2 min readWarningEBA reporting framework 4.2Updated 10 November 2026

Net positions: debt securities under the second category must equal the sum of its three parts (EBA rule v903147_h)

A warning in the own funds and capital requirements return (COREP own funds), on template C 18.00, market risk: standardised approach for traded debt instruments.

Check your file against this ruleWhat to do if it fails

The rule in plain words

For net positions: debt securities under the second category must equal these three added up:

  • With residual term <= 6 months
  • With a residual term > 6 months and <= 24 months
  • With a residual term > 24 months

EBA checks it for six columns: long (0010), short (0020), long (0030), short (0040), positions subject to capital charge and own funds requirements. And on 23 sheets, from total (0001) to other (0025). That makes 138 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.

Short: Debt securities under the second category, Swedish Krona = With residual term <= 6 months, Swedish Krona + With a residual term > 6 months and <= 24 months, Swedish Krona + With a residual term > 24 months, Swedish Krona

What to do if your filing fails it

  1. 01Open the template below and find the cells the rule reads.
  2. 02Add up the parts in your file and compare the result with the total.
  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
  4. 04EBA allows a small rounding difference, worked out from the decimals each value is reported with.
  5. 05It runs only when your filing indicators mark C 18.00 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.

A worked example

The first of its checks, with simple numbers.

Illustrative values
With residual term <= 6 months1,200
With a residual term > 6 months and <= 24 months800
With a residual term > 24 months450
Together2,450
What the rule then expects

Debt securities under the second category must then be 2,450.

2,450Passes
2,550Fails

A file that reports 2,450 passes. One that reports 2,550 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_18.00,r0270,c0040,s0017} = {C_18.00,r0280,c0040,s0017} + {C_18.00,r0290,c0040,s0017} + {C_18.00,r0300,c0040,s0017}

The next five:

{C_18.00,r0270,c0020,s0024} = {C_18.00,r0280,c0020,s0024} + {C_18.00,r0290,c0020,s0024} + {C_18.00,r0300,c0020,s0024}{C_18.00,r0270,c0010,s0016} = {C_18.00,r0280,c0010,s0016} + {C_18.00,r0290,c0010,s0016} + {C_18.00,r0300,c0010,s0016}{C_18.00,r0270,c0060,s0022} = {C_18.00,r0280,c0060,s0022} + {C_18.00,r0290,c0060,s0022} + {C_18.00,r0300,c0060,s0022}{C_18.00,r0270,c0020,s0007} = {C_18.00,r0280,c0020,s0007} + {C_18.00,r0290,c0020,s0007} + {C_18.00,r0300,c0020,s0007}{C_18.00,r0270,c0020,s0021} = {C_18.00,r0280,c0020,s0021} + {C_18.00,r0290,c0020,s0021} + {C_18.00,r0300,c0020,s0021}

And 132 more, the same formula for the other cells it covers.
