Validation rules taxonomy V4.0 C_08.01.a,C_09.02 - v0418_m

The validation rule formula v0418_m specifies that the Risk Weighted Assets (RWA) reported under form 09.02 for IRB exposure class central governments and central banks of all country should be less than or equal to RWA reported under form C_08.01.a, column 0255 where Sheets are in qAE:qx2021 (Central governments and central banks with own estimates of LGD and/or conversion factors), qAE:qx2020 (Central governments and central banks without own estimates of LGD or conversion factors), qAE:qx2014 (Corporates - Specialised Lending without own estimates of LGD or conversion factors), qAE:qx2055 (Retail exposures - Purchased receivables - with own estimates of LGD or conversion factors). The Sheet qAE:qx2014 and qAE:qx2055 should not be considered in the formula for comparison of exposure to central government and central bank. These two sheet’s codes are also not part of validation rule v0415_m and v0416_m where the similar comparison is made for original exposure and Exposure at Default (EAD). The control seems incoherent.

While comparing central government exposure in 09.02 the Sheets qx2014 i.e. Corporates - Specialised Lending without own estimates of LGD or conversion factors; qx2055 i.e. Retail exposures - Purchased receivables - with own estimates of LGD or conversion factors of form C_08.01a are incorrectly included.
