| 1. Basis
of preparation |
The
financial statements are prepared on the historical cost basis. The
following are the principal accounting policies used by the group
which are in accordance with International Accounting Standards, South
African Generally Accepted Accounting Practice, the South African
Companies Act and are consistent with those of the previous year,
except as set out in paragraph 20.
|
| 2. Consolidation |
The
consolidated financial statements include those of the holding company
and its subsidiaries. Subsidiary undertaking, are those companies
in which the group, directly or indirectly, has an interest of more
than one half of the voting rights or otherwise has power to exercise
control over the operations. Subsidiaries are consolidated from the
date on which effective control is transferred to the group and are
no longer consolidated from date of disposal. Internal profits and
sales are eliminated on consolidation and all sales revenue and profit
figures relate to external transactions only.
Any excess or shortfall of the purchase price over the fair value
of the attributable net assets of subsidiaries at the date of acquisition
is capitalised and amortised over the useful lives of the applicable
underlying assets. (Refer paragraph 8).
|
| |
| 3. Investments
in associates |
Investments
in associated undertakings are accounted for by the equity method
of accounting. These are undertakings in which the group has a long
term interest and over which it exercises significant influence but
not control. Provisions are recorded for long term impairment in values.
Equity accounting involves recognising in the income statement the
group’s share of the associates’ post acquisition profit or loss for
the year. The group’s interest in the associate is carried in the
balance sheet at an amount that reflects its share of the net assets
of the associate and includes any excess or deficit of the purchase
price over the fair value of attributable assets of the associate
at date of acquisition. Any excess or deficit of the purchase price
over the attributable net assets of the associate is amortised over
the useful lives of underlying assets. (Refer paragraph 8).
|
| |
| 4. Foreign
currencies |
Income
statements of foreign entities and associated undertakings are translated
to rand at average exchange rates for the year and the balance sheets
are translated at rates ruling at the balance sheet date. The exchange
difference arising on translation of assets and liabilities, including
the excess or shortfall of the purchase price over a fair value of
attributable net assets at date of acquisition, of foreign subsidiaries
and associates are transferred directly to equity. On disposal of
the foreign entity such translation differences are recognised in
the income statement as part of the gain or loss on sale.
Foreign currency transactions are accounted for at the rates of exchange
ruling at the date of the transaction. Monetary assets and liabilities
are translated at year end exchange rates unless hedged by forward
exchange contracts, in which case the rates specified in such forward
contracts are used. Gains and losses arising on settlement of such
transactions and from the translation of foreign currency monetary
assets and liabilities arising from such transactions are recognised
in the income statement.
Forward exchange contracts are entered into to hedge anticipated future
transactions. These instruments are not recognised in the financial
statements until the settlement date of these transactions as the
purpose of these contracts is to reduce exposure to fluctuation in
foreign currency exchange rates. No provision is made for potential
gains and losses on open contracts.
|
| |
| 5. Commodity
hedging transaction |
Metal
futures, options and lease contracts are entered into to preserve
and enhance future revenue streams. Hedging contracts are not recognised
in the financial statements until settlement date, at which time they
are included in the determination of revenue. No provision is made
for potential gains or losses on open contracts. Non-hedging contracts
are initially recorded at cost with any subsequent changes in their
fair value recorded as a market-to-market adjustment in the income
statement.
|
| |
| 6. Financial
Instruments |
Financial
instruments carried on the balance sheet include cash and bank balances,
money market instruments, investments, receivables, trade creditors,
leases and borrowings.
The group is also party to financial instruments that reduce risk
to foreign currency and future metal price fluctuations which are
not recognised in the financial statements at inception. The particular
recognition methods adopted are disclosed in the individual policy
statements associated with each item.
|
| |
| 7. Investments |
Investments
are stated at cost and are only written down where the directors are
of the opinion that there has been a permanent diminution in value.
Where there has been a permanent diminution in value of an investment,
it is recognised as an expense in the period in which the diminution
is recognised.
On disposal of an investment, the difference between the net disposal
proceeds and the carrying amount is charged or credited to the income
statement.
|
| |
| 8. Property,
plant and equipment |
| • Mining
assets: |
| Mining
assets are recorded at cost. Expenditure, including evaluation costs,
incurred to establish or expand productive capacity, to support and
maintain that productive capacity and net working costs incurred on
mines prior to the commencement of commercial levels of production,
are capitalised to mining assets. Interest on borrowings, specifically
to finance establishment of mining assets, is capitalised until commercial
levels of production are achieved. |
| |
| • Mothballed
mining operations: |
| The
net assets of mothballed operations are written down to net realisable
value. Expenditure on the care and maintenance of these operations
is charged against income, as incurred. |
| |
| • Amortisation: |
| Mining
assets are amortised using the units-of-production method based on
estimated economically recoverable proven and probable ore reserves,
limited to a maximum period of 25 years. |
| |
| • Impairment: |
| The
recoverability of the long-term assets is reviewed by management on
a continuous basis, based on estimates of future net cash flows. These
estimates are subject to risks and uncertainties including future
metal prices and exchange rates. It is therefore reasonably possible
that changes could occur which may affect the recoverability of the
mining assets. Where the value in use is less than the estimated net
book value, the impairment is charged against income to reduce the
carrying value to the recoverable amount of the asset. |
| |
| • Mining
exploration: |
| Expenditure
on mining exploration in new areas of interest is charged against
income as incurred. Costs related to property acquisitions, surface
and mineral rights are capitalised. Where the directors consider that
there is little likelihood of the properties or rights being exploited,
or the value of the exploration rights have diminished below cost,
a write down is effected against exploration expenditure. |
| |
| •
Other fixed assets: |
Other
fixed non-mining assets are recorded at cost. Depreciation is calculated
using rates and bases which are designed to write off the assets over
their expected useful lives. Freehold properties are not depreciated.
|
| 9. Accounting
for leases |
Leases
of property, plant and equipment where the group assumes substantially
all of the benefits and risks of ownership are classified as finance
leases. Finance leases are capitalised at the estimated present value
of the underlying lease payments. Each lease payment is allocated
between the liability and finance charges so as to achieve a constant
rate on the balance outstanding. The corresponding rental obligations,
net of finance charges, are included in other long-term payables.
The interest element is expensed to the income statement, as a finance
charge, over the lease period.
The property, plant and equipment acquired under finance leasing contracts
is amortised in terms of the group accounting policy. (Refer to paragraph
8).
Leases of assets under which all the risks and benefits of ownership
are effectively retained by the lessor are classified as operating
leases. Payments made under operating leases are charged to the income
statement in the period in which they occur.
When an operating lease is terminated before the lease period has
expired, any payment required to be made to the lessor by way of penalty
is recognised as an expense in the period in which termination takes
place.
|
| 10. Inventories |
| • Metal
inventories: |
| Platinum,
palladium and rhodium are treated as main products and other platinum
group- and base metals produced as by-products. Metals mined by the
company, including in-process metal contained in matte produced by
the smelter and precious metal concentrate in the base and precious
metal refineries, are valued at the lower of average cost of production
and estimated net realisable value. Quantities of in-process metals
are based on latest available assays. The average cost of production
is taken as total costs incurred on mining and refining, including
amortisation, less net revenue from by-products. Costs are allocated
to main products on a units produced basis. Refined by-products are
valued at their estimated net realisable value. Stocks of platinum
group metals purchased or recycled by the company are valued at the
lower of cost and estimated net realisable value. |
| |
| • Stores
and materials: |
Stores
and materials are valued at the lower of cost and net realisable value,
on a first-in-first-out basis. Obsolete, redundant and slow moving
stores are identified and written down to economic or realisable values.
|
| 11. Trade
receivables |
Trade
receivables are carried at anticipated realisable value. An estimate
is made for doubtful receivables based on a review of all outstanding
amounts at year end. Bad debts are written off during the year in
which they are identified.
|
| 12. Cash
and cash equivalents |
For
the purposes of the cash flow statement, cash and cash equivalents
comprise cash in hand, deposits held at call with banks, investments
in money market instruments and short term unlisted investments, net
of bank overdrafts. In the balance sheet, bank overdrafts are included
in borrowings under current liabilities.
|
| 13. Provisions |
Provisions
are recognised when the group has a present legal or constructive
obligation as a result of past events where it is probable that an
outflow of resources embodying economic benefits will be required
to settle the obligation, and a reliable estimate of the amount of
the obligation can be made.
|
| 14. Segmental
reporting |
The
group is an integrated pgm and associated base metals producer. On
a primary basis, the business segments are:
| - |
|
|
|
mine-to-market
primary pgm producer, including marketing of metals produced
by the group; |
| - |
|
|
|
mine-to-concentrate
primary pgm producer; |
| - |
|
|
|
toll
refiner of third party material. |
|
| 15. Pension
and other post-retirement obligations |
The
group operates or participates in a number of defined benefit and
defined contribution retirement plans for the group’s employees. The
pension plans are funded by payments from the employees and by the
relevant group companies taking account of the recommendations of
independent qualified actuaries. The assets of the different plans
are held by independently managed trust funds.
These funds are governed by the Pension Fund Act of 1956. Defined
benefit plans such as the Mine Officials Pension Fund and the Mine
Employees Pension Fund are subject to actuarial valuations at intervals
of no more than three years.
These plans are, in substance, accounted for as defined contribution
plans. Contributions to the defined benefit and contribution plans
are therefore charged to income as incurred.
The group provides post-retirement health care benefits to qualifying
retirees. The expected costs of these benefits are accrued over the
period of employment. Valuations of these obligations are carried
out by independent qualified actuaries at intervals of no more than
three years.
|
| 16. Deferred
income taxation |
Deferred
taxation is calculated on a comprehensive basis using the balance
sheet approach. Deferred tax liabilities or assets are recognised
by applying expected corporate tax rates to the temporary differences
existing at each balance sheet date between the tax values of assets
and liabilities and their carrying amounts where such temporary differences
are expected to result in taxable or deductible amounts in determining
taxable profits for future periods when the carrying amount of the
assets or liability is recovered or settled.
The principal temporary differences arise from amortisation and depreciation
on property, plant and equipment, provisions, post-retirement benefits
and tax losses carried forward. Deferred tax assets relating to the
carry forward of unused tax losses are recognised to the extent that
it is probable that future taxable profit will be available against
which the unused tax losses can be utilised.
|
| 17. Environmental
obligations |
| • Rehabilitation
costs: |
The
net present value of future rehabilitation cost estimates are recognised
and provided for in full in the financial statements. The estimates
are reviewed annually to take into account the effects of inflation
and changes in the estimates are discounted using rates that reflect
the time value of money.
Annual increases in the provision are charged to income and are split
between finance costs relating to the change in the present value
of the provision, inflationary increases in the provision and changes
in the estimates. The present value of additional environmental disturbances
created are capitalised to mining assets along with a corresponding
increase in the rehabilitation provision. The rehabilitation asset
is amortised in terms of the group’s accounting policy (Refer paragraph
8). Rehabilitation projects undertaken, included in the estimates,
are charged to the provision as incurred. |
| |
| • Ongoing
rehabilitation cost: |
| The
cost of the ongoing current programmes to prevent and control pollution
is charged against income as incurred. |
| |
| • Impala
Pollution, Rehabilitation and Closure Trust Fund: |
Annual
contributions are made to the group’s trust fund, created in accordance
with statutory requirements, to provide for the estimated cost of
rehabilitation during and at the end of the life of the group’s mines.
Income earned on monies paid to the trust is accounted for as investment
income. The funds contributed to the trust are included under investments.
|
| 18. Revenue
recognition |
Turnover
comprises the rand amount received and receivable from customers in
respect of the supply of metals mined, metals purchased and toll income
received by the group and the net profit and losses arising from hedging
transactions to the extent that they relate to that metal and have
been matched at the date of the financial statements. Revenue is recognised
at the date of dispatch of metal from the refinery, net of sales taxes
and discounts. Toll refining income is recognised at date of declaration
or dispatch of metal from the refinery in accordance with the relevant
agreements with customers and after eliminating sales within the group.
Other revenues earned by the group are recognised on the following
bases:
| • |
|
|
|
Interest
income – as it accrues (taking into account the effective yield
on the asset) unless collectibility is in doubt. |
| • |
|
|
|
Dividend
income – when the shareholder’s right to receive payment is
established, recognised at the last date of registration. |
|
| 19. Comparatives |
Where
necessary, comparative figures have been adjusted to conform with
changes in presentation in the current year.
|
| 20. Changes
in accounting policies |
During
the year, the group adopted the provisions of International Accounting
Standards (IAS) 10 (revised) (Events after the balance sheet date).
Under the revised accounting policy dividends and related secondary
tax on companies (STC) will only be brought to account once dividends
have been declared.
The effect of the change is a R50.0 million increase in attributable
earnings for the year ended 30 June 2000. Opening retained earnings
have been adjusted in the consolidated- and company statements of
changes in equity. |
