1 min readWarningEBA reporting framework 4.2Updated 10 November 2026

Total must equal the sum of its five parts (C 34.09, EBA rule v09846_m)

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

Total must equal these five added up:

  • Single-name credit default swaps
  • Index credit default swaps
  • Total return swaps
  • Credit options
  • Other credit derivatives

EBA checks it for two columns: protection bought and protection sold. That makes two 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 sold: Total = Single-name credit default swaps + Index credit default swaps + Total return swaps + Credit options + Other credit derivatives

What to do if your filing fails it

  1. 01Open the template below and find the cells the rule reads.
  2. 02Add up the parts in your file and compare the result with the total.
  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
  4. 04EBA allows a small rounding difference, worked out from the decimals each value is reported with.
  5. 05It runs only when your filing indicators mark C 34.09 as reported.
  6. 06This is a warning. It does not stop the filing on its own, but your authority may ask you to explain it.

A worked example

Single-name credit default swaps1,200
Index credit default swaps800
Total return swaps450
Credit options300

Together2,900
What the rule then expects

Total must then be 2,900.

2,900Passes
3,000Fails

A file that reports 2,900 passes. One that reports 3,000 fails, by 100.

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

Show the rule as writtenShow

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

{C_34.09,r0060,c0020,} = {C_34.09,r0010,c0020,} + {C_34.09,r0020,c0020,} + {C_34.09,r0030,c0020,} + {C_34.09,r0040,c0020,} + {C_34.09,r0050,c0020,}

The next one:

{C_34.09,r0060,c0010,} = {C_34.09,r0010,c0010,} + {C_34.09,r0020,c0010,} + {C_34.09,r0030,c0010,} + {C_34.09,r0040,c0010,} + {C_34.09,r0050,c0010,}

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