Context

Code J and $0.00 entries typically reflect non‑cash transfers (internal reassignments, record-level transfers, or securities lending activity) rather than open‑market buys or sales. Footnotes here point to managed-account ownership and securities lending as the reason for the reported transfers.
These entries do not indicate a conventional buy or sell decision by the director in the open market; they reflect changes in how the securities are held or recorded.
