Warren Buffett's 2016 Annual Shareholder Letter - Part 1

- By Holly LaFon

To the Shareholders of Berkshire Hathaway Inc.:

Berkshire (NYSE:BRK.A)(NYSE:BRK.B)'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.

We've experienced both outcomes: As is the case in marriage, business acquisitions often deliver surprises after the "I do's." I've made some dumb purchases, paying far too much for the economic goodwill of companies we acquired. That later led to goodwill write-offs and to consequent reductions in Berkshire's book value. We've also had some winners among the businesses we've purchased - a few of the winners very big - but have not written those up by a penny.

We have no quarrel with the asymmetrical accounting that applies here. But, over time, it necessarily widens the gap between Berkshire's intrinsic value and its book value. Today, the large - and growing - unrecorded gains at our winners produce an intrinsic value for Berkshire's shares that far exceeds their book value. The overage is truly huge in our property/casualty insurance business and significant also in many other operations.

Over time, stock prices gravitate toward intrinsic value. That's what has happened at Berkshire, a fact explaining why the company's 52-year market-price gain - shown on the facing page - materially exceeds its book-value gain.

What We Hope to Accomplish

Charlie Munger (Trades, Portfolio), Berkshire's Vice Chairman and my partner, and I expect Berkshire's normalized earning power per share to increase every year. Actual earnings, of course, will sometimes decline because of periodic weakness in the U.S. economy. In addition, insurance mega-catastrophes or other industry-specific events may occasionally reduce earnings at Berkshire, even when most American businesses are doing well.

It's our job, though, to over time deliver significant growth, bumpy or not. After all, as stewards of your capital, Berkshire directors have opted to retain all earnings. Indeed, in both 2015 and 2016 Berkshire ranked first among American businesses in the dollar volume of earnings retained, in each year reinvesting many billions of dollars more than did the runner-up. Those reinvested dollars must earn their keep.

Some years, the gains in underlying earning power we achieve will be minor; very occasionally, the cash register will ring loud. Charlie and I have no magic plan to add earnings except to dream big and to be prepared mentally and financially to act fast when opportunities present themselves. Every decade or so, dark clouds will fill the economic skies, and they will briefly rain gold. When downpours of that sort occur, it's imperative that we rush outdoors carrying washtubs, not teaspoons. And that we will do.

I earlier described our gradual shift from a company obtaining most of its gains from investment activities to one that grows in value by owning businesses. Launching that transition, we took baby steps - making small acquisitions whose impact on Berkshire's profits was dwarfed by our gains from marketable securities. Despite that cautious approach, I made one particularly egregious error, acquiring Dexter Shoe for $434 million in 1993. Dexter's value promptly went to zero. The story gets worse: I used stock for the purchase, giving the sellers 25,203 shares of Berkshire that at yearend 2016 were worth more than $6 billion.

That wreck was followed by three key happenings - two positive, one negative - that set us firmly on our present course. At the beginning of 1996, we acquired the half of GEICO we didn't already own, a cash transaction that changed our holding from a portfolio investment into a wholly-owned operating business. GEICO, with its almost unlimited potential, quickly became the centerpiece around which we built what I believe is now the world's premier property/casualty business.

Unfortunately, I followed the GEICO purchase by foolishly using Berkshire stock - a boatload of stock - to buy General Reinsurance in late 1998. After some early problems, General Re has become a fine insurance operation that we prize. It was, nevertheless, a terrible mistake on my part to issue 272,200 shares of Berkshire in buying General Re, an act that increased our outstanding shares by a whopping 21.8%. My error caused Berkshire shareholders to give far more than they received (a practice that - despite the Biblical endorsement - is far from blessed when you are buying businesses).

Early in 2000, I atoned for that folly by buying 76% (since grown to 90%) of MidAmerican Energy, a brilliantly-managed utility business that has delivered us many large opportunities to make profitable and socially-useful investments. The MidAmerican cash purchase - I was learning - firmly launched us on our present course of (1) continuing to build our insurance operation; (2) energetically acquiring large and diversified non-insurance businesses and (3) largely making our deals from internally-generated cash. (Today, I would rather prep for a colonoscopy than issue Berkshire shares.)

Our portfolio of bonds and stocks, de-emphasized though it is, has continued in the post-1998 period to grow and to deliver us hefty capital gains, interest, and dividends. Those portfolio earnings have provided us major help in financing the purchase of businesses. Though unconventional, Berkshire's two-pronged approach to capital allocation gives us a real edge.

Here's our financial record since 1999, when the redirection of our business began in earnest. During the 18-year period covered, Berkshire's outstanding shares grew by only 8.3%, with most of the increase occurring when we purchased BNSF. That, I'm happy to say, was one issuance of stock that made good sense.

Our expectation is that investment gains will continue to be substantial - though totally random as to timing - and that these will supply significant funds for business purchases. Concurrently, Berkshire's superb corps of operating CEOs will focus on increasing earnings at the individual businesses they manage, sometimes helping them to grow by making bolt-on acquisitions. By our avoiding the issuance of Berkshire stock, any improvement in earnings will translate into equivalent per-share gains.

* * * * * * * * * * * *

Our efforts to materially increase the normalized earnings of Berkshire will be aided - as they have been throughout our managerial tenure - by America's economic dynamism. One word sums up our country's achievements: miraculous. From a standing start 240 years ago - a span of time less than triple my days on earth - Americans have combined human ingenuity, a market system, a tide of talented and ambitious immigrants, and the rule of law to deliver abundance beyond any dreams of our forefathers.

You need not be an economist to understand how well our system has worked. Just look around you. See the 75 million owner-occupied homes, the bountiful farmland, the 260 million vehicles, the hyper-productive factories, the great medical centers, the talent-filled universities, you name it - they all represent a net gain for Americans from the barren lands, primitive structures and meager output of 1776. Starting from scratch, America has amassed wealth totaling $90 trillion.

It's true, of course, that American owners of homes, autos and other assets have often borrowed heavily to finance their purchases. If an owner defaults, however, his or her asset does not disappear or lose its usefulness. Rather, ownership customarily passes to an American lending institution that then disposes of it to an American buyer. Our nation's wealth remains intact. As Gertrude Stein put it, "Money is always there, but the pockets change."

Above all, it's our market system - an economic traffic cop ably directing capital, brains and labor - that has created America's abundance. This system has also been the primary factor in allocating rewards. Governmental redirection, through federal, state and local taxation, has in addition determined the distribution of a significant portion of the bounty.

America has, for example, decided that those citizens in their productive years should help both the old and the young. Such forms of aid - sometimes enshrined as "entitlements" - are generally thought of as applying to the aged. But don't forget that four million American babies are born each year with an entitlement to a public education. That societal commitment, largely financed at the local level, costs about $150,000 per baby. The annual cost totals more than $600 billion, which is about 31/ 2% of GDP.

However our wealth may be divided, the mind-boggling amounts you see around you belong almost exclusively to Americans. Foreigners, of course, own or have claims on a modest portion of our wealth. Those holdings, however, are of little importance to our national balance sheet: Our citizens own assets abroad that are roughly comparable in value.

Early Americans, we should emphasize, were neither smarter nor more hard working than those people who toiled century after century before them. But those venturesome pioneers crafted a system that unleashed human potential, and their successors built upon it.

This economic creation will deliver increasing wealth to our progeny far into the future. Yes, the build-up of wealth will be interrupted for short periods from time to time. It will not, however, be stopped. I'll repeat what I've both said in the past and expect to say in future years: Babies born in America today are the luckiest crop in history.

* * * * * * * * * * * *

America's economic achievements have led to staggering profits for stockholders. During the 20th century the Dow-Jones Industrials advanced from 66 to 11,497, a 17,320% capital gain that was materially boosted by steadily increasing dividends. The trend continues: By yearend 2016, the index had advanced a further 72%, to 19,763.

American business - and consequently a basket of stocks - is virtually certain to be worth far more in the years ahead. Innovation, productivity gains, entrepreneurial spirit and an abundance of capital will see to that. Ever-present naysayers may prosper by marketing their gloomy forecasts. But heaven help them if they act on the nonsense they peddle.

Many companies, of course, will fall behind, and some will fail. Winnowing of that sort is a product of market dynamism. Moreover, the years ahead will occasionally deliver major market declines - even panics - that will affect virtually all stocks. No one can tell you when these traumas will occur - not me, not Charlie, not economists, not the media. Meg McConnell of the New York Fed aptly described the reality of panics: "We spend a lot of time looking for systemic risk; in truth, however, it tends to find us."

During such scary periods, you should never forget two things: First, widespread fear is your friend as an investor, because it serves up bargain purchases. Second, personal fear is your enemy. It will also be unwarranted. Investors who avoid high and unnecessary costs and simply sit for an extended period with a collection of large, conservatively-financed American businesses will almost certainly do well.

As for Berkshire, our size precludes a brilliant result: Prospective returns fall as assets increase. Nonetheless, Berkshire's collection of good businesses, along with the company's impregnable financial strength and owner-oriented culture, should deliver decent results. We won't be satisfied with less.

In the investment world, discussions about share repurchases often become heated. But I'd suggest that participants in this debate take a deep breath: Assessing the desirability of repurchases isn't that complicated.

From the standpoint of exiting shareholders, repurchases are always a plus. Though the day-to-day impact of these purchases is usually minuscule, it's always better for a seller to have an additional buyer in the market.

For continuing shareholders, however, repurchases only make sense if the shares are bought at a price below intrinsic value. When that rule is followed, the remaining shares experience an immediate gain in intrinsic value. Consider a simple analogy: If there are three equal partners in a business worth $3,000 and one is bought out by the partnership for $900, each of the remaining partners realizes an immediate gain of $50. If the exiting partner is paid $1,100, however, the continuing partners each suffer a loss of $50. The same math applies with corporations and their shareholders. Ergo, the question of whether a repurchase action is value-enhancing or value-destroying for continuing shareholders is entirely purchase-price dependent.

It is puzzling, therefore, that corporate repurchase announcements almost never refer to a price above which repurchases will be eschewed. That certainly wouldn't be the case if a management was buying an outside business. There, price would always factor into a buy-or-pass decision.

When CEOs or boards are buying a small part of their own company, though, they all too often seem oblivious to price. Would they behave similarly if they were managing a private company with just a few owners and were evaluating the wisdom of buying out one of them? Of course not.

It is important to remember that there are two occasions in which repurchases should not take place, even if the company's shares are underpriced. One is when a business both needs all its available money to protect or expand its own operations and is also uncomfortable adding further debt. Here, the internal need for funds should take priority. This exception assumes, of course, that the business has a decent future awaiting it after the needed expenditures are made.

The second exception, less common, materializes when a business acquisition (or some other investment opportunity) offers far greater value than do the undervalued shares of the potential repurchaser. Long ago, Berkshire itself often had to choose between these alternatives. At our present size, the issue is far less likely to arise.

My suggestion: Before even discussing repurchases, a CEO and his or her Board should stand, join hands and in unison declare, "What is smart at one price is stupid at another."

* * * * * * * * * * * *

To recap Berkshire's own repurchase policy: I am authorized to buy large amounts of Berkshire shares at 120% or less of book value because our Board has concluded that purchases at that level clearly bring an instant and material benefit to continuing shareholders. By our estimate, a 120%-of-book price is a significant discount to Berkshire's intrinsic value, a spread that is appropriate because calculations of intrinsic value can't be precise.

The authorization given me does not mean that we will "prop" our stock's price at the 120% ratio. If that level is reached, we will instead attempt to blend a desire to make meaningful purchases at a value-creating price with a related goal of not over-influencing the market.

To date, repurchasing our shares has proved hard to do. That may well be because we have been clear in describing our repurchase policy and thereby have signaled our view that Berkshire's intrinsic value is significantly higher than 120% of book value. If so, that's fine. Charlie and I prefer to see Berkshire shares sell in a fairly narrow range around intrinsic value, neither wishing them to sell at an unwarranted high price - it's no fun having owners who are disappointed with their purchases - nor one too low. Furthermore, our buying out "partners" at a discount is not a particularly gratifying way of making money. Still, market circumstances could create a situation in which repurchases would benefit both continuing and exiting shareholders. If so, we will be ready to act.

One final observation for this section: As the subject of repurchases has come to a boil, some people have come close to calling them un-American - characterizing them as corporate misdeeds that divert funds needed for productive endeavors. That simply isn't the case: Both American corporations and private investors are today awash in funds looking to be sensibly deployed. I'm not aware of any enticing project that in recent years has died for lack of capital. (Call us if you have a candidate.)


Let's now look at Berkshire's various businesses, starting with our most important sector, insurance. The property/casualty ("P/C") branch of that industry has been the engine that has propelled our growth since 1967, the year we acquired National Indemnity and its sister company, National Fire & Marine, for $8.6 million. Today, National Indemnity is the largest property/casualty company in the world as measured by net worth.

One reason we were attracted to the P/C business was its financial characteristics: P/C insurers receive premiums upfront and pay claims later. In extreme cases, such as claims arising from exposure to asbestos, payments can stretch over many decades. This collect-now, pay-later model leaves P/C companies holding large sums - money we call "float" - that will eventually go to others. Meanwhile, insurers get to invest this float for their own benefit. Though individual policies and claims come and go, the amount of float an insurer holds usually remains fairly stable in relation to premium volume. Consequently, as our business grows, so does our float. And how it has grown, as the following table shows:

We recently wrote a huge policy that increased float to more than $100 billion. Beyond that one-time boost, float at GEICO and several of our specialized operations is almost certain to grow at a good clip. National Indemnity's reinsurance division, however, is party to a number of large run-off contracts whose float is certain to drift downward.

We may in time experience a decline in float. If so, the decline will be very gradual - at the outside no more than 3% in any year. The nature of our insurance contracts is such that we can never be subject to immediate or near-term demands for sums that are of significance to our cash resources. This structure is by design and is a key component in the unequaled financial strength of our insurance companies. It will never be compromised.

If our premiums exceed the total of our expenses and eventual losses, our insurance operation registers an underwriting profit that adds to the investment income the float produces. When such a profit is earned, we enjoy the use of free money - and, better yet, get paid for holding it.

Unfortunately, the wish of all insurers to achieve this happy result creates intense competition, so vigorous indeed that it sometimes causes the P/C industry as a whole to operate at a significant underwriting loss. This loss, in effect, is what the industry pays to hold its float. Competitive dynamics almost guarantee that the insurance industry, despite the float income all its companies enjoy, will continue its dismal record of earning subnormal returns on tangible net worth as compared to other American businesses.

This outcome is made more certain by the dramatically lower interest rates that now exist throughout the world. The investment portfolios of almost all P/C companies - though not those of Berkshire - are heavily concentrated in bonds. As these high-yielding legacy investments mature and are replaced by bonds yielding a pittance, earnings from float will steadily fall. For that reason, and others as well, it's a good bet that industry results over the next ten years will fall short of those recorded in the past decade, particularly in the case of companies that specialize in reinsurance.

Nevertheless, I very much like our own prospects. Berkshire's unrivaled financial strength allows us far more flexibility in investing than that generally available to P/C companies. The many alternatives available to us are always an advantage; occasionally, they offer us major opportunities. When others are constrained, our choices expand.

Moreover, our P/C companies have an excellent underwriting record. Berkshire has now operated at an underwriting profit for 14 consecutive years, our pre-tax gain for the period having totaled $28 billion. That record is no accident: Disciplined risk evaluation is the daily focus of all of our insurance managers, who know that while float is valuable, its benefits can be drowned by poor underwriting results. All insurers give that message lip service. At Berkshire it is a religion, Old Testament style.

So how does our float affect intrinsic value? When Berkshire's book value is calculated, the full amount of our float is deducted as a liability, just as if we had to pay it out tomorrow and could not replenish it. But to think of float as a typical liability is a major mistake. It should instead be viewed as a revolving fund. Daily, we pay old claims and related expenses - a huge $27 billion to more than six million claimants in 2016 - and that reduces float. Just as surely, we each day write new business that will soon generate its own claims, adding to float.

If our revolving float is both costless and long-enduring, which I believe it will be, the true value of this liability is dramatically less than the accounting liability. Owing $1 that in effect will never leave the premises - because new business is almost certain to deliver a substitute - is worlds different from owing $1 that will go out the door tomorrow and not be replaced. The two types of liabilities, however, are treated as equals under GAAP.

A partial offset to this overstated liability is a $15.5 billion "goodwill" asset that we incurred in buying our insurance companies and that is included in our book-value figure. In very large part, this goodwill represents the price we paid for the float-generating capabilities of our insurance operations. The cost of the goodwill, however, has no bearing on its true value. For example, if an insurance company sustains large and prolonged underwriting losses, any goodwill asset carried on the books should be deemed valueless, whatever its original cost.

Fortunately, that does not describe Berkshire. Charlie and I believe the true economic value of our insurance goodwill - what we would happily pay for float of similar quality were we to purchase an insurance operation possessing it - to be far in excess of its historic carrying value. Indeed, almost the entire $15.5 billion we carry for goodwill in our insurance business was already on our books in 2000 when float was $28 billion. Yet we have subsequently increased our float by $64 billion, a gain that in no way is reflected in our book value. This unrecorded asset is one reason - a huge reason - why we believe Berkshire's intrinsic business value far exceeds its book value.

* * * * * * * * * * * *

Berkshire's attractive insurance economics exist only because we have some terrific managers running disciplined operations that in most cases possess hard-to-replicate business models. Let me tell you about the major units.

First by float size is the Berkshire Hathaway Reinsurance Group, managed by Ajit Jain. Ajit insures risks that no one else has the desire or the capital to take on. His operation combines capacity, speed, decisiveness and, most important, brains in a manner unique in the insurance business. Yet he never exposes Berkshire to risks that are inappropriate in relation to our resources.

Indeed, Berkshire is far more conservative in avoiding risk than most large insurers. For example, if the insurance industry should experience a $250 billion loss from some mega-catastrophe - a loss about triple anything it has ever experienced - Berkshire as a whole would likely record a large profit for the year. Our many streams of non-insurance earnings would see to that. Additionally, we would remain awash in cash and be eager to write business in an insurance market that might well be in disarray. Meanwhile, other major insurers and reinsurers would be swimming in red ink, if not facing insolvency.

When Ajit entered Berkshire's office on a Saturday in 1986, he did not have a day's experience in the insurance business. Nevertheless, Mike Goldberg, then our manager of insurance, handed him the keys to our small and struggling reinsurance business. With that move, Mike achieved sainthood: Since then, Ajit has created tens of billions of value for Berkshire shareholders. If there were ever to be another Ajit and you could swap me for him, don't hesitate. Make the trade!

* * * * * * * * * * * *

We have another reinsurance powerhouse in General Re, managed until recently by Tad Montross. After 39 years at General Re, Tad retired in 2016. Tad was a class act in every way and we owe him a ton of thanks. Kara Raiguel, who has worked with Ajit for 16 years, is now CEO of General Re.

At bottom, a sound insurance operation needs to adhere to four disciplines. It must (1) understand all exposures that might cause a policy to incur losses; (2) conservatively assess the likelihood of any exposure actually causing a loss and the probable cost if it does; (3) set a premium that, on average, will deliver a profit after both prospective loss costs and operating expenses are covered; and (4) be willing to walk away if the appropriate premium can't be obtained.

Many insurers pass the first three tests and flunk the fourth. They simply can't turn their back on business that is being eagerly written by their competitors. That old line, "The other guy is doing it, so we must as well," spells trouble in any business, but in none more so than insurance. Tad never listened to that nonsensical excuse for sloppy underwriting, and neither will Kara.

* * * * * * * * * * * *

Finally, there is GEICO, the company that set my heart afire 66 years ago (and for which the flame still burns). GEICO is managed by Tony Nicely, who joined the company at 18 and completed 55 years of service in 2016.

Tony became CEO of GEICO in 1993, and since then the company has been flying. There is no better manager than Tony, who brings his combination of brilliance, dedication and soundness to the job. (The latter quality is essential to sustained success. As Charlie says, it's great to have a manager with a 160 IQ - unless he thinks it's 180.) Like Ajit, Tony has created tens of billions of value for Berkshire.

On my initial visit to GEICO in 1951, I was blown away by the huge cost advantage the company enjoyed over the giants of the industry. It was clear to me that GEICO would succeed because it deserved to succeed. The company's annual sales were then $8 million; In 2016, GEICO did that much business every three hours of the year.

Auto insurance is a major expenditure for most families. Savings matter to them - and only a low-cost operation can deliver those. In fact, at least 40% of the people reading this letter can save money by insuring with GEICO. So stop reading - right now! - and go to geico.com or call 800-847-7536.

GEICO's low costs create a moat - an enduring one - that competitors are unable to cross. As a result, the company gobbles up market share year after year, ending 2016 with about 12% of industry volume. That's up from 2.5% in 1995, the year Berkshire acquired control of GEICO. Employment, meanwhile, grew from 8,575 to 36,085.

GEICO's growth accelerated dramatically during the second half of 2016. Loss costs throughout the auto-insurance industry had been increasing at an unexpected pace and some competitors lost their enthusiasm for taking on new customers. GEICO's reaction to the profit squeeze, however, was to accelerate its new-business efforts. We like to make hay while the sun sets, knowing that it will surely rise again.

GEICO continues on a roll as I send you this letter. When insurance prices increase, people shop more. And when they shop, GEICO wins.

Have you called yet? (800-847-7536 or go to geico.com)

In addition to our three major insurance operations, we own a collection of smaller companies that primarily write commercial coverages. In aggregate, these companies are a large, growing and valuable operation that consistently delivers an underwriting profit, usually one much superior to that reported by their competitors. Over the past 14 years, this group has earned $4.7 billion from underwriting - about 13% of its premium volume - while increasing its float from $943 million to $11.6 billion.

Less than three years ago, we formed Berkshire Hathaway Specialty Insurance ("BHSI"), which is included in this grouping. Our first decision was to put Peter Eastwood in charge, a move that proved to be a home run: We expected significant losses in the early years while Peter built the personnel and infrastructure needed for a world-wide operation. Instead, he and his crew delivered significant underwriting profits throughout the start-up period. BHSI's volume increased 40% in 2016, reaching $1.3 billion. It's clear to me that the company is destined to become one of the world's leading P/C insurers.

Berkshire's great managers, premier financial strength and a range of business models protected by wide moats amount to something unique in the insurance world. This assemblage of strengths is a huge asset for Berkshire shareholders that time will only make more valuable.

Regulated, Capital-Intensive Businesses

Our BNSF railroad and Berkshire Hathaway Energy ("BHE"), our 90%-owned utility business, share important characteristics that distinguish them from Berkshire's other activities. Consequently, we assign them their own section in this letter and split out their combined financial statistics in our GAAP balance sheet and income statement. These two very major companies accounted for 33% of Berkshire's after-tax operating earnings last year.

A key characteristic of both companies is their huge investment in very long-lived, regulated assets, with these partially funded by large amounts of long-term debt that is not guaranteed by Berkshire. Our credit is in fact not needed because each company has earning power that even under terrible economic conditions would far exceed its interest requirements. Last year, for example, in a disappointing year for railroads, BNSF's interest coverage was more than 6:1. (Our definition of coverage is the ratio of earnings before interest and taxes to interest, not EBITDA/interest, a commonly-used measure we view as seriously flawed.)

At BHE, meanwhile, two factors ensure the company's ability to service its debt under all circumstances. The first is common to all utilities: recession-resistant earnings, which result from these companies offering an essential service for which demand is remarkably steady. The second is enjoyed by few other utilities: an ever-widening diversity of earnings streams, which shield BHE from being seriously harmed by any single regulatory body. These many sources of profit, supplemented by the inherent advantage of the company being owned by a strong parent, have allowed BHE and its utility subsidiaries to significantly lower their cost of debt. That economic fact benefits both us and our customers.

All told, BHE and BNSF invested $8.9 billion in plant and equipment last year, a massive commitment to their segments of America's infrastructure. We relish making such investments as long as they promise reasonable returns - and, on that front, we put a large amount of trust in future regulation.

Our confidence is justified both by our past experience and by the knowledge that society will forever need huge investments in both transportation and energy. It is in the self-interest of governments to treat capital providers in a manner that will ensure the continued flow of funds to essential projects. It is concomitantly in our self-interest to conduct our operations in a way that earns the approval of our regulators and the people they represent.

Low prices are a powerful way to keep these constituencies happy. In Iowa, BHE's average retail rate is 7.1? per KWH. Alliant, the other major electric utility in the state, averages 9.9?. Here are the comparable industry figures for adjacent states: Nebraska 9.0?, Missouri 9.5?, Illinois 9.2?, Minnesota 10.0?. The national average is 10.3?. We have promised Iowans that our base rates will not increase until 2029 at the earliest. Our rock-bottom prices add up to real money for paycheck-strapped customers.

At BNSF, price comparisons between major railroads are far more difficult to make because of significant differences in both their mix of cargo and the average distance the load is carried. To supply a very crude measure, however, our revenue per ton-mile was 3? last year, while shipping costs for customers of the other four major U.S.-based railroads ranged from 4? to 5?.

Both BHE and BNSF have been leaders in pursuing planet-friendly technology. In wind generation, no state comes close to rivaling Iowa, where last year the megawatt-hours we generated from wind equaled 55% of all megawatt-hours sold to our Iowa retail customers. New wind projects that are underway will take that figure to 89% by 2020.

Bargain-basement electric rates carry second-order benefits with them. Iowa has attracted large high-tech installations, both because of its low prices for electricity (which data centers use in huge quantities) and because most tech CEOs are enthusiastic about using renewable energy. When it comes to wind energy, Iowa is the Saudi Arabia of America.

BNSF, like other Class I railroads, uses only a single gallon of diesel fuel to move a ton of freight almost 500 miles. Those economics make railroads four times as fuel-efficient as trucks! Furthermore, railroads alleviate highway congestion - and the taxpayer-funded maintenance expenditures that come with heavier traffic - in a major way.

All told, BHE and BNSF own assets that are of major importance to our country as well as to shareholders of Berkshire. Here are the key financial figures for both:

HomeServices may appear out of place in the above table. But it came with our purchase of MidAmerican (now BHE) in 1999 - and we are lucky that it did.

HomeServices owns 38 realty companies with more than 29,000 agents who operate in 28 states. Last year it purchased four realtors, including Houlihan Lawrence, the leader in New York's Westchester County (in a transaction that closed shortly after yearend).

In real estate parlance, representing either a buyer or a seller is called a "side," with the representation of both counting as two sides. Last year, our owned realtors participated in 244,000 sides, totaling $86 billion in volume.

HomeServices also franchises many operations throughout the country that use our name. We like both aspects of the real estate business and expect to acquire many realtors and franchisees during the next decade.

Manufacturing, Service and Retailing Operations

Our manufacturing, service and retailing operations sell products ranging from lollipops to jet airplanes. Let's look, though, at a summary balance sheet and earnings statement for the entire group.

Included in this financial summary are 44 businesses that report directly to headquarters. But some of these companies, in turn, have many individual operations under their umbrella. For example, Marmon has 175 separate business units, serving widely disparate markets, and Berkshire Hathaway Automotive owns 83 dealerships, operating in nine states.

This collection of businesses is truly a motley crew. Some operations, measured by earnings on unleveraged net tangible assets, enjoy terrific returns that, in a couple of instances, exceed 100%. Most are solid businesses generating good returns in the area of 12% to 20%.

A few, however - these are serious blunders I made in my job of capital allocation - produce very poor returns. In most cases, I was wrong when I originally sized up the economic characteristics of these companies or the industries in which they operate, and we are now paying the price for my misjudgments. In a couple of instances, I stumbled in assessing either the fidelity or ability of incumbent managers or ones I later put in place. I will commit more errors; you can count on that. Fortunately, Charlie - never bashful - is around to say "no" to my worst ideas.

Viewed as a single entity, the companies in the manufacturing, service and retailing group are an excellent business. They employed an average of $24 billion of net tangible assets during 2016 and, despite their holding large quantities of excess cash and carrying very little debt, earned 24% after-tax on that capital.

Of course, a business with terrific economics can be a bad investment if it is bought at too high a price. We have paid substantial premiums to net tangible assets for most of our businesses, a cost that is reflected in the large figure we show on our balance sheet for goodwill and other intangibles. Overall, however, we are getting a decent return on the capital we have deployed in this sector. Absent a recession, earnings from the group will likely grow in 2017, in part because Duracell and Precision Castparts (both bought in 2016) will for the first time contribute a full year's earnings to this group. Additionally, Duracell incurred significant transitional costs in 2016 that will not recur.

We have far too many companies in this group to comment on them individually. Moreover, their competitors - both current and potential - read this report. In a few of our businesses, we might be disadvantaged if outsiders knew our numbers. Therefore, in certain of our operations that are not of a size material to an evaluation of Berkshire, we only disclose what is required. You can nevertheless find a good bit of detail about many of our operations on pages 90 - 94. Be aware, though, that it's the growth of the Berkshire forest that counts. It would be foolish to focus over-intently on any single tree.

For several years I have told you that the income and expense data shown in this section does not conform to GAAP. I have explained that this divergence occurs primarily because of GAAP-ordered rules regarding purchase-accounting adjustments that require the full amortization of certain intangibles over periods averaging about 19 years. In our opinion, most of those amortization "expenses" are not truly an economic cost. Our goal in diverging from GAAP in this section is to present the figures to you in a manner reflecting the way in which Charlie and I view and analyze them.

On page 54 we itemize $15.4 billion of intangibles that are yet to be amortized by annual charges to earnings. (More intangibles to be amortized will be created as we make new acquisitions.) On that page, we show that the 2016 amortization charge to GAAP earnings was $1.5 billion, up $384 million from 2015. My judgment is that about 20% of the 2016 charge is a "real" cost.

Eventually amortization charges fully write off the related asset. When that happens - most often at the 15-year mark - the GAAP earnings we report will increase without any true improvement in the underlying economics of Berkshire's business. (My gift to my successor.)

Now that I've described a GAAP expense that I believe to be overstated, let me move on to a less pleasant distortion produced by accounting rules. The subject this time is GAAP-prescribed depreciation charges, which are necessarily based on historical cost. Yet in certain cases, those charges materially understate true economic costs. Countless words were written about this phenomenon in the 1970s and early 1980s, when inflation was rampant. As inflation subsided - thanks to heroic actions by Paul Volcker - the inadequacy of depreciation charges became less of an issue. But the problem still prevails, big time, in the railroad industry, where current costs for many depreciable items far outstrip historical costs. The inevitable result is that reported earnings throughout the railroad industry are considerably higher than true economic earnings.

At BNSF, to get down to particulars, our GAAP depreciation charge last year was $2.1 billion. But were we to spend that sum and no more annually, our railroad would soon deteriorate and become less competitive. The reality is that - simply to hold our own - we need to spend far more than the cost we show for depreciation. Moreover, a wide disparity will prevail for decades.

All that said, Charlie and I love our railroad, which was one of our better purchases.

Too many managements - and the number seems to grow every year - are looking for any means to report, and indeed feature, "adjusted earnings" that are higher than their company's GAAP earnings. There are many ways for practitioners to perform this legerdemain. Two of their favorites are the omission of "restructuring costs" and "stock-based compensation" as expenses.

Charlie and I want managements, in their commentary, to describe unusual items - good or bad - that affect the GAAP numbers. After all, the reason we look at these numbers of the past is to make estimates of the future. But a management that regularly attempts to wave away very real costs by highlighting "adjusted per-share earnings" makes us nervous. That's because bad behavior is contagious: CEOs who overtly look for ways to report high numbers tend to foster a culture in which subordinates strive to be "helpful" as well. Goals like that can lead, for example, to insurers underestimating their loss reserves, a practice that has destroyed many industry participants.

Charlie and I cringe when we hear analysts talk admiringly about managements who always "make the numbers." In truth, business is too unpredictable for the numbers always to be met. Inevitably, surprises occur. When they do, a CEO whose focus is centered on Wall Street will be tempted to make up the numbers.

Let's get back to the two favorites of "don't-count-this" managers, starting with "restructuring." Berkshire, I would say, has been restructuring from the first day we took over in 1965. Owning only a northern textile business then gave us no other choice. And today a fair amount of restructuring occurs every year at Berkshire. That's because there are always things that need to change in our hundreds of businesses. Last year, as I mentioned earlier, we spent significant sums getting Duracell in shape for the decades ahead.

We have never, however, singled out restructuring charges and told you to ignore them in estimating our normal earning power. If there were to be some truly major expenses in a single year, I would, of course, mention it in my commentary. Indeed, when there is a total rebasing of a business, such as occurred when Kraft and Heinz merged, it is imperative that for several years the huge one-time costs of rationalizing the combined operations be explained clearly to owners. That's precisely what the CEO of Kraft Heinz has done, in a manner approved by the company's directors (who include me). But, to tell owners year after year, "Don't count this," when management is simply making business adjustments that are necessary, is misleading. And too many analysts and journalists fall for this baloney.

To say "stock-based compensation" is not an expense is even more cavalier. CEOs who go down that road are, in effect, saying to shareholders, "If you pay me a bundle in options or restricted stock, don't worry about its effect on earnings. I'll 'adjust' it away."

To explore this maneuver further, join me for a moment in a visit to a make-believe accounting laboratory whose sole mission is to juice Berkshire's reported earnings. Imaginative technicians await us, eager to show their stuff.

Listen carefully while I tell these enablers that stock-based compensation usually comprises at least 20% of total compensation for the top three or four executives at most large companies. Pay attention, too, as I explain that Berkshire has several hundred such executives at its subsidiaries and pays them similar amounts, but uses only cash to do so. I further confess that, lacking imagination, I have counted all of these payments to Berkshire's executives as an expense.

My accounting minions suppress a giggle and immediately point out that 20% of what is paid these Berkshire managers is tantamount to "cash paid in lieu of stock-based compensation" and is therefore not a "true" expense. So - presto! - Berkshire, too, can have "adjusted" earnings.

Back to reality: If CEOs want to leave out stock-based compensation in reporting earnings, they should be required to affirm to their owners one of two propositions: why items of value used to pay employees are not a cost or why a payroll cost should be excluded when calculating earnings.

During the accounting nonsense that flourished during the 1960s, the story was told of a CEO who, as his company revved up to go public, asked prospective auditors, "What is two plus two?" The answer that won the assignment, of course, was, "What number do you have in mind?"

Finance and Financial Products

Our three leasing and rental operations are conducted by CORT (furniture), XTRA (semi-trailers), and Marmon (primarily tank cars but also freight cars, intermodal tank containers and cranes). Each is the leader in its field.

We also include Clayton Homes in this section. This company receives most of its revenue from the sale of manufactured homes, but derives the bulk of its earnings from its large mortgage portfolio. Last year, Clayton became America's largest home builder, delivering 42,075 units that accounted for 5% of all new American homes. (In fairness, other large builders do far more dollar volume than Clayton because they sell site-built homes that command much higher prices.)

In 2015, Clayton branched out, purchasing its first site-builder. Two similar acquisitions followed in 2016, and more will come. Site-built houses are expected to amount to 3% or so of Clayton's unit sales in 2017 and will likely deliver about 14% of its dollar volume.

Even so, Clayton's focus will always be manufactured homes, which account for about 70% of new American homes costing less than $150,000. Clayton manufactures close to one-half of the total. That is a far cry from Clayton's position in 2003 when Berkshire purchased the company. It then ranked third in the industry in units sold and employed 6,731 people. Now, when its new acquisitions are included, the employee count is 14,677. And that number will increase in the future.

Clayton's earnings in recent years have materially benefited from extraordinarily low interest rates. The company's mortgage loans to home-buyers are at fixed-rates and for long terms (averaging 25 years at inception). But Clayton's own borrowings are short-term credits that re-price frequently. When rates plunge, Clayton's earnings from its portfolio greatly increase. We normally would shun that kind of lend-long, borrow-short approach, which can cause major problems for financial institutions. As a whole, however, Berkshire is always asset-sensitive, meaning that higher short-term rates will benefit our consolidated earnings, even as they hurt at Clayton.

Last year Clayton had to foreclose on 8,304 manufactured-housing mortgages, about 2.5% of its total portfolio. Customer demographics help explain that percentage. Clayton's customers are usually lower-income families with mediocre credit scores; many are supported by jobs that will be at risk in any recession; many, similarly, have financial profiles that will be damaged by divorce or death to an extent that would not be typical for a high-income family. Those risks that our customers face are partly mitigated because almost all have a strong desire to own a home and because they enjoy reasonable monthly payments that average only $587, including the cost of insurance and property taxes.

Clayton also has long had programs that help borrowers through difficulties. The two most popular are loan extensions and payment forgiveness. Last year about 11,000 borrowers received extensions, and 3,800 had $3.4 million of scheduled payments permanently canceled by Clayton. The company does not earn interest or fees when these loss-mitigation moves are made. Our experience is that 93% of borrowers helped through these programs in the last two years now remain in their homes. Since we lose significant sums on foreclosures - losses last year totaled $150 million - our assistance programs end up helping Clayton as well as its borrowers.

Clayton and Berkshire have been a wonderful partnership. Kevin Clayton came to us with a best-in-class management group and culture. Berkshire, in turn, provided unmatched staying power when the manufactured-home industry fell apart during the Great Recession. (As other lenders to the industry vanished, Clayton supplied credit not only to its own dealers but also to dealers who sold the products of its competitors.) At Berkshire, we never count on synergies when we acquire companies. Truly important ones, however, surfaced after our purchase of Clayton.

Marmon's railcar business experienced a major slowdown in demand last year, which will cause earnings to decline in 2017. Fleet utilization was 91% in December, down from 97% a year earlier, with the drop particularly severe at the large fleet we purchased from General Electric in 2015. Marmon's crane and container rentals have weakened as well.

Big swings in railcar demand have occurred in the past and they will continue. Nevertheless, we very much like this business and expect decent returns on equity capital over the years. Tank cars are Marmon's specialty. People often associate tank cars with the transportation of crude oil; in fact, they are essential to a great variety of shippers.

Over time, we expect to expand our railcar operation. Meanwhile, Marmon is making a number of bolt-on acquisitions whose results are included in the Manufacturing, Service and Retailing section.

Here's the pre-tax earnings recap for our finance-related companies:


Below we list our fifteen common stock investments that at yearend had the largest market value. We exclude our Kraft Heinz (KHC) holding because Berkshire is part of a control group and therefore must account for this investment on the "equity" method. The 325,442,152 shares Berkshire owns of Kraft Heinz are carried on our balance sheet at a GAAP figure of $15.3 billion and had a yearend market value of $28.4 billion. Our cost basis for the shares is $9.8 billion.

Some of the stocks in the table are the responsibility of either Todd Combs or Ted Weschler, who work with me in managing Berkshire's investments. Each, independently, manages more than $10 billion; I usually learn about decisions they have made by looking at monthly trade sheets. Included in the $21 billion that the two manage is about $7.6 billion of pension trust assets of certain Berkshire subsidiaries. As noted, pension investments are not included in the preceding tabulation of Berkshire holdings.

* * * * * * * * * * * *

Excluded from the table - but important - is our ownership of $5 billion of preferred stock issued by Bank of America (BAC). This stock, which pays us $300 million per year, also carries with it a valuable warrant allowing Berkshire to purchase 700 million common shares of Bank of America for $5 billion at any time before September 2, 2021. At yearend, that privilege would have delivered us a profit of $10.5 billion. If it wishes, Berkshire can use its preferred shares to satisfy the $5 billion cost of exercising the warrant.

If the dividend rate on Bank of America common stock - now 30 cents annually - should rise above 44 cents before 2021, we would anticipate making a cashless exchange of our preferred into common. If the common dividend remains below 44 cents, it is highly probable that we will exercise the warrant immediately before it expires.

Many of our investees, including Bank of America, have been repurchasing shares, some quite aggressively. We very much like this behavior because we believe the repurchased shares have in most cases been underpriced. (Undervaluation, after all, is why we own these positions.) When a company grows and outstanding shares shrink, good things happen for shareholders.

* * * * * * * * * * * *

It's important for you to understand that 95% of the $86 billion of "cash and equivalents" (which in my mind includes U.S. Treasury Bills) shown on our balance sheet are held by entities in the United States and, consequently, is not subject to any repatriation tax. Moreover, repatriation of the remaining funds would trigger only minor taxes because much of that money has been earned in countries that themselves impose meaningful corporate taxes. Those payments become an offset to U.S. tax when money is brought home.

These explanations are important because many cash-rich American companies hold a large portion of their funds in jurisdictions imposing very low taxes. Such companies hope - and may well be proved right - that the tax levied for bringing these funds to America will soon be materially reduced. In the meantime, these companies are limited as to how they can use that cash. In other words, off-shore cash is simply not worth as much as cash held at home.

Berkshire has a partial offset to the favorable geographical location of its cash, which is that much of it is held in our insurance subsidiaries. Though we have many alternatives for investing this cash, we do not have the unlimited choices that we would enjoy if the cash were held by the parent company, Berkshire. We do have an ability annually to distribute large amounts of cash from our insurers to the parent - though here, too, there are limits. Overall, cash held at our insurers is a very valuable asset, but one slightly less valuable to us than is cash held at the parent level.

* * * * * * * * * * * *

Sometimes the comments of shareholders or media imply that we will own certain stocks "forever." It is true that we own some stocks that I have no intention of selling for as far as the eye can see (and we're talking 20/20 vision). But we have made no commitment that Berkshire will hold any of its marketable securities forever.

Confusion about this point may have resulted from a too-casual reading of Economic Principle 11 on pages 110 - 111, which has been included in our annual reports since 1983. That principle covers controlled businesses, not marketable securities. This year I've added a final sentence to #11 to ensure that our owners understand that we regard any marketable security as available for sale, however unlikely such a sale now seems.

Before we leave this investment section, a few educational words about dividends and taxes: Berkshire, like most corporations, nets considerably more from a dollar of dividends than it reaps from a dollar of capital gains. That will probably surprise those of our shareholders who are accustomed to thinking of capital gains as the route to tax-favored returns.

But here's the corporate math. Every $1 of capital gains that a corporation realizes carries with it 35 cents of federal income tax (and often state income tax as well). The tax on dividends received from domestic corporations, however, is consistently lower, though rates vary depending on the status of the recipient.

For a non-insurance company - which describes Berkshire Hathaway, the parent - the federal tax rate is effectively 101/ 2 cents per $1 of dividends received. Furthermore, a non-insurance company that owns more than 20% of an investee owes taxes of only 7 cents per $1 of dividends. That rate applies, for example, to the substantial dividends we receive from our 27% ownership of Kraft Heinz, all of it held by the parent company. (The rationale for the low corporate taxes on dividends is that the dividend-paying investee has already paid its own corporate tax on the earnings being distributed.)

Berkshire's insurance subsidiaries pay a tax rate on dividends that is somewhat higher than that applying to non-insurance companies, though the rate is still well below the 35% hitting capital gains. Property/casualty companies owe about 14% in taxes on most dividends they receive. Their tax rate falls, though, to about 11% if they own more than 20% of a U.S.-based investee.

And that's our tax lesson for today.
