Check your file against this ruleWhat to do if it fails

The rule in plain words

Total exposures cannot be more than exposures secured by mortgages on residential immovable property – IPRE.

EBA checks it for five columns: (-) guarantees, (-) credit derivatives, (-) other funded credit protection, (-) total outflows, and (-) value adjustments and provisions. That makes five 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.

(-) Guarantees: Total exposures <= of which: Secured by mortgages on residential immovable property – IPRE

What to do if your filing fails it

  1. 01Open the template below and find the cells the rule reads.
  2. 02Compare the values in your file. If the first is bigger than it may be, one of them is wrong: check both before you change either.
  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 08.01 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.

Illustrative values
Total exposures1,200
What the rule then expects

Exposures secured by mortgages on residential immovable property – IPRE must then be at least 1,200.

1,200Passes
1,100Fails

A file that reports 1,200 passes. One that reports 1,100 fails, by 100.

The numbers are illustrative, reported to the unit, so the rounding tolerance does not change the result.

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