Preserve the relationship between a reported position, its contributing records and the business context that explains a change.
Legal entities and reporting scopeA counterparty position may change because of new transactions, revised entity mappings, valuation inputs or the reporting cutoff. The contributing records help a reviewer distinguish new activity from a correction or a changed definition.
| Source context | Review purpose |
|---|---|
| Account and counterparty records | Establish the reporting entity relationship |
| Transaction history | Explain activity and corrections |
| Valuation or risk output | Identify methodology and calculation time |
| Control evidence | Show review status and unresolved issues |

A financial institution may hold account, counterparty and product information across several business units and legal entities. A group relationship does not necessarily determine how an exposure should be reported. The correct view depends on the purpose, reporting perimeter and applicable risk methodology.
An enterprise intelligence model can connect those records while preserving their source authority. Legal entity, counterparty, account, instrument and transaction relationships need explicit definitions and effective dates. Investigators should be able to see the contributing records behind an aggregate rather than relying on a total without context.

Relevant sources can include account systems, transaction processing, the general ledger, customer records, collateral systems and risk calculations. Each has its own timing and correction behavior. A settled transaction, an unsettled commitment and a modeled exposure should remain distinct in the connected view.
BCBS 239 sets out principles for banks' risk data aggregation and internal risk reporting. Accuracy, completeness and reporting governance are central to understanding the records behind a reported position.

Financial information often crosses distinct confidentiality and entitlement boundaries. Apply permissions to source records and derived views, including any evidence assembled for an investigation. A connected relationship should not grant access to every record associated with an entity.
Retain the version of definitions and source records used in a reviewed report. Corrections after a reporting cutoff need an explicit treatment. This allows a reviewer to explain both the earlier position and the later change without silently rewriting the evidence.
Late adjustments, currency movements and changes in entity structure can all alter a reported position. The reporting date and the definitions in force at that date determine how those changes should be understood.
Keeping original and corrected records together helps reviewers explain a reconciliation break and identify whether it came from new activity, a revised calculation or a change in reporting scope.
