IFRS 9 - Impairment (EN)


The "incurred loss model" in accordance with IAS 39 (portfolio and specific loan loss provisions) is replaced by the three-stage "expected credit loss model" of IFRS 9 for calculating risk provisions. In addition to complex design decisions and extensive process and IT adjustments, this requires greater cooperation between accounting and risk management. In addition to the complex three-step standard approach of IFRS 9, far-reaching special regulations are required for financial instruments already impaired at the time of acquisition ("purchased or originated credit-impaired assets"; POCI assets) as well as dependencies on further regulations of IFRS 9, e.g. modifications. The notes disclosures on risk provisioning will be expanded extensively.
