Debtors and creditors with no stated interest rate, which are due within one year, are stated at the transaction price. Any losses arising from impairment are recognised in the statement of comprehensive income within administrative expenses.

At each balance sheet date, assets not measured at fair value are reviewed for any indication that the asset may be impaired at the balance sheet date. If such indication exists, the recoverable amount of the asset, or the asset's cash generating unit, is estimated and compared to the carrying amount. Where the carrying amount exceeds its recoverable amount, an impairment loss is recognised in the profit and loss account unless the asset is carried at a revalued amount, where the impairment loss is recognised as a revaluation reduction.
