Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	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. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. The unaudited interim Condensed Consolidated Financial Statements do not include all of the information and footnotes required by GAAP for audited financial statements. The balance sheet as of June 30, 2023 was derived from the Company’s audited Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2023, but does not include all disclosures required by GAAP for audited financial statements. 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, 2023. The Condensed Consolidated Financial Statements include the accounts of KLA and its majority-owned subsidiaries. All significant intercompany balances and transactions have been eliminated. The results of operations for the three months ended September 30, 2023 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, 2024. Management Estimates. The preparation of the Condensed Consolidated Financial Statements in conformity with GAAP 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 dates 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. Significant Accounting Policies. There have been no material changes to our significant accounting policies summarized in Note 1 “Description of Business and Summary of Significant Accounting Policies” to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2023. Recent Accounting Pronouncements Recently Adopted In October 2021, the Financial Accounting Standards Board issued Accounting Standards Update 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The new guidance requires companies to apply revenue guidance to recognize and measure contract assets and contract liabilities from contracts with customers acquired in a business combination at carrying value. Under the prior business combination guidance, such assets and liabilities were recognized by the acquirer at fair value on the acquisition date. We adopted this update beginning in the first quarter of our fiscal year ending June 30, 2024 on a prospective basis. The impact of adopting this update will depend on the magnitude of contract assets and contract liabilities acquired in future acquisitions. Updates Not Yet Effective None.

Revenue from Contract with Customer [Abstract]
REVENUE	REVENUE Contract Balances The following table represents the opening and closing balances of accounts receivable, net, contract assets and contract liabilities as of the indicated dates. As of As of (Dollar amounts in thousands) September 30, 2023 June 30, 2023 $ Change % Change Accounts receivable, net $ 1,630,746 $ 1,753,361 $ (122,615) (7) % Contract assets $ 93,300 $ 117,137 $ (23,837) (20) % Contract liabilities $ 1,264,953 $ 1,245,007 $ 19,946 2 % Our payment terms and conditions vary by contract type, although the terms generally include a requirement of payment of 70% to 90% of total contract consideration within 30 to 60 days of product shipment, with the remainder payable within 30 days of acceptance. The change in contract assets during the three months ended September 30, 2023 was mainly due to $69.8 million of contract assets reclassified to accounts receivable, net as our right to consideration for these contract assets became unconditional, partially offset by $46.5 million of revenue recognized for which the payment is subject to conditions other than passage of time. Contract assets are included in other current assets on our Condensed Consolidated Balance Sheets. The change in contract liabilities during the three months ended September 30, 2023 was mainly due to an increase in the value of products and services billed to customers for which control of the products and services has not transferred to the customers, partially offset by recognition in revenue of $601.1 million that was included in contract liabilities as of June 30, 2023. The change in contract liabilities during the three months ended September 30, 2022 was mainly due to the recognition in revenue of $489.5 million that was included in contract liabilities as of June 30, 2022, partially offset by an increase in the value of products and services billed to customers for which control of the products and services has not transferred to the customers. Contract liabilities are included in current and non-current liabilities on our Condensed Consolidated Balance Sheets. Remaining Performance Obligations As of September 30, 2023, we had $10.85 billion of remaining performance obligations, which represents our obligation to deliver products and services, and primarily consists of sales orders where written customer requests have been received. This amount includes customer deposits of $818.9 million as disclosed in Note 4 “Financial Statement Components” and excludes contract liabilities of $1.26 billion as described above. We expect to recognize approximately 40% to 50% of these performance obligations as revenue beyond the next 12 months, but this estimate is subject to constant change. The supply chain disruptions caused by the pandemic as well as elevated demand levels in recent years have led to customers agreeing to purchase equipment from us with lead times that are longer than our historical experience. More recently, we have seen the macro-driven slowdown has impacted consumers’ semiconductor device demand, causing the semiconductor industry to rebalance its supply chain and inventory levels. In response to this change, some of our customers began adjusting their capacity expansion-focused capital expenditure plans for calendar year 2023. As customers try to balance the evolution of their technological, production or market needs with the timing and content of orders placed with us, there is elevated risk of order modifications, pushouts, or cancellations. In addition, in October 2022, the U.S. government issued regulations that imposed new export licensing requirements for certain U.S. semiconductor and high-performance computing technology (including wafer fab equipment), for the use of such technology for certain end uses in the People’s Republic of China (“China”), and for the provision of support by U.S. Persons to certain advanced integrated circuit (“IC”) fabs located in China. The regulations impose export license requirements effectively on all KLA products and services to customers located in China that fabricate certain advanced logic, NAND and DRAM ICs. KLA is also restricted from providing certain U.S. origin tools, software and technology to certain wafer fab equipment manufacturers located in China, absent an export license. In October 2023, the U.S. government issued additional regulations that go into effect in November 2023. These additional rules are designed to update export controls on advanced computing semiconductors and semiconductor manufacturing equipment, as well as items that support supercomputing applications and end-uses, to arms embargoed countries, including China. They adjust the parameters included in the existing regulations that determine whether an advanced computing chip is restricted and impose new measures to address risks of circumvention of the controls established in October 2022. The regulations are very complex and we are still evaluating these rules and assessing their impact on our business and operations. We are taking appropriate measures to comply with all government regulations, and will continue to apply for export licenses, when required, to avoid disruption to our customers’ operations. While some export licenses have been obtained by us or our customers, there can be no assurance that export licenses applied for by either us or our customers, now or in the future, will be granted.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	3 Months Ended
	Sep. 30, 2023
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	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. See Note 8 “Debt” to our Condensed Consolidated Financial Statements for disclosure of the fair value of our Senior Notes, as defined in that Note. 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. 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. There were no transfers between Level 1, Level 2 and Level 3 fair value measurements during the three months ended September 30, 2023. The types of instruments valued based on quoted market prices in active markets include money market funds, certain U.S. Treasury securities, U.S. Government agency securities and equity securities. Such instruments are generally classified within Level 1 of the fair value hierarchy. The types of instruments valued based on other observable inputs include corporate debt securities, municipal securities and certain U.S. Treasury securities. The market inputs used to value these instruments generally consist of market yields, reported trades and broker/dealer quotes. Such instruments are generally classified within Level 2 of the fair value hierarchy. The principal market in which we execute our foreign currency contracts is the institutional market in an over-the-counter environment with a relatively high level of price transparency. The market participants generally are large financial institutions. Our foreign currency contracts’ valuation inputs are based on quoted prices and quoted pricing intervals from public data sources and do not involve management judgment. These contracts are typically classified within Level 2 of the fair value hierarchy. The fair values of contingent consideration payable, the majority of which were recorded in connection with business combinations, were classified as Level 3 and estimated using significant inputs that were not observable in the market.

(2) Time deposits excluded from fair value measurements. Our investment portfolio includes both corporate and government securities that have a maximum maturity of three years. The longer the duration of these securities, the more susceptible they are to changes in market interest rates and bond yields. As yields increase, those securities with a lower yield-at-cost show a mark-to-market unrealized loss. Most of our unrealized losses are due to changes in market interest rates and bond yields. We believe that we have the ability to realize the full value of all these investments upon maturity. As of September 30, 2023, we had 591 investments in a gross unrealized loss position.

Business Combination and Asset Acquisition [Abstract]
BUSINESS COMBINATIONS AND DISPOSITIONS	BUSINESS COMBINATIONS AND DISPOSITIONS Business Combinations On August 9, 2022, we acquired a privately held company, primarily to secure the supply of materials for existing products, for aggregate purchase consideration of $32.7 million, payable in cash. We allocated the purchase consideration as follows: $30.0 million to identifiable intangible assets, $2.3 million to net tangible assets, $6.5 million to deferred tax liabilities and $6.8 million to goodwill. The goodwill was assigned to the Wafer Inspection and Patterning reporting unit. We have included the financial results of the acquisition in our Condensed Consolidated Financial Statements from the acquisition date, and these results were not material to our Condensed Consolidated Financial Statements. The goodwill recorded as a result of the above acquisition was not deductible for tax purposes. As of September 30, 2023, we had $5.5 million of contingent consideration recorded for the acquisitions completed during our fiscal year ended June 30, 2019, all of which is classified as a current liability on the Condensed Consolidated Balance Sheet. Business Dispositions As of June 30, 2022, we owned approximately 94% of the outstanding equity interest in Orbograph Ltd. (“Orbograph”), a non-core business engaged in the development and marketing of character recognition solutions to banks, financial and other payment processing institutions and healthcare providers. On August 9, 2022, we acquired the non-controlling interest in Orbograph. On August 11, 2022, we sold our entire interest in Orbograph to a portfolio company of a private equity firm for total consideration of $110.0 million and net cash proceeds from the transaction of $75.4 million. We recognized a pre-tax gain from the sale of $29.7 million, which was recorded as part of other expense (income), net. Included in the sale were $26.5 million in tangible assets, $30.5 million in liabilities and $61.2 million in goodwill and intangible assets. For additional details of business combinations and assets held for sale, refer to Note 6 “Business Combinations and Dispositions” to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2023.

GOODWILL AND PURCHASED INTANGIBLE ASSETS	GOODWILL AND PURCHASED INTANGIBLE ASSETS Goodwill Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in business combinations. We have three reportable segments and five operating segments. The operating segments are determined to be the same as reporting units. For additional details, refer to Note 18 “Segment Reporting and Geographic Information” to our Condensed Consolidated Financial Statements.

As of September 30, 2023, there have been no significant events or circumstances affecting the valuation of goodwill subsequent to the annual assessment performed in the third quarter of the fiscal year ended June 30, 2023. There was no goodwill impairment as a result of that assessment.

Impairment indicators primarily include declines in our operating cash flows from the use of these assets. If impairment indicators are present, we are required to perform a recoverability test by comparing the sum of the estimated undiscounted future cash flows attributable to these long-lived assets to their carrying value. As of September 30, 2023, there were no impairment indicators for purchased intangible assets.

A portion of the net proceeds of the 2022 Senior Notes was used to complete a tender offer in July 2022 for $500.0 million of our Senior Notes due November 1, 2024 including associated redemption premiums, accrued interest and other fees and expenses. The transaction resulted in a pre-tax net loss on extinguishment of debt of $13.3 million for the three months ended September 30, 2022. The remainder of the net proceeds were used for share repurchases and for general corporate purposes. Prior to June 2022, the following aggregate principal amounts of senior, unsecured long-term notes were issued in the following periods: $750.0 million in February 2020 (the “2020 Senior Notes”), $1.20 billion in March 2019 (the “2019 Senior Notes”) and $2.50 billion in November 2014 (the “2014 Senior Notes”). These, along with the 2022 Senior Notes, are collectively referred to as the “Senior Notes.” The original discounts on the Senior Notes are being amortized over the life of the debt. Interest is payable as follows: semi-annually on January 15 and July 15 of each year for the 2022 Senior Notes; semi-annually on March 1 and September 1 of each year for the 2020 Senior Notes; semi-annually on March 15 and September 15 of each year for the 2019 Senior Notes; and semi-annually on May 1 and November 1 of each year for the 2014 Senior Notes. The relevant indentures for the Senior Notes (collectively, the “Indenture”) include covenants that limit our ability to grant liens on our facilities and enter into sale and leaseback transactions. In certain circumstances involving a change of control followed by a downgrade of the rating of a series of Senior Notes by at least two of Moody’s Investors Service, S&P Global Ratings and Fitch Inc., unless we have exercised our rights to redeem the Senior Notes of such series, we will be required to make an offer to repurchase all or, at the holder’s option, any part, of each holder’s Senior Notes of that series pursuant to the offer described below (the “Change of Control Offer”). In the Change of Control Offer, we will be required to offer payment in cash equal to 101% of the aggregate principal amount of Senior Notes repurchased plus accrued and unpaid interest, if any, on the Senior Notes repurchased, up to, but not including, the date of repurchase. Based on the trading prices of the Senior Notes on the applicable dates, the fair value of the Senior Notes as of September 30, 2023 and June 30, 2023 was $5.31 billion and $5.69 billion, respectively. While the Senior Notes are recorded at cost, the fair value of the long-term debt was determined based on quoted prices in markets that are not active; accordingly, the long-term debt is categorized as Level 2 for purposes of the fair value measurement hierarchy. As of September 30, 2023, we were in compliance with all of our covenants under the Indenture associated with the Senior Notes. Revolving Credit Facility As of September 30, 2023, we have in place a renegotiated Credit Agreement dated June 8, 2022 (“Credit Agreement”) for an unsecured Revolving Credit Facility (“Revolving Credit Facility”) having a maturity date of June 8, 2027 that allows us to borrow up to $1.50 billion. Subject to the terms of the Credit Agreement, the Revolving Credit Facility may be increased by an amount up to $250.0 million in the aggregate. As of September 30, 2023, we had no outstanding borrowings under the Revolving Credit Facility. We may borrow, repay and reborrow funds under the Revolving Credit Facility until the maturity date, at which time we may exercise two one-year extension options with the consent of the lenders. We may prepay outstanding borrowings under the Revolving Credit Facility at any time without a prepayment penalty. Borrowings under the Revolving Credit Facility can be made as Term Secured Overnight Financing Rate (“SOFR”) Loans or Alternate Base Rate (“ABR”) Loans, at the Company’s option. In the event that Term SOFR is unavailable, any Term SOFR elections will be converted to Daily Simple SOFR, if available. Each Term SOFR Loan will bear interest at a rate per annum equal to the applicable Adjusted Term SOFR rate, which is equal to the applicable Term SOFR rate plus 10 bps that shall not be less than zero, plus a spread ranging from 75 bps to 125 bps , as determined by the Company’s credit ratings at the time. Each ABR Loan will bear interest at a rate per annum equal to the ABR plus a spread ranging from 0 bps to 25 bps , as determined by the Company’s credit ratings at the time. We are also obligated to pay an annual commitment fee on the daily undrawn balance of the Revolving Credit Facility, which ranges from 4.5 bps to 12.5 bps , subject to an adjustment in conjunction with changes to our credit rating. The applicable interest rates and commitment fees are also subject to adjustment based on the Company’s performance against certain environmental sustainability key performance indicators (“KPI”) related to greenhouse gas emissions and renewable electricity usage. Our performance against these KPIs in calendar year 2022 resulted in reductions to the fees associated with our Revolving Credit Facility. As of September 30, 2023, we elected to pay interest on borrowings under the Revolving Credit Facility at the applicable Adjusted Term SOFR rate plus a spread of 97.5 bps and the applicable commitment fee on the daily undrawn balance of the Revolving Credit Facility was 8.5 bps. Under the Credit Agreement, the maximum leverage ratio on a quarterly basis is 3.50 to 1.00, covering the trailing four consecutive fiscal quarters for each fiscal quarter, which may be increased to 4.00 to 1.00 for a period of time in connection with a material acquisition or a series of material acquisitions. As of September 30, 2023, our maximum allowed leverage ratio was 3.50 to 1.00. We were in compliance with all covenants under the Credit Agreement as of September 30, 2023. For additional details, refer to Note 8 “Debt” to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2023.

Leases [Abstract]
LEASES	LEASESWe have operating leases for facilities, vehicles and other equipment. Our facility leases are primarily used for administrative functions, research and development (“R&D”), manufacturing, and storage and distribution. Our finance leases are not material. Our existing leases do not contain significant restrictive provisions or residual value guarantees; however, certain leases contain provisions for the payment of maintenance, real estate taxes or insurance costs by us. Our leases have remaining lease terms ranging from less than one year to 29 years, including periods covered by options to extend the lease when it is reasonably certain that the option will be exercised. Lease expense was $12.4 million and $9.4 million for the three months ended September 30, 2023 and 2022, respectively. Expense related to short-term leases, which are not recorded on the Condensed Consolidated Balance Sheets, was not material for the three months ended September 30, 2023 and 2022. As of September 30, 2023 and June 30, 2023, the weighted-average remaining lease term was 6.6 and 6.7 years, respectively, and the weighted-average discount rate for operating leases was 3.43% and 3.36%, respectively.

Share-Based Payment Arrangement [Abstract]
EQUITY, LONG-TERM INCENTIVE COMPENSATION PLANS AND NON-CONTROLLING INTEREST	EQUITY, LONG-TERM INCENTIVE COMPENSATION PLANS AND NON-CONTROLLING INTEREST Equity Incentive Program As of September 30, 2023, 7.4 million shares remained available for issuance under our 2004 Equity Incentive Plan (the “2004 Plan”). For details of the 2004 Plan refer to Note 10 “Equity, Long-Term Incentive Compensation Plans and Non-Controlling Interest” to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2023. On August 3, 2023, our Board of Directors adopted the KLA Corporation 2023 Incentive Award Plan, which is intended to replace our 2004 Plan. The new plan is subject to approval by our stockholders at the annual meeting of stockholders to be held on November 1, 2023. Equity Incentive Plans - General Information The following table summarizes the combined activity under our equity incentive plans: (In thousands) Available For Grant (1) Balance as of June 30, 2023 7,761 Restricted stock units granted (2) (386) Restricted stock units canceled 27 Balance as of September 30, 2023 7,402 __________________ (1) The number of restricted stock units (“RSU”) reflects the application of the award multiplier of 2.0x to calculate the impact of the award on the shares reserved under the 2004 Plan. (2) Includes RSUs granted to senior management during the three months ended September 30, 2023 with performance-based vesting criteria (in addition to service-based vesting criteria for any of such RSUs that are deemed to have been earned) (“performance-based RSU”). This line item includes all such performance-based RSUs granted during the three months ended September 30, 2023 reported at the maximum possible number of shares that may ultimately be issuable if all applicable performance-based criteria are achieved at their maximum levels and all applicable service-based criteria are fully satisfied (0.2 million shares for the three months ended September 30, 2023 reflects the application of the multiplier described above). The fair value of stock-based awards is measured at the grant date and is recognized as an expense over the employee’s requisite service period. For RSUs granted without “dividend equivalent” rights, fair value is calculated using the closing price of our common stock on the grant date, adjusted to exclude the present value of dividends that are not accrued on those RSUs. The fair value for RSUs granted with “dividend equivalent” rights is determined using the closing price of our common stock on the grant date. The following table shows stock-based compensation expense for the indicated periods: Three Months Ended September 30, (In thousands) 2023 2022 Stock-based compensation expense by: Costs of revenues $ 7,669 $ 5,589 R&D 13,028 8,356 SG&A 28,075 21,037 Total stock-based compensation expense $ 48,772 $ 34,982 Stock-based compensation capitalized as inventory as of September 30, 2023 and June 30, 2023 was $17.5 million and $16.7 million, respectively.

The RSUs granted by us generally vest as follows: (i) with respect to awards with only service-based vesting criteria, over periods ranging from two three The following table shows the weighted-average grant date fair value per unit for the RSUs granted, aggregate grant date fair value of RSUs vested and tax benefits realized by us in connection with vested and released RSUs for the indicated periods : Three Months Ended September 30, (In thousands, except for weighted-average grant date fair value) 2023 2022 Weighted-average grant date fair value per unit $ 501.15 $ 397.40 Grant date fair value of vested RSUs $ 65,524 $ 49,906 Tax benefits realized by us in connection with vested and released RSUs $ 16,054 $ 10,543 As of September 30, 2023, the unrecognized stock-based compensation expense balance related to RSUs was $417.3 million, excluding the impact of estimated forfeitures, and will be recognized over a weighted-average remaining contractual term and an estimated weighted-average amortization period of 1.7 years. The intrinsic value of outstanding RSUs as of September 30, 2023 was $726.8 million. Cash-Based Long-Term Incentive Compensation We have adopted a cash-based long-term incentive (“Cash LTI”) program (“Cash LTI Plan”) for many of our employees as part of our employee compensation program. Executives and non-employee members of the Board of Directors do not participate in the Cash LTI Plan. During both the three months ended September 30, 2023 and 2022, we approved Cash LTI awards of $0.1 million. Cash LTI awards issued to employees under the Cash LTI Plan will vest in three or four equal installments, with one-third or one-fourth of the aggregate amount of the Cash LTI award vesting on each anniversary of the grant date over a three Employee Stock Purchase Plan Our Employee Stock Purchase Plan (“ESPP”) provides that eligible employees may contribute up to 15% of their eligible earnings toward the semi-annual purchase of our common stock. The ESPP is qualified under Section 423 of the Internal Revenue Code. The employee’s purchase price is derived from a formula based on the closing price of the common stock on the first day of the offering period versus the closing price on the date of purchase (or, if not a trading day, on the immediately preceding trading day). The offering period (or length of the look-back period) under the ESPP has a duration of six months, and the purchase price with respect to each offering period, until otherwise amended, is equal to 85% of the lesser of (i) the fair market value of our common stock at the commencement of the applicable six months offering period or (ii) the fair market value of our common stock on the purchase date. We estimate the fair value of purchase rights under the ESPP using a Black-Scholes model. The fair value of each purchase right under the ESPP was estimated on the date of grant using the Black-Scholes model and the straight-line attribution approach with the following weighted-average assumptions: Three Months Ended September 30, 2023 2022 Stock purchase plan: Expected stock price volatility 32.8 % 41.6 % Risk-free interest rate 5.1 % 1.1 % Dividend yield 1.1 % 1.8 % Expected life (in years) 0.5 0.5 There was no cash received from employees for the issuance of shares under the ESPP or shares purchased by employees through the ESPP in the three months ended September 30, 2023 and 2022. The following table shows the tax benefits realized by us in connection with the disqualifying dispositions of shares purchased under the ESPP and the weighted-average fair value per share for the indicated periods: (In thousands, except for weighted-average fair value per share) Three Months Ended September 30, 2023 2022 Tax benefits realized by us in connection with the disqualifying dispositions of shares purchased under the ESPP $ 1,365 $ 562 Weighted-average fair value per share based on Black-Scholes model $ 114.32 $ 73.31 The ESPP shares are replenished annually on the first day of each fiscal year by virtue of an evergreen provision. The provision allows for share replenishment equal to the lesser of 2.0 million shares or the number of shares which we estimate will be required to be issued under the ESPP during the forthcoming fiscal year. As of September 30, 2023, a total of 2.2 million shares were reserved and available for issuance under the ESPP. Quarterly Cash Dividends On September 1, 2023, we paid a quarterly cash dividend of $1.30 per share to stockholders of record as of the close of business on August 15, 2023. The total amount of regular quarterly cash dividends and dividend equivalents paid during the three months ended September 30, 2023 and 2022 was $181.5 million and $188.0 million, respectively. The amount of accrued dividend equivalents payable for regular quarterly cash dividends on unvested RSUs with dividend equivalent rights as of September 30, 2023 and June 30, 2023 was $9.9 million and $12.2 million, respectively. These amounts will be paid upon vesting of the underlying RSUs. Non-Controlling Interest

Equity [Abstract]
STOCK REPURCHASE PROGRAM	STOCK REPURCHASE PROGRAM Our Board of Directors has authorized a program that permits us to repurchase our common stock, including an increase in the authorized repurchase amount of $2.00 billion in the first quarter of fiscal 2024. The stock repurchase program has no expiration date and may be suspended at any time. The intent of the program is, in part, to mitigate the potential dilutive impact related to our equity incentive plans and shares issued in connection with our ESPP as well as to return excess cash to our stockholders. Any and all share repurchase transactions are subject to market conditions and applicable legal requirements. Under the authoritative guidance, share repurchases are recognized as a reduction to retained earnings to the extent available, with any excess recognized as a reduction of capital in excess of par value. In addition, as explained further in Note 13 “Income Taxes,” the Inflation Reduction Act of 2022 (“IRA”) introduced a 1% excise tax imposed on certain stock repurchases by publicly traded companies made after December 31, 2022. The excise tax is recorded as part of the cost basis of treasury stock repurchased after December 31, 2022 and, as such, is included in stockholders’ equity. As of September 30, 2023, an aggregate of $3.45 billion was available for repurchase under the stock repurchase program. Share repurchases for the indicated periods (based on the trade date of the applicable repurchase) were as follows: Three Months Ended September 30, (In thousands) 2023 2022 Number of shares of common stock repurchased 956 257 Total cost of repurchases $ 459,093 $ 89,616

Earnings Per Share [Abstract]
NET INCOME PER SHARE	NET INCOME PER SHARE Basic net income per share is calculated by dividing net income available to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income per share is calculated by using the weighted-average number of common shares outstanding during the period, increased to include the number of additional shares of common stock that would have been outstanding if the shares of common stock underlying our outstanding dilutive RSUs had been issued. The dilutive effect of outstanding RSUs is reflected in diluted net income per share by application of the treasury stock method.

In the normal course of business, we are subject to examination by tax authorities throughout the world. We are subject to U.S. federal income tax examinations for all years beginning from the fiscal year ended June 30, 2018 and are under United States income tax examination for the fiscal years ended June 30, 2018, June 30, 2019 and June 30, 2020. We are subject to state income tax examinations for all years beginning from the fiscal year ended June 30, 2019. We are also subject to examinations in other major foreign jurisdictions, including Singapore and Israel, for all years beginning from the calendar year ended December 31, 2019. It is possible that certain examinations may be concluded in the next 12 months. The timing and resolution of income tax examinations are uncertain. Given the uncertainty around the timing of the resolution of these ongoing examinations, we are unable to estimate the full range of possible adjustments to our unrecognized tax benefits within the next 12 months. Legislative Developments President Biden signed into law the CHIPS and Science Act of 2022 (“CHIPS Act,” where “CHIPS” stands for Creating Helpful Incentives to Produce Semiconductors) on August 9, 2022. The CHIPS Act provides for various incentives and tax credits among other items, including the Advanced Manufacturing Investment Credit (“AMIC”) which equals 25% of qualified investments in an advanced manufacturing facility that is placed in service after December 31, 2022. There was no material impact to our financial statements from the AMIC provision during the three months ended September 30, 2023. President Biden also signed into law the IRA on August 16, 2022. The IRA has several new provisions including a 15% corporate alternative minimum tax (“CAMT”) for certain large corporations that have at least an average of $1.0 billion of adjusted financial statement income over a consecutive three-tax-year period. The CAMT was effective for us in the quarter ended September 30, 2023 and we are not expecting to have any tax impact from the CAMT for the fiscal year ended June 30, 2024. The IRA also introduced a 1% excise tax imposed on certain stock repurchases by publicly traded companies made after December 31, 2022. We began recording the excise tax as part of the cost basis of treasury stock repurchased after December 31, 2022. Other than the AMIC, the CAMT and the excise tax imposed on certain stock repurchases as mentioned above, we are currently evaluating the applicability and impact of the other provisions in the IRA and the CHIPS Act on our Condensed Consolidated Financial Statements including our future cash flows.

LITIGATION AND OTHER LEGAL MATTERS	LITIGATION AND OTHER LEGAL MATTERSWe are named from time to time as a party to lawsuits and other types of legal proceedings and claims in the normal course of our business. Actions filed against us include commercial, intellectual property (“IP”), customer, and labor and employment related claims, including complaints of alleged wrongful termination and potential class action lawsuits regarding alleged violations of federal and state wage and hour and other laws. In general, legal proceedings and claims, regardless of their merit, and associated internal investigations (especially those relating to IP or confidential information disputes) are often expensive to prosecute, defend or conduct, and may divert management’s attention and other Company resources. Moreover, the results of legal proceedings are difficult to predict, and the costs incurred in litigation can be substantial, regardless of outcome. We believe the amounts provided in our Condensed Consolidated Financial Statements are adequate in light of the probable and estimated liabilities. However, because such matters are subject to many uncertainties and the ultimate outcomes are not predictable, there can be no assurances that the actual amounts required to satisfy alleged liabilities from the matters described above will not exceed the amounts reflected in our Condensed Consolidated Financial Statements or will not have a material adverse effect on our results of operations, financial condition or cash flows.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Factoring. We have factoring agreements with financial institutions to sell certain of our trade receivables and promissory notes from customers without recourse. We do not believe we are at risk for any material losses as a result of these agreements. In addition, we periodically sell certain letters of credit (“LC”), without recourse, received from customers in payment for goods and services. The following table shows total receivables sold under factoring agreements and proceeds from sales of LC for the indicated periods: Three Months Ended September 30, (In thousands) 2023 2022 Receivables sold under factoring agreements $ 45,607 $ 104,247 Proceeds from sales of LC $ — $ 24,651 Factoring and LC fees for the sale of certain trade receivables were recorded in other expense (income), net and were not material for the periods presented. Purchase Commitments. We maintain commitments to purchase inventory from our suppliers as well as goods, services and other assets in the ordinary course of business. Our liability under these purchase commitments is generally restricted to a forecasted time-horizon as mutually agreed between the parties. This forecasted time-horizon can vary among different suppliers. Our estimate of our significant purchase commitments primarily for material, services, supplies and asset purchases is approximately $2.3 billion as of September 30, 2023, a majority of which are due within the next 12 months. Actual expenditures will vary based upon the volume of the transactions and length of contractual service provided. In addition, the amounts paid under these arrangements may be less in the event that the arrangements are renegotiated or canceled. Certain agreements provide for potential cancellation penalties. Cash LTI Plan. As of September 30, 2023, we have committed $168.8 million for future payment obligations under our Cash LTI Plan. The calculation of compensation expense related to the Cash LTI Plan includes estimated forfeiture rate assumptions. Cash LTI awards issued to employees under the Cash LTI Plan vest in three or four equal installments, with one-third or one-fourth of the aggregate amount of the Cash LTI award vesting on each anniversary of the grant date over a three Guarantees and Contingencies. We maintain guarantee arrangements available through various financial institutions for up to $74.2 million, of which $41.2 million had been issued as of September 30, 2023, primarily to fund guarantees to customs authorities for value-added tax and other operating requirements of our consolidated subsidiaries in Europe, Israel and Asia. Indemnification Obligations. Subject to certain limitations, we are obligated to indemnify our current and former directors, officers and employees with respect to certain litigation matters and investigations that arise in connection with their service to us. These obligations arise under the terms of our certificate of incorporation, our bylaws, applicable contracts, and Delaware and California law. The obligation to indemnify generally means that we are required to pay or reimburse the individuals’ reasonable legal expenses and possibly damages and other liabilities incurred by several of our current and former directors, officers and employees in connection with these matters. For example, we have paid or reimbursed legal expenses incurred in connection with the investigation of our historical stock option practices and the related litigation and government inquiries. Although the maximum potential amount of future payments we could be required to make under the indemnification obligations generally described in this paragraph is theoretically unlimited, we believe the fair value of this liability, to the extent estimable, is appropriately considered within the reserve we have established for currently pending legal proceedings. We are a party to a variety of agreements pursuant to which we may be obligated to indemnify the other party with respect to certain matters. Typically, these obligations arise in connection with contracts and license agreements or the sale of assets, under which we customarily agree to hold the other party harmless against losses arising therefrom, or provide customers with other remedies to protect against bodily injury or damage to personal property caused by our products, non-compliance with our product performance specifications, infringement by our products of third-party IP rights and a breach of warranties, representations and covenants related to matters such as title to assets sold, validity of certain IP rights, non-infringement of third-party rights, and certain income tax-related matters. In each of these circumstances, payment by us is typically subject to the other party making a claim to and cooperating with us pursuant to the procedures specified in the particular contract. This usually allows us to challenge the other party’s claims or, in case of breach of IP representations or covenants, to control the defense or settlement of any third-party claims brought against the other party. Further, our obligations under these agreements may be limited in terms of amounts, activity (typically at our option to replace or correct the products or terminate the agreement with a refund to the other party), and duration. In some instances, we may have recourse against third parties and/or insurance covering certain payments made by us. In addition, we may, in limited circumstances, enter into agreements that contain customer-specific commitments on pricing, tool reliability, spare parts stocking levels, response time and other commitments. Furthermore, we may give these customers limited audit or inspection rights to enable them to confirm that we are complying with these commitments. If a customer elects to exercise its audit or inspection rights, we may be required to expend significant resources to support the audit or inspection, as well as to defend or settle any dispute with a customer that could potentially arise out of such audit or inspection. To date, we have made no significant accruals in our Condensed Consolidated Financial Statements for this contingency. While we have not in the past incurred significant expenses for resolving disputes regarding these types of commitments, we cannot make any assurance that we will not incur any such liabilities in the future. It is not possible to predict the maximum potential amount of future payments under these or similar agreements due to the conditional nature of our obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments made by us under these agreements have not had a material effect on our business, financial condition, results of operations or cash flows.

DERIVATIVE INSTRUMENTS AND HEDG

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	3 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES The authoritative guidance requires companies to recognize all derivative instruments, including foreign exchange contracts and rate lock agreements (collectively “derivatives”), as either assets or liabilities at fair value on the Condensed Consolidated Balance Sheets. In accordance with the accounting guidance, we designate foreign currency forward transactions and options contracts and interest rate forward transactions as cash flow hedges. In accordance with the accounting guidance, we also designate certain foreign currency exchange contracts as net investment hedge transactions intended to mitigate the variability of the value of certain investments in foreign subsidiaries. Our foreign subsidiaries operate and sell our products in various global markets. As a result, we are exposed to risks relating to changes in foreign currency exchange rates. We utilize foreign exchange contracts to hedge against future movements in foreign currency exchange rates that affect certain existing and forecasted foreign currency denominated sales and purchase transactions, such as the Japanese yen, the euro, the pound sterling and the new Israeli shekel. We routinely hedge our exposures to certain foreign currencies with various financial institutions in an effort to minimize the impact of certain currency exchange rate fluctuations. These foreign exchange contracts, designated as cash flow hedges, generally have maturities of less than 18 months. Cash flow hedges are evaluated for effectiveness monthly, based on changes in total fair value of the derivatives. If a financial counterparty to any of our hedging arrangements experiences financial difficulties or is otherwise unable to honor the terms of the foreign currency hedge, we may experience material losses. Since fiscal 2015, we have entered into four sets of forward contracts to hedge the benchmark interest rate on portions of our Senior Notes prior to issuance (“Rate Lock Agreements”). Upon issuance of the associated debt, the Rate Lock Agreements were settled and their fair values were recorded within AOCI. The resulting gains and losses from these transactions are amortized to interest expense over the lives of the associated debt. We recognized net gains of $0.9 million in the three months ended September 30, 2023, for the amortization of the net of the Rate Lock Agreements that had been recognized in AOCI, which decreased the interest expense on a net basis. We recognized a net gain of $0.9 million in the three months ended September 30, 2022, for the amortization of the net of the Rate Lock Agreements that had been recognized in AOCI, which increased the interest expense on a net basis. As of September 30, 2023, the aggregate unamortized portion of the fair value of the forward contracts for the Rate Lock Agreements was a $50.1 million net gain. For derivatives that are designated and qualify as cash flow hedges, the effective portion of the gains or losses is reported in AOCI and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. For derivative contracts executed after adopting the new accounting guidance in fiscal 2019, the election to include time value for the assessment of effectiveness is made on all forward contracts designated as cash flow hedges. The change in fair value of the derivative is recorded in AOCI until the hedged item is recognized in earnings. The assessment of effectiveness of options contracts designated as cash flow hedges exclude time value. The initial value of the component excluded from the assessment of effectiveness is recognized in earnings over the life of the derivative contract. Any differences between changes in the fair value of the excluded components and the amounts recognized in earnings are recorded in AOCI. For derivatives that are designated and qualify as a net investment hedge in a foreign operation and that meet the effectiveness requirements, the net gains or losses attributable to changes in spot exchange rates are recorded in cumulative translation within AOCI. The remainder of the change in value of such instruments is recorded in earnings using the mark-to-market approach. Recognition in earnings of amounts previously recorded in cumulative translation is limited to circumstances such as complete or substantially complete liquidation or sale of the net investment in the hedged foreign operations. For derivatives that are not designated as hedges, gains and losses are recognized in other expense (income), net. We use foreign exchange contracts to hedge certain foreign currency denominated assets or liabilities.

Segment Reporting [Abstract]
SEGMENT REPORTING AND GEOGRAPHIC INFORMATION	SEGMENT REPORTING AND GEOGRAPHIC INFORMATION Accounting Standards Codification 280, Segment Reporting, establishes standards for reporting information about operating segments. Operating segments are defined as components of an enterprise about which separate financial information is evaluated regularly by the chief operating decision maker (“CODM”) in deciding how to allocate resources and in assessing performance. Our CODM is our Chief Executive Officer. We have three reportable segments: Semiconductor Process Control; Specialty Semiconductor Process; and PCB, Display and Component Inspection. The reportable segments are determined based on several factors including, but not limited to, customer base, homogeneity of products, technology, delivery channels and similar economic characteristics. Semiconductor Process Control The Semiconductor Process Control segment offers a comprehensive portfolio of inspection, metrology and data analytics products, and related services, which helps IC manufacturers achieve target yield throughout the entire semiconductor fabrication process, from R&D to final volume production. Our differentiated products and services are designed to provide comprehensive solutions that help our customers accelerate development and production ramp cycles, achieve higher and more stable semiconductor die yields and improve their overall profitability. This reportable segment is comprised of two operating segments, Wafer Inspection and Patterning and GSS. Specialty Semiconductor Process The Specialty Semiconductor Process segment develops and sells advanced vacuum deposition and etching process tools, which are used by a broad range of specialty semiconductor customers, including manufacturers of microelectromechanical systems (“MEMS”), radio frequency (“RF”) communication chips and power semiconductors for automotive and industrial applications. This reportable segment is comprised of one operating segment. PCB, Display and Component Inspection The PCB, Display and Component Inspection segment enables electronic device manufacturers to inspect, test and measure PCBs, flat panel displays and ICs to verify their quality, pattern the desired electronic circuitry on the relevant substrate and perform three-dimensional shaping of metalized circuits on multiple surfaces. This reportable segment is comprised of two operating segments, PCB and Display and Component Inspection. The CODM assesses the performance of each operating segment and allocates resources to those segments based on total revenues and segment gross profit and does not evaluate the segments using discrete asset information. Segment gross profit excludes corporate allocations and effects of changes in foreign currency exchange rates, amortization of intangible assets, amortization of inventory fair value adjustments, and transaction costs associated with our acquisitions related to costs of revenues. The following is a summary of results for each of our three reportable segments for the indicated periods: Three Months Ended September 30, (In thousands) 2023 2022 Semiconductor Process Control: Revenues $ 2,135,478 $ 2,397,759 Segment gross profit 1,386,529 1,576,982 Specialty Semiconductor Process: Revenues 126,719 127,867 Segment gross profit 69,301 67,040 PCB, Display and Component Inspection: Revenues 136,043 200,745 Segment gross profit 39,820 85,674 Totals: Revenues for reportable segments $ 2,398,240 $ 2,726,371 Segment gross profit $ 1,495,650 $ 1,729,696 The following table reconciles total reportable segment revenues to total revenues for the indicated periods: Three Months Ended September 30, (In thousands) 2023 2022 Total revenues for reportable segments $ 2,398,240 $ 2,726,371 Corporate allocations and effects of changes in foreign currency exchange rates (1,284) (1,947) Total revenues $ 2,396,956 $ 2,724,424 The following table reconciles total segment gross profit to income before income taxes for the indicated periods: Three Months Ended September 30, (In thousands) 2023 2022 Total segment gross profit $ 1,495,650 $ 1,729,696 Acquisition-related charges, corporate allocations and effects of changes in foreign currency exchange rates (1) 45,585 46,498 R&D 311,214 318,515 SG&A 239,645 253,980 Interest expense 74,234 74,395 Loss on extinguishment of debt — 13,286 Other expense (income), net (26,739) (47,006) Income before income taxes $ 851,711 $ 1,070,028 __________________ (1) Acquisition-related charges primarily include amortization of intangible assets and other acquisition-related costs classified or presented as part of costs of revenues. Our significant operations outside the United States include manufacturing facilities in China, Germany, Israel and Singapore and sales, marketing and service offices in Japan, the rest of the Asia Pacific region and Europe. For geographical revenue reporting, revenues are attributed to the geographic location in which the customer is located. Long-lived assets consist of land, property and equipment, net, and are attributed to the geographic region in which they are located.

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. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. The unaudited interim Condensed Consolidated Financial Statements do not include all of the information and footnotes required by GAAP for audited financial statements. The balance sheet as of June 30, 2023 was derived from the Company’s audited Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2023, but does not include all disclosures required by GAAP for audited financial statements. 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, 2023. The Condensed Consolidated Financial Statements include the accounts of KLA and its majority-owned subsidiaries. All significant intercompany balances and transactions have been eliminated. The results of operations for the three months ended September 30, 2023 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, 2024.
Management Estimates	Management Estimates. The preparation of the Condensed Consolidated Financial Statements in conformity with GAAP 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 dates 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.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted In October 2021, the Financial Accounting Standards Board issued Accounting Standards Update 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The new guidance requires companies to apply revenue guidance to recognize and measure contract assets and contract liabilities from contracts with customers acquired in a business combination at carrying value. Under the prior business combination guidance, such assets and liabilities were recognized by the acquirer at fair value on the acquisition date. We adopted this update beginning in the first quarter of our fiscal year ending June 30, 2024 on a prospective basis. The impact of adopting this update will depend on the magnitude of contract assets and contract liabilities acquired in future acquisitions. Updates Not Yet Effective None.
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. See Note 8 “Debt” to our Condensed Consolidated Financial Statements for disclosure of the fair value of our Senior Notes, as defined in that Note. 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. There were no transfers between Level 1, Level 2 and Level 3 fair value measurements during the three months ended September 30, 2023. The types of instruments valued based on quoted market prices in active markets include money market funds, certain U.S. Treasury securities, U.S. Government agency securities and equity securities. Such instruments are generally classified within Level 1 of the fair value hierarchy. The types of instruments valued based on other observable inputs include corporate debt securities, municipal securities and certain U.S. Treasury securities. The market inputs used to value these instruments generally consist of market yields, reported trades and broker/dealer quotes. Such instruments are generally classified within Level 2 of the fair value hierarchy. The principal market in which we execute our foreign currency contracts is the institutional market in an over-the-counter environment with a relatively high level of price transparency. The market participants generally are large financial institutions. Our foreign currency contracts’ valuation inputs are based on quoted prices and quoted pricing intervals from public data sources and do not involve management judgment. These contracts are typically classified within Level 2 of the fair value hierarchy.
