Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2019

Disclosure of significant accounting policies [Abstract]

The consolidated and company financial statements are prepared in compliance with International Financial Reporting Standards (IFRS) and Interpretations of those standards, as issued by the International Accounting Standards Board (IASB), Financial Reporting Pronouncements as issued by Financial Reporting Standards Council, JSE Listings Requirements and in the manner required by the South African Companies Act, 2008.

New standards and interpretations issued

The financial statements have been drawn up on the basis of accounting standards, interpretations and amendments effective at the beginning of the accounting period on 1 January 2019. The adoption of the new standards, interpretations and amendments effective from 1 January 2019 had the following impact on the group:

IFRS 16 Leases

The group elected to apply IFRS 16 utilising the modified retrospective approach, no cumulative effect of initially applying IFRS 16 was identified and recognised as an adjustment to the opening balance of retained earnings. The cumulative impact on the adoption of IFRS 16 resulted in the recognition of right of use assets, lease liabilities and the resultant deferred tax. Refer to Note 16 for the detail on the right of use assets and lease liabilities. Comparative information has not been restated.

For contracts previously classified as leases under IAS 17 Leases, the group has reassessed whether the contract is or contains a lease upon initial transition to the new standard and has also performed an assessment to identify significant contracts which have not previously classified as leases, but which may be a lease under the new standard.

The group applied the following practical expedients upon transition to IFRS 16:

Transition options:


•	Leases with a remaining contract period of less than 12 months will not be recorded on the statement of financial position and the lease payments will be expensed in the income statement on a straight-line basis.


•	The right-of-use asset is based on the lease liability recognised.

Practical expedients:


•	The short-term lease exemption - leases with a duration of one year or less will be expensed in the income statement on a straight-line basis.


•	The low value lease exemption - the group has elected to take the low value exemption with a value of $10k for the individual leased asset value. Further, the group has added an exception within its accounting policy to not capitalise leases with a net present value of $250k based on an IAS 1 materiality assessment.


•	Exclusion of initial direct costs for the measurement of the right of use asset at the date of initial application.


•	Use of hindsight in determining the lease term where the contract contains options to extend or terminate the lease.

The leases accounting policy applicable from 1 January 2019 is included under “Leases” in Annexure A.

Basis of Preparation

BASIS OF PREPARATION

The financial statements are prepared according to the historical cost convention, except for the revaluation of certain financial instruments to fair value. The group’s accounting policies as set out below are consistent in all material respects with those applied in the previous year except for the changes arising from the adoption of IFRS 16 as described in “New Standards and Interpretations Issued” above.

The comparative periods have been restated to separate continuing operations from discontinued operations in accordance with IFRS 5 Non-current Assets Held for Sale and Discontinued Operations, as a consequence of the classification of the sale of the South African producing assets and related liabilities as a discontinued operation. The sale agreement was announced on 12 February 2020.

The group financial statements are presented in US dollars.

Based on materiality, certain comparatives in the notes have been aggregated and comparatives have been restated to accord with current year disclosures. All notes are from continuing operations unless otherwise stated.

The group financial statements incorporate the financial statements of the company, its subsidiaries and its interests in joint ventures and associates. The financial statements of all material subsidiaries, the Environmental Rehabilitation Trust Fund, joint ventures and associates, are prepared for the same reporting period as the holding company, using the same accounting policies.

Subsidiaries are all entities over which the group has control. 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 entity. Control would generally exist where the group owns more than 50% of the voting rights, unless the group and other investors collectively control the entity where they must act together to direct the relevant activities. In such cases, as no investor individually controls the entity, the investment is accounted for as an associate, joint venture or a joint operation. Subsidiaries are fully consolidated from the date on which control is transferred to the group. They are deconsolidated from the date on which control ceases. The group re-assesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control.

Intra-group transactions, balances and unrealised gains and losses on transactions between group companies, including any resulting tax effects are eliminated.

Use of estimates

The preparation of the financial statements 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 Ore Reserve which is the basis of future cash flow estimates and unit-of-production depreciation, depletion and amortisation calculations; environmental, reclamation and closure obligations; asset impairments/reversals (including impairments of goodwill); recoverability of indirect taxes; and write-downs of inventory to net realisable value. Other estimates include employee benefit liabilities and unrecognised tax positions.

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 judgements that management has applied in the application of accounting policies, and the estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year, are discussed below.

Carrying value of tangible assets

Amortisation

The majority of mining assets are amortised using the units-of-production method where the mine operating plan calls for production from a well-defined proved and probable Ore Reserve.

For other tangible assets, the straight-line method is applied over the estimated useful life of the asset which does not exceed the estimated mine life based on proved and probable Ore Reserve as the useful lives of these assets are considered to be limited to the life of the relevant mine.

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 Ore Reserve. This would generally arise from the following factors:

•changes in proved and probable Ore Reserve;

•variations in the grade of Ore Reserve, which may be significant from time to time;

•differences between actual commodity prices and commodity price assumptions;

•unforeseen operational issues at mine sites; and

•changes in capital, operating, mining, processing and reclamation costs, discount rates and foreign exchange rates.

Changes in proved and probable Ore Reserve could similarly impact the useful lives of assets amortised on the straight-line method, where those lives are limited to the life of the mine.

Stripping costs

The group has a number of surface mining operations that are in the production phase for which production stripping costs are incurred. The benefits that accrue to the group as a result of incurring production stripping costs include (a) ore that can be used to produce inventory and (b) improved access to further quantities of material that will be mined in future periods.

The production stripping costs relating to improved access to further quantities of material in future periods are capitalised as a stripping activity asset, if and only if, all of the following are met:


•	It is probable that the future economic benefit (improved access to the orebody) associated with the stripping activity will flow to the group;


•	The group can identify the component of the orebody for which access has been improved; and


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

Components of the various orebodies at the operations of the group are determined based on the geological areas identified for each of the orebodies and are reflected in the Ore Reserve reporting of the group. In determining whether any production stripping costs should be capitalised as a stripping activity asset, the group uses three operational guidance measures; two of which relate to production measures, while the third relates to an average stripping ratio measure.

Once determined that any portion of the production stripping costs should be capitalised, the group determines the amount of the production stripping costs that should be capitalised with reference to the average mine costs per tonne of the component and the actual waste tonnes that should be deferred. Stripping activity assets are amortised on the units-of-production method based on the Ore Reserve of the component or components of the orebody to which these assets relate.

This accounting treatment is consistent with that for stripping costs incurred during the development phase of a pit, before production commences, except that stripping costs incurred during the development phase of a pit, before production commences, are amortised on the units-of-production method based on the Ore Reserve of the pit.

Deferred stripping costs are included in ‘Mine development costs’, within tangible assets. These costs form part of the total investment in the relevant cash-generating unit, which is reviewed for impairment if events or a change in circumstances indicate that the carrying value may not be recoverable. Amortisation of stripping activity assets is included in operating costs.

Impairment

The group reviews and tests the carrying value of tangible assets when events or changes in circumstances indicate that the carrying amount may not be recoverable. Assets are grouped at the lowest level for which identifiable cash flows are largely independent of cash flows of other assets, which is generally at the individual mine level. If there are indications that impairment may have occurred, estimates are prepared of expected future cash flows for each group of assets. Expected future cash flows used to determine the value in use of goodwill and tangible assets are inherently uncertain and could materially change over time and impact the recoverable amounts. The cash flows and value in use are significantly affected by a number of factors including published reserves, resources, exploration potential and production estimates, together with economic factors such as spot and future metal prices, discount rates, foreign currency exchange rates, estimates of costs to produce reserves and future capital expenditure. At the reporting date the group assesses whether any of the indicators which gave rise to previously recognised impairments have changed such that the impairment loss no longer exists or may have decreased. The impairment loss is then assessed on the original factors for reversal and if indicated, such reversal is recognised.

The recoverable amount is estimated based on the positive indicators. If an impairment loss has decreased, the carrying amount is recorded at the recoverable amount as limited in terms of IAS 36 Impairment of Assets.

Tangible assets

Tangible assets are recorded at cost less accumulated amortisation and impairments/reversals. Cost includes pre-production expenditure incurred during the development of a mine and the present value of related future decommissioning costs.

Interest on borrowings relating to the financing of major capital projects under construction is capitalised during the construction phase as part of the cost of the project. Such borrowing costs are capitalised over the period during which the asset is being acquired or constructed and borrowings have been incurred. Capitalisation ceases when construction is interrupted for an extended period or when the asset is substantially complete. Other borrowing costs are expensed as incurred.

If there is an indication that the recoverable amount of any of the tangible assets is less than the carrying value, the recoverable amount is estimated and the difference is recognised as an impairment.

Subsequent costs are included in the asset’s carrying amount only when it is probable that future economic benefits associated with the asset will flow to the group, and the cost of the addition can be measured reliably. All other repairs and maintenance are charged to the income statement during the financial period in which they are incurred.

To the extent a legal or constructive obligation to a third party exists, the acquisition cost includes estimated costs of dismantling and removing the asset and restoring the site. A change in estimated expenditures for dismantling, removal and restoration is added to or deducted from the carrying value of the related asset. To the extent that the change would result in a negative carrying amount for the related asset, this effect is recognised as income. The change in depreciation charge is recognised prospectively.

For assets amortised on the units-of-production method, amortisation is calculated to allocate the cost of each asset to its residual value over its estimated useful life. For assets not amortised on the units-of-production method, amortisation is calculated over their estimated useful life as follows:


•	buildings up to life of mine;


•	plant and machinery up to life of mine;


•	equipment and motor vehicles up to five years;


•	computer equipment up to three years; and


•	leased assets over the shorter of the period of the lease and the useful life of the leased asset.

Major renovations are depreciated over the remaining useful life of the related asset or to the date of the next major renovation, whichever is sooner.

Assets are amortised to residual values. Residual values and useful lives are reviewed, and adjusted if appropriate, at the beginning of each financial year.

Gains and losses on disposals are determined by comparing net sale proceeds with the carrying amount at the date of sale. These are included in the income statement.

Carrying value of goodwill and intangible assets

Where an investment in a subsidiary, joint venture or an associate is made, any excess of the consideration transferred over the fair value of the attributable Mineral Resource including value beyond proved and probable Ore Reserve, exploration properties and net assets is recognised as goodwill.

Intangible assets that have an indefinite useful life and separately recognised goodwill are not subject to amortisation and are tested annually for impairment and whenever events or changes in circumstance indicate that the carrying amount may not be recoverable. Assets that are subject to amortisation are tested for impairment whenever events or changes in circumstance indicate that the carrying amount may not be recoverable.

An impairment loss is recognised for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less costs to sell and value in use. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (cash-generating units).

An individual operating mine is not a typical going-concern business 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 reporting unit. In accordance with the provisions of IAS 36, the group performs its annual impairment review of assigned goodwill during the fourth quarter of each year.

Income taxes and taxation

Income taxes

The group is subject to income taxes in numerous jurisdictions. Significant judgement is required in determining the worldwide provision 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 tax reconciliation between tax expense and the product of accounting profit multiplied by the applicable tax rate, prepared in accordance with IAS 12 Income Taxes, applies the South African corporate tax rate of 28 percent.

The group recognises the net future tax benefit 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.

Taxation

Deferred taxation is recognised on all qualifying temporary differences at the reporting date between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes.

Deferred tax assets are only recognised to the extent that it is probable that the deductible temporary differences will reverse in the foreseeable future and future taxable profit will be available against which the temporary difference can be utilised.

The carrying amount of deferred tax assets is reviewed at each reporting date.

Deferred tax assets and liabilities are measured at future anticipated tax rates, which have been enacted or substantively enacted at the reporting date.

Current and deferred tax is recognised as income or expense and included in profit or loss for the period, except to the extent that the tax arises from a transaction or event which is recognised, in the same or a different period, in other comprehensive income or directly in equity, or a business combination that is an acquisition.

Current tax is measured on taxable income at the applicable statutory rate enacted or substantively enacted at the reporting date. Interest and penalties, if any, are recognised in the income statement as part of taxation expense.

Provision for environmental rehabilitation obligations, environmental expenditure and decommissioning costs

Provision for environmental rehabilitation obligations

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 decommissioning and restoration obligations in the period in which they are incurred. Future changes to environmental laws and regulations, life of mine estimates, inflation rates, foreign currency exchange rates and discount rates could affect the carrying amount of this provision.

Environmental expenditure

The group has long-term remediation obligations comprising decommissioning and restoration liabilities relating to its past operations which are based on the group’s environmental management plans, in compliance with current environmental and regulatory requirements. Provisions for non-recurring remediation costs are made when there is a present obligation, it is probable that expenditure on remediation work will be required and the cost can be estimated within a reasonable range of possible outcomes. The costs are based on currently available facts, technology expected to be available at the time of the clean-up, laws and regulations presently or virtually certain to be enacted and prior experience in remediation of contaminated sites.

Decommissioning costs

The provision for decommissioning represents the cost that will arise from rectifying damage caused before production commences. Accordingly, a provision and a decommissioning asset is recognised and included within mine infrastructure.

Decommissioning costs are provided at the present value of the expenditures expected to settle the obligation, using estimated cash flows based on current prices. The unwinding of the decommissioning obligation is included in the income statement. Estimated future costs of decommissioning obligations are reviewed regularly and adjusted as appropriate for new circumstances or changes in law or technology. Changes in estimates are capitalised or reversed against the relevant asset. Estimates are discounted at a pre-tax rate that reflects current market assessments of the time value of money.

Gains or losses from the expected disposal of assets are not taken into account when determining the provision.

Restoration costs

The provision for restoration represents the cost of restoring site damage after the start of production. Changes in the provision are recorded in the income statement as a cost of production.

Restoration costs are estimated at the present value of the expenditures expected to settle the obligation, using estimated cash flows based on current prices and adjusted for risks specific to the liability. The estimates are discounted at a pre-tax rate that reflects current market assessments of the time value of money.

Stockpiles and metals in process and inventories

Stockpiles and metals in process

Costs that are incurred in or benefit the production process are accumulated in stockpiles and metals in process values. Net realisable value tests are performed at least annually and represent the estimated future sales price of the product, based on prevailing and long-term metals prices, less estimated costs to complete production and bring the product to sale.

Surface and underground stockpiles and metals in process are measured by estimating the number of tonnes added and removed from the stockpile, the number of contained ounces based on assay data, and the estimated recovery percentage based on the expected processing method. Stockpile ore 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 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.

Inventories

Inventories are valued at the lower of cost and net realisable value after appropriate allowances for redundant and obsolete items. Cost is determined on the following bases:


•	metals in process are valued at the average total production cost at the relevant stage of production;


•	gold doré/bullion is valued on an average total production cost method;


•	ore stockpiles are valued at the average moving cost of mining and stockpiling the ore. Stockpiles are classified as a non-current asset where the stockpile exceeds current processing capacity;


•	by-products, which include uranium oxide, silver and sulphuric acid, are valued using an average total production cost method;


•	mine operating supplies are valued at average cost; and


•	heap leach pad materials are measured on an average total production cost basis.

A portion of the related depreciation, depletion and amortisation charge is included in the cost of inventory. Impairments resulting from a decrease in prices are disclosed in other expenses, all other impairments are included in cost of sales

Recoverable tax, rebates, levies and duties

In a number of countries, particularly in Continental Africa, AngloGold Ashanti is due refunds of indirect tax which remain outstanding for periods longer than those provided for in the respective statutes.

In addition, AngloGold Ashanti has unresolved non-income tax disputes in a number of countries, particularly in Continental Africa and in Brazil and Argentina. If the outstanding input taxes are not received and these disputes are not resolved in a manner favourable to AngloGold Ashanti, it could have a material adverse effect upon the carrying value of these assets and our results of operations.

Post-retirement obligations

The determination of AngloGold Ashanti’s obligations and expense for post-retirement liabilities depends on the selection of certain assumptions used by actuaries to calculate amounts. These assumptions include, among others, the discount rate, the expected long-term rate of return of plan assets, health care inflation costs, rates of increase in compensation costs and the number of employees who reach retirement age before the mine reaches the end of its life. While AngloGold Ashanti believes that these assumptions are appropriate, significant changes in the assumptions may materially affect post-retirement obligations as well as future expenses, which may result in an impact on earnings in the periods that the changes in these assumptions occur.

Other post-employment benefit obligations

Some group companies provide post-retirement health care benefits to their retirees. The entitlement to these benefits is usually conditional on the employee remaining in service up to retirement age and completion of a minimum service period. The expected costs of these benefits are accrued over the period of employment using an accounting methodology on the same basis as that used for defined benefit pension plans. Actuarial gains and losses arising from experience adjustments and changes in actuarial assumptions are recorded in other comprehensive income immediately. These obligations are valued annually by independent qualified actuaries.

Ore reserve estimates

Ore Reserve estimates

An Ore Reserve estimate is an estimate of the amount of product that can be economically and legally extracted from the group’s properties. In order to calculate the Ore Reserve, estimates and assumptions are required about a range of geological, technical and economic factors, including quantities, grades, production techniques, recovery rates, production costs, transport costs, commodity demand, commodity prices and exchange rates.

Estimating the quantity and/or grade of the Ore Reserve requires the size, shape and depth of orebodies to be determined by analysing geological data such as the logging and assaying of drill samples. This process may require complex and difficult geological judgements and calculations to interpret the data.

The group is required to determine and report its Ore Reserve in accordance with the minimum standards described by the South African Code for the reporting of Exploration Results, Mineral Resources and Mineral Reserves (The SAMREC Code, 2016 Edition).

Because the economic assumptions used to estimate changes in the Ore Reserve from period to period, and because additional geological data is generated during the course of operations, estimates of the Ore Reserve may change from period to period. Changes in the reported Ore Reserve may affect the group’s financial results and financial position in a number of ways, including the following:


•	asset carrying values may be affected due to changes in estimated future cash flows;


•	depreciation, depletion and amortisation charged in the income statement may change where such charges are determined by the units-of-production method, or where the useful economic lives of assets change;


•	overburden removal costs, including production stripping activities, recorded on the statement of financial position or charged in the income statement may change due to changes in stripping ratios or the units-of-production method of depreciation;


•	decommissioning site restoration and environmental provisions may change where changes in the estimated Ore Reserve 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.

Development expenditure

Development activities commence after project sanctioning by the appropriate level of management. Judgement is applied by management in determining when a project has reached a stage at which economically recoverable reserves exist such that development may be sanctioned. In exercising this judgement, management is required to make certain estimates and assumptions similar to those described in the accounting policy for exploration and evaluation assets. Any such estimates and assumptions may change as new information becomes available. If, after having started the development activity, a judgement is made that a development asset is impaired, the appropriate amount will be written off to the income statement.

Provision for silicosis

Significant judgement is applied in estimating the costs that will be incurred to settle the silicosis class action claims and related expenditure. The final costs may differ from current cost estimates. The provision is based on actuarial assumptions including:


•	silicosis prevalence rates;


•	estimated settlement per claimant;


•	benefit take-up rates;


•	disease progression rates;


•	timing of cashflows; and


•	discount rate.

Management believes the assumptions are appropriate, however changes in the assumptions may materially affect the provision and final costs of settlement.

Identification and classification of discontinued operations

During 2019, the decision to sell the remaining South African operations was made. Judgement was applied regarding classification of the disposal group as held for sale at year end, and whether the disposal group should be classified as a discontinued operation. The South African asset sale was assessed as a major geographical area of operations and part of a single co-ordinated plan to dispose of a major geographical area of operations and accordingly, it was classified as a discontinued operation. The sale was announced on 12 February 2020.

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 in the amount of the best estimate for 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 loss 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.

In determining the threshold for disclosure on a qualitative and quantitative basis, management considers the potential for a disruptive effect on the normal functioning of the group and/or whether the contingency could impact investment decisions. Such qualitative matters considered are reputational risks, regulatory compliance issues and reasonable investor considerations. For quantitative purposes, amateriality threshold of $18m has been applied.

As a global company, the group is exposed to numerous legal risks. The outcome of currently pending and future proceedings cannot be predicted with certainty. Litigation and other judicial proceedings as a rule raise difficult and complex legal issues and are subject to uncertainties and complexities including, but not limited to, the facts and circumstances of each particular case, issues regarding the jurisdiction in which each suit is brought and differences in applicable law. Upon resolution of any pending legal matter, the group may be forced to incur charges in excess of the presently established provisions and related insurance coverage. It is possible that the financial position, results of operations or cash flows of the group could be materially affected by the unfavourable outcome of litigation.

Joint ventures

A joint venture is an entity in which the group holds a long-term interest and which the group and one or more other ventures jointly control under a contractual arrangement, that provides for strategic, financial and operating policy decisions relating to the activities requiring unanimous consent of the parties sharing control. The group’s interests in joint arrangements classified as joint ventures are accounted for using the equity method.

Profits and losses realised in connection with transactions between the group and joint ventures are eliminated in proportion to share ownership. Such profits and losses are deducted from the group’s equity and related statement of financial position amount and released in the group accounts when the assets are effectively realised outside the group. Dividends received from joint ventures are included in operating activities in the cash flow statement.

Associates

The equity method of accounting is used for investments over which the group exercises significant influence and normally owns between 20% and 50% of the voting equity. Associates are equity-accounted from the effective date of acquisition to the effective date of disposal.

Profits and losses realised in connection with transactions between the group and associated companies are eliminated in proportion to share ownership. Such profits and losses are deducted from the group’s equity and related statement of financial position amount and released in the group accounts when the assets are effectively realised outside the group. Dividends received from associates are included in investing activities in the cash flow statement.

Joint ventures and associates

If necessary, impairment losses on loans and equity are reported under share of joint ventures and associates profit and loss.

Any losses of equity-accounted investments are accounted for in the consolidated financial statements until the investment in such investments is written down to zero. Thereafter, losses are accounted for only insofar as the group is committed to providing financial support to such investees.

The carrying value of equity-accounted investments represents the cost of each investment, including goodwill, balance outstanding on loans advanced if the loan forms part of the net investment in the investee, any impairment losses recognised, the share of post-acquisition retained earnings and losses, and any other movements in reserves. The carrying value of equity-accounted investments is reviewed when indicators arise and if any impairment in value has occurred; it is recognised in the period in which the impairment arose.

In determining materiality for the disclosure requirements of IFRS 12 “Disclosure of Interest in Other Entities”, management has assessed that amounts representing the carrying value of at least 90% of the investments in associates and joint ventures balances, reported in the statement of financial position, constitute quantitative materiality.

Unincorporated joint venture - joint operations

Unincorporated joint ventures – 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.

Functional currency

Items included in the financial statements of each of the group’s entities are measured using the currency of the primary economic environment in which the entity operates (the ‘functional currency’). The functional currency of the parent company is South African Rands.

Transactions and balances and group companies

Transactions and balances

Foreign currency transactions are translated into the functional currency using the approximate exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of foreign currency transactions and from the translation at the reporting period exchange rate of monetary assets and liabilities denominated in foreign currencies are recognised in the income statement.

Group companies

The results and financial position of all 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:

•share capital and premium are translated at historical rates of exchange at the reporting date;

•retained earnings are converted at historical average exchange rates;

•assets and liabilities for each statement of financial position presented are translated at the closing rate at the date of that statement of financial position;

•income and expenses for each income statement presented are translated at monthly average exchange rates (unless this average is not a reasonable approximation of the cumulative effect of the rates prevailing on the transaction dates, in which case income and expenses are translated at the rates prevailing at the date of the transaction); and

•all resulting exchange differences are recognised in other comprehensive income and presented as a separate component of equity (foreign currency translation reserve, or FCTR).

Exchange differences arising from the translation of the net investment in foreign operations, and of borrowings and other currency instruments designated as hedges of such investments, are accounted for as other comprehensive income on consolidation. On repayment or realisation, permanent loans and investments are recycled from FCTR to the income statement.

Segment reporting

An operating segment is a business activity whose results are regularly reviewed by the chief operating decision maker (CODM) in order to make decisions about resources to be allocated to it and to assess its performance and for which discrete financial information is available. The chief executive officer and the executive committee are collectively identified as the CODM.

Mine development costs

Capitalised mine development costs include expenditure incurred to develop new orebodies, to define further mineralisation in existing orebodies and to expand the capacity of a mine. Mine development costs include acquired proved and probable Ore Reserve at cost at the acquisition date. These costs are amortised from the date on which commercial production begins.

Depreciation, depletion and amortisation of mine development costs are computed by the units-of-production method based on estimated proved and probable Ore Reserve. The proved and probable Ore Reserve reflects estimated quantities of reserves which can be recovered economically in the future from known mineral deposits.

Capitalised mine development costs also include stripping activity assets relating to production stripping activities incurred in the production phase of open-pit operations of the group. Once determined that any portion of the production stripping costs should be capitalised, the group determines the average mine costs per tonne of the component and the waste tonnes to which the production stripping costs relate to determine the amount of the production stripping costs that should be capitalised. Stripping activity assets are amortised on a units-of-production method based on the Ore Reserve of the component of the orebody to which these assets relate.

The average mine cost per tonne of the component is calculated as the total expected costs to be incurred to mine the relevant component of the orebody, divided by the number of tonnes expected to be mined from the component. The average mine cost per tonne of the component to which the stripping activity asset relates are recalculated annually in the light of additional knowledge and changes in estimates.

Mining infrastructure

Mine infrastructure

Mine plant facilities, including decommissioning assets, are amortised using the lesser of their useful life or units-of-production method based on estimated proved and probable Ore Reserve.

Land and assets under construction

Land and assets under construction are not depreciated and are measured at historical cost less impairments.

Mineral rights and dumps

Mineral rights are amortised using the units-of-production method based on the estimated proved and probable Ore Reserve. Dumps are amortised over the period of treatment.

Exploration and evaluation assets

All pre-license and exploration costs, including geological and geographical costs, labour, Mineral Resource and exploratory drilling cost, are expensed as incurred, until it is concluded that a future economic benefit will more likely than not be realised. In evaluating if expenditures meet this criterion to be capitalised, several different sources of information are used depending on the level of exploration. While the criterion for concluding that expenditure should be capitalised is always probable, the information used to make that determination depends on the level of exploration:


•	Costs on greenfields sites, being those where the group does not have any mineral deposits which are already being mined or developed under the planned method of extraction, are expensed as incurred until the group is able to demonstrate that future economic benefits are probable, which generally will be the establishment of proved and probable Ore Reserve at this location;

•

Costs on brownfields sites, being those adjacent to mineral deposits which are already being mined or developed under the planned method of extraction, are expensed as incurred until the group is able to demonstrate that future economic benefits are probable, which generally will be the establishment of increased inclusive proved and probable Ore Reserve, after which the expenditure is capitalised as a mine development cost; and


•	Costs relating to extensions of mineral deposits, which are already being mined or developed, including expenditure on the definition of mineralisation of such mineral deposits, are capitalised as a mine development cost.

Costs relating to property acquisitions are capitalised within mine development costs.

Leases

The group assesses whether a contract is or contains a lease at inception of a contract. The group recognises a right-of-use asset and a corresponding lease liability with respect to all lease agreements in which it is the lessee, except for short-term leases (defined as leases with a lease term of 12 months or less) and leases of low value assets. For these leases, the group recognises the lease payments as an operating expense on a straight-line basis over the term of the lease unless another systematic basis is more representative of the time pattern in which economic benefits from the leased asset are consumed. The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted by using the rate implicit in the lease. If this rate cannot be readily determined, the group uses its incremental borrowing rate. The group has applied the IFRS 16 portfolio approach in determining the discount rate for leases. As such a single discount rate has been used for contracts that share similar characteristics. The group has determined that contracts that are denominated in the same currency will use a single discount rate. This rate has been determined using various factors including in-country borrowings as well as other sources of finance. Contracts may contain both lease and non-lease components. The group allocates the consideration in the contract to the lease and non-lease components based on their relative stand-alone prices.

Lease payments included in the measurement of the lease liability comprise:


•	fixed lease payments (including in-substance fixed payments), less any lease incentives;


•	variable lease payments that depend on an index or rate, initially measured using the index or rate at the commencement date;


•	the amount expected to be payable by the lessee under residual value guarantees;


•	the exercise price of purchase options, if the lessee is reasonably certain to exercise the options; and


•	payments of penalties for terminating the lease, if the lease term reflects the exercise of an option to terminate the lease.

The lease liability is presented separately in the consolidated statement of financial position, allocated to non-current and current liabilities.

The lease liability is subsequently measured by increasing the carrying amount to reflect interest on the lease liability (using the effective interest method) and by reducing the carrying amount to reflect the lease payments made.

The group remeasures the lease liability (and makes a corresponding adjustment to the related right-of-use asset) whenever:


•	the lease term has changed or there is a change in the assessment of exercise of a purchase option, in which case the lease liability is remeasured by discounting the revised lease payments using a revised discount rate.


•	the lease payments change due to changes in an index or rate or a change in expected payment under a guaranteed residual value, in which cases the lease liability is remeasured by discounting the revised lease payments using the initial discount rate (unless the lease payments change is due to a change in a floating interest rate, in which case a revised discount rate is used).


•	a lease contract is modified and the lease modification is not accounted for as a separate lease, in which case the lease liability is remeasured by discounting the revised lease payments using a revised discount rate.

The right-of-use assets comprise the initial measurement of the corresponding lease liability, lease payments made at or before the commencement day, any initial direct costs and restoration costs as described below. They are subsequently measured at cost less accumulated depreciation and impairment losses.

The lease term is determined as the non-cancellable period of a lease, together with:


•	Periods covered by an option to extend the lease if AngloGold Ashanti is reasonably certain to make use of that option; and / or


•	Periods covered by an option to terminate the lease, if AngloGold Ashanti is reasonably certain not to make use of that option.

Whenever the group incurs an obligation for costs to dismantle and remove a leased asset, restore the site on which it is located or restore the underlying asset to the condition required by the terms and conditions of the lease, a provision is recognised and measured under IAS 37 Provisions, Contingent Liabilities and Contingent Assets. The costs are included in the related right-of-use asset, unless those costs are incurred to produce inventories.

Right-of-use assets are depreciated over the shorter period of lease term and useful life of the underlying asset. If a lease transfers ownership of the underlying asset or the cost of the right-of-use asset reflects that the group expects to exercise a purchase option, the related right-of-use asset is depreciated over the useful life of the underlying asset. The depreciation starts at the commencement date of the lease.

The right-of-use assets are presented as a separate line in the consolidated statement of financial position.

The group applies IAS 36 Impairment of Assets to determine whether a right-of-use asset is impaired and accounts for any identified impairment loss accordingly.

Non-current assets held for sale and discontinued operations

Non-current assets and disposal groups are classified as held for sale if their carrying amount will be recovered principally through a sale transaction rather than through continuing use. This condition is regarded as having been met only when the sale is highly probable and the asset (or disposal group) is available for immediate sale in its present condition. Management must be committed to the sale, which should be expected to qualify for recognition as a completed sale within one year from the date of classification.

Non-current assets (and disposal groups) classified as held for sale are measured at the lower of their previous carrying amount and fair value less costs to sell.

Tangible assets, right of use assets and intangible assets are not depreciated once classified as held for sale.

A disposal group qualifies as a discontinued operation if it is a component of an entity that either has been disposed of, or is classified as held for sale, and:

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

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

•Is a subsidiary acquired exclusively with a view to resale.

Discontinued operations are excluded from the results of continuing operations and are presented as a single amount as profit or loss after tax from discontinued operations in the statement of profit or loss.

Provisions

Provisions are recognised when the group has a present obligation, whether legal or constructive, because of a past event for which 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. Where some or all of the expenditure required to settle a provision is expected to be reimbursed by another party, the reimbursement is recognised only when the reimbursement is virtually certain. The amount to be reimbursed is recognised as a separate asset. Where the group has a joint and several liability with one or more other parties, no provision is recognised to the extent that those other parties are expected to settle part or all of the obligation.

Provisions are measured at the present value of management’s best estimate of the expenditure required to settle the obligation at the reporting date. The discount rate used to determine the present value reflects current market assessments of the time value of money and the risks specific to the liability.

Litigation and administrative proceedings are evaluated on a case-by-case basis considering the information available, including that of legal counsel, to assess potential outcomes. Where it is considered probable that an obligation will result in an outflow of resources, a provision is recorded for the present value of the expected cash outflows if these are reasonably measurable. These provisions cover the estimated payments to plaintiffs, court fees and the cost of potential settlements.

Termination benefits

Termination benefits are payable when employment is terminated before the normal retirement date, or when an employee accepts voluntary redundancy in exchange for these benefits. The group recognises a liability and expense for termination benefits at the earlier of the following dates: (a) when the entity can no longer withdraw the offer of those benefits; and (b) when the entity recognises costs for a restructuring that is within the scope of IAS 37 Provisions, Contingent Liabilities and Contingent Assets and involves the payment of termination benefits. The group recognises termination benefits when it is demonstrably committed to either terminating the employment of current employees according to a detailed formal plan without possibility of withdrawal; or providing termination benefits as a result of an offer made to encourage voluntary redundancy based on the number of employees expected to accept the offer. Benefits falling due more than 12 months after reporting date are discounted to present value.

Share-based payments

The group’s management awards certain employee bonuses in the form of equity-settled share-based payments on a discretionary basis.

The fair value of the equity instruments granted is calculated at grant date. For transactions with employees, fair value is based on market prices of the equity instruments granted, if available, taking into account the terms and conditions upon which those equity instruments were granted. If market prices of the equity instruments granted are not available, the fair value of the equity instruments granted is estimated using an appropriate valuation model. Vesting conditions, other than market conditions, are not taken into account when estimating the fair value of shares or share options at measurement date.

Over the vesting period, the fair value at measurement date is recognised as an employee benefit expense with a corresponding increase in other capital reserves based on the group’s estimate of the number of instruments that will eventually vest. The income statement charge or credit for a period represents the movement in cumulative expense recognised as at the beginning and end of that period. Vesting assumptions for non-market conditions are reviewed at each reporting date to ensure they reflect current expectations.

When options are exercised or share awards vest, the proceeds received, net of any directly attributable transaction costs, are credited to share capital (nominal value) and share premium.

Where the terms of an equity settled award are modified, as a minimum, an 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 employee, as measured at the date of the modification.

In addition, the group’s management awards certain employee bonuses in the form of a cash settled scheme, whereby awards granted are linked to the performance of the company’s share price. A liability is recognised based upon the grant date fair value and is subsequently remeasured to the closing share price at each reporting date up to the date of vesting. Remeasurements to fair value are recognised in the income statement.

Revenue recognition

Revenue is recognised when control of the goods passes to the customer and the performance obligations of transferring control have been met. The amount of revenue recognised reflects the consideration to which the entity is entitled in exchange for the goods transferred.

Revenue from product sales comprises sales of:


•	refined gold;


•	by-products including silver and sulphuric acid; and


•	doré bars.

Revenue from product sales is recognised at a point in time.

Operating expense and income

Other expenses and income

Items of income and expense, not included in gross profit, that are:


•	material either quantitatively or qualitatively, or both;


•	non-recurring;


•	not directly related to current operating or financing activities ; and


•	not disclosed separately on the face of the income statement,

are classified as Other expenses and income on the face of the income statement.

Financial instruments

Financial instruments are initially recognised at fair value when the group becomes a party to their contractual arrangements. Transaction costs directly attributable to the instrument’s acquisition or issue are included in the initial measurement of financial assets and financial liabilities, except financial instruments classified as at fair value through profit or loss (FVTPL). The subsequent measurement of financial instruments is dealt with below.

Financial liabilities

Financial liabilities are classified as measured at amortised cost.

A financial liability is derecognised when the obligation under the liability is discharged, cancelled or expires. The group also derecognises a financial liability when its terms are modified and the cash flows of the modified liability are substantially different. In this case a new financial liability based on the modified terms is recognised at fair value.

Financial assets

On initial recognition, a financial asset is classified as measured at:

•amortised cost;

•Fair value through other comprehensive income (FVTOCI) - equity instruments; or

•FVTPL.

At initial recognition, the group measures a financial asset at its fair value plus, in the case of a financial asset not at FVTPL, transaction costs that are directly attributable to the acquisition of the financial asset. Transaction costs of financial assets carried at FVTPL, are expensed.

A financial asset is measured at amortised cost if it is held within the business model whose objective is to hold assets to collect contractual cash flows and its contractual terms give rise, on specified dates, to cash flows that are solely payments of principal and interest on the principal amount outstanding. Interest income from these financial assets is included in finance income using the effective interest rate method. Any gain or loss arising on derecognition is recognised directly in profit or loss and presented in other gains or losses, together with foreign exchange gains or losses. Impairment losses are presented in the statement of profit or loss. A gain or loss on a debt investment that is subsequently measured at FVTPL is recognised in profit or loss and presented net within other gains or losses in the period in which it arises. On derecognition of a financial asset, the difference between the proceeds received or receivable and the carrying amount of the asset is included in profit or loss.

Equity instruments

Listed equity investments which are held to meet rehabilitation liabilities are classified as FVTPL. Listed equity investments held for other purposes are classified as FVTOCI.

The group subsequently measures all equity investments at fair value. Where the group’s management has elected to present fair value gains and losses on equity investments in OCI, there is no subsequent reclassification of fair value gains and losses to profit or loss following the derecognition of the investment. Dividends from such investments continue to be recognised in profit or loss as other income when the group’s right to receive payments is established. Residual values in OCI are reclassified to retained earnings (accumulated losses) on derecognition of the related FVTOCI instruments. Changes in the fair value of financial assets at FVTPL are recognised in other gains or losses in the statement of profit or loss as applicable.

Trade receivables

Trade receivables mainly comprise receivables owing from banking institutions purchasing gold bullion. Normal market settlement terms are two working days.

Impairment of financial assets

Financial assets at amortised cost consist of trade receivables, loans, cash and cash equivalents and debt instruments. Impairment losses are assessed using the forward-looking expected credit loss (ECL) approach. An allowance is recorded for all loans and other debt financial assets not held at FVTPL. The impairment methodology applied depends on whether there has been a significant increase in credit risk. Trade receivable loss allowances are measured at an amount equal to lifetime ECL’s. Loss allowances are deducted from the gross carrying amount of the assets. Debt securities that are determined to have a low credit risk at the reporting date and bank balances, for which credit risk has not increased significantly since initial recognition, are measured at an amount equal to 12-month ECL.

Fair value measurements

The group measures financial instruments at fair value at each reporting date where relevant. Fair value is 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. The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing the asset or liability, assuming that market participants act in their economic best interest.

For the purpose of fair value disclosures, the group has determined classes of assets and liabilities on the basis of the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy. The group uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximising the use of relevant observable inputs and minimising the use of unobservable inputs.
