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. ~~Changes to those policies due to the adoption of new accounting standards are described in Note 2.~~

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.~~March of 2020. The COVID-19 ~~has since~~pandemic adversely affected nearly all of our operations during 2020 and in particular during the second quarter, although the effects ~~are varying~~varied significantly. The ~~duration and~~ extent of the effects over longer terms cannot be reasonably estimated at this time. ~~The risks~~Risks and uncertainties resulting from the pandemic that may affect our future earnings, cash flows and financial condition include the ~~time necessary~~ability to ~~develop~~vaccinate a significant number of people in the U.S. and ~~produce a safe and effective vaccine that can be widely distributed~~ throughout the world ~~and~~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. Additionally, GEICO’s underwriting results will likely be negatively affected over the remainder of the year and in the first quarter of 2021, as the remaining impact of the GEICO Giveback program (a program whereby all voluntary auto and motorcycle insurance policies renewed and newly issued during the period between April 8, 2020 and October 7, 2020 receive a 15% premium rate reduction) will be reflected in earned premiums during these periods.

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. ~~We elected to not measure an allowance for expected credit losses on accrued interest and instead reverse uncollectible accrued interest through interest income on a timely basis.~~

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. Expected credit losses for such financial assets are based on the net present value of future principal payments less estimated expenses related to the charge-off and foreclosure of expected uncollectible loans and include provisions for loans that are not in foreclosure. Our principal credit quality indicator is whether the loans are performing. Expected credit loss estimates consider historical default rates, collateral recovery rates, historical runoff rates, interest rates, reductions of future cash flows for modified loans, the historical time elapsed from last payment until foreclosure, among other matters. In addition, our estimates consider current conditions and reasonable and supportable forecasts.

Trade receivables, insurance premium receivables and other receivables are primarily short-term in duration with stated collection terms of less than one year from the date of origination. In establishing credit loss allowances for such receivables, we primarily utilize credit loss history. However, credit loss allowances may be adjusted as a result of current conditions and when we expect reasonable and supportable forecasts to deviate from historical experience. In evaluating expected credit losses of reinsurance recoverables, we review the credit quality of the counterparty and consider credit ratings, right-of-offset provisions within reinsurance contracts and other forms of credit enhancement including, collateral, funds held arrangements, guarantees, as well as other publicly available information.

We adopted ASU 2017-04 “Simplifying the Test for Goodwill Impairment” as of January 1, 2020. Under ASU 2017-04, the measurement of a goodwill impairment is represented by the excess of the carrying value over the fair value of the reporting unit and is limited to the carrying value of goodwill.

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 ~~arising from~~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, ~~2021,~~2022, with early adoption permitted. We are evaluating the effect this standard will have on our Consolidated Financial Statements.

Investments in fixed maturity securities as of ~~September~~June 30, ~~2020~~2021 and December 31, ~~2019~~2020 are summarized ~~by type~~ below (in millions).

Investments in foreign governments include securities issued by national and provincial government entities as well as instruments that are unconditionally guaranteed by such entities. As of ~~September~~June 30, ~~2020,~~2021, approximately ~~87%~~89% of our foreign government holdings were rated AA or higher by at least one of the major rating agencies.

The amortized cost and estimated fair value of fixed maturity securities as of ~~September~~June 30, ~~2020~~2021 are summarized below by contractual maturity dates (in millions). Actual maturities may differ from contractual maturities due to early call or prepayment rights held by issuers.

Investments in equity securities as of ~~September~~June 30, ~~2020~~2021 and December 31, ~~2019~~2020 are summarized in the tables below (in millions).

~~On August 8, 2019, Berkshire invested a total of~~Notes to Consolidated Financial Statements (Continued)

Our equity security investments include $10 billion in Occidental Corporation (“Occidental”) ~~newly issued Occidental~~ Cumulative Perpetual Preferred Stock with an aggregate liquidation value of $10 billion and warrants to purchase up to 8083.86 million shares of Occidental common stock at an exercise price of $62.50 per share. In accordance with the terms of the warrants, on August 3, 2020, the number of shares of common stock that can be purchased was increased to 83.86 million shares and the exercise price was reduced to $59.62 per share. The preferred stock accrues dividends at 8% per annum and is redeemable at the option of Occidental commencing in 2029 at a redemption price equal to 105% of the liquidation preference plus any accumulated and unpaid dividends or is mandatorily redeemable under ~~certain~~ specified ~~capital return~~ events. Dividends on the preferred stock ~~may be paid~~are payable in cash or, at Occidental’s option, in shares of Occidental common stock. The warrants are exercisable in whole or in part until one year after the redemption of the preferred stock. ~~Our investments in Occidental are included in the commercial, industrial and other category in the preceding tables.~~

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 ~~$9.7~~$13.3 billion at ~~September~~June 30, ~~2020~~2021 and ~~$10.5~~$11.3 billion at December 31, ~~2019.~~2020. The carrying value of our investment was approximately ~~$13.1~~$13.3 billion at ~~September~~both June 30, ~~2020~~2021 and ~~$13.8 billion at~~ December 31, ~~2019.~~

~~Berkshire’s equity method earnings from Kraft Heinz were $159 million in the third quarter of~~ 2020. Equity method losses from Kraft Heinz were $180 million in the first nine months of 2020, which included approximately $850 million for our proportionate share of goodwill and identifiable intangible asset impairment charges recorded by Kraft Heinz. As previously disclosed in Berkshire’s Form 10-Q for the third quarter of 2019, Kraft Heinz’s financial statements for the first and second quarters of 2019 were not available until August 13, 2019 when Kraft Heinz filed financial statements for those periods with the Securities and Exchange Commission. Thus, Berkshire did not record equity method earnings attributable to Kraft Heinz for each of those periods until the third quarter of 2019. Berkshire’s equity method earnings in the third quarter and first nine months of 2019 included $467 million with respect to Kraft Heinz’s results for the first nine months of 2019, of which $228 million was attributable to Kraft Heinz’s results for the first six months of 2019. Berkshire’s equity method share of the Kraft Heinz goodwill and identifiable intangible asset impairment charges for the first nine months of 2019 was $293 million. We received dividends on the common stock of $391 million in each of the first nine months of 2020 and 2019, which were recorded as reductions to the carrying value of our investment.

As of September 30, 2020, the carrying value of our investment in Kraft Heinz exceeded the fair value based on the quoted market price by $3.4 billion (26% of carrying value). In light of that fact, we evaluated our investment in Kraft Heinz for impairment. We utilize no bright-line tests in such evaluations. Based on the available facts and information regarding the operating results of Kraft Heinz, our ability and intent to hold the investment until recovery, the relative amount of the decline, and the length of time that fair value was less than carrying value, we concluded that recognition of an impairment loss in earnings was not required. However, we will continue to monitor this investment and it is possible that an impairment loss will be recorded in earnings in future periods based on changes in facts and circumstances or intentions.

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

Other investments ~~accounted~~that we account for pursuant to the equity method include ~~our investments in~~ Berkadia Commercial Mortgage LLC (“Berkadia”), Pilot Travel Centers LLC (“Pilot”) and Electric Transmission Texas, LLC (“ETT”). The aggregate carrying value of ~~our~~these investments ~~in these entities~~ was approximately ~~$4.1~~$3.2 billion as of ~~September~~June 30, ~~2020~~2021 and ~~$3.7~~$4.0 billion as of December 31, ~~2019.~~2020. Our equity method earnings from these entities in the first ~~nine~~six months were ~~$513~~$255 million in ~~2020~~2021 and ~~$491~~$382 million in ~~2019.~~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 ~~is a servicer of~~provides capital solutions, investments sales advisory and mortgage servicing for multifamily and commercial real estate loans in the U.S., performing primary, master and special servicing functions for U.S. government agency programs, commercial mortgage-backed securities transactions, banks, insurance companies and other financial institutions.estate. A source of funding for Berkadia’s operations is through ~~its issuance of~~ commercial paper, which was $1.47 billion at June 30, 2021 and is ~~currently~~ limited to $1.5 billion. ~~On September 30, 2020,~~ Berkadia’s ~~commercial paper outstanding was $1.47 billion. The~~ 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.

A Berkshire Hathaway Energy Company subsidiary owns a 50% interest in ETT, an owner and operator of electric transmission assets in the Electric Reliability Council of Texas footprint. American Electric Power owns the other 50% interest. In 2017, we acquired a 38.6% interest in Pilot, headquartered in Knoxville, Tennessee. Pilot is the largest operator of travel centers in North America ~~supplying~~through more than ~~11 billion gallons of fuel per year via more than 950~~1,000 retail locations across 44 U.S. states and 6 Canadian provinces and through wholesale distribution. The Haslam family currently owns a 50.1% interest in Pilot and a third party owns the remaining 11.3% interest. We also entered into an agreement to acquire an additional 41.4% interest in Pilot in 2023, with the Haslam family retaining a 20% interest. As a result, Berkshire will become the majority owner of Pilot in 2023.

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. As reflected in the Consolidated Statements of Cash Flows, we received proceeds from sales of equity securities of approximately ~~$28.6~~$8.6 billion in the first ~~nine~~six months of ~~2020~~2021 and ~~$7.1~~$15.7 billion in the first ~~nine~~six months of ~~2019.~~2020. In the preceding table, investment ~~gains/~~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 ~~or annual~~ 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 ~~$3.9~~$228 million and $2.0 billion, respectively, and taxable losses were $4.5 billion and $3.3 billion in the ~~third~~second quarter and ~~$666 million in~~ first ~~nine~~six months of ~~2020. Taxable~~2020, respectively.

The derivative contract gains ~~were $609 million~~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).

Notional value in the ~~third quarter~~preceding table represents the aggregate undiscounted amounts payable assuming the value of each index is zero at each contract’s expiration date. Intrinsic value is the undiscounted liability assuming the contracts are settled based on the index values and ~~$1.96~~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 ~~in first nine months~~with respect to unexpired contracts as of ~~2019.~~June 30, 2021 and we have no counterparty credit risk.

Loans and finance receivables are principally ~~installment~~manufactured home loans, ~~originated or acquired by our manufactured housing business.~~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 each of the first ~~nine~~six months of ~~2020~~2021 and ~~2019~~2020 follow (in millions).

As of ~~September~~June 30, ~~2020,~~2021, approximately 99% of ~~manufactured housing~~home loan balances were evaluated collectively for impairment. As of ~~September~~June 30, ~~2020,~~2021, we considered approximately ~~97%~~98% of the loan balances to be current as to payment status. A summary of performing and non-performing ~~manufactured housing~~home loans before discounts and allowances by year of loan origination as of ~~September~~June 30, ~~2020~~2021 follows (in millions).

We are party to an agreement with Seritage Growth Properties to provide a $2.0 billion term loan facility, which expires on July 31, 2023. The outstanding loan under the facility was approximately $1.6 billion at ~~September~~June 30, ~~2020~~2021 and December 31, ~~2019,~~2020, and is secured by mortgages on real estate properties. In the first quarter of 2020, we provided a loan to Lee Enterprises, Inc. in connection with its acquisition of our newspaper operations and the repayment of its then outstanding credit facilities. The loan balance was $485 million as of June 30, 2021 and $524 million at ~~September 30, 2020 was $538 million.~~December 31, 2020. We are the sole lender to each of these entities and each of these loans is current as to payment status.

Other receivables ~~of insurance and other businesses~~ are comprised of the following (in millions).

~~Receivables of railroad and utilities and energy businesses are comprised of the following (in millions).~~

Provisions for credit losses ~~on receivables summarized in the preceding tables were $449 million~~ in the first ~~nine~~six months with respect to receivables summarized above were $209 million in 2021 and $424 million in 2020.

Reconciliations of the changes in the carrying value of goodwill for the first ~~nine~~six months of ~~2020~~2021 and for the year ended December 31, ~~2019~~2020 follow (in millions).

Other intangible assets and related accumulated amortization are summarized as follows (in millions).

Intangible asset amortization expense in the first ~~nine~~six months was ~~$962~~$637 million in ~~2020~~2021 and ~~$986~~$647 million in ~~2019.~~2020. Intangible assets with indefinite lives were $18.3 billion as of ~~September~~June 30, ~~2020~~2021 and ~~$19.0 billion as of~~ December 31, ~~2019~~2020 and primarily related to certain customer relationships and trademarks and trade names.

During ~~the second quarter of~~ 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 believed that the most significant of these disruptions related to the air travel and commercial aerospace and supporting industries.~~ 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.

The amounts of the impairment charges were determined based on discounted cash flow methods and reflect our current assessments of the risks and uncertainties associated with the aerospace industry. Significant judgment is required in estimating the fair value of a reporting unit and in performing impairment tests. Due to the inherent uncertainty in forecasting cash flows and earnings, actual results in the future may vary significantly from the forecasts.

Disruptions arising from the COVID-19 pandemic will likely continue to evolve and the effects on our businesses may differ from what we currently estimate. If the effects prove to be worse than is reflected in our current estimates, additional goodwill or indefinite-lived intangible asset impairment charges could be required.

We are party to derivative contracts through certain of our subsidiaries. The most significant derivative contracts consist of equity index put option contracts. The liabilities and related notional values of these contracts follow (in millions).

The equity index put option contracts are European style options written prior to March 2008 on four major equity indexes. Notional value in the preceding table represents the aggregate undiscounted amounts payable assuming the value of each index is zero at each contract’s expiration date. Certain contracts are denominated in foreign currencies and the related notional amounts are based on the foreign currency exchange rates as of the balance sheet date. These contracts produced pre-tax losses of $43 million in the third quarter and $640 million in the first nine months of 2020 and pre-tax gains of $234 million in the third quarter and $1,217 million in the first nine months of 2019.

Substantially all open contracts as of September 30, 2020 will expire by February 2023. The weighted average life of unexpired contracts at September 30, 2020 was approximately 1.25 years. 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 of $2.1 billion on the contract inception dates with respect to unexpired contracts as of September 30, 2020 and we have 0 counterparty credit risk. The aggregate intrinsic value (the undiscounted liability assuming the contracts are settled based on the index values and foreign currency exchange rates as of the balance sheet date) was $1.2 billion at September 30, 2020 and $397 million at December 31, 2019. These contracts may not be unilaterally terminated or fully settled before the contract expiration dates and the ultimate amount of cash basis gains or losses will not be determined until the contract expiration dates.

Our regulated utility subsidiaries are exposed to variations in the prices of fuel required to generate electricity, wholesale electricity purchased and sold and natural gas supplied for customers. We may use forward purchases and sales, futures, swaps and options to manage a portion of these price risks. Most of the net derivative contract assets or liabilities of our regulated utilities are probable of recovery through rates and are offset by regulatory liabilities or assets.

Our liabilities for unpaid losses and loss adjustment expenses (also referred to as “claim liabilities”) under property and casualty insurance and reinsurance contracts are based upon estimates of the ultimate claim costs associated with claim occurrences as of the balance sheet date and include estimates for incurred-but-not-reported (“IBNR”) claims. A reconciliation of the changes in claim liabilities, excluding liabilities under retroactive reinsurance contracts (see Note ~~15)~~14), for each of the ~~nine months~~six-month periods ending ~~September~~June 30, ~~2020~~2021 and ~~2019~~2020 follows (in millions).

Incurred losses and loss adjustment expenses shown in the preceding table were recorded in earnings and related to insured events occurring in the current year (“current accident year”) and events occurring in all prior years (“prior accident years”). We recorded a net ~~increase in~~reduction of estimated ultimate liabilities for prior accident years of ~~$69 million~~$1.1 billion in the first ~~nine~~six months of ~~2020 and~~2021 compared to a net ~~decrease~~increase of ~~$396~~$189 million in ~~the first nine months of 2019,~~2020, which produced a corresponding decrease in 2021 and an increase ~~and decrease~~in 2020 in incurred losses and loss adjustment expenses. These ~~changes~~amounts represented 1.4% in ~~the ultimate liability estimates as percentages~~2021 and 0.3% in 2020 of the net liabilities at the beginning of each ~~year were relatively insignificant.~~year.

~~In the first nine months of 2020, we reduced estimated~~Estimated ultimate liabilities for prior years’ loss events for primary insurance by $273 million and increased estimates for reinsurance liabilities by $342 million. The net decrease for primary insurance was primarily attributable to lower than anticipated private passenger automobile, medical professional liability and workers’ compensation claims. The net increase related to reinsurance included increased claims estimates for legacy casualty exposures. Inin the first ~~nine~~six months ~~of 2019,~~were reduced $1.1 billion in 2021 and $250 million in 2020 with respect to primary insurance. In each period, the ~~net decrease in estimated ultimate liabilities for prior accident years was~~reductions were primarily attributable to private passenger automobile, medical professional liability and workers’ compensation ~~claims, partly offset by~~claims. Estimated ultimate liabilities for prior years’ loss events related to reinsurance assumed in the first six months increased ~~liabilities~~$35 million in 2021 and $439 million in 2020, which included increased provisions for legacy casualty ~~exposures and other commercial insurance business.~~exposures.

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 ~~inception~~ 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 ~~nine months~~six-month periods ending ~~September~~June 30, ~~2020~~2021 and ~~2019~~2020 follow (in millions).

In the preceding table, classifications of incurred losses and loss adjustment expenses are based on the inception dates of the ~~contracts.~~contracts, which reflects when our exposure to losses begins. Incurred losses and loss adjustment expenses for prior years’ contracts were $470 million in ~~the first nine months related to contracts written in prior years were $866~~2021 and $578 million in 2020, ~~and $825 million in 2019. Such losses reflected the~~which consisted of recurring amortization of deferred charges and the effects of changes in the ~~estimated~~expected timing and amount of future loss payments.

Berkshire’s subsidiary, National Indemnity Company (“NICO”), is party to a contract with ~~various~~certain subsidiaries of American International Group, Inc. (collectively, “AIG”), in which NICO’s ultimate liability is contractually limited to $20 billion. Our estimated ~~ultimate~~unpaid claim liabilities with ~~respect~~regard to the AIG contract were approximately $17.1 billion at ~~both September~~June 30, ~~2020~~2021, reflecting paid claims of $549 million during the first six months of 2021, and $17.7 billion at December 31, ~~2019 were $18.2 billion.~~2020. Deferred charge assets related to the AIG contract were approximately ~~$5.8~~$5.1 billion at ~~September~~June 30, ~~2020~~2021 and ~~$6.3~~$5.4 billion at December 31, ~~2019.~~2020.

Notes payable and other borrowings are summarized below ~~(dollars in~~(in millions). The weighted average interest rates and maturity date ranges shown in the following tables are based on borrowings as of ~~September~~June 30, ~~2020.~~2021.

In ~~March 2020,~~the first quarter of 2021, Berkshire repaid ~~€1.0~~€550 million and $1.0 billion of maturing senior notes and issued ~~€1.0 billion~~€600 million of ~~0.0%~~0.5% senior notes due in ~~2025.~~2041. In April ~~2020,~~2021, Berkshire issued ~~¥195.5~~¥160 billion (approximately ~~$1.8~~$1.5 billion) of senior notes with maturity dates ranging from ~~2023~~2026 to ~~2060~~2041 and a weighted average interest rate of ~~1.07%~~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 ~~the first nine months of 2020,~~January 2021, BHFC repaid ~~$350~~$750 million of maturing senior notes and issued ~~$500~~$750 million of ~~1.85%~~2.5% senior notes due in 2030. In October 2020, BHFC repaid $550 million of maturing senior notes and issued $2.5 billion of senior notes consisting of $750 million of 1.45% senior notes due in 2030 and $1.75 billion of 2.85% senior notes due in 2050.2051.

The carrying values of Berkshire and BHFC non-U.S. Dollar denominated senior notes (€~~6.85~~6.9 billion, £1.75 billion and ~~¥625.5~~¥785.5 billion ~~par)~~par at June 30, 2021) reflect the applicable ~~foreign currency~~ 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 ~~losses~~gains of ~~$549 million in the third quarter and $447~~$675 million in the first ~~nine~~six months of ~~2020~~2021 and ~~pre-tax gains of $383 million in the third quarter and $447~~$102 million in the first ~~nine~~six months of ~~2019.~~2020.

In addition to BHFC borrowings, Berkshire guaranteed approximately ~~$1.2~~$4.0 billion of other subsidiary borrowings at ~~September~~June 30, ~~2020.~~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.

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. During the first nine months of 2020, BHE and its subsidiaries issued new term debt of approximately $5.5 billion with maturity dates ranging from 2025 to 2062 and a weighted average interest rate of 3.4%. In the first ~~nine~~six months of ~~2020,~~2021, BHE and its subsidiaries repaid ~~$1.9~~$1.7 billion of ~~debt and reduced short-term borrowings. On October 29, 2020,~~term debt. In April 2021, a BHE subsidiary issued ~~$500~~$550 million of ~~1.65% senior notes~~3.4% term debt due in ~~2031 and $1.5 billion of 2.85% senior notes 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 ~~2020,~~2021, BNSF issued ~~$575~~$925 million of ~~3.05% senior unsecured debentures~~3.3% term debt due in 2051. ~~During the first nine months of 2020, BNSF repaid $541 million of debt.~~ As of ~~September~~June 30, ~~2020,~~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 ~~September~~June 30, ~~2020,~~2021, our subsidiaries had unused lines of credit and commercial paper capacity aggregating approximately ~~$9.5~~$9.9 billion to support short-term borrowing programs and provide additional liquidity. Such unused lines of credit included approximately ~~$7.8~~$8.4 billion related to BHE and its subsidiaries.

Our financial assets and liabilities are summarized below as of ~~September~~June 30, ~~2020~~2021 and December 31, ~~2019,~~2020, 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 their fair values.

The fair values of substantially all of our financial instruments were measured using market or income approaches. The hierarchy for measuring fair value consists of Levels 1 through 3, which are described below.

Level 1 – Inputs represent unadjusted quoted prices for identical assets or liabilities exchanged in active markets.

Level 2 – Inputs include directly or indirectly observable inputs (other than Level 1 inputs) such as quoted prices for similar assets or liabilities exchanged in active or inactive markets; quoted prices for identical assets or liabilities exchanged in inactive markets; other inputs that may be considered in fair value determinations of the assets or liabilities, such as interest rates and yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates; and inputs that are derived principally from or corroborated by observable market data by correlation or other means. Pricing evaluations generally reflect discounted expected future cash flows, which incorporate yield curves for instruments with similar characteristics, such as credit ratings, estimated durations and yields for other instruments of the issuer or entities in the same industry sector.

Level 3 – Inputs include unobservable inputs used in the measurement of assets and liabilities. Management is required to use its own assumptions regarding unobservable inputs because there is little, if any, market activity in the assets or liabilities and it may be unable to corroborate the related observable inputs. Unobservable inputs require management to make certain projections and assumptions about the information that would be used by market participants in valuing assets or liabilities.

Reconciliations of 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 ~~nine~~six months ended ~~September~~June 30, ~~2020~~2021 and ~~2019~~2020 follow (in millions).

Quantitative information as of ~~September~~June 30, ~~2020~~2021 with respect to 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 ~~Occidental Preferred~~certain preferred stocks and ~~Occidental~~ common stock ~~warrants. See Note 4 for information regarding these investments.~~warrants that do not have readily determinable market values as defined under GAAP. These investments are subject to contractual restrictions on transferability and may contain provisions that prevent us from economically hedging our investments. ~~In applying~~We applied discounted cash flow techniques in valuing the ~~Occidental Preferred,~~preferred stock and we made assumptions regarding the expected duration of the investment and the effects of subordination in liquidation. In valuing the ~~Occidental~~ 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.

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.

~~As described in~~ Note 12, we recorded goodwill and indefinite-lived intangible asset impairment charges in the second quarter of 2020. These charges reflected our estimates of fair values of the related reporting units for goodwill and of the indefinite-lived intangible assets, and the related measurements are considered Level 3 measurements.

In estimating fair values of reporting units and indefinite-lived intangible assets, we consider the available facts and circumstances concerning the reporting unit and the industries in which it operates. The key assumptions and inputs we generally use in such determinations include forecasting revenues and expenses, cash flows and capital expenditures, as well as the selection of a discount rate and other inputs. These inputs also include our qualitative assessment of risks and uncertainties. We utilized discounted cash flow/earnings methods to develop our estimates of the fair values and we also considered other publicly available information.

Estimates of the fair value of reporting units can be significantly affected by expectations of the severity, duration or long-term effects of the COVID-19 pandemic on the reporting unit’s business, which we cannot reliably predict at this time. Consequently, fair value estimates in such instances may be subject to wide variations. We concluded it was appropriate to reflect the increased risks and uncertainties precipitated by the pandemic through a combination of increases in discount rates and reductions to operating and long-term growth assumptions. We also incorporated forecasted operating results that were reduced from what was used in estimating fair value in connection with the 2019 annual impairment test conducted during the fourth quarter.

Changes inin Berkshire’s issued, treasury and outstanding common stock during the first ~~nine~~six months of ~~2020~~2021 are shown in the table below. In addition to our common stock, 1,000,000 shares of preferred stock are authorized, but NaN are issued.

Each Class A common share is entitled to 1 vote per share. Class B common stock possesses dividend and distribution rights equal to one-fifteen-hundredth (1/1,500) of such rights of Class A common stock. Each Class B common share possesses voting rights equivalent to one-ten-thousandth (1/10,000) of the voting rights of a Class A share. Unless otherwise required under Delaware General Corporation Law, Class A and Class B common shares vote as a single class. Each share of Class A common stock is convertible, at the option of the holder, into 1,500 shares of Class B common stock. Class B common stock is not convertible into Class A common stock. On an equivalent Class A common stock basis, there were ~~1,570,636~~1,511,229 shares outstanding as of ~~September~~June 30, ~~2020~~2021 and ~~1,624,958~~1,543,960 shares outstanding as of December 31, ~~2019.~~2020.

Since we have two classes of common stock, we provide earnings per share data on the Consolidated Statements of Earnings for average equivalent Class A shares outstanding and average equivalent Class B shares outstanding. Class B shares are economically equivalent to one-fifteen-hundredth (1/1,500) of a Class A share. Average equivalent Class A shares outstanding represents average Class A shares outstanding plus one-fifteen-hundredth (1/1,500) of the average Class B shares outstanding. Average equivalent Class B shares outstanding represents average Class B shares outstanding plus 1,500 times the average Class A shares outstanding.

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 ~~$20~~$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.

Our consolidated effective income tax rates were ~~19.8%~~20.4% for the ~~third~~second quarter and ~~30.8%~~19.9% for the first ~~nine~~six months of ~~2020 and 18.7%~~2021 compared to 25.4% for the ~~third~~second quarter and ~~20.2%~~15.7% for the first ~~nine~~six months of ~~2019.~~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, ~~and~~the amount of non-deductible goodwill impairment charges and other expenses and the underlying income tax rates applicable in the various taxing jurisdictions.

A summary of supplemental cash flow information is presented in the following table (in millions).

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.

~~In July~~On November 1, 2020, Berkshire Hathaway Energy (“BHE”) ~~reached~~acquired a ~~definitive agreement with Dominion Energy, Inc. (“Dominion”) to acquire substantially all~~large portion of ~~Dominion’s~~the natural gas transmission and storage business ~~which includes more than 7,700 miles~~ of ~~natural gas transmission pipelines, about 900 billion cubic feet of operated natural gas storage capacity and~~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.~~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 ~~agreement provided for an aggregate acquisition price~~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 ~~$4.0 billion and that BHE would also assume approximately $5.7~~$5.6 billion of ~~existing asset-related long-term~~ 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.

On October 5, 2020, BHE and Dominion agreed, as permitted under the acquisition agreement, to provide for the acquisition of all originally agreed upon businesses, except for certain pipeline assets (the “Excluded Assets”), for approximately $2.7 billion in cash and BHE’s assumption of approximately $5.3 billion of debt. This acquisition was completed on November 1, 2020. In addition, on October 5, 2020, BHE and Dominion entered into a second acquisition agreement providing for BHE’s acquisition of the Excluded Assets for approximately $1.3 billion in cash and BHE’s assumption of approximately $0.4 billion of debt. The closing of this acquisition is subject to receiving necessary regulatory approvals and other customary closing conditions and is expected to occur in early 2021.

We recognize revenue when a good or service is transferred to a customer. A good or service is transferred when or as the customer obtains control of that good or service. Revenues are based on the consideration we expect to receive in connection with our promises to deliver goods and services to our customers.

The following tables summarize customer contract revenues disaggregated by reportable segment and the source of the revenue for the ~~third~~second quarter and first ~~nine~~six months of ~~2020~~2021 and ~~2019~~2020 (in millions). Other revenues included in consolidated revenues were primarily insurance premiums earned, interest, dividend and other investment income and leasing revenues, which are not considered to be revenues from contracts with customers under GAAP.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Net ~~earnings~~earnings/loss attributable to Berkshire Hathaway shareholders are disaggregated in the table that follows. Amounts are after deducting income taxes and exclude earnings attributable to noncontrolling interests (in millions).

Through our subsidiaries, we engage in ~~a number of~~numerous diverse business activities. We manage our operating businesses on an unusually decentralized basis. There are ~~essentially no~~few centralized or integrated business ~~functions and there is minimal involvement by our corporate headquarters in the day-to-day business activities of the operating businesses.~~functions. Our senior corporate management team participates in and is ultimately responsible for significant capital allocation decisions, investment activities and the selection of the Chief Executive to head each of the operating businesses. The business segment data (Note 2423 to the accompanying Consolidated Financial Statements) should be read in conjunction with this discussion.

~~As the~~The COVID-19 pandemic ~~accelerated beginning in the second half of March,~~negatively affected most of our operating businesses ~~were negatively affected,~~beginning in March of 2020, with the initial effects to date ranging from relatively minor to severe. ~~Revenues and earnings~~Earnings of most of our manufacturing, service and retailing businesses declined considerably, and in certain instances severely, in the second quarter ~~due to closures~~ of ~~facilities where crowds gather, such as retail stores, restaurants and entertainment venues, public travel restrictions and from closures of certain of our businesses. In~~2020.

In response to the effects of the pandemic, our businesses have implemented various business continuity plans to protect our employees and customers. Such plans include a variety of actions, such as temporarily closing certain retail stores, manufacturing facilities and service centers of businesses that were not subject to government mandated closure. Our businesses have also implemented practices to protect employees while at work. Such practices have included work-from-home, staggered or reduced work schedules, increased cleaning and sanitation of work spaces, providing employee health screenings, eliminating non-essential travel and face-to-face meetings and providing general health reminders intended to lower the risk of spreading COVID-19.

We have taken actions in response to the economic losses from reductions in consumer demand for products and services we offer and our inability to produce goods and provide services at certain of our businesses. These actions have included employee furloughs, wage and salary reductions, capital spending reductions and other actions intended to help mitigate the economic losses and preserve capital and liquidity. Certain of our businesses are undertaking and will likely continue to undertake restructuring activities that will resize their operations to better fit expected customer demand.higher input costs. We cannot reliably predict future economic effects of the pandemic or when business activities at our ~~numerous and diverse~~ operations will completely normalize. Nor can we predict how these events will alter the future consumption patterns of consumers and businesses we serve.

Our management views our insurance businesses as possessing two distinct activities – underwriting and investing. Underwriting decisions are the responsibility of the unit managers, while investing decisions are the responsibility of Berkshire’s Chairman and CEO, Warren E. Buffett and Berkshire’s corporate investment managers. Accordingly, we evaluate performance of underwriting operations without any allocation of investment income or investment ~~gains/~~gains and losses. We consider investment income as an integral component of our aggregate insurance operating results. However, we consider investment gains and losses, whether realized or unrealized as ~~non-operating, based on our long-held strategy of acquiring securities and holding those securities for long periods.~~non-operating. We believe that such gains and losses are not meaningful in understanding the operating results of our insurance businesses.

The timing and amount of catastrophe losses can produce significant volatility in our periodic underwriting results, particularly with respect to our reinsurance businesses. Generally, we consider ~~pre-tax~~incurred losses in excess of $100 million from a current year catastrophic event to be significant.

Changes in estimates for unpaid losses and loss adjustment expenses, including amounts established for occurrences in prior years, can also significantly affect our periodic underwriting results. Unpaid loss estimates, including estimates under retroactive reinsurance contracts, were approximately ~~$120~~$123.2 billion as of ~~September~~June 30, ~~2020.~~2021. Our periodic underwriting results may also include significant foreign currency transaction gains and losses arising from the changes in the valuation of non-U.S. Dollar denominated liabilities of our ~~U.S. based~~U.S.-based insurance subsidiaries due to foreign currency exchange rate fluctuations.

Underwriting results of our insurance businesses are summarized below (dollars in millions).

GEICO writes private passenger automobile insurance, offering coverages to insureds in all 50 states and the District of Columbia. GEICO markets its policies mainly by direct response methods where most customers apply for coverage directly to the company via the Internet or over the telephone.

In the ~~fourth~~second quarter ~~GEICO could experience pre-tax underwriting losses if~~of 2021, average claims frequencies began to increase ~~over the same period, offsetting a portion of the pre-tax underwriting earnings generated in the first nine months of 2020.~~

Premiums written decreased 10.3% in the third quarter and 4.2% in the first nine months of 2020 compared to 2019. The GEICO Giveback program provides for a 15% premium credit to all voluntary auto and motorcycle policies renewing between April 8, 2020 and October 7, 2020, as ~~well as to any new policies written during the same period. The GEICO Giveback program reduced premiums written in the first nine months of 2020~~driving by approximately $2.8 billion. Premiums earned decreased 5.1% in the third quarter and were relatively unchanged in the first nine months of 2020 compared to 2019, which included reductions of approximately $1.0 billion in the third quarter and $1.3 billion in the first nine months attributable to the GEICO Giveback program. Premiums earned will very likely decline in the fourth quarter even if policies-in-force and exposures increase.

Voluntary auto policies-in-force grew 5.4% in the first nine months of 2020 compared to 2019. The increase resulted from a 9.1% decrease in lost policies and a 3.4% decrease in new business sales. In response to the COVID-19 pandemic, GEICO paused cancellations of insurance policies for non-payment through the end of May 2020. During the third quarter, policy cancellations for non-payment resumed leading to an 18.3% increase in lost policies for the third quarter as compared to 2019.

Losses and loss adjustment expenses decreased $486 million (6.6%) in the third quarter and $1.9 billion (9.2%) in the first nine months of 2020 compared to 2019. GEICO’s ratio of losses and loss adjustment expenses to premiums earned (the “loss ratio”) decreased 1.3 percentage points in the third quarter and 7.9 percentage points in the first nine months of 2020 compared to 2019. The decreases in the loss ratio reflected declines in claims frequencies, partly offset by increases in claims severities and the impact of lower premiums earned attributable to the GEICO Giveback program.policyholders increased.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Premiums written increased $1.1 billion (14.1%) in the second quarter and $1.5 billion (8.2%) in the first six months of 2021 compared to 2020. The premium increases were primarily attributable to the $1.3 billion reduction in premiums written during the second quarter of 2020 from the GEICO Giveback Program and also by a 4.9% increase in average premiums per auto policy over the past twelve months. The GEICO Giveback program provided a 15% premium credit to all new and renewal voluntary auto and motorcycle policies written between April 8, 2020 and October 7, 2020. Over that six-month period, the GEICO Giveback program reduced premiums written by approximately $2.9 billion. Voluntary auto policies-in-force increased approximately 183,000 during the first six months of 2021.

Premiums earned increased $506 million (5.6%) in the second quarter and $320 million (1.8%) in the first six months of 2021 compared to 2020. Premiums earned in the first six months of 2021 included reductions of approximately $460 million attributable to the remaining impact of the GEICO Giveback premium credit.

Losses and loss adjustment expenses increased $2.0 billion (35.7%) in the second quarter and $1.7 billion (13.7%) in the first six months of 2021 compared to 2020. GEICO’s ratio of losses and loss adjustment expenses to premiums earned increased 17.7 percentage points in the second quarter and 8.0 percentage points in the first six months of 2021 compared to the same periods in 2020. The increases reflected overall increases in average claims frequencies and severities, partially offset by increased reductions of claim loss estimates for prior years’ loss events.

Generally, we strive to generate underwriting profits. However, time-value-of-money concepts are important elements in establishing prices for retroactive reinsurance and periodic payment annuity businesses due to the expected long durations of the liabilities. We expect to incur pre-tax underwriting losses from such businesses, primarily through deferred charge amortization and discount accretion charges. We receive premiums at the inception of these contracts, which are then available for investment.

Losses and loss adjustment expenses in the first six months of 2020 included a net increase in estimated ultimate liabilities for prior years’ loss events of ~~$342~~$439 million, ~~in 2020 compared to a net decrease of $75 million in 2019. The increase in 2020 was~~ primarily attributable to an increase in legacy environmental, asbestos and other latent injury ~~claims. Underwriting~~liabilities recorded in the second quarter. In 2020, losses and loss adjustment expenses also included approximately $350 million in the second quarter and $575 million in the first ~~nine~~six months attributable to the COVID-19 pandemic.

Underwriting expenses are primarily commissions and brokerage costs. The expense ratio in 2021 decreased 3.0 percentage points in the second quarter and 3.5 percentage points in the first six months compared to the same periods in 2020, attributable to changes in business mix and the impact of pandemic-related charges in the 2020 periods.

A summary of our life/health reinsurance underwriting results follows (dollars in millions).

Life/health premiums written decreased 8.6% in the second quarter and 6.2% in the first six months of 2021 compared to 2020. The decreases reflected the non-renewal in 2021 of a policy that covered U.S. health insurance risks ($198 million in the second quarter and $366 million in the first six months), partially offset by favorable foreign currency translation effects. Underwriting earnings in the first six months of 2021 were negatively affected by significant increases in mortality in the U.S., South Africa, India and Latin America, which were partially offset by lower underwriting expenses, due mainly to lower average commission rates in the international life business. Underwriting results in the first six months of 2020 ~~increased 23.8% over 2019,~~included pre-tax earnings from international life business, partially offset by pre-tax losses from U.S. life business, the run-off of long-term care business and unfavorable foreign currency translation effects.

Pre-tax underwriting losses in each period derived from deferred charge amortization and changes in the estimated timing and amounts of future claim payments. Underwriting results also include foreign currency exchange gains and losses from the effects of changes in foreign currency exchange rates on non-U.S. Dollar denominated liabilities of our U.S. subsidiaries. Before foreign currency exchange effects, pre-tax underwriting losses were $220 million in the second quarter and $463 million in the first six months of 2021. In 2020, before foreign currency exchange effects, pre-tax underwriting losses were $345 million in the second quarter and $592 million in the first six months. Foreign currency exchange gains and losses were insignificant in 2021 compared to losses of $115 million in the second quarter and gains of $90 million in the first six months of 2020.

Gross unpaid losses assumed under retroactive reinsurance contracts were $40.2 billion at June 30, 2021, declining $729 million since December 31, 2020, primarily due to ~~increased commissions expense on~~loss payments. Unamortized deferred charge assets related to such reinsurance contracts were $12.0 billion at June 30, 2021, a decline of $473 million since December 31, 2020, primarily attributable to amortization. Deferred charge assets will be charged to earnings over the ~~increased premium volume.~~expected remaining claims settlement periods through periodic amortization.

~~A summary of our life/health reinsurance underwriting results follows (dollars in millions).~~

Life/health premiums written increased $288 million (26.3%) in the third quarter and $946 million (29.5%) in the first nine months of 2020 compared to the corresponding 2019 periods. The increases were primarily attributable to a new reinsurance contract covering U.S. health insurance risks (approximately $500 million for the first nine months) and from volume growth in the Asian and European life reinsurance markets. The increase in the first nine months was partially offset by unfavorable foreign currency translation effects.

Life/health underwriting results in the third quarter and first nine months of 2020 were negatively affected by increased life benefits from COVID-19-related claim estimates ($68 million in the third quarter and $172 million in the first nine months) and increases in liabilities from changes in underlying assumptions in estimating disability benefit liabilities in Australia. Underwriting results in the first nine months of 2019 included a one-time pre-tax gain of $163 million attributable to a yearly-renewable-term life reinsurance contract amendment, partially offset by an increase in estimated disability benefit liabilities in Australia.

There were no significant retroactive reinsurance contracts written in the first nine months of 2020 and 2019. Pre-tax underwriting losses in 2020 and 2019 derived from deferred charge amortization and changes in the estimated timing and amounts of future claim payments, as well as from foreign currency gains/losses arising from the periodic remeasurement of non-U.S. Dollar denominated liabilities related to contracts written by our U.S. subsidiaries. In the first nine months, these contracts had pre-tax foreign currency remeasurement losses of $22 million in 2020 compared to pre-tax gains of $73 million in 2019. Before foreign currency gains/losses, these contracts produced pre-tax underwriting losses of $874 million in the first nine months of 2020 compared to $824 million in the first nine months of 2019.

Unpaid losses assumed under retroactive reinsurance contracts were $41.8 billion as of September 30, 2020 and $42.4 billion as of December 31, 2019. Unamortized deferred charge assets related to such reinsurance contracts were $13.0 billion as of September 30, 2020 and $13.7 billion as of December 31, 2019. Deferred charge assets will be charged to earnings over the expected remaining claims settlement periods through periodic amortization.

Nevertheless, we believe that maintaining ample liquidity is paramount and we insist on safety over yield with respect to short-term investments.

Dividend income decreased $202 million (16.5%) in the third quarter and increased $340 million (10.4%) in the first nine months of 2020 compared to 2019. The increase in the first nine months was primarily attributable to the investment in $10 billion liquidation value of 8% cumulative preferred stock of Occidental on August 8, 2019, partly offset by lower dividends from common stock investments.

The following table summarizes BNSF’s railroad freight volumes by business group (cars/units in thousands).

Railroad operating revenues ~~were $5.0 billion~~increased 26.0% in the ~~third~~second quarter and ~~$14.7 billion~~11.7% in the first ~~nine~~six months of ~~2020, representing decreases of approximately $0.8 billion (14.1%) and $2.4 billion (14.0%), respectively, versus the corresponding periods in 2019.~~2021 compared to 2020. Railroad operating revenues in ~~2020~~2021 reflected ~~lower~~higher volumes of ~~8.3%~~24.5% in the ~~third~~second quarter and ~~10.5%~~14.2% in the first ~~nine~~six months, ~~as well as~~partially offset by a ~~4.0%~~2.2% year-to-date decrease in average revenue per car/unit resulting from business mix ~~changes~~changes. Pre-tax earnings were $2.0 billion and $3.6 billion in the second quarter and first six months of 2021, increases of 32.5% and 18.2%, respectively, compared to the corresponding 2020 periods. The increases were attributable to the increased volumes and improved productivity. The COVID-19 pandemic caused a significant economic slowdown that adversely affected our volumes in 2020.

Operating revenues from consumer products were $2.1 billion in the second quarter and $4.0 billion in the first six months of 2021, increases of 32.6% and 19.1%, respectively, from 2020. Volumes increased 27.4% in the second quarter and 21.3% in the first six months of 2021, with a higher average revenue per car/unit in the second quarter and a lower average revenue per car/unit in the first six months of 2021. The volume increases resulted from growth in intermodal in both international and domestic shipments driven by increased retail sales, inventory replenishments by retailers and increased e-commerce activity, as well as from growth in automotive shipments.

Operating revenues from industrial products increased 16.6% in the second quarter to $1.4 billion and decreased 1.8% to $2.6 billion in the first six months of 2021 compared to the same periods in 2020. The decrease for the first six months was attributable to lower average revenue per car/unit due to commodity mix and lower fuel surcharge revenue. Average revenue ~~driven by~~per car/unit was also lower ~~fuel prices. Volume~~in the second quarter. Volumes increased 18.4% in the second quarter and 0.8% in the first ~~nine~~six months, ~~of 2020 was 6.88 million cars/units compared to 7.68 million cars/units in 2019. The overall volume decrease was~~ primarily due to continued recovery in the ~~COVID-19 pandemic, which severely impacted~~U.S. industrial economy, driving higher volumes ~~through~~in the construction and building sectors, partially offset by lower petroleum volumes due to reduced production and demand in the energy sector.

Operating revenues from agricultural products were $1.3 billion in the second quarter and $2.6 billion in the first ~~half~~six months of ~~the year. While monthly volumes improved sequentially~~2021, increases of 18.7% and 16.4%, respectively, from 2020. Volumes increased 13.0% in the ~~third~~second quarter and 12.3% in the first six months of 2021 as compared to 2020. The volume increases were primarily due to higher grain exports, as well as higher volumes of ethanol and related commodities. Revenue per car/unit also increased for both periods of 2021.

Operating revenues from coal were $767 million in the second quarter and $1.5 billion in the first six months of 2021, increases of 41.8% and 11.2%, respectively, from 2020, attributable to higher volumes ~~continued~~of 31.5% in the second quarter and 7.0% in the first six months, as well as from higher average revenue per car/unit. Volume increases in 2021 were attributable to ~~be negatively affected~~increased electricity generation and higher natural gas prices and from utilities rebuilding inventory in the second quarter after draw-downs earlier in the year.

Railroad operating expenses were $3.4 billion in the second quarter and $6.7 billion in the first six months of 2021, increases of $668 million (24.5%) and $577 million (9.4%), respectively, compared to the same periods in 2020. The ratio of railroad operating expenses to railroad operating revenues decreased 0.7 percentage points to 60.4% in the second quarter and 1.3 percentage points to 62.0% in the first six months of 2021 versus the 2020 periods. The increases in railroad operating expenses reflected higher volumes and higher average fuel prices, partially offset by ~~the pandemic.~~productivity improvements.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Pre-tax earnings were $1.8 billion and $4.9 billion in the third quarter and first nine months of 2020, respectively, decreases of 8.4% and 9.7%, respectively, compared to 2019. The decreases principally resulted from the negative impacts of the COVID-19 pandemic on volumes. In addition, pre-tax earnings in the first nine months of 2019 included an operating revenue increase related to the favorable outcome of an arbitration hearing and a retirement plan curtailment gain that is included in other expenses, net in the preceding table. These effects were partially offset by significant improvements in 2020 in service, velocity and cost performance compared to 2019, along with lower costs related to severe winter weather and flooding on parts of the network which negatively affected expenses and service levels in 2019.

Operating revenues from consumer products were $1.9 billion in the third quarter and $5.2 billion in the first nine months of 2020, decreases of 4.5% and 11.2%, respectively, from 2019. The decreases reflected lower average revenue per car/unit for both periods. Volumes increased 0.5% in the third quarter and decreased 6.2% in the first nine months of 2020. Increased retail sales and inventory replenishments by retailers, along with increased e-commerce activity in the third quarter resulted in higher domestic intermodal volumes for the first nine months of 2020. International intermodal volumes and automotive shipments remained low primarily attributable to the COVID-19 pandemic.

Operating revenues from industrial products were $1.2 billion in the third quarter and $3.8 billion in the first nine months of 2020, decreases of 25.1% and 17.7%, respectively, from 2019. The decreases were attributable to lower volumes of 23.0% in the third quarter and 17.4% in the first nine months of 2020, along with lower average revenue per car/unit in both periods. The volume decreases were primarily driven by a decline in U.S. industrial production due to the COVID-19 pandemic and reduced demand in the energy sector, which drove lower sand and petroleum products volume.

Operating revenues from agricultural products were $1.2 billion in the third quarter and $3.4 billion in the first nine months of 2020, an increase of 1.7% and decrease of 2.8%, respectively, from 2019. The revenue changes reflected a volume increase of 3.9% in the third quarter and about equal volume in the first nine months of 2020 as compared to 2019, along with lower revenue per car/unit for both periods. The adverse impacts of the COVID-19 pandemic on volumes, primarily for ethanol and sweeteners shipments, along with lower soybean exports, were substantially offset by higher grain and meal exports.

Operating revenues from coal were $651 million in the third quarter and $2.0 billion in the first nine months of 2020, decreases of 34.6% and 28.7%, respectively, compared to 2019. The decreases reflected lower average revenue per car/unit and lower volume of 25.3% in the third quarter and 22.6% in the first nine months. The volume declines were primarily attributable to lower electricity demand driven by impacts of the COVID-19 pandemic and mild winter weather in the first quarter, low natural gas prices and utility coal plant retirements.

Railroad operating expenses in the third quarter and first nine months of 2020 were $3.0 billion and $9.1 billion, respectively, decreases of $0.7 billion (18.0%) and $2.0 billion (18.0%), respectively, compared to the same periods in 2019. The ratio of railroad operating expenses to railroad operating revenues decreased 2.9 percentage points to 59.7% in the third quarter and 3.0 percentage points to 62.1% in the first nine months of 2020 versus the 2019 periods. Railroad operating expenses in 2020 reflected lower volume-related costs, productivity improvements, the effects of cost control initiatives and the effects of improved weather conditions compared to 2019.

Compensation and benefits expenses ~~decreased $213~~increased $169 million ~~(16.2%~~(17.3%) in the ~~third~~second quarter and ~~$705~~$108 million ~~(17.6%~~(4.9%) in the first ~~nine~~six months of ~~2020~~2021 compared to ~~2019.~~2020.

~~BNSF is an important component of the national~~increased property and global supply chain and, as an essential business, has continued to operate throughout the duration of the COVID-19 pandemic. However, the COVID-19 pandemic caused significant economic disruptions that adversely affected the demand for transportation services. The COVID-19 pandemic continues to evolve, and the full extent to which it may impact BNSF's business, operating results, financial condition, or liquidity will depend on future developments which are highly uncertain and cannot be predicted with confidence. We believe BNSF's fundamental business remains strong and it has ample liquidity to continue business operations during this volatile period.

~~Utilities and Energy (“Berkshire Hathaway Energy Company”)~~ ~~(Continued)~~

PacifiCorp operates a regulated electric utility in portions of several Western states, including Utah, Oregon and Wyoming. ~~After-tax~~PacifiCorp after-tax earnings increased $8$59 million ~~(2.9%)~~ in the ~~third~~second quarter and $3$52 million ~~(0.5%)~~ in the first ~~nine~~six months of ~~2020~~2021 as compared to ~~the same periods in 2019. The~~2020. These increases reflected higher utility margin (operating revenue less cost of sales), and increased income tax benefits from the impacts of ratemaking as well as higher production tax ~~credit benefits driven~~credits recognized on new wind-powered generating facilities placed in-service. The earnings increases were partially offset by ~~repowered wind projects placed in-service~~higher operating expenses, including increased depreciation expense from the impacts of a deprecation study effective January 1, 2021, and ~~higher~~lower allowances for equity and borrowed funds used during ~~construction,~~construction.

PacifiCorp’s utility margin was $857 million in the second quarter and $1.7 billion in the first six months of 2021, increases of $96 million and $125 million, respectively, from the comparable periods in 2020. These increases reflected higher retail revenue from a 5.7% year-to-date increase in customer volumes and higher wholesale and other revenue, partially offset by higher ~~operating expenses~~thermal generation and ~~interest expense. The increases in operating expenses were largely~~purchased power costs. Retail customer volumes increased due to ~~costs associated with a settlement agreement and wildfires.~~

~~Utility margin was $980 million in~~higher customer usage, the third quarter and $2.5 billion in the first nine months of 2020, increases of $77 million and $50 million, respectively, compared to 2019. The increases reflected higher wholesale revenue and lower coal-fueled and natural gas-fueled generation costs, partially offset by lower retail revenue derived from a 1.8% year-to-date decline in customer volumes due to thefavorable impacts of ~~COVID-19, partly offset by~~weather and an increase in the average number of ~~customers and the favorable impacts of weather.~~

MEC operates a regulated electric and natural gas utility primarily in Iowa and Illinois. After-tax earnings increased ~~$58~~$3 million ~~(20.8%)~~ in the ~~third~~second quarter and ~~$73~~decreased $3 million ~~(11.7%)~~ in the first ~~nine~~six months of ~~2020~~2021 compared to ~~2019. The increases~~2020. These changes reflected higher electric utility margin and increased income tax benefits, ~~primarily from~~as well as higher operating expenses. The increases in operating expenses included incremental costs associated with additional wind-powered generating facilities placed in-service, as well as higher electric and natural gas distribution costs. The income tax benefit increases were mainly due to higher production tax credits recognized from higher wind-powered generation, driven primarily by ~~repowered and~~ new wind projects placed in-service, ~~and from higher~~partially offset by the impacts of ratemaking.

MEC’s electric utility margin partially offset by higher operating expenses, excluding energy efficiency program costs (substantially offset in revenues), and lower allowances for equity and borrowed funds used during construction. The increases in operating expenses were largely due to increased storm restoration costs in 2020 and wind projects placed in-service in 2019.

~~Electric utility margin, excluding energy efficiency program revenue, increased $11 million to $603~~was $483 million in the ~~third~~second quarter and $7$877 million ~~to $1.4 billion~~ in the first ~~nine~~six months of ~~2020 compared to 2019. The year-to-date electric utility margin increase was~~2021, increases of 8% and 5%, respectively, versus 2020. These increases were attributable to higher operating revenue from ~~a 1.1% increase in~~wholesale and retail customer volumes, ~~and lower~~partially offset by higher thermal generation and purchased power ~~costs, partially offset by lower wholesale revenue and price impacts from changes in sales mix.

NV Energy operates regulated electric and natural gas utilities in Nevada. After-tax earnings increased ~~$43~~$2 million ~~(20.9%)~~ in the ~~third~~second quarter and ~~$51~~$16 million ~~(16.1%)~~ in the first ~~nine~~six months of ~~2020~~2021 compared to ~~the corresponding 2019 periods.

These increases reflected ~~higher electric utility margin, higher other income (year-to-date only)~~lower interest expense and lower income tax expense from the ~~favorable~~ impacts of ratemaking, partially offset by lower electric utility margin and higher operating expenses. The increases in operating expenses were mainly due to higher ~~earnings sharing accruals at Nevada Power Company and higher~~ depreciation expense from additional plant placed ~~in-service.~~in-service, partially offset by lower plant operations and maintenance costs.

~~Electric~~NV Energy’s electric utility margin ~~increased $68 million to $660~~was $402 million in the ~~third~~second quarter and ~~$80~~$707 million ~~to $1.4 billion~~ in the first ~~nine~~six months of ~~2020~~2021, decreases of 1% and 3%, respectively, compared to ~~2019.~~2020. These ~~increases~~decreases were primarily due to ~~higher~~lower operating revenue from lower base tariff general rates at Nevada Power Company, partially offset by a ~~0.4% year-to-date~~4.4% increase in electric retail customer volumes ~~including distribution-only service customers, and~~for the first six months of 2021, price impacts from changes in sales ~~mix.~~mix and an increase in the average number of customers. The increase in ~~year-to-date~~ electric retail customer volumes was primarily due to the impacts from COVID-19 recovery and the favorable impacts of ~~weather, partially offset by the impacts of COVID-19.~~

After-tax earnings decreased $11 million (29.7%) in the third quarter and $9 million (5.0%) in the first nine months of 2020 as compared to 2019. The earnings decreases reflected higher income tax expense, in large part from a change in the United Kingdom corporate income tax rate, and higher distribution-related operating expenses, partially offset by higher other income. The year-to-date decrease was also partially offset by lower interest expense.

After-tax earnings increased $12 million (18.2%) in the third quarter and $26 million (8.8%) in the first nine months of 2020 compared to the same periods in 2019. These increases were primarily due to higher transportation revenue and the favorable impact of a rate case settlement at Northern Natural Gas, partially offset by higher operating expenses. The increase in the first nine months was further offset by increased depreciation, lower storage revenue and higher interest expense.weather.

~~After-tax~~Northern Powergrid after-tax earnings decreased $84 million in the ~~third~~second quarter and $67 million in the first six months of 2021 as compared to 2020. Earnings in each period of 2021 included deferred income tax expense of $109 million related to the enactment in the second quarter of ~~2020 declined $12 million (5.5%) compared~~an increase in the United Kingdom corporate income tax rate from 19% to ~~2019.~~25%, effective April 1, 2023. The decrease reflected the effects of favorable regulatory decisions received in 2019 at AltaLink, L.P. as well as lower operating revenue and higher operating expenses from renewable energy projects in 2020. Theearnings decreases were partially offset by higher distribution revenue, mainly from increased tariff rates and units distributed and from favorable foreign currency exchange rate movements in 2021.

Natural gas pipelines after-tax earnings increased $36 million in the second quarter and $240 million in the first six months of 2021 compared to 2020. Earnings in 2021 from BHE GT&S were $66 million in the second quarter and $173 million in the first six months. In addition, year-to-date earnings increased from the effects of higher margins on natural gas sales and higher transportation revenue at Northern Natural Gas, largely due to the favorable impacts on demand from the February 2021 winter storms.

Other energy businesses after-tax earnings increased $45 million in the second quarter and decreased $29 million in the first six months of 2021 compared to 2020. The second quarter earnings increase was primarily due to income tax benefits from renewable wind tax equity investments, largely from projects reaching commercial ~~operation.~~

~~After-tax~~operation, and higher operating revenue from owned solar projects. The decrease in year-to-date earnings ~~in the first nine months of 2020 increased $59 million (12.6%) compared to 2019. The increase~~ was primarily due to a decline in wind tax equity investment earnings of $58 million, partially offset by higher operating revenue from owned renewable energy projects. The decrease in wind tax equity investment earnings was primarily due to increased losses from preexisting tax equity investments of $134 million, largely attributable to the ~~aforementioned~~February 2021 winter storms, partially offset by increased income tax benefits from ~~renewable wind tax equity investments, partially offset by lower operating revenue and higher operating expenses from renewable energy projects.~~projects reaching commercial operation over the past twelve months.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Our manufacturing group includes a variety of industrial, building and consumer products businesses. A summary of revenues and pre-tax earnings of our manufacturing operations follows (dollars in millions).

The industrial products group includes specialty chemicals (The Lubrizol Corporation (“Lubrizol”)), complex metal products for aerospace, power and general industrial markets (Precision Castparts Corp. (“PCC”)), metal cutting tools/systems (IMC International Metalworking Companies (“IMC”)), Marmon, which consists of more than 100 autonomous manufacturing and service businesses, including equipment leasing for the rail, intermodal tank container and mobile crane industries, which are internally aggregated into sectors (or “groups”). The industrial products group also includes equipment and systems for the livestock and agricultural industries (CTB ~~International (“CTB”))~~International), and a variety of industrial products for diverse markets ~~(Marmon, Scott~~(Scott Fetzer and LiquidPower Specialty ~~Products (“LSPI”))~~Products). ~~Marmon includes UTLX Company (“UTLX”), which provides various~~

Revenues of the industrial products group in 2021 increased $1.4 billion (24.1%) from the second quarter and ~~services (including equipment leasing)~~$711 million (5.4%) over the first six months of 2020. Pre-tax earnings in 2021 increased $707 million (132%) from the second quarter and $543 million (29.5%) from the first six months of 2020. Pre-tax earnings as a percentage of revenues for the ~~rail~~group were 17.2% for the first six months of 2021 compared to 14.0% in 2020. Results in 2020 were more significantly affected by the COVID-19 pandemic.

PCC’s revenues were $1.6 billion in the second quarter and ~~mobile crane industries.~~$3.2 billion in the first six months of 2021, decreases of $156 million (8.8%) and $1.0 billion (24.7%), respectively, compared to 2020. Historically, PCC has derived significant revenues and earnings from aerospace products. The COVID-19 pandemic contributed to material declines in commercial air travel and aircraft production in 2020. While air travel in the U.S. is increasing in 2021, we do not expect significant increases in PCC’s aerospace demand to occur in the near term due to the inventory levels currently within the industry supply chain. Consequently, we anticipate PCC’s revenues and earnings in 2021 will be below pre-pandemic levels.

PCC’s pre-tax earnings increased $361 million in the second quarter and $228 million in the first six months of 2021 compared to 2020. The increases reflect the aggressive actions taken by management to resize and restructure operations.

Lubrizol’s revenues were approximately $1.7 billion in the second quarter and $3.35 billion in the first six months of 2021, increases of 28.0% in the second quarter and 15.3% in the first six months compared to 2020. The increases were attributable to higher volumes and favorable foreign currency translation effects. Despite an increase in sales and volume compared to the prior year, the Additives product line was affected by severe winter storms in February 2021, which caused the temporary shut-down of several U.S. facilities and negatively impacted sales.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Lubrizol’s pre-tax earnings decreased 17.4% in the second quarter and 15.0% in the first six months of 2021 compared to 2020. Earnings in the second quarter of 2021 included property losses, asset impairment charges and containment and response costs of approximately $160 million in connection with a fire at its Chemtool facility in Rockton, Illinois in June 2021. Earnings in 2021 were also negatively impacted by the weather-related temporary shut-down of Additives facilities in the U.S. in the first quarter due to lost sales and various incremental and non-recurring manufacturing and other operating costs. The comparative decline for the first six months was partially offset by increased earnings from the Advanced Materials business group.

Marmon’s revenues were $2.5 billion in the second quarter and $4.6 billion in the first six months of 2021, increases of $809 million (47.6%) and $899 million (24.3%), respectively, compared to 2020. The revenue increases were primarily due to higher metal prices in the Electrical, Metal Services and Plumbing & Refrigeration groups, higher volumes in most of Marmon’s business groups, particularly those serving the construction, automotive, heavy duty truck and trailer OEM markets and restaurant markets, and from favorable foreign currency translation effects. These increases were partially offset by lower revenues in the Rail & Leasing group from lower railcar repair volumes, leased fleet utilization, and lease renewal rates and from the impact of divestitures and business closures in the Water Technologies and Retail Solutions groups.

Marmon’s pre-tax earnings in 2021 increased $179 million (80.0%) in the second quarter and $162 million (30.9%) in the first six months compared to 2020. Earnings in the first six months of 2021 reflected higher earnings across most business groups, favorable currency translation effects and lower restructuring costs, partially offset by lower earnings from the Rail & Leasing and Water Technologies groups.

IMC’s revenues were $915 million in the second quarter and $1.8 billion in the first six months of 2021, increases of 43.6% in the second quarter and 21.7% in the first six months compared to 2020. Revenues in the first six months of 2021 reflected improving business conditions in most geographic regions and favorable foreign currency translation effects. IMC’s pre-tax earnings increased 136.6% in the second quarter and 65.6% in the first six months of 2021 versus 2020, primarily attributable to the favorable effects of higher customer demand, which improved manufacturing efficiencies, and also from the effects of other operating cost management saving initiatives and foreign currency translation.

The building products group includes ~~homebuilding~~manufactured and ~~manufactured housing finance~~site-built construction and related lending and financial services (Clayton Homes), flooring (Shaw), insulation, roofing and engineered products (Johns Manville), bricks and masonry products (Acme Building Brands), paint and coatings (Benjamin Moore) and residential and commercial construction and engineering products and systems (MiTek).

Revenues of the building products group increased $1.4 billion (28.9%) in the second quarter and $2.2 billion (22.4%) in the first six months of 2021 compared to 2020. Pre-tax earnings increased $277 million (39.8%) in the second quarter and $480 million (38.0%) in the first six months over 2020. Pre-tax earnings as a percentage of revenues were 14.5% in the first six months of 2021, an increase of 1.6 percentage points over 2020. Residential housing construction in the U.S. was strong during 2020 and these conditions continued through the first six months of 2021. However, the effects of strong demand and supply chain disruptions contributed to significant cost increases for key materials and products used by our businesses, including lumber, steel, copper, petrochemical-based materials, energy, freight and fixtures, necessitating higher sales prices.

Clayton Homes’ revenues were approximately $2.7 billion in the second quarter and $5.0 billion in the first six months of 2021, increases of $639 million (31.2%) and $1.2 billion (31.1%), respectively, compared to 2020. Revenues from home sales increased $1.1 billion (37%) in the first six months of 2021, reflecting a net increase in units sold, increased revenue per home sold and changes in sales mix. Unit sales of site-built homes increased 38% in the first six months of 2021, while factory-built manufactured home unit sales increased 5%. Financial services revenues, which include mortgage origination and services, insurance and interest income from lending activities, increased 13% in the first six months of 2021 compared to 2020. Loan balances, net of allowances for credit losses, were approximately $17.8 billion as of June 30, 2021, an increase of $738 million compared to December 31, 2020.

Pre-tax earnings of Clayton Homes were $456 million in the second quarter and $848 million in the first six months of 2021, increases of $138 million (43.1%) and $328 million (63.0%), respectively, compared to 2020. Earnings in the first six months of 2021 reflected higher earnings from home sales, mortgage originations, net interest income and a decline of $85 million in provisions for expected credit losses. The provisions for expected credit losses in the first six months of 2020 were unusually high and included provisions for the expected impact of the COVID-19 pandemic.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Aggregate revenues of our other building products businesses were approximately $3.7 billion in the second quarter and $7.0 billion in the first six months of 2021, increases of 27.2% and 17.0%, respectively, versus 2020. The increases were primarily due to higher volumes for paint and coatings, residential flooring, engineered products and other building systems and favorable foreign currency translation effects.

Pre-tax earnings of the other building products businesses were $517 million in the second quarter and $895 million in the first six months of 2021, increases of 37.2% and 20.5%, respectively, over 2020. The increases were primarily attributable to the increases in revenues and ongoing operating cost control efforts, partly offset by cost increases related to the constrained supply and availability of certain products and materials and shipping and freight services, attributable to the ongoing effects of supply chain disruptions and the impact of severe winter storms in 2021.

The consumer products group includes leisure vehicles (Forest River), several apparel and footwear operations (including Fruit of the Loom, Garan, Fechheimer, H.H. Brown Shoe Group and Brooks Sports) and high-performance ~~alkaline~~ batteries (Duracell). This group also includes custom picture framing products (Larson Juhl) and jewelry products (Richline). ~~A summary of~~

Consumer products revenues ~~and pre-tax earnings of our manufacturing operations follows (in millions).~~

~~Revenues of the industrial products group were $6.2~~increased approximately $1.5 billion (68.0%) in the ~~third~~second quarter and ~~$19.3~~$2.3 billion (45.9%) in the first ~~nine~~six months of ~~2020, decreases of 20.0%~~2021 compared to 2020. Pre-tax earnings increased $331 million (197%) in the ~~third~~second quarter and ~~17.0%~~$617 million (152%) in the first ~~nine months from comparable 2019 periods. Pre-tax earnings of the group were $940 million in the third quarter and $2.8 billion in the first nine~~six months of ~~2020, declines of 35.6% in the third quarter and 37.4% in the first nine months compared to 2019.~~2021 versus 2020. Pre-tax earnings as a percentage of revenues ~~for the group were 14.4%~~increased 5.8 percentage points to 13.8% in the first ~~nine~~six months of ~~2020~~2021 compared to ~~19.1% in 2019.~~2020. Revenues ~~and earnings were generally lower across each of our industrial products businesses.~~

~~PCC’s revenues were $1.5 billion in the third quarter and $5.7 billion~~ in the first ~~nine~~six months of ~~2020, decreases~~2021 increased significantly at several of 41.4% from the third quarter and 26.7% from the first nine months of 2019. Since March of 2020, the COVID-19 pandemic contributed to material declines in commercial air travel and aircraft production. Airlines responded to the pandemic by delaying delivery of aircraft orders or, in some cases, cancelling aircraft orders, resulting in significant reductions in build rates by aircraft manufacturers and significant inventory reduction initiatives being implemented by PCC’s customers. Further, Boeing’s ongoing 737 MAX aircraft production issues have contributed to the declines in aerospace product sales in 2020. These factors resulted in significant declines in demand for PCC’s aerospace products in 2020.

PCC’s pre-tax earnings in 2020 declined 80% in the third quarter and 70% in the first nine months as compared to 2019. These decreases reflected the declines in aerospace products sales, which contributed to reduced manufacturing efficiencies. PCC management continues to undertake aggressive restructuring actions to resize operations in response to reduced expected volumes in aerospace markets. During the first nine months of 2020, PCC significantly reduced its worldwide workforce and expectsour businesses that by the end of 2020, its workforce will be about 40% lower than at the end of 2019. PCC recorded charges for restructuring and inventory and fixed asset write-downs of approximately $300 million in the first nine months of 2020. Although earnings as a percentage of revenues are expected to continue to be negatively impacted through 2020 due to inefficiencies associated with aligning operations to reduced aircraft build rates, management expects the actions being taken will ultimately improve operations and increase operating margins from the current depressed levels.

~~Lubrizol’s revenues~~ were $1.5 billion in the third quarter and $4.4 billion in the first nine months of 2020, decreases of 8.7% from the third quarter and 12.5% from the first nine months of 2019. The declines were primarily attributable to lower volumes resulting from the worldwide economic impacts of COVID-19 and the effects of a fire at an additives manufacturing, blending and storage facility in Rouen, France at the end of the third quarter of 2019. While the Rouen operations were well below historical levels through the first nine months of 2020, production capacities are now substantially restored. Lubrizol’s consolidated volume declined 8.3% in the third quarter and 13.0% in the first nine months of 2020 compared to 2019, reflecting declines in the Additives and Engineered Materials product lines, partly offset by higher volumes in Life Science products.

~~Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations~~

Lubrizol’s pre-tax earnings increased 11.2% in the third quarter and decreased 14.7% in the first nine months of 2020 compared to the same periods in 2019. The comparative increase in the third quarter reflected the effects of lower raw material costs and operating expenses more than offsetting lower sales volumes and average selling prices, as the negative effects from the Rouen fire were largely offset by insurance recoveries. The decline for the first nine months was primarily attributable to lower sales volumes, the impact of the Rouen fire, lower average selling prices and effects from foreign currency translation. These negative impacts were partially offset by lower average raw material costs and lower operating expenses.

Marmon’s revenues were $2.0 billion in the third quarter and $5.7 billion in the first nine months of 2020, decreases of 6.2% from the third quarter and 9.4% from the first nine months of 2019. In the third quarter of 2020, excluding acquisitions, revenues decreased in almost all of Marmon’s sectors due to lower volumes, primarily attributable to the economic effects of the COVID-19 pandemic, with the largest effects experienced in the Transportation Products and Foodservice Technologies sectors. Additionally, revenues in the first nine months of 2020 decreased due to lower metal prices in the Electrical, Metals Services and Plumbing & Refrigeration sectors and the effect of 2019 divestitures. The drastic declines in oil prices in 2020 also adversely affected volumes and revenues in the Crane, Electrical, Water and Rail & Leasing sectors.

Marmon’s pre-tax earnings decreased 19.3% in the third quarter and 18.1% in the first nine months of 2020 compared to the same periods in 2019. The decreases reflected the declines in revenues, increased restructuring charges and lower interest income. We expect additional restructuring initiatives through the end of 2020 in response to the lower product demand, particularly in the sectors mostseverely impacted by the ~~COVID-19 pandemic.~~

IMC’s revenues were $699 million in the third quarter and $2.2 billion in the first nine months of 2020, decreases of 17.8% from the third quarter and 16.3% from the first nine months of 2019. The revenue declines were attributable to the negative economic effects from the COVID-19 pandemic ~~and unfavorable foreign currency translation effects~~ in the first half of ~~2020, partly offset by the effects of business acquisitions over the past year. IMC’s pre-tax earnings declined 32.3% in the third quarter and 35.9%~~2020.

Revenues from Forest River increased $1.3 billion (59%) in the first ~~nine~~six months of ~~2020~~2021 compared to ~~the same periods in 2019. The earnings declines were primarily due to the declines in~~2020, driven by increased unit sales for recreational vehicles. Apparel and ~~changes in sales mix.~~

~~Revenues of the building products group were $5.7 billion in the third quarter and $15.5 billion~~footwear revenues increased 46.6% in the first ~~nine~~six months of 2020, increases of $391 million (7.4%) from the third quarter and $285 million (1.9%) from the first nine months of 2019. Pre-tax earnings of the group were $825 million in the third quarter and $2.1 billion in the first nine months of 2020, increases of 18.5% from the third quarter and 9.7% from the first nine months of 2019. Pre-tax earnings as percentages of revenues were 13.5% in the first nine months of 20202021 compared to ~~12.5%~~2020, reflecting significant increases in ~~the first nine months of 2019.~~

~~Clayton Homes’ revenues were $2.3 billion~~unit sales, attributable in ~~the third quarter and $6.1 billion in the first nine months of 2020, increases of 22.4% over the third quarter and 14.7% over the first nine months of 2019.~~part to inventory restocking by certain customers, as well as from increased consumer demand. The comparative increases ~~were primarily due to increases~~ in home sales of 24.6% in the third quarter and 15.5% in the first nine months, reflecting a net increase in units sold and changes in sales mix. Unit sales of site-built homes increased 29% in the first nine months of 2020, while manufactured home unit sales increased 1%. Financial services revenues, which include mortgage services, insurance and interest income from lending activities, increased 15.7% in the third quarter and 12.5% in the first nine months of 2020 compared to 2019. Loan balances, net of allowances for credit losses, were $16.4 billion as of September 30, 2020 compared to $15.9 billion as of December 31, 2019.

Pre-tax earnings of Clayton Homes were $339 million in the third quarter and $859 million in the first nine months of 2020, increases of 24.7% in the third quarter and 11.7% in the first nine months compared to the same periods in 2019. The earnings increases reflected higher earnings from home building, increased interest income, lower interest expense and higher earnings from mortgage services, partly offset by increased provisions for credit losses and insurance losses. Although loan delinquency rates at the end of September 2020 were below those at the end of September 2019, the credit loss provisions in 2020 reflect expected credit losses, including the estimated impacts on the economy and unemployment rates arising from the COVID-19 pandemic.

Aggregate revenues of our other building products businesses were $3.4 billion in the third quarter and $9.4 billion in the first nine months of 2020, decreases of 1.0% in the third quarter and 5.1% in the first nine months compared to the same periods in 2019. The revenue decreases reflected lower volumes in certain commercial and industrial markets attributable to the negative effects of the COVID-19 pandemic, partly offset by increased paint and coatings volumes from a new agreement with Ace Hardware Stores and increased volumes in the residential markets.

Pre-tax earnings of the other building products businesses were $486 million in the third quarter and $1.2 billion in the first nine months of 2020, increases of 14.8% from the third quarter and 8.3% from the first nine months of 2019. The earnings increases reflected the effects of lower average input costs, operating cost containment efforts and lower facilities closure costs.

~~Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations~~

Consumer products revenues were $3.3 billion in the third quarter and $8.4 billion in the first nine months of 2020, an increase of 14.7% in the third quarter and a decrease of 3.0% in the first nine months compared to the same periods in 2019. Forest River sales increased 38.5% in the third quarter and 2.4% in the first nine months of 2020 as compared to the same periods in 2019. The increase in the third quarter was attributable to a significant increase in recreational vehicle unit sales and changes in sales mix.

Apparel and footwear sales in the third quarter of 2020 were relatively unchanged from the third quarter of 2019 and decreased 10.9% in the first nine months as compared to 2019. Sales volumes in the first half of 2020, particularly in the second quarter, reflected the negative effects of the COVID-19 pandemic, which included retail store closures, reduced or cancelled orders and pandemic-related disruptions at certain of our manufacturing facilities. Apparel and footwear sales in the third quarter of 2020 exceeded the second quarter of 2020 by 59%, attributable to a higher consumer demand and from retail customers restocking their inventories. Brooks Sports year-to-date revenues in 2020 were higher, partly attributable to the effect of lower sales in the first nine months of 2019 caused by product shipping delays at a new distribution facility. Revenues from Duracell in the first nine months of 2020 also increased over 2019.

~~Consumer products~~ pre-tax earnings were ~~$490 million in~~driven by the ~~third quarter and $896 million in the first nine months of 2020,~~revenue increases of 48.5% in the third quarter and 4.2% in the first nine months compared to 2019. Pre-tax earnings as a percentage of revenues for the first nine months were 10.6% in 2020 and 9.9% in 2019. The increase in pre-tax earnings for the third quarter was primarily attributable to Forest River and Duracell, and to a lesser extent from apparel and footwear. Earnings in the first nine months of 2020 included lower earnings from apparel and footwear products and increased earnings from Duracell. Earnings from Forest River, ~~were relatively unchanged in~~Brooks Sports, Duracell and the ~~first nine months of 2020 compared~~apparel businesses, as well as lower inventory obsolescence allowances. Our consumer products businesses are also experiencing cost increases attributable to ~~2019.~~supply chain disruptions.

Our service business group offers ~~fractional~~shared ownership programs for general aviation aircraft (NetJets) and ~~professional aviation~~high technology training products and services ~~and flight simulation products~~to operators of aircraft (FlightSafety). We also distribute electronic components (TTI), franchise and service a network of quick service restaurants (Dairy Queen) and offer third party logistics services that primarily serve the petroleum and chemical industries (Charter Brokerage). Other service businesses include transportation equipment leasing (XTRA) and furniture leasing (CORT), electronic news distribution, multimedia and regulatory filings (Business Wire), and the operation of a television station in Miami, Florida (WPLG) ~~and until the time of their sale on March 16, 2020, the publishing of newspapers.~~.

Service group revenues ~~were $3.1 billion~~increased 49.3% in the ~~third~~second quarter and ~~$9.1 billion~~25.9% in the first ~~nine~~six months of ~~2020, decreases of 8.2% in the third quarter and 10.8% in the first nine months as~~2021 compared to 2019. The aggregate revenues of NetJets and FlightSafety declined 10.8% in the third quarter and 14.3% for the first nine months of 2020, reflecting lower demand for aviation services as a consequence of the COVID-19 pandemic. In addition, TTI’s revenues increased 2.4% in the third quarter and decreased 1.2% in the first nine months of 2020 as compared with 2019. The comparative revenue declines in 2020 also included a year-to-date decline of 29.2% at CORT, as well as the effects of the disposition of the newspaper operations in March.

2020. Pre-tax earnings ~~of the service group were $470~~increased $467 million ~~in the third quarter and $1.2 billion in the first nine months of 2020, an increase of $19 million (4.2%~~(179.6%) in the ~~third~~second quarter and ~~a decrease of $270~~$632 million ~~(18.9%~~(92.3%) in the first ~~nine~~six months ~~compared to 2019.~~of 2021 versus 2020.

Revenues from TTI increased 52.4% in the second quarter and 38.7% in the first six months of 2021 versus 2020. The increases reflected accelerating demand across all significant markets within the electronic components industry as industry participants attempt to maintain adequate inventories in response to high demand for components in end products and supply chain disruptions. Revenues from aviation services (NetJets and FlightSafety) increased 56.0% in the second quarter and 22.4% in the first six months of 2021 over low 2020 ~~was~~levels, primarily due to higher training hours and significantly higher customer flight hours.

Earnings at most of our service businesses increased significantly in the second quarter and first six months of 2021 compared to 2020, with the largest increases from TTI and the aviation services businesses. The increases in the aggregate earnings from NetJets and FlightSafety were primarily attributable to ~~FlightSafety, NetJets, TTI~~improved operating margins from changes in business mix, increased operating efficiencies and ~~CORT.~~the effects of past restructuring efforts. TTI’s earnings ~~decline reflected lower average gross margin rates,~~increases were primarily attributable to ~~sluggish~~the increases in sales ~~volumes in certain markets~~ and sales price pressures deriving from ample inventory availability within the industry. The declines at NetJets, FlightSafety and CORT were due to lower customer demand for services and increased asset impairment and restructuring charges in the aviation services businesses.

The spread of COVID-19 throughout the U.S. resulted in the temporary closures or restricted operations at some~~2020. Operating results of our ~~retail store operations during~~retailing businesses were severely impacted by the pandemic beginning in March of 2020 and ~~significantly lower sales~~continuing through the second quarter of 2020. Over the second half of 2020 and continuing through the first six months of 2021, revenues and pre-tax earnings of these businesses increased, and in certain instances increased to levels exceeding those in pre-pandemic periods, despite ongoing supply chain disruptions.

BHA’s revenues in the first half of the year. The severity and duration of the effects on our operations from the pandemic have varied widely. Sales volumes increased and operating results improved beginning in the latter part of the second quarter as our operations slowly reopened.

~~BHA’s revenues decreased 2.5% in the third quarter and 4.9% in the first nine~~six months of 2021 increased 29.4% from 2020, ~~compared~~primarily due to ~~the same periods in 2019.

McLane operates a wholesale distribution business that provides grocery and non-food consumer products to retailers and convenience stores (“grocery”) and to restaurants (“foodservice”). McLane also operates businesses that are wholesale distributors of distilled spirits, wine and beer (“beverage”). The grocery and foodservice businesses generate high sales and very low profit margins. These businesses have several significant customers, including Walmart, 7-Eleven, Yum! Brands and others. Grocery sales ~~comprised~~typically comprise about ~~2/3~~two-thirds of McLane’s consolidated sales ~~in the first nine months of 2020~~ with foodservice comprising ~~most~~much of the remainder. A curtailment of purchasing by any of its significant customers could have an adverse impact on periodic revenues and earnings.

~~Revenues were $12.0 billion in the third quarter~~ The grocery and $35.1 billion in the first nine months of 2020, decreases of 4.5% in the third quarter and 5.7% in the first nine months compared to 2019. Revenues in the third quarter of 2020 decreased 4.7% in the grocery business (5.4% year-to-date) and 5.2% in the foodservice business (7.7% year-to-date) as compared to 2019. The declines were attributable to COVID-19 related restaurant closures (particularly in the casual dining category) in the foodservice business and lower sales in certain product categories within the grocery business.

Pre-tax earnings increased $46 million (92.0%) in the third quarter and decreased $15 million (6.8%) in the first nine months of 2020 as compared to 2019. The earnings increase in the third quarter reflected ongoing operating expense management efforts and a slight increase in the overall gross margin rate, partly offset by the effects of lower sales. The earnings decrease in the first nine months of 2020 included charges of $23 million for credit and inventory losses in the foodservice operations and the impact of lower sales. McLane continuesbusinesses continue to operate in an intensely competitive business ~~environment, which is~~environment.

Revenues increased $1.1 billion (9.6%) in the second quarter and $878 million (3.8%) in the first six months of 2021 compared to 2020. Revenues from the grocery business were relatively unchanged in the first six months of 2021, while revenues from the foodservice and beverage businesses increased 9.9% and 21.7%, respectively, compared to the first six months of 2020. The foodservice business was negatively ~~affecting its current operating results.~~

A summary of investment and derivative gains/losses follows (dollars in millions).

~~We are required to include the unrealized~~Unrealized gains and losses arising from changes in market prices of investments in equity securities are included in our reported earnings, which significantly increases the volatility of our periodic net earnings due to the magnitude of our equity securities portfolio and the inherent volatility of equity securities prices.

Taxable investment gains on equity securities sold, which is generally the difference between sales proceeds and the original cost basis of the securities sold, were ~~$3.9 billion~~$228 million in the ~~third quarter and $0.7 billion in the first nine months. In 2019, taxable investment gains on equity securities sold were $0.6 billion in the third~~second quarter and $2.0 billion in the first ~~nine months.~~six months of 2021. Taxable investment losses on equity securities were $4.5 billion in the second quarter and $3.3 billion in the first six months of 2020.

~~Investment gains/losses from periodic changes in securities prices will continue to cause significant volatility in our consolidated earnings.~~ We believe that investment gains/losses, whether realized from sales or unrealized from changes in market prices, are often meaningless in terms of understanding our reported consolidated earnings or evaluating our periodic economic performance. We continue to believe ~~that~~ the ~~amount of~~ investment gains/losses ~~included~~recorded in earnings in any given period has little analytical or predictive value.

Derivative contract gains/losses include the changes in fair value of our equity index put option contract liabilities, which relate to contracts that were originated prior to March 2008. ~~Substantially all remaining contracts will expire by February 2023.~~ The periodic changes in the fair values of these liabilities are recorded in earnings and can be significant due to the volatility of market prices in the underlying equity markets. As of ~~September~~June 30, ~~2020,~~2021, the intrinsic value of our equity index put option contracts was ~~approximately $1.2 billion~~$72 million and our recorded liability at fair value was ~~$1.5 billion.~~$355 million.

After-tax equity method earnings include ~~Berkshire’s~~our proportionate share of earnings attributable to our investments in Kraft Heinz, Pilot, Berkadia and Electric Transmission of Texas. Our after-tax earnings from Kraft Heinz were $20 million for the second quarter and $155 million for the first six months of 2021. Our Kraft Heinz investment produced after-tax ~~earnings~~losses of ~~$142~~$297 million for the ~~third~~second quarter and ~~an after-tax loss of $56~~$198 million for the first ~~nine~~six months of ~~2020.

As discussed in Note 5 to the accompanying Consolidated Financial Statements, financial results of Kraft Heinz for the first and second quarters of 2019 were not available to us until the third quarter. Accordingly, our consolidated statements of earnings for the third quarter of 2019 included our share of Kraft Heinz’s earnings for the first nine months, or $377 million, which included $214 million attributable toassociated with goodwill and intangible asset impairment charges recorded by Kraft Heinz.

After-tax acquisition accounting expenses include charges arising from the application of the acquisition method in connection with certain of Berkshire’s past business acquisitions. Such charges arise primarily from the amortization of intangible assets recorded in connection with those business acquisitions. Goodwill and intangible asset impairments in the second quarter and first ~~nine~~six months of 2020 included ~~charges of~~ $9.8 billion attributable to impairments of goodwill and certain identifiable intangible assets ~~that were~~ recorded in connection with our acquisition of PCC in 2016. ~~See Critical Accounting Policies on page 46 for additional details.~~

Foreign currency exchange rate gains and losses pertain to ~~non-U.S. Dollar~~Berkshire’s Euro and Japanese Yen denominated debt ~~issued by Berkshire~~ and ~~BHFC. As of September 30, 2020, outstanding borrowings included senior notes of €6.85 billion par, ¥625.5 billion par and £1.75 billion par.~~BHFC’s Great Britain Pound denominated debt. Changes in foreign currency exchange rates produce ~~non-cash~~ unrealized gains and losses from the periodic revaluation of these liabilities into U.S. Dollars. The gains and losses recorded in any given period can be significant due to the magnitude of the borrowings and the inherent volatility in foreign currency exchange rates.

The income tax expense adjustments relate to investments that we made between 2015 and 2018 in certain tax equity investment funds, which aggregated approximately $340 million. In December 2018 and during the first quarter of 2019, we learned of allegations by federal authorities of fraudulent income conduct by the sponsor of these funds and in January 2020, the principals involved in creating the investment funds plead guilty to criminal charges related to the sale of the investments. In the first quarter of 2019, we concluded it was more likely than not that the income tax benefits that we recognized prior to 2019 were not valid.

Our consolidated balance sheet continues to reflect very significant liquidity and a very strong capital base. Consolidated shareholders’ equity at ~~September~~June 30, ~~2020~~2021 was ~~$415.2~~$470 billion, ~~a decrease~~an increase of ~~$9.6~~$27.2 billion since December 31, ~~2019 and an increase of $21.7 billion since June 30,~~ 2020. Net earnings attributable to Berkshire shareholders were ~~$30.1 billion in the third quarter and $6.7~~$39.8 billion in the first ~~nine~~six months of ~~2020. Earnings~~2021 and included after-tax gains on our investments of approximately ~~$24.8 billion in the third quarter and $1.3 billion in the first nine months of 2020.~~$25.5 billion. Changes in the market prices ~~for~~of our investments in equity securities ~~since December 31, 2019 have produced exceptional~~can produce significant volatility in our earnings. ~~Our results in 2020 also included after-tax goodwill and other intangible asset impairment charges of $11.0 billion.~~

At ~~September~~June 30, ~~2020,~~2021, our insurance and other businesses held cash, cash equivalents and U.S. Treasury Bills ~~(net~~ of ~~amounts payable as of September 30 for purchases that were settled in October) of $135.2~~$140.7 billion, which included ~~$114.1~~$118.1 billion in U.S. Treasury Bills. Investments in equity and fixed maturity securities (excluding our investment in Kraft Heinz) were ~~$264.8~~$328.4 billion.

~~Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations~~

Berkshire parent company outstanding debt ~~outstanding~~ at ~~September~~June 30, ~~2020~~2021 was ~~$22.2~~$22.5 billion, ~~an increase~~a decrease of ~~$2.3 billion~~$190 million since December 31, ~~2019.~~2020. In the first ~~nine months~~quarter of ~~2020,~~2021, Berkshire repaid €550 million and $1.0 billion of maturing senior notes ~~of €1.0 billion~~ and issued ~~€1.0 billion~~€600 million of ~~0.0%~~0.5% senior notes due in ~~2025 and ¥195.5~~2041. In April 2021, Berkshire issued ¥160 billion (approximately $1.5 billion) of senior notes ~~(approximately $1.8 billion), which has~~with maturity dates ranging from 2026 to 2041 and a weighted average interest rate of ~~1.07% and maturity dates ranging from 2023 to 2060. In~~0.5%. Berkshire parent company debt maturing over the ~~first quarter of 2021, senior notes of $1.6 billion will mature.~~next twelve months is $1.1 billion.

Berkshire’s insurance and other subsidiary outstanding borrowings were ~~$16.7~~$18.1 billion at ~~September~~June 30, ~~2020,~~2021, which included senior note borrowings of BHFC, a wholly-owned financing subsidiary, of approximately ~~$11.0~~$13.1 billion. BHFC’s borrowings are used to fund a portion of loans originated and acquired by Clayton Homes and equipment held for lease by our ~~UTLX~~ railcar leasing business. In ~~the first nine months of 2020,~~January 2021, BHFC repaid ~~$350~~$750 million of maturing senior notes and issued ~~$500~~$750 million of ~~1.85%~~2.5% senior notes due in ~~2030. In October 2020,~~2051. BHFC ~~repaid $550 million of~~debt maturing over the next twelve months is $775 million. Berkshire guarantees BHFC’s senior notes ~~and issued $2.5 billion of senior notes, consisting of $750 million of 1.45% senior notes due in 2030 and $1.75 billion of 2.85% senior notes due in 2050. Berkshire guarantees~~for the full and timely payment of principal and ~~interest with respect to BHFC’s senior notes. In the first quarter~~interest.

Item 2. Management’s Discussion and Analysis of ~~2021, approximately $750 million~~Financial Condition and Results of ~~BHFC senior notes will mature.~~Operations

Our railroad, utilities and energy businesses (conducted by BNSF and BHE) maintain very large investments in capital assets (property, plant and equipment) and will regularly make significant capital expenditures in the normal course of business. Capital expenditures of these two operations in the first ~~nine~~six months of ~~2020~~2021 were ~~$7.1~~$4.1 billion and we currently forecast additional capital expenditures of approximately $3$6.2 billion over the remainder of ~~2020.~~2021.

BNSF’s outstanding debt was $23.2 billion as of September 30, 2020, relatively unchanged from December 31, 2019. In April 2020, BNSF issued $575 million of 3.05% senior unsecured debentures due in 2051. Outstanding borrowings of BHE and its subsidiaries were $45.6 billion at September 30, 2020, an increase of approximately $3.0 billion since December 31, 2019. In the first nine months of 2020, BHE and its subsidiaries issued new term debt aggregating $5.5 billion with maturity dates ranging from 2025 to 2062, repaid approximately $1.9 billion of debt and reduced short-term borrowings. Over the remainder of 2020, BHE and its subsidiaries will repay debt of approximately $640 million. On October 29, 2020, BHE issued $500 million of 1.65% senior notes due in 2031 and $1.5 billion of 2.85% senior notes due in 2051. Berkshire does not guarantee the repayment of debt issued by BNSF, BHE or any of their subsidiaries and is not committed to provide capital to support BNSF, BHE or any of their subsidiaries.

BNSF’s outstanding debt was $23.3 billion as of June 30, 2021, relatively unchanged from December 31, 2020. During the first six months of 2021, BNSF repaid $886 million of debt and issued $925 million of 3.3% debentures due in 2051. Outstanding borrowings of BHE and its subsidiaries were $51.4 billion at June 30, 2021, a decrease of $744 million since December 31, 2020. During the first six months of 2021, BHE and its subsidiaries repaid $1.7 billion of term debt, issued $550 million of 3.4% term debt due in 2051 and increased short-term borrowings by $250 million. In July ~~2020,~~2021, BHE reached a definitive agreement with Dominion Energy, Inc. (“Dominion”) to acquire substantially all of Dominion’s natural gas transmission and storage businesses. As discussed in Note 22 to the accompanying Consolidated Financial Statements, on November 1, 2020, BHE acquired certain of the Dominion businesses for $2.7 billion in cash and assumed $5.3subsidiaries issued $1.5 billion of ~~Dominion debt. The acquisition of~~term debt due in 2052 with interest rates ranging from 2.7% to 2.9%. Aggregate debt maturities for BHE and BNSF over the ~~remainder of the Dominion businesses is expected to close in early 2021.~~next twelve months approximate $1.5 billion.

Berkshire’s common stock repurchase program, ~~was~~as amended, ~~on July 17, 2018, permitting~~permits Berkshire to repurchase its Class A and Class B shares at prices below Berkshire’s intrinsic value, as conservatively determined by Warren Buffett, Berkshire’s Chairman of the Board and Chief Executive Officer, and Charlie Munger, Vice Chairman of the Board. The program allows share repurchases in the open market or through privately negotiated transactions and does not specify a maximum number of shares to be repurchased. The program is expected to continue indefinitely. We will not repurchase our stock if it reduces the total amount of Berkshire’s consolidated cash, cash equivalents and U.S. Treasury ~~Bill~~Bills holdings below ~~$20~~$30 billion. Financial strength and redundant liquidity will always be of paramount importance at Berkshire. ~~In the first nine months of 2020,~~ Berkshire paid ~~$15.7 billion, including $9.0~~$12.6 billion in the ~~third quarter,~~first six months of 2021 to repurchase shares of its Class A and B common stock.

We are party to contracts associated with ongoing business and financing activities, which will result in cash payments to counterparties in future periods. Certain obligations are included in our Consolidated Balance Sheets, such as notes payable, which require future payments on contractually specified dates and in fixed and determinable amounts. Other obligations pertaining to the acquisition of goods or services in the future are not currently reflected in the financial statements, which will be recognized in future periods as the goods are delivered or services are provided. The timing and amount of the payments under certain contracts, such as insurance and reinsurance contracts, are contingent upon the outcome of future ~~events. Actual~~events and the actual payments will likely vary, perhaps materially, from the estimated liabilities currently recorded in our Consolidated Balance Sheet.

In the first ~~nine~~six months of ~~2020,~~2021, Berkshire and certain of its subsidiaries issued ~~new~~ term ~~debt.~~debt of approximately $4.4 billion in the aggregate. Principal and interest payments associated with these ~~new term~~ borrowings are expected as follows: in ~~2020~~2021 – ~~$82~~$38 million; in ~~2021 and~~ 2022 through 2025 – ~~$472 million; in 2023 and 2024 – $1.0 billion;~~$79 million per annum; and thereafter – ~~$12.2~~$6.2 billion. ~~In October 2020, Berkshire subsidiaries issued new term debt aggregating $4.5 billion with maturities ranging from 2030 to 2051.~~

~~Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations~~

Except as otherwise disclosed in this Quarterly Report, our contractual obligations as of ~~September~~June 30, ~~2020~~2021 were, in the aggregate, not materially different from those disclosed in the “Contractual Obligations” section of “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in Berkshire’s Annual Report on Form 10-K for the year ended December 31, ~~2019.~~2020.

Certain accounting policies require us to make estimates and judgments that affect the amounts reflected in the Consolidated Financial Statements. Such estimates and judgments necessarily involve varying, and possibly significant, degrees of uncertainty. Accordingly, certain amounts recorded in the financial statements will likely be adjusted in the future based on new available information and changes in other facts and circumstances. Reference is made to “Critical Accounting Policies” discussed in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in Berkshire’s Annual Report on Form 10-K for the year ended December 31, ~~2019.~~2020.

Our Consolidated Balance Sheet as of ~~September~~June 30, ~~2020~~2021 includes estimated liabilities of $123.2 billion for unpaid losses and loss adjustment expenses from property and casualty insurance and reinsurance ~~contracts of $119.8 billion.~~contracts. Due to the inherent uncertainties in the processes of establishing these liabilities, the actual ultimate claim amounts will likely differ from the currently recorded amounts. A very small percentage change in estimates of this magnitude can result in a material effect on periodic earnings. The effects from changes in these estimates are recorded as a component of insurance losses and loss adjustment expenses in the period of the change.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Our Consolidated Balance Sheet as of ~~September~~June 30, ~~2020~~2021 included goodwill of acquired businesses of ~~$71.9~~$73.8 billion and indefinite-lived intangible assets of $18.3 billion. We evaluate these assets for impairment at least annually and we conducted our most recent annual review during the fourth quarter of ~~2019.~~2020.

Goodwill and indefinite-lived intangible asset impairment reviews include determining the estimated fair values of our reporting units and assets. The key assumptions and inputs used in such determinations may include forecasting revenues and expenses, cash flows and capital expenditures, as well as an appropriate discount rate and other inputs. Significant judgment by management is required in estimating the fair value of a reporting unit and in performing impairment tests. Due to the inherent subjectivity and uncertainty in forecasting future cash flows and earnings over long periods of time, actual results may vary materially from the forecasts.

~~In response to the adverse effects of the COVID-19 pandemic, we considered whether goodwill needed to be reevaluated for impairment.~~ As of June 30, 2020, we determined it was necessary to quantitively reevaluate goodwill for impairment for certain reporting units, and most significantly for PCC. As a result of our reviews, we recorded pre-tax goodwill impairment charges of $10.0 billion and indefinite-lived intangible asset impairment charges of $638 million in the second quarter of 2020, of which approximately $10 billion related to PCC.

Prior to the reevaluation, the carrying value of our goodwill in PCC was approximately $17 billion. Additionally, the carrying value of indefinite-lived intangible assets in PCC was approximately $14 billion. Substantially all of these amounts were recorded in connection with Berkshire’s acquisition of PCC in 2016. We believe the effects of the COVID-19 pandemic on commercial airlines and aircraft manufacturers is particularly severe. We considered a number of factors in our reevaluation, including but not limited to the announcements by airlines concerning potential future demand, employment levels and aircraft orders, announcements by manufactures on reduced aircraft production, and the actions we are taking or may take to restructure our operations to fit lower expected demand. In our judgment, the timing and extent of the recovery in the commercial airline and aerospace industries may be dependent on the development and wide-scale distribution of medicines or vaccines that effectively treat the virus. Consequently, we deemed it prudent under the prevailing circumstances to increase the discount rates and reduce our prior long-term forecasts of future cash flows for purposes of reviewing for impairments. The amounts of these adjustments were based on qualitative assessments by Berkshire.

~~As of September 30, 2020,~~2021, we concluded it is more likely than not that goodwill recorded in our Consolidated Balance Sheet was not impaired. The long-term adverse effects of the COVID-19 pandemic on certain of our reporting units may prove to be worse than we currently anticipate, and we may need to record goodwill or indefinite-lived asset impairment charges in future periods. Making estimates of the fair value of reporting units and judgments on goodwill impairments at this time are and will likely be significantly affected by assumptions on the severity, duration or long-term effects of the pandemic on ~~the~~a reporting unit’s business, which we cannot reliably predict. Consequently, any fair value estimates in such instances can be subject to wide variations. ~~The effects~~

As of the ~~COVID-19 pandemic could prove to be worse than we currently estimate for our reporting units, including reporting units where we recorded~~most recent annual goodwill impairment ~~charges~~review conducted during ~~the first nine months of 2020, and could lead us to record additional goodwill or indefinite-lived asset impairment charges in~~ the fourth quarter of ~~2020.~~

~~Item 2. Management’s Discussion and Analysis~~2020, the estimated fair values of ~~Financial Condition and Results~~certain reporting units did not exceed our carrying values by at least 20%. The most significant of ~~Operations~~

~~Critical Accounting Policies~~ ~~(Continued)~~these reporting units was Precision Castparts Corp. (“PCC”). The estimated fair value of PCC was approximately $35.5 billion, exceeding our carrying value of approximately $32.1 billion by 10.6%. Our carrying value of PCC included goodwill of approximately $7.5 billion. For the four other reporting units where estimated fair value did not exceed carrying value by at least 20%, their aggregate estimated fair value of approximately $1.5 billion exceeded our aggregate carrying value of approximately $1.4 billion by 10.0%. Our carrying value of these units included goodwill of approximately $600 million.

Information concerning new accounting pronouncements is included in Note 2 to the accompanying Consolidated Financial Statements.

Investors are cautioned that certain statements contained in this document as well as some statements in periodic press releases and some oral statements of Berkshire officials during presentations about Berkshire or its subsidiaries are “forward-looking” statements within the meaning of the Private Securities Litigation Reform Act of 1995 (the “Act”). Forward-looking statements include statements which are predictive in nature, which depend upon or refer to future events or conditions, which include words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “estimates” or similar expressions. In addition, any statements concerning future financial performance (including future revenues, earnings or growth rates), ongoing business strategies or prospects and possible future Berkshire actions, which may be provided by management, are also forward-looking statements as defined by the Act. Forward-looking statements are based on current expectations and projections about future events and are subject to risks, uncertainties and assumptions about Berkshire and its subsidiaries, economic and market factors and the industries in which we do business, among other things. These statements are not guarantees of future performance and we have no specific intention to update these statements.

Actual events and results may differ materially from those expressed or forecasted in forward-looking statements due to a number of factors. The principal risk factors that could cause our actual performance and future events and actions to differ materially from such forward-looking statements include, but are not limited to, changes in market prices of our investments in fixed maturity and equity ~~securities,~~securities; losses realized from derivative ~~contracts,~~contracts; the occurrence of one or more catastrophic events, such as an earthquake, hurricane, act of terrorism or cyber attack that causes losses insured by our insurance subsidiaries and/or losses to our business ~~operations,~~operations; the frequency and severity of epidemics, pandemics or other outbreaks, including COVID-19, that negatively affect our operating results and restrict our access to borrowed funds through the capital markets at reasonable ~~rates,~~rates; changes in laws or regulations affecting our insurance, railroad, utilities and energy and finance ~~subsidiaries,~~subsidiaries; changes in federal income tax ~~laws,~~laws; and changes in general economic and market factors that affect the prices of securities or the industries in which we do business.

Reference is made to Berkshire’s most recently issued Annual Report and in particular the “Market Risk Disclosures” included in “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” As of ~~September~~June 30, ~~2020,~~2021, there were no material changes in the market risks described in Berkshire’s Annual Report on Form 10-K for the year ended December 31, ~~2019.~~2020.

As of the end of the period covered by this Quarterly Report on Form 10-Q, the Company carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Chairman (Chief Executive Officer) and the Senior Vice President (Chief Financial Officer), of the effectiveness of the design and operation of the Company’s disclosure controls and procedures pursuant to Exchange Act Rule 13a-15. Based upon that evaluation, the Chairman (Chief Executive Officer) and the Senior Vice President (Chief Financial Officer) concluded that the Company’s disclosure controls and procedures are effective in timely alerting them to material information relating to the Company (including its consolidated subsidiaries) required to be included in the Company’s periodic SEC filings. During the quarter, there have been no significant changes in the Company’s internal control over financial reporting or in other factors that could significantly affect internal control over financial reporting.

Berkshire and its subsidiaries are parties in a variety of legal actions that routinely arise out of the normal course of business, including legal actions seeking to establish liability directly through insurance contracts or indirectly through reinsurance contracts issued by Berkshire subsidiaries. Plaintiffs occasionally seek punitive or exemplary damages. We do not believe that such normal and routine litigation will have a material effect on our consolidated financial condition or results of operations. Berkshire and certain of its subsidiaries are also involved in other kinds of legal actions, some of which assert or may assert claims or seek to impose fines and penalties. We believe that any liability that may arise as a result of other pending legal actions will not have a material effect on our consolidated financial condition or results of operations.

Our significant business risks are described in Item 1A to Form 10-K for the year ended December 31, ~~2019~~2020, to which reference is made herein. T~~hese risk factors are supplemented for the items described below~~. The risks and uncertainties we describe are not the only ones facing us. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business or operations. Any adverse effect on our business, financial condition or operating results could result in a decline in the value of our securities and the loss of all or part of your investment.

~~Epidemics, pandemics or other outbreaks, including COVID-19, could hurt our operating businesses.~~Part II Other Information

The outbreak of COVID-19 has adversely affected, and in the future it or other epidemics, pandemics or outbreaks may adversely affect, our operations, including our equity securities portfolio. This is or may be due to closures or restrictions requested or mandated by governmental authorities, disruption to supply chains and workforce, reduction of demand for our products and services, credit losses when customers and other counterparties fail to satisfy their obligations to us, and volatility in global equity securities markets, among other factors. We share most of these risks with all businesses.

~~Unfavorable general economic conditions may significantly reduce our operating earnings and impair our ability to access capital markets at a reasonable cost.~~

Our operating businesses are subject to economic conditions affecting the general economy or the specific industries in which they operate. To the extent that economic conditions in the U.S. and worldwide are depressed by the effects of COVID-19 or otherwise, one or more of our significant operations could be materially harmed. In addition, our utilities and energy businesses and our railroad business regularly utilize debt as a component of their capital structures, and depend on having access to borrowed funds through the capital markets at reasonable rates. To the extent that access to the capital markets is restricted or the cost of funding increases, these operations could be adversely affected.
