How the Ledger is kept
- Every row is a deal read in its source, and links to that source.
- Every row says what kind of document it comes from: a regulatory filing, the company’s own release, an earnings call, or a news report. A news report stays a news report until a filing confirms it.
- Values are the headline figures as the parties disclosed them, in US dollars, unadjusted. “Undisclosed” means they did not say.
- The end date is the start plus the term, worked out here — it is not a reported figure.
- Facts only. The Ledger holds no view on any deal.
