|SELECTED ACCOUNTING PRINCIPLES
Other non-financial assets of the Group include prepayments as well as advance payments for fixed assets under construction, intangible assets, inventories which as non-monetary items are not discounted and costs of acquiring new contracts and costs of rebates. Contract acquisition costs are capitalised if the Group expects to recover them. On the other hand, costs of contract acquisition can be immediately charged to expenses if the period of depreciation of the related asset is up to one year. The asset is depreciated over the period when the goods are transferred or services provided. If the costs are related to more than one contract, depreciation should include both current and projected contracts.
