None of the 18 values it checks in operational risk can be negative (C 17.01.b, EBA rule v5834_s)

A warning in the own funds and capital requirements return (COREP own funds), on template C 17.01.b, operational risk: thresholds applied in data collections.

Check your file against this ruleWhat to do if it fails

The rule in plain words

None of the values it checks in operational risk can be negative.

EBA checks it for two columns: lowest and highest. And for nine rows, from gross loss amount (new events) (0020) to gross loss amount (new events) (0820). 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.

HIGHEST: Gross loss amount (new events) >= 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 17.01 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

Gross loss amount (new events), highest 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}.

{C_17.01.b,r0020,c0100,} >= 0

The next five:

{C_17.01.b,r0120,c0100,} >= 0{C_17.01.b,r0320,c0090,} >= 0{C_17.01.b,r0620,c0090,} >= 0{C_17.01.b,r0720,c0100,} >= 0{C_17.01.b,r0020,c0090,} >= 0

And 12 more, the same formula for the other cells it covers.

Every COREP own funds rule, by template

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