  Depreciation is calculated on a straight-line basis to write off the cost of each component of an asset to its residual value over its estimated useful life as follows:

Buildings 20 years
Equipment and furniture 3 to 10 years
Motor vehicles 3 to 5 years
Aircraft 20 years

A schedule of land and buildings is available for inspection by members or their authorised agents at the registered office of the company.

Certain property, plant and equipment have been encumbered as security for interest-bearing borrowings amounting to R32 million (2012: R72 million), (refer to note 23).

The total value of property, plant and equipment held under capitalised finance leases included above is R35 million (2012: R84 million).
