Notes to Condensed Consolidated Financial Statements

(Unaudited)

NOTE 1 – BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of presentation The condensed consolidated financial statements have been prepared by KLA-Tencor Corporation (“KLA-Tencor” or the “Company”) pursuant to the rules and regulations of the 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. In the opinion of management, the unaudited interim financial statements reflect all adjustments (consisting only of normal, recurring adjustments) necessary for a fair presentation of the financial position, results of operations and cash flows for the periods indicated. These financial statements and notes, however, should be read in conjunction with the Item 8, “Financial Statements and Supplementary Data” included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2002, filed with the SEC on September 20, 2002.

The results of operations for the three and nine months ended March 31, 2003 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, 2003.

Fair Value of Financial Instruments KLA-Tencor has evaluated the estimated fair value of financial instruments using available market information and valuation methodologies. 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 KLA-Tencor’s cash, cash equivalents, accounts receivable, accounts payable and other current liabilities approximates the carrying amount due to the relatively short maturity of these items.

Marketable Securities Short-term marketable securities include debt and equity securities acquired with maturities exceeding three months but less than one year from the date of acquisition. Non-current marketable securities include debt securities acquired with maturities exceeding one year from the date of acquisition. While KLA-Tencor’s intent is to hold debt securities to maturity, KLA-Tencor has classified all debt securities as available-for-sale, as the sale of such securities may be required prior to maturity to implement management strategies. Such securities are reported at fair value determined based on quoted market prices at the reporting date for those instruments, with unrealized gains and losses excluded from earnings and included in “Accumulated other comprehensive income,” net of applicable taxes, until realized. KLA-Tencor has classified some equity securities that have readily determinable fair values in a similar manner. The cost of securities sold is based on the specific identification method. Realized gains or losses and declines in value, if any, judged to be other than temporary are reported in “Interest income and other, net” in the Condensed Consolidated Statements of Operations. Certain equity securities have been classified as trading securities. These trading securities are reported at fair value determined based on quoted market prices at the reporting date for those instruments, with unrealized gains or losses included in earnings for the applicable period. The net amount of such gains and losses for the three months and nine months ended March 31, 2003 were not material. As of March 31, 2003, the fair value of the trading securities was $9 million.

Intangible Assets Purchased technology, patents, trademarks, other intangible assets and goodwill are presented at cost, net of accumulated amortization. Effective July 1, 2001, KLA-Tencor replaced ratable amortization of goodwill with periodic testing of goodwill for impairment in accordance with the provision of Statement of Financial Accounting Standard No. 142, “Goodwill and Intangible Assets.” Intangible assets other than goodwill are amortized over their estimated useful lives using the straight-line method.

Page 6

Impairment of Long-Lived Assets KLA-Tencor evaluates the carrying value of its long-lived assets whenever events or changes in circumstances indicate that the carrying value of the asset may be impaired in accordance with the provisions of Statement of Financial Accounting Standard No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets.” An impairment loss is recognized when estimated future cash flows expected to result from the use of the asset including disposition is less than the carrying value of the asset.

Concentration of Credit Risk Financial instruments, which potentially subject KLA-Tencor to credit risk, consist principally of investments, accounts receivable and derivative financial instruments used in hedging activities.

Investments are maintained with high-quality institutions, and the composition and maturities of investments are regularly monitored by management. Generally, these securities are traded in a highly liquid market, may be redeemed upon demand and bear minimal risk. KLA-Tencor, by policy, limits the amount of credit exposure to any one financial institution or commercial issuer. KLA-Tencor has not experienced any material losses on its investments.

A majority of KLA-Tencor’s trade receivables are derived from sales to large multinational semiconductor manufacturers throughout the world. Concentration of credit risk with respect to trade receivables is considered to be limited due to its customer base and the diversity of its geographic sales areas. KLA-Tencor performs ongoing credit evaluations of its customers’ financial condition. KLA-Tencor maintains a reserve for potential credit losses based upon expected collectibility of all accounts receivable.

KLA-Tencor is exposed to credit loss in the event of nonperformance by counterparties on the foreign exchange contracts used in hedging activities. KLA-Tencor does not anticipate nonperformance by these counterparties.

Warranty KLA-Tencor provides standard warranty coverage on its systems for twelve months, providing labor and parts necessary to repair the systems during the warranty period. KLA-Tencor accounts for the estimated warranty cost as a charge to cost of sales when revenue is recognized. The estimated warranty cost is based on historical product performance and field expenses. Utilizing actual service records, KLA-Tencor calculates the average service hours and parts expense per system and applies the actual labor and overhead rates to determine the estimated warranty charge. KLA-Tencor updates these estimated charges every quarter. The actual product performance and/or field expense profiles may differ, and in those cases KLA-Tencor adjusts warranty accruals accordingly (see Note 6 “Commitments and Contingencies” in Item 1 of this report).

Revenue Recognition In December 1999, the SEC issued Staff Accounting Bulletin (“SAB”) No. 101, “Revenue Recognition in Financial Statements.” The SEC Staff addressed several issues in SAB 101, including the timing of revenue recognition for sales that involve contractual customer acceptance provisions and installation of the product if these events occur after shipment and transfer of title. KLA-Tencor implemented the provisions of SAB 101 in the fourth fiscal quarter of 2001, retroactive to July 1, 2000. Prior to adoption of SAB 101, KLA-Tencor’s general policy was to recognize revenue on shipment.

KLA-Tencor derives revenue from four sources – system sales, spare part sales, service contracts and software license fees. System sales include hardware and software that is incidental to the product. Prior to the implementation of SAB 101, system revenue was generally recognized upon shipment. Effective July 1, 2000, KLA-Tencor changed its method of accounting for system sales to generally recognize revenue upon a positive affirmation by the customer that the system has been installed and is operating according to predetermined specifications. In certain limited cases, KLA-Tencor may deviate from the need for a written acceptance by the customer, as follows:

Page 7

        o When system sales to independent distributors have no installation, contain no acceptance agreement, and 100% payment is due upon shipment, revenue is recognized on shipment;

        o When the system requires no integration and installation is inconsequential, revenue is recognized on shipment. In these cases KLA-Tencor is required to perform the installation but KLA-Tencor considers installation not essential to the functionality of the equipment, and there are no additional tests required to be performed on-site. In addition, third party distributors and customers regularly complete the installation of these tools;

        o When the customer fab has already accepted the same tool, with the same specifications on the same process, for the same application, and it can be objectively demonstrated that it meets all of the required acceptance criteria upon shipment, a portion of revenue can be recognized at the time of shipment. Revenue recognized upon shipment is exclusive of the amount allocable to the installation element. Revenue attributable to the installation element is the higher of the payment amount due upon acceptance or the fair value of installation;

        o When the system is performing in production and meets all published and contractually agreed specifications, but the customer withholds signature on our acceptance document due to warranty or other issues unrelated to product performance;

        o When the system is damaged during transit, revenue is recognized upon receipt of cash payment from the customer.

Total revenue recognized under conditions where KLA-Tencor deviates from the need for a written acceptance by the customer were less than 3.0% of total revenue for the three months and nine months ended March 31, 2003, respectively, compared with 2.5% of total revenue for each of the three and nine months ended March 31, 2002, respectively.

In accordance with SAB 101, KLA-Tencor also allows for multiple element revenue arrangement in cases where certain elements of a sales contract are not delivered and accepted at the same time. In such cases, KLA-Tencor defers the fair value of the unaccepted element until that element is delivered to and accepted by the customer. To be considered a separate element, the product or service in question must represent a separate earnings process, and is not essential to the functionality of the delivered and accepted portion of the same sales contract. If the unaccepted element is essential to the functionality of the delivered and accepted portion, the whole amount of the sales contract is deferred until all elements are accepted.

Spare parts revenue is recognized when the product has been shipped, risk of loss has passed to the customer and collection of the resulting receivable is probable.

Service and maintenance revenue is recognized ratably over the term of the maintenance contract. If maintenance is included in an arrangement, which includes a software license agreement, amounts related to maintenance are allocated based on vendor specific objective evidence. Non-standard warranty includes services incremental to the standard 40-hour per week coverage for twelve months. Non-standard warranty is deferred as unearned revenue and is recognized ratably as revenue when the applicable warranty term period commences. Consulting and training revenue is recognized when the related services are performed.

Page 8

Revenue from software license fees is typically recognized upon shipment if collection of the resulting receivable is probable, the fee is fixed or determinable, and vendor-specific objective evidence exists to allocate a portion of the total fee to any undelivered elements of the arrangement. Such undelivered elements in these arrangements typically consist of services and/or upgrades. If vendor-specific objective evidence does not exist for the undelivered elements of the arrangement, all revenue is deferred until such evidence does exist, or until all elements are delivered, whichever is earlier. In instances where an arrangement to deliver software requires significant modification or customization, license fees are recognized under the percentage of completion method of contract accounting. Allowances are established for potential product returns and credit losses. To date, revenue from license fees have been less than 10% of total revenue.

As a result of implementing SAB 101, KLA-Tencor changed its method of accounting for revenue recognition. This change resulted in cumulative deferred revenue of $660.9 million as of July 1, 2000, which was recorded as a non-cash charge of $306.4 million (after reduction for product and warranty costs of $207 million and income taxes of $147.5 million). The deferred profit balance as of March 31, 2003 was $180 million and equals the amount of system revenue that was invoiced and due on shipment but deferred under SAB 101 less applicable product and warranty costs. KLA-Tencor also defers the fair value of non-standard warranty bundled with equipment sales as unearned revenue. The unearned revenue balance as of March 31, 2003 and June 30, 2002 was $50 million and $55 million, respectively.

Strategic Development Agreements Gross engineering, research and development expenses were partially offset by external funding received under certain strategic development programs conducted with several of our customers and government grants. The Company received external funding of $3 million and $13 million for the three and nine months ended March 31, 2003, respectively, compared to $5 million and $10 million for the three and nine months ended March 31, 2002, respectively.

Earnings Per Share Basic earnings per share (“EPS”) is calculated by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated by using the weighted average number of common shares outstanding during the period and gives effect to all dilutive potential common shares outstanding during the period. The reconciling difference between the computation of basic and diluted earnings per share for all periods presented is the inclusion of the dilutive effect of stock options issued to employees under employee stock option plans.

During the three months and nine months ended March 31, 2003, options to purchase approximately 6,746,728 shares and 6,181,089 shares, respectively, at prices ranging from $35.88 to $68.00, were not included in the computation of diluted EPS because the exercise price was greater than the average market price of common shares. During the three months and nine months ended March 31, 2002, options to purchase approximately 19,505 shares and 264,278 shares, respectively, at prices ranging from $56.31 to $68.00 were not included in the computation of diluted EPS because the exercise price was greater than the average market price of common shares.

Accounting for Stock-Based Compensation Plans KLA-Tencor accounts for its employee stock option and employee stock purchase plans under the recognition and measurement principles of APB Opinion No. 25, Accounting for Stock Issued to Employees, and related Interpretations. No stock- based employee compensation is reflected in net income, as all options granted under those plans had an exercise price equal to the market value of the underlying common stock on the date of grant. In December 2002, FASB issued Statement of Financial Accounting Standards No. 148 (SFAS 148), “Accounting for Stock-Based Compensation Transition and Disclosure”. This Statement amends SFAS 123, to provide alternative methods of transition for an entity that voluntarily changes to the fair value based method of accounting for stock-based employee compensation. It also amends the disclosure provisions of that Statement to require prominent disclosure about the effects on reported net income of an entity’s accounting policy decisions with respect to stock-based employee compensation. Finally, this Statement amends APB Opinion No. 28, Interim Financial Reporting, to require disclosure about those effects in interim financial information. Since KLA-Tencor continues to account for stock-based compensation according to APB 25, its adoption of SFAS No. 148 required the Company to provide prominent disclosures about the effects of SFAS 123 on reported income and required the Company to disclose these affects in the interim financial statements as well.

Page 9

The following table illustrates the effect on net income and earnings per share if the Company had applied the fair value recognition provisions of FASB Statement No. 123 (“SFAS 123”), Accounting for Stock-Based Compensation and Statement of Financial Accounting Standards No. 148 (SFAS 148), “Accounting for Stock-Based Compensation Transition and Disclosure”, to stock-based employee compensation:

SFAS No. 123 requires the use of option pricing models that were not developed for use in valuing employee stock options. The Black-Scholes option-pricing model was developed for use in estimating the fair value of short-lived exchange traded options that have no vesting restrictions and are fully transferable. In addition, option-pricing models require the input of highly subjective assumptions, including the option’s expected life and the price volatility of the underlying stock. Because the company’s employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in the opinion of management, the existing models do not necessarily provide a reliable single measure of the fair value of employee stock options.

Reclassifications Certain prior year balances have been reclassified to conform to the current financial statement presentation. These reclassifications had no impact on previously reported results of operations or stockholders’ equity.

Recent Accounting Pronouncements In July 2002, KLA-Tencor adopted Statement No. 143 (“SFAS 143”), “Accounting for Obligations Associated with the Retirement of Long-Lived Assets”. SFAS 143 establishes accounting standards for the recognition and measurement of an asset retirement obligation and its associated asset retirement cost. It also provides guidance for legal obligations associated with the retirement of tangible long-lived assets. Adoption of SFAS 143 did not have a material impact on the Company’s consolidated financial statements

Page 10

In June 2002, the FASB issued Statement No. 146 (“SFAS 146”), “Accounting for Costs Associated with Exit or Disposal Activities.” SFAS 146 addresses financial accounting and reporting for costs associated with exit or disposal activities, and nullifies Emerging Issues Task Force (“EITF”) Issue No. 94-3, Liabilities Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring). This Statement requires that a liability for costs associated with an exit or disposal activity be recognized and measured initially at fair value only when the liability is incurred. SFAS 146 is effective for KLA-Tencor for exit or disposal activities that are initiated after December 31, 2002. The standard will in certain circumstances change the timing of recognition of restructuring costs.

In November 2002, the EITF reached a consensus on Issue No. 00-21, “Accounting for Revenue Arrangements with Multiple Deliverables.” This issue addresses determination of whether an arrangement involving more than one deliverable contains more than one unit of accounting and how arrangement consideration should be measured and allocated to the separate units of accounting. EITF Issue No. 00-21 will be effective for revenue arrangements entered into in fiscal periods beginning after June 15, 2003 or the Company may elect to report the change in accounting as a cumulative-effect adjustment. The Company believes that the adoption of this standard will have no material impact on its consolidated financial statements.

In January 2003, the FASB issued FASB Interpretation No. 46 (“FIN 46”), “Consolidation of Variable Interest Entities”, an Interpretation of ARB No. 51.  FIN 46 requires certain variable interest entities to be consolidated by the primary beneficiary of the entity if the equity investors in the entity do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. FIN 46 is effective immediately for all new variable interest entities created or acquired after January 31, 2003. For variable interest entities created or acquired prior to February 1, 2003, the provisions of FIN 46 must be applied for the first interim or annual period beginning after June 15, 2003.  The Company believes that the adoption of this standard will have no material impact on the consolidated financial statements.

NOTE 2 – INVENTORIES

Inventories are stated at the lower of standard cost (which approximates the first-in, first-out basis) or market. The components of inventories are as follows:

Page 11

NOTE 3 – STOCK REPURCHASE PROGRAM

The Company has adopted a plan to repurchase shares of its Common Stock on the open market for the purpose of partially offsetting dilution created by employee stock options and stock purchase plans. On October 10, 2002, the Board of Directors authorized the repurchase of an additional 5 million shares under the plan. During the nine months ended March 31, 2003 and 2002, the Company repurchased 1,895,000 and 3,250,000 shares of its Common Stock at a cost of approximately $63 million and $118 million, respectively.

NOTE 4 – COMPREHENSIVE INCOME

The components of comprehensive income, net of tax, are as follows:

NOTE 5 – NONRECURRING ACQUISITION, RESTRUCTURING AND OTHER COSTS

Restructuring and Other Costs

During the three months ended September 30, 2002, KLA-Tencor restructured certain of its operations and facilities to accommodate the planned occupancy of its Livermore campus and to streamline operations due to the industry downturn. Restructuring costs were classified into two main categories: facilities and other charges of $4.6 million and severance and benefits of $1.1 million. As part of the facilities consolidation, KLA-Tencor is exiting several of its leased buildings and has included the remaining net book value of the related leasehold improvements as well as the future lease payments, net of anticipated sublease revenue, in the charge. Severance and benefits include involuntary termination of approximately 70 personnel from manufacturing, engineering, sales, marketing, and administration in the United States, Japan and Europe. The following table shows the details of the facilities, severance and other restructuring costs accrual for the nine months ended March 31, 2003:

Page 12

In addition, during the first fiscal quarter of 2003, KLA-Tencor received $15.2 million as a second installment on the sale of software and intellectual property associated with its iSupport™ on-line customer support technology, which was netted against the above non-recurring charges, resulting in a reported net gain of $9.4 million.

NOTE 6 – COMMITMENTS AND CONTINGENCIES

Facilities

KLA-Tencor leases certain of its facilities under operating leases, which qualify for operating lease accounting treatment under SFAS 13, “Accounting for Leases,” and, as such, these facilities are not included on its Condensed Consolidated Balance Sheet.

The following is a schedule of operating lease commitments as of March 31, 2003 (in thousands):

The lease agreement for certain Milpitas and San Jose, California facilities had a term of five years ending in November 2002, with an option to extend up to two more years. Under the terms of the lease, KLA-Tencor, at its option, could acquire the properties at their original cost or arrange for the properties to be acquired. In November 2002, the Company purchased these facilities at the end of the lease term. The purchase transaction increased land and property by approximately $120 million and decreased cash by the same amount.

Factoring

KLA-Tencor has agreements with two banks to sell without recourse certain of its trade receivables and promissory notes. During the three months and nine months ended March 31, 2003, approximately $31 million and $79 million, respectively, of receivables were sold under these arrangements. As of March 31, 2003, approximately $48 million of receivables sold under these arrangements were outstanding. The total amount available under the facility is the Japanese yen equivalent of $92 million based upon exchange rates as of March 31, 2003. KLA-Tencor does not believe it is materially at risk for any losses as a result of this agreement.

Purchase Commitments

KLA-Tencor maintains certain open inventory purchase commitments with its suppliers to ensure a smooth and continuous supply chain for key components. KLA-Tencor’s liability in these purchase commitments is generally restricted to a forecasted time-horizon as mutually agreed upon between the parties. This forecast time-horizon can vary amongst different suppliers. The Company’s open inventory purchase commitments were less than $60 million as of March 31, 2003.

Derivative Instruments

KLA-Tencor’s foreign subsidiaries operate and sell KLA-Tencor’s products in various global markets. As a result, KLA-Tencor is exposed to changes in foreign currency exchange rates. KLA-Tencor utilizes foreign currency forward exchange contracts to hedge against certain future movements in foreign exchange rates that affect certain foreign currency denominated sales and purchase transactions. KLA-Tencor does not use derivative financial instruments for speculative or trading purposes. At March 31, 2003, KLA-Tencor had foreign exchange forward contracts maturing throughout fiscal 2003 to sell and purchase $185 million and $67 million, respectively, in foreign currency, primarily Japanese yen.

Page 13

Guarantees

During the quarter ended December 31, 2002 KLA-Tencor adopted Financial Accounting Standards Board Interpretation No. 45 (“FIN 45”), ” Guarantor’s Requirements for Guarantees, including Indirect Indebtedness of Others”. FIN 45 requires disclosures concerning KLA-Tencor’s obligations under certain guarantees.

The following table provides the changes in the product warranty accrual, as required by FIN 45 for the nine months ended March 31, 2003:

In connection with certain business combinations and purchased technology transactions, KLA-Tencor was subject to certain contingent consideration arrangements at March 31, 2003. These arrangements are based upon sales volume or the occurrence of other events subsequent to the acquisition. The payment of the contingency results in an increase to goodwill or operating expenses. Amounts paid under these arrangements have not been and are not expected to have a material effect on KLA-Tencor’s financial condition or results of operations.

Subject to certain limitations, KLA-Tencor indemnifies its current and former officers and directors for certain events or occurrences. Although the maximum potential amount of future payments KLA-Tencor could be required to make under these agreements is theoretically unlimited, based on prior experience, we believe the fair value of this liability is de minimis and no liability has been recorded.

Legal Matters

A discussion regarding certain pending legal proceedings is included in Part I, Item 3, “Legal Proceedings,” included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2002. Since the fiscal year ended June 30, 2002, certain developments have occurred with respect to the legal proceedings described in our Annual Report as follows:

ADE Corporation

On October 11, 2000, ADE Corporation (“ADE”), a competitor, filed a patent infringement lawsuit against KLA-Tencor in the U.S. District Court in Delaware. ADE claimed damages and sought an injunction under U.S. Patent No. 6,118,525 (“'525 patent”). We filed a counterclaim in the same court alleging that ADE has infringed four of our patents. We are seeking damages and a permanent injunction against ADE. In addition, we are seeking a declaration from the District Court that ADE’s patent is invalid and not infringed by KLA-Tencor. On October 22, 2001, we filed a separate action for declaratory judgment against ADE in the Northern District of California requesting a declaration that U.S. Patent No. 6,292,259 (“'259 patent”) is invalid and not infringed. That action has now been consolidated with the prior action in the Delaware proceeding, and ADE has amended its complaint in that proceeding to allege that KLA-Tencor is infringing the ‘259 patent. On August 8, 2002, the magistrate presiding over the action issued a recommendation that the court enter summary judgment in favor of KLA-Tencor on the issue of non-infringement under ADE’s ‘525 patent. On the same day, the magistrate issued recommendations that the court enter summary judgment in favor of ADE on the issue of non-infringement of two of KLA-Tencor’s patents. The district court judge subsequently substantially adopted the recommendations of the magistrate regarding claims construction.

Page 14

Tokyo Seimitsu Co. Ltd.

On June 27, 2001, we sued Tokyo Seimitsu Co. Ltd. and TSK America Inc. ("TSK"), a competitor, in the U.S. District Court in the Northern District of California alleging that TSK infringes on one of the Company's patents. The suit seeks damages and an injunction under U.S. Patent No. 4,805,123 ("`123 patent"). TSK filed a counterclaim in the same court seeking a declaration that the `123 patent is invalid, unenforceable and not infringed, and also alleged violations of the antitrust and unfair competition laws. The district court judge has entered a claims construction ruling that calls into question the validity of the patent in suit. We are examining remedies in connection with that determination.

NOTE 7 – GOODWILL AND OTHER INTANGIBLE ASSETS

Effective July 1, 2001, KLA-Tencor adopted Statement of Financial Accounting Standards No. 141, “Business Combinations,” and No. 142, “Goodwill and Other Intangible Assets.” Under these accounting standards, KLA-Tencor ceased amortization of goodwill recorded for business combinations consummated prior to July 1, 2001, and reclassified amounts attributed to workforce in acquisitions made prior to July 1, 2001 that did not meet the criteria for separate recognition as other intangible assets under SFAS 141 to goodwill.

The net carrying value of goodwill recorded through acquisitions is $16.2 million as of March 31, 2003. In accordance with SFAS 142, KLA-Tencor concluded there was no impairment of goodwill. The net carrying value of other intangible assets as of March 31, 2003 is $4.4 million; the components of which are as follows (in thousands):

Other intangible assets are amortized on a straight-line basis over their estimated useful lives. During the quarter ended March 31, 2003, management evaluated certain intangible assets using a fair-value approach based on discounted future cash flows and determined that these assets were impaired. For the three months ended March 31, 2003, amortization expense for other intangible assets was $2.6 million, including an impairment charge of $2.0 million compared to $0.6 million, for the three months ended March 31, 2002. For the nine months ended March 31, 2003, amortization expense for other intangible assets was $3.8 million, including an impairment charge of $2.0 million compared to $1.5 million for the nine months ended March 31, 2002. Based on intangibles assets recorded at March 31, 2003, and assuming no subsequent impairment of the underlying assets, the annual estimated amortization expense is expected to be as follows:

NOTE 8 – GEOGRAPHIC INFORMATION

KLA-Tencor is engaged primarily in designing, manufacturing, and marketing yield management and process control systems for the semiconductor industry. KLA-Tencor conducts business globally and has significant operations outside the United States, which include a manufacturing facility in Israel and sales, marketing and service offices in Europe, Japan, and the Asia Pacific region. Geographical revenue is attributed to the geographic regions in which the customer is located. The following is a summary of operations by the indicated geographic regions for the three months and nine months ended March 31, 2003 and 2002.

Long-lived assets consist of net property and equipment, goodwill, capitalized software and other intangibles, and other long-term assets, excluding long-term deferred tax assets and are attributed to the geographic region in which they are physically located:

Page 16

The following is a summary of revenue by major products for the three months and nine months ended March 31, 2003 and 2002 (as a percentage of total revenue).

In the three and nine months ended March 31, 2003 one customer accounted for 15% and 11% of revenue, respectively. For the three and nine months ended March 31, 2002 no customer accounted for more than 10% of revenue. For the quarter ended March 31, 2003 and 2002 one customer accounted for 11% of net accounts receivable.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

FORWARD-LOOKING STATEMENTS This report contains certain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. All statements included in or incorporated by reference in this Quarterly Report on Form 10-Q, other than statements of historical fact, are forward-looking statements.

CRITICAL ACCOUNTING POLICIES

The preparation of our Condensed Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. We based these estimates and assumptions on historical experience, and evaluate them on an on-going basis to ensure they remain reasonable under current conditions. Actual results could differ from those estimates. We discuss the development and selection of the critical accounting estimates with the audit committee of our board of directors on a quarterly basis, and the audit committee has reviewed the Company’s critical accounting estimates as described in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2002, filed with the SEC on September 20, 2002. During the nine months ended March 31, 2003 we revised the critical accounting policies to include the following policy regarding income taxes.

Page 18

Income Taxes

We account for income taxes in accordance with SFAS No. 109, “Accounting for Income Taxes,” which requires that deferred tax assets and liabilities be recognized using enacted tax rates for the effect of temporary differences between the book and tax bases of recorded assets and liabilities. SFAS No. 109 also requires that deferred tax assets be reduced by a valuation allowance if it is more likely than not that a portion of the deferred tax asset will not be realized. We have determined that our future taxable income will be sufficient to recover all of our deferred tax assets. However, should there be a change in our ability to recover our deferred tax assets, we could be required to record a valuation allowance against our deferred tax assets. This would result in an increase to our tax provision in the period in which we determined that the recovery was not probable.

We provide for income taxes based upon an annual estimated effective income tax rate. The effective tax rate is highly dependent upon the geographic composition of worldwide earnings, tax regulations governing each region, availability of tax credits and the effectiveness of our tax planning strategies. We carefully monitor the changes in many factors and adjust our effective income tax rate on a timely basis. If actual results differ from these estimates, this could have a material effect on our financial condition and results of operations.

RESULTS OF OPERATIONS

KLA-Tencor Corporation is the world’s leading supplier of process control and yield management solutions for the semiconductor and related microelectronics industries. Our comprehensive portfolio of products, software, analysis, services and expertise is designed to help integrated circuit manufacturers manage yield throughout the entire wafer fabrication process – from research and development to final mass production yield analysis.

We continue to face a significant downturn in the semiconductor industry, which started in early calendar year 2001. In calendar year 2001, the demand for semiconductors dropped by approximately 32% and remained flat to slightly higher in calendar year 2002. Although new orders grew sequentially by approximately $30 million in the three months ended March 31, 2003, compared to the previous quarter, we are still cautious about the timing of a broad based turnaround in the growth of demand for semiconductors. Electronics industry analysts forecast calendar year 2003 to show slightly positive growth over calendar year 2002, which we believe will translate into slightly positive growth for semiconductor capital equipment business.

Over the longer term, we expect process control to continue to represent a higher percentage of our customers’ capital spending. We believe this increase in process control spending will be driven by the demand for more precise diagnostics capabilities to address multiple new defects as a result of further shrinking of device feature sizes, the transition to copper and other new materials, and the transition to new 300-millimeter fabs. We anticipate these factors will drive increased demand for our products and services when the semiconductor industry recovers.

Page 19

KLA-Tencor’s backlog for unshipped system orders as of March 31, 2003 was approximately $473 million, a majority of which we expect to ship over the next six to nine months. In addition, we have $357 million of SAB 101 deferred revenue that is related to products that have been delivered but are awaiting written acceptance from the customer.

Revenue and Gross Margin

Product revenue decreased $68 million, or 22%, to $239 million for the three months ended March 31, 2003 from $307 million for the three months ended March 31, 2002. Product revenue declined $296 million, or 27%, to $820 million for the nine months ended March 31, 2003 from $1.1 billion for the nine months ended March 31, 2002. Our decline in product revenue resulted primarily from reduced capital spending by our customers as a result of a significant reduction in the demand for semiconductors over the last two years. International revenue increased to 65% of revenue, in the three months ended March 31, 2003 from 63% in the same period of the prior fiscal year, due to higher revenue in Taiwan partially offset by lower revenue in Europe. International revenue increased to 72% of revenue for the nine months ended March 31, 2003 from 71% in the same period of the prior fiscal year, due to relatively higher revenue in Taiwan partially offset by lower revenue in Asia Pacific. For the three and nine months ended March 31, 2003 one customer accounted for 15% and 11% of revenue, respectively. For the three and nine months ended March 31, 2002 no customer accounted for more than 10% of revenue.

Service revenue is generated from maintenance service contracts, as well as time and material billable service calls made to our customers after the expiration of the warranty period. Service revenue was $65 million and $51 million for the three months ended March 31, 2003 and 2002, respectively. Service revenue was $195 million and $149 million for the nine months ended March 31, 2003 and 2002, respectively. Service revenue continued to increase throughout fiscal year 2002 and the first nine months of fiscal 2003 as our installed base of equipment at customer sites continued to grow. The amount of service revenue generated is generally proportional to the number of post-warranty systems installed at customer sites and the degree of utilization of those systems. We expect service revenue to remain flat to slightly higher in the next few quarters.

Gross margin as a percentage of revenue was 49% for the three and nine months ended March 31, 2003, compared to 49% and 50% for the same periods in the prior fiscal year, respectively. Gross margin declined year over year primarily due to an increased percentage of sales in the service business and reduced capacity utilization resulting from lower production volume, partially offset by favorable warranty costs experienced by our latest generation products as they continue to mature. In the near term, we expect our gross margin percentage to remain relatively flat.

Engineering, Research and Development

Net engineering, research and development (“R&D”) expenses were $61 million and $204 million for the three and nine months ended March 31, 2003, compared to $71 million and $218 million for the same periods in the prior fiscal year. As a percentage of revenue, R&D expenses were 20% for the three and nine months ended March 31, 2003, compared to 20% and 17% for the same periods in the prior fiscal year. The absolute dollars for R&D investment decreased primarily due to engineering programs reaching certain milestones that resulted in reductions in labor and material expense, as well as cost saving measures such as company mandated time-off and reduction in discretionary spending implemented over the last several quarters in response to the industry slow down.

Gross engineering, research and development expenses were partially offset by external funding received under certain strategic development programs conducted with several of our customers and government grants. We received external funding of $3 million and $13 million for the three and nine months ended March 31, 2003, respectively compared to $5 million and $10 million for the three and nine months ended March 31, 2002, respectively.

Our future operating results will depend significantly on our ability to produce products and provide services that have a competitive advantage in our marketplace. To do this, we believe that we must continue to make substantial investments in our research and development efforts. We remain committed to product development in new and emerging technologies as we address the further shrinking of device feature sizes, the transition to copper and other new materials, and the transition to new 300-millimeter fabs. Our investments in new technology and existing product enhancements are intended to enable our customers to achieve a higher return on their capital investments and higher productivity through cost-effective, leading edge technology solutions.

Selling, General and Administrative

Selling, general and administrative expenses were $61 million and $196 million for the three and nine months ended March 31, 2003, compared to $66 million and $220 million for the same periods in the prior fiscal year. As a percentage of revenue, selling, general and administrative expenses were 20% and 19% for the three and nine months ended March 31, 2003, respectively, compared to 19% and 17% for the same periods in the prior fiscal year. The absolute dollars for selling, general and administrative expenses decreased primarily due to company mandated time-off, reductions in labor and discretionary spending as well as other cost saving measures implemented over the last several quarters in response to the industry slowdown and the ongoing global economic weakness. We expect our selling, general and administrative expenses to be flat to slightly down in absolute dollars as we continue to realize the benefits from these cost saving measures.

Restructuring and Other Costs

During the three months ended September 30, 2002, we restructured certain of our operations and facilities to accommodate the planned occupancy of our Livermore campus and to streamline our operations due to the industry downturn. Restructuring costs were classified into two main categories: facilities and other charges of $4.6 million and severance and benefits of $1.1 million. As part of our facilities consolidation, we are exiting several of our leased buildings and have included the remaining net book value of the related leasehold improvements as well as the future lease payments, net of anticipated sublease revenue, in the charge. If facilities rental rates continue to deteriorate or if it takes longer than expected to sublease these facilities, the actual loss could increase. Severance and benefits include involuntary termination of approximately 70 personnel from manufacturing, engineering, sales, marketing, and administration in the United States, Japan and Europe. The following table shows the details of the facilities, severance and other restructuring costs accrual as of March 31, 2003:

Page 21

In addition, during the first fiscal quarter of 2003, we received $15.2 million as a second installment on the sale of software and intellectual property associated with our iSupport™ on-line customer support technology, which we netted against the above non-recurring charges, resulting in a net reported gain of $9.4 million.

Interest Income and Other, Net

Interest income and other, net, was $10 million and $32 million for the three and nine months ended March 31, 2003, compared to $9 million and $32 million in the same periods in the prior fiscal year. Interest income and other, net is comprised primarily of interest income earned on our investment and cash portfolio, gains realized on sales of marketable securities, as well as income recognized upon settlement of certain foreign currency contracts and unrealized gains and losses from marking to market investments classified as trading securities.

Provision for Income Taxes

Our effective tax rate for the three months and nine months ended March 31, 2003 was 24%. This was lower than the effective tax rate of 26% realized in the same periods of the prior fiscal year. The overall reduction in our effective tax rate was primarily the result of more R&D credit and tax-exempt interest compared relatively to these same items as a percentage of pre-tax income of the same periods during the prior fiscal year. There currently is pending legislation to repeal the existing export incentive provided by the United States Internal Revenue Code and to replace it with a tax incentive tied to U.S. based manufacturing. If the legislation were approved it may increase our effective tax rate in future periods.

Stock Option and Incentive Plans

KLA-Tencor’s stock option program is a broad-based, long-term retention program that is intended to attract and retain qualified management and technical employees (“knowledge employees”), and align stockholder and employee interests. Under KLA-Tencor’s stock option plans, options generally have vesting periods of four or five years, are exercisable for a period not to exceed ten years from the date of issuance and are granted at prices not less than the fair market value of KLA-Tencor’s common stock at the grant date. This program consists of three plans: one under which non-employee directors may be granted options to purchase shares of our stock, another in which officers, key employees, consultants and all other employees may be granted options and a third in which consultants and all employees other than directors and officers may be granted options to purchase shares of our stock. Substantially all of our employees that meet established performance goals and that qualify as “knowledge employees” participate in one of our stock option plans. Options granted to employees from fiscal year 2000 through the nine months ended March 31, 2003 are summarized as follows (in thousands):

Page 22

During the nine months ended March 31, 2003, the Company granted options to purchase approximately 4.7 million shares of stock to employees. The net options granted after forfeiture represented 1.5% of total outstanding shares of approximately 189.5 million as of March 31, 2003.

During the nine months ended March 31, 2003, there were 268,000 options granted to the top five officers, who represent the chief executive officer and each of the four other most highly compensated executive officers whose salary plus bonus exceeded $100,000 for the fiscal year ended June 30, 2002. All stock option grants to officers are made with a review by, and with the approval of the Compensation Committee of the Board of Directors. All members of the Compensation Committee are independent directors, as defined in the applicable rules for issuers traded on the NASDAQ Stock Market.

Page 23

The following table summarizes stock options exercised by the top five officers during the nine months ended March 31, 2003:

⁽¹⁾In August 2002, the Company reserved an additional 5,691,826 shares of its common stock in accordance with the provisions of the 1982 Stock Option plan.
⁽²⁾In August 2002, the Board of Directors authorized an increase in the number of securities reserved for additional future issuance under the Company's stock option plans (other than the Company's Director Stock Option Plan) of an aggregate of 7,589,102 shares. ⁽³⁾Officers and directors are not eligible to receive options granted under this plan.

Page 24

On November 8, 2002, the Compensation Committee of the Board of Directors authorized approximately 5.5 million options as part of the fiscal year 2002 annual performance review cycle for KLA-Tencor. There were approximately 5.0 million options authorized to non-executive employees under the 2000 Stock Option Plan, and 0.5 million options authorized to executive employees under the 1982 Stock Option Plan. KLA-Tencor intends to grant these options over the course of the fiscal year ending June 30, 2003. The first installment of 1.4 million options (1.3 million to non-executive employees and 0.1 million to executive employees) was granted on November 8, 2002. On January 28, 2002, a second installment of 2.9 million options (2.7 million to non-executive employees and 0.2 million to executive employees) was granted, as part of the fiscal year 2002 annual performance cycle review of KLA-Tencor. Additionally, 60,000 options were granted on November 8, 2002 to outside directors under the 1998 Outside Director Option Plan.

LIQUIDITY AND CAPITAL RESOURCES

Cash, cash equivalents and short-term investments balances during the three months ended March 31, 2003 increased to $905 million from $673 million at June 30, 2002. In addition marketable securities classified as long-term at March 31, 2003 decreased to $492 million from $660 million at June 30, 2002. KLA-Tencor has historically financed its operations through cash generated from operations. Net cash provided by operating activities for the nine months ended March 31, 2003 was $187 million, compared to $184 million of net cash from operating activities for the same period of the prior fiscal year. This increase primarily resulted from lower accounts receivable and inventory balances, partially offset by a decrease in accounts payable. Accounts receivable declined primarily due to strong collections, as well as lower product shipments. Inventories declined due to aggressive monitoring and control of inventory purchases and lower manufacturing activity. Net cash used by investing activities for the nine months ended March 31, 2003 was $38 million, compared to $372 million used in investing activities for the same period of the prior fiscal year, primarily from decreased net purchases of marketable securities partially offset by our purchase of certain of the leased buildings in November 2002.

Net cash used in financing activities for the nine months ended March 31, 2003 was $12 million as compared to $31 million for the same period of the prior fiscal year. This decline was primarily due to decreases in stock repurchases partially offset by decreases in exercises of stock options. We paid $63 million for the repurchase of our common stock under our stock repurchase program during the nine months ended March 31, 2003 compared to $118 million for the same period of the prior year.

The lease agreement for certain Milpitas and San Jose, California facilities had a term of five years ending in November 2002, with an option to extend up to two more years. Under the terms of the lease, we, at our option, could acquire the properties at their original cost or arrange for the properties to be acquired. In November 2002, we purchased these facilities at the end of the lease term. The purchase transaction increased land and property by approximately $120 million and decreased cash by the same amount.

The following is a schedule summarizing our significant operating lease commitments as of March 31, 2003 (in millions):

We have agreements with two banks to sell without recourse certain of our trade receivables and promissory notes. During the three and nine months ended March 31, 2003, approximately $31 million and $79 million of receivables, respectively, were sold under these arrangements. As of March 31, 2003, approximately $48 million of receivables sold under these arrangements were outstanding. The total amount available under the facility is the Japanese yen equivalent of $92 million based upon exchange rates as of March 31, 2003. We do not believe we are materially at risk for any losses as a result of this agreement.

Additionally, we maintain certain open inventory purchase commitments with our suppliers to ensure a smooth and continuous supply chain for key components. Our liability in these purchase commitments is generally restricted to a forecasted time-horizon as mutually agreed upon between the parties. This forecast time-horizon can vary amongst different suppliers. As such, it is difficult to precisely report our true open commitments at any particular point in time. However, we estimate our open inventory purchase commitments to be less than $60 million as of March 31, 2003.

Working capital increased to $1.11 billion as of March 31, 2003, compared to $932 million at June 30, 2002. We believe that existing liquid capital resources and funds generated from operations combined with the ability to borrow funds will be adequate to meet our business requirements for the foreseeable future, including potential acquisitions or strategic investments, capital expenditures for the expansion or upgrading of manufacturing capacity and working capital requirements. However, we can give no assurances that we will continue to generate sufficient funds from operations or that we will be able to borrow funds on reasonable terms in the future.

FACTORS AFFECTING RESULTS, INCLUDING RISKS AND UNCERTAINTIES

Fluctuations in Operating Results and Stock Price

Our operating results have varied widely in the past, and our future operating results will continue to be subject to quarterly variations based upon numerous factors, including those listed in this section and those set forth in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Item 1, “Business” in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2002, filed with the SEC on September 20, 2002. In addition, future operating results may not follow any past trends. We believe the factors that could make our results fluctuate and difficult to predict include:
o global economic uncertainty; o the cyclical nature of the semiconductor industry;
o changing international economic conditions;
o competitive pressure;
o our ability to develop and implement new technologies and introduce new products;
o our ability to manage our manufacturing requirements;
o our ability to protect our intellectual property;
o our ability to attract, retain, and replace key employees; and o worldwide political instability.

Operating results also could be affected by sudden changes in customer requirements, currency exchange rate fluctuations and other economic conditions affecting customer demand and the cost of operations in one or more of the global markets in which we do business. As a result of these or other factors, we could fail to achieve our expectations as to future revenue, gross profit and income from operations. Our failure to meet the performance expectations set and published by external sources could result in a sudden and significant drop in the price of our stock, particularly on a short-term basis, and could negatively affect the value of any investment in our stock.

Global Economic Uncertainty

Our business is ultimately driven by the global demand for electronic devices by consumers and businesses. This end-user demand has been significantly depressed over the last few quarters and there has been very limited visibility as to the timing of turnaround in demand growth and from which sector this growth will come. A protracted global economic slowdown will continue to exacerbate this issue and may adversely affect our business and results of operation.

Semiconductor Equipment Industry Volatility

The semiconductor equipment industry is highly cyclical. The purchasing decisions of our customers are highly dependent on the economies of both the local markets in which they are located and the semiconductor industry worldwide. The timing, length and severity of the up-and-down cycles in the semiconductor equipment industry are difficult to predict. This cyclical nature of the industry in which we operate affects our ability to accurately predict future revenue and, thus, future expense levels. When cyclical fluctuations result in lower than expected revenue levels, operating results may be adversely affected and cost reduction measures may be necessary in order for us to remain competitive and financially sound. During a down cycle, we must be in a position to adjust our cost and expense structure to prevailing market conditions and to continue to motivate and retain our key employees. In addition, during periods of rapid growth, we must be able to increase manufacturing capacity and personnel to meet customer demand. We can provide no assurance that these objectives can be met in a timely manner in response to industry cycles. If we fail to respond to industry cycles, our business could be seriously harmed.

Page 27

We are currently in an industry down cycle. We are not able to predict when the semiconductor industry will recover. During a down cycle, the semiconductor industry typically experiences excess production capacity that causes semiconductor manufacturers to decrease capital spending. We generally do not have long-term volume production contracts with our customers, and we do not control the timing or volume of orders placed by our customers. Whether and to what extent our customers place orders for any specific products, as well as the mix and quantities of products included in those orders, are factors beyond our control. Insufficient orders, especially in our down cycles, will result in under-utilization of our manufacturing facilities and infrastructure and will negatively affect our operating results and financial condition.

International Trade and Economic Conditions

We serve an increasingly global market. A majority of our annual revenue is derived from outside the United States, and we expect that international revenue will continue to represent a substantial percentage of our revenue. Our international revenue and operations are affected by economic conditions specific to each country and region. Because of our significant dependence on international revenue, a decline in the economies of any of the countries or regions in which we do business could negatively affect our operating results.

Managing global operations and sites located throughout the world presents challenges associated with, among other things, cultural diversity and organizational alignment. Moreover, each region in the global semiconductor equipment market exhibits unique characteristics that can cause capital equipment investment patterns to vary significantly from period to period. Periodic local or international economic downturns, trade balance issues, political instability in regions where we have operations, such as Israel, and fluctuations in interest and currency exchange rates could negatively affect our business and results of operations. Although we attempt to manage near-term currency risks through the use of hedging instruments, there can be no assurance that such efforts will be adequate. In addition, our ability to address normal business transaction issues in Asia is at risk due to the Severe Acute Respiratory Syndrome outbreak in Asia, which has resulted in management’s decision to limit travel to Asia in accordance with the World Health Organization’s recommendations.

Competition

Our industry includes large manufacturers with substantial resources to support customers worldwide. Our future performance depends, in part, upon our ability to continue to compete successfully worldwide. Some of our competitors are diversified companies with greater financial resources and more extensive research, engineering, manufacturing, marketing and customer service and support capabilities than we can provide. We face competition from companies whose strategy is to provide a broad array of products and services, some of which compete with the products and services that we offer. These competitors may bundle their products in a manner that may discourage customers from purchasing our products. In addition, we face competition from smaller emerging semiconductor equipment companies whose strategy is to provide a portion of the products and services, which we offer, using innovative technology to sell products into specialized markets. Loss of competitive position could negatively impact our prices, customer orders, revenue, gross margin, and market share, any of which would negatively affect our operating results and financial condition. Our failure to compete successfully with these other companies would seriously harm our business.

Technological Change and Customer Requirements

Success in the semiconductor equipment industry depends, in part, on continual improvement of existing technologies and rapid innovation of new solutions. For example, the semiconductor industry continues to shrink the size of semiconductor devices, transition to copper and other new materials, and transition to new 300-millimeter fabs. While we expect these trends will increase our customers’ reliance on our diagnostic products, we cannot ensure that they will directly improve our business. These and other evolving customer needs require us to respond with continued development programs and to cut back or discontinue older programs, which may no longer have industry-wide support. Technical innovations are inherently complex and require long development cycles and appropriate professional staffing. Our competitive advantage and future business success depend on our ability to accurately predict evolving industry standards, to develop and introduce new products which successfully address changing customer needs, to win market acceptance of these new products and to manufacture these new products in a timely and cost-effective manner. If we do not develop and introduce new products and technologies in a timely manner in response to changing market conditions or customer requirements, our business could be seriously harmed.

Page 28

In this environment, we must continue to make significant investments in research and development in order to enhance the performance and functionality of our products, to keep pace with competitive products and to satisfy customer demands for improved performance, features and functionality. There can be no assurance that revenue from future products or product enhancements will be sufficient to recover the development costs associated with such products or enhancements or that we will be able to secure the financial resources necessary to fund future development. Substantial research and development costs typically are incurred before we confirm the technical feasibility and commercial viability of a product, and not all development activities result in commercially viable products. In addition, we cannot ensure that these products or enhancements will receive market acceptance or that we will be able to sell these products at prices that are favorable to us. Our business will be seriously harmed if we are unable to sell our products at favorable prices or if the market in which we operate does not accept our products.

Key Suppliers

We use a wide range of materials in the production of our products, including custom electronic and mechanical components, and we use numerous suppliers to supply these materials. We generally do not have guaranteed supply arrangements with our suppliers. Because of the variability and uniqueness of customers’ orders, we do not maintain an extensive inventory of materials for manufacturing. We seek to minimize the risk of production and service interruptions and/or shortages of key parts by selecting and qualifying alternative suppliers for key parts, monitoring the financial stability of key suppliers and maintaining appropriate inventories of key parts. Although we make reasonable efforts to ensure that parts are available from multiple suppliers, key parts may be available only from a single supplier or a limited group of suppliers. Our business would be harmed if we do not receive sufficient parts to meet our production requirements in a timely and cost-effective manner.

Manufacturing Disruption

Most of our manufacturing facilities are located in the United States, with a small operation located in Israel. Operations at our manufacturing facilities and our assembly subcontractors are subject to disruption for a variety of reasons, including work stoppages, acts of war, terrorism, fire, earthquake, energy shortages, flooding or other natural disasters. Such disruption could cause delays in shipments of products to our customers. We cannot ensure that alternate production capacity would be available if a major disruption were to occur or that, if it were available, it could be obtained on favorable terms. Such disruption could result in cancellation of orders or loss of customers and could seriously harm our business.

Page 29

Intellectual Property Obsolescence and Infringement

Our success is dependent in part on our technology and other proprietary rights. We own various United States and international patents and have additional pending patent applications relating to some of our products and technologies. The process of seeking patent protection is lengthy and expensive, and we cannot be certain that pending or future applications will actually result in issued patents or that issued patents will be of sufficient scope or strength to provide meaningful protection or commercial advantage to us. Other companies and individuals, including our larger competitors, may develop technologies and obtain patents relating to our technology that is similar or superior to our technology or may design around the patents we own, adversely affecting our business.

We also maintain trademarks on certain of our products and services and claim copyright protection for certain proprietary software and documentation. However, we can give no assurance that our trademarks and copyrights will be upheld or successfully deter infringement by third parties.

While patent, copyright and trademark protection for our intellectual property is important, we believe our future success in highly dynamic markets is most dependent upon the technical competence and creative skills of our personnel. We attempt to protect our trade secrets and other proprietary information through confidentiality and other agreements with our customers, suppliers, employees and consultants and through other security measures. We also maintain exclusive and non-exclusive licenses with third parties for strategic technology used in certain products. However, these employees, consultants and third parties may breach these agreements and we may not have adequate remedies for wrongdoing. In addition, the laws of certain territories in which we develop, manufacture or sell our products may not protect our intellectual property rights to the same extent as do the laws of the United States.

As is typical in the semiconductor equipment industry, from time to time we have received communications from other parties asserting the existence of patent rights, copyrights, trademark rights or other intellectual property rights which they believe cover certain of our products, processes, technologies or information. Our customary practice is to evaluate such assertions and to consider whether to seek licenses where appropriate. However, we cannot ensure that licenses can be obtained or, if obtained, will be on acceptable terms or that costly litigation or other administrative proceedings will not occur. The inability to obtain necessary licenses or other rights on reasonable terms could seriously harm our operating results and financial condition.

Key Employees

Our employees are vital to our success, and our key management, engineering and other employees are difficult to replace. We generally do not have employment contracts with our key employees. Further, we do not maintain key person life insurance on any of our employees. The expansion of high technology companies worldwide has increased demand and competition for qualified personnel. If we are unable to retain key personnel, or if we are not able to attract, assimilate or retain additional highly qualified employees to meet our needs in the future, our business and operations could be harmed. These factors could seriously harm our business.

Acquisitions

In addition to our efforts to develop new technologies from internal sources, we also seek to acquire new technologies from external sources. As part of this effort, we may make acquisitions of, or significant investments in, businesses with complementary products, services and/or technologies. Acquisitions involve numerous risks, including management issues and costs in connection with the integration of the operations and personnel, technologies and products of the acquired companies, the possible write-downs of impaired assets, and the potential loss of key employees of the acquired companies. The inability to manage these risks effectively could seriously harm our business.

Litigation

From time to time we are involved in litigation of various types, including litigation that alleges infringement of intellectual property rights and other claims. Litigation tends to be expensive and requires significant management time and attention and could have a negative effect on our results of operations or business if we lose or have to settle a case on significantly adverse terms. If we lose in a dispute concerning intellectual property, a court could require us to pay substantial damages and/or royalties or could issue an injunction prohibiting us from using essential technologies. For these and other reasons, this type of litigation could have a material adverse effect on our business, financial condition and results of operations. Also, although we may seek to obtain a license under a third party’s intellectual property rights in order to bring an end to certain claims or actions asserted against us, we may not be able to obtain such a license on reasonable terms or at all.

Terrorism and Political Instability

The threat of terrorism targeted at the regions of the world in which we do business, including the United States, increases the uncertainty in our markets and may delay any recovery in the general economy. Any delay in the recovery of the economy and the semiconductor industry could seriously impact our business.

Increased international political instability, as demonstrated by the September 2001 terrorist attacks, disruption in air transportation and further enhanced security measures as a result of the terrorist attacks, and the continuing instability in the Middle East, may hinder our ability to do business and may increase our costs of operations. Such continuing instability could cause us to incur increased costs in transportation, make such transportation unreliable, increase our insurance costs, and cause international currency markets to fluctuate. This same instability could have the same effects on our suppliers and their ability to timely deliver their products. If this international political instability continues or increases, our business and results of operations could be harmed.

Effects of Recent Accounting Pronouncements

We have adopted Statement No. 143, (“SFAS 143”) “Accounting for Obligations Associated with the Retirement of Long-Lived Assets” and Statement No. 144 (“SFAS 144”) “Accounting for the Impairment of Disposal of Long-Lived Assets”. SFAS 143 establishes accounting standards for the recognition and measurement of an asset retirement obligation and its associated asset retirement cost. It also provides guidance for legal obligations associated with the retirement of tangible long-lived assets. SFAS 144 establishes a single accounting model for the impairment or disposal of long-lived assets, including discontinued operations. Adoption of these pronouncements did not have a significant effect on our consolidated financial statements.

In June 2002, the FASB issued Statement No. 146 (“SFAS 146”), “Accounting for Costs Associated with Exit or Disposal Activities.” SFAS 146 addresses financial accounting and reporting for costs associated with exit or disposal activities, and nullifies Emerging Issues Task Force (“EITF”) Issue No. 94-3, Liabilities Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring). This Statement requires that a liability for costs associated with an exit or disposal activity be recognized and measured initially at fair value only when the liability is incurred. SFAS 146 will be effective for exit or disposal activities that are initiated after March 31, 2003. The standard will in certain circumstances change the timing of recognition of restructuring costs.

In November 2002, EITF reached a consensus on Issue No. 00-21, “Accounting for Revenue Arrangements with Multiple Deliverables.” This issue addresses determination of whether an arrangement involving more than one deliverable contains more than one unit of accounting and how arrangement consideration should be measured and allocated to the separate units of accounting. EITF Issue No. 00-21 will be effective for revenue arrangements entered into in fiscal periods beginning after June 15, 2003 or we may elect to report the change in accounting as a cumulative-effect adjustment. We are reviewing EITF Issue No. 00-21 and have not yet determined the impact this issue will have on our consolidated operating results and financial position.

In January 2003, the FASB issued FASB Interpretation No. 46 (“FIN 46”), “Consolidation of Variable Interest Entities”, an Interpretation of ARB No. 51.  FIN 46 requires certain variable interest entities to be consolidated by the primary beneficiary of the entity if the equity investors in the entity do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. FIN 46 is effective immediately for all new variable interest entities created or acquired after January 31, 2003. For variable interest entities created or acquired prior to February 1, 2003, the provisions of FIN 46 must be applied for the first interim or annual period beginning after June 15, 2003.  We believe that the adoption of this standard will have no material impact on our consolidated financial statements.  

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to financial market risks, including changes in interest rates, foreign currency exchange rates and marketable equity security prices. To mitigate these risks, we utilize derivative financial instruments. We do not use derivative financial instruments for speculative or trading purposes. All of the potential changes noted below are based on sensitivity analyses performed on our financial position at March, 31, 2003. Actual results may differ materially.

As of March 31, 2003, we had an investment portfolio of fixed income securities of $798 million excluding those classified as cash and cash equivalents. These securities, as with all fixed income instruments, are subject to interest rate risk and will fall in value if market interest rates increase. If market interest rates were to increase immediately and uniformly by 10% from levels as of March 31, 2003, the fair value of our investment portfolio would decline by $3 million.

As of March 31, 2003, we had net forward contracts to sell U.S. dollar equivalent of $118 million in foreign currency in order to hedge our currency exposures. If we had entered into these contracts on March 31, 2003, the U.S. dollar equivalent would be $117 million. A 10% adverse move in currency exchange rates affecting the contracts would decrease the fair value of the contracts by $15 million. However, if this occurred, the fair value of the underlying exposures hedged by the contracts would increase by a similar amount. Accordingly, we believe that our hedging strategy should yield no material net impact to net income or cash flows.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of disclosure controls and procedures

Within 90 days prior to the date of this report (the Evaluation Date), the Company’s Chief Executive Officer (principal executive officer) and Executive Vice President and Chief Financial Officer (principal financial officer) with the participation of other members of management, carried out an evaluation of the effectiveness of the Company’s “disclosure controls and procedures” (as defined in the Securities Exchange Act of 1934 Rules 13a-14(c) and 15(d)-14(c)). Based on that evaluation, these officers have concluded that as of the Evaluation Date, the Company’s disclosure controls and procedures were adequate and designed to ensure that material information relating to the Company and the Company’s consolidated subsidiaries would be made known to them by others within those entities and are effective to ensure that the information required to be disclosed by us in reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed and reported within the time periods specified in Securities and Exchange Commission rules and forms.

Changes in internal controls

There have been no significant changes in the Company’s internal controls or in other factors that could significantly affect these controls subsequent to the date of their evaluation.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Legal Matters

A discussion regarding certain pending legal proceedings is included in Part I, Item 3, “Legal Proceedings,” included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2002. Since the fiscal year ended June 30, 2002, certain developments have occurred with respect to the legal proceedings described in our Annual Report as follows:

ADE Corporation

On October 11, 2000, ADE Corporation (“ADE”), a competitor, filed a patent infringement lawsuit against KLA-Tencor in the U.S. District Court in Delaware. ADE claimed damages and sought an injunction under U.S. Patent No. 6,118,525 (“'525 patent”). We filed a counterclaim in the same court alleging that ADE has infringed four of our patents. We are seeking damages and a permanent injunction against ADE. In addition, we are seeking a declaration from the District Court that ADE’s patent is invalid and not infringed by KLA-Tencor. On October 22, 2001, we filed a separate action for declaratory judgment against ADE in the Northern District of California requesting a declaration that U.S. Patent No. 6,292,259 (“'259 patent”) is invalid and not infringed. That action has now been consolidated with the prior action in the Delaware proceeding, and ADE has amended its complaint in that proceeding to allege that KLA-Tencor is infringing the ‘259 patent. On August 8, 2002, the magistrate presiding over the action issued a recommendation that the court enter summary judgment in favor of KLA-Tencor on the issue of non-infringement under ADE’s ‘525 patent. On the same day, the magistrate issued recommendations that the court enter summary judgment in favor of ADE on the issue of non-infringement of two of KLA-Tencor’s patents. The district court judge subsequently substantially adopted the recommendations of the magistrate regarding claims construction.

Tokyo Seimitsu Co. Ltd.

On June 27, 2001, we sued Tokyo Seimitsu Co. Ltd. and TSK America Inc.("TSK"), a competitor, in the U.S. District Court in the Northern District of California alleging that TSK infringes on one of the Company's patents. The suit seeks damages and an injunction under U.S. Patent No. 4,805,123 ("`123 patent"). TSK filed a counterclaim in the same court seeking a declaration that the `123 patent is invalid, unenforceable and not infringed and also alleged violations of the antitrust and unfair competition laws. The district court judge has entered a claims construction ruling that calls into question the validity of the patent in suit. We are examining remedies in connection with that determination.

Although we cannot predict the outcome of these claims, we do not believe that any of these legal matters will have a material adverse effect on KLA-Tencor. Were an unfavorable ruling to occur in one or more of the pending claims, there exists the possibility of a material impact on our operating results for the period in which the ruling occurred.
