Post New

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.

Here is mine, from 2000 on, for the A´s. Accurate? I just hope it is.

Thanks for that. I've been wondering whether the 1500 share divisor for B's is sufficiently constant across the years.

Thanks for that. I've been wondering whether the 1500 share divisor for B's is sufficiently constant across the years.

The 1500 number is definitely the ratio of economic interest between the two share classes, since the last split (50:1 during January 2010, at the time the BNSF acquisition closed)
So, if you want to know the historical book value of the historical equivalent of what a current B share owned, use 1500 for all dates.

If you want to know the book value of what a B share actually looked like before the last split, then you have to switch to the old ratio which was 30:1 for dates before that. I can't think of any practical reason you'd want to do that, unless you have some historical B-share share prices you want to make sense of.

PS here is my table of book per share. The earlier figures are approximations, especially prior to around 1995 when I calculated backwards from the table of stated book value growth rate in the AR rather than looking them up individually, and the release dates are placeholders. I got lazy...I don't think more than a couple of significant figures matter 30 years later. The last 25 years are solid.

I keep track of the release date so I can create a table "known book per share" for any date.

Jim: here is my table of book per share.

Thanks for sharing your table, Jim, and for your explanations. I'm still quite mystified by the great variations in BV per B share that turned up in response to my simple web inquiry – "brk book value per b share".

I'm still quite mystified by the great variations in BV per B share that turned up in response to my simple web inquiry – "brk book value per b share".

Well, if it book value per B share you really want, these are the figures so far this millennium. (book per A share divided by 30, then book per A share divided by 1500 after January 2010)
