Property, plant and equipment are stated at cost less accumulated depreciation and impairment losses.
Depreciation is calculated using the straight-line method to write-off the cost of the assets to their residual values
over their estimated useful lives. The useful lives for this purpose are:
Aircraft
– engine 7 – 25 years
– airframe 7 – 25 years
– service potential 7 – 13 years
Aircraft spares 10 years
Aircraft fixtures and fittings Useful life or, remaining lease
term of aircrafts, whichever is shorter
Buildings 25 – 50 years
Motor vehicles 5 years
Office equipment, furniture and fittings 5 years
Office renovation 5 years
Simulator equipment 25 years
Operating plant and ground equipment 5 years
Kitchen equipment 5 years
Residual values, where applicable, are reviewed annually against prevailing market rates at the balance sheet date
for equivalent aged assets and depreciation rates are adjusted accordingly on a prospective basis. The estimated
residual value for aircraft airframes and engines is 10% of their cost.
Assets not yet in operation are stated at cost and are not depreciated until the assets are ready for their intended
use.
An element of the cost of an acquired aircraft is attributed on acquisition to its service potential reflecting the
maintenance condition of its engines and airframe. This cost, which can equate to a substantial element of the
total aircraft cost, is amortised over the shorter of the period to the next checks or the remaining life of the
aircraft.
The cost of subsequent major airframe and engine maintenance checks as well as upgrades to leased assets are
capitalised and amortised over the shorter of the period to the next check or the remaining life of the aircraft.
At each balance sheet date, the Group assesses whether there is any indication of impairment. If such an
indication exists, an analysis is performed to assess whether the carrying amount of the asset is fully recoverable.
A write down is made if the carrying amount exceeds the recoverable amount. See accounting policy Note 2(f )
on impairment of assets.
Gains and losses on disposals are determined by comparing proceeds with carrying amount and are included in
profit/(loss) from operations.
Advance payments and option payments made in respect of aircraft purchase commitments and options to
acquire aircraft where the balance is expected to be funded by mortgage financing are recorded at cost. On
acquisition of the related aircraft, these payments are included as part of the cost of aircraft and are depreciated
from that date. Where the balance of payment is expected to be funded by lease financing, the advance
payments are classified as deposits.

2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES SCONT’DT
(e) Investments
Investments in subsidiaries, jointly controlled entities and associates are stated at cost less accumulated
impairment losses. Where an indication of impairment exists, the carrying amount of the investment is assessed
and written down immediately to its recoverable amount (see Note 2(f )).
Investments in other non-current investments are shown at cost and an allowance for diminution in value is
made, where in the opinion of the Directors, there is a decline other than temporary in the value of such
investments. Where there has been a decline other than temporary in the value of an investment, such a decline
is recognised as an expense in the period in which the decline is identified.
On disposal of an investment, the difference between net disposal proceeds and its carrying amount is
charged/credited to the income statement.
(f) Impairment of assets
Assets that have an indefinite useful life are not subject to amortisation and are tested for impairment annually, or
as and when events or circumstances occur indicating that an impairment may exist. Property, plant and
equipment and other non-current assets, including intangible assets with definite useful life, are reviewed for
impairment losses whenever events or changes in circumstances indicate that the carrying amount may not be
recoverable. An impairment loss is recognised for the amount by which the carrying amount of the asset exceeds
its recoverable amount. The recoverable amount is the higher of an asset’s fair value less cost to sell and value-inuse.
For the purpose of assessing impairment, assets are grouped at the lowest level for which there is separately
identifiable cash flows (cash-generating units). Assets other than goodwill that suffered an impairment are
reviewed for possible reversal at each reporting date.
Any impairment loss arising is charged to the income statement unless it reverses a previous revaluation in which
