1 min readWarningEBA reporting framework 4.2Updated 10 November 2026

Risk to firm must equal the sum of its four parts (EBA rule v11139_m)

A warning in the investment firms, class 2 return (IFR class 2), on template I 04.00, k-factor requirement calculations.

The rule in plain words

Risk to firm must equal these four added up:

  • Trading counterparty default
  • Daily trading flow - cash trades
  • Daily trading flow - derivative trades
  • K-concentration risk requirement

All the values are in the K-factor requirement column (0020) of I 04.00.

How the Line4 Check report words itShow

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

K-factor requirement: Risk to firm = Trading counterparty default + Daily trading flow - Cash trades + Daily trading flow - Derivative trades + K-Concentration risk requirement

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  3. 03If they differ, a part is missing, a value sits in the wrong row, or the total is out of date.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 I 04.00 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.

What the rule then expects

Risk to firm 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.
