The Exchange Offer

On January 5, 2018, we privately placed $2,200,000,000 aggregate principal amount of Initial Notes in a transaction exempt from registration under the Securities Act. In connection with the private placement, we entered into a registration rights agreement, dated as of January 5, 2018, with the initial purchasers of the Initial Notes. In the registration rights agreement, we agreed to offer the Exchange Notes, which will be registered under the Securities Act, in exchange for the applicable series of Initial Notes. The Exchange Offer described in this prospectus is intended to satisfy our obligations under the registration rights agreement. We also agreed to deliver this prospectus to the holders of the Initial Notes. You should read the discussion under the headings “Summary—Terms of the Notes” and “Description of the Notes” for information regarding the Notes.

The Exchange Offer This is an offer to exchange (i) $1,000 in principal amount of the 2021 Exchange Notes for each $1,000 in principal amount of the 2021 Initial Notes, (ii) $1,000 in principal amount of the 2023 Exchange Notes for each $1,000 in principal amount of the 2023 Initial Notes, (iii) $1,000 in principal amount of the 2028 Exchange Notes for each $1,000 in principal amount of the 2028 Initial Notes and (iv) $1,000 in principal amount of the 2048 Exchange Notes for each $1,000 in principal amount of the 2048 Initial Notes. The Exchange Notes are substantially identical to the Initial Notes, except that the Exchange Notes will generally be freely transferable. We believe that you can transfer the Exchange Notes without complying with the registration and prospectus delivery provisions of the Securities Act if you:

• acquire the Exchange Notes in the ordinary course of your business;

2

• are not, and do not intend to become, engaged in a distribution of the Exchange Notes;

• are not an “affiliate” (within the meaning of the Securities Act) of ours;

• are not a broker-dealer (within the meaning of the Securities Act) that acquired the Initial Notes from us or our affiliates; and

• are not a broker-dealer (within the meaning of the Securities Act) that acquired the Initial Notes in a transaction as part of its market-making or other trading activities.

If you do not meet these requirements, your resale of Exchange Notes must comply with the registration and prospectus delivery requirements of the Securities Act.

Our belief is based on interpretations by the staff of the SEC, as set forth inno-action letters issued to third parties. The staff of the SEC has not considered this Exchange Offer in the context of ano-action letter, and we cannot assure you that the staff of the SEC would make a similar determination with respect to this Exchange Offer.

If our belief is not accurate and you transfer an Exchange Note without delivering a prospectus meeting the requirements of the federal securities laws or without an exemption from these laws, you may incur liability under the federal securities laws. We do not and will not assume, or indemnify you against, this liability. See “The Exchange Offer—Terms of the Exchange.”

Registration Rights Agreement We have agreed to file an exchange offer registration statement or, under certain circumstances, a shelf registration statement pursuant to a registration rights agreement with respect to the Notes. The registration statement relating to the Exchange Offer described in this prospectus is intended to satisfy our obligations under the registration rights agreement with respect to such exchange offer registration statement.

Minimum Condition The Exchange Offer is not conditioned on any minimum aggregate principal amount of Initial Notes being tendered for exchange.

Expiration Date The Exchange Offer will expire at 5:00 p.m., New York City time, on May 2, 2018, unless we extend it.

Exchange Date The Initial Notes will be accepted for exchange at the time when all conditions of the Exchange Offer are satisfied or waived. The Exchange Notes will be issued and delivered promptly after the expiration of the Exchange Offer.

Conditions to the Exchange Our obligation to complete the Exchange Offer is subject to certain conditions. See “The Exchange Offer—Conditions to the Exchange

3

Offer.” We reserve the right to terminate the Exchange Offer if any such conditions shall have occurred or to amend the terms of the Exchange Offer in accordance with applicable law or regulation, in each case at any time prior to the expiration of the Exchange Offer on the expiration date.

Withdrawal Rights You may withdraw the tender of your Initial Notes at any time before the expiration of the Exchange Offer on the expiration date. Any Initial Notes not accepted for any reason will be returned to you without expense as promptly as practicable after the expiration or termination of the Exchange Offer.

Procedures for Tendering Initial Notes See “The Exchange Offer—How to Tender.”

U.S. Federal Income Tax Considerations The exchange of the Initial Notes for the Exchange Notes is not expected to be a taxable exchange for U.S. federal income tax purposes, and holders are not expected to realize any taxable gain or loss as a result of such exchange. For additional information, see “Certain U.S. Federal Income Tax Considerations.” You should consult your own tax advisor as to the tax consequences to you of the Exchange Offer, as well as tax consequences of the ownership and disposition of the Exchange Notes.

Effect on Holders of Initial Notes If the Exchange Offer is completed on the terms and within the period contemplated by this prospectus, holders of the Initial Notes will have no further registration or other rights under the registration rights agreement, except under limited circumstances. See “The Exchange Offer—Other.”

Holders of Initial Notes who do not tender their Initial Notes will continue to hold those Initial Notes. All untendered, and tendered but unaccepted, Initial Notes will continue to be subject to the transfer restrictions provided for in the Initial Notes and the indenture under which the Initial Notes have been issued. To the extent that the Initial Notes are tendered and accepted in the Exchange Offer, the trading market, if any, for the Initial Notes could be adversely affected. See “Risk Factors—Other Risks Associated with the Notes.” You may not be able to sell your Initial Notes if you do not exchange them for registered Exchange Notes in the Exchange Offer. Your ability to sell your Initial Notes may be significantly more limited and the price at which you may be able to sell your Initial Notes may be significantly lower if you do not exchange them for registered Exchange Notes in the Exchange Offer. See “The Exchange Offer—Other.”

Use of Proceeds We will not receive any proceeds from the issuance of Exchange Notes in the Exchange Offer.

Exchange Agent The Bank of New York Mellon Trust Company, N.A. is serving as the exchange agent in connection with the Exchange Offer.

Interest on Initial Notes Exchanged in the Exchange Offer For each series of Exchange Notes offered hereby, holders of such Exchange Notes on the record date for the first interest payment date following the consummation of the Exchange Offer will be entitled to receive interest accruing from the issue date of the Initial Notes or, if interest has been paid, the most recent date to which interest has been paid on the Initial Notes.

Risk Factors

This investment involves risks. Before you invest in the Notes, you should carefully consider the matters set forth under the heading “Risk Factors” on the next page and all other information in this prospectus.

7

RISK FACTORS

An investment in the Notes is subject to numerous risks and uncertainties, including, but not limited to, those described below. Careful consideration of these risks, together with all of the other information contained elsewhere in this prospectus and the documents incorporated by reference herein, should be made before making an investment decision. Additional risks and uncertainties not presently known or which we currently deem immaterial may also impair our business operations and our ability to service the Notes.

Our Corporate and Financial Structure Risks

We are a holding company and depend on distributions from subsidiaries, including joint ventures, to meet our obligations.

We are a holding company with no material assets other than the ownership interests in our subsidiaries and joint ventures, collectively referred to as our subsidiaries. Accordingly, cash flows and the ability to meet our obligations, including payment of principal, interest and any premium payments on the Notes, are largely dependent upon the earnings of our subsidiaries and the payment of such earnings to us in the form of dividends or other distributions. Our subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to pay amounts due pursuant to the Notes or our other obligations, or to make funds available, whether by dividends or other payments, for the payment of amounts due pursuant to our Notes or our other obligations, and do not guarantee the payment of any of our obligations, including the Notes. Distributions from subsidiaries may also be limited by:

• their respective earnings, capital requirements, and required debt and preferred stock payments;

• the satisfaction of certain terms contained in financing, ring-fencing or organizational documents; and

• regulatory restrictions that limit the ability of our regulated utility subsidiaries to distribute profits.

We are substantially leveraged, the terms of the Notes and our existing senior and junior subordinated debt do not (and the terms of our future debt are not expected to) restrict the incurrence of additional debt by us or our subsidiaries, and our senior debt, including the Notes, will be structurally subordinated to the debt of our subsidiaries, and each of such factors could adversely affect our consolidated financial results and our ability to service the Notes.

A significant portion of our capital structure is comprised of debt, and we expect to incur additional debt in the future to fund items such as, among others, acquisitions, capital investments and the development and construction of new or expanded facilities. As of December 31, 2017, we had the following outstanding obligations:

• senior unsecured debt of $6.5 billion;

• junior subordinated debentures of $100 million;

• short-term borrowings of $3.3 billion;

• guarantees and letters of credit in respect of subsidiary and equity method investments aggregating $332 million; and

• commitments, subject to satisfaction of certain specified conditions, to provide equity contributions in support of renewable tax equity investments totaling $265 million.

The above amounts do not include the $2.2 billion of Initial Notes issued on January 5, 2018.

Our consolidated subsidiaries also have significant amounts of outstanding debt, which totaled $29.8 billion as of December 31, 2017. These amounts exclude (a) trade debt, (b) preferred stock obligations, (c) letters of credit in respect of subsidiary debt, and (d) our share of the outstanding debt of our own or our subsidiaries’ equity method investments.

8

Given our substantial leverage, we may not have sufficient cash to service our debt, including the Notes, which could limit our ability to finance future acquisitions, develop and construct additional projects, or operate successfully under difficult conditions, including those brought on by adverse national and global economies, unfavorable financial markets or growth conditions where our capital needs may exceed our ability to fund them. Our leverage could also impair our credit quality or the credit quality of our subsidiaries, making it more difficult to finance operations or issue future debt on favorable terms, and could result in a downgrade in debt ratings, including those of the Notes, by credit rating agencies.

The terms of the Notes and our other senior debt do not limit our ability or the ability of our subsidiaries to incur additional debt or issue preferred stock. Accordingly, we or our subsidiaries could enter into acquisitions, new financings, refinancings, recapitalizations, capital leases or other highly leveraged transactions that could significantly increase our or our subsidiaries’ total amount of outstanding debt. The interest payments needed to service this increased level of debt could adversely affect our consolidated financial results and our ability to service the Notes. Many of our subsidiaries’ debt agreements contain covenants, or may in the future contain covenants, that restrict or limit, among other things, such subsidiaries’ ability to create liens, sell assets, make certain distributions, incur additional debt or miss contractual deadlines or requirements, and our ability to comply with these covenants may be affected by events beyond our control. Further, if an event of default accelerates a repayment obligation and such acceleration results in an event of default under some or all of our other debt or the indenture for the Notes, we may not have sufficient funds to repay all of the accelerated debt and the Notes simultaneously, and the other risks described under “Our Corporate and Financial Structure Risks” may be magnified as well.

Because we are a holding company, the claims of our senior debt holders are structurally subordinated with respect to the assets and earnings of our subsidiaries. Therefore, your rights and the rights of our other creditors to participate in the assets of any subsidiary in the event of a liquidation or reorganization are subject to the prior claims of the subsidiary’s creditors and preferred shareholders, if any. In addition, pursuant to separate financing agreements, substantially all of PacifiCorp’s electric utility properties, MidAmerican Energy’s electric utility properties in the state of Iowa, Nevada Power’s and Sierra Pacific’s properties in the state of Nevada, AltaLink’s transmission properties, the equity interest of MidAmerican Funding’s subsidiary and substantially all of the assets of the subsidiaries of BHE Renewables that are direct or indirect owners of solar and wind generation projects, are directly or indirectly pledged to secure their financings and, therefore, may be unavailable as potential sources of repayment of the Notes and our other senior debt.

A downgrade in our credit ratings or the credit ratings of our subsidiaries could negatively affect our or our subsidiaries’ access to capital, increase the cost of borrowing or raise energy transaction credit support requirements.

Our senior unsecured debt and our subsidiaries’ long-term debt are rated by various rating agencies. We cannot give assurance that our senior unsecured debt rating or any of our subsidiaries’ long-term debt ratings will not be reduced in the future. Although none of our outstanding debt has rating-downgrade triggers that would accelerate a repayment obligation, a credit rating downgrade would increase our borrowing costs and commitment fees on our revolving credit agreements and other financing arrangements, perhaps significantly. In addition, we would likely be required to pay a higher interest rate in future financings, and the potential pool of investors and funding sources would likely decrease. Further, access to the commercial paper market, our principal source of short-term borrowings, could be significantly limited, resulting in higher interest costs.

Similarly, any downgrade or other event negatively affecting the credit ratings of our subsidiaries could make their costs of borrowing higher or access to funding sources more limited, which in turn could cause us to provide liquidity in the form of capital contributions or loans to such subsidiaries, thus reducing our and our subsidiaries’ liquidity and borrowing capacity.

Most of our subsidiaries’ large wholesale customers, suppliers and counterparties require our subsidiaries to have sufficient creditworthiness in order to enter into transactions, particularly in the wholesale energy markets.

9

If the credit ratings of our subsidiary or subsidiaries were to decline, especially below investment grade, such subsidiary or subsidiaries’ financing costs and borrowings would likely increase because certain counterparties may require collateral in the form of cash, a letter of credit or some other form of security for existing transactions and as a condition to entering into future transactions with such subsidiary or subsidiaries. Amounts may be material and may adversely affect such subsidiary or subsidiaries’ liquidity and cash flows.

Our majority shareholder, Berkshire Hathaway, could exercise control over us in a manner that would benefit Berkshire Hathaway to the detriment of our creditors.

Berkshire Hathaway is our majority owner and has control over all decisions requiring shareholder approval. In circumstances involving a conflict of interest between Berkshire Hathaway and our creditors, Berkshire Hathaway could exercise its control in a manner that would benefit Berkshire Hathaway to the detriment of our creditors.

Our Business Risks

Much of our growth has been achieved through acquisitions, and any such acquisition may not be successful.

Much of our growth has been achieved through acquisitions. Future acquisitions may range from buying individual assets to the purchase of entire businesses. We will continue to investigate and pursue opportunities for future acquisitions that we believe, but cannot assure you, may increase value and expand or complement existing businesses. We may participate in bidding or other negotiations at any time for such acquisition opportunities which may or may not be successful.

Any acquisition entails numerous risks, including, among others:

• the failure to complete the transaction for various reasons, such as the inability to obtain the required regulatory approvals, materially adverse developments in the potential acquiree’s business or financial condition or successful intervening offers by third parties;

• the failure of the combined business to realize the expected benefits;

• the risk that federal, state or foreign regulators or courts could require regulatory commitments or other actions in respect of acquired assets, potentially including programs, contributions, investments, divestitures and market mitigation measures;

• the risk of unexpected or unidentified issues not discovered in the diligence process; and

• the need for substantial additional capital and financial investments.

An acquisition could cause an interruption of, or a loss of momentum in, the activities of one or more of our subsidiaries. In addition, the final orders of regulatory authorities approving acquisitions may be subject to appeal by third parties. The diversion of our management’s attention and any delays or difficulties encountered in connection with the approval and integration of the acquired operations could adversely affect our combined businesses and financial results and could impair our ability to realize the anticipated benefits of the acquisition.

We cannot assure you that future acquisitions, if any, or any integration efforts will be successful, or that our ability to repay our obligations, including the Notes, will not be adversely affected by any future acquisitions.

Our subsidiaries are subject to operating uncertainties and events beyond our and our subsidiaries’ control that impact the costs to operate, maintain, repair and replace utility and interstate natural gas pipeline systems, which could adversely affect our consolidated financial results and our ability to service the Notes.

The operation of complex utility systems or interstate natural gas pipeline and storage systems that are spread over large geographic areas involves many operating uncertainties and events beyond our and our

10

subsidiaries’ control. These potential events include the breakdown or failure of our thermal, nuclear, hydroelectric, solar, wind and other electricity generating facilities and related equipment, compressors, pipelines, transmission and distribution lines or other equipment or processes, which could lead to catastrophic events; unscheduled outages; strikes, lockouts or other labor-related actions; shortages of qualified labor; transmission and distribution system constraints; failure to obtain, renew or maintainrights-of-way, easements and leases on United States federal, Native American, First Nations or tribal lands; terrorist activities or military or other actions, including cyber attacks; fuel shortages or interruptions; unavailability of critical equipment, materials and supplies; low water flows and other weather-related impacts; performance below expected levels of output, capacity or efficiency; operator error; third party excavation errors; unexpected degradation of pipeline systems; design, construction or manufacturing defects; and catastrophic events such as severe storms, floods, fires, earthquakes, explosions, landslides, an electromagnetic pulse, mining incidents, litigation, wars, terrorism and embargoes. A catastrophic event might result in injury or loss of life, extensive property damage or environmental or natural resource damages.

For example, in the event of an uncontrolled release of water at one of PacifiCorp’s high hazard potential hydroelectric dams, it is probable that loss of human life, disruption of lifeline facilities and property damage could occur in the downstream population and civil or other penalties could be imposed by the Federal Energy Regulatory Commission (“FERC”). Any of these events or other operational events could significantly reduce or eliminate our subsidiaries’ revenue or significantly increase their expenses, thereby reducing the availability of distributions to us For example, if our subsidiaries cannot operate their electricity or natural gas facilities at full capacity due to damage caused by a catastrophic event, their revenue could decrease and their expenses could increase due to the need to obtain energy from more expensive sources. Further, we and our subsidiaries self-insure many risks, and current and future insurance coverage may not be sufficient to replace lost revenue or cover repair and replacement costs. The scope, cost and availability of our and our subsidiaries’ insurance coverage may change, including the portion that is self-insured. Any reduction of our subsidiaries’ revenue or increase in their expenses resulting from the risks described above, could adversely affect our consolidated financial results and our ability to service the Notes.

We and our subsidiaries are subject to extensive federal, state, local and foreign legislation and regulation, including numerous environmental, health, safety, reliability and other laws and regulations that affect us and our subsidiaries’ operations and costs. These laws and regulations are complex, dynamic and subject to new interpretations or change. In addition, new laws and regulations, including initiatives regarding deregulation and restructuring of the utility industry, are continually being proposed and enacted that impose new or revised requirements or standards on us and our subsidiaries.

We and our subsidiaries are required to comply with numerous federal, state, local and foreign laws and regulations that have broad application to us and our subsidiaries and limit our and our subsidiaries’ ability to independently make and implement management decisions regarding, among other items, acquiring businesses; constructing, acquiring or disposing of operating assets; operating and maintaining generating facilities and transmission and distribution system assets; complying with pipeline safety and integrity and environmental requirements; setting rates charged to customers; establishing capital structures and issuing debt or equity securities; transacting between subsidiaries and affiliates; and paying dividends or similar distributions. These laws and regulations, which are followed in developing our and our subsidiaries’ safety and compliance programs and procedures, are implemented and enforced by federal, state and local regulatory agencies, such as the Occupational Safety and Health Administration, the FERC, the Environmental Protection Agency, the Department of Transportation, the Nuclear Regulatory Commission (“NRC”), the Federal Mine Safety and Health Administration and various state regulatory commissions in the United States, and foreign regulatory agencies, such as the Gas and Electricity Markets Authority (“GEMA”), which discharges certain of its powers through its staff within its office of gas and electric markets (known as “Ofgem”), in Great Britain and the Alberta Utilities Commission (“AUC”) in Alberta, Canada.

Compliance with applicable laws and regulations generally requires our subsidiaries to obtain and comply with a wide variety of licenses, permits, inspections, audits and other approvals. Further, compliance with laws

11

and regulations can require significant capital and operating expenditures, including expenditures for new equipment, inspection, cleanup costs, removal and remediation costs and damages arising out of contaminated properties. Compliance activities pursuant to existing or new laws and regulations could be prohibitively expensive or otherwise uneconomical. As a result, our subsidiaries could be required to shut down some facilities or materially alter their operations. Further, our subsidiaries may not be able to obtain or maintain all required environmental or other regulatory approvals and permits for their operating assets or development projects. Delays in, or active opposition by third parties to, obtaining any required environmental or regulatory authorizations or failure to comply with the terms and conditions of the authorizations may increase costs or prevent or delay our subsidiaries from operating their facilities, developing or favorably locating new facilities or expanding existing facilities. If our subsidiaries fail to comply with any environmental or other regulatory requirements, they may be subject to penalties and fines or other sanctions, including changes to the way its electricity generating facilities are operated that may adversely impact generation or how Northern Natural Gas Company and Kern River (the “Pipeline Companies”) are permitted to operate their systems that may adversely impact throughput. The costs of complying with laws and regulations could adversely affect our consolidated financial results and our ability to service the Notes. Not being able to operate existing facilities or develop new generating facilities to meet customer electricity needs could require our subsidiaries to increase their purchases of electricity on the wholesale market, which could increase market and price risks and adversely affect our consolidated financial results and our ability to service the Notes.

Existing laws and regulations, while comprehensive, are subject to changes and revisions from ongoing policy initiatives by legislators and regulators and to interpretations that may ultimately be resolved by the courts. For example, changes in laws and regulations could result in, but are not limited to, increased competition and decreased revenues within our subsidiaries’ service territories, such as the Nevada Energy Choice Initiative; new environmental requirements, including the implementation of or changes to the Clean Power Plan, renewable portfolio standards and greenhouse gas emissions reduction goals; the issuance of new or stricter air quality standards; the implementation of energy efficiency mandates; the issuance of regulations governing the management and disposal of coal combustion byproducts; changes in forecasting requirements; changes to our subsidiaries’ service territories as a result of condemnation or takeover by municipalities or other governmental entities, particularly where they lack the exclusive right to serve their customers; the inability of our subsidiaries to recover their costs on a timely basis, if at all; new pipeline safety requirements; or a negative impact on our subsidiaries’ current transportation and cost recovery arrangements. In addition to changes in existing legislation and regulation, new laws and regulations are likely to be enacted from time to time that impose additional or new requirements or standards on our subsidiaries.

Implementing actions required under, and otherwise complying with, new federal and state laws and regulations and changes in existing ones are among the most challenging aspects of managing utility operations. We cannot accurately predict the type or scope of future laws and regulations that may be enacted, changes in existing ones or new interpretations by agency orders or court decisions nor can we determine their impact on us at this time; however, any one of these could adversely affect our consolidated financial results and our ability to service the Notes through higher capital expenditures and operating costs and early closure of generating facilities or restrict or otherwise cause an adverse change in how we operate our businesses. To the extent that our regulated subsidiaries are not allowed by their regulators to recover or cannot otherwise recover the costs to comply with new laws and regulations or changes in existing ones, the costs of complying with such additional requirements could have a material adverse effect on our consolidated financial results and our ability to service the Notes. Additionally, even if such costs are recoverable in rates, if they are substantial and result in rates increasing to levels that substantially reduce customer demand, this could have a material adverse effect on our consolidated financial results and our ability to service the Notes. We have made our best estimate regarding the impact of the Tax Cuts and Jobs Act enacted in December 2017 (“2017 Tax Reform”) and the probability and timing of settlements of net regulatory liabilities established pursuant to the 2017 Tax Reform. However, the amount and timing of the settlements may change based on decisions and actions by each of our regulators, which could have an effect on our consolidated financial results and our ability to service the Notes.

12

Recovery of costs and certain activities by our subsidiaries is subject to regulatory review and approval, and the inability to recover costs or undertake certain activities may adversely affect our consolidated financial results and our ability to service the Notes.

State Regulatory Rate Review Proceedings

PacifiCorp, MidAmerican Energy, Nevada Power and Sierra Pacific (collectively, the “Utilities”) establish rates for their regulated retail service through state regulatory proceedings. These proceedings typically involve multiple parties, including government bodies and officials, consumer advocacy groups and various consumers of energy, who have differing concerns but generally have the common objective of limiting rate increases while also requiring the Utilities to ensure system reliability. Decisions are subject to judicial appeal, potentially leading to further uncertainty associated with the approval proceedings.

States set retail rates based in part upon the state regulatory commission’s acceptance of an allocated share of total utility costs. When states adopt different methods to calculate interjurisdictional cost allocations, some costs may not be incorporated into rates of any state or other jurisdiction. Ratemaking is also generally done on the basis of estimates of normalized costs, so if a given year’s realized costs are higher than normalized costs, rates may not be sufficient to cover those costs. In some cases, actual costs are lower than the normalized or estimated costs recovered through rates and fromtime-to-time may result in a state regulator requiring refunds to customers. Each state regulatory commission generally sets rates based on a test year established in accordance with that commission’s policies. The test year data adopted by each state regulatory commission may create a lag between the incurrence of a cost and its recovery in rates. Each state regulatory commission also decides the allowed levels of expense, investment and capital structure that it deems are just and reasonable in providing the service and may disallow recovery in rates for any costs that it believes do not meet such standard. Additionally, each state regulatory commission establishes the allowed rate of return the Utilities will be given an opportunity to earn on their sources of capital. While rate regulation is premised on providing a fair opportunity to earn a reasonable rate of return on invested capital, the state regulatory commissions do not guarantee that we will be able to realize the allowed rate of return.

Energy cost increases above the level assumed in establishing base rates may be subject to customer sharing. Any significant increase in fuel costs for electricity generation or purchased electricity costs could have a negative impact on the Utilities, despite efforts to minimize this impact through the use of hedging contracts and sharing mechanisms or through future general regulatory rate reviews. Any of these consequences could adversely affect our consolidated financial results and our ability to service the Notes.

FERC Jurisdiction

The FERC authorizes cost-based rates associated with transmission services provided by the Utilities’ transmission facilities. Under the Federal Power Act, the Utilities, or Midcontinent Independent System Operator, Inc. (“MISO”) as it relates to MidAmerican Energy, may voluntarily file, or may be obligated to file, for changes, including general rate changes, to their system-wide transmission service rates. General rate changes implemented may be subject to refund. The FERC also has responsibility for approving both cost- and market-based rates under which the Utilities sell electricity at wholesale, has jurisdiction over most of PacifiCorp’s hydroelectric generating facilities and has broad jurisdiction over energy markets. The FERC may impose price limitations, bidding rules and other mechanisms to address some of the volatility of these markets or could revoke or restrict the ability of the Utilities to sell electricity at market-based rates, which could adversely affect our consolidated financial results and our ability to service the Notes. The FERC also maintains rules concerning standards of conduct, affiliate restrictions, interlocking directorates and cross-subsidization. As a transmission owning member of MISO, MidAmerican Energy is also subject to MISO-directed modifications of market rules, which are subject to FERC approval and operational procedures. As participants in the Energy Imbalance Market, PacifiCorp, Nevada Power and Sierra Pacific are also subject to applicable California Independent System Operator Corporation rules, which are subject to FERC approval and operational procedures. The FERC may also impose substantial civil penalties for anynon-compliance with the Federal Power Act and the FERC’s rules and orders.

13

The North American Electric Reliability Corporation (“NERC”) has standards in place to ensure the reliability of the electric generation system and transmission grid. The Utilities are subject to the NERC’s regulations and periodic audits to ensure compliance with those regulations. The NERC may carry out enforcement actions fornon-compliance and administer significant financial penalties, subject to the FERC’s review.

The FERC has jurisdiction over, among other things, the construction, abandonment, modification and operation of natural gas pipelines and related facilities used in the transportation, storage and sale of natural gas in interstate commerce, including all rates, charges and terms and conditions of service. The FERC also has market transparency authority and has adopted additional reporting and internet posting requirements for natural gas pipelines and buyers and sellers of natural gas.

Rates for the interstate natural gas transmission and storage operations at the Pipeline Companies, which include reservation, commodity, surcharges, fuel and gas lost and unaccounted for charges, are authorized by the FERC. In accordance with the FERC’s rate-making principles, the Pipeline Companies’ current maximum tariff rates are designed to recover prudently incurred costs included in their pipeline system’s regulatory cost of service that are associated with the construction, operation and maintenance of their pipeline system and to afford the Pipeline Companies an opportunity to earn a reasonable rate of return. Nevertheless, the rates the FERC authorizes the Pipeline Companies to charge their customers may not be sufficient to recover the costs incurred to provide services in any given period. Moreover, from time to time, the FERC may change, alter or refine its policies or methodologies for establishing pipeline rates and terms and conditions of service. In addition, the FERC has the authority under Section 5 of the Natural Gas Act of 1938 to investigate whether a pipeline may be earning more than its allowed rate of return and, when appropriate, to institute proceedings against such pipeline to prospectively reduce rates. Any such proceedings, if instituted, could result in significantly adverse rate decreases.

Under FERC policy, interstate pipelines and their customers may execute contracts at negotiated rates, which may be above or below the maximum tariff rate for that service or the pipeline may agree to provide a discounted rate, which would be a rate between the maximum and minimum tariff rates. In a rate proceeding, rates in these contracts are generally not subject to adjustment. It is possible that the cost to perform services under negotiated or discounted rate contracts will exceed the cost used in the determination of the negotiated or discounted rates, which could result either in losses or lower rates of return for providing such services. Under certain circumstances, FERC policy allows interstate natural gas pipelines to design new maximum tariff rates to recover such costs in regulatory rate reviews. However, with respect to discounts granted to affiliates, the interstate natural gas pipeline must demonstrate that the discounted rate was necessary in order to meet competition.

GEMA Jurisdiction

Northern Powergrid (Northeast) Limited and Northern Powergrid (Yorkshire) plc (collectively, the “Northern Powergrid Distribution Companies”), as Distribution Network Operators (“DNOs”) and holders of electricity distribution licenses, are subject to regulation by GEMA. Most of the revenue of a DNO is controlled by a distribution price control formula set out in the electricity distribution license. The price control formula does not directly constrain profits from year to year, but is a control on revenue that operates independently of a significant portion of the DNO’s actual costs. A resetting of the formula does not require the consent of the DNO, but if a licensee disagrees with a change to its license it can appeal the matter to the United Kingdom’s Competition and Markets Authority. GEMA is able to impose financial penalties on DNOs that contravene any of their electricity distribution license duties or certain of their duties under British law, or fail to achieve satisfactory performance of individual standards prescribed by GEMA. Any penalty imposed must be reasonable and may not exceed 10% of the DNO’s revenue. During the term of any price control, additional costs have a direct impact on the financial results of the Northern Powergrid Distribution Companies.

14

AUC Jurisdiction

The AUC is an independent, quasi-judicial agency established by the province of Alberta, Canada, which is responsible for, among other things, approving the tariffs of transmission facility owners, including AltaLink, L.P. (“ALP”), and distribution utilities, acquisitions of such transmission facility owners or utilities, and construction and operation of new transmission projects in Alberta. The AUC also investigates and rules on regulated rate disputes and system access problems.

The AUC regulates and oversees Alberta’s electricity transmission sector with broad authority that may impact many of ALP’s activities, including its tariffs, rates, construction, operations and financing. The AUC has various core functions in regulating the Alberta electricity transmission sector, including the following:

• regulating and adjudicating issues related to the operation of electric utilities within Alberta;

• processing and approving general tariff applications relating to revenue requirements and rates of return including deemed capital structure for regulated utilities while ensuring that utility rates are just and reasonable and approval of the transmission tariff rates of regulated transmission providers by the Alberta Electric System Operator (“AESO”), which is the independent transmission system operator in Alberta that controls the operation of AltaLink’s transmission system;

• approving the need for new electricity transmission facilities and permits to build and licenses to operate electricity transmission facilities;

• reviewing operations and accounts from electric utilities and conductingon-site inspections to ensure compliance with industry regulation and standards;

• adjudicating enforcement issues including the imposition of administrative penalties that arise when market participants violate the rules of the AESO; and

• collecting, storing, analyzing, appraising and disseminating information to effectively fulfill its duties as an industry regulator.

In addition, AUC approval is required in connection with new energy and regulated utility initiatives in Alberta, amendments to existing approvals and financing proposals by designated utilities.

The AESO determines the need and plans for the expansion and enhancement of a congestion free transmission system in Alberta in accordance with applicable law and reliability standards. The AESO’s responsibilities include long-term transmission planning and management, including assessing and planning for the current and future transmission system capacity needs of AESO market participants. When AESO determines an expansion or enhancement of the transmission system is needed, with limited exceptions, it submits an application to the AUC for approval of the proposed expansion or enhancement. The AESO then determines which transmission provider should submit an application to the AUC for a permit and license to construct and operate the designated transmission facilities. Generally the transmission provider operating in the geographic area where the transmission facilities expansion or enhancement is to be located is selected by the AESO to build, own and operate the transmission facilities. In addition, Alberta law provides that transmission projects may be subject to a competitive process open to qualifying bidders. In either case, there can be no assurance that any jurisdictional market participant that we may own, including AltaLink, will be selected by the AESO to build, own and operate transmission facilities, even if our market participant operates in the relevant geographic area, or that our market participant will be successful in any such competitive process in which it may participate.

Physical or cyber attacks, both threatened and actual, could impact our and our subsidiaries’ operations and could adversely affect our consolidated financial results and our ability to service the Notes.

We and our subsidiaries rely on information technology in virtually all aspects of our business. A significant disruption or failure of our information technology systems by physical or cyber attack could result in service

15

interruptions, safety failures, security violations, regulatory compliance failures, an inability to protect corporate information and assets against intruders, and other operational difficulties. Attacks perpetrated against our and our subsidiaries’ information systems could result in loss of assets and critical information and expose us and our subsidiaries to remediation costs and reputational damage.

Although we and our subsidiaries have taken steps intended to mitigate these risks, a significant disruption or cyber intrusion could lead to misappropriation of assets or data corruption. Cyber attacks could further adversely affect our and our subsidiaries’ abilities to operate facilities, information technology and business systems, or compromise sensitive customer and employee information. In addition, physical or cyber attacks against key suppliers or service providers could have a similar effect on us and our subsidiaries. Additionally, if we or our subsidiaries are unable to acquire or implement new technology, we or our subsidiaries may suffer a competitive disadvantage. Any of these items could adversely affect our results of operations, financial condition or liquidity or our ability to service the Notes.

Our subsidiaries are actively pursuing, developing and constructing new or expanded facilities, the completion and expected costs of which are subject to significant risk, and our subsidiaries have significant funding needs related to their planned capital expenditures.

Through our subsidiaries, we actively pursue, develop and construct new or expanded facilities. Our subsidiaries expect to incur significant annual capital expenditures over the next several years. Such expenditures may include construction and other costs for new electricity generating facilities, electric transmission or distribution projects, environmental control and compliance systems, natural gas storage facilities, new or expanded pipeline systems, and continued maintenance and upgrades of existing assets.

Development and construction of major facilities are subject to substantial risks, including fluctuations in the price and availability of commodities, manufactured goods, equipment, labor, siting and permitting and changes in environmental and operational compliance matters, load forecasts and other items over a multi-year construction period, as well as counterparty risk and the economic viability of our suppliers, customers and contractors. Certain of our construction projects are substantially dependent upon a single supplier or contractor and replacement of such supplier or contractor may be difficult and cannot be assured. These risks may result in the inability to timely complete a project or higher than expected costs to complete an asset and place itin-service and, in extreme cases, the loss of the power purchase agreements or other long-termoff-take contracts underlying such projects. Such costs may not be recoverable in the regulated rates or market or contract prices our subsidiaries are able to charge their customers. Delays in construction of renewable projects may result in delayedin-service dates which may result in the loss of anticipated revenue or income tax benefits. It is also possible that additional generation needs may be obtained through power purchase agreements, which could increase long-term purchase obligations and force reliance on the operating performance of a third party. The inability to successfully and timely complete a project, avoid unexpected costs or recover any such costs could adversely affect our consolidated financial results and our ability to service the Notes.

Furthermore, our subsidiaries depend upon both internal and external sources of liquidity to provide working capital and to fund capital requirements. If we do not provide needed funding to our subsidiaries and our subsidiaries are unable to obtain funding from external sources, they may need to postpone or cancel planned capital expenditures.

16

A significant sustained decrease in demand for electricity or natural gas in the markets served by our subsidiaries would decrease our operating revenue, could impact our planned capital expenditures and could adversely affect our consolidated financial results and our ability to service the Notes.

A significant sustained decrease in demand for electricity or natural gas in the markets served by our subsidiaries would decrease our operating revenue, could impact our planned capital expenditures and could adversely affect our consolidated financial results and our ability to service the Notes. Factors that could lead to a decrease in market demand include, among others:

• a depression, recession or other adverse economic condition that results in a lower level of economic activity or reduced spending by consumers on electricity or natural gas;

• an increase in the market price of electricity or natural gas or a decrease in the price of other competing forms of energy;

• shifts in competitively priced natural gas supply sources away from the sources connected to the Pipeline Companies’ systems, including shale gas sources;

• efforts by customers, legislators and regulators to reduce the consumption of electricity generated or distributed by our subsidiaries through various existing laws and regulations, as well as, deregulation, conservation, energy efficiency and private generation measures and programs;

• laws mandating or encouraging renewable energy sources, which may decrease the demand for electricity and natural gas or change the market prices of these commodities;

• higher fuel taxes or other governmental or regulatory actions that increase, directly or indirectly, the cost of natural gas or other fuel sources for electricity generation or that limit the use of natural gas or the generation of electricity from fossil fuels;

• a shift to more energy-efficient or alternative fuel machinery or an improvement in fuel economy, whether as a result of technological advances by manufacturers, legislation mandating higher fuel economy or lower emissions, price differentials, incentives or otherwise;

• a reduction in the state or federal subsidies or tax incentives that are provided to agricultural, industrial or other customers, or a significant sustained change in prices for commodities such as ethanol or corn for ethanol manufacturers; and

• sustained mild weather that reduces heating or cooling needs.

Our subsidiaries’ operating results may fluctuate on a seasonal and quarterly basis and may be adversely affected by weather.

In most parts of the United States and other markets in which our subsidiaries operate, demand for electricity peaks during the summer months when irrigation and cooling needs are higher. Market prices for electricity also generally peak at that time. In other areas, demand for electricity peaks during the winter when heating needs are higher. In addition, demand for natural gas and other fuels generally peaks during the winter. This is especially true in MidAmerican Energy’s and Sierra Pacific’s retail natural gas businesses. Further, extreme weather conditions, such as heat waves, winter storms or floods could cause these seasonal fluctuations to be more pronounced. Periods of low rainfall or snowpack may negatively impact electricity generation at PacifiCorp’s hydroelectric generating facilities, which may result in greater purchases of electricity from the wholesale market or from other sources at market prices. Additionally, PacifiCorp and MidAmerican Energy have added substantial wind-powered generating capacity, and our unregulated subsidiaries are adding solar and wind-powered generating capacity, each of which is also a climate-dependent resource.

As a result, the overall financial results of our subsidiaries may fluctuate substantially on a seasonal and quarterly basis. We have historically provided less service, and consequently earned less income, when weather conditions are mild. Unusually mild weather in the future may adversely affect our consolidated financial results and our ability to service the Notes through lower revenue or margins. Conversely, unusually extreme weather

17

conditions could increase our costs to provide services and could adversely affect our consolidated financial results and our ability to service the Notes. The extent of fluctuation in our consolidated financial results may change depending on a number of factors related to our subsidiaries’ regulatory environment and contractual agreements, including their ability to recover energy costs, the existence of revenue sharing provisions as it relates to MidAmerican Energy, and terms of the wholesale sale contracts.

Our subsidiaries are subject to market risk associated with the wholesale energy markets, which could adversely affect our consolidated financial results and our ability to service the Notes.

In general, our primary market risk is adverse fluctuations in the market price of wholesale electricity and fuel, including natural gas, coal and fuel oil, which is compounded by volumetric changes affecting the availability of or demand for electricity and fuel. The market price of wholesale electricity may be influenced by several factors, such as the adequacy or type of generating capacity, scheduled and unscheduled outages of generating facilities, prices and availability of fuel sources for generation, disruptions or constraints to transmission and distribution facilities, weather conditions, demand for electricity, economic growth and changes in technology. Volumetric changes are caused by fluctuations in generation or changes in customer needs that can be due to the weather, electricity and fuel prices, the economy, regulations or customer behavior. For example, the Utilities purchase electricity and fuel in the open market as part of their normal operating businesses. If market prices rise, especially in a time when larger than expected volumes must be purchased at market prices, the Utilities may incur significantly greater expense than anticipated. Likewise, if electricity market prices decline in a period when the Utilities are a net seller of electricity in the wholesale market, the Utilities could earn less revenue. Although the Utilities have energy cost adjustment mechanisms, the risks associated with changes in market prices may not be fully mitigated due to customer sharing bands as it relates to PacifiCorp and other factors.

Potential terrorist activities and the impact of military or other actions, could adversely affect our consolidated financial results and our ability to service the Notes.

The ongoing threat of terrorism and the impact of military or other actions by nations or politically, ethnically or religiously motivated organizations regionally or globally may create increased political, economic, social and financial market instability, which could subject our subsidiaries’ operations to increased risks. Additionally, the United States government has issued warnings that energy assets, specifically pipeline, nuclear generation, transmission and other electric utility infrastructure, are potential targets for terrorist attacks.

Political, economic, social or financial market instability or damage to or interference with the operating assets of our subsidiaries, customers or suppliers may result in business interruptions, lost revenue, higher commodity prices, disruption in fuel supplies, lower energy consumption and unstable markets, particularly with respect to electricity and natural gas, and increased security, repair or other costs, any of which may materially adversely affect us and our subsidiaries in ways that cannot be predicted at this time. Any of these risks could materially affect our consolidated financial results and our ability to service the Notes. Furthermore, instability in the financial markets as a result of terrorism or war could also materially adversely affect our and our subsidiaries’ ability to raise capital.

Certain of our subsidiaries are subject to the unique risks associated with nuclear generation.

The ownership and operation of nuclear power plants, such as MidAmerican Energy’s 25% ownership interest in Quad Cities Station, involves certain risks. These risks include, among other items, mechanical or structural problems, inadequacy or lapses in maintenance protocols, the impairment of reactor operation and safety systems due to human error, the costs of storage, handling and disposal of nuclear materials, compliance with and changes in regulation of nuclear power plants, limitations on the amounts and types of insurance coverage commercially available, and uncertainties with respect to the technological and financial aspects of decommissioning nuclear facilities at the end of their useful lives. Additionally, Exelon Generation Company,

18

LLC, the 75% owner and operator of the facility, may respond to the occurrence of any of these or other risks in a manner that negatively impacts MidAmerican Energy, including closure of Quad Cities Station prior to the expiration of its operating license. The prolonged unavailability, or early closure, of Quad Cities Station due to operational or economic factors could have a materially adverse effect on MidAmerican Energy’s financial results and our ability to service the Notes, particularly when the cost to produce power at the plant is significantly less than market wholesale prices. The following are among the more significant of these risks:

• Operational Risk—Operations at any nuclear power plant could degrade to the point where the plant would have to be shut down. If such degradations were to occur, the process of identifying and correcting the causes of the operational downgrade to return the plant to operation could require significant time and expense, resulting in both lost revenue and increased fuel and purchased electricity costs to meet supply commitments. Rather than incurring substantial costs to restart the plant, the plant could be shut down. Furthermore, a shut-down or failure at any other nuclear power plant could cause regulators to require a shut-down or reduced availability at Quad Cities Station. In addition, issues relating to the disposal of nuclear waste material, including the availability, unavailability and expense of a permanent repository for spent nuclear fuel could adversely impact operations as well as the cost and ability to decommission nuclear power plants, including Quad Cities Station, in the future.

• Regulatory Risk—The NRC may modify, suspend or revoke licenses and impose civil penalties for failure to comply with applicable Atomic Energy Act regulations or the terms of the licenses of nuclear facilities. Unless extended, the NRC operating licenses for Quad Cities Station will expire in 2032. Changes in regulations by the NRC could require a substantial increase in capital expenditures or result in increased operating or decommissioning costs.

• Nuclear Accident and Catastrophic Risks—Accidents and other unforeseen catastrophic events have occurred at nuclear facilities other than Quad Cities Station, both in the United States and elsewhere, such as at the Fukushima Daiichi nuclear power plant in Japan as a result of the earthquake and tsunami in March 2011. The consequences of an accident or catastrophic event can be severe and include loss of life and property damage. Any resulting liability from a nuclear accident or catastrophic event could exceed our or the relevant subsidiary’s resources, including insurance coverage.

Certain of our subsidiaries are subject to the risk that customers will not renew their contracts or that our subsidiaries will be unable to obtain new customers for expanded capacity, each of which could adversely affect our consolidated financial results and our ability to service the Notes.

If our subsidiaries are unable to renew, remarket, or find replacements for their customer agreements on favorable terms, our sales volumes and operating revenue would be exposed to reduction and increased volatility. For example, without the benefit of long-term transportation agreements, we cannot assure that the Pipeline Companies will be able to transport natural gas at efficient capacity levels. Substantially all of the Pipeline Companies’ revenues are generated under transportation and storage contracts that periodically must be renegotiated and extended or replaced, and the Pipeline Companies are dependent upon relatively few customers for a substantial portion of their revenue. Similarly, without long-term power purchase agreements, we cannot assure that our unregulated power generators will be able to operate profitably. Failure to maintain existing long- term agreements or secure new long-term agreements, or being required to discount rates significantly upon renewal or replacement, could adversely affect our consolidated financial results and our ability to service the Notes. The replacement of any existing long-term agreements depends on market conditions and other factors that may be beyond our subsidiaries’ control.

Our subsidiaries are subject to counterparty risk, which could adversely affect our consolidated financial results and our ability to service the Notes.

Our subsidiaries are subject to counterparty credit risk related to contractual payment obligations with wholesale suppliers and customers. Adverse economic conditions or other events affecting counterparties with whom our subsidiaries conduct business could impair the ability of these counterparties to meet their payment

19

obligations. Our subsidiaries depend on these counterparties to remit payments on a timely basis. We continue to monitor the creditworthiness of our wholesale suppliers and customers in an attempt to reduce the impact of any potential counterparty default. If strategies used to minimize these risk exposures are ineffective or if any of our subsidiaries’ wholesale suppliers’ or customers’ financial condition deteriorates or they otherwise become unable to pay, it could have a significant adverse impact on our liquidity, our consolidated financial results and our ability to service the Notes.

Our subsidiaries are subject to counterparty performance risk related to performance of contractual obligations by wholesale suppliers, customers and contractors. We rely on wholesale suppliers to deliver commodities, primarily natural gas, coal and electricity, in accordance with short- and long-term contracts. Failure or delay by suppliers to provide these commodities pursuant to existing contracts could disrupt the delivery of electricity and require the Utilities to incur additional expenses to meet customer needs. In addition, when these contracts terminate, the Utilities may be unable to purchase the commodities on terms equivalent to the terms of current contracts.

Our subsidiaries rely on wholesale customers to take delivery of the energy they have committed to purchase. Failure of customers to take delivery may require these subsidiaries to find other customers to take the energy at lower prices than the original customers committed to pay. If our subsidiaries’ wholesale customers are unable to fulfill their obligations, there may be a significant adverse impact on our consolidated financial results and our ability to service the Notes.

The Northern Powergrid Distribution Companies�� customers are concentrated in a small number of electricity supply businesses with RWE Npower PLC and British Gas Trading Limited accounting for approximately 21% and 15%, respectively, of distribution revenue in 2017. AltaLink’s primary source of operating revenue is the AESO. Generally, a single customer purchases the energy from our independent power projects in the United States and the Philippines pursuant to long-term power purchase agreements. Any material performance failure by the counterparties in these arrangements could have a significant adverse impact on our consolidated financial results and our ability to service the Notes.

We and our subsidiaries own investments and projects in foreign countries that are exposed to risks related to fluctuations in foreign currency exchange rates and increased economic, regulatory and political risks.

Our and our subsidiaries’ business operations and investments outside the United States increase our risk related to fluctuations in foreign currency exchange rates, primarily the British pound and the Canadian dollar. Our principal reporting currency is the United States dollar, and the value of the assets and liabilities, earnings, cash flows and potential distributions from our foreign operations changes with the fluctuations of the currency in which they transact. We indirectly own a hydroelectric power plant in the Philippines and may acquire significant energy-related investments and projects outside of the United States. We may selectively reduce some foreign currency exchange rate risk by, among other things, requiring contracted amounts be settled in, or indexed to, United States dollars or a currency freely convertible into United States dollars, or hedging through foreign currency derivatives. These efforts, however, may not be effective and could negatively affect our consolidated financial results and our ability to service the Notes.

In addition to any disruption in the global financial markets, the economic, regulatory and political conditions in some of the countries where we have operations or are pursuing investment opportunities may present increased risks related to, among others, inflation, foreign currency exchange rate fluctuations, currency repatriation restrictions, nationalization, renegotiation, privatization, availability of financing on suitable terms, customer creditworthiness, construction delays, business interruption, political instability, civil unrest, guerilla activity, terrorism, expropriation, trade sanctions, contract nullification and changes in law, regulations or tax policy. We may not choose to or be capable of either fully insuring against or effectively hedging these risks.

Poor performance of plan and fund investments and other factors impacting the pension and other postretirement benefit plans and nuclear decommissioning and mine reclamation trust funds could unfavorably impact our cash flows and liquidity.

Costs of providing our defined benefit pension and other postretirement benefit plans and costs associated with the joint trustee plan to which PacifiCorp contributes depend upon a number of factors, including the rates of return on plan assets, the level and nature of benefits provided, discount rates, mortality assumptions, the interest rates used to measure required minimum funding levels, the funded status of the plans, changes in benefit design, tax deductibility and funding limits, changes in laws and government regulation and our required or voluntary contributions made to the plans. Certain of our pension and other postretirement benefit plans are in underfunded positions. Even if sustained growth in the investments over future periods increases the value of these plans’ assets, we will likely be required to make cash contributions to fund these plans in the future. Additionally, our plans have investments in domestic and foreign equity and debt securities and other investments that are subject to loss. Losses from investments could add to the volatility, size and timing of future contributions.

Furthermore, the funded status of the United Mine Workers of America (“UMWA”) 1974 Pension Plan multiemployer plan to which PacifiCorp’s subsidiary previously contributed is considered critical and declining. PacifiCorp’s subsidiary involuntarily withdrew from the UMWA 1974 Pension Plan in June 2015 when the UMWA employees ceased performing work for the subsidiary. PacifiCorp has recorded its best estimate of the withdrawal obligation. If participating employers withdraw from a multiemployer plan, the unfunded obligations of the plan may be borne by the remaining participating employers, including any employers that withdrew during the three years prior to a mass withdrawal.

In addition, MidAmerican Energy is required to fund over time the projected costs of decommissioning Quad Cities Station, a nuclear power plant, and Bridger Coal Company, a joint venture of PacifiCorp’s subsidiary, Pacific Minerals, Inc., is required to fund projected mine reclamation costs. Funds that MidAmerican Energy has invested in a nuclear decommissioning trust and PacifiCorp has invested in a mine reclamation trust are invested in debt and equity securities and poor performance of these investments will reduce the amount of funds available for their intended purpose, which could require MidAmerican Energy or PacifiCorp to make additional cash contributions. Such cash funding obligations, which are also impacted by the other factors described above, could have a material impact on MidAmerican Energy’s or PacifiCorp’s liquidity by reducing their available cash.

Inflation and changes in commodity prices and fuel transportation costs may adversely affect our consolidated financial results and our ability to service the Notes.

Inflation and increases in commodity prices and fuel transportation costs may affect us and our subsidiaries by increasing both operating and capital costs. As a result of existing rate agreements, contractual arrangements or competitive price pressures, we and our subsidiaries may not be able to pass the costs of inflation on to our customers. If we and our subsidiaries are unable to manage cost increases or pass them on to our customers, our consolidated financial results and our ability to service the Notes could be adversely affected.

Cyclical fluctuations in the residential real estate brokerage and mortgage businesses could adversely affect HomeServices.

The residential real estate brokerage and mortgage industries tend to experience cycles of greater and lesser activity and profitability and are typically affected by changes in economic conditions, which are beyond HomeServices’ control. Any of the following, among others, are examples of items that could have a material adverse effect on HomeServices’ businesses by causing a general decline in the number of home sales, sale prices or the number of home financings which, in turn, would adversely affect its financial results:

• rising interest rates or unemployment rates, including a sustained high unemployment rate in the United States;

21

• periods of economic slowdown or recession in the markets served;

• decreasing home affordability;

• lack of available mortgage credit for potential homebuyers, such as the reduced availability of credit, which may continue into future periods;

• inadequate home inventory levels;

• nontraditional sources of new competition; and

• changes in applicable tax law.

Disruptions in the financial markets could affect our and our subsidiaries’ ability to obtain debt financing or to draw upon or renew existing credit facilities and have other adverse effects on us and our subsidiaries, including our ability to service the Notes.

Disruptions in the financial markets could affect our and our subsidiaries’ ability to obtain debt financing or to draw upon or renew existing credit facilities and have other adverse effects on us and our subsidiaries, including our ability to service the Notes. Significant dislocations and liquidity disruptions in the United States, Great Britain, Canada and global credit markets, such as those that occurred in 2008 and 2009, may materially impact liquidity in the bank and debt capital markets, making financing terms less attractive for borrowers that are able to find financing and, in other cases, may cause certain types of debt financing, or any financing, to be unavailable. Additionally, economic uncertainty in the United States or globally may adversely affect the United States’ credit markets and could negatively impact our and our subsidiaries’ ability to access funds on favorable terms or at all. If we or our subsidiaries are unable to access the bank and debt markets to meet liquidity and capital expenditure needs, it may adversely affect the timing and amount of our capital expenditures, acquisition financing and our consolidated financial results and our ability to service the Notes.

Potential changes in accounting standards may impact our consolidated financial results and disclosures in the future, which may change the way analysts measure our business or financial performance.

The Financial Accounting Standards Board (“FASB”) and the SEC continuously make changes to accounting standards and disclosure and other financial reporting requirements. New or revised accounting standards and requirements issued by the FASB or the SEC or new accounting orders issued by the FERC could significantly impact our consolidated financial results and disclosures. For example, beginning in 2018 all changes in the fair values of equity securities (whether realized or unrealized) will be recognized as gains or losses in our consolidated financial statements. Accordingly, periodic changes in our reported net income will likely be subject to significant variability.

We and our subsidiaries are involved in a variety of legal proceedings, the outcomes of which are uncertain and could adversely affect our consolidated financial results and our ability to service the Notes.

We and our subsidiaries are, and in the future may become, a party to a variety of legal proceedings. Litigation is subject to many uncertainties, and we cannot predict the outcome of individual matters with certainty. It is possible that the final resolution of some of the matters in which we and our subsidiaries are involved could result in additional material payments substantially in excess of established reserves or in terms that could require us or our subsidiaries to change business practices and procedures or divest ownership of assets. Further, litigation could result in the imposition of financial penalties or injunctions and adverse regulatory consequences, any of which could limit our ability to take certain desired actions or the denial of needed permits, licenses or regulatory authority to conduct our business, including the siting or permitting of facilities. Any of these outcomes could have a material adverse effect on our consolidated financial results and our ability to service the Notes.

22

Other Risks Associated with the Notes

Your ability to transfer the Notes is limited by the absence of a market for the Notes, and a trading market for the Notes may not develop.

There is no existing public trading market for the Notes and a market for the Notes might not develop and you may not be able to sell the Notes or obtain a suitable price. If such a market were to develop, the Notes could trade at prices that may be higher or lower than their initial offering price depending on many factors, including prevailing interest rates, our operating results and the market for similar securities. We do not intend to apply for listing of the Notes on a securities exchange or an automated dealer quotation system. As a result, it may be difficult for you to find a buyer for the Notes at the time you want to sell them and, even if you find a buyer, you might not obtain the price you want.

You may not be able to sell your Initial Notes if you do not exchange them for registered Exchange Notes in the Exchange Offer.

If you do not exchange your Initial Notes for registered Exchange Notes in the Exchange Offer, your Initial Notes will continue to be subject to the restrictions on transfer as stated in the legends on the Initial Notes. In general, you may not offer, sell or otherwise transfer the Initial Notes in the U.S. unless they are:

• registered under the Securities Act;

• offered or sold under an exemption from the Securities Act and applicable state securities laws; or

• offered or sold in a transaction not subject to the Securities Act and applicable state securities laws.

We do not currently anticipate that we will register any untendered Initial Notes under the Securities Act. Except for limited instances involving the initial purchasers or holders of Initial Notes who are not eligible to participate in the Exchange Offer or who do not receive freely transferable Exchange Notes in the Exchange Offer, following completion of the Exchange Offer, we will not be under any further obligation to register the Initial Notes under the Securities Act under the registration rights agreement or otherwise. Also, if the Exchange Offer is completed on the terms and within the time period contemplated by this prospectus, no additional interest attributable to a failure to timely comply with our obligations under the registration rights agreement will be payable on your Initial Notes.

Your ability to sell your Initial Notes may be significantly more limited and the price at which you may be able to sell your Initial Notes may be significantly lower if you do not exchange them for registered Exchange Notes in the Exchange Offer.

To the extent that Initial Notes are exchanged for registered Exchange Notes in the Exchange Offer, the trading market for the Initial Notes that remain outstanding may be significantly more limited. As a result, the liquidity of the Initial Notes not tendered for exchange could be adversely affected. The extent of the market for Initial Notes will depend upon a number of factors, including the number of holders and dollar amount of Initial Notes remaining outstanding and the interest of securities firms in maintaining a market in the Initial Notes. An issue of securities with a lesser outstanding market value available for trading, which is called the “float,” may command a lower price than would be comparable to an issue of securities with a greater float. As a result, the market price for Initial Notes that are not exchanged in the Exchange Offer may be affected adversely to the extent that Initial Notes exchanged in the Exchange Offer reduce the float or the number of holders. The reduced float and number of holders also may make the trading price of the Initial Notes that are not exchanged more volatile.

23

There are state securities law restrictions on the resale of the Exchange Notes.

In order to comply with the securities laws of certain jurisdictions, the Exchange Notes (like the Initial Notes) may not be offered or resold by any holder unless they have been registered or qualified for sale in such jurisdictions or an exemption from registration or qualification is available and the requirements of such exemption have been satisfied. We do not currently intend to register or qualify the resale of the Exchange Notes in any such jurisdictions. However, an exemption is generally available for sales to registered broker-dealers and certain institutional buyers. Other exemptions under applicable state securities laws may also be available.

We will not accept your Initial Notes for exchange if you fail to follow the Exchange Offer procedures and, as a result, your Initial Notes will continue to be subject to existing transfer restrictions and you may not be able to sell your Initial Notes.

We will issue Exchange Notes in exchange for Initial Notes tendered and accepted for exchange pursuant to the Exchange Offer only after compliance by you with all of the conditions of the Exchange Offer described elsewhere in this prospectus under the caption, “The Exchange Offer—How to Tender,” including timely (i) receipt by the exchange agent of (a) a properly completed and duly executed letter of transmittal, together with any required signature guarantees and any other required documents and (b) the certificate(s) representing the Initial Notes being tendered; (ii) compliance with the procedures for book-entry transfers described elsewhere in this prospectus; or (iii) compliance with the guaranteed delivery procedures set forth elsewhere in this prospectus. We are under no duty to give notification of defects or irregularities with respect to the tenders of Initial Notes for exchange. If there are defects or irregularities with respect to your tender of Initial Notes, we will not accept your Initial Notes for exchange. See “The Exchange Offer.”

26

USE OF PROCEEDS

We will not receive any proceeds from the issuance of the Exchange Notes in the Exchange Offer. The Exchange Notes will evidence the same debt as the Initial Notes tendered in exchange for Exchange Notes. Accordingly, the issuance of the Exchange Notes will not result in any change in our outstanding indebtedness.

THE EXCHANGE OFFER

Purpose of the Exchange Offer

On January 5, 2018, we privately placed the Initial Notes in a transaction exempt from registration under the Securities Act. Accordingly, the Initial Notes may not be reoffered, resold or otherwise transferred in the United States unless so registered or unless an exemption from the Securities Act registration requirements is available. Pursuant to a registration rights agreement with the initial purchasers of the Initial Notes, we agreed, for the benefit of holders of the Initial Notes, to:

• prepare and file an exchange offer registration statement with the SEC with respect to a registered offer to exchange the Initial Notes for Exchange Notes issued under the same indenture as the Initial Notes, in the same aggregate principal amount as and with terms that are identical in all material respects to the corresponding series of Initial Notes except that the Exchange Notes will generally be freely transferable;

• use our reasonable best efforts to cause the exchange offer registration statement to become effective under the Securities Act on or before January 5, 2019 (within 365 days after January 5, 2018, the date on which we issued the Initial Notes) (such 365th day being the “Exchange Offer Effectiveness Deadline” for the exchange offer registration statement); and

• promptly after the exchange offer registration statement is declared effective, offer the Exchange Notes in exchange for surrender of the Initial Notes.

We will be entitled to consummate the Exchange Offer on the expiration date (as defined below) provided that we have accepted all Initial Notes previously validly tendered in accordance with the terms set forth in this prospectus and the applicable letter of transmittal.

In addition, under certain circumstances described below, we may be required to file a shelf registration statement to cover resales of certain of the Notes.

If we do not comply with certain of our obligations under the registration rights agreement, we must pay additional interest on the Initial Notes in addition to the interest that is otherwise due on the Notes. The purpose of the Exchange Offer is to fulfill our obligations with respect to the registration rights agreement.

If you are a broker-dealer that receives Exchange Notes for its own account in exchange for Initial Notes, where you acquired such Initial Notes as a result of market-making activities or other trading activities, you must acknowledge that you will deliver a prospectus in connection with any resale of such Exchange Notes. See “Plan of Distribution.”

Terms of the Exchange

Upon the terms and subject to the conditions contained in this prospectus and in the letters of transmittal that accompany this prospectus, we are offering to exchange (i) $1,000 in principal amount of the 2021 Exchange Notes for each $1,000 in principal amount of the 2021 Initial Notes, (ii) $1,000 in principal amount of the 2023 Exchange Notes for each $1,000 in principal amount of the 2023 Initial Notes, (iii) $1,000 in principal amount of the 2028 Exchange Notes for each $1,000 in principal amount of the 2028 Initial Notes and (iv) $1,000 in

27

principal amount of the 2048 Exchange Notes for each $1,000 in principal amount of the 2048 Initial Notes. The terms of the Exchange Notes are identical in all material respects to the terms of the corresponding series of Initial Notes except that the Exchange Notes will generally be freely transferable. The Exchange Notes will evidence the same debt as the Initial Notes and will be entitled to the benefits of the indenture. Any Initial Notes that remain outstanding after the consummation of the Exchange Offer, together with all Exchange Notes issued in connection with the Exchange Offer, will be treated as a single class of securities under the indenture. See “Description of the Notes.”

The Exchange Offer is not conditioned on any minimum aggregate principal amount of Initial Notes being tendered for exchange.

Based on existing interpretations of the Securities Act by the staff of the SEC set forth in severalno-action letters to third parties, and subject to the immediately following sentence, we believe that you may offer for resale, resell and otherwise transfer the Exchange Notes without further compliance with the registration and prospectus delivery provisions of the Securities Act. However, if you are an “affiliate” (within the meaning of the Securities Act) of ours or you intend to participate in the Exchange Offer for the purpose of distributing the Exchange Notes or you are a broker-dealer (within the meaning of the Securities Act) that acquired notes in a transaction other than as part of its market-making or other trading activities and who has arranged or has an understanding with any person to participate in the distribution of the Exchange Notes, you:

(1) will not be able to rely on the interpretations by the staff of the SEC set forth in the above-mentionedno-action letters;

(2) will not be able to tender your notes in the Exchange Offer; and

(3) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any sale or transfer of your notes unless such sale or transfer is made pursuant to an exemption from such requirements

Subject to exceptions for certain holders, to participate in the Exchange Offer you will be required to represent to us at the time of the consummation of the Exchange Offer, among other things, that: (i) you are not an affiliate of ours; (ii) any Exchange Notes to be received by you will be acquired in the ordinary course of your business; and (iii) at the time of commencement of the Exchange Offer, you have no arrangement or understanding with any person to participate in a distribution (within the meaning of the Securities Act) of the notes. In addition, in connection with any resales of Exchange Notes, any broker-dealer who acquired Exchange Notes for its own account as a result of market-making activities or other trading activities must deliver a prospectus meeting the requirements of the Securities Act. The SEC has taken the position that such a broker-dealer may fulfill its prospectus delivery requirements with respect to the Exchange Notes (other than a resale of an unsold allotment from the initial sale of the Initial Notes) with this prospectus. Under the registration rights agreement, we are required to allow a broker-dealer and other persons with similar prospectus delivery requirements, if any, to use this prospectus in connection with the resale of such Exchange Notes for a period of time not less than 120 days following the consummation of the Exchange Offer. If you are a broker-dealer that receives Exchange Notes for its own account in exchange for Initial Notes, where you acquired such Initial Notes as a result of market-making activities or other trading activities, you acknowledge that you will deliver a prospectus in connection with any resale of such Exchange Notes. See “Plan of Distribution.”

You will not be required by us to pay brokerage commissions or fees or, subject to the instructions in the applicable letter of transmittal, transfer taxes relating to your exchange of Initial Notes for Exchange Notes in the Exchange Offer.

Shelf Registration Statement

If:

• we are not permitted to effect the Exchange Offer because of any change in law or in applicable interpretations of such law by the staff of the SEC;

28

• the Exchange Offer is not consummated by the 40th day after the date on which the exchange offer registration statement was declared effective;

• any of the initial purchasers of the Initial Notes so requests with respect to the Initial Notes not eligible to be exchanged for Exchange Notes in the Exchange Offer and held by it following the consummation of Exchange Offer;

• any holder of the Notes (other than a broker-dealer electing to exchange Initial Notes acquired for its own account as a result of market-making or other trading activities for Exchange Notes) is not eligible

• to participate in the Exchange Offer and any such holder so requests for any reason other than the failure by such holder to make a timely and valid tender in accordance with the terms of Exchange Offer; or

• any holder of the Notes (other than a broker-dealer electing to exchange Initial Notes acquired for its own account as a result of market-making or other trading activities for Exchange Notes) participates in the Exchange Offer but does not receive freely tradable Exchange Notes on the date of the exchange and any such holder so requests for any reason other than the failure by such holder to make a timely and valid tender in accordance with the terms of Exchange Offer,

we will:

• as promptly as practicable prepare and file with the SEC a “shelf” registration statement relating to the offer and sale (on a continuous basis) of the Notes that are not otherwise freely tradable;

• use our reasonable best efforts to cause the shelf registration statement to be declared effective not later than the latter to occur of the date that is (i) 150 days after the date on which our obligation to file the shelf registration arises or (ii) January 5, 2019 (365 days after January 5, 2018, the date on which we issued the Initial Notes) (such 150th or 365th day, as the case may be, being the “Shelf Effectiveness Deadline” for the shelf registration statement); and

• use our reasonable best efforts to keep the shelf registration statement continuously effective until the later of (i) one year from the date on which we issued the Initial Notes (subject to extension under certain circumstances) or (ii) 90 days from the date of effectiveness of such shelf registration statement, or such shorter period ending when all the Notes covered by the shelf registration statement have been sold pursuant to the shelf registration statement or are no longer “Transfer Restricted Securities” as defined in the registration rights agreement.

The foregoing obligations are subject to our right to postpone or suspend the filing or effectiveness of any shelf registration statement (or exchange offer registration statement) if such action is required by law or taken by us in good faith and for valid business reasons in accordance with the terms of the registration rights agreement.

You will not be entitled, except if you were an initial purchaser of the Initial Notes, to have your Notes registered under any shelf registration statement (if one is filed), unless you agree in writing to be bound by the applicable provisions of the registration rights agreement. In order to sell your Notes under the shelf registration statement, you generally must be named as a selling security holder in the related prospectus and must deliver a prospectus to purchasers. Consequently, you will be subject to the civil liability provisions under the Securities Act in connection with those sales and indemnification obligations under the registration rights agreement.

Additional Interest

A registration default will be deemed to have occurred:

(1) if the exchange offer registration statement is not declared effective on or before January 5, 2019 (within 365 days after January 5, 2018, the date on which we issued the Initial Notes);

29

(2) with respect to certain notes that qualify as “Transfer Restricted Securities,” if a required shelf registration statement is not declared effective on or prior to the applicable Effectiveness Deadline; or

(3) with respect to any Transfer Restricted Securities, on and after the applicable Shelf Effectiveness Deadline or Exchange Offer Effectiveness Deadline (plus an additional 30 days in respect of an exchange offer registration statement), either the exchange offer registration statement or the shelf registration statement has been declared effective, but such registration statement or the related prospectus thereafter ceases to be effective or usable (subject to certain exceptions) in connection with resales of such Initial Notes or Exchange Notes for the periods specified and in accordance with the registration rights agreement because (i) any event occurs as a result of which the related prospectus forming part of such registration statement would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, (ii) it shall be necessary to amend such registration statement or supplement the related prospectus to comply with the Securities Act or the Exchange Act, or the respective rules thereunder or (iii) of a Suspension (as defined in the registration rights agreement) by us in accordance with provisions and procedures provided in the registration rights agreement.

Additional interest will accrue on the Initial Notes subject to such registration default, for so long as they constitute Transfer Restricted Securities, at a rate of 0.50% per annum from and including the date on which any such registration default occurs to but excluding the date on which all such registration defaults have ceased to be continuing. In no event will such additional interest be payable for periods after January 5, 2020. At our written request, the Representative, as such term is defined in the registration rights agreement, may, in its sole discretion, agree to shorten such penalty interest period. In each case, such additional interest is payable in addition to any other interest payable from time to time with respect to the Initial Notes and the Exchange Notes. The Exchange Notes will not contain any additional provisions regarding the payment of additional interest.

Expiration Date; Extensions; Termination; Amendments

The Exchange Offer expires on the expiration date. The expiration date is 5:00 p.m., New York City time, on May 2, 2018, unless we in our sole discretion extend the period during which the Exchange Offer is open, in which event the expiration date is the latest time and date on which the Exchange Offer, as so extended by us, expires. We reserve the right to extend the Exchange Offer at any time and from time to time by giving written notice to The Bank of New York Mellon Trust Company, N.A., as the exchange agent, before 9:00 a.m., New York City time, on the first business day following the previously scheduled expiration date and by timely public announcement communicated in accordance with applicable law or regulation. During any extension of the Exchange Offer, all Initial Notes previously tendered pursuant to the Exchange Offer and not validly withdrawn will remain subject to the Exchange Offer.

The exchange date will occur promptly after the expiration date. We expressly reserve the right to (i) terminate the Exchange Offer and not accept for exchange any Initial Notes if any of the events set forth below under “—Conditions to the Exchange Offer” shall have occurred and shall not have been waived by us and (ii) amend the terms of the Exchange Offer in accordance with applicable law or regulation, whether before or after any tender of the Initial Notes. If any such termination or amendment occurs, we will notify the exchange agent in writing and will either issue a press release or give written notice to the holders of the Initial Notes as promptly as practicable. Unless we terminate the Exchange Offer prior to 5:00 p.m., New York City time, on the expiration date, we will exchange the Initial Notes for the Exchange Notes on the exchange date.

If we waive any material condition to the Exchange Offer, or amend the Exchange Offer in any other material respect, and if at the time that notice of such waiver or amendment is first published, sent or given to holders of Initial Notes in the manner specified above, the Exchange Offer is scheduled to expire at any time earlier than the expiration of a period ending on the fifth business day from, and including, the date that such notice is first so published, sent or given, then the Exchange Offer will be extended until the expiration of such period of five business days.

30

This prospectus and the related letters of transmittal and other relevant materials will be mailed by us to record holders of Initial Notes and will be furnished to brokers, banks and similar persons whose names, or the names of whose nominees, appear on the lists of holders for subsequent transmittal to beneficial owners of Initial Notes.

How to Tender

The tender to us of Initial Notes by you pursuant to one of the procedures set forth below will constitute an agreement between you and us in accordance with the terms and subject to the conditions set forth herein and in the applicable letter of transmittal.

General Procedures. To validly tender the Initial Notes pursuant to the Exchange Offer, either:

(1) (i) a properly completed and duly executed letter of transmittal or a facsimile thereof (all references in this prospectus to the letter of transmittal shall be deemed to include a facsimile thereof), together with any required signature guarantees and any other documents required by the letter of transmittal, must be received by the exchange agent at its address or facsimile number set forth on the back cover of this prospectus on or prior to the expiration date and (ii) the certificate(s) representing the Initial Notes being tendered must be received by the exchange agent on or prior to the expiration date;

(2) for book-entry transfers, (i) an “agent’s message” (as defined below) properly transmitted through the Depositary Trust Company’s (“DTC”) Automated Tender Offer Program (“ATOP”), together with any other documents required by the letter of transmittal, must be received by the exchange agent at its office set forth on the back cover of this prospectus on or prior to the expiration date and (ii) the Initial Notes must be tendered pursuant to the procedures for book-entry transfer set forth below and a confirmation of a book-entry transfer of such Initial Notes into the exchange agent’s account at the DTC (which we refer to as a Book-Entry Confirmation) must be received by the exchange agent on or prior to the expiration date; or

(3) the guaranteed delivery procedures set forth below must be complied with.

The term “agent’s message” means a message, transmitted by the DTC and received by the exchange agent and forming part of a Book-Entry Confirmation, which states that DTC has received an express acknowledgment from a participant tendering Initial Notes that are the subject of the Book-Entry Confirmation that the participant has received and agrees to be bound by the terms of the letter of transmittal, and that we may enforce that agreement against the participant.

If tendered Initial Notes are registered in the name of the signer of the letter of transmittal and the Exchange Notes to be issued in exchange therefor are to be issued (and any untendered Initial Notes are to be reissued) in the name of the registered holder, the signature of such signer need not be guaranteed. In any other case, the tendered Initial Notes must be endorsed or accompanied by written instruments of transfer in form satisfactory to us and duly executed by the registered holder and the signature on the endorsement or instrument of transfer must be guaranteed by a firm, which we refer to as an Eligible Institution, that is a member of a recognized signature guarantee medallion program within the meaning of Rule17Ad-15 under the Exchange Act. If the Exchange Notes and/or Initial Notes not exchanged are to be delivered to an address other than that of the registered holder appearing on the note register for the Initial Notes, the signature on the letter of transmittal must be guaranteed by an Eligible Institution.

Any beneficial owner whose Initial Notes are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and who wishes to tender Initial Notes should contact such holder promptly and instruct such holder to tender Initial Notes on such beneficial owner’s behalf. If such beneficial owner wishes to tender such Initial Notes himself, such beneficial owner must, prior to completing and executing the letter of transmittal and delivering such Initial Notes, either make appropriate arrangements to register ownership of the Initial Notes in such beneficial owner’s name or follow the procedures described in the immediately preceding paragraph. The transfer of record ownership may take considerable time.

31

Book-Entry Transfer. The exchange agent will make a request to establish an account with respect to the Initial Notes at DTC for purposes of the Exchange Offer within two business days after the date of this prospectus. Any financial institution that is a participant in DTC’s systems may utilize DTC’s ATOP procedures to tender Initial Notes and may make book-entry delivery of Initial Notes by causing DTC to transfer such Initial Notes into the exchange agent’s account at DTC in accordance with DTC’s ATOP procedures for transfer. However, although delivery of Initial Notes may be effected through book-entry transfer at DTC, the letter of transmittal, with any required signature guarantees and any other required documents, must, in any case, be transmitted to and received by the exchange agent at its address or facsimile number set forth on the back cover of this prospectus on or prior to the expiration date, unless the holder either (i) complies with the guaranteed delivery procedures described below or (ii) sends an agent’s message through ATOP.

If delivery is made through ATOP, the exchange for the Initial Notes so tendered will be made only after a Book-Entry Confirmation and an agent’s message and any other documents required by the letter of transmittal have been received by the exchange agent, in each case on or prior to the expiration date.

The method of delivery of Initial Notes and all other documents is at your election and risk. If sent by mail, we recommend that you use registered mail, return receipt requested, obtain proper insurance, and complete the mailing sufficiently in advance of the expiration date to permit delivery to the exchange agent on or before the expiration date. Delivery of documents to DTC does not constitute delivery to the exchange agent.

Guaranteed Delivery Procedures. If a holder desires to accept the Exchange Offer and time will not permit a letter of transmittal or Initial Notes to reach the exchange agent on or before the expiration date, or the procedures for book-entry transfer set forth above cannot be completed on a timely basis, a tender may nevertheless be effected, provided that all of the following guaranteed delivery procedures are complied with:

(1) such tenders are made by or through an Eligible Institution;

(2) the exchange agent has received at its office set forth on the back cover hereof on or prior to the expiration date a properly completed and duly executed notice of guaranteed delivery, by telegram, telex, facsimile transmission, letter or courier, or an electronic message transmitted through ATOP with respect to guaranteed delivery for book-entry transfers, (i) setting forth the name and address of the tendering holder, the name(s) in which the Initial Notes are registered, the principal amount of the Initial Notes and, if possible, the certificate number(s) of the Initial Notes to be tendered, (ii) stating that the tender is being made thereby and (iii) guaranteeing that within three New York Stock Exchange trading days after the date of execution by the Eligible Institution of such notice of guaranteed delivery, or transmission of such electronic message through ATOP for book-entry transfers, the certificates for all physically tendered Initial Notes, in proper form for transfer, or a Book-Entry Confirmation in the case of book-entry transfers, together with a properly completed and duly executed letter of transmittal with any required signature guarantees, or a properly transmitted agent’s message through ATOP in the case of book-entry transfers, and any other documents required by the letter of transmittal, will be deposited by the Eligible Institution with the exchange agent; and

(3) the certificates for all physically tendered Initial Notes, in proper form for transfer, or a Book-Entry Confirmation in the case of book-entry transfers, together with a properly completed and duly executed letter of transmittal with any required signature guarantees, or a properly transmitted agent’s message through ATOP in the case of book-entry transfers, and any other documents required by the letter of transmittal, must be received by the exchange agent within three New York Stock Exchange trading days after the date of execution by the Eligible Institution of the notice of guaranteed delivery or transmission of such electronic message through ATOP with respect to guaranteed delivery for book-entry transfers.

Unless all of the guaranteed delivery procedures set forth in the preceding paragraph are complied with, we may, at our option, reject the tender. Copies of a Notice of Guaranteed Delivery which may be used by Eligible

32

Institutions for the purposes described in this paragraph are being delivered with this prospectus and the related letter of transmittal. A tender will be deemed to have been received as of the date when the tendering holder’s properly completed and duly signed letter of transmittal accompanied by the Initial Notes (or agent’s message accompanied by a Book-Entry Confirmation in the case of a book-entry transfer) is received by the exchange agent. Issuances of Exchange Notes in exchange for Initial Notes tendered pursuant to a notice of guaranteed delivery by an Eligible Institution or an electronic message transmitted through ATOP with respect to guaranteed delivery for book-entry transfers will be made only against deposit of the letter of transmittal (and any other required documents) and the tendered Initial Notes or, in the case of a book-entry transfer, against deposit of an agent’s message through ATOP (and any other required documents) and a timely Book-Entry Confirmation.

All questions as to the validity, form, eligibility (including time of receipt) and acceptance for exchange of any tender of Initial Notes will be determined by us and our determination will be final and binding. We reserve the absolute right to reject any or all tenders not in proper form or the acceptances for exchange of which may, in the opinion of our counsel, be unlawful. We also reserve the absolute right to waive any of the conditions of the Exchange Offer or any defect or irregularities in tenders of any particular holder whether or not similar defects or irregularities are waived in the case of other holders. None of us, the exchange agent or any other person will be under any duty to give notification of any defects or irregularities in tenders or shall incur any liability for failure to give any such notification. Our interpretation of the terms and conditions of the Exchange Offer (including the letters of transmittal and the instructions thereto) will be final and binding.

Terms and Conditions of the Letters of Transmittal

The letters of transmittal contain, among other things, the following terms and conditions, which are part of the Exchange Offer.

The party tendering Initial Notes for exchange, whom we refer to as the Transferor, exchanges, assigns and transfers the Initial Notes to us and irrevocably constitutes and appoints the exchange agent as the Transferor’s agent andattorney-in-fact to cause the Initial Notes to be assigned, transferred and exchanged. The Transferor represents and warrants that it has full power and authority to tender, exchange, assign and transfer the Initial Notes and to acquire Exchange Notes issuable upon the exchange of such tendered Initial Notes, and that, when the same are accepted for exchange, we will acquire good and unencumbered title to the tendered Initial Notes, free and clear of all liens, restrictions, charges and encumbrances and not subject to any adverse claim. The Transferor also warrants that it will, upon request, execute and deliver any additional documents deemed by us to be necessary or desirable to complete the exchange, assignment and transfer of tendered Initial Notes. The Transferor further agrees that acceptance of any tendered Initial Notes by us and the issuance of Exchange Notes in exchange therefor shall constitute performance in full by us of our obligations under the registration rights agreement and that we shall have no further obligations or liabilities thereunder (except in certain limited circumstances). All authority conferred by the Transferor will survive the death or incapacity of the Transferor and every obligation of the Transferor shall be binding upon the heirs, legal representatives, successors, assigns, executors and administrators of such Transferor. See “—Terms of the Exchange.”

Withdrawal Rights

Initial notes tendered pursuant to the Exchange Offer may be withdrawn at any time prior to the expiration date. For a withdrawal to be effective, a written or facsimile transmission notice of withdrawal must be timely received by the exchange agent at its address set forth on the back cover of this prospectus. Any such notice of withdrawal must specify the person named in the letter of transmittal as having tendered Initial Notes to be withdrawn, the certificate numbers of Initial Notes to be withdrawn, the principal amount of Initial Notes to be withdrawn (which must be an authorized denomination), a statement that such holder is withdrawing his election to have such Initial Notes exchanged, and the name of the registered holder of such Initial Notes, and must be

33

signed by the holder in the same manner as the original signature on the letter of transmittal (including any required signature guarantees) or be accompanied by documents of transfer sufficient to have the trustee register the transfer of such Initial Notes into the name of the person withdrawing the tender. The exchange agent will return the properly withdrawn Initial Notes promptly following receipt of notice of withdrawal. If Initial Notes have been tendered pursuant to the procedures for book-entry transfer set forth above, any notice of withdrawal must specify the name and number of the account at DTC to be credited with the withdrawn Initial Notes or otherwise comply with DTC’s procedures, and in such case the Initial Notes will be credited to such account by the exchange agent promptly after withdrawal. All questions as to the validity of notices of withdrawals, including time of receipt, will be determined by us, and our determination will be final and binding on all parties.

Acceptance of Initial Notes for Exchange; Delivery of Exchange Notes

Upon the terms and subject to the conditions of the Exchange Offer, the acceptance for exchange of Initial Notes validly tendered and not withdrawn and the issuance of the Exchange Notes will be made on the exchange date. For the purposes of the Exchange Offer, we shall be deemed to have accepted for exchange validly tendered Initial Notes when, as and if we have given written notice thereof to the exchange agent.

In all cases, delivery of Exchange Notes in exchange for Initial Notes tendered and accepted pursuant to this Exchange Offer will be made only after timely receipt by the exchange agent of:

(1) a certificate or certificates representing the Initial Notes or, in the case of book-entry transfers, a Book-Entry Confirmation;

(2) a properly completed and duly executed letter of transmittal or, in the case of book-entry transfers, an agent’s message properly transmitted through ATOP; and

(3) any other documents required by the letter of transmittal.

The exchange agent will act as agent for the tendering holders of Initial Notes for the purposes of receiving Exchange Notes from us and causing the Initial Notes to be assigned, transferred and exchanged. Upon the terms and subject to the conditions of the Exchange Offer, delivery of Exchange Notes to be issued in exchange for accepted Initial Notes will be made by the exchange agent promptly after the expiration of the Exchange Offer. Initial notes not accepted for exchange by us will be returned without expense to the tendering holders (or in the case of Initial Notes tendered by book-entry transfer into the exchange agent’s account at DTC pursuant to the procedures described above, suchnon-exchanged Initial Notes will be credited to an account maintained with DTC) promptly following the expiration date or, if we terminate the Exchange Offer prior to the expiration date, promptly after the Exchange Offer is so terminated.

Conditions to the Exchange Offer

We are not required to accept for exchange, or to issue Exchange Notes in exchange for, any outstanding Initial Notes. We may terminate or extend the Exchange Offer by oral or written notice to the exchange agent and by timely public announcement communicated in accordance with applicable law or regulation if any of the following shall have occurred:

• any federal law, statute, rule, regulation or interpretation of the staff of the SEC has been proposed, adopted or enacted that, in our judgment, might impair our ability to proceed with the Exchange Offer or otherwise make it inadvisable to proceed with the Exchange Offer;

• an action or proceeding has been instituted or threatened in any court or by any governmental agency that, in our judgment, might impair our ability to proceed with the Exchange Offer or otherwise make it inadvisable to proceed with the Exchange Offer;

• there has occurred a material adverse development in any existing action or proceeding that might impair our ability to proceed with the Exchange Offer or otherwise make it inadvisable to proceed with the Exchange Offer;

34

• any stop order is threatened or in effect with respect to the registration statement of which this prospectus is a part or the qualification of the indenture under the U.S. Trust Indenture Act of 1939, as amended;

• all governmental approvals that we deem necessary for the consummation of the Exchange Offer have not been obtained;

• there is a change in the current interpretation by the staff of the SEC which permits holders who have made the required representations to us to resell, offer for resale, or otherwise transfer Exchange Notes issued in the Exchange Offer without registration of the Exchange Notes and delivery of a prospectus; or

• a material adverse change shall have occurred in our business, condition, operations or prospects.

The foregoing conditions are for our sole benefit and may be asserted by us with respect to all or any portion of the Exchange Offer regardless of the circumstances (including any action or inaction by us) giving rise to such condition or may be waived by us in whole or in part at any time or from time to time in our sole discretion. The failure by us at any time to exercise any of the foregoing rights will not be deemed a waiver of any such right, and each right will be deemed an ongoing right which may be asserted at any time or from time to time. In addition, we have reserved the right, notwithstanding the satisfaction of each of the foregoing conditions, to amend the terms of the Exchange Offer in accordance with applicable law or regulation.

Any determination by us concerning the fulfillment ornon-fulfillment of any conditions will be final and binding upon all parties.

Exchange Agent

The Bank of New York Mellon Trust Company, N.A. has been appointed as the exchange agent for the Exchange Offer. Letters of transmittal must be addressed to the exchange agent at its address set forth on the back cover page of this prospectus. Delivery to an address other than as set forth herein, or transmissions of instructions via a facsimile or telex number other than the ones set forth herein, will not constitute a valid delivery. The Bank of New York Mellon Trust Company, N.A. is the trustee under the indenture. The Bank of New York Mellon Trust Company, N.A. (or one of its affiliates) currently serves, and may in the future serve, as trustee under indentures evidencing other indebtedness of us and our affiliates. The Bank of New York Mellon Trust Company, N.A. (or one of its affiliates) is also, and may in the future be, a lender under credit facilities for us and our affiliates.

Solicitation of Tenders; Expenses

We have not retained any dealer-manager or similar agent in connection with the Exchange Offer and will not make any payments to brokers, dealers or others for soliciting acceptances of the Exchange Offer. We will, however, pay the exchange agent reasonable and customary fees for its services and will reimburse it for reasonableout-of-pocket expenses in connection therewith. We will also pay brokerage houses and other custodians, nominees and fiduciaries the reasonableout-of-pocket expenses incurred by them in forwarding tenders for their customers. The expenses to be incurred in connection with the Exchange Offer, including the fees and expenses of the exchange agent and printing, accounting and legal fees, will be paid by us and are estimated at approximately $400,000.

No dealer, salesperson or other individual has been authorized to give any information or to make any representations not contained in this prospectus in connection with the Exchange Offer. If given or made, such information or representations must not be relied upon as having been authorized by us. Neither the delivery of this prospectus nor any exchange made hereunder shall, under any circumstances, create any implication that there has been no change in our affairs since the respective dates as of which information is given herein.

35

The Exchange Offer is not being made to (nor will tenders be accepted from or on behalf of) holders of Initial Notes in any jurisdiction in which the making of the Exchange Offer or the acceptance thereof would not be in compliance with the laws of such jurisdiction. However, we may, at our discretion, take such action as we may deem necessary to make the Exchange Offer in any such jurisdiction and extend the Exchange Offer to holders of Initial Notes in such jurisdiction. In any jurisdiction the securities laws or blue sky laws of which require the Exchange Offer to be made by a licensed broker or dealer, the Exchange Offer is being made on behalf of us by one or more registered brokers or dealers which are licensed under the laws of such jurisdiction.

Appraisal Rights

You will not have appraisal rights in connection with the Exchange Offer.

U.S. Federal Income Tax Consequences

The exchange of Initial Notes for Exchange Notes is not expected to be a taxable exchange for U.S. federal income tax purposes, and holders are not expected to realize any taxable gain or loss as a result of such exchange. See “Certain U.S. Federal Income Tax Considerations.”

Other

Participation in the Exchange Offer is voluntary and you should carefully consider whether to accept. You are urged to consult your financial and tax advisors in making your own decisions on what action to take.

As a result of the making of, and upon acceptance for exchange of all validly tendered Initial Notes pursuant to the terms of, this Exchange Offer, we will have fulfilled a covenant contained in the terms of the Initial Notes and the registration rights agreement. Holders of the Initial Notes who do not tender their Initial Notes in the Exchange Offer will continue to hold such Initial Notes and will be entitled to all the rights, and limitations applicable thereto, under the indenture, except for any such rights under the registration rights agreement which by their terms terminate or cease to have further effect as a result of the making of this Exchange Offer. See “Description of the Notes.” All untendered Initial Notes will continue to be subject to the restriction on transfer set forth in the indenture. To the extent that Initial Notes are tendered and accepted in the Exchange Offer, the trading market, if any, for the Initial Notes could be adversely affected. See “Risk Factors—Your ability to sell your Initial Notes may be significantly more limited and the price at which you may be able to sell your Initial Notes may be significantly lower if you do not exchange them for registered Exchange Notes in the Exchange Offer.”

We may in the future seek to acquire untendered Initial Notes in open market or privately negotiated transactions, through subsequent exchange offers or otherwise. We have no present plan to acquire any Initial Notes that are not tendered in the Exchange Offer.

DESCRIPTION OF THE NOTES

The Initial Notes were, and the Exchange Notes will be, issued pursuant to a supplemental indenture to the indenture, dated as of October 4, 2002, as amended to date, between us and The Bank of New York Mellon Trust Company, N.A., as trustee. The term “indenture” when used in this prospectus will refer to the indenture as amended by all supplemental indentures executed and delivered on or prior to the date on which the Notes are issued and sold. The terms of the Notes include those stated in the indenture and those made part of the indenture by reference to the U.S. Trust Indenture Act of 1939, as amended.

On March 24, 2006, we issued $1,700,000,000 of our 6.125% Senior Bonds due 2036 (hereafter referred to as the series E bonds), on May 11, 2007, we issued $550,000,000 of our 5.95% Senior Bonds due 2037 (hereafter referred to as the series F bonds), on August 28, 2007, we issued $1,000,000,000 of our 6.50% Senior Bonds due 2037 (hereafter referred to as the series G bonds), on March 28, 2008, we issued $650,000,000 of our 5.75% Senior Notes due 2018 (hereafter referred to as the series H notes), on November 8, 2013, we issued $350,000,000 of our 2.00% Senior Notes due 2018 (hereafter referred to as the series K notes), $500,000,000 of our 3.75% Senior Notes due 2023 (hereafter referred to as the series L notes) and $750,000,000 of our 5.15% Senior Notes due 2043 (hereafter referred to as the series M notes), and on December 4, 2014, we issued $350,000,000 of our 2.40% Senior Notes due 2020 (hereafter referred to as the series N notes), $400,000,000 of our 3.50% Senior Notes due 2025 (hereafter referred to as the series O notes) and $750,000,000 of our 4.50% Senior Notes due 2045 (hereafter referred to as the series P notes) in each case pursuant to the indenture. On December 13, 2017, we commenced a tender offer relating to certain outstanding indebtedness, including the 8.480% Bonds, the series E bonds, the series F bonds and the series G bonds. Pursuant to the tender offer, $173,973,000 aggregate principal amount of the 8.480% Bonds, $30,086,000 aggregate principal amount of the series E bonds and $775,145,000 aggregate principal amount of the series G bonds were accepted for purchase in the tender offer, and were canceled and are no longer outstanding.

The following description is a summary of the material provisions of the indenture and the related registration rights agreement. It does not restate those agreements in their entirety. We urge you to read the indenture and the registration rights agreement because they, and not this description, define your rights as a holder of the Notes. The definitions of certain capitalized terms used in the following summary are set forth below under “—Definitions.”

General

The indenture does not limit the aggregate principal amount of the debt securities that may be issued thereunder and provides that debt securities may be issued from time to time in one or more series.

The 2021 Initial Notes were initially offered in the aggregate principal amount of $450,000,000, the 2023 Initial Notes were initially offered in the aggregate principal amount of $400,000,000, the 2028 Initial Notes were initially offered in the aggregate principal amount of $600,000,000 and the 2048 Initial Notes were initially offered in the aggregate principal amount of $750,000,000. We may, without the consent of the holders, increase such principal amount in the future on the same terms and conditions (except for the issue date and offering price and, if applicable, the initial interest payment date and the initial interest accrual date) and with the same CUSIP number(s) as the Notes being offered hereby; provided that any additional notes that are not fungible with the Notes for U.S. federal income tax purposes shall have a separate CUSIP or other identifying number.

The 2021 Initial Notes bear, and the 2021 Exchange Notes will bear, interest at the rate of 2.375% per annum and will mature on January 15, 2021. The 2023 Initial Notes bear, and the 2023 Exchange Notes will bear, interest at the rate of 2.800% per annum and will mature on January 15, 2023. The 2028 Initial Notes bear,

39

and the 2028 Exchange Notes will bear, interest at the rate of 3.250% per annum and will mature on April 15, 2028. The 2048 Initial Notes bear, and the 2048 Exchange Notes will bear, interest at the rate of 3.800% per annum and will mature on July 15, 2048. Interest will be payable on each of the 2021 Notes, the 2023 Notes and the 2048 Notes semi-annually in arrears on each January 15 and July 15, beginning on July 15, 2018, to the holders thereof at the close of business on the preceding January 1 and July 1, respectively (whether or not a business day). Interest will be payable on the 2028 Notes semiannually in arrears on each April 15 and October 15, beginning on April 15, 2018, to the holders thereof at the close of business on the preceding April 1 and October 1, respectively (whether or not a business day). Interest on each series of the Notes will be computed on the basis of a360-day year of twelve30-day months.

Each series of Initial Notes were, and each series of Exchange Notes will be, issued without coupons and in fully registered form only in denominations of $2,000 and any integral multiple of $1,000 in excess thereof.

We file certain reports and other information with the SEC in accordance with the requirements of Sections 13 and 15(d) under the Exchange Act. See “Where You Can Find More Information.” At any time that Sections 13 and 15(d) cease to apply to us, we have covenanted in the indenture to file comparable reports and information with the trustee and the SEC, and mail such reports and information to holders of securities at their registered addresses, for so long as any securities remain outstanding.

If (i) a registration statement of which this prospectus is a part is not declared effective by the SEC within 365 days after January 5, 2018 (the closing date of the offering of the Initial Notes), (ii) a shelf registration statement with respect to the resale of the Notes which is required under the registration rights agreement is not declared effective by the SEC within 150 days after our obligation to file such shelf registration statement arises (but in any event not prior to 365 days after January 5, 2018) or (iii) any of the foregoing registration statements (or the prospectuses related thereto) after being declared effective by the SEC cease to be so effective or usable (subject to certain exceptions) in connection with certain resales of the Initial Notes or the Exchange Notes for the periods specified and in accordance with the registration rights agreement, the interest rate on the Notes that are then subject to such cessation or other registration default will increase by 0.50% from and including the date on which any such event occurs until such event ceases to be continuing. The Exchange Offer and the registration rights are more fully described under “The Exchange Offer” above.

Any Initial Notes that remain outstanding after the consummation of the Exchange Offer, together with all Exchange Notes issued in connection with the Exchange Offer, will be treated as a single class of securities under the indenture.

For purposes of determining the 2021 Make-Whole Amount, the 2023 Make-Whole Amount, the 2028 Make-Whole Amount and the 2048 Make-Whole Amount, the following definitions apply:

“Comparable Treasury Issue” means, with respect to a series of Notes, the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Notes of such series (assuming, for this purpose, that such Notes matured on their par call date) to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such Notes.

41

“Comparable Treasury Price” means, with respect to any redemption date, the Reference Treasury Dealer Quotation for such redemption date.

“Independent Investment Banker” means an investment banking institution of international standing appointed by the Company.

“Reference Treasury Dealer” means a primary U.S. government securities dealer in New York City appointed by the Company.

“Reference Treasury Dealer Quotation” means, with respect to the Reference Treasury Dealer and any redemption date, the average, as determined by BHE of the bid and asked prices for the applicable Comparable Treasury Issue (expressed in each case as a percentage of its principal amount and quoted in writing to BHE by such Reference Treasury Dealer at 5:00 p.m. on the third business day in New York City preceding such redemption date).

“Treasury Rate” means the rate per annum equal to the semi-annual equivalent or interpolated (on a daycount basis) yield to maturity of the applicable Comparable Treasury Issue, assuming a price for such Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the applicable Comparable Treasury Price for that redemption date.

Notice of any redemption is required to be mailed at least 30 days but not more than 60 days before the redemption date to each registered holder of Notes to be redeemed.

If less than all of the Notes of a series are to be redeemed at any time, selection of the Notes of a series for redemption is required to be made by the trustee by such method as the Notes trustee deems fair and appropriate; provided, that if the Notes of a series to be redeemed are represented by one or more Global Notes (as hereinafter defined), beneficial interests in such Notes will be selected for redemption by the Depositary (as hereinafter defined) in accordance with its standard procedures therefor.

Upon the payment of the redemption price, plus any accrued and unpaid interest, if any, to the date of redemption, interest will cease to accrue on and after the applicable redemption date on the Notes or such series or portions thereof called for redemption.

No Sinking Fund

No series of the Notes will be subject to any mandatory sinking fund.

Ranking

Each series of the Notes are our general, unsecured senior obligations and rank pari passu in right of payment with all of our other existing and future senior unsecured obligations (including the remaining outstanding 8.480% Bonds, series E bonds and series G bonds, and the series F bonds, the series H notes, the series K notes, the series L notes, the series M notes, the series N notes, the series O notes and the series P notes) and senior in right of payment to all of our existing and future subordinated obligations. The Notes will be effectively subordinated to all of our existing and future secured obligations and to all existing and future obligations of our Subsidiaries. As of December 31, 2017, we had outstanding senior unsecured debt of $6.5 billion, which does not include the $2.2 billion of Initial Notes issued on January 5, 2018, junior subordinated debentures of $100 million, short-term borrowings of $3.3 billion, guarantees and letters of credit in respect of subsidiary and equity method investments aggregating $332 million and commitments, subject to satisfaction of certain specified conditions, to provide equity contributions in support of renewable tax equity investments totaling $265 million. Our consolidated Subsidiaries also have significant amounts of outstanding debt, which totaled $29.8 billion as of December 31, 2017. These amounts exclude (a) trade debt, (b) preferred stock obligations, (c) our Subsidiaries’ letters of credit in respect of their debts, and (d) our share of the outstanding debt of our own or our Subsidiaries’ equity method investments.

42

Covenants

Except as set forth under “—Defeasance and Discharge—Covenant Defeasance” below, for so long as any securities remain outstanding, we will comply with the terms of the covenants set forth below.

Restrictions on Liens

We will not be permitted to pledge, mortgage, hypothecate or permit to exist any pledge, mortgage or other Lien upon any property or assets at any time directly owned by us to secure any indebtedness for money borrowed which is incurred, issued, assumed or guaranteed by us (“Indebtedness for Borrowed Money”), without making effective provisions whereby the outstanding securities will be equally and ratably secured with any and all such Indebtedness for Borrowed Money and with any other Indebtedness for Borrowed Money similarly entitled to be equally and ratably secured; provided, however, that this restriction will not apply to or prevent the creation or existence of:

(1) any Liens existing prior to the issuance of the securities;

(2) purchase money Liens which do not exceed the cost or value of the purchased property or assets;

(3) any Liens not to exceed 10% of Consolidated Net Tangible Assets; and

(4) any Liens on property or assets granted in connection with extending, renewing, replacing or refinancing in whole or in part the Indebtedness for Borrowed Money (including, without limitation, increasing the principal amount of such Indebtedness for Borrowed Money) secured by Liens described in the foregoing clauses (1) through (3), provided that the Liens in connection with any such extension, renewal, replacement or refinancing will be limited to the specific property or assets that was subject to the original Lien.

In the event that we propose to pledge, mortgage or hypothecate or permit to exist any pledge, mortgage or other Lien upon any property or assets at any time directly owned by us to secure any Indebtedness for Borrowed Money, other than as permitted by clauses (1) through (4) of the previous paragraph, we are required to give prior written notice thereof to the trustee and we are required, prior to or simultaneously with such pledge, mortgage or hypothecation, to secure effectively all the securities equally and ratably with such Indebtedness for Borrowed Money.

The foregoing covenant will not restrict the ability of our Subsidiaries and affiliates to pledge, mortgage, hypothecate or permit to exist any mortgage, pledge or Lien upon their property or assets, in connection with project financings or otherwise.

Consolidation, Merger, Conveyance, Sale or Lease

So long as any securities are outstanding, we will not be permitted to consolidate with or merge with or into any other person, or convey, transfer or lease our consolidated properties and assets substantially as an entirety to any person, or permit any person to merge into or consolidate with us, unless (1) we are the surviving or continuing corporation or the surviving or continuing corporation or purchaser or lessee is a corporation incorporated under the laws of the U.S., one of the states thereof or the District of Columbia or Canada and assumes our obligations under the securities and under the indenture and (2) immediately before and after such transaction, no event of default under the indenture shall have occurred and be continuing.

Except for a sale of our consolidated properties and assets substantially as an entirety as provided above, and other than properties or assets required to be sold to conform with laws or governmental regulations, we will not be permitted, directly or indirectly, to sell or otherwise dispose of any of our consolidated properties or assets (other than short-term, readily marketable investments purchased for cash management purposes with funds not representing the proceeds of other asset sales) if on a pro forma basis, the aggregate net book value of all such

43

sales during the most recent12-month period would exceed 10% of Consolidated Net Tangible Assets computed as of the end of the most recent quarter preceding such sale; provided, however, that (1) any such sales shall be disregarded for purposes of this 10% limitation if the net proceeds are invested in properties or assets in similar or related lines of business of us and our Subsidiaries, including, without limitation, any of the lines of business in which we or any of our Subsidiaries are engaged on the date of such sale or disposition, and (2) we may sell or otherwise dispose of consolidated properties and assets in excess of such 10% limitation if the net proceeds from such sales or dispositions, which are not reinvested as provided above, are retained by us as cash or Cash Equivalents or used to retire Indebtedness for Borrowed Money of us (other than Indebtedness for Borrowed Money which is subordinated to the securities) and our Subsidiaries.

The covenant described immediately above includes a phrase relating to a conveyance, transfer or lease of our consolidated properties and assets “substantially as an entirety.” Although there is a limited body of case law interpreting the phrase “substantially as an entirety,” there is no precise established definition of the phrase under applicable law. Accordingly, the nature and extent of the restriction on our ability to convey, transfer or lease our consolidated properties or assets substantially as an entirety, and the protections provided to the holders of securities by such restriction, may be uncertain.

Purchase of Securities Upon a Change of Control

Upon the occurrence of a Change of Control, each holder of the securities will have the right to require that we repurchase all or any part of such holder’s securities at a purchase price in cash equal to 101% of the principal thereof on the date of purchase plus any accrued interest, if any, to the date of purchase.

The Change of Control provisions may not be waived by the trustee or by our board of directors, and any modification thereof must be approved by each holder. Nevertheless, the Change of Control provisions will not necessarily afford protection to holders, including protection against an adverse effect on the value of the securities of any series, including the Notes of each series, in the event that we or our Subsidiaries incur additional Debt, whether through recapitalizations or otherwise.

Within 30 days following a Change of Control, BHE will mail a notice to each holder of the securities with a copy to the trustee, stating the following:

(1) that a Change of Control has occurred and that such holder has the right to require us to purchase such holder’s securities at the purchase price described above, in principal amounts of $2,000 and integral multiples of $1,000 in excess thereof (the “Change of Control Offer”), provided that any unpurchased portion of a note must be in a principal amount equal to $2,000 or an integral of $1,000 in excess thereof;

(2) the circumstances and relevant facts regarding such Change of Control (including information with respect to pro forma historical income, cash flow and capitalization after giving effect to such Change of Control);

(3) the purchase date (which will not be earlier than 30 days nor later than 60 days from the date such notice is mailed) (the “Purchase Date”);

(4) that after the Purchase Date interest on such security will continue to accrue (except as provided in clause (5));

(5) that any security properly tendered pursuant to the Change of Control Offer will cease to accrue interest after the Purchase Date (assuming sufficient moneys for the purchase thereof are deposited with the trustee);

(6) that holders electing to have a security purchased pursuant to a Change of Control Offer will be required to surrender the security, with the form entitled “Option of Holder To Elect Purchase” on the reverse of the security completed, to the paying agent at the address specified in the notice prior to the close of business on the fifth business day prior to the Purchase Date;

44

(7) that a holder will be entitled to withdraw such holder’s election if the paying agent receives, not later than the close of business on the third business day (or such shorter periods as may be required by applicable law) preceding the Purchase Date, facsimile transmission or letter setting forth the name of the holder, the principal amount of securities the holder delivered for purchase, and a statement that such holder is withdrawing his election to have such securities of such series purchased; and

(8) that holders that elect to have their securities purchased only in part will be issued new securities having a principal amount equal to the portion of the securities that were surrendered but not tendered and purchased.

On the Purchase Date, we will be required to (1) accept for payment all securities or portions thereof tendered pursuant to the Change of Control Offer, (2) deposit with the trustee money sufficient to pay the purchase price of all securities or portions thereof so tendered for purchase and (3) deliver or cause to be delivered to the trustee the securities properly tendered together with an officer’s certificate identifying the securities or portions thereof tendered to us for purchase. The trustee will promptly mail, to the holders of the securities properly tendered and purchased, payment in an amount equal to the purchase price, and promptly authenticate and mail to each holder a new security having a principal amount equal to any portion of such holder’s securities that were surrendered but not tendered and purchased. We will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Purchase Date.

If we are prohibited by applicable law from making the Change of Control Offer or purchasing securities of any series, including the Notes of each series, thereunder, we need not make a Change of Control Offer pursuant to this covenant for so long as such prohibition is in effect.

We will be required to comply with all applicable tender offer rules, including, without limitation, Rule14e-1 under the Exchange Act, in connection with a Change of Control Offer.

Events of Default

An event of default with respect to the securities of any series, including the Notes of each series, is defined in the indenture as being any one of the following events:

(1) default as to the payment of principal of, or premium, if any, on any security of that series or as to any payment required in connection with a Change of Control;

(2) default as to the payment of interest on any security of that series for 30 days after payment is due;

(3) failure to make a Change of Control Offer required under the covenants described under “Purchase of Securities Upon a Change of Control” above or a failure to purchase the securities of that series tendered in respect of such Change of Control Offer;

(4) default in the performance, or breach, of any of our covenants, agreements or warranties contained in the indenture and the securities of that series and such failure continues for 30 days after written notice is given to us by the trustee or to us and the trustee by the holders of at least a majority in aggregate principal amount outstanding of the securities of that series, as provided in the indenture;

(5) default on any other Debt of ours or any Significant Subsidiary (other than Debt that isNon-Recourse to us) if either (x) such default results from failure to pay principal of such Debt in excess of $100 million when due after any applicable grace period or (y) as a result of such default, the maturity of such Debt has been accelerated prior to its scheduled maturity and such default has not been cured within the applicable grace period, and such acceleration has not been rescinded, and the principal amount of such Debt, together with the principal amount of any other Debt of ours and our Significant Subsidiaries (not including Debt that isNon-Recourse to us) that is in default as to principal, or the maturity of which has been accelerated, aggregates $100 million or more;

45

(6) the entry by a court of one or more judgments or orders against us or any Significant Subsidiary for the payment of money that in the aggregate exceeds $100 million (excluding (i) the amount thereof covered by insurance or by a bond written by a person other than an affiliate of ours (other than, with respect to the series E bonds, the series F bonds, the series H notes, the series K notes, the series L notes, the series M notes, the series N notes, the series O notes and the series P notes, Berkshire Hathaway or any of its affiliates that provide commercial insurance in the ordinary course of their business) and (ii) judgments that areNon-Recourse to us), which judgments or orders have not been vacated, discharged or satisfied or stayed pending appeal within 60 days from the entry thereof, provided that such a judgment or order will not be an event of default if such judgment or order does not require any payment by us; and

(7) certain events involving bankruptcy, insolvency or reorganization of us or any of our Significant Subsidiaries.

The indenture provides that the trustee may withhold notice to the holders of any default (except in payment of principal of, premium, if any, or interest on any series of securities and any payment required in connection with a Change of Control) if the trustee considers it in the interest of holders to do so.

The indenture provides that if an event of default with respect to the securities of any series at the time outstanding, including the Notes of each series (other than an event of bankruptcy, insolvency or reorganization of us or a Significant Subsidiary) has occurred and is continuing, either the trustee or (i) in the case of any event of default described in clause (1) or (2) above, the holders of at least 33% in aggregate principal amount of the securities of that series then outstanding, or (ii) in the case of any other event of default, the holders of at least a majority in aggregate principal amount of the securities of that series then outstanding, may declare the principal of and any accrued interest on all securities of that series to be due and payable immediately, but upon certain conditions such declaration may be annulled and past defaults (except, unless theretofore cured, a default in payment of principal of, premium, if any, or interest on the securities of that series or any payment required in connection with a Change of Control) may be waived by the holders of a majority in principal amount of the securities of that series then outstanding. If an event of default due to the bankruptcy, insolvency or reorganization of us or a Significant Subsidiary occurs, the indenture provides that the entire principal amount of and any interest accrued on all securities will become immediately due and payable without any action by the trustee, the holders of securities or any other person.

The holders of a majority in principal amount of the securities of any series then outstanding, including the Notes of each series, will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee under the indenture with respect to the securities of such series, subject to certain limitations specified in the indenture, provided that the holders of securities of such series must have offered to the trustee reasonable indemnity against expenses and liabilities.

The indenture requires the annual filing by us with the trustee of a written statement as to our knowledge of the existence of any default in the performance and observance of any of the covenants contained in the indenture.

Modification of the Indenture

The indenture contains provisions permitting us and the trustee, with the consent of the holders of not less than a majority in principal amount of the outstanding securities of each series affected by the modification, including the Notes, to modify the indenture or the rights of the holders of such series, except that no such modification may (1) extend the stated maturity of the principal of or any installment of interest on the securities, reduce the principal amount thereof or the interest rate thereon, reduce any premium payable on redemption or purchase thereof, impair the right of any holder to institute suit for the enforcement of any such payment on or after the stated maturity thereof or make any change in the covenants regarding a Change of Control or the related definitions without the consent of the holder of each outstanding security so affected, or (2) reduce the percentage of any series of securities, the consent of the holders of which is required for any such modification, without the consent of the holders of all series of securities then outstanding.

46

Defeasance and Discharge

Legal Defeasance

The indenture provides that we will be deemed to have paid and will be discharged from any and all obligations in respect of the Notes of each series or any other series of securities issued thereunder on the 123rd day after the deposit referred to below has been made (or immediately if an opinion of counsel is delivered to the effect described in clause (B)(3)(y) below), and the provisions of the indenture will cease to be applicable with respect to the securities of such series (except for, among other matters, certain obligations to register the transfer or exchange of the securities of such series, to replace stolen, lost or mutilated securities of such series, to maintain paying agents and to hold monies for payment in trust) if, among other things:

(A) We have deposited with the trustee, in trust, money and/or U.S. Government Obligations that through the payment of interest and principal in respect thereof in accordance with their terms will provide money in an amount sufficient to pay the principal of, premium, if any, and accrued and unpaid interest on the applicable securities, on the respective stated maturities of the securities or, if we make arrangements satisfactory to the trustee for the redemption of the securities prior to their stated maturity, on any earlier redemption date in accordance with the terms of the indenture and the applicable securities;

(B) We have delivered to the trustee:

(1) either (x) an opinion of counsel to the effect that beneficial owners of securities of such series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such deposit, defeasance and discharge and will be subject to U.S. federal income tax on the same amount and in the same manner and at the same times as would have been the case if such deposit, defeasance and discharge had not occurred and we had paid or redeemed such securities on the applicable stated maturity dates, which opinion of counsel must be based upon a ruling of the U.S. Internal Revenue Service (the “IRS”) to the same effect or a change in applicable U.S. federal income tax law or related Treasury regulations after the date of the indenture, or (y) a ruling directed to the trustee or we received from the IRS to the same effect as the aforementioned opinion of counsel;

(2) an opinion of counsel to the effect that the creation of the defeasance trust does not violate the Investment Company Act of 1940; and

(3) an opinion of counsel to the effect that either (x) after the passage of 123 days following the deposit referred to in clause (A) above, the trust fund will not be subject to the effect of Section 547 or 548 of the U.S. Bankruptcy Code or Section 15 of the New York Debtor and Creditor Law or (y) based upon existing precedents, if the matter were properly briefed, a court should hold that the deposit of moneys and/or U.S. Government Obligations as provided in clause (A) above would not constitute a preference voidable under Section 547 or 548 of the U.S. Bankruptcy Code or Section 15 of the New York Debtor and Creditor Law;

(C) if at such time the securities are listed on a national securities exchange, we have delivered to the trustee an opinion of counsel to the effect that the securities will not be delisted as a result of such deposit, defeasance and discharge; and

(D) immediately after giving effect to such deposit referred to in clause (A) above on a pro forma basis, no event of default under the indenture, or event that after the giving of notice or lapse of time or both would become an event of default, will have occurred and be continuing on the date of such deposit or (unless an opinion of counsel is delivered to the effect described in clause (B)(3)(y) above) during the period ending on the 123rd day after the date of such deposit, and such deposit and discharge will not result in a breach or violation of, or constitute a default under, any other material agreement or instrument to which we are a party or by which we are bound.

47

Covenant Defeasance

The indenture further provides that the provisions of the covenants described herein under “Covenants— Restrictions on Liens,” “—Consolidation, Merger, Conveyance, Sale or Lease” and “Purchase of Securities Upon a Change of Control,” clauses (3) and (4) under “Events of Default” with respect to such covenants, clause (2) under “Events of Default” with respect to offers to purchase upon a Change of Control as described above and clauses (5) and (6) under “Events of Default” will cease to be applicable to us and our Subsidiaries upon the satisfaction of the provisions described in clauses (A), (B), (C) and (D) of the preceding paragraph; provided, however, that with respect to such covenant defeasance, the opinion of counsel described in clause (B)(1)(x) above need not be based upon any ruling of the IRS or change in applicable U.S. federal income tax law or related Treasury regulations.

Defeasance and Certain Other Events of Default

If we exercise our option to omit compliance with certain covenants and provisions of the indenture with respect to the securities of any series, including the Notes of each series, as described in the immediately preceding paragraph and any series of securities is declared due and payable because of the occurrence of an event of default that remains applicable, the amount of money and/or U.S. Government Obligations on deposit with the trustee will be sufficient to pay amounts due on such securities at the time of their stated maturity or scheduled redemption, but may not be sufficient to pay amounts due on such securities at the time of acceleration resulting from such event of default. We will remain liable for such payments.

Governing Law

The indenture and the securities will be governed by, and construed in accordance with, the law of the State of New York, includingSection 5-1401 of the New York General Obligations Law, but otherwise without regard to conflict of laws rules.

Trustee

The Bank of New York Mellon Trust Company, N.A. is the trustee under the indenture. The Bank of New York Mellon Trust Company, N.A. (or one of its affiliates) currently serves, and may in the future serve, as trustee under indentures evidencing other indebtedness of ours and our affiliates. The Bank of New York Mellon Trust Company, N.A. (or one of its affiliates) is also, and may in the future be, a lender under credit facilities for us and our affiliates. The trustee will be under no obligation to exercise any of the rights or powers vested in it by the indenture at the request or direction of any of the holders pursuant to the indenture, unless such holders have offered to the trustee security or indemnity satisfactory to the trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request or direction.

Definitions

(7) all Debt of others Guaranteed by such person to the extent such Debt is Guaranteed by such person;

(8) all Redeemable Stock valued at the greater of its voluntary or involuntary liquidation preference plus accrued and unpaid dividends; and

For purposes of determining any particular amount of Debt that is or would be outstanding, Guarantees of, or obligations with respect to letters of credit or similar instruments supporting (to the extent the foregoing constitutes Debt), Debt otherwise included in the determination of such particular amount will not be included. For purposes of determining compliance with the indenture, in the event that an item of Debt meets the criteria of more than one of the types of Debt described in the above clauses, we, in our sole discretion, will classify such item of Debt and only be required to include the amount and type of such Debt in one of such clauses.

“Guarantee” means any obligation, contingent or otherwise, of any person directly or indirectly guaranteeing any Debt of any other person and, without limiting the generality of the foregoing, any Debt

50

obligation, direct or indirect, contingent or otherwise, of such person (1) to purchase or pay (or advance or supply funds for the purchase or payment of) such Debt of such other person (whether arising by virtue of partnership arrangements (other than solely by reason of being a general partner of a partnership), or by agreement to keepwell, to purchase assets, goods, securities or services or totake-or-pay, or to maintain financial statement conditions or otherwise) or (2) entered into for purposes of assuring in any other manner the obligee of such Debt of the payment thereof or to protect such obligee against loss in respect thereof (in whole or in part), provided that the term “Guarantee” will not include endorsements for collection or deposit in the ordinary course of business or the grant of a lien in connection with anyNon-Recourse Debt. The term “Guarantee” used as a verb has a corresponding meaning.

“Intangible Assets” means, as of the date of determination thereof, all of our assets properly classified as intangible assets determined on a consolidated basis in accordance with GAAP.

“Rating Decline” means the occurrence of the following on, or within 90 days after, the earlier of (1) the occurrence of a Change of Control and (2) the earlier of (x) the date of public notice of the occurrence of a Change of Control or (y) the date of the public notice of our intention to effect a Change of Control (the “Rating Date”), which period will be extended so long as the rating of the Notes is under publicly announced consideration for possible downgrading by any of the Rating Agencies: the rating of such Notes by both such Rating Agencies is reduced below BBB+, in the case of S&P, and Baa1, in the case of Moody’s.

“Redeemable Stock” means any class or series of Capital Stock of any person that by its terms or otherwise is (1) required to be redeemed prior to the stated maturity of any series of the securities, (2) redeemable at the option of the holder of such class or series of Capital Stock at any time prior to the stated maturity of any series

51

of the securities or (3) convertible into or exchangeable for Capital Stock referred to in clause (1) or (2) above or Debt having a scheduled maturity prior to the stated maturity of any series of the securities, provided that any Capital Stock that would not constitute Redeemable Stock but for provisions thereof giving holders thereof the right to require us to purchase or redeem such Capital Stock upon the occurrence of a “change of control” occurring prior to the stated maturity of any series of the securities will not constitute Redeemable Stock if the “change of control” provisions applicable to such Capital Stock are no more favorable to the holders of such Capital Stock than the provisions contained in the covenants described under “Purchase of Securities Upon a Change of Control” above.

“Redemption Date” means any date on which we redeem all or any portion of the securities in accordance with the terms of the indenture.

“Significant Subsidiary” means a “significant subsidiary” as defined in Rule1-02(w) of RegulationS-X under the Securities Act and the Exchange Act, substituting 20 percent for 10 percent each place it appears therein. Unless the context otherwise clearly requires, any reference to a “Significant Subsidiary” is a reference to a Significant Subsidiary of ours.

“Voting Stock” means, with respect to any person, Capital Stock of any class or kind ordinarily having the power to vote for the election of directors (or persons fulfilling similar responsibilities) of such person.

Global Notes; Book-Entry System

The Initial Notes were, and the Exchange Notes will be, issued under a book-entry system in the form of one or more global notes (each, a “Global Note”). Each Global Note with respect to the Initial Notes was, and each Global Note with respect to the Exchange Notes will be, deposited with, or on behalf of, a depositary, which will be The Depository Trust Company, New York, New York (the “Depositary”). The Global Notes with respect to the Initial Notes were, and the Global Notes with respect to the Exchange Notes will be, registered in the name of the Depositary or its nominee.

The Initial Notes were not issued in certificated form and, except under the limited circumstances described below, owners of beneficial interests in the Global Notes will not be entitled to physical delivery of the Notes in

52

certificated form. The Global Notes may not be transferred except as a whole by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any nominee to a successor of the Depositary or a nominee of such successor.

The Depositary is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. The Depositary holds securities that its participants (“Direct Participants”) deposit with the Depositary. The Depositary also facilitates the post-trade settlement among Direct Participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in Direct Participants’ accounts, thereby eliminating the need for physical movement of securities certificates. Direct Participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, including Euroclear Bank S.A./N.V. as operator of the Euroclear System (“Euroclear”) and Clearstream Banking,société anonyme(“Clearstream”). The Depositary is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC, in turn, is owned by a number of Direct Participants and Members of the National Securities Clearing Corporation, Government Securities Clearing Corporation, MBS Clearing Corporation and Emerging Markets Clearing Corporation, also subsidiaries of DTCC, as well as by the New York Stock Exchange, Inc., the American Stock Exchange LLC and the National Association of Securities Dealers, Inc. Access to the Depositary system is also available to others such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). The rules applicable to the Depositary and its Direct and Indirect Participants are on file with the SEC.

Purchases of the securities under the Depositary system must be made by or through Direct Participants, which will receive a credit for the securities on the Depositary’s records. The ownership interest of each actual purchaser of each security (“Beneficial Owner”) is in turn to be recorded on the Direct and Indirect Participants’ records. Beneficial Owners will not receive written confirmation from the Depositary of their purchase, but Beneficial Owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in the securities are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in securities, except in the event that use of the book-entry system for the securities is discontinued.

To facilitate subsequent transfers, all Notes deposited by Direct Participants with the Depositary will be registered in the name of the Depositary’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of the Depositary. The deposit of Notes with the Depositary and their registration in the name of Cede & Co. or such other nominee effect no change in beneficial ownership. The Depositary has no knowledge of the actual Beneficial Owners of the Notes; the Depositary’s records reflect only the identity of the Direct Participants to whose accounts such Notes are credited, which may or may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by the Depositary to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Neither the Depositary nor Cede & Co. (nor any other nominee of the Depositary) will consent or vote with respect to the Notes unless authorized by a Direct Participant in accordance with the Depositary’s procedures. Under its usual procedures, the Depositary mails an Omnibus Proxy to us as soon as possible after the record

53

date. The Omnibus Proxy assigns Cede & Co.’s consenting or voting rights to those Direct Participants to whose accounts the securities are credited on the record date (identified in a listing attached to the Omnibus Proxy).

Principal (and premium, if any) and interest payments on the Notes and any redemption payments will be made to Cede & Co. (or such other nominee as may be requested by an authorized representative of the Depositary). The Depositary’s practice is to credit Direct Participants’ accounts upon the Depositary’s receipt of funds and corresponding detail information from us or the trustee on the payable date in accordance with their respective holdings shown on the Depositary’s records. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such Participant and not of the Depositary, the trustee or us, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of principal (and premium, if any), interest and any redemption proceeds to Cede & Co. (or such other nominee as may be requested by an authorized representative of the Depositary) is our responsibility, disbursements of such payments to Direct Participants shall be the responsibility of the Depositary, and disbursement of such payments to the Beneficial Owners shall be the responsibility of Direct and Indirect Participants.

The Depositary may discontinue providing its services as securities depositary with respect to the Notes at any time by giving reasonable notice to us or the trustee. Under such circumstances, in the event that a successor securities depositary is not obtained, certificated Notes are required to be printed and delivered. We may decide to discontinue use of the system of book-entry transfers through the Depositary (or a successor securities depositary). In that event, certificated Notes will be printed and delivered.

The information in this section concerning the Depositary and the Depositary’s book-entry system has been obtained from sources that we believe to be reliable but has not been independently verified by us, the initial purchasers or the trustee.

A Global Note of any series may not be transferred except as a whole by the Depositary to a nominee or successor of the Depositary or by a nominee of the Depositary to another nominee of the Depositary. A Global Note representing Notes is exchangeable, in whole but not in part, for Notes in definitive form of like tenor and terms if (1) the Depositary notifies us that it is unwilling or unable to continue as depositary for such Global Note or if at any time the Depositary is no longer eligible to be or in good standing as a “clearing agency” registered under the Exchange Act, and in either case, a successor depositary is not appointed by us within 120 days of receipt by us of such notice or of our becoming aware of such ineligibility, (2) while such Global Note is subject to the transfer restrictions described under “Transfer Restrictions,” the book-entry interests in such Global Note cease to be eligible for Depositary services because such Notes are neither (a) rated in one of the top four categories by a nationally recognized statistical rating organization nor (b) included within a Self-Regulatory Organization system approved by the SEC for the reporting of quotation and trade information of securities eligible for transfer pursuant to Rule 144A, or (3) we in our sole discretion (subject to the procedures of the Depositary) at any time determine not to have such Notes represented by a Global Note and notify the trustee thereof. A Global Note exchangeable pursuant to the preceding sentence shall be exchangeable for Notes registered in such names and in such authorized denominations as the Depositary shall direct.

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following discussion summarizes certain U.S. federal income tax consequences of the exchange of Initial Notes for Exchange Notes. This discussion is based upon the U.S. Internal Revenue Code of 1986, as amended (the “Code”), the U.S. Treasury Regulations promulgated thereunder, administrative pronouncements, rulings and judicial decisions, all as in effect on the date hereof and all of which are subject to change or differing interpretations, possibly with retroactive effect. This summary addresses only the U.S. federal income tax consequences applicable to holders of Initial Notes that acquired the Initial Notes at their initial offering for an amount of cash equal to their issue price and held the Initial Notes as “capital assets” within the meaning of Section 1221 of the Code.

This summary does not address all of the U.S. federal income tax considerations that may be relevant to a particular holder in light of the holder’s individual circumstances or to holders subject to special rules under U.S. federal income tax laws, such as banks and other financial institutions, insurance companies, real estate investment trusts, regulated investment companies,tax-exempt organizations, entities and arrangements classified as partnerships for U.S. federal income tax purposes and other pass-through entities, dealers in securities or currencies, traders in securities that elect to use amark-to-market method of accounting, persons liable for U.S. federal alternative minimum tax, U.S. holders whose functional currency is not the U.S. dollar, U.S. expatriates, and persons holding notes as part of a “straddle,” “hedge,” “conversion transaction,” or other integrated investment. The discussion does not address any foreign, state, local ornon-income tax consequences of the exchange of Initial Notes for Exchange Notes.

This discussion is for general information purposes only, and is not intended to be and should not be construed to be, legal or tax advice to any particular holder. Holders are urged to consult their own tax advisors regarding the application of the U.S. federal income tax laws to their particular situations, the consequences under federal estate or gift tax laws, as well as foreign, state, or local laws and tax treaties, and the possible effects of changes in tax laws.

U.S. Federal Income Tax Consequences of the Exchange Offer to Holders of Initial Notes

The exchange of Initial Notes for Exchange Notes pursuant to the Exchange Offer is not expected to be a taxable exchange for U.S. federal income tax purposes. Holders of Initial Notes are not expected to realize any taxable gain or loss as a result of such exchange and are expected to have the same adjusted issue price, tax basis, and holding period in the Exchange Notes as they had in the Initial Notes immediately before the exchange. The U.S. federal income tax consequences of holding and disposing of the Exchange Notes are expected to be the same as those applicable to the Initial Notes.

CERTAIN ERISA CONSIDERATIONS

The following is a summary of certain considerations associated with the purchase and holding of the Exchange Notes by employee benefit plans that are subject to Title I of the U.S. Employee Retirement Income Security Act of 1974 (“ERISA”), plans, individual retirement accounts and other arrangements that are subject to Section 4975 of the Code or provisions under any other federal, state, local,non-U.S. or other laws, rules or regulations that are similar to such provisions of ERISA or the Code (collectively, “Similar Laws”), and entities whose underlying assets are considered to include “plan assets” of any such plan, account or arrangement (each, a “Plan”).

General Fiduciary Matters

ERISA and the Code impose certain duties on persons who are fiduciaries of a Plan subject to Title I of ERISA or Section 4975 of the Code (an “ERISA Plan”) and prohibit certain transactions involving the assets of

55

an ERISA Plan and its fiduciaries or other interested parties. Under ERISA and the Code, any person who exercises any discretionary authority or control over the administration of such an ERISA Plan or the management or disposition of the assets of such an ERISA Plan, or who renders investment advice for a fee or other compensation to such an ERISA Plan, is generally considered to be a fiduciary of the ERISA Plan.

In considering an investment in the Exchange Notes of a portion of the assets of any Plan, a fiduciary should determine whether the investment is in accordance with the documents and instruments governing the Plan and the applicable provisions of ERISA, the Code or any Similar Law relating to a fiduciary’s duties to the Plan including, without limitation, the prudence, diversification, delegation of control and prohibited transaction provisions of ERISA, the Code and any other applicable Similar Laws.

Prohibited Transaction Issues

Section 406 of ERISA and Section 4975 of the Code prohibit ERISA Plans from engaging in specified transactions involving plan assets with persons or entities who are “parties in interest,” within the meaning of ERISA, or “disqualified persons,” within the meaning of Section 4975 of the Code, unless an exemption is available. A party in interest or disqualified person who engages in anon-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and the Code. In addition, the fiduciary of the ERISA Plan that engages in such anon-exempt prohibited transaction may be subject to penalties and liabilities under ERISA and the Code. The acquisition and/or holding of Exchange Notes by an ERISA Plan with respect to which the issuer, the initial purchasers or the guarantors are considered a party in interest or a disqualified person may constitute or result in a direct or indirect prohibited transaction under Section 406 of ERISA and/or Section 4975 of the Code, unless the investment is acquired and is held in accordance with an applicable statutory, class or individual prohibited transaction exemption.

In this regard, the U.S. Department of Labor has issued prohibited transaction class exemptions (“PTCEs”) that may apply to the acquisition and holding of the Exchange Notes. These class exemptions include, without limitation, PTCE84-14 respecting transactions determined by independent qualified professional asset managers, PTCE90-1 respecting insurance company pooled separate accounts, PTCE91-38 respecting bank collective investment funds, PTCE95-60 respecting life insurance company general accounts, and PTCE96-23 respecting transactions determined byin-house asset managers. In addition, Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code provide relief from the prohibited transaction provisions of ERISA and Section 4975 of the Code for certain transactions, provided that neither the issuer of the securities nor any of its affiliates (directly or indirectly) have or exercise any discretionary authority or control or render any investment advice with respect to the assets of any ERISA Plan involved in the transaction and provided further that the ERISA Plan pays no more than adequate consideration in connection with the transaction. There can be no assurance that all of the conditions of any such exemptions will be satisfied.

Because of the foregoing, the Initial Notes should not be exchanged for Exchange Notes by any person investing “plan assets” of any Plan, unless such exchange will not constitute anon-exempt prohibited transaction under ERISA and the Code or similar violation of any applicable Similar Laws.

Representation

Accordingly, by acceptance of an Exchange Note, each purchaser and subsequent transferee will be deemed to have represented and warranted that either (i) no portion of the assets used by such purchaser or transferee to acquire or hold the Exchange Notes constitutes assets of any Plan or (ii) the exchange of the Initial Notes for the Exchange Notes or the holding of the Exchange Notes by such purchaser or transferee will not constitute anon-exempt prohibited transaction under Section 406 of ERISA, Section 4975 of the Code or a similar violation under any applicable Similar Laws.

The foregoing discussion is general in nature and is not intended to beall-inclusive. Due to the complexity of these rules and the penalties that may be imposed upon persons involved innon-exempt prohibited

56

transactions, it is particularly important that fiduciaries, or other persons considering acquiring the Exchange Notes (and holding the Exchange Notes) on behalf of, or with the assets of, any Plan, consult with their counsel regarding the potential applicability of ERISA, Section 4975 of the Code and any Similar Laws to such transactions and whether an exemption would be applicable to the acquisition and holding of the Exchange Notes (and exchange for the Exchange Notes).

Persons that acquire the Exchange Notes have the exclusive responsibility for ensuring that their acquisition and holding of the Exchange Notes complies with the fiduciary responsibility rules of ERISA and does not violate the prohibited transaction rules of ERISA, the Code or Similar Laws.

57

PLAN OF DISTRIBUTION

Based on existing interpretations of the Securities Act by the staff of the SEC set forth in severalno-action letters to third parties, and subject to the immediately following sentence, we believe that the Exchange Notes that will be issued pursuant to the Exchange Offer may be offered for resale, resold and otherwise transferred by the holders thereof without further compliance with the registration and prospectus delivery provisions of the Securities Act. However, any purchaser of Notes who is an “affiliate” (within the meaning of the Securities Act) of ours or who intends to participate in the Exchange Offer for the purpose of distributing the Exchange Notes or a broker-dealer (within the meaning of the Securities Act) that acquired Initial Notes in a transaction other than as part of its market-making or other trading activities and who has arranged or has an understanding with any person to participate in the distribution of the Exchange Notes: (1) will not be able to rely on the interpretations by the staff of the SEC set forth in the above-mentionedno-action letters; (2) will not be able to tender its Initial Notes in the Exchange Offer; and (3) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any sale or transfer of the Notes unless such sale or transfer is made pursuant to an exemption from such requirements.

Each broker-dealer that receives Exchange Notes for its own account pursuant to the Exchange Offer acknowledges that it will deliver a prospectus in connection with any resale of such Exchange Notes. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Notes received in exchange for Initial Notes where such Initial Notes were acquired as a result of market-marketing activities or other trading activities. We have agreed that, for a period of 120 days after the expiration date, we will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale.

We will not receive any proceeds from any such sale of Exchange Notes by broker-dealers. Exchange Notes received by broker-dealers for their own account pursuant to the Exchange Offer may be sold from time to time in one or more transactions in theover-the-counter market, in negotiated transactions, through the writing of options on the Exchange Notes or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or at negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer and/or the purchasers of any such Exchange Notes. Any broker-dealer that resells Exchange Notes that were received by it for its own account pursuant to the Exchange Offer and any broker or dealer that participates in a distribution of such Exchange Notes may be deemed to be an “underwriter” within the meaning of the Securities Act and any profit on any such resale of Exchange Notes and any commissions or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. The letter of transmittal states that by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.

For a period of 120 days after the expiration date, we will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests such documents in the letter of transmittal. We have agreed to pay all expenses incident to the Exchange Offer (including the expenses of one counsel for the holders of the notes) other than commissions or concessions of any brokers or dealers and will indemnify the holders of the Notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act.
