NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2012

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”) that included 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. Certain immaterial amounts in 2011 have been reclassified to conform to the current year presentation. Financial information in this 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 relatively 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 value of derivative assets/liabilities associated with derivative contracts that are not accounted for as hedging instruments can cause significant variations in periodic net earnings.

Note 2. New accounting pronouncements

As of January 1, 2012, we adopted FASB Accounting Standards Update (“ASU”) 2010-26, “Accounting for Costs Associated with Acquiring or Renewing Insurance Contracts.” ASU 2010-26 specifies that only direct incremental costs associated with successful efforts in acquiring or renewing of insurance contracts should be capitalized and amortized over the policy term. All other costs are required to be expensed as incurred. Capitalized costs include certain advertising costs if the primary purpose of the advertising is to elicit sales to customers who could be shown to have responded directly to the advertising and the probable future revenues generated from the advertising are in excess of expected future costs to be incurred in realizing those revenues. Berkshire is adopting ASU 2010-26 on a prospective basis. The impact of the adoption of this new standard primarily relates to certain advertising costs of GEICO, which were capitalized prior to the adoption of ASU 2010-26, but are no longer eligible to be capitalized. The adoption of this new standard did not have a material effect on our Consolidated Financial Statements.

As of January 1, 2012, we also adopted ASU 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs.” As a result of adopting ASU 2011-04, we have expanded our fair value disclosures.

In December 2011, the FASB issued ASU 2011-11 “Disclosures about Offsetting Assets and Liabilities.” ASU 2011-11 enhances disclosures surrounding offsetting (netting) assets and liabilities. The standard applies to financial instruments and derivatives and requires companies to disclose both gross and net information about instruments and transactions eligible for offset in financial statements and instruments and transactions subject to a master netting arrangement. ASU 2011-11 is effective retrospectively for Berkshire beginning January 1, 2013. 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 purchase businesses with consistent earning power, good returns on equity and able and honest management at sensible prices.

On September 16, 2011, Berkshire completed the acquisition of The Lubrizol Corporation (“Lubrizol”). The acquisition was pursuant to a merger agreement, whereby Berkshire agreed to acquire all of the outstanding shares of Lubrizol common stock for cash of $135 per share (approximately $8.7 billion in the aggregate). Lubrizol, based in Cleveland, Ohio, is an innovative specialty chemical company that produces and supplies technologies to customers in the global transportation, industrial and consumer markets. These technologies include additives for engine oils, other transportation-related fluids and industrial lubricants, as well as additives for gasoline and diesel fuel. In addition, Lubrizol makes ingredients and additives for personal care products and pharmaceuticals; specialty materials, including plastics; and performance coatings. Lubrizol’s industry-leading technologies in additives, ingredients and compounds enhance the quality, performance and value of customers’ products, while reducing their environmental impact. Lubrizol’s financial results were included in our Consolidated Financial Statements beginning as of September 16, 2011.

Notes To Consolidated Financial Statements (Continued)

Note 3. Significant business acquisitions (Continued)

We have owned a controlling interest in Marmon Holdings, Inc. (“Marmon”) since 2008. In the first quarter of 2011, we increased our ownership in Marmon to 80.2% as a result of acquiring 16.6% of Marmon’s outstanding common stock for approximately $1.5 billion. We will acquire substantially all of the remaining noncontrolling interests of Marmon in 2013 and/or 2014 for an amount that will be based on its future operating results. In June 2011, we acquired all of the then outstanding noncontrolling interests in Wesco Financial Corporation for aggregate consideration of $543 million consisting of cash of approximately $298 million and 3,253,472 shares of Berkshire Class B common stock.

Investments in foreign government securities include securities issued by national and provincial government entities as well as instruments that are unconditionally guaranteed by such entities. As of March 31, 2012, approximately 95% of foreign government holdings were rated AA or higher by at least one of the major rating agencies. Investments in obligations issued or guaranteed by Germany, the United Kingdom, Canada, Australia and the Netherlands represent approximately 80% of the investments in foreign government obligations. Unrealized losses on fixed maturity investments in a continuous unrealized loss position for more than twelve consecutive months were $15 million as of March 31, 2012 and $20 million as of December 31, 2011.

The amortized cost and estimated fair value of securities with fixed maturities at March 31, 2012 are summarized below by contractual maturity dates.

As of March 31, 2012 and December 31, 2011, there were no equity securities in a continuous unrealized loss position for more than twelve consecutive months. As of March 31, 2012 and December 31, 2011, we concluded that the unrealized losses 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 each of these issuers was favorable; (c) our opinion that the relative price declines were not significant; and (d) our belief that it was reasonably possible that market prices will increase to and exceed our cost in a relatively short period of time.

In 2008, we acquired 50,000 shares of 10% Cumulative Perpetual Preferred Stock of GS (“GS Preferred”) and warrants to purchase 43,478,260 shares of common stock of GS (“GS Warrants”) for a combined cost of $5 billion. The GS Preferred was redeemable at any time by GS at a price of $110,000 per share ($5.5 billion in aggregate). On April 18, 2011, GS fully redeemed our GS Preferred investment. The GS Warrants remain outstanding and expire on October 1, 2013. The GS Warrants are exercisable for an aggregate cost of $5 billion ($115/share).

In 2008, we acquired 30,000 shares of 10% Cumulative Perpetual Preferred Stock of GE (“GE Preferred”) and warrants to purchase 134,831,460 shares of common stock of GE (“GE Warrants”) for a combined cost of $3 billion. The GE Preferred was redeemable by GE beginning in October 2011 at a price of $110,000 per share ($3.3 billion in aggregate). On October 17, 2011, GE fully redeemed our GE Preferred investment. The GE Warrants remain outstanding and expire on October 16, 2013. The GE Warrants are exercisable for an aggregate cost of $3 billion ($22.25/share).

In 2008, we acquired $4.4 billion par amount of 11.45% Wrigley subordinated notes due in 2018 and $2.1 billion of 5% Wrigley preferred stock. In 2009, we also acquired $1.0 billion par amount of Wrigley senior notes due in 2013 and 2014. We currently own $800 million and an unconsolidated joint venture in which we hold a 50% economic interest owns $200 million of the Wrigley senior notes. The Wrigley subordinated and senior notes are classified as held-to-maturity and we carry these investments at cost, adjusted for foreign currency exchange rate changes that apply to certain of the senior notes. The Wrigley preferred stock is classified as available-for-sale and recorded in our financial statements at fair value.

In 2009, we acquired 3,000,000 shares of Series A Cumulative Convertible Perpetual Preferred Stock of Dow (“Dow Preferred”) for a cost of $3 billion. Under certain conditions, we can convert each share of the Dow Preferred into 24.201 shares of Dow common stock (equivalent to a conversion price of $41.32 per share). Beginning in April 2014, if Dow’s common stock price exceeds $53.72 per share for any 20 trading days in a consecutive 30-day window, Dow, at its option, at any time, in whole or in part, may convert the Dow Preferred into Dow common stock at the then applicable conversion rate. The Dow Preferred is entitled to dividends at a rate of 8.5% per annum.

On September 1, 2011, we acquired 50,000 shares of 6% Cumulative Perpetual Preferred Stock of BAC (“BAC Preferred”) and warrants to purchase 700,000,000 shares of common stock of BAC (“BAC Warrants”) for a combined cost of $5 billion. The BAC Preferred is redeemable at any time by BAC at a price of $105,000 per share ($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).

Other-than-temporary impairment (“OTTI”) losses were as follows (in millions).

	First Quarter
	2012		2011
Equity securities	$	—	$	506
Fixed maturity securities		337		—
	$	337	$	506

We reflect investments in equity and fixed maturity securities classified as available-for-sale at fair value with the difference between fair value and cost included in other comprehensive income. OTTI 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 corresponding credit to other comprehensive income and therefore have no net effect on shareholders’ equity.

In the first quarter of 2012, we recorded OTTI losses of $337 million on certain fixed maturity investments where we concluded that we were unlikely to receive all of the remaining contractual interest and principal amounts when due. All of these losses were attributable to a single issuer. In the first quarter of 2011, we recorded OTTI losses of $506 million related to certain of our investments in equity securities. The OTTI losses included $337 million with respect to 103.6 million shares of our investment in Wells Fargo & Company (“Wells Fargo”) common stock. These shares had an aggregate original cost of $3,621 million. At that time, we also held an additional 255.4 million shares of Wells Fargo which were acquired at an aggregate cost of $4,394 million and had unrealized gains of $3,704 million as of March 31, 2011. Due to the length of time that certain of our Wells Fargo shares were in a continuous unrealized loss position and because we account for gains and losses on a specific identification basis, accounting regulations required us to record the unrealized losses in earnings. However, the unrealized gains were not reflected in earnings but were instead recorded directly in shareholders’ equity as a component of accumulated other comprehensive income.

Allowances for uncollectible loans		(386	)		(389	)
	$	13,799		$	13,934

Allowances for uncollectible loans primarily relate to consumer installment loans. Provisions for consumer loan losses for the first quarter were $80 million in 2012 and $82 million in 2011. Loan charge-offs, net of recoveries, for the first quarter were $83 million in 2012 and $81 million in 2011. Consumer loan amounts are net of unamortized acquisition discounts of $512 million at March 31, 2012 and $500 million at December 31, 2011. At March 31, 2012, approximately 96% of consumer installment loan balances were evaluated collectively for impairment whereas about 85% of commercial loan balances were evaluated individually for impairment. As a part of the evaluation process, credit quality indicators are reviewed and loans are designated as performing or non-performing. At March 31, 2012, approximately 98% of consumer installment and commercial loan balances were determined to be performing and approximately 94% of those balances were current as to payment status.

Note 12. Derivative contracts

As of March 31, 2012, derivative contracts are used primarily by our finance and financial products and energy businesses. Substantially all of the derivative contracts of our finance and financial products businesses are not designated as hedges for financial reporting purposes. We entered into these contracts with the expectation that the premiums received would exceed the amounts ultimately paid to counterparties. Changes in the fair values of such contracts are reported in earnings as derivative gains/losses. A summary of derivative contracts of our finance and financial products businesses follows (in millions).

(2)	Represents the maximum undiscounted future value of losses payable under the contracts. The number of losses required to exhaust contract limits under substantially all of the contracts is dependent on the loss recovery rate related to the specific obligor at the time of a default.
(3)	Included in other assets of finance and financial products businesses.

Derivative gains/losses of our finance and financial products businesses included in our Consolidated Statements of Earnings for the first quarter of 2012 and 2011 were as follows (in millions).

	First Quarter
	2012			2011
Equity index put options	$	689		$	223
Credit default obligations		340			70
Other		(27	)		(22	)
	$	1,002		$	271

The equity index put option contracts are European style options written on four major equity indexes. Future payments, if any, under these contracts will be required if the underlying index value is below the strike price at the contract expiration dates, which occur between June 2018 and January 2026. We received the premiums on these contracts in full at the contract inception dates and therefore have no counterparty credit risk. We entered into no new contracts in 2011 or 2012.

At March 31, 2012, the aggregate intrinsic value (the undiscounted liability assuming the contracts are settled on their future expiration dates based on the March 31, 2012 index values and foreign currency exchange rates) was approximately $4.5 billion. However, these contracts may not be unilaterally terminated or fully settled before the expiration dates and therefore the ultimate amount of cash basis gains or losses on these contracts will not be determined for many years. The remaining weighted average life of all contracts was approximately 8.75 years at March 31, 2012.

Our credit default contracts pertain to various indexes of non-investment grade (or “high yield”) corporate issuers, as well as investment grade state/municipal and individual corporate debt issuers. These contracts cover the loss in value of specified debt obligations of the issuers arising from default events, which are usually from their failure to make payments or bankruptcy. Loss amounts are subject to aggregate contract limits. We entered into no new contracts in 2011 or 2012.

Notes To Consolidated Financial Statements (Continued)

Note 12. Derivative contracts (Continued)

The high yield index contracts are comprised of specified North American corporate issuers (usually 100 in number at inception) whose obligations are rated below investment grade. High yield contracts in-force at March 31, 2012 expire in 2012 and 2013. State and municipality contracts are comprised of over 500 state and municipality issuers and had a remaining weighted average contract life at March 31, 2012 of approximately 9.0 years. Loss payments, if any, related to approximately 50% of the notional value of the state and municipality contracts cannot be settled before the maturity dates of the underlying municipality obligation, which range from 2019 to 2054.

Premiums on the high yield index and state/municipality contracts were received in full at the inception dates of the contracts and, as a result, we have no counterparty credit risk. Our payment obligations under certain of these contracts are on a first loss basis. Losses under other contracts are subject to aggregate deductibles that must be satisfied before we have any payment obligations.

Individual corporate credit default contracts primarily relate to issuers of investment grade obligations. In most instances, premiums are due from counterparties on a quarterly basis over the terms of the contracts. As of March 31, 2012, all of the remaining contracts in-force will expire in 2013.

With limited exceptions, our equity index put option and credit default contracts contain no collateral posting requirements with respect to changes in either the fair value or intrinsic value of the contracts and/or a downgrade of Berkshire’s credit ratings. As of March 31, 2012, our collateral posting requirement under contracts with collateral provisions was $45 million compared to $238 million at December 31, 2011. 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, additional collateral of up to $1.1 billion could be required to be posted.

Our regulated utility subsidiaries are exposed to variations in the market prices in the purchases and sales of natural gas and electricity and in the purchases of fuel. Derivative instruments, including forward purchases and sales, futures, swaps and options, are used to manage these price risks. Unrealized gains and losses under the contracts of our regulated utilities that are probable of recovery through rates are recorded as regulatory assets or liabilities. Unrealized gains or losses on contracts accounted for as cash flow or fair value hedges are recorded in accumulated other comprehensive income or in net earnings, as appropriate. Derivative contract assets included in other assets of railroad, utilities and energy businesses were $61 million and $71 million as of March 31, 2012 and December 31, 2011, respectively. Derivative contract liabilities included in accounts payable, accruals and other liabilities of railroad, utilities and energy businesses were $472 million as of March 31, 2012 and $336 million as of December 31, 2011.

MidAmerican subsidiary debt represents amounts issued pursuant to separate financing agreements. All or substantially all of the assets of certain MidAmerican subsidiaries are or may be pledged or encumbered to support or otherwise secure the 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 unsecured. In the first quarter of 2012, MidAmerican subsidiaries issued $1.6 billion of debt with interest rates from 2.95% to 5.75% and maturities ranging from 2015 to 2042. In the third and fourth quarters of 2012, MidAmerican and subsidiary debt of approximately $1.0 billion will mature. In March 2012, BNSF issued $1.25 billion in debentures comprised of $625 million of 3.05% debentures due in March 2022 and $625 million of 4.40% debentures due in March 2042. As of March 31, 2012, BNSF and MidAmerican and their subsidiaries were in compliance with all applicable covenants. Berkshire does not guarantee any debt or other borrowings of BNSF, MidAmerican or their subsidiaries.

Note 15. Common stock

Changes in Berkshire’s issued and outstanding common stock during the first quarter of 2012 are shown in the table below.

	Class A, $5 Par Value (1,650,000 shares authorized)									Class B, $0.0033 Par Value (3,225,000,000 shares authorized)
	Issued			Treasury			Outstanding			Issued		Treasury			Outstanding
Balance at December 31, 2011		938,342			(98	)		938,244			1,069,645,361		(801,985	)		1,068,843,376

Balance at March 31, 2012		932,712			(98	)		932,614			1,078,675,232		(801,985	)		1,077,873,247

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 1,651,196 shares outstanding as of March 31, 2012 and 1,650,806 shares outstanding as of December 31, 2011. In addition to our common stock, 1,000,000 shares of preferred stock are authorized, but none of which are issued and outstanding.

In September 2011, our Board of Directors approved a common stock repurchase program whereby it authorized Berkshire to repurchase its Class A and Class B shares at prices no higher than a 10% premium over the book value of the shares. Berkshire may repurchase shares in the open market or through privately negotiated transactions, at management’s discretion. Berkshire’s Board of Directors’ 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 equivalent holdings 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.

Note 16. Fair value measurements (Continued)

Fair values for 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 estimates presented herein are not necessarily indicative of the amounts that could be realized in an actual current market exchange. The use of different 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.

Level 1 – Inputs represent unadjusted quoted prices for identical assets or liabilities exchanged in active markets. Substantially all of our investments in equity securities are traded on an exchange in active markets and fair values are based on the closing prices as of the balance sheet date.

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. Fair values of investments in fixed maturity securities and notes payable and other borrowings are primarily based on price evaluations which incorporate market prices for identical instruments in inactive markets and market data available for instruments with similar characteristics. Pricing evaluations generally reflect discounted expected future cash flows, which incorporate yield curves for instruments with similar characteristics, such as credit rating, estimated duration 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 or related observable inputs that can be corroborated at the measurement date. Unobservable inputs require management to make certain projections and assumptions about the information that would be used by market participants in pricing assets or liabilities. Measurements of non-exchange traded derivative contracts and certain other investments carried at fair value are based primarily on valuation models, discounted cash flow models or other valuation techniques that are believed to be used by market participants.

Financial instruments measured at fair value on a recurring basis are summarized, according to the hierarchy previously described, as follows (in millions).

Note 16. Fair value measurements (Continued)

As of March 31, 2011, we transferred our investment in GS Preferred to Level 2 given the then pending redemption of that investment which occurred on April 18, 2011. There were no transfers into Level 3 for the first quarter of 2012 or 2011. Gains and losses included in net earnings are included as components of investment gains/losses, derivative gains/losses and other revenues, as appropriate and are related to changes in valuations of derivative contracts and disposal or settlement transactions. Gains and losses included in other comprehensive income are included as components of net change in unrealized appreciation of investments and reclassification of investment appreciation in earnings, as appropriate in the Consolidated Statements of Comprehensive Income.

Quantitative information as of March 31, 2012, 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 Input	Weighted Average
Other investments:
Preferred stocks	$	11,307	Discounted cash flow	Expected duration	10 years
				Discount for transferability restrictions and subordination	97 Bps

Common stock warrants		2,851	Warrant pricing model	Discount for transferability and hedging restrictions	18%

Net derivative liabilities:
Equity index put options		7,810	Option pricing model	Volatility	22%

Credit default-states/municipalities		1,025	Discounted cash flow	Credit default spreads	120 Bps

For certain credit default and other derivative contracts where we could not corroborate that the fair values or the inputs were observable in the market, fair values were based on non-binding price indications obtained from third party sources. Management reviewed these values relative to the terms of the contracts and concluded they were reasonable. We did not adjust these prices and therefore, they have been excluded from the preceding table.

Our other investments consist of a few relatively large private placement transactions and include perpetual preferred stock and common stock warrants. These investments are subject to contractual restrictions on transferability and/or provisions that prevent us economically from 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 have the right to redeem these investments. We also made estimates regarding the impact of subordination, as the preferred stock has a lower priority in liquidation than the investment grade debt instruments of the issuers, which affected the discount rates. 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. We have applied discounts with respect to the contractual restrictions. Increases or decreases to these inputs would result in decreases or increases to the fair values.

Our equity index put option and credit default contracts are not exchange traded and certain contract terms are not standard in derivatives markets. For example, we are not required to post collateral under most of our contracts and many contracts have long durations, and therefore are illiquid. 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 current index price, contract duration, dividend and interest rate inputs (which include a Berkshire performance input) which are observable. However, the valuation of long-duration options is inherently subjective, given the lack of observable transactions and prices, and acceptable values may be subject to wide ranges. Expected volatility inputs represent our expectations after considering the remaining duration of each contract and 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.

Our state and municipality credit default contract values reflect credit default spreads, contract durations, interest rates, bond prices and other inputs believed to be used by market participants in estimating fair value. We utilize discounted cash flow valuation models, which incorporate the aforementioned inputs as well as our own estimates of credit default spreads for states and municipalities where there is no observable input. Increases or decreases to the credit default spreads will produce increases or decreases in the fair values.

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 efforts, including, but not limited to, communicating the appropriate “tone at the top” messages to its employees and associates, monitoring governance efforts at the operating businesses, and participating in the resolution of governance-related issues as needed. The business segment data (Note 17 to the Consolidated Financial Statements) should be read in conjunction with this discussion. We completed the acquisition of The Lubrizol Corporation on September 16, 2011 and its results are included for the first quarter of 2012 as a component of manufacturing, service and retailing businesses in the preceding table.

During the first quarter of 2011, insurance underwriting results of our reinsurance operations included after-tax losses of approximately $1.1 billion from several significant catastrophe events. We incurred no significant losses from catastrophes during the first quarter of 2012.

Investment and derivative gains/losses in the first quarter included after-tax gains from derivative contracts of $650 million in 2012 and $176 million in 2011. Investment and derivative gains/losses in the first quarter also included after-tax other-than-temporary impairment (“OTTI”) losses of $219 million in 2012 and $322 million in 2011. In 2012, the OTTI losses related to fixed maturity investments in a single issuer where we concluded that we are unlikely to receive all contractual cash flows when due. In 2011, the OTTI losses related to certain equity securities. We believe that realized investment gains/losses and OTTI losses are often meaningless in terms of understanding our reported results or evaluating our economic performance. These gains and losses and changes in the equity and credit markets from period to period 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 and casualty 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. General Re and BHRG also reinsure life and health risks.

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 the performance of underwriting operations without any allocation of investment income.

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

Insurance—Underwriting (Continued)

Our periodic underwriting results are affected significantly by changes in estimates for unpaid losses and loss adjustment expenses, including amounts established for occurrences in prior years. The timing and amount of catastrophe losses can produce significant volatility in our periodic underwriting results, particularly with respect to BHRG and General Re. We incurred no significant losses from catastrophes occurring in the first quarter of 2012. In the first quarter of 2011, we recorded aggregate estimated pre-tax losses of approximately $1.7 billion arising from several catastrophe events, including the earthquakes in Japan and New Zealand, as well as a cyclone and floods in Australia. Our periodic underwriting results may also include significant foreign currency transaction gains and losses arising from the changes in the valuations of certain non-U.S. Dollar denominated reinsurance liabilities as a result of foreign currency exchange rate fluctuations.

A key marketing strategy followed by all of our insurance businesses is the maintenance of extraordinary capital strength. Statutory surplus of our insurance businesses was approximately $95 billion at December 31, 2011. 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.

A summary follows of underwriting results from our insurance businesses. Amounts are in millions.

GEICO

Through GEICO, we primarily write 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.

	First Quarter
	2012				2011
	Amount		%		Amount		%
Premiums earned	$	4,016		100.0	$	3,675		100.0
Losses and loss adjustment expenses		2,933		73.0		2,653		72.2
Underwriting expenses		959		23.9		685		18.6
Total losses and expenses		3,892		96.9		3,338		90.8
Pre-tax underwriting gain	$	124			$	337

Premiums earned in the first quarter of 2012 increased $341 million (9.3%) to $4,016 million. The growth in premiums earned for voluntary auto was 9.3%, as policies-in-force increased 6.5% during the past year. The increase in policies-in-force reflects a decrease of 2.7% in voluntary auto new business sales compared with the strong new business sales in the first quarter of 2011. Voluntary auto policies-in-force at March 31, 2012 were approximately 287,000 greater than at December 31, 2011. In recent years, the growth in voluntary auto policies-in-force has been the greatest during the first quarter.

Losses and loss adjustment expenses incurred in the first quarter of 2012 were $2,933 million, an increase of $280 million (10.6%) versus the first quarter of 2011. The loss ratio (the ratio of losses and loss adjustment expenses incurred to premiums earned) was 73.0% in the first quarter of 2012 compared to 72.2% in 2011. The increase in the loss ratio in the first quarter of 2012 reflected higher average injury and physical damage severities estimates. In the first quarter of 2012, bodily injury severities estimates generally increased in the one to two percent range over 2011, while physical damage severities increased in the six to nine percent range.

GEICO (Continued)

Underwriting expenses in the first quarter of 2012 were $959 million, an increase of $274 million (40.0%) over 2011. The increase was primarily the result of a change in U.S. GAAP accounting standards regarding deferred policy acquisition costs (“DPAC”), which represent certain underwriting costs that are eligible to be capitalized and expensed over the policy period as the related premiums are earned. As a result of adopting the new accounting standard, beginning in 2012, GEICO ceased deferring a large portion of its direct advertising cost. Through prospective adoption of the new accounting standard, DPAC as of December 31, 2011 will be amortized to expense over the remainder of the related policy periods. Acquisition costs related to policies written and renewed after December 31, 2011 will be deferred at lower levels than in the past. The new accounting standard for DPAC does not impact the cash basis underwriting costs or our assessment of GEICO’s underwriting performance. However, the new standard accelerates the timing of when underwriting costs are recognized in earnings.

We estimate that GEICO’s underwriting expenses for the first quarter of 2012 would have been about $250 million less had we computed DPAC under the prior standard and that its expense ratio in 2012 would have been less than 2011. We anticipate that substantially all the effect of transitioning to this new standard will be completed by the end of the third quarter of 2012. Thereafter, we expect that the amount of GEICO underwriting expenses reported in earnings will decline to near the historical levels as measured by the ratio of underwriting expenses to premiums earned.

General Re

Through General Re, we conduct a reinsurance business offering property and casualty and life and health coverages to clients worldwide. We write property and casualty reinsurance in North America on a direct basis through General Reinsurance Corporation and internationally through Germany-based General Reinsurance AG and other wholly-owned affiliates. Property and casualty reinsurance is also written through brokers with respect to Faraday in London. Life and health reinsurance is written in North America through General Re Life Corporation and internationally through 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.

	First Quarter
	Premiums earned				Pre-tax underwriting gain (loss)
	2012		2011		2012		2011
Property/casualty	$	735	$	715	$	46	$	(324	)
Life/health		736		722		35		(2	)
	$	1,471	$	1,437	$	81	$	(326	)

Property/casualty

Property/casualty premiums earned in the first quarter of 2012 were $735 million, an increase of $20 million (2.8%) compared to 2011. Excluding the effects of foreign currency exchange rate changes, premiums earned in the first quarter of 2012 increased $31 million (4.3%), which was primarily due to increases in international treaty business. Price competition in most property and casualty lines persists. Our underwriters continue to exercise discipline by not accepting offers to write business where prices are deemed inadequate. We remain prepared to increase premium volumes should market conditions improve.

Underwriting results in the first quarter of 2012 included underwriting gains of $66 million from property business, offset in part by underwriting losses of $20 million from casualty/workers’ compensation business. The property underwriting gains reflect an absence of significant catastrophe losses as well as underwriting gains from the run-off of prior years’ business. The timing and magnitude of catastrophe and large individual losses has produced and is expected to continue to produce significant volatility in periodic underwriting results. The underwriting losses from casualty/workers’ compensation business included $26 million from loss reserve discount accretion and deferred charge amortization.

Underwriting losses in the first quarter of 2011 consisted of $355 million of losses from property business offset in part by underwriting gains of $31 million from casualty/workers’ compensation businesses. The property results included $491 million of catastrophe losses incurred, which were primarily from the earthquakes in Japan and New Zealand. The underwriting gains of $31 million from casualty/workers’ compensation business reflected overall favorable run-off of prior years’ casualty loss reserves.

Life/health

Premiums earned in the first quarter of 2012 were $736 million, an increase of $14 million (1.9%) over 2011. Adjusting for the effects of foreign currency exchange rate changes, premiums earned increased 4.1% over the first quarter of 2011. The increase in premiums earned was primarily due to increased non-U.S. life business. The life/health operations produced an underwriting gain of $35 million in 2012 as compared to an underwriting loss of $2 million in 2011. The first quarter of 2012 underwriting gain was primarily due to lower than expected mortality. The loss in the first quarter of 2011 included $40 million of incurred losses related to the earthquakes in Japan and New Zealand and also reflected increases in frequency and severity of life and health claims in the U.S.

Berkshire Hathaway Reinsurance Group (“BHRG”)

Through BHRG, we underwrite excess-of-loss reinsurance and quota-share coverages on property and casualty risks for insurers and reinsurers worldwide. BHRG’s business includes catastrophe excess-of-loss reinsurance and excess primary and facultative reinsurance for large or otherwise unusual property risks referred to as individual risk. BHRG also writes retroactive reinsurance, which provides indemnification of losses and loss adjustment expenses with respect to past loss events. Other multi-line business refers to other property and casualty business written on both a quota-share and excess basis and includes a quota-share contract with Swiss Reinsurance Company Ltd. (“Swiss Re”) covering a 20% share of substantially all of Swiss Re’s property/casualty contracts incepting between January 1, 2008 and December 31, 2012. We currently do not anticipate that the Swiss Re quota-share contract will be renewed or extended. BHRG’s underwriting activities also include life reinsurance and annuity business. BHRG’s underwriting results are summarized in the table below. Amounts are in millions.

	First Quarter
	Premiums earned				Pre-tax underwriting gain (loss)
	2012		2011		2012			2011
Catastrophe and individual risk	$	134	$	189	$	82		$	(273	)
Retroactive reinsurance		298		143		(73	)		(155	)
Other multi-line property/casualty		1,125		1,133		(130	)		(910	)
Life and annuity		514		479		(70	)		(5	)
	$	2,071	$	1,944	$	(191	)	$	(1,343	)

Premiums earned in the first quarter of 2012 from catastrophe and individual risk contracts declined $55 million (29%) versus the first quarter of 2011. The level of business written in a given period will vary significantly due to changes in market conditions and management’s assessment of the adequacy of premium rates. We have generally constrained the volume of business written in recent years as premium rates have not been attractive enough to warrant increasing volume. However, we have the capacity and willingness to write substantially more business when appropriate pricing can be obtained.

Catastrophe and individual risk underwriting results for the first quarter of 2012 reflected no significant losses from catastrophe events, while results for the first quarter of 2011 included estimated losses of $454 million from the earthquakes in Japan and New Zealand. Catastrophe and individual risk contracts may provide exceptionally large limits of indemnification and cover catastrophe risks (such as hurricanes, earthquakes or other natural disasters) or other property and liability risks. The timing and magnitude of losses produces extraordinary volatility in periodic underwriting results of this business.

Retroactive reinsurance policies generally provide very large, but limited, indemnification of losses and loss adjustment expenses with respect to past loss events that are generally expected to be paid over long periods of time. Underwriting results attributable to retroactive reinsurance include the recurring periodic amortization of deferred charges that are established with respect to these contracts. At the inception of a contract, deferred charges represent the difference between the premium received and the estimated ultimate losses payable. Deferred charges are subsequently amortized over the estimated claims payment period using the interest method, which reflects estimates of the timing and amount of loss payments. The original estimates of the timing and amount of loss payments are analyzed against actual experience and as necessary are 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 as a component of losses and loss adjustment expenses.

Insurance —Underwriting (Continued)

Berkshire Hathaway Reinsurance Group (“BHRG”) (Continued)

The underwriting losses from retroactive policies for the first quarter of 2012 and 2011 primarily represent the amortization of deferred charges. At March 31, 2012 and December 31, 2011, unamortized deferred charges for all of BHRG’s retroactive contracts were approximately $3.9 billion and $4.0 billion, respectively. Gross unpaid losses from retroactive reinsurance contracts were approximately $18.6 billion at March 31, 2012 compared to approximately $18.8 billion as of December 31, 2011.

Premiums earned in the first quarters of 2012 and 2011 from other multi-line property and casualty business included $746 million and $785 million, respectively, from the Swiss Re quota-share contract. Other multi-line property and casualty underwriting losses in the first quarters of 2012 and 2011 were $130 million and $910 million, respectively. Underwriting results can be significantly impacted by the timing and magnitude of catastrophe losses (arising primarily from the Swiss Re quota-share contract) and fluctuations in foreign currency exchange rates. While there were no significant catastrophe loss events in 2012, we increased liability estimates for prior years’ losses by approximately $53 million. Underwriting results in the first quarter of 2011 included estimated catastrophe losses of $701 million from the Swiss Re quota-share contract. Other multi-line property and casualty underwriting results also included losses of $135 million in the first quarter of 2012 and $173 million in the first quarter of 2011 arising from the conversion of certain reinsurance liabilities denominated in foreign currencies into U.S. Dollars.

Life and annuity premiums earned in the first quarters of 2012 and 2011 primarily derive from life reinsurance contracts, including a contract with Swiss Re Life & Health America Inc. covering yearly renewable term risks. Underwriting losses of the life and annuity business were $70 million for the first quarter of 2012 and $5 million for the first quarter of 2011. For the first quarter, the life reinsurance business produced an underwriting loss of $21 million in 2012 compared to an underwriting gain of $16 million in 2011. The underwriting results of the life and annuity business also include underwriting losses related to a portfolio of annuity contracts, most of which were written several years ago. For the first quarter, the annuity business generated underwriting losses of $49 million in 2012 and $21 million in 2011. The increase in annuity underwriting losses in 2012 was primarily attributable to unfavorable foreign currency exchange rate changes and lower mortality gains. At March 31, 2012 and December 31, 2011, annuity liabilities were approximately $2.15 billion and $2.07 billion, respectively.

Berkshire Hathaway Primary Group

Our primary insurance group consists of a wide variety of independently managed insurance businesses that principally write liability coverages for commercial accounts. These businesses include: Medical Protective Corporation and Princeton Insurance Company (acquired as of December 30, 2011), providers of professional liability insurance to physicians, dentists and other healthcare providers; National Indemnity Company’s primary group, 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 internally as “Berkshire Hathaway Homestate Companies,” providers of commercial multi-line insurance, including workers’ compensation; Central States Indemnity Company, a provider of credit and disability insurance to individuals nationwide through financial institutions; Applied Underwriters, a provider of integrated workers’ compensation solutions; and BoatU.S., a writer of insurance for owners of boats and small watercraft.

Premiums earned in the first quarter by our various primary insurers were $507 million in 2012 and $426 million in 2011. The increase in premiums earned in 2012 was primarily due to increased volume from the Berkshire Hathaway Homestate Companies and premiums from Princeton Insurance Company. Premium volume of our primary insurers, in general, continues to be constrained by market conditions. We have the capacity and desire to write substantially more volume if market conditions improve. For the first quarter, our primary insurers produced underwriting gains of $71 million in 2012 and $56 million in 2011. Underwriting gains as a percentage of premiums earned for the first quarter of 2012 was 14%, which was relatively unchanged from 2011.

Insurance—Investment Income (Continued)

Investment income consists of interest and dividends earned on cash and investments of our insurance businesses. Pre-tax investment income in the first quarter of 2012 was $1,052 million, a decline of $209 million (17%) from 2011. The decline in investment income in 2012 was attributable to the redemptions in 2011 of our investments in Goldman Sachs 10% Preferred Stock (approximately 87% of the $5 billion aggregate investment was held by insurance subsidiaries) and in General Electric 10% Preferred Stock ($3 billion). Dividends earned by insurance subsidiaries from these investments were $278 million in the first quarter of 2011. Our investment income earned over the remainder of 2012 will likely be negatively affected by these redemptions, given the comparatively lower yields currently available from new investment opportunities. In 2012, investment income was favorably impacted by increased dividend rates with respect to several of our common stock holdings. Investment income for the first quarter of 2012 also included dividends earned from our investment in Bank of America 6% Preferred Stock; of which our insurance subsidiaries hold $4 billion in aggregate liquidation amount.

Invested assets derive from shareholder capital and reinvested earnings as well as 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 premiums and reinsurance receivables, deferred charges assumed under retroactive reinsurance contracts and deferred policy acquisition costs. Float approximated $71.7 billion at March 31, 2012 and $70.6 billion at December 31, 2011. In the first quarter of 2012, the cost of float, as represented by the ratio of our underwriting gain or loss to average float, was negative as our insurance group generated a net underwriting gain. For the first quarter of 2011, the cost of float was approximately 2%, as our insurance businesses, in the aggregate, generated a net underwriting loss.

A summary of cash and investments held in our insurance businesses follows. Other investments include our investments in Wrigley, Dow Chemical and Bank of America as well as warrants to acquire common shares of Goldman Sachs, General Electric and Bank of America (See Note 6 to the Consolidated Financial Statements).

Railroad (“BNSF”)

We acquired control of Burlington Northern Santa Fe Corporation, (“BNSF”), on February 12, 2010. BNSF operates one of the largest railroad systems in North America with approximately 32,000 route miles of track in 28 states and two Canadian provinces. BNSF’s major business groups are classified by product shipped and include consumer products, coal, industrial products and agricultural products. Earnings of BNSF are summarized below (in millions).

Net earnings	$	701	$	607

Revenues for the first quarter of 2012 were approximately $5.0 billion, an increase of $469 million (10%) over 2011. Revenues from each of the four business groups increased as compared to 2011, reflecting a 7% increase in average revenues per car/unit, as well as a 3% increase in the volume of cars/units handled. Revenues in each period include fuel surcharges to customers under programs intended to recover incremental fuel costs when fuel prices exceed threshold fuel prices. Fuel surcharges increased by 16% as compared to 2011 which is reflected in average revenue per car/unit.

The 3% increase in volume is comprised of increases of 6% and 11% in cars/units handled in the consumer products and industrial products groups, respectively, combined with 4% and 5% decreases in volume for coal products and agricultural products, respectively. The consumer products volume increase was attributable primarily to higher domestic intermodal and automotive volume. The decline in coal unit volume was attributable to decreased coal demand as a result of low natural gas prices, a mild winter and rising utility stockpiles. Industrial products volume increased primarily as a result of increased shipments of petroleum products, as well as increased steel and sand shipments. Agricultural product volume decreased due to a decline in wheat shipments for export partially offset by higher U.S. corn shipments.

Operating expenses in the first quarter of 2012 were approximately $3.7 billion, representing an increase of $307 million (9%) over 2011. Fuel expenses increased $156 million in 2012 primarily due to higher fuel prices and volume increases, partially offset by improved fuel efficiency. Compensation and benefits expenses increased $42 million, reflecting volume-related costs, as well as inflation. Purchased services expenses increased $22 million due primarily to volume-related and locomotive maintenance costs. Materials and other expenses increased $61 million due to an unfavorable arbitration ruling in 2012.

Utilities and Energy (“MidAmerican”)

We hold an 89.8% ownership interest in MidAmerican Energy Holdings Company (“MidAmerican”), which operates an international energy business. MidAmerican’s domestic regulated energy interests are comprised of two regulated utility companies, PacifiCorp and MidAmerican Energy Company (“MEC”). MidAmerican also operates two interstate natural gas pipeline companies. In the United Kingdom, MidAmerican operates two electricity distribution businesses, operating as Northern Powergrid Holdings Company (“Northern Powergrid”). The rates that utility and natural gas pipeline companies charge customers for energy and other services are generally subject to regulatory approval. Rates are based in large part on the costs of business operations, including a return on capital. To the extent these operations are not allowed to include such costs in the approved rates, operating results will be adversely affected. In addition, MidAmerican also operates a diversified portfolio of independent power projects and the second-largest residential real estate brokerage firm in the United States.

PacifiCorp’s first quarter of 2012 revenues were $1,209 million, an increase of $77 million (7%) over the first quarter of 2011. The increase reflected higher retail revenues ($48 million) and wholesale and other revenues ($24 million). The increase in retail revenues included higher regulator approved cost-based prices ($60 million), and was partially offset by lower retail customer load ($12 million) attributable to the impacts of mild weather on residential loads in PacifiCorp's eastern service territory. The increase in wholesale and other revenues was due to higher volumes of $32 million on higher short-term sales from increased thermal generation availability and improved natural gas spark spreads, partially offset by lower average market prices on short-term wholesale sales. Additionally, renewable energy credit revenue increased $16 million.

PacifiCorp’s earnings before corporate interest and income taxes (“EBIT”) in the first quarter of 2012 were $208 million, an increase of $18 million (9%) over the first quarter of 2011. Earnings were favorably impacted by higher revenues and lower interest expense, which were largely offset by higher energy costs ($62 million) and higher depreciation and amortization ($6 million). Energy costs in 2012 increased due to reduced gains from electricity swap settlements ($51 million), higher thermal generation and the impact of energy adjustment mechanisms ($15 million), and were partially offset by lower purchased power volumes.

MEC’s first quarter 2012 revenues of $881 million declined $104 million (11%) and its EBIT of $56 million declined $15 million (21%) from the first quarter of 2011. MEC’s regulated electric revenues and earnings in the first quarter of 2012 were relatively unchanged from 2011. Regulated natural gas revenues decreased $70 million (21%) for the first quarter of 2012 compared to the first quarter of 2011 primarily attributable to lower average per-unit cost of gas sold and an 8% decline in volumes sold as a result of unseasonably warm weather. Nonregulated and other operating revenues decreased $38 million due to lower electricity and natural gas prices and volumes. The decline in EBIT was primarily attributable to lower regulated natural gas volume-related margins and lower non regulated electric margins, partially offset by lower interest expense.

Natural gas pipeline revenues increased $5 million (2%) for the first quarter of 2012 compared to the first quarter of 2011. The revenue increase was primarily due to increased capacity from Kern River ’ s Apex Expansion project, which was placed in service in October of 2011, and from better natural gas price spreads, partially offset by contract expirations. Natural gas pipeline EBIT increased $5 million (3%) for the first quarter of 2012 versus 2011 which was primarily due to the higher revenues, partially offset by higher depreciation associated with the Kern River Apex Expansion project.

Utilities and Energy (“MidAmerican”) (Continued)

Northern Powergrid’s revenues increased $10 million (4%) in the first quarter of 2012 compared to the first quarter of 2011. The increase was primarily due to higher distribution revenues ($18 million), partially offset by the stronger U.S. Dollar ($5 million). Distribution revenues increased due to comparatively higher rates ($31 million), partially offset by comparatively lower recoveries of certain regulatory provisions and lower volumes. EBIT in the first quarter of 2012 was relatively unchanged from 2011 as the aforementioned revenue increase was substantially offset by higher pension expense.

Revenues and EBIT of the real estate brokerage business improved by $22 million and $9 million, respectively, for the first quarter of 2012 compared to the first quarter of 2011 primarily due to a 14% increase in closed sales transactions, partially offset by a 5% decrease in average home sale prices.

Marmon

Through Marmon, we operate approximately 150 manufacturing and service businesses that operate independently within eleven diverse business sectors. Marmon’s first quarter 2012 revenues were approximately $1.8 billion, an increase of $119 million (7%) as compared to the first quarter of 2011. Overall, eight of the eleven business sectors generated increased revenues compared to the first quarter of 2011. Nearly half of the increase in revenues was attributable to recent bolt-on business acquisitions in the Crane Services, Highway Technologies and Engineered Wire & Cable sectors. In addition, the Transportation Services & Engineered Products, Distribution Services and Highway Technologies sectors (excluding acquisitions) generated significant revenue increases in the first quarter of 2012. The revenue increases were partially offset by significantly lower comparative revenues from the Flow Products and Retail Store Fixtures sectors. The Retail Store Fixtures sector continues to be impacted by significantly reduced activity of its major customer. The Flow Products revenues were impacted by lower copper prices, as well as by lower volume from its industrial customers.

Pre-tax earnings were $269 million in the first quarter of 2012, an increase of $47 million (21%) as compared to the first quarter of 2011. All but two sectors produced comparable or increased pre-tax earnings in the first quarter of 2012 as compared to the first quarter of 2011. The aforementioned business acquisitions accounted for approximately 20% of the pre-tax earnings increase in the first quarter of 2012. In addition, the Transportation Services & Engineered Products, Distribution Services, Highway Technologies and Engineered Wire & Cable sectors (excluding acquisitions) generated significant increases in pre-tax earnings, while earnings from the Retail Store Fixtures and Flow Products sectors declined for the reasons indicated above. Pre-tax earnings as a percent of revenues was 15.0% in the first quarter of 2012 compared to 13.3% in the first quarter of 2011. The improvement in earnings as a percent of revenues reflects the continued emphasis of Marmon’s business model which fosters margin growth. In addition to the impact of recent acquisitions, improvements in revenues and pre-tax earnings generally reflected continued strength in some of Marmon’s end markets, increased product innovation and ongoing efforts to control overhead costs.

McLane Company

Through McLane, we operate a wholesale distribution business that provides grocery and non-food products to retailers, convenience stores and restaurants. McLane’s business is marked by high sales volume and very low profit margins. McLane’s significant customers include Wal-Mart, 7-Eleven and Yum! Brands. Approximately 30% of McLane’s annual revenues are attributable to Wal-Mart. A curtailment of purchasing by Wal-Mart or another of its significant customers could have a material adverse impact on McLane’s periodic revenues and earnings. In 2010, McLane acquired Empire Distributors, based in Georgia and North Carolina, and Horizon Wine and Spirits Inc., based in Tennessee. Empire and Horizon are wholesale distributors of distilled spirits, wine and beer.

Revenues for the first quarter of 2012 were $8,073 million, an increase of $306 million (3.9%) over 2011, reflecting revenue increases from the grocery, foodservice and beverage distribution operations. Pre-tax earnings in the first quarter of 2012 were $102 million, an increase of $20 million over 2011. The increase in pre-tax earnings was primarily attributable to the favorable impact of changes in LIFO inventory reserves and comparatively lower professional fees.

Other manufacturing

Our other manufacturing businesses include several manufacturers of building products (Acme Building Brands, Benjamin Moore, Johns Manville, Shaw and MiTek) and apparel (led by Fruit of the Loom which includes the Russell athletic apparel and sporting goods business and the Vanity Fair Brands women’s intimate apparel business). Also included in this group are Forest River, a leading manufacturer of recreational vehicles, IMC Metalworking Companies (“ISCAR”), an industry leader in the metal cutting tools business with operations worldwide and CTB, a manufacturer of equipment and systems for the livestock and agricultural industries. Other manufacturing businesses also include The Lubrizol Corporation (“Lubrizol”), a specialty chemical manufacturer that we acquired on September 16, 2011.

Revenues from our other manufacturing activities for the first quarter of 2012 were $6,504 million, an increase of $1,951 million (43%) over 2011. In 2012, revenues from Lubrizol were $1,576 million. For the first quarter of 2012, we also experienced revenue increases from sales of building products (7.5%), recreational vehicles (19.6%) and apparel (6.5%). While revenues in 2012 from the building products group increased over 2011, these businesses, generally, continue to be negatively impacted by slow construction activity, particularly in the single-family housing markets.

Pre-tax earnings of our other manufacturing businesses in the first quarter of 2012 were $815 million, an increase of $371 million (84%) versus 2011, which was primarily due to the inclusion of Lubrizol’s earnings. Excluding the impact of Lubrizol, earnings in the first quarter of 2012 increased $72 million (16%) compared to 2011. The increase was primarily attributable to increased earnings from our building products businesses. With the exception of bricks, all of our building products businesses as well as ISCAR and several of our other diverse manufacturing businesses generated higher earnings in 2012 over 2011 somewhat offset by decreased earnings from our apparel businesses. Also, several of our manufacturers experienced higher commodity costs of certain raw materials, as well as higher energy costs over the past year. As a result, we have increased selling prices for certain products. To the extent that costs continue to stay at current elevated levels or increase, further selling price actions will likely be necessary.

Other service

Our other service businesses include NetJets, the world’s leading provider of fractional ownership programs for general aviation aircraft and FlightSafety, a provider of high technology training to operators of aircraft. Among the other businesses included in this group are: TTI, a leading electronic components distributor; Business Wire, a leading distributor of corporate news, multimedia and regulatory filings; Pampered Chef, a direct seller of high quality kitchen tools; Dairy Queen, which licenses and services a system of over 6,100 stores that offer prepared dairy treats and food; Buffalo News and the Omaha World-Herald (acquired at the end of 2011), publishers of daily and Sunday newspapers; and businesses that provide management and other services to insurance companies.

Revenues of our other service businesses were $2,047 million in the first quarter of 2012, an increase of $79 million (4%) compared to 2011. Pre-tax earnings were $205 million in the first quarter of 2012, an increase of $5 million (2.5%) versus 2011. The increase in revenues in 2012 was primarily attributable to the inclusion of the Omaha World-Herald and revenue increases from FlightSafety and NetJets. The increase in earnings in 2012 reflected increased earnings at NetJets, partially offset by lower earnings from TTI. The improvement in comparative first quarter earnings of NetJets, was largely due to fees incurred in the first quarter of 2011 to cancel certain aircraft purchases under a purchase agreement entered into several years earlier and lower foreign currency exchange losses affecting operations outside of the United States in 2012. In the first quarter of 2011, TTI experienced very strong demand, which favorably impacted revenues and earnings. Over the last half of 2011 and into the first quarter of 2012, demand softened and price competition intensified, which put downward pressure on TTI’s margins. As a result, TTI’s pre-tax earnings for the first quarter of 2012 declined 22% versus the first quarter of 2011.

Manufacturing, Service and Retailing (Continued)

Retailing

Our retailing operations consist of four home furnishings businesses (Nebraska Furniture Mart, R.C. Willey, Star Furniture and Jordan’s), three jewelry businesses (Borsheims, Helzberg and Ben Bridge) and See’s Candies. Revenues and pre-tax earnings in the first quarter of 2012 from the retailing businesses increased $58 million (8%) and $18 million (58%), respectively, over the first quarter of 2011. First quarter 2012 revenues of the home furnishings businesses increased $42 million (9%) over 2011, while pre-tax earnings in 2012 increased $13 million (53%).

Finance and Financial Products

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

	First Quarter
	Revenues				Earnings
	2012		2011		2012		2011
Manufactured housing and finance	$	718	$	671	$	40	$	32
Furniture/transportation equipment leasing		176		169		26		21
Other		65		73		97		103
	$	959	$	913
Pre-tax earnings						163		156
Income taxes and noncontrolling interests						59		60
					$	104	$	96

Revenues of Clayton Homes in the first quarter of 2012 were $718 million, an increase of $47 million (7%) over 2011. Revenues from home sales in the first quarter of 2012 increased $63 million (22%) over 2011, due to a 32% increase in units sold partially offset by a lower average price per unit due primarily to product mix changes. Financial services revenues for the first quarter of 2012 declined $16 million from 2011, due primarily to lower interest income from installment loans. Installment loan and finance receivable balances were approximately $12.7 billion, a decrease of approximately $200 million from December 31, 2011. Clayton Homes pre-tax earnings were $40 million for the first quarter of 2012, an increase of $8 million (25%) over 2011, which was primarily attributable to the increase in unit sales and gross sales margins, partially offset by lower financial services earnings.

Clayton Homes’ operating results continue to be negatively affected by the ongoing soft housing markets and the surplus of traditional single family homes for sale. In addition, our manufactured housing programs continue to operate at a competitive disadvantage compared to traditional single family housing markets, which have been receiving significant interest rate subsidies from the U.S. government through government agency insured mortgages. For the most part, these subsidies are not available to factory built homes. Nevertheless, Clayton Homes remains the largest manufactured housing business in the United States and we believe that it will continue to operate profitably, even under the current conditions.

Revenues and pre-tax earnings of CORT and XTRA increased slightly in 2012 compared to 2011. The increases primarily reflected higher furniture rental income.

Earnings from our other finance business activities include investment income from a portfolio of fixed maturity and equity investments and from a small portfolio of long-held commercial real estate loans. In addition, other earnings include income from interest rate spreads charged to Clayton Homes on borrowings (approximately $11.3 billion as of March 31, 2012) by a Berkshire financing subsidiary. The borrowings were made to fund the loans to Clayton Homes. A corresponding charge is reflected in Clayton Homes’ earnings. In addition, other finance business earnings for the first quarter include guaranty fee income of $9 million in 2012 and $11 million in 2011 from NetJets. Corresponding expenses are recorded by NetJets, which reduced its earnings in both periods.

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

Investment and Derivative Gains/Losses

A summary of investment and derivative gains and losses and other-than-temporary impairment losses on investments follows. Amounts are in millions.

	First Quarter
	2012			2011
Investment gains/losses	$	231		$	99
Other-than-temporary impairment losses on investments		(337	)		(506	)
Derivative gains/losses		1,002			271
Gains/losses before income taxes and noncontrolling interests		896			(136	)
Income taxes and noncontrolling interests		316			(54	)
Net gains/losses	$	580		$	(82	)

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

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 our management does not consider investment gains and losses in a given period as necessarily meaningful or useful in evaluating periodic earnings, we are providing information to explain the nature of such gains and losses when they are reflected in earnings.

Other-than-temporary impairment (“OTTI”) losses in the first quarter of 2012 were related to our investments in Texas Competitive Electric Holdings bonds. In 2011, OTTI losses related to our investments in Kraft Foods ($169 million) and Wells Fargo ($337 million). The OTTI losses recorded in the first quarters of 2012 and 2011 had no impact whatsoever on the asset values recorded in our Consolidated Balance Sheets or on our consolidated shareholders’ equity as of March 31, 2012 and 2011. Although we have periodically recorded OTTI losses in earnings in the past, we continue to hold positions in many of these securities. The recognition of such losses in earnings rather than in accumulated other comprehensive income does not necessarily indicate that sales are imminent or planned and sales ultimately may not occur for numerous years or even decades. Furthermore, the recognition of OTTI losses 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.

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. Security prices may remain below cost for a period of time that may be deemed excessive from the standpoint of interpreting existing accounting rules, even though other factors suggest that the prices will eventually recover. As a result, accounting regulations may require that we recognize OTTI losses in earnings in instances where we may strongly believe that the market price of the impaired security will recover to at least our original cost and where we possess the ability and intent to hold the security until, at least, that time.

As of March 31, 2012, unrealized losses on our investments in equity securities (determined on an individual purchase lot basis) were $274 million. Unrealized losses averaged 8% of cost. In our judgment, the future earnings potential and underlying business economics of these companies are favorable and we possess the ability and intent to hold these securities until their prices recover. Changing market conditions and other facts and circumstances may change the business prospects of these issuers as well as our ability and intent to hold these securities until their prices recover.

Our derivative contracts generated gains of $1,002 million in the first quarter of 2012 and $271 million in the first quarter of 2011. Derivative gains/losses primarily represent the changes in fair value of our credit default and equity index put option contracts. The periodic changes in the fair values of these contracts can be significant, reflecting the volatility of underlying equity and credit markets. Our ultimate payment obligations, if any, under our remaining equity index put option contracts will be determined as of the contract expiration dates, which begin in 2018.

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

Investment and Derivative Gains/Losses (Continued)

In the first quarter of 2012, our equity index put option contracts produced gains of $689 million, due primarily to higher equity prices, partially offset by lower interest rate assumptions. In the first quarter of 2011, gains from our equity index put option contracts of $223 million were primarily due to higher interest rate assumptions. Our credit default contracts generated gains of $340 million and $70 million in the first quarters of 2012 and 2011, respectively. The gains in both periods were primarily due to the narrowing of credit default spreads as well as the passage of time. We paid losses of $62 million in the first quarter of 2012 with respect to our corporate high yield contracts.

Financial Condition

Our balance sheet continues to reflect significant liquidity and a strong capital base. Our consolidated shareholders’ equity at March 31, 2012 was $176.0 billion, an increase of $11.1 billion from December 31, 2011. Consolidated cash and investments of insurance and other businesses approximated $167.3 billion at March 31, 2012 including cash and cash equivalents of $33.6 billion. These assets are held predominantly in our insurance businesses. On January 31, 2012, we issued an additional $1.7 billion of parent company senior unsecured notes, the proceeds of which were used to fund the repayment of $1.7 billion of notes that matured in February 2012.

In late September 2011, our Board of Directors authorized Berkshire Hathaway to repurchase Class A and Class B shares of Berkshire at prices no higher than a 10% premium over the book value of the shares. Berkshire may repurchase shares in open market purchases or through privately negotiated transactions, at management’s discretion. The repurchase program is expected to continue indefinitely, but does not obligate Berkshire to repurchase any dollar amount or number of Class A or Class B shares. Berkshire plans to use cash on hand to fund repurchases and repurchases will not be made if they would reduce Berkshire’s consolidated cash equivalent holdings below $20 billion. Financial strength and redundant liquidity will always be of paramount importance at Berkshire. To date, share repurchases have been insignificant.

Our railroad, utilities and energy businesses (conducted by BNSF and MidAmerican) maintain very large investments in capital assets (property, plant and equipment) and will regularly make capital expenditures in the normal course of business. In the first quarter of 2012, MidAmerican’s capital expenditures were $756 million and BNSF’s capital expenditures were $787 million. For the remainder of 2012, MidAmerican’s forecasted capital expenditures are $3.0 billion, while BNSF’s forecasted capital commitments are approximately $3.1 billion. Future capital expenditures are expected to be funded from cash flows from operations and debt issuances. In 2012, BNSF issued debt of $1.25 billion with maturities in 2022 and 2042, and its outstanding debt increased $1.2 billion to $13.8 billion as of March 31, 2012. In 2012, MidAmerican’s new borrowings were $1.6 billion and its aggregate outstanding borrowings increased $783 million to $20.7 billion as of March 31, 2012. MidAmerican and BNSF have aggregate debt and capital lease maturities over the remainder of 2012 of $1.6 billion. Berkshire has committed until February 28, 2014 to provide up to $2 billion of additional capital to MidAmerican to permit the repayment of its debt obligations or to fund its regulated utility subsidiaries. Berkshire does not guarantee the repayment of debt issued by BNSF, MidAmerican or any of their subsidiaries.

Assets of the finance and financial products businesses, which consisted primarily of loans and finance receivables, fixed maturity securities, other investments and cash and cash equivalents, were approximately $25.5 billion as of March 31, 2012 and $25.0 billion at December 31, 2011. Liabilities were approximately $24.0 billion as of March 31, 2012 and $25.4 billion as of December 31, 2011. As of March 31, 2012, notes payable and other borrowings of $13.7 billion included approximately $11.3 billion of notes issued by BHFC. In January 2012, $250 million of BHFC notes matured and an additional $2.45 billion will mature in the second and third quarters of 2012. We currently intend to issue new debt through BHFC to replace some or all of the BHFC debt maturing in 2012. The proceeds from the BHFC notes are used to finance originated and acquired loans of Clayton Homes. The full and timely payment of principal and interest on the BHFC notes is guaranteed by Berkshire.

We regularly access the credit markets, particularly through our parent company and through our railroad, utilities and energy and the finance and financial products businesses. Restricted access to credit markets at affordable rates in the future could have a significant negative impact on our operations.

On July 21, 2010, President Obama signed into law financial regulatory reform legislation, known as the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Reform Act”). The Reform Act reshapes financial regulations in the United States by creating new regulators, regulating new markets and market participants and providing new enforcement powers to regulators. Virtually all major areas of the Reform Act will be subject to regulatory interpretation and implementation rules requiring rulemaking that may take several years to complete.

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

Financial Condition (Continued)

We are party to several equity index put option and credit default contracts as described in Note 12 to the Consolidated Financial Statements. With limited exception, these contracts contain no collateral posting requirements under any circumstances, including changes in either the fair value or intrinsic value of the contracts or a downgrade in Berkshire’s credit ratings. Substantially all of these contracts were entered into prior to December 31, 2008. At March 31, 2012, the net liabilities recorded for such contracts were approximately $8.9 billion and our collateral posting requirements were $45 million. With respect to such collateral requirements, we receive the income attributable to such collateral or, in certain instances, interest credit from the counterparty. Although the ultimate outcome of the regulatory rulemaking proceedings described in the preceding paragraph cannot be predicted with certainty, we do not believe that the provisions of the Reform Act that concern collateral requirements apply to derivatives contracts that were entered into prior to the enactment of the Reform Act, as ours were. As such, although the Reform Act may adversely affect some of our business activities, it is not currently expected to have a material impact on our consolidated financial results or financial condition.

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 reflected in our Consolidated Balance Sheets, such as notes payable, require future payments on contractually specified dates and in fixed and determinable amounts. The timing and/or amount of the payment of other obligations, such as losses arising from unpaid property and casualty loss insurance contracts and credit default and equity index put option derivatives contracts, are contingent upon the outcome of future events. Actual payments will likely vary, perhaps significantly, from the liability estimates currently recorded in the Consolidated Balance Sheet. Other obligations pertain to the acquisition of goods or services in the future, which are not currently reflected in the financial statements, such as minimum rentals under operating leases. Our contractual obligations as of March 31, 2012 were 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, 2011.

Critical Accounting Policies

Certain accounting policies require us to make estimates and judgments regarding transactions that have occurred and ultimately will be settled several years in the future or concerning the recoverability of assets. Amounts recognized in the financial statements from such estimates are necessarily based on assumptions about numerous factors involving varying, and possibly significant, degrees of judgment and uncertainty. Accordingly, the amounts currently recorded in the financial statements may prove, with the benefit of hindsight, to be inaccurate. 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, 2011 for additional discussion regarding these estimates.

Our Consolidated Balance Sheet as of March 31, 2012 includes estimated liabilities for unpaid losses from property and casualty insurance and reinsurance contracts of $63.7 billion. Due to the inherent uncertainties in the process of establishing loss reserve amounts, the actual ultimate claim amounts will likely differ from the currently recorded amounts. A very small percentage change in estimates of this magnitude will result in a material effect on reported earnings. The effects from changes in these estimates are recorded as a component of losses incurred in the period of the change.

Our Consolidated Balance Sheet as of March 31, 2012 includes goodwill of acquired businesses of $53.2 billion. We evaluate goodwill for impairment at least annually and conducted our most recent annual review during the fourth quarter of 2011. Although we believe that the goodwill reflected in the Consolidated Balance Sheet as of March 31, 2012 is not impaired, goodwill may subsequently become impaired as a result of changes in facts and circumstances affecting the valuation of the reporting unit. A goodwill impairment charge could have a material effect on periodic net earnings.

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

Critical Accounting Policies (Continued)

Our Consolidated Balance Sheets include significant amounts of derivative contract liabilities that are measured at fair value. Our significant derivative contract exposures are concentrated in credit default and equity index put option contracts. These contracts were primarily entered into in over-the-counter markets and certain elements in the terms and conditions of such contracts are not standardized. In particular, we are not required to post collateral under most of our contracts. Furthermore, there is no source of independent data available to us showing trading volume and actual prices of completed transactions. As a result, the values of these liabilities are primarily based on valuation models, discounted cash flow models or other valuation techniques that are believed to be used by market participants. Such models or other valuation techniques may use inputs that are observable in the marketplace, while others are unobservable. Unobservable inputs require us to make certain projections and assumptions about the information that would be used by market participants in establishing prices. Considerable judgment may be required in making assumptions, including the selection of interest rates, default and recovery rates and volatility. Changes in assumptions may have a significant effect on values.

Information concerning new accounting pronouncements is included in Note 2 to the 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 guaranties 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 important 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, 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.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

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 March 31, 2012, there are no material changes in the market risks described in Berkshire’s Annual Report on Form 10-K for the year ended December 31, 2011.

Item 4. Controls and Procedures

As of the end of the period covered by this Quarterly Report on Form 10-Q, the Corporation carried out an evaluation, under the supervision and with the participation of the Corporation’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 Corporation’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 Corporation’s disclosure controls and procedures are effective in timely alerting them to material information relating to the Corporation (including its consolidated subsidiaries) required to be included in the Corporation’s periodic SEC filings. During the quarter, there have been no significant changes in the Corporation’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 party in a variety of legal actions arising out of the normal course of business. In particular, such legal actions affect our insurance and reinsurance businesses. Such litigation generally seeks 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.

Item 1A. Risk Factors

Our significant business risks are described in Item 1A to Form 10-K for the year ended December 31, 2011 to which reference is made herein.

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

On September 26, 2011, Berkshire announced a common stock repurchase program where Berkshire’s Board of Directors authorized Berkshire to repurchase Class A and Class B shares of the Company at prices no higher than a 10% premium over the book value of the shares. Berkshire’s Board of Directors’ authorization does not specify a maximum number of shares to be purchased. However, repurchases will not be made if they would reduce Berkshire’s consolidated cash equivalent holdings below $20 billion. The repurchase program is expected to continue indefinitely and the amount of purchases will depend entirely upon the levels of cash available, the attractiveness of investment and business opportunities either at hand or on the horizon and the degree of discount from 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. There were no share repurchases during the first quarter of 2012.
