ANNUAL REPORT ‘12
NOTES TO THE FINANCIAL STATEMENTS

These properties are recorded as the value of the initial exchange liquidated by the companies and are subject to
legal re-evaluations, within the scope of the former standards, which constitutes the presumed cost at the date of
transition. The fixed tangible assets are being amortised by the respective estimated useful life.
The subsequent costs have been included in the sum recorded on the amount of the property or shown as separate
assets, when appropriate, only when it is likely that it will result in economic benefits for the companies and the
cost can be reliably measured. Other expenditure related to repairs and maintenance has been shown as an expense
during the period in which it was incurred.
The costs incurred with loans obtained for the construction of qualifiable assets have been capitalised during the
time period necessary to complete and prepare the asset for its intended use. Other costs with loans have been
shown as expenditure for the period.
Direct costs related to the technical areas involved in constructing the Group’s assets are likewise capitalised into
tangible assets. This capitalisation is carried out according to the internal resources used and the time spent, as a
counterpart to the heading of work executed by the entity and capitalised.
The gains or losses derived from the sale or writing off of assets are determined by the difference between the
receipts from the sale and the sum recorded on the amount of the asset and is shown as income or expenses on
the income statement.
The average period of useful life of the main fixed tangible assets can be summarised as follows:
2.6.2_Intangible assets – Concession right
In accordance with the Concession Contracts of the companies ANA, S.A. and ANAM, S.A. and the economic regu-
lation established in those instruments, as described in notes 1.3 and 1.4.1, the model for recording the concession
assets as applied under IFRIC 12 is that of intangible asset. There was no obligation for payment by the grantor for
the management of the public service provided (operation and investment), only the fees charged to the airport
users, while ANA, S.A. and ANAM, S.A. bear the risk of demand.
In determining the assets to be classified as belonging to the concession right, the classes of assets associated to
the various activities carried out were identified, being considered as assets integrating the concession right those
that are related to the services/activities in which:
i) The grantor controls or regulates:
Buildings
