title: "An institution's Schedule 13D and 13G stakes: its latest 13D or 13G on each listed security it ever disclosed, held stakes first and newest event first, with the event and filing dates, the shares (restated onto today's split basis) and percent of class, the change since the filer's previous filing on that security, a 13D's Item 4 purpose where read, and a status: current; unconfirmed (no filing in 24 months; a 13D or 13G stays in force until amended, so the stake is kept and never assumed sold); below_threshold (the latest filing reports under 5%, the amendment that ends the filer's duty to amend, not necessarily the holding); exited (no shares); or security_retired (the issuer no longer trades in the US). The default view lists current and unconfirmed stakes; view=all adds the rest. These are event-dated 5% stakes, never a quarter-end portfolio: the 13F book is under v1/institutions/{cik}/portfolio. A filer that files only 13D or 13G resolves by CIK like any other."

  - `hiddenCount` integer: Stakes the default view leaves out: reported below 5%, exited, or on a security that no longer trades.

    - `ticker` string, nullable: The ticker the stake was filed on: the exact class or unit, else the issuer's presentation ticker.
    - `currentTicker` string, nullable: The issuer's presentation ticker today; null when the issuer has no listing on record.

    - `rules` string[], nullable: The Rule 13d-1 paragraphs a 13G is filed under: 13d-1(b), 13d-1(c) or 13d-1(d); empty for a 13D.

    - `hasCoverPage` boolean: False for an older filing whose cover pages were never read.
    - `status` string, nullable: current; unconfirmed (no filing in 24 months; the schedule stays in force, so the stake is kept and never assumed sold); below_threshold (the latest filing reports under 5%, the amendment that ends the filer's duty to amend, not necessarily the holding); exited (no shares); or security_retired (the issuer no longer trades in the US).
    - `delistedOn` string, date, nullable: The day the issuer's listing stopped trading, when known.

      - `state` string, nullable: stated (categories lists each purpose), none_stated (Item 4 states none of the classified purposes) or not_restated (an amendment that does not restate Item 4, so the earlier 13D's purpose stands).
