Filed as Carroll David William (35)

48 transaction lines · from 35 filings · filed 2016-11-04 to 2019-01-24 The span is the filing dates this catalog holds, not the entity's full filing history. Absence here is not evidence of absence at the SEC.

How this page attributes a trade

A line appears here when the filing that carries it names this CIK as a reporting owner, not only when the parser picked this CIK as the line's primary owner. That is why a joint filing appears on both owners' pages rather than vanishing from the second one. The catalog never merges two CIKs into one person and never splits one CIK into two: identity here is the SEC's own identifier and nothing else.

01

Issuers this insider has filed against

No issuer is recorded

02

This column is intentionally blank

No transaction line is stored for this reporting owner, though the catalog holds filings naming them. That happens when the filings report only holdings or only positions the store does not carry, and when a parse failed; each filing page states its own parse status.

Every value is as reported on the Form 4, totalled to the dollar. Share counts, the price per share and the full list of reporting owners are on each filing's own page, which every row here opens. A row marked n lines adds up that many filed lines of one filing, on one day, on one side of the market; a filing whose lines fall across two pages is left as its lines on both, so no total here is ever short.

What this insider's stored lines contain

Exact counts over every stored line for this entity. This is a statement of composition, not a filter: the only filter this page offers is the open-market one above, because that is the only one an index serves today.
