I will take a longer look at these documents when I get a minute. My initial impression of the Henrietta Riley documents is that some time five to ten years ago that entity divested itself of some or all of the problematic stocks.
It is impossible to know if that was in response to criticism from places like this board or something else. The Watchtower has done a good job of hiding its money from any accountability.
When I was first becoming a JW I did a simple calculation. At that time the society was printing about ten million copies of every issue of the Watchtower and Awake, which they sold for 25 cents, essentially these cost free as they used slave volunteer labor, and magazines were paid for by the publishers when picked up at the hall. This works out to something north of a hundred million dollars a year.
Plus all the other stuff. When I asked an elder what they did with the money I got some blah blah blah about the world wide work. Fortunately I fifteen years later I left.
