Money frankly is irrelevant beyond a certain point (and most of it is in the form of share holdings anyway).
I'd be more worried about the power/political influence these individuals wield. There is generally an incestuous coterie of the rich that one gets access to after a certain point, where the destruction of freedom is lubricated with champagne and caviar. Bildeberg/IMF/WTO/G20 etc. are symptomatic of such cabals of corporatocracies and their retainers in the state apparatus that wield power over the world.
Universities, and I would guess charities as well, tend to liquidate their shares immediately to avoid conflicts of interest. Liquidating that many shares that fast would cause havoc in the markets.
