I thought this meant it was $500 billion in government money.

Some of these companies do have huge cash reserves they don't know what to do with so if it is $500 billion of private money, I am not going to complain.

I will believe it when I see it though and that this isn't a 100 billion in private money with a 400 billion dollar free US government put option for the "private" investors if things don't go perfect.
