Glossary of terms, abbreviations and useful definitions
Adjusted gross profit (loss): Gross profit (loss) excluding unrealised non-hedge derivatives and other commodity contracts.
Adjusted headline earnings (loss): Headline earnings (loss) excluding unrealised non-hedge derivatives, fair value adjustments on the mandatory convertible bonds and the option component of the convertible bonds, adjustments to other commodity contracts and deferred tax thereon.
All injury frequency rate: The total number of injuries and fatalities that occurs per million hours worked.
All-in costs: All-in costs are all-in sustaining costs plus additional non-sustaining costs which reflect the varying costs of producing gold over the life-cycle of a mine. Non-sustaining costs are those costs incurred at new operations and costs related to ‘major projects’ at existing operations where these projects will materially increase production.
All-in costs in dollars per ounce is arrived at by dividing the dollar value of the sum of these cost metrics by the ounces of gold sold.
All-in sustaining costs: During June 2013 the World Gold Council (WGC), an industry body, published a Guidance Note on “all-in sustaining costs” metric, which gold mining companies can use to supplement their overall non-GAAP disclosure. “All-in sustaining costs” is an extension of the existing “cash cost” metric and incorporates all costs related to sustaining production and in particular recognising the sustaining capital expenditure associated with developing and maintaining gold mines. In addition, this metric associated with developing and maintaining gold mines. In addition, this metric includes the cost associated with corporate office structures that support these operations, the community and rehabilitation costs attendant with responsible mining and any exploration and evaluation costs associated with sustaining current operations. All-in sustaining $/oz is arrived at by dividing the dollar value of the sum of these cost metrics, by the ounces of gold sold.
By-products: Any products that emanate from the core process of producing gold, including silver, uranium and sulphuric acid.
Capital expenditure: Total capital expenditure on tangible and intangible assets which includes stay-in-business and project capital.
Adjusted EBITDA: Operating profit (loss) before amortisation of tangible and intangible assets, retrenchment costs at the operations, impairment and derecognition of goodwill, tangible and intangible assets, impairment of investments, profit (loss) on disposal and derecognition of assets and investments, gain (loss) on unrealised non-hedge derivatives and other commodity contracts, write-off of stockpile and heap leach inventories to net realisable value plus the share of associates’ EBITDA, less profit (loss) from discontinued operations.
The adjusted EBITDA calculation is based on the formula included in the revolving credit agreements for compliance with the debt covenant formula as specified in the revolving credit agreements.
Effective tax rate: Current and deferred taxation as a percentage of profit before taxation.
Equity: Total equity plus the mandatory convertible bonds. Where average equity is referred to, this is calculated by averaging the figures at the beginning and the end of the financial year.
Gain (loss) on non-hedge derivatives and other commodity contracts: Fair value changes on derivatives that are neither designated as meeting the normal sale exemption under IAS 39, nor designated as cash flow hedges and other commodity contracts.
Gold produced: Refined gold in a saleable form derived from the mining process.
Net debt: Borrowings (excluding the Turbine Square Two (Proprietary) Limited lease and the mandatory convertible bonds; adjusted for the unamortised portion of the convertible and rated bonds; and the fair value adjustment on the $1.25bn bond) less cash.
Net capital employed: Total equity adjusted for other comprehensive income, actuarial gain (loss) and deferred taxation plus interest-bearing borrowings, less cash and cash equivalents and adjusted for capital expenditure incurred on assets not yet in production. Where average net capital employed is referred to, this is the average of the figures at the beginning and the end of the financial year.
Net operating assets: Tangible assets, current and noncurrent portion of inventories, current and non-current trade and other receivables (excluding recoverable tax, rebates, levies and duties), less current and non-current trade, other payables and deferred income (excluding unearned premiums on normal sale extended contracts).
Operating cash flow: Net cash inflow from operating activities less stay-in-business capital expenditure.
Productivity: An expression of labour productivity based on the ratio of ounces of gold produced per month to the total number of employees in mining operations.
Project capital: Capital expenditure to either bring a new operation into production; to materially increase production capacity; or to materially extend the productive life of an asset.
Region: Defines the operational management divisions within AngloGold Ashanti Limited, namely South Africa, Continental Africa (Democratic Republic of the Congo, Ghana, Guinea, Mali, Namibia and Tanzania), Australasia (Australia and surrounding areas), and the Americas (Argentina, Brazil and United States of America).
Rehabilitation: The process of reclaiming land disturbed by mining to allow an appropriate post-mining use. Rehabilitation standards are defined by country-specific laws, including but not limited to the South African Department of Mineral Resources, the US Bureau of Land Management, the US Forest Service, and the relevant Australian mining authorities, and address among other issues, ground and surface water, topsoil, final slope gradient, waste handling and re-vegetation issues.
Return on equity: Adjusted headline earnings before finance costs on the mandatory convertible bonds and hedge buyback costs expressed as a percentage of average equity.
Stay-in-business capital: Capital expenditure to extend useful lives of existing production assets. This includes replacement of vehicles, plant and machinery, Ore Reserve development, deferred stripping and capital expenditure related to financial benefit initiatives, safety, health and the environment.
Stripping ratio: The ratio of waste tonnes to ore tonnes mined calculated as total tonnes mined less ore tonnes mined divided by ore tonnes mined.
Sustaining capital: Total capital expenditure less any capital expenditure that relates to project capital expenditure and new investment/projects at all of our mines, whether they are in production or development stage.
Total cash costs: Total cash costs include site costs for all mining, processing and administration, reduced by contributions from by-products and are inclusive of royalties and production taxes. Amortisation, rehabilitation, corporate administration, retrenchment, capital and exploration costs are excluded. Total cash costs per ounce are the attributable total cash costs divided by the attributable ounces of gold produced.
Total employee costed: This takes account of all employees and contractors directly employed in and associated with the production process.
Weighted average number of ordinary shares: The number of ordinary shares in issue at the beginning of the year, increased by shares issued during the year, weighted on a time basis for the period during which they have participated in the income of the group, and increased by share options that are virtually certain to be exercised.
