The rule in plain words

If surplus or Deficit of CET1 capital is negative, CET1 capital ratio cannot be more than 0.045.

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

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 blocking check. A filing that fails it is normally rejected, so fix it before you submit.
