"Disclosed insider exposure" sums this person's most-recently-reported share counts across each company they're an insider in, multiplied by the current underlying price. It is not net worth — it misses retail holdings, private investments, real estate, index funds, and any company where the person isn't an SEC-reporting insider. For informational purposes only.

Notice (144 / 144/A): Form 144 is a notice of intent to sell restricted/control stock under Rule 144, filed before the sale; 144/A is an amendment, and an amended or cancelled notice is not listed. Many notices are pre-scheduled under Rule 10b5-1 plans. A Form 4 with code S typically follows within a few days when the planned sale executes. Someone who is no longer an officer or director (or never was) files no Form 4, so for them a sale shows up only on a later notice, which lists the seller's sales from the 3 months before it. "No sale on file" means neither record shows one; a dash in Net $ means the value filed on the notice doesn't fit the stock's price (likely a typo).
