2 min readWarningEBA reporting framework 4.2Updated 10 November 2026

C 18.00 (sheet 0001) must equal the sum of its 22 parts (EBA rule v6270_m)

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.

The rule in plain words

C 18.00 (sheet 0001) must equal these 22 added up:

  • C 18.00 (sheet 0008)
  • C 18.00 (sheet 0009)
  • C 18.00 (sheet 0023)
  • C 18.00 (sheet 0020)
  • C 18.00 (sheet 0016)
  • C 18.00 (sheet 0024)
  • C 18.00 (sheet 0003)
  • C 18.00 (sheet 0025)
  • C 18.00 (sheet 0022)
  • C 18.00 (sheet 0019)
  • C 18.00 (sheet 0018)
  • C 18.00 (sheet 0017)
  • C 18.00 (sheet 0021)
  • C 18.00 (sheet 0012)
  • C 18.00 (sheet 0007)
  • C 18.00 (sheet 0015)
  • C 18.00 (sheet 0014)
  • C 18.00 (sheet 0005)
  • C 18.00 (sheet 0002)
  • C 18.00 (sheet 0013)
  • C 18.00 (sheet 0006)
  • C 18.00 (sheet 0004)

All the values are in the positions subject to capital charge column (0050) of C 18.00.

EBA checks it for eleven rows, from maturity-based approach (0020) to rated nth-to default credit derivatives (0321). That makes eleven 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.

Positions subject to capital charge: Debt securities under the first category, Total = Debt securities under the first category, Forint + Debt securities under the first category, Yen + Debt securities under the first category, Norwegian Krone + Debt securities under the first category, Hryvnia + Debt securities under the first category, Serbian Dinar + Debt securities under the first category, Egyptian Pound + Debt securities under the first category, Lek + Debt securities under the first category, Other + Debt securities under the first category, Iceland Krona + Debt securities under the first category, Turkish Lira + Debt securities under the first category, Swiss Franc + Debt securities under the first category, Swedish Krona + Debt securities under the first category, US Dollar + Debt securities under the first category, Denar + Debt securities under the first category, Pound Sterling + Debt securities under the first category, Russian Ruble + Debt securities under the first category, Romanian Leu + Debt securities under the first category, Czech Koruna + Debt securities under the first category, Euro + Debt securities under the first category, Zloty + Debt securities under the first category, Danish Krone + Debt securities under the first category, Bulgarian Lev

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 row, 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.
