1 min readWarningEBA reporting framework 4.2Updated 10 November 2026

Net contractual gap must equal total inflows minus total outflows (C 66.01.w, EBA rule v8773_m)

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

Net contractual gap must equal total inflows minus total outflows.

EBA checks it for 21 columns, from overnight (0020) to greater than 5 years (0220). That makes 21 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.

Greater than 30 days up to 5 weeks: Net contractual gap = Total inflows - Total outflows

What to do if your filing fails it

  1. 01Open the template below and find the cells the rule reads.
  2. 02Work out both sides from your file, as the rule in plain words sets out, and compare them.
  3. 03EBA allows a small rounding difference, worked out from the decimals each value is reported with.
  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.

Illustrative values
Total inflows1,200
Total outflows (taken away)800
Together400
What the rule then expects

Net contractual gap must then be 400.

400Passes
500Fails

A file that reports 400 passes. One that reports 500 fails, by 100.

The numbers are illustrative, reported to the unit, so the rounding tolerance does not change the result.

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}.

{C_66.01.w,r0710,c0120,} = {C_66.01.w,r0700,c0120,} - {C_66.01.w,r0380,c0120,}

The next five:

{C_66.01.w,r0710,c0050,} = {C_66.01.w,r0700,c0050,} - {C_66.01.w,r0380,c0050,}{C_66.01.w,r0710,c0190,} = {C_66.01.w,r0700,c0190,} - {C_66.01.w,r0380,c0190,}{C_66.01.w,r0710,c0220,} = {C_66.01.w,r0700,c0220,} - {C_66.01.w,r0380,c0220,}{C_66.01.w,r0710,c0110,} = {C_66.01.w,r0700,c0110,} - {C_66.01.w,r0380,c0110,}{C_66.01.w,r0710,c0180,} = {C_66.01.w,r0700,c0180,} - {C_66.01.w,r0380,c0180,}

And 15 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.
