Berkshire’s Performance vs. the S&P 500

BERKSHIRE HATHAWAY INC.

To the Shareholders of Berkshire Hathaway Inc.:

Charlie Munger, my long-time partner, and I have the job of managing a portion of your savings. We are honored by your trust.

Our position carries with it the responsibility to report to you what we would like to know if we were the absentee owner and you were the manager. We enjoy communicating directly with you through this annual letter, and through the annual meeting as well.

Our policy is to treat all shareholders equally. Therefore, we do not hold discussions with analysts nor large institutions. Whenever possible, also, we release important communications on Saturday mornings in order to maximize the time for shareholders and the media to absorb the news before markets open on Monday.

A wealth of Berkshire facts and figures are set forth in the annual 10-K that the company regularly files with the S.E.C. and that we reproduce on pages K-1 – K-119. Some shareholders will find this detail engrossing; others will simply prefer to learn what Charlie and I believe is new or interesting at Berkshire.

Alas, there was little action of that sort in 2021. We did, though, make reasonable progress in increasing the intrinsic value of your shares. That task has been my primary duty for 57 years. And it will continue to be.

What You Own

Berkshire owns a wide variety of businesses, some in their entirety, some only in part. The second group largely consists of marketable common stocks of major American companies. Additionally, we own a few non-U.S. equities and participate in several joint ventures or other collaborative activities.

Whatever our form of ownership, our goal is to have meaningful investments in businesses with both durable economic advantages and a first-class CEO. Please note particularly that we own stocks based upon our expectations about their long-term business performance and not because we view them as vehicles for timely market moves. That point is crucial: Charlie and I are not stock-pickers; we are business-pickers.

I make many mistakes. Consequently, our extensive collection of businesses includes some enterprises that have truly extraordinary economics, many others that enjoy good economic characteristics, and a few that are marginal. One advantage of our common-stock segment is that – on occasion – it becomes easy to buy pieces of wonderful businesses at wonderful prices. That shooting-fish-in-a-barrel experience is very rare in negotiated transactions and never occurs en masse. It is also far easier to exit from a mistake when it has been made in the marketable arena.

Surprise, Surprise

Here are a few items about your company that often surprise even seasoned investors:

• Many people perceive Berkshire as a large and somewhat strange collection of financial assets. In truth, Berkshire owns and operates more U.S.-based “infrastructure” assets – classified on our balance sheet as property, plant and equipment – than are owned and operated by any other American corporation. That supremacy has never been our goal. It has, however, become a fact.

At yearend, those domestic infrastructure assets were carried on Berkshire’s balance sheet at $158 billion. That number increased last year and will continue to increase. Berkshire always will be building.

• Every year, your company makes substantial federal income tax payments. In 2021, for example, we paid $3.3 billion while the U.S. Treasury reported total corporate income-tax receipts of $402 billion. Additionally, Berkshire pays substantial state and foreign taxes. “I gave at the office” is an unassailable assertion when made by Berkshire shareholders.

Berkshire’s history vividly illustrates the invisible and often unrecognized financial partnership between government and American businesses. Our tale begins early in 1955, when Berkshire Fine Spinning and Hathaway Manufacturing agreed to merge their businesses. In their requests for shareholder approval, these venerable New England textile companies expressed high hopes for the combination.

The Hathaway solicitation, for example, assured its shareholders that “The combination of the resources and managements will result in one of the strongest and most efficient organizations in the textile industry.” That upbeat view was endorsed by the company’s advisor, Lehman Brothers (yes, that Lehman Brothers).

I’m sure it was a joyous day in both Fall River (Berkshire) and New Bedford (Hathaway) when the union was consummated. After the bands stopped playing and the bankers went home, however, the shareholders reaped a disaster.

In the nine years following the merger, Berkshire’s owners watched the company’s net worth crater from $51.4 million to $22.1 million. In part, this decline was caused by stock repurchases, ill-advised dividends and plant shutdowns. But nine years of effort by many thousands of employees delivered an operating loss as well. Berkshire’s struggles were not unusual: The New England textile industry had silently entered an extended and non-reversible death march.

During the nine post-merger years, the U.S. Treasury suffered as well from Berkshire’s troubles. All told, the company paid the government only $337,359 in income tax during that period – a pathetic $100 per day.

Early in 1965, things changed. Berkshire installed new management that redeployed available cash and steered essentially all earnings into a variety of good businesses, most of which remained good through the years. Coupling reinvestment of earnings with the power of compounding worked its magic, and shareholders prospered.

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

In fairness to our governmental partner, our shareholders should acknowledge – indeed trumpet – the fact that Berkshire’s prosperity has been fostered mightily because the company has operated in America. Our country would have done splendidly in the years since 1965 without Berkshire. Absent our American home, however, Berkshire would never have come close to becoming what it is today. When you see the flag, say thanks.

• From an $8.6 million purchase of National Indemnity in 1967, Berkshire has become the world leader in insurance “float” – money we hold and can invest but that does not belong to us. Including a relatively small sum derived from life insurance, Berkshire’s total float has grown from $19 million when we entered the insurance business to $147 billion.

So far, this float has cost us less than nothing. Though we have experienced a number of years when insurance losses combined with operating expenses exceeded premiums, overall we have earned a modest 55-year profit from the underwriting activities that generated our float.

Of equal importance, float is very sticky. Funds attributable to our insurance operations come and go daily, but their aggregate total is immune from precipitous decline. When it comes to investing float, we can therefore think long-term.

If you are not already familiar with the concept of float, I refer you to a long explanation on page A-5. To my surprise, our float increased $9 billion last year, a buildup of value that is important to Berkshire owners though is not reflected in our GAAP (“generally-accepted accounting principles”) presentation of earnings and net worth.

Much of our huge value creation in insurance is attributable to Berkshire’s good luck in my 1986 hiring of Ajit Jain. We first met on a Saturday morning, and I quickly asked Ajit what his insurance experience had been. He replied, “None.”

I said, “Nobody’s perfect,” and hired him. That was my lucky day: Ajit actually was as perfect a choice as could have been made. Better yet, he continues to be – 35 years later.

One final thought about insurance: I believe that it is likely – but far from assured – that Berkshire’s float can be maintained without our incurring a long-term underwriting loss. I am certain, however, that there will be some years when we experience such losses, perhaps involving very large sums.

Berkshire is constructed to handle catastrophic events as no other insurer – and that priority will remain long after Charlie and I are gone.

Our Four Giants

Through Berkshire, our shareholders own many dozens of businesses. Some of these, in turn, have a collection of subsidiaries of their own. For example, Marmon has more than 100 individual business operations, ranging from the leasing of railroad cars to the manufacture of medical devices.

• Nevertheless, operations of our “Big Four” companies account for a very large chunk of Berkshire’s value. Leading this list is our cluster of insurers. Berkshire effectively owns 100% of this group, whose massive float value we earlier described. The invested assets of these insurers are further enlarged by the extraordinary amount of capital we invest to back up their promises.

5

The insurance business is made to order for Berkshire. The product will never be obsolete, and sales volume will generally increase along with both economic growth and inflation. Also, integrity and capital will forever be important. Our company can and will behave well.

There are, of course, other insurers with excellent business models and prospects. Replication of Berkshire’s operation, however, would be almost impossible.

• Apple – our runner-up Giant as measured by its yearend market value – is a different sort of holding. Here, our ownership is a mere 5.55%, up from 5.39% a year earlier. That increase sounds like small potatoes. But consider that each 0.1% of Apple’s 2021 earnings amounted to $100 million. We spent no Berkshire funds to gain our accretion. Apple’s repurchases did the job.

It’s important to understand that only dividends from Apple are counted in the GAAP earnings Berkshire reports – and last year, Apple paid us $785 million of those. Yet our “share” of Apple’s earnings amounted to a staggering $5.6 billion. Much of what the company retained was used to repurchase Apple shares, an act we applaud. Tim Cook, Apple’s brilliant CEO, quite properly regards users of Apple products as his first love, but all of his other constituencies benefit from Tim’s managerial touch as well.

• BNSF, our third Giant, continues to be the number one artery of American commerce, which makes it an indispensable asset for America as well as for Berkshire. If the many essential products BNSF carries were instead hauled by truck, America’s carbon emissions would soar.

Your railroad had record earnings of $6 billion in 2021. Here, it should be noted, we are talking about the old-fashioned sort of earnings that we favor: a figure calculated after interest, taxes, depreciation, amortization and all forms of compensation. (Our definition suggests a warning: Deceptive “adjustments” to earnings – to use a polite description – have become both more frequent and more fanciful as stocks have risen. Speaking less politely, I would say that bull markets breed bloviated bull . . ..)

BNSF trains traveled 143 million miles last year and carried 535 million tons of cargo. Both accomplishments far exceed those of any other American carrier. You can be proud of your railroad.

• BHE, our final Giant, earned a record $4 billion in 2021. That’s up more than 30-fold from the $122 million earned in 2000, the year that Berkshire first purchased a BHE stake. Now, Berkshire owns 91.1% of the company.

BHE’s record of societal accomplishment is as remarkable as its financial performance. The company had no wind or solar generation in 2000. It was then regarded simply as a relatively new and minor participant in the huge electric utility industry. Subsequently, under David Sokol’s and Greg Abel’s leadership, BHE has become a utility powerhouse (no groaning, please) and a leading force in wind, solar and transmission throughout much of the United States.

Greg’s report on these accomplishments appears on pages A-3 and A-4. The profile you will find there is not in any way one of those currently-fashionable “green-washing” stories. BHE has been faithfully detailing its plans and performance in renewables and transmissions every year since 2007.

To further review this information, visit BHE’s website at brkenergy.com. There, you will see that the company has long been making climate-conscious moves that soak up all of its earnings. More opportunities lie ahead. BHE has the management, the experience, the capital and the appetite for the huge power projects that our country needs.

Investments

• This is our actual purchase price and also our tax basis.

** Held by BHE; consequently, Berkshire shareholders have only a 91.1% interest in this position. *** Includes a $10 billion investment in Occidental Petroleum, consisting of preferred stock and warrants to buy common stock, a combination now being valued at $10.7 billion.

In addition to the footnoted Occidental holding and our various common-stock positions, Berkshire also owns a 26.6% interest in Kraft Heinz (accounted for on the “equity” method, not market value, and carried at $13.1 billion) and 38.6% of Pilot Corp., a leader in travel centers that had revenues last year of $45 billion.

Since we purchased our Pilot stake in 2017, this holding has warranted “equity” accounting treatment. Early in 2023, Berkshire will purchase an additional interest in Pilot that will raise our ownership to 80% and lead to our fully consolidating Pilot’s earnings, assets and liabilities in our financial statements.

U.S. Treasury Bills

Berkshire’s balance sheet includes $144 billion of cash and cash equivalents (excluding the holdings of BNSF and BHE). Of this sum, $120 billion is held in U.S. Treasury bills, all maturing in less than a year. That stake leaves Berkshire financing about 1⁄ 2 of 1% of the publicly-held national debt.

Charlie and I have pledged that Berkshire (along with our subsidiaries other than BNSF and BHE) will always hold more than $30 billion of cash and equivalents. We want your company to be financially impregnable and never dependent on the kindness of strangers (or even that of friends). Both of us like to sleep soundly, and we want our creditors, insurance claimants and you to do so as well.

But $144 billion?

That imposing sum, I assure you, is not some deranged expression of patriotism. Nor have Charlie and I lost our overwhelming preference for business ownership. Indeed, I first manifested my enthusiasm for that 80 years ago, on March 11, 1942, when I purchased three shares of Cities Services preferred stock. Their cost was $114.75 and required all of my savings. (The Dow Jones Industrial Average that day closed at 99, a fact that should scream to you: Never bet against America.)

After my initial plunge, I always kept at least 80% of my net worth in equities. My favored status throughout that period was 100% – and still is. Berkshire’s current 80%-or-so position in businesses is a consequence of my failure to find entire companies or small portions thereof (that is, marketable stocks) which meet our criteria for long- term holding.

Charlie and I have endured similar cash-heavy positions from time to time in the past. These periods are never pleasant; they are also never permanent. And, fortunately, we have had a mildly attractive alternative during 2020 and 2021 for deploying capital. Read on.

Share Repurchases

There are three ways that we can increase the value of your investment. The first is always front and center in our minds: Increase the long-term earning power of Berkshire’s controlled businesses through internal growth or by making acquisitions. Today, internal opportunities deliver far better returns than acquisitions. The size of those opportunities, however, is small compared to Berkshire’s resources.

Our second choice is to buy non-controlling part-interests in the many good or great businesses that are publicly traded. From time to time, such possibilities are both numerous and blatantly attractive. Today, though, we find little that excites us.

That’s largely because of a truism: Long-term interest rates that are low push the prices of all productive investments upward, whether these are stocks, apartments, farms, oil wells, whatever. Other factors influence valuations as well, but interest rates will always be important.

Our final path to value creation is to repurchase Berkshire shares. Through that simple act, we increase your share of the many controlled and non-controlled businesses Berkshire owns. When the price/value equation is right, this path is the easiest and most certain way for us to increase your wealth. (Alongside the accretion of value to continuing shareholders, a couple of other parties gain: Repurchases are modestly beneficial to the seller of the repurchased shares and to society as well.)

8

Periodically, as alternative paths become unattractive, repurchases make good sense for Berkshire’s owners. During the past two years, we therefore repurchased 9% of the shares that were outstanding at yearend 2019 for a total cost of $51.7 billion. That expenditure left our continuing shareholders owning about 10% more of all Berkshire businesses, whether these are wholly-owned (such as BNSF and GEICO) or partly-owned (such as Coca-Cola and Moody’s).

I want to underscore that for Berkshire repurchases to make sense, our shares must offer appropriate value. We don’t want to overpay for the shares of other companies, and it would be value-destroying if we were to overpay when we are buying Berkshire. As of February 23, 2022, since yearend we repurchased additional shares at a cost of $1.2 billion. Our appetite remains large but will always remain price-dependent.

It should be noted that Berkshire’s buyback opportunities are limited because of its high-class investor base. If our shares were heavily held by short-term speculators, both price volatility and transaction volumes would materially increase. That kind of reshaping would offer us far greater opportunities for creating value by making repurchases. Nevertheless, Charlie and I far prefer the owners we have, even though their admirable buy-and-keep attitudes limit the extent to which long-term shareholders can profit from opportunistic repurchases.

Finally, one easily-overlooked value calculation specific to Berkshire: As we’ve discussed, insurance “float” of the right sort is of great value to us. As it happens, repurchases automatically increase the amount of “float” per share. That figure has increased during the past two years by 25% – going from $79,387 per “A” share to $99,497, a meaningful gain that, as noted, owes some thanks to repurchases.

A Wonderful Man and a Wonderful Business

Last year, Paul Andrews died. Paul was the founder and CEO of TTI, a Fort Worth-based subsidiary of Berkshire. Throughout his life – in both his business and his personal pursuits – Paul quietly displayed all the qualities that Charlie and I admire. His story should be told.

In 1971, Paul was working as a purchasing agent for General Dynamics when the roof fell in. After losing a huge defense contract, the company fired thousands of employees, including Paul.

With his first child due soon, Paul decided to bet on himself, using $500 of his savings to found Tex-Tronics (later renamed TTI). The company set itself up to distribute small electronic components, and first-year sales totaled $112,000. Today, TTI markets more than one million different items with annual volume of $7.7 billion.

But back to 2006: Paul, at 63, then found himself happy with his family, his job, and his associates. But he had one nagging worry, heightened because he had recently witnessed a friend’s early death and the disastrous results that followed for that man’s family and business. What, Paul asked himself in 2006, would happen to the many people depending on him if he should unexpectedly die?

For a year, Paul wrestled with his options. Sell to a competitor? From a strictly economic viewpoint, that course made the most sense. After all, competitors could envision lucrative “synergies” – savings that would be achieved as the acquiror slashed duplicated functions at TTI.

But . . . Such a purchaser would most certainly also retain its CFO, its legal counsel, its HR unit. Their TTI counterparts would therefore be sent packing. And ugh! If a new distribution center were to be needed, the acquirer’s home city would certainly be favored over Fort Worth.

9

Whatever the financial benefits, Paul quickly concluded that selling to a competitor was not for him. He next considered seeking a financial buyer, a species once labeled – aptly so – a leveraged buyout firm. Paul knew, however, that such a purchaser would be focused on an “exit strategy.” And who could know what that would be? Brooding over it all, Paul found himself having no interest in handing his 35-year-old creation over to a reseller.

When Paul met me, he explained why he had eliminated these two alternatives as buyers. He then summed up his dilemma by saying – in far more tactful phrasing than this – “After a year of pondering the alternatives, I want to sell to Berkshire because you are the only guy left.” So, I made an offer and Paul said “Yes.” One meeting; one lunch; one deal.

To say we both lived happily ever after is an understatement. When Berkshire purchased TTI, the company employed 2,387. Now the number is 8,043. A large percentage of that growth took place in Fort Worth and environs. Earnings have increased 673%.

Annually, I would call Paul and tell him his salary should be substantially increased. Annually, he would tell me, “We can talk about that next year, Warren; I’m too busy now.”

When Greg Abel and I attended Paul’s memorial service, we met children, grandchildren, long-time associates (including TTI’s first employee) and John Roach, the former CEO of a Fort Worth company Berkshire had purchased in 2000. John had steered his friend Paul to Omaha, instinctively knowing we would be a match.

At the service, Greg and I heard about the multitudes of people and organizations that Paul had silently supported. The breadth of his generosity was extraordinary – geared always to improving the lives of others, particularly those in Fort Worth.

In all ways, Paul was a class act.

Good luck – occasionally extraordinary luck – has played its part at Berkshire. If Paul and I had not enjoyed a mutual friend – John Roach – TTI would not have found its home with us. But that ample serving of luck was only the beginning. TTI was soon to lead Berkshire to its most important acquisition.

Every fall, Berkshire directors gather for a presentation by a few of our executives. We sometimes choose the site based upon the location of a recent acquisition, by that means allowing directors to meet the new subsidiary’s CEO and learn more about the acquiree’s activities.

In the fall of 2009, we consequently selected Fort Worth so that we could visit TTI. At that time, BNSF, which also had Fort Worth as its hometown, was the third-largest holding among our marketable equities. Despite that large stake, I had never visited the railroad’s headquarters.

Deb Bosanek, my assistant, scheduled our board’s opening dinner for October 22. Meanwhile, I arranged to arrive earlier that day to meet with Matt Rose, CEO of BNSF, whose accomplishments I had long admired. When I made the date, I had no idea that our get-together would coincide with BNSF’s third-quarter earnings report, which was released late on the 22nd.

The market reacted badly to the railroad’s results. The Great Recession was in full force in the third quarter, and BNSF’s earnings reflected that slump. The economic outlook was also bleak, and Wall Street wasn’t feeling friendly to railroads – or much else.

10

On the following day, I again got together with Matt and suggested that Berkshire would offer the railroad a better long-term home than it could expect as a public company. I also told him the maximum price that Berkshire would pay.

Matt relayed the offer to his directors and advisors. Eleven busy days later, Berkshire and BNSF announced a firm deal. And here I’ll venture a rare prediction: BNSF will be a key asset for Berkshire and our country a century from now.

The BNSF acquisition would never have happened if Paul Andrews hadn’t sized up Berkshire as the right home for TTI.

Thanks

I taught my first investing class 70 years ago. Since then, I have enjoyed working almost every year with students of all ages, finally “retiring” from that pursuit in 2018.

Along the way, my toughest audience was my grandson’s fifth-grade class. The 11-year-olds were squirming in their seats and giving me blank stares until I mentioned Coca-Cola and its famous secret formula. Instantly, every hand went up, and I learned that “secrets” are catnip to kids.

Teaching, like writing, has helped me develop and clarify my own thoughts. Charlie calls this phenomenon the orangutan effect: If you sit down with an orangutan and carefully explain to it one of your cherished ideas, you may leave behind a puzzled primate, but will yourself exit thinking more clearly.

Talking to university students is far superior. I have urged that they seek employment in (1) the field and (2) with the kind of people they would select, if they had no need for money. Economic realities, I acknowledge, may interfere with that kind of search. Even so, I urge the students never to give up the quest, for when they find that sort of job, they will no longer be “working.”

Charlie and I, ourselves, followed that liberating course after a few early stumbles. We both started as part- timers at my grandfather’s grocery store, Charlie in 1940 and I in 1942. We were each assigned boring tasks and paid little, definitely not what we had in mind. Charlie later took up law, and I tried selling securities. Job satisfaction continued to elude us.

Finally, at Berkshire, we found what we love to do. With very few exceptions, we have now “worked” for many decades with people whom we like and trust. It’s a joy in life to join with managers such as Paul Andrews or the Berkshire families I told you about last year. In our home office, we employ decent and talented people – no jerks. Turnover averages, perhaps, one person per year.

I would like, however, to emphasize a further item that turns our jobs into fun and satisfaction - - - - working for you. There is nothing more rewarding to Charlie and me than enjoying the trust of individual long-term shareholders who, for many decades, have joined us with the expectation that we would be a reliable custodian of their funds.

Obviously, we can’t select our owners, as we could do if our form of operation were a partnership. Anyone can buy shares of Berkshire today with the intention of soon reselling them. For sure, we get a few of that type of shareholder, just as we get index funds that own huge amounts of Berkshire simply because they are required to do so.

11

To a truly unusual degree, however, Berkshire has as owners a very large corps of individuals and families that have elected to join us with an intent approaching “til death do us part.” Often, they have trusted us with a large – some might say excessive – portion of their savings.

Berkshire, these shareholders would sometimes acknowledge, might be far from the best selection they could have made. But they would add that Berkshire would rank high among those with which they would be most comfortable. And people who are comfortable with their investments will, on average, achieve better results than those who are motivated by ever-changing headlines, chatter and promises.

Long-term individual owners are both the “partners” Charlie and I have always sought and the ones we constantly have in mind as we make decisions at Berkshire. To them we say, “It feels good to ‘work’ for you, and you have our thanks for your trust.”

The Annual Meeting

Clear your calendar! Berkshire will have its annual gathering of capitalists in Omaha on Friday, April 29th through Sunday, May 1st. The details regarding the weekend are laid out on pages A-1 and A-2. Omaha eagerly awaits you, as do I.

I will end this letter with a sales pitch. “Cousin” Jimmy Buffett has designed a pontoon “party” boat that is now being manufactured by Forest River, a Berkshire subsidiary. The boat will be introduced on April 29 at our Berkshire Bazaar of Bargains. And, for two days only, shareholders will be able to purchase Jimmy’s masterpiece at a 10% discount. Your bargain-hunting chairman will be buying a boat for his family’s use. Join me.

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 primary basis 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 corporate 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 governance practices, 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 the law and provides basic standards for ethical and legal behavior of its employees. Human capital and resources are an integral and essential component of Berkshire’s businesses. Berkshire and its consolidated subsidiaries employed approximately 372,000 people worldwide at the end of 2021, of which approximately 77% were in the United States and 21% 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 the organizations. Given the wide variations in the nature and size of business activities, policies and practices often 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 to employees, which includes various health insurance and retirement benefits, as well as other benefits such as incentives to recognize and reward performance; wellness programs; training, learning and career advancement opportunities; and hiring practices intended to identify qualified candidates and promote diversity and inclusion in the workforce. 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 and reinsurance of life and health risks worldwide. Berkshire’s insurance subsidiaries employed approximately 50,500 people at the end of 2021. 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 that may arise 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. 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 facultative reinsurance involves coverage of specific individual underlying risks. Reinsurance contracts are further classified as quota- share 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 the indemnification 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. 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.

K-1

Insurers based in the United States (“U.S.”) are subject to regulation by their states of domicile and by those states in which they are licensed to write policies on an admitted basis. The primary focus of regulation is to assure that insurers are financially solvent and that policyholder interests are otherwise protected. States establish minimum capital levels for insurance companies and establish guidelines for permissible business and investment activities. States have the authority to suspend or revoke a company’s authority to do business as conditions warrant. States regulate the payment of dividends by insurance companies to their shareholders and other transactions with affiliates. Dividends, capital distributions and other transactions of extraordinary amounts are subject to prior regulatory approval. Insurers may market, sell and service insurance policies in the states where they are licensed. These insurers are referred to as admitted insurers. Admitted insurers are generally required to obtain regulatory approval of their policy forms and premium rates. Non-admitted insurance markets have developed to provide insurance that is otherwise unavailable through admitted insurers. Non-admitted 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 are normally 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 statutory financial statements. However, an insurer’s state of domicile has ultimate authority over these matters. In addition to its activities relating to the annual statement, the NAIC develops or adopts statutory accounting principles, model laws, regulations and programs for use by its members. Such matters deal 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 (the “Insurance Capital Standard”) based on a consolidated group approach and is also evaluating a potentially comparable group capital standard based on the aggregation of regulated entities and their underlying local capital requirements (the “Aggregation Method”). The IAIS standards address a variety of topics regarding supervision, coordination of regulators, insurance capital standards, risk management and governance. While the IAIS standards do not have legal effect, the states 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 and international insurance regulators. The Nebraska Department of Insurance acts as the lead supervisor for our group of insurance companies and chairs the Berkshire supervisory college. U.S. state regulators now require insurance groups to file an annual report, the Own Risk Solvency Assessment or ORSA, with the group’s lead supervisor. The NAIC recently adopted a group capital calculation based on methodology similar to the Aggregation Method, which leverages the NAIC’s existing Risk Based Capital standards. 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 near future. Berkshire’s insurance companies maintain capital strength at exceptionally high levels, which differentiates them from their competitors. Collectively, the combined statutory surplus of Berkshire’s U.S.-based insurers was approximately $301 billion at December 31, 2021. 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 within the Department of the Treasury a Terrorism Insurance Program (“Program”) for commercial property and casualty insurers by providing federal reinsurance of insured terrorism losses. The Program currently extends to December 31, 2027 through other Acts, most recently the Terrorism Risk Insurance Program Reauthorization Act of 2019. Hereinafter these Acts are collectively referred to as TRIA. Under TRIA, the Department of the Treasury is charged with certifying “acts of terrorism.” Coverage under TRIA occurs if the industry insured loss for certified events occurring during the calendar year exceeds $200 million in any calendar year. To be eligible for federal reinsurance, insurers must make available insurance coverage for acts of terrorism, by providing policyholders with clear and conspicuous notice of the amount of premium that will be charged for this coverage and of the federal share of any insured losses resulting from any act of terrorism. Assumed reinsurance is specifically excluded from TRIA participation. TRIA currently also 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.

K-2

In the event of a certified act of terrorism, the federal government will reimburse insurers (conditioned on their satisfaction of policyholder notification requirements) for 80% of their insured losses in excess of an insurance group’s deductible. Under the Program, the deductible is 20% of the aggregate direct subject earned premium for relevant commercial lines of business in the immediately preceding calendar year. The aggregate deductible in 2022 for Berkshire’s insurance group is expected to approximate $1.6 billion. There is also an aggregate program limit of $100 billion on the amount of the federal government coverage for each TRIA year. The extent of insurance regulation varies significantly among the countries in which our non-U.S. operations conduct business. While each country imposes licensing, solvency, auditing and financial reporting requirements, the type and extent of the requirements differ substantially. For example: • in some countries, insurers are required to prepare and file monthly and/or quarterly financial reports, and in others, only annual reports; • some regulators require intermediaries to be involved in the sale of insurance products, whereas other regulators permit direct sales contact between the insurer and the customer; • the extent of restrictions imposed upon an insurer’s use of local and offshore reinsurance vary; • policy form filing and rate regulation vary by country; • the frequency of contact and periodic on-site examinations by insurance authorities differ by country; • the scope and prescriptive requirements of an insurer’s risk management and governance framework vary significantly by country; and • regulatory requirements relating to insurer dividend policies vary by country. Significant variations can also be found in the size, structure and resources of the local regulatory departments that oversee insurance activities. Certain regulators prefer close relationships with all subject insurers and others operate a risk-based approach. Berkshire’s insurance group operates in some countries through subsidiaries and in some countries through branches of subsidiaries. Berkshire insurance subsidiaries are located in several countries, including Germany, the United Kingdom (“U.K.”), Ireland, Australia and South Africa, and also maintain branches in several other countries. Most of these foreign jurisdictions impose local capital requirements. Other legal requirements include discretionary licensing procedures, local retention of funds and records, and data privacy and protection program requirements. Berkshire’s international insurance companies are also subject to multinational application of certain U.S. laws. There are various regulatory bodies and initiatives that impact Berkshire in multiple international jurisdictions and the potential for significant effect on the Berkshire insurance group could be heightened as a result of recent 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, and Berkshire 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. Except for retroactive reinsurance and periodic payment annuity products that generate significant amounts of up-front 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 to reject inadequately priced risks. Underwriting profit is defined as earned premiums less associated incurred losses, loss adjustment expenses and underwriting and policy acquisition 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 consist of Government Employees Insurance Company, GEICO General Insurance Company, GEICO Indemnity Company, GEICO Casualty Company, GEICO Advantage Insurance Company, GEICO Choice Insurance Company, GEICO Secure Insurance Company, GEICO County Mutual Insurance Company, GEICO Texas County Mutual Insurance Company and GEICO Marine Insurance Company. The GEICO companies primarily offer private passenger automobile insurance to individuals in all 50 states and the District of Columbia. GEICO also provides insurance for motorcycles, all-terrain vehicles, recreational vehicles, boats and small commercial fleets and acts as an agent for other insurers who offer homeowners, renters, life and identity management insurance to individuals who desire insurance coverages other than those offered by GEICO.

K-3

GEICO’s 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 conducts business through regional service centers and claims adjustment and other facilities in 39 states. The automobile insurance business is highly competitive in the areas of price and service. 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. GEICO’s advertising campaigns and competitive rates contributed to a cumulative increase in voluntary policies-in- force of approximately 26.0% over the past five years. According to the most recently published A.M. Best data for 2020, the five largest automobile insurers had a combined market share in 2020 of approximately 59.7% based on written premiums, with GEICO’s market share being the second largest at approximately 13.5%. GEICO’s written premiums in 2020 were reduced by the effects of the GEICO Giveback Program implemented in response to significant reductions in claim frequencies attributable to reduced policyholder driving during the initial stages of the COVID-19 pandemic. Pandemic- related premium credit programs of other private passenger insurers may not have been reported as premium reductions, which impacts the industry data reported by A.M Best. Since the publication of that data, GEICO’s management estimates its current market share is approximately 14.2%. Seasonal variations in GEICO’s insurance business are not significant. However, extraordinary weather conditions or other factors may have a significant effect upon the frequency or severity of automobile claims. State insurance departments stringently regulate private passenger auto insurance. As a result, it is difficult for insurance companies to differentiate their products. Competition for private passenger automobile insurance, which is substantial, 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 are material assets and management protects those and other service marks through appropriate registrations. Berkshire Hathaway Primary Group—The Berkshire Hathaway Primary Group (“BH Primary”) is a collection of independently managed insurers that provide a wide variety of insurance coverages to policyholders located principally in the United States. These various operations are discussed below. National Indemnity Company (“NICO”), domiciled in Nebraska, and certain affiliates (“NICO Primary”) underwrite commercial motor vehicle and general liability insurance on an admitted basis and on an excess and surplus basis. Insurance coverages are offered nationwide primarily through insurance agents and brokers. The Berkshire Hathaway Homestate Companies (“BHHC”) is a group of insurers offering workers’ compensation, commercial auto and commercial property coverages to a diverse client base. BHHC has a national reach, with the ability to provide first-dollar and small to large deductible workers’ compensation coverage to employers in all states, except those where coverage is available only through state-operated workers’ compensation funds. NICO Primary and BHHC are each based in Omaha, Nebraska. Berkshire Hathaway Specialty Insurance (“BH Specialty”) offers commercial property, casualty, healthcare professional liability, executive and professional, surety, travel, medical stop loss and homeowner’s insurance through Berkshire Hathaway Specialty Insurance Company and other Berkshire insurance affiliates. BH Specialty writes primary and excess policies on an admitted and surplus basis in the U.S., and on a local or foreign non-admitted basis outside the U.S. BH Specialty is based in Boston, Massachusetts, with regional offices currently in several U.S. cities.

Berkshire Hathaway GUARD Insurance Companies (“GUARD”) is a group of five insurance companies that provide a full suite of commercial insurance products, as well as homeowners policies to over 350,000 small to mid-sized businesses and homeowners. These offerings are made through independent agents and retail and wholesale brokers. GUARD is based in Wilkes-Barre, Pennsylvania. MLMIC Insurance Company (“MLMIC”) has been the leading writer of medical professional liability insurance in New York State for over 40 years. MLMIC distributes the majority of its policies on a direct basis to medical and dental professionals, health care providers and hospitals. Berkshire Hathaway Reinsurance Group—Berkshire’s combined global reinsurance business, referred to as the Berkshire Hathaway Reinsurance Group (“BHRG”), offers a wide range of coverages on property, casualty, life and health risks to insurers and reinsurers worldwide. BHRG conducts business activities in 24 countries. Reinsurance business is written through NICO and certain other Berkshire insurance subsidiaries (collectively, the “NICO Group”) and General Re Corporation, domiciled in Delaware, and its subsidiaries (collectively the “General Re Group”). BHRG’s underwriting operations in the U.S. are based in Stamford, Connecticut. The type and volume of business written is dependent on market conditions, including prevailing premium rates and coverage 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. A significant portion of NICO Group’s annual reinsurance premium volume currently derives from a 20% quota-share agreement with Insurance Australia Group Limited (“IAG”) that expires July 1, 2025. IAG is a multi-line insurer in Australia, New Zealand and other Asia-Pacific countries. The General Re Group conducts 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 a lesser degree, on a facultative basis. General Re Group conducts business in North America primarily 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 conducts operations in North America from its headquarters in Stamford, Connecticut and through 12 branch offices in 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 and professional liability coverages. Such business is marketed through a select group of wholesale brokers, managing general underwriters and program administrators, and offer solutions for the unique needs of public entity, commercial and captive customers. General Re Group’s international reinsurance business is conducted on a direct basis through General Reinsurance AG, based in Cologne, Germany, and through several other subsidiaries and branches in numerous other countries. International business is also written through brokers, including Faraday Underwriting Limited (“Faraday”), a wholly-owned 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. Life/health The General Re Group also conducts a global life and health reinsurance business. In the U.S. and internationally, the General Re Group writes life, disability, supplemental health, critical illness and long-term care coverages. The life/health business is marketed on a direct basis. Life/health net premiums written by the General Re Group in 2021 were primarily in the Asia Pacific, United States and Western Europe. Berkshire Hathaway Life Insurance Company of Nebraska (“BHLN”), a subsidiary of NICO, and its affiliates write reinsurance covering various forms of traditional life insurance exposures and, on a limited basis, health insurance exposures. BHLN and affiliates are parties to contracts that reinsure certain guaranteed minimum death, income and similar benefit risks on closed-blocks of variable annuity risks under reinsurance contracts, with the most recent contract incepting in 2014.

K-5

Retroactive reinsurance NICO also periodically writes retroactive reinsurance contracts. Retroactive reinsurance contracts indemnify ceding companies against the adverse development of claims arising from loss events that have already occurred under property and casualty policies issued in prior years. Coverages under such contracts are provided 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 exceptionally large 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 and terms since loss payments may occur over decades. Normally, expected ultimate losses payable under these policies are expected to exceed premiums, thus producing underwriting losses. Nevertheless, this business is written, in part, because of the large amounts of policyholder funds generated for investment, the economic benefit of which will be reflected through investment results in future periods. Periodic payment annuity BHLN writes periodic payment annuity insurance policies and reinsures existing annuity-like obligations. Under these policies, BHLN receives upfront premiums 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 cases of other insurers, known as structured settlements. Consistent with retroactive reinsurance contracts, time-value-of-money concepts are an important factor in establishing annuity premiums, and underwriting losses are expected from the periodic accretion of time-value discounted liabilities. Investments of insurance businesses—Berkshire’s insurance subsidiaries hold significant levels of invested assets. Investment portfolios are primarily managed by Berkshire’s Chief Executive Officer. Investments include a very large portfolio of publicly traded equity securities, which are concentrated in relatively few issuers, as well as fixed maturity securities and cash and short-term investments. Generally, there are no targeted allocations by investment type or attempts to match investment asset and insurance liability durations. However, investment portfolios have historically 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 and reinsurance business (“float”). Float is the approximate amount of net policyholder funds generated through underwriting activities that is available for investment. The major components of float are unpaid losses and loss adjustment expenses, life, annuity and health benefit liabilities, 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 $91 billion at the end of 2016 to approximately $147 billion at the end of 2021. The cost of float can be measured as the net pre-tax underwriting loss as a percentage of average float. In each of the three years ending December 31, 2021, Berkshire’s consolidated cost of float was negative, as its insurance businesses produced net underwriting gains. 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 35,000 employees at the end of 2021. BNSF also operates a relatively smaller third-party logistics services business. In serving the Midwest, Pacific Northwest, Western, Southwestern and Southeastern regions and ports of the United States, BNSF 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 published prices 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’s primary routes, including trackage rights, allow it to access major cities and ports in the western and southern United States 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 the year ending December 31, 2021, approximately 38% of freight revenues were derived from consumer products, 24% from industrial products, 23% from agricultural products and 15% 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 United States Department of Transportation (“DOT”), the Occupational Safety and Health Administration (“OSHA”), 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 and services, 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 and OSHA have jurisdiction under several federal statutes over a number of safety and health aspects of rail operations, including the transportation of hazardous materials. BNSF Railway is required to transport these materials to the extent of its common carrier obligation. State agencies regulate some aspects of rail operations with respect to health and safety 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 regulation 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 to commercial or industrial companies whose activities may have resulted in discharges onto the property. Under federal (in particular, the Comprehensive Environmental Response, Compensation and Liability Act) and state statutes, BNSF may be held 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, restoration or 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’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’s GHG-emissions by 2030 from its baseline year of 2018. BNSF 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 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 and service levels. The presence of advanced, high service truck lines with expedited delivery, subsidized infrastructure and minimal 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 United States is the Union Pacific Railroad Company. Other Class I 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 Hathaway Energy Berkshire currently has a 91.1% ownership interest in Berkshire Hathaway Energy Company (“BHE”).

(“NV Energy”) is an energy holding company headquartered in Nevada, primarily consisting of two regulated utility subsidiaries, Nevada Power Company (“Nevada Power”) and Sierra Pacific Power Company (“Sierra Pacific”) (collectively, the “Nevada Utilities”). Nevada Power serves retail electric customers in southern Nevada and Sierra Pacific serves retail electric and natural gas customers in northern Nevada. The Nevada Utilities’ combined service territory’s economy includes gaming, mining, recreation, warehousing, manufacturing and governmental services. In addition to retail sales and natural gas transportation, the Nevada Utilities sell electricity and natural gas on a wholesale basis. As vertically integrated utilities, BHE’s domestic utilities own approximately 29,400 net megawatts of generation capacity in operation and under construction. The domestic utilities business is subject to seasonal variations principally related to the use of electricity for air conditioning and natural gas for heating. Typically, regulated electric revenues are higher in the summer months, while regulated natural gas revenues are higher in the winter months. The Great Britain distribution companies consist of Northern Powergrid (Northeast) plc and Northern Powergrid (Yorkshire) plc, which own a substantial electricity distribution network that delivers electricity to end-users in northeast England in an area covering approximately 10,000 square miles. The distribution companies primarily charge supply companies regulated tariffs for the use of their distribution systems. AltaLink L.P. (“AltaLink”) is a regulated electric transmission-only utility company headquartered in Calgary, Alberta. AltaLink’s high voltage transmission lines and related facilities transmit electricity from generating facilities to major load centers, cities and large industrial plants throughout its 87,000 square mile service territory. The natural gas pipelines consist of BHE GT&S, LLC (“BHE GT&S”), Northern Natural Gas Company (“Northern Natural”) and Kern River Gas Transmission Company (“Kern River”). BHE GT&S was acquired on November 1, 2020. BHE GT&S, based in Virginia, operates three interstate natural gas pipeline systems that consist of approximately 5,400 miles of natural gas transmission, gathering and storage pipelines and operates seventeen underground natural gas storage fields in the eastern region of the United States. BHE GT&S’s large underground natural gas storage assets and pipeline systems are part of an interconnected gas transmission network that provides transportation services to utilities and numerous other customers. BHE GT&S is also an industry leader in liquefied natural gas solutions through its investments in and ownership of several liquefied natural gas facilities located throughout the eastern region of the United States.

Regulatory Matters PacifiCorp, MEC and the Nevada 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 of hydroelectric facilities; and other matters. The FERC also has the enforcement authority to assess civil penalties of up to $1.4 million per day per violation of rules, regulations and orders issued under the Federal Power Act. MEC is also subject to regulation 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, BHE’s domestic 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 of customers 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 established retail electric and natural gas rates on a cost-of-service basis, designed to allow a utility the opportunity to recover what each state regulatory commission deems to be the utility’s reasonable costs of providing services, including a fair opportunity to earn a reasonable return on its investments based on its cost of debt and equity. The retail electric rates of PacifiCorp, MEC and the Nevada 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) and Northern Powergrid (Yorkshire) each charge fees for the use of their distribution systems that are controlled by a formula prescribed by the British electricity regulatory body, the Gas and Electricity Markets Authority. The current eight-year price control period runs from April 1, 2015 through March 31, 2023. AltaLink is regulated by the Alberta Utilities Commission (“AUC”), pursuant to the Electric Utilities Act (Alberta), the Public 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 with broad authority that may impact many of AltaLink’s activities, including its tariffs, rates, construction, operations and financing. 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 and storage 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 import/export facilities. Interstate natural gas pipeline companies are also subject to regulations administered by the Office of Pipeline 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 climate change, renewable portfolio standards, air and water quality, emissions performance standards, coal combustion byproduct disposal, hazardous and solid waste disposal, protected species and other environmental matters that have the 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 for noncompliance, 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 for protecting 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.

K-9

Renewable portfolio standards have been established by certain state governments and generally require electricity providers to obtain a minimum percentage of their power from renewable energy resources by a certain date. Utah, Oregon, Washington, California, Iowa and Nevada have adopted renewable portfolio standards. 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 for coordinated 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; establishes commitments by all parties to make nationally determined contributions and pursue domestic measures aimed at achieving the commitments; commits all countries to submit emissions inventories and report regularly on their emissions and progress 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 get more aggressive. In the context of the Paris Agreement, the United States agreed to reduce greenhouse gas emissions 26% to 28% by 2025 from 2005 levels. The Paris Agreement formally entered into force on November 4, 2016. The United States completed its withdrawal from the Paris Agreement on November 4, 2020. President Biden accepted the terms of the climate agreement on January 21, 2021, and the United States completed its reentry on February 19, 2021. New commitments to the Paris Agreement were announced in April 2021, with the United States pledging to cut its overall greenhouse gas emissions by 50- 52% below 2005 levels by 2030 and to reach 100% carbon pollution-free electricity by 2035. On October 10, 2017, the Environmental Protection Agency (“EPA”) issued a proposal to repeal the Clean Power Plan, which was intended to achieve an overall reduction in carbon dioxide emissions from existing fossil-fueled electric generating units of 32% below 2005 levels. On June 19, 2019, the EPA repealed the Clean Power Plan and issued the Affordable Clean Energy rule, which fully replaced the Clean Power Plan. In the Affordable Clean Energy rule, the EPA determined that the best system of emissions reduction for existing coal fueled power plants is heat rate 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 of Appeals 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 will be held in February 2022 and a decision regarding the scope of the EPA’s authority to regulate greenhouse gas emissions under the Clean Air Act is expected by June 2022. Increasingly, states are adopting legislation and regulations to reduce greenhouse gas emissions, and local governments and consumers are seeking increasing amounts of clean and renewable energy. 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 greenhouse gas (“GHG”) emissions. BHE’s primary source of GHG emissions is the generation of electricity 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 wind, solar and geothermal generation, with cumulative investments of $30.1 billion through 2021 and has retired 16 coal generation units. As a result, BHE has reduced its annual GHG emissions by about 20% from 2005 levels. BHE plans to continue investing in wind, solar and other low-carbon generation in the future and to retire an additional 16 coal generation units between 2022 and 2030 in a reliable and cost-effective manner, thereby achieving a 50% reduction in GHG emissions from 2005 levels in 2030.

Manufacturing Businesses Berkshire’s numerous and diverse manufacturing subsidiaries are grouped into three categories: (1) industrial products, (2) building products and (3) consumer products. Berkshire’s industrial products businesses manufacture components for aerospace and power generation applications, specialty chemicals, metal cutting tools, and a variety of other products primarily for industrial use. The building products group produces prefabricated and site-built residential homes, flooring products, insulation, roofing and engineered products, building and engineered components, paint and coatings and bricks and masonry products. The consumer products group manufactures recreational vehicles, alkaline batteries, various apparel products, jewelry and custom picture framing products. Information concerning the major activities of these three groups follows. Berkshire’s manufacturing businesses employed approximately 187,000 people at the end of 2021. Industrial products Precision Castparts Precision Castparts Corp. (“PCC”) manufactures complex metal components and products, provides high-quality investment castings, forgings, fasteners/fastener systems and aerostructures for critical aerospace and power and energy applications. PCC also manufactures seamless pipe for coal-fired, industrial gas turbine (“IGT”) and nuclear power plants; downhole casing and tubing, fittings and various mill forms in a variety of nickel and steel alloys for severe-service oil and gas environments; 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 to plate, 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; revert management solutions; fasteners for automotive and general industrial 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 metal components with more complex shapes, closer tolerances and finer surface finishes than parts manufactured using other methods. PCC uses this process to manufacture products for aircraft engines, IGT and other aeroderivative engines, 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 in next- generation aerospace engines. PCC uses forging processes to manufacture components for the aerospace and power generation markets, including seamless pipe for coal-fired, IGT and nuclear power plants, and downhole casings and tubing pipe for severe service oil and gas markets. PCC manufactures high-performance, nickel-based alloys used to produce forged components for aerospace and non-aerospace applications in such markets as oil and gas, chemical processing and pollution control. These titanium products are used to manufacture components for the commercial and military aerospace, power generation, energy and other industrial end markets. PCC is also a leading developer and manufacturer of highly engineered fasteners, fastener systems, aerostructures and precision components, primarily for critical aerospace applications. These products are produced for the aerospace and power and energy markets, as well as for construction, automotive, heavy truck, farm machinery, mining and construction equipment, shipbuilding, machine tools, medical equipment, appliance and recreation markets. PCC has several significant customers, including aerospace original equipment manufacturers (Boeing and Airbus) and aircraft engine manufacturer suppliers (General Electric, Rolls Royce and Pratt &Whitney). The majority of PCC’s sales are from customer orders or demand schedules pursuant to long-term agreements. Contractual terms may provide for termination by the customer, subject to payment for work performed. PCC typically does not experience significant order cancellations, although periodically it receives requests for delays in delivery schedules. Since the onset of the COVID-19 pandemic in 2020, delay requests increased, with delivery dates extending in some cases beyond 2021. The effects of the COVID-19 pandemic produced significant adverse effects on the PCC aerospace business in 2020 and 2021. The sudden and material reductions in air travel led to aircraft build rate reductions and customer destocking at extraordinary rates. The grounding of the Boeing 737 MAX also adversely impacted 2020 and 2021 and quality issues with the Boeing 787 negatively impacted 2021. Aircraft build rates have not recovered in any meaningful way. During 2020, PCC significantly reduced its worldwide workforce by about 40% to help align operations to reduced aircraft build rates. The restructuring actions taken began to improve margins in late 2020 and further margin improvements were achieved in 2021.

K-11

PCC is subject to substantial competition in all of its markets. Components and similar products may be produced by competitors, who use either the same types of manufacturing processes as PCC or other processes. Although PCC believes its manufacturing processes, technology and experience provide advantages to its customers, 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. Despite intense competition, 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 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 world politics, labor relations between the metal producers and their workforces and inflation. 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 greenhouse gas 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.

Lubrizol uses many specialty and commodity chemical raw materials in its manufacturing processes. Raw materials are primarily feedstocks derived from petroleum and petrochemicals and, generally, are obtainable from several sources. The materials that Lubrizol chooses to purchase from a single source typically are subject to long-term supply contracts to ensure supply reliability. Lubrizol operates its business on a global basis through more than 100 offices, laboratories, production facilities and warehouses on six continents, the most significant of which are North America, Europe, Asia and South America. Lubrizol markets its products worldwide through direct sales, sales agents and distributors. Lubrizol’s customers principally consist of major global and regional oil companies and industrial and consumer products companies. Some of Lubrizol’s largest customers also may be suppliers. During 2021, no single customer accounted for more than 10% of Lubrizol’s consolidated revenues. In 2021, the COVID-19 pandemic continued to have an adverse effect on many of the markets that Lubrizol serves, as did worldwide supply chain disruptions, affecting both the availability of raw materials and fulfillment of customer orders. In addition, the occurrence and duration of the February 2021 winter storms and freezing temperatures in Texas significantly interrupted operations at Lubrizol’s manufacturing facilities. Lubrizol expends significant capital to ensure the safety of its employees and the communities where it operates, as well as delivering on its commitments to operational excellence and cybersecurity. Lubrizol also makes significant capital investments to ensure reliable supply and compliance with regulations governing its operations, while reducing their environmental footprint.

K-12

Lubrizol is subject to foreign, federal, state and local laws to protect the environment, limit manufacturing waste and emissions, ensure product and employee safety and regulate trade. While the company believes that its policies, practices and procedures are designed to limit the risks of non-compliance with laws and consequent financial liability, it experienced a fire at one of its chemical manufacturing facilities in 2019, which resulted in significant cleanup and remediation costs. Lubrizol also suffered a fire in 2021 that resulted in a total loss of its grease manufacturing facility. The operation of chemical manufacturing plants entails ongoing environmental and other risks, and significant capital expenditures, costs or liabilities could be incurred in the future.

The availability of raw materials is adequate, but costs are impacted by petro-chemical and natural gas price changes. Raw material cost changes are periodically factored into selling prices to customers. The soft floor covering industry is highly competitive with only a handful of key players domestically where the majority of Shaw’s business occurs. There are numerous manufacturers, domestically and internationally, that are engaged in hard surface floor covering production, distribution and sales. According to industry estimates, carpet accounts for approximately 44% of the total United States consumption of all flooring types. The principal competitive measures within the floor covering industry are quality, style, price and service.

Fiberglass is made from earthen raw materials and recycled glass, together with agents to bind many of its glass fibers. JM’s products also contain materials other than fiberglass, including various chemical and petrochemical-based materials used in roofing and other specialized products. JM uses recycled material when available and suitable to satisfy the broader needs of its customers. The raw materials used in these various products are generally readily available in sufficient quantities from various sources to maintain and expand its current production levels. JM identifies and strives to mitigate risk with respect to material applicable laws and regulations, including environmental laws and regulations. JM’s operations are subject to a variety of federal, state and local environmental laws and regulations, which regulate or impose liability for the discharge of materials into the air, land and water and govern the use and disposal of hazardous substances and use of chemical substances. The most relevant of the federal laws are the Federal Clean Air Act, the Clean Water Act, the Toxic Substances Control Act, the Resource Conservation and Recovery Act and the Comprehensive Environmental Response, Compensation and Liability Act, which are administered by the EPA.

Through this agreement, these Ace stores are afforded the opportunity to carry a full line premium assortment of Benjamin Moore products or a streamlined offering of Regal® Select and ben®, or ben® only branded products.

In addition, Benjamin Moore operates an online “pick up in store” program, which allows consumers to place orders via an e-commerce site or, for national accounts and government agencies, via its customer information center. These orders may be picked up at the customer’s nearest retailer or delivered. For national accounts, drop-ship orders can be fulfilled by Benjamin Moore if a minimum gallon threshold is met. Benjamin Moore competes with numerous manufacturers, distributors and paint, coatings and related products retailers. Product quality, product innovation, breadth of product line, technical expertise, service and price determine the competitive advantage. Competitors include other paint and decorating stores, mass merchandisers, home centers, independent hardware stores, hardware chains and manufacturer-operated direct outlets, such as Sherwin-Williams Company, PPG Industries, Inc., The Valspar Corporation, The Home Depot, Inc. and Lowe’s Companies, Inc. The most significant raw materials in Benjamin Moore products are titanium dioxide, monomers, polymers and pigments. Historically, these materials have been generally available, with pricing and availability subject to fluctuation. In 2021, raw material supply constraints and increased customer demand for products prevailed and disrupted Benjamin Moore’s ability to build inventory. A major winter storm that impacted the Gulf Coast region of the United States in February of 2021 caused substantial supply chain disruptions for Benjamin Moore, which contributed to significant inflation in manufacturing costs. Benjamin Moore undertakes to comply with applicable regulations relating to protection of the environment and workers’ safety and products meet or exceed environmental standards. Benjamin Moore has certain known past environmental matters, which are subject to on-going monitoring and/or remediation efforts.

K-17

The brick industry is subject to the EPA Maximum Achievable Control Technology Standards (“MACT”). As required under the 1990 Clean Air Act, the EPA developed a list of source categories that require the development of National Emission Standards for Hazardous Air Pollutants, which are also referred to as MACT Standards (“Rule”). Key elements of the MACT Rule include emission limits established for certain hazardous air pollutants and acidic gases. Acme’s brick plants are in compliance with the current Rule.

U.S.-grown cotton fiber and U.S.-manufactured polyester fiber are the main raw materials used in manufacturing FOL’s products. Historically, fibers have been purchased from a limited number of third parties. In 2015, FOL entered into an agreement with one key supplier to provide the majority of its yarn spinning/raw material conversion services. As a result, yarn production was primarily with one supplier. Supply chain issues related to the COVID pandemic including labor shortage at suppliers, yarn shortages, and price inflation in raw materials and freight resulted in FOL utilizing alternative sources of raw materials and yarn in 2021. Further, FOL has contracted with an additional supplier for a significant portion of FOL’s yarn spinning/raw material conversion services that is scheduled to begin in July 2022. If relationships with suppliers cannot be maintained or delays occur in obtaining alternative sources of supply, production and operating results can be adversely affected.

Berkshire Hathaway Automotive Berkshire Hathaway Automotive, Inc. (“BHA”) and its affiliates is one of the largest automotive retailers in the United States, currently operating 105 new vehicle franchises through 82 dealerships located primarily in major metropolitan markets in the United States. The dealerships sell new and used vehicles, vehicle maintenance and repair services, extended service contracts, vehicle protection products and other aftermarket products.

BHA operates 28 collision centers directly connected to the dealerships’ operations and owns and operates two auto auctions and a fluid maintenance products distribution company. Dealership operations are highly concentrated in the Arizona and Texas markets, with approximately 75% of dealership-related 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. Approximately 90% of BHA’s annual revenues are from dealerships representing these manufacturers. 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 pricing transparency available via the Internet, and the fact that franchised dealers acquire vehicles from the manufacturers on the same terms irrespective of volume, the location and quality of the dealership facility, customer service and transaction speed are key differentiators in attracting customers. BHA’s overall relationships with the automobile manufacturers are governed by framework agreements. The framework agreements contain provisions relating to the management, operation, acquisition and ownership structure of BHA’s 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.

K-21

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. BHA also develops, underwrites and administers various vehicle protection plans as well as life and accident and health insurance plans sold to consumers through BHA’s dealerships and third-party dealerships.

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 cyber, biological, nuclear or chemical attack could produce significant losses to our worldwide operations. Our business operations could be adversely affected from such acts through the loss of human resources or destruction of production facilities and information systems. We share the risk with all businesses. Cyber security 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-of- service attacks and other cyber-attacks and we expect to be subject to similar attacks in the future as such attacks become more sophisticated 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 and critical 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 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 business interruptions, 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. 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 the Board of Directors and Chief Executive Officer, age 91, in consultation with Charles T. Munger, Vice Chairman of the Board of Directors, age 98. In 2018, Berkshire’s Board of Directors appointed Mr. Gregory Abel as 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 be a 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 with the outstanding managers running our numerous and highly diversified operating units helps to mitigate this risk.

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 business activities of our operating subsidiaries and to manage changes in future business operations due to changing business or regulatory environments. Our operating subsidiaries also need qualified and competent personnel in executing their business plans and serving their customers, suppliers and other stakeholders. Our inability to recruit and retain qualified and competent managers and personnel could negatively affect the operating results, financial condition and 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 equity securities. 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 fair values of these investments will produce significant declines in the statutory surplus of our insurance business. Our large statutory surplus is a competitive advantage, and a long-term material decline could have an adverse effect on our claims- paying 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 our businesses 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 and enhancing 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 to access 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 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 outbreaks, including COVID-19, could hurt our operating businesses. The outbreak of COVID-19 has adversely affected, and in the future it or other epidemics, pandemics or outbreaks may adversely affect, our operations, including our equity securities portfolio. This is or may be due to closures or restrictions requested or mandated by governmental 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 regulation of banks and other major financial institutions, products and environmental and global-warming matters. These initiatives impact all of our businesses, albeit in varying ways. Increased regulatory compliance costs could have a significant negative impact on our operating businesses, as well as on the businesses in which we have a significant, but not controlling economic interests. We cannot predict whether such initiatives will have a material adverse impact on our consolidated 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 penalties.

K-25

Risks unique to our regulated businesses Our tolerance for risk in our 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 and 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 above $10 billion. However, despite our efforts, it is possible that losses could manifest in ways that we do not anticipate and that our risk mitigation strategies are not designed to address. Additionally, various provisions of our policies, such as limitations or exclusions from coverage, negotiated to limit our risks, may not be enforceable in the manner we intend. Our tolerance for significant insurance losses may result in lower reported earnings in a future period. The degree of estimation error inherent in the process of estimating property and casualty insurance loss reserves may result in significant underwriting losses. 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 that liabilities for unpaid losses are adequate, we will not know whether these liabilities or the premiums charged for the coverages provided were sufficient until well after the balance sheet date. Estimating insurance claim costs is inherently imprecise. Our estimated unpaid losses arising under contracts covering property and casualty insurance risks are large ($125 billion at December 31, 2021), and a small percentage increase to those liabilities can result in materially lower reported earnings. Climate change may impact our businesses. Climate change could cause increases in hurricanes, floods, wildfires, and other risks that could produce losses affecting our businesses. Also, failure to comply with new or existing regulations or reinterpretations of existing regulations relating to climate change could have a significant adverse effect on our financial results. 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 capital that 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. Our railroad business conducted through BNSF is also subject to a significant number of laws and regulations with respect 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 pose significant 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 source of fuel in generating electricity or alternate fuels, such as natural gas, or displace coal on a competitive basis, 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 of operations, 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 and subject 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 and integrity 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 and water quality, renewable portfolio standards, emissions performance standards, climate change, coal combustion byproduct disposal, hazardous and solid waste disposal, protected species 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 so that 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 and distribution systems to meet their customers’ needs and reliability criteria. Additionally, system assets may need to be operational for long periods of time in order 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 funded through 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.

Legal Proceedings Berkshire and its subsidiaries 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. 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 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.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations Results of Operations Net earnings attributable to Berkshire Hathaway shareholders for each of the past three years are disaggregated in the table that follows. Amounts are after deducting income taxes and exclude earnings attributable to noncontrolling interests (in millions). 2021 2020 2019 Insurance – underwriting $ 728 $ 657 $ 325 Insurance – investment income 4,807 5,039 5,530 Railroad 5,990 5,161 5,481 Utilities and energy 3,495 3,091 2,840 Manufacturing, service and retailing 11,120 8,300 9,372 Investment and derivative gains/losses 62,340 31,591 57,445 Other* 1,315 (11,318) 424 Net earnings attributable to Berkshire Hathaway shareholders $ 89,795 $ 42,521 $ 81,417

∗ Includes goodwill and indefinite-lived intangible asset impairment charges of $259 million in 2021, $11.0 billion in 2020 and $435 million in 2019, which includes our share of charges recorded by Kraft Heinz. Through our subsidiaries, we engage in numerous diverse business activities. We manage our operating businesses on an 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 the selection of the Chief Executive to head each of the operating businesses. The business segment data (Note 25 to the accompanying Consolidated Financial Statements) should be read in conjunction with this discussion. The COVID-19 pandemic negatively affected most of our businesses beginning in March of 2020, with the effects to date ranging from relatively minor to severe. Earnings of most of our manufacturing, service and retailing businesses declined considerably, and in certain instances severely, in the second quarter of 2020. Over the second half of 2020 and continuing in 2021, many of these businesses experienced significant recoveries in revenues and earnings, in some instances exceeding pre-pandemic levels. However, many of our businesses were negatively affected by ongoing global supply chain disruptions, including those attributable to major winter storms and a hurricane in North America, which contributed to higher input costs. We cannot reliably predict future economic effects of the pandemic or when business activities at our operations will completely normalize. Nor can we predict how these events will alter the future consumption patterns of consumers and businesses we serve. Our insurance businesses generated after-tax earnings from underwriting of $728 million in 2021, $657 million in 2020 and $325 million in 2019. In each year, we generated underwriting earnings from primary insurance and underwriting losses from reinsurance. Insurance underwriting results included after-tax losses from significant catastrophe events of approximately $2.3 billion in 2021, $750 million in 2020 and $800 million in 2019. Underwriting results in 2021 were favorably impacted by reductions in incurred losses for prior accident years under property and casualty contracts. Underwriting results in 2021 were negatively impacted by reductions in earned premium from the GEICO Giveback program, higher private passenger auto claims frequencies and severities estimates and higher losses in the life reinsurance business. Underwriting results in 2020 included the effects of the pandemic, arising from premium reductions from the GEICO Giveback program, reduced claims frequencies for private passenger automobile insurance and increased loss estimates for certain commercial insurance and property and casualty reinsurance business. After-tax earnings from insurance investment income in 2021 decreased 4.6% compared to 2020 and declined 8.9% in 2020 versus 2019. Earnings in 2021 and 2020 were negatively affected by declines in interest rates on our substantial holdings of cash and U.S. Treasury Bills.

Management’s Discussion and Analysis (Continued) Results of Operations (Continued) After-tax earnings of our railroad business in 2021 rose 16.1% compared to 2020 and decreased 5.8% in 2020 compared to 2019. The earnings increase in 2021 reflected overall higher freight volumes, higher average revenue per car/unit and improved productivity, partly offset by higher average fuel prices and volume related costs. Earnings in 2020 reflected lower railroad operating revenues from lower shipping volumes, attributable to the negative effects of the COVID- 19 pandemic, partly offset by lower operating costs and the effects of productivity improvements. After-tax earnings of our utilities and energy business in 2021 increased 13.1% versus 2020 and increased 8.8% in 2020 compared to 2019. The increase in 2021 included higher earnings from the utilities and natural gas pipelines businesses, including the effects of a business acquisition, and from the real estate brokerage business, while the earnings increase in 2020 reflected increased tax benefits from renewable energy and increased earnings from the real estate brokerage business. Earnings in 2021 from our manufacturing, service and retailing businesses increased 34.0% versus 2020 and declined 11.4% in 2020 versus 2019. Many of our businesses generated significantly higher earnings in 2021 compared to 2020. While customer demand for products was relatively high during the year, several of our businesses experienced higher materials, freight and other input costs attributable to ongoing disruptions in global supply chains. The effects of the COVID- 19 pandemic have varied among our businesses relative to significance and duration. Other earnings included after-tax goodwill and indefinite-lived intangible asset impairment charges of $259 million in 2021, $11.0 billion in 2020 and $435 million in 2019. Such amounts included our share of impairment charges recorded by Kraft Heinz. Approximately $9.8 billion of the charges in 2020 were attributable to impairments of goodwill and indefinite- lived intangible assets recorded in connection with Berkshire’s acquisition of Precision Castparts in 2016. Other earnings in 2021 also included after-tax foreign exchange rate gains of $955 million and after-tax losses of $764 million in 2020 related to non-U.S. Dollar denominated debt issued by Berkshire and its U.S.-based finance subsidiary, Berkshire Hathaway Finance Corporation (“BHFC”). Investment and derivative gains/losses in each of the three years presented predominantly derived from our investments in equity securities and included significant net unrealized gains from market price changes. We believe that investment and derivative gains/losses, whether realized from dispositions or unrealized from changes in market prices of equity securities, are generally meaningless in understanding our reported quarterly or annual 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. 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 of Berkshire’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 not meaningful 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. Generally, we consider incurred losses exceeding $100 million from a current year catastrophic event to be significant. The significant catastrophe events in 2021 included Hurricane Ida and floods in Europe in the third quarter, as well as Winter Storm Uri in the first quarter. Changes in estimates for unpaid losses and loss adjustment expenses, including amounts established for occurrences in prior years, can also significantly affect our periodic underwriting results. Unpaid loss estimates, including estimates under retroactive reinsurance contracts, were approximately $125 billion as of December 31, 2021. Our periodic underwriting results may also include significant foreign currency transaction gains and losses arising from the changes in the valuation of non-U.S. Dollar denominated liabilities of our U.S. based insurance subsidiaries due to foreign currency exchange rate fluctuations.

Management’s Discussion and Analysis (Continued) Insurance—Underwriting (Continued) Underwriting results of certain of our commercial insurance and reinsurance businesses were negatively affected in 2021 and 2020 by estimated losses and costs associated with the COVID-19 pandemic, including incremental provisions for claims and uncollectible premiums and incremental operating costs to maintain customer service levels. The effects of the pandemic on future periods may be affected by judicial rulings and regulatory and legislative actions pertaining to insurance coverage and claims and by its effects on general economic activity, which we cannot reasonably estimate at this time. We provide primary insurance and reinsurance products covering property and casualty risks, as well as life and health risks. Our insurance and reinsurance businesses are GEICO, Berkshire Hathaway Primary Group and Berkshire Hathaway Reinsurance Group. Underwriting results of our insurance businesses are summarized below (dollars in millions). 2021 2020 2019 Pre-tax underwriting earnings (loss): GEICO $ 1,259 $ 3,428 $ 1,506 Berkshire Hathaway Primary Group 607 110 383 Berkshire Hathaway Reinsurance Group (930) (2,700) (1,472) Pre-tax underwriting earnings 936 838 417 Income taxes and noncontrolling interests 208 181 92 Net underwriting earnings $ 728 $ 657 $ 325 Effective income tax rate 22.2% 21.5% 24.2%

GEICO GEICO writes private passenger automobile insurance, offering coverages to insureds in all 50 states and the District of Columbia. GEICO markets its policies mainly by direct response methods where most customers apply for coverage directly to the company via the Internet or over the telephone. A summary of GEICO’s underwriting results follows (dollars in millions). 2021 2020 2019 Amount % Amount % Amount % Premiums written $ 38,395 $ 34,928 $ 36,016 Premiums earned $ 37,706 100.0 $ 35,093 100.0 $ 35,572 100.0 Losses and loss adjustment expenses 30,999 82.2 26,018 74.1 28,937 81.3 Underwriting expenses 5,448 14.5 5,647 16.1 5,129 14.5 Total losses and expenses 36,447 96.7 31,665 90.2 34,066 95.8 Pre-tax underwriting earnings $ 1,259 $ 3,428 $ 1,506

GEICO’s pre-tax underwriting earnings in 2021 and 2020 were significantly affected by changes in average claims frequencies. Beginning in the first quarter of 2020 and continuing through the first quarter of 2021, average claims frequencies were significantly below historical levels from the effects of less driving by policyholders during the COVID-19 pandemic. These effects were partially offset by higher average claims severities and lower premiums earned from the GEICO Giveback program, which provided for a 15% premium credit to all voluntary auto and motorcycle new policies or policies renewing between April 8, 2020 and October 7, 2020. Starting in the second quarter of 2021, average claims frequencies began to increase as driving by policyholders increased. In addition, average property claims severities increased due to increases in used vehicle valuations.

Management’s Discussion and Analysis (Continued) Insurance—Underwriting (Continued) GEICO (Continued) 2021 versus 2020 Premiums written in 2021 increased $3.5 billion (9.9%) compared to 2020, which included a reduction of approximately $2.9 billion attributable to the GEICO Giveback program. Premiums earned in 2021 increased $2.6 billion (7.4%) compared to 2020. The GEICO Giveback Program reduced earned premiums by approximately $2.5 billion in 2020 with the remainder of the impact included in 2021. Voluntary auto policies-in-force in 2021 were slightly higher compared to 2020. Losses and loss adjustment expenses increased $5.0 billion (19.1%) compared to 2020. GEICO’s ratio of losses and loss adjustment expenses to premiums earned (the “loss ratio”) increased 8.1 percentage points compared to 2020. The increase in the loss ratio reflected an increase in average claims frequencies and severities and higher losses from significant catastrophe events, partially offset by increased reductions of ultimate estimated losses for claims occurring in prior years. Claims frequencies in 2021 were higher for all coverages, including property damage and bodily injury (thirteen to fourteen percent range), personal injury (sixteen to seventeen percent range) and collision (twenty-one to twenty-two percent range). Average claims severities in 2021 were also higher for property damage coverage (two to three percent range), collision coverage (fifteen to sixteen percent range) and bodily injury coverage (eight to ten percent range). Ultimate claim loss estimates for claims occurring in prior years were reduced approximately $1.8 billion in 2021 and $253 million in 2020, which produced corresponding reductions in losses and loss adjustment expenses. Losses incurred attributable to Hurricane Ida in 2021 were $375 million, while losses in 2020 included $81 million attributable to Hurricanes Laura and Sally and U.S. wildfires. Underwriting expenses decreased $199 million (3.5%) compared to 2020, reflecting lower advertising expenses. GEICO’s expense ratio (underwriting expenses to premiums earned) decreased 1.6 percentage points in 2021, reflecting lower nominal expenses and higher premiums earned. 2020 versus 2019 Premiums written and earned in 2020 decreased $1.1 billion (3.0%) and $479 million (1.3%), respectively, compared to 2019. The GEICO Giveback program reduced premiums written $2.9 billion and premiums earned $2.5 billion in 2020. Voluntary auto policies-in-force increased approximately 820,000 during 2020. Losses and loss adjustment expenses in 2020 decreased $2.9 billion (10.1%) compared to 2019. GEICO’s loss ratio was 74.1%, a decrease of 7.2 percentage points compared to 2019. The decrease in the loss ratio reflected declines in claims frequencies, partly offset by increases in claims severities and the impact of lower premiums earned attributable to the GEICO Giveback program. Claims frequencies in 2020 were lower for property damage, bodily injury and personal injury protection coverages (twenty-eight to thirty percent range) and collision coverage (twenty-three to twenty-four percent range) compared to 2019. Average claims severities in 2020 were higher for property damage and collision coverages (eight to ten percent range) and bodily injury coverage (twelve to thirteen percent range). Losses and loss adjustment expenses included net reductions of $253 million in 2020 for decreases in the ultimate loss estimates for claims occurring in prior years compared to net increases of $42 million in 2019. Losses incurred included $81 million in 2020 from Hurricanes Laura and Sally and U.S. wildfires. There were no losses from significant catastrophe events in 2019. Underwriting expenses in 2020 increased $518 million (10.1%) compared to 2019, reflecting higher employee-related, advertising and technology costs, partly offset by lower premium taxes. GEICO’s expense ratio in 2020 was 16.1%, an increase of 1.6 percentage points compared to 2019. The expense ratio increase was primarily attributable to the decline in earned premiums from the GEICO Giveback program.

Management’s Discussion and Analysis (Continued) Insurance—Underwriting (Continued) Berkshire Hathaway Primary Group The Berkshire Hathaway Primary Group (“BH Primary”) provides a variety of commercial insurance solutions, including healthcare professional liability, workers’ compensation, automobile, general liability, property and specialty coverages for small, medium and large clients. BH Primary’s larger insurers include Berkshire Hathaway Specialty Insurance (“BH Specialty”), Berkshire Hathaway Homestate Companies (“BHHC”), MedPro Group, Berkshire Hathaway GUARD Insurance Companies (“GUARD”), National Indemnity Company (“NICO Primary”) and U.S. Liability Insurance Company (“USLI”). A summary of BH Primary underwriting results follows (dollars in millions). 2021 2020 2019 Amount % Amount % Amount % Premiums written $ 12,595 $ 10,212 $ 9,843 Premiums earned $ 11,575 100.0 $ 9,615 100.0 $ 9,165 100.0 Losses and loss adjustment expenses 8,107 70.0 7,129 74.1 6,336 69.1 Underwriting expenses 2,861 24.8 2,376 24.7 2,446 26.7 Total losses and expenses 10,968 94.8 9,505 98.8 8,782 95.8 Pre-tax underwriting earnings $ 607 $ 110 $ 383

Premiums written increased $2.4 billion (23.3%) in 2021 compared to 2020, reflecting increases from BH Specialty (36%), MedPro Group (16%), NICO Primary (25%), GUARD (7%), BHHC (5%) and USLI (20%). The increases were across multiple coverages and occurred in several markets. Premiums written increased $369 million (3.7%) in 2020 compared to 2019, reflecting increased premiums written from BH Specialty (34%) and MedPro Group (9%), partially offset by a 13% decrease in premiums written by our other primary insurers. The decline in volume by our other primary insurers was primarily due to lower workers’ compensation and commercial automobile volumes and the effect of the divestiture of Applied Underwriters in October 2019. BH Primary’s loss ratios were 70.0% in 2021, 74.1% in 2020 and 69.1% in 2019. Losses and loss adjustment expenses attributable to significant catastrophe events were $402 million in 2021 from Hurricane Ida and Winter Storm Uri and $207 million in 2020 from Hurricanes Laura and Sally and U.S. wildfires. Losses and loss adjustment expenses were reduced $631 million in 2021, $265 million in 2020 and $499 million in 2019 for net reductions in estimated ultimate liabilities for prior years’ loss events. Losses in 2020 also included increased liabilities of $167 million attributable to the pandemic. BH Primary insurers write significant levels of commercial and professional liability and workers’ compensation insurance and the related claim costs may be subject to high severity and long claim-tails. Accordingly, we could experience significant increases in claims liabilities in the future attributable to higher-than-expected claim settlements, adverse litigation outcomes or judicial rulings and other factors not currently anticipated. Underwriting expenses increased $485 million (20.4%) in 2021 compared to 2020, reflecting the increase in business, changes in business mix and the costs associated with new product development. The expense ratio in 2021 was relatively unchanged versus 2020. The expense ratio in 2020 declined 2.0 percentage points compared to 2019 and reflected changes in business mix and the impact of the Applied Underwriters divestiture. Berkshire Hathaway Reinsurance Group The Berkshire Hathaway Reinsurance Group (“BHRG”) offers excess-of-loss and quota-share reinsurance coverages on property and casualty risks to insurers and reinsurers worldwide through several subsidiaries, led by National Indemnity Company (“NICO”), General Reinsurance Corporation and General Reinsurance AG. 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 periodically assume property and casualty risks under retroactive reinsurance contracts written through NICO. In addition, we write periodic payment annuity contracts through BHLN.

Management’s Discussion and Analysis (Continued) Insurance—Underwriting (Continued) Berkshire Hathaway Reinsurance Group (Continued) Generally, we strive to generate underwriting profits. However, time-value-of-money concepts are important elements in establishing prices for retroactive reinsurance and periodic payment annuity businesses due to the expected long durations of the claim liabilities. We expect to incur pre-tax underwriting losses from such businesses, primarily through deferred charge amortization and discount accretion charges. We receive premiums at the inception of these contracts, which are then available for investment. A summary of BHRG’s premiums and pre-tax underwriting results follows (dollars in millions). Pre-tax underwriting Premiums written Premiums earned earnings (loss) 2021 2020 2019 2021 2020 2019 2021 2020 2019 Property/casualty $ 14,149 $ 13,295 $ 10,428 $ 13,740 $ 12,214 $ 9,911 $ 667 $ (799) $ 16 Life/health 5,621 5,848 4,963 5,648 5,861 4,869 (421) (18) 159 Retroactive reinsurance 136 38 684 136 38 684 (782) (1,248) (1,265) Periodic payment annuity 658 566 863 658 566 863 (508) (617) (549) Variable annuity 15 14 14 15 14 14 114 (18) 167 $ 20,579 $ 19,761 $ 16,952 $ 20,197 $ 18,693 $ 16,341 $ (930) $ (2,700) $ (1,472) Property/casualty A summary of property/casualty reinsurance underwriting results follows (dollars in millions). 2021 2020 2019 Amount % Amount % Amount % Premiums written $ 14,149 $ 13,295 $ 10,428 Premiums earned $ 13,740 100.0 $ 12,214 100.0 $ 9,911 100.0 Losses and loss adjustment expenses 9,878 71.9 9,898 81.0 7,313 73.8 Underwriting expenses 3,195 23.2 3,115 25.5 2,582 26.0 Total losses and expenses 13,073 95.1 13,013 106.5 9,895 99.8 Pre-tax underwriting earnings (loss) $ 667 $ (799) $ 16

Premiums written increased $854 million (6.4%) in 2021 compared to 2020, primarily attributable to net new business, increased participations and improved prices on renewals and favorable currency translation effects. The increase was primarily attributable to property coverages. Premiums written increased $2.9 billion (27.5%) in 2020 compared to 2019. The increase was primarily attributable to net new business and increased participations on renewals. Losses and loss adjustment expenses were relatively unchanged in 2021 compared to 2020, while the loss ratio decreased 9.1 percentage points. The loss ratio was 71.9% in 2021, 81.0% in 2020 and 73.8% in 2019. Losses incurred arising from significant catastrophe events in 2021 (Hurricane Ida, flooding in Europe and Winter Storm Uri) were $2.1 billion, which were partially offset by reductions in estimated ultimate liabilities for losses occurring in prior years of $718 million. Losses incurred in 2020 included $667 million from significant catastrophe events (Hurricanes Laura and Sally and U.S. wildfires), losses attributable to the COVID-19 pandemic of $964 million and increases in estimated ultimate liabilities for losses occurring in prior years of $162 million. Incurred losses from significant catastrophe events during 2019 were $1.0 billion and derived from Typhoons Faxai and Hagibis and various U.S. and non-U.S. wildfires, which were partially offset by reductions in estimated ultimate liabilities for losses occurring in prior years of $295 million. Underwriting expenses are primarily commissions and brokerage costs. The expense ratio in 2021 decreased 2.3 percentage points compared to 2020, primarily attributable to changes in business mix and foreign currency effects. Underwriting expenses increased $533 million (20.6%) in 2020 compared to 2019, reflecting the increase in premiums earned.

Management’s Discussion and Analysis (Continued) Insurance—Underwriting (Continued) Berkshire Hathaway Reinsurance Group (Continued) Life/health A summary of our life/health reinsurance underwriting results follows (dollars in millions). 2021 2020 2019 Amount % Amount % Amount % Premiums written $ 5,621 $ 5,848 $ 4,963 Premiums earned $ 5,648 100.0 $ 5,861 100.0 $ 4,869 100.0 Life and health insurance benefits 4,933 87.3 4,883 83.3 3,800 78.0 Underwriting expenses 1,136 20.2 996 17.0 910 18.7 Total benefits and expenses 6,069 107.5 5,879 100.3 4,710 96.7 Pre-tax underwriting earnings (loss) $ (421) $ (18) $ 159 Life/health premiums written decreased $227 million (3.9%) in 2021 compared to 2020. Premiums written in 2020 included $710 million from a contract that covered U.S. health risks that incepted in the fourth quarter of 2019 and did not renew in 2021. Otherwise, premiums written in 2021 increased 9.4% versus 2020, primarily due to volume growth in the Asia Pacific region and favorable foreign currency translation effects. Underwriting results in 2021 were negatively affected by significant increases in mortality in the U.S., South Africa, India and Latin America, attributable to the pandemic. Life/health premiums written increased $885 million (17.8%) in 2020 compared to 2019. Approximately $480 million of the increase was attributable to the contract covering U.S. health insurance risks, and the remainder of the increase was primarily from volume growth in Asia and Europe. Underwriting earnings in 2020 were negatively affected by increased life benefits from COVID-19-related claims and from increased liabilities from changes in underlying assumptions in estimating disability benefit liabilities in Australia, which were mostly offset by lower other life claims and reduced losses from U.S. long-term care business that is in run-off. Results in 2019 included a one-time pre-tax underwriting gain of $163 million attributable to an amendment of a yearly renewable term life contract. Retroactive reinsurance Pre-tax underwriting losses in each year derived from the amortization of deferred charges and changes in the estimated timing and amounts of future claim payments. Underwriting results also include foreign currency exchange gains and losses from the effects of changes in foreign currency exchange rates on non-U.S. Dollar denominated liabilities of our U.S. subsidiaries. Underwriting results included pre-tax foreign currency gains of $56 million in 2021 and losses of $139 million in 2020 and $76 million in 2019. Pre-tax underwriting losses before foreign currency gains/losses were $838 million in 2021, $1.1 billion in 2020 and $1.2 billion in 2019. Estimated ultimate claim liabilities for contracts written in prior years were reduced $974 million in 2021 and $399 million in 2020. After adjustments to the related unamortized deferred charges from changes in the estimated timing and amount of the future claim payments, such reductions produced pre-tax underwriting earnings of $142 million in 2021 and $230 million in 2020. Gross unpaid losses assumed under retroactive reinsurance contracts were $38.3 billion at December 31, 2021, a decline of $2.7 billion since December 31, 2020. The decline was primarily attributable to paid claims of approximately $1.9 billion and the reduction in estimated ultimate claim liabilities. Unamortized deferred charges related to retroactive reinsurance contracts were $10.6 billion at December 31, 2021, a decline of $1.8 billion since December 31, 2020, attributable to the effects of the changes in the estimated timing and amount of the future claim payments and periodic amortization. Deferred charge amortization will be included in underwriting earnings over the expected remaining claims settlement periods.

Management’s Discussion and Analysis (Continued) Insurance—Underwriting (Continued) Berkshire Hathaway Reinsurance Group (Continued) Periodic payment annuity Periodic payment annuity premiums earned increased $92 million (16.3%) in 2021 compared to 2020, which decreased $297 million (34.4%) versus 2019. Periodic payment annuity business is both price and demand sensitive. Our premium volumes in 2021 and 2020 were affected by pandemic-related delays in underlying claim settlements, which reduced the supply of available business. Our volumes written may also change rapidly due to changes in prices, which are affected by prevailing interest rates, the perceived risks and durations associated with the expected annuity payments, as well as the level of competition. Periodic payment annuity contracts normally produce pre-tax underwriting losses deriving from the recurring discount accretion of annuity liabilities. Underwriting results also include gains or losses from the effects of changes in mortality and interest rates and from foreign currency exchange rate changes on non-U.S. Dollar denominated liabilities of our U.S. subsidiaries. Pre-tax underwriting results included foreign currency gains of $18 million in 2021 and losses of $67 million in 2020 and $40 million in 2019. Excluding foreign currency gains/losses, pre-tax underwriting losses from periodic payment annuity contracts were $526 million in 2021, $550 million in 2020 and $509 million in 2019. Pre-tax losses in 2021 were partially offset by the effects of higher mortality and by higher interest rates applicable to settlements under certain contracts. Discounted annuity liabilities were $15.1 billion at December 31, 2021 and had a weighted average discount rate of approximately 3.9%. Variable annuity Variable annuity guarantee reinsurance contracts produced pre-tax earnings of $114 million in 2021, losses of $18 million in 2020 and earnings of $167 million in 2019. The results from these contracts are affected by changes in securities markets, interest rates and foreign currency exchange rates, which can be volatile, and from the periodic amortization of expected profit margins. The comparative increase in underwriting earnings in 2021 was primarily attributable to the net effects of interest rate changes and, to a lesser extent, changes in securities markets. Insurance—Investment Income A summary of net investment income attributable to our insurance operations follows (dollars in millions).

Interest and other investment income declined $470 million (44.4%) in 2021 compared to 2020, which in turn, declined $1.0 billion (49.0%) compared to 2019. These declines were primarily due to lower income from short-term investments and fixed maturity securities. We continue to hold substantial balances of cash, cash equivalents and short-term U.S. Treasury Bills. Short-term interest rates declined over the second half of 2019 and throughout 2020. Low rates prevailed through 2021, which resulted in significantly lower interest income. Nevertheless, we believe that maintaining ample liquidity is paramount and we insist on safety over yield with respect to short-term investments.

Management’s Discussion and Analysis (Continued) Insurance—Investment Income (Continued) Dividend income included $121 million in 2021 and $26 million in 2020 from investments in preferred stock of Berkshire Hathaway Energy. Such amounts are deducted from earnings of the utilities and energy segment. Dividend income may vary from period to period due to changes in the investment portfolio and the frequency and timing of dividends from certain investees. Dividend income increased $365 million (8.1%) in 2020 compared to 2019. The increase was primarily attributable to dividends from the investment in $10 billion liquidation value of 8% cumulative preferred stock of Occidental Petroleum Corporation (“Occidental”) on August 8, 2019, partly offset by lower dividends from common stock investments. Invested assets of our insurance businesses derive from shareholder capital and from net liabilities 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 insurance benefit liabilities, unearned premiums and other liabilities due to policyholders, reduced by insurance premiums and reinsurance receivables, deferred charges assumed under retroactive reinsurance contracts and deferred policy acquisition costs. Float approximated $147 billion at December 31, 2021, $138 billion at December 31, 2020 and $129 billion at December 31, 2019. Our combined insurance operations generated pre-tax underwriting earnings in each of the past three years, and consequently, the average cost of float for each year was negative. A summary of cash and investments held in our insurance businesses as of December 31, 2021 and 2020 follows (in millions). December 31, 2021 2020 Cash, cash equivalents and U.S. Treasury Bills $ 90,688 $ 67,082 Equity securities 334,907 269,498 Fixed maturity securities 16,386 20,317 Other 4,296 6,220 $ 446,277 $ 363,117

Management’s Discussion and Analysis (Continued) Railroad Burlington Northern Santa Fe, LLC (“BNSF”) operates one of the largest railroad systems in North America, with over 32,500 route miles of track in 28 states. BNSF also operates in three Canadian provinces. BNSF classifies its major business groups by type of product shipped including consumer products, industrial products, agricultural products and coal. A summary of BNSF’s earnings follows (dollars in millions).

The following table summarizes BNSF’s railroad freight volumes by business group (cars/units in thousands). Cars/Units Percentage change 2021 2020 2019 2021 vs 2020 2020 vs 2019 Consumer products 5,673 5,266 5,342 7.7% (1.4)% Industrial products 1,709 1,622 1,931 5.4 (16.0) Agricultural products 1,224 1,189 1,146 2.9 3.8 Coal 1,529 1,404 1,802 8.9 (22.1) Total cars/units 10,135 9,481 10,221 6.9 (7.2)

2021 versus 2020 Railroad operating revenues increased 11.6% in 2021 compared to 2020, reflecting higher volumes of 6.9%, as well as a 3.5% increase in average revenue per car/unit resulting from business mix changes and higher fuel surcharge revenue attributable to higher fuel prices. Pre-tax earnings were $7.9 billion in 2021, an increase of 15.7% from 2020. The COVID-19 pandemic caused a significant economic slowdown that adversely affected our volumes in 2020. Revenue changes in 2021 were driven by continued improvements from the 2020 effects of the COVID-19 pandemic, partially offset by the ongoing disruptions in the global supply chain.

Management’s Discussion and Analysis (Continued) Railroad (Continued) Operating revenues from consumer products increased 13.7% in 2021 to $8.3 billion compared to 2020, reflecting increased volumes of 7.7% and higher average revenue per car/unit. The volume increase was primarily due to growth in intermodal in both international and domestic shipments driven by increased retail sales, inventory replenishments by retailers and increased e-commerce activity. Operating revenues from industrial products were $5.3 billion in 2021, an increase of 5.0% from 2020. Volumes increased 5.4% while average revenue per car/unit was nearly unchanged from 2020. The volume increase was primarily due to improvement in the U.S. industrial economy, driving higher volumes in the construction and building sectors, partially offset by lower petroleum volumes due to unfavorable market conditions in the energy sector. Operating revenues from agricultural products increased 5.8% to $5.1 billion in 2021 compared to 2020. The revenue change reflected a volume increase of 2.9% due to higher domestic grain shipments and higher volumes of ethanol and related commodities, as well as higher revenue per car/unit. Operating revenues from coal increased 21.5% to $3.2 billion in 2021 compared to 2020 attributable to higher volumes of 8.9% in 2021, as well as higher average revenue per car/unit. The volume increase in 2021 was attributable to increased electricity generation, higher natural gas prices and improved export demand. Railroad operating expenses were $13.7 billion in 2021, an increase of $1.3 billion (10.2%) compared to 2020. The ratio of railroad operating expenses to railroad operating revenues decreased 0.7 percentage points to 60.9% in 2021 versus 2020. The increase in railroad operating expenses reflected higher volumes and higher average fuel prices, partially offset by the favorable impact of productivity improvements. Compensation and benefits expenses increased $154 million (3.4%) in 2021 compared to 2020, primarily due to increased volumes, wage inflation and health and welfare costs, partially offset by productivity improvements. Fuel expenses increased $977 million (54.6%) compared to 2020, primarily due to higher average fuel prices. Purchased service expenses increased $79 million (4.0%) compared to 2020, primarily due to higher volumes and the effects of insurance recoveries in 2020 related to 2019 flooding, partially offset by improved productivity. Equipment rents, materials and other expenses increased $79 million (4.7%) compared to 2020, due to higher volume-related costs. 2020 versus 2019 Railroad operating revenues declined 11.3% in 2020 versus 2019, reflecting a 7.2% decrease in volume and a 4.5% decrease in average revenue per car/unit. The decrease in revenue per car/unit was attributable to lower fuel surcharge revenue driven by lower fuel prices and business mix changes. The overall volume decrease was primarily due to the COVID-19 pandemic, which severely impacted volumes through the first half of 2020 and caused significant economic disruptions that adversely affected the demand for transportation services. Volumes sequentially improved during the second half of 2020 from earlier periods and recovered overall to pre-pandemic levels by the end of the year. Pre-tax earnings were $6.8 billion in 2020, a decrease of 6.3% from 2019, principally due to the negative impacts of the pandemic on volumes. In addition, pre-tax earnings in 2019 included an operating revenue increase related to the favorable outcome of an arbitration hearing and a retirement plan curtailment gain that is included in other expenses, net in the preceding table. These effects were partially offset by significant improvements in 2020 in service, system velocity and cost performance compared to 2019, along with lower costs related to severe winter weather and flooding on parts of the network, which negatively affected expenses and service levels in 2019. Operating revenues from consumer products of $7.3 billion in 2020 declined 7.6% compared to 2019, primarily due to a 6.3% decrease in average revenue per car/unit along with lower volumes. The volume decrease was primarily due to the impact of the pandemic. Lower international and automotive volumes were offset by higher domestic intermodal volumes. Increased retail sales, inventory replenishments by retailers and e-commerce activity produced recovery of intermodal volumes in the second half of 2020.

Management’s Discussion and Analysis (Continued) Railroad (Continued) Operating revenues from industrial products were $5.0 billion in 2020, a decrease of 17.0% from 2019. The decrease was primarily attributable to the decline in volume and to a lesser extent lower average revenue per car/unit. Volumes decreased primarily due to lower U.S. industrial production driven by the pandemic, including reduced production and demand in the energy sector, which lowered sand and petroleum products volume, and reduced steel demand, which lowered taconite volume. Operating revenues from agricultural products increased 2.9% to $4.8 billion in 2020 compared to 2019. The increase was due to higher volumes, partially offset by slightly lower average revenue per car/unit. The volume increase was primarily due to higher grain and meal exports, partially offset by lower ethanol and sweeteners shipments. Operating revenues from coal decreased 28.5% to $2.7 billion in 2020 compared to 2019. This decrease was primarily due to lower volumes, as well as lower revenues per car/unit. Volumes decreased primarily due to lower natural gas prices, lower electricity demand driven by the pandemic, utility coal plant retirements and mild temperatures. Railroad operating expenses declined 15.3% to $12.4 billion in 2020 as compared to 2019. The ratio of railroad operating expenses to railroad operating revenues declined 2.9 percentage points to 61.6% in 2020 versus 2019. Railroad operating expenses in 2020 reflected lower volume-related costs, productivity improvements, the effects of cost control initiatives and improved weather conditions compared to 2019. Compensation and benefits expenses decreased $728 million (13.8%) in 2020 compared to 2019, primarily due to lower employee counts associated with lower volume and improved workforce productivity. Fuel expenses decreased $1.2 billion (39.2%) compared to 2019, primarily due to lower average fuel prices, lower volumes and improved fuel efficiency. Purchased services expense declined $95 million (4.6%) compared to 2019. The decrease was primarily due to lower volume, improved productivity and higher insurance recoveries in 2020 related to network flooding in 2019. Equipment rents, materials and other expense decreased $344 million (17.0%) compared to 2019, primarily due to lower volume-related costs, the effects of cost controls and lower personal injury and derailment expenses.

The discussion of BHE’s operating results that follows is based on after-tax earnings, reflecting how the energy businesses are managed and evaluated. A summary of net earnings attributable to BHE follows (dollars in millions). Percentage change 2021 2020 2019 2021 vs 2020 2020 vs 2019 PacifiCorp $ 889 $ 741 $ 773 20.0% (4.1)% MidAmerican Energy Company 883 818 781 7.9 4.7 NV Energy 439 410 365 7.1 12.3 Northern Powergrid 247 201 256 22.9 (21.5) Natural gas pipelines 774 528 422 46.6 25.1 Other energy businesses 680 697 608 (2.4) 14.6 Real estate brokerage 387 375 160 3.2 134.4 Corporate interest and other (337) (352) (239) (4.3) 47.3 $ 3,962 $ 3,418 $ 3,126 15.9 9.3 2021 versus 2020 PacifiCorp operates a regulated electric utility in portions of several Western states, including Utah, Oregon and Wyoming. After-tax earnings increased $148 million in 2021 compared to 2020. The increase reflected higher utility margin (operating revenue less cost of sales) and increased income tax benefits from the impacts of ratemaking as well as higher production tax credits recognized on new wind-powered generating facilities placed in-service. The earnings increase was partially offset by lower allowances for equity and borrowed funds used during construction and higher operating expenses. Operating expenses in 2021 reflected increased depreciation expense from the impacts of a deprecation study effective January 1, 2021, and incremental costs associated with wind-powered generating facilities placed in-service, offset by lower costs associated with wildfires and a settlement agreement.

K-44

Management’s Discussion and Analysis (Continued) Utilities and Energy (Continued) PacifiCorp utility margin was $3.5 billion in 2021, an increase of $145 million compared to 2020. The increase reflected higher retail revenue from increases in customer volumes and higher wholesale and other revenue, partially offset by higher thermal generation and purchased power costs. Retail customer volumes increased 3.1% in 2021 as compared to 2020, primarily due to higher customer usage, an increase in the average number of customers and the favorable impacts of weather. MEC operates a regulated electric and natural gas utility primarily in Iowa and Illinois. After-tax earnings increased $65 million in 2021 compared to 2020. The increase reflected higher electric utility margin and increased income tax benefits, partly offset by higher operating expenses. The increase in operating expenses included incremental costs associated with wind-powered generating facilities placed in-service and higher natural gas distribution costs, partially offset by lower storm restoration costs. The income tax benefit increases were mainly due to higher production tax credits recognized on new wind-powered generating facilities placed in-service, partially offset by the impacts of ratemaking. MEC electric utility margin increased $190 million to $2.0 billion in 2021 compared to 2020. The electric utility margin increase was attributable to higher operating revenue from increases in retail and wholesale customer volumes, as well as favorable wholesale prices, partially offset by higher thermal generation and purchased power costs. Electric retail customer volumes increased 5.8% in 2021 as compared to 2020, primarily due to increased usage by certain industrial customers and the favorable impacts of weather. NV Energy operates regulated electric and natural gas utilities in Nevada. After-tax earnings increased $29 million in 2021 compared to 2020. The increase reflected lower operating expenses, lower net interest and finance expense and lower income tax expense from the impacts of ratemaking, partially offset by lower electric utility margin. The decreases in operating expenses were mainly due to lower earnings sharing, partially offset by higher depreciation expense from additional assets placed in-service. NV Energy’s electric utility margin decreased $97 million to $1.6 billion in 2021 compared to 2020. The decrease was primarily due to revenue reductions from lower base tariff general rates in 2021 and a favorable regulatory decision in 2020, partially offset by a 3.3% increase in electric retail customer volumes. The increase in electric retail customer volumes was primarily due to an increase in the average number of customers, higher customer usage and the favorable impacts of weather. Northern Powergrid’s after-tax earnings increased $46 million in 2021 compared to 2020. The increase reflected higher tariff rates and units distributed, lower write-offs of gas exploration costs, lower pension expense and favorable foreign currency exchange rate movements in 2021, partially offset by the impact of increases in the United Kingdom corporate income tax rate. Earnings in 2021 included deferred income tax expense of $109 million related to the enactment in June 2021 of an increase in the income tax rate from 19% to 25%, effective April 1, 2023. Earnings in 2020 included deferred income tax expense of $35 million related to the enactment in July 2020 of an increase in the income tax rate from 17% to 19%, effective April 1, 2020. Natural gas pipelines’ after-tax earnings increased $246 million in 2021 compared to 2020. Earnings in 2021 included BHE GT&S for the full year compared to two months in 2020. The incremental earnings in 2021 from BHE GT&S were $211 million. In addition, earnings in 2021 reflected the effects of higher margins on natural gas sales and higher transportation revenue at Northern Natural Gas due to increased demand from the February 2021 winter storms, partially offset by lower transportation revenue primarily due to lower volumes for the remainder of the year. Other energy businesses’ after-tax earnings in 2021 decreased $17 million compared to 2020. The decrease was mainly due to a decline in wind tax equity investment earnings of $56 million, which included increased losses from pre-existing tax equity investments of $165 million, largely attributable to the February 2021 winter storms, partially offset by increased income tax benefits from projects reaching commercial operation over the past twelve months. Earnings in 2021 from other energy projects increased due to higher operating revenue from owned renewable energy projects and a transmission investment, as well as favorable foreign currency exchange rate movements in 2021. Real estate brokerage after-tax earnings increased $12 million in 2021 compared to 2020. The increase was due to a comparative increase in closed brokerage transaction volumes in 2021, partially offset by lower funded mortgage volume due to a decrease in refinance activity. Corporate interest and other after-tax earnings increased $15 million in 2021 compared to 2020. The increase was primarily due to favorable comparative state income tax benefits and higher earnings from non-regulated energy services, offset by higher operating expenses and higher interest expense from corporate debt issued in 2020.

K-45

Management’s Discussion and Analysis (Continued) Utilities and Energy (Continued) 2020 versus 2019 PacifiCorp after-tax earnings decreased $32 million in 2020 compared to 2019. The decrease reflected higher operating expenses and net interest expense, partially offset by increased production tax credit benefits driven by repowered wind projects placed in-service, higher utility margin and higher other income. The increase in operating expenses was largely due to costs associated with wildfires, a settlement agreement and pension benefits. PacifiCorp utility margin was $3.3 billion in 2020, an increase of $47 million compared to 2019. The increase reflected higher operating revenue from an increase in average retail prices and lower generation and purchased power costs, partially offset by lower operating revenue from a decline in retail customer volumes. The decline in retail customer volumes was due to the impacts of the pandemic, partly offset by an increase in the average number of customers and the favorable impacts of weather. MEC after-tax earnings increased $37 million in 2020 compared to 2019. The increase reflected increased income tax benefits, primarily from production tax credits, driven by repowered and new wind projects placed in-service, and the effects of ratemaking. These effects were partially offset by higher depreciation expense from additional assets placed in-service, higher net interest expense, lower other income and lower electric and natural gas utility margins. MEC electric utility margin decreased $10 million to $1.8 billion in 2020 compared to 2019. The electric utility margin decrease was attributable to lower operating revenue from unfavorable wholesale prices and price impacts from changes in retail sales mix. These effects were mostly offset by lower generation and purchased power costs and higher operating revenue from a 1.2% increase in retail customer volumes. The increase in electric retail customer volumes was primarily due to increased usage by certain industrial customers, partially offset by the impacts of the pandemic. Natural gas utility margin decreased $9 million in 2020 compared to 2019, due to the unfavorable impacts of weather. NV Energy after-tax earnings increased $45 million in 2020 compared to 2019. The increase reflected higher electric utility margin and lower income tax expense from the favorable impacts of ratemaking, partially offset by higher operating expenses. The increase in operating expenses was mainly due to higher earnings sharing accruals for customers at Nevada Power Company and higher depreciation expense from additional assets placed in-service. NV Energy electric utility margin increased $100 million to $1.7 billion in 2020 compared to 2019. The increase was primarily due to higher operating revenue from a 1.5% increase in electric retail customer volumes, including distribution- only service customers and price impacts from changes in retail sales mix. The increase in electric retail customer volumes was primarily due to the favorable impacts of weather, partially offset by the impacts of the pandemic. Northern Powergrid after-tax earnings decreased $55 million in 2020 compared to 2019. The earnings decrease reflected write-offs of gas exploration costs and higher income tax expense, in large part from a change in the United Kingdom corporate income tax rate, partially offset by lower pension costs and interest expense. Natural gas pipelines after-tax earnings increased $106 million in 2020 compared to 2019. The increase was primarily due to $73 million of earnings from BHE GT&S, the favorable impact of a rate case settlement at Northern Natural Gas and higher transportation volume and rates, partially offset by higher depreciation, operating expenses and interest expenses. Other energy business after-tax earnings in 2020 increased $89 million compared to 2019. The increase was primarily due to increased income tax benefits from renewable wind tax equity investments, largely from projects reaching commercial operation, partially offset by lower operating revenue and higher operating expenses from geothermal and natural gas units. Real estate brokerage after-tax earnings increased $215 million in 2020 compared to 2019. The increase reflected higher earnings from mortgage and brokerage services. The increase in earnings from mortgage services was attributable to higher refinance activity from the favorable interest rate environment and the earnings increase from brokerage services was due to an increase of 13.1% in closed transaction dollar volume. Corporate interest and other after-tax earnings decreased $113 million in 2020 compared to 2019. The decline was primarily due to higher interest expense and lower state income tax benefits.

Management’s Discussion and Analysis (Continued) Manufacturing, Service and Retailing (Continued) Industrial 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 tank container and mobile crane industries. The industrial products group also includes equipment and systems for the livestock and agricultural industries (CTB International) and a variety of industrial products for diverse markets (Scott Fetzer and LiquidPower Specialty Products). 2021 versus 2020 Revenues of the industrial products group in 2021 increased $2.5 billion (9.8%) from 2020. Pre-tax earnings increased $714 million (19.0%) compared to 2020 and pre-tax earnings as a percentage of revenues in 2021 was 15.9%, an increase of 1.3 percentage points compared 2020. PCC’s revenues were $6.5 billion in 2021, a decrease of $853 million (11.6%) compared to 2020. Historically, PCC has derived significant revenues and earnings from aerospace products. The COVID-19 pandemic contributed to material declines in commercial air travel and original equipment manufacturing (“OEM”) aircraft production in 2021 and 2020. While commercial air travel increased in both the U.S. and international markets in 2021 versus 2020, demand remains well below pre-pandemic levels, especially for international routes. Long-term industry forecasts continue to show growth and strong demand for travel, however, the recovery has been uneven between domestic and international markets. Air traffic recovery will continue to be impacted by the pandemic, though likely more on a seasonal or localized basis as the pandemic shifts to an endemic phase. Near term recovery in build rates will lag recovery in air travel due to the significant finished goods inventory following quality issues with the Boeing 737 and Boeing 787 planes and industry supply chain issues. PCC’s pre-tax earnings in 2021 were $1.2 billion, an increase of 78.8% compared to 2020. The increase reflects the actions taken by management to resize, restructure and improve operations and to prepare for more normalized demand for PCC’s products, as well as from a decline in restructuring costs. We do not expect significant increases in PCC’s aerospace revenues or earnings to occur in the near term, primarily due to the relatively low aircraft build rates related to Boeing’s significant inventory levels and the ongoing impact of the COVID-19 pandemic on commercial air travel. Lubrizol’s revenues were $6.5 billion in 2021, an increase of 8.6% compared to 2020. The increase reflects higher average selling prices, driven by significant increases in materials and other manufacturing costs, as well as slightly higher volumes. Sales volumes in the Additives product lines were negatively affected by severe winter storms in February 2021, which caused the temporary shut-down of several U.S. facilities, as well as other temporary production shut-downs in the second half of 2021. Lubrizol’s pre-tax earnings in 2021 decreased 50.8% compared to 2020. Earnings in 2021 included significant losses related to a fire in June 2021 at a facility of Chemtool Incorporated, a Lubrizol subsidiary, located in Rockton, Illinois and impairment charges in the second half of 2021 related to an underperforming business in the Advanced Materials product lines. These losses and charges aggregated $257 million in 2021. Earnings in 2021 were also negatively impacted by the effects of accelerating raw material costs and the previously mentioned temporary shut-down of Additives production facilities, which resulted in lost sales and incremental manufacturing costs. Marmon’s revenues were $9.8 billion in 2021, an increase of $2.1 billion (27.9%) compared to 2020. Revenues in 2021 from the Electrical, Metal Services and Plumbing & Refrigeration groups increased 54% over 2020, accounting for over half of the aggregate increase in Marmon’s revenues. These increases were attributable to higher volumes and prices, including the impact of significantly higher average copper and metal prices. Revenues of most of Marmon’s other groups, particularly those serving the construction, automotive, heavy-duty truck and restaurant markets, also increased in 2021, reflecting higher volumes and favorable foreign currency translation effects. These increases were partially offset by the impact of divestitures and business closures in the Water Technologies and Retail Solutions groups and lower lease revenues in the Rail & Leasing group, reflecting fewer railcars on lease and changes in lease mix. Marmon’s pre-tax earnings in 2021 increased 40.3% compared to 2020. The increase was primarily due to earnings increases in the Electrical, Metal Services and Plumbing & Refrigeration groups due to higher volumes and average margins. Earnings of several other business groups also increased attributable to higher sales volumes, sales mix changes and lower restructuring charges, which were partially offset by lower earnings from the Rail & Leasing and Water Technologies groups.

Management’s Discussion and Analysis (Continued) Manufacturing, Service and Retailing (Continued) Industrial products (Continued) IMC’s revenues increased 19.5% in 2021 compared to 2020, reflecting improving business conditions in most geographic regions and favorable foreign currency translation effects. IMC’s pre-tax earnings increased 47.7% in 2021 versus 2020, primarily attributable to higher customer demand, improved manufacturing efficiencies, operating cost management saving initiatives and favorable foreign currency translation effects. 2020 versus 2019 Revenues of the industrial products group in 2020 declined $4.9 billion (16.1%) from 2019, while pre-tax earnings declined $1.9 billion (33.4%). Pre-tax earnings as a percentage of revenues for the group was 14.6% in 2020 compared to 18.4% in 2019. PCC’s revenues were $7.3 billion in 2020, a decrease of $3.0 billion (28.9%) compared to 2019. The COVID-19 pandemic contributed to material declines in commercial air travel and aircraft production. Airlines responded to the pandemic by delaying delivery of aircraft orders or, in some cases, cancelling aircraft orders, resulting in significant reductions in build rates by aircraft manufacturers and significant inventory reduction initiatives by PCC’s customers. Further, Boeing’s 737 MAX aircraft production issues contributed to the declines in aerospace product sales across the industry in 2020. These factors resulted in significant declines in demand for PCC’s aerospace products in 2020. PCC’s sales of products for power markets increased 2.2% in 2020, primarily driven by increases in industrial gas turbine products, offset by reductions in oil and gas products. PCC’s pre-tax earnings were $650 million in 2020, a decrease of 64.5% compared to 2019, which reflected the decline in aerospace product sales as well as increased manufacturing inefficiencies attributable to lower volumes. In response to the effects of the pandemic, PCC took aggressive restructuring actions to resize operations in response to reduced expected volumes in aerospace markets. PCC’s worldwide workforce was reduced by about 40% from the end of 2019. PCC recorded restructuring, inventory and fixed asset charges of approximately $295 million in 2020. Earnings as a percentage of revenues were negatively impacted in 2020 due to inefficiencies associated with aligning operations to reduced aircraft build rates. Lubrizol’s revenues were $5.95 billion in 2020, a decrease of 8.0% compared to 2019. The decline was primarily attributable to lower volumes from economic effects of the pandemic and a fire at an Additives manufacturing, blending and storage facility in Rouen, France at the end of the third quarter of 2019, which resulted in the temporary suspension of operations. Revenues in 2020 also reflected lower selling prices, partly offset by favorable changes in sales mix. Lubrizol’s consolidated volume for the year declined 9% in 2020 compared to 2019 due to declines in the Additives and Engineered Materials product lines, partly offset by higher volumes in Life Science products. Lubrizol’s pre-tax earnings in 2020 were approximately $1.0 billion, essentially unchanged compared to 2019. The effects of lower sales volumes, including the effects from the Rouen fire, and lower average selling prices were offset by lower average raw material costs, lower operating expenses and insurance recoveries in 2020 associated with the Rouen fire. Marmon’s revenues were $7.6 billion in 2020, a decrease of $681 million (8.2%) compared to 2019. Excluding the effects of business acquisitions, revenues decreased in essentially all groups, primarily attributable to lower demand from the effects of the pandemic. The largest effects were experienced in the Transportation Products and Foodservice Technologies groups. Additionally, revenues decreased due to lower metal prices in the Metal Services group and the effect of business divestitures in 2019. Declines in oil prices in 2020 also adversely affected demand and revenues in the Rail & Leasing and Crane Services groups. Marmon acquired the Colson Medical companies on October 31, 2019, which represents Marmon’s Medical group. Marmon’s pre-tax earnings in 2020 decreased $312 million (24.3%) compared to 2019. The decrease reflected the declines in revenues and increased restructuring charges. Restructuring initiatives were initiated in response to the lower product demand, particularly in the sectors most impacted by the pandemic.

Management’s Discussion and Analysis (Continued) Manufacturing, Service and Retailing (Continued) Industrial products (Continued) IMC’s revenues declined 13.2% in 2020 compared to 2019, reflecting negative economic effects from the pandemic on demand for cutting tools in most geographic regions, partly offset by the effects of business acquisitions. IMC’s pre-tax earnings declined 26.6% in 2020 versus 2019, attributable to declines in sales and margins due to lower volumes and to changes in sales mix. 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 and engineering products and systems (MiTek). 2021 versus 2020 Revenues of the building products group increased $3.7 billion (17.6%) in 2021 and pre-tax earnings increased $532 million (18.6%) compared to 2020. Pre-tax earnings as percentages of revenues were 13.6% in 2021 and 13.5% in 2020. During 2021, our businesses experienced strong customer demand and higher sales volumes. We also experienced various forms of supply chain disruptions, which affected the general economy, and contributed to considerable raw material and logistics cost inflation and supply constraints. Clayton Homes’ revenues were approximately $10.5 billion in 2021, an increase of $1.9 billion (22.2%) over 2020. Revenues from home sales increased $1.8 billion (26.5%) in 2021 to approximately $8.3 billion, reflecting increased revenue per home sold, changes in sales mix and a net increase in new units sold. Unit sales of site-built homes increased 15.8% in 2021, while factory-built manufactured home unit sales increased 1.5%. Site-built home unit sales were constrained by longer construction periods arising from supply chain constraints and labor shortages. Financial services revenues, which include mortgage origination and services, insurance and interest income from lending activities, increased 7.8% in 2021 compared to 2020. Loan balances, net of allowances for credit losses, were approximately $18.8 billion as of December 31, 2021, an increase of approximately $1.7 billion compared to December 31, 2020. Pre-tax earnings of Clayton Homes were approximately $1.7 billion in 2021, an increase of $440 million (35.3%) compared to 2020. Earnings in 2021 reflected higher earnings from home sales, mortgage originations, net interest income and lower provisions for expected credit losses, partially offset by the impact of rising manufacturing and supply chain costs. The provision for expected credit losses in 2020 was unusually high and included provisions for the expected impact of the COVID-19 pandemic. The comparative decline in the provision for expected credit losses was due to fewer actual and anticipated loan foreclosures. Aggregate revenues of our other building products businesses were approximately $14.5 billion in 2021, an increase of 14.4% versus 2020. The increase was primarily due to higher average selling prices driven by significantly higher input and supply chain costs, as well as higher unit volumes for paint and coatings, flooring, insulation, roofing and other engineered products. Pre-tax earnings of the other building products businesses were approximately $1.7 billion in 2021, an increase of 5.7% over 2020. Pre-tax earnings as a percentage of revenues was 11.8% in 2021, a 1.0 percentage point decrease compared to 2020. While customer demand in 2021 was generally strong, reduced availability of materials and other product inputs from supply chain disruptions negatively affected sales and operating results. In addition, higher costs for raw materials and freight and higher restructuring and impairment charges contributed to the reduction in our pre-tax margin rates. 2020 versus 2019 Revenues of the building products group increased $917 million (4.5%) in 2020 compared to 2019 and pre-tax earnings increased $222 million (8.4%) over 2019. Pre-tax earnings as percentages of revenues were 13.5% in 2020 and 13.0% in 2019.

Management’s Discussion and Analysis (Continued) Manufacturing, Service and Retailing (Continued) Building products (Continued) Clayton Homes’ revenues were approximately $8.6 billion in 2020, an increase of $1.3 billion (17.1%) over 2019. The increase was primarily due to increases in home sales of $1.0 billion (18.4%), driven by increases in units sold and revenue per home sold and by changes in sales mix. Unit sales of site-built homes increased 28.6% in 2020 over 2019, while revenue per home increased slightly. Manufactured home unit sales increased 2.8% in 2020. Financial services revenues increased 13.7% in 2020 compared to 2019, attributable to increased loan originations and average outstanding loan balances. Loan balances, net of allowances for credit losses, were approximately $17.1 billion at December 31, 2020 compared to $15.9 billion as of December 31, 2019. Pre-tax earnings of Clayton Homes were approximately $1.25 billion in 2020, an increase of $152 million (13.9%) compared to 2019. The earnings increase reflected higher earnings from home sales, partly offset by higher materials costs, which lowered manufactured housing gross margin rates. Earnings in 2020 also benefitted from increased interest income, lower interest expense and higher earnings from mortgage services, partly offset by increased provisions for credit and insurance losses. Aggregate revenues of our other building products businesses were approximately $12.6 billion in 2020, a decrease of 2.6% versus 2019. The revenue decrease reflected lower flooring volumes, in part attributable to the negative effects of the COVID-19 pandemic, partially offset by increased paint and coatings volumes, including volumes from a new agreement with Ace Hardware Stores, and increased volumes in residential markets. Pre-tax earnings of the other building products businesses were approximately $1.6 billion in 2020, an increase of 4.6% over 2019. The earnings increase reflected the effects of lower average input costs, operating cost containment efforts and lower facilities closure costs. 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) and jewelry products (Richline). 2021 versus 2020 Consumer products revenues increased $3.4 billion (28.0%) in 2021 versus 2020. Revenues from Forest River increased 40.2% in 2021 compared to 2020, driven by a 27.6% increase in recreational vehicle unit sales and higher average selling prices, primarily due to significant increases in manufacturing costs. Revenues of several of our other consumer products businesses were significantly higher in 2021 as compared to 2020. The initial impacts of the pandemic in the first half of 2020 from temporary retail store closures and reduced demand had a severe impact on most of these businesses. Apparel and footwear revenues increased 25.3% in 2021 compared to 2020, reflecting significant increases in unit sales, partly attributable to inventory restocking by certain customers, and from increased consumer demand. Revenues from Richline increased 39.9%, while revenues from Duracell increased 2.4%. Consumer products pre-tax earnings increased $585 million (41.9%) in 2021 compared to 2020 and as a percentage of revenues in 2021 increased 1.2 percentage points to 12.7%. The increase reflected significant earnings increases at many of our businesses, driven by Forest River, the apparel and footwear businesses, Richline and Larson-Juhl. However, our consumer products businesses, particularly the apparel and footwear businesses, also experienced significant cost increases and supply chain disruptions, causing pre-tax margins in the second half of 2021 to be 1.1 percentage points lower than in the first half of the year. 2020 versus 2019 Consumer products revenues increased $359 million (3.0%) in 2020 versus 2019, while pre-tax earnings increased $146 million (11.7%). Pre-tax earnings as a percentage of revenues in 2020 increased 0.9 percentage points to 11.5%.

Management’s Discussion and Analysis (Continued) Manufacturing, Service and Retailing (Continued) Consumer products (Continued) The comparative increase in revenues reflected increases from Forest River and Duracell, partially offset by lower apparel and footwear revenues. Forest River revenues increased 11.7% in 2020 compared to 2019, primarily attributable to a significant increase in recreational vehicle unit sales over the last half of the year and changes in sales mix. Unit sales in the second half of 2020 increased 31% over the second half of 2019. Revenues from Duracell increased 10.0% in 2020 compared to 2019, reflecting the effects of changes in sales mix and increased volume. Apparel and footwear revenues declined 6.1% in 2020 compared to 2019. Apparel and footwear sales volumes in the first half of 2020, particularly in the second quarter, reflected the negative effects of the pandemic, which included retail store closures, reduced or cancelled orders and pandemic-related disruptions at certain manufacturing facilities. Sales recovered somewhat in the second half of 2020, attributable to higher consumer demand and inventory restocking by retailers. Brooks Sports revenues were higher, partly attributable to the effect of the reduced sales in 2019 that were caused by shipping delays at a new distribution facility. Pre-tax earnings were $1.4 billion in 2020, an increase of $146 million (11.7%) compared to 2019. The increase was primarily attributable to Forest River and Duracell, partially offset by lower earnings from apparel and footwear. The overall increase reflected the effects of sales volumes changes and ongoing expense management efforts. Service and retailing A summary of revenues and pre-tax earnings of our service and retailing businesses follows (dollars in millions). Percentage change 2021 2020 2019 2021 vs 2020 2020 vs 2019 Revenues Service $ 15,872 $ 12,346 $ 13,496 28.6% (8.5)% Retailing 18,960 15,832 15,991 19.8 (1.0) McLane 49,450 46,840 50,458 5.6 (7.2) $ 84,282 $ 75,018 $ 79,945 Pre-tax earnings Service $ 2,672 $ 1,600 $ 1,681 67.0% (4.8)% Retailing 1,809 1,028 874 76.0 17.6 McLane 230 251 288 (8.4) (12.8) $ 4,711 $ 2,879 $ 2,843 Pre-tax earnings as a percentage of revenues Service 16.8% 13.0% 12.5% Retailing 9.5% 6.5% 5.5% McLane 0.5% 0.5% 0.6% Service Our 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 and services to operators of aircraft, and TTI, a distributor of electronics components. Our other service businesses franchise and service 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), distribute electronic news, multimedia and regulatory filings (Business Wire) and operate a television station in Miami, Florida (WPLG).

Management’s Discussion and Analysis (Continued) Manufacturing, Service and Retailing (Continued) Service (Continued) 2021 versus 2020 Service group revenues increased $3.5 billion (28.6%) in 2021 compared to 2020, primarily attributable to higher revenues from TTI and the aviation services businesses. Revenues from TTI increased 37.4% in 2021 versus 2020, primarily attributable to significantly higher volumes across all significant markets and product categories, and to a lesser extent, higher average prices and changes in sales mix. Customer demand accelerated throughout 2021, as customers attempted to maintain adequate inventories in response to high demand for components in end products and effects of supply chain disruptions. Revenues from aviation services increased 27.5% in 2021 over low 2020 levels, primarily due to higher training hours (24%) and customer flight hours (70%). Pre-tax earnings of our service business group increased $1.1 billion (67.0%) to $2.7 billion. Pre-tax earnings of the group as a percentage of revenues were 16.8% in 2021, an increase of 3.8 percentage points compared to 2020. Earnings at nearly all service businesses increased in 2021 compared to 2020, with the largest increases from TTI, the aviation services businesses and the XTRA leasing business. TTI’s earnings increase was primarily attributable to the increases in sales volumes, as well as from improved operating cost leverage and changes in sales mix. The increase in earnings from aviation services was attributable to the favorable effects of higher volume, changes in business mix, increased operating efficiencies, lower impairment charges and the effects of past restructuring efforts, partly offset by higher subcontractor costs attributable to the significant increase in flight demand. 2020 versus 2019 Service group revenues declined $1.15 billion (8.5%) in 2020 compared to 2019 and pre-tax earnings decreased $81 million (4.8%). Pre-tax earnings of the group as a percentage of revenues were 13.0% in 2020, an increase of 0.5 percentage points compared to 2019. The aggregate revenues of NetJets and FlightSafety in 2020 declined $816 million (13.5%) compared to 2019, reflecting lower demand for air travel and aviation services attributable to the COVID-19 pandemic. NetJets experienced a decline in customer flight hours of 27% and FlightSafety’s commercial and corporate simulator training hours declined 30% from 2019. The comparative service group revenue decline also reflected the disposition of the newspaper operations in March of 2020 and lower revenues from CORT, which was driven by lower demand attributable to the pandemic. These declines were partially offset by revenue increases from TTI and WPLG. The decline in earnings reflected lower earnings from NetJets, TTI and CORT and the divestiture of the newspaper operations, partly offset by higher earnings from XTRA, Business Wire, WPLG and FlightSafety. TTI’s earnings decline reflected lower average gross margin rates, attributable to product mix changes and sales price pressures deriving from ample inventory availability. The decline at NetJets was primarily attributable to increased asset impairment charges and restructuring costs, partly offset by lower general and administrative expenses and a slight net increase in margins. The decline at CORT was driven by lower revenues, partly offset by the effects of cost control initiatives. The increase at FlightSafety was attributable to the effects of contract losses of approximately $165 million recorded in 2019 with respect to an existing government contract and cost control efforts in 2020, which more than offset significantly lower earnings from commercial and corporate training services. Retailing Our largest retailing business is Berkshire Hathaway Automotive, Inc. (“BHA”), representing 62% of our combined retailing revenue in 2021. BHA consists of over 80 auto dealerships that sell new and pre-owned automobiles and offer repair services and related products. BHA also operates two insurance businesses, two auto auctions and an automotive fluid maintenance products distributor. Our retailing businesses also include four home furnishings retailing businesses (Nebraska Furniture Mart, R.C. Willey, Star Furniture and Jordan’s), which sell furniture, appliances, flooring and electronics. The home furnishings group represented 21% of the combined retailing revenues in 2021. Other retailing businesses include three jewelry retailing businesses (Borsheims, Helzberg and Ben Bridge), See’s Candies (confectionary products), Pampered Chef (high quality kitchen tools), Oriental Trading Company (party supplies, school supplies and toys and novelties) and Detlev Louis Motorrad (“Louis”), a retailer of motorcycle accessories based in Germany.

Management’s Discussion and Analysis (Continued) Manufacturing, Service and Retailing (Continued) Retailing (Continued) 2021 versus 2020 Retailing group revenues in 2021 increased $3.1 billion (19.8%) compared to 2020. BHA’s revenues increased 19.0% in 2021 compared to 2020, with vehicle sales, service and repair, and finance and service contract revenues each increasing versus 2020. Revenues from vehicle sales in 2021 increased $1.7 billion (20.7%) versus 2020, primarily due to higher average selling prices, as well as a 2.7% increase in units sold. However, new vehicle unit sales in the second half of 2021 declined 18% compared to the second half of 2020, reflecting significant new vehicle supply shortages at OEMs attributable to the global computer chip shortages and other supply chain disruptions. Home furnishings group revenues increased 22.0% in 2021 as compared to 2020, attributable to higher consumer demand and higher average selling prices, driven by higher inventory and freight costs. Pre-tax earnings in 2021 of the retailing group increased $781 million (76.0%) from 2020 and the pre-tax margin rate increased 3.0 percentage points to 9.5%. BHA’s pre-tax earnings increased 47.5% in 2021 compared to 2020, primarily due to increased vehicle sales margins and higher earnings from finance and service contract activities. In addition, earnings in 2021 benefitted from lower floorplan interest expense, attributable to significant declines in inventory levels, and from ongoing operating cost control efforts. Home furnishings group pre-tax earnings increased 67.6% in 2021 versus 2020, reflecting generally higher average gross margin rates and sales mix changes and cost control efforts, partly offset by higher personnel costs. Aggregate pre-tax earnings for the remainder of our retailing group increased $321 million in 2021 compared to 2020. The initial effects of the pandemic in 2020 were severe for most of our other retailers due to the restricted operations at many of those businesses. Results in 2021 also benefitted from relatively strong consumer demand and the effects of restructuring efforts in 2020. 2020 versus 2019 Retailing group revenues in 2020 declined $159 million (1.0%) compared to 2019. The spread of COVID-19 resulted in the temporary closures or restricted operations at several of our retailing businesses and effected consumer spending patterns during 2020. The severity and duration of the effects from the pandemic varied widely at our retail operations. BHA’s revenues decreased 2.9% in 2020 compared to 2019. BHA’s revenues in 2020 reflected decreases in new and pre-owned vehicle sales of 2.6%, as well as lower vehicle service and repair revenues. Home furnishings revenues were essentially unchanged in 2020 compared to 2019. The retailing group experienced lower revenues in the first half of 2020, attributable to restricted store hours, which were substantially offset by increased revenues over the second half of the year. However, supply chain disruptions had a negative effect on obtaining product at certain times, which negatively affected sales levels. The effects of the pandemic contributed to significantly lower sales in 2020 for our jewelry stores, See’s Candies and Oriental Trading Company, which were more than offset by significant revenue increases from Pampered Chef and Louis. Sales volumes generally increased and operating results improved beginning in the latter part of the second quarter as our operations slowly reopened. Retail group pre-tax earnings increased $154 million (17.6%) in 2020 from 2019. BHA’s pre-tax earnings increased 37.7%, primarily due to lower selling, general and administrative expenses, lower floorplan interest expense and higher average gross sales margin rates. Aggregate pre-tax earnings for the remainder of our retailing group increased 1.1% in 2020 compared to 2019, reflecting higher earnings from the home furnishings businesses and from Pampered Chef, which were substantially offset by lower earnings from our other retailing operations. Home furnishings group pre-tax earnings increased $79 million (36%) in 2020 versus 2019, reflecting generally higher average gross margin rates, sales mix changes and fewer sales promotions and lower advertising and other operating expenses. Certain of our other operations, including Pampered Chef and Louis experienced significant earnings increases in 2020, while others, including See’s Candies and Oriental Trading Company, experienced significant declines driven by the negative effects of the pandemic.

Management’s Discussion and Analysis (Continued) Manufacturing, Service and Retailing (Continued) Retailing (Continued) McLane McLane Company, Inc. (“McLane”) operates a wholesale distribution business that provides grocery and non-food consumer 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 about 63% of McLane’s consolidated sales in 2021 with food service 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. 2021 versus 2020 Revenues increased $2.6 billion (5.6%) in 2021 compared to 2020. Revenues from the grocery business increased 1.5% compared to 2020, while revenues from the foodservice and beverage businesses increased 13.1% and 17.8%, respectively. The foodservice business was significantly impacted by pandemic-related restaurant closures in 2020. Pre-tax earnings decreased $21 million (8.4%) in 2021 as compared to 2020. The decrease reflected significant increases in personnel, contract transportation and fuel costs, which more than offset the favorable impact of higher sales and slightly higher gross sales margins. McLane’s grocery and food service operations were significantly affected in 2021 by upstream supply chain constraints, including the effects of labor and truck driver shortages, which contributed to higher inventory costs reflected in a LIFO inventory reserve increase of $130 million, and disruptions in inventory availability. These upstream supply chain effects, together with the truck driver and warehouse personnel shortages that we are experiencing, adversely affected our customer service levels and reduced our operating efficiencies. In response, our hiring and wage and benefits costs increased significantly in 2021. The increase in fuel expense was primarily attributable to significant increases in petroleum prices. We expect the current difficult operating environment to continue through 2022. 2020 versus 2019 Revenues declined $3.6 billion (7.2%) in 2020 compared to 2019. The decline was attributable to COVID-19-related restaurant closures (particularly in the casual dining category) in the foodservice business and lower sales in certain product categories within the grocery business. McLane operates on a 52/53-week fiscal year and 2020 included 52 weeks compared to 53 weeks in 2019. Otherwise, revenues declined 5.2% in the grocery business and 7.7% in the foodservice business in 2020 as compared to 2019. Pre-tax earnings decreased $37 million (12.8%) in 2020 as compared to 2019. The earnings decrease included the effects of increased LIFO inventory reserves of $22 million, credit and inventory losses of $12 million in the foodservice operations and the impact of lower sales. Investment and Derivative Contract Gains/Losses A summary of investment and derivative contract gains/losses follows (dollars in millions). 2021 2020 2019 Investment gains/losses $ 77,576 $ 40,905 $ 71,123 Derivative contract gains/losses 966 (159) 1,484 Gains/losses before income taxes and noncontrolling interests 78,542 40,746 72,607 Income taxes and noncontrolling interests 16,202 9,155 15,162 Net earnings $ 62,340 $ 31,591 $ 57,445 Effective income tax rate 20.4% 21.7% 20.9%

Management’s Discussion and Analysis (Continued) Investment and Derivative Contract Gains/Losses (Continued) Investment gains/losses Unrealized gains and losses arising from changes in market prices of our investments in equity securities are included in our reported earnings, which significantly increases the volatility of our periodic net earnings due to the magnitude of our equity securities portfolio and the inherent volatility of equity securities prices. Pre-tax investment gains/losses included net unrealized gains of approximately $76.4 billion in 2021, $55.0 billion in 2020 and $69.6 billion in 2019 attributable to changes in market prices of equity securities we held at the end of each year. In 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 $1.0 billion in 2021, losses of $14.0 billion in 2020 and gains of $1.6 billion in 2019. 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 $3.6 billion in 2021, $6.2 billion in 2020 and $3.2 billion in 2019. We believe that investment gains/losses, whether realized from sales or unrealized from changes in market prices, are often meaningless in terms of understanding our periodic consolidated earnings or evaluating our periodic economic performance. We continue to believe the investment gains/losses recorded in earnings, including the changes in market prices for equity securities, in any given period has little analytical or predictive value. Derivative contract gains/losses Derivative contract gains/losses include the changes in fair value of our equity index put option contract liabilities, which relate to contracts that were originated prior to March 2008. A vast majority of these contracts have since expired. Contracts comprising 63% of the remaining notional value as of December 31, 2021 will expire in the first quarter of 2022. The periodic changes in the fair values of these liabilities are recorded in earnings and, historically, were significant, primarily due to the volatility of underlying equity markets. As of December 31, 2021, the intrinsic value of our equity index put option contracts was near zero and our recorded liability at fair value was approximately $99 million. Our ultimate payment obligations, if any, under our contracts will be determined as of the contract expiration dates based on the intrinsic value as defined under the contracts. The pre-tax gains and losses in each of the past three years reflected changes in the equity index values and shorter remaining contract durations. Settlement payments to counterparties over the past three years were insignificant. Other A summary of after-tax other earnings/losses follows (in millions). 2021 2020 2019 Equity method earnings $ 881 $ 665 $ 1,023 Acquisition accounting expenses (690) (783) (788) Goodwill and intangible asset impairments — (10,381) (96) Corporate interest expense, before foreign currency effects (305) (334) (280) Foreign currency exchange rate gains (losses) on Berkshire and BHFC non-U.S. Dollar senior notes 955 (764) 58 Other Berkshire corporate 474 279 507 $ 1,315 $ (11,318) $ 424

After-tax equity method earnings include our proportionate share of earnings attributable to our investments in Kraft Heinz, Pilot, Berkadia, Electric Transmission of Texas and Iroquois Gas Transmission Systems. Our after-tax earnings from Kraft Heinz were $317 million in 2021, $170 million in 2020 and $488 million in 2019. Our earnings from Kraft Heinz included our after-tax share of goodwill and other intangible asset impairment charges recorded by Kraft Heinz in each year. Our after-tax share of such charges was $259 million in 2021, $611 million in 2020 and $339 million in 2019.

K-56

Management’s Discussion and Analysis (Continued) Other (Continued) After-tax acquisition accounting expenses include charges arising from the application of the acquisition method in connection with certain of Berkshire’s past business acquisitions. Such charges arise primarily from the amortization or impairment of intangible assets recorded in connection with those business acquisitions. Goodwill and intangible asset impairments in 2020 included after-tax charges of $9.8 billion attributable to impairments of goodwill and certain identifiable intangible assets that were recorded in connection with our acquisition of PCC in 2016. See Other Critical Accounting Policies on page K-62 for additional details. Foreign currency exchange rate gains and losses pertain to Berkshire’s Euro and Japanese Yen denominated debt and BHFC’s Great Britain Pound denominated debt. Changes in foreign currency exchange rates produce unrealized gains and losses from the periodic revaluation of these liabilities into U.S. Dollars. 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. Berkshire corporate items consist primarily of Berkshire parent company investment income and corporate expenses, other intercompany interest income where the interest expense is included in earnings of the operating businesses and unallocated income taxes. Financial Condition Our consolidated balance sheet continues to reflect very significant liquidity and a very strong capital base. Consolidated shareholders’ equity at December 31, 2021 was $506.2 billion, an increase of $63.0 billion since December 31, 2020. Net earnings attributable to Berkshire shareholders was $89.8 billion and included after-tax gains on our investments of approximately $61.6 billion. Over each of the last three years, investment gains and losses from changes in the market prices of our investments in equity securities produced exceptional volatility in our periodic 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 and Chief Executive Officer, and Charlie Munger, Vice 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 Berkshire’s consolidated cash, cash equivalents and U.S. Treasury Bill holdings below $30 billion. Financial strength and redundant liquidity will always be of paramount importance at Berkshire. Berkshire paid $27.1 billion in 2021 to repurchase shares of its Class A and B common stock. At December 31, 2021, our insurance and other businesses held cash, cash equivalents and U.S. Treasury Bills of $143.9 billion, which included $119.6 billion in U.S. Treasury Bills. Investments in equity and fixed maturity securities (excluding our investment in Kraft Heinz) were $367.2 billion. Our fixed maturity securities at December 31, 2021 included approximately $14.4 billion of investments that mature in 2022 and 2023. Our consolidated borrowings at December 31, 2021 were $114.3 billion, of which over 95% were by the Berkshire parent company, BHFC, BNSF and BHE and its subsidiaries. Expected principal and interest payments related to our consolidated borrowings in each of the next five years are (in billions): $10.2 in 2022; $14.6 in 2023; $9.7 in 2024; $9.9 in 2025; and $8.7 in 2026. Berkshire parent company debt outstanding at December 31, 2021 was $21.4 billion, a decrease of $1.3 billion since December 31, 2020, which was primarily due to the effects of foreign currency exchange rate changes on Euro and Japanese Yen denominated debt. In 2021, Berkshire repaid Euro and U.S. Dollar denominated debt aggregating approximately $2.2 billion of maturing senior notes and issued Euro and Yen denominated senior notes aggregating approximately $2.2 billion with maturity dates ranging from 2026 to 2041 and a weighted average interest rate of 0.5%. In January 2022, Berkshire repaid $600 million of maturing senior notes and issued ¥128.5 billion (approximately $1.1 billion) of senior notes with maturity dates ranging from 2027 to 2052 and a weighted average interest rate of 0.5%. Berkshire’s insurance and other subsidiary outstanding borrowings were approximately $17.9 billion at December 31, 2021, which included senior note borrowings of BHFC, a wholly-owned financing subsidiary, of approximately $13.1 billion. BHFC’s borrowings are used to fund a portion of loans originated and acquired by Clayton Homes and equipment held for lease by our railcar leasing business. In 2021, BHFC repaid $750 million of maturing senior notes and issued $750 million of 2.5% senior notes due in 2051. Berkshire guarantees BHFC’s senior notes for the full and timely payment of principal and interest.

Management’s Discussion and Analysis (Continued) Financial Condition (Continued) BNSF’s outstanding debt was $23.2 billion as of December 31, 2021, relatively unchanged from December 31, 2020. During 2021, BNSF repaid $1.54 billion of debt and issued $1.55 billion of debentures with a weighted average interest rate of 3.1% with maturity dates in 2051 and 2052. Outstanding borrowings of BHE and its subsidiaries were $51.8 billion at December 31, 2021, a decrease of $382 million since December 31, 2020. In 2021, BHE and its subsidiaries issued new term debt of approximately $2.2 billion with maturity dates ranging from 2028 to 2052 and repaid term debt of approximately $2.5 billion. Berkshire does not guarantee the repayment of debt issued by BNSF, BHE or any of their subsidiaries. In each of the past three years, our diverse group of businesses generated net operating cash flows of approximately $39 billion. Our consolidated capital expenditures for property, plant and equipment and equipment held for lease were $13.3 billion in 2021, which included capital expenditures by our railroad, utilities and energy businesses (BNSF and BHE) of $9.5 billion. BNSF and BHE maintain very large investments in capital assets (property, plant and equipment) and will regularly make significant capital expenditures in the normal course of business. We forecast capital expenditures of these two operations will approximate $11.1 billion in 2022. Contractual Obligations We are party to other contracts associated with ongoing business activities, which will result in cash payments to counterparties in future periods. Certain obligations are included in our Consolidated Balance Sheets, such as operating lease liabilities and shared aircraft repurchase liabilities of NetJets. Estimated payments of these liabilities in each of the next five years are (in billions): $1.6 in 2022; $1.5 in 2023; $1.4 in 2024; $1.2 in 2025; and $1.2 in 2026. We are also obligated to pay claims arising from property and casualty insurance companies. Such liabilities, including amounts from retroactive reinsurance, were approximately $125 billion at December 31, 2021. We currently forecast claim payments in 2022 of approximately $29 billion with respect to claims occurring prior to 2022. Additionally, we estimate net payments of approximately $3 billion in 2022 for life, health and annuity benefits under contracts. However, the timing and amount of the payments under insurance and reinsurance contracts are contingent upon the outcome of future events. Actual payments will likely vary, perhaps materially, from the forecasted payments, as well as from the liabilities currently recorded in our Consolidated Balance Sheet. We anticipate that these 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 are delivered or services are provided. As of December 31, 2021, the largest categories of our long-term contractual obligations primarily related to fuel, capacity, transmission and maintenance contracts and capital expenditure commitments of BHE and BNSF and aircraft purchase commitments of NetJets. We estimate future payments associated with these contracts over the next five years of approximately $19 billion, including $8 billion in 2022. We also have an agreement to acquire an additional 41.4% of Pilot in 2023 and agreements to acquire certain non-controlling interests of consolidated subsidiaries. Reference is made to Note 26 to the Consolidated Financial Statements for additional information regarding these commitments. Critical Accounting Policies 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 our principal accounting policies that required the application of significant judgments as of December 31, 2021 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 from insureds and ceding companies and the final determination of the loss amount through the loss adjustment and settlement process. We use a variety of techniques in establishing claim liabilities, which may require significant judgments and assumptions. As of the balance sheet date, recorded claim liabilities include estimates for reported claims and for claims not yet reported. The period between the loss occurrence date and loss settlement date is the “claim-tail.” Property claims usually have relatively short claim-tails, absent litigation. Casualty claims usually have longer claim-tails, occasionally extending for 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.

Management’s Discussion and Analysis (Continued) Property and casualty losses (Continued) Our consolidated claim liabilities, including liabilities from retroactive reinsurance contracts, as of December 31, 2021 were approximately $125 billion, of which 80% 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 these businesses follows. GEICO GEICO predominantly writes private passenger auto insurance. As of December 31, 2021, GEICO’s gross unpaid losses were $23.9 billion and claim liabilities, net of reinsurance recoverable, were $22.7 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 automobile 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, 2021, case development liabilities averaged approximately 34% of the case reserves. We select case development factors through analysis of the overall adequacy of historical case liabilities. Incurred-but-not-reported (“IBNR”) claim liabilities are based on projections of the ultimate number of claims expected (reported and unreported) for each significant coverage. We use historical claim count data to develop age-to-age projections of the ultimate counts by quarterly accident period, from which we deduct reported claims to produce the number of unreported claims. We estimate the average costs per unreported claim and apply such estimates to the unreported claim counts, producing an IBNR liability estimate. We may record additional IBNR estimates when actuarial techniques are difficult to apply. 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 a given period and projects the ultimate cost. Our claim liability estimates recorded at the end of 2020 were reduced by $1.8 billion during 2021, which produced a corresponding increase to pre-tax earnings. The assumptions used to estimate liabilities at December 31, 2021 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, 2021. We estimate that a one percentage point increase or decrease in BI severities would produce a $290 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 the same direction. Berkshire Hathaway Reinsurance Group BHRG’s liabilities for unpaid losses and loss adjustment expenses derive primarily from reinsurance contracts issued through NICO and General Re.

Management’s Discussion and Analysis (Continued) Property and casualty losses (Continued) Berkshire Hathaway Reinsurance Group (Continued) Gross unpaid losses and loss adjustment expenses consist primarily of traditional property and casualty coverages written primarily 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 allocate losses to property and casualty coverages based on internal estimates. In connection with reinsurance contracts, 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. The nature and extent of loss information provided under many facultative (individual risk) or per occurrence excess contracts may be comparable to the information received under a primary insurance contract. However, loss information with respect to aggregate excess-of-loss and quota-share contracts is often in a summary format rather than on an individual claim basis. Loss data includes recoverable paid losses, as well as case loss estimates. Ceding companies infrequently provide reliable IBNR loss estimates. Loss reporting to reinsurers is typically slower in comparison to primary insurers. In the U.S., such 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. In certain countries, clients report annually from 90 to 180 days after the end of the annual 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 for other reasons. 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 certain 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 to audit the reported information. In the normal course of business, disputes occasionally arise concerning whether claims are covered 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. There are no coverage disputes at this time for which an adverse resolution would likely have a material impact on our consolidated results of operations or financial condition. Establishing claim liability estimates for reinsurance assumed 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 case losses and if appropriate, we use our own case liability estimate. For instance, as of December 31, 2021, our case loss estimates exceeded ceding company estimates by approximately $700 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 our case estimates. Although liabilities for losses are initially determined based on pricing and underwriting analysis, we use a variety of actuarial methodologies that place reliance on the extrapolation of actual historical data, loss development patterns, industry data and other benchmarks, as appropriate. 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 and legal environment and the terms and conditions of the contracts. The methodologies generally fall into one of the following categories or are hybrids of one or more of the following categories:

K-60

Management’s Discussion and Analysis (Continued) Property and casualty losses (Continued) Berkshire Hathaway Reinsurance Group (Continued) Paid and incurred loss development methods – these 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 the following: client claims reporting and settlement practices; the frequency of client company claim reviews; policy terms and coverage (such as loss retention levels and occurrence and aggregate policy limits); loss trends; and legal trends that result in unanticipated losses. Collectively, these factors influence our selections of expected case loss emergence patterns. Incurred and paid loss Bornhuetter-Ferguson methods – these methods consider actual paid and incurred losses and expected 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. Frequency and severity methods – these methods commonly focus on a review of the number of anticipated claims and the anticipated claims 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 over time to reflect case losses reported versus expected case losses, which we use to form revised judgement on the adequacy of the expected loss ratio and the level of IBNR liabilities required for unreported claims. Anticipated loss ratios are also revised to include 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 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 the ultimate cost associated with the individual loss event rather than with an analysis of the historical development patterns of past losses. For our long-tail lines, primarily casualty exposures, we may rely on different methods depending on the maturity of the business, with estimates for the most recent years being based on priced loss expectations and more mature years reflecting the paid or incurred development pattern indications. In 2021, certain workers’ compensation claims reported losses were less than expected. As a result, we reduced estimated ultimate losses for prior years’ loss events by $136 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, excluding asbestos, environmental, and other latent injury claims, we reduced estimated ultimate liabilities for prior years’ events by approximately $375 million in 2021. 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 would produce a net increase in our nominal IBNR liabilities and a corresponding reduction in pre- tax earnings of approximately $950 million, although outcomes of greater than or less than $950 million are possible given the diversification in worldwide business. The change in estimated ultimate liabilities for asbestos, environmental and other latent injury claims, excluding amounts assumed under retroactive reinsurance contracts was not significant in 2021. Net liabilities for such claims were approximately $2.1 billion at December 31, 2021. Loss estimations for these exposures are difficult to determine due to the changing legal environment and increases may be required in the future if new exposures or claimants are identified, new claims are reported or new theories of liability emerge.

K-61

Management’s Discussion and Analysis (Continued) Property and casualty losses (Continued) 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 the claim-tails to be very long. As of December 31, 2021, gross unpaid losses were $38.3 billion and deferred charges were $10.6 billion. Our contracts are generally subject to maximum limits of indemnifications and, as such, we currently expect that maximum remaining gross losses payable under our retroactive policies will not exceed $54 billion. Absent significant judicial or legislative changes affecting asbestos, environmental or latent injury 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 estimated gross liability. We establish liability estimates by individual contract, considering exposure and development trends. In establishing our liability estimates, we often analyze historical aggregate loss payment patterns and project expected ultimate losses under various scenarios. We assign judgmental probability factors to these scenarios and an expected outcome is determined. We then monitor subsequent loss payment activity and review ceding company reports and other available information concerning the underlying losses. We re-estimate the expected ultimate losses when significant events or significant deviations from expected results are revealed. Certain of our retroactive reinsurance contracts include asbestos, environmental and other latent injury claims. Our estimated liabilities for such claims were approximately $12.3 billion at December 31, 2021. We do not consistently receive reliable detailed data regarding asbestos, environmental and latent injury claims 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 an estimate of ultimate reinsured losses. When detailed loss information is unavailable, we develop estimates by applying recent industry trends and projections to aggregate client data. Judgments in these areas necessarily consider the stability of the legal and regulatory environment under which we expect claims will be adjudicated. Legal reform and legislation could also have a significant impact on our ultimate liabilities. We reduced estimated ultimate liabilities for prior years’ retroactive reinsurance contracts by $974 million in 2021, which after the changes in related deferred charges, resulted in pre-tax earnings of $142 million. In 2021, we paid losses and loss adjustment expenses of $1.9 billion with respect to our retroactive reinsurance contracts. In connection with our retroactive reinsurance contracts, we also record deferred charges, which at contract inception represents the excess, if any, of the estimated ultimate liability for unpaid losses over premiums received. We amortize deferred charges, which produces charges to pre-tax earnings in future periods based on the expected timing and amount of loss payments. We also adjust deferred charge balances due to changes in the expected timing and ultimate amount of claim payments and the effects of the adjustments are included in pre-tax earnings. Significant changes in such estimates may have a significant effect on unamortized deferred charge balances. Based on the contracts in effect as of December 31, 2021, we estimate that amortization expense in 2022 will approximate $950 million. Other Critical Accounting Policies Our Consolidated Balance Sheet at December 31, 2021 includes goodwill of acquired businesses of $73.9 billion and other indefinite-lived intangible assets of $18.5 billion. We evaluate these assets for impairment annually in the fourth quarter and on an interim basis if the facts and circumstances lead us to believe that more-likely-not there has been an impairment. Goodwill and indefinite-lived intangible asset impairment reviews include determining the estimated fair values of our reporting units and indefinite-lived intangible assets. 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 the indefinite-lived intangible asset exceeds fair value, the excess is charged to earnings as an impairment loss. If the carrying value of a reporting unit exceeds the estimated fair value of the reporting unit, then the excess, limited to the carrying amount of goodwill, will be charged to earnings as an impairment loss.

K-62

Management’s Discussion and Analysis (Continued) Other Critical Accounting Policies (Continued) As of December 31, 2021, we concluded it is 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 severity, duration or long-term effects of the pandemic on the reporting unit’s business, as well as other assumptions concerning the long-term economic performance of the reporting unit, which we cannot reliably predict. Consequently, any fair value estimates in such instances can be subject to wide variations. We primarily use discounted projected future earnings or cash flow methods in determining fair values. The key assumptions and inputs used in such methods may include forecasting revenues and expenses, cash flows and capital expenditures, as well as an appropriate discount rate and other inputs. A significant amount of judgment is required in estimating the fair value of a reporting unit and in performing goodwill impairment tests. In connection with the annual goodwill impairment review conducted in the fourth quarter of 2021, the estimated fair values of five reporting units did not exceed our carrying values by at least 20%. The most significant of these reporting units was Precision Castparts Corp. (“PCC”). The estimated fair value of PCC was approximately $34.5 billion, exceeding our carrying value of approximately $31.1 billion by 10.7%. Our carrying value of PCC included goodwill of approximately $7.5 billion. For the four other reporting units, our aggregate estimated fair value was approximately $2.5 billion, which exceeded our aggregate carrying value of approximately $2.3 billion by 9.2%. Our carrying value of these units included goodwill of approximately $1.2 billion. In the second quarter of 2020, we quantitively reevaluated goodwill for impairment for certain reporting units, and most significantly for PCC. As a result of our reviews, we recorded pre-tax goodwill impairment charges of $10.0 billion and indefinite-lived intangible asset impairment charges of $638 million, of which approximately $10 billion related to PCC. Prior to the reevaluation, the carrying value of PCC-related goodwill was approximately $17 billion. Additionally, the carrying value of PCC-related indefinite-lived intangible assets was approximately $14 billion. Substantially all of these amounts were recorded in connection with Berkshire’s acquisition of PCC in 2016. The initial effects of the COVID-19 pandemic on commercial airlines and aircraft manufacturers were particularly severe. At that time, we considered several factors in our reevaluation, including but not limited to the announcements by airlines concerning potential future demand, employment levels and aircraft orders, announcements by manufacturers of reduced aircraft production, and the actions we were taking or may be taking in the future to restructure operations. Consequently, we deemed it prudent under the prevailing circumstances to increase discount rates and reduce prior long-term forecasts of future cash flows for purposes of reviewing for impairments. Market Risk Disclosures Our Consolidated Balance Sheets include substantial amounts of assets and liabilities whose fair values are subject to market 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 Equity securities represent a 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 prefer to invest a meaningful amount in each company. Historically, equity investments have been concentrated in relatively few issuers. At December 31, 2021, approximately 73% of the total fair value of equity securities was concentrated in four companies. 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 of safety against short-term price volatility.

K-63

Management’s Discussion and Analysis (Continued) Equity Price Risk (Continued) We are also subject to equity price risk with respect to our equity index put option contracts, although our equity price exposure has declined significantly as a vast majority of the contracts written to date have expired. Our ultimate liability with respect to these contracts is determined from the movement of the underlying stock index between the contract inception date and expiration date. The fair values of our liabilities arising from these contracts are also affected by changes in other factors. The following table summarizes our equity securities and equity index put option contract liabilities as of December 31, 2021 and 2020 and the estimated effects of a hypothetical 30% increase and a 30% decrease in market prices as of 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 existing in our equity investment portfolio. Dollar amounts are in millions. Estimated Fair Value after Estimated Hypothetical Hypothetical Increase (Decrease) Fair Value Price Change Change in Prices in Net Earnings (1) December 31, 2021 Investments in equity securities $ 350,719 30% increase $ 452,936 $ 81,136 30% decrease 248,606 (81,053) Equity index put option contract liabilities 99 30% increase 5 74 30% decrease 1,088 (781) December 31, 2020 Investments in equity securities $ 281,170 30% increase $ 362,830 $ 63,321 30% decrease 199,547 (63,293) Equity index put option contract liabilities 1,065 30% increase 257 638 30% decrease 2,702 (1,293) (1) The estimated increase (decrease) is after income taxes at the statutory rate in effect as of the balance sheet date. Interest Rate Risk We may also invest in bonds, loans or other interest rate sensitive instruments. Our strategy is to acquire or originate such instruments at prices considered appropriate relative to the perceived credit risk. We also issue debt in the ordinary course of business to fund business operations, business acquisitions and for other general purposes. We attempt to maintain high credit ratings, in order to minimize the cost of our debt. We infrequently 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. Interest rate risks associated with the valuations of our equity index put option contract liabilities are no longer considered significant due to the short duration of remaining exposures as of December 31, 2021. 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 liquidity of the instrument and other general market conditions.

Management’s Discussion and Analysis (Continued) Interest Rate Risk (Continued) 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 at December 31, 2021 and 2020. We assumed that the interest rate changes occur immediately and uniformly to each category of instrument and that there were no significant changes to other factors used to determine the value of 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 Certain of our subsidiaries operate in foreign jurisdictions and we transact business in foreign currencies. In addition, we hold investments in common stocks of major multinational companies, who have significant foreign business and foreign currency risk of their own. We generally do not attempt to match assets and liabilities by currency and do not use derivative contracts to manage foreign currency risks in a meaningful way.

Management’s Discussion and Analysis (Continued) Foreign Currency Risk (Continued) Our net assets subject to financial statement translation into U.S. Dollars are primarily in our insurance, utilities and energy and certain manufacturing and service subsidiaries. A portion of our financial statement translation-related impact from changes in foreign currency rates is recorded in other comprehensive income. In addition, we include gains or losses from changes in foreign currency exchange rates in net earnings related to non-U.S. Dollar denominated assets and liabilities of Berkshire and U.S.-based subsidiaries. A summary of these gains (losses), after-tax, for each of the years ending December 31, 2021 and 2020 follows (in millions). 2021 2020 Non-U.S. denominated debt included in net earnings $ 955 $ (764) Net liabilities under certain reinsurance contracts included in net earnings 58 (163) Foreign currency translation included in other comprehensive income (1,021) 1,264 Commodity Price Risk Our subsidiaries use commodities in various ways in manufacturing and providing services. As such, we are subject to price risks related to various commodities. In most instances, we attempt to manage these risks through the pricing of our products and services to customers. To the extent that we are unable to sustain price increases in response to commodity price increases, our operating results will likely be adversely affected. We do not utilize derivative contracts to manage commodity price risks to any significant degree. Item 7A. Quantitative and Qualitative Disclosures About Market Risk See “Market Risk Disclosures” contained in Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Management’s Report on Internal Control Over Financial Reporting Management of Berkshire Hathaway Inc. is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in the Securities Exchange Act of 1934 Rule 13a-15(f). Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2021, as required by the Securities Exchange Act of 1934 Rule 13a-15(c). In making this assessment, we used the criteria set forth in the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control—Integrated Framework (2013), our management concluded that our internal control over financial reporting was effective as of December 31, 2021. The effectiveness of our internal control over financial reporting as of December 31, 2021 has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report which appears on page K- 67.

Item 8. Financial Statements and Supplementary Data REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Shareholders and the Board of Directors of Berkshire Hathaway Inc. Omaha, Nebraska 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, 2021 and 2020, the related consolidated statements of earnings, comprehensive income, changes in shareholders’ equity, and cash flows, for each of the three years in the period ended December 31, 2021, 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, 2021, 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 the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO. Basis for Opinions The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying 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 US federal securities laws and the applicable 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 perform the 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 the financial 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 the overall 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 and evaluating 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 the reliability 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 procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions 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 and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; 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.

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 that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are 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, and we 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”) under short duration property and casualty insurance and reinsurance contracts are $86,664 million as of December 31, 2021. The key assumptions affecting certain claim liabilities include expected loss and expense (“loss”) ratios, expected claim count emergence patterns, expected loss payment emergence patterns and expected loss reporting emergence patterns. Given the subjectivity of estimating these key assumptions, performing audit procedures to evaluate whether claim liabilities were appropriately recorded as of December 31, 2021, required a high degree of auditor judgment and an increased 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 claim liabilities included the following, among others: • We tested the operating effectiveness of controls over claim liabilities, including those over the key assumptions. • We evaluated the methods and assumptions used by management to estimate the claim liabilities by: • Testing the underlying data that served as the basis for the actuarial analysis, such as historical claims and earned premium, to test that the inputs to the actuarial estimate were reasonable. • Comparing management’s prior-year claim liabilities to actual development during the current year to identify potential bias in the determination of the claim liabilities. • 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 management’s change in ultimate loss and loss adjustment expense to prior year estimates to test the reasonableness of the prior year estimates and assessed unexpected development. Unpaid Losses and Loss Adjustment Expenses Under Retroactive Reinsurance Contracts — Refer to Notes 1 and 17 to the financial statements Critical Audit Matter Description The Company’s unpaid losses and loss adjustment expenses (“claim liabilities”) for property and casualty retroactive reinsurance contracts are $38,256 million as of December 31, 2021. The key assumptions affecting certain claim liabilities and related deferred charge reinsurance assumed assets (“related assets”) include expected loss and expense (“loss”) ratios, expected loss payment emergence patterns and expected loss reporting emergence. Given the subjectivity of estimating these key assumptions, performing audit procedures to evaluate whether claim liabilities were appropriately recorded as of December 31, 2021, required a high degree of auditor judgment and an increased 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 claim liabilities and related assets included the following, among others: • We tested the operating effectiveness of controls over claim liabilities and related assets, including those over the key assumptions.

K-68

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM (Continued) • We evaluated the methods and assumptions used by management to estimate the claim liabilities and related assets by: • Testing 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 reasonable. • Comparing management’s prior-year claim liabilities to actual development during the current year to identify potential bias in the determination of the claim liabilities and related assets. • With the assistance of our actuarial specialists: • We developed independent claim liability estimates for certain retroactive reinsurance contracts and compared our estimates to management’s estimates. For other retroactive reinsurance contracts and related assets, we evaluated the process used by management to develop the estimated claim liabilities and related assets. • We compared management’s change in ultimate loss and loss adjustment expense to prior year estimates, assessed unexpected development and assessed internal rates of return. 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 the fair value of each reporting unit or asset to its carrying value. The Company evaluates goodwill and indefinite-lived intangible assets for impairment at least annually. When evaluating goodwill and indefinite-lived intangible assets for impairment, the fair value of each reporting unit or asset is estimated. Significant judgment is required in estimating fair values and performing impairment tests. The Company primarily uses discounted projected future net earnings or net cash flows and multiples of earnings to estimate fair value, which requires management to make significant estimates and assumptions related to forecasts of future revenue, earnings before interest and taxes (“EBIT”), and discount rates. Changes in these assumptions could have a significant impact on the fair value of reporting units and indefinite-lived intangible assets. The Precision Castparts Corp. (“PCC”) reporting unit reported approximately $21 billion of goodwill and indefinite-lived intangible assets as of December 31, 2021. Given the significant judgments made by management to estimate the fair value of the PCC reporting unit and certain customer relationships with indefinite lives along with the difference between their fair values and carrying values, performing audit procedures to evaluate the reasonableness of management’s estimates and assumptions related to forecasts of future revenue and EBIT and the selection of the discount rate required a high degree of auditor judgment and an increased extent of effort, including the need to involve our fair value specialists. 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 the forecasts 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 to historical results 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 long-term growth rates and discount rate, including testing the underlying source information and the mathematical accuracy of the calculations, and developed a range of independent estimates and compared those to the long-term growth rates and discount rate selected by management. /s/ Deloitte & Touche LLP Omaha, Nebraska February 26, 2022 We have served as the Company’s auditor since 1985.

BERKSHIRE HATHAWAY INC. and Subsidiaries NOTES TO CONSOLIDATED FINANCIAL STATEMENTS December 31, 2021

(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 a number of 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 25. Information concerning business acquisitions completed over the past three years appears in Note 2. We believe that reporting the Railroad, 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 the accounts 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 and transactions have been eliminated. (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 of assets and liabilities at the balance sheet date and the reported amounts of 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 with the amortization of deferred charges on retroactive reinsurance contracts, determinations of fair values of certain financial instruments and evaluations 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. The novel coronavirus (“COVID-19”) spread rapidly across the world in 2020 and was declared a pandemic by the World Health Organization. The government and private sector responses to contain its spread began to significantly affect our operating businesses in March of 2020. The COVID-19 pandemic adversely affected nearly all of our operations during 2020, although the effects varied significantly. The extent of the effects over longer terms on the demand for certain of our products and services cannot be reasonably estimated at this time. Accordingly, significant estimates used in the preparation of our financial statements including those associated with evaluations of certain long-lived assets, goodwill and other intangible assets for impairment, expected credit losses on amounts owed to us and the estimations 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 three months or less when purchased. Short-term investments in U.S. Treasury Bills consist of U.S. Treasury Bills with maturities exceeding three months at the time of purchase and are stated at amortized cost, which approximates fair value. (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 at fair value. Substantially all of 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 (Continued) (1) Significant accounting policies and practices (Continued) (d) Investments in fixed maturity securities (Continued) We record investment gains and losses on available-for-sale fixed maturity securities when the securities are sold, determined on a specific identification basis. For securities in an unrealized loss position, we recognize a loss in earnings for the excess of amortized cost over fair value if we intend to sell before the price recovers. As of the balance sheet date, we evaluate whether the other 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 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 a credit loss is recognized in other comprehensive income. (e) Investments in equity securities We carry substantially all investments in equity securities at fair value and record the subsequent changes in fair values in the Consolidated Statements of Earnings as a component of investment gains or 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. 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, if any, 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 allowances for 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 as yield adjustments over the lives of the loans. Prior to 2020, credit losses were measured when non-collection was considered probable based on the prevailing facts and circumstances. Beginning in 2020, measurements of expected credit losses include provisions for non- collection, whether the risk is probable or remote. 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 past due 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 a loan is less than 90 days delinquent. Loans are considered non-performing when the foreclosure process has started. Once a loan is in the process of foreclosure, interest income is not recognized until the foreclosure is cured or the loan is modified. Once a modification is complete, interest income is recognized based on the terms of the new loan. Foreclosed loans are charged off when the collateral is sold. Loans not in foreclosure are evaluated for charge-off based on individual circumstances concerning the future collectability of the loan and the condition of the collateral securing the loan.

K-76

Notes to Consolidated Financial Statements (Continued) (1) Significant accounting policies and practices (Continued) (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 premium receivables and other receivables are primarily 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 government-sponsored insurance programs. Reinsurance recoverables relate to unpaid losses and loss adjustment expenses arising from property and casualty contracts and benefits under life and health contracts. Receivables are stated net of estimated allowances for uncollectible balances. Prior to 2020, we recorded provisions for uncollectible balances when it was probable counterparties or customers would be unable to pay all amounts due based on the contractual terms and historical loss history. Beginning in 2020, we adopted a new accounting pronouncement that affects the measurement of allowances for credit losses. In measuring credit loss allowances, we primarily utilize credit loss history, with adjustments to reflect current or expected future economic conditions when reasonable and supportable forecasts of losses deviate from historical experience. 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 all reasonable collection efforts are exhausted. (i) Derivatives We carry derivative contracts in accounts payable, accruals and other liabilities in our Consolidated Balance Sheets at fair value, net of reductions permitted under master netting 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 in estimating fair value. Alternative valuation techniques may be appropriate under the circumstances to determine the value that 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, 2021, we used the last-in-first-out (“LIFO”) method to value approximately 31% 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 of cost or net realizable value. The excess of current or replacement costs over costs determined under LIFO was approximately $1.9 billion as of December 31, 2021 and $1.1 billion as of December 31, 2020. (l) Property, plant and equipment We record additions to property, plant and equipment used in operations at cost, which includes asset additions, improvements and betterments. 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 of our 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 finance the construction of the regulated facilities. Normal repairs and maintenance and other costs that do not improve the property, extend its useful life or otherwise do not meet capitalization criteria are charged to expense as incurred.

Notes to Consolidated Financial Statements (Continued) (1) Significant accounting policies and practices (Continued) (l) Property, plant and equipment (Continued) 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 group depreciation, a composite rate is applied to the gross investment in a particular class of property, despite differences in the 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. We depreciate property, plant and equipment used by our other businesses to the estimated salvage value primarily using the straight-line method over estimated useful lives. Ranges of estimated useful lives of depreciable assets used in our other businesses are as follows: buildings and improvements – 5 to 50 years, machinery and equipment – 3 to 25 years and furniture, fixtures and other – 3 to 15 years. 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 43 years. Ranges of estimated useful lives of assets unique to our regulated 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 and independent power plants and other assets – 2 to 50 years. We evaluate property, plant and equipment 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 for sale. Upon the occurrence of a triggering event, we assess whether the estimated undiscounted cash flows expected from the use of the asset and the residual value from the ultimate disposal of the asset exceeds the carrying value. If the carrying 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) Leases We are party to contracts where we lease property to others (“lessor” contracts) and where we lease property from others (“lessee” contracts). We record acquisitions of and additions to equipment that we lease to others at cost. We depreciate equipment held for lease 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 is greater during the earlier years of its life. We also evaluate equipment held for lease for impairment consistent with policies for property, plant and equipment. When we lease assets from others, we record right-of-use assets and lease liabilities. Right-of-use assets represent our right to use an underlying asset for the lease term and lease 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 generally considered the non-cancellable 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 lease liabilities. Right-of-use assets are subject to review for impairment. As permitted under GAAP, we do not separate lease components from non-lease components by class of asset and do not record assets or liabilities for leases 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 fair value 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 not limited 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 is charged to earnings as an impairment loss. 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 or changes in circumstances indicate that the carrying amount may not be recoverable. K-78

Notes to Consolidated Financial Statements (Continued) (1) Significant accounting policies and practices (Continued) (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. Premiums are generally earned in proportion to the coverage provided, which is generally ratable 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 generally received in full and are 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 usually received in full 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 under such 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 these products 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 performance obligations, we allocate the revenue to each obligation based on the relative stand-alone selling prices of each product or service. Sales revenue reflects reductions for returns, allowances, volume discounts and other incentives, some of which may be contingent on future events. In certain customer contracts, sales revenue includes 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 revenue excludes sales taxes and value-added taxes collected on behalf of taxing authorities. Sales revenue includes consideration for shipping and other fulfillment activities performed prior to the customer 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. Our product sales revenues are generally recognized at a point in time when control of the product transfers to the customer, which coincides with customer pickup or product delivery or acceptance, depending on terms of the arrangement. We recognize sales revenues and related costs with respect to certain contracts over time, primarily from certain castings, forgings and aerostructures contracts. Control of the product units under these contracts transfers continuously to the customer as the product is manufactured. These products generally have no alternative use and the contract requires the customer to provide reasonable compensation if terminated for reasons other than breach of contract. The primary performance obligation under our freight rail transportation service contracts is to move freight from a point of origin to a point of destination. The performance obligations are represented by bills of lading which create a series of distinct services that have a similar pattern of transfer to the customer. The revenues for each performance obligation 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 road agreements 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 proportion 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-rata basis based on actual or projected future customer shipments.

Notes to Consolidated Financial Statements (Continued) (1) Significant accounting policies and practices (Continued) (o) Revenue recognition (Continued) Our energy revenue derives primarily from tariff-based sales arrangements approved by various regulatory commissions. These tariff-based revenues are mainly comprised of energy, transmission, distribution and natural 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. Our nonregulated energy revenue primarily relates to our renewable energy business. Energy revenues are equivalent to the amounts we have the right to invoice and correspond directly with the value to the customer of the performance to date and include billed and unbilled amounts. Payments from customers are generally due within 30 days of billing. Rates charged for 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 to refund and a liability for estimated refunds is accrued. Other service revenues derive from contracts with customers in which performance obligations are satisfied over time, where customers receive and consume benefits as we perform the services or at a point in time when the services are provided. Other service revenues primarily derive from real estate brokerage, automotive repair, aircraft management, aviation training, franchising 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 and reinsurance contracts for loss events that have occurred on or before the balance sheet date. Such liabilities represent the estimated 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 of Earnings include paid claims, claim settlement costs and changes in estimated claim liabilities. Losses and loss adjustment expenses charged to earnings are net of amounts recovered and estimates of amounts 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 to retroactive reinsurance contracts, we also record deferred charge assets at the inception of the contracts, representing the excess, if any, of the estimated ultimate claim liabilities over the premiums earned. We subsequently amortize the deferred charge assets over the expected claim settlement periods using the interest method. Changes to the estimated timing or amount of future loss payments also produce changes in deferred charge balances. We apply changes in such estimates retrospectively and the resulting changes in deferred charge balances, together with periodic amortization, are included in insurance losses and loss adjustment expenses in the Consolidated Statements of Earnings. (r) Insurance policy acquisition costs We capitalize the incremental costs that directly relate to the successful sale of insurance contracts, subject to ultimate recoverability. For short duration contracts, we subsequently amortize such costs to underwriting expenses as the related premiums are earned. Acquisition costs related to long duration life insurance contracts are amortized over the expected premium-paying period in proportion to the anticipated premiums over the life of the policy. Such anticipated premiums are estimated using the same assumptions used for computing liabilities for future policy benefits. Direct incremental acquisition costs include commissions, premium taxes and certain other costs associated with successful efforts. We expense all other underwriting costs as incurred. The recoverability of capitalized insurance policy acquisition costs generally reflects anticipation of investment income. The unamortized balances are included in other assets and were approximately $3.4 billion and $3.25 billion at December 31, 2021 and 2020, respectively.

K-80

Notes to Consolidated Financial Statements (Continued) (1) Significant accounting policies and practices (Continued) (s) Life and annuity insurance benefits We compute liabilities for benefits under life insurance contracts based upon estimated future investment yields, expected mortality, morbidity and lapse or withdrawal rates, as well as estimates of premiums we expect to receive and expenses we expect to incur in the future. These assumptions, as applicable, also include a margin for adverse deviation and may vary with the characteristics of the contract’s date of issuance, policy duration and country of risk. The interest rate assumptions used may vary by contract or jurisdiction. We discount periodic payment annuity liabilities based on the implicit rate as of the inception of the contracts such that the present value of the liabilities equals the premiums. Discount rates for most contracts range from 3% to 7%. (t) Regulated utilities and energy businesses Certain energy subsidiaries prepare their financial statements in accordance with authoritative guidance for regulated 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 by considering 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 to customers. (u) Foreign currency The accounts of our non-U.S. based subsidiaries are measured, in most instances, 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 component of accumulated other comprehensive income. Gains and losses arising from transactions denominated in a currency other than the functional currency of the reporting 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 United States, which includes eligible subsidiaries. In addition, we file income tax returns in state, local and foreign jurisdictions as applicable. 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 and tax bases of assets and liabilities at the enacted tax rates. Changes in deferred income tax assets and liabilities associated with 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 to income tax expense in the period of enactment. Valuation allowances are established for certain deferred tax assets when realization is not likely. Assets and 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 the positions. Estimated interest and penalties related to uncertain tax positions are included as a component of income tax expense.

Notes to Consolidated Financial Statements (Continued) (1) Significant accounting policies and practices (Continued) (w) New accounting pronouncements adopted in 2020 We adopted Accounting Standards Codification (“ASC”) 326 “Financial Instruments-Credit Losses” on January 1, 2020. ASC 326 provides for the measurement of expected credit losses on financial assets that are carried at amortized cost based on the net amounts expected to be collected. Measurements of expected credit losses therefore include provisions for non-collection, whether the risk is probable or remote. Prior to the adoption of ASC 326, credit losses were measured when non-collection was considered probable. Upon adoption of ASC 326, we recorded a charge to retained earnings of $388 million representing the cumulative after-tax increase in our allowances for credit losses. (x) New accounting pronouncements adopted in 2019 Berkshire adopted ASC 842 “Leases” on January 1, 2019 with respect to contracts in effect as of the adoption and elected to not restate prior period financial statements. Most significantly, ASC 842 requires a lessee to recognize a liability to make operating lease payments and an asset with respect to its right to use the underlying asset for the lease term. Upon adoption, we recorded operating lease right-of-use assets of approximately $6.2 billion, lease liabilities of $5.9 billion and reduced other assets by approximately $300 million. (y) New accounting pronouncements to be adopted subsequent to December 31, 2021 In August 2018, the Financial Accounting Standards Board issued Accounting Standards Update 2018-12 “Targeted Improvements to the Accounting for Long-Duration Contracts” (“ASU 2018-12”). ASU 2018-12 requires reassessment of cash flow assumptions at least annually and revision of discount rate assumptions each reporting period in valuing policyholder liabilities and related deferred acquisition costs of long-duration insurance and reinsurance contracts. The effects from changes in cash flow assumptions are reflected in earnings and the effects from changes in discount rate assumptions are reflected in other comprehensive income. Currently, the cash flow and discount rate assumptions are set at the contract inception date and not subsequently changed, except under limited circumstances. ASU 2018-12 is to be applied retrospectively to the earliest period presented in the financial statements, requires new disclosures and is effective for fiscal years beginning after December 15, 2022, with early adoption permitted. We currently intend to adopt ASU 2018-12 as of January 1, 2023 using the modified retrospective method, which provides that the revised cash flow and discount rate assumptions as of January 1, 2021 (the transition date) be applied to contracts then in-force, with liabilities then remeasured as provided under the standard. The cumulative effects from discount rate assumption changes as of the transition date will be reflected in accumulated other comprehensive income and the cumulative effect from cash flow assumption changes will be included in retained earnings. While we have not finalized our assessment of the impact of the adoption as of the transition date, we currently believe that the changes in discount rate assumptions will have a greater effect on our recorded liabilities than changes in cash flow assumptions. We also preliminarily estimate that the changes in discount rate assumptions as of January 1, 2021 will increase our life, health and annuity benefit liabilities from the amounts previously reported due to the historically low interest rate environment at that time. However, the ultimate impact of adopting ASU 2018-12 will be based on the discount rate and cash flow assumptions determined as of the January 1, 2023 adoption date. We, therefore, continue to evaluate the effect this standard will have on our Consolidated Financial Statements. (2) 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. Berkshire Hathaway Energy (“BHE”) acquired certain businesses of Dominion Energy, Inc. (“Dominion”) on November 1, 2020, pursuant to a definitive agreement with Dominion in July 2020. The acquired businesses included natural gas transmission, gathering and storage pipelines, natural gas storage capacity and partial ownership of a liquefied natural gas export, import and storage facility (“Cove Point”). In October 2020, BHE and Dominion also agreed to provide for the exclusion of certain pipeline businesses from the initial agreement and entered into a second acquisition agreement with respect to the excluded pipeline businesses. The closing of the second agreement was subject to regulatory and customary closing conditions; however, in July 2021, BHE and Dominion agreed to terminate the second agreement.

Notes to Consolidated Financial Statements (Continued) (2) Business acquisitions (Continued) The cost of the acquisition was approximately $2.5 billion after post-closing adjustments as provided in the agreement. The fair values of identified assets acquired and liabilities assumed and residual goodwill are summarized as follows (in millions). Property, plant and equipment $ 9,264 Goodwill 1,741 Other 2,398 Assets acquired $ 13,403 Notes payable and other borrowings $ 5,615 Other 1,358 Liabilities assumed 6,973 Noncontrolling interests 3,916 Net assets $ 2,514

As part of this acquisition, BHE acquired an indirect 25% economic interest in Cove Point, consisting of 100% of the general partnership interest and 25% of the limited partnership interests. We concluded that Cove Point is a VIE and that we have the power to direct the activities that most significantly impact its economic performance as well as the obligation to absorb losses and receive benefits which could be significant to Cove Point. Therefore, we treat Cove Point as a consolidated subsidiary. The noncontrolling interests are attributable to the limited partner interests held by third parties. In each of the past three years, we also completed several smaller-sized business acquisitions, which we consider as “bolt-ons” to several of our existing business operations. We do not believe that these acquisitions are material, individually or in the aggregate to our Consolidated Financial Statements. (3) Investments in fixed maturity securities Investments in fixed maturity securities as of December 31, 2021 and 2020 are summarized by type below (in millions).

Investments in foreign governments include securities issued by national and provincial government entities as well as instruments that are unconditionally guaranteed by such entities. As of December 31, 2021, approximately 93% of our foreign government holdings were rated AA or higher by at least one of the major rating agencies. The amortized cost and estimated fair value of fixed maturity securities at December 31, 2021 are summarized below by contractual maturity dates. Amounts are in millions.

$18.3 billion; Apple Inc. – $120.4 billion; Bank of America Corporation – $31.3 billion and The Coca-Cola Company – $21.9 billion). Investments in commercial, industrial and other equity securities include our investments in Occidental Corporation (“Occidental”), which we acquired in 2019. These investments were acquired for a total of $10 billion and consist of Occidental Cumulative Perpetual Preferred Stock with an aggregate liquidation value of $10 billion and warrants, which currently permit us to purchase up to 83.86 million shares of Occidental common stock at an exercise price of $59.62 per share. The 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 preference plus any accumulated and unpaid dividends and is mandatorily redeemable under certain specified events. The warrants are exercisable in whole or in part until one year after the redemption of the preferred stock. (5) 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 is our investment in the common stock of The Kraft Heinz Company (“Kraft Heinz”). Kraft Heinz is one of the world’s largest manufacturers and marketers of food and beverage products, including condiments and sauces, cheese and dairy, meals, meats, refreshment beverages, coffee and other grocery products. Berkshire currently owns 26.6% of the outstanding shares of Kraft Heinz common stock. We recorded equity method earnings from our investment in Kraft Heinz of $269 million in 2021, $95 million in 2020 and $493 million in 2019. Equity method earnings included the effects of goodwill and identifiable intangible asset impairment charges recorded by Kraft Heinz. Our share of such charges was approximately $350 million in 2021, $850 million in 2020 and $450 million in 2019. We received dividends from Kraft Heinz of $521 million in each of 2021, 2020 and 2019, which we recorded as reductions in our carrying value. Shares of Kraft Heinz common stock are publicly-traded and the fair value of our investment was approximately $11.7 billion at December 31, 2021 and $11.3 billion at December 31, 2020. The carrying value of our investment was approximately $13.1 billion at December 31, 2021 and $13.3 billion at December 31, 2020. As of December 31, 2021, the carrying value of our investment exceeded the fair value based on the quoted market price by approximately 11% of the carrying value. We evaluated our investment in Kraft Heinz for impairment. Based on the prevailing facts and circumstances, we concluded recognition of an impairment charge in earnings was not required as of December 31, 2021.

Other investments accounted for pursuant to the equity method include our investments in Berkadia Commercial Mortgage LLC (“Berkadia”), Pilot Travel Centers LLC (“Pilot”), Electric Transmission Texas, LLC (“ETT”) and beginning in 2021, Iroquois Gas Transmission System L.P. (“Iroquois”). The aggregate carrying value of our investments in these entities was $4.3 billion as of December 31, 2021 and $4.0 billion as of December 31, 2020. Our equity method earnings in these entities were $726 million in 2021, $631 million in 2020 and $683 million in 2019. During 2021, we received distributions of approximately $1.2 billion from these investees. Additional information concerning these investments follows. We own a 50% interest in Berkadia, with Jefferies Financial Group Inc. (“Jefferies”) owning the other 50% interest. Berkadia is a servicer of commercial real estate loans in the U.S., performing primary, master and special servicing functions for U.S. government agency programs, commercial mortgage-backed securities transactions, banks, insurance companies and other financial institutions. Berkadia funds a portion of its operations through commercial paper borrowings, which are currently limited to $1.5 billion. On December 31, 2021, Berkadia’s commercial paper outstanding was $1.47 billion. Berkadia’s commercial paper 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. BHE subsidiaries own a 50% noncontrolling interest in ETT, an owner and operator of electric transmission assets in Texas and a 50% noncontrolling interest in Iroquois, which owns and operates a natural gas pipeline located in New York and Connecticut. We own a 38.6% interest in Pilot, headquartered in Knoxville, Tennessee. Pilot is the largest operator of travel centers in North America with more than 800 retail locations across 44 U.S. states and six Canadian provinces and through wholesale distribution. Pilot’s revenues in 2021 were approximately $45 billion. The Haslam family currently owns a 50.1% interest in Pilot and a third party owns the remaining 11.3% interest. We have an agreement to acquire in 2023 an additional 41.4% interest in Pilot with the Haslam family retaining a 20% interest. As a result, Berkshire will become the majority owner of Pilot in 2023. (6) Investment and derivative contract gains/losses Investment and derivative contract gains/losses for each of the three years ending December 31, 2021 are summarized as follows (in millions). 2021 2020 2019 Investment gains (losses): Equity securities: Change in unrealized investment gains (losses) during the year on securities held at the end of the year $ 76,375 $ 54,951 $ 69,581 Investment gains (losses) during the year on securities sold 997 (14,036) 1,585 77,372 40,915 71,166 Fixed maturity securities: Gross realized gains 85 56 87 Gross realized losses (29) (27) (25) Other 148 (39) (105) Investment gains (losses) 77,576 40,905 71,123 Derivative contract gains (losses) 966 (159) 1,484 $ 78,542 $ 40,746 $ 72,607

Notes to Consolidated Financial Statements (Continued) (6) Investment and derivative contract gains/losses (Continued) Equity securities gains and losses include unrealized gains and losses from changes in fair values during the year on equity securities we still owned at the end of the year, as well as gains and losses on securities we sold during the year. As reflected in the Consolidated Statements of Cash Flows, we received proceeds of approximately $15.8 billion in 2021, $38.8 billion in 2020 and $14.3 billion in 2019 from sales of equity securities. 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 the applicable 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 original cost. Taxable gains were $3.6 billion in 2021, $6.2 billion in 2020 and $3.2 billion in 2019. The derivative contract gains and losses derive from equity index put option contracts written prior to March 2008 on four major equity indexes. Information related to these contracts follows (dollars in millions). December 31, 2021 2020 Balance sheet liabilities - at fair value $ 99 $ 1,065 Notional value 6,992 10,991 Intrinsic value — 727 Weighted average remaining life (in years) 0.5 1.2 Notional value in the preceding table represents the aggregate undiscounted amounts payable assuming the value of each index is zero on each contract’s expiration date. Intrinsic value is the undiscounted liability assuming the contracts are settled based on the index values and foreign currency exchange rates as of the balance sheet date. Contracts comprising 63% of the notional value as of December 31, 2021 will expire in the first quarter of 2022. Future payments, if any, under any given contract will be required if the index value is below the contract strike price at the contract expiration date. We received aggregate premiums on the contract inception dates of $1.3 billion with respect to unexpired contracts as of December 31, 2021 and we have no counterparty credit risk.

Notes to Consolidated Financial Statements (Continued) (7) Loans and finance receivables (Continued) We are also party to commercial loan agreements with Seritage Growth Properties (“Seritage”) and Lee Enterprises, Inc, (“Lee”), in which loan balances aggregated $1.9 billion at December 31, 2021 and $2.1 billion at December 31, 2020. The Seritage loan is pursuant to a $2.0 billion term loan facility and the outstanding loan is secured by mortgages on its real estate properties. During the fourth quarter of 2021, the loan agreement with Seritage was amended to allow optional loan prepayments without penalty and on December 31, 2021, Seritage made a loan prepayment of $160 million. The amendments further provide Seritage with the option to extend the maturity of the loan to July 31, 2025, if the outstanding principal has been reduced to $800 million by the original expiration date of July 31, 2023. The loan to Lee matures in 2045 and was made in connection with its acquisition of our newspaper operations and the repayment by Lee of its then outstanding credit facilities. We are the sole lender to each of these entities and each of these loans is current as to payment status. (8) Other receivables Other receivables are comprised of the following (in millions).

• Net of accumulated goodwill impairments of $11.0 billion as of December 31, 2021 and 2020.

During 2020, we reevaluated goodwill and indefinite-lived intangible assets of certain of our reporting units for impairment due to the disruptions arising from the COVID-19 pandemic, which we believed most significantly affected the air travel, commercial aerospace and supporting industries. We recorded goodwill impairment charges of approximately $10 billion and indefinite-lived intangible asset impairment charges of $638 million in the second quarter of 2020. Approximately $10 billion of these charges pertained to Precision Castparts Corp. (“PCC”), one of the largest businesses within Berkshire’s manufacturing segment. The carrying values of PCC-related goodwill and indefinite-lived intangible assets prior to the impairment charges were approximately $31 billion. The impairment charges were determined based on discounted cash flow methods and reflected our assessments of the risks and uncertainties associated with the aerospace industry. Significant judgment is required in estimating the fair value of a reporting unit and in performing impairment tests. Due to the inherent uncertainty in forecasting future cash flows and earnings, actual results in the future may vary significantly from the forecasts.

Intangible asset amortization expense was $1,252 million in 2021, $1,277 million in 2020 and $1,317 million in 2019. Estimated amortization expense over the next five years is as follows (in millions): 2022 – $1,189; 2023 – $1,120; 2024 – $1,023; 2025 – $939 and 2026 – $846. Intangible assets with indefinite lives were $18.5 billion as of December 31, 2021 and $18.3 billion as of December 31, 2020 and primarily related to certain customer relationships and trademarks and trade names. (14) Supplemental cash flow information A summary of supplemental cash flow information for each of the three years ending December 31, 2021 is presented in the following table (in millions). 2021 2020 2019 Cash paid during the year for: Income taxes $ 5,412 $ 5,001 $ 5,415 Interest: Insurance and other 1,227 1,001 1,011 Railroad, utilities and energy 3,162 3,006 2,879 Non-cash investing and financing activities: Liabilities assumed in connection with business acquisitions 102 6,981 766 Operating lease liabilities arising from obtaining right-of-use assets 687 729 782 (15) Dividend restrictions – Insurance subsidiaries Payments of dividends by our insurance subsidiaries are restricted by insurance statutes and regulations. Without prior regulatory approval, our principal insurance subsidiaries may declare up to approximately $30 billion as ordinary dividends during 2022. 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 $6.4 billion at December 31, 2021 and $5.5 billion at December 31, 2020. Combined shareholders’ equity of U.S. based insurance subsidiaries determined pursuant to statutory accounting rules (Surplus as Regards Policyholders) was approximately $301 billion at December 31, 2021 and $237 billion at December 31, 2020. 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, 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.

Notes to Consolidated Financial Statements (Continued) (16) Unpaid losses and loss adjustment expenses Our liabilities for unpaid losses and loss adjustment expenses (also referred to as “claim liabilities”) under property and casualty insurance and reinsurance contracts are based upon estimates of the ultimate claim costs associated with claim occurrences as of the balance sheet date and include estimates for incurred-but-not-reported (“IBNR”) claims. A reconciliation of the changes in claim liabilities, excluding liabilities under retroactive reinsurance contracts (see Note 17), for each of the three years ending December 31, 2021 is as follows (in millions). 2021 2020 2019 Balances at beginning of year: Gross liabilities $ 79,854 $ 73,019 $ 68,458 Reinsurance recoverable on unpaid losses (2,912) (2,855) (3,060) Net liabilities 76,942 70,164 65,398 Incurred losses and loss adjustment expenses: Current accident year 52,099 43,400 43,335 Prior accident years (3,116) (356) (752) Total 48,983 43,044 42,583 Paid losses and loss adjustment expenses: Current accident year (22,897) (17,884) (19,482) Prior accident years (18,904) (18,862) (17,642) Total (41,801) (36,746) (37,124) Foreign currency effect (420) 480 (23) Business acquisition (disposition) — — (670) Balances at December 31: Net liabilities 83,704 76,942 70,164 Reinsurance recoverable on unpaid losses 2,960 2,912 2,855 Gross liabilities $ 86,664 $ 79,854 $ 73,019

Incurred losses and loss adjustment expenses shown in the preceding table were recorded in earnings and related to insured events occurring in the current year (“current accident year”) and events occurring in all prior years (“prior accident years”). Incurred and paid losses and loss adjustment expenses are net of reinsurance recoveries. Current accident year incurred losses included approximately $2.9 billion in 2021, $950 million in 2020 and $1.0 billion in 2019 from significant catastrophe events (losses in excess of $100 million per event) occurring in the respective year. Current accident year incurred losses from private passenger auto insurance also increased significantly in 2021 as compared to 2020, primarily due to increased claims frequencies and severities. In 2020, current accident year incurred losses reflected low private passenger auto claims frequencies and increased loss estimates for certain commercial insurance and reinsurance business attributable to the COVID-19 pandemic. We recorded net reductions of estimated ultimate liabilities for prior accident years of $3.1 billion in 2021, $356 million in 2020 and $752 million in 2019, which produced corresponding reductions in incurred losses and loss adjustment expenses in those periods. These reductions, as percentages of the net liabilities at the beginning of each year, were 4.0% in 2021, 0.5% in 2020 and 1.1% in 2019. Estimated ultimate liabilities for prior accident years from primary insurance were reduced by $2.4 billion in 2021, $518 million in 2020 and $457 million in 2019. The reductions in 2021 and 2020 derived primarily from private passenger auto and medical professional liability claims. In both 2021 and 2020, we also lowered estimated ultimate liabilities for prior accident years with respect to workers’ compensation claims, which were largely offset by increases in ultimate liabilities for other casualty claims. The decrease in incurred losses for prior accident years in 2019 reflected reductions in medical professional liability and workers’ compensation estimates partially offset by higher other casualty estimates. Estimated ultimate liabilities for prior accident years related to property and casualty reinsurance decreased $718 million in 2021, increased $162 million in 2020 and decreased $295 million in 2019. The increase in 2020 included increased claims estimates for legacy casualty exposures.

Notes to Consolidated Financial Statements (Continued) (16) Unpaid losses and loss adjustment expenses (Continued) Estimated net claim liabilities for environmental, asbestos and other latent injury exposures were approximately $2.1 billion at December 31, 2021 and 2020. These liabilities are subject to change due to changes in the legal and regulatory environment. We are unable to reliably estimate additional losses or a range of losses that are reasonably possible for these claims. Disaggregated information concerning our claims liabilities is provided below and in the pages that follow. The effects of businesses acquired or disposed during the year are reflected in the data presented on a retrospective basis. A reconciliation of the disaggregated net unpaid losses and allocated loss adjustment expenses (the latter referred to as “ALAE”) of GEICO, Berkshire Hathaway Primary Group (“BH Primary”) and Berkshire Hathaway Reinsurance Group (“BHRG”) to our consolidated unpaid losses and loss adjustment expenses as of December 31, 2021 follows (in millions).

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 and for large volumes of minor physical damage claims that once reported are quickly settled. We establish case loss estimates for liability claims, including estimates for loss adjustment expenses, as the facts and merits of the claim are evaluated. Claim estimates for liability coverages normally reflect greater uncertainty than 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. The “claim-tail” is the period between the claim occurrence date and claim settlement or payment date. Consequently, we establish additional case development liabilities, which are usually percentages of the case liabilities. For unreported claims, IBNR liabilities are estimated by projecting the ultimate number of claims expected (reported and unreported) for each significant coverage and deducting reported claims to produce estimated unreported claims. The product of the average cost per unreported claim and the number of unreported claims produces the IBNR liability estimate. We may record supplemental IBNR liabilities in certain situations when actuarial techniques are difficult to apply.

IBNR and case development liabilities are as of December 31, 2021. Claim counts are established when accidents that may result in a liability are reported and are based on policy coverage. Each claim event may generate claims under multiple coverages, and thus may result in multiple counts.

Notes to Consolidated Financial Statements (Continued) (16) Unpaid losses and loss adjustment expenses (Continued) Workers’ Compensation and Other Casualty We periodically evaluate ultimate loss and loss adjustment expense estimates for the workers’ compensation and other casualty claims using a combination of commonly accepted actuarial methodologies such as the Bornhuetter-Ferguson and chain-ladder approaches using paid and incurred loss data. Paid and incurred loss data is segregated and analyzed by state due to 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 and the costs of claims investigations and administration. We establish case liabilities for reported claims based upon the facts and circumstances 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.

BHRG We use a variety of methodologies to establish BHRG’s estimates for property and casualty claims liabilities. These methodologies include paid and incurred loss development techniques, incurred and paid loss Bornhuetter-Ferguson techniques and frequency and severity techniques, as well as ground-up techniques when appropriate. Our claims liabilities are principally a function of reported losses from ceding companies, case development and IBNR liability estimates. Case loss estimates are reported under our contracts 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, we may establish case liabilities based on our estimates.

K-95

Notes to Consolidated Financial Statements (Continued) (16) Unpaid losses and loss adjustment expenses (Continued) Estimated IBNR liabilities are affected by expected case loss emergence patterns and expected loss ratios, which are evaluated 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 individual loss event. Claim count data is not provided consistently by ceding companies under our contracts or is otherwise considered unreliable. 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, 2021. Dollars are in millions.

Notes to Consolidated Financial Statements (Continued) (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. Claims payments may commence immediately after the contract date or, when applicable, after a contractual retention amount has been reached. Reconciliations of the changes in estimated liabilities for retroactive reinsurance unpaid losses and loss adjustment expenses (“claim liabilities”) and related deferred charge reinsurance assumed assets for each of the three years ended December 31, 2021 follow (in millions). 2021 2020 2019 Unpaid losses Deferred Unpaid losses Deferred Unpaid losses Deferred and loss charges - and loss charges - and loss charges - adjustment retroactive adjustment retroactive adjustment retroactive expenses reinsurance expenses reinsurance expenses reinsurance Balances at beginning of year $ 40,966 $ (12,441) $ 42,441 $ (13,747) $ 41,834 $ (14,104) Incurred losses and loss adjustment expenses: Current year contracts 153 (17) — — 1,138 (453) Prior years’ contracts (974) 1,819 (399) 1,306 378 810 Total (821) 1,802 (399) 1,306 1,516 357 Paid losses and loss adjustment expenses (1,889) — (1,076) — (909) — Balances at December 31 $ 38,256 $ (10,639) $ 40,966 $ (12,441) $ 42,441 $ (13,747) Incurred losses and loss adjustment expenses, net of deferred charges $ 981 $ 907 $ 1,873

In the preceding table, classifications of incurred losses and loss adjustment expenses are based on the inception dates of the contracts, which reflect when our exposures to losses began. We do not believe that analysis of losses incurred and paid by accident year of the underlying event is relevant or meaningful given that our exposure to losses incepts when the contract incepts. Further, we believe the classifications of reported claims and case development liabilities have little or no practical analytical value. Currently, our largest retroactive reinsurance contract is between our subsidiary, National Indemnity Company, and certain subsidiaries of American International Group, Inc. (collectively, “AIG”). Our estimated unpaid claim liabilities with regard to the AIG contract were approximately $15.8 billion at December 31, 2021 and $17.7 billion at December 31, 2020. Claim payments under this contract commenced in 2021 and were $1.2 billion during 2021. Deferred charges related to the AIG contract were approximately $4.5 billion at December 31, 2021 and $5.4 billion at December 31, 2020. Incurred losses and loss adjustment expenses related to contracts written in prior years were $845 million in 2021, $907 million in 2020 and $1,188 million in 2019, which included recurring amortization of deferred charges and the effect of changes in the timing and amount of expected future loss payments. 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 other information concerning the underlying losses. We reassess and revise the expected timing and amounts of ultimate losses periodically or when significant events are revealed through our monitoring and review processes. Estimated claim liabilities for retroactive reinsurance included estimates for environmental, asbestos and other latent injury exposures of approximately $12.3 billion at December 31, 2021 and $12.5 billion at December 31, 2020. Retroactive reinsurance contracts are generally subject to aggregate policy limits and thus, our exposure to such claims under these contracts is likewise limited. We monitor evolving case law and its effect on environmental and other latent injury claims. Changing laws or government regulations, newly identified toxins, 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 results of operations. We are unable to reliably estimate the amount of additional net loss or the range of net loss that is reasonably possible.

Notes to Consolidated Financial Statements (Continued) (18) Notes payable and other borrowings Notes payable and other borrowings are summarized below (in millions). The weighted average interest rates and maturity date ranges shown in the following tables are based on borrowings as of December 31, 2021. Weighted Average December 31, Interest Rate 2021 2020 Insurance and other: Berkshire Hathaway Inc. (“Berkshire”): U.S. Dollar denominated due 2022-2047 3.3% $ 6,820 $ 8,308 Euro denominated due 2023-2041 1.0% 7,792 8,326 Japanese Yen denominated due 2023-2060 0.6% 6,797 6,031 Berkshire Hathaway Finance Corporation (“BHFC”): U.S. Dollar denominated due 2022-2051 3.6% 10,758 10,766 Great Britain Pound denominated due 2039-2059 2.5% 2,325 2,347 Other subsidiary borrowings due 2022-2045 4.0% 4,438 4,682 Short-term subsidiary borrowings 2.9% 342 1,062 $ 39,272 $ 41,522

During 2021, Berkshire repaid €550 million and $1.5 billion of maturing senior notes and issued €600 million of 0.5% senior notes due in 2041 and ¥160 billion (approximately $1.5 billion) of senior notes with maturity dates ranging from 2026 to 2041 and a weighted average interest rate of 0.5%. In January 2022, Berkshire repaid $600 million of maturing debt and issued ¥128.5 billion (approximately $1.1 billion) of senior notes with maturity dates ranging from 2027 to 2052 and a weighted average interest rate of 0.5%. Borrowings of BHFC, a wholly owned finance subsidiary of Berkshire, consist of senior unsecured notes used to fund manufactured housing loans originated or acquired and equipment held for lease of certain subsidiaries. BHFC borrowings are fully and unconditionally guaranteed by Berkshire. In 2021, BHFC repaid $750 million of maturing senior notes and issued $750 million of 2.5% senior notes due in 2051. The carrying values of Berkshire and BHFC non-U.S. Dollar denominated senior notes (€6.9 billion, £1.75 billion and ¥785.5 billion par) reflect the applicable exchange rates as of the balance sheet dates. The effects of changes in foreign currency exchange rates during the period are recorded in earnings as a component of selling, general and administrative expenses. Changes in the exchange rates resulted in pre-tax gains of $1.3 billion in 2021, pre-tax losses of $1.0 billion in 2020 and pre-tax gains of $192 million in 2019. Berkshire also guarantees debt of other subsidiaries, aggregating approximately $3.8 billion at December 31, 2021. Generally, Berkshire’s guarantee of a subsidiary’s debt obligation is an absolute, unconditional and irrevocable guarantee for the full and prompt payment when due of all payment obligations. Weighted Average December 31, Interest Rate 2021 2020 Railroad, utilities and energy: Berkshire Hathaway Energy Company (“BHE”) and subsidiaries: BHE senior unsecured debt due 2023-2051 4.3% $ 13,003 $ 13,447 Subsidiary and other debt due 2022-2064 4.1% 36,759 36,420 Short-term borrowings 1.4% 2,009 2,286 Burlington Northern Santa Fe (“BNSF”) and subsidiaries due 2022-2097 4.5% 23,219 23,220 $ 74,990 $ 75,373

BHE subsidiary debt represents amounts issued pursuant to separate financing agreements. Substantially all of the assets of certain BHE subsidiaries are, or may be, pledged or encumbered to support or otherwise secure debt. These borrowing arrangements generally contain various covenants, including covenants which pertain to leverage ratios, interest coverage ratios and/or debt service coverage ratios. During 2021, BHE and its subsidiaries issued term debt of approximately $2.2 billion with maturity dates ranging from 2028 to 2052 and a weighted average interest rate of 3.2% and repaid $2.5 billion of term debt.

K-99

Notes to Consolidated Financial Statements (Continued) (18) Notes payable and other borrowings (Continued) BNSF’s borrowings are primarily senior unsecured debentures. During 2021, BNSF issued $1.55 billion of term debt with maturity dates in 2051 and 2052 and a weighted average interest rate of 3.1% and repaid debt of $1.54 billion. As of December 31, 2021, BNSF, BHE and their subsidiaries were in compliance with all applicable debt covenants. Berkshire does not guarantee any debt, borrowings or lines of credit of BNSF, BHE or their subsidiaries. Our subsidiaries had unused lines of credit and commercial paper capacity to support short-term borrowing programs and provide additional liquidity. Unused lines of credit were approximately $10.4 billion at December 31, 2021, which included approximately $8.7 billion related to BHE and its subsidiaries. Debt principal repayments expected during each of the next five years are as follows (in millions). Amounts in 2022 include short-term borrowings. 2022 2023 2024 2025 2026 Insurance and other $ 1,933 $ 5,879 $ 2,154 $ 2,703 $ 3,422 Railroad, utilities and energy 4,206 4,832 3,991 3,792 2,033 $ 6,139 $ 10,711 $ 6,145 $ 6,495 $ 5,455

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 normal 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.

We file income tax returns in the United States 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 U.S. federal income tax returns from 2012 through 2019 remain open, and tax years 2014 through 2019 are under audit. We are also under audit or subject to audit with respect to income taxes in many state and foreign jurisdictions. It is reasonably possible that certain of these income tax examinations will be settled in 2022. We currently do not believe that the outcome of unresolved issues or claims will be material to our Consolidated Financial Statements. At December 31, 2021 and 2020, net unrecognized tax benefits were $1,046 million and $1,113 million, respectively. Included in the balance at December 31, 2021, were $878 million of tax positions that, if recognized, would impact the effective tax rate. The remaining balance in net unrecognized tax benefits principally relates to tax positions where the ultimate recognition is highly certain but there is uncertainty about the timing of recognition. Because of the impact of deferred income tax accounting, these positions, when recognized, would not affect the annual effective income tax rate. Other differences, net included expense of $60 million in 2020 and $377 million in 2019 for uncertain tax positions related to investments by a subsidiary in certain tax equity investment funds that generated income tax benefits from 2015 through 2018. We concluded it was more likely than not those income tax benefits are not valid. We do not expect any material increases to the estimated amount of unrecognized tax benefits during 2022.

Notes to Consolidated Financial Statements (Continued) (20) Fair value measurements (Continued) 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; and inputs 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 with similar 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 is required to use its own assumptions regarding unobservable inputs because there is little, if any, market activity in the assets 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 assets and liabilities measured and carried at fair value on a recurring basis with the use of significant unobservable inputs (Level 3) for each of the three years ending December 31, 2021 follow (in millions).

Notes to Consolidated Financial Statements (Continued) (20) Fair value measurements (Continued) 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 subject to contractual restrictions on transferability and contain provisions that 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 model are observable, we made assumptions regarding the expected duration and volatility of the warrants. (21) Common stock Changes in Berkshire’s issued, treasury and outstanding common stock during the three years ending December 31, 2021 are shown in the table below.

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 not convertible into Class A common stock. On an equivalent Class A common stock basis, there were 1,477,429 shares outstanding as of December 31, 2021 and 1,543,960 shares outstanding as of December 31, 2020. Since we have two classes of common stock, we provide earnings per share data on the Consolidated Statements of Earnings for average equivalent Class A shares outstanding and average equivalent Class B shares outstanding. Class B shares are 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, and Charlie Munger, Vice Chairman of the Board, believe 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.

Notes to Consolidated Financial Statements (Continued) (22) Revenues from contracts with customers We recognize revenue when a good or service is 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. The following tables summarize customer contract revenues disaggregated by reportable segment and the source of the revenue for each of the three years ended December 31, 2021 (in millions). Other revenues, which are not considered to be revenues from contracts with customers under GAAP, are primarily insurance premiums earned, interest, dividend and other investment income and leasing revenues.

The projected benefit obligation (“PBO”) is the actuarial present value of benefits earned based upon service and compensation 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 non-U.S. plans and non-qualified U.S. plans are unfunded and the aggregate PBOs of such plans were $1.4 billion and $1.6 billion as of December 31, 2021 and 2020, respectively. The cost of certain BHE pension plans are expected to be recoverable through the regulated rate making process.

See Note 20 for a discussion of the three levels of fair value measurements. Plan assets are generally invested with the long-term objective of 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 reflect subjective 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.

Several of our subsidiaries also sponsor defined contribution retirement plans, such as 401(k) or profit-sharing plans. Employee contributions are subject to regulatory limitations and the specific plan provisions. Several plans provide for employer matching contributions up to levels specified in the plans and provide for additional discretionary contributions as determined by management. Our defined contribution plan expense was approximately $1.0 billion in 2021, $1.4 billion in 2020 and $1.2 billion in 2019.

Notes to Consolidated Financial Statements (Continued) (25) 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, selling and distribution characteristics, even though those business units are operated under separate local management. 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 related to Berkshire’s business acquisitions or certain 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. Business Identity Business Activity Insurance: GEICO Underwriting private passenger automobile insurance mainly by direct response methods Berkshire Hathaway Primary Group Underwriting multiple lines of property and casualty insurance policies for primarily commercial accounts Berkshire Hathaway Reinsurance Group Underwriting excess-of-loss, quota-share and facultative reinsurance worldwide Railroad (“BNSF”) Operation of one of the largest railroad systems in North America through Burlington Northern Santa Fe LLC Utilities and energy (“BHE”) Regulated electric and gas utility, including power generation and distribution activities and real estate brokerage activities through Berkshire Hathaway Energy Company and affiliates Manufacturing Manufacturers of numerous products including industrial, consumer and building products, including home building and related financial services McLane Company (“McLane”) Wholesale distribution of groceries and non-food items Service and retailing Providers of numerous services including shared aircraft ownership programs, aviation pilot training, electronic components distribution, various retailing businesses, including automobile dealerships and trailer and furniture leasing

Consolidated sales, service and leasing revenues were $151.0 billion in 2021, $132.3 billion in 2020 and $140.8 billion in 2019. Sales, service and leasing revenues attributable to the United States were 85% in 2021, 86% in 2020 and 85% in 2019 of such amounts. The remainder of sales, service and leasing revenues were primarily in Europe, Canada and the Asia Pacific region. Railroad, utilities and energy revenues were $48.1 billion in 2021, $41.8 billion in 2020 and $43.5 billion in 2019. In each of the three years, approximately 96% of such revenues were attributable to the United States. At December 31, 2021, approximately 89% of our consolidated net property, plant and equipment and equipment held for lease was located in the United States with the remainder primarily in Canada and the United Kingdom. (26) 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. 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 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. Our subsidiaries regularly make commitments in the ordinary course of business for the future purchase of goods and services used 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 and our shared aircraft ownership and leasing business. As of December 31, 2021, estimated future payments under those arrangements were as follows: $8 billion in 2022, $4 billion in 2023, $3 billion in 2024, $2 billion in 2025, $2 billion in 2026 and $15 billion after 2026. As indicated in Note 5, we have an agreement to acquire an additional 41.4% ownership interest in Pilot in 2023. At that time, Pilot will become a consolidated subsidiary. Additionally, 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. The timing and the amount of any future payments that might be required to such noncontrolling shareholders are contingent on future actions of the noncontrolling owners and the value of the interest being acquired. If we had acquired the additional interest in Pilot and all outstanding noncontrolling interests as of December 31, 2021, we estimate the aggregate cost of these acquisitions would approximate $11 billion.

BERKSHIRE HATHAWAY INC.

To the Shareholders of Berkshire Hathaway Inc.:

Warren has asked me to provide a summary of Berkshire’s actions related to sustainability within its operating companies. The management of these actions is owned by Berkshire’s exceptional operating CEOs. Under their leadership, and with my support, many of Berkshire’s diverse businesses have developed sustainability frameworks and are independently disclosing environmental initiatives and data, such as greenhouse gas (“GHG”) emissions.

Berkshire Hathaway Energy (“BHE”) and Burlington Northern Santa Fe (“BNSF”) – two of Berkshire’s giants – have long been engaged in delivering sustainable outcomes that benefit all constituencies including customers, communities, state and federal governments and Berkshire’s shareholders. The two businesses generated aggregate net earnings of $10.0 billion in 2021 and their direct GHG emissions represent more than 90% of Berkshire’s direct emissions – a huge margin. Other subsidiaries, of course, are important, but Berkshire will have failed if BHE and BNSF do not achieve their GHG emissions reduction goals.

Here are the annual GHG emissions from these two businesses: Annual GHG Emissions (million metric tons)

2030 Company Baseline 2021 Target

BHE has selected 2005 as its baseline for GHG emissions – a year many others in the utility industry utilize. BHE’s primary source of GHG emissions is the generation of electricity from power plants that are fueled by coal and natural gas. BHE’s utilities work with their regulators to implement state policies that protect the energy and economic needs of its constituents. BHE cannot develop a renewable energy project or retire a coal plant without the support of regulators, who ensure that any action taken by BHE is made in the best interest of customers.

I am pleased to report that BHE’s ability to make significant investments in renewables has created the opportunity to actively reduce coal generation while maintaining reliability and keeping customer costs low in the process.

Specifically, BHE has become a leading force in wind, solar and transmission activity across much of the U.S. BHE, through its Iowa utility MidAmerican Energy, began construction of its first wind turbines in 2004, investing a little over $300 million in these assets. Today, MidAmerican has over 3,400 turbines in operation and has invested $13.6 billion in wind production. This incredible expenditure helps MidAmerican to produce renewable energy equivalent to 88% of its Iowa customers’ annual energy needs. It is attracting new customers too – data center activity is growing exponentially throughout Iowa, driven by MidAmerican’s combination of low cost and clean power. This is not the end of MidAmerican’s journey – just last month, the company announced plans for a new $3.9 billion wind and solar project, which will enable renewable generation in excess of its customers’ annual usage in Iowa by 2025.

The commitment to renewables goes beyond Iowa. In addition to the $13.6 billion invested in wind at MidAmerican, BHE has invested $16.5 billion in other wind, solar and geothermal energy projects that it operates and has financed an additional $6.9 billion for other operators.

A-3

While making these significant investments in renewables, BHE has retired 16 of its coal generation units. Looking ahead, BHE plans to retire an additional 16 coal units between 2022 and 2030 in a reliable and cost-effective manner for its customers, thereby achieving its 50% GHG emissions reduction target for 2030. Progress has been consistent with this objective. Simultaneously, BHE plans to invest billions of dollars in wind, solar and storage capacity, as well as invest in new transmission lines in the West – a story told in Berkshire’s 2020 annual report. These transmission lines connect remote noncarbon resources to far-away population centers. As additional noncarbon generation is deployed and transmission is expanded, BHE plans to retire all remaining coal units by 2049 and all natural gas units by 2050, enabling it to achieve net zero GHG emissions. BHE routinely communicates in detail its approach to decarbonization, outlining its strategies and the capital it will deploy to achieve this objective. BHE’s regulated U.S. utilities issue third-party debt as part of their capital structure. Consequently, BHE has made environmental disclosures every year for the past 15 years through investor presentations. These documents are publicly available on BHE’s website. BNSF has selected 2018 as its GHG emissions baseline year, which is consistent with its largest peer in the West. BNSF’s GHG emissions profile is comprised of the consumption of diesel fuel in its locomotives (accounting for 80% of its baseline GHG emissions), the third-party production and transportation of those fuels and, to a lesser extent, the consumption of natural gas and electricity across its broader operations. BNSF is a common carrier railroad with a federal legal obligation to transport any commodity – including coal and hazardous materials – upon its customers’ request. Yet, the environmental impacts of the transportation of these goods are reduced thanks to BNSF’s focus on safety and efficiency. By nature, rail is the most environmentally efficient mode of land-based transportation, moving its customers’ products more than three times as far as trucks on a per ton mile basis. To build on this, BNSF has committed to and embraced a broader sustainability model, applying a science-based approach that will provide a 30% reduction in BNSF’s GHG emissions by 2030 as measured from its baseline. Progress has been consistent with this objective. More will follow. Berkshire’s railroad will continue its improvements in fuel efficiency and increase its utilization of renewable diesel fuel. Long-term solutions, such as battery-electric and hydrogen locomotives, are also being evaluated and field tested. When successful, these measures will lower BNSF’s GHG emissions and increase its cost competitiveness. Sustainability is fundamental to BNSF’s value proposition. BHE and BNSF are not alone when it comes to these sustainability endeavors at Berkshire. Many subsidiaries have also been responding to their customers’ varied needs by carrying out commitments to sustainable outcomes and communicating environmental information. Equally, these efforts make good business sense. For example, many consumers are interested in improved environmental outcomes for apparel products. As a result, three of Berkshire’s manufacturing businesses that specialize in these products – Fruit of the Loom, Brooks Sports and Garan – each disclose the environmental impacts of the products they sell and their plans to reduce those impacts long term. Further, all three businesses have committed to 2030 GHG emissions reduction targets, consistent with the expectations of each customer base. This information can be found on their websites. Additionally, four manufacturing businesses across Berkshire’s industrial and building products groups – Lubrizol, Johns Manville, Acme Brick and Shaw Industries – disclose on their websites recent GHG emissions data and other sustainability information that is most relevant to their customers and operations. Berkshire’s culture is strong, and its operating managers daily demonstrate ownership and accountability by being responsive to the needs of their customers. The managers of these subsidiaries will continue to own all business decisions, including their approach to sustainability and related environmental outcomes. Berkshire’s businesses are exceptionally well positioned to deliver on ever-changing customer expectations regarding sustainability, in both resources and attitude, while also driving value for Berkshire’s shareholders. I am supportive of these outlined objectives and fully committed to Berkshire’s ongoing journey of delivering sustainable solutions.

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 and pay 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 to others. Meanwhile, insurers get to invest this float for their own benefit. Though individual policies and claims come and go, the amount of float an insurer holds usually remains fairly stable in relation to premium volume. Consequently, as our business grows, so does our float. And how it has grown, as the following table shows: Year Float (in millions) 1970 ............................................................ $ 39 1980 ............................................................ 237 1990 ............................................................ 1,632 2000 ............................................................ 27,871 2010 ............................................................ 65,832 2018 ............................................................ 122,732 2019 ............................................................ 129,423 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 on each dollar of float, they now take in only 2 cents or 3 cents (or even less if their operations are concentrated in countries mired in the never-never land of negative rates). 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 16 of the last 17 years, the exception being 2017, when our pre-tax loss was a whopping $3.2 billion. For the entire 17-year span, our pre-tax gain totaled $27.5 billion, of which $400 million was recorded in 2019. That record is no accident: Disciplined risk evaluation is the daily focus of our insurance managers, who know that the rewards of 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: We will most certainly not have an underwriting profit in 16 of the next 17 years. 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 Michael 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 and they 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.
