Note 2. Recent Accounting Pronouncements

Accounting Pronouncements Recently Adopted

In May 2014, the FASB issued a new accounting standard on the recognition of revenue from contracts with customers that superseded nearly all existing revenue recognition guidance under GAAP. The new standard requires an entity to recognize revenue from the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance addresses, in particular, contracts with more than one performance obligation, as well as the accounting for certain costs to obtain or fulfill a contract with a customer, and provides for additional disclosures with respect to revenue and cash flows arising from contracts with customers. Public entities are required to apply the amendments on either a full or modified retrospective basis for annual periods beginning after December 15, 2017 and for interim periods within those annual periods. The Company adopted the standard on a modified retrospective basis in the first quarter of fiscal year 2019, with the cumulative effect recognized in retained earnings at the date of adoption. See "Note 5 - Revenue" for additional information on the impact of the adoption of the new standard on the Company’s consolidated financial statements.

In January 2016, the FASB issued an accounting standard update that changes the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. The Company adopted the standard in the first quarter of fiscal 2019. The adoption of this guidance did not have a significant impact on the Company's consolidated financial statements.

In August 2016, the FASB issued an accounting standards update to add or clarify guidance on the classification of certain cash receipts and cash payments in the statement of cash flows. The amendments in the update provide guidance on eight specific cash flow issues. The amendments to the guidance should be applied using a retrospective transition method for each period presented and, if it is impracticable to apply all of the amendments retrospectively for some of the issues, the amendments for those issues would be applied prospectively as of the earliest date practicable. The Company adopted the standard in the first quarter of fiscal 2019. The adoption of this guidance did not have an impact on the Company's consolidated financial statements.

In October 2016, the FASB issued new guidance that simplifies the accounting for the income tax effects of intra-entity transfers and will require companies to recognize the income tax effects of intra-entity transfers of assets other than inventory when the transfer occurs. Previous guidance required companies to defer the income tax effects of intra-entity transfers of assets until the asset had been sold to an outside party or otherwise recognized. The Company adopted the standard in the first quarter of fiscal 2019. The adoption of this guidance did not have an impact on the Company's consolidated financial statements.

In November 2016, the FASB issued new guidance that requires entities to include in their cash and cash-equivalent balances in the statement of cash flows those amounts that are deemed to be restricted cash and restricted cash equivalents. As a result, companies will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. The Company adopted the standard in the first quarter of fiscal 2019. The adoption of this guidance did not have a significant impact on the Company's consolidated financial statements.

In January 2017, the FASB issued an accounting standards update that revises the definition of a business. The amendments provide a more robust framework for determining when a set of assets and activities is a business. The update is intended to help companies evaluate whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The Company adopted the standard in the first quarter of fiscal 2019. The adoption of this guidance did not have an impact on the Company's consolidated financial statements.

In May 2017, the FASB issued an accounting standards update that provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. Unless the changes in terms or conditions meet all three criteria outlined in the guidance, modification accounting should be applied. The three criteria relate to changes in the terms and conditions that affect the fair value, vesting conditions, or classification of a share-based payment award. The guidance is required to be applied prospectively to an award modified on or after the adoption date. The Company adopted the standard in the first quarter of fiscal 2019. The adoption of this guidance did not have an impact on the Company's consolidated financial statements.

In June 2018, the Financial Accounting Standards Board (“FASB”) issued an accounting standards update that substantially aligns the accounting for shared-based payments to non-employees and employees. The standard is required to be applied through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. Early adoption is permitted. The Company early adopted the standard in the second quarter of fiscal 2019. The adoption of this guidance did not have a significant impact on the Company's consolidated financial statements.

Accounting Pronouncements Not Yet Effective

In February 2016, the FASB issued a new standard on the accounting for leases, which requires a lessee to record a right-of-use asset and a corresponding lease liability on the balance sheet for all leases with terms longer than twelve months. The standard also expands the required quantitative and qualitative disclosures for lease arrangements. The standard is effective for the Company beginning in the first quarter of fiscal year 2020. The Company is currently evaluating the effect this new guidance will have on its consolidated financial statements.

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 standard is effective for the Company beginning in the first quarter of fiscal year 2020. The Company does not expect the adoption of this guidance will have a material effect on its consolidated financial statements.

In August 2017, the FASB issued an accounting standards update that simplifies the application and administration of hedge accounting. The guidance amends the presentation and disclosure requirements and changes how companies assess effectiveness. The guidance is intended to more closely align hedge accounting with companies' risk management strategies, simplify the application of hedge accounting, and increase transparency as to the scope and results of hedging programs. The guidance is effective for the Company beginning in the first quarter of fiscal year 2021. Early adoption is permitted. The guidance will be applied to cash flow and net investment hedge relationships that exist on the date of adoption using a modified retrospective approach. The presentation and disclosure requirements will be applied prospectively. The Company is evaluating the effect this new guidance will have on its consolidated financial statements.

In August 2018, the FASB issued an accounting standard 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 guidance is effective for the Company beginning in the first quarter of fiscal year 2021, with early adoption permitted. The Company is evaluating the effect this new guidance will have on its consolidated financial statements.

Note 3. Business Combination

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 4 - Debt” for discussion of the debt financing.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS ‑ (Continued)

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

Pursuant to the Cavium merger agreement, the Company assumed the outstanding employee equity awards originally granted by Cavium and converted such shares into the Company’s equivalent awards. The outstanding vested options held by directors of Cavium were settled in cash as specified in the Cavium merger agreement. The portion of the fair value of partially vested awards associated with pre-acquisition service of Cavium employees represented a component of the total consideration, as presented above.

The merger consideration allocation set forth herein is preliminary and may be revised as additional information becomes available during the measurement period which could be up to 12 months from the closing date of the acquisition. Any such revisions or changes may be material.

In accordance with US GAAP requirements for business combinations, the Company allocated the fair value of the purchase consideration to the tangible assets, liabilities and intangible assets acquired, including in-process research and development, or IPR&D, generally based on their estimated fair values. The excess purchase price over those fair values is recorded as goodwill. Goodwill of $3.5 billion recorded for the Cavium acquisition is not expected to be deductible for tax purposes. 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.  The Company’s valuation assumptions of acquired assets and assumed liabilities require significant estimates, especially with respect to intangible assets. Acquisition-related costs are expensed in the periods in which the costs are incurred.

MARVELL TECHNOLOGY GROUP LTD.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS ‑ (Continued)

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

    

The valuation of identifiable intangible assets and their estimated useful lives are as follows:

The intangible assets are amortized on a straight-line basis over the estimated useful lives, except for customer contracts and related relationships, which are amortized using an accelerated method of amortization over the expected customer lives, which more accurately reflects 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 or are abandoned 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 4 to 9 years .

During the three and six months ended August 4, 2018, the Company incurred $28.2 million and $43.5 million , respectively, in acquisition related costs which were recorded in selling, general and administrative expense in the condensed consolidated statements of operations.  The Company also incurred $22.8 million of debt financing costs. As of August 4, 2018, $0.4 million associated with the Revolving Credit Facility was classified in prepaid expenses and other current assets, $1.5 million associated with the Revolving Credit Facility was classified in other non-current assets, and $14.1 million associated with the term loan and senior notes was classified in long-term debt in the condensed consolidated balance sheet. See “Note 4. Debt” for additional information. Additionally, the Company incurred $2.9 million of equity issuance costs, which were recorded in additional paid-in capital in the condensed consolidated balance sheet.

Since the date of the acquisition, Cavium contributed $41.3 million  of the consolidated net revenue for the three and six months ended August 4, 2018. Cavium net loss incurred in the period ended August 4, 2018 was $120.6 million , which included restructuring costs of $22.3 million .

Note 4. Debt

On July 6, 2018, the Company completed its acquisition of Cavium. In connection with the acquisition (see "Note 3 - Business Combination"), 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. Upon completion of the offering of the senior unsecured notes in June 2018, the Company terminated an $850 million bridge loan commitment. This bridge loan commitment was provided by the underwriting bankers at the time of the Merger Agreement executed in November 2017. The bridge loan was never drawn upon.

Term Loan and Revolving Credit Facility

On June 13, 2018, the Company entered into a credit agreement (“Credit Agreement”) with certain lenders and Goldman Sachs Bank USA, as the general administrative agent and the term facility agent, and Bank of America, N.A., as the revolving facility agent. The Credit Agreement provides for borrowings of: (i) up to $500.0 million in the form of a revolving line of credit (“Revolving Credit Facility”) and (ii)  $900.0 million in the form of a term loan (“Term Loan”). The proceeds of the 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. The proceeds of the Revolving Credit Facility is intended for general corporate purposes of the Company and its subsidiaries, 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. As of August 4, 2018, the Revolving Credit Facility has not been drawn upon. Following is further detail of the terms of the various debt agreements.

The Term Loan has a three year term which matures on June 13, 2021 and has a stated floating interest rate which equates to reserve-adjusted LIBOR + 137.5 bps as of August 4, 2018. The effective interest rate for the Term Loan was 3.912% as of August 4, 2018. As of August 4, 2018, the entire principal balance of $900.0 million Term Loan was outstanding. The Term Loan does not require any scheduled principal payments prior to final maturity. The Revolving Credit Facility has a five year term and has a stated floating interest rate which equates to reserve-adjusted LIBOR + 150.0 bps. As of August 4, 2018, the full amount of the Revolving Credit Facility of $500 million was undrawn and will be available for draw down through June 13, 2023. 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 rate was initially 0.175% per year.

The 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, consolidating, merging, liquidating or dissolving, and entering into restrictive agreements. It also prohibits subsidiaries of the Company from incurring additional indebtedness, and requires the Company to comply with a leverage ratio financial covenant not to exceed 3 to 1 as of the end of any fiscal quarter. As of August 4, 2018, the Company was in compliance with all of its debt covenants.

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.

Note 5. Revenue

Effect of the Adoption of the New Revenue Standard

At the beginning of fiscal year 2019, the Company adopted the new revenue recognition standard on a modified retrospective basis, with the cumulative effect recognized in retained earnings at the date of adoption. The Company elected to apply the new revenue standard retrospectively to all contracts that are not completed contracts at the date of the initial adoption. Based on the Company’s assessment of this new accounting standard, a change in revenue recognition timing on its component sales made to distributors was made in the first quarter of fiscal year 2019 and the Company started to recognize revenue when the Company transfers control to the distributor rather than deferring recognition until the distributor sells the components. In addition, the Company established accruals for the variable consideration aspect of sales, estimated based on historical experience, which include estimates for price discounts, price protection, rebates, returns and stock rotation programs. On the date of initial adoption, the Company removed the deferred income on component sales made to distributors and recorded estimates of the accruals for variable consideration through a cumulative adjustment to retained earnings. The net impact to the opening balance of retained earnings related to the adoption of the new standard was an increase of $34.2 million .

The following table summarizes the effects of adopting the new revenue standard on the Company's financial statements for the fiscal year beginning February 4, 2018 as an adjustment to the opening balance. Such adjustments were of a non-cash nature.

MARVELL TECHNOLOGY GROUP LTD.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS ‑ (Continued)

Adoption of the new revenue standard had no impact to cash from or used in operating, financing, or investing activities on the condensed consolidated statements of cash flow.

New Revenue Recognition Policy Including Significant Judgments and Estimates

Through the fiscal year ended February 3, 2018, in accordance with ASC 605, Revenue Recognition, the Company recognized revenue when there was persuasive evidence of an arrangement, delivery had occurred, the fee was fixed or determinable, and collection was reasonably assured. If the Company granted extended payment terms greater than its standard terms for a customer such that collectability was not assured, the revenue was deferred upon shipment and would be recognized when the payment became due provided all other revenue recognition criteria had been satisfied.

Product revenue was generally recognized upon shipment of product to customers, net of accruals for estimated sales returns and rebates. However, some of the Company’s sales were made through distributors under agreements allowing for price protection and limited rights of stock rotation on products unsold by the distributors. Product revenue on sales made through distributors were deferred until the distributors sold the product to end customers. Deferred revenue less the related cost of the inventories was reported as deferred income. The Company did not believe that there was any significant exposure related to impairment of deferred cost of sales, as its historical returns had been minimal and inventory turnover for its distributors generally ranged from 60 to 90 days . The Company’s sales to direct customers were made primarily pursuant to standard purchase orders for delivery of products.

As a result of the adoption of the new revenue standard on February 4, 2018, at the beginning of the first quarter of fiscal year 2019, the Company revised its revenue recognition policy. The Company now recognizes revenue upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. Under the new revenue recognition standard, the Company applies the following five step approach: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when a performance obligation is satisfied.

The Company enters into contracts that may include various combinations of products and services that are capable of being distinct and accounted for as separate performance obligations. To date, the majority of the revenue has been generated by sales associated with storage and networking products. Revenue from services has been insignificant. Performance obligations associated with product sales transactions are generally satisfied when control passes to customers upon shipment. Accordingly, product revenue is recognized at a point in time when control of the asset is transferred to the customer. 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 of credit memo data and other known factors. Actual returns could differ from these estimates. 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. Some of the Company’s sales are made to distributors under agreements allowing for price protection, price discounts and limited rights of stock rotation on products unsold by the distributors. Control passes to the distributor upon shipment, and terms and payment by the Company’s distributors is not contingent on resale of the product. Product revenue on sales made to distributors with price protection 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.

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.

Disaggregation of Revenue

The majority of the Company's revenue is generated from sales of the Company’s products.

The following table summarizes net revenue disaggregated by primary geographical market (in thousands, except percentages):

The following table summarizes net revenue disaggregated by customer type (in thousands, except percentages):

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 August 4, 2018, 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 condensed consolidated balance sheets.

The opening balance of contract liabilities at the beginning of the first quarter of fiscal year 2019 was $79.6 million . During the six months ended August 4, 2018, contract liabilities increased by $363.3 million associated with variable consideration estimates for additional shipments in the quarter, offset by $336.7 million decrease in such reserves primarily due to credit memos issued to customers. The ending balance of contract liabilities as of the second quarter ended in fiscal year 2019 was $106.2 million .

Sales Commissions

Sales commissions are generally earned by the salespersons based on shipments to customers. The Company has elected to apply the practical expedient to expense these costs when incurred as the amortization period is typically one year or less. These costs are recorded in selling, general and administrative expenses in the condensed consolidated statements of operations.

Note 6. 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 August 4, 2018 and February 3, 2018 is $5.5 billion and $2.0 billion , respectively. The change in the carrying value of goodwill from February 3, 2018 to August 4, 2018 was due to the Cavium acquisition. See “Note 3 - Business Combination” for further discussion of the acquisition.

Acquired Intangible Assets, Net

There had been no new acquired intangible assets in fiscal year 2018, and as of February 3, 2018, the gross value of acquired intangible assets was fully amortized. In connection with the Cavium acquisition on July 6, 2018, the Company acquired $2.7 billion of intangible assets. As of the second quarter ended August 4, 2018, net carrying amounts are as follows (in thousands, except for weighted average remaining amortization period):
