Other provisions

A provision is recognised when, due to a past event, there is a present legal or constructive obligation that is of an uncertain size or that will occur at an uncertain future date, and where its settlement will probably lead to an outflow of funds.

Provisions that will be settled within one year of the reporting date, or that are of limited material significance, are recognised at face value. Other provisions are recognised at the present value of the expected expenditure. The specific risks inherent to the relevant obligation are taken into account when determining this expenditure. The present value is calculated using a pre-tax discount rate which reflects the current market valuation of the time value of money. The determination of the expected expenditure is based on detailed plans in order to limit the uncertainty regarding the amount.

Decommissioning

A provision is recognised that equals the present value of the expected costs where there is an obligation to dismantle, demolish or remove an item of property, plant or equipment when it ceases to be used. The initial recognition of the decommissioning provision for an asset is included in the cost of that asset. Interest is added periodically to the decommissioning provision.

Onerous contracts

A provision for onerous contracts is recognised when it is probable that the unavoidable costs of meeting the contractual obligations exceed the economic benefits to be derived from the contract.

Restructuring

A restructuring provision is recognised if a detailed plan for the restructuring has been approved and its main features have been announced to those affected by it.
