The same rule on both sides. Where attribution is unpublished the read abstains, states why, and gives you a conservative default you can still file.

03 · The risk side

You carry the loss. The seller wrote the file.

Four seats, each defending a number to someone stricter: a reinsurer, a credit committee, an auditor, a board.

You underwrite it.

Your own model cannot validate your own book to a reinsurer.

You lend against it.

Your credit committee has no independent mark on the collateral.

You mark it.

Your auditor will ask where the number came from.

You sign it off.

From FY2028 US GAAP marks what you still hold, every reporting date.

04 · Method

Four rules.

Nothing originates from a model.

Every figure comes from a source document or a calculation over source documents.

Verifiable, not trusted.

Provenance is timestamped externally. Check any number without believing us.

Abstention over estimation.

Where attribution is unpublished, the record says so.

Paid by the risk side.

Never the seller. No placement fees, no trading, no title.
