BERKSHIRE HATHAWAY INC

June 30, 2024

Note 1. General

The accompanying unaudited Consolidated Financial Statements include the accounts of Berkshire Hathaway Inc. (“Berkshire” or “Company”) consolidated with the accounts of all its subsidiaries and affiliates in which Berkshire holds controlling financial interests as of the financial statement date. In these notes, the terms “us,” “we” or “our” refer to Berkshire and its consolidated subsidiaries. Reference is made to Berkshire’s most recently issued Annual Report on Form 10-K (“Annual Report”), which includes information necessary or useful to understanding Berkshire’s businesses and financial statement presentations. Our significant accounting policies and practices were presented as Note 1 to the Consolidated Financial Statements included in the Annual Report.

Financial information in this Quarterly Report reflects all adjustments that are, in the opinion of management, necessary to a fair statement of results for the interim periods in accordance with accounting principles generally accepted in the United States (“GAAP”). For several reasons, our results for interim periods may not be indicative of results to be expected for the year. The timing and magnitude of catastrophe losses incurred by insurance subsidiaries and the estimation error inherent to the process of determining liabilities for unpaid losses of insurance subsidiaries can be more significant to results of interim periods than to results for a full year. Given the size of our equity security investment portfolio, changes in market prices and the related changes in unrealized gains and losses on equity securities will produce significant volatility in our interim and annual earnings. In addition, gains and losses from the periodic revaluation of certain assets and liabilities denominated in foreign currencies and asset impairment charges may cause significant variations in periodic net earnings.

Significant estimates are used in the preparation of our Consolidated 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 estimation of certain losses assumed under insurance and reinsurance contracts. These estimates may be subject to significant adjustments in future periods due to ongoing macroeconomic and geopolitical events, as well as changes in industry or company-specific factors or events.

Note 2. New accounting pronouncements

In March 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2023-02, “Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method” (“ASU 2023-02”). ASU 2023-02 permits reporting entities to elect to account for tax equity investments from which the income tax credits are received using the proportional amortization method at the program level if certain conditions are met. We elected to apply the proportional accounting method to eligible affordable housing tax credit investments using the modified retrospective method. We recorded a charge to retained earnings of $127 million, representing the cumulative effect of applying the proportional method to these investments as of January 1, 2024.

In November 2023, the FASB issued Accounting Standards Update 2023-07, “Improvements to Reportable Segment Disclosures” (“ASU 2023-07”), which requires disclosures of significant expenses by segment and interim disclosure of certain items that were previously required only on an annual basis. ASU 2023-07 is to be applied on a retrospective basis and is effective for our 2024 annual Consolidated Financial Statements and interim periods beginning in 2025.

In December 2023, the FASB issued Accounting Standards Update 2023-09, “Improvements to Income Tax Disclosures” (“ASU 2023-09”), which provides for additional income tax rate reconciliation and income taxes paid disclosures. ASU 2023-09 may be adopted on a prospective or retrospective basis and is effective for fiscal years beginning after December 15, 2024, with early adoption permitted.

On March 6, 2024, the U.S. Securities Exchange Commission (“SEC”) issued Release No. 33-11275 and No. 34-99678 “The Enhancement and Standardization of Climate-Related Disclosures for Investors” (“Climate Disclosure Rules”). Among its provisions, the Climate Disclosure Rules will require certain disclosures related to severe weather events and other natural conditions, and other disclosures about climate-related risks that materially impacted or are reasonably likely to materially impact the business strategy, results of operations or financial condition of the registrant. The Climate Disclosure Rules are currently effective for large-accelerated SEC filers in annual reports for years beginning on or after January 1, 2025. However, on April 4, 2024, the SEC stayed implementation of the Climate Disclosure Rules, pending the completion of judicial review.

We are evaluating the impacts ASUs 2023-07 and 2023-09 and the Climate Disclosure Rules will have on disclosures in our Consolidated Financial Statements.

Note 3. Significant business acquisitions

Our long-held acquisition strategy is to acquire businesses that have consistent earning power, good returns on equity and able and honest management. Financial results attributable to business acquisitions are included in our Consolidated Financial Statements beginning on their respective acquisition dates.

On January 31, 2023, we acquired an additional 41.4% interest in Pilot Travel Centers, LLC (“Pilot”) for approximately $8.2 billion. The acquisition increased our interest to 80%, representing a controlling interest in Pilot for financial reporting purposes as of that date. Accordingly, we began consolidating Pilot’s financial statements in our Consolidated Financial Statements on February 1, 2023. Prior to that date, we accounted for our 38.6% interest in Pilot under the equity method.

Pilot operates more than 650 travel center and 75 fuel-only locations across 44 U.S. states andfive Canadian provinces, primarily under the names Pilot or Flying J, as well as large wholesale fuel and fuel marketing businesses in the U.S. Pilot also sells diesel fuel at other locations in the U.S. and Canada through various arrangements with third party travel centers and operates a water disposal business in the oil fields sector. Since Pilot’s most significant business activities involve purchasing and selling fuel (energy) on a wholesale and retail basis, and other energy-related businesses, we include Pilot within the railroad, utilities and energy sections of our Consolidated Balance Sheets and Consolidated Statements of Earnings.

In applying the acquisition method of accounting, we remeasured our previously held 38.6% investment in Pilot to fair value as of the acquisition date. We recognized a one-time, non-cash remeasurement gain of approximately $3.0 billion in the first quarter of 2023, representing the excess of the fair value of that interest over the carrying value under the equity method.

In January 2024, we acquired the remaining noncontrolling interests in Pilot for $2.6 billion, increasing our ownership of Pilot to 100%. The acquisition of a noncontrolling interest represents an equity transaction and we recorded an increase of $517 million to capital in excess of par for the excess of the carrying value of the noncontrolling interest acquired over the consideration paid, net of deferred income tax liabilities arising from the transaction.

A summary of the values of Pilot’s assets acquired, liabilities assumed and noncontrolling interestsas of January 31, 2023 follows (in millions).

*Goodwill from this acquisition is expected to be deductible for income tax purposes.

Note 4. Investments in fixed maturity securities

Investments in fixed maturity securities are summarized as follows (in millions).

Note 4. Investments in fixed maturity securities

As of June 30, 2024, approximately 94% of ourforeign 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 June 30, 2024 are summarized below by contractual maturity dates (in millions). Actual maturities may differ from contractual maturities due to prepayment rights held by issuers.

Note 5. Investments in equity securities

Investments in equity securities are summarized as follows (in millions).

*Approximately 72% of the aggregate fair value was concentrated infive companies (American Express Company – $35.1 billion; Apple Inc. – $84.2 billion; Bank of America Corporation – $41.1 billion; The Coca-Cola Company – $25.5 billion and Chevron Corporation – $18.6 billion).

*Approximately 79% of the aggregate fair value was concentrated infive companies (American Express Company – $28.4 billion; Apple Inc. – $174.3 billion; Bank of America Corporation – $34.8 billion; The Coca-Cola Company – $23.6 billion and Chevron Corporation – $18.8 billion).

In 2019, we invested $10 billion in non-voting Cumulative Perpetual Preferred Stock of Occidental Petroleum Corporation (“Occidental”) and in Occidental common stock warrants. During 2022, we began acquiring common stock of Occidental. Our aggregate voting interest in Occidental common stock exceeded 20% on August 4, 2022, and we adopted the equity method as of that date. See Note 6. Our investments in the Occidental preferred stock and Occidental common stock warrants are recorded at fair value within Commercial, industrial and other in the tables above. Such investments are not in-substance common stock under GAAP and are not eligible for the equity method.

The Occidental preferred stock accrues dividends at 8% per annum and is redeemable at the option of Occidental commencing in 2029 at a redemption price equal to 105% of the liquidation value, plus any accumulated and unpaid dividends. As of June 30, 2024, our investment in Occidental preferred stock had an aggregate liquidation value of approximately $8.5 billion, which reflected mandatory redemptions by Occidental during 2023 of approximately $1.5 billion. The Occidental common stock warrants allow us to purchase up to 83.86 million shares of Occidental common stock at an exercise price of $59.62 per share. The warrants are exercisable in whole or in part untilone year after the date the preferred stock is fully redeemed.

On June 30, 2024, we owned 151.6 million shares of American Express Company (“American Express”) common stock representing 21.3% of its outstanding common stock. Since 1995, we have been party to an agreement with American Express whereby we agreed to vote a significant portion of our shares in accordance with the recommendations of the American Express Board of Directors. We have also agreed to passivity commitments as requested by the Board of Governors of the Federal Reserve System, which collectively, in our judgment, restrict our ability to exercise significant influence over the operating and financial policies of American Express. Accordingly, we do not use the equity method with respect to our investment in American Express common stock, and we continue to record our investment at fair value.

Note 6. Equity method investments

Berkshire and its subsidiaries hold investments in certain businesses that are accounted for pursuant to the equity method. Currently, the most significant of these are our investments in the common stock of The Kraft Heinz Company (“Kraft Heinz”) and Occidental. As of June 30, 2024, we owned 26.9% of the outstanding Kraft Heinz common stock and 28.8% of the outstanding Occidental common stock, which excludes the potential effect of the exercise of the Occidental common stock warrants.

Kraft Heinz manufactures and markets food and beverage products, including condiments and sauces, cheese and dairy, meals, meats, refreshment beverages, coffee and other grocery products. Occidental is an international energy company, whose activities include oil and natural gas exploration, development and production and chemicals manufacturing businesses. Occidental’s financial information is not available in time for concurrent reporting in our Consolidated Financial Statements. Therefore, we report the equity method effects for Occidental on a one-quarter lag.

Kraft Heinz and Occidental common stocks are publicly traded. The fair values and our carrying values of these investments are included in the following table (in millions).

As of June 30, 2024, the excess of the carrying values over the fair values of our investments in Kraft Heinz and Occidental was 20% and 2%, respectively, of the carrying values of each investment. We evaluated these investments for other-than-temporary impairment as of June 30, 2024. We considered our ability and intent to hold the investment until the fair value exceeds carrying value, the magnitude and duration of the decline in fair value, the operating results of the company, as well as other factors. Based on the prevailing facts and circumstances, we concluded the recognition of an impairment charge in earnings was not required.

We also own a 50% interest in Berkadia Commercial Mortgage LLC (“Berkadia”), which is accounted for under the equity method and is included in other in the preceding table. Jefferies Financial Group Inc. (“Jefferies”) owns the other 50% interest. Berkadia engages in mortgage banking, investment sales and servicing of commercial/multi-family real estate loans. Berkadia’s commercial paper borrowing capacity (currently limited to $1.5 billion) is supported by a surety policy issued by a Berkshire insurance subsidiary. Jefferies is obligated to indemnify us for one-half of any losses incurred under the policy.

As of June 30, 2024, the carrying values of our investments in Kraft Heinz and Berkadia approximated our share of shareowners’ equity of each of these entities. The carrying value of our investment in Occidental common stock exceeded our share of its shareholders’ equity as of March 31, 2024 by approximately $10 billion. Based upon the limited information available to us, we concluded the excess represents goodwill.

Our earnings and distributions received from equity method investments are summarized in the following table (in millions). As previously described, on February 1, 2023, we ceased accounting for Pilot under the equity method. Equity method earnings attributable to Pilot were $105 million for the month ending January 31, 2023. The earnings we recorded in the first six months of 2024 and 2023 for Occidental represented our share of its earnings for the six months ending March 31, 2024 and 2023, respectively.

Note 6. Equity method investments

Summarized consolidated financial information of Kraft Heinz follows (in millions).

Summarized consolidated financial information of Occidental follows (in millions).

Note 7. Investment gains (losses)

Investment gains (losses) in the second quarter and first six months of 2024 and 2023 are summarized as follows (in millions).

Equity securities gains and losses include unrealized gains and losses from changes in fair values during the period on equity securities we still own, as well as gains and losses on securities we sold during the period. Our proceeds from sales of equity securities were approximately $97.1 billion in the first six months of 2024 and $25.8 billion in 2023. In the preceding table, investment gains and losses on equity securities sold during the period represent the difference between the sales proceeds and the fair value of the equity securities sold at the beginning of the applicable period or, if later, the acquisition date. Taxable gains and losses on equity securities sold are generally the difference between the proceeds from sales and cost. Our sales of equity securities produced taxable gains of $59.6 billion in the second quarter and $73.7 billion in the first six months of 2024 compared to taxable gains of $2.4 billion in the second quarter and $4.6 billion in the first six months of 2023. Other investment gains in the first six months of 2023 included a non-cash gain of approximately $3.0 billion from the remeasurement of our pre-existing 38.6% interest in Pilot through the application of acquisition accounting under GAAP.

Note 8. Loans and finance receivables

Loans and finance receivables are summarized as follows (in millions).

Loans and finance receivables are principally manufactured home loans, and to a lesser extent, commercial loans and site-built home loans. Reconciliations of the allowance for credit losses on loans and finance receivables for the first six months of 2024 and 2023 follow (in millions).

As of June 30, 2024, substantially all manufactured and site-built home loans were evaluated collectively for impairment, and we considered approximately 96% of these loans to be current as to payment status. A summary of performing and non-performing home loans before discounts and allowances by year of loan origination as of June 30, 2024 follows (in millions).

We also hold a limited number of commercial loans originated or acquired several years ago. The aggregate carrying value of these loans approximated$725 million at June 30, 2024 and $850 million at December 31, 2023. The loans are generally secured by real estate properties or by other assets and are individually evaluated for expected credit losses.

Note 9. Other receivables

Other receivables are comprised of the following (in millions).

Aggregate provisions for credit losses in the first six months with respect to receivables in the preceding table were $233 million in 2024 and $278 million in 2023. Charge-offs, net of recoveries, in the first six months were $230 million in 2024 and $280 million in 2023.

Note 10. Inventories

Inventories of our insurance and other businesses are comprised of the following (in millions).

Inventories, materials and supplies of our railroad, utilities and energy businesses are included in other assets and were approximately $4.3 billion at June 30, 2024 and $4.2 billion as of December 31, 2023.

Note 11. Property, plant and equipment

A summary of property, plant and equipment of our insurance and other businesses follows (in millions).

A summary of property, plant and equipment of our railroad and utilities and energy businesses follows (in millions). The utility generation, transmission and distribution systems and interstate natural gas pipeline assets are owned by regulated public utility and natural gas pipeline subsidiaries.

Depreciation expense for the first six months of 2024 and 2023 is summarized below (in millions).

Note 12. Equipment held for lease

Equipment held for lease includes railcars, aircraft and other equipment, including over-the-road trailers, intermodal tank containers, cranes, storage units and furniture. Equipment held for lease is summarized below (in millions).

Depreciation expense for equipment held for lease in the first six months was $695 million in 2024 and $623 million in 2023. Fixed and variable operating lease revenues for the second quarter and first six months of 2024 and 2023 are summarized below (in millions).

Note 13. Goodwill and other intangible assets

Reconciliations of the changes in the carrying value of goodwill for the first six months of 2024 and for the year ended December 31, 2023 follow (in millions).

*Net of accumulated goodwill impairm ents of $11.1 billion as of June 30, 2024 and December 31, 2023.

Other intangible assets are summarized below (in millions).

Other intangible assets of the railroad, utilities and energy businesses are included in other assets. Intangible asset amortization expense in the first six months was $892 million in 2024 and $872 million in 2023. Intangible assets with indefinite lives were $18.9 billion as of June 30, 2024 and December 31, 2023 and primarily related to certain customer relationships and trademarks and trade names.

Note 14. Unpaid losses and loss adjustment expenses

Reconciliations of the changes in unpaid losses and loss adjustment expenses (“claim liabilities”), excluding liabilities under retroactive reinsurance contracts (see Note 15), for each of the six-month periods ended June 30, 2024 and 2023 follow (in millions).

Our 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. Incurred losses and loss adjustment expenses 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.

We recorded net reductions of estimated ultimate liabilities for prior accident years of $1.2 billion in the first six months of 2024 and $1.9 billion in 2023, 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 1.1% in 2024 and 1.9% in 2023.

Ultimate liabilities for prior accident years of primary insurance businesses in the first six months were reduced $433 million in 2024 and $1.1 billion in 2023, primarily attributable to lower than expected private passenger auto and medical professional liability losses. In the first six months, ultimate liabilities for prior accident years of property and casualty reinsurance businesses were reduced $734 million in 2024, primarily attributable to lower than expected property losses, and $883 million in 2023, from lower than expected property and casualty losses.

Note 15. 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 and may include significant levels of asbestos, environmental and other mass tort claims. Retroactive reinsurance contracts are generally subject to aggregate policy limits and thus, our exposure to such claims under these contracts is likewise limited. Reconciliations of the changes in estimated liabilities for retroactive reinsurance unpaid losses and loss adjustment expenses for each of the six-month periods ended June 30, 2024 and 2023 follow (in millions).

In the preceding table, the classification of incurred losses and loss adjustment expenses is based on the inception dates of the contracts, which reflect when our exposure to losses began. Incurred losses and loss adjustment expenses in the Consolidated Statements of Earnings include changes in estimated liabilities and related deferred charge asset amortization and adjustments arising from the changes in estimated timing and amount of future loss payments. Unamortized deferred charges on retroactive reinsurance contracts were $9.1 billion at June 30, 2024 and $9.5 billion at December 31, 2023.

A summary of our long-duration life, annuity and health insurance benefits liabilities as of June 30, 2024 and 2023, disaggregated for our two primary product categories, periodic payment annuity and life and health insurance, follows. Other liabilities include incurred-but-not reported claims and claims in the course of settlement. Amounts are in millions.

Reconciliations of periodic payment annuity and life and health insurance benefits liabilities for the first six months of 2024 and 2023 follow (in millions). The information reflects the changes in discounted present values of expected future policy benefits and expected future net premiums before reinsurance ceded. Net premiums represent the portion of expected gross premiums that are required to provide for future policy benefits and variable expenses.

Liabilities for future life and health policy benefits and reinsurance recoverables declined in the first six months of 2024, primarily attributable to the commutations of certain life reinsurance contracts. The impacts of these contract commutations on expected future policy benefits and future net premiums were reflected in effects of actual versus expected experience.

Other information relating to our long-duration insurance liabilities as of June 30, 2024 and 2023 follows (dollars in millions).

Gross premiums earned and interest expense before reinsurance ceded for the first six months of 2024 and 2023 were as follows (in millions).

Note 17. Notes payable and other borrowings

Notes payable and other borrowings of our insurance and other businesses are summarized below (dollars in millions). The weighted average interest rates and maturity date ranges are based on borrowings as of June 30, 2024.

Note 17. Notes payable and other borrowings

Berkshire parent company borrowings consist of senior unsecured debt. In the first six months of 2024, Berkshire repaid approximately $1.1 billion of maturing senior notes. In April 2024, Berkshire issued ¥263.3 billion (approximately $1.7 billion) of senior notes with interest rates ranging from 0.974% to 2.498% and maturity dates ranging from 2027 to 2054.

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. Berkshire also guarantees certain debt of other subsidiaries, aggregating approximately $2.7 billion at June 30, 2024. 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.

The carrying values of Berkshire and BHFC non-U.S. Dollar denominated senior notes (€5.85 billion, £1.75 billion and ¥1,522 billion par at June 30, 2024) reflect the applicable exchange rates as of each balance sheet date. 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 produced pre-tax gains of $588 million in the second quarter and $1.4 billion in the first six months of 2024 and $555 million in the second quarter and $529 million in the first six months of 2023.

Notes payable and other borrowings of our railroad, utilities and energy businesses are summarized below (dollars in millions). The weighted average interest rates and maturity date ranges are based on borrowings as of June 30, 2024.

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 such debt. These borrowing arrangements generally contain various covenants, including covenants which pertain to leverage ratios, interest coverage ratios and/or debt service coverage ratios. In the first six months of 2024, BHE subsidiaries issued $5.4 billion of term debt with a weighted average interest rate of 5.4% and maturity dates ranging from 2029 to 2055 and BHE and its subsidiaries repaid term debt and short-term borrowings aggregating approximately $4.0 billion.

As of December 31, 2023, Pilot’s borrowings primarily represented secured syndicated loans. In March, 2024, certain Berkshire insurance subsidiaries loaned $5.7 billion to Pilot, which Pilot used to prepay its then outstanding third-party borrowings. BNSF’s borrowings are primarily senior unsecured debentures. In the second quarter of 2024, BNSF issued $1.3 billion of 5.5% debentures due in 2055 and repaid $500 million of maturing debentures. As of June 30, 2024, BHE, BNSF and their subsidiaries were in compliance with all applicable debt covenants. Berkshire does not guarantee any debt, borrowings or lines of credit of BHE, BNSF or their subsidiaries.

Unused lines of credit and commercial paper capacity to support operations and provide additional liquidity for our subsidiaries were approximately $11.3 billion at June 30, 2024, of which approximately $10.1 billion related to BHE and its subsidiaries.

Note 18. Fair value measurements

Our financial assets and liabilities are summarized below, with fair values shown according to the fair value hierarchy (in millions). The carrying values of cash and cash equivalents, U.S. Treasury Bills, other receivables and accounts payable, accruals and other liabilities are considered to be reasonable estimates of or otherwise approximate the fair values.

(1)

Assets are included in other assets and liabilities are included in accounts payable, accruals and other liabilities.

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.

Note 18. Fair value measurements

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 significant assets and liabilities measured and carried at fair value on a recurring basis with the use of significant unobservable inputs (Level 3) for the six months ended June 30, 2024 and 2023 follow (in millions).

Quantitative information as of June 30, 2024 for the significant assets and liabilities measured and carried at fair value on a recurring basis with the use of significant unobservable inputs (Level 3) follows (dollars in millions).

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

Note 19. Common stock

Changes in Berkshire’s issued, treasury and outstanding common stock during the first six months of 2024 are shown in the table below. In addition to our common stock,1,000,000 shares of preferred stock are authorized, butnone are issued.

Each Class A common share is entitled toone vote per share. Class B common stock possesses dividend and distribution rights equal toone-fifteen-hundredth (1/1,500) of such rights of Class A common stock. Each Class B common share possesses voting rights equal toone-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 1,436,696 shares outstanding as of June 30, 2024 and 1,441,483 shares outstanding as of December 31, 2023.

Note 19. Common stock

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 the average Class A shares outstanding.

Berkshire’s common stock repurchase program permits Berkshire to repurchase its shares any time that Warren Buffett, Berkshire’s Chairman of the Board and Chief Executive Officer, believes that the repurchase price is below Berkshire’s intrinsic value, conservatively determined. The program continues to allow share repurchases in the open market or through privately negotiated transactions and does not specify a maximum number of shares to be repurchased. However, repurchases will not be made if they would reduce the 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.

Note 20. Income taxes

Our consolidated effective income tax rates were 20.0% in the second quarter and 19.5% in the first six months of 2024 compared to 20.3% in the second quarter and 20.2% in the first six months of 2023. Our effective income tax rate normally reflects recurring benefits from dividends-received deductions applicable to investments in certain equity securities and production tax credits related to wind-powered electricity generation placed in service in the U.S. Our periodic effective income tax rate will also vary due to the changes in mix of pre-tax earnings, including realized and unrealized investment gains or losses with respect to our investments in equity securities, the amount of non-deductible goodwill impairment charges and other expenses and the underlying income tax rates applicable in the various taxing jurisdictions.

On August 16, 2022, the Inflation Reduction Act of 2022 (“the 2022 Act”) was signed into law. The 2022 Act contains numerous provisions, including a 15% corporate alternative minimum income tax (“CAMT”) on “adjusted financial statement income,” expanded tax credits for clean energy incentives and a 1% excise tax on corporate stock repurchases. The provisions of the 2022 Act are effective for tax years beginning after December 31, 2022. The extent to which the Company incurs CAMT will depend on the facts and circumstances of the given tax year. We do not expect to incur a CAMT liability in 2024. The Internal Revenue Service and the U.S. Department of Treasury may release additional guidance in the future. We will continue to evaluate the impact of the 2022 Act as more guidance becomes available.

The Organization for Economic Co-operation and Development has issued Pillar Two model rules introducing a new global minimum tax of 15% intended to be effective on January 1, 2024. While the U.S. has not yet adopted the Pillar Two rules, various other governments around the world are enacting legislation. As currently designed, Pillar Two will ultimately apply to our worldwide operations. Considering we do not have material operations in jurisdictions with income tax rates lower than the Pillar Two minimum, these rules are not expected to materially increase our global tax costs. There remains uncertainty as to the final Pillar Two model rules. We will continue to monitor U.S. and global legislative action related to Pillar Two for potential impacts.

We are parties in a variety of legal actions that routinely arise out of the normal course of business, including legal actions seeking to establish liability directly through insurance contracts or indirectly through reinsurance contracts issued by Berkshire subsidiaries. Plaintiffs occasionally seek punitive or exemplary damages. We do not believe that such normal and routine litigation will have a material effect on our financial condition or results of operations.

PacifiCorp, a wholly-owned subsidiary of Berkshire’s 92% owned subsidiary, Berkshire Hathaway Energy Company (“BHE”), operates as a regulated electric utility in Oregon and other Western states. HomeServices of America, Inc. is a wholly-owned subsidiary of BHE. Certain legal matters related to these entities are described below.

PacifiCorp

In September 2020, a severe weather event resulting in high winds, low humidity and warm temperatures, contributed to several major wildfires, which resulted in real and personal property and natural resource damage, personal injuries and loss of life and widespread power outages in Oregon and Northern California. These wildfires spread across certain parts of PacifiCorp’s service territory and surrounding areas across multiple counties in Oregon and California, including Siskiyou County, California; Jackson County, Oregon; Douglas County, Oregon; Marion County, Oregon; Lincoln County, Oregon; and Klamath County, Oregon, burning over 500,000 acres in aggregate. Third-party reports for these wildfires (the “2020 Wildfires”) indicate over 2,000 structures destroyed, including residences; several other structures damaged; multiple individuals injured; and several fatalities.

According to the California Department of Forestry and Fire Protection, a wildfire began on July 29, 2022, in the Oak Knoll Ranger District of the Klamath National Forest in Siskiyou County, California located in PacifiCorp’s service territory (the “2022 Wildfire”) burning over 60,000 acres. Third-party reports indicate that the 2022 Wildfire resulted in 11 structures damaged,185 structures destroyed,12 injuries andfour fatalities. The 2020 Wildfires and 2022 Wildfire, together, are referred to as the “Wildfires”.

Investigations into the cause and origin of each of the Wildfires are complex and ongoing and have been or are being conducted by various entities, including the U.S. Forest Service, the California Public Utilities Commission, the Oregon Department of Forestry, the Oregon Department of Justice, PacifiCorp and various experts engaged by PacifiCorp.

As of the date of this filing, a significant number of complaints and demands alleging similar claims related to the Wildfires have been filed in Oregon and California, including a class action complaint in Oregon associated with the 2020 Wildfires for which certain jury verdicts were issued as described below. The plaintiffs seek damages for economic losses, noneconomic losses, including mental suffering, emotional distress, personal injury and loss of life, as well as punitive damages, other damages and attorneys’ fees. Several insurance carriers have filed subrogation complaints in Oregon and California with allegations similar to those made in the aforementioned complaints. Additionally, the U.S. and Oregon Departments of Justice have informed PacifiCorp that they are contemplating filing actions against PacifiCorp in connection with certain of the Oregon 2020 Wildfires. PacifiCorp is actively cooperating with the U.S. and Oregon Departments of Justice on resolving these alleged claims through alternative dispute resolution.

As of June 30, 2024, amounts sought in outstanding complaints and demands filed in Oregon and in certain demands in California approximated $3 billion, excluding any doubling or trebling of damages included in the complaints and the mass complaints described below that seek $43 billion. Generally, the complaints filed in California do not specify damages sought and are excluded from this amount.

Based on available information to date, we believe it is probable that losses will be incurred associated with the Wildfires. Final determinations of liability will only be made following the completion of comprehensive investigations, litigation and similar processes.

On September 30, 2020, a class action complaint against PacifiCorp was filed captioned Jeanyne James et al. v. PacifiCorp et al. (the “James case”), in Oregon Circuit Court in Multnomah County, Oregon (the “Multnomah Court”) in connection with the 2020 Wildfires. In April 2023, a jury trial for the James case with respect to 17 named plaintiffs began in Multnomah Court. In June 2023, the jury issued its verdict finding PacifiCorp liable to the 17 named plaintiffs and to the class with respect tofour wildfires. The jury found PacifiCorp’s conduct grossly negligent, reckless and willful as to each plaintiff and the entire class. The jury awarded the 17 named plaintiffs $90 million of damages, including $4 million of economic damages, $68 million of noneconomic damages and $18 million of punitive damages based on a 0.25 multiplier of the economic and noneconomic damages.

In September 2023, the Multnomah Court ordered trial dates forthree damages phase trials for the James case, wherein plaintiffs in each of thethree damages phase trials would present evidence regarding their damages.

In January 2024, the Multnomah Court entered a limited judgment and money award for the June 2023 James case verdict of $92 million based on the amounts awarded by the jury, as well as doubling of the economic damages and offsetting of insurance proceeds received by plaintiffs. In January 2024, PacifiCorp filed a notice of appeal associated with the June 2023 verdict in the James case, including whether the case can proceed as a class action, and filed a motion to stay further damages phase trials. On February 14, 2024, the Oregon Court of Appeals denied PacifiCorp’s request to stay the damages phase trials. On February 13, 2024, the 17 named plaintiffs filed a notice of cross-appeal as to the January 2024 limited judgment and money award. The appeals process and further actions could take several years.

In January 2024, the jury for the first James case damages phase trial awarded nine plaintiffs $62 million of damages, including $6 million of economic damages and $56 million of noneconomic damages. Subsequently, the Multnomah Court increased the economic damages by $6 million and added $16 million of punitive damages, bringing the aggregate damages awarded to $84 million. In March 2024, the Multnomah Court granted in large part PacifiCorp’s request to offset the damage awards by deducting insurance proceeds received by any of the nine plaintiffs. In April 2024, the Multnomah Court entered a limited judgment and money award of $80 million for the January 2024 James verdict, based on the aggregate damages awarded, offset by insurance proceeds received by plaintiffs.

In March 2024, the jury for the second James case damages phase trial awardedten plaintiffs $42 million of damages, including $12 million of doubled economic damages and $30 million of noneconomic and punitive damages. In May 2024, the Multnomah Court granted PacifiCorp’s request to offset the damage awards by deducting insurance proceeds received by any of theten plaintiffs. In June 2024, the Multnomah Court entered a limited judgment and money award of $38 million for the March 2024 James verdict, based on the aggregate amounts awarded, offset by insurance proceeds received by plaintiffs.

The January, April and June 2024 limited judgments created liens against PacifiCorp, attaching a debt for the money awards. In each instance, PacifiCorp posted a supersedeas bond, which stays any effort to seek payment of the judgment pending final resolution of any appeals. Under ORS 82.010, interest at a rate of 9% per annum will accrue on the judgment commencing at the date the judgment was entered until the entire money award is paid, amended or reversed by an appellate court. PacifiCorp amended its January 2024 appeal of the June 2023 James verdict to include the January 2024 jury verdict and further amended its appeal of the June 2023 verdict to include the March 2024 jury verdict. In March 2024, settlement was reached with five commercial timber plaintiffs in the James case, and the jury trial scheduled for April 2024 was cancelled.

In April, May and July 2024, four separate mass complaints against PacifiCorp naming 1,443 individual class members were filed in the Multnomah Court referencing the James case as the lead case. These mass complaints make allegations seeking economic, noneconomic and punitive damages, as well as doubling of economic damages. PacifiCorp believes the magnitude of damages sought by the class members in the James case mass complaints to be of remote likelihood of being awarded based on the amounts awarded in the jury verdicts described above that are being appealed.

A provision for a loss contingency is recorded when it is probable a liability has been incurred and the amount of loss can be reasonably estimated. PacifiCorp evaluates the related range of reasonably estimated losses and records a loss based on its best estimate within that range or the lower end of the range if there is no better estimate.

Estimated probable losses associated with the Wildfires were based on the information available to the date of this filing, including (i) ongoing cause and origin investigations; (ii) ongoing settlement and mediation discussions; (iii) other litigation matters and upcoming legal proceedings; and (iv) the status of the James case. Wildfire estimated losses include estimates for fire suppression costs, real and personal property damages, natural resource damages and noneconomic damages such as personal injury damages and loss of life damages that are considered probable of being incurred and that it is able to reasonably estimate at this time, and which is subject to change as additional relevant information becomes available.

Through June 30, 2024, PacifiCorp recorded cumulative estimated probable Wildfire losses, before taxes and expected related insurance recoveries, of approximately $2.7 billion, of which $251 million was recorded in the first six months of 2024 and $541 million was recorded in the first six months of 2023. Expected insurance recoveries recorded to date in connection with the Wildfires are $534 million, including $133 million in the first six months of 2023. No further insurance recoveries are expected to be available. Cumulative Wildfire loss payments to date through June 30, 2024 were approximately $775 million and an additional $246 million was paid subsequent to June 30, 2024. To date, PacifiCorp has reached additional settlements associated with the Wildfires totaling $199 million that have yet to be paid. As a result of the settlements, various scheduled trials have been cancelled. Estimated unpaid liabilities for the Wildfires were approximately $1.9 billion at June 30, 2024.

It is reasonably possible PacifiCorp will incur significant additional Wildfire losses beyond the amounts currently accrued; however, it is currently unable to reasonably estimate the range of possible additional losses that could be incurred due to the number of properties and parties involved, including claimants in the class to the James case, the variation in those types of properties and the ultimate outcome of legal actions.

HomeServices of America, Inc.

HomeServices of America, Inc. (“HomeServices”) is currently defending against several antitrust cases, all in federal district courts. In each case, plaintiffs claim HomeServices and certain of its subsidiaries (and in one case BHE) conspired with co-defendants to artificially inflate real estate commissions by following and enforcing multiple listing service (“MLS”) rules that require listing agents to offer a commission split to cooperating agents in order for the property to appear on the MLS (“Cooperative Compensation Rule”). None of the complaints specify damages sought. However, two cases also allege Texas state law deceptive trade practices claims, for which plaintiffs have provided written notice of the damages sought totaling approximately $9 billion by separate notice as required by Texas law.

Inone of these cases, Burnett (formerly Sitzer) et al. v. HomeServices of America, Inc. et al. (the “Burnett case”), a jury trial in the U.S. District Court for the Western District of Missouri commenced on October 16, 2023, and the jury returned a verdict for the plaintiffs on October 31, 2023, finding that the named defendants participated in a conspiracy to follow and enforce the Cooperative Compensation Rule, which conspiracy had the purpose or effect of raising, inflating, or stabilizing broker commission rates paid by home sellers. The jury further found that the class plaintiffs had proved damages in the amount of $1.8 billion. Joint and several liability applies for the co-defendants. Federal law authorizes trebling of damages and the award of pre-judgment interest and attorney fees. To date, all co-defendants have reached settlements with the plaintiffs. The U.S District Court approved certain of these settlements in May 2024, which has been appealed to the U.S. Court of Appeals for the Eighth Circuit.

In April 2024, HomeServices agreed to terms with the plaintiffs to settle all claims asserted against HomeServices and its subsidiaries in the Burnett case as part of a proposed nationwide class settlement. The final settlement agreement, which includes scheduled payments over the next four years aggregating $250 million, has yet to be filed with the court and is ultimately subject to court approval. If the settlement is not approved by the court, HomeServices intends to vigorously appeal on multiple grounds the jury’s findings and damage award in the Burnett case, including whether the case can proceed as a class action. The appeals process and further actions could take several years.

Berkshire and certain of its subsidiaries are also involved in other kinds of legal actions, some of which assert or may assert claims or seek to impose fines and penalties. We currently believe that liabilities that may arise as a result of such other pending legal actions will not have a material effect on our consolidated financial condition or results of operations.
