None of the five values it checks in credit risk and free deliveries can be negative (C 08.05.1.a, EBA rule v10483_s)

A warning in the own funds and capital requirements return (COREP own funds), on template C 08.05.1.a, credit risk and free deliveries: IRB approach to capital requirements: back-testing of PD in accordance with Article 180(1), point (f) of Regulation (EU) No 575/2013 (CR IRB 5B) (I).

Check your file against this ruleWhat to do if it fails

The rule in plain words

None of the values it checks in credit risk and free deliveries can be negative.

EBA checks it for five columns: arithmetic average PD (%), number of obligors at the end of the previous year, defaulted during the year, observed average default rate (%) and average historical annual default rate (%). 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.

Of which: defaulted during the year: Of which: defaulted during the year >= 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 08.05.1 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

Credit risk and free deliveries: IRB approach to capital requirements: back-testing of PD in accordance with Article 180(1), point (f) of Regulation (EU) No 575/2013 (CR IRB 5B) (I) (C 08.05.1.a)

  • 0040Observed average default rate (%)
  • 0050Average historical annual default rate (%)

A worked example

The first of its checks, with simple numbers.

What the rule then expects

Defaulted during the year 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.

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