A friend of mine used to be wealthy. Ranked at #8 in the world, he dismissed fears the investment community had about one of his business projects, saying that if it turned south he would bail it out with his own assets.
The problem was, when it turned south, his $30 billion of assets also disappeared and his creditors had zero recourse. In this case, he didn’t so much sell his shares as simply had them dissolved away (it was some of both, in fact).
I have mentioned this before but the joke almost bears worth repeating. I’m now worth $1 billion dollars more than he....not because my TSLA has done
that well but because his net worth is now -$1 billion.
@jbcarioca can confirm the generalities of that little story.
The takeaway is not, of course, that Mr Musk is a Mr EB, but that his shares are not encumbered: they are a part of free float.
