Exposure cannot be negative (L 08.02, EBA rule v22722_s)

A warning in the financial conglomerates return (FC), on template L 08.02, risk concentration – exposure by asset class and rating.

Check your file against this ruleWhat to do if it fails

The rule in plain words

Exposure cannot be negative.

EBA checks it for six rows: aaa, aa, A, bbb, non investment grade and total. And on three sheets: national government, international financial organisation and central banks bonds, regional governments, local authorities and public sector entities bonds, and corporate bonds. 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.

Exposure: AA, Regional governments, local authorities and public sector entities bonds >= 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 L 08.02 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 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}.

{L_08.02,r0020,c0010,s0002} >= 0

The next five:

{L_08.02,r0040,c0010,s0003} >= 0{L_08.02,r0010,c0010,s0003} >= 0{L_08.02,r0020,c0010,s0001} >= 0{L_08.02,r0050,c0010,s0003} >= 0{L_08.02,r0060,c0010,s0003} >= 0

And 12 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.
