What does code J mean on Form 4?
Code J means “other acquisition or disposition,” and the filer must describe the transaction. J is deliberately broad, so the A/D marker and Explanation of Responses are essential to any accurate summary.
What code J means
Other acquisition or disposition (describe transaction)
The filer used the catch-all code because no listed transaction code specifically described the event.
- The official fallback code when the transaction is not specifically listed in Instruction 8.
- A classification that can cover either an acquisition or a disposition.
- A code paired with a required description of the transaction in the Explanation of Responses.
What code J does not mean
- One universal economic event with a standard market interpretation.
- A substitute for the A/D marker, security type, ownership form, or surrounding rows.
- Evidence that the filer concealed something; the category exists because the standard list is not exhaustive.
How code J appears on Form 4
The transaction row carries J while the A/D column identifies which direction the security moved.
The Explanation of Responses should describe the nature of the otherwise unlisted transaction.
Related entries can still appear in Table I or Table II, so dates and security titles must be joined with the narrative.
Common event shapes involving code J
An unlisted acquisition with an explanation
The A marker establishes direction; only the filing’s description can identify the acquisition’s actual mechanics.
An unlisted disposition with an explanation
A D marker does not make the event a code-S sale. Read the narrative before selecting ordinary market language.
A catch-all leg inside a broader sequence
Match transaction dates, security titles, ownership, and footnote references to determine how the J row connects to the rest of the filing.
Common misreads
- Treating J as though it always means an ordinary sale or an uncategorized purchase.
- Skipping the explanation because the direction column appears self-explanatory.
- Assuming “other” signals a problem instead of checking the transaction the filer actually described.
Questions to ask next
Is the J row marked acquired or disposed?
What exact transaction does the Explanation of Responses describe?
Which security moved, at what amount and price, and through what ownership form?
Do other rows share the same date, security, or footnote reference?
Would calling the event a purchase or sale add a fact the filing does not state?
No selected Buteon Case File is used for code J
The current public Case Files do not provide a clean, verified code-J example. This page therefore stays with the official mechanics instead of borrowing or inventing a transaction.
- Instruction 8 says to use J when a transaction is not specifically listed.
- The filer must describe the nature of the transaction in the Explanation of Responses.
- A future example should be added only after its primary filing has been reviewed and the description can be preserved accurately.
No current published Case File contains a clean code-J event suitable for a worked example.
Code J FAQ
Why would a filer use code J?
Instruction 8 directs the filer to use J when the transaction is not specifically listed among the other codes and to describe its nature.
Can code J be an acquisition or a disposition?
Either. The A/D marker provides direction, while the explanation identifies the event.
Does code J mean the transaction was unusual or suspicious?
No such conclusion follows from the code. J only says that another listed code did not specifically describe the transaction.
Can I understand code J without reading the footnotes?
Not safely. Read the Explanation of Responses and any referenced footnotes or related rows before assigning a plain-English label.
