6.75% Notes Due 2013


         We are offering to exchange up to $500,000,000 of our new 6.75% Notes due 2013 (the "exchange notes"), which will be registered under the Securities Act of 1933, as amended (the "Securities Act"), for any and all of our outstanding 6.75% Notes due 2013 (the "outstanding notes").

The Exchange Notes

Resales of the Exchange Notes

         All untendered outstanding notes will continue to be subject to the restrictions on transfer set forth in the outstanding notes and in the related indenture and first supplemental indenture thereto (collectively, the "indenture"). In general, the outstanding notes may not be offered or sold, unless registered under the Securities Act, except pursuant to an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. Other than in connection with the exchange offer, we currently do not anticipate that we will register the outstanding notes under the Securities Act.

The letter of transmittal states that by so acknowledging and delivering a prospectus, a broker-dealer will not be deemed to admit that it is an "underwriter" within the meaning of the Securities Act.

         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 outstanding notes where the broker-dealer acquired such outstanding notes as a result of market-making or other trading activities.

         Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these notes or passed upon the adequacy or accuracy of this prospectus. Any representation to the contrary is a criminal offense.

The date of this prospectus is                    , 2008.

Best Buy Co., Inc.

Overview

        We are a specialty retailer of consumer electronics, home office products, entertainment software, appliances and related services. We operate retail stores and Web sites under the brand names Best Buy, Best Buy Mobile, The Carphone Warehouse, Jiangsu Five Star Appliance Co. ("Five Star"), Future Shop, Geek Squad, Magnolia Audio Video, Pacific Sales Kitchen and Bath Centers ("Pacific Sales"), The Phone House and Speakeasy.

        Our vision is to make life fun and easy for consumers. Our business strategy is to treat customers as unique individuals, meeting their needs with end-to-end solutions, and engaging and energizing our employees to serve them, while maximizing overall profitability. We believe we offer consumers meaningful advantages in store environment, product value, product selection and a variety of in-store and in-home services related to the merchandise we offer, all of which advance our objectives of enhancing our business model, gaining market share and improving profitability.

        We operate two reportable segments: Domestic and International. The Domestic segment is comprised of all states, districts and territories of the U.S. and includes store, call center and online operations, including Best Buy, Best Buy Mobile, Geek Squad, Magnolia Audio Video, Pacific Sales and Speakeasy. U.S. Best Buy stores offer a wide variety of consumer electronics, home office products, entertainment software, appliances and related services. The International segment is comprised of all Canada stores, call centers and online operations, including Best Buy, Future Shop and Geek Squad, as well as all China stores, call centers and online operations, including Best Buy, Geek Squad and Five Star. Our International segment offers products and services similar to that of our U.S. Best Buy stores. However, Canada Best Buy stores do not carry appliances, and our China Best Buy store and Five Star stores do not carry entertainment software. Since June 30, 2008, our International segment has also included Best Buy Europe as described below under "—Best Buy Europe Acquisition."

        The addition of new stores has played, and we believe will continue to play, a significant role in our growth and success. Our store development program has historically focused on entering new markets; adding stores within existing markets; and relocating, remodeling and expanding existing stores in order to offer new products and services to our customers. During fiscal 2008, we opened 155 new stores, relocated nine stores and closed 18 stores.

        During fiscal 2009, we anticipate opening approximately 125 new stores in the U.S., Canada, China and Mexico. Most of the new stores will be opened in markets where we already have stores, leveraging our infrastructure and making shopping more convenient for our customers. In the U.S., we anticipate opening 85 to 100 new Best Buy stores, as well as relocating four existing Best Buy stores. In Canada, we anticipate opening approximately six Future Shop stores and six Best Buy stores, as well as to relocate four existing Future Shop stores. In China, we plan to open eight to 16 Five Star stores, as well as close one Five Star store. We also anticipate opening one to three additional Best Buy stores in China in fiscal 2009. Finally, we anticipate extending our international presence by opening our first two stores in Mexico in fiscal 2009 and our first one or two stores in Turkey in the first half of fiscal 2010.

        We believe our store experience, broad product assortment, store formats and brand marketing strategies differentiate us from most of our competitors by positioning our stores as the preferred destination for new technology and entertainment products in a fun and informative shopping environment. Our stores compete by aggressively advertising and emphasizing a complete product and service solution, value pricing and financing alternatives. In addition, our trained and knowledgeable sales and service staffs allow us to tailor the offerings to meet the needs of our customers.

Best Buy Europe Acquisition

        On June 30, 2008, pursuant to a Sale and Purchase Agreement (the "Sale and Purchase Agreement") dated as of May 7, 2008, among The Carphone Warehouse Group PLC ("The Carphone Warehouse"); CPW Retail Holdings Limited ("CPW Retail"), a wholly-owned subsidiary of The Carphone Warehouse; Best Buy Distributions Limited ("BBY Acquisition Co."), our wholly-owned subsidiary; and us, The Carphone Warehouse and CPW Retail contributed certain assets and liabilities into Best Buy Europe Distributions Limited, formerly known as Best Buy International Limited ("Best Buy Europe"), a company registered in England and Wales, in exchange for all of the ordinary shares of Best Buy Europe. Immediately thereafter, BBY Acquisition Co. purchased 50% of the ordinary shares of Best Buy Europe from The Carphone Warehouse for an aggregate purchase price of £1.088 billion (approximately $2.167 billion). In addition to the purchase price, we incurred $29 million of transaction costs, for an aggregate purchase price of approximately $2.196 billion. We funded the payment of the purchase price and related transaction costs with cash-on-hand, through additional borrowings available under our existing credit facilities and with proceeds from the sale of the outstanding notes. We refer to the transactions contemplated by the Sale and Purchase Agreement as the "Best Buy Europe Acquisition." The effective acquisition date for accounting purposes was the close of business on June 28, 2008, the end of The Carphone Warehouse's fiscal first quarter.

        Solely for the convenience of the reader, we have translated the purchase price from British pounds sterling into U.S. dollars using the exchange rate of £1.00 = $1.99, which was the rate on June 30, 2008. This translation should not be considered a representation that such amount was, could have been or could be converted into U.S. dollars at that or at any other exchange rate.

        The assets and liabilities transferred by The Carphone Warehouse and CPW Retail to Best Buy Europe comprise all of The Carphone Warehouse's mobile and retail distribution businesses, consisting primarily of the sale of mobile handsets and connections, laptop computers, accessories and related products and services. The Carphone Warehouse sold these products and services through 2,411 stores, call centers and the Internet across Europe, branded The Carphone Warehouse in the U.K. and The Phone House outside the U.K. The Carphone Warehouse also transferred to Best Buy Europe its device insurance business and certain revenue-sharing agreements. In addition, the assets and liabilities that were transferred to Best Buy Europe include The Phone House Telecom, a mobile service provider business in Germany that recruits, bills and manages customers on its own mobile packages, and The Carphone Warehouse's mobile virtual network operator businesses. The Carphone Warehouse further transferred portions of its fixed line businesses, which consist of the sale of fixed line services in Spain via Xtra Telecom and re-sale of residential fixed line services in Switzerland. The businesses transferred to Best Buy Europe also include The Carphone Warehouse's facilities management business and its dealer business. Finally, The Carphone Warehouse transferred to Best Buy Europe its economic interest in its existing relationships with Best Buy (currently consisting of Best Buy Mobile in the U.S. and Geek Squad in the U.K. and Spain).

        We and The Carphone Warehouse plan to introduce new offerings in the retail stores contributed to Best Buy Europe by The Carphone Warehouse and launch large-format Best Buy-branded stores and Web sites in the European market. From the date of acquisition to the end of fiscal 2009, Best Buy Europe plans to open 90 to 100 new stores, as well as to close 60 to 65 stores branded The Carphone

Warehouse or The Phone House. In addition, we anticipate opening our first one to three Best Buy stores in the U.K. in fiscal 2010.

Napster Acquisition

        On September 14, 2008, we and our wholly-owned subsidiary, Puma Cat Acquisition Corp., a Delaware corporation ("Puma Cat"), entered into an Agreement and Plan of Merger (the "Merger Agreement") with Napster, Inc., a Delaware corporation ("Napster"). The total transaction value is expected to be approximately $121 million (or approximately $54 million, net of $67 million in cash and short-term investments of Napster as of June 30, 2008).

        Pursuant to the Merger Agreement, and subject to the conditions set forth therein, Puma Cat commenced a cash tender offer on September 26, 2008 to acquire all of the issued and outstanding shares of Napster's common stock, and all stock purchase rights associated with such shares, at a price of $2.65 per share, without any interest or accrued dividends, net to the seller. The tender offer expired on October 24, 2008. Approximately 83% of the outstanding shares of Napster's common stock was validly tendered and not withdrawn prior to the expiration of the offer. On October 27, 2008, Puma Cat began a subsequent offering period for all of the remaining outstanding and untendered shares of Napster's common stock for the same consideration paid in respect of the shares tendered during the initial offering period. The subsequent offering period expired on October 29, 2008. An additional 8% of the outstanding shares of Napster's common stock was validly tendered and not withdrawn during the subsequent offering period. Puma Cat accepted for purchase all validly tendered shares in accordance with the terms of the offer and promptly paid the aggregate purchase price of approximately $104.5 million for the shares tendered pursuant to the offer (including the subsequent offering period).

        Following the purchase of shares pursuant to the initial cash tender offer, we beneficially owned more than 50% of the outstanding shares of Napster's common stock on a fully-diluted basis. As a result, we had the power to assure the consummation of the proposed merger of Puma Cat into Napster by voting the shares beneficially owned by us at a special meeting of the stockholders of Napster. In addition, under the terms of the Merger Agreement, we exercised an option to purchase newly-issued Napster shares at the tender offer price. Because we acquired beneficial ownership of more than 90% of the outstanding shares of Napster's common stock as a result of the exercise of our option to purchase newly-issued shares, we caused Puma Cat to merge into Napster without a meeting of the stockholders of Napster pursuant to the "short-form" merger statute under Delaware law. As a result of the merger, with certain exceptions, each outstanding share of common stock of Napster was converted into the right to receive $2.65 per share, in cash, without interest. This process has resulted in our ownership of 100% of Napster's common stock.


        Best Buy Co., Inc. is a Minnesota corporation whose principal executive offices are located at 7601 Penn Avenue South, Richfield, Minnesota 55423. Our main telephone number is 612-291-1000.

The Exchange Offer

        On June 24, 2008, we issued and sold $500,000,000 aggregate principal amount of the outstanding notes in a transaction exempt from registration under the Securities Act. In this prospectus, the term "outstanding notes" refers to our 6.75% Notes due 2013, as issued and sold on that date. The term "exchange notes" refers to our 6.75% Notes due 2013, as registered under the Securities Act. The term "notes" refers, collectively, to the outstanding notes and the exchange notes.

        The summary below describes the principal terms of the exchange offer. The section of this prospectus titled "The Exchange Offer" contains a more detailed description of the terms and conditions of the exchange offer.

General

  In connection with the offering of the outstanding notes, we entered into a registration rights agreement with the initial purchasers in which we agreed, among other things, to use our reasonable best efforts to complete the exchange offer by January 31, 2009.

 

You are entitled to exchange in the exchange offer your outstanding notes for exchange notes, which are identical in all material respects to the outstanding notes except as follows:

 

 

the exchange notes have been registered under the Securities Act;

 

 

the exchange notes are not entitled to any registration rights that are applicable to the outstanding notes under the registration rights agreement; and

 

 

the additional interest provisions are no longer applicable.

The Exchange Offer

 

We are offering to exchange up to $500,000,000 aggregate principal amount of our 6.75% Notes due 2013, which have been registered under the Securities Act, for any and all of our outstanding 6.75% Notes due 2013.

 

You may only exchange outstanding notes in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

 

Subject to the satisfaction or waiver of specified conditions, we will exchange the exchange notes for all outstanding notes that are validly tendered and not validly withdrawn prior to the expiration of the exchange offer. We will cause the exchange to be effected promptly after the expiration of the exchange offer.

4


Resale

 

Based on interpretations by the staff of the SEC set forth in no-action letters issued to third parties, we believe that the exchange notes issued pursuant to the exchange offer in exchange for outstanding notes may be offered for resale, resold and otherwise transferred by you (unless you are our "affiliate" within the meaning of Rule 405 under the Securities Act) without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that:

 

 

you are acquiring the exchange notes in the ordinary course of your business; and

 

 

you have not engaged in, do not intend to engage in, and have no arrangement or understanding with any person to participate in, a distribution of the exchange notes.

 

If you are a broker-dealer and receive exchange notes for your own account in exchange for outstanding notes that you acquired as a result of market-making activities or other trading activities, you must acknowledge that you will deliver this prospectus in connection with any resale of the exchange notes. See "Plan of Distribution."

Expiration Date

 

The exchange offer expires at                     p.m. (New York City time) on                    , 2009, unless extended by us. We do not currently intend to extend the expiration date.

Withdrawal

 

You may withdraw any tender of your outstanding notes at any time prior to the expiration of the exchange offer. We will return to you any of your outstanding notes that are not accepted for any reason for exchange, without expense to you, promptly after the expiration or termination of the exchange offer.

Interest on the Exchange Notes and the Outstanding Notes

 

Each exchange note bears interest at the rate of 6.75% per annum from the original issuance date of the outstanding notes or from the most recent date on which interest has been paid on the notes. The interest on the notes is payable on January 15 and July 15 of each year, beginning on January 15, 2009. No interest will be paid on outstanding notes following their acceptance for exchange.

Conditions to the Exchange Offer

 

The exchange offer is subject to customary conditions, which we may assert or waive. See "The Exchange Offer—Conditions to the Exchange Offer."

Procedures for Tendering Outstanding Notes

 

If you wish to participate in the exchange offer, you must complete, sign and date the accompanying letter of transmittal, or a facsimile of the letter of transmittal, according to the instructions contained in this prospectus and the letter of transmittal. You must then mail or otherwise deliver the letter of transmittal, or a facsimile of the letter of transmittal, together with the outstanding notes and any other required documents, to the exchange agent at the address set forth on the cover page of the letter of transmittal.

5


 

If you hold outstanding notes through The Depository Trust Company ("DTC") and wish to participate in the exchange offer, you must comply with the procedures under DTC's Automated Tender Offer Program by which you will agree to be bound by the letter of transmittal. By signing, or agreeing to be bound by, the letter of transmittal, you will represent to us that, among other things:

 

 

you do not have arrangement or understanding with any person or entity to participate in a distribution of the exchange notes;

 

 

you are not our "affiliate" within the meaning of Rule 405 under the Securities Act;

 

 

you are not engaged in, and do not intend to engage in, a distribution of the exchange notes;

 

 

you are acquiring the exchange notes in the ordinary course of your business; and

 

 

if you are a broker-dealer that receives exchange notes for your own account in exchange for outstanding notes that were acquired as a result of market-making activities, that you will deliver a prospectus, as required by law, in connection with any resale of such exchange notes.

Special Procedures for Beneficial Owners

 

If you are a beneficial owner of outstanding notes that are held in the name of a broker, dealer, commercial bank, trust company or other nominee, and you wish to tender those outstanding notes in the exchange offer, you should contact the registered holder promptly and instruct the registered holder to tender those outstanding notes on your behalf. If you wish to tender on your own behalf, you must, prior to completing and executing the letter of transmittal and delivering your outstanding notes, either make appropriate arrangements to register ownership of the outstanding notes in your name or obtain a properly completed bond power from the registered holder. The transfer of registered ownership may take considerable time and may not be able to be completed prior to the expiration date.

Guaranteed Delivery Procedures

 

If you wish to tender your outstanding notes and your outstanding notes are not immediately available or you cannot deliver your outstanding notes, the letter of transmittal or any other required documents, or you cannot comply with the procedures under DTC's Automated Tender Offer Program for transfer of book-entry interests, prior to the expiration date, you must tender your outstanding notes according to the guaranteed delivery procedures described under "The Exchange Offer—Guaranteed Delivery Procedures."

Effect on Holders of Outstanding Notes

 

As a result of the making of, and upon acceptance for exchange of all validly tendered outstanding notes pursuant to the terms of, the exchange offer, we will have fulfilled a covenant under the registration rights agreement. Accordingly, there will be no increase in the interest rate on the outstanding notes under the circumstances described in the registration rights agreement. If you do not tender your outstanding notes in the exchange offer, you will continue to be entitled to all the rights and limitations applicable to the outstanding notes as set forth in the indenture, except we will not have any further obligation to you to provide for the exchange and registration of the outstanding notes under the registration rights agreement. To the extent that outstanding notes are tendered and accepted in the exchange offer, the trading market for outstanding notes could be adversely affected.

Consequences of Failure to
Exchange

 

All untendered outstanding notes will continue to be subject to the restrictions on transfer set forth in the outstanding notes and in the indenture. In general, the outstanding notes may not be offered or sold, unless registered under the Securities Act, except pursuant to an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. Other than in connection with the exchange offer, we do not anticipate that we will register the outstanding notes under the Securities Act.

U.S. Federal Income Tax Consequences of the Exchange Offer

 

The exchange of outstanding notes for exchange notes in the exchange offer will not be a taxable event for U.S. federal income tax purposes. See "Certain U.S. Federal Income Tax Consequences of the Exchange Offer."

Use of Proceeds

 

We will not receive any cash proceeds from the issuance of exchange notes in the exchange offer. See "Use of Proceeds."

Exchange Agent

 

Wells Fargo Bank, N.A. is the exchange agent for the exchange offer. The addresses and telephone numbers of the exchange agent are set forth under "The Exchange Offer—Exchange Agent."

The exchange notes will be issued in book-entry form and will be represented by global certificates deposited with, or on behalf of, DTC and registered in the name of Cede & Co., DTC's nominee. Beneficial interests in the exchange notes will be shown on, and transfers will be effected only through, records maintained by DTC or its nominee; and these interests may not be exchanged for certificated notes, except in limited circumstances. See "Description of the Notes—Global Notes; Book-Entry System."

No Listing

 

The exchange notes are not listed on any securities exchange or market.

Risk Factors

 

You should carefully consider all of the information included and incorporated by reference in this prospectus. See "Risk Factors" included in this prospectus and Part I, Item 1A., "Risk Factors" and Part II, Item 7., "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the fiscal year ended March 1, 2008 (our "Fiscal 2008 Form 10-K"), which is incorporated by reference in this prospectus. In addition, you should review the information set forth under "Forward-Looking and Cautionary Statements" before deciding to tender your outstanding notes in the exchange offer.

RISK FACTORS

        Before deciding to tender your outstanding notes in the exchange offer, you should consider the risk factors below as well as the risk factors discussed in Part I, Item 1A., "Risk Factors," and Part II, Item 7., "Management's Discussion and Analysis of Financial Condition and Results of Operations," in our Fiscal 2008 Form 10-K, which is incorporated by reference in this prospectus. See "Incorporation of Certain Documents by Reference." Any of the following risks could materially and adversely affect our business, financial condition or results of operations. Additional risks and uncertainties not currently known to us or those we currently view to be immaterial may also materially and adversely affect our business, financial condition or results of operations. In that case, the market price of our exchange notes could decline and you could lose all or part of your investment.

Risks Relating to the Exchange Offer

If you do not exchange your outstanding notes in the exchange offer, the transfer restrictions currently applicable to your outstanding notes will remain in force and the market price of your outstanding notes could decline.

        If you do not exchange your outstanding notes for exchange notes in the exchange offer, then you will continue to be subject to the transfer restrictions on the outstanding notes as set forth in the offering memorandum distributed in connection with the private offering of the outstanding notes. In general, the outstanding notes may not be offered or sold unless they are registered, or exempt from registration, under the Securities Act and applicable state securities laws (including pursuant to Rule 144 under the Securities Act, as and when available). Except as required by the registration rights agreement, we do not intend to register resales of the outstanding notes under the Securities Act.

        The tender of outstanding notes under the exchange offer will reduce the aggregate principal amount of the outstanding notes, which may have an adverse effect upon, and increase the volatility of, the market prices of the outstanding notes due to reduction in liquidity. In addition, if you do not exchange your outstanding notes in the exchange offer, you will no longer be entitled to exchange your outstanding notes for exchange notes registered under the Securities Act and you will no longer be entitled to have your outstanding notes registered for resale under the Securities Act.

Your ability to transfer the exchange notes may be limited by the absence of an active trading market, and there is no assurance that any active trading market will develop for the exchange notes.

        We do not intend to apply for listing of the exchange notes on a securities exchange or market. The exchange notes are a new issue of securities for which there is no established public market. The initial purchasers in the private offering of the outstanding notes have advised us that they intend to make a market in the exchange notes as permitted by applicable laws and regulations; however, the initial purchasers are not obligated to make a market in any of the exchange notes, and they may discontinue their market-making activities at any time without notice. In addition, such market-making activity may be limited during the pendency of the exchange offer. Therefore, an active market for any of the exchange notes may not develop or, if developed, it may not continue. In addition, subsequent to their initial issuance, the exchange notes may trade at a discount from their initial offering price, depending upon prevailing interest rates, the market for similar notes, our performance and other factors.

Risks Relating to the Best Buy Europe Acquisition

We may not achieve the anticipated strategic objectives and financial benefits from the Best Buy Europe Acquisition.

        We anticipate that we will realize strategic and financial benefits as a result of the Best Buy Europe Acquisition, including, among others, the ability to expand into new markets and realize long-term synergies. Our ability to realize these benefits, however, is subject to risks and uncertainties, including, among others:

        Best Buy Europe's growth strategy includes expanding the retail distribution business, both in existing markets and by opening stores in new markets. Accordingly, Best Buy Europe's future growth is dependent, in part, on our ability to build, buy or lease new stores. Local land use, local zoning issues, environmental and other regulations applicable to the types of stores we desire to construct may impact Best Buy Europe's ability to find suitable locations, and also influence the cost of building, buying or leasing stores. Failure to manage effectively these and other similar factors will affect Best Buy Europe's ability to build, buy or lease new stores, which may have a material adverse effect on Best Buy Europe's future profitability.

        Best Buy Europe also will generally be subject to many of the risks set forth under Part I, Item 1A., "Risks Factors" in our Fiscal 2008 Form 10-K.

        Our failure to manage these risks, or other risks related to the Best Buy Europe Acquisition that are not presently known to us, could prevent us from realizing the expected benefits of the Best Buy Europe Acquisition and also may have a material adverse effect on our results of operations and financial condition. If our financial condition is negatively affected, our ability to make payments on the notes may be negatively affected.

A material breakdown in our relationship with The Carphone Warehouse could have a material adverse effect on Best Buy Europe's growth, business and financial condition.

        The operations of Best Buy Europe will depend, in part, upon the continued co-operation between us and The Carphone Warehouse in reaching decisions at the board of director and shareholder levels. Upon the completion of the Best Buy Europe Acquisition, we and The Carphone Warehouse entered into a shareholders' agreement, which governs our rights and those of The Carphone Warehouse with respect to our respective ownership interests in Best Buy Europe. The shareholders' agreement also sets forth our agreements with The Carphone Warehouse regarding the management and financing of Best Buy Europe, as well as certain specific matters that require the consent of both us and The Carphone Warehouse. Accordingly, in order for Best Buy Europe to proceed with those matters, we and The Carphone Warehouse will need to agree. Pursuant to the shareholders' agreement, the Best Buy designees on Best Buy Europe's board of directors have ultimate approval rights over selected senior management positions and the annual capital and operating budgets of Best Buy Europe. A

11



material breakdown in our relationship with The Carphone Warehouse could lead to an inability of the management of Best Buy Europe to make and/or implement decisions which, in turn, could have a material adverse effect on Best Buy Europe's growth, business and financial condition.

Risks Relating to the Notes and our Indebtedness

Our credit agreements contain restrictions that limit our flexibility in operating our business.

        In September 2007, we entered into a $2.5 billion five-year unsecured revolving credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, and a syndicate of banks. We entered into an amendment to this credit agreement in June 2008. We refer to this credit agreement as so amended as the "2007 Credit Agreement." On November 7, 2008, we entered into an unsecured credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, and a syndicate of banks. We refer to this agreement as the "2008 Credit Agreement" and to the 2007 Credit Agreement and the 2008 Credit Agreement, collectively, as the "Credit Agreements." The 2008 Credit Agreement terminates on December 17, 2008 and permits borrowings of up to $150 million. We are not permitted to borrow under the 2008 Credit Agreement unless all amounts available under the 2007 Credit Agreement have been borrowed and are outstanding. The Credit Agreements contain covenants and other restrictions that limit the ability of our company and our subsidiaries to engage in specified types of transactions. These covenants and other restrictions limit our company's and certain of our subsidiaries' ability to, among other things:

        The indenture governing the notes also imposes restrictions on our company and some of our subsidiaries as described under "Description of the Notes."

        There are a number of important limitations and exceptions to these covenants and restrictions. You should read "Description of the Notes" and footnote 4 to our audited consolidated financial statements included in our Fiscal 2008 Form 10-K for a description of the covenants and restrictions under the 2007 Credit Agreement.

        Under each of the Credit Agreements, we are required to maintain specified leverage and interest coverage ratios. Our ability to meet these ratios can be affected by events beyond our control, and we cannot assure you that we will meet these ratios. A breach of any such covenant could result in an event of default under the one or both of the Credit Agreements. Upon the occurrence of such an event of default, the lenders could elect to declare all amounts outstanding under the applicable Credit Agreement to be immediately due and payable and terminate all commitments to extend further credit.

We may be negatively affected by the economic crisis in the United States and key international markets.

        We must maintain liquidity to fund our working capital, service our outstanding indebtedness and finance investment opportunities, such as our recent acquisitions of Best Buy Europe and Napster. Without sufficient liquidity, we could be forced to curtail our operations or we may not be able to pursue new business opportunities. The principal sources of our liquidity are funds generated from operating activities, available cash and cash equivalents, and borrowings under the Credit Agreements and other debt financings.

12


        The capital and credit markets have been experiencing extreme volatility and disruption during the past year. These market conditions have, to a degree, affected our ability to borrow under the 2007 Credit Agreement. On September 15, 2008, Lehman Brothers Holdings Inc. ("Lehman Brothers") filed a petition under Chapter 11 of the U.S. Bankruptcy Code with the U.S. Bankruptcy Court for the Southern District of New York. A Lehman Brothers subsidiary, Lehman Commercial Paper Inc. ("Lehman CPI"), is one of the lenders under the 2007 Credit Agreement, having provided a commitment of $180 million, of which $83 million was outstanding at December 1, 2008. Since September 22, 2008, however, Lehman CPI has declined requests for funding under the 2007 Credit Agreement, and it is not certain whether Lehman CPI will participate in any future requests for funding or whether another lender might assume its commitment.

        If our current resources do not satisfy our liquidity requirements, we may have to seek additional financing. The availability of financing will depend on a variety of factors, such as economic and market conditions, the availability of credit and our credit ratings, as well as the possibility that lenders could develop a negative perception of the prospects of our company or the retail industry generally. We may not be able to successfully obtain any necessary additional financing on favorable terms, or at all.

        Economic conditions, both domestic and foreign, may affect our financial performance. Prevailing economic conditions, including unemployment levels, inflation, availability of credit, energy costs and other macro-economic factors, as well as uncertainty about future economic conditions, adversely affect consumer spending and, consequently, our business and results of operations.

We may not be able to generate sufficient cash to service all of our indebtedness, including the notes.

        Our ability to make scheduled payments on or to refinance our debt obligations depends on our financial condition and the operating performance of our subsidiaries, which are subject to prevailing economic and competitive conditions and to certain financial, business and other factors beyond our control. We cannot assure you that our subsidiaries will maintain a level of cash flows from operating activities sufficient to permit us to pay the principal of, and premium, if any, and interest on, our indebtedness, including the notes. If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay investments and capital expenditures, or to sell assets, seek additional capital or restructure or refinance our indebtedness, including the notes.

If we default on our obligations to pay indebtedness, we may not be able to make payments on the notes.

        Any default under the agreements governing our indebtedness, including a default under one or both of the Credit Agreements, that is not waived by the required lenders, could prevent us from paying the principal of, and premium, if any, and interest on, the notes and substantially decrease the market value of the notes. If our subsidiaries are unable to generate sufficient cash flows and we are otherwise unable to obtain funds necessary to meet required payments of the principal of, and premium, if any, and interest on, our indebtedness, or if we otherwise fail to comply with the various covenants, including any financial and operating covenants, in the instruments governing our indebtedness (including covenants in each of the Credit Agreements, the indenture governing the notes, and the terms of our other indebtedness), we could be in default under the terms of the agreements governing such indebtedness.

        In the event of such default, the holders of such indebtedness could elect to declare all the funds borrowed thereunder to be due and payable, together with accrued and unpaid interest, and/or the lenders under one or both of the Credit Agreements could elect to terminate their commitments thereunder, cease making further loans and we or they could be forced into bankruptcy or liquidation. If the operating performance of our subsidiaries declines, we may in the future need to obtain waivers from the required lenders under one or both of the Credit Agreements to avoid being in default. If we

13



breach the covenants under one of the Credit Agreements and seek a waiver, we may not be able to obtain a waiver from the required lenders. If this occurs, we would be in default under the instrument governing that indebtedness, the lenders could exercise the rights described above, and we could be forced into bankruptcy or liquidation.

We may not be able to repurchase the notes upon a change of control triggering event.

        Upon the occurrence of specific kinds of change of control events, we will be required to offer to repurchase the notes at 101% of their principal amount plus accrued and unpaid interest. The source of funds for any such purchase of the notes will be our available cash or cash generated from our subsidiaries' operations or other sources, including borrowings, sales of assets or sales of equity. We may not be able to repurchase the notes upon a change of control because we may not have sufficient financial resources to purchase all of the notes that are tendered upon a change of control. Our failure to repurchase the notes upon a change of control would cause a default under the indenture. Each of the Credit Agreements also provides that a change of control will be a default that permits the lenders thereunder to accelerate the maturity of borrowings thereunder. Any of our future debt agreements may contain similar provisions.

We and our subsidiaries may incur substantial indebtedness in the future.

        We and our subsidiaries are permitted under the terms of the indenture governing the notes and the Credit Agreements to incur substantial additional indebtedness in the future. Any of those additional borrowings would be structurally senior to the notes. If new indebtedness is added to our and our subsidiaries' current indebtedness levels, the related risks that we and they now face could intensify.

The notes are our unsecured obligations and do not restrict our ability to incur additional debt or prohibit us from taking other actions that could negatively affect holders of the notes.

        We are permitted under the indenture governing the notes to incur additional debt. The notes are unsecured and effectively subordinated to any secured debt that we may issue. Although we have agreed to limit our ability to issue secured debt without also securing the notes and to enter into sale and leaseback transactions, these limitations are subject to a number of exceptions. See "Description of the Notes—Covenants." The holders of any secured debt that we may issue would have priority over unsecured creditors. In the event of our bankruptcy, liquidation or similar proceeding, the holders of secured debt that we may have issued would be entitled to proceed against their collateral, and that collateral will not be available for payment of unsecured debt, including the notes.

The notes are junior to the debt obligations of our subsidiaries.

        The notes are structurally subordinated to the secured and unsecured debt, as well as other claims of creditors, of our subsidiaries.

Rating agencies may lower the ratings of the notes and our other debt securities.

        The notes received credit ratings of Baa2 from Moody's Investors Service, Inc. ("Moody's"), BBB from Standard & Poor's Ratings Services, a division of The McGraw Hill Group, Inc. ("S&P") and BBB+ from Fitch Ratings Ltd. ("Fitch"). In addition, other rating agencies may assign credit ratings to the notes in the future. An actual or potential downgrading of these ratings or the assignment of new ratings that are lower than existing ratings could adversely affect the price and liquidity of the notes or your ability to resell the notes. On June 10, 2008, S&P announced that it had reaffirmed its BBB rating on our debt securities, but that it had assigned a negative outlook to those securities. In November 2008, each of these rating agencies conducted and completed a review of our credit ratings. Moody's

14



continued to rate our debt securities as Baa2/Stable; S&P announced that it had downgraded the rating of our debt securities to BBB-, but assigned a stable outlook; and Fitch reaffirmed its rating of our debt securities as BBB+, but assigned a negative outlook. A rating is based upon information furnished by us or obtained by the relevant rating agency from its own sources and is subject to revision, suspension or withdrawal by the rating agency at any time. Rating agencies may review the ratings assigned to the notes due to developments that are beyond our control. We cannot assure you that the ratings on the notes or on our other debt securities will not be downgraded in the near future.

The book-entry form of the notes may limit the exercise of rights by beneficial owners of the notes.

        Transfers of interests in the global notes representing the notes may be effected only through book entries at DTC and its direct and indirect participants (including Clearstream Luxembourg, société anonyme and Euroclear Bank, S.A./N.V.), so that the liquidity of any secondary market in the notes may be reduced to the extent that some investors are unwilling to hold notes in book-entry form in the name of a DTC direct or indirect participant. The ability to pledge interests in the global notes may also be limited due to the lack of physical certificates. In addition, beneficial owners of interests in global notes may, in certain cases, experience delays in the receipt of payments in respect of the notes as payments will generally be forwarded by the paying agent to DTC, which will then forward payments to its direct and indirect participants for further transfer to the beneficial owners of the notes. A holder of beneficial interests in the global notes will not have a direct right under the notes to exercise rights under the notes. Instead, holders will be permitted to act only to the extent they receive appropriate proxies to do so from DTC or, if applicable, DTC's direct or indirect participants. We cannot assure holders that the procedures of DTC or DTC's nominees or direct or indirect participants will be adequate to allow them to exercise their rights under the notes in a timely manner.

USE OF PROCEEDS

        We will not receive any cash proceeds from the issuance of the exchange notes pursuant to the exchange offer. In consideration for issuing the exchange notes as contemplated in this prospectus, we will receive in exchange a like principal amount of outstanding notes, the terms of which are identical in all material respects to the exchange notes, except that the exchange notes will not contain terms with respect to transfer restrictions, registration rights or additional interest upon a failure to fulfill certain of our obligations under the registration rights agreement. The outstanding notes surrendered in exchange for the exchange notes will be retired and canceled and cannot be reissued. Accordingly, the issuance of the exchange notes will not result in any change in our capitalization.

SELECTED FINANCIAL DATA

        The following table presents our selected financial data as of the dates and periods indicated. The selected historical consolidated balance sheets and statements of earnings data as of and for the fiscal years ended March 1, 2008, March 3, 2007 and February 25, 2006 have been derived from our audited consolidated financial statements, which have been audited by Deloitte & Touche LLP, an independent registered public accounting firm. The selected historical consolidated balance sheets and statements of earnings data as of and for the fiscal years ended February 25, 2005 and February 28, 2004 have been derived from our audited consolidated financial statements, which have been audited by another independent registered public accounting firm. The selected consolidated balance sheets and statements of earnings data as of and for the six months ended August 30, 2008 and September 1, 2007 are unaudited, but include all adjustments, consisting only of normal recurring adjustments, which are, in management's opinion, necessary for a fair statement of these periods. The interim results of operations may not be indicative of the results for the full year. You should read this information in conjunction with our consolidated financial statements and related notes and "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Fiscal 2008 Form 10-K, which is incorporated by reference in this prospectus. See "Incorporation of Certain Documents by Reference."

        Certain prior-year amounts in the table below have been reclassified to conform to the fiscal 2008 presentation. In fiscal 2004, we sold our interest in The Musicland Group, Inc. ("Musicland"). All fiscal years affected by such sale reflect the classification of Musicland's financial results as discontinued operations.

We have consolidated Best Buy Europe in our financial results as part of our International segment from the date of acquisition.

In the first quarter of fiscal 2006, we early-adopted the fair value recognition provisions of Statement of Financial Accounting Standards ("SFAS") No. 123 (revised 2004), Share-Based Payment ("123(R)"), requiring us to recognize expense related to the fair value of our stock-based compensation awards. We elected the modified prospective transition method as permitted by SFAS No. 123(R) and, accordingly, financial results for years prior to fiscal 2006 have not been restated. Stock-based compensation expense in fiscal 2008, 2007 and 2006 was $105 ($72 net of tax), $121 ($82 net of tax) and $132 ($87 net of tax), respectively. Stock-based compensation expense recognized in our financial results for years prior to fiscal 2006 was not significant. Additionally, we began to recognize gift card breakage income during the third quarter of fiscal 2006. Gift card breakage income in fiscal 2008, 2007 and 2006 was $34 ($22 net of tax), $46 ($30 net of tax) and $43 ($29 net of tax), respectively.

During the fourth quarter of fiscal 2005, following a review of our lease accounting practices, we recorded a cumulative charge of $36 pre-tax ($23 net of tax) to correct our accounting for certain operating lease matters. Additionally, during the same quarter, we established a sales return liability, which reduced gross profit by $15 pre-tax ($10 net of tax). Further, in fiscal 2005, we recognized a $50 tax benefit related to the reversal of valuation allowances on deferred tax assets as a result of the favorable resolution of outstanding tax matters with the Internal Revenue Service regarding the disposition of our interest in Musicland. The tax benefit was classified as discontinued operations.

The ratio of net earnings to fixed charges is calculated by dividing earnings by fixed charges. For this purpose, "earnings" consist of income before taxes plus fixed charges and amortization of capitalized interest, less capitalized interest and "fixed charges" consist of interest expense, capitalized interest and the portion of rent expense on operating leases deemed representative of interest (estimated to be 30%).

THE EXCHANGE OFFER

General

        We are offering to exchange a like principal amount of exchange notes for any or all outstanding notes on the terms and subject to the conditions set forth in this prospectus and accompanying letter of transmittal. We refer to the offer as the "exchange offer." You may tender some or all of your outstanding notes pursuant to the exchange offer.

        As of the date of this prospectus, $500,000,000 aggregate principal amount of 6.75% Notes due 2013 is outstanding. This prospectus, together with the letter of transmittal, is first being sent to all holders of outstanding notes known to us on or about                    , 2008. Our obligation to accept outstanding notes for exchange pursuant to the exchange offer is subject to the satisfaction or waiver of certain conditions set forth under "—Conditions to the Exchange Offer" below. We anticipate that each of the conditions will be satisfied and that no waivers will be necessary.

Purpose and Effect of the Exchange Offer

        We entered into a registration rights agreement with the initial purchasers of the outstanding notes under which we agreed, under certain circumstances, to file a registration statement relating to an offer to exchange the outstanding notes for exchange notes. We also agreed to use our reasonable best efforts to cause a registration statement relating to the exchange notes to be declared effective and to cause the exchange offer to be consummated by January 31, 2009. The exchange notes have terms identical in all material respects to the terms of the corresponding outstanding notes, except that the exchange notes are registered under the Securities Act, and do not contain terms with respect to transfer restrictions, registration rights or additional interest upon a failure to fulfill certain of our obligations under the registration rights agreement. The outstanding notes were issued on June 24, 2008.

        Pursuant to the registration rights agreement and under the circumstances set forth below, we will use our reasonable best efforts to cause the SEC to declare effective a shelf registration statement with respect to the resale of the outstanding notes within the time periods specified in the registration rights agreement and to keep the shelf registration statement effective for up to two years after the effective date of the shelf registration statement. These circumstances include:

        If we fail to comply with certain obligations under the registration rights agreement, we will be required to pay additional interest to holders of the outstanding notes.

        If you wish to exchange your outstanding notes for exchange notes in the exchange offer, you will be required to make the following written representations:

        Each broker-dealer that receives exchange notes for its own account in exchange for outstanding notes, where the broker-dealer acquired the outstanding notes as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such exchange notes. See "Plan of Distribution."

Resale of Exchange Notes

        Based on interpretations by the staff of the SEC as set forth in no-action letters issued to third parties referred to below, we believe that you may resell or otherwise transfer exchange notes issued in the exchange offer without complying with the registration and prospectus delivery provisions of the Securities Act, if:

        If you are an affiliate, or are engaging in, or intend to engage in, or have any arrangement or understanding with any person to participate in, a distribution of the exchange notes, or are not acquiring the exchange notes in the ordinary course of your business, then:

        This prospectus may be used for an offer to resell, or for the resale or other transfer of, exchange notes only as specifically set forth in this prospectus. With regard to broker-dealers, only broker-dealers that acquired the outstanding notes as a result of market-making activities or other trading activities may participate in the exchange offer. Each broker-dealer that receives exchange notes for its own account in exchange for outstanding notes where such outstanding notes were acquired by such broker-dealer as a result of market-making activities or other trading activities must acknowledge that it will deliver a prospectus in connection with any resale of the exchange notes. Please read "Plan of Distribution" for more details regarding the transfer of exchange notes.

Terms of the Exchange Offer

        On the terms and subject to the conditions set forth in this prospectus and in the accompanying letter of transmittal, we will accept for exchange in the exchange offer outstanding notes that are validly tendered and not validly withdrawn prior to the expiration date. Outstanding notes may only be tendered in denominations of $2,000 and integral multiples of $1,000 in excess of $2,000. We will issue $2,000 principal amount or an integral multiple of $1,000 of exchange notes in exchange for a corresponding principal amount of outstanding notes surrendered in the exchange offer.

23


        The form and terms of the exchange notes are identical in all material respects to the form and terms of the corresponding outstanding notes, except that the exchange notes do not contain terms with respect to transfer restrictions, registration rights or additional interest upon a failure to fulfill certain of our obligations under the registration rights agreement. The exchange notes evidence the same debt as the corresponding outstanding notes. The exchange notes will be issued under and entitled to the benefits of the same indenture under which the outstanding notes were issued, and the exchange notes and the outstanding notes will constitute a single class for all purposes under the indenture. For a description of the indenture, see "Description of the Notes."

        The exchange offer is not conditioned upon any minimum aggregate principal amount of outstanding notes being tendered for exchange.

        As of the date of this prospectus, $500,000,000 aggregate principal amount of 6.75% Notes due 2013 is outstanding. This prospectus and a letter of transmittal are being sent to all registered holders of outstanding notes. There will be no fixed record date for determining registered holders of outstanding notes entitled to participate in the exchange offer.

        We intend to conduct the exchange offer in accordance with the provisions of the registration rights agreement, the applicable requirements of the Securities Act and the Exchange Act, and the rules and regulations of the SEC. Outstanding notes that are not tendered for exchange in the exchange offer will remain outstanding and continue to accrue interest and will be entitled to the rights and benefits that such outstanding notes have under the indenture, except for any rights under the registration rights agreement that by their terms terminate upon the consummation of the exchange offer.

        We will be deemed to have accepted for exchange properly tendered outstanding notes when we have given oral or written notice of the acceptance to the exchange agent. The exchange agent will act as agent for the tendering holders for the purposes of receiving the exchange notes from us and delivering exchange notes to holders. Subject to the terms of the registration rights agreement, we expressly reserve the right to amend or terminate the exchange offer and to refuse to accept outstanding notes for exchange upon the occurrence of any of the conditions specified below under "—Conditions to the Exchange Offer."

        Holders who tender outstanding notes in the exchange offer will not be required to pay brokerage commissions or fees or, subject to the instructions in the letter of transmittal, transfer taxes with respect to the exchange of outstanding notes. We will pay all charges and expenses, other than certain applicable taxes described below, in connection with the exchange offer. It is important that you read "—Fees and Expenses" below for more details regarding fees and expenses incurred in the exchange offer.

Expiration Date; Extensions, Amendments

        As used in this prospectus, the term "expiration date" means                     p.m. (New York City time) on                    , 2009, which is the        business day after the date of this prospectus. However, if we, in our sole discretion, extend the period of time for which the exchange offer is open, the term "expiration date" will mean the latest time and date to which we shall have extended the expiration of the exchange offer.

        If we extend the period of time during which the exchange offer is open, we will notify the exchange agent of any extension by oral or written notice, followed by notification to the registered holders of the outstanding notes no later than 9:00 a.m. (New York City time) on the business day after the previously scheduled expiration date.

24


        We reserve the right, in our sole discretion:

        Any delay in acceptance, extension, termination or amendment will be followed as promptly as practicable by oral or written notice to the registered holders of the outstanding notes. If we amend the exchange offer in a manner that we determine to constitute a material change, including the waiver of a material condition, we will promptly disclose the amendment by press release or other public announcement as required by Rule 14e-1(d) of the Exchange Act and will extend the offer period if necessary so that at least five business days remain in the offer following notice of the material change.

Conditions to the Exchange Offer

        Despite any other term of the exchange offer, we will not be required to accept for exchange, or to issue exchange notes in exchange for, any outstanding notes, and we may terminate or amend the exchange offer as provided in this prospectus before accepting any outstanding notes for exchange, if:

        In addition, we will not be obligated to accept for exchange the outstanding notes of any holder that has not made to us:


        We expressly reserve the right at any time or at various times to extend the period of time during which the exchange offer is open. Consequently, we may delay acceptance of any outstanding notes by notice by press release or other public announcement as required by Rule 14e-1(d) of the Exchange Act of such extension. During any such extensions, all outstanding notes previously tendered and not validly withdrawn will remain subject to the exchange offer, and we may accept them for exchange. We will return any outstanding notes that we do not accept for exchange for any reason without expense to their tendering holder promptly after the expiration or termination of the exchange offer.

        We expressly reserve the right to amend or terminate the exchange offer and to reject for exchange any outstanding notes not previously accepted for exchange upon the occurrence of any of

25



the conditions of the exchange offer specified above. We will promptly give notice by press release or other public announcement as required by Rule 14e-1(d) of the Exchange Act of any extension, amendment, non-acceptance or termination to the holders of the outstanding notes. In the case of any extension, such notice will be issued no later than 9:00 a.m. (New York City time) on the business day after the previously scheduled expiration date.

        These conditions are for our sole benefit, and we may assert them regardless of the circumstances that may give rise to them so long as such circumstances do not arise due to our action or inaction or waive them in whole or in part at any or at various times in our sole discretion. If we fail at any time to exercise any of these rights, it will not constitute a waiver of such right. Each such right will be deemed an ongoing right that we may assert at any time or at various times.

Procedures for Tendering Outstanding Notes

        Only a holder of outstanding notes may tender their outstanding notes in the exchange offer. To tender outstanding notes in the exchange offer, you must comply with either of the following requirements:

        In addition, you must comply with one of the following requirements:

        To be tendered effectively, the exchange agent must receive any physical delivery of the letter of transmittal and other required documents at the address set forth below under "—Exchange Agent" prior to the expiration date.

        Your tender of outstanding notes that is not validly withdrawn prior to the expiration date constitutes an agreement between us and you upon the terms and subject to the conditions described in this prospectus and in the letter of transmittal.

        The method of delivery of outstanding notes, letter of transmittal and all other required documents to the exchange agent is at your election and risk. Rather than mail these items, we recommend that you use an overnight or hand delivery service. In all cases, you should allow sufficient time to assure timely delivery to the exchange agent before the expiration date. You should not send letters of transmittal or certificates representing outstanding notes to us. You may request that your broker, dealer, commercial bank, trust company or other nominee effect the above transactions for you.

        If you are a beneficial owner whose outstanding notes are held in the name of a broker, dealer, commercial bank, trust company, or other nominee and you wish to tender your outstanding notes, you should promptly instruct the registered holder to tender outstanding notes on your behalf.

        You must make these arrangements or follow these procedures before completing and executing the letter of transmittal and delivering the outstanding notes.

26


        Signatures on the letter of transmittal or a notice of withdrawal, as the case may be, must be guaranteed by a member firm of the Security Transfer Agent Medallion Signature Program or by any other "eligible guarantor institution" within the meaning of Rule 17A(d)-15 under the Exchange Act (an "Eligible Guarantor Institution") unless the outstanding notes surrendered for exchange are tendered:

        If the applicable letter of transmittal is signed by a person other than the registered holder of any outstanding notes listed on the outstanding notes, such outstanding notes must be endorsed or accompanied by a properly completed bond power. The bond power must be signed by the registered holder as the registered holder's name appears on the outstanding notes and an Eligible Guarantor Institution must guarantee the signature on the bond power.

        If the applicable letter of transmittal or any certificates representing outstanding notes or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations, or others acting in a fiduciary or representative capacity, those persons should so indicate when signing and, unless waived by us, they should also submit evidence satisfactory to us of their authority to so act.

        The exchange agent and DTC have confirmed that any financial institution that is a participant in DTC's system may use DTC's Automated Tender Offer Program to tender. Participants in the program may, instead of physically completing and signing the letter of transmittal and delivering it to the exchange agent, electronically transmit their acceptance of the exchange by causing DTC to transfer the outstanding notes to the exchange agent in accordance with DTC's Automated Tender Offer Program procedures for transfer. DTC will then send an agent's message to the exchange agent. The term "agent's message" means a message transmitted by DTC, received by the exchange agent and forming part of the book-entry confirmation, that states that:

Acceptance of Exchange Notes

        In all cases, we will promptly issue exchange notes for outstanding notes that we have accepted for exchange under the exchange offer only after the exchange agent timely receives:

        By tendering outstanding notes pursuant to the exchange offer, you will represent to us that, among other things:

27


        In addition, each broker-dealer that is to receive exchange notes for its own account in exchange for outstanding notes must represent that such outstanding notes were acquired by that broker-dealer as a result of market-making activities or other trading activities and must acknowledge that it will deliver a prospectus that meets the requirements of the Securities Act in connection with any resale of the exchange notes. The applicable letter of transmittal states that by so acknowledging 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. See "Plan of Distribution."

        Our interpretation of the terms and conditions of the exchange offer, including the letters of transmittal and the instructions to the letters of transmittal, and our resolution of all questions as to the validity, form, eligibility, including time of receipt, and acceptance of outstanding notes tendered for exchange, will be final and binding on all parties. We reserve the absolute right to reject any and all tenders of any particular outstanding notes not properly tendered and to not accept any particular outstanding notes if the acceptance might, in our or our counsel's judgment, be unlawful. We also reserve the absolute right to waive any defects or irregularities as to any particular outstanding notes prior to the expiration date.

        Unless waived, any defects or irregularities in connection with tenders of outstanding notes for exchange must be cured within such reasonable period of time as we determine. Neither we, the exchange agent, nor any other person will be under any duty to give notification of any defect or irregularity with respect to any tender of outstanding notes for exchange, nor will we or any of them incur any liability for any failure to give notification. Any outstanding notes received by the exchange agent that are not properly tendered and as to which the irregularities have not been cured or waived will be returned by the exchange agent to the tendering holder, unless otherwise provided in the applicable letter of transmittal, promptly after the expiration date.

Book-Entry Delivery Procedures

        Promptly after the date of this prospectus, the exchange agent will establish an account with respect to the outstanding notes at DTC as the book-entry transfer facility, for purposes of the exchange offer. Any financial institution that is a participant in DTC's system may make book-entry delivery of the outstanding notes by causing DTC to transfer those outstanding notes into the exchange agent's account at the facility in accordance with the facility's procedures for such transfer. To be timely, book-entry delivery of outstanding notes requires receipt of a confirmation of a book-entry transfer, a "book-entry confirmation," prior to the expiration date. In addition, although delivery of outstanding notes may be effected through book-entry transfer into the exchange agent's account at DTC, the applicable letter of transmittal or a manually signed facsimile thereof, together with any required signature guarantees and any other required documents, or an "agent's message," as defined under "—Procedures for Tendering Outstanding Notes," in connection with a book-entry transfer, must, in any case, be delivered or transmitted to and received by the exchange agent at its address set forth below under "—Exchange Agent" prior to the expiration date to receive exchange notes for tendered outstanding notes, or the guaranteed delivery procedure described below must be complied with. Tender will not be deemed made until such documents are received by the exchange agent. Delivery of documents to DTC does not constitute delivery to the exchange agent.

Guaranteed Delivery Procedures

        If you wish to tender outstanding notes that are not immediately available or you cannot deliver your outstanding notes, the letter of transmittal or any other required documents to the exchange agent

28



or comply with the applicable procedures under DTC's Automatic Tender Offer Program prior to the expiration date, you may still tender if:

        Upon request, the exchange agent will send to you a notice of guaranteed delivery if you wish to tender your notes according to the guaranteed delivery procedures.

Withdrawal Rights

        Except as otherwise provided in this prospectus, you may withdraw your tender of outstanding notes at any time prior to                      p.m. (New York City time) on the expiration date.

        For a withdrawal to be effective:

        Any notice of withdrawal must:


        If certificates for outstanding notes have been delivered or otherwise identified to the exchange agent, then, prior to the release of such certificates, you must also submit:

        If outstanding notes have been tendered pursuant to the procedures for book-entry transfer described above, any notice of withdrawal must specify the name and number of the account at DTC to be credited with the withdrawn outstanding notes and otherwise comply with the procedures of the

29



facility. We will determine all questions as to the validity, form, and eligibility, including time of receipt of notices of withdrawal and our determination will be final and binding on all parties. Any outstanding notes so withdrawn will be deemed not to have been validly tendered for exchange for purposes of the exchange offer. Any outstanding notes that have been tendered for exchange but that are not exchanged for any reason will be returned to their holder, without cost to the holder, or, in the case of book-entry transfer, the outstanding notes will be credited to an account at DTC, promptly after withdrawal, rejection of tender or termination of the exchange offer. Properly withdrawn outstanding notes may be retendered by following the procedures described under "—Procedures for Tendering Outstanding Notes" above at any time on or prior to the expiration date.

Fees and Expenses

        The registration rights agreement provides that we will bear all expenses in connection with the performance of our obligations relating to the registration of the exchange notes and the conduct of the exchange offer. These expenses include registration and filing fees, accounting and legal fees and printing costs, among others. We will pay the exchange agent reasonable and customary fees for its services and reasonable out-of-pocket expenses. We will also reimburse brokerage houses and other custodians, nominees and fiduciaries for customary mailing and handling expenses incurred by them in forwarding this prospectus and related documents to their clients that are holders of outstanding notes and for handling or tendering for such clients.

        We have not retained any dealer-manager in connection with the exchange offer and will not pay any fee or commission to any broker, dealer, nominee or other person, other than the exchange agent, for soliciting tenders of outstanding notes pursuant to the exchange offer.

30


Accounting Treatment

        We will record the exchange notes in our accounting records at the same carrying value as the outstanding notes, which is the aggregate principal amount as reflected in our accounting records on the date of exchange. Accordingly, we will not recognize any gain or loss for accounting purposes upon the consummation of the exchange offer.

Transfer Taxes

        We will pay all transfer taxes, if any, applicable to the exchange of outstanding notes in the exchange offer. The tendering holder, however, will be required to pay any transfer taxes, whether imposed on the registered holder or any other person, if:

        If satisfactory evidence of payment of such taxes is not submitted with the letter of transmittal, the amount of such transfer taxes will be billed to that tendering holder.

        Holders who tender their outstanding notes for exchange will not be required to pay any transfer taxes. However, holders who instruct us to register exchange notes in the name of, or request that outstanding notes not tendered or not accepted in the exchange offer be returned to, a person other than the registered tendering holder will be required to pay any applicable transfer tax.

Consequences of Failure to Exchange

        If you do not exchange your outstanding notes for exchange notes in the exchange offer, your outstanding notes will remain subject to the restrictions on transfer as set forth in the legend printed on the outstanding notes as a consequence of the issuance of the outstanding notes pursuant to the exemptions from, or in transactions not subject to, the registration requirements of the Securities Act and applicable state securities laws.

        In general, you may not offer or sell your outstanding notes unless they are registered under the Securities Act or if the offer or sale is exempt from registration under the Securities Act and applicable state securities laws. Except as required by the registration rights agreement, we do not intend to register resales of the outstanding notes under the Securities Act.

Other

        Participating 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 decision on what action to take.

        We may in the future seek to acquire untendered outstanding notes in open market or privately negotiated transactions, through a subsequent exchange offer or otherwise. We have no present plans to acquire any outstanding notes that are not tendered in the exchange offer or to file a registration statement to permit resales of any untendered outstanding notes.

31



DESCRIPTION OF THE NOTES

General

        The outstanding notes were issued, and the exchange notes will be issued, under the indenture between us and Wells Fargo Bank, N.A., as trustee. We refer to the outstanding notes and the exchange notes, collectively, as the "notes." The terms of the notes include those stated in the indenture and those made part of the indenture by reference to the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). Holders of notes are referred to the indenture and the Trust Indenture Act for all of the terms of the notes.

        The following description of the notes summarizes the material provisions of the indenture. It is not complete and is qualified in its entirety by reference to the indenture, including the definitions therein of certain terms used below. We urge you to read the indenture because that agreement, and not this description, defines your rights as a holder of the notes. A copy of the indenture is attached as an exhibit to our Current Report on Form 8-K filed on June 24, 2008.

        The definitions of certain terms used in the following summary are set forth below under "—Certain Definitions." For purposes of this summary, references to "the Company," "we," "our" and "us" and other similar references are to Best Buy Co., Inc. and not to any of our subsidiaries.

Principal, Maturity and Interest

        The outstanding notes were initially issued in the aggregate principal amount of $500,000,000. Unless earlier redeemed or purchased, the notes will mature on July 15, 2013.

        The notes bear interest at a rate of 6.75% per annum, subject to adjustments as described under "—Interest Rate Adjustment" below, from the original issuance date of the outstanding notes or from the most recent interest payment date for which interest on the notes has been paid or provided for. Interest is payable semi-annually in arrears on January 15 and July 15 each year, commencing on January 15, 2009 (each, an "interest payment date") to the person in whose name any such note is registered at the close of business on the January 1 or July 1 (whether or not a business day) prior to such interest payment date (each, a "record date"), notwithstanding any transfer or exchange of such notes subsequent to the record date and prior to such interest payment date, except that, if and to the extent we default in the payment of the interest due on such interest payment date and the applicable grace period shall have expired, such defaulted interest may at our option be paid to the persons in whose names notes are registered at the close of business on a subsequent record date (which will not be less than 10 days prior to the date of payment of such defaulted interest) established by notice given by mail by or on our behalf to the registered holders of the notes not less than 15 days preceding such subsequent record date.

        Interest is computed on the basis of a 360-day year consisting of twelve 30-day months and, in the case of an incomplete month, the number of days elapsed.

        If the date on which any interest payment or principal payment is to be made is not a business day in the place of payment of such interest or principal, such payment will be made on the next day which is a business day in the place of payment of such interest or principal without any further interest or other amounts being paid or payable in connection therewith. A "business day" means any day, other than Saturday or Sunday, that is neither a legal holiday nor a day on which banking institutions are authorized or required by law or regulation to close in New York City.

        The notes are not entitled to the benefit of any sinking fund.

32


Interest Rate Adjustment

        The interest rate payable on the notes is subject to adjustments from time to time if either of Moody's or S&P or, in either case, any Substitute Rating Agency thereof, downgrades (or subsequently upgrades) the rating assigned to the notes in the manner described below.

        If the rating of the notes from Moody's or any Substitute Rating Agency thereof is decreased to a rating set forth in the immediately following table, the interest rate on the notes will increase from the interest rate payable on the notes on the date of their initial issuance by the percentage points set forth below opposite that rating.

Moody's
Rating*
  Percentage
Points
 

Ba1

    0.25  

Ba2

    0.50  

Ba3

    0.75  

B1 or below

    1.00  

*
Including the equivalent ratings of any Substitute Rating Agency.

        If the rating of the notes from S&P or any Substitute Rating Agency thereof is decreased to a rating set forth in the immediately following table, the interest rate on the notes will increase from the interest rate payable on the notes on the date of their initial issuance by the percentage points set forth below opposite that rating.

    0.25  

BB

    0.50  

BB-

    0.75  

B+ or below

    1.00  

*
Including the equivalent ratings of any Substitute Rating Agency.

        If at any time the interest rate on the notes has been adjusted upward and either Moody's or S&P (or, in either case, a Substitute Rating Agency thereof), as the case may be, subsequently increases its rating of the notes to any of the ratings set forth in the tables above, the interest rate on the notes will be decreased such that the interest rate for the notes equals the interest rate payable on the notes on the date of the initial issuance of the outstanding notes plus the applicable percentage points set forth opposite the ratings in the tables above in effect immediately following the increase. If Moody's or any Substitute Rating Agency thereof subsequently increases its rating of the notes to Baa3 (or its equivalent, in the case of a Substitute Rating Agency) or higher and S&P or any Substitute Rating Agency thereof increases its rating to BBB- (or its equivalent, in the case of a Substitute Rating Agency) or higher, the interest rate on the notes will be decreased to 6.75% per annum (which was the interest rate payable on the outstanding notes on their initial issuance date).

        Each adjustment required by any decrease or increase in a rating set forth above, whether occasioned by the action of Moody's or S&P (or, in either case, any Substitute Rating Agency thereof), will be made independent of any and all other adjustments. For example, if the notes are rated Ba1 by Moody's and BB+ by S&P, the interest rate on the notes would increase to a rate of 6.75% per annum plus 0.50 percentage points. In no event shall (1) the interest rate on the notes be reduced to below a rate of 6.75% per annum or (2) the total increase in the interest rate on the notes exceed 2.00 percentage points above 6.75% per annum.

33


        No adjustments in the interest rate of the notes will be made solely as a result of a Rating Agency ceasing to provide a rating of the notes. If at any time less than two Rating Agencies provide a rating of the notes for reason beyond our control, we will use our commercially reasonable efforts to obtain a rating of the notes from a Substitute Rating Agency, to the extent one exists, and if a Substitute Rating Agency exists, for purposes of determining any increase or decrease in the interest rate on the notes pursuant to the table above (a) such Substitute Rating Agency will be substituted for the last Rating Agency to provide a rating of the notes but which has since ceased to provide such rating, (b) the relative ratings scale used by such Substitute Rating Agency to assign ratings to senior unsecured debt will be determined in good faith by an independent investment banking institution of national standing appointed by us and, for purposes of determining the applicable ratings included in the applicable table above with respect to such Substitute Rating Agency, such ratings will be deemed to be the equivalent ratings used by Moody's or S&P, as applicable, in such table and (c) the interest rate on the notes will increase or decrease, as the case may be, such that the interest rate equals 6.75% per annum plus the appropriate percentage points, if any, set forth opposite the rating from such Substitute Rating Agency in the applicable table above (taking into account the provisions of clause (b) above) (plus any applicable percentage points resulting from a decreased rating by the other Rating Agency).

        For so long as only one Rating Agency provides a rating of the notes, any subsequent increase or decrease in the interest rate of the notes necessitated by a reduction or increase in the rating by such Rating Agency shall be twice the percentage points set forth in the applicable table above. For so long as no Rating Agency provides a rating of the notes, the interest rate on the notes will increase to, or remain at, as the case may be, 2.00 percentage points above 6.75% per annum.

        In addition, the interest rate on the notes will permanently cease to be subject to any adjustment described above (notwithstanding any subsequent decrease in the ratings by either or both Rating Agencies) if the notes become rated A2 and A (or its equivalent, in the case of a Substitute Rating Agency) or higher by Moody's and S&P, respectively (or, in either case, any Substitute Rating Agency thereof), or one of these ratings if the notes are only rated by one Rating Agency.

        Any interest rate increase or decrease described above will take effect from the first day of the interest period during which a rating change requires an adjustment in the interest rate. If Moody's or S&P or any Substitute Rating Agency thereof changes its rating of the notes more than once during any particular interest period, the last change by such agency during such period will control for purposes of any interest rate increase or decrease relating to such Rating Agency's action.

Form and Denominations

        The exchange notes will be issued only in fully registered form, without coupons, in denominations of $2,000 and any integral multiple of $1,000 in excess thereof.

        The exchange notes will be issued in book-entry form and will be represented by global certificates deposited with, or on behalf of, DTC and registered in the name of Cede & Co., DTC's nominee. Beneficial interests in the exchange notes will be shown on, and transfers will be effected only through, records maintained by DTC or its nominee; and these interests may not be exchanged for certificated notes, except in limited circumstances. See "—Global Notes; Book Entry System."

Listing

        The notes are not listed on any securities exchange or market and we do not intend to list the notes on any securities exchange or market.

34


Ranking

        The notes are our senior unsecured obligations and rank equally with all of our other existing and future senior unsecured obligations.

        The notes are effectively subordinated to any secured obligations of our company to the extent of the value of the assets securing such obligations. The indenture limits the amount of secured indebtedness that we or our North American Subsidiaries may incur pursuant to the covenant described under "—Covenants—Limitation on Liens." This covenant is subject to important exceptions described below.

        We conduct many of our operations through our Subsidiaries, which generate a substantial portion of our operating income and cash. As a result, distributions or advances from our Subsidiaries are a major source of funds necessary to meet our debt service and other obligations. Contractual provisions, laws or regulations, as well as any Subsidiary's financial condition and operating requirements, may limit our ability to obtain cash required to service our debt obligations, including making payments on the notes.

        The notes are structurally subordinated to all existing and future obligations of our Subsidiaries, including claims with respect to trade payables. The indenture limits the amount of Indebtedness that our North American Subsidiaries may incur pursuant to the covenant described under "—Covenants—Limitation on Incurrence of Indebtedness by North American Subsidiaries." This covenant is subject to important exceptions described below.

Further Issuances

        We may, from time to time, without notice to or consent of the holders of the notes, increase the principal amount of the notes that may be issued under the indenture and issue such increased principal amount (or any portion thereof), in which case any additional notes so issued will have the same form and terms (other than the date of issuance and, under certain circumstances, the date from which interest thereon will begin to accrue), and will carry the same right to receive accrued and unpaid interest, as the notes previously issued, and such additional notes will form a single series with the notes, including for purposes of voting, redemptions and offers to purchase.

Optional Redemption

        At any time and from time to time, the notes are redeemable, as a whole or in part, at our option, on at least 30 days, but not more than 60 days, prior notice mailed to the registered address of each holder, at a redemption price equal to the greater of:

plus, in either case, accrued and unpaid interest to, but not including, the date of redemption.

        "Comparable Treasury Issue" means the United States Treasury security or securities selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the notes 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 notes of a comparable maturity to the remaining term of such notes.

35


        "Comparable Treasury Price" means, with respect to any redemption date (A) the arithmetic average of four Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (B) if the Company obtains fewer than four such Reference Treasury Dealer Quotations, the arithmetic average of all such quotations for such redemption date.

        "Independent Investment Banker" means one of the Reference Treasury Dealers appointed by the Company after consultation with the Trustee; provided, however, that if such Reference Treasury Dealer ceases to be a Primary Treasury Dealer, we will substitute another Primary Treasury Dealer.

        "Reference Treasury Dealer" means either of J.P. Morgan Securities Inc. and Goldman, Sachs & Co. and their affiliates which are primary U.S. Government securities dealers in New York City, and their respective successors plus two other primary U.S. Government securities dealers in New York City selected by us; provided, however, that if any of the foregoing or their affiliates shall cease to be a primary U.S. Government securities dealer in New York City (a "Primary Treasury Dealer"), we will substitute therefor another Primary Treasury Dealer.

        "Reference Treasury Dealer Quotations" means, with respect to each Reference Treasury Dealer and any redemption date, the arithmetic average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such Reference Treasury Dealer at 3:30 p.m. (New York City time) on the third business day preceding such redemption date.

        "Treasury Rate" means, with respect to any redemption date, the rate per annum equal to the semiannual equivalent yield to maturity or interpolated (on a day count basis) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.

        On and after the redemption date for the notes, interest will cease to accrue on the notes or any portion thereof called for redemption, unless we default in the payment of the redemption price. On or before the redemption date for the notes, we will deposit with a paying agent, or the Trustee, funds sufficient to pay the redemption price of, and accrued and unpaid interest on, such notes to be redeemed on that redemption date. If less than all of the notes are to be redeemed, the notes to be redeemed will be selected by the Trustee by such method as the Trustee deems fair and appropriate; provided, however, that no notes of a principal amount of $2,000 or less shall be redeemed in part.

        Notice of any redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each holder of the notes to be redeemed. Once notice of redemption is mailed, the notes called for redemption will become due and payable on the redemption date and at the applicable redemption price, plus accrued and unpaid interest to the redemption date.

Covenants

        The indenture includes the covenants discussed below. Except as set forth below, the indenture does not restrict us from incurring Indebtedness or other obligations, paying dividends or making distributions of our capital stock or purchasing or redeeming our capital stock. The indenture also does not require the maintenance of any financial ratios or specified levels of net worth or liquidity.

Limitation on Liens

        The indenture provides that the Company will not, and will not permit any of its North American Subsidiaries, directly or indirectly, to issue, assume or guarantee any Indebtedness if that Indebtedness is secured by any Lien upon any Principal Property of the Company or of a North American

36



Subsidiary, without effectively securing the notes equally and ratably with that Indebtedness for so long as such Indebtedness is so secured. The foregoing restriction does not apply to:

        The foregoing limitation on liens shall not apply to the issuance, assumption or guarantee by the Company or any North American Subsidiary of Indebtedness secured by a Lien which would otherwise be subject to the foregoing restrictions up to an aggregate amount which, together with all other Indebtedness of the Company and our North American Subsidiaries secured by Liens (not including Liens permitted under the foregoing exceptions) that would otherwise be subject to the foregoing restrictions and the Value of Sale and Leaseback Transactions existing at that time (other than Sale and Leaseback Transactions that, if such Sale and Leaseback Transaction had been a Lien, would have been permitted under clause (1) above and other than Sale and Leaseback Transactions as to which application of amounts have been made in accordance with clause (3) under "—Limitation on Sale and Leaseback Transactions"), does not at the time exceed the greater of 15% of Consolidated Net Tangible Assets and 10% of Consolidated Capitalization.

        The indenture does not limit the ability of the Company's Subsidiaries that are not North American Subsidiaries to issue, assume or guarantee any secured Indebtedness.

Limitation on Sale and Leaseback Transactions

        The indenture provides that the Company will not, and will not permit any of its North American Subsidiaries to, enter into any Sale and Leaseback Transaction unless the net proceeds of the Sale and

37



Leaseback Transaction are at least equal to the sum of all costs incurred by the Company or any North American Subsidiary in connection with the acquisition of, and construction of any improvements on, the Principal Property to be leased and:

        The indenture does not limit the ability of the Company's Subsidiaries that are not North American Subsidiaries to enter into Sale and Leaseback Transactions.

Limitation on Incurrence of Indebtedness by North American Subsidiaries

        The indenture provides that the Company will not permit any North American Subsidiary to incur, create or assume any Indebtedness, except:

38


        The indenture does not limit the ability of the Company's Subsidiaries that are not North American Subsidiaries to incur Indebtedness.

Merger, Consolidation or Sale or Conveyance of Assets

        The indenture provides that we may not consolidate or merge with or into any other Person or convey or transfer our properties and assets substantially as an entirety to any Person, unless:

        In the case of any consolidation, merger, conveyance or transfer, the successor Person will succeed to and be substituted for the Company as obligor on the notes, with the same effect as if it had been named in the indenture as the Company, and we will be relieved of all obligations under the notes and the indenture.

        The covenant described above includes a phrase relating to the sale, assignment, conveyance, transfer or other disposition of "assets substantially as an entirety." Like the phrase "all or substantially all" of a company's assets, there is no precise, established definition of the phrase "assets substantially as an entirety" under applicable law. In interpreting this phrase, courts may, among other things, make a subjective determination as to the portion of assets conveyed, considering many factors, including the value of assets conveyed, the proportion of a company's income derived from the assets conveyed and

39



the significance of those assets to the ongoing business of the company. To the extent the meaning of such phrase is uncertain, uncertainty will exist as to whether or not the covenant described above may apply.

Offer to Purchase upon Change of Control Triggering Event

        If a Change of Control Triggering Event occurs with respect to the notes, unless we have exercised our option to redeem the notes as described above, we will be required to make an offer (the "Change of Control Offer") to each holder to repurchase all or any part (equal to $2,000 or any integral multiple of $1,000 in excess thereof) of that holder's notes on the terms set forth in the notes. In the Change of Control Offer, we will be required to offer payment in cash equal to 101% of the aggregate principal amount of notes repurchased, plus accrued and unpaid interest, if any, on the notes repurchased up to, but not including, the date of repurchase (the "Change of Control Payment"). Within 30 days following any Change of Control Triggering Event or, at our option, prior to any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, a notice will be mailed to holders of the notes describing the transaction that constitutes or may constitute the Change of Control Triggering Event with respect to the notes and offering to repurchase the notes on the date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed or, if the notice is mailed prior to the Change of Control, no earlier than 30 days and no later than 60 days from the date on which the Change of Control Triggering Event with respect to the notes occurs (the "Change of Control Payment Date"). The notice will, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date.

        On the Change of Control Payment Date, we will, to the extent lawful:

        We will publicly announce the results of the Change of Control Offer on or as soon as possible after the date of purchase.

        Except as described above, the indenture does not contain provisions that permit holders to require us to purchase or redeem the notes in the event of a takeover, recapitalization or similar transaction.

        We will not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the time and otherwise in compliance with the requirements for an offer made by us and the third party purchases all notes properly tendered and not withdrawn under its offer. In addition, we will not repurchase any notes if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the indenture, other than a default in the payment of the Change of Control Payment upon a Change of Control Triggering Event.

        We will comply in all material respects with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the notes as a result of a Change of Control

40



Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the notes, we will comply with those securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control Offer provisions of the notes by virtue of any such conflict.

Events of Default

        Each of the following constitutes an "Event of Default" under the indenture with respect to the notes:

        If an Event of Default (other than an Event of Default described in clause (5) above) shall occur and be continuing, either the Trustee or the holders of at least 25% in aggregate principal amount of the outstanding notes by written notice as provided in the indenture may declare the principal amount of (together with accrued interest on) all the notes to be due and payable immediately. If an Event of Default described in clause (5) above shall occur, the principal amount of (together with accrued interest on) all the notes will automatically, and without any action by the Trustee or any holder, become immediately due and payable. After any such acceleration, but before a judgment or decree based on acceleration, the holders of a majority in aggregate principal amount of the outstanding notes may, under certain circumstances, rescind and annul such acceleration if all events of default, other than the non-payment of accelerated principal, have been cured or waived as provided in the indenture. For information as to waiver of defaults, see "—Modification and Waiver."

41


        Subject to the provisions of the indenture relating to the duties of the Trustee in case an Event of Default shall occur and be continuing, the Trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request or direction of any of the holders, unless the Trustee has been offered indemnity reasonably satisfactory to it. Subject to such provisions for the indemnification of the Trustee, the holders of a majority in aggregate principal amount of the outstanding notes will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee.

        No holder of a note will have any right to institute any proceeding with respect to the indenture, or for the appointment of a receiver or a trustee, or for any other remedy thereunder, unless:


        However, these limitations do not apply to a suit instituted by a holder of a note for the enforcement of payment of the principal of or any premium or interest on such note on or after the applicable due date specified in such note (after giving effect to any applicable grace period specified in the indenture).

        Pursuant to the Trust Indenture Act, we will furnish to the Trustee, at least annually, a certificate from our principal financial officer or principal accounting officer as to our compliance with the terms of the indenture and, upon our becoming aware of any Event of Default, a statement specifying such Event of Default and what action we are taking or propose to take with respect thereto.

        "Rating Event" means, with respect to notes, the rating on such notes is lowered independently by each of the Rating Agencies and the notes are rated below an Investment Grade Rating by each of the Rating Agencies on any day during the period commencing on the earlier of the date of the first public notice of the occurrence of a Change of Control or our intention to effect a Change of Control and ending 60 days following consummation of such Change of Control (which period will be extended so

Notices

        Notices regarding the notes will be sent solely to registered holders, using their addresses as listed in the list of registered holders of the notes.

Defeasance and Covenant Defeasance

        We may elect, at our option at any time, to have the provisions of the indenture relating to defeasance and discharge of indebtedness, or relating to defeasance of certain restrictive covenants, applied to the notes.

Defeasance and Discharge

        The indenture provides that, upon our exercise of our option to have the provisions relating to defeasance and discharge applied to the outstanding notes, we will be discharged from all our obligations with respect to such notes (except for certain obligations to exchange or register the transfer of notes, to replace stolen, lost, destroyed or mutilated notes, to maintain paying agencies and to hold

45



monies for payment in trust) upon the deposit in trust for the benefit of the holders of such notes of money or U.S. government obligations, or both, which, through the payment of principal and interest in respect thereof in accordance with their terms, will provide money in an amount sufficient to pay the principal of and interest on such notes on their stated maturity in accordance with the terms of the indenture and the notes. Such defeasance and discharge may occur only if, among other things, we have delivered to the Trustee an opinion of counsel to the effect that we have received from, or there has been published by, the U.S. Internal Revenue Service a ruling, or there has been a change in tax law, in either case to the effect that holders of such notes will not recognize gain or loss for federal income tax purposes as a result of such deposit, defeasance and discharge and will be subject to federal income tax on the same amount, in the same manner and at the same times as would have been the case if such deposit, defeasance and discharge were not to occur.

Defeasance of Certain Covenants

        The indenture provides that, upon our exercise of our option to have provisions relating to defeasance of certain covenants applied to the outstanding notes, we may omit to comply with some restrictive covenants, including those described above under "—Covenants," and such omission will be deemed not to be an Event of Default with respect to the notes. We, in order to exercise such option, will be required to deposit, in trust for the benefit of the holders of such notes, money or U.S. government obligations, or both, which, through the payment of principal and interest in respect thereof in accordance with their terms, will provide money in an amount sufficient to pay the principal of and interest on such notes on their stated maturity in accordance with the terms of the indenture and the notes. We will also be required, among other things, to deliver to the Trustee an opinion of counsel to the effect that holders of such notes will not recognize gain or loss for federal income tax purposes as a result of such deposit and defeasance and will be subject to federal income tax on the same amount, in the same manner and at the same times as would have been the case if such deposit and defeasance were not to occur. In the event we exercise this option with respect to the outstanding notes and such notes are declared due and payable because of the occurrence of any Event of Default, the amount of money and U.S. government obligations so deposited in trust would be sufficient to pay amounts due on such notes at their stated maturity but may not be sufficient to pay amounts due on such notes upon any acceleration resulting from such Event of Default. In such case, we would remain liable for such payments.

Satisfaction and Discharge

        The indenture will cease to be of further effect, and we will be deemed to have satisfied and discharged the indenture with respect to the notes, when the following conditions have been satisfied:

        We will remain obligated to provide for registration of transfer and exchange and to provide notices of redemption.

46


Modification and Waiver

        We may make modifications and amendments to the indenture with the consent of the holders of a majority in aggregate outstanding principal amount of the notes; provided, however, that no such modification or amendment may, without the consent of the holder of each note affected thereby:

        The holders of a majority in aggregate outstanding principal amount of the notes may waive our compliance with certain restrictive provisions of the indenture. The holders of a majority in aggregate outstanding principal amount of the notes may waive any past default under the indenture, except a default in the payment of principal, premium or interest that has not been cured.

        We may amend or supplement the indenture without notice to or the consent of any holder, in order, among other things, to:

47


SEC Reports

        We are required to file with the Trustee, within 15 days after we are required to file the same with the SEC, copies of the annual reports and of the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may prescribe) that we may be required to file with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act. If we are not required to file information, documents or reports pursuant to either of those sections, then we are required to file with the Trustee and the SEC such reports, if any, as may be prescribed by the SEC at such time.

The Trustee

        Wells Fargo Bank, N.A. is the Trustee under the indenture and also is the initial paying agent, registrar and transfer agent for the notes.

        The indenture provides that, except during the continuance of an Event of Default under the indenture, the Trustee will perform only such duties as are specifically set forth in the indenture. Under the indenture, the holders of a majority in outstanding principal amount of the notes will have the right to direct the time, method and place of conducting any proceeding or exercising any remedy available to the Trustee, subject to certain exceptions. If an Event of Default has occurred and is continuing, the Trustee will exercise such rights and powers vested in it under the indenture and is obligated to use the same degree of care and skill in its exercise as a prudent person would exercise under the circumstances in the conduct of such person's own affairs.

        The indenture contains limitations on the rights of the Trustee, should it become a creditor of the Company or any of our subsidiaries, to obtain payment of claims in certain cases or to realize on certain property received by it in respect of any such claims, as security or otherwise. The Trustee is permitted to engage in other transactions. However, if the Trustee acquires any prohibited conflicting interest, it must eliminate the conflict or resign.

        The Trustee may resign or be removed and a successor trustee may be appointed.

Governing Law

        The indenture and the notes are governed by, and construed in accordance with, the laws of the State of New York.

Global Notes; Book-Entry System

Global Notes

        The exchange notes will be represented by global certificates in fully registered, book-entry form without interest coupons, will be deposited with the Trustee as custodian for DTC, and will be registered in the name of Cede & Co. or another nominee designated by DTC except in limited circumstances.

Certain Book-Entry Procedures for the Global Notes

        All interests in the global notes will be subject to the operations and procedures of DTC, Euroclear Bank, S.A./N.V. ("Euroclear") and Clearstream Luxembourg, société anonyme ("Clearstream Luxembourg"). The descriptions of the operations and procedures of DTC, Euroclear and Clearstream Luxembourg set forth below are 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 change by them from time to time. Investors are urged to contact the relevant system or its participants directly for additional information regarding their respective procedures.

48


         DTC.    DTC has advised us that it is:

        DTC was created to hold securities for its participants (collectively, the "participants") and to facilitate the clearance and settlement of securities transactions between its participants through electronic book-entry changes to the accounts of its participants, thereby eliminating the need for physical transfer and delivery of certificates. DTC's participants include securities brokers and dealers (including some or all of the initial purchasers), banks and trust companies, clearing corporations and certain other organizations. Indirect access to DTC's system is also available to other entities such as Clearstream Luxembourg, Euroclear, banks, brokers, dealers and trust companies (collectively, the "indirect participants") that clear through or maintain a custodial relationship with a participant, either directly or indirectly. Investors who are not participants may beneficially own securities held by or on behalf of DTC only through participants or indirect participants in DTC.

         Clearstream Luxembourg.    Clearstream Luxembourg is incorporated under the laws of Luxembourg as a professional depositary. Clearstream Luxembourg holds securities for its participating organizations ("Clearstream Luxembourg Participants") and facilitates the clearance and settlement of securities transactions between Clearstream Luxembourg Participants through electronic book-entry changes in accounts of Clearstream Luxembourg Participants, thereby eliminating the need for physical movement of certificates.

        Clearstream Luxembourg provides Clearstream Luxembourg Participants with, among other things, services for safekeeping, administration, clearance and establishment of internationally traded securities and securities lending and borrowing. Clearstream Luxembourg interfaces with domestic markets in several countries. As a professional depositary, Clearstream Luxembourg is subject to regulation by the Luxembourg Monetary Institute. Clearstream Luxembourg Participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, and may include the initial purchasers. Indirect access to Clearstream Luxembourg is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream Luxembourg Participant either directly or indirectly.

        Distributions with respect to notes held beneficially through Clearstream Luxembourg will be credited to cash accounts of Clearstream Luxembourg Participants in accordance with its rules and procedures to the extent received by the U.S. depositary for Clearstream Luxembourg.

         Euroclear.    Euroclear was created in 1968 to hold securities for participants of Euroclear ("Euroclear Participants") and to clear and settle transactions between Euroclear Participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear includes various other services, including securities lending and borrowing and interfaces with domestic markets in several markets in several countries. Euroclear is operated by Euroclear Bank S.A./N.V. (the "Euroclear Operator"), under contract with Euro-clear Clearance Systems S.C., a Belgian cooperative corporation (the "Cooperative"). All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not the Cooperative. The Cooperative establishes policy for Euroclear on

49



behalf of Euroclear Participants. Euroclear Participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the initial purchasers. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly.

        The Euroclear Operator is regulated and examined by the Belgian Banking Commission. Distributions of principal and interest with respect to notes held through Euroclear will be credited to the cash accounts of Euroclear participants in accordance with the relevant system's rules and procedures, to the extent received by such system's depositary.

        Links have been established among DTC, Clearstream Luxembourg and Euroclear to facilitate the initial issuance of the notes and cross-market transfers of the notes associated with secondary market trading. DTC will be linked indirectly to Clearstream Luxembourg and Euroclear through the DTC accounts of their respective U.S. depositaries.

         Book-Entry Procedures.    We expect that, pursuant to procedures established by DTC:

        The laws of some jurisdictions may require that some purchasers of notes take physical delivery of those notes in definitive form. Accordingly, the ability to transfer beneficial interests in notes represented by a global note to those Persons may be limited. In addition, because DTC can act only on behalf of its participants, who in turn act on behalf of Persons who hold interests through participants, the ability of a Person holding a beneficial interest in a global note to pledge or transfer that interest to Persons or entities that do not participate in DTC's system, or to otherwise take actions in respect of that interest, may be affected by the lack of a physical note in respect of that interest. So long as DTC or its nominee is the registered owner of a global note, DTC or that nominee, as the case may be, will be considered the sole legal owner or holder of the notes represented by that global note for all purposes of the notes and the indenture. Except as provided below, owners of beneficial interests in a global note (1) will not be entitled to have the notes represented by that global note registered in their names, (2) will not receive or be entitled to receive physical delivery of certificated notes and (3) will not be considered the owners or holders of the notes represented by that beneficial interest under the indenture for any purpose, including with respect to the giving of any direction, instruction or approval to the Trustee. Accordingly, each holder owning a beneficial interest in a global note must rely on the procedures of DTC and, if that holder is not a participant or an indirect participant, on the procedures of the participant through which that holder owns its interest, to exercise any rights of a holder of notes under the indenture or that global note. We understand that under existing industry practice, in the event that we request any action of holders of notes, or a holder that is an owner of a beneficial interest in a global note desires to take any action that DTC, as the holder of that global note, is entitled to take, DTC would authorize the participants to take that action and the participants would authorize holders owning through those participants to take that action or would otherwise act upon the instruction of those holders. Neither we nor the Trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of notes by DTC, or for maintaining, supervising or reviewing any records of DTC relating to the notes.

        Beneficial interests in the global notes may not be exchanged for certificated notes. However, if DTC notifies us that it is unwilling to be a depositary for the global notes or ceases to be a clearing

50



agency or if we so elect or if there is an Event of Default under the notes, DTC will exchange the global notes for certificated notes which it will distribute to its participants.

        Payments on a global note will be payable by the Trustee to or at the direction of DTC or its nominee in its capacity as the registered holder of the global note under the indenture. Under the terms of the indenture, we and the Trustee may treat the persons in whose names the notes, including the global notes, are registered as the owners thereof for the purpose of receiving payment thereon and for any and all other purposes whatsoever. Accordingly, neither we nor the Trustee has or will have any responsibility or liability for the payment of those amounts to owners of beneficial interests in a global note. Payments by the participants and the indirect participants to the owners of beneficial interests in a global note will be governed by standing instructions and customary industry practice and will be the responsibility of the participants and indirect participants and not of DTC.

        Transfers between participants in DTC will be effected in accordance with DTC's procedures, and will be settled in same-day funds. Transfers between participants in Euroclear or Clearstream Luxembourg will be effected in the ordinary way in accordance with their respective rules and operating procedures.

        Cross-market transfers between the participants in DTC, on the one hand, and Euroclear or Clearstream Luxembourg participants, on the other hand, will be effected through DTC in accordance with DTC's rules on behalf of Euroclear or Clearstream Luxembourg, as the case may be, by its respective depositary. However, those cross-market transactions will require delivery of instructions to Euroclear or Clearstream Luxembourg, 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 Luxembourg, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant global notes in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream Luxembourg participants may not deliver instructions directly to the depositaries for Euroclear or Clearstream Luxembourg.

        Although we understand that DTC, Euroclear and Clearstream Luxembourg have agreed to the foregoing procedures to facilitate transfers of interests in the global notes among participants in DTC, Euroclear and Clearstream Luxembourg, such organizations are under no obligation to perform or to continue to perform those procedures, and those procedures may be discontinued at any time. Neither we nor the Trustee will have any responsibility for the performance by DTC, Euroclear or Clearstream Luxembourg or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

Same-Day Settlement and Payment

        We will make payments in respect of the notes represented by the global notes (including principal and interest) by wire transfer of immediately available funds to the accounts specified by the global note holder. We will make all payments of principal and interest with respect to certificated notes, if any, by wire transfer of immediately available funds to the accounts specified by the holders of the certificated notes or, if no such account is specified, by mailing a check to each such holder's registered address.

        Because of time zone differences, the securities account of a Euroclear or Clearstream Luxembourg participant purchasing an interest in a global note from a participant in DTC will be credited, and any such crediting will be reported to the relevant Euroclear or Clearstream Luxembourg participant, during the securities settlement processing day (which must be a business day for Euroclear and Clearstream Luxembourg) immediately following the settlement date of DTC. DTC has advised us that cash received in Euroclear or Clearstream Luxembourg as a result of sales of interests in a global

51



note by or through a Euroclear or Clearstream Luxembourg 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 Luxembourg cash account only as of the business day for Euroclear or Clearstream Luxembourg following DTC's settlement date.

        None of the Company, the Trustee or any applicable paying agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial interests in a global note, or for maintaining, supervising or reviewing any records.

52



CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE
EXCHANGE OFFER

        The exchange of outstanding notes for exchange notes in the exchange offer will not constitute a taxable event to holders for U.S. federal income tax purposes. Consequently, no gain or loss will be recognized by a holder upon receipt of an exchange note, the holding period of the exchange note will include the holding period of the outstanding note exchanged therefor and the basis of the exchange note will be the same as the basis of the outstanding note immediately before the exchange.

        In any event, persons considering the exchange of outstanding notes for exchange notes should consult their own tax advisors concerning the U.S. federal income tax consequences in light of their particular situations as well as any consequences arising under the laws of any other taxing jurisdiction.


PLAN OF DISTRIBUTION

        Each broker-dealer that receives exchange notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of the 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 outstanding notes where the outstanding notes were acquired as a result of market-making activities or other trading activities. To the extent any such broker-dealer participates in the exchange offer, we have agreed that for a period of up to 90 days we will use our reasonable best efforts to make this prospectus, as amended or supplemented, available to such broker-dealer for use in connection with any such resale, and will deliver as many additional copies of this prospectus and each amendment or supplement to this prospectus and any documents incorporated by reference in this prospectus as such broker-dealer may reasonably request.

        We will not receive any proceeds from any sale of exchange notes by broker-dealers. Exchange notes received by broker-dealers for their own accounts pursuant to the exchange offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the exchange notes or a combination of these methods of resale, at market prices prevailing at the time of resale, at prices related to the prevailing market prices or negotiated prices. Any 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 broker-dealer or the purchasers of any 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 the exchange notes may be deemed to be an "underwriter" within the meaning of the Securities Act and any profit on any resale of exchange notes and any commissions or concessions received by these 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.

        We have agreed to pay all expenses incident to the exchange offer and will indemnify the holders of outstanding notes, including any broker-dealers, against certain liabilities, including liabilities under the Securities Act.

53



LEGAL MATTERS

        The validity of the exchange notes will be passed on for us by Simpson Thacher & Bartlett LLP, New York, New York, and, with respect to matters of Minnesota law, by Robins, Kaplan, Miller & Ciresi L.L.P., Minneapolis, Minnesota.


EXPERTS

        The consolidated financial statements of Best Buy Co., Inc. as of March 1, 2008 and March 3, 2007 and for each of the three years in the period ended March 1, 2008, the related financial statement schedule and the report on the effectiveness of internal control over financial reporting as of March 1, 2008 incorporated in this prospectus by reference from the Annual Report on Form 10-K of Best Buy Co., Inc. for the year ended March 1, 2008, have been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their reports which are incorporated by reference herein, which reports (1) express an unqualified opinion on the consolidated financial statements and financial statement schedule and include an explanatory paragraph relating to Best Buy Co., Inc.'s adoption of Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes—an Interpretation of FASB Statement No. 109 and (2) express an unqualified opinion on the effectiveness of internal control over financial reporting, and have been so incorporated in reliance upon the reports of such firm given their authority as experts in accounting and auditing.

        The consolidated non-statutory financial statements of Best Buy Europe Distributions Limited as of and for the 52 weeks ended March 29, 2008 incorporated in this prospectus by reference from the Current Report on Form 8-K/A of Best Buy Co., Inc. filed on September 12, 2008, have been audited by Deloitte LLP, an independent registered public accounting firm, as stated in their report which is incorporated by reference herein, which report expresses an unqualified opinion except for the omission of comparative financial information and includes an explanatory paragraph that notes that the financial statements have been prepared from the separate records maintained by the Retail and Distribution business of The Carphone Warehouse Group PLC and may not necessarily be indicative of the conditions that would have existed or the results of operations if the business had been operated as an unaffiliated company, and have been so incorporated in reliance upon the report of such firm given their authority as experts in accounting and auditing.

Independence of Deloitte & Touche LLP

        Beginning in fiscal 2006, we engaged Deloitte & Touche LLP as our independent registered public accounting firm with respect to our financial statements. In September 2008, Deloitte & Touche LLP advised us that they believed an advisory partner on Deloitte & Touche LLP's audit engagement team had entered into trades involving our securities on multiple occasions during the period of Deloitte & Touche LLP's engagement. SEC rules require that we file annual financial statements that are audited by an independent registered public accounting firm. SEC rules also provide that when a partner serving in a capacity such as that of this advisory partner has an investment in securities of an audit client the audit firm is not considered independent with respect to that client.

        This individual had served as the advisory partner on the audit engagement team from the commencement of Deloitte & Touche LLP's engagement in fiscal 2006 until September 2008. The advisory partner is no longer an active partner at Deloitte & Touche LLP. The audit partner heading the audit engagement team had responsibility for all substantive issues with respect to the planning, scope and conduct of Deloitte & Touche LLP's audit of our company, while the former advisory partner was responsible for client relationship management, industry matters and service assessment.

        The former advisory partner attended some, but not all, audit committee meetings. At these meetings, he reviewed with the committee reports of the annual inspection of Deloitte & Touche LLP

54



conducted by the Public Company Accounting Oversight Board as well as Deloitte & Touche LLP's annual client service assessments. The former advisory partner also met occasionally with members of our management or our audit committee. His role was to advise on industry matters and to maintain the relationship between Deloitte & Touche LLP and us. He did not review substantive audit matters with management or the committee. The former advisory partner attended our annual meetings of shareholders as one of the Deloitte & Touche LLP representatives attending those meetings. Neither the former advisory partner nor any other Deloitte & Touche LLP representative spoke at any of these shareholder meetings and no questions were asked of Deloitte & Touche LLP.

        Deloitte & Touche LLP reported to us the results of its investigation of the involvement of the former advisory partner in actual audit matters, including review of its audit-related files and logs and interviews of other members of the audit engagement team. Deloitte & Touche LLP also reported to us the steps taken in its investigation and its conclusions and provided supporting materials to us. At the direction of our audit committee, we also conducted an investigation into the extent of any involvement of the former advisory partner in actual audit matters. We retained outside counsel to direct and assist in this investigation. Internal counsel conducted interviews with members and certain former members of our senior management and audit committee that had contact with the former advisory partner, including our chief financial officer and our chief accounting officer. Outside and internal counsel reviewed summaries of the interviews and related documentation, including the minutes of all of our board of directors and board committee meetings in which the former advisory partner participated, our electronic records and communications identified as pertaining to the former advisory partner, and supporting materials provided by Deloitte & Touche LLP.

        Following these investigations, Deloitte & Touche LLP and our management advised our audit committee that no evidence was discovered that indicated that the former advisory partner had any substantive responsibility for or role in the conduct of the audit. Deloitte & Touche LLP delivered a letter to our audit committee stating that, despite the trades in our securities by their former advisory partner and the resulting violation of the SEC's independence rules, the former advisory partner had not exercised any influence over the conduct of the audit or its conclusions with respect to the audit or accounting consultations, that the objectivity of the persons responsible for the actual conduct of the audit had not been affected by the former advisory partner's actions, and that Deloitte & Touche LLP's independence was not impaired.

        Based on the foregoing and our audit committee's understanding of the application of the relevant SEC rules, our audit committee accepted Deloitte & Touche LLP's conclusion and letter regarding its independence and unanimously concluded that, based on all of the facts and circumstances known to the audit committee, Deloitte & Touche LLP's independence was not impaired with respect to any of our financial statements covering periods during which the former advisory partner was a member of Deloitte & Touche LLP's audit engagement team, including the current fiscal period. Deloitte & Touche LLP and we have reported our respective conclusions regarding this matter to the SEC.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.    INDEMNIFICATION OF DIRECTORS AND OFFICERS

        The registrant is subject to the Minnesota Business Corporation Act, Minnesota Statutes, Chapter 302A. Minnesota Statutes, Section 302A.521, subd. 2, provides that a corporation shall indemnify a person made or threatened to be made a party to a proceeding by reason of the former or present official capacity of the person with respect to the corporation against judgments, penalties, fines, including, without limitation, excise taxes assessed against the person with respect to an employee benefit plan, settlements, and reasonable expenses, including attorneys' fees and disbursements, incurred by the person in connection with the proceeding, if, with respect to the acts or omissions of the person complained of in the proceeding, the person: (1) has not been indemnified therefor by another organization or employee benefit plan; (2) acted in good faith; (3) received no improper personal benefit and Section 302A.255 (with respect to director conflicts of interest), if applicable, has been satisfied; (4) in the case of a criminal proceeding, had no reasonable cause to believe the conduct was unlawful; and (5) in the case of acts or omissions occurring in the person's official capacity for the corporation, reasonably believed that the conduct was in the best interests of the corporation, or, in the case of acts or omissions occurring in the person's official capacity for another affiliated organization, reasonably believed that the conduct was not opposed to the best interests of the corporation. If the person's acts or omissions complained of in the proceeding relate to conduct as a director, officer, trustee, employee, or agent of an employee benefit plan, the conduct is not considered to be opposed to the best interests of the corporation if the person reasonably believed that the conduct was in the best interests of the participants or beneficiaries of the employee benefit plan.

        In addition, the registrant's articles of incorporation provide that a director of the registrant shall not be personally liable to the registrant or its shareholders for monetary damages for breach of fiduciary duty as a director except for liability (1) for any breach of the director's duty of loyalty to the registrant or its shareholders; (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (3) under Minnesota Statutes, Section 302A.559, for improperly paying a dividend or approving a stock repurchase; (4) under Minnesota Statutes, Section 80A.76, for violating the securities registration or anti-fraud provisions; (5) for any transaction from which the director derived an improper personal benefit; or (6) for acts or omissions occurring prior to the date when the relevant provision of the articles of incorporation became effective. The registrant's articles of incorporation do not limit directors' liability for violations of the federal securities laws. The registrant's articles of incorporation are consistent with the Minnesota Business Corporation Act and if such act is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the registrant would be eliminated or limited to the fullest extent permitted by Minnesota law.

        The registrant has directors' and officers' liability insurance which is subject to various deductibles and exclusions from coverage.

ITEM 22.    UNDERTAKINGS

        (a)   The undersigned registrant hereby undertakes:

II-2


        (b)   The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11 or 13 of Form S-4, within one business day of receipt of such request, and to send the incorporated documents by first class mail or equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

        (c)   The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

        (d)   Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers, or controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrants of expenses incurred or paid by a director, officer or controlling person of the registrants in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrants will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

        (e)   The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
