Article 3
Principles of classification of extensions and changes
The classification of extensions and changes in the AMA shall be carried out in accordance with this Article and Articles 6 and 7.
The classification of extensions and changes in the IMA shall be carried out in accordance with this Article and Articles 7a and 7b.
Where institutions are required to calculate the quantitative impact of any extension or change on own funds requirements or, where applicable, on risk-weighted exposure amounts, they shall apply the following methodology:
for the purpose of the assessment of the quantitative impact institutions shall use the most recent data available;
where a precise assessment of the quantitative impact is not feasible, institutions shall instead perform an assessment of the impact based on a representative sample or other reliable inference methodologies;
for changes having no direct quantitative impact, no quantitative impact as laid down in Article 4(1)(c) for IRB approach or Article 6(1)(c) for AMA or Article 7a(1)(c) for IMA needs to be calculated.
