B_03.01 — Entities signing arrangements
Purpose
This template records which financial entities are signatories to each ICT contractual arrangement. A single contract may have multiple financial entity signatories (e.g., when a group-wide contract is co-signed by several subsidiaries).
Each row represents one entity-to-arrangement signing relationship. This allows regulators to understand which entities are legally bound by each contract and can exercise contractual rights such as audit clauses or termination.
The legal or procurement team maintains this template alongside B_02.01 whenever contracts are signed or amended.

Common Mistakes
- Missing signatories for arrangements. Every contract in B_02.01 must have at least one corresponding entry here. Contracts without signatories indicate incomplete data.
- Invalid LEI for signatory. The LEI must match an entity in B_01.01 (for IND) or B_01.02 (for CON reporting). Using a provider LEI here is incorrect — providers sign via B_03.02.
- Duplicate signatory rows. The same entity should not be listed twice as a signatory for the same arrangement.
