(8)In accordance with Article 321(a) of Regulation (EU) No 575/2013, an institution's internal operational risk measurement system has to be closely integrated into its day-to-day risk management processes. As a result, the methodology for AMA assessment should provide for competent authorities to ensure that an institution applying for an AMA permission actually uses its operational risk measurement system for its day-to-day business process and for risk management purposes on an on-going basis and not solely for the purpose of calculating the own funds requirements for operational risk. Rules on the AMA supervisory assessment should therefore include rules on the supervisory expectations to be met by the institution applying for an AMA permission as regards the ‘use test’.
