  - `listingNotice` ListingNotice: What happened to a requested ticker that no longer trades. "delisted": the company has no current US listing, so the answer is its history. "renamed": the company now trades as successorTicker, its current US presentation ticker (possibly another share class). A listed series (short volume, short interest, off-exchange volume, fails-to-deliver, congressional trades) is the retired ticker's own; a company-level read is the company's data.

  - `ticker` string, nullable: The listed ticker read: the requested ETF series or share class, or the company's primary listing.

      - `country` string, nullable: The EDGAR state or country code of the holder's address; null when unknown.
      - `shares` integer: Shares restated onto today's split basis; 0 for a row that states only votingRightsPercent.

      - `percentOutstanding` number, double, nullable: Restated shares as a percentage (0 to 100) of the issuer's shares outstanding; null when that is unavailable (see percentUnavailableReason).
      - `filedPercentOfClass` number, double, nullable: The percent of class the disclosure itself states (a 13D or 13G cover page), or a non-US major-holding notification's percentage of voting rights or, for a Canadian report, of the class, which states no share count; null otherwise.

      - `notSummed` boolean: The ownership summary does not add this row's shares: funds, nested rows, and holders a 13F report already holds.

      - `purpose` StatedPurposeDto: The purpose a Schedule 13D states in Item 4 ("Purpose of Transaction").
        - `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).

        - `categories` StatedPurposeCategoryDto[], nullable
          - `token` string, nullable: A stable token for the purpose: ControlOrBoard, StrategicAlternatives, CapitalReturn, MergerStance, PassiveInvestment or Other.

          - `quote` string, nullable: The filing's own sentence stating it.
      - `childCount` integer: How many rows nest under this one in the default view; children lists at most 25 of them.
