Aptivaa is launching a blog series to explain key aspects of IFRS 9, focusing on impairment modeling and the challenges banks face in its implementation. IFRS 9 introduces a forward-looking expected loss approach, replacing the incurred loss model from IAS 39, and emphasizes the need for collaboration between risk and finance teams to avoid issues during implementation. The standard will take effect for annual periods beginning on or after January 1, 2018, necessitating a minimum of two years for banks to adapt their systems and processes.
