None of the twelve values it checks in credit derivatives exposures (CCR 9) can be negative (C 34.09, EBA rule v10325_s)

A warning in the own funds and capital requirements return (COREP own funds), on template C 34.09, credit derivatives exposures (CCR 9).

Check your file against this ruleWhat to do if it fails

The rule in plain words

None of the values it checks in credit derivatives exposures (CCR 9) can be negative.

EBA checks it for two columns: protection bought and protection sold. And for six rows: single-name credit default swaps, index credit default swaps, total return swaps, credit options, other credit derivatives and total. That makes twelve 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.

Protection bought: Total >= 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 34.09 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

Total, protection bought 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.

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

And 6 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.
