Annual report suite 2012

Summarised financial information

The summarised consolidated results were approved on 19 March 2013 by the AngloGold Ashanti’s board of directors and were signed on their behalf by the Chairman, Tito Mboweni, Chief Executive Officer, Mark Cutifani, and Chief Financial Officer, Srinivasan Venkatakrishnan.

This section is provided as a summary of the information contained in AngloGold Ashanti’s annual financial statements. The summarised consolidated financial results are not the group’s statutory accounts and do not contain sufficient information to allow for a complete understanding of the results and state of affairs of the group, as would be provided by the detailed annual financial statements. Should you wish to obtain a hard copy of the annual financial statements, please contact in this regard.

Basis of preparation

The summarised consolidated financial results for the year ended 31 December 2012 have been prepared in accordance with International Accounting Standard 34 Interim Financial Reporting, Listings Requirements of the JSE Limited, Financial Reporting Guides as issued by the South African Institute of Chartered Accountants and the South African Companies Act, 2008, as amended.

The accounting policies applied in the presentation of the summarised financial results are consistent with those applied for the year ended 31 December 2011 and in terms of International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board, except as follows:

Standard or interpretation Title Effective for annual periods
beginning on or after
IAS 12 Amendment – Deferred tax: Recovery of Underlying Assets 1 January 2012

The adoption of this amendment did not have any effect on the financial position, results or disclosures of the group.

In addition, effective 1 January 2012, the group changed the presentation currency of its results from reporting in US dollars and South African Rands to reporting only in US dollars. Management has concluded that the change in presentation currency will result in more relevant information than the previous position of reporting in two currencies. The change in presentation currency has no effect on comparative information.

These summarised consolidated financial results do not include all the information required for complete annual financial statements prepared in accordance with IFRS, and have been prepared according to the historical cost accounting convention, except for the revaluation of certain financial instruments to fair value. The group’s accounting policies are consistent in all material respects with those applied in the previous year, except for the adoption of the new and revised standards and interpretations mentioned above and the change in presentation currency.

The summarised consolidated results have been prepared by the corporate reporting staff of AngloGold Ashanti Limited, headed by John Edwin Staples, the group’s Chief Accounting Officer. This process was supervised by Mark Cutifani, the group’s Chief Executive Officer and Srinivasan Venkatakrishnan, the group’s Chief Financial Officer.

Related party transactions

The group, in the ordinary course of business, entered into various sale and purchase transactions with related parties.

Significant changes in contingent liabilities since 31 December 2011

AngloGold Ashanti Colombia S.A. (AGAC) received notice from the Colombian Tax Office (DIAN) that it disagreed with the company’s tax treatment of certain items in the 2011 and 2010 income tax returns. The company believes that the tax legislation has been correctly applied. The company is considering defending AGAC’s position. An estimated additional tax of $26m will be payable if the tax returns are amended. Penalties and interest for the additional tax are expected to be $135m based on Colombian tax law.

Independent audit by the auditors

These summarised consolidated financial results for the year ended 31 December 2012 have been extracted from the complete set of annual financial statements on which the auditors, Ernst & Young Inc. has expressed an unqualified audit opinion. Ernst & Young Inc. has also issued an unqualified audit opinion on these summarised financial statements, stating that these summarised results are consistent in all material respects with the complete annual financial statements. The auditor’s opinion and annual financial statements, which have been summarised in this report, are available for inspection at the registered office of the company.

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 the Ore Reserve as the basis of future cash flow estimates and unit-of-production depreciation, depletion and amortisation calculations; environmental, reclamation and closure obligations; estimates of recoverable gold and other materials in heap leach pads; asset impairments/reversals (including impairments of goodwill); and write-downs of inventory to net realisable value; post-employment, post-retirement and other employee benefit liabilities; and deferred taxation.

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

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. Thus, an adverse decision in a lawsuit could result in additional costs that are not covered, either wholly or partly, under insurance policies and that could significantly influence the business and results of operations.

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 goodwill and tangible assets

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

For mobile and other equipment, 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 the Proved and Probable Ore Reserve. This would generally arise when there are significant changes in any of the factors or assumptions used in estimating Ore Reserve.

These factors could include:

  • changes in the Proved and Probable Ore Reserve;
  • the grade of the Ore Reserve may vary significantly from time to time;
  • 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 exchange rates; and
  • changes in Ore Reserve could similarly impact the useful lives of assets amortised on a straight-line basis where those lives are limited to the life of the mine.

The recoverable amounts of cash generating units and individual assets have been determined based on the higher of value in use calculations and fair values less costs to sell. These calculations require the use of estimates and assumptions. It is reasonably possible that the gold price assumption may change which may then impact the estimated life of mine determinant and may then require a material adjustment to the carrying value of goodwill and tangible assets.

The group defers stripping costs incurred during the production stage of its open-pit operations for those operations where this is the most appropriate basis for matching the costs against the related economic benefits. This is generally the case where there are fluctuations in stripping costs over the life of the mine.

In the production stage of some open-pit operations, further development of the mine requires a phase of unusually high overburden removal activity that is similar in nature to preproduction mine development. The costs of such unusually high overburden removal activity are deferred and charged against reported profits in subsequent periods on a units-ofproduction method. This accounting treatment is consistent with that for stripping costs incurred during the development phase of a mine, before production commences.

If the group was to expense production stage stripping costs as incurred, this would result in volatility in the year to year results from open-pit operations and excess stripping costs would be expensed at an earlier stage of a mine’s operation.

Deferred stripping costs are included in ‘Mine development costs’ within tangible assets. These 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 deferred stripping costs is included in operating costs.

The group reviews and tests the carrying value of assets when events or changes in circumstances suggest that the carrying amount may not be recoverable. In addition, goodwill is tested on an annual basis for impairment. Assets are grouped at the lowest level for which identifiable cash flows are largely independent of cash flows of other assets. 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. The cash flows and value in use are significantly affected by a number of factors including the published Ore Reserve, Mineral Resource, exploration potential and production estimates, together with economic factors such as spot and future gold prices, discount rates, foreign currency exchange rates, estimates of costs to produce the Ore Reserve and future capital expenditure.

An individual operating mine is not a typical going-concern business because of the finite life of its Ore Reserve. 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 “Impairment of Assets”, the group performs its annual impairment review of assigned goodwill during the fourth quarter of each year.

The carrying amount of goodwill in the consolidated financial statements at 31 December 2012 was $195m (2011: $179m). The carrying amount of tangible assets at 31 December 2012 was $7,648m (2011: $6,525m).

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 by the unique nature of each mine construction project and include factors such as the complexity of a plant and its location. The group considers various relevant criteria to assess when the mine is substantially complete and 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;
  • completion of a reasonable period of testing of the mine plant and equipment;
  • ability to produce gold in saleable form (within specifications and the de minimis rule); and
  • ability to sustain ongoing production of gold.

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 or Ore Reserve development.

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. Actual costs incurred in future periods could differ materially from the estimates. Additionally, future changes to environmental laws and regulations, life of mine estimates, foreign currency exchange rates and discount rates could affect the carrying amount of this provision.

The carrying amount of the rehabilitation obligations for the group at 31 December 2012 was $841m (2011: $747m).

Stockpiles, metals in process and ore on leach pad

Costs that are incurred in or benefit the production process are accumulated as stockpiles, metals in process and ore on leach pads. 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.

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

Estimates of the recoverable gold on the leach pads are calculated from the quantities of ore placed on the pads based on measured tonnes added to the leach pads, the grade of ore placed on the leach pads based on assay data and a recovery percentage based on metallurgical testing and ore type.

Although the quantities of recoverable metal are reconciled by comparing the grades of ore to the quantities of gold 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.

The carrying amount of inventories (excluding finished goods and mine operating supplies) for the group at 31 December 2012 was $1,383m (2011: $1,060m).

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 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 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 Ore Reserve in accordance with the SAMREC code.

Because the economic assumptions used to estimate Ore Reserve change from period to period, and because additional geological data is generated during the course of operations, estimates of Ore Reserve may change from period to period. Changes in 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 basis or where the useful economic lives of assets change;
  • overburden removal costs recorded on the statement of financial position or charged in the income statement may change due to changes in stripping ratios or the units-ofproduction basis of depreciation;
  • decommissioning site restoration and environmental provisions may change where changes in 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.

Exploration and evaluation expenditure

The group’s accounting policy for exploration and evaluation expenditure results in certain items of expenditure being capitalised for an area of interest where it is considered likely to be recoverable by future exploitation. This policy requires management to make certain estimates and assumptions as to future events and circumstances, in particular whether an economically viable extraction operation can be established. Any such estimates and assumptions may change as new information becomes available. If, after having capitalised the expenditure, a judgement is made that recovery of the expenditure is unlikely, the relevant capitalised amount will be written off to the income statement.

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 material exists such that development may be sanctioned. In exercising this judgement, management is required to make certain estimates and assumptions similar to those described above for capitalised exploration and evaluation expenditure. 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.


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.

In determining the threshold for disclosure, on a quantitative and qualitative 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 an amount of $20m, has been considered.

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.
