None of the twelve values it checks in size of the derivative business (CCR 1) (I) can be negative (C 34.01.a, row 0010, EBA rule v10308_s)

A warning in the own funds and capital requirements return (COREP own funds), on template C 34.01.a, size of the derivative business (CCR 1) (I).

The rule in plain words

None of the values it checks in size of the derivative business (CCR 1) (I) can be negative.

EBA checks it for three columns: total (0030), total (0060) and total (0090). And for four rows: size of the derivative business, on- and off-balance sheet derivatives, total assets, and percentage of total assets. 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.

Total: Size of the derivative business >= 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 34.01 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.

The cells it reads

Size of the derivative business (CCR 1) (I) (C 34.01.a)

Rows

  • 0010Size of the derivative business
  • 0020On- and off-balance sheet derivatives
  • 0040Total assets
  • 0050Percentage of total assets

Columns

  • 0060Total
  • 0090Total

A worked example

The first of its checks, with simple numbers.

What the rule then expects

Size of the derivative business, total 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.

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.
