[1]	Income tax benefit for the three months ended November 2, 2013 includes a $16 million benefit related to the impairment of our investment in Best Buy Europe, partially offset by $(6) million of expense related to a tax allocation between continuing and discontinued operations. The fiscal 2014 effective tax rate for discontinued operations differs from the statutory tax rate primarily due to the tax allocation, restructuring charges and the impairment of our investment in Best Buy Europe. The restructuring charges and impairment generally included minimal related tax benefit. The deferred tax assets related to the restructuring charges generally resulted in an increase in the valuation allowance in an equal amount, while the investment impairment is generally not tax deductible.

Basis of Presentation	'
	Basis of Presentation
	Unless the context otherwise requires, the use of the terms “Best Buy,” “we,” “us,” and “our” in these Notes to Condensed Consolidated Financial Statements refers to Best Buy Co., Inc. and its consolidated subsidiaries.
	In the opinion of management, the accompanying condensed consolidated financial statements contain all adjustments necessary for a fair presentation as prescribed by accounting principles generally accepted in the United States (“GAAP”). All adjustments were comprised of normal recurring adjustments, except as noted in these Notes to Condensed Consolidated Financial Statements.
	Sale of Best Buy Europe
	During the first quarter of fiscal 2014, we entered into a definitive agreement with Carphone Warehouse Group plc ("CPW") to sell our 50% ownership interest in Best Buy Europe to CPW. On June 26, 2013, the sale was completed. As a result, beginning in the first quarter of fiscal 2014, the results of Best Buy Europe for all periods have been presented as discontinued operations. See Note 2, Discontinued Operations, for further information.
	On June 21, 2013, we filed a Current Report on Form 8-K (the “June 21st Form 8-K”) to recast certain financial information included in our Transition Report on Form 10-K for the transition period from March 4, 2012, to February 2, 2013, to reflect the results of Best Buy Europe as discontinued operations.
	Description of Business
	Historically, we have realized more of our revenue and a large portion of our earnings in the fiscal fourth quarter, which includes the majority of the holiday shopping season in the U.S., Canada and Mexico, than in any other fiscal quarter. Due to the seasonal nature of our business, interim results are not necessarily indicative of results for the entire fiscal year. The interim financial statements and the related notes in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and related notes included in our Transition Report on Form 10-K for the fiscal year ended February 2, 2013, and the recast financial information included in the June 21st Form 8-K. The first nine months of fiscal 2014 and fiscal 2013 included 39 weeks and 40 weeks, respectively.
	Beginning in the first quarter of fiscal 2013, we changed our fiscal year-end from the Saturday nearest the end of February to the Saturday nearest the end of January. As a result of this change, our fiscal year 2013 was an 11-month transition period ending on February 2, 2013. The results for the nine months ended November 3, 2012 include our fiscal month ended March 3, 2012, for operations that are not reported on a lag (primarily our Domestic segment and Canadian operations), which were also included in our results for the fiscal year ended March 3, 2012, included in our fiscal 2012 Form 10-K. See Note 2, Fiscal Year-end Change, in the Notes to Consolidated Financial Statements included in our Transition Report on Form 10-K for the fiscal year ended February 2, 2013, and the recast financial information included in the June 21st Form 8-K, for additional information regarding our fiscal year-end change.
	In order to align our fiscal reporting periods and comply with statutory filing requirements in certain foreign jurisdictions, we consolidate the financial results of our China and Mexico operations on a one-month lag. Our policy is to accelerate recording the effect of events occurring in the lag period that significantly affect our consolidated financial statements. No such events were identified for this period.
	In preparing the accompanying condensed consolidated financial statements, we evaluated the period from November 3, 2013, through the date the financial statements were issued, for material subsequent events requiring recognition or disclosure. No such events were identified for this period.

	Discontinued Operations
	On June 26, 2013, we completed the sale of our 50% ownership interest in Best Buy Europe to CPW in return for the following consideration upon closing: net cash of £341 million ($526 million); £80 million ($123 million) of ordinary shares of CPW; £25 million ($39 million), plus 2.5% interest, to be paid by CPW on June 26, 2014; and £25 million ($39 million), plus 2.5% interest, to be paid by CPW on June 26, 2015. We subsequently sold the ordinary shares of CPW for $123 million on July 3, 2013.
	The composition of assets and liabilities disposed of on June 26, 2013, as a result of the sale of Best Buy Europe was as follows ($ in millions):
		26-Jun-13
	Cash and cash equivalents	$	597
	Receivables	1,295

	Accounts payable	790
	Short-term debt	973
	Other current liabilities	1,145
	Long-term liabilities	65
	Total liabilities	2,973
	Discontinued operations are comprised of: (i) Napster operations within our Domestic segment; (ii) large-format Best Buy branded store operations in China within our International segment; and (iii) Best Buy Europe operations within our International segment. The presentation of discontinued operations has been retrospectively applied to all prior periods presented.
	The financial results of discontinued operations for the three and nine months ended November 2, 2013, and November 3, 2012, were as follows ($ in millions):

	(1)	See Note 6, Restructuring Charges, for further discussion of the restructuring charges associated with discontinued operations.
	(2)	Income tax benefit for the three months ended November 2, 2013 includes a $16 million benefit related to the impairment of our investment in Best Buy Europe, partially offset by $(6) million of expense related to a tax allocation between continuing and discontinued operations. The fiscal 2014 effective tax rate for discontinued operations differs from the statutory tax rate primarily due to the tax allocation, restructuring charges and the impairment of our investment in Best Buy Europe. The restructuring charges and impairment generally included minimal related tax benefit. The deferred tax assets related to the restructuring charges generally resulted in an increase in the valuation allowance in an equal amount, while the investment impairment is generally not tax deductible.

	Debt Securities
	Our debt securities are comprised of auction rate securities (“ARS”). At November 2, 2013, our ARS portfolio of three investments had a par value of $10 million and a fair value of $9 million. We sold $7 million of ARS at par during the third quarter of fiscal 2014. We do not intend to sell our remaining ARS until we can recover the full principal amount. In addition, we do not believe it is more likely than not that we would be required to sell our remaining ARS until we can recover the full principal amount based on our other sources of liquidity. Our ARS portfolio had an immaterial impact on accumulated other comprehensive income at November 2, 2013, February 2, 2013, and November 3, 2012.
	Marketable Equity Securities
	We invest in marketable equity securities and classify them as available-for-sale. Investments in marketable equity securities are classified as non-current assets within equity and other investments in our Condensed Consolidated Balance Sheets and are reported at fair value based on quoted market prices. Our investments in marketable equity securities were $10 million, $27 million, and $3 million at November 2, 2013, February 2, 2013, and November 3, 2012, respectively. We review all investments for other-than-temporary impairment at least quarterly or as indicators of impairment exist. The total unrealized gain, net of tax, included in accumulated other comprehensive income was immaterial at November 2, 2013, February 2, 2013, and November 3, 2012, respectively.
	Other Investments
	The aggregate carrying values of investments accounted for using the cost method at November 2, 2013, February 2, 2013, and November 3, 2012 were $22 million, $38 million, and $67 million, respectively.

	Fair Value Measurements
	Fair value is the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. To measure fair value, we use a three-tier valuation hierarchy based upon observable and non-observable inputs:
	Level 1 — Unadjusted quoted prices that are available in active markets for the identical assets or liabilities at the measurement date.
	Level 2 — Significant other observable inputs available at the measurement date, other than quoted prices included in Level 1, either directly or indirectly, including:
	•	Quoted prices for similar assets or liabilities in active markets;
	•	Quoted prices for identical or similar assets in non-active markets;
	•	Inputs other than quoted prices that are observable for the asset or liability; and
	•	Inputs that are derived principally from or corroborated by other observable market data.
	Level 3 — Significant unobservable inputs that cannot be corroborated by observable market data and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions.
	Assets and Liabilities Measured at Fair Value on a Recurring Basis
	The fair value hierarchy requires the use of observable market data when available. In instances where the inputs used to measure fair value fall into different levels of the fair value hierarchy, the fair value measurement has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. Our assessment of the significance of a particular item to the fair value measurement in its entirety requires judgment, including the consideration of inputs specific to the asset or liability. The following tables set forth by level within the fair value hierarchy, our financial assets and liabilities that were accounted for at fair value on a recurring basis at November 2, 2013, February 2, 2013, and November 3, 2012, according to the valuation techniques we used to determine their fair values ($ in millions).

The following methods and assumptions were used to estimate the fair value of each class of financial instrument:
Money Market Funds.  Our money market fund investments that are traded in an active market were measured at fair value using quoted market prices and, therefore, were classified as Level 1.
Foreign Currency Derivative Instruments.  Comprised primarily of foreign currency forward contracts and foreign currency swap contracts, our foreign currency derivative instruments were measured at fair value using readily observable market inputs, such as quotations on forward foreign exchange points and foreign interest rates. Our foreign currency derivative instruments were classified as Level 2 as these instruments are custom, over-the-counter contracts with various bank counterparties that are not traded in active markets.
Auction Rate Securities.  Our investments in ARS were classified as Level 3 as quoted prices were unavailable due to events described in Note 3, Investments. Due to limited market information, we utilized a discounted cash flow (“DCF”) model to derive an estimate of fair value. The unobservable inputs and assumptions we used in preparing the DCF model included estimates with respect to the amount and timing of future interest and principal payments, forward projections of the interest rate benchmarks, the probability of full repayment of the principal considering the credit quality and guarantees in place, and the rate of return required by investors to own such securities given the current liquidity risk associated with ARS. Changes in these unobservable inputs are not likely to have a significant impact on the fair value measurement of our ARS.
Marketable Equity Securities.  Our marketable equity securities were measured at fair value using quoted market prices. They were classified as Level 1 as they trade in active markets for which closing stock prices are readily available.
Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis
Assets and liabilities that are measured at fair value on a nonrecurring basis relate primarily to our tangible fixed assets, goodwill and intangible assets, which are remeasured when the fair value is below carrying value on our Condensed Consolidated Balance Sheets. For these assets, we do not periodically adjust carrying value to fair value except in the event of impairment. When we determine that impairment has occurred, the carrying value of the asset is reduced to fair value and the difference is recorded within operating income in our Consolidated Statements of Earnings.
With the exception of fixed asset impairments associated with our agreement to sell our interest in Best Buy Europe and our restructuring activities described in Note 6, Restructuring Charges, we had no significant remeasurements of such assets or liabilities to fair value during the nine months ended November 2, 2013, and November 3, 2012.
The following table summarizes the fair value remeasurements recorded during the nine months ended November 2, 2013, and November 3, 2012 ($ in millions):
	Nine Months Ended					Nine Months Ended

(1)	Property and equipment and tradename impairments associated with discontinued operations are recorded within gain (loss) from discontinued operations in our Consolidated Statements of Earnings.
(2)	Includes the $175 million impairment to write down the book value of our investment in Best Buy Europe to fair value. Upon completion of the sale of Best Buy Europe as described in Note 2, Discontinued Operations, the remaining net carrying values of all assets have been reduced to zero.
The fair value remeasurements included in the table above were based on significant unobservable inputs (Level 3). Fixed asset and tradename fair values were derived using a DCF model to estimate the present value of net cash flows that the asset or asset group was expected to generate. The key inputs to the DCF model generally included our forecasts of net cash generated from revenue, sales proceeds, expenses and other significant cash outflows, such as capital expenditures, as well as an appropriate discount rate. In the case of these specific assets, for which their impairment was the result of restructuring activities, no future cash flows have been assumed as the assets will cease to be used and expected sale values are nominal.
Fair Value of Financial Instruments
Our financial instruments, other than those presented in the disclosures above, include cash, receivables, other investments, accounts payable, other payables, and short- and long-term debt. The fair values of cash, receivables, accounts payable, other payables, and short-term debt approximated carrying values because of the short-term nature of these instruments. If these instruments were measured at fair value in the financial statements, they would be classified as Level 1 in the fair value hierarchy. Fair values for other investments held at cost are not readily available, but we estimate that the carrying values for these investments approximate fair value. See Note 7, Debt, for information about the fair value of our long-term debt.

	In the fourth quarter of fiscal 2013, we began implementing initiatives intended to reduce costs and improve operating performance. These initiatives included focusing on core business activities, reducing headcount and optimizing our real estate portfolio. These cost reduction initiatives represent one of the six Renew Blue priorities for fiscal 2014. We incurred $52 million of restructuring charges related to Renew Blue initiatives during the first nine months of fiscal 2014, primarily comprised of employee termination benefits, investment impairments, facility closure costs, and property and equipment impairments. We expect to continue to implement Renew Blue initiatives throughout fiscal 2014, as we further analyze our operations and strategies.
	All restructuring charges related to this program are from continuing operations and are presented in restructuring charges in our Consolidated Statements of Earnings. The composition of the restructuring charges we incurred for this program in the nine months ended November 2, 2013, as well as the cumulative amount incurred through November 2, 2013, was as follows ($ in millions):

	Fiscal 2013 Europe Restructuring
	In the third quarter of fiscal 2013, we initiated a series of actions to restructure our Best Buy Europe operations in our International segment intended to improve operating performance. All restructuring charges related to this program are reported within gain (loss) from discontinued operations in our Consolidated Statements of Earnings as a result of the sale of our 50% ownership interest in Best Buy Europe. Refer to Note 2, Discontinued Operations. We incurred $95 million of restructuring charges in the first nine months of fiscal 2014, consisting primarily of property and equipment impairments and employee termination benefits. In the first nine months of fiscal 2013, we incurred $2 million of restructuring charges related to employee termination benefits. Given the sale of Best Buy Europe, we do not expect to incur additional restructuring charges related to this program.

Fiscal 2013 U.S. Restructuring
In the first quarter of fiscal 2013, we initiated a series of actions to restructure operations in our Domestic segment intended to improve operating performance. The actions included closure of 49 large-format Best Buy branded stores in the U.S. and changes to the store and corporate operating models. The costs of implementing the changes are primarily comprised of facility closure costs, employee termination benefits, and property and equipment (primarily store fixtures) impairments. We recognized a reduction to restructuring charges of $8 million in the nine months ended November 2, 2013, as a result of the buyout of a lease for less than the remaining vacant space liability. In the nine months ended November 3, 2012, we incurred $258 million of charges consisting primarily of facility closure and other costs, termination benefits, and property and equipment impairments. We do not expect to incur further material restructuring charges related to this program, with the exception of lease payments for vacated stores which will continue until leases expire or are terminated.
The restructuring charges related to our fiscal U.S. 2013 restructuring activities are from continuing operations and are presented in restructuring charges in our Consolidated Statements of Earnings. The composition of the restructuring charges we incurred for this program in the nine months ended November 2, 2013, and November 3, 2012, as well as the cumulative amount incurred through November 2, 2013, was as follows ($ in millions):

Fiscal 2012 Restructuring
In the third quarter of fiscal 2012, we implemented a series of actions to restructure operations in our Domestic and International segments. The actions within our Domestic segment included a decision to modify our strategy for certain mobile broadband offerings. In our International segment, we closed our large-format Best Buy branded stores in the U.K. and impaired certain information technology assets supporting the restructured operations. All restructuring charges directly related to the large-format Best Buy branded stores in the U.K. are reported within gain (loss) from discontinued operations in our Consolidated Statements of Earnings. Refer to Note 2, Discontinued Operations. All other restructuring charges related to this program are from continuing operations and are presented in restructuring charges in our Consolidated Statements of Earnings.
We incurred $5 million of charges related to this program in the first nine months of fiscal 2014, representing a change in sublease assumptions. In the first nine months of fiscal 2013, we incurred $1 million of charges, comprised primarily of facility closure and other costs. We do not expect to incur further material restructuring charges related to this program in either our Domestic or International segments, as we have substantially completed these restructuring activities.
The composition of the restructuring charges we incurred for this program in the nine months ended November 2, 2013, and November 3, 2012, as well as the cumulative amount incurred through November 2, 2013, was as follows ($ in millions):

Fiscal 2011 Restructuring
In the fourth quarter of fiscal 2011, we implemented a series of actions to restructure operations in our Domestic and International segments in order to improve performance and enhance customer service. The restructuring actions included plans to improve supply chain and operational efficiencies in our Domestic segment's operations, primarily focused on modifications to our distribution channels and exit from certain digital delivery services within our entertainment product category. During the first nine months of fiscal 2013, we recorded a net reduction to restructuring charges of $10 million, which related primarily to our Domestic segment. The net reduction was largely the result of a gain recorded on the sale of a previously impaired distribution facility and equipment during the first quarter of fiscal 2013 (previously impaired through restructuring charges), partially offset by charges associated with the exit from certain digital delivery services within our entertainment product category. We have completed activities under this plan.

	(1)	Short-term debt associated with the Europe revolving credit facility is related to our Best Buy Europe operations, which we sold on June 26, 2013, as described in Note 2, Discontinued Operations.
	U.S. Revolving Credit Facility
	On June 25, 2013, we entered into a $500 million 364-day senior unsecured revolving credit facility agreement (the "364-Day Facility Agreement") with a syndicate of lenders. The 364-Day Facility Agreement replaces the previous $1.0 billion senior unsecured revolving credit facility with a syndicate of banks, including JPMorgan acting as administrative agent, which was originally scheduled to expire on August 30, 2013, but was terminated on June 25, 2013.
	The interest rate under the 364-Day Facility Agreement is variable and is determined at the registrant's option as either: (i) the sum of (a) the greatest of (1) JPMorgan's prime rate, (2) the federal funds rate plus 0.5%, and (3) the one-month London Interbank Offered Rate (“LIBOR”) plus 1%, and (b) a variable margin rate (the “ABR Margin”); or (ii) the LIBOR plus a variable margin rate (the “LIBOR Margin”). In addition, a facility fee is assessed on the commitment amount. The ABR Margin, LIBOR Margin and the facility fee are based upon our current senior unsecured debt rating by Standard and Poor's Rating Services and Moody's Investors Services, Inc. Under the 364-Day Facility Agreement, the ABR Margin ranges from 0.0% to 0.6%, the LIBOR Margin ranges from 0.925% to 1.6%, and the facility fee ranges from 0.075% to 0.275%.

	2013 Notes
	We retired our $500 million principal amount of notes plus accrued interest when they matured on July 15, 2013, using available cash.
	2018 Notes
	On July 16, 2013, we completed the sale of $500 million principal amount of notes due August 1, 2018 (the “2018 Notes”). The 2018 Notes bear interest at a fixed rate of 5.00% per year, payable semi-annually on February 1 and August 1 of each year, beginning on February 1, 2014. Net proceeds from the sale of the 2018 Notes were $495 million, after underwriting and issue discounts totaling $5 million.
	We may redeem some or all of the 2018 Notes at any time, at a redemption price equal to the greater of (1) 100% of the principal amount of the 2018 Notes to be redeemed and (2) the sum of the present values of each remaining scheduled payment of principal and interest on the 2018 Notes to be redeemed discounted to the redemption date on a semi-annual basis at the comparable Treasury Rate plus 50 basis points.
	The 2018 Notes are unsecured and unsubordinated obligations and rank equally with all of our other unsecured and unsubordinated debt. The 2018 Notes contain covenants that, among other things, limit our ability and the ability of our subsidiaries to incur debt secured by liens and enter into sale and lease-back transactions.
	Other
	The fair value of long-term debt approximated $1,717 million, $1,652 million, and $1,635 million at November 2, 2013, February 2, 2013, and November 3, 2012, respectively, based primarily on the market prices quoted from external sources, compared with carrying values of $1,669 million, $1,700 million, and $1,702 million, respectively. If long-term debt was measured at fair value in the financial statements, it would be classified primarily as Level 1 in the fair value hierarchy.

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
Derivative Instruments	'
	Derivative Instruments
	We manage our transaction exposure to certain market-based risks through the use of foreign currency derivative instruments. Our objective in holding derivatives is to reduce the volatility of net earnings and cash flows associated with changes in foreign currency exchange rates. We do not hold or issue derivative financial instruments for trading or speculative purposes. In addition, we have no derivatives that have credit risk-related contingent features, and we mitigate our credit risk by engaging with major financial institutions as our counterparties.
	Derivatives Not Designated as Hedging Instruments
	Derivatives not designated as hedging instruments include foreign currency forward contracts used to manage the impact of fluctuations in foreign currency exchange rates relative to recognized receivable and payable balances denominated in non-functional currencies, and on certain forecast inventory purchases denominated in non-functional currencies. The contracts generally have terms of up to 12 months. These derivative instruments are not designated in hedging relationships and, therefore, we record gains and losses on these contracts directly to net earnings. At November 2, 2013, the notional amount of these instruments was $138 million and the effect of these instruments on our Consolidated Statements of Earnings for the three and nine months ended November 2, 2013, recognized in selling, general and administrative expenses was a $3 million loss and $3 million gain, respectively.
	In conjunction with our agreement to sell our 50% ownership interest in Best Buy Europe as described in Note 2, Discontinued Operations, we entered into a deal-contingent foreign currency forward contract to hedge £455 million of the total £471 million of net proceeds. The contract was settled in cash following the completion of the sale on June 26, 2013. This instrument had no effect on the Consolidated Statements of Earnings in the three months ended November 2, 2013, and a $2 million loss recognized in gain (loss) from discontinued operations in the nine months ended November 2, 2013.
	Summary of Derivative Balances
	The following table presents the notional amounts of our foreign currency exchange contracts at November 2, 2013, February 2, 2013, and November 3, 2012 ($ in millions):

Earnings Per Share [Abstract]	'
Earnings per Share	'
	Earnings per Share
	We compute our basic earnings per share based on the weighted-average number of common shares outstanding and our diluted earnings per share based on the weighted-average number of common shares outstanding adjusted by the number of additional shares that would have been outstanding had potentially dilutive common shares been issued. Potentially dilutive securities include stock options, nonvested share awards and shares issuable under our employee stock purchase plan. Nonvested market-based share awards and nonvested performance-based share awards are included in the average diluted shares outstanding for each period if established market or performance criteria have been met at the end of the respective periods.
	The following table presents a reconciliation of the numerators and denominators of basic and diluted earnings per share from continuing operations attributable to Best Buy Co., Inc. ($ and shares in millions):

	Diluted	$	0.12		$	(0.03	)	$	1.09		$	0.56
	The computation of weighted-average common shares outstanding, assuming dilution, excluded options to purchase 12.6 million shares of our common stock for the three months ended November 2, 2013 and options to purchase 16.4 million and 28.6 million shares of our common stock for the nine months ended November 2, 2013, and November 3, 2012, respectively. These amounts were excluded as the options’ exercise prices were greater than the average market price of our common stock for the periods presented and, therefore, the effect would be anti-dilutive (i.e., including such options would result in higher earnings per share). The calculation of the diluted loss per share for the three months ended November 3, 2012 does not include potentially dilutive securities because their inclusion would be anti-dilutive (i.e. reduce the net loss per share).

	In June 2011, our Board of Directors authorized a $5.0 billion share repurchase program. There is no expiration date governing the period over which we can repurchase shares under the June 2011 share repurchase program. For the nine months ended November 3, 2012, we repurchased 10.9 million shares of our common stock at a cost of $237 million. No shares were repurchased during the three months ended November 3, 2012, nor the three or nine months ended November 2, 2013.
	At November 2, 2013, $4.0 billion remained available for additional purchases under the June 2011 share repurchase program. Repurchased shares have been retired and constitute authorized but unissued shares. We have currently suspended our share repurchase program.

	Segments
	Our chief operating decision maker ("CODM") is our Chief Executive Officer. Our business is organized into two segments: Domestic (which is comprised of all operations within the United States and its territories) and International (which is comprised of all operations outside the United States and its territories). Our CODM has ultimate responsibility for enterprise decisions. Our CODM determines, in particular, resource allocation for, and monitors the performance of, the consolidated enterprise, the Domestic segment and the International segment. Segment managers for the Domestic segment and the International segment have responsibility for operating decisions, allocating resources and assessing performance within their respective segments. Our CODM relies on internal management reporting that analyzes enterprise and segment results to the operating income level.
	We do not aggregate our operating segments, so our operating segments also represent our reportable segments. The accounting policies of the segments are the same as those described in Note 1, Summary of Significant Accounting Policies, in the Notes to Consolidated Financial Statements included in our Transition Report on Form 10-K for the fiscal year ended February 2, 2013, and the recast financial information included in the June 21st Form 8-K.

	Contingencies
	We are involved in a number of legal proceedings. Where appropriate, we have made accruals with respect to these matters, which are reflected in our consolidated financial statements. However, there are cases where liability is not probable or the amount cannot be reasonably estimated and therefore accruals have not been made. We provide disclosure of matters where we believe it is reasonably possible the impact may be material to our consolidated financial statements.
	Securities Actions
	In February 2011, a purported class action lawsuit captioned, IBEW Local 98 Pension Fund, individually and on behalf of all others similarly situated v. Best Buy Co., Inc., et al., was filed against us and certain of our executive officers in the U.S. District Court for the District of Minnesota. This federal court action alleges, among other things, that we and the officers named in the complaint violated Sections 10(b) and 20A of the Exchange Act and Rule 10b-5 under the Exchange Act in connection with press releases and other statements relating to our fiscal 2011 earnings guidance that had been made available to the public. Additionally, in March 2011, a similar purported class action was filed by a single shareholder, Rene LeBlanc, against us and certain of our executive officers in the same court. In July 2011, after consolidation of the IBEW Local 98 Pension Fund and Rene LeBlanc actions, a consolidated complaint captioned, IBEW Local 98 Pension Fund v. Best Buy Co., Inc., et al., was filed and served. We filed a motion to dismiss the consolidated complaint in September 2011, and in March 2012, subsequent to the end of fiscal 2012, the court issued a decision dismissing the action with prejudice. In April 2012, the plaintiffs filed a motion to alter or amend the court's decision on our motion to dismiss. In October 2012, the court granted plaintiff's motion to alter or amend the court's decision on our motion to dismiss in part by vacating such decision and giving plaintiff leave to file an amended complaint, which plaintiff did in October 2012. We filed a motion to dismiss the amended complaint in November 2012 and all responsive pleadings were filed in December 2012. A hearing was held on April 26, 2013. On August 5, 2013, the court issued an order granting our motion to dismiss in part and, contrary to its March 2012 order, denying the motion to dismiss in part, holding that certain of the statements alleged to have been made were not forward looking statements and therefore were not subject to the “safe-harbor” provisions of the Private Securities Litigation Reform Act (PSLRA). We filed a Motion to Reconsider the August 5 Order and also a Motion to Certify that Order for Interlocutory Review by the Eighth Circuit Court of Appeals. Decisions on those motions are pending. We continue to believe that these allegations are without merit and intend to vigorously defend our company in this matter.
	In June 2011, a purported shareholder derivative action captioned, Salvatore M. Talluto, Derivatively and on Behalf of Best Buy Co., Inc. v. Richard M. Schulze, et al., as Defendants and Best Buy Co., Inc. as Nominal Defendant, was filed against both present and former members of our Board of Directors serving during the relevant periods in fiscal 2011 and us as a nominal defendant in the U.S. District Court for the State of Minnesota. The lawsuit alleges that the director defendants breached their fiduciary duty, among other claims, including violation of Section 10(b) of the Exchange Act and Rule 10b-5 thereunder, in failing to correct public misrepresentations and material misstatements and/or omissions regarding our fiscal 2011 earnings projections and, for certain directors, selling stock while in possession of material adverse non-public information. Additionally, in July 2011, a similar purported class action was filed by a single shareholder, Daniel Himmel, against us and certain of our executive officers in the same court. In November 2011, the respective lawsuits of Salvatore M. Talluto and Daniel Himmel were consolidated into a new action captioned, In Re: Best Buy Co., Inc. Shareholder Derivative Litigation, and a stay ordered until after a final resolution of the motion to dismiss in the consolidated IBEW Local 98 Pension Fund v. Best Buy Co., Inc., et al. case.
	The plaintiffs in the above securities actions seek damages, including interest, equitable relief and reimbursement of the costs and expenses they incurred in the lawsuits. As stated above, we believe the allegations in the above securities actions are without merit, and we intend to defend these actions vigorously. Based on our assessment of the facts underlying the claims in the above securities actions, their respective procedural litigation history, and the degree to which we intend to defend our company in these matters, the amount or range of reasonably possible losses, if any, cannot be estimated.
	Trade Secrets Action
	In February 2011, a lawsuit captioned Techforward, Inc. v. Best Buy Co., Inc., et. al. was filed against us in the U.S. District Court, Central District of California. The case alleges that we implemented our “Buy Back Plan” in February 2011 using trade secrets misappropriated from plaintiff's buyback plan that were disclosed to us during business relationship discussions and also breached both an agreement for a limited marketing test of plaintiff's buyback plan and a non-disclosure agreement related to the business discussions. In November 2012, a jury found we were unjustly enriched through misappropriation of trade secrets and awarded plaintiff $22 million. The jury also found that although we breached the subject contracts, plaintiff suffered no resulting damage. In December 2012, the court further awarded the plaintiff $5 million in exemplary damages and granted plaintiff's motion for $6 million in attorney fees and costs. We believe that the jury verdict and court awards are inconsistent with the law and the evidence offered at trial or otherwise in error. Accordingly, we appealed the resulting judgment and awards in February 2013 and our opening brief and Techforward’s opposition have been filed. We intend to vigorously pursue this appeal and contest these decisions.
	LCD Action
	On October 8, 2010, we filed a lawsuit captioned Best Buy Co., Inc., et al. v. AU Optronics Corp., et al. in the United States District Court for the Northern District of California. We allege that the defendants engaged in price fixing in violation of antitrust regulations and conspired to control the supply of TFT-LCD panels. During the second quarter of fiscal 2014, we entered into binding settlement agreements with multiple defendants. Under the terms of the settlement agreements, we will receive specified payments in accordance with specified schedules, and there are no performance obligations or other contingencies associated with our right to receive the specified payments. Settlement proceeds of $264 million were recognized during the second quarter in cost of goods sold. In addition, associated legal expenses of $35 million were recorded in selling, general and administrative expenses. As of November 2, 2013, $137 million of the gross settlement proceeds had been received, with the remaining $127 million recorded as short-term or long-term receivables.
	On July 22, 2013, trial commenced against the remaining named defendants. On September 3, 2013, a jury found that HannStar Display, Co. knowingly participated in a conspiracy to fix prices for TFT-LCD panels and found damages in the amount of $7.5 million. In addition, the jury found that Toshiba Corp. did not knowingly participate in the alleged conspiracy. We are considering all options in regard to the verdict, but we currently do not expect to receive amounts in addition to the settlements reached in prior quarters. As to HannStar, we have applied to the trial court for attorney fees, costs and disbursements. A decision on that application is pending.
	Other Legal Proceedings
	We are involved in various other legal proceedings arising in the normal course of conducting business. For such legal proceedings, we have accrued an amount that reflects the aggregate liability deemed probable and estimable, but this amount is not material to our consolidated financial position, results of operations or cash flows. Because of the preliminary nature of many of these proceedings, the difficulty in ascertaining the applicable facts relating to many of these proceedings, the variable treatment of claims made in many of these proceedings and the difficulty of predicting the settlement value of many of these proceedings, we are not able to estimate an amount or range of any reasonably possible additional losses. However, based upon our historical experience, the resolution of these proceedings is not expected to have a material effect on our consolidated financial position, results of operations or cash flows.

The fiscal 2014 effective tax rate for discontinued operations differs from the statutory tax rate primarily due to the tax allocation, restructuring charges and the impairment of our investment in Best Buy Europe. The restructuring charges and impairment generally included minimal related tax benefit. The deferred tax assets related to the restructuring charges generally resulted in an increase in the valuation allowance in an equal amount, while the investment impairment is generally not tax deductible.

See Note 6, Restructuring Charges, for further discussion of the restructuring charges associated with discontinued operations.

[2]

Income tax benefit for the three months ended November 2, 2013 includes a $16 million benefit related to the impairment of our investment in Best Buy Europe, partially offset by $(6) million of expense related to a tax allocation between continuing and discontinued operations. The fiscal 2014 effective tax rate for discontinued operations differs from the statutory tax rate primarily due to the tax allocation, restructuring charges and the impairment of our investment in Best Buy Europe. The restructuring charges and impairment generally included minimal related tax benefit. The deferred tax assets related to the restructuring charges generally resulted in an increase in the valuation allowance in an equal amount, while the investment impairment is generally not tax deductible.
