The Company and Its Significant

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 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 (the "Business Combination") under a new holding company named Qorvo, Inc. 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 Company is a product and technology leader at the forefront of the growing global demand for always-on broadband connectivity. The Company combines a broad portfolio of radio frequency (“RF”) solutions, highly differentiated semiconductor technologies, deep systems-level expertise and scale manufacturing to supply a diverse group of customers in expanding markets, including smartphones and other mobile devices, defense and aerospace, Wi-Fi customer premises equipment, cellular base stations, optical networks, automotive connectivity, and smart home applications. Within these markets, the Company's products enable a broad range of leading-edge applications - from very-high-power wired and wireless infrastructure solutions to ultra-low-power smart home solutions. The Company's products and technologies help transform how people around the world access their data, transact commerce, and interact with their communities. The Company’s design and manufacturing expertise covers many semiconductor process technologies, which it sources both internally and through external suppliers. The Company’s primary wafer fabrication facilities are located in Florida, North Carolina, Oregon and Texas and its primary assembly and test facilities are located in China, Costa Rica, Germany and Texas. The Company operates design, sales and manufacturing facilities throughout Asia, Europe and North America. Principles of Consolidation and Basis of Presentation 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. Certain items in the fiscal years 2017 and 2016 financial statements have been reclassified to conform to the fiscal 2018 presentation, such as restricted cash in accordance with Accounting Standards Update ("ASU") 2016-18. 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 31, 2018 , April 1, 2017 , and April 2, 2016 . Fiscal years 2018 and 2017 were 52-week years, and fiscal year 2016 was a 53-week year. 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. During the first quarter of fiscal 2018, the Company changed its accounting estimate for the expected useful lives of certain machinery and equipment. The Company evaluated its asset base and reassessed the estimated useful lives of certain machinery and equipment in connection with its implementation of several capital projects, including the migration of certain surface acoustic wave ("SAW") processes from 4-inch to 6-inch toolsets and certain bulk acoustic wave ("BAW") processes from 6-inch to 8-inch toolsets. Based on its ability to re-use equipment across generations of process technologies and historical usage trends, the Company determined that the expected useful lives for certain machinery and equipment should be increased by up to three years to reflect more closely the estimated economic lives of those assets. This change in estimate was applied prospectively effective for the first quarter of fiscal 2018 and resulted in a decrease in depreciation expense of $59.7 million for fiscal 2018. This decrease in depreciation expense for fiscal 2018 resulted in the following: (1) an increase in income from operations of $47.4 million ; (2) an increase in net income of $44.1 million ; (3) an improvement in earnings per share of $0.34 ; and (4) a reduction in inventory of $12.3 million . 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 31, 2018 and April 1, 2017 consisted of auction rate securities ("ARS"). 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 cost of available-for-sale securities is adjusted for premiums and discounts, with the amortization or accretion of such amounts 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 net realizable value (cost is based on standard cost, which approximates actual average cost). 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 and 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 was not significant during the periods presented. Other Receivables The Company records miscellaneous non-product receivables that are collectible within 12 months in “Other receivables,” such as value-added tax receivables ( $38.1 million as of March 31, 2018 and $55.4 million as of April 1, 2017 , which are reported on a net basis), precious metal reclaims submitted for payment and other miscellaneous items. 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 thirty-nine years . The Company capitalizes interest on borrowings related to eligible capital expenditures. Capitalized interest is added to the cost of qualified assets and depreciated together with that asset cost. 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 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. The Company periodically evaluates the period over which it expects to recover the economic value of the Company’s property and equipment, considering factors such as changes in machinery and equipment technology, the ability to re-use equipment across generations of process technology and historical usage trends. If the Company determines that the useful lives of its assets are shorter or longer than originally estimated, the rate of depreciation is adjusted to reflect the revised useful lives of the assets. The Company assesses property and equipment for impairment when events or changes in circumstances indicate that the carrying amount of its assets may not be recoverable. Factors that are considered in deciding when to perform an impairment review include an adverse change in the use of the Company’s assets or an expectation that the assets will be sold or otherwise disposed. 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. Assets identified as “held for sale” are recorded at the lesser of their carrying value or their fair market value less costs to sell. Impairment, if any, is based on the excess of the carrying amount over the fair value of those 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. The Company accounts for goodwill and indefinite-lived intangible assets in accordance with the Financial Accounting Standards Board ("FASB") guidance, which requires annual testing for impairment or whenever events or circumstances make it more likely than not that an impairment may have occurred. The Company performs its annual impairment tests on the first day of the fourth quarter in each fiscal year. Indefinite-lived intangible assets consist 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 its impairment test, the Company is required to make assumptions and judgments, including 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 its results of operations. Goodwill Goodwill is allocated to the Company's reporting units based on the expected benefit from the synergies of the business combinations generating the underlying goodwill. As of March 31, 2018 , the Company's goodwill balance of $2,173.9 million is allocated between its Mobile Products ("MP") and Infrastructure and Defense Products ("IDP") reporting units. In fiscal years 2018 and 2017, the Company completed qualitative assessments of the fair value of its reporting units and concluded that goodwill was not impaired. For fiscal 2016, although there were no indicators of impairment, the Company opted to bypass the qualitative assessment and proceeded to perform fair value assessments of its reporting units (the first step of the quantitative impairment analysis) as the fair value of the reporting units had changed (due to the Business Combination) since the last time the Company performed a quantitative analysis. The quantitative assessments performed reaffirmed that there were no indicators of impairment for fiscal 2016. In performing these quantitative assessments, consistent with its historical approach, the Company used both the income and market approaches to estimate the fair value of its reporting units. The income approach involves discounting future estimated cash flows. The sum of the reporting unit cash flow projections was compared to the Company's market capitalization in a discounted cash flow framework to calculate an overall implied internal rate of return (or discount rate) for the Company. The Company's market capitalization was adjusted to a control basis assuming a reasonable control premium, which resulted in an implied discount rate. This implied discount rate serves as a baseline for estimating the specific discount rate for each reporting unit. The discount rate used is the value-weighted average of the Company's estimated cost of equity and debt (“cost of capital”) derived using both known and estimated customary market metrics. The Company's weighted average cost of capital is adjusted for each reporting unit to reflect a risk factor, if necessary, for each reporting unit. The Company performs sensitivity tests with respect to growth rates and discount rates used in the income approach. The Company believes the income approach is appropriate because it provides a fair value estimate based upon the respective reporting unit’s expected long-term operations and cash flow performance. The Company considered historical rates and current market conditions when determining the discount and growth rates used in its analysis. For fiscal 2016, the material assumptions used for the income approach were eight years of projected net cash flows and a long-term growth rate of 3% for both the MP and IDP reporting units. A discount rate of 15% and 16% was used for the MP and IDP reporting units, respectively. In applying the market approach, valuation multiples are derived from historical and projected operating data of selected guideline companies, which are evaluated and adjusted, if necessary, based on the strengths and weaknesses of the reporting unit relative to the selected guideline companies. The valuation multiples are then applied to the appropriate historical and/or projected operating data of the reporting unit to arrive at an indication of fair value. The Company believes the market approach is appropriate because it provides a fair value using multiples from companies with operations and economic characteristics similar to its reporting units. The Company weighted the results of the income approach and the results of the market approach at 50% each and for the MP and IDP reporting units, concluded that the fair value of the reporting units was determined to be substantially in excess of the carrying value, and as such, no further analysis was warranted. Under the income approach described above, the following indicates the sensitivity of key assumptions utilized in the assessment. A one percentage point decrease in the discount rate would have increased the fair value of the MP and IDP reporting units by approximately $660.0 million and $140.0 million , respectively, while a one percentage point increase in the discount rate would have decreased the fair value of the MP and IDP reporting units by approximately $560.0 million and $110.0 million , respectively. A one percentage point decrease in the long-term growth rate would have decreased the fair value of the MP and IDP reporting units by approximately $290.0 million and $50.0 million , respectively, while a one percentage point increase in the long-term growth rate would have increased the fair value of the MP and IDP reporting units by approximately $340.0 million and $70.0 million , respectively. Intangible Assets with Indefinite Lives 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 ("R&D") 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. During fiscal years 2018 , 2017 and 2016 , the Company completed and transferred into developed technology approximately $37.0 million , $220.0 million and $203.0 million , respectively, of IPRD. The Company performed a qualitative assessment of the remaining IPRD of $10.0 million during fiscal 2018 and concluded that IPRD was not impaired. 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 and trade names 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, 2015 and 2017 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, 2015 and 2017 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 three to six years. The fair value of trade names acquired in fiscal years 2015 and 2017 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 two to three years. The Company regularly reviews identified intangible assets to determine if facts and circumstances indicate that the useful lives have changed from the original estimate 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. Accrued Liabilities The "Accrued liabilities" balance as of March 31, 2018 and April 1, 2017 includes accrued compensation and benefits of $96.7 million and $98.7 million , respectively, and interest payable of $23.1 million and $23.2 million , respectively. 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 5% 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, stock rotation, and scrap allowance 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 R&D work, royalty income, intellectual property ("IP") revenue, and service revenue. These agreements are collectively less than 1% of consolidated annual revenue. 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 upon delivery of the IP 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 R&D costs to expense as incurred. 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 states 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 in "Other receivables" in 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 for each tax jurisdiction 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 that some portion or all of its deferred tax assets will not be realized. A more likely than not 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 current intent and policy to invest the earnings of foreign subsidiaries indefinitely outside the U.S., except for Qorvo International Pte. Ltd. in Singapore. Accordingly, the Company does not record a deferred tax liability for U.S. income taxes on unremitted foreign earnings of other foreign subsidiaries. Stock-Based Compensation Under FASB Accounting Standards Codification ("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 31, 2018 , total remaining unearned compensation cost related to unvested restricted stock units and options was $72.8 million , which will be amortized over the weighted-average remaining service period of approximately 1.2 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 income (expense)” in the Consolidated Statements of Operations. Recent Accounting Pronouncements Accounting Pronouncements Not Yet Effective In January 2017, the FASB issued ASU 2017-04, "Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." The new guidance simplifies the subsequent measurement of goodwill by eliminating the second step from the quantitative goodwill impairment test. The Company will continue to have the option to perform a qualitative assessment to determine if a quantitative goodwil

CONCENTRATIONS OF CREDIT RISK	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 revenue for the respective periods, are summarized as follows: Fiscal Year 2018 2017 2016 Apple Inc. ("Apple") 36% 34% 37% Huawei Technologies Co., Ltd. 8% 11% 12% The Company provided its products to Apple through sales to multiple contract manufacturers. These customers primarily purchase cellular RF and Wi-Fi solutions offered by the Company's MP segment for a variety of mobile devices, including smartphones, notebook computers, wearables, tablets and cellular-based applications for the Internet of Things ("IoT"). Accounts receivable related to these customers (which includes multiple contract manufacturers) accounted for 26% , 40% , and 40% of the Company's total net accounts receivable balance as of March 31, 2018 , April 1, 2017 and April 2, 2016 , respectively.

The Company's Level 2 ARS are valued based on quoted prices for identical or similar instruments in markets that are not active. (2) 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 31, 2018 and April 1, 2017 , 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 11 for further information on impairment of property and equipment. 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. See Note 8 for the fair value of the Company's long-term debt.

BUSINESS ACQUISITION DISCLOSURE [Abstract]
BUSINESS ACQUISITIONS	BUSINESS ACQUISITIONS Acquisition of GreenPeak Technologies, B.V. During fiscal 2017, the Company completed the acquisition of GreenPeak Technologies, B.V. ("GreenPeak"), a leader in ultra-low power, short RF communication technology. The acquisition expanded the Company's offerings to include integrated RF solutions and systems-on-a-chip ("SoCs") for the connected home. The Company acquired 100% of the outstanding equity securities of GreenPeak for a purchase price of $118.1 million , net of cash acquired of $0.7 million . The total purchase price was allocated to GreenPeak's assets and liabilities based upon fair values as determined by the Company and resulted in goodwill of $38.2 million . The measurement period (up to one year from the acquisition date pursuant to ASC Topic 805 "Business Combinations" ) related to the acquisition of GreenPeak was concluded during the first quarter of fiscal 2018. The GreenPeak acquisition resulted in an increase in intangible assets of $82.1 million . The more significant intangible assets acquired were developed technology of $74.2 million (which is being amortized over 7 years) and customer relationships of $5.6 million (which is being amortized over 3 years). Business Combination between RFMD and 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. Based on an evaluation of the provisions of FASB ASC Topic 805, “ Business Combinations ,” RFMD was determined to be the acquirer for accounting purposes. The initial allocation to goodwill of $2,036.7 million represented the excess of the purchase price over the fair value of assets acquired and liabilities assumed, which amount was allocated to the Company's MP operating segment ( $1,745.5 million ) and IDP operating segment ( $291.2 million ). During the measurement period (which was concluded during the third quarter of fiscal 2016), adjustments of $3.8 million and $1.1 million were made to reduce goodwill and increase property and equipment and deferred taxes, respectively. Goodwill recognized from the Business Combination is not deductible for income tax purposes. The Business Combination resulted in an increase in intangible assets of $2,394.0 million . The more significant intangible assets acquired were developed technology of $610.0 million and customer relationships of $1,220.0 million (which are both being amortized over periods between 4 and 6 years) and IPRD of $470.0 million , of which $460.0 million has been completed as of March 31, 2018 and transferred to finite-lived intangible assets (which are being amortized over periods between 4 and 6 years ). During fiscal years 2018 , 2017 and 2016 , the Company incurred integration costs of approximately $6.2 million , $16.9 million , and $26.5 million , respectively, associated with the Business Combination. During fiscal years 2018 , 2017 and 2016 , the Company incurred restructuring costs of approximately $2.6 million , $2.0 million , and $10.1 million , respectively, associated with the Business Combination. The acquisition, integration and restructuring costs are being expensed as incurred and are presented in the Consolidated Statements of Operations as "Other operating expense." See Note 11 for further information on the restructuring.

DEBT	DEBT Debt as of March 31, 2018 and April 1, 2017 is as follows (in thousands): March 31, 2018 April 1, 2017 6.75% Senior Notes due 2023 $ 444,464 $ 450,000 7.00% Senior Notes due 2025 548,500 550,000 Less unamortized issuance costs (9,674 ) (10,846 ) Total long-term debt $ 983,290 $ 989,154 Credit Agreement On December 5, 2017 (the "Closing Date"), the Company and certain of its material domestic subsidiaries (the "Guarantors") entered into a five-year unsecured senior credit facility pursuant to a credit agreement 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 senior delayed draw term loan of up to $400.0 million (the "Term Loan") and a $300.0 million senior revolving line of credit (the "Revolving Facility", together with the Term Loan, the "Credit Facility"). On the Closing Date, $100.0 million of the Term Loan was funded (and was subsequently repaid in March 2018), with the remainder available, at the discretion of the Company, in up to two draws prior to June 5, 2018 . The Revolving Facility includes a $25.0 million sublimit for the issuance of standby letters of credit and a $10.0 million sublimit for swing line loans. The Company may request, at its option and at any time, that the Credit Facility be increased by an amount not to exceed $300.0 million , subject to securing additional funding commitments from the existing or new lenders. The Credit Facility is available to finance working capital, capital expenditures and other corporate purposes. The Company’s obligations under the Credit Agreement are jointly and severally guaranteed by the Guarantors. Upon execution of the Credit Agreement, the Company terminated its prior credit agreement, dated as of April 7, 2015 , as amended, with Bank of America, N.A., thus terminating and releasing the Company’s obligations and guarantees of certain of its subsidiaries under that agreement. During fiscal 2018 , there were no borrowings under the Revolving Facility. The Company had no outstanding amounts under the Credit Facility as of March 31, 2018 . At the Company’s option, loans under the Credit Agreement 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 Base 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 reserve adjusted London Interbank Offered Rate (or a comparable or successor rate), for dollar deposits for interest periods of one, two, three, six or twelve months, as selected by the Company. The Applicable Rate for Eurodollar Rate loans ranges from 1.125% per annum to 1.375% per annum. The Applicable Rate for Base Rate loans ranges from 0.125% per annum to 0.375% per annum. Interest for Eurodollar Rate loans will 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 will 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. Interest paid on the Term Loan during fiscal 2018 was $0.7 million . The Credit Agreement contains various conditions, covenants and representations with which the Company must comply in order to borrow funds and to avoid an event of default, including the following financial covenants that the Company must maintain: (i) a consolidated leverage ratio not to exceed 3.0 to 1.0 as of the end of any fiscal quarter of the Company, provided that in connection with a permitted acquisition in excess of $300.0 million , the Company's maximum consolidated leverage ratio may increase on two occasions during the term of the Credit Facility to 3.5 to 1.0 for four consecutive fiscal quarters, beginning with the fiscal quarter in which such acquisition occurs and (ii) an interest coverage ratio not to be less than 3.0 to 1.0 as of the end of any fiscal quarter of the Company. As of March 31, 2018 , the Company was in compliance with these covenants. The Credit Agreement also contains customary events of default. The occurrence of an event of default can result in the exercise of remedies including an increase in the applicable rate of interest by 2.00% , termination of undrawn commitments under the Credit Facility, declaration that all outstanding loans are due and payable and requiring cash collateral deposits in respect of outstanding letters of credit. Outstanding amounts are due in full on the maturity date of December 5, 2022 (with amounts borrowed under the swingline option due in full no later than ten business days after such loan is made), subject to scheduled amortization of the Term Loan principal as set forth in the Credit Agreement prior to the maturity date. Senior Notes On November 19, 2015, the Company completed an offering of $450.0 million aggregate principal amount of its 6.75% senior notes due December 1, 2023 (the “2023 Notes”) and $550.0 million aggregate principal amount of its 7.00% senior notes due December 1, 2025 (the “2025 Notes” and, together with the 2023 Notes, the “Notes”). The Notes were sold in the U.S. to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and outside the U.S. pursuant to Regulation S under the Securities Act. The Notes were issued pursuant to an indenture dated as of November 19, 2015 (the "Indenture") containing customary events of default, including payment default, failure to provide certain notices and certain provisions related to bankruptcy events. The Indenture also contains customary negative covenants. On September 19, 2016, the Company completed an exchange offer, in which all of the 2023 Notes and substantially all of the 2025 Notes were exchanged for new notes that have been registered under the Securities Act. At any time prior to December 1, 2018, the Company may redeem all or part of the 2023 Notes, at a redemption price equal to their principal amount, plus a “make whole” premium as of the redemption date, and accrued and unpaid interest. In addition, at any time prior to December 1, 2018, the Company may redeem up to 35% of the original aggregate principal amount of the 2023 Notes with the proceeds of one or more equity offerings, at a redemption price equal to 106.75% , plus accrued and unpaid interest. Furthermore, at any time on or after December 1, 2018, the Company may redeem the 2023 Notes, in whole or in part, at once or over time, at the specified redemption prices set forth in the Indenture plus accrued and unpaid interest thereon to the redemption date (subject to the rights of holders of record on the relevant record date to receive interest due on the relevant interest payment date). In March 2018, the Company repurchased $5.5 million of the 2023 Notes at a redemption price of 107.50% plus accrued and unpaid interest. At any time prior to December 1, 2020, the Company may redeem all or part of the 2025 Notes, at a redemption price equal to their principal amount, plus a “make whole” premium as of the redemption date, and accrued and unpaid interest. In addition, at any time prior to December 1, 2018, the Company may redeem up to 35% of the original aggregate principal amount of the 2025 Notes with the proceeds of one or more equity offerings, at a redemption price equal to 107.00% , plus accrued and unpaid interest. Furthermore, at any time on or after December 1, 2020, the Company may redeem the 2025 Notes, in whole or in part, at once or over time, at the specified redemption prices set forth in the Indenture plus accrued and unpaid interest thereon to the redemption date (subject to the rights of holders of record on the relevant record date to receive interest due on the relevant interest payment date). In March 2018, the Company repurchased $1.5 million of the 2025 Notes at a redemption price of 109.50% plus accrued and unpaid interest. Interest is payable on June 1 and December 1 of each year on the 2023 Notes at a rate of 6.75% per annum and on the 2025 Notes at a rate of 7.00% per annum. Interest paid on the Notes during fiscal 2018 and fiscal 2017 was $68.9 million and $71.2 million , respectively. The 2023 Notes and the 2025 Notes are traded over the counter, and their fair values as of March 31, 2018 of $474.5 million and $596.5 million , respectively (compared to carrying values of $444.5 million and $548.5 million , respectively) were estimated based upon the values of their last trade at the end of the period. The fair values of the 2023 Notes and the 2025 Notes were $489.4 million and $607.8 million , respectively (compared to carrying values of $450.0 million and $550.0 million , respectively), as of April 1, 2017 . Interest Expense During fiscal 2018 , the Company recognized $70.5 million of interest expense related to the Notes and the Term Loan, which was offset by $13.6 million of interest capitalized to property and equipment. During fiscal 2017 and fiscal 2016 , the Company recognized $69.9 million and $25.8 million , respectively, of interest expense related to the Notes, which was partially offset by $13.6 million and $5.2 million , respectively, of interest capitalized to property and equipment.

RETIREMENT BENEFIT PLANS	RETIREMENT BENEFIT PLANS Defined Contribution Plans The Company offers tax-beneficial retirement contribution plans to eligible employees in the U.S. and certain other countries. Eligible employees in certain countries outside of the U.S. are eligible to participate in stakeholder or national pension plans with differing eligibility and contributory requirements based on local and national regulations. U.S. employees are eligible to participate in the Company's fully qualified 401(k) plan 30 days after their date of hire. An employee may invest pretax earnings in the 401(k) plan up to the maximum legal limits (as defined by Federal regulations). Employer contributions to the 401(k) plan are made at the discretion of the Company’s Board of Directors. Employees are immediately vested in their own contributions as well as employer matching contributions. In total, the Company contributed $14.0 million , $11.5 million and $11.7 million to its domestic and foreign defined contribution plans during fiscal years 2018 , 2017 and 2016 , respectively. Defined Benefit Pension Plans 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 $4.0 million and $3.3 million of assets valued as of March 31, 2018 and April 1, 2017 , respectively. Assets of the funded plan are included in "Other non-current assets" in the Consolidated Balance Sheets.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENT LIABILITIES	COMMITMENTS AND CONTINGENT LIABILITIES The Company leases certain of its corporate, wafer fabrication and other facilities from multiple third-party real estate developers. The operating leases expire at various dates through 2034 , and some of these leases have renewal options, with the longest ranging up to two , ten -year periods. Several of these leases also include market rate rent escalations, rent holidays, and leasehold improvement incentives, all of 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 four years. As of March 31, 2018 , the total future minimum lease payments related to facility and equipment operating leases was approximately $68.6 million . In the fourth quarter of fiscal 2018, the Company entered into a capital lease for a facility in Beijing, China that will allow the Company to consolidate several leased facilities as well as provide additional manufacturing space. The lease term is expected to commence in fiscal 2020 and therefore is not recorded on the Consolidated Balance Sheet as of March 31, 2018 . The initial term of the lease is five years. The lease includes multiple renewal options, and the maximum lease term cannot exceed 30 years. Minimum future lease payments under non-cancelable operating and capital leases as of March 31, 2018 , are as follows (in thousands): Fiscal Year Operating Leases Capital Lease Total 2019 $ 12,490 $ 0 $ 12,490 2020 11,429 1,047 12,476 2021 10,469 1,047 11,516 2022 8,577 1,047 9,624 2023 7,163 1,047 8,210 Thereafter 18,454 48,243 66,697 Total minimum lease payments $ 68,582 $ 52,431 $ 121,013 Rent expense under operating leases, covering facilities and equipment, was approximately $16.3 million , $14.8 million , and $14.2 million for fiscal years 2018 , 2017 and 2016 , 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 and Related Activities [Abstract]
RESTRUCTURING	RESTRUCTURING During fiscal 2018, the Company recorded approximately $67.7 million of restructuring expenses in "Other operating expense" in the Consolidated Statements of Operations, related to actions initiated in fiscal 2018 to improve operating efficiencies and actions initiated in fiscal 2015 as a result of the Business Combination. During fiscal 2018, the Company initiated restructuring actions to improve operating efficiencies, and, as a result of these actions, recorded approximately $18.3 million of employee termination benefits. As a result of this restructuring plan, in the fourth quarter of fiscal 2018, the Company also adjusted the carrying value of certain of its held for sale assets located in China and the U.S. to fair market value (resulting in impairment charges totaling approximately $46.3 million , pursuant to ASC 360). The fair value of the assets is based on quotes from third parties. The Company expects to record approximately $0.9 million of additional restructuring charges in fiscal 2019 primarily associated with employee termination benefits. During fiscal years 2018 , 2017 and 2016 , the Company recorded restructuring expenses (including employee termination benefits, stock-based compensation and ongoing expenses related to exited leased facilities) of approximately $2.7 million , $2.1 million and $10.2 million , respectively, primarily as a result of the Business Combination.

Income Taxes

Income Taxes	12 Months Ended
	Mar. 31, 2018
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES On December 22, 2017, the Tax Act was signed into law in the U.S. The Tax Act significantly revises the future ongoing U.S. corporate income tax by, among other things, lowering U.S. corporate income tax rates, providing full expensing for investments in new and used qualified property made after September 27, 2017, and implementing a territorial tax system. Due to the timing of the Company's fiscal year, the lower corporate income tax rate will be phased in, resulting in a U.S. statutory federal rate of approximately 31.5% for our fiscal year ended March 31, 2018, and 21% for subsequent fiscal years. The Tax Act implements a territorial tax system that eliminates U.S. federal income taxes on dividends from 10% owned foreign subsidiaries, but limits the ability to credit certain foreign taxes that existed prior to enactment of the Tax Act. In connection with the transition to the new territorial tax system, a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries is being imposed (the “Transitional Repatriation Tax”), which is payable over eight years. In addition, the Tax Act includes two new U.S. tax base erosion provisions, the Global Intangible Low-Taxed Income ("GILTI") provisions and the Base-Erosion and Anti-Abuse Tax (“BEAT”) provisions, which become effective for the Company in fiscal 2019. The SEC issued Staff Accounting Bulletin No. 118 (“SAB 118”) to address the appropriate accounting treatment when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Act. SAB 118 allows for a measurement period of up to one year after the enactment date of the Tax Act to finalize the recording of the related tax impacts. In the interim periods, provisional amounts are to be recorded where the income tax effect can be reasonably estimated. The Company’s accounting for the Tax Act is incomplete, but the Company has recorded the provisional estimates discussed below and will finalize and record any resulting adjustments within the one-year measurement period. The final transitional impacts of the Tax Act may differ from the below provisional estimates, possibly materially, due to, among other things: legislation by states with respect to the Tax Act; evolving technical interpretations of the Tax Act; legislative action to address questions that arise because of the Tax Act; clarification of the application of accounting standards for income taxes or related interpretations in response to the Tax Act; or updates or changes to provisional amounts the Company has utilized to calculate the transitional impacts, including impacts from changes to current year earnings and tax liabilities, deferred tax assets and liabilities, earnings and profits at foreign subsidiaries, tax pools at foreign subsidiaries, foreign tax credits and foreign exchange rates. The impact of the Tax Act resulted in a provisional tax expense of $77.3 million in fiscal 2018 . This was comprised of a provisional Transitional Repatriation Tax expense of $116.4 million , offset by a provisional deferred tax benefit of $39.1 million from the remeasurement of U.S. deferred tax assets and liabilities. Both the tax charge and the tax benefit represent provisional amounts and the Company’s current best estimates. The Transitional Repatriation Tax is a one-time tax on accumulated and current earnings and profits (“E&P”) of foreign companies with U.S. owners that have not previously been subjected to tax in the U.S. A portion of the E&P is subject to a tax rate of 15.5% and the remainder to 8% . To determine the amount of the Transitional Repatriation Tax, the Company must determine for each foreign company in which it has a direct or indirect ownership interest, among other factors, the amount of post-1986 E&P of its foreign subsidiaries, as well as the amount of non-U.S. income taxes paid on such earnings. The Company was able to make a reasonable estimate of the Transitional Repatriation Tax on its wholly owned foreign subsidiaries and has recorded a provisional Transitional Repatriation Tax expense of $116.4 million as a component of its current income tax provision. No reasonable estimate has been made with respect to direct and indirect investments in other foreign companies. The Company is continuing to gather and analyze additional information and guidance to complete the accounting with respect to its calculation of E&P, non-U.S. income taxes paid, and the portion taxable at the 15.5% tax rate. The Tax Act allows the tax liability arising from the Transitional Repatriation Tax to be paid on an installment basis over eight years, resulting in a provisional increase in the long-term tax liability account included in "Other long-term liabilities" in the Company's Consolidated Balance Sheets. The deferred tax assets and liabilities of the Company are impacted by the Tax Act. The reduction in the U.S. federal corporate tax rate from 35% to 21% for tax years beginning after December 31, 2017, requires the Company to remeasure its deferred tax assets and liabilities. The Company has evaluated this change and recorded a decrease to net deferred tax liabilities with a corresponding increase to deferred tax benefit of $39.1 million . In addition, the full expensing of investments in qualified property after September 27, 2017, impacts the calculation of deferred tax balances. The provisional amount for full expensing requires further analysis to determine which fixed assets placed in service after September 27, 2017, meet the qualification requirements. The Company is still in the process of evaluating the state tax impact on deferred tax balances, including valuation allowances, from the full expensing provision and other provisions of the Tax Act. GILTI creates a new requirement that certain income earned by foreign subsidiaries must be currently included in the gross income of the U.S. stockholder. Due to the complexity of the new GILTI tax rules, the Company continues to evaluate this provision of the Tax Act and the application of ASC 740, " Income Taxes." Under U.S. GAAP, the Company is allowed to make an accounting policy choice of either: (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the “period cost method”) or (2) factoring such amounts into the Company's measurement of its deferred taxes (the “deferred method”). The Company has not yet completed its analysis of the GILTI tax rules and is not yet able to reasonably estimate the effect of this provision or make the accounting policy election. As a result, the Company has not made any provisional adjustments related to potential GILTI tax in its financial statements and has not made a policy decision regarding whether to record deferred taxes for GILTI. Beginning in calendar year 2018 , the Tax Act provides a 100% deduction for dividends received from 10-percent owned foreign corporations by U.S. corporate stockholders, subject to a one-year holding period. Although dividend income is now exempt from U.S. federal tax in the hands of the U.S. corporate stockholders, companies must still apply the guidance of ASC 740-30-25-18 to account for the tax consequences of outside basis differences and other tax impacts of their investments in non-U.S. subsidiaries. While the Company has accrued the Transitional Repatriation Tax on the deemed repatriated earnings that were previously indefinitely reinvested, it currently intends to only repatriate amounts where no additional withholding taxes will be imposed on a distribution. The Company has determined that Singapore does not impose a withholding tax on dividends and no longer takes the position that earnings are permanently reinvested for our operating subsidiary in Singapore. With respect to its other foreign subsidiaries, the Company continues to account for them as permanently reinvested while it continues to evaluate the impacts of the Tax Act on its operations in accordance with guidance issued under SAB 118.

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): Fiscal Year 2018 2017 Deferred income tax assets: Inventory reserve $ 9,894 $ 15,599 Equity compensation 37,724 83,333 Net operating loss carry-forwards 50,128 40,575 Research and other credits 39,513 92,793 Employee benefits 12,842 13,247 Other deferred assets 16,620 23,355 Total deferred income tax assets 166,721 268,902 Valuation allowance (42,787 ) (33,104 ) Total deferred income tax assets, net of valuation allowance $ 123,934 $ 235,798 Deferred income tax liabilities: Amortization and purchase accounting basis difference $ (101,261 ) $ (258,422 ) Accumulated depreciation/basis difference (63,363 ) (91,337 ) Total deferred income tax liabilities (164,624 ) (349,759 ) Net deferred income tax liabilities $ (40,690 ) $ (113,961 ) Amounts included in the Consolidated Balance Sheets: Non-current assets 22,394 17,550 Non-current liabilities (63,084 ) (131,511 ) Net deferred income tax liabilities $ (40,690 ) $ (113,961 ) The Company has recorded a $42.8 million and a $33.1 million valuation allowance against the U.S. deferred tax assets and deferred tax assets at foreign subsidiaries as of March 31, 2018 , and April 1, 2017 , respectively. These valuation allowances were established based upon management's opinion that it is more likely than not (a likelihood of more than 50 percent) 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. Management reevaluates the ability to realize the benefit of the deferred tax assets of the Company on a quarterly basis. The valuation allowance against deferred tax assets increased by $9.7 million in fiscal 2018 . The increase was comprised of a $6.8 million increase resulting from tax rate changes, primarily the federal rate changes enacted in the Tax Act, a $1.9 million increase in the state deferred tax for net operating losses and tax credits, a $1.0 million increase for deferred tax assets for net operating losses at other foreign subsidiaries and a $0.5 million increase in the valuation allowance for state tax credits due to the adoption of ASU 2016-09. It was partially offset by a $0.5 million decrease in valuation allowance for federal deferred tax assets for foreign tax credits. At the end of fiscal 2018 , a $2.0 million valuation allowance remained against deferred tax assets at other foreign subsidiaries and a $40.8 million valuation allowance remained against domestic deferred tax assets as management has determined it is more likely than not that the related deferred tax assets will not be realized. The valuation allowance against deferred tax assets decreased by $1.6 million in fiscal 2017 . The decrease was comprised of a $5.2 million decrease in the valuation allowance for foreign deferred tax assets primarily resulting from the removal of the valuation allowance at a China manufacturing subsidiary as management has determined it is more likely than not that the related deferred tax assets will be realized. The decrease was offset by a $2.8 million increase in the valuation allowance for federal deferred tax assets for foreign tax credits and state deferred tax assets for net operating losses and tax credits, as well as a $0.8 million increase for deferred tax assets for net operating losses at other foreign subsidiaries. At the end of fiscal 2017 , a $0.8 million valuation allowance remained against deferred tax assets at other foreign subsidiaries and a $32.3 million valuation allowance remained against domestic deferred tax assets as management determined it was more likely than not that the related deferred tax assets would not be realized. During fiscal 2017 , the Company's China manufacturing subsidiary, which operates as a cost plus manufacturer for another Qorvo subsidiary, exited its start-up operational phase and generated sufficient income to substantially offset the losses earned in prior years. The balance of the cumulative pre-tax book loss was expected to be offset by income in the first half of fiscal 2018 as production at the assembly and test facility continued to increase as the Company reduced its dependence on outside assembly and test subcontractors. After evaluating the positive and negative evidence, management determined that it was more likely than not that the deferred tax assets of this China manufacturing subsidiary would be realized and a valuation allowance would not be provided as of the end of fiscal 2017 . The valuation allowance against deferred tax assets increased by $20.9 million in fiscal 2016 . The increase was comprised of a $20.2 million increase in the valuation allowance for state deferred tax assets for net operating losses and tax credits, a $5.0 million increase in the valuation allowance for foreign net operating loss deferred tax assets, and a $4.3 million decrease in the valuation allowance related to a deferred tax asset recorded in the initial purchase price accounting for the Business Combination. The Business Combination adjustment related to a deferred tax asset which was recorded during fiscal 2015 in the initial purchase price accounting with a full valuation allowance, but which deferred tax asset was determined in fiscal 2016 to not exist as of the acquisition date. Accordingly, in fiscal 2016 , that deferred tax asset was removed along with the offsetting deferred tax asset valuation allowance. At the end of fiscal 2016 , a $5.2 million valuation allowance remained against foreign deferred tax assets and a $29.5 million valuation allowance remained against domestic deferred tax assets as management determined it was more likely than not that the related deferred tax assets would not be realized, effectively increasing the domestic net deferred tax liabilities. During fiscal 2016 , North Carolina enacted legislation to reduce the corporate income tax rate from 5% to 4% and phase-in over a three-year period a move to a single sales factor apportionment methodology. In addition, the Company underwent operational changes to leverage existing resources and capabilities of its Singapore subsidiary and consolidate operations and responsibilities associated with its foreign back-end manufacturing operations and foreign customers in that Singapore subsidiary. Together these changes resulted in a significant decrease in the amount of future taxable income expected to be allocated to North Carolina and other states in which the net operating loss and tax credit carryovers existed. As a result, it was no longer more likely than not that the deferred tax assets related to those state net operating loss and tax credit carryovers for which a valuation allowance was being provided will be used before they expire. The deferred tax asset for foreign net operating losses primarily related to the China subsidiary which owns the internal assembly and test facility that became operational during fiscal 2016 and had incurred losses since inception. As of March 31, 2018 , the Company had federal loss carryovers of approximately $305.0 million that expire in fiscal years 2020 to 2038 if unused and state losses of approximately $147.3 million that expire in fiscal years 2019 to 2038 if unused. Federal research credits of $54.9 million , and state credits of $58.7 million may expire in fiscal years 2019 to 2038 and 2019 to 2033 , respectively. Foreign losses in the Netherlands of approximately $7.8 million expire in fiscal years 2019 to 2027 . 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 Section 382 of the Internal Revenue Code of 1986, as amended (the "Code") 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, except for the earnings of Qorvo International Pte. Ltd., our operating subsidiary in Singapore. No provision for U.S. federal, state income taxes and foreign local withholding taxes has been made with respect to any of the other foreign subsidiaries. It is not practical to estimate the additional tax that would be incurred, if any, if the permanently reinvested earnings were repatriated. The Company has 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. In February 2017, Singapore enacted legislation that will exclude from the Company's existing Development and Expansion Incentive grant the benefit of the reduced tax rate for intellectual property income earned after June 30, 2021. Incentives from these countries are subject to the Company meeting certain employment and investment requirements. Income tax expense decreased by $7.9 million (approximately $0.06 per basic and diluted share impact) in fiscal 2018 and $2.7 million (approximately $0.02 per basic and diluted share impact) in fiscal 2017 as a result of these agreements. The Company’s gross unrecognized tax benefits totaled $122.8 million as of March 31, 2018 , $90.6 million as of April 1, 2017 , and $69.1 million as of April 2, 2016 . Of these amounts, $118.7 million (net of federal benefit of state taxes), $84.4 million (net of federal benefit of state taxes) and $64.2 million (net of federal benefit of state taxes) as of March 31, 2018 , April 1, 2017 , and April 2, 2016 , 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 fiscal 2016 through fiscal 2018 beginning and ending amount of gross unrecognized tax benefits is as follows (in thousands): Fiscal Year 2018 2017 2016 Beginning balance $ 90,615 $ 69,052 $ 59,397 Additions based on positions related to current year 26,431 20,036 9,374 Additions for tax positions in prior years 5,844 1,878 2,723 Reductions for tax positions in prior years (67 ) (29 ) (1,973 ) Expiration of statute of limitations — (322 ) (469 ) Ending balance $ 122,823 $ 90,615 $ 69,052 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 2018 , 2017 and 2016 , the Company recognized $(2.5) million , $2.1 million and $1.6 million , respectively, of interest and penalties related to uncertain tax positions. Accrued interest and penalties related to unrecognized tax benefits totaled $4.6 million , $7.1 million and $5.0 million as of March 31, 2018 , April 1, 2017 , and April 2, 2016 , respectively. The unrecognized tax benefits of $122.8 million and accrued interest and penalties of $4.6 million at the end of fiscal 2018 are recorded on the Consolidated Balance Sheet as an $18.3 million long-term liability, with the balance reducing the carrying value of the gross deferred tax assets. 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 tax positions taken in prior years where the only uncertainty was related to the timing of the tax deduction. Income taxes payable of $60.0 million and $31.7 million as of March 31, 2018 , and April 1, 2017 , respectively, are included in "Other current liabilities" in the Consolidated Balance Sheets. Long term income taxes payable of $24.2 million as of March 31, 2018 , are included in "Other long-term liabilities" in the Consolidated Balance Sheets. RFMD's fiscal 2015 and TriQuint's calendar 2014 federal, North Carolina, and California tax returns and subsequent tax years remain open for examination. The federal tax return for the short period ended January 1, 2015 for RFMD is currently under examination by the Internal Revenue Service, and the Singapore tax return for calendar year 2012 is currently under examination by the Singapore tax authorities. An examination by taxing authorities of the Company's China subsidiary in Beijing of its calendar year 2013 through 2015 tax returns was completed in fiscal 2018 with minimal adjustments and returns for subsequent tax years remain open for examination. An examination by the German taxing authorities of the returns for calendar years 2013 through 2015 was completed during fiscal 2017 with minimal adjustments and returns for subsequent tax years remain open for examination. Tax attributes (including net operating loss and credit carryovers) arising in earlier fiscal years remain open to adjustment.

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 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 85.0% 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 31, 2018 , 4.6 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 0.5 million , 0.7 million and 0.4 million shares under the ESPP in fiscal years 2018 , 2017 and 2016 , respectively. For fiscal years 2018 , 2017 and 2016 , 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 2018 , 2017 and 2016 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 during the fiscal year and, if earned, generally 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. In fiscal 2018, each non-employee director was eligible to receive 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 2018 , stock-based compensation of $20.5 million was recognized upon the grant of 0.3 million 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 $68.2 million for fiscal 2018 , net of expense capitalized into inventory. For fiscal years 2017 and 2016 , the total pre-tax stock-based compensation expense recognized was $88.8 million and $139.5 million , respectively, net of expense capitalized into inventory. A summary of activity of the Company’s director and employee stock option plans follows: Shares Weighted- Weighted-Average Remaining Contractual Term (in years) Aggregate Outstanding as of April 1, 2017 4,177 $ 19.72 Granted — — Exercised (1,544) $ 19.07 Canceled (5) $ 41.86 Forfeited (5) $ 19.99 Outstanding as of March 31, 2018 2,623 $ 20.06 3.64 $ 132,217 Vested and expected to vest as of March 31, 2018 2,623 $ 20.06 3.64 $ 132,216 Options exercisable as of March 31, 2018 2,597 $ 19.79 3.64 $ 131,585 The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value, based upon the Company’s closing stock price of $70.45 as of March 29, 2018 (the last business day prior to the fiscal year end on March 31, 2018 ), 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. As of March 31, 2018 , total remaining unearned compensation cost related to unvested option awards was $0.3 million , which will be amortized over the weighted-average remaining service period of approximately 0.5 years. 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 2018 2017 2016 Expected volatility N/A N/A 42.8 % Expected dividend yield N/A N/A 0.0 % Expected term (in years) N/A N/A 5.7 Risk-free interest rate N/A N/A 1.6 % Weighted-average grant-date fair value of options granted during the period N/A N/A $ 32.62 The total intrinsic value of options exercised during fiscal 2018 , was $87.8 million . For fiscal years 2017 and 2016 , the total intrinsic value of options exercised was $81.0 million and $74.9 million , respectively. Cash received from the exercise of stock options and from participation in the employee stock purchase plan (excluding accrued unremitted employee funds) was approximately $57.5 million for fiscal 2018 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 assumes 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 1.6% for both stock options and restricted stock units. The following activity has occurred with respect to restricted stock unit awards: Shares Weighted-Average Balance at April 1, 2017 2,375 $ 53.00 Granted 998 68.67 Vested (1,059) 50.30 Forfeited (127) 57.73 Balance at March 31, 2018 2,187 $ 59.46 As of March 31, 2018 , total remaining unearned compensation cost related to unvested restricted stock units was $72.5 million , which will be amortized over the weighted-average remaining service period of approximately 1.2 years . The total fair value of restricted stock units that vested during fiscal 2018 was $73.2 million , based upon the fair market value of the Company’s common stock on the vesting date. For fiscal years 2017 and 2016 , the total fair value of restricted stock units that vested was $46.1 million and $60.2 million , respectively.

Equity [Abstract]
SHAREHOLDERS' EQUITY	STOCKHOLDERS’ EQUITY Stock Repurchase On November 5, 2015, the Company announced that its Board of Directors authorized a share repurchase program to repurchase up to $1.0 billion of the Company's outstanding common stock through November 4, 2016. On February 16, 2016, as part of the $1.0 billion share repurchase program, the Company entered into variable maturity accelerated share repurchase ("ASR") agreements (a $250.0 million collared agreement and a $250.0 million uncollared agreement) with Bank of America, N.A. For the upfront payment of $500.0 million , the Company received 3.1 million shares of its common stock under the collared agreement (representing 50% of the shares the Company would have repurchased assuming an average share price of $40.78 ) and 4.9 million shares of the Company's common stock under the uncollared agreement (representing 80% of the shares the Company would have repurchased assuming an average share price of $40.78 ). On March 10, 2016, the Company received an additional 2.0 million shares of its common stock under the collared agreement. Final settlements of the ASR agreements were completed during the first quarter of fiscal 2017 with 0.4 million shares received resulting in a total of 10.4 million shares of the Company's common stock repurchased under the ASR agreements. The shares were retired in the periods they were delivered, and the upfront payment was accounted for as a reduction to stockholders' equity in the Consolidated Balance Sheet in the period the payment was made. The Company reflected each ASR as a repurchase of common stock in the period delivered for purposes of calculating earnings per share. On November 3, 2016, the Company announced that its Board of Directors authorized a share repurchase program to repurchase up to $500.0 million of the Company's outstanding stock. Under this program, share repurchases are made in accordance with applicable securities laws on the open market or in privately negotiated transactions. The extent to which the Company repurchases its shares, the number of shares and the timing of any repurchases will depend on general market conditions, regulatory requirements, alternative investment opportunities and other considerations. The program does not require the Company to repurchase a minimum number of shares, does not have a fixed term, and may be modified, suspended or terminated at any time without prior notice. The program included approximately $150.0 million authorized on the $1.0 billion repurchase program that expired November 4, 2016. The Company repurchased 2.9 million shares, 4.1 million shares (inclusive of 0.4 million shares received under the ASR agreement) and 24.3 million shares (inclusive of 10.0 million shares received under the ASR agreement) of its common stock during fiscal years 2018 , 2017 and 2016 , respectively, at an aggregate cost of $219.9 million , $209.4 million and $1,300.0 million , respectively, in accordance with the share repurchase programs described above. As of March 31, 2018 , $162.1 million remains available for future repurchases under our current share repurchase program. Common Stock Reserved For Future Issuance At March 31, 2018 , the Company had reserved a total of approximately 15.7 million of its authorized 405.0 million shares of common stock for future issuance as follows (in thousands): Outstanding stock options under formal directors’ and employees’ stock option plans 2,623 Possible future issuance under Company stock incentive plans 6,254 Employee stock purchase plan 4,594 Restricted stock-based units granted 2,187 Total shares reserved 15,658

Segment Reporting [Abstract]
OPERATING SEGMENT AND GEOGRAPHIC INFORMATION	OPERATING SEGMENT AND GEOGRAPHIC INFORMATION The Company's operating segments as of March 31, 2018 are MP and IDP based on the organizational structure and information reviewed by the Company's Chief Executive Officer, who is the Company's chief operating decision maker ("CODM"), and these segments 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. MP is a leading global supplier of cellular RF and Wi-Fi solutions for a variety of mobile devices, including smartphones, notebook computers, wearables, tablets, and cellular-based applications for the IoT. Mobile device manufacturers and mobile network operators are adopting new technologies to address the growing demand for data-intensive, increasingly cloud-based distributed applications and for mobile devices with smaller form factors, improved signal quality, less heat and longer talk and standby times. New wireless communications standards are being deployed to utilize available spectrum more efficiently. Carrier aggregation is being implemented to support wider bandwidths, increase data rates and improve network performance. These trends increase the complexity of smartphones, require more RF content and place a premium on performance, integration, systems-level expertise, and product and technology portfolio breadth, all of which are MP strengths. MP offers a comprehensive product portfolio of BAW and SAW filters, power amplifiers ("PAs"), low noise amplifiers ("LNAs"), switches, multimode multi-band PAs and transmit modules, RF power management integrated circuits, diversity receive modules, antenna switch modules, antenna tuning and control solutions, modules incorporating PAs and duplexers and modules incorporating switches, PAs and duplexers. IDP is a leading global supplier of RF solutions with a diverse portfolio of solutions that "connect and protect," spanning communications and defense applications. These applications include high performance defense systems such as radar, electronic warfare and communication systems, Wi-Fi customer premises equipment for home and work, high speed connectivity in Long-Term Evolution and 5G base stations, cloud connectivity via data center communications and telecom transport, automotive connectivity and other IoT, including smart home solutions. IDP products include high power GaAs and GaN PAs, LNAs, switches, CMOS SoC solutions, premium BAW and SAW filter solutions and various multi-chip and hybrid assemblies. The “All other” category includes operating expenses such as stock-based compensation, amortization of intangible assets, acquisition and integration related costs, restructuring and disposal costs, start-up costs, (loss) gain on assets 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 intercompany 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): Fiscal Year 2018 2017 2016 Revenue: MP $ 2,181,161 $ 2,384,041 $ 2,083,334 IDP 788,495 644,653 523,512 All other (1) 3,880 3,880 3,880 Total revenue $ 2,973,536 $ 3,032,574 $ 2,610,726 Income from operations: MP $ 549,574 $ 554,001 $ 591,751 IDP 235,719 152,539 108,370 All other (715,011 ) (618,481 ) (688,153 ) Income from operations $ 70,282 $ 88,059 $ 11,968 Interest expense $ (59,548 ) $ (58,879 ) $ (23,316 ) Interest income 7,017 1,212 2,068 Other (expense) income (606 ) (3,087 ) 6,418 Income (loss) before income taxes $ 17,145 $ 27,305 $ (2,862 ) (1) "All other" revenue relates to royalty income that is not allocated to MP or IDP.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation 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. Certain items in the fiscal years 2017 and 2016 financial statements have been reclassified to conform to the fiscal 2018 presentation, such as restricted cash in accordance with Accounting Standards Update ("ASU") 2016-18.
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 31, 2018 , April 1, 2017 , and April 2, 2016 . Fiscal years 2018 and 2017 were 52-week years, and fiscal year 2016 was a 53-week year.
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. During the first quarter of fiscal 2018, the Company changed its accounting estimate for the expected useful lives of certain machinery and equipment. The Company evaluated its asset base and reassessed the estimated useful lives of certain machinery and equipment in connection with its implementation of several capital projects, including the migration of certain surface acoustic wave ("SAW") processes from 4-inch to 6-inch toolsets and certain bulk acoustic wave ("BAW") processes from 6-inch to 8-inch toolsets. Based on its ability to re-use equipment across generations of process technologies and historical usage trends, the Company determined that the expected useful lives for certain machinery and equipment should be increased by up to three years to reflect more closely the estimated economic lives of those assets. This change in estimate was applied prospectively effective for the first quarter of fiscal 2018 and resulted in a decrease in depreciation expense of $59.7 million for fiscal 2018. This decrease in depreciation expense for fiscal 2018 resulted in the following: (1) an increase in income from operations of $47.4 million ; (2) an increase in net income of $44.1 million ; (3) an improvement in earnings per share of $0.34 ; and (4) a reduction in inventory of $12.3 million .
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 31, 2018 and April 1, 2017 consisted of auction rate securities ("ARS"). 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 cost of available-for-sale securities is adjusted for premiums and discounts, with the amortization or accretion of such amounts 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 net realizable value (cost is based on standard cost, which approximates actual average cost). 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 and 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 was not significant during the periods presented.
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 ( $38.1 million as of March 31, 2018 and $55.4 million as of April 1, 2017 , which are reported on a net basis), precious metal reclaims submitted for payment and other miscellaneous items.
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 thirty-nine years . The Company capitalizes interest on borrowings related to eligible capital expenditures. Capitalized interest is added to the cost of qualified assets and depreciated together with that asset cost. 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 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. The Company periodically evaluates the period over which it expects to recover the economic value of the Company’s property and equipment, considering factors such as changes in machinery and equipment technology, the ability to re-use equipment across generations of process technology and historical usage trends. If the Company determines that the useful lives of its assets are shorter or longer than originally estimated, the rate of depreciation is adjusted to reflect the revised useful lives of the assets. The Company assesses property and equipment for impairment when events or changes in circumstances indicate that the carrying amount of its assets may not be recoverable. Factors that are considered in deciding when to perform an impairment review include an adverse change in the use of the Company’s assets or an expectation that the assets will be sold or otherwise disposed. 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. Assets identified as “held for sale” are recorded at the lesser of their carrying value or their fair market value less costs to sell. Impairment, if any, is based on the excess of the carrying amount over the fair value of those assets.
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. The Company accounts for goodwill and indefinite-lived intangible assets in accordance with the Financial Accounting Standards Board ("FASB") guidance, which requires annual testing for impairment or whenever events or circumstances make it more likely than not that an impairment may have occurred. The Company performs its annual impairment tests on the first day of the fourth quarter in each fiscal year. Indefinite-lived intangible assets consist 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 its impairment test, the Company is required to make assumptions and judgments, including 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 its results of operations. Goodwill Goodwill is allocated to the Company's reporting units based on the expected benefit from the synergies of the business combinations generating the underlying goodwill. As of March 31, 2018 , the Company's goodwill balance of $2,173.9 million is allocated between its Mobile Products ("MP") and Infrastructure and Defense Products ("IDP") reporting units. In fiscal years 2018 and 2017, the Company completed qualitative assessments of the fair value of its reporting units and concluded that goodwill was not impaired. For fiscal 2016, although there were no indicators of impairment, the Company opted to bypass the qualitative assessment and proceeded to perform fair value assessments of its reporting units (the first step of the quantitative impairment analysis) as the fair value of the reporting units had changed (due to the Business Combination) since the last time the Company performed a quantitative analysis. The quantitative assessments performed reaffirmed that there were no indicators of impairment for fiscal 2016. In performing these quantitative assessments, consistent with its historical approach, the Company used both the income and market approaches to estimate the fair value of its reporting units. The income approach involves discounting future estimated cash flows. The sum of the reporting unit cash flow projections was compared to the Company's market capitalization in a discounted cash flow framework to calculate an overall implied internal rate of return (or discount rate) for the Company. The Company's market capitalization was adjusted to a control basis assuming a reasonable control premium, which resulted in an implied discount rate. This implied discount rate serves as a baseline for estimating the specific discount rate for each reporting unit. The discount rate used is the value-weighted average of the Company's estimated cost of equity and debt (“cost of capital”) derived using both known and estimated customary market metrics. The Company's weighted average cost of capital is adjusted for each reporting unit to reflect a risk factor, if necessary, for each reporting unit. The Company performs sensitivity tests with respect to growth rates and discount rates used in the income approach. The Company believes the income approach is appropriate because it provides a fair value estimate based upon the respective reporting unit’s expected long-term operations and cash flow performance. The Company considered historical rates and current market conditions when determining the discount and growth rates used in its analysis. For fiscal 2016, the material assumptions used for the income approach were eight years of projected net cash flows and a long-term growth rate of 3% for both the MP and IDP reporting units. A discount rate of 15% and 16% was used for the MP and IDP reporting units, respectively. In applying the market approach, valuation multiples are derived from historical and projected operating data of selected guideline companies, which are evaluated and adjusted, if necessary, based on the strengths and weaknesses of the reporting unit relative to the selected guideline companies. The valuation multiples are then applied to the appropriate historical and/or projected operating data of the reporting unit to arrive at an indication of fair value. The Company believes the market approach is appropriate because it provides a fair value using multiples from companies with operations and economic characteristics similar to its reporting units. The Company weighted the results of the income approach and the results of the market approach at 50% each and for the MP and IDP reporting units, concluded that the fair value of the reporting units was determined to be substantially in excess of the carrying value, and as such, no further analysis was warranted. Under the income approach described above, the following indicates the sensitivity of key assumptions utilized in the assessment. A one percentage point decrease in the discount rate would have increased the fair value of the MP and IDP reporting units by approximately $660.0 million and $140.0 million , respectively, while a one percentage point increase in the discount rate would have decreased the fair value of the MP and IDP reporting units by approximately $560.0 million and $110.0 million , respectively. A one percentage point decrease in the long-term growth rate would have decreased the fair value of the MP and IDP reporting units by approximately $290.0 million and $50.0 million , respectively, while a one percentage point increase in the long-term growth rate would have increased the fair value of the MP and IDP reporting units by approximately $340.0 million and $70.0 million , respectively. Intangible Assets with Indefinite Lives 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 ("R&D") 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. During fiscal years 2018 , 2017 and 2016 , the Company completed and transferred into developed technology approximately $37.0 million , $220.0 million and $203.0 million , respectively, of IPRD. The Company performed a qualitative assessment of the remaining IPRD of $10.0 million during fiscal 2018 and concluded that IPRD was not impaired. 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 and trade names 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, 2015 and 2017 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, 2015 and 2017 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 three to six years. The fair value of trade names acquired in fiscal years 2015 and 2017 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 two to three years. The Company regularly reviews identified intangible assets to determine if facts and circumstances indicate that the useful lives have changed from the original estimate 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.
Accrued Liabilities	Accrued Liabilities The "Accrued liabilities" balance as of March 31, 2018 and April 1, 2017 includes accrued compensation and benefits of $96.7 million and $98.7 million , respectively, and interest payable of $23.1 million and $23.2 million , respectively.
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 5% 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, stock rotation, and scrap allowance 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 R&D work, royalty income, intellectual property ("IP") revenue, and service revenue. These agreements are collectively less than 1% of consolidated annual revenue. 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 upon delivery of the IP 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 R&D costs to expense as incurred.
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 states 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 in "Other receivables" in 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 for each tax jurisdiction 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 that some portion or all of its deferred tax assets will not be realized. A more likely than not 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 current intent and policy to invest the earnings of foreign subsidiaries indefinitely outside the U.S., except for Qorvo International Pte. Ltd. in Singapore. Accordingly, the Company does not record a deferred tax liability for U.S. income taxes on unremitted foreign earnings of other foreign subsidiaries.
Stock-Based Compensation	Stock-Based Compensation Under FASB Accounting Standards Codification ("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 31, 2018 , total remaining unearned compensation cost related to unvested restricted stock units and options was $72.8 million , which will be amortized over the weighted-average remaining service period of approximately 1.2 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 income (expense)” in the Consolidated Statements of Operations.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Pronouncements Not Yet Effective In January 2017, the FASB issued ASU 2017-04, "Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." The new guidance simplifies the subsequent measurement of goodwill by eliminating the second step from the quantitative goodwill impairment test. The Company will continue to have the option to perform a qualitative assessment to determine if a quantitative goodwill impairment test is necessary. The new standard will become effective for the Company beginning in fiscal 2021 with early adoption permitted. The Company does not believe it will have a significant impact on its consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business." The new guidance clarifies the definition of a business and provides further guidance for evaluating whether a transaction will be accounted for as an acquisition of an asset or a business. The new standard will become effective for the Company beginning in the first quarter of fiscal 2019 with early adoption permitted. The update should be applied prospectively. The Company does not believe it will have a significant impact on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the FASB’s Emerging Issues Task Force)." The new guidance addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The new standard will become effective for the Company beginning in the first quarter of fiscal 2019. The Company does not believe it will have a significant impact on its consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." The new guidance requires entities to use a current lifetime expected credit loss methodology to measure impairments of certain financial instruments. It also modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The new standard will become effective for the Company beginning in the first quarter of fiscal 2021 with early adoption permitted. The Company does not believe it will have a significant impact on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." The new guidance requires lessees to recognize a right-of-use asset and a lease liability for all leases with a term longer than 12 months, including those previously described as operating leases. Consistent with current U.S. generally accepted accounting principles ("GAAP"), the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee will primarily depend on its classification as a finance or operating lease. The new guidance will become effective for the Company in the first quarter of fiscal 2020. The Company expects the valuation of the right-of-use assets and lease liabilities, for leases previously described as operating leases, to be the present value of its forecasted future lease commitments. The Company is continuing to assess the overall impacts of the new standard, including the discount rate to be applied in these valuations. In January 2016, the FASB issued ASU 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." The new guidance will affect the accounting for equity investments, financial liabilities measured under the fair value option and presentation and disclosure requirements for financial instruments. In addition, the FASB clarified guidance related to the assessment of valuation allowances when recognizing deferred tax assets related to unrealized losses on available-for-sale debt securities. The new standard is effective for the Company beginning in the first quarter of fiscal 2019. The Company does not believe it will have a significant impact on its consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)," with several amendments subsequently issued. The new guidance provides an updated framework for revenue recognition, resulting in a single revenue model to be applied by reporting companies under U.S. GAAP. Under the new model, recognition of revenue occurs when a customer obtains control of promised goods or services in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Additional disclosures will be required regarding the nature, amount, timing and uncertainty of cash flows. The Company will adopt the standard in the first quarter of fiscal 2019 using the modified retrospective approach, under which the cumulative effect of adoption is recognized at the date of initial application. The Company has evaluated the impact of the standard and does not anticipate that the adoption of this standard will have a material impact on its consolidated financial statements. The Company is implementing changes to its accounting policies, internal controls and disclosures to support the new standard; however, these changes are not expected to be material. Accounting Pronouncements Recently Adopted In March 2018, the FASB issued ASU 2018-05, "Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118." The amendments incorporate into the ASC the recent SEC guidance related to the income tax accounting implications of the Tax Cuts and Jobs Act (the "Tax Act"). See Note 12 for further disclosures. In May 2017, the FASB issued ASU 2017-09, "Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting." The new guidance clarifies when modification accounting in Topic 718 should be applied to changes to the terms or conditions of a share-based payment award. The Company elected to early-adopt the standard in the first quarter of fiscal 2018 with no impact on its consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force)." The new guidance requires that restricted cash and restricted cash equivalents be included in cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown in the statement of cash flows. The Company adopted the provisions of ASU 2016-18 in the second quarter of fiscal 2018 using the retrospective transition method. The adjustment to reclassify restricted cash for each period presented was less than $1.0 million . In October 2016, the FASB issued ASU 2016-16, "Income Taxes (Topic 740), Intra-Entity Transfers of Assets Other Than Inventory." The new guidance requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. The Company elected to early-adopt the standard in the first quarter of fiscal 2018 using the modified retrospective method (which resulted in a cumulative adjustment to retained earnings of $1.2 million as of the beginning of the period of adoption). During fiscal 2018, the Company recognized a tax expense of $6.9 million related to transfers of intra-entity assets. In March 2016, the FASB issued ASU 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting." The new guidance simplifies certain aspects of accounting for share-based payment transactions, including income tax consequences, forfeitures, classification of awards on the balance sheet and presentation on the statement of cash flows, and became effective for the Company in the first quarter of fiscal 2018. The Company recognized a cumulative-effect adjustment to reduce the Company's accumulated deficit by $36.7 million with a corresponding increase to deferred tax assets for the federal and state net operating losses attributable to excess tax benefits that had not been previously recognized. All excess tax benefits and deficiencies in the current and future periods will be recognized as income tax expense in the Company’s Consolidated Statement of Operations in the reporting period in which they occur. This will result in increased volatility in the Company’s effective tax rate. During fiscal 2018, the Company recognized a discrete tax benefit of $12.2 million related to the excess tax benefits from stock-based compensation. The Company also elected to prospectively adopt the provision that requires excess tax benefits to be presented within operating activities in the statement of cash flows and no prior periods have been restated as a result of the adoption. The Company has continued its existing practice of estimating expected forfeitures in determining compensation cost. In March 2016, the FASB issued ASU 2016-07, "Investments-Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting." The new guidance eliminates the requirement to retrospectively apply the equity method of accounting when an investment previously accounted for under the cost basis qualifies for the equity method of accounting. The Company adopted ASU 2016-07 in the first quarter of fiscal 2018 with no impact on its consolidated financial results. In July 2015, the FASB issued ASU 2015-11, "Inventory (Topic 330): Simplifying the Measurement of Inventory." The new guidance changes the measurement principle for inventory from the lower of cost or market to the lower of cost and net realizable value. ASU 2015-11 defines net realizable value as the estimated selling price in the ordinary course of business less reasonably predictable costs to completion, transportation, or disposal. The Company adopted ASU 2015-11 in the first quarter of fiscal 2018 with no significant impact on its consolidated financial statements.
Operating Segment	The Company's operating segments as of March 31, 2018 are MP and IDP based on the organizational structure and information reviewed by the Company's Chief Executive Officer, who is the Company's chief operating decision maker ("CODM"), and these segments 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.
Fair Value Measurement	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.
