Several footnotes indicate the shares were held or sold by trusts (revocable and various remainder/GRAT trusts) for which Bergman serves as settlor, trustee, or investment advisor — some transfers changed the form of beneficial ownership from direct to indirect (see F2, F4, F6–F10).
• Price reporting: Some reported prices are weighted averages across multiple executions; full per-trade price breakdowns are available from the filer upon request (see F3/F5).

Context

• These are sales (often routine), and the filing indicates they were executed under a pre-established 10b5-1 plan, which is commonly used to automate insider sales and reduce timing risk. Several sales involved trusts where Bergman has control or advisory roles; transactions by such trusts can reflect estate or tax/estate-planning actions rather than a direct change in economic exposure. The late filing (filed 5 days after the trades) is noted; investors who track insider timing may factor that in.
