Investments in the capital of financial sector entities where the institution has a significant investment: a lower-limit check on capital adequacy: Memorandum items (C 04.00, row 0440, EBA rule v4803_m)

A warning in the own funds and capital requirements return (COREP own funds), on template C 04.00, capital adequacy - Memorandum items.

The rule in plain words

For investments in the capital of financial sector entities where the institution has a significant investment: holdings of CET1 capital of financial sector entities where the institution has a significant investment, net of short positions cannot be less than holdings on CET1 capital instruments of financial sector entities where the institution has a significant investment temporary waived.

All the values are in the amount column (0010) of C 04.00.

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.

Holdings of CET1 capital of financial sector entities where the institution has a significant investment, net of short positions >= Holdings on CET1 Capital Instruments of financial sector entities where the institution has a significant investment temporary waived

What to do if your filing fails it

  1. 01Open the template below and find the cells the rule reads.
  2. 02Compare the values in your file. If the first is smaller than it may be, one of them is wrong: check both before you change either.
  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 04.00 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.

A worked example

The first of its checks, with simple numbers.

Illustrative values
Holdings of CET1 capital of financial sector entities where the institution has a significant investment, net of short positions1,200
What the rule then expects

Holdings on CET1 capital instruments of financial sector entities where the institution has a significant investment temporary waived can then be at most 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.
