Check your file against this ruleWhat to do if it fails

The rule in plain words

Deductions must equal these four added up:

  • Deferred tax assets that rely on future profitability and do not arise from temporary differences
  • Deferred tax assets that are dependent on future profitability and arise from temporary differences and CET1 instruments of financial sector
  • Deferred tax assets that are dependent on future profitability and arise from temporary differences
  • Exemption from deduction of equity holdings in insurance companies from CET 1 items

All the values are in the adjustments to CET1 column (0010) of C 05.01.

How the Line4 Check report words itShow

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

Adjustments to CET1: Deductions = Deferred tax assets that rely on future profitability and do not arise from temporary differences + Deferred tax assets that are dependent on future profitability and arise from temporary differences and CET1 instruments of financial sector + Deferred tax assets that are dependent on future profitability and arise from temporary differences + Exemption from deduction of Equity Holdings in Insurance Companies from CET 1 Items

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  3. 03If they differ, a part is missing, a value sits in the wrong row, or the total is out of date.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 05.01 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.

What the rule then expects

Deductions must then be 2,750.

2,750Passes
2,850Fails

A file that reports 2,750 passes. One that reports 2,850 fails, by 100.

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