Onerous contracts
Onerous contracts are identified through regular reviews of the terms and conditions of contracts as well as on the acquisition of businesses. A provision for
onerous contracts is calculated as the present value of the portion which management deems to be onerous in light of the current market conditions, discounted
using market-related rates. An annual expense is recognised over the life of the contracts.
Insurance liabilities
Insurance liabilities include amounts provided for: unearned premiums, which represent the proportion of premiums written in the current year which relate to
risks that have not expired by the end of the financial year and are calculated on a time proportionate basis; deferred acquisition costs, which are recognised on a
basis consistent with the related provisions for unearned premiums; claims, which are calculated on the settlement amount outstanding at year-end; and claims
incurred but not reported, for claims arising from events that occurred before the close of the accounting period but which had not been reported to the Group by
that date, and are calculated based on the preceding six years’ insurance premium revenue multiplied by percentages specified in the Short-Term Insurance Act.
Dismantling and site restoration
A provision is raised for the estimated costs of dismantling and removing items, and restoring the property on which they are located. The change in the liability
arising as a result of unwinding the discount is recognised in the income statement as a finance charge. The dismantling of the plant and recommissioning of
buildings is expected to coincide with the end of the useful life of the plant and lease periods.
Other
Included in other is a provision raised for the estimated cost of honouring warranties on certain products sold where the manufacture warranty is inadequate or
not available, R40 million (2016: R16 million). Also included is a provision for insurance raised for the estimated cost of claims not covered by the Group’s
insurance policies and in certain instances for the cost of claims below the Group’s inner deductibles, R25 million (2016: R26 million). |
