The rules, on centralbank.ie

How they were counted

Rule codes in sheet 'cbiaor' of 'CBI 2.4 Business rules.xlsx' whose 'Severity and modules' column names aor, with Include in XBRL = yes and Deactivated = no: 40 of the 43 listed (3 have Include in XBRL = no).

Counts are in the CBI's own unit, so they are not comparable with other regulators' counts.
