Property, Plant and Equipment

Property, plant and equipment, except for the items acquired prior to January 1, 2003, are stated at historical cost, excluding the costs of day-to-day servicing, less accumulated depreciation and any impairment in value.

The items of property, plant and equipment acquired prior to January 1, 2003, the date of transition to IFRS, were accounted for at deemed cost being their fair value as at January 1, 2003.

Depreciation is calculated on a straight-line basis. Average depreciation periods, which represent estimated useful economic lives of respective assets, are as follows:

Land	Not depreciated
Buildings	8-100 years
Machinery andequipment	5-30 years
Other	2-15 years

Expenditure incurred to replace a component of an item of property, plant and equipment that is accounted for separately, including major inspection and overhaul expenditure, is capitalised. Subsequent expenditure is capitalised only when it increases the future economic benefits embodied in the item of property, plant and equipment and can be measured reliably. All other expenditures are recognised in the profit or loss as an expense when incurred.
