Accounting Policies [Abstract] |
Consolidation | The condensed consolidated financial statements include the accounts of Lam Research and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Fiscal Period | The Company’s reporting period is a 52/53-week fiscal year. The Company’s current fiscal year will end June 24, 2018 and includes 52 weeks.
Recent Accounting Pronouncements | Recently Adopted In November 2015, the Financial Accounting Standards Board (“FASB”) issued ASU 2015-17, “Balance Sheet Classification of Deferred Taxes.” This ASU amends existing guidance to require that deferred income tax assets and liabilities be classified as non-current in a classified balance sheet, and eliminates the prior guidance which required an entity to separate deferred tax assets and liabilities into a current amount and a non-current amount in a classified balance sheet. The Company adopted this standard prospectively in the first quarter of fiscal year 2018. The implementation resulted in a net reduction of prepaid expense and other current assets of $49.7 million, accrued expense and other current liabilities of $5.3 million, and other long-term liabilities of $39.4 million; and an increase in other assets of $5.0 million in the Company’s Condensed Consolidated Balance Sheet, and had no impact on cash provided by or used in operations for any period presented. In March 2016, the FASB released ASU 2016-9, “Compensation – Stock Compensation.” Key changes in the amendment include:
• | entities will be required to recognize all excess tax benefits or deficiencies as an income tax benefit or expense in the income statement, eliminating additional paid in capital (“APIC”) pools;
• | entities will no longer be required to delay recognition of excess tax benefits until they are realized;
• | entities will be required to classify the excess tax benefits as an operating activity in the statement of cash flows;
• | entities will be allowed to elect an accounting policy to either estimate the number of forfeitures, or account for forfeitures as they occur;
• | entities can withhold up to the maximum individual statutory tax rate without classifying the awards as a liability; and
• | the cash paid to satisfy the statutory income tax withholding obligations shall be classified as a financing activity in the statement of cash flows.
The Company adopted this standard in the first quarter of fiscal year 2018. As a result of the adoption, the Company recorded a $40.1 million cumulative-effect adjustment to retained earnings for the recognition of previously unrecognized excess tax benefits for all years prior to the adoption. As required by the standard update, the amendment was applied prospectively to recognize excess tax benefits or deficiencies in the income statement in the period of occurrence. Accordingly, the provision for income taxes in the three and nine months ended March 25, 2018 included excess tax benefits of $37.1 million and $50.2 million, respectively, that decreased the income tax provision. Additionally, the Company has elected to apply the change in cash flow classification on a prospective basis. The Company has elected to continue to estimate the number of forfeitures expected to occur to determine the amount of compensation cost to be recognized each period. The Company has elected to adopt the effects of the standard update with regard to the income tax withholdings obligations on a prospective basis. The impact of the adoption of the standard applicable to income tax withholdings was not material during the three and nine months ended March 25, 2018. In August 2017, the FASB released ASU 2017-12, “Targeted Improvements to Accounting for Hedging Activities.” The new guidance is intended to: (1) more closely align hedge accounting with an entity’s risk management strategies, (2) simplify the application of hedge accounting by eliminating the requirement to separately measure and report hedge ineffectiveness, and (3) increase transparency around the scope and results of hedging programs. The Company is required to adopt the standard in the first quarter of fiscal year 2020, using a modified-retrospective approach for any cash flow or net investment hedges that exist on the date of adoption. The Company elected to early adopt the standard in the current quarter. The cumulative-effect adjustment to eliminate ineffectiveness is not material to the Company's previously issued Consolidated Financial Statements. The presentation and disclosure have been modified on a prospective basis, as required by the standard update. Updates Not Yet Effective In May 2014, the FASB released Accounting Standards Update (“ASU”) 2014-9, “Revenue from Contracts with Customers,” to supersede nearly all existing revenue recognition guidance under GAAP. The FASB issued subsequent amendments to the initial guidance in August 2015, March 2016, April 2016, May 2016 and December 2016 within ASU 2015-14, ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20, respectively. The core principle of the standard is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The new standard defines a five-step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than required under existing GAAP, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price, and allocating the transaction price to each separate performance obligation. The Company is required to adopt these standards starting in the first quarter of fiscal year 2019 using either of two methods: (1) retrospective to each prior reporting period presented with the option to elect certain practical expedients as defined within the standard; or (2) retrospective with the cumulative effect of initially applying the standard recognized at the date of initial application and providing certain additional disclosures as defined per the standard. The Company currently anticipates adopting this new guidance using the modified retrospective transition method, and is continuing its evaluation of the impact that the new standard will have on its Condensed Consolidated Financial Statements and disclosures, business processes, systems, and controls. While the Company’s evaluation of the impact of the standard on its financial statements with respect to its spare parts and service revenue has not been completed, the Company believes that the timing of revenue recognition for certain of its systems will generally be earlier than under existing revenue recognition guidance. The Company continues to evaluate the impact to its revenues related to its pending adoption of these standards and its preliminary assessments are subject to change. In January 2016, the FASB released ASU 2016-1, “Financial Instruments – Overall – Recognition and Measurement of Financial Assets and Financial Liabilities.” The FASB issued a subsequent amendment to the initial guidance in February 2018 within ASU 2018-03. These amendments change the accounting for and financial statement presentation of equity investments, other than those accounted for under the equity method of accounting or those that result in consolidation of the investee. The amendments provide clarity on the measurement methodology to be used for the required disclosure of fair value of financial instruments measured at amortized cost on the balance sheet and clarifies that an entity should evaluate the need for a valuation allowance on deferred tax assets related to available-for-sale securities in combination with the entity’s other deferred tax assets, among other changes. The Company is required to adopt these standards starting in the first quarter of fiscal year 2019 and does not anticipate that implementation will have a material impact on its Condensed Consolidated Financial Statements. In January 2016, the FASB released ASU 2016-2, “Leases.” The FASB issued a subsequent amendment to the initial guidance in January 2018 within ASU 2018-01. The core principle of the standard requires an entity to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. The amendment offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. The Company is required to adopt these standards starting in the first quarter of fiscal year 2020 using a modified-retrospective approach on the earliest period presented. Early adoption is permitted. The Company is currently in the process of evaluating the impact of adoption on its Condensed Consolidated Financial Statements. In June 2016, the FASB released ASU 2016-13, “Financial Instruments – Credit Losses.” The amendment revises the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in more timely recognition of losses on financial instruments, including but not limited to, available for sale debt securities and accounts receivable. The Company is required to adopt this standard starting in the first quarter of fiscal year 2021 using a modified-retrospective approach. Early adoption is permitted. The Company is currently in the process of evaluating the impact of adoption on its Condensed Consolidated Financial Statements. In August 2016, the FASB released ASU 2016-15, “Statement of Cash Flows – Classification of Certain Cash Receipts and Cash Payments.” The amendment provides and clarifies guidance on the classification of certain cash receipts and cash payments in the statement of cash flows to eliminate diversity in practice. The Company is required to adopt the standard update in the first quarter of fiscal year 2019, with a retrospective transition method required. Early adoption is permitted. The Company is currently in the process of evaluating the impact of adoption on its Condensed Consolidated Financial Statements. In October 2016, the FASB released ASU 2016-16, “Income Tax – Intra-Entity Transfers of Assets Other than Inventory.” This standard update improves the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. Early adoption is permitted. The Company is required to adopt the standard in the first quarter of fiscal year 2019 using a modified-retrospective approach through a cumulative-effect adjustment directly to retained earnings. The Company is currently in the process of evaluating the impact of adoption on its Condensed Consolidated Financial Statements. In November 2016, the FASB released ASU 2016-18, “Statement of Cash Flows – Restricted Cash.” This standard update requires that restricted cash and restricted cash equivalents be included in cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown in the statement of cash flows. The Company is required to adopt this standard in the first quarter of fiscal year 2019, with a retrospective transition method required. Early adoption is permitted. The Company is currently in the process of evaluating the impact of adoption on its Condensed Consolidated Financial Statements. In February 2018, the FASB released ASU 2018-2, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” This standard update addresses a specific consequence of the Tax Cuts and Jobs Act (“U.S tax reform”) and allows a reclassification from accumulated other comprehensive income to retained earnings for the stranded tax effects resulting from U.S. tax reform. Consequently, the update eliminates the stranded tax effects that were created as a result of the historical U.S. federal corporate income tax rate to the newly enacted U.S. federal corporate income tax rate. The Company is required to adopt this standard in the first quarter of fiscal year 2020, with early adoption permitted. The amendments in this update should be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. The Company is currently in the process of evaluating the impact of adoption on its Condensed Consolidated Financial Statements.
Inventories | Inventories are stated at the lower of cost (first-in, first-out method) or net realizable value. System shipments to customers in Japan, for which title does not transfer until customer acceptance, are classified as finished goods inventory and carried at cost until title transfers.
Warranties | The Company provides standard warranties on its systems. The liability amount is based on actual historical warranty spending activity by type of system, customer, and geographic region, modified for any known differences such as the impact of system reliability improvements.
