Warren Buffett’s ‘Moat’

Buffett’s annual letters have been a treat to its readers. It is replete with anecdotes, wit and lines from country music. Perhaps the best is in this line which announces his successors: “I reluctantly discarded the notion of my continuing to manage the portfolio after my death – abandoning my hope to give new meaning to the term “thinking outside the box.”

A truly great business must have an enduring “moat” (a metaphor for the superiorities some companies possess that make life difficult for their competitors) that protects excellent returns on invested capital. The dynamics of capitalism guarantee that competitors will repeatedly assault any business “castle” that is earning high returns. Therefore, a formidable barrier such as a company’s being the low cost producer (GEICO, Costco) or possessing a powerful world-wide brand (Coca-Cola, Gillette,American Express) is essential for sustained success. Business history is filled with “Roman Candles,” companies whose moats proved illusory but were soon crossed.

Our criterion of “enduring” causes us to rule out industrial companies prone to rapid and continuous change. Though capitalism’s “creative destruction” is highly beneficial for society, it precludes investment certainty. A moat that must be continuously rebuilt will eventually be no moat at all.

Additionally, this criterion eliminates the business whose success depends on having a great manager. Of course, a terrific CEO is a huge asset for any enterprise, and at Berkshire we have an abundance of these managers. Their abilities have created billions of dollars of value that would never have materialized,if typical CEO's had been running their businesses.

But if a business requires a superstar to produce great results, the business itself cannot be deemed great. A medical partnership led by your area’s premier brain surgeon may enjoy out sized and growing earnings, but that tells little about its future. The partnership’s moat will go when the surgeon goes. You can count, though, on the moat of the Mayo Clinic to endure, even though you can’t name its CEO.

The worst sort of business is one that grows rapidly, requires significant capital to engender the growth, and then earns little or no money. Think airlines. I should emphasize that we do not measure the progress of our investments by what their market prices do during any given year. Rather, we evaluate their performance by the two methods we apply to the businesses we own. The first test is improvement in earnings, with our making due allowance for industry conditions. The second test, more subjective, is whether their moats have widened during the year.

The CEO’s CEO

Academicians are not normally credited with great managerial skills. But there are a few exceptions and Dr. M Rammohan Rao is one of them.

What Dr. Rao did as Former Directorat IIM Bangalore till a few years ago, didnot get the press it deserved although the institute has been neck-and-neck with IIM Ahmedabad for the number one slot.Dr. Rao’s transformation of the Indian School of Business, popularly known as ISB, has taken the world by surprise.The Financial Times’ ranked ISB 20th among the world’s best business schools in January 2008 even ahead of the prestigious Kellogg School of Management.

What Dr. Rao did during his three year tenure since 2004 shows his leadership skills and more importantly, focusing on what B-Schools should really be doing– solid research. Within two months of joining, Dr. Rao started the Centre of Analytical Finance (CAF) and no prizes for guessing what his specialization is.In a recent message, Dr. Rao said:“While the world accepts the ISB’s status,we silently reinforce our commitment of being the cornerstone for research-oriented learning. Combine that with a strong focus on becoming one of the world’s top ranked business schools, and we’ve defined our role and our challenge for the years ahead.”


Dr. Rao could not have achieved this acclaim without insisting on a good number of permanent faculty, since ISB’s initial model was largely dependent on visiting faculty from world’s top institutions such as Wharton, Kellogg and London Business School. Even today, ISB gets over 100 visiting faculty. Yet, the 25 permanent faculty today seems a great stabilizing factor.

His bigger achievement perhaps is making ISB financially sound. Before Dr. Rao joined, there were doubts about ISB’s viability, since it was designed as a world class institute with whopping investment in infrastructure and near five-star boarding facilities. Reports suggest that with the phenomenal growth in intake of students
