Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
General | 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 (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 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 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 on equity securities will produce significant volatility in our interim and annual earnings. In addition, changes in the fair values of certain derivative contract liabilities, gains and losses from the periodic revaluation of certain assets and liabilities denominated in foreign currencies and the magnitude of asset impairment charges can cause significant variations in periodic net earnings. 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 and in particular during the second quarter, although the effects varied significantly. The extent of the effects over longer terms cannot be reasonably estimated at this time. Risks and uncertainties resulting from the pandemic that may affect our future earnings, cash flows and financial condition include the ability to vaccinate a significant number of people in the U.S. and throughout the world as well as the long-term effect from the pandemic on the demand for certain of our products and services. 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. |

Accounting Changes And Error Corrections [Abstract] | |
New accounting pronouncements | Note 2. New accounting pronouncements 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 based on the prevailing facts and circumstances. 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, which was primarily related to our manufactured housing loans. In August 2018, the FASB issued ASU 2018-12 “Targeted Improvements to the Accounting for Long-Duration Contracts.” ASU 2018-12 requires periodic reassessment of actuarial and discount rate assumptions used to value policyholder liabilities and deferred acquisition costs of long-duration insurance and reinsurance contracts, with the effects of changes in cash flow assumptions reflected in earnings and the effects of changes in discount rate assumptions reflected in other comprehensive income. Currently, the actuarial and discount rate assumptions are set at the contract inception date and not subsequently changed, except under limited circumstances. ASU 2018-12 requires new disclosures and is effective for fiscal years beginning after December 15, 2022, with early adoption permitted. We are evaluating the effect this standard will have on our Consolidated Financial Statements. |

Equity Method Investments And Joint Ventures [Abstract] | |
Equity method investments | Note 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 325,442,152 shares of Kraft Heinz common stock representing 26.6% of the outstanding shares. Our investment in Kraft Heinz produced an equity method loss of $7 million in the second quarter and earnings of $143 million in the first six months of 2021. In 2020, we recorded losses attributable to Kraft Heinz of $440 million in the second quarter and $339 million in the first six months which included our proportionate share of the goodwill and intangible asset impairment charges recorded by Kraft Heinz of approximately $700 million for the second quarter and $750 million for the first six months. We received dividends on the common stock of $260 million in each of the first six months of 2021 and 2020, which were recorded as reductions to the carrying value of our investment. Shares of Kraft Heinz common stock are publicly-traded and the fair value of our investment was approximately $13.3 billion at June 30, 2021 and $11.3 billion at December 31, 2020. The carrying value of our investment was approximately $13.3 Summarized consolidated financial information of Kraft Heinz follows (in millions).

Other investments that we account for pursuant to the equity method include Berkadia Commercial Mortgage LLC (“Berkadia”), Pilot Travel Centers LLC (“Pilot”) and Electric Transmission Texas, LLC (“ETT”). The aggregate carrying value of these investments was approximately $3.2 billion as of June 30, 2021 and $4.0 billion as of December 31, 2020. Our equity method earnings from these entities in the first six months were $255 million in 2021 and $382 million in 2020. During the first six months of 2021, we received distributions from these other investees of $982 million, including a non-recurring distribution received from Pilot of $849 million in the first quarter. 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 provides capital solutions, investments sales advisory and mortgage servicing for multifamily and commercial real estate. A source of funding for Berkadia’s operations is through commercial paper, which was $1.47 billion at June 30, 2021 and is limited to $1.5 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.

As reflected in the Consolidated Statements of Cash Flows, we received proceeds from sales of equity securities of approximately $8.6 billion in the first six months of 2021 and $15.7 billion in the first six months of 2020. In the preceding table, investment gains and losses on equity securities sold during the period reflect the difference between the sales proceeds and the fair value of the equity securities sold at the beginning of the applicable quarterly period or, if later, the purchase date. Our taxable gains/losses on equity securities sold are generally the difference between the proceeds from sales and original cost. Taxable gains in the second quarter and first six months of 2021 were $228 million and $2.0 billion, respectively, and taxable losses were $4.5 billion and $3.3 billion in the second quarter and first six months of 2020, respectively. 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).

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. Substantially all open contracts as of June 30, 2021 will expire by February 2023. Future payments, if any, under any given contract will be required if the prevailing index value is below the contract strike price at the contract expiration date. We received aggregate premiums on the contract inception dates of $1.9 billion with respect to unexpired contracts as of June 30, 2021 and we have no counterparty credit risk. |

Intangible assets with indefinite lives were $18.3 billion as of June 30, 2021 and December 31, 2020 and primarily related to certain customer relationships and trademarks and trade names. During 2020, we concluded it was necessary to reevaluate goodwill and indefinite-lived intangible assets of certain of our reporting units for impairment due to the disruptions arising from the COVID-19 pandemic. We recorded pre-tax goodwill impairment charges of approximately $10 billion and pre-tax indefinite-lived intangible asset impairment charges of $638 million in the second quarter of 2020. Approximately $10 billion of these charges related to Precision Castparts Corp. (“PCC”), the largest business within Berkshire's manufacturing segment. The carrying value of PCC-related goodwill and indefinite-lived intangible assets prior to the impairment charges was approximately $31 billion. |

We recorded a net reduction of estimated ultimate liabilities for prior accident years of $1.1 billion in the first six months of 2021 compared to a net increase of $189 million in 2020, which produced a corresponding decrease in 2021 and an increase in 2020 in incurred losses and loss adjustment expenses. These amounts represented 1.4% in 2021 and 0.3% in 2020 of the net liabilities at the beginning of each year. Estimated ultimate liabilities for prior years’ loss events in the first six months were reduced $1.1 billion in 2021 and $250 million in 2020 with respect to primary insurance. In each period, the reductions were primarily attributable to private passenger automobile, medical professional liability and workers’ compensation claims. Estimated ultimate liabilities for prior years’ loss events related to reinsurance assumed in the first six months increased $35 million in 2021 and $439 million in 2020, which included increased provisions for legacy casualty exposures. |

Retroactive reinsurance contracts | Notes to Consolidated Financial Statements (Continued) Note 14. 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, once 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 six-month periods ending June 30, 2021 and 2020 follow (in millions). 2021 2020 Unpaid losses and loss adjustment expenses Deferred charges reinsurance assumed Unpaid losses and loss adjustment expenses Deferred charges reinsurance assumed Balances at beginning of year $ 40,966 $ (12,441 ) $ 42,441 $ (13,747 ) Incurred losses and loss adjustment expenses: Current year contracts 82 — — — Prior years’ contracts (3 ) 473 24 554 Total 79 473 24 554 Paid losses and loss adjustment expenses (808 ) — (628 ) — Balances at June 30 $ 40,237 $ (11,968 ) $ 41,837 $ (13,193 ) Incurred losses and loss adjustment expenses, net of deferred charges $ 552 $ 578 In the preceding table, classifications of incurred losses and loss adjustment expenses are based on the inception dates of the contracts, which reflects when our exposure to losses begins. Incurred losses and loss adjustment expenses for prior years’ contracts were $470 million in 2021 and $578 million in 2020, which consisted of recurring amortization of deferred charges and the effects of changes in the expected timing and amount of future loss payments. Berkshire’s subsidiary, National Indemnity Company (“NICO”), is party to a contract with certain subsidiaries of American International Group, Inc. (collectively, “AIG”), in which NICO’s ultimate liability is contractually limited to $20 billion. Our estimated unpaid claim liabilities with regard to the AIG contract were approximately $17.1 billion at June 30, 2021, reflecting paid claims of $549 million during the first six months of 2021, and $17.7 billion at December 31, 2020. Deferred charge assets related to the AIG contract were approximately $5.1 billion at June 30, 2021 and $5.4 billion at December 31, 2020. |

Notes payable and other borrowings (Continued) In the first quarter of 2021, Berkshire repaid €550 million and $1.0 billion of maturing senior notes and issued €600 million of 0.5% senior notes due in 2041. In April 2021, Berkshire issued ¥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%. 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 January 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 at June 30, 2021) 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 $675 million in the first six months of 2021 and $102 million in the first six months of 2020. In addition to BHFC borrowings, Berkshire guaranteed approximately $4.0 billion of other subsidiary borrowings at June 30, 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 Interest Rate June 30, 2021 December 31, 2020 Railroad, utilities and energy: Berkshire Hathaway Energy Company (“BHE”) and subsidiaries: BHE senior unsecured debt due 2023-2051 4.3 % $ 13,000 $ 13,447 Subsidiary and other debt due 2021-2064 4.2 % 35,873 36,420 Short-term borrowings 1.5 % 2,536 2,286 Burlington Northern Santa Fe ("BNSF") and subsidiaries due 2021-2097 4.6 % 23,253 23,220 $ 74,662 $ 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 such debt. These borrowing arrangements generally contain various covenants, which pertain to leverage ratios, interest coverage ratios and/or debt service coverage ratios. In the first six months of 2021, BHE and its subsidiaries repaid $1.7 billion of term debt. In April 2021, a BHE subsidiary issued $550 million of 3.4% term debt due in 2051. BNSF’s borrowings are primarily senior unsecured debentures. During the first six months of 2021, BNSF repaid $886 million of debt. In April 2021, BNSF issued $925 million of 3.3% term debt due in 2051. As of June 30, 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. As of June 30, 2021, our subsidiaries had unused lines of credit and commercial paper capacity aggregating approximately $9.9 billion to support short-term borrowing programs and provide additional liquidity. Such unused lines of credit included approximately $8.4 billion related to BHE and its subsidiaries. |

These investments are subject to contractual restrictions on transferability and may contain provisions that 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. Notes to Consolidated Financial Statements (Continued) Note 16. Fair value measurements (Continued) Our equity index put option derivative contracts are illiquid and contain contract terms that are not standard in derivatives markets. For example, we are not required to post collateral under most of our contracts. We determine the fair value of the equity index put option contract liabilities based on the Black-Scholes option valuation model. |

Class B common stock possesses dividend and distribution rights equal to one-fifteen-hundredth one-ten-thousandth 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) (1/1,500) Berkshire’s common stock repurchase program permits Berkshire to repurchase its Class A and Class B 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 Bills 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. |

Income taxes | Note 18. Income taxes Our consolidated effective income tax rates were 20.4% for the second quarter and 19.9% for the first six months of 2021 compared to 25.4% for the second quarter and 15.7% for the first six months of 2020. Our effective income tax rate normally reflects recurring benefits from dividends-received deductions applicable to investments in 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, the magnitude of 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. |

Commitments And Contingencies Disclosure [Abstract] | |
Contingencies and commitments | Note 21. 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. On November 1, 2020, Berkshire Hathaway Energy (“BHE”) acquired a large portion of the natural gas transmission and storage business of Dominion Energy, Inc. (“Dominion”) for approximately $2.5 billion. The acquisition included a partial ownership of a liquefied natural gas export, import and storage facility (“Cove Point”), consisting of 100% of the general partnership interest and 25% of the limited partnership interests. We treat Cove Point as a consolidated subsidiary because we have the power to direct the activities that most significantly affect its economic performance and the obligation to absorb losses and the right to receive benefits which could be significant to Cove Point. The preliminary fair value of the assets acquired was $13.4 billion, including residual goodwill of $1.7 billion, and the fair value of the liabilities assumed was $7.0 billion, including the assumption of approximately $5.6 billion of debt. We also recorded noncontrolling interests of $3.9 billion attributable to limited partnership interests in Cove Point that are held by third parties. In addition, BHE previously agreed to acquire certain other of Dominion’s pipeline business for approximately $1.3 billion. Effective July 9, 2021, BHE and Dominion agreed to terminate this planned transaction due to ongoing uncertainty in obtaining the necessary regulatory approvals. |

Business segment data | Note 23. 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.

Accounting Changes And Error Corrections [Abstract] | |
New accounting pronouncements | 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 based on the prevailing facts and circumstances. 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, which was primarily related to our manufactured housing loans. In August 2018, the FASB issued ASU 2018-12 “Targeted Improvements to the Accounting for Long-Duration Contracts.” ASU 2018-12 requires periodic reassessment of actuarial and discount rate assumptions used to value policyholder liabilities and deferred acquisition costs of long-duration insurance and reinsurance contracts, with the effects of changes in cash flow assumptions reflected in earnings and the effects of changes in discount rate assumptions reflected in other comprehensive income. Currently, the actuarial and discount rate assumptions are set at the contract inception date and not subsequently changed, except under limited circumstances. ASU 2018-12 requires new disclosures and is effective for fiscal years beginning after December 15, 2022, with early adoption permitted. We are evaluating the effect this standard will have on our Consolidated Financial Statements. |
