WESTERN DIGITAL CORPORATION
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

Note 1.    Organization and Basis of Presentation

Western Digital Corporation (“Western Digital” or the “Company”) is a leading developer, manufacturer, and provider of data storage devices and solutions that address the evolving needs of the information technology (“IT”) industry and the infrastructure that enables the proliferation of data in virtually every other industry. The Company creates environments for data to thrive. The Company is driving the innovation needed to help customers capture, preserve, access and transform an ever-increasing diversity of data. Everywhere data lives, from advanced data centers to mobile sensors to personal devices, the Company’s industry-leading solutions deliver the possibilities of data.

The Company’s broad portfolio of technology and products address the following key end markets: Client Devices; Data Center Devices and Solutions; and Client Solutions. The Company also generates license and royalty revenue from its extensive intellectual property (“IP”), which is included in each of these three end market categories.

The accounting policies followed by the Company are set forth in Part II, Item 8, Note 1, Organization and Basis of Presentation, of the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10‑K for the fiscal year ended July 3, 2020. In the opinion of management, all adjustments necessary to fairly state the 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 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 3, 2020. 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. Approximately every five to six years, the Company reports a 53-week fiscal year to align the fiscal year with the foregoing policy. Fiscal year 2021, which ends on July 2, 2021, will be comprised of 52 weeks, with all quarters presented consisting of 13 weeks. Fiscal year 2020, which ended on July 3, 2020, was comprised of 53 weeks, with the first quarter consisting of 14 weeks and the remaining quarters consisting of 13 weeks each.

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 with consideration given to the potential impacts of the coronavirus disease 2019 (“COVID-19”) pandemic. However, actual results could differ materially from these estimates and be significantly affected by the severity and duration of the pandemic, the extent of actions to contain or treat COVID-19, including the effects of ongoing vaccination efforts, how quickly and to what extent normal economic and operating activity can resume, and the severity and duration of the global economic downturn that results from the pandemic.

Segment Information

The Company manufactures, markets, and sells data storage devices and solutions in the U.S. and in foreign countries through its sales personnel, dealers, distributors, retailers, and subsidiaries. Historically, the Company has managed and reported under a single operating segment. Late in the first quarter of fiscal 2021, the Chief Executive Officer, who is the Company’s Chief Operating Decision Maker (“CODM”), announced a decision to reorganize the Company’s business by forming 2 separate product business units: flash-based products and hard disk drives (“HDD”). The Company is in the process of transitioning to this new operating model and discrete information has not yet been established to align with the new business structure. Management expects to finalize its assessment of its operating segments when the transition is completed, which is expected to be by the end of fiscal 2021.

Note 2.    Recent Accounting Pronouncements

Accounting Pronouncements Recently Adopted

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updates (“ASU”) No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). ASU 2016-13 seeks to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments, including trade receivables, and other commitments to extend credit held by a reporting entity at each reporting date. The amendments require an entity to replace the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects current expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The amendments are effective for fiscal years (and interim periods within those fiscal years) beginning after December 15, 2019, which for the Company is the first quarter of fiscal 2021. The Company adopted this standard effective July 4, 2020 (the beginning of fiscal 2021) with no material impact on its Condensed Consolidated Financial Statements.

In November 2018, the FASB issued ASU No. 2018-18, “Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606” (“ASU 2018-18”). ASU 2018-18 clarifies that certain transactions between collaborative arrangement participants should be accounted for as revenue when the collaborative arrangement participant is a customer in the context of a unit of account and precludes recognizing as revenue consideration received from a collaborative arrangement participant if the participant is not a customer. This ASU requires retrospective adoption to the date the Company adopted Accounting Standards Codification (ASC) 606 by recognizing a cumulative-effect adjustment to the opening balance of retained earnings of the earliest annual period presented. The Company adopted this standard effective July 4, 2020 (the beginning of fiscal 2021) with no material impact on its Condensed Consolidated Financial Statements.

Recently Issued Accounting Pronouncements Not Yet Adopted

In December 2019, the FASB issued ASU No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”). ASU 2019-12 removes certain exceptions for recognizing deferred taxes for investments, performing intraperiod allocation and calculating income taxes in interim periods. The ASU also adds guidance to reduce complexity in certain areas, including recognizing deferred taxes for tax goodwill and allocating taxes to members of a consolidated group. This ASU is effective for fiscal years (and interim periods within those fiscal years) beginning after December 15, 2020, which for the Company is the first quarter of fiscal 2022. Early adoption is permitted. The Company does not expect this update to have a material impact on its Condensed Consolidated Financial Statements.

Note 3.    Revenues

Contract assets represent the Company’s rights to consideration where performance obligations are completed but the customer payments are not due until another performance obligation is satisfied. The Company did not have any contract assets as of either January 1, 2021 or July 3, 2020.

The Company incurs sales commissions and other direct incremental costs to obtain sales contracts. The Company has applied the practical expedient to recognize the direct incremental costs of obtaining contracts as an expense when incurred if the amortization period is expected to be one year or less or the amount is not material, with these costs charged to Selling, general and administrative expenses. Other direct incremental costs to obtain contracts that have an expected benefit of greater than one year are amortized over the period of expected cash flows from the related contracts, and the amortization expense is recorded as a reduction to revenue. Total capitalized contract costs as of January 1, 2021 and July 3, 2020 as well as the related amortization for the three and six months ended January 1, 2021 and January 3, 2020 were not material.

Contract liabilities relate to customers’ payments in advance of performance under the contract and primarily relate to remaining performance obligations under support and maintenance contracts. As of January 1, 2021 and July 3, 2020, contract liabilities were not material.

The Company applies the practical expedients and does not disclose transaction price allocated to the remaining performance obligations for (i) arrangements that have an original expected duration of one year or less, which mainly consist of support and maintenance contracts, and (ii) variable consideration amounts for sale-based or usage-based royalties for IP license arrangements, which typically range longer than one year. Remaining performance obligations are mainly attributed to right-to-access patent license arrangements and customer support and service contracts, which will be recognized over the remaining contract period. The transaction price allocated to the remaining performance obligations as of January 1, 2021 was $91 million, which is mainly attributable to the functional IP license and service arrangements. The Company expects to recognize this amount as revenue as follows: $20 million during the remainder of fiscal 2021, $40 million in fiscal 2022, and $31 million in fiscal 2023 and thereafter.

Note 5.    Fair Value Measurements and Investments

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 January 1, 2021 and July 3, 2020, and indicate the fair value hierarchy of the valuation techniques utilized to determine such values:

Financial Instruments Not Carried at Fair Value

The carrying value of the Company’s revolving credit facility approximates its fair value given the revolving nature of the balance and the variable market interest rate. For financial instruments where the carrying value (which includes principal adjusted for any unamortized issuance costs, and discounts or premiums) differs from fair value (which is based on quoted market prices), the following table represents the related carrying value and fair value for each of the Company’s outstanding financial instruments. Each of the financial instruments presented below was categorized as Level 2 for all periods presented, based on the frequency of trading immediately prior to the end of the second quarter of 2021 and the fourth quarter of 2020, respectively.

Note 6.    Derivative Instruments and Hedging Activities

As of January 1, 2021, the Company had outstanding foreign exchange forward contracts that were designated as either cash flow hedges or non-designated hedges. Substantially all of the contract maturity dates of these foreign exchange forward contracts do not exceed 12 months. In addition, the Company had outstanding pay-fixed interest rate swaps that were designated as cash flow hedges of variable rate interest payments on a portion of its term loans through February 2023.

As of January 1, 2021, the amount of existing net losses related to cash flow hedges recorded in AOCI included $57 million related to the Company’s interest rate swaps that is expected to be reclassified to earnings after twelve months. In addition, as of January 1, 2021, the Company did not have any foreign exchange forward contracts with credit-risk-related contingent features.

Changes in fair values of the non-designated foreign exchange contracts are recognized in Other income, net and are largely offset by corresponding changes in the fair values of the foreign currency denominated monetary assets and liabilities. For each of the three and six months ended January 1, 2021 and January 3, 2020, total net realized and unrealized transaction and foreign exchange contract currency gains and losses were not material to the Company’s Condensed Consolidated Financial Statements.

Netting Arrangements

Under certain provisions and conditions within agreements with counterparties to the Company’s foreign exchange forward contracts, subject to applicable requirements, the Company has the right of offset associated with the Company’s foreign exchange forward contracts and is allowed to net settle transactions of the same currency with a single net amount payable by one party to the other. As of January 1, 2021 and July 3, 2020, the effect of rights of offset was not material and the Company did not offset or net the fair value amounts of derivative instruments in its Condensed Consolidated Balance Sheets.

Flash Ventures

The Company’s business ventures with Kioxia Corporation (“Kioxia”) consist of three separate legal entities: Flash Partners Ltd. (“Flash Partners”), Flash Alliance Ltd. (“Flash Alliance”), and Flash Forward Ltd. (“Flash Forward”), collectively referred to as “Flash Ventures”.

The following table presents the notes receivable from, and equity investments in, Flash Ventures as of January 1, 2021 and July 3, 2020:

Total notes receivable and investments in Flash Ventures$1,858 $1,875 

During the three and six months ended January 1, 2021 and during the three and six months ended January 3, 2020, the Company made net payments to Flash Ventures of $1.21 billion and $2.19 billion, and $648 million and $1.33 billion, respectively, for purchased flash-based memory wafers and net loans and investments.

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.

As of January 1, 2021 and July 3, 2020, the Company had Accounts payable balances due to Flash Ventures of $393 million and $407 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 January 1, 2021, is presented below. Investments in Flash Ventures are denominated in Japanese yen, and the maximum estimable loss exposure excludes any cumulative translation adjustment due to revaluation from the Japanese yen to the U.S. dollar.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The Company is obligated to pay for variable costs incurred in producing its share of Flash Ventures’ flash-based memory wafer supply, based on its three-month forecast, which generally equals 50% of Flash Ventures’ output. In addition, the Company is obligated to pay for half of Flash Ventures’ fixed costs regardless of the output the Company chooses to purchase. 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 capital investments to the extent that each Flash Ventures entity’s operating cash flow is insufficient to fund these investments.

In June 2019, an unexpected power outage incident occurred at the flash-based memory manufacturing facilities operated in Yokkaichi, Japan. The power outage incident impacted the facilities and process tools and resulted in damage to flash wafers in production and a reduction in the Company’s flash wafer availability. As a result of this incident, the Company incurred charges of $68 million for the six months ended January 3, 2020, which were recorded in Cost of revenue and primarily consisted of unabsorbed manufacturing overhead costs. During the six months ended January 1, 2021, the Company recovered $75 million related to this incident from its insurance carriers, which was recorded in Cost of revenue.

In May 2019, the Company entered into additional agreements with Kioxia to extend Flash Ventures to a new wafer fabrication facility, known as “K1,” located in Kitakami, Japan. The primary purpose of K1 is to provide clean room space to continue the transition of existing flash-based wafer capacity to newer technology nodes. K1 is now fully operational. In connection with the start-up of this facility, the Company agreed to prepay an aggregate of approximately $360 million over a 3-year period beginning in the first half of fiscal year 2020 toward K1 building depreciation, to be credited against future wafer charges. As of January 1, 2021, remaining committed prepayments totaled $149 million.

Inventory Purchase Commitments with Flash Ventures. Purchase orders placed under Flash Ventures for up to three months are binding and cannot be canceled.

Research and Development Activities. The Company participates in common research and development (“R&D”) activities with Kioxia and is contractually committed to a minimum funding level. R&D commitments are immaterial to the Condensed Consolidated Financial Statements.

Off-Balance Sheet Liabilities

Flash Ventures sells to 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 or all of the outstanding obligations under each lease agreement. The lease agreements are subject to customary covenants and cancellation events related to Flash Ventures and each of the guarantors. The occurrence of a cancellation event could result in an acceleration of Flash Ventures’ obligations and a call on the Company’s guarantees.

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 as of January 1, 2021.

The Company has not made any indemnification payments, nor recorded any indemnification receivables, under any such agreements. As of January 1, 2021, no amounts have been accrued in the Condensed Consolidated Financial Statements with respect to these indemnification agreements.

Unis Venture

The Company has a joint venture with Unisplendour Corporation Limited and Unissoft (Wuxi) Group Co. Ltd. (“Unis”), referred to as the “Unis Venture”, to market and sell the Company’s products in China and to develop data storage systems for the Chinese market in the future. The Unis Venture is 49% owned by the Company and 51% owned by Unis. The Company accounts for its investment in the Unis Venture under the equity method of accounting. Revenue on products distributed by the Unis Venture is recognized upon sell through to third-party customers. For both the three and six months ended January 1, 2021, the Company recognized approximately 3% of its consolidated revenue on products distributed by the Unis Venture. For both the three and six months ended January 3, 2020, the Company recognized approximately 1% of its consolidated revenue on products distributed by the Unis Venture.

The Company leases certain domestic and international facilities and data center space under long-term, non-cancelable operating leases that expire at various dates through 2034. These leases include no material variable or contingent lease payments. Operating lease assets and liabilities are recognized based on the present value of the remaining lease payments discounted using the Company’s incremental borrowing rate. Operating lease assets also include prepaid lease payments minus any lease incentives. Extension or termination options present in the Company’s lease agreements are included in determining the right-of-use asset and lease liability when it is reasonably certain the Company will exercise those options.

The remaining amount available to be repurchased under the Company’s current stock repurchase program as of January 1, 2021 was $4.5 billion. Repurchases under the stock repurchase program may be made in the open market or in privately negotiated transactions and may be made under a Rule 10b5-1 plan. The Company expects stock repurchases to be funded principally by operating cash flows.

Dividends to Shareholders

The Company issued a quarterly cash dividend from the first quarter of fiscal 2013 up to the third quarter of fiscal 2020. In April 2020, the Company suspended its dividend to reinvest in the business and to support its ongoing deleveraging efforts.

Note 12.    Income Tax Expense

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted in response to the COVID-19 pandemic in the U.S. The CARES Act, among other things, allows net operating losses arising in tax years 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes and increases the business interest expense limitation from 30% to 50% of adjusted taxable income for tax years 2019 and 2020. Additionally, countries around the world continue to implement emergency tax measures to provide relief similar to the CARES Act. The Company at present does not expect that any of the provisions of the CARES Act or the emergency tax measures around the world would result in a material cash benefit.

On December 27, 2020, the Consolidated Appropriations Act (the “Appropriations Act”) was enacted to fund the federal government through their fiscal year, extend certain expiring tax provisions and provide additional emergency relief to individuals and businesses related to the COVID-19 pandemic in the U.S. The Company at present does not expect any of the provisions of the Appropriations Act to have a material impact on its financial statements. The Company continues to monitor and evaluate the regulatory and interpretive guidance related to the CARES Act and the Appropriations Act, as well as legislation in other jurisdictions.

The Tax Cuts and Jobs Act (the “2017 Act”), enacted on December 22, 2017, includes a broad range of tax reform proposals affecting businesses. The Company completed its accounting for the tax effects of the enactment of the 2017 Act during the second quarter of fiscal 2019. However, the U.S. Treasury and the Internal Revenue Service (“IRS”) have issued tax guidance on certain provisions of the 2017 Act since the enactment date, and the Company anticipates the issuance of additional regulatory and interpretive guidance. The Company applied a reasonable interpretation of the 2017 Act along with the then-available guidance in finalizing its accounting for the tax effects of the 2017 Act. Any additional regulatory or interpretive guidance would constitute new information, which may require further refinements to the Company’s estimates in future periods.

The following table presents the Company’s Income tax expense and the effective tax rate:

The primary drivers of the difference between the effective tax rate for the three and six months ended January 1, 2021 and the U.S. Federal statutory rate of 21% are the relative mix of earnings and losses by jurisdiction, the deduction for foreign derived intangible income, credits, and tax holidays in Malaysia, the Philippines and Thailand that will expire at various dates during fiscal years 2021 through 2030. In addition, the effective tax rate for the three and six months ended January 1, 2021 includes the discrete effects of favorable adjustments proposed by tax authorities of $8 million. The effective tax rate for the six months ended January 1, 2021 also includes the discrete effects of net tax deficiencies from shortfalls of $12 million related to the vesting of stock-based awards and additional tax expense of $10 million from the re-measurement of deferred tax liabilities due to restructuring activities, which have no impact on the amount of income taxes paid by the Company.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The IRS previously completed its field examination of the Company’s federal income tax returns for fiscal years 2008 through 2012 and proposed certain adjustments. As previously disclosed, the Company received Revenue Agent Reports from the IRS for fiscal years 2008 through 2009, proposing adjustments relating 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 and the IRS Appeals Office did not reach a settlement on the disputed matters. On June 28, 2018, the IRS issued a statutory notice of deficiency with respect to the disputed matters for fiscal years 2008 through 2009, seeking to increase the Company’s U.S. taxable income by an amount that would result in additional federal tax through fiscal year 2009 totaling approximately $516 million, subject to interest and penalties. The Company filed a petition with the U.S. Tax Court in September 2018. On December 10, 2018, the IRS issued a statutory notice of deficiency with respect to fiscal years 2010 through 2012, seeking to increase the Company’s U.S. taxable income by an amount that would result in additional federal tax for fiscal years 2010 through 2012 totaling approximately $549 million, subject to interest and penalties. Approximately $535 million of the total additional federal tax for fiscal years 2010 through 2012 relates to proposed adjustments for transfer pricing with the Company’s foreign subsidiaries, intercompany payable balances and the utilization of certain tax attributes. The Company filed a petition with the U.S. Tax Court in March 2019. The U.S. Tax Court consolidated the case for fiscal years 2008 through 2009 with the case for fiscal years 2010 through 2012. On May 4, 2020, the IRS filed with the U.S. Tax Court Amendments to Answer to assert penalties totaling $340 million on the proposed adjustments relating to transfer pricing with respect to fiscal years 2008 through 2009 and fiscal years 2010 through 2012. In September 2020 and December 2020, the IRS proposed adjustments relating to transfer pricing with the Company’s foreign subsidiaries and intercompany payable balances for fiscal years 2013 through 2015 that, if sustained, would result in additional federal tax totaling approximately $343 million. The Company disagrees with the proposed adjustments and continues to believe that its tax positions are properly supported and will vigorously contest the position taken by the IRS.

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 January 1, 2021, it was 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.

As of January 1, 2021, the liability for unrecognized tax benefits (excluding accrued interest and penalties) was approximately $715 million. Accrued interest and penalties related to unrecognized tax benefits as of January 1, 2021 was approximately $146 million. Of these amounts, approximately $724 million could result in potential cash payments. The Company is not able to provide a reasonable estimate of the timing of future tax payments related to these obligations.

Tax

For disclosures regarding statutory notices of deficiency issued by the IRS on June 28, 2018 and December 10, 2018, and petitions filed by the Company with the U.S. Tax Court in September 2018 and March 2019, see Note 12, Income Tax Expense.

Other Matters

In the normal course of business, the Company is subject to 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 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 matters could differ materially from the Company’s expectations.

Item 2.    Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis contains forward-looking statements within the meaning of the federal securities laws, and should be read in conjunction with the disclosures we make concerning risks and other factors that may affect our business and operating results. You should read this information in conjunction with the unaudited Condensed Consolidated Financial Statements and the notes thereto included in this Quarterly Report on Form 10-Q, and the audited Consolidated Financial Statements and notes thereto included in Part II, Item 8 of our Annual Report on Form 10‑K for the fiscal year ended July 3, 2020. See also “Forward-Looking Statements” immediately prior to Part I, Item 1 in this Quarterly Report on Form 10-Q.

Unless otherwise indicated, references herein to specific years and quarters are to our fiscal years and fiscal quarters. As used herein, the terms “we,” “us,” “our,” and the “Company” refer to Western Digital Corporation and its subsidiaries.

Our Company

We are a leading developer, manufacturer and provider of data storage devices and solutions that address the evolving needs of the information technology (“IT”) industry and the infrastructure that enables the proliferation of data in virtually every other industry. We create environments for data to thrive. We drive the innovation needed to help customers capture, preserve, access and transform an ever-increasing diversity of data. Everywhere data lives, from advanced data centers to mobile sensors to personal devices, our industry-leading solutions deliver the possibilities of data.

Our broad portfolio of technology and products address the following key end markets: Client Devices; Data Center Devices and Solutions; and Client Solutions. We also generate license and royalty revenue from our extensive intellectual property (“IP”), which is included in each of these three end market categories.

Our fiscal year ends on the Friday nearest to June 30 and typically consists of 52 weeks. Approximately every five to six years, we report a 53-week fiscal year to align the fiscal year with the foregoing policy. Fiscal year 2021, which ends on July 2, 2021, will be comprised of 52 weeks, with all quarters presented consisting of 13 weeks. Fiscal year 2020, which ended on July 3, 2020, was comprised of 53 weeks, with the first quarter consisting of 14 weeks and the remaining quarters consisting of 13 weeks each.

Key Developments

Business Structure

Late in the first quarter of fiscal 2021, we announced a decision to reorganize our business by forming two separate product business units: flash-based products and hard disk drive (“HDD”). The new structure is intended to provide each business unit with focus and responsibility for identifying current and future customer requirements while driving the strategy, roadmap, pricing and overall profitability for their respective product areas. Beginning in the second fiscal quarter, we are in the process of transitioning to this new operating model and discrete information has not yet been established to align with the new business structure. We are developing new reporting processes to support the new business structure and evaluating the impact of these changes on our discussion and analysis of our financial condition and results of operations in the future.

COVID-19 Pandemic

As a result of the ongoing COVID-19 pandemic, governments and other authorities around the world, including federal, state and local authorities in the United States, have imposed measures intended to reduce its spread, including restrictions on freedom of movement and business operations such as travel bans, border closings, business limitations and closures (subject to exceptions for essential operations and businesses), quarantines and shelter-in-place orders. Although some of these governmental restrictions have since been lifted or scaled back, periodic surges of COVID-19 infections have resulted in the re-imposition of certain restrictions and may lead to other restrictions being re-implemented in response to efforts to reduce the spread of COVID-19. These measures may remain in place for a significant amount of time, and the effects of ongoing vaccination efforts and the emergence of new strains of the virus remain uncertain. In light of these events, we have taken actions to protect the health and safety of our employees while continuing to serve our global customers as an essential business. We have implemented more thorough sanitation practices as outlined by health organizations and instituted social distancing policies at our locations around the world, including working from home, limiting the number of employees attending meetings, reducing the number of people in our sites at any one time, and suspending employee travel. In addition, the responses to COVID-19 taken by others in the supply chain have impacted our operations. As a result, we have incurred
36

charges of approximately $61 million during the six months ended January 1, 2021, primarily related to higher logistics costs, which were recorded in cost of revenue.

As an essential business, we continue to provide products and solutions that enable the proliferation of data and facilitate the sharing of information remotely, which has become more critical as much of the world is interacting from areas of self-isolation. Generally, demand for our products remains solid. During the six months ended January 1, 2021, we experienced lower sales in some of our capacity enterprise and Client Devices products as customers absorbed purchases made in recent quarters, but we also experienced increased sales in retail as COVID-19 restrictions eased, more brick and mortar businesses resumed operations, the work and learn from home trend increased hard drive demand for desktops and notebooks, and gaming increased. Looking forward, we see positive indications of the progression of 5G ramp and the growth of gaming. We also currently expect retail demand to be solid in the near term and HDD to improve as customers absorb recent purchases and we ramp sales of new products. However, the COVID-19 environment remains dynamic and we cannot predict the duration of the pandemic and how demand may change as it develops.

We will continue to actively monitor the situation and may take further actions altering our business operations that we determine are in the best interests of our employees, customers, partners, suppliers, and stakeholders, or as required by federal, state, or local authorities. See “The COVID-19 pandemic could adversely affect our business, results of operations and financial condition” in Part I, Item 1A, Risk Factors, of our Annual Report on Form 10-K for the fiscal year ended July 3, 2020 for more information regarding the risks we face as a result of the COVID-19 pandemic.

Flash Ventures

Through our three business ventures with Kioxia Corporation (“Kioxia”), referred to as “Flash Ventures”, we and Kioxia operate flash-based memory wafer manufacturing facilities in Japan. We are obligated to pay for variable costs incurred in producing our share of Flash Ventures’ flash-based memory wafer supply, based on our three-month forecast, which generally equals 50% of Flash Ventures’ output. In addition, we are obligated to pay for half of Flash Ventures’ fixed costs regardless of the output we choose to purchase. We are also obligated to fund 49.9% to 50% of each Flash Ventures entity’s capital investments to the extent that Flash Ventures entity’s operating cash flow is insufficient to fund these investments. We also co-develop flash technologies (including process technology and memory design) with Kioxia and contribute IP for Flash Ventures’ use.

Since its inception, Flash Ventures’ primary manufacturing site has been located in Yokkaichi, Japan, which currently includes five wafer fabrication facilities. Production levels at the Yokkaichi site were temporarily reduced as a result of an unexpected power outage incident that occurred in the Yokkaichi region on June 15, 2019. The power outage incident impacted the facilities and process tools and resulted in damage to flash wafers in production. The incident resulted in a reduction of our flash wafer availability by approximately 4 exabytes. As a result of this power outage incident, we incurred aggregate charges of $68 million recorded in Cost of revenue in the six months ended January 3, 2020, which primarily consisted of unabsorbed manufacturing overhead costs. During the six months ended January 1, 2021, we recovered $75 million related to this incident from our insurance carriers, which was recorded in Cost of revenue.

In May 2019, we entered into additional agreements with Kioxia to extend Flash Ventures to a new wafer fabrication facility, known as “K1,” located in Kitakami, Japan. The primary purpose of K1 is to provide clean room space to continue the transition of existing flash-based wafer capacity to newer technology nodes. K1 is now fully operational. In connection with the start-up of this facility, we agreed to prepay an aggregate of approximately $360 million over a 3-year period beginning in the first half of fiscal year 2020 toward K1 building depreciation, to be credited against future wafer charges. As of January 1, 2021, remaining committed prepayments totaled $149 million.

In October 2020, Kioxia announced the start of construction of the shell for a new fabrication facility in Yokkaichi, Japan, referred to as “Y7”. We expect to continue Flash Ventures investments into Y7 in due course, following the completion of agreements with Kioxia governing the construction and operation of the new facility and according to then-prevailing market trends.

Net Revenue

Net revenue decreased 7% for the three months ended January 1, 2021 compared to the three months ended January 3, 2020, which reflects an approximate 11 percentage point decline in revenue related to pricing per gigabyte of memory for both HDD and flash products and an approximate 6 percentage point decline in exabyte volume of HDD memory sold, primarily in Data Center Devices and Solutions as discussed further below. These declines were largely offset by higher volumes of flash memory sold.

Client Devices revenue increased 19% year over year. Higher volumes of flash memory contributed 28 percentage points of growth, as work-, school- and game-from-home trends continued to drive demand for our solutions for notebook and desktop applications. Western Digital’s industry leading NVMe-based client SSDs and strong relationships with major PC OEMs drove a record level of exabyte shipments. These increases were slightly offset, in relatively equal portions, by lower average pricing per gigabyte of memory on both HDD and flash products and lower volumes of HDD.

Data Center Devices and Solutions revenue declined 46% year over year due to ongoing cloud digestion, one ongoing qualification delay and China shipment restrictions. Revenue from both capacity enterprise hard drives and enterprise SSDs were down year over year. We believe cloud digestion is abating and are seeing stabilization of OEM demand. Should these demand trends continue, we believe capacity enterprise hard drive revenue bottomed in the second quarter and anticipate a rebound in the third quarter. Within our enterprise SSD product line, we completed the qualification process at a cloud titan for our second-generation product and began shipping to this customer in the third quarter.

Client Solutions revenue increased 6% year over year with approximately 12 percentage points driven by volume growth. The work-, school- and gaming-from-home trends benefited both hard drive and flash-based products. This growth was partially offset by more competitive pricing.

Net revenue decreased 5% for the six months ended January 1, 2021 from the comparable period in the prior year, reflecting an approximate 11 percentage point decline related to pricing per gigabyte of memory for both HDD and flash products and an approximate 8 percentage point decline in HDD memory sold, primarily in Data Center Devices and Solutions. These declines were largely offset by higher volumes of memory, predominantly in flash products. Client Devices revenue increased 19% year over year, with approximately 25 percentage points of growth coming from higher volumes of memory, driven by growth in flash products for the same reasons noted above for the quarter. This increase was partially offset by lower average selling prices per gigabyte of memory in both flash and HDD products. Revenue for Data Center Devices and Solutions declined 36% year over year, which also reflects the drivers noted for the quarter above. Client Solutions revenue was essentially flat year over year, with relatively stable retail demand and pricing in both HDD and flash products.

The changes in net revenue by geography reflect an increase in Asia due to our increased sales of mobility products to manufacturers in the Asia region, and a decrease in the Americas driven by lower sales of capacity enterprise products.

Our top 10 customers accounted for 43% and 41% of our net revenue for the three and six months ended January 1, 2021, respectively, and 44% and 43% for the three and six months ended January 3, 2020, respectively. For the three and six months ended January 1, 2021 and January 3, 2020, no single customer accounted for 10% or more of our net revenue.

Consistent with standard industry practice, we have sales incentive and marketing programs that provide customers with price protection and other incentives or reimbursements that are recorded as a reduction to gross revenue. For the three and six months ended January 1, 2021 and January 3, 2020, these programs represented 20% and 19% and 17% and 16%, respectively, of gross revenues, and adjustments to revenue due to changes in accruals for these programs have generally averaged less than 1% of gross revenue year over year. The increase in adjustments year over year reflects the current competitive environment. The amounts attributed to our sales incentive and marketing programs generally vary according to several factors including industry conditions, list pricing strategies, seasonal demand, competitor actions, channel mix and overall availability of products. Changes in future customer demand and market conditions may require us to adjust our incentive programs as a percentage of gross revenue.

Gross Profit and Gross Margin

Gross profit increased by $25 million for the three months ended January 1, 2021 from the comparable period in the prior year, which reflects a $48 million decrease in charges in the current year related to amortization expense on acquired intangible assets and the $45 million insurance recovery in the current year related to the power outage incident, partially offset by lower revenues.

40

Gross margin increased approximately 3 percentage points for the three months ended January 1, 2021 from the comparable period in the prior year, substantially all of which is attributed to the impacts of the lower charges for amortization of acquired intangible assets and the insurance recovery noted above.

Gross profit increased by $171 million for the six months ended January 1, 2021 from the comparable period in the prior year, which reflects the power outage charges of $68 million incurred in the prior year compared to the $75 million partial recovery in the current year, a $67 million decrease in charges in the current year related to amortization expense on acquired intangible assets and reduced manufacturing costs.

Gross margin increased approximately 10 percentage points for the six months ended January 1, 2021 from the comparable period in the prior year, substantially all of which is attributed to the impacts of the charges related to the power outage incident in the prior year, the insurance recovery in the current year and the lower charges for amortization of acquired intangible assets noted above. Over the near term, we expect flash gross margin to benefit from improved pricing and cost reductions while HDD gross margin is expected to be constrained by the pricing environment for 16-terabyte drives, but we expect improved gross margins over the longer term as we ramp production on higher capacity drives.

Operating Expenses

Research and development (“R&D”) expense decreased $43 million for the three months ended January 1, 2021 from the comparable period in the prior year. The decrease was driven, in comparable amounts, by lower compensation costs, lower travel and entertainment expenses due to the COVID-19 restrictions, and a decline in outside services. R&D expense decreased $62 million for the six months ended January 1, 2021 from the comparable period in the prior year, reflecting the drivers noted above for the quarter, as well as the impact of additional expense in the prior year for the additional week in the prior year.

Selling, general and administrative (“SG&A”) expense decreased $33 million for the three months ended January 1, 2021 from the comparable period in the prior year. The decrease was driven, in comparable amounts, by lower compensation costs, lower travel and entertainment as a result of COVID-19 restrictions and lower consulting and marketing expenses due to event cancellations. SG&A expense decreased $82 million for the six months ended January 1, 2021 from the comparable period in the prior year. Similar to the quarter, the decline was driven, in comparable amounts, by lower compensation costs, lower travel and entertainment as a result of COVID-19 restrictions and lower consulting and marketing expenses due to event cancellations, as well as approximately $10 million of additional expense in the prior year related to the additional week.

Employee termination, asset impairment and other charges increased from the comparable period in the prior year as we initiated incremental actions to align our operations with current market demand. For information regarding employee termination, asset impairment and other charges, see Part I, Item 1, Note 14, Employee Termination, Asset Impairment and Other Charges, of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q.

Interest and Other Income (Expense)

The decreases in total interest and other expense, net for the three and six months ended January 1, 2021 reflect lower interest expense resulting from lower index rates and the pay-down of principal on our debt.

Income Tax Expense

The Tax Cuts and Jobs Act (the “2017 Act”) includes a broad range of tax reform proposals affecting businesses. We completed our accounting for the tax effects of the enactment of the 2017 Act during the second quarter of fiscal 2019. However, the U.S. Treasury and the Internal Revenue Service (“IRS”) have issued tax guidance on certain provisions of the 2017 Act since the enactment date, and we anticipate the issuance of additional regulatory and interpretive guidance. We applied a reasonable interpretation of the 2017 Act along with the then-available guidance in finalizing our accounting for the tax effects of the 2017 Act. Any additional regulatory or interpretive guidance would constitute new information, which may require further refinements to our estimates in future periods.

The following table sets forth income tax information from our Condensed Consolidated Statements of Operations by dollar and effective tax rate:

Income tax expense23 99 80 138 
Effective tax rate27 %(248)%98 %(50)%

The primary drivers of the difference between the effective tax rate for the three and six months ended January 1, 2021 and the U.S. Federal statutory rate of 21% are the relative mix of earnings and losses by jurisdiction, the deduction for foreign derived intangible income, credits, and tax holidays in Malaysia, the Philippines and Thailand that will expire at various dates during fiscal years 2021 through 2030. In addition, the effective tax rate for the three and six months ended January 1, 2021 includes the discrete effects of favorable adjustments proposed by tax authorities of $8 million. The effective tax rate for the six months ended January 1, 2021 also includes the discrete effects of net tax deficiencies from shortfalls of $12 million related to the vesting of stock-based awards and additional tax expense of $10 million from the re-measurement of deferred tax liabilities due to restructuring activities, which have no impact on the amount of income taxes paid by us.

The primary driver of the difference between the effective tax rate for the three and six months ended January 3, 2020 and the U.S. Federal statutory rate of 21% are the relative mix of earnings and losses by jurisdiction, the deduction for foreign derived intangible income, credits, and tax holidays in Malaysia, Philippines and Thailand that expired or will expire at various dates during fiscal years 2020 through 2030.

Our future effective tax rate is subject to future regulatory developments and changes in the mix of our U.S. earnings compared to foreign earnings. Our total tax expense in future fiscal years may also vary as a result of discrete items such as excess tax benefits or deficiencies.

For additional information regarding Income tax expense (benefit), see Part I, Item 1, Note 12, Income Tax Expense, of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q.

We believe our cash, cash equivalents and cash generated from operations as well as our available credit facilities will be sufficient to meet our working capital, debt and capital expenditure needs for at least the next twelve months. Our ability to sustain our working capital position is subject to a number of risks that we discuss in Part I, Item 1A, Risk Factors, in our Annual Report on Form 10-K for the fiscal year ended July 3, 2020.

During fiscal 2021, we expect expenditures for property, plant and equipment for our company plus our portion of the capital expenditures by our Flash Ventures joint venture with Kioxia for its operations to aggregate approximately $3.1 billion. After consideration of the Flash Ventures’ lease financing of its capital expenditures and net operating cash flow, we expect net cash used for our purchases of property, plant and equipment and net activity in notes receivable relating to Flash Ventures to be a cash outflow of approximately $1.0 billion during fiscal 2021. The total expected cash to be used could vary depending on the timing and completion of various capital projects and the availability, timing and terms of related financing.

During fiscal 2019, we determined that it was our intention to repatriate all of our foreign undistributed earnings as a result of the 2017 Act, except a portion of our foreign undistributed earnings, which could result in additional federal taxes based on interpretive guidance issued by the IRS. After consideration of this interpretative guidance affecting the taxation of a certain portion of our foreign undistributed earnings, we determined that we do not intend to repatriate this portion of our foreign undistributed earnings and did not establish an accrual for this liability.

A total of $1.91 billion and $2.28 billion of our Cash and cash equivalents was held outside of the U.S. as of January 1, 2021 and January 3, 2020, respectively. As a result of the change in our permanent reinvestment assertion, there are no material tax consequences that were not previously accrued for on the repatriation of this cash.

Operating Activities

Cash flow from operating activities primarily consists of net income, adjusted for non-cash charges, plus or minus changes in operating assets and liabilities. This represents our principal source of cash. Net cash used for changes in operating assets and liabilities was $78 million for the six months ended January 1, 2021, as compared to $20 million of net cash used for changes in operating assets and liabilities for the six months ended January 3, 2020. Changes in our operating assets and liabilities are largely affected by our working capital requirements, which are dependent on the effective management of our cash conversion cycle as well as timing of payments for taxes. Our cash conversion cycle measures how quickly we can convert our products into cash through sales. The cash conversion cycles were as follows:
Six Months Ended
January 1,
2021
January 3,
2020
(in days)
Days sales outstanding42 38 
Days in inventory109 86 
Days payables outstanding(71)(58)
Cash conversion cycle80 66 

Changes in days sales outstanding (“DSO”) are generally due to the timing of shipments. Changes in days in inventory (“DIO”) are generally related to the timing of inventory builds. Changes in days payables outstanding (“DPO”) are generally related to production volume and the timing of purchases during the period. From time to time, we modify the timing of payments to our vendors. We make modifications primarily to manage our vendor relationships and to manage our cash flows, including our cash balances. Generally, we make the payment term modifications through negotiations with our vendors or by granting to, or receiving from, our vendors’ payment term accommodations.

For the three months ended January 1, 2021, DSO increased by 4 days over the prior year, primarily reflecting the timing of shipments and customer collections. We have seen no significant deterioration in our receivables as a result of COVID-19. DIO increased by 23 days over the prior year, primarily reflecting higher stocking levels of HDD inventory and delays in new product qualifications. With supply chains experiencing disruptions as a result of COVID-19, we are taking actions to ensure that we have the components we need to build products and are stocking higher levels of inventory so that we can ship by ocean and reduce higher cost air freight. DPO increased by 13 days over the prior year, primarily reflecting resumptions of flash production volumes as well as routine variations in the timing of purchases and payments during the period.

43

Investing Activities

Net cash used in investing activities for the six months ended January 1, 2021 primarily consisted of $576 million in capital expenditures, partially offset by a $94 million net decrease in notes receivable issuances to Flash Ventures. Net cash provided by investing activities for the six months ended January 3, 2020 primarily consisted of a $466 million net decrease in notes receivable issuances to Flash Ventures to fund its capital expansion, partially offset by $305 million of capital expenditures.

Our cash equivalents are primarily invested in money market funds that invest in U.S. Treasury securities and U.S. Government agency securities. In addition, from time to time, we invest directly in U.S. Treasury securities, U.S. and international government agency securities, certificates of deposit, asset backed securities and corporate and municipal notes and bonds.

Financing Activities

During the six months ended January 1, 2021, net cash used in financing activities primarily consisted of $461 million for repayment of debt, which included a $300 million voluntary prepayment on our Term Loan B-4. Net cash used in financing activities for the six months ended January 3, 2020 primarily consisted of $707 million for the repayment of our debt and $296 million to pay dividends on our common stock.

In April 2020, we suspended our dividend to reinvest in the business and to support our ongoing deleveraging efforts. We will reevaluate our dividend policy as our leverage ratio improves.
44

Off-Balance Sheet Arrangements

Other than the commitments related to Flash Ventures incurred in the normal course of business and certain indemnification provisions (see “Short and Long-term Liquidity-Contractual Obligations and Commitments” below), we do not have any other material off-balance sheet financing arrangements or liabilities, guarantee contracts, retained or contingent interests in transferred assets, or any other obligation arising out of a material variable interest in an unconsolidated entity. We do not have any majority-owned subsidiaries that are not included in the Condensed Consolidated Financial Statements. Additionally, with the exception of Flash Ventures and our joint venture with Unisplendour Corporation Limited and Unissoft (Wuxi) Group Co. Ltd., we do not have an interest in, or relationships with, any variable interest entities. For additional information regarding our off-balance sheet arrangements, see Part I, Item 1, Note 9, Related Parties and Related Commitments and Contingencies, of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q.

(2)Includes reimbursement for depreciation and lease payments on owned and committed equipment, funding commitments for loans and equity investments and payments for other committed expenses, including R&D and building depreciation. Funding commitments assume no additional operating lease guarantees. Additional operating lease guarantees can reduce funding commitments.

Debt

In addition to our existing debt, we have $2.25 billion available for borrowing under our revolving credit facility, subject to customary conditions under the credit agreement. Additional information regarding our indebtedness, including information about availability under our revolving credit facility and the principal repayment terms, interest rates, covenants and other key terms of our outstanding indebtedness, is included in Part I, Item 1, Note 7, Debt, of the Notes to Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q and in Part II, Item 8, Note 6, Debt, of the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended July 3, 2020. The credit agreement governing our revolving credit facility and Term Loan A-1 requires us to comply with certain financial covenants, consisting of a leverage ratio and an interest coverage ratio. As of January 1, 2021, we were in compliance with these financial covenants.

Flash Ventures

Flash Ventures sells to and leases back from a consortium of financial institutions a portion of its tools and has entered into equipment lease agreements of which we guarantee half or all of the outstanding obligations under each lease agreement. The leases are subject to customary covenants and cancellation events that relate to Flash Ventures and each of the guarantors. The occurrence of a cancellation event could result in an acceleration of the lease obligations and a call on our guarantees. As of January 1, 2021, we were in compliance with all covenants under these Japanese lease facilities. See Part I, Item 1, Note 9, Related Parties and Related Commitments and Contingencies, of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q for information regarding Flash Ventures.

Purchase Obligations and Other Commitments

In the normal course of business, we enter into purchase orders with suppliers for the purchase of components used to manufacture our products. These purchase orders generally cover forecasted component supplies needed for production during the next quarter, are recorded as a liability upon receipt of the components, and generally may be changed or canceled at any time prior to shipment of the components. We also enter into long-term agreements with suppliers that contain fixed future commitments, which are contingent on certain conditions such as performance, quality and technology of the vendor’s components. These arrangements are included under “Purchase obligations and other commitments” in the table above.

Mandatory Deemed Repatriation Tax

The following is a summary of our estimated mandatory deemed repatriation tax obligations that are payable in the following fiscal years (in millions):
January 1,
2021
2022$106 
2023104 
2024179 
2025238 
2026298 
Total$925 

For additional information regarding our estimate of the total tax liability for the mandatory deemed repatriation tax, see Part II, Item 8, Note 13, Income Tax Expense, of the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended June 28, 2019.

Unrecognized Tax Benefits

As of January 1, 2021, the liability for unrecognized tax benefits (excluding accrued interest and penalties) was approximately $715 million. Accrued interest and penalties related to unrecognized tax benefits as of January 1, 2021 was approximately $146 million. Of these amounts, approximately $724 million could result in potential cash payments. We are not able to provide a reasonable estimate of the timing of future tax payments related to these obligations.

Interest Rate Swap

We have generally held a balance of fixed and variable rate debt. At January 1, 2021, we had $5.85 billion of variable rate debt, comprising 63% of the par value of our debt. To balance the portfolio and moderate our exposure to fluctuations in interest rates underlying our variable debt, we entered into pay-fixed interest rate swaps on $2.00 billion notional amount, which effectively converts a portion of our term loan to fixed rates through February 2023. After giving effect to the $2.00 billion of interest rate swaps, we effectively had $3.85 billion of Long-term debt subject to variations in interest rates and a one percent increase in the variable rate of interest would increase annual interest expense by $39 million.

Foreign Exchange Contracts

We purchase foreign exchange contracts to hedge the impact of foreign currency fluctuations on certain underlying assets, liabilities and commitments for Operating expenses and product costs denominated in foreign currencies. For a description of our current foreign exchange contract commitments, see Part I, Item 1, Note 6, Derivative Instruments and Hedging Activities, of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q.

Indemnifications

In the ordinary course of business, we may provide indemnifications of varying scope and terms to customers, vendors, lessors, business partners and other parties with respect to certain matters, including, but not limited to, losses arising out of our breach of agreements, products or services to be provided by us, environmental compliance or from IP infringement claims made by third parties. In addition, we have entered into indemnification agreements with our directors and certain of our officers that will require us, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers. We maintain director and officer insurance, which may cover certain liabilities arising from our obligation to indemnify our directors and officers in certain circumstances.

It is not possible to determine the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Such indemnification agreements may not be subject to maximum loss clauses. Historically, we have not incurred material costs as a result of obligations under these agreements.
47


Stock Repurchase Program

Our Board of Directors has authorized a stock repurchase program for the repurchase of up to $5.0 billion of our common stock, which authorization is effective through July 25, 2023. We did not make any stock repurchases during the six months ended January 1, 2021 and have not repurchased any shares of our common stock pursuant to our stock repurchase program since the first quarter of fiscal 2019. Although we will reevaluate the repurchasing of our common stock when appropriate, there can be no assurance if, when or at what level we may resume such activity. The remaining amount available to be repurchased under our current stock repurchase program as of January 1, 2021 was $4.5 billion. Repurchases under the stock repurchase program may be made in the open market or in privately negotiated transactions and may be made under a Rule 10b5-1 plan.

Cash Dividend

We issued a quarterly cash dividend from the first quarter of fiscal 2013 through the third quarter of fiscal 2020. In April 2020, we suspended our dividend to reinvest in the business and to support our ongoing deleveraging efforts. We will reevaluate our dividend policy as our leverage ratio improves.

Recent Accounting Pronouncements

For a description of recently issued and adopted accounting pronouncements, including the respective dates of adoption and expected effects on our results of operations and financial condition, see Part I, Item 1, Note 2, Recent Accounting Pronouncements, of the Notes to Condensed Consolidated Financial Statements included in this Quarterly Report on Form 10-Q.

Critical Accounting Policies and Estimates

We have prepared the accompanying unaudited Condensed Consolidated Financial Statements in accordance with accounting principles generally accepted in the United States (U.S. GAAP). The preparation of the financial statements requires the use of judgments and estimates that affect the reported amounts of revenues, expenses, assets, liabilities and shareholders’ equity. We have adopted accounting policies and practices that are generally accepted in the industry in which we operate. If these estimates differ significantly from actual results, the impact to the Condensed Consolidated Financial Statements may be material.

There have been no material changes in our critical accounting policies and estimates from those disclosed in our Annual Report on Form 10‑K for the fiscal year ended July 3, 2020. Please refer to Part II, Item 7 of our Annual Report on Form 10‑K for the fiscal year ended July 3, 2020 for a discussion of our critical accounting policies and estimates.
48

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

There have been no material changes to our market risk during the six months ended January 1, 2021. For a discussion of our exposure to market risk, see Part II, Item 7A, “Quantitative and Qualitative Disclosures About Market Risk” in our Annual Report on Form 10-K for the fiscal year ended July 3, 2020.


Item 4.    Controls and Procedures

As required by Rule 13a-15(b) promulgated by the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rule 13a-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures were effective.

There were no changes in our internal control over financial reporting that occurred during our most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

We are implementing an enterprise resource planning (“ERP”) system on a worldwide basis, which is expected to improve the efficiency of certain financial and related transactional processes. The gradual implementation is expected to occur in phases over the next several years. We have completed the implementation of certain processes, including the financial consolidation and reporting, fixed assets, supplier management and indirect procure-to-pay processes, and have revised and updated the related controls. These changes did not materially affect our internal control over financial reporting. As we implement the remaining functionality under this ERP system over the next several years, we will continue to assess the impact on our internal control over financial reporting.

Item 1A.    Risk Factors

We have described under the heading “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended July 3, 2020 risks and uncertainties that could cause our actual results of operations and financial condition to vary materially from past, or from anticipated future, results of operations and financial condition. There have been no material changes from these risk factors previously described in our Annual Report on Form 10-K for the fiscal year ended July 3, 2020. These risks and uncertainties are not the only risks facing us. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also adversely affect our business, financial condition, results of operations or the market price of our common stock.
