1 min readWarningEBA reporting framework 4.2Updated 10 November 2026

Combined buffer requirement must equal the sum of its four parts (M 03.00, EBA rule v10784_m)

A warning in the loss-absorbing capacity return (MREL and TLAC), on template M 03.00, internal MREL and internal TLAC (ILAC).

The rule in plain words

Combined buffer requirement (%) must equal these four added up:

  • Capital conservation buffer requirement
  • Countercyclical buffer requirement
  • Systemic risk buffer requirement
  • Global Systemically Important institution (G-SII) or other Systemically Important institution (O-SII) buffer

All the values are in the internal TLAC column (0020) of M 03.00.

How the Line4 Check report words itShow

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

Internal TLAC: Combined buffer requirement (%) = Of which: capital conservation buffer requirement + Of which: countercyclical buffer requirement + Of which: systemic risk buffer requirement + Of which: Global Systemically Important Institution (G-SII) or Other Systemically Important Institution (O-SII) buffer

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  3. 03If they differ, a part is missing, a value sits in the wrong row, or the total is out of date.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 M 03.00 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.

A worked example

The first of its checks, with simple numbers.

Illustrative values
capital conservation buffer requirement1,200
countercyclical buffer requirement800
systemic risk buffer requirement450
Global Systemically Important institution (G-SII) or other Systemically Important institution (O-SII) buffer300
Together2,750
What the rule then expects

Combined buffer requirement (%) 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.

EBA's formula. Cells are written as {template, row, column, sheet}.

{M_03.00,r0500,c0020,} = {M_03.00,r0510,c0020,} + {M_03.00,r0520,c0020,} + {M_03.00,r0530,c0020,} + {M_03.00,r0540,c0020,}

Every MREL and TLAC rule, by template

Checks like this one, run at the point of submission, are the first step to real-time supervision.
