Corrections policy
A filing can be amended after it is published. When that happens the card we published is not deleted, and it is not edited in place. It stays at its own address, marked superseded, and links forward to the card that replaces it; the replacement links back. Both remain part of the record.
The mechanism
What happens when a filing is amended
Every card has a permanent address of its own. When a source publishes an amendment to a filing we have already carded, the amendment is ingested as a new card and the original is marked superseded rather than overwritten. The feed, the archive and the per-entity pages carry the current version — the record as it now stands — and the superseded card remains reachable at its address forever, stating that it was amended and linking to what replaced it.
This is why a card’s address is safe to cite: the citation format points at a version, and a correction adds to the record rather than rewriting the page someone quoted.
A worked example, from the live data
An amended Form 4
On 2026-04-22 an AGCO insider filed a Form 4 reporting 1,960 shares. On 2026-08-11 an amendment restated the same transaction as 1,604 shares. Both filings are published:
- The original card (accession 0001581064-26-000011) — marked superseded, linking forward.
- The amendment (accession 0001581064-26-000015) — the current version, and the one the feed carries.
The superseded card is deliberately absent from the archive and the feeds, which carry the record as it now stands, and deliberately present at its own address, which is what makes an earlier citation still resolve.
What we do not do
Two things this policy rules out
We do not rewrite a published card in place, and we do not remove one because it turned out to be wrong. A publisher whose claim is fidelity has to leave the record of its own errors intact — a card that quietly changed would make every other card unverifiable.
If you believe a card misstates its source document, the source document is linked on the card itself; that link is the thing to check first, and it is the thing we correct against.
