If a sum of seven columns is more than zero, total event types cannot be less than a sum of seven columns (EBA rule v4861_m)

A warning in the own funds and capital requirements return (COREP own funds), on template C 17.01.a, operational risk: losses and recoveries by business lines and event types in the last year.

Check your file against this ruleWhat to do if it fails

The rule in plain words

If these seven worked out is more than zero, total event types cannot be less than internal fraud plus external fraud plus employment practices and workplace safety plus clients, products & business practices plus damage to physical assets plus business disruption and system failures plus execution, delivery & process management:

  • Internal fraud
  • External fraud
  • Employment practices and workplace safety
  • Clients, products & business practices
  • Damage to physical assets
  • Business disruption and system failures
  • Execution, delivery & process management

EBA checks it for two rows, all for (new events): number of events and gross loss amount. That makes two 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.

If Gross loss amount (new events), INTERNAL FRAUD + Gross loss amount (new events), EXTERNAL FRAUD + Gross loss amount (new events), EMPLOYMENT PRACTICES AND WORKPLACE SAFETY + Gross loss amount (new events), CLIENTS, PRODUCTS & BUSINESS PRACTICES + Gross loss amount (new events), DAMAGE TO PHYSICAL ASSETS + Gross loss amount (new events), BUSINESS DISRUPTION AND SYSTEM FAILURES + Gross loss amount (new events), EXECUTION, DELIVERY & PROCESS MANAGEMENT > 0, then Gross loss amount (new events), TOTAL EVENT TYPES >= Gross loss amount (new events), INTERNAL FRAUD + Gross loss amount (new events), EXTERNAL FRAUD + Gross loss amount (new events), EMPLOYMENT PRACTICES AND WORKPLACE SAFETY + Gross loss amount (new events), CLIENTS, PRODUCTS & BUSINESS PRACTICES + Gross loss amount (new events), DAMAGE TO PHYSICAL ASSETS + Gross loss amount (new events), BUSINESS DISRUPTION AND SYSTEM FAILURES + Gross loss amount (new events), EXECUTION, DELIVERY & PROCESS MANAGEMENT

What to do if your filing fails it

  1. 01Open the template below and find the cells the rule reads.
  2. 02The check applies only when its first part holds in your file. When it does, the second part must hold too: fix the second part, or correct the first.
  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 17.01 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.
