About this data

Figures are parsed from SAMBERG JOSEPH D's Form 4 filings on SEC EDGAR (CIK 1264542) and cover open-market purchases (transaction code P) — grants, option exercises, and sales are excluded, which is why totals here can differ from raw filing counts. Every row links to its source document.

This page is informational and reflects public filing data. It is not investment advice.
