Subject: The Excess Cash
I know that Berkshire likes to keep a good amount of cash on hand in case sudden good deals pop up. That's usually about $100B or so. But now there is double that amount (more or less). I wonder if Buffett is doing this purposely because he knows he will soon die (Anyone that age is likely to soon die!) and perhaps there is some reason a bunch of that cash will become necessary, perhaps to buy back most of his shares so the various foundations can hold diversified things instead of only (or mainly) Berkshire stock?
