Context: For most retail investors, insider purchases are more informative than routine sales. This report documents a straightforward open-market sale by a non-executive director; it does not by itself reveal the insider’s broader intent or company outlook. If you need the exact per-trade breakdown within the reported price range, the footnote indicates that information can be requested from the issuer or the SEC staff.
