1 min readWarningEBA reporting framework 4.2Updated 10 November 2026

Cumulated net contractual gap must equal net contractual gap (C 66.01.a, EBA rule v10658_m)

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

The rule in plain words

Cumulated net contractual gap must equal net contractual gap.

All the values are in the overnight column (0020) and on the total currencies sheet (0010) of C 66.01.a.

How the Line4 Check report words itShow

Word for word as the report shows it when the rule fails.

Overnight: Cumulated net contractual gap, Total currencies = Net contractual gap, Total currencies

What to do if your filing fails it

  1. 01Open the template below and find the cells the rule reads.
  2. 02The two values must be the same. Find which of the two is right, and correct the other one.
  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
Cumulated net contractual gap1,200
What the rule then expects

Net contractual gap must then be 1,200.

1,200Passes
1,300Fails

A file that reports 1,200 passes. One that reports 1,300 fails, by 100.

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