| (m) | Investment properties |
Investment properties are measured at cost, net of accumulated depreciation and impairment loss, if any.
Depreciation of the investment properties is determined using the straight-line method with useful life of 20 years.
Investment properties are derecognized either when they have been disposed of or when they are permanently withdrawn from use and no future economic benefit is expected from their disposal. The difference between the net disposal proceeds and the carrying amount of the asset is recognized in profit or loss in the period of derecognition.
Transfers are made to (or from) investment property only when there is a change in use.
For a transfer from investment property to an item of property, plant and equipment, the deemed cost for subsequent accounting is the fair value at the date of change in use. If an item of property, plant and equipment becomes an investment property, the Group accounts for such property in accordance with the policy stated under property, plant and equipment up to the date of change in use.
