((a))following the decision on the permanent partial use of the Standardised Approach, the exposure value and the risk-weighted exposure amount of the exposures to which the institution applies the IRB Approach, calculated taking into account the guidance set out in the ECB Guide to internal models, are equal or higher than 50% of the total exposure value and the total risk-weighted exposure amount on a consolidated level of a significant supervised group or on an individual level of a significant supervised entity, if such significant supervised entity is not part of a significant supervised group;

2. 2. The assessment concerning the permanent partial use of the Standardised Approach shall be carried out in accordance with Article 150 of Regulation (EU) No 575/2013 and implementing and regulatory technical standards adopted by the Commission, also taking into consideration any applicable ECB guides or similar documents issued by the ECB, as well as Guidelines and final draft regulatory technical standards of the European Supervisory Authorities.
