(8)This Regulation is largely based on the internationally agreed standards on assigning risk weights to specialised lending exposures. Given the variety of specialised lending exposures and given the specificities of such exposures, it may not capture all risk drivers which institutions identify in their daily business, either for particular types of exposures within the meaning of point 2 of Article 142(1) of Regulation (EU) No 575/2013 or for individual specialised lending exposures. Given that the institutions are required by Article 171(2) of Regulation (EU) No 575/2013 to take into account all relevant information for assignment of obligors and facilities to grades or pools, the institutions should be required to take into account each of any additional risk drivers and consider it jointly with the sub-factor of the specialised lending exposure framework which most closely corresponds to the risk driver. Where this is done for an individual specialised lending exposure, it should be considered an override for the purposes of Article 172(3) of Regulation (EU) No 575/2013. The institution should document why it was appropriate to take into account additional risk drivers and provide a justification for it.
