Subject: Re: Portfolio percentage
In a tax sheltered account I'd go to 100% with the price at book, and 0% with the price at twice book.

So, at current book $337.15 and share price $498.66:

100% BRK.B at $337.15 (P/B 1.00) and 0% cash.
 75% BRK.B at $421.44 (P/B 1.25) and 25% cash.
 50% BRK.B at $505.73 (P/B 1.50) and 50% cash.
 25% BRK.B at $590.01 (P/B 1.75) and 75% cash.
  0% BRK.B at $674.30 (P/B 2.00) and 100% cash.

Seems like a nice little fund. How much AUM can I get for this at 2 and 20?
