About these balances

Latest available filing per company, not a reconstructed current portfolio. Matching sequences show the last reported balance with all source rows expandable; grouping alone does not establish account ownership. Do not add unresolved positions together. Filings may omit unchanged positions, and amendments may correct only part of an older disclosure. Jointly reported shares are not necessarily this owner's personal holdings.

No balances currently tracked through insider filings.

Past disclosures · reporting ended (1)

No longer tracked through insider filings. These historical balances do not imply present ownership or a zero position.
