Percentage cannot be negative (EBA rule v4746_s)

A blocking check in the own funds and capital requirements return (COREP own funds), on template C 09.04, breakdown of credit exposures relevant for the calculation of the countercyclical buffer by country and institution-specific countercyclical buffer rate.

The rule in plain words

Percentage cannot be negative.

EBA checks it for four rows: own funds requirements weights, countercyclical capital buffer rate set by the designated authority, countercyclical capital buffer rate applicable for the country of the institution and institution-specific countercyclical capital buffer rate. That makes four 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.

Percentage: Own funds requirements weights >= 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 09.04 as reported.
  5. 05This is a blocking check. A filing that fails it is normally rejected, so fix it before you submit.

The cells it reads

Breakdown of credit exposures relevant for the calculation of the countercyclical buffer by country and institution-specific countercyclical buffer rate (C 09.04)

Rows

  • 0130Countercyclical capital buffer rate applicable for the country of the institution
  • 0140Institution-specific countercyclical capital buffer rate

A worked example

The first of its checks, with simple numbers.

What the rule then expects

Own funds requirements weights, percentage 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_09.04,r0110,c0020,} >= 0

The next three:

{C_09.04,r0120,c0020,} >= 0{C_09.04,r0130,c0020,} >= 0{C_09.04,r0140,c0020,} >= 0

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.
