INVENTORIES

9.1    Accounting policies

Inventory balances mainly comprise materials for maintenance and replacement of flight equipment parts. Inventories are measured at average acquisition cost plus expenses such as non-recoverable taxes, customs expenses incurred in the acquisition, and expenses with transportation to the warehouse. Expenses with freight transfers between operational bases are not capitalized, if incurred. Provisions for obsolescence of inventories are recorded for items not expected to be realized.
