3.3Property, plant and equipment

Accounting policies

Property, plant and equipment is valued at purchase or manufacturing cost less accumulated depreciation and any impairment in value. Depreciation is calculated on a straight-line basis over the expected useful lifetime of the individual assets or asset categories. Where an asset comprises several parts with different useful lifetimes, each part of the asset is depreciated separately over its applicable useful lifetime.

The applicable useful lifetimes are 25 – 40 years for buildings and 3 – 10 years for production facilities, machinery, equipment, and vehicles. Land is not depreciated. Leasehold improvements are depreciated over the shorter of useful life or lease term.

Subsequent expenditure on an item of tangible assets is capitalized at cost only when it is probable that future economic benefits associated with the item will flow to the Group and the cost of the item can be measured reliably. Expenditure for repair and maintenance, which does not increase the estimated useful lifetimes of the related assets are recognized as an expense in the period in which they are incurred.

The Group assesses at each reporting date, whether there is any indication, that an asset may be impaired. If any such indication exists, the recoverable amount of the asset is estimated. If the recoverable amount is lower than carrying amount, an impairment loss is recognized.
