(h)
Property, plant and equipment (cont’d)
(i
) Other property, plant and equipment (cont’d)
The cost of self-constructed items of property, plant and equipment includes the cost of materials, the initial estimate, where relevant, of the costs of dismantling and removing the items and restoring the site on which they are located, and an appropriate proportion of production overheads and borrowing costs (Note 2(y)).
Gains or losses arising from the retirement or disposal of an item of property, plant and equipment are determined as the difference between the net disposal proceeds and the carrying amount of the item and are recognised in profit or loss on the date of retirement or disposal. Any related revaluation surplus is transferred from the revaluation reserve to retained profits.
Depreciation is calculated to write off the cost or valuation of items of property, plant and equipment, less their estimated residual value, if any, using the straight line method over their estimated useful lives as follows:
Buildings 30 to 35 years
Owned and leased aircraft 15 to 20 years
Other flight equipment
– Jet engines 15 to 20 years
– Others, including rotable spares 2.5 to 15 years
Machinery and equipment 4 to 10 years
Vehicles 6 to 8 years
Where parts of an item of property, plant and equipment have different useful lives, the cost or valuation of the item is allocated on a reasonable basis between the parts and each part is depreciated separately. Both the useful life of an asset and its residual value, if any, are reviewed annually.
(i) Construction in progress
Construction in progress represents office buildings, various infrastructure projects under construction and equipment pending installation, and is stated at cost less impairment losses (Note 2(l)). Capitalisation of these costs ceases and the construction in progress is transferred to property, plant and equipment when the asset is substantially ready for its intended use, notwithstanding any delay in the issue of the relevant commissioning certificates by the relevant PRC authorities.
No depreciation is provided in respect of construction in progress.
(j) Leased assets An arrangement, comprising a transaction or a series of transactions, is or contains a lease if the Group determines that the arrangement conveys a right to use a specific asset or assets for an agreed period of time in return for a payment or a series of payments. Such a determination is made based on an evaluation of the substance of the arrangement and is regardless of whether the arrangement takes the legal form of a lease.

60 ANNUAL REPORT 2008
Assets that are held by the Group under leases which transfer to the Group substantially all the risks and rewards of ownership are classified as being held under finance leases. Leases which do not transfer substantially all the risks and rewards of ownership to the Group are classified as operating leases, except for land held for own use under an operating lease, the fair value of which cannot be measured separately from the fair value of a building situated thereon at the inception of the lease, is accounted for as being under a finance lease, unless the building is also clearly held under an operating lease. For these purposes, the inception of the lease is the time that the lease was first entered into by the Group, or taken over from the previous lessee.
