Accounting Policies [Abstract]
Organization and Summary of Significant Accounting Policies	Basis of Presentation Western Digital Corporation (the “Company” or “Western Digital”) is a leading developer, manufacturer and provider of data storage devices and solutions that address the needs of the information technology industry and the infrastructure that enables the storage of data. The Company also generates license and royalty revenue related to its intellectual property. The accounting policies followed by the Company are set forth in Part II, Item 8, Note 1 of the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended July 1, 2016. In the opinion of management, all adjustments necessary to fairly state the unaudited condensed consolidated financial statements have been made. All such adjustments are of a normal, recurring nature. Certain information and footnote disclosures normally included in the consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended July 1, 2016. The results of operations for interim periods are not necessarily indicative of results to be expected for the full year. Fiscal Year The Company’s fiscal year ends on the Friday nearest to June 30 and typically consists of 52 weeks. Fiscal year 2017, which ends on June 30, 2017, and fiscal year 2016, which ended on July 1, 2016, are both comprised of 52 weeks, with all quarters presented consisting of 13 weeks. Reclassifications Certain prior year amounts have been reclassified in the condensed consolidated statement of cash flows to conform to the current year presentation. Use of Estimates Company management has made estimates and assumptions relating to the reporting of certain assets and liabilities in conformity with U.S. GAAP. These estimates and assumptions have been applied using methodologies that are consistent throughout the periods presented. However, actual results could differ materially from these estimates. Accounting Changes and Recent Accounting Pronouncements Recently Adopted In April 2015, the Financial Accounting Standard Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-05, “Intangibles — Goodwill and Other — Internal-Use Software (Subtopic 350-40)” (“ASU 2015-05”), which provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The Company’s adoption of ASU 2015-05 at the beginning of the current year did not have a material impact on its condensed consolidated financial statements. Recently Issued In October 2016, the FASB issued ASU No. 2016-16, “Intra-Entity Transfers of Assets Other Than Inventory” (“ASU 2016-16”). The new standard removes the prohibition in ASC 740 against the immediate recognition of the current and deferred income tax effects of intra-entity transfers of assets other than inventory. The ASU is intended to reduce the complexity of U.S. GAAP and diversity in practice related to the tax consequences of certain types of intra-entity asset transfers, particularly those involving intellectual property. The new standard is effective for fiscal years beginning after December 15, 2017, which for the Company is the first quarter of 2019. Early adoption is permitted. The Company is currently evaluating the impact ASU 2016-16 will have on its consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230)” (“ASU 2016-15”). The new standard addresses certain cash flows issues regarding the classification of certain cash receipts and cash payments, which among others, includes the Company’s disclosure requirement related to debt prepayment or extinguishment costs and distributions received from equity method investees. The new standard is effective for fiscal years beginning after December 15, 2017, which for the Company is the first quarter of 2019. Early adoption is permitted. The Company expects to adopt this standard in the first quarter of 2019. The Company is currently evaluating the impact ASU 2016-15 will have on its consolidated financial statements and related disclosures. In March 2016, the FASB issued ASU No. 2016-09, “Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”). The new standard simplifies several aspects of the accounting for share-based payment transactions and states that, among other things, all excess tax benefits and tax deficiencies should be recognized as income tax expense or benefit in the income statement and an entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. The new standard is effective for fiscal years beginning after December 15, 2016, and interim periods within those years, which for the Company is the first quarter of 2018. Early adoption is permitted. The Company expects to adopt this standard in the first quarter of 2018. The Company is currently evaluating the impact ASU 2016-09 will have on its consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The new standard, among other things, requires lessees to recognize a right-of-use asset and a lease liability for leases. The new standard is effective for fiscal years beginning after December 15, 2018, which for the Company is the first quarter of 2020. Early adoption is permitted. The Company expects to adopt this standard in the first quarter of 2020. The Company is currently evaluating the impact ASU 2016-02 will have on its consolidated financial statements and related disclosures. In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments — Overall: Recognition and Measurement of Financial Assets and Financial Liabilities” (“ASU 2016-01”), which provides guidance related to accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. In addition, the FASB clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. ASU 2016-01 is effective for fiscal years beginning after December 15, 2017, which for the Company is the first quarter of 2019. Early adoption is not permitted. The Company is currently evaluating the impact ASU 2016-01 will have on its consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers” (“ASU 2014-09”), which amends the guidance in former Accounting Standards Codification Topic 605, “Revenue Recognition,” to provide a single, comprehensive revenue recognition model for all contracts with customers. The new standard requires an entity to recognize revenue in a manner that depicts the transfer of promised goods or services to customers in amounts that reflect the consideration to which an entity expects to be entitled in exchange for those goods or services. The new standard also requires entities to enhance disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Company does not expect the proposed standard to materially change the timing of revenue recognition for product revenue; however, the proposed standard may accelerate the timing of revenue recognition for the Company’s license and royalty contracts. In August 2015, the FASB issued ASU 2015-14, which deferred the effective date of ASU 2015-14 by one year. The new standard allows for either a full retrospective or a modified retrospective transition method. Early application is permitted only as of annual reporting periods beginning after December 15, 2016, which for the Company is the first quarter of 2018. The Company has not yet selected a transition method and currently expects to adopt this standard in the first quarter of 2019.

⁽¹⁾	Euro Term Loan B and Euro Term Loan B-1 outstanding principal amounts as of September 30, 2016 and July 1, 2016 were based upon the Euro to U.S. dollar exchange rate as of those respective dates.

Term Loans

In the first quarter ended September 30, 2016, the Company settled in full the principal amounts of the $3.75 billion U.S. Term Loan B and the €885 million Euro Term Loan B, plus accrued interest. In connection with the settlement of the U.S. Term Loan B and Euro Term Loan B, the Company recognized a loss on debt extinguishment of $227 million consisting of unamortized issuance costs and debt discount fees.

On August 17, 2016, the Company borrowed $3.0 billion under a new U.S. dollar-denominated term loan (“U.S. Term Loan B-1”) under the Credit Agreement (as defined below) and used the proceeds of this new loan and cash of $750 million to prepay in full the U.S. Term Loan B previously outstanding under the Credit Agreement. The U.S. Term Loan B-1 has an interest rate equal to, at the Company’s option, either an adjusted LIBOR rate, subject to a 0.75% floor, plus 3.75% or a base rate plus 2.75% (4.50% at September 30, 2016). Principal payments on U.S. Term Loan B-1 of 0.25% are due quarterly and began on September 30, 2016 with the balance due on April 29, 2023. The U.S. Term Loan B-1 issuance costs of $5 million are amortized to interest expense over the term of the loan. As of September 30, 2016, issuance costs of $5 million remain unamortized.

On September 22, 2016, the Company borrowed €885 million under a new Euro-denominated term loan (“Euro Term Loan B-1”) under the Credit Agreement and used the proceeds of this new loan to prepay in full the Euro Term Loan B previously outstanding under the Credit Agreement. The Euro Term Loan B-1 has an interest rate equal to an adjusted EURIBOR rate, subject to a 0.75% floor, plus 3.25% (4.00% at September 30, 2016). Principal payments on Euro Term Loan B-1 of 0.25% are due quarterly and began on September 30, 2016 with the balance due on April 29, 2023. The Euro Term Loan B-1 issuance costs of $2 million are amortized to interest expense over the term of the loan. As of September 30, 2016, issuance costs of $2 million remain unamortized.

Credit Agreement

On April 29, 2016, the Company entered into a new credit agreement (the “Credit Agreement”) that provided for a $4.125 billion Term Loan A, a $3.750 billion U.S. Term Loan B, a €885 million Euro Term Loan B and a $1.0 billion revolving credit facility. As described above, during the first quarter ended September 30, 2016, the U.S. Term Loan B and Euro Term Loan B were settled and replaced with the $3.0 billion U.S. Term Loan B-1 and the €885 million Euro Term Loan B-1, respectively.

The revolving credit facility includes a $200 million sublimit for letters of credit. As of September 30, 2016, the revolving credit facility was not drawn upon, and there was no outstanding balance. Beginning in September 2017, we are required to make quarterly principal payments on Term Loan A totaling $206 million in 2018, $309 million in 2019, $413 million in 2020 and the remaining balance of $3.197 billion due in 2021. As of September 30, 2016, Term Loan A had an outstanding balance of $4.125 billion with a variable interest rate of 2.526%.

The obligations under the Credit Agreement are guaranteed by HGST, Inc., WD Media, LLC, Western Digital (Fremont), LLC and Western Digital Technologies, Inc. (“WDT”) (together referred to as the “WD Guarantors”), and are secured on a first-priority basis by a lien on substantially all the assets and properties of the Company and the WD Guarantors, including all of the capital stock held by these entities (subject to a 65% limitation on pledges of capital stock of foreign subsidiaries and domestic holding companies of foreign subsidiaries), subject to certain exceptions.

The term loans and the revolving credit loans under the Credit Agreement may be prepaid in whole or in part at any time without premium or penalty, subject to certain conditions, except that the U.S. Term Loan B-1 and the Euro Term Loan B-1 require us to pay a 1.0% prepayment fee if the loans thereunder are repaid in connection with certain “repricing” transactions on or before February 17, 2017, with respect to U.S. Term Loan B-1, and March 22, 2017, with respect to Euro Term Loan B-1.

Covenants

The Credit Agreement requires the Company to comply with certain financial covenants, such as a leverage ratio and an interest coverage ratio. In addition, the documents governing substantially all of our outstanding debt, including the Credit Agreement, require the Company to comply with customary covenants that limit or restrict the Company’s and its subsidiaries’ ability to incur liens and indebtedness; make certain restricted payments, acquisitions, investments, loans and guarantees; and enter into certain transactions with affiliates, mergers and consolidations.

Additional Bridge Facility

On May 12, 2016, WDT entered into a short-term senior secured bridge credit agreement providing for $3.0 billion in aggregate principal amount of senior secured bridge loans. On July 21, 2016, the Company repaid in full the $3.0 billion aggregate principal amount outstanding, together with accrued interest.

Senior Notes

On April 13, 2016, the Company completed an offering of its $1.875 billion aggregate principal amount of 7.375% senior secured notes due 2023 (the “Secured Notes”) and $3.350 billion aggregate principal amount of 10.500% senior unsecured notes due 2024 (the “Unsecured Notes” and, together with the Secured Notes, the “Notes”). The Company is not required to make principal payments on the Notes prior to their respective maturity dates, except that the Company may be required to offer to purchase the Notes upon the occurrence of a change of control (as defined in the indentures governing the Notes) or with the proceeds of certain non-ordinary course asset sales. Interest payments on the Notes are due semi-annually in arrears.

The Notes are guaranteed by the WD Guarantors, and the Secured Notes and related guarantees are secured on an equal and ratable basis by liens on the same assets that secure indebtedness under the Credit Agreement.

Convertible Notes, Exchange Options and Call Options

As of July 1, 2016, the Company had outstanding, through the acquisition of SanDisk, $129 million aggregate principal amount of its 1.5% Convertible Senior Notes due 2017 (the “2017 Notes”) and $310 million aggregate principal amount of its 0.5% Convertible Senior Notes due 2020 (the “2020 Notes” and, together with the 2017 Notes, the “Convertible Notes”). The 2017 Notes mature on August 15, 2017 and the 2020 Notes mature on November 15, 2020.

During the three months ended September 30, 2016, the Company paid to the holders of the Convertible Notes for conversion and repurchase, $490 million of cash and 0.3 million shares of the Company’s common stock with an aggregate value of $16 million.

As of September 30, 2016, $37 million principal amount of the 2020 Notes and less than $1 million principal amount of the 2017 Notes were outstanding. For the 2020 Notes that remain outstanding, the conversion rate is 10.9006 units of reference property per $1,000 principal amount of the 2020 Notes, corresponding to 2.6020 shares of the Company’s common stock and $735.79 of cash, subject to adjustments under the indenture. The 2020 Notes are not currently exchangeable into reference property.

The Convertible Notes were bifurcated into a debt host and exchange option for accounting purposes. The exchange options are accounted for as a derivative liability because they are predominantly settled in cash. Changes in the fair value of the exchange options are reported in Other income (expense), net in the condensed consolidated statements of operations until the Company extinguishes the related debt. The exchange options are measured and reported at fair value on a recurring basis, within Level 3 of the fair value hierarchy. The fair value of the unredeemed and unsettled exchange options was reported in accrued expenses and other liabilities in the condensed consolidated balance sheets. See Note 10 to the condensed consolidated financial statements for additional disclosures related to the fair values of the exchange options. For the three months ended September 30, 2016, the change in the fair value of the outstanding exchange options related to the Convertible Notes resulted in an immaterial gain.

In connection with the SanDisk acquisition, the Company assumed the outstanding call options entered into by SanDisk at the inception of the respective Convertible Notes, which were structured to reduce the potential economic dilution associated with the conversion of Convertible Notes. The call options are derivative instruments classified as an asset that result in the Company receiving cash and shares that partially offset the Company’s obligation upon conversion of the Convertible Notes. The fair value of the unredeemed and unsettled call options was reported in other current assets and other non-current assets in the condensed consolidated balance sheets. During the three months ended September 30, 2016, under the call options, the Company received $61 million of cash and 0.1 million shares of the Company’s common stock which had an aggregate value of $11 million. During the three months ended September 30, 2016, the Company recognized an immaterial non-cash loss related to the change in value in the outstanding call options. The value of the call options at September 30, 2016 was immaterial.

The exchange and repurchase of the Convertible Notes and related settlement of the call options during the three months ended September 30, 2016 resulted in a net loss of $5 million.

Commitments, Contingencies and Related Parties

Flash Ventures

The Company’s business ventures with Toshiba Corporation (“Toshiba”) consist of three separate legal entities: Flash Partners Ltd. (“Flash Partners”), Flash Alliance Ltd. (“Flash Alliance”) and Flash Forward Ltd (“Flash Forward” and together with Flash Partners and Flash Alliance, “Flash Ventures”). The Company has a 49.9% ownership interest and Toshiba has a 50.1% ownership interest in each of these entities. Through these ventures, the Company and Toshiba collaborate in the development and manufacture of NAND flash memory products, which are manufactured by Toshiba at its wafer fabrication facilities located in Yokkaichi, Japan, using semiconductor manufacturing equipment individually owned or leased by each Flash Ventures entity. The entities within Flash Ventures purchase wafers from Toshiba at cost and then resell those wafers to the Company and Toshiba at cost plus a markup.

The Company accounts for its ownership position of each entity with Flash Ventures under the equity method of accounting. The financial and other support provided by the Company in all periods presented was either contractually required or the result of a joint decision to expand wafer capacity, transition to new technologies or refinance existing equipment lease commitments. Entities within Flash Ventures are variable interest entities (“VIEs”). The Company evaluated whether it is the primary beneficiary of any of the entities within Flash Ventures for all periods presented and determined that it is not the primary beneficiary of any of the entities within Flash Ventures because it does not have a controlling financial interest in any of those entities. In determining whether the Company is the primary beneficiary, the Company analyzed the primary purpose and design of Flash Ventures, the activities that most significantly impact Flash Ventures’ economic performance, and whether the Company had the power to direct those activities. The Company concluded, based upon its 49.9% ownership, the voting structure and the manner in which the day-to-day operations are conducted for each entity within Flash Ventures, that the Company lacked the power to direct most of the activities that most significantly impact the economic performance of each entity within Flash Ventures.

During the three months ended September 30, 2016, the Company purchased NAND flash memory wafers from Flash Ventures and made loans to, and investments in, Flash Ventures totaling $127 million and $20 million, respectively, and received loan repayments from Flash Ventures of $120 million. At September 30, 2016 and July 1, 2016, the Company had accounts payable balances due to Flash Ventures of $190 million and $168 million, respectively.

The Company’s maximum reasonably estimable loss exposure (excluding lost profits) as a result of its involvement with Flash Ventures, based upon the Japanese yen to U.S. dollar exchange rate at September 30, 2016, is presented below. Flash Ventures’ investments are denominated in Japanese yen and the maximum possible loss exposure excludes any cumulative translation adjustment due to revaluation from the Japanese yen to the U.S. dollar.



	September 30, 2016		July 1, 2016
	(in millions)
Notes receivable	$	580	$	563
Equity investments	637		608
Operating lease guarantees	1,235		1,151
Prepayments	30		34
Maximum estimable loss exposure	$	2,482	$	2,356

The Company is committed to purchase its provided three-month forecast of Flash Ventures’ NAND wafer supply, which generally equals 50% of Flash Ventures’ output. The Company is not able to estimate its total wafer purchase commitment obligation beyond its rolling three-month purchase commitment because the price is determined by reference to the future cost of producing the semiconductor wafers. In addition, the Company is committed to fund 49.9% to 50.0% of each Flash Ventures entity’s investments to the extent that each Flash Ventures entity’s operating cash flow is insufficient to fund these investments.

The following table presents, as of September 30, 2016, the notes receivable from and equity investments in Flash Ventures:



	September 30, 2016		July 1, 2016

Investment in Flash Alliance	310		306
Investment in Flash Forward	122		100
Total notes receivable and investments in Flash Ventures	$	1,217	$	1,171

The Company makes, or will make, loans to Flash Ventures to fund equipment investments for new process technologies and additional wafer capacity. The Company aggregates its Flash Ventures’ notes receivable into one class of financing receivables due to the similar ownership interest and common structure in each Flash Venture entity. For all reporting periods presented, no loans were past due and no loan impairments were recorded. The Company’s notes receivable from each Flash Ventures entity, denominated in Japanese yen, are secured by equipment owned by that Flash Ventures entity.

The Company assesses financing receivable credit quality through financial and operational reviews of the borrower and creditworthiness, including credit rating agency ratings, of significant investors of the borrower, where material or known. Impairments, when required for credit worthiness, are recorded in Other income (expense), net in the condensed consolidated statements of operations.

Off-Balance Sheet Liabilities

Flash Ventures sells and leases back from a consortium of financial institutions a portion of its tools and has entered into equipment lease agreements of which the Company guarantees half of the total outstanding obligations. The lease agreements contain customary covenants for Japanese lease facilities. In addition to containing customary events of default related to Flash Ventures that could result in an acceleration of Flash Ventures’ obligations, the lease agreements contain acceleration clauses for certain events of default related to the guarantors, including the Company.

The following table presents the Company’s portion of the remaining guarantee obligations under the Flash Ventures’ lease facilities in both Japanese yen and U.S. dollar-equivalent based upon the Japanese yen to U.S. dollar exchange rate at September 30, 2016.

The Company and Toshiba have agreed to mutually contribute to, and indemnify each other and Flash Ventures for, environmental remediation costs or liability resulting from Flash Ventures’ manufacturing operations in certain circumstances. The Company has not made any indemnification payments, nor recorded any indemnification receivables, under any such agreements. As of September 30, 2016, no amounts have been accrued in the consolidated financial statements with respect to these indemnification guarantees.

Legal Proceedings	Legal Proceedings Unless otherwise stated below, for each of the matters described below, the Company has either recorded an accrual for losses that are probable and reasonably estimable or has determined that, while a loss is reasonably possible (including potential losses in excess of the amounts accrued by the Company), a reasonable estimate of the amount of loss or range of possible losses with respect to the claim or in excess of amounts already accrued by the Company cannot be made. The ability to predict the ultimate outcome of such matters involves judgments, estimates and inherent uncertainties. The actual outcome of such matters could differ materially from management’s estimates. Solely for purposes of this note, “WD” refers to Western Digital Corporation or one or more of its subsidiaries excluding HGST prior to the closing of the Company’s acquisition of HGST on March 8, 2012 (the “HGST Closing Date”) and SanDisk prior to May 12, 2016 (the “SanDisk Closing Date”). HGST refers to Hitachi Global Storage Technologies Holdings Pte. Ltd. or one or more of its subsidiaries as of the HGST Closing Date, and SanDisk refers to SanDisk Corporation or one or more of its subsidiaries as of the SanDisk Closing Date and “the Company” refers to Western Digital Corporation and all of its subsidiaries on a consolidated basis including HGST and SanDisk. Intellectual Property Litigation In June 2008, Convolve, Inc. (“Convolve”) filed a complaint in the Eastern District of Texas against WD, HGST, and two other companies alleging infringement of U.S. Patent Nos. 6,314,473 and 4,916,635. The complaint sought unspecified monetary damages and injunctive relief. In October 2008, Convolve amended its complaint to allege infringement of only the ’473 patent. The ’473 patent allegedly relates to interface technology to select between certain modes of a disk drive’s operations relating to speed and noise. In July 2011, a verdict was rendered against WD and HGST in an amount that is not material to the Company’s financial position, results of operations or cash flows, for which the Company previously recorded an accrual. In March 2015, WD and HGST filed Notices of Appeal with the United States District Court for the Federal Circuit (“Federal Circuit”). In April 2015, Convolve filed a motion for reconsideration of the final judgment, and in May 2015, the Federal Circuit deactivated the appeal pending the Court’s decision on reconsideration. WD and HGST intend to continue to defend themselves vigorously in this matter. In May 2016, Lambeth Magnetic Structures, LLC (“Lambeth”) filed a complaint in the Western District of Pennsylvania against WD and certain of its subsidiaries alleging infringement of U.S. Patent No. 7,128,988. The complaint seeks unspecified monetary damages and injunctive relief. The ’988 patent, entitled “Magnetic Material Structures, Devices and Methods,” allegedly relates to a magnetic material structure for hard disk drive devices. The Company intends to defend itself vigorously in this matter. Antitrust On June 25, 2010, Ritz Camera & Image, LLC (“Ritz”) filed a complaint captioned Ritz Camera & Image, LLC v. SanDisk Corporation, Inc. and Eliyahou Harari in the U.S. District Court for the Northern District of California, alleging that SanDisk violated federal antitrust laws by conspiring to monopolize and monopolizing the market for flash memory products. The lawsuit purports to be on behalf of direct purchasers of flash memory products sold by SanDisk and SanDisk-controlled joint ventures from June 25, 2006 through the present. The complaint alleged that SanDisk created and maintained a monopoly by fraudulently obtaining patents and using them to restrain competition and by allegedly converting other patents for its competitive use. The complaint sought damages, injunctive relief, and fees and costs. On February 24, 2011, the District Court granted in part SanDisk’s motion to dismiss, which resulted in Dr. Harari being dismissed as a defendant. Between 2013 and 2014, the District Court granted Ritz’s motion to substitute in as named plaintiff Albert Giuliano, the Chapter 7 Trustee of the Ritz bankruptcy estate, and the Trustee’s motions to add as named plaintiffs CPM Electronics Inc., E.S.E. Electronics, Inc. and Mflash, Inc. On May 14, 2015, the District Court granted in part plaintiffs’ motion for class certification. On April 29, 2016, the court granted SanDisk’s motion for summary judgment and entered judgment in SanDisk's favor as to all of the plaintiffs’ claims. On May 31, 2016, the plaintiffs filed a notice of appeal to the U.S. Court of Appeals for the Federal Circuit. The appeal is currently pending. On July 15, 2010, Samsung Electronics Co., Ltd. (“Samsung”) filed an action against Panasonic and SD-3C LLC (“SD-3C”) in the U.S. District Court for the Northern District of California, alleging that defendants violated federal antitrust laws and California antitrust and unfair competition laws relating to the licensing practices and operations of SD-3C. The complaint seeks damages, restitution, injunctive and declaratory relief, and fees and costs. SanDisk is not a defendant in this case, but it established SD-3C along with Panasonic and Toshiba, and the complaint includes various factual allegations concerning SanDisk. As a member of SD-3C, SanDisk could be responsible for a portion of any monetary award. Other requested relief, if granted, could result in a loss of revenue to SanDisk. On August 25, 2011, the District Court granted the defendants’ motion to dismiss, dismissing Samsung’s patent misuse claim with prejudice and all other claims with leave to amend. Samsung filed an amended complaint on September 16, 2011. On January 3, 2012, the District Court granted the defendants’ motion to dismiss Samsung’s amended complaint without leave to amend. Samsung appealed. On April 4, 2014, the U.S. Court of Appeals for the Ninth Circuit reversed the District Court’s dismissal and remanded the case to the District Court for further proceedings. Samsung filed a third amended complaint on January 20, 2015. On September 30, 2015, the District Court granted in part the defendants’ motion to dismiss with leave to amend. On October 21, 2015, Samsung filed a fourth amended complaint. On November 4, 2015, the defendants filed a motion to dismiss. On September 26, 2016, the District Court stayed the litigation pending the outcome of an ongoing arbitration between Samsung and Toshiba. The District Court denied the motion to dismiss without prejudice to refiling after the stay is lifted. On March 15, 2011, a complaint was filed against SanDisk, SD-3C, Panasonic Corporation, Panasonic Corporation of North America, Toshiba and Toshiba America Electronic Components, Inc. in the U.S. District Court for the Northern District of California. The lawsuit purports to be on behalf of a nationwide class of indirect purchasers of Secure Digital (“SD”) cards. The complaint asserts claims under federal antitrust laws and California antitrust and unfair competition laws, as well as common law claims. The complaint seeks damages, restitution, injunctive relief, and fees and costs. The plaintiffs allege that the defendants conspired to artificially inflate the royalty costs associated with manufacturing SD™ cards, which in turn allegedly caused the plaintiffs to pay higher prices for SD cards. The allegations are similar to and incorporate allegations in Samsung Electronics Co., Ltd. v. Panasonic Corp., et al., described above. On May 21, 2012, the District Court granted the defendants’ motion to dismiss the complaint with prejudice. The plaintiffs appealed. On May 14, 2014, the U.S. Court of Appeals for the Ninth Circuit reversed the District Court’s dismissal and remanded the case to the District Court for further proceedings. On February 3, 2015, the plaintiffs filed a second amended complaint in the District Court. On September 30, 2015, the District Court granted the defendants’ motion to dismiss with leave to amend. On November 4, 2015, the plaintiffs filed a third amended complaint. On November 25, 2015, the defendants filed a motion to dismiss the plaintiffs’ federal law claims. On October 3, 2016, the District Court granted the defendants’ motion with leave to amend. On October 21, 2016, the defendants filed a motion to dismiss the plaintiffs’ remaining claims. Discovery is presently stayed until after completion of the pleading stage. The Company intends to defend itself vigorously in this matter. Securities Beginning on March 30, 2015, SanDisk and two officers, Sanjay Mehrotra and Judy Bruner, were named in three putative class action lawsuits filed in the United States District Court for the Northern District of California. Two complaints are allegedly brought on behalf of a class of purchasers of SanDisk’s securities between October 16, 2014 and March 25, 2015, and one is brought on behalf of a purported class of purchasers of SanDisk’s securities between April 16, 2014 and April 15, 2015. The complaints generally allege violations of federal securities laws arising out of alleged misstatements or omissions by the defendants during the alleged class periods. The complaints seek, among other things, damages and fees and costs. On July 9, 2015, the Court consolidated the cases and appointed Union Asset Management Holding AG and KBC Asset Management NV as lead plaintiffs. The lead plaintiffs filed an amended complaint in August 2015. On January 22, 2016, the court granted the defendants’ motion to dismiss and dismissed the amended complaint with leave to amend. On February 22, 2016, the court issued an order appointing as new lead plaintiffs Bristol Pension Fund; City of Milford, Connecticut Pension & Retirement Board; Pavers and Road Builders Pension, Annuity and Welfare Funds; the Newport News Employees’ Retirement Fund; and Massachusetts Laborers’ Pension Fund (collectively, the “Institutional Investor Group”). On March 23, 2016, the Institutional Investor Group filed an amended complaint. The defendants filed a motion to dismiss on April 29, 2016. On June 24, 2016, the court granted the motion and dismissed the amended complaint with leave to amend. On July 15, 2016, the Institutional Investor Group filed a further amended complaint. The Company filed a motion to dismiss on August 19, 2016. The Company intends to defend itself vigorously in this matter. Other Matters In December 2011, the German Central Organization for Private Copying Rights (Zentralstelle für private Überspielungsrechte) (“ZPÜ”), an organization consisting of several copyright collecting societies, instituted arbitration proceedings against WD’s German subsidiary (“WD Germany”) before the Copyright Arbitration Board (“CAB”) claiming copyright levies for multimedia hard drives, external hard drives and network hard drives sold or introduced into commerce in Germany by WD Germany from January 2008 through December 2010. In February 2013, WD Germany filed a declaratory relief action against ZPÜ in the Higher Regional Court of Munich (the “Higher Court”), seeking an order from the court to determine the copyright levy issue. On May 21, 2013, ZPÜ filed a counter-claim against WD Germany with the Higher Court, seeking copyright levies for multimedia hard drives, external hard drives and network hard drives sold or introduced into commerce from January 2008 through December 2010 based on tariffs published by ZPÜ on November 3, 2011. In January 2015, the Higher Court ruled in favor of ZPÜ. In its ruling, the Higher Court declared that WD Germany must pay certain levies on certain products which it sold in Germany between January 2008 and December 2010. The judgment specifies levy amounts on certain products sold from January 2008 through December 2010 and directs WD Germany to provide applicable sales data to ZPÜ. The exact amount of the judgment has not been determined. ZPÜ and WD Germany filed appeals with the German Federal Court of Justice in February 2015. The Company intends to defend itself vigorously in this matter. In December 2014, ZPÜ submitted a pleading to the CAB seeking copyright levies for multimedia hard drives, external hard drives and network hard drives sold or introduced into commerce in Germany by WD Germany between January 2012 and December 2013. The Company intends to defend itself vigorously in this matter. The Company has recorded an accrual for German copyright levies in an amount that is not material to the Company’s financial position, results of operations or cash flows. It is reasonably possible that the Company may incur losses totaling up to $133 million, including the amounts accrued. In the normal course of business, the Company is subject to other legal proceedings, lawsuits and other claims. Although the ultimate aggregate amount of probable monetary liability or financial impact with respect to these other matters is subject to many uncertainties, management believes that any monetary liability or financial impact to the Company from these other matters, individually and in the aggregate, would not be material to the Company’s financial condition, results of operations or cash flows. However, any monetary liability and financial impact to the Company from these other matters could differ materially from the Company’s expectations.

Income tax expense of $95 million for the three months ended September 30, 2016 is attributable to discrete effects consisting of income tax expense from the integration of SanDisk of $90 million and a valuation allowance on acquired tax attributes of $109 million, partially offset by income tax benefit from deductible debt issuance costs, debt discounts and prepayment fees from the debt refinancing of $96 million and from decreases in the Company’s liability for unrecognized tax benefits due to lapses in the statute of limitations of $8 million. These discrete items are the primary drivers of the negative effective tax rate for the three months ended September 30, 2016.

The primary drivers for the difference between the effective tax rate for the three months ended September 30, 2016 and the U.S. Federal statutory rate of 35% are the discrete items described above, the current year generation of tax credits and tax holidays in Malaysia, the Philippines, Singapore and Thailand that expire at various dates from 2016 through 2029. For the three months ended October 2, 2015, the difference between the effective tax rate and the U.S. Federal statutory rate of 35% is primarily due to tax holidays in Malaysia, the Philippines, Singapore and Thailand that expire at various dates from 2016 through 2029.

In the three months ended September 30, 2016, the Company recorded a net decrease of $6 million in its liability for unrecognized tax benefits. As of September 30, 2016, the Company’s liability for unrecognized tax benefits was approximately $485 million. Accrued interest and penalties related to unrecognized tax benefits as of September 30, 2016 was $78 million.

The Internal Revenue Service (“IRS”) previously completed its field examination of the Company’s federal income tax returns for fiscal years 2006 through 2009 and proposed certain adjustments. The Company received Revenue Agent Reports from the IRS that seek to increase the Company’s U.S. taxable income which would result in additional federal tax expense totaling $795 million, subject to interest. The issues in dispute relate primarily to transfer pricing with the Company’s foreign subsidiaries and intercompany payable balances. The Company disagrees with the proposed adjustments and in September 2015, filed a protest with the IRS Appeals Office and received the IRS rebuttal in July 2016. The Company believes that its tax positions are properly supported and will vigorously contest the position taken by the IRS. In September 2015, the IRS commenced an examination of the Company’s fiscal years 2010 through 2012.

The Company believes that adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax examinations cannot be predicted with certainty. If any issues addressed in the Company’s tax examinations are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs. As of September 30, 2016, it is not possible to estimate the amount of change, if any, in the unrecognized tax benefits that is reasonably possible within the next twelve months. Any significant change in the amount of the Company’s liability for unrecognized tax benefits would most likely result from additional information or settlements relating to the examination of the Company’s tax returns.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Financial Instruments Carried at Fair Value

Financial assets and liabilities that are remeasured and reported at fair value at each reporting period are classified and disclosed in one of the following three levels:


Level 1.	Quoted prices in active markets for identical assets or liabilities.


Level 2.	Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.


Level 3.	Inputs that are unobservable for the asset or liability and that are significant to the fair value of the assets or liabilities.

The following tables present information about the Company’s financial assets and liabilities that are measured at fair value on a recurring basis as of September 30, 2016 and July 1, 2016, and indicate the fair value hierarchy of the valuation techniques utilized to determine such values:

Assets and Liabilities Measured at Fair Value on a Recurring Basis Using Significant Unobservable Inputs (Level 3)

The fair value measurement of the call options and exchange options arising from the assumed Convertible Notes which are not actively traded, is determined using unobservable inputs (Level 3). These inputs include (i) the estimated amount and timing of settlement of the underlying debt; (ii) the probability of the achievement of the factor(s) on which the settlement is based; (iii) the risk-adjusted discount rate based on the expected term to maturity of the debt; and (iv) economic incentive for holders to exercise their exchange options. Significant increases or decreases in any of those inputs in isolation could result in a significantly lower or higher fair value measurement.

There were no transfers of call options or exchange options out of Level 3 for three months ended September 30, 2016.

The following is a reconciliation of the call options reported in other current assets and other non-current assets in the Company’s condensed consolidated balance sheets as of September 30, 2016.

Derivatives

Sep. 30, 2016

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

The majority of the Company’s transactions are in U.S. dollars; however, some transactions are based in various foreign currencies. The Company purchases short-term, foreign exchange contracts to hedge the impact of foreign currency exchange fluctuations on certain underlying assets, liabilities and commitments for operating expenses and product costs denominated in foreign currencies. The purpose of entering into these hedging transactions is to minimize the impact of foreign currency fluctuations on the Company’s results of operations. These contract maturity dates do not exceed 12 months. All foreign exchange contracts are for risk management purposes only. The Company does not purchase foreign exchange contracts for speculative or trading purposes. As of September 30, 2016, the Company had outstanding foreign exchange contracts with commercial banks for British Pound Sterling, Euro, Japanese Yen, Malaysian Ringgit, Philippine Peso, Singapore Dollar and Thai Baht, which were designated as either cash flow or fair value hedges.

If the derivative is designated as a cash flow hedge, the effective portion of the change in fair value of the derivative is initially deferred in accumulated other comprehensive income (loss), net of tax. These amounts are subsequently recognized into earnings when the underlying cash flow being hedged is recognized into earnings. Recognized gains and losses on foreign exchange contracts entered into for manufacturing-related activities are reported in cost of revenue and presented within cash flow from operations. Hedge effectiveness is measured by comparing the hedging instrument’s cumulative change in fair value from inception to maturity to the underlying exposure’s terminal value. The Company determined the ineffectiveness associated with its cash flow hedges to be immaterial to the condensed consolidated financial statements for the three months ended September 30, 2016 and October 2, 2015.

A change in the fair value of fair value hedges is recognized in earnings in the period incurred and is reported as a component of cost of revenue or operating expenses, depending on the nature of the underlying hedged item. All fair value hedges were determined to be effective as of September 30, 2016 and July 1, 2016. The changes in fair value on these contracts were immaterial to the condensed consolidated financial statements during the three months ended September 30, 2016 and October 2, 2015.

As of September 30, 2016, the net amount of unrealized gains with respect to the Company’s foreign exchange contracts that is expected to be reclassified into earnings within the next 12 months was $70 million. In addition, as of September 30, 2016, the Company did not have any foreign exchange contracts with credit-risk-related contingent features.

See Note 10 to the condensed consolidated financial statements for additional disclosures related to the Company’s foreign exchange contracts.

Acquisition

Acquisitions

Fiscal 2016 Acquisition

In May 2016, we acquired SanDisk, a global leader in NAND flash storage solutions primarily to deepen the Company’s expertise in non-volatile memory and enable the Company to vertically integrate into NAND, securing long-term access to solid state technology at a lower cost.

Assets Acquired and Liabilities Assumed at Fair Value

During the period, the Company adjusted the assessment of fair value for certain acquired inventory and property and equipment and a portion of the deferred tax liability. Management is continuing to assess the values assigned to the remaining assets acquired and liabilities assumed and may make further adjustments during the measurement period (through May 11, 2017) as further information becomes available. Any changes in the fair values of the assets acquired and liabilities assumed during the measurement period may result in adjustments to goodwill.

Pro Forma Financial Information

The financial information in the table below summarizes the combined results of operations for the Company and SanDisk, on a pro forma basis, as though the combination had occurred as of the beginning of 2016. The pro forma financial information for the period presented includes the effects of adjustments related to amortization charges from acquired intangible assets, depreciation charges from acquired fixed assets, interest expenses from financing the acquisition, stock-based compensation expenses from the conversion of unvested equity awards and the elimination of certain expenses directly related to the transaction.
