Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Accounting, Policy | Skyworks Solutions, Inc., together with its consolidated subsidiaries (“Skyworks” or the “Company”), is empowering the wireless networking revolution. The Company’s analog and mixed-signal semiconductors are connecting people, places, and things, spanning a number of new applications within the aerospace, automotive, broadband, cellular infrastructure, connected home, defense, entertainment and gaming, industrial, medical, smartphone, tablet, and wearable markets. The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. Certain information and footnote disclosures, normally included in annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”), have been condensed or omitted pursuant to those rules and regulations. However, in management’s opinion, the financial information reflects all adjustments, including those of a normal recurring nature, necessary to present fairly the results of operations, financial position, and cash flows of the Company for the periods presented. The results of operations, financial position, and cash flows for the Company during the interim periods are not necessarily indicative of those expected for the full year. This information should be read in conjunction with the Company’s financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended September 29, 2023, filed with the SEC on November 17, 2023, as amended by Amendment No. 1 to such Annual Report on Form 10-K, filed with the SEC on January 26, 2024 (“2023 10-K”). Certain items in the prior period financial statements have been reclassified to conform to the current period presentation. 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 that are reported during the reporting period. The Company evaluates its estimates on an ongoing basis using historical experience and other factors, including the current economic environment. Judgment is required in determining the reserves for, and fair value of, items such as overall fair value assessments of assets and liabilities, particularly those classified as Level 2 or Level 3 in the fair value hierarchy, marketable securities, inventory, intangible assets associated with business combinations, share-based compensation, revenue reserves, loss contingencies, and income taxes. In addition, 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.
Fiscal Period | The Company’s fiscal year ends on the Friday closest to September 30. The fiscal year ending on September 27, 2024 consists of 52 weeks (“fiscal 2024”). The fiscal year ended on September 29, 2023 consisted of 52 weeks (“fiscal 2023”). The three and six months ended March 29, 2024, and March 31, 2023, each consisted of 13 weeks and 26 weeks, respectively.
Property, Plant, and Equipment, Policy | 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 forty years for buildings and improvements and from five 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.
Use of Estimates, Policy | During the six months ended March 29, 2024, the Company changed its accounting estimate for the expected useful lives of certain machinery and equipment. The Company evaluated its current asset base and reassessed the estimated useful lives of certain machinery and equipment in connection with its recent usage of older equipment, including considering the technological and physical obsolescence of such machinery and equipment. Based on its ability to re-use equipment across generations of process technologies and historical usage trends, the Company determined that the expected useful lives for certain machinery and equipment should be increased by up to two years to reflect more closely the estimated economic lives of those assets. This change in estimate was applied prospectively effective during the first quarter of fiscal 2024 and resulted in a decrease in depreciation expense of $18.9 million and $37.7 million for the three and six months ended March 29, 2024, respectively. This benefit decreased cost of goods sold by $1.8 million for each of the three and six months ended March 29, 2024, respectively, decreased research and development expenses by $2.5 million and $4.9 million for the three and six months ended March 29, 2024, respectively, and decreased ending inventory by $31.0 million as of March 29, 2024. As a result of this change in accounting estimate, net income increased by $4.3 million and $6.7 million and diluted earnings per share increased by $0.03 and $0.04 for the three and six months ended March 29, 2024, respectively.
Recently Issued Accounting Pronouncements, Policy | Recently Issued Accounting Pronouncements In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosure” (“ASU 2023-07”). ASU 2023-07 requires disclosure of incremental segment information on an annual and interim basis. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, on a retrospective basis. Early adoption is permitted. The Company is currently evaluating the impact of ASU 2023-07 on its consolidated financial statements and related disclosures. In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”). ASU 2023-09 includes amendments that further enhance income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, on either a prospective or retrospective basis, with early adoption permitted. The Company is currently evaluating the impact of ASU 2023-09 on its consolidated financial statements and related disclosures.
