Source and assumption register

A practical register connecting each material TP statement to its source, owner, status and review decision.

01

What the register controls

A source register prevents factual statements, policy assumptions and professional judgments from being mixed together. Each material statement receives an evidence status and an accountable owner.

02

Minimum fields

  • Statement or analytical proposition.
  • Source document, interview or financial dataset.
  • Period and legal entity covered by the source.
  • Status: confirmed, assumed, disputed or missing.
  • Reviewer decision and required follow-up.

03

Use in a Local File cycle

Carry forward only sources that still cover the relevant period and operating model. Reconfirm assumptions when agreements, personnel, cost pools, risks or transaction values have changed.
