Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of PresentationThe consolidated condensed financial statements have been prepared by Cirrus Logic, Inc. (“Cirrus Logic,” “we,” “us,” “our,” or the “Company”) pursuant to the rules and regulations of the Securities and Exchange Commission (the “Commission”).  The accompanying unaudited consolidated condensed financial statements do not include complete footnotes and financial presentations.  As a result, these financial statements should be read along with the audited consolidated financial statements and notes thereto for the year ended March 30, 2019, included in our Annual Report on Form 10-K filed with the Commission on May 24, 2019.  In our opinion, the financial statements reflect all material adjustments, including normal recurring adjustments, necessary for a fair presentation of the financial position, operating results and cash flows for those periods presented.  The preparation of financial statements in conformity with United States (“U.S.”) generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect reported assets, liabilities, revenues and expenses.  Actual results could differ from those estimates and assumptions.  Moreover, the results of operations for the interim periods presented are not necessarily indicative of the results that may be expected for the entire year. Additionally, certain prior period amounts have been reclassified to conform to current year presentation, with no impact to earnings.

Accounting Changes and Error Corrections [Abstract]
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-02, Leases , which the Company adopted in the first quarter of fiscal year 2020. The new standard provides a number of optional practical expedients in transition. We elected the use-of-hindsight practical expedient and the ‘package of practical expedients’ which permit us not to reassess our prior conclusions about lease identification, lease classification and initial direct costs. The new standard also provides practical expedients for an entity’s ongoing accounting. We elected the short-term lease recognition exemption for all leases that qualify. This means, for qualifying leases, which are those with initial terms of less than twelve months, we will not recognize right-of-use ("ROU") assets or lease liabilities. We also do not separate lease and non-lease components for all classes of assets. Most of our operating lease commitments were subject to the new standard and recognized as ROU assets and operating lease liabilities upon adoption, which materially increased the total assets and total liabilities that we reported relative to such amounts prior to adoption. In applying the use-of-hindsight practical expedient, we re-assessed whether we were reasonably certain to exercise extension options within our lease agreements. This resulted in the lease term being extended on a number of leases. The previously capitalized initial direct costs and accrued lease payments were recalculated assuming these extended lease terms had always applied, resulting in an adjustment of $0.7 million net of tax, to opening retained earnings on transition. On adoption, we recognized additional operating liabilities, with corresponding ROU assets based on the present value of the lease payments over the lease term under current leasing contracts for existing operating leases. In addition, existing capitalized initial direct costs and accrued lease payments were reclassified from prepayments and accruals to the ROU asset. There was no income statement or material cash flow statement impact on adoption, nor were prior periods adjusted. The effects of the changes made to our balance sheet at adoption were as follows (in thousands): Balance at March 30, 2019 Impact from ASU 2016-02 Adoption Balance at March 31, 2019 Financial statement line item: Prepaid assets $ 30,794 $ (2,833) $ 27,961 Right-of-use lease assets — 149,746 149,746 Lease liabilities — (14,899) (14,899) Other accrued liabilities (16,339) 11,071 (5,268) Non-current lease liabilities — (143,085) (143,085) Other long-term liabilities (9,889) (965) (10,854) Accumulated deficit (222,430) 965 (221,465) In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . This ASU requires credit losses on available-for-sale debt securities to be presented as an allowance rather than a write-down. Unlike current U.S. GAAP, the credit losses could be reversed with changes in estimates, and recognized in current year earnings. This ASU is effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods. Early adoption is permitted for annual periods beginning after December 15, 2018, including interim periods. The Company is currently evaluating the impact of this ASU, but does not expect a material impact to the financial statements upon adoption. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . This ASU eliminates step two of the goodwill impairment test. An impairment charge is to be recognized for the amount by which the current value exceeds the fair value. This ASU is effective for annual periods beginning after December 15, 2019, including interim periods. Early adoption is permitted, for interim or annual goodwill impairment tests performed after January 1, 2017, and should be applied prospectively. An entity is required to disclose the nature of and reason for the change in accounting principle upon transition. That disclosure should be provided in the first annual period and in the interim period within the first annual period when the entity initially adopts the amendments in this update. The Company is currently evaluating the impact of this ASU, but does not expect a material impact to the financial statements upon adoption. In February 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income . This ASU allows for the classification of stranded tax effects resulting from the Tax Cuts and Jobs Act (the “Tax Act”) from accumulated other comprehensive income to retained earnings. This ASU is effective for annual periods beginning after December 15, 2018, with early adoption permitted. The standard should be applied in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in tax rate is recognized. The Company adopted this ASU in the first quarter of fiscal year 2020 and elected to reclassify the stranded tax effects of $0.3 million from accumulated other comprehensive income to retained earnings in the period of adoption. In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting . This ASU expands the scope of Topic 718 to include all share-based payment transactions for acquiring goods and services from nonemployees and will apply to all share-based payment transactions in which the grantor acquires goods and services to be used or consumed in its own operations by issuing share-based payment awards. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year, with early adoption permitted. The Company adopted this ASU in the first quarter of fiscal year 2020, with no material impact to the financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement . This ASU adjusts current required disclosures related to fair value measurements. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within that fiscal year, with early adoption permitted. The Company is currently evaluating the impact of this ASU, but does not expect a material impact to the financial statements upon adoption. In August 2018, the Commission adopted the final rule under SEC Release No. 33-10532, Disclosure Update and Simplification

Marketable Securities [Abstract]
Marketable Securities	Marketable SecuritiesThe Company’s investments that have original maturities greater than 90 days have been classified as available-for-sale securities in accordance with U.S. GAAP. Marketable securities are categorized on the consolidated condensed balance sheet as short- and long-term marketable securities, as appropriate. The following table is a summary of available-for-sale securities at September 28, 2019 (in thousands): As of September 28, 2019 Amortized Gross Gross Estimated Corporate debt securities $ 234,115 $ 2,810 $ (30) $ 236,895 Non-U.S. government securities 14,404 111 (7) 14,508 U.S. Treasury securities 9,891 32 (22) 9,901 Total securities $ 258,410 $ 2,953 $ (59) $ 261,304 The Company typically invests in highly-rated securities with original maturities generally ranging from one to securities with total amortized cost of approximately $28.2 million at September 28, 2019. Securities in a continuous unrealized loss position for more than 12 months as of September 28, 2019 had an aggregate amortized cost of $5.5 million and an immaterial amount of aggregate unrealized loss. The Company may sell certain of its marketable securities prior to their stated maturities for strategic reasons including, but not limited to, anticipated or actual changes in credit rating and duration management. When evaluating an investment for other-than-temporary impairment, the Company reviews factors including the length of time and extent to which fair value has been below cost basis, the financial condition of the issuer, changes in market interest rates and whether it is more likely than not the Company will be required to sell the investment before recovery of the investment’s cost basis. As of September 28, 2019, the Company did not consider any of its investments to be other-than-temporarily impaired.

Fair Value of Financial Instruments	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company has determined that the only material assets and liabilities in the Company’s financial statements that are required to be measured at fair value on a recurring basis are the Company’s cash equivalents and marketable securities portfolio. The Company defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). • Level 1 - Quoted prices in active markets for identical assets or liabilities. • Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company’s cash equivalents and marketable securities portfolio consist of money market funds, debt securities, non-U.S. government securities, U.S. Treasury securities and securities of U.S. government-sponsored enterprises and are reflected on our consolidated condensed balance sheets under the headings cash and cash equivalents, marketable securities, and long-term marketable securities. The Company determines the fair value of its marketable securities portfolio by obtaining non-binding market prices from third-party pricing providers on the last day of the quarter, whose sources may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value. As of September 28, 2019 and March 30, 2019, the Company classified all investment portfolio assets as Level 1 or Level 2 assets. The Company has no material Level 3 assets. There were no transfers between Level 1, Level 2, or Level 3 measurements for the three months ending September 28, 2019. The following summarizes the fair value of our financial instruments at September 28, 2019 (in thousands):  Quoted Prices Significant Significant Total Assets: Cash equivalents Money market funds $ 186,669 $ — $ — $ 186,669 Available-for-sale securities Corporate debt securities $ — $ 236,895 $ — $ 236,895 Non-U.S. government securities — 14,508 — 14,508 U.S. Treasury securities 9,901 — — 9,901  $ 9,901 $ 251,403 $ — $ 261,304 ໿ The following summarizes the fair value of our financial instruments at March 30, 2019 (in thousands):  Quoted Prices Significant Significant Total Assets: Cash equivalents Money market funds $ 174,214 $ — $ — $ 174,214 Available-for-sale securities Corporate debt securities $ — $ 215,525 $ — $ 215,525 Non-U.S. government securities — 13,177 — 13,177 Agency discount notes — 449 — 449 $ — $ 229,151 $ — $ 229,151 ໿

Derivative Financial Instruments	Derivative Financial Instruments Foreign Currency Forward Contracts Beginning in the first quarter of fiscal year 2020, the Company began using foreign currency forward contracts to reduce the earnings impact that exchange rate fluctuations have on non-U.S. dollar balance sheet exposures. The Company recognizes both the gains and losses on foreign currency forward contracts and the gains and losses on the remeasurement of non-U.S. dollar denominated assets and liabilities within " Other expense " in the consolidated condensed statements of income. The Company does not apply hedge accounting to these foreign currency derivative instruments. As of September 28, 2019, the Company held one foreign currency forward contract denominated in British Pound Sterling with a notional value of $57.0 million. The fair value of this contract was not material as of September 28, 2019.

Line of Credit Facility [Abstract]
Revolving Credit Facility	Revolving Credit Facility On July 12, 2016, Cirrus Logic entered into an amended and restated credit agreement (the “Credit Agreement”) with Wells Fargo Bank, National Association, as Administrative Agent, and the Lenders party thereto, for the purpose of refinancing an existing credit facility and providing ongoing working capital. The Credit Agreement provides for a $300 million senior secured revolving credit facility (the “Credit Facility”). The Credit Facility matures on July 12, 2021. The Credit Facility is required to be guaranteed by all of Cirrus Logic’s material domestic subsidiaries (the “Subsidiary Guarantors”). The Credit Facility is secured by substantially all of the assets of Cirrus Logic and any Subsidiary Guarantors, except for certain excluded assets. Borrowings under the Credit Facility may, at our election, bear interest at either (a) a base rate plus the applicable margin (“Base Rate Loans”) or (b) a LIBOR rate plus the applicable margin (“LIBOR Rate Loans”). The applicable margin ranges from 0% to 0.50% per annum for Base Rate Loans and 1.25% to 2.00% per annum for LIBOR Rate Loans based on the Leverage Ratio (as defined below). A commitment fee accrues at a rate per annum ranging from 0.20% to 0.30% (based on the Leverage Ratio) on the average daily unused portion of the commitment of the lenders. The Credit Agreement contains certain financial covenants providing that (a) the ratio of consolidated funded indebtedness to consolidated EBITDA for the prior four fiscal quarters must not be greater than 3.00 to 1.00 (the “Leverage Ratio”) and (b) the ratio of consolidated EBITDA for the prior four consecutive fiscal quarters to consolidated fixed charges (including amounts paid in cash for consolidated interest expenses, capital expenditures, scheduled principal payments of indebtedness, and income taxes) for the prior four consecutive fiscal quarters must not be less than 1.25 to 1.00 as of the end of each fiscal quarter. The Credit Agreement also contains negative covenants limiting the Company’s or any Subsidiary’s ability to, among other things, incur debt, grant liens, make investments, effect certain fundamental changes, make certain asset dispositions, and make certain restricted payments.

Leases

Leases [Abstract]
Leases	Leases The Company has operating leases for corporate offices and certain office equipment. Our leases have remaining lease terms of 1 year to 28 years, some of which include options to extend the leases that are considered reasonably certain to be exercised. Our leases generally contain fixed rental payments, with additional variable payments linked to actual common area maintenance costs incurred by the landlord. These variable payments are therefore not included within the lease liability and ROU asset, but are recognized as an expense when incurred. As our leases typically do not provide an implicit rate, the Company determined the Incremental Borrowing Rate ("IBR") for each lease based on the information available at the commencement date, taking into consideration necessary adjustments for collateral, currency, and lease term. There are no residual value guarantees in any of our leases. No restrictions or covenants have been imposed on the Company as a result of the lease agreements in place. The Company also leases a small portion of our office space to tenants under operating leases, receiving monthly rental payments. Payments are generally fixed, with variable payments linked to actual common area maintenance costs incurred. Total fixed lease payments to be received over the life of the lease are recognized on a straight-line basis over the lease term. All of the Company’s leases have been classified as operating leases. Operating leases in excess of 12 months are recognized on the balance sheet, with future lease payments recognized as a liability, measured at present value, and the right-of-use asset recognized for the lease term. A single lease cost is recognized in the income statement over the lease term.

Revenue from Contract with Customer [Abstract]
Revenues	Revenues Disaggregation of revenue We disaggregate revenue from contracts with customers based on the ship to location of the customer. The geographic regions that are reviewed are the United States and countries outside of the United States (primarily located in Asia). Total net sales based on the disaggregation criteria described above are as follows: Three Months Ended Six Months Ended September 28, September 29, September 28, September 29, 2019 2018 2019 2018 Non-United States $ 385,222 $ 359,685 $ 619,263 $ 605,307 United States 3,690 6,620 7,902 15,481 $ 388,912 $ 366,305 $ 627,165 $ 620,788 Performance obligations The Company's single performance obligation is the delivery of promised goods to the customer. The promised goods are explicitly stated in the customer contract and are comprised of either a single type of good or a series of goods that are substantially the same, have the same pattern of transfer to the customer, and are neither capable of being distinct nor separable from the other promised goods in the contract. This performance obligation is satisfied upon transfer of control of the promised goods to the customer, as defined per the shipping terms within the customer's contract. The vast majority of the Company's contracts with customers have an original expected term length of one year or less. As allowed by ASC 606, the Company has not disclosed the value of any unsatisfied performance obligations related to these contracts. The Company’s products primarily include a warranty period of one Guarantees , and are not considered a separate performance obligation. Contract balances Payments are typically due within 30 to 60 days of invoicing and terms do not include a significant financing components or noncash consideration. There have been no material impairment losses on accounts receivable. There are no material contract assets or contract liabilities recorded on the consolidated condensed balance sheets. Transaction price The transaction price is the amount of consideration to which the Company expects to be entitled in exchange for transferring the promised goods to the customer. Fixed pricing is the consideration that is agreed upon in the customer contract. Variable pricing includes rebates, rights of return, warranties, price protection and stock rotation. Rebates are granted as a customer account credit, based on agreed-upon sales thresholds. Rights of return and warranty costs are estimated using the "most likely amount" method by reviewing historical returns to determine the most likely customer return rate and applying materiality thresholds. Price protection includes price adjustments available to certain distributors based upon established book price and a stated adjustment period. Stock rotation is also available to certain distributors based on a stated maximum of prior billings. The Company estimates all variable consideration at the most likely amount that it expects to be entitled. The estimate is based on current and historical information, including recent sales activity and pricing, available to the Company. Variable consideration is only included in the transaction price to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The Company defers all variable consideration that does not meet the revenue recognition criteria.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes ໿ Our provision (benefit) for income taxes is based on estimated effective tax rates derived from an estimate of annual consolidated earnings before taxes, adjusted for nondeductible expenses, other permanent items and any applicable credits. The following table presents the provision (benefit) for income taxes (in thousands) and the effective tax rates:  Three Months Ended Six Months Ended  September 28, September 29, September 28, September 29,  2019 2018 2019 2018 Income before income taxes $ 88,358 $ 56,725 $ 94,409 $ 52,225 Provision (benefit) for income taxes $ 12,148 $ (1,448) $ 13,581 $ (1,676) Effective tax rate 13.7 % (2.6) % 14.4 % (3.2) % Our income tax expense for the second quarter of fiscal year 2020 was $12.1 million compared to $1.4 million of income tax benefit for the second quarter of fiscal year 2019, resulting in effective tax rates of 13.7% and (2.6)% for the second quarter of fiscal year 2020 and 2019, respectively. Our income tax expense was $13.6 million for the first six months of fiscal year 2020 compared to income tax benefit of $1.7 million for the first six months of fiscal year 2019, resulting in effective tax rates of 14.4% and (3.2)%, respectively. Our effective tax rates for the second quarter and first six months of fiscal year 2020 were lower than the federal statutory rate primarily due to the effect of income earned in certain foreign jurisdictions that is taxed below the federal statutory rate, the U.S. deduction for foreign derived intangible income, and the release of prior year unrecognized tax benefits due to the closure of the tax audit of the Company's U.K. subsidiaries in the second quarter of fiscal year 2020. Our effective tax rates for the second quarter and first six months of fiscal year 2019 were lower than the federal statutory rate primarily due to adjustments recorded in the second quarter of fiscal year 2019 to reduce the provisional amount of the Tax Act's transition tax, the effect of income earned in certain foreign jurisdictions that is taxed below the federal statutory rate, and the U.S. federal research and development tax credit. The Company records unrecognized tax benefits for the estimated risk associated with tax positions taken on tax returns. At September 28, 2019, the Company had unrecognized tax benefits of $39.0 million, of which $38.8 million would impact the effective tax rate if recognized. We recorded gross increases of $0.3 million and $0.1 million to current year unrecognized tax benefits in the first and second quarters of fiscal year 2020, respectively, as well as a gross decrease of $1.1 million to prior year unrecognized tax benefits in the second quarter of fiscal year 2020. The Company believes it is reasonably possible that the gross unrecognized tax benefits could decrease by approximately $3.0 million in the next 12 months due to the lapse of the statute of limitations applicable to tax positions taken on a prior year tax return. The Company’s total unrecognized tax benefits are classified as “ Non-current income taxes" in the consolidated condensed balance sheets. The Company recognizes interest and penalties related to unrecognized tax benefits in the provision for income taxes. As of September 28, 2019, the balance of accrued interest and penalties, net of tax, was $3.4 million. On July 27, 2015, the U.S. Tax Court issued an opinion in Altera Corp. et al. v. Commissioner which concluded that the regulations relating to the treatment of stock-based compensation expense in intercompany cost-sharing arrangements were invalid. In 2016 the U.S. Internal Revenue Service appealed the decision to the U.S. Court of Appeals for the Ninth Circuit (the “Ninth Circuit”). On July 24, 2018, the Ninth Circuit issued a decision that was subsequently withdrawn and a reconstituted panel has conferred on the appeal. On June 7, 2019, the Ninth Circuit reversed the decision of the U.S. Tax Court and upheld the cost-sharing regulations. The final resolution with respect to cost-sharing of stock-based compensation and the potential impact on the Company is unclear at this time. We will continue to monitor developments related to this decision and the potential impact of those developments on the Company's current and prior fiscal years. The Company and its subsidiaries are subject to U.S. federal income tax as well as income tax in multiple state and foreign jurisdictions. Fiscal years 2016 through 2019 remain open to examination by the major taxing jurisdictions to which the Company is subject, although carry forward attributes that were generated in tax years prior to fiscal year 2016 may be adjusted upon examination by the tax authorities if they have been, or will be, used in a future period. The Company's federal income tax returns for fiscal years 2017 and 2018 are under examination by the U.S. Internal Revenue Service. The Company believes it has accrued adequate reserves related to the matters under examination. The Company is not under an income tax audit in any other major taxing jurisdiction.

Earnings Per Share [Abstract]
Net Income Per Share	Net Income Per Share Basic net income per share is based on the weighted effect of common shares issued and outstanding and is calculated by dividing net income by the basic weighted average shares outstanding during the period. Diluted net income per share is calculated by dividing net income by the weighted average number of common shares used in the basic net income per share calculation, plus the equivalent number of common shares that would be issued assuming exercise or conversion of all potentially dilutive common shares outstanding. These potentially dilutive items consist primarily of outstanding stock options and restricted stock units.

Commitments and Contingencies Disclosure [Abstract]
Legal Matters	Legal Matters From time to time, we are involved in legal proceedings concerning matters arising in connection with the conduct of our business activities. We regularly evaluate the status of legal proceedings in which we are involved in order to assess whether a loss is probable or there is a reasonable possibility that a loss or additional loss may have been incurred, and to determine if accruals are appropriate. We further evaluate each legal proceeding to assess whether an estimate of possible loss or range of loss can be made. Based on current knowledge, management does not believe that there are any pending matters that could potentially have a material adverse effect on our business, financial condition, results of operations or cash flows. However, we are engaged in various legal actions in the normal course of business. There can be no assurances in light of the inherent uncertainties involved in any potential legal proceedings, some of which are beyond our control, and an adverse outcome in any legal proceeding could be material to our results of operations or cash flows for any particular reporting period.

Our Chief Executive Officer (“CEO”) has been identified as the chief operating decision maker under these guidelines. The Company operates and tracks its results in one reportable segment, but reports revenue in two product lines, Portable and Non-Portable and Other. Our CEO receives and uses enterprise-wide financial information to assess financial performance and allocate resources, rather than detailed information at a product line level. Additionally, our product lines have similar characteristics and customers. They share support functions such as sales, public relations, supply chain management, various research and development and engineering support, in addition to the general and administrative functions of human resources, legal, finance and information technology. Therefore, there is no complete, discrete financial information maintained for these product lines.

Accounting Changes and Error Corrections [Abstract]
Recently Issued Accounting Pronouncements	In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-02, Leases , which the Company adopted in the first quarter of fiscal year 2020. The new standard provides a number of optional practical expedients in transition. We elected the use-of-hindsight practical expedient and the ‘package of practical expedients’ which permit us not to reassess our prior conclusions about lease identification, lease classification and initial direct costs. The new standard also provides practical expedients for an entity’s ongoing accounting. We elected the short-term lease recognition exemption for all leases that qualify. This means, for qualifying leases, which are those with initial terms of less than twelve months, we will not recognize right-of-use ("ROU") assets or lease liabilities. We also do not separate lease and non-lease components for all classes of assets. Most of our operating lease commitments were subject to the new standard and recognized as ROU assets and operating lease liabilities upon adoption, which materially increased the total assets and total liabilities that we reported relative to such amounts prior to adoption. In applying the use-of-hindsight practical expedient, we re-assessed whether we were reasonably certain to exercise extension options within our lease agreements. This resulted in the lease term being extended on a number of leases. The previously capitalized initial direct costs and accrued lease payments were recalculated assuming these extended lease terms had always applied, resulting in an adjustment of $0.7 million net of tax, to opening retained earnings on transition. On adoption, we recognized additional operating liabilities, with corresponding ROU assets based on the present value of the lease payments over the lease term under current leasing contracts for existing operating leases. In addition, existing capitalized initial direct costs and accrued lease payments were reclassified from prepayments and accruals to the ROU asset. There was no income statement or material cash flow statement impact on adoption, nor were prior periods adjusted. The effects of the changes made to our balance sheet at adoption were as follows (in thousands): Balance at March 30, 2019 Impact from ASU 2016-02 Adoption Balance at March 31, 2019 Financial statement line item: Prepaid assets $ 30,794 $ (2,833) $ 27,961 Right-of-use lease assets — 149,746 149,746 Lease liabilities — (14,899) (14,899) Other accrued liabilities (16,339) 11,071 (5,268) Non-current lease liabilities — (143,085) (143,085) Other long-term liabilities (9,889) (965) (10,854) Accumulated deficit (222,430) 965 (221,465) In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . This ASU requires credit losses on available-for-sale debt securities to be presented as an allowance rather than a write-down. Unlike current U.S. GAAP, the credit losses could be reversed with changes in estimates, and recognized in current year earnings. This ASU is effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods. Early adoption is permitted for annual periods beginning after December 15, 2018, including interim periods. The Company is currently evaluating the impact of this ASU, but does not expect a material impact to the financial statements upon adoption. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . This ASU eliminates step two of the goodwill impairment test. An impairment charge is to be recognized for the amount by which the current value exceeds the fair value. This ASU is effective for annual periods beginning after December 15, 2019, including interim periods. Early adoption is permitted, for interim or annual goodwill impairment tests performed after January 1, 2017, and should be applied prospectively. An entity is required to disclose the nature of and reason for the change in accounting principle upon transition. That disclosure should be provided in the first annual period and in the interim period within the first annual period when the entity initially adopts the amendments in this update. The Company is currently evaluating the impact of this ASU, but does not expect a material impact to the financial statements upon adoption. In February 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income . This ASU allows for the classification of stranded tax effects resulting from the Tax Cuts and Jobs Act (the “Tax Act”) from accumulated other comprehensive income to retained earnings. This ASU is effective for annual periods beginning after December 15, 2018, with early adoption permitted. The standard should be applied in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in tax rate is recognized. The Company adopted this ASU in the first quarter of fiscal year 2020 and elected to reclassify the stranded tax effects of $0.3 million from accumulated other comprehensive income to retained earnings in the period of adoption. In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting . This ASU expands the scope of Topic 718 to include all share-based payment transactions for acquiring goods and services from nonemployees and will apply to all share-based payment transactions in which the grantor acquires goods and services to be used or consumed in its own operations by issuing share-based payment awards. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year, with early adoption permitted. The Company adopted this ASU in the first quarter of fiscal year 2020, with no material impact to the financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement . This ASU adjusts current required disclosures related to fair value measurements. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within that fiscal year, with early adoption permitted. The Company is currently evaluating the impact of this ASU, but does not expect a material impact to the financial statements upon adoption. In August 2018, the Commission adopted the final rule under SEC Release No. 33-10532, Disclosure Update and Simplification
Fair Value of Financial Instruments	The Company has determined that the only material assets and liabilities in the Company’s financial statements that are required to be measured at fair value on a recurring basis are the Company’s cash equivalents and marketable securities portfolio. The Company defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). • Level 1 - Quoted prices in active markets for identical assets or liabilities. • Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company’s cash equivalents and marketable securities portfolio consist of money market funds, debt securities, non-U.S. government securities, U.S. Treasury securities and securities of U.S. government-sponsored enterprises and are reflected on our consolidated condensed balance sheets under the headings cash and cash equivalents, marketable securities, and long-term marketable securities. The Company determines the fair value of its marketable securities portfolio by obtaining non-binding market prices from third-party pricing providers on the last day of the quarter, whose sources may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value.
Leases	The Company has operating leases for corporate offices and certain office equipment. Our leases have remaining lease terms of 1 year to 28 years, some of which include options to extend the leases that are considered reasonably certain to be exercised. Our leases generally contain fixed rental payments, with additional variable payments linked to actual common area maintenance costs incurred by the landlord. These variable payments are therefore not included within the lease liability and ROU asset, but are recognized as an expense when incurred. As our leases typically do not provide an implicit rate, the Company determined the Incremental Borrowing Rate ("IBR") for each lease based on the information available at the commencement date, taking into consideration necessary adjustments for collateral, currency, and lease term. There are no residual value guarantees in any of our leases. No restrictions or covenants have been imposed on the Company as a result of the lease agreements in place. The Company also leases a small portion of our office space to tenants under operating leases, receiving monthly rental payments. Payments are generally fixed, with variable payments linked to actual common area maintenance costs incurred. Total fixed lease payments to be received over the life of the lease are recognized on a straight-line basis over the lease term. All of the Company’s leases have been classified as operating leases. Operating leases in excess of 12 months are recognized on the balance sheet, with future lease payments recognized as a liability, measured at present value, and the right-of-use asset recognized for the lease term. A single lease cost is recognized in the income statement over the lease term.
Revenues	Disaggregation of revenue We disaggregate revenue from contracts with customers based on the ship to location of the customer. The geographic regions that are reviewed are the United States and countries outside of the United States (primarily located in Asia). Total net sales based on the disaggregation criteria described above are as follows: Three Months Ended Six Months Ended September 28, September 29, September 28, September 29, 2019 2018 2019 2018 Non-United States $ 385,222 $ 359,685 $ 619,263 $ 605,307 United States 3,690 6,620 7,902 15,481 $ 388,912 $ 366,305 $ 627,165 $ 620,788 Performance obligations The Company's single performance obligation is the delivery of promised goods to the customer. The promised goods are explicitly stated in the customer contract and are comprised of either a single type of good or a series of goods that are substantially the same, have the same pattern of transfer to the customer, and are neither capable of being distinct nor separable from the other promised goods in the contract. This performance obligation is satisfied upon transfer of control of the promised goods to the customer, as defined per the shipping terms within the customer's contract. The vast majority of the Company's contracts with customers have an original expected term length of one year or less. As allowed by ASC 606, the Company has not disclosed the value of any unsatisfied performance obligations related to these contracts. The Company’s products primarily include a warranty period of one Guarantees , and are not considered a separate performance obligation. Contract balances Payments are typically due within 30 to 60 days of invoicing and terms do not include a significant financing components or noncash consideration. There have been no material impairment losses on accounts receivable. There are no material contract assets or contract liabilities recorded on the consolidated condensed balance sheets. Transaction price The transaction price is the amount of consideration to which the Company expects to be entitled in exchange for transferring the promised goods to the customer. Fixed pricing is the consideration that is agreed upon in the customer contract. Variable pricing includes rebates, rights of return, warranties, price protection and stock rotation. Rebates are granted as a customer account credit, based on agreed-upon sales thresholds. Rights of return and warranty costs are estimated using the "most likely amount" method by reviewing historical returns to determine the most likely customer return rate and applying materiality thresholds. Price protection includes price adjustments available to certain distributors based upon established book price and a stated adjustment period. Stock rotation is also available to certain distributors based on a stated maximum of prior billings. The Company estimates all variable consideration at the most likely amount that it expects to be entitled. The estimate is based on current and historical information, including recent sales activity and pricing, available to the Company. Variable consideration is only included in the transaction price to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The Company defers all variable consideration that does not meet the revenue recognition criteria.
Segment Information	We determine our operating segments in accordance with FASB guidelines. Our Chief Executive Officer (“CEO”) has been identified as the chief operating decision maker under these guidelines. The Company operates and tracks its results in one reportable segment, but reports revenue in two product lines, Portable and Non-Portable and Other. Our CEO receives and uses enterprise-wide financial information to assess financial performance and allocate resources, rather than detailed information at a product line level. Additionally, our product lines have similar characteristics and customers. They share support functions such as sales, public relations, supply chain management, various research and development and engineering support, in addition to the general and administrative functions of human resources, legal, finance and information technology. Therefore, there is no complete, discrete financial information maintained for these product lines.

Securities in a continuous unrealized loss position for more than 12 months as of September 28, 2019 had an aggregate amortized cost of $5.5 million and an immaterial amount of aggregate unrealized loss. The Company may sell certain of its marketable securities prior to their stated maturities for strategic reasons including, but not limited to, anticipated or actual changes in credit rating and duration management. When evaluating an investment for other-than-temporary impairment, the Company reviews factors including the length of time and extent to which fair value has been below cost basis, the financial condition of the issuer, changes in market interest rates and whether it is more likely than not the Company will be required to sell the investment before recovery of the investment’s cost basis. As of September 28, 2019, the Company did not consider any of its investments to be other-than-temporarily impaired.
