46、ated 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 Berkshires most recently issued

47、Annual Report on Form 10-K(“Annual Report”),which includes information necessary or useful to understanding Berkshires businesses and financial statement presentations.Our significant accounting policies and practices were presented as Note 1 to the Consolidated Financial Statements included in the

48、Annual Report.Financial information in this Quarterly Report reflects all adjustments(consisting only of normal recurring 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

49、the United States(“GAAP”).For a number of reasons,our results for interim periods are not normally 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 liabi

50、lities 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 wil

51、l produce significant volatility in our interim and annual earnings.In addition,the magnitude of 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.T

52、o varying degrees,the consequences of the COVID-19 pandemic continue to affect our operating businesses.Significant government and private sector actions have been taken since 2020 to control the spread and mitigate the economic effects of the virus and its variants.The development of geopolitical c

53、onflicts,supply chain disruptions and government actions to slow inflation in recent years have produced varying effects on our operating businesses.The economic effects from these events over longer terms cannot be reasonably estimated at this time.Accordingly,significant estimates used in the prep

54、aration 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

55、 subject to significant adjustments in future periods.Note 2.New accounting pronouncements We adopted Accounting Standards Update 2018-12“Targeted Improvements to the Accounting for Long Duration Contracts”(“ASU 2018-12”)as of January 1,2023,which modifies the accounting,reporting and disclosures re

56、lated to long duration insurance contracts and most significantly the measurement of our long duration life,annuity and health benefit liabilities.ASU 2018-12 was applied retrospectively to contracts in-force beginning as of January 1,2021(the“transition date”).The Consolidated Financial Statements

57、for 2022 and 2021 were revised to reflect the effects of the adoption of ASU 2018-12.As of the transition date,the after-tax impact of changes in cash flow assumptions were recorded in retained earnings and the after-tax effect of changes in discount rates assumptions were recorded in accumulated ot

58、her comprehensive income.The effects of the adoption of ASU 2018-12 on our Consolidated Financial Statements as of January 1,2021 and for the years ending December 31,2022 and 2021 are included in Part II,Item 5 of this Report.Beginning as of January 1,2021,the cash flow assumptions used in measurin

59、g benefit liabilities are reviewed at least annually,with the effects of assumption changes recorded in earnings.Further,the discount rate assumptions used in measuring benefit liabilities are revised each quarterly reporting period based on the prevailing observable upper-medium grade(generally con

60、sidered to be single A-rated credit ratings)corporate bond yields that reflect the duration characteristics and currency attributes of the liabilities,using interpolation for durations between the observable yields.Changes to benefits liabilities arising from changes in discount rate assumptions are

61、 recorded in other comprehensive income.In measuring benefit liabilities and amortizing capitalized acquisition costs under long duration insurance contracts,we generally aggregate contracts by issuance year.ASU 2018-12 also requires certain disclosures for long duration insurance liabilities.See No

66、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

67、 in Pilot Travel Centers,LLC(“Pilot”)for approximately$8.2 billion.We previously owned a 38.6%interest in Pilot and accounted for that investment under the equity method.We now control Pilot for financial reporting purposes.We applied the equity method through the end of January 2023 and began conso

68、lidating Pilots financial statements in our Consolidated Financial Statements on February 1,2023.Pilot is headquartered in Knoxville,Tennessee and operates travel centers in North America(primarily under the names Pilot or Flying J)with more than 650 travel center locations across 43 U.S.states and

69、six Canadian provinces.Pilot also has over 150 retail locations in the U.S.and Canada where it sells diesel fuel through various arrangements with third party travel centers.Among its business activities,Pilot operates large wholesale fuel and fuel marketing platforms in the U.S.and operates a water

70、 hauling and disposal business in the oil fields sector.As Pilots most significant business activities include involve purchasing and selling fuel(energy)on a wholesale and retail basis,and engaging in other energy-related business activities,including oil field services,we have included Pilot withi

71、n the railroad,utilities and energy sections of our Consolidated Balance Sheet and Consolidated Statement of Earnings beginning February 1,2023.Pilots revenues and net earnings attributable to Berkshire shareholders included in Berkshires Consolidated Financial Statements for the two months ending M

72、arch 31,2023 were$9.5 billion and$83 million,respectively.Our equity method earnings from Pilot for the month of January 2023 were$105 million.In applying the acquisition method of accounting,we were required to remeasure our previously held 38.6%investment in Pilot to fair value.In the first quarte

73、r of 2023,we recognized a one-time,non-cash remeasurement gain of approximately$3.0 billion,representing the excess of the fair value of that interest over the carrying value under the equity method,as a component of investment gains(losses).9Notes to Consolidated Financial Statements(Continued)Note

74、 3.Significant business acquisitions(Continued)Under the terms of an agreement,the holder of the remaining noncontrolling interest in Pilot has the option to require us to redeem for cash,all or a portion of the interest beginning in 2024.The cash consideration will be based on Pilots future earning

75、s,cash and debt.We have concluded that the remaining Pilot noncontrolling interest represents a redeemable interest under GAAP and are presenting such interests between liabilities and shareholders equity in the Consolidated Balance Sheet.We valued the noncontrolling interest at fair value as of the

76、 acquisition date.Thereafter,we will increase or decrease the redeemable noncontrolling interest by the share of the earnings or losses attributable to the interest and will further adjust the balance,as appropriate,if the current estimated redemption value exceeds the carrying value.The preliminary

77、 values of the Pilot identified assets acquired,liabilities assumed and redeemable noncontrolling interests are summarized as follows(in millions).Valuations of certain assets and liabilities,including property plant and equipment,other intangible assets and goodwill,as of the acquisition date have

93、to acquire common stock of Occidental Petroleum Corporation(“Occidental”).Our aggregate voting interest in Occidental exceeded 20%on August 4,2022 and we adopted the equity method as of that date.See Note 6.We report our investments in Occidental Cumulative Perpetual Preferred Stock and Occidental c

94、ommon stock warrants at fair value as equity securities,as such interests are not in-substance common stock under GAAP and are not eligible for the equity method.As of March 31,2023,our investment in Occidental preferred stock had an aggregate liquidation value of approximately$9.5 billion.During Ma

95、rch of 2023,Occidental issued mandatory redemption notifications at a price of 110%of the liquidation value,plus accrued and unpaid dividends for$474 million of preferred stock liquidation value due to excess distributions by Occidental to its common stockholders,as defined under the agreement.The p

96、referred 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.Our investment in Occidental warrants allows us to purchase up to 83.86 million

97、shares of Occidental common stock at an exercise price of$59.62 per share.The warrants are exercisable in whole or in part until one year after the redemption of the preferred stock.As of March 31,2023,we owned 151.6 million shares of American Express Company(“American Express”)common stock represen

98、ting 20.4%of the American Express 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 passiv

99、ity 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

100、 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

101、our investments in the common stock of The Kraft Heinz Company(“Kraft Heinz”)and Occidental.We own 26.5%of Kraft Heinz common stock and we own 23.5%of Occidental common stock,which excludes the potential effect of the exercise of the Occidental common stock warrants that are included in investments

102、in equity securities.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 explora

200、lue 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

201、 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

202、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 observa

203、ble 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

204、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

205、 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

217、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

218、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.Berkshires

251、 data(Note 25 to the accompanying Consolidated Financial Statements)should be read in conjunction with this discussion.To varying degrees the consequences of the COVID-19 pandemic continue to affect our operating businesses.Government and private sector actions were taken beginning in 2020 intended

252、to control the spread and mitigate the adverse economic effects of the virus and its variants.The development of global geopolitical conflicts,supply chain disruptions and government actions to slow inflation in recent years has produced varying economic effects on our operating businesses.We cannot

253、 reliably predict the future economic effects of these events on our businesses.Insurance underwriting generated after-tax earnings of$911 million in the first quarter of 2023 and$167 million in the first quarter of 2022,which was revised from the previously reported amount of$47 million as a result

254、 of the adoption of ASU 2018-12 on January 1,2023.See Note 2 to the accompanying Consolidated Financial Statements.After-tax earnings from insurance investment income increased$799 million in the first quarter of 2023 compared to 2022,mostly attributable to increases in short-term interest rates.Aft

255、er-tax earnings of BNSF decreased 9.0%in the first quarter of 2023 compared to 2022.The comparative decrease was primarily attributable to lower overall freight volumes and higher fuel and other operating costs.After-tax earnings of BHE decreased 46.3%in the first quarter of 2023 compared to 2022.Th

256、e decrease reflected lower earnings from the U.S.regulated utilities,other energy businesses and real estate brokerage businesses.As disclosed in Note 3 to the accompanying Consolidated Financial Statements,we increased our ownership in Pilot from 38.6%to 80%on January 31,2023 and we are consolidati
