(2)The choice of the subset of the modellable risk factors referred to in Article 325bc(2) of Regulation (EU) No 575/2013 is a part of the institution’s approved and documented set of internal policies and procedures. Where the institution modifies its policies and procedures related to the choice of modellable risk factors, that modification should be approved by or notified to the competent authority, as it constitutes a change to the choice of the subset of the modellable risk factors. By contrast, changes to the composition of the list of risk factors included in the subset of modellable risk factors referred to in Article 325bc(2) of that Regulation, which take place within the approved policies and procedures, including in the case of a reduction in data availability, should not be considered as changes to the institution’s choice of the subset of modellable risk factors.
