1 min readWarningEBA reporting framework 4.2Updated 10 November 2026

Number of clients cannot be negative (EBA rule v90255_s)

A warning in the resolution planning: critical functions and services return (RESOL2), on template Z 07.01.3.a, criticality assessment of economic functions (FUNC 1 PAY).a.

The rule in plain words

Number of clients cannot be negative.

EBA checks it for eleven rows, from payment services to MFIs (0160) to other services / activities / functions (3) (0240). That makes eleven 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.

Number of Clients: Securities settlement services >= 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 Z 07.01.3 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.

What the rule then expects

Securities settlement services, number of clients must then be at least 0.

0Passes
-100Fails

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

The numbers are illustrative.

Show the rule as writtenShow

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

{Z_07.01.3.a,r0190,c0110,} >= 0

The next five:

{Z_07.01.3.a,r0240,c0110,} >= 0{Z_07.01.3.a,r0176,c0110,} >= 0{Z_07.01.3.a,r0174,c0110,} >= 0{Z_07.01.3.a,r0200,c0110,} >= 0{Z_07.01.3.a,r0160,c0110,} >= 0

And 5 more, the same formula for the other cells it covers.

Every RESOL2 rule, by template

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