Methodology
Corporate-action classification
Events are typed, then each venue's treatment is looked up separately.
Updated 2026-09-25
Supported types include cash dividends, special dividends, stock dividends, splits, reverse splits, rights issues, spin-offs, mergers, tender offers, delistings, halts, ETF distributions, index changes and listing transitions.
Where a venue has not published a treatment, the cell says so. It is not filled with the treatment used by a different venue. Scenarios in the demonstration calendar are labelled scenario and are not issuer announcements.
