The Company and Basis of Presentation

The Company and Basis of Presentation

Note 1. The Company and Basis of Presentation

The Company

Marvell Technology Group Ltd., a Bermuda company (the “Company”), is a leading global semiconductor provider of high performance application specific standard products. The Company’s core strength of expertise 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 ARM-based microprocessor integrated circuits. The Company also develops platforms that it defines as integrated hardware and software that incorporate digital computing technologies designed and configured to provide an optimal computing solution compared to individual components. The Company’s broad product portfolio includes devices for data storage, enterprise-class Ethernet data switching, Ethernet physical-layer transceivers, handheld cellular, Ethernet-based wireless networking, personal area networking, Ethernet-based PC connectivity, control plane communications controllers, video-image processing and power management solutions.

Reclassification

Certain amounts in the unaudited condensed consolidated financial statements and notes to the unaudited condensed consolidated financial statements for prior years have been reclassified to conform to the fiscal 2013 presentation. Net operating results have not been affected by these reclassifications.

Basis of Presentation

The Company’s fiscal year is the 52- or 53-week period ending on the Saturday closest to January 31. In a 52-week year, each fiscal quarter consists of 13 weeks. The additional week in a 53-week year is added to the fourth quarter, making such quarter consist of 14 weeks. Fiscal 2013 has a 53-week period and therefore, the fourth quarter which ends on February 2, 2013 includes 14 weeks. Fiscal 2012 had a 52-week period.

The unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for annual financial statements. In the opinion of management, all adjustments consisting of normal and recurring entries considered necessary for a fair statement of the results for the interim periods have been included in the Company’s balance sheet as of October 27, 2012, the results of its operations for the three and nine months ended October 27, 2012 and October 29, 2011, and its cash flows for the nine months ended October 27, 2012 and October 29, 2011. The January 28, 2012 condensed consolidated balance sheet data was derived from the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended January 28, 2012 but does not include all disclosures required for annual periods.

These condensed consolidated financial statements and related notes are unaudited and should be read in conjunction with the Company’s audited financial statements and related notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended January 28, 2012 as filed on March 27, 2012 with the Securities and Exchange Commission. The results of operations for the three and nine months ended October 27, 2012 are not necessarily indicative of the results that may be expected for any other interim period or for the full fiscal year.

Use of Estimates

The preparation of consolidated financial statements in conformity with 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 assets and liabilities. On an on-going 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, income taxes, litigation and other contingencies. In addition, the Company uses assumptions when employing the Monte Carlo simulation and Black-Scholes valuation models to calculate the fair value of share-based awards that are granted. When carrying values of certain assets and liabilities are not readily available from other sources, their carrying values are estimated based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from these estimates, and such differences could affect the results of operations reported in future periods.

Principles of Consolidation

The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated. The functional currency of the Company and its subsidiaries is the United States dollar.

Recent Accounting Pronouncements

Note 2. Recent Accounting Pronouncements

Accounting Pronouncements Recently Adopted

The Company adopted the new accounting standard that provides additional guidance on fair value measurements and related disclosures at the beginning of fiscal 2013. This guidance clarifies the application of existing guidance on fair value measurement for non-financial assets and requires the disclosure of quantitative information about the unobservable inputs used in a fair value measurement. The adoption of this guidance had no impact on the Company’s financial statements.

The Company also adopted the new accounting standard that permits an entity the option to present the total of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements at the beginning of fiscal 2013. This amended guidance eliminates the option to present the components of other comprehensive income as part of the statement of changes in shareholders’ equity. As a result, the Company has separately presented the Statements of Comprehensive Income as part of its unaudited condensed consolidated financial statements.

The Company also adopted the new accounting standard that amends the previous guidance regarding the testing of goodwill for impairment at the beginning of fiscal 2013. This amended guidance allows an entity to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. An entity no longer is required to calculate the fair value of a reporting unit unless the entity determines, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. The adoption of this guidance had no impact on the Company’s financial statements.

Accounting Pronouncements Not Yet Effective

In July 2012, the Financial Accounting Standards Board issued an amendment to its guidance regarding the testing of indefinite-lived intangible assets for impairment. This amended guidance allows an entity first to assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test in accordance with the guidance on the impairment of intangible assets other than goodwill. This amended guidance is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. The adoption of this guidance is not expected to have an impact on the Company’s financial statements.

- Definition

The entire disclosure of changes in accounting principles, including adoption of new accounting pronouncements, that describes the new methods, amount and effects on financial statement line items.

As of October 27, 2012, the Company’s investment portfolio included auction rate securities with an aggregate par value of $19.5 million. To estimate the fair value of the auction rate securities, the Company uses a discounted cash flow model based on estimated timing and amount of future interest and principal payments. In developing the cash flow model, the Company considers the credit quality and liquidity of the underlying securities and related issuer, the collateralization of underlying security investments and other considerations. The fair value of the auction rate securities as of October 27, 2012 was $1.4 million less than the par value and was recorded in long-term investments. Based on the Company’s balance of approximately $2.0 billion in cash, cash equivalents and short-term investments, and the fact that the Company continues to generate positive cash flow from operations on a quarterly basis, the Company does not anticipate having to sell these securities below par value and does not have the intent to sell these auction rate securities until recovery. Since the Company considers the impairment to be temporary, the Company recorded the unrealized loss to accumulated other comprehensive income, a component of shareholders’ equity.

The contractual maturities of available-for-sale securities are presented in the following table (in thousands):


	October 27, 2012				January 28, 2012

Anti-dilutive potential common shares for stock options are excluded from the calculation of diluted earnings per share for the periods reported above because their exercise price exceeded the average market price during the period. The anti-dilutive shares reported above also include shares from stock options that contain market conditions for vesting since the market value of the Company’s stock as of October 27, 2012 and October 29, 2011 was lower than the required market condition. For the three and nine months ended October 27, 2012, there were 3.0 million and 3.1 million anti-dilutive shares, respectively, from stock options that contain market conditions. For the corresponding three and nine months ended October 29, 2011, there were 3.1 million and 2.1 million anti-dilutive shares, respectively, from stock options that contain market conditions. See Note 11 – “Share-Based Compensation” for additional details.

Derivative Financial Instruments

Note 5. Derivative Financial Instruments

The Company manages some of its foreign currency exchange rate risk through the purchase of foreign currency exchange contracts that hedge against the short-term effect of currency fluctuations. The Company’s policy is to enter into foreign currency forward contracts with maturities generally less than 12 months that mitigate the effect of rate fluctuations on certain local currency denominated operating expenses. All derivative instruments are recorded at fair value in either prepaid expenses and other current assets or accrued liabilities. The Company reports cash flows from derivative instruments in cash flows from operating activities. The Company uses quoted prices to value its derivative instruments.

The notional amounts of outstanding forward contracts were as follows (in thousands):


	Buy Contracts
	October 27, 2012		January 28, 2012
Israeli shekel	$	26,349	$	42,637

Cash Flow Hedges. The Company designates and documents its foreign currency forward exchange contracts as cash flow hedges for certain operating expenses denominated in Israeli shekels. The Company evaluates and calculates the effectiveness of each hedge at least quarterly. The effective change is recorded in accumulated other comprehensive income and is subsequently reclassified to operating expense when the hedged expense is recognized. Ineffectiveness is recorded in interest and other income, net.

Other Foreign Currency Forward Contracts. The Company enters into foreign currency forward exchange contracts to hedge certain assets and liabilities denominated in various foreign currencies that it does not designate as hedges for accounting purposes. The maturities of these contracts are generally less than 12 months. Gains or losses arising from the remeasurement of these contracts to fair value each period are recorded in interest and other income, net.

The fair value of foreign currency exchange contracts was not significant as of any period presented.

- Definition

Fair Value Measurements

Fair Value Measurements

Note 6. 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—Include 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 its institutional money-market funds that are classified as cash equivalents and marketable investments in U.S. federal and state debt securities, which are valued primarily using quoted market prices. The Company’s Level 2 assets and liabilities include its marketable investments in corporate debt securities as the market inputs to value these instruments consist of market yields, reported trades and broker/dealer quotes, which are corroborated with observable market data. In addition, foreign currency exchange contracts are classified within Level 2 as the valuation inputs are based on quoted prices and market observable data of similar instruments. The Company’s Level 3 assets include its investments in auction rate securities, which are classified within Level 3 because there are currently no active markets for the auction rate securities and consequently the Company is unable to obtain independent valuations from market sources. Therefore, the auction rate securities are valued using a discounted cash flow model. Some of the inputs to the cash flow model are unobservable in the market. The total amount of assets measured using Level 3 valuation methodologies represented 0.3% of total assets as of October 27, 2012.

The tables below set forth, by level, the Company’s financial assets that were accounted for at fair value as of October 27, 2012 and January 28, 2012. The tables do not include assets and liabilities that are measured at historical cost or any basis other than fair value (in thousands):

Note 7. Goodwill and Acquired Intangible Assets, Net (in thousands)

Goodwill

The following table summarizes the activity related to the carrying value of goodwill:


Balance at January 28, 2012	$	2,031,991
Additions due to business combinations		147

Balance at October 27, 2012	$	2,032,138

Under U. S. GAAP, the Company is required to evaluate goodwill for impairment whenever events or changes in circumstances indicate that the carrying value of the goodwill may not be recoverable. This evaluation requires a comparison of the reporting unit’s fair value with its net book value, including goodwill. If this comparison indicates that the fair value is less than the net book value, then the implied fair value of the reporting unit’s goodwill is compared with its carrying value to determine whether an impairment loss is required to be recorded. The Company has only one reporting unit and the fair value of the reporting unit is determined by taking the market capitalization of the Company as determined through quoted market prices and adjusted for a control premium and other relevant factors. During the three months ended October 27, 2012, the Company experienced a continued decline in its stock price which caused a substantial reduction in the reporting unit’s excess fair value over its net book value. The Company determined its fair value was in excess of its carrying value and therefore no impairment of goodwill was recorded as of October 27, 2012. If the Company’s stock price continues to decline and further erode its total market capitalization, the Company may be required to record an impairment charge in the future that could be material to its operating results.

Income Tax

Note 8. Income Tax

The income tax provision for the three and nine months ended October 27, 2012 included the current income tax liability of $5.9 million and $14.5 million, respectively, which was primarily offset by net reductions in unrecognized tax benefits of $5.5 million in the three months ended October 27, 2012 and $11.5 million in the nine months ended October 27, 2012. These net reductions in unrecognized tax benefits primarily arose from the expiration of statute of limitations and from the settlement of audits in non-U.S. jurisdictions less increases in current unrecognized tax benefit estimates.

The income tax provision for the three and nine months ended October 29, 2011 included the current income tax liability of $5.9 million and $14.2 million, respectively, which was partially offset by a net reduction in unrecognized tax benefits of $2.8 million in the three months ended October 29, 2011 and $6.2 million in the nine months ended October 29, 2011 primarily due to the expiration of the statute of limitations in non-U.S. jurisdictions less increases in current unrecognized tax benefit estimates.

During the next 12 months, it is reasonably possible that the amount of unrecognized tax benefits could decrease due to a potential settlement with tax authorities and/or the expiration of applicable statutes of limitations. However, the amount cannot be reasonably estimated as the Company will have negotiations with various tax authorities throughout the year.

Commitments and Contingencies

Note 9. Commitments and Contingencies

Purchase Commitments

Under the Company’s manufacturing relationships with its foundry partners, cancellation of all outstanding purchase orders are allowed but require payment of all costs and expenses incurred through the date of cancellation. As of October 27, 2012, these foundries had incurred approximately $160.9 million of manufacturing costs and expenses related to the Company’s outstanding purchase orders.

Intellectual Property Indemnification

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 under an infringement claim as well as the customer’s attorneys’ fees and costs. The Company’s indemnification obligations generally do not expire after termination or expiration of the agreement containing the indemnification obligation. In certain cases, there are limits on and exceptions to the Company’s potential liability for indemnification. Although historically the Company has not made significant payments under these indemnification obligations, 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.

Contingencies

Carnegie Mellon Litigation. On March 6, 2009, Carnegie Mellon University (“CMU”) filed a complaint in the United States District Court for the Western District of Pennsylvania naming MSI and the Company as defendants and alleging patent infringement. CMU has asserted U.S. Patent Nos. 6,201,839 and 6,438,180 (collectively, the “CMU patents in suit”), which purportedly relate to read-channel integrated circuit devices and the HDD products incorporating such devices. The complaint seeks unspecified damages and an injunction. On June 1, 2009, MSI and the Company filed their answers and MSI filed counterclaims to the complaint seeking declaratory judgments of non-infringement and invalidity as to both of the asserted patents. The claim construction hearing was held on April 12 and 13, 2010. On April 29, 2010, MSI and the Company filed their amended answers and counterclaims. The Court issued a Markman ruling on October 1, 2010. MSI and the Company filed a motion for partial summary judgment of invalidity on December 22, 2010, which was denied on September 28, 2011. MSI and the Company filed a second motion for partial summary judgment of invalidity on November 2, 2011, which was denied on April 10, 2012. On April 20, 2012, MSI and the Company filed a motion for partial summary judgment of no infringement and no damages with respect to extraterritorial conduct, a summary judgment motion of no infringement and no damages with respect to licensed use and a summary judgment motion of non-infringement regarding certain claims. A hearing on summary judgment motions was held on July 10 and 11, 2012. On August 24, 2012, the Court granted in part and denied in part the motion of no infringement and no damages with respect to extraterritorial conduct; granted in part and denied in part the motion of no infringement and no damages with respect to licensed use; and granted the motion of non-infringement regarding certain claims. A jury trial began on November 26, 2012. In pre-trial proceedings, CMU alleged past damages in the amount of approximately $1.2 billion through July 2012, and also seeks enhanced damages, ongoing royalties, pre-judgment interest and attorneys’ fees. MSI and the Company strongly dispute their liability and the damages claimed by CMU, and further believe that they do not infringe any valid and enforceable claims of the asserted CMU patents in suit and intend to litigate this action vigorously (including any potential appeal, as necessary). Based on the nature of the litigation, the Company is currently unable to predict the final outcome of this lawsuit and therefore cannot determine the likelihood of loss nor estimate a range of possible loss.

Section 16(b) Litigation. On October 9, 2007, a purported shareholder of the Company filed a complaint for violation of Section 16(b) of the Exchange Act, which prohibits short swing trading, against the Company’s IPO underwriters. The complaint Vanessa Simmonds v. The Goldman Sachs Group, et al., Case No. C07-1632 filed in District Court for the Western District of Washington, seeks the recovery of short swing profits. The Company is named as a nominal defendant only, and no recovery is sought from the Company. In March 2009, the district court granted a motion to dismiss filed by the underwriter defendants, which caused the case against the Company to be dismissed. The plaintiff appealed to the U.S. Court of Appeals for the Ninth Circuit, and in December 2010, the Ninth Circuit reversed the dismissal and remanded to the district court. On January 25, 2011, the Ninth Circuit entered an order staying the mandate pending the filing of petitions for writ of certiorari in the United States Supreme Court by the underwriter defendants. Both sides have filed petitions for writ of certiorari to the United States Supreme Court. The Supreme Court denied plaintiff’s writ, but granted the underwriters’ writ, which argued that the case should have been dismissed on statute of limitations grounds. On March 26, 2012, the U.S. Supreme Court issued its opinion in the case. The Court vacated and remanded the Ninth Circuit’s decision and held that the two-year statute of limitations for actions under Section 16(b) is not automatically subject to equitable tolling pending the filing of the public disclosure statement required by Section 16(a) of the Act. On May 15, 2012, the Ninth Circuit entered an order remanding the cases of the non-moving issuer defendants (including the Company) to the District Court for proceedings consistent with the opinion of the U.S. Supreme Court and dismissing with prejudice the cases of the moving issuer defendants. On June 11, 2012, the plaintiff filed a Notice of Dismissal in the District Court, dismissing the action against the Company with prejudice as to the adequacy of the pre-suit demand letters in accordance with the Ninth Circuit’s opinion and without prejudice as to all other issues.

Jasmine Networks Litigation. On September 12, 2001, Jasmine Networks, Inc. (“Jasmine”) filed a lawsuit in the Santa Clara County Superior Court alleging claims against Marvell Semiconductor, Inc. (“MSI”) and three of its officers for allegedly improperly obtaining and using information and technologies during the course of the negotiations with its personnel regarding the potential acquisition of certain Jasmine assets by MSI.

The case proceeded to trial on September 20, 2010. On November 24, 2010, a Santa Clara County jury returned a verdict in favor of MSI on all claims. On January 7, 2011, the court entered judgment in MSI’s favor. Pursuant to California Civil Procedure provisions, Jasmine filed motions for a new trial and for a judgment notwithstanding the verdict. These motions were heard by the court on February 25, 2011 and denied in written orders. Jasmine has appealed and MSI is contesting the appeal vigorously. The Company is currently unable to predict the outcome of this lawsuit and therefore cannot determine the likelihood of loss nor estimate a range of possible loss.

Wage and Hour Class Action. On October 18, 2006, Dan Holton (“Holton”), a former employee of MSI, filed a civil complaint in Santa Clara County Superior Court. Holton alleges that MSI misclassified him as an exempt employee. Holton claims that due to its misclassification MSI owes him unpaid wages for overtime, penalties for missed meal periods, and various other penalties under the California Labor Code, as well as interest. Holton also pursues a cause of action for unfair business practices under the California Business & Profession Code. Holton brought his complaint as a class action. On July 8, 2009, the court granted certification of the following class: “All Individual Contributor Engineers who held the title of PCB Designer, Associate Engineer, Engineer, Staff Engineer and Senior Engineers, who at any time during the class period while holding these positions did not have a degree above a baccalaureate degree nor a degree above a baccalaureate degree in a field of science related to the work performed, and worked for MSI in California, at any time from October 19, 2002 through the present.” MSI disputed all of plaintiff’s class claims. On November 23, 2011, the parties executed a settlement agreement and plaintiffs filed their motion for preliminary approval of the settlement. The settlement was preliminarily approved by the Court on March 16, 2012. No class members objected to the settlement, and the Court approved the settlement at the final settlement approval hearing on July 6, 2012. The settlement amount, which was recorded in the Company’s financial statements in fiscal 2012, was not material to the Company’s results of operations.

USEI Litigation. On October 9, 2009, U.S. Ethernet Innovations, LLC (“USEI”) filed a complaint in the United States District Court for the Eastern District of Texas, in which USEI has accused a number of system manufacturers, including the Company’s customers, of patent infringement (the “USEI litigation”). Specifically, USEI has asserted that these customers infringe U.S. Patent Nos. 5,307,459, 5,434,872, 5,732,094 and 5,299,313 (collectively, the “USEI patents in suit”), which purportedly relate to Ethernet technologies. The complaint seeks unspecified damages and an injunction.

On May 4, 2010, MSI filed a motion to intervene in the USEI litigation, which was granted on May 19, 2010. On July 13, 2010, the court issued an order granting the Defendants’ motion to transfer the action to the Northern District of California; the case was formally transferred on August 23, 2010. On September 14, 2011, USEI withdrew its allegations against MSI for the ‘459 patent. On October 21, 2011, the court conducted a claim construction hearing, and a ruling was issued on January 31, 2012. A supplemental claim construction hearing was held on May 3, 2012, and a ruling was issued on August 29, 2012. MSI believes that it does not infringe any valid and enforceable claim of the USEI patents in suit, and intends to litigate this action vigorously. The Company is currently unable to predict the outcome of this lawsuit and therefore cannot determine the likelihood of loss nor estimate a range of possible loss.

Lake Cherokee Patent Litigation. On June 30, 2010, Lake Cherokee Hard Drive Technologies, L.L.C. filed a complaint in the United States District Court for the Eastern District of Texas. The complaint names MSI and seven other defendants, and alleges infringement of U.S. Patent Nos. 5,844,738 and 5,978,162 (collectively, the “Lake Cherokee patents in suit”). The Lake Cherokee patents in suit purportedly relate to read-channel integrated circuit devices, and allegedly, to certain unspecified HDD products incorporating such devices. The complaint seeks unspecified damages and a permanent injunction. MSI filed its answer and counterclaims to the complaint on September 13, 2010. Defendants filed a motion to transfer on April 1, 2011, which was denied on February 13, 2012. Lake Cherokee filed an amended complaint on April 21, 2011. MSI filed its answer and counterclaims to the amended complaint on May 9, 2011. A claim construction hearing was held on May 14, 2012, and a ruling was issued on August 6, 2012. Trial is set for August 5, 2013. MSI believes that it does not infringe any valid and enforceable claim of the Lake Cherokee patents in suit, and intends to litigate this action vigorously. The Company is currently unable to predict the outcome of this lawsuit and therefore cannot determine the likelihood of loss nor estimate a range of possible loss.

APT Patent Litigations. On January 18, 2011, Advanced Processor Technologies, LLC (“APT”), a subsidiary of Acacia Research Corp., filed a complaint in the United States District Court for the Eastern District of Texas. The complaint names MSI and eight other defendants and alleges infringement of U.S. Patent Nos. 6,047,354 (“’354 patent”) and 5,796,978 (“’978 patent”). The asserted patents purportedly relate to microprocessor technologies. The complaint seeks unspecified damages and a permanent injunction. A first amended complaint was filed on January 26, 2011. The first amended complaint continues to assert the ‘354 patent against MSI, but appears to no longer assert the ‘978 patent against MSI. MSI filed its answer and counterclaims on April 15, 2011. A claim construction hearing is scheduled for January 29, 2013, and jury selection is set for July 1, 2013. On March 23, 2012, APT filed a separate complaint in the United States District Court for the Eastern District of Texas. The complaint alleges that MSI infringes U.S. Patent Nos. 6,092,172 and 6,629,207. The asserted patents purportedly relate to microprocessor technologies. The complaint seeks unspecified damages and a permanent injunction. MSI filed its answer and counterclaims on May 25, 2012. A claim construction hearing is scheduled for May 14, 2013 and jury selection is set for January 6, 2014. A motion to consolidate the pre-trial schedule of the first case with the second case was filed on November 7, 2012. In both cases, ARM filed a motion to intervene on July 23, 2012 and a motion to transfer on July 27, 2012. MSI believes that it does not infringe any valid and enforceable claim of the APT patents in suit, and intends to litigate these actions vigorously. The Company is currently unable to predict the outcome of these lawsuits and therefore cannot determine the likelihood of loss nor estimate a range of possible loss.

MOSAID Litigation. On March 16, 2011, MOSAID Technologies Inc. filed suit in the United States District for the Eastern District of Texas against MSI and 16 other companies. The complaint alleges that defendants’ products, which operate in compliance with the IEEE 802.11a, 802.11b, 802.11g, and 802.11n standards, infringe the six asserted patents (U.S. Patent Nos. 5,131,006; 5,151,920; 5,422,887; 5,706,428; 6,563,768; 6,992,972). MSI filed its answer and counterclaims on June 9, 2011. On March 28, 2012, MSI and other defendants filed a motion to transfer. A claim construction hearing is scheduled for April 16, 2013 and jury selection is set for January 8, 2014. MSI believes that it does not infringe any valid and enforceable claim of the MOSAID patents in suit, and intends to litigate this action vigorously. The Company is currently unable to predict the outcome of this lawsuit and therefore cannot determine the likelihood of loss nor estimate a range of possible loss.

Azure Networks Litigation. On March 22, 2011, Azure Networks, LLC and Tri-County Excelsior Foundation filed suit in the Eastern District of Texas against MSI and eight other companies. The Complaint asserts U.S. Patent No. 7,756,129 against MSI’s Bluetooth products. MSI filed its answer and counterclaims on July 20, 2011. On December 9, 2011, defendants filed a motion to dismiss or transfer venue to S.D.N.Y. or, alternatively, to N.D. Cal., which was denied on June 25, 2012. On November 2, 2012, defendants filed a motion for summary judgment of invalidity. A claim construction hearing and hearing on defendants’ motion for summary judgment is scheduled for November 29, 2012 and trial is set for November 12, 2013. MSI believes that it does not infringe any valid and enforceable claim of the Azure Networks patents in suit, and intends to litigate this action vigorously. The Company is currently unable to predict the outcome of this lawsuit and therefore cannot determine the likelihood of loss nor estimate a range of possible loss.

Power Management Systems Litigation. On August 22, 2011, Power Management Systems LLC (“PMS”), a subsidiary of Acacia Research Corp., filed a complaint against the Company’s subsidiary Marvell Semiconductor, Ltd. (“MSL”) and other defendants, in the United States District Court for the District of Delaware. The complaint asserts U.S. Patent No. 5,504,909, which purportedly relates to a power management apparatus, against various products. The complaint seeks unspecified damages. On October 17, 2011, PMS amended its complaint by substituting MSL with MSI. MSI filed its answer and counterclaims on November 4, 2011. A claim construction hearing is scheduled for January 18, 2013 and trial is set for March 3, 2014. MSI believes that it does not infringe any valid and enforceable claim of the PMS’ patent in suit, and intends to litigate this action vigorously. The Company is currently unable to predict the outcome of this lawsuit and therefore cannot determine the likelihood of loss nor estimate a range of possible loss.

HSM/TPL Litigation. On September 1, 2011, HSM Portfolio, LLC and Technology Properties Limited, LLC filed a complaint against the Company and MSL in the United States District Court for the District of Delaware. The complaint also named numerous other defendants. The complaint asserts U.S. Patent No. 5,030,853, purportedly relating to high speed logic and memory circuitry, against various products. The complaint seeks unspecified damages. On January 9, 2012, HSM/TPL filed an amended complaint adding MSI to the case. On February 15, 2012, the Company and MSL were dismissed from the case. On July 18, 2012, HSM filed a second amended complaint against MSI, and MSI filed its answer and counterclaims on August 13, 2012. MSI believes that it does not infringe any valid and enforceable claim of the HSM/TPL patents in suit, and intends to litigate this action vigorously. The Company is currently unable to predict the outcome of this lawsuit and therefore cannot determine the likelihood of loss nor estimate a range of possible loss.

France Telecom Litigation. On June 26, 2012, France Telecom S.A. (“France Telecom”) filed a complaint against MSI in the United States District Court for the Southern District of New York. The complaint asserts U.S. Patent No 5,446,747 (the “’747 patent”) against MSI’s communications processors and thin modems. The complaint seeks unspecified damages as well as injunctive relief. MSI answered the complaint on July 18, 2012 and August 1, 2012. On July 30, 2012, MSI filed a motion to transfer the lawsuit to the United States District Court for the Northern District of California. On September 17, 2012, the Court granted MSI’s motion and transferred the case to the Northern District of California. A case management conference has been set in the Northern District of California for January 24, 2013. No new trial date has been set. MSI believes that it does not infringe any valid and enforceable claim of the ‘747 patent, and intends to litigate this action vigorously. The Company is currently unable to predict the outcome of this lawsuit and therefore cannot determine the likelihood of loss nor estimate a range of possible loss.

Freescale Litigation. On July 6, 2012, Freescale Semiconductor, Inc. (“Freescale”) filed a complaint against MSI in the United States District Court for the Western District of Texas. The complaint asserts U.S. Patent Nos. 6,920,316, 5,825,640, 5,943,274, 5,467,455 and 7,927,927 (collectively, the “Freescale patents in suit”) against certain of the Company’s integrated circuits and/or chipsets. The complaint seeks unspecified damages and a permanent injunction. On September 17, 2012, MSI filed a motion to dismiss the complaint for failure to state a claim pursuant to FRCP 12(b)(6) as to direct infringement of U.S. Patent No. 7,927,927, indirect infringement of the Freescale patents in suit, and willful infringement of the Freescale patents in suit. MSI believes that it does not infringe any valid and enforceable claim of the Freescale patents in suit, and intends to litigate this action vigorously. The Company is currently unable to predict the outcome of this lawsuit and therefore cannot determine the likelihood of loss nor estimate a range of possible loss.

General. The Company is also party to various other legal proceedings and claims arising in the normal course of business. The legal proceedings and claims described above could result in substantial costs and could divert the attention and resources of the Company’s management. Although the legal responsibility and financial impact with respect to each of these proceedings and claims cannot currently be ascertained, an unfavorable outcome in any of such actions could have a material adverse effect on the Company’s cash flows. As to each of the ongoing legal matters mentioned above, the Company is unable to predict its outcome and therefore cannot determine the likelihood of loss nor estimate a range of possible loss. Litigation is subject to inherent uncertainties and unfavorable rulings could occur. An unfavorable ruling in litigation could require the Company to pay damages or one-time license fees or royalty payments and could prevent the Company from manufacturing or selling some of its products or limit or restrict the type of work that employees involved in such litigation may perform for the Company, any of which could adversely affect financial results in future periods. The Company believes that it competes lawfully and that its marketing, business and intellectual property benefit its customers and shareholders, and it will continue to conduct a vigorous defense in these proceedings. There can be no assurance that these matters will be resolved in a manner that is not adverse to the Company’s business, financial condition, results of operations or cash flows.

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 include intellectual property indemnities to the Company’s customers in connection with the sales of its products, indemnities for liabilities associated with the infringement of other parties’ technology based upon the Company’s products, 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 unaudited condensed consolidated balance sheets as the amounts, if any, cannot be reasonably estimated. 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.

Stock Plans

Activity under the Company’s stock option plans for the nine months ended October 27, 2012 is summarized below (in thousands, except per share amounts):


	Time-Based Options					Market-Based Options					Total
	Number of Shares			Weighted Average Exercise Price		Number of Shares			Weighted Average Exercise Price		Number of Shares			Weighted Average Exercise Price
Balance at January 28, 2012		52,467		$	12.53		3,124		$	15.43		55,591		$	12.70
Granted		6,935		$	14.69		—		$	—		6,935		$	14.69
Exercised		(4,714	)	$	6.67		—		$	—		(4,714	)	$	6.67
Canceled/Forfeited		(2,814	)	$	16.04		(361	)	$	15.43		(3,175	)	$	15.97

Balance at October 27, 2012		51,874		$	13.16		2,763		$	15.43		54,637		$	13.28

Vested or expected to vest at October 27, 2012		50,620		$	13.13

Exercisable at October 27, 2012		39,582		$	13.10

For time-based stock options vested and expected to vest at October 27, 2012, the aggregate intrinsic value was $14.1 million and the weighted average remaining contractual term was 4.5 years. For time-based stock options exercisable at October 27, 2012, the aggregate intrinsic value was $11.6 million and the weighted average remaining contractual term was 3.5 years. There was no aggregate intrinsic value for market-based stock options at October 27, 2012 and the weighted average remaining contractual term of market-based stock options vested and expected to reach the end of the vesting period at October 27, 2012 was 8.5 years. The Company’s closing stock price as reported on the NASDAQ Global Select Market for all in-the-money options as of October 26, 2012 is used to calculate the aggregate intrinsic value.

As of October 27, 2012, the unamortized compensation expense for time-based stock options was $47.6 million and market-based stock options was $6.0 million. The unamortized compensation expense for time-based and market-based stock options will be amortized on a straight-line basis and is expected to be recognized over a weighted-average period of 2.5 years and 1.2 years, respectively.

Included in the following table is activity related to the non-vested portion of the restricted stock units for the nine months ended October 27, 2012 (in thousands, except for prices):


	Restricted Stock Units Outstanding			Weighted Average Grant Date Fair Value
Balance at January 28, 2012		9,646		$	17.38
Granted		7,113		$	14.90
Vested		(2,585	)	$	17.69
Canceled/Forfeited		(1,266	)	$	17.36

Balance at October 27, 2012		12,908		$	15.96

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. As of October 27, 2012, compensation costs related to restricted stock units not yet recognized amounted to $148.7 million. The unamortized compensation expense for restricted stock units will be amortized on a straight-line basis and is expected to be recognized over a weighted-average period of 1.6 years.

Employee Stock Purchase Plan

During the three months ended October 27, 2012 and October 29, 2011, the Company issued no shares under the 2000 Employee Stock Purchase Plan, as amended and restated (the “ESPP”). A total of 3.3 million shares were issued at a weighted-average price of $10.40 per share in the nine months ended October 27, 2012 and a total of 2.4 million shares were issued at a weighted-average price of $12.57 in the nine months ended October 29, 2011 under the ESPP. As of October 27, 2012, there was $46.5 million of unrecognized compensation cost related to the ESPP.

Share Repurchase Program

The Company repurchased 22.9 million of its common shares for $203.0 million in cash during the three months ended October 27, 2012 and 15.0 million of its common shares for $215.2 million in cash during the three months ended October 29, 2011. The Company repurchased 57.3 million of its common shares for $676.5 million in cash during the nine months ended October 27, 2012 and 74.3 million of its common shares for $1.2 billion in cash during the nine months ended October 29, 2011. The repurchased shares were retired immediately after the repurchases were completed. As of October 27, 2012, a total of 150.0 million cumulative shares have been repurchased under the Company’s share repurchase program for a total $2.1 billion in cash and there was $395.2 million remaining available for future share repurchases.

Subsequent to the end of the quarter through November 21, 2012, the Company repurchased an additional 1.5 million of its common shares for $11.5 million at an average price per share of $7.68.

Dividend Program

In May 2012, the Company announced the initiation of paying its first quarterly dividend of $0.06 per share. The Company intends to pay a regular quarterly cash dividend on its common shares subject to, among other things, the best interests of its shareholders, the Company’s results of operations, cash balances and future cash requirements, financial condition, statutory requirements of Bermuda law and other factors that the Company’s board of directors may deem relevant. As a result, cash dividends of $0.06 per share were paid for a total of $33.5 million in the three months ended October 27, 2012 and a total of $67.0 million in the nine months ended October 27, 2012.

Share-Based Compensation

Note 11. Share-Based Compensation

The following table presents details of share-based compensation expenses by functional line item (in thousands):


	Three Months Ended				Nine Months Ended
	October 27,		October 29,		October 27,		October 29,
	2012		2011		2012		2011
Cost of goods sold	$	1,944	$	1,940	$	5,842	$	5,551
Research and development		22,565		21,905		62,152		63,626
Selling and marketing		3,101		3,402		9,595		9,263

	$	30,374	$	30,611	$	90,794	$	88,446

Share-based compensation capitalized in inventory was $1.6 million at October 27, 2012 and $2.1 million at January 28, 2012.

Valuation Assumptions

The following weighted average assumptions were used for each respective period to calculate the fair value of each time-based stock option award on the date of grant using the Black-Scholes valuation model and of each market-based equity award using a Monte Carlo simulation model:


	Three Months Ended						Nine Months Ended
	October 27,			October 29,			October 27,			October 29,
	2012			2011			2012			2011
Time-based Stock Options:
Weighted average fair value	$	3.27		$	5.97		$	5.57		$	6.08
Expected volatility		46	%		49	%		44	%		43	%
Expected term (in years)		4.8			4.8			4.8			4.8
Risk-free interest rate		0.7	%		1.0	%		0.9	%		2.0	%
Expected dividend yield		2.3	%		—			0 - 2.3	%		—


	Nine Months Ended
	October 27,			October 29,
	2012			2011
Market-based Stock Options:
Weighted average fair value	$	—		$	5.08
Expected volatility		—	%		42	%
Risk-free interest rate		—	%		0.9 - 3.6	%

There were no market-based stock options granted during the three and nine months ended October 27, 2012 or during the three months ended October 29, 2011. The above table includes market-based stock options granted during the three months ended April 30, 2011. The fair value of each market-based stock option award is estimated on the date of grant using a Monte Carlo simulation model that uses the assumptions noted in the above table, including the same volatility applied to the Company’s time-based options. Because a Monte Carlo simulation model incorporates ranges of assumptions for inputs, those ranges are disclosed where applicable. The Company uses historical data to estimate employee termination within the valuation model. The expected term of 2.66 years for market-based stock options granted during the three months ended April 30, 2011 was derived from the output of the valuation model and represents the period of time that options granted are expected to be outstanding.


	Nine Months Ended
	October 27,			October 29,
	2012			2011
Employee Stock Purchase Plan:
Estimated fair value	$	3.77		$	4.09
Volatility		39	%		46	%
Expected term (in years)		1.3			0.5
Risk-free interest rate		0.2	%		0.2	%
Dividend yield		2.0	%		—

Under the ESPP, there were no stock purchase rights granted in the three months ended October 27, 2012 and October 29, 2011. The expected volatility for awards granted during the nine months ended October 27, 2012 and October 29, 2011 is based on an equally weighted combination of historical stock price volatility and implied volatility derived from traded options on the Company’s stock in the marketplace.

The Company and Basis of Presentation (Policies)	9 Months Ended
The Company and Basis of Presentation (Policies)	Oct. 27, 2012
The Company	*The Company* Marvell Technology Group Ltd., a Bermuda company (the “Company”), is a leading global semiconductor provider of high performance application specific standard products. The Company’s core strength of expertise 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 ARM-based microprocessor integrated circuits. The Company also develops platforms that it defines as integrated hardware and software that incorporate digital computing technologies designed and configured to provide an optimal computing solution compared to individual components. The Company’s broad product portfolio includes devices for data storage, enterprise-class Ethernet data switching, Ethernet physical-layer transceivers, handheld cellular, Ethernet-based wireless networking, personal area networking, Ethernet-based PC connectivity, control plane communications controllers, video-image processing and power management solutions.
Reclassification	*Reclassification* Certain amounts in the unaudited condensed consolidated financial statements and notes to the unaudited condensed consolidated financial statements for prior years have been reclassified to conform to the fiscal 2013 presentation. Net operating results have not been affected by these reclassifications.
Basis of Presentation	*Basis of Presentation* The Company’s fiscal year is the 52- or 53-week period ending on the Saturday closest to January 31. In a 52-week year, each fiscal quarter consists of 13 weeks. The additional week in a 53-week year is added to the fourth quarter, making such quarter consist of 14 weeks. Fiscal 2013 has a 53-week period and therefore, the fourth quarter which ends on February 2, 2013 includes 14 weeks. Fiscal 2012 had a 52-week period. The unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by GAAP for annual financial statements. In the opinion of management, all adjustments consisting of normal and recurring entries considered necessary for a fair statement of the results for the interim periods have been included in the Company’s balance sheet as of October 27, 2012, the results of its operations for the three and nine months ended October 27, 2012 and October 29, 2011, and its cash flows for the nine months ended October 27, 2012 and October 29, 2011. The January 28, 2012 condensed consolidated balance sheet data was derived from the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended January 28, 2012 but does not include all disclosures required for annual periods. These condensed consolidated financial statements and related notes are unaudited and should be read in conjunction with the Company’s audited financial statements and related notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended January 28, 2012 as filed on March 27, 2012 with the Securities and Exchange Commission. The results of operations for the three and nine months ended October 27, 2012 are not necessarily indicative of the results that may be expected for any other interim period or for the full fiscal year.
Use of Estimates	*Use of Estimates* The preparation of consolidated financial statements in conformity with 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 assets and liabilities. On an on-going 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, income taxes, litigation and other contingencies. In addition, the Company uses assumptions when employing the Monte Carlo simulation and Black-Scholes valuation models to calculate the fair value of share-based awards that are granted. When carrying values of certain assets and liabilities are not readily available from other sources, their carrying values are estimated based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from these estimates, and such differences could affect the results of operations reported in future periods.
Principles of Consolidation	*Principles of Consolidation* The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated. The functional currency of the Company and its subsidiaries is the United States dollar.
Accounting Pronouncements Recently Adopted	*Accounting Pronouncements Recently Adopted* The Company adopted the new accounting standard that provides additional guidance on fair value measurements and related disclosures at the beginning of fiscal 2013. This guidance clarifies the application of existing guidance on fair value measurement for non-financial assets and requires the disclosure of quantitative information about the unobservable inputs used in a fair value measurement. The adoption of this guidance had no impact on the Company’s financial statements. The Company also adopted the new accounting standard that permits an entity the option to present the total of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements at the beginning of fiscal 2013. This amended guidance eliminates the option to present the components of other comprehensive income as part of the statement of changes in shareholders’ equity. As a result, the Company has separately presented the Statements of Comprehensive Income as part of its unaudited condensed consolidated financial statements. The Company also adopted the new accounting standard that amends the previous guidance regarding the testing of goodwill for impairment at the beginning of fiscal 2013. This amended guidance allows an entity to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. An entity no longer is required to calculate the fair value of a reporting unit unless the entity determines, based on a qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. The adoption of this guidance had no impact on the Company’s financial statements.
Accounting Pronouncements Not Yet Effective	*Accounting Pronouncements Not Yet Effective* In July 2012, the Financial Accounting Standards Board issued an amendment to its guidance regarding the testing of indefinite-lived intangible assets for impairment. This amended guidance allows an entity first to assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test in accordance with the guidance on the impairment of intangible assets other than goodwill. This amended guidance is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. The adoption of this guidance is not expected to have an impact on the Company’s financial statements.

- Definition

Cash includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the customer may deposit additional funds at any time and effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid Investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Short-term investments, exclusive of cash equivalents, generally consist of marketable securities intended to be sold within one year (or the normal operating cycle if longer) and may include trading securities, available-for-sale securities, or held-to-maturity securities (if maturing within one year), as applicable.

- Definition

This item represents the aggregate carrying amount of all cost-method investments as reported on or included in the balance sheet. The original cost of the investments may differ from the aggregate carrying amount disclosed due to various adjustments such as: (i) dividends received in excess of earnings after the date of investment that are considered a return of investment and therefore recorded as reductions to cost of the investment, or (ii) a series of operating losses of an investee or other factors which may indicate that a decrease in value of the investment has occurred which is other than temporary and accordingly such decrease in value has been recognized.
