Bank of Russia allowed VTB to switch to an advanced approach to credit risk assessment, the IRB approach or TAC approach. Using the bank's own methods and models will allow it to assess credit risks more accurately and save capital, showing higher capital adequacy. Transition to IRB will last for about three years. VTB became the fourth systemically important bank to receive permission from the regulator to use its own methodologies. Previously, only Sberbank, Raiffeisenbank and Alfa Bank had this right.
