Securities lending and repos: far leg amount must be reported whether buyer or seller in repo is reported in Position in the Contract item (S.10.01, EIOPA rule BV1590)

A blocking check on the securities lending and repos template (S.10.01), in the annual solo (ARS) and annual branch (ARB) returns.

It applies to 2.8.2 returns too, the release for the 2026 returns, and Line4 Check runs it there as well.

The rule in plain words

Far leg amount must be reported whether buyer or seller in repo is reported in Position in the Contract item

What to do if your return fails it

  1. 01Open the table below and find the cells the rule reads.
  2. 02The check applies only when its first part holds in your return. When it does, the second part must hold too: fix the second part, or correct the first.
  3. 03It runs only when your filing indicators mark S.10.01 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
