Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The Company Marvell Technology Group Ltd., a Bermuda exempted company, and its subsidiaries (the “Company”), is a fabless semiconductor provider of high-performance application-specific standard products. The Company’s core strength is the development of complex System-on-a-Chip devices, leveraging its extensive technology portfolio of intellectual property in the areas of analog, mixed-signal, digital signal processing, and embedded and standalone integrated circuits. The Company also develops platforms that it defines as integrated hardware along with software that incorporates digital computing technologies designed and configured to provide an optimized computing solution. The Company’s broad product portfolio includes devices for networking and storage. Basis of Presentation The Company’s fiscal year is the 52- or 53-week period ending on the Saturday closest to January 31. Accordingly, every fifth or sixth fiscal year will have a 53-week period. The additional week in a 53-week year is added to the fourth quarter, making such quarter consist of 14 weeks. Fiscal 2021, fiscal 2020 and fiscal 2019 each had a 52-week period. Certain prior period amounts have been reclassified to conform to current year presentation. On October 29, 2020, the Company entered into a merger agreement (the “Merger Agreement”) with Inphi Corporation (“Inphi”), whereby the Company will pay Inphi's stockholders $66 per share in cash and 2.323 common shares for each Inphi share, which represented purchase consideration of approximately $10.0 billion as of that date. The Company intends to fund the cash consideration with $4.25 billion in debt financing, and has obtained commitments consisting of a $2.5 billion bridge loan commitment, a $875 million 3-year term loan facility commitment and a $875 million 5-year term loan facility commitment from JP Morgan Chase Bank, N.A., in each case subject to customary terms and conditions. The transaction is not subject to financing conditions. As of January 30, 2021, there was $33.4 million of associated deferred debt financing and equity issuance costs, of which $11.7 million is included in prepaid expenses and other current assets, and $21.7 million is included in other non-current assets on the accompanying consolidated balance sheet as of January 30, 2021. The transaction is expected to close in the second half of calendar 2021, pending approval by Inphi's and the Company's stockholders, as well as regulatory approval and satisfaction of other customary closing conditions. As a result of the transaction, the parent company will be domiciled in the United States upon closing of the transaction. For periods after closing, the combined company will be subject to taxation in the United States, which may adversely impact the Company's future effective tax rates and tax liabilities. A fee of up to $460.0 million may be payable by the Company or $300.0 million payable by Inphi upon termination of the transaction, as more fully described in the Merger Agreement. If the Merger Agreement is terminated due to failure to obtain stockholder approval, the party whose stockholders did not approve the transaction will be obligated to reimburse the other party up to $25.0 million for its merger related fees and costs.

Accounting Policies [Abstract]

Significant Accounting Policies

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent liabilities. On an ongoing basis, the Company evaluates its estimates, including those related to performance-based compensation, revenue recognition, provisions for sales returns and allowances, inventory excess and obsolescence, investment fair values, goodwill and other intangible assets, restructuring, income taxes, litigation and other contingencies. Actual results could differ from these estimates, and such differences could affect the results of operations reported in future periods. In the current macroeconomic environment affected by COVID-19, these estimates require increased judgment and carry a higher degree of variability and volatility. As events continue to evolve and additional information becomes available, these estimates may change materially in future periods.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All inter-company accounts and transactions have been eliminated. The functional currency of the Company and its subsidiaries is the U.S. dollar.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less from the date of purchase to be cash equivalents. Cash and cash equivalents consist of cash on deposit with banks and time deposits.

Concentration of Credit Risk and Significant Customers

Financial instruments that potentially subject the Company to a significant concentration of credit risk consist principally of cash equivalents and accounts receivable. Cash and cash equivalents are maintained with high-quality financial institutions, the composition and maturities of which are regularly monitored by management. The Company believes that the concentration of credit risk in its trade receivables is substantially mitigated by the Company’s credit evaluation process, relatively short collection terms and the high level of credit worthiness of its customers. The Company performs ongoing credit evaluations of its customers’ financial conditions and limits the amount of credit extended when deemed necessary based upon payment history and the customer’s current credit worthiness, but generally requires no collateral. The Company regularly reviews the allowance for bad debt and doubtful accounts by considering factors such as historical experience, credit quality, reasonable and supportable forecasts, age of the accounts receivable balances and current economic conditions that may affect a customer’s ability to pay.

The Company’s accounts receivable was concentrated with four customers at January 30, 2021, who comprise a total of 53% of gross accounts receivable, compared with four customers at February 1, 2020, who represented 38% of gross accounts receivable, respectively. This presentation is at the customer consolidated level.

Historically, a relatively small number of customers have accounted for a significant portion of our net revenue. During fiscal 2021, there was no net revenue attributable to one customer, other than one distributor, whose revenue was 10% or greater of total net revenues. Net revenue attributable to significant customers whose revenues as a percentage of net revenue was 10% or greater of total net revenues is presented in the following table:

Year Ended

January 30, 2021

February 1, 2020

Seagate

Distributor:

Wintech

* Less than 10% of net
** The percentage of net revenue reported for Toshiba for fiscal year 2019 excludes net revenue of Toshiba Memory Corporation after Toshiba divested Toshiba Memory Corporation during fiscal year 2019.

The Company continuously monitors the creditworthiness of its distributors and believes these distributors’ sales to diverse end customers and to diverse geographies further serve to mitigate the Company’s exposure to credit risk.

Inventories

Inventory is stated at the lower of cost or net realizable value, cost being determined under the first-in, first-out method. The total carrying value of the Company’s inventory is reduced for any difference between cost and estimated net realizable value of inventory that is determined to be excess, obsolete or unsellable inventory based upon assumptions about future demand and market conditions. If actual future demand for the Company’s products is less than currently forecasted, the Company may be required to write inventory down below the current carrying value. Once the carrying value of inventory is reduced, it is maintained until the product to which it relates is sold or otherwise disposed. Inventoriable shipping and handling costs are classified as a component of cost of goods sold in the consolidated statements of operations.

Property and Equipment, Net

Property and equipment, net, are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which ranges from 2 to 7 years for machinery and equipment, and 3 to 4 years for computer software, and furniture and fixtures. Buildings are depreciated over an estimated useful life of 30 years and building improvements are depreciated over estimated useful lives of 15 years. Leasehold improvements are depreciated over the shorter of the remaining lease term or the estimated useful life of the asset.

Goodwill

Goodwill is recorded when the consideration paid for a business acquisition exceeds the fair value of net tangible and intangible assets acquired. Goodwill is measured and tested for impairment annually on the last business day of the fiscal fourth quarter and whenever events or changes in circumstances indicate the carrying amount of goodwill may not be recoverable. The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount or the Company may determine to proceed directly to the quantitative impairment test.

If the Company assesses qualitative factors and concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount or if the Company determines not to use the qualitative assessment, then a quantitative impairment test is performed. The quantitative impairment test requires comparing the fair value of the reporting unit to its carrying value, including goodwill. The Company has identified that its business operates as a single operating segment with two components (Networking and Storage), which it has concluded can be aggregated into a single reporting unit for purposes of testing goodwill impairment. An impairment exists if the fair value of the reporting unit is lower than its carrying value. If the fair value of the reporting unit is lower than its carrying value, the Company would record an impairment loss in the fiscal quarter in which the determination is made.

Long-Lived Assets and Intangible Assets

The Company assesses the impairment of long-lived assets and intangible assets whenever events or changes in circumstances indicate that the carrying amount of long-lived assets may not be recoverable. The Company estimates the future cash flows, undiscounted and without interest charges, expected to be generated by the assets from its use or eventual disposition. If the sum of the expected undiscounted future cash flows is less than the carrying amount of those assets, the Company recognizes an impairment loss based on the excess of the carrying amount over the fair value of the assets. Please see “Note 5 - Goodwill and Acquired Intangible Assets, Net” for further details regarding impairment of acquisition-related identified intangible assets.

Acquisition-related identified intangible assets are amortized on a straight-line basis over their estimated economic lives, except for certain customer contracts and related relationships, which are amortized using an accelerated method of amortization over the expected customer lives. In-process research and development (“IPR&D”) is not amortized until the completion of the related development.

Leases

The Company determines if an arrangement is a lease at inception. Operating lease right-of-use (“ROU”) assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Operating lease ROU assets also include any initial direct costs and prepayments less lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options. As the Company's leases do not provide an implicit rate, the Company uses its collateralized incremental borrowing rate based on the information available at the lease commencement date, including lease term, in determining the present value of lease payments. Lease expense for these leases is recognized on a straight line basis over the lease term.

Foreign Currency Transactions

The functional currency of all of the Company’s non-United States (“U.S.”) operations is the U.S. dollar. Monetary accounts maintained in currencies other than the U.S. dollar are re-measured using the foreign exchange rate at the balance sheet date. Operational accounts and nonmonetary balance sheet accounts are measured and recorded at the exchange rate in effect at the date of the transaction. The effects of foreign currency re-measurement are reported in current operations.

Revenue Recognition

Product revenue is recognized at a point in time when control of the asset is transferred to the customer. Substantially all of the Company's revenue is derived from product sales. The Company recognizes revenue when it satisfies a performance obligation by transferring control of a product to a customer in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. For product revenue, the performance obligation is deemed to be the delivery of the product and therefore, the revenue is generally recognized upon shipment to customers, net of accruals for estimated sales returns and rebates. These estimates are based on historical returns analysis and other known factors. The Company accounts for rebates by recording reductions to revenue for rebates in the same period that the related revenue is recorded. The amount of these reductions is based upon the terms agreed to with the customer. Product revenue on sales made to distributors with price protection, price discounts and stock rotation rights is recognized upon shipment to distributors, with an accrual for the variable consideration aspect of sales to distributors, estimated based on historical experience, including estimates for price discounts, price protection, rebates, and stock rotation programs.

A portion of the Company's net revenue is derived from sales through third-party logistics providers who maintain warehouses in close proximity to our customer’s facilities. Revenue from sales through these third-party logistics providers is not recognized until the product is pulled from stock by the customer.

The Company’s products are generally subject to warranty, which provides for the estimated future costs of replacement upon shipment of the product. The Company’s products carry a standard one-year warranty, with certain exceptions in which the warranty period can extend to more than one year based on contractual agreements. The warranty accrual is estimated primarily based on historical claims compared to historical revenues and assumes that the Company will have to replace products subject to a claim. From time to time, the Company becomes aware of specific warranty situations, and it records specific accruals to cover these exposures. Warranty expenses were not material for the periods presented.

Business Combinations

The Company allocates the fair value of the purchase consideration of its acquisitions to the tangible assets, liabilities, and intangible assets acquired, including IPR&D, based on their estimated fair values. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. IPR&D is initially capitalized at fair value as an intangible asset with an indefinite life and assessed for impairment thereafter. When an IPR&D project is completed, the IPR&D is reclassified as an amortizable purchased intangible asset and amortized over the asset’s estimated useful life. Acquisition-related expenses and related restructuring costs are recognized separately from the business combination and are expensed as incurred.

Advertising Expense

Advertising costs are expensed as incurred. The Company recorded $0.6 million, $0.8 million and $0.2 million of advertising costs for fiscal 2021, 2020 and 2019, respectively, included in selling, general and administrative expenses in the consolidated statements of operations.

Share-Based Compensation

Share-based compensation is measured at the grant date, based on the fair value of the award, and is recognized as expense over the requisite service vesting period. The Company amortizes share-based compensation expense for time-based awards under the straight-line attribution method over the vesting period. Share-based compensation expense for performance-based awards is recognized when it becomes probable that the performance conditions will be met. The Company amortizes share-based compensation expense for performance-based awards using the accelerated method.

The fair value of each restricted stock unit is estimated based on the market price of the Company’s common shares on the date of grant less the expected dividend yield.

The Company estimates the fair value of stock purchase awards on the date of grant using the Black Scholes option-pricing model. The fair value of performance-based awards based on total shareholder return (“TSR”) and value creation (“VCA”) awards are estimated on the date of grant using a Monte Carlo simulation model.

Forfeitures are recorded when they occur. Previously recognized expense is reversed for the portion of awards forfeited prior to vesting as and when forfeitures occur.

Comprehensive Income (Loss)

Comprehensive income (loss), net of tax is comprised of net income and net change in unrealized gains and losses, on available-for-sale securities and cash flow hedges.

Accounting for Income Taxes

The Company estimates its income taxes in the jurisdictions in which it operates. This process involves estimating the Company's actual tax exposure together with assessing temporary differences resulting from the differing treatment of certain items for tax return and financial statement purposes. These differences result in deferred tax assets and liabilities, which are included in the Company's consolidated balance sheets.

The Company recognizes income taxes using an asset and liability approach. This approach requires the recognition of taxes payable or refundable for the current year, and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in the Company's consolidated financial statements or tax returns. The measurement of current and deferred taxes is based on provisions of the enacted tax law and the effects of future changes in tax laws or rates are not anticipated.

Evaluating the need for an amount of a valuation allowance for deferred tax assets requires judgment and analysis of all the positive and negative evidence available, including cumulative losses in recent years and projected future taxable income, to determine whether all or some portion of the deferred tax assets will not be realized. Using available evidence and judgment, the Company establishes a valuation allowance for deferred tax assets, when it determines that it is more likely than not that they will not be realized. Valuation allowances have been provided primarily against the U.S. research and development credits. Valuation allowances have also been provided against certain acquired net operating losses and the deferred tax assets of foreign subsidiaries. A change in the assessment of the realizability of deferred tax assets may materially impact the Company's tax provision in the period in which a change occurs. Taxes due on future Global Intangible Low-Taxed Income (GILTI) inclusions in U.S. are recognized as a current period expense when incurred.

As a multinational corporation, the Company conducts its business in many countries and is subject to taxation in many jurisdictions. The taxation of the business is subject to the application of various and sometimes conflicting tax laws and regulations as well as multinational tax conventions. The Company's effective tax rate is highly dependent upon the geographic distribution of the Company's worldwide earnings or losses, the tax laws and regulations in various localities, the availability of tax incentives, tax credits and loss carryforwards, and the effectiveness of the Company's tax planning strategies, including the Company's estimates of the fair value of its intellectual property. The application of tax laws and regulations is subject to legal and factual interpretation, judgment and uncertainty. Tax laws themselves are subject to change as a result of changes in fiscal policy, changes in legislation, and the evolution of regulations and court rulings. Consequently, taxing authorities may impose tax assessments or judgments against us that could materially affect the Company's tax liability and/or effective income tax rate.

The Company is subject to income tax audits by tax authorities in the jurisdictions in which it operates. The Company recognizes the effect of income tax positions only if these positions are more likely than not to be sustained. Recognized income tax positions are measured at the largest amount that is more than 50% likely to be realized. Changes in judgment regarding the recognition or measurement of uncertain tax positions are reflected in the period in which the change occurs. The Company records interest and penalties related to unrecognized tax benefits in income tax expense. The calculation of the Company's tax liabilities involves the inherent uncertainty associated with complex tax laws. The Company believes it has adequately provided for in its financial statements additional taxes that it estimates may be required to be paid as a result of such examinations. While the Company believes that it has adequately provided for all tax positions, amounts asserted by tax authorities could be greater or less than its accrued position. Unpaid tax liabilities, including the interest and penalties, are released pursuant to a final settlement with tax authorities, completion of audit or expiration of various statutes of limitation. The material jurisdictions in which the Company may be subject to potential examination by tax authorities throughout the world include China, India, Israel, Singapore, Germany, and the United States.

The recognition and measurement of current taxes payable or refundable, and deferred tax assets and liabilities require that the Company make certain estimates and judgments. Changes to these estimates or judgments may have a material effect on the Company's tax provision in a future period.

Recent Accounting Pronouncements

Accounting Pronouncements Recently Adopted

In June 2016, the FASB issued a new standard requiring financial assets measured at amortized cost be presented at the net amount expected to be collected, through an allowance for credit losses that is deducted from the amortized cost basis. The standard eliminates the threshold for initial recognition in current GAAP and reflects an entity’s current estimate of all expected credit losses. The measurement of expected credit losses is based on historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the financial assets. The new standard was adopted by the Company on February 2, 2020 and did not have a material effect on the Company's consolidated financial statements.

In August 2018, the FASB issued an accounting standards update to align the requirements for capitalizing implementation costs incurred in a software hosting arrangement that is a service contract and costs to develop or obtain internal-use software. The new standard was adopted by the Company on February 2, 2020 on a prospective basis and did not have a material effect on the Company's consolidated financial statements.

In August 2018, the FASB issued an accounting standards update that modifies the disclosure requirements on fair value measurements. The new guidance adds, modifies and removes certain fair value measurement disclosure requirements. The new standard was adopted by the Company on February 2, 2020 and did not have a material effect on the Company's consolidated financial statements.

In November 2018, the FASB issued an accounting standards update that clarifies when transactions between participants in a collaborative arrangement are within the scope of the new revenue recognition standard that the Company adopted at the beginning of fiscal 2019. The new standard was adopted by the Company on February 2, 2020 and did not have a material effect on the Company's consolidated financial statements.

Accounting Pronouncements Not Yet Effective

In December 2019, the FASB issued an accounting standards update that simplifies the accounting for income taxes by eliminating certain exceptions related to the approach for intraperiod tax allocation and modified the methodology for calculating income taxes in an interim period. It also clarifies and simplifies other aspects of the accounting for income taxes. The guidance is effective for the Company beginning in the first quarter of fiscal year 2022, with early adoption permitted. The new standard was adopted by the Company on January 31, 2021 on a prospective basis and is not expected to have a material effect on the Company's consolidated financial statements.

Contract Liabilities

Contract liabilities consist of the Company’s obligation to transfer goods or services to a customer for which the Company has received consideration or the amount is due from the customer. As of January 30, 2021, contract liability balances are comprised of variable consideration estimated based on a portfolio basis using the expected value methodology based on analysis of historical data, current economic conditions, and contractual terms. Variable consideration estimates consist of the estimated returns, price discounts, price protection, rebates, and stock rotation programs. As of the end of a reporting period, some of the performance obligations associated with contracts will have been unsatisfied or only partially satisfied. In accordance with the practical expedients available in the guidance, the Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected duration of one year or less. Contract liabilities are included in accrued liabilities in the consolidated balance sheets.

The opening balance of contract liabilities at the beginning of fiscal year 2021 was $111.5 million. During the year ended January 30, 2021, contract liabilities increased by $875.0 million associated with variable consideration estimates, offset by $805.5 million decrease in such reserves primarily due to credit memos issued to customers. The ending balance of contract liabilities at the end of fiscal year 2021 was $181.0 million. The amount of revenue recognized during the year ended January 30, 2021 that was included in the contract liabilities balance at February 1, 2020 was not material.

Sales Commissions

The Company has elected to apply the practical expedient to expense commissions when incurred as the amortization period is typically one year or less. These costs are recorded in selling, general and administrative expenses in the consolidated statements of operations.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Business Combinations [Abstract]

Business Combinations

Avera

On November 5, 2019, the Company completed the acquisition of Avera, the ASIC business of GlobalFoundries. Avera is a leading provider of ASIC semiconductor solutions. The Company acquired Avera to expand its ASIC design capabilities. Total purchase consideration consisted of cash consideration paid to GlobalFoundries of $593.5 million, net of working capital and other adjustments. An additional $90 million in cash would have been paid to acquire additional assets if certain conditions were satisfied. In July 2020, GlobalFoundries and the Company agreed to terminate this requirement to acquire the additional assets.

The factors contributing to the recognition of goodwill were based upon the Company's conclusion that there are strategic and synergistic benefits that are expected to be realized from the acquisition. A portion of the goodwill recorded for the Avera acquisition is deductible for tax purposes.

The purchase price allocation is as follows (in thousands):


	Previously Reported February 1, 2020 (Provisional)		Measurement Period Adjustment		January 30, 2021
Inventories	$	106,465	$	—	$	106,465

Other non-current liabilities	(650)		—		(650)
	$	593,500	$	—	$	593,500

The previously reported provisional amounts presented in the table above pertained to the preliminary purchase price allocation reported in the Company's Form 10-K for the year ended February 1, 2020. The measurement period adjustments were primarily related to changes in estimates related to final agreement of tax-related purchase price allocations with the seller. The Company does not believe that the measurement period adjustments had a material impact on its consolidated statements of operations, balance sheets or cash flows in any periods reported.

In fiscal year 2020, the Company incurred total acquisition related costs of $5.7 million which were recorded in selling, general and administrative expense in the consolidated statements of operations.

Aquantia Corp

On September 19, 2019, the Company completed the acquisition of Aquantia. Aquantia is a manufacturer of high-speed transceivers which includes copper and optical physical layer products. The Company acquired Aquantia to further its position in automotive in-vehicle networking and strengthen its multi-gig ethernet PHY portfolio for enterprise infrastructure, data center and access applications. In accordance with the terms of the Agreement and Plan of Merger dated May 6, 2019, by and among the Company and Aquantia (the “Aquantia merger agreement”), the Company acquired all outstanding shares of common stock of Aquantia (the “Aquantia shares”) for $13.25 per share in cash. The merger consideration was funded with a combination of cash on hand and funds from the Company's revolving line of credit (“2018 Revolving Credit Facility”). See “Note 11 - Debt” for additional information.

The following table summarizes the total merger consideration (in thousands):


Cash consideration to Aquantia common stockholders	$	479,547
Cash consideration - director, employee & consultant grant accelerations and payout for employee stock purchase plan	7,122
Stock consideration for replacement equity awards attributable to pre-combination service	15,520
Total merger consideration	$	502,189

The factors contributing to the recognition of goodwill were based upon the Company's conclusion that there are strategic and synergistic benefits that are expected to be realized from the acquisition. Goodwill recorded for the Aquantia acquisition is not expected to be deductible for tax purposes.

The purchase price allocation is as follows (in thousands):


	Previously Reported February 1, 2020 (Provisional)		Measurement Period Adjustment		January 30, 2021

	$	502,189	$	—	$	502,189

The previously reported provisional amounts presented in the table above pertained to the preliminary purchase price allocation reported in the Company's Form 10-K for the year ended February 1, 2020. The measurement period adjustments were primarily related to changes in estimates related to finalizing Aquantia's U.S. tax return. The Company does not believe that the measurement period adjustments had a material impact on its consolidated statements of operations, balance sheets or cash flows in any periods reported.

In fiscal year 2020, the Company incurred total acquisition related costs of $5.3 million which were recorded in selling, general and administrative expense in the consolidated statements of operations.

Cavium Inc

On July 6, 2018, the Company completed the acquisition of Cavium (the “Cavium acquisition”). Cavium is a provider of highly integrated semiconductor processors that enable intelligent processing for wired and wireless infrastructure and cloud for networking, communications, storage and security applications. The Cavium acquisition was primarily intended to create an opportunity for the combined company to emerge as a leader in infrastructure solutions. In accordance with the terms of the Agreement and Plan of Merger, dated as of November 19, 2017, by and among the Company and Cavium (the “Cavium merger agreement”), the Company acquired all outstanding shares of common stock of Cavium (the “Cavium shares”) for $40.00 per share in cash and 2.1757 shares of the Company's common stock exchanged for each share of Cavium stock. The Company also made cash payments for the fractional shares that resulted from conversion as specified in the Cavium merger agreement. The merger consideration was funded with a combination of cash on hand, new debt financing and issuance of the Company’s common shares. See “Note 11 - Debt” for discussion of the debt financing.

The following table summarizes the total merger consideration (in thousands, except share and per share data):


Cash consideration to Cavium common stockholders	$	2,819,812
Common stock (153,376,408 shares of the Company's common stock at $21.34 per share)	3,273,053

Stock consideration for employee accelerated awards attributable to pre-acquisition service	7,804
Fair value of the replacement equity awards attributable to pre-acquisition service	50,485
Total merger consideration	$	6,161,796

The factors contributing to the recognition of goodwill were based upon the Company's conclusion that there are strategic and synergistic benefits that are expected to be realized from the acquisition. Goodwill of $3.5 billion recorded for the Cavium acquisition is not expected to be deductible for tax purposes.

The purchase price allocation is as follows (in thousands):

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Acquired Intangible Assets, Net

Goodwill

Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. The carrying value of goodwill as of January 30, 2021 and February 1, 2020 is $5.3 billion. See “Note 4 - Business Combinations” for discussion of the acquisitions and changes to the carrying value of goodwill.

The Company has identified that its business operates as a single operating segment with two components that it has concluded can be aggregated into a single reporting unit. The Company’s annual test for goodwill impairment as of the last day of the fourth quarter of fiscal 2021 did not result in any impairment charge.

There was no activity from acquisitions or divestitures recorded to goodwill in fiscal 2021 and 2020 other than those described above.

Acquired Intangible Assets, Net

In connection with the Cavium acquisition on July 6, 2018, the Aquantia acquisition on September 19, 2019 and the Avera acquisition on November 5, 2019, the Company recognized $3.3 billion of intangible assets. As of January 30, 2021 and February 1, 2020, net carrying amounts are as follows (in thousands, except for weighted-average remaining amortization period):


	January 30, 2021
	Gross Carrying Amounts		Accumulated Amortization and Write-Offs		Net Carrying Amounts		Weighted -Average Remaining Amortization Period (Years)
Developed technologies	$	2,454,000	$	(724,215)	$	1,729,785	5.54
Customer contracts and related relationships	643,000		(228,845)		414,155		5.62
Trade names	23,000		(14,240)		8,760		2.20
Total acquired amortizable intangible assets	3,120,000		(967,300)		2,152,700		5.54
IPR&D	118,000		—		118,000		n/a
Total acquired intangible assets	$	3,238,000	$	(967,300)	$	2,270,700

The Company regularly analyzes the results of its business to determine whether events or circumstances exist that indicate whether the carrying amount of the intangible assets may not be recoverable. During the second quarter of fiscal 2021, impairment charges of $50.3 million related to certain intangible assets acquired from Cavium were recognized as part of restructuring actions. The gross carrying amounts and the accumulated amortization of those impaired intangible assets were excluded from the table above. See “Note 6 - Restructuring” for additional information.


	February 1, 2020
	Gross Carrying Amounts		Accumulated Amortization and Write-Offs		Net Carrying Amounts		Weighted-Average Remaining Amortization Period (Years)
Developed technologies	$	2,511,000	$	(413,735)	$	2,097,265	6.41
Customer contracts and related relationships	643,000		(128,939)		514,061		6.61
Trade names	23,000		(8,726)		14,274		2.96
Total acquired amortizable intangible assets	3,177,000		(551,400)		2,625,600		6.43
IPR&D	139,000		—		139,000		n/a
Total acquired intangible assets	$	3,316,000	$	(551,400)	$	2,764,600

The intangible assets are amortized on a straight-line basis over the estimated useful lives, except for certain Cavium customer contracts and related relationships, which are amortized using an accelerated method of amortization over the expected customer lives in order to more closely align with the pattern of realization of economic benefits expected to be obtained. The IPR&D will be accounted for as an indefinite-lived intangible asset and will not be amortized until the underlying projects reach technological feasibility and commercial production at which point the IPR&D will be amortized over the estimated useful life. Useful lives for these IPR&D projects are expected to range between 3 to 10 years. In the event the IPR&D is abandoned, the related assets will be written off.

Amortization for acquired intangible assets was $443.6 million, $368.1 million and $183.3 million during the years ended January 30, 2021, February 1, 2020 and February 2, 2019 respectively.

Fiscal 2021. The Company recorded $180.4 million of restructuring and other related charges during its evaluation of its existing operations to increase operational efficiency, decrease costs and increase profitability. The charges include $119.0 million associated with the server processor product line described below and $61.4 million recorded in connection with prior acquisitions. The Company expects to complete these restructuring actions by the end of fiscal 2022.

During the second quarter of fiscal 2021, the Company made changes to the scope of its server processor product line in response to changes in the associated market. The Company transitioned its product offering from standard server processors to the broad server market to focus only on customized server processors for a few targeted customers. This change in strategy required the Company to assess whether the carrying value of the associated assets would be recoverable. As a result of the assessment, the Company determined the carrying amount of certain impacted assets were not recoverable, which resulted in recognition of $119.0 million of restructuring related charges associated with the server processor product line during the second quarter of fiscal 2021. The charges included $50.3 million in impairment of acquired intangibles, $36.0 million in impairment of purchased IP licenses and $32.7 million in equipment and inventory impairment and other related restructuring charges.

The remaining restructuring charges of $61.4 million include approximately $36.9 million in severance and related costs, $15.7 million in facilities and related costs, and $8.8 million in other exit-related costs. The severance costs primarily relate to the employee separation costs in connection with the acquisitions. The facility and related costs primarily relate to the remaining payments under lease obligations upon vacating certain worldwide office locations, and ongoing operating expenses of vacated facilities.

Fiscal 2020. The Company recorded $55.3 million of restructuring and other related charges in connection with the acquisitions as described in “Note 4 - Business Combinations.” Following the acquisition of Avera, the Company reviewed its financial position and operating results against the Company's strategic objectives, long-term operating targets and other operational priorities and initiated a restructuring plan in an effort to increase operational efficiency, decrease costs and increase profitability. The charges include $15.4 million recorded in connection with the Avera acquisition and $39.9 million recorded in connection with the other acquisitions.

The charges include approximately $31.2 million in severance and related costs, $20.0 million in facilities and related costs, and $4.1 million in other exit-related costs. The severance costs primarily relate to the employee separation costs in connection with the acquisitions. The facility and related costs primarily relate to the remaining payments under lease obligations upon vacating certain worldwide office locations, and ongoing operating expenses of vacated facilities.

Fiscal 2019. The Company recorded $76.8 million of restructuring and other related charges in fiscal 2019 in connection with the Cavium acquisition as described in “Note 4 - Business Combinations.” The charges include approximately $39.1 million in severance and related costs, $35.8 million in facilities and related costs and $1.9 million in other exit-related costs. Other exit-related costs include $12.0 million for the impairment of equipment and technology licenses, offset by a gain of $12.2 million from the sale of a building in Singapore.

The following table sets forth a reconciliation of the beginning and ending restructuring liability balances by each major type of costs associated with the restructuring charges (in thousands):

The remaining accrued severance and related costs are expected to be paid in fiscal 2022. The remaining other exit-related costs includes impairment charges associated with the future maintenance support for the server processor product line that are expected to be paid through fiscal 2024. The remaining accrued facility and related costs includes remaining payments under lease obligations related to vacated space that are expected to be paid through fiscal 2028.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair value is an exit price representing the amount that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, the accounting guidance establishes a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:

Level 1 — Observable inputs that reflect quoted prices for identical assets or liabilities in active markets.

Level 2 — Other inputs that are directly or indirectly observable in the marketplace.

Level 3 — Unobservable inputs that are supported by little or no market activity.

The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

The Company’s Level 1 assets include institutional money-market funds that are classified as cash equivalents, which are valued primarily using quoted market prices. The Company’s Level 2 assets include its marketable investments in time deposits, as the market inputs used to value these instruments consist of market yield. In addition, the severance pay fund is classified as Level 2 assets as the valuation inputs are based on quoted prices and market observable data of similar instruments.

The tables below set forth, by level, the Company’s assets and liabilities that are measured at fair value on a recurring basis. The tables do not include assets and liabilities that are measured at historical cost or any basis other than fair value (in thousands):

There were no transfers of assets between levels in either fiscal 2021 or 2020.

Fair Value of Debt

The Company classified the Term Loan, the 2023 Notes and 2028 Notes under Level 2 of the fair value measurement hierarchy. The carrying value of the Term Loan approximates its fair value as the Term Loan is carried at a market observable interest rate that resets periodically. At January 30, 2021, the estimated aggregate fair value of the 2023 Notes and 2028 Notes was $1.1 billion and were classified as Level 2 as there are quoted prices from less active markets for the notes.

Debt Disclosure [Abstract]

Debt

Debt In connection with the Inphi acquisition, the Company executed a debt agreement in December 2020 to obtain a $875 million 3-year term loan and a $875 million 5-year term loan. The Company also executed a debt agreement to obtain a $750 million revolving credit facility in December 2020. Below is further discussion of the terms of the various debt agreements.

2020 Term Loan Agreement

In connection with the Inphi acquisition that is expected to close in 2021, on December 7, 2020, the Company entered into a term loan credit agreement with a lending syndicate led by JP Morgan Chase Bank, N.A (the “2020 Term Loan Agreement”) in order to finance the expected merger with Inphi. The 2020 Term Loan Agreement provides for borrowings of up to $1.75 billion consisting of: (i) $875 million loan with a three-year term from the funding date (the “3-Year Tranche Loan”) and (ii) $875 million loan with a five-year term from the funding date (the “5-Year Tranche Loan” and, together with the 3-Year Tranche Loan, the "2020 Term Loans"). The availability and funding of the 2020 Term Loans is subject to satisfaction of customary conditions including the closing of the Inphi Acquisition.

The 3-Year Tranche Loan has a stated floating interest rate which equates to reserve-adjusted LIBOR + 125 bps. The 5-Year Tranche Loan has a stated floating interest rate which equates to reserve-adjusted LIBOR + 137.5 bps. The 2020 Term Loans do not require any scheduled principal payments prior to final maturity but do permit the Company to make early principal payments without premium or penalty.

The 2020 Term Loan Agreement requires that the Company and its subsidiaries comply with covenants relating to customary matters, including with respect to creating or permitting certain liens, entering into sale and leaseback transactions, and consolidating, merging, liquidating or dissolving. It also prohibits subsidiaries of the Company from incurring additional indebtedness, subject to certain exceptions, and requires that the Company maintain a leverage ratio financial covenant as of the end of any fiscal quarter. As of January 30, 2021, the Company had not yet borrowed from the 2020 Term Loans.

2020 Revolving Credit Facility

On December 7, 2020, the Company entered into a revolving line of credit agreement (“2020 Revolving Credit Facility”) with a lending syndicate led by JP Morgan Chase Bank, N.A for borrowings of up to $750 million. Borrowings from the 2020 Revolving Credit Facility are intended for general corporate use, which may include among other things, the financing of acquisitions, the refinancing of other indebtedness and the payment of transaction expenses related to the foregoing. The 2020 Revolving Credit Facility has a five-year term and a stated floating interest rate which equates to reserve-adjusted LIBOR plus an applicable margin. The Company may prepay any borrowings at any time without premium or penalty. As of January 30, 2021, the 2020 Revolving Credit Facility is undrawn and will be available for draw down through December 7, 2025. An unused commitment fee is payable quarterly based on unused balances at a rate that is based on the ratings of the Company's senior unsecured long-term indebtedness. This annual rate was 0.175% at January 30, 2021.

The 2020 Revolving Credit Facility requires that the Company and its subsidiaries comply with covenants relating to customary matters, including with respect to creating or permitting certain liens, entering into sale and leaseback transactions, and consolidating, merging, liquidating or dissolving. It also prohibits subsidiaries of the Company from incurring additional indebtedness, subject to certain exceptions, and requires that the Company maintain a leverage ratio financial covenant as of the end of any fiscal quarter.

In connection with the Cavium acquisition, the Company executed debt agreements in June 2018 to obtain a $900 million term loan, a $500 million revolving credit facility and $1.0 billion of senior unsecured notes. The $500 million revolving credit facility was replaced by the 2020 Revolving Credit Facility in December 2020.

2018 Term Loan and 2018 Revolving Credit Facility

On June 13, 2018, the Company entered into a credit agreement (“2018 Credit Agreement”) with twelve lenders. The 2018 Credit Agreement provides for borrowings of: (i) up to $500 million in the form of a revolving line of credit (the “2018 Revolving Credit Facility”) and (ii) $900 million in the form of a term loan (the “2018 Term Loan”). The proceeds of the 2018 Term Loan were used to fund a portion of the cash consideration for the Cavium acquisition, repay Cavium’s debt, and pay transaction expenses in connection with the Cavium acquisition. On December 7, 2020, the 2018 Revolving Credit Facility under the 2018 Credit Agreement was terminated and replaced by the 2020 Revolving Credit Facility.

The 2018 Term Loan has a three-year term which matures on July 6, 2021 and has a stated floating interest rate which equates to reserve-adjusted LIBOR plus a margin based on the Company's unsecured credit ratings. The effective interest rate for the 2018 Term Loan was 3.793% as of January 30, 2021. The 2018 Term Loan does not require any scheduled principal payments prior to final maturity but does permit the Company to make early principal payments without premium or penalty. During the year ended January 30, 2021 the Company repaid $250 million of the principal outstanding, and wrote off $0.7 million of associated unamortized debt issuance costs.

The 2018 Credit Agreement requires that the Company and its subsidiaries comply, subject to certain exceptions, with covenants relating to customary matters such as creating or permitting certain liens, entering into sale and leaseback transactions, and consolidating, merging, liquidating or dissolving. It also prohibits subsidiaries of the Company from incurring additional indebtedness and requires the Company to comply with a leverage ratio financial covenant as of the end of any fiscal quarter. As of January 30, 2021, the Company was in compliance with all of its debt covenants applicable to its credit agreements.

The Company currently carries debt, in the form of the 2018 Term Loan, that relies on LIBOR as the benchmark rate. LIBOR is expected to be phased out as a benchmark rate starting at the end of 2021. The 2018 Term Loan will mature before the initial phase out of LIBOR. To the extent LIBOR ceases to exist, the 2020 Term Loan and 2020 Revolving Credit Facility agreements contemplate an alternative benchmark rate without the need for any amendment thereto.

Senior Unsecured Notes

On June 22, 2018, the Company completed a public offering of (i)$500.0 million aggregate principal amount of the Company's 4.200% Senior Notes due 2023 (the “2023 Notes”) and (ii) $500.0 million aggregate principal amount of the Company's 4.875% Senior Notes due 2028 (the “2028 Notes” and, together with the 2023 Notes, the “Senior Notes”).

The 2023 Notes mature on June 22, 2023 and the 2028 Notes mature on June 22, 2028. The stated and effective interest rates for the 2023 Notes are 4.200% and 4.423%, respectively. The stated and effective interest rates for the 2028 Notes are 4.875% and 5.012%, respectively. The Company may redeem the Senior Notes, in whole or in part, at any time prior to their maturity at the redemption prices set forth in Senior Notes. In addition, upon the occurrence of a change of control repurchase event (which involves the occurrence of both a change of control and a ratings event involving the Senior Notes being rated below investment grade), the Company will be required to make an offer to repurchase the Senior Notes at a price equal to 101% of the principal amount of the notes, plus accrued and unpaid interest to, but excluding, the repurchase date. The indenture governing the Senior Notes also contains certain limited covenants restricting the Company’s ability to incur certain liens, enter into certain sale and leaseback transactions and merge or consolidate with any other entity or convey, transfer or lease all or substantially all of the Company’s properties or assets to another person, which, in each case, are subject to certain qualifications and exceptions.

Technology license obligations include the liabilities under agreements for technology licenses between the Company and various vendors.

Purchase Commitments

Under the Company’s manufacturing relationships with its foundry partners, cancellation of all outstanding purchase orders is allowed but requires payment of all costs and expenses incurred through the date of cancellation. As of January 30, 2021, these foundries had incurred approximately $329.5 million of manufacturing costs and expenses relating to the Company’s outstanding purchase orders.

Contingencies and Legal Proceedings

The Company currently is, and may from time to time become, a party to claims, lawsuits, governmental inquiries, inspections or investigations and other legal proceedings (collectively, “Legal Matters”) arising in the course of its business. Such Legal Matters, even if not meritorious, could result in the expenditure of significant financial and managerial resources.

The Company is currently unable to predict the final outcome of its pending Legal Matters and therefore cannot determine the likelihood of loss or estimate a range of possible loss, except with respect to amounts where it has determined a loss is both probable and estimable and has made an accrual. The Company evaluates, at least on a quarterly basis, developments in its Legal Matters that could affect the amount of any accrual, as well as any developments that would result in a loss contingency to become both probable and reasonably estimable. The ultimate outcome of any Legal Matter involves judgments, estimates and inherent uncertainties. An unfavorable outcome in a Legal Matter, particularly in a patent dispute, could require the Company to pay damages or could prevent the Company from selling some of its products in certain jurisdictions. While the Company cannot predict with certainty the results of the Legal Matters in which it is currently involved, the Company does not expect that the ultimate costs to resolve these Legal Matters will individually or in the aggregate have a material adverse effect on its financial condition, however, there can be no assurance that the current or any future Legal Matters will be resolved in a manner that is not adverse to the Company’s business, financial condition, results of operations or cash flows.

In the fourth quarter of fiscal 2021, the Company became involved in discussions with another party to resolve disputes that ultimately concluded with settlement by the Company in the amount of $36.0 million which was accrued at the time such offer of settlement was determined by management. Such amount is presented separately on the accompanying consolidated statement of operations for the fiscal year ended January 30, 2021.

Indemnities, Commitments and Guarantees

During its normal course of business, the Company has made certain indemnities, commitments and guarantees under which it may be required to make payments in relation to certain transactions. These indemnities may include indemnities for general commercial obligations, indemnities to various lessors in connection with facility leases for certain claims arising from such facility or lease, and indemnities to directors and officers of the Company to the maximum extent permitted under the laws of Bermuda. In addition, the Company has contractual commitments to various customers, which could require the Company to incur costs to repair an epidemic defect with respect to its products outside of the normal warranty period if such defect were to occur. The duration of these indemnities, commitments and guarantees varies, and in certain cases, is indefinite. Some of these indemnities, commitments and guarantees do not provide for any limitation of the maximum potential future payments that the Company could be obligated to make. In general, the Company does not record any liability for these indemnities, commitments and guarantees in the accompanying consolidated balance sheets as the amounts cannot be reasonably estimated and are not considered probable. The Company does, however, accrue for losses for any known contingent liability, including those that may arise from indemnification provisions, when future payment is probable and estimable.

Intellectual Property Indemnification

In addition to the above indemnities, the Company has agreed to indemnify certain customers for claims made against the Company’s products where such claims allege infringement of third-party intellectual property rights, including, but not limited to, patents, registered trademarks, and/or copyrights. Under the aforementioned indemnification clauses, the Company may be obligated to defend the customer and pay for the damages awarded against the customer as well as the attorneys’ fees and costs under an infringement claim. The Company’s indemnification obligations generally do not expire after termination or expiration of the agreement containing the indemnification obligation. Generally, there are limits on and exceptions to the Company’s potential liability for indemnification. Historically the Company has not made significant payments under these indemnification obligations and the Company cannot estimate the amount of potential future payments, if any, that it might be required to make as a result of these agreements. The maximum potential amount of any future payments that the Company could be required to make under these indemnification obligations could be significant.

In June 2019, the Company executed a funded research and development agreement with a business partner. In conjunction with the agreement, the Company issued a warrant to purchase 9.0 million of the Company's common shares, subject to certain vesting and exercise conditions.

Restricted Stock Unit Withholdings

For the years ended January 30, 2021 and February 1, 2020, the Company withheld approximately 3.1 million and 4.0 million shares, or $108.1 million and $98.3 million, of common stock, respectively, in settlement of employee tax withholding obligations due upon the vesting of restricted stock.

During fiscal 2021, the Company declared and paid cash dividends of $0.24 per common share, or $160.6 million, on the Company’s outstanding common stock. During fiscal 2020, the Company declared and paid cash dividends of $0.24 per common share, or $159.6 million, on the Company’s outstanding common stock.

Any future dividends will be subject to the approval of the Company's Board of Directors.

On March 5, 2021, the Company announced that its board of directors declared a cash dividend of $0.06 per share payable on April 28, 2021 to shareholders of record as of April 9, 2021.

Stock Repurchase Program

On November 17, 2016, the Company announced that its Board of Directors authorized a $1.0 billion share repurchase plan. The newly authorized stock repurchase program replaced in its entirety the prior $3.25 billion stock repurchase program. On October 16, 2018, the Company announced that its Board of Directors authorized a $700 million addition to the balance of its existing share repurchase plan. The Company intends to effect share repurchases in accordance with the conditions of Rule 10b-18 under the Exchange Act, but may also make repurchases in the open market outside of Rule 10b-18 or in privately negotiated transactions. The share repurchase program will be subject to market conditions and other factors, and does not obligate the Company to repurchase any dollar amount or number of its common shares and the repurchase program may be extended, modified, suspended or discontinued at any time.

The Company repurchased 1.3 million of its common shares for $25.2 million , 14.5 million of its common shares for $364.3 million and 6.0 million of its common shares for $104.0 million in cash during fiscal 2021, 2020 and 2019, respectively. The repurchased shares were retired immediately after the repurchases were completed. The Company temporarily suspended the share repurchase program in late March 2020 to preserve cash during the COVID-19 pandemic and remains temporarily suspended in anticipation of the funding of the Company's acquisition of Inphi. As a result, the Company did not repurchase any shares subsequent to the first quarter of fiscal 2021. The Company records all repurchases, as well as investment purchases and sales, based on their trade date. As of January 30, 2021, a total of 308.1 million shares have been repurchased to date under the Company’s share repurchase program for a total $4.3 billion in cash and there was $564.5 million remaining available for future share repurchases.

A summary of the stock repurchase activity under the stock repurchase program, reported based on the trade date, is summarized as follows (in thousands, except per-share amounts):

Employee Stock Compensation Plans

1995 Stock Option Plan

In April 1995, the Company adopted the 1995 Stock Option Plan (the “Option Plan”). The Option Plan, as amended from time to time, had 383.4 million common shares reserved for issuance thereunder as of January 30, 2021. Options granted under the Option Plan generally have a term of 10 years and generally must be issued at prices equal to the fair market value of the stock on the date of grant. The Company can also grant stock awards, which may be subject to vesting. Further, the Company can grant restricted stock unit (“RSU”) awards. RSU awards are denominated in shares of stock, but may be settled in cash or shares upon vesting, as determined by the Company at the time of grant. Awards under the Option Plan generally vest over 3 to 4 years.

As of January 30, 2021, approximately 77.9 million shares remained available for future grants under the Option Plan.

Equity awards granted under the Option Plan include time-based RSUs as well as RSUs that vest based on the achievement of performance-based criteria i.e. Company financial goals (“Financial Performance RSU”), or based on achievement of market-based goals i.e. relative total shareholder return (“TSR RSUs”), or stock price goals (“Value Creation Awards” or “VCA RSUs”).

Prior to fiscal year 2020, the Company granted Financial Performance RSUs to each of its executive officers when they joined the Company, and as an annual refresh grant to all executive officers and other Vice Presidents in April of each fiscal year. The Financial Performance RSUs had a three-year service requirement. The number of shares to be earned could be 0% to 200% of target and was based on the achievement of certain financial operating metrics to be measured as of the end of the second fiscal year of the three-year vesting term. Shares granted under these Financial Performance RSUs are reported in the table presented below as “Performance-Based” based on 100% expected achievement.

In addition, the Company grants TSR RSUs to its executive officers that newly join the Company, and as an annual refresh grant to all executive officers and other Vice Presidents, usually in April of each fiscal year. Prior to fiscal year 2020, TSR RSUs were measured based on stock performance as compared to that of companies on the Philadelphia Semiconductor Sector over a performance period defined in the award. The number of shares to be earned can be 0% to 150% of target and is based on the achievement of performance objectives relating to relative total shareholder return of the Company’s common shares. Beginning in fiscal year 2020, the S&P 500 Index serves as the benchmark index. The TSR RSUs have a three year service vesting requirement. The number of shares to be earned can be 0% to 200% of target and is based on the achievement of performance objectives relating to relative total shareholder return of the Company's common shares. These TSR RSUs are reported in the table presented below as “Market-Based” awards based on 100% expected achievement.

In fiscal year 2020, the Company issued Value Creation Awards that are based on achievement of the Company's stock price target over a specified performance period, also referred to as VCA RSUs. The VCA RSU will be earned if the Company's average closing trading stock price over 100-calendar days equals or exceeds a certain target price. 100% of the award will vest on the 1-year anniversary of the achievement. The grant will be forfeited if the market-based condition is not achieved. These VCA RSUs are reported in the table presented below as “Market-Based” awards based on 100% expected achievement. As of January 30, 2021, the performance metrics have been achieved. The awards will vest on the 1-year anniversary of the achievement in November 2021.

In December 2017, the Company’s Executive Compensation Committee approved a deferred stock program, whereby executives of the Company have the option, beginning in 2018, to defer the settlement of time-based and performance-based restricted stock units granted under the Option Plan to a future date. A deferral election is irrevocable after the annual submission deadline. The shares of common stock underlying the deferred grants will be distributed at the earliest of the employee’s specified future settlement date, not to be earlier than 2023, or upon separation from service, a change in control, or death or disability. As of January 30, 2021, no grants have been subject to a deferral election.

Awards expire seven to ten years from the date of grant.

QLogic 2005 Plan

The QLogic 2005 Plan was assumed and registered by Cavium upon its completion of acquisition of QLogic Corporation on August 16, 2016. The QLogic 2005 Plan provided for the issuance of restricted stock unit awards, incentive and non-qualified stock options, and other stock-based incentive awards. Restricted stock unit awards granted pursuant to the QLogic 2005 Plan to employees subject to a service condition generally vest over four years from the date of grant.

Outside Director Equity Compensation Policy

In September 2016, the Company’s Board of Directors approved the termination of the 2007 Directors’ Stock Incentive Plan, (“2007 Director Plan”) that was initially adopted in October 2007, and it approved a new Outside Director Equity Compensation Policy that governs the grant of equity awards to non-employee directors under the Option Plan. At the annual general meeting of shareholders held in June 2015, the shareholders approved an amendment to the Option Plan to enable a full range of awards to be granted to non-employee directors. Under the newly amended Outside Director Compensation Policy, each outside director, upon appointment to fill a vacancy on the board or in connection with election at an annual meeting of shareholders, will be granted an RSU award under the Option Plan for a number of shares with an aggregate fair market value equal to $235,000 on the grant date. In no event shall an outside director be awarded an annual RSU award for more than 20,000 shares. The RSU award vests 100% on the earlier of the date of the next annual general meeting of shareholders or the one-year anniversary of the date of grant.

Employee Stock Purchase Plan

Under the 2000 Employee Stock Purchase Plan, as amended and restated on October 31, 2011 (the “ESPP”), participants purchase the Company’s stock using payroll deductions, which may not exceed 15% of their total cash compensation. Pursuant to the terms of the current ESPP, the “look-back” period for the stock purchase price is 24 months. Offering and purchase periods begin on December 8 and June 8 of each year. Participants enrolled in a 24-month offering period will continue in that offering period until the earlier of the end of the offering period or the reset of the offering period. A reset occurs if the fair market value of the Company’s common shares on any purchase date is less than it was on the first day of the offering period. Participants in a 24-month offering period will be granted the right to purchase common shares at a price per share that is 85% of the lesser of the fair market value of the shares at (i) the participant’s entry date into the two-year offering period or (ii) the end of each six-month purchase period within the offering period.

Under the ESPP, a total of 5.0 million shares were issued in fiscal 2021 at a weighted-average price of $14.36 per share, a total of 5.2 million shares were issued in fiscal 2020 at a weighted-average price of $13.25 per share, and a total of 3.2 million shares were issued in fiscal 2019 at a weighted-average price of $15.08 per share. As of January 30, 2021, there was $55.9 million of unamortized compensation cost related to the ESPP.

As of January 30, 2021, approximately 32.5 million shares remained available for future issuance under the ESPP.

Valuation of Employee Share-Based Awards

The expected volatility for awards granted during fiscal 2021, 2020 and 2019 was based on historical stock price volatility.

The expected dividend yield is calculated by dividing the current annualized dividend by the closing stock price on the date of grant of the option.

There were no options granted in fiscal 2021, 2020 and 2019 except for the ones the Company assumed from the Cavium and Aquantia acquisitions as described above.

The income tax benefit for fiscal 2021 is primarily attributable to the pretax losses of the Company’s subsidiaries with income tax rates that differ from the U.S. statutory tax rate, combined with a net reduction of unrecognized tax benefits inclusive of interest and penalties, offset by tax expense attributable to non-deductible compensation. The income tax benefit for fiscal 2020 was primarily the result of the recognition of a $763.0 million tax benefit for the intra-entity transfer of the majority of the Company’s intellectual property to a subsidiary in Singapore. This resulted in the recognition of a deferred tax asset and tax benefit of $659.0 million related to the Singapore tax basis in the intellectual property. In addition, the Company recognized $104.0 million of income tax benefit from the reversal of deferred tax liabilities primarily related to previously acquired intangible assets. The income tax expense for fiscal 2019 was primarily the result of restructurings involving the transfer of certain assets and intellectual property used in the business among various subsidiaries and represented the estimated U.S. tax to be paid currently and in future years on income generated from the intellectual property transfer. The prior period transactions aligned the global economic ownership of the Company's intellectual property rights with its current and future business operations. The Company continues to evaluate potential changes to its legal entity structure in response to guidelines and requirements in various international tax jurisdictions, as well as in response to changes in our operations, and acquisitions and divestitures.

The deferred tax assets and liabilities based on tax jurisdictions are presented on our consolidated balance sheet as follows:


	January 30, 2021		February 1, 2020
Non-current deferred tax assets	$	672,424	$	639,791
Non-current deferred tax liabilities	(22,359)		(31,233)
Net deferred tax assets (liabilities)	$	650,065	$	608,558

In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred assets will be realized. The ultimate realization of the deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible or creditable. The Company weighs all positive and negative evidence including our earnings history, results of recent operations, reversals of deferred tax liabilities, projected future taxable income, and tax planning strategies. As of January 30, 2021, the Company recorded a valuation allowance of $749.5 million which is an increase of $72.7 million from fiscal 2020. The Company provided a full valuation allowance against its federal and state research and development and other tax credits. Based on the available objectively verifiable positive and negative evidence, the Company determined that it is more likely than not that these tax credits and a limited amount of net operating losses will not be realized in the future. The Company also provided a valuation allowance against the deferred tax assets of a portion of its operations in Israel, which has cumulative losses in recent years and is not projecting sufficient future taxable income to realize the benefit of its deferred tax assets, as well as a valuation allowance against Canadian research and development credits. It is also possible that significant negative evidence may become available that causes the Company to conclude that a valuation allowance is needed on certain of its other deferred tax assets, which would adversely affect the Company's income tax provision in the period of such change in judgment.

As of January 30, 2021, the Company had net operating loss carryforwards available to offset future taxable income of approximately $832.6 million, $517.3 million and $815.1 million for U.S. federal, state of California and foreign purposes, respectively. The federal carryforwards will begin to expire in fiscal year 2022, and the California carryforwards will begin to expire in fiscal year 2028, if not utilized before these years. The majority of the Company’s foreign losses carry forward indefinitely. The Company also had federal research and other tax credit carryforwards of approximately $360.3 million which will begin to expire in fiscal 2022. As of January 30, 2021, the Company also had California research tax credit carryforwards of approximately $478.6 million, which can be carried forward indefinitely. The Company also has research and other tax credit carryforwards of approximately $28.8 million in other U.S. states which will begin to expire in fiscal 2022 due to the statutes of limitation.

Utilization of the Company's U.S. federal and state net operating loss and credit carryforwards may be subject to annual limitations due to ownership change provisions by the Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitation may result in the expiration of net operating losses and credits before utilization. Future changes in the Company's stock ownership, some of which are outside of the Company's control, could result in an ownership change under Section 382 and result in a limitation on US tax attributes. As of January 30, 2021, the Company had approximately $801.1 million and $120.4 million of federal net operating loss and tax credit carryforwards, respectively, in the U.S. subject to an annual limitation. The Company does not expect these limitations to result in any permanent loss of its tax benefits.

The following table reflects changes in the unrecognized tax benefits (in thousands):


	Year Ended
	January 30, 2021		February 1, 2020		February 2, 2019

Gross amounts of unrecognized tax benefits as of the end of the period	$	242,150	$	166,828	$	158,323

Included in the balances as of January 30, 2021 is $171.5 million of unrecognized tax benefit that would affect the effective income tax rate if recognized. Also, in the year ended January 30, 2021, the Company increased its uncertain prior year tax positions by $77.9 million which included $75.1 million related to items that had been previously accrued as deferred tax liabilities and are now reflected as reductions to deferred tax assets at January 30, 2021, as a result of a current year change in the Company's assessment of its future income tax filing positions for these items. Finally, $221.7 million, $146.6 million and $135.6 million of the gross unrecognized tax benefits presented in the table above are offset against deferred tax assets in the consolidated balance sheets as of January 30, 2021, February 1, 2020 and February 2, 2019, respectively.

The amounts in the table above do not include the related interest and penalties. The amount of interest and penalties accrued was approximately $4.0 million, $12.4 million, and $15.1 million as of January 30, 2021, February 1, 2020, and February 2, 2019, respectively. The Company’s policy is to recognize these interest and penalties as a component of income tax expense. The consolidated statements of operations for fiscal 2021, 2020, and 2019 included $1.0 million, $1.4 million, and $2.7 million, respectively, of interest and penalties related to the unrecognized tax benefits.

The Company's major tax jurisdictions are the United States, the states of California and Massachusetts, China, India, Israel, and Singapore. The Company is subject to income tax audits by the respective tax authorities in all of the jurisdictions in which it operates. The examination of tax liabilities in each of these jurisdictions requires the interpretation and application of complex and sometimes uncertain tax laws and regulations. As of January 30, 2021, the Company is subject to examination in material jurisdictions including China, India, Israel, Singapore, Germany, and the United States for fiscal years 2001 through 2021.

The Company will continue to review its tax positions and provide for or reverse unrecognized tax benefits as issues arise. During the next 12 months, it is reasonably possible that the amount of unrecognized tax benefits could increase or decrease significantly due to changes in tax law in various jurisdictions, new tax audits and changes in the U.S. dollar as compared to foreign currencies within the next 12 months. Excluding these factors, uncertain tax positions may decrease by $5.4 million from the lapse of the statutes of limitation in various jurisdictions during the next 12 months.

The Singapore Economic Development Board (“EDB”) initially granted a 10-year Pioneer Status in July 1999 to the Company’s Singapore subsidiary. In October 2004, the Company’s subsidiary in Singapore was granted a second incentive known as the Development and Expansion Incentive (“DEI”), and in June 2006, the EDB agreed to extend the Pioneer status for 15 years to June 2014. The Company renegotiated with the Singapore government and in fiscal 2015, they extended the DEI tax incentives to the Company until June 2019. The Company renegotiated again with the Singapore government and during the second quarter of fiscal 2020, they extended the DEI tax incentives until June 2024. In the future, the Company may negotiate a further extension of these incentives. In order to retain these tax benefits in Singapore, the Company must meet certain operating conditions relating to, among other things, certain headcount and investment requirements, as well as maintenance of a regional headquarters function, and certain research and development activities in Singapore. There was no such benefit in fiscal 2021, 2020, and 2019.

Under the Israeli Encouragement law of “approved or benefited enterprise,” Marvell Israel (M.I.S.L) Ltd., is entitled to approved and benefited tax programs that include reduced tax rates and exemption of certain income with respect to its Galileo switches activity, subject to various operating and other conditions. Income from the approved or benefited enterprises, with the exception of capital gains, is eligible up to fiscal 2027. In fiscal 2021, tax savings associated with these tax holidays were approximately $2.1 million, which if paid would impact the Company’s earnings per share by less than $0.01 per share in fiscal 2021. There was no such benefit recognized in fiscal 2020 or fiscal 2019.

The Coronavirus Aid, Relief, and Economic Security (“CARES”) Act was enacted into US federal law on March 27, 2020. The CARES Act provided numerous tax provisions and other stimulus measures, including temporary changes regarding the prior and future utilization of net operating losses, temporary changes to the prior and future limitations on interest deductions, and technical corrections from prior tax legislation for tax depreciation of certain qualified improvement property. The Company evaluated the provisions of the CARES Act and concluded that there was no material impact on its financial statements. The tax effects of other related foreign government assistance enacted into law this period are also not material to the Company this period.

The Company’s principal source of liquidity as of January 30, 2021 consisted of approximately $748.5 million of cash and cash equivalents, of which approximately $618.1 million was held by subsidiaries outside of Bermuda. The Company has not recognized a deferred tax liability on $264.2 million of these assets as those amounts are deemed to be indefinitely reinvested. The Company plans to use such amounts to fund various activities outside of Bermuda, including working capital requirements, capital expenditures for expansion, funding of future acquisitions or other financing activities.

Net Income (Loss) Per Share

The Company reports both basic net income (loss) per share, which is based on the weighted-average number of common shares outstanding during the period, and diluted net income (loss) per share, which is based on the weighted-average number of common shares outstanding and potentially dilutive shares outstanding during the period. The computations of basic and diluted net income (loss) per share are presented in the following table (in thousands, except per share amounts):

Potential dilutive securities include dilutive common shares from share-based awards attributable to the assumed exercise of stock options, restricted stock units and employee stock purchase plan shares using the treasury stock method. Under the treasury stock method, potential common shares outstanding are not included in the computation of diluted net income per share, if their effect is anti-dilutive.

Anti-dilutive potential shares are presented in the following table (in thousands):

Anti-dilutive potential shares from share-based awards are excluded from the calculation of diluted earnings per share for all periods reported above because either their exercise price exceeded the average market price during the period or the share-based awards were determined to be anti-dilutive based on applying the treasury stock method. Anti-dilutive potential shares from share-based awards are also excluded from the calculation of diluted earnings per share for the years ended January 30, 2021 and February 2, 2019 due to the net losses reported in those periods.

Segment Reporting [Abstract]

Segment and Geographic Information

The Company operates in one reportable segment — the design, development and sale of integrated circuits. The chief executive officer was identified as the chief operating decision maker (“CODM”) and is ultimately responsible for and actively involved in the allocation of resources and the assessment of the Company’s performance. The fact that the Company operates in only one reportable segment is based on the following:

•The Company uses a highly-integrated approach in developing its products in that discrete technologies developed by the Company are frequently integrated across many of its products. Substantially all of the Company’s integrated circuits are manufactured under similar manufacturing processes.

•The Company’s organizational structure is based along functional lines. Each of the functional department heads reports directly to the CODM. Shared resources in the Company also report directly to the CODM or to a direct report of the CODM.

•The assessments of performance across the Company, including assessment of the Company’s incentive compensation plan, are based largely on operational performance and consolidated financial performance.

•The decisions on allocation of resources and other operational decisions are made by the CODM based on his direct involvement with the Company’s operations and product development.

Leases The Company determines if an arrangement is a lease at inception. Operating lease right-of-use (“ROU”) assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Operating lease ROU assets also include any initial direct costs and prepayments less lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options. As the Company's leases do not provide an implicit rate, the Company uses its collateralized incremental borrowing rate based on the information available at the lease commencement date, including lease term, in determining the present value of lease payments. Lease expense for these leases is recognized on a straight line basis over the lease term.

- Definition

Total of all stockholders' equity (deficit) items, net of receivables from officers, directors, owners, and affiliates of the entity which are attributable to the parent. The amount of the economic entity's stockholders' equity attributable to the parent excludes the amount of stockholders' equity which is allocable to that ownership interest in subsidiary equity which is not attributable to the parent (noncontrolling interest, minority interest). This excludes temporary equity and is sometimes called permanent equity.
