Signed proof documents for official exchange rates

Keep source attribution, selected date, document id, payload hash, and public verification together.

Evidence workflow

Exchange-rate proof for audit workpapers

Attach one signed exchange-rate proof PDF to the audit workpaper, then let the reviewer inspect the source and rate context and use the public verification details in that same file.

From the first question to reviewer follow-up

How do I attach exchange-rate proof to an audit workpaper?

Attach the Signed FXProof Proof PDF to the workpaper that contains the rate-dependent calculation. The PDF already contains its source/date/rate context, document id, payload hash, digital signature, and verification information.

Keep any audit conclusion or explanation of source selection in the workpaper itself. FXProof supplies the exchange-rate proof document, not the audit conclusion.

What can the reviewer verify?

The reviewer can inspect the proof PDF without access to the preparer account.

  • Source attribution and source date.
  • Rate context used in the calculation.
  • Embedded digital signature.
  • Document id and payload hash for the public FXProof check.

What FXProof does not decide

FXProof does not decide whether the rate choice, workpaper conclusion, or evidence package is appropriate. Acceptance depends on the auditor, procedure, and jurisdiction.

Before fieldwork

Attach proof PDFs to the rate-dependent workpapers before questions arrive.

Questions

How do I attach the proof PDF to an audit workpaper?

Attach the Signed FXProof Proof PDF to the workpaper that contains the rate-dependent calculation. Its FXProof proof and verification fields are already inside the PDF.

What can an auditor verify?

The auditor can inspect the source and rate context, validate the embedded digital signature, and use the document id and payload hash shown in the PDF on the public check page.

Does FXProof guarantee audit acceptance?

No. FXProof provides a source-attributed proof document. Acceptance depends on the auditor, procedure, and jurisdiction.

Keep the proof with the file that used the rate

Inspect a static sample first, then use an account when you need a proof bundle for a concrete dataset and date.
