2 min readWarningEBA reporting framework 4.2Updated 10 November 2026

Total exposures must equal the sum of its 16 parts (EBA rule v6050_m)

A warning in the own funds and capital requirements return (COREP own funds), on template C 09.01.a, geographical breakdown of exposures by residence of the obligor (SA exposures).

Check your file against this ruleWhat to do if it fails

The rule in plain words

Total exposures must equal these 16 added up:

  • Central governments or central banks
  • Regional governments or local authorities
  • Public sector entities
  • Multilateral development banks
  • International organisations
  • Institutions
  • Corporates
  • Retail
  • Secured by mortgages on immovable property and ADC exposures
  • Exposures in default
  • Subordinated debt exposures
  • Covered bonds
  • Claims on institutions and corporate with a short-term credit assessment
  • Claims in the form of CIU
  • Equity exposures
  • Other exposures

EBA checks it for ten columns, from original exposure pre conversion factors (0010) to risk weighted exposure amount after supporting factors and after FX-mismatch (0090). That makes ten 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.

Additional value adjustments and other own funds reductions: Total exposures = Central governments or central banks + Regional governments or local authorities + Public sector entities + Multilateral Development Banks + International Organisations + Institutions + Corporates + Retail + Secured by mortgages on immovable property and ADC exposures + Exposures in default + Subordinated debt exposures + Covered bonds + Claims on institutions and corporate with a short-term credit assessment + Claims in the form of CIU + Equity exposures + Other exposures

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  3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.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 09.01 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.
