Common equity tier 1 capital: a matching-values check across capital adequacy: own funds definition and capital adequacy: transitional provisions: Summary (C 01.00, C 05.01, EBA rule v0191_m)

A warning in the own funds and capital requirements return (COREP own funds), on templates C 01.00, capital adequacy - own funds definition and C 05.01, capital adequacy - transitional provisions: Summary.

The rule in plain words

For common equity tier 1 capital: (-) deferred tax assets that rely on future profitability and do not arise from temporary differences net of associated tax liabilities, amount must equal deferred tax assets that rely on future profitability and do not arise from temporary differences, eligible amount without transitional provisions.

The headline gives only the kind of check and the template, because the rule is too long to say in a headline. The plain words above say all of it.

How the Line4 Check report words itShow

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

C_01.00: (-) Deferred tax assets that rely on future profitability and do not arise from temporary differences net of associated tax liabilities = C_05.01: Deferred tax assets that rely on future profitability and do not arise from temporary differences, Eligible amount without transitional provisions

What to do if your filing fails it

  1. 01Open the templates below and find the cells the rule reads.
  2. 02The two values must be the same. Find which of the two is right, and correct the other one.
  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 01.00 and C 05.01 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.

A worked example

The first of its checks, with simple numbers.

Illustrative values
(-) deferred tax assets that rely on future profitability and do not arise from temporary differences net of associated tax liabilities, amount1,200
What the rule then expects

Deferred tax assets that rely on future profitability and do not arise from temporary differences, eligible amount without transitional provisions must then be 1,200.

1,200Passes
1,300Fails

A file that reports 1,200 passes. One that reports 1,300 fails, by 100.

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