Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation | Basis of Presentation. For purposes of this report, “KLA,” the “Company,” “we,” “our,” “us,” or similar references mean KLA Corporation, and its majority-owned subsidiaries unless the context requires otherwise. The Condensed Consolidated Financial Statements have been prepared by us pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations. The unaudited interim Condensed Consolidated Financial Statements reflect all adjustments (consisting only of normal, recurring adjustments) necessary for a fair statement of the financial position, results of operations, comprehensive income, stockholders’ equity and cash flows for the periods indicated. These Condensed Consolidated Financial Statements and notes, however, should be read in conjunction with Item 8 “Financial Statements and Supplementary Data” included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2020. The Condensed Consolidated Financial Statements include the accounts of KLA and its majority-owned subsidiaries. All significant intercompany balances and transactions have been eliminated. On February 20, 2019 ("Acquisition Date"), we completed the acquisition of Orbotech Ltd. ("Orbotech") hereinafter referred to as the "Orbotech Acquisition." The results of operations for the three and nine months ended March 31, 2021 are not necessarily indicative of the results that may be expected for any other interim period or for the full fiscal year ending June 30, 2021. Certain reclassifications have been made to the prior year’s Condensed Consolidated Financial Statements to conform to the current year presentation. The reclassifications did not have material effects on the prior year’s Condensed Consolidated Balance Sheets, Statements of Operations, Comprehensive Income and Cash Flows.
Management Estimates | Management Estimates. The preparation of the Condensed Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions in applying our accounting policies that affect the reported amounts of assets and liabilities (and related disclosure of contingent assets and liabilities) at the date of the Condensed Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.
Credit Losses | Credit Losses Cash Equivalents and Marketable Securities. All highly liquid debt instruments with original or remaining maturities of less than three months at the date of purchase are cash equivalents. Marketable securities are generally classified as available-for-sale for use in current operations, if required, and are reported at fair value, with unrealized gains and non-credit related unrealized losses, net of tax, presented as a separate component of stockholders’ equity under the caption “Accumulated other comprehensive income (loss)” (“AOCI”). All realized gains and losses are recorded in earnings in the period of occurrence. The specific identification method is used to determine the realized gains and losses on investments. We regularly review the available-for-sale debt securities in an unrealized loss position, and evaluate the current expected credit loss by considering available information relevant to the collectability of the security, such as historical experience, market data, issuer-specific factors including credit ratings, default and loss rates of the underlying collateral and structure and credit enhancements, current economic conditions and reasonable and supportable forecasts. If we do not expect to recover the entire amortized cost of the security, the amount representing credit losses, defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis of the debt security, is recorded as an allowance for credit losses with an offsetting entry to earnings; and the amount that is not credit-related is recognized in other comprehensive income (loss). If we have the intent to sell the security or it is more likely than not that we will be required to sell the security before recovery of its entire amortized cost basis, we first write off any previously recognized allowance for credit losses with an offsetting entry to the security’s amortized cost basis. If the allowance has been fully written off and fair value is less than amortized cost basis, we write down the amortized cost basis of the security to its fair value with an offsetting entry to net income. There were no credit losses on available-for-sale debt securities recognized for the three and nine months ended March 31, 2021 and 2020. Allowance for Credit Losses. A majority of our accounts receivable are derived from sales to large multinational semiconductor and electronics manufacturers throughout the world. We maintain an allowance for credit losses for expected uncollectable accounts receivable, which is recorded as an offset to accounts receivable and changes in such are classified as selling, general and administrative expense in the Condensed Consolidated Statements of Income. We assess collectability by reviewing accounts receivable on a collective basis where similar risk characteristics exist and on an individual basis when we identify specific customers with known disputes or collectability issues. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. The allowance for credit losses is reviewed on a quarterly basis to assess the adequacy of the allowance. For the three and nine months ended March 31, 2021, our assessment considered the impact of COVID-19 and estimates of expected credit and collectability trends. The credit losses recognized on accounts receivable were not significant for the three and nine months ended March 31, 2021 and 2020. Volatility in market conditions and evolving credit trends are difficult to predict and may cause variability and volatility that may have a material impact on our allowance for credit losses in future periods.
Recent Accounting Pronouncements | Recent Accounting Pronouncements Recently Adopted As explained above, on July 1, 2020, we adopted ASC 326, which was issued by the Financial Accounting Board (“FASB”) in June 2016 as Accounting Standards Update ("ASU") No. 2016-13 Financial Instruments – Credit Losses (ASC 326): Measurement of Credit Losses on Financial Instruments. The ASU replaced previous incurred loss impairment guidance and established a single expected credit losses allowance framework for financial assets carried at amortized cost. It also eliminated the concept of other-than-temporary impairment and requires credit losses related to certain available-for-sale debt securities to be recorded through an allowance for credit losses. We adopted ASC 326 using the modified retrospective method, which requires a cumulative-effect adjustment to the opening balance of retained earnings to be recognized on the date of adoption and, accordingly, recorded a net decrease of $5.5 million to retained earnings as of July 1, 2020. Please see the “Credit Losses” accounting policy in the “Significant Accounting Policies” section above. In August 2018, the FASB issued an accounting standard update which modifies the existing accounting standards for the fair value measurement disclosure. This update eliminates the disclosures of the amount of and reasons for transfers between level 1 and level 2 of the fair value hierarchy, and the policy for the timing of transfers between levels. We adopted this update beginning in the first quarter of our fiscal year ending June 30, 2021 on a retrospective basis and the adoption had no material impact on our Condensed Consolidated Financial Statements. In August 2018, the FASB issued an accounting standard update to amend the disclosure requirements related to defined benefit pension and other post-retirement plans. Some of the changes include adding a disclosure requirement for significant gains and losses related to changes in the benefit obligation for the period and removing the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year. We adopted this update beginning in the first quarter of the fiscal year ending June 30, 2021 on a retrospective basis and the adoption had no material impact on our Condensed Consolidated Financial Statements. In August 2018, the FASB issued an accounting standard update to align the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The guidance clarifies which costs should be capitalized, including the cost to acquire the license and the related implementation costs. We adopted this update beginning in the first quarter of our fiscal year ending June 30, 2021 on a prospective basis, and the adoption had no material impact on our Condensed Consolidated Financial Statements. Updates Not Yet Effective In December 2019, the FASB issued an accounting standard update to simplify the accounting for income taxes in ASC 740, Income Taxes (“ASC 740”). This amendment removes certain exceptions and improves consistent application of accounting principles for certain areas in ASC 740. The update is effective for us beginning in the first quarter of our fiscal year ending June 30, 2022, and early adoption is permitted. We are currently evaluating the impact of this accounting standard update on our Consolidated Financial Statements. In August 2020, the FASB issued an accounting standard update to simplify the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. The standard eliminates beneficial conversion feature and cash conversion models resulting in more convertible instruments being accounted for as a single unit; and modifies the guidance on the computation of earnings per share for convertible instruments and contracts on an entity’s own equity. The update is effective for us in the first quarter of our fiscal year ending June 30, 2023 and can be adopted either on a fully retrospective basis or modified retrospective basis. Early adoption is permitted from our first quarter of fiscal year ending June 30, 2022. We are currently evaluating the impact of this accounting standard update on our Condensed Consolidated Financial Statements.
Fair Value Measurements | Our financial assets and liabilities are measured and recorded at fair value, except for our debt and certain equity investments in privately held companies. Equity investments without a readily available fair value are accounted for using the measurement alternative. The measurement alternative is calculated as cost minus impairment, if any, plus or minus changes resulting from observable price changes. Our non-financial assets, such as goodwill, intangible assets, and land, property and equipment, are assessed for impairment when an event or circumstance indicates that an other-than-temporary decline in value may have occurred.
Fair Value of Financial Instruments | Fair Value of Financial Instruments. We have evaluated the estimated fair value of financial instruments using available market information and valuations as provided by third-party sources. The use of different market assumptions and/or estimation methodologies could have a significant effect on the estimated fair value amounts. The fair value of our cash equivalents, accounts receivable, accounts payable and other current assets and liabilities approximate their carrying amounts due to the relatively short maturity of these items. Fair Value Hierarchy. The authoritative guidance for fair value measurements establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:
Level 1 |  | Valuations based on quoted prices in active markets for identical assets or liabilities that the entity has the ability to access.
Level 2 |  | Valuations based on quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities.
Level 3 |  | Valuations based on inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.
