Subject: Re: BRK.B performance vs Price/Book
Is there a published or relatively easily calculable alternative to book for estimating IV and/or its changes over time?

Buffett did not give a formula for intrinsic value but he broadly outlined how to think about it. There are two main items that contribute to intrinsic value of BRK: (1) Net cash + investments per share, and (2) Normalized non-insurance operating earnings (excludes insurance u/w profit or loss, and investment income). This is commonly known as the "two column method". The first column is self explanatory and one can make an allowance for deferred taxes which may be at least partly payable at some point. The second column involves an estimate of business value of non-insurance subs run by Greg.
