IFRS 9 governs the accounting treatment of financial instruments and replaces the provisions of IAS 39 in the areas of classification, risk provisioning and micro hedge accounting. Under IFRS 9, financial instruments are measured at amortised cost (AC), fair value through other comprehensive income (FVOCI) and fair value through profit or loss (FVPL) depending on extensive criteria. The AC and FVOCI categories are subject to a complex three-level risk provision model based on an expected credit loss approach. IFRS 9 contains numerous exceptions and options and requires extensive adjustments to the process and IT infrastructure. In addition to the ongoing implementation, comprehensive first-time application regulations must be observed.
