Accounting Policies [Abstract]
Summary of Significant Accounting Policies [Text Block]	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Such estimates relate to the useful lives and fair value of fixed assets, valuation allowance for deferred tax assets, reserves relating to uncertain tax positions, allowances for doubtful accounts, customer returns and allowances, allowance for distributor credits, inventory valuation, reserves relating to litigation matters, assumptions about the fair value of reporting units, accrued liabilities and reserves, assumptions related to the calculation of stock-based compensation and the value of intangibles acquired and goodwill associated with business combinations. The Company bases its estimates and judgments on its historical experience, knowledge of current conditions and its beliefs of what could occur in the future, given available information. Actual results may differ from those estimates, and such differences may be material to the financial statements. Basis of Presentation The consolidated financial statements include the accounts of the Company and all of its majority-owned subsidiaries. Intercompany balances and transactions have been eliminated in consolidation. Cash Equivalents and Investments The Company considers all highly liquid financial instruments purchased with an original maturity of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents consist of demand accounts, money market funds, U.S. Treasury securities, agency securities, corporate debt securities, certificates of deposit, and commercial paper. Short-term investments consist primarily of U.S. treasury debt securities with original maturities beyond three months at the date of purchase, agency securities, corporate debt securities, certificates of deposit, and commercial paper. The Company's short-term investments are considered available-for-sale and classified as short-term as these investments generally consist of highly marketable securities that are available to meet near-term cash requirements. Such securities are carried at fair market value based on market quotes and other observable inputs. Unrealized gains and losses, net of tax, on securities in this category are reported as equity in the Consolidated Statement of Comprehensive Income. Realized gains and losses on sales of investment securities are determined based on the specific identification method and are included in Interest and other income (expense), net in the Consolidated Statements of Income. The Company's long-term equity investments consist of investments in privately-held companies without readily determinable fair values and are included in Other assets on the Consolidated Balance Sheets. Equity investments are measured using the measurement alternative, which is defined as cost, less impairment, adjusted for observable price changes from orderly transactions for identical or similar investments of the same issuer. The Company uses various inputs to evaluate equity investments including valuations of recent financing events as well as other information regarding the issuer’s historical and forecasted performance. Derivative Instruments The Company incurs expenditures denominated in non-U.S. currencies, primarily the Philippine Peso and the Thai Baht associated with the Company's manufacturing activities in the Philippines and Thailand, respectively, and European Euro, Indian Rupee, Taiwan New Dollar, South Korean Won, Chinese Yuan, Japanese Yen, Singapore Dollar, and Canadian Dollar expenditures for sales offices and research and development activities undertaken outside of the U.S. The Company is exposed to fluctuations in foreign currency exchange rates for cash flows for expenditures and on orders and accounts receivable from sales in these foreign currencies. The Company has established risk management strategies designed to reduce the impact of volatility of future cash flows caused by changes in the exchange rate for these currencies. These strategies reduce, but do not entirely eliminate, the impact of currency exchange rates movements. Currency forward contracts are used to offset the currency risk of non-U.S. dollar-denominated assets and liabilities. The Company typically enters into currency forward contracts to hedge exposures associated with its expenditures denominated in European Euro, Philippine Peso and South Korean Won. The Company also hedges smaller expense exposures in several other foreign currencies. The Company enters into currency forward contracts to hedge its accounts receivable and backlog denominated in European Euro, Japanese Yen and British Pound. Changes in fair value of the underlying assets and liabilities are generally offset by the changes in fair value of the related currency forward contract. The Company uses currency forward contracts to hedge exposure to variability in anticipated non-U.S. dollar-denominated cash flows. These contracts are designated as cash flow hedges and recorded on the Consolidated Balance Sheets at their fair market value. The maturities of these instruments are generally less than six months. For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gain or loss on the derivative is reported as a component of accumulated other comprehensive income (loss) and reported within the Consolidated Statements of Comprehensive Income. These amounts have been reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. For derivative instruments that are not designated as hedging instruments, gains and losses are recognized immediately in “Interest income (expense) and other, net” in the Consolidated Statements of Income. Fair Value of Financial Instruments The Company measures certain financial assets and liabilities at fair value based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. Inventories Inventories are stated at the lower of (i) standard cost, which approximates actual cost on a first-in-first-out basis, or (ii) net realizable value. The Company's standard cost revision policy is to monitor manufacturing variances and revise standard costs on a quarterly basis. Because of the cyclical nature of the market, inventory levels, obsolescence of technology, and product life cycles, the Company generally writes down inventories to net realizable value based on forecasted product demand. Property, Plant and Equipment Property, plant and equipment are stated at cost. Depreciation is primarily computed on the straight-line method over the estimated useful lives of the assets, which range from 2 to 15 years for machinery, equipment and software and up to 40 years for buildings and building improvements. Leasehold improvements are amortized over the lesser of their useful lives or the remaining term of the related lease. When assets are retired or otherwise disposed of, the cost and accumulated depreciation or amortization is removed from the accounts and any resulting gain or loss is reflected in the Consolidated Statements of Income. The classification is based mainly on whether the asset is operating or not. The Company evaluates the recoverability of property, plant and equipment in accordance with Accounting Standards Codification (“ASC”) No. 360, Property, Plant, and Equipment (“ASC 360”). The Company performs periodic reviews to determine whether facts and circumstances exist that would indicate that the carrying amounts of property, plant and equipment are not recoverable and exceed their fair values. If facts and circumstances indicate that the carrying amounts of property, plant and equipment might not be fully recoverable, projected undiscounted net cash flows associated with the related asset or group of assets over their estimated remaining useful lives are compared against their respective carrying amounts. In the event that the projected undiscounted cash flows are not sufficient to recover the carrying value of the assets, the assets are written down to their estimated fair values based on their expected discounted future cash flows attributable to those assets. All long-lived assets classified as held for sale are reported at the lower of carrying amount or fair market value, less expected selling costs. Intangible Assets and Goodwill The Company accounts for intangible assets in accordance with ASC No. 350, Intangibles-Goodwill and Other (“ASC 350”). The Company reviews goodwill and purchased intangible assets for impairment annually in the fourth fiscal quarter and whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable, such as when reductions in demand or significant economic slowdowns in the semiconductor industry are present. Intangible asset reviews are performed when indicators exist that could indicate the carrying value may not be recoverable based on comparisons to undiscounted expected future cash flows. If this comparison indicates that there is impairment, the impaired asset is written down to fair value, which is typically calculated using: (i) quoted market prices or (ii) discounted expected future cash flows utilizing a discount rate consistent with the guidance provided in FASB Concepts Statement No. 7, Using Cash Flow Information and Present Value in Accounting Measurements. Impairment is based on the excess of the carrying amount over the fair value of those assets. Goodwill represents the excess of the purchase price in a business combination over the fair value of net tangible and intangible assets acquired. In accordance with ASC 350, the Company tests goodwill for impairment at the reporting unit level (operating segment or one level below an operating segment) on an annual basis or more frequently if the Company believes indicators of impairment exist. In accordance with ASC 350-20-35-3, the Company performs a qualitative assessment to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, as a result of the qualitative assessment, the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then the Company performs the quantitative goodwill impairment test. This test involves comparing the fair values of the applicable reporting units with their aggregate carrying values, including goodwill. The Company determines the fair value of the Company's reporting units using the income approach methodology of valuation that includes the discounted cash flow method as well as the market approach which includes the guideline company method. If the carrying amount of a reporting unit exceeds the reporting unit's fair value, the Company recognizes an impairment of goodwill measured as the amount by which a reporting unit’s carrying value exceeds its fair value with the loss recognized not to exceed the total amount of goodwill allocated to the reporting unit. Product Warranty The Company generally warrants its products for one year from the date of shipment against defects in materials, workmanship and material non-conformance to the Company’s specifications. The general warranty policy provides for the repair or replacement of defective products or a credit to the customer’s account. In limited circumstances, the Company may consider extending its warranty for up to five years. It may also include limited financial responsibility, such as the payment of monetary compensation to reimburse a customer for its financial losses beyond repairing or replacing the product or crediting the customer’s account should the product not meet the Company’s specifications, or to reimburse a customer for losses or damages that result from the defective product. Accruals are based on specifically identified claims and on the estimated, undiscounted cost of incurred-but-not-reported claims. If there is a material increase in the rate of customer claims compared with the Company's historical experience or if the Company's estimates of probable losses relating to specifically identified warranty exposures require revision, the Company may record a charge against future cost of sales. The short-term and long-term portions of the product warranty liability are included within the balance sheet captions Accrued expenses and Other liabilities, respectively, in the accompanying Consolidated Balance Sheets. Retirement Benefits The Company provides medical benefits to certain former and current employees pursuant to certain retirement agreements. The Company also provides retirement benefits to employees located in the Philippines and in other countries. These benefits to individuals are accounted for pursuant to a documented plan under ASC No. 715, Compensation-Retirement Benefits (“ASC 715”). As of July 1, 2018, the Company adopted new accounting guidance that changed how postretirement benefit plans present net periodic benefit cost in their income statement. This new guidance required the Company to report only the service cost component as operating expense, while other components of net benefit costs are reported in other income, outside of income from operations. Unrecognized actuarial gains and losses and prior service cost are amortized on a straight-line basis over the remaining estimated service period of participants. The measurement date for the plan is fiscal year end. Income Taxes The Company accounts for income taxes using an asset and liability approach as prescribed in ASC No. 740-10, Income Taxes (“ASC 740-10”). The Company records the amount of taxes payable or refundable for the current and prior years and deferred tax assets and liabilities for the future tax consequences of events that have been recognized in the Company's financial statements or tax returns. A valuation allowance is recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. ASC 740-10 prescribes a recognition threshold and measurement framework for the financial statement reporting and disclosure of an income tax position taken or expected to be taken on a tax return. Under ASC 740-10, a tax position is recognized in the financial statements when it is more likely than not, based on the technical merits, that the position will be sustained upon examination, including resolution of any related appeals or litigation processes. A tax position that meets the recognition threshold is then measured to determine the largest amount of the benefit that has a greater than 50% likelihood of being realized upon settlement. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of the provision for income taxes in the Consolidated Statements of Income. The calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws across multiple tax jurisdictions. Although ASC 740-10 provides clarification on the accounting for uncertainty in income taxes recognized in the financial statements, the recognition threshold and measurement framework will continue to require significant judgment by management. Resolution of these uncertainties in a manner inconsistent with the Company's expectations could have a material impact on the Company's results of operations. Revenue Recognition The Company recognizes revenue for sales to direct customers and distribution customers ("distributors") when a customer obtains control of promised goods or services in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services. The transaction price is calculated as selling price net of variable considerations, such as distributor price adjustments. In determining the transaction price, the Company evaluates whether the price is subject to refund or adjustment to determine the net consideration to which it is expected to realize. The transaction price does not include amounts collected on behalf of another party, such as sales taxes or value added tax. The Company elected the practical expedient to not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which it recognizes revenue at the amount to which it has the right to invoice for services performed. The Company estimates returns for sales to direct customers and distributors based on historical return rates applied against current period gross revenue. Specific customer returns and allowances are considered within this estimate. Accounts receivable from direct customers and distributors are recognized and inventory is relieved upon shipment as title to inventories generally transfers upon shipment, at which point the Company has a legally enforceable right to collection under normal terms. Accounts receivable related to consigned inventory is recognized when the customer takes title to such inventory from its consigned location, at which point inventory is relieved, title transfers, and the Company has a legally enforceable right to collection under the terms of the agreement with the related customers. Customers are generally required to pay for products and services within the Company’s standard terms, which is net 30 days from the date of invoice. The Company estimates potential future returns and sales allowances related to current period product revenue. Management analyzes historical returns, changes in customer demand and acceptance of products when evaluating the adequacy of returns and sales allowances. Estimates made may differ from actual returns and sales allowances. These differences may materially impact reported revenue and amounts ultimately collected on accounts receivable. Historically, such differences have not been material. Distributor price adjustments are estimated based on the Company's historical experience rates and also considering economic conditions and contractual terms. To date, actual distributor claims activity has been materially consistent with the estimates that the Company has made based on its historical rates. The Company's revenue arrangements do not contain significant financing components. Revenue is recognized over a period of time when it is assessed that performance obligations are satisfied over a period rather than at a point in time. When any of the following criteria is fulfilled, revenue is recognized over a period of time: (a) The customer simultaneously receives and consumes the benefits provided by the performance completed. (b)Performance creates or enhances an asset (for example, work in process) that the customer controls as the asset is created or enhanced. (c) Performance does not create an asset with an alternative use, and has an enforceable right to payment for performance completed to date. The Company had historically recognized a portion of revenue through certain distributors at the time the distributor resold the product to its end customer (also referred to as the sell-through basis of revenue recognition) given the difficulty in estimating the ultimate price of these product shipments and amount of potential returns. The Company continuously reassesses its ability to reliably estimate the ultimate price of these products and the amount of potential returns and, over the past several years, has made investments in its systems and updates to processes around its distribution channel to improve the quality of the information for preparing such estimates. As a result of this continuous reassessment, the Company recognizes all revenue from distributors upon shipment to the distributor (also referred to as the sell-in basis of revenue recognition) as of second quarter of fiscal year 2018. Related Party Transactions A member of the Company's Board of Directors is also a member of the Board of Directors of Flextronics International Ltd. During the fiscal years ended June 29, 2019, June 30, 2018, and June 24, 2017, the Company sold approximately $44.7 million, $61.6 million, and $70.4 million, respectively, in products to Flextronics International Ltd., a contract manufacturer, in the ordinary course of its business. Research and Development Costs Research and development costs are expensed as incurred. Such costs consist primarily of expenditures for labor and benefits, masks, prototype wafers and depreciation. Shipping Costs Shipping costs billed to customers are included in net revenues and the related shipping costs are included in cost of goods sold in the Consolidated Statements of Income. Stock-Based Compensation Stock-based compensation cost is measured at the grant date, based on the fair value of the awards ultimately expected to vest and is recognized as an expense, on a straight-line basis, over the requisite service period. ASC No. 718, Compensation-Stock Compensation, allows forfeitures to be either expensed as incurred or estimated at the time of grant and revised if necessary in subsequent periods if actual forfeitures or vesting differ from those estimates. The Company has elected to estimate forfeitures at the time of grant and update if necessary. Such updates could have a material effect on the Company's operating results. Restructuring Post-employment benefits accrued for workforce reductions related to restructuring activities in the United States are accounted for under ASC No. 712, Compensation-Nonretirement Postemployment Benefits. A liability for post-employment benefits is recorded when payment is probable, the amount is reasonably estimable, and the obligation relates to rights that have vested or accumulated. In accordance with ASC No. 420, Exit or Disposal Cost Obligations, generally costs associated with restructuring activities initiated outside the United States have been recognized when they are incurred. The Company continually evaluates the adequacy of the remaining liabilities under its restructuring initiatives. Although the Company believes that these estimates accurately reflect the costs of its restructuring plans, actual results may differ, thereby requiring the Company to record additional provisions or reverse a portion of such provisions. Foreign Currency Translation and Remeasurement The U.S. dollar is the functional currency for the Company's foreign operations. Using the U.S. dollar as the functional currency, monetary assets and liabilities are remeasured at the year-end exchange rates. Certain non-monetary assets and liabilities are remeasured using historical rates. Consolidated Statements of Income are remeasured at the average exchange rates during the year. Foreign exchange gains and losses as recorded in the Consolidated Statements of Income for all periods presented were not material. Earnings Per Share Basic earnings per share are computed using the weighted average number of common shares outstanding during the period. Diluted earnings per share incorporate the potentially dilutive incremental shares issuable upon the assumed exercise of stock options, the assumed vesting of outstanding restricted stock units and market stock units, and the assumed issuance of common stock under the stock purchase plan. The number of incremental shares from the assumed issuance of common stock under the stock purchase plan is calculated by applying the treasury stock method. Litigation and Contingencies From time to time, the Company receives notices that its products or manufacturing processes may be infringing the patent or other intellectual property rights of others, notices of stockholder litigation or other lawsuits or claims against the Company. The Company periodically assesses each matter in order to determine if a contingent liability in accordance with ASC No. 450, Contingencies ("ASC 450") should be recorded. In making this determination, management may, depending on the nature of the matter, consult with internal and external legal counsel and technical experts. The Company expenses legal fees associated with consultations and defense of lawsuits as incurred. Based on the information obtained, combined with management's judgment regarding all of the facts and circumstances of each matter, the Company determines whether a contingent loss is probable and whether the amount of such loss can be estimated. Should a loss be probable and estimable, the Company records a contingent loss in accordance with ASC No. 450. In determining the amount of a contingent loss, the Company takes into consideration advice received from experts in the specific matter, current status of legal proceedings, settlement negotiations which may be ongoing, prior case history and other factors. Should the judgments and estimates made by management be incorrect, the Company may need to record additional contingent losses that could materially adversely impact its results of operations. Alternatively, if the judgments and estimates made by management are incorrect and a particular contingent loss does not occur, the contingent loss recorded would be reversed thereby favorably impacting the Company's results of operations. Pursuant to the Company's charter documents and separate written indemnification agreements, the Company has certain indemnification obligations to its current officers and directors, as well as certain former officers and directors. The indemnification agreements provide, among other things, that the Company will indemnify each of its directors and officers, under the circumstances and to the extent provided therein, for expenses, damages, judgments, fines, and settlements each may be required to pay in actions or proceedings to which he or she may be made a party by reason of his or her position or positions as a director, officer or other agent of the Company, and otherwise to the fullest extent permitted under Delaware law and the Company’s bylaws. Concentration of Credit Risk Due to the Company's credit evaluation and collection process, bad debt expenses have not been significant. Credit risk with respect to trade receivables is limited because a large number of geographically diverse customers make up the Company's customer base, thus spreading the credit risk. The Company derived approximately 46% of its fiscal year 2019 revenue from sales made through distributors which includes distribution sales to Samsung and catalog distributors. The Company's primary distributor is Avnet Electronics (“Avnet”). Avnet, like the Company's other distributors, is not an end customer, but rather serves as a channel of sale to many end users of the Company's products. Avnet accounted for 22%, 25% and 22% of revenues in fiscal years 2019, 2018 and 2017, respectively, and 21% and 22% of accounts receivable as of June 29, 2019 and June 30, 2018, respectively. Sales to Samsung, the Company's largest single end customer (through direct sales and distributors), accounted for 10% of net revenues in fiscal years 2019, 2018 and 2017, and 6% and 12% of accounts receivable as of June 29, 2019 and June 30, 2018, respectively. No other customer accounted for 10% or more of the Company's revenues in the fiscal years 2019, 2018, and 2017. One customer, WTMicroelectronics, accounted for 11% and 13% of accounts receivable as of June 29, 2019 and June 30, 2018, respectively. No other customer accounted for 10% or more of the Company's accounts receivable as of June 29, 2019 and June 30, 2018. The Company maintains cash, cash equivalents, and short-term investments with various high credit quality financial institutions, limits the amount of credit exposure to any one financial institution or instrument, and is exposed to credit risk in the event of default by these institutions to the extent of amounts recorded at the balance sheet date. To date, the Company has not incurred losses related to these investments.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Such estimates relate to the useful lives and fair value of fixed assets, valuation allowance for deferred tax assets, reserves relating to uncertain tax positions, allowances for doubtful accounts, customer returns and allowances, allowance for distributor credits, inventory valuation, reserves relating to litigation matters, assumptions about the fair value of reporting units, accrued liabilities and reserves, assumptions related to the calculation of stock-based compensation and the value of intangibles acquired and goodwill associated with business combinations. The Company bases its estimates and judgments on its historical experience, knowledge of current conditions and its beliefs of what could occur in the future, given available information. Actual results may differ from those estimates, and such differences may be material to the financial statements.

Basis of Presentation

The consolidated financial statements include the accounts of the Company and all of its majority-owned subsidiaries. Intercompany balances and transactions have been eliminated in consolidation.

Cash Equivalents and Investments

The Company considers all highly liquid financial instruments purchased with an original maturity of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents consist of demand accounts, money market funds, U.S. Treasury securities, agency securities, corporate debt securities, certificates of deposit, and commercial paper. Short-term investments consist primarily of U.S. treasury debt securities with original maturities beyond three months at the date of purchase, agency securities, corporate debt securities, certificates of deposit, and commercial paper.

The Company's short-term investments are considered available-for-sale and classified as short-term as these investments generally consist of highly marketable securities that are available to meet near-term cash requirements. Such securities are carried at fair market value based on market quotes and other observable inputs. Unrealized gains and losses, net of tax, on securities in this category are reported as equity in the Consolidated Statement of Comprehensive Income. Realized gains and losses on sales of investment securities are determined based on the specific identification method and are included in Interest and other income (expense), net in the Consolidated Statements of Income.

The Company's long-term equity investments consist of investments in privately-held companies without readily determinable fair values and are included in Other assets on the Consolidated Balance Sheets. Equity investments are measured using the measurement alternative, which is defined as cost, less impairment, adjusted for observable price changes from orderly transactions for identical or similar investments of the same issuer. The Company uses various inputs to evaluate equity investments including valuations of recent financing events as well as other information regarding the issuer’s historical and forecasted performance.

Derivative Instruments

The Company incurs expenditures denominated in non-U.S. currencies, primarily the Philippine Peso and the Thai Baht associated with the Company's manufacturing activities in the Philippines and Thailand, respectively, and European Euro, Indian Rupee, Taiwan New Dollar, South Korean Won, Chinese Yuan, Japanese Yen, Singapore Dollar, and Canadian Dollar expenditures for sales offices and research and development activities undertaken outside of the U.S. The Company is exposed to fluctuations in foreign currency exchange rates for cash flows for expenditures and on orders and accounts receivable from sales in these foreign currencies. The Company has established risk management strategies designed to reduce the impact of volatility of future cash flows caused by changes in the exchange rate for these currencies. These strategies reduce, but do not entirely eliminate, the impact of currency exchange rates movements.

Currency forward contracts are used to offset the currency risk of non-U.S. dollar-denominated assets and liabilities. The Company typically enters into currency forward contracts to hedge exposures associated with its expenditures denominated in European Euro, Philippine Peso and South Korean Won. The Company also hedges smaller expense exposures in several other foreign currencies. The Company enters into currency forward contracts to hedge its accounts receivable and backlog denominated in European Euro, Japanese Yen and British Pound. Changes in fair value of the underlying assets and liabilities are generally offset by the changes in fair value of the related currency forward contract.

The Company uses currency forward contracts to hedge exposure to variability in anticipated non-U.S. dollar-denominated cash flows. These contracts are designated as cash flow hedges and recorded on the Consolidated Balance Sheets at their fair market value. The maturities of these instruments are generally less than six months. For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gain or loss on the derivative is reported as a component of accumulated other comprehensive income (loss) and reported within the Consolidated Statements of Comprehensive Income. These amounts have been reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. For derivative instruments that are not designated as hedging instruments, gains and losses are recognized immediately in “Interest income (expense) and other, net” in the Consolidated Statements of Income.

Fair Value of Financial Instruments

The Company measures certain financial assets and liabilities at fair value based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants.

Inventories

Inventories are stated at the lower of (i) standard cost, which approximates actual cost on a first-in-first-out basis, or (ii) net realizable value. The Company's standard cost revision policy is to monitor manufacturing variances and revise standard costs on a quarterly basis. Because of the cyclical nature of the market, inventory levels, obsolescence of technology, and product life cycles, the Company generally writes down inventories to net realizable value based on forecasted product demand.

Property, Plant and Equipment

Property, plant and equipment are stated at cost. Depreciation is primarily computed on the straight-line method over the estimated useful lives of the assets, which range from 2 to 15 years for machinery, equipment and software and up to 40 years for buildings and building improvements. Leasehold improvements are amortized over the lesser of their useful lives or the remaining term of the related lease. When assets are retired or otherwise disposed of, the cost and accumulated depreciation or amortization is removed from the accounts and any resulting gain or loss is reflected in the Consolidated Statements of Income. The classification is based mainly on whether the asset is operating or not.

The Company evaluates the recoverability of property, plant and equipment in accordance with Accounting Standards Codification (“ASC”) No. 360, Property, Plant, and Equipment (“ASC 360”). The Company performs periodic reviews to determine whether facts and circumstances exist that would indicate that the carrying amounts of property, plant and equipment are not recoverable and exceed their fair values. If facts and circumstances indicate that the carrying amounts of property, plant and equipment might not be fully recoverable, projected undiscounted net cash flows associated with the related asset or group of assets over their estimated remaining useful lives are compared against their respective carrying amounts. In the event that the projected undiscounted cash flows are not sufficient to recover the carrying value of the assets, the assets are written down to their estimated fair values based on their expected discounted future cash flows attributable to those assets. All long-lived assets classified as held for sale are reported at the lower of carrying amount or fair market value, less expected selling costs.

Intangible Assets and Goodwill

The Company accounts for intangible assets in accordance with ASC No. 350, Intangibles-Goodwill and Other (“ASC 350”). The Company reviews goodwill and purchased intangible assets for impairment annually in the fourth fiscal quarter and whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable, such as when reductions in demand or significant economic slowdowns in the semiconductor industry are present.

Intangible asset reviews are performed when indicators exist that could indicate the carrying value may not be recoverable based on comparisons to undiscounted expected future cash flows. If this comparison indicates that there is impairment, the impaired asset is written down to fair value, which is typically calculated using: (i) quoted market prices or (ii) discounted expected future cash flows utilizing a discount rate consistent with the guidance provided in FASB Concepts Statement No. 7, Using Cash Flow Information and Present Value in Accounting Measurements. Impairment is based on the excess of the carrying amount over the fair value of those assets.

Goodwill represents the excess of the purchase price in a business combination over the fair value of net tangible and intangible assets acquired. In accordance with ASC 350, the Company tests goodwill for impairment at the reporting unit level (operating segment or one level below an operating segment) on an annual basis or more frequently if the Company believes indicators of impairment exist. In accordance with ASC 350-20-35-3, the Company performs a qualitative assessment to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, as a result of the qualitative assessment, the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then the Company performs the quantitative goodwill impairment test. This test involves comparing the fair values of the applicable reporting units with their aggregate carrying values, including goodwill. The Company determines the fair value of the Company's reporting units using the income approach methodology of valuation that includes the discounted cash flow method as well as the market approach which includes the guideline company method. If the carrying amount of a reporting unit exceeds the reporting unit's fair value, the Company recognizes an impairment of goodwill measured as the amount by which a reporting unit’s carrying value exceeds its fair value with the loss recognized not to exceed the total amount of goodwill allocated to the reporting unit.

Product Warranty

The Company generally warrants its products for one year from the date of shipment against defects in materials, workmanship and material non-conformance to the Company’s specifications. The general warranty policy provides for the repair or replacement of defective products or a credit to the customer’s account. In limited circumstances, the Company may consider extending its warranty for up to five years. It may also include limited financial responsibility, such as the payment of monetary compensation to reimburse a customer for its financial losses beyond repairing or replacing the product or crediting the customer’s account should the product not meet the Company’s specifications, or to reimburse a customer for losses or damages that result from the defective product.

Accruals are based on specifically identified claims and on the estimated, undiscounted cost of incurred-but-not-reported claims. If there is a material increase in the rate of customer claims compared with the Company's historical experience or if the Company's estimates of probable losses relating to specifically identified warranty exposures require revision, the Company may record a charge against future cost of sales. The short-term and long-term portions of the product warranty liability are included within the balance sheet captions Accrued expenses and Other liabilities, respectively, in the accompanying Consolidated Balance Sheets.

Retirement Benefits

The Company provides medical benefits to certain former and current employees pursuant to certain retirement agreements. The Company also provides retirement benefits to employees located in the Philippines and in other countries. These benefits to individuals are accounted for pursuant to a documented plan under ASC No. 715, Compensation-Retirement Benefits (“ASC 715”). As of July 1, 2018, the Company adopted new accounting guidance that changed how postretirement benefit plans present net periodic benefit cost in their income statement. This new guidance required the Company to report only the service cost component as operating expense, while other components of net benefit costs are reported in other income, outside of income from operations. Unrecognized actuarial gains and losses and prior service cost are amortized on a straight-line basis over the remaining estimated service period of participants. The measurement date for the plan is fiscal year end.

Income Taxes

The Company accounts for income taxes using an asset and liability approach as prescribed in ASC No. 740-10, Income Taxes (“ASC 740-10”). The Company records the amount of taxes payable or refundable for the current and prior years and deferred tax assets and liabilities for the future tax consequences of events that have been recognized in the Company's financial statements or tax returns. A valuation allowance is recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized.

ASC 740-10 prescribes a recognition threshold and measurement framework for the financial statement reporting and disclosure of an income tax position taken or expected to be taken on a tax return. Under ASC 740-10, a tax position is recognized in the financial statements when it is more likely than not, based on the technical merits, that the position will be sustained upon examination, including resolution of any related appeals or litigation processes. A tax position that meets the recognition threshold is then measured to determine the largest amount of the benefit that has a greater than 50% likelihood of being realized upon settlement. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of the provision for income taxes in the Consolidated Statements of Income.

The calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws across multiple tax jurisdictions. Although ASC 740-10 provides clarification on the accounting for uncertainty in income taxes recognized in the financial statements, the recognition threshold and measurement framework will continue to require significant judgment by management. Resolution of these uncertainties in a manner inconsistent with the Company's expectations could have a material impact on the Company's results of operations.

Revenue Recognition

The Company recognizes revenue for sales to direct customers and distribution customers ("distributors") when a customer obtains control of promised goods or services in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services. The transaction price is calculated as selling price net of variable considerations, such as distributor price adjustments. In determining the transaction price, the Company evaluates whether the price is subject to refund or adjustment to determine the net consideration to which it is expected to realize. The transaction price does not include amounts collected on behalf of another party, such as sales taxes or value added tax. The Company elected the practical expedient to not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which it recognizes revenue at the amount to which it has the right to invoice for services performed. The Company estimates returns for sales to direct customers and distributors based on historical return rates applied against current period gross revenue. Specific customer returns and allowances are considered within this estimate.

Accounts receivable from direct customers and distributors are recognized and inventory is relieved upon shipment as title to inventories generally transfers upon shipment, at which point the Company has a legally enforceable right to collection under normal terms. Accounts receivable related to consigned inventory is recognized when the customer takes title to such inventory from its consigned location, at which point inventory is relieved, title transfers, and the Company has a legally enforceable right to collection under the terms of the agreement with the related customers. Customers are generally required to pay for products and services within the Company’s standard terms, which is net 30 days from the date of invoice.

The Company estimates potential future returns and sales allowances related to current period product revenue. Management analyzes historical returns, changes in customer demand and acceptance of products when evaluating the adequacy of returns and sales allowances. Estimates made may differ from actual returns and sales allowances. These differences may materially impact reported revenue and amounts ultimately collected on accounts receivable. Historically, such differences have not been material.

Distributor price adjustments are estimated based on the Company's historical experience rates and also considering economic conditions and contractual terms. To date, actual distributor claims activity has been materially consistent with the estimates that the Company has made based on its historical rates.

The Company's revenue arrangements do not contain significant financing components. Revenue is recognized over a period of time when it is assessed that performance obligations are satisfied over a period rather than at a point in time. When any of the following criteria is fulfilled, revenue is recognized over a period of time:

(a) The customer simultaneously receives and consumes the benefits provided by the performance completed. (b)Performance creates or enhances an asset (for example, work in process) that the customer controls as the asset is created or enhanced. (c) Performance does not create an asset with an alternative use, and has an enforceable right to payment for performance completed to date.

The Company had historically recognized a portion of revenue through certain distributors at the time the distributor resold the product to its end customer (also referred to as the sell-through basis of revenue recognition) given the difficulty in estimating the ultimate price of these product shipments and amount of potential returns. The Company continuously reassesses its ability to reliably estimate the ultimate price of these products and the amount of potential returns and, over the past several years, has made investments in its systems and updates to processes around its distribution channel to improve the quality of the information for preparing such estimates. As a result of this continuous reassessment, the Company recognizes all revenue from distributors upon shipment to the distributor (also referred to as the sell-in basis of revenue recognition) as of second quarter of fiscal year 2018.

Related Party Transactions

A member of the Company's Board of Directors is also a member of the Board of Directors of Flextronics International Ltd. During the fiscal years ended June 29, 2019, June 30, 2018, and June 24, 2017, the Company sold approximately $44.7 million, $61.6 million, and $70.4 million, respectively, in products to Flextronics International Ltd., a contract manufacturer, in the ordinary course of its business.

Research and Development Costs

Research and development costs are expensed as incurred. Such costs consist primarily of expenditures for labor and benefits, masks, prototype wafers and depreciation.

Shipping Costs

Shipping costs billed to customers are included in net revenues and the related shipping costs are included in cost of goods sold in the Consolidated Statements of Income.

Stock-Based Compensation

Stock-based compensation cost is measured at the grant date, based on the fair value of the awards ultimately expected to vest and is recognized as an expense, on a straight-line basis, over the requisite service period. ASC No. 718, Compensation-Stock Compensation, allows forfeitures to be either expensed as incurred or estimated at the time of grant and revised if necessary in subsequent periods if actual forfeitures or vesting differ from those estimates. The Company has elected to estimate forfeitures at the time of grant and update if necessary. Such updates could have a material effect on the Company's operating results.

Restructuring

Post-employment benefits accrued for workforce reductions related to restructuring activities in the United States are accounted for under ASC No. 712, Compensation-Nonretirement Postemployment Benefits. A liability for post-employment benefits is recorded when payment is probable, the amount is reasonably estimable, and the obligation relates to rights that have vested or accumulated. In accordance with ASC No. 420, Exit or Disposal Cost Obligations, generally costs associated with restructuring activities initiated outside the United States have been recognized when they are incurred.

The Company continually evaluates the adequacy of the remaining liabilities under its restructuring initiatives. Although the Company believes that these estimates accurately reflect the costs of its restructuring plans, actual results may differ, thereby requiring the Company to record additional provisions or reverse a portion of such provisions.

Foreign Currency Translation and Remeasurement

The U.S. dollar is the functional currency for the Company's foreign operations. Using the U.S. dollar as the functional currency, monetary assets and liabilities are remeasured at the year-end exchange rates. Certain non-monetary assets and liabilities are remeasured using historical rates. Consolidated Statements of Income are remeasured at the average exchange rates during the year. Foreign exchange gains and losses as recorded in the Consolidated Statements of Income for all periods presented were not material.

Earnings Per Share

Basic earnings per share are computed using the weighted average number of common shares outstanding during the period. Diluted earnings per share incorporate the potentially dilutive incremental shares issuable upon the assumed exercise of stock options, the assumed vesting of outstanding restricted stock units and market stock units, and the assumed issuance of common stock under the stock purchase plan. The number of incremental shares from the assumed issuance of common stock under the stock purchase plan is calculated by applying the treasury stock method.

Litigation and Contingencies

From time to time, the Company receives notices that its products or manufacturing processes may be infringing the patent or other intellectual property rights of others, notices of stockholder litigation or other lawsuits or claims against the Company. The Company periodically assesses each matter in order to determine if a contingent liability in accordance with ASC No. 450, Contingencies ("ASC 450") should be recorded. In making this determination, management may, depending on the nature of the matter, consult with internal and external legal counsel and technical experts. The Company expenses legal fees associated with consultations and defense of lawsuits as incurred. Based on the information obtained, combined with management's judgment regarding all of the facts and circumstances of each matter, the Company determines whether a contingent loss is probable and whether the amount of such loss can be estimated. Should a loss be probable and estimable, the Company records a contingent loss in accordance with ASC No. 450. In determining the amount of a contingent loss, the Company takes into consideration advice received from experts in the specific matter, current status of legal proceedings, settlement negotiations which may be ongoing, prior case history and other factors. Should the judgments and estimates made by management be incorrect, the Company may need to record additional contingent losses that could materially adversely impact its results of operations. Alternatively, if the judgments and estimates made by management are incorrect and a particular contingent loss does not occur, the contingent loss recorded would be reversed thereby favorably impacting the Company's results of operations.

Pursuant to the Company's charter documents and separate written indemnification agreements, the Company has certain indemnification obligations to its current officers and directors, as well as certain former officers and directors. The indemnification agreements provide, among other things, that the Company will indemnify each of its directors and officers, under the circumstances and to the extent provided therein, for expenses, damages, judgments, fines, and settlements each may be required to pay in actions or proceedings to which he or she may be made a party by reason of his or her position or positions as a director, officer or other agent of the Company, and otherwise to the fullest extent permitted under Delaware law and the Company’s bylaws.

Concentration of Credit Risk

Due to the Company's credit evaluation and collection process, bad debt expenses have not been significant. Credit risk with respect to trade receivables is limited because a large number of geographically diverse customers make up the Company's customer base, thus spreading the credit risk. The Company derived approximately 46% of its fiscal year 2019 revenue from sales made through distributors which includes distribution sales to Samsung and catalog distributors. The Company's primary distributor is Avnet Electronics (“Avnet”). Avnet, like the Company's other distributors, is not an end customer, but rather serves as a channel of sale to many end users of the Company's products. Avnet accounted for 22%, 25% and 22% of revenues in fiscal years 2019, 2018 and 2017, respectively, and 21% and 22% of accounts receivable as of June 29, 2019 and June 30, 2018, respectively. Sales to Samsung, the Company's largest single end customer (through direct sales and distributors), accounted for 10% of net revenues in fiscal years 2019, 2018 and 2017, and 6% and 12% of accounts receivable as of June 29, 2019 and June 30, 2018, respectively. No other customer accounted for 10% or more of the Company's revenues in the fiscal years 2019, 2018, and 2017. One customer, WTMicroelectronics, accounted for 11% and 13% of accounts receivable as of June 29, 2019 and June 30, 2018, respectively. No other customer accounted for 10% or more of the Company's accounts receivable as of June 29, 2019 and June 30, 2018.

The Company maintains cash, cash equivalents, and short-term investments with various high credit quality financial institutions, limits the amount of credit exposure to any one financial institution or instrument, and is exposed to credit risk in the event of default by these institutions to the extent of amounts recorded at the balance sheet date. To date, the Company has not incurred losses related to these investments.
