Prospectus

You should read this prospectus supplement, the accompanying prospectus, and any related free writing prospectus we file with the Securities and Exchange Commission (the “SEC”) carefully before you invest in the notes. This document contains or incorporates by reference important information you should consider before making your investment decision. You should rely only on the information contained or incorporated by reference in this prospectus supplement, the accompanying prospectus, and any such free writing prospectus. None of Berkshire Hathaway Finance Corporation (“BHFC”), Berkshire Hathaway Inc. (“Berkshire”), and the underwriters has authorized anyone else to provide you with any different or additional information. You should not assume that the information contained in this prospectus supplement, the accompanying prospectus (as updated by this prospectus supplement), or any such free writing prospectus is accurate as of any date other than its respective date or the date that is specified in those documents, or that the information Berkshire previously filed with the SEC and incorporated by reference in this prospectus supplement or the accompanying prospectus is accurate as of any date other than the date of the document incorporated by reference or the date that is specified in such document. The business, financial condition, results of operations and prospects of Berkshire and BHFC may have changed since those dates.

We are not, and the underwriters are not, making an offer of the notes in any jurisdiction where the offer or sale is not permitted. The distribution of this prospectus supplement and the accompanying prospectus and the offering or sale of the notes in some jurisdictions may be restricted by law. The notes are offered globally for sale in those jurisdictions in the United States, Europe, Asia and elsewhere where it is lawful to make such offers.

FORWARD-LOOKING INFORMATION

Certain statements contained, or incorporated by reference, in this prospectus supplement are “forward- looking” statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward- looking statements include statements that are predictive in nature, that depend upon or refer to future events or conditions, that include words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “estimates,” or similar expressions. In addition, any statements concerning future financial performance (including future revenues, earnings or growth rates), ongoing business strategies or prospects, and possible future actions by BHFC or Berkshire, which may be provided by management are also forward-looking statements as defined by the Private Securities Litigation Reform Act of 1995. Forward-looking statements are based on our current expectations and projections about future events and are subject to risks, uncertainties and assumptions about BHFC and Berkshire, economic and market factors and the industries in which they do business, among other things, that may cause actual events and results to differ materially from the forward-looking statements.

Actual events and results may differ materially from those expressed or forecasted in forward-looking statements due to a number of factors. The principal risk factors that could cause Berkshire’s actual performance and future events and actions to differ materially from such forward-looking statements include, but are not limited to, continuing volatility in the capital or credit markets and other changes in the securities and capital markets, changes in market prices of Berkshire’s investments in fixed maturity and equity securities, losses realized from derivative contracts, the occurrence of one or more catastrophic events, such as an earthquake, hurricane, or act of terrorism that causes losses insured by Berkshire’s insurance subsidiaries, changes in laws or regulations affecting Berkshire’s insurance, railroad, utilities and energy and finance subsidiaries, changes in tax laws (possibly with retroactive effect), and changes in general economic and market factors that affect the prices of securities or the industries in which Berkshire and its affiliates do business. You are advised to consult any additional disclosures Berkshire makes in its Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K filed with the SEC.

Forward-looking statements are not guarantees of future performance. Neither BHFC nor Berkshire undertakes any obligation to update or revise any forward-looking statements to reflect events or developments after the date of this prospectus supplement, except as required by law.

INCORPORATION BY REFERENCE

The information incorporated by reference is considered to be a part of this prospectus from the date Berkshire files that document, and later information filed with the SEC will automatically update and supersede this information.

BHFC and Berkshire incorporate by reference the documents listed below and any future filings made by either of them with the SEC under Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act prior to the termination of any offering of securities made by this prospectus (in each case, excluding any information furnished to, rather than filed with, the SEC, including, but not limited to, information furnished under Items 2.02 or 7.01 of Form 8-K and any corresponding information furnished with respect to such Items under Item 9.01 or as an exhibit):

RISK FACTORS

An investment in our securities involves some degree of risk. Prior to making a decision about investing in our securities, you should carefully consider the risks described in the section entitled “Risk Factors” in any prospectus supplement and the risks described in Berkshire’s most recent Annual Report on Form 10-K filed with the SEC, in each case as these risk factors are amended or supplemented by subsequent Quarterly Reports on Form 10-Q. The occurrence of any of these risks could materially adversely affect our business, operating results and financial condition.

The risks and uncertainties we describe are not the only ones facing us. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business or operations. Any adverse effect on our business, financial condition or operating results could result in a decline in the value of our securities and the loss of all or part of your investment.

There is currently no trading market for the notes and an active trading market for the notes may not develop.

The notes are new issues of securities with no established trading market, and we do not intend to list them on any securities exchange or automated quotation system. As a result, an active trading market for the notes may not develop, or if one does develop, it may not be sustained. If an active trading market fails to develop or cannot be sustained, you may not be able to resell your notes at their fair market value or at all.

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

Our operating businesses are subject to normal economic cycles affecting the economy in general or the industries in which they operate. To the extent that the economy deteriorates for a prolonged period of time, including as a result of tariffs or trade disputes, one or more of our significant operations could be materially harmed. In addition, our utilities and energy businesses and our railroad business regularly utilize debt as a component of their capital structures. These businesses depend on having access to borrowed funds through the capital markets at reasonable rates. To the extent that access to the capital markets is restricted or the cost of funding increases, these operations could be adversely affected.

DESCRIPTION OF THE NOTES AND GUARANTEES

The following description of certain material terms of the notes and the guarantees does not purport to be complete.

This description of the notes and guarantees is intended to be an overview of the material provisions of the notes and the guarantees and is intended to supplement, and to the extent of any inconsistency replace, the description of the general terms and provisions of the debt securities set forth in the accompanying prospectus, to which we refer you. The notes and the guarantees will be issued under an indenture, dated as of January 26, 2016 (the “indenture”), among Berkshire, BHFC and The Bank of New York Mellon Trust Company, N.A., a national banking association, as trustee (the “trustee”). Since this description of the notes and guarantees is only a summary, we urge you to read the indenture (including definitions of terms used therein) and the forms of notes and guarantees because they, and not this description, define your rights as a beneficial owner of the notes. You may request copies of these documents from us at our address set forth above under “Summary—Berkshire Hathaway Finance Corporation.” The indenture and the forms of the notes, including the guarantees to be endorsed thereon, are included or incorporated by reference as an exhibit to the registration statement of which this prospectus supplement forms a part.

General

The notes offered by this prospectus supplement will be issued as a separate series under the indenture. The notes will be our senior unsecured obligations and will be initially limited in aggregate principal amount to $         .

We may at any time, without notice to or consent of the holders of the notes offered by this prospectus supplement, issue additional notes. Any such additional notes will have the same ranking, interest rate, maturity date and other terms as the notes offered hereby, except for possible variations permitted under the indenture. Any such additional notes, together with the notes offered hereby, will constitute a single series of notes under the indenture.

Unless earlier redeemed, the entire principal amount of the notes will mature and become due and payable, together with any accrued and unpaid interest thereon, on                 . The notes will have the benefit of an unconditional and irrevocable guarantee from Berkshire.

The notes will be evidenced by one or more global notes deposited with a custodian for and registered in the name of a nominee of DTC. Except as described herein, beneficial interests in the global notes will be shown on, and transfers thereof will be effected only through, records maintained by DTC and its direct and indirect participants. See “—Book-Entry Delivery and Form.”

You will not have the right to cause us to repurchase the notes in whole or in part at any time before they mature. The notes are not subject to a sinking fund provision.

Interest

The notes will accrue interest at a rate of          % per annum. The notes offered by this prospectus supplement will accrue interest on their stated principal amount from                 , 2018, or from the most recent date to which interest has been paid or duly provided for. Accrued and unpaid interest on the notes will be payable semi-annually in arrears on                  and                  of each year, which we refer to as “interest payment dates,” commencing on                 ,         .

Interest on the notes will be paid to the person in whose name a note is registered at the close of business on the                  and                  (whether or not a business day), which we refer to as “record dates,” immediately preceding the relevant interest payment date.

S-7

The amount of interest payable on the notes for any full semi-annual interest period will be computed on the basis of a 360-day year of twelve 30-day months. The amount of interest payable for any period shorter than a full semi-annual interest period for which interest is computed will be computed on the basis of 30-day months and, for periods of less than a month, the actual number of days elapsed per 30-day month. If any date on which interest is payable on the notes is not a business day, then payment of the interest payable on such date will be made on the next succeeding day that is a business day (and without any interest or other payment in respect of any such delay) with the same force and effect as if made on such interest payment date. For purposes of this prospectus supplement, a “business day” means any day, other than a Saturday or Sunday, that is not a day on which banking institutions in the Borough of Manhattan, The City of New York are authorized or required by law, regulation or executive order to close.

Guarantee of Notes

Berkshire will unconditionally and irrevocably guarantee the payment of all of BHFC’s obligations under the notes offered hereby pursuant to a guarantee to be endorsed on the notes offered hereby, the form of which is included in the indenture, which is filed as an exhibit to the registration statement of which this prospectus forms a part. If we default in the payment of the principal of, or premium, if any, or interest on, such notes when and as the same shall become due, whether upon maturity, acceleration, or otherwise, without the necessity of action by the trustee or any holder of such notes, Berkshire shall be required promptly and fully to make such payment.

Ranking

The notes will be our senior unsecured obligations and will rank pari passu in right of payment with all of our unsubordinated, unsecured indebtedness and will be senior in right of payment to all of our subordinated indebtedness. As of June 30, 2018, BHFC had no secured indebtedness and $8.8 billion of indebtedness.

The guarantees will be senior unsecured obligations of Berkshire, will rank pari passu with all of Berkshire’s unsubordinated, unsecured indebtedness and senior to all of Berkshire’s subordinated indebtedness, and will be effectively subordinated to all of Berkshire’s existing and future secured indebtedness to the extent of the assets securing such indebtedness and structurally subordinated to all existing and future indebtedness of Berkshire’s subsidiaries (secured or unsecured). As of June 30, 2018, Berkshire had no secured indebtedness and $17.8 billion of indebtedness, and its subsidiaries had $79.0 billion of indebtedness.

Optional Redemption

We will have the option to redeem the notes in whole or in part, at any time prior to the Par Call Date, at a redemption price equal to the greater of (A) 100% of the principal amount of the notes to be redeemed or (B) as determined by the quotation agent described below, the sum of the present values of the remaining scheduled payments of principal and interest on the notes to be redeemed that would be due if the notes matured on the Par Call Date, not including any portion of such payments of interest accrued as of the date on which the notes are to be redeemed, discounted to the date on which the notes are to be redeemed on a semi-annual basis assuming a 360-day year consisting of twelve 30-day months, at the adjusted treasury rate described below plus      basis points, plus accrued and unpaid interest on the notes to be redeemed to, but excluding, the date on which such notes are to be redeemed.

At any time on or after the Par Call Date, we may redeem the notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the notes to be redeemed plus accrued and unpaid interest to the date of redemption on the principal amount of the notes being redeemed.

We will utilize the following procedures to calculate the adjusted treasury rate described in the previous paragraph. We will appoint Goldman Sachs & Co. LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and Wells Fargo Securities, LLC or their respective successors, and one or more other primary U.S. Government securities dealers in New York City as reference dealers, and we will appoint Merrill Lynch, Pierce, Fenner & Smith Incorporated or its successor to act as our quotation agent. If any of the foregoing or their respective successors are no longer a primary U.S. Government securities dealer in New York City, we will substitute another primary U.S. Government securities dealer in New York City in its place as a reference dealer.

S-8

The quotation agent will select a United States Treasury security which has a maturity comparable to the remaining maturity of the notes to be redeemed (assuming, for this purpose, that the notes mature on the Par Call Date) which would be used in accordance with customary financial practice to price new issues of corporate debt securities with a maturity comparable to the remaining maturity of such notes (assuming, for this purpose, that the notes mature on the Par Call Date). The reference dealers will provide us with the bid and asked prices for that comparable United States Treasury security as of 5:00 p.m. (New York City time) on the third business day before the redemption date. We will calculate the average of the bid and asked prices provided by each reference dealer, eliminate the highest and the lowest reference dealer quotations and then calculate the average of the remaining reference dealer quotations. However, if we obtain fewer than three reference dealer quotations, we will calculate the average of all the reference dealer quotations and not eliminate any quotations. We call this average quotation the comparable treasury price. The adjusted treasury rate with respect to the notes to be redeemed prior to the Par Call Date will be the semi-annual equivalent yield to maturity of a security whose price is equal to the applicable comparable treasury price, in each case expressed as a percentage of its principal amount.

“Par Call Date” means                      . The Par Call Date is approximately          months prior to the maturity date of the notes.

We may redeem the notes at any time on a redemption date of our choice. However, we must give the holders of such notes notice of the redemption not less than 30 days or more than 60 days before the redemption date. We will give the notice in the manner described under “—Notices.” If we elect to redeem fewer than all the notes, the trustee will select the particular notes to be redeemed by such method that the trustee deems fair and appropriate.

Book-Entry Delivery and Form

General

The notes offered hereby will be issued in registered, global form in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The notes will be issued on the issue date therefor only against payment in immediately available funds.

The notes offered hereby initially will be represented by one or more permanent global certificates (which may be subdivided) in definitive, fully registered form without interest coupons, which we refer to as the “global notes.”

The global notes will be deposited upon issuance with the trustee as custodian for DTC in New York, New York, and registered in the name of DTC or its nominee for credit to an account of a direct or indirect participant in DTC (including the Euroclear Bank S.A./N.V. (“Euroclear”) or Clearstream Banking, société anonyme (“Clearstream”)), as described below under “—Depositary Procedures.”

Except as set forth below, the global notes may be transferred, in whole and not in part, only to DTC, to another nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in the global notes may not be exchanged for notes in certificated form except in the limited circumstances described below under “—Exchange of Book-Entry Notes for Certificated Notes.”

Transfers of beneficial interests in the global notes will be subject to the applicable rules and procedures of DTC and its direct or indirect participants (including, if applicable, those of Euroclear and Clearstream), which may change from time to time.

Depositary Procedures

The following description of the operations and procedures of DTC, Euroclear and Clearstream is provided solely as a matter of convenience. These operations and procedures are solely within the control of the respective settlement systems and are subject to changes by them. We take no responsibility for these operations and procedures and urge investors to contact the systems or their participants directly to discuss these matters.

S-9

DTC is a limited-purpose trust company created to hold securities for its participating organizations, referred to as “participants,” and facilitate the clearance and settlement of transactions in those securities between DTC’s participants through electronic book-entry changes in accounts of its participants. DTC’s participants include securities brokers and dealers (including the underwriters), banks, trust companies, clearing corporations and certain other organizations. Access to DTC’s system is also available to other entities such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a DTC participant, either directly or indirectly, which entities are referred to as “indirect participants.” Persons who are not DTC participants may beneficially own securities held by or on behalf of DTC only through participants or indirect participants. DTC has no knowledge of the identity of beneficial owners of securities held by or on behalf of DTC. DTC’s records reflect only the identity of its participants to whose accounts securities are credited. The ownership interests and transfer of ownership interests of each beneficial owner of each security held by or on behalf of DTC are recorded on the records of DTC’s participants and indirect participants.

Pursuant to procedures established by DTC:

Investors in the global notes may hold their interests therein directly through DTC, if they are participants in such system, or indirectly through organizations (including Euroclear and Clearstream) that are participants or indirect participants in such system. Euroclear and Clearstream will hold interests in the notes on behalf of their participants through customers’ securities accounts in their respective names on the books of their respective depositaries. The depositaries, in turn, will hold interests in the notes in customers’ securities accounts in the depositaries’ names on the books of DTC.

All interests in a global note, including those held through Euroclear or Clearstream, will be subject to the procedures and requirements of DTC. Those interests held through Euroclear or Clearstream will also be subject to the procedures and requirements of these systems. The laws of some jurisdictions require that certain persons take physical delivery of certificates evidencing securities they own. Consequently, the ability to transfer beneficial interests in a global note to such persons will be limited to that extent. Because DTC can act only on behalf of its participants, which in turn act on behalf of indirect participants, the ability of beneficial owners of interests in a global note to pledge such interests to persons or entities that do not participate in the DTC system, or otherwise take actions in respect of such interests, may be affected by the lack of a physical certificate evidencing such interests. For certain other restrictions on the transferability of the notes, see “—Exchange of Book-Entry Notes for Certificated Notes.”

Except as described below, owners of interests in the global notes will not have notes registered in their names, will not receive physical delivery of notes in certificated form and will not be considered the registered owners or holders thereof under the indenture for any purpose.

Payments in respect of the principal of, and interest on, a global note registered in the name of DTC or its nominee will be payable by the trustee (or the paying agent if other than the trustee) to DTC in its capacity as the registered holder under the indenture. We and the trustee will treat the persons in whose names the notes, including the global notes, are registered as the owners thereof for the purpose of receiving such payments and for any and all other purposes whatsoever. Consequently, neither we nor the trustee or any of our respective agents has or will have any responsibility or liability for:

S-10

DTC has advised us that its current practice, upon receipt of any payment in respect of securities such as the notes (including principal and interest), is to credit the accounts of the relevant participants with the payment on the payment date in amounts proportionate to their respective holdings in the principal amount of the relevant security as shown on the records of DTC, unless DTC has reason to believe it will not receive payment on such payment date. Payments by the participants and the indirect participants to the beneficial owners of notes will be governed by standing instructions and customary practices and will be the responsibility of the participants or the indirect participants and will not be the responsibility of DTC, the trustee or us. Neither we nor the trustee will be liable for any delay by DTC or any of its participants in identifying the beneficial owners of the notes, and we and the trustee may conclusively rely on and will be protected in relying on instructions from DTC or its nominee for all purposes.

Transfers between participants in DTC will be effected in accordance with DTC’s procedures, and will be settled in same day funds, and transfers between participants in Euroclear and Clearstream will be effected in accordance with their respective rules and operating procedures.

Cross-market transfers between participants in DTC, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected through DTC in accordance with DTC’s rules on behalf of Euroclear or Clearstream, as the case may be, by their depositaries. Cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in that system in accordance with the rules and procedures and within the established deadlines (Brussels time) of that system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositaries to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant global note in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear and Clearstream participants may not deliver instructions directly to the depositaries for Euroclear or Clearstream.

Because of time zone differences, the securities account of a Euroclear or Clearstream participant purchasing an interest in a global note from a participant in DTC will be credited and reported to the relevant Euroclear or Clearstream participant, during the securities settlement processing day (which must be a business day for Euroclear and Clearstream) immediately following the settlement date of DTC. DTC has advised us that cash received in Euroclear or Clearstream as a result of sales of interests in a global note by or through a Euroclear or Clearstream participant to a participant in DTC will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC’s settlement date.

DTC has advised us that it will take any action permitted to be taken by a holder of notes only at the direction of one or more participants to whose account with DTC interests in the global notes are credited and only in respect of such portion of the aggregate principal amount of the notes as to which such participant or participants has or have given such direction.

Although DTC, Euroclear and Clearstream have agreed to the foregoing procedures to facilitate transfers of interests in the global notes among participants in DTC, Euroclear and Clearstream, they are under no obligation to perform or to continue to perform such procedures, and the procedures may be discontinued at any time. None of us, Berkshire or the trustee will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

The information in this section concerning DTC, Euroclear and Clearstream and their book-entry systems has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy thereof.

S-11

Exchange of Book-Entry Notes for Certificated Notes

The global notes are exchangeable for certificated notes in definitive, fully registered form without interest coupons only in the following limited circumstances:

In all cases, certificated notes delivered in exchange for any global note or beneficial interests therein will be registered in the names, and issued in any approved denominations, requested by or on behalf of DTC (in accordance with its customary procedures).

Notices

Except as otherwise described herein, notice to registered holders of the notes will be given by mail to the addresses as they appear in the security register. Notices will be deemed to have been given on the date of such mailing.

S-12

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of certain U.S. federal income tax considerations that may be relevant to initial holders of the notes. The summary is limited to holders that purchase notes in the initial offering for cash at their initial offering price and that hold the notes as capital assets within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”), which generally means as property held for investment. The summary does not purport to address all of the tax considerations that may be relevant to a particular holder or to deal with the tax considerations that may be relevant to holders in special tax situations, such as banks, thrifts, real estate investment trusts, regulated investment companies, partnerships and other pass-through entities, insurance companies, dealers in securities or currencies, traders in securities electing to use a mark-to-market method of accounting, accrual basis taxpayers subject to special tax accounting rules under Section 451(b) of the Code, foreign persons (except to the extent specifically provided below), tax-exempt organizations, United States expatriates and certain former citizens or long-term residents of the United States, persons holding notes as part of a straddle, hedge, conversion transaction, “synthetic security” or other integrated investment, persons deemed to sell the notes under the constructive sale provisions of the Code, or U.S. holders (as defined below) whose “functional currency” is not the U.S. dollar, nor does it address federal estate, gift or alternative minimum taxes or state, local, or foreign taxes.

If a partnership (including any entity treated as a partnership for U.S. federal income tax purposes) or pass-through entity holds notes, the tax treatment of a partner or a member in that partnership or pass-through entity generally will depend upon the status of the partner or the member and upon the activities of the partnership or pass-through entity. A partnership or pass-through entity considering a purchase of the notes, and partners or members in such a partnership or pass-through entity, should consult their own tax advisors regarding the tax consequences to them of the purchase, ownership and disposition of the notes.

This summary is based upon the Code, Treasury regulations, Internal Revenue Service (“IRS”) rulings and pronouncements and administrative and judicial decisions currently in effect, all of which are subject to change (possibly with retroactive effect) or possible differing interpretations. No ruling has been or will be sought from the IRS with respect to the U.S. federal income tax consequences of the purchase, ownership and disposition of the notes. As a result, the IRS could disagree with portions of this discussion.

This discussion is for general purposes only. Persons considering a purchase of the notes should consult their own tax advisors with respect to the tax consequences to them of the purchase, ownership and disposition of the notes in light of their own particular circumstances, including the tax consequences under federal, state, local and foreign tax laws and tax treaties and the possible effects of any changes in applicable tax laws.

Payments Under Certain Events

Under the terms of the notes, we may be obligated in certain circumstances to pay amounts in excess of stated interest or principal on the notes. It is possible that the IRS could assert that the payment of such excess amounts is a “contingent payment” and the notes are therefore contingent payment debt instruments for U.S. federal income tax purposes. Under the applicable Treasury regulations, however, for purposes of determining whether a debt instrument is a contingent payment debt instrument, remote or incidental contingencies (determined as of the date the notes are issued) are ignored. Although the issue is not free from doubt, we believe that the possibility of making additional payments is remote and/or incidental. Accordingly, we do not intend to treat the notes as contingent payment debt instruments. Our position will be binding on holders of the notes, unless a holder timely and explicitly discloses to the IRS that it takes a position different from ours. Our position, however, is not binding on the IRS. If the IRS successfully challenges this position, the timing and amount of income included and the character of the income recognized with respect to the notes may be materially different from the consequences discussed herein. Holders should consult their own tax advisors regarding the tax consequences of the notes being treated as contingent payment debt instruments. The remainder of this discussion assumes that the notes are not treated as contingent payment debt instruments.

S-13

Consequences to U.S. Holders

The following discussion summarizes certain U.S. federal income tax considerations relevant to a U.S. holder. For purposes of this discussion, the term “U.S. holder” means a beneficial owner of the notes that is (1) an individual who is a citizen or resident of the United States, (2) a corporation or other entity treated as a corporation for U.S. federal income tax purposes, in each case, that is created or organized in or under the laws of the United States, any state thereof or the District of Columbia, (3) a trust if it (i) is subject to the primary supervision of a U.S. court and the control of one or more United States persons (as defined in the Code) or (ii) has a valid election in effect under applicable Treasury regulations to be treated as a United States person (as defined in the Code), or (4) an estate, the income of which is subject to U.S. federal income tax regardless of its source.

Payments or Accruals of Interest

Payments or accruals of interest on a note will be taxable to U.S. holders as ordinary interest income at the time such U.S. holders receive or accrue such amounts (in accordance with a holder’s regular method of tax accounting).

Sale, Exchange, Redemption or Other Disposition of the Notes

When a U.S. holder disposes of a note by sale, exchange, redemption or other disposition, the holder will generally recognize gain or loss equal to the difference between the amount the holder realizes on the transaction (less any amount attributable to accrued and unpaid interest, which will be taxable as such) and the holder’s adjusted tax basis in the note. A U.S. holder’s adjusted tax basis in a note will generally equal the cost of the note to the holder.

The gain or loss that a U.S. holder recognizes on the sale, exchange, redemption or other disposition of a note will generally be capital gain or loss and will be long-term capital gain or loss if the holder held the note for more than one year on the date of disposition. Long-term capital gains recognized by non-corporate U.S. holders (including individuals) are subject to taxation at preferential rates. The tax deductibility of capital losses is subject to limitations.

3.8% Medicare Tax On “Net Investment Income”

U.S. holders that are individuals, estates, and certain trusts are subject to an additional 3.8% Medicare tax on the lesser of (a) such holder’s “net investment income” (or undistributed “net investment income” in the case of an estate or trust) for the relevant taxable year and (b) the excess of the U.S. holder’s modified gross income for the taxable year over certain thresholds (generally $200,000 for an unmarried individual, $250,000 for a married taxpayer filing a joint return (or a surviving spouse), or $125,000 for a married individual filing a separate return). Net investment income will generally include interest income and net gains from the disposition of the notes, unless such interest income or net gains are derived in the ordinary course of the conduct of a trade or business (other than a trade or business that consists of certain passive or trading activities). U.S. holders should consult their advisors with respect to their consequences with respect to the 3.8% Medicare tax.

Backup Withholding and Information Reporting

Unless a U.S. holder is an exempt recipient, payments under the notes or proceeds received from the sale of the notes will generally be subject to information reporting and will generally also be subject to U.S. federal backup withholding tax if such U.S. holder fails to supply an accurate taxpayer identification number or otherwise fails to comply with applicable U.S. information reporting or certification requirements. Any amounts so withheld do not constitute a separate tax and will generally be allowed as a refund or a credit against the U.S. holder’s U.S. federal income tax liability, provided that the required information is timely furnished to the IRS.

S-14

Consequences to Non-U.S. Holders

The following discussion summarizes certain U.S. federal income tax considerations relevant to a non-U.S. holder. For purposes of this discussion, the term “non-U.S. holder” means a beneficial owner of the notes that for U.S. federal income tax purposes is a nonresident alien individual, a foreign corporation, or a trust or estate that is not a U.S. holder.

Payments of Interest

Subject to the discussions below under “—Backup Withholding and Information Reporting” and “—Foreign Account Tax Compliance Act”, payments of interest on the notes made to a non-U.S. holder will generally be exempt from U.S. federal income and withholding tax, provided that:

If a non-U.S. holder cannot satisfy the requirements described above, payments of interest made to such non-U.S. holder will be subject to a 30% U.S. federal withholding tax, unless such non-U.S. holder provides the applicable withholding agent with a properly executed:

If payments of interest on the notes are effectively connected with the conduct by a non-U.S. holder of a trade or business in the United States (and, where an income tax treaty applies, are attributable to a United States permanent establishment), then such non-U.S. holder will be subject to U.S. federal income tax on such interest payments on a net income basis in the same manner as a U.S. holder (but without regard to the 3.8% Medicare tax, described above), although such non-U.S. holder will be exempt from the 30% U.S. federal withholding tax if the certification requirements discussed above are satisfied. In addition, a non-U.S holder that is a foreign corporation may be subject to an additional branch profits tax equal to 30% (or lower applicable tax treaty rate) of such interest, subject to adjustments.

S-15

Sale, Exchange, Redemption or Other Disposition of the Notes

Subject to the discussions below under “—Backup Withholding and Information Reporting” and “—Foreign Account Tax Compliance Act”, any gain realized by a non-U.S. holder upon a sale, exchange, redemption or other disposition of the notes will generally not be subject to U.S. federal income tax, unless:

Any gain realized by a non-U.S. holder upon a sale, exchange, redemption or other disposition of the notes that is effectively connected with the conduct by the non-U.S. holder of a trade or business in the United States (and, where an income tax treaty applies, is attributable to a United States permanent establishment) will generally be taxable as discussed above with respect to effectively connected interest on the notes. If a non-U.S. holder is subject to U.S. federal income tax because the non-U.S. holder is an individual who is present in the United States for 183 days or more in the taxable year of the disposition, any gain realized by the non-U.S. holder on the sale, exchange, redemption or other disposition of the notes that is not effectively connected with the conduct by the non-U.S. holder of a trade or business in the United States will be subject to a flat 30% tax on the gain derived from such disposition (or lower applicable tax treaty rate), which gain may be offset by United States-source capital losses.

Backup Withholding and Information Reporting

Generally, information reporting will apply to the amount of interest paid to each non-U.S. holder and the amount of tax, if any, withheld with respect to those payments. These reporting requirements apply regardless of whether withholding is reduced or eliminated by the Code or an applicable income tax treaty or otherwise. Copies of the information returns reporting such interest payments and any withholding may also be made available to the tax authorities in the country in which a non-U.S. holder resides under the provisions of an applicable tax treaty or agreement.

In general, a non-U.S. holder will not be subject to U.S. federal backup withholding with respect to payments of interest on the notes if the non-U.S. holder provides an IRS Form W-8BEN or Form W-8BEN-E (or a successor form) with respect to such payments or otherwise satisfies applicable documentation requirements. In addition, no information reporting or backup withholding will generally be required with respect to the proceeds of a sale or other disposition of the notes by a non-U.S. holder made within the United States or conducted through certain United States-related financial intermediaries if the payor receives such a form or the non-U.S. holder otherwise establishes an exemption.

Backup withholding is not an additional tax and any amounts so withheld will generally be allowed as a refund or a credit against the non-U.S. holder’s U.S. federal income tax liability, provided that the required information is timely furnished to the IRS.

Foreign Account Tax Compliance Act

Withholding taxes may be imposed under Sections 1471 to 1474 of the Code (such Sections commonly referred to as the Foreign Account Tax Compliance Act, or “FATCA”) on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on payments of interest on, or gross proceeds from the sale or other disposition of, a note paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in the Code), unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) the non-financial foreign

S-16

entity either certifies it does not have any “substantial United States owners” (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain “specified United States persons” or “United States owned foreign entities” (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

Withholding under FATCA generally will apply to payments of interest on a note regardless of when they are made. However, under the applicable Treasury regulations and IRS guidance, withholding under FATCA generally will only apply to payments of gross proceeds from the sale or other disposition of a note on or after January 1, 2019. Prospective investors should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in the notes.

S-17

UNDERWRITING

BHFC and Berkshire have entered into an underwriting agreement with Goldman Sachs & Co. LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and Wells Fargo Securities, LLC with respect to the notes. Subject to certain conditions, we have agreed to sell to each underwriter and each underwriter named below has severally agreed to purchase from us the principal amount of the notes that appears opposite its name in the table below.

The underwriters have agreed to purchase all of the notes if any of them are purchased. The underwriting agreement provides that the obligations of the underwriters to purchase the notes included in this offering are subject to, among other customary conditions, the delivery of certain legal opinions by their counsel. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non- defaulting underwriters may also be increased or the offering may be terminated.

The underwriters initially propose to offer the notes to the public at the public offering price that appears on the cover page of this prospectus supplement. The underwriters may offer the notes to selected dealers at the public offering price minus a concession of up to         % of the principal amount of the notes. In addition, the underwriters may allow, and those selected dealers may reallow, a concession of up to        % of the principal amount of the notes to certain other dealers. After the initial offering, the underwriters may change the public offering price and any other selling terms. The underwriters may offer and sell notes through certain of their affiliates. The offering of the notes by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

In the underwriting agreement, we have agreed that, subject to certain exceptions, we will indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act, or contribute to payments that the underwriters may be required to make in respect of those liabilities.

The following table shows the underwriting discounts that we will pay to the underwriters in connection with this offering of notes:

We estimate that we will spend approximately $         million for printing, rating agency fees, trustee and legal fees and other expenses related to this offering.

The notes are new issues of securities with no established trading market. We do not intend to apply for the notes to be listed on any securities exchange or to arrange for the notes to be quoted on any quotation system. The underwriters have advised us that they intend to make a market in the notes. However, they are not obligated to do so and may discontinue any market making at any time in their sole discretion. Therefore, we cannot assure you that a liquid trading market will develop for the notes, that you will be able to sell your notes at a particular time or that the prices that you receive when you sell will be favorable.

S-18

In connection with the offering, the underwriters may engage in overallotment, stabilizing transactions and syndicate covering transactions. Overallotment involves sales in excess of the offering size, which creates a short position for the underwriters. Stabilizing transactions involve bids to purchase the notes in the open market for the purpose of pegging, fixing or maintaining the price of the notes. Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover short positions. Stabilizing transactions and syndicate covering transactions may cause the price of the notes to be higher than it would otherwise be in the absence of those transactions. If the underwriters engage in stabilizing or syndicate covering transactions, they may discontinue them at any time. The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the underwriters have repurchased notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

Each underwriter and its affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. Each underwriter and certain of its affiliates have, from time to time, performed, and may in the future perform, various financial advisory and investment banking services for Berkshire and BHFC, for which they have received or will receive customary fees and expenses reimbursements. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

In the ordinary course of their various business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and/or instruments of the issuer or its affiliates. If any of the underwriters or their affiliates has a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby.

We expect that delivery of the notes will be made against payment therefor on or about                     , 2018, which is the          business day following the date of this prospectus supplement (such settlement cycle being referred to as “T+        ”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in two business days unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on any date prior to the second business day before delivery hereunder will be required, by virtue of the fact that the notes initially will settle in T+        , to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes prior to the second business day before their date of delivery hereunder should consult their own advisors.

Offering Restrictions

Any resale of the notes must be made in accordance with an exemption from, or in a transaction not subject to, the prospectus requirements of applicable securities laws.

S-19

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if this prospectus supplement (including any amendment thereto) contains a misrepresentation, provided that the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser’s province or territory. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for particulars of these rights or consult with a legal advisor.

Pursuant to section 3A.3 of National Instrument 33-105 Underwriting Conflicts (NI 33-105), the underwriters are not required to comply with the disclosure requirements of NI 33-105 regarding underwriter conflicts of interest in connection with this offering.

PRIIPs Regulation / Prospectus Directive / Prohibition of sales to EEA retail investors

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); or (ii) a customer within the meaning of Directive 2002/92/EC (as amended, the “Insurance Mediation Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Directive 2003/71/EC (as amended, the “Prospectus Directive”). Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared, and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation. This prospectus supplement has been prepared on the basis that any offer of notes in any Member State of the EEA will be made pursuant to an exemption under the Prospectus Directive from the requirement to publish a prospectus for offers of notes. This prospectus supplement and the underlying prospectus are not a prospectus for the purposes of the Prospectus Directive.
