2 min readWarningEBA reporting framework 4.2Updated 10 November 2026

None of the 280 values it checks in geographical breakdown of exposures can be negative (C 09.01.a, EBA rule v3724_s)

A warning in the own funds and capital requirements return (COREP own funds), on template C 09.01.a, geographical breakdown of exposures by residence of the obligor (SA exposures).

Check your file against this ruleWhat to do if it fails

The rule in plain words

None of the values it checks in geographical breakdown of exposures can be negative.

EBA checks it for eight columns: original exposure pre conversion factors, general credit risk adjustments, specific credit risk adjustments, write-offs, additional value adjustments and other own funds reductions, exposure value, risk weighted exposure amount pre supporting factors and pre FX-mismatch, and risk weighted exposure amount after supporting factors and after FX-mismatch. And for 35 rows, from central governments or central banks (0010) to acquisition, development and construction (ADC) (0906). That makes 280 checks. A failure names the one that failed.

How the Line4 Check report words itShow

The first of its checks, word for word as the report shows it when it fails. The others read the same, with their own column, row or sheet.

ORIGINAL EXPOSURE PRE CONVERSION FACTORS: Claims in the form of CIU >= 0

What to do if your filing fails it

  1. 01Open the template below and find the cells the rule reads.
  2. 02Look for a value with the wrong sign in these cells, such as an amount entered as a negative number.
  3. 03EBA compares the values exactly here: there is no rounding tolerance.
  4. 04It runs only when your filing indicators mark C 09.01 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.

A worked example

The first of its checks, with simple numbers.

What the rule then expects

Claims in the form of CIU, original exposure pre conversion factors must then be at least 0.

0Passes
-100Fails

A file that reports 0 passes. One that reports -100 fails, by 100.

The numbers are illustrative.
