NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

September 30, 2016

Note 1. General

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

Financial information in this Quarterly Report reflects any 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. Variations in the amount and timing of investment gains/losses can cause significant variations in periodic net earnings. Investment gains/losses are recorded when investments are disposed or are other-than-temporarily impaired. In addition, changes in the fair values of liabilities associated with derivative contracts can cause significant variations in periodic net earnings.

Note 2. New accounting pronouncements

In May 2014, the FASB issued ASU 2014-09 “Revenue from Contracts with Customers.” ASU 2014-09 applies to contracts with customers, excluding, most notably, insurance and leasing contracts. ASU 2014-09 prescribes a framework in accounting for revenues from contracts within its scope, including (a) identifying the contract, (b) identifying the performance obligations under the contract, (c) determining the transaction price, (d) allocating the transaction price to the identified performance obligations and (e) recognizing revenues as the identified performance obligations are satisfied. ASU 2014-09 also prescribes additional financial statement presentations and disclosures. We currently expect to adopt ASU 2014-09 as of January 1, 2018, under the modified retrospective method where the cumulative effect is recognized at the date of initial application. Our evaluation of ASU 2014-09 is ongoing and not complete. The FASB has issued and may issue in the future, interpretative guidance, which may cause our evaluation to change. While we anticipate some changes to revenue recognition for certain customer contracts, we do not currently believe ASU 2014-09 will have a material effect on our Consolidated Financial Statements.

In May 2015, the FASB issued ASU 2015-09 “Financial Services—Insurance—Disclosures about Short-Duration Contracts,” which requires additional disclosures in annual and interim reporting periods by insurance entities regarding liabilities for unpaid claims and claim adjustment expenses, and changes in assumptions or methodologies for calculating such liabilities. ASU 2015-09 is effective for annual periods beginning after December 15, 2015 and interim periods beginning after December 15, 2016. We continue to evaluate the effect adopting this standard will have on the disclosures in our Consolidated Financial Statements.

In January 2016, the FASB issued ASU 2016-01 “Financial Instruments—Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 generally requires that equity investments (excluding equity method investments) be measured at fair value with changes in fair value recognized in net income. Under existing GAAP, changes in fair value of available-for-sale equity investments are recorded in other comprehensive income. Given the current magnitude of our equity investments, the adoption of ASU 2016-01 will likely have a significant impact on the periodic net earnings reported in our Consolidated Statement of Earnings, although it will likely not significantly impact our comprehensive income or shareholders’ equity. ASU 2016-01 is effective for annual and interim periods beginning after December 15, 2017, with the cumulative effect of the adoption made to the balance sheet as of the date of adoption. Thus, the adoption will result in a reclassification of the related accumulated unrealized appreciation currently included in accumulated other comprehensive income to retained earnings, with no impact on Berkshire shareholders’ equity.

In February 2016, the FASB issued ASU 2016-02 “Leases.” ASU 2016-02 requires a lessee to recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term, along with additional qualitative and quantitative disclosures. ASU 2016-02 is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the effect this standard will have on our Consolidated Financial Statements.

Notes to Consolidated Financial Statements (Continued)

Note 2. New accounting pronouncements (Continued)

In June 2016, the FASB issued ASU 2016-13 “Financial Instruments—Credit Losses,” which provides for the recognition and measurement at the reporting date of all expected credit losses for financial assets held at amortized cost and available-for-sale debt securities. Currently credit losses are recognized and measured when such losses become probable based on the prevailing facts and circumstances. ASU 2016-13 is effective for reporting periods beginning after December 15, 2019. We are currently evaluating the effect this standard will have on our Consolidated Financial Statements.

Note 3. Significant business acquisitions

Our long-held acquisition strategy is to acquire businesses at sensible prices that have consistent earning power, good returns on equity and able and honest management. On August 8, 2015, Berkshire entered into a definitive agreement with Precision Castparts Corp. (“PCC”) to acquire all outstanding PCC shares of common stock for $235 per share in cash. The acquisition was completed on January 29, 2016. The aggregate consideration paid was approximately $32.7 billion, which included the value of PCC shares we already owned. We funded the acquisition with a combination of existing cash balances and proceeds from a short-term credit facility.

PCC is a worldwide, diversified manufacturer of complex metal components and products. It serves the aerospace, power and general industrial markets. PCC is a market leader in manufacturing complex structural investment castings and forged components for aerospace markets, machined airframe components and highly engineered critical fasteners for aerospace applications, and in manufacturing airfoil castings for the aerospace and industrial gas turbine markets. PCC also is a leading producer of titanium and nickel superalloy melted and mill products for the aerospace, chemical processing, oil and gas and pollution control industries, and manufactures extruded seamless pipe, fittings and forgings for power generation and oil and gas applications.

In November 2014, Berkshire entered into a definitive agreement with The Procter & Gamble Company (“P&G”) to acquire the Duracell business from P&G. The transaction closed on February 29, 2016. Duracell is a leading manufacturer of high-performance alkaline batteries and is an innovator in renewable power and wireless charging technologies. Pursuant to the agreement, we received a recapitalized Duracell Company in exchange for shares of P&G common stock held by Berkshire subsidiaries which had a fair value of approximately $4.2 billion.

Financial results attributable to these business acquisitions are included in our Consolidated Financial Statements beginning on their respective acquisition dates. The acquisition date fair values of certain assets and liabilities, particularly property, plant and equipment and intangible assets, and related estimated useful lives are provisional and are subject to revision as the related valuations are completed. We expect such values will be finalized as of December 31, 2016. Goodwill from these acquisitions is not amortizable for income tax purposes. Preliminary fair values of identified assets acquired and liabilities assumed and residual goodwill of PCC and Duracell at their respective acquisition dates are summarized in the table that follows (in millions).

Note 5. Investments in equity securities

Investments in equity securities as of September 30, 2016 and December 31, 2015 are summarized based on the primary industry of the investee in the table below (in millions).

	Cost Basis		Unrealized Gains		Unrealized Losses			Fair Value
September 30, 2016 *
Banks, insurance and finance	$	19,852	$	21,695	$	(173	)	$	41,374

	$	57,518	$	46,389	$	(1,372	)	$	102,535

* Approximately 60% of the aggregate fair value was concentrated in the equity securities of four companies (American Express Company – $9.7 billion; Wells Fargo & Company – $22.1 billion; International Business Machines Corporation (“IBM”) – $12.9 billion; and The Coca-Cola Company – $16.9 billion).

	Cost Basis		Unrealized Gains		Unrealized Losses		Fair Value
December 31, 2015 *
Banks, insurance and finance	$	20,026	$	27,965	$	(21)	$	47,970
Consumer products		6,867		18,022		(1)		24,888
Commercial, industrial and other		35,417		6,785		(3,238)		38,964
	$	62,310	$	52,772	$	(3,260)	$	111,822

* Approximately 59% of the aggregate fair value was concentrated in the equity securities of four companies (American Express Company – $10.5 billion; Wells Fargo & Company – $27.2 billion; IBM – $11.2 billion; and The Coca-Cola Company – $17.2 billion).

As of September 30, 2016 and December 31, 2015, we concluded that the unrealized losses shown in the tables above were temporary. Our conclusions were based on: (a) our ability and intent to hold the securities to recovery; (b) our assessment that the underlying business and financial condition of the issuers was favorable; (c) our opinion that the relative price declines were not significant; and (d) our belief that market prices will increase to and exceed our cost. As of September 30, 2016 and December 31, 2015, unrealized losses on equity securities in a continuous unrealized loss position for more than twelve months were $995 million and $989 million, respectively.

Unrealized losses at September 30, 2016 included $941 million related to our investment in IBM common stock of which $855 million had been in a continuous unrealized loss position for more than twelve months. Unrealized losses represented 7% of our cost. IBM continues to be profitable and generate significant cash flows. We currently do not intend to dispose of our IBM common stock and we expect that the fair value of this investment will recover and ultimately exceed our cost.

During 2008, we purchased $2.1 billion of Wrigley preferred stock that was acquired pursuant to a shareholder agreement in conjunction with Mars Incorporated’s acquisition of Wrigley. Pursuant to certain put and call provisions in the shareholder agreement, up to 50% of our original investment was redeemable over a 90-day period that was scheduled to begin on October 6, 2016. On August 8, 2016, we entered into a stock purchase agreement with Mars, under which Mars agreed to acquire all of the Wrigley preferred stock for approximately $4.56 billion, which included a prorated dividend that would have otherwise been payable on October 6, 2016. The transaction was completed on September 27, 2016.

We own 3,000,000 shares of Series A Cumulative Convertible Perpetual Preferred Stock of Dow (“Dow Preferred”) with a liquidation value of $1,000 per share. Each share of the Dow Preferred is convertible into 24.201 shares of Dow common stock (equivalent to a conversion price of $41.32 per share). Dow currently has the option to cause some or all of the Dow Preferred to be converted into Dow common stock at the then applicable conversion rate, if the New York Stock Exchange closing price of its common stock exceeds $53.72 per share for any 20 trading days within a period of 30 consecutive trading days ending the day before Dow exercises its option. The Dow Preferred is entitled to dividends at a rate of 8.5% per annum.

We own 50,000 shares of 6% Non-Cumulative Perpetual Preferred Stock of BAC (“BAC Preferred”) with a liquidation value of $100,000 per share and warrants to purchase 700,000,000 shares of common stock of BAC (“BAC Warrants”). The BAC Preferred is redeemable at the option of BAC beginning on May 7, 2019 at a redemption price of $105,000 per share (or $5.25 billion in aggregate). The BAC Warrants expire in 2021 and are exercisable for an additional aggregate cost of $5 billion ($7.142857/share).

We own Class A 9% Cumulative Compounding Perpetual Preferred Shares of RBI (“RBI Preferred”) having a stated value of $3 billion. RBI, domiciled in Canada, is the ultimate parent company of Burger King and Tim Hortons. The RBI Preferred is entitled to dividends on a cumulative basis of 9% per annum plus an additional amount, if necessary, to produce an after-tax yield to Berkshire as if the dividends were paid by a U.S.-based company. The RBI Preferred is redeemable at the option of RBI beginning on December 12, 2017. If not redeemed prior to December 12, 2024, we can cause RBI to redeem the RBI Preferred. In either case, the redemption price will be 109.9% of the stated value of such shares.

Note 7. Investments in The Kraft Heinz Company

On June 7, 2013, Berkshire and an affiliate of the global investment firm 3G Capital (such affiliate, “3G”), each made equity investments in H.J. Heinz Holding Corporation (“Heinz Holding”), which, together with debt financing obtained by Heinz Holding, was used to acquire H. J. Heinz Company (“Heinz”). Berkshire’s initial investments consisted of 425 million shares of Heinz Holding common stock, warrants, which were exercised in June 2015, to acquire approximately 46 million additional shares of common stock at one cent per share, and cumulative compounding preferred stock (“Preferred Stock”) with a liquidation preference of $8 billion. The aggregate cost of our investments was $12.25 billion. 3G also acquired 425 million shares of Heinz Holding common stock for $4.25 billion. On June 7, 2016, our Preferred Stock investment was redeemed for cash of $8.32 billion. Prior to its redemption, the Preferred Stock was entitled to dividends at 9% per annum.

On July 1, 2015, Berkshire acquired 262.9 million shares of newly issued common stock of Heinz Holding for $5.26 billion and 3G acquired 237.1 million shares of newly issued common stock for $4.74 billion. Immediately thereafter, Heinz Holding executed a reverse stock split at a rate of 0.443332 of a share for each share.

On July 2, 2015, Heinz Holding acquired Kraft Foods Group, Inc. (“Kraft”). Upon completion of the acquisition, Heinz Holding was renamed The Kraft Heinz Company (“Kraft Heinz”). Kraft Heinz is one of the 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, in the world. Kraft Heinz’s leading iconic brands include Kraft, Heinz, ABC, Capri Sun, Classico, Jell-O, Kool-Aid, Lunchables, Maxwell House, Ore-Ida, Oscar Mayer, Philadelphia, Planters, Plasmon, Quero, Weight Watchers Smart Ones and Velveeta.

In connection with Heinz Holding’s acquisition of Kraft, Kraft shareholders received one share of newly issued Heinz Holding common stock for each share of Kraft common stock and a special cash dividend of $16.50 per share. Following the issuance of these additional shares, Berkshire and 3G together owned approximately 51% of the outstanding Kraft Heinz common stock, with Berkshire owning approximately 26.8% and 3G owning 24.2%. We account for our investment in Kraft Heinz common stock on the equity method. Under the equity method, the issuance of shares by an investee is accounted for by the investor as if the investor had sold a proportionate share of its investment. As a result, we recorded a non-cash pre-tax holding gain of approximately $6.8 billion in the third quarter of 2015, representing the excess of the fair value of Kraft Heinz common stock at the date of the merger over our carrying value associated with the reduction in our ownership.

A summary of our investments in Kraft Heinz follows (in millions).

	Carrying Value
	September 30,  2016		December 31,  2015
Common stock		$15,711		$15,714
Preferred Stock		—		7,710
		$15,711		$23,424

Our equity method earnings on the common stock and dividends earned on the Preferred Stock in the first nine months of 2016 and 2015 were $851 million and $329 million, respectively, and are included in interest, dividend and other investment income in our Consolidated Statements of Earnings. Preferred Stock dividends received in the first nine months of 2016 were $180 million. In 2015, Preferred Stock dividends received were $180 million in the third quarter and $540 million in the first nine months.

Notes to Consolidated Financial Statements (Continued)

Note 8. Income taxes

Our consolidated effective income tax rates for the third quarter and first nine months of 2016 were 30.3% and 25.8%, respectively. In 2015, our effective income tax rates were 32.3% for the third quarter and 31.6% for the first nine months. Our effective income tax rate normally reflects benefits from the recurring impact of (a) dividends received deductions applicable to certain investments in equity securities, (b) income production tax credits from wind-powered electricity generation placed in service in the U.S. and (c) lower income tax rates applicable to earnings of certain foreign subsidiaries.

As discussed in Notes 3 and 9 to these Consolidated Financial Statements, on February 29, 2016, we exchanged our long-held investment in P&G common stock for the common stock of Duracell. This exchange produced a pre-tax gain of $1.1 billion for financial reporting purposes. The exchange transaction was structured as a tax-free reorganization under the Internal Revenue Code. As a result, no income taxes are currently payable on the excess of the fair value of the business received over the tax basis of the P&G shares exchanged and we recorded a one-time reduction of certain deferred income tax liabilities (approximately $750 million) that were recorded in 2005 in connection with our exchange of The Gillette Company common stock for P&G common stock upon the merger of those two companies. The P&G/Duracell exchange produced a 4.7 percentage point reduction in our consolidated effective income tax rate for the first nine months of 2016.

Note 9. Investment gains/losses

Investment gains/losses are summarized below (in millions).

	Third Quarter				First Nine Months
	2016		2015		2016		2015
Fixed maturity securities—
Gross gains from sales and redemptions	$	5	$	6	$	44	$	88
Gross losses from sales and redemptions		(24)		(44)		(41)		(128)
Equity securities—

Gross losses from sales and redemptions		(13)		(75)		(76)		(95)
Other-than-temporary impairment losses		—		(26)		(63)		(26)
Other		9		(2)		59		31
	$	3,150	$	8,266	$	5,643	$	8,725

Gains from sales and redemptions of equity securities in 2016 included gains of approximately $2.4 billion from the disposition of our investment in Wrigley preferred stock in the third quarter, and in the first nine months also included $610 million from the redemption of our investment in Kraft Heinz Preferred Stock and a non-cash holding gain of approximately $1.1 billion from the exchange of our P&G common stock in connection with the acquisition of Duracell. The non-cash gain from the P&G/Duracell exchange represented the excess of the fair value of net assets of Duracell over the cost basis of the P&G stock exchanged. Gains from sales and redemptions of equity securities in the third quarter and first nine months of 2015 included a non-cash holding gain of approximately $6.8 billion in connection with our investment in Kraft Heinz common stock.

We record investments in equity and fixed maturity securities classified as available-for-sale at fair value and record the difference between fair value and cost in other comprehensive income. Other-than-temporary impairment losses recognized in earnings represent reductions in the cost basis of the investment, but not the fair value. Accordingly, such losses that are included in earnings are generally offset by a credit to other comprehensive income, producing no net effect on shareholders’ equity as of the balance sheet date.

Note 10. Inventories

Loans and finance receivables are predominantly originated or acquired manufactured housing installment loans. Provisions for loan losses in the first nine months of 2016 and 2015 were $124 million and $119 million, respectively. Loan charge-offs, net of recoveries, in the first nine months of 2016 and 2015 were $123 million and $136 million, respectively. At September 30, 2016, approximately 98% of the loan balances were evaluated collectively for impairment. As a part of the evaluation process, credit quality indicators are reviewed and loans are designated as performing or non-performing. At September 30, 2016, approximately 98% of the loan balances were determined to be performing and approximately 94% of the loan balances were current as to payment status.

Note 14. Derivative contracts (Continued)

The derivative contracts of our finance and financial products businesses are recorded at fair value and the changes in the fair values of such contracts are reported in earnings as derivative gains/losses. We entered into these contracts with the expectation that the premiums received would exceed the amounts ultimately paid to counterparties. A summary of the derivative gains (losses) included in our Consolidated Statements of Earnings follows (in millions).

	Third Quarter				First Nine Months
	2016		2015		2016			2015
Equity index put options	$	458	$	(802)	$	(421	)	$	371
Credit default		—		38		89			9
	$	458	$	(764)	$	(332	)	$	380

The equity index put option contracts are European style options written between 2004 and 2008 on four major equity indexes. These contracts will expire between June 2018 and January 2026. Future payments, if any, under any given contract will be required if the prevailing index value is below the contract strike price at the expiration date. We received the premiums on these contracts at the inception dates and therefore we have no 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) of our equity index put option contracts was approximately $1.6 billion at September 30, 2016 and $1.1 billion at December 31, 2015. However, these contracts may not be unilaterally terminated or fully settled before the expiration dates. Therefore, the ultimate amount of cash basis gains or losses on these contracts will not be determined for several years. The remaining weighted average life of all contracts was approximately 4.2 years at September 30, 2016.

A limited number of our equity index put option contracts contain collateral posting requirements with respect to changes in the fair value or intrinsic value of the contracts and/or a downgrade of Berkshire’s credit ratings. As of September 30, 2016, we did not have any collateral posting requirements. If Berkshire’s credit ratings (currently AA from Standard & Poor’s and Aa2 from Moody’s) are downgraded below either A- by Standard & Poor’s or A3 by Moody’s, collateral of up to $1.1 billion could be required to be posted.

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. Derivative instruments, including forward purchases and sales, futures, swaps and options, are used to manage a portion of these price risks. Derivative contract assets are included in other assets and were $105 million as of September 30, 2016 and $103 million as of December 31, 2015. Derivative contract liabilities are included in accounts payable, accruals and other liabilities and were $198 million as of September 30, 2016 and $237 million as of December 31, 2015. Net derivative contract assets or liabilities that are probable of recovery through rates of our regulated utilities are offset by regulatory liabilities or assets. Unrealized gains or losses on contracts accounted for as cash flow or fair value hedges are recorded in other comprehensive income or in net earnings, as appropriate.

Other subsidiary borrowings due 2016-2044		4.0%		7,387		2,811
			$	27,514	$	14,599

On January 8, 2016, Berkshire entered into a $10 billion 364-day revolving credit agreement. In connection with the PCC acquisition, Berkshire borrowed $10 billion under the credit agreement. In March 2016, Berkshire issued €2.75 billion in senior unsecured notes consisting of €1.0 billion of 0.50% notes due in 2020, €1.0 billion of 1.30% notes due in 2024 and €750 million of 2.15% notes due in 2028. Berkshire also issued $5.5 billion in senior unsecured notes consisting of $1.0 billion of 2.20% notes due in 2021, $2.0 billion of 2.75% notes due in 2023 and $2.5 billion of 3.125% notes due in 2026. The proceeds from these debt issues were used in the repayment of all outstanding borrowings under the aforementioned credit agreement. In June 2016, the revolving credit agreement was terminated. In August 2016, Berkshire issued $750 million in senior unsecured notes consisting of $500 million of 1.15% notes due in 2018 and $250 million of floating rate notes due in 2018, to replace $750 million of maturing debt. Other subsidiary borrowings at September 30, 2016 included $4.7 billion attributable to PCC.

	Weighted Average   Interest Rate		September 30,  2016		December 31,  2015
Railroad, utilities and energy:
Berkshire Hathaway Energy Company (“BHE”) and its subsidiaries:
BHE senior unsecured debt due 2017-2045		5.1%	$	7,817	$	7,814

Burlington Northern Santa Fe (“BNSF”) due 2016-2097		4.8%		22,166		21,737
			$	58,811	$	57,739

BHE subsidiary debt represents amounts issued pursuant to separate financing agreements. Substantially all of the assets of certain BHE subsidiaries are, or may be, pledged or encumbered to support or otherwise secure debt. These borrowing arrangements generally contain various covenants including, but not limited to, leverage ratios, interest coverage ratios and debt service coverage ratios. BNSF’s borrowings are primarily senior unsecured debentures. In May 2016, BNSF issued $750 million of 3.9% debentures due in 2046. As of September 30, 2016, BNSF and 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.

	Weighted Average  Interest Rate	September 30,  2016		December 31,  2015
Finance and financial products:
Berkshire Hathaway Finance Corporation (“BHFC”) due 2017-2043	2.5%	$	14,421	$	10,679
Other subsidiary borrowings due 2016-2036	5.0%		1,052		1,272
		$	15,473	$	11,951

In March 2016, BHFC issued $3.5 billion of senior notes consisting of $750 million of 1.45% notes due in 2018, $1.0 billion of floating rate notes due in 2018, $1.25 billion of 1.70% notes due in 2019 and $500 million of floating rate notes due in 2019. In August 2016, BHFC issued $1.25 billion of senior notes consisting of $1 billion of 1.30% notes due in 2019 and $250 million of floating rate notes due in 2019, primarily to replace $1 billion of maturing debt. The borrowings of BHFC, a wholly owned finance subsidiary of Berkshire, are fully and unconditionally guaranteed by Berkshire.

As of September 30, 2016, our subsidiaries also had unused lines of credit and commercial paper capacity aggregating approximately $8.2 billion to support short-term borrowing programs and provide additional liquidity. Such unused lines of credit included about $4.0 billion related to BHE and its subsidiaries. In addition to BHFC’s borrowings, Berkshire guarantees certain other subsidiary borrowings, which aggregated approximately $3.2 billion at September 30, 2016. 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 present and future payment obligations.

Note 17. Fair value measurements (Continued)

The fair values of substantially all of our financial instruments were measured using market or income approaches. Considerable judgment may be required in interpreting market data used to develop the estimates of fair value. Accordingly, the fair values presented are not necessarily indicative of the amounts that could be realized in an actual current market exchange. The use of alternative market assumptions and/or estimation methodologies may have a material effect on the estimated fair value. The hierarchy for measuring fair value consists of Levels 1 through 3, which are described below.

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

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

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

Reconciliations of assets and liabilities measured and carried at fair value on a recurring basis with the use of significant unobservable inputs (Level 3) for the nine months ending September 30, 2016 and 2015 follow (in millions).

Gains and losses included in earnings are included as components of investment gains/losses, derivative gains/losses or other revenues, as appropriate and are primarily related to changes in the fair values of derivative contracts and settlement transactions. Gains and losses included in other comprehensive income primarily represent the net change in unrealized appreciation of investments. In the third quarter of 2016, our investment in Wrigley preferred stock was redeemed.

Note 17. Fair value measurements (Continued)

Quantitative information as of September 30, 2016, with respect to assets and liabilities measured and carried at fair value on a recurring basis with the use of significant unobservable inputs (Level 3) follows (in millions).

	Fair   Value		Principal Valuation Techniques	Unobservable Inputs		Weighted Average
Other investments:
Preferred stocks	$	11,615	Discounted cash flow		Expected duration		6 years
					Discount for transferability restrictions and subordination		159 basis points
Common stock warrants		5,502	Warrant pricing model		Discount for transferability and hedging restrictions		7%
Net derivative liabilities:
Equity index put options		3,973	Option pricing model		Volatility		21%

Other investments consist of perpetual preferred stocks and common stock warrants that we acquired in private placement transactions. These investments are subject to contractual restrictions on transferability and may contain provisions that prevent us from economically hedging our investments. In applying discounted estimated cash flow techniques in valuing the perpetual preferred stocks, we made assumptions regarding the expected durations of the investments, as the issuers may have the right to redeem or convert these investments. We also made estimates regarding the impact of subordination, as the preferred stocks have a lower priority in liquidation than debt instruments of the issuers. In valuing the common stock warrants, we used a warrant valuation model. While most of the inputs to the model are observable, we are subject to the aforementioned contractual restrictions and we have applied discounts with respect to such restrictions. Increases or decreases to these inputs would result in decreases or increases to the fair values of the investments.

Our equity index put option 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 and many contracts have relatively long durations. For these and other reasons, we classified these contracts as Level 3. The methods we use to value these contracts are those that we believe market participants would use in determining exchange prices with respect to our contracts.

We value equity index put option contracts based on the Black-Scholes option valuation model. Inputs to this model include the index price, contract duration and dividend and interest rates (including a Berkshire non-performance input) which are observable. However, we believe that the valuation of long-duration options using any model is inherently subjective and, given the lack of observable transactions and prices, acceptable values may be subject to wide ranges. Volatility inputs represent our expectations, which consider the remaining duration of each contract and assume that the contracts will remain outstanding until the expiration dates without offsetting transactions occurring in the interim. Increases or decreases in the volatility inputs will produce increases or decreases in the fair values of the liabilities.

Note 18. Common stock (Continued)

Each Class A common share is entitled to one vote per share. Class B common stock possesses dividend and distribution rights equal to one-fifteen-hundredth (1/1,500) of such rights of Class A common stock. Each Class B common share possesses voting rights 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 1,644,031 shares outstanding as of September 30, 2016 and 1,643,393 shares outstanding as of December 31, 2015. In addition to our common stock, 1,000,000 shares of preferred stock are authorized, but none are issued.

Berkshire’s Board of Directors (“Berkshire’s Board”) has approved a common stock repurchase program under which Berkshire may repurchase its Class A and Class B shares at prices no higher than a 20% premium over the book value of the shares. Berkshire may repurchase shares in the open market or through privately negotiated transactions. Berkshire’s Board authorization does not specify a maximum number of shares to be repurchased. However, repurchases will not be made if they would reduce Berkshire’s consolidated cash and cash equivalent holdings below $20 billion. The repurchase program does not obligate Berkshire to repurchase any dollar amount or number of Class A or Class B shares and there is no expiration date to the program.

Note 20. Contingencies and Commitments

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

We own a 50% interest in a joint venture, Berkadia Commercial Mortgage LLC (“Berkadia”), with Leucadia National Corporation (“Leucadia”) owning the other 50% interest. Berkadia is a servicer of commercial real estate loans in the U.S., performing primary, master and special servicing functions for U.S. government agency programs, commercial mortgage-backed securities transactions, banks, insurance companies and other financial institutions. A significant source of funding for Berkadia’s operations is through the issuance of commercial paper. Repayment of the commercial paper is supported by a surety policy issued by a Berkshire insurance subsidiary. Leucadia has agreed to indemnify us for one-half of any losses incurred under the policy. Berkadia’s maximum outstanding balance of commercial paper borrowings is currently limited to $1.5 billion. On September 30, 2016, the aggregate amount of Berkadia commercial paper outstanding was $1.47 billion.

In the third quarter of 2016, our wholly-owned subsidiary, National Indemnity Company entered into a definitive agreement to acquire Medical Liability Mutual Insurance Company (“MLMIC”), a writer of medical professional liability insurance domiciled in New York. MLMIC’s assets and policyholders’ surplus determined under statutory accounting principles as of June 30, 2016 were approximately $5.5 billion and $1.9 billion, respectively. The acquisition price will be an amount equal to the sum of: (i) the tangible book value of MLMIC at the closing date (determined under U.S. GAAP); plus (ii) $100 million. The acquisition will involve the conversion of MLMIC from a mutual company to a stock company. The closing of the transaction is subject to various regulatory approvals, customary closing conditions and the approval of the MLMIC policyholders eligible to vote on the proposed demutualization and sale. The transaction is currently expected to be completed in late 2017.

Through our subsidiaries, we engage in a number of diverse business activities. Our operating businesses are managed on an unusually decentralized basis. There are essentially no centralized or integrated business functions (such as sales, marketing, purchasing, legal or human resources) and there is minimal involvement by our corporate headquarters in the day-to-day business activities of the operating businesses. 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. It also is responsible for establishing and monitoring Berkshire’s corporate governance practices, including, but not limited to, communicating the appropriate “tone at the top” messages to its employees and associates, monitoring governance efforts, including those at the operating businesses, and participating in the resolution of governance-related issues as needed. The business segment data (Note 21 to the accompanying Consolidated Financial Statements) should be read in conjunction with this discussion.

Earnings of our insurance underwriting operations were lower in the third quarter and first nine months of 2016 as compared to 2015. In the first nine months of 2016, the Berkshire Hathaway Reinsurance and Primary Groups generated lower net underwriting earnings while GEICO and General Re had earnings increases. Our railroad business generated lower net earnings in the third quarter and first nine months of 2016, primarily due to a 6.6% year-to-date decline in unit volume. Earnings of our utilities and energy businesses increased in the third quarter and first nine months of 2016 which was attributable to increased pre-tax earnings and lower effective income tax rates. The increases in net earnings from our manufacturing, service and retailing businesses reflected the impact of the PCC and Duracell acquisitions, partly offset by lower aggregate earnings from the other businesses within this group.

After-tax investment and derivative gains in the third quarter and first nine months were approximately $2.3 billion and $4.6 billion, respectively, in 2016 compared to $4.9 billion and $5.9 billion, respectively, in 2015. After-tax investment gains in the third quarter of 2016 included approximately $1.6 billion from the sale of our Wrigley preferred stock investment and in the first nine months also included non-cash gains of approximately $1.9 billion related to the exchange of P&G common stock for 100% of the common stock of Duracell. After-tax investment and derivative gains in the third quarter of 2015 included non-cash holding gains of approximately $4.4 billion in connection with our investment in Kraft Heinz common stock. We believe that investment and derivative gains/losses are often meaningless in terms of understanding our reported results or evaluating our economic performance. Investment and derivative gains and losses have caused and will likely continue to cause significant volatility in our periodic earnings.

Insurance—Underwriting

We engage in both primary insurance and reinsurance of property/casualty, life and health risks. In primary insurance activities, we assume defined portions of the risks of loss from persons or organizations that are directly subject to the risks. In reinsurance activities, we assume defined portions of similar or dissimilar risks that other insurers or reinsurers have subjected themselves to in their own insuring activities. Our insurance and reinsurance businesses are: (1) GEICO, (2) General Re, (3) Berkshire Hathaway Reinsurance Group (“BHRG”) and (4) Berkshire Hathaway Primary Group.

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

Insurance—Underwriting (Continued)

Our management views insurance businesses as possessing two distinct operations – underwriting and investing. Underwriting decisions are the responsibility of the unit managers; investing decisions, with limited exceptions, are the responsibility of Berkshire’s Chairman and CEO, Warren E. Buffett. Accordingly, we evaluate performance of underwriting operations without any allocation of investment income or investment gains.

The timing and amount of large property catastrophe losses can produce significant volatility in our periodic underwriting results, particularly with respect to our reinsurance businesses. In the first nine months of 2016, we had no significant catastrophe losses. Based on preliminary estimates, we believe that losses arising from Hurricane Matthew in October 2016 will not be material. In the third quarter of 2015, we recorded estimated losses of $130 million in connection with a property loss event in China. Our periodic underwriting results may be affected significantly by changes in estimates for unpaid losses and loss adjustment expenses, including amounts established for occurrences in prior years. Actual claim settlements and revised loss estimates will develop over time. Unpaid loss estimates recorded as of the balance sheet date will develop upward or downward in future periods, producing a corresponding decrease or increase to pre-tax earnings. Variations in foreign currency exchange rates can produce relatively significant foreign currency exchange gains and losses in our periodic earnings with respect to non-U.S. dollar liabilities of our U.S.-based insurance subsidiaries.

A key marketing strategy of our insurance businesses is the maintenance of extraordinary capital strength. A measure of capital strength is combined shareholders’ equity determined pursuant to U.S. statutory accounting rules (“Statutory Surplus”). Statutory Surplus of our insurance businesses was approximately $124 billion at December 31, 2015. This superior capital strength creates opportunities, especially with respect to reinsurance activities, to negotiate and enter into insurance and reinsurance contracts specially designed to meet the unique needs of insurance and reinsurance buyers. Underwriting results of our insurance businesses are summarized below. Amounts are in millions.

GEICO

GEICO writes private passenger automobile insurance, offering coverages to insureds in all 50 states and the District of Columbia. GEICO’s policies are marketed mainly by direct response methods in which customers apply for coverage directly to the company via the Internet or over the telephone. This is a significant element in our strategy to be a low-cost auto insurer. In addition, we strive to provide excellent service to customers, with the goal of establishing long-term customer relationships. GEICO’s underwriting results are summarized below. Dollars are in millions.

GEICO (Continued)

Premiums written in the third quarter and first nine months of 2016 were $7.0 billion and $19.8 billion, respectively, increases of 13.6% and 12.2%, respectively, compared to the third quarter and first nine months of 2015. Premiums earned in 2016 increased $686 million (11.9%) in the third quarter and $2.0 billion (11.8%) in the first nine months, as compared to the same periods in 2015. These increases reflected voluntary auto policy-in-force growth of 5.2% and increased average premiums per auto policy of approximately 6.9% over the past twelve months, which were attributable to rate increases, coverage changes and changes in state and risk mix. Throughout 2015, we experienced increases in claims frequencies and severities across all of our major coverages. As a result, we implemented premium rate increases as necessary. Voluntary auto new business sales in 2016 increased 16.5% in the third quarter and 6.8% in the first nine months compared to 2015. The significant growth in voluntary auto new business during the third quarter has continued in October. In 2016, voluntary auto policies-in-force increased by approximately 276,000 in the third quarter and 670,000 in the first nine months.

Losses and loss adjustment expenses incurred in 2016 increased $677 million (14.5%) in the third quarter and $1.7 billion (12.1%) in the first nine months, as compared to 2015. In 2016, our loss ratio (the ratio of losses and loss adjustment expenses to earned premiums) increased 2.0 percentage points in the third quarter and 0.3 percentage points in the first nine months as compared to 2015, reflecting increased storm losses and claims severity, partly offset by the aforementioned premium rate increases. Claims frequencies (claim counts per exposure unit) in the first nine months of 2016 for property damage and collision coverages were relatively unchanged as the decreases experienced in the first quarter were offset by subsequent increases. Claim frequencies for bodily injury coverage for the first nine months of 2016 were relatively unchanged from 2015. Average claims severities were higher in the first nine months of 2016 for physical damage and collision coverages (four to six percent range) and bodily injury coverage (five to seven percent range). In addition, storm-related losses (primarily from hail and flooding) in the third quarter and first nine months of 2016 were approximately $90 million and $380 million, respectively, compared to $5 million and $129 million, respectively, in the corresponding 2015 periods.

Underwriting expenses in the third quarter and first nine months of 2016 were $1.0 billion and $2.9 billion, respectively, increases of $129 million (14.8%) and $240 million (9.1%), respectively, over 2015. Our expense ratio (underwriting expenses to premiums earned) in 2016 increased 0.4 percentage points in the third quarter and decreased 0.4 percentage points in the first nine months compared to 2015. The largest components of underwriting expenses are employee-related expenses (salaries and benefits) and advertising costs. The increases in underwriting expenses reflected the increases in policies-in-force.

General Re

General Re conducts a reinsurance business offering property and casualty coverages to clients worldwide through General Reinsurance Corporation, Germany-based General Reinsurance AG, Faraday Holdings in London and other wholly-owned affiliates. Property and casualty reinsurance is written primarily on a direct basis, but is also written through brokers and intermediaries. Life and health reinsurance is written primarily on a direct basis through General Re Life Corporation and General Reinsurance AG. General Re strives to generate underwriting profits in essentially all of its product lines. Our management does not evaluate underwriting performance based upon market share and our underwriters are instructed to reject inadequately priced risks. General Re’s underwriting results are summarized in the following table. Amounts are in millions.

	Premiums earned								Pre-tax underwriting gain (loss)
	Third Quarter				First Nine Months				Third Quarter				First Nine Months
	2016		2015		2016		2015		2016		2015		2016		2015

	$	1,389	$	1,405	$	4,168	$	4,397	$	100	$	(2)	$	144	$	58

Property/casualty

In the third quarter of 2016, property/casualty premiums written were relatively unchanged from 2015, reflecting a modest increase in North America, offset by modestly lower volume in international markets. In the first nine months, property/casualty premiums written in 2016 declined $215 million (9%) compared to 2015, primarily due to lower volume in international treaty and broker market business, and to a lesser degree, to unfavorable foreign currency exchange rate changes. In 2016, premiums earned decreased $40 million (6%) in the third quarter and $200 million (9%) in the first nine months as compared to the same periods in 2015. The declines in earned premiums reflected lower volume and unfavorable changes in foreign currency exchange rates. Insurance industry capacity remains high and price competition in most property/casualty reinsurance markets persists. We continue to decline business when we believe prices are inadequate. However, we remain prepared to write substantially more business when more appropriate prices can be attained.

Insurance—Underwriting (Continued)

General Re (Continued)

Our property business generated pre-tax underwriting gains of $76 million in the third quarter and $154 million in the first nine months of 2016 compared to gains of $15 million and $114 million, respectively, in the corresponding 2015 periods. There were no significant catastrophe losses during the first nine months of 2016, while underwriting results in 2015 included estimated losses of $44 million from an explosion in Tianjin, China during the third quarter. In the first nine months of 2016, we recognized pre-tax gains from reductions of estimated losses on prior years’ business of approximately $160 million, which were relatively unchanged from 2015.

Our casualty/workers’ compensation business produced pre-tax underwriting losses of $10 million in the third quarter and $35 million in the first nine months of 2016 and pre-tax losses of $24 million in the third quarter and $49 million in the first nine months of 2015. Underwriting results in 2016 and 2015 included net losses on current year business and charges for recurring discount accretion on workers’ compensation liabilities and deferred charge amortization on retroactive reinsurance contracts, partially offset by gains from reductions of estimated losses on prior years’ business. Casualty losses tend to be long-tailed and it should not be assumed that favorable loss experience in a given period means that the ultimate liability estimates currently established will continue to develop favorably.

Life/health

In the third quarter and first nine months of 2016, life/health premiums earned increased $24 million (3%) and decreased $29 million (1%), respectively, compared to 2015. Adjusting for changes in foreign currency exchange rates, premiums earned in 2016 increased $31 million (4%) in the third quarter and $32 million (1%) in the first nine months, reflecting growth across a number of non-U.S. markets, particularly in Asia and the United Kingdom. Our life/health business produced pre-tax underwriting gains of $25 million in the first nine months of 2016 compared to losses of $7 million in the first nine months of 2015. In the first nine months of 2016, underwriting results reflected gains from our international life business offset by losses from the recurring discount accretion on long-term care liabilities and higher than expected individual life claim frequency in North America. Our international underwriting results in 2016 were adversely affected by increased liabilities for estimated premium deficiencies on certain disability business in the second quarter, partly offset by reductions in both foreign currency exchange losses and the adverse impact from lower interest rates compared to 2015.

Berkshire Hathaway Reinsurance Group

BHRG underwrites excess-of-loss reinsurance and quota-share coverages on property and casualty risks for insurers and reinsurers worldwide, including property catastrophe insurance and reinsurance. BHRG also writes retroactive reinsurance on property/casualty exposures as well as life reinsurance and periodic payment annuity business. BHRG’s underwriting results are summarized in the table below (in millions).

	Premiums earned								Pre-tax underwriting gain (loss)
	Third Quarter				First Nine Months				Third Quarter				First Nine Months

	$	1,872	$	1,892	$	5,767	$	5,317	$	(19)	$	199	$	86		$	247

Property/casualty

Premiums written in the third quarter and first nine months of 2016 decreased $945 million (50.2%) and $322 million (8.2%), respectively, compared to 2015. The decline during the third quarter was primarily due to the impact of the quota-share contract with Insurance Australia Group Ltd. (“IAG”), which became effective on July 1, 2015. Premiums written in the third quarter of 2015 included a quota-share percentage of IAG’s unearned premiums in-force as of the effective date. Premiums earned decreased $177 million (13.2%) in the third quarter and increased $190 million (6.0%) in the first nine months compared to 2015. The increase in the first nine months was primarily attributable to increased premiums earned from the IAG contract, partially offset by lower premiums from property business. Our premium volume is generally constrained for most property/casualty reinsurance coverages, and for property catastrophe reinsurance in particular as rates, in our view, are generally inadequate. However, we have the capacity and desire to write more business when appropriate pricing can be obtained.

Our property/casualty business generated pre-tax underwriting gains of $40 million and $415 million in the third quarter and first nine months of 2016, respectively, compared to $315 million and $737 million, respectively, in 2015. In the third quarter of 2015, the property/casualty business incurred losses of $86 million from an explosion in Tianjin, China. The declines in pre-tax underwriting gains in 2016 were primarily due to comparatively lower gains from reductions of estimated losses on prior years’ events.

Retroactive reinsurance

Retroactive reinsurance contracts provide indemnification of losses and loss adjustment expenses with respect to past loss events, and related claims are generally expected to be paid over long periods of time. At the inception of a contract, deferred charge assets are recorded for the excess, if any, of the estimated ultimate losses payable over the premiums earned. Deferred charges are subsequently amortized over the estimated claims payment period based on estimates of the timing and amount of future loss payments. The original estimates of the timing and amount of loss payments are periodically analyzed against actual experience and revised based on an actuarial evaluation of the expected remaining losses. Amortization charges and deferred charge adjustments resulting from changes to the estimated timing and amount of future loss payments are included in periodic earnings.

Pre-tax underwriting results from retroactive reinsurance contracts also include foreign currency transaction gains/losses associated with foreign currency denominated liabilities of U.S.-based subsidiaries. In 2016, foreign currency gains were $21 million in the third quarter and $198 million in the first nine months. In 2015, foreign currency gains were $120 million in the third quarter and $92 million in the first nine months. Before foreign currency gains/losses, retroactive reinsurance contracts produced pre-tax losses in the first nine months of $394 million in 2016 and $375 million in 2015, primarily from recurring periodic deferred charge amortization. Gross unpaid losses assumed under retroactive reinsurance contracts were approximately $23.7 billion at September 30, 2016 and at December 31, 2015. Unamortized deferred charges related to such reinsurance contracts were approximately $7.4 billion at September 30, 2016 and $7.6 billion at December 31, 2015.

Life and annuity

BHRG’s life and annuity underwriting results are summarized as follows. Amounts are in millions.

	Premiums earned								Pre-tax underwriting gain (loss)
	Third Quarter				First Nine Months				Third Quarter				First Nine Months
	2016		2015		2016		2015		2016		2015		2016		2015
Periodic payment annuity	$	367	$	195	$	771	$	1,062	$	(61)	$	(6)	$	(123)	$	(159)

	$	708	$	550	$	1,827	$	2,145	$	55	$	(118)	$	(133)	$	(207)

Premiums earned in 2016 from periodic payment annuity contracts increased $172 million (88.2%) in the third quarter and declined $291 million (27.4%) in the first nine months compared to 2015. Premiums earned in 2016 increased in the third quarter due to increased direct annuity volume, which for the first nine months was more than offset by the impact of a sizable reinsurance contract written in the second quarter of 2015.

Periodic payment annuity contracts generated pre-tax underwriting losses of $61 million in the third quarter and $123 million in the first nine months of 2016 and $6 million in the third quarter and $159 million in the first nine months of 2015. Our periodic payment annuity liabilities under certain contracts of a U.S. subsidiary are denominated in foreign currencies, most significantly the Great Britain Pound (“GBP”). In 2016, the value of the U.S. Dollar strengthened versus the GBP, producing reductions in our liabilities in U.S. Dollars and resulting in pre-tax gains of $216 million in the first nine months of 2016 and $53 million in the first nine months of 2015. Before the impact of foreign currency exchange rate changes, pre-tax underwriting losses from annuity contracts were $111 million and $339 million in the third quarter and first nine months of 2016, respectively, compared to $66 million and $212 million, respectively, in the corresponding 2015 periods. This business is expected to generate underwriting losses attributable to the recurring accretion of discounted annuity liabilities. The increases in underwriting losses (before foreign currency impacts) reflected increased liabilities from new business written over the past two years and the impact of lower interest rates, which increased expected future loss payments under certain reinsurance contracts. Aggregate annuity liabilities were approximately $9.6 billion at September 30, 2016 and $8.7 billion at December 31, 2015.

In the third quarter and first nine months of 2016, life reinsurance premiums were relatively unchanged compared to 2015. The life reinsurance business produced a pre-tax underwriting loss of $9 million in the third quarter and a pre-tax gain of $5 million in the first nine months of 2016. Underwriting losses of $81 million in the first nine months of 2015 included losses of $53 million incurred in connection with business terminated in the second quarter.

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

Insurance—Underwriting (Continued)

Berkshire Hathaway Reinsurance Group (Continued)

Our variable annuity business primarily consists of contracts that provide guarantees on closed blocks of variable annuity business written by other insurers. The periodic underwriting gains and losses in each period reflect changes in liabilities for guaranteed benefits which are impacted by changes in securities markets and interest rates. Periodic results from these contracts can be volatile reflecting changes in investment market conditions, which impact the underlying insured exposures. In the third quarter of 2016, the pre-tax underwriting gains were primarily due to better than expected equity market performance, which was more than offset in the first nine months of 2016 by lower interest rates. In the third quarter of 2015, pre-tax underwriting losses were primarily due to lower equity markets and interest rates which partly offset the underwriting gains in the first six months.

Berkshire Hathaway Primary Group

The Berkshire Hathaway Primary Group (“BH Primary”) consists of several independently managed insurance businesses. These businesses include: MedPro Group, providers of healthcare malpractice insurance coverages; National Indemnity Company’s primary group (“NICO Primary”), writers of commercial motor vehicle and general liability coverages; U.S. Investment Corporation, whose subsidiaries underwrite specialty insurance coverages; a group of companies referred to as Berkshire Hathaway Homestate Companies (“BHHC”), providers of commercial multi-line and workers’ compensation insurance; Berkshire Hathaway Specialty Insurance (“BH Specialty”), which concentrates on providing large scale insurance solutions for commercial property and casualty risks; Applied Underwriters, a provider of integrated workers’ compensation solutions; Berkshire Hathaway GUARD Insurance Companies (“GUARD”), providers of workers’ compensation and commercial property and casualty insurance coverage to small and mid-sized businesses; and Central States Indemnity Company, a provider of credit and Medicare Supplement insurance.

Premiums earned in the first nine months of 2016 were $4.58 billion, an increase of 16.0% compared to 2015. The increase in premiums was primarily attributable to volume increases from BH Specialty, MedPro Group, BHHC and GUARD. The BH Primary insurers produced aggregate pre-tax underwriting gains of $485 million in the first nine months of 2016 and $566 million in 2015. Combined loss ratios were 61% in the first nine months of 2016 and 59% in 2015. The comparative increase in the loss ratio reflected comparative declines in favorable loss development of prior years’ loss events, partly offset by lower loss ratios on current year business. Our primary insurers write considerable amounts of liability and workers’ compensation business, which can have extended claim tails. It should not be assumed that the current claim experience or underwriting results will continue into the future.

Insurance—Investment Income

A summary of net investment income generated by investments held by our insurance operations follows. Amounts are in millions.

	Third Quarter				First Nine Months
	2016		2015		2016		2015
Interest income	$	224	$	221	$	668	$	675
Dividend income		805		824		2,738		2,791
Net investment income before income taxes and noncontrolling interests		1,029		1,045		3,406		3,466
Income taxes and noncontrolling interests		179		205		659		774
Net investment income	$	850	$	840	$	2,747	$	2,692

Pre-tax investment income in the third quarter and first nine months of 2016 declined $16 million (2%) and $60 million (2%), respectively, from 2015, due primarily to lower dividends from foreign issuers as a result of investment dispositions in 2015, partly offset by increased dividends from domestic issuers. We continue to hold significant cash and cash equivalents earning very low yields. We believe that maintaining ample liquidity is paramount and we insist on safety over yield with respect to such balances.

Invested assets of our insurance businesses derive from shareholder capital, including reinvested earnings, and from net liabilities under insurance contracts or “float.” The major components of float are unpaid losses, life, annuity and health benefit liabilities, unearned premiums and other liabilities to policyholders less premium and reinsurance receivables, deferred charges assumed under retroactive reinsurance contracts and deferred policy acquisition costs. Float approximated $91 billion at September 30, 2016 and $88 billion at December 31, 2015. The cost of float was negative as our insurance businesses overall generated pre-tax underwriting gains in each period.

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

Railroad (“Burlington Northern Santa Fe”) (Continued)

Consolidated revenues in the third quarter and first nine months of 2016 were approximately $5.2 billion and $14.5 billion, respectively, representing decreases of $433 million (7.7%) and $2.1 billion (12.4%), respectively, versus the corresponding periods in 2015. Pre-tax earnings in the third quarter and first nine months of 2016 declined 11.2% and 18.2%, respectively, compared to the same periods in 2015. In 2016, our revenues and earnings were negatively impacted by lower volumes versus 2015, particularly in the coal and petroleum products categories.

In the first nine months of 2016, revenues reflected comparative declines in average revenue per car/unit (6.5%) and in volumes (6.6%). The decrease in average revenue per car/unit was primarily attributable to lower fuel surcharge revenue driven by lower fuel prices and business mix changes. The fuel price impact on fuel surcharges generally lags its impact on fuel costs. This timing difference contributed to the decline in earnings in the first quarter of 2016 as compared to 2015 because the price of fuel declined more significantly in early 2015. The effect of the timing difference has moderated since the first quarter and is not expected to be significant in the fourth quarter.

Freight revenues from consumer products in the third quarter of 2016 were $1.7 billion, a decline of 3.4% from 2015, driven by a 3.6% decline in volume. Revenues for the first nine months of 2016 were $4.8 billion, a decline of 2.2% from 2015. Volume for the first nine months of 2016 was relatively flat, as increased automotive volumes, due to the addition of a new customer, and domestic intermodal volumes were offset by lower international intermodal volumes attributable to soft economic activity and excess retail inventories.

In the third quarter and first nine months of 2016, freight revenues from industrial products were $1.2 billion and $3.6 billion, respectively, which decreased 15.2% and 15.8%, respectively, from the comparable 2015 periods. The decreases reflected lower volumes (8.0% in the third quarter and 7.5% in the first nine months), primarily for petroleum products, reflecting pipeline displacement of U.S. crude rail traffic and lower U.S. oil production. This decline was partially offset by increased plastics products volume. For the first nine months of 2016, we also experienced lower demand for taconite and steel products partially offset by increased movements of non-owned rail equipment. With oil production at low levels, along with pipeline displacement of rail, we expect comparative volume declines in petroleum and related products for the remainder of 2016.

Freight revenues in 2016 from agricultural products increased 7.8% in the third quarter to $1.1 billion and decreased 1.8% to $3.1 billion in the first nine months compared to the same periods in 2015. The increase in revenue in the third quarter of 2016 was driven by a volume increase of 13.2% compared to 2015. The decrease in the first nine months of 2016 was primarily attributable to lower average revenue per car, partly offset by a volume increase of 6.7%. In the third quarter and first nine months of 2016 volumes increased primarily due to higher corn, soybeans and wheat exports.

Freight revenues in 2016 from coal declined 18.5% in the third quarter to $1.0 billion and 33.0% in the first nine months to $2.4 billion compared to the same periods in 2015. Coal volumes declined 13.0% in the third quarter and 26.5% in the first nine months of 2016. In recent years, demand for coal by utilities has declined as other fuel sources, particularly natural gas, have increased. Coal volumes in 2015 also benefitted from higher demand in the early part of the year as utility customers restocked coal inventories. Although natural gas prices have risen in the third quarter, we expect declines in coal volumes for the rest of 2016, driven by coal unit retirements and elevated utility coal inventories.

Operating expenses in the third quarter and first nine months of 2016 were $3.3 billion and $9.6 billion, respectively, representing decreases of $239 million (6.8%) and $1.2 billion (11.0%), respectively, compared to the same periods in 2015. Our ratios of operating expenses to revenues in 2016 increased 0.7 percentage points to 63.6% in the third quarter and 1.0 percentage points to 66.4% for the first nine months versus the corresponding 2015 periods.

Compensation and benefits expenses decreased $27 million (2.2%) for the third quarter and $291 million (7.6%) for the first nine months of 2016 as compared to 2015. The declines were primarily due to lower employment levels, as a result of lower freight volumes, and productivity improvements, partially offset by inflation. Fuel expenses declined $137 million (20.4%) in the third quarter and $721 million (34.7%) in the first nine months of 2016 as compared to 2015 due to lower average fuel prices and lower volumes. Purchased services declined $71 million (11.2%) in the third quarter and $120 million (6.3%) in the first nine months of 2016 as compared to 2015, due to volume-based and other cost reductions. Depreciation expense increased $31 million (6.2%) in the third quarter and $96 million (6.5%) in the first nine months of 2016 as compared to 2015, due to increased assets in service reflecting our ongoing capital additions and improvement programs. In the third quarter and first nine months of 2016, equipment rents, materials and other expense declined $35 million (7.0%) and $159 million (10.3%), respectively, compared to the same periods of 2015. These declines resulted from lower freight volumes and productivity improvements in both periods, as well as, lower derailment and other casualty related costs in the nine-month period.

Interest expense in the third quarter and first nine months of 2016 was $250 million and $744 million, respectively, increases of $12 million (5.0%) and $61 million (8.9%), respectively, compared to 2015. BNSF funds its capital expenditures with cash flow from operations and new debt issuances. The increased interest expense in 2016 resulted from higher average outstanding debt.

Utilities and Energy (“Berkshire Hathaway Energy Company”)

We hold an 89.9% ownership interest in Berkshire Hathaway Energy Company (“BHE”), which operates an international energy business. BHE’s domestic regulated utility interests are comprised of PacifiCorp, MidAmerican Energy Company (“MEC”), and NV Energy. In Great Britain, BHE subsidiaries operate two regulated electricity distribution businesses referred to as Northern Powergrid. BHE also owns two domestic regulated interstate natural gas pipeline companies. Other energy businesses include AltaLink, L.P. (“AltaLink”), a regulated electricity transmission-only business in Alberta, Canada and a diversified portfolio of independent power projects. In addition, BHE also operates the second-largest residential real estate brokerage firm and one of the largest real estate franchise networks in the United States.

The rates our regulated businesses charge customers for energy and services are based, in large part, on the costs of business operations, including a return on capital, and are subject to regulatory approval. To the extent these operations are not allowed to include such costs in the approved rates, operating results will be adversely affected. Revenues and earnings of BHE are summarized below. Amounts are in millions.

PacifiCorp

PacifiCorp operates a regulated electric utility in portions of several Western states, including Utah, Oregon and Wyoming. PacifiCorp’s revenues in the third quarter and first nine months of 2016 were $1.45 billion and $3.95 billion, respectively, and were relatively unchanged from 2015. Revenues in 2016 reflected increased retail revenues and lower wholesale revenues. The year-to-date increase in retail revenues was primarily due to higher retail rates as average customer loads were relatively unchanged. The declines in wholesale revenues were attributable to lower volumes and average prices. EBIT in the third quarter and first nine months of 2016 increased $11 million (3.1%) and $68 million (8.5%), respectively, from the same periods of 2015. The increases were primarily due to increased gross margins as energy costs declined due to lower fuel prices and changes in fuel mix.

MidAmerican Energy Company

MEC operates a regulated electric and natural gas utility primarily in Iowa and Illinois. Revenues increased $121 million (17.7%) in the third quarter of 2016 compared to 2015, while revenues in the first nine months were comparatively flat versus 2015. The revenue increase in the third quarter was primarily due to higher retail and wholesale electric revenues ($107 million). The increase in retail electric revenues resulted primarily from a 3.6% increase in customer load and higher electric rates, and the increase in wholesale revenues was due to increased wholesale prices and volumes and transmission revenue. Revenues in the first nine months of 2016 included increased electric revenues ($100 million), which were largely offset by lower natural gas revenues ($69 million) and other revenues. The decline in natural gas revenues was primarily due to lower average per-unit cost of gas sold ($61 million) which is offset in cost of sales, and a 6.3% decline in retail sales volumes, primarily from warmer winter temperatures in 2016. EBIT increased $78 million (47.9%) in the third quarter and $79 million (25.5%) in the first nine months of 2016 as compared to 2015. The increase in EBIT was primarily due to increased gross margins from electric revenues partially offset by higher depreciation and amortization from additional assets placed in service and higher interest expenses. In addition, EBIT in the first nine months of 2015 included a gain of $13 million from the sale of a generating facility lease.

NV Energy

NV Energy operates regulated electric and natural gas utilities in Nevada. Revenues in the third quarter and first nine months of 2016 were approximately $1.0 billion and $2.3 billion, respectively, decreases of $133 million (11.8%) and $353 million (13.1%), respectively, versus the same periods in 2015. The declines were primarily attributable to lower electric retail rates resulting from lower energy costs. Electric retail customer load in the first nine months of 2016 increased 1.4% compared to 2015. EBIT were relatively unchanged in the third quarter and fell $34 million (6.4%) in the first nine months of 2016 compared to 2015. In 2016, the negative impact of the revenue declines were substantially offset by the declines in energy costs. However, operating expenses increased $6 million (2%) in the third quarter and $48 million (7%) in the first nine months compared to 2015. The year-to-date increase resulted primarily from higher depreciation and amortization and property and other taxes. In addition, operating expenses in the first nine months of 2015 included non-recurring benefits from reductions in certain accrued liabilities.

Northern Powergrid

Revenues in the third quarter and first nine months of 2016 declined $44 million (16.7%) to $220 million and $103 million (12.1%) to $749 million, respectively, as compared to 2015. The unfavorable impact from a stronger U.S. Dollar reduced revenues by $40 million in the third quarter and $72 million in the first nine months. In the first nine months of 2016, revenues also declined, due to lower tariff rates from a new price control period that became effective April 1, 2015. EBIT in the third quarter and first nine months of 2016 declined $38 million (40.0%) to $57 million and $78 million (22.2%) to $274 million, respectively, as compared to 2015. The declines were primarily due to the impact of lower tariff rates and the stronger U.S. Dollar, as well as increases in depreciation and other operating expenses.

Natural gas pipelines

Revenues in the third quarter of 2016 increased 3.0% and for the first nine months declined 4.6% as compared to 2015. The revenue increase in the third quarter was primarily attributable to transportation revenues from expansion projects. For the first nine months of 2016, the decline was due to the impact of lower gas sales from balancing activities and lower transportation revenues from lower volumes and rates, in part due to comparatively milder temperatures in the first quarter. EBIT in 2016 increased $7 million (13.5%) in the third quarter and $11 million (4.0%) in the first nine months versus 2015. These increases reflected lower interest expense in 2016, as a result of lower average debt balances, partly offset by increased depreciation expense.

Other energy businesses

Revenues in the third quarter of 2016 increased $17 million (2.5%) and for the first nine months declined $105 million (5.9%) compared to the corresponding 2015 periods. The increase in third quarter revenues was primarily attributable to increased revenues from AltaLink as a result of increased assets in service. The declines in comparative revenues in the first nine months were principally attributable to lower revenues from AltaLink and from our unregulated retail services business. AltaLink’s year-to-date revenue decline reflected the impact of a regulatory decision in the second quarter that resulted in one-time net reductions in revenue, which more than offset increased revenues from additional assets placed in service. The regulatory decision changed the timing of when construction-in-progress expenditures included in rate base are billable to customers and earned in revenues, but had no impact on net earnings as the one-time revenue reduction was offset by one-time reductions in expenses.

EBIT in the third quarter of 2016 increased $13 million (6.8%) over 2015, while EBIT in the first nine months declined $5 million (1.5%) compared to 2015. The increase in third quarter EBIT was primarily due to increased earnings from our renewable energy and transmission businesses, while the decline in the first nine months reflected lower solar generation primarily from transformer related forced outages.

Real estate brokerage

Revenues in the third quarter and first nine months of 2016 increased 9.9% to $823 million and 10.4% to $2.16 billion, respectively, as compared to 2015. The increases were primarily attributable to increased closed brokerage transactions (primarily as a result of business acquisitions) and from modest increases in average home prices, as well as higher mortgage revenues. EBIT in the third quarter and first nine months of 2016 increased $9 million (11.3%) and $21 million (12.7%), respectively, compared to 2015, primarily reflecting the increases in mortgage revenues.

Corporate interest and income taxes

Corporate interest includes interest on unsecured debt issued by BHE and borrowings from certain Berkshire insurance subsidiaries. The declines in corporate interest in 2016 were primarily due to lower average borrowings from Berkshire insurance subsidiaries. BHE’s effective income tax rate for the first nine months was approximately 15.9% in 2016 and 19.8% in 2015. BHE’s effective income tax rates regularly reflect significant production tax credits from wind-powered electricity generation placed in service. In addition, pre-tax earnings of Northern Powergrid and AltaLink are taxed at lower statutory rates in the U.K. and Canada, respectively, compared to the statutory tax rate in the U.S.

Manufacturing, Service and Retailing (Continued)

Manufacturing (Continued)

Aggregate revenues in 2016 were approximately $12.1 billion in the third quarter and $34.8 billion in the first nine months, representing increases of approximately $2.9 billion (31.6%) and $7.3 billion (26.4%), respectively, from the corresponding 2015 periods. Pre-tax earnings were approximately $2.0 billion in the third quarter and $5.2 billion in the first nine months of 2016, representing increases of $722 million (57.3%) and $1.3 billion (33.5%), respectively, compared to the same periods in 2015. Excluding PCC and Duracell, aggregate pre-tax earnings increased 2.9% in the third quarter and were relatively unchanged in the first nine months.

Industrial products

Revenues in the third quarter and first nine months of 2016 increased approximately $2.2 billion (52.1%) and $5.7 billion (44.0%), respectively, versus the same periods in 2015. These increases were due to the inclusion of PCC, partially offset by revenue declines of $210 million (5.0%) in the third quarter and $832 million (6.4%) in the first nine months across our other businesses. In 2016, sales volumes of our other businesses were lower compared to 2015, reflecting sluggish demand for most products, and particularly for products sold to businesses in the oil and gas and heavy equipment industries. In addition, lower costs of oil-based raw materials and metals and increased competitive pressures continued to lower average selling prices.

Pre-tax earnings in 2016 increased $594 million (78.9%) in the third quarter and $1,147 million (48.1%) in the first nine months as compared to 2015. The increases in pre-tax earnings reflected the inclusion of PCC, partially offset by comparative declines in earnings (7.1% for the third quarter and 6.3% for the first nine months) from our other businesses, primarily IMC International, Lubrizol and several of Marmon’s businesses. Generally, these businesses were negatively affected by a combination of weaker customer demand and price and mix changes and increased restructuring costs, partly offset by the impacts of cost containment initiatives and lower average material prices. We expect the prevailing market conditions to continue during the remainder of 2016 and we may take additional cost containment actions in response to further slowdowns in customer demand.

Building products

Revenues in the third quarter and first nine months of 2016 increased $32 million (1.1%) and $303 million (3.9%), respectively, compared to the same periods in 2015. In the third quarter, volume-driven revenue increases achieved by MiTek and Johns Manville were partially offset by revenue declines at Benjamin Moore and Shaw. In the first nine months, the revenue increase reflected increased unit sales across most of our product categories, and was partly offset by lower average sales prices and changes in product mix.

Pre-tax earnings in 2016 increased $16 million (4.6%) in the third quarter and decreased $8 million (0.9%) in the first nine months as compared to the corresponding periods in 2015. In the first nine months, the favorable impact from increased sales volume and lower manufacturing costs attributable to deflation in certain commodity unit costs was essentially offset by increased charges related to asset impairments, pension settlements and environmental claims.

Consumer products

Revenues in the third quarter and first nine months of 2016 were approximately $2.8 billion and $8.1 billion, respectively, increases of $677 million (31.3%) and approximately $1.3 billion (18.9%), respectively, compared to the corresponding 2015 periods. The increases reflected the inclusion of Duracell and increases in Forest River’s revenues of 19% in the third quarter and 12% in the first nine months, which were primarily attributable to increased unit sales. Apparel revenues in the third quarter increased $18 million (1.6%) and in the first nine months declined $56 million (1.8%) compared to 2015. The year-to-date decline reflected lower footwear sales and the impact of the disposition of a historically unprofitable operation within Fruit of the Loom in 2015.

Consumer products (Continued)

Pre-tax earnings in the third quarter and first nine months of 2016 increased $112 million (70.0%) and $154 million (27.8%), respectively, compared to the same periods in 2015. The increases in third quarter earnings reflected the impact of the Duracell acquisition as well as increased earnings from Forest River and certain of our apparel businesses. Duracell contributed pre-tax earnings of $39 million in the third quarter of 2016 and $5 million from its acquisition date, reflecting the impact of transition and integration costs. Forest River generated pre-tax earnings increases of 34% in the third quarter and 24% in the first nine months, primarily due to increased unit sales and higher gross margin rates. Earnings of our apparel businesses increased 62% in the third quarter and 29% in the first nine months. The comparative increases were primarily attributable to lower restructuring costs in 2016 and a loss on the disposition of the Fruit of the Loom unprofitable operation in 2015, partly offset by lower earnings in 2016 from our footwear businesses.

Service and retailing

Our service and retailing businesses are comprised of a large group of independently managed businesses engaged in a variety of activities. A summary of revenues and pre-tax earnings of these operations follows. Amounts are in millions.

	Third Quarter								First Nine Months
	Revenues				Pre-tax earnings				Revenues				Pre-tax earnings

Service

Our service businesses offer fractional ownership programs for general aviation aircraft (NetJets) and high technology training to operators of aircraft (FlightSafety). We also distribute electronic components (TTI) and provide electronic distribution services of corporate news, multimedia and regulatory filings (Business Wire). We are a franchisor of quick service restaurants (Dairy Queen), publish newspapers and other publications (Buffalo News and the BH Media Group) and operate a television station in Miami, Florida (WPLG). We also offer third party logistics services that primarily serve the petroleum and chemical industries (Charter Brokerage).

Revenues in the third quarter of 2016 increased $150 million (6.1%) compared to 2015, while revenues for the first nine months of 2016 were relatively unchanged from 2015. NetJets’ comparative revenues increased 3.9% in the third quarter and decreased 6.3% for the first nine months. The increase in NetJets’ third quarter revenues reflected a 2% increase in operating revenues and increased gains from aircraft dispositions, while the decline in revenues for the first nine months was primarily due to lower aircraft sales. TTI’s revenue increases in 2016 were 9.1% in the third quarter and 5.5% for the first nine months and were primarily due to increased sales volume in Europe and through the Internet.

Pre-tax earnings increased $18 million (6.3%) in the third quarter and decreased $93 million (10.1%) in the first nine months of 2016 as compared to corresponding periods in 2015. Pre-tax earnings in the third quarter included increased earnings from NetJets and lower earnings from several of our other service businesses. The year-to-date decline in earnings was primarily due to lower earnings from NetJets, FlightSafety and our newspaper businesses. The decline in NetJets’ earnings for the first nine months was primarily due to increased depreciation expense and lower aircraft sales margins. TTI’s earnings were relatively flat in 2016 as changes in geographic sales mix and price competition produced lower gross margin rates, offsetting the aforementioned revenue increases.

Retailing

Our retailing businesses include four distinct home furnishings retailing businesses (Nebraska Furniture Mart, R.C. Willey, Star Furniture and Jordan’s), which sell furniture, appliances, flooring and electronics. Our retailing businesses also include Berkshire Hathaway Automotive (“BHA”) which was acquired in the first quarter of 2015. BHA currently includes 83 auto dealerships. BHA sells new and pre-owned automobiles and offers repair and other related services and products, and includes two related insurance businesses, two auto auctions and a distributor of automotive fluid maintenance products.

Retailing (Continued)

Our other retailing businesses include three jewelry retailing businesses (Borsheims, Helzberg and Ben Bridge), See’s Candies (confectionary products), Pampered Chef (high quality kitchen tools), Oriental Trading Company (party supplies, school supplies and toys and novelties) and Detlev Louis Motorrad (“Louis”), a retailer of motorcycle accessories based in Germany which was acquired in the second quarter of 2015.

Revenues of our retailing businesses in the third quarter and first nine months of 2016 increased approximately $30 million (0.8%) and $1.7 billion (17.7%), respectively, as compared to the same periods in 2015. The increase in year-to-date revenues reflected the impact of the BHA and Louis acquisitions, which accounted for approximately $1.5 billion of the comparative increase. Revenues of our home furnishings retailers in the third quarter and first nine months of 2016 increased $11 million (1.3%) and $180 million (8.5%), respectively, over 2015, primarily due to new stores opened in 2015 by Nebraska Furniture Mart and Jordan’s. Pre-tax earnings in 2016 from the retail group increased $53 million (58.2%) in the third quarter and $63 million (18.5%) in the first nine months. The increases were primarily attributable to BHA, Louis and our home furnishings businesses.

McLane Company

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 are marked by high sales volumes and very low profit margins and have several significant customers, including Wal-Mart, 7-Eleven and Yum! Brands. A curtailment of purchasing by any of its significant customers could have an adverse impact on McLane’s periodic revenues and earnings.

Revenues for the third quarter and first nine months of 2016 were $12.3 billion and $36.1 billion, respectively, and were relatively unchanged as compared with the corresponding periods in 2015. Year-to-date revenues in 2016 reflected a comparative decline in grocery sales of 2%, attributable to lower unit volume, partly offset by price and mix changes. Year-to-date foodservice revenues increased 3%, primarily due to an overall increase in unit volume. Earnings in the third quarter and first nine months of 2016 were $106 million and $371 million, respectively, unchanged from the third quarter of 2015 and a decrease of $13 million (3%) compared to the first nine months of 2015. Pre-tax earnings in the first nine months of 2015 included a gain of $19 million from the disposition of a subsidiary. Excluding this gain, the operating margin (ratio of earnings to revenues) in the first nine months of 2016 was 1.03%, compared to 1.01% in 2015. The grocery and foodservice business has been and is expected to continue to be highly competitive.

Finance and Financial Products

Our finance and financial products businesses include manufactured housing and finance (Clayton Homes), transportation equipment manufacturing and leasing businesses (UTLX and XTRA, and together, “transportation equipment leasing”), as well as other leasing and financing activities. A summary of revenues and earnings from our finance and financial products businesses follows. Amounts are in millions.

	Third Quarter								First Nine Months

Finance and Financial Products (Continued)

Manufactured housing and finance

Clayton Homes’ revenues in the third quarter and first nine months of 2016 increased $173 million (19%) and $420 million (16%), respectively, compared to 2015. The increases reflected a 27% increase in year-to-date revenues from home sales, due primarily to a 22% increase in units sold and changes in mix. Pre-tax earnings for the third quarter decreased 13% and in the first nine months of 2016 were flat as compared to earnings in the corresponding 2015 periods. Clayton’s earnings in 2016 were negatively impacted by increased losses from insurance claims, increased impairment charges on servicing assets and lower gross sales margins, which partially offset the benefit from the significant increases in unit sales. As of September 30, 2016, approximately 94% of the installment loan portfolio was current in terms of payment status.

Transportation equipment leasing

Transportation equipment leasing revenues in the third quarter and first nine months of 2016 increased $22 million (3.5%) and $160 million (8.7%), respectively, compared to 2015. The increases derived primarily from the acquisition of GE’s railcar services fleet and railcar repair services business in the last half of 2015 and an increase in core fleet size, offset in part by lower utilization rates, lower crane lease demand in North America and reduced volumes in other products and services primarily related to oil and gas markets.

Pre-tax earnings in 2016 were unchanged in the third quarter and increased $76 million (11.6%) in the first nine months compared to 2015. The year-to-date increase was primarily attributable to revenue growth and lower depreciation rates for certain railcars, partially offset by higher railcar repair costs and interest expense on new borrowings from a Berkshire financing subsidiary.

Other

Other finance activities include CORT furniture leasing, our share of the earnings of a commercial mortgage servicing business (“Berkadia”) in which we own a 50% joint venture interest, and interest and dividends from a portfolio of investments. In the first nine months of 2016, other earnings increased $23 million compared to 2015, reflecting increased earnings from investment securities and CORT, partly offset by lower earnings from Berkadia. Other earnings also includes income from interest rate spreads charged on borrowings by a Berkshire financing subsidiary that are used to finance loans and assets held for lease. Corresponding expenses are included in Clayton Homes’ and UTLX’s results. Interest rate spreads charged to these businesses were $55 million in the first nine months of 2016 and $47 million in 2015.

Investment and Derivative Gains/Losses

A summary of investment and derivative gains and losses follows. Amounts are in millions.

	Third Quarter					First Nine Months
	2016		2015			2016		2015
Investment gains/losses	$	3,150	$	8,266		$	5,643	$	8,725
Derivative gains/losses		458		(764	)		(332)		380

Net gains/losses	$	2,347	$	4,877		$	4,593	$	5,920

Investment gains/losses

Investment gains/losses arise primarily from the sale, redemption, or exchange of investments or when investments are carried at fair value with the periodic changes in fair values recorded in earnings. The timing of gains or losses can have a material effect on periodic earnings. Investment gains and losses included in earnings usually have minimal impact on the periodic changes in our consolidated shareholders’ equity since most of our investments are recorded at fair value with the unrealized gains and losses included in shareholders’ equity as a component of accumulated other comprehensive income.

39

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

Investment and Derivative Gains/Losses (Continued)

Investment gains/losses (Continued)

We believe the amount of investment gains/losses included in earnings in any given period typically has little analytical or predictive value. Our decisions to sell securities are not motivated by the impact that the resulting gains or losses will have on our reported earnings. Although we do not consider investment gains and losses as necessarily meaningful or useful in evaluating our periodic results, we are providing information to explain the nature of such gains and losses when reflected in our earnings.

Pre-tax investment gains in the third quarter and first nine months of 2016 were $3.2 billion and $5.6 billion, respectively. Investment gains in the third quarter of 2016 included $2.4 billion from the disposition of our Wrigley preferred stock investment and in the first nine months also included $610 million from the redemption of our Kraft Heinz Preferred Stock investment and $1.1 billion realized in connection with the exchange of shares of P&G common stock for 100% of the common stock of Duracell. Income tax expense allocated to investment gains included a benefit from the reduction of certain deferred income tax liabilities in connection with the exchange of P&G common stock for Duracell. See Notes 8 and 9 to the accompanying Consolidated Financial Statements. In 2015, pre-tax investment gains included non-cash holding gains related to our investment in Kraft Heinz of $6.8 billion in the third quarter, as well as net gains from dispositions of equity and fixed maturity securities of approximately $1.5 billion in the third quarter and $1.9 billion in the first nine months.

Investment gains/losses also included pre-tax other-than-temporary impairment (“OTTI”) charges of $63 million and $26 million in the first nine months of 2016 and 2015, respectively. Although we have periodically recorded OTTI charges in earnings in the past, we continue to hold certain of those securities. If the market values of those securities increase following the date OTTI charges were recorded in earnings, the increases are not reflected in earnings but are instead included in shareholders’ equity as a component of accumulated other comprehensive income. When recorded, OTTI charges have no impact whatsoever on the asset values otherwise recorded in our Consolidated Balance Sheets or on our consolidated shareholders’ equity. In addition, the recognition of such losses in earnings rather than in accumulated other comprehensive income does not necessarily indicate that sales are planned and ultimately sales may not occur for a number of years. Furthermore, the recognition of an OTTI charge does not necessarily indicate that the loss in value of the security is permanent or that the market price of the security will not subsequently increase to and ultimately exceed our original cost.

As of September 30, 2016, gross unrealized losses on our investments in equity and fixed maturity securities determined on an individual purchase lot basis were approximately $1.4 billion, of which $941 million pertained to our investment in IBM common stock. We concluded that such losses were temporary. We consider several factors in determining whether or not impairments are deemed to be other than temporary, including the current and expected long-term business prospects and if applicable, the creditworthiness of the issuer, our ability and intent to hold the investment until the price recovers and the length of time and relative magnitude of the price decline.

Derivative gains/losses

Derivative gains/losses primarily represented the changes in fair value of our equity index put option contract liabilities. Periodic changes in the fair values of liabilities reflected in earnings can be significant, reflecting the volatility of underlying equity markets and from changes in the inputs used to measure such liabilities.

In 2016, our equity index put option contracts produced pre-tax gains of $458 million in the third quarter and pre-tax losses of $421 million for the first nine months. In each period, these gains and losses were primarily due to changes in the index values and interest rates and the passage of time. In 2015, our equity index put option contracts produced pre-tax losses of $802 million in the third quarter and pre-tax gains of $371 million in the first nine months. In the third quarter of 2015, the losses were driven by lower index prices and increased expected volatility assumptions, which produced an increase in the fair value of our liabilities. The third quarter losses offset much of the gains realized in the first six months of 2015, which were primarily attributable to higher index prices, a stronger U.S. Dollar and increased interest rates. As of September 30, 2016, equity index put option intrinsic values were approximately $1.6 billion and our recorded liabilities at fair value were approximately $4.0 billion. Our ultimate payment obligations, if any, under our equity index put option contracts will be determined as of the contract expiration dates (beginning in 2018), and will be based on the intrinsic value as defined under the contracts.

In July 2016, our remaining credit default contract was terminated by mutual agreement with the counterparty and we paid $195 million upon termination. This contract produced pre-tax earnings of $89 million in the first nine months of 2016. We have no further exposure to losses under credit default contracts.

Other

A summary of after-tax other earnings which include corporate income (including income from our investments in Kraft Heinz), expenses and income taxes not allocated to operating businesses is summarized below. Amounts are in millions.

	Third Quarter				First Nine Months
	2016		2015		2016		2015
Kraft Heinz earnings	$	146	$	115	$	552	$	315
Acquisition accounting expenses		(317)		(199)		(550)		(400)
Corporate interest expense		(116)		(41)		(297)		(216)
Other		25		—		(15)		(6)
Net earnings attributable to Berkshire Hathaway shareholders	$	(262)	$	(125)	$	(310)	$	(307)

Our earnings in 2016 from our investments in Kraft Heinz included lower dividends on the Preferred Stock, which was redeemed in June 2016, and increased equity method earnings from our common stock investment. Our earnings, after allocated Berkshire corporate income taxes, were $146 million in the third quarter and $552 million in the first nine months of 2016. In 2015, these investments produced earnings of $115 million in the third quarter and $315 million for the first nine months.

After-tax corporate interest expense was $116 million in the third quarter and $297 million for the first nine months of 2016 and $41 million and $216 million, respectively, in the comparable 2015 periods. The increases in 2016 reflected the impact of increased average borrowings. The variations in comparative periodic after-tax corporate interest expense also reflected the impact of foreign exchange gains and losses with respect to Euro denominated debt issued by Berkshire in March 2015 (€3.0 billion par) and March 2016 (€2.75 billion par). Corporate interest included after-tax foreign currency exchange losses of $48 million in the third quarter and $107 million in the first nine months of 2016 and $4 million and $106 million, respectively, in the comparable 2015 periods. Relatively minor changes in the U.S. Dollar/Euro exchange rate can produce significant gains or losses given the current level of our Euro-denominated borrowings.

Also included in other earnings are charges related to the application of the acquisition method in connection with Berkshire’s business acquisitions. Such charges were primarily from the amortization of intangible assets recorded in connection with those business acquisitions. These charges (after-tax) were $317 million and $550 million in the third quarter and first nine months of 2016, respectively, compared to $199 million and $400 million, respectively, in the comparable periods in 2015.

Financial Condition

Our balance sheet continues to reflect significant liquidity and a strong capital base. Our consolidated shareholders’ equity at September 30, 2016 was $269.3 billion, an increase of $13.7 billion since December 31, 2015. Net earnings attributable to Berkshire shareholders in the first nine months of 2016 were $17.8 billion. At September 30, 2016, our insurance and other businesses held cash and cash equivalents of $68.3 billion, and investments (excluding our investment in Kraft Heinz) of $140.8 billion. In June 2016, we received $8.32 billion in connection with the redemption of our Kraft Heinz Preferred Stock investment.

In January 2016, we used cash of approximately $32.1 billion to fund the acquisition of PCC, which we funded through a combination of cash on hand and $10 billion borrowed under a new 364-day revolving credit agreement. In March 2016, we issued €2.75 billion and $5.5 billion of senior unsecured notes. The proceeds were used in the repayment of all outstanding borrowings under the aforementioned revolving credit agreement. In June, the revolving credit agreement was terminated. See Note 16 to the accompanying Consolidated Financial Statements. In August 2016, we issued $750 million of senior unsecured notes to replace $750 million of maturing notes. Over the next twelve months, $1.1 billion of parent company senior notes will mature.

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

Financial Condition (Continued)

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. In the first nine months of 2016, aggregate capital expenditures of these businesses were approximately $6.4 billion, including $3.5 billion by BHE and $2.9 billion by BNSF. Forecasted capital expenditures of the two businesses for the remainder of 2016 approximate $2.5 billion. Future capital expenditures are expected to be funded from cash flows from operations and debt issuances.

BNSF’s outstanding debt was approximately $22.2 billion as of September 30, 2016, an increase of $429 million from December 31, 2015. Outstanding borrowings of BHE and its subsidiaries, excluding its borrowings from Berkshire insurance subsidiaries, were approximately $36.6 billion as of September 30, 2016, an increase of $643 million from December 31, 2015. 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 or BHE or any of their subsidiaries.

Finance and financial products assets were approximately $41.9 billion as of September 30, 2016, an increase of approximately $2.9 billion since December 31, 2015. Finance assets at September 30, 2016 primarily consisted of loans and finance receivables and various types of property held for lease, as well as significant cash and cash equivalents, which included the proceeds of approximately $4.6 billion from the sale of our Wrigley preferred stock investment in September.

Finance and financial products liabilities were approximately $21.1 billion as of September 30, 2016, an increase of approximately $3.9 billion compared to December 31, 2015. The year-to-date increase was primarily attributable to new debt issued by Berkshire Hathaway Finance Corporation (“BHFC”), including $3.5 billion of senior notes issued in March. See Note 16 to the accompanying Consolidated Financial Statements. The proceeds were used to fund loans originated and acquired by Clayton Homes and to fund a portion of existing assets held for lease by our rail tank car leasing business, UTLX. Over the next twelve months, $2.8 billion of BHFC senior notes will mature.

Contractual Obligations

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 reflected 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 pertain to the acquisition of goods or services in the future, such as minimum rentals under operating leases and certain purchase obligations, and are not currently reflected in the financial statements. Such obligations will be reflected in future periods as the goods are delivered or services provided.

During the first nine months of 2016, we issued new term debt and assumed debt through the PCC business acquisition. Future payments of principal and interest related to such borrowings are summarized as follows (in millions): 2016 - $225; 2017 - $424; 2018 - $3,905; 2019 - $3,362; and 2020 and after - $15,756. Except as otherwise disclosed in this Quarterly Report, our contractual obligations as of September 30, 2016 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, 2015.

Critical Accounting Policies

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 currently 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, 2015.

Our Consolidated Balance Sheet as of September 30, 2016 includes estimated liabilities for unpaid losses from property and casualty insurance and reinsurance contracts of approximately $75.5 billion. Due to the inherent uncertainties in the process of establishing these liabilities, the actual ultimate claim liabilities will likely differ from the currently recorded amounts. A small percentage change in estimates of this magnitude could have a material effect on our 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.

42

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

Critical Accounting Policies (Continued)

Our Consolidated Balance Sheet as of September 30, 2016 includes goodwill of acquired businesses of approximately $79 billion. We evaluate goodwill for impairment at least annually and we conducted our most recent annual review during the fourth quarter of 2015. Although we believe that the goodwill reflected in the Consolidated Balance Sheet is not impaired, goodwill may subsequently become impaired as a result of changes in facts and circumstances that adversely affect the valuations of the reporting units. A goodwill impairment charge could have a material effect on periodic earnings.

Our Consolidated Balance Sheets include significant derivative contract liabilities with respect to our long-duration equity index put option contracts. The fair values recorded for these liabilities are based on valuation models that utilize various inputs and assumptions that we believe are used by market participants. We further believe that fair values based on such models are inherently subjective and the values in an actual transaction may differ significantly from the model values. Changes in the assumptions utilized within the valuation models may have a significant effect on recorded fair values and periodic earnings.

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

Forward-Looking 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, losses realized from derivative contracts, the occurrence of one or more catastrophic events, such as an earthquake, hurricane or act of terrorism that causes losses insured by our insurance subsidiaries and/or losses to our business operations, changes in laws or regulations affecting our insurance, railroad, utilities and energy and finance subsidiaries, changes in federal income tax 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 30, 2016, 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, 2015.

Item 4. Controls and Procedures

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.

Part II Other Information

Item 1. Legal Proceedings

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.

Item 1A. Risk Factors

Our significant business risks are described in Item 1A to Form 10-K for the year ended December 31, 2015 to which reference is made herein.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds and Issuer Repurchases of Equity Securities

Berkshire’s Board of Directors (“Berkshire’s Board”) has approved a common stock repurchase program under which Berkshire may repurchase its Class A and Class B shares at prices no higher than a 20% premium over the book value of the shares. Berkshire may repurchase shares in the open market or through privately negotiated transactions. Berkshire’s Board authorization does not specify a maximum number of shares to be repurchased. However, repurchases will not be made if they would reduce Berkshire’s consolidated cash and cash equivalents below $20 billion. The repurchase program is expected to continue indefinitely and the amount of repurchases will depend entirely upon the level of cash available, the attractiveness of investment and business opportunities either at hand or on the horizon, and the degree of discount of the market price relative to management’s estimate of intrinsic value. The repurchase program does not obligate Berkshire to repurchase any dollar amount or number of Class A or Class B shares and there is no expiration date to the program. There were no share repurchases under the program in the first nine months of 2016.

Item 3. Defaults Upon Senior Securities

Information regarding the Company’s mine safety violations and other legal matters disclosed in accordance with Section 1503(a) of the Dodd-Frank Reform Act is included in Exhibit 95 to this Form 10-Q.

MINE SAFETY VIOLATIONS AND OTHER LEGAL MATTER DISCLOSURES

PURSUANT TO SECTION 1503(a) OF THE DODD-FRANK WALL STREET

REFORM AND CONSUMER PROTECTION ACT

PacifiCorp and its subsidiaries operate coal mines and coal processing facilities and Acme Brick and its affiliates operate clay, shale and limestone excavation facilities (collectively, the “mining facilities”) that are regulated by the Federal Mine Safety and Health Administration (“MSHA”) under the Federal Mine Safety and Health Act of 1977 (the “Mine Safety Act”). MSHA inspects mining facilities on a regular basis. The total number of reportable Mine Safety Act citations, orders, assessments and legal actions for the three-month period ended September 30, 2016 are summarized in the table below and are subject to contest and appeal. The severity and assessment of penalties may be reduced or, in some cases, dismissed through the contest and appeal process. Amounts are reported regardless of whether PacifiCorp or Acme has challenged or appealed the matter. Clay and other reserves that are not yet mined and mines that are closed or idled are not included in the information below as no reportable events occurred at those locations during the three-month period ended September 30, 2016. PacifiCorp and Acme have not received any notice of a pattern, or notice of the potential to have a pattern, of violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to the cause and effect of coal or other mine health or safety hazards under Section 104(e) of the Mine Safety Act during the three-month period ended September 30, 2016.

(2) For alleged failure to totally abate the subject matter of a Mine Safety Act Section 104(a) citation within the period specified in the citation.

(3) For alleged unwarrantable failure (i.e., aggravated conduct constituting more than ordinary negligence) to comply with a mandatory health or safety standard.

(4) For alleged flagrant violations (i.e., reckless or repeated failure to make reasonable efforts to eliminate a known violation of a mandatory health or safety standard that substantially and proximately caused, or reasonably could have been expected to cause, death or serious bodily injury).

(5) For the existence of any condition or practice in a coal or other mine which could reasonably be expected to cause death or serious physical harm before such condition or practice can be abated.

(6) Amounts include six contests of proposed penalties under Subpart C and two contests of citations or orders under Subpart B and one labor-related complaint under Subpart E of the Federal Mine Safety and Health Review Commission’s procedural rules. The pending legal actions are not exclusive to citations, notices, orders and penalties assessed by MSHA during the reporting period.

Accounting Policies [Abstract]

General

Note 1. General

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

Financial information in this Quarterly Report reflects any 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. Variations in the amount and timing of investment gains/losses can cause significant variations in periodic net earnings. Investment gains/losses are recorded when investments are disposed or are other-than-temporarily impaired. In addition, changes in the fair values of liabilities associated with derivative contracts can cause significant variations in periodic net earnings.

Accounting Changes and Error Corrections [Abstract]

New accounting pronouncements

Note 2. New accounting pronouncements

In May 2014, the FASB issued ASU 2014-09 “Revenue from Contracts with Customers.” ASU 2014-09 applies to contracts with customers, excluding, most notably, insurance and leasing contracts. ASU 2014-09 prescribes a framework in accounting for revenues from contracts within its scope, including (a) identifying the contract, (b) identifying the performance obligations under the contract, (c) determining the transaction price, (d) allocating the transaction price to the identified performance obligations and (e) recognizing revenues as the identified performance obligations are satisfied. ASU 2014-09 also prescribes additional financial statement presentations and disclosures. We currently expect to adopt ASU 2014-09 as of January 1, 2018, under the modified retrospective method where the cumulative effect is recognized at the date of initial application. Our evaluation of ASU 2014-09 is ongoing and not complete. The FASB has issued and may issue in the future, interpretative guidance, which may cause our evaluation to change. While we anticipate some changes to revenue recognition for certain customer contracts, we do not currently believe ASU 2014-09 will have a material effect on our Consolidated Financial Statements.

In May 2015, the FASB issued ASU 2015-09 “Financial Services—Insurance—Disclosures about Short-Duration Contracts,” which requires additional disclosures in annual and interim reporting periods by insurance entities regarding liabilities for unpaid claims and claim adjustment expenses, and changes in assumptions or methodologies for calculating such liabilities. ASU 2015-09 is effective for annual periods beginning after December 15, 2015 and interim periods beginning after December 15, 2016. We continue to evaluate the effect adopting this standard will have on the disclosures in our Consolidated Financial Statements.

In January 2016, the FASB issued ASU 2016-01 “Financial Instruments—Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 generally requires that equity investments (excluding equity method investments) be measured at fair value with changes in fair value recognized in net income. Under existing GAAP, changes in fair value of available-for-sale equity investments are recorded in other comprehensive income. Given the current magnitude of our equity investments, the adoption of ASU 2016-01 will likely have a significant impact on the periodic net earnings reported in our Consolidated Statement of Earnings, although it will likely not significantly impact our comprehensive income or shareholders’ equity. ASU 2016-01 is effective for annual and interim periods beginning after December 15, 2017, with the cumulative effect of the adoption made to the balance sheet as of the date of adoption. Thus, the adoption will result in a reclassification of the related accumulated unrealized appreciation currently included in accumulated other comprehensive income to retained earnings, with no impact on Berkshire shareholders’ equity.

In February 2016, the FASB issued ASU 2016-02 “Leases.” ASU 2016-02 requires a lessee to recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term, along with additional qualitative and quantitative disclosures. ASU 2016-02 is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the effect this standard will have on our Consolidated Financial Statements.

In June 2016, the FASB issued ASU 2016-13 “Financial Instruments—Credit Losses,” which provides for the recognition and measurement at the reporting date of all expected credit losses for financial assets held at amortized cost and available-for-sale debt securities. Currently credit losses are recognized and measured when such losses become probable based on the prevailing facts and circumstances. ASU 2016-13 is effective for reporting periods beginning after December 15, 2019. We are currently evaluating the effect this standard will have on our Consolidated Financial Statements.

Business Combinations [Abstract]

Significant business acquisitions

Note 3. Significant business acquisitions

Our long-held acquisition strategy is to acquire businesses at sensible prices that have consistent earning power, good returns on equity and able and honest management. On August 8, 2015, Berkshire entered into a definitive agreement with Precision Castparts Corp. (“PCC”) to acquire all outstanding PCC shares of common stock for $235 per share in cash. The acquisition was completed on January 29, 2016. The aggregate consideration paid was approximately $32.7 billion, which included the value of PCC shares we already owned. We funded the acquisition with a combination of existing cash balances and proceeds from a short-term credit facility.

PCC is a worldwide, diversified manufacturer of complex metal components and products. It serves the aerospace, power and general industrial markets. PCC is a market leader in manufacturing complex structural investment castings and forged components for aerospace markets, machined airframe components and highly engineered critical fasteners for aerospace applications, and in manufacturing airfoil castings for the aerospace and industrial gas turbine markets. PCC also is a leading producer of titanium and nickel superalloy melted and mill products for the aerospace, chemical processing, oil and gas and pollution control industries, and manufactures extruded seamless pipe, fittings and forgings for power generation and oil and gas applications.

In November 2014, Berkshire entered into a definitive agreement with The Procter & Gamble Company (“P&G”) to acquire the Duracell business from P&G. The transaction closed on February 29, 2016. Duracell is a leading manufacturer of high-performance alkaline batteries and is an innovator in renewable power and wireless charging technologies. Pursuant to the agreement, we received a recapitalized Duracell Company in exchange for shares of P&G common stock held by Berkshire subsidiaries which had a fair value of approximately $4.2 billion.

Financial results attributable to these business acquisitions are included in our Consolidated Financial Statements beginning on their respective acquisition dates. The acquisition date fair values of certain assets and liabilities, particularly property, plant and equipment and intangible assets, and related estimated useful lives are provisional and are subject to revision as the related valuations are completed. We expect such values will be finalized as of December 31, 2016. Goodwill from these acquisitions is not amortizable for income tax purposes. Preliminary fair values of identified assets acquired and liabilities assumed and residual goodwill of PCC and Duracell at their respective acquisition dates are summarized in the table that follows (in millions).

As of September 30, 2016 and December 31, 2015, we concluded that the unrealized losses shown in the tables above were temporary. Our conclusions were based on: (a) our ability and intent to hold the securities to recovery; (b) our assessment that the underlying business and financial condition of the issuers was favorable; (c) our opinion that the relative price declines were not significant; and (d) our belief that market prices will increase to and exceed our cost. As of September 30, 2016 and December 31, 2015, unrealized losses on equity securities in a continuous unrealized loss position for more than twelve months were $995 million and $989 million, respectively.

Unrealized losses at September 30, 2016 included $941 million related to our investment in IBM common stock of which $855 million had been in a continuous unrealized loss position for more than twelve months. Unrealized losses represented 7% of our cost. IBM continues to be profitable and generate significant cash flows. We currently do not intend to dispose of our IBM common stock and we expect that the fair value of this investment will recover and ultimately exceed our cost.

During 2008, we purchased $2.1 billion of Wrigley preferred stock that was acquired pursuant to a shareholder agreement in conjunction with Mars Incorporated’s acquisition of Wrigley. Pursuant to certain put and call provisions in the shareholder agreement, up to 50% of our original investment was redeemable over a 90-day period that was scheduled to begin on October 6, 2016. On August 8, 2016, we entered into a stock purchase agreement with Mars, under which Mars agreed to acquire all of the Wrigley preferred stock for approximately $4.56 billion, which included a prorated dividend that would have otherwise been payable on October 6, 2016. The transaction was completed on September 27, 2016.

We own 3,000,000 shares of Series A Cumulative Convertible Perpetual Preferred Stock of Dow (“Dow Preferred”) with a liquidation value of $1,000 per share. Each share of the Dow Preferred is convertible into 24.201 shares of Dow common stock (equivalent to a conversion price of $41.32 per share). Dow currently has the option to cause some or all of the Dow Preferred to be converted into Dow common stock at the then applicable conversion rate, if the New York Stock Exchange closing price of its common stock exceeds $53.72 per share for any 20 trading days within a period of 30 consecutive trading days ending the day before Dow exercises its option. The Dow Preferred is entitled to dividends at a rate of 8.5% per annum.

We own 50,000 shares of 6% Non-Cumulative Perpetual Preferred Stock of BAC (“BAC Preferred”) with a liquidation value of $100,000 per share and warrants to purchase 700,000,000 shares of common stock of BAC (“BAC Warrants”). The BAC Preferred is redeemable at the option of BAC beginning on May 7, 2019 at a redemption price of $105,000 per share (or $5.25 billion in aggregate). The BAC Warrants expire in 2021 and are exercisable for an additional aggregate cost of $5 billion ($7.142857/share).

We own Class A 9% Cumulative Compounding Perpetual Preferred Shares of RBI (“RBI Preferred”) having a stated value of $3 billion. RBI, domiciled in Canada, is the ultimate parent company of Burger King and Tim Hortons. The RBI Preferred is entitled to dividends on a cumulative basis of 9% per annum plus an additional amount, if necessary, to produce an after-tax yield to Berkshire as if the dividends were paid by a U.S.-based company. The RBI Preferred is redeemable at the option of RBI beginning on December 12, 2017. If not redeemed prior to December 12, 2024, we can cause RBI to redeem the RBI Preferred. In either case, the redemption price will be 109.9% of the stated value of such shares.

On June 7, 2013, Berkshire and an affiliate of the global investment firm 3G Capital (such affiliate, “3G”), each made equity investments in H.J. Heinz Holding Corporation (“Heinz Holding”), which, together with debt financing obtained by Heinz Holding, was used to acquire H. J. Heinz Company (“Heinz”). Berkshire’s initial investments consisted of 425 million shares of Heinz Holding common stock, warrants, which were exercised in June 2015, to acquire approximately 46 million additional shares of common stock at one cent per share, and cumulative compounding preferred stock (“Preferred Stock”) with a liquidation preference of $8 billion. The aggregate cost of our investments was $12.25 billion. 3G also acquired 425 million shares of Heinz Holding common stock for $4.25 billion. On June 7, 2016, our Preferred Stock investment was redeemed for cash of $8.32 billion. Prior to its redemption, the Preferred Stock was entitled to dividends at 9% per annum.

On July 1, 2015, Berkshire acquired 262.9 million shares of newly issued common stock of Heinz Holding for $5.26 billion and 3G acquired 237.1 million shares of newly issued common stock for $4.74 billion. Immediately thereafter, Heinz Holding executed a reverse stock split at a rate of 0.443332 of a share for each share.

On July 2, 2015, Heinz Holding acquired Kraft Foods Group, Inc. (“Kraft”). Upon completion of the acquisition, Heinz Holding was renamed The Kraft Heinz Company (“Kraft Heinz”). Kraft Heinz is one of the 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, in the world. Kraft Heinz’s leading iconic brands include Kraft, Heinz, ABC, Capri Sun, Classico, Jell-O, Kool-Aid, Lunchables, Maxwell House, Ore-Ida, Oscar Mayer, Philadelphia, Planters, Plasmon, Quero, Weight Watchers Smart Ones and Velveeta.

In connection with Heinz Holding’s acquisition of Kraft, Kraft shareholders received one share of newly issued Heinz Holding common stock for each share of Kraft common stock and a special cash dividend of $16.50 per share. Following the issuance of these additional shares, Berkshire and 3G together owned approximately 51% of the outstanding Kraft Heinz common stock, with Berkshire owning approximately 26.8% and 3G owning 24.2%. We account for our investment in Kraft Heinz common stock on the equity method. Under the equity method, the issuance of shares by an investee is accounted for by the investor as if the investor had sold a proportionate share of its investment. As a result, we recorded a non-cash pre-tax holding gain of approximately $6.8 billion in the third quarter of 2015, representing the excess of the fair value of Kraft Heinz common stock at the date of the merger over our carrying value associated with the reduction in our ownership.

A summary of our investments in Kraft Heinz follows (in millions).

	Carrying Value
	September 30,  2016		December 31,  2015
Common stock		$15,711		$15,714
Preferred Stock		—		7,710
		$15,711		$23,424

Our equity method earnings on the common stock and dividends earned on the Preferred Stock in the first nine months of 2016 and 2015 were $851 million and $329 million, respectively, and are included in interest, dividend and other investment income in our Consolidated Statements of Earnings. Preferred Stock dividends received in the first nine months of 2016 were $180 million. In 2015, Preferred Stock dividends received were $180 million in the third quarter and $540 million in the first nine months.

Income taxes

Note 8. Income taxes

Our consolidated effective income tax rates for the third quarter and first nine months of 2016 were 30.3% and 25.8%, respectively. In 2015, our effective income tax rates were 32.3% for the third quarter and 31.6% for the first nine months. Our effective income tax rate normally reflects benefits from the recurring impact of (a) dividends received deductions applicable to certain investments in equity securities, (b) income production tax credits from wind-powered electricity generation placed in service in the U.S. and (c) lower income tax rates applicable to earnings of certain foreign subsidiaries.

As discussed in Notes 3 and 9 to these Consolidated Financial Statements, on February 29, 2016, we exchanged our long-held investment in P&G common stock for the common stock of Duracell. This exchange produced a pre-tax gain of $1.1 billion for financial reporting purposes. The exchange transaction was structured as a tax-free reorganization under the Internal Revenue Code. As a result, no income taxes are currently payable on the excess of the fair value of the business received over the tax basis of the P&G shares exchanged and we recorded a one-time reduction of certain deferred income tax liabilities (approximately $750 million) that were recorded in 2005 in connection with our exchange of The Gillette Company common stock for P&G common stock upon the merger of those two companies. The P&G/Duracell exchange produced a 4.7 percentage point reduction in our consolidated effective income tax rate for the first nine months of 2016.

	$	3,150	$	8,266	$	5,643	$	8,725

Gains from sales and redemptions of equity securities in 2016 included gains of approximately $2.4 billion from the disposition of our investment in Wrigley preferred stock in the third quarter, and in the first nine months also included $610 million from the redemption of our investment in Kraft Heinz Preferred Stock and a non-cash holding gain of approximately $1.1 billion from the exchange of our P&G common stock in connection with the acquisition of Duracell. The non-cash gain from the P&G/Duracell exchange represented the excess of the fair value of net assets of Duracell over the cost basis of the P&G stock exchanged. Gains from sales and redemptions of equity securities in the third quarter and first nine months of 2015 included a non-cash holding gain of approximately $6.8 billion in connection with our investment in Kraft Heinz common stock.

We record investments in equity and fixed maturity securities classified as available-for-sale at fair value and record the difference between fair value and cost in other comprehensive income. Other-than-temporary impairment losses recognized in earnings represent reductions in the cost basis of the investment, but not the fair value. Accordingly, such losses that are included in earnings are generally offset by a credit to other comprehensive income, producing no net effect on shareholders’ equity as of the balance sheet date.

Derivative contracts

Note 14. Derivative contracts

Derivative contracts have been entered into primarily through our finance and financial products and our utilities and energy businesses. During 2016, derivative contracts of our finance and financial products businesses consisted of equity index put option contracts and a credit default contract. A summary of the liabilities and related notional values of these contracts follows (in millions).

	September 30, 2016					December 31, 2015
	Liabilities		Notional   Value			Liabilities		Notional   Value
Equity index put options	$	3,973	$	27,982	(1)	$	3,552	$	27,722	(1)
Credit default (2)		—		—			284		7,792
	$	3,973				$	3,836

⁽¹⁾ Represents the aggregate undiscounted amounts payable assuming that the value of each index is zero at each contract’s expiration date. Certain of these contracts are denominated in foreign currencies. Notional amounts are based on the foreign currency exchange rates as of each balance sheet date.

⁽²⁾  In July 2016, our remaining credit default contract was terminated by mutual agreement with the counterparty. We no longer have any exposure to losses under credit default contracts.

The derivative contracts of our finance and financial products businesses are recorded at fair value and the changes in the fair values of such contracts are reported in earnings as derivative gains/losses. We entered into these contracts with the expectation that the premiums received would exceed the amounts ultimately paid to counterparties. A summary of the derivative gains (losses) included in our Consolidated Statements of Earnings follows (in millions).

	Third Quarter				First Nine Months
	2016		2015		2016			2015
Equity index put options	$	458	$	(802)	$	(421	)	$	371
Credit default		—		38		89			9
	$	458	$	(764)	$	(332	)	$	380

The equity index put option contracts are European style options written between 2004 and 2008 on four major equity indexes. These contracts will expire between June 2018 and January 2026. Future payments, if any, under any given contract will be required if the prevailing index value is below the contract strike price at the expiration date. We received the premiums on these contracts at the inception dates and therefore we have no 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) of our equity index put option contracts was approximately $1.6 billion at September 30, 2016 and $1.1 billion at December 31, 2015. However, these contracts may not be unilaterally terminated or fully settled before the expiration dates. Therefore, the ultimate amount of cash basis gains or losses on these contracts will not be determined for several years. The remaining weighted average life of all contracts was approximately 4.2 years at September 30, 2016.

A limited number of our equity index put option contracts contain collateral posting requirements with respect to changes in the fair value or intrinsic value of the contracts and/or a downgrade of Berkshire’s credit ratings. As of September 30, 2016, we did not have any collateral posting requirements. If Berkshire’s credit ratings (currently AA from Standard & Poor’s and Aa2 from Moody’s) are downgraded below either A- by Standard & Poor’s or A3 by Moody’s, collateral of up to $1.1 billion could be required to be posted.

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. Derivative instruments, including forward purchases and sales, futures, swaps and options, are used to manage a portion of these price risks. Derivative contract assets are included in other assets and were $105 million as of September 30, 2016 and $103 million as of December 31, 2015. Derivative contract liabilities are included in accounts payable, accruals and other liabilities and were $198 million as of September 30, 2016 and $237 million as of December 31, 2015. Net derivative contract assets or liabilities that are probable of recovery through rates of our regulated utilities are offset by regulatory liabilities or assets. Unrealized gains or losses on contracts accounted for as cash flow or fair value hedges are recorded in other comprehensive income or in net earnings, as appropriate.

			$	27,514	$	14,599

On January 8, 2016, Berkshire entered into a $10 billion 364-day revolving credit agreement. In connection with the PCC acquisition, Berkshire borrowed $10 billion under the credit agreement. In March 2016, Berkshire issued €2.75 billion in senior unsecured notes consisting of €1.0 billion of 0.50% notes due in 2020, €1.0 billion of 1.30% notes due in 2024 and €750 million of 2.15% notes due in 2028. Berkshire also issued $5.5 billion in senior unsecured notes consisting of $1.0 billion of 2.20% notes due in 2021, $2.0 billion of 2.75% notes due in 2023 and $2.5 billion of 3.125% notes due in 2026. The proceeds from these debt issues were used in the repayment of all outstanding borrowings under the aforementioned credit agreement. In June 2016, the revolving credit agreement was terminated. In August 2016, Berkshire issued $750 million in senior unsecured notes consisting of $500 million of 1.15% notes due in 2018 and $250 million of floating rate notes due in 2018, to replace $750 million of maturing debt. Other subsidiary borrowings at September 30, 2016 included $4.7 billion attributable to PCC.

			$	58,811	$	57,739

BHE subsidiary debt represents amounts issued pursuant to separate financing agreements. Substantially all of the assets of certain BHE subsidiaries are, or may be, pledged or encumbered to support or otherwise secure debt. These borrowing arrangements generally contain various covenants including, but not limited to, leverage ratios, interest coverage ratios and debt service coverage ratios. BNSF’s borrowings are primarily senior unsecured debentures. In May 2016, BNSF issued $750 million of 3.9% debentures due in 2046. As of September 30, 2016, BNSF and 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.

In March 2016, BHFC issued $3.5 billion of senior notes consisting of $750 million of 1.45% notes due in 2018, $1.0 billion of floating rate notes due in 2018, $1.25 billion of 1.70% notes due in 2019 and $500 million of floating rate notes due in 2019. In August 2016, BHFC issued $1.25 billion of senior notes consisting of $1 billion of 1.30% notes due in 2019 and $250 million of floating rate notes due in 2019, primarily to replace $1 billion of maturing debt. The borrowings of BHFC, a wholly owned finance subsidiary of Berkshire, are fully and unconditionally guaranteed by Berkshire.

As of September 30, 2016, our subsidiaries also had unused lines of credit and commercial paper capacity aggregating approximately $8.2 billion to support short-term borrowing programs and provide additional liquidity. Such unused lines of credit included about $4.0 billion related to BHE and its subsidiaries. In addition to BHFC’s borrowings, Berkshire guarantees certain other subsidiary borrowings, which aggregated approximately $3.2 billion at September 30, 2016. 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 present and future payment obligations.

The fair values of substantially all of our financial instruments were measured using market or income approaches. Considerable judgment may be required in interpreting market data used to develop the estimates of fair value. Accordingly, the fair values presented are not necessarily indicative of the amounts that could be realized in an actual current market exchange. The use of alternative market assumptions and/or estimation methodologies may have a material effect on the estimated fair value. The hierarchy for measuring fair value consists of Levels 1 through 3, which are described below.

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

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

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

Reconciliations of assets and liabilities measured and carried at fair value on a recurring basis with the use of significant unobservable inputs (Level 3) for the nine months ending September 30, 2016 and 2015 follow (in millions).

Gains and losses included in earnings are included as components of investment gains/losses, derivative gains/losses or other revenues, as appropriate and are primarily related to changes in the fair values of derivative contracts and settlement transactions. Gains and losses included in other comprehensive income primarily represent the net change in unrealized appreciation of investments. In the third quarter of 2016, our investment in Wrigley preferred stock was redeemed.

Quantitative information as of September 30, 2016, with respect to assets and liabilities measured and carried at fair value on a recurring basis with the use of significant unobservable inputs (Level 3) follows (in millions).

	Fair   Value		Principal Valuation Techniques	Unobservable Inputs		Weighted Average
Other investments:
Preferred stocks	$	11,615	Discounted cash flow		Expected duration		6 years
					Discount for transferability restrictions and subordination		159 basis points
Common stock warrants		5,502	Warrant pricing model		Discount for transferability and hedging restrictions		7%
Net derivative liabilities:
Equity index put options		3,973	Option pricing model		Volatility		21%

Other investments consist of perpetual preferred stocks and common stock warrants that we acquired in private placement transactions. These investments are subject to contractual restrictions on transferability and may contain provisions that prevent us from economically hedging our investments. In applying discounted estimated cash flow techniques in valuing the perpetual preferred stocks, we made assumptions regarding the expected durations of the investments, as the issuers may have the right to redeem or convert these investments. We also made estimates regarding the impact of subordination, as the preferred stocks have a lower priority in liquidation than debt instruments of the issuers. In valuing the common stock warrants, we used a warrant valuation model. While most of the inputs to the model are observable, we are subject to the aforementioned contractual restrictions and we have applied discounts with respect to such restrictions. Increases or decreases to these inputs would result in decreases or increases to the fair values of the investments.

Our equity index put option 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 and many contracts have relatively long durations. For these and other reasons, we classified these contracts as Level 3. The methods we use to value these contracts are those that we believe market participants would use in determining exchange prices with respect to our contracts.

We value equity index put option contracts based on the Black-Scholes option valuation model. Inputs to this model include the index price, contract duration and dividend and interest rates (including a Berkshire non-performance input) which are observable. However, we believe that the valuation of long-duration options using any model is inherently subjective and, given the lack of observable transactions and prices, acceptable values may be subject to wide ranges. Volatility inputs represent our expectations, which consider the remaining duration of each contract and assume that the contracts will remain outstanding until the expiration dates without offsetting transactions occurring in the interim. Increases or decreases in the volatility inputs will produce increases or decreases in the fair values of the liabilities.

Each Class A common share is entitled to one vote per share. Class B common stock possesses dividend and distribution rights equal to one-fifteen-hundredth (1/1,500) of such rights of Class A common stock. Each Class B common share possesses voting rights 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 1,644,031 shares outstanding as of September 30, 2016 and 1,643,393 shares outstanding as of December 31, 2015. In addition to our common stock, 1,000,000 shares of preferred stock are authorized, but none are issued.

Berkshire’s Board of Directors (“Berkshire’s Board”) has approved a common stock repurchase program under which Berkshire may repurchase its Class A and Class B shares at prices no higher than a 20% premium over the book value of the shares. Berkshire may repurchase shares in the open market or through privately negotiated transactions. Berkshire’s Board authorization does not specify a maximum number of shares to be repurchased. However, repurchases will not be made if they would reduce Berkshire’s consolidated cash and cash equivalent holdings below $20 billion. The repurchase program does not obligate Berkshire to repurchase any dollar amount or number of Class A or Class B shares and there is no expiration date to the program.

Contingencies and Commitments

Note 20. Contingencies and Commitments

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

We own a 50% interest in a joint venture, Berkadia Commercial Mortgage LLC (“Berkadia”), with Leucadia National Corporation (“Leucadia”) owning the other 50% interest. Berkadia is a servicer of commercial real estate loans in the U.S., performing primary, master and special servicing functions for U.S. government agency programs, commercial mortgage-backed securities transactions, banks, insurance companies and other financial institutions. A significant source of funding for Berkadia’s operations is through the issuance of commercial paper. Repayment of the commercial paper is supported by a surety policy issued by a Berkshire insurance subsidiary. Leucadia has agreed to indemnify us for one-half of any losses incurred under the policy. Berkadia’s maximum outstanding balance of commercial paper borrowings is currently limited to $1.5 billion. On September 30, 2016, the aggregate amount of Berkadia commercial paper outstanding was $1.47 billion.

In the third quarter of 2016, our wholly-owned subsidiary, National Indemnity Company entered into a definitive agreement to acquire Medical Liability Mutual Insurance Company (“MLMIC”), a writer of medical professional liability insurance domiciled in New York. MLMIC’s assets and policyholders’ surplus determined under statutory accounting principles as of June 30, 2016 were approximately $5.5 billion and $1.9 billion, respectively. The acquisition price will be an amount equal to the sum of: (i) the tangible book value of MLMIC at the closing date (determined under U.S. GAAP); plus (ii) $100 million. The acquisition will involve the conversion of MLMIC from a mutual company to a stock company. The closing of the transaction is subject to various regulatory approvals, customary closing conditions and the approval of the MLMIC policyholders eligible to vote on the proposed demutualization and sale. The transaction is currently expected to be completed in late 2017.

New accounting pronouncements (Policies)

Accounting Changes and Error Corrections [Abstract]

New accounting pronouncements

In May 2014, the FASB issued ASU 2014-09 “Revenue from Contracts with Customers.” ASU 2014-09 applies to contracts with customers, excluding, most notably, insurance and leasing contracts. ASU 2014-09 prescribes a framework in accounting for revenues from contracts within its scope, including (a) identifying the contract, (b) identifying the performance obligations under the contract, (c) determining the transaction price, (d) allocating the transaction price to the identified performance obligations and (e) recognizing revenues as the identified performance obligations are satisfied. ASU 2014-09 also prescribes additional financial statement presentations and disclosures. We currently expect to adopt ASU 2014-09 as of January 1, 2018, under the modified retrospective method where the cumulative effect is recognized at the date of initial application. Our evaluation of ASU 2014-09 is ongoing and not complete. The FASB has issued and may issue in the future, interpretative guidance, which may cause our evaluation to change. While we anticipate some changes to revenue recognition for certain customer contracts, we do not currently believe ASU 2014-09 will have a material effect on our Consolidated Financial Statements.

In May 2015, the FASB issued ASU 2015-09 “Financial Services—Insurance—Disclosures about Short-Duration Contracts,” which requires additional disclosures in annual and interim reporting periods by insurance entities regarding liabilities for unpaid claims and claim adjustment expenses, and changes in assumptions or methodologies for calculating such liabilities. ASU 2015-09 is effective for annual periods beginning after December 15, 2015 and interim periods beginning after December 15, 2016. We continue to evaluate the effect adopting this standard will have on the disclosures in our Consolidated Financial Statements.

In January 2016, the FASB issued ASU 2016-01 “Financial Instruments—Recognition and Measurement of Financial Assets and Financial Liabilities.” ASU 2016-01 generally requires that equity investments (excluding equity method investments) be measured at fair value with changes in fair value recognized in net income. Under existing GAAP, changes in fair value of available-for-sale equity investments are recorded in other comprehensive income. Given the current magnitude of our equity investments, the adoption of ASU 2016-01 will likely have a significant impact on the periodic net earnings reported in our Consolidated Statement of Earnings, although it will likely not significantly impact our comprehensive income or shareholders’ equity. ASU 2016-01 is effective for annual and interim periods beginning after December 15, 2017, with the cumulative effect of the adoption made to the balance sheet as of the date of adoption. Thus, the adoption will result in a reclassification of the related accumulated unrealized appreciation currently included in accumulated other comprehensive income to retained earnings, with no impact on Berkshire shareholders’ equity.

In February 2016, the FASB issued ASU 2016-02 “Leases.” ASU 2016-02 requires a lessee to recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term, along with additional qualitative and quantitative disclosures. ASU 2016-02 is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the effect this standard will have on our Consolidated Financial Statements.

In June 2016, the FASB issued ASU 2016-13 “Financial Instruments—Credit Losses,” which provides for the recognition and measurement at the reporting date of all expected credit losses for financial assets held at amortized cost and available-for-sale debt securities. Currently credit losses are recognized and measured when such losses become probable based on the prevailing facts and circumstances. ASU 2016-13 is effective for reporting periods beginning after December 15, 2019. We are currently evaluating the effect this standard will have on our Consolidated Financial Statements.
