I've been researching the "real money".
One time I stayed at Bethel in a Co-Hi apartment, an apartment that Co-Hi had retained for personal use. At the time money freely flowed back and forth between private corps and WTBTS. This bothered me at the time even though the explanations made sense. With WTBTS being broken up in '00 the structure is much more complicated. Which I'm sure is the intent. Since these corps are private its hard to follow the paper trail. I don't have a complete answer but its apparent that capital is being held external to the Org.
