On April 29, 2016, the Company completed the acquisition of GreenPeak Technologies, B.V. ("GreenPeak"), a leader in ultra-low power, short range radio frequency ("RF") communication technology, for a purchase price of $118.7 million. The acquisition expanded the Company's offerings to include integrated RF solutions and systems-on-a-chip ("SoCs") for the connected home and the Internet of Things ("IoT"). The acquisition resulted in initial goodwill of $39.2 million and an increase in intangible assets of $82.1 million. A Business Combination adjustment reduced goodwill by $1.0 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).

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

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 United States to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and outside the United States pursuant to Regulation S under the Securities Act. The carrying value of issuance costs related to the Notes was $11.1 million as of December 31, 2016 and $11.9 million as of April 2, 2016, and is presented on the Condensed Consolidated Balance Sheets as a direct deduction of Long-term debt.

The Notes were issued pursuant to an indenture, dated as of November 19, 2015 (the “Indenture”), by and among the Company, the Company’s domestic subsidiaries that guarantee the Company’s obligations under its revolving credit facility, as guarantors (the “Guarantors”), and MUFG Union Bank, N.A., as trustee. The Company used the net proceeds of the offering of the Notes for general corporate purposes, including share repurchases and merger and acquisition activity.

Interest is payable 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. For the three and nine months ended December 31, 2016, the Company recognized $17.4 million and $52.2 million, respectively, of interest expense related to the Notes, which was offset by $3.6 million and $9.0 million, respectively, of interest capitalized to property and equipment. For the three and nine months ended January 2, 2016, the Company recognized $8.3 million of interest expense related to the Notes, which was offset by $1.6 million of interest capitalized to property and equipment. Interest on both series of Notes is payable semi-annually on June 1 and December 1 of each year, and commenced on June 1, 2016. Interest paid on the Notes during the three and nine months ended December 31, 2016 was $34.5 million and $71.2 million, respectively.

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).

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).

The Indenture contains 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.

In connection with the offering of the Notes, the Company agreed to provide the holders of the Notes with an opportunity to exchange the Notes for registered notes having terms substantially identical to the Notes. 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.

The 2023 Notes and the 2025 Notes are traded over the counter and their fair values as of December 31, 2016, of $495.6 million and $609.5 million, respectively (compared to carrying values of $450.0 million and $550.0 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 $465.8 million and $581.6 million, respectively, as of April 2, 2016.

Credit Agreement

On April 7, 2015, the Company and the Guarantors entered into a five-year unsecured senior credit facility with Bank of America, N.A., as administrative agent (in such capacity, the “Administrative Agent”), swing line lender, and L/C issuer, and a syndicate of lenders (the “Credit Agreement”). The Credit Agreement includes a $300.0 million revolving credit facility, which 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 any time and from time to time, that the revolving credit facility be increased by an amount not to exceed $150.0 million. The revolving 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. During the nine months ended December 31, 2016, there were no borrowings under the revolving credit facility. The Company had no outstanding amounts under the Credit Agreement as of December 31, 2016 and April 2, 2016.

At the Company’s option, loans under the Credit Agreement will 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 swing line loans will bear interest at a rate equal to the Applicable Rate plus the Base Rate. The Eurodollar Base Rate is the rate per annum equal to the London Interbank Offered Rate, as published by Bloomberg, for dollar deposits for interest periods of one, two, three or six months, as selected by the Company. The Applicable Rate for Eurodollar Rate loans ranges from 1.50% per annum to 2.00% per annum. The Applicable Rate for Base Rate loans ranges from 0.50% per annum to 1.00% per annum. Interest for Eurodollar Rate loans 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.

The Credit Agreement contains various conditions, covenants and representations with which the Company must be in compliance in order to borrow funds and to avoid an event of default, including financial covenants that the Company must maintain. On November 12, 2015, the Credit Agreement was amended to increase the size of certain of the negative covenant baskets and the threshold for certain negative covenant incurrence-based permissions and to raise the consolidated leverage ratio test from 2.50 to 1.00 to 3.00 to 1.00 as of the end of any fiscal quarter. The Company must also maintain a consolidated interest coverage ratio of not less than 3.00 to 1.00 as of the end of any fiscal quarter.

The Credit Agreement also contains customary events of default, and the occurrence of an event of default will increase the applicable rate of interest by 2.00% and could result in the termination of commitments under the revolving credit facility, the declaration that all outstanding loans are due and payable in whole or in part and the requirement of cash collateral deposits in respect of outstanding letters of credit. Outstanding amounts are due in full on the maturity date of April 7, 2020 (with amounts borrowed under the swing line option due in full no later than ten business days after such loan is made).

Income Taxes	9 Months Ended
Income Taxes	Dec. 31, 2016
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Income Tax Expense The Company’s provision for income taxes for the three and nine months ended December 31, 2016 and January 2, 2016 has been calculated by applying an estimate of the annual effective tax rate for the full fiscal year to “ordinary” income or loss (pre-tax income or loss excluding unusual or infrequently occurring discrete items) for the three and nine months ended December 31, 2016 and January 2, 2016. The Company’s income tax expense was $123.2 million and $137.1 million for the three and nine months ended December 31, 2016, respectively, and the Company's income tax (benefit) expense was $(9.9) million and $4.5 million for the three and nine months ended January 2, 2016, respectively. The Company’s effective tax rate was 276.6% and 212.2% for the three and nine months ended December 31, 2016, respectively, and 47.0% and (3,183.0)% for the three and nine months ended January 2, 2016, respectively. The Company's effective tax rate for both the third quarter of fiscal 2017 and the third quarter of fiscal 2016 differed from the statutory rate primarily due to tax rate differences in foreign jurisdictions, state income taxes, domestic tax credits generated, changes in unrecognized tax benefits, and the timing of when income and loss is recognized in the various tax jurisdictions. Income taxes payable of $122.8 million and $29.9 million as of December 31, 2016 and April 2, 2016, respectively, are included in "Other current liabilities" on the Company's Condensed Consolidated Balance Sheets. Deferred Taxes A valuation allowance remained against certain domestic and foreign net deferred tax assets as it is more likely than not that the related deferred tax assets will not be realized. The Company has domestic federal and state tax net operating loss (“NOLs”) carry-forwards that expire in fiscal years 2017 to 2036 if unused. The use of the NOLs that were acquired in prior year acquisitions is subject to certain annual limitations under Internal Revenue Code Section 382 and similar state income tax provisions. Uncertain Tax Positions The Company’s gross unrecognized tax benefits increased from $69.1 million as of the end of fiscal 2016 to $86.0 million as of the end of the third quarter of fiscal 2017, due to a $16.9 million increase primarily related to tax positions taken with respect to the current fiscal year.

The estimated fair value of available-for-sale securities was based on the prevailing market values on December 31, 2016 and April 2, 2016. The Company determines the cost of an investment sold based on the specific identification method.

There were no gross realized gains and insignificant gross realized losses recognized on available-for-sale securities for the three and nine months ended December 31, 2016. The gross realized gains and losses realized on available-for-sale securities for the three months ended January 2, 2016 were insignificant. There were $4.0 million of gross realized gains and insignificant gross realized losses recognized on available-for-sale securities for the nine months ended January 2, 2016.

There were no unrealized losses on available-for-sale securities in a continuous loss position for fewer than 12 months as of December 31, 2016, and as of April 2, 2016, such unrealized losses were insignificant. Unrealized losses on available-for-sale securities in a continuous loss position for 12 months or greater were $0.4 million as of December 31, 2016 and April 2, 2016.

The aggregate amount of available-for-sale securities in an unrealized loss position at December 31, 2016 was $1.7 million, with $0.4 million in unrealized losses. The aggregate amount of available-for-sale securities in an unrealized loss position at April 2, 2016 was $55.6 million, with $0.4 million in unrealized losses.

During the first quarter of fiscal 2017, our investments in commercial paper and U.S. government treasury bills matured and a portion of the proceeds was used for the GreenPeak acquisition.

Other Investments

On August 4, 2015, the Company invested $25.0 million to acquire shares of Series F Preferred Stock of Cavendish Kinetics Limited, a private limited company incorporated in England and Wales. This investment is accounted for as a cost method investment and classified in "Long-term investments" on the Company's Condensed Consolidated Balance Sheets.

Fair Value of Financial Instruments

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

Recurring Fair Value Measurements

The fair value of the financial assets measured at fair value on a recurring basis was determined using the following levels of inputs as of December 31, 2016 and April 2, 2016 (in thousands):

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

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

(3) The Company's 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 assets deferred by the participants in the “Other current assets” and “Other non-current assets” line items of its Condensed 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 Condensed Consolidated Balance Sheets.

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 5 for the fair value of the Company's long-term debt.

Stock Repurchases	9 Months Ended
Stock Repurchases	Dec. 31, 2016
Equity [Abstract]
STOCK REPURCHASES	STOCK REPURCHASES On November 3, 2016, the Company announced that its Board of Directors authorized a new share repurchase program to repurchase up to $500.0 million of the Company's outstanding stock. Under this program, share repurchases will be 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 and does not have a fixed term, and may be modified, suspended or terminated at any time without prior notice. During the three and nine months ended December 31, 2016, the Company repurchased approximately 1.3 million shares and 2.9 million shares of its common stock for approximately $67.1 million and $158.5 million, respectively. As of December 31, 2016, $432.9 million remains available for repurchases under our current share repurchase program. During the three and nine months ended January 2, 2016, the Company repurchased approximately 4.6 million shares and 14.3 million shares for approximately $250.0 million and $800.0 million, respectively, under prior share repurchase programs.

Recent Accounting Pronouncements	9 Months Ended
Recent Accounting Pronouncements	Dec. 31, 2016
New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTS Accounting Pronouncements Not Yet Effective 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 the inclusion of restricted cash along with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The new standard will become effective for the Company beginning in the first quarter of fiscal year 2019 with early adoption permitted. The Company does not believe it will have a significant impact on its consolidated financial statements. In October 2016, the FASB issued ASU 2016-16, "Income Taxes (Topic 740), Intra-Entity Transfers of Assets Other Than Inventory," which requires the recognition of the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. The new standard will become effective for the Company in the first quarter of fiscal year 2019 with early adoption permitted. The Company is currently evaluating the effects this new guidance will have 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 year 2019 with early adoption permitted. The Company is currently evaluating the effects the new guidance will have 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 year 2021 with early adoption permitted. The Company does not believe it will have a significant impact on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting." The new guidance will simplify 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. The new standard will become effective for the Company beginning in the first quarter of fiscal 2018. The Company is currently evaluating the effects this new guidance will have on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." The new standard will revise the current guidance for lessees, lessors and sale-leaseback transactions. Under the new guidance, substantially all lessees will now recognize a right-of-use asset and a lease liability for all of their leases with terms greater than 12 months even if the lease is an operating lease. Consistent with current GAAP, the recognition, measurement, and presentation of expenses and cash flow arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. The new guidance becomes effective for the Company in the first quarter of fiscal 2020 with early adoption permitted. The Company is currently evaluating the effects this new guidance will have on its consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." This new standard 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 July 2015, the FASB issued ASU 2015-11, "Inventory (Topic 330): Simplifying the Measurement of Inventory." Entities that measure their inventory other than pursuant to the last-in, first-out and retail inventory methods will measure their inventory at the lower of cost or net realized value. Net realized value is the estimated selling price in the ordinary course of business less reasonably predictable costs to completion, transportation, or disposal. Currently, inventory is required to be measured at the lower of cost or market where market could be the replacement cost, net realizable value, or net realizable value less an approximated normal profit margin. The Company will adopt the provisions of this standard in the first quarter of fiscal 2018, and is currently evaluating the impact on its consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)" that amends existing guidance on revenue recognition. The new guidance is based on principles that an entity will recognize revenue to depict the transfer of goods and services to customers at an amount the entity expects to be entitled to in exchange for those goods and services. The guidance requires additional disclosures regarding the nature, amount, timing, and uncertainty of cash flows and both qualitative and quantitative information about contracts with customers and applied significant judgments. The FASB has issued several amendments to the new guidance. In August 2015, it delayed the effective date for adoption by one year. In March 2016, additional guidance was issued that clarifies the principal versus agent considerations within the new revenue standard. In April, 2016, additional guidance was issued that clarifies the identification of distinct performance obligations in a contract as well as clarifies the accounting for licenses of intellectual property. In May 2016, additional guidance was issued related to transition, collectibility, non-cash consideration and the presentation of sales and other similar taxes. In December 2016, additional guidance was issued for technical corrections and improvements to Topic 606 and other Topics amended by Update 2014-09. The new amended guidance will become effective for the Company in the first quarter of fiscal 2019, using one of two retrospective methods of adoption. The Company has not determined which method it will adopt and is evaluating the effects the new guidance will have on its consolidated financial statements. Accounting Pronouncements Recently Adopted In April 2015, the FASB issued ASU 2015-05, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Fees Paid in a Cloud Computing Arrangement" which provided additional guidance to customers about whether a cloud computing arrangement includes a software license. Under this guidance, if a cloud computing arrangement contains a software license, customers should account for the license element of the arrangement in a manner consistent with the acquisition of other software licenses. If the arrangement does not contain a software license, customers should account for the arrangement as a service contract. The Company adopted the provisions of this standard in the first quarter of fiscal 2017, and there was no impact on its condensed consolidated financial statements. In September 2015, the FASB issued ASU 2015-16, "Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments." This standard requires an acquirer in a business combination to recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The effect on earnings of changes in depreciation, amortization or other income effects, as a result of the change in provisional amounts, are to be included in the same period’s financial statements, calculated as if the accounting had been completed at the acquisition date. The amendments in this update became effective for the Company beginning in the first quarter of fiscal 2017 and will be applied prospectively to adjustments to provisional amounts that occur in the future.

Operating Segment Information

Segment Reporting [Abstract]

OPERATING SEGMENT INFORMATION

The Company’s operating segments as of December 31, 2016 are Mobile Products (MP) and Infrastructure and Defense Products (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 (or 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 RF solutions that perform various functions in the increasingly complex cellular radio front end section of smartphones and other cellular devices. These RF solutions are required in fourth generation (“4G”) data-centric devices operating under Long-Term Evolution (“LTE”) 4G networks, as well as third generation (“3G”) and second generation mobile devices. These solutions include complete RF front end modules that combine high-performance filters, power amplifiers (“PAs”), low noise amplifiers (“LNAs”) and switches, PA modules, transmit modules, antenna control solutions, antenna switch modules, diversity receive modules and envelope tracking power management devices. MP supplies its broad portfolio of RF solutions into a variety of mobile devices, including smartphones, notebook computers, wearables, tablets and cellular-based applications for the IoT, including the connected car.

IDP is a leading global supplier of RF solutions that support diverse global applications, including ubiquitous high-speed network connectivity to the cloud, data center communications, rapid internet connectivity throughout the home and workplace, and upgraded military capabilities across the globe. These RF solutions enhance performance and reduce complexity in cellular base stations, optical long haul, data center and metro networks, WiFi networks, cable networks, and emerging fifth generation (“5G”) wireless networks. Products include high power gallium arsenide (“GaAs”) and gallium nitride (“GaN”) PAs, LNAs, switches, RF filter solutions, CMOS system-on-a-chip (“SoC”) solutions and various multichip and hybrid assemblies. IDP market-leading RF solutions for defense and aerospace upgrade communications and radar systems for air, land and sea. IDP RF solutions for the IoT enable the connected car and an array of industrial applications, and serve the home automation market with SoC solutions based on ZigBee and Bluetooth Smart technologies. During the first quarter of fiscal 2017, the Company acquired GreenPeak, a leader in ultra-low power, short range RF communication technology. The acquisition expanded the Company's offerings to include integrated RF solutions and SoCs for the connected home and the IoT.

The “All other” category includes operating expenses such as stock-based compensation, amortization of intangible assets, acquisition and integration related costs, acquired inventory step-up and revaluation, intellectual property rights (IPR) litigation (costs) settlement, restructuring and disposal costs, start-up costs, gain (loss) 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):

Consolidating Financial Information [Abstract]

Consolidating Financial Information [Text Block]

CONSOLIDATING FINANCIAL INFORMATION

As discussed in Note 5, the Notes were issued pursuant to the Indenture by and among the Company, the Company's domestic subsidiaries that guarantee the Company's obligations under its revolving credit facility, as guarantors, and MUFG Union Bank, N.A., as trustee. The Notes are fully and unconditionally guaranteed on a joint and several basis by each guarantor subsidiary, each of which is a direct or indirect wholly owned subsidiary of the Company. A guarantor subsidiary’s guarantee can be released in certain customary circumstances.

In accordance with Rule 3-10 of Regulation S-X, the following presents the condensed consolidating financial information separately for:


(i)	the Company, the issuer of the Notes;


(ii)	the guarantor subsidiaries, on a combined basis, as specified in the Indenture;


(iii)	the non-guarantor subsidiaries, on a combined basis;


(iv)	consolidating entries and eliminations representing adjustments to (a) eliminate intercompany transactions between or among the Company, the guarantor subsidiaries and the non-guarantor subsidiaries, (b) eliminate intercompany profit in inventory, (c) eliminate the investments in the Company’s subsidiaries and (d) record consolidating entries; and


(v)	the Company, on a consolidated basis.

Each entity in the condensed consolidating financial information follows the same accounting policies as described in the consolidated financial statements, except for the use by the Company and guarantor subsidiaries of the equity method of accounting to reflect ownership interests in subsidiaries that are eliminated upon consolidation. The financial information may not necessarily be indicative of the financial position, results of operations, comprehensive income (loss), and cash flows, had the Company, guarantor or non-guarantor subsidiaries operated as independent entities.

Basis of Presentation and Significant Accounting Policies (Policies)	9 Months Ended
	Dec. 31, 2016
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Income Tax Policy	The Company’s provision for income taxes for the three and nine months ended December 31, 2016 and January 2, 2016 has been calculated by applying an estimate of the annual effective tax rate for the full fiscal year to “ordinary” income or loss (pre-tax income or loss excluding unusual or infrequently occurring discrete items) for the three and nine months ended December 31, 2016 and January 2, 2016
Fair Value Measurements Policy	On a quarterly basis, the Company measures the fair value of its marketable securities, which are comprised of U.S. government/agency securities, corporate debt, auction rate securities (ARS), and money market funds. Marketable securities are reported at fair value in "Cash and cash equivalents," "Short-term investments" and "Long-term investments" on the Company’s Condensed Consolidated Balance Sheets. The related unrealized gains and losses are included in "Accumulated other comprehensive loss," a component of stockholders’ equity, net of tax.
Operating Segment Policy	The Company’s operating segments as of December 31, 2016 are Mobile Products (MP) and Infrastructure and Defense Products (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 (or 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.

- Definition
