SPECIAL NOTE REGARDING 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 other than statements of historical fact may be forward-looking statements. You can identify these and other forward-looking statements by the use of words such as “may,” “will,” “could,” “would,” “should,” “expects,” “plans,” “anticipates,” “relies,” “believes,” “estimates,” “predicts,” “intends,” “potential,” “continue,” or the negative of such terms, or other comparable terminology. Forward-looking statements also include the assumptions underlying or relating to any of the foregoing statements. Such forward-looking statements include, among others, those statements regarding the future impact of the restatement of our historical financial statements, shareholder litigation and related matters arising from the discovery that we had retroactively priced stock options (primarily from July 1, 1997 to June 30, 2002) and had not accounted for them correctly; forecasts of the future results of our operations; the percentage of spending that our customers allocate to process control; orders for our products and capital equipment generally; sales of semiconductors; the allocation of capital spending by our customers; growth of revenue in the semiconductor industry, the semiconductor capital equipment industry and business; technological trends in the semiconductor industry; our future product offerings and product features; the success and market acceptance of new products; timing of shipment of backlog; the future of our product shipments and our product and service revenues; our future gross margins; the future of our selling, general and administrative expenses; international sales and operations; maintenance of our competitive advantage; success of our product offerings; creation and funding of programs for research and development; attraction and retention of employees; results of our investment in leading edge technologies; the effects of hedging transactions; the effect of the sale of trade receivables and promissory notes from customers; our future income tax rate; dividends; the completion of any acquisitions of third parties, or the technology or assets thereof; benefits received from any acquisitions and development of acquired technologies; sufficiency of our existing cash balance, investments and cash generated from operations to meet our operating and working capital requirements; and the adoption of new accounting pronouncements.

Our actual results may differ significantly from those projected in the forward-looking statements in this report. Factors that might cause or contribute to such differences include, but are not limited to, those discussed in Item 1A, “Risk Factors” as well as in Item 1, “Business” and Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this Annual Report on Form 10-K. You should carefully review these risks and also review the risks described in other documents we file from time to time with the Securities and Exchange Commission, including the Quarterly Reports on Form 10-Q that we will file in fiscal year 2007. You are cautioned not to place undue reliance on these forward-looking statements, and we expressly assume no obligations to update the forward-looking statements in this report that occur after the date hereof.

EXPLANATORY NOTE REGARDING RESTATEMENTS

This Annual Report on Form 10-K for our fiscal year ended June 30, 2006 includes restatements of the following previously filed financial statements and data (and related disclosures): (1) our consolidated financial statements as of and for our fiscal years ended June 30, 2005 and 2004; (2) our selected consolidated financial data as of and for our fiscal years ended June 30, 2005, 2004, 2003 and 2002, and (3) our unaudited quarterly financial data for the first three quarters in our fiscal year ended June 30, 2006 and for all quarters in our fiscal year ended June 30, 2005. See Note 2, “Restatement of Consolidated Financial Statements,” to Consolidated Financial Statements and Exhibit 99.1 for a detailed discussion of the effect of the restatements.

As a result of an investigation of our historical stock option practices by a Special Committee of our Board of Directors (see Item 3—Legal Proceedings), we discovered that certain of our stock options, primarily those granted from July 1, 1997 to June 30, 2002, had been retroactively priced for all employees who received these grants (less than 15% of these options were granted to executive officers). This means that the option exercise price was not the market price of the option shares on the actual grant date of the option, but instead was

 

ii


Table of Contents

a lower market price on an earlier date. The actual grant date—when the essential actions necessary to grant the option were completed, including the final determination of the number of shares to be granted to each employee and the exercise price—is the correct measurement date to determine the market price of the option shares under the accounting rules in effect at the time. More than 95% of the total in-the-money value (market price on the actual grant date minus exercise price) of all of our retroactively priced options was attributable to those granted from July 1, 1997 to June 30, 2002.

We previously applied Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees,” and its related Interpretations and provided the required pro forma disclosures under Statement of Financial Accounting Standards (“SFAS”) No. 123, “Accounting for Stock-Based Compensation,” through the fiscal year ended June 30, 2005. Under APB Opinion No. 25, a non-cash, stock-based compensation expense was recognized for any option for which the exercise price was below the market price on the actual grant date. Because each of our retroactively priced options had an exercise price below the market price on the actual grant date, there should have been a charge for each of these options under APB Opinion No. 25 equal to the number of option shares, multiplied by the difference between the exercise price and the market price on the actual grant date. That expense should have been amortized over the vesting period of the option. Starting in our fiscal year ended June 30, 2006, we adopted SFAS No. 123(R), “Share-Based Payment.” As a result, for fiscal year 2006, the additional stock-based compensation expense required to be recorded for each retroactively priced option was equal to the incremental fair value of these options on the actual grant date over the remaining vesting period of the option. We did not record these stock-based compensation expenses under APB Opinion No. 25 or SFAS No. 123(R) related to our retroactively priced options in our previously issued financial statements, and that is why we are restating them in this filing. To correct our past accounting for stock options, we recorded additional pre-tax, non-cash, stock-based compensation expense of (a) $348 million for the periods July 1, 1994 to June 30, 2005 under APB Opinion No. 25 and (b) $22 million for the year ended June 30, 2006 under SFAS No. 123(R). We expect to amortize an additional $6 million of such pre-tax charges under SFAS No. 123(R) in future periods to properly account for past retroactively priced option grants.

Management reviewed the findings of the Special Committee and conducted its own internal review of our past stock option grants and other aspects of our historical financial statements. Management agrees with the Special Committee that there was retroactive pricing of stock options granted to all option holders, primarily from July 1, 1997 to June 30, 2002. The restatements included in this Annual Report on Form 10-K include adjustments arising from the Special Committee investigation and management’s internal review.

Unless otherwise noted, all of the information in this Annual Report on Form 10-K is as of June 30, 2006. This Report does not reflect any subsequent events that occurred after June 30, 2006 other than the Special Committee investigation, resulting restatements and related matters. Our previously filed financial statements for the quarter ended September 30, 2005 are restated in our Quarterly Report on Form 10-Q for the quarter ended September 30, 2006, which we are filing concurrently with this Annual Report on Form 10-K. We will later restate our previously filed financial statements for the quarters ended December 31, 2005 and March 31, 2006 when included in our Quarterly Reports on Form 10-Q for the quarters ended December 31, 2006 and March 31, 2007, respectively. The Selected Quarterly Condensed Consolidated Financial Data and related Management’s Discussion and Analysis for the quarters ended September 30, 2005, December 31, 2005 and March 31, 2006 are included in Exhibit 99.1 of this Annual Report on Form 10-K. We have not amended and do not intend to amend any of our previously filed Annual Reports on Form 10-K or Quarterly Reports on Form 10-Q for the periods affected by the restatements. Such previous filings should not be relied upon.

ITEM 1. BUSINESS

The Company

KLA-Tencor Corporation (“KLA-Tencor” or the “Company” and also referred to as “we” or “our”) 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, services, analysis, software, and expertise is designed to help integrated circuit (“IC”) manufacturers manage yield throughout the entire fabrication process—from research and development to final mass-production yield analysis.

We offer a broad spectrum of products and services that are used by virtually every major wafer, IC and photomask manufacturer in the world. These customers turn to us for inline wafer defect monitoring; reticle and photomask defect inspection; critical dimension (“CD”) metrology; wafer overlay; film and surface measurement; and overall yield and fab-wide data analysis. Our advanced products, coupled with our unique yield technology services, allow us to deliver the yield management solutions our customers need to accelerate their yield learning rates, reduce their yield excursion risks and adopt industry-leading yield management practices.

KLA-Tencor Corporation was formed in April 1997 through the merger of KLA Instruments Corporation and Tencor Instruments, two long-time leaders in the semiconductor equipment industry, each with over 20 years of experience. KLA Instruments Corporation was incorporated in Delaware in 1975; Tencor Instruments was incorporated in California in 1976. Effective April 30, 1997, Tencor Instruments merged into a wholly owned subsidiary of KLA Instruments Corporation. Immediately following this merger, KLA Instruments Corporation changed its name to KLA-Tencor Corporation.

Industry

General Background

The semiconductor fabrication process begins with a bare silicon wafer—a round disk that is six, eight or twelve inches in diameter, about as thick as a credit card and gray in color. The process of manufacturing wafers is itself highly sophisticated, involving the creation of large ingots of silicon by pulling them out of a vat of molten silicon. The ingots are then sliced into wafers and polished to a mirror finish on the side where the circuits are to be made.

The manufacturing cycle of an integrated circuit (“IC” or “chip”) is grouped into three phases: design, fabrication and testing. IC design involves the architectural layout of the circuit, as well as design verification and photomask or reticle generation. The fabrication of a chip is accomplished by depositing a series of film layers that act as conductors, semiconductors or insulators. The deposition of these film layers is interspersed with numerous other process steps that create circuit patterns, remove portions of the film layers, and perform

other functions such as heat treatment, measurement and inspection. Most advanced chip designs require over 500 individual steps, many of which are performed multiple times. Most chips consist of two main structures: the lower structure, typically consisting of transistors or capacitors, which perform the “smart” functions of the chip; and the upper structure, typically consisting of “interconnect” circuitry, which connects the components in the lower structure.

When all of the layers on the wafer have been completed, each die on the wafer is then tested for functionality. The wafer is placed on a prober that is used to attach the input/output pins of the device to a tester. When chips are tested on the wafer, it is called sort test. A sort test determines which chips are good. The wafer is then cut up, and the good die are bonded to lead frames that contain pins used to attach the chip to the outside printed circuit board. Wires are bonded from the input/output pads of the IC to the pins of the lead-frame. Then the lead frame is encapsulated in packages typically made of plastic or ceramic materials. The packaged parts are put through a final test and then shipped to customers. This entire packaging and testing process is called the “back end.”

Current Trends

Companies that anticipate future market demands by developing and refining new technologies and manufacturing processes are better positioned to lead in the semiconductor market. During past industry cycles, semiconductor manufacturers generally contended with one key new technology or market trend, such as a specific design rule shrink. In today’s market, the leading semiconductor manufacturers are investing in bringing a multitude of new technologies into production at the same time, including copper interconnects, new substrate and transistor materials, advanced lithography techniques and 300-mm (12-inch) wafers.

While many of these technologies have been adopted at the development and pilot production stages, significant challenges and risks associated with each technology have affected their adoption into full-volume production. For example, as design rules decrease, yields become more sensitive to the size and density of defects, while device performance characteristics (namely speed or capacity) become more sensitive to such parameters as linewidth and film thickness variation. Copper introduces new physical defects, which are harder to find within the interconnect structure, as well as electrical defects, which cannot be detected using conventional optical inspection systems. New process materials, such as low-k dielectrics, silicon-on-insulator (“SOI”) and 193-nm photoresists require extensive characterization before they can be readied for the manufacturing process. Film uniformity is also more difficult to maintain on larger wafers. Moving several of these advanced technologies into production at once only adds to the risks that chipmakers face, since technical challenges in bringing any one of these into production could also slow the adoption of the other technologies.

The focus of our activities has been the development of new process control and yield management tools that enable chipmakers to accelerate the adoption of these new technologies into full-volume production, while minimizing their associated risks. With our portfolio of application-focused technologies and our dedicated yield technology expertise, we are in position to be a key supplier of comprehensive yield management solutions that enable our customers to achieve success for their next-generation products.

The continuing evolution of semiconductor devices to smaller linewidth geometries and more complex multi-level circuitry has significantly increased the cost and performance requirements of the capital equipment used to manufacture these devices. Construction of an advanced wafer fabrication facility today can cost over $3 billion, substantially more than previous generation facilities. As a result, chipmakers are demanding increased productivity and higher returns from their manufacturing equipment. Our process control and yield management equipment enables our customers to better leverage these increasingly expensive facilities and significantly improve their return on investment (“ROI”)—helping them to become low-cost producers.

Our Process Control and Yield Acceleration Solutions

Accelerating the yield ramp and maximizing production yields of high-performance devices are key goals of modern semiconductor manufacturing. Ramping to high-volume production ahead of competitors can

dramatically increase the revenue an IC manufacturer realizes for a given product. KLA-Tencor systems not only

analyze defectivity and metrology issues at critical points in the wafer, photomask and IC manufacturing processes, but also provide information to our customers so that they can identify and address the underlying process problems. The ability to locate the source of defects and characterize process issues enables our customers to improve control over their manufacturing processes, so they can increase their yield of high-performance parts—thus maximizing their profit.

Products

KLA-Tencor operates in one segment for the design, manufacture and marketing of process control and yield management systems for the semiconductor and related microelectronics industry. We design, market, manufacture and sell our equipment—consisting of patterned and unpatterned wafer inspection, optical overlay metrology, electron-beam (e-beam) review, reticle and photomask inspection, spectroscopic, and film and surface measurement tools—as well as our advanced yield analysis and defect classification software to provide fab-wide yield management solutions. These solutions are optimized for the manufacturing process cells used in IC production, including lithography, deposition, etch, and chemical mechanical planarization (CMP). Our offerings can be broadly categorized into four groups: Defect Inspection; Metrology; Services; Software and Other. For our customers manufacturing larger design-rule devices, we provide refurbished KLA-Tencor Certified tools along with warranty and support.

Defect Inspection

KLA-Tencor’s defect inspection tools are used to detect, count, classify and characterize particles, pattern defects, surface anomalies and electrical failures during all stages of the IC manufacturing process, from new product development through yield ramp to baseline yield improvement during volume production. Our portfolio includes the tools that enable our customers to find new defect types during development and ramp, and monitor defect level by type during production. KLA-Tencor defect inspection, review and analysis tools find, identify and locate the source of all types of physical and electrical defects, on all layers.

High-Sensitivity Broadband Brightfield Inspection

As our customers move to 65nm production and begin development of the 45nm node, they face a plethora of new defect types and noise sources as well as a dramatic rise in systematic defects, arising from the adoption of new materials, device structures and lithography techniques. The magnitude of these defect challenges calls for inspection solutions with improved sensitivity and greater range of defect type capture on all layers. In response to these needs, KLA-Tencor unveiled its new 2800™ Series full-spectrum brightfield inspection platform in July 2005. The 2800 features a unique broadband light source spanning deep ultraviolet (DUV), UV and visible wavelengths, and a proprietary optical design that maximizes sensitivity at all throughput settings. This new full-spectrum brightfield inspector has the ability to tune its wavelength to optimize defect capture on each layer. The 2800 Series delivers the high-sensitivity and production-worthy performance that chipmakers need to produce market-leading 65nm devices.

High-Performance Darkfield Inspection

In July 2005, we unveiled the Puma 9000 Series (“Puma”), our latest-generation darkfield inspection platform. Puma represents a marked departure from traditional darkfield tools, which are based on acousto-optical device (“AOD”) scanners and photo-multiplier tube (“PMT”) detectors—technologies that are reaching their limits. Puma replaces the AOD/PMT technology with our patented Streak imaging technology. Scalable for multiple technology generations, Streak combines advanced UV-laser illumination optics with a solid-state, multi-pixel linear sensor to image the scattered light. The result is an inspection system with higher sensitivity at production throughputs than can be achieved with traditional AOD/PMT-based inspection systems. Puma can be configured to accommodate applications ranging from process tool monitoring through critical etch line monitoring, allowing our customers to cost-optimize their inspection strategies and achieve tighter production control.

Electron-Beam Inspection

For advanced IC manufacturing, e-beam inspection is essential—not only during IC development, where the highest sensitivity is needed to root out defects, but also in production, where dedicated systems are required to monitor key process steps. Only e-beam technology can find the smallest physical defects and the subtle electrical defects that plague customers as they introduce new materials and device structures at the 65nm and 45nm nodes. In February 2006, we introduced the latest addition to our eS3x series of e-beam inspection systems—the eS32. A single system spanning development and production applications, the eS32 provides the best sensitivity at throughput for defect types that optical systems cannot find.

Wafer and Film Surface Inspection

All chipmakers extensively utilize inspection tools to detect defects on blanket (unpatterned) films and bare wafer surfaces. In 2004, we unveiled the Surfscan SP2 which incorporates a new UV illumination technology to significantly enhance inspection sensitivity and speed on IC films, as well as both traditional silicon and engineered substrates. Surfscan SP2 is capable of detecting defects as small as 30nm at higher throughputs than those of the previous-generation Surfscan SP1 DLS tool.

Wafer Surface Inspection: The wafer substrate is the foundation of an integrated circuit. Having a defect-free wafer substrate is essential, since defects on the surface of the wafer can adversely affect subsequent semiconductor processes, and ultimately impact IC performance. At the 65nm node and beyond, transistor performance in high-end devices depends critically on the physical and electrical properties of the wafer surface below it. Epitaxial silicon layers and engineered substrates, such as silicon-on-insulator (SOI), have become important substrate materials—with associated challenges. The Surfscan SP2 is the industry standard advanced wafer inspection system, and is being adopted by virtually all wafer manufacturers worldwide to provide critical quality control.

Unpatterned Surface Inspection: IC applications for the Surfscan SP1 and Surfscan SP2 inspectors include not only incoming wafer surface quality measurements, but also process tool qualification and monitoring. Instead of inspecting a patterned wafer, a bare or blanket-film wafer can be used to qualify new process tools, periodically check process tools already in production, or qualify process tools after maintenance.

Advanced fabs require accurate and rapid disposition decision making during manufacturing, as well as quick assessment of tool and process module output. Operators have historically performed this task by visually inspecting a small sample of wafers under a manual or semi-automated light microscope. However, advanced 300mm manufacturing, with large wafer surfaces, smaller device features, and factory automation, challenges the ability of the operator to reliably and repeatably assess the wafer and lot. These conditions place large quantities of valuable wafers at risk.

Viper 2435 is an automated 300mm wafer and tool dispositioning system that captures a broad range of defect types at very high throughput—enabling inspection of 100% of wafer lots. Delivering quick go/no-go decisions, the system enables fab engineers to take corrective action early, when wafers can be reworked or process tool problems can be repaired before additional lots are put at risk. Viper 2435 can be integrated rapidly and seamlessly into a production environment in the lithography, CMP, etch, and films process modules.

Reticle Inspection

Error-free reticles are the first step in ensuring high yields in the manufacturing process, since defects in reticles can be replicated on wafers. Reticles are high-precision quartz plates that contain microscopic images of electronic circuits. Placed into steppers or scanners, these reticles are used to transfer circuit patterns onto wafers to fabricate ICs. The extension of optical lithography below the 130nm node has resulted in the mask error enhancement factor (“MEEF”), where reticle defects once too small to print on the wafer become enhanced in the lithography process to create yield-killing wafer defects.

Table of Contents

In 2003, we introduced TeraScan, a high-resolution inspection system for XRET photomasks, providing a comprehensive mask inspection solution for sub-90nm IC production. TeraScan, along with the revolutionary STARlight system, offers high-sensitivity to detect classical defects (intrusions, extrusions and point defects) as small as 80nm, and CD defects as small as 50nm. TeraScan has the ability to inspect nearly any type of photomask used in IC production, regardless of reticle wavelength and resolution enhancement technology, for sub-90nm design rules.

As IC manufacturing costs and complexities increase with each technology node, ensuring high-yield becomes paramount for today’s wafer fabs. The combination of 193nm lithography and 300mm wafer processing further exacerbates the progressive defects problem because the photomasks must endure longer periods of exposure at higher energy—creating an ideal breeding ground for these contaminants. In addition to finding these elusive defects before they print, reticle inspection techniques must contend with a multitude of new XRET types and the increased packing density of device features associated with 65nm designs.

The industry’s highest resolution contamination mode inspection technology, STARlight-2 was delivered in 2005 on the TeraScan platform. By leveraging platform advances in resolution, along with a detailed understanding of today’s XRET photomasks, STARlight-2 takes the industry-standard STARlight algorithms to the next level. The STARlight-2 algorithms have been especially optimized for the mask re-qualification use case in a wafer fab. STARlight-2 provides early warning on progressive mask defects as well as excellent sensitivity to traditional contamination and ESD. This full-field contamination inspection can handle both single-die and multi-die masks and it covers high-density patterned areas as well as scribes and borders while improving productivity through effective defect categorization using ReviewSmart and Litho3.

Transparent Film and Substrate Inspection

Understanding the optical surface properties of modern materials has become a critical part of manufacturing in industries ranging from microelectronics to biomedicine. With the increasing complexity of manufacturing processes and products comes the need for extremely precise analysis and control of surface properties such as film thickness uniformity, contamination and defectivity, often in real time and online. This trend is paving the way for nondestructive optical metrology techniques to move into volume production environments. Through our acquisition of Candela Instruments during fiscal year 2005, we added the Candela series of Optical Surface Analyzers (“OSA”) to our inspection portfolio. These systems automatically detect and classify surface defects on optoelectronic and semiconductor wafers, including transparent wafers such as sapphire and glass. By simultaneously measuring reflectivity and topographic variations on the surface, these systems enable detection of particles, stains, scratches, pits and bumps. Epi layers and film coatings can also be inspected for uniformity, particles, and surface defects.

Process Window Qualification

Reticles used in the manufacture of today’s advanced ICs incorporate complex resolution enhancement techniques (RETs) that enable lithographers to extend existing lithographic processes to print features smaller than the wavelength of light used—a process called sub-wavelength lithography. These enhancements include OPC and PSM technology, which together reduce the size and fine-tune the shape of features on the wafer. During the photolithography patterning process, marginal RET designs can print as out-of-focus features-or not print at all, creating open circuits that translate to electrical failures within the device. However, since these errors represent design marginalities rather than physical defects on the reticle, they cannot be caught using traditional reticle inspection.

Our Process Window Qualification (“PWQ”) solution enables device manufacturers to identify reticle design marginalities by examining the wafer for poorly printed features using their KLA-Tencor 23xx or 2800 broadband brightfield wafer inspection systems. PWQ enables lithographers to compare die resulting from marginal lithography parameters with die printed under optimized conditions, to identify and prioritize

problematic regions as a function of process parameters. This method enables lithographers to understand the consequences of operating near the boundaries of the process window—allowing more informed decisions about whether to redesign the reticle or fine-tune inline defect and CD monitoring efforts to minimize the impact of the design error on device yield.

Metrology

Metrology is a critical component of detecting, understanding and correcting yield problems. Whether it is verifying that the design will be manufacturable, fully characterizing a new process, or monitoring high-volume manufacturing, our metrology and process window optimization products provide the full range of the critical measurements needed by fabs to manage their manufacturing process. With our unique combination of overlay, critical dimension, and film metrology measurements, IC manufacturers have the capabilities to maintain tight control of their lithography, etch, deposition and CMP processes. This enables them to ramp processes faster and detect process excursions earlier, preventing further material from being processed.

Optical Overlay Metrology

Decreasing linewidths, larger die sizes and increasing chip density all affect the tolerances for layer-to-layer alignment, or overlay, and can result in overlay misregistration errors—a crucial cause of

yield loss. Today’s lithography scanners or steppers require in-line monitoring to insure layer to layer alignment is within spec. These advanced lithography systems also require regular maintenance and performance tests to insure they are meeting the process requirements. Metrology systems are needed to verify scanner or stepper performance after periodic maintenance and to measure alignment between different layers of the semiconductor devices in production to ensure overlay errors are kept within specification.

In fiscal year 2005, we introduced Archer AIM+, our latest overlay metrology solution, which is designed to address chipmakers’ lithography overlay control needs beyond the 65nm node. Archer AIM+ incorporates a new optic system design and improved illumination system to reduce total measurement uncertainty (“TMU”), a key metric of overlay metrology performance and exceed the 45nm node overlay control requirements outlined in the 2005 edition of the International Technology Roadmap for Semiconductors.

In 2006, we introduced the K-T Analyzer lithography correctibles platform to accelerate and improve advanced lithography cell qualification and control. Seamlessly integrated with KLA-Tencor’s Archer overlay metrology platform for 65nm and below IC production, K-T Analyzer provides automated, on-tool analysis of overlay and CD metrology data in real time, giving engineers immediate feedback on the quality of their lithography process. This enables them to correct errors quickly, reduce unnecessary wafer rework, and make efficient use of lithography equipment, thereby ensuring that optimal productivity and tight process control are maintained in the lithography cell. K-T Analyzer is now being used to enhance focus/dose analysis applications at several leading logic and memory manufacturers worldwide.

CD Metrology

Traditional CD linewidth measurements no longer provide all the information that chipmakers need to accurately predict yield and transistor performance. Complete feature profile information is needed, including CD, sidewall angle, height and depth. Contact hole profile measurements are also critical, since contact hole sizes that are significantly reduced or closed at the bottom of the structure can result in significant yield loss.

In February 2006, we introduced the SpectraCD-XT—our fourth-generation of inline optical CD metrology systems for advanced patterning process control at the 90nm and 65nm nodes. SpectraCD-XT is a non-destructive dedicated CD and profile metrology system built on our high-throughput, production-proven Archer platform. The tool is the only high performance spectroscopic ellipsometry (SE)-based

system with sub-2-second move-acquire-measure (“MAM”) time. This performance allows chipmakers to detect even the smallest profile excursions and increase sampling or reduce turn-around-time for critical CD or profile measurements. CD control in the fab is increasingly changing over to Optical CD from traditional CD-SEM metrology tools. We have ceased further development of the CD-SEM metrology tools. SpectraCD-XT further enables this transition with its throughput of greater than 100 wafers per hour, making it the lowest cost of ownership CD tool on the market.

Film Measurement

Our film measurement products measure a variety of optical and electrical properties of thin films. These products are used to control a wide range of wafer fabrication steps, where both within-wafer and wafer-to-wafer process uniformity are of paramount importance to semiconductor manufacturers—enabling them to achieve high device performance characteristics at low cost.

In 2004, we introduced SpectraFx 200, our most advanced, seventh-generation thin-film metrology system, to enable IC manufacturers to achieve cost-effective production control over their advanced film processes at the 65nm node and below. Based on our patented SE technology, SpectraFx 200 utilizes a unique Dielectric Pattern Metrology (“DPM”) capability to provide accurate and robust measurements of in-die process variation on product wafers non-destructively.

Contamination Monitoring

Gate dielectric quality is critical to the speed and reliability of an IC. Below the 90nm node, dielectrics become so thin (less than 20 angstroms, or 2nm) that electrical performance characteristics of the dielectric films become just as critical as physical characteristics in determining overall transistor performance. Our Quantox product line provides non-contact, inline electrical performance measurements of key parameters that determine the quality of advanced gate dielectric films, including contamination and oxide thickness, as well as electrical capacitance and leakage. Our latest Quantox XP system provides information on both the physical and electrical properties of advanced gate dielectric materials, as well as high correlation to device electrical test data, enabling chipmakers to predict transistor performance inline, rather than having to wait until end-of-line electrical test—a process that normally can take days or weeks to complete.

Surface Metrology

Our stylus profilers measure the surface topography of films and etched surfaces, and are used in basic research and development as well as semiconductor production and quality control. The latest generation of our HRP® high resolution profilers, the HRP-340, combines the dishing and erosion measurement capabilities of our long-scan profilers with high-aspect-ratio etched feature measurement capability, which has historically been limited to atomic force microscopes (“AFM”). This allows customers to monitor their critical etch processes, such as shallow trench isolation (“STI”) and dual-damascene via/trench. The P-16 advanced surface profiler is a benchtop contact stylus profiler designed for automated step height, surface contour, and roughness measurements, and provides detailed 2D and 3D analysis of topography for a variety of surfaces and materials. In addition, we also provide stress measurement systems and capabilities, such as our new wafer bow and wafer stress option for our ASET-F5x and SpectraFx 100 thin-film metrology tools, which detects reliability-related problems such as film cracking, voiding and lifting.

Software and Other

Our productivity and analysis solutions translate raw inspection and metrology data into patterns that reveal process problems and help semiconductor manufacturers develop long-term yield improvement strategies. Leveraging our core competencies, KLA-Tencor is also adding value to emerging markets and new high-growth areas. Outside the semiconductor industry, we manufacture, sell and service yield management solutions to the data storage market, with offerings for hard disk drive and component makers.

Yield Management & Analysis Solutions

Klarity Defect® is our automated inline defect analysis module and defect data management system designed to help fabs achieve faster yield learning cycles. By identifying excursions in real time, Klarity Defect enables fabs to embed expert decision-making processes within analysis recipes. These processes are automatically triggered when user-specified events occur. In addition to freeing fab engineers from repetitive analysis tasks, this capability dramatically improves fab operating efficiency by providing relevant information in less time and with less effort for faster identification of yield problems.

Our Klarity ACE yield analysis solution enables fast integration, correlation and analysis of yield- and process-related data to accurately determine the source of defects and process excursions. It can differentiate between random and systematic yield problems, providing users with the data they need in order to take appropriate corrective measures.

In fiscal year 2005, we introduced Klarity SSA (Spatial Signature Analysis), a new capability that provides automated classification and root cause analysis of spatial signatures, which are defect clusters and patterns that can be indicative of an out-of-spec process or process tool problem. Klarity SSA can be utilized for a variety of applications where enhanced excursion detection is needed, including process line and tool monitoring, as well as engineering analysis, across key process modules.

Our ProDATA lithography data analysis tool, along with our PROLITH lithography and etch optimization tool, helps manufacturers reduce their advanced lithography development time and cost, as well as optimize their design-for-manufacturing (“DFM”) efforts.

Our IMPACT XP automated defect classification (“ADC”) solution provides consistent and accurate classification of yield-limiting defects to help our customers accelerate their ramp to higher process yields. IMPACT XP incorporates our SmartGallery tool, which reduces the setup time associated with ADC implementation in fabs. This is a critical requirement, particularly for foundries and application specific integrated circuit (“ASIC”) manufacturers, who specialize in short runs of multiple products. Our Real Time Classification (“RTC”) and iADC technologies, which provide classification and binning of defect types in real time during inspection, are critical features on all of our latest-generation e-beam and optical inspection tools.

Computational Lithography

IC physical designs (layouts) are modified with Reticle Enhancement Techniques (“RET”) and Optical Proximity Correction (“OPC”) to improve the patterning of features from photomask to wafers during lithography. The physical design may include features that are not compatable with today’s sub-wavelength lithography. Also, the RET/OPC models used to apply the modifications may be constrained by the layout. Lastly, the manufacturing process variability of focus and exposure during lithography may also cause

Table of Contents

errors in feature sizing. Such systematc errors can create either open circuits that translate to electrical failures, or speed and power performance issues within the device.

Our DesignScan computational lithography solution enables device manufacturers to comprehensively identify marginal features in the post-OPC mask design data by performing a physics-based simulation of the lithography process (and its variability) followed by an inspection of the results by comparing back to the original layout of the design. The simulation and inspection is performed on our high speed image computing platform which allows for very fast full chip inspections. This enables lithography aware optimization of the final OPC design for the lithography process and its variabilities with the final result of improving yield, and reducing mask manufacturing re-spins for faster time to market.

Data Storage Industry

In the front-end of thin film head wafer manufacturing, we provide the same process control equipment with which we serve the semiconductor industry, with particular strength in photolithography control. In the back-end of head manufacturing, we are the leading provider of a range of test equipment, including fly-height and head resonance testers such as the D6, high-resolution surface profilers, and the MRW3 quasi-static tester. In substrate and media manufacturing, we are the leading provider of metrology and defect inspection solutions with our Candela 6120 system with optical surface analysis technology. Additionally, we are leveraging our expertise in magnetics to meet customers’ challenges in the emerging magnetic random access memory (“MRAM”) market.

Customers

To support our growing, global customer base, we maintain a significant presence throughout the United States, Europe, Asia-Pacific and Japan, staffed with local sales and applications engineers, customer and field service engineers and yield management consultants. We count among our largest customers leading semiconductor manufacturers from each of these regions. In fiscal years 2006, 2005, and 2004, no customer accounted for more than 10% of our total revenues.

Our business depends upon the capital expenditures of semiconductor manufacturers, which in turn depend on the current and anticipated market demand for ICs and products utilizing ICs. We do not consider our business to be seasonal in nature, but it is cyclical with respect to the capital equipment procurement practices of semiconductor manufacturers and it is impacted by the investment patterns of such manufacturers in different global markets. Downturns in the semiconductor industry or slowdowns in the worldwide economy could have a material adverse effect on our future business and financial results.

Sales, Service and Marketing

Our sales, service and marketing efforts are focused on building long-term relationships with our customers. We focus on providing a single and comprehensive resource for the full breadth of process control and yield management products and services. Customers benefit from the simplified planning and coordination, as well as the increased equipment compatibility found when dealing with a single supplier. Our revenues are derived primarily from product sales, mostly through our direct sales force.

We believe that the size and location of our field sales, service and applications engineering, and marketing organizations represent a competitive advantage in our served markets. We have direct sales forces in the United States, Europe, Asia-Pacific and Japan. We maintain an export compliance program that is designed to fully meet the requirements of the United States Departments of Commerce and State.

As of June 30, 2006, we employed over 2,300 sales and related personnel, service engineers and applications engineers. In addition to sales and service offices in the United States, we conduct sales, marketing and services out of wholly-owned subsidiaries or branches of United States subsidiaries in other countries,

including China, France, Germany, India, Israel, Italy, Japan, South Korea, Malaysia, Singapore, Taiwan, Thailand and the United Kingdom. International revenues accounted for approximately 80%, 76%, and 77% of our total revenues in fiscal 2006, 2005, and 2004, respectively. Additional information regarding our revenues from foreign operations for our last three fiscal years can be found in Note 14 to the Consolidated Financial Statements found under Item 8, “Financial Statements and Supplementary Data” in this Annual Report on Form 10-K.

We believe that sales outside the United States will continue to be a significant percentage of our total revenues. Our future performance will depend, in part, on our ability to continue to compete successfully in Asia, one of the largest markets for the sale of yield management services in process monitoring equipment. Our ability to compete in this area is dependent upon the continuation of favorable trading relationships between countries in the region (especially Taiwan, China, Japan and South Korea) and the United States, and our continuing ability to maintain satisfactory relationships with leading semiconductor companies in the region.

International sales and operations may be adversely affected by imposition of governmental controls, restrictions on export technology, political instability, trade restrictions, changes in tariffs and the difficulties associated with staffing and managing international operations. In addition, international sales may be adversely affected by the economic conditions in each country. The revenues from our international business may also be affected by fluctuations in currency exchange rates. Although we attempt to manage the currency risk inherent in non-dollar sales through hedging activities there can be no assurance that such efforts will be adequate. These factors could have a material adverse effect on our future business and financial results.

Backlog

Our backlog for system shipments and associated warranty totaled $999 million and $646 million at June 30, 2006 and 2005, respectively. We include in our backlog only those customer orders for which we have accepted purchase orders and assigned shipment dates within twelve months from the date of order. Orders for service and unreleased products are excluded from the backlog. We expect to fill the present backlog of orders during fiscal year 2007; however, all orders are subject to cancellation or delay by the customer. Due to possible customer changes in delivery schedules or cancellation of orders, our backlog at any particular date is not necessarily indicative of actual sales for any succeeding period.

Research and Development

The market for yield management and process monitoring systems is characterized by rapid technological development and product innovation. These technical innovations are inherently complex and require long development cycles and appropriate professional staffing. We believe that continued and timely development of new products and enhancements to existing products are necessary to maintain our competitive position. Accordingly, we devote a significant portion of our human and financial resources to research and development programs and seek to maintain close relationships with customers to remain responsive to their needs. As part of our customer relationships, we may enter into certain strategic development and engineering programs whereby our customers offset certain of our research and development costs. As of June 30, 2006, we employed approximately 1,200 research and development personnel.

Our key research and development activities during fiscal year 2006 involved development of process control and yield management equipment, especially reticle inspection and advanced wafer inspection for smaller feature sizes, copper-based devices and 300-mm wafers. For information regarding our research and development expenses during the last three fiscal years, including costs offset by our strategic development and engineering programs, see Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this Annual Report on Form 10-K.

Table of Contents

In order to make continuing developments in the semiconductor industry, we are committed to significant engineering efforts toward both product improvement and new product development. New product introductions may contribute to fluctuations in operating results, since customers may defer ordering existing products. If new products have reliability or quality problems, those problems may result in reduced orders, higher manufacturing costs, delays in acceptance of and payment for new products, and additional service and warranty expenses. There can be no assurance that we will successfully develop and manufacture new products, or that new products introduced by us will be accepted in the marketplace. If we do not successfully introduce new products, our results of operations will be adversely affected.

Manufacturing, Raw Materials and Supplies

We perform system design, assembly and testing in-house and utilize an outsourcing strategy for the manufacture of components and major subassemblies. Our in-house manufacturing activities consist primarily of assembling and testing components and subassemblies that are acquired through third-party vendors and integrating those subassemblies into our finished products. Our principal manufacturing activities take place in San Jose and Milpitas, California, with additional operations in San Diego and Hayward, California, Migdal Ha’Emek, Israel and Northtech, Singapore. As of June 30, 2006, we employed approximately 1,000 manufacturing personnel.

Many of the parts, components and subassemblies (collectively “parts”) are standard commercial products, although certain parts are made to our specifications. We use numerous vendors to supply parts for the manufacture and support of our products. Although we make reasonable efforts to ensure that these parts are available from multiple suppliers, this is not always possible and certain parts included in our systems may be obtained only from a single supplier or a limited group of suppliers. We endeavor to minimize the risk of production interruption by selecting and qualifying alternative suppliers for key parts, by monitoring the financial condition of key suppliers, and by ensuring adequate inventories of key parts are available to maintain manufacturing schedules.

Although we seek to reduce our dependence on sole and limited source suppliers, in some cases the partial or complete loss of certain of these sources could disrupt scheduled deliveries to customers, damage customer relationships and have a material adverse effect on our results of operations.

Competition

The worldwide market for process control and yield management systems is highly competitive. In each of our product markets, we face competition from established and potential competitors, some of which may have greater financial, research, engineering, manufacturing and marketing resources than we have, such as Applied Materials, Inc. and Hitachi Electronics Engineering Co., Ltd. We may also face future competition from new market entrants from other overseas and domestic sources. We expect our competitors to continue to improve the design and performance of their current products and processes and to introduce new products and processes with improved price and performance characteristics. We believe that to remain competitive, we will require significant financial resources to offer a broad range of products, to maintain customer service and support centers worldwide, and to invest in product and process research and development.

Significant competitive factors in the market for process control and yield management systems include system performance, ease of use, reliability, installed base and technical service and support. We believe that, while price and delivery are important competitive factors, the customers’ overriding requirement is for systems that easily and effectively incorporate automated and highly accurate inspection and metrology capabilities into their existing manufacturing processes to enhance productivity.

Management believes that we are well positioned in the market with respect to both our products and services. However, any loss of competitive position could negatively impact our prices, customer orders,

 

11


Table of Contents

revenues, gross margins, and market share, any of which would negatively impact our operating results and financial condition.

Acquisitions

We continuously evaluate strategic acquisitions and alliances to expand our technologies, product offerings and distribution capabilities. Acquisitions involve numerous risks, including management issues and costs in connection with integration of the operations, technologies and products of the acquired companies, 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 negatively impact our operating results and financial condition. Additional information regarding business combinations during fiscal year 2006 can be found in Note 6 and Note 16 of the Consolidated Financial Statements found under Item 8, “Financial Statements and Supplementary Data” in this Annual Report on Form 10-K. We acquired all of the shares of ADE Corporation, a supplier of semiconductor process control solutions on October 11, 2006 for a total cash amount of $482 million.

Patents and Other Proprietary Rights

We protect our proprietary technology through reliance on a variety of intellectual property laws, including patent, copyright and trade secret. We have filed and obtained a number of patents in the United States and abroad and intend to continue pursuing the legal protection of our technology through intellectual property laws. In addition, from time to time we acquire license rights under United States and foreign patents and other proprietary rights of third parties.

Although we consider patents and other intellectual property significant to our business, due to the rapid pace of innovation within the process control and yield management systems industry, we believe that our protection through patent and other intellectual property rights is less important than factors such as our technological expertise, continuing development of new systems, market penetration, installed base and the ability to provide comprehensive support and service to customers worldwide.

No assurance can be given that patents will be issued on any of our applications, that license assignments will be made as anticipated, or that our patents, licenses or other proprietary rights will be sufficiently broad to protect our technology. No assurance can be given that any patents issued to or licensed by us will not be challenged, invalidated or circumvented or that the rights granted thereunder will provide us with a competitive advantage. In addition, there can be no assurance that we will be able to protect our technology or that competitors will not be able to independently develop similar or functionally competitive technology.

Employees

As of June 30, 2006, we employed approximately 5,900 people. None of our employees are represented by a labor union. We have not experienced work stoppages and believe that our employee relations are good.

Competition is intense in the recruiting of personnel in the semiconductor and semiconductor equipment industry. We believe that our future success will depend, in part, on our continued ability to hire and retain qualified management, marketing and technical employees.

ITEM 1A. RISK FACTORS

Our operating results and stock price 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 throughout this Annual Report on Form 10-K. Our stock price will continue to be subject to daily variations as well. In addition, our future operating results and stock price may not follow any past trends.

We believe the factors that could make our results fluctuate and difficult to predict include:

 

    our ability to successfully address and resolve all issues arising from the discovery that we had retroactively priced stock options (primarily from July 1, 1997 to June 30, 2002) and had not accounted for them correctly;

 

    the cyclical nature of the semiconductor industry;

 

    global economic uncertainty;

 

    competitive pressure;

 

    our ability to develop and implement new technologies and introduce new products;

 

    our ability to maintain supply of key components;

 

    our ability to manage our manufacturing requirements;

 

    our reliance on services provided by third parties;

 

    our customers’ acceptance and adoption of our new products and technologies;

 

    our ability to protect our intellectual property;

 

    our ability to attract, retain, and replace key employees;

 

    our ability to manage risks associated with acquisitions;

 

    litigation regarding IP and other business matters;

 

    worldwide political instability;

 

    earthquake and other uninsured risks;

 

    our ability to comply with recently enacted and proposed changes in securities laws and regulations;

 

    future changes in accounting and tax standards or practices;

 

    changing regulatory environment;

 

    our exposure to fluctuations in foreign currency exchange rates; and

 

    our ability to successfully modify new systems and guard against computer viruses.

Operating results also could be affected by sudden changes in customer requirements 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.

The discovery that we had retroactively priced stock options (primarily from July 1, 1997 to June 30, 2002) and had not accounted for them correctly has had, and may continue to have, a material adverse effect on our financial results.

We cannot predict the outcome of the pending government inquiries or shareholder lawsuits, and we may face additional government actions, shareholder lawsuits and other legal proceedings related to our historical

stock option practices and the remedial actions we have taken. All of these events have required us, and will continue to require us, to expend significant management time and incur significant accounting, legal, and other expenses. This could divert attention and resources from the operation of our business and adversely affects our financial condition and results of operations.

The Special Committee investigation of our historical stock option practices and resulting restatements has been time consuming and expensive, and has had a material adverse effect on us.

The Special Committee investigation and restatement activities have required us to expend significant management time and incur significant accounting, legal, and other expenses. The resulting restatements have had a material adverse effect on our results of operations. We have recorded additional pre-tax, non-cash, stock-based compensation expense of (a) $348 million for the periods from July 1, 1994 to June 30, 2005 under APB Opinion No. 25 and (b) $22 million for the year ended June 30, 2006 under SFAS No. 123(R). We expect to amortize an additional $6 million of such expenses in future periods. In addition, we have established a Special Litigation Committee to oversee the litigation matters that arose out of the investigation and the restatements and we cannot predict what additional actions may be required by these Committees. The period of time necessary to resolve these follow-up matters is uncertain, and these matters could require significant additional attention and resources.

The ongoing government inquiries relating to our historical stock option practices are time consuming and expensive and could result in injunctions, fines and penalties that may have a material adverse effect on our financial condition and results of operations.

The inquiries by the United States Attorney’s Office for the Northern District of California (“USAO”) and the United States Securities and Exchange Commission (“SEC”) into our historical stock option practices are ongoing. We have fully cooperated with the USAO and the SEC and intend to continue to do so. The period of time necessary to resolve these inquiries is uncertain, and we cannot predict the outcome of these inquiries or whether we will face additional government inquiries, investigations or other actions related to our historical stock option practices. These inquiries will likely require us to continue to expend significant management time and incur significant legal and other expenses, and could result in civil and criminal actions seeking, among other things, injunctions against the Company and the payment of significant fines and penalties by the Company, which may have a material adverse effect on our financial condition, results of operations and cash flow.

We have not been in compliance with SEC reporting requirements and Nasdaq listing requirements and may continue to face compliance issues with both. If we are unable to remain in compliance with SEC reporting requirements and Nasdaq listing requirements, there may be a material adverse effect on the Company and our stockholders.

Due to the Special Committee investigation and resulting restatements, we could not file our periodic reports with the SEC on time and faced the possibility of delisting of our stock from the Nasdaq Global Select Market. With the filing of this Report and our Quarterly Report on Form 10-Q for the quarter ended September 30, 2006, we believe we have returned to full compliance with SEC reporting requirements and Nasdaq listing requirements and, therefore, that the Nasdaq delisting matter is now closed. However, if the SEC has comments on these Reports (or other reports that we previously filed) that require us to file amended reports, or if the Nasdaq Listing Qualifications Panel does not concur that we are in compliance with applicable listing requirements, we may be unable to maintain an effective listing of our stock on a national securities exchange. If this happens, the price of our stock and the ability of our stockholders to trade in our stock could be adversely affected. In addition, we would be subject to a number of restrictions regarding the registration of our stock under federal securities laws, and we would not be able to issue stock options or other equity awards to our employees or allow them to exercise their outstanding options, which could adversely affect our business and results of operations.

Table of Contents

We have been named as a party to a number of shareholder derivative and class action lawsuits relating to our historical stock option practices, and we may be named in additional lawsuits in the future. This litigation could become time consuming and expensive and could result in the payment of significant judgments and settlements, which could have a material adverse effect on our financial condition and results of operations.

In connection with our historical stock option practices and resulting restatements, a number of derivative actions were filed against certain of our current and former directors and officers purporting to assert claims on the Company’s behalf. In addition, a number of securities class action complaints were filed against us and certain of our current and former directors and officers seeking damages related to our historical stock option practices and the resulting investigation, inquiries and restatements. There may be additional lawsuits of this nature filed in the future. We cannot predict the outcome of these lawsuits, nor can we predict the amount of time and expense that will be required to resolve these lawsuits. If these lawsuits become time consuming and expensive, or if there are unfavorable outcomes in any of these cases, there could be a material adverse effect on our business, financial condition and results of operations.

Our insurance coverage will not cover our total liabilities and expenses in these lawsuits, in part because we have a significant deductible on certain aspects of the coverage. In addition, subject to certain limitations, we are obligated to indemnify our current and former directors, officers and employees in connection with the investigation of our historical stock option practices and the related government inquiries and litigation. We currently hold insurance policies for the benefit of our directors and officers, although our insurance coverage may not be sufficient in some or all of these matters. Furthermore, the insurers may seek to deny or limit coverage in some or all of these matters, in which case we may have to self-fund all or a substantial portion of our indemnification obligations.

We are subject to the risks of additional lawsuits in connection with our historical stock option practices, the resulting restatements, and the remedial measures we have taken.

In addition to the possibilities that there may be additional governmental actions and shareholder lawsuits against us, we may be sued or taken to arbitration by former officers and employees in connection with their stock options, employment terminations and other matters. These lawsuits may be time consuming and expensive, and cause further distraction from the operation of our business. The adverse resolution of any specific lawsuit could have a material adverse effect on our business, financial condition and results of operations.

Our efforts to correct past material weaknesses in our internal controls may not have been sufficient, and we may discover additional material weaknesses in our internal controls.

As a result of the Special Committee investigation and our management’s internal review of our historical stock option practices and related matters, we identified past material weaknesses in our internal controls and procedures (see Item 9A—Controls and Procedures). A material weakness is a control deficiency, or combination of them, that results in more than a remote likelihood that a material misstatement in our financial statements will not be prevented or detected. We believe that we have remedied the past material weaknesses in our internal controls and procedures, but there can be no assurance that our corrections were sufficient or fully effective, or that we will not discover additional material weaknesses in our internal controls and procedures in the future.

Failure to maintain effective internal controls may cause us to delay filing our periodic reports with the SEC, affect our Nasdaq listing, and adversely affect our stock price.

The Securities and Exchange Commission, as directed by Section 404 of the Sarbanes-Oxley Act of 2002, adopted rules requiring public companies to include a report of management on internal control over financial reporting in their annual reports on Form 10-K that contain an assessment by management of the effectiveness of

 

15


Table of Contents

the Company’s internal control over financial reporting. In addition, our independent registered public accounting firm must attest to and report on management’s assessment of the effectiveness of the internal control over financial reporting. Although we review our internal control over financial reporting in order to ensure compliance with the Section 404 requirements, if our independent registered public accounting firm is not satisfied with our internal control over financial reporting or the level at which these controls are documented, designed, operated or reviewed, or if the independent registered public accounting firm interprets the requirements, rules and/or regulations differently from our interpretation, then they may decline to attest to management’s assessment or may issue a report that is qualified. This could result in an adverse reaction in the financial marketplace due to a loss of investor confidence in the reliability of our financial statements, which ultimately could negatively impact our stock price.

Federal securities laws, rules and regulations, as well as Nasdaq rules and regulations, require companies to maintain extensive corporate governance measures, impose comprehensive reporting and disclosure requirements, set strict independence and financial expertise standards for audit and other committee members and impose civil and criminal penalties for companies and their chief executive officers, chief financial officers and directors for securities law violations. These laws, rules and regulations have increased and will continue to increase the scope, complexity and cost of our corporate governance, reporting and disclosure practices, which could harm our results of operations and divert management’s attention from business operations.

It may be difficult or costly to obtain director and officer insurance coverage as a result of our stock options problems.

We expect that the issues arising from our previous retroactive pricing of stock options will make it more difficult to obtain director and officer insurance coverage in the future. If we are able to obtain this coverage, it could be significantly more costly than in the past, which would have an adverse effect on our financial results and cash flow. As a result of this and related factors, our directors and officers could face increased risks of personal liability in connection with the performance of their duties. As a result, we may have difficultly attracting and retaining qualified directors and officers, which could adversely affect our business.

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. If we fail to respond to industry cycles, our business could be seriously harmed.

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.

Our business is ultimately driven by the global demand for electronic devices by consumers and businesses. 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. A protracted global economic slowdown may adversely affect our business and results of operations.

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

 

16


Table of Contents

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 or terrorism in regions where we have operations along with 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.

Our future performance depends, in part, upon our ability to continue to compete successfully worldwide.

Our industry includes large manufacturers with substantial resources to support customers 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. 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, including pricing such competitive tools significantly below our product offerings. In addition, we face competition from smaller emerging semiconductor equipment companies whose strategy is to provide a portion of the products and services, similar to what we offer, using innovative technology to sell products into specialized markets. Loss of competitive position could negatively affect our prices, customer orders, revenue, gross margins, and market share, any of which would negatively affect our operating results and financial condition.

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.

Success in the semiconductor equipment industry depends, in part, on continual improvement of existing technologies and rapid innovation of new solutions. For example, in the current semiconductor industry, the size of semiconductor devices continues to shrink and the industry is currently transitioning to the use of new materials and innovative fab processes. 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 staffing of highly qualified employees. 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.

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. 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. 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. 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.

Our business would be harmed if we do not receive sufficient parts to meet our production requirements in a timely and cost-effective manner.

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.

Disruption of our manufacturing facilities due to earthquake, flood, other natural catastrophic events or terrorism could result in cancellation of orders or loss of customers and could seriously harm our business.

Most of our manufacturing facilities are located in the United States, with small operations located in Israel and Singapore. 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.

We outsource a number of services to third-party service providers which decreases our control over the performance of these functions; disruptions or delays at our third-party service providers could adversely impact our operations.

We outsource a number of services including our transportation and logistics management of spare parts to domestic and overseas third-party service providers. While outsourcing arrangements may lower our cost of operations, they also reduce our direct control over the services rendered. It is uncertain what effect such diminished control will have on the quality or quantity of products delivered or services rendered, or our ability to quickly respond to changing market conditions. Disruptions or delays at our third-party service providers due to events such as regional economic, business, environmental, political, or informational technology system failures or military actions could adversely impact our operations and our ability to ship products, manage our product inventory or record and report financial and management information on a timely and accurate basis.

Our success is dependent in part on our technology and other proprietary rights. If we are unable to maintain our lead or protect our proprietary technology, we may lose valuable assets and market share.

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 are 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

 

18


Table of Contents

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.

We might be involved in intellectual property disputes or other intellectual property infringement claims that may be costly to resolve, prevent us from selling or using the challenged technology and seriously harm our operating results and financial condition.

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. 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. Our customary practice is to evaluate such infringement 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, or instigation of litigation or other administrative proceedings could seriously harm our operating results and financial condition.

We depend on key personnel to manage our business effectively and if we are unable to attract, retain, and motivate our key employees, our sales and product development could be harmed.

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.

We have made and we expect to continue to make acquisitions that could cause diversion of company’s resources and our operating results could be harmed.

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.

We are predominantly uninsured for losses and interruptions caused by terrorist acts and acts of war. If international political instability continues or increases, our business and results of operation could be harmed.

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. Any act of terrorism which affects the economy or the semiconductor industry could adversely affect our business. Increased international political instability, disruption in air transportation and further enhanced security measures as a result of 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. We are predominantly uninsured for losses and interruptions caused by terrorist acts and acts of war.

We self insure certain risks including earthquake risk. If one or more of the uninsured events occurs, we could suffer major financial loss.

We purchase insurance to help mitigate the economic impact of certain insurable risks; however, certain other risks are uninsurable or are insurable only at significant costs and cannot be mitigated with insurance. An earthquake could significantly disrupt our manufacturing operations, most of which are conducted in California. It could also significantly delay our research and engineering effort on new products, most of which is also conducted in California. We take steps to minimize the damage that would be caused by an earthquake, but there is no certainty that our efforts will prove successful in the event of an earthquake. We self insure earthquake risks because we believe this is the prudent financial decision based on our large cash reserves and the high cost and limited coverage available in the earthquake insurance market. Certain other risks are also self insured either based on a similar cost benefit analysis, or based on the unavailability of insurance. If one or more of the uninsured events occurs, we could suffer major financial loss.

A change in accounting standards or practices or a change in existing taxation rules or practices can have a significant effect on our reported results and may even affect reporting of transactions completed before the change is effective.

New accounting pronouncements and taxation rules and varying interpretations of accounting pronouncements and taxation practice have occurred and may occur in the future. Changes to existing rules or the questioning of current practices may adversely affect our reported financial results or the way we conduct our business.

For example, the adoption of Statement of Financial Accounting Standards (“SFAS”) No. 123(R), which required us to measure all employee stock-based compensation awards using a fair value method beginning in fiscal year 2006 and record such expense in our consolidated financial statements had a material impact on our consolidated financial statements, as reported under accounting principles generally accepted in the United States of America.

We are exposed to various risks related to the regulatory environments where we perform our operation and conduct our business.

We are subject to various risks related to new, different, inconsistent or even conflicting laws, rules and regulations that may be enacted by legislative bodies and/or regulatory agencies in the countries in which we operate and with which we must comply including environmental and safety regulations.

We are exposed to foreign currency exchange rate fluctuations; although we hedge certain currency risks, we may still be adversely affected by changes in foreign currency exchange rates or declining economic conditions in these countries.

We have some exposure to fluctuations in foreign currency exchange rates, primarily the Japanese Yen. We have international subsidiaries that operate and sell our products globally. We routinely hedge these exposures in an effort to minimize the impact of currency rate fluctuations, but these hedges may be inadequate to protect us from currency rate fluctuations. To the extent that these hedges are inadequate, our reported financial results or the way we conduct our business could be adversely affected.

We are exposed to fluctuations in the market values of our portfolio investments and in interest rates; impairment of our investments could harm our earnings.

Our investment portfolio consists of both corporate and government securities that have a maximum maturity of 10 years. The longer the duration of these securities, the more susceptible they are to changes in

 

20


Table of Contents

market interest rates and bond yields. As yields increase, those securities with a lower yield-at-cost show a mark-to-market unrealized loss. All unrealized losses are due to changes in interest rates and bond yields. We have the ability to realize the full value of all these investments upon maturity.

We rely upon certain critical information systems for our daily business operation, our inability to use or access these information systems at critical points in time could unfavorably impact the timeliness and efficiency of our business operation.

Our global operations are linked by information systems, including telecommunications, the internet, our corporate intranet, network communications, email and various computer hardware and software applications. Despite our implementation of network security measures, our tools and servers are vulnerable to computer viruses, break-ins, and similar disruptions from unauthorized tampering with our computer systems and tools located at customer sites. Any such event could have an adverse effect on our business, operating results, and financial condition.

Acquisitions are an important element of our strategy but, because of the uncertainties involved, we may not find suitable acquisition candidates and we may not be able to successfully integrate and manage acquired businesses.

Part of our growth strategy is to pursue acquisitions. There can be no assurance that we will find suitable acquisition candidates or that acquisitions we complete will be successful. In addition, we may use equity to finance future acquisitions, which would increase our number of shares outstanding and be dilutive to current shareholders.

If we are unable to successfully integrate and manage acquired businesses or if acquired businesses perform poorly, then our business and financial results may suffer. It is possible that the businesses we have acquired, such as ADE Corporation, which we acquired on October 11, 2006, as well as businesses that we may acquire in the future, may perform worse than expected or prove to be more difficult to integrate and manage than expected. If that happens, there may be a material adverse effect on our business and financial results for a number of reasons, including:

 

    we may have to devote unanticipated financial and management resources to acquired businesses;

 

    we may not be able to realize expected operating efficiencies or product integration benefits from our acquisitions;

 

    we may have to write-off goodwill or other intangible assets; and

 

    we may incur unforeseen obligations or liabilities in connection with acquisitions.

We may experience difficulties with our enterprise resource planning (“ERP”) system and other IT systems. System failure or malfunctioning may result in disruption of operations and the inability to process transactions, and this could adversely affect our financial results.

System failure or malfunctioning could disrupt our ability to timely and accurately process and report key components of the results of our consolidated operations, our financial position and cash flows. Any disruptions or difficulties that may occur in connection with our ERP system or other systems could also adversely affect our ability to complete important business processes such as the evaluation of our internal controls and attestation activities pursuant to Section 404 of the Sarbanes-Oxley Act of 2002. If we encounter unforeseen problems with regard to our ERP system or other systems, our business could be adversely affected.

ITEM 3. LEGAL PROCEEDINGS

Special Committee Investigation of Historical Stock Option Practices

On May 22, 2006, the Wall Street Journal published an article about stock option backdating that questioned the stock option practices at several companies, including KLA-Tencor. On May 23, 2006, we received a subpoena from the United States Attorney’s Office for the Northern District of California (“USAO”) and a letter of inquiry from the United States Securities and Exchange Commission (“SEC”) regarding our stock option practices. Later on May 23, 2006, our Board of Directors appointed a Special Committee composed solely of independent directors to conduct a comprehensive investigation of our historical stock option practices. The Special Committee promptly engaged independent legal counsel and accounting experts to assist with the investigation. The investigation included an extensive review of our historical stock option practices, accounting policies, accounting records, supporting documentation, email communications and other documentation, as well as interviews of a number of current and former directors, officers and employees. On September 27, 2006, the Special Committee reported the bulk of its findings and recommendations to our Board of Directors.

Findings and Remedial Actions

On September 28, 2006, we announced that we would have to restate our previously issued financial statements to correct our past accounting for stock options. As a result of the Special Committee investigation, we discovered that certain of our stock options, primarily those granted from July 1, 1997 to June 30, 2002, had been retroactively priced for all employees who received these grants. This means that the option exercise price was not the market price of the option shares on the actual grant date of the option, but instead was a lower market price on an earlier date. The actual grant date—when the essential actions necessary to grant the option were completed, including the final determination of the number of shares to be granted to each employee and the exercise price—is the correct measurement date to determine the market price of the option shares under the accounting rules in effect at the time. More than 95% of the total in-the-money value (market price on the actual grant date minus exercise price) of all of our retroactively priced options was attributable to those granted from July 1, 1997 to June 30, 2002.

We previously applied Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees,” and its related Interpretations and provided the required pro forma disclosures under Statement of

 

23


Table of Contents

Financial Accounting Standards (“SFAS”) No. 123, “Accounting for Stock-Based Compensation,” through our fiscal year ended June 30, 2005. Under APB Opinion No. 25, a non-cash, stock-based compensation expense was required to be recognized for any option for which the exercise price was below the market price on the actual grant date. Because each of our retroactively priced options had an exercise price below the market price on the actual grant date, there should have been a non-cash charge for each of these options under APB Opinion No. 25 equal to the number of option shares, multiplied by the difference between the exercise price and the market price on the actual grant date. That expense should have been amortized over the vesting period of the option. Starting in our fiscal year ended June 30, 2006, we adopted SFAS No. 123(R), “Share-Based Payment.” As a result, beginning in fiscal year 2006, the additional stock-based compensation expense required to be recorded for each retroactively priced option is equal to the incremental fair value of the option on the actual grant date, amortized over the remaining vesting period of the option. We did not record these stock-based compensation expenses under APB Opinion No. 25 or SFAS No. 123(R) related to our retroactively priced options in our previously issued financial statements, and that is why we are restating them in this filing. To correct our past accounting for stock options, we recorded additional pre-tax, non-cash, stock-based compensation expense of (a) $348 million for the periods July 1, 1994 to June 30, 2005 under APB Opinion No. 25 and (b) $22 million for the year ended June 30, 2006 under SFAS No. 123(R). We expect to amortize an additional $6 million of such pre-tax charges under SFAS No. 123(R) in future periods to properly account for past retroactively priced stock options.

By October 16, 2006, the Special Committee had substantially completed its investigation. The Special Committee concluded that (1) there was retroactive pricing of stock options granted to all employees who received options, primarily during the periods from July 1, 1997 to June 30, 2002 (less than 15% of these options were granted to executive officers), (2) the retroactively priced options were not accounted for correctly in our previously issued financial statements, (3) the retroactive pricing of options was intentional, not inadvertent or through administrative error, (4) the retroactive pricing of options involved the selection of fortuitously low exercise prices by certain former executive officers, and other former executives may have been aware of this conduct, (5) the retroactive pricing of options involved the falsification of Company records, resulting in erroneous statements being made in financial and other reports previously filed with the SEC, as well as in information previously provided to our independent registered public accounting firm, and (6) in most instances, the retroactive pricing of options violated the terms of our stock option plans. Because virtually all holders of retroactively priced options issued by the Company were not involved in or aware of the retroactive pricing, the Board of Directors decided that we should continue to honor the options that violated the terms of our stock option plans, except in certain individual cases as described below.

The Special Committee concluded that, with a few immaterial exceptions, the retroactive pricing of stock options stopped after June 30, 2002. After that time, there were procedures in place designed to provide reasonable assurance that stock options were priced on the grant date. The Special Committee also concluded that none of our independent Directors was involved in or aware of the retroactive pricing of stock options. Based on the Special Committee’s report, our Board of Directors concluded that no current members of management were involved in the retroactive pricing of stock options. During its investigation of our historical stock option practices, the Special Committee did not find evidence of any other financial reporting or accounting issues.

As a result of the Special Committee investigation, on October 16, 2006, we terminated our employment relationship and agreement with Kenneth L. Schroeder, and we announced our intent to cancel all outstanding stock options held by Mr. Schroeder that were retroactively priced or otherwise improperly granted. Those options were canceled in December 2006. Mr. Schroeder was the Company’s Chief Executive Officer and a member of its Board of Directors from mid-1999 until January 1, 2006, and was a member of the Company’s stock option committee from 1994 until December 31, 2005. From January 1, 2006 to October 16, 2006, Mr. Schroeder was employed as a Senior Advisor to the Company. On November 10, 2006, Mr. Schroeder’s counsel informed us that Mr. Schroeder contests our right to terminate his employment relationship and agreement and to cancel any of his options. We intend to vigorously defend any claims that may be made by Mr. Schroeder regarding these matters, which could involve a material amount.

Also on October 16, 2006, Stuart J. Nichols, Vice President and General Counsel, resigned. Mr. Nichols and we entered into a Separation Agreement and General Release under which Mr. Nichols’ outstanding retroactively priced stock options have been re-priced by increasing the exercise price to the market price of the option shares on the actual grant date. Under SFAS No. 123(R), no incremental charge will be recognized in the financial statements for the quarter ended December 31, 2006.

On October 16, 2006, Kenneth Levy, Founder and Chairman of the Board of Directors of the Company, retired as a director and employee, and was named Chairman Emeritus by our Board of Directors. Mr. Levy and we entered into a Separation Agreement and General Release under which Mr. Levy’s outstanding retroactively priced stock options have been re-priced by increasing the exercise price to the market price of the option shares on the actual grant date. Under SFAS No. 123(R), no incremental charge will be recognized in the financial statements for the quarter ended December 31, 2006. Mr. Levy was the Company’s Chief Executive Officer from 1975 until mid-1999 (with the exception of mid-1997 to mid-1998), was a member of the Company’s Board of Directors from 1975 until his retirement, was Chairman of the Board of Directors from 1999 until his retirement, and was a member of the Company’s stock option committee from 1994 until use of that committee was suspended in the fall of 2006.

On December 21, 2006, Jon D. Tompkins resigned as a director of the Company, and we agreed to modify the outstanding options held by Mr. Tompkins (all of which were fully vested) to extend the post-termination exercisability period to December 31, 2007, which is the last day of the calendar year in which those options would have terminated in the absence of such extension. Mr. Tompkins, the Chief Executive Officer of Tencor Instruments before its merger into the Company in mid-1997, was the Company’s Chief Executive Officer from mid-1997 to mid-1998, was a member of the Company’s stock option committee from mid-1997 until mid-1999, and was a member of the Company’s Board of Directors from mid-1997 until his resignation.

Although the Board of Directors concluded that John H. Kispert, our President and Chief Operating Officer, was not involved in and was not aware of the improper stock option practices, based on the Special Committee’s recommendation, his outstanding retroactively priced options have been re-priced because he served as Chief Financial Officer during part of the period in question. This re-pricing involved increasing the exercise price to the market price of the option shares on the actual grant date. Under SFAS No. 123(R), no incremental charge will be recognized in the financial statements for the quarter ended December 31, 2006.

After the Special Committee substantially completed its investigation, a number of follow-up activities continued, especially in connection with the preparation of this Annual Report on Form 10-K and our Quarterly Report on Form 10-Q for the quarter ended September 30, 2006. The Special Committee also continues to assist the Company in connection with the government inquiries described below. Additional follow-up activities may be required.

Government Inquiries Relating to Historical Stock Option Practices

On May 23, 2006, we received a subpoena from the USAO requesting information relating to our past stock option grants and related accounting matters. Also on May 23, 2006, we received a letter from the SEC making an informal inquiry and request for information on the same subject matters. We are cooperating fully with the USAO and SEC inquiries and intend to continue to do so. These inquiries likely will require us to expend significant management time and incur significant legal and other expenses, and could result in civil and criminal actions seeking, among other things, injunctions against the Company and the payment of significant fines and penalties by the Company, which may adversely affect our results of operations and cash flow.

We have also responded to inquiries from the U.S. Department of Labor, which is conducting an examination of our 401(k) Savings Plan. We are cooperating fully with this examination and intend to continue to do so.

We cannot predict how long it will take to or how much more time and resources we will have to expend to resolve these government inquiries, nor can we predict the outcome of these inquiries. Also, there can be no assurance that other inquiries, investigations or actions will not be started by other United States federal or state regulatory agencies or by foreign governmental agencies.

Late SEC Filings and Nasdaq Delisting Proceedings

Due to the Special Committee investigation and the resulting restatements, we did not file on time this Annual Report on Form 10-K and our Quarterly Report on Form 10-Q for the quarter ended September 30, 2006. As a result, we received two Nasdaq Staff Determination letters, dated September 14, 2006 and November 14, 2006, respectively, stating that we were not in compliance with the filing requirements of Marketplace Rule 4310(c)(14) and, therefore, that our stock was subject to delisting from the Nasdaq Global Select Market. We appealed this determination and requested a hearing before a Nasdaq Listing Qualifications Panel. On October 26, 2006, we attended a hearing, at which we sought appropriate exceptions to the filing requirements from the Panel pending completion and filing of our delinquent reports. On January 3, 2007, the Panel granted our request for continued listing of our stock on the Nasdaq Global Select Market, subject to the condition that we file this Report and our Quarterly Report on Form 10-Q for the quarter ended September 30, 2006 on or before January 31, 2007.

With the filing of this Report and our Quarterly Report on Form 10-Q for the quarter ended September 30, 2006, we believe we have returned to full compliance with SEC reporting requirements and Nasdaq listing requirements, and, therefore, that the Nasdaq delisting matter is now closed. However, we cannot predict whether the SEC will review these Reports and, if so, whether the SEC will have comments on these Reports (or other reports that we previously filed) that may require us to file amended reports with the SEC. In addition, we cannot predict whether the Nasdaq Listing Qualifications Panel will concur that we are in compliance with all relevant listing requirements. If either of those events occurs, we might be unable to remain in compliance with SEC reporting requirements and Nasdaq listing requirements, and, therefore, we might be unable to maintain an effective listing of our common stock on the Nasdaq Global Select Market or any other national securities exchange.

Shareholder Derivative Litigation Relating to Historical Stock Option Practices

Beginning on May 22, 2006, several persons and entities identifying themselves as shareholders of KLA-Tencor filed derivative actions purporting to assert claims on behalf of and in the name of the Company against various of our current and former directors and officers relating to our accounting for stock options issued from 1994 to the present. The complaints in these actions allege that the individual defendants breached their fiduciary duties and other obligations to the Company and violated state and federal securities laws in connection with our historical stock option granting process, our accounting for past stock options, and historical sales of stock by the individual defendants. Three substantially similar actions are pending, one in the U.S. District Court for the Northern District of California (which consists of three separate lawsuits consolidated in one action); one in the California Superior Court for Santa Clara County; and one in the Delaware Chancery Court.

The plaintiffs in the derivative actions have asserted claims for violations of Sections 10(b) (including Rule 10b-5 thereunder), 14(a), and 20(a) of the Securities Exchange Act of 1934, unjust enrichment, breach of fiduciary duty and aiding and abetting such breach, negligence, misappropriation of information, abuse of control, gross mismanagement, waste of corporate assets, breach of contract, constructive fraud, rescission, and violations of California Corporations Code section 25402, as well as a claim for an accounting of all stock option grants made to the named defendants. KLA-Tencor is named as a nominal defendant in these actions. On behalf of KLA-Tencor, the plaintiffs seek unspecified monetary and other relief against the named defendants. The plaintiffs are James Ziolkowski, Mark Ziering, Alaska Electrical Pension Fund, Jeffrey Rabin, and Benjamin Langford. The individual named defendants are current directors and officers; Edward W. Barnholt, H. Raymond Bingham, Robert T. Bond, Jeffrey L. Hall, Stephen P. Kaufman, John H. Kispert, Lida Urbanek and Richard P. Wallace; and former directors and officers; Robert J. Boehlke, Leo Chamberlain, Gary E. Dickerson, Richard J. Elkus, Jr., Dennis J. Fortino, Kenneth Levy, Michael E. Marks, Stuart J. Nichols, Arthur P. Schnitzer, Kenneth L. Schroeder and Jon D. Tompkins. Current director David C. Wang and former director Dean O. Morton were originally named as defendants in one of the derivative actions filed in the U.S. District Court for the Northern District of California, but were dropped as named defendants as of December 22, 2006 upon the filing of a consolidated complaint in that action.

Table of Contents

The derivative actions are at an early stage. Discovery has not commenced, and the defendants are not yet required to respond to the complaints. Our Board of Directors has appointed a Special Litigation Committee (“SLC”) composed solely of independent directors to conduct an independent investigation of the claims asserted in the derivative actions and to determine the Company’s position with respect to those claims. The SLC’s investigation is in progress. We cannot predict whether these actions are likely to result in any material recovery by or expense to KLA-Tencor.

Shareholder Class Action Litigation Relating to Historical Stock Option Practices

KLA-Tencor and various of our current and former directors and officers were named as defendants in a putative securities class action filed on June 29, 2006 in the U.S. District Court for the Northern District of California. Two similar actions were filed later in the same court, and all three cases have been consolidated into one action. The complaints allege claims under the Securities Exchange Act of 1934 as a result of our past stock option grants and related accounting and reporting, and seek unspecified monetary damages and other relief. The plaintiffs seek to represent a class consisting of purchasers of KLA-Tencor stock between February 13, 2001 and May 22, 2006 who allegedly suffered losses as a result of material misrepresentations in KLA-Tencor’s SEC filings during that period. The lead plaintiffs, who seek to represent the class, are the Police and Fire Retirement System of the City of Detroit, the Louisiana Municipal Police Employees’ Retirement System, and the City of Philadelphia Board of Pensions and Retirement. The defendants are KLA-Tencor, Edward W. Barnholt, H. Raymond Bingham, Robert J. Boehlke, Robert T. Bond, Gary E. Dickerson, Richard J. Elkus, Jr., Jeffrey L. Hall, Stephen P. Kaufman, John H. Kispert, Kenneth Levy, Michael E. Marks, Kenneth L. Schroeder, Jon D. Tompkins, Lida Urbanek and Richard P. Wallace.

This litigation is at an early stage. Discovery has not commenced, the court has not yet determined whether the plaintiffs may sue on behalf of any class of purchasers, and the defendants are not yet required to respond to the complaints. The Company intends to vigorously defend this litigation.

As part of a derivative lawsuit filed in the Delaware Chancery Court on July 21, 2006 (described above), a plaintiff claiming to be a KLA-Tencor shareholder also asserted a separate putative class action claim against KLA-Tencor and certain of our current and former directors and officers alleging that shareholders incurred damage due to purported dilution of KLA-Tencor common stock resulting from historical stock option granting practices. The Company intends to vigorously defend this litigation.

We cannot predict the outcome of the shareholder class action cases (described above), and we cannot estimate the likelihood or potential dollar amount of any adverse results. However, an unfavorable outcome in this litigation could have a material adverse impact upon our financial position, results of operations or cash flows for the period in which the outcome occurs and in future periods.

Indemnification Obligations

Subject to certain limitations, we are obligated to indemnify our current and former directors, officers and employees in connection with the investigation of our historical stock option practices and related government inquiries and litigation. 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 in connection with these matters. We are currently paying or reimbursing legal expenses being incurred in connection with these matters by a number of our current and former directors, officers and employees. Although the maximum potential amount of future payments KLA-Tencor could be required to make under these agreements is theoretically unlimited, the Company believes the fair value of this liability is adequately covered within the reserves it has established for currently pending legal proceedings.

Other Legal Matters

We are named from time to time as a party to lawsuits in the normal course of our business. Litigation in general, and intellectual property and securities litigation in particular, can be expensive and disruptive to normal business operations. Moreover, the results of legal proceedings are difficult to predict.

ITEM 5. MARKET FOR THE REGISTRANT’S COMMON STOCK, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Our common stock is listed and traded on the Nasdaq Global Select Market under the symbol “KLAC.”

Due to the Special Committee investigation of our historical stock option practices (see Item 3—Legal Proceedings) and the resulting restatements (see Note 2, “Restatements of Consolidated Financial Statements and Special Committee and Company Findings,” to Consolidated Financial Statements), we did not file our periodic reports with the SEC on time and therefore the Company’s stock was subject to delisting from the Nasdaq Global Select Market. With the filing of this Report and our Quarterly Report on Form 10-Q for the quarter ended September 30, 2006, we believe we have returned to full compliance with SEC reporting requirements and Nasdaq listing requirements and, therefore, that the Nasdaq delisting matter is now closed. (See Item 1A—Risk Factors)

The prices per share reflected in the following table represent the high and low closing prices for our common stock on the Nasdaq Global Select Market for the periods indicated.

During the fourth quarter of fiscal year 2006, the Company’s Board of Directors authorized a quarterly cash dividend of $0.12 per share. The total amount of dividends paid during the year ended June 30, 2006 was $95.3 million. During the first quarter of fiscal year 2007, the Company’s Board of Directors authorized a quarterly cash dividend of $0.12 per share, which was declared on August 3, 2006 and paid on September 1, 2006 to our stockholders of record on August 15, 2006. During the second quarter of fiscal year 2007, the Company’s Board of Directors authorized a quarterly cash dividend of $0.12 per share, which was declared on November 6, 2006 and was paid on December 1, 2006 to our stockholders of record on November 15, 2006.

(1) In July 1997, the Board of Directors authorized KLA-Tencor to systematically repurchase up to 17.8 million shares of its common stock in the open market. This program was put into place in order to reduce the dilution that results from KLA-Tencor’s issuance of its shares pursuant to its employee benefit and incentive plans such as the stock option and employee stock purchase plans. From the inception of the repurchase program in 1997 through June 30, 2006 the Board of Directors has authorized KLA-Tencor to repurchase a total of 27.8 million shares. All such repurchased shares remain as treasury shares and are retired.
(2) All shares were purchased pursuant to the program publicly announced in July 1997 and as extended by the Board of Directors most recently in February 2005 by an additional 10.0 million shares.
(3) The stock repurchase program has no expiration date. Our systematic buyback program was suspended in May 2006. We intend to recommence purchases under the stock repurchase program when we have returned to full compliance with the filing of the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2006 and Quarterly Report on Form 10-Q for the quarter ended September 30, 2006.

Effective in fiscal year 2006, we implemented Statement of Financial Accounting Standards (“SFAS”) No. 123(R) “Share-Based Payment.” It requires us to measure all employee stock-based compensation awards using a fair value method and record such expense in our consolidated financial statements. In addition, to correct our past accounting for retroactively priced stock options, granted primarily from July 1, 1997 to June 30, 2002, we recorded an aggregate of $348 million of additional pre-tax, non-cash, stock-based compensation expense ($230 million net of tax), for the periods July 1, 1994 to June 30, 2005 under APB No. 25. Also, we recorded an aggregate of $22 million of additional pre-tax, non-cash, stock-based compensation expense ($10 million net of tax) for the year ended June 30, 2006 under SFAS No. 123(R). The net income in fiscal year 2006 includes approximately $106 million of non-cash, stock-based compensation expense, compared to $25 million in fiscal year 2005, $31 million in fiscal year 2004, $47 million in fiscal year 2003 and $52 million in fiscal year 2002.

In addition, we have made other adjustments totaling $1 million net of tax for the periods July 1, 1994 to June 30, 2005 to record unadjusted differences identified in prior years that were not material to our previously filed financial statements as well as adjustments to correct the classification of certain amounts presented as cash and cash equivalents and marketable securities related to investments in Variable Rate Demand Notes.

Table of Contents

Diluted shares in fiscal years 2002 to 2005 increased as a result of the restatement adjustments to correct our past accounting for stock options that were retroactively priced. We use the treasury stock method to calculate the weighted-average shares used in the diluted earnings per share calculation. As part of the restatement, we revised our treasury stock calculations in accordance with SFAS No. 128, “Earnings Per Share.” These calculations assume that (i) all retroactively priced options are exercised, (ii) we repurchase shares with the proceeds of these hypothetical exercises along with the tax benefit resulting from the hypothetical exercises, and (iii) any unamortized deferred stock-based compensation is also used to repurchase shares.

Consolidated working capital as of June 30, 2005, 2004, 2003 and 2002 has been adjusted primarily as a result of the restatements to correct our past accounting for stock options. These adjustments primarily affect deferred tax assets and tax liabilities.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion of our financial condition and results of operations should be read in conjunction with our Consolidated Financial Statements and the related notes included in Item 8, “Financial Statements and Supplementary Data,” in this Annual Report on Form 10-K. This discussion contains forward-looking statements, which involve risk and uncertainties. Our actual results could differ materially from those anticipated in the forward-looking statements as a result of certain factors, including but not limited to those discussed in “Item 1A. Risk Factors” and elsewhere in this Annual Report on Form 10-K. (See “Special Note Regarding Forward-Looking Statements.”)

Restatements of Consolidated Financial Statements and Special Committee and Company Findings

Special Committee Investigation of Historical Stock Option Practices

On May 22, 2006, the Wall Street Journal published an article about stock option backdating that questioned the stock option practices at several companies, including KLA-Tencor. On May 23, 2006, we received a subpoena from the United States Attorney’s Office for the Northern District of California (“USAO”) and a letter of inquiry from the United States Securities and Exchange Commission (“SEC”) regarding our stock option practices. Later on May 23, 2006, our Board of Directors appointed a Special Committee composed solely of independent directors to conduct a comprehensive investigation of our historical stock option practices. The Special Committee promptly engaged independent legal counsel and accounting experts to assist with the investigation. The investigation included an extensive review of our historical stock option practices, accounting policies, accounting records, supporting documentation, email communications and other documentation, as well as interviews of a number of current and former directors, officers and employees. On September 27, 2006, the Special Committee reported the bulk of its findings and recommendations to our Board of Directors.

Findings and Remedial Actions

On September 28, 2006, we announced that we would have to restate our previously issued financial statements to correct our past accounting for stock options. As a result of the Special Committee investigation, we discovered that certain of our stock options, primarily those granted from July 1, 1997 to June 30, 2002, had been retroactively priced for all employees who received these grants. This means that the option exercise price was not the market price of the option shares on the actual grant date of the option, but instead was a lower market price on an earlier date. The actual grant date—when the essential actions necessary to grant the option were completed, including the final determination of the number of shares to be granted to each employee and the exercise price—is the correct measurement date to determine the market price of the option shares under the accounting rules in effect at the time. More than 95% of the total in-the-money value (market price on the actual grant date minus exercise price) of all of our retroactively priced options was attributable to those granted from July 1, 1997 to June 30, 2002.

We previously applied Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees,” and its related Interpretations and provided the required pro forma disclosures under Statement of Financial Accounting Standards (“SFAS”) No. 123, “Accounting for Stock-Based Compensation,” through our fiscal year ended June 30, 2005. Under APB Opinion No. 25, a non-cash, stock-based compensation expense was required to be recognized for any option for which the exercise price was below the market price on the actual grant date. Because each of our retroactively priced options had an exercise price below the market price on the actual grant date, there should have been a non-cash charge for each of these options under APB Opinion No. 25 equal to the number of option shares, multiplied by the difference between the exercise price and the market price on the actual grant date. That expense should have been amortized over the vesting period of the option. Starting in our fiscal year ended June 30, 2006, we adopted SFAS No. 123(R), “Share-Based Payment.” As a result, beginning in fiscal year 2006, the additional stock-based compensation expense required to be recorded for each retroactively priced option is equal to the incremental fair value of the option on the actual grant date,

amortized over the remaining vesting period of the option. We did not record these stock-based compensation expenses under APB Opinion No. 25 or SFAS No. 123(R) related to our retroactively priced options in our previously issued financial statements, and that is why we are restating them in this filing. To correct our past accounting for stock options, we recorded additional pre-tax, non-cash, stock-based compensation expense of (a) $348 million for the periods July 1, 1994 to June 30, 2005 under APB Opinion No. 25 and (b) $22 million for the year ended June 30, 2006 under SFAS No. 123(R). We expect to amortize an additional $6 million of such pre-tax charges under SFAS No. 123(R) in future periods to properly account for past retroactively priced stock options.

By October 16, 2006, the Special Committee had substantially completed its investigation. The Special Committee concluded that (1) there was retroactive pricing of stock options granted to all employees who received options, primarily during the periods from July 1, 1997 to June 30, 2002 (less than 15% of these options were granted to executive officers), (2) the retroactively priced options were not accounted for correctly in our previously issued financial statements, (3) the retroactive pricing of options was intentional, not inadvertent or through administrative error, (4) the retroactive pricing of options involved the selection of fortuitously low exercise prices by certain former executive officers, and other former executives may have been aware of this conduct, (5) the retroactive pricing of options involved the falsification of Company records, resulting in erroneous statements being made in financial and other reports previously filed with the SEC, as well as in information previously provided to our independent registered public accounting firm, and (6) in most instances, the retroactive pricing of options violated the terms of our stock option plans. Because virtually all holders of retroactively priced options issued by the Company were not involved in or aware of the retroactive pricing, the Board of Directors decided that we should continue to honor the options that violated the terms of our stock option plans, except in certain individual cases as described below.

The Special Committee concluded that, with a few immaterial exceptions, the retroactive pricing of stock options stopped after June 30, 2002. After that time, there were procedures in place designed to provide reasonable assurance that stock options were priced on the grant date. The Special Committee also concluded that none of our independent Directors was involved in or aware of the retroactive pricing of stock options. Based on the Special Committee’s report, our Board of Directors concluded that no current members of management were involved in the retroactive pricing of stock options. During its investigation of our historical stock option practices, the Special Committee did not find evidence of any other financial reporting or accounting issues.

As a result of the Special Committee investigation, on October 16, 2006, we terminated our employment relationship and agreement with Kenneth L. Schroeder, and we announced our intent to cancel all outstanding stock options held by Mr. Schroeder that were retroactively priced or otherwise improperly granted. Those options were canceled in December 2006. Mr. Schroeder was the Company’s Chief Executive Officer and a member of its Board of Directors from mid-1999 until January 1, 2006, and was a member of the Company’s stock option committee from 1994 until December 31, 2005. From January 1, 2006 to October 16, 2006, Mr. Schroeder was employed as a Senior Advisor to the Company. On November 10, 2006, Mr. Schroeder’s counsel informed us that Mr. Schroeder contests our right to terminate his employment relationship and agreement and to cancel any of his options. We intend to vigorously defend any claims that may be made by Mr. Schroeder regarding these matters, which could involve a material amount.

Also on October 16, 2006, Stuart J. Nichols, Vice President and General Counsel, resigned. Mr. Nichols and we entered into a Separation Agreement and General Release under which Mr. Nichols’ outstanding retroactively priced stock options have been re-priced by increasing the exercise price to the market price of the option shares on the actual grant date. Under SFAS No. 123(R), no incremental charge will be recognized in the financial statements for the quarter ended December 31, 2006.

On October 16, 2006, Kenneth Levy, Founder and Chairman of the Board of Directors of the Company, retired as a director and employee, and was named Chairman Emeritus by our Board of Directors. Mr. Levy and we entered into a Separation Agreement and General Release under which Mr. Levy’s outstanding retroactively

Table of Contents

priced stock options have been re-priced by increasing the exercise price to the market price of the option shares on the actual grant date. Under SFAS No. 123(R), no incremental charge will be recognized in the financial statements for the quarter ended December 31, 2006. Mr. Levy was the Company’s Chief Executive Officer from 1975 until mid-1999 (with the exception of mid-1997 to mid-1998), was a member of the Company’s Board of Directors from 1975 until his retirement, was Chairman of the Board of Directors from 1999 until his retirement, and was a member of the Company’s stock option committee from 1994 until use of that committee was suspended in the fall of 2006.

On December 21, 2006, Jon D. Tompkins resigned as a director of the Company, and we agreed to modify the outstanding options held by Mr. Tompkins (all of which were fully vested) to extend the post-termination exercisability period to December 31, 2007, which is the last day of the calendar year in which those options would have terminated in the absence of such extension. Mr. Tompkins, the Chief Executive Officer of Tencor Instruments before its merger into the Company in mid-1997, was the Company’s Chief Executive Officer from mid-1997 to mid-1998, was a member of the Company’s stock option committee from mid-1997 until mid-1999, and was a member of the Company’s Board of Directors from mid-1997 until his resignation.

Although the Board of Directors concluded that John H. Kispert, our President and Chief Operating Officer, was not involved in and was not aware of the improper stock option practices, based on the Special Committee’s recommendation, his outstanding retroactively priced options have been re-priced because he served as Chief Financial Officer during part of the period in question. This re-pricing involved increasing the exercise price to the market price of the option shares on the actual grant date. Under SFAS No. 123(R), no incremental charge will be recognized in the financial statements for the quarter ended December 31, 2006.

Restatement and Impact on Financial Statements

In addition to restating the consolidated financial statements in response to the Special Committee’s findings, we are recording additional non-cash adjustments that were previously considered to be immaterial relating primarily to the accounting for the employee stock purchase plan, corrections for the recognition of deferred tax assets, the release of tax reserves, the timing of revenue recognition, gains and losses on hedging contracts and the calculation of minority interest. We have also corrected the classification of certain amounts presented as cash and cash equivalents and marketable securities relating to investments in Variable Rate Demand Notes. For the fiscal years ended June 30, 2004 and prior, we previously recorded no stock-based compensation expense; therefore, the additional stock-based compensation expense noted below represents the total stock-based compensation expense for these periods. For the year ended June 30, 2005, we recorded $2.9 million of stock-based compensation with a related tax benefit of $1.1 million in our previously reported financial statements. For fiscal 2005, total stock-based compensation was $37.0 million with a related tax benefit of $12.1 million. The income statement impact of the restatement is as follows (in thousands):

We adopted SFAS No. 123(R) effective July 1, 2005. The grant date fair values of stock options granted prior to fiscal year 2006 were changed as a result of the findings that certain stock option grants were retroactively priced. This change resulted in additional stock-based compensation expense of $22 million and a related tax benefit of $12 million being recognized in fiscal year 2006 under SFAS No. 123(R).

Government Inquiries Relating to Historical Stock Option Practices

We are cooperating fully with the USAO and SEC inquiries and intend to continue to do so. These inquiries likely will require us to expend significant management time and incur significant legal and other expenses, and could result in civil and criminal actions seeking, among other things, injunctions against the Company and the payment of significant fines and penalties by the Company, which may adversely affect our results of operations and cash flow. We cannot predict how long it will take or how much more time and resources we will have to expend to resolve these government inquiries, nor can we predict the outcome of these inquiries.

Late SEC Filings and Nasdaq Delisting Proceedings

Due to the Special Committee investigation and the resulting restatements, we did not file on time this Annual Report on Form 10-K and our Quarterly Report on Form 10-Q for the quarter ended September 30, 2006. As a result, we received two Nasdaq Staff Determination letters, dated September 14, 2006 and November 14, 2006, respectively, stating that we were not in compliance with the filing requirements of Marketplace Rule 4310(c)(14) and, therefore, that our stock was subject to delisting from the Nasdaq Global Select Market. We appealed this determination, attended a hearing, and obtained approval of our request for continued listing of our stock on the Nasdaq Global Select Market, subject to the condition that we file this Report and our Quarterly Report on Form 10-Q for the quarter ended September 30, 2006 on or before January 31, 2007.

With the filing of this Report and our Quarterly Report on Form 10-Q for the quarter ended September 30, 2006, we believe we have returned to full compliance with SEC reporting requirements and Nasdaq listing requirements, and, therefore, that the Nasdaq delisting matter is now closed. However, SEC comments on these Reports (or other reports that we previously filed) or other factors could render us unable to maintain an effective listing of our common stock on the Nasdaq Global Select Market or any other national securities exchange.

Shareholder Litigation Relating to Historical Stock Option Practices

Several derivative actions have been filed purporting to assert claims on behalf of and in the name of the Company against various of our current and former directors and officers relating to our accounting for stock options issued from 1994 to the present. The complaints in these actions allege that the individual defendants breached their fiduciary duties and other obligations to the Company and violated state and federal securities laws in connection with our historical stock option granting process, our accounting for past stock options, and historical sales of stock by the individual defendants. On behalf of KLA-Tencor, the plaintiffs seek unspecified monetary and other relief against the named defendants. The derivative actions are at an early stage. Our Board of Directors has appointed a Special Litigation Committee (“SLC”) composed solely of independent directors to

 

36


Table of Contents

conduct an independent investigation of the claims asserted in the derivative actions and to determine the Company’s position with respect to those claims. The SLC’s investigation is in progress. We cannot predict whether these actions are likely to result in any material recovery by or expense to KLA-Tencor.

KLA-Tencor and various of our current and former directors and officers were named as defendants in several putative securities class action lawsuits that have been consolidated into one action. The complaints allege claims under the Securities Exchange Act of 1934 as a result of our past stock option grants and related accounting and reporting, and seek unspecified monetary damages and other relief. The plaintiffs seek to represent a class consisting of purchasers of KLA-Tencor stock between February 13, 2001 and May 22, 2006 who allegedly suffered losses as a result of material misrepresentations in KLA-Tencor’s SEC filings during that period. This litigation is at an early stage. One of the derivative actions noted above also includes a putative class

action claim on behalf of KLA-Tencor shareholders against the Company and certain of our current and former directors and officers alleging that shareholders incurred damage due to purported dilution of KLA-Tencor common stock resulting from historical stock option granting practices. The Company intends to vigorously defend these litigations.

We cannot predict the outcome of the shareholder class action cases described above and we cannot estimate the likelihood or potential dollar amount of any adverse results. However, an unfavorable outcome in this litigation could have a material adverse impact upon the financial position, results of operations or cash flows for the period in which the outcome occurs and in future periods.

CRITICAL ACCOUNTING ESTIMATES AND POLICIES

The preparation of our Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions in applying our accounting policies that affect the reported amounts of assets, liabilities, revenues 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 related disclosure in this Annual Report on Form 10-K. The items in our financial statements requiring significant estimates and judgments are as follows:

Allowance for Doubtful Accounts. A majority of our trade receivables are derived from sales to large multinational semiconductor manufacturers throughout the world. In order to monitor potential credit losses, we perform ongoing credit evaluations of our customers’ financial condition. An allowance for doubtful accounts is maintained for potential credit losses based upon our assessment of the expected collectibility of all accounts receivable. The allowance for doubtful accounts is reviewed on a quarterly basis to assess the adequacy of the allowance. We take into consideration (1) any circumstances of which we are aware of a customer’s inability to meet its financial obligations; and (2) our judgments as to prevailing economic conditions in the industry and their impact on our customers. If circumstances change, and the financial condition of our customers are adversely affected and unable to meet their financial obligations to us, we may need to take additional allowances, which would result in a reduction of our net income.

Inventories. Inventories are stated at the lower of cost (on a first-in, first-out basis) or market. Demonstration units are stated at their manufacturing cost and reserves are recorded to state the demonstration units at their net realizable value. We review the adequacy of its inventory reserves on a quarterly basis. We review and set standard costs semi-annually at current manufacturing costs in order to approximate actual costs. Our manufacturing overhead standards for product costs are calculated assuming full absorption of forecasted spending over projected volumes, adjusted for excess capacity. Abnormal inventory costs such as costs of idle facilities, excess freight and handling costs, and wasted materials (spoilage) are recognized as current period charges. We write down inventory based on forecasted demand and technological obsolescence. These factors

 

37


Table of Contents

are impacted by market and economic conditions, technology changes, new product introductions and changes in strategic direction and require estimates that may include uncertain elements. Actual demand may differ from forecasted demand and such differences may have a material effect on recorded inventory values.

Warranty. We provide standard warranty coverage on our systems for 40 hours per week for twelve months, providing labor and parts necessary to repair the systems during the warranty period. We account for the estimated warranty cost as a charge to costs of revenues when revenue is recognized. The estimated warranty cost is based on historical product performance and field expenses. Utilizing actual service records, we calculate the average service hours and parts expense per system and apply the labor and overhead rates to determine the estimated warranty charge. We update these estimated charges on a quarterly basis. The actual product performance and/or field expense profiles may differ, and in those cases we adjust our warranty reserves accordingly. The difference between the estimated and actual warranty costs tends to be larger for new product introductions as there is limited or no historical product performance to estimate warranty expense; more mature products with longer product performance histories tend to be more stable in our warranty charge estimates. Non-standard warranty generally 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. See Note 12 to Consolidated Financial Statements “Commitments and Contingencies” for a detailed description.

Revenue Recognition. We recognize revenue when persuasive evidence of an arrangement exists, the sale price is fixed or determinable, delivery has occurred or services have been rendered, and collectibility is reasonably assured. System revenue includes hardware and software that is incidental to the product. We generally recognize system revenue upon confirmation by the customer that the system has been installed and is operating according to pre-determined specifications. In certain cases, our policy does not require written acceptance from the customer and we recognize system revenue upon shipment. Total revenue recognized without a written acceptance from the customer was approximately 4.4%, 6.6%, and 4.9% of total revenue for the fiscal years ended June 30, 2006, 2005 and 2004, respectively. The fluctuation of revenue exceptions is primarily driven by the shipment patterns of tools that have already met the required acceptance criteria. (See Note 1 to Consolidated Financial Statements under “Revenue Recognition” for detailed description of exceptions.) Shipping charges billed to customers are included in system revenue and the related shipping costs are included in costs of revenues.

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 unspecified software 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. We periodically review the software element of our systems in accordance with AICPA Statement of Position (“SOP”) No. 97-2, “Software Revenue Recognition” and Emerging Issues Task Force (“EITF”) Issue No. 03-05, “Applicability of SOP 97-2 to Non-Software Deliverables in an Arrangement Containing More-Than-Incidental Software.”

Trade-in rights are occasionally granted to customers to trade in tools in connection with subsequent purchases. We estimate the value of the trade-in right and reduce the revenue of the initial sale.

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

 

38


Table of Contents

maintenance are allocated based on vendor specific objective evidence. Consulting and training revenue is recognized when the related services are performed.

The deferred system profit balance at June 30, 2006 was $226 million. This amount equals the amount of deferred system revenue that was invoiced and due on shipment less applicable product and warranty costs. The deferred profit balance increased from $212 million at June 30, 2005 primarily because shipments were higher than customer acceptance for which revenue was recognized during fiscal year 2006.

We also defer the fair value of non-standard warranty bundled with equipment sales as unearned revenue. Non-standard warranty includes services incremental to the standard 40-hour per week coverage for twelve months. Non-standard warranty is recognized ratably as revenue when the applicable warranty term period commences. The unearned revenue balance was flat at $81 million at June 30, 2006 and 2005.

Stock-Based Compensation. Prior to July 1, 2005, we applied APB Opinion No. 25, “Accounting for Stock Issued to Employees,” and its related Interpretations and provided the required pro forma disclosures under SFAS No. 123, “Accounting for Stock-Based Compensation.” In accordance with APB Opinion No. 25, a non-cash, stock-based compensation expense was recognized for any options for which the exercise price was below the market price on the actual grant date. The charge for the options with an exercise price below the market price on the actual grant date was equal to the number of options multiplied by the difference between the exercise price and the market price of the option shares on the actual grant date. That expense was amortized over the vesting period of the option. Beginning July 1, 2005, we have accounted for stock-based compensation using the fair value of stock options using a Black-Scholes valuation model, consistent with the provisions of SFAS No. 123(R), Securities and Exchange Commission Staff Accounting Bulletin (“SAB”) No. 107. We elected to adopt the modified prospective application method as provided by SFAS No. 123(R). Accordingly, during fiscal year 2006, we recorded stock-based compensation cost totaling the amount that would have been recognized had the fair value method under SFAS No. 123 been applied since the effective date of SFAS No. 123 for the pre-fiscal 2006 grants and under SFAS No. 123(R) for the fiscal year 2006 grants. SFAS No. 123(R) 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. The expected stock price volatility assumption was determined using the implied volatility of the Company’s common stock. We determined that implied volatility is more reflective of market conditions and a better indicator of expected volatility than a blended volatility. Prior to the adoption of SFAS No. 123(R), we used a combination of historical and implied volatility in deriving the expected volatility assumption. In November 2005, the Financial Accounting Standards Board (“FASB”) issued FASB Staff Position (“FSP”) No. 123(R)-3, “Transition Election Related to Accounting for Tax Effects of Share-Based Payment Awards” (“FSP 123R-3”). We have elected not to adopt the alternative transition method provided in the FSP 123R-3 for calculating the tax effects of stock-based compensation pursuant to SFAS No. 123(R). We followed paragraph 81 of SFAS No. 123(R) to calculate the initial pool of excess tax benefits and to determine the subsequent impact on the Additional Paid-In-Capital (“APIC”) pool and Consolidated Statements of Cash Flows of the tax effects of employee stock-based compensation awards that are outstanding upon adoption of SFAS No. 123(R). See Note 7 to Consolidated Financial Statements “Stock-Based Compensation” for a detailed description.

Contingencies and Litigation. The Company is subject to the possibility of losses from various contingencies. Considerable judgment is necessary to estimate the probability and amount of any loss from such contingencies. An accrual is made when it is probable that a liability has been incurred or an asset has been impaired and the amount of loss can be reasonably estimated. The Company accrues a liability and charges operations for the estimated costs expected to be incurred over the next twelve months of adjudication or settlement of asserted and unasserted claims existing as of the balance sheet date. See Note 12 to Consolidated Financial Statements “Commitments and Contingencies” for a detailed description.

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.

On a quarterly basis, we provide for income taxes based upon an estimated annual 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.

In addition, the calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax regulations. We recognize liabilities for anticipated tax audit issues in the U.S. and other tax jurisdictions based on our estimate of whether, and the extent to which, additional tax payments are probable. If we ultimately determine that payment of these amounts is unnecessary, we reverse the liability and recognize a tax benefit during the period in which we determine that the liability is no longer necessary. We record an additional charge in our provision for taxes in the period in which we determine that the recorded tax liability is less than we expect the ultimate assessment to be. See Note 11 to Consolidated Financial Statements “Income Taxes” for a detailed description.

Effects of Recent Accounting Pronouncements.

In September 2006, the SEC staff issued Staff Accounting Bulletin (“SAB”) No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements.” SAB No. 108 was issued in order to eliminate the diversity of practice surrounding how public companies quantify financial statement misstatements. SAB No. 108 requires registrants to quantify the impact of correcting all misstatements using both the “rollover” method, which focuses primarily on the impact of a misstatement on the income statement and is the method we currently use, and the “iron curtain” method, which focuses primarily on the effect of correcting the period-end balance sheet. The use of both of these methods is referred to as the “dual approach” and should be combined with the evaluation of qualitative elements surrounding the errors in accordance with SAB No. 99, “Materiality.” The provisions of SAB No. 108 are effective for the Company for fiscal years beginning July 1, 2006. The adoption of SAB No. 108 is not expected to have a material impact on the Company’s consolidated financial position, results of operations or cash flows.

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements.” SFAS No. 157 defines fair value, establishes a framework for measuring fair value in accordance with generally accepted accounting principles, and expands disclosures about fair value measurements. The provisions of SFAS No. 157 are effective for the Company for fiscal years beginning July 1, 2008. We are evaluating the impact of the provisions of this statement on the Company’s consolidated financial position, results of operations and cash flows.

In September 2006, the FASB issued SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans.” SFAS No. 158 requires employers to fully recognize the obligations associated with single-employer defined benefit pension, retiree healthcare and other postretirement plans in their financial statements. The provisions of SFAS No. 158 are effective for the Company as of the end of the fiscal year ending June 30, 2007. We are evaluating the impact of the provisions of this statement on the Company’s consolidated financial position, results of operations and cash flows.

In June 2006, the FASB published FASB Interpretation No. (“FIN”) 48, “Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109,” which clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements in accordance with SFAS No. 109, “Accounting for Income Taxes.” This Interpretation prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. This Interpretation also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. This Interpretation is effective for the Company in fiscal years beginning July 1, 2007. We are evaluating the impact of the provisions of this Interpretation on the Company’s consolidated financial position, results of operations and cash flows.

In February 2006, the FASB issued SFAS No. 155, “Accounting for Certain Hybrid Financial Instruments,” an amendment of SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities,” and SFAS No. 140, “Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities.” This Statement permits fair value remeasurement for any hybrid financial instrument that contains an embedded derivative that otherwise would require bifurcation. This Statement is effective for the Company for all financial instruments acquired or issued after July 1, 2007. The adoption of SFAS No. 155 is not expected to have a material effect on the Company’s consolidated financial position, results of operations or cash flows.

In June 2005, the FASB issued SFAS No. 154, “Accounting Changes and Error Corrections,” a replacement of APB Opinion No. 20, “Accounting Changes,” and SFAS No. 3, “Reporting Accounting Changes in Interim Financial Statements.” SFAS No. 154 changes the requirements for the accounting for and reporting of a change in accounting principle. Previously, most voluntary changes in accounting principles required recognition via a cumulative effect adjustment within net income of the period of the change. SFAS No. 154 requires retrospective application to prior periods’ financial statements, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. SFAS No. 154 is effective for the Company for accounting changes made in fiscal years beginning July 1, 2006; however, the Statement does not change the transition provisions of any existing accounting pronouncements. The adoption of SFAS No. 154 is not expected to have a material effect on the Company’s consolidated financial position, results of operations or cash flows.

In March 2005, the FASB published FIN 47, “Accounting for Conditional Asset Retirement Obligations,” which clarifies that the term, conditional asset retirement obligation, as used in SFAS No. 143, “Accounting for Asset Retirement Obligations,” refers to a legal obligation to perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event that may or may not be within the control of the entity. The uncertainty about the timing and (or) method of settlement of a conditional asset retirement obligation should be factored into the measurement of the liability when sufficient information exists. The Interpretation also clarifies when an entity would have sufficient information to reasonably estimate the fair value of an asset retirement obligation. The adoption of this Interpretation did not have a material effect on our consolidated financial position, results of operations or cash flows.

In December 2004, the FASB issued SFAS No. 153, “Exchanges of Nonmonetary Assets,” an amendment of APB Opinion No. 29. SFAS No. 153 addresses the measurement of exchanges of nonmonetary assets and redefines the scope of transactions that should be measured based on the fair value of the assets exchanged. SFAS No. 153 is effective for the Company for nonmonetary asset exchanges beginning in the first quarter of fiscal 2006. The adoption of SFAS No. 153 did not have a material effect on our consolidated financial position, results of operations or cash flows.

In November 2004, the FASB issued SFAS No. 151, “Inventory Costs,” an amendment of Accounting Research Bulletin (“ARB”) No. 43, Chapter 4. SFAS No. 151 clarifies that abnormal inventory costs such as costs of idle facilities, excess freight and handling costs, and wasted materials (spoilage) are required to be recognized as current period charges. The provisions of SFAS No.151 are effective for the Company for fiscal years beginning July 1, 2005. The adoption of SFAS No. 151 did not have a material impact on our consolidated financial position, results of operations or cash flows.

Industry Trends

Industry analysts have predicted that semiconductor revenues and semiconductor equipment revenues will each grow in the ranges of -5% to +10% in calendar year 2007. Over the longer term, we expect process control to continue to represent a higher percentage of our customers’ capital spending. We believe this percentage 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 new materials, new devices and circuit architecture, new lithography challenges and fab process innovation. We anticipate these factors will drive increased demand for our products and services. The key drivers for growth in the semiconductor equipment industry in calendar year 2007 are the transition to 300 millimeter fabs, the increased demand for consumer electronics and the strength of the NAND flash market.

Product revenues

For the year ended June 30, 2006

Product revenue in fiscal year 2006 decreased $55 million, or 3%, to $1.7 billion, from $1.8 billion in fiscal year 2005. Product revenue in fiscal year 2005 increased $568 million, or 47% to $1.8 billion, from $1.2 billion in fiscal year 2004. Product revenue increased in fiscal year 2005 primarily as a result of fulfilling a higher level of orders received in prior periods. Our customers’ increased capital spending in the area of process control and yield management is due to the increasing complexity of processing in their fabs as more complex chips are produced, new materials such as copper are introduced and device feature sizes are reduced.

Per our revenue recognition policy, we do not require written acceptance from the customer under certain situations. Revenue recognized under conditions where our policy does not require the need for a written acceptance by the customer was approximately 4.4%, 6.6% and 4.9% of total revenue for fiscal years 2006, 2005 and 2004, respectively.

Service revenues

Service revenue in fiscal year 2006 increased $44 million, or 14% to $358 million, from $314 million in fiscal year 2005. Service revenue in fiscal year 2005 increased $17 million, or 6% to $314 million, from $297 million in fiscal year 2004. 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 continued to increase through the three year period as our installed base of equipment at our customers’ sites continued to grow. The amount of service revenue generated is generally a function of the number of post-warranty systems installed at our customers’ sites and the utilization of those systems.

International revenues were 80%, 76% and 77% of revenue during the fiscal years ended June 30, 2006, 2005 and 2004, respectively. A significant portion of our revenue continues to be generated in Asia where a substantial portion of the world’s semiconductor manufacturing capacity is located.

Gross margin

Our gross margin fluctuates with revenue levels and product mix, and is affected by variations in costs related to manufacturing and servicing our products. Gross margin decreased by 3 points to 55% during fiscal year 2006 from 58% during fiscal year 2005 primarily due to cessation of development work related to CDSEM and stock-based compensation expense recorded during fiscal year 2006, which contributed 1% and 1%, respectively, to the decrease in gross margin. During the fourth quarter of fiscal year 2006, we ceased development work on the next generation equipment for CDSEM and incurred charges of $27 million related to write-offs of inventory as well as for liabilities incurred related to the decision to cease future development of CDSEM. Although we have ceased future development of CDSEM, we will continue to service previously sold equipment. Gross margin improved by 4 points to 58% in fiscal year 2005 relative to 54% in fiscal year 2004 due to lower cost of building, installing and maintaining our products, combined with an increase in revenues.

R&D expenses increased $42 million or 12% to $394 million during fiscal year 2006 from $352 million during fiscal year 2005. R&D expenses increased $53 million or 18% to $352 million during fiscal year 2005 from $299 million during fiscal year 2004. The increase in R&D expenses in 2006 is primarily attributable to increased stock-based compensation expenses. In addition, the increase in R&D expenses compared to fiscal year 2004 is due to the business acquired during 2005. Note, however, that R&D expenses, as a percentage of total revenues, decreased from fiscal year 2004 to fiscal year 2005 as a result of higher total revenues during fiscal year 2005.

Table of Contents

R&D expenses include the benefit of $11 million, $8 million and $11 million of external funding received during the fiscal years 2006, 2005 and 2004, respectively, for certain strategic development programs conducted with several of our customers and from government grants. We expect our R&D expenses to increase in absolute dollars as we accelerate our investments in critical programs focusing on new technologies and enhancements to existing products.

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. We remain committed to product development in new and emerging technologies as we address the yield challenges our customers face at future technology nodes.

Selling, General and Administrative (“SG&A”)

     4 %     1 %     2 %

SG&A expenses increased $111 million or 35% to $425 million during fiscal year 2006 from $314 million during the fiscal year 2005. SG&A expenses increased $43 million or 16% to $314 million during fiscal year 2005 from $271 million during fiscal year 2004.

The increase in SG&A expenses from fiscal year 2005 to fiscal year 2006 is primarily due to higher levels of stock-based compensation expense; increased compensation expense of $70 million and increased legal costs of $21 attributable to accrued expenses related to the stock option investigation. The increase in SG&A expenses from fiscal year 2004 to fiscal year 2005 is primarily due to higher compensation costs associated with an increase in customer application support, increased staffing and consolidating the results of operations of the entities acquired during fiscal year 2005.

During November 2005, we announced that effective January 1, 2006, Kenneth L. Schroeder would cease to be our Chief Executive Officer and would thereafter be employed as a Senior Advisor. The Company and Mr. Schroeder also revised his prior agreement with the Company and defined the salary, bonus payout and equity award vesting during the period of his employment as a Senior Advisor. Effective January 1, 2006, we determined that all service conditions associated with certain prior equity awards under the terms of the revised agreement with Mr. Schroeder had been satisfied; accordingly, we recorded at that time an additional non-cash, stock-based compensation charge of approximately $9.8 million relating to these equity awards. The above-mentioned charge is included as a component of Selling, General and Administrative expense during fiscal 2006. On October 16, 2006, following the Special Committee investigation of our historical stock option practices, we terminated all aspects of Mr. Schroeder’s employment relationship and agreement with the Company. As a result, vesting of Mr. Schroeder’s then outstanding stock options and restricted stock awards immediately ceased, and the 890,914 unvested option shares and 100,000 unvested restricted stock award shares held by Mr. Schroeder at the time of termination were canceled. Accordingly, in the second quarter of fiscal 2007 we will reverse approximately $20 million of the non-cash, stock-based compensation charge recorded in prior periods. In December 2006, we canceled 596,740 vested option shares held by Mr. Schroeder as of the time of termination, representing those shares that had been retroactively priced or otherwise improperly granted.

In November 2006, as part of the long-term business plan, we decided to sell certain real estate properties owned by the Company in San Jose, California and Livermore, California. We will record an asset impairment charge of approximately $56 million in the quarter ended December 31, 2006. In addition, we reduced our work-force by approximately 150 people and will accrue approximately $10 million in severance charges in the quarter ended December 31, 2006 to be paid over the next twelve months.

Interest Income and Other, Net

Interest income and other, net

Percentage of total revenues

     3 %     2 %     2 %

Interest income and other, net is comprised primarily of interest income earned on the investment and cash portfolio, realized gains or losses on sales of marketable securities, as well as income recognized upon settlement of certain foreign currency contracts. The increase in interest income and other, net, compared to the prior fiscal years is primarily due to the increase in cash levels and short-term interest rates.

Provision for Income Taxes

Our effective income tax rate was 0.4%, 24.3% and 21.4% in fiscal years 2006, 2005 and 2004, respectively. In general, our effective income tax rate differs from the statutory rate of 35% largely as a function of benefits realized from our Extraterritorial Income (“ETI”) exclusion, research and development tax credits and tax exempt interest.

In the year ended June 30, 2006, the Company reduced its total income tax reserves by $79.7 million, of which $44.8 million relates to the fourth quarter of fiscal year 2006. This was primarily due to expiring statute of limitations, several tax settlements reached with various tax authorities and reassessments of tax exposures based on the status of current audits in various jurisdictions. Included in the tax settlements, was a settlement with the Internal Revenue Service related to an examination for the years ended June 30, 2003 and 2004.

Our benefits for income taxes related to equity awards were $58.2 million, $12.1 million and $22.3 million for the fiscal years ended June 30, 2006, June 30, 2005 and June 30, 2004, respectively.

Our future effective income tax rate depends on various factors, such as tax legislation, the geographic composition of our pre-tax income, non tax-deductible expenses incurred in connection with acquisitions, amounts of tax-exempt interest income and research and development credits as a percentage of aggregate pre-tax income, and the effectiveness of our tax planning strategies.

The Internal Revenue Service completed an audit of the Company’s fiscal year 2003 and 2004 corporate tax returns. Liabilities for anticipated worldwide tax audit issues have been established based on our estimate of whether, and the extent to which, additional tax payments are probable. The Company believes that adequate reserves have been provided to cover any potential additional tax assessments.

Equity Incentive Program

The Company’s equity incentive program is a broad-based, long-term retention program that is intended to attract and retain key employees, and align stockholder and employee interests. The equity incentive program consists of two plans: one under which non-employee directors may be granted options to purchase shares of our stock, and another in which non-employee directors, officers, key employees, consultants and all other employees may be granted options to purchase shares of our stock, restricted stock units and other types of equity awards. For the past several years, except for the retroactively priced stock options, stock options have generally been granted at market price of our common stock on the date of grant, generally have a vesting period of five

Table of Contents

years and are exercisable for a period not to exceed seven years (ten years for options granted prior to July 1, 2005) from the date of issuance. Restricted stock units may be granted with varying criteria such as time-based or performance-based vesting. Substantially all of our employees that meet established performance goals and qualify as key employees participate in our main equity incentive plan.

On October 18, 2004, the Company’s stockholders approved the 2004 Equity Incentive Plan (the “2004 Plan”) which provides for the grant of options to purchase shares of the Company’s common stock, stock appreciation rights, restricted stock, performance shares, performance units and deferred stock units to our employees, consultants and members of our Board of Directors. Since the adoption of the 2004 Plan, no further grants are permitted under the 1982 Stock Option Plan or 2000 Non-Statutory Stock Option Plan. The 2004 Plan permits the issuance of 12,500,000 shares of common stock, of which 6.3 million shares are available for grant as of June 30, 2006. At that date, awards for 30.4 million shares are outstanding under all plans.

Stock-Based Compensation Expense

Effective July 1, 2005, we adopted the provisions of SFAS No. 123(R), “Share-Based Payment.” SFAS No. 123(R) establishes accounting for stock-based awards exchanged for employee services. Accordingly, stock-based compensation cost is measured at grant date, based on the fair value of the award which is computed using a Black-Scholes option valuation model, and is recognized as expense over the employee’s requisite service period.

During fiscal years 2006, 2005, and 2004, we recorded stock-based compensation expense of $165 million, $37 million, and $53 million, respectively, of which, $22 million, $34 million, and $53 million was attributable to the restatements.

Compensation expense recognized for all stock options for fiscal years 2006, 2005, and 2004 was $141 million, $35 million, and $53 million, respectively. As of June 30, 2006, the unrecognized stock-based compensation after estimated forfeitures related to stock options was $223 million and is expected to be recognized over an estimated weighted-average amortization period of 3.3 years.

Compensation expense recognized in connection with the employee stock purchase plan for fiscal year 2006 was $16 million, the majority of which is included in selling, general and administration expense. As the plan was non-compensatory under APB Opinion No. 25, no compensation expense was recorded in connection with the plan in fiscal years 2005 and 2004.

Compensation expense recognized for restricted stock units for fiscal years 2006 and 2005 was $8 million and $2 million, respectively. No compensation expense was recognized in fiscal year 2004. As of June 30, 2006, the unrecognized stock-based compensation after estimated forfeitures related to restricted stock units was $26 million. That cost is expected to be recognized over an estimated weighted-average amortization period of 3.7 years.

We have historically financed our operations through cash generated from operations. Cash provided by operating activities was $315 million, $507 million, and $350 million in fiscal years 2006, 2005 and 2004, respectively. Cash provided by operating activities in fiscal year 2006 consisted primarily of net income of $380 million increased by non-cash depreciation and amortization of $69 million, stock-based compensation of $165 million, tax benefit from equity awards of $32 million and an increase in accounts payable of $27 million, partially offset by an increase in accounts receivable of $115 million, an increase in inventories of $88 million, and an increase in net deferred income tax assets of $134 million.

Cash provided by operating activities in fiscal year 2005 consisted primarily of net income of $445 million increased by non-cash depreciation and amortization of $70 million, stock-based compensation of $37 million, decrease in accounts receivable of $37 million and decrease in other assets and liabilities of $43 million partially offset by a decrease in deferred system profit of $71 million and an increase in net deferred income tax assets of $53 million.

Cash provided by operating activities during fiscal year 2004 consisted primarily of net income of $212 million, increased by non-cash depreciation and amortization of $82 million, stock-based compensation of $53 million, tax benefit from equity awards of $40 million, an increase in deferred system profit of $107 million and an increase in accounts payable of $30 million partially offset by an increase in other assets and liabilities of $87 million, an increase in net deferred income tax assets of $29 million, an increase in accounts receivable of $149 million and an increase in inventories of $76 million.

Cash provided by investing activities was $225 million in fiscal year 2006. Cash used in investing activities was $125 million and $441 million in fiscal years 2005 and 2004, respectively. Investing activities typically consist of purchases and sales or maturities of marketable securities, purchases of capital assets to support long-term growth and acquisitions of technology or other companies to allow access to new markets or emerging technologies.

Cash used in financing activities was $85 million and $81 million in fiscal years 2006 and 2005, compared with $113 million of cash generated from financing activities in fiscal year 2004. Financing activities include dividend payments to our common stockholders and sales and repurchases of our common stock. Issuance of common stock provided $213 million, $134 million and $169 million in fiscal years 2006, 2005 and 2004, respectively. We used $221 million, $204 million and $56 million in fiscal years 2006, 2005 and 2004, respectively, to repurchase shares of our common stock under the stock repurchase program initiated in 1997. The stock repurchase program was suspended in May 2006. We anticipate resuming repurchases under the program in calendar 2007. During the third quarter of fiscal 2005, our Board of Directors also approved the initiation of a quarterly cash dividend and declared a dividend of 12 cents per share of our outstanding common stock. The total amount of dividends paid during the fiscal years 2006 and 2005 was $95 million and $24 million, respectively. Further, the dividend of 12 cents per share for the first quarter of fiscal 2007 was declared on August 3, 2006 and was paid on September 1, 2006 to our stockholders on record as of August 15, 2006. The total amount of dividends paid during the first quarter of fiscal 2007 was approximately $24 million. In addition, the dividend of 12 cents per share for the second quarter of fiscal 2007 was declared on November 6, 2006 and was paid on December 1, 2006 to our stockholders on record as of November 15, 2006. The total amount of dividends paid in the second quarter of fiscal 2007 was $24 million.

On October 11, 2006, we acquired all of the shares of ADE Corporation (“ADE”), a supplier of semiconductor process control solutions. Per the Amended Merger Agreement between the Company and ADE, we paid $482 million (which included goodwill and intangibles of $262 million and $137 million, respectively) in cash to the shareholders of ADE. The acquisition will be accounted for as a purchase.

        2007    2008    2009    2010    2011    Thereafter

Operating leases

   $ 19.7    $ 6.5    $ 4.6    $ 3.4    $ 1.9    $ 1.3    $ 2.0

Cash purchase of ADE

   $ 482.0    $ 482.0               
                                                

Total contractual cash obligations

   $ 501.7    $ 488.5    $ 4.6    $ 3.4    $ 1.9    $ 1.3    $ 2.0

We have agreements with financial institutions to sell certain of our trade receivables and promissory notes from customers without recourse. During the years ended June 30, 2006 and 2005, approximately $278 million and $306 million of receivables were sold under these arrangements, respectively.

In addition, from time to time we will discount without recourse, Letters of Credit (“LCs”) received from customers in payment of goods. During the years ended June 30, 2006 and 2005, several LCs were sold with proceeds totaling $69 million and $30 million, respectively. Discounting fees were $0.8 million and $0.2 million for the years ended June 30, 2006 and 2005, respectively.

We maintain $25 million of short-term credit facilities in various locations to fund overdraft, Custom’s guarantee for VAT, and letter of credit needs of our subsidiaries in Europe and Asia. A total of $20 million was outstanding under these facilities as of June 30, 2006.

We maintain certain 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 among different suppliers. We estimate our purchase commitment as of June 30, 2006 to be approximately $210 million, most of which we expect to spend in fiscal year 2007. 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 change in the event that the arrangements are renegotiated or canceled. Certain agreements provide for potential cancellation penalties.

We provide standard warranty coverage on our systems for 40 hours per week for twelve months, providing labor and parts necessary to repair the systems during the warranty period. We account for the estimated warranty cost as a charge to costs of revenues when revenue is recognized. The estimated warranty cost is based on historical product performance and field expenses. The actual product performance and/or field expense profiles may differ, and in those cases we adjust our warranty reserves accordingly. The difference between the estimated and actual warranty costs tends to be larger for new product introductions as there is limited or no historical product performance to estimate warranty expense; more mature products with longer product performance histories tend to be more stable in our warranty charge estimates. Non-standard warranty coverage generally includes services incremental to the standard 40-hour per week coverage for twelve months. See Note 12 to Consolidated Financial Statements “Commitments and Contingencies” for a detailed description.

We are involved in several litigation cases as described in Note 12 to Consolidated Financial Statements. We cannot predict the outcome of these cases and we cannot estimate the likelihood or potential dollar amount of any adverse results.

Working capital increased to $2.5 billion as of June 30, 2006, compared to $2.3 billion at June 30, 2005. At June 30, 2006, our principal sources of liquidity consisted of $2.3 billion of cash, cash equivalents, and marketable securities. Our liquidity is affected by many factors, some of which are based on the normal ongoing operations of the business, and others of which relate to the uncertainties of global economies and the semiconductor and the semiconductor equipment industries. Although cash requirements will fluctuate based on the timing and extent of these factors, we believe that cash generated from operations, together with the liquidity

provided by existing cash balances, will be sufficient to satisfy our liquidity requirements for at least the next twelve months.

Off-Balance Sheet Arrangements

Under our foreign-currency risk management strategy, we utilize derivative instruments to protect our interests from unanticipated fluctuations in earnings and cash flows caused by volatility in currency exchange rates. This financial exposure is monitored and managed as an integral part of our overall risk management program which focuses on the unpredictability of financial markets and seeks to reduce the potentially adverse effects that the volatility of these markets may have on our operating results. We continue our policy of hedging our current and anticipated foreign currency exposures with hedging instruments having tenors of up to twelve months. At June 30, 2006, we had cash flow hedge contracts, maturing throughout fiscal year 2007 to sell $167.5 million and purchase $15.2 million, in foreign currency, primarily in Japanese Yen. At June 30, 2006, we had other foreign currency hedge contracts maturing throughout fiscal year 2007 to sell $260.2 million and purchase $128.4 million, in foreign currency, primarily in Japanese Yen.

 

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE 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, such as foreign currency hedges. 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 June 30, 2006. Actual results may differ materially.

As of June 30, 2006, we had an investment portfolio of fixed income securities of $1.2 billion, excluding those classified as cash and cash equivalents (detail of these securities is included in Note 4 of the Notes to Consolidated Financial Statements found under Item 8, “Financial Statements and Supplementary Data” in this Annual Report on Form 10-K). 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 June 30, 2006, the fair value of the portfolio would decline by $7 million.

As of June 30, 2006, we had net forward contracts to sell $284 million in foreign currency in order to hedge certain currency exposures (detail of these contracts and Hedging Activities is included in Note 13 to Consolidated Financial Statements under “Derivative Instruments”). If we had entered into these contracts on June 30, 2006, the U.S. dollar equivalent would be $288 million. A 10% adverse move in all currency exchange rates affecting the contracts would decrease the fair value of the contracts by $39 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 the hedging of certain of our foreign currency exposure should have no material impact on income or cash flows.

KLA-TENCOR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Operations and Principles of Consolidation. KLA-Tencor Corporation (“KLA-Tencor” or the “Company”) is a global provider of process control and yield management solutions for the semiconductor manufacturing and related microelectronics industries. Headquartered in San Jose, California, KLA-Tencor has subsidiaries both in the United States and in key markets throughout the world.

The Consolidated Financial Statements include the accounts of KLA-Tencor and its majority-owned subsidiaries, and the ownership interests of minority investors are recorded as minority interests. All significant intercompany balances and transactions have been eliminated.

Management Estimates. The preparation of the 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 and liabilities at the date of the Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

Fair Value of Financial Instruments. KLA-Tencor has evaluated the estimated fair value of financial instruments using available market information and valuation methodologies as provided by the custodian. 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 approximate their carrying amounts due to the relatively short maturity of these items.

Cash Equivalents and Marketable Securities. All highly liquid debt instruments with original or remaining maturities of less than three months at the date of purchase are considered to be cash equivalents. Marketable securities are generally classified as available-for-sale and are reported at fair value, with unrealized gains and losses, net of tax, presented as a separate component of accumulated other comprehensive income. The fair value of marketable securities is based on quoted market prices. All realized gains and losses and unrealized losses and declines in fair value that are other than temporary are recorded in earnings in the period of occurrence. The specific identification method is used to determine the realized gains and losses on investments.

Non-Marketable Equity Securities and Other Investments. KLA-Tencor acquires certain equity investments for the promotion of business and strategic objectives, and to the extent these investments continue to have strategic value, KLA-Tencor typically does not attempt to reduce or eliminate the inherent market risks. Non-marketable equity securities and other investments are recorded at historical cost. If KLA-Tencor has the ability to exercise significant influence over the investee, but does not have control, KLA-Tencor’s proportionate share of income or losses from investments is accounted for under the equity method and any gain or loss is recorded in interest income and other, net. Non-marketable equity securities, equity-method investments, and other investments are included in “Other assets” on the balance sheet. Non-marketable equity securities are subject to a periodic impairment review; however, there are no open-market valuations, and the impairment analysis requires significant judgment. This analysis includes assessment of the investee’s financial condition, the business outlook for its products and technology, its projected results and cash flow, the likelihood of obtaining subsequent rounds of financing and the impact of any relevant contractual equity preferences held by KLA-Tencor or others. If an investee obtains additional funding at a valuation lower than KLA-Tencor’s carrying amount, it is presumed that the investment is other than temporarily impaired, unless specific facts and circumstances indicate otherwise, for example if KLA-Tencor holds contractual rights that include a preference over the rights of other investors.

Inventories. Inventories are stated at the lower of cost (on a first-in, first-out basis) or market. Demonstration units are stated at their manufacturing cost and reserves are recorded to state the demonstration

units at their net realizable value. KLA-Tencor reviews the adequacy of its inventory reserves on a quarterly basis. The Company reviews and sets standard costs semi-annually at current manufacturing costs in order to approximate actual costs. The Company’s manufacturing overhead standards for product costs are calculated assuming full absorption of forecasted spending over projected volumes, adjusted for excess capacity. Abnormal inventory costs such as costs of idle facilities, excess freight and handling costs, and wasted materials (spoilage) are recognized as current period charges. The Company writes down inventory based on forecasted demand and technological obsolescence. These factors are impacted by market and economic conditions, technology changes, new product introductions and changes in strategic direction and require estimates that may include uncertain elements. Actual demand may differ from forecasted demand and such differences may have a material effect on recorded inventory values.

Property and Equipment. Property and equipment are recorded at cost, net of accumulated depreciation. Depreciation of property and equipment is based on the straight-line method over the estimated useful lives of the assets, which are thirty to thirty-five years for buildings, ten to fifteen years for leasehold improvements, five to seven years for furniture and fixtures, and three to five years for machinery and equipment. Leasehold improvements are amortized by the straight-line method over the shorter of the life of the related asset or the term of the underlying lease. Construction in process does not depreciate until the assets are placed in service. Depreciation expense for the years ended June 30, 2006, 2005 and 2004 was $52 million, $48 million, and $46 million, respectively.

Goodwill and Intangible Assets. As required by Statement of Financial Accounting Standards (“SFAS”) No. 142, goodwill is not amortized but is subject to impairment tests annually, or earlier if indicators of potential impairment exist, using a fair-value-based approach. Purchased technology, patents, trademarks and other intangible assets are presented at cost, net of accumulated amortization. Intangible assets are amortized over their estimated useful lives and assessed for impairment under SFAS No. 144. The Company completed its annual evaluation of the goodwill by reporting unit during the quarter ended December 31, 2005, and concluded that there was no impairment. There have been no significant events or circumstances affecting the valuation of goodwill subsequent to the impairment test performed in the second quarter of fiscal year 2006.

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 SFAS 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. Such an impairment charge would be measured as the excess of the asset over its fair value.

Software Development Costs. KLA-Tencor capitalizes certain internal and external costs incurred to acquire and create internal use software in accordance with AICPA Statement of Position (“SOP”) No. 98-1, “Accounting for the Costs of Computer Software Developed or Obtained for Internal Use.” Capitalized software is included in property and equipment when development is complete and is depreciated over three to five years when placed in service.

Concentration of Credit Risk. Financial instruments that potentially subject KLA-Tencor to significant concentrations of credit risk consist primarily of cash equivalents, short-term and non-current marketable securities, trade accounts receivable and derivative financial instruments used in hedging activities. KLA-Tencor invests in a variety of financial instruments, such as, but not limited to, certificates of deposit, corporate and municipal bonds, United States Treasury and agency securities, equity securities and, by policy, limits the amount of credit exposure with any one financial institution or commercial issuer. KLA-Tencor has not experienced any material credit losses on its investments.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

A majority of KLA-Tencor’s trade receivables are derived from sales to large multinational semiconductor manufacturers located throughout the world and in majority in Asia. 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 and generally requires no collateral to secure accounts receivable. KLA-Tencor maintains an allowance for potential credit losses based upon expected collectibility of all accounts receivable. In addition, KLA-Tencor may utilize letters of credit or non-recourse factoring to mitigate credit risk when considered appropriate.

KLA-Tencor is exposed to credit loss in the event of nonperformance by counterparties on the foreign exchange contracts used in hedging activities and in certain factoring transactions. These counterparties are large international financial institutions and to date, no such counterparty has failed to meet its financial obligations under such contracts.

Foreign Currency. The functional currencies of KLA-Tencor’s significant foreign subsidiaries are generally the local currencies. Accordingly, all assets and liabilities of the foreign operations are translated to U.S. dollars at current period end exchange rates, and revenues and expenses are translated to U.S. dollars using average exchange rates in effect during the period. The gains and losses from foreign currency translation of these subsidiaries’ financial statements are recorded directly into a separate component of stockholders’ equity under the caption “Accumulated other comprehensive income.”

KLA-Tencor’s subsidiaries in Israel and Singapore use the U.S. dollar as their functional currency. Accordingly, assets and liabilities of these subsidiaries are translated using exchange rates in effect at the end of the period, except for non-monetary assets, such as inventories and property, plant and equipment that are translated using historical exchange rates. Revenues and costs are translated using average exchange rates for the period, except for costs related to those balance sheet items that are translated using historical exchange rates. The resulting translation gains and losses are included in the Consolidated Statements of Operations as incurred.

Derivative Financial Instruments. KLA-Tencor uses financial instruments, such as forward exchange contracts, to hedge a portion of, but not all, existing and forecasted foreign currency denominated transactions expected to occur within twelve months. The purpose of KLA-Tencor’s foreign currency program is to manage the effect of exchange rate fluctuations on certain foreign currency denominated revenues, costs and eventual cash flows. The effect of exchange rate changes on forward exchange contracts is expected to offset the effect of exchange rate changes on the underlying hedged items. KLA-Tencor believes these financial instruments do not subject it to speculative risk that would otherwise result from changes in currency exchange rates. KLA-Tencor does not use derivative financial instruments for speculative or trading purposes.

All of KLA-Tencor’s derivative financial instruments are recorded at fair value based upon quoted market prices for comparable instruments. For derivative instruments designated and qualifying as cash flow hedges of forecasted foreign currency denominated transactions, the effective portion of the gain or loss on these hedges is reported as a component of accumulated other comprehensive income in stockholders’ equity, and is reclassified into earnings when the hedged transaction affects earnings. If the transaction being hedged fails to occur, or if a portion of any derivative is ineffective, the gain or loss on the associated financial instrument is recorded immediately in earnings. For derivative instruments used to hedge existing foreign currency denominated assets or liabilities, the gain or loss on these hedges is recorded immediately in earnings to offset the changes in the fair value of the assets or liabilities being hedged.

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 costs of revenues when revenue is recognized. The estimated warranty

Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

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 12 “Commitments and Contingencies”).

Revenue Recognition. KLA-Tencor recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the seller’s price is fixed or determinable, and collectibility is reasonably assured. KLA-Tencor derives revenue from four sources—system sales, spare part sales, service contracts and software license fees. KLA-Tencor recognizes revenue for system sales upon acceptance by the customer that the system has been installed and is operating according to predetermined specifications. This positive affirmation is generally evidenced by an acceptance document signed by the customer. In certain limited cases, KLA-Tencor may recognize revenue without a written acceptance from the customer, as follows:

 

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

 

    When the installation of the system is deemed perfunctory, revenue is recognized upon shipment. The portion of revenue associated with installation is deferred;

 

    When the customer fab has already accepted the same tool, with the same specifications, 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 represents the fair value of installation;

 

    When the system is performing in production or R&D 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;

 

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

Total revenue recognized without a written acceptance from the customer was approximately 4.4%, 6.6% and 4.9% of total revenue for fiscal years 2006, 2005 and 2004, respectively. Shipping charges billed to customers are included in system revenue and the related shipping costs are included in costs of revenues.

KLA-Tencor also allows for multiple element revenue arrangements 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 relative fair value of the undelivered 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 unit of accounting and fulfill the following criteria: (a) the delivered item(s) has value to the customer on a standalone basis; (b) there is objective and reliable evidence of the fair value of the undelivered item(s); and (c) if the arrangement includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in the control of the Company. If the arrangement does not meet all the above criteria, the entire amount of the sales contract is deferred until all elements are accepted by the customer.

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 contract 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, and collectibility is reasonably assured.

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 unspecified software 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. The Company periodically reviews the software element of its systems in accordance with SOP No. 97-2, “Software Revenue Recognition” and Emerging Issues Task Force (“EITF”) No. 03-05, “Applicability of SOP 97-2 to Non-Software Deliverables in an Arrangement Containing More-Than-Incidental Software.”

Trade-in rights are occasionally granted to customers to trade in tools in connection with subsequent purchases. The Company estimates the value of the trade-in right and reduces the revenue of the initial sale.

The deferred system profit balance as of June 30, 2006 and 2005 was $226 million and $212 million, respectively, and equals the amount of system revenue that was invoiced and due on shipment but deferred, less applicable product and warranty costs. KLA-Tencor also defers the fair value of extended service contracts and of non-standard warranty bundled with equipment sales as unearned revenue. The unearned revenue balance was $81 million as of June 30, 2006 and 2005.

Research and Development Costs. Research and development costs are expensed as incurred.

Strategic Development Agreements. Gross engineering, research and development expenses were partially offset by $11 million, $8 million and $11 million in external funding received under certain strategic development programs conducted with several of KLA-Tencor’s customers and government grants in fiscal years 2006, 2005 and 2004, respectively.

Shipping and Handling Costs. Shipping and handling costs are included as a component of cost of sales.

Accounting for Stock-Based Compensation Plans. Prior to July 1, 2005, the Company previously applied Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees,” and its related Interpretations and provided the required pro forma disclosures of Statement of Financial Accounting Standards (“SFAS”) No. 123, “Accounting for Stock-Based Compensation.” In accordance with APB Opinion No. 25, a non-cash, stock-based compensation expense was recognized for any options for which exercise price is below the market price on the actual grant date. The charge for such options is equal to the number of option shares multiplied by the difference between the exercise price and the market price on the actual grant date. That expense should have been amortized over the vesting period of the option. Beginning July 1, 2005, the Company has accounted for stock-based compensation using the provisions of SFAS No. 123(R), “Share-Based Payment.” SFAS No. 123(R) establishes accounting for stock-based awards exchanged for employee services. Accordingly, stock-based compensation cost is measured at grant date, based on the fair value of the award, and is recognized

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

as expense over the employee’s requisite service period. The Company elected to adopt the modified prospective application method as provided by SFAS No. 123(R). Accordingly, during fiscal year 2006, the Company recorded stock-based compensation cost totaling the amount that would have been recognized had the fair value method under SFAS No. 123 been applied since the effective date of SFAS No. 123 for the pre-fiscal 2006 year grants and under SFAS No. 123(R) for the fiscal year 2006 grants.

Advertising Expenses. Advertising costs are expensed as incurred. Advertising expenses for fiscal years 2006, 2005 and 2004 were $5.0 million, $4.6 million and $3.9 million, respectively.

Income Taxes. KLA-Tencor accounts 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. KLA-Tencor has determined that the Company’s 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 the Company’s deferred tax assets, KLA-Tencor could be required to record a valuation allowance against the Company’s deferred tax assets. This would result in an increase to the Company’s tax provision in the period in which the Company determined that the recovery was not probable.

In addition, the calculation of the Company’s tax liabilities involves dealing with uncertainties in the application of complex tax regulations. KLA-Tencor recognized liabilities for anticipated tax audit issues in the U.S. and other tax jurisdictions based on the Company’s estimate of whether, and the extent to which, additional tax payments are probable. If the Company ultimately determines that payment of these amounts is unnecessary, the Company will reverse the liability and recognize a tax benefit during the period in which the Company determines that the liability is no longer necessary. KLA-Tencor will record an additional charge in the Company’s provision for taxes in the period in which the Company determines that the recorded tax liability is less than the Company expects the ultimate assessment to be.

Earnings Per Share. Basic earnings 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 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 presented is the inclusion of the dilutive effect of stock options and restricted stock units.

Variable Interest Entities. FASB Interpretation No. (“FIN”) 46(R) requires that if an entity is the primary beneficiary of a variable interest entity, the assets, liabilities, and results of operations of the variable interest entity should be included in the consolidated financial statements of the entity. KLA-Tencor adopted FIN 46(R) effective March 31, 2004. KLA-Tencor had a minority equity interest in a development stage company for which KLA-Tencor was considered to be the primary beneficiary within the provisions of FIN 46(R). KLA-Tencor consolidated this entity as of March 31, 2004. During the quarter ended December 31, 2004, KLA-Tencor acquired the remaining equity outstanding in this entity. Subsequently, KLA-Tencor transferred the assets of this entity to a limited liability corporation in which a third party acquired a minority interest (see Note 6 “Business Combinations”). The impact of the consolidation did not have a material impact on KLA-Tencor’s financial position or results of operations. KLA-Tencor has concluded that none of the Company’s remaining equity investments are material to the Company’s financial position and do not require consolidation as they are either not variable interest entities or, in the event they are variable interest entities, that KLA-Tencor is not considered to be the primary beneficiary.

Contingencies and Litigation. The Company is subject to the possibility of losses from various contingencies. Considerable judgment is necessary to estimate the probability and amount of any loss from such contingencies. An accrual is made when it is probable that a liability has been incurred or an asset has been impaired and the amount of loss can be reasonably estimated. The Company accrues a liability and charges operations for the estimated costs expected to be incurred over the next twelve months of adjudication or settlement of asserted and unasserted claims existing as of the balance sheet date. See Note 12 to Consolidated Financial Statements “Commitments and Contingencies” for a detailed description.

Reclassifications. The Company has reclassified certain prior period balances to conform to the correct presentation. These reclassifications did not impact any amounts presented in our consolidated balance sheets, consolidated statements of operations, consolidated statements of stockholders’ equity or consolidated statements of cash flows.

Recent Accounting Pronouncements. In September 2006, the SEC staff issued Staff Accounting Bulletin (“SAB”) No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements.” SAB No. 108 was issued in order to eliminate the diversity of practice surrounding how public companies quantify financial statement misstatements. SAB No. 108 requires registrants to quantify the impact of correcting all misstatements using both the “rollover” method, which focuses primarily on the impact of a misstatement on the income statement and is the method currently used by the Company, and the “iron curtain” method, which focuses primarily on the effect of correcting the period-end balance sheet. The use of both of these methods is referred to as the “dual approach” and should be combined with the evaluation of qualitative elements surrounding the errors in accordance with SAB No. 99, “Materiality.” The provisions of

SAB No. 108 are effective for the Company for fiscal years beginning July 1, 2006. The adoption of SAB No. 108 is not expected to have a material impact on the Company’s consolidated financial position, results of operations or cash flows.

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements.” SFAS No. 157 defines fair value, establishes a framework for measuring fair value in accordance with generally accepted accounting principles, and expands disclosures about fair value measurements. The provisions of SFAS No. 157 are effective for the Company for fiscal years beginning July 1, 2008. The Company is evaluating the impact of the provisions of this statement on its consolidated financial position, results of operations and cash flows.

In September 2006, the FASB issued SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans.” SFAS No. 158 requires employers to fully recognize the obligations associated with single-employer defined benefit pension, retiree healthcare and other post-retirement plans in their financial statements. The provisions of SFAS No. 158 are effective for the Company as of the end of the fiscal year ending June 30, 2007. The Company is evaluating the impact of the provisions of this statement on its consolidated financial position, results of operations and cash flows.

In June 2006, the FASB published FIN 48, “Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109” which clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements in accordance with SFAS No. 109, Accounting for Income Taxes. This Interpretation prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. This Interpretation also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. This Interpretation is effective for the Company in fiscal years beginning July 1, 2007. The Company is evaluating the impact of the provisions of this Interpretation on its consolidated financial position, results of operations and cash flows.

In February 2006, the FASB issued SFAS No. 155, “Accounting for Certain Hybrid Financial Instruments,” an amendment of SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities,” and SFAS No. 140, “Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities.” This Statement permits fair value remeasurement for any hybrid financial instrument that contains an embedded derivative that otherwise would require bifurcation. This Statement is effective for the Company for all financial

instruments acquired or issued after July 1, 2007. The adoption of SFAS No. 155 is not expected to have a material effect on the Company’s consolidated financial position, results of operations or cash flows.

In June 2005, the FASB issued SFAS No. 154, “Accounting Changes and Error Corrections,” a replacement of APB Opinion No. 20, “Accounting Changes,” and SFAS No. 3, “Reporting Accounting Changes in Interim Financial Statements.” SFAS No. 154 changes the requirements for the accounting for and reporting of a change in accounting principle. Previously, most voluntary changes in accounting principles required recognition via a cumulative effect adjustment within net income of the period of the change. SFAS No. 154 requires retrospective application to prior periods’ financial statements, unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. SFAS No. 154 is effective for the Company for accounting changes made in fiscal years beginning July 1, 2006; however, the Statement does not change the transition provisions of any existing accounting pronouncements. The adoption of SFAS No. 154 is not expected to have a material effect on the Company’s consolidated financial position, results of operations or cash flows.

In March 2005, the FASB published FIN 47, “Accounting for Conditional Asset Retirement Obligations,” which clarifies that the term, conditional asset retirement obligation, as used in SFAS No. 143, “Accounting for Asset Retirement Obligations,” refers to a legal obligation to perform an asset retirement activity in which the timing and (or) method of settlement are conditional on a future event that may or may not be within the control of the entity. The uncertainty about the timing and (or) method of settlement of a conditional asset retirement obligation should be factored into the measurement of the liability when sufficient information exists. The Interpretation also clarifies when an entity would have sufficient information to reasonably estimate the fair value of an asset retirement obligation. The adoption of this Interpretation did not have a material effect on the Company’s consolidated financial position, results of operations or cash flows.

In December 2004, the FASB issued SFAS No. 153, “Exchanges of Nonmonetary Assets,” an amendment of APB Opinion No. 29. SFAS No. 153 addresses the measurement of exchanges of nonmonetary assets and redefines the scope of transactions that should be measured based on the fair value of the assets exchanged. SFAS No. 153 was effective for the Company for nonmonetary asset exchanges beginning in the first quarter of fiscal 2006. The adoption of SFAS No. 153 did not have a material effect on the Company’s consolidated financial position, results of operations or cash flows.

In November 2004, the FASB issued SFAS No. 151, “Inventory Costs,” an amendment of Accounting Research Bulletin (“ARB”) No. 43, Chapter 4. SFAS No. 151 clarifies that abnormal inventory costs such as costs of idle facilities, excess freight and handling costs, and wasted materials (spoilage) are required to be recognized as current period charges. The provisions of SFAS No.151 are effective for the Company for fiscal years beginning July 1, 2005. The adoption of SFAS No. 151 did not have a material impact on the Company’s consolidated financial position, results of operations or cash flows.

NOTE 2—RESTATEMENTS OF CONSOLIDATED FINANCIAL STATEMENTS AND SPECIAL COMMITTEE AND COMPANY FINDINGS

Special Committee Investigation of Historical Stock Option Practices

On May 22, 2006, the Wall Street Journal published an article about stock option backdating that questioned the stock option practices at several companies, including KLA-Tencor. On May 23, 2006, the Company received a subpoena from the United States Attorney’s Office for the Northern District of California (“USAO”) and a letter of inquiry from the United States Securities and Exchange Commission (“SEC”) regarding the Company’s stock option practices. Later on May 23, 2006, the Board of Directors appointed a Special Committee composed solely of independent directors to conduct a comprehensive investigation of the Company’s historical stock option practices. The Special Committee promptly engaged independent legal counsel and accounting experts to assist with the investigation. The investigation included an extensive review of the Company’s

Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

historical stock option practices, accounting policies, accounting records, supporting documentation, email communications and other documentation, as well as interviews of a number of current and former directors, officers and employees. On September 27, 2006, the Special Committee reported the bulk of its findings and recommendations to the Board of Directors.

Findings and Remedial Actions

On September 28, 2006, the Company announced that it would have to restate its previously issued financial statements to correct its past accounting for stock options. As a result of the Special Committee investigation, the Company discovered that certain of its stock options, primarily those granted from July 1, 1997 to June 30, 2002, had been retroactively priced for all employees who received these grants. This means that the option exercise price was not the market price of the option shares on the actual grant date of the option, but instead was a lower market price on an earlier date. The actual grant date—when the essential actions necessary to grant the option were completed, including the final determination of the number of shares to be granted to each employee and the exercise price—is the correct measurement date to determine the market price of the option shares under the accounting rules in effect at the time. More than 95% of the total in-the-money value (market price on the actual grant date minus exercise price) of all of the Company’s retroactively priced options was attributable to those granted from July 1, 1997 to June 30, 2002.

The Company previously applied Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees,” and its related Interpretations and provided the required pro forma disclosures under Statement of Financial Accounting Standards (“SFAS”) No. 123, “Accounting for Stock-Based Compensation,” through its fiscal year ended June 30, 2005. Under APB Opinion No. 25, a non-cash, stock-based compensation expense was required to be recognized for any option for which the exercise price was below the market price on the actual grant date. Because each of the Company’s retroactively priced options had an exercise price below the market price on the actual grant date, there should have been a non-cash charge for each of these options under APB Opinion No. 25 equal to the number of option shares, multiplied by the difference between the exercise price and the market price on the actual grant date. That expense should have been amortized over the vesting period of the option. Starting in its fiscal year ended June 30, 2006, the Company adopted SFAS No. 123(R), “Share-Based Payment.” As a result, beginning in fiscal year 2006, the additional stock-based compensation expense required to be recorded for each retroactively priced option is equal to the incremental fair value of the option on the actual grant date, amortized over the remaining vesting period of the option. The Company did not record these stock-based compensation expenses under APB Opinion No. 25 or SFAS No. 123(R) related to its retroactively priced options in the Company’s previously issued financial statements, and that is why the Company is restating them in this filing. To correct the Company’s past accounting for stock options, it recorded additional pre-tax, non-cash, stock-based compensation expense of (a) $348 million for the periods July 1, 1994 to June 30, 2005 under APB Opinion No. 25 and (b) $22 million for the year ended June 30, 2006 under SFAS No. 123(R). The Company expects to amortize an additional $6 million of such pre-tax charges under SFAS No. 123(R) in future periods to properly account for past retroactively priced stock options.

By October 16, 2006, the Special Committee had substantially completed its investigation. The Special Committee concluded that (1) there was retroactive pricing of stock options granted to all employees who received options, primarily during the periods from July 1, 1997 to June 30, 2002 (less than 15% of these options were granted to executive officers), (2) the retroactively priced options were not accounted for correctly in the Company’s previously issued financial statements, (3) the retroactive pricing of options was intentional, not inadvertent or through administrative error, (4) the retroactive pricing of options involved the selection of fortuitously low exercise prices by certain former executive officers, and other former executives may have been aware of this conduct, (5) the retroactive pricing of options involved the falsification of Company records, resulting in erroneous statements being made in financial and other reports previously filed with the SEC, as well

as in information previously provided to the Company’s independent registered public accounting firm, and (6) in most instances, the retroactive pricing of options violated the terms of the Company’s stock option plans. Because virtually all holders of retroactively priced options issued by the Company were not involved in or aware of the retroactive pricing, the Board of Directors decided that the Company should continue to honor the options that violated the terms of the Company’s stock option plans, except in certain individual cases as described below.

The Special Committee concluded that, with a few immaterial exceptions, the retroactive pricing of stock options stopped after June 30, 2002. After that time, there were procedures in place designed to provide reasonable assurance that stock options were priced on the grant date. The Special Committee also concluded that none of the Company’s independent Directors was involved in or aware of the retroactive pricing of stock options. Based on the Special Committee’s report, the Board of Directors concluded that no current members of management were involved in the retroactive pricing of stock options. During its investigation of the Company’s historical stock option practices, the Special Committee did not find evidence of any other financial reporting or accounting issues.

As a result of the Special Committee investigation, on October 16, 2006, the Company terminated its employment relationship and agreement with Kenneth L. Schroeder, and the Company announced its intent to cancel all outstanding stock options held by Mr. Schroeder that were retroactively priced or otherwise improperly granted. Those options were canceled in December 2006. Mr. Schroeder was the Company’s Chief Executive Officer and a member of its Board of Directors from mid-1999 until January 1, 2006, and was a member of the Company’s stock option committee from 1994 until December 31, 2005. From January 1 to October 16, 2006, Mr. Schroeder was employed as a Senior Advisor to the Company. On November 10, 2006, Mr. Schroeder’s counsel informed the Company that Mr. Schroeder contests the Company’s right to terminate his employment relationship and agreement and to cancel any of his options. The Company intends to vigorously defend any claims that may be made by Mr. Schroeder regarding these matters, which could involve a material amount.

Also on October 16, 2006, Stuart J. Nichols, Vice President and General Counsel, resigned. Mr. Nichols and the Company entered into a Separation Agreement and General Release under which Mr. Nichols’ outstanding retroactively priced stock options have been re-priced by increasing the exercise price to the market price of the option shares on the actual grant date. Under SFAS No. 123(R), no incremental charge will be recognized in the financial statements for the quarter ended December 31, 2006.

On October 16, 2006, Kenneth Levy, Founder and Chairman of the Board of Directors of the Company, retired as a director and employee, and was named Chairman Emeritus by the Board of Directors. Mr. Levy and the Company entered into a Separation Agreement and General Release under which Mr. Levy’s outstanding retroactively priced stock options have been re-priced by increasing the exercise price to the market price of the option shares on the actual grant date. Under SFAS No. 123(R), no incremental charge will be recognized in the financial statements for the quarter ended December 31, 2006. Mr. Levy was the Company’s Chief Executive Officer from 1975 until mid-1999 (with the exception of mid-1997 to mid-1998), was a member of the Company’s Board of Directors from 1975 until his retirement, was Chairman of the Board of Directors from 1999 until his retirement, and was a member of the Company’s stock option committee from 1994 until use of that committee was suspended in the fall of 2006.

On December 21, 2006, Jon D. Tompkins resigned as a director of the Company, and the Company agreed to modify the outstanding options held by Mr. Tompkins (all of which were fully vested) to extend the post-termination exercisability period to December 31, 2007, which is the last day of the calendar year in which those options would have terminated in the absence of such extension. Mr. Tompkins, the Chief Executive Officer of Tencor Instruments before its merger into the Company in mid-1997, was the Company’s Chief Executive

Officer from mid-1997 to mid-1998, was a member of the Company’s stock option committee from mid-1997 until mid-1999, and was a member of the Company’s Board of Directors from mid-1997 until his resignation.

Although the Board of Directors concluded that John H. Kispert, the Company’s President and Chief Operating Officer, was not involved in and was not aware of the improper stock option practices, based on the Special Committee’s recommendation, his outstanding retroactively priced options have been re-priced because he served as Chief Financial Officer during part of the period in question. This re-pricing involved increasing the exercise price to the market price of the option shares on the actual grant date. Under SFAS No. 123(R), no incremental charge will be recognized in the financial statements for the quarter ended December 31, 2006.

Restatement and Impact on Financial Statements

In addition to restating the consolidated financial statements in response to the Special Committee’s findings, the Company is recording additional non-cash adjustments that were previously considered to be immaterial relating primarily to the accounting for employee stock purchase plans, corrections for the recognition of deferred tax assets, the release of tax reserves, the timing of revenue recognition, gains and losses on hedging contracts and the calculation of minority interest. The Company has also corrected the classification of certain amounts presented as cash and cash equivalents and marketable securities relating to investments in Variable Rate Demand Notes. For the fiscal years ended June 30, 2004 and prior, the Company previously recorded no stock-based compensation expense; therefore, the additional stock-based compensation expense noted below represents the total stock-based compensation expense for these periods. For the year ended June 30, 2005, the Company recorded $2.9 million of stock-based compensation with a related tax benefit of $1.1 million in its previously reported financial statements. For fiscal 2005, total stock-based compensation was $37.0 million with a related tax benefit of $12.1 million. The income statement impact of the restatement is as follows (in thousands):

The Company adopted SFAS No. 123(R) effective July 1, 2005. The grant date fair values of stock options granted prior to fiscal year 2006 were changed as a result of the findings that certain stock option grants were retroactively priced. This change resulted in additional stock-based compensation expense of $22 million and a related tax benefit of $12 million being recognized in fiscal year 2006 under SFAS No. 123(R).

The cumulative effect of the restatements up through June 30, 2003 increased additional paid-in capital by $356 million from $815 million to $1.2 billion, increased deferred stock-based compensation from zero to $130 million, decreased retained earnings by $178 million from $1.4 billion to $1.2 billion, and increased total stockholders’ equity by $49 million from $2.2 billion to $2.3 billion.

Diluted shares in fiscal years 2004 and 2005 also increased as a result of the restatement adjustments to correct the past accounting for stock options that were retroactively priced. The Company uses the treasury stock method to calculate the weighted-average shares used in the diluted EPS calculation. As part of the restatement, the Company revised its treasury stock calculations in accordance with SFAS No. 128, “Earnings Per Share.” These calculations assume that (i) all retroactively priced options are exercised, (ii) the Company repurchases shares with the proceeds of these hypothetical exercises along with the tax benefit resulting from the hypothetical exercises, and (iii) any unamortized deferred stock-based compensation is also used to repurchase shares.

In addition, the Company evaluated the impact of the restatements on its global tax provision. The Company and its subsidiaries file tax returns in multiple tax jurisdictions around the world. In certain jurisdictions, including, but not limited to, the United States and the United Kingdom, the Company is able to claim a tax deduction relative to stock options. In those jurisdictions, where a tax deduction is claimed, the Company has recorded deferred tax assets, totaling $51.6 million at June 30, 2005, to reflect future tax deductions to the extent the Company believes such assets to be recoverable. The Company also believes that it should not have taken a United States tax deduction in prior years for stock option related amounts pertaining to certain executives under Internal Revenue Code (IRC) Section 162(m). Section 162(m) limits the deductibility of compensation above certain thresholds. The Company has determined that excess deductions were taken on prior tax returns due to the finding that retroactive pricing of certain stock options occurred. As a result, the Company’s tax liabilities have increased by approximately $8 million.

Because virtually all holders of retroactively priced options issued by the Company were not involved in or aware of the retroactive pricing, the Company has taken and intends to take certain actions to deal with the adverse tax consequences that may be incurred by the holders of retroactively priced options. The adverse tax consequences are that retroactively priced stock options vesting after December 31, 2004 (“409A Affected Options”) subject the option holder to a penalty tax under IRC Section 409A (and, as applicable, similar penalty taxes under California and other state tax laws). One such action by the Company is to offer to amend the 409A Affected Options to increase the exercise price to the market price on the actual grant date or, if lower, the market price at the time of the amendment. The amended options would not be subject to taxation under IRC

Section 409A. Under IRS regulations, these option amendments had to be completed by December 31, 2006 for anyone who was an executive officer when he or she received 409A Affected Options; the amendments for non-officers cannot be offered until after this Report is filed and do not need to be completed until December 31, 2007. Another action is to approve bonuses payable to holders of the amended options to compensate them for the resulting increase in their option exercise price. The amount of these bonuses would be effectively repaid to the Company if and when the options are exercised and the increased exercise price is paid (but there is no assurance that the options will be exercised). Finally, the Company intends to compensate certain option holders who have already exercised 409A Affected Options for the additional taxes they incur under IRC Section 409A (and, as applicable, similar state tax laws).

Three of the Company’s option holders were subject to the December 31, 2006 deadline described above. Accordingly, in December 2006, the Company offered to amend the 409A Affected Options held by Mr. Wallace, the Company’s Chief Executive Officer, and two former executive officers to increase the exercise price so that these options will not subject the option holder to a penalty tax under IRC Section 409A. All three individuals accepted the Company’s offer. In addition, the Company agreed to pay each of the three individuals a cash bonus in January 2008 equal to the aggregate increase in the exercise prices for his amended options. For Mr. Wallace, the amount of this bonus is $0.4 million. The Company plans to take similar actions with respect to the outstanding 409A Affected Options granted to non-officers as soon as possible after the filing of this Report. The Company estimates that the total cash payments needed to deal with the adverse tax consequences of retroactively priced options granted to non-officers will be approximately $30 million.

With respect to the individuals whose options were canceled or re-priced by the Company following the Special Committee investigation, no bonuses of the type described above will be paid.

Correction of classification of cash and cash equivalents and marketable securities

In the third quarter of fiscal 2006, the Company corrected the classification of its variable-rate demand notes with reset dates of 90 days or less, moving them from cash equivalents to short-term investments on the Consolidated Balance Sheets. In the third quarter of fiscal 2005, the Company corrected the classification of its auction rate securities, moving them from cash equivalents to short-term investments on the Consolidated Balance Sheets. All Balance Sheets in these consolidated financial statements present Variable Rate Demand Notes as marketable securities.

As a result, the impact on the Consolidated Balance Sheet at June 30, 2005 was as follows:

Cash and cash equivalents

   $ 874,509    $ 663,163
