in which the Group has significant influence, but not control or joint control, over the financial and operating policies. Joint ventures are arrangements in which the Group has joint control, whereby the Group has rights to the net assets of the arrangement, rather than rights to its assets and obligations for its liabilities.

Interests in associates and joint ventures are accounted for using the equity method. They are recognised initially at cost, which includes transaction costs. Subsequent to initial recognition, the consolidated financial statements include the Group’s share of the profit or loss and the other comprehensive income of equity accounted investees, until the date on which significant influence or joint control ceases.

Results of associates and joint ventures are equity accounted using the results of their most recent audited financial statements. Any losses from associates or joint ventures are brought to account in the consolidated financial statements until the interest in such associates or joint ventures is written down to zero. Thereafter, losses are accounted for only insofar as the Group is committed to providing financial support to such associates or joint ventures.

The carrying value of an investment in associate and joint ventures represents the cost of the investment, including goodwill, a share of the post-acquisition retained earnings and losses, any other movements in reserves and any accumulated impairment losses. The carrying value is assessed annually for existence of indicators of impairment and if such exist, the carrying amount is compared to the recoverable amount, being the higher of value in use or fair value less cost of disposal. If an impairment in value has occurred it is recognised in profit or loss in the period in which the impairment arose.

2.5 Joint operations

A joint operation is a joint arrangement whereby the parties that have joint control of the arrangement have rights to the use of assets and obligations for the liabilities of the arrangement. The Group accounts for activities under joint operations by recognising in relation to the joint operation, the assets it controls and the liabilities it incurs, the expenses it incurs and the revenue from the sale or use of its share of the joint operations output.

3. FOREIGN CURRENCIES

3.1 Functional and presentation currency

Items included in the financial statements of each of the Group entities are measured using the currency of the primary economic environment in which the entity operates (“the functional currency”). The consolidated financial statements are presented in US Dollar.

3.2 Transactions and balances

Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions, and from the translation of monetary assets and liabilities denominated in foreign currencies, are recognised in profit or loss. Translation differences on available-for-sale equities are included in other comprehensive income.

3.3 Foreign operations

The results and financial position of all the Group entities (none of which has the currency of a hyperinflationary economy) that have a functional currency different from the presentation currency are translated into the presentation currency as follows:

Assets and liabilities are translated at the exchange rate ruling at the reporting date (ZAR/US$: 12.58; US$/A$: 0.77 (2016: ZAR/US$: 14.03; US$/A$: 0.72 and 2015: ZAR/US$: 15.10; US$/A$: 0.73)). Equity items are translated at historical rates. The income and expenses are translated at the average exchange rate for the year (ZAR/US$: 13.33; US$/A$: 0.77 (2016: ZAR/US$: 14.70; US$/A$: 0.75 and 2015: ZAR/US$: 12.68; US$/A$: 0.75)), unless this average was not a reasonable approximation of the rates prevailing on the transaction dates, in which case these items were translated at the rate prevailing on the date of the transaction. Exchange differences on translation are accounted for in other comprehensive income. These differences will be recognised in profit or loss upon realisation of the underlying operation.

On consolidation, exchange differences arising from the translation of the net investment in foreign operations (i.e. the reporting entity’s interest in the net assets of that operation), and of borrowings and other currency instruments designated as hedges of such investments, are taken to other comprehensive income. When a foreign operation is sold, exchange differences that were recorded in other comprehensive income are recognised in profit or loss as part of the gain or loss on disposal. If the Group disposes of part of its interest in a subsidiary but retains control, then the relevant proportion of the cumulative amount is reattributed to non-controlling interests. When the Group disposes of only part of an associate or joint venture while retaining significant influence or joint control, the relevant proportion of the cumulative amount is reclassified to profit or loss.

Goodwill and fair value adjustments arising on the acquisition of a foreign operation are treated as assets and liabilities of the foreign operation and are translated at each reporting date at the closing rate.

4. PROPERTY, PLANT AND EQUIPMENT

4.1 Mine development and infrastructure

Mining assets, including mine development and infrastructure costs and mine plant facilities, are recorded at cost less accumulated depreciation and accumulated impairment losses.

Expenditure incurred to evaluate and develop new orebodies, to define mineralisation in existing orebodies and to establish or expand productive capacity, is capitalised until commercial levels of production are achieved, at which times the costs are amortised as set out below.

Development of orebodies includes the development of shaft systems and waste rock removal that allows access to reserves that are economically recoverable in the future. Subsequent to this, costs are capitalised if the criteria for recognition as an asset are met.

4.2 Borrowing costs

Borrowing costs incurred in respect of assets requiring a substantial period of time to prepare for their intended future use are capitalised to the date that the assets are substantially completed.

4.3 Mineral and surface rights

Mineral and surface rights are recorded at cost less accumulated amortisation and accumulated impairment losses. When there is little likelihood of a mineral right being exploited, or the fair value of mineral rights has diminished below cost, an impairment loss is recognised in profit or loss in the year that such determination is made.

4.4 Land

Land is shown at cost and is not depreciated.

4.5 Other assets

Non-mining assets are recorded at cost less accumulated depreciation and accumulated impairment losses. These assets include the assets of the mining operations not included in mine development and infrastructure, borrowing costs, mineral and surface rights and land and all the assets of the non-mining operations.

4.6 Amortisation and depreciation of mining assets

Amortisation and depreciation is determined to give a fair and systematic charge to profit or loss taking into account the nature of a particular ore body and the method of mining that ore body. To achieve this, the following calculation methods are used:

• Mining assets, including mine development and infrastructure costs, mine plant facilities and evaluation costs, are amortised over the life of the mine using the units-of-production method, based on estimated proved and probable ore reserves;

• Stripping activity assets are amortised on a units-of-production method, based on the estimated proved and probable ore reserves of the ore body to which the assets relate; and

• The mineral rights asset at the Australian operations are divided at the respective operations into a depreciable and a non-depreciable component. The mineral rights asset is initially capitalised to the mineral rights asset as a non-depreciable component.

Subsequently, and on an annual basis, as part of the preparation of the updated reserve and resource statement and preparation of the updated life-of-mine plan, a portion of resources will typically be converted to reserves as a result of ongoing resource definition drilling, resultant geological model updates and subsequent mine planning. Based on this conversion of resources to reserves a portion of the historic cost is allocated from the non-depreciable component of the mineral rights asset to the depreciable component of the mineral rights asset. Therefore, the category of non-depreciable mineral rights asset is expected to reduce and will eventually be fully allocated within the depreciable component of the mineral rights asset.

Each operation typically comprises a number of mines and the depreciable component of the mineral rights asset is therefore allocated on a mine-by-mine basis at the operation and is transferred at this point to mine development and infrastructure and is then amortised over the estimated proved and probable ore reserves of the respective mine on the units-of-production method. The remaining non-depreciable component of the mineral rights asset is not amortised but, in combination with the depreciable component of the mineral rights asset and other assets included in the CGU, is evaluated for impairment when events and changes in circumstances indicate that the carrying amount may not be recoverable.

Proved and probable ore reserves reflect estimated quantities of economically recoverable reserves, which can be recovered in future from known mineral deposits.

Certain mining plant and equipment included in mine development and infrastructure is depreciated on a straight-line basis over the lesser of their estimated useful lives or life-of-mine.

Correction of amortisation for Australian mineral rights asset

During the year ended 31 December 2017, the Group corrected the amortisation methodology for the mineral rights asset at the Australian operations to reduce the level of estimation uncertainty required in calculating amortisation. Prior to the correction of methodology, the total mineral rights asset capitalised at the Australian operations was amortised on a units-of-production basis over a useful life that exceeded proved and probable reserves. The revised amortisation methodology for the mineral rights assets is set out on page 144.

At 1 January 2017, as a result of this correction of methodology, management identified an understatement of the amortisation and depreciation charge in prior periods. The understatement has been corrected by restating each of the affected financial statement line items for prior periods (refer note 40 for further details).

The impact of the correction of the amortisation methodology resulted in an increase in amortisation of US$5.7 million for the 2017 year.

4.7 Depreciation of non-mining assets

Non-mining assets are recorded at cost and depreciated on a straight-line basis over their current expected useful lives to their residual values as follows:

• Vehicles – 20%

• Computers – 33.3%

• Furniture and equipment – 10%

The assets’ useful lives, depreciation methods and residual values are reassessed at each reporting date and adjusted if appropriate.

4.8 Mining exploration

Expenditure on advances solely for exploration activities is charged against profit or loss until the viability of the mining venture has been proven. Expenditure incurred on exploration “farm-in” projects is written off until an ownership interest has vested. Exploration expenditure to define mineralisation at existing ore bodies is considered mine development costs and is capitalised until commercial levels of production are achieved.

Exploration activities at certain of the Group’s non-South African operations are broken down into defined areas within the mining lease boundaries. These areas are generally defined by structural and geological continuity. Exploration costs in these areas are capitalised to the extent that specific exploration programmes have yielded targets and/or results that warrant further exploration in future years.

4.9 Impairment

Recoverability of the carrying values of long-term assets or CGUs of the Group are reviewed annually or whenever events or changes in circumstances indicate that such carrying values may not be recoverable. To determine whether a long-term asset or CGU may be impaired, the higher of “value in use” (defined as: “the present value of future cash flows expected to be derived from an asset or CGU”) or “fair value less costs of disposal” (defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date”) is compared to the carrying value of the asset/CGU. Impairment losses are recognised in profit or loss.

A CGU is defined by the Group as the smallest identifiable group of assets that generates cash inflows that are largely independent of the cash inflows from other assets or groups of assets. Generally for the Group this represents an individual operating mine, including mines which are part of a larger mine complex. The costs attributable to individual shafts of a mine are impaired if the shaft is closed.

Exploration targets in respect of which costs have been capitalised at certain of the Group’s international operations are evaluated on an annual basis to ensure that these targets continue to support capitalisation of the underlying costs. Those that do not are impaired.

When any infrastructure is closed down during the year, any carrying value attributable to that infrastructure is impaired.

4.10 Gain or loss on disposal of property, plant and equipment

Any gain or loss on disposal of property, plant and equipment (calculated as the net proceeds from disposal less the carrying amount of the item) is recognised in profit or loss.

4.11 Leases

At the inception of an arrangement, the Group determines whether the arrangement contains a lease. Leases that transfer to the Group substantially all of the risks and rewards of ownership are classified as finance leases. All other leases are classified as operating leases and are not recognised in the statement of financial position.

Operating lease costs are charged against profit or loss on a straight-line basis over the period of the lease.

4.12 Deferred stripping

Production stripping costs in a surface mine are capitalised to property, plant and equipment if, and only if, all of the following criteria are met:

• It is probable that the future economic benefit associated with the stripping activity will flow to the entity;

• The entity can identify the component of the ore body for which access has been improved; and

• The costs relating to the stripping activity associated with that component can be measured reliably.

If the above criteria are not met, the stripping costs are recognised directly in profit or loss.

The Group initially measures the stripping activity asset at cost, this being the accumulation of costs directly incurred to perform the stripping activity that improves access to the identified component of ore.

After initial recognition, the stripping activity asset is carried at cost less accumulated amortisation and accumulated impairment losses.

5. GOODWILL

Goodwill is stated at cost less accumulated impairment losses. Goodwill on acquisition of equity accounted investees is tested for impairment as part of the carrying amount of the investment in associate or joint venture whenever there is any objective evidence that the investment may be impaired. Goodwill on acquisition of a subsidiary is assessed annually or whenever there are impairment indicators to establish whether there is any indication of impairment to goodwill. A write-down is made if the carrying amount exceeds the recoverable amount. Impairment losses on goodwill are not reversed. Gains and losses on the disposal of an entity include the carrying amount of goodwill allocated to the entity sold.

Goodwill is allocated to CGUs for the purpose of impairment testing. The allocation is made to those CGUs or groups of CGUs that are expected to benefit from the business combination in which the goodwill arose.

6. TAXATION

Income tax comprises current and deferred tax. Current tax and deferred tax is recognised in profit or loss except to the extent that it relates to a business combination, or items recognised directly in equity or in other comprehensive income.

Current tax is measured on taxable income at the applicable statutory rate substantively enacted at the reporting date.

Deferred taxation is provided on temporary differences existing at each reporting date between the tax values of assets and liabilities and their carrying amounts. Substantively enacted tax rates are used to determine future anticipated effective tax rates which in turn are used in the determination of deferred taxation.

Deferred taxation is not recognised for temporary differences on the initial recognition of assets or liabilities in a transaction that is not a business combination and that affects neither accounting nor taxable profit or loss and taxable temporary differences arising on the initial recognition of goodwill.

The measurement of deferred tax reflects the tax consequences that would follow the manner in which the Group expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities.

These temporary differences are expected to result in taxable or deductible amounts in determining taxable profits for future periods when the carrying amount of the asset is recovered or the liability is settled.

Deferred tax liabilities are generally recognised for all taxable temporary differences. Deferred tax liabilities are recognised for taxable temporary differences arising on investments in subsidiaries and equity accounted investees except where the reversal of the temporary difference can be controlled and it is probable that the difference will not reverse in the foreseeable future.

Deferred tax assets relating to the carry forward of unutilised tax losses and/or deductible temporary differences are recognised to the extent it is probable that future taxable profit will be available against which the unutilised tax losses and/or deductible temporary differences can be recovered. Deferred tax assets are reviewed at each reporting date and are adjusted if recovery is no longer probable.

Deferred tax assets and liabilities are offset if there is a legally enforceable right to offset current tax liabilities and assets, and they relate to taxes levied by the same tax authority on the same taxable entity, or on different tax entities, but they intend to settle current tax liabilities and assets on a net basis or their tax assets and liabilities will be realised simultaneously.

Except for Tarkwa, no provision is made for any potential taxation liability on the distribution of retained earnings by Group companies as it is probable that the related taxable temporary differences will not reverse in the foreseeable future.

7. INVENTORIES

Inventories are valued at the lower of cost and net realisable value. Gold on hand represents production on hand after the smelting process.

Cost is determined on the following basis:

• Gold on hand and gold-in-process is valued using weighted average cost. Cost includes production, amortisation and related administration costs;

• Heap leach and stockpiles inventories are valued using weighted average cost. Cost includes production, amortisation and related administration costs. The cost of materials on the heap leach and stockpiles from which metals are expected to be recovered in a period longer than 12 months is classified as non-current assets; and

• Consumable stores are valued at weighted average cost, after appropriate provision for redundant and slow-moving items.

Net realisable value is determined with reference to relevant market prices or the estimated future sales price of the product if it is expected to be realised in the long term.

8. FINANCIAL INSTRUMENTS

8.1 Non-derivative financial assets and liabilities

The Group classifies non-derivative financial assets into the following categories: financial assets at fair value through profit or loss, loans and receivables and available-for-sale financial assets.

The Group classifies non-derivative financial liabilities into the other financial liabilities category.

The Group initially recognises loans and receivables on the date they are originated. All other financial assets (including assets designated at fair value through profit or loss) are recognised initially on trade date, which is the date that the Group becomes a party to the contractual provisions of the instrument. The Group derecognises a financial asset when the contractual rights to the cash flows in a transaction in which substantially all the risks and rewards of the ownership of the financial asset are transferred. The Group derecognises a financial liability when its contractual obligations are discharged, cancelled or expire. Any interest in such transferred financial asset that is created or retained by the Group is recognised as a separate asset or liability. The particular recognition and measurement methods adopted are disclosed in the individual policy statements associated with each item.

A financial asset not classified as fair value through profit or loss is assessed at each reporting date to determine whether there is objective evidence that it is impaired. A financial asset is impaired if there is objective evidence of impairment as a result of one or more events that occurred after the initial recognition of the asset and the loss event(s) had an impact on the estimated future cash flows of that asset that can be estimated reliably. Objective evidence that financial assets are impaired includes default or delinquency by a debtor, indications that a debtor will enter bankruptcy, economic conditions that correlate with defaults or the disappearance of an active market for a security.

An impairment loss in respect of a financial asset measured at amortised cost is calculated as the difference between its carrying amount and the present value of the estimated future cash flows discounted at the asset’s original effective interest rate. Losses are recognised in profit or loss and reflected in an allowance against loans and receivables. When an event occurring after the impairment loss was recognised causes the amount of impairment loss to decrease, the decrease in impairment loss is reversed through profit or loss. A significant or prolonged decline in the fair value of an available-for-sale financial asset below its cost is objective evidence of impairment. Impairment losses on available-for-sale financial assets are recognised by reclassifying the losses accumulated in the fair value adjustment reserve in other comprehensive income to profit or loss. Impairment losses charged to profit or loss on available-for-sale financial assets are not reversed.

Financial assets and financial liabilities are offset and the net amount presented in the statement of financial position when, and only when, the Group has a currently legally enforceable right to offset the amounts and intends to settle them on a net basis or to realise the asset and settle the liability simultaneously.

8.1.1 Investments

Investments comprise (1) investments in listed companies which are classified as available-for-sale and are accounted for at fair value, with unrealised gains and losses subsequent to initial recognition recognised in other comprehensive income and included in other reserves, and released to profit or loss when the investments are sold or impaired; and (2) investments in unlisted companies which are accounted for at cost and adjusted for impairment where appropriate.

Purchases and sales of investments are recognised on the trade date, which is the date that the Group commits to purchase or sell the asset. Cost of purchase includes transaction costs. The fair value of listed investments is based on quoted bid prices.

On disposal or impairment of available-for-sale financial assets, cumulative unrealised gains and losses previously recognised in other comprehensive income are included in determining the profit or loss on disposal, or the impairment charge relating to, that financial asset, respectively, which is recognised in profit or loss.

8.1.2 Cash and cash equivalents

Cash and cash equivalents comprise cash on hand, demand deposits and short-term, highly liquid investments readily convertible to known amounts of cash and subject to insignificant risk of changes in value and are measured at amortised cost which is deemed to be fair value as they have a short-term maturity.

Bank overdrafts are included within current liabilities in the statement of financial position and within cash and cash equivalents in the statement of cash flows.

8.1.3 Trade receivables

Trade receivables are initially recognised at fair value and subsequently carried at amortised cost less allowance for impairment, except for trade receivables from provisional copper and gold concentrate sales. Estimates made for impairment are based on a review of all outstanding amounts at year-end. Irrecoverable amounts are written off during the year in which they are identified.

The trade receivables from provisional copper and gold concentrate sales are carried at fair value through profit or loss and are marked-to-market at the end of each period until final settlement occurs, with changes in fair value classified as provisional price adjustments and included as a component of revenue.

8.1.4 Trade payables

Trade payables are recognised initially at fair value and subsequently measured at amortised cost using the effective interest method.

8.1.5 Borrowings

Borrowings are recognised initially at fair value, net of transaction costs incurred, where applicable and subsequently measured at amortised cost using the effective interest method.

Borrowings are classified as current liabilities unless the Group has an unconditional right to defer settlement of the liability for at least 12 months after the reporting date.

Interest payable on borrowings is recognised in profit or loss over the term of the borrowings using the effective interest method.

Finance expense comprises interest on borrowings and environmental rehabilitation costs offset by interest capitalised on qualifying assets.

Cash flows from interest paid are classified under operating activities in the statement of cash flows.

8.2 Derivative financial instruments

The Group’s general policy with regards to its exposure to the dollar gold price is to remain unhedged. The Group may from time to time establish currency and/or interest rate and/or commodity financial instruments to protect underlying cash flows.

On the date a derivative contract is entered into, the Group designates the derivative as (1) a hedge of the fair value of a recognised asset or liability (fair value hedge), (2) a hedge of a forecast transaction or a firm commitment (cash flow hedge), (3) a hedge of a net investment in a foreign entity, or (4) should the derivative not fall into one of the three categories above it is not regarded as a hedge.

Derivative financial instruments are initially recognised in the statement of financial position at fair value and subsequently remeasured at their fair value, unless they meet the criteria for the normal purchases normal sales exemption.

Provided the Group’s derivative transactions do not qualify for hedge accounting, changes in the fair value of such derivatives are recognised immediately in profit or loss.

8.3 Embedded derivatives

The Group assesses whether an embedded derivative is required to be separated from a host contract and accounted for as a derivative when the Group first becomes a party to a contract.

Embedded derivatives are separated from the host contract and accounted for separately if:

• The economic characteristics and risks of the host contract and the embedded derivative are not closely related;

• A separate instrument with the same terms as the embedded derivative would meet the definition of a derivative; and

• The combined instrument is not measured at fair value through profit or loss.

Subsequent reassessment is not performed unless there is a change in the terms of the contract that significantly modifies the cash flows.

9. PROVISIONS

Provisions are recognised when the Group has a present legal or constructive obligation resulting from past events and it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation.

10. PROVISION FOR ENVIRONMENTAL REHABILITATION COSTS

Long-term provisions for environmental rehabilitation costs are based on the Group’s environmental management plans, in compliance with applicable environmental and regulatory requirements.

Rehabilitation work can include facility decommissioning and dismantling, removal or treatment of waste materials, site and land rehabilitation, including compliance with and monitoring of environmental regulations, security and other site-related costs required to perform the rehabilitation work and operations of equipment designed to reduce or eliminate environmental effects.

Full provision is made based on the net present value of the estimated cost of restoring the environmental disturbance that has occurred up to the reporting date. The unwinding of the obligation is accounted for in profit or loss.

The estimated costs of rehabilitation are reviewed annually and adjusted as appropriate for changes in legislation, technology or other circumstances. Cost estimates are not reduced by the potential proceeds from the sale of assets or from plant clean up at closure.

Changes in estimates are capitalised or reversed against the relevant asset, except where a reduction in the provision is greater than the remaining net book value of the related asset, in which case the value is reduced to nil and the remaining adjustment is recognised in profit or loss. In the case of closed sites, changes in estimates and assumptions are recognised in profit or loss. Estimates are discounted at the risk-free rate in the jurisdiction of the obligation.

Increases due to additional environmental disturbances are capitalised and amortised over the remaining lives of the mines. These increases are accounted for on a net present value basis.

For the South African and Ghanaian operations, annual contributions are made to a dedicated rehabilitation trust fund and dedicated bank account, respectively, to fund the estimated cost of rehabilitation during and at the end of the life-of-mine. The amounts contributed to this trust fund/bank account are included under non-current assets. Interest earned on monies paid to rehabilitation trust fund/bank account is accrued on a time proportion basis and is recorded as interest income.

In respect of the South African, Ghanaian and Peruvian operations, bank and other guarantees are provided for funding of the environmental rehabilitation obligations.

11. EMPLOYEE BENEFITS

11.1 Short-term employee benefits

Short-term employee benefits are expensed as the related service is provided. A liability is recognised for the amount expected to be paid if the Group has a present legal or constructive obligation to pay this amount as a result of past service provided by the employee and the obligation can be estimated reliably.

11.2 Pension and provident funds

The Group operates a defined contribution retirement plan and contributes to a number of industry-based defined contribution retirement plans. The retirement plans are funded by payments from employees and Group companies.

Contributions to defined contribution funds are recognised as an employee benefit expense in profit or loss in the periods during which related services are rendered by employees.

11.3 Share-based payments

The Group operates a number of equity-settled compensation plans. The fair value of the equity-settled instruments is measured by reference to the fair value of the equity instrument granted which in turn is determined using the Black-Scholes and Monte Carlo simulation models on the date of grant.

Fair value is based on market prices of the equity-settled instruments granted, if available, taking into account the terms and conditions upon which those equity-settled instruments were granted. Fair value of equity-settled instruments granted is estimated using appropriate valuation models and appropriate assumptions at grant date. Non-market vesting conditions (service period prior to vesting) are not taken into account when estimating the fair value of the equity-settled instruments at grant date. Market conditions are taken into account in determining the fair value at grant date.

The fair value of the equity-settled instruments is recognised as an employee benefit expense over the vesting period based on the Group’s estimate of the number of instruments that will eventually vest, with a corresponding increase in equity. Vesting assumptions for non-market conditions are reviewed at each reporting date to ensure they reflect current expectations.

Where the terms of an equity-settled award are modified, the originally determined expense is recognised as if the terms had not been modified. In addition, an expense is recognised for any modification, which increases the total fair value of the share-based payment arrangement, or is otherwise beneficial to the participant as measured at the date of the modification.

11.4 Long-term incentive plan

The Group operates a long-term incentive plan.

The Group’s net obligation in respect of the long-term incentive plan is the amount of future benefit that employees have earned in return for their services in the current and prior periods. That benefit is estimated using appropriate assumptions and is discounted to determine its present value at each reporting date. Re-measurements are recognised in profit or loss in the period in which they arise.

11.5 Termination benefits

Termination benefits are payable when employment is terminated by the Group before the normal retirement date, or whenever an employee accepts voluntary redundancy in exchange for these benefits. Termination benefits are expensed at the earlier of the date the Group can no longer withdraw the offer of those benefits or the date the Group recognises costs for a restructuring. Benefits falling due more than 12 months after the reporting date are discounted to present value.

12. SHARE CAPITAL

12.1 Ordinary share capital

Ordinary shares are classified as equity. Incremental costs directly attributable to the issue of ordinary shares are recognised as a deduction from equity, net of any tax effects.

12.2 Repurchase and reissue of share capital

When share capital recognised as equity is repurchased, the amount of the consideration paid, which includes directly attributable costs, net of any tax effects, is recognised as a deduction from equity. Repurchased shares are classified as treasury shares and are deducted from equity. When treasury shares are sold or reissued subsequently, the amount received is recognised as an increase in equity, and the resulting surplus or deficit on the transaction is presented in share premium.

13. REVENUE RECOGNITION

Revenue is recognised to the extent that it is probable that economic benefits will flow to the Group and the amount of revenue can be reliably measured. Revenue is stated at the fair value of the consideration received or receivable.

Revenue arising from gold, copper and silver sales is recognised when the significant risks and rewards of ownership pass to the buyer. The price of gold, copper and silver is determined by market forces.

Copper and gold concentrate revenue is calculated, net of refining and treatment charges, on a best estimate basis on shipment date, using forward metal prices to the estimated final pricing date, adjusted for the specific terms of the agreements. Variations between the price recorded at the shipment date and the actual final price received are caused by changes in prevailing copper and gold prices, and result in an embedded derivative in the trade receivable. The embedded derivative is marked-to-market each period until final settlement occurs, with changes in fair value classified as provisional price adjustments and included as a component of revenue.

14. INVESTMENT INCOME

Investment income comprises interest income on funds invested and dividend income from listed and unlisted investments.

Investment income is recognised to the extent that it is probable that economic benefits will flow to the Group and the amount of investment income can be reliably measured. Investment income is stated at the fair value of the consideration received or receivable.

14.1 Dividends, which include capitalisation dividends, are recognised when the right to receive payment is established.

14.2 Interest income is recognised on a time proportion basis taking account the principal outstanding and the effective rate over the period to maturity.

Cash flows from dividends and interest received are classified under operating activities in the statement of cash flows.

15. DIVIDENDS DECLARED

Dividends and the related taxation thereon are recognised only when such dividends are declared.

Dividends withholding tax is a tax on shareholders receiving dividends and is applicable to all dividends paid. The Group withholds dividends tax on behalf of its shareholders at a rate of 20% on dividends paid. Amounts withheld are not recognised as part of the Group’s tax charge but rather as part of the dividend paid recognised directly in equity.

Cash flows from dividends paid are classified under operating activities in the statement of cash flows.

16. EARNINGS PER SHARE

The Group presents basic and diluted earnings per share. Basic earnings per share is calculated based on the profit attributable to ordinary shareholders divided by the weighted average number of ordinary shares in issue during the period. Diluted earnings per share is determined by adjusting the profit attributable to ordinary shareholders, if applicable, and the weighted average number of ordinary shares in issue for ordinary shares that may be issued in the future.

17. NON-CURRENT ASSETS HELD FOR SALE

Non-current assets (or disposal groups) comprising assets and liabilities, are classified as held for sale if it is highly probable they will be recovered primarily through sale rather than through continuing use. These assets may be a component of an entity, a disposal group or an individual non-current asset.

Non-current assets held for sale are stated at the lower of carrying amount and fair value less costs to sell. Once classified as held for sale or distribution, property, plant and equipment is no longer amortised or depreciated.

18. DISCONTINUED OPERATIONS

A discontinued operation is a component of the Group’s business, the operations and cash flows of which can be clearly distinguished from the rest of the Group and which:

• Represents a separate major line of business or geographic area of operations;

• Is part of a single co-ordinated plan to dispose of a separate major line of business or geographic area of operations; or

• Is a subsidiary acquired exclusively with a view to re-sale.

Classification as a discontinued operation occurs at the earlier of disposal or when the operation meets the criteria to be classified as held-for-sale, if earlier.

When an operation is classified as a discontinued operation, the comparative income statement and statement of cash flows are re-presented as if the operation had been discontinued from the start of the comparative period.

19. SEGMENTAL REPORTING

Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker and is based on individual mining operations. The chief operating decision-maker, who is responsible for allocating resources and assessing performance of the operating segments, has been identified as the Executive Committee that makes strategic decisions.

20. HEADLINE EARNINGS

Headline earnings is an additional earnings number that is permitted by IAS 33 Earnings per Share (“IAS 33”) as set out in the SAICA Circular 2/2015 (Circular). The starting point is earnings as determined in IAS 33, excluding separately identifiable remeasurements net of related tax (both current and deferred) and related non-controlling interest, other than re-measurements specifically included in headline earnings. A remeasurement is an amount recognised in profit or loss relating to any change (whether realised or unrealised) in the carrying amount of an asset or liability that arose after the initial recognition of such asset or liability. Included remeasurement items are included in Section C of the Circular.

2 The methodology for amortisation and depreciation at Cerro Corona was amended in 2017, changing to gold ounces produced from tonnes mined. Gold ounces are considered a better reflection of the pattern in which the mine’s future economic benefits are expected to be consumed by the mine in line with the declining grade over the life-of-mine.

2 The impact of the change in useful life at Cerro Corona resulted in an increase in amortisation and depreciation of US$24.5 million for the 2017 year.

2 The methodology for amortisation of the mineral rights asset at the Australian operations was corrected during the year. Refer note 40 for further details.

2 The impact of the correction of the amortisation methodology at the Australian operations resulted in an increase in amortisation of US$5.7 million for the 2017 year.

2 Given the nature of the inputs used to calculate the amortisation and depreciation, namely future production as well as proven and probable reserves, it is not practicable to estimate the future impact the change in useful life and correction in methodology will have on amortisation and depreciation.

Share-Based Payments

5. SHARE-BASED PAYMENTS

The Group granted equity-settled instruments comprising share options and restricted shares to executive directors, certain officers and employees. During the year ended 31 December 2017, the following share plans were in place: The Gold Fields Limited 2005 Share Plan, the Gold Fields Limited 2012 Share Plan and the Gold Fields Limited 2012 Share Plan as amended in 2016. During 2016, the Gold Fields Limited 2012 Share Plan as amended in 2016 was introduced to replace the long-term incentive plan (“LTIP”). Allocations under this plan were made during 2016 and 2017.

(a) Gold Fields Limited 2005 Share Plan

At the Annual General Meeting on 17 November 2005, shareholders approved the adoption of the Gold Fields Limited 2005 Share Plan to replace the GF Management Incentive Scheme approved in 1999. The plan provided for two methods of participation, namely the Performance Allocated Share Appreciation Rights Method (“SARS”) and the Performance Vesting Restricted Share Method (“PVRS”). This plan sought to attract, retain, motivate and reward participating employees on a basis which sought to align the interests of such employees with those of the Company’s shareholders. No further allocations of options under this plan are being made following the introduction of the Gold Fields Limited 2012 Share Plan (see below) and the plan will be closed once all options have been exercised or forfeited.

The following table summarises the movement of share options under the Gold Fields Limited 2005 Share Plan during the years ended 31 December 2017, 2016 and 2015:

(b)(i) Gold Fields Limited 2012 Share Plan – awards prior to 1 March 2016

At the Annual General Meeting on 14 May 2012 shareholders approved the adoption of the Gold Fields Limited 2012 Share Plan to replace the Gold Fields Limited 2005 Share Plan. The plan provided for two methods of participation, namely the Performance Share Method (“PS”) and the Bonus Share Method (“BS”). This plan sought to attract, retain, motivate and reward participating employees on a basis which sought to align the interests of such employees with those of the Company’s shareholders. No further allocations of options under this plan are being made following the introduction of the Gold Fields Limited 2012 Share Plan amended – awards after 1 March 2016 (see below) and the plan was closed.

The salient features of the plan were:

• PS were offered to participants annually in March. Quarterly allocations of PS were also made in June, September and December on a pro rata basis to qualifying new employees. PS were performance-related shares, granted at zero cost (the shares are granted in exchange for the rendering of service by participants to the Group during the three-year restricted period prior to the share vesting period);

• Based on the rules of the plan, the actual number of PS which would be settled to a participant three years after the original award date was determined by the Group’s performance measured against the performance of seven other major gold mining companies (“the peer group”) based on the relative change in the Gold Fields share price compared to the basket of respective US Dollar share prices of the peer group. Furthermore, for PS awards to be settled to members of the Executive Committee, an internal Company performance target is required to be met before the external relative measure is applied. The internal target performance criterion has been set at 85% of the Group’s planned gold production over the three-year measurement period as set out in the business plans of the Group approved by the Board. In the event that the internal target performance criterion is met the full initial target award shall be settled on the settlement date. In addition, the Remuneration Committee has determined that the number of PS to be settled may be increased by up to 200% of the number of the initial target PS conditionally awarded, depending on the performance of the Company relative to the performance of the peer group, based on the relative change in the Gold Fields share price compared to the basket of respective US Dollar share prices of the peer group;

• The performance of the Company that resulted in the settlement of shares was measured by the Company’s share price performance relative to the share price performance of the following peer gold mining companies, collectively referred to as “the peer group”, over the three-year period:

- AngloGold Ashanti;

- Barrick Gold Corporation;

- Goldcorp Incorporated;

- Harmony Gold Mining Company;

- Newmont Mining Corporation;

- Newcrest Mining Limited; and

- Kinross Gold Corporation.

• The performance of the Company’s shares against the shares of the peer group was measured for the three-year period running from the relevant award date;

• BS were offered to participants annually in March; and

• Based on the rules of the plan, the actual number of BS which would be settled in equal proportions to a participant over a nine-month and a 18-month period after the original award date was determined by the employee’s annual cash bonus calculated with reference to actual performance against predetermined targets for the financial year ended immediately preceding the award date.

The following table summarises the movement of share options under the Gold Fields Limited 2012 Share Plan during the years ended 31 December 2017, 2016 and 2015:

(b)(ii) Gold Fields Limited 2012 Share Plan amended – awards after 1 March 2016

At the Annual General Meeting on 18 May 2016, shareholders approved the adoption of the revised Gold Fields Limited 2012 Share Plan to replace the LTIP. The plan provides for four types of participation, namely Performance Shares (“PS”), Retention Shares (“RS”), Restricted Shares (“RSS”) and Matching Shares (“MS”). This plan is in place to attract, retain, motivate and reward participating employees on a basis which seeks to align the interests of such employees with those of the Company’s shareholders. Allocations of options under this plan were made during 2016 and 2017. Currently, the last vesting date is 28 February 2020.

The salient features of the plan were:

• PS are offered to participants annually in March. PS are performance-related shares, granted at zero cost (the shares are granted in exchange for the rendering of service by participants to the Group during the three-year restricted period prior to the share vesting period);

• Based on the rules of the plan, the actual number of PS which will be settled to a participant three years after the original award date is determined by the following performance conditions:

Performance condition	Weighting		Threshold	Target	Stretch and cap
Absolute total shareholder return (“TSR”)		33%	N/A – No vesting below target	Compounded cost of equity in real terms over three-year performance period	Compounded cost of equity in real terms over three-year performance period +6% per annum
Relative TSR		33%	Median of the peer group	Linear vesting to apply between median and upper quartile performance and capped at upper quartile performance
Free cash flow margin (“FCFM”)		34%	Average FCFM over performance period of 5% at a gold price of $1,300/oz – margin to be adjusted relative to the actual gold price for the three-year period	Average FCFM over performance period of 15% at a gold price of $1,300/oz – margin to be adjusted relative to the actual gold price for the three-year period	Average FCFM over performance period of 20% at a gold price of $1,300/oz – margin to be adjusted relative to the actual gold price for the three-year period

The vesting profile will be as follows:

Performance condition	Threshold			Target			Stretch and cap
Absolute TSR1, 4		0	%		100	%		200	%
Relative TSR1, 3, 4		0	%		100	%		200	%
FCFM2		0	%		100	%		200	%

1 Absolute TSR and relative TSR: Linear vesting will occur between target and stretch (no vesting occurs for performance below target).

2 FCFM: Linear vesting will occur between threshold, target and stretch.

3 The peer group consists of 10 companies: AngloGold Ashanti, Goldcorp, Barrick, Eldorado Gold, Randgold, Yamana, Agnico Eagle, Kinross, Newmont and Newcrest.

4 TSR will be calculated as the compounded annual growth rate (“CAGR”) of the TSR index between the average of the 60 trading days up to the first day of the performance period and the average of the 60 trading days up to the last day of the performance period. TSR will be defined as the return on investing in ordinary shares in the Company at the start of the performance period, holding the shares and reinvesting the dividends received on the portfolio in Gold Fields shares over the performance period. The USD TSR index, provided by external service providers will be based on the US$ share price.

• RS can be awarded on an ad hoc basis to key employees where a retention risk has been identified. These will be subject to the vesting condition of service over a period of three years only;

• RSS: In 2016, Gold Fields implemented a Minimum Shareholding Requirement (“MSR”) where executives are required to build and to hold a percentage of their salary in Gold Fields shares over a period of five years. Executives will be given the opportunity (as at the approval date of the MSR), prior to the annual bonus being communicated or the upcoming vesting date of the LTIP award or PS, to elect to receive all or a portion of their annual bonus or cash LTIP in restricted shares or to convert all or a portion of their unvested PS into restricted shares towards fulfilment of the MSR. These shares are subject to the holding period as set out below.

This holding period will mean that the restricted shares may not be sold or disposed of and that the beneficial interest must be retained therein until the earlier of:

• Notice given by the executive, provided that such notice may only be given after five years from the start of the holding period;

• Termination of employment of that employee, i.e. retirement, retrenchment, ill health, death, resignation or dismissal;

• Abolishment of the MSR; or

• In special circumstances such as proven financial hardship or compliance with the MSR, upon application by the employee and approval by the Remuneration Committee.

MS: To facilitate the introduction of the MSR policy and to compensate executives for participating in RSS and holding their shares for an additional five years, thus exposing themselves to further market volatility, the Company intends to make a matching award. This is intended to entail a conditional award of shares of one share for every three shares committed towards the MSR (matching shares), rounded to the nearest full share. The matching shares will vest on a date that corresponds with the end of the holding period of the shares committed towards the MSR provided the executive is still in the employment of the Company and has met the MSR requirements of the MSR policy, including having sustainably accumulated shares to reach the MSR over the five-year holding period.

At 31 December 2017, the maximum number of matching shares that could vest, based on shares already committed to MSR, at the end of five years was 403,027 (2016: 169,158) shares.

The fair value of equity instruments granted during the year ended 31 December 2017 and 2016 were valued using the Monte Carlo simulation model:
Monte Carlo simulation
Performance shares
This model is used to value the performance shares. The inputs to the model for options granted during the year were as follows:
- weighted average historical volatility (based on a statistical analysis of the share price on a weighted moving average basis for the expected term of the option)		64.3	%		58.1	%
- expected term (years)		3 years			3 years
- dividend yield1		n/a			n/a
- weighted average three-year risk free interest rate (based on US interest rates)		1.6	%		0.5	%
- weighted average fair value (United States dollars)		4.2			2.6

1 There is no dividend yield applied to the Monte Carlo simulation model as the performance conditions follow a total shareholder return method.

1 Following the identification of impairment indicators at 30 June 2015, the investment in Hummingbird was valued at its recoverable amount, which resulted in an impairment of US$7.5 million. The recoverable amount was based on the investment’s fair value at the time, being its quoted market price (level 1 of the fair value hierarchy). The impairment is included in the “Corporate and other” segment.

2 Following the identification of impairment indicators at 31 December 2015, FSE was valued at its recoverable amount which resulted in an impairment of US$101.4 million. The recoverable amount was based on the fair value less cost of disposal (“FVLCOD”) of the investment (level 2 of the fair value hierarchy). FVLCOD was indirectly derived from the market value of Lepanto Consolidated Mining Company, being the 60% shareholder of FSE. The impairment is included in the “Corporate and other” segment.

3 Following the Group’s decision during 2013 to dispose of non-core projects, APP was classified as held for sale and, accordingly, valued at the lower of fair value less cost of disposal or carrying value which resulted in impairments of US$89.7 million and US$3.2 million during 2013 and 2014, respectively. APP’s carrying value at 31 December 2014 after the above impairments was US$40.0 million which was based on an offer received close to the 2014 year-end. During 2015, active marketing activities for the disposal of the project continued after the 2014 offer was not realised. During 2015, APP was further impaired by US$39.0 million, resulting in a carrying value of US$1.0 million at 31 December 2015. The impairment is included in the “Corporate and other” segment. At 31 December 2016, APP no longer met the definition of an asset held for sale and was reclassified to property, plant and equipment at a recoverable amount of US$1.0 million. During 2017, active marketing activities continued and as a result, a sale agreement was concluded comprising a purchase offer of US$40.0 million cash and a 2% net smelter refiner royalty on all metals. As a result, the impairment of US$39.0 million previously recorded, was reversed and APP was reclassified as an asset held for sale at 31 December 2017. Refer note 12 for further details.

4 Reversal of impairment and impairment of property, plant and equipment is made up as follows:

	UNITED STATES DOLLAR
	2017			2016			2015
– Redundant assets at Cerro Corona (2015: Cerro Corona)		(0.8	)		—			(6.7	)
– Reversal of cash-generating unit impairment at Cerro Corona (2016: impairment of $66.4 million)		53.4			(66.4	)		—
(The impairment in 2016 was due to the reduction in gold and copper reserves due to depletion, a decrease in the gold and copper price assumptions for 2017 and 2018, a lower resource price and an increase in the Peru tax rate. The reversal of the impairment in 2017 was due to a higher value-in-use following the completion of a pre-feasibility study in 2017, with the assistance of external specialists, extending the life-of-mine from 2023 to 2030 by optimising the tailings density and increasing the tailings capacity by using in-pit tailings after mining activities end. After taking into account one year amortisation, the reversal of impairment amounted to US$53.4 million (2016: The recoverable amount was based on its FVLCOD calculated using a combination of the market and the income approach (level 3 of the fair value hierarchy)). Refer to accounting policies on page 139 for assumptions).
– Damang assets held for sale		—			(7.6	)		—
(Following the Damang re-investment plan, a decision was taken to sell certain mining fleet assets and related spares. The sale of the assets is expected to be concluded during 2017. As a result, the assets were classified as held for sale (refer note 12) and valued at the lower of FVLCOD or carrying value which resulted in an impairment of US$7.6 million).
– Asset-specific impairment at Tarkwa		(6.8	)		—			—
(Relating to aged, high maintenance and low effectiveness mining fleet that is no longer used).
– Asset-specific impairment at Damang		(3.5	)		(2.4	)		(35.8	)
(Relating to all assets at the Rex pit. Following a series of optimisations, the extensional drilling, completed in 2017, failed to deliver sufficient tonnages at viable grades to warrant further work (2016: inoperable mining fleet that is no longer used under the current life-of-mine plan, 2015: Immovable mining assets written off to nil that would no longer be used under the current life-of-mine plan)).
Reversal of impairment and impairment of property, plant and equipment – other		42.3			(76.4)			(42.5)

5 At 31 December 2017, the Group recognised an impairment of R3,495.0 billion (US$277.8 million) at South Deep. The recoverable amount was based on its FVLCOD calculated using a combination of the market and the income approach (level 3 of the fair value hierarchy). The impairment calculation was based on the 2017 life-of-mine plan using the following assumptions:

- Gold price of R525,000 per kilogram;

- Resource price of US$17 per ounce at the Rand/Dollar exchange rate of R12.58;

- Resource ounces of 29.0 million ounces;

- Life-of-mine: 78 years; and

- Discount rate: 13.5% nominal.

The impairment is due to a reduction in the gold price assumptions, a lower resource price and a deferral of production.

2 The Mineral and Petroleum Resource Royalty Act 2008 (“Royalty Act”) was promulgated on 24 November 2008 and became effective from 1 March 2010. The Royalty Act imposes a royalty on refined (mineral resources that have undergone a comprehensive level of beneficiation such as smelting and refining as defined in Schedule 1 of the Act) and unrefined (mineral resources that have undergone limited beneficiation as defined in Schedule 2 of the Act) minerals payable to the state. The royalty in respect of refined minerals (which include gold refined to 99.5% and above and platinum) is calculated by dividing earnings before interest and taxes (“EBIT”) by the product of 12.5 times gross revenue calculated as a percentage, plus an additional 0.5%. EBIT refers to taxable mining income (with certain exceptions such as no deduction for interest payable and foreign exchange losses) before assessed losses but after capital expenditure. A maximum royalty of 5% has been introduced on refined minerals. The effective rate of royalty tax payable for the year ended 31 December 2017 was 0.5% of mining revenue (2016: 0.5% and 2015: 0.5%) equalling the minimum charge per the formula.

3 The Australian operations are subject to a 2.5% (2016: 2.5% and 2015: 2.5%) gold royalty on revenue as the mineral rights are owned by the state.

4 Minerals are owned by the Republic of Ghana and held in trust by the President. During 2016, Gold Fields signed a Development Agreement (“DA”) with the Government of Ghana for both the Tarkwa and Damang mines. This agreement stated that the Ghanaian operations will be subject to a sliding scale for royalty rates, linked to the prevailing gold price (effective 1 January 2017). The sliding scale is as follows:

Average gold price
Low value			High value		Royalty rate
	US$0.00	-		US$1,299.99		3.0	%
	US$1,300.00	-		US$1,499.99		3.5	%
	US$1,450.00	-		US$2,299.99		4.1	%
	US$2,300.00	-		Unlimited		5.0	%

During 2016 and 2015, the Ghanaian operations were subject to a 5.0% gold royalty on revenue.

5 The Peruvian operations are subject to a mining royalty calculated on a sliding scale with rates ranging from 1% to 12% of the value of operating profit.

3 The functional currency of Cerro Corona is US Dollar, however, the Peruvian tax base is based on values in Peruvian Nuevo Sol.

4 Deferred tax assets amounting to US$12.9 million (2016: US$34.9 million and 2015: US$112.5 million) were not recognised during the year at Cerro Corona and Damang to the extent that there is insufficient future taxable income available. At Cerro Corona, deferred tax assets amounting to US$12.9 million (2016: US$33.5 million and 2015: US$76.9 million) were not recognised during the year related to deductible temporary differences on additions to fixed assets in the current financial year that would only reverse after the end of the life-of-mine (“LoM”) of Cerro Corona. At Damang, deferred tax assets amounting to US$nil (2016: US$1.4 million and 2015: US$35.6 million) were not recognised during the year related to net deductible temporary differences reversing in the current financial year. In making this determination, the Group analysed, among others, forecasts of future earnings and the nature and timing of future deductions and benefits represented by deferred tax assets.

5 Due to year-end assessments, deferred tax assets amounting to US$17.3 million and US$2.5 million were recognised at Cerro Corona and Damang, respectively, to the extent that there is sufficient future taxable income available. During 2017, Cerro Corona completed a pre-feasibility study extending the life-of-mine (“LoM”) from 2023 to 2030. A significant portion of the deductible temporary differences on fixed assets that were scheduled to reverse after the end of the LoM at Cerro Corona will now reverse over the extended LoM, resulting in the recognition of deferred tax assets amounting to US$17.3 million. At Damang, the LoM indicated that the mine would make taxable profits in the future that would support the write back of a portion of the deferred tax asset amounting to US$2.5 million. In making this determination, the Group analysed, among others, forecasts of future earnings and the nature and timing of future deductions and benefits represented by deferred tax assets.

1 South African mining tax on mining income is determined according to a formula which takes into account the profit and revenue from mining operations. South African mining taxable income is determined after the deduction of all mining capital expenditure, with the proviso that this cannot result in an assessed loss. Capital expenditure amounts not deducted are carried forward as unredeemed capital expenditure to be deducted from future mining income. Accounting depreciation is ignored for the purpose of calculating South African mining taxation. The effective mining tax rate for Gold Fields Operations Limited (“GFO”) and GFI Joint Venture Holdings Proprietary Limited (“GFIJVH”), owners of the South Deep mine, has been calculated at 30% (2016: 30% and 2015: 30%).

In the formula above, Y is the percentage rate of tax payable and X is the ratio of mining profit, after the deduction of redeemable capital expenditure, to mining revenue expressed as a percentage.

2 Non-mining income of South African mining operations consists primarily of interest income.

3 On 11 March 2016, Gold Fields signed a development agreement with the Government of Ghana for both the Tarkwa and Damang mines. This agreement resulted in a reduction in the corporate tax rate from 35.0% to 32.5%, effective 17 March 2016.

Deferred tax is provided at the expected future rate for mining operations arising from temporary differences between the carrying values and tax values of assets and liabilities.

At 31 December 2017, the Group had the following estimated amounts available for set-off against future income (pre-tax):

	2017						2016

1 These deductions are available to be utilised against income generated by the relevant tax entity and do not expire unless the tax entity concerned ceases to operate for a period of longer than one year. Under South African mining tax ring-fencing legislation, each tax entity is treated separately and as such these deductions can only be utilised by the tax entities in which the deductions have been generated. South African tax losses and unredeemed capital expenditure have no expiration date.

2 The above R2,427.1 million (2016: R1,929.2 million) comprises US$925.5 million gross recognised capital allowance and US$1,501.6 million gross unrecognised capital allowance (2016: US$796.6 million gross recognised capital allowance and US$1,132.6 million gross unrecognised capital allowance).

3 During 2014, the South African Revenue Services (“SARS”) issued a Finalisation of Audit Letter (“the Audit Letter”) stating that SARS has disallowed US$182.2 million of GFIJVH’s gross recognised capital allowance of US$925.5 million. Refer note 34 on Contingent Liabilities for further details.

4 The total tax losses of US$445.9 million (2016: US$388.8 million) comprise US$22.9 million (2016: US$10.9 million) tax losses that expire between one and two years, US$57.6 million (2016: US$58.9 million) tax losses that expire between two and five years, US$30.4 million (2016: US$41.2 million) tax losses that expire between five and 10 years, US$43.2 million (2016: US$40.6 million) tax losses that expire after 10 years and US$291.8 million (2016: US$237.2 million) tax losses that have no expiry date.

5 The tax losses are available to be utilised against income generated by the relevant tax entity and do not expire.

6 Tax losses may be carried forward for five years. These losses expire on a first-in-first-out basis. Tax losses of US$44.5 million (2016: US$46.3 million) expire in two years, tax losses of US$19.0 million (2016: US$nil) expire in three years, tax losses of US$91.7 million (2016: US$19.4 million) expire in four years and tax losses of US$46.2 million (2016: US$3.0 million) expire in five years.

Discontinued Operations

12.1 DISCONTINUED OPERATIONS

Gold Fields disposed of its Darlot mine to ASX-listed Red 5 Limited (“Red 5”) for a total consideration of A$18.5 million, comprising A$12.0 million in cash and 130 million Red 5 shares. The cash component was made up of an upfront amount of A$7.0 million and A$5.0 million deferred for up to 24 months. The deferred consideration could be taken as additional shares in Red 5 or as cash at Gold Fields’ election.

Red 5 undertook a rights issue to assist with the funding of the cash component and for general working capital purposes. Gold Fields used the A$7.0 million to underwrite the rights issue. Gold Fields received a total number of 116,875,821 Red 5 shares under the underwriting agreement for a consideration of A$5.8 million.

All conditions precedent in terms of the sales agreement were met on 2 October 2017 and as a result Gold Fields accounted for a profit on the sale of Darlot of A$30.8 million (US$23.5 million). Post the completion of the sale, Gold Fields had a 19.9% shareholding in Red 5. Gold Fields does not have significant influence over Red 5 as the shareholding is below 20% and there are no qualitative factors indicating that significant influence exists.

The financial results of Darlot have been presented as a discontinued operation in the consolidated financial statements and comparative income statements and statements of cash flows have been restated as if Darlot had been discontinued from the start of the comparative period.

1 Following the Damang re-investment plan, a decision was taken during 2016 to sell certain mining fleet assets and related spares. As a result, the assets were classified as held for sale at 31 December 2016 and valued at the lower of FVLCOD or carrying value which resulted in an impairment of US$7.6 million. The sale of the assets concluded during 2017.

Mining fleet and related spares with carrying values of US$18.6 million and US$7.8 million, respectively, were reclassified to assets held for sale. Refer note 13 and 19 for further details.

2 At 31 December 2016, APP no longer met the definition of an asset held for sale and was reclassified to property, plant and equipment at a recoverable amount of US$1.0 million. During 2017, active marketing activities continued and as a result, a sale agreement was concluded comprising a purchase offer of US$40.0 million cash and a 2% net smelter refiner royalty on all metals. As a result, the impairment previously recorded, was reversed up to the value of the selling price and APP was reclassified as an asset held for sale at 31 December 2017. Refer note 6 for further details.

APP is included as part of corporate and other in the segment note. Refer note 41 for further details.

1 Included in the cost of mine development, infrastructure and other assets are exploration and evaluation assets amounting to US$10.8 million (2016: US$9.1 million).

2 Based on conversion of resources to reserves a portion of the cost of the mineral rights asset at the Australian operations is allocated from the non-depreciable component of the mineral rights asset to a depreciable component, at this point the mineral rights asset is reclassified from land, mineral rights and rehabilitation assets to mine development, infrastructure and other assets on a mine-by-mine basis. This reclassification relates to the transfer from the non-depreciable to the depreciable component for all periods from acquisition of the mineral rights to the year ended 31 December 2015 given the correction in methodology of the mineral rights asset. On an annual basis transfers are reflected as reclassifications.

3 Refer note 40 for further details.

4 The additions of US$275.9 million (A$372.4 million) are made up of US$197.1 million (A$266.0 million) cash additions and US$78.8 million (A$106.4 million) non-cash additions. Refer note 15.2 for further details.

5 Borrowing costs of US$22.9 million (2016: US$15.1 million) arising on Group general borrowings were capitalised during the period and comprised US$19.4 million (US$15.1 million) borrowing costs related to the qualifying projects at South Deep, US$2.1 million (2016: US$nil) borrowing costs related to the Damang reinvestment project and US$1.4 million (2016: US$nil) borrowing costs related to the Gruyere project. An average interest capitalisation rate of 5.3% (2016: 4.7%) was applied.

6 The impairment reversal of US$81.3 million (2016: charge of US$76.4 million) is made up of US$11.1 million (2016: US$76.4 million) impairment of property, plant and equipment, offset by the reversal of APP impairment amounting to US$39.0 million (refer note 6 for details) and the reversal of the Cerro Corona cash-generating unit impairment of US$53.4 million (refer note 6 for further details).

7 The write-off of exploration and evaluation assets is due to specific exploration programmes not yielding results to warrant further exploration at the Group’s Australian operations and the US$51.5 million (2016: US$41.4 million) for continuing operations is included in the US$109.8 million (2016: US$86.1 million) “Exploration expense” in the consolidated income statement.

8 Fleet assets and carbon-in-leach (“CIL”) plant in Ghana amounting to US$183.6 million (2016: US$95.5 million) have been pledged as security for the US$100 million senior secured revolving credit facility (refer note 24).

Translation adjustment		36.6			22.5
Balance at end of the year		76.6			317.8
The goodwill arose on the acquisition of South Deep and was attributable to the upside potential of the asset, synergies, deferred tax and the gold multiple.
The total goodwill is allocated to South Deep, the cash-generating unit (“CGU”), where it is tested for impairment. At 31 December 2017, the Group recognised an impairment of R3,495.0 million (US$277.8 million) at South Deep. Refer note 6 for further details.
In line with the accounting policy, the recoverable amount was determined with reference to “fair value less costs of disposal” (“FVLCOD”). Management’s estimates and assumptions used in the 31 December 2017 FVLCOD calculation include:
•   Long-term gold price of R525,000 per kilogram (US$1,300 per ounce) for the life-of-mine of 78 years (2016: R600,000 per kilogram (US$1,300 per ounce) for the life-of-mine of 79 years);
•   A nominal discount rate of 13.5% (2016: 13.5%);
•   Fair value of US$17 per resource ounce (2016: US$60.0 per resource ounce), used for resource with infrastructure to calculate the expected cash flows associated with value beyond proved and probable reserves;
•   Resource ounce of 29.0 million (2016: 26.0 million) ounces; and
•   The annual life-of-mine plan takes into account the following:
•   proved and probable ore reserves of South Deep;
•   cash flows are based on the life-of-mine plan which exceeds a period of five years; and
•   capital expenditure estimates over the life-of-mine plan.

Following the impairment loss recognised, the recoverable amount was equal to the carrying value of the South Deep CGU. Therefore, any adverse movement in a key assumption would lead to a further impairment.

Refer accounting policies on pages 138 to 139 for further discussion on the significant judgements and estimates associated with assessing the carrying value of property, plant and equipment and goodwill.

	Gold Fields paid US$10.0 million in option fees to Lepanto Consolidated Mining Company (“Lepanto”) during the six months ended 31 December 2010. In addition, Gold Fields paid non-refundable down payments of US$66.0 million during the year ended 31 December 2011 and US$44.0 million during the six months ended 31 December 2010 to Liberty Express Assets in accordance with the agreement concluded whereby the Group has the option to acquire 60% of FSE. On 31 March 2012, Gold Fields acquired 40% of the issued share capital and voting rights of FSE by contributing an additional non-refundable down payment of US$110.0 million. Lepanto owns the remaining 60% shareholding in FSE.
	The remaining 20% option is not likely to be exercised until such time as FSE obtains a Foreign Technical Assistance Agreement (“FTAA”) which allows for direct majority foreign ownership and control.
	FSE has a 31 December year-end and has been equity accounted since 1 April 2012. FSE’s equity accounting is based on results to 31 December 2017.

1 Refer note 6 for details of impairment.

2 Gold Fields’ share of loss after taxation represents exploration and other costs, including work completed on a scoping study, which is fully funded by Gold Fields as part of their equity contribution.

3 FSE is a company incorporated under the laws of the Philippines and owns the gold-copper Far Southeast exploration project (the “FSE project”). During the exploration phase of the FSE project and as long as the 20% option remains exercisable, the Group has joint control over the FSE project. The Group will only have the power to direct the activities of FSE once it exercises the option to acquire the additional 20% shareholding in FSE, which is only exercisable once an FTAA is obtained. FSE has no revenues or significant assets or liabilities. Assets included in FSE represent the rights to explore and eventually mine the FSE project.

Gold Fields’ interest in Maverix, listed on the Toronto Stock Exchange, was 28% (2016: 32%) at 31 December 2017.
On 23 December 2016, Gold Fields sold a portfolio of 11 producing and non-producing royalties to Maverix in exchange for 42.85 million common shares and 10.0 million common share purchase warrants of Maverix, realising a profit on disposal of US$48.0 million. The warrants are classified as derivative instruments and are included in investments (refer note 17).
Maverix has a 31 December year-end and has been equity-accounted since 23 December 2016. Equity accounting for Maverix is based on the latest available published results to 30 September 2017.

¹  During 2016, the Group’s holding was diluted from 21.6% to 8.8% following the issue of new shares by Bezant. In line with the Group’s accounting policy, this resulted in Bezant no longer being accounted for as an equity-accounted investee and was re-classified to available-for-sale financial investments.

²  Represents a holding of 25.7% in Rusoro.

The carrying value of Rusoro was written down to US$nil at 31 December 2010 due to losses incurred by the entity. The fair value, based on the quoted market price of the investment was US$7.7 million and US$23.9 million at 31 December 2017 and 31 December 2016, respectively. The unrecognised share of loss of Rusoro for the year amounted to US$2.0 million (2016: unrecognised shares of profits of US$18.7 million and 2015: unrecognised share of loss of US$3.6 million). The cumulative unrecognised share of losses of Rusoro amounted to US$196.0 million (2016: US$194.0 million).

On 22 August 2016, the Arbitration Tribunal, operating under the Additional Facility Rules of the World Bank’s International Centre for the Settlement of Investment Disputes, awarded Rusoro damages of US$967.8 million plus pre and post-award interest which currently equates to in excess of US$1.2 billion in the arbitration brought by Rusoro against the Bolivarian Republic of Venezuela (“Venezuela”).

Venezuela has not complied with the arbitration award terms, which were issued on 22 August 2016. On 6 December 2017, Rusoro obtained a judgement against Venezuela in the Superior Court of Justice in Ontario, Canada, in excess of US$1.3 billion. The judgement, which was issued on default as a result of Venezuela’s failure to appear before the Ontario court, arose out of Rusoro’s ongoing dispute with Venezuela over the South American nation’s seizure of its gold mining properties in the country. The Canadian judgement, which confirmed an arbitration award issued in Rusoro’s favour in the same amount, was issued on 25 April 2017. Venezuela did not appeal or seek to vacate the judgement, and its time to do so expired.

Rusoro further filed a suit in the Supreme Court of the State of New York, seeking recognition of the Canadian judgement. Rusoro brought the New York lawsuit in addition to an action it filed in the US District Court for the District of Columbia, which seeks recognition of and the entry of judgement on the original arbitration award. A favourable ruling from either the New York or DC court will entitle Rusoro to use all legal procedures - including broad discovery from both Venezuela and third parties - that US law provides judgement creditors. Any judgement issued in New York will also accrue interest at 9% per annum until the judgement is fully paid.

Management has not recognised this amount due to the uncertainty over its recoverability.

15.2 INTEREST IN JOINT OPERATION

On 13 December 2016, Gold Fields purchased 50% of the Gruyere Gold Project and entered into a 50:50 unincorporated joint operation with Gold Road Resources Limited (“Gold Road”) for the development and operation of the Gruyere Gold Project in Western Australia, which comprises the Gruyere gold deposit as well as additional resources including Central Bore and Attila/Alaric.

Gold Fields acquired 50% interest in the Gruyere Gold Project for a total purchase consideration of A$350.0 million payable in cash and a 1.5% royalty on Gold Fields’ share of production after total mine production exceeds 2 million ounces. The cash consideration is split with A$250.0 million payable on the effective date and A$100.0 million payable according to an agreed construction cash call schedule. Transaction costs of A$18.5 million (US$13.3 million) were incurred.

Share Capital

22. SHARE CAPITAL

Authorised and issued

As approved by shareholders at the Annual General Meeting (“AGM”) on 24 May 2017, the 1,000,000,000 authorised shares of the Company at the time having a par value of 50 cents each were converted into 1,000,000,000 ordinary no par value shares. Furthermore, subsequent to the conversion to no par value shares, in terms of s36(2)(a) of the South African Companies Act, the 1,000,000,000 ordinary no par value shares were increased to 2,000,000,000 ordinary no par value shares.

The issued share capital of the Company at 31 December 2017 is 820,614,217 (2016: 820,606,945) ordinary no par value shares.

During 2016, Gold Fields successfully completed a US$151.5 million (R2.3 billion) accelerated equity raising by way of a private placement to institutional investors.

A total number of 38,857,913 new Gold Fields shares were placed at a price of R59.50 per share which represented a 6.0% discount to the 30-day volume weighted average traded price, for the period ended 17 March 2016 and a 0.7% discount to the 50-day moving average.

In terms of the general authority granted by shareholders at the AGM on 24 May 2017, the authorised but unissued ordinary share capital of the Company representing not more than 5% of the issued share capital of the Company from time to time at that date, after setting aside so many ordinary shares as may be required to be allotted and issued pursuant to the share incentive schemes, was placed under the control of the directors. This authority expires at the next Annual General Meeting where shareholders will be asked to place under the control of the directors the authorised but unissued ordinary share capital of the Company representing not more than 5% of the issued share capital of the Company from time to time.

In terms of the JSE Listing Requirements, shareholders may, subject to certain conditions, authorise the directors to issue the shares held under their control for cash, other than by means of a rights offer, to shareholders. In order that the directors of the Company may be placed in a position to take advantage of favourable circumstances which may arise for the issue of such shares for cash, without restriction, for the benefit of the Company, shareholders will be asked to consider a special ordinary resolution to this effect at the forthcoming AGM.

Repurchase of shares

The Company has not exercised the general authority granted to buy back shares from its issued ordinary share capital granted at the AGM held on 24 May 2017. Currently, the number of ordinary shares that may be bought back in any one financial year may not exceed 20% of the issued ordinary share capital as of 24 May 2017. At the next AGM, shareholders will be asked to renew the general authority for the acquisition by the Company, or a subsidiary of the Company, of its own shares.

Beneficial shareholders

The following beneficial shareholders hold 5% or more of the Company’s listed ordinary shares:

Beneficial shareholder	Number of shares		% of issued ordinary shares

1 The balance is net of unamortised transaction costs amounting to US$4.5 million (2016: US$6.0 million) which will unwind over the remaining period of the notes as an interest expense.

The payment of all amounts due in respect of the Notes is unconditionally and irrevocably guaranteed by Gold Fields Limited (“Gold Fields”), Sibanye-Stillwater (up to 24 April 2015), Gold Fields Operations Limited (“GFO”) and Gold Fields Holdings Company (BVI) Limited (“GF Holdings”) (collectively “the Guarantors”), on a joint and several basis.

The notes and guarantees constitute direct, unsubordinated and unsecured obligations of Orogen and the Guarantors, respectively, and rank equally in right of payment among themselves and with all other existing and future unsubordinated and unsecured obligations of Orogen and the Guarantors, respectively.

Gold Fields Australasia Proprietary Limited (“GFA”) offered and accepted the purchase of an aggregate principal amount of notes equal to US$147.6 million at the purchase price of US$880 per US$1,000 in principal amount of notes. GFA intends to hold the notes acquired until their maturity on 7 October 2020. The purchase of the notes amounting to US$147.6 million was financed by drawing down under the US$1,510 million term loan and revolving credit facilities. The Group recognised a profit of US$17.7 million on the buy back of the notes.

2 Borrowings under the revolving senior secured credit facility are secured by first-ranking assignments of all rights, title and interest in all of La Cima’s concentrate sale agreements. In addition, the offshore and onshore collection accounts of La Cima are subject to an account control agreement and a first-ranking charge in favour of the lenders. This facility is non-recourse to the rest of the Group. The old revolving senior secured credit facility matured in 2017 and was refinanced through the new revolving credit facility on 22 September 2017.

3 Borrowings under the facility are guaranteed by Gold Fields Ghana Limited and Abosso Goldfields Limited. Borrowings under this facility are also secured by the registration of security over certain fleet vehicles owned by GF Ghana and Abosso (“Secured Assets”). In addition, the lenders are noted as first loss payees under the insurance contracts in respect of the Secured Assets and are assigned the rights under the maintenance contracts between certain suppliers of the Secured Assets. This facility is non-recourse to the rest of the Group. The US$70 million revolving senior secured credit facility matured in 2017 and was refinanced through the US$100 million revolving senior secured credit facility on 21 July 2017.

Fleet assets and CIL plant in Ghana amounting to US$183.6 million (2016: US$95.5 million) have been pledged as security for this facility.

4 Borrowings under this facility are guaranteed by Gold Fields, GF Holdings, Orogen, GFO, GFIJVH and Gold Fields Ghana Holdings (BVI) Limited (“GF Ghana”).

5 Borrowings under these facilities were guaranteed by Gold Fields, GF Holdings, Orogen, GFO and GFIJVH.

These facilities were cancelled and refinanced through the US$1,290 million term loan and revolving credit facilities on 6 June 2016, resulting in the total amount available to be US$nil at 31 December 2016.

6 Borrowings under this facility are guaranteed by Gold Fields, GF Holdings, Orogen, GFO, GFIJVH and Gold Fields Ghana Holdings (BVI) Limited (“GF Ghana”).

7 Borrowings under this facility are guaranteed by Gold Fields, GFO, GF Holdings, Orogen and GFIJVH

2 South African, Ghanaian, Australian and Peruvian mining companies are required by law to undertake rehabilitation as part of their ongoing operations. These environmental rehabilitation costs are funded as follows:

- Ghana - reclamation bonds underwritten by banks and restricted cash (refer note 18);

- South Africa - contributions into environmental trust funds (refer note 18) and guarantees;

- Australia - mine rehabilitation fund levy; and

- Peru - bank guarantees.

Refer to note 37 for expected timing of cash outflows in respect of the gross closure cost estimates. Certain current rehabilitation costs are charged to this provision as and when incurred.

During the six-month period ended 31 December 2010, a wholly owned subsidiary company of Gold Fields, Newshelf 899 Proprietary Limited, was created to acquire 100% of the South Deep net assets from Sibanye Gold. Sibanye Gold was a wholly owned subsidiary of Gold Fields at the time. The new company then issued 10 million Class B ordinary shares representing 10% of South Deep’s net worth to a consortium of BEE partners. Class B ordinary shareholders are entitled to a dividend of R2 per share and can convert the Class B to Class A ordinary shares over a 20-year period from the effective date of the transaction, 6 December 2010. The Class B ordinary shares will convert one-third after 10 years and a third thereafter on each fifth year anniversary.

This transaction was made up of a preferred BEE dividend (R151.4 million) and an equity component (R673.4 million). The preferred dividend represents a liability of Gold Fields to the Class B ordinary shareholders and was valued at R151.4 million, of which R20.0 million or US$1.5 million was declared on 23 March 2017 (16 March 2016: R20.0 million or US$1.3 million) and R20.0 million or US$1.6 million (2016: R20.0 million or US$1.4 million) is classified as a short-term portion under trade and other payables.

1 The principal health risks associated with Gold Fields’ mining operations in South Africa arise from occupational exposure to silica dust, noise, heat and certain hazardous chemicals. The most significant occupational diseases affecting Gold Fields’ workforce include lung diseases (such as silicosis, tuberculosis, a combination of the two and chronic obstructive airways disease (“COAD”) as well as noise-induced hearing loss (“NIHL”)).

A consolidated application was brought against several South African mining companies, including Gold Fields, for certification of a class action on behalf of current or former mineworkers (and their dependants) who have allegedly contracted silicosis and/or tuberculosis while working for one or more of the mining companies listed in the application.

The Occupational Lung Disease Working Group was formed in fiscal 2014 to address issues relating to compensation and medical care for occupational lung disease in the South African gold mining industry.

The Working Group, made up of African Rainbow Minerals, Anglo American SA, AngloGold Ashanti, Gold Fields, Harmony and Sibanye-Stillwater, has had extensive engagements with a wide range of stakeholders since its formation, including government, organised labour, other mining companies and the legal representatives of claimants who have filed legal actions against the companies.

The members of the Working Group are among respondent companies in a number of legal proceedings related to occupational lung disease, including the class action referred to above. The Working Group is, however, of the view that achieving a comprehensive settlement which is fair to both past, present and future employees and sustainable for the sector, is preferable to protracted litigation.

This matter was previously disclosed as a contingent liability as the amount could not be estimated reliably. As a result of the ongoing work of the Working Group and engagements with affected stakeholders since 31 December 2016, it has now become possible for Gold Fields to reliably estimate its share in the estimated cost in relation to the Working Group of a possible settlement of the class action claims and related costs. As a result, Gold Fields has provided an amount of US$31.9 million (R401.6 million) for this obligation in the statement of financial position at 31 December 2017. The nominal amount of this provision is US$40.5 million (R509.0 million)

The assumptions that were made in the determination of the provision include silicosis prevalence rates, estimated settlement per claimant, benefit take-up rates and disease progression rates. A discount rate of 8.24% was used, based on government bonds with similar terms to the anticipated settlements.

The ultimate outcome of these matters remains uncertain, with a possible failure to reach a settlement or to obtain the requisite court approval for a potential settlement. The provision is consequently subject to adjustment in the future, depending on the progress of the Working Group discussions, stakeholder engagements and the ongoing legal proceedings (refer note 34 for further details).

On 1 March 2014, the Remuneration Committee approved the Gold Fields Limited Long-Term Incentive Plan (“LTIP”). The plan provides for executive directors, certain officers and employees to receive a cash award conditional on the achievement of specified performance conditions relating to total shareholder return and free cash flow margin. The conditions are assessed over the performance cycle which runs over three calendar years. The expected timing of the cash outflows in respect of each grant is at the end of three years after the original award was made. The fair value of the free cash flow portion of the awards are valued based on the actual and expected achievement of the cash flow targets set out in the plan. No allocations were made under the LTIP in 2016 following the introduction of the Gold Fields Limited 2012 share plan as amended (refer note 5 for further details).

34. CONTINGENT LIABILITIES

Randgold and Exploration summons

On 21 August 2008, Gold Fields Operations Limited, or GFO, formerly known as Western Areas Limited, a subsidiary of Gold Fields, received a summons from Randgold and Exploration Company Limited, or R&E, and African Strategic Investment (Holdings) Limited. The summons claims that during the period that GFO was under the control of Brett Kebble, Roger Kebble and others, GFO assisted in the unlawful disposal of shares owned by R&E in Randgold Resources Limited, or Resources, and Afrikander Lease Limited, now Uranium One.

The claims have been computed in various ways. The highest claims have been computed on the basis of the highest prices of Resources and Uranium One between the dates of the alleged thefts and May 2017 (approximately R43.7 billion). The alternative claims will be computed based on the value of the shares as at the date of judgement (which is not yet calculable), plus dividend amounts that would have been received and based on the market value of the shares at the time they were allegedly misappropriated, plus dividends that would have been received (cumulatively equating to approximately R26.9 billion).

Simultaneously with delivering its plea, GFO joined certain third parties to the action (namely JCI Limited, JC Lamprecht, RAR Kebble and the deceased and insolvent estate of BK Kebble), in order to enable it to claim compensation against such third parties in the event that the plaintiffs are successful in one or more of their claims. In addition, notices in terms of section 2(2)(b) of the Apportionment of Damages Act, 1956 were served on various parties by GFO, in order to enable it to make a claim for a contribution against such parties in terms of the Apportionment of Damages Act, should the plaintiffs be successful in one or more of its claims.

A case manager has been appointed to manage the process to ensure that it progresses and that a trial date is allocated in due course.

GFO’s assessment remains that it has sustainable defences to these claims and, accordingly, GFO’s attorneys were instructed to vigorously defend the claims.

The ultimate outcome of the claims cannot presently be determined and, accordingly, no adjustment for any effects on the Company that may result from these claims, if any, has been made in the consolidated financial statements.

Silicosis

Class action

A consolidated application has been brought against several South African mining companies, including Gold Fields, for certification of a class action on behalf of current or former mineworkers (and their dependants) who have allegedly contracted silicosis and/or tuberculosis while working for one or more of the mining companies listed in the application.

In May 2016, the South African South Gauteng High Court ordered, among other things, the certification of a silicosis class and a tuberculosis class.

The High Court ruling did not represent a ruling on the merits of the cases brought against the mining companies. The Supreme Court of Appeal granted the mining companies leave to appeal against all aspects of the May 2016 judgement. The appeal hearing before the Supreme Court of Appeal was scheduled to be heard in March 2018.

On 10 January 2018, it was announced that attorneys representing all appellants and all respondents involved in the above appeal hearing before the Supreme Court of Appeal have written to the Registrar of the Supreme Court of Appeal asking that the appeal proceedings be postponed until further notice. The Supreme Court of Appeal has granted approval for the postponement. The joint letter written to the Registrar of the Supreme Court of Appeal explained that good faith settlement negotiations between the Occupational Lung Disease Working Group (see below) and claimants’ legal representatives have reached an advanced stage. In view of that, all parties consider it to be in the best interests of judicial economy and the efficient administration of justice that the matter be postponed.

Individual action

In addition to the class action above, an individual silicosis-related action has been instituted against Gold Fields and another mining company. In February 2018, the defendants (including Gold Fields) and the plaintiff entered into a confidential settlement agreement in full and final settlement of this matter.

Occupational Lung Disease Working Group

The Occupational Lung Disease Working Group was formed in fiscal 2014 to address issues relating to compensation and medical care for occupational lung disease in the South African gold mining industry.

The Working Group, made up of African Rainbow Minerals, Anglo American SA, AngloGold Ashanti, Gold Fields, Harmony and Sibanye-Stillwater, has had extensive engagements with a wide range of stakeholders since its formation, including government, organised labour, other mining companies and the legal representatives of claimants who have filed legal actions against the companies.

The members of the Working Group are among respondent companies in a number of legal proceedings related to occupational lung disease, including the class action referred to above. The Working Group is however of the view that achieving a comprehensive settlement which is both fair to past, present and future employees and sustainable for the sector, is preferable to protracted litigation.

The Working Group will continue with its efforts to find common ground with all stakeholders, including government, labour and the claimants’ legal representatives.

Financial provision

As at 30 June 2017, as a result of the ongoing work of the Working Group and engagements with affected stakeholders since 31 December 2016, Gold Fields provided an amount of US$30.2 million in the statement of financial position for its share of the estimated cost in relation to the Working Group of a possible settlement of the class action claims and related costs. The nominal value of this provision was US$40.5 million.

Gold Fields believes that this remains a reasonable estimate of its share of the estimated cost in relation to the Working Group of a possible settlement of the class action claims and related costs. The provision at 31 December 2017 of US$31.9 million increased due to the effect of unwinding and translation. The nominal value of this provision remains unchanged at US$40.5 million.

The ultimate outcome of these matters remains uncertain, with a possible failure to reach a settlement or to obtain the requisite court approval for a potential settlement. The provision is consequently subject to adjustment in the future, depending on the progress of the Working Group discussions, stakeholder engagements and the ongoing legal proceedings.

Acid mine drainage

Acid mine drainage (“AMD”) or acid rock drainage (“ARD”), collectively called acid drainage (“AD”) is formed when certain sulphide minerals in rocks are exposed to oxidising conditions (such as the presence of oxygen, combined with water). AD can occur under natural conditions or as a result of the sulphide minerals that are encountered and exposed to oxidation during mining or during storage in waste rock dumps, ore stockpiles or tailings dams. The acidic water that forms usually contains iron and other metals if they are contained in the host rock.

Gold Fields has identified incidences of AD, and the risk of potential short-term and long-term AD issues, specifically at its Cerro Corona, South Deep and Damang mines and, at currently immaterial levels, its Tarkwa and St Ives mines. The AD issues at Damang mine are confined to the rex open pit.

Gold Fields commissioned additional technical studies during 2015 to identify the steps required to prevent or mitigate the potentially material AD impacts at its Cerro Corona, Damang and South Deep operations, but none of these studies have allowed Gold Fields to generate a reliable estimate of the total potential impact on the Group. Gold Fields’ mine closure cost estimates for 2017 contain costs for the aspects of AD management which the Group has reliably been able to estimate.

Gold Fields continues to investigate technical solutions at its South Deep, Cerro Corona and Damang mines to better inform appropriate short- and long-term mitigation strategies for AD management and to work towards a reasonable cost estimate of these potential issues. Further studies are planned for 2018.

No adjustment for any effects on the Group that may result from AD, if any, has been made in the consolidated financial statements other than through the Group’s normal environmental rehabilitation costs provision (refer note 25.1).

Native Claim

On 14 October 2016, the High Court denied a request which affirmed that while St. Ives’ rights as tenement holder and the Ngadju people’s native title rights shall coexist, St. Ives’ rights shall prevail should there be any inconsistencies. This decision left no other opportunity for review or appeal and therefore, the matter is now considered closed in respect of Gold Fields.

South Deep tax dispute

The South Deep mine (“South Deep”) is jointly owned and operated by GFIJVH (50%) and GFO (50%).

At 31 December 2017, South Deep’s gross deductible temporary differences amounted to US$1,834.4 million (R23,076.4 million), resulting in a deferred tax asset balance of US$550.4 million (R6,923.0 million) in addition to other taxable temporary differences. This amount is included in the consolidated deferred tax asset of US$72.0 million on Gold Fields’ statement of financial position. South Deep’s gross deductible temporary differences comprises unredeemed capital expenditure balances of US$743.3 million (R9,350.3 million) (tax effect: US$223.0 million (R2,805.1 million)) at GFIJVH and US$716.4 million (R9,011.9 million) (tax effect: US$214.9 million (R2,703.6 million)) at GFO, a capital allowance balance (additional capital allowance) of US$182.2 million (R2,292.0 million) (tax effect: US$54.7 million (R687.6 million)) at GFIJVH and an assessed loss balance of US$192.5 million (R2,422.2 million) (tax effect: US$57.8 million (R726.7 million)) at GFO.

During the September 2014 quarter, the South African Revenue Services (“SARS”) issued a Finalisation of Audit Letter (“the Audit Letter”) stating that SARS has restated GFIJVH’s Additional Capital Allowance balance reflected on its 2011 tax return from US$182.2 million (R2,292.0 million) to nil. The tax effect of this amount is US$54.7 million (R687.6 million), that being referred to above as the “Additional Capital Allowance”.

The Additional Capital Allowance was claimed by GFIJVH in terms of section 36(11)(c) of the South African Income Tax Act, 1962 (the Act). The Additional Capital Allowance provides an incentive for new mining development and only applies to unredeemed capital expenditure. The Additional Capital Allowance allows a 12% capital allowance over and above actual capital expenditure incurred on developing “a deep level gold mine, as well as a further annual 12% allowance on the mine’s unredeemed capital expenditure balance brought forward, until the year that the mine starts earning mining taxable income (i.e. when all tax losses and unredeemed capital expenditure have been fully utilised).

In order to qualify for the Additional Capital Allowance, South Deep must qualify as a “post-1990 gold mine” as defined in the Act. A “post-1990 gold mine”, according to the Act, is defined as a gold mine which, in the opinion of the Director-General: Mineral and Energy Affairs, is an independent workable proposition and in respect of which a mining authorisation for gold mining was issued for the first time after 14 March 1990”.

During 1999, the Director-General: Minerals and Energy Affairs (“DME”) and SARS confirmed, in writing, that GFIJVH is a “post-1990 gold mine” as defined, and therefore qualified for the Additional Capital Allowance. Relying on these representations, GFIJVH subsequently filed its tax returns on this basis, as was confirmed by the DME and SARS.

In the Audit Letter, SARS stated that both the DME and SARS erred in issuing the confirmations as mentioned above and that GFIJVH does not qualify as a “post-1990 gold mine” and therefore does not qualify for the Additional Capital Allowance.

The Group has taken legal advice on the matter and was advised by external Senior Counsel that SARS should not be allowed to disallow the claiming of the additional capital allowance. GFIJVH has in the meantime not only formally appealed against the position taken by SARS, but also filed an application in the High Court and will vigorously defend its position. No resolution was achieved during the year as the Tax Court allowed SARS to amend its grounds of assessment in the days leading up to the commencement of the trial. Consequently the Tax Court proceedings could not be completed in the time allotted for the hearing. The continuance of the Tax Court hearing is expected to take place during 2019.

The Group is currently reviewing all its legal remedies, which include approaching the High Court for a declaratory order.

Accordingly, no adjustment for any effects on the Group that may result from the proceedings, if any, has been made in the consolidated financial statements.

The following methods and assumptions were used to estimate the fair value of each class of financial instrument:

Trade and other receivables, trade and other payables and cash and cash equivalents

The carrying amounts approximate fair values due to the short maturity of these instruments.

Investments

The fair value of publicly traded instruments (listed investments) is based on quoted market values. Unlisted investments are accounted for at cost with adjustments for write-downs where appropriate and the fair value approximates their carrying value. Derivative instruments are accounted for at fair value with adjustments to the fair value being recognised in profit or loss.

Environmental trust fund

The environmental trust fund is stated at fair value based on the nature of the fund’s investments.

Borrowings and current portion of borrowings

The fair value of borrowings and current portion of borrowings, except for the US$1 billion notes issued at a fixed interest rate, approximates their carrying amount as the impact of credit risk is included in the measurement of carrying amounts. The fair value of the US$1 billion notes issue is based on listed market prices.

South Deep dividend

The carrying amount approximates the fair value.

Gold, oil and copper derivative contracts

The fair value of these contracts are determined by using available market contract values for each trading date’s settlement volume.

The Group uses the following hierarchy for measuring the fair value of assets and liabilities at the reporting date:

Level 1: unadjusted quoted prices in active markets for identical assets or liabilities;

Level 2: inputs other than quoted prices in level 1 that are observable for the asset or liability, either directly (as prices) or indirectly (derived from prices); and

Level 3: inputs for the asset or liability that are not based on observable market data (unobservable inputs).

The Group recognises transfers between levels of the fair value hierarchy at the end of the reporting period during which the change has occurred. There were no transfers during the years ended 31 December 2017 and 2016.

The following table sets out the Group’s assets and liabilities measured at fair value by level within the fair value hierarchy at the reporting date:

Risk Management Activities

37. RISK MANAGEMENT ACTIVITIES

In the normal course of its operations, the Group is exposed to commodity price, currency, interest rate, liquidity, equity price and credit risk. In order to manage these risks, the Group has developed a comprehensive risk management process to facilitate control and monitoring of these risks.

Controlling and managing risk in the Group

Gold Fields has policies in areas such as counterparty exposure, hedging practices and prudential limits which have been approved by Gold Fields’ Board of Directors. Management of financial risk is centralised at Gold Fields’ treasury department (“Treasury”), which acts as the interface between Gold Fields’ operations and counterparty banks. Treasury manages financial risk in accordance with the policies and procedures established by the Gold Fields’ Board of Directors and Executive Committee.

Gold Fields’ Board of Directors has approved dealing limits for money market, foreign exchange and commodity transactions, which Gold Fields’ Treasury is required to adhere to. Among other restrictions, these limits describe which instruments may be traded and demarcate open position limits for each category as well as indicating counterparty credit related limits. The dealing exposure and limits are checked and controlled each day and reported to the Chief Financial Officer.

The objective of Treasury is to manage all financial risks arising from the Group’s business activities in order to protect profit and cash flows. Treasury activities of Gold Fields Limited and its subsidiaries are guided by the Treasury Policy, the Treasury Framework as well as domestic and international financial market regulations. Treasury activities are currently performed within the Treasury Framework with appropriate resolutions from the Board of Gold Fields Limited, which are reviewed and approved annually by the Audit Committee.

The financial risk management objectives of the Group are defined as follows:

Liquidity risk management: The objective is to ensure that the Group is able to meet its short-term commitments through the effective and efficient usage of credit facilities and cash resources.

Currency risk management: The objective is to maximise the Group’s profits by minimising currency fluctuations.

Funding risk management: The objective is to meet funding requirements timeously and at competitive rates by adopting reliable liquidity management procedures.

Investment risk management: The objective is to achieve optimal returns on surplus funds.

Interest rate risk management: The objective is to identify opportunities to prudently manage interest rate exposures.

Counterparty exposure: The objective is to only deal with approved counterparts that are of a sound financial standing and who have an official credit rating. The Group is limited to a maximum investment of 2.5% of the financial institutions’ equity, which is dependent on the institutions’ credit rating. The credit rating used is Fitch Ratings’ short-term credit rating for financial institutions.

Commodity price risk management: Commodity price risk management takes place within limits and with counterparts as approved in the Treasury Framework.

Operational risk management: The objective is to implement controls to adequately mitigate the risk of error and/or fraud.

Banking relations management: The objective is to maintain relationships with credible financial institutions and ensure that all contracts and agreements related to risk management activities are co-ordinated and consistent throughout the Group and that they comply where necessary with all relevant regulatory and statutory requirements.

Credit risk

Credit risk represents risk that an entity will suffer a financial loss due to the other party of a financial instrument not discharging its obligation.

The Group has reduced its exposure to credit risk by dealing with a number of counterparties. The Group approves these counterparties according to its risk management policy and ensures that they are of good credit quality.

Receivables are reviewed on a regular basis and an allowance for impairment is raised when they are not considered recoverable.

The combined maximum credit risk exposure of the Group is as follows:

	UNITED STATES DOLLAR
	2017		2016
Environmental trust funds		55.5		44.5
Trade and other receivables		66.5		68.5
Cash and cash equivalents		479.0		526.7

Trade receivables comprise banking institutions purchasing gold bullion and refineries purchasing copper concentrate. These receivables are in a sound financial position and no impairment has been recognised. Trade and other receivables above exclude VAT, import duties, prepayments, payroll receivables, derivative contracts and diesel rebates amounting to US$135.4 million (2016: US$101.7 million). Receivables that are past due but not impaired total US$nil (2016: US$nil). At 31 December 2017, receivables of US$0.1 million (2016: US$0.2 million) are considered impaired and are provided for. Concentration of credit risk on cash and cash equivalents and non-current assets is considered minimal due to the above mentioned investment risk management and counterparty exposure risk management policies.

Liquidity risk

In the ordinary course of business, the Group receives cash proceeds from its operations and is required to fund working capital and capital expenditure requirements. The cash is managed to ensure surplus funds are invested to maximise returns while ensuring that capital is safeguarded to the maximum extent possible by investing only with top financial institutions.

Uncommitted borrowing facilities are maintained with several banking counterparties to meet the Group’s normal and contingency funding requirements.

The following are the contractually due undiscounted cash flows resulting from maturities of all financial liabilities, including interest payments:

4 ZAR borrowings – Spot JIBAR (one month fix) rate adjusted by specific facility agreement: 6.908% and bank overnight borrowing rate on uncommitted credit facilities: average of 8.3% (2016: 8.3%).

5 Although environmental rehabilitation costs do not meet the definition of a financial liability, the Group included the gross closure cost estimate in the undiscounted cash flows as it represents a future cash outflow (refer note 25.1). In South Africa and Ghana, US$55.5 million (2016: US$44.5 million) of the environmental rehabilitation costs is funded through the environmental trust funds.

Market risk

Gold Fields is exposed to market risks, including foreign currency, commodity price, equity securities price and interest rate risk associated with underlying assets, liabilities and anticipated transactions. Following periodic evaluation of these exposures, Gold Fields may enter into derivative financial instruments to manage some of these exposures.

IFRS 7 sensitivity analysis

IFRS 7 requires sensitivity analysis that shows the effects of reasonably possible changes of relevant risk variables on profit or loss or shareholders’ equity. The Group is exposed to commodity price, currency, interest rate and equity price risks. The effects are determined by relating the reasonably possible change in the risk variable to the balance of financial instruments at reporting date.

The amounts generated from the sensitivity analysis below are forward looking estimates of market risks assuming certain adverse or favourable market conditions occur. Actual results in the future may differ materially from those projected results and therefore should not be considered a projection of likely future events and gains/losses.

Foreign currency sensitivity

General and policy

In the ordinary course of business, Gold Fields enters into transactions, such as gold sales, denominated in foreign currencies, primarily US Dollar. In addition, Gold Fields has investments and indebtedness in US Dollar, as well as South African Rand.

Gold Fields may from time to time establish currency financial instruments to protect underlying cash flows.

Gold Fields’ revenues and costs are very sensitive to the Australian Dollar/US Dollar and South African Rand/US Dollar exchange rates because revenues are generated using a gold price denominated in US Dollar, while costs of the Australian and South African operations are incurred principally in Australian Dollar and South African Rand, respectively. Depreciation of the Australian Dollar and/or South African Rand against the US Dollar reduces Gold Fields’ average costs when they are translated into US Dollar, thereby increasing the operating margin of the Australian and/or South African operations. Conversely, appreciation of the Australian Dollar and/or South African Rand results in Australian and/or South African operating costs increasing when translated into US Dollar, resulting in lower operating margins. The impact on profitability of changes in the value of the Australian Dollar and South African Rand against the US Dollar could be substantial.

Although this exposes Gold Fields to transaction and translation exposure from fluctuations in foreign currency exchange rates, Gold Fields does not generally hedge its foreign currency exposure, although it may do so in specific circumstances, such as financing projects or acquisitions. Also, Gold Fields on occasion undertakes currency hedging to take advantage of favourable short-term fluctuations in exchange rates when management believes exchange rates are at unsustainable levels.

Currency risk only exists on account of financial instruments being denominated in a currency that is not the functional currency and being of a monetary nature. The Group had no significant exposure to currency risk relating to financial instruments at 31 December 2017 and 2016. Differences resulting from the translation of financial statements into the Group’s presentation currency are not taken into account.

Foreign currency hedging experience

On 25 February 2016, South Deep entered into US$/Rand forward exchange contracts for a total delivery of US$69.8 million starting at July 2016 to December 2016. The average forward rate achieved over the six-month period was R16.8273. The hedge was delivered into in July and in August and the balance closed out in September 2016. The average rate achieved on delivery and close out was R13.8010, resulting in a profit of R211.2 million (US$14.4 million). At 31 December 2017 and 2016, there were no material foreign currency contract positions.

Commodity price hedging policy

Gold and copper

The market prices of gold and to a lesser extent copper have a significant effect on the results of operations of Gold Fields, the ability of Gold Fields to pay dividends and undertake capital expenditures, and the market price of Gold Fields’ ordinary shares. Gold and copper prices have historically fluctuated widely and are affected by numerous industry factors over which Gold Fields does not have any control. The aggregate effect of these factors on the gold and copper price, all of which are beyond the control of Gold Fields, is impossible for Gold Fields to predict.

Oil

The market price of oil has a significant effect on the results of the offshore operations of Gold Fields. The offshore operations consume large quantities of diesel in the running of their mining fleets. Oil prices have historically fluctuated widely and are affected by numerous factors over which Gold Fields does not have any control.

Commodity price hedging experience

The Group’s policy is to remain unhedged to the gold and copper price. However, hedges are sometimes undertaken as follows:

• to protect cash flows at times of significant expenditure;

• for specific debt servicing requirements; and

• to safeguard the viability of higher cost operations.

To the extent that it enters into commodity hedging arrangements, Gold Fields seeks to use different counterparty banks consisting of local and international banks to spread risk. None of the counterparties is affiliated with, or related parties of, Gold Fields.

Gold and copper

In November 2017, South Deep entered into zero-cost collars for the period January 2018 to December 2018 for 63,996 ounces of gold. The strike prices are R600,000 per kilogram on the floor and R665,621 per kilogram on the cap. At 31 December 2017, the mark-to-market value of the hedge was a positive US$10.9 million.

In April 2017 and June 2017, the Australian operations entered into a combination of zero-cost collars and forward sales transactions for the period July 2017 to December 2017 for 295,000 ounces of gold. The average strike prices on the collars were A$1,695.9 per ounce on the floor and A$1,754.2 per ounce on the cap. The average forward price was A$1,719.9 per ounce. At ³¹ December 2017, there were no open positions and the total realised gain was US$15.3 million.

In July 2017, Peru entered into zero-cost collars for the period August 2017 and December 2017 for 8,250 tonnes of copper. The average floor price was US$5,867 per tonne and the average cap was US$6,300 per tonne. In November 2017, further zero-cost collars were entered into for the period January 2018 to December 2018. A total volume of 29,400 tonnes was hedged, at an average floor price of US$6,600 per tonne and an average cap price of US$7,431 per tonne. At 31 December 2017, the mark-to-market value on the hedge was a negative US$3.3 million.

Oil

In May 2017 and June 2017, the Ghanaian operations entered into fixed price ICE Gasoil cash settled swap transactions for a total of 125.8 million litres of diesel for the period June 2017 to December 2019. The average swap price is US$457.2 per metric tonne (equivalent US$61.4 per barrel). At the time of the transactions, the average Brent swap equivalent over the tenor was US$49.8 per barrel. At 31 December 2017, the mark-to-market value on the hedge was a positive US$9.0 million.

In May 2017 and June 2017, the Australian operations entered into fixed price Singapore 10ppm Gasoil cash settled swap transactions for a total of 77.5 million litres of diesel for the period June 2017 to December 2019. The average swap price is US$61.15 per barrel. At the time of the transactions, the average Brent swap equivalent over the tenor was US$49.92 per barrel. At 31 December 2017, the mark-to-market value on the hedge was a positive US$5.1 million.

Equity securities price risk

General

The Group is exposed to equity securities price risk because of investments held by the Group which are classified as available-for-sale. To manage its price risk arising from investments in equity securities, the Group diversifies its portfolio. Diversification of the portfolio is done in accordance with limits set by the Group.

The Group’s equity investments are publicly traded and are listed on one of the following exchanges:

• JSE Limited

• Toronto Stock Exchange

• Australian Stock Exchange

• London Stock Exchange

The table below summarises the impact of increases/decreases of the exchanges on the Group’s shareholders’ equity in case of shares (sensitivity to equity security price). The analysis is based on the assumption that the share prices quoted on the exchange have increased/decreased with all other variables held constant and the Group’s investments moved according to the historical correlation with the index.

	UNITED STATES DOLLAR
	(Decrease)/increase in equity price
	(10.0%)			(5.0%)			5.0%		10.0%

1 Spot rate: R12.58 = US$1.00 (2016: R14.03 = US$1.00).

Interest rate sensitivity

General

As Gold Fields has no significant interest-bearing assets, the Group’s income and operating cash flows are substantially independent of changes in market interest rates. Gold Fields’ interest rate risk arises from borrowings.

As of 31 December 2017, Gold Fields’ borrowings amounted to US$1,781.5 million (2016: US$1,692.9 million). Gold Fields generally does not undertake any specific action to cover its exposure to interest rate risk, although it may do so in specific circumstances.

Interest rate sensitivity analysis

The portion of Gold Fields’ interest-bearing borrowings at year-end that is exposed to interest rate fluctuations is US$933.6 million (2016: US$846.5 million). These borrowings are normally rolled for periods between one and three months and are therefore exposed to the rate changes in this period. The remainder of the borrowings bear interest at a fixed rate.

US$508.5 million (2016: US$785.5 million) of the total borrowings at reporting date is exposed to changes in the LIBOR rate, US$79.5 million (2016: US$nil) is exposed to the JIBAR rate, US$114.1 million (2016: US$61.0 million) is exposed to the South African Prime (“Prime”) interest rate and US$231.5 million (2016: US$nil) is exposed to the BBSY rate. The relevant interest rates for each facility are described in note 24.

The table below summarises the effect of a change in finance expense on the Group’s profit or loss had LIBOR, JIBAR, Prime and BBSY differed as indicated (sensitivity to interest rates). The analysis is based on the assumption that the applicable interest rate increased/decreased with all other variables held constant. All financial instruments with fixed interest rates that are carried at amortised cost are not subject to the interest rate sensitivity analysis.

Capital Management

38. CAPITAL MANAGEMENT

The primary objective of managing the Group’s capital is to ensure that there is sufficient capital available to support the funding requirements of the Group, including capital expenditure, in a way that:

• optimises the cost of capital;

• maximises shareholders’ returns; and

• ensures that the Group remains in a sound financial position.

There were no changes to the Group’s overall capital management approach during the current year.

The Group manages and makes adjustments to the capital structure as and when borrowings mature or as and when funding is required. This may take the form of raising equity, market or bank debt or hybrids thereof. Opportunities in the market are also monitored closely to ensure that the most efficient funding solutions are implemented.

The Group monitors capital using the ratio of net debt to adjusted EBITDA. Adjusted EBITDA is defined as profit or loss for the year adjusted for interest, taxation, amortisation and depreciation and certain other costs. The definition of adjusted EBITDA is as defined in the US$1,290 million term loan and revolving credit facilities agreement. Net debt is defined as total borrowings less cash and cash equivalents. The Group’s long-term target is a ratio of net debt to adjusted EBITDA of one times or lower. The bank covenants on external borrowings require a net debt to adjusted EBITDA ratio of 2.5 or below and the ratio is measured based on amounts in United States Dollar.

Correction of Methodology

40. CORRECTION OF METHODOLOGY

During the year ended 31 December 2017, the Group corrected the amortisation methodology for the mineral rights asset at the Australian operations to reduce the level of estimation required in calculating amortisation. Prior to the correction of the methodology, the total mineral rights asset capitalised at the Australian operation was depreciated on a units-of-production basis over a useful life that exceeded proved and probable reserves. The amortisation estimation methodology was corrected in order to divide the total mineral rights asset capitalised at the respective operations into a depreciable and a non-depreciable component. The mineral rights are initially capitalised to the mineral rights asset as a non-depreciable component. The depreciable component is amortised over the estimated proved and probable ore reserves on a units-of-production method. For further details, refer to accounting policies pages 144 to 145.

As a result of this correction of the methodology, management identified an understatement of the amortisation and depreciation charge relating to prior periods. In order to assess the impact of the understatement, the Group applied SEC Staff Accounting Bulletin (“SAB”) No 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements. SAB No 108 states that registrants must quantify the impact of correcting all misstatements on all periods presented, including both the carryover (iron curtain method) and reversing (rollover method) effects of prior year misstatements on the current year financial statements, and by evaluating the misstatement measured under each method in light of quantitative and qualitative factors.

Under SAB No 108, prior year misstatements which, if corrected in the current year would be material to the current year, must be corrected by adjusting prior year financial statements, even though such correction previously was and continues to be immaterial to the prior year financial statements. Correcting prior year financial statements for such immaterial errors does not require previously issued or filed financial statements to be amended.

In accordance with SAB No 99 Materiality, the Group assessed the materiality of the understatement and concluded that it was not material to any of the Group’s previously issued or filed financial statements taken as a whole. The cumulative understatement was material in 2017 if corrected in the current year.

The conclusions above in terms of SAB No 99 and No 108 are consistent with the requirements of IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors, as well as principles of IFRS. As a result, the immaterial misstatements were corrected by restating each of the affected financial statement line items for prior periods (all unaffected financial statement line items have been grouped together as “other”).

The following table summarises the cumulative impact of the correction of the amortisation methodology:

	Property, plant and equipment												Deferred tax balance1												Equity

The above is a geographical analysis presented by location of assets.

The Group’s continuing operations are primarily involved in gold mining, exploration and related activities. Activities are conducted and investments held both inside and outside South Africa. The segment results have been prepared and presented based on management’s reporting format. Gold mining operations are managed and internally reported based on the following geographical areas: in South Africa, South Deep mine, in Ghana, Tarkwa and Damang mines, in Australia, St Ives, Agnew/Lawlers, Granny Smith and Gruyere Gold Project and in Peru, the Cerro Corona mine. While the Gruyere Gold Project does not meet the quantitative criteria for disclosure as a separate segment, it is expected to become a significant contributor to the Group’s performance in future years as the project is being developed. The Group also has exploration interests which are included in the “Corporate and other” segment. Refer to accounting policies on segment reporting on page 151.

The Group’s discontinued operation was primarily involved in gold mining, exploration and related activities. Activities are conducted and investments held in Australia.

US Dollar figures may not add as they are rounded independently.

1 The income statement and statement of financial position of South Deep is that of the operating mine and does not include any of the adjustments made in respect of the purchase price allocation relating to the acquisition of South Deep (refer note 14). South Deep Gold mine, being an unincorporated joint venture, is not liable for taxation. Taxation included in South Deep is indicative, as tax is provided in the holding companies at a rate of 30%.

2 “Corporate and other” represents the items to reconcile segment data to consolidated financial statement totals, including the elimination of intercompany transactions and balances as well as the Group’s exploration interests. This does not represent a separate segment as it does not generate revenue. Included in “Corporate and other” is the adjustment made in respect of the purchase price allocation, including goodwill relating to the acquisition of South Deep.

3 Other costs “Corporate and other” comprise share of loss of associates, net of taxation of US$1.3 million and the balance of US$9.0 million consists mainly of corporate related costs.

4 The Australian operations are entitled to transfer and off-set profits and losses from one company to another, therefore it is not meaningful to split the royalties, income or deferred taxation.

The above is a geographical analysis presented by location of assets.

The Group’s continuing operations are primarily involved in gold mining, exploration and related activities. Activities are conducted and investments held both inside and outside South Africa. The segment results have been prepared and presented based on management’s reporting format. Gold mining operations are managed and internally reported based on the following geographical areas: in South Africa, South Deep mine, in Ghana, Tarkwa and Damang mines, in Australia, St Ives, Agnew/Lawlers, Granny Smith and Gruyere Gold Project and in Peru, the Cerro Corona mine. While the Gruyere Gold Project does not meet the quantitative criteria for disclosure as a separate segment, it is expected to become a significant contributor to the Group’s performance in future years as the project is being developed. The Group also has exploration interests which are included in the “Corporate and other” segment. Refer to accounting policies on segment reporting on page 151.

The Group’s discontinued operation was primarily involved in gold mining, exploration and related activities. Activities are conducted and investments held in Australia.

US Dollar figures may not add as they are rounded independently.

1 The income statement and statement of financial position of South Deep is that of the operating mine and does not include any of the adjustments made in respect of the purchase price allocation relating to the acquisition of South Deep (refer note 14). South Deep Gold mine, being an unincorporated joint venture, is not liable for taxation. Taxation included in South Deep is indicative, as tax is provided in the holding companies at a rate of 30%.

2 “Corporate and other” represents the items to reconcile segment data to consolidated financial statement totals, including the elimination of intercompany transactions and balances as well as the Group’s exploration interests. This does not represent a separate segment as it does not generate revenue. Included in “Corporate and other” is the adjustment made in respect of the purchase price allocation, including goodwill relating to the acquisition of South Deep.

3 Other costs “Corporate and other” comprise share of loss of associates net of taxation of US$2.3 million, profit on disposal of investments of US$2.3 million and the balance of US$23.1 million consists mainly of corporate related costs.

4 The Australian operations are entitled to transfer and off-set profits and losses from one company to another, therefore it is not meaningful to split the royalties, income or deferred taxation.

BASIS OF PREPARATION

1. BASIS OF PREPARATION

The financial statements of the Group have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”), the SAICA Financial Reporting Guides as issued by the Accounting Practices Committee and Financial Reporting Pronouncements as issued by the Financial Reporting Standards Council, as well as the requirements of the South African Companies Act. The consolidated financial statements have been prepared under the historical cost convention, as modified by available-for-sale financial assets, assets held for sale and financial assets and liabilities (including derivative instruments), which have been brought to account at fair value through profit or loss or through other comprehensive income.

As required by the United States Securities and Exchange Commission, the financial statements include the consolidated statements of financial position as at 31 December 2017 and 2016, and the consolidated income statements and statements of comprehensive income, changes in equity and cash flows for the years ended 31 December 2017, 2016 and 2015 and the related notes.

The consolidated financial statements were authorised for issue by the Board of Directors on 27 March 2018.

Standards, interpretations and amendments to published standards effective for the year ended 31 December 2017

During the financial year, the following new and revised accounting standards, amendments to standards and new interpretations were adopted by the Group:

Standard(s) Amendment(s) Interpretation(s)	Nature of the Change	Salient features of the changes	Impact on financial position or performance
IAS 7 Statement of cash flows	Amendments	•  The amendments require disclosures that enable users of financial statements to evaluate changes in liabilities arising from financing activities, including both changes arising from cash flow and non-cash changes.	No impact
IAS 12 Income taxes	Amendments	•  The amendments provide additional guidance on the existence of deductible temporary differences; and •  The amendments also provide additional guidance on the methods used to calculate future taxable profit to establish whether a deferred tax asset can be recognised.	No impact

Standards, interpretations and amendments to published standards which are not yet effective

Certain new standards, amendments and interpretations to existing standards have been published that apply to the Group’s accounting periods beginning on 1 January 2018 or later periods but have not been early adopted by the Group.

These standards, amendments and interpretations that are relevant to the Group are:

Standard(s) Amendment(s) Interpretation(s)	Nature of the Change		Salient features of the changes	Effective date*
IFRS 2 Share-based payments		Amendments	•  The amendments cover three accounting areas: -  Measurement of cash-settled share-based payments; -  Classification of share-based payments settled net of tax withholdings; and -  Accounting for a modification of a share-based payment from cash-settled to equity-settled. •  The amendment does not have a material impact on the Group.		1 January 2018
IFRS 9 Financial Instruments		New standard	•  This IFRS sets out requirements for recognising and measuring financial assets, financial liabilities and some contracts to buy or sell non-financial items. This standard replaces IAS 39 Financial Instruments. The Group will adopt IFRS 9 on 1 January 2018; •  This IFRS contains a new classification and measurement approach for financial assets that reflects the business model in which the assets are managed and their cash flow characteristics. The three principal		1 January 2018
			classification categories for financial assets are: measured at amortised cost, fair value through profit or loss (“FVTPL”) and fair value through other comprehensive income (“FVOCI”); •  Based on the Group’s assessment, the Group believes that the new classification if applied at 31 December 2017, would not have a significant impact on its accounting for financial assets. The Group’s available-for-sale financial assets will be designated at FVOCI; and •  The new measurement principles will not have a material impact on the Group.
IFRS 15 Revenue from contracts with customers		New standard	•  This IFRS introduces a new revenue recognition model for contracts with customers and establishes a comprehensive framework for determining whether, how much and when revenue is recognised. IFRS 15 also includes extensive new disclosure requirements; •  The Group has assessed the impact of adopting IFRS 15 and has determined the impact as follows: •  Revenue will be recognised when the customer takes control of the gold, copper and silver. The timing of recognition of revenue will no longer be when risks and rewards of ownership pass to the customer; •  The change in timing of revenue recognition will result in revenue at the South African and Australian operations being recognised on settlement date (date when control passes) and not contract date (previous date when risks and rewards of ownership pass). There is no change to the revenue recognition at any of the other operations given that the date of control is the same date as when risks and rewards of ownership pass. The change in timing of revenue recognition for the South African and Australian operations will be that revenue will be recognised approximately two days later than it currently is recognised. As approximately 0.3% of 2017 revenue will		1 January 2018
			now be recognised in 2018, the adoption of IFRS 15 will not have a material impact on the revenue of the Group; and •  The Group will adopt IFRS 15 using the cumulative effect method, with the effect of initially applying this standard at the date of initial application (i.e. 1 January 2018). As a result, the Group will not apply the requirements of IFRS 15 to the comparative periods presented.
IFRS 16 Leases		New standard	•  This IFRS sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract, i.e. the customer (‘lessee’) and the supplier (‘lessor’); •  IFRS 16 replaces the previous leases Standard, IAS 17 Leases, and related Interpretations; •  IFRS 16 has one model for lessees which will result in almost all leases being included on the statement of financial position. No significant changes have been included for lessors; and •  Management has commenced compiling a list of all potential leases and is in the process of reviewing all such contracts in order to assess the impact the standard will have on the Group.	1 January 2019
IFRIC 23 Uncertainty over Income Tax Treatments		New interpretation	•  This interpretation clarifies the accounting for income tax treatments that have yet to be accepted by tax authorities; •  IFRIC 23 specifically clarifies how to incorporate this uncertainty into the measurement of tax as reported in the financial statements; •  IFRIC 23 does not introduce any new disclosures but reinforces the need to comply with existing disclosure requirements about judgements made, assumptions and other estimates used and the potential impact of uncertainties that are not reflected •  The interpretation will not have a material impact on the Group.	1 January 2019

* Effective date refers to annual period beginning on or after said date.

Significant accounting judgements and estimates

Use of estimates: The preparation of the financial statements in accordance with IFRS requires the Group’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The determination of estimates requires the exercise of judgement based on various assumptions and other factors such as historical experience, current and expected economic conditions, and in some cases actuarial techniques. Actual results could differ from those estimates.

The more significant areas requiring the use of management estimates and assumptions relate to mineral reserves and resources that are the basis of future cash flow estimates used for impairment assessments and units-of-production depreciation and amortisation calculations, asset impairments, production start date, estimates of recoverable gold and other materials in heap leach and stockpiles inventories, write-downs of inventory to net realisable value, provision for environmental rehabilitation costs, provision for silicosis settlement costs, income taxes, share-based payments, the fair value and accounting treatments of derivative financial instruments, contingencies and business combinations.

Estimates and judgements are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances.

The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the financial year are discussed below.

Mineral reserves and resources estimates

Mineral reserves are estimates of the amount of product, inclusive of diluting materials and allowances for losses, which can be economically and legally extracted from the Group’s properties, as determined by life-of-mine schedules or pre-feasibility studies.

Mineral resources are estimates, based on specific geological evidence and knowledge, including sampling, of the amount of product in situ, for which there is a reasonable prospect for eventual legal and economic extraction.

In order to calculate the reserves and resources, estimates and assumptions are required about a range of geological, technical and economic factors, including but not limited to quantities, grades, production techniques, recovery rates, production costs, capital expenditure, transport costs, commodity demand, commodity prices and exchange rates.

Estimating the quantity and grade of the mineral reserves and resources is based on exploration and sampling information gathered through appropriate techniques (primarily diamond drilling, reverse circulation drilling, air-core and sonic drilling), surface three-dimensional reflection seismics, ore body faces modelling, structural modelling, geological mapping, detailed ore zone wireframes and geostatistical estimation. This process may require complex and difficult geological judgements and calculations to interpret the data.

The Group is required to determine and report on the mineral reserves and resources in accordance with the South African Mineral Resource Committee (“SAMREC”) code on an annual basis.

Estimates of mineral reserves and resources may change from year to year due to the change in economic, regulatory, infrastructural or social assumptions used to estimate ore reserves and resources, and due to additional geological data becoming available.

Changes in reported proven and probable reserves may affect the Group’s financial results and position in a number of ways, including the following:

• The recoverable amount used in the impairment calculations may be affected due to changes in estimated cash flows or timing thereof;

• Amortisation and depreciation charges to profit or loss may change as these are calculated on the units-of-production method, or where the useful economic lives of assets change;

• Provision for environmental rehabilitation costs may change where changes in ore reserves affect expectations about the timing or cost of these activities; and

• The carrying value of deferred tax assets may change due to changes in estimates of the likely recovery of the tax benefits.

Changes in reported measured and indicated resources may affect the Group’s financial results and position in a number of ways, including the following:

• The recoverable amount used in the impairment calculations may be affected due to changes in estimated market value of resources exclusive of reserves; and

• Amortisation and depreciation charges for the mineral rights asset at the Australian operations may change as a result of the change in the portion of mineral rights asset being transferred from the non-depreciable component to the depreciable component.

Carrying value of property, plant and equipment and goodwill

All mining assets are amortised using the units-of-production method where the mine operating plan calls for production from proved and probable mineral reserves.

Mobile and other equipment are depreciated over the shorter of the estimated useful life of the asset or the estimate of mine life based on proved and probable mineral reserves.

The calculation of the units-of-production rate of amortisation could be impacted to the extent that actual production in the future is different from current forecast production based on proved and probable mineral reserves. This would generally result from the extent that there are significant changes in any of the factors or assumptions used in estimating mineral reserves. These factors could include:

• Changes in proved and probable mineral reserves;

• Differences between actual commodity prices and commodity price assumptions;

• Unforeseen operational issues at mine sites;

• Changes in capital, operating, mining, processing and reclamation costs, discount rates and foreign currency exchange rates; and

• Changes in mineral reserves could similarly impact the useful lives of assets depreciated on a straight-line basis, where those lives are limited to the life of the mine.

The Group reviews and tests the carrying value of long-lived assets annually or when events or changes in circumstances suggest that the carrying amount may not be recoverable by comparing the recoverable amounts to these carrying values. In addition, goodwill is tested for impairment on an annual basis. Assets are grouped at the lowest level for which identifiable cash flows are largely independent of cash flows of other assets and liabilities. If there are indications that impairment may have occurred, estimates are prepared of recoverable amounts of each group of assets. The recoverable amounts of cash-generating units (“CGU”) and individual assets have been determined based on the higher of value-in-use and fair value less cost of disposal (“FVLCOD”) calculations. Expected future cash flows used to determine the value in use or FVLCOD of property, plant and equipment and goodwill are inherently uncertain and could materially change over time. They are significantly affected by a number of factors including reserves and production estimates, together with economic factors such as the gold and copper prices, discount rates, foreign currency exchange rates, resource valuations (determined based on comparable market transactions), estimates of costs to produce reserves and future capital expenditure.

An individual operating mine does not have an indefinite life because of the finite life of its reserves. The allocation of goodwill to an individual mine will result in an eventual goodwill impairment due to the wasting nature of the mine. In accordance with the provisions of IAS 36 Impairment of Assets, the Group performs its annual impairment review of goodwill at each financial year-end.

The Group generally used FVLCOD to determine the recoverable amount of each CGU.

Significant assumptions used in the Group’s impairment assessments (FVLCOD calculations) include:

1 Due to the availability of unredeemed capital for tax purposes over several years into the life of the South Deep mine, nominal cash flows are used for South Africa. In order to determine nominal cash flows in South Africa, costs are inflated by the current South African inflation rate. Cash flows for all other operations are in real terms and as a result are not inflated.

The FVLCOD calculations are very sensitive to the gold price assumptions and an increase or decrease in the gold price could materially change the FVLCOD.

Should there be a significant decrease in the gold price, the Group would take actions to assess the implications on the life-of-mine plans, including the determination of reserves and resources and the appropriate cost structure for the CGUs.

The carrying amount of property, plant and equipment at 31 December 2017 was US$4,892.9 million (2016: US$4,524.6 million and 2015: US$4,295.6 million). The carrying value of goodwill at 31 December 2017 was US$76.6 million (2016: US$317.8 million and 2015: US$295.3 million).

An impairment of US$277.8 million (2016: US$nil and 2015: US$nil) was recognised in respect of the South Deep CGU at 31 December 2017.

Production start date

The Group assesses the stage of each mine construction project to determine when a mine moves into the production stage. The criteria used to assess the start date are determined based on the unique nature of each mine construction project. The Group considers various relevant criteria to assess when the mine is substantially complete, ready for its intended use and moves into the production stage. Some of the criteria would include, but are not limited to the following:

• The level of capital expenditure compared to the construction cost estimates;

• Ability to produce metal in saleable form (within specifications); and

• Ability to sustain commercial levels of production of metal.

When a mine construction project moves into the production stage, the capitalisation of certain mine construction costs ceases and costs are either regarded as inventory or expensed, except for capitalisable costs related to mining asset additions or improvements, underground mine development, deferred stripping activities or ore reserve development.

Stockpiles, gold in process and product inventories

Costs that are incurred in or benefit the productive process are accumulated as stockpiles, gold in process, ore on leach pads and product inventories. Net realisable value tests are performed on a monthly basis for short-term stockpiles, gold in process and product inventories and at least annually for long-term stockpiles and represent the estimated future sales price of the product based on prevailing spot metals prices at the reporting date, less estimated costs to complete production and bring the product to sale. If any inventories are expected to be realised in the long term, estimated future sales prices are used for valuation purposes.

Stockpiles are measured by estimating the number of tonnes added and removed from the stockpile, the number of contained gold ounces based on assay data, and the estimated recovery percentage based on the expected processing method. Stockpile tonnages are verified by periodic surveys.

Although the quantities of recoverable metal are reconciled by comparing the grades of ore to the quantities of metals actually recovered (metallurgical balancing), the nature of the process inherently limits the ability to precisely monitor the recoverability levels. As a result, the metallurgical balancing process is constantly monitored and engineering estimates are refined based on actual results over time.

Variations between actual and estimated quantities resulting from changes in assumptions and estimates that do not result in write downs to net realisable value are accounted for on a prospective basis.

The carrying amount of total gold-in-process and stockpiles (non-current and current) at 31 December 2017 was US$305.4 million (2016: US$234.3 million).

Provision for environmental rehabilitation costs

The Group’s mining and exploration activities are subject to various laws and regulations governing the protection of the environment. The Group recognises management’s best estimate for the provision of environmental rehabilitation costs in the period in which they are incurred. Actual costs incurred in future periods could differ materially from the estimates. Additionally, future changes to environmental laws and regulations, life-of-mine estimates and discount rates could affect the carrying amount of this provision.

Refer note 25.1 of the consolidated financial statements for details of key assumptions used to estimate the provision.

The carrying amounts of the provision for environmental rehabilitation costs at 31 December 2017 was US$281.5 million (2016: US$283.1 million).

Provision for silicosis settlement costs

The Group has an obligation in respect of a possible settlement of the silicosis class action claims and related costs. The Group recognises management’s best estimate for the provision of silicosis settlement costs.

The ultimate outcome of the class action remains uncertain, with a possible failure to reach a settlement or to obtain the requisite court approval for a potential settlement. The provision is consequently subject to adjustment in the future, depending on the progress of the Working Group discussions, stakeholder engagements and the ongoing legal proceedings.

Refer notes 25.3 and 34 of the consolidated financial statements for further details.

The carrying amounts of the provision for silicosis settlement costs at 31 December 2017 was US$31.9 million (2016: US$nil).

Income taxes

The Group is subject to income taxes in numerous jurisdictions. Significant judgement is required in determining the liability for income taxes due to the complexity of legislation. There are many transactions and calculations for which the ultimate tax determination is uncertain during the ordinary course of business. The Group recognises liabilities for anticipated tax audit issues based on estimates of whether additional taxes will be due. Where the final tax outcome of these matters is different from the amounts that were initially recorded, such differences will impact the income tax and deferred tax provisions in the period in which such determination is made.

The Group recognises the future tax benefits related to deferred income tax assets to the extent that it is probable that the deductible temporary differences will reverse in the foreseeable future. Assessing the recoverability of deferred income tax assets requires the Group to make significant estimates related to expectations of future taxable income. Estimates of future taxable income are based on forecast cash flows from operations and the application of existing tax laws in each jurisdiction. To the extent that future cash flows and taxable income differ significantly from estimates, the ability of the Group to realise the net deferred tax assets recorded at the reporting date could be impacted.

Additionally, future changes in tax laws in the jurisdictions in which the Group operates could limit the ability of the Group to obtain tax deductions in future periods.

Carrying values at 31 December 2017:

• Deferred taxation liability: US$453.9 million (2016: US$458.6 million and 2015: US$482.2 million)

• Deferred taxation asset: US$72.0 million (2016: US$48.7 million and 2015: US$54.1 million)

• Taxation payable: US$77.5 million (2016: US$107.9 million)

Refer note 9 for details of unrecognised deferred tax assets.

Share-based payments

The Group issues equity-settled share-based payments to executive directors, certain officers and employees. The fair value of these instruments is measured at grant date, using the Black-Scholes and Monte Carlo simulation valuation models, which require assumptions regarding the estimated term of the option, share price volatility and expected dividend yield. While Gold Fields’ management believes that these assumptions are appropriate, the use of different assumptions could have a material impact on the fair value of the option granted and the related recognition of the share-based payments expense in the consolidated income statement. Gold Fields’ options have characteristics significantly different from those of traded options and therefore fair values may also differ.

The income statement charge from continuing operations for the year ended 31 December 2017 was US$26.8 million (2016: US$14.0 million and 2015: US$10.7 million).

Financial instruments

The estimated fair value of financial instruments is determined at discrete points in time, based on the relevant market information. The fair value is calculated with reference to market rates using industry valuation techniques and appropriate models. The carrying values of derivative financial instruments included in trade and other receivables at 31 December 2017 was US$25.0 million (2016: US$nil) and included in trade and other payables US$3.3 million (2016: US$nil).

Contingencies

By their nature, contingencies will only be resolved when one or more future events occur or fail to occur. The assessment of such contingencies inherently involves the exercise of significant judgement and estimates of the outcome of future events. Such contingencies include, but are not limited to environmental obligations, litigation, regulatory proceedings, tax matters and losses resulting from other events and developments.

When a loss is considered probable and reasonably estimable, a liability is recorded based on the best estimate of the ultimate loss. The likelihood of a loss with respect to a contingency can be difficult to predict and determining a meaningful estimate of the loss or a range of losses may not always be practicable based on the information available at the time and the potential effect of future events and decisions by third parties that will determine the ultimate resolution of the contingency. It is not uncommon for such matters to be resolved over many years, during which time relevant developments and new information is continuously evaluated to determine both the likelihood of any potential loss and whether it is possible to reasonably estimate a range of possible losses. When a loss is probable but a reasonable estimate cannot be made, disclosure is provided.

Refer note 34 for details on contingent liabilities.

Business combinations

Determination of whether a set of assets acquired and liabilities assumed constitute the acquisition of a business or asset may require the Group to make certain judgements as to whether or not the assets acquired and liabilities assumed include the inputs, processes and outputs necessary to constitute a business as defined in IFRS 3 Business Combinations. Based on an assessment of the relevant facts and circumstances, the Group concluded that the acquisition of the Gruyere Gold Project (refer note 15.2 for details of the acquisition) did not meet the criteria for accounting as a business combination and the transaction was accounted for as an acquisition of an asset at 31 December 2016.

CONSOLIDATION

2. CONSOLIDATION

2.1 Business combinations

The acquisition method of accounting is used to account for business combinations by the Group. The consideration transferred for the acquisition of a business is the fair value of the assets transferred, the liabilities incurred and the equity interests issued by the Group. The consideration transferred includes the fair value of any asset or liability resulting from a contingent consideration arrangement. Acquisition-related costs are expensed as incurred, other than those associated with the issue of debt or equity securities. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. On an acquisition-by-acquisition basis, the Group recognises any non-controlling interest in the acquiree either at fair value or at the non-controlling interest’s proportionate share of the acquiree’s net assets. Subsequently, the carrying amount of non-controlling interest is the amount of the interest at initial recognition plus the non-controlling interest’s share of the subsequent changes in equity.

The excess of the consideration transferred, the amount of any non-controlling interest in the acquiree and the acquisition date fair value of any previous equity interest in the acquiree over the fair value of the identifiable net assets acquired is recorded as goodwill. If this is less than the fair value of the net assets of the subsidiary acquired in the case of a bargain purchase, the difference is recognised directly in profit or loss.

If a transaction does not meet the definition of a business under IFRS, the transaction is recorded as an asset acquisition. Accordingly, the identifiable assets acquired and liabilities assumed are measured at the fair value of the consideration paid, based on their relative fair values at the acquisition date. Acquisition-related costs are included in the consideration paid and capitalised. Any contingent consideration payable that is dependent on the purchaser’s future activity is not included in the consideration paid until the activity requiring the payment is performed. Any resulting future amounts payable are recognised in profit or loss when incurred. No goodwill and no deferred tax asset or liability arising from the assets acquired and liabilities assumed are recognised upon the acquisition of assets.

2.2 Subsidiaries

Subsidiaries are all entities controlled by the Group. The Group controls an entity when it is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the relevant activities of the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Group until the date on which control ceases.

Inter-company transactions, balances and unrealised gains and losses on transactions between Group companies are eliminated. Accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the Group.

2.3 Transactions with non-controlling interests

The Group treats transactions with non-controlling interests that do not result in loss of control as transactions with equity owners of the Group. For purchases from non-controlling interests, the difference between any consideration paid and the relevant share acquired of the carrying value of net assets of the subsidiary is recorded in equity. Gains or losses on disposals to non-controlling interests are also recorded in equity.

2.4 Equity accounted investees

The Group’s interests in equity accounted investees comprise interests in associates and joint ventures.

Associates are those entities in which the Group has significant influence, but not control or joint control, over the financial and operating policies. Joint ventures are arrangements in which the Group has joint control, whereby the Group has rights to the net assets of the arrangement, rather than rights to its assets and obligations for its liabilities.

Interests in associates and joint ventures are accounted for using the equity method. They are recognised initially at cost, which includes transaction costs. Subsequent to initial recognition, the consolidated financial statements include the Group’s share of the profit or loss and the other comprehensive income of equity accounted investees, until the date on which significant influence or joint control ceases.

Results of associates and joint ventures are equity accounted using the results of their most recent audited financial statements. Any losses from associates or joint ventures are brought to account in the consolidated financial statements until the interest in such associates or joint ventures is written down to zero. Thereafter, losses are accounted for only insofar as the Group is committed to providing financial support to such associates or joint ventures.

The carrying value of an investment in associate and joint ventures represents the cost of the investment, including goodwill, a share of the post-acquisition retained earnings and losses, any other movements in reserves and any accumulated impairment losses. The carrying value is assessed annually for existence of indicators of impairment and if such exist, the carrying amount is compared to the recoverable amount, being the higher of value in use or fair value less cost of disposal. If an impairment in value has occurred it is recognised in profit or loss in the period in which the impairment arose.

2.5 Joint operations

A joint operation is a joint arrangement whereby the parties that have joint control of the arrangement have rights to the use of assets and obligations for the liabilities of the arrangement. The Group accounts for activities under joint operations by recognising in relation to the joint operation, the assets it controls and the liabilities it incurs, the expenses it incurs and the revenue from the sale or use of its share of the joint operations output.

FOREIGN CURRENCIES

3. FOREIGN CURRENCIES

3.1 Functional and presentation currency

Items included in the financial statements of each of the Group entities are measured using the currency of the primary economic environment in which the entity operates (“the functional currency”). The consolidated financial statements are presented in US Dollar.

3.2 Transactions and balances

Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions, and from the translation of monetary assets and liabilities denominated in foreign currencies, are recognised in profit or loss. Translation differences on available-for-sale equities are included in other comprehensive income.

3.3 Foreign operations

The results and financial position of all the Group entities (none of which has the currency of a hyperinflationary economy) that have a functional currency different from the presentation currency are translated into the presentation currency as follows:

Assets and liabilities are translated at the exchange rate ruling at the reporting date (ZAR/US$: 12.58; US$/A$: 0.77 (2016: ZAR/US$: 14.03; US$/A$: 0.72 and 2015: ZAR/US$: 15.10; US$/A$: 0.73)). Equity items are translated at historical rates. The income and expenses are translated at the average exchange rate for the year (ZAR/US$: 13.33; US$/A$: 0.77 (2016: ZAR/US$: 14.70; US$/A$: 0.75 and 2015: ZAR/US$: 12.68; US$/A$: 0.75)), unless this average was not a reasonable approximation of the rates prevailing on the transaction dates, in which case these items were translated at the rate prevailing on the date of the transaction. Exchange differences on translation are accounted for in other comprehensive income. These differences will be recognised in profit or loss upon realisation of the underlying operation.

On consolidation, exchange differences arising from the translation of the net investment in foreign operations (i.e. the reporting entity’s interest in the net assets of that operation), and of borrowings and other currency instruments designated as hedges of such investments, are taken to other comprehensive income. When a foreign operation is sold, exchange differences that were recorded in other comprehensive income are recognised in profit or loss as part of the gain or loss on disposal. If the Group disposes of part of its interest in a subsidiary but retains control, then the relevant proportion of the cumulative amount is reattributed to non-controlling interests. When the Group disposes of only part of an associate or joint venture while retaining significant influence or joint control, the relevant proportion of the cumulative amount is reclassified to profit or loss.

Goodwill and fair value adjustments arising on the acquisition of a foreign operation are treated as assets and liabilities of the foreign operation and are translated at each reporting date at the closing rate.

PROPERTY, PLANT AND EQUIPMENT

4. PROPERTY, PLANT AND EQUIPMENT

4.1 Mine development and infrastructure

Mining assets, including mine development and infrastructure costs and mine plant facilities, are recorded at cost less accumulated depreciation and accumulated impairment losses.

Expenditure incurred to evaluate and develop new orebodies, to define mineralisation in existing orebodies and to establish or expand productive capacity, is capitalised until commercial levels of production are achieved, at which times the costs are amortised as set out below.

Development of orebodies includes the development of shaft systems and waste rock removal that allows access to reserves that are economically recoverable in the future. Subsequent to this, costs are capitalised if the criteria for recognition as an asset are met.

4.2 Borrowing costs

Borrowing costs incurred in respect of assets requiring a substantial period of time to prepare for their intended future use are capitalised to the date that the assets are substantially completed.

4.3 Mineral and surface rights

Mineral and surface rights are recorded at cost less accumulated amortisation and accumulated impairment losses. When there is little likelihood of a mineral right being exploited, or the fair value of mineral rights has diminished below cost, an impairment loss is recognised in profit or loss in the year that such determination is made.

4.4 Land

Land is shown at cost and is not depreciated.

4.5 Other assets

Non-mining assets are recorded at cost less accumulated depreciation and accumulated impairment losses. These assets include the assets of the mining operations not included in mine development and infrastructure, borrowing costs, mineral and surface rights and land and all the assets of the non-mining operations.

4.6 Amortisation and depreciation of mining assets

Amortisation and depreciation is determined to give a fair and systematic charge to profit or loss taking into account the nature of a particular ore body and the method of mining that ore body. To achieve this, the following calculation methods are used:

• Mining assets, including mine development and infrastructure costs, mine plant facilities and evaluation costs, are amortised over the life of the mine using the units-of-production method, based on estimated proved and probable ore reserves;

• Stripping activity assets are amortised on a units-of-production method, based on the estimated proved and probable ore reserves of the ore body to which the assets relate; and

• The mineral rights asset at the Australian operations are divided at the respective operations into a depreciable and a non-depreciable component. The mineral rights asset is initially capitalised to the mineral rights asset as a non-depreciable component.

Subsequently, and on an annual basis, as part of the preparation of the updated reserve and resource statement and preparation of the updated life-of-mine plan, a portion of resources will typically be converted to reserves as a result of ongoing resource definition drilling, resultant geological model updates and subsequent mine planning. Based on this conversion of resources to reserves a portion of the historic cost is allocated from the non-depreciable component of the mineral rights asset to the depreciable component of the mineral rights asset. Therefore, the category of non-depreciable mineral rights asset is expected to reduce and will eventually be fully allocated within the depreciable component of the mineral rights asset.

Each operation typically comprises a number of mines and the depreciable component of the mineral rights asset is therefore allocated on a mine-by-mine basis at the operation and is transferred at this point to mine development and infrastructure and is then amortised over the estimated proved and probable ore reserves of the respective mine on the units-of-production method. The remaining non-depreciable component of the mineral rights asset is not amortised but, in combination with the depreciable component of the mineral rights asset and other assets included in the CGU, is evaluated for impairment when events and changes in circumstances indicate that the carrying amount may not be recoverable.

Proved and probable ore reserves reflect estimated quantities of economically recoverable reserves, which can be recovered in future from known mineral deposits.

Certain mining plant and equipment included in mine development and infrastructure is depreciated on a straight-line basis over the lesser of their estimated useful lives or life-of-mine.

Correction of amortisation for Australian mineral rights asset

During the year ended 31 December 2017, the Group corrected the amortisation methodology for the mineral rights asset at the Australian operations to reduce the level of estimation uncertainty required in calculating amortisation. Prior to the correction of methodology, the total mineral rights asset capitalised at the Australian operations was amortised on a units-of-production basis over a useful life that exceeded proved and probable reserves. The revised amortisation methodology for the mineral rights assets is set out on page 144.

At 1 January 2017, as a result of this correction of methodology, management identified an understatement of the amortisation and depreciation charge in prior periods. The understatement has been corrected by restating each of the affected financial statement line items for prior periods (refer note 40 for further details).

The impact of the correction of the amortisation methodology resulted in an increase in amortisation of US$5.7 million for the 2017 year.

4.7 Depreciation of non-mining assets

Non-mining assets are recorded at cost and depreciated on a straight-line basis over their current expected useful lives to their residual values as follows:

• Vehicles – 20%

• Computers – 33.3%

• Furniture and equipment – 10%

The assets’ useful lives, depreciation methods and residual values are reassessed at each reporting date and adjusted if appropriate.

4.8 Mining exploration

Expenditure on advances solely for exploration activities is charged against profit or loss until the viability of the mining venture has been proven. Expenditure incurred on exploration “farm-in” projects is written off until an ownership interest has vested. Exploration expenditure to define mineralisation at existing ore bodies is considered mine development costs and is capitalised until commercial levels of production are achieved.

Exploration activities at certain of the Group’s non-South African operations are broken down into defined areas within the mining lease boundaries. These areas are generally defined by structural and geological continuity. Exploration costs in these areas are capitalised to the extent that specific exploration programmes have yielded targets and/or results that warrant further exploration in future years.

4.9 Impairment

Recoverability of the carrying values of long-term assets or CGUs of the Group are reviewed annually or whenever events or changes in circumstances indicate that such carrying values may not be recoverable. To determine whether a long-term asset or CGU may be impaired, the higher of “value in use” (defined as: “the present value of future cash flows expected to be derived from an asset or CGU”) or “fair value less costs of disposal” (defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date”) is compared to the carrying value of the asset/CGU. Impairment losses are recognised in profit or loss.

A CGU is defined by the Group as the smallest identifiable group of assets that generates cash inflows that are largely independent of the cash inflows from other assets or groups of assets. Generally for the Group this represents an individual operating mine, including mines which are part of a larger mine complex. The costs attributable to individual shafts of a mine are impaired if the shaft is closed.

Exploration targets in respect of which costs have been capitalised at certain of the Group’s international operations are evaluated on an annual basis to ensure that these targets continue to support capitalisation of the underlying costs. Those that do not are impaired.

When any infrastructure is closed down during the year, any carrying value attributable to that infrastructure is impaired.

4.10 Gain or loss on disposal of property, plant and equipment

Any gain or loss on disposal of property, plant and equipment (calculated as the net proceeds from disposal less the carrying amount of the item) is recognised in profit or loss.

4.11 Leases

At the inception of an arrangement, the Group determines whether the arrangement contains a lease. Leases that transfer to the Group substantially all of the risks and rewards of ownership are classified as finance leases. All other leases are classified as operating leases and are not recognised in the statement of financial position.

Operating lease costs are charged against profit or loss on a straight-line basis over the period of the lease.

4.12 Deferred stripping

Production stripping costs in a surface mine are capitalised to property, plant and equipment if, and only if, all of the following criteria are met:

• It is probable that the future economic benefit associated with the stripping activity will flow to the entity;

• The entity can identify the component of the ore body for which access has been improved; and

• The costs relating to the stripping activity associated with that component can be measured reliably.

If the above criteria are not met, the stripping costs are recognised directly in profit or loss.

The Group initially measures the stripping activity asset at cost, this being the accumulation of costs directly incurred to perform the stripping activity that improves access to the identified component of ore.

After initial recognition, the stripping activity asset is carried at cost less accumulated amortisation and accumulated impairment losses.

GOODWILL

5. GOODWILL

Goodwill is stated at cost less accumulated impairment losses. Goodwill on acquisition of equity accounted investees is tested for impairment as part of the carrying amount of the investment in associate or joint venture whenever there is any objective evidence that the investment may be impaired. Goodwill on acquisition of a subsidiary is assessed annually or whenever there are impairment indicators to establish whether there is any indication of impairment to goodwill. A write-down is made if the carrying amount exceeds the recoverable amount. Impairment losses on goodwill are not reversed. Gains and losses on the disposal of an entity include the carrying amount of goodwill allocated to the entity sold.

Goodwill is allocated to CGUs for the purpose of impairment testing. The allocation is made to those CGUs or groups of CGUs that are expected to benefit from the business combination in which the goodwill arose.

TAXATION

6. TAXATION

Income tax comprises current and deferred tax. Current tax and deferred tax is recognised in profit or loss except to the extent that it relates to a business combination, or items recognised directly in equity or in other comprehensive income.

Current tax is measured on taxable income at the applicable statutory rate substantively enacted at the reporting date.

Deferred taxation is provided on temporary differences existing at each reporting date between the tax values of assets and liabilities and their carrying amounts. Substantively enacted tax rates are used to determine future anticipated effective tax rates which in turn are used in the determination of deferred taxation.

Deferred taxation is not recognised for temporary differences on the initial recognition of assets or liabilities in a transaction that is not a business combination and that affects neither accounting nor taxable profit or loss and taxable temporary differences arising on the initial recognition of goodwill.

The measurement of deferred tax reflects the tax consequences that would follow the manner in which the Group expects, at the end of the reporting period, to recover or settle the carrying amount of its assets and liabilities.

These temporary differences are expected to result in taxable or deductible amounts in determining taxable profits for future periods when the carrying amount of the asset is recovered or the liability is settled.

Deferred tax liabilities are generally recognised for all taxable temporary differences. Deferred tax liabilities are recognised for taxable temporary differences arising on investments in subsidiaries and equity accounted investees except where the reversal of the temporary difference can be controlled and it is probable that the difference will not reverse in the foreseeable future.

Deferred tax assets relating to the carry forward of unutilised tax losses and/or deductible temporary differences are recognised to the extent it is probable that future taxable profit will be available against which the unutilised tax losses and/or deductible temporary differences can be recovered. Deferred tax assets are reviewed at each reporting date and are adjusted if recovery is no longer probable.

Deferred tax assets and liabilities are offset if there is a legally enforceable right to offset current tax liabilities and assets, and they relate to taxes levied by the same tax authority on the same taxable entity, or on different tax entities, but they intend to settle current tax liabilities and assets on a net basis or their tax assets and liabilities will be realised simultaneously.

Except for Tarkwa, no provision is made for any potential taxation liability on the distribution of retained earnings by Group companies as it is probable that the related taxable temporary differences will not reverse in the foreseeable future.

INVENTORIES

7. INVENTORIES

Inventories are valued at the lower of cost and net realisable value. Gold on hand represents production on hand after the smelting process.

Cost is determined on the following basis:

• Gold on hand and gold-in-process is valued using weighted average cost. Cost includes production, amortisation and related administration costs;

• Heap leach and stockpiles inventories are valued using weighted average cost. Cost includes production, amortisation and related administration costs. The cost of materials on the heap leach and stockpiles from which metals are expected to be recovered in a period longer than 12 months is classified as non-current assets; and

• Consumable stores are valued at weighted average cost, after appropriate provision for redundant and slow-moving items.

Net realisable value is determined with reference to relevant market prices or the estimated future sales price of the product if it is expected to be realised in the long term.

FINANCIAL INSTRUMENTS

8. FINANCIAL INSTRUMENTS

8.1 Non-derivative financial assets and liabilities

The Group classifies non-derivative financial assets into the following categories: financial assets at fair value through profit or loss, loans and receivables and available-for-sale financial assets.

The Group classifies non-derivative financial liabilities into the other financial liabilities category.

The Group initially recognises loans and receivables on the date they are originated. All other financial assets (including assets designated at fair value through profit or loss) are recognised initially on trade date, which is the date that the Group becomes a party to the contractual provisions of the instrument. The Group derecognises a financial asset when the contractual rights to the cash flows in a transaction in which substantially all the risks and rewards of the ownership of the financial asset are transferred. The Group derecognises a financial liability when its contractual obligations are discharged, cancelled or expire. Any interest in such transferred financial asset that is created or retained by the Group is recognised as a separate asset or liability. The particular recognition and measurement methods adopted are disclosed in the individual policy statements associated with each item.

A financial asset not classified as fair value through profit or loss is assessed at each reporting date to determine whether there is objective evidence that it is impaired. A financial asset is impaired if there is objective evidence of impairment as a result of one or more events that occurred after the initial recognition of the asset and the loss event(s) had an impact on the estimated future cash flows of that asset that can be estimated reliably. Objective evidence that financial assets are impaired includes default or delinquency by a debtor, indications that a debtor will enter bankruptcy, economic conditions that correlate with defaults or the disappearance of an active market for a security.

An impairment loss in respect of a financial asset measured at amortised cost is calculated as the difference between its carrying amount and the present value of the estimated future cash flows discounted at the asset’s original effective interest rate. Losses are recognised in profit or loss and reflected in an allowance against loans and receivables. When an event occurring after the impairment loss was recognised causes the amount of impairment loss to decrease, the decrease in impairment loss is reversed through profit or loss. A significant or prolonged decline in the fair value of an available-for-sale financial asset below its cost is objective evidence of impairment. Impairment losses on available-for-sale financial assets are recognised by reclassifying the losses accumulated in the fair value adjustment reserve in other comprehensive income to profit or loss. Impairment losses charged to profit or loss on available-for-sale financial assets are not reversed.

Financial assets and financial liabilities are offset and the net amount presented in the statement of financial position when, and only when, the Group has a currently legally enforceable right to offset the amounts and intends to settle them on a net basis or to realise the asset and settle the liability simultaneously.

8.1.1 Investments

Investments comprise (1) investments in listed companies which are classified as available-for-sale and are accounted for at fair value, with unrealised gains and losses subsequent to initial recognition recognised in other comprehensive income and included in other reserves, and released to profit or loss when the investments are sold or impaired; and (2) investments in unlisted companies which are accounted for at cost and adjusted for impairment where appropriate.

Purchases and sales of investments are recognised on the trade date, which is the date that the Group commits to purchase or sell the asset. Cost of purchase includes transaction costs. The fair value of listed investments is based on quoted bid prices.

On disposal or impairment of available-for-sale financial assets, cumulative unrealised gains and losses previously recognised in other comprehensive income are included in determining the profit or loss on disposal, or the impairment charge relating to, that financial asset, respectively, which is recognised in profit or loss.

8.1.2 Cash and cash equivalents

Cash and cash equivalents comprise cash on hand, demand deposits and short-term, highly liquid investments readily convertible to known amounts of cash and subject to insignificant risk of changes in value and are measured at amortised cost which is deemed to be fair value as they have a short-term maturity.

Bank overdrafts are included within current liabilities in the statement of financial position and within cash and cash equivalents in the statement of cash flows.

8.1.3 Trade receivables

Trade receivables are initially recognised at fair value and subsequently carried at amortised cost less allowance for impairment, except for trade receivables from provisional copper and gold concentrate sales. Estimates made for impairment are based on a review of all outstanding amounts at year-end. Irrecoverable amounts are written off during the year in which they are identified.

The trade receivables from provisional copper and gold concentrate sales are carried at fair value through profit or loss and are marked-to-market at the end of each period until final settlement occurs, with changes in fair value classified as provisional price adjustments and included as a component of revenue.

8.1.4 Trade payables

Trade payables are recognised initially at fair value and subsequently measured at amortised cost using the effective interest method.

8.1.5 Borrowings

Borrowings are recognised initially at fair value, net of transaction costs incurred, where applicable and subsequently measured at amortised cost using the effective interest method.

Borrowings are classified as current liabilities unless the Group has an unconditional right to defer settlement of the liability for at least 12 months after the reporting date.

Interest payable on borrowings is recognised in profit or loss over the term of the borrowings using the effective interest method.

Finance expense comprises interest on borrowings and environmental rehabilitation costs offset by interest capitalised on qualifying assets.

Cash flows from interest paid are classified under operating activities in the statement of cash flows.

8.2 Derivative financial instruments

The Group’s general policy with regards to its exposure to the dollar gold price is to remain unhedged. The Group may from time to time establish currency and/or interest rate and/or commodity financial instruments to protect underlying cash flows.

On the date a derivative contract is entered into, the Group designates the derivative as (1) a hedge of the fair value of a recognised asset or liability (fair value hedge), (2) a hedge of a forecast transaction or a firm commitment (cash flow hedge), (3) a hedge of a net investment in a foreign entity, or (4) should the derivative not fall into one of the three categories above it is not regarded as a hedge.

Derivative financial instruments are initially recognised in the statement of financial position at fair value and subsequently remeasured at their fair value, unless they meet the criteria for the normal purchases normal sales exemption.

Provided the Group’s derivative transactions do not qualify for hedge accounting, changes in the fair value of such derivatives are recognised immediately in profit or loss.

8.3 Embedded derivatives

The Group assesses whether an embedded derivative is required to be separated from a host contract and accounted for as a derivative when the Group first becomes a party to a contract.

Embedded derivatives are separated from the host contract and accounted for separately if:

• The economic characteristics and risks of the host contract and the embedded derivative are not closely related;

• A separate instrument with the same terms as the embedded derivative would meet the definition of a derivative; and

• The combined instrument is not measured at fair value through profit or loss.

Subsequent reassessment is not performed unless there is a change in the terms of the contract that significantly modifies the cash flows.

PROVISIONS

9. PROVISIONS

Provisions are recognised when the Group has a present legal or constructive obligation resulting from past events and it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation.

PROVISION FOR ENVIRONMENTAL REHABILITATION COSTS

10. PROVISION FOR ENVIRONMENTAL REHABILITATION COSTS

Long-term provisions for environmental rehabilitation costs are based on the Group’s environmental management plans, in compliance with applicable environmental and regulatory requirements.

Rehabilitation work can include facility decommissioning and dismantling, removal or treatment of waste materials, site and land rehabilitation, including compliance with and monitoring of environmental regulations, security and other site-related costs required to perform the rehabilitation work and operations of equipment designed to reduce or eliminate environmental effects.

Full provision is made based on the net present value of the estimated cost of restoring the environmental disturbance that has occurred up to the reporting date. The unwinding of the obligation is accounted for in profit or loss.

The estimated costs of rehabilitation are reviewed annually and adjusted as appropriate for changes in legislation, technology or other circumstances. Cost estimates are not reduced by the potential proceeds from the sale of assets or from plant clean up at closure.

Changes in estimates are capitalised or reversed against the relevant asset, except where a reduction in the provision is greater than the remaining net book value of the related asset, in which case the value is reduced to nil and the remaining adjustment is recognised in profit or loss. In the case of closed sites, changes in estimates and assumptions are recognised in profit or loss. Estimates are discounted at the risk-free rate in the jurisdiction of the obligation.

Increases due to additional environmental disturbances are capitalised and amortised over the remaining lives of the mines. These increases are accounted for on a net present value basis.

For the South African and Ghanaian operations, annual contributions are made to a dedicated rehabilitation trust fund and dedicated bank account, respectively, to fund the estimated cost of rehabilitation during and at the end of the life-of-mine. The amounts contributed to this trust fund/bank account are included under non-current assets. Interest earned on monies paid to rehabilitation trust fund/bank account is accrued on a time proportion basis and is recorded as interest income.

In respect of the South African, Ghanaian and Peruvian operations, bank and other guarantees are provided for funding of the environmental rehabilitation obligations.

EMPLOYEE BENEFITS

11. EMPLOYEE BENEFITS

11.1 Short-term employee benefits

Short-term employee benefits are expensed as the related service is provided. A liability is recognised for the amount expected to be paid if the Group has a present legal or constructive obligation to pay this amount as a result of past service provided by the employee and the obligation can be estimated reliably.

11.2 Pension and provident funds

The Group operates a defined contribution retirement plan and contributes to a number of industry-based defined contribution retirement plans. The retirement plans are funded by payments from employees and Group companies.

Contributions to defined contribution funds are recognised as an employee benefit expense in profit or loss in the periods during which related services are rendered by employees.

11.3 Share-based payments

The Group operates a number of equity-settled compensation plans. The fair value of the equity-settled instruments is measured by reference to the fair value of the equity instrument granted which in turn is determined using the Black-Scholes and Monte Carlo simulation models on the date of grant.

Fair value is based on market prices of the equity-settled instruments granted, if available, taking into account the terms and conditions upon which those equity-settled instruments were granted. Fair value of equity-settled instruments granted is estimated using appropriate valuation models and appropriate assumptions at grant date. Non-market vesting conditions (service period prior to vesting) are not taken into account when estimating the fair value of the equity-settled instruments at grant date. Market conditions are taken into account in determining the fair value at grant date.

The fair value of the equity-settled instruments is recognised as an employee benefit expense over the vesting period based on the Group’s estimate of the number of instruments that will eventually vest, with a corresponding increase in equity. Vesting assumptions for non-market conditions are reviewed at each reporting date to ensure they reflect current expectations.

Where the terms of an equity-settled award are modified, the originally determined expense is recognised as if the terms had not been modified. In addition, an expense is recognised for any modification, which increases the total fair value of the share-based payment arrangement, or is otherwise beneficial to the participant as measured at the date of the modification.

11.4 Long-term incentive plan

The Group operates a long-term incentive plan.

The Group’s net obligation in respect of the long-term incentive plan is the amount of future benefit that employees have earned in return for their services in the current and prior periods. That benefit is estimated using appropriate assumptions and is discounted to determine its present value at each reporting date. Re-measurements are recognised in profit or loss in the period in which they arise.

11.5 Termination benefits

Termination benefits are payable when employment is terminated by the Group before the normal retirement date, or whenever an employee accepts voluntary redundancy in exchange for these benefits. Termination benefits are expensed at the earlier of the date the Group can no longer withdraw the offer of those benefits or the date the Group recognises costs for a restructuring. Benefits falling due more than 12 months after the reporting date are discounted to present value.

SHARE CAPITAL

12. SHARE CAPITAL

12.1 Ordinary share capital

Ordinary shares are classified as equity. Incremental costs directly attributable to the issue of ordinary shares are recognised as a deduction from equity, net of any tax effects.

12.2 Repurchase and reissue of share capital

When share capital recognised as equity is repurchased, the amount of the consideration paid, which includes directly attributable costs, net of any tax effects, is recognised as a deduction from equity. Repurchased shares are classified as treasury shares and are deducted from equity. When treasury shares are sold or reissued subsequently, the amount received is recognised as an increase in equity, and the resulting surplus or deficit on the transaction is presented in share premium.

REVENUE RECOGNITION

13. REVENUE RECOGNITION

Revenue is recognised to the extent that it is probable that economic benefits will flow to the Group and the amount of revenue can be reliably measured. Revenue is stated at the fair value of the consideration received or receivable.

Revenue arising from gold, copper and silver sales is recognised when the significant risks and rewards of ownership pass to the buyer. The price of gold, copper and silver is determined by market forces.

Copper and gold concentrate revenue is calculated, net of refining and treatment charges, on a best estimate basis on shipment date, using forward metal prices to the estimated final pricing date, adjusted for the specific terms of the agreements. Variations between the price recorded at the shipment date and the actual final price received are caused by changes in prevailing copper and gold prices, and result in an embedded derivative in the trade receivable. The embedded derivative is marked-to-market each period until final settlement occurs, with changes in fair value classified as provisional price adjustments and included as a component of revenue.

INVESTMENT INCOME

14. INVESTMENT INCOME

Investment income comprises interest income on funds invested and dividend income from listed and unlisted investments.

Investment income is recognised to the extent that it is probable that economic benefits will flow to the Group and the amount of investment income can be reliably measured. Investment income is stated at the fair value of the consideration received or receivable.

14.1 Dividends, which include capitalisation dividends, are recognised when the right to receive payment is established.

14.2 Interest income is recognised on a time proportion basis taking account the principal outstanding and the effective rate over the period to maturity.

Cash flows from dividends and interest received are classified under operating activities in the statement of cash flows.

DIVIDENDS DECLARED

15. DIVIDENDS DECLARED

Dividends and the related taxation thereon are recognised only when such dividends are declared.

Dividends withholding tax is a tax on shareholders receiving dividends and is applicable to all dividends paid. The Group withholds dividends tax on behalf of its shareholders at a rate of 20% on dividends paid. Amounts withheld are not recognised as part of the Group’s tax charge but rather as part of the dividend paid recognised directly in equity.

Cash flows from dividends paid are classified under operating activities in the statement of cash flows.

EARNINGS PER SHARE

16. EARNINGS PER SHARE

The Group presents basic and diluted earnings per share. Basic earnings per share is calculated based on the profit attributable to ordinary shareholders divided by the weighted average number of ordinary shares in issue during the period. Diluted earnings per share is determined by adjusting the profit attributable to ordinary shareholders, if applicable, and the weighted average number of ordinary shares in issue for ordinary shares that may be issued in the future

NON-CURRENT ASSETS HELD FOR SALE

17. NON-CURRENT ASSETS HELD FOR SALE

Non-current assets (or disposal groups) comprising assets and liabilities, are classified as held for sale if it is highly probable they will be recovered primarily through sale rather than through continuing use. These assets may be a component of an entity, a disposal group or an individual non-current asset.

Non-current assets held for sale are stated at the lower of carrying amount and fair value less costs to sell. Once classified as held for sale or distribution, property, plant and equipment is no longer amortised or depreciated.

DISCONTINUED OPERATIONS

18. DISCONTINUED OPERATIONS

A discontinued operation is a component of the Group’s business, the operations and cash flows of which can be clearly distinguished from the rest of the Group and which:

• Represents a separate major line of business or geographic area of operations;

• Is part of a single co-ordinated plan to dispose of a separate major line of business or geographic area of operations; or

• Is a subsidiary acquired exclusively with a view to re-sale.

Classification as a discontinued operation occurs at the earlier of disposal or when the operation meets the criteria to be classified as held-for-sale, if earlier.

When an operation is classified as a discontinued operation, the comparative income statement and statement of cash flows are re-presented as if the operation had been discontinued from the start of the comparative period.

SEGMENTAL REPORTING

19. SEGMENTAL REPORTING

Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker and is based on individual mining operations. The chief operating decision-maker, who is responsible for allocating resources and assessing performance of the operating segments, has been identified as the Executive Committee that makes strategic decisions.

HEADLINE EARNINGS

20. HEADLINE EARNINGS

Headline earnings is an additional earnings number that is permitted by IAS 33 Earnings per Share (“IAS 33”) as set out in the SAICA Circular 2/2015 (Circular). The starting point is earnings as determined in IAS 33, excluding separately identifiable remeasurements net of related tax (both current and deferred) and related non-controlling interest, other than re-measurements specifically included in headline earnings. A remeasurement is an amount recognised in profit or loss relating to any change (whether realised or unrealised) in the carrying amount of an asset or liability that arose after the initial recognition of such asset or liability. Included remeasurement items are included in Section C of the Circular.

Summary of Standards, Interpretations and Amendments to Published Standards Effective

Standards, interpretations and amendments to published standards effective for the year ended 31 December 2017

During the financial year, the following new and revised accounting standards, amendments to standards and new interpretations were adopted by the Group:

Standard(s) Amendment(s) Interpretation(s)	Nature of the Change	Salient features of the changes	Impact on financial position or performance
IAS 7 Statement of cash flows	Amendments	•  The amendments require disclosures that enable users of financial statements to evaluate changes in liabilities arising from financing activities, including both changes arising from cash flow and non-cash changes.	No impact
IAS 12 Income taxes	Amendments	•  The amendments provide additional guidance on the existence of deductible temporary differences; and •  The amendments also provide additional guidance on the methods used to calculate future taxable profit to establish whether a deferred tax asset can be recognised.	No impact

Summary of Standards, Interpretations and Amendments to Published Standards Which Are Not Yet Effective

Standards, interpretations and amendments to published standards which are not yet effective

Certain new standards, amendments and interpretations to existing standards have been published that apply to the Group’s accounting periods beginning on 1 January 2018 or later periods but have not been early adopted by the Group.

These standards, amendments and interpretations that are relevant to the Group are:

Standard(s) Amendment(s) Interpretation(s)	Nature of the Change		Salient features of the changes	Effective date*
IFRS 2 Share-based payments		Amendments	•  The amendments cover three accounting areas: -  Measurement of cash-settled share-based payments; -  Classification of share-based payments settled net of tax withholdings; and -  Accounting for a modification of a share-based payment from cash-settled to equity-settled. •  The amendment does not have a material impact on the Group.		1 January 2018
IFRS 9 Financial Instruments		New standard	•  This IFRS sets out requirements for recognising and measuring financial assets, financial liabilities and some contracts to buy or sell non-financial items. This standard replaces IAS 39 Financial Instruments. The Group will adopt IFRS 9 on 1 January 2018; •  This IFRS contains a new classification and measurement approach for financial assets that reflects the business model in which the assets are managed and their cash flow characteristics. The three principal		1 January 2018
			classification categories for financial assets are: measured at amortised cost, fair value through profit or loss (“FVTPL”) and fair value through other comprehensive income (“FVOCI”); •  Based on the Group’s assessment, the Group believes that the new classification if applied at 31 December 2017, would not have a significant impact on its accounting for financial assets. The Group’s available-for-sale financial assets will be designated at FVOCI; and •  The new measurement principles will not have a material impact on the Group.
IFRS 15 Revenue from contracts with customers		New standard	•  This IFRS introduces a new revenue recognition model for contracts with customers and establishes a comprehensive framework for determining whether, how much and when revenue is recognised. IFRS 15 also includes extensive new disclosure requirements; •  The Group has assessed the impact of adopting IFRS 15 and has determined the impact as follows: •  Revenue will be recognised when the customer takes control of the gold, copper and silver. The timing of recognition of revenue will no longer be when risks and rewards of ownership pass to the customer; •  The change in timing of revenue recognition will result in revenue at the South African and Australian operations being recognised on settlement date (date when control passes) and not contract date (previous date when risks and rewards of ownership pass). There is no change to the revenue recognition at any of the other operations given that the date of control is the same date as when risks and rewards of ownership pass. The change in timing of revenue recognition for the South African and Australian operations will be that revenue will be recognised approximately two days later than it currently is recognised. As approximately 0.3% of 2017 revenue will		1 January 2018
			now be recognised in 2018, the adoption of IFRS 15 will not have a material impact on the revenue of the Group; and •  The Group will adopt IFRS 15 using the cumulative effect method, with the effect of initially applying this standard at the date of initial application (i.e. 1 January 2018). As a result, the Group will not apply the requirements of IFRS 15 to the comparative periods presented.
IFRS 16 Leases		New standard	•  This IFRS sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract, i.e. the customer (‘lessee’) and the supplier (‘lessor’); •  IFRS 16 replaces the previous leases Standard, IAS 17 Leases, and related Interpretations; •  IFRS 16 has one model for lessees which will result in almost all leases being included on the statement of financial position. No significant changes have been included for lessors; and •  Management has commenced compiling a list of all potential leases and is in the process of reviewing all such contracts in order to assess the impact the standard will have on the Group.	1 January 2019
IFRIC 23 Uncertainty over Income Tax Treatments		New interpretation	•  This interpretation clarifies the accounting for income tax treatments that have yet to be accepted by tax authorities; •  IFRIC 23 specifically clarifies how to incorporate this uncertainty into the measurement of tax as reported in the financial statements; •  IFRIC 23 does not introduce any new disclosures but reinforces the need to comply with existing disclosure requirements about judgements made, assumptions and other estimates used and the potential impact of uncertainties that are not reflected •  The interpretation will not have a material impact on the Group.	1 January 2019

* Effective date refers to annual period beginning on or after said date.

1 Due to the availability of unredeemed capital for tax purposes over several years into the life of the South Deep mine, nominal cash flows are used for South Africa. In order to determine nominal cash flows in South Africa, costs are inflated by the current South African inflation rate. Cash flows for all other operations are in real terms and as a result are not inflated.

1 Refer note 40 for further details.

2 The methodology for amortisation and depreciation at Cerro Corona was amended in 2017, changing to gold ounces produced from tonnes mined. Gold ounces are considered a better reflection of the pattern in which the mine’s future economic benefits are expected to be consumed by the mine in line with the declining grade over the life-of-mine.

2 The impact of the change in useful life at Cerro Corona resulted in an increase in amortisation and depreciation of US$24.5 million for the 2017 year.

2 The methodology for amortisation of the mineral rights asset at the Australian operations was corrected during the year. Refer note 40 for further details.

2 The impact of the correction of the amortisation methodology at the Australian operations resulted in an increase in amortisation of US$5.7 million for the 2017 year.

2 Given the nature of the inputs used to calculate the amortisation and depreciation, namely future production as well as proven and probable reserves, it is not practicable to estimate the future impact the change in useful life and correction in methodology will have on amortisation and depreciation.

1 Following the identification of impairment indicators at 30 June 2015, the investment in Hummingbird was valued at its recoverable amount, which resulted in an impairment of US$7.5 million. The recoverable amount was based on the investment’s fair value at the time, being its quoted market price (level 1 of the fair value hierarchy). The impairment is included in the “Corporate and other” segment.

2 Following the identification of impairment indicators at 31 December 2015, FSE was valued at its recoverable amount which resulted in an impairment of US$101.4 million. The recoverable amount was based on the fair value less cost of disposal (“FVLCOD”) of the investment (level 2 of the fair value hierarchy). FVLCOD was indirectly derived from the market value of Lepanto Consolidated Mining Company, being the 60% shareholder of FSE. The impairment is included in the “Corporate and other” segment.

3 Following the Group’s decision during 2013 to dispose of non-core projects, APP was classified as held for sale and, accordingly, valued at the lower of fair value less cost of disposal or carrying value which resulted in impairments of US$89.7 million and US$3.2 million during 2013 and 2014, respectively. APP’s carrying value at 31 December 2014 after the above impairments was US$40.0 million which was based on an offer received close to the 2014 year-end. During 2015, active marketing activities for the disposal of the project continued after the 2014 offer was not realised. During 2015, APP was further impaired by US$39.0 million, resulting in a carrying value of US$1.0 million at 31 December 2015. The impairment is included in the “Corporate and other” segment. At 31 December 2016, APP no longer met the definition of an asset held for sale and was reclassified to property, plant and equipment at a recoverable amount of US$1.0 million. During 2017, active marketing activities continued and as a result, a sale agreement was concluded comprising a purchase offer of US$40.0 million cash and a 2% net smelter refiner royalty on all metals. As a result, the impairment of US$39.0 million previously recorded, was reversed and APP was reclassified as an asset held for sale at 31 December 2017. Refer note 12 for further details.

4 Reversal of impairment and impairment of property, plant and equipment is made up as follows:

	UNITED STATES DOLLAR
	2017			2016			2015
– Redundant assets at Cerro Corona (2015: Cerro Corona)		(0.8	)		—			(6.7	)
– Reversal of cash-generating unit impairment at Cerro Corona (2016: impairment of $66.4 million)		53.4			(66.4	)		—
(The impairment in 2016 was due to the reduction in gold and copper reserves due to depletion, a decrease in the gold and copper price assumptions for 2017 and 2018, a lower resource price and an increase in the Peru tax rate. The reversal of the impairment in 2017 was due to a higher value-in-use following the completion of a pre-feasibility study in 2017, with the assistance of external specialists, extending the life-of-mine from 2023 to 2030 by optimising the tailings density and increasing the tailings capacity by using in-pit tailings after mining activities end. After taking into account one year amortisation, the reversal of impairment amounted to US$53.4 million (2016: The recoverable amount was based on its FVLCOD calculated using a combination of the market and the income approach (level 3 of the fair value hierarchy)). Refer to accounting policies on page 139 for assumptions).
– Damang assets held for sale		—			(7.6	)		—
(Following the Damang re-investment plan, a decision was taken to sell certain mining fleet assets and related spares. The sale of the assets is expected to be concluded during 2017. As a result, the assets were classified as held for sale (refer note 12) and valued at the lower of FVLCOD or carrying value which resulted in an impairment of US$7.6 million).
– Asset-specific impairment at Tarkwa		(6.8	)		—			—
(Relating to aged, high maintenance and low effectiveness mining fleet that is no longer used).
– Asset-specific impairment at Damang		(3.5	)		(2.4	)		(35.8	)
(Relating to all assets at the Rex pit. Following a series of optimisations, the extensional drilling, completed in 2017, failed to deliver sufficient tonnages at viable grades to warrant further work (2016: inoperable mining fleet that is no longer used under the current life-of-mine plan, 2015: Immovable mining assets written off to nil that would no longer be used under the current life-of-mine plan)).
Reversal of impairment and impairment of property, plant and equipment – other		42.3			(76.4)			(42.5)

5 At 31 December 2017, the Group recognised an impairment of R3,495.0 billion (US$277.8 million) at South Deep. The recoverable amount was based on its FVLCOD calculated using a combination of the market and the income approach (level 3 of the fair value hierarchy). The impairment calculation was based on the 2017 life-of-mine plan using the following assumptions:

- Gold price of R525,000 per kilogram;

- Resource price of US$17 per ounce at the Rand/Dollar exchange rate of R12.58;

- Resource ounces of 29.0 million ounces;

- Life-of-mine: 78 years; and

- Discount rate: 13.5% nominal.

The impairment is due to a reduction in the gold price assumptions, a lower resource price and a deferral of production.

2 The Mineral and Petroleum Resource Royalty Act 2008 (“Royalty Act”) was promulgated on 24 November 2008 and became effective from 1 March 2010. The Royalty Act imposes a royalty on refined (mineral resources that have undergone a comprehensive level of beneficiation such as smelting and refining as defined in Schedule 1 of the Act) and unrefined (mineral resources that have undergone limited beneficiation as defined in Schedule 2 of the Act) minerals payable to the state. The royalty in respect of refined minerals (which include gold refined to 99.5% and above and platinum) is calculated by dividing earnings before interest and taxes (“EBIT”) by the product of 12.5 times gross revenue calculated as a percentage, plus an additional 0.5%. EBIT refers to taxable mining income (with certain exceptions such as no deduction for interest payable and foreign exchange losses) before assessed losses but after capital expenditure. A maximum royalty of 5% has been introduced on refined minerals. The effective rate of royalty tax payable for the year ended 31 December 2017 was 0.5% of mining revenue (2016: 0.5% and 2015: 0.5%) equalling the minimum charge per the formula.

3 The Australian operations are subject to a 2.5% (2016: 2.5% and 2015: 2.5%) gold royalty on revenue as the mineral rights are owned by the state.

4 Minerals are owned by the Republic of Ghana and held in trust by the President. During 2016, Gold Fields signed a Development Agreement (“DA”) with the Government of Ghana for both the Tarkwa and Damang mines. This agreement stated that the Ghanaian operations will be subject to a sliding scale for royalty rates, linked to the prevailing gold price (effective 1 January 2017). The sliding scale is as follows:

Average gold price
Low value			High value		Royalty rate
	US$0.00	-		US$1,299.99		3.0	%
	US$1,300.00	-		US$1,499.99		3.5	%
	US$1,450.00	-		US$2,299.99		4.1	%
	US$2,300.00	-		Unlimited		5.0	%

During 2016 and 2015, the Ghanaian operations were subject to a 5.0% gold royalty on revenue.

5 The Peruvian operations are subject to a mining royalty calculated on a sliding scale with rates ranging from 1% to 12% of the value of operating profit.

2 Deferred tax assets not recognised on impairment of investments relate to the impairment and reversal of impairment of FSE, Hummingbird and APP. Refer to note 6 for details of impairments.

3 The functional currency of Cerro Corona is US Dollar, however, the Peruvian tax base is based on values in Peruvian Nuevo Sol.

4 Deferred tax assets amounting to US$12.9 million (2016: US$34.9 million and 2015: US$112.5 million) were not recognised during the year at Cerro Corona and Damang to the extent that there is insufficient future taxable income available. At Cerro Corona, deferred tax assets amounting to US$12.9 million (2016: US$33.5 million and 2015: US$76.9 million) were not recognised during the year related to deductible temporary differences on additions to fixed assets in the current financial year that would only reverse after the end of the life-of-mine (“LoM”) of Cerro Corona. At Damang, deferred tax assets amounting to US$nil (2016: US$1.4 million and 2015: US$35.6 million) were not recognised during the year related to net deductible temporary differences reversing in the current financial year. In making this determination, the Group analysed, among others, forecasts of future earnings and the nature and timing of future deductions and benefits represented by deferred tax assets.

5 Due to year-end assessments, deferred tax assets amounting to US$17.3 million and US$2.5 million were recognised at Cerro Corona and Damang, respectively, to the extent that there is sufficient future taxable income available. During 2017, Cerro Corona completed a pre-feasibility study extending the life-of-mine (“LoM”) from 2023 to 2030. A significant portion of the deductible temporary differences on fixed assets that were scheduled to reverse after the end of the LoM at Cerro Corona will now reverse over the extended LoM, resulting in the recognition of deferred tax assets amounting to US$17.3 million. At Damang, the LoM indicated that the mine would make taxable profits in the future that would support the write back of a portion of the deferred tax asset amounting to US$2.5 million. In making this determination, the Group analysed, among others, forecasts of future earnings and the nature and timing of future deductions and benefits represented by deferred tax assets.

1 South African mining tax on mining income is determined according to a formula which takes into account the profit and revenue from mining operations. South African mining taxable income is determined after the deduction of all mining capital expenditure, with the proviso that this cannot result in an assessed loss. Capital expenditure amounts not deducted are carried forward as unredeemed capital expenditure to be deducted from future mining income. Accounting depreciation is ignored for the purpose of calculating South African mining taxation. The effective mining tax rate for Gold Fields Operations Limited (“GFO”) and GFI Joint Venture Holdings Proprietary Limited (“GFIJVH”), owners of the South Deep mine, has been calculated at 30% (2016: 30% and 2015: 30%).

2 Non-mining income of South African mining operations consists primarily of interest income.

3 On 11 March 2016, Gold Fields signed a development agreement with the Government of Ghana for both the Tarkwa and Damang mines. This agreement resulted in a reduction in the corporate tax rate from 35.0% to 32.5%, effective 17 March 2016.

Summary of Estimated Available for Set-off Against Future Income Pre Tax

1 These deductions are available to be utilised against income generated by the relevant tax entity and do not expire unless the tax entity concerned ceases to operate for a period of longer than one year. Under South African mining tax ring-fencing legislation, each tax entity is treated separately and as such these deductions can only be utilised by the tax entities in which the deductions have been generated. South African tax losses and unredeemed capital expenditure have no expiration date.

2 The above R2,427.1 million (2016: R1,929.2 million) comprises US$925.5 million gross recognised capital allowance and US$1,501.6 million gross unrecognised capital allowance (2016: US$796.6 million gross recognised capital allowance and US$1,132.6 million gross unrecognised capital allowance).

3 During 2014, the South African Revenue Services (“SARS”) issued a Finalisation of Audit Letter (“the Audit Letter”) stating that SARS has disallowed US$182.2 million of GFIJVH’s gross recognised capital allowance of US$925.5 million. Refer note 34 on Contingent Liabilities for further details.

4 The total tax losses of US$445.9 million (2016: US$388.8 million) comprise US$22.9 million (2016: US$10.9 million) tax losses that expire between one and two years, US$57.6 million (2016: US$58.9 million) tax losses that expire between two and five years, US$30.4 million (2016: US$41.2 million) tax losses that expire between five and 10 years, US$43.2 million (2016: US$40.6 million) tax losses that expire after 10 years and US$291.8 million (2016: US$237.2 million) tax losses that have no expiry date.

5 The tax losses are available to be utilised against income generated by the relevant tax entity and do not expire.

6 Tax losses may be carried forward for five years. These losses expire on a first-in-first-out basis. Tax losses of US$44.5 million (2016: US$46.3 million) expire in two years, tax losses of US$19.0 million (2016: US$nil) expire in three years, tax losses of US$91.7 million (2016: US$19.4 million) expire in four years and tax losses of US$46.2 million (2016: US$3.0 million) expire in five years.

1 Following the Damang re-investment plan, a decision was taken during 2016 to sell certain mining fleet assets and related spares. As a result, the assets were classified as held for sale at 31 December 2016 and valued at the lower of FVLCOD or carrying value which resulted in an impairment of US$7.6 million. The sale of the assets concluded during 2017.

Mining fleet and related spares with carrying values of US$18.6 million and US$7.8 million, respectively, were reclassified to assets held for sale. Refer note 13 and 19 for further details.

2 At 31 December 2016, APP no longer met the definition of an asset held for sale and was reclassified to property, plant and equipment at a recoverable amount of US$1.0 million. During 2017, active marketing activities continued and as a result, a sale agreement was concluded comprising a purchase offer of US$40.0 million cash and a 2% net smelter refiner royalty on all metals. As a result, the impairment previously recorded, was reversed up to the value of the selling price and APP was reclassified as an asset held for sale at 31 December 2017.

1 Included in the cost of mine development, infrastructure and other assets are exploration and evaluation assets amounting to US$10.8 million (2016: US$9.1 million).

2 Based on conversion of resources to reserves a portion of the cost of the mineral rights asset at the Australian operations is allocated from the non-depreciable component of the mineral rights asset to a depreciable component, at this point the mineral rights asset is reclassified from land, mineral rights and rehabilitation assets to mine development, infrastructure and other assets on a mine-by-mine basis. This reclassification relates to the transfer from the non-depreciable to the depreciable component for all periods from acquisition of the mineral rights to the year ended 31 December 2015 given the correction in methodology of the mineral rights asset. On an annual basis transfers are reflected as reclassifications.

3 Refer note 40 for further details.

4 The additions of US$275.9 million (A$372.4 million) are made up of US$197.1 million (A$266.0 million) cash additions and US$78.8 million (A$106.4 million) non-cash additions. Refer note 15.2 for further details.

5 Borrowing costs of US$22.9 million (2016: US$15.1 million) arising on Group general borrowings were capitalised during the period and comprised US$19.4 million (US$15.1 million) borrowing costs related to the qualifying projects at South Deep, US$2.1 million (2016: US$nil) borrowing costs related to the Damang reinvestment project and US$1.4 million (2016: US$nil) borrowing costs related to the Gruyere project. An average interest capitalisation rate of 5.3% (2016: 4.7%) was applied.

6 The impairment reversal of US$81.3 million (2016: charge of US$76.4 million) is made up of US$11.1 million (2016: US$76.4 million) impairment of property, plant and equipment, offset by the reversal of APP impairment amounting to US$39.0 million (refer note 6 for details) and the reversal of the Cerro Corona cash-generating unit impairment of US$53.4 million (refer note 6 for further details).

7 The write-off of exploration and evaluation assets is due to specific exploration programmes not yielding results to warrant further exploration at the Group’s Australian operations and the US$51.5 million (2016: US$41.4 million) for continuing operations is included in the US$109.8 million (2016: US$86.1 million) “Exploration expense” in the consolidated income statement.

8 Fleet assets and carbon-in-leach (“CIL”) plant in Ghana amounting to US$183.6 million (2016: US$95.5 million) have been pledged as security for the US$100 million senior secured revolving credit facility (refer note 24).

Summary of Equity Method Investment in Joint Venture - Far Southeast Gold Resources Incorporated ("FSE")

(a)	Far Southeast Gold Resources Incorporated (“FSE”)
	Gold Fields’ interest in FSE, an unlisted entity, was 40% (2016: 40%) at 31 December 2017.
	Gold Fields paid US$10.0 million in option fees to Lepanto Consolidated Mining Company (“Lepanto”) during the six months ended 31 December 2010. In addition, Gold Fields paid non-refundable down payments of US$66.0 million during the year ended 31 December 2011 and US$44.0 million during the six months ended 31 December 2010 to Liberty Express Assets in accordance with the agreement concluded whereby the Group has the option to acquire 60% of FSE. On 31 March 2012, Gold Fields acquired 40% of the issued share capital and voting rights of FSE by contributing an additional non-refundable down payment of US$110.0 million. Lepanto owns the remaining 60% shareholding in FSE.
	The remaining 20% option is not likely to be exercised until such time as FSE obtains a Foreign Technical Assistance Agreement (“FTAA”) which allows for direct majority foreign ownership and control.
	FSE has a 31 December year-end and has been equity accounted since 1 April 2012. FSE’s equity accounting is based on results to 31 December 2017.
	Investment in joint venture consists of:
	Unlisted shares at cost	230.0		230.0
	Equity contribution	79.3		77.7
	Cumulative impairment1	(101.4	)	(101.4	)
	Share of accumulated losses brought forward	(77.7	)	(75.4	)
	Share of loss after taxation2	(1.6	)	(2.3	)
	Total investment in joint venture3	128.6		128.6

1 Refer note 6 for details of impairment.

2 Gold Fields’ share of loss after taxation represents exploration and other costs, including work completed on a scoping study, which is fully funded by Gold Fields as part of their equity contribution.

3 FSE is a company incorporated under the laws of the Philippines and owns the gold-copper Far Southeast exploration project (the “FSE project”). During the exploration phase of the FSE project and as long as the 20% option remains exercisable, the Group has joint control over the FSE project. The Group will only have the power to direct the activities of FSE once it exercises the option to acquire the additional 20% shareholding in FSE, which is only exercisable once an FTAA is obtained. FSE has no revenues or significant assets or liabilities. Assets included in FSE represent the rights to explore and eventually mine the FSE project.

Total investments in associates	42.7	42.1

¹  During 2016, the Group’s holding was diluted from 21.6% to 8.8% following the issue of new shares by Bezant. In line with the Group’s accounting policy, this resulted in Bezant no longer being accounted for as an equity-accounted investee and was re-classified to available-for-sale financial investments.

²  Represents a holding of 25.7% in Rusoro.

The carrying value of Rusoro was written down to US$nil at 31 December 2010 due to losses incurred by the entity. The fair value, based on the quoted market price of the investment was US$7.7 million and US$23.9 million at 31 December 2017 and 31 December 2016, respectively. The unrecognised share of loss of Rusoro for the year amounted to US$2.0 million (2016: unrecognised shares of profits of US$18.7 million and 2015: unrecognised share of loss of US$3.6 million). The cumulative unrecognised share of losses of Rusoro amounted to US$196.0 million (2016: US$194.0 million).

On 22 August 2016, the Arbitration Tribunal, operating under the Additional Facility Rules of the World Bank’s International Centre for the Settlement of Investment Disputes, awarded Rusoro damages of US$967.8 million plus pre and post-award interest which currently equates to in excess of US$1.2 billion in the arbitration brought by Rusoro against the Bolivarian Republic of Venezuela (“Venezuela”).

Venezuela has not complied with the arbitration award terms, which were issued on 22 August 2016. On 6 December 2017, Rusoro obtained a judgement against Venezuela in the Superior Court of Justice in Ontario, Canada, in excess of US$1.3 billion. The judgement, which was issued on default as a result of Venezuela’s failure to appear before the Ontario court, arose out of Rusoro’s ongoing dispute with Venezuela over the South American nation’s seizure of its gold mining properties in the country. The Canadian judgement, which confirmed an arbitration award issued in Rusoro’s favour in the same amount, was issued on 25 April 2017. Venezuela did not appeal or seek to vacate the judgement, and its time to do so expired.

Rusoro further filed a suit in the Supreme Court of the State of New York, seeking recognition of the Canadian judgement. Rusoro brought the New York lawsuit in addition to an action it filed in the US District Court for the District of Columbia, which seeks recognition of and the entry of judgement on the original arbitration award. A favourable ruling from either the New York or DC court will entitle Rusoro to use all legal procedures - including broad discovery from both Venezuela and third parties - that US law provides judgement creditors. Any judgement issued in New York will also accrue interest at 9% per annum until the judgement is fully paid.

Management has not recognised this amount due to the uncertainty over its recoverability.

1 The balance is net of unamortised transaction costs amounting to US$4.5 million (2016: US$6.0 million) which will unwind over the remaining period of the notes as an interest expense.

The payment of all amounts due in respect of the Notes is unconditionally and irrevocably guaranteed by Gold Fields Limited (“Gold Fields”), Sibanye-Stillwater (up to 24 April 2015), Gold Fields Operations Limited (“GFO”) and Gold Fields Holdings Company (BVI) Limited (“GF Holdings”) (collectively “the Guarantors”), on a joint and several basis.

The notes and guarantees constitute direct, unsubordinated and unsecured obligations of Orogen and the Guarantors, respectively, and rank equally in right of payment among themselves and with all other existing and future unsubordinated and unsecured obligations of Orogen and the Guarantors, respectively.

Gold Fields Australasia Proprietary Limited (“GFA”) offered and accepted the purchase of an aggregate principal amount of notes equal to US$147.6 million at the purchase price of US$880 per US$1,000 in principal amount of notes. GFA intends to hold the notes acquired until their maturity on 7 October 2020. The purchase of the notes amounting to US$147.6 million was financed by drawing down under the US$1,510 million term loan and revolving credit facilities. The Group recognised a profit of US$17.7 million on the buy back of the notes.

2 Borrowings under the revolving senior secured credit facility are secured by first-ranking assignments of all rights, title and interest in all of La Cima’s concentrate sale agreements. In addition, the offshore and onshore collection accounts of La Cima are subject to an account control agreement and a first-ranking charge in favour of the lenders. This facility is non-recourse to the rest of the Group. The old revolving senior secured credit facility matured in 2017 and was refinanced through the new revolving credit facility on 22 September 2017.

3 Borrowings under the facility are guaranteed by Gold Fields Ghana Limited and Abosso Goldfields Limited. Borrowings under this facility are also secured by the registration of security over certain fleet vehicles owned by GF Ghana and Abosso (“Secured Assets”). In addition, the lenders are noted as first loss payees under the insurance contracts in respect of the Secured Assets and are assigned the rights under the maintenance contracts between certain suppliers of the Secured Assets. This facility is non-recourse to the rest of the Group. The US$70 million revolving senior secured credit facility matured in 2017 and was refinanced through the US$100 million revolving senior secured credit facility on 21 July 2017.

Fleet assets and CIL plant in Ghana amounting to US$183.6 million (2016: US$95.5 million) have been pledged as security for this facility.

4 Borrowings under this facility are guaranteed by Gold Fields, GF Holdings, Orogen, GFO, GFIJVH and Gold Fields Ghana Holdings (BVI) Limited (“GF Ghana”).

5 Borrowings under these facilities were guaranteed by Gold Fields, GF Holdings, Orogen, GFO and GFIJVH.

These facilities were cancelled and refinanced through the US$1,290 million term loan and revolving credit facilities on 6 June 2016, resulting in the total amount available to be US$nil at 31 December 2016.

6 Borrowings under this facility are guaranteed by Gold Fields, GF Holdings, Orogen, GFO, GFIJVH and Gold Fields Ghana Holdings (BVI) Limited (“GF Ghana”).

7 Borrowings under this facility are guaranteed by Gold Fields, GFO, GF Holdings, Orogen and GFIJVH

8 The Group utilised uncommitted loan facilities from some of the major banks to fund the capital expenditure and working capital requirements of the South African operation. These facilities have no fixed terms, are short-term in nature and interest rates are market related. Borrowings under these facilities are guaranteed by Gold Fields.

1 Changes in estimates are defined as changes in reserves and corresponding changes in life-of-mine as well as changes in laws and regulations governing environmental matters, closure cost estimates and discount rates.  

2 South African, Ghanaian, Australian and Peruvian mining companies are required by law to undertake rehabilitation as part of their ongoing operations. These environmental rehabilitation costs are funded as follows:

- Ghana - reclamation bonds underwritten by banks and restricted cash (refer note 18);

- South Africa - contributions into environmental trust funds (refer note 18) and guarantees;

- Australia - mine rehabilitation fund levy; and

- Peru - bank guarantees.

1 The principal health risks associated with Gold Fields’ mining operations in South Africa arise from occupational exposure to silica dust, noise, heat and certain hazardous chemicals. The most significant occupational diseases affecting Gold Fields’ workforce include lung diseases (such as silicosis, tuberculosis, a combination of the two and chronic obstructive airways disease (“COAD”) as well as noise-induced hearing loss (“NIHL”)).

A consolidated application was brought against several South African mining companies, including Gold Fields, for certification of a class action on behalf of current or former mineworkers (and their dependants) who have allegedly contracted silicosis and/or tuberculosis while working for one or more of the mining companies listed in the application.

The Occupational Lung Disease Working Group was formed in fiscal 2014 to address issues relating to compensation and medical care for occupational lung disease in the South African gold mining industry.

The Working Group, made up of African Rainbow Minerals, Anglo American SA, AngloGold Ashanti, Gold Fields, Harmony and Sibanye-Stillwater, has had extensive engagements with a wide range of stakeholders since its formation, including government, organised labour, other mining companies and the legal representatives of claimants who have filed legal actions against the companies.

The members of the Working Group are among respondent companies in a number of legal proceedings related to occupational lung disease, including the class action referred to above. The Working Group is, however, of the view that achieving a comprehensive settlement which is fair to both past, present and future employees and sustainable for the sector, is preferable to protracted litigation.

This matter was previously disclosed as a contingent liability as the amount could not be estimated reliably. As a result of the ongoing work of the Working Group and engagements with affected stakeholders since 31 December 2016, it has now become possible for Gold Fields to reliably estimate its share in the estimated cost in relation to the Working Group of a possible settlement of the class action claims and related costs. As a result, Gold Fields has provided an amount of US$31.9 million (R401.6 million) for this obligation in the statement of financial position at 31 December 2017. The nominal amount of this provision is US$40.5 million (R509.0 million)

The assumptions that were made in the determination of the provision include silicosis prevalence rates, estimated settlement per claimant, benefit take-up rates and disease progression rates. A discount rate of 8.24% was used, based on government bonds with similar terms to the anticipated settlements.

The ultimate outcome of these matters remains uncertain, with a possible failure to reach a settlement or to obtain the requisite court approval for a potential settlement. The provision is consequently subject to adjustment in the future, depending on the progress of the Working Group discussions, stakeholder engagements and the ongoing legal proceedings (refer note 34 for further details).

The above is a geographical analysis presented by location of assets.

The Group’s continuing operations are primarily involved in gold mining, exploration and related activities. Activities are conducted and investments held both inside and outside South Africa. The segment results have been prepared and presented based on management’s reporting format. Gold mining operations are managed and internally reported based on the following geographical areas: in South Africa, South Deep mine, in Ghana, Tarkwa and Damang mines, in Australia, St Ives, Agnew/Lawlers, Granny Smith and Gruyere Gold Project and in Peru, the Cerro Corona mine. While the Gruyere Gold Project does not meet the quantitative criteria for disclosure as a separate segment, it is expected to become a significant contributor to the Group’s performance in future years as the project is being developed. The Group also has exploration interests which are included in the “Corporate and other” segment. Refer to accounting policies on segment reporting on page 151.

The Group’s discontinued operation was primarily involved in gold mining, exploration and related activities. Activities are conducted and investments held in Australia.

US Dollar figures may not add as they are rounded independently.

1 The income statement and statement of financial position of South Deep is that of the operating mine and does not include any of the adjustments made in respect of the purchase price allocation relating to the acquisition of South Deep (refer note 14). South Deep Gold mine, being an unincorporated joint venture, is not liable for taxation. Taxation included in South Deep is indicative, as tax is provided in the holding companies at a rate of 30%.

2 “Corporate and other” represents the items to reconcile segment data to consolidated financial statement totals, including the elimination of intercompany transactions and balances as well as the Group’s exploration interests. This does not represent a separate segment as it does not generate revenue. Included in “Corporate and other” is the adjustment made in respect of the purchase price allocation, including goodwill relating to the acquisition of South Deep.

3 Other costs “Corporate and other” comprise share of loss of associates, net of taxation of US$1.3 million and the balance of US$9.0 million consists mainly of corporate related costs.

4 The Australian operations are entitled to transfer and off-set profits and losses from one company to another, therefore it is not meaningful to split the royalties, income or deferred taxation.

The above is a geographical analysis presented by location of assets.

The Group’s continuing operations are primarily involved in gold mining, exploration and related activities. Activities are conducted and investments held both inside and outside South Africa. The segment results have been prepared and presented based on management’s reporting format. Gold mining operations are managed and internally reported based on the following geographical areas: in South Africa, South Deep mine, in Ghana, Tarkwa and Damang mines, in Australia, St Ives, Agnew/Lawlers, Granny Smith and Gruyere Gold Project and in Peru, the Cerro Corona mine. While the Gruyere Gold Project does not meet the quantitative criteria for disclosure as a separate segment, it is expected to become a significant contributor to the Group’s performance in future years as the project is being developed. The Group also has exploration interests which are included in the “Corporate and other” segment. Refer to accounting policies on segment reporting on page 151.

The Group’s discontinued operation was primarily involved in gold mining, exploration and related activities. Activities are conducted and investments held in Australia.

US Dollar figures may not add as they are rounded independently.

1 The income statement and statement of financial position of South Deep is that of the operating mine and does not include any of the adjustments made in respect of the purchase price allocation relating to the acquisition of South Deep (refer note 14). South Deep Gold mine, being an unincorporated joint venture, is not liable for taxation. Taxation included in South Deep is indicative, as tax is provided in the holding companies at a rate of 30%.

2 “Corporate and other” represents the items to reconcile segment data to consolidated financial statement totals, including the elimination of intercompany transactions and balances as well as the Group’s exploration interests. This does not represent a separate segment as it does not generate revenue. Included in “Corporate and other” is the adjustment made in respect of the purchase price allocation, including goodwill relating to the acquisition of South Deep.

3 Other costs “Corporate and other” comprise share of loss of associates net of taxation of US$2.3 million, profit on disposal of investments of US$2.3 million and the balance of US$23.1 million consists mainly of corporate related costs.

4 The Australian operations are entitled to transfer and off-set profits and losses from one company to another, therefore it is not meaningful to split the royalties, income or deferred taxation.

Standard(s) Amendment(s) Interpretation(s)	IFRS 9 Financial Instruments
Nature of the change	New standard
Salient features of the changes	• This IFRS sets out requirements for recognising and measuring financial assets, financial liabilities and some contracts to buy or sell non-financial items. This standard replaces IAS 39 Financial Instruments. The Group will adopt IFRS 9 on 1 January 2018; • This IFRS contains a new classification and measurement approach for financial assets that reflects the business model in which the assets are managed and their cash flow characteristics. The three principal classification categories for financial assets are: measured at amortised cost, fair value through profit or loss ("FVTPL") and fair value through other comprehensive income ("FVOCI"); • Based on the Group's assessment, the Group believes that the new classification if applied at 31 December 2017, would not have a significant impact on its accounting for financial assets. The Group's available-for-sale financial assets will be designated at FVOCI; and • The new measurement principles will not have a material impact on the Group.
Effective Date	Jan. 01, 2018
IFRS 15 Revenue from contracts with customers [member]
Disclosure of initial application of standards or interpretations [line items]
Standard(s) Amendment(s) Interpretation(s)	IFRS 15 Revenue from contracts with customers
Nature of the change	New standard
Salient features of the changes	• This IFRS introduces a new revenue recognition model for contracts with customers and establishes a comprehensive framework for determining whether, how much and when revenue is recognised. IFRS 15 also includes extensive new disclosure requirements; • The Group has assessed the impact of adopting IFRS 15 and has determined the impact as follows: • Revenue will be recognised when the customer takes control of the gold, copper and silver. The timing of recognition of revenue will no longer be when risks and rewards of ownership pass to the customer; • The change in timing of revenue recognition will result in revenue at the South African and Australian operations being recognised on settlement date (date when control passes) and not contract date (previous date when risks and rewards of ownership pass). There is no change to the revenue recognition at any of the other operations given that the date of control is the same date as when risks and rewards of ownership pass. The change in timing of revenue recognition for the South African and Australian operations will be that revenue will be recognised approximately two days later than it currently is recognised. As approximately 0.3% of 2017 revenue will now be recognised in 2018, the adoption of IFRS 15 will not have a material impact on the revenue of the Group; and • The Group will adopt IFRS 15 using the cumulative effect method, with the effect of initially applying this standard at the date of initial application (i.e. 1 January 2018). As a result, the Group will not apply the requirements of IFRS 15 to the comparative periods presented.
Effective Date	Jan. 01, 2018
IFRS 16 Leases [member]
Disclosure of initial application of standards or interpretations [line items]
Standard(s) Amendment(s) Interpretation(s)	IFRS 16 Leases
Nature of the change	New standard
Salient features of the changes	• This IFRS sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract, i.e. the customer ('lessee') and the supplier ('lessor'); • IFRS 16 replaces the previous leases Standard, IAS 17 Leases, and related Interpretations; • IFRS 16 has one model for lessees which will result in almost all leases being included on the statement of financial position. No significant changes have been included for lessors; and • Management has commenced compiling a list of all potential leases and is in the process of reviewing all such contracts in order to assess the impact the standard will have on the Group.
Effective Date	Jan. 01, 2019
IFRIC 23 Uncertainty over Income Tax Treatments [member]
Disclosure of initial application of standards or interpretations [line items]
Standard(s) Amendment(s) Interpretation(s)	IFRIC 23 Uncertainty over Income Tax Treatments
Nature of the change	New interpretation
Salient features of the changes	• This interpretation clarifies the accounting for income tax treatments that have yet to be accepted by tax authorities; • IFRIC 23 specifically clarifies how to incorporate this uncertainty into the measurement of tax as reported in the financial statements; • IFRIC 23 does not introduce any new disclosures but reinforces the need to comply with existing disclosure requirements about judgements made, assumptions and other estimates used and the potential impact of uncertainties that are not reflected • The interpretation will not have a material impact on the Group.
Effective Date	Jan. 01, 2019

[3] At 31 December 2017, the Group recognised an impairment of R3,495.0 billion (US$277.8 million) at South Deep. The recoverable amount was based on its FVLCOD calculated using a combination of the market and the income approach (level 3 of the fair value hierarchy). The impairment calculation was based on the 2017 life-of-mine plan using the following assumptions: - Gold price of R525,000 per kilogram; - Resource price of US$17 per ounce at the Rand/Dollar exchange rate of R12.58; - Resource ounces of 29.0 million ounces; - Life-of-mine: 78 years; and - Discount rate: 13.5% nominal. The impairment is due to a reduction in the gold price assumptions, a lower resource price and a deferral of production.

[4] Following the Group's decision during 2013 to dispose of non-core projects, APP was classified as held for sale and, accordingly, valued at the lower of fair value less cost of disposal or carrying value which resulted in impairments of US$89.7 million and US$3.2 million during 2013 and 2014, respectively. APP's carrying value at 31 December 2014 after the above impairments was US$40.0 million which was based on an offer received close to the 2014 year-end. During 2015, active marketing activities for the disposal of the project continued after the 2014 offer was not realised. During 2015, APP was further impaired by US$39.0 million, resulting in a carrying value of US$1.0 million at 31 December 2015. The impairment is included in the "Corporate and other" segment. At 31 December 2016, APP no longer met the definition of an asset held for sale and was reclassified to property, plant and equipment at a recoverable amount of US$1.0 million. During 2017, active marketing activities continued and as a result, a sale agreement was concluded comprising a purchase offer of US$40.0 million cash and a 2% net smelter refiner royalty on all metals. As a result, the impairment of US$39.0 million previously recorded, was reversed and APP was reclassified as an asset held for sale at 31 December 2017. Refer note 12 for further details.

[5] Reversal of impairment and impairment of property, plant and equipment is made up as follows: UNITED STATES DOLLAR 2017 2016 2015 - Redundant assets at Cerro Corona (2015: Cerro Corona) (0.8 ) - (6.7 ) - Reversal of cash-generating unit impairment at Cerro Corona (2016: impairment of $66.4 million) 53.4 (66.4 ) - (The impairment in 2016 was due to the reduction in gold and copper reserves due to depletion, a decrease in the gold and copper price assumptions for 2017 and 2018, a lower resource price and an increase in the Peru tax rate. The reversal of the impairment in 2017 was due to a higher value-in-use following the completion of a pre-feasibility study in 2017, with the assistance of external specialists, extending the life-of-mine from 2023 to 2030 by optimising the tailings density and increasing the tailings capacity by using in-pit tailings after mining activities end. After taking into account one year amortisation, the reversal of impairment amounted to US$53.4 million (2016: The recoverable amount was based on its FVLCOD calculated using a combination of the market and the income approach (level 3 of the fair value hierarchy)). Refer to accounting policies on page 139 for assumptions). - Damang assets held for sale - (7.6 ) - (Following the Damang re-investment plan, a decision was taken to sell certain mining fleet assets and related spares. The sale of the assets is expected to be concluded during 2017. As a result, the assets were classified as held for sale (refer note 12) and valued at the lower of FVLCOD or carrying value which resulted in an impairment of US$7.6 million). - Asset-specific impairment at Tarkwa (6.8 ) - - (Relating to aged, high maintenance and low effectiveness mining fleet that is no longer used). - Asset-specific impairment at Damang (3.5 ) (2.4 ) (35.8 ) (Relating to all assets at the Rex pit. Following a series of optimisations, the extensional drilling, completed in 2017, failed to deliver sufficient tonnages at viable grades to warrant further work (2016: inoperable mining fleet that is no longer used under the current life-of-mine plan, 2015: Immovable mining assets written off to nil that would no longer be used under the current life-of-mine plan)). Reversal of impairment and impairment of property, plant and equipment - other 42.3 (76.4) (42.5)

[6] Following the identification of impairment indicators at 30 June 2015, the investment in Hummingbird was valued at its recoverable amount, which resulted in an impairment of US$7.5 million. The recoverable amount was based on the investment's fair value at the time, being its quoted market price (level 1 of the fair value hierarchy). The impairment is included in the "Corporate and other" segment.

[7] Following the identification of impairment indicators at 31 December 2015, FSE was valued at its recoverable amount which resulted in an impairment of US$101.4 million. The recoverable amount was based on the fair value less cost of disposal ("FVLCOD") of the investment (level 2 of the fair value hierarchy). FVLCOD was indirectly derived from the market value of Lepanto Consolidated Mining Company, being the 60% shareholder of FSE. The impairment is included in the "Corporate and other" segment.

[2] Following the Group's decision during 2013 to dispose of non-core projects, APP was classified as held for sale and, accordingly, valued at the lower of fair value less cost of disposal or carrying value which resulted in impairments of US$89.7 million and US$3.2 million during 2013 and 2014, respectively. APP's carrying value at 31 December 2014 after the above impairments was US$40.0 million which was based on an offer received close to the 2014 year-end. During 2015, active marketing activities for the disposal of the project continued after the 2014 offer was not realised. During 2015, APP was further impaired by US$39.0 million, resulting in a carrying value of US$1.0 million at 31 December 2015. The impairment is included in the "Corporate and other" segment. At 31 December 2016, APP no longer met the definition of an asset held for sale and was reclassified to property, plant and equipment at a recoverable amount of US$1.0 million. During 2017, active marketing activities continued and as a result, a sale agreement was concluded comprising a purchase offer of US$40.0 million cash and a 2% net smelter refiner royalty on all metals. As a result, the impairment of US$39.0 million previously recorded, was reversed and APP was reclassified as an asset held for sale at 31 December 2017. Refer note 12 for further details.
