Almost halfway home in our 29-part series examining all of Warren Buffett's letters to Berkshire Hathaway shareholders. With this post, we're moving into the 1990s, yay. To be precise, we'll be looking at Buffett's letter covering the year 1990. Let's see what the oracle has to say:

For I believe the first time in our series, Berkshire Hathaway did not grow by double-digit percentages, although it had grown so large this isn't completely surprising:

...some strengthening in stock prices late in the year enabled us to close 1990 with net worth up by $362 million, or 7.3%. Over the last 26 years (that is, since present management took over) our per-share book value has grown from $19.46 to $4,612.06, or at a rate of 23.2% compounded annually.

Our growth rate was lackluster in 1990 because our four major common stock holdings, in aggregate, showed little change in market value. Last year I told you that though these companies - Capital Cities/ABC, Coca-Cola, GEICO, and Washington Post - had fine businesses and superb managements, widespread recognition of these attributes had pushed the stock prices of the four to lofty levels. The market prices of the two media companies have since fallen significantly - for good reasons relating to evolutionary industry developments that I will discuss later - and the price of Coca-Cola stock has increased significantly for what I also believe are good reasons.

Buffett offers some predictably humble words about his success at managing Berkshire Hathaway, comparing his position to that of a child volunteering to help a magician do his tricks:

My own role in operations may best be illustrated by a small tale concerning my granddaughter, Emily, and her fourth birthday party last fall. Attending were other children, adoring relatives, and Beemer the Clown, a local entertainer who includes magic tricks in his act.

Beginning these, Beemer asked Emily to help him by waving a "magic wand" over "the box of wonders." Green handkerchiefs went into the box, Emily waved the wand, and Beemer removed blue ones. Loose handkerchiefs went in and, upon a magisterial wave by Emily, emerged knotted. After four such transformations, each more amazing than its predecessor, Emily was unable to contain herself. Her face aglow, she exulted: "Gee, I'm really good at this."

As Berkshire's stock holdings increased over the year, the company was gaining much more worth on paper than it was reporting in its actual earnings (much in the way that you can hold a stock for years and watch it go up and up but never actually touch the earnings until you sell). Berkshire consistently emphasizes this point, as he feels that Berkshire's worth is often much greater than an earnings number might suggest:

Berkshire's own reported earnings are misleading in a different, but important, way: We have huge investments in companies ("investees") whose earnings far exceed their dividends and in which we record our share of earnings only to the extent of the dividends we receive. The extreme case is Capital Cities/ABC, Inc. Our 17% share of the company's earnings amounted to more than $83 million last year. Yet only about $530,000 ($600,000 of dividends it paid us less some $70,000 of tax) is counted in Berkshire's GAAP earnings. The residual $82 million-plus stayed with Cap Cities as retained earnings, which work for our benefit but go unrecorded on our books.

In discussing the slipping profits of media businesses that Berkshre owned or invested in, Buffett offered this opinion:

The reason media businesses have been so outstanding in the past was not physical growth, but rather the unusual pricing power that most participants wielded. Now, however, advertising dollars are growing slowly. In addition, retailers that do little or no media advertising (though they sometimes use the Postal Service) have gradually taken market share in certain merchandise categories. Most important of all, the number of both print and electronic advertising channels has substantially increased. As a consequence, advertising dollars are more widely dispersed and the pricing power of ad vendors has diminished. These circumstances materially reduce the intrinsic value of our major media investments and also the value of our operating unit, Buffalo News - though all remain fine businesses.

A fun passage that illustrates Buffett's investing philosophy:

We will be buying businesses - or small parts of businesses, called stocks - year in, year out as long as I live (and longer, if Berkshire's directors attend the seances I have scheduled). Given these intentions, declining prices for businesses benefit us, and rising prices hurt us.

The most common cause of low prices is pessimism - some times pervasive, some times specific to a company or industry. We want to do business in such an environment, not because we like pessimism but because we like the prices it produces. It's optimism that is the enemy of the rational buyer.

None of this means, however, that a business or stock is an intelligent purchase simply because it is unpopular; a contrarian approach is just as foolish as a follow-the-crowd strategy. What's required is thinking rather than polling. Unfortunately, Bertrand Russell's observation about life in general applies with unusual force in the financial world: "Most men would rather die than think. Many do."

Finally, Buffett on succession planning:

I feel strongly that the fate of our businesses and their managers should not depend on my health - which, it should be added, is excellent - and I have planned accordingly. Neither my estate plan nor that of my wife is designed to preserve the family fortune; instead, both are aimed at preserving the character of Berkshire and returning the fortune to society.

Were I to die tomorrow, you could be sure of three things: (1) None of my stock would have to be sold; (2) Both a controlling shareholder and a manager with philosophies similar to mine would follow me; and (3) Berkshire's earnings would increase by $1 million annually, since Charlie would immediately sell our corporate jet, The Indefensible (ignoring my wish that it be buried with me).
