The date that binds, not the date on the notice.
Voluntary events are decided by a clock, and the clock moves. An offer that is extended does not add a second expiry here — it supersedes the first, because a calendar that still shows a date somebody already changed is worse than no calendar at all. Each row names the filing the date was read from.
What is not here yet
These are issuer deadlines — the dates in the offer document. The deadline that actually binds a holder is the broker’s or custodian’s internal cut-off, which is earlier, is not filed anywhere, and arrives by email. Holding those two against each other is the enterprise half of the product.
Nothing falling in that window yet.
Derived from public SEC EDGAR filings. Extraction from prose is heuristic and carries a confidence; every figure links to the document it was read from. Not investment, legal or tax advice.
