Reminder: I'm an accountant.
I did some research on this a few months ago. This Thread contains my conclusions.
@Startrekangel No the WTBS does not own the O'Rielly trust. That trust is a separate entitiy that belongs to Ms O'Reilly's estate. It is managed for the benefit of the WTBS, but they don't have any say in how its run. These things are regulated by US law, which doesn't care what the Watchtower says in its magazines.
On both of these issue I don't think there is anything here for the XJW community. There are much bigger fish to fry: pedophiles, the theft (in my opinion) of local funds and kingdom hall ownership, misappropriation (probably) of donations, and who knows what went on in the construction of Warwick.
Citizenofearth: congratulations on doing your research. I expect you'll find you can't go back.
