32 Asset life
32.1 EUROCONTROL recommended values
Table 32.1 presents the accounting period, in years, for a given asset used to derive the depreciation of investment expenditure.
Asset life as used in cost-benefit analyses reflects the expected operating life of the specific equipment concerned, which is also the basis for calculating depreciation costs which are taken into account to determine route charges.
The above data provide indicative parameters for classes of equipment for economic analyses. The actual percentages to be applied in calculating the depreciation of fixed assets must be determined in accordance with the expected operating life and the pertinent International Financial Reporting Standards issued by the International Accounting Standards Board.
