1 min readWarningEBA reporting framework 4.2Updated 10 November 2026

Open maturity items cannot be negative (C 66.01.w, EBA rule v11579_s)

A warning in the additional liquidity monitoring metrics return (ALMM), on template C 66.01.w, maturity ladder, significant currencies, overnight and higher maturity.

The rule in plain words

Open maturity items cannot be negative.

EBA checks it for 18 rows, from liabilities not reported in 1.2, resulting from deposits received (excluding deposits received as collateral) (0260) to other counterparties (0650). That makes 18 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.

Of which: Open Maturity items: Central banks >= 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 66.01 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.

A worked example

The first of its checks, with simple numbers.

What the rule then expects

Central banks, open maturity items 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.

And 12 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.
