Check your file against this ruleWhat to do if it fails

The rule in plain words

(-) own CET1 instruments must equal these three added up:

  • (-) direct holdings of CET1 instruments
  • (-) indirect holdings of CET1 instruments
  • (-) synthetic holdings of CET1 instruments

All the values are in the amount column (0010) of C 01.00.

How the Line4 Check report words itShow

Word for word as the report shows it when the rule fails.

(-) Own CET1 instruments = (-) Direct holdings of CET1 instruments + (-) Indirect holdings of CET1 instruments + (-) Synthetic holdings of CET1 instruments

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  3. 03If they differ, a part is missing, a value sits in the wrong row, or the total is out of date.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 01.00 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.

What the rule then expects

(-) own CET1 instruments must then be 2,450.

2,450Passes
2,550Fails

A file that reports 2,450 passes. One that reports 2,550 fails, by 100.

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