Inside Back CoverCharlie Munger – The Architect of Berkshire Hathaway
Charlie Munger died on November 28, just 33 days before his 100th birthday.
Though born and raised in Omaha, he spent 80% of his life domiciled
elsewhere. Consequently, it was not until 1959 when he was 35 that I first met him.
In 1962, he decided that he should take up money management.
Three years later he told me – correctly! – that I had made a dumb decision inbuying control of Berkshire. But, he assured me, since I had already made the move,
he would tell me how to correct my mistake.
In what I next relate, bear in mind that Charlie and his family did not have adime invested in the small investing partnership that I was then managing and whosemoney I had used for the Berkshire purchase. Moreover, neither of us expected thatCharlie would ever own a share of Berkshire stock.
Nevertheless, Charlie, in 1965, promptly advised me: “Warren, forget about
ever buying another company like Berkshire. But now that you control Berkshire, add
to it wonderful businesses purchased at fair prices and give up buying fair businesses
at wonderful prices. In other words, abandon everything you learned from your hero,
Ben Graham. It works but only when practiced at small scale.” With much back-sliding
I subsequently followed his instructions.
Many years later, Charlie became my partner in running Berkshire and,repeatedly, jerked me back to sanity when my old habits surfaced. Until his death, hecontinued in this role and together we, along with those who early on invested withus, ended up far better off than Charlie and I had ever dreamed possible.
In reality, Charlie was the “architect” of the present Berkshire, and I acted as
the “general contractor” to carry out the day-by-day construction of his vision.
Charlie never sought to take credit for his role as creator but instead let metake the bows and receive the accolades. In a way his relationship with me was partolder brother, part loving father. Even when he knew he was right, he gave me thereins, and when I blundered he never – never –reminded me of my mistake.
In the physical world, great buildings are linked to their architect while those
who had poured the concrete or installed the windows are soon forgotten. Berkshire
has become a great company. Though I have long been in charge of the construction
crew; Charlie should forever be credited with being the architect.

BERKSHIRE HATHAWAY INC.

To the Shareholders of Berkshire Hathaway Inc.:
Berkshire has more than three million shareholder accounts. I am charged with writing a
letter every year that will be useful to this diverse and ever-changing group of owners, many ofwhom wish to learn more about their investment.
Charlie Munger, for decades my partner in managing Berkshire, viewed this obligation
identically and would expect me to communicate with you this year in the regular manner. He andI were of one mind regarding our responsibilities to Berkshire shareholders.
************
Writers find it useful to picture the reader they seek, and often they are hoping to attract amass audience. At Berkshire, we have a more limited target: investors who trust Berkshire with
their savings without any expectation of resale (resembling in attitude people who save in order tobuy a farm or rental property rather than people who prefer using their excess funds to purchaselottery tickets or “hot” stocks).
Over the years, Berkshire has attracted an unusual number of such “lifetime” shareholders
and their heirs. We cherish their presence and believe they are entitled to hear every year both thegood and bad news, delivered directly from their CEO and not from an investor-relations officer
or communications consultant forever serving up optimism and syrupy mush.
In visualizing the owners that Berkshire seeks, I am lucky to have the perfect mental model,
my sister, Bertie. Let me introduce her.
For openers, Bertie is smart, wise and likes to challenge my thinking. We have never,
however, had a shouting match or anything close to a ruptured relationship. We never will.
Furthermore, Bertie, and her three daughters as well, have a large portion of their savingsin Berkshire shares. Their ownership spans decades, and every year Bertie will read what I haveto say. My job is to anticipate her questions and give her honest answers.

3

Bertie, like most of you, understands many accounting terms, but she is not ready for a
CPA exam. She follows business news – reading four newspapers daily – but doesn’t consider
herself an economic expert. She is sensible – very sensible – instinctively knowing that pundits
should always be ignored. After all, if she could reliably predict tomorrow’s winners, would she
freely share her valuable insights and thereby increase competitive buying? That would be likefinding gold and then handing a map to the neighbors showing its location.
Bertie understands the power – for good or bad – of incentives, the weaknesses of humans,
the “tells” that can be recognized when observing human behavior. She knows who is “selling”
and who can be trusted. In short, she is nobody’s fool.
So, what would interest Bertie this year?
Operating Results, Fact and Fiction
Let’s begin with the numbers. The official annual report begins on K-1 and extends for 124
pages. It is filled with a vast amount of information – some important, some trivial.
Among its disclosures many owners, along with financial reporters, will focus on page
K-72. There, they will find the proverbial “bottom line” labeled “Net earnings (loss).” The
numbers read $90 billion for 2021, ($23 billion) for 2022 and $96 billion for 2023.
What in the world is going on?
You seek guidance and are told that the procedures for calculating these “earnings” arepromulgated by a sober and credentialed Financial Accounting Standards Board (“FASB”),
mandated by a dedicated and hard-working Securities and Exchange Commission (“SEC”) andaudited by the world-class professionals at Deloitte & Touche (“D&T”). On page K-67, D&T pulls
no punches: “In our opinion, the financial statements . . . . . present fairly, in all material respects(italics mine), the financial position of the Company . . . . . and the results of its operations . . . . .
for each of the three years in the period ended December 31, 2023 . . . . .”So sanctified, this worse-than-useless “net income” figure quickly gets transmitted
throughout the world via the internet and media. All parties believe they have done their job – and,legally, they have.
We, however, are left uncomfortable. At Berkshire, our view is that “earnings” should be asensible concept that Bertie will find somewhat useful – but only as a starting point – inevaluating a business. Accordingly, Berkshire also reports to Bertie and you what we call
“operating earnings.” Here is the story they tell: $27.6 billion for 2021; $30.9 billion for 2022 and$37.4 billion for 2023.

4

The primary difference between the mandated figures and the ones Berkshire prefers is that
we exclude unrealized capital gains or losses that at times can exceed $5 billion a day. Ironically,
our preference was pretty much the rule until 2018, when the “improvement” was mandated.
Galileo’s experience, several centuries ago, should have taught us not to mess with mandates fromon high. But, at Berkshire, we can be stubborn.
************
Make no mistake about the significance of capital gains: I expect them to be a very
important component of Berkshire’s value accretion during the decades ahead. Why else would
we commit huge dollar amounts of your money (and Bertie’s) to marketable equities just as I havebeen doing with my own funds throughout my investing lifetime?
I can’t remember a period since March 11, 1942 – the date of my first stock purchase – that
I have not had a majority of my net worth in equities, U.S.-based equities. And so far, so good.
The Dow Jones Industrial Average fell below 100 on that fateful day in 1942 when I “pulled thetrigger.” I was down about $5 by the time school was out. Soon, things turned around and now thatindex hovers around 38,000. America has been a terrific country for investors. All they haveneeded to do is sit quietly, listening to no one.
It is more than silly, however, to make judgments about Berkshire’s investment value basedon “earnings” that incorporate the capricious day-by-day and, yes, even year-by-year movementsof the stock market. As Ben Graham taught me, “In the short run the market acts as a voting
machine; in the long run it becomes a weighing machine.”
What We Do
Our goal at Berkshire is simple: We want to own either all or a portion of businesses thatenjoy good economics that are fundamental and enduring. Within capitalism, some businesses will
flourish for a very long time while others will prove to be sinkholes. It’s harder than you would
think to predict which will be the winners and losers. And those who tell you they know the answer
are usually either self-delusional or snake-oil salesmen.
At Berkshire, we particularly favor the rare enterprise that can deploy additional capital athigh returns in the future. Owning only one of these companies – and simply sitting tight – candeliver wealth almost beyond measure. Even heirs to such a holding can – ugh! – sometimes live
a lifetime of leisure.
We also hope these favored businesses are run by able and trustworthy managers, thoughthat is a more difficult judgment to make, however, and Berkshire has had its shareof disappointments.

5

In 1863, Hugh McCulloch, the first Comptroller of the United States, sent a letter to all
national banks. His instructions included this warning: “Never deal with a rascal under the
expectation that you can prevent him from cheating you.” Many bankers who thought they could“manage” the rascal problem have learned the wisdom of Mr. McCulloch’s advice – and I have as
well. People are not that easy to read. Sincerity and empathy can easily be faked. That is as true
now as it was in 1863.
This combination of the two necessities I’ve described for acquiring businesses has forlong been our goal in purchases and, for a while, we had an abundance of candidates to evaluate.
If I missed one – and I missed plenty – another always came along.
Those days are long behind us; size did us in, though increased competition for purchases
was also a factor.
Berkshire now has – by far – the largest GAAP net worth recorded by any Americanbusiness. Record operating income and a strong stock market led to a yearend figure of $561
billion. The total GAAP net worth for the other 499 S&P companies – a who’s who of Americanbusiness – was $8.9 trillion in 2022. (The 2023 number for the S&P has not yet been tallied but isunlikely to materially exceed $9.5 trillion.)
By this measure, Berkshire now occupies nearly 6% of the universe in which it operates.
Doubling our huge base is simply not possible within, say, a five-year period, particularly because
we are highly averse to issuing shares (an act that immediately juices net worth).
There remain only a handful of companies in this country capable of truly moving theneedle at Berkshire, and they have been endlessly picked over by us and by others. Some we canvalue; some we can’t. And, if we can, they have to be attractively priced. Outside the U.S., there
are essentially no candidates that are meaningful options for capital deployment at Berkshire. All
in all, we have no possibility of eye-popping performance.
Nevertheless, managing Berkshire is mostly fun and always interesting. On the positiveside, after 59 years of assemblage, the company now owns either a portion or 100% of various
businesses that, on a weighted basis, have somewhat better prospects than exist at most large
American companies. By both luck and pluck, a few huge winners have emerged from a great
many dozens of decisions. And we now have a small cadre of long-time managers who never museabout going elsewhere and who regard 65 as just another birthday.
************
Berkshire benefits from an unusual constancy and clarity of purpose. While we emphasize
treating our employees, communities and suppliers well – who wouldn’t wish to do so? – ourallegiance will always be to our country and our shareholders. We never forget that, though yourmoney is comingled with ours, it does not belong to us.

6With that focus, and with our present mix of businesses, Berkshire should do a bit better
than the average American corporation and, more important, should also operate with materiallyless risk of permanent loss of capital. Anything beyond “slightly better,” though, is wishful
thinking. This modest aspiration wasn’t the case when Bertie went all-in on Berkshire – but it
is now.
Our Not-So-Secret Weapon
Occasionally, markets and/or the economy will cause stocks and bonds of some large andfundamentally good businesses to be strikingly mispriced. Indeed, markets can – andwill – unpredictably seize up or even vanish as they did for four months in 1914 and for a few daysin 2001. If you believe that American investors are now more stable than in the past, think back to
September 2008. Speed of communication and the wonders of technology facilitate instantworldwide paralysis, and we have come a long way since smoke signals. Such instant panics won’t
happen often – but they will happen.
Berkshire’s ability to immediately respond to market seizures with both huge sums andcertainty of performance may offer us an occasional large-scale opportunity. Though the stock
market is massively larger than it was in our early years, today’s active participants are neither
more emotionally stable nor better taught than when I was in school. For whatever reasons, markets
now exhibit far more casino-like behavior than they did when I was young. 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 bevigorously 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 lossof 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 alifetime 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.

7

Our goal is realistic. Berkshire’s strength comes from its Niagara of diverse earnings
delivered after interest costs, taxes and substantial charges for depreciation and amortization(“EBITDA” is a banned measurement at Berkshire). We also operate with minimal requirements
for cash, even if the country encounters a prolonged period of global economic weakness, fear andnear-paralysis.
Berkshire does not currently pay dividends, and its share repurchases are 100%
discretionary. Annual debt maturities are never material.
Your company also holds a cash and U.S. Treasury bill position far in excess of whatconventional wisdom deems necessary. During the 2008 panic, Berkshire generated cash fromoperations and did not rely in any manner on commercial paper, bank lines or debt markets. We
did not predict the time of an economic paralysis but we were always prepared for one.
Extreme fiscal conservatism is a corporate pledge we make to those who have joined us inownership of Berkshire. In most years – indeed in most decades – our caution will likely prove to
be unneeded behavior – akin to an insurance policy on a fortress-like building thought to be
fireproof. But Berkshire does not want to inflict permanent financial damage – quotational
shrinkage for extended periods can’t be avoided – on Bertie or any of the individuals who havetrusted us with their savings.
Berkshire is built to last.
Non-controlled Businesses That Leave Us Comfortable
Last year I mentioned two of Berkshire’s long-duration partial-ownership
positions – Coca-Cola and American Express. These are not huge commitments like our Apple
position. Each only accounts for 4-5% of Berkshire’s GAAP net worth. But they are meaningful
assets and also illustrate our thought processes.
American Express began operations in 1850, and Coca-Cola was launched in an Atlanta
drug store in 1886. (Berkshire is not big on newcomers.) Both companies tried expanding into
unrelated areas over the years and both found little success in these attempts. In the past – but
definitely not now – both were even mismanaged.
But each was hugely successful in its base business, reshaped here and there as conditions
called for. And, crucially, their products “traveled.” Both Coke and AMEX became recognizable
names worldwide as did their core products, and the consumption of liquids and the need forunquestioned financial trust are timeless essentials of our world.

8

During 2023, we did not buy or sell a share of either AMEX or Coke – extending our own
Rip Van Winkle slumber that has now lasted well over two decades. Both companies again
rewarded our inaction last year by increasing their earnings and dividends. Indeed, our share of
AMEX earnings in 2023 considerably exceeded the $1.3 billion cost of our long-ago purchase.
Both AMEX and Coke will almost certainly increase their dividends in 2024 – about 16%
in the case of AMEX – and we will most certainly leave our holdings untouched throughout theyear. Could I create a better worldwide business than these two enjoy? As Bertie will tell
you: “No way.”
Though Berkshire did not purchase shares of either company in 2023, your indirectownership of both Coke and AMEX increased a bit last year because of share repurchases we madeat Berkshire. Such repurchases work to increase your participation in every asset that Berkshireowns. To this obvious but often overlooked truth, I add my usual caveat: All stock repurchases
should be price-dependent. What is sensible at a discount to business-value becomes stupid if done
at a premium.
The lesson from Coke and AMEX? When you find a truly wonderful business, stick with
it. Patience pays, and one wonderful business can offset the many mediocre decisions thatare inevitable.
************
This year, I would like to describe two other investments that we expect to maintainindefinitely. Like Coke and AMEX, these commitments are not huge relative to our resources.
They are worthwhile, however, and we were able to increase both positions during 2023.
At yearend, Berkshire owned 27.8% of Occidental Petroleum’s common shares and also
owned warrants that, for more than five years, give us the option to materially increase ourownership at a fixed price. Though we very much like our ownership, as well as the option,
Berkshire has no interest in purchasing or managing Occidental. We particularly like its vast oil
and gas holdings in the United States, as well as its leadership in carbon-capture initiatives, though
the economic feasibility of this technique has yet to be proven. Both of these activities are verymuch in our country’s interest.
Not so long ago, the U.S. was woefully dependent on foreign oil, and carbon capture had
no meaningful constituency. Indeed, in 1975, U.S. production was eight million barrels of
oil-equivalent per day (“BOEPD”), a level far short of the country’s needs. From the favorable
energy position that facilitated the U.S. mobilization in World War II, the country had retreated to
become heavily dependent on foreign – potentially unstable – suppliers. Further declines in oil
production were predicted along with future increases in usage.

9

For a long time, the pessimism appeared to be correct, with production falling to fivemillion BOEPD by 2007. Meanwhile, the U.S. government created a Strategic Petroleum Reserve(“SPR”) in 1975 to alleviate – though not come close to eliminating – this erosion of American
self-sufficiency.
And then – Hallelujah! – shale economics became feasible in 2011, and our energy
dependency ended. Now, U.S. production is more than 13 million BOEPD, and OPEC no longer
has the upper hand. Occidental itself has annual U.S. oil production that each year comes close tomatching the entire inventory of the SPR. Our country would be very – very – nervous today ifdomestic production had remained at five million BOEPD, and it found itself hugely dependent
on non-U.S. sources. At that level, the SPR would have been emptied within months if foreign oil
became unavailable.
Under Vicki Hollub’s leadership, Occidental is doing the right things for both its country
and its owners. No one knows what oil prices will do over the next month, year, or decade. But
Vicki does know how to separate oil from rock, and that’s an uncommon talent, valuable to hershareholders and to her country.
************
Additionally, Berkshire continues to hold its passive and long-term interest in five verylarge Japanese companies, each of which operates in a highly-diversified manner somewhat similar
to the way Berkshire itself is run. We increased our holdings in all five last year after Greg Abeland I made a trip to Tokyo to talk with their managements.
Berkshire now owns about 9% of each of the five. (A minor point: Japanese companies
calculate outstanding shares in a manner different from the practice in the U.S.) Berkshire has also
pledged to each company that it will not purchase shares that will take our holdings beyond 9.9%.
Our cost for the five totals ¥1.6 trillion, and the yearend market value of the five was ¥2.9 trillion.
However, the yen has weakened in recent years and our yearend unrealized gain in dollars was
61% or $8 billion.
Neither Greg nor I believe we can forecast market prices of major currencies. We also don’t
believe we can hire anyone with this ability. Therefore, Berkshire has financed most of its Japaneseposition with the proceeds from ¥1.3 trillion of bonds. This debt has been very well-received inJapan, and I believe Berkshire has more yen-denominated debt outstanding than any other
American company. The weakened yen has produced a yearend gain for Berkshire of $1.9 billion,
a sum that, pursuant to GAAP rules, has periodically been recognized in income over the2020-23 period.
In certain important ways, all five companies – Itochu, Marubeni, Mitsubishi, Mitsui and
Sumitomo – follow shareholder-friendly policies that are much superior to those customarily
practiced in the U.S. Since we began our Japanese purchases, each of the five has reduced thenumber of its outstanding shares at attractive prices.

10Meanwhile, the managements of all five companies have been far less aggressive about
their own compensation than is typical in the United States. Note as well that each of the five isapplying only about 1⁄ 3 of its earnings to dividends. The large sums the five retain are used both tobuild their many businesses and, to a lesser degree, to repurchase shares. Like Berkshire, the fivecompanies are reluctant to issue shares.
An additional benefit for Berkshire is the possibility that our investment may lead toopportunities for us to partner around the world with five large, well-managed and well-respectedcompanies. Their interests are far more broad than ours. And, on their side, the Japanese CEOs
have the comfort of knowing that Berkshire will always possess huge liquid resources that can beinstantly available for such partnerships, whatever their size may be.
Our Japanese purchases began on July 4, 2019. Given Berkshire’s present size, building
positions through open-market purchases takes a lot of patience and an extended period of“friendly” prices. The process is like turning a battleship. That is an important disadvantage which
we did not face in our early days at Berkshire.

At Berkshire’s annual gathering on May 6, 2023, I presented the first quarter’s results
which had been released early that morning. I followed with a short summary of the outlook forthe full year: (1) most of our non-insurance businesses faced lower earnings in 2023; (2) thatdecline would be cushioned by decent results at our two largest non-insurance businesses, BNSF
and Berkshire Hathaway Energy (“BHE”) which, combined, had accounted for more than 30% of
operating earnings in 2022; (3) our investment income was certain to materially grow because thehuge U.S. Treasury bill position held by Berkshire had finally begun to pay us far more than thepittance we had been receiving and (4) insurance would likely do well, both because its
underwriting earnings are not correlated to earnings elsewhere in the economy and, beyond that,property-casualty insurance prices had strengthened.

11

Insurance came through as expected. I erred, however, in my expectations for both BNSF
and BHE. Let’s take a look at each.
************
Rail is essential to America’s economic future. It is clearly the most efficientway – measured by cost, fuel usage and carbon intensity – of moving heavy materials to distantdestinations. Trucking wins for short hauls, but many goods that Americans need must travel tocustomers many hundreds or even several thousands of miles away. The country can’t run without
rail, and the industry’s capital needs will always be huge. Indeed, compared to most Americanbusinesses, railroads eat capital.
BNSF is the largest of six major rail systems that blanket North America. Our railroad
carries its 23,759 miles of main track, 99 tunnels, 13,495 bridges, 7,521 locomotives and assorted
other fixed assets at $70 billion on its balance sheet. But my guess is that it would cost at least$500 billion to replicate those assets and decades to complete the job.
BNSF must annually spend more than its depreciation charge to simply maintain its present
level of business. This reality is bad for owners, whatever the industry in which they have invested,
but it is particularly disadvantageous in capital-intensive industries.
At BNSF, the outlays in excess of GAAP depreciation charges since our purchase 14 years
ago have totaled a staggering $22 billion or more than $1 1⁄ 2 billion annually. Ouch! That sort ofgap means BNSF dividends paid to Berkshire, its owner, will regularly fall considerably short of
BNSF’s reported earnings unless we regularly increase the railroad’s debt. And that we do notintend to do.
Consequently, Berkshire is receiving an acceptable return on its purchase price, though lessthan it might appear, and also a pittance on the replacement value of the property. That’s nosurprise to me or Berkshire’s board of directors. It explains why we could buy BNSF in 2010 at asmall fraction of its replacement value.
North America’s rail system moves huge quantities of coal, grain, autos, imported andexported goods, etc. one-way for long distances and those trips often create a revenue problem forback-hauls. Weather conditions are extreme and frequently hamper or even stymie the utilizationof track, bridges and equipment. Flooding can be a nightmare. None of this is a surprise. While I
sit in an always-comfortable office, railroading is an outdoor activity with many employees
working under trying and sometimes dangerous conditions.
An evolving problem is that a growing percentage of Americans are not looking for thedifficult, and often lonely, employment conditions inherent in some rail operations. Engineers must
deal with the fact that among an American population of 335 million, some forlorn or
mentally-disturbed Americans are going to elect suicide by lying in front of a 100-car,extraordinarily heavy train that can’t be stopped in less than a mile or more. Would you like to be
the helpless engineer? This trauma happens about once a day in North America; it is far morecommon in Europe and will always be with us.

Wage negotiations in the rail industry can end up in the hands of the President andCongress. Additionally, American railroads are required to carry many dangerous products every
day that the industry would much rather avoid. The words “common carrier” define
railroad responsibilities.
Last year BNSF’s earnings declined more than I expected, as revenues fell. Though fuelcosts also fell, wage increases, promulgated in Washington, were far beyond the country’s inflation
goals. This differential may recur in future negotiations.
Though BNSF carries more freight and spends more on capital expenditures than any of
the five other major North American railroads, its profit margins have slipped relative to all fivesince our purchase. I believe that our vast service territory is second to none and that therefore our
margin comparisons can and should improve.
I am particularly proud of both BNSF’s contribution to the country and the people whowork in sub-zero outdoor jobs in North Dakota and Montana winters to keep America’s
commercial arteries open. Railroads don’t get much attention when they are working but, were
they unavailable, the void would be noticed immediately throughout America.
A century from now, BNSF will continue to be a major asset of the country and ofBerkshire. You can count on that.
************
Our second and even more severe earnings disappointment last year occurred at BHE. Mostof its large electric-utility businesses, as well as its extensive gas pipelines, performed about as
expected. But the regulatory climate in a few states has raised the specter of zero profitability oreven bankruptcy (an actual outcome at California’s largest utility and a current threat in Hawaii).
In such jurisdictions, it is difficult to project both earnings and asset values in what was once
regarded as among the most stable industries in America.
For more than a century, electric utilities raised huge sums to finance their growth througha state-by-state promise of a fixed return on equity (sometimes with a small bonus for superior
performance). With this approach, massive investments were made for capacity that would likely
be required a few years down the road. That forward-looking regulation reflected the reality thatutilities build generating and transmission assets that often take many years to construct. BHE’s
extensive multi-state transmission project in the West was initiated in 2006 and remains someyears from completion. Eventually, it will serve 10 states comprising 30% of the acreage in thecontinental United States.
With this model employed by both private and public-power systems, the lights stayed on,even if population growth or industrial demand exceeded expectations. The “margin of safety”
approach seemed sensible to regulators, investors and the public. Now, the fixed-but-satisfactoryreturn pact has been broken in a few states, and investors are becoming apprehensive that such
ruptures may spread. Climate change adds to their worries. Underground transmission may berequired but who, a few decades ago, wanted to pay the staggering costs for such construction?

At Berkshire, we have made a best estimate for the amount of losses that have occurred.
These costs arose from forest fires, whose frequency and intensity have increased – and will likely
continue to increase – if convective storms become more frequent.
It will be many years until we know the final tally from BHE’s forest-fire losses and canintelligently make decisions about the desirability of future investments in vulnerable westernstates. It remains to be seen whether the regulatory environment will change elsewhere.
Other electric utilities may face survival problems resembling those of Pacific Gas andElectric and Hawaiian Electric. A confiscatory resolution of our present problems would obviously
be a negative for BHE, but both that company and Berkshire itself are structured to survive
negative surprises. We regularly get these in our insurance business, where our basic product isrisk assumption, and they will occur elsewhere. Berkshire can sustain financial surprises but wewill not knowingly throw good money after bad.
Whatever the case at Berkshire, the final result for the utility industry may be ominous:
Certain utilities might no longer attract the savings of American citizens and will be forced toadopt the public-power model. Nebraska made this choice in the 1930s and there are many
public-power operations throughout the country. Eventually, voters, taxpayers and users will
decide which model they prefer.
When the dust settles, America’s power needs and the consequent capital expenditure will
be staggering. I did not anticipate or even consider the adverse developments in regulatory returns
and, along with Berkshire’s two partners at BHE, I made a costly mistake in not doing so.
************
Enough about problems: Our insurance business performed exceptionally well last year,
setting records in sales, float and underwriting profits. Property-casualty insurance (“P/C”)
provides the core of Berkshire’s well-being and growth. We have been in the business for 57 years
and despite our nearly 5,000-fold increase in volume – from $17 million to $83 billion – we havemuch room to grow.
Beyond that, we have learned – too often, painfully – a good deal about what types of
insurance business and what sort of people to avoid. The most important lesson is that our
underwriters can be thin, fat, male, female, young, old, foreign or domestic. But they can’t be
optimists at the office, however desirable that quality may generally be in life.
Surprises in the P/C business – which can occur decades after six-month or one-year
policies have expired – are almost always negative. The industry’s accounting is designed torecognize this reality, but estimation mistakes can be huge. And when charlatans are involved,
detection is often both slow and costly. Berkshire will always attempt to be accurate in its estimatesof future loss payments but inflation – both monetary and the “legal” variety – is a wild card.

I’ve told the story of our insurance operations so many times that I will simply direct
newcomers to page 18. Here, I will only repeat that our position would not be what it is if Ajit Jain
had not joined Berkshire in 1986. Before that lucky day – aside from an almost unbelievably
wonderful experience with GEICO that began early in 1951 and will never end – I was largely
wandering in the wilderness, as I struggled to build our insurance operation.
Ajit’s achievements since joining Berkshire have been supported by a large cast of
hugely-talented insurance executives in our various P/C operations. Their names and faces are
unknown to most of the press and the public. Berkshire’s lineup of managers, however, is to P/C
insurance what Cooperstown’s honorees are to baseball.
Bertie, you can feel good about the fact that you own a piece of an incredible P/C operationthat now operates worldwide with unmatched financial resources, reputation and talent. It carried
the day in 2023.
What is it with Omaha?
Come to Berkshire’s annual gathering on May 4, 2024. On stage you will see the threemanagers who now bear the prime responsibilities for steering your company. What, you may
wonder, do the three have in common? They certainly don’t look alike. Let’s dig deeper.
Greg Abel, who runs all non-insurance operations for Berkshire – and in all respects isready to be CEO of Berkshire tomorrow – was born and raised in Canada (he still plays hockey).
In the 1990s, however, Greg lived for six years in Omaha just a few blocks away from me. Duringthat period, I never met him.
A decade or so earlier, Ajit Jain, who was born, raised and educated in India, lived with hisfamily in Omaha only a mile or so from my home (where I’ve lived since 1958). Both Ajit and his
wife, Tinku, have many Omaha friends, though it’s been more than three decades since they moved
to New York (in order to be where much of the action in reinsurance takes place).
Missing from the stage this year will be Charlie. He and I were both born in Omaha about
two miles from where you will sit at our May get-together. In his first ten years, Charlie lived
about a half-mile from where Berkshire has long maintained its office. Both Charlie and I spent
our early years in Omaha public schools and were indelibly shaped by our Omaha childhood. We
didn’t meet, however, until much later. (A footnote that may surprise you: Charlie lived under 15of America’s 45 presidents. People refer to President Biden as #46, but that numbering counts
Grover Cleveland as both #22 and #24 because his terms were not consecutive. America is a very
young country.)

15

Moving to the corporate level, Berkshire itself relocated in 1970 from its 81 years ofresidence in New England to settle in Omaha, leaving its troubles behind and blossoming in its
new home.
As a final punctuation point to the “Omaha Effect,” Bertie – yes that Bertie – spent her
early formative years in a middle-class neighborhood in Omaha and, many decades later, emerged
as one of the country’s great investors.
You may be thinking that she put all of her money in Berkshire and then simply sat on it.
But that’s not true. After starting a family in 1956, Bertie was active financially for 20 years:
holding bonds, putting 1⁄ 3 of her funds in a publicly-held mutual fund and trading stocks with somefrequency. Her potential remained unnoticed.
Then, in 1980, when 46, and independent of any urgings from her brother, Bertie decided
to make her move. Retaining only the mutual fund and Berkshire, she made no new trades during
the next 43 years. During that period, she became very rich, even after making large philanthropic
gifts (think nine figures).
Millions of American investors could have followed her reasoning which involved only
the common sense she had somehow absorbed as a child in Omaha. And, taking no chances, Bertie
returns to Omaha every May to be re-energized.
************
So what is going on? Is it Omaha’s water? Is it Omaha’s air? Is it some strange planetaryphenomenon akin to that which has produced Jamaica’s sprinters, Kenya’s marathon runners, orRussia’s chess experts? Must we wait until AI someday yields the answer to this puzzle?
Keep an open mind. Come to Omaha in May, inhale the air, drink the water and say “hi”
to Bertie and her good-looking daughters. Who knows? There is no downside, and, in any event,you will have a good time and meet a huge crowd of friendly people.
To top things off, we will have available the new 4th edition of Poor Charlie’s Almanack.
Pick up a copy. Charlie’s wisdom will improve your life as it has mine.

BERKSHIRE HATHAWAY INC.
PROPERTY/CASUALTY INSURANCE*
Our property/casualty (“P/C”) insurance business has been the engine propelling Berkshire’s 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
P/C company in the world as measured by net worth. Insurance is a business of promises, and Berkshire’s ability to honor its commitments
is unmatched.
One reason we were attracted to the P/C business was the industry’s business model: P/C insurers receive premiums upfront andpay claims later. In extreme cases, such as claims arising from exposure to asbestos, or severe workplace accidents, 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 toothers. 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:Year

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. That structure is by design and is a key component in the unequaled financial strength of our insurance companies. That
strength 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.
For the P/C industry as a whole, the financial value of float is now far less than it was for many years. That’s because the standard
investment strategy for almost all P/C companies is heavily – and properly – skewed toward high-grade bonds. Changes in interest rates
therefore matter enormously to these companies, and during the last decade the bond market has offered pathetically low rates.
Consequently, insurers suffered, as year by year they were forced – by maturities or issuer-call provisions – to recycle their “old”
investment portfolios into new holdings providing much lower yields. Where once these insurers could safely earn 5 cents or 6 cents oneach dollar of float, they now take in only 2 cents or 3 cents.
Some insurers may try to mitigate their loss of revenue by buying lower-quality bonds or non-liquid “alternative” investments
promising higher yields. But those are dangerous games and activities that most institutions are ill-equipped to play.
Berkshire’s situation is more favorable than that of insurers in general. Most important, our unrivaled mountain of capital,
abundance of cash and a huge and diverse stream of non-insurance earnings allow us far more investment flexibility than is generally
available to other companies in the industry. The many choices open to us are always advantageous – and sometimes have presented us
with major opportunities.
Our P/C companies have meanwhile had an excellent underwriting record. Berkshire has now operated at an underwriting profit
for 18 of the last 20 years, the exceptions being 2017 and 2022. In 2017 our pre-tax loss was a whopping $3.2 billion. In 2022 the loss
was minimal. For the entire 20-year span, our pre-tax gain totaled $29.2 billion.
That record is no accident: Disciplined risk evaluation is the daily focus of our insurance managers, who know that the rewardsof float can be drowned by poor underwriting results. All insurers give that message lip service. At Berkshire it is a religion, Old Testament
style.
As I have repeatedly done in the past, I will emphasize now that happy outcomes in insurance are far from a sure thing: Danger
always lurks.
Mistakes in assessing insurance risks can be huge and can take many years – even decades – to surface and ripen. (Think asbestos.)
A major catastrophe that will dwarf hurricanes Katrina and Ian will occur – perhaps tomorrow, perhaps many decades from now. “The Big One”
may come from a traditional source, such as wind or earthquake, or it may be a total surprise involving, say, a cyber attack having disastrous
consequences beyond anything insurers now contemplate. When such a mega-catastrophe strikes, Berkshire will get its share of the losses andthey will be big – very big. Unlike many other insurers, however, handling the loss will not come close to straining our resources, and we will
be eager to add to our business the next day.

Part I
Item 1. Business Description
Berkshire Hathaway Inc. (“Berkshire,” “Company” or “Registrant”) is a holding company owning subsidiaries engaged
in numerous diverse business activities. The most important of these are insurance businesses conducted on both a primarybasis and a reinsurance basis, a freight rail transportation business and a group of utility and energy generation and distribution
businesses. Berkshire also owns and operates numerous other businesses engaged in a variety of manufacturing, services,
retailing and other activities. Berkshire is domiciled in the state of Delaware, and its corporate headquarters is in Omaha,
Nebraska.
Berkshire’s operating businesses are managed on an unusually decentralized basis. There are few centralized or
integrated business functions. Berkshire’s senior management team participates in and is ultimately responsible for significant
capital allocation decisions, investment activities and the selection of the Chief Executive to head each of the operating
businesses.
Berkshire’s senior management is also responsible for establishing and monitoring Berkshire’s corporate governancepractices, including monitoring governance efforts, including those at the operating businesses, and participating in the
resolution of governance-related issues as needed. Berkshire’s Board of Directors is responsible for assuring an appropriate
successor to the Chief Executive Officer. The Berkshire Code of Business Conduct and Ethics emphasizes, among other things,
the commitment to ethics and compliance with government laws and regulations and provides basic standards for ethical andlegal behavior of its employees.
Human capital and resources are an integral and essential component of Berkshire’s businesses. Berkshire and its
subsidiary business units employed approximately 396,500 people worldwide at the end of 2023, of which approximately 80%
were in the United States (“U.S.”) and 20% were represented by unions. Employees engage in a wide variety of occupations.
Consistent with Berkshire’s decentralized management philosophy, Berkshire’s operating businesses individually establish
specific policies and practices concerning the attraction and retention of personnel within their organizations. Given the wide
variations in the nature and size of business activities, specific policies and practices may vary widely among Berkshire’s
operating subsidiaries. Policies and practices commonly address, among other things: maintaining a safe work environment
and minimizing or eliminating workplace injuries; offering competitive compensation, which includes various health insurance
and retirement benefits, as well as incentives to recognize and reward performance; wellness programs; training, learning andcareer advancement opportunities; and hiring practices intended to identify qualified candidates and promote diversity andinclusion in the workforce. Berkshire’s combined U.S. workforce demographics, based on U.S. Equal Employment Opportunity
Commission guidelines, are available on its website (https://www.berkshirehathaway.com), under sustainability.
Insurance and Reinsurance Businesses
Berkshire’s insurance and reinsurance business activities are conducted through numerous domestic and foreign-based
insurance subsidiaries. Berkshire’s insurance subsidiaries provide insurance and reinsurance of property and casualty risks aswell as life and health risks worldwide. Berkshire’s insurance businesses employed approximately 43,000 people at the end of2023. For purposes of this discussion, entities that provide insurance or reinsurance are referred to as insurers.
In direct or primary insurance activities, the insurer assumes the risk of loss from persons or organizations that are directly
subject to the risks. Such risks may relate to property, casualty (or liability), life, accident, health, financial or other perils thatarise from an insurable event. In reinsurance activities, the insurer assumes defined portions of risks that other direct insurers
or reinsurers assumed in their own insuring activities.
Insurance and reinsurance are generally subject to regulatory oversight throughout the world. Except for regulatory
considerations, there are virtually no barriers to entry into the insurance and reinsurance industry. Competitors may be domestic
or foreign, as well as licensed or unlicensed. The number of competitors within the industry is not known. Insurers compete on
the basis of reliability, financial strength and stability, financial ratings, underwriting consistency, service, business ethics,
price, performance, capacity, policy terms and coverage conditions.
Insurers based in the U.S. are subject to regulation by their states of domicile and by those states in which they arelicensed to write policies on an admitted basis. The primary focus of state regulation is to monitor financial solvency of insurers
and otherwise protect policyholder interests. States establish minimum capital levels for insurance companies and establish
guidelines for permissible business and investment activities and have the authority to suspend or revoke a company’s authority
to do business. States regulate the payment of shareholder dividends by insurance companies and other transactions withaffiliates.

K-1

Insurers that market, sell and service insurance policies in the states where they are licensed are referred to as admitted
insurers. Admitted insurers are generally required to obtain regulatory approval of their policy forms and premium rates. Nonadmitted insurance markets have developed to provide insurance that is otherwise unavailable through admitted insurers. Nonadmitted insurance, often referred to as “excess and surplus” lines, is procured by either state-licensed surplus lines brokers
who place risks with insurers not licensed in that state or by the insured party’s direct procurement from non-admitted insurers.
Non-admitted insurance is subject to considerably less regulation with respect to policy rates and forms. Reinsurers arenormally not required to obtain regulatory approval of premium rates or reinsurance contracts.
The insurance regulators of every state participate in the National Association of Insurance Commissioners (“NAIC”).
The NAIC adopts forms, instructions and accounting procedures for use by U.S. insurers in preparing and filing annual statutoryfinancial statements. However, an insurer’s state of domicile has ultimate authority over these matters. In addition, the NAIC
develops or adopts statutory accounting principles, model laws, regulations and programs for use by its members. Such mattersdeal with regulatory oversight of solvency, risk management, compliance with financial regulation standards and risk-based
capital reporting requirements.
U.S. states, through the NAIC, and international insurance regulators through the International Association of Insurance
Supervisors (“IAIS”) have been developing standards and best practices focused on establishing a common set of principles(“Insurance Core Principles”) and framework (“ComFrame”) for the regulation of large multi-national insurance groups. The
IAIS is developing capital standards for internationally active insurance groups (“Insurance Capital Standard”) based on aconsolidated group approach and is also evaluating a potentially comparable group capital standard based on the aggregationof regulated entities and their underlying local capital requirements (“Aggregation Method”). The IAIS is also developing
standards that address supervision, coordination of regulators, risk management and governance.
While the IAIS standards do not have legal effect, U.S. state insurance departments and the NAIC are implementing
various group supervision regulatory tools and mandates that are responsive to certain IAIS standards. U.S. state regulators
have formed supervisory colleges intended to promote communication and cooperation amongst the various domestic andinternational insurance regulators. The Nebraska Department of Insurance acts as the lead supervisor for Berkshire’s insurancecompanies and chairs the Berkshire supervisory college.
U.S. state regulators require insurance groups to file an annual report and an Own Risk Solvency Assessment or ORSA,
with the group’s lead supervisor. The NAIC adopted a group capital calculation based on methodology similar to theAggregation Method, which leverages the NAIC’s existing risk based capital calculation methods. The NAIC’s group capital
calculation is a tool designed to help the lead supervisor understand the capital adequacy across an insurance group. The NAIC
is also developing further tools, including various liquidity assessments, that will likely be imposed on insurance groups in the
future.
Berkshire’s insurance companies maintain capital strength at exceptionally high levels, which differentiates them fromtheir competitors. The combined statutory surplus of Berkshire’s U.S.-based insurers was approximately $303 billion at
December 31, 2023. Berkshire’s major insurance subsidiaries are rated AA+ by Standard & Poor’s and A++ (superior) by A.M.
Best with respect to their financial condition and claims paying ability.
The Terrorism Risk Insurance Act of 2002 established a Terrorism Insurance Program (“Program”) within the U.S.
Department of the Treasury to provide federal reinsurance of certified terrorism losses incurred by U.S. commercial property
and casualty insurers. The Program currently extends to December 31, 2027 through the Terrorism Risk Insurance Program
Reauthorization Act of 2019. Hereinafter these Acts are collectively referred to as TRIA. The Department of the Treasury is
responsible for certifying acts of terrorism under TRIA. Federal reinsurance under TRIA may apply if the industry insured loss
for certified events occurring during the calendar year exceeds $200 million.
To be eligible for reinsurance under TRIA, insurers must make insurance coverage available for acts of terrorism byproviding policyholders with clear and conspicuous notice of the amount of premium that will be charged for the coverage andthe federal share of insured losses resulting from an act of terrorism. TRIA excludes certain forms of direct insurance, such as
personal and commercial auto, burglary, theft, surety and certain professional liability lines. Reinsurers are not required to offer
terrorism coverage and are not eligible for federal reinsurance of terrorism losses.
In the event of a certified act of terrorism, the federal government will reimburse insurers (conditioned on theirsatisfaction of policyholder notification requirements) for 80% of their insured losses in excess of the insurers group deductible.
Under the Program, the deductible is 20% of the aggregate direct subject earned premium for relevant commercial lines ofbusiness in the immediately preceding calendar year. The aggregate deductible for Berkshire’s insurance group is expected toapproximate $2.5 billion in 2024. There is also an aggregate program limit of $100 billion on the amount of the federal
reinsurance coverage for each TRIA year.

K-2

The extent of insurance regulation varies widely among the countries where Berkshire’s non-U.S. operations conductbusiness. Each country imposes licensing, solvency, auditing and financial reporting requirements, although the type and extent
of the requirements may differ substantially by jurisdiction.
Significant variations can also be found in the size, structure and resources of the local non-U.S. regulatory departmentsthat oversee insurance activities. Certain regulators maintain close relationships with subject insurers and others operate a riskbased approach.
Berkshire’s non-U.S. insurance operations are conducted through subsidiaries and branches of subsidiaries. Berkshire
insurance subsidiaries are located in several countries, including Germany, the United Kingdom (“U.K.”), Ireland,
Luxembourg, Australia and South Africa, and also maintain branches in several other countries. Most of these foreign
jurisdictions impose local capital requirements. Other legal requirements involve discretionary licensing procedures, local
retention of funds and records, and data privacy and protection programs. Berkshire’s international insurance companies arealso subject to multinational application of certain U.S. laws.
There are various regulatory bodies and initiatives that impact Berkshire in multiple international jurisdictions and thepotential for significant effect on the Berkshire insurance group could be heightened due to industry and economic
developments. In 2016, the U.K. voted in a national referendum to withdraw from the European Union (“EU”) (“Brexit”),
which resulted in the U.K.’s withdrawal from the EU on January 31, 2020. In anticipation of the U.K. leaving the EU, Berkshire
Hathaway European Insurance DAC in Ireland was established to permit property and casualty insurance and reinsurance
businesses to continue to operate in the EU. Berkshire also continues to maintain a substantial presence in London following
Brexit.
Berkshire’s insurance underwriting operations include the following groups: (1) GEICO, (2) Berkshire Hathaway
Primary Group and (3) Berkshire Hathaway Reinsurance Group. Alleghany Corporation (“Alleghany”), based in New York,New York, was acquired by Berkshire on October 19, 2022. Alleghany’s operating subsidiaries include property and casualty
reinsurance and insurance, as well as a portfolio of non-insurance businesses. Alleghany’s primary insurance businesses areincluded in the Berkshire Hathaway Primary Group and its reinsurance businesses are included in the Berkshire Hathaway
Reinsurance Group. Alleghany’s non-insurance businesses are included in the manufacturing and services segments.
Except for retroactive reinsurance and periodic payment annuity products, which generate significant amounts of upfront premiums along with estimated claims expected to be paid over long time periods (creating “float,” see Investments
section), Berkshire expects to achieve an underwriting profit over time and that its managers will reject inadequately priced
risks. Underwriting profit is defined as earned premiums less incurred losses, loss adjustment expenses and policy acquisitionand other underwriting expenses. Underwriting profit does not include income earned from investments. Additional information
related to each of Berkshire’s underwriting groups follows.
GEICO—GEICO is headquartered in Chevy Chase, Maryland. GEICO’s insurance subsidiaries are led by Government
Employees Insurance Company and include several other GEICO insurance entities. The GEICO insurance companies offer
private passenger automobile insurance to individuals in all 50 states and the District of Columbia, and also offer insurance formotorcycles, all-terrain vehicles, recreational vehicles, boats and small commercial fleets. Marketing is primarily through direct
response methods in which applications for insurance are submitted directly to the companies via the Internet or by telephone,and to a lesser extent, through captive agents. GEICO also operates as an insurance agency for other insurance carriers thatoffer homeowners, renters, condominium, life and identity protection insurance to individuals desiring insurance coverages
other than those offered by GEICO insurance entities.
GEICO competes for private passenger automobile insurance customers in the preferred, standard and non-standard risk
markets with other companies that sell directly to the customer and with companies that use agency sales forces, including
State Farm, Allstate, Progressive and USAA. According to the most recently published A.M. Best data for 2022, the five largest
automobile insurers had a combined market share of approximately 61.2% based on written premiums, with GEICO’s market
share being the third largest at approximately 13.8%.
Seasonal variations in GEICO’s insurance business are not significant. However, extraordinary weather conditions orother events and factors may have a significant effect upon the frequency or severity of automobile claims.

K-3

State insurance departments stringently regulate private passenger auto insurance policies and rates. Competition for
private passenger automobile insurance tends to focus on price and level of customer service provided. GEICO’s cost-efficient
direct response marketing methods and emphasis on customer satisfaction enable it to offer competitive rates and value to its
customers. GEICO primarily uses its own claims staff to manage and settle claims. The name and reputation of GEICO arematerial assets and those assets and other service marks are protected through appropriate registrations.

Berkshire Hathaway Reinsurance Group—Berkshire’s combined global reinsurance business, referred to as theBerkshire Hathaway Reinsurance Group (“BHRG”), offers a wide range of coverages on property, casualty, life and healthrisks to insurers and reinsurers worldwide. BHRG conducts business activities in 26 countries. Reinsurance business is written
through NICO and affiliates (“NICO Group”), General Re Corporation and its subsidiaries (“General Re Group”) andTransatlantic Reinsurance Company and affiliates (“TransRe Group”). The NICO Group and General Re Group underwriting
operations in the U.S. are based in Stamford, Connecticut and the TransRe Group is based in New York, New York.
Reinsurance contracts are normally classified as treaty or facultative contracts. Treaty reinsurance refers to reinsurance
coverage for all or a portion of a specified group or class of risks ceded by a direct insurer or reinsurer, while facultativereinsurance involves coverage of specific individual underlying risks. Reinsurance contracts are further classified as quotashare or excess. Under quota-share (proportional or pro-rata) reinsurance, the reinsurer shares proportionally in the original
premiums and losses of the direct insurer or reinsurer. Excess (or non-proportional) reinsurance provides for theindemnification of the direct insurer or reinsurer for all or a portion of the loss in excess of an agreed upon amount or“retention.” Both quota-share and excess reinsurance contracts may provide for aggregate limits of indemnification.
The type and volume of business written is dependent on market conditions, including prevailing premium rates andcoverage terms. The level of underwriting activities often fluctuates significantly from year to year depending on the perceived
level of price adequacy in specific insurance and reinsurance markets as well as from the timing of particularly large reinsurance
transactions.
Property/casualty
The NICO Group offers traditional property/casualty reinsurance on both an excess-of-loss and a quota-share basis,
catastrophe excess-of-loss treaty and facultative reinsurance, and primary insurance on an excess-of-loss basis for large or
unusual risks. The type and volume of business written by the NICO Group may vary significantly from period to period
resulting from changes in perceived premium rate adequacy and from unique or large transactions. For the past several years,
a significant portion of NICO Group’s annual reinsurance premium derived from a 20% quota-share agreement with Insurance
Australia Group Limited (“IAG”). This quota-share agreement was renewed and extended effective January 1, 2023, with an
expiration of December 31, 2029. IAG is a multi-line insurer in Australia, New Zealand and other Asia-Pacific countries.
The General Re Group includes a global property and casualty reinsurance business. Reinsurance contracts are written
on both a quota-share and excess basis for multiple lines of business. Contracts are primarily in the form of treaties, and to alesser degree, on a facultative basis. The General Re Group conducts business in North America, primarily marketed on a direct
basis through General Reinsurance Corporation (“GRC”), which is licensed in the District of Columbia and all states, except
Hawaii, where it is an accredited reinsurer. GRC also conducts operations in North America through numerous branch officesin the U.S. and Canada.
In North America, the General Re Group includes General Star National Insurance Company, General Star Indemnity
Company and Genesis Insurance Company, which offer a broad array of specialty and surplus lines and property, casualty andprofessional liability coverages. These companies offer solutions for the unique needs of public entity, commercial and captive
customers and their business is marketed through a select group of wholesale brokers, managing general underwriters andprogram administrators.
The General Re Group’s international reinsurance business is primarily written on a direct basis through General
Reinsurance AG, based in Cologne, Germany, and subsidiaries and branches in numerous other countries, as well as throughbrokers, including Faraday Underwriting Limited (“Faraday”), a subsidiary. Faraday owns the managing agent of Syndicate
435 at Lloyd’s of London and provides capacity and participates in 100% of the results of Syndicate 435.
The TransRe Group provides pro-rata and excess-of-loss reinsurance across various property and casualty lines ofbusiness. Contracts are written on both a treaty and facultative basis to insurance and other reinsurance companies in the U.S.
and in foreign markets through subsidiaries and branches in numerous countries. Business is written primarily through brokers,
and to a lesser extent on a direct basis.
Life/health
The General Re Group also conducts a global life and health reinsurance business. In 2023, net premiums written wereprimarily in the Asia-Pacific, U.S. and Western Europe regions. The General Re Group underwrites life, disability,
supplemental health, critical illness and long-term care risks on a direct basis.

K-5

Berkshire Hathaway Life Insurance Company of Nebraska (“BHLN”) and its affiliates write reinsurance coveringvarious forms of traditional life insurance exposures several years ago. BHLN and affiliates also reinsure certain guaranteed
minimum death, income and similar risks on closed-blocks of variable annuity risks, which are in run-off.
Retroactive reinsurance
Retroactive reinsurance contracts indemnify ceding companies for adverse development of claims arising from loss
events that have already occurred under property and casualty policies issued in prior years. Coverage under such contracts isprovided on an excess basis (above a stated retention) or for losses payable after the inception of the contract with no additional
ceding company retention. Contracts are normally subject to aggregate limits of indemnification, which can be exceptionallylarge in amount. Significant amounts of asbestos, environmental and latent injury claims may arise under these contracts.
The concept of time-value-of-money is an important element in establishing retroactive reinsurance contract prices andterms since loss payments may occur over decades. Normally, expected ultimate losses payable under these policies are
expected to exceed premiums, thus producing underwriting losses through the amortization of deferred charge assets
established with respect to these contracts. Nevertheless, this business is written, in part, because of the large amounts ofpolicyholder funds generated for investment, the economic benefit of which is reflected through investment results in future
periods.
Periodic payment annuity
BHLN writes periodic payment annuity insurance policies and reinsures annuity-like obligations. Under these policies,
BHLN receives upfront consideration and agrees in the future to make periodic payments that often extend for decades. These
policies generally relate to the settlement of underlying personal injury or workers’ compensation claims of other insurers,
known as structured settlements. Consistent with retroactive reinsurance contracts, time-value-of-money is an important factor
in establishing annuity premiums, and underwriting losses are expected from the periodic accretion of time-value discounted
liabilities. BHLN significantly curtailed its periodic payment annuity business in 2023 in response to changing economic andmarket conditions.
Investments of insurance businesses—Berkshire’s insurance subsidiaries hold significant levels of invested assets.
Investment portfolios are managed by Berkshire’s Chief Executive Officer and Berkshire’s other investment managers.
Investments include a very large portfolio of publicly traded equity securities, which are unusually concentrated in relatively
few companies, as well as fixed maturity securities and short-term investments. Generally, there are no target allocations byinvestment type or attempts to match investment asset and insurance liability durations. However, investment portfolios havehistorically included a much greater proportion of equity securities than is customary in the insurance industry.
Invested assets derive from shareholder capital as well as funds provided from policyholders through insurance andreinsurance business (“float”). Float represents the approximate net policyholder funds generated through underwriting
activities that are held for investment. The major components of float are unpaid losses and loss adjustment expenses, life,
annuity and health benefit liabilities (excluding the effects of discount rate changes that are recorded in accumulated othercomprehensive income), unearned premiums and other policyholder liabilities less premium and reinsurance receivables,
deferred policy acquisition costs and deferred charges on assumed retroactive reinsurance contracts. On a consolidated basis,
float has grown from approximately $123 billion at the end of 2018 to approximately $169 billion at the end of 2023. The costof float can be measured as the net pre-tax underwriting earnings (or loss) as a percentage of average float.
Railroad Business—Burlington Northern Santa Fe
Burlington Northern Santa Fe, LLC (“BNSF”) is based in Fort Worth, Texas, and through BNSF Railway Company(“BNSF Railway”) operates one of the largest railroad systems in North America. BNSF Railway had approximately 37,000
employees at the end of 2023, of whom approximately 32,000 were members of a labor union.
In serving the Midwest, Pacific Northwest, Western, Southwestern and Southeastern regions and certain ports of the
U.S., BNSF Railway transports a range of products and commodities derived from manufacturing, agricultural and natural
resource industries. Freight revenues are covered by contractual agreements of varying durations or common carrier publishedprices or company quotations. BNSF’s financial performance is influenced by, among other things, general and industry
economic conditions at the international, national and regional levels.
BNSF Railway’s primary routes, including trackage rights, allow it to access major cities and certain ports in the westernand southern U.S. as well as parts of Canada and Mexico. In addition to major cities and ports, BNSF Railway efficiently serves
many smaller markets by working closely with approximately 200 shortline railroads. BNSF Railway has also entered into
marketing agreements with other rail carriers, expanding the marketing reach for each railroad and their customers. For theyear ending December 31, 2023, 34% of freight revenues were derived from consumer products, 25% from industrial products,
24% from agricultural products and 17% from coal.

K-6

Regulatory Matters
BNSF is subject to federal, state and local laws and regulations generally applicable to its businesses. Rail operations are
subject to the regulatory jurisdiction of the Surface Transportation Board (“STB”), the Federal Railroad Administration of the
U.S. Department of Transportation (“DOT”), the Occupational Safety and Health Administration (“OSHA”), theEnvironmental Protection Agency (“EPA”), as well as other federal and state regulatory agencies and Canadian regulatory
agencies for operations in Canada. The STB has jurisdiction over disputes and complaints involving certain rates, routes andservices, the sale or abandonment of rail lines, applications for line extensions and construction, and the merger with or
acquisition of control of rail common carriers. The outcome of STB proceedings can affect the profitability of BNSF Railway’s
business.
The DOT, OSHA and EPA have jurisdiction under several federal statutes over a number of safety, health, andenvironmental aspects of rail operations, including the transportation of hazardous materials. BNSF Railway is required totransport these materials to the extent of its common carrier obligation. State agencies regulate some health, safety, andenvironmental aspects of rail operations in areas not otherwise preempted by federal law.
Environmental Matters
BNSF’s rail operations, as well as those of its competitors, are also subject to extensive federal, state and local
environmental regulations covering discharges to the ground or waters, air emissions, toxic substances and the generation,
handling, storage, transportation and disposal of waste and hazardous materials. Such regulations effectively increase the costs
and liabilities associated with rail operations. Environmental risks are also inherent in rail operations, which frequently involve
transporting chemicals and other hazardous materials.
Many of BNSF’s land holdings are or have been used for industrial or transportation-related purposes or leased tocommercial or industrial companies whose activities may have resulted in discharges onto the property. Under federal statutes(in particular, the Comprehensive Environmental Response, Compensation and Liability Act) and state statutes, BNSF may beheld jointly and severally liable for cleanup and enforcement costs associated with a particular site without regard to fault or
the legality of the original conduct. BNSF may also be subject to claims by third parties for investigation, cleanup, restorationor other environmental costs under environmental statutes or common law with respect to properties they own that have been
impacted by BNSF operations.
Consumption of diesel fuel by locomotives accounted for approximately 80% of BNSF Railway’s greenhouse gas(“GHG”) emissions in its baseline year of 2018. BNSF management has committed to a broad sustainability model, applying
science based approaches, that will provide a 30% reduction in BNSF Railway’s GHG-emissions by 2030 from its baseline
year of 2018. BNSF Railway intends to continue improvements in fuel efficiency and increased utilization of renewable diesel
fuel. Long-term solutions, such as battery-electric and hydrogen locomotives, are also being evaluated and field-tested.
Competition
The business environment in which BNSF Railway operates is highly competitive. Depending on the specific market,
deregulated motor carriers and other railroads, as well as river barges, ships and pipelines, may exert pressure on price andservice levels. The presence of advanced, high service truck lines with expedited delivery, subsidized infrastructure andminimal empty mileage continues to affect the market for non-bulk, time-sensitive freight. The potential expansion of longer
combination vehicles could further encroach upon markets traditionally served by railroads. In order to remain competitive,
BNSF Railway and other railroads seek to develop and implement operating efficiencies to improve productivity.
As railroads streamline, rationalize and otherwise enhance their franchises, competition among rail carriers intensifies.
BNSF Railway’s primary rail competitor in the Western region of the U.S. is the Union Pacific Railroad Company. Other ClassI railroads and numerous regional railroads and motor carriers also operate in parts of the same territories served by BNSF
Railway.
Utilities and Energy Businesses
Berkshire’s energy businesses include a 92% ownership interest in Berkshire Hathaway Energy Company (“BHE”),
based in Des Moines, Iowa. In 2017, Berkshire acquired a 38.6% interest in Pilot Travel Centers, LLC (“PTC”), which isheadquartered in Knoxville, Tennessee. Through January 31, 2023, the investment in PTC was accounted for using the equity
method. On January 31, 2023, Berkshire acquired an additional 41.4% interest and attained control of PTC for financial
reporting purposes. PTC became a subsidiary in Berkshire’s Consolidated Financial Statements beginning February 1, 2023.
On January 16, 2024, Berkshire acquired an additional 20% interest in PTC and as of that date PTC became an indirect whollyowned Berkshire subsidiary. PTC’s business activities are primarily associated with fuel distribution and energy products andservices.

also own interests in independent power projects having approximately 5,900 net megawatts of generation capacity that are inservice in California, Texas, Illinois, Nebraska, Montana, Australia, New York, Arizona, Canada, Minnesota, Kansas, Iowa
and Hawaii. These independent power projects sell power generated primarily from wind, solar, geothermal and hydro sources
under long-term contracts. Additionally, BHE subsidiaries and other Berkshire subsidiaries have invested approximately $7.3
billion to-date in wind projects sponsored by third parties, commonly referred to as tax equity investments.
Regulatory Matters
The U.S. utilities are subject to comprehensive regulation by various federal, state and local agencies. The Federal Energy
Regulatory Commission (“FERC”) is an independent agency with broad authority to implement provisions of the Federal
Power Act, the Energy Policy Act of 2005 and other federal statutes. The FERC regulates rates for wholesale sales of electricity;transmission of electricity, including pricing and regional planning for the expansion of transmission systems; electric system
reliability; utility holding companies; accounting and records retention; securities issuances; construction and operation ofhydroelectric facilities; and other matters. The FERC also has the enforcement authority to assess civil penalties of up to $1.5
million per day per violation of rules, regulations and orders issued under the Federal Power Act. MEC is also subject toregulation by the Nuclear Regulatory Commission pursuant to the Atomic Energy Act of 1954, as amended, with respect to its
25% ownership of the Quad Cities Nuclear Station.
With certain limited exceptions, the U.S. utilities have an exclusive right to serve retail customers within their service
territories and, in turn, have an obligation to provide service to those customers. In some jurisdictions, certain classes ofcustomers may choose to purchase all or a portion of their energy from alternative energy suppliers, and in some jurisdictions
retail customers can generate all or a portion of their own energy. Historically, state regulatory commissions have establishedretail electric and natural gas rates on a cost-of-service basis, which are designed to allow a utility the opportunity to recoverwhat each state regulatory commission deems to be the utility’s reasonable costs of providing services, including theopportunity to earn a fair and reasonable return on its investments based on its cost of debt and equity. The retail electric ratesof U.S. utilities are generally based on the cost of providing traditional bundled services, including generation, transmission
and distribution services; however, rates are available for transmission-only and distribution-only services.
Northern Powergrid (Northeast) plc and Northern Powergrid (Yorkshire) plc each charge fees for the use of theirdistribution systems that are controlled by a formula prescribed by the Gas and Electricity Markets Authority, the British
electricity regulatory body. The current electricity distribution price control runs from April 1, 2023 through March 31, 2028.
AltaLink is regulated by the Alberta Utilities Commission (“AUC”), pursuant to the Electric Utilities Act (Alberta), thePublic Utilities Act (Alberta), the Alberta Utilities Commission Act (Alberta) and the Hydro and Electric Energy Act (Alberta).
The AUC is an independent quasi-judicial agency, which regulates and oversees Alberta’s electricity transmission sector withbroad authority that may impact many of AltaLink’s activities, including its tariffs, rates, construction, operations andfinancing. Under the Electric Utilities Act, AltaLink prepares and files applications with the AUC for approval of tariffs to be
paid by the Alberta Electric System Operator (“AESO”) for the use of its transmission facilities, and the terms and conditions
governing the use of those facilities. The AESO is an independent system operator in Alberta, Canada that oversees Alberta’s
integrated electrical system (“AIES”) and wholesale electricity market. The AESO is responsible for directing the safe, reliable
and economic operation of the AIES, including long-term transmission system planning.
The natural gas pipelines are subject to regulation by various federal and state agencies. The natural gas pipeline andstorage operations of BHE GT&S, Northern Natural and Kern River are regulated by the FERC pursuant to the Natural Gas
Act and the Natural Gas Policy Act of 1978. Under this authority, the FERC regulates, among other items, (a) rates, charges,
terms and conditions of service; (b) the construction and operation of interstate pipelines, storage and related facilities, including
the extension, expansion or abandonment of such facilities; and (c) the construction and operation of liquefied natural gas
export/import facilities. Interstate natural gas pipeline companies are also subject to regulations administered by the Office ofPipeline Safety within the Pipeline and Hazardous Materials Safety Administration, an agency of the DOT. Federal pipeline
safety regulations are issued pursuant to the Natural Gas Pipeline Safety Act of 1968, as amended, which establishes safety
requirements in the design, construction, operation and maintenance of interstate natural gas pipeline facilities.

Environmental Matters
BHE and its energy businesses are subject to federal, state, local and foreign laws and regulations regarding air quality,
climate change, emissions performance standards, water quality, coal ash disposal and other environmental matters that havethe potential to impact current and future operations. In addition to imposing continuing compliance obligations, these laws
and regulations, such as the Federal Clean Air Act, provide regulators with the authority to levy substantial penalties fornoncompliance, including fines, injunctive relief and other sanctions.
The Federal Clean Air Act, as well as state laws and regulations impacting air emissions, provides a framework forprotecting and improving the nation’s air quality and controlling sources of air emissions. These laws and regulations continue
to be promulgated and implemented and will impact the operation of BHE’s generating facilities and require them to reduce
emissions at those facilities to comply with the requirements. In addition, the potential adoption of state or federal clean energy
standards, which include low-carbon, non-carbon and renewable electricity generating resources, may also impact electricity
generators and natural gas providers.
In December 2015, an international agreement was negotiated by 195 nations to create a universal framework forcoordinated action on climate change in what is referred to as the Paris Agreement. The Paris Agreement reaffirms the goal of
limiting global temperature increase well below 2 degrees Celsius, while urging efforts to limit the increase to 1.5 degrees
Celsius and reaching a global peak of GHG emissions as soon as possible to achieve climate neutrality by mid-century;
establishes commitments by all parties to make nationally determined contributions and pursue domestic measures aimed atachieving the commitments; commits all countries to submit emissions inventories and report regularly on their emissions andprogress made in implementing and achieving their nationally determined commitments; and commits all countries to submit
new commitments every five years, with the expectation that the commitments will be more aggressive in reducing GHG
emissions. In the context of the Paris Agreement, the U.S. agreed to reduce GHG emissions by 26% to 28% from 2005 levels
by 2025. The Paris Agreement formally became effective on November 4, 2016; however, the U.S. completed its withdrawal
from the Paris Agreement on November 4, 2020. President Biden accepted the terms of the climate agreement on January 20,
2021, and the U.S. completed its reentry on February 19, 2021. New commitments to the Paris Agreement were announced in
April 2021, with the U.S. pledging to cut its overall GHG emissions by 50% to 52% from 2005 levels by 2030 and to reach
100% carbon pollution-free electricity by 2035. Increasingly, states are adopting legislation and regulations to reduce GHG
emissions, and local governments and consumers are seeking increasing amounts of clean and renewable energy.
On June 19, 2019, the EPA repealed the Clean Power Plan and issued the Affordable Clean Energy rule. In the Affordable
Clean Energy rule, the EPA determined that the best system of emissions reduction for existing coal fueled power plants is heatrate improvements and identified a set of candidate technologies and measures that could improve heat rates. Measures taken
to meet the standards of performance must be achieved at the source itself. On January 19, 2021, the D.C. Circuit Court ofAppeals vacated the Affordable Clean Energy rule in its entirety. In October 2021, the U.S. Supreme Court agreed to hear an
appeal of that decision. Arguments in the case were held in February 2022 and on June 30, 2022, the U.S. Supreme Court
issued its decision regarding the scope of the EPA’s authority to regulate GHG emissions under the Clean Air Act. The U.S.
Supreme Court held that the “generation shifting” approach in the Clean Power Plan exceeded the powers granted to the EPA
by Congress, although the court did not address whether the EPA may only adopt measures applied at the individual source as
it did in the Affordable Clean Energy rule. In May 2023, the EPA proposed new rules addressing GHG emissions for the power
sector. The proposed requirements would take effect January 1, 2030. The EPA subcategorized the best system of emissions
reduction based on fuel type. For existing coal, the EPA determined that the best system of emissions reduction is carbon
capture and sequestration. For existing natural gas-fueled steam units, the EPA determined that the best system of emissions
reduction is an emissions limit between 1,300 and 1,500 pounds of carbon dioxide per gross megawatt hour. For existing natural
gas combustion turbines, the EPA determined the best system of emissions reduction applies only to large, high-load turbines,
which must either use carbon capture and sequestration or a co-fueling with hydrogen. Finally, for new natural gas combustion
turbines, the EPA determined that the best system of emissions reduction is a co-fueling with hydrogen between 30% and 96%
blend rates by 2038. The EPA intends to finalize the rule by May 2024.
In November 2021, the EPA proposed rules that would reduce methane emissions from both new and existing sourcesin the oil and natural gas industry. The proposals would expand and strengthen emission reduction requirements for new,modified and reconstructed oil and natural gas sources and would require states to reduce methane emissions from existingsources nationwide. The EPA issued a supplemental proposal in November 2022 to further strengthen emission requirements.
The rule was finalized in December 2023. Affected sources may have up to five years from the rule’s effective date to comply
with requirements identified in state implementation plans.
BHE and its energy subsidiaries continue to focus on delivering reliable, affordable, safe and clean energy to its
customers and on actions to mitigate its GHG emissions. BHE’s primary source of GHG emissions is the generation ofelectricity from its power plants that are fueled by coal or natural gas. In managing its electricity generation, BHE works with
its regulators to protect the energy and economic needs of customers by considering costs, reliability and sources of electric
generation. Over the years, BHE has invested heavily in owned renewable generation and storage, with cumulative investments
K-10

of $34.1 billion through 2023 and has ceased coal operations at 18 coal generation units. As a result, as of December 31, 2023,
BHE reduced its annual GHG emissions by more than 34% as compared to 2005 levels. BHE plans to continue investing in
renewable and other low-carbon generation and storage in the future and to cease coal operations at an additional 15 coal
generation units between 2025 and 2030 in a reliable and cost-effective manner, thereby achieving a 50% reduction in GHG
emissions from 2005 levels in 2030.

Industrial products
Precision Castparts
Precision Castparts Corp. (“PCC”), based in Lake Oswego, Oregon, manufactures complex metal components andproducts, provides high-quality investment castings, forgings, fasteners/fastener systems and aerostructures for criticalaerospace and power and energy applications. PCC also manufactures investment castings and forgings for general industrial,
armament, medical and other applications; nickel and titanium alloys in all standard mill forms from large ingots and billets toplate, foil, sheet, strip, tubing, bar, rod, extruded shapes, rod-in-coil, wire and welding consumables, as well as cobalt alloys,
for the aerospace, chemical processing, oil and gas, pollution control and other industries; fasteners for automotive and generalindustrial markets; specialty alloys for the investment casting and forging industries; heat treating and destructive testing
services for the investment cast products and forging industries; grinder pumps and affiliated components for low-pressure
sewer systems; critical auxiliary equipment and gas monitoring systems for the power generation industry; and metalworking
tools for the fastener market and other applications.
Investment casting technology involves a multi-step process that uses ceramic molds in the manufacture of metalcomponents with more complex shapes, closer tolerances and finer surface finishes than parts manufactured using othermethods. PCC uses this process to manufacture products for aircraft engines, industrial gas turbine and other aeroderivativeengines, airframes, medical implants, armament, unmanned aerial vehicles and other industrial applications. PCC also
manufactures high temperature carbon and ceramic composite components, including ceramic matrix composites, for use innext-generation aerospace engines.
PCC uses forging processes to manufacture components for the aerospace and power generation markets. PCC
manufactures high-performance, nickel-based alloys, as well as titanium alloys and products. PCC’s nickel-based alloys areused to produce forged components and investment castings for aerospace and non-aerospace applications in such markets as
oil and gas, chemical processing and pollution control. PCC’s titanium products are used to manufacture components for thecommercial and military aerospace, power generation, energy, medical, and industrial end markets.
PCC is also a leading developer and manufacturer of highly engineered fasteners, fastener systems, aerostructures andprecision components, primarily for critical aerospace applications. These products are produced for the aerospace and powerand energy markets, as well as for construction, automotive, heavy truck, farm machinery, mining and construction equipment,
shipbuilding, machine tools, medical equipment, appliances and recreation markets.
PCC has several significant customers, including aerospace original equipment manufacturers (“OEMs”) (Boeing andAirbus) and aircraft engine manufacturer suppliers (General Electric, Rolls Royce and Pratt &Whitney). The majority of PCC’ssales are from customer orders or demand schedules pursuant to long-term agreements. Contractual terms may provide fortermination by the customer, subject to payment for work performed. PCC typically does not experience significant ordercancellations, although periodically it receives requests for delays in delivery schedules.
The global outbreak of COVID-19 which began in March 2020 drove unprecedented build rate reductions and destocking
in the aerospace market through 2021. In 2022, PCC began to see recovery in the domestic markets, with international travel
starting to improve in the latter part of 2022. Domestic travel has surpassed 2019 levels, while international travel remains justbelow 2019 levels. Long-term industry forecasts continue to show growth and strong demand for air travel and aerospace
products.
PCC is subject to substantial competition in all of its markets. Components and similar products may be produced bycompetitors, who use either the same types of manufacturing processes as PCC or other processes. Although PCC believes its
manufacturing processes, technology and experience provide its customers advantages, such as high quality, competitive prices
and physical properties that often meet more stringent demands, alternative forms of manufacturing can be used to produce
many of the same components and products. Nevertheless, PCC is a leading supplier in most of its principal markets. Several
factors, including long-standing customer relationships, technical expertise, state-of-the-art facilities and dedicated employees,
aid PCC in maintaining competitive advantages.
Several raw materials used in PCC products, including certain metals such as nickel, titanium, cobalt, tantalum, hafnium
and molybdenum, are found in only a few parts of the world. These metals are required for the alloys used in manufactured
products. The availability and costs of these metals may be influenced by private or governmental cartels, changes in worldpolitics, labor relations between the metal producers and their workforces and inflation.

K-12

PCC is currently subject to various federal, state and foreign environmental laws concerning, among other things, water
discharges, air emissions, waste management, toxic materials use reduction and environmental cleanup. Laws and regulations
continue to evolve, and it is reasonably possible that environmental standards will become more stringent in the future,
particularly under air quality and water quality laws and standards related to climate change, including reporting of GHG
emissions. As a result, it is also reasonably likely that PCC will be regularly required to make additional expenditures, including
capital expenditures, which could be significant, relating to environmental matters.

Building Products
ClaytonClayton Homes, Inc. (“Clayton”), headquartered near Knoxville, Tennessee, is a vertically integrated housing company
offering traditional site-built homes and off-site (factory) built housing, including modular, manufactured, CrossMod™ andtiny homes. In 2023, Clayton delivered approximately 43,000 off-site built and approximately 10,000 site-built homes. Clayton
also offers home financing and other financial services and competes on price, service, location and delivery capabilities.
All Clayton Built® off-site built homes are designed, engineered and assembled in the U.S. As of December 2023, offsite backlog was $799 million, up over 200% from the prior year end. Clayton sells off-site built homes through independentand company-owned home centers, realtors and subdivision channels. Clayton considers its ability to offer financing to retailpurchasers a factor affecting the marketplace acceptance of its off-site built homes. Clayton’s financing programs utilize
proprietary loan underwriting guidelines to evaluate loan applicants.
Since 2015, Clayton’s site-built division, Clayton Properties Group, has expanded through the acquisition of ninebuilders across 18 states with over 290 subdivisions, supplementing the portfolio of housing products offered to customers.
Clayton’s site-builders currently own and control approximately 67,000 homesites, with a home order backlog of approximately$1.6 billion as of December 2023.
Historically, access to key housing inputs such as lumber, steel and resin products has been adequate. During 2021 andthe first half of 2022, the availability and pricing of these and other inputs was volatile. Input shortages coupled with reduced
labor and subcontractor availability increased the time needed to construct a home, increasing the levels of work-in-process
inventory. These constraints began to lessen in the latter half of 2022 due to improved availability and pricing of key inputs,
increased order cancellations and lower overall demand for new home construction.
Clayton’s building products business benefited in recent years from the low interest rate environment and the strong
residential construction market. However, the effects of significant increases in home mortgage interest rates in the U.S. overthe past year has slowed demand for new home construction, partially mitigated by low supplies of pre-existing homes for sale.
Clayton’s home building business regularly makes capital and non-capital expenditures with respect to compliance withfederal, state and local environmental regulations, primarily related to erosion control, permitting and stormwater protection
for site-built home subdivisions. The financing business originates and services loans which are federally regulated by theConsumer Financial Protection Bureau, various state regulatory agencies and reviewed by the U.S. Department of Housing and
Urban Development, the Government National Mortgage Association and government-sponsored enterprises.

Substantially all carpet manufactured by Shaw is tufted carpet made from nylon, polypropylene and polyester, as well as
recycled materials. During 2023, Shaw processed approximately 93% of its requirements for carpet yarn in its own yarnprocessing facilities. The availability of raw materials is adequate, but costs are impacted by petro-chemical and natural gas
price changes. A significant portion of Shaw’s soft-flooring raw materials derive from recycled sources. Raw material costchanges are periodically factored into selling prices to customers.
The soft floor covering industry is highly competitive with only a handful of major competitors domestically. There are
numerous manufacturers, domestically and internationally, that are engaged in the hard surfaces flooring sector. According toindustry estimates, carpet accounts for approximately 39% of the total U.S. consumption of all flooring types. The principal
competitive measures within the floor covering industry are quality, style, price and service.

108 new vehicle franchises through 83 dealerships located primarily in major metropolitan markets in the U.S. The dealerships

and other aftermarket products. BHA also arranges financing for its customers through third-party lenders. BHA operates 31
collision centers directly connected to the dealerships’ operations and owns and operates two auto auctions and an automotive
fluid maintenance products distributor.
Dealership operations are highly concentrated in the Arizona and Texas markets, with approximately 75% of dealershiprelated revenues derived from sales in these markets. BHA currently maintains franchise agreements with 27 different vehicle
manufacturers, although it derives a significant portion of its revenue from the Toyota/Lexus, General Motors, Ford/Lincoln,
Nissan/Infiniti and Honda/Acura brands. These manufacturers represent approximately 90% of the revenue generated by
BHA’s dealerships.
The retail automotive industry is highly competitive. BHA faces competition from other large public and private
dealership groups, as well as individual franchised dealerships and competition via the Internet. Given the retail pricetransparency available via the Internet, and the fact that franchised dealers acquire vehicles from the manufacturers on the sameterms irrespective of volume, the location and quality of the dealership facility, customer service and transaction speed are key
differentiators in attracting customers.

K-22

dealerships. Failure to meet the terms of these agreements could adversely impact BHA’s ability to acquire additional
dealerships representing those manufacturers. Additionally, these agreements contain limitations on the number of dealerships
from a specific manufacturer that may be owned by BHA.

area, as well as the right to use the manufacturer’s trademarks. The agreements contain various requirements and restrictions
related to the management and operation of the franchised dealership and provide for termination of the agreement by the
manufacturer or non-renewal for a variety of causes. States generally have automotive dealership franchise laws that provide
substantial protection to the franchisee, and it is difficult for a manufacturer to terminate or not renew a franchise agreement
outside of bankruptcy or with “good cause” under the applicable state franchise law.

Item 1A. Risk Factors
Berkshire and its subsidiaries (referred to herein as “we,” “us,” “our” or similar expressions) are subject to certain risks
and uncertainties in its business operations which are described below. The risks and uncertainties described below are not the
only risks we face. Additional risks and uncertainties that are presently unknown or are currently deemed immaterial may also
impair our business operations.
General Business Risks
Terrorist acts could hurt our operating businesses.
A nuclear, biological or chemical terrorist attack or armed terrorist incursions could produce significant losses to ourworldwide operations. Our business operations could be adversely affected from such acts through the loss of human life,
destruction of production facilities and information systems or other property damage. We share these risks with all businesses.
Cybersecurity risks.
We rely on technology in virtually all aspects of our business. Like those of many large businesses, certain of our
information systems have been subject to computer viruses, malicious codes, unauthorized access, phishing efforts, denial-ofservice attacks and other cyber-attacks. We expect to be subject to similar attacks in the future as such attacks become moresophisticated and frequent. A significant disruption or failure of our technology systems could result in service interruptions,safety failures, security events, regulatory compliance failures, an inability to protect information and assets against
unauthorized users and other operational difficulties. Attacks perpetrated against our systems could result in loss of assets andcritical information and expose us to remediation costs and reputational damage.
Although we have taken steps intended to mitigate these risks, including business continuity planning, disaster recovery
planning and business impact analysis, a significant disruption or cyber intrusion at one or more of our significant operations
could adversely affect our results of operations, financial condition and/or liquidity. Additionally, if we are unable to acquire,develop, implement, adopt or protect rights around new technology, we may suffer a competitive disadvantage, which could
also have an adverse effect on our results of operations, financial condition and/or liquidity.
Cyber-attacks could further adversely affect our ability to operate facilities, information technology and business systems
or compromise confidential customer and employee information. Political, economic, social or financial market instability or
damage to or interference with our operating assets, customers or suppliers from cyber-attacks may result in businessinterruptions, lost revenues, higher commodity prices, disruption in fuel supplies, lower energy consumption, unstable markets,
increased security, repair or other costs, or may materially adversely affect us in ways that cannot be predicted at this time.
Any of these risks could materially affect our consolidated financial results. Furthermore, instability in the financial markets
resulting from terrorism, sustained or significant cyber-attacks or war could also have a material adverse effect on our ability
to raise capital. We share these risks with all businesses.
Geopolitical events could cause losses to our business and losses in the values of securities we own.
We believe risks of adverse effects from geopolitical events are rising, through armed and diplomatic conflicts involving
governments in various parts of the world. Government policies and actions taken, including responses of other governments
to such actions, may adversely affect our operating businesses through reduced sales, increased costs, restricted supply chains,
physical damage to our properties and loss of life of our employees. We share these risks with all businesses.
We are dependent on a few key people for our major investment and capital allocation decisions.
Major investment decisions and all major capital allocation decisions are made by Warren E. Buffett, Chairman of theBoard of Directors and Chief Executive Officer, age 93. In 2018, Berkshire’s Board of Directors appointed Mr. Gregory Abelas Vice Chairman of Berkshire’s non-insurance operations and Mr. Ajit Jain as Vice Chairman of Berkshire’s insurance
operations. Mr. Abel and Mr. Jain each report directly to Mr. Buffett. Mr. Buffett continues to be responsible for major capital
allocation and investment decisions.
If for any reason the services of our key personnel, particularly Mr. Buffett, were to become unavailable, there could bea material adverse effect on our operations. Should a replacement for Mr. Buffett be needed currently, Berkshire’s Board of
Directors has agreed that Mr. Abel should replace Mr. Buffett. The Board continually monitors this risk and could alter its
current view regarding a replacement for Mr. Buffett in the future. We believe that the Board’s succession plan, together withthe outstanding managers running our numerous and highly diversified operating units, helps to mitigate this risk.

K-25

We need qualified personnel to manage and operate our various businesses.
In our decentralized business model, we need qualified and competent management to direct day-to-day businessactivities of our operating subsidiaries and to manage changes in future business operations due to changing business orregulatory environments. Our operating subsidiaries also need qualified and competent personnel to execute business plans andserve their customers, suppliers and other stakeholders. Our inability to recruit, train and retain qualified and competentmanagers and personnel could negatively affect the operating results, financial condition and/or liquidity of our subsidiaries
and Berkshire as a whole.
Investments are unusually concentrated in equity securities and fair values are subject to loss in value.
We concentrate a high percentage of the equity security investments of our insurance subsidiaries in a relatively small
number of issuers. A significant decline in the fair values of our larger investments in equity securities may produce a material
decline in our consolidated shareholders’ equity and our consolidated earnings.
Since a large percentage of our equity securities are held by our insurance subsidiaries, significant decreases in the fairvalues of these investments will produce significant declines in the statutory surplus of our insurance subsidiaries. Our large
statutory surplus is a competitive advantage, and a long-term material decline could have an adverse effect on our claimspaying ability ratings and our ability to write new insurance business thus potentially reducing our future underwriting profits.
Competition and technology may erode our business franchises and result in lower earnings.
Each of our operating businesses face intense competition within markets in which they operate. While we manage ourbusinesses with the objective of achieving long-term sustainable growth by developing and strengthening competitive
advantages, many factors, including technological changes, may erode or prevent the strengthening of competitive advantages.
Accordingly, our future operating results will depend to some degree on our operating units successfully protecting andenhancing their competitive advantages. If our operating businesses are unsuccessful in these efforts, our periodic operating
results in the future may decline.
Unfavorable general economic conditions may significantly reduce our operating earnings and impair our ability toaccess capital markets at a reasonable cost.
Our operating businesses are subject to normal economic cycles affecting the general economy or the specific industries
in which they operate. Significant deteriorations of economic conditions, including significant inflation over a prolonged period
could produce a material adverse effect on one or more of our significant operations. In addition, our utilities and energy
businesses and our railroad business regularly utilize debt as a component of their capital structures and depend on having
access to borrowed funds through the capital markets at reasonable rates. To the extent that access to the capital markets is
restricted or the cost of funding increases, these operations could be adversely affected.
Epidemics, pandemics or other similar outbreaks could hurt our operating businesses.
The outbreak of epidemics, pandemics or other similar outbreaks in the future may adversely affect our operations,
including the value of our equity securities portfolio. This may be due to closures or restrictions requested or mandated bygovernmental authorities, disruption to supply chains and workforce, reduction of demand for our products and services, credit
losses when customers and other counterparties fail to satisfy their obligations to us, and volatility in global equity securities
markets, among other factors. We share most of these risks with all businesses.
Regulatory changes may adversely impact our future operating results.
Over time, in response to financial markets crises, global economic recessions, and social and environmental issues,
regulatory initiatives were adopted in the United States and elsewhere. Such initiatives addressed, for example, the regulationof banks and other major financial institutions, the regulation of products and environmental and global-warming matters.
These initiatives impact all of our businesses, albeit in varying ways. Increased regulatory compliance costs could have asignificant negative impact on our operating businesses, as well as on the businesses in which we have significant, but notcontrolling, economic interests. We cannot predict whether such initiatives will have a material adverse impact on ourconsolidated financial position, results of operations and/or cash flows.
Data privacy regulations have recently been enacted in various jurisdictions in the U.S. and throughout the world. These
regulations address numerous aspects related to the security of personal information that is stored in our information systems,
networks and facilities. Failure to comply with these regulations could result in reputational damage and significant economic
penalties.

K-26

Climate change and the regulation of greenhouse gas (“GHG”) emissions may impact our businesses.
The impacts of climate change and the regulation of GHG emissions could impact our businesses to varying degrees.
Climate change could cause or intensify hurricanes, floods, wildfires, and other extreme weather events that may increase thephysical risks to and impacts on our operations. An increase in the frequency or intensity of extreme weather events and storms
could impact the physical assets of our non-insurance operations and could produce losses affecting our businesses. Similarly,
extreme weather events may produce losses affecting our insurance operations as their primary business is to monitor, assess
and price risk, including climate-related risk, at an expected economic profit to address the risk-transfer needs of their insurance
customers.
Additional GHG policies, including legislation, may emerge that accelerate the transition to a lower-GHG emitting
economy and could, in turn, increase costs for our businesses to comply with those policies, including BNSF and BHE, which
combined represent more than 90% of Berkshire’s direct emissions. The failure to comply with new or existing regulations orreinterpretation of existing regulations relating to climate change could have a significant adverse effect on our financial results.
Risks unique to our regulated businesses
Our tolerance for underwriting risk in our various insurance businesses may result in significant underwriting losses.
When properly paid for the risk assumed, we have been and will continue to be willing to assume more risk from a single
event than any other insurer has knowingly assumed. Accordingly, we could incur a significant loss from a single catastrophe
event resulting from a natural disaster or man-made catastrophes such as terrorism or cyber-attacks. We employ various
disciplined underwriting practices intended to mitigate potential losses, attempt to take into account all possible correlations
and avoid writing groups of policies from which pre-tax losses from a single catastrophe event might aggregate in excess of$15 billion. However, despite our efforts, it is possible that losses could manifest in ways that we do not anticipate and that ourrisk mitigation strategies are not designed to address. Various provisions of our policies, negotiated to limit our risk, such as
limitations or exclusions from coverage, may not be enforceable in the manner we intend, as it is possible that a court or
regulatory authority could nullify or void an exclusion or limitation, or legislation could be enacted modifying or barring theuse of these exclusions and limitations. Our tolerance for significant insurance losses may result in lower reported earnings in
a future period.
The principal cost associated with the property and casualty insurance business is claims. In writing property and casualty
insurance policies, we receive premiums today and promise to pay covered losses in the future. However, it will take decades
before all claims that have occurred as of any given balance sheet date will be reported and settled. Although we believe thatrecorded liabilities for unpaid losses are adequate, we will not know whether these liabilities or the premiums charged for thecoverages provided were sufficient until well after the balance sheet date. Estimating insurance claim costs is inherently
imprecise. It is possible that significant claims may emerge or develop in the future from the policies we have written in thepast. As industry practices and legal, social and other environmental conditions change, unexpected and unintended issues
related to claims and coverage may emerge, including new or expanded theories of liability. These or other changes could
impose new financial obligations on us by extending coverage beyond our underwriting intent. In some instances, these changes
may not become apparent until sometime after we have issued insurance or reinsurance contracts that are affected by thechanges. As a result, the full extent of liability under our insurance or reinsurance contracts may not be known for many years
after a contract is issued. Our estimated unpaid losses arising under contracts covering property and casualty insurance risks
are large ($146 billion at December 31, 2023), and a small percentage increase to those liabilities can result in materially lower
reported earnings.
Changes in regulations and regulatory actions can adversely affect our operating results and our ability to allocate
capital.
Our insurance businesses are subject to regulation in the jurisdictions in which we operate. Such regulations may relate
to, among other things, the types of business that can be written, the rates that can be charged for coverage, the level of capitalthat must be maintained and restrictions on the types and size of investments that can be made. Regulations may also restrict
the timing and amount of dividend payments to Berkshire by these businesses. U.S. state insurance regulators and international
insurance regulators are also actively developing various regulatory mechanisms to address the regulation of large
internationally active insurance groups, including regulations concerning group capital, liquidity, governance and risk
management. Accordingly, changes in regulations related to these or other matters or regulatory actions imposing restrictions
on our insurance businesses may adversely impact our results of operations and restrict our ability to allocate capital.

K-27

Our railroad business conducted through BNSF is also subject to a significant number of laws and regulations withrespect to rates and practices, taxes, railroad operations and a variety of health, safety, labor, environmental and other matters.
Failure to comply with applicable laws and regulations could have a material adverse effect on BNSF’s business. Governments
may change the legislative and/or regulatory framework within which BNSF operates, without providing any recourse for any
adverse effects that the change may have on the business. Complying with legislative and regulatory changes may posesignificant operating and implementation risks and require significant capital expenditures.
BNSF derives significant amounts of revenue from the transportation of energy-related commodities, particularly coal.
To the extent that changes in government policies limit or restrict the usage of coal as a fuel source in generating electricity oralternate fuels, such as natural gas, or otherwise displace coal as an energy source, revenues and earnings could be adversely
affected. As a common carrier, BNSF is also required to transport toxic inhalation hazard chemicals and other hazardous
materials. A release of hazardous materials could expose BNSF to significant claims, losses, penalties and environmental
remediation obligations. Changes in the regulation of the rail industry could negatively impact BNSF’s ability to determine
prices for rail services and to make capital improvements to its rail network, resulting in an adverse effect on our results ofoperations, financial condition and/or liquidity.
Our utilities and energy businesses operated under BHE are highly regulated by numerous federal, state, local and foreign
governmental authorities in the jurisdictions in which they operate. These laws and regulations are complex, dynamic andsubject to new interpretations or change. Regulations affect almost every aspect of our utilities and energy businesses.
Regulations broadly apply and may limit management’s ability to independently make and implement decisions regarding
numerous matters including: acquiring businesses; constructing, acquiring, disposing or retiring of operating assets; operating
and maintaining generating facilities and transmission and distribution system assets; complying with pipeline safety andintegrity and environmental requirements; setting rates charged to customers; establishing capital structures and issuing debt;
managing and reporting transactions between our domestic utilities and our other subsidiaries and affiliates; and paying
dividends or similar distributions. Failure to comply with or reinterpretations of existing regulations and new legislation or
regulations, such as those relating to air quality, climate change, emissions performance standards, water quality, coal ash
disposal and other environmental matters, or changes in the nature of the regulatory process may have a significant adverse
impact on our financial results.
Our railroad business requires significant ongoing capital investment to improve and maintain its railroad network sothat transportation services can be safely and reliably provided to customers on a timely basis. Our utilities and energy
businesses also require significant amounts of capital to construct, operate and maintain generation, transmission anddistribution systems to meet their customers’ needs and reliability criteria. System assets may need to be operational for long
periods of time to justify the financial investment. The operational or financial failure of capital projects may not be recoverable
through rates that are charged to customers. Further, a significant portion of costs of capital improvements may be fundedthrough debt issued by BNSF and BHE and their subsidiaries. Disruptions in debt capital markets that restrict access to funding
when needed could adversely affect the results of operations, liquidity and/or capital resources of these businesses.
Item 1B. Unresolved Staff Comments
None.
Item 1C. Cybersecurity
Berkshire recognizes that maintaining processes for identifying, assessing, and managing cybersecurity threats isimportant in dealing with its significant business risks. As such, Berkshire has implemented a framework for cybersecurity andcyber-related information management across Berkshire’s diverse groups of businesses. The framework permits each Berkshire
Business Group (“Business Group”) to tailor solutions to identify, manage, and mitigate risks based on their own assessmentof their unique cybersecurity risks in conjunction with each Business Group’s overall risk management processes. At the sametime, the framework helps enable consistent and appropriate compliance in reporting material cyber events and risks acrossBerkshire.
Each Business Group’s Chief Information Security Officer (“CISO”) on at least an annual basis is to provide a report to
the Business Group’s senior management, regarding the state of their cybersecurity program and its material cyber risks. These
reports are also shared with Berkshire’s internal audit group to inform and enhance the overall company’s risk management
processes. In addition, each Business Group is required to maintain an incident reporting process to report significant
cybersecurity events to Berkshire. Berkshire and its Business Groups engage and partner with a wide range of third parties toassess, audit, educate, implement, operate, protect, and remediate various cybersecurity related elements.

K-28

Berkshire and its Business Groups rely on third-party service providers for a variety of products and services to run theirinformation systems. This dependence exposes us, along with others who use these service providers, to the impact of a cyberattack on their service providers. On occasion, a cyber-attack at a third party service provider could have a significant financial,
operational or reputational impact to Berkshire. Berkshire and its Business Groups continuously monitor the risks associatedwith its service providers.
The Audit Committee of Berkshire’s Board of Directors has responsibility for oversight of Berkshire’s cybersecurity risk
management program. The Audit Committee receives periodic reports regarding the number of and impact from cybersecurity
incidents reported through Berkshire’s cybersecurity incident reporting process. Additionally, the Audit Committee is updated
on cybersecurity trends and common deficiencies. Furthermore, the Audit Committee approves and receives updates on theworkplan performed by Berkshire’s internal audit group that focuses on information technology and cybersecurity risks. This
includes audit procedures related to internal and external penetration testing, attack simulations, vulnerability assessments,
cybersecurity program reviews and other audits designed to investigate specific risks. The frequency of these updates isdetermined by the Audit Committee in conjunction with Berkshire’s senior management.
In addition to the Audit Committee’s oversight, the senior management of Berkshire’s Businesses Groups are responsible
for the day-to-day operations of protecting their businesses’ information systems. Each Business Group is required to reportsignificant cybersecurity events to Berkshire. Berkshire’s senior management reviews incident reports to determine whether acyber incident report should be filed with the SEC.

Item 3. Legal Proceedings
Berkshire and its subsidiaries are parties in a variety of legal actions that routinely arise out of the normal course ofbusiness, including legal actions seeking to establish liability directly through insurance contracts or indirectly throughreinsurance contracts issued by Berkshire subsidiaries. Plaintiffs occasionally seek punitive or exemplary damages. We do notbelieve that such normal and routine litigation will have a material effect on our financial condition or results of operations.
Reference is made to Note 27 to the accompanying Consolidated Financial Statements for information concerning certain
litigation involving Berkshire subsidiaries. Berkshire and certain of its subsidiaries are also involved in other kinds of legal
actions, some of which assert or may assert claims or seek to impose fines and penalties. We currently believe that any liability
that may arise as a result of other pending legal actions will not have a material effect on our consolidated financial condition
or results of operations.

Through our subsidiaries, we engage in numerous diverse business activities. We manage our operating businesses onan unusually decentralized basis. There are few centralized or integrated business functions. Our senior corporate management
team participates in and is ultimately responsible for significant capital allocation decisions, investment activities and theselection of the Chief Executive to head each of the operating businesses. The business segment data (Note 26 to theaccompanying Consolidated Financial Statements) should be read in conjunction with this discussion.
To varying degrees, our operating businesses have been impacted by government and private sector actions taken to
mitigate the adverse economic effects of the COVID-19 virus and its variants, as well as by the development of global
geopolitical conflicts, supply chain disruptions and government actions to slow inflation. We cannot reliably predict the future
economic effects of these events on our businesses.
Insurance underwriting generated after-tax earnings of $5.4 billion in 2023, losses of $30 million in 2022 and earnings
of $870 million in 2021. Earnings in 2023 benefited from relatively low losses from significant catastrophe events during theyear and improved underwriting results at GEICO compared to 2022, reflecting the impacts of premium rate increases andlower claims frequencies. Underwriting results in 2022 and 2021 included after-tax losses from significant catastrophe eventsof approximately $2.4 billion and $2.3 billion, respectively. Underwriting losses in 2022 also reflected accelerating claims
costs at GEICO. Earnings from insurance underwriting increased $60 million in 2022 and $142 million in 2021 from amounts
previously reported due to the retrospective adoption of ASU 2018-12.
After-tax earnings from insurance investment income increased $3.1 billion (47.5%) in 2023 and $1.7 billion in 2022
(34.9%) compared to corresponding prior years. These increases were primarily attributable to higher short-term interest rates,
which resulted in significant increases in earnings from our short-term investments.
After-tax earnings of BNSF declined 14.4% in 2023 compared to 2022 and were relatively unchanged in 2022 compared
to 2021. The decrease in 2023 was primarily attributable to lower overall freight volumes and higher non-fuel operating costs,
partially offset by lower fuel costs. Results in 2022 reflected higher revenue per car/unit, substantially offset by lower overall
freight volumes and higher fuel and other operating costs compared to 2021.
After-tax earnings of our utilities and energy business declined 40.3% in 2023 compared to 2022 and increased 9.3% in2022 compared to 2021. The earnings decline in 2023 reflected lower earnings from the U.S. regulated utilities, reflecting
increased wildfire loss estimates, as well as lower earnings from other energy businesses and real estate brokerage businesses.
The increase in 2022 reflected higher earnings from other energy businesses, including tax equity investments and the Northern
Powergrid businesses, as well as from the natural gas pipeline businesses, partly offset by lower earnings from the real estate
brokerage business.
As disclosed in Note 2 to the accompanying Consolidated Financial Statements, we increased our ownership in PTC
from 38.6% to 80% on January 31, 2023 and we began consolidating PTC’s results of operations on February 1, 2023. In 2021
and 2022 and through January 31, 2023, earnings from PTC on our 38.6% interest were determined under the equity method
and are included in earnings from non-controlled businesses in the preceding table.

Management’s Discussion and Analysis
Results of Operations
Earnings from our manufacturing, service and retailing businesses increased 2.0% in 2023 compared to 2022 and 12.5%
in 2022 compared to 2021. Earnings in 2023 reflected increases at certain industrial products manufacturers and services
businesses and the impact of Alleghany’s non-insurance businesses acquired in 2022, partially offset by lower earnings fromseveral of our other manufacturing businesses, and from certain of our service and retailing businesses. Operating results in
2022 were mixed among our various businesses. While customer demand for products and services was relatively good in
2022, we experienced weakening demand in the second half of the year at certain of our businesses, which continued through2023.
Investment and derivative contract gains (losses) in each of the three years predominantly derived from our investmentsin equity securities and included significant net unrealized gains and losses from market price changes. We believe thatinvestment gains and losses on investments in equity securities, whether realized from dispositions or unrealized from changes
in market prices, are generally meaningless in understanding our reported periodic results or evaluating the economic
performance of our operating businesses. These gains and losses have caused and will continue to cause significant volatility
in our periodic earnings. Investment and derivative contract gains (losses) also included an after-tax non-cash remeasurement
gain of approximately $2.4 billion in the first quarter of 2023 related to our previously held 38.6% interest in PTC through theapplication of the acquisition accounting method.
Other earnings included after-tax foreign exchange rate gains of approximately $200 million in 2023, $1.3 billion in
2022 and $1.0 billion in 2021 related to the non-U.S. Dollar denominated debt issued by Berkshire and its U.S.-based financesubsidiary, Berkshire Hathaway Finance Corporation (“BHFC”).
Insurance—Underwriting
Our management views our insurance businesses as possessing two distinct activities – underwriting and investing.
Underwriting decisions are the responsibility of the unit managers, while investing decisions are the responsibility ofBerkshire’s Chairman and CEO, Warren E. Buffett and Berkshire’s corporate investment managers. Accordingly, we evaluate
performance of underwriting operations without any allocation of investment income or investment gains and losses. We
consider investment income as an integral component of our aggregate insurance operating results. However, we consider
investment gains and losses, whether realized or unrealized, as non-operating. We believe that such gains and losses are notmeaningful in understanding the periodic operating results of our insurance businesses.
The timing and magnitude of catastrophe losses can produce significant volatility in our periodic underwriting results,
particularly with respect to our reinsurance businesses. We currently consider pre-tax incurred losses exceeding $150 million
from a current year catastrophic event to be significant. Significant catastrophe events in 2023 were a cyclone and floods in
New Zealand and a hailstorm in Italy. In 2022, significant events were Hurricane Ian and floods in Australia, while significant
events in 2021 included Hurricane Ida, floods in Europe and Winter Storm Uri.
Changes in estimates for unpaid losses and loss adjustment expenses, including amounts established for occurrences inprior years, can also significantly affect our periodic underwriting results. Unpaid loss estimates, including estimates underretroactive reinsurance contracts, were approximately $146 billion as of December 31, 2023 and $143 billion as of December
31, 2022. Our periodic underwriting results may also include foreign currency transaction gains and losses arising from thechanges in the valuation of non-U.S. Dollar denominated liabilities of our U.S.-based subsidiaries due to foreign currency
exchange rate fluctuations.
We provide primary insurance and reinsurance products covering property and casualty risks, as well as life and healthrisks. Our insurance and reinsurance businesses are GEICO, Berkshire Hathaway Primary Group (“BH Primary”) and Berkshire
Hathaway Reinsurance Group (“BHRG”). Berkshire acquired Alleghany Corporation (“Alleghany”) on October 19, 2022.
Alleghany conducts property and casualty insurance businesses through RSUI Group Inc. and CapSpecialty, Inc. (“RSUI and
CapSpecialty” or “Alleghany Insurance”), and reinsurance businesses through Transatlantic Reinsurance Company andaffiliates (“TransRe Group”). Underwriting results of Alleghany Insurance are included in BH Primary and underwriting resultsof TransRe Group are included in BHRG.
We strive to produce pre-tax underwriting earnings (defined as premiums earned less insurance losses/benefits incurred
and underwriting expenses) over the long term in all business categories, except in BHRG’s retroactive reinsurance and periodic
payment annuity businesses. Time-value-of-money is an important element in establishing prices for retroactive reinsurance
and periodic payment annuity policies. We normally receive premiums at the contract inception date, which are then available
for investment. Ultimate claim payments can extend for decades and are expected to exceed premiums, producing underwriting
losses over the claim settlement periods, primarily through deferred charge asset amortization and liability discount accretion
charges.

GEICO’s pre-tax underwriting earnings in 2023 reflected higher average premiums per auto policy, lower claims
frequencies, reductions in prior accident years’ claims estimates and a reduction in advertising costs. However, average claims
severities continued to rise in 2023 due to higher auto repair parts prices, labor costs and medical inflation. Pre-tax underwriting
losses in 2022 reflected higher claims frequencies and significant increases in average claims severities, primarily due tosubstantial cost inflation, which began to accelerate in the second half of 2021 and continued through 2022. GEICO sought
rate increases in numerous states in 2022 and 2023 in response to accelerating claims costs. GEICO also significantly reduced
advertising expenditures in 2022 and 2023, which contributed to reductions of policies-in-force.
2023 versus 2022
Premiums written increased $730 million (1.9%) in 2023 compared to 2022, reflecting higher average premiums per auto
policy (16.8%) due to rate increases, partially offset by a 9.8% decrease in policies-in-force. Premiums earned increased $280
million (0.7%) in 2023 compared to 2022.
Losses and loss adjustment expenses decreased $4.5 billion (12.4%) in 2023 compared to 2022. GEICO’s loss ratio(losses and loss adjustment expenses to premiums earned) was 81.0% in 2023, a decrease of 12.1 percentage points compared
to 2022. The decline reflected the impact of higher average premiums per auto policy, lower claims frequencies and increased
favorable development of prior accident years’ claims estimates, partially offset by increases in average claims severities.

K-37

Management’s Discussion and Analysis
Insurance—Underwriting
GEICO (Continued)
Claims frequencies in 2023 were lower for property damage and collision coverages (seven to eight percent range), while
claims frequencies increased for bodily injury coverage (one to two percent range). Average claims severities in 2023 werehigher for all coverages, including property damage (fourteen to sixteen percent range), collision (four to six percent range)
and bodily injury (five to seven percent range). Losses and loss adjustment expenses included reductions in the ultimate loss
estimates for prior accident years’ claims of $1.5 billion in 2023 and $653 million in 2022. The reductions in each year wereacross several major coverages. In 2022, the reduction was partially offset by an increase in property damage prior years’
claims incurred.
Underwriting expenses declined $752 million (16.5%) in 2023 compared to 2022. GEICO’s expense ratio (underwriting
expense to premiums earned) was 9.7% in 2023, a decrease of 2.0 percentage points compared to 2022, attributable to reduced
advertising expenses and improved operating leverage. The earnings from GEICO’s insurance agency (third-party
commissions, net of operating expenses) are included as a reduction of underwriting expenses.
2022 versus 2021
Premiums written increased $712 million (1.9%) in 2022 compared to 2021, reflecting increases in average premiums
per auto policy due to rate increases, which were substantially offset by a decrease in policies-in-force. Voluntary auto policiesin-force declined 8.9% in 2022 compared to 2021 while average premiums per auto policy increased 10.5%. Premiums earned
increased $1.3 billion (3.4%) in 2022 compared to 2021, partially attributable to a reduction in 2021 from the remaining impactof the GEICO Giveback program, which provided a premium reduction on voluntary auto and motorcycle policies from April
2020 to October 2020.
Losses and loss adjustment expenses increased $5.3 billion (17.1%) compared to 2021. GEICO’s loss ratio was 93.1%
in 2022, an increase of 10.9 percentage points over 2021. The increase was primarily attributable to higher claims frequencies
and significantly higher severities, as well as lower reductions of ultimate loss estimates for prior years’ events.
Claims frequencies in 2022 were higher for all coverages, including property damage (one to two percent range), bodily
injury and collision (four to five percent range) and personal injury (three to four percent range). Average claims severities in
2022 were higher for all coverages, including property damage (twenty-one to twenty-two percent range), collision (fourteen
to sixteen percent range) and bodily injury (nine to eleven percent range). Losses and loss adjustment expenses reflected
reductions in the ultimate loss estimates for prior years’ loss events of $653 million in 2022 and $1.8 billion in 2021. Losses
and loss adjustment expenses were approximately $400 million from Hurricane Ian in 2022 and $375 million from Hurricane
Ida in 2021.
Underwriting expenses decreased $881 million (16.2%) in 2022 compared to 2021, primarily due to significant
reductions in advertising costs and lower employee-related costs. GEICO’s expense ratio was 11.7% in 2022, a decrease of 2.8
percentage points compared to 2021, attributable to both the decrease in expenses as well as higher premiums earned.

Management’s Discussion and Analysis
Insurance—Underwriting
Berkshire Hathaway Primary Group (Continued)
Premiums written increased $3.5 billion (24.1%) in 2023 compared to 2022. The increase was primarily due to RSUI
and CapSpecialty ($2.1 billion), as well as comparative increases from BHSI and BH Direct, and to a lesser extent the otherbusinesses. Premiums written increased $2.0 billion (16.1%) in 2022 compared to 2021, reflecting increases at BHSI (16%),USLI (16%), BHHC (15%) and MedPro Group (10%) across a variety of coverages and in several markets, and from theacquisition of RSUI and CapSpecialty ($435 million).
Losses and loss adjustment expenses increased $1.3 billion (13.5%) in 2023 compared to 2022, which increased $1.8
billion (22.0%) versus 2021. The loss ratio decreased 6.4 percentage points in 2023 compared to 2022, reflecting lower incurred
losses from current year catastrophes and changes in business mix, including the impact of RSUI and CapSpecialty.
Incurred losses from significant catastrophes were $37 million in 2023 and $641 million in 2022. Incurred losses andloss adjustment expenses also reflected net reductions in estimated ultimate liabilities for prior years’ loss events of $537
million in 2023 and $428 million in 2022, primarily due to reductions in ultimate medical professional liability and property
losses. In 2021, we incurred losses of $433 million from significant catastrophes and recorded net reductions in estimatedultimate liabilities for prior years’ loss events of $631 million.
BH Primary insurers write significant levels of workers’ compensation, commercial and professional liability insurance
and the related claim costs may be subject to high severity and long claim-tails. Ultimate claim liabilities could be greater than
anticipated due to a variety of factors, including adverse legal and judicial rulings.
Underwriting expenses increased $1.1 billion (30.8%) in 2023 compared to 2022 and $603 million (21.1%) in 2022
compared to 2021. The increases were primarily attributable to the increases in premiums earned and changes in business mix,
including the effects of the acquisition of RSUI and CapSpecialty.
Berkshire Hathaway Reinsurance Group
The Berkshire Hathaway Reinsurance Group (“BHRG”) offers excess-of-loss and quota-share reinsurance coverages onproperty and casualty risks to insurers and reinsurers worldwide through several subsidiaries, led by National Indemnity
Company (“NICO”), General Reinsurance Corporation, General Reinsurance AG and, beginning on October 19, 2022, TransReGroup. We also write life and health reinsurance coverages through General Re Life Corporation, General Reinsurance AG
and Berkshire Hathaway Life Insurance Company of Nebraska (“BHLN”). We assume property and casualty risks underretroactive reinsurance contracts written through NICO and we write periodic payment annuity contracts through BHLN.
A summary of BHRG’s premiums and pre-tax underwriting results follows (in millions). The retrospective adoption of
ASU 2018-12 increased BHRG’s pre-tax underwriting earnings $76 million in 2022 and reduced pre-tax underwriting losses$175 million in 2021 from the amounts previously reported.

Premiums written in 2023 increased 31.8% over 2022, which increased 19.9% over 2021. Premiums written included$5.3 billion in 2023 and $1.0 billion in 2022 from TransRe Group. Excluding TransRe Group, premiums written in 2023
increased $1.1 billion (7.1%) compared to 2022, while premiums written increased 12.9% in 2022 compared to 2021. The
increase in 2023 reflected net increases in new property business and higher rates. We have written considerable levels ofproperty business in recent years and we generally do not retrocede the risks we assume. Our periodic underwriting earnings
are subject to considerable volatility from significant catastrophe loss events.
Losses and loss adjustment expenses increased $2.1 billion in 2023 and $727 million in 2022 versus the corresponding
prior year. Overall, the loss ratio declined 8.4 percentage points in 2023 compared to 2022, which decreased 5.8 percentage
points versus 2021. Losses included $3.2 billion in 2023 and $638 million in 2022 from TransRe Group. Excluding TransReGroup, losses and loss adjustment expenses decreased $509 million (5.1%) in 2023 compared to 2022 and increased $89 million
in 2022 compared to 2021. Losses incurred from significant current year catastrophes were approximately $900 million in
2023, $2.0 billion in 2022 and $2.1 billion in 2021. The reductions in estimated ultimate liabilities for losses occurring in prioraccident years were $1.4 billion in 2023, $1.6 billion in 2022 and $718 million in 2021, attributable to lower than expected
property and casualty losses.
Underwriting expenses increased $2.5 billion in 2023 compared to 2022. The expense ratio increased 6.0 percentage
points in 2023 compared to 2022, which declined 2.9 percentage points compared to 2021. The comparative changes in the
expense ratio were primarily attributable to changes in foreign currency exchange rates related to the remeasurement of certain
non-U.S. Dollar denominated liabilities and changes in business mix, including the impact of TransRe Group. Underwriting
expenses included pre-tax foreign currency exchange losses of $189 million in 2023 and gains of $371 million in 2022 and$173 million in 2021.

Pre-tax underwriting earnings in 2023 included a gain of $134 million from the commutation of several U.S. life
reinsurance contracts, which reduced premiums earned by $164 million and life and health benefits incurred and underwriting
expenses by $298 million. Otherwise, premiums earned were substantially unchanged and life benefits incurred decreased 5.3%
in 2023 versus 2022. The underwriting expense ratio increased 3.0 percentage points in 2023 versus 2022, primarily attributable
to the impact of the commutations and increased underwriting expenses.

K-40

Management’s Discussion and Analysis
Insurance—Underwriting
Berkshire Hathaway Reinsurance Group (Continued)
Premiums written declined $436 million (7.8%) in 2022 compared to 2021, primarily due to unfavorable foreign currencytranslation effects and, to a lesser extent, lower volume in the Asia-Pacific region. Life and health benefits incurred declined$637 million (13.4%) in 2022 compared to 2021, primarily due to high pandemic-related life claims in the U.S., South Africa,
India and Latin America in 2021.
Retroactive reinsurance
Pre-tax underwriting losses from retroactive reinsurance in each period derived from the amortization of deferred charges
and the effects of changes in the estimated timing and amounts of future claim payments. Underwriting results also included
pre-tax foreign currency exchange losses of $57 million in 2023 and pre-tax gains of $168 million in 2022 and $58 million in
2021. Before foreign currency exchange effects, pre-tax underwriting losses were $1.5 billion in 2023, $836 million in 2022
and $840 million in 2021.
Estimated ultimate claim liabilities increased $1.1 billion in the fourth quarter of 2023, which net of changes inunamortized deferred charges, produced pre-tax underwriting losses of approximately $650 million. The increase in ultimate
liabilities derived from higher asbestos, environmental and other casualty claims estimates. We increased estimated ultimate
claim liabilities for prior years’ contracts $86 million in 2022 and reduced estimated ultimate liabilities $974 million in 2021.
The reductions in 2021, net of changes in unamortized deferred charges, produced pre-tax underwriting earnings of $142
million.
Unpaid losses assumed under retroactive reinsurance contracts were $34.6 billion at December 31, 2023, a decline of$768 million since December 31, 2022. Unamortized deferred charges on retroactive reinsurance contracts were $9.5 billion at
December 31, 2023, a decline of $375 million since December 31, 2022. Deferred charge amortization will be included inunderwriting earnings over the expected remaining claims settlement periods.
Periodic payment annuity
Periodic payment annuity business is price and demand sensitive and the supply of available business is affected by thetiming of underlying legal claim settlements. Our volumes written may change rapidly due to changes in prices, as well as thelevel of competition. Beginning in the latter part of 2022, prices for new business declined to unacceptable levels and we havesince not written new business.
Our periodic payment annuity contracts produced pre-tax underwriting losses in each period from the recurring accretionof time-value discounted liabilities, which includes liabilities for contracts without life contingencies. Underwriting results also
included pre-tax foreign currency exchange losses of $60 million in 2023, gains of $71 million in 2022 and losses of $18
million in 2021.
Pre-tax underwriting losses before foreign currency exchange effects were $590 million in 2023, $694 million in 2022
and $554 million in 2021. Losses in 2022 included approximately $130 million from the termination of an existing reinsurance
contract in which the settlement payable exceeded the carrying value of the liabilities. Discounted periodic payment annuity
liabilities were $15.2 billion at December 31, 2023, including liabilities of $4.0 billion for contracts without life contingencies.
We adopted ASU 2018-12 on January 1, 2023, which requires quarterly adjustments of the discount rates on contracts withlife-contingent liabilities based upon prevailing interest rates, with the effects of discount rate changes included in othercomprehensive income.
Variable annuity
Our variable annuity guarantee reinsurance contracts produced pre-tax earnings of $233 million in 2023, $467 million in
2022 and $169 million in 2021. Earnings are affected by changes in securities markets, interest rates and foreign currency
exchange rates, which can be volatile. These contracts have been in run-off for many years.

Dividend income declined $539 million (8.9%) in 2023 compared to 2022 and increased $979 million (19.3%) in 2022
compared to 2021. The reduction in 2023 reflected the impact of net dispositions of investments since the end of the third
quarter of 2022, partially offset by higher dividend rates on certain of our holdings. The increase in 2022 was primarily
attributable to a net increase in equity security investments. Dividend income also included $34 million in 2023, $46 million
in 2022 and $121 million in 2021 from BHE preferred stock. Such amounts were deducted from earnings of the BHE segment.
Dividend income varies from period to period due to changes in the investment portfolio and the frequency and timing ofdividends from certain investees.
Interest and other investment income increased $4.4 billion in 2023 compared to 2022 and increased $1.1 billion in 2022
compared to 2021. The increases were primarily due to increases in interest rates, as well as the inclusion of interest income
from Alleghany’s insurance subsidiaries. We continue to hold substantial balances in short-term investments, including U.S.
Treasury Bills. We continue to believe that maintaining ample liquidity is paramount and we insist on safety over yield withrespect to short-term investments.
Invested assets of our insurance businesses derive from shareholder capital and net liabilities assumed under insurance
and reinsurance contracts or “float.” The major components of float are unpaid losses and loss adjustment expenses, including
liabilities under retroactive reinsurance contracts, life, annuity and health benefit liabilities, unearned premiums and otherliabilities due to policyholders, which are reduced by insurance premiums receivable, reinsurance receivables, deferred charges
assumed under retroactive reinsurance contracts and deferred policy acquisition costs. The effect of discount rate changes
recorded in accumulated other comprehensive income in the Consolidated Balance Sheets for long-duration insurance contracts
are excluded from float, as such amounts are not included in underwriting earnings in the Consolidated Statements of Earnings.
Float was approximately $169 billion at December 31, 2023, $164 billion at December 31, 2022 and $147 billion at December
31, 2021. Our combined insurance operations generated pre-tax underwriting gains in 2023 and 2021, and the average cost of
float was negative in those years. Our pre-tax underwriting losses in 2022 were $22 million and the cost of float was nominal.

2023 versus 2022
Railroad operating revenues declined 6.9% in 2023 compared to 2022, reflecting an overall volume decrease of 5.7%
and a decrease in average revenue per car/unit of 0.6%, primarily attributable to lower fuel surcharge revenue, partially offset
by favorable price and mix. Pre-tax earnings were $6.6 billion in 2023, a decline of 14.2% from 2022, reflecting lower volumes
and higher non-fuel operating costs, partially offset by lower fuel costs.

K-43

Management’s Discussion and Analysis
Railroad
Operating revenues from consumer products declined 14.7% in 2023 to $7.9 billion compared to 2022, reflecting a
volume decrease of 8.4% and lower average revenue per car/unit. The volume decrease was primarily due to lower intermodal
shipments resulting from reduced West Coast imports, the loss of an intermodal customer and competition from lower spot
rates in the trucking market, which has impacted our domestic intermodal demand. These declines were partially offset by anincrease in automotive volume from higher vehicle production.
Operating revenues from industrial products were $5.7 billion in 2023, an increase of 1.8% from 2022, reflecting higher
average revenue per car/unit, partially offset by a volume decrease of 0.8%. The volume decline was primarily due to lower
demand for chemicals, plastics, minerals, paper and lumber, partially offset by increased shipments of steel and aggregatesfrom infrastructure demand.
Operating revenues from agricultural products decreased 2.8% to $5.6 billion in 2023 compared to 2022, attributable toa volume decrease of 2.9%, partially offset by slightly higher average revenue per car/unit. The volume decrease was primarily
due to lower grain exports, partially offset by higher volumes of domestic grains and feedstocks and renewable diesel.
Operating revenues from coal declined 3.4% to $3.8 billion in 2023 compared to 2022. The revenue decrease wasattributable to a volume decrease of 4.0%, partially offset by higher average revenue per car/unit. The volume decline reflectedmoderating demand attributable to lower natural gas prices.
Railroad operating expenses were $16.1 billion in 2023, a decline of $541 million (3.3%) compared to 2022. The ratioof railroad operating expenses to railroad operating revenues increased 2.5 percentage points to 68.4% in 2023 versus 2022.
Fuel expenses declined $897 million (19.6%) compared to 2022, reflecting lower average fuel prices, lower volumes andimproved efficiency. Compensation and benefits expenses increased $247 million (4.7%) in 2023 compared to 2022, primarily
due to higher headcount and wage inflation. Other revenues (expenses), net increased 90% compared to 2022, primarily due toan increase in interest income driven by higher interest rates.
2022 versus 2021
Railroad operating revenues increased 11.9% in 2022 compared to 2021, reflecting an 18.9% increase in average revenue
per car/unit, including the impact from higher fuel surcharge revenue driven by higher fuel prices, partially offset by lower
volumes of 5.8%. BNSF’s pre-tax earnings decreased 1.9% in 2022 from 2021. Pre-tax earnings in 2022 were impacted bylower volumes and higher fuel and other operating costs, offset by higher yield and fuel surcharge revenue.
Operating revenues from consumer products increased 11.8% in 2022 to $9.2 billion compared to 2021, reflecting higher
average revenue per car/unit, partially offset by a volume decrease of 8.3%. The volume decrease was primarily due to lower
intermodal shipments, resulting from supply chain disruptions and lower West Coast imports during the second half of the year.
Operating revenues from industrial products were $5.6 billion in 2022, an increase of 5.6% from 2021, reflecting higher
average revenue per car/unit, partially offset by a volume decrease of 5.3%. The volume decrease was primarily due to adecrease in petroleum products related to lower demand for shipments of crude by rail and lower building products, steel andtaconite shipments, partially offset by increased mineral shipments.
Operating revenues from agricultural products increased 12.6% to $5.7 billion in 2022 compared to 2021. The revenue
increase reflected higher revenue per car/unit partially offset by lower volumes of 2.0%. The decrease in volumes was primarily
due to lower grain exports and fertilizer shipments, partially offset by higher volumes of domestic grains, renewable diesel andfeedstocks.
Operating revenues from coal increased 21.7% to $3.9 billion in 2022 compared to 2021, attributable to higher averagerevenue per car/unit. Coal volumes were unchanged compared to 2021.
Railroad operating expenses were $16.6 billion in 2022, an increase of $2.9 billion (21.2%) compared to 2021. Our ratioof railroad operating expenses to railroad operating revenues increased 5.0 percentage points to 65.9% in 2022 versus 2021.
The operating expense increase was primarily attributable to significant increases in the cost of fuel, as well as higher
compensation and benefits expenses. Compensation and benefits expenses increased $557 million (11.9%) in 2022 compared
to 2021, primarily due to wage inflation, including the impact from the ratified union labor agreements, higher health andwelfare costs and lower productivity. Fuel expenses increased $1.8 billion (65.6%) in 2022 compared to 2021, primarily due
to higher average fuel prices, partially offset by lower volumes. Equipment rents, materials and other expenses increased $384
million (21.8%) in 2022 compared to 2021, due to general inflation, lower gains from land and easement sales and higher
casualty and litigation costs.

Utilities and Energy
We currently own 92% of Berkshire Hathaway Energy Company (“BHE”), which operates a global energy business.
BHE’s domestic regulated utility interests include PacifiCorp, MidAmerican Energy Company (“MEC”) and NV Energy.
BHE’s natural gas pipelines consist of five domestic regulated interstate natural gas pipeline systems and a liquefied natural
gas export, import and storage facility. Other energy businesses include subsidiaries that operate two regulated electricity
distribution businesses in Great Britain (“Northern Powergrid”), a regulated electricity transmission-only business in Alberta,
Canada, a diversified portfolio of mostly renewable independent power projects and investments and an unregulated retailenergy services company. BHE also operates a residential real estate brokerage business and a large network of real estate
brokerage franchises in the United States.
The rates our regulated businesses charge customers for energy and services are largely based on the costs of business
operations, including income taxes and a return on capital, and are subject to regulatory approval. To the extent such costs are
not allowed in the approved rates, operating results will be adversely affected. A summary of BHE’s net earnings follows(dollars in millions).

Utilities and Energy
2023 versus 2022
Our U.S. utilities operate independently in several states, including Oregon, Utah, Wyoming and other Western states(PacifiCorp), Iowa and Illinois (MEC) and Nevada (NV Energy). After-tax earnings decreased $1.4 billion in 2023 compared
to 2022. The decline reflected an increase in energy operating expenses, including an increase in estimated pre-tax loss accruals
of $1.6 billion, net of expected insurance recoveries, for wildfires in 2020 and in 2022 that arose in Oregon and California(“Wildfires”). See Note 27 to the Consolidated Financial Statements for additional information on the Wildfires. The decline
in earnings also reflected higher interest expense and lower electric utility margin (operating revenue less cost of sales). These
items were partially offset by increases in interest and other income and lower depreciation and amortization expense.
The U.S. utilities’ electric utility margin was $7.5 billion in 2023, a decrease of $170 million (2.2%) versus 2022. The
decline reflected lower volumes and wholesale rates, as well as increased energy costs, partially offset by an increase in retailcustomer rates in certain territories. Retail customer volumes decreased 0.8% overall (down 0.8% at PacifiCorp and 2.6% at
NV Energy and up 1.3% at MEC) in 2023 compared to 2022, primarily due to the unfavorable impact of weather, partially
offset by higher customer usage and an overall increase in the average number of customers.
After-tax earnings of natural gas pipelines increased $39 million (3.8%) in 2023 compared to 2022. The increase reflected
higher regulated transportation and storage services revenues from certain general rate cases and increased earnings from theacquisition of an additional 50% ownership interest in the Cove Point liquefied natural gas export, import and storage facility
on September 1, 2023, partially offset by higher operating expenses.
After-tax earnings of other energy businesses decreased $332 million (24.5%) in 2023 compared to 2022. The declinereflected lower earnings at Northern Powergrid due to unfavorable results at a natural gas exploration project, including thewrite-off of capitalized exploration costs and lower gas production volumes and prices, as well as from higher deferred income
tax expense related to the enactment of the Energy Profits Levy income tax in the United Kingdom. The earnings decline wasalso attributable to lower earnings from renewable energy and retail services businesses. The decline in renewable energy andretail services earnings was primarily due to lower income tax benefits, higher operating expenses, lower solar and wind
generation at owned projects and the impact of unfavorable changes in valuations of derivatives contracts, partially offset bydebt extinguishment gains.
After-tax earnings of real estate brokerage decreased $87 million (87.0%) in 2023 compared to 2022. The decreasereflected lower brokerage services revenues and margins, primarily due to a 19% reduction in closed brokerage transaction
volumes, as well as lower mortgage services revenues and margins from a 28% decrease in closed transaction volumes. These
declines were attributable to the impact of rising interest rates and lower existing home sales.
Corporate interest and other after-tax earnings increased $27 million in 2023 compared to 2022, reflecting higher interest
and other income, partially offset by unfavorable consolidated income tax adjustments, largely state-related, and higher BHE
corporate interest expense from an April 2022 debt issuance.
2022 versus 2021
The U.S. utilities after-tax earnings increased $84 million in 2022 compared to 2021. The earnings increase reflected
higher electric utility margin and a $157 million increase in production tax credits recognized on new wind-powered generating
facilities placed in-service at PacifiCorp and MEC, partially offset by higher operating expenses and state income taxes.
Operating expenses increased due to higher costs associated with certain regulatory mechanisms at MEC and NV Energy,
increases in general and plant maintenance costs, incremental depreciation expense from additional assets placed in-service
and an increase in estimated pre-tax loss accruals of $60 million for the Wildfires, net of expected insurance recoveries.
The U.S. utilities’ electric utility margin was $7.7 billion in 2022, an increase of $586 million (8.3%) compared to 2021.
The increase reflected higher operating revenue from favorable retail and wholesale pricing and increases in retail customer
volumes, partially offset by increases in thermal generation and purchased power costs. Retail customer volumes increased
2.4% (1.6% at PacifiCorp, 4.3% at MEC and 2.2% at NV Energy) in 2022 compared to 2021, primarily due to higher customer
usage, an increase in the average number of customers and the favorable impact of weather.

K-46

Management’s Discussion and Analysis
Utilities and Energy
Natural gas pipelines’ after-tax earnings increased $233 million in 2022 compared to 2021. Substantially all of theincrease was derived from BHE GT&S, primarily attributable to higher regulated storage and service revenues from a general
rate case settlement and higher revenues and margins from non-regulated activities, as well as income tax adjustments.
Other energy businesses’ after-tax earnings increased $369 million in 2022 compared to 2021. The increase was primarily
due to increased wind tax equity investment earnings of $200 million and the impact in 2021 on income tax expense of $109
million related to the enactment in 2021 of an increase in the United Kingdom corporate income tax rate from 19% to 25%,
effective April 1, 2023. The earnings increase also reflected higher operating revenue from owned renewable energy projects
and earnings from new gas exploration and solar projects, partially offset by lower earnings from natural gas generating
facilities and unfavorable foreign currency translation effects. The increase in wind tax equity investment earnings was
attributable to the impact of losses in 2021 on pre-existing tax equity investments due to the February 2021 winter storms, aswell as increased income tax benefits from projects reaching commercial operation over the past twelve months.
Real estate brokerage after-tax earnings decreased $287 million in 2022 compared to 2021. The decrease reflected lower
brokerage services revenues and margins, primarily due to an 11% reduction in closed brokerage transaction volumes, as well
as lower mortgage services revenues and margins from a 40% decrease in closed transaction volumes, attributable to lower
homeowner refinancing activity resulting from rising interest rates.
Corporate interest and other after-tax earnings decreased $94 million in 2022 compared to 2021. The decrease wasprimarily due to lower state income tax benefits and higher interest expense from corporate debt issued in 2022.

PTC operates travel centers, primarily under the names Pilot or Flying J, and fuel-only retail locations. PTC also operates
large wholesale fuel and fuel marketing platforms in the U.S. A substantial portion of PTC’s revenues and earnings derive frommarketing fuel on a wholesale and retail basis and from other energy-related activities.
Through January 31, 2023, we owned a 38.6% interest in PTC, which we accounted for under the equity method. Our

Management’s Discussion and Analysis
Pilot Travel Centers, LLC (“PTC”)
PTC’s revenues and earnings are highly dependent on diesel fuel and gasoline volumes, prices and margins. Revenues
for the twelve months ended December 31, 2023 were approximately $56.8 billion, a decline of $16.0 billion (22.0%) from2022. The decline reflected lower fuel prices, as well as lower fuel sales volumes and in-store sales. PTC sold approximately
16.2 billion gallons of diesel fuel, gasoline and other fuel-related products in 2023 compared to 18.4 billion gallons in 2022.
The decline in fuel volumes was predominantly in the wholesale fuel and fuel marketing businesses. Cost of sales in 2023
reflected lower fuel costs than in 2022. Depreciation and amortization expense was $832 million in 2023 and $436 million in
2022. The increase was due to the application of acquisition accounting beginning on February 1, 2023. Interest expense
increased $213 million in 2023 compared to 2022, primarily due to higher interest rates.

Management’s Discussion and Analysis
Manufacturing, Service and RetailingIndustrial products
The industrial products group includes metal products for aerospace, power and general industrial markets (Precision
Castparts Corp. (“PCC”)), specialty chemicals (The Lubrizol Corporation (“Lubrizol”)), metal cutting tools/systems (IMC
International Metalworking Companies (“IMC”)), and Marmon, which consists of more than 100 autonomous manufacturing
and service businesses, internally aggregated into eleven groups, and includes equipment leasing for the rail, intermodal tankcontainer and mobile crane industries. The industrial products group also includes equipment and systems for the livestock andagricultural industries (CTB International) and a variety of industrial products for diverse markets (Scott Fetzer andLiquidPower Specialty Products). Beginning October 19, 2022, this group includes the structural steel fabrication products
business conducted through W&W|AFCO Steel (“W&W|AFCO”), acquired in connection with the Alleghany acquisition.
Additionally, the Alleghany acquisition included certain other smaller manufacturers that became part of Marmon.
2023 versus 2022
Revenues of the industrial products group in 2023 increased $4.1 billion (13.2%) and pre-tax earnings increased $824
million (16.9%) compared to 2022. Pre-tax earnings as a percentage of revenues in 2023 was 16.3%, an increase of 0.5
percentage points compared to 2022.
PCC’s revenues were $9.3 billion in 2023, an increase of $1.7 billion (22.7%) compared to 2022. PCC derives significant
revenues and earnings from aerospace products. The revenue increase in 2023 was primarily attributable to higher demand foraerospace products, while power/energy and general and industrial products also contributed to the overall revenue increase.
Long-term industry forecasts continue to show growth and strong demand for air travel and aerospace products.
PCC’s pre-tax earnings were $1.5 billion in 2023, an increase of 30.0% compared to 2022. The improved results in 2023
reflected increases in sales and improving manufacturing and operating efficiencies in aerospace businesses, partially offset by
operating losses in energy products businesses. PCC continues to strive to improve manufacturing efficiencies, maintain safety
and prepare for increasing demand for its products. Continued growth in PCC’s revenues and earnings will be predicated on
the ability to successfully increase production levels to match the expected growth in aerospace product demand.
Lubrizol’s revenues were $6.4 billion in 2023, a decline of 4.0% compared to 2022. The revenue decline was primarily
due to a 7.9% decline in volumes and unfavorable foreign currency effects, partially offset by higher selling prices. The decline
in sales volumes in 2023 was attributable to general market weakness and customer efforts to reduce their inventory levels.
Lubrizol’s pre-tax earnings in 2023 were relatively unchanged compared to 2022. Earnings included insurance recoveries
of $11 million in 2023 and $242 million in 2022 in connection with fires at the Rockton, Illinois facility in 2021 and the Rouen,
France facility in 2019. Excluding insurance recoveries, earnings in 2023 were higher due to the favorable impacts of higher
selling prices, favorable changes in product mix and lower raw material costs, partially offset by the impact of lower sales
volumes, unfavorable foreign currency translation effects and higher operating expenses.
Marmon’s revenues were $11.9 billion in 2023, an increase of $1.2 billion (11.6%) compared to 2022. Businessacquisitions, including AP Emissions Technologies and three former Alleghany businesses: Kentucky Trailer, Wilbert Funeral
Services, Inc. and Wilbert Plastics Services, accounted for substantially all of the comparative increase. In addition, the Rail &Leasing, Water Technologies, Medical, Metal Services and Crane Services groups generated higher revenues in 2023, primarily
due to higher volumes and pricing improvements. Revenues in 2023 of the Electrical group’s building wire business and theMetal Services and Plumbing & Refrigeration groups were negatively impacted by lower metals prices, while revenues of theTransportation Products group reflected reduced customer demand, which accelerated over the second half of 2023.
Marmon’s pre-tax earnings increased 13.1% in 2023 compared to 2022. The earnings increase reflected the favorable
impact of business acquisitions of $90 million and losses of approximately $90 million in 2022 from the shutdown of the Rail& Leasing group business in Russia. Earnings from eight of Marmon’s eleven business groups increased in 2023 compared to2022. The Rail & Leasing, Water Technologies and Plumbing & Refrigeration groups generated higher organic earnings in
2023, which were offset by lower earnings from the Electrical group’s building wire business and from the Metals Services
and Medical groups.

K-49

Management’s Discussion and Analysis
Manufacturing, Service and Retailing
IMC’s revenues increased 8.0% to $4.0 billion in 2023 compared to 2022. The increase reflected the impact of businessacquisitions, organic sales growth in North America and other regions and higher interest income due to higher interest rates,
partially offset by lower revenues in the Asia-Pacific region, unfavorable foreign currency translation from a stronger U.S.
Dollar and the impact of ongoing geopolitical conflicts. IMC’s pre-tax earnings increased 6.9% in 2023 compared to 2022,
primarily attributable to higher interest income and to a lesser extent increased operating earnings. The impact of the revenue
increase was largely offset by higher raw material costs, changes in sales mix and the adverse effects of geopolitical conflicts.
A large portion of IMC’s products are manufactured in Israel. To date, IMC’s operations in Israel have not been significantly
impacted by the terrorist attack on Israel on October 7, 2023, and the ongoing conflicts in the region.
2022 versus 2021
Revenues of the industrial products group increased $2.6 billion (9.4%) and pre-tax earnings increased $393 million(8.8%) in 2022 compared to 2021. Pre-tax earnings as a percentage of revenues in 2022 was 15.8%, a decrease of 0.1 percentage
points compared to 2021.
PCC’s revenues were $7.5 billion in 2022, an increase of $1.1 billion (16.5%) compared to 2021. The revenue increasein 2022 was primarily attributable to higher demand for aerospace products. Commercial aircraft delivery rates by original
equipment manufacturers (“OEMs”) of narrow-body aircraft rebounded since the onset of the pandemic. Deliveries of widebody aircraft were relatively low, in part, attributable to the pause in the Boeing 787 program. However, Boeing resumeddeliveries in the third quarter of 2022.
PCC’s pre-tax earnings were $1.2 billion in 2022, an increase of 1.6% compared to 2021. PCC’s results in 2022 were
negatively affected by increased costs for labor and training, materials and utilities and supply chain disruptions, as well as a
$59 million reduction in pension plan income.
Lubrizol’s revenues were $6.7 billion in 2022, an increase of 3.2% compared to 2021. The revenue increase reflected
higher average selling prices, partially offset by lower volumes and adverse foreign currency translation effects from thestronger U.S. Dollar. Sales volumes throughout 2022 were restricted by effects of supply constraints for certain raw materials
and the effects of unplanned plant maintenance activities, both of which limited Lubrizol’s production capabilities. The increasein average selling prices was driven by escalating prices for raw materials, including oil feedstocks, as well as for utilities,
packaging, shipping and freight costs.
Lubrizol’s pre-tax earnings increased 48.6% in 2022 compared to 2021. Pre-tax earnings in 2022 and 2021 included
insurance recoveries of $242 million and $55 million, respectively, related to the Rockton and Rouen fires. Earnings in 2022
also included aggregate losses related to the Rockton fire of $36 million compared to aggregate losses and asset impairment
charges in 2021 of $257 million related to the Rockton fire and an underperforming business in the Advanced Materials productlines. Earnings in 2022 were also negatively impacted by rising raw material costs, lower sales volumes, higher unplanned
maintenance expenses, and by unfavorable foreign currency translation effects, partially offset by higher selling prices.
Earnings in 2021 were negatively impacted by severe winter storms, which caused industry-wide temporary facilities closures,
including at our Additives facilities, which experienced lost sales and incremental operating costs.
Marmon’s revenues were $10.7 billion in 2022, an increase of $934 million (9.6%) compared to 2021. Nearly all of
Marmon’s business groups generated higher revenues in 2022, led by significant increases in the Transportation, Retail
Solutions, Metal Services and Crane groups, which contributed 82% of the increase. These increases generally reflected higher
volumes and prices in our heavy-duty truck & trailer, shopping cart and store shelving businesses, stronger demand in Canada
for metal services and higher demand in the mining and infrastructure markets. Revenues of most of Marmon’s other groups,
particularly those serving the transit, oil & gas, utility and restaurant markets, also increased in 2022, reflecting higher volumes.
These increases were partially offset by lower lease revenues in the Rail & Leasing group, reflecting lower renewal rates andfewer third-party tank car sales.

K-50

Management’s Discussion and Analysis
Manufacturing, Service and Retailing
Marmon’s pre-tax earnings increased 11.3% in 2022 compared to 2021. Earnings in 2022 reflected increases in theTransportation, Metal Services, Retail, Crane and several other business groups due to higher volumes and pricing, which werepartially offset by lower earnings from the Rail & Leasing group, reflecting lower renewal rates, higher repair costs and thelosses related to the shutdown of its business in Russia.
IMC’s revenues increased 4.5% to $3.7 billion in 2022 compared to 2021, reflecting increased sales in most regions,partially offset by the foreign currency translation effects of a stronger U.S. Dollar, lower sales in China (attributable to thepandemic) and the effects of the Russia-Ukraine conflict in Europe. IMC’s pre-tax earnings decreased 2.5% in 2022 compared
to 2021, primarily due to lower average gross sales margins from changes in product sales mix and higher raw material costs.
Earnings were also negatively affected by unfavorable foreign currency translation effects and the Russian-Ukraine conflict.
Building products
The building products group includes manufactured and site-built home construction and related lending and financial
services (Clayton Homes), flooring (Shaw), insulation, roofing and engineered products (Johns Manville), bricks and masonry
products (Acme Building Brands), paint and coatings (Benjamin Moore) and residential and commercial construction andengineering products and systems (MiTek).
2023 versus 2022
Revenues of the building products group decreased $2.9 billion (10.1%) and pre-tax earnings decreased $602 million(12.6%) in 2023 compared to 2022. Pre-tax earnings as percentages of revenues were 16.1% in 2023 and 16.6% in 2022. Ourbuilding products businesses benefited in recent years from the low interest rate environment and strong residential andcommercial construction markets. The effects of significant increases in home mortgage interest rates in the U.S. over the past
year has slowed demand for our home building businesses and our other building products businesses. Such effects have been
partially mitigated by new construction activity, resulting from low supplies of pre-existing homes for sale.
Clayton Homes’ revenues were approximately $11.4 billion in 2023, a decrease of $1.3 billion (10.3%) compared to2022. Revenues from home sales decreased $1.6 billion (15.3%) in 2023 to approximately $8.8 billion, primarily due to lower
unit sales and changes in product mix. New home unit sales declined 13.7% in 2023, reflecting lower factory-built and sitebuilt homes. Financial services revenues, which include mortgage, insurance and interest income from lending activities,
increased 12.2% in 2023 compared to 2022, primarily due to increased interest income on higher average loan balances. Loanbalances, net of allowances for credit losses, were approximately $23.8 billion as of December 31, 2023, an increase of
approximately $2.5 billion from December 31, 2022.
Pre-tax earnings of Clayton Homes were approximately $2.0 billion in 2023, a decrease of $326 million (13.8%)
compared to 2022. Earnings in 2023 reflected lower earnings from the home building businesses, partially offset by increased
earnings from financial services. The decline in earnings from the home building businesses reflected the reduction in sales, alower overall gross sales margin rate and higher operating expenses relative to sales. The increase in financial services earnings
was primarily attributable to increased net interest income, partially offset by increased expected loan loss provisions and higher
insurance claims.
Aggregate revenues of our other building products businesses were approximately $14.5 billion in 2023, a decrease of
10.0% versus 2022. The decline in revenues reflected overall lower sales volumes and changes in product mix, partly offset byhigher average selling prices.
Pre-tax earnings of the other building products businesses were approximately $2.1 billion in 2023, a decrease of 11.4%
compared to 2022. Pre-tax earnings as a percentage of revenues were 14.7% in 2023, a 0.3 percentage point decrease compared
to 2022. The earnings decline in 2023 was driven by lower sales volumes, reduced manufacturing efficiencies and higher losses
from restructurings, plant closures and divestitures in 2023, partially offset by lower raw materials costs and energy costs aswell as reduced freight, shipping and utilities expenses. Earnings in 2022 benefited from higher selling prices, strong demandin certain product categories and an increase in gains from a business divestiture and asset sales.

Management’s Discussion and Analysis
Manufacturing, Service and Retailing
2022 versus 2021
Revenues of the building products group increased $3.9 billion (15.7%) in 2022 and pre-tax earnings increased $1.4
billion (41.3%) compared to 2021. Pre-tax earnings as percentages of revenues were 16.6% in 2022 and 13.6% in 2021. During2021 and much of 2022, our businesses experienced relatively strong customer demand and higher sales volumes. However,interest rates in the U.S. increased significantly during 2022, which contributed to slowing demand for new home constructionin the fourth quarter.
Clayton Homes’ revenues were approximately $12.7 billion in 2022, an increase of $2.2 billion (21.1%) over 2021.
Revenues from home sales for the year increased $2.1 billion (25.1%) in 2022 to approximately $10.4 billion, primarily due tohigher average selling prices. New home unit sales increased 6.2% in 2022, reflecting a 6.0% increase in factory-built
manufactured home unit sales and a 7.1% increase in site-built home unit sales. However, unit sales in the fourth quarter of2022 declined 3.9% from 2021, and our net order backlog declined significantly during 2022. Financial services revenues
increased 4.7% in 2022 compared to 2021. Loan balances, net of allowances for credit losses, were approximately $21.3 billion
as of December 31, 2022, an increase of approximately $2.5 billion from December 31, 2021. Actual and anticipated loan
foreclosures rose during the fourth quarter of 2022.
Pre-tax earnings of Clayton Homes were approximately $2.4 billion in 2022, an increase of $685 million (40.7%)
compared to 2021. Earnings in 2022 reflected higher home sales, gross margin rates and net interest income.
Aggregate revenues of the other building products businesses were approximately $16.2 billion in 2022, an increase of
11.8% versus 2021. The increase was primarily due to higher average selling prices, and to a lesser extent, from higher unit
volumes in certain product lines and product mix changes. Significant cost inflation in 2021, that continued through 2022,
largely drove the increases in selling prices.
Pre-tax earnings of the other building products businesses were approximately $2.4 billion in 2022, an increase of 41.9%
over 2021. Pre-tax earnings as a percentage of revenues were 15.0% in 2022, a 3.2 percentage point increase compared to 2021.
Earnings in 2022 benefited from higher selling prices and strong demand in certain product categories, as well as an increasein gains from certain business divestitures and asset sales and reduced impairment and restructuring charges. The increase inearnings in 2022 also reflected the negative impact of severe winter storms in the first quarter of 2021, which reduced sales andincreased production and other operating costs in 2021.
Consumer products
The consumer products group includes leisure vehicles (Forest River), several apparel and footwear operations (including
Fruit of the Loom, Garan, H.H. Brown Shoe Group and Brooks Sports) and a manufacturer of high-performance alkaline
batteries (Duracell). This group also includes custom picture framing products (Larson-Juhl), jewelry products (Richline) andbeginning October 19, 2022, Jazwares, LLC (“Jazwares”), a global toy company acquired in connection with the Alleghanyacquisition.
2023 versus 2022
Consumer products group revenues declined $1.5 billion (9.4%) in 2023 versus 2022. The decline reflected lower
revenues at Forest River and our apparel and footwear operations, partially offset by the impact of the Jazwares acquisition,
which contributed revenues of $1.3 billion in 2023 and $240 million in 2022.
Forest River revenues declined 26.2% in 2023 compared to 2022, reflecting a 29.3% decline in unit sales and changes insales mix. Forest River experienced strong recreational vehicle unit sales in 2021 and through the first half of 2022. Throughmost of 2023, sales of recreational vehicles declined significantly, attributable in part to the impact of rising interest rates,
inflation and other macroeconomic conditions. The decline in recreational vehicle sales was partially offset by increased sales
from Forest River’s bus and commercial business.
Revenues of our apparel and footwear businesses declined $452 million (9.4%) in 2023 compared to 2022. The decline
was primarily due to reduced apparel revenues, attributable to lower unit volumes, partially offset by higher average selling
prices. Duracell’s revenues in 2023 were relatively flat versus 2022.

K-52

Management’s Discussion and Analysis
Manufacturing, Service and Retailing
Pre-tax earnings of the consumer products group increased $46 million (3.0%) in 2023 compared to 2022. Pre-tax
earnings in 2023 reflected the impact of the Jazwares acquisition and higher earnings from the apparel and footwear businesses,
partially offset by lower earnings from Forest River and Duracell. Certain of our apparel and footwear businesses took actionsin 2023 to reduce inventories and right-size operations. The earnings decline at Forest River was primarily due to the impactof lower sales volumes, while the decline at Duracell was primarily attributable to higher restructuring costs.
2022 versus 2021
Consumer products group revenues increased $481 million (3.1%) in 2022 versus 2021, reflecting an 8.0% increase from
Forest River and the impact of the Jazwares acquisition, substantially offset by lower apparel and footwear and Duracell
revenues (4.7% in the aggregate). In the fourth quarter of 2022, consumer products group revenues before the impact of the
Jazwares acquisition declined 15.7%, driven by significant declines in recreational vehicle unit sales. The declines in appareland footwear revenues were driven by lower volumes, as major retailers reduced orders in response to rising inventories.
Duracell’s revenue decline was primarily due to lower volumes and unfavorable foreign currency translation effects of thestronger U.S. Dollar.
Pre-tax earnings of the consumer products group declined $456 million (23.0%) in 2022 compared to 2021 and as apercentage of revenues in 2022 decreased 3.2 percentage points to 9.5%. The earnings decline reflected lower earnings fromthe apparel and footwear businesses (68.0%) and Duracell (30.6%), partially offset by higher earnings from Forest River
(7.6%).
Our apparel businesses were negatively affected in 2022 by low sales volumes, reduced manufacturing efficiencies andhigher input costs, including raw materials, freight, labor and other operating costs. The reductions in sales volumes and supply
chain issues in 2021 and 2022 also elevated inventories. We began taking measures to right-size our operations for the longterm and reduce product inventories to more appropriate levels. Duracell’s earnings in 2022 declined, primarily due to lower
sales, cost inflation and foreign currency translation effects.
Earnings from Forest River increased in 2022, primarily due to an increase in unit sales in the first half of the year andhigher average selling prices, partly offset by higher materials costs. However, unit sales and earnings declined over the second
half of the year compared to the elevated levels in the first half of 2022 and in 2021.

ServiceOur service group consists of several businesses. The largest of these businesses are NetJets and FlightSafety (aviation
services), which offer shared ownership programs for general aviation aircraft and high technology training products andservices to operators of aircraft, and TTI, a distributor of electronics components. Our other service businesses franchise andservice a network of quick service restaurants (Dairy Queen), lease transportation equipment (XTRA) and furniture (CORT),
provide third party logistics services that primarily serve the petroleum and chemical industries (Charter Brokerage), distributeelectronic news, multimedia and regulatory filings (Business Wire) and operate a television station in Miami, Florida (WPLG).
Beginning, October 19, 2022, this group includes IPS-Integrated Project Services, LLC (IPS), a provider of various facilities
construction management services.
2023 versus 2022
Revenues of the service group increased $1.6 billion (8.3%) in 2023 compared to 2022. IPS produced revenues of $1.3
billion in 2023 and $358 million in 2022. Revenues from aviation services increased 11.5% in 2023 compared to 2022,
primarily due to increases in the number of aircraft in shared aircraft ownership programs and a year-to-date increase in flight
hours across NetJets’ various programs, as well as higher average rates.
Revenues from TTI declined 2.7% in 2023 compared to 2022. Excluding the effects of business acquisitions in 2022 and2023 and favorable foreign currency translation effects, revenues declined 5.2% in 2023 versus 2022. TTI experienced
significant revenue growth in 2021 and much of 2022. New orders throughout 2023 slowed in several regions, particularly in
the Asia-Pacific region, attributable to elevated customer inventory levels and increasing price competition. We currently
expect these conditions will persist in 2024.
Pre-tax earnings of the service group decreased $52 million (1.7%) in 2023 to $3.0 billion. Pre-tax earnings as apercentage of revenues were 14.5% in 2023, a decrease of 1.5 percentage points compared to 2022. The change in comparative
earnings in 2023 reflected lower earnings from TTI and certain of our other service businesses, partially offset by increased
earnings from aviation services and the impact of the IPS acquisition. Earnings from TTI declined 17.3%, attributable toreduced sales and gross margin rates and higher operating expenses, partly offset by the impact of foreign currency exchange
gains in 2023 compared to losses in 2022. The increase in earnings from aviation services was primarily attributable to a 14.4%
increase in average aircraft in the NetJets’ programs and higher rates.
2022 versus 2021
Service group revenues increased $3.1 billion (19.7%) in 2022 compared to 2021, primarily attributable to revenue
increases from TTI and aviation services, as well as the impact of the IPS acquisition. Revenues from TTI increased 17.4% in
2022 versus 2021. However, in the third quarter of 2022, new orders began to slow, attributable in part to elevated inventory
levels within the supply chain. Revenues from aviation services increased 18.2% in 2022 compared to 2021. The revenue
increase reflected increases in training hours (11%), customer flight hours (9%) and fuel surcharges to customers due to theincrease in flight hours and fuel prices. The impact of these increases were partially offset by changes in sales mix.
Pre-tax earnings of our service group increased $375 million (14.0%) in 2022 to $3.0 billion. Pre-tax earnings as apercentage of revenues were 16.0% in 2022, a decrease of 0.8 percentage points compared to 2021. The earnings increase in
2022 was attributable to TTI (19.4%) and aviation services (3.4%), as well as increased earnings from several of our smaller
service businesses. The increase from TTI was primarily attributable to the increase in sales and higher average gross margin
rates, partially offset by unfavorable foreign currency effects in 2022 and a favorable legal settlement in 2021. The earnings
increase from aviation services was primarily attributable to improved product sales margins, increased training hours andlower restructuring costs at FlightSafety. Earnings from our smaller service businesses increased $106 million (19.3%) over
2021, reflecting a combination of higher revenues and operating cost leverage.

Manufacturing, Service and Retailing
Retailing
Our largest retailing business is Berkshire Hathaway Automotive, Inc. (“BHA”), which represented 67% of our combined
retailing revenue in 2023. BHA consists of over 80 auto dealerships that sell new and pre-owned automobiles and offer repair
services and related products. BHA also offers and insures vehicle service contracts and related insurance products. Ourretailing businesses also include four home furnishings businesses (Nebraska Furniture Mart, R.C. Willey, Star Furniture andJordan’s), which sell furniture, appliances, flooring and electronics. The home furnishings group represented 18% of the
combined retailing revenues in 2023.
Other retailing businesses include three jewelry businesses (Borsheims, Helzberg and Ben Bridge), See’s Candies(confectionary products), Pampered Chef (high quality kitchen tools), Oriental Trading Company (party supplies, schoolsupplies and toys and novelties) and Detlev Louis Motorrad (“Louis”), a retailer of motorcycle accessories based in Germany.
2023 versus 2022
Retailing group revenues increased $111 million (0.6%) in 2023 compared to 2022, reflecting an increase at BHA,
partially offset by lower revenues from our other retailers. BHA’s revenues increased 3.9% in 2023 compared to 2022.
Revenues from new vehicle sales increased 12.6% in 2023 compared to 2022, while revenues from pre-owned retail vehicle
sales declined 9.4%. Retail unit sales increased 2.7%, reflecting an 11.7% increase in new vehicles sold and a 4.7% decreasein pre-owned vehicles sold. Although new vehicle inventory levels remain well below historical levels, vehicle supply continues
to gradually rise. Revenues from BHA’s parts/service/repair operations increased 6.6% in 2023 versus 2022. Other retailingrevenues in the aggregate declined 5.6% in 2023 versus 2022, due primarily to an 8.6% decline in revenues at our homefurnishings businesses.
Retailing group pre-tax earnings were $1.7 billion in 2023, unchanged from 2022. BHA’s pre-tax earnings increased
17.7%, primarily due to earnings increases from the parts/service/repair and finance/service contract operations, as well as fromhigher investment income and lower operating and liability remeasurement expenses, partially offset by lower vehicle grossprofit margin rates and higher floor plan interest expense. BHA’s comparative vehicle gross profit margin rates peaked in mid2022 due to supply chain disruptions and have since declined. Aggregate pre-tax earnings for the remainder of our retailinggroup declined $168 million (21.8%) in 2023 compared to 2022, primarily due to a 28.3% decrease in home furnishingsbusinesses earnings and the impact of a gain in 2022 from the divestiture of certain jewelry stores.
2022 versus 2021
Retailing group revenues increased $337 million (1.8%) in 2022 compared to 2021, reflecting an increase at BHA,
partially offset by combined lower revenues from our other retailers. BHA’s revenues increased 6.1% in 2022 compared to2021. Revenues from new and used retail vehicle sales increased 5.9% compared to 2021, attributable to higher average vehicletransaction prices, partly offset by a 4.5% decline in total retail units sold. New vehicle unit sales in 2022 were constrained byrelatively low, but gradually rising, new vehicle supplies. Revenues from BHA’s parts/service/repair operations increased
11.1% versus 2021. Revenues of the home furnishings group declined 2.6%, while revenues of all other retailers declined 8.9%,
primarily due to lower sales at Pampered Chef.
Pre-tax earnings of the retailing group decreased $85 million (4.7%) in 2022 compared to 2021 and the pre-tax marginrate decreased 0.6 percentage points to 8.9%. BHA’s pre-tax earnings increased 18.4%, primarily due to increases in vehicle
gross profit margins attributable to low available inventory. BHA’s vehicle gross profit margin rates accelerated during thesecond half of 2021, peaked in the first half of 2022 and declined over the remainder of the year. Aggregate pre-tax earnings
for the remainder of the retailing group decreased $233 million (23.2%) in 2022 compared to 2021, primarily due to reduced
earnings from the home furnishings group, See’s Candies and Pampered Chef.

Management’s Discussion and Analysis
Manufacturing, Service and Retailing
McLaneMcLane Company, Inc. (“McLane”) operates a wholesale distribution business that provides grocery and non-foodconsumer products to retailers and convenience stores (“grocery”) and to restaurants (“foodservice”). McLane also operates
businesses that are wholesale distributors of distilled spirits, wine and beer (“beverage”). The grocery and foodservice
businesses generate high sales and very low profit margins. These businesses have several significant customers, including
Walmart, 7-Eleven, Yum! Brands and others. Grocery sales comprised 62% of McLane’s consolidated sales in 2023 withfoodservice comprising most of the remainder. A curtailment of purchasing by any of its significant customers could have an
adverse impact on periodic revenues and earnings.
2023 versus 2022
Revenues were $52.6 billion in 2023, a decline of $602 million (1.1%) compared to 2022. Revenues from the grocery
and foodservice businesses declined 0.8% and 2.2%, respectively, while revenues from the beverage business increased 1.9%
compared to 2022. Revenues of the grocery and the foodservice businesses were negatively affected in 2023 by lower unit
volumes.
Pre-tax earnings increased $184 million (67.9%) in 2023 compared to 2022. The increase reflected a slight increase in
the overall gross sales margin rate, increased other income and lower fuel expenses, partly offset by higher personnel expenses.
2022 versus 2021
Revenues were $53.2 billion in 2022, an increase of $3.8 billion (7.6%) compared to 2021. Revenues from the grocery
business increased 4.4%, while revenues from the foodservice and beverage businesses increased 14.1% and 6.0%,
respectively.
Pre-tax earnings increased $41 million (17.8%) in 2022 compared to 2021. The increase reflected slightly higher grossmargin rates in the grocery and foodservice businesses, partly offset by higher personnel costs, fuel expense and insurance
costs. McLane’s grocery and foodservice operating results were adversely affected by supply chain constraints, including theeffects of labor and truck driver shortages, high fuel costs and high inventory costs.
Non-Controlled Businesses
After-tax earnings of our non-controlled businesses include our proportionate share of earnings attributable to ourinvestments in Kraft Heinz, Occidental Petroleum (“Occidental”), PTC (through January 31, 2023) and Berkadia. After-tax
equity earnings attributable to these businesses increased $222 million in 2023 compared to 2022, primarily due to increased
earnings from Occidental. We adopted the equity method of accounting for our investment in Occidental common stock on
August 4, 2022. Equity method after-tax earnings increased $724 million in 2022 versus 2021, primarily due to higher earnings
from Kraft Heinz and PTC and from the inclusion of Occidental in 2022.
Our after-tax earnings from Kraft Heinz were $790 million in 2023, $550 million in 2022 and $317 million in 2021,
which included our after-tax share of goodwill and other intangible asset impairment charges recorded by Kraft Heinz of $126
million in 2023, $157 million in 2022 and $259 million in 2021. Occidental’s financial information is not available in time for
concurrent reporting in our Consolidated Financial Statements. Therefore, we report the equity method effects for Occidental
on a one-quarter lag. Our after-tax earnings from Occidental were $851 million in 2023 and $258 million in 2022. As of January
31, 2023, we discontinued using the equity method for our pre-existing 38.6% interest in PTC upon acquiring a controllinginterest in PTC. We began consolidating PTC’s financial statements in our Consolidated Financial Statements on February 1,
2023. See Notes 2 and 5 to the Consolidated Financial Statements. Our after-tax equity earnings from PTC decreased $559
million in 2023 compared to 2022 and increased $267 million in 2022 compared to 2021.

Unrealized gains and losses arising from changes in market prices of our investments in equity securities are included inour reported earnings, which significantly increases the volatility of our periodic net earnings due to the magnitude of ourequity securities portfolio and the inherent volatility of equity securities prices. Unrealized gains and losses also include theeffects of changes in foreign currency exchange rates on investments in non-U.S. issuers that are held by our U.S.-based
subsidiaries.
Pre-tax investment gains and losses included net unrealized gains of approximately $69.1 billion in 2023, losses ofapproximately $63.1 billion in 2022 and gains of approximately $76.4 billion in 2021 attributable to changes in market prices
of equity securities we held at the end of each year. We also recorded pre-tax gains and losses from market value changes
during each year on equity securities sold during such year, including gains of $2.7 billion in 2023, losses of $3.9 billion in
2022 and gains of $1.0 billion in 2021. Taxable investment gains on equity securities sold, which is generally the difference
between sales proceeds and the original cost basis of the securities sold, were $5.0 billion in 2023, $769 million in 2022 and$3.6 billion in 2021. Investment gains in 2023 included a non-cash pre-tax gain of approximately $3.0 billion related to theremeasurement of our pre-existing interest in PTC to fair value through the application of acquisition accounting upon attaining
control of PTC for financial reporting purposes.
We believe that investment gains and losses, whether realized from sales or unrealized from changes in market prices,
are often meaningless in terms of understanding our reported consolidated earnings or evaluating our periodic economic
performance. We continue to believe the investment gains and losses recorded in earnings in any given period has little
analytical or predictive value.
Derivative contract gains and losses in 2022 and 2021 pertained to our equity index put option contract liabilities.
Substantially all of our contracts are now expired and our exposure to loss in the future is insignificant.

After-tax acquisition accounting expenses include charges arising from the application of the acquisition method in
connection with certain of Berkshire’s business acquisitions. Such charges arise primarily from the amortization of intangible
assets recorded in connection with those business acquisitions.
Foreign currency exchange rate gains pertain to Berkshire’s and BHFC’s Euro, Great Britain Pound and Japanese Yen
denominated debt. Changes in foreign currency exchange rates produce unrealized gains and losses from the periodic
revaluation of these liabilities into U.S. Dollars. In each year, we recorded foreign currency exchange rate gains on these debt
issues due to strengthening of the U.S. Dollar, which reduced the U.S Dollar carrying value of the debt. The gains and losses
recorded in any given period can be significant due to the magnitude of the borrowings and the inherent volatility in foreign
currency exchange rates. Other earnings consist primarily of Berkshire parent company investment income, intercompany
interest income where the interest expense is included in earnings of the operating businesses, corporate expenses andunallocated income taxes. Investment income increased by $483 million in 2023 compared to 2022, primarily due to higher
interest rates in 2023.

Management’s Discussion and Analysis
Financial Condition
Our Consolidated Balance Sheet continues to reflect significant liquidity and a very strong capital base. Berkshire’s
shareholders’ equity at December 31, 2023 was $561.3 billion, an increase of $87.8 billion since December 31, 2022. Net
earnings attributable to Berkshire shareholders were $96.2 billion and included after-tax investment gains of approximately$58.9 billion. Over each of the last three years, investment gains and losses from changes in the market prices of our investmentsin equity securities produced significant volatility in our earnings.
Berkshire’s common stock repurchase program, as amended, permits Berkshire to repurchase its Class A and Class B
shares at prices below Berkshire’s intrinsic value, as conservatively determined by Warren Buffett, Berkshire’s Chairman of
the Board. The program does not specify a maximum number of shares to be repurchased and does not require any specified
repurchase amount. The program is expected to continue indefinitely. We will not repurchase our stock if it reduces the total
amount of our consolidated cash, cash equivalents and U.S. Treasury Bills holdings to below $30 billion. Financial strengthand redundant liquidity will always be of paramount importance at Berkshire. Berkshire paid $9.2 billion in 2023 to repurchaseshares of its Class A and B common stock.
At December 31, 2023, our insurance and other businesses held cash, cash equivalents and U.S. Treasury Bills of $163.3
billion, which included $133.4 billion invested in U.S. Treasury Bills. Investments in equity and fixed maturity securities(excluding our investments in Kraft Heinz and Occidental common stock) were $377.6 billion. During 2023, we paid cash of$16.5 billion to acquire equity securities and we received proceeds of $40.6 billion from sales of equity securities. On January
31, 2023, we acquired an additional 41.4% interest in PTC for approximately $8.2 billion. On January 16, 2024, we acquired
the remaining 20% ownership interest in PTC held by non-controlling shareholders for $2.6 billion.
Our consolidated borrowings at December 31, 2023 were $128.3 billion, of which over 95% were by the Berkshire parent
company, BHFC, and by BNSF, BHE, PTC and their subsidiaries. During 2023, we issued term debt of approximately $7.8
billion and paid approximately $11.3 billion of maturing term debt. Expected principal and interest payments related to ourconsolidated borrowings in each of the next five years are (in billions): $18.7 in 2024; $11.6 in 2025; $10.3 in 2026; $8.7 in
2027; and $10.4 in 2028.
Berkshire parent company debt outstanding at December 31, 2023 was $18.8 billion, a decrease of $2.6 billion from
December 31, 2022. In 2023, Berkshire issued an aggregate ¥286.4 billion (approximately $2.0 billion) of senior notes andrepaid approximately $4.3 billion of maturing senior notes. The carrying value of Berkshire parent company debt decreased$371 million in 2023 from changes in foreign currency exchange rates on its non-U.S. Dollar denominated debt.
Senior note borrowings of BHFC, a wholly-owned financing subsidiary, were approximately $18.0 billion at December
31, 2023, substantially unchanged from December 31, 2022. BHFC’s borrowings are used to fund a portion of loans originatedand acquired by Clayton Homes and equipment held for lease by our railcar leasing business. Berkshire guarantees BHFC’ssenior notes for the full and timely payment of principal and interest.
BNSF’s outstanding debt was $23.5 billion as of December 31, 2023, substantially unchanged from December 31, 2022.
During 2023, BNSF issued $1.6 billion of 5.2% debentures due in 2054 and repaid approximately $1.6 billion of term debt. In
2023, BHE subsidiaries issued $4.2 billion of term debt with a weighted average interest rate of 5.7% and maturity dates ranging
from 2033 to 2055 and repaid approximately $3.7 billion of term debt. In 2024, BHE subsidiaries issued $5.1 billion of term
debt with a weighted average interest rate of 5.4% and maturity dates ranging from 2029 to 2055 and repaid short term
borrowings of approximately $2.8 billion. Borrowings of PTC were $5.8 billion at December 31, 2023, relatively unchanged
since January 31, 2023. Berkshire does not guarantee the repayment of debt issued by BNSF, BHE, PTC or any of theirsubsidiaries or affiliates.
In each of the past three years, our diverse group of businesses generated net operating cash flows between $37 billion
and $49 billion. Our consolidated capital expenditures for property, plant and equipment and equipment held for lease were$19.4 billion in 2023, which included capital expenditures by BNSF and BHE of $13.1 billion. BNSF and BHE maintain verylarge investments in capital assets (property, plant and equipment) and regularly make significant capital expenditures in thenormal course of business. We forecast capital expenditures for BHE and BNSF in 2024 of approximately $14.3 billion. On
September 1, 2023, a BHE subsidiary acquired an additional 50% limited partner interest in its Cove Point LNG, LP subsidiary
for $3.3 billion.

Management’s Discussion and Analysis
Contractual Obligations
We are party to other contracts associated with ongoing business activities, which will result in cash payments tocounterparties in future periods. Our annual debt maturities for the next five years are summarized in Note 19 to theConsolidated Financial Statements. We also currently expect to pay interest on our debt of between $4 billion and $5 billion
per annum over the next five years. Certain other obligations are included in our Consolidated Balance Sheets, such as operatinglease liabilities and shared aircraft repurchase liabilities of NetJets. Estimated payments of these liabilities in each of the next
five years are (in billions): $1.9 in 2024; $1.7 in 2025; $1.5 in 2026; $1.8 in 2027; and $1.9 in 2028.
We are also obligated to pay claims arising from our property and casualty insurance companies. Such liabilities,
including amounts from retroactive reinsurance, were approximately $146 billion at December 31, 2023. We currently forecast
claim payments in 2024 of approximately $37 billion with respect to claims occurring prior to 2024. However, the timing andamount of the payments under insurance and reinsurance contracts are contingent upon the outcome of future events and canbe highly uncertain. Actual payments will likely vary, perhaps materially, from the forecasted payments. We anticipate thatthese payments will be funded by operating cash flows.
Other obligations pertaining to the acquisition of goods or services in the future, such as certain purchase obligations,
are not currently reflected in the Consolidated Financial Statements and will be recognized in future periods as the goods aredelivered or services are provided. As of December 31, 2023, the largest categories of our long-term contractual obligations
primarily related to fuel, capacity, transmission and maintenance contracts and capital expenditure commitments of BHE andBNSF, aircraft purchase commitments of NetJets and certain materials purchase commitments. We currently estimate future
payments associated with these contracts over the next five years will approximate $22 billion, including $10 billion in 2024.
Critical Accounting Estimates
Certain accounting policies require us to make estimates and judgments in determining the amounts reflected in our
Consolidated Financial Statements. Such estimates and judgments necessarily involve varying and possibly significant degrees
of uncertainty. Accordingly, certain amounts currently recorded in our Consolidated Financial Statements will likely be
adjusted in the future based on new available information and changes in other facts and circumstances. A discussion of ourprincipal accounting policies that required the application of significant judgments as of December 31, 2023 follows.
Property and casualty insurance unpaid losses
We record liabilities for unpaid losses and loss adjustment expenses (also referred to as “gross unpaid losses” or “claim
liabilities”) based upon estimates of the ultimate amounts payable for loss events occurring on or before the balance sheet date.
The timing and amount of ultimate loss payments are contingent upon, among other things, the timing of claim reporting frominsureds and ceding companies and the final determination of the loss amount through the loss adjustment and settlement
process.
As of the balance sheet date, recorded claim liabilities include estimates for reported claims and for incurred-but-notreported (“IBNR”) claims. The period between the loss occurrence date and loss settlement date is the “claim-tail.” Property
claims typically have relatively short claim-tails, while casualty claims usually have longer claim-tails, occasionally extendingfor decades. Casualty claims may be more susceptible to litigation and the impact of changing contract interpretations. The
legal environment and judicial process further contribute to extending claim-tails.
Our consolidated claim liabilities, including liabilities from retroactive reinsurance contracts, as of December 31, 2023
were approximately $146 billion, of which 76% related to GEICO and the Berkshire Hathaway Reinsurance Group. Additional
information regarding significant uncertainties inherent in the processes and techniques for estimating unpaid losses of thesebusinesses follows.

Property and casualty insurance unpaid losses
GEICO
GEICO predominantly writes private passenger automobile insurance. As of December 31, 2023, GEICO’s gross unpaid
losses were $24.4 billion and claim liabilities, net of reinsurance recoverable, were $23.4 billion. GEICO’s claim reserving
methodologies produce liability estimates based upon the individual claims. The key assumptions affecting our liability
estimates include projections of ultimate claim counts (“frequency”) and average loss per claim (“severity”). We utilize a
combination of several actuarial estimation methods, including Bornhuetter-Ferguson and chain-ladder methodologies.
Claim liability estimates for liability coverages (such as bodily injury (“BI”), uninsured motorists, and personal injury
protection) are more uncertain due to the longer claim-tails, so we establish additional case development estimates. As of
December 31, 2023, case development liabilities averaged approximately 28% of reported reserves. We select casedevelopment factors through analysis of the overall adequacy of historical case liabilities.
We test the adequacy of the aggregate claim liabilities using one or more actuarial projections based on claim closure
models and paid and incurred loss triangles. Each type of projection analyzes loss occurrence data for claims occurring in agiven period and projects the ultimate cost.
Our aggregate claim liability estimates recorded at the end of 2022 were reduced by $1.5 billion during 2023, which
produced a corresponding increase to pre-tax earnings. The assumptions used to estimate liabilities at December 31, 2023
reflect the most recent frequency and severity estimates. Future development of recorded liabilities will depend on whether
actual frequency and severity of claims are more or less than anticipated.
With respect to liabilities for BI claims, we believe it is reasonably possible that average claims severities will change
by at least one percentage point from the projected severities used in establishing the recorded liabilities at December 31, 2023.
We estimate that a one percentage point increase or decrease in BI severities would produce a $210 million increase or decrease
in recorded liabilities, with a corresponding decrease or increase in pre-tax earnings. Many of the economic forces that would
likely cause BI severity to differ from expectations would likely also cause severities for other injury coverages to differ in thesame direction.

49,318Gross unpaid losses and loss adjustment expenses consist primarily of traditional property and casualty coverages written
under excess-of-loss and quota-share treaties. Under certain contracts, coverage can apply to multiple lines of business written
and the ceding company may not report loss data by such lines consistently, if at all. In those instances, we judgmentally
allocate losses to property and casualty coverages based on internal estimates.
The nature, extent, timing and perceived reliability of loss information received from ceding companies varies widely
depending on the type of coverage and the contractual reporting terms. Reinsurance contract terms, conditions and coverages
also tend to lack standardization and may evolve more rapidly than primary insurance policies.

K-60

Management’s Discussion and Analysis
Critical Accounting Estimates
Property and casualty insurance unpaid losses
The loss information provided under many facultative (individual risk) or per occurrence excess contracts may becomparable to the information received under a primary insurance contract. However, loss information with respect toaggregate excess-of-loss and quota-share contracts is often in a summary form rather than on an individual claim basis. Lossdata includes currently recoverable paid losses, as well as case loss estimates. Ceding companies infrequently provide reliable
IBNR loss estimates.
Loss reporting to reinsurers is typically slower than primary insurers. In the U.S., client reporting is generally required
at quarterly intervals ranging from 30 to 90 days after the end of the quarterly period, while outside of the U.S., reinsurance
reporting practices may vary further, with some clients reporting annually ranging from 90 to 180 days after the end of theannual period. To the extent that reinsurers assume and cede underlying risks from other reinsurers, further delays in claims
reporting may occur. The relative impact of reporting delays on the reinsurer may vary depending on the type of coverage,
contractual reporting terms, the magnitude of the claim relative to the attachment point of the reinsurance coverage and otherreasons.
As reinsurers, the premium and loss data we receive is at least one level removed from the underlying claimant, so there
is a risk that the loss data reported is incomplete, inaccurate or the claim is outside the coverage terms. We maintain internal
procedures to determine that the information is complete and in compliance with the contract terms. Generally, our reinsurance
contracts permit us to access the ceding company’s records with respect to the subject business, thus providing the ability toaudit the reported information. In the normal course of business, disputes occasionally arise concerning whether claims arecovered by our reinsurance policies. We resolve most coverage disputes through negotiation with the client. If disputes cannot
be resolved, our contracts generally provide arbitration or alternative dispute resolution processes. We believe there are nocoverage disputes at this time for which an adverse resolution would likely have a material impact on our consolidated resultsof operations or financial condition.
Establishing claim liability estimates for reinsurance requires evaluation of loss information received from our clients.
We generally rely on the ceding companies’ reported case loss estimates. We independently evaluate certain reported caselosses and if appropriate, we use our own case liability estimate. For instance, as of December 31, 2023, our case loss estimates
exceeded ceding company estimates by approximately $575 million for certain legacy workers’ compensation claims occurring
over 10 years ago. We also periodically conduct detailed reviews of individual client claims, which may cause us to adjust ourcase estimates.
Although liabilities for losses are initially determined based on pricing and underwriting analysis, we use a variety ofactuarial methodologies that place reliance on the extrapolation of historical data, loss development patterns, industry data andother benchmarks. The estimate of the IBNR liabilities also requires judgment by actuaries and management to reflect the
impact of additional factors like change in business mix, volume, claim reporting and handling practices, inflation, social andlegal environment and the terms and conditions of the contracts. The methodologies generally fall into or are hybrids of one ormore of the following categories:
Paid and incurred loss development methods consider expected case loss emergence and development patterns, together
with expected loss ratios by year. Factors affecting our loss development analysis include, but are not limited to, changes in thefollowing: client claims reporting and settlement practices, the frequency of client company claim reviews, policy terms andcoverage (such as loss retention levels and occurrence and aggregate policy limits), loss trends and legal trends that result inunanticipated losses. Collectively, these factors influence our selections of expected case loss emergence patterns.
Incurred and paid loss Bornhuetter-Ferguson methods consider actual paid and incurred losses and expected reporting
patterns of paid and incurred losses, taking the initial expected ultimate losses into account to determine an estimate of the
expected unpaid or unreported losses.

K-61

Management’s Discussion and Analysis
Critical Accounting Estimates
Property and casualty insurance unpaid losses
Frequency and severity methods commonly focus on a review of the number of anticipated claims and the anticipatedclaims severity and may also rely on development patterns to derive such estimates. However, our processes and techniques
for estimating liabilities in such analyses generally rely more on a per-policy assessment of the ultimate cost associated with
the individual loss rather than with an analysis of historical development patterns of past losses.
Additional analysis – In some cases we have established reinsurance claim liabilities on a contract-by-contract basis,
determined from case loss estimates reported by the ceding company and IBNR liabilities that are primarily a function of an
anticipated loss ratio for the contract and the reported case loss estimate. Liabilities are adjusted upward or downward overtime to reflect case losses reported versus expected case losses, which we use to form revised judgment on the adequacy of the
expected loss ratio and the level of IBNR liabilities required for unreported claims. Anticipated loss ratios are also revised toinclude estimates of known major catastrophe events.
Our claim liability estimation process for short-tail lines, primarily property exposures, utilizes a combination of the paid
and incurred loss development methods and the incurred and paid loss Bornhuetter-Ferguson methods. Certain property
catastrophe, individual risk and aviation excess-of-loss contracts tend to generate low frequency/high severity losses. Our
processes and techniques for estimating liabilities under such contracts generally rely more on a per contract assessment of theultimate cost associated with the individual loss event rather than with an analysis of the historical development patterns ofpast losses.
For our long-tail lines, primarily casualty exposures, we may rely on different methods depending on the maturity of thebusiness, with estimates for the most recent years being based on priced loss expectations and more mature years reflecting thepaid or incurred development pattern indications.
In 2023, workers’ compensation claims reported losses were less than expected. As a result, we reduced estimatedultimate losses for prior years’ loss events by $116 million. We estimate that increases of ten percent in the tail of the expected
loss emergence pattern and in the expected loss ratios would produce a net increase of approximately $1.0 billion in IBNR
liabilities, producing a corresponding decrease in pre-tax earnings. We believe it is reasonably possible for these assumptions
to increase at these rates.
For other casualty losses, other than asbestos and environmental, we reduced estimated ultimate liabilities for prior years’
events by approximately $225 million in 2023. For certain significant casualty and general liability portfolios, we estimate that
increases of five percent in the claim-tails of the expected loss emergence patterns and in the expected loss ratios could produce
a net increase in our nominal IBNR liabilities and a corresponding reduction in pre-tax earnings of approximately $2 billion,
although outcomes of greater than or less than $2 billion are possible.
The change in estimated ultimate liabilities for asbestos and environmental claims, excluding amounts assumed underretroactive reinsurance contracts was not significant in 2023. Net liabilities for such claims were approximately $2.0 billion at
December 31, 2023. Loss estimations for these exposures are difficult to determine due to the changing legal environment andincreases may be required in the future if new exposures or claimants are identified, new claims are reported or new theories
of liability emerge.
Retroactive reinsurance
Our retroactive reinsurance contracts cover loss events occurring before the contract inception dates. Claim liabilities
associated with our retroactive reinsurance contracts predominately pertain to casualty or liability exposures. We expect theclaim-tails will be very long. At December 31, 2023, gross unpaid losses were $34.6 billion and deferred charges were $9.5
billion.
Our contracts are generally subject to maximum limits of indemnification and, as such, we currently expect thatmaximum remaining gross losses payable under our retroactive policies will not exceed $50 billion. Absent significant judicial
or legislative changes affecting asbestos, environmental or mass tort exposures, we also currently believe it unlikely that losses
will develop upward to the maximum losses payable or downward by more than 15% of our current estimated gross liability.

K-62

Management’s Discussion and Analysis
Critical Accounting Estimates
Property and casualty insurance unpaid losses
We establish liability estimates by individual contract, considering exposure and development trends, historical aggregate
loss payment patterns and project expected ultimate losses under various scenarios. We apply judgmental probability factors
to these scenarios to determine an expected outcome. We also monitor subsequent loss payment activity and ceding company
reports and other available information. We re-estimate ultimate losses when significant events or significant deviations fromexpectations are revealed.
Certain of our retroactive reinsurance contracts include asbestos, environmental and other mass tort claims. Our estimatedliabilities for asbestos and environmental exposures were approximately $12.2 billion at December 31, 2023. We do notconsistently receive reliable detailed underlying claims data from all ceding companies, particularly with respect to multi-line
or aggregate excess-of-loss policies. When possible, we conduct a detailed analysis of the underlying loss data to make anestimate of ultimate reinsured losses. When detailed loss information is unavailable, we may apply recent industry trends andprojections to aggregate client data. Judgments in these areas necessarily consider the stability of the legal and regulatoryenvironment under which we expect claims will be adjudicated. Legal reform and legislation could also have a significant
impact on our ultimate liabilities.
Deferred charges for retroactive reinsurance contracts, which at contract inception, represents the excess of the estimatedultimate liability for unpaid losses over premiums received. Deferred charges are subsequently charged to pre-tax earnings infuture periods based on the expected timing and amount of loss payments. We adjust deferred charge balances for the impact
of changes in the expected timing and ultimate amount of claim payments. Based on the contracts in effect as of December 31,
2023, we estimate that amortization expense in 2024 will approximate $900 million.
We increased estimated ultimate liabilities for prior years’ retroactive reinsurance contracts by $1.1 billion in the fourth
quarter of 2023, primarily for asbestos, environmental and other casualty exposures. This increase, net of related changes inunamortized deferred charges, produced an incremental pre-tax underwriting loss of approximately $650 million.
Other Critical Accounting Estimates
Our Consolidated Balance Sheet at December 31, 2023 includes goodwill of acquired businesses of $84.6 billion andindefinite-lived other intangible assets of $18.9 billion. We evaluate these assets for impairment annually in the fourth quarterand on an interim basis if the facts and circumstances lead us to believe that more likely than not there has been an impairment.
Goodwill and indefinite-lived intangible asset impairment reviews include determining the estimated fair values of ourreporting units and of indefinite-lived intangible assets. Several methods may be used to estimate fair values, including market
quotations, multiples of earnings and other valuation techniques. We primarily use discounted projected future earnings or cash
flow methods in determining fair values. The key assumptions and inputs used in such determinations may include forecasting
revenues and expenses, cash flows and capital expenditures, as well as an appropriate discount rate and other inputs. Significant
judgment by management is required in estimating the fair value of a reporting unit and in performing impairment reviews.
Due to the inherent subjectivity and uncertainty in forecasting future cash flows and earnings over long periods of time, actual
results may differ materially from the forecasts. If the carrying value of a reporting unit exceeds the estimated fair value of thereporting unit, then the excess, limited to the carrying amount of goodwill, is charged to earnings as an impairment loss. If thecarrying value of the indefinite-lived intangible asset exceeds fair value, the excess is charged to earnings as an impairment
loss.
As of December 31, 2023, we concluded it was more likely than not that goodwill recorded in our Consolidated Balance
Sheet was not impaired. The fair value estimates of reporting units are and will likely be significantly affected by assumptions
on the long-term effects of the COVID-19 pandemic on the reporting units businesses, as well as other assumptions concerning
the long-term economic performance of the reporting units, which we cannot reliably predict. Consequently, any fair value
estimates can be subject to wide variations.

Critical Accounting Estimates
Other Critical Accounting Estimates
In connection with the annual goodwill impairment review conducted in the fourth quarter of 2023, the estimated fairvalues of nine reporting units did not exceed our carrying values by at least 20%. These reporting units included Precision
Castparts Corp. (“PCC”) and three reporting units acquired in late 2022 and early 2023. Our estimated fair value of PCC wasapproximately $32.6 billion, exceeding our carrying value of approximately $29.7 billion by 10%. Our carrying value of PCC
included goodwill of approximately $7.5 billion. The three reporting units acquired in late 2022 and early 2023 included PTC,
Jazwares and IPS. The fair values of these entities at December 31, 2023 totaled approximately $21.5 billion, which exceeded
our carrying values by 1.5%. Goodwill associated with these reporting units was $8.5 billion. The remaining five other reporting
units had an aggregate estimated fair value of approximately $4.4 billion, which exceeded our aggregate carrying value ofapproximately 10%. The carrying value of these units included goodwill of approximately $1.3 billion.
Market Risk Disclosures
Our Consolidated Balance Sheets include substantial amounts of assets and liabilities whose fair values are subject tomarket risks. Our significant market risks are primarily associated with equity prices, interest rates, foreign currency exchange
rates and commodity prices. The fair values of our investment portfolios remain subject to considerable volatility. The following
sections address the significant market risks associated with our business activities.
Equity Price Risk
Investments in equity securities represent the most significant portion of our consolidated investment portfolio.
Strategically, we strive to invest in businesses that possess excellent economics and able and honest management, and we preferto invest a meaningful amount in each company. Historically, equity investments have been concentrated in relatively few
issuers. At December 31, 2023, approximately 79% of the total fair value of equity securities was concentrated in fivecompanies.
We often hold our equity securities for long periods and short-term price volatility has occurred in the past and will occur
in the future. We also strive to maintain significant levels of shareholder capital and ample liquidity to provide a margin ofsafety against short-term price volatility.
The following table summarizes our investments in equity securities, other than our investments in Kraft Heinz andOccidental common stocks, and the estimated effects of a hypothetical 30% increase and a 30% decrease in market prices asof those dates. The selected 30% hypothetical increase and decrease does not reflect the best or worst case scenario. Indeed,
results from declines could be far worse due both to the nature of equity markets and the aforementioned concentrations existingin our equity investment portfolio. Dollar amounts are in millions.

Management’s Discussion and Analysis
Interest Rate Risk
We also invest in bonds, loans or other interest rate sensitive instruments. Our strategy is to acquire or originate such
instruments at prices or with interest rates considered appropriate relative to the perceived credit risk. We also issue debt in theordinary course of business to fund business operations, business acquisitions and for other general purposes. We attempt tomaintain high credit ratings in order to minimize the cost of our debt. We generally do not utilize derivative products, such as
interest rate swaps, to manage interest rate risks and we do not attempt to match maturities of assets and liabilities.
The fair values of our fixed maturity investments, loans and finance receivables and notes payable and other borrowings
will fluctuate in response to changes in market interest rates. Increases and decreases in interest rates generally translate into
decreases and increases in fair values of these instruments. Additionally, fair values of interest rate sensitive instruments may
be affected by the creditworthiness of the issuer, prepayment options, relative values of alternative investments, the liquidityof the instrument and other general market conditions.
The following table summarizes the estimated effects of hypothetical changes in interest rates on our significant assets
and liabilities that are subject to significant interest rate risk. We assumed that the interest rate changes occur immediately anduniformly to each category of instrument and that there were no significant changes to other factors used to determine the valueof the instrument. The hypothetical changes in interest rates do not reflect the best or worst case scenarios. Actual results may
differ from those reflected in the table. Dollars are in millions.

Foreign Currency Risk
Our net assets subject to financial statement translation into U.S. Dollars are primarily in our insurance, utilities andenergy and certain manufacturing subsidiaries. A portion of our financial statement translation-related impact from changes inforeign currency rates is recorded in other comprehensive income. In addition, we include gains or losses from changes inforeign currency exchange rates in net earnings related to non-U.S. Dollar denominated assets and liabilities of Berkshire andits U.S.-based subsidiaries.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Shareholders and the Board of Directors ofBerkshire Hathaway Inc.
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of Berkshire Hathaway Inc. and subsidiaries (the “Company”)
as of December 31, 2023 and 2022, the related consolidated statements of earnings, comprehensive income, changes inshareholders’ equity, and cash flows, for each of the three years in the period ended December 31, 2023, and the related notes(collectively referred to as the “financial statements”). We also have audited the Company’s internal control over financial
reporting as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by
the Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of theCompany as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in
the period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States ofAmerica. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial
reporting as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by
COSO.
Change in Accounting Principle
As discussed in Note 1 to the financial statements, effective January 1, 2023, the Company adopted Accounting Standards
Update 2018-12 Targeted Improvements to the Accounting for Long-Duration Contracts, using the modified retrospective
approach.
Basis for Opinions
The Company’s management is responsible for these financial statements, for maintaining effective internal control overfinancial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in theaccompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion
on these financial statements and an opinion on the Company’s internal control over financial reporting based on our audits.
We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB)
and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and theapplicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and performthe audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due
to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the financial statements included performing procedures to assess the risks of material misstatement of thefinancial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures
included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also
included evaluating the accounting principles used and significant estimates made by management, as well as evaluating theoverall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an
understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing andevaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included
performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a
reasonable basis for our opinions.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding thereliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally
accepted accounting principles. A company’s internal control over financial reporting includes those policies and proceduresthat (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions anddispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts andexpenditures of the company are being made only in accordance with authorizations of management and directors of thecompany; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or
disposition of the company’s assets that could have a material effect on the financial statements.

K-67

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (Continued)
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also,
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Critical Audit Matters
The critical audit matters communicated below are matters arising from the current-period audit of the financial statements thatwere communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures thatare material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The
communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, andwe are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on
the accounts or disclosures to which they relate.
Unpaid Losses and Loss Adjustment Expenses — Refer to Notes 1 and 16 to the financial statements
Critical Audit Matter Description
The Company’s unpaid losses and loss adjustment expenses (“claim liabilities”) include short duration property and casualty
insurance and reinsurance contracts. Key assumptions affecting certain of these claim liabilities include anticipated claims andtheir severity, expected loss ratios, and expected patterns of paid and incurred losses.
Given the subjectivity of estimating these key assumptions, performing audit procedures to evaluate whether certain of theseclaim liabilities were appropriately recorded as of December 31, 2023 required a high degree of auditor judgment and anincreased extent of effort, including the need to involve our actuarial specialists.
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to the key assumptions affecting certain of these claim liabilities included the following, among
others:• We tested the operating effectiveness of controls over claim liabilities, including those over the key assumptions.
• We tested the underlying data that served as the basis for the actuarial analysis to evaluate that the inputs to the actuarial
estimate were accurate and complete.
• With the assistance of our actuarial specialists:• We developed independent estimates of the claim liabilities, including loss data and industry claim development
factors as needed, and compared our estimates to management’s estimates.
• We compared prior year estimates of expected incurred losses to actual experience during the most recent year to
identify potential bias in management’s determination of the claim liabilities.
Unpaid Losses and Loss Adjustment Expenses — Retroactive Reinsurance Contracts — Refer to Notes 1 and 17 to thefinancial statements
Critical Audit Matter Description
The Company’s unpaid losses and loss adjustment expenses under retroactive reinsurance contracts (“retroactive claim
liabilities”) include property and casualty retroactive reinsurance contracts. Key assumptions affecting certain of these
retroactive claim liabilities include anticipated claims and their severity, expected loss ratios, and expected patterns of paid andincurred losses.
Given the subjectivity of estimating these key assumptions, performing audit procedures to evaluate whether certain of theseclaim liabilities were appropriately recorded as of December 31, 2023, required a high degree of auditor judgment and anincreased extent of effort, including the need to involve our actuarial specialists.
How the Critical Audit Matter Was Addressed in the Audit

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (Continued)••

We tested the underlying data that served as the basis for the actuarial analysis, including historical claims, to test that the
inputs to the actuarial estimate were accurate and complete.
With the assistance of our actuarial specialists:• We developed independent claim liability estimates for certain retroactive reinsurance contracts and compared ourestimates to management’s estimates. For other retroactive reinsurance contracts, we evaluated the process used bymanagement to develop the estimated claim liabilities.
• We compared prior year estimates of expected incurred losses to actual experience during the most recent year to
identify potential bias in management’s determination of the claim liabilities.

Goodwill and Indefinite-Lived Intangible Assets — Refer to Notes 1 and 13 to the financial statements
Critical Audit Matter Description
The Company’s evaluation of goodwill and indefinite-lived intangible assets for impairment involves the comparison of thefair value of each reporting unit or asset to its carrying value. As of December 31, 2023, goodwill of approximately $8 billion
and indefinite-lived intangible assets of $13 billion were recorded at the Precision Castparts Corp. (“PCC”) reporting unit. PCC
primarily uses discounted projected future net earnings to estimate fair value, which requires management to make significant
estimates and assumptions related to forecasted future revenue, earnings before interest and taxes (“EBIT”), and discount rates.
Given the significant judgments made by management in their evaluation of potential impairment of PCC goodwill and PCC
indefinite-lived intangible assets and the difference between their fair values and carrying values, performing audit proceduresto evaluate the reasonableness of management’s estimates and assumptions required a high degree of auditor judgment.
Increased audit effort, including the need to involve our fair value specialists, was required to test management’s estimates andassumptions of forecasted future revenue and EBIT and the selection of the discount rate.
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to forecasts of future revenue and EBIT and the selection of the discount rate for the PCC reporting
unit and certain customer relationships included the following, among others:• We tested the effectiveness of controls over goodwill and indefinite-lived intangible assets, including those over theforecasts of future revenue and EBIT and the selection of the discount rate.
• We evaluated management’s ability to accurately forecast future revenue and EBIT by comparing prior year forecasts
to actual results in the respective years.
• We evaluated the reasonableness of management’s current revenue and EBIT forecasts by comparing the forecasts tohistorical results, newly executed long-term contracts, customer demand and build schedules, and forecasted
information included in analyst and industry reports and certain peer companies’ disclosures.
• With the assistance of our fair value specialists, we evaluated the valuation methodologies, the terminal growth rates
and discount rate, including testing the underlying source information and the mathematical accuracy of thecalculations, and developed a range of independent estimates and compared those to the terminal growth rates anddiscount rate selected by management.
• With the assistance of our fair value specialists, we evaluated the valuation methodologies, and the terminal growth
rates and discount rate. We tested the underlying source information and mathematical accuracy of calculations anddeveloped a range of independent estimates and compared those to the terminal growth rates and discount rate selectedby management.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2023
(1)

Significant accounting policies and practices(a)Nature of operations and basis of consolidation

Berkshire Hathaway Inc. (“Berkshire”) is a holding company owning subsidiaries engaged in numerous diverse
business activities, including insurance and reinsurance, freight rail transportation, utilities and energy, manufacturing,
service and retailing. In these notes the terms “us,” “we,” or “our” refer to Berkshire and its consolidated subsidiaries.
Further information regarding our reportable business segments is contained in Note 26. Information concerning
significant business acquisitions completed over the past three years appears in Note 2. We believe that reporting theRailroad, Utilities and Energy subsidiaries separately is appropriate given the relative significance of their long-lived
assets, capital expenditures and debt, which is not guaranteed by Berkshire.
The accompanying Consolidated Financial Statements include the accounts of Berkshire consolidated with theaccounts of all subsidiaries and affiliates in which we hold a controlling financial interest as of the financial statement
date. Normally a controlling financial interest reflects ownership of a majority of the voting interests. We consolidate
variable interest entities (“VIE”) when we possess both the power to direct the activities of the VIE that most significantly
affect its economic performance, and we (a) are obligated to absorb the losses that could be significant to the VIE or (b)hold the right to receive benefits from the VIE that could be significant to the VIE. Intercompany accounts andtransactions have been eliminated. Certain immaterial balances in the Consolidated Financial Statements have been
reclassified in prior years to conform to current year presentations.
(b)

Use of estimates in preparation of financial statements

We prepare our Consolidated Financial Statements in conformity with accounting principles generally accepted in
the United States (“GAAP”) which requires us to make estimates and assumptions that affect the reported amounts ofcertain assets and liabilities at the balance sheet date and the reported amounts of certain revenues and expenses during
the period. Our estimates of unpaid losses and loss adjustment expenses are subject to considerable estimation error due
to the inherent uncertainty in projecting ultimate claim costs. In addition, estimates and assumptions associated withdeterminations of deferred charges on retroactive reinsurance contracts, fair values of certain financial instruments andevaluations of goodwill and indefinite-lived intangible assets for impairment require considerable judgment. Actual
results may differ from the estimates used in preparing our Consolidated Financial Statements.
Our operating businesses have been impacted to varying degrees in recent years by government and private sector
actions to mitigate the adverse economic effects of the COVID-19 virus and its variants as well as by the developmentof geopolitical conflicts, supply chain disruptions and government actions to slow inflation. The economic effects fromthese events over longer terms cannot be reasonably estimated at this time. Accordingly, significant estimates used in
the preparation of our Consolidated Financial Statements, including those associated with evaluations of certain longlived assets, goodwill and other intangible assets for impairment, expected credit losses on amounts owed to us and theestimations of certain losses assumed under insurance and reinsurance contracts, may be subject to significant
adjustments in future periods.
(c)Cash and cash equivalents and short-term investments in U.S. Treasury Bills

Cash equivalents consist of demand deposit and money market accounts and investments with maturities of threemonths or less when purchased. Short-term investments in U.S. Treasury Bills have maturities exceeding three months
and less than one year at the time of purchase.
(d)Investments in fixed maturity securities

We classify investments in fixed maturity securities on the acquisition date and at each balance sheet date.
Securities classified as held-to-maturity are carried at amortized cost, reflecting the ability and intent to hold the securities
to maturity. Securities classified as trading are acquired with the intent to sell in the near term and are carried at fair value
with changes in fair value reported in earnings. All other securities are classified as available-for-sale and are carried atfair value. Our investments in fixed maturity securities are classified as available-for-sale. We amortize the difference
between the original cost and maturity value of a fixed maturity security to earnings using the interest method.

K-75

Notes to Consolidated Financial Statements(1)

Significant accounting policies and practices(d)Investments in fixed maturity securities

We record investment gains and losses on available-for-sale fixed maturity securities in earnings when the
securities are sold. For securities in an unrealized loss position, we recognize a loss in earnings for the excess of amortizedcost over fair value if we intend to sell before the price recovers. As of the balance sheet date, we evaluate whether theother unrealized losses are attributable to credit losses or other factors. We consider the severity of the decline in value,creditworthiness of the issuer and other relevant factors. We record an allowance for credit losses, limited to the excess
of amortized cost over fair value, with a corresponding charge to earnings if the present value of estimated expected cash
flows is less than the present value of contractual cash flows. The allowance may be subsequently increased or decreased
based on the prevailing facts and circumstances. The portion of the unrealized loss that we believe is not related to acredit loss is recognized in other comprehensive income.
(e)

Investments in equity securities

We carry investments in equity securities at fair value and record the changes in fair values in the Consolidated
Statements of Earnings as a component of investment gains and losses.
(f)

Investments under the equity method

We utilize the equity method to account for investments when we possess the ability to exercise significant
influence, but not control, over the operating and financial policies of the investee. The ability to exercise significant
influence is presumed when the investor possesses more than 20% of the voting interests of the investee. This
presumption may be overcome based on specific facts and circumstances that demonstrate that the ability to exercise
significant influence is restricted. We apply the equity method to investments in common stock and other investments
when such investments possess substantially identical subordinated interests to common stock, and do not apply theequity method to investments that are not in-substance common stock as defined by GAAP.
In applying the equity method, we record the investment at cost and subsequently increase or decrease the carrying
amount of the investment by our proportionate share of the net earnings or losses and other comprehensive income of
the investee. We record dividends or other equity distributions as reductions in the carrying value of the investment. If
net losses reduce our carrying amount to zero, additional net losses may be recorded if other investments in the investee
are at-risk, even if we have not committed to provide financial support to the investee. Such additional equity method
losses are based upon the change in our claim on the investee’s book value.
(g)Loans and finance receivables

Loans and finance receivables are primarily manufactured home loans, and to a lesser extent, commercial loans
and site-built home loans. We carry substantially all loans and finance receivables at amortized cost, net of allowancesfor expected credit losses, based on our ability and intent to hold such loans to maturity. Acquisition costs and loan
origination and commitment costs paid and fees received, as well as acquisition premiums or discounts, are amortized toinvestment income as yield adjustments over the lives of the loans.
Measurements of expected credit losses include provisions for non-collection, whether the risk is probable orremote. Expected credit losses on manufactured home loans are based on the net present value of future principal
payments less estimated expenses related to the charge-off and foreclosure of expected uncollectible loans and include
provisions for loans that are not in foreclosure. Our principal credit quality indicator is whether the loans are performing.
Expected credit loss estimates consider historical default rates, collateral recovery rates, historical runoff rates, interest
rates, reductions of future cash flows for modified loans and the historical time elapsed from last payment until
foreclosure, among other factors. In addition, our estimates consider current conditions and reasonable and supportable
forecasts.
Loans are considered delinquent when payments are more than 30 days past due. We place loans over 90 days pastdue on nonaccrual status and accrued but uncollected interest is reversed. Subsequent collections on the loans are first
applied to the principal and interest owed for the most delinquent amount. We resume interest income accrual once aloan is less than 90 days delinquent.

K-76

Notes to Consolidated Financial Statements(1)

Significant accounting policies and practices(g)Loans and finance receivables

Loans are considered non-performing when the foreclosure process has started. Once a loan is in the process offoreclosure, interest income is not recognized until the foreclosure is cured or the loan is modified. Once a modificationis complete, interest income is recognized based on the terms of the new loan. Foreclosed loans are charged off when thecollateral is sold. Loans not in foreclosure are evaluated for charge-off based on individual circumstances concerning thefuture collectability of the loan and the condition of the collateral securing the loan.
(h)Other receivables

Other receivables include balances due from customers, insurance premiums receivable and reinsurance losses
recoverable, as well as other receivables. Trade receivables, insurance premiums receivables and other receivables areprimarily short-term in nature with stated collection terms of less than one year from the date of origination. Reinsurance
recoverables are comprised of amounts ceded under reinsurance contracts or pursuant to mandatory governmentsponsored insurance programs. Reinsurance recoverables relate to unpaid losses and loss adjustment expenses arisingfrom property and casualty contracts and benefits under life and health contracts. Receivables are stated net of estimatedallowances for uncollectible balances.
We measure expected credit losses primarily utilizing credit loss history. In addition, our credit loss estimatesconsider current conditions and reasonable and supportable forecasts. In evaluating expected credit losses of reinsurance
recoverables on unpaid losses, we review the credit quality of the counterparty and consider right-of-offset provisions
within reinsurance contracts and other forms of credit enhancement including collateral, guarantees and other available
information. We charge off receivables against the allowances after reasonable collection efforts are exhausted.
(i)

Derivatives

We carry assets and liabilities arising from derivative contracts at fair value in other assets and accounts payable,
accruals and other liabilities in our Consolidated Balance Sheets. Balances are net of reductions permitted under masternetting agreements with counterparties. We record the changes in fair value of derivative contracts that do not qualify as
hedging instruments for financial reporting purposes in earnings or, if such contracts involve our regulated utilities
subsidiaries, as regulatory assets or liabilities when inclusion in regulated rates is probable.
(j)Fair value measurements

As defined under GAAP, fair value is the price that would be received to sell an asset or paid to transfer a liability
between market participants in the principal market or in the most advantageous market when no principal market exists.
Adjustments to transaction prices or quoted market prices may be required in illiquid or disorderly markets whenestimating fair value. In such circumstances, alternative valuation techniques may be appropriate to determine the valuethat would be received to sell an asset or paid to transfer a liability in an orderly transaction. Market participants are
assumed to be independent, knowledgeable, and able and willing to transact an exchange and not acting under duress.
Our nonperformance or credit risk is considered in determining the fair value of liabilities. Considerable judgment may
be required in interpreting market data used to develop the estimates of fair value. Accordingly, estimates of fair value
presented herein are not necessarily indicative of the amounts that could be realized in a current or future market
exchange.
(k)Inventories

Inventories consist of manufactured goods, goods or products acquired for resale and homes constructed for sale.
Manufactured inventory costs include materials, direct and indirect labor and factory overhead. At December 31, 2023,
we used the last-in-first-out (“LIFO”) method to value approximately 30% of consolidated inventories with the remainder
primarily determined under first-in-first-out and average cost methods. Non-LIFO inventories are stated at the lower ofcost or net realizable value. The excess of current or replacement costs over costs determined under LIFO wasapproximately $2.3 billion as of December 31, 2023 and $2.5 billion as of December 31, 2022.

K-77

Notes to Consolidated Financial Statements(1)

Significant accounting policies and practices(l)Property, plant and equipment and equipment held for lease

We use property, plant and equipment in our operations. We also own equipment that we lease to others underlease contracts. We record additions to such property at cost, which includes asset additions, improvements andbetterments. With respect to constructed assets, all materials, direct labor and contract services as well as certain indirect
costs are capitalized. Indirect costs include interest over the construction period. With respect to constructed assets ofour utility and energy subsidiaries that are subject to authoritative guidance for regulated operations, capitalized costs
also include an allowance for funds used during construction, which represents the cost of equity funds used to financethe construction of the regulated facilities. Normal repairs and maintenance and other costs that do not improve theproperty, extend its useful life or otherwise do not meet capitalization criteria are charged to expense as incurred.
Depreciation of assets of our regulated utilities and railroad is generally determined using group depreciation
methods where rates are based on periodic depreciation studies approved by the applicable regulator. Under groupdepreciation, a composite rate is applied to the gross investment in a particular class of property, despite differences inthe service life or salvage value of individual property units within the same class. When such assets are retired or sold,no gain or loss is recognized. Gains or losses on disposals of all other assets are recorded through earnings.
Ranges of estimated useful lives of depreciable assets unique to our railroad business are as follows: track structure
and other roadway – 10 to 100 years and locomotives, freight cars and other equipment – 6 to 45 years. Ranges of
estimated useful lives of assets unique to our utilities and energy businesses are as follows: utility generation,transmission and distribution systems – 5 to 80 years, interstate natural gas pipeline assets – 3 to 80 years, independent
power plants and other assets – 2 to 50 years, buildings and improvements – 10 to 30 years and machinery, equipment
and other – 3 to 10 years. We depreciate property, plant and equipment used by our other businesses to the estimatedsalvage value primarily using the straight-line method over estimated service lives. Ranges of estimated service lives ofdepreciable assets used in our other businesses are as follows: buildings and improvements – 5 to 50 years, machineryand equipment – 3 to 25 years and furniture, fixtures and other – 3 to 15 years. We depreciate the equipment held forlease to estimated salvage value primarily using the straight-line method over estimated useful lives ranging from 3 to
35 years. We use declining balance depreciation methods for assets when the revenue-earning power of the asset isgreater during the earlier years of its life.
We evaluate property, plant and equipment and equipment held for lease for impairment when events or changes
in circumstances indicate that the carrying value of such assets may not be recoverable or when the assets are held forsale. Upon the occurrence of a triggering event, we assess whether the estimated undiscounted cash flows expected fromthe use of the asset and the residual value from the ultimate disposal of the asset exceeds the carrying value. If thecarrying value exceeds the estimated recoverable amounts, we reduce the carrying value to fair value and record an
impairment loss in earnings, except with respect to impairment of assets of our regulated utility and energy subsidiaries
where the impacts of regulation are considered in evaluating the carrying value.
(m)

LeasesWe are party to contracts where we lease property from others. When we lease assets from others, we record rightof-use assets and lease liabilities. Right-of-use assets represent our right to use an underlying asset for the lease term andlease liabilities represent our obligation to make lease payments arising from the lease. In this regard, lease payments
include fixed payments and variable payments that depend on an index or rate. The lease term is considered the noncancellable lease period. Certain lease contracts contain renewal options or other terms that provide for variable payments
based on performance or usage. Options are not included in determining right-of-use assets or lease liabilities unless it
is reasonably certain that options will be exercised. Generally, incremental borrowing rates are used in measuring leaseliabilities. Right-of-use assets are subject to review for impairment. As permitted under GAAP, for some leases we donot separate lease components from non-lease components by class of asset and we do not record assets or liabilities forleases with terms of one year or less.
(n)

Goodwill and other intangible assets

Goodwill represents the excess of the acquisition price of a business over the acquisition date values of identified
net assets of that business. We evaluate goodwill for impairment at least annually. When evaluating goodwill for
impairment, we estimate the fair value of the reporting unit. Several methods may be used to estimate a reporting unit’s
fair value, including market quotations, asset and liability fair values and other valuation techniques, including, but notlimited to, discounted projected future net earnings or net cash flows and multiples of earnings. When the carrying
amount of a reporting unit, including goodwill, exceeds the estimated fair value, the excess up to the balance of goodwill
is charged to earnings as an impairment loss.
K-78

Notes to Consolidated Financial Statements(1)

Significant accounting policies and practices(n)Goodwill and other intangible assets

Intangible assets with indefinite lives are also tested for impairment at least annually and when events or changes
in circumstances indicate that, more-likely-than-not, the asset is impaired. Significant judgment is required in estimating
fair values and performing goodwill and indefinite-lived intangible asset impairment tests. We amortize intangible assets
with finite lives in a pattern that reflects the expected consumption of related economic benefits or on a straight-line basis
over the estimated economic useful lives. Intangible assets with finite lives are reviewed for impairment when events orchanges in circumstances indicate that the carrying amount may not be recoverable.
(o)

Revenue recognition

We earn insurance premiums on prospective property/casualty insurance and reinsurance contracts over the loss
exposure or coverage period in proportion to the level of protection provided. We earn premiums, in most cases, ratably
over the term of the contract with unearned premiums computed on a monthly or daily pro-rata basis. Premiums on
retroactive property/casualty reinsurance contracts are normally received in full and are fully earned at the inception of
the contracts, as all underlying loss events covered by the policies occurred prior to contract inception. Premiums for life
reinsurance and periodic payment annuity contracts are earned when due. Premiums for periodic payment annuity
contracts are fully received and earned at the inception of the contracts. Premiums earned are stated net of amounts ceded
to reinsurers. Premiums earned on contracts with experience-rating provisions reflect estimated loss experience undersuch contracts.
Sales and service revenues are recognized when goods or services are transferred to a customer. A good or service
is transferred when (or as) the customer obtains control of that good or service. Revenues are based on the consideration
we expect to receive in connection with our promises to deliver goods and services to our customers.
We manufacture and/or distribute a wide variety of industrial, building and consumer products. Our sales contracts
provide customers with products directly or through wholesale and retail channels in exchange for consideration specified
under the contracts. Contracts generally represent customer orders for individual products at stated prices. Sales contracts
may contain either single or multiple performance obligations. In instances where contracts contain multiple performanceobligations, we allocate the revenue to each obligation based on the relative stand-alone selling prices of each product orservice.
Sales revenues reflect reductions for returns, allowances, late delivery penalties, volume discounts and otherincentives, some of which may be contingent on future events. In certain customer contracts, sales revenues include
certain state and local excise taxes billed to customers on specified products when those taxes are levied directly upon
us by the taxing authorities. Sales revenues exclude sales taxes and value-added taxes collected on behalf of taxing
authorities. Sales revenues include consideration for shipping and other fulfillment activities performed prior to thecustomer obtaining control of the goods. We also elect to treat consideration for such services performed after control
has passed to the customer as sales revenue.
Product sales revenues are generally recognized at a point in time when control of the product transfers to thecustomer, which coincides with customer pickup or product delivery or acceptance, depending on terms of thearrangement. We recognize sales revenues and related costs with respect to certain contracts over time, relating to certain
bridge and structural steel, castings, forgings and aerostructures contracts. Control of the product units under thesecontracts transfers continuously to the customer as the product is manufactured. These products generally have noalternative use and the contract requires the customer to provide reasonable compensation if terminated for reasons otherthan breach of contract.
The primary performance obligation under our freight rail transportation service contracts is to move freight froma point of origin to a point of destination. The performance obligations are represented by bills of lading which create aseries of distinct services that have a similar pattern of transfer to the customer. The revenues for each performanceobligation are based on various factors including the product being shipped, the origin and destination pair and contract
incentives, which are outlined in various private rate agreements, common carrier public tariffs, interline foreign roadagreements and pricing quotes. The transaction price is generally a per car/unit amount to transport railcars from a
specified origin to a specified destination. Freight revenues are recognized over time as the service is performed because
the customer simultaneously receives and consumes the benefits of the service. Revenues recognized represent the
portion of the service completed as of the balance sheet date. Invoices for freight transportation services are generally
issued to customers and paid within 30 days or less. Customer incentives, which are primarily provided for shipping a
specified cumulative volume or shipping to/from specific locations, are recorded as a reduction to revenue on a pro-ratabasis based on actual or projected future customer shipments.
K-79

Notes to Consolidated Financial Statements(1)

Significant accounting policies and practices(o)Revenue recognition

Utilities and energy revenues derive primarily from regulated electricity and natural gas sales and sales of fuel.
Regulated electricity and natural gas revenues are primarily tariff-based sales arrangements approved by various
regulatory commissions. These tariff-based revenues are mainly comprised of energy, transmission, distribution andnatural gas and have performance obligations to deliver energy products and services to customers which are satisfied
over time as energy is delivered or services are provided. Such revenues are equivalent to the amounts we have the rightto invoice and correspond directly with the value to the customer of the performance to date and include billed andunbilled amounts. Payments from customers are generally due within 30 days of billing. Rates charged for regulated
energy products and services are established by regulators or contractual arrangements that establish the transaction
price, as well as the allocation of price among the separate performance obligations. When preliminary regulated rates
are permitted to be billed prior to final approval by the applicable regulator, certain revenue collected may be subject torefund and a liability for estimated refunds is accrued. Nonregulated energy revenues include fuel sales, and to a lesser
extent, renewable energy and other products. Fuels sold include diesel, gasoline and related products sold on a retail andwholesale basis. Fuel sales are recognized at the point-in-time when the product is delivered, and control is transferredto the customer, and include related excise taxes.
Other service revenues derive from contracts with customers in which performance obligations are satisfied overtime, where customers receive and consume benefits as we perform the services or at a point in time when the services
are completed. Other service revenues primarily derive from real estate brokerage, automotive repair, aircraft
management, aviation training, franchising activities and news distribution.
Leasing revenue is generally recognized ratably over the term of the lease or based on usage, if applicable under
the terms of the contract. A substantial portion of our lessor contracts are classified as operating leases.
(p)

Losses and loss adjustment expenses

We record liabilities for unpaid losses and loss adjustment expenses under property/casualty insurance andreinsurance contracts for loss events that have occurred on or before the balance sheet date. Such liabilities represent theestimated ultimate payment amounts without discounting for time value.
We base liability estimates on (1) loss reports from policyholders and cedents, (2) individual case estimates and(3) estimates of incurred but not reported losses. Losses and loss adjustment expenses in the Consolidated Statements ofEarnings include paid claims, claim settlement costs and changes in estimated claim liabilities. Losses and loss
adjustment expenses in the Consolidated Statements of Earnings are stated net of amounts recovered and estimates ofamounts recoverable under ceded reinsurance contracts. Reinsurance contracts do not relieve the ceding company of its
obligations to indemnify policyholders with respect to the underlying insurance and reinsurance contracts.
(q)

Retroactive reinsurance contracts

We record liabilities for unpaid losses and loss adjustment expenses under short duration retroactive reinsurance
contracts consistent with property/casualty insurance and reinsurance contracts described in Note 1(p). With respect toretroactive reinsurance contracts, we also record deferred charge assets at the inception of the contracts, representing theexcess, if any, of the estimated ultimate claim liabilities over the premiums earned. We subsequently amortize thedeferred charge assets over the expected claim settlement periods using the interest method. Changes to the estimatedtiming or amount of future loss payments also produce changes in deferred charge assets. We apply changes in such
estimates retrospectively and the resulting changes in deferred charge assets, together with periodic amortization, areincluded in insurance losses and loss adjustment expenses in the Consolidated Statements of Earnings.
(r)Insurance policy acquisition costs

We capitalize the direct incremental costs that relate to the successful sale of insurance contracts, subject toultimate recoverability. Direct incremental acquisition costs include commissions, premium taxes and certain other costs
associated with successful efforts. We expense all other underwriting costs as incurred. For short duration property andcasualty insurance contracts, we amortize deferred policy acquisition costs over the contract term as the related premiums
are earned. For long-duration life and health insurance contracts, we amortize deferred policy acquisition costs at aconstant level based on the expected amount of insurance in-force and the expected term of the contract using theassumptions consistent with those used in determining related insurance liabilities. Deferred policy acquisition costs areincluded in other assets and were approximately $4.6 billion and $3.8 billion at December 31, 2023 and 2022,
respectively, of which $3.9 billion and $3.2 billion, respectively, related to property and casualty insurance contracts.

Significant accounting policies and practices(s)Life, annuity and health insurance benefits

Liabilities for life, annuity and health insurance benefits under long-duration insurance contracts represent thepresent value of expected future cash outflows from future benefit payments and non-acquisition variable expenses, lessthe present value of expected future “net premiums” which is the portion of gross premiums required to provide for all
expected future benefits and variable expenses. Periodic payment and annuity reinsurance contracts are regarded aslimited payment contracts under GAAP. Such liabilities include the present value of expected future payments based on
the discount rates used to measure benefit liabilities and a deferred profit liability, representing the unamortized excess
of gross premiums received over the net premiums established at the inception of the contract.
In estimating future cash flows, we consider the timing and amount of future claims, premiums and expenses,
which require estimates of future investment yields, expected mortality, morbidity and lapse rates. Cash flow
assumptions are reviewed at least annually, with the effects of assumption changes recorded in earnings. The discountrate assumptions used to measure benefit liabilities are revised each reporting period based on the prevailing uppermedium grade corporate bond yields (generally single-A rated credit ratings) that reflect the duration characteristics andcurrency attributes of the liabilities. In measuring benefit liabilities, we generally group contracts by contract issue year.
The effects of changes in discount rates are recorded in other comprehensive income.
(t)Regulated utilities and energy businesses

Certain energy subsidiaries prepare their financial statements in accordance with authoritative guidance forregulated operations, reflecting the economic effects of regulation from the ability to recover certain costs from customers
and the requirement to return revenues to customers in the future through the regulated rate-setting process. Accordingly,
certain costs are deferred as regulatory assets and certain income is accrued as regulatory liabilities.
Regulatory assets and liabilities will be amortized into operating expenses and revenues over various future
periods. Regulatory assets and liabilities are continually assessed for probable future inclusion in regulatory rates byconsidering factors such as applicable regulatory or legislative changes and recent rate orders received by other regulated
entities. If future inclusion in regulatory rates ceases to be probable, the amount no longer probable of inclusion in
regulatory rates is charged or credited to earnings (or other comprehensive income, if applicable) or returned tocustomers.
(u)Foreign currency

The accounts of certain subsidiaries are measured using functional currencies other than the U.S. Dollar. Revenues
and expenses in the financial statements of these subsidiaries are translated into U.S. Dollars at the average exchange
rate for the period and assets and liabilities are translated at the exchange rate as of the end of the reporting period. The
net effects of translating the financial statements of these subsidiaries are included in shareholders’ equity as a componentof accumulated other comprehensive income. Gains and losses arising from transactions denominated in a currency otherthan the functional currency of the entity, including gains and losses from the remeasurement of assets and liabilities due
to changes in currency exchange rates, are included in earnings.
(v)

Income taxes

Berkshire files a consolidated federal income tax return in the U.S., which includes eligible subsidiaries. In
addition, we file income tax returns in U.S. state and local and in foreign jurisdictions. Provisions for current income tax
liabilities are calculated and accrued on income and expense amounts expected to be included in the income tax returns
for the current year. Income taxes reported in earnings also include deferred income tax provisions.
Deferred income tax assets and liabilities are computed on differences between the financial statement bases andtax bases of assets and liabilities at the enacted tax rates. Changes in deferred income tax assets and liabilities associatedwith components of other comprehensive income are charged or credited directly to other comprehensive income.
Otherwise, changes in deferred income tax assets and liabilities are included as a component of income tax expense. The
effect on deferred income tax assets and liabilities attributable to changes in enacted tax rates are charged or credited toincome tax expense in the period of enactment. Valuation allowances are established for certain deferred income tax
assets when realization is not likely.
Liabilities are established for uncertain tax positions taken or positions expected to be taken in income tax returns
when such positions, in our judgment, do not meet a more-likely-than-not threshold based on the technical merits of thepositions. Estimated interest and penalties related to uncertain tax positions are included as a component of income tax
expense.

Accounting pronouncement adopted in 2023

We adopted Accounting Standards Update 2018-12, “Targeted Improvements to the Accounting for LongDuration Contracts” (“ASU 2018-12”), as of January 1, 2023, which modified the accounting, reporting and disclosuresrelated to our long-duration insurance contracts. See Note 1(s). ASU 2018-12 was applied retrospectively as of January
1, 2021 (the “transition date”) to contracts in-force as of the transition date. As of the transition date, the after-tax impact
of changes in cash flow assumptions were recorded in retained earnings and the after-tax effect of changes in discountrate assumptions were recorded in accumulated other comprehensive income.
Certain items in the accompanying Consolidated Financial Statements in 2022 and 2021 were revised in connection
with the retrospective adoption. The revisions in 2022 and 2021 were primarily attributable to the effects of discount ratechanges, which were recorded in accumulated other comprehensive income, and are shown in the accompanying
Consolidated Statements of Comprehensive Income and Statements of Changes in Shareholders’ Equity. We also
increased previously reported net earnings attributable to Berkshire Hathaway shareholders by $142 million in 2021 and$60 million in 2022. We believe such effects are immaterial to our Consolidated Financial statements.

Accounting pronouncements to be adopted subsequent to December 31, 2023

In March 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 202302, “Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method” (“ASU 202302”). ASU 2023-02 permits reporting entities to elect to account for tax equity investments from which the income tax
credits are received using the proportional amortization method at the program level if certain conditions are met.
Currently, the proportional amortization method is limited to certain affordable housing tax credit investments. ASU
2023-02 is effective for fiscal years beginning after December 15, 2023. We believe that the adoption of ASU 2023-02
will not have a material effect on our Consolidated Financial Statements.
In November 2023, the FASB issued Accounting Standards Update 2023-07, “Improvements to Reportable
Segment Disclosures” (“ASU 2023-07”), which requires disclosures of significant expenses by segment and interim
disclosure of items that were previously required on an annual basis. ASU 2023-07 is to be applied on a retrospective
basis and is effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning
after December 15, 2024. We are evaluating the impact of ASU 2023-07 on disclosures in our Consolidated Financial
Statements.
In December 2023, the FASB issued Accounting Standards Update 2023-09, “Improvements to Income Tax
Disclosures” (“ASU 2023-09”), which provides for additional disclosures primarily related to the income tax rate
reconciliations and income taxes paid. ASU 2023-09 requires entities to annually disclose the income tax rate
reconciliation using both amounts and percentages, considering several categories of reconciling items, including stateand local income taxes, foreign tax effects, tax credits and nontaxable or nondeductible items, among others. Disclosureof the reconciling items is subject to a quantitative threshold and disaggregation by nature and jurisdiction. ASU 202309 also requires entities to disclose net income taxes paid or received to federal, state and foreign jurisdictions, as well
as by individual jurisdiction, subject to a five percent quantitative threshold. ASU 2023-09 may be adopted on aprospective or retrospective basis and is effective for fiscal years beginning after December 15, 2024 with early adoption
permitted. We are evaluating the impact of ASU 2023-09 on disclosures in our Consolidated Financial Statements.

Significant business acquisitions

Our long-held acquisition strategy is to acquire businesses that have consistent earning power, good returns on equity
and able and honest management. Financial results attributable to business acquisitions are included in our Consolidated
Financial Statements beginning on their respective acquisition dates.
On January 31, 2023, we acquired an additional 41.4% interest in Pilot Travel Centers, LLC (“PTC”) for approximately$8.2 billion. The acquisition increased our interest to 80%, representing a controlling interest in PTC for financial reporting
purposes as of that date. We began consolidating PTC’s financial statements in our Consolidated Financial Statements on
February 1, 2023. Since PTC’s most significant business activities involve purchasing and selling fuel (energy) on a wholesale
and retail basis, and other energy-related businesses, we include PTC within the railroad, utilities and energy sections of our
Consolidated Balance Sheet and Consolidated Statement of Earnings beginning February 1, 2023. We previously owned a
38.6% interest in PTC, which we accounted for under the equity method through the end of January 2023.
PTC operates more than 650 travel center and 75 fuel-only locations across 44 U.S. states and five Canadian provinces,primarily under the names Pilot or Flying J, as well as large wholesale fuel and fuel marketing businesses in the U.S. PTC also
sells diesel fuel at other locations in the U.S. and Canada through various arrangements with third party travel centers andoperates a water disposal business in the oil fields sector. PTC’s revenues and net earnings attributable to Berkshire shareholders
for the eleven months ending December 31, 2023 were $51.7 billion and $603 million, respectively. In applying the acquisition
method of accounting, we remeasured our previously held 38.6% investment in PTC to fair value and recognized a one-time,
non-cash remeasurement gain of approximately $3.0 billion, representing the excess of the fair value of that interest over the
carrying value under the equity method. In addition, we valued the noncontrolling interests at fair value as of January 31, 2023.
Pilot Corporation, the holder of the remaining noncontrolling interests in PTC, had an annual option to require us toredeem for cash all or a portion of its interests beginning in 2024. The redemption price was to be based on a multiple of PTC’s
earnings for the preceding year, with specified other adjustments, including the amount of PTC’s net debt. Pilot Corporation
filed a lawsuit against Berkshire during the fourth quarter of 2023 concerning the application of certain terms underlying theformula for calculating the purchase price to be paid upon exercise of the option. Subsequently, Berkshire filed a counterclaim
against Pilot Corporation. All litigation between Pilot Corporation and Berkshire was settled in January 2024, and we acquired
Pilot Corporation’s noncontrolling interest in PTC for $2.6 billion, increasing our interest in PTC to 100%.
A summary of the values of PTC’s assets acquired, liabilities assumed and redeemable noncontrolling interests as ofJanuary 31, 2023 are summarized as follows (in millions). Goodwill from this acquisition is expected to be deductible forincome tax purposes.

On September 1, 2023, a Berkshire Hathaway Energy (“BHE”) subsidiary acquired an additional 50% limited partnerinterest in Cove Point LNG, LP (“Cove Point”) for $3.3 billion, which increased our economic interest from 25% to 75%. Prior
to the transaction, we also owned 100% of the general partner interests. We previously treated Cove Point as a consolidated
subsidiary for financial reporting purposes because we concluded we have the power to direct the activities that mostsignificantly affect Cove Point, as well as the obligation to absorb losses and benefits that could be significant to Cove Point.
Accordingly, the interest acquired in the third quarter was an acquisition of a noncontrolling interest. We recorded a charge
based on Berkshire’s ownership percentage of BHE of $667 million to capital in excess of par for the excess of the consideration
paid over the carrying value of the noncontrolling interest acquired and deferred income tax assets arising from the transaction.

In 2019, we invested $10 billion in non-voting Cumulative Perpetual Preferred Stock of Occidental Petroleum
Corporation (“Occidental”) and in Occidental common stock warrants. During 2022, we began acquiring common stock ofOccidental. Our aggregate voting interest in Occidental common stock exceeded 20% on August 4, 2022, and we adopted theequity method as of that date. See Note 5. Our investments in the Occidental preferred stock and Occidental common stock
warrants are recorded at fair value and included as equity securities in our Consolidated Balance Sheets, as such investments
are not in-substance common stock under GAAP and are not eligible for the equity method.
The Occidental preferred stock accrues dividends at 8% per annum and is redeemable at the option of Occidental
commencing in 2029 at a redemption price equal to 105% of the liquidation value. As of December 31, 2023, our investment
in Occidental preferred stock had an aggregate liquidation value of approximately $8.5 billion. During 2023, Occidental issued
mandatory redemption notifications for approximately $1.5 billion of the aggregate liquidation value at a price of 110% of theliquidation value, plus accrued and unpaid dividends. The mandatory redemptions were due to excess distributions by
Occidental to its common stockholders, as defined under the terms of the Occidental preferred stock certificate of designations.
The Occidental common stock warrants allow us to purchase up to 83.86 million shares of Occidental common stock at
an exercise price of $59.62 per share. The warrants are exercisable in whole or in part until one year after the date the preferredstock is fully redeemed.
As of December 31, 2023, we owned 151.6 million shares of American Express Company (“American Express”)
common stock representing 21% of the outstanding common stock of American Express. Since 1995, we have been party toan agreement with American Express whereby we agreed to vote a significant portion of our shares in accordance with therecommendations of the American Express Board of Directors. We have also agreed to passivity commitments as requested by
the Board of Governors of the Federal Reserve System, which collectively, in our judgment, restrict our ability to exercise
significant influence over the operating and financial policies of American Express. Accordingly, we do not use the equity
method with respect to our investment in American Express common stock and we continue to record our investment at fairvalue.

Equity method investments

Berkshire and its subsidiaries hold investments in certain businesses that are accounted for pursuant to the equity method.
Currently, the most significant of these are our investments in the common stock of The Kraft Heinz Company (“Kraft Heinz”)
and Occidental. As of December 31, 2023, we owned 26.7% of the Kraft Heinz outstanding common stock and 27.8% of theoutstanding Occidental common stock, which excluded the potential effect of the exercise of the Occidental common stock
warrants.
Kraft Heinz manufactures and markets food and beverage products, including condiments and sauces, cheese and dairy,
meals, meats, refreshment beverages, coffee and other grocery products. Occidental is an international energy company, whose
activities include oil and natural gas exploration, development and production, and chemicals manufacturing businesses.
Occidental’s financial information is not available in time for concurrent reporting in our Consolidated Financial Statements.
Therefore, we report the equity method effects for Occidental on a one-quarter lag.
The common stock of Kraft Heinz and Occidental are publicly traded. The fair values and carrying values of these two
investments in addition to the carrying values of our other significant equity method investments are summarized as follows(in millions).

for other-than-temporary impairment as of December 31, 2023, and based on the prevailing facts and circumstances, concluded
the recognition of impairment charges in earnings were not required.
Our other significant equity method investments included our 50% interest in Berkadia Commercial Mortgage LLC(“Berkadia”), in which Jefferies Financial Group (“Jefferies”) owns the other 50% interest, and PTC through January 31, 2023.
Berkadia engages in mortgage banking, investment sales and servicing of commercial/multi-family real estate loans. Berkadia’scommercial paper borrowing capacity (currently limited to $1.5 billion) is supported by a surety policy issued by a Berkshire
insurance subsidiary. Jefferies is obligated to indemnify us for one-half of any losses incurred under the policy.
Beginning February 1, 2023, we ceased accounting for PTC under the equity method and began consolidating PTC for
financial reporting purposes. Our investment in PTC under the equity method was $3.2 billion at December 31, 2022. Equity
method earnings attributable to PTC were $105 million in 2023, $812 million in 2022 and $474 million in 2021.
As of December 31, 2023, the carrying values of our investments in Kraft Heinz and Berkadia approximated our shareof shareowners’ equity of each of these entities. The carrying value of our investment in Occidental common stock exceeded
our share of its shareholders’ equity as of September 30, 2023 by approximately $9.6 billion. Based upon the limited
information available to us, we concluded the excess represents goodwill.
Our earnings and distributions received from equity method investments are summarized in the following table (inmillions). The earnings we recorded in 2023 for Occidental included our share of its earnings for the fourth quarter of 2022
and first nine months of 2023. The earnings we recorded in 2022 for Occidental included our share of its earnings from August

equity securities we still own, as well as gains and losses on securities we sold during the year. As shown in the Consolidated
Statements of Cash Flows, our proceeds from sales of equity securities were approximately $40.6 billion in 2023, $33.7 billion
in 2022 and $15.8 billion in 2021. In the preceding table, investment gains and losses on equity securities sold during the year
represent the difference between the sales proceeds and the fair value of the equity securities sold at the beginning of theapplicable year or, if later, the purchase date. Our taxable gains and losses on equity securities sold are generally the difference
between the proceeds from sales and cost at the acquisition date. Equity securities sold produced taxable gains of $5.0 billion
in 2023, $769 million in 2022 and $3.6 billion in 2021. Other investment gains included approximately $3.0 billion in 2023
from the remeasurement of our pre-existing 38.6% interest in PTC through the application of acquisition accounting under
GAAP.

Notes to Consolidated Financial Statements(15) Dividend restrictions – Insurance subsidiaries
Payments of dividends by our insurance subsidiaries are restricted by insurance statutes and regulations. Without priorregulatory approval, our principal insurance subsidiaries may declare up to approximately $31 billion as ordinary dividends
during 2024. Investments in fixed maturity and equity securities and short-term investments on deposit with U.S. state insurance
authorities in accordance with state insurance regulations were approximately $5.2 billion at December 31, 2023 and $4.9
billion at December 31, 2022.
Combined shareholders’ equity of U.S.-based insurance subsidiaries determined pursuant to statutory accounting rules(Surplus as Regards Policyholders) was approximately $303 billion at December 31, 2023 and $272 billion at December 31,
2022. Statutory surplus differs from the corresponding amount based on GAAP due to differences in accounting for certain
assets and liabilities. For instance, deferred charges reinsurance assumed, the measurement of life, annuity and health insurance
benefits liabilities, deferred policy acquisition costs, unrealized gains on certain investments and related deferred income taxes
are recognized for GAAP but not for statutory reporting purposes. In addition, the carrying values of certain assets, such as
goodwill and non-insurance entities owned by our insurance subsidiaries, are not fully recognized for statutory reporting
purposes.

Our claim liabilities under property and casualty insurance and reinsurance contracts are based upon estimates of theultimate claim costs associated with claim occurrences as of the balance sheet date and include estimates for incurred-but-notreported (“IBNR”) claims. Incurred losses and loss adjustment expenses shown in the preceding table related to insured eventsoccurring in the current year (“current accident year”) and events occurring in all prior years (“prior accident years”). Incurredand paid losses and loss adjustment expenses are net of reinsurance recoveries. Current accident year incurred losses fromsignificant catastrophe events (losses in excess of $150 million per event) were approximately $925 million in 2023, $3.1
billion in 2022 ($2.5 billion from Hurricane Ian) and $2.9 billion in 2021 ($1.5 billion from Hurricane Ida). Current accident
year incurred losses for private passenger auto insurance declined in 2023 compared to 2022, reflecting lower claims
frequencies and higher average claims severities and increased significantly in 2022 versus 2021, attributable to increases inclaims frequencies and severities.

K-92

Notes to Consolidated Financial Statements(16) Unpaid losses and loss adjustment expenses
We recorded net reductions of estimated ultimate liabilities for prior accident years of $3.5 billion in 2023, $2.7 billion
in 2022 and $3.1 billion in 2021, which produced corresponding reductions in incurred losses and loss adjustment expenses inthose periods. These reductions, as percentages of the net liabilities at the beginning of each year, were 3.5% in 2023, 3.2% in
2022 and 4.0% in 2021.
We reduced estimated ultimate liabilities for prior accident years of primary insurance businesses by $2.1 billion in 2023,$1.1 billion in 2022 and $2.4 billion in 2021. The reductions in each year derived from private passenger auto, medical
professional liability, and property claims. Estimated ultimate liabilities for prior accident years of property and casualty
reinsurance businesses were reduced $1.4 billion in 2023, $1.6 billion in 2022 and $718 million in 2021. The reductions ineach year reflected reduced estimates from both property and casualty claims.
Estimated net claim liabilities for environmental and asbestos exposures, excluding liabilities under retroactive
reinsurance contracts, were approximately $2.0 billion at December 31, 2023 and $2.1 billion at December 31, 2022. Theseliabilities are subject to change due to changes in the legal and regulatory environment, among other factors. We are unable toreliably estimate additional losses or a range of losses that are reasonably possible to arise from these factors.
Disaggregated information concerning our claim liabilities is provided below and in the pages that follow. In this
discussion, “claim-tail” refers to the period between the claim occurrence date and claim settlement or payment date. A

GEICO
GEICO’s claim liabilities predominantly relate to various types of private passenger auto liability and physical damage
claims. For such claims, we establish and evaluate unpaid claim liabilities using standard actuarial loss development methods
and techniques. The actuarial methods utilize historical claims data, adjusted when deemed appropriate to reflect perceived
changes in loss patterns. Claim liabilities include average, case, case development and IBNR estimates.
We establish average liabilities based on expected severities for newly reported physical damage and liability claims
prior to establishing individual case reserves when insufficient time or information is available for specific claim estimates andfor large volumes of minor physical damage claims that are quickly settled. We establish case loss estimates for liability claims,
including estimates for loss adjustment expenses based on the facts and merits of the claim.
Claim estimates for liability coverages normally reflect greater uncertainty than for physical damage coverages, primarily
due to the longer claim-tails, the greater chance of litigation and the time needed to evaluate facts at the time the case estimate
is first established. Consequently, we establish additional case development liabilities, which are usually percentages of thecase liabilities. For unreported claims, IBNR claim liabilities are estimated by projecting the ultimate number of claims
expected (reported and unreported) for each significant coverage based on historical data, from which reported claims are
deducted to produce the estimated number of unreported claims. The product of the average cost per unreported claim and thenumber of unreported claims produces the IBNR liability estimate. We may record supplemental IBNR liabilities in certain
situations when actuarial techniques are difficult to apply.

Notes to Consolidated Financial Statements(16) Unpaid losses and loss adjustment expenses
GEICO’s net incurred and paid auto physical damage and liability losses and ALAE are summarized by accident year
below. IBNR and case development liabilities are as of December 31, 2023 and are net of estimated salvage and subrogation
recoveries. Claim counts are established when accidents that could result in a liability are reported and are based on policy
coverage. Each claim event may generate claims under multiple coverages and may result in multiple counts. The “Cumulative
Number of Reported Claims” includes the combined number of reported claims for all auto policy coverages. Dollars are in

liability and workers’ compensation and other casualty insurance, which includes commercial auto and general liability
insurance. Net incurred and paid losses and ALAE are summarized by accident year in the following tables, disaggregated by
medical professional liability coverages and workers’ compensation and other casualty coverages. IBNR and case development
liabilities are as of December 31, 2023. The cumulative number of reported claims reflects the number of individual claimants
and includes claims that ultimately resulted in no liability or payment. Dollars are in millions.
Medical Professional Liability
We estimate the ultimate expected incurred losses and loss adjustment expenses for medical professional claim liabilities
using a variety of commonly accepted actuarial methodologies, such as the paid and incurred development method andBornhuetter-Ferguson based methods, as well as other techniques that consider insured loss exposures and historical andexpected loss trends, among other factors. These methodologies produce loss estimates from which we determine our best
estimate. In addition, we study developments in older accident years and adjust initial loss estimates to reflect recent
developments based upon claim age, coverage and litigation experience.

Workers’ Compensation and Other Casualty
We periodically evaluate ultimate loss and loss adjustment expense estimates for workers’ compensation and othercasualty claims using a combination of commonly accepted actuarial methodologies such as the Bornhuetter-Ferguson andchain-ladder approaches using paid and incurred loss data. Paid and incurred loss data is segregated and analyzed by state dueto the different state regulatory frameworks that may impact certain factors, including the duration and amount of loss
payments. We also separately study the various components of liabilities, such as employee lost wages, medical expenses andthe costs of claims investigations and administration. We establish case liabilities for reported claims based upon the facts andcircumstances of the claim. The excess of the ultimate projected losses, including the expected development of case estimates,
and the case-basis liabilities is included in IBNR liabilities.

Notes to Consolidated Financial Statements(16) Unpaid losses and loss adjustment expenses
Our claim liabilities are principally a function of reported losses from ceding companies, case development and IBNR
liability estimates. Case loss estimates are reported either individually or in bulk as provided under the terms of the contracts.
We may independently evaluate case losses reported by the ceding company, and if deemed appropriate, establish additionalcase liabilities based on our estimates.
Estimated IBNR liabilities are affected by expected case loss emergence patterns and expected loss ratios, which areevaluated as groups of contracts with similar exposures or on a contract-by-contract basis. Estimated case and IBNR liabilities
for major catastrophe events are generally based on a per-contract assessment of the ultimate cost associated with the individualloss event. Claim count data is not provided consistently by ceding companies under our contracts or is otherwise consideredunreliable.
Net incurred and paid losses and ALAE of BHRG are disaggregated based on losses that are expected to have shorter
claim-tails (property) and losses expected to have longer claim-tails (casualty). Under certain contracts, the coverage can apply
to multiple lines of business written by the ceding company, whether property, casualty or combined, and the ceding company
may not report loss data by such lines consistently, if at all. In those instances, we allocated losses to property and casualty
coverages based on internal estimates. BHRG’s disaggregated incurred and paid losses and ALAE are summarized by accident
year. IBNR and case development liabilities are as of December 31, 2023. Dollars are in millions.

Notes to Consolidated Financial Statements(17) Retroactive reinsurance contracts
Retroactive reinsurance policies provide indemnification of losses and loss adjustment expenses of short-duration
insurance contracts with respect to underlying loss events that occurred prior to the contract inception date, which may include
significant levels of asbestos, environmental and other mass tort claims. Retroactive reinsurance contracts are generally subject
to aggregate policy limits and thus, our exposure to such claims under these contracts is likewise limited. Reconciliations of
the changes in estimated liabilities for retroactive reinsurance unpaid losses and loss adjustment expenses for each of the three
years ended December 31, 2023 follow (in millions).

In the preceding table, the classification of incurred losses and loss adjustment expenses is based on the inception datesof the contracts, which reflect when our exposure to losses began. We believe that analysis of losses incurred and paid byaccident year of the underlying event is irrelevant given that our exposure to losses incepts when the contract incepts and thatthe classification of reported claims and case development liabilities has little or no practical analytical value.
Incurred losses and loss adjustment expenses in the Consolidated Statements of Earnings include changes in estimatedliabilities and related deferred charge asset amortization and adjustments arising from the changes in estimated timing andamount of future loss payments. In 2023, we increased estimated ultimate liabilities under certain contracts by $1.1 billion,
which after adjustments to related deferred charge assets, produced an increase in incurred losses and loss adjustment expenses
of approximately $650 million. The increase derived from higher estimates for asbestos, environmental and other casualty
claims. Unamortized deferred charges on retroactive reinsurance contracts were $9.5 billion at December 31, 2023 and $9.9
billion at December 31, 2022.
In establishing retroactive reinsurance claim liabilities, we analyze historical aggregate loss payment patterns and project
losses into the future under various probability-weighted scenarios. We expect the claim-tail to be very long for many contracts,with some lasting several decades. We monitor claim payment activity and review ceding company reports and otherinformation concerning the underlying losses. We revise the expected timing and amounts of ultimate losses periodically or
when significant events are revealed.
We monitor evolving case law and its effect on asbestos, environmental and other mass tort claims. Changing laws orgovernment regulations, as well as newly identified toxins and injury events, newly reported claims, new theories of liability,
new contract interpretations and other factors could result in increases in these liabilities, which could be material to our resultsof operations. We are unable to reliably estimate the amount of additional net loss or the range of net loss that is reasonably
possible. Our estimates of ultimate liabilities for asbestos and environmental exposures under our contracts were approximately$12.2 billion at December 31, 2023 and $12.1 billion at December 31, 2022.

Notes to Consolidated Financial Statements(19) Notes payable and other borrowings
Berkshire parent company borrowings consist of senior unsecured debt. During 2023, Berkshire repaid approximately$4.3 billion of maturing senior notes and issued ¥286.4 billion par (approximately $2.05 billion) of senior notes with a weighted
average interest rate of 1.15% and maturity dates ranging from 2026 to 2058. Borrowings of BHFC, a wholly owned financesubsidiary of Berkshire, consist of senior unsecured notes used to fund manufactured housing loans originated or acquired andequipment held for lease of certain subsidiaries. BHFC borrowings are fully and unconditionally guaranteed by Berkshire.
Berkshire also guarantees certain debt of other subsidiaries, aggregating approximately $2.7 billion at December 31, 2023.
Generally, Berkshire’s guarantee of a subsidiary’s debt obligation is an absolute, unconditional and irrevocable guarantee forthe full and prompt payment when due of all payment obligations.
The carrying values of Berkshire and BHFC non-U.S. Dollar denominated senior notes (€6.85 billion, £1.75 billion and¥1,259 billion par at December 31, 2023) reflect the applicable exchange rates as of each balance sheet date. The effects ofchanges in foreign currency exchange rates during the period on our borrowings are recorded in earnings as a component ofselling, general and administrative expenses. Changes in the exchange rates produced pre-tax gains of $217 million in 2023,$1.7 billion in 2022 and $1.3 billion in 2021.
Notes payable and other borrowings of our railroad, utilities and energy businesses are summarized below (dollars arein millions). The weighted average interest rates and maturity date ranges are based on borrowings as of December 31, 2023.

BHE subsidiary debt represents amounts issued pursuant to separate financing agreements. Substantially all of the assetsof certain BHE subsidiaries are, or may be, pledged or encumbered to support or otherwise secure such debt. These borrowing
arrangements generally contain various covenants, including covenants which pertain to leverage ratios, interest coverage ratios
and/or debt service coverage ratios. In 2023, BHE subsidiaries issued $4.2 billion par of term debt with a weighted averageinterest rate of 5.7% and maturity dates ranging from 2033 to 2055, and BHE and its subsidiaries repaid approximately $3.7
billion of term debt. In 2024, BHE subsidiaries issued $5.1 billion of term debt with a weighted average interest rate of 5.4%
and maturity dates ranging from 2029 to 2055 and repaid short term borrowings of approximately $2.8 billion.
PTC’s borrowings primarily represent secured syndicated loans. BNSF’s borrowings are primarily senior unsecured
debentures. During 2023, BNSF issued $1.6 billion par of 5.2% debentures due in 2054 and repaid approximately $1.6 billionof term debt. As of December 31, 2023, BHE, BNSF and PTC and their subsidiaries were in compliance with all applicabledebt covenants. Berkshire does not guarantee any debt, borrowings or lines of credit of BHE, BNSF, PTC or their subsidiaries.
Unused lines of credit and commercial paper capacity to support operations and provide additional liquidity for our
subsidiaries were approximately $9.4 billion at December 31, 2023, of which approximately $6.0 billion related to BHE andits subsidiaries.
Debt principal repayments expected during each of the next five years are as follows (in millions). Amounts in 2024

We have not established deferred income taxes on accumulated undistributed earnings of certain foreign subsidiaries,
which are expected to be reinvested indefinitely. Repatriation of all accumulated earnings of foreign subsidiaries would be
impracticable to the extent that such earnings represent capital to support ongoing business operations. Generally, no U.S.
federal income taxes will be imposed on future distributions of foreign earnings under current law. However, distributions to
the U.S. or other foreign jurisdictions could be subject to withholding and other local taxes.

credits arising from affordable housing investments.
We file income tax returns in the U.S. and in state, local and foreign jurisdictions. We have settled income tax liabilities
with the U.S. federal taxing authority (“IRS”) for tax years through 2011. The 2012 and 2013 tax years are under review by the
IRS’s Independent Office of Appeals, and the IRS is currently auditing tax years 2014 through 2019. We are also under audit
or subject to audit with respect to income taxes in state and foreign jurisdictions. It is reasonably possible that certain of theseincome tax examinations will be settled in 2024. We currently do not believe that the outcome of unresolved issues or claims
will be material to our Consolidated Financial Statements.
At December 31, 2023 and 2022, net unrecognized tax benefits were $480 million and $440 million, respectively.
Included in the balance at December 31, 2023, were $420 million of tax positions that, if recognized, would impact the effective
tax rate. We do not expect material increases to the estimated amount of unrecognized tax benefits during 2024.
On August 16, 2022, the Inflation Reduction Act of 2022 (“the 2022 Act”) was signed into law. The 2022 Act contains
numerous provisions, including a 15% corporate alternative minimum income tax (“CAMT”) on “adjusted financial statement
income”, expanded tax credits for clean energy incentives and a 1% excise tax on corporate stock repurchases. The provisionsof the 2022 Act are effective for tax years beginning after December 31, 2022. The extent to which the Company incurs CAMT
will depend on the facts and circumstances of the given tax year. We do not expect to incur a CAMT liability in 2023. The
Internal Revenue Service and the U.S. Department of Treasury may release additional guidance in the future. We will continue
to evaluate the impact of the 2022 Act as more guidance becomes available.
The Organization for Economic Co-operation and Development has issued Pillar Two model rules introducing a new
global minimum tax of 15% intended to be effective on January 1, 2024. While the U.S. has not yet adopted the Pillar Two
rules, various other governments around the world are enacting legislation. As currently designed, Pillar Two will ultimately
apply to our worldwide operations. Considering we do not have material operations in jurisdictions with tax rates lower than
the Pillar Two minimum, these rules are not expected to materially increase our global tax costs. There remains uncertainty as
to the final Pillar Two model rules. We will continue to monitor U.S. and global legislative action related to Pillar Two forpotential impacts.

Notes to Consolidated Financial Statements(21) Fair value measurements
The fair values of substantially all of our financial instruments were measured using market or income approaches. The
hierarchy for measuring fair value consists of Levels 1 through 3, which are described below.
Level 1 – Inputs represent unadjusted quoted prices for identical assets or liabilities exchanged in active markets.
Level 2 – Inputs include directly or indirectly observable inputs (other than Level 1 inputs) such as quoted prices
for similar assets or liabilities exchanged in active or inactive markets; quoted prices for identical assets or liabilities
exchanged in inactive markets; other inputs that may be considered in fair value determinations of the assets or liabilities,
such as interest rates and yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates; andinputs that are derived principally from or corroborated by observable market data by correlation or other means. Pricing
evaluations generally reflect discounted expected future cash flows, which incorporate yield curves for instruments withsimilar characteristics, such as credit ratings, estimated durations and yields for other instruments of the issuer or entities
in the same industry sector.
Level 3 – Inputs include unobservable inputs used in the measurement of assets and liabilities. Management isrequired to use its own assumptions regarding unobservable inputs because there is little, if any, market activity in theassets or liabilities and it may be unable to corroborate the related observable inputs. Unobservable inputs require
management to make certain projections and assumptions about the information that would be used by market
participants in valuing assets or liabilities.
Reconciliations of significant assets and liabilities measured and carried at fair value on a recurring basis with the use ofsignificant unobservable inputs (Level 3) for each of the three years ending December 31, 2023 follow (in millions).

Notes to Consolidated Financial Statements(21) Fair value measurements
Investments in equity securities in the preceding table include our investments in certain preferred and common stock
warrants that do not have readily determinable market values as defined under GAAP. These investments are private placementswith contractual terms that restrict transfers and currently prevent us from economically hedging our investments. We applied
discounted cash flow techniques in valuing the preferred stock and we made assumptions regarding the expected duration of
the investment and the effects of subordination in liquidation. In valuing the common stock warrants, we used a warrant
valuation model. While most of the inputs to the warrant model are observable, we made assumptions regarding the expected
duration and volatility.

Each Class A common share is entitled to one vote per share. Class B common stock possesses dividend and distribution
rights equal to one-fifteen-hundredth (1/1,500) of such rights of Class A common stock. Each Class B common share possesses
voting rights equal to one-ten-thousandth (1/10,000) of the voting rights of a Class A share. Unless otherwise required under
Delaware General Corporation Law, Class A and Class B common shares vote as a single class. Each share of Class A common
stock is convertible, at the option of the holder, into 1,500 shares of Class B common stock. Class B common stock is notconvertible into Class A common stock. On an equivalent Class A common stock basis, there were 1,441,483 shares outstanding
as of December 31, 2023 and 1,459,733 shares outstanding as of December 31, 2022.
Since we have two classes of common stock, we provide earnings per share data on the Consolidated Statements ofEarnings for average equivalent Class A shares outstanding and average equivalent Class B shares outstanding. Class B sharesare economically equivalent to one-fifteen-hundredth (1/1,500) of a Class A share. Average equivalent Class A shares
outstanding represents average Class A shares outstanding plus one-fifteen-hundredth (1/1,500) of the average Class B shares
outstanding. Average equivalent Class B shares outstanding represents average Class B shares outstanding plus 1,500 times
average Class A shares outstanding.
Berkshire’s common stock repurchase program, as amended, permits Berkshire to repurchase shares any time that
Warren Buffett, Berkshire’s Chairman of the Board and Chief Executive Officer, believes that the repurchase price is below
Berkshire’s intrinsic value, conservatively determined. The program continues to allow share repurchases in the open market
or through privately negotiated transactions and does not specify a maximum number of shares to be repurchased. However,repurchases will not be made if they would reduce the total value of Berkshire’s consolidated cash, cash equivalents and U.S.
Treasury Bill holdings below $30 billion. The repurchase program does not obligate Berkshire to repurchase any specific dollar
amount or number of Class A or Class B shares and there is no expiration date to the program.

The projected benefit obligation (“PBO”) is the actuarial present value of benefits earned based upon service andcompensation prior to the valuation date and, if applicable, includes assumptions regarding future compensation levels. Benefit
obligations under qualified U.S. defined benefit pension plans are funded through assets held in trusts. Pension obligations
under certain other plans are unfunded and the aggregate PBOs of such plans were $1.0 billion and $1.1 billion as of December
31, 2023 and 2022, respectively. The costs of certain BHE pension plans are expected to be recoverable through the regulated
rate making process.
The funded status reflected in the Consolidated Balance Sheets at year end 2023 and 2022 and reconciliations of thechanges in PBOs and plan assets related to BHE’s pension plans and all other pension plans for each of the two years ending

See Note 21 for a discussion of fair value measurements. Plan assets are generally invested with the long-term objectiveof producing earnings to adequately cover expected benefit obligations, while assuming a prudent level of risk. Allocations
may change due to changing market conditions and investment opportunities. The expected rates of return on plan assets reflectsubjective assessments of expected long-term investment returns. Generally, past investment returns are not given significant
consideration when establishing assumptions for expected long-term rates of return on plan assets. Actual experience will differ
from the assumed rates of return.

Notes to Consolidated Financial Statements(26) Business segment data
Our operating businesses include a large and diverse group of insurance, manufacturing, service and retailing businesses.
We organize our reportable business segments in a manner that reflects how management views those business activities.
Certain businesses are grouped together for segment reporting based upon similar products or product lines, marketing, sellingand distribution characteristics, even though those business units are operated under separate local management. We acquired
control of PTC on January 31, 2023 and PTC is considered a reportable segment beginning February 1, 2023. In thispresentation, statement of earnings and capital expenditures data of the PTC segment are for the eleven months ending
December 31, 2023. Previously, our earnings from PTC were determined under the equity method and included in earnings
from non-controlled businesses.
The tabular information that follows shows data of reportable segments reconciled to amounts reflected in our
Consolidated Financial Statements. Intersegment transactions are not eliminated from segment results when management
considers those transactions in assessing the results of the respective segments. Furthermore, our management does not consider
investment and derivative gains/losses, impairments or amortization of certain business acquisition accounting adjustments orcertain other corporate income and expense items in assessing the financial performance of operating units. Collectively, these
items are included in reconciliations of segment amounts to consolidated amounts.
Berkshire’s operating segments are as follows.

Notes to Consolidated Financial Statements(26) Business segment data
Consolidated sales, service and leasing revenues were $164.1 billion in 2023, $165.0 billion in 2022 and $151.0 billion
in 2021. Sales, service and leasing revenues attributable to the United States were 85% in 2023, 86% in 2022 and 85% in 2021
of such amounts. The remainder of sales, service and leasing revenues were primarily in Europe, the Asia-Pacific region andCanada. Railroad, utilities and energy revenues were $101.4 billion in 2023, $52.1 billion in 2022 and $48.2 billion in 2021.
Railroad, utilities and energy revenues attributable to the United States were 94% in 2023 and 96% in both 2022 and 2021. At
December 31, 2023, approximately 90% of our consolidated net property, plant and equipment and equipment held for lease
was located in the United States with the remainder primarily in the United Kingdom and Canada.
(27) Contingencies and commitments
We are parties in a variety of legal actions that routinely arise out of the normal course of business, including legal actions
seeking to establish liability directly through insurance contracts or indirectly through reinsurance contracts issued by Berkshire
subsidiaries. Plaintiffs occasionally seek punitive or exemplary damages. We do not believe that such normal and routine
litigation will have a material effect on our financial condition or results of operations.
PacifiCorp, a wholly owned subsidiary of Berkshire’s 92% owned subsidiary, Berkshire Hathaway Energy Company(“BHE”), operates as a regulated electric utility in Oregon and other Western states. In September 2020, a severe weather event
resulting in high winds, low humidity and warm temperatures, contributed to several major wildfires (the “2020 Wildfires”),
which resulted in real and personal property and natural resource damage, personal injuries and loss of life and widespread
power outages in Oregon and Northern California. The wildfires spread across certain parts of PacifiCorp’s service territoryand surrounding areas across multiple counties in Oregon and California, including Siskiyou County, California; Jackson
County, Oregon; Douglas County, Oregon; Marion County, Oregon; Lincoln County, Oregon; and Klamath County, Oregon,burning over 500,000 acres in aggregate. Third-party reports for these wildfires indicate over 2,000 structures destroyed,
including residences; several structures damaged; multiple individuals injured; and several fatalities.
On July 29, 2022, the 2022 McKinney Fire began in the Oak Knoll Ranger District of the Klamath National Forest in
Siskiyou County, California located in PacifiCorp’s service territory (the “2022 Wildfire”). Third-party reports indicate thatthe 2022 Wildfire resulted in 11 structures damaged, 185 structures destroyed, 12 injuries and four fatalities and consumed
60,000 acres in aggregate. The 2020 Wildfires and 2022 Wildfire, together, are referred to as the “Wildfires”.
Investigations into the cause and origin of each of the Wildfires are complex and ongoing and have been or are being
conducted by various entities, including the U.S. Forest Service, the California Public Utilities Commission, the Oregon
Department of Forestry, the Oregon Department of Justice, PacifiCorp and various experts engaged by PacifiCorp.
As of the date of this filing, a significant number of complaints and demands alleging similar claims related to the 2020
Wildfires have been filed in Oregon and California, including a class action complaint in Oregon for which two jury verdicts
were issued in June 2023 and January 2024 as described below. The plaintiffs seek damages for economic losses, noneconomic
losses, including mental suffering, emotional distress, personal injury and loss of life, punitive damages, other damages andattorneys’ fees. Several insurance carriers have filed subrogation complaints in Oregon and California with allegations similar
to those made in the aforementioned complaints. Additionally, the U.S. and Oregon Departments of Justice have informed
PacifiCorp that they are contemplating filing actions against PacifiCorp in connection with certain of the Oregon 2020
Wildfires. PacifiCorp is actively cooperating with the U.S. and Oregon Departments of Justice on resolving these alleged
claims, including through the pursuit of alternative dispute resolution.
Numerous lawsuits on behalf of plaintiffs related to the 2020 Wildfires have been filed in Oregon and California,
including a class action complaint against PacifiCorp that was filed in 2020, captioned Jeanyne James et al. v. PacifiCorp etal., in Multnomah County Circuit Court, Oregon (the “James case”). The plaintiffs seek damages for economic losses, noneconomic losses, including mental suffering, emotional distress, personal injury and loss of life, punitive damages, otherdamages and attorneys’ fees.
Amounts sought in the complaints and demands filed in Oregon and in certain demands in California approximate $8
billion, excluding any doubling or trebling of damages included in the complaints. Generally, the complaints filed in California
do not specify damages sought and are not included in this amount. Final determinations of liability will only be made following
the completion of comprehensive investigations, litigation and similar processes. Multiple lawsuits have also been filed in
California on behalf of plaintiffs related to the 2022 Wildfire. The plaintiffs seek damages for economic losses, non-economic
losses, including mental suffering, emotional distress, personal injury and loss of life, punitive damages, other damages andattorneys’ fees, but the amount of damages sought is not specified.

Notes to Consolidated Financial Statements(27) Contingencies and commitments
In June 2023, a jury issued its verdict for the 17 named plaintiffs in the James case finding PacifiCorp liable to the 17
individual plaintiffs and to the class with respect to the four 2020 Wildfires named in the complaint. The jury awarded the 17
named plaintiffs $90 million of damages, including $4 million of economic and property damages, $68 million of non-economic
damages and $18 million of punitive damages based on a 0.25 multiplier of the economic and non-economic damages.
In September 2023, the Multnomah County Circuit Court ordered trial dates for two consolidated jury trials including
approximately 10 class members each and a third trial for certain commercial timber plaintiffs wherein plaintiffs in each of thethree damages phase trials will present evidence regarding their damages. The first of these trials addressing nine individual
plaintiffs was held in January 2024 while the remaining trials are scheduled at various dates through April 2024.
In January 2024, the Multnomah County Circuit Court entered a limited judgment and money award for the June 2023
James case verdict. The limited judgment awards the aforementioned damages, as well as doubling of the economic damages
and offsetting of any insurance proceeds received by plaintiffs. The limited judgment created a lien against PacifiCorp,
attaching a debt for the money awards. PacifiCorp posted a supersedeas bond, which stays any effort to seek payment of thejudgment pending final resolution of any appeals. Under ORS 82.010, interest at a rate of 9% per annum will accrue on the
judgment commencing at the date the judgment was entered until the entire money award is paid, amended or reversed by anappellate court.
In January 2024, the jury for the first James damages phase trial awarded nine plaintiffs $62 million of damages,
including $6 million of economic damages and $56 million of noneconomic damages. After the January 2024 jury verdict, theMultnomah County Circuit Court doubled the economic damages to $12 million and added $16 million of punitive damages
using the 0.25 multiplier determined by the jury for the June 2023 James case verdict. PacifiCorp will request that theMultnomah County Circuit Court judge offset the damage awards by deducting insurance proceeds received by any of the nine
plaintiffs.
PacifiCorp has filed its notice of appeal of the jury’s findings and damage awards associated with the June 2023 verdictin the James case, including whether the case can proceed as a class action, and filed a motion to stay further damages phasetrials. On February 14, 2024, the Oregon Court of Appeals denied PacifiCorp’s request to stay the damages phase trials.
PacifiCorp intends to appeal the jury’s damage awards associated with the January 2024 jury verdict once the judgment isentered. On February 13, 2024, the 17 named plaintiffs filed a notice of cross-appeal as to the January 2024 limited judgment
and money award. The appeals process and further actions could take several years.
A provision for a loss contingency is recorded when it is probable a liability has been incurred and the amount of loss
can be reasonably estimated. PacifiCorp evaluates the related range of reasonably estimated losses and records a loss based on
its best estimate within that range or the lower end of the range if there is no better estimate.
Estimated probable losses associated with the Wildfires were based on the information available to the date of this filing,including (i) ongoing cause and origin investigations; (ii) ongoing settlement and mediation discussions; (iii) other litigation
matters and upcoming legal proceedings; and (iv) the status of the James case. Wildfire estimated losses include estimates forfire suppression costs, real and personal property damages, natural resource damages for certain areas and non-economic
damages such as personal injury damages and loss of life damages that are considered probable of being incurred and that it isable to reasonably estimate at this time and which is subject to change as additional relevant information becomes available.
PacifiCorp recorded estimated pre-tax probable Wildfire losses, before expected related insurance recoveries, ofapproximately $1.9 billion in 2023 and $225 million in 2022. Such amounts, net of expected insurance recoveries, wereapproximately $1.7 billion in 2023 and $64 million in 2022, which were included in energy operating expenses in theaccompanying Consolidated Statements of Earnings. PacifiCorp paid $631 million in settlements in 2023 and $53 million in
2022 associated with the 2020 Wildfires. PacifiCorp’s cumulative charges to date for estimated probable Wildfire losses
through December 31, 2023, before expected insurance recoveries, were $2.4 billion.
It is reasonably possible PacifiCorp will incur significant additional Wildfire losses beyond the amounts currently
accrued; however, it is currently unable to reasonably estimate the range of possible additional losses that could be incurred
due to the number of properties and parties involved, including claimants in the class to the James case, the variation in those
types of properties and lack of available details and the ultimate outcome of legal actions.

K-116

Notes to Consolidated Financial Statements(27) Contingencies and commitments
HomeServices of America, Inc. (“HomeServices”), a wholly owned subsidiary of BHE, is currently defending against
eleven antitrust cases, all in federal district courts. In each case, plaintiffs claim HomeServices and certain of its subsidiaries
conspired with co-defendants to artificially inflate real estate commissions by following and enforcing multiple listing service(“MLS”) rules that require listing agents to offer a commission split to cooperating agents in order for the property to appear
on the MLS (“Cooperative Compensation Rule”). None of the complaints specify damages sought. However, two cases also
allege Texas state law deceptive trade practices claims, for which plaintiffs have provided written notice of the damages sought
totaling approximately $9 billion by separate notice as required by Texas law.
In one of these cases, Burnett (formerly Sitzer) et al. v. HomeServices of America, Inc. et al., a jury trial commenced on
October 16, 2023, and the jury returned a verdict for the plaintiffs on October 31, 2023, finding that the named defendants
participated in a conspiracy to follow and enforce the Cooperative Compensation Rule, which had the purpose or effect ofraising, inflating, or stabilizing broker commission rates paid by home sellers. The jury further found that the class plaintiffs
had proved damages in the amount of $1.8 billion. Federal law authorizes trebling of damages and the award of pre-judgmentinterest and attorney fees. Joint and several liability applies for the co-defendants. HomeServices intends to vigorously appeal
on multiple grounds the jury’s findings and damage award. The appeals process and further actions could take several years.
Based on available information to date, HomeServices believes losses are likely to occur as a result of the jury verdict in
the Burnett case and that such damages could be up to $5.4 billion, excluding attorneys’ fees, prejudgment interest and othercosts subject to determination by the court. However, HomeServices is currently unable to reasonably estimate such loss due
to, among other reasons, the joint and several nature of the liability and the early stages of the appeals process.
It is also reasonably possible that HomeServices will incur losses from the ten other antitrust cases. However,
HomeServices is unable to reasonably estimate a specific range of possible losses that could be incurred due to, among otherreasons, lack of information about the size of the plaintiff class and potential damages, as well as the joint and several natureof potential liability of the defendants.
Berkshire and certain of its subsidiaries are also involved in other kinds of legal actions, some of which assert or may
assert claims or seek to impose fines and penalties. We currently believe that liabilities that may arise as a result of such otherpending legal actions will not have a material effect on our consolidated financial condition or results of operations.
Our subsidiaries regularly make commitments in the ordinary course of business to purchase goods and services in the
future for use in their businesses, which are not yet reflected in our Consolidated Financial Statements. The most significant of
our long-term commitments relate to our railroad, utilities and energy businesses, our shared aircraft ownership and leasing
business and certain materials purchase commitments. As of December 31, 2023, estimated future payments under thosearrangements over the next five years were as follows: $10 billion in 2024, $4 billion in 2025, $3 billion in 2026, $3 billion in
2027 and $2 billion in 2028.
We may be obligated to acquire certain noncontrolling interests in less-than-wholly-owned subsidiaries in the future,
pursuant to the terms of agreements with the noncontrolling shareholders for cash or other assets. The timing and the amountof any future payments that might be required to such noncontrolling shareholders are contingent on future actions of thenoncontrolling owners and the value of the interest being acquired.
