Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Nature of Business . Integrated Device Technology, Inc. (IDT or the Company) designs, develops, manufactures and markets a broad range of integrated circuits for the advanced communications, computing and consumer industries. Basis of Presentation . The Company's fiscal year is the 52 or 53 week period ending on the Sunday closest to March 31. In a 52 week year, each fiscal quarter consists of 13 weeks. In a 53 week year, the additional week is usually added to the third quarter, making such quarter consist of 14 weeks. The first quarters of fiscal 2016 and fiscal 2015 were 13 week periods. Principles of Consolidation . The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All inter-company accounts and transactions have been eliminated. Use of Estimates . The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Significant Accounting Policies . For a description of significant accounting policies, see Note 1, Summary of Significant Accounting Policies to the consolidated financial statements included in the Company's annual report on Form 10-K for the fiscal year ended March 29, 2015. There have been no material changes to the Company's significant accounting policies since the filing of the annual report on Form 10-K. In the opinion of management, these condensed consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, which are necessary for the fair presentation of the condensed consolidated financial statements, for the interim period. Recent Accounting Pronouncements Accounting Pronouncements Not Yet Effective for Fiscal 2016 In July 2015, the Financial Accounting Standards Board (FASB) issued guidance applying to inventory measured using any other method other than last-in, last-out method. Under this guidance, inventory is measured at the lower of cost and net realizable value. The net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The guidance is applied prospectively and is effective for the Company in its first quarter of fiscal 2018. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on the Company’s financial statements and related disclosures. In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements - Going Concern, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. This standard sets forth management’s responsibility to evaluate, each reporting period, whether there is substantial doubt about an entity’s ability to continue as a going concern, and if so, to provide related footnote disclosures. The standard is effective for annual reporting periods ending after December 15, 2016 and interim periods within annual periods beginning after December 15, 2016. The Company does not believe that the adoption of this guidance will have any material impact on its financial position or results of operations. On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The standard permits the use of either the retrospective or cumulative effect transition method. On July 9, 2015, the FASB decided to delay the effective date by one year to December 15, 2017 for annual periods beginning after that date. The FASB also decided to allow early adoption of the standard, but not before the original effective date of December 15, 2016. The Company is currently evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.

Net Income Per Share	Jun. 28, 2015
Earnings Per Share [Abstract]
Net Income Per Share	Net Income Per Share Basic net income per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net income per share is computed using the weighted-average number of common and dilutive potential common shares outstanding during the period. Potential common shares include employee stock options and restricted stock units. For purposes of computing diluted net income per share, weighted average potential common shares do not include potential common shares that are anti-dilutive under the treasury stock method. The following table sets forth the computation of basic and diluted net income per share from continuing operations: Three Months Ended (in thousands, except per share amounts) June 28, June 29, Numerator (basic and diluted): Net income from continuing operations $ 38,720 $ 17,111 Denominator: Weighted average common shares outstanding, basic 148,396 149,283 Dilutive effect of employee stock options and restricted stock units 5,362 4,458 Weighted average common shares outstanding, diluted 153,758 153,741 Basic net income per share from continuing operations $ 0.26 $ 0.11 Diluted net income per share from continuing operations $ 0.25 $ 0.11 Potential dilutive common shares of 0.3 million and 0.7 million pertaining to employee stock options and restricted stock units were excluded from the calculation of diluted earnings per share for the three months ended June 28, 2015 and June 29, 2014 , respectively, because the effect would have been anti-dilutive.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations High-Speed Converter (“HSC”) Business In fiscal 2014, the Company initiated a project to divest its HSC business and has classified the related assets, as held for sale. The HSC business included the assets of NXP B.V.’s Data Converter Business and Alvand Technologies, Inc., which were acquired in fiscal 2013. On May 30, 2014, the Company completed the sale of certain assets related to the Alvand portion of the HSC business to a buyer pursuant to an Asset Purchase Agreement. Upon the closing of the transaction, the buyer paid the Company $18.0 million in cash consideration, of which $2.7 million has been held in an escrow account for a period of 18 months . The Company recorded a gain of $16.8 million in discontinued operations related to this divestiture during the first quarter of fiscal 2015. The following table summarizes the components of the gain (in thousands): Amount Cash proceeds from sale (including amounts held in escrow) $ 18,000 Less book value of assets sold and direct costs related to the sale: Intangible assets (990 ) Transaction and other costs (170 ) Gain on divestiture $ 16,840 Following the sale of assets related to the Alvand portion of the HSC business, the business had remaining long-lived assets classified as held for sale amounting to $8.5 million , which consisted of $2.9 million in fixed assets and $5.6 million in intangible assets. The Company evaluated the carrying value of the disposal group and determined that it exceeded its estimated fair value based on estimated selling price less cost to sell. Accordingly, total impairment charge of $8.5 million was recorded as loss from discontinued operations in the Condensed Consolidated Statement of Operations in the first quarter of fiscal 2015. As of March 29, 2015, all long-lived assets related to the HSC business were fully impaired. On April 27, 2015, the Company completed the sale of the remaining HSC business to eSilicon Corporation (“eSilicon”), for $1.5 million which will be paid on or before April 27, 2017. In connection with the sale, the Company entered into an Exclusive Intellectual Property License Agreement with eSilicon, whereby the Company provided an exclusive license to eSilicon to develop, manufacture, sell and maintain HSC products. In connection with the sale, the Company and eSilicon also entered into a Transition Services Agreement, whereby the Company will provide certain transition services over a specific period from the effective date of the sale. The transition services do not represent significant continuing involvement of the Company in the HSC business. As of June 28, 2015, the Company had a receivable of $1.5 million representing uncollected proceeds from the sale that was included under Other Assets on the Condensed Consolidated Balance Sheet. Given the term of the sale, the Company deferred the gain from this divestiture and will recognize it into discontinued operations when collectibility becomes certain. The following table summarizes the components of the deferred gain which was included under Other Long-term Liabilities on the Condensed Consolidated Balance Sheet as of June 28, 2015: (in thousands) Amount Sale price $ 1,500 Less book value of assets sold (115 ) Deferred gain on divestiture $ 1,385 The HSC business was included in the Company’s Communications reportable segment. For financial statements purposes, the results of operations for the HSC business have been segregated from those of the continuing operations and are presented in the Company's condensed consolidated financial statements as discontinued operations. The results of the HSC business for the three months ended June 28, 2015 and June 29, 2014 were as follows (in thousands): Three Months Ended June 28, 2015 June 29, 2014 Revenues $ 176 $ 1,006 Cost of revenues (477 ) (605 ) Long-lived assets impairment — (8,471 ) Operating expenses (246 ) (4,083 ) Gain on divestiture — 16,840 Income tax benefit (provision) (15 ) 45 Net income (loss) from discontinued operations $ (562 ) $ 4,732

Corporate bonds include bank-issued securities that are guaranteed by the Federal Deposit Insurance Corporation (FDIC). The securities in Level 1 are highly liquid and actively traded in exchange markets or over-the-counter markets. Level 2 fixed income securities are priced using quoted market prices for similar instruments, non-binding market prices that are corroborated by observable market data. All of the Company’s available-for-sale investments are subject to a periodic impairment review. Investments are considered to be impaired when a decline in fair value is judged to be other-than-temporary. The Company did not record any impairment charges related to its available-for-sale investments in the three months ended June 28, 2015 and June 29, 2014 .

As of June 28, 2015 , the unrealized losses on the Company’s available-for-sale investments represented an insignificant amount in relation to its total available-for-sale portfolio. Substantially all of the Company’s unrealized losses on its available-for-sale marketable debt instruments can be attributed to fair value fluctuations in an unstable credit environment that resulted in a decrease in the market liquidity for debt instruments. Because the Company has the ability to hold these investments until a recovery of fair value, which may be maturity, the Company did not consider these investments to be other-than-temporarily impaired at June 28, 2015 and March 29, 2015 . Non-marketable Equity Securities In the quarter ended December 28, 2014, the Company purchased common stock of a privately-held company for $4 million . This investment (included under Other Assets on the Condensed Consolidated Balance Sheets) is accounted for as a cost-method investment, as the Company owns less than 20% of the voting securities and does not have the ability to exercise significant influence over operating and financial policies of the entity. The Company did not record any impairment charge for this investment during the three months ended June 28, 2015.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Employee Compensation	Stock-Based Employee Compensation Equity Incentive Programs The Company currently issues awards under two equity-based plans in order to provide additional incentive and retention to directors and employees who are considered to be essential to the long-range success of the Company. These plans are further described below. 2004 Equity Plan (2004 Plan) Options granted by the Company under the 2004 Plan generally expire seven years from the date of grant and generally vest over a four -year period from the date of grant, with one-quarter of the shares of common stock vesting on the 1 year anniversary of the grant date and the remaining shares vesting monthly for the 36 months thereafter. The exercise price of the options granted by the Company under the 2004 Plan shall not be less than 100% of the fair market value for a common share subject to such option on the date the option is granted. Full value awards made under the 2004 Plan shall become vested over a period of not less than 3 years (or, if vesting is performance-based, over a period of not less than one year) following the date such award is made; provided, however, that full value awards that result in the issuance of an aggregate of up to 5% of common stock available under the 2004 Plan may be granted to any one or more participants without respect to such minimum vesting provisions. As of June 28, 2015 , there were 8.5 million shares available for future grant under the 2004 Plan. Compensation Expense The following table summarizes stock-based compensation expense by line items appearing in the Company’s Condensed Consolidated Statement of Operations: Three Months Ended (in thousands) June 28, June 29, Cost of revenue $ 683 $ 316 Research and development 3,632 2,521 Selling, general and administrative 3,552 2,122 Discontinued operations (32 ) 54 Total stock-based compensation expense $ 7,835 $ 5,013 The amount of stock-based compensation expense that was capitalized during the periods presented above was not material. Stock Options The following is a summary of the Company's stock option activity and related weighted average exercise prices for each category: Three Months Ended June 28, 2015 (shares in thousands) Shares Price Beginning stock options outstanding 3,680 $ 7.71 Granted 420 21.85 Exercised (1) (467 ) 7.19 Canceled (33 ) 7.45 Ending stock options outstanding 3,600 $ 9.44 Ending stock options exercisable 2,177 $ 7.12 (1) Upon exercise, the Company issues new shares of common stock. As of June 28, 2015 , the unrecognized compensation cost related to nonvested stock options, net of estimated forfeitures, was $3.0 million and will be recognized over a weighted-average period of 1.33 years. As of June 28, 2015 , stock options vested and expected to vest totaled approximately 3.3 million with a weighted-average exercise price of $8.95 and a weighted-average remaining contractual life of 3.99 years. The aggregate intrinsic value was approximately $43.1 million . As of June 28, 2015 , fully vested stock options totaled approximately 2.2 million with a weighted-average exercise price of $7.12 and a weighted-average remaining contractual life of 3.21 years. The aggregate intrinsic value was approximately $32.2 million . Restricted Stock Units Restricted stock units granted by the Company under the 2004 Plan generally vest over at least a three year period from the grant date with one-third of restricted stock units vesting on each one-year anniversary. As of June 28, 2015 , 3.8 million restricted stock unit awards were outstanding under the 2004 Plan. The following table summarizes the Company's restricted stock unit activity and related weighted-average exercise prices for each category for the three months ended June 28, 2015 : Three Months Ended June 28, 2015 (shares in thousands) Shares Weighted-average grant date fair value per share Beginning RSUs outstanding 3,457 $ 10.58 Granted 1,381 21.96 Released (915 ) 9.13 Forfeited (159 ) 12.32 Ending RSUs outstanding 3,764 $ 15.04 As of June 28, 2015 , restricted stock units vested and expected to vest totaled approximately 3.0 million with a weighted-average remaining contract life of 1.74 years. The aggregate intrinsic value was approximately $65.5 million . As of June 28, 2015 , the unrecognized compensation cost related to restricted stock units granted under the Company’s equity incentive plan was approximately $31.9 million , net of estimated forfeitures, and is expected to be recognized over a weighted-average period of 1.88 years. Performance-Based Stock Units Under the 2004 Plan, the Company has granted performance-based stock units which vest and convert into shares of the Company's common stock based on the level of achievement of pre-established performance goals relating to Company's performance relative to a group of peer companies and to cumulative revenue targets for a specific product group, during a specified performance period. The performance period for the Company's performance-based stock units is generally 1 to 3 years. Management evaluates, on a quarterly basis, the likelihood of the Company meeting its performance metrics in determining stock-based compensation expense. The following table summarizes the Company's performance stock unit activity and related weighted-average exercise prices for each category for the three months ended June 28, 2015 : Three Months Ended June 28, 2015 (shares in thousands) Shares Weighted-average grant date fair value per share Beginning PSUs outstanding 517 $ 8.06 Granted 3 8.50 Released (89 ) 7.77 Forfeited (137 ) 8.55 Ending PSUs outstanding 294 $ 7.92 As of June 28, 2015 , performance stock units vested and expected to vest totaled approximately 0.2 million with a weighted-average remaining contract life of 0.87 year. The aggregate intrinsic value was approximately $4.9 million . As of June 28, 2015 , the unrecognized compensation cost related to performance stock units granted under the Company’s equity incentive plan was approximately $0.3 million , net of estimated forfeitures, and is expected to be recognized over a weighted-average period of 0.88 year. Market-Based Stock Units In June 2015, under the 2004 Plan, the Company granted approximately 0.2 million shares of restricted stock units with a market-based condition to a group of executive-level employees. These equity awards vest and convert into shares of the Company’s common stock based on the achievement of the Company’s relative total shareholder return over the performance period of 2 years. The earned market-based stock units will vest in two equal installments, with the first installment of vesting to occur on June 15, 2017, and the second on June 15, 2018. In June 2014, under the 2004 Plan, the Company granted approximately 0.5 million shares of restricted stock units with a market-based condition to a group of executive-level employees. These equity awards vest and convert into shares of the Company’s common stock based on the achievement of the Company’s relative total shareholder return over the performance period of 2 years. The earned market-based stock units will vest in two equal installments, with the first installment of vesting to occur on June 15, 2016, and the second on June 15, 2017. The fair value of each market-based stock unit award was estimated on the date of grant using a Monte Carlo simulation model that uses the assumptions noted in the table below. The Company uses historical data to estimate employee termination within the valuation model. The expected term of 1.80 years was derived from the output of the valuation model and represents the period of time that restricted stock units granted are expected to be outstanding. The following weighted average assumptions were used to calculate the fair value of the market-based equity award using a Monte Carlo simulation model: June 15, 2015 June 15, 2014 Estimated fair value $ 33.08 $ 21.00 Expected volatility 41.22 % 34.60 % Expected term (in years) 1.80 1.80 Risk-free interest rate 0.65 % 0.38 % Dividend yield — % — % As of June 28, 2015 , the total market-based stock units outstanding were approximately 0.8 million . As of June 28, 2015 , market-based stock units vested and expected to vest totaled approximately 0.6 million with a weighted-average remaining contract life of 1.70 years. The aggregate intrinsic value was approximately $13.6 million . As of June 28, 2015 , the unrecognized compensation cost related to market-based stock units granted under the Company’s equity incentive plans was approximately $10.9 million , net of estimated forfeitures, and is expected to be recognized over a weighted-average period of 1.76 years. 2009 Employee Stock Purchase Plan (2009 ESPP) On June 18, 2009, the Board approved implementation of the 2009 Employee Stock Purchase Plan (2009 ESPP) and authorized the reservation and issuance of up to 9.0 million shares of the Company's common stock, subject to stockholder approval. On September 17, 2009, the Company's stockholders approved the plan at the 2009 Annual Meeting of Stockholders. The 2009 ESPP is intended to be implemented in successive quarterly purchase periods commencing on the first day of each fiscal quarter of the Company. In order to maintain its qualified status under Section 423 of the Internal Revenue Code, the 2009 ESPP imposes certain restrictions, including the limitation that no employee is permitted to participate in the 2009 ESPP if the rights of such employee to purchase common stock of the Company under the 2009 ESPP and all similar purchase plans of the Company or its subsidiaries would accrue at a rate which exceeds $25,000 of the fair market value of such stock (determined at the time the right is granted) for each calendar year. At the 2012 annual meeting of stockholders on September 13, 2012, the Company's stockholders approved an additional 5.0 million . The number of shares of common stock reserved for issuance thereunder increased from 9.0 million shares to 14.0 million shares. Activity under the Company's ESPP for the three months ended June 28, 2015 is summarized in the following table: (in thousands, except per share amounts) Number of shares issued 230 Average issuance price $ 16.82 Number of shares available at June 28, 2015 4,148

Deferred Revenue Disclosure [Abstract]
Deferred Income on Shipments to Distributors	Deferred Income on Shipments to Distributors Included in the caption “Deferred income on shipments to distributors” on the Consolidated Condensed Balance Sheets are amounts related to shipments to certain distributors for which revenue is not recognized until the Company's product has been sold by the distributor to an end customer . The components of deferred income on shipments to distributors as of June 28, 2015 and March 29, 2015 are as follows: (in thousands) June 28, March 29, Gross deferred revenue $ 13,429 $ 19,299 Gross deferred costs (3,049 ) (3,605 ) Deferred income on shipments to distributors $ 10,380 $ 15,694 The gross deferred revenue represents the gross value of shipments to distributors at the list price billed to the distributor less any price protection credits provided to them in connection with reductions in list price while the products remain in their inventory. The amount ultimately recognized as revenue will be lower than this amount as a result of ship from stock pricing credits which are issued in connection with the sell through of the Company's products to end customers. Historically, this amount represents on average approximately 38% of the list price billed to the customer. The gross deferred costs represent the standard costs (which approximate actual costs) of products the Company sells to the distributors. Although the Company monitors the levels and quality of inventory in the distribution channel, the Company's experience is that products returned from these distributors may be sold to a different distributor or in a different region of the world. As such, inventory write-downs for products in the distribution channel have not been significant.

The Plan sets forth the general parameters, terms and benefits for employee dismissals. The Plan was approved by the French Works Council and Labor Administrator and the related Plan details were communicated to the affected employees in France and the Netherlands. No works council consultation was required in the Netherlands. The Company has not historically offered similar termination benefits as defined in the Plan for these locations. The Plan identified the number of employees to be terminated, their job classification or function, their location and the date that the Plan was expected to be completed. The Plan also established the terms of the benefit arrangement in sufficient detail to enable the employees to determine the type and amount of benefits that they would receive if terminated. In addition, the actions required to complete the Plan indicated that it was unlikely that substantial changes to the Plan would be made after communication to the employees. Accordingly, the Company accrued restructuring charges in accordance with ASC 420, Exit or Disposal Cost Obligations . The restructuring charges recorded to discontinued operations in the Condensed Consolidated Statement of Operations were approximately $18.3 million for the fiscal year ended March 29, 2015 , for a total of 53 employees in France and the Netherlands combined. The Company expects payments to these termination benefits and to complete the restructuring action by December 2017. Other During the first quarter of fiscal 2016, the Company recorded other restructuring charges of $0.9 million and reduced headcount by 11 employees. As of June 28, 2015 , the total accrued balance for employee severance costs related to these restructuring actions was $0.5 million . The Company expects to complete these restructuring actions during the second quarter of fiscal 2016. During fiscal 2015, the Company recorded other restructuring charges of $1.1 million and reduced headcount by 28 employees in multiple reductions in workforce actions. During fiscal 2015, the Company paid $0.8 million related to these actions. During first quarter of fiscal 2016, the Company paid $0.3 million related to these actions. As of June 28, 2015 , the total accrued balance for employee severance costs related to these restructuring actions was zero .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Warranty The Company maintains an accrual for obligations it incurs under its standard product warranty program and customer, part, or process specific matters. The Company’s standard warranty period is one year, however in certain instances the warranty period may be extended to as long as two years. Management estimates the fair value of the Company’s warranty liability based on actual past warranty claims experience, its policies regarding customer warranty returns and other estimates about the timing and disposition of product returned under the standard program. Customer, part, or process specific accruals are estimated using a specific identification method. Historical profit and loss impact related to warranty returns activity has been minimal. The total warranty accrual was $0.1 million as of June 28, 2015 and March 29, 2015 . Litigation In January 2012, Maxim I Properties, a general partnership that had purchased a certain parcel of real property (the Property) in 2003, filed a complaint in the Northern District of California naming approximately 30 defendants, including the Company ("Defendants"), alleging various environmental violations of the federal Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and Resource Conservation and Recovery Act (RCRA), the California Hazardous Substance Account Act (HSAA), and other common law claims (the Complaint). The Complaint alleges that Defendants including the Company “…generated, transported, and/or arranged for the transport and/or disposal of hazardous waste to the Property.” The Complaint further alleges that Defendants are liable for the costs of investigation and remediation of the Property due to the release of hazardous substances, and that Defendants violated their duty to prevent the release of such hazardous substances. On August 15, 2012, the plaintiff voluntarily dismissed its Complaint against the Company without prejudice. However, Moyer Products, Inc., another defendant, counter-claimed against the plaintiff Maxim and cross-claimed against Defendants, including the Company, and thus the Company remains a cross-defendant in this action. In September 2012, the California Department of Toxic Substances Control (DTSC) notified the Company that it identified the Company, along with more than 50 other entities, as a respondent to DTSC's Enforcement Order, as “a generator of hazardous waste” that was sent to the Property. In April 2013, the Company, along with the other “respondent” parties, entered into a Corrective Action Consent Agreement (CACA) to conduct the Property investigation and corrective action selection. The CACA supersedes the Enforcement Order. In February 2013, the court stayed the Maxim/Moyer litigation pending the Property investigation under the CACA and DTSC's corrective action selection. On June 23, 2015, the Property investigation was deemed completed by DTSC. The DTSC continues to evaluate corrective action. The Company will continue to vigorously defend itself against the allegations in the Complaint and evaluate settlement options with Moyer upon notification from the DTSC of its corrective action selection. Because no specific corrective action has been selected yet, and thus no specific monetary demands have been made, it is not possible for the Company to estimate the potential loss or range of potential losses for these actions. The Company is also party to various other legal proceedings and claims arising in the normal course of business. As of June 28, 2015 , while the Company has accrued for specific amounts based on the probability of settlement in some of these matters, those amounts, both individually and in total, are not material to any aspect of business operations and to the consolidated financial statements. Further, with regard to these other matters, potential liability and probable losses or ranges of possible losses cannot be reasonably estimated at this time. Generally, litigation is subject to inherent uncertainties, and no assurance can be given that the Company will prevail in any particular lawsuit. Accordingly, pending lawsuits, as well as potential future litigation with other companies, could result in substantial costs and diversion of resources and could have a material adverse effect on the Company's financial condition, results of operations or cash flows.

Compensation and Retirement Disclosure [Abstract]
Employee Benefit Plans	Employee Benefit Plans 401(k) Plan The Company sponsors a 401(k) retirement matching plan for qualified domestic employees. The Company recorded expenses of approximately $ 1.0 million and $ 0.7 million in matching contributions under the plan during the three months ended June 28, 2015 and June 29, 2014 , respectively. Deferred Compensation Plans Effective November 1, 2000, the Company established an unfunded deferred compensation plan to provide benefits to executive officers and other key employees. Under the plan, participants can defer any portion of their salary and bonus compensation into the plan and may choose from a portfolio of funds from which earnings are measured. Participant balances are always 100% vested. As of June 28, 2015 and March 29, 2015 , obligations under the plan totaled approximately $14.9 million and $13.1 million . Additionally, the Company has set aside assets in a separate trust that is invested in corporate owned life insurance intended to substantially fund the liability under the plan. As of June 28, 2015 and March 29, 2015 , the deferred compensation plan assets were approximately $15.1 million and $16.5 million respectively. During the first quarter of fiscal 2013, the Company assumed a deferred compensation plan associated with the acquisition of Fox. Under this plan, participants in retirement are entitled to receive a fixed amount from the Company on a monthly basis. The Company has purchased life insurance policies with the intention of funding the liability under this plan. As of June 28, 2015 and March 29, 2015 , the deferred compensation plan assets under this plan were approximately $0.8 million . As of June 28, 2015 and March 29, 2015 , the deferred compensation plan liabilities under this plan were approximately $ 1.8 million and $1.7 million , respectively. International Employee Benefit Plans The Company sponsors defined-benefit pension plans, defined-contribution plans, multi-employer plans and other post-employment benefit plans covering employees in certain of the Company's international locations. As of June 28, 2015 and March 29, 2015, the net liability for all of these international benefit plans totaled $ 0.9 million and $1.0 million respectively.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes During the three months ended June 28, 2015 and June 29, 2014 , the Company recorded an income tax expense from continuing operations of $0.4 million and $0.3 million , respectively. The income tax expense recorded during the three months ended June 28, 2015 was primarily due to taxes on earnings in foreign jurisdictions. The income tax expense recorded during the three months ended June 29, 2014 was primarily due to U.S. federal and state tax on U.S. earnings. As of June 28, 2015, the Company continued to maintain a valuation allowance against its net U.S. and foreign deferred tax assets, as the Company could not conclude that it was more likely than not that the Company would be able to realize its U.S. and foreign deferred tax assets. Given the continued improvement in the Company’s operations combined with certain tax strategies, it is reasonably possible that within the next 12 months, positive evidence will be sufficient to release a material amount of the Company’s valuation allowance. Release of the valuation allowance would result in the recognition of certain deferred tax assets and a decrease to income tax expense for the period the release is recorded. The exact timing and amount of the valuation allowance release are subject to change on the basis of the level of profitability that the Company is able to actually achieve. The Company will continue to evaluate the release of the valuation allowance on a quarterly basis. After examination of the Company’s projected offshore cash flows, and global cash requirements, the Company determined that beginning in fiscal year 2016, the Company would no longer require 100% of its foreign generated cash to support its foreign operations. The Company plans to repatriate a portion of its current year offshore earnings to the U.S. for domestic operations. For earnings accumulated as of March 29, 2015, the Company continues to permanently reinvest such amounts in its foreign jurisdictions, except to the extent there is any previously taxed income which is expected to be repatriated. If circumstances change and it becomes apparent that some or all of those undistributed earnings of the Company's offshore subsidiary will be remitted in the foreseeable future but income taxes have not been recognized, the Company will accrue income taxes attributable to that remittance. The Company benefits from tax incentives granted by local tax authorities in certain foreign jurisdictions. In the fourth quarter of fiscal 2011, the Company agreed with the Malaysia Industrial Development Board to enter into a new tax incentive agreement which is a full tax exemption on statutory income for a period of 10 years commencing April 4, 2011. This tax incentive agreement is subject to the Company meeting certain financial targets, investments, headcounts and activities in Malaysia. During the quarter ended June 28, 2015, the Company reached an understanding regarding the terms for settling with the U.S. Internal Revenue Service ("IRS") and closed out all positions as part of the examination of the Company's income tax returns for the fiscal years 2010 through 2012. As a result, the Company remeasured its tax positions based on the facts, circumstances, and information available at the reporting date. The outcome did not have a material effect on the Company’s financial position, cash flows or results of operations due to its tax attributes, which are fully offset by a valuation allowance. As of June 28, 2015, the Company was under examination in Singapore. The Company's fiscal years 2009 through 2012 are under audit by the Inland Revenue Authority of Singapore. Although the final outcome is uncertain, based on currently available information, the Company believes that the ultimate outcome will not have a material adverse effect on its financial position, cash flows or results of operations. The Company's open years in the U.S. federal jurisdiction are fiscal 2013 and later years. In addition, the Company is effectively subject to federal tax examination adjustments for tax years ended on or after fiscal year 1999, in that the Company has tax attribute carryforwards from these years that could be subject to adjustments, if and when utilized. The Company's open years in various state and foreign jurisdictions are fiscal years 2008 and later. The Company does not expect a material change in unrecognized tax benefits within the next twelve months.

Summary of Significant Accounting Policies (Policies)	Jun. 28, 2015
Accounting Policies [Abstract]
Basis of Presentation.	Basis of Presentation . The Company's fiscal year is the 52 or 53 week period ending on the Sunday closest to March 31. In a 52 week year, each fiscal quarter consists of 13 weeks. In a 53 week year, the additional week is usually added to the third quarter, making such quarter consist of 14 weeks. The first quarters of fiscal 2016 and fiscal 2015 were 13 week periods.
Principles of Consolidation.	Principles of Consolidation . The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All inter-company accounts and transactions have been eliminated.
Use of Estimates.	Use of Estimates . The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.
Recent Accounting Pronouncements.	Recent Accounting Pronouncements Accounting Pronouncements Not Yet Effective for Fiscal 2016 In July 2015, the Financial Accounting Standards Board (FASB) issued guidance applying to inventory measured using any other method other than last-in, last-out method. Under this guidance, inventory is measured at the lower of cost and net realizable value. The net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The guidance is applied prospectively and is effective for the Company in its first quarter of fiscal 2018. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on the Company’s financial statements and related disclosures. In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements - Going Concern, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. This standard sets forth management’s responsibility to evaluate, each reporting period, whether there is substantial doubt about an entity’s ability to continue as a going concern, and if so, to provide related footnote disclosures. The standard is effective for annual reporting periods ending after December 15, 2016 and interim periods within annual periods beginning after December 15, 2016. The Company does not believe that the adoption of this guidance will have any material impact on its financial position or results of operations. On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The standard permits the use of either the retrospective or cumulative effect transition method. On July 9, 2015, the FASB decided to delay the effective date by one year to December 15, 2017 for annual periods beginning after that date. The FASB also decided to allow early adoption of the standard, but not before the original effective date of December 15, 2016. The Company is currently evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.
