Number cannot be negative (Q 01.00, EBA rule v23217_s)

A warning in the asset-referenced and e-money tokens return (MiCA), on template Q 01.00, s_01.00: number of holders - at reference date.

The rule in plain words

Number cannot be negative.

EBA checks it for five rows: total number of holders, holders of custodial wallet, retail holders (0030), holders of non-custodial wallet and retail holders (0050). That makes five checks. A failure names the one that failed.

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 Q 01.00 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 file that reports 0 passes. One that reports -100 fails, by 100.

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

Every MiCA rule, by template

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