Impairment of other financial assets
At each balance sheet date, the Group assesses whether there is objective evidence that a financial asset or a group of financial assets is impaired. In the specific case of equity investments classified as available-for-sale, a significant or prolonged decline in the fair value of the security below its cost is considered in determining whether the assets are impaired. ‘Significant’ and ‘prolonged’ are interpreted on a case-by-case basis for specific equity securities; generally 25% and 6 months are used as triggers. If any objective evidence exists for available-for-sale debt and equity investments, the cumulative loss – measured as the difference between the acquisition cost and the current fair value, less any impairment loss on that financial asset previously recognised in net result – is removed from equity and recognised in the profit and loss account. Impairment losses recognised on equity instruments can never be reversed. If, in a subsequent period, the fair value of a debt instrument classified as available-for-sale increases and the increase can be objectively related to an event occurring after the impairment loss was recognised in the profit and loss account, the impairment loss is reversed through the profit and loss account.
