Berkshire Hathaway Inc. (“Berkshire,” “Company” or “Registrant”) is a holding company owning subsidiaries engaged in a number of diverse business activities. The most important of these are insurance businesses conducted on both a primary basis and a reinsurance basis, a freight rail transportation business and a group of utility and energy generation and distribution businesses. Berkshire also owns and operates a large number of other businesses engaged in a variety of activities, as identified herein. Berkshire is domiciled in the state of Delaware, and its corporate headquarters are located in Omaha, Nebraska.

Berkshire’s 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 Berkshire’s corporate headquarters in the day-to-day business activities of the operating businesses. Berkshire’s corporate office senior management participates in and is ultimately responsible for significant capital allocation decisions, investment activities and the selection of the Chief Executive to head each of the operating businesses. It also is responsible for establishing and monitoring Berkshire’s corporate governance practices, including, but not limited to, communicating the appropriate “tone at the top” messages to its employees and associates, monitoring governance efforts, including those at the operating businesses, and participating in the resolution of governance-related issues as needed.

Berkshire and its consolidated subsidiaries employ approximately 316,000 people world-wide. Berkshire’s corporate headquarters has 25 employees.

Insurance and Reinsurance Businesses

Berkshire’s insurance and reinsurance business activities are conducted through numerous domestic and foreign-based insurance entities. Berkshire’s insurance businesses provide insurance and reinsurance of property and casualty risks world-wide and also reinsure life, accident and health risks world-wide.

In primary (or direct) insurance activities, the insurer assumes the risk of loss from persons or organizations that are directly subject to the risks. Such risks may relate to property, casualty (or liability), life, accident, health, financial or other perils that may arise from an insurable event. In reinsurance activities, the reinsurer assumes defined portions of risks that other primary insurers or reinsurers have assumed in their own insuring activities.

Reinsurance contracts are normally classified as treaty or facultative contracts. Treaty reinsurance refers to reinsurance coverage for all or a portion of a specified class of risks ceded by the primary insurer, while facultative reinsurance involves coverage of specific individual risks. Reinsurance contracts are further classified as quota-share or excess. Under quota-share (proportional or pro-rata) reinsurance, the reinsurer shares proportionally in the original premiums, losses and expenses of the primary insurer or reinsurer. Excess (or non-proportional) reinsurance provides for the indemnification of the primary insurer or reinsurer for all or a portion of the loss in excess of an agreed upon amount or “retention.” Both quota-share and excess reinsurance contracts may provide for aggregate limits of indemnification.

Insurance and reinsurance are generally subject to regulatory oversight throughout the world. Except for regulatory considerations, there are virtually no barriers to entry into the insurance and reinsurance industry. Competitors may be domestic or foreign, as well as licensed or unlicensed. The number of competitors within the industry is not known. Insurers and reinsurers compete on the basis of reliability, financial strength and stability, financial ratings, underwriting consistency, service, business ethics, price, performance, capacity, policy terms and coverage conditions.

Insurers and reinsurers based in the United States are subject to regulation by their states of domicile and by those states in which they are licensed or write policies on an admitted basis. The primary focus of regulation is to assure that insurers are financially solvent and that policyholder interests are otherwise protected. States establish minimum capital levels for insurance companies and establish guidelines for permissible business and investment activities. States have the authority to suspend or revoke a company’s authority to do business as conditions warrant. States regulate the payment of dividends by insurance companies to their shareholders and other transactions with affiliates. Dividends and capital distributions and other transactions of extraordinary amounts are subject to prior regulatory approval.

Insurers may market, sell and service insurance policies in the states where they are licensed. These insurers are referred to as admitted insurers. Admitted insurers are generally required to obtain regulatory approval of their policy forms and premium rates. Non-admitted insurance markets have developed to provide insurance that is otherwise unavailable through admitted insurers. Non-admitted insurance, often referred to as “excess and surplus” lines, is procured by either state-licensed surplus lines brokers who place risks with insurers not licensed in that state or by the insured party’s direct procurement from non-admitted insurers. Non-admitted insurance is subject to considerably less regulation with respect to policy rates and forms. Reinsurers are normally not required to obtain regulatory approval of premium rates and policy forms.

The insurance regulators of every state participate in the National Association of Insurance Commissioners (“NAIC”). The NAIC adopts forms, instructions and accounting procedures for use by U.S. insurers and reinsurers in preparing and filing annual statutory financial statements. However, an insurer’s state of domicile has ultimate authority over these matters. In addition to its activities relating to the annual statement, the NAIC develops or adopts statutory accounting principles, model laws, regulations and programs for use by its members. Such matters deal with regulatory oversight of solvency, risk management, compliance with financial regulation standards and risk-based capital reporting requirements.

Berkshire’s insurance companies maintain capital strength at exceptionally high levels. This strength differentiates Berkshire’s insurance companies from their competitors. Collectively, the aggregate statutory surplus of Berkshire’s U.S. based insurers was approximately $129 billion at December 31, 2014. All of Berkshire’s major insurance subsidiaries are rated AA+ by Standard & Poor’s and A++ (superior) by A.M. Best with respect to their financial condition and operating performance.

The Terrorism Risk Insurance Act of 2002 established within the Department of the Treasury a Terrorism Insurance Program (“Program”) for commercial property and casualty insurers by providing federal reinsurance of insured terrorism losses. The Program currently extends to December 31, 2020 through other Acts, most recently the Terrorism Risk Insurance Program Reauthorization Act of 2015 (the “2015 TRIA Reauthorization”). Hereinafter these Acts are collectively referred to as TRIA. Under TRIA, the Department of the Treasury is charged with certifying “acts of terrorism.” In 2015, coverage under TRIA occurs when the industry insured loss for certified events occurring during a calendar year exceeds $100 million. Under the 2015 TRIA Reauthorization, the level of insured losses for certified events occurring during a calendar year required to trigger coverage under TRIA will increase to $120 million in 2016 and increase annually thereafter by $20 million per year until the level of insured losses required to trigger coverage reaches $200 million in 2020. To be eligible for federal reinsurance, insurers must make available insurance coverage for acts of terrorism, by providing policyholders with clear and conspicuous notice of the amount of premium that will be charged for this coverage and of the federal share of any insured losses resulting from any act of terrorism. Assumed reinsurance is specifically excluded from TRIA participation. TRIA currently also excludes certain forms of direct insurance (such as commercial auto, burglary, theft, surety and certain professional liability lines). Reinsurers are not required to offer terrorism coverage and are not eligible for federal reinsurance of terrorism losses.

In the event of a certified act of terrorism, the federal government will reimburse insurers (conditioned on their satisfaction of policyholder notification requirements) for 85% of their insured losses in excess of an insurance group’s deductible. Under the 2015 TRIA Reauthorization, the federal government’s reimbursement obligation will be reduced to 84% in 2016 and be decreased annually thereafter by 1% per year until the level of reimbursement is reduced to 80% in 2020. Under the Program the deductible is 20% of the aggregate direct subject earned premium for relevant commercial lines of business in the immediately preceding calendar year. The aggregate deductible in 2015 for Berkshire’s consolidated insurance and reinsurance businesses will be approximately $750 million. There is also an aggregate limit of $100 billion on the amount of the federal government coverage for each TRIA year.

Regulation of the insurance industry outside of the United States is subject to the laws and regulations of each country in which an insurer has operations or writes premiums. Some jurisdictions impose comprehensive regulatory requirements on insurance businesses, such as in the United Kingdom, where insurers are subject to regulation by the Prudential Regulation Authority and the Financial Conduct Authority and in Germany where insurers are subject to regulation by the Federal Financial Supervisory Authority (BaFin). Other jurisdictions may impose fewer requirements. In certain foreign countries, reinsurers are also required to be licensed by governmental authorities. These licenses may be subject to modification, suspension or revocation dependent on such factors as amount and types of insurance liabilities and minimum capital and solvency tests. The violation of regulatory requirements may result in fines, censures and/or criminal sanctions in various jurisdictions.

Table of Contents

Berkshire’s insurance underwriting operations are comprised of the following sub-groups: (1) GEICO and its subsidiaries, (2) General Re and its subsidiaries, (3) Berkshire Hathaway Reinsurance Group and (4) Berkshire Hathaway Primary Group. Except for retroactive reinsurance and structured settlement and annuity reinsurance products that generate significant amounts of up-front premiums along with estimated claims expected to be paid over very long periods of time creating “float” (see Investments section below), Berkshire expects to achieve a net underwriting profit over time and will reject inadequately priced risks. Underwriting profit is defined as earned premiums less associated incurred losses, loss adjustment expenses and underwriting and policy acquisition expenses. Underwriting profit does not include investment income earned from investments.

Berkshire’s insurance subsidiaries employ approximately 40,000 people in the aggregate. Additional information related to each of Berkshire’s four underwriting groups follows.

GEICO —GEICO is headquartered in Chevy Chase, Maryland and its insurance subsidiaries consist of: Government Employees Insurance Company, GEICO General Insurance Company, GEICO Indemnity Company, GEICO Casualty Company, GEICO Advantage Insurance Company, GEICO Choice Insurance Company, GEICO Secure Insurance Company and GEICO County Mutual Insurance Company. These companies primarily offer private passenger automobile insurance to individuals in all 50 states and the District of Columbia. In addition, GEICO insures motorcycles, all-terrain vehicles, recreational vehicles and small commercial fleets and acts as an agent for other insurers who offer homeowners, boat and life insurance to individuals. GEICO markets its policies primarily through direct response methods in which applications for insurance are submitted directly to the companies via the Internet or by telephone.

GEICO competes for private passenger auto insurance customers with other companies that sell directly to the customer as well as with companies that use agency sales forces. The automobile insurance business is highly competitive in the areas of price and service. Some insurance companies may exacerbate price competition by selling their products for a period of time at less than adequate rates. GEICO will not knowingly follow that strategy.

As a result of an aggressive advertising campaign and competitive rates, voluntary policies-in-force have increased about 39% over the past five years. GEICO was the second largest private passenger auto insurer in the United States in terms of premium volume in 2013. According to A.M. Best data for 2013, the five largest automobile insurers have a combined market share of 52%, with GEICO’s market share being approximately 10.4%. Since the publication of that data, management believes that GEICO’s current market share has grown to approximately 10.8%. Seasonal variations in GEICO’s insurance business are not significant. However, extraordinary weather conditions or other factors may have a significant effect upon the frequency or severity of automobile claims.

Private passenger auto insurance is stringently regulated by state insurance departments. As a result, it is difficult for insurance companies to differentiate their products. Competition for private passenger automobile insurance, which is substantial, tends to focus on price and level of customer service provided. GEICO’s cost-efficient direct response marketing methods and emphasis on customer satisfaction enable it to offer competitive rates and value to its customers. GEICO primarily uses its own claims staff to manage and settle claims.

The name and reputation of GEICO is a material asset and management protects it and other service marks through appropriate registrations.

General Re —General Re Corporation (“General Re”) is the holding company of General Reinsurance Corporation (“GRC”) and its subsidiaries and affiliates. GRC’s subsidiaries include General Reinsurance AG, a major international reinsurer based in Germany. General Re subsidiaries currently conduct business activities globally in 51 cities and provide insurance and reinsurance coverages throughout the world. General Re provides property/casualty insurance and reinsurance, life/health reinsurance and other reinsurance intermediary and risk management services, underwriting management and investment management services. General Re is one of the largest reinsurers in the world based on premium volume and shareholder capital.

Property/Casualty Reinsurance

General Re’s property/casualty reinsurance business in North America is conducted through GRC which is domiciled in Delaware and licensed in the District of Columbia and all states but Hawaii where it is an accredited reinsurer. Property/casualty operations in North America are headquartered in Stamford, Connecticut, and are also conducted through 16 branch offices in the U.S. and Canada. Reinsurance activities are marketed directly to clients without involving a broker or intermediary. Coverages are written primarily on an excess basis and under treaty and facultative contracts. In 2014, approximately 33% of net written premiums in North America related to casualty reinsurance coverages and 48% related to property reinsurance coverages.

Table of Contents

General Re’s property/casualty business in North America also includes specialty insurers (primarily the General Star and Genesis companies domiciled in Delaware and Connecticut). These specialty insurers underwrite primarily liability and workers’ compensation coverages on an excess and surplus basis and excess insurance for self-insured programs. In 2014, the specialty insurers represented approximately 19% of General Re’s North American property/casualty net written premiums.

General Re’s international property/casualty reinsurance business operations are conducted through internationally-based subsidiaries on a direct basis (via General Reinsurance AG as well as several other General Re subsidiaries and branches in 23 countries) and through brokers (primarily via Faraday, which owns the managing agent of Syndicate 435 at Lloyd’s and provides capacity and participates in 100% of the results of Syndicate 435). Coverages are written on both a quota-share and excess basis for multiple lines of property, aviation and casualty reinsurance. In 2014, international-based property/casualty operations principally wrote direct reinsurance in the form of treaties with lesser amounts written on a facultative basis.

Life/Health Reinsurance

General Re’s North American and international life, health, long-term care and disability reinsurance coverages are written on an individual and group basis. Most of this business is written on a proportional treaty basis, with the exception of the U.S. group health and disability business which is predominately written on an excess treaty basis. Lesser amounts of life and disability business are written on a facultative basis. The life/health business is marketed on a direct basis. In 2014, approximately 34% of life/health net premiums were written in the United States, 26% in Western Europe and the remaining 40% throughout the rest of the world.

Berkshire Hathaway Reinsurance Group —Berkshire Hathaway Reinsurance Group (“BHRG”) operations are based in Stamford, Connecticut. Business activities are conducted through numerous subsidiaries, led by National Indemnity Company (“NICO”) and Columbia Insurance Company (“Columbia”). BHRG provides principally excess and quota-share reinsurance to other property and casualty insurers and reinsurers. BHRG also offers life reinsurance and annuity contracts through Berkshire Hathaway Life Insurance Company of Nebraska (“BHLN”) and financial guaranty insurance through Berkshire Hathaway Assurance Corporation.

The type and volume of insurance and reinsurance business written by BHRG is dependent on current market conditions, including prevailing premium rates and coverage terms. The level of BHRG’s underwriting activities often fluctuates significantly from year to year depending on the perceived level of price adequacy in specific insurance and reinsurance markets as well as from the timing of particularly large reinsurance transactions.

BHRG underwrites traditional non-catastrophe property and casualty insurance and reinsurance, catastrophe excess-of-loss treaty and facultative reinsurance, and individual primary insurance policies on an excess-of-loss basis for primarily large or otherwise unusual discrete risks, referred to as “individual risk.” BHRG periodically participates in underwriting facilities with major brokers in the London Market through a wholly-owned subsidiary based in Great Britain. BHRG’s business is written through brokers or directly with the insured or reinsured.

A catastrophe excess-of-loss policy provides protection to the counterparty from the accumulation of primarily property losses arising from a single loss event or series of related events. The timing and magnitude of catastrophe loss events can produce extremely volatile periodic underwriting results. The extraordinary financial strength of NICO and Columbia are believed to be the primary reasons why BHRG has become a major provider of such coverages. This financial strength also provides opportunities to enter into exceptionally large quota-share and retroactive reinsurance transactions.

BHRG periodically assumes risks through NICO under retroactive reinsurance contracts. Retroactive reinsurance contracts afford protection to ceding companies against the adverse development of claims arising under policies issued in prior years. Coverage under such contracts is provided on an excess basis or for losses payable immediately after the inception of the contract. Coverage provided is normally subject to large aggregate limits of indemnification. Significant amounts of asbestos, environmental and latent injury claims may arise under these contracts.

Table of Contents

Notable retroactive reinsurance contracts include: (1) a policy written in 2007 between NICO and Equitas, a London based entity established to reinsure and manage the 1992 and prior years’ non-life liabilities of the Names or Underwriters at Lloyd’s of London, under which NICO provides up to $7 billion of reinsurance to Equitas in excess of its carried reserves; (2) a policy written in 2009 with Swiss Re and its affiliates, under which NICO agreed to provide up to 5 billion Swiss Francs of aggregate excess protection; (3) a policy written in 2010 with Continental Casualty Company, a subsidiary of CNA Financial Corporation (“CNA”), and several of CNA’s other insurance subsidiaries, under which NICO assumed the asbestos and environmental pollution liabilities subject to a maximum limit of indemnification of $4 billion; and (4) a policy written in 2011 with Eaglestone Reinsurance Company, a subsidiary of American International Group, Inc. (“AIG”), under which NICO agreed to reinsure the bulk of AIG’s U.S. asbestos liabilities up to a maximum limit of indemnification of $3.5 billion. In 2014, NICO entered into a reinsurance policy with Liberty Mutual Insurance Company (“LMIC”). The agreement provides that NICO reinsure substantially all of LMIC’s unpaid losses and allocated loss adjustment expense liabilities related to (a) asbestos and environmental claims from policies incepting prior to 2005 and (b) workers’ compensation claims occurrences arising prior to January 1, 2014, in excess of an aggregate retention of approximately $12.5 billion and subject to an aggregate limit of $6.5 billion.

In BHRG’s retroactive reinsurance business, the concept of time-value-of-money is an important element in establishing prices and contract terms, since the payment of losses under the insurance contracts are often expected to occur over very lengthy periods of time. Losses payable under these policies are normally expected to exceed premiums and therefore, produce underwriting losses. This business is accepted, in part, because of the large amounts of policyholder funds (“float”) generated for investment, the economic benefit of which will be reflected through investment results in future periods.

For many years, BHLN has offered annuity insurance products in structured settlements markets and reinsurance of annuity liabilities. Under these policies it receives upfront premiums and makes a stream of annuity payments in the future and payment streams often extend for decades. In 2010, BHLN also entered into a life reinsurance policy with Swiss Re Life & Health America Inc. (“SRLHA”), a subsidiary of Swiss Re, under which it reinsures a closed block of yearly renewable term reinsurance policies. At the end of 2010, BHLN acquired the life reinsurance business of Sun Life Assurance Company of Canada, which writes traditional life reinsurance business.

Beginning in 2013, BHRG assumed risks associated with guaranteed minimum death, income and other benefits under closed-blocks of variable annuity contracts. The risks assumed under these contracts may extend for decades and are subject to aggregate limits of indemnification. The profitability of this business is dependent on changes in investment values associated with the covered variable annuity contracts, and is also expected to be influenced by the behavior of annuity contract holders, as a result of options available under those contracts. In 2013, BHLN reinsured certain guaranteed minimum death benefit coverages on a closed-block of variable annuity reinsurance contracts that have been in run-off for a number of years under a 100% coinsurance reinsurance treaty with Connecticut General Life Insurance Company (“CGLIC”). The CGLIC contract will remain in force until the expiration of the underlying business, subject to an aggregate limit of indemnification of $3.82 billion.

Berkshire Hathaway Primary Group —The Berkshire Hathaway Primary Group (“BH Primary”) is a collection of independently managed primary insurance operations that provide a wide variety of insurance coverages to policyholders located principally in the United States. These various operations are discussed below.

NICO and certain affiliates (referred to as the National Indemnity Primary Group) underwrite motor vehicle and general liability insurance to commercial enterprises on both an admitted and excess and surplus basis. This business is written nationwide primarily through insurance agents and brokers and is based in Omaha, Nebraska.

A collection of insurance companies referred to as the “Berkshire Hathaway Homestate Companies” (“BHHC”) that primarily offer standalone workers’ compensation, commercial auto and commercial property coverages. BHHC has developed a national reach, with the ability to provide first-dollar and small to mid-range deductible workers’ compensation coverage to employers in all states, except those where coverage is available only through state operated workers’ compensation funds. As a result, the volume of workers’ compensation business written in recent years has grown significantly. BHHC serves a diverse client base. BHHC’s business is generated primarily through independent agents.

Applied also markets EquityComp ^® which is a workers’ compensation—only product with a profit sharing component targeted to medium-sized employers.

In 2012, NICO acquired Clal U.S. Holdings, which owns four insurance subsidiaries (collectively, the Berkshire Hathaway Guard Insurance Companies or “Guard”). Guard provides commercial property and casualty insurance coverage to small and mid-sized businesses and is based in Wilkes-Barre, Pennsylvania.

Boat America Corporation (“Boat”) owns Seaworthy Insurance Company and controls the Boat Owners Association of the United States (collectively “BoatU.S.”). BoatU.S. provides insurance, safety and other services to recreational watercraft owners and enthusiasts. Effective January 1, 2015, ownership of Boat was transferred to GEICO Corporation, and thereafter will be included as a component of GEICO. Central States Indemnity Company of Omaha, located in Omaha, Nebraska, primarily writes Medicare Supplement insurance and credit insurance.

Berkshire Hathaway Specialty Insurance (“BHSI”) was formed in April 2013. During 2014, BHSI provided primary and excess commercial property, casualty, healthcare professional liability, executive and professional lines, surety and travel insurance in the U.S. and Canada. In December 2014, BHSI established locally authorized branch offices in Singapore and Hong Kong. BHSI intends to continue to expand globally and open additional offices outside the U.S. in 2015. BHSI’s business is written on both an excess and surplus lines basis and an admitted basis in the U.S., and on a locally admitted basis outside the U.S. BHSI’s home office is located in Boston, with regional underwriting offices currently in Atlanta, Chicago, Los Angeles, New York, Singapore, Hong Kong and Toronto. BHSI writes business through wholesale and retail insurance brokers, as well as managing general agents.

Property and casualty loss liabilities

Berkshire’s property and casualty insurance companies establish liabilities for estimated unpaid losses and loss adjustment expenses with respect to claims occurring on or before the balance sheet date. Such estimates include provisions for reported claims or case estimates, provisions for incurred-but-not-reported (“IBNR”) claims and legal and administrative costs to settle claims. The estimates of unpaid losses and amounts recoverable under reinsurance are established and continually reviewed by using a variety of actuarial, statistical and analytical techniques. Reference is made to “Critical Accounting Policies,” included in Item 7 of this Report.

The table below presents the development of Berkshire’s net unpaid losses for property/casualty contracts from 2004 through 2013 and net unpaid loss data as of December 31, 2014. Data in the table related to acquisitions is included from the acquisition date forward. Berkshire’s management believes that the liabilities established as of December 31, 2014 are reasonable and adequate. However, due to the inherent uncertainties in the reserving process, it cannot be assured that such balances will ultimately prove to be adequate. Dollar amounts are in millions.

Table of Contents

The first section of the table reconciles the estimated liability for unpaid losses and loss adjustment expenses recorded at the balance sheet date for each of the indicated years from the liability reflected in Berkshire’s Consolidated Balance Sheet to the net amount, after reductions for amounts recoverable under ceded reinsurance, deferred charges on retroactive reinsurance contracts and loss reserve discounts.

Certain workers’ compensation loss liabilities are discounted for both statutory and GAAP reporting purposes at an interest rate of 4.5% per annum for claims occurring before 2003 and at 1% per annum for claims occurring thereafter. In addition, deferred charges are recorded as assets at the inception of retroactive reinsurance contracts for the excess, if any, of the estimated ultimate unpaid losses and loss adjustment expenses over the premiums received. The deferred charges are subsequently amortized over the expected claim payment period. Deferred charge amortization and loss reserve discount accretion are recorded as components of insurance losses and loss adjustment expenses incurred.

The second section of the table shows the re-estimated net unpaid losses, including the impact of changes in related reserve discount accretion and deferred charge amortization, based on experience as of the end of each succeeding year. The re-estimated amount also reflects the effect of loss payments and re-estimation of remaining ultimate unpaid liabilities. The line labeled “cumulative deficiency (redundancy)” represents the aggregate increase (decrease) in the initial estimates from the original balance sheet date through December 31, 2014. These amounts have been reported in earnings over time as components of losses and loss adjustment expenses and include accumulated reserve discount accretion and deferred charge amortization. Due to the significance of the deferred charges and reserve discounts, the cumulative changes in such balances that are included in the cumulative deficiency/redundancy amounts are also provided.

The redundancies or deficiencies shown in each column should be viewed independently of the other columns because redundancies or deficiencies arising in earlier years are included as components of redundancies or deficiencies in the more recent years. Liabilities assumed under retroactive reinsurance contracts are treated as occurrences in the year the policy incepted, as opposed to when the underlying losses actually occurred, which is prior to the policy inception date.

The third part of the table shows the cumulative amount of net losses and loss adjustment expenses paid with respect to recorded net liabilities as of the end of each succeeding year. While the information in the table provides a historical perspective on the adequacy of unpaid losses and loss adjustment expenses established in previous years, and of the subsequent payments of claims, it should not be assumed that historical experience will continue in the future.

Investments —Invested assets of insurance businesses derive from shareholder capital as well as funds provided from policyholders through insurance and reinsurance business (“float”). Float is an approximation of the amount of net policyholder funds available for investment. That term denotes the sum of unpaid losses and loss adjustment expenses, life, annuity and health benefit liabilities, unearned premiums and other policyholder liabilities less the sum of premium balances receivable, losses recoverable from reinsurance ceded, deferred policy acquisition costs, deferred charges on reinsurance contracts and related deferred income taxes. On a consolidated basis, the amount of float has grown from approximately $63 billion at the end of 2009 to approximately $84 billion at the end of 2014, primarily through internal growth. BHRG and General Re accounted for approximately 74% of the consolidated float as of December 31, 2014. Equally important as the amount of the float is its cost, represented by Berkshire’s periodic net underwriting gain or loss. The increases in the amount of float plus the substantial amounts of shareholder capital devoted to insurance and reinsurance activities have generated meaningful increases in the levels of investments and investment income over the past five years.

Investment portfolios of insurance subsidiaries include ownership of equity securities of other publicly traded companies which are concentrated in relatively few companies and relatively large amounts of fixed maturity securities and cash and cash equivalents. Fixed maturity investments consist of obligations of the U.S. Government, U.S. states and municipalities, mortgage-backed securities issued primarily by the three major U.S. Government and Government-sponsored agencies, as well as obligations of foreign governments and corporate obligations. Investment portfolios are primarily managed by Berkshire’s corporate office. Generally, there are no targeted investment allocation rates established by management with respect to investment activities. However, investment portfolios have historically included a greater proportion of equity investments than is customary in the insurance industry. Management may increase or decrease investments in response to perceived changes in opportunities for income or price appreciation relative to risks associated with the issuers of the securities.

Railroad Business

On February 12, 2010, Berkshire completed its acquisition of Burlington Northern Santa Fe Corporation through the merger of a wholly-owned merger subsidiary and Burlington Northern Santa Fe Corporation. The merger subsidiary was the surviving entity and was renamed Burlington Northern Santa Fe, LLC (“BNSF”). BNSF is based in Fort Worth, Texas, and through BNSF Railway Company operates one of the largest railroad systems in North America with approximately 32,500 route miles of track (excluding multiple main tracks, yard tracks and sidings) in 28 states, and also operates in three Canadian provinces. BNSF Railway owns approximately 23,000 route miles, including easements, and operates on approximately 9,500 route miles of trackage rights that permit BNSF Railway to operate its trains with its crews over other railroads’ tracks. As of December 31, 2014, the total BNSF Railway system, including single and multiple main tracks, yard tracks and sidings, consisted of approximately 51,000 operated miles of track, all of which are owned by or held under easement by BNSF Railway, except for approximately 10,500 miles operated under trackage rights. BNSF had approximately 48,000 employees at the end of 2014.

In serving the Midwest, Pacific Northwest, Western, Southwestern and Southeastern regions and ports of the country, BNSF transports a range of products and commodities derived from manufacturing, agricultural and natural resource industries. Over half of the freight revenues of BNSF are covered by contractual agreements of varying durations, while the balance is subject to common carrier published prices or quotations offered by BNSF. BNSF’s financial performance is influenced by, among other things, general and industry economic conditions at the international, national and regional levels. BNSF’s primary routes, including trackage rights, allow it to access major cities and ports in the western and southern United States as well as parts of Canada and Mexico. In addition to major cities and ports, BNSF efficiently serves many smaller markets by working closely with approximately 200 shortline partners. BNSF has also entered into marketing agreements with other rail carriers, expanding the marketing reach for each railroad and their customers. For the year ending December 31, 2014, approximately 31% of freight revenues were derived from consumer products, 28% from industrial products, 22% from coal and 19% from agricultural products.

Regulatory Matters

BNSF is subject to federal, state and local laws and regulations generally applicable to all of its businesses. Rail operations are subject to the regulatory jurisdiction of the Surface Transportation Board (“STB”) of the United States Department of Transportation (“DOT”), the Federal Railroad Administration of the DOT, the Occupational Safety and Health Administration (“OSHA”), as well as other federal and state regulatory agencies and Canadian regulatory agencies for operations in Canada. The STB has jurisdiction over disputes and complaints involving certain rates, routes and services, the sale or abandonment of rail lines, applications for line extensions and construction, and the merger with or acquisition of control of rail common carriers. The outcome of STB proceedings can affect the profitability of BNSF’s business.

The DOT and OSHA have jurisdiction under several federal statutes over a number of safety and health aspects of rail operations, including the transportation of hazardous materials. State agencies regulate some aspects of rail operations with respect to health and safety in areas not otherwise preempted by federal law. BNSF Railway is required to transport these commodities to the extent of its common carrier obligation.

Environmental Matters

BNSF’s rail operations, as well as those of its competitors, are also subject to extensive federal, state and local environmental regulation covering discharges to water, air emissions, toxic substances and the generation, handling, storage, transportation and disposal of waste and hazardous materials. This regulation has the effect of increasing the cost and liabilities associated with rail operations. Environmental risks are also inherent in rail operations, which frequently involve transporting chemicals and other hazardous materials.

Many of BNSF’s land holdings are and have been used for industrial or transportation-related purposes or leased to commercial or industrial companies whose activities may have resulted in discharges onto the property. As a result, BNSF is now subject to, and will from time to time continue to be subject to, environmental cleanup and enforcement actions. In particular, the federal Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), also known as the Superfund law, generally imposes joint and several liabilities for the cleanup and enforcement costs on current and former owners and operators of a site, without regard to fault or the legality of the original conduct. Accordingly, BNSF may be responsible under CERCLA and other federal and state statutes for all or part of the costs to clean up sites at which certain substances may have been released by BNSF, its current lessees, former owners or lessees of properties, or other third parties. BNSF may also be subject to claims by third parties for investigation, cleanup, restoration or other environmental costs under environmental statutes or common law with respect to properties they own that have been impacted by BNSF operations.

Competition

The business environment in which BNSF operates is highly competitive. Depending on the specific market, deregulated motor carriers and other railroads, as well as river barges, ships and pipelines in certain markets, may exert pressure on price and service levels. The presence of advanced, high service truck lines with expedited delivery, subsidized infrastructure and minimal empty mileage continues to affect the market for non-bulk, time-sensitive freight. The potential expansion of longer combination vehicles could further encroach upon markets traditionally served by railroads. In order to remain competitive, BNSF and other railroads continue to develop and implement operating efficiencies to improve productivity.

As railroads streamline, rationalize and otherwise enhance their franchises, competition among rail carriers intensifies. BNSF’s primary rail competitor in the Western region of the United States is the Union Pacific Railroad Company. Other Class I railroads and numerous regional railroads and motor carriers also operate in parts of the same territories served by BNSF. Based on weekly reporting by the Association of American Railroads, BNSF’s share of the western United States rail traffic in 2014 was approximately 48.3%.

Regulatory Matters

PacifiCorp, MEC and the Nevada Utilities are subject to comprehensive regulation by various federal, state and local agencies. The Federal Energy Regulatory Commission (“FERC”) is an independent agency with broad authority to implement provisions of the Federal Power Act, the Natural Gas Act (“NGA”), the Energy Policy Act of 2005 and other federal statutes. The FERC regulates rates for wholesale sales of electricity; transmission of electricity, including pricing and regional planning for the expansion of transmission systems; electric system reliability; utility holding companies; accounting and records retention; securities issuances; construction and operation of hydroelectric facilities; and other matters. The FERC also has the enforcement authority to assess civil penalties of up to $1 million per day per violation of rules, regulations and orders issued under the Federal Power Act. MEC is also subject to regulation by the Nuclear Regulatory Commission pursuant to the Atomic Energy Act of 1954, as amended, with respect to its ownership of the Quad Cities Nuclear Station.

With certain limited exceptions, BHE’s domestic utilities have an exclusive right to serve retail customers within their service territories and, in turn, have an obligation to provide service to those customers. In some jurisdictions, certain classes of customers may choose to purchase all or a portion of their energy from alternative energy suppliers, and in some jurisdictions retail customers can generate all or a portion of their own energy. Historically, state regulatory commissions have established retail electric and natural gas rates on a cost-of-service basis, which are designed to allow a utility an opportunity to recover what each state regulatory commission deems to be the utility’s reasonable costs of providing services, including a fair opportunity to earn a reasonable return on its investments based on its cost of debt and equity. The retail electric rates of PacifiCorp, MEC and the Nevada Utilities are generally based on the cost of providing traditional bundled services, including generation, transmission and distribution services.

Northern Powergrid (Northeast) and Northern Powergrid (Yorkshire) each charge fees for the use of their distribution systems that are controlled by a formula prescribed by the British electricity regulatory body, the Gas and Electricity Markets Authority. The current five-year price control period is scheduled to end March 31, 2015, and the next price control period is set for the eight-year period ending March 31, 2023.

The natural gas pipelines are subject to regulation by various federal, state and local agencies. The natural gas pipeline and storage operations of Northern Natural and Kern River are regulated by the FERC pursuant to the NGA and the Natural Gas Policy Act of 1978. Under this authority, the FERC regulates, among other items, (a) rates, charges, terms and conditions of service and (b) the construction and operation of interstate pipelines, storage and related facilities, including the extension, expansion or abandonment of such facilities. Interstate natural gas pipeline companies are also subject to regulations administrated by the Office of Pipeline Safety within the Pipeline and Hazardous Materials Safety Administration, an agency within the DOT. Federal pipeline safety regulations are issued pursuant to the Natural Gas Pipeline Safety Act of 1968, as amended, which establishes safety requirements in the design, construction, operation and maintenance of interstate natural gas pipeline facilities.

AltaLink is regulated by the AUC, pursuant to the Electric Utilities Act (Alberta), the Public Utilities Act (Alberta), the Alberta Utilities Commission Act (Alberta) and the Hydro and Electric Energy Act (Alberta). The AUC is an independent quasi-judicial agency with broad authority to impact AltaLink’s General Tariff Applications, rates, construction, operations and financing. Under the Electric Utilities Act, AltaLink prepares and files applications with the AUC for approval of tariffs to be paid by the AESO for the use of its transmission facilities, and the terms and conditions governing the use of those facilities. The AESO is the independent system operator in Alberta, Canada that oversees Alberta’s integrated electrical system (“AIES”) and wholesale electricity market. The AESO is responsible for directing the safe, reliable and economic operation of the AIES for the use of transmission facilities and the terms and conditions governing the use of those facilities.

Environmental Matters

BHE and its energy businesses are subject to federal, state, local and foreign laws and regulations regarding air and water quality, renewable portfolio standards, emissions performance standards, climate change, coal combustion byproduct disposal, hazardous and solid waste disposal, protected species and other environmental matters that have the potential to impact current and future operations. In addition to imposing continuing compliance obligations, these laws and regulations, such as the Federal Clean Air Act, provide regulators with the authority to levy substantial penalties for noncompliance including fines, injunctive relief and other sanctions.

The Federal Clean Air Act, as well as state laws and regulations impacting air emissions, provides a framework for protecting and improving the nation’s air quality and controlling sources of air emissions. These laws and regulations continue to be promulgated and implemented and will impact the operation of BHE’s generating facilities and require them to reduce emissions at those facilities to comply with the requirements.

Renewable portfolio standards have been established by certain state governments and generally require electricity providers to obtain a minimum percentage of their power from renewable energy resources by a certain date. Utah, Oregon, Washington, California, Iowa and Nevada have adopted renewable portfolio standards. In addition, the potential adoption of state or federal clean energy standards, which include low-carbon, non-carbon and renewable electricity generating resources, may also impact electricity generators and natural gas providers.

Comprehensive climate change legislation has not been adopted by Congress; however, regulation of greenhouse gas emissions under various provisions of the Federal Clean Air Act has continued since the Environmental Protection Agency’s December 2009 findings that greenhouse gas emissions threaten public health and welfare. Since that determination, significant sources of greenhouse gas emissions have been required to report their greenhouse gas emissions and to undergo a best available control technology determination in conjunction with permitting greenhouse gas emissions. As part of President Obama’s Climate Action Plan issued in June 2013, the Environmental Protection Agency was required to re-propose by September 2013 greenhouse gas new source performance standards that had originally been proposed in 2012 for new fossil-fueled power plants. The re-proposed standards for new sources were released in September 2013 and generally propose a standard of 1,000 pounds of carbon dioxide per megawatt hour for natural gas-fueled combustion turbines and 1,100 pounds of carbon dioxide per megawatt hour for coal-fueled units. In addition, the Climate Action Plan required the Environmental Protection Agency to issue proposed standards or guidelines to address greenhouse gas emissions from existing fossil-fueled electric generating units by June 2014, to finalize those standards or guidelines by June 2015, and to require states to submit implementation plans by June 2016. The proposed guidelines were released by the Environmental Protection Agency in June 2014, and set state-by-state emission targets for carbon dioxide based on the application of the “Best System of Emission Reduction,” consisting of four building blocks: (1) a 6% heat rate improvement at coal-fueled units; (2) re-dispatch of natural gas combined cycle units up to a 70% capacity factor; (3) increased deployment of renewable and non-carbon generation; and, (4) increased deployment of end use energy efficiency. With a 2020 effective date, the proposed guidelines would achieve a reduction in carbon dioxide emissions from existing fossil-fueled electric generating units of 30% below 2005 levels by 2030. The public comment period closed December 1, 2014, and the Environmental Protection Agency is expected to issue its final guidelines to address carbon dioxide emissions from existing fossil-fueled electric generating units in the summer of 2015 at the same time the agency releases the final new source performance standards for modified and new sources.

In November 2014, President Obama announced a climate agreement with China in which the U.S. agreed to reduce greenhouse gas emissions 26-28% by 2025 from 2005 levels and China agreed that its emissions would peak by 2030 and it would aim to have 20% of its energy sources be non-carbon. While the discussions continue at the federal and international level over the direction of climate change policy, several states have continued to implement state-specific laws or regional initiatives to mitigate greenhouse gas emissions.

The impact of future federal, regional, state and international accords, legislation, regulation or judicial proceedings related to climate change cannot be quantified in any meaningful range at this time. New requirements limiting greenhouse gas emissions could have a material adverse impact on BHE and its subsidiaries, depending on the timing and scope of such requirements.

BHE continues to take actions to mitigate greenhouse gas emissions. For example, as of December 31, 2014, BHE subsidiaries owned 5,168 megawatts of wind-powered generating capacity in operation and under construction, which when completed is estimated to cost over $9 billion, and 1,286 megawatts of solar generating capacity in operation and under construction, which when completed is estimated to cost approximately $6 billion.

Non-Energy Businesses

U.S.-grown cotton and polyester fibers are the main raw materials used in the manufacturing of FOL’s apparel products and are purchased from a limited number of third-party suppliers. Management currently believes there are readily available alternative sources of raw materials. However, if relationships with suppliers cannot be maintained or delays occur in obtaining alternative sources of supply, production could be adversely affected, which could have a corresponding adverse effect on results of operations. Additionally, raw materials are subject to price volatility caused by weather, supply conditions, government regulations, economic climate and other unpredictable factors. FOL has secured contracts to purchase cotton to meet the majority of its production plans for 2015. In 2013 and 2014, cotton market prices were in the range of $0.69 to $0.93 per pound which approximates the ten year average price.

Financing is offered through its finance subsidiaries to purchasers of Clayton’s manufactured homes as well as those purchasing homes from selected independent retailers.

Clayton competes at the manufacturing, retail and finance levels on the basis of price, service, delivery capabilities and product performance and considers the ability to make financing available to retail purchasers a major factor affecting the market acceptance of its product.

UTLX Company (“UTLX”), headquartered in Chicago, Illinois, operates railcar, crane, intermodal tank container, manufacturing and service businesses under several brand names.

Railcars and intermodal tank containers are usually leased for multiple-year terms and most of the leases are renewed upon expiration. As a result of selective ongoing capital investment and high maintenance standards, utilization rates (the number of units on lease to total units available) of UTLX’s railcar, crane and intermodal tank container equipment remains relatively high over time. While tank cars operate in a highly regulated environment in North America, regulatory changes are not expected to materially impact UTLX’s operational capability, competitive position, or financial strength.

Therefore, as a provider of marginal capacity of transportation equipment, XTRA’s utilization rates and operating results tend to be cyclical. In addition, transportation providers often use leasing to maximize their asset utilization and reduce capital expenditures. By maintaining a large fleet, XTRA is able to provide customers with a broad selection of equipment and quick response times.
