I'm trying to come up with a relatively long-term (20 years or so) history of BRK Intrinsic Value per BRK.B share. From all I've seen here, including comments by Jim, a multiple of Book Value per B share is still a somewhat reasonable, though perhaps a bit crude, way of deriving IV. If that's correct, then I need a table of BV per BRK.B share, and an appropriate IV multiplier. I suppose the multiplier could change over time, but I hope not.

In looking for a history of BVs on the web, I've come across values that range all over the place, varying by hundreds of dollars per B share. I don't know how to make sense of that.

I'm sure all this is elementary for most here, but that's where I'm at. If anyone can provide, or point me to, an accurate table of historical BRK Book Values per BRK.B share outstanding, going back about 20 years or so, I'd very much appreciate it.

Alternatively, an historical table of IV per BRK.B share would more directly serve the purpose. However that would still require a formula for determining IV on an ongoing basis.

Thanks in advance.
Tom
