Warren Buffett on Compounding

True, our country in its infancy sometimes borrowed abroad to supplement our own savings. But, concurrently, we needed many Americans to consistently save and then needed those savers or other Americans to wisely deploy the capital thus made available. If America had consumed all that it produced, the country would have been spinning its wheels. The American process has not always been pretty – our country has forever had many scoundrels and promoters who seek to take advantage of those who mistakenly trust them with their savings. But even with such malfeasance – which remains in full force today – and also much deployment of capital that eventually floundered because of brutal competition or disruptive innovation, the savings of Americans has delivered a quantity and quality of output beyond the dreams of any colonist. From a base of only four million people – and despite a brutal internal war early on, pitting one American against another – America changed the world in the blink of a celestial eye. * * * * * * * * * * * * In a very minor way, Berkshire shareholders have participated in the American miracle by foregoing dividends, thereby electing to reinvest rather than consume. Originally, this reinvestment was tiny, almost meaningless, but over time, it mushroomed, reflecting the mixture of a sustained culture of savings, combined with the magic of long-term compounding. Berkshire’s activities now impact all corners of our country. And we are not finished.

The casino now resides in many homes and daily tempts the occupants. One fact of financial life should never be forgotten. Wall Street – to use the term in its figurative sense – would like its customers to make money, but what truly causes its denizens’ juices to flow is feverish activity. At such times, whatever foolishness can be marketed will be vigorously marketed – not by everyone but always by someone. Occasionally, the scene turns ugly. The politicians then become enraged; the most flagrant perpetrators of misdeeds slip away, rich and unpunished; and your friend next door becomes bewildered, poorer and sometimes vengeful. Money, he learns, has trumped morality. One investment rule at Berkshire has not and will not change: Never risk permanent loss of capital. Thanks to the American tailwind and the power of compound interest, the arena in which we operate has been – and will be – rewarding if you make a couple of good decisions during a lifetime and avoid serious mistakes. * * * * * * * * * * * * I believe Berkshire can handle financial disasters of a magnitude beyond any heretofore experienced. This ability is one we will not relinquish. When economic upsets occur, as they will, Berkshire’s goal will be to function as an asset to the country – just as it was in a very minor way in 2008-9 – and to help extinguish the financial fire rather than to be among the many companies that, inadvertently or otherwise, ignited the conflagration.

And then came a stroke of good luck: National Indemnity became available in 1967, and we shifted our resources toward insurance and other non-textile operations. Thus began our journey to 2023, a bumpy road involving a combination of continuous savings by our owners (that is, by their retaining earnings), the power of compounding, our avoidance of major mistakes and – most important of all – the American Tailwind. America would have done fine without Berkshire. The reverse is not true. Berkshire now enjoys major ownership in an unmatched collection of huge and diversified businesses. Let’s first look at the 5,000 or so publicly-held companies that trade daily on NASDAQ, the NYSE and related venues. Within this group is housed the members of the S&P 500 Index, an elite collection of large and well-known American companies. In aggregate, the 500 earned $1.8 trillion in 2021. I don’t yet have the final results for 2022. Using, therefore, the 2021 figures, only 128 of the 500 (including Berkshire itself) earned $3 billion or more. Indeed, 23 lost money.

Coupling reinvestment of earnings with the power of compounding worked its magic, and shareholders prospered. Berkshire’s owners, it should be noted, were not the only beneficiary of that course correction. Their “silent partner,” the U.S. Treasury, proceeded to collect many tens of billions of dollars from the company in income tax payments. Remember the $100 daily? Now, Berkshire pays roughly $9 million daily to the Treasury.

His book began, therefore, with a confession: “These studies are the record of a failure – the failure of facts to sustain a preconceived theory.” Luckily for investors, that failure led Smith to think more deeply about how stocks should be evaluated. For the crux of Smith’s insight, I will quote an early reviewer of his book, none other than John Maynard Keynes: “I have kept until last what is perhaps Mr. Smith’s most important, and is certainly his most novel, point. Well-managed industrial companies do not, as a rule, distribute to the shareholders the whole of their earned profits. In good years, if not in all years, they retain a part of their profits and put them back into the business. Thus there is an element of compound interest (Keynes’ italics) operating in favour of a sound industrial investment. Over a period of years, the real value of the property of a sound industrial is increasing at compound interest, quite apart from the dividends paid out to the shareholders.” And with that sprinkling of holy water, Smith was no longer obscure. It’s difficult to understand why retained earnings were unappreciated by investors before Smith’s book was published. After all, it was no secret that mind-boggling wealth had earlier been amassed by such titans as Carnegie, Rockefeller and Ford, all of whom had retained a huge portion of their business earnings to fund growth and produce ever-greater profits.

Throughout America, also, there had long been small-time capitalists who became rich following the same playbook. Nevertheless, when business ownership was sliced into small pieces – “stocks” – buyers in the pre-Smith years usually thought of their shares as a short-term gamble on market movements. Even at their best, stocks were considered speculations. Gentlemen preferred bonds. Though investors were slow to wise up, the math of retaining and reinvesting earnings is now well understood. Today, school children learn what Keynes termed “novel”: combining savings with compound interest works wonders. * * * * * * * * * * * * At Berkshire, Charlie and I have long focused on using retained earnings advantageously. Sometimes this job has been easy – at other times, more than difficult, particularly when we began working with huge and ever- growing sums of money. In our deployment of the funds we retain, we first seek to invest in the many and diverse businesses we already own. During the past decade, Berkshire’s depreciation charges have aggregated $65 billion whereas the company’s internal investments in property, plant and equipment have totaled $121 billion. Reinvestment in productive operational assets will forever remain our top priority. In addition, we constantly seek to buy new businesses that meet three criteria. First, they must earn good returns on the net tangible capital required in their operation. Second, they must be run by able and honest managers.

Forecasting interest rates has never been our game, and Charlie and I have no idea what rates will average over the next year, or ten or thirty years. Our perhaps jaundiced view is that the pundits who opine on these subjects reveal, by that very behavior, far more about themselves than they reveal about the future. What we can say is that if something close to current rates should prevail over the coming decades and if corporate tax rates also remain near the low level businesses now enjoy, it is almost certain that equities will over time perform far better than long-term, fixed-rate debt instruments. That rosy prediction comes with a warning: Anything can happen to stock prices tomorrow. Occasionally, there will be major drops in the market, perhaps of 50% magnitude or even greater. But the combination of The American Tailwind, about which I wrote last year, and the compounding wonders described by Mr. Smith, will make equities the much better long-term choice for the individual who does not use borrowed money and who can control his or her emotions. Others? Beware! The Road Ahead Three decades ago, my Midwestern friend, Joe Rosenfield, then in his 80s, received an irritating letter from his local newspaper. In blunt words, the paper asked for biographical data it planned to use in Joe’s obituary. Joe didn’t respond. So? A month later, he got a second letter from the paper, this one labeled “URGENT.” Charlie and I long ago entered the urgent zone.

Our level of equity capital is a different story: Berkshire’s $349 billion is unmatched in corporate America. By retaining all earnings for a very long time, and allowing compound interest to work its magic, we have amassed funds that have enabled us to purchase and develop the valuable groves earlier described. Had we instead followed a 100% payout policy, we would still be working with the $22 million with which we began fiscal 1965. Beyond using debt and equity, Berkshire has benefitted in a major way from two less-common sources of corporate funding. The larger is the float I have described. So far, those funds, though they are recorded as a huge net liability on our balance sheet, have been of more utility to us than an equivalent amount of equity. That’s because they have usually been accompanied by underwriting earnings. In effect, we have been paid in most years for holding and using other people’s money. As I have often done before, I will emphasize that this happy outcome is far from a sure thing: Mistakes in assessing insurance risks can be huge and can take many years to surface. (Think asbestos.) A major catastrophe that will dwarf hurricanes Katrina and Michael will occur – perhaps tomorrow, perhaps many decades from now. “The Big One” may come from a traditional source, such as a hurricane or earthquake, or it may be a total surprise involving, say, a cyber attack having disastrous consequences beyond anything insurers now contemplate.

BERKSHIRE HATHAWAY INC. To the Shareholders of Berkshire Hathaway Inc.: Berkshire’s gain in net worth during 2017 was $65.3 billion, which increased the per-share book value of both our Class A and Class B stock by 23%. Over the last 53 years (that is, since present management took over), per- share book value has grown from $19 to $211,750, a rate of 19.1% compounded annually.* The format of that opening paragraph has been standard for 30 years. But 2017 was far from standard: A large portion of our gain did not come from anything we accomplished at Berkshire. The $65 billion gain is nonetheless real – rest assured of that. But only $36 billion came from Berkshire’s operations. The remaining $29 billion was delivered to us in December when Congress rewrote the U.S. Tax Code. (Details of Berkshire’s tax-related gain appear on page K-32 and pages K-89 – K-90.) After stating those fiscal facts, I would prefer to turn immediately to discussing Berkshire’s operations. But, in still another interruption, I must first tell you about a new accounting rule – a generally accepted accounting principle (GAAP) – that in future quarterly and annual reports will severely distort Berkshire’s net income figures and very often mislead commentators and investors. The new rule says that the net change in unrealized investment gains and losses in stocks we hold must be included in all net income figures we report to you.

For the last 53 years, the company has built value by reinvesting its earnings and letting compound interest work its magic. Year by year, we have moved forward. Yet Berkshire shares have suffered four truly major dips. Here are the gory details: Period High Low Percentage Decrease March 1973-January 1975 93 38 (59.1%) 10/2/87-10/27/87 4,250 2,675 (37.1%) 6/19/98-3/10/2000 80,900 41,300 (48.9%) 9/19/08-3/5/09 147,000 72,400 (50.7%) This table offers the strongest argument I can muster against ever using borrowed money to own stocks. There is simply no telling how far stocks can fall in a short period. Even if your borrowings are small and your positions aren’t immediately threatened by the plunging market, your mind may well become rattled by scary headlines and breathless commentary. And an unsettled mind will not make good decisions.

BERKSHIRE HATHAWAY INC. To the Shareholders of Berkshire Hathaway Inc.: Berkshire’s gain in net worth during 2016 was $27.5 billion, which increased the per-share book value of both our Class A and Class B stock by 10.7%. Over the last 52 years (that is, since present management took over), per-share book value has grown from $19 to $172,108, a rate of 19% compounded annually.* During the first half of those years, Berkshire’s net worth was roughly equal to the number that really counts: the intrinsic value of the business. The similarity of the two figures existed then because most of our resources were deployed in marketable securities that were regularly revalued to their quoted prices (less the tax that would be incurred if they were to be sold). In Wall Street parlance, our balance sheet was then in very large part “marked to market.” By the early 1990s, however, our focus was changing to the outright ownership of businesses, a shift that materially diminished the relevance of balance sheet figures. That disconnect occurred because the accounting rules (commonly referred to as “GAAP”) that apply to companies we control differ in important ways from those used to value marketable securities. Specifically, the accounting for businesses we own requires that the carrying value of “losers” be written down when their failures become apparent. “Winners,” conversely, are never revalued upwards.

4% Footnote: Under my agreement with Protégé Partners, the names of these funds-of-funds have never been publicly disclosed. I, however, see their annual audits. The compounded annual increase to date for the index fund is 7.1%, which is a return that could easily prove typical for the stock market over time. That’s an important fact: A particularly weak nine years for the market over the lifetime of this bet would have probably helped the relative performance of the hedge funds, because many hold large “short” positions. Conversely, nine years of exceptionally high returns from stocks would have provided a tailwind for index funds. Instead we operated in what I would call a “neutral” environment. In it, the five funds-of-funds delivered, through 2016, an average of only 2.2%, compounded annually. That means $1 million invested in those funds would have gained $220,000. The index fund would meanwhile have gained $854,000.

BERKSHIRE HATHAWAY INC. To the Shareholders of Berkshire Hathaway Inc.: Berkshire’s gain in net worth during 2015 was $15.4 billion, which increased the per-share book value of both our Class A and Class B stock by 6.4%. Over the last 51 years (that is, since present management took over), per-share book value has grown from $19 to $155,501, a rate of 19.2% compounded annually.* During the first half of those years, Berkshire’s net worth was roughly equal to the number that really counts: the intrinsic value of the business. The similarity of the two figures existed then because most of our resources were deployed in marketable securities that were regularly revalued to their quoted prices (less the tax that would be incurred if they were to be sold). In Wall Street parlance, our balance sheet was then in very large part “marked to market.” By the early 1990s, however, our focus had changed to the outright ownership of businesses, a shift that diminished the relevance of balance-sheet figures. That disconnect occurred because the accounting rules that apply to controlled companies are materially different from those used in valuing marketable securities. The carrying value of the “losers” we own is written down, but “winners” are never revalued upwards. We’ve had experience with both outcomes: I’ve made some dumb purchases, and the amount I paid for the economic goodwill of those companies was later written off, a move that reduced Berkshire’s book value.

America’s population is growing about .8% per year (.5% from births minus deaths and .3% from net migration). Thus 2% of overall growth produces about 1.2% of per capita growth. That may not sound impressive. But in a single generation of, say, 25 years, that rate of growth leads to a gain of 34.4% in real GDP per capita. (Compounding’s effects produce the excess over the percentage that would result by simply multiplying 25 x 1.2%.) In turn, that 34.4% gain will produce a staggering $19,000 increase in real GDP per capita for the next generation. Were that to be distributed equally, the gain would be $76,000 annually for a family of four. Today’s politicians need not shed tears for tomorrow’s children. Indeed, most of today’s children are doing well. All families in my upper middle-class neighborhood regularly enjoy a living standard better than that achieved by John D. Rockefeller Sr. at the time of my birth. His unparalleled fortune couldn’t buy what we now take for granted, whether the field is – to name just a few – transportation, entertainment, communication or medical services. Rockefeller certainly had power and fame; he could not, however, live as well as my neighbors now do. Though the pie to be shared by the next generation will be far larger than today’s, how it will be divided will remain fiercely contentious.

If the wind didn’t blow and the earth didn’t shake, we made large profits. But a mega-catastrophe would produce red ink. In order to be conservative then in stating our business earnings, we consistently assumed that underwriting would break even over time and ignored any of its gains or losses in our annual calculation of the second factor of value. Today, our insurance results are likely to be more stable than was the case a decade or two ago because we have deemphasized catastrophe coverages and greatly expanded our bread-and-butter lines of business. Last year, our underwriting income contributed $1,118 per share to the $12,304 per share of earnings referenced in the second paragraph of this section. Over the past decade, annual underwriting income has averaged $1,434 per share, and we anticipate being profitable in most years. You should recognize, however, that underwriting in any given year could well be unprofitable, perhaps substantially so. Since 1970, our per-share investments have increased at a rate of 18.9% compounded annually, and our earnings (including the underwriting results in both the initial and terminal year) have grown at a 23.7% clip. It is no coincidence that the price of Berkshire stock over the ensuing 45 years has increased at a rate very similar to that of our two measures of value. Charlie and I like to see gains in both sectors, but our main goal is to build operating earnings.

A note to readers: Fifty years ago, today’s management took charge at Berkshire. For this Golden Anniversary, Warren Buffett and Charlie Munger each wrote his views of what has happened at Berkshire during the past 50 years and what each expects during the next 50. Neither changed a word of his commentary after reading what the other had written. Warren’s thoughts begin on page 24 and Charlie’s on page 39. Shareholders, particularly new ones, may find it useful to read those letters before reading the report on 2014, which begins below. BERKSHIRE HATHAWAY INC. To the Shareholders of Berkshire Hathaway Inc.: Berkshire’s gain in net worth during 2014 was $18.3 billion, which increased the per-share book value of both our Class A and Class B stock by 8.3%. Over the last 50 years (that is, since present management took over), per-share book value has grown from $19 to $146,186, a rate of 19.4% compounded annually.* During our tenure, we have consistently compared the yearly performance of the S&P 500 to the change in Berkshire’s per-share book value. We’ve done that because book value has been a crude, but useful, tracking device for the number that really counts: intrinsic business value. In our early decades, the relationship between book value and intrinsic value was much closer than it is now. That was true because Berkshire’s assets were then largely securities whose values were continuously restated to reflect their current market prices.

Since 1970, our per-share investments have increased at a rate of 19% compounded annually, and our earnings figure has grown at a 20.6% clip. It is no coincidence that the price of Berkshire stock over the ensuing 44 years has increased at a rate very similar to that of our two measures of value. Charlie and I like to see gains in both sectors, but our main focus is to build operating earnings. That’s why we were pleased to exchange our Phillips 66 and Graham Holdings stock for operating businesses last year and to contract with Procter and Gamble to acquire Duracell by means of a similar exchange set to close in 2015. * * * * * * * * * * * * Now, let’s examine the four major sectors of our operations. Each has vastly different balance sheet and income characteristics from the others. So we’ll present them as four separate businesses, which is how Charlie and I view them (though there are important and enduring advantages to having them all under one roof). Our goal is to provide you with the information we would wish to have if our positions were reversed, with you being the reporting manager and we the absentee shareholders. (But don’t get any ideas!) Insurance Let’s look first at insurance, Berkshire’s core operation. That industry has been the engine that has propelled our expansion since 1967, when we acquired National Indemnity and its sister company, National Fire & Marine, for $8.6 million.

BERKSHIRE HATHAWAY INC. To the Shareholders of Berkshire Hathaway Inc.: Berkshire’s gain in net worth during 2013 was $34.2 billion. That gain was after our deducting $1.8 billion of charges – meaningless economically, as I will explain later – that arose from our purchase of the minority interests in Marmon and Iscar. After those charges, the per-share book value of both our Class A and Class B stock increased by 18.2%. Over the last 49 years (that is, since present management took over), book value has grown from $19 to $134,973, a rate of 19.7% compounded annually.* On the facing page, we show our long-standing performance measurement: The yearly change in Berkshire’s per-share book value versus the market performance of the S&P 500. What counts, of course, is per- share intrinsic value. But that’s a subjective figure, and book value is useful as a rough tracking indicator. (An extended discussion of intrinsic value is included in our Owner-Related Business Principles on pages 103 - 108. Those principles have been included in our reports for 30 years, and we urge new and prospective shareholders to read them.) As I’ve long told you, Berkshire’s intrinsic value far exceeds its book value. Moreover, the difference has widened considerably in recent years. That’s why our 2012 decision to authorize the repurchase of shares at 120% of book value made sense.

Intrinsic Business Value As much as Charlie and I talk about intrinsic business value, we cannot tell you precisely what that number is for Berkshire shares (nor, in fact, for any other stock). In our 2010 annual report, however, we laid out the three elements – one of them qualitative – that we believe are the keys to a sensible estimate of Berkshire’s intrinsic value. That discussion is reproduced in full on pages 109 - 110. Here is an update of the two quantitative factors: In 2013 our per-share investments increased 13.6% to $129,253 and our pre-tax earnings from businesses other than insurance and investments increased 12.8% to $9,116 per share. Since 1970, our per-share investments have increased at a rate of 19.3% compounded annually, and our earnings figure has grown at a 20.6% clip. It is no coincidence that the price of Berkshire stock over the 43-year period has increased at a rate very similar to that of our two measures of value. Charlie and I like to see gains in both sectors, but we will most strongly focus on building operating earnings. * * * * * * * * * * * * Now, let’s examine the four major sectors of our operations. Each has vastly different balance sheet and income characteristics from the others. So we’ll present them as four separate businesses, which is how Charlie and I view them (though there are important and enduring advantages to having them all under one roof).

BERKSHIRE HATHAWAY INC. To the Shareholders of Berkshire Hathaway Inc.: In 2012, Berkshire achieved a total gain for its shareholders of $24.1 billion. We used $1.3 billion of that to repurchase our stock, which left us with an increase in net worth of $22.8 billion for the year. The per-share book value of both our Class A and Class B stock increased by 14.4%. Over the last 48 years (that is, since present management took over), book value has grown from $19 to $114,214, a rate of 19.7% compounded annually.* A number of good things happened at Berkshire last year, but let’s first get the bad news out of the way. Š When the partnership I ran took control of Berkshire in 1965, I could never have dreamed that a year in which we had a gain of $24.1 billion would be subpar, in terms of the comparison we present on the facing page. But subpar it was. For the ninth time in 48 years, Berkshire’s percentage increase in book value was less than the S&P’s percentage gain (a calculation that includes dividends as well as price appreciation). In eight of those nine years, it should be noted, the S&P had a gain of 15% or more. We do better when the wind is in our face. To date, we’ve never had a five-year period of underperformance, having managed 43 times to surpass the S&P over such a stretch. (The record is on page 103.) But the S&P has now had gains in each of the last four years, outpacing us over that period.

Here is an update of the two quantitative factors: In 2012 our per-share investments increased 15.7% to $113,786, and our per-share pre-tax earnings from businesses other than insurance and investments also increased 15.7% to $8,085. Since 1970, our per-share investments have increased at a rate of 19.4% compounded annually, and our per-share earnings figure has grown at a 20.8% clip. It is no coincidence that the price of Berkshire stock over the 42-year period has increased at a rate very similar to that of our two measures of value. Charlie and I like to see gains in both areas, but our strong emphasis will always be on building operating earnings. * * * * * * * * * * * * Now, let’s examine the four major sectors of our operations. Each has vastly different balance sheet and income characteristics from the others. Lumping them together therefore impedes analysis. So we’ll present them as four separate businesses, which is how Charlie and I view them.

BERKSHIRE HATHAWAY INC. To the Shareholders of Berkshire Hathaway Inc.: The per-share book value of both our Class A and Class B stock increased by 4.6% in 2011. Over the last 47 years (that is, since present management took over), book value has grown from $19 to $99,860, a rate of 19.8% compounded annually.* Charlie Munger, Berkshire’s Vice Chairman and my partner, and I feel good about the company’s progress during 2011. Here are the highlights: • The primary job of a Board of Directors is to see that the right people are running the business and to be sure that the next generation of leaders is identified and ready to take over tomorrow. I have been on 19 corporate boards, and Berkshire’s directors are at the top of the list in the time and diligence they have devoted to succession planning. What’s more, their efforts have paid off. As 2011 started, Todd Combs joined us as an investment manager, and shortly after yearend Ted Weschler came aboard. Both of these men have outstanding investment skills and a deep commitment to Berkshire. Each will be handling a few billion dollars in 2012, but they have the brains, judgment and character to manage our entire portfolio when Charlie and I are no longer running Berkshire. Your Board is equally enthusiastic about my successor as CEO, an individual to whom they have had a great deal of exposure and whose managerial and human qualities they admire. (We have two superb back-up candidates as well.)

Exxon Mobil will probably have delivered trillions of dollars in dividends to its owners and will also hold assets worth many more trillions (and, remember, you get 16 Exxons). The 170,000 tons of gold will be unchanged in size and still incapable of producing anything. You can fondle the cube, but it will not respond. Admittedly, when people a century from now are fearful, it’s likely many will still rush to gold. I’m confident, however, that the $9.6 trillion current valuation of pile A will compound over the century at a rate far inferior to that achieved by pile B. • Our first two categories enjoy maximum popularity at peaks of fear: Terror over economic collapse drives individuals to currency-based assets, most particularly U.S. obligations, and fear of currency collapse fosters movement to sterile assets such as gold. We heard “cash is king” in late 2008, just when cash should have been deployed rather than held. Similarly, we heard “cash is trash” in the early 1980s just when fixed-dollar investments were at their most attractive level in memory. On those occasions, investors who required a supportive crowd paid dearly for that comfort. My own preference – and you knew this was coming – is our third category: investment in productive assets, whether businesses, farms, or real estate. Ideally, these assets should have the ability in inflationary times to deliver output that will retain its purchasing-power value while requiring a minimum of new capital investment.

Farms, real estate, and many businesses such as Coca-Cola, IBM and our own See’s Candy meet that double-barreled test. Certain other companies – think of our regulated utilities, for example – fail it because inflation places heavy capital requirements on them. To earn more, their owners must invest more. Even so, these investments will remain superior to nonproductive or currency-based assets. Whether the currency a century from now is based on gold, seashells, shark teeth, or a piece of paper (as today), people will be willing to exchange a couple of minutes of their daily labor for a Coca-Cola or some See’s peanut brittle. In the future the U.S. population will move more goods, consume more food, and require more living space than it does now. People will forever exchange what they produce for what others produce. Our country’s businesses will continue to efficiently deliver goods and services wanted by our citizens. Metaphorically, these commercial “cows” will live for centuries and give ever greater quantities of “milk” to boot. Their value will be determined not by the medium of exchange but rather by their capacity to deliver milk. Proceeds from the sale of the milk will compound for the owners of the cows, just as they did during the 20th century when the Dow increased from 66 to 11,497 (and paid loads of dividends as well). Berkshire’s goal will be to increase its ownership of first-class businesses.

BERKSHIRE HATHAWAY INC. To the Shareholders of Berkshire Hathaway Inc.: The per-share book value of both our Class A and Class B stock increased by 13% in 2010. Over the last 46 years (that is, since present management took over), book value has grown from $19 to $95,453, a rate of 20.2% compounded annually.* The highlight of 2010 was our acquisition of Burlington Northern Santa Fe, a purchase that’s working out even better than I expected. It now appears that owning this railroad will increase Berkshire’s “normal” earning power by nearly 40% pre-tax and by well over 30% after-tax. Making this purchase increased our share count by 6% and used $22 billion of cash. Since we’ve quickly replenished the cash, the economics of this transaction have turned out very well. A “normal year,” of course, is not something that either Charlie Munger, Vice Chairman of Berkshire and my partner, or I can define with anything like precision. But for the purpose of estimating our current earning power, we are envisioning a year free of a mega-catastrophe in insurance and possessing a general business climate somewhat better than that of 2010 but weaker than that of 2005 or 2006. Using these assumptions, and several others that I will explain in the “Investment” section, I can estimate that the normal earning power of the assets we currently own is about $17 billion pre-tax and $12 billion after-tax, excluding any capital gains or losses.

BERKSHIRE HATHAWAY INC. To the Shareholders of Berkshire Hathaway Inc.: Our gain in net worth during 2009 was $21.8 billion, which increased the per-share book value of both our Class A and Class B stock by 19.8%. Over the last 45 years (that is, since present management took over) book value has grown from $19 to $84,487, a rate of 20.3% compounded annually.* Berkshire’s recent acquisition of Burlington Northern Santa Fe (BNSF) has added at least 65,000 shareholders to the 500,000 or so already on our books. It’s important to Charlie Munger, my long-time partner, and me that all of our owners understand Berkshire’s operations, goals, limitations and culture. In each annual report, consequently, we restate the economic principles that guide us. This year these principles appear on pages 89-94 and I urge all of you – but particularly our new shareholders – to read them. Berkshire has adhered to these principles for decades and will continue to do so long after I’m gone. In this letter we will also review some of the basics of our business, hoping to provide both a freshman orientation session for our BNSF newcomers and a refresher course for Berkshire veterans. How We Measure Ourselves Our metrics for evaluating our managerial performance are displayed on the facing page. From the start, Charlie and I have believed in having a rational and unbending standard for measuring what we have – or have not – accomplished.

In aggregate, our businesses are worth considerably more than the values at which they are carried on our books. In our all-important insurance business, moreover, the difference is huge. Even so, Charlie and I believe that our book value – understated though it is – supplies the most useful tracking device for changes in intrinsic value. By this measurement, as the opening paragraph of this letter states, our book value since the start of fiscal 1965 has grown at a rate of 20.3% compounded annually. *All per-share figures used in this report apply to Berkshire’s A shares. Figures for the B shares are 1/1500 th of those shown for A.

We should note that had we instead chosen market prices as our yardstick, Berkshire’s results would look better, showing a gain since the start of fiscal 1965 of 22% compounded annually. Surprisingly, this modest difference in annual compounding rate leads to an 801,516% market-value gain for the entire 45-year period compared to the book-value gain of 434,057% (shown on page 2). Our market gain is better because in 1965 Berkshire shares sold at an appropriate discount to the book value of its underearning textile assets, whereas today Berkshire shares regularly sell at a premium to the accounting values of its first-class businesses. Summed up, the table on page 2 conveys three messages, two positive and one hugely negative. First, we have never had any five-year period beginning with 1965-69 and ending with 2005-09 – and there have been 41 of these – during which our gain in book value did not exceed the S&P’s gain. Second, though we have lagged the S&P in some years that were positive for the market, we have consistently done better than the S&P in the eleven years during which it delivered negative results. In other words, our defense has been better than our offense, and that’s likely to continue. The big minus is that our performance advantage has shrunk dramatically as our size has grown, an unpleasant trend that is certain to continue.

BERKSHIRE HATHAWAY INC. To the Shareholders of Berkshire Hathaway Inc.: Our decrease in net worth during 2008 was $11.5 billion, which reduced the per-share book value of both our Class A and Class B stock by 9.6%. Over the last 44 years (that is, since present management took over) book value has grown from $19 to $70,530, a rate of 20.3% compounded annually.* The table on the preceding page, recording both the 44-year performance of Berkshire’s book value and the S&P 500 index, shows that 2008 was the worst year for each. The period was devastating as well for corporate and municipal bonds, real estate and commodities. By yearend, investors of all stripes were bloodied and confused, much as if they were small birds that had strayed into a badminton game. As the year progressed, a series of life-threatening problems within many of the world’s great financial institutions was unveiled. This led to a dysfunctional credit market that in important respects soon turned non-functional. The watchword throughout the country became the creed I saw on restaurant walls when I was young: “In God we trust; all others pay cash.” By the fourth quarter, the credit crisis, coupled with tumbling home and stock prices, had produced a paralyzing fear that engulfed the country. A freefall in business activity ensued, accelerating at a pace that I have never before witnessed. The U.S. – and much of the world – became trapped in a vicious negative-feedback cycle.

But let’s use that figure and also assume that the most likely decline – should one occur – is 50%. Under these assumptions, the mathematical expectation of loss on our contract would be $5 million ($1 billion X 1% X 50%). But if we had received our theoretical premium of $2.5 million up front, we would have only had to invest it at 0.7% compounded annually to cover this loss expectancy. Everything earned above that would have been profit. Would you like to borrow money for 100 years at a 0.7% rate? Let’s look at my example from a worst-case standpoint. Remember that 99% of the time we would pay nothing if my assumptions are correct. But even in the worst case among the remaining 1% of possibilities – that is, one assuming a total loss of $1 billion – our borrowing cost would come to only 6.2%. Clearly, either my assumptions are crazy or the formula is inappropriate.

BERKSHIRE HATHAWAY INC. To the Shareholders of Berkshire Hathaway Inc.: Our gain in net worth during 2007 was $12.3 billion, which increased the per-share book value of both our Class A and Class B stock by 11%. Over the last 43 years (that is, since present management took over) book value has grown from $19 to $78,008, a rate of 21.1% compounded annually.* Overall, our 76 operating businesses did well last year. The few that had problems were primarily those linked to housing, among them our brick, carpet and real estate brokerage operations. Their setbacks are minor and temporary. Our competitive position in these businesses remains strong, and we have first- class CEOs who run them right, in good times or bad. Some major financial institutions have, however, experienced staggering problems because they engaged in the “weakened lending practices” I described in last year’s letter. John Stumpf, CEO of Wells Fargo, aptly dissected the recent behavior of many lenders: “It is interesting that the industry has invented new ways to lose money when the old ways seemed to work just fine.” You may recall a 2003 Silicon Valley bumper sticker that implored, “Please, God, Just One More Bubble.” Unfortunately, this wish was promptly granted, as just about all Americans came to believe that house prices would forever rise.

The average holdings of bonds and cash for all pension funds is about 28%, and on these assets returns can be expected to be no more than 5%. Higher yields, of course, are obtainable but they carry with them a risk of commensurate (or greater) loss. This means that the remaining 72% of assets – which are mostly in equities, either held directly or through vehicles such as hedge funds or private-equity investments – must earn 9.2% in order for the fund overall to achieve the postulated 8%. And that return must be delivered after all fees, which are now far higher than they have ever been. How realistic is this expectation? Let’s revisit some data I mentioned two years ago: During the 20th Century, the Dow advanced from 66 to 11,497. This gain, though it appears huge, shrinks to 5.3% when compounded annually. An investor who owned the Dow throughout the century would also have received generous dividends for much of the period, but only about 2% or so in the final years. It was a wonderful century. Think now about this century. For investors to merely match that 5.3% market-value gain, the Dow – recently below 13,000 – would need to close at about 2,000,000 on December 31, 2099. We are now eight years into this century, and we have racked up less than 2,000 of the 1,988,000 Dow points the market needed to travel in this hundred years to equal the 5.3% of the last.

BERKSHIRE HATHAWAY INC. To the Shareholders of Berkshire Hathaway Inc.: Our gain in net worth during 2006 was $16.9 billion, which increased the per-share book value of both our Class A and Class B stock by 18.4%. Over the last 42 years (that is, since present management took over) book value has grown from $19 to $70,281, a rate of 21.4% compounded annually.* We believe that $16.9 billion is a record for a one-year gain in net worth – more than has ever been booked by any American business, leaving aside boosts that have occurred because of mergers (e.g., AOL’s purchase of Time Warner). Of course, Exxon Mobil and other companies earn far more than Berkshire, but their earnings largely go to dividends and/or repurchases, rather than to building net worth. All that said, a confession about our 2006 gain is in order. Our most important business, insurance, benefited from a large dose of luck: Mother Nature, bless her heart, went on vacation. After hammering us with hurricanes in 2004 and 2005 – storms that caused us to lose a bundle on super-cat insurance – she just vanished. Last year, the red ink from this activity turned black – very black. In addition, the great majority of our 73 businesses did outstandingly well in 2006. Let me focus for a moment on one of our largest operations, GEICO. What management accomplished there was simply extraordinary. As I’ve told you before, Tony Nicely, GEICO’s CEO, went to work at the company 45 years ago, two months after turning 18.

The first is the amount of investments (including cash and cash-equivalents) that we own on a per-share basis. Arriving at this figure, we exclude investments held in our finance operation because these are largely offset by borrowings. Here’s the record since present management acquired control of Berkshire: Year Per-Share Investments* 1965 ..................................................................... $ 4 1975 ..................................................................... 159 1985 ..................................................................... 2,407 1995 ..................................................................... 21,817 2006 ..................................................................... $80,636 Compound Growth Rate 1965-2006.................... 27.5% Compound Growth Rate 1995-2006.................... 12.6% *Net of minority interests In our early years we put most of our retained earnings and insurance float into investments in marketable securities. Because of this emphasis, and because the securities we purchased generally did well, our growth rate in investments was for a long time quite high. Over the years, however, we have focused more and more on the acquisition of operating businesses. Using our funds for these purchases has both slowed our growth in investments and accelerated our gains in pre-tax earnings from non-insurance businesses, the second yardstick we use.looked:

Year Pre-Tax Earnings Per Share* 1965 ..................................................................... $ 4 1975 ..................................................................... 4 1985 ..................................................................... 52 1995 ..................................................................... 175 2006 ..................................................................... $3,625 Compound Growth Rate 1965-2006 .................... 17.9% Compound Growth Rate 1995-2006 .................... 31.7% *Excluding purchase-accounting adjustments and net of minority interests Last year we had a good increase in non-insurance earnings – 38%. Large gains from here on in, though, will come only if we are able to make major, and sensible, acquisitions. That will not be easy. We do, however, have one advantage: More and more, Berkshire has become “the buyer of choice” for business owners and managers. Initially, we were viewed that way only in the U.S. (and more often than not by private companies). We’ve long wanted, nonetheless, to extend Berkshire’s appeal beyond U.S. borders. And last year, our globe-trotting finally got underway. Acquisitions We began 2006 by completing the three acquisitions pending at yearend 2005, spending about $6 billion for PacifiCorp, Business Wire and Applied Underwriters. All are performing very well.

Already the prediction I made last year about one fall-out from our spending binge has come true: The “investment income” account of our country – positive in every previous year since 1915 – turned negative in 2006. Foreigners now earn more on their U.S. investments than we do on our investments abroad. In effect, we’ve used up our bank account and turned to our credit card. And, like everyone who gets in hock, the U.S. will now experience “reverse compounding” as we pay ever-increasing amounts of interest on interest. I want to emphasize that even though our course is unwise, Americans will live better ten or twenty years from now than they do today. Per-capita wealth will increase. But our citizens will also be forced every year to ship a significant portion of their current production abroad merely to service the cost of our huge debtor position.over-consumption

BERKSHIRE HATHAWAY INC. To the Shareholders of Berkshire Hathaway Inc.: Our gain in net worth during 2005 was $5.6 billion, which increased the per-share book value of both our Class A and Class B stock by 6.4%. Over the last 41 years (that is, since present management took over) book value has grown from $19 to $59,377, a rate of 21.5% compounded annually.* Berkshire had a decent year in 2005. We initiated five acquisitions (two of which have yet to close) and most of our operating subsidiaries prospered. Even our insurance business in its entirety did well, though Hurricane Katrina inflicted record losses on both Berkshire and the industry. We estimate our loss from Katrina at $2.5 billion – and her ugly sisters, Rita and Wilma, cost us an additional $.9 billion. Credit GEICO – and its brilliant CEO, Tony Nicely – for our stellar insurance results in a disaster- ridden year. One statistic stands out: In just two years, GEICO improved its productivity by 32%. Remarkably, employment fell by 4% even as policy count grew by 26% – and more gains are in store. When we drive unit costs down in such a dramatic manner, we can offer ever-greater value to our customers. The payoff: Last year, GEICO gained market-share, earned commendable profits and strengthened its brand. If you have a new son or grandson in 2006, name him Tony. * * * * * * * * * * * * My goal in writing this report is to give you the information you need to estimate Berkshire’s intrinsic value.

Year Per-Share Investments* 1965 ..................................................................... $ 4 1975 ..................................................................... 159 1985 ..................................................................... 2,407 1995 ..................................................................... 21,817 2005 ..................................................................... $74,129 Compound Growth Rate 1965-2005.................... 28.0% Compound Growth Rate 1995-2005.................... 13.0% *Net of minority interests In addition to these marketable securities, which with minor exceptions are held in our insurance companies, we own a wide variety of non-insurance businesses.

12 in the 20th century, and that amounts to a gain of 5.3% compounded annually. (Investors would also have received dividends, of course.) To achieve an equal rate of gain in the 21st century, the Dow will have to rise by December 31, 2099 to – brace yourself – precisely 2,011,011.23. But I’m willing to settle for 2,000,000; six years into this century, the Dow has gained not at all. Debt and Risk As we consolidate MidAmerican, our new balance sheet may suggest that Berkshire has expanded its tolerance for borrowing. But that’s not so. Except for token amounts, we shun debt, turning to it for only three purposes: 1) We occasionally use repos as a part of certain short-term investing strategies that incorporate ownership of U.S. government (or agency) securities. Purchases of this kind are highly opportunistic and involve only the most liquid of securities. A few years ago, we entered into several interesting transactions that have since been unwound or are running off. The offsetting debt has likewise been cut substantially and before long may be gone.

BERKSHIRE HATHAWAY INC. To the Shareholders of Berkshire Hathaway Inc.: Our gain in net worth during 2004 was $8.3 billion, which increased the per-share book value of both our Class A and Class B stock by 10.5%. Over the last 40 years (that is, since present management took over) book value has grown from $19 to $55,824, a rate of 21.9% compounded annually.* It’s per-share intrinsic value that counts, however, not book value. Here, the news is good: Between 1964 and 2004, Berkshire morphed from a struggling northern textile business whose intrinsic value was less than book into a diversified enterprise worth far more than book. Our 40-year gain in intrinsic value has therefore somewhat exceeded our 21.9% gain in book. (For an explanation of intrinsic value and the economic principles that guide Charlie Munger, my partner and Berkshire’s vice-chairman, and me in running Berkshire, please read our Owner’s Manual, beginning on page 73.) Despite their shortcomings, yearly calculations of book value are useful at Berkshire as a slightly understated gauge for measuring the long-term rate of increase in our intrinsic value. The calculations are less relevant, however, than they once were in rating any single year’s performance versus the S&P 500 index (a comparison we display on the facing page).

To the Shareholders of Berkshire Hathaway Inc.: Our gain in net worth during 1997 was $8.0 billion, which increased the per-share book value of both our Class A and Class B stock by 34.1%. Over the last 33 years (that is, since present management took over) per-share book value has grown from $19 to $25,488, a rate of 24.1% compounded annually.(1) 1. All figures used in this report apply to Berkshire's A shares, the successor to the only stock that the company had outstanding before 1996. The B shares have an economic interest equal to 1/30th that of the A.

To the Shareholders of Berkshire Hathaway Inc.: Our gain in net worth during 1996 was $6.2 billion, or 36.1%. Per- share book value, however, grew by less, 31.8%, because the number of Berkshire shares increased: We issued stock in acquiring FlightSafety International and also sold new Class B shares.* Over the last 32 years (that is, since present management took over) per-share book value has grown from $19 to $19,011, or at a rate of 23.8% compounded annually.

To the Shareholders of Berkshire Hathaway Inc.: Our gain in net worth during 1995 was $5.3 billion, or 45.0%. Per-share book value grew by a little less, 43.1%, because we paid stock for two acquisitions, increasing our shares outstanding by 1.3%. Over the last 31 years (that is, since present management took over) per-share book value has grown from $19 to $14,426, or at a rate of 23.6% compounded annually.

I discussed the USAir investment at length in last year's report. The company's results improved in 1995, but it still faces significant problems. On the plus side for us is the fact that our preferred is structurally well-designed: For example, though we have not been paid dividends since June 1994, the amounts owed us are compounding at 5% over the prime rate. On the minus side is the fact that we are dealing with a weak credit.

To the Shareholders of Berkshire Hathaway Inc.: Our gain in net worth during 1994 was $1.45 billion or 13.9%. Over the last 30 years (that is, since present management took over) our per-share book value has grown from $19 to $10,083, or at a rate of 23% compounded annually. Charlie Munger, Berkshire's Vice Chairman and my partner, and I make few predictions. One we will confidently offer, however, is that the future performance of Berkshire won't come close to matching the performance of the past.

It has become fashionable at public companies to describe almost every compensation plan as aligning the interests of management with those of shareholders. In our book, alignment means being a partner in both directions, not just on the upside. Many "alignment" plans flunk this basic test, being artful forms of "heads I win, tails you lose." A common form of misalignment occurs in the typical stock option arrangement, which does not periodically increase the option price to compensate for the fact that retained earnings are building up the wealth of the company. Indeed, the combination of a ten-year option, a low dividend payout, and compound interest can provide lush gains to a manager who has done no more than tread water in his job. A cynic might even note that when payments to owners are held down, the profit to the option-holding manager increases. I have yet to see this vital point spelled out in a proxy statement asking shareholders to approve an option plan.

To the Shareholders of Berkshire Hathaway Inc.: Our per-share book value increased 14.3% during 1993. Over the last 29 years (that is, since present management took over) book value has grown from $19 to $8,854, or at a rate of 23.3% compounded annually. During the year, Berkshire's net worth increased by $1.5 billion, a figure affected by two negative and two positive non- operating items. For the sake of completeness, I'll explain them here. If you aren't thrilled by accounting, however, feel free to fast-forward through this discussion:

What this little tale tells us is that tax-paying investors will realize a far, far greater sum from a single investment that compounds internally at a given rate than from a succession of investments compounding at the same rate. But I suspect many Berkshire shareholders figured that out long ago. At this point in the report we've customarily provided you with a table showing the annual "combined ratio" of the insurance industry for the preceding decade. This ratio compares total insurance costs (losses incurred plus expenses) to revenue from premiums. For many years, the ratio has been above 100, a level indicating an underwriting loss. That is, the industry has taken in less money each year from its policyholders than it has had to pay for operating expenses and for loss events that occurred during the year.

To the Shareholders of Berkshire Hathaway Inc.: Our per-share book value increased 20.3% during 1992. Over the last 28 years (that is, since present management took over) book value has grown from $19 to $7,745, or at a rate of 23.6% compounded annually. During the year, Berkshire's net worth increased by $1.52 billion. More than 98% of this gain came from earnings and appreciation of portfolio securities, with the remainder coming from the issuance of new stock. These shares were issued as a result of our calling our convertible debentures for redemption on January 4, 1993, and of some holders electing to receive common shares rather than the cash that was their alternative. Most holders of the debentures who converted into common waited until January to do it, but a few made the move in December and therefore received shares in 1992. To sum up what happened to the $476 million of bonds we had outstanding: $25 million were converted into shares before yearend; $46 million were converted in January; and $405 million were redeemed for cash. The conversions were made at $11,719 per share, so altogether we issued 6,106 shares.

To the Shareholders of Berkshire Hathaway Inc.: Our gain in net worth during 1991 was $2.1 billion, or 39.6%. Over the last 27 years (that is, since present management took over) our per-share book value has grown from $19 to $6,437, or at a rate of 23.7% compounded annually. The size of our equity capital - which now totals $7.4 billion - makes it certain that we cannot maintain our past rate of gain or, for that matter, come close to doing so. As Berkshire grows, the universe of opportunities that can significantly influence the company's performance constantly shrinks. When we were working with capital of $20 million, an idea or business producing $1 million of profit added five percentage points to our return for the year. Now we need a $370 million idea (i.e., one contributing over $550 million of pre-tax profit) to achieve the same result. And there are many more ways to make $1 million than to make $370 million.

BERKSHIRE HATHAWAY INC. To the Shareholders of Berkshire Hathaway Inc.: Last year we made a prediction: "A reduction [in Berkshire's net worth] is almost certain in at least one of the next three years." During much of 1990's second half, we were on the road to quickly proving that forecast accurate. But 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. Overall, yearend 1990 prices of our "permanent four," though far from enticing, were a bit more appealing than they were a year earlier.

To the Shareholders of Berkshire Hathaway Inc.: Our gain in net worth during 1989 was $1.515 billion, or 44.4%. Over the last 25 years (that is, since present management took over) our per-share book value has grown from $19.46 to $4,296.01, or at a rate of 23.8% compounded annually. What counts, however, is intrinsic value - the figure indicating what all of our constituent businesses are rationally worth. With perfect foresight, this number can be calculated by taking all future cash flows of a business - in and out - and discounting them at prevailing interest rates. So valued, all businesses, from manufacturers of buggy whips to operators of cellular phones, become economic equals.

A second form of zero-coupon U. S. Treasury issue, also benign and useful, surfaced in the last decade. One problem with a normal bond is that even though it pays a given interest rate - say 10% - the holder cannot be assured that a compounded 10% return will be realized. For that rate to materialize, each semi- annual coupon must be reinvested at 10% as it is received. If current interest rates are, say, only 6% or 7% when these coupons come due, the holder will be unable to compound his money over the life of the bond at the advertised rate. For pension funds or other investors with long-term liabilities, "reinvestment risk" of this type can be a serious problem. Savings Bonds might have solved it, except that they are issued only to individuals and are unavailable in large denominations. What big buyers needed was huge quantities of "Savings Bond Equivalents."

Under this new standard, a business earning, say, $100 million pre-tax and having debt on which $90 million of interest must be paid currently, might use a zero-coupon or PIK issue to incur another $60 million of annual interest that would accrue and compound but not come due for some years. The rate on these issues would typically be very high, which means that the situation in year 2 might be $90 million cash interest plus $69 million accrued interest, and so on as the compounding proceeds. Such high-rate reborrowing schemes, which a few years ago were appropriately confined to the waterfront, soon became models of modern finance at virtually all major investment banking houses.

Because we are delighted by our experience with Jim, HBI and the NYSE, I said as much in ads that have been run in a series placed by the NYSE. Normally I shun testimonials, but I was pleased in this instance to publicly compliment the Exchange. Last summer we sold the corporate jet that we purchased for $850,000 three years ago and bought another used jet for $6.7 million. Those of you who recall the mathematics of the multiplying bacteria on page 5 will understandably panic: If our net worth continues to increase at current rates, and the cost of replacing planes also continues to rise at the now-established rate of 100% compounded annually, it will not be long before Berkshire's entire net worth is consumed by its jet.

Borsheim's normally is closed on Sunday, but we will open for shareholders and their guests from noon to 6 p.m. on Sunday, April 29th. Ike likes to put on a show, and you can rely on him to produce something very special for our shareholders. In this letter we've had a lot to say about rates of compounding. If you can bear having your own rate turn negative for a day - not a pretty thought, I admit - visit Ike on the 29th.

To the Shareholders of Berkshire Hathaway Inc.: Our gain in net worth during 1988 was $569 million, or 20.0%. Over the last 24 years (that is, since present management took over), our per-share book value has grown from $19.46 to $2,974.52, or at a rate of 23.0% compounded annually. We've emphasized in past reports that what counts, however, is intrinsic business value - the figure, necessarily an estimate, indicating what all of our constituent businesses are worth. By our calculations, Berkshire's intrinsic business value significantly exceeds its book value. Over the 24 years, business value has grown somewhat faster than book value; in 1988, however, book value grew the faster, by a bit.

To the Shareholders of Berkshire Hathaway Inc.: Our gain in net worth during 1987 was $464 million, or 19.5%. Over the last 23 years (that is, since present management took over), our per-share book value has grown from $19.46 to $2,477.47, or at a rate of 23.1% compounded annually. What counts, of course, is the rate of gain in per-share business value, not book value. In many cases, a corporation's book value and business value are almost totally unrelated. For example, just before they went bankrupt, LTV and Baldwin-United published yearend audits showing their book values to be $652 million and $397 million, respectively. Conversely, Belridge Oil was sold to Shell in 1979 for $3.6 billion although its book value was only $177 million.

To the Shareholders of Berkshire Hathaway Inc.: Our gain in net worth during 1986 was $492.5 million, or 26.1%. Over the last 22 years (that is, since present management took over), our per-share book value has grown from $19.46 to $2,073.06, or 23.3% compounded annually. Both the numerator and denominator are important in the per-share book value calculation: during the 22-year period our corporate net worth has increased 10,600% while shares outstanding have increased less than 1%.

Our gain in net worth during the year was $613.6 million, or 48.2%. It is fitting that the visit of Halley's Comet coincided with this percentage gain: neither will be seen again in my lifetime. Our gain in per-share book value over the last twenty- one years (that is, since present management took over) has been from $19.46 to $1643.71, or 23.2% compounded annually, another percentage that will not be repeated.

You might think that institutions, with their large staffs of highly-paid and experienced investment professionals, would be a force for stability and reason in financial markets. They are not: stocks heavily owned and constantly monitored by institutions have often been among the most inappropriately valued. Ben Graham told a story 40 years ago that illustrates why investment professionals behave as they do: An oil prospector, moving to his heavenly reward, was met by St. Peter with bad news. 'You're qualified for residence', said St. Peter, 'but, as you can see, the compound reserved for oil men is packed. There's no way to squeeze you in.' After thinking a moment, the prospector asked if he might say just four words to the present occupants. That seemed harmless to St. Peter, so the prospector cupped his hands and yelled, 'Oil discovered in hell.' Immediately the gate to the compound opened and all of the oil men marched out to head for the nether regions. Impressed, St. Peter invited the prospector to move in and make himself comfortable. The prospector paused. 'No,' he said, 'I think I'll go along with the rest of the boys. There might be some truth to that rumor after all.'

When returns on capital are ordinary, an earn-more-by- putting-up-more record is no great managerial achievement. You can get the same result personally while operating from your rocking chair. just quadruple the capital you commit to a savings account and you will quadruple your earnings. You would hardly expect hosannas for that particular accomplishment. Yet, retirement announcements regularly sing the praises of CEOs who have, say, quadrupled earnings of their widget company during their reign - with no one examining whether this gain was attributable simply to many years of retained earnings and the workings of compound interest.

An example will illustrate the inequities possible under such circumstances. Let's suppose that you had a $100,000 savings account earning 8% interest and 'managed' by a trustee who could decide each year what portion of the interest you were to be paid in cash. Interest not paid out would be 'retained earnings' added to the savings account to compound. And let's suppose that your trustee, in his superior wisdom, set the 'pay- out ratio' at one-quarter of the annual earnings.

During the 19-year tenure of present management, book value has grown from $19.46 per share to $975.83, or 22.6% compounded annually. Considering our present size, nothing close to this rate of return can be sustained. Those who believe otherwise should pursue a career in sales, but avoid one in mathematics. We report our progress in terms of book value because in our case (though not, by any means, in all cases) it is a conservative but reasonably adequate proxy for growth in intrinsic business value - the measurement that really counts. Book value's virtue as a score-keeping measure is that it is easy to calculate and doesn't involve the subjective (but important) judgments employed in calculation of intrinsic business value. It is important to understand, however, that the two terms - book value and intrinsic business value - have very different meanings.

Our gain in net worth during 1982, valuing equities held by our insurance subsidiaries at market value (less capital gain taxes payable if unrealized gains were actually realized) amounted to $208 million. On a beginning net worth base of $519 million, the percentage gain was 40%. During the 18-year tenure of present management, book value has grown from $19.46 per share to $737.43 per share, or 22.0% compounded annually. You can be certain that this percentage will diminish in the future. Geometric progressions eventually forge their own anchors.

On a GAAP basis, during the present management's term of seventeen years, book value has increased from $19.46 per share to $526.02 per share, or 21.1% compounded annually. This rate of return number is highly likely to drift downward in future years. We hope, however, that it can be maintained significantly above the rate of return achieved by the average large American corporation.

In the sixteen years since present management assumed responsibility for Berkshire, book value per share with insurance-held equities valued at market has increased from $19.46 to $400.80, or 20.5% compounded annually. (You've done better: the value of the mineral content in the human body compounded at 22% annually during the past decade.) It is encouraging, moreover, to realize that our record was achieved despite many mistakes. The list is too painful and lengthy to detail here. But it clearly shows that a reasonably competitive corporate batting average can be achieved in spite of a lot of managerial strikeouts.

The book value per share of Berkshire Hathaway on September 30, 1964 (the fiscal yearend prior to the time that your present management assumed responsibility) was $19.46 per share. At yearend 1979, book value with equity holdings carried at market value was $335.85 per share. The gain in book value comes to 20.5% compounded annually. This figure, of course, is far higher than any average of our yearly operating earnings calculations, and reflects the importance of capital appreciation of insurance equity investments in determining the overall results for our shareholders. It probably also is fair to say that the quoted book value in 1964 somewhat overstated the intrinsic value of the enterprise, since the assets owned at that time on either a going concern basis or a liquidating value basis were not worth 100 cents on the dollar. (The liabilities were solid, however.)

With that preamble it can be stated that, with or without restated figures, 1978 was a good year. Operating earnings, exclusive of capital gains, at 19.4% of beginning shareholders' investment were within a fraction of our 1972 record. While we believe it is improper to include capital gains or losses in evaluating the performance of a single year, they are an important component of the longer term record. Because of such gains, Berkshire's long-term growth in equity per share has been greater than would be indicated by compounding the returns from operating earnings that we have reported annually.

For example, over the last three years - generally a bonanza period for the insurance industry, our largest profit producer - Berkshire's per share net worth virtually has doubled, thereby compounding at about 25% annually through a combination of good operating earnings and fairly substantial capital gains. Neither this 25% equity gain from all sources nor the 19.4% equity gain from operating earnings in 1978 is sustainable. The insurance cycle has turned downward in 1979, and it is almost certain that operating earnings measured by return on equity will fall this year. However, operating earnings measured in dollars are likely to increase on the much larger shareholders' equity now employed in the business.

Most companies define 'record' earnings as a new high in earnings per share. Since businesses customarily add from year to year to their equity base, we find nothing particularly noteworthy in a management performance combining, say, a 10% increase in equity capital and a 5% increase in earnings per share. After all, even a totally dormant savings account will produce steadily rising interest earnings each year because of compounding.
