Credit risk mitigation (CRM) techniques with substitution effects on the exposure: not qualifying for differentiated capital treatment must equal the sum of its two parts (EBA rule v23529_h)

A warning in the own funds and capital requirements return (COREP own funds), on template C 13.01, (CR sec) credit risk: securitisations.

Check your file against this ruleWhat to do if it fails

The rule in plain words

For credit risk mitigation (CRM) techniques with substitution effects on the exposure: not qualifying for differentiated capital treatment must equal exposures in NPE securitisations plus exposures in non-NPE securitisations.

EBA checks it for 90 columns, from original exposure pre conversion factors (0050) to specific treatment of senior tranches in qualifying NPE securitisations (0960). That makes 90 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.

(-) UNFUNDED CREDIT PROTECTION: ADJUSTED VALUES (Ga): NOT QUALIFYING FOR DIFFERENTIATED CAPITAL TREATMENT = EXPOSURES IN NPE SECURITISATIONS + EXPOSURES IN NON-NPE SECURITISATIONS

What to do if your filing fails it

  1. 01Open the template below and find the cells the rule reads.
  2. 02Add up the parts in your file and compare the result with the total.
  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
  4. 04EBA allows a small rounding difference, worked out from the decimals each value is reported with.
  5. 05It runs only when your filing indicators mark C 13.01 as reported.
  6. 06This 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
Exposures in NPE securitisations1,200
Exposures in non-NPE securitisations800
Together2,000
What the rule then expects

Not qualifying for differentiated capital treatment must then be 2,000.

2,000Passes
2,100Fails

A file that reports 2,000 passes. One that reports 2,100 fails, by 100.

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

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

{C_13.01,r0360,c0080,} = {C_13.01,r0373,c0080,} + {C_13.01,r0361,c0080,}

The next five:

{C_13.01,r0360,c0110,} = {C_13.01,r0373,c0110,} + {C_13.01,r0361,c0110,}{C_13.01,r0360,c0680,} = {C_13.01,r0373,c0680,} + {C_13.01,r0361,c0680,}{C_13.01,r0360,c0923,} = {C_13.01,r0373,c0923,} + {C_13.01,r0361,c0923,}{C_13.01,r0360,c0420,} = {C_13.01,r0373,c0420,} + {C_13.01,r0361,c0420,}{C_13.01,r0360,c0360,} = {C_13.01,r0373,c0360,} + {C_13.01,r0361,c0360,}
