1 min readWarningEBA reporting framework 4.2Updated 10 November 2026

Exposure value cannot be negative (C 34.10, EBA rule v10302_s)

A warning in the own funds and capital requirements return (COREP own funds), on template C 34.10, exposures to CCPs (CCR 10).

Check your file against this ruleWhat to do if it fails

The rule in plain words

Exposure value cannot be negative.

EBA checks it for 18 rows, from exposures for trades at QCCPs (excluding initial margin and default fund contributions); of which (0020) to unfunded default fund contributions (0200). That makes 18 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.

Exposure value: (i) OTC derivatives >= 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 34.10 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

OTC derivatives, exposure value 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.
