1 min readWarningEBA reporting framework 4.2Updated 10 November 2026

A balancing check on capital adequacy: Memorandum items (C 04.00, row 0100, EBA rule v0225_m)

A warning in the own funds and capital requirements return (COREP own funds), on template C 04.00, capital adequacy - Memorandum items.

The rule in plain words

IRB excess (+) or shortfall (-) of credit risk adjustments, additional value adjustments and other own funds reductions to expected losses f must equal total credit risk adjustments, additional value adjustments and other own funds reductions eligible for inclusion in the calculation of the minus total expected loss eligible.

All the values are in the amount column (0010) of C 04.00.

The headline gives only the kind of check and the template, because the rule is too long to say in a headline. The plain words above say all of it.

How the Line4 Check report words itShow

Word for word as the report shows it when the rule fails.

IRB excess (+) or shortfall (-) of credit risk adjustments, additional value adjustments and other own funds reductions to expected losses f = Total credit risk adjustments, additional value adjustments and other own funds reductions eligible for inclusion in the calculation of the - Total expected loss eligible

What to do if your filing fails it

  1. 01Open the template below and find the cells the rule reads.
  2. 02Work out both sides from your file, as the rule in plain words sets out, and compare them.
  3. 03EBA allows a small rounding difference, worked out from the decimals each value is reported with.
  4. 04It runs only when your filing indicators mark C 04.00 as reported.
  5. 05This is a warning. It does not stop the filing on its own, but your authority may ask you to explain it.

What the rule then expects

IRB excess (+) or shortfall (-) of credit risk adjustments, additional value adjustments and other own funds reductions to expected losses f must then be 400.

400Passes
500Fails

A file that reports 400 passes. One that reports 500 fails, by 100.

The numbers are illustrative, reported to the unit, so the rounding tolerance does not change the result.
