It depends on whether they are a "wholly owned subsidiary" or just a subsumed entity. Since they were acquired in 2010, you might have to go back and read those fins if interested. I think they are just a named entity with no assets or revenue, a holding company (LLC) as a buffer zone for trading and protection, would be my guess. I believe that entity is just a place to park shares. If I remember correctly (and I could be wrong about this), as the spouse of Bill, NOT a named employee, and the head of another "company" she can trade shares without filing paperwork, just as you and I can.
