Dexter Shoe: His Worst Deal

In 1993, Buffett bought a shoe company called Dexter Shoe. He thought it was a strong business that would stay ahead of others for a long time. He was wrong. Cheap shoes from other countries flooded in, and within a few years Dexter could not keep up. The business became worth almost nothing - basically zero. On its own, that would just be an ordinary mistake.

But Dexter is the deal every investor should sit and think about, because of how he paid for it. Buffett did not pay with cash. He paid with shares of his own company, Berkshire Hathaway. (Remember, a share is one small piece of a company - so he handed over small pieces of Berkshire.) And here is the sting: Berkshire kept growing bigger and richer for decades. So the shares he gave away kept becoming worth more and more - in someone else's hands. The real cost of his mistake did not stop when Dexter died. It kept growing, year after year. Buffett has called it the worst deal he ever made, and says it cost him billions - all because he paid with a thing that keeps getting more valuable.

This study reads two lessons stacked on top of each other. First: even careful thinking about a business can be flatly wrong if a rival changes the game. Second, and deeper: how you pay can turn a bad deal into a disaster. Paying with a thing that grows, to buy a thing that dies, is a mistake that keeps punishing you.

Break the Dexter mistake into its two separate losses, because most people only see the first one.

The first loss: the business. Buffett believed Dexter had a lasting edge over rivals in shoemaking. It did not last. A wave of cheap imported shoes washed the edge away within a few years. This is the loss everyone sees - a business bought for real money that became worth nothing. It hurts, but it has a limit: you can only lose what you put in.

The second loss: what he paid with. Buffett paid for Dexter with Berkshire shares. Each of those shares was a small piece of everything Berkshire owned - a bundle of wonderful businesses that would keep growing for decades. When Dexter failed, the cash value of that shoe business was gone. But the shares he had handed to the sellers did not vanish - they kept climbing along with Berkshire. So the sellers walked away with something worth many times more than Dexter, forever. That means the true cost of the deal was not the price of Dexter in 1993. It was whatever those Berkshire shares grew into over the next decades - a cost that keeps growing long after the mistake was made.

Look at the growing gap between the two lines. If Buffett had paid with cash, the loss would have stopped at Dexter's price and stayed flat forever - that is the flat line. Because he paid with shares of a growing company, the true cost followed the rising line, getting bigger every single year as those shares became worth more. The business was dead within a few years; the cost went on ballooning for decades. That is the special, growing cruelty of paying for things with something that keeps rising in value.

illustrative Suppose a company pays for another business with shares worth ₹100 crore today, and the business it bought fails within five years. If the payment had been cash, the loss is ₹100 crore - full stop, chapter closed. But the shares handed over were pieces of a company that keeps growing at, say, 15% every year. Ten years later, those same shares are worth about ₹405 crore. Twenty years later, about ₹1,637 crore. The buyer did not really "lose ₹100 crore." It lost whatever those shares grew into. By paying with something that roughly quadruples every ten years, it turned a ₹100 crore mistake into a giant one - only because of how it paid.

The big lesson Buffett draws from Dexter: use your shares to buy something only when you are getting back at least as much worth as you are giving up - and be extra careful, because your own shares are most tempting to spend exactly when the price is high, which is often when they are actually cheap compared to what they will grow into. Handing over shares of a business you believe will grow, to buy a business that then fails, is the most expensive way to be wrong.

Looking back it seems obvious; it wasn't. Buffett's study of Dexter's edge was careful, and still wrong, because a change in the world's manufacturing - not a mistake in his thinking - killed the edge. The lesson is not "he was careless." It is that even good analysis can be beaten by a change nobody controls. An edge is a bet on the future, not a certainty.

Paying in shares is not always the error - overpaying is. Using your shares to pay is fine when you get back at least equal worth. Many good deals are done with shares. The mistake grows only when the thing you bought is worth less than the shares you gave up. Do not read Dexter as "never pay with shares." Read it as "paying with something that keeps rising raises the price of being wrong."

The growing cost is a missed gain, not a fresh cash loss. Berkshire did not write a bigger cheque each year. It simply gave up the growth those shares would have earned. That is a real cost, but it is the invisible kind - which is exactly why it is so easy to ignore at the moment of the deal, and why Buffett makes a point of naming it out loud.

The Dexter lesson works for any buyer, and for any person thinking about how they pay - even, on a small scale, the cost of selling a growing asset to buy something that then disappoints. In India, buying companies with shares and swapping promoter shares are common, and the same maths applies: giving away shares of a business that will grow, to buy one that won't, is a mistake that keeps growing. What is special to Buffett is only the size of the growth that made his error so huge. The idea itself - weigh what you give up against what you get, and remember that paying with a rising thing makes a bad buy worse every year - travels everywhere.

• Read how a deal is paid, not just the price. Deals paid in shares carry a hidden, growing cost if the thing bought disappoints.
• Insist on equal worth in a share deal. Paying in shares is only sound when you get back at least what you give up.
• Beware shares spent when they are high. Bosses are most tempted to pay in shares when the price is dear - which is exactly when giving them away costs the most in the long run.
• Respect that an edge can break from outside. Careful analysis can still be undone by a change in trade, technology, or rules - leave room for that.
• Name the missed gain. Ask what the thing you spent would have grown into - that, not the sticker price, is the real cost of a mistake.
