| SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES PRINCIPLES OF CONSOLIDATION All Skyworks subsidiaries are included in the Company’s consolidated financial statements and all intercompany balances are eliminated in consolidation. FISCAL YEAR The Company’s fiscal year ends on the Friday closest to September 30. Fiscal 2018, 2017, and 2016 each consisted of 52 weeks and ended on September 28, 2018, September 29, 2017, and September 30, 2016, respectively. USE OF ESTIMATES The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts of assets, liabilities, revenue, expenses, comprehensive income and accumulated other comprehensive loss during the reporting period. The Company evaluates its estimates on an ongoing basis using historical experience and other factors, including the current economic environment. Significant judgment is required in determining the reserves for and fair value of items such as overall fair value assessments of assets and liabilities, inventory, intangible assets associated with business combinations, share-based compensation, loss contingencies, and income taxes. In addition, significant judgment is required in determining whether a potential indicator of impairment of long-lived assets exists and in estimating future cash flows for any necessary impairment testing. Actual results could differ significantly from these estimates. CASH AND CASH EQUIVALENTS The Company invests excess cash in time deposits, certificate of deposits, money market funds, U.S. Treasury securities, agency securities, other government securities, corporate debt securities and commercial paper. The Company considers highly liquid investments with maturities of 90 days or less when purchased as cash equivalents. ALLOWANCE FOR DOUBTFUL ACCOUNTS The Company maintains general allowances for doubtful accounts related to potential losses that could arise due to customers’ inability to make required payments. These reserves require management to apply judgment in deriving these estimates. In addition, the Company performs ongoing credit evaluations of its customers’ financial condition and if it becomes aware of any specific receivables which may be uncollectable, it performs additional analysis including, but not limited to, factors such as a customer’s credit worthiness, intent and ability to pay and overall financial position, and reserves are recorded if deemed necessary. If the data the Company uses to calculate the allowance for doubtful accounts does not reflect the future ability to collect outstanding receivables, additional provisions for doubtful accounts may be needed and results of operations could be materially affected. INVESTMENTS The Company classifies its investment in marketable securities as “available-for-sale.” Available-for-sale securities are carried at fair value with unrealized holding gains or losses recorded in other comprehensive income. Gains or losses are included in earnings in the period in which they are realized. FAIR VALUE Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principle or most advantageous market in an orderly transaction between market participants at the measurement date. Applicable accounting guidance provides a hierarchy for inputs used in measuring fair value that prioritize the use of observable inputs over the use of unobservable inputs, when such observable inputs are available. The three levels of inputs that may be used to measure fair value are as follows: • Level 1 - Quoted prices in active markets for identical assets or liabilities. • Level 2 - Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets with insufficient volume or infrequent transactions (less active markets), or model-driven valuations in which all significant inputs are observable or can be derived principally from, or corroborated with, observable market data. • Level 3 - Fair value is derived from valuation techniques in which one or more significant inputs are unobservable, including assumptions and judgments made by the Company. It is the Company’s policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements. When available, the Company uses quoted market prices to measure fair value. If market prices are not available, the Company is required to make judgments about assumptions market participants would use to estimate the fair value of a financial instrument. The Company measures certain assets and liabilities at fair value on a recurring basis in three levels, based on the market in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. It recognizes transfers within the fair value hierarchy at the end of the fiscal quarter in which the change in circumstances that caused the transfer occurred. The carrying value of cash and cash equivalents, accounts receivable, other current assets, accounts payable and accrued liabilities approximates fair value due to the short-term maturities of these assets and liabilities. INVENTORY Inventory is stated at the lower of cost or net realizable value on a first-in, first-out basis. Reserves for excess and obsolete inventory are established on a quarterly basis and are based on a detailed analysis of aged material, forecasted demand in relation to on-hand inventory, salability of our inventory, general market conditions, and product life cycles. Once reserves are established, write-downs of inventory are considered permanent adjustments to the cost basis of inventory. PROPERTY, PLANT AND EQUIPMENT Property, plant and equipment are carried at cost less accumulated depreciation, with significant renewals and betterments being capitalized and retired equipment written off in the respective periods. Maintenance and repairs are expensed as incurred. Depreciation is calculated using the straight-line method over the estimated useful lives, which range from five to thirty years for buildings and improvements and three to ten years for machinery and equipment. Leasehold improvements are depreciated over the lesser of the economic life or the life of the associated lease. VALUATION OF LONG-LIVED ASSETS Definite lived intangible assets are carried at cost less accumulated amortization. Amortization is calculated based on the pattern of benefit to be recognized from the underlying asset over its estimated useful life. Carrying values for long-lived assets and definite lived intangible assets are reviewed for possible impairment as circumstances warrant. Factors considered important that could result in an impairment review include significant underperformance relative to expected, historical or projected future operating results, significant changes in the manner of use of assets or the Company’s business strategy, or significant negative industry or economic trends. In addition, impairment reviews are conducted at the judgment of management whenever asset values are deemed to be unrecoverable relative to future undiscounted cash flows expected to be generated by that particular asset group. The determination of recoverability is based on an estimate of undiscounted cash flows expected to result from the use of an asset group and its eventual disposition. Such estimates require management to exercise judgment and make assumptions regarding factors such as future revenue streams, operating expenditures, cost allocation and asset utilization levels, all of which collectively impact future operating performance. The Company’s estimates of undiscounted cash flows may differ from actual cash flows due to, among other things, technological changes, economic conditions, changes to its business model or changes in its operating performance. If the sum of the undiscounted cash flows is less than the carrying value of an asset group, the Company would recognize an impairment loss, measured as the amount by which the carrying value exceeds the fair value of the asset group. GOODWILL AND INDEFINITE-LIVED INTANGIBLE ASSETS Goodwill and indefinite-lived intangible assets are not amortized but are tested at least annually as of the first day of the fourth fiscal quarter for impairment or more frequently if indicators of impairment exist during the fiscal year. The Company assesses its conclusion regarding segments and reporting units in conjunction with its annual goodwill impairment test, and has determined that it has one reporting unit for the purposes of allocating and testing goodwill. The Company’s impairment analysis compares its fair value to its net book value to determine if there is an indicator of impairment. In the Company’s calculation of fair value, it considers the closing price of its common stock on the selected testing date, the number of shares of its common stock outstanding and other marketplace activity such as a related control premium. If the calculated fair value is determined to be less than the book value of the reporting unit, an impairment loss is recognized equal to that excess; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. BUSINESS COMBINATIONS The Company uses the acquisition method of accounting for business combinations and recognizes assets acquired and liabilities assumed at their fair values on the date acquired. Goodwill represents the excess of the purchase price over the fair value of the net assets. The fair values of the assets and liabilities acquired are determined based upon the Company’s valuation using a combination of market, income or cost approaches. The valuation involves making significant estimates and assumptions, which are based on detailed financial models including the projection of future cash flows, the weighted average cost of capital and any cost savings that are expected to be derived in the future from the viewpoint of a market participant. EMPLOYEE RETIREMENT BENEFIT PLANS The funded status of benefit pension plans, or the balance of plan assets and benefit obligations, is recognized on the consolidated balance sheet and pension liability adjustments, net of tax, are recorded in Accumulated Other Comprehensive Income. The Company determines discount rates considering the rates of return on high-quality fixed income investments, and the expected long-term rate of return on pension plan assets by considering the current and expected asset allocations, as well as historical and expected returns on various categories of plan assets. Decreases in discount rates lead to increases in benefit obligations that, in turn, could lead to an increase in amortization cost through amortization of actuarial gain or loss. A decline in the market values of plan assets will generally result in a lower expected rate of return, which would result in an increase of future retirement benefit costs. REVENUE RECOGNITION Revenue from product sales is recognized when there is persuasive evidence of an arrangement, the price to the buyer is fixed and determinable, delivery and transfer of title have occurred in accordance with the shipping terms specified in the arrangement with the customer and collectability is reasonably assured. Revenue from license fees and intellectual property is recognized when due and payable, and all other criteria previously noted have been met. The Company ships product on consignment to certain customers and only recognizes revenue when the customer notifies the Company that the inventory has been consumed. Revenue recognition is deferred in all instances where the earnings process is incomplete. Certain product sales are made to electronic component distributors under agreements allowing for price protection and stock rotation on unsold products. Reserves for sales returns and allowances are recorded based on historical experience or pursuant to contractual arrangements necessitating revenue reserves. Reserves for sales returns and allowances of $32.2 million and $14.7 million were recorded as of September 28, 2018 and September 29, 2017 , respectively. SHARE-BASED COMPENSATION The Company recognizes compensation expense for all share-based payment awards made to employees and directors including non-qualified employee stock options, share awards and units, employee stock purchase plan and other special share-based awards based on estimated fair values. The fair value of share-based payment awards is amortized over the requisite service period, which is defined as the period during which an employee is required to provide service in exchange for an award. The Company uses a straight-line attribution method for all grants that include only a service condition. Awards with both performance and service conditions are expensed over the service period for each separately vesting tranche. Share-based compensation expense recognized during the period includes actual expense on vested awards and expense associated with unvested awards. Forfeitures are recorded as incurred. The Company determines the fair value of share-based option awards based on the Company’s closing stock price on the date of grant using a Black-Scholes options pricing model. Under the Black-Scholes model, a number of variables are used including, but not limited to: the expected stock price volatility over the term of the award, the risk-free rate, the expected life of the award and dividend yield. The determination of fair value of restricted and certain performance share awards and units is based on the value of the Company’s stock on the date of grant with performance awards and units adjusted for the actual outcome of the underlying performance condition. For more complex performance awards including units with market-based performance conditions the Company employs a Monte Carlo simulation valuation method to calculate the fair value of the awards based on the most likely outcome. Under the Monte Carlo simulation, a number of highly complex and subjective variables are used including, but not limited to: the expected stock price volatility over the term of the award, a correlation coefficient, the risk-free rate, the expected life of the award, and dividend yield. RESEARCH AND DEVELOPMENT COSTS Research and development costs are expensed as incurred. LOSS CONTINGENCIES The Company records its best estimates of a loss contingency when it is considered probable and the amount can be reasonably estimated. When a range of loss can be reasonably estimated with no best estimate in the range, the minimum estimated liability related to the claim is recorded. As additional information becomes available, the Company assesses the potential liability related to the potential pending loss contingency and revises its estimates. Loss contingencies are disclosed if there is at least a reasonable possibility that a loss or an additional loss may have been incurred and include estimated legal costs. RESTRUCTURING 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. Contract exit costs include contract termination fees and future contractual commitments for lease payments. A liability for contract exit costs is recognized in the period in which the Company terminates the contract or on the cease-use date for leased facilities. FOREIGN CURRENCIES The Company’s primary functional currency is the United States dollar. Gains and losses related to foreign currency transactions, conversion of foreign denominated cash balances and translation of foreign currency financial statements are included in current results. For certain foreign entities that utilize local currencies as their functional currency, the resulting unrealized translation gains and losses are reported as currency translation adjustment through other comprehensive income (loss) for each period. INCOME TAXES The Company uses the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. This method also requires the recognition of future tax benefits such as net operating loss carry forwards, to the extent that realization of such benefits is more likely than not. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The carrying value of the Company’s net deferred tax assets assumes the Company will be able to generate sufficient future taxable income in certain tax jurisdictions, based on estimates and assumptions. If these estimates and related assumptions change in the future, the Company may be required to record additional valuation allowances against its deferred tax assets resulting in additional income tax expense in its Consolidated Statement of Operations. Management evaluates the realizability of the deferred tax assets and assesses the adequacy of the valuation allowance quarterly. Likewise, in the event the Company were to determine that it would be able to realize its deferred tax assets in the future in excess of their net recorded amount, an adjustment to the deferred tax assets would increase income or decrease the carrying value of goodwill in the period such determination was made. The determination of recording or releasing tax valuation allowances is made, in part, pursuant to an assessment performed by management regarding the likelihood that the Company will generate future taxable income against which benefits of its deferred tax assets may or may not be realized. This assessment requires management to exercise significant judgment and make estimates with respect to its ability to generate revenues, gross profits, operating income and taxable income in future periods. Amongst other factors, management must make assumptions regarding overall business and semiconductor industry conditions, operating efficiencies, the Company’s ability to develop products to its customers’ specifications, technological change, the competitive environment and changes in regulatory requirements which may impact its ability to generate taxable income and, in turn, realize the value of its deferred tax assets. The calculation of the Company’s tax liabilities includes addressing uncertainties in the application of complex tax regulations and is based on the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Company recognizes liabilities for anticipated tax audit issues in the United States and other tax jurisdictions based on its recognition threshold and measurement attribute of whether it is more likely than not that the positions the Company has taken in tax filings will be sustained upon tax audit, and the extent to which, additional taxes would be due. If payment of these amounts ultimately proves to be unnecessary, the reversal of the liabilities would result in tax benefits being recognized in the period in which it is determined the liabilities are no longer necessary. If the estimate of tax liabilities proves to be less than the ultimate assessment, a further charge to expense would result. The Company recognizes any interest or penalties, if incurred, on any unrecognized tax liabilities or benefits as a component of income tax expense. 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 the assumed issuance of common stock under the stock purchase plan using the treasury share method. RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-09, Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”) , which is intended to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The Company adopted ASU 2016-09 at the beginning of the first quarter of fiscal 2018. As a result of adoption, the Company recognized a discrete income tax benefit of $25.6 million to the income tax provision for excess tax benefits generated by the settlement of share-based awards during fiscal 2018. The adoption also resulted in an increase in cash flow from operations and a decrease of cash flow from financing of $25.6 million during fiscal 2018. Prior periods have not been adjusted. The Company has elected to account for forfeitures as they occur and will no longer estimate future forfeitures. The change in accounting for forfeitures was applied using a modified retrospective transition method and resulted in a cumulative-effect adjustment to retained earnings as of the beginning of the first quarter of fiscal 2018 in the amount of $1.9 million . Forfeitures in the future will now be recorded as a benefit in the period they are realized. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). This ASU simplifies the subsequent measurement of goodwill and eliminates Step 2 from the goodwill impairment test. The annual or interim goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount, and an impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. In addition, income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. The Company early adopted ASU 2017-04 during the second quarter of fiscal 2018 and applied it prospectively, as permitted by the standard. The adoption of this standard did not impact the Company’s consolidated financial statements. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS In August 2015, the FASB deferred the effective date of ASU 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition guidance. The new guidance is required to be applied retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying it recognized at the date of initial application. The Company will adopt this guidance during the first quarter of fiscal 2019 and will apply the modified retrospective approach, with the cumulative effect of applying the new guidance recognized as an adjustment to the opening retained earnings balance. The Company has established a cross-functional team to assess the potential impact of the new revenue standard. The assessment process consists of reviewing the Company’s current accounting policies and practices to identify potential differences that would result from applying the requirements of the new standard to its revenue contracts and identifying appropriate changes to the business processes, systems and controls to support revenue recognition and disclosure requirements under the new standard. The Company has determined the impact of the new revenue standard on its business processes, systems, controls and consolidated financial statements is not material. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”). This ASU requires lessees to reflect most leases on their balance sheet as assets and obligations. The effective date for the standard is for fiscal years beginning after December 15, 2018, with early adoption permitted. The standard is to be applied under the modified retrospective method, with elective reliefs, which requires application of the new guidance for all periods presented. The Company is currently evaluating the effect that ASU 2016-02 will have on the consolidated financial statements and related disclosures. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), (“ASU 2016-15”). This ASU provides guidance on the presentation and classification of specific cash flow items to improve consistency within the statement of cash flows. The effective date for the standard is for fiscal years beginning after December 15, 2017, with early adoption permitted. The Company will early adopt ASU 2016-15 during the first quarter of fiscal 2019 and does not expect it to have a material impact on the consolidated financial statements. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740), Intra-entity Transfers of an Asset Other than Inventory (“ASU 2016-16”). This ASU provides guidance that changes the accounting for income tax effects of intra-entity transfers of assets other than inventory. Under the new guidance, the selling (transferring) entity is required to recognize a current tax expense or benefit upon transfer of the asset. Similarly, the purchasing (receiving) entity is required to recognize a deferred tax asset or deferred tax liability, as well as the related deferred tax benefit or expense, upon receipt of the asset. The effective date for the standard is for fiscal years beginning after December, 15, 2017, on a modified retrospective basis, and early adoption is permitted. The Company will early adopt ASU 2016-16 during the first quarter of fiscal 2019 and does not expect it to have a material impact on the consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718), Scope of Modification Accounting (“ASU 2017-09”). This ASU provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. The effective date for the standard is for interim periods in fiscal years beginning after December 15, 2017, with early adoption permitted, including adoption in any interim period for which financial statements have not yet been issued. The Company will early adopt ASU 2017-09 during the first quarter of fiscal 2019 and does not expect it to have a material impact on the consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments (Topic 320), (“ASU 2016-13”). This ASU requires a financial asset (or a group of financial assets) measured on the basis of amortized cost to be presented at the net amount expected to be collected. This ASU requires that the income statement reflect the measurement of credit losses for newly recognized financial assets as well as the expected increases or decreases of expected credit losses that have taken place during the period. This ASU requires that credit losses of debt securities designated as available-for-sale be recorded through an allowance for credit losses. The ASU also limits the credit loss to the amount by which fair value is below amortized cost. This ASU will be effective for the Company in the first quarter of 2021, with early adoption permitted. This ASU requires modified retrospective adoption, with prospective adoption for debt securities for which an other-than-temporary impairment had been recognized before the effective date. The Company is currently evaluating the effect ASU 2016-13 will have on the consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (Topic 320), (“ASU 2016-01”). This ASU provides guidance for the recognition, measurement, presentation, and disclosure of financial assets and liabilities. This ASU will be effective for the Company in the first quarter of fiscal 2019 and requires modified retrospective adoption, with prospective adoption for amendments related to equity securities without readily determinable fair values. The Company is evaluating the effect ASU 2016-01 will have on the consolidated financial statements. In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718), Improvements to Nonemployee Share-based Payments (“ASU 2018-07”). This ASU expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. The effective date for the standard is for interim periods in fiscal years beginning after December 15, 2018, with early adoption permitted, but no earlier than the Company's adoption date of Topic 606. The new guidance is required to be applied retrospectively with the cumulative effect recognized at the date of initial application. The Company will early adopt ASU 2018-07 during the first quarter of fiscal 2019 and does not expect it to have a material impact on the consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement - Disclosure Framework (Topic 820), (“ASU 2018-13”) . The updated guidance improves the disclosure requirements on fair value measurements. The updated guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted for any removed or modified disclosures. The Company early adopted the removed or modified disclosures in the fourth quarter of fiscal 2018 and is currently assessing the timing and impact of adopting the updated provisions. There have been no other recent accounting pronouncements or changes in accounting pronouncements that are of significance, or potential significance, to the Company. Supplemental Cash Flow Information As of September 28, 2018 , the Company had $13.9 million accrued to other long-term liabilities for capital equipment, and $94.1 million accrued to accounts payable for capital equipment. These amounts accrued for capital equipment purchases have been excluded from the consolidated statements of cash flows for fiscal 2018 and are expected to be paid in subsequent periods. The prior period amount under the description “Proceeds from employee stock purchase plan” has been reclassified from net cash provided by operating activities to net cash used in financing activities. |
