Derrickson Ralph C

CIK 0001313602 Name as filed on the most recent filing

Filed as Derrickson Ralph C (14)

20 transaction lines · from 14 filings · filed 2013-11-26 to 2023-05-24 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

Ordered by last-seen filing date, newest first. Roles are as filed on the Form 4 and are not normalised.

Fault

This container could not be filled from the store. It is showing nothing because a read failed, not because no insider filed: those are different facts and this catalog will not let one stand in for the other. The last ingest the store recorded was 2026-08-20 05:22 UTC.

No issuer is recorded

The catalog holds no filing linking this CIK to an issuer.

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.

Codes on this page
P, Open-market purchase
Open-market purchase
S, Open-market sale
Open-market sale

Every value is as reported on the Form 4. A price the filing did not report is marked Not reported and no value is computed from it. Codes outside the open market, drawn in grey behind a dashed rule, are compensation and administrative machinery rather than a decision to trade at the prevailing price.
