1 min readWarningEBA reporting framework 4.2Updated 10 November 2026

Negative loss adjustment amounts cannot be more than zero (EBA rule v90221_s)

A warning in the own funds and capital requirements return (COREP own funds), on template C 17.01.a, operational risk: losses and recoveries by business lines and event types in the last year.

The rule in plain words

(-) negative loss adjustment amounts cannot be more than zero.

EBA checks it for seven columns: internal fraud, external fraud, employment practices and workplace safety, clients, products & business practices, damage to physical assets, business disruption and system failures, and execution, delivery & process management. That makes seven checks. A failure names the one that failed.

How the Line4 Check report words itShow

The first of its checks, word for word as the report shows it when it fails. The others read the same, with their own column, row or sheet.

EXTERNAL FRAUD: of which: (-) negative loss adjustment amounts <= 0

What to do if your filing fails it

  1. 01Open the template below and find the cells the rule reads.
  2. 02Look for a value with the wrong sign in these cells, such as an amount entered as a negative number.
  3. 03EBA compares the values exactly here: there is no rounding tolerance.
  4. 04It runs only when your filing indicators mark C 17.01 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.

What the rule then expects

100Fails

A file that reports 0 passes. One that reports 100 fails, by 100.

The numbers are illustrative.

EBA's formula, as written out for the first of its checks. Cells are written as {template, row, column, sheet}.

{C_17.01.a,r0946,c0020,} <= 0

The next five:

{C_17.01.a,r0946,c0070,} <= 0{C_17.01.a,r0946,c0060,} <= 0{C_17.01.a,r0946,c0050,} <= 0{C_17.01.a,r0946,c0030,} <= 0{C_17.01.a,r0946,c0010,} <= 0

And 1 more, the same formula for the other cells it covers.

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