The Company and Its Significant Accounting Policies	Mar. 28, 2015
Organization, Consolidation and Presentation of Financial Statements [Abstract]
THE COMPANY AND ITS SIGNIFICANT ACCOUNTING POLICIES	THE COMPANY AND ITS SIGNIFICANT ACCOUNTING POLICIES On February 22, 2014, RF Micro Devices, Inc. ("RFMD" and referred to herein as the "Company" prior to January 1, 2015) and TriQuint Semiconductor, Inc. ("TriQuint") entered into an Agreement and Plan of Merger and Reorganization (as subsequently amended on July 15, 2014, the "Merger Agreement") providing for the business combination of RFMD and TriQuint ("Business Combination") under a new holding company named Qorvo, Inc. (formerly named Rocky Holding, Inc.) ("Qorvo" and referred to herein as the "Company" as of and following January 1, 2015). The stockholders of both RFMD and TriQuint approved the Merger Agreement at each company's special meeting of stockholders on September 5, 2014. During the third quarter of fiscal 2015, all necessary regulatory approvals were received to complete the Business Combination. The Business Combination closed on January 1, 2015 (fourth quarter of fiscal 2015). For financial reporting and accounting purposes, RFMD was the acquirer of TriQuint. The results presented in the Consolidated Financial Statements and Notes to the Consolidated Financial Statements reflect those of RFMD prior to the completion of the Business Combination on January 1, 2015 and those of Qorvo subsequent to the completion of the Business Combination. The Company is a leading provider of core technologies and radio frequency (“RF”) solutions for mobile, infrastructure and defense and aerospace applications. The Company is a preferred supplier to the world’s leading companies that serve the mobile device, networks infrastructure and defense and aerospace markets. The Company’s design and manufacturing expertise encompasses many semiconductor process technologies, which it sources both internally and through external suppliers. The Company operates worldwide with its design, sales and manufacturing facilities located throughout Asia, Europe and North America. The Company’s primary design and manufacturing facilities are located in North Carolina, Oregon, Texas and Florida and its primary assembly and test facilities are located in China, Costa Rica and Texas. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The results of operations, assets and liabilities associated with the business combination with TriQuint have been included in the Company's financial statements from the acquisition date of January 1, 2015 (see Note 5). The results of operations, assets and liabilities associated with the acquisition of Amalfi Semiconductor, Inc. (“Amalfi”) have been included in the Company's financial statements from the acquisition date of November 9, 2012 (see Note 5). Accounting Periods The Company uses a 52- or 53-week fiscal year ending on the Saturday closest to March 31 of each year. The most recent three fiscal years ended on March 28, 2015, March 29, 2014, and March 30, 2013. Fiscal years 2015, 2014 and 2013 were 52-week years. Use of Estimates The preparation of the Consolidated Financial Statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The actual results that the Company experiences may differ materially from its estimates. The Company makes estimates for the returns reserve, rebates, allowance for doubtful accounts, inventory valuation including reserves, warranty reserves, income tax valuation, current and deferred income taxes, uncertain tax positions, non-marketable equity investments, other-than-temporary impairments of investments, goodwill, long-lived assets and other financial statement amounts on a regular basis and makes adjustments based on historical experiences and expected future conditions. Accounting estimates require difficult and subjective judgments and actual results may differ from the Company’s estimates. Cash and Cash Equivalents Cash and cash equivalents consist of demand deposit accounts, money market funds, and other temporary, highly-liquid investments with original maturities of three months or less when purchased. Investments Investments available-for-sale at March 28, 2015 consisted of U.S. government/agency securities, corporate debt, marketable equity securities, auction rate securities (ARS), and money market funds. Investments available-for-sale at March 29, 2014 consisted of U.S. government/agency securities, ARS, and money market funds. Available-for-sale investments with an original maturity date greater than approximately three months and less than one year are classified as current investments. Available-for-sale investments with an original maturity date exceeding one year are classified as long-term. Available-for-sale securities are carried at fair value with the unrealized gains and losses, net of tax, reported in "Other comprehensive income (loss)." The cost of securities sold is based on the specific identification method and any realized gain or loss is included in “Other (expense) income.” The amortized cost of available-for-sale securities is adjusted for amortization of premium and accretion of discounts, which are included as a portion of interest. The Company assesses individual investments for impairment quarterly. Investments are impaired when the fair value is less than the amortized cost. If an investment is impaired, the Company evaluates whether the impairment is other-than-temporary. A debt investment impairment is considered other-than-temporary if (i) the Company intends to sell the security, (ii) it is more likely than not that the Company will be required to sell the security before recovery of the entire amortized cost basis, or (iii) the Company does not expect to recover the entire amortized cost basis of the security (a credit loss). Other-than-temporary declines in the Company's debt securities are recognized as a loss in the statement of operations if due to credit loss; all other losses on debt securities are recorded in "Other comprehensive income (loss)." The previous amortized cost basis less the other-than-temporary impairment becomes the new cost basis and is not adjusted for subsequent recoveries in fair value. Inventories Inventories are stated at the lower of cost or market determined using the average cost method. The Company’s business is subject to the risk of technological and design changes. The Company evaluates inventory levels quarterly against sales forecasts on a product family basis to evaluate its overall inventory risk. Reserves are adjusted to reflect inventory values in excess of forecasted sales which include management's analysis and assessment of overall inventory risk. In the event the Company sells inventory that had been covered by a specific inventory reserve, the sale is recorded at the actual selling price and the related cost of goods sold is recorded at the full inventory cost, net of the reserve. Abnormal production levels are charged to the income statement in the period incurred rather than as a portion of inventory cost. Product Warranty The Company generally sells products with a limited warranty on product quality. The Company accrues for known warranty issues if a loss is probable and can be reasonably estimated, and accrues for estimated incurred but unidentified issues based on historical activity. The accrual and the related expense for known product warranty issues were not significant during the periods presented. Due to product testing and the short time typically between product shipment and the detection and correction of product failures and the historical rate of losses, the accrual and related expense for estimated incurred but unidentified issues were not significant during the periods presented. Property and Equipment Property and equipment are stated at cost, less accumulated depreciation. Depreciation of property and equipment is computed using the straight-line method over the estimated useful lives of the assets, ranging from one year to 39 years. The Company’s assets acquired under capital leases and leasehold improvements are amortized over the lesser of the asset life or lease term (which is reasonably assured) and included in depreciation. The Company performs a review if facts and circumstances indicate that the carrying amount of assets may not be recoverable or that the useful life is shorter than had originally been estimated. The Company assesses the recoverability of the assets held for use by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining estimated useful lives against their respective carrying amounts. Impairment, if any, is based on the excess of the carrying amount over the fair value of those assets. If the Company determines that the useful lives are shorter than the Company had originally estimated, the net book value of the assets is depreciated over the newly determined remaining useful lives. The Company identifies property and equipment as “held for sale” based on the current expectation that, more likely than not, an asset or asset group will be sold or otherwise disposed. The held for sale assets cease depreciation once the assets are classified to the held for sale category at the lesser of their carrying value or their fair market value less costs to sell. The Company capitalizes the portion of the interest expense related to certain assets that are not ready for their intended use and this amount is depreciated over the estimated useful lives of the qualified assets. The Company additionally records capital-related government grants earned as a reduction to property and equipment and depreciates such grants over the estimated useful lives of the associated assets. Other Receivables The Company records miscellaneous non-product receivables that are collectible within 12 months in “Other receivables,” such as value-added tax receivables ($15.2 million as of March 28, 2015 and $10.1 million as of March 29, 2014, which are reported on a net basis), precious metal reclaims submitted for payment, interest receivables and other miscellaneous items. Goodwill and Intangible Assets Goodwill is recorded when the purchase price paid for a business exceeds the estimated fair value of the net identified tangible and intangible assets acquired. Intangibles are recorded when such assets are acquired by purchase or license. The value of the Company's intangibles, including goodwill, could be impacted by future adverse changes such as: (i) any future declines in the Company's operating results; (ii) a decline in the value of technology company stocks, including the value of the Company's common stock; (iii) a prolonged or more significant slowdown in the worldwide economy or the semiconductor industry; or (iv) failure to meet the performance projections included in the Company's forecasts of future operating results. Goodwill and Other Intangible Assets with Indefinite Lives The Company has determined that its reporting units as of fiscal 2015 are MP and IDP for purposes of allocating and testing goodwill. In evaluating its reporting units, the Company first considers its operating segments and related components in accordance with FASB guidance. Goodwill is allocated to the reporting units that are expected to benefit from the synergies of the business combinations generating the underlying goodwill. As of March 28, 2015, the Company's goodwill balance of $2,140.6 million is allocated between its MP and IDP reporting units. The Company accounts for goodwill and indefinite-lived intangible assets in accordance with the FASB's authoritative guidance, which requires that they be tested annually for impairment or earlier if facts and circumstances indicate that they may be impaired. The Company performs its annual impairment test for goodwill and indefinite-lived intangible assets on the first day of the fourth quarter in each fiscal year. Indefinite-lived intangible assets consists of in-process research and development ("IPRD"). The Company has the option to perform a qualitative assessment (commonly referred to as "step zero") to determine whether further quantitative analysis for impairment of goodwill or indefinite-lived intangible assets is necessary. In performing step zero for the impairment test, the Company is required to make assumptions and judgments including but not limited to the following: the evaluation of macroeconomic conditions as related to the Company's business, industry and market trends, and the overall future financial performance of the Company's reporting units and future opportunities in the markets in which they operate. The Company also considers recent fair value calculations of its indefinite-lived intangible assets and reporting units as well as cost factors such as changes in raw materials, labor or other costs. If the step zero analysis indicates that it is more likely than not that the fair value of a reporting unit or indefinite-lived asset is less than its respective carrying value including goodwill, then the Company would perform an additional quantitative analysis. For goodwill, this involves a two-step process. The first step compares the fair value of the reporting unit, including its goodwill, to its carrying value. If the carrying value of the reporting unit exceeds its fair value, then the second step of the process is performed to determine the amount of impairment. The second step compares the implied fair value of the reporting unit's goodwill to the carrying value of the goodwill. An impairment charge is recognized for the amount the carrying value of the reporting unit's goodwill exceeds its implied fair value. For indefinite-lived intangible assets, the quantitative analysis compares the carrying value of the asset to its fair value and an impairment charge is recognized for the amount its carrying value exceeds its fair value. Determining the fair value of reporting units, indefinite-lived intangible assets and implied fair value of a reporting unit's goodwill is reliant upon estimated future revenues, profitability and cash flows and consideration of market factors. Assumptions, judgments and estimates are complex, subjective and can be affected by a variety of factors, including external factors such as industry and economic trends, and internal factors such as changes in the Company's business strategy or its internal forecasts. Although the Company believes the assumptions, judgments and estimates it has made have been reasonable and appropriate, different assumptions, judgments and estimates could materially affect the Company's results of operations. The Company performed a step zero analysis for its goodwill impairment test in the fourth quarter of fiscal 2015. As a result of this analysis, no further quantitative impairment test was deemed necessary for fiscal 2015. There was no impairment of goodwill as a result of the Company's annual impairment tests completed during the fourth quarters of fiscal years, 2015, 2014 and 2013. In fiscal 2015, as a result of the Business Combination, the Company recorded IPRD of $470.0 million. IPRD was recorded at fair value as of the date of acquisition as an indefinite-lived intangible asset until the completion or abandonment of the associated research and development efforts or impairment. The fair value of the acquired IPRD was determined based on an income approach using the "excess earnings method," which estimated the value of the intangible assets by discounting the future projected earnings of the asset to present value as of the valuation date. Upon completion of development, acquired IPRD assets are transferred to finite-lived intangible assets and amortized over their useful lives. See Note 7 for additional information regarding an impairment of assets recorded in the fourth quarter of fiscal 2014. Intangible Assets with Definite Lives Intangible assets are recorded when such assets are acquired by purchase or license. Finite-lived intangible assets consist primarily of technology licenses, customer relationships, developed technology, a wafer supply agreement, trade names and backlog resulting from business combinations and are subject to amortization. Technology licenses are recorded at cost and are amortized on a straight-line basis over the lesser of the estimated useful life of the technology or the term of the license agreement, ranging from approximately five to eight years. The fair value of customer relationships acquired during fiscal years 2013 and 2015 was determined based on an income approach using the “with and without method," in which the value of the asset is determined by the difference in discounted cash flows of the profitability of the Company "with" the asset and the profitability of the Company "without" the asset. Customer relationships are amortized on a straight-line basis over the estimated useful life, ranging from three to ten years. The fair value of developed technology acquired during fiscal years 2013 and 2015 was determined based on an income approach using the "excess earnings method," which estimated the value of the intangible assets by discounting the future projected earnings of the asset to present value as of the valuation date. Developed technology is amortized on a straight-line basis over the estimated useful life, ranging from four to six years. The fair value of the wafer supply agreement was determined using the incremental income method, which is a discounted cash flow method within the income approach. Under this method, the fair value was estimated by discounting to present value the additional savings from expense reductions in operations at a discount rate to reflect the risk inherent in the wafer supply agreement as well as any tax benefits. The wafer supply agreement is amortized on a units of use activity method and has a useful life of approximately four years. The fair value of trade names acquired in fiscal 2015 was determined based on an income approach using the "relief from royalty method," in which the value of the asset is determined by discounting the future projected cash flows generated from the trade name's estimated royalties. Trade names are amortized on a straight-line basis over the estimated useful life of three years. The fair value of backlog acquired in fiscal 2015 was determined based on an income approach using the "excess earnings method" and is amortized on a straight-line basis over the estimated useful life of one year. The Company regularly reviews identified intangible assets to determine if facts and circumstances indicate that the useful life is shorter than it originally estimated or that the carrying amount of the assets may not be recoverable. If such facts and circumstances exist, the Company assesses the recoverability of identified intangible assets by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. Impairments, if any, are based on the excess of the carrying amount over the fair value of those assets and occur in the period in which the impairment determination was made. Revenue Recognition The Company's net revenue is generated principally from sales of semiconductor products. The Company recognizes revenue from product sales when the fundamental criteria are met, such as the time at which the title and risk and rewards of product ownership are transferred to the customer, price and terms are fixed or determinable, no significant vendor obligation exists and collection of the resulting receivable is reasonably assured. Sales of products are generally made through either the Company's sales force, manufacturers' representatives or through a distribution network. Revenue from the majority of the Company’s products is recognized upon shipment of the product to the customer from a Company-owned or third-party location. Some revenue is recognized upon receipt of the shipment by the customer. The Company has limited rebate programs offering price protection to certain distributors. These rebates represent less than 1% of net revenue and can be reasonably estimated based on specific criteria included in the rebate agreements and other known factors at the time. The Company reduces revenue and records reserves for product returns and allowances for price protection and stock rotation based on historical experience or specific identification depending on the contractual terms of the arrangement. The Company also recognizes a portion of its net revenue through other agreements such as non-recurring engineering fees, contracts for research and development work, royalty income, intellectual property (IP) revenue, and service revenue. These agreements are collectively less than 1% of consolidated revenue on an annual basis. Revenue from these agreements is recognized when the service is completed or upon certain milestones, as provided for in the agreements. Revenue from certain contracts is recognized on the percentage of completion method based on the costs incurred to date and the total contract amount, plus the contractual fee. If these contracts experience cost overruns, the percentage of completion method is used to determine revenue recognition. Revenue from fixed price contracts is recognized when the required deliverable is satisfied. Royalty income is recognized based on a percentage of sales of the relevant product reported by licensees during the period. The Company additionally licenses or sells its rights to use portions of its IP portfolio, which includes certain patent rights useful in the manufacture and sales of certain products. IP revenue recognition is dependent on the terms of each agreement. The Company will recognize IP revenue (i) upon delivery of the IP and (ii) if the Company has no substantive future obligation to perform under the arrangement. The Company will defer recognition of IP revenue where future performance obligations are required to earn the revenue or the revenue is not guaranteed. Revenue from services is recognized during the period that the service is performed. Accounts receivable are recorded for all revenue items listed above and do not bear interest. The Company evaluates the collectability of accounts receivable based on a combination of factors. In cases where the Company is aware of circumstances that may impair a specific customer’s ability to meet its financial obligations subsequent to the original sale, the Company will record an allowance against amounts due, and thereby reduce the receivable to the amount the Company reasonably believes will be collected. For all other customers, the Company recognizes allowances for doubtful accounts based on the length of time the receivables are past due, industry and geographic concentrations, the current business environment and the Company’s historical experience. The Company's terms and conditions do not give its customers a right of return associated with the original sale of its products. However, the Company will authorize sales returns under certain circumstances, which include perceived quality problems, courtesy returns and like-kind exchanges. The Company evaluates its estimate of returns by analyzing all types of returns and the timing of such returns in relation to the original sale. Reserves are adjusted to reflect changes in the estimated returns versus the original sale of product. Shipping and Handling Cost The Company recognizes amounts billed to a customer in a sale transaction related to shipping and handling as revenue. The costs incurred by the Company for shipping and handling are classified as cost of goods sold in the Consolidated Statements of Operations. Research and Development The Company charges all research and development costs to expense as incurred. Advertising Costs The Company expenses advertising costs as incurred. The Company recognized advertising expense of $0.5 million, $0.1 million, and $0.4 million for fiscal years 2015, 2014 and 2013, respectively. Precious Metals Reclaim The Company uses historical experience to estimate the amount of reclaim on precious metals used in manufacturing at the end of each period and state the reclaim value at the lower of average cost or market. The estimated value to be received from precious metal reclaim is included in "Other current assets" and reclaims submitted for payment are included are included in "Other receivables" on the Consolidated Balance Sheets. Income Taxes The Company accounts for income taxes under the liability method, which requires recognition of deferred tax assets and liabilities for the temporary differences between the financial reporting and tax basis of assets and liabilities and for tax carryforwards. Deferred tax assets and liabilities are measured using the enacted statutory tax rates in effect for the years in which the differences are expected to reverse. A valuation allowance is provided against deferred tax assets to the extent the Company determines it is more likely than not (a likelihood of more than 50 percent) that some portion or all of its deferred tax assets will not be realized. A minimum recognition threshold is required to be met before the Company recognizes the benefit of an income tax position in its financial statements. The Company’s policy is to recognize accrued interest and penalties, if incurred, on any unrecognized tax benefits as a component of income tax expense. It is the Company’s policy to invest the earnings of foreign subsidiaries indefinitely outside the U.S. Accordingly, the Company does not record a deferred tax liability for U.S. income taxes on unremitted foreign earnings. Stock-Based Compensation Under FASB ASC 718, “Compensation – Stock Compensation," stock-based compensation cost is measured at the grant date based on the estimated fair value of the award using an option pricing model for stock options (Black-Scholes) and market price for restricted stock units, and is recognized as expense over the employee's requisite service period. As of March 28, 2015, total remaining unearned compensation cost related to nonvested restricted stock units and options was $153.0 million, which will be amortized over the weighted-average remaining service period of approximately 1.3 years. Foreign Currency Translation The financial statements of foreign subsidiaries have been translated into U.S. dollars in accordance with FASB ASC 830, “Foreign Currency Matters.” The functional currency for most of the Company’s international operations is the U.S. dollar. The functional currency for the remainder of the Company’s foreign subsidiaries is the local currency. Assets and liabilities denominated in foreign currencies are translated using the exchange rates on the balance sheet dates. Revenues and expenses are translated using the average exchange rates throughout the year. Translation adjustments are shown separately as a component of “Accumulated other comprehensive loss” within “Stockholders’ equity” in the Consolidated Balance Sheets. Foreign currency transaction gains or losses (transactions denominated in a currency other than the functional currency) are reported in “Other (expense) income” in the Consolidated Statements of Operations. Recent Accounting Pronouncements Accounting Pronouncements Not Yet Effective In May 2014, the FASB issued Accounting Standards Update ("ASU") 2014-09, "Revenue from Contracts with Customers" that amends existing guidance on revenue recognition. The new guidance is based on principles that an entity will recognize revenue to depict the transfer of goods and services to customers at an amount the entity expects to be entitled to in exchange for those goods and services. The guidance requires additional disclosures regarding the nature, amount, timing, and uncertainty of cash flows and both qualitative and quantitative information about contracts with customers and applied significant judgments. The new authoritative guidance will become effective in the first quarter of fiscal 2018, using one of two retrospective methods of adoption. The Company has not determined which method it will adopt and is currently evaluating the effects the new guidance will have on its consolidated financial statements. Accounting Pronouncements Recently Adopted In July 2013, the FASB issued ASU 2013-11, “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” ASU 2013-11 requires an unrecognized tax benefit, or a portion of an unrecognized tax benefit, to be presented in the financial statements as a reduction of a deferred tax asset or a tax credit carryforward, excluding certain exceptions. This ASU was effective for the Company beginning in the first quarter of fiscal 2015 and the adoption did not have a material impact on the Company's consolidated financial statements.

Risks and Uncertainties [Abstract]

CONCENTRATIONS OF CREDIT RISK

The Company’s principal financial instrument subject to potential concentration of credit risk is accounts receivable, which is unsecured. The Company provides an allowance for doubtful accounts equal to estimated losses expected to be incurred in the collection of accounts receivable. The Company has adopted credit policies and standards intended to accommodate industry growth and inherent risk and it believes that credit risks are moderated by the financial stability of its major customers, conservative payment terms and the Company’s strict credit policies.

Revenue from significant customers, those representing 10% or more of total revenue for the respective periods, is summarized as follows:



	Fiscal Year
	2015	2014	2013
Samsung Electronics, Co., Ltd. (Samsung)	14%	25%	22%

In addition, the Company sold its products to another end customer through multiple contract manufacturers, which in the aggregate accounted for approximately 32%, 20% and 9% of total revenue in fiscal years 2015, 2014 and 2013, respectively. The majority of the revenue from these customers was from the sale of the Company’s mobile products.

Samsung accounted for approximately 7%, 25% and 29% of the Company's total accounts receivable balance as of March 28, 2015, March 29, 2014 and March 30, 2013, respectively.

Fair Value of Financial Instruments

The Company measures the fair value of its marketable securities, which are comprised of U.S. government/agency securities, corporate debt, marketable equity securities, auction rate securities (ARS), and money market funds. Marketable securities are reported in cash and cash equivalents, short-term investments and long-term investments on the Company’s Consolidated Balance Sheets and are recorded at fair value and the related unrealized gains and losses are included in "Accumulated other comprehensive loss," a component of stockholders’ equity, net of tax.

Recurring Fair Value Measurements

The fair value of the financial assets measured at fair value on a recurring basis was determined using the following levels of inputs as of March 28, 2015 and March 29, 2014 (in thousands):



					Total		Quoted Prices In Active Markets For Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)

(1) ARS are debt instruments with interest rates that reset through periodic short-term auctions. The Company's Level 2 ARS are valued based on quoted prices for identical or similar instruments in markets that are not active.

(2) Corporate debt includes corporate bonds and commercial paper which are valued using observable market prices for identical securities that are traded in less active markets.

(3) The non-qualified deferred compensation plan provides eligible employees and members of the Board of Directors with the opportunity to defer a specified percentage of their cash compensation. The Company includes the asset deferred by the participants in the “Other current assets” and “Other non-current assets” line items of its Consolidated Balance Sheets and the Company's obligation to deliver the deferred compensation in the "Other current liabilities" and “Other long-term liabilities” line items of its Consolidated Balance Sheets.

As of March 28, 2015 and March 29, 2014, the Company did not have any Level 3 assets or liabilities.

Nonrecurring Fair Value Measurements

The Company's non-financial assets, such as intangible assets and property and equipment, are measured at fair value when there is an indicator of impairment, and recorded at fair value only when an impairment charge is recognized (see Note 7 for an IPRD impairment recorded in the fourth quarter of fiscal 2014). During the first quarter of fiscal 2014, the Company recorded a $1.7 million impairment of certain property and equipment as a result of the phase out of manufacturing and the then-pending sale of its U.K. manufacturing facility. As of June 29, 2013, the fair value of these impaired assets was estimated to be $0.8 million using a significant Level 3 unobservable input (market valuation approach). The market valuation approach uses prices and other relevant information generated primarily by recent market transactions involving similar or comparable assets, as well as the Company's experience. During the second quarter of fiscal 2014, the Company sold its U.K. manufacturing facility, which resulted in a loss on these impaired assets of $0.6 million.

The Company's Consolidated Balance Sheet as of March 28, 2015, includes non-financial assets and liabilities measured at fair value as a result of the Business Combination (see Note 5).

Other Fair Value Disclosures

The carrying values of cash and cash equivalents, accounts receivable, accounts payable and other accrued liabilities approximate fair values because of the relatively short-term maturities of these instruments.

BUSINESS ACQUISITION DISCLOSURE [Abstract]

Business Acquisition

BUSINESS ACQUISITIONS

Business Combination between RFMD and TriQuint Semiconductor, Inc. ("TriQuint")

Effective January 1, 2015, pursuant to the Merger Agreement, RFMD and TriQuint completed a strategic combination of their respective businesses through the “merger of equals” Business Combination.

As a result of the Business Combination, RFMD and TriQuint have combined complementary product portfolios, featuring power amplifiers (PAs), power management integrated circuits (PMICs), antenna control solutions, switch-based products and premium filters, to deliver a comprehensive portfolio of high-performance mobile solutions. It is expected that the Business Combination will continue to strengthen the combined company’s service to the infrastructure and defense/aerospace industries and enable advanced gallium nitride (GaN) solutions for additional markets and applications. It is also expected that customers will benefit from new scale advantages in manufacturing and research and development, as well as an aggressive roadmap of new products and technologies.

The parties effected the Business Combination by (i) merging a newly-formed direct subsidiary of Qorvo with and into TriQuint, with TriQuint surviving the merger as a wholly owned direct subsidiary of Qorvo (such merger, the “TriQuint Merger”); and (ii) merging a newly-formed direct subsidiary of Qorvo with and into RFMD, with RFMD surviving the merger as a wholly owned direct subsidiary of Qorvo (the “RFMD Merger”).

Pursuant to the terms of the Merger Agreement, at the effective time of the RFMD Merger (the “RFMD Merger Effective Time”), by virtue of the RFMD Merger and without any action on the part of any stockholder, each share of common stock of RFMD, no par value per share (“RFMD Common Stock”), was converted into the right to receive 0.25 of a share of common stock, par value $0.0001 per share, of Qorvo (the exchange ratio of one share of RFMD Common Stock for 0.25 of a share of Qorvo Common Stock, the “RFMD Conversion Ratio”) plus cash in lieu of fractional shares. The Merger Agreement provided that, at the RFMD Merger Effective Time, all RFMD equity awards as of immediately prior to the RFMD Merger Effective Time were assumed by Qorvo, except that such equity awards as were exercisable for or may be settled in shares of RFMD Common Stock became exercisable for or may be settled in shares of Qorvo Common Stock based on the RFMD Conversion Ratio.

Pursuant to the terms of the Merger Agreement, at the effective time of the TriQuint Merger (the “TriQuint Merger Effective Time”), by virtue of the TriQuint Merger and without any action on the part of any stockholder, each share of common stock of TriQuint, $0.001 par value per share (“TriQuint Common Stock”), was converted into the right to receive 0.4187 of a share of Qorvo Common Stock (the exchange ratio of one share of TriQuint Common Stock for 0.4187 of a share of Qorvo Common Stock, the “TriQuint Conversion Ratio” and, together with the RFMD Conversion Ratio, the “Conversion Ratios”) plus cash in lieu of fractional shares. The Merger Agreement provided that, at the TriQuint Merger Effective Time, all TriQuint equity awards as of immediately prior to the TriQuint Merger Effective Time were assumed by Qorvo, except that such equity awards as were exercisable for or may be settled in shares of TriQuint Common Stock became exercisable for or may be settled in shares of Qorvo Common Stock based on the TriQuint Conversion Ratio.

The RFMD Merger Effective Time occurred immediately after the TriQuint Merger Effective Time. At the closing of the transaction, the effect of the application of the Conversion Ratios constituted a one-for-four reverse stock split of the issued and outstanding shares of RFMD Common Stock and TriQuint Common Stock. All share and per share information contained in the accompanying Consolidated Financial Statements and Notes to the Consolidated Financial Statements have been retroactively adjusted to reflect the reverse stock split for all periods presented.

The RFMD Common Stock and the TriQuint Common Stock were voluntarily delisted from the NASDAQ Stock Market in connection with the Business Combination. The Qorvo Common Stock is now trading on the NASDAQ Global Select Market under the ticker symbol “QRVO”.

Based on an evaluation of the provisions of FASB ASC Topic 805, “Business Combinations,” RFMD was determined to be the acquirer for accounting purposes. Under FASB ASC Topic 805, RFMD is treated as having acquired TriQuint in an all-stock transaction for an estimated total purchase price of approximately $5,254.4 million. The calculation of the total purchase price is based on the outstanding shares of TriQuint Common Stock as of the acquisition date multiplied by the exchange ratio of 1.6749, and the resulting shares are then adjusted by the one-for-four reverse stock split and multiplied by the Qorvo split-adjusted share price of $66.36 on the date of acquisition. The purchase price also includes the fair value of replacement equity awards attributable to service prior to the closing of the Business Combination, which is estimated based on the ratio of the service period rendered as of the acquisition date to the total service period.

The estimated total purchase price was preliminarily allocated to TriQuint's assets and liabilities based upon fair values as determined by the Company, as follows (in thousands):



Cash and cash equivalents	$	224,324
Short-term investments	40,371
Accounts receivable	187,058
Inventories	218,433
Prepaid expenses and other assets	84,389
Property and equipment	591,895
Intangible assets (Note 7)	2,394,000
Goodwill	2,036,685
Total assets	5,777,155
Accounts payable and accrued liabilities	(522,788		)
Total purchase price	$	5,254,367

The allocation of the purchase price reflected in the accompanying financial statements is preliminary and is based upon estimates and assumptions that are subject to change within the measurement period (up to one year from the acquisition date pursuant to ASC 805). The measurement period remains open pending the completion of valuation procedures related to the acquired assets and assumed liabilities. The $2,036.7 million allocated to goodwill represents the excess of the purchase price over the fair value of assets acquired and liabilities assumed, which amount has been allocated to the Company's MP operating segment ($1,745.5 million) and IDP operating segment ($291.2 million), and it is not deductible for income tax purposes.

TriQuint's results of operations, which include revenue of $259.5 million and a net loss of $132.5 million, are included in the Company’s Consolidated Statements of Operations for the period of January 1, 2015 through March 28, 2015. The net loss includes adjustments for amortization expense of the acquired intangible assets, inventory step-up, stock-based compensation related to the Business Combination and restructuring expenses.

During fiscal 2015, the Company incurred acquisition costs of $12.2 million and integration costs of $31.3 million associated with the Business Combination. During fiscal 2014, the Company incurred acquisition-related costs of $5.1 million associated with the Business Combination.

The acquisition and integration costs are being expensed as incurred and are presented in the Consolidated Statements of Operations as "Other operating expense."

Pro forma financial information (unaudited)

The following unaudited pro forma consolidated financial information for fiscal years 2015 and 2014 assumes that the acquisition of TriQuint was completed as of March 31, 2013:



	2015		2014
Revenue	$	2,556,045	$	2,037,466
Net income (loss)	30,447		(475,219		)
Basic net income (loss) per common share	$	0.21	$	(3.26	)
Diluted net income (loss) per common share	$	0.20	$	(3.26	)

Pro forma revenue includes adjustments for the purchases by RFMD of various products from TriQuint. These results are not intended to be a projection of future results and do not reflect the actual revenue that might have been achieved by Qorvo. Pro forma net loss income (loss) includes adjustments for amortization expense of acquired intangible assets, stock-based compensation, acquisition-related costs, and an adjustment for income taxes.

These pro forma results have been prepared for comparative purposes only and do not purport to be indicative of the revenue or operating results that would have been achieved had the acquisition actually taken place as of March 31, 2013. In addition, these results are not intended to be a projection of future results and do not reflect synergies that might be achieved from the combined operations.

Acquisition of Amalfi Semiconductor, Inc.

ASSET TRANSFER TRANSACTION	ASSET TRANSFER TRANSACTION During fiscal 2013, the Company entered into an asset transfer agreement with IQE, Inc. ("IQE") under which it transferred its MBE operations (located in Greensboro, N.C.) to IQE. The assets transferred to IQE had a total book value of approximately $24.4 million and included the Company’s leasehold interest in the real property, building and improvements used for the facility and machinery and equipment located in the facility, all of which were written off during the first quarter of fiscal 2013. In addition, the Company wrote-off approximately $1.0 million of IDP-related goodwill as a result of this transaction. In conjunction with the asset transfer agreement, the Company and IQE entered into a wafer supply agreement under which IQE supplies the Company with wafer starting materials. This wafer supply agreement, which is recorded as an intangible asset on the Company’s Consolidated Balance Sheets, provides the Company with competitive wafer pricing through March 31, 2016 (see Note 1 and Note 7).

Goodwill resulting from Business Combination (Note 5)	2,036,685
Balance as of March 28, 2015 (1)	$	2,140,586

(1) As of March 28, 2015, the Company’s goodwill balance of $2,140.6 million was comprised of gross goodwill of $2,762.2 million less accumulated impairment losses and write-offs of $621.6 million.

Effective January 1, 2015, pursuant to the Merger Agreement, RFMD and TriQuint completed the Business Combination, which resulted in goodwill of $2,036.7 million (see Note 5).

Goodwill is allocated to the reporting units that are expected to benefit from the synergies of the business combinations generating the underlying goodwill. As of March 28, 2015, $1,755.7 million and $384.9 million of the Company’s goodwill balance was allocated to its MP reporting unit and IDP reporting unit, respectively.

The following summarizes information regarding the gross carrying amounts and accumulated amortization of intangibles (in thousands):



	March 28, 2015				March 29, 2014

The Business Combination resulted in the recognition of $120.3 million of incremental intangible asset amortization expense during fiscal 2015 (of which $49.6 million was recorded in "Cost of goods sold" and $70.7 million was recorded in "Marketing and selling"). IPRD is not subject to amortization until completion or abandonment of the associated research and development effort. The IPRD acquired in the Business Combination of $470.0 million relates to the MP operating segment ($350.0 million) and the IDP operating segment ($120.0 million), and encompasses a broad technology portfolio of product innovations in RF applications for MP and IDP products. These technologies include a variety of semiconductor processes in GaAs and GaN for power and switching applications and SAW and BAW structures for filter applications. Included in IPRD are continuous improvements in the process for design and manufacturing as well as innovation in fundamental research areas such as materials, simulation and modeling, circuit design, device packaging and test. As of March 28, 2015, IPRD for the MP operating segment was 45% complete with an estimated completion time of approximately 11 months and a remaining cost to complete of approximately $82.0 million. As of March 28, 2015, the IPRD associated with the IDP operating segment was 68% complete with an estimated completion time of approximately 8 months and a remaining cost to complete of approximately $17.0 million. Upon completion of the development, acquired IPRD assets will be transferred to finite-lived intangible assets and amortized over its useful life.

In the fourth quarter of fiscal 2014, the Company initiated a restructuring effort to reduce operating expenses (see Note 11 for further information on the restructuring). As part of this restructuring, the Company discontinued engineering efforts on an in-process research and development project acquired for MP as part of the acquisition of Amalfi and an impairment charge of $11.3 million was recorded in "Other operating expense."

Intangible asset amortization expense was $142.7 million, $28.6 million and $23.1 million in fiscal years 2015, 2014 and 2013, respectively.

The following table provides the Company's estimated future amortization expense based on current amortization periods for the periods indicated (in thousands):

At March 29, 2014, the carrying amount of the equity component of the 2012 Notes and 2014 Notes was $20.0 million and $33.2 million, respectively. The principal amount, unamortized discount, and net carrying value of the liability components of the 2014 Notes were $87.5 million, $(0.2) million and $87.3 million, respectively, as of March 29, 2014. The effective interest rates for the liability components were 7.3% for the 2012 Notes during fiscal 2013 and 7.2% for the 2014 Notes during fiscal years 2014 and 2013. Interest expense on the liability component of the Notes was $0.9 million and $1.0 million during fiscal years 2014 and 2013, respectively, and amortization of the discount was $5.2 million and $5.8 million during fiscal years 2014 and 2013, respectively. At March 29, 2014, the 2014 Notes had a fair value on the PORTAL Market of $88.7 million, compared to a carrying value of $87.3 million. Credit Agreement In March 2013, the Company and certain material domestic subsidiaries of the Company entered into a four-year senior credit facility with Bank of America, N.A., as Administrative Agent and a lender, and a syndicate of other lenders (the “Credit Facility”). The Credit Facility included a $125.0 million revolving credit facility, which included a $5.0 million sublimit for the issuance of standby letters of credit and a $5.0 million sublimit for swingline loans. The Company could request, at any time and from time to time, that the revolving credit facility be increased by an amount not to exceed $50.0 million. On March 26, 2015, the Company terminated its Credit Facility. No borrowings were ever made under the Credit Facility and no early termination penalty was incurred by the Company in connection with such termination. The Credit Facility was terminated in anticipation of the Company entering into a new, larger revolving credit facility, which the Company entered into on April 7, 2015 (see Note 18).

In total, the Company contributed $6.5 million, $5.5 million and $5.4 million to its domestic and foreign defined contribution plans during fiscal years 2015, 2014 and 2013, respectively. Defined Benefit Pension Plans As a result of the Business Combination, the Company maintains two qualified defined benefit pension plans for its subsidiaries located in Germany. One of the plans is funded through a self-paid reinsurance program with $3.2 million of assets valued as on March 28, 2015. Assets of the funded plan are included in "Other non-current assets" in the Consolidated Balance Sheets. The net periodic benefit obligations of both plans was $12.2 million and $5.5 million as of March 28, 2015 and March 29, 2014, respectively, which is included in “Accrued liabilities” and “Other long-term liabilities” in the Consolidated Balance Sheets. The assumptions used in calculating the benefit obligations for the plans are dependent on the local economic conditions and were measured as of March 28, 2015 and March 29, 2014. The net periodic benefit costs were approximately $0.4 million for fiscal year 2015 and $0.3 million for fiscal years 2014 and 2013.

The Plan provides eligible participants the opportunity to defer and invest a specified percentage of their cash compensation. The deferred compensation plan is a non-qualified plan that is maintained in a rabbi trust. The amount of compensation to be deferred by each participant is based on their own elections and is adjusted for any investment changes that the participant directs. The deferred compensation obligation and the fair value of the investments held in the rabbi trust were $8.6 million as of March 28, 2015. The $5.3 million current portion and $3.3 million non-current portion of the deferred compensation obligation and fair value of the assets held in the rabbi trust are included in "Other current assets," "Accrued liabilities," "Other non-current assets" and "Other long-term liabilities" in the Consolidated Balance Sheets.

Commitments and Contingencies Disclosure [Abstract]

COMMITMENTS AND CONTINGENT LIABILITIES

The Company leases certain of its corporate, wafer fabrication and other facilities from multiple third-party real estate developers. The remaining terms of these operating leases range from less than one year to 13 years. Several have renewal options of up to two, ten-year periods and several also include standard inflation escalation terms. Several also include rent escalation, rent holidays, and leasehold improvement incentives which are recognized to expense on a straight-line basis. The amortization period of leasehold improvements made either at the inception of the lease or during the lease term is amortized over the lesser of the remaining life of the lease term (including renewals that are reasonably assured) or the useful life of the asset. The Company also leases various machinery and equipment and office equipment under non-cancelable operating leases. The remaining terms of these operating leases range from less than one year to approximately three years. As of March 28, 2015, the total future minimum lease payments were approximately $59.8 million related to facility operating leases and approximately $0.1 million related to equipment operating leases.

Minimum future lease payments under non-cancelable operating leases as of March 28, 2015, are as follows (in thousands):



Fiscal Year
2016	$	13,195
2017	10,708
2018	8,887
2019	6,255
2020	4,160
Thereafter	16,734
Total minimum payment	$	59,939

Rent expense under operating leases, including facilities and equipment, was approximately $12.1 million, $10.7 million, and $10.1 million for fiscal years 2015, 2014 and 2013, respectively.

Legal Matters

The Company accrues a liability for legal contingencies when it believes that it is both probable that a liability has been incurred and that it can reasonably estimate the amount of the loss. The Company reviews these accruals and adjusts them to reflect ongoing negotiations, settlements, rulings, advice of legal counsel and other relevant information. To the extent new information is obtained and the Company's views on the probable outcomes of claims, suits, assessments, investigations or legal proceedings change, changes in the Company's accrued liabilities would be recorded in the period in which such determination is made.

The Company is involved in various legal proceedings and claims that have arisen in the ordinary course of its business that have not been fully adjudicated. These actions, when finally concluded and determined, will not, in the opinion of management, have a material adverse effect upon the Company’s consolidated financial position or results of operations.

Restructuring	12 Months Ended

Restructuring and Related Activities [Abstract]
RESTRUCTURING	RESTRUCTURING During fiscal 2015, the Company recorded restructuring expenses in "Other operating expense" of approximately $10.9 million as a result of the Business Combination (see Note 5), primarily related to employee termination benefits. The restructuring obligations (relating primarily to employee termination benefits) totaling $6.4 million as of March 28, 2015, are included in “Accrued liabilities” in the Consolidated Balance Sheets. During fiscal 2014, the Company recorded $11.1 million of restructuring expenses, related to (1) efforts initiated to achieve manufacturing efficiencies, (2) efforts initiated to reduce operating expenses, (3) expenses associated with the sale of its GaAs semiconductor manufacturing facility in the U.K., and (4) expenses associated with the 2009 economic restructuring efforts. During fiscal 2014, the Company initiated restructuring efforts to achieve manufacturing efficiencies. The Company recorded restructuring expenses in “Other operating expense” of approximately $4.1 million, in fiscal 2014, primarily related to employee termination benefits. This restructuring initiative was completed during fiscal 2014. In the fourth quarter of fiscal 2014, the Company initiated another restructuring to reduce operating expenses. The Company recorded restructuring expenses in “Other operating expense” of approximately $1.3 million and $2.5 million, in fiscal years 2015 and 2014, respectively, primarily related to employee termination benefits. As part of this restructuring, the Company discontinued engineering efforts related to an IPRD project and impaired the intangible asset in the amount of $11.3 million, which is also recorded in “Other operating expense” (see Note 7). This restructuring initiative was completed during fiscal 2015. In March 2013, the Company announced that it would phase out manufacturing in its Newton Aycliffe, U.K.-based GaAs facility and transition the remaining product demand from that facility to its GaAs manufacturing facility in Greensboro, N.C. During the second quarter of fiscal 2014, the Company sold its U.K.-based GaAs facility to Compound Photonics. The Company recorded restructuring charges in “Other operating expense” of approximately $4.4 million and $0.8 million in fiscal years 2014 and 2013, respectively, primarily related to impaired property, plant and equipment and employee termination benefits. This restructuring initiative was completed during fiscal 2014. In fiscal 2009, the Company initiated a restructuring to reduce manufacturing capacity and costs and operating expenses due primarily to lower demand for its products resulting from the global economic slowdown. The restructuring decreased the Company’s workforce and resulted in the impairment of certain property and equipment, among other charges. The Company recorded restructuring charges in “Other operating expense” of approximately $0.2 million, $0.1 million and $0.2 million in fiscal years 2015, 2014 and 2013, respectively, related to lease and other contract termination costs. The current and long-term restructuring obligations (relating primarily to lease obligations) totaling $3.5 million and $3.9 million as of March 28, 2015 and March 29, 2014, respectively, are included in “Accrued liabilities” and “Other long-term liabilities” in the Consolidated Balance Sheets. As of March 28, 2015, the restructuring associated with the adverse macroeconomic business environment is substantially complete. The Company expects to record approximately $0.7 million of additional restructuring charges primarily associated with ongoing expenses related to exited leased facilities.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the basis used for income tax purposes. The deferred income tax assets and liabilities are measured in each taxing jurisdiction using the enacted tax rates and laws that will be in effect when the differences are expected to reverse.

Significant components of the Company’s net deferred income taxes are as follows (in thousands):

The Company has recorded a $13.8 million and a $143.3 million valuation allowance against the U.S. deferred tax assets and small net deferred tax assets at several foreign subsidiaries as of March 28, 2015 and March 29, 2014, respectively. These valuation allowances were established based upon management's opinion that it is more likely than not that the benefit of these deferred tax assets may not be realized. Realization is dependent upon generating future income in the taxing jurisdictions in which the operating loss carryovers, credit carryovers, depreciable tax basis and other tax deferred assets exist. It is management's intent to evaluate the realizability of these deferred tax assets on a quarterly basis.

The valuation allowance against net deferred tax assets increased in fiscal 2013 by $51.5 million from the $112.7 million balance as of the end of fiscal 2012. The change was comprised of $12.0 million established during the fiscal year related to the U.K., $10.8 million related to the Amalfi acquisition, and a $28.7 million increase related to changes in domestic net deferred tax assets during the fiscal year. The U.K. valuation allowance was recorded as a result of the decision, announced in March 2013, to phase out manufacturing at the Newton Aycliffe U.K. facility. Consequently, the Company determined that this represented significant negative evidence, and that it was no longer “more likely than not” that any U.K. deferred tax assets remaining at the end of fiscal 2014 would ultimately be realized.

The valuation allowance against net deferred tax assets decreased in fiscal 2014 by $20.9 million. The decrease was comprised of the reversal of the $12.0 million U.K. valuation allowance established during fiscal 2013 and $15.1 million related to deferred tax assets used against deferred intercompany profits, offset by increases related to a $3.4 million adjustment in the net operating losses acquired in the Amalfi acquisition and $2.8 million for other changes in net deferred tax assets for domestic and for other foreign subsidiaries during the fiscal year. The U.K. valuation allowance was reversed in connection with the sale of the U.K. manufacturing facility in fiscal 2014 and the write-off of the remaining U.K. deferred tax assets.

The valuation allowance against net deferred tax assets decreased in fiscal 2015 by $129.5 million. The decrease was comprised of $135.7 million related to domestic deferred tax assets for which realization is now more likely than not with the increase in domestic deferred tax liabilities related to domestic amortizable intangible assets arising in connection with the Business Combination and other changes in the net deferred tax assets for foreign subsidiaries during the fiscal year, offset by an increase of $6.2 million related to deferred tax assets acquired in the Business Combination that are not more likely than not of being realized. As of the end of fiscal 2015, a $0.2 million valuation allowance remained against foreign net deferred tax assets and a $13.6 million valuation allowance remained against domestic deferred tax assets as it is more likely than not that the related deferred tax assets will not be realized, effectively increasing the domestic net deferred tax liabilities.

As of March 28, 2015, the Company had federal loss carryovers of approximately $202.3 million that expire in fiscal years 2016 to 2035 if unused and state losses of approximately $184.9 million that expire in fiscal years 2016 to 2035 if unused. Federal research credits of $79.9 million, federal foreign tax credits of $1.7 million, and state credits of $45.9 million may expire in fiscal years 2018 to 2035, 2016 to 2035, and 2016 to 2030, respectively. Federal alternative minimum tax credits of $3.2 million will carry forward indefinitely. Included in the amounts above are certain net operating losses and other tax attribute assets acquired in conjunction with acquisitions in the current and prior years. The utilization of acquired domestic assets is subject to certain annual limitations as required under Internal Revenue Code Section 382 and similar state income tax provisions.

The Company has continued to expand its operations and increase its investments in numerous international jurisdictions. These activities expose the Company to taxation in multiple foreign jurisdictions. It is management's opinion that current and future undistributed foreign earnings will be permanently reinvested. Accordingly, no provision for U.S. federal and state income taxes has been made thereon. It is not practical to estimate the additional tax that would be incurred, if any, if the permanently reinvested earnings were repatriated. At March 28, 2015, the Company has not provided U.S. taxes on approximately $453.6 million of undistributed earnings of foreign subsidiaries that have been indefinitely reinvested outside the U.S.

In the Business Combination, the Company acquired foreign subsidiaries with tax holiday agreements in Costa Rica and Singapore. These tax holiday agreements have varying rates and expire in March 2024 and December 2021, respectively. Incentives from these countries are subject to the Company meeting certain employment and investment requirements. Income tax expense was decreased in fiscal 2015 by $19.1 million (approximately $0.21 per basic and diluted share impact) as a result of these agreements.

The Company’s gross unrecognized tax benefits totaled $59.4 million as of March 28, 2015, $39.4 million as of March 29, 2014, and $37.9 million as of March 30, 2013. Of these amounts, $55.0 million (net of federal benefit of state taxes), $30.9 million (net of federal benefit of state taxes), and $29.7 million (net of federal benefit of state taxes) as of March 28, 2015, March 29, 2014, March 30, 2013, respectively, represent the amounts of unrecognized tax benefits that, if recognized, would impact the effective tax rate in each of the fiscal years.

A reconciliation of the fiscal 2013 through fiscal 2015 beginning and ending amount of gross unrecognized tax benefits is as follows (in thousands):



	Fiscal Year
	2015			2014			2013
Beginning balance	$	39,423		$	37,917		$	31,727
Additions based on positions related to current year	1,246			2,181			2,209
Additions for tax positions in prior years	23,986			229			4,780
Reductions for tax positions in prior years	(5,258		)	(904		)	(482		)
Expiration of statute of limitations	—			—			(317		)
Ending balance	$	59,397		$	39,423		$	37,917

Of the fiscal 2015 and 2013 additions to tax positions in prior years, $17.1 million and $4.4 million, respectively, were assumed by the Company in the Business Combination and the Amalfi acquisition and relates to positions taken on tax returns for pre-acquisition periods.

It is the Company’s policy to recognize interest and penalties related to uncertain tax positions as a component of income tax expense. During fiscal years 2015, 2014 and 2013, the Company recognized $1.2 million, $0.9 million, and $0.7 million, respectively, of interest and penalties related to uncertain tax positions. Accrued interest and penalties related to unrecognized tax benefits totaled $3.4 million, $2.3 million, and $1.3 million as of March 28, 2015, March 29, 2014 and March 30, 2013, respectively.

Within the next 12 months, the Company believes it is reasonably possible that only a minimal amount of gross unrecognized tax benefits will be reduced as a result of reductions for temporary tax positions taken in prior years.

RFMD's and TriQuint's federal, North Carolina, and California tax returns for fiscal 2012 and calendar 2011, respectively, and subsequent tax years remain open for examination. Returns for calendar years 2005 through 2007 have been examined by the German taxing authorities and returns for subsequent fiscal tax years remain open for examination. Other material jurisdictions that are subject to examination by tax authorities are the U.K. (fiscal 2013 through present), Singapore (calendar 2011 through present) and China (calendar year 2004 through present). Tax attributes (including net operating loss and credit carryovers) arising in earlier fiscal years remain open to adjustment.

NET INCOME (LOSS) PER SHARE

Pursuant to the terms of the Merger Agreement, effective January 1, 2015, the Company effected a one-for-four reverse stock split of the Company's issued and outstanding shares of common stock. In accordance with Staff Accounting Bulletin Topic 4.C, all share and per share information contained in the accompanying Consolidated Financial Statements, Notes to the Consolidated Financial Statements and Management's Discussion and Analysis of Financial Condition and Results of Operation (included in Item 7 of this report) have been retroactively adjusted to reflect the reverse stock split for all periods presented. See Note 5 for a further discussion of the Business Combination.

The following table sets forth the computation of basic and diluted net income (loss) per share (in thousands, except per share data):



	For Fiscal Year

Diluted net income (loss) per share	$	2.11	$	0.18	$	(0.76	)

In the computation of diluted net income per share for fiscal years 2015 and 2014, less than 0.1 million and 1.8 million shares were excluded because the exercise price of the options was greater than the average market price of the underlying common stock and the effect of their inclusion would have been anti-dilutive. In the computation of diluted net loss per share for fiscal 2013, all outstanding stock-based awards were excluded because the effect of their inclusion would have been anti-dilutive.

The computation of diluted net income (loss) per share does not assume the conversion of the Notes. The 2014 Notes became due on April 15, 2014, and the remaining principal balance of $87.5 million plus interest of $0.4 million was paid with cash on hand. The 2012 Notes became due on April 15, 2012, and the remaining principal balance of $26.5 million was paid with cash on hand.

Employee Stock Purchase Plan - Qorvo, Inc.

Effective upon closing of the Business Combination, the Company assumed the TriQuint Employee Stock Purchase Plan ("ESPP"), which is intended to qualify as an “employee stock purchase plan” under Section 423 of the Internal Revenue Code. All regular full-time employees of the Company (including officers) and all other employees who meet the eligibility requirements of the plan may participate in the ESPP. The ESPP provides eligible employees an opportunity to acquire the Company’s common stock at 85% of the lower of the closing price per share of the Company’s common stock on the first or last day of each six-month purchase period. At March 28, 2015, 6.2 million shares were available for future issuance under this plan. The Company makes no cash contributions to the ESPP, but bears the expenses of its administration. The Company issued 0.1 million shares under the ESPP in fiscal 2015.

For fiscal years 2015, 2014 and 2013, the primary stock-based awards and their general terms and conditions are as follows:

Stock options are granted to employees with an exercise price equal to the market price of the Company’s stock at the date of grant, generally vest over a four-year period from the grant date, and generally expire 10 years from the grant date. Restricted stock units granted by the Company in fiscal years 2015, 2014 and 2013 are either service-based, performance and service-based, or based on total stockholder return. Service-based restricted stock units generally vest over a four-year period from the grant date. Performance and service-based restricted stock units are earned based on Company performance of stated metrics generally during the fiscal year and, if earned, vest one-half when earned and the balance over two years. Restricted stock units based on total stockholder return are earned based upon total stockholder return of the Company in comparison to the total stockholder return of a benchmark index and can be earned over one, two and three-year performance periods. Under the 2012 Plan for fiscal years 2014 and 2013 and the 2006 Directors’ Stock Option Plan for fiscal 2012, stock options granted to non-employee directors (other than initial options, as described below) had an exercise price equal to the fair market value of the Company’s stock at the date of grant, vested immediately upon grant and expire 10 years from the grant date. Each non-employee director who was first elected or appointed to the Board of Directors during such period received an initial option covering shares with a value set by the Board of Directors at an exercise price equal to the fair market value of the Company’s stock at the date of grant, which vested over a two-year period from the grant date and expired 10 years from the grant date. At the director’s option, the director could elect to receive all or part of the initial grant in restricted stock units. Thereafter, each non-employee director was eligible to receive an annual option or, if he so chose, an annual grant of restricted stock units.

The options and restricted stock units granted to certain officers of the Company generally will, in the event of the officer's termination other than for cause and subject to the officer executing certain agreements in favor of the Company, continue to vest pursuant to the same vesting schedule as if the officer had remained an employee of the Company and as a result, these awards are expensed at grant date. In fiscal 2015, stock-based compensation of $11.7 million was recognized upon the grant of 0.4 million options and restricted share units to certain officers of the Company.

Stock-Based Compensation

Under ASC 718, stock-based compensation cost is measured at the grant date, based on the estimated fair value of the award using an option pricing model for stock options (Black-Scholes) and market price for restricted stock units, and is recognized as expense over the employee's requisite service period. ASC 718 covers a wide range of stock-based compensation arrangements including stock options, restricted share plans, performance-based awards, share appreciation rights and employee stock purchase plans.

Total pre-tax stock-based compensation expense recognized in the Consolidated Statements of Operations was $64.9 million for fiscal 2015, net of expense capitalized into inventory. For fiscal years 2014 and 2013, the total pre-tax stock-based compensation expense recognized was $29.9 million and $30.8 million, respectively, net of expense capitalized into inventory.

A summary of activity of the Company’s director and employee stock option plans follows:



	Shares (in thousands)	Weighted- Average Exercise Price		Weighted-Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (in thousands)
Outstanding as of March 29, 2014	1,753	$	23.08
Assumed	8,036	$	18.35
Granted	63	$	56.80
Exercised	(2,037)	$	19.33
Canceled	(23)	$	27.49
Forfeited	(28)	$	19.76
Outstanding as of March 28, 2015	7,764	$	18.61	6.08	$	471,040
Vested and expected to vest as of March 28, 2015	7,447	$	18.68	6.01	$	451,327
Options exercisable as of March 28, 2015	4,514	$	18.55	5.05	$	274,121

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value, based upon the Company’s closing stock price of $79.28 as of March 28, 2015, that would have been received by the option holders had all option holders with in-the-money options exercised their options as of that date.

The fair value of each option award is estimated on the date of grant using a Black-Scholes option-pricing model based on the assumptions noted in the following tables:



	Fiscal Year
	2015			2014			2013
Expected volatility	40.6		%	43.2		%	51.6		%
Expected dividend yield	0.0		%	0.0		%	0.0		%
Expected term (in years)	5.6			5.5			5.5
Risk-free interest rate	1.7		%	1.4		%	0.8		%
Weighted-average grant-date fair value of options granted during the period	$	22.49		$	2.08		$	1.80

The fair value of TriQuint converted grants was estimated on the date of the Business Combination using a Black-Scholes multiple option-pricing model with the following weighted-average assumptions:



	At January 1, 2015 TriQuint Converted Grants
Expected life of option	0-5 years
Risk-free interest rate	0.03-1.65%
Expected volatility of stock	42.9%
Expected dividend yield	None

The total intrinsic value of options exercised during fiscal 2015, was $83.7 million. For fiscal years 2014 and 2013, the total intrinsic value of options exercised was $3.1 million and $0.5 million, respectively.

Cash received from the exercise of stock options and from participation in the employee stock purchase plan (excluding accrued unremitted employee funds of approximately $4.0 million) was approximately $42.1 million for fiscal 2015 and is reflected in cash flows from financing activities in the Consolidated Statements of Cash Flows. The Company settles employee stock options with newly issued shares of the Company's common stock.

The Company used the implied volatility of market-traded options on the Company’s common stock for the expected volatility assumption input to the Black-Scholes option-pricing model, consistent with the guidance in ASC 718. The selection of implied volatility data to estimate expected volatility was based upon the availability of actively-traded options on the Company’s common stock and the Company’s assessment that implied volatility is more representative of future common stock price trends than historical volatility.

The dividend yield assumption is based on the Company’s history and expectation of future dividend payouts and may be subject to change in the future. The Company has never paid a dividend.

The expected life of employee stock options represents the weighted-average period that the stock options are expected to remain outstanding. The Company’s method of calculating the expected term of an option is based on the assumption that all outstanding options will be exercised at the midpoint of the current date and full contractual term, combined with the average life of all options that have been exercised or canceled. The Company believes that this method provides a better estimate of the future expected life based on analysis of historical exercise behavioral data.

The risk-free interest rate assumption is based upon observed interest rates appropriate for the terms of the Company’s employee stock options.

ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Based upon historical pre-vesting forfeiture experience, the Company assumed an annualized forfeiture rate of 1.2% for both stock options and restricted stock units.

The following activity has occurred with respect to restricted stock unit awards:



	Shares (in thousands)	Weighted-Average Grant-Date Fair Value
Balance at March 29, 2014	2,298	$	19.44
Granted	1,166	45.61
Assumed	599	66.36
Vested	(1,806)	26.96
Forfeited	(55)	26.75
Balance at March 28, 2015	2,202	$	34.29

As of March 28, 2015, total remaining unearned compensation cost related to nonvested restricted stock units was $153.0 million, which will be amortized over the weighted-average remaining service period of approximately 1.3 years.

The total fair value of restricted stock units that vested during fiscal 2015 was $93.5 million, based upon the fair market value of the Company’s common stock on the vesting date. For fiscal years 2014 and 2013, the total fair value of restricted stock units that vested was $30.0 million and $21.0 million, respectively.

Operating Segment and Geographical Information

Segment Reporting [Abstract]

OPERATING SEGMENT INFORMATION

OPERATING SEGMENT AND GEOGRAPHIC INFORMATION

The Company's operating segments as of March 28, 2015 are Mobile Products (MP) and Infrastructure and Defense Products (IDP). In the fourth quarter of fiscal 2015, the Company renamed its reportable segments from Cellular Products Group (CPG) to MP, and Multi-Market Products Group (MPG) to IDP, as a result of the Business Combination. Additionally, the CODM elected to discontinue reporting Compound Semiconductor Group (CSG) as an operating segment.

MP is a leading global supplier of RF solutions that perform various functions in the increasingly complex cellular radio front end section of smartphones and other cellular devices. These RF solutions are required in fourth generation (“4G”) data-centric devices operating under Long-Term Evolution (“LTE”) and other 4G networks, as well as third generation (“3G”) and second generation (“2G”) mobile devices. These solutions include complete RF front end modules that combine high-performance filters, power amplifiers (“PAs”) and switches, PA modules, transmit modules, antenna control solutions, antenna switch modules, switch filter modules, switch duplexer modules and envelope tracking power management devices. MP supplies its broad portfolio of RF solutions into a variety of mobile devices, including smartphones, handsets, notebook computers, wearables and tablets.

IDP is a leading global supplier of a broad array of RF solutions to wireless network infrastructure, defense and aerospace markets and short-range connectivity applications for commercial, consumer, industrial and automotive markets. Infrastructure applications include 4G LTE and 3G base station deployments, WiFi infrastructure, microwave point-to-point radio and optical network links, and CATV wireline infrastructure. Defense and aerospace applications, which require extreme precision, reliability, durability and supply assurance, include a variety of advanced systems, such as active phased array radar, electronic warfare and various communications applications. Industrial and automotive applications include energy management, private mobile radio, satellite radio and test and measurement equipment. The Company's IDP products include high power GaAs and GaN PAs, low noise amplifiers, switches, fixed frequency and voltage-controlled oscillators, filters, attenuators, modulators, driver and transimpedance amplifiers and various multichip and hybrid assemblies.

As of March 28, 2015, MP and IDP are separate reportable segments based on the organizational structure and information reviewed by the Company’s Chief Executive Officer, who is the Company’s chief operating decision maker (or CODM), and are managed separately based on the end markets and applications they support. The CODM allocates resources and assesses the performance of each operating segment primarily based on non-GAAP operating income (loss) and non-GAAP operating income (loss) as a percentage of revenue.

The “All other” category includes operating expenses such as stock-based compensation, amortization of purchased intangible assets, acquired inventory step-up and revaluation, acquisition and integration related costs, impairment of intangible asset, loss on asset transfer transaction, intellectual property rights (IPR) litigation costs, the inventory revaluation resulting from the transfer of the Company's molecular beam epitaxy (“MBE”) operations, restructuring and disposal costs, certain consulting costs, and other miscellaneous corporate overhead expenses that the Company does not allocate to its reportable segments because these expenses are not included in the segment operating performance measures evaluated by the Company’s CODM. The CODM does not evaluate operating segments using discrete asset information. The Company’s operating segments do not record inter-company revenue. The Company does not allocate gains and losses from equity investments, interest and other income, or taxes to operating segments. Except as discussed above regarding the “All other” category, the Company’s accounting policies for segment reporting are the same as for the Company as a whole.

The following tables present details of the Company’s reportable segments and a reconciliation of the “All other” category (in thousands):

Sales, for geographic disclosure purposes, are based on the “sold to” address of the customer. The “sold to” address is not always an accurate representation of the location of final consumption of the Company’s components. Of the Company’s total revenue for fiscal 2015, approximately 49% ($841.0 million) was from customers in China and 19% ($332.5 million) from customers in Taiwan. Long-lived tangible assets primarily include property and equipment and at March 28, 2015, approximately $126.5 million (or 14%) of the Company’s total property and equipment was located in China.

Subsequent Event [Line Items]
Subsequent Events [Text Block]	SUBSEQUENT EVENTS On April 7, 2015, the Company and certain material domestic subsidiaries of the Company (the “Guarantors”) entered into a five-year unsecured senior credit facility with Bank of America, N.A., as administrative agent (in such capacity, the “Administrative Agent”), swing line lender, and L/C issuer, and a syndicate of lenders (the “Credit Agreement”). The Credit Agreement includes a $300 million revolving credit facility, which includes a $25 million sublimit for the issuance of standby letters of credit and a $10 million sublimit for swingline loans. The Company may request, at any time and from time to time, that the revolving credit facility be increased by an amount not to exceed $150 million. The revolving credit facility is available to finance working capital, capital expenditures and other lawful corporate purposes. The Company’s obligations under the Credit Agreement are jointly and severally guaranteed by the Guarantors. The Company currently has no outstanding amounts under the Credit Agreement. At the Company’s option, loans under the Credit Agreement shall bear interest at (i) the Applicable Rate (as defined in the Credit Agreement) plus the Eurodollar Rate (as defined in the Credit Agreement) or (ii) the Applicable Rate plus a rate equal to the highest of (a) the federal funds rate plus 0.50%, (b) the prime rate of the Administrative Agent, or (c) the Eurodollar Rate plus 1.0% (the “Base Rate”). All swingline loans will bear interest at a rate equal to the Applicable Rate plus the Base Rate. The Eurodollar Rate is the rate per annum equal to the London Interbank Offered Rate, as published by Bloomberg, for dollar deposits for interest periods of one, two, three or six months, as selected by the Company. The Applicable Rate for Eurodollar Rate loans ranges from 1.50% per annum to 2.00% per annum. The Applicable Rate for Base Rate loans ranges from 0.50% per annum to 1.00% per annum. Interest for Eurodollar Rate loans shall be payable at the end of each applicable interest period or at three-month intervals, if such interest period exceeds three months. Interest for Base Rate loans shall be payable quarterly in arrears. The Company will pay a letter of credit fee equal to the Applicable Rate multiplied by the daily amount available to be drawn under any letter of credit, a fronting fee, and any customary documentary and processing charges for any letter of credit issued under the Credit Agreement. The Credit Agreement contains various conditions, covenants and representations with which the Company must be in compliance in order to borrow funds and to avoid an event of default, including financial covenants that the Company must maintain a consolidated leverage ratio not to exceed 2.50 to 1.0 as of the end of any fiscal quarter of the Company and a consolidated interest coverage ratio not to be less than 3.00 to 1.0 as of the end of any fiscal quarter of the Company. The Credit Agreement also contains customary events of default, and the occurrence of an event of default will increase the applicable rate of interest by 2.00% and could result in the termination of commitments under the revolving credit facility, the declaration that all outstanding loans are due and payable in whole or in part and the requirement of cash collateral deposits in respect of outstanding letters of credit. Outstanding amounts are due in full on the maturity date of April 7, 2020 (with amounts borrowed under the swingline option due in full no later than ten business days after such loan is made).

The Company and Its Significant Accounting Policies (Policies)	12 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The results of operations, assets and liabilities associated with the business combination with TriQuint have been included in the Company's financial statements from the acquisition date of January 1, 2015 (see Note 5). The results of operations, assets and liabilities associated with the acquisition of Amalfi Semiconductor, Inc. (“Amalfi”) have been included in the Company's financial statements from the acquisition date of November 9, 2012 (see Note 5).
Accounting Periods	Accounting Periods The Company uses a 52- or 53-week fiscal year ending on the Saturday closest to March 31 of each year. The most recent three fiscal years ended on March 28, 2015, March 29, 2014, and March 30, 2013. Fiscal years 2015, 2014 and 2013 were 52-week years.
Use of Estimates	Use of Estimates The preparation of the Consolidated Financial Statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The actual results that the Company experiences may differ materially from its estimates. The Company makes estimates for the returns reserve, rebates, allowance for doubtful accounts, inventory valuation including reserves, warranty reserves, income tax valuation, current and deferred income taxes, uncertain tax positions, non-marketable equity investments, other-than-temporary impairments of investments, goodwill, long-lived assets and other financial statement amounts on a regular basis and makes adjustments based on historical experiences and expected future conditions. Accounting estimates require difficult and subjective judgments and actual results may differ from the Company’s estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of demand deposit accounts, money market funds, and other temporary, highly-liquid investments with original maturities of three months or less when purchased.
Investments	Investments Investments available-for-sale at March 28, 2015 consisted of U.S. government/agency securities, corporate debt, marketable equity securities, auction rate securities (ARS), and money market funds. Investments available-for-sale at March 29, 2014 consisted of U.S. government/agency securities, ARS, and money market funds. Available-for-sale investments with an original maturity date greater than approximately three months and less than one year are classified as current investments. Available-for-sale investments with an original maturity date exceeding one year are classified as long-term. Available-for-sale securities are carried at fair value with the unrealized gains and losses, net of tax, reported in "Other comprehensive income (loss)." The cost of securities sold is based on the specific identification method and any realized gain or loss is included in “Other (expense) income.” The amortized cost of available-for-sale securities is adjusted for amortization of premium and accretion of discounts, which are included as a portion of interest. The Company assesses individual investments for impairment quarterly. Investments are impaired when the fair value is less than the amortized cost. If an investment is impaired, the Company evaluates whether the impairment is other-than-temporary. A debt investment impairment is considered other-than-temporary if (i) the Company intends to sell the security, (ii) it is more likely than not that the Company will be required to sell the security before recovery of the entire amortized cost basis, or (iii) the Company does not expect to recover the entire amortized cost basis of the security (a credit loss). Other-than-temporary declines in the Company's debt securities are recognized as a loss in the statement of operations if due to credit loss; all other losses on debt securities are recorded in "Other comprehensive income (loss)." The previous amortized cost basis less the other-than-temporary impairment becomes the new cost basis and is not adjusted for subsequent recoveries in fair value.
Inventories	Inventories Inventories are stated at the lower of cost or market determined using the average cost method. The Company’s business is subject to the risk of technological and design changes. The Company evaluates inventory levels quarterly against sales forecasts on a product family basis to evaluate its overall inventory risk. Reserves are adjusted to reflect inventory values in excess of forecasted sales which include management's analysis and assessment of overall inventory risk. In the event the Company sells inventory that had been covered by a specific inventory reserve, the sale is recorded at the actual selling price and the related cost of goods sold is recorded at the full inventory cost, net of the reserve. Abnormal production levels are charged to the income statement in the period incurred rather than as a portion of inventory cost.
Product Warranty	Product Warranty The Company generally sells products with a limited warranty on product quality. The Company accrues for known warranty issues if a loss is probable and can be reasonably estimated, and accrues for estimated incurred but unidentified issues based on historical activity. The accrual and the related expense for known product warranty issues were not significant during the periods presented. Due to product testing and the short time typically between product shipment and the detection and correction of product failures and the historical rate of losses, the accrual and related expense for estimated incurred but unidentified issues were not significant during the periods presented.
Property and Equipment	Property and Equipment Property and equipment are stated at cost, less accumulated depreciation. Depreciation of property and equipment is computed using the straight-line method over the estimated useful lives of the assets, ranging from one year to 39 years. The Company’s assets acquired under capital leases and leasehold improvements are amortized over the lesser of the asset life or lease term (which is reasonably assured) and included in depreciation. The Company performs a review if facts and circumstances indicate that the carrying amount of assets may not be recoverable or that the useful life is shorter than had originally been estimated. The Company assesses the recoverability of the assets held for use by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining estimated useful lives against their respective carrying amounts. Impairment, if any, is based on the excess of the carrying amount over the fair value of those assets. If the Company determines that the useful lives are shorter than the Company had originally estimated, the net book value of the assets is depreciated over the newly determined remaining useful lives. The Company identifies property and equipment as “held for sale” based on the current expectation that, more likely than not, an asset or asset group will be sold or otherwise disposed. The held for sale assets cease depreciation once the assets are classified to the held for sale category at the lesser of their carrying value or their fair market value less costs to sell. The Company capitalizes the portion of the interest expense related to certain assets that are not ready for their intended use and this amount is depreciated over the estimated useful lives of the qualified assets. The Company additionally records capital-related government grants earned as a reduction to property and equipment and depreciates such grants over the estimated useful lives of the associated assets.
Other Receivables	Other Receivables The Company records miscellaneous non-product receivables that are collectible within 12 months in “Other receivables,” such as value-added tax receivables ($15.2 million as of March 28, 2015 and $10.1 million as of March 29, 2014, which are reported on a net basis), precious metal reclaims submitted for payment, interest receivables and other miscellaneous items.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill is recorded when the purchase price paid for a business exceeds the estimated fair value of the net identified tangible and intangible assets acquired. Intangibles are recorded when such assets are acquired by purchase or license. The value of the Company's intangibles, including goodwill, could be impacted by future adverse changes such as: (i) any future declines in the Company's operating results; (ii) a decline in the value of technology company stocks, including the value of the Company's common stock; (iii) a prolonged or more significant slowdown in the worldwide economy or the semiconductor industry; or (iv) failure to meet the performance projections included in the Company's forecasts of future operating results. Goodwill and Other Intangible Assets with Indefinite Lives The Company has determined that its reporting units as of fiscal 2015 are MP and IDP for purposes of allocating and testing goodwill. In evaluating its reporting units, the Company first considers its operating segments and related components in accordance with FASB guidance. Goodwill is allocated to the reporting units that are expected to benefit from the synergies of the business combinations generating the underlying goodwill. As of March 28, 2015, the Company's goodwill balance of $2,140.6 million is allocated between its MP and IDP reporting units. The Company accounts for goodwill and indefinite-lived intangible assets in accordance with the FASB's authoritative guidance, which requires that they be tested annually for impairment or earlier if facts and circumstances indicate that they may be impaired. The Company performs its annual impairment test for goodwill and indefinite-lived intangible assets on the first day of the fourth quarter in each fiscal year. Indefinite-lived intangible assets consists of in-process research and development ("IPRD"). The Company has the option to perform a qualitative assessment (commonly referred to as "step zero") to determine whether further quantitative analysis for impairment of goodwill or indefinite-lived intangible assets is necessary. In performing step zero for the impairment test, the Company is required to make assumptions and judgments including but not limited to the following: the evaluation of macroeconomic conditions as related to the Company's business, industry and market trends, and the overall future financial performance of the Company's reporting units and future opportunities in the markets in which they operate. The Company also considers recent fair value calculations of its indefinite-lived intangible assets and reporting units as well as cost factors such as changes in raw materials, labor or other costs. If the step zero analysis indicates that it is more likely than not that the fair value of a reporting unit or indefinite-lived asset is less than its respective carrying value including goodwill, then the Company would perform an additional quantitative analysis. For goodwill, this involves a two-step process. The first step compares the fair value of the reporting unit, including its goodwill, to its carrying value. If the carrying value of the reporting unit exceeds its fair value, then the second step of the process is performed to determine the amount of impairment. The second step compares the implied fair value of the reporting unit's goodwill to the carrying value of the goodwill. An impairment charge is recognized for the amount the carrying value of the reporting unit's goodwill exceeds its implied fair value. For indefinite-lived intangible assets, the quantitative analysis compares the carrying value of the asset to its fair value and an impairment charge is recognized for the amount its carrying value exceeds its fair value. Determining the fair value of reporting units, indefinite-lived intangible assets and implied fair value of a reporting unit's goodwill is reliant upon estimated future revenues, profitability and cash flows and consideration of market factors. Assumptions, judgments and estimates are complex, subjective and can be affected by a variety of factors, including external factors such as industry and economic trends, and internal factors such as changes in the Company's business strategy or its internal forecasts. Although the Company believes the assumptions, judgments and estimates it has made have been reasonable and appropriate, different assumptions, judgments and estimates could materially affect the Company's results of operations. The Company performed a step zero analysis for its goodwill impairment test in the fourth quarter of fiscal 2015. As a result of this analysis, no further quantitative impairment test was deemed necessary for fiscal 2015. There was no impairment of goodwill as a result of the Company's annual impairment tests completed during the fourth quarters of fiscal years, 2015, 2014 and 2013. In fiscal 2015, as a result of the Business Combination, the Company recorded IPRD of $470.0 million. IPRD was recorded at fair value as of the date of acquisition as an indefinite-lived intangible asset until the completion or abandonment of the associated research and development efforts or impairment. The fair value of the acquired IPRD was determined based on an income approach using the "excess earnings method," which estimated the value of the intangible assets by discounting the future projected earnings of the asset to present value as of the valuation date. Upon completion of development, acquired IPRD assets are transferred to finite-lived intangible assets and amortized over their useful lives. See Note 7 for additional information regarding an impairment of assets recorded in the fourth quarter of fiscal 2014. Intangible Assets with Definite Lives Intangible assets are recorded when such assets are acquired by purchase or license. Finite-lived intangible assets consist primarily of technology licenses, customer relationships, developed technology, a wafer supply agreement, trade names and backlog resulting from business combinations and are subject to amortization. Technology licenses are recorded at cost and are amortized on a straight-line basis over the lesser of the estimated useful life of the technology or the term of the license agreement, ranging from approximately five to eight years. The fair value of customer relationships acquired during fiscal years 2013 and 2015 was determined based on an income approach using the “with and without method," in which the value of the asset is determined by the difference in discounted cash flows of the profitability of the Company "with" the asset and the profitability of the Company "without" the asset. Customer relationships are amortized on a straight-line basis over the estimated useful life, ranging from three to ten years. The fair value of developed technology acquired during fiscal years 2013 and 2015 was determined based on an income approach using the "excess earnings method," which estimated the value of the intangible assets by discounting the future projected earnings of the asset to present value as of the valuation date. Developed technology is amortized on a straight-line basis over the estimated useful life, ranging from four to six years. The fair value of the wafer supply agreement was determined using the incremental income method, which is a discounted cash flow method within the income approach. Under this method, the fair value was estimated by discounting to present value the additional savings from expense reductions in operations at a discount rate to reflect the risk inherent in the wafer supply agreement as well as any tax benefits. The wafer supply agreement is amortized on a units of use activity method and has a useful life of approximately four years. The fair value of trade names acquired in fiscal 2015 was determined based on an income approach using the "relief from royalty method," in which the value of the asset is determined by discounting the future projected cash flows generated from the trade name's estimated royalties. Trade names are amortized on a straight-line basis over the estimated useful life of three years. The fair value of backlog acquired in fiscal 2015 was determined based on an income approach using the "excess earnings method" and is amortized on a straight-line basis over the estimated useful life of one year. The Company regularly reviews identified intangible assets to determine if facts and circumstances indicate that the useful life is shorter than it originally estimated or that the carrying amount of the assets may not be recoverable. If such facts and circumstances exist, the Company assesses the recoverability of identified intangible assets by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. Impairments, if any, are based on the excess of the carrying amount over the fair value of those assets and occur in the period in which the impairment determination was made.
Revenue Recognition	Revenue Recognition The Company's net revenue is generated principally from sales of semiconductor products. The Company recognizes revenue from product sales when the fundamental criteria are met, such as the time at which the title and risk and rewards of product ownership are transferred to the customer, price and terms are fixed or determinable, no significant vendor obligation exists and collection of the resulting receivable is reasonably assured. Sales of products are generally made through either the Company's sales force, manufacturers' representatives or through a distribution network. Revenue from the majority of the Company’s products is recognized upon shipment of the product to the customer from a Company-owned or third-party location. Some revenue is recognized upon receipt of the shipment by the customer. The Company has limited rebate programs offering price protection to certain distributors. These rebates represent less than 1% of net revenue and can be reasonably estimated based on specific criteria included in the rebate agreements and other known factors at the time. The Company reduces revenue and records reserves for product returns and allowances for price protection and stock rotation based on historical experience or specific identification depending on the contractual terms of the arrangement. The Company also recognizes a portion of its net revenue through other agreements such as non-recurring engineering fees, contracts for research and development work, royalty income, intellectual property (IP) revenue, and service revenue. These agreements are collectively less than 1% of consolidated revenue on an annual basis. Revenue from these agreements is recognized when the service is completed or upon certain milestones, as provided for in the agreements. Revenue from certain contracts is recognized on the percentage of completion method based on the costs incurred to date and the total contract amount, plus the contractual fee. If these contracts experience cost overruns, the percentage of completion method is used to determine revenue recognition. Revenue from fixed price contracts is recognized when the required deliverable is satisfied. Royalty income is recognized based on a percentage of sales of the relevant product reported by licensees during the period. The Company additionally licenses or sells its rights to use portions of its IP portfolio, which includes certain patent rights useful in the manufacture and sales of certain products. IP revenue recognition is dependent on the terms of each agreement. The Company will recognize IP revenue (i) upon delivery of the IP and (ii) if the Company has no substantive future obligation to perform under the arrangement. The Company will defer recognition of IP revenue where future performance obligations are required to earn the revenue or the revenue is not guaranteed. Revenue from services is recognized during the period that the service is performed. Accounts receivable are recorded for all revenue items listed above and do not bear interest. The Company evaluates the collectability of accounts receivable based on a combination of factors. In cases where the Company is aware of circumstances that may impair a specific customer’s ability to meet its financial obligations subsequent to the original sale, the Company will record an allowance against amounts due, and thereby reduce the receivable to the amount the Company reasonably believes will be collected. For all other customers, the Company recognizes allowances for doubtful accounts based on the length of time the receivables are past due, industry and geographic concentrations, the current business environment and the Company’s historical experience. The Company's terms and conditions do not give its customers a right of return associated with the original sale of its products. However, the Company will authorize sales returns under certain circumstances, which include perceived quality problems, courtesy returns and like-kind exchanges. The Company evaluates its estimate of returns by analyzing all types of returns and the timing of such returns in relation to the original sale. Reserves are adjusted to reflect changes in the estimated returns versus the original sale of product.
Shipping and Handling Cost	Shipping and Handling Cost The Company recognizes amounts billed to a customer in a sale transaction related to shipping and handling as revenue. The costs incurred by the Company for shipping and handling are classified as cost of goods sold in the Consolidated Statements of Operations.
Research and Development	Research and Development The Company charges all research and development costs to expense as incurred.
Advertising Costs	Advertising Costs The Company expenses advertising costs as incurred. The Company recognized advertising expense of $0.5 million, $0.1 million, and $0.4 million for fiscal years 2015, 2014 and 2013, respectively.
Precious Metals Reclaim	Precious Metals Reclaim The Company uses historical experience to estimate the amount of reclaim on precious metals used in manufacturing at the end of each period and state the reclaim value at the lower of average cost or market. The estimated value to be received from precious metal reclaim is included in "Other current assets" and reclaims submitted for payment are included are included in "Other receivables" on the Consolidated Balance Sheets.
Income Taxes	Income Taxes The Company accounts for income taxes under the liability method, which requires recognition of deferred tax assets and liabilities for the temporary differences between the financial reporting and tax basis of assets and liabilities and for tax carryforwards. Deferred tax assets and liabilities are measured using the enacted statutory tax rates in effect for the years in which the differences are expected to reverse. A valuation allowance is provided against deferred tax assets to the extent the Company determines it is more likely than not (a likelihood of more than 50 percent) that some portion or all of its deferred tax assets will not be realized. A minimum recognition threshold is required to be met before the Company recognizes the benefit of an income tax position in its financial statements. The Company’s policy is to recognize accrued interest and penalties, if incurred, on any unrecognized tax benefits as a component of income tax expense. It is the Company’s policy to invest the earnings of foreign subsidiaries indefinitely outside the U.S. Accordingly, the Company does not record a deferred tax liability for U.S. income taxes on unremitted foreign earnings.
Share-Based Compensation	Stock-Based Compensation Under FASB ASC 718, “Compensation – Stock Compensation," stock-based compensation cost is measured at the grant date based on the estimated fair value of the award using an option pricing model for stock options (Black-Scholes) and market price for restricted stock units, and is recognized as expense over the employee's requisite service period. As of March 28, 2015, total remaining unearned compensation cost related to nonvested restricted stock units and options was $153.0 million, which will be amortized over the weighted-average remaining service period of approximately 1.3 years.
Foreign Currency Translation	Foreign Currency Translation The financial statements of foreign subsidiaries have been translated into U.S. dollars in accordance with FASB ASC 830, “Foreign Currency Matters.” The functional currency for most of the Company’s international operations is the U.S. dollar. The functional currency for the remainder of the Company’s foreign subsidiaries is the local currency. Assets and liabilities denominated in foreign currencies are translated using the exchange rates on the balance sheet dates. Revenues and expenses are translated using the average exchange rates throughout the year. Translation adjustments are shown separately as a component of “Accumulated other comprehensive loss” within “Stockholders’ equity” in the Consolidated Balance Sheets. Foreign currency transaction gains or losses (transactions denominated in a currency other than the functional currency) are reported in “Other (expense) income” in the Consolidated Statements of Operations.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Pronouncements Not Yet Effective In May 2014, the FASB issued Accounting Standards Update ("ASU") 2014-09, "Revenue from Contracts with Customers" that amends existing guidance on revenue recognition. The new guidance is based on principles that an entity will recognize revenue to depict the transfer of goods and services to customers at an amount the entity expects to be entitled to in exchange for those goods and services. The guidance requires additional disclosures regarding the nature, amount, timing, and uncertainty of cash flows and both qualitative and quantitative information about contracts with customers and applied significant judgments. The new authoritative guidance will become effective in the first quarter of fiscal 2018, using one of two retrospective methods of adoption. The Company has not determined which method it will adopt and is currently evaluating the effects the new guidance will have on its consolidated financial statements. Accounting Pronouncements Recently Adopted In July 2013, the FASB issued ASU 2013-11, “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” ASU 2013-11 requires an unrecognized tax benefit, or a portion of an unrecognized tax benefit, to be presented in the financial statements as a reduction of a deferred tax asset or a tax credit carryforward, excluding certain exceptions. This ASU was effective for the Company beginning in the first quarter of fiscal 2015 and the adoption did not have a material impact on the Company's consolidated financial statements.
