A Form 144 is the notice an insider files with the SEC before selling restricted or control shares over the Rule 144 thresholds; it says what may be sold, not what was.
Read moreValue is the filer's own aggregate market value. Sold, per Form 4: the same seller's open-market sales on Form 4 from the notice's date to 90 days after, added up, as they appear on the insiders page; a holder who files no Form 4, such as some large holders, never shows one.
