Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Basis of Presentation In the opinion of our management, the unaudited interim consolidated condensed financial statements of Applied Materials, Inc. and its subsidiaries (we, us, and our) included herein have been prepared on a basis consistent with the October 29, 2023 audited consolidated financial statements and include all material adjustments, consisting of normal recurring adjustments, necessary to fairly state the information set forth therein. These unaudited interim consolidated condensed financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended October 29, 2023 (2023 Form 10-K). The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make judgments, estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ materially from those estimates. Our results of operations for the three months ended January 28, 2024 are not necessarily indicative of future operating results. Our fiscal year ends on the last Sunday in October of each year. Fiscal 2024 and 2023 contain 52 weeks each and the first three months of fiscal 2024 and 2023 each contained 13 weeks. Certain prior-year amounts have been reclassified to conform to current-year presentation. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make judgments, estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ materially from those estimates. On an ongoing basis, we evaluate our estimates, including those related to standalone selling price (SSP) related to revenue recognition, accounts receivable and sales allowances, fair values of financial instruments, inventories, intangible assets and goodwill, useful lives of intangible assets and property, plant and equipment, fair values of share-based awards, warranty, and income taxes, among others. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Property, Plant and Equipment Property, plant and equipment is stated at cost. Depreciation is provided over the estimated useful lives of the assets using the straight-line method. In connection with our periodic review of estimated useful lives of the property, plant, and equipment effective as of the beginning of fiscal 2024, we have increased the estimated useful lives of certain assets. The updated estimated useful lives for financial reporting purposes are as follows: buildings and improvements, 3 to 30 years with certain buildings and improvements’ useful lives increased by 5 years; demonstration and manufacturing equipment increased to between 5 to 8 years. The estimated useful lives for the remaining asset categories remained unchanged from fiscal 2023. The change in accounting estimate is being applied on a prospective basis to the assets on our balance sheet as of October 29, 2023, as well as to subsequent asset purchases. Based on the net carrying amounts of assets in use as of the end of fiscal 2023, the impact of this change during the three months ended January 28, 2024 was a reduction of $37 million in depreciation expense and an increase of $0.03 in both basic and diluted earnings per share. Recent Accounting Pronouncements Accounting Standards Adopted Contract Assets and Contract Liabilities from Revenue Contracts with Customers in a Business Combination. In October 2021, the Financial Accounting Standards Board (FASB) issued an accounting standard update to improve the accounting for contract assets and contract liabilities from revenue contracts with customers in a business combination (Topic 805). This amendment improves comparability for both the recognition and measurement of acquired revenue contracts with customers at the date of and after a business combination. We adopted this authoritative guidance in the first quarter of fiscal 2024 and the impact of the adoption depends on the facts and circumstances of future acquisitions. Accounting Standards Not Yet Adopted Improvements to Income Tax Disclosures. In December 2023, the FASB issued an accounting standard update to improve income tax disclosures (Topic 740). The standard prescribes specific categories for the components of the effective tax rate reconciliation, requires disclosure of income taxes paid by jurisdiction, and modifies other income tax-related disclosures. This authoritative guidance will be effective for us beginning with our annual reporting for fiscal year 2026, with early adoption permitted. We are evaluating the effect of this new guidance on our consolidated financial statements and related disclosures. Improvements to Reportable Segment Disclosures. In November 2023, the FASB issued an accounting standard update to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses (Topic 280). The standard requires interim and annual disclosure of significant segment expenses that are regularly provided to the chief operating decision-maker (CODM) and included within the reported measure of a segment’s profit or loss, requires interim disclosures about a reportable segment’s profit or loss and assets that are currently required annually, requires disclosure of the position and title of the CODM, clarifies circumstances in which an entity can disclose multiple segment measures of profit or loss and contains other disclosure requirements. This authoritative guidance will be effective for us in fiscal 2025 for annual periods and in the first quarter of fiscal 2026 for interim periods, with early adoption permitted. We are evaluating the effect of this new guidance on our consolidated condensed financial statements. Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions. In June 2022, the FASB issued an accounting standard update which clarifies how the fair value of equity securities subject to contractual sale restrictions is determined (Topic 820). The amendment clarifies that a contractual sale restriction should not be considered in measuring fair value. It also requires certain qualitative and quantitative disclosures related to equity securities subject to contractual sale restrictions. This authoritative guidance will be effective for us in the first quarter of fiscal 2025, with early adoption permitted. We are evaluating the effect of this new guidance on our consolidated condensed financial statements.
