Percentage of total assets times total assets must equal size of the derivative business (EBA rule v10638_m)

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

Percentage of total assets times total assets must equal size of the derivative business.

EBA checks it for three columns: total (0030), total (0060) and total (0090). That makes three 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: Percentage of total assets × Total assets = Size of the derivative business

What to do if your filing fails it

  1. 01Open the template below and find the cells the rule reads.
  2. 02Work out both sides from your file, as the rule in plain words sets out, and compare them.
  3. 03EBA allows a small rounding difference, worked out from the decimals each value is reported with.
  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

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

{C_34.01.a,r0050,c0060,} * {C_34.01.a,r0040,c0060,} = {C_34.01.a,r0010,c0060,}

The next two:

{C_34.01.a,r0050,c0030,} * {C_34.01.a,r0040,c0030,} = {C_34.01.a,r0010,c0030,}{C_34.01.a,r0050,c0090,} * {C_34.01.a,r0040,c0090,} = {C_34.01.a,r0010,c0090,}

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