Future realisations can be influenced by many factors, including: • national and international market activities; • fluctuations in interest rates and foreign exchange rates; • economic and political conditions in certain business sectors or countries; • changes in regulations or legislation. This list is not exhaustive. Accounting estimates which require assumptions to be made are mainly used for the following measurements: • financial instruments measured at fair value (including non-consolidated holdings) • liabilities arising from investment contracts without discretionary participation features • pension plans and other future benefits • stock option plans • impairment of debt instruments at amortised cost at fair value through other comprehensive income recyclable to income • provisions • impairment losses on goodwill • deferred tax assets • valuation of companies accounted for by the equity method. The procedures for the use of judgement or estimates are described in the relevant sections below. Annual Report 2025 79
