What changed on 1 September 2026

Also on the diary

9 dated events this weekWhat to do about them

A long-stop is the charter’s outside date for completing a combination. It pays nothing: the trust comes back only if no deal closes by then. The window to hand shares back for cash has already closed on these — there is nothing left to claim at the date shown.

Deals


Nothing to report. No deal announcements, votes, approvals or terminations are dated inside this window.

How this brief is made


  • Composed deterministically from stored primary-sourced rows — no LLM, no live fetching of facts, $0 per run.
  • Trust NAV accreted at the 3-mo T-bill par yield 4.00% (treasury.gov, 2026-09-10); accreted values are ESTIMATES and labeled as such.
  • Broker action dates count ~2 real NYSE trading days before the deadline (weekends and market holidays excluded) — still verify with your broker, whose cutoff may be earlier.
  • 20 filings were scanned for this window.
  • Items tagged "coverage" are database-ingestion events (a row was captured), not market events — the underlying facts may predate the window.
  • Dated events are summarised on this page and never turned into an instruction. An outside date is the contractual long-stop: it pays nothing, and the trust comes back only if no combination closes. Where the record holds no dated redemption event either way, the page says so instead of assuming one.

Every figure on this page is taken from a filing with the U.S. Securities and Exchange Commission and links to it. Estimates are labelled as estimates. Prices are last trades, not quotes. This is information, not investment advice.

This is a dated edition — the record of one day, kept at its own address. Editions are retained for 60 days.
