1 min readSwitched off by EBA on 17 March 2026EBA reporting framework 4.2Updated 10 November 2026

The sum of three columns must equal 1 (EBA rule v09796_m)

A check in the own funds and capital requirements return (COREP own funds), on template C 08.07, credit risk and free deliveries: IRB approach to capital requirements: scope of use of IRB and SA approaches (CR IRB 7).

EBA switched this rule off for filings submitted from 17 March 2026, in a quarterly update to its list of validation rules. It no longer applies, so a failure here does not count, and Line4 Check does not run it.

The rule in plain words

These three added up must equal 1:

  • Percentage of total exposure value subject to permanent partial use of SA (%)
  • Percentage of total exposure value subject to a roll-out plan (%)
  • Percentage of total exposure value subject to IRB approach (%)

All the values are in the corporates row (0050) of C 08.07.

EBA writes it out 22 times. These words are for the first; the others are the same rule on other cells.

EBA's formula, as written out for the first of its checks. Cells are written as {template, row, column, sheet}.

{C_08.07,r0050,c0030,} + {C_08.07,r0050,c0040,} + {C_08.07,r0050,c0050,} = 1

And 21 more, the same formula for the other cells it covers.

Checks like this one, run at the point of submission, are the first step to real-time supervision.
