The Value of Corporate Culture: The Case of Berkshire Hathaway

You may think of Warren Buffett as a savvy stock picker but his greater accomplishment is in configuring an exceptionally strong corporation.  Since early in his career, Buffett adopted what he calls the double-barreled approach to capital allocation, meaning both stock picking and business buying. He gained prominence primarily as an investor in stocks, championing a contrarian investment philosophy.

Attracting three generations of devoted followers to a school of thought called “value investing,” he doubted the market’s efficiency and deftly exploited it. Buffett bought stocks of good companies at a fair price, assembling a concentrated portfolio of large stakes in a small number of firms. Today, nearly three-fourths of Berkshire Hathaway Inc. (NYSE:BRK.A) (NYSE:BRK.B)’s stock portfolio consists of just seven stocks.

Late in his career, beginning around 2000, Buffett shot more often through the other half of his double-barreled approach: buying 100 percent of companies run by trusted managers given great autonomy. True, Berkshire Hathaway early on bought all the stock of companies such as Buffalo News and See’s Candies. But, through the 1990s, the first barrel dominated, with Berkshire Hathaway Inc. (NYSE:BRK.A) (NYSE:BRK.B) consisting 80 percent stocks and 20 percent owned companies. That mix gradually reversed and recently flipped, making subsidiary ownership the defining characteristic of today’s Berkshire.

Owning primarily subsidiaries rather than merely stocks gives Berkshire Hathaway Inc. (NYSE:BRK.A) (NYSE:BRK.B)’s a different shape compared to its previous character as the holding company of a famed investor. After all, even for a buy-and-hold investor, stocks come and go. Berkshire Hathaway has sold the stocks of many once-fine companies, including Freddie Mac / Federal Home Loan Mortgage Corp (OTCBB:FMCC), McDonald’s Corporation (NYSE:MCD), and The Walt Disney Company (NYSE:DIS). In contrast, aside from a few Berkshire subsidiaries that it acquired from the Buffett Partnership in the 1970s, Berkshire Hathaway has never sold a subsidiary and vows to retain them through thick and thin.

Despite their variety, moreover, Berkshire Hathaway Inc. (NYSE:BRK.A) (NYSE:BRK.B) companies are remarkably similar when it comes to corporate culture, which is the central discovery I document and elaborate in my upcoming book, Berkshire Beyond Buffett: The Enduring Value of Values. When Berkshire Hathaway consisted mostly of the stock portfolio of a famed stock picker, you could expect that, once that investor departed, the portfolio would naturally be unwound and the company dissolved. Now, however, with Berkshire Hathaway made of companies not stocks, its life expectancy stretches out in multiple decades, not mere years. It certainly goes beyond the stock picker who founded it.

With as many as five hundred operating units sprouting out of fifty primary Berkshire Hathaway Inc. (NYSE:BRK.A) (NYSE:BRK.B) subsidiaries engaged in a wide range of manufacturing, retail, services, transportation, and energy businesses, the conglomerate looks more diverse than the rainbow coalition.  But as I probed beneath the surface into the guts of these operations, I found thoroughgoing unity bound together by a discrete set of big values.

Berkshire Hathaway Inc. (NYSE:BRK.A) (NYSE:BRK.B)’s culture offers several advantages. For one, it has a remarkable capacity to absorb a wide variety of different businesses within a single family. That is an awe-inspiring feat when you think about how difficult it is for many companies to merge their cultures, from famous cases such as Time and Warner to more subtle ones such as Gillette and P&G.

More broadly, corporate culture translates into business performance. For example, a company whose management and shareholders embrace a long-term outlook can better weather financial volatility. Companies with reputations for thrift and conservatism are less likely to default and therefore enjoy higher credit ratings and lower borrowing costs; stock prices of such companies tend to be less volatile, attracting investors.

A business known for integrity—treating suppliers, employees, and customers as the business would like to be treated if the positions were reversed—will usually win more interest and cooperation among such groups than rivals who are chiselers. Such a reputation for excellence—in merchandising, manufacturing, services, or other business activities—can manifest in better terms of trade at the outset of relationships and more flexibility to cope with periodic adversity.

Yet it is not always easy to measure or even identify the particular advantage or the process through which intangibles take on economic value.     Corporate culture, a modern concept akin to vague old notions like team spirit, is trickier to define than venerable tools of business analysis, such as return on investment. Soft and capacious, culture results from multiple inputs, which may conflict with one another. My book includes an elaborate illustration of this pervasive phenomenon across all of Berkshire’s subsidiaries.

Business leaders build cultures by promoting or exemplifying given values. Values help decision-making, motivate, attract people who share them, and repel those who don’t. Values are also sticky—they are hard to change and tend to endure. The simpler the values are to convey the more durable they tend to be. The earlier a business leader taps the potential of shared values, the more resilient a corporate culture becomes, offering the leader an enduring legacy.

In the case of Berkshire Hathaway Inc. (NYSE:BRK.A) (NYSE:BRK.B) and its subsidiaries, Buffett along with the founders and successive managers of those subsidiaries illustrate the process in action, which Berkshire Beyond Buffett chronicles. The creation of such a corporate culture is a feat of corporate governance, a scenario in which norms of behavior and expectations are more important than compliance manuals and organizational structures.  People who are entrusted with wide autonomy end up feeling a greater degree of responsibility than they would if they are subjected to rigorous oversight and second-guessing. Despite its huge scale, Berkshire has not faced many serious scandals.
