1 min readWarningEBA reporting framework 4.2Updated 10 November 2026

None of the 21 values it checks in detail of the exposures to individual clients within groups of connected clients can be negative (C 29.00, EBA rule v3800_s)

A warning in the large exposures return (COREP LE), on template C 29.00, detail of the exposures to individual clients within groups of connected clients.

The rule in plain words

None of the values it checks in detail of the exposures to individual clients within groups of connected clients can be negative.

EBA checks it for 21 columns, from total original exposure (050) to % of Tier 1 capital (360). That makes 21 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.

Additional exposures arising from transactions where there is an exposure to underlying assets: Additional exposures arising from transactions where there is an exposure to underlying assets >= 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 29.00 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.

A worked example

The first of its checks, with simple numbers.

What the rule then expects

Additional exposures arising from transactions where there is an exposure to underlying assets 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.

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