Data Sources

Every figure on The Accidental Order comes from one of four sources. This page records which source each field comes from, and how any number can be traced back to the document it was taken from.

The four sources

Each data file carries the source name in its own source field.

Every figure traces to a receipt number

Values taken from filings carry a 14-digit receipt number. The first eight digits are the receipt date; the rest is that day’s sequence. For example, 20260826000626 is a document received on 26 August 2026.

Searching that number on DART opens the form the figure was written on. Any cell in a table can be checked against the document it came from. Articles print the receipt number alongside each figure they quote.

If a filing does not contain the number, the cell is left empty. It is not filled with an estimate. An empty cell often carries a note explaining why the value could not be closed — for instance, when financial liabilities are not named as borrowings and net cash cannot be settled.

Prices carry a delay

Share prices come from public data and are not real time. Each figure carries its own base date, and that date is printed on screen. When a label reads “as of the 25 Aug close”, the number belongs to that date.

Macro indicators differ from one another in the same way. Indices are the previous session’s close, the exchange rate is same-day, and the base rate is as of its last change. Indicator tables therefore carry a separate as-of column.

How the figures are calculated

Which value was divided by which denominator, and what was included or excluded, is set out in the data room methodology. Two ratios with the same name produce different numbers when the denominator differs, so that definition is the place to start.

If something in the figures looks wrong, please tell us through Report an error. Because each value carries a receipt number, it can be checked against the original document.
