Inventories
Inventories comprise the spare parts and materials needed for aircraft repair and maintenance and stocks for customer services. Inventories were evaluated at the average acquisition cost. The value of work in progress includes average salary costs, excluding salary-related costs, used stocks of materials and supplies and subcontracting work
Current Assets
Securities entered under current assets are evaluated at the lower of original acquisition cost or market value.
Leasing
Lease payments for Group aircraft are significant. Annual lease payments are treated as rental expenses. Lease payments due in future years under aircraft lease contracts are presented as off-balance sheet items.
Extraordinary Items
Items included in extraordinary items are typically substantial and one-off by nature. They also deviate from the ordinary course of business operations. Changes in accounting principles and procedures are implemented by using extraordinary items to show the impact on earnings.
