Market share must be between 0.000001 and 1 (Z 07.01.2, EBA rule v90331_m)

A warning in the resolution planning: critical functions and services return (RESOL2), on template Z 07.01.2, criticality assessment of economic functions (FUNC 1 LEN).

Check your file against this ruleWhat to do if it fails

The rule in plain words

Market share must be between 0.000001 and 1.

EBA checks it for eight rows: households - lending for house purchase, households - other lending, non-financial corporations - SMEs, non-financial corporations - non-SMEs, general governments, other sectors / counterparties (1), other sectors / counterparties (2) and other sectors / counterparties (3). That makes eight 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.

Market share: 0.000001 <= Other sectors / counterparties (2) and Other sectors / counterparties (2) <= 1

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 outside the range in these cells.
  3. 03If the value is a percentage, EBA expects it as a decimal: 12% is reported as 0.12.
  4. 04EBA compares the values exactly here: there is no rounding tolerance.
  5. 05It runs only when your filing indicators mark Z 07.01.2 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.

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}.

1e-06 <= {Z_07.01.2,r0140,c0020,} and {Z_07.01.2,r0140,c0020,} <= 1

The next five:

1e-06 <= {Z_07.01.2,r0100,c0020,} and {Z_07.01.2,r0100,c0020,} <= 11e-06 <= {Z_07.01.2,r0110,c0020,} and {Z_07.01.2,r0110,c0020,} <= 11e-06 <= {Z_07.01.2,r0150,c0020,} and {Z_07.01.2,r0150,c0020,} <= 11e-06 <= {Z_07.01.2,r0120,c0020,} and {Z_07.01.2,r0120,c0020,} <= 11e-06 <= {Z_07.01.2,r0130,c0020,} and {Z_07.01.2,r0130,c0020,} <= 1

And 2 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.
