Hello, my name is Jeff Colbett, and I'm from Olathe, Kansas.
I got started in investing in 1999, right before the big tech bubble.
And unfortunately, I learned buy and hold and don't fret about market price fluctuations
before I learned the importance of valuing a business and applying a margin of safety.
So, as Charlie said, I got my feet wet with huge failure right away.
Right in the club.
Thank you. I don't feel so bad now.
So that leads to my question.
I've read all the Berkshire reports and all the reading I can do about you two.
And I thank you for these wonderful meetings.
But it seems like it boils down to some simple things,
valuing a business and applying a margin of safety.
So my question is, what do you recommend for an approach
to getting better and better at valuing companies?
That's a very, very good question.
And in my own case, I started out without knowing anything about valuing companies.
And Ben Graham taught me a way to value a certain type of company
that would prove successful, except the universe of those companies dried up.
But nevertheless, it was almost a guarantee against failure.
But it was not a guarantee that these things would continue to be available.
Charlie taught me a lot about the value of a durable competitive advantage
and a really first-class business.
But over time, I've learned more about various types of businesses.
But you'd be amazed how many businesses I don't feel that I understand well.
The biggest thing is not how big your circle of competence is,
but knowing where the perimeter is.
You don't have to be an expert on 90% of the businesses
or 80% or 70 or 50.
But you do have to know something about the ones
that you actually put your money into.
And if that's a very small part of the universe,
that still is not a killer.
And I think if you think about what you would pay for a McDonald's stand,
what you think you would pay for,
you know, think about the businesses in your own hometown,
it's a lot of things.
You know, which would you like to buy into?
Which do you think you could understand their economics?
Which do you think will be around 10 or 20 years from now?
Which do you think it would be very tough to compete with?
Just keep asking yourself questions about businesses.
Talk about it with other people about them.
You will extend your knowledge over time.
And always remember that margin of safety.
And I think you basically have the right attitude
because you do, you recognize your limitations.
And that's enormously important in this business.
You will find things to do.
Six or seven years ago, maybe not that long,
yeah, six or seven years ago,
when I was looking at Korean stocks, for example,
I never had any idea that Korean stocks
would be something that I would be buying.
But I looked over there,
and I could see that there were a number of businesses
that met the margin of safety test.
And there I diversified
because I didn't know that much about any specific one.
But I knew that a package of 20
was going to work out very well,
even if a crook might run one of them
and a couple of them might run into competition
I didn't anticipate, because they were so cheap.
And that was sort of the old Graham approach.
You will find opportunities from time to time.
And the beauty of it is
you don't have to find very many of them.
Charlie.
Well, obviously, if you want to get good at something
which is competitive,
you have to think about it a lot and learn a lot
and practice doing it a lot.
And the way the world is constructed in this field,
you have to keep learning,
because the world keeps changing
and your competitors keep learning.
So you just have to get up each morning
and try and go to bed that night a little wiser
than you were when you got up.
If you keep doing that for a long time
and accumulate some experience, good and bad,
as you try and master what you're trying to do,
people who do that almost never fail utterly.
They may have a bad period
when luck goes against them or something,
but very few people have ever failed with that.
If you have the right temperament,
you may rise slowly, but you're sure to rise.
Charlie, did you take any business courses in school?
None.
I took accounting.
And when did you start valuing businesses
and how did you go about it?
When I was a little boy.
I can remember I would come down to the Omaha Club
and there was an old gentleman
who hit the Omaha Club about 10.30 every morning.
He obviously did almost no work
and yet was quite prosperous.
He became your ideal.
Well, but he made me very curious as a little boy.
I said to my father,
How in the hell does he do that?
And he said,
Charlie, he's in a business
where he enjoys practically no competition.
He gathers up and renders dead horses.
Well, that was an example of avoiding competition
by one strategy.
And if you keep asking questions like that of reality,
starting at a young age, you gradually learn.
And Warren, you were doing the same thing.
Well, yeah, thankfully he extrapolated.
He went beyond his original insight there.
I noticed it was rather interesting.
If you take the rulers of the businesses
when I was a little boy,
an awful lot of those businesses in Omaha,
a lot of those businesses went broke.
A lot of them sold out
at modest prices under distress.
And some of the people who rose
like Kiewit from small beginnings,
nobody thought of as the great glories
of that early time.
And I think that's kind of the way life is.
It's hard to get anywhere near the top.
And it's hard to hold any position
once you've attained it.
But I think you could predict
that Kiewit was likely to win.
They cared more about doing it right.
They cared more about avoiding trouble.
They put more discipline on themselves.
Well, if you knew the individual well,
you would have bet, right?
What?
If you knew the individual,
Pete himself.
I would not have bet
on any of the people I knew
who were already wealthy.
But I would have bet on Pete Kiewit.
His sister taught me math.
And, no, half Dutch, half German.
This is a tough culture.
You've just heard it, folks.
Half Dutch, half German.
Go out looking for them.
Well, the man that's recommending this
is named Munger.
Anyway, the...
No, I don't think it's that.
But if you're...
I was just automatically doing that.
What was working?
What was failing?
Why was it working?
Why was it failing?
You have that temperament
you are gradually going to learn.
And if you don't have that temperament,
I can't help you.
If you'd followed Pete Kiewit around for 10 years,
you never would have seen him
do anything dumb, right?
Oh, yeah.
So, it's avoiding the dumb thing.
You really don't have to be brilliant.
But, you know, you have to avoid
just the sort of what
almost seem the obvious mistakes.
But I would say that
you're on the right track back there
in terms of having the basic fundamentals,
knowing your limitations,
but still seeking to learn more
about various kinds of businesses.
Charlie, I think when he practiced law,
any client that came in,
Charlie was thinking about that business
as if he owned the place.
And he probably generally felt
he knew more about the place
than the guy that actually owned it
who was his client,
who was the client.
But I remember talking to him,
you know, 50 years ago,
and he would start talking about
caterpillar dealerships in Bakersfield
or something of the sort.
He was incapable of looking at a business
without thinking about
the fundamental economics of it.
How'd that guy do with the caterpillar?
Well, he sold it for a perfectly ridiculous price
to a dumb oil company.
It wasn't worth half what he got for it.
But they had a concept.
They had a concept and a strategy,
and no doubt they had consultants.
Becky?
This question comes from Carson Mitchell
in Aberdeen, South Dakota,
who asks both of you,
what business has had the best return
on capital for Berkshire,
and what business of any on earth
has had the best return on capital?
And he adds, P.S.,
I would have come by rail,
but there are no seats
in the grain rail cars.
There's two ways of looking at it.
If you talk about the capital necessary
to run the business
as opposed to what we might have paid
for the business.
I mean, if we buy a wonderful business,
you could run the Coca-Cola company,
assuming you had the bottling system separate.
You could run it with no capital.
Now, if you buy it for $100 billion,
I mean, you can look at that as your capital
or you can look at the basic capital.
When we look at what's a good business,
we're defining it in terms of the capital
actually needed in the business.
Whether it's a good investment for us
depends on how much we pay for that in the end.
There are a number of businesses
that operate on negative capital.
Carol's with Fortune Magazine.
You know, any of the great magazines
operate with negative capital.
I mean, the subscribers pay in advance.
There are no fixed assets to speak of,
and the receivables are not that much.
The inventory is nothing.
So a magazine business,
my guess is that People Magazine operates
or Sports Illustrated operate
with negative capital,
and particularly People makes a lot of money.
So there are certain businesses.
Well, we had a company called Blue Chip Stamps
where we got the float ahead of time
and operated with
really substantial negative capital.
But there are a lot of great businesses
that need very, very little capital.
Apple doesn't need that much capital.
The best ones, of course,
are the ones that get very large
while needing no capital.
See's is a wonderful business
that needs very little capital,
but we can't get people eating
10 pounds of boxed chocolates every day.
Except here.
We want to.
Generally, the great consumer businesses
need relatively little capital.
The businesses where people pay you in advance,
you know, magazines, of course, being a case,
insurance being a case,
you know, you're using your customers' capital.
And we like those kind of businesses,
but, of course, so does the rest of the world,
so they can become very competitive
in buying them.
We have a business, for example,
that's run wonderfully
by Kathy Barron Tamrez
called Business Wire.
Business Wire does not require a lot of capital.
It has receivables and everything,
but it is a service-type business,
and many of the service-type businesses
and consumer-type businesses
require a little capital.
And when they get to be successful,
you know, they can really be something.
Charlie?
I've got nothing to add,
but at any rate,
the formula never changes.
If you could own one business in the world,
what would it be, Charlie?
I hope I already own it myself.
You know, you and I got in trouble
by addressing such a subject many decades ago.
That's right.
I don't think I'll come back to it.
OK.
Number 13.
You know, if you name some business
that has incredible pricing power,
you're talking about a business
that's a monopoly or a near monopoly.
Sure.
And I don't think it's very smart
for us to sit up here
naming our most admired business
as something that other people
regard as a monopoly.
OK.
We'll move right along.
