Check your file against this ruleWhat to do if it fails

The rule in plain words

If CET1 capital ratio is at most 0.045, surplus or Deficit of CET1 capital must be negative.

All the values are in the amount column (0010) of C 03.00.

How the Line4 Check report words itShow

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

If CET1 Capital ratio <= 0.045, then Surplus(+)/Deficit(-) of CET1 capital < 0

What to do if your filing fails it

  1. 01Open the template below and find the cells the rule reads.
  2. 02The check applies only when its first part holds in your file. When it does, the second part must hold too: fix the second part, or correct the first.
  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 03.00 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.
