Part I

Item 1. Business

This Form 10-K contains forward-looking statements that involve risks and uncertainties. Actual results may differ materially from the forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those set forth under Part I, Item 1A. “Risk Factors.”

GENERAL

Mentor Graphics Corporation is a technology leader in electronic design automation (EDA). We provide software and hardware design solutions that enable our customers to develop better electronic products faster and more cost effectively. We market our products and services worldwide, primarily to large companies in the military/aerospace, communications, computer, consumer electronics, semiconductor, networking, multimedia, and transportation industries.

The electronic systems that our customers create with our products include printed circuit boards (PCBs), integrated circuits (ICs), field programmable gate arrays (FPGAs), embedded software solutions, and wire harness systems. Our products are used in the design and development of a diverse set of electronic products, including automotive electronics, video game consoles, digital cameras, cellular telephones, Bluetooth^® devices, medical devices such as automated external defibrillators, smart phones, e-book readers, and netbooks. As silicon manufacturing process geometries shrink, our customers are creating entire electronic systems on a single IC. These are called system-on-chip (SoC) devices. This trend becomes apparent to the everyday consumer as consumer electronics become smaller and more sophisticated. This trend also poses significant opportunities and challenges for the EDA industry.

We were incorporated in Oregon in 1981, and our common stock is traded on The NASDAQ Global Select Market under the symbol “MENT.” Our executive offices are located at 8005 S.W. Boeckman Road, Wilsonville, Oregon 97070-7777. The telephone number at that address is (503) 685-7000. Our website address iswww.mentor.com. Electronic copies of our reports filed with the Securities and Exchange Commission (SEC) are available through our website as soon as reasonably practicable after the reports are filed with the SEC. Our Director Code of Ethics, Standards of Business Conduct, Guidelines for Corporate Disclosure, Corporate Governance Guidelines, and our Audit, Compensation, and Nominating and Corporate Governance Committee Charters are also posted on our website.

PRODUCTS

We design our products to enable engineers to overcome increasingly complex electronic design challenges by improving the accuracy of complex designs and shrinking product time-to-market schedules. When designing electronic hardware, a design engineer’s process is typically as follows:

• Electrical engineers begin the design process by describing and specifying the architectural, behavioral, functional, and structural characteristics of an IC, PCB, or electronic system and components.

• Engineers then create the component designs according to stated specifications.

• Engineers verify the design to reveal defects and then modify the component’s design until it is correct and meets the previously stated specifications.

• Engineers assemble components and test the components and the entire system.

• The system then goes to production. During the manufacturing process, engineers work to identify defective parts and improve yields. “Yields” refer to the percentage of working ICs on a silicon wafer or PCBs working compared to the total of those manufactured.

Scalable Verification

Our Scalable Verification™ tools allow engineers to verify that their complex IC designs function as intended. Functional errors are a leading cause of design revisions that slow down an electronic system’s time-to-market and reduce its profitability. We offer the following digital simulation products:

• Our ModelSim^® software tool is a leading hardware description language (HDL) mixed-language digital simulator that helps hardware designers verify that their IC design functions correctly before the design is completed, and is used for application-specific integrated circuits (ASICs), SoCs, FPGAs, and other IC design verification, as well as verification of entire systems.

3

• Our Questa^® scalable verification platform includes support for HDLs, including System Verilog, simulation, and new verification methodologies including assertions and formal methods. Questa is used for more extended verification of systems and ICs including ASICs, SoCs, and FPGAs.

Along with digital simulation products, we offer analog/mixed-signal simulators. Complex electronic designs often require different types of circuits, such as analog and digital, to work together. An example is a CD or DVD player which uses a digital input and produces an analog output of sounds or images. Our analog/mixed signal simulation products include the Eldo^®, ADVance MS^TM, and ADiT tools.

We provide hardware emulation systems, such as our Veloce^® product, which allow users to create functional and logical equivalent models of actual electronic circuits to verify the function and timing of those circuits. Hardware emulation systems typically allow faster verification of complex electronic circuits when compared to software simulation tools. Our Veloce product allows customers to verify complex designs containing up to 512 million logic gates.

IC Design to Silicon

Shrinking geometries and increasing design size in the nanometer era have enabled ever increasing functionality on a single IC. A nanometer (nm) is one billionth of a meter; a human hair is about 100,000 nm thick. Feature sizes of today’s advanced ICs are typically less than 100 nm. Nanometer process geometries create design challenges in the creation of ICs which are not present at larger geometries. As a result, nanometer process technologies, used to deliver the majority of today’s ICs, are the product of careful design and precision manufacturing. The increasing complexity and smaller size of designs have changed how those responsible for the physical layout of an IC design deliver their design to the IC manufacturer. In older technologies, this handoff was a relatively simple layout database check when the design went to manufacturing. Now it is a multi-step process where the layout database is modified so the design can be manufactured with cost-effective yields of ICs.

To address these challenges, we offer our Calibre^® tool family, which is a standard for many of the world’s largest integrated device manufacturers and foundries:

• The Calibre physical verification tool suite, Calibre DRC^TM and Calibre LVS^TM, helps ensure that a particular IC layout accurately corresponds to the original schematic or circuit diagram of the design and conforms to stringent manufacturing rules at wafer fabs where ICs are manufactured.

• The Calibre xRC™ product, a transistor-level extraction and device modeling tool, computes the values of detailed circuit parameters including interconnect resistances, capacitances, and inductances to enable customers to more accurately simulate the performance of a design before it is manufactured.

• Calibre lithography tools allow engineers to model, enhance, and verify layouts using lithography resolution enhancement techniques, including optical and process correction, phase-shift mask, scattering bars, and off-axis illumination. Use of these tools can substantially increase the yields of ICs.

• In the Design For Manufacturing (DFM) area, the Calibre LFD™ product can help customers produce higher yields at nanometer process geometries where variations in manufacturing can cause yield reductions. Calibre CMPAnalyzer™ allows customers to model the expected planarity (i.e., thickness variation) of ICs and identify where modifications to the layout will improve a chip’s flatness. This helps prevent manufacturing defects and reduces variations in performance from one chip to the next.

• Calibre PERC™ is a tool for checking the electrical design of an IC. It is useful in verifying for the completeness of electrostatic discharge protection circuitry which affects both manufacturing yield and long-term reliability of an IC.

We also offer the Olympus-SoC™ place and route product targeted at customers designing ICs using geometries of 65 nm and below. The Olympus-SoC product addresses IC design challenges such as manufacturing variability, design size and complexity, and low power requirements. The Olympus-SoC place and route solution addresses these issues with technology such as Design Rule Checkers-, DFM-, power-aware routing, lithography-friendly layout, and multi-corner multi-mode timing analysis, which concurrently optimizes for timing, power, and signal integrity across multiple process corners and design modes.

Integrated System Design

As ICs grow in complexity and function and PCB fabrication technology advances to include embedded components and high-density interconnect layers within the PCB, the design of PCBs is increasingly complex. This complexity can be a source of design bottlenecks.

Our PCB-FPGA Systems Design software products support the PCB design process from schematic entry, where the electronic circuit is defined by engineers, through physical layout of the PCB, to providing digital output data for manufacturing, assembly, and test. Most types of designs, including analog, radio frequency, and high-speed digital and mixed signal, are supported by our PCB design tools. We have specific integrated software tool flows for process management, component library creation, simulation, and verification of the PCB design:

• The Board Station^® and Expedition^TM series are our two main PCB design families of products used typically by large enterprise customers.

• We also offer a “ready to use” PADS^® product line which provides a lower cost Windows-based PCB design and layout solution.

• Our I/O Designer ^TM product integrates FPGA input/output planning with our PCB design tools to help improve routing in large complex designs.

• XtremePCB^TM offers a method for simultaneous design where multiple designers can edit the same design at the same time and view each others’ edits in real-time.

• XtremeAR^TM is a PCB routing product that improves the routing time of large designs. This product allows improved designs by running more routing iterations during the design cycle.

Our AutoActive^® place and route technology is available on both UNIX and Windows platforms and is used to replace older generation routers in our PCB design flows. The AutoActive technology, which is incorporated into both the Board Station and Expedition product lines, is intended to help improve design quality, shorten design cycles, and increase manufacturability. Our Hyperlynx^® high-speed design technology tools address signal integrity and timing challenges of complex, high-speed PCB designs.

We created our Precision^® Synthesis product family which allows a designer to use HDL descriptions of functionality to program the FPGA to perform a specific set of functions.

Our Mechanical Analysis Division offers a line of products that provide simulation of mechanical engineering design processes involving heat transfer and fluid flow which help reduce costs, eliminate design mistakes, and accelerate design cycle time.

New and Emerging Products

Engineers are trying to reduce the design and verification complexity associated with next generation applications found in broadband wireless, image/video processing, and military products. One response to this trend is leading designers toward methodologies based on ANSI C/C++ language which can offer a more abstract and efficient way to create and verify designs. Our Catapult^® C Synthesis tool can help engineering teams to produce ASIC or FPGA hardware that can be smaller in size, use less power, reduce overall design cycle time, and reduce overall verification effort.

Our Integrated Electrical Systems Division provides specialized software for design, analysis, manufacture, and data management of complex wire harness systems used by automotive, aerospace, and other industries. We also offer a variety of software tools targeting the automotive market that focus on the functional design of the electronic components of cars.

We offer a suite of products for companies developing embedded software for products such as smart phones and medical devices. Our offerings in this area are real-time operating systems, middleware, and associated development tools.

We also offer tools to test IC designs. Our Tessent ™ suite of integrated silicon test products are used to test a design’s logic and memories after manufacturing to ensure that a manufactured IC is functioning correctly. Our suite of tools includes scan insertion, automatic test pattern generation, logic and memory built-in self-test, and our patented TestKompress^® product for Embedded Deterministic Test (EDT^TM). A suite of test analysis products is also available that leverages test data and layout-aware diagnosis capabilities for silicon debug and yield analysis.

PLATFORMS

Our software products are available on UNIX, Windows, and LINUX platforms in a broad range of price and performance levels. Customers purchase platforms from leading workstation and personal computer suppliers.

MARKETING AND CUSTOMERS

Our sales and marketing emphasizes large corporate account penetration in the military/aerospace, communications, computer, consumer electronics, semiconductor, networking, multimedia, and transportation industries. We license our products worldwide through our direct sales force, distributors, and sales representatives. During the year ended January 31, 2010, revenues outside of North America accounted for 57% of total revenues compared to 61% for fiscal 2009 and 55% for fiscal 2008. See “Geographic Revenues Information” in Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the footnotes to our financial statements included in Part II, Item 8. “Financial Statements and Supplementary Data” for more information. We enter into foreign currency exchange contracts in an effort to help mitigate the impact of foreign currency fluctuations.

We segregate revenues into five categories of similar products and services. These categories include IC Design to Silicon, Integrated System Design, Scalable Verification, New and Emerging Products, and Services and Other. Each category includes both product and support revenues. See the discussion in Note 22. “Segment Reporting” in Part II, Item 8. “Financial Statements and Supplementary Data” for further detail of revenue by product and service category.

No material portion of our business is dependent on a single or a few customers. We do not believe that the loss of any one or a few of our customers would have a material adverse effect on our revenues. We have traditionally experienced some seasonal fluctuations of orders, with orders typically stronger in the fourth quarter of each year. Due to the complexity of our products, the selling cycle can be three to six months or longer. During the selling cycle our account managers, application engineers, and technical specialists make technical presentations and product demonstrations to the customer. At some point during the selling cycle, our products may also be loaned to customers for short-term on-site evaluation. We generally ship our products to customers within 180 days after receipt of an order and a substantial portion of quarterly shipments tend to be made in the last month of each quarter. We license our products and some third-party products pursuant to end-user license agreements.

BACKLOG

Our backlog of firm orders was approximately $71 million as of January 31, 2010 compared to $69 million as of January 31, 2009. This backlog includes products requested for delivery within six months and unfulfilled professional services and training requested for delivery within one year. We do not track backlog for support services. The January 31, 2010 backlog of orders is expected to ship before the end of our fiscal year ending January 31, 2011.

MANUFACTURING OPERATIONS

Our manufacturing operations primarily consist of reproduction of our software and documentation. In North America, manufacturing is substantially outsourced with distribution to North American and Japanese customers occurring primarily from Wilsonville, Oregon. Our line of emulation products, which has a large hardware component, is manufactured in the United States and France on an outsourced basis. Mentor Graphics (Ireland) Limited, a wholly owned subsidiary of Mentor Graphics Corporation, manufactures, or contracts with third-parties to manufacture, our products and distributes these products to markets outside North America and Japan through our established sales channels. See the discussion in Note 22. “Segment Reporting” in Part II, Item 8. “Financial Statements and Supplementary Data” for further detail of the location of property, plant, and equipment.

PRODUCT DEVELOPMENT

Our research and development is focused on continued improvement of our existing products and the development of new products. During the year ended January 31, 2010, we expensed $256 million related to product research and development compared to $260 million for fiscal 2009 and $248 million for fiscal 2008. We also seek to expand existing product offerings and pursue new lines of business through acquisitions. During the year ended January 31, 2010, we expensed purchased technology and in-process research and development of $12 million compared to $34 million for fiscal 2009 and $14 million for fiscal 2008. Our future success depends on our ability to develop or acquire competitive new products that satisfy customer requirements.

CUSTOMER SUPPORT AND CONSULTING

We have a worldwide support organization to meet our customers’ needs for software support, hardware support, and customer training. Most of our customers enter into support contracts that deliver regular software updates with the latest improvements, technical assistance from experienced experts, access to a self-service support site, and participation in Mentor’s interactive communities. Hardware support is available for emulation products. Mentor Graphics Education Services offers a wide range of learning solutions developed specifically for electronics designers and engineers.

Mentor Consulting, our professional services division, is comprised of a worldwide team of consulting professionals. The services provided to customers are concentrated around our products. In addition, Mentor Consulting provides methodology development and refinement services that help customers improve their product development processes.

COMPETITION

The markets for our products are characterized by price competition, rapid technological advances in application software, and new market entrants. The EDA industry tends to be labor intensive rather than capital intensive. This means that the number of actual and potential competitors is significant. While our two principal competitors are large companies with extensive capital and marketing resources, we also compete with small companies with little capital but innovative ideas. Our principal competitors are Cadence Design Systems, Inc. and Synopsys, Inc.

We believe the main competitive factors affecting our business are breadth and quality of application software, product integration, ability to respond to technological change, quality of a company’s sales force, price, size of the installed base, level of customer support, and professional services. We can give no assurance, however, that we will have financial resources, marketing, distribution and service capability, depth of key personnel, or technological knowledge to compete successfully in our markets.

EMPLOYEES

We employed approximately 4,400 people full time as of January 31, 2010. Our future success will depend in part on our ability to attract and retain employees. None of our United States (U.S.) employees are covered by collective bargaining agreements. Employees in some jurisdictions outside the U.S. are represented by local or national union organizations. We continue to have satisfactory employee relations.

PATENTS AND LICENSES

We regard our products as proprietary and protect our rights in our products and technology in a variety of ways. We currently hold approximately 420 U.S. and 100 non-U.S. patents on inventions embodied in our products or that are otherwise relevant to EDA technology. In addition, we hold approximately 460 patent applications pending in the U.S. and abroad. While we believe the patent applications relate to patentable technology, we cannot predict whether any patent will issue on a pending application, nor can we assure that any patent can be successfully defended.

We also rely on contractual and technical safeguards to protect our proprietary rights in our products. We typically include restrictions on disclosure, use, and transferability in our agreements with customers and other parties. In addition, we use our trademark, copyright, and trade secret rights to protect our interests in our products and technology.

Some of our products include software or other intellectual property licensed from other parties. We also license software from other parties for internal use. We may have to seek new licenses or renew these licenses in the future.

Item 1A. Risk Factors

The forward-looking statements contained under “Outlook for Fiscal 2011” in Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and all other statements contained in this report that are not statements of historical fact, including without limitation, statements containing the words “believes,” “expects,” “projections,” and words of similar meaning, constitute forward-looking statements that involve a number of risks and uncertainties that are difficult to predict. Moreover, from time to time, we may issue other forward-looking statements. Forward-looking statements regarding financial performance in future periods, including the statements under “Outlook for Fiscal 2011,” do not reflect potential impacts of mergers or acquisitions or other significant transactions or events that have not been announced as of the time the statements are made. Actual outcomes and results may differ materially from what is expressed or forecast in forward-looking

7

statements. We disclaim any obligation to update forward-looking statements to reflect future events or revised expectations. Our business faces many risks, and set forth below are some of the factors that could cause actual results to differ materially from the results expressed or implied by our forward-looking statements. Forward-looking statements should be considered in light of these factors.

Weakness in the United States (U.S.) and international economies may harm our business.

Our revenue levels are generally dependent on the level of technology capital spending, which includes worldwide expenditures for electronic design automation (EDA) software, hardware, and consulting services. The global economy continues to be weak, with continuing uncertainty in the credit markets and banking systems, reduced capital spending, and significant job losses. This volatility and uncertainty about future economic conditions could adversely affect our customers and postpone decisions to license or purchase our products, decrease our customers’ spending, and jeopardize or delay our customers’ ability or willingness to make payment obligations, any of which could adversely affect our business. We cannot predict the duration of the global economic downturn or subsequent recovery.

Our forecasts of our revenues and earnings outlook may be inaccurate.

Our revenues, particularly new software license revenues, are difficult to forecast. We use a “pipeline” system, a common industry practice, to forecast revenues and trends in our business. Sales personnel monitor the status of potential business and estimate when a customer will make a purchase decision, the dollar amount of the sale, and the products or services to be sold. These estimates are aggregated periodically to generate a sales pipeline. Our pipeline estimates may prove to be unreliable either in a particular quarter or over a longer period of time, in part because the “conversion rate” of the pipeline into contracts can be very difficult to estimate and requires management judgment. A variation in the conversion rate could cause us to plan or budget incorrectly and materially adversely impact our business or our planned results of operations. In particular, a slowdown in customer spending or weak economic conditions generally can reduce the conversion rate in a particular quarter as purchasing decisions are delayed, reduced in amount, or cancelled. The conversion rate can also be affected by the tendency of some of our customers to wait until the end of a fiscal quarter in an attempt to obtain more favorable terms.

Our business could be impacted by fluctuations in quarterly results of operations due to customer seasonal purchasing patterns, the timing of significant orders, and the mix of licenses and products purchased by our customers.

We have experienced, and may continue to experience, varied quarterly operating results. Various factors affect our quarterly operating results and some of these are not within our control, including customer demand and the timing of significant orders. We typically experience seasonality in demand for our products, due to the purchasing cycles of our customers, with revenues in the fourth quarter generally being the highest. If planned contract renewals with large customers are delayed or the average size of renewed contracts do not increase as we anticipate, we could fail to meet our and investors’ expectations, which could have a material adverse impact on our stock price.

Our revenues are also affected by the mix of licenses entered into where we recognize software revenues as payments become due and payable, on a cash basis, or ratably over the license term as compared to revenues recognized at the beginning of the license term. We recognize revenues ratably over the license term, for instance, when the customer is provided with rights to unspecified or unreleased future products. A shift in the license mix toward increased ratable, due and payable, and/or cash-based revenue recognition could result in increased deferral of software revenues to future periods and would decrease current revenues, which could result in us not meeting near-term revenue expectations.

The gross margin on our software is greater than that for our emulation hardware systems, software support, and professional services. Therefore, our gross margin may vary as a result of the mix of products and services sold. We have a significant amount of fixed or relatively fixed costs, such as employee costs and purchased technology amortization, and costs which are committed in advance and can only be adjusted periodically. As a result, a small failure to reach planned revenues would likely have a relatively large negative effect on gross margins and earnings. If anticipated revenues do not materialize as expected, our gross margins and earnings could be materially adversely impacted.

8

We face intense competition in the EDA industry.

Competition in the EDA industry is intense, which can lead to, among other things, price reductions, longer selling cycles, lower product margins, loss of market share, and additional working capital requirements. If our competitors offer significant discounts on certain products, we may need to lower our prices or offer other favorable terms in order to compete successfully. Any such changes would likely reduce margins and could materially adversely impact our operating results. Any broad-based changes to our prices and pricing policies could cause new software license and service revenues to decline or be delayed as the sales force implements and our customers adjust to the new pricing policies. Some of our competitors may bundle certain software products at low prices for promotional purposes or as a long-term pricing strategy. These practices could significantly reduce demand for our products or constrain prices we can charge.

We currently compete primarily with two large companies: Synopsys, Inc. and Cadence Design Systems, Inc. We also compete with numerous smaller companies and compete with manufacturers of electronic devices that have developed their own EDA products internally.

Our international operations and the effects of foreign currency fluctuations expose us to additional risks.

We typically generate about half of our revenues from customers outside the U.S. and we generate approximately one-third of our expenses outside the U.S. Significant changes in currency exchange rates could have an adverse impact on us. In addition, international operations subject us to other risks including longer receivables collection periods, changes in a specific country’s or region’s economic or political conditions, trade protection measures, local labor laws, import or export licensing requirements, loss or modification of exemptions for taxes and tariffs, limitations on repatriation of earnings, and difficulties with licensing and protecting our intellectual property rights.

We derive a substantial portion of our revenues from relatively few product groups.

We derive a substantial portion of our revenues from sales of relatively few product groups and related support services. As such, any factor adversely affecting sales of these products, including the product release cycles, market acceptance, product competition, performance and reliability, reputation, price competition, and economic and market conditions, could harm our operating results.

We are subject to the cyclical nature of the integrated circuit (IC) and electronics systems industries.

Purchases of our products and services are highly dependent upon new design projects initiated by customers in the IC and electronics systems industries. These industries are highly cyclical and are subject to constant and rapid technological change, rapid product obsolescence, price erosion, evolving standards, short product life cycles, and wide fluctuations in product supply and demand. The IC and electronics systems industries regularly experience significant downturns, often connected with, or in anticipation of, maturing product cycles within such companies or decline in general economic conditions. These downturns could cause diminished demand for our products and services.

Customer payment defaults or related issues could adversely affect our financial condition and results of operations.

We have customer payment obligations not yet due that are attributable to software we have already delivered. These customer obligations are typically not cancelable, but will not yield the expected revenue and cash flow if the customer defaults or declares bankruptcy and fails to pay amounts owed. In these cases, we may generally take legal action to recover amounts owed, if warranted. Moreover, existing customers may seek to renegotiate pre-existing contractual commitments due to adverse changes in their own businesses, particularly in the current troubled economic environment. Though we have not, to date, experienced a material level of defaults or renegotiated a material level of pre-existing contractual commitments, any material payment default by our customers or significant reductions in existing contractual commitments could have a material adverse effect on our financial condition and results of operations. These risks may be exacerbated by the global economic environment because our revenue forecasts assume: (i) customers whose payments are recognized as revenue only when paid will make future payments as scheduled, and (ii) customers whose credit ratings and financial circumstances have deteriorated since we originally booked contracts with them will make future payments as scheduled.

9

Customer payment defaults could adversely affect our timing of revenue recognition.

We use fixed-term license agreements as standard business practices with customers we believe are creditworthy. These multi-year, multi-element term license agreements have payments spread over the license term and are typically about three years in length for semiconductor companies and about four years in length for military and aerospace companies. The complexity of these agreements tends to increase the risk associated with collectibility from customers that can arise for a variety of reasons including ability to pay, product dissatisfaction, and disputes. If we are unable to collect under these agreements, our results of operations could be materially adversely impacted. We use these fixed-term license agreements as a standard business practice and have a history of successfully collecting under the original payment terms without making concessions on payments, products, or services. If we no longer had a history of collecting without providing concessions on the terms of the agreements, then revenue would be required to be recognized under U.S. generally accepted accounting principles as the payments become due and payable over the license term. This change could have a material impact on our results.

IC and printed circuit board (PCB) technology evolves rapidly.

The complexity of ICs and PCBs continues to rapidly increase. In response to this increasing complexity, new design tools and methodologies must be invented or acquired quickly to remain competitive. If we fail to quickly respond to new technological developments, our products could become obsolete or uncompetitive, which could materially adversely impact our business.

Errors or defects in our products and services could expose us to liability and harm our reputation.

Our customers use our products and services in designing and developing products that involve a high degree of technological complexity and have unique specifications. Due to the complexity of the systems and products with which we work, some of our products and designs can be adequately tested only when put to full use in the marketplace. As a result, our customers or their end users may discover errors or defects in our software, or the products or systems designed with or manufactured using our tools may not operate as expected. Errors or defects could result in:

• Loss of current customers and loss of, or delay in, revenue and loss of market share;

• Failure to attract new customers or achieve market acceptance;

• Diversion of development resources to resolve the problems resulting from errors or defects; and

• Increased support or service costs.

In addition, we include limited amounts of third-party technology in our products and we rely on those third parties to provide support services to us. Failure of those third parties to provide necessary support services could materially adversely impact our business.

Long sales cycles and delay in customer completion of projects make the timing of our revenues difficult to predict.

We have a lengthy sales cycle. A lengthy customer evaluation and approval process is generally required due to the complexity and expense associated with our products and services. Consequently, we may incur substantial expenses and devote significant management effort and expense to develop potential relationships that do not result in agreements or revenues and may prevent us from pursuing other opportunities. In addition, sales of our products and services is sometimes discretionary and may be delayed if customers delay approval or commencement of projects due to budgetary constraints, internal acceptance review procedures, timing of budget cycles, or timing of competitive evaluation processes.

Disruptions of our indirect sales channel could affect our future operating results.

Our indirect sales channel is comprised primarily of independent distributors. Our relationships with these distributors are important elements of our marketing and sales efforts. Our financial results could be adversely affected if our contracts with distributors were terminated, if our relationships with distributors were to deteriorate, if any of our competitors enter into strategic relationships with or acquire a significant distributor, or if the financial condition of our distributors were to weaken.

Any loss of our leadership position in certain segments of the EDA market could harm our business.

The industry in which we compete is characterized by very strong leadership positions in specific segments of the EDA market. For example, one company may have a large percentage of sales in the physical verification segment of the market while another may have a similarly strong position in mixed-signal simulation. These strong

10

leadership positions can be maintained for significant periods of time as the software is difficult to master and customers are disinclined to make changes once their employees, as well as others in the industry, have developed familiarity with a particular software product. For these reasons, much of our profitability arises from niche areas in which we are the leader. Conversely, it is difficult for us to achieve significant profits in niche areas where other companies are the leaders. If for any reason we lose our leadership position in a niche, we could be materially adversely impacted.

Accounting rules governing revenue recognition are complex and may change.

The accounting rules governing software revenue recognition are complex and have been subject to authoritative interpretations that have generally made it more difficult to recognize software revenues at the beginning of the license period. If this trend continues, new and revised standards and interpretations could materially adversely impact our ability to meet near-term revenue expectations.

We may have additional tax liabilities.

Significant judgments and estimates are required in determining the provision for income taxes and other tax liabilities. Our tax expense may be impacted if our intercompany transactions, which are required to be computed on an arm’s-length basis, are challenged and successfully disputed by the tax authorities. Also, our tax expense could be impacted depending on the applicability of withholding and other taxes on software licenses and related intercompany transactions in certain jurisdictions. In determining the adequacy of income taxes, we assess the likelihood of the positions taken on our tax returns being sustained. The Internal Revenue Service (IRS) and tax authorities in other countries where we do business regularly examine our tax returns, and such examinations could result in adverse outcomes. The ultimate outcome of these examinations cannot be predicted with certainty. Should the IRS or other tax authorities assess additional taxes as a result of examinations, we may be required to record charges to operations that could have a material impact on the results of operations, financial position, or cash flows.

Forecasting our income tax rate is complex and subject to uncertainty.

The computation of income tax expense (benefit) is complex as it is based on the laws of numerous taxing jurisdictions and requires significant judgment on the application of complicated rules governing accounting for tax provision under U.S. generally accepted accounting principles. Income tax expense (benefit) for interim quarters is based on a forecast of our global tax rate for the year, which includes forward looking financial projections, including the expectations of profit and loss by jurisdiction, and contains numerous assumptions. Various items cannot be accurately forecasted, and may be treated as discrete accounting. Examples of items which could cause variability in the rate include tax deductions for stock option expense, application of transfer pricing rules and changes in our valuation allowance for deferred tax assets. Future events, such as changes in our business and the tax law in the jurisdictions where we do business, could also affect our rate. For these reasons, our global tax rate may be materially different than our forecast.

There are limitations on the effectiveness of controls.

We do not expect that disclosure controls or internal control over financial reporting will prevent all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. Failure of our control systems to prevent error or fraud could materially adversely impact us.

We may not realize revenue as a result of our investments in research and development.

We incur substantial expense to develop new software products. Research and development activities are often performed over long periods of time. This effort may not result in a successful product offering. As a result, we could realize little or no revenue related to our investment in research and development.

We may acquire other companies and may not successfully integrate them.

The industry in which we compete has experienced significant consolidation in recent years. During this period, we have acquired numerous businesses and we may acquire other businesses in the future. While we expect to carefully analyze all potential transactions before committing to them, we cannot assure that any transaction that is

11

completed will result in long-term benefits to us or our shareholders or that we will be able to manage the acquired businesses effectively. In addition, growth through acquisition involves a number of risks. If any of the following events occurs after we acquire another business, it could materially adversely impact us:

• Difficulties in combining previously separate businesses into a single unit;

• The substantial diversion of management’s attention from ongoing business when integrating the acquired business;

• The discovery after the acquisition has been completed of previously unknown liabilities assumed with the acquired business;

• The failure to realize anticipated benefits, such as cost savings and increases in revenues;

• The failure to retain key personnel of the acquired business;

• Difficulties related to assimilating the products of an acquired business in, for example, distribution, engineering, and customer support areas;

• Unanticipated costs;

• Unanticipated litigation in connection with or as a result of an acquisition, including claims from terminated employees, customers, or third parties;

• Adverse impacts on existing relationships with suppliers and customers; and

• Failure to understand and compete effectively in markets in which we have limited experience.

Acquired businesses may not perform as projected, which could result in impairment of acquisition-related intangible assets. Additional challenges include integration of sales channels, training and education of the sales force for new product offerings, integration of product development efforts, integration of systems of internal controls, and integration of information systems. Accordingly, in any acquisition there will be uncertainty as to the achievement and timing of projected synergies, cost savings, and sales levels for acquired products. All of these factors could impair our ability to forecast, meet revenues and earnings targets, and manage effectively our business for long-term growth. We cannot assure that we can effectively meet these challenges.

We may not adequately protect our proprietary rights or we may fail to obtain software or other intellectual property licenses.

Our success depends, in large part, upon our proprietary technology. We generally rely on patents, copyrights, trademarks, trade secret laws, licenses, and restrictive agreements to establish and protect our proprietary rights in technology and products. Despite precautions we may take to protect our intellectual property, we cannot assure that third parties will not try to challenge, invalidate, or circumvent these protections. The companies in the EDA industry, as well as entities and persons outside the industry, are obtaining patents at a rapid rate. Many of these entities have substantially larger patent portfolios than we have. As a result, we may on occasion be forced to engage in costly patent litigation to protect our rights or defend our customers’ rights. We may also need to settle these claims on terms that are unfavorable; such settlements could result in the payment of significant damages or royalties, or force us to stop selling or redesign one or more products. We cannot assure that the rights granted under our patents will provide us with any competitive advantage, that patents will be issued on any of our pending applications, or that future patents will be sufficiently broad to protect our technology. Furthermore, the laws of foreign countries may not protect our proprietary rights in those countries to the same extent as U.S. law protects these rights in the U.S.

Some of our products include software or other intellectual property licensed from third parties, and we may have to seek new licenses or renew existing licenses for software and other intellectual property in the future. Failure to obtain software or other intellectual property licenses or rights from third parties on favorable terms could materially adversely impact us.

Our use of “open source” software could negatively impact our ability to sell our products and subject us to possible litigation.

The products or technologies we acquire, license or develop may incorporate so-called “open source” software, and we may incorporate open source software into other products in the future. Such open source software is generally licensed by its authors or other third parties under open source licenses, including, for example, the GNU General Public License, the GNU Lesser General Public License, and other open source licenses. We monitor our use of open source software in an effort to avoid subjecting our products to conditions we do not intend. Although we believe that we have complied with our obligations under the various applicable licenses for

12

open source software that we use such that we have not triggered any of these conditions, there is little or no legal precedent governing the interpretation of many of the terms of these types of licenses. As a result, the potential impact of these terms on our business may result in unanticipated obligations regarding our products and technologies, such as requirements that we offer our products that use the open source software for no cost, that we make available source code for modifications or derivative works we create based upon, incorporating or using the open source software, and/or that we license such modifications or derivative works under the terms of the particular open source license. In addition to risks related to license requirements, usage of open source software can lead to greater risks than use of third-party commercial software, as open source licensors generally do not provide warranties or assurance of title or controls on the origin of the software.

Our failure to attract and retain key employees may harm us.

We depend on the efforts and abilities of our senior management, our research and development staff, and a number of other key management, sales, support, technical, and services personnel. Competition for experienced, high-quality personnel is intense, and we cannot assure that we can continue to recruit and retain such personnel. Our failure to hire and retain such personnel could impair our ability to develop new products and manage our business effectively.

We have global sales and research and development offices in parts of the world that are not as politically stable as the United States.

We have global sales and research and development offices, some of which are in parts of the world that are not as politically stable as the United States. As a result, we may face a greater risk of business interruption as a result of terrorist acts or military conflicts than businesses located domestically.

Oregon law may have anti-takeover effects.

The Oregon Control Share Act and the Business Combination Act limit the ability of parties who acquire a significant amount of voting stock to exercise control over us. These provisions may have the effect of lengthening the time required to acquire control of us through a proxy contest or the election of a majority of the Board of Directors. The provisions of the Oregon Control Share Act and the Business Combination Act could have the effect of delaying, deferring, or preventing a change of control of us, could discourage bids for our common stock at a premium over the market price of our common stock and could materially adversely impact the market price of, and the voting and other rights of the holders of, our common stock.

We have a substantial level of indebtedness.

As of January 31, 2010, we had $236 million of outstanding indebtedness, which includes $32 million of Floating Rate Convertible Subordinated Debentures (Floating Rate Debentures) due 2023, $165 million of 6.25% Convertible Subordinated Debentures (6.25% Debentures) due 2026, and $38 million in short-term borrowings. This level of indebtedness among other things could:

• Make it difficult for us to satisfy our payment obligations on our debt;

• Make it difficult for us to incur additional indebtedness or obtain any necessary financing in the future for working capital, capital expenditures, debt service, acquisitions, or general corporate purposes;

• Limit our flexibility in planning for or reacting to changes in our business;

• Reduce funds available for use in our operations;

• Make us more vulnerable in the event of a downturn in our business;

• Make us more vulnerable in the event of an increase in interest rates if we must incur new debt to satisfy our obligations under the Floating Rate Debentures and 6.25% Debentures; and

• Place us at a possible competitive disadvantage relative to less leveraged competitors and competitors that have greater access to capital resources.

If we experience a decline in revenues, we could have difficulty paying amounts due on our indebtedness. Any default under our indebtedness could have a material adverse impact on our business, operating results, and financial condition.

13

Our stock price is volatile, and your investment could lose value.

All of the factors discussed in this section could affect our stock price. The timing of announcements in the public market regarding new products, product enhancements, or technological advances by our competitors or us, and any announcements by us of acquisitions, major transactions, or management changes could also affect our stock price. Our stock price is subject to speculation in the press and the analyst community, changes in recommendations or earnings estimates by financial analysts, changes in investors’ or analysts’ valuation measures for our stock, our credit ratings, and market trends unrelated to our performance. A significant drop in our stock price could also expose us to the risk of securities class actions lawsuits, which could result in substantial costs and divert management’s attention and resources, which could adversely affect our business.

Our revolving credit facility has financial and non-financial covenants, and default of any covenant could materially adversely impact us.

Our bank revolving credit facility imposes operating restrictions on us in the form of financial and non-financial covenants. Financial covenants include adjusted quick ratio, minimum tangible net worth, leverage ratio, senior leverage ratio, and minimum cash and accounts receivable ratio. If we were to fail to comply with the financial covenants and did not obtain a waiver from our lenders, we would be in default under the revolving credit facility and our lenders could terminate the facility and demand immediate repayment of all outstanding loans under the revolving credit facility. The declaration of an event of default could have a material adverse effect on our financial condition. We could also find it difficult to obtain other bank lines or credit facilities on comparable terms.

Item 1B. Unresolved Staff Comments

None.

Item 2. Properties

We own six buildings on 43 acres of land in Wilsonville, Oregon. We occupy approximately 405,000 square feet in four of those buildings, as our corporate headquarters. We also own an additional 69 acres of undeveloped land adjacent to our headquarters. Most administrative functions and a significant amount of our domestic research and development operations are located at the Wilsonville site. In January 2010, we purchased three buildings totaling 196,000 square feet in Fremont, California. We plan to relocate all of our San Jose research and development, sales, and administrative operations to Fremont at the termination of the existing San Jose leases in the third quarter of fiscal 2011.

We lease additional space in San Jose, California; Longmont, Colorado; Redmond, Washington; Huntsville and Mobile, Alabama; and Marlboro and Waltham, Massachusetts where some of our domestic research and development takes place; and in various locations throughout the United States and in other countries, primarily for sales and customer service operations. Additional research and development is done in locations outside the United States including locations in Armenia, Egypt, France, India, Pakistan, Poland, Sweden, Finland, Germany, Russia, Hungary, Austria, Taiwan, and the United Kingdom. We believe that we will be able to renew or replace our existing leases as they expire and that our current facilities will be adequate through at least the year ending January  31, 2011.

Item 3. Legal Proceedings

From time to time, we are involved in various disputes and litigation matters that arise from the ordinary course of business. These include disputes and lawsuits relating to intellectual property rights, licensing, contracts, and employee relations matters.

We believe that the outcome of current litigation, individually and in the aggregate, will not have a material effect on our financial position or results of operations.

Item 4. Reserved

None.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Unless otherwise indicated, numerical references included in tables are in thousands, except for percentages and per share data.

OVERVIEW

The following discussion should be read in conjunction with the consolidated financial statements and notes included elsewhere in this Form 10-K. Certain of the statements below contain forward-looking statements. These statements are predictions based upon our current expectations about future trends and events. Actual results could vary materially as a result of certain factors, including but not limited to, those expressed in these statements. In particular, we refer you to the risks discussed in Part I, Item 1A. “Risk Factors” and in our other Securities and Exchange Commission (SEC) filings, which identify important risks and uncertainties that could cause our actual results to differ materially from those contained in the forward-looking statements.

We urge you to consider these factors carefully in evaluating the forward-looking statements contained in this Form 10-K. All subsequent written or spoken forward-looking statements attributable to our company or persons acting on our behalf are expressly qualified in their entirety by these cautionary statements. The forward-looking statements included in this Form 10-K are made only as of the date of this Form 10-K. We do not intend, and undertake no obligation, to update these forward-looking statements.

THE COMPANY

We are a supplier of electronic design automation (EDA) systems — advanced computer software and emulation hardware systems used to automate the design, analysis, and testing of electronic hardware and embedded systems software in electronic systems and components. We market our products and services worldwide, primarily to large companies in the military/aerospace, communications, computer, consumer electronics, semiconductor, networking, multimedia, and transportation industries. Through the diversification of our customer base among these various customer markets, we attempt to reduce our exposure to fluctuations within each market. We sell and license our products through our direct sales force and a channel of distributors and sales representatives. In addition to our corporate offices in Wilsonville, Oregon, we have sales, support, software development, and professional service offices worldwide.

We focus on products and design platforms where we have leading market share, thus enabling us to spend more effort to cause adoption of our technology in new applications, especially for new markets in which EDA companies have not participated. We believe this strategy leads to a more diversified product and customer mix and can help reduce volatility of business, credit risk, and competition, while increasing the potential for growth. System customers make up a much larger percentage of our business than that of most of our EDA competitors.

We derive system and software revenues primarily from the sale of term software license contracts, which are typically three to four years in length. We generally recognize revenue for these arrangements upon product delivery at the beginning of the license term. Larger enterprise-wide customer contracts, which typically represent as much as 50% of our system and software revenue, drive the majority of our period-to-period revenue variances. We identify term licenses where collectibility is not probable and recognize revenue on those licenses when cash is received. Additionally, ratable license revenues also include short-term term licenses as well as other term licenses where we provide the customer with rights to unspecified or unreleased future products. For these reasons, the timing of large contract renewals, customer circumstances, and license terms are the primary drivers of revenue changes from period to period, with revenue changes also being driven by new contracts and increases in the capacity of existing contracts, to a lesser extent.

The EDA industry is highly competitive and is characterized by very strong leadership positions in specific segments of the EDA market. These strong leadership positions can be maintained for significant periods of time as the software can be difficult to master and customers are disinclined to make changes once their employees, as well as others in the industry, have developed familiarity with a particular software product. For these reasons, much of our profitability arises from niche areas in which we are the leader. We will continue our strategy of developing high quality tools with number one market share potential, rather than being a broad-line supplier with undifferentiated product offerings. This strategy allows us to focus investment in areas where customer needs are greatest and we have the opportunity to build significant market share.

Our products and services are dependent to a large degree on new design projects initiated by customers in the integrated circuit and electronics system industries. These industries can be cyclical and are subject to constant and rapid technological change, rapid product obsolescence, price erosion, evolving standards, short product life

19

cycles, and wide fluctuations in product supply and demand. Furthermore, extended economic downturns can result in reduced funding for development due to downsizing and other business restructurings. These pressures are offset by the need for the development and introduction of next generation products once an economic recovery occurs.

Our revenue has historically fluctuated quarterly and has generally been the highest in the fourth quarter of our fiscal year due to our customers’ corporate calendar year-end spending trends and the timing of contract renewals.

Known Trends and Uncertainties Impacting Future Results of Operations

In the United States (U.S.) and abroad, market and economic conditions have been volatile over the past two years, with tighter credit conditions, market volatility, diminished expectations for the U.S. and global economies, and market uncertainty and instability in both U.S. and international capital and credit markets.

As a result of these market conditions, the cost and availability of credit has been and may continue to be adversely affected by illiquid credit markets and wider credit spreads. Many lenders and institutional investors reduced, and in some cases, ceased to provide funding to borrowers due to the absence of a securitization market and concerns about the stability of the markets generally and the strength of the counterparties specifically. Continued turbulence in the U.S. and international markets and economies may adversely affect our liquidity and financial condition, and the liquidity and financial condition of our customers. If these market conditions continue, they may limit our ability, and the ability of our customers, to access the capital markets to meet liquidity needs and timely refinance maturing liabilities, resulting in an adverse effect on our financial condition and results of operations.

The semiconductor industry is particularly vulnerable in this economy as several of the largest companies lack the balance sheet strength that they have historically carried into recessions. Consistent with our revenue recognition policy, when individual customer credit worthiness declines to a level where we do not consider collectibility probable, we convert new transactions from up-front revenue recognition to cash-based revenue recognition and we may be required to modify the payment terms to meet the customer’s ability to pay. Our top ten accounts make up approximately 40% of our receivables, including both short and long-term balances, and we have not experienced and do not presently expect to experience collection issues with these customers. Net of reserves, we have no receivables greater than 60 days past due, and continue to experience no difficulty in factoring our receivables.

Bad debt expense recorded for the year ended January 31, 2010 was not material. However, we do have exposures within our receivables portfolio to some of the larger semiconductor companies with weak credit ratings. These receivables balances do not represent a material portion of our portfolio but could have a material adverse effect on earnings in any given quarter, should additional allowances for doubtful accounts be necessary.

We rely on smaller dollar contracts for a material portion of our business. During fiscal 2010 and fiscal 2009, we experienced a decline in these transactions. The timing and extent of recovery of smaller dollar contracts is unknown.

A multi-quarter increase or decrease in service and support revenue can be an early indicator that our business is either strengthening or weakening. We noted a decline in service and support revenues during each quarter of fiscal 2010 compared to comparable quarters of fiscal 2009 driven by a decrease in consulting and training. Our experience is that customers will scale back on the purchase of outsourcing services in times of economic decline or weakness. In the fourth quarter of fiscal 2010, we noted a leveling off in the rate of declined software maintenance renewals.

Bookings during the year ended January 31, 2010 improved by approximately 5% compared to fiscal 2009. Bookings are the value of executed orders during a period for which revenue has been or will be recognized within six months for products and within twelve months for professional services and training. The ten largest transactions for fiscal 2010 and fiscal 2009 accounted for approximately 40% of total system and software bookings. The number of new customers for fiscal 2010, excluding PADS (our ready to use printed circuit board design tools) and our Flomerics Group, PLC (Flomerics) mechanical analysis tools, decreased approximately 20% from the levels experienced during fiscal 2009.

Product Developments

During the year ended January 31, 2010, we continued to execute our strategy of focusing on challenges encountered by customers, as well as building upon our well-established product families. We believe that customers, faced with leading-edge design challenges in creating new products, generally choose the best EDA products in each category to build their design environment. Through both internal development and strategic acquisitions, we have focused on areas where we believe we can build a leading market position or extend an existing leading market position.

20

We believe that the development and commercialization of EDA software tools is generally a three to five year process with limited customer adoption and sales in the first years of tool availability. Once tools are adopted, however, their life spans tend to be long. We introduced new products and upgrades to existing products during fiscal 2010. During the year ended January 31, 2010, we did not have any significant products reaching the end of their useful economic life.

CRITICAL ACCOUNTING POLICIES

We base our discussion and analysis of our financial condition and results of operations upon our consolidated financial statements which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, and contingencies as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. We evaluate our estimates on an on-going basis. We base our estimates on historical experience, current facts, and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of revenue, costs, and expenses that are not readily apparent from other sources. As future events and their effects cannot be determined with precision, actual results could differ from those estimates.

We believe that the accounting for revenue recognition, valuation of trade accounts receivable, valuation of deferred tax assets, income tax reserves, goodwill, intangible assets, long-lived assets, special charges, and accounting for stock-based compensation are the critical accounting estimates and judgments used in the preparation of our consolidated financial statements. For further information on our significant accounting policies, see Note 2. “Summary of Significant Accounting Policies” in Part II, Item 8. “Financial Statements and Supplementary Data.”

Revenue Recognition

We report revenue in two categories based upon how the revenue is generated: (i) system and software and (ii) service and support.

System and software revenues – We derive system and software revenues from the sale of licenses of software products, emulation hardware systems, and finance fee revenues from our long-term installment receivables resulting from product sales. We primarily license our products using two different license types:

1. Term licenses – We use this license type primarily for software sales. This license type provides the customer with the right to use a fixed list of software products for a specified time period, typically three years, with payments spread over the license term, and does not provide the customer with the right to use the products after the end of the term. Term license arrangements may allow the customer to share products between multiple locations and remix product usage from the fixed list of products at regular intervals during the license term. We generally recognize product revenue from term license arrangements upon product delivery and start of the license term. In a term license agreement where we provide the customer with rights to unspecified or unreleased future products, we recognize revenue ratably over the license term. Revenue from emulation hardware system sales is generally recognized upon delivery.

2. Perpetual licenses – We use this license type for software and emulation hardware system sales. This license type provides the customer with the right to use the product in perpetuity and typically does not provide for extended payment terms. We generally recognize product revenue from perpetual license arrangements upon product delivery assuming all other criteria for revenue recognition have been met.

We include finance fee revenues from the accretion on the discount of long-term installment receivables in System and software revenues.

Service and support revenues – We derive service and support revenues from software and hardware post-contract maintenance or support services and professional services, which include consulting, training, and other services. We recognize revenue ratably over the support services term. We record professional service revenue as the services are provided to the customer.

21

We apply Financial Accounting Standards Board (FASB) guidance applicable to software revenue recognition to all software and hardware product revenue transactions where the software is not incidental. We determine whether product revenue recognition is appropriate based upon the evaluation of whether the following four criteria have been met:

1. Persuasive evidence of an arrangement exists – Generally, we use either a customer signed contract or qualified customer purchase order as evidence of an arrangement for both term and perpetual licenses. For professional service engagements, we generally use a signed professional services agreement and a statement of work to evidence an arrangement. Sales through our distributors are evidenced by an agreement governing the relationship, together with binding purchase orders from the distributor on a transaction-by-transaction basis.

2. Delivery has occurred – We generally deliver software and the corresponding access keys to customers electronically. Electronic delivery occurs when we provide the customer access to the software. We may also deliver the software on a compact disc. With respect to emulation hardware systems, we transfer title to the customer upon shipment. We offer non-essential installation services for emulation hardware systems sales or the customer may elect to perform the installation without our assistance. Our software license and emulation hardware system agreements generally do not contain conditions for acceptance.

3. Fee is fixed or determinable – We assess whether a fee is fixed or determinable at the outset of the arrangement, primarily based on the payment terms associated with the transaction. We have established a history of collecting under the original contract with installment terms without providing concessions on payments, products, or services. Additionally, for installment contracts, we determine that the fee is fixed or determinable if the arrangement has a payment schedule that is within the term of the licenses and the payments are collected in equal or nearly equal installments, when evaluated on a cumulative basis. If the fee is not deemed to be fixed or determinable, we recognize revenue as payments become due and payable.

Significant judgment is involved in assessing whether a fee is fixed or determinable. We must also make these judgments when assessing whether a contract amendment to a term arrangement (primarily in the context of a license extension or renewal) constitutes a concession. Our experience has been that we are able to determine whether a fee is fixed or determinable for term licenses. If we no longer were to have a history of collecting under the original contract without providing concessions on term licenses, revenue from term licenses would be required to be recognized when payments under the installment contract become due and payable. Such a change could have a material impact on our results of operations.

4. Collectibility is probable – To recognize revenue, we must judge collectibility of the arrangement fees on a customer-by-customer basis pursuant to our credit review process. We typically sell to customers with whom there is a history of successful collection. We evaluate the financial position and a customer’s ability to pay whenever an existing customer purchases new products, renews an existing arrangement, or requests an increase in credit terms. For certain industries for which our products are not considered core to the industry or the industry is generally considered troubled, we impose higher credit standards. If we determine that collectibility is not probable based upon our credit review process or the customer’s payment history, we recognize revenue as payments are received.

Multiple element arrangements – For multiple element arrangements, vendor-specific objective evidence of fair value (VSOE) must exist to allocate the total fee among all delivered and non-essential undelivered elements of the arrangement. If undelivered elements of the arrangement are essential to the functionality of the product, we defer revenue until the essential elements are delivered. If VSOE does not exist for one or more non-essential undelivered elements, we defer revenue until such evidence does exist for the undelivered elements, or until all elements are delivered, whichever is earlier. If VSOE of all non-essential undelivered elements exists but VSOE does not exist for one or more delivered elements, we recognize revenue using the residual method. Under the residual method, we defer revenue related to the undelivered elements based upon VSOE and we recognize the remaining portion of the arrangement fee as revenue for the delivered elements, assuming all other criteria for revenue recognition have been met. If we could no longer establish VSOE for non-essential undelivered elements of multiple element arrangements, we would defer revenue until all elements are delivered or VSOE is established for the undelivered elements, whichever is earlier.

We base our VSOE for certain product elements of an arrangement upon the pricing in comparable transactions when the element is sold separately. We primarily base our VSOE for term and perpetual support services upon customer renewal history where the services are sold separately. We also base VSOE for professional services and installation services for emulation hardware systems upon the price charged when the services are sold separately.

Valuation of Trade Accounts Receivable

We maintain allowances for doubtful accounts on Trade accounts receivable and Term receivables, long-term for estimated losses resulting from the inability of our customers to make required payments. We regularly evaluate the collectibility of our trade accounts receivable based on a combination of factors. When we become aware of a

22

specific customer’s inability to meet its financial obligations, such as in the case of bankruptcy or deterioration in the customer’s operating results, financial position, or credit rating, we record a specific reserve for bad debt to reduce the related receivable to the amount believed to be collectible. We also record unspecified reserves for bad debt for all other customers based on a variety of factors including length of time the receivables are past due, the financial health of the customers, the current business environment, and historical experience. Current economic conditions we have considered include forecasted spending in the semiconductor industry, consumer spending for electronics, integrated circuit research and development spending, and volatility in gross domestic product. If these factors change or circumstances related to specific customers change, we adjust the estimates of the recoverability of receivables resulting in either additional selling expense or a reduction in selling expense in the period such determination is made.

Valuation of Deferred Tax Assets

Deferred tax assets are recognized for deductible temporary differences, net operating loss carryforwards, and credit carryforwards if it is more likely than not that the tax benefits will be realized. We have considered future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for valuation allowances. We have recorded a valuation allowance to reduce our deferred tax assets to the amount that is more likely than not to be realized. In the event we determine that we would be able to realize our deferred tax assets in the future in excess of our net recorded amount, we would reverse the valuation allowance associated with such deferred tax assets in the period such determination was made. Further, deferred tax assets are not recorded to the extent they are directly associated with uncertain tax positions. Also, if we were to determine that we would not be able to realize all or part of our net deferred tax assets in the future, we would charge an adjustment to increase the valuation allowance on such net deferred tax assets to expense in the period such determination was made.

Income Tax Reserves

We are subject to income taxes in the U.S. and in numerous foreign jurisdictions; in the ordinary course of business there are many transactions and calculations where the ultimate tax determination is uncertain. We have reserves for taxes to address potential exposures involving tax positions that are being challenged or that could be challenged by taxing authorities even though we believe the positions we have taken are appropriate. We review the tax reserves as circumstances warrant and adjust the reserves as events occur that affect our potential liability for additional taxes.

We recognize a tax position when we determine that it is more likely than not that the position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. For tax positions that are more likely than not to be sustained, we measure the tax position at the largest amount of benefit that has a greater than 50 percent likelihood of being realized when it is effectively settled. We follow the applicable FASB guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition with respect to tax positions. We reflect interest and penalties related to income tax liabilities as income tax expense.

Goodwill, Intangible Assets, and Long-Lived Assets

We review long-lived assets, including intangible assets with definite lives, for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may not be recoverable. We assess the recoverability of our long-lived assets by determining whether their carrying values are greater than the forecasted undiscounted net cash flows of the related assets. If we determine the assets are impaired, we write down the assets to their estimated fair value. We determine fair value based on forecasted undiscounted net cash flows or appraised values, depending upon the nature of the assets. Significant management judgment is required in the forecasts of future operating results that are used in the undiscounted cash flow method of valuation. The estimates we have used are consistent with the plans and estimates that we use to manage our business. It is possible, however, that the plans may change and estimates used may prove to be inaccurate. If our actual results, or the plans and estimates used in future impairment analyses, are lower than the original estimates used to assess the recoverability of these assets, we could incur impairment charges.

We test goodwill for impairment at least annually and whenever events or changes in circumstances indicate an impairment may exist. The value of our intangible assets, including goodwill, could be impacted by future adverse changes such as: (i) any future declines in our operating results, (ii) a decline in the valuation of technology company stocks, (iii) a further significant slowdown in the worldwide economy or the semiconductor industry, or (iv) any failure to meet the performance projections included in our forecasts of future operating results. In the event that we determine that our goodwill, intangible assets, or other long-lived assets are impaired, we make an adjustment that results in a charge to earnings for the write-down in the period that determination is made.

23

Special Charges

We record restructuring charges within Special charges in the Consolidated Statements of Operations in connection with our plans to better align our cost structure with projected operations in the future. We have recorded restructuring charges in connection with employee rebalances based on estimates of the expected costs associated with severance benefits. If the actual cost incurred exceeds the estimated cost, an addition to Special charges will be recognized. If the actual cost is less than the estimated cost, a benefit to Special charges will be recognized.

We have also recorded restructuring charges in connection with excess leased facilities to offset future rent, net of estimated sublease income that could be reasonably obtained. Additionally, we also write-off leasehold improvements on abandoned office space. We work with external real estate experts in each of the markets where properties are located to develop assumptions used to determine a reasonable estimate of the net loss. Our estimates of expected sublease income could change based on factors that affect our ability to sublease those facilities such as general economic conditions and the local real estate market. If the real estate markets worsen and we are not able to sublease the properties as expected, an addition to Special charges will be recognized in the period such determination is made. Likewise, if the real estate market strengthens and we are able to sublease the properties earlier or at more favorable rates than projected, a benefit to Special charges will be recognized.

Accounting for Stock-Based Compensation

We measure stock-based compensation cost at the grant date, based on the fair value of the award, and recognize the expense on a straight-line basis over the employee’s requisite service period. For options and stock awards that vest fully on any termination of service, there is no requisite service period and consequently we recognize the expense fully in the period in which the award is granted.

We estimate the fair value of stock options and purchase rights under our employee stock purchase plans using a Black-Scholes option-pricing model. The Black-Scholes option-pricing model incorporates several highly subjective assumptions including expected volatility, expected term, and interest rates.

In reaching our determination of expected volatility for options we include the following elements:

• Historical volatility of our shares of common stock;

• Historical volatility of shares of comparable companies;

• Implied volatility of our traded options; and

• Implied volatility of traded options of comparable companies.

In reaching our determination of expected volatility for purchase rights under our employee stock plans, we use the historical volatility of our shares of common stock.

We base the expected term of our stock options on historical experience.

The risk-free interest rate for periods within the contractual life of the award is based on the U.S. Treasury yield curve in effect at the time of the grant.

The fair value of the restricted stock units is the market value as of the grant date.

The input factors used in the valuation model are based on subjective future expectations combined with management judgment. If there is a difference between the assumptions used in determining stock-based compensation cost and the actual factors which become known over time, we may change the input factors used in determining stock-based compensation costs. These changes may materially impact the results of operations in the period such changes are made. In addition, if we were to modify any awards, additional charges would be taken.

RECENT BUSINESS COMBINATIONS

During the year ended January 31, 2010, we made a number of acquisitions. For each acquisition, the excess of the fair value of the consideration transferred over the fair value of the net tangible assets acquired and net tangible liabilities assumed was allocated to various identifiable intangible assets and goodwill. Identifiable intangible assets typically consist of technology and customer-related intangibles, which are amortized to expense over their useful lives. Goodwill, representing the excess of the purchase consideration over the fair value of net tangible and identifiable intangible assets, is not amortized.

24

Acquisitions during the year ended January 31, 2010

Acquisition	Total Consideration Transferred		Net Tangible Assets Acquired		Identifiable Intangible Assets Acquired		Deferred Tax Liability			Goodwill
LogicVision, Inc.	$	15,352	$	1,151	$	7,470	$	–		$	6,731
Other		9,310		190		2,490		(222	)		6,852
	$	24,662	$	1,341	$	9,960	$	(222	)	$	13,583

On August 18, 2009, we acquired all of the outstanding common shares of LogicVision, Inc. (LogicVision), a test and yield learning company in the semiconductor design-for-test sector. The acquisition was an investment aimed at extending our product offerings within the EDA industry. Under the terms of the purchase agreement, LogicVision shareholders received 0.2006 of a share of our common stock for each LogicVision common share. Accordingly, we issued 1,903 shares of our common stock to the former common shareholders of LogicVision, resulting in consideration transferred for the common stock issued of $14.3 million, at our closing price on August 18, 2009, of $7.51 per share. The purchase agreement also required that we exchange our stock options for LogicVision’s outstanding stock options resulting in additional consideration of $1.1 million, representing the fair value of stock options issued that are attributable to the pre-combination service period. The identified intangible assets acquired consisted of purchased technology of $5.3 million and other intangibles of $2.2 million. The goodwill created by the transaction is not deductible for tax purposes. Key factors that make up the goodwill created by the transaction include expected synergies from the combination of operations, future technologies, and the knowledge and experience of the acquired workforce. We included the results of the LogicVision operations in our consolidated financial statements from the date of acquisition forward.

Other acquisitions for the year ended January 31, 2010 consisted of three privately-held companies, which were not material individually or in the aggregate.

Total system and software revenues	$	479,493	7%		$	447,551	(19%	)	$	555,297

We derive system and software revenues from the sale of licenses of software products and emulation hardware systems, including finance fee revenues from our long-term installment receivables resulting from product sales. Upfront license revenues consist of perpetual licenses and term licenses for which we recognize revenue upon product delivery at the start of the license term. We identify term licenses where collectibility is not probable and recognize revenue on those licenses when cash is received. Additionally, ratable license revenues also include short-term term licenses, term licenses where we provide the customer with rights to unspecified or unreleased future products, and finance fee revenues from the accretion of the discount on long-term installment receivables.

Our top ten customers accounted for approximately 43% of total System and software revenues for fiscal 2010 compared to approximately 36% for fiscal 2009 and 33% for fiscal 2008. The increase for fiscal 2010 from fiscal 2009 was primarily due to two large new transactions increasing revenues by approximately $42.0 million. The decrease for fiscal 2009 from fiscal 2008 was primarily due to a decrease in the number of customers that generated revenues for the period in the amount of $1.0 million or greater, resulting in a decline in System and software revenues of $94.0 million.

For fiscal 2010, fiscal 2009, and fiscal 2008, no single customer accounted for 10% or more of Total revenues. Sales of product associated with our acquisitions in fiscal 2010 and fiscal 2009 resulted in increases in System and software revenues of $13.0 million for fiscal 2010 compared to increases in System and software revenues of $6.2 million for fiscal 2009 that resulted from our fiscal 2009 Flomerics acquisition.

During fiscal 2010, System and software revenues exceeded system and software bookings. Accordingly, our backlog of firm orders for System and software decreased slightly from $55.5 million as of January 31, 2009 to $54.5 million as of January 31, 2010. System and software bookings exceeded System and software revenues during fiscal 2009 as our backlog of firm orders increased from $50.2 million as of January 31, 2008 to $55.5 million as of January 31, 2009.

Foreign currency had an overall unfavorable impact of $1.0 million on Total revenues for fiscal 2010 compared to fiscal 2009, primarily as a result of the weakening of the euro and British pound against the U.S. dollar, partially offset by the strengthening of the Japanese yen against the U.S. dollar. Foreign currency had an overall favorable impact of $14.3 million on our revenues for fiscal 2009 compared to fiscal 2008, primarily as a result of the strengthening of the Japanese yen and euro against the U.S. dollar.

System and software gross margin percentage was flat for fiscal 2010 compared to fiscal 2009. System and software gross margin percentage decreased for fiscal 2009 compared to fiscal 2008 primarily due to increased purchased technology amortization of $2.9 million, primarily from the acquisition of Flomerics.

Amortization of purchased technology to System and software cost of revenues was $12.0 million for fiscal 2010, $12.4 million for fiscal 2009, and $9.5 million for fiscal 2008. The decrease in amortization for fiscal 2010 compared to fiscal 2009 was primarily due to certain

26

purchased technology being fully amortized during fiscal 2010 and fiscal 2009. The increase in amortization for fiscal 2009 compared to fiscal 2008 was primarily due to the additional amortization resulting from the fiscal 2009 Flomerics and Ponte Solutions, Inc. (Ponte) acquisitions of $3.8 million.

Service and Support

We derive service and support revenues from software and hardware post-contract maintenance or support services and professional services, which include consulting, training, and other services. Professional services are a lower margin offering which is staffed according to fluctuations in demand while support services operate under a less variable cost structure resulting in improved margins as revenue increases. The decrease in revenues of $18.3 million for fiscal 2010 compared to fiscal 2009 was primarily the result of the softening of the global economy as our customers scaled back on annual maintenance renewals and purchases of outsourced services. The decrease for fiscal 2010 from fiscal 2009 was partially offset by increased Service and support revenues of $7.5 million resulting from our acquisitions during fiscal 2010 and fiscal 2009.

The increase in service and support revenues of $17.1 million for fiscal 2009 compared to fiscal 2008 was primarily due to the growth in the installed base of customers under support contracts. The increase for fiscal 2009 from fiscal 2008 included increased Service and support revenues of $8.3 million from the fiscal 2009 Flomerics acquisition and the fiscal 2008 Sierra Design Automation, Inc. (Sierra) acquisition.

Service and support gross margin percentage increased for fiscal 2010 compared to fiscal 2009 as decreased costs of $11.7 million more than offset the impact of an $18.3 million reduction in revenues. Lower costs in fiscal 2010 included reductions in outside services, headcount-related costs, travel, and infrastructure expenses.

Service and support gross margin percentage increased for fiscal 2009 compared to fiscal 2008 primarily due to a lower cost base resulting from headcount reductions and the impact of higher revenues discussed above.

For fiscal 2010, approximately one-third of European and substantially all Japanese revenues were subject to exchange fluctuations as they were booked in local currencies. For fiscal 2009, approximately one-fourth of European and approximately ninety percent of Japanese revenues were subject to exchange fluctuations. For fiscal 2008, approximately one-fourth of European and substantially all Japanese revenues were subject to exchange fluctuations. We recognize additional revenues in periods when the U.S. dollar weakens in value against foreign currencies. Likewise, we recognize lower revenues in periods when the U.S. dollar strengthens in value against foreign currencies. The effects of exchange rate differences from foreign currencies to the U.S. dollar were negligible for fiscal 2010 compared to fiscal 2009 and favorably impacted revenues by 2% for fiscal 2009 compared to fiscal 2008.

We incur a substantial portion of our operating expenses outside the U.S. in various foreign currencies. When currencies weaken against the U.S. dollar, our operating expense performance is positively affected and when currencies strengthen, our operating expense performance is adversely affected. For fiscal 2010 compared to fiscal 2009, we experienced favorable currency movements of $19.7 million in total operating expenses. For fiscal 2009 compared to fiscal 2008, we experienced unfavorable currency movements of $10.3 million in total operating expenses. The impact of these currency effects is reflected in the movements in operating expenses detailed above.

Amortization of Intangible Assets

Amortization of intangible assets for fiscal 2010 was unchanged from fiscal 2009 as the amortization of certain intangible assets acquired in acquisitions in fiscal 2010 and fiscal 2009 was offset by the decreased amortization of certain intangible assets acquired in years prior to fiscal 2009.

The increase in amortization of intangible assets for fiscal 2009 compared to fiscal 2008 was primarily due to amortization of certain intangible assets acquired in acquisitions in fiscal 2009 and fiscal 2008. The fiscal 2009 amortization of intangible assets included amortization of intangible assets from the June 2007 Sierra acquisition of $5.9 million and the July 2008 Flomerics acquisition of $1.1 million.

Special Charges

Total special charges	$	21,334	26%		$	16,888	66%	$	10,148

Special charges primarily consist of costs incurred for employee terminations and were due to a reduction of personnel resources driven by modifications of business strategy or business emphasis. Special charges may also include expenses incurred related to potential acquisitions, excess facility costs, and asset-related charges.

Employee severance and related costs of $10.7 million for the year ended January 31, 2010 included severance benefits, notice pay, and outplacement services. The total rebalance charge represents the aggregate of numerous unrelated rebalance plans which impacted several employee groups, none of which was individually material to our financial position or results of operations. We determined termination benefit amounts based on employee status, years of service, and local statutory requirements. We communicated termination benefits to the affected employees prior to the end of the quarter in which we recorded the charge. Approximately 83% of these costs were paid during the year ended January 31, 2010. We expect to pay the remainder during fiscal 2011. There have been no significant modifications to the amount of these charges.

Excess leased facility costs of $2.5 million for the year ended January 31, 2010 were primarily due to the abandonment of leased facilities and changes in the estimate of sublease income for previously abandoned leased facilities.

Acquisition costs of $2.1 million for the year ended January 31, 2010 represent legal and other costs related to acquisitions and potential acquisitions. In accordance with the FASB’s revised guidance on business combinations, we expensed acquisition costs in the period in which the costs were incurred for the year ended January 31, 2010. Prior to fiscal 2010, acquisition costs were included in consideration transferred for the acquisition.

29

Other special charges for the year ended January 31, 2010 included costs of $4.7 million for advisory fees, charges of $0.6 million for a casualty loss, and other charges of $0.7 million.

Employee severance and related costs of $9.8 million for the year ended January 31, 2009 included severance benefits, notice pay, and outplacement services. The total rebalance charge represents the aggregate of numerous unrelated rebalance plans which impacted several employee groups, none of which was individually material to our financial position or results of operations. We determined termination benefit amounts based on employee status, years of service, and local statutory requirements. We communicated termination benefits to the affected employees prior to the end of the quarter in which we recorded the charge. Approximately 93% of these costs were paid as of January 31, 2010. We expect to pay the remainder during fiscal 2011. There have been no significant modifications to the amount of these charges.

Excess leased facility costs of $2.5 million for the year ended January 31, 2009 were primarily due to the abandonment of leased facilities and changes in the estimate of sublease income for previously abandoned leased facilities.

Other special charges for the year ended January 31, 2009 included costs of $4.5 million for advisory fees.

Employee severance and related costs of $9.7 million for the year ended January 31, 2008 included severance benefits, notice pay, and outplacement services. The total rebalance charge represents the aggregate of numerous unrelated rebalance plans which impacted several employee groups, none of which was individually material to our financial position or results of operations. We determined termination benefit amounts based on employee status, years of service, and local statutory requirements. We communicated termination benefits to the affected employees prior to the end of the quarter in which we recorded the charge. Costs remaining as of January 31, 2009 were paid in fiscal 2010.

Excess leased facility costs of $(0.5) million for the year ended January 31, 2008 was primarily due to the reoccupancy of a previously abandoned leased facility and the termination of an abandoned facility lease in a lease buyout. The cost of the lease buyout was less than the remaining balance of the accrual, resulting in an adjustment to special charges.

Other special charges for the year ended January 31, 2008 included costs of $1.0 million related to the abandonment of an information technology project, costs of $0.1 million for the termination of a service agreement related to a subsidiary that was legally merged with one of our other subsidiaries located in the same country, and a benefit of $0.1 million related to a liability arising from a previous acquisition which was favorably settled.

Targeted Reductions for Fiscal 2010

For the year ended January 31, 2010, as part of our planning process we targeted $35.0 million of reductions (inclusive of beneficial foreign currency movements) to our prior year base operating expenses in Research and development, Marketing and selling, and General and administration. We identified and put in action a series of programs to reduce costs. Travel was sharply restricted. We froze wages, curtailed hiring, and selectively reduced employee compensation and benefits. We reduced headcount during fiscal 2010, excluding the impact from acquisitions completed in fiscal 2010 and fiscal 2009. We recognized savings from actions taken in fiscal 2010 associated with employee rebalances included in Special charges.

Base operating expenses (Research and development, Marketing and selling, and General and administration) were down approximately 3% for fiscal 2010 compared to fiscal 2009 as a result of our cost reduction programs and favorable currency movements of approximately $19.7 million for fiscal 2010. These decreases were net of increased operating costs associated with businesses acquired in fiscal 2010 and 2009 which totaled $12.7 million.

We have operations in foreign jurisdictions where the U.S. dollar has strengthened relative to the prior year. Our planned cost savings assumed continued strengthening of the U.S. dollar in most foreign jurisdictions compared to fiscal 2009.

An increase in Research and development, Marketing and selling, and General and administration expenses for fiscal 2010 occurred as a result of acquisitions that were completed in fiscal 2009. Operating costs associated with fiscal 2009 acquisitions increased approximately $7.9 million in fiscal 2010 when compared to fiscal 2009. This increase was the result of a full year of operations in fiscal 2010 versus a partial year of operations in fiscal 2009. Additionally, fiscal 2010 acquisitions increased operating costs by approximately $4.8 million. Fiscal 2010 acquisitions were not contemplated as part of our targeted cost reductions for fiscal 2010.

30

Excluding the effects of increased costs arising from acquisitions completed in fiscal 2010 and fiscal 2009, we realized an overall cost savings of approximately $35.0 million.

Impairment of Long Lived Assets

At January 31, 2009, we completed a review of our long-lived assets for impairment due to the adverse market conditions and declines in our market capitalization. We assessed the recoverability of our long-lived assets by determining whether their carrying values were greater than the forecasted undiscounted net cash flows of the related assets. We determined the assets were impaired and wrote down the assets to their estimated fair value. We determined fair value based on forecasted undiscounted net cash flows or appraised values, depending upon the nature of the assets. For purposes of this evaluation, long-lived assets were grouped with other assets and liabilities at the lowest level for which identifiable cash flows were largely independent of the cash flows of other assets and liabilities. We subdivided long-lived assets into six separate asset groups for impairment testing. The long-lived assets of each group consisted primarily of purchased technology, other intangibles, and property, plant, and equipment. Based on this evaluation, it was determined that one of our asset groups was impaired.

We recorded an impairment loss of $4.6 million during fiscal 2009 for the difference between the carrying value and the fair value of the long-lived assets of this asset group. We used an income approach and forecasted undiscounted net cash flows to determine the fair value of the assets. The impairment was recorded in Operating expenses in our Consolidated Statement of Operations for fiscal 2009. The impaired assets continue to be used in our operations.

In-Process Research and Development

Year ended January 31,	2010		Change		2009		Change		2008
In-process research and development	$	–	(100	%)	$	22,075	438	%	$	4,100

Prior to fiscal 2010, we expensed in-process research and development arising from our acquisitions to Operating expenses in our Consolidated Statement of Operations upon acquisition. Effective February 1, 2009 upon the adoption of revised business combination guidance, in-process research and development is capitalized as an intangible asset as part of the purchase price allocation. Upon completion of the project, in-process research and development will be amortized to Cost of revenues over the life of the product. Alternatively, if the project is abandoned, the in-process research and development costs will be expensed to Operating expense when that determination is made.

In-process research and development of $22.1 million for the year ended January 31, 2009 includes $1.3 million for the Ponte acquisition, $6.8 million for the Flomerics acquisition, and $14.0 million resulting from undeveloped technology acquired through a joint development agreement with IBM. In-process research and development of $4.1 million for fiscal 2008 was assigned entirely to one project, Next Generation Pinnacle, resulting from the Sierra acquisition. The projects included in in-process research and development for the year ended January 31, 2009 are summarized as follows:

Acquisition	Project	Discount Rate		Expected Commercial Feasibility
Flomerics	Next Generation FLOTHERM	22	%	Fiscal 2012
	Next Generation FLOVENT	22	%	Fiscal 2012
	Next Generation MicReD	22	%	Fiscal 2011
Ponte	Litho-Etch	18	%	January 2010

We based the value of the Ponte and Flomerics in-process research and development on the excess earnings method which measures the value of an asset by calculating the present value of related future economic benefits, such as cash earnings. The modeled cash flow was discounted back to net present value and was based on estimates of revenues and operating profits related to the project. Significant assumptions used in the valuation of the Ponte and Flomerics in-process research and development included: stage of development of the project, future revenues, estimated life of the product’s underlying technology, future operating expenses, and a discount rate to reflect the present value and the risk associated with the development of technology. The development of the Litho-Etch project was halted in fiscal 2010 as it is unlikely we will release a product based on this technology.

31

We based the value of the undeveloped technology acquired through the 22 nanometer joint development agreement with IBM on the present value of the four year payment stream as defined in the agreement. The joint development agreement provides access to technology which has not yet reached technological feasibility and provides no alternative future use. The technology is expected to be the basis for a new offering in our Calibre^® product family once development is completed. The product release date has yet to be determined.

We based the value of the Sierra in-process research development on the excess earnings method. The modeled cash flow was discounted back to net present value and was based on estimates of revenues and operating profits related to the project. Significant assumptions used in the valuation of the Sierra in-process research and development included: stage of development of the project, future revenues, estimated life of the product’s underlying technology, future operating expenses, and a discount rate of 20% to reflect present value and the risk associated with the development of technology. The development of the project was completed during fiscal 2009 and the related product is now in production.

The risks associated with the acquired research and development are considered high, and no assurance can be made that any resulting products will generate any benefit or meet market expectations.

Other Income (Expense), Net

Year ended January 31,	2010			Change		2009			Change		2008
Interest income	$	1,003		(80%	)	$	5,107		(27%	)	$	7,001
Foreign currency exchange gain (loss)		(423	)	(109%	)		4,781		629%			(904	)
Impairment of cost-basis investments		(113	)	97%			(3,488	)	–			–
Equity in losses of unconsolidated entities		(995	)	31%			(1,432	)	–			–

Other income (expense), net	$	(928	)	(121%	)	$	4,510		(14%	)	$	5,225

The decrease in interest income for fiscal 2010 compared to fiscal 2009 was due to a decrease in interest income for the time value of foreign currency contracts of approximately $2.1 million as well as the decrease of interest earned on our cash, cash equivalents, and short-term investments of $2.0 million. The decrease in interest earned on cash, cash equivalents, and short term investments resulted from a decrease in the amount of cash held in interest bearing accounts and short-term investments and a decrease in the interest rates earned on interest bearing accounts.

The decrease in interest income for fiscal 2009 compared to fiscal 2008 was primarily the result of a decrease in the amount of cash held in interest bearing accounts and short-term investments and a decrease in the interest rates earned on interest bearing accounts.

The improvement of foreign currency exchange gain for fiscal 2009 compared to fiscal 2008 was primarily due to the favorable movement of exchange rates on the U.S. dollar and unhedged balance sheet positions associated with our acquisition of Flomerics.

In fiscal 2010, we recognized impairment losses on one long-term investment maintained on a cost basis, as we determined that the investment had an other-than-temporary decline in value. In fiscal 2009, we recognized impairment losses on two long-term investments maintained on a cost basis, as we determined that both investments had an other-than-temporary decline in value.

Interest Expense

Year ended January 31,	2010		Change		2009		Change		2008
Interest expense	$	17,546	(9%	)	$	19,354	(22%	)	$	24,726

The decrease in interest expense for fiscal 2010 compared to fiscal 2009 was primarily due to the decrease in interest expense on the time value of foreign currency contracts of approximately $0.9 million and a decrease in interest expense of approximately $0.8 million primarily due to a decrease in the effective interest rate of our Floating Rate Convertible Subordinated Debentures (Floating Rate Debentures) due 2023.

32

The decrease in interest expense for fiscal 2009 compared to fiscal 2008 was due largely to the purchase and retirement during fiscal 2008 of $13.7 million of the Floating Rate Debentures and $35.0 million of the 6.25% Convertible Subordinated Debentures (6.25% Debentures) due 2026.

Provision for Income Taxes

Year ended January 31,	2010		Change		2009		Change		2008
Income tax expense	$	2,248	(79%	)	$	10,850	(62%	)	$	28,556

In the year ended January 31, 2010, our loss before taxes of $19.6 million consisted of $75.9 million of pre-tax loss in the U.S. and $56.3 million of foreign pre-tax income, reflecting the higher proportion of our operating expenses that are incurred in the U.S. Generally, the provision for income taxes is the result of the mix of profits and losses earned by us and our subsidiaries in tax jurisdictions with a broad range of income tax rates, withholding taxes (primarily in certain foreign jurisdictions), changes in tax reserves, and the application of valuation allowances on deferred tax assets. Deferred tax assets consist of net operating loss carryforwards in several jurisdictions, including the U.S., credit carryovers, and timing differences between book and taxable income. A valuation allowance is recorded when it is more likely than not that all or some portion of the deferred tax asset will not be realized.

We have tax expense in the year ended January 31, 2010 even though we have a net loss on our Consolidated Statement of Operations for the fiscal year. This is primarily because we recorded a net profit from international operations, thereby incurring expense while we incurred losses in the U.S. Any tax benefit in the U.S. is generally offset by an increase in the valuation allowance on U.S. deferred tax assets. This inability to utilize the benefits of our U.S. losses is the primary reason for our negative tax rate of 11% for the year ended January 31, 2010. This differs from tax computed at the U.S. federal statutory rate of 35% primarily due to:

• U.S. losses for which no tax benefit has been recognized;

• Non-deductible employee stock purchase plan compensation expense; and

• Withholding taxes in certain foreign jurisdictions;

These differences are partially offset by:

• The benefit of lower tax rates on earnings of foreign subsidiaries;

• Reduction in reserves for uncertain tax positions; and

• The application of tax incentives for research and development in certain jurisdictions.

We have not provided for income taxes on the undistributed earnings of our foreign subsidiaries to the extent they are considered permanently re-invested outside of the U.S. As of January 31, 2010, the cumulative amount of earnings upon which income taxes have not been provided for is approximately $303.6 million. Upon repatriation, some of these earnings may be sheltered by U.S. loss carryforwards or the carryforward of foreign tax credits, which may reduce the federal tax liability associated with any future foreign dividend. To the extent that the earnings of our foreign subsidiaries are not treated as permanently reinvested, which include earnings of certain countries, we have considered the impact in our provision. Determination of the amount of unrecognized deferred U.S. income tax liability is not practicable; however, the potential foreign tax credit associated with the deferred income would be available to reduce the resulting U.S. tax liabilities.

As of January 31, 2010, for federal income tax purposes, we had net operating loss carryforwards of approximately $167.7 million, foreign tax credits of $3.5 million, research and experimentation credit carryforwards of $37.4 million, alternative minimum tax credits of $2.7 million, and childcare credits of $1.1 million. For state income tax purposes, we had net operating loss carryforwards totaling $173.8 million from multiple jurisdictions, and research and experimentation and other miscellaneous state credits of $7.3 million. Portions of our loss carryforwards, inherited through various acquisitions, are subject to annual limitations due to the change in ownership provisions of the Internal Revenue Code. If we do not use the carryforwards to reduce U.S. taxable income in future periods, portions of the net operating loss carryforwards will expire in fiscal years ending 2019 through 2030. The foreign tax credits will expire in fiscal years ending 2015 through 2020, research and experimentation credit carryforwards will expire between fiscal years ending 2011 through 2030, and childcare credits will expire between fiscal years ending 2023 and 2030. The alternative minimum tax credits do not expire. As of January 31, 2010, we have net operating losses in multiple foreign jurisdictions of $13.6 million. In general, we can carry forward the net operating losses for these foreign jurisdictions indefinitely.

33

We determined deferred tax assets and liabilities based on differences between the financial reporting and tax basis of assets and liabilities. We calculated the deferred tax assets and liabilities using the enacted tax rates and laws that will be in effect when we expect differences to reverse. Since 2004, we have determined it is uncertain whether our U.S. entity will generate sufficient taxable income and foreign source income to utilize foreign tax credit carryforwards, research and experimentation credit carryforwards, and net operating loss carryforwards before expiration. Accordingly, we recorded a valuation allowance against those deferred tax assets for which realization does not meet the more likely than not standard. We determine valuation allowances related to certain foreign deferred tax assets based on historical losses as well as future expectations in certain jurisdictions. We will continue to evaluate the realizability of the deferred tax assets on a periodic basis.

Net deferred tax assets of $18.9 million as of January 31, 2010, reflect a net decrease of $14.1 million compared to $33.0 million as of January 31, 2009. Gross deferred tax assets increased by $23.9 million from January 31, 2009 to January 31, 2010 principally due to the generation of net operating losses in the U.S. and the timing of the deduction on the accrued expenses. There was a $4.2 million increase in deferred tax liabilities from January 31, 2009 to January 31, 2010 principally related to our position regarding the earnings of certain jurisdictions that are not treated as permanently reinvested and other intangibles acquired with fiscal year 2010 acquisitions. The valuation allowance increased by $33.8 million from January 31, 2009 to January 31, 2010.

We are subject to income taxes in the U.S. and in numerous foreign jurisdictions. In the ordinary course of business there are many transactions and calculations where the ultimate tax determination is uncertain. The statute of limitations for adjustments to our historic tax obligations will vary from jurisdiction to jurisdiction. In some cases it may be extended or be unlimited. Furthermore, net operating loss and tax credit carryforwards may be subject to adjustment after the expiration of the statute of limitations of the year such net operating losses and tax credits originated. Our larger jurisdictions generally provide for a statute of limitations from three to five years. We are currently under examination in various jurisdictions. The examinations are in different stages and timing of their resolution is difficult to predict. In March 2007, the Internal Revenue Service (IRS) issued a Revenue Agent’s Report for fiscal 2002 through 2004 in which adjustments were asserted totaling $146.6 million of additional taxable income. The adjustments primarily concern transfer-pricing arrangements related to intellectual property rights acquired in acquisitions that were transferred to a foreign subsidiary. During fiscal year 2010, we reached a settlement with the IRS, which was consistent with our expectations and addressed within our reserve position. Further, due to the company’s available losses that could be applied, the settlement did not result in any significant cash outlay. The tax years for U.S. federal income tax purposes that remain open are fiscal year 2006 and forward. The statute of limitations remains open for years on or after 2004 in Japan and 2005 in Ireland.

We have reserves for taxes to address potential exposures involving tax positions that are being challenged or that could be challenged by taxing authorities even though we believe that the positions we have taken are appropriate. We believe our tax reserves are adequate to cover potential liabilities. We review the tax reserves quarterly and as circumstances warrant and adjust the reserves as events occur that affect our potential liability for additional taxes. It is often difficult to predict the final outcome or timing of resolution of any particular tax matter. Various events, some of which cannot be predicted, such as clarification of tax law by administrative or judicial means, may occur and would require us to increase or decrease our reserves and effective tax rate. We expect to record additional reserves in future periods with respect to the company’s tax filing positions. It is reasonably possible that unrecognized tax positions may decrease from $0 to $8.2 million due to settlements or expirations of the statute of limitations within the next twelve months. To the extent that uncertain tax positions resolve in our favor, it could have a positive impact on our effective tax rate. A portion of reserves, which could settle or expire within the next twelve months, may result in the booking of deferred tax assets subject to a valuation allowance for which no benefit would be recognized. Income tax-related interest and penalties were a benefit of $1.6 million for the year ended January 31, 2010 and an expense of $3.1 million for the year ended January 31, 2009.

The liability for income taxes associated with uncertain tax positions was $36.8 million as of January 31, 2010 and $59.1 million as of January 31, 2009. Tax benefits that could offset this liability were $0.6 million as of January 31, 2010 and $2.5 million as of January 31, 2009. Such offsetting tax benefits consider the correlative effects of deductible interest and state income taxes and other deductible tax adjustments. We expect uncertain tax positions of $33.0 million, if recognized, would favorably affect our effective tax rate. As of January 31, 2010, the full reserve for taxes of $36.8 million was reflected in income tax liability.

RECENT ACCOUNTING PRONOUNCEMENTS

The FASB issued guidance in September 2009 setting forth requirements that must be met for an entity to recognize revenue from the sale of a delivered item that is part of a multiple-element arrangement when other items have not been delivered. This guidance eliminates the requirement that all undelivered elements have VSOE or third-party evidence before an entity can recognize the portion of an overall arrangement fee that is attributable to items that have already been delivered. This guidance requires that, in the absence of VSOE or third-party evidence, a company estimate a selling price and that the relative selling prices be used to allocate revenue amongst the elements of a multi-element arrangement, eliminating the use of the residual method. This guidance is effective for fiscal years beginning on or after June 15, 2010, but may be adopted earlier as of the beginning of an interim or fiscal year. The FASB amended this guidance in September 2009 to exclude from its scope tangible products that contain both software and non-software components that function together to deliver a product’s essential functionality. The amended guidance applies to all hardware product revenue transactions. We will adopt this guidance prospectively as of February 1, 2010, the beginning of fiscal 2011, for multi-element arrangements involving our emulation hardware systems. We expect that the adoption of this guidance will have an impact on our consolidated financial statements. The nature and magnitude of the specific effects will depend on the arrangements we enter into with multiple deliverables after the effective date of February 1, 2010.

LIQUIDITY AND CAPITAL RESOURCES

Our primary ongoing cash requirements will be for product development, operating activities, capital expenditures, debt service, and acquisition opportunities that may arise. Our primary sources of liquidity are cash generated from operations and borrowings under our revolving credit facility.

As of January 31, 2010, we had cash and cash equivalents of $99.3 million. The available cash and cash equivalents are held in accounts managed by third-party financial institutions and consist of invested cash and cash in our operating accounts.

Invested cash is held in interest bearing funds managed by third-party financial institutions. To date, we have experienced no loss or lack of access to our invested cash; however, we can provide no assurances that access to our cash and cash equivalents will not be impacted by adverse conditions in the financial markets.

At any point in time, we have significant balances in operating accounts that are with individual third-party financial institutions, which may exceed the Federal Deposit Insurance Corporation insurance limits or other regulatory insurance program limits. While we monitor daily the cash balances in our operating accounts and adjust the cash balances as appropriate, these cash balances could be impacted if the underlying financial institutions fail or are subject to other adverse conditions in the financial markets.

We anticipate that the following will be sufficient to meet our working capital needs on a short-term (twelve months or less) and a long-term (more than twelve months) basis:

• Current cash balances;

• Anticipated cash flows from operating activities, including the effects of selling and financing customer term receivables;

• Amounts available under existing revolving credit facilities; and

• Other available financing sources, such as the issuance of debt or equity securities.

However, capital markets have been volatile, and we cannot assure you that we will be able to raise debt or equity capital on acceptable terms, if at all.

Operating Activities

Cash flows from operating activities consist of our net income (loss), adjusted for certain non-cash items and changes in operating assets and liabilities. Our cash flows from operating activities are significantly influenced by the payment terms on our license agreements and by our sales of qualifying accounts receivable. As a result of the current global economic downturn, our customers may not be able to make future payments as scheduled or may

35

seek to renegotiate pre-existing contractual commitments due to adverse changes in their own businesses. Our customers’ inability to fulfill payment obligations could adversely affect our cash flow. Though we have not, to date, experienced a material level of defaults, material payment defaults by our customers as a result of current economic conditions or otherwise could have a material adverse effect on our financial condition. To address these concerns, we are monitoring our accounts receivable portfolio for customers with low or declining credit ratings and have increased our collection efforts.

Term receivables, long-term	$	164,898	$	146,682
Average days sales outstanding in short-term receivables		110 days		101 days
Average days sales outstanding in trade accounts receivable, net, excluding the current portion of term receivables		42 days		50 days

The increase in the average days sales outstanding in short-term receivables as of January 31, 2010 compared to January 31, 2009 was due to a decrease in revenue in the fourth quarter of fiscal 2010 compared to fiscal 2009. The increase in Trade accounts receivable, net as of January 31, 2010 compared to January 31, 2009 was a result of an increase in large payments received during the fourth quarter of fiscal 2009 compared to fiscal 2010 and an increase in term deals recorded during the fourth quarter of fiscal 2010 compared to fiscal 2009.

The current portion of term receivables was $178.9 million as of January 31, 2010 and $139.1 million as of January 31, 2009. The decrease in average days sales outstanding excluding the current portion of term receivables was due to improved collections during the year ended January 31, 2010.

The current portion of term receivables is attributable to multi-year term license sales agreements. We include amounts for term agreements that are due within one year in Trade accounts receivable, net, and balances that are due in more than one year in Term receivables, long-term. We use term agreements as a standard business practice and have a history of successfully collecting under the original payment terms without making concessions on payments, products, or services although the impact of current economic conditions on our customers could affect this performance. The increase in total term receivables from $285.8 million as of January 31, 2009 to $343.8 million as of January 31, 2010 was primarily a result of an increase in term deals recorded during the fourth quarter of fiscal 2010 compared to fiscal 2009.

We enter into agreements to sell qualifying accounts receivable from time to time to certain financing institutions on a non-recourse basis. We received net proceeds from the sale of receivables of $31.8 million for fiscal 2010 compared to $54.2 million for fiscal 2009. We continue to find no difficulty in securing factoring sources and continue to evaluate the economics of the sale of accounts receivable. We have not set a target for the sale of accounts receivables for fiscal 2011.

Accrued Payroll and Related Liabilities

As of January 31,	2010		2009
Accrued payroll and related liabilities	$	77,008	$	62,453

The increase in Accrued payroll and related liabilities was primarily due to higher variable compensation for fiscal 2010 compared to fiscal 2009.

Investing Activities

Excluding short-term investments, cash used in investing activities for the year ended January 31, 2010 primarily consisted of cash paid for capital expenditures.

Expenditures for property, plant, and equipment increased to $46.4 million for fiscal 2010 compared to $40.4 million for fiscal 2009. The expenditures for property, plant, and equipment were primarily a result of the purchase of three buildings in Fremont, California for $21.2 million in January 2010 offset in part by reduced spending on information technology and infrastructure improvements within facilities.

In fiscal 2010, we acquired LogicVision through the issuance of common stock valued at $14.3 million. Also in fiscal 2010, we acquired three privately-held companies for cash consideration of $9.3 million.

36

We plan to finance our continued investments in property, plant, and equipment using cash. We plan to finance our continued investments in business acquisitions through a combination of cash and common stock issuances. The cash expected to be utilized includes cash on hand, cash generated from operating activities, and borrowings under the revolving credit facility.

Financing Activities

For the year ended January 31, 2010, cash provided by financing activities consisted primarily of $20.0 million provided by common stock issuances resulting from stock option exercises and employee stock plan purchases. This was offset in part by repayments of $3.5 million on the Floating Rate Debentures.

We may elect to purchase or otherwise retire some or all of our debentures with cash, stock, or other assets from time to time in the open market or privately negotiated transactions, either directly or through intermediaries, or by tender offer when we believe that market conditions are favorable to do so. Such purchases may have a material effect on our liquidity, financial condition, and results of operations.

Other factors affecting liquidity and capital resources

6.25% Debentures due 2026

Interest on the 6.25% Debentures is payable semi-annually in March and September. The 6.25% Debentures are convertible, under certain circumstances, into our common stock at a conversion price of $17.968 per share for a total of 9.2 million shares as of January 31, 2010. Upon conversion, in lieu of shares of our common stock, for each $1 thousand principal amount of the 6.25% Debentures a holder will receive an amount of cash equal to the lesser of: (i) $1 thousand or (ii) the conversion value of the number of shares of our common stock equal to the conversion rate. If such conversion value exceeds $1 thousand, we will also deliver, at our election, cash or common stock, or a combination of cash and common stock with a value equal to the excess. If a holder elects to convert their 6.25% Debentures in connection with a fundamental change in the company that occurs prior to March 6, 2011, the holder will also be entitled to receive a make whole premium upon conversion in some circumstances. The 6.25% Debentures rank pari passu with the Floating Rate Debentures. We may redeem some or all of the 6.25% Debentures for cash on or after March 6, 2011. The holders, at their option, may redeem some or all of the 6.25% Debentures for cash on March 1, 2013, 2016, or 2021. During the year ended January 31, 2010, we did not repurchase any 6.25% Debentures and the principal amount of $165.0 million remains outstanding.

Floating Rate Debentures due 2023

Interest on the Floating Rate Debentures is payable quarterly in February, May, August, and November at a variable interest rate equal to 3-month London Interbank Offered Rate (LIBOR) plus 1.65%. The effective interest rate was 2.44% for the year ended January 31, 2010. The Floating Rate Debentures are convertible, under certain circumstances, into our common stock at a conversion price of $23.40 per share, for a total of 1.4 million shares as of January 31, 2010.

The conversion price may be adjusted based on certain future transactions, such as stock splits or stock dividends. We may redeem some or all of the Floating Rate Debentures for cash at 100.81% of the face amount, with the premium reducing to 0% on August 6, 2010. The holders, at their option, may redeem some or all of the Floating Rate Debentures for cash on August 6, 2010, 2013, or 2018. During the year ended January 31, 2010, we purchased on the open market and retired Floating Rate Debentures with a principal balance of $3.8 million at a discount. As a result, a principal amount of $32.3 million was outstanding as of January 31, 2010.

We have reclassified the entire $32.3 of Floating Rate Debentures to short-term in our Consolidated Balance Sheet as of January 31, 2010 as holders, at their option, may redeem some or all of the Floating Rate Debentures for cash on August 6, 2010. We expect to retire this obligation utilizing cash on hand and amounts available under our revolving credit facility.

For further information on our 6.25% Debentures and our Floating Rate Debentures, see Note 10. “Notes Payable” in Part II, Item 8. “Financial Statements and Supplementary Data.”

Revolving Credit Facility

We are party to a syndicated, senior, unsecured, four-year revolving credit facility with a maximum borrowing capacity of $140.0 million with an option to increase the borrowing capacity by an additional $10.0 million in the future. Under this revolving credit facility, we have the option to pay interest based on: (i) LIBOR with varying maturities which are commensurate with the borrowing period we select, plus a spread of between 1.0% and 1.6%, or (ii) a base rate plus a spread of between 0.0% and 0.6%, based on a pricing grid tied to a financial covenant. The base rate is defined as the higher of: (i) the federal funds rate, as defined, plus 0.5%, (ii) the prime rate of the lead bank, or (iii) one-month LIBOR plus 1.0%. As a result of these interest rate options, our interest expense associated with borrowings under this revolving credit facility will vary with market interest rates. In addition,

37

commitment fees are payable on the unused portion of the revolving credit facility at rates between 0.25% and 0.35% based on a pricing grid tied to a financial covenant. We paid commitment fees of $0.4 million for fiscal 2010 and $0.3 million for fiscal 2009.

We borrowed $20.0 million against the revolving credit facility and repaid $20.0 million during the year ended January 31, 2010. As of January 31, 2010, we had an outstanding balance of $20.0 million. The interest rate as of January 31, 2010 was 3.25%.

For further information on our revolving credit facility, see Note 9. “Short-Term Borrowings.”

OFF-BALANCE SHEET ARRANGEMENTS

We do not have off-balance sheet arrangements, financings, or other similar relationships with unconsolidated entities or other persons, also known as special purpose entities. In the ordinary course of business, we lease certain real properties, primarily field sales offices, research and development facilities, and equipment.

CONTRACTUAL OBLIGATIONS

We are contractually obligated to make the following payments as of January 31, 2010:

	Payments due by period
	Total		Less than 1 year		1-3 years		3-5 years		More than 5 years
Convertible subordinated notes	$	197,272	$	32,272	$	–	$	165,000	$	–

Total contractual obligations	$	528,784	$	122,370	$	76,054	$	201,088	$	129,272

(1) Interest on our Floating Rate Debentures was calculated using the rate effective as of January 31, 2010 and is only included in payments due in less than one year.

(2) We did not include $36.8 million of unrecognized tax liability due to the uncertainty with respect to the timing of future cash flows as of January 31, 2010. We are unable to make reasonably reliable estimates of the period of cash settlement with the respective taxing authorities and the total amounts of income tax payable. The timing of such tax payments may depend on the resolution of current and future tax examinations which cannot be estimated.

(3) Other borrowings include amounts due to financial institutions for the sale of receivables.

OUTLOOK FOR FISCAL 2011

We expect revenues for the first quarter of fiscal 2011 to be approximately $180.0 million, with earnings per share for the same period in the range of break-even to a net loss per share of $(0.05).

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

All numerical references in tables are in thousands, except interest rates and contract rates.

INTEREST RATE RISK

We are exposed to interest rate risk primarily through our investment portfolio, short-term borrowings, and notes payable. We do not use derivative financial instruments for speculative or trading purposes.

We place our investments in instruments that meet high quality credit standards, as specified in our investment policy. The policy also limits the amount of credit exposure to any one issuer and type of instrument. We do not expect any material loss with respect to our investment portfolio.

The table below presents the carrying amount and related weighted-average fixed interest rates for our investment portfolio. The carrying amount approximates fair value as of January 31, 2010. In accordance with our investment policy, all short-term investments mature in twelve months or less.

Principal (notional) amounts in United States dollars	Carrying Amount		Average Fixed Interest Rate
Cash equivalents – fixed rate	$	29,800	0.03%
Short-term investments – fixed rate		3	8.25%
Total fixed rate interest bearing instruments	$	29,803	0.03%

We had convertible subordinated debentures of $165.0 million outstanding with a fixed interest rate of 6.25% as of January 31, 2010. For fixed rate debt, interest rate changes affect the fair value of the debentures but do not affect earnings or cash flow.

We had floating rate convertible subordinated debentures of $32.3 million outstanding with a variable interest rate of 3-month London Interbank Offered Rate (LIBOR) plus 1.65% as of January 31, 2010. For variable interest rate debt, interest rate changes generally do not affect the fair market value but do affect earnings and cash flow.

As of January 31, 2010, we had a syndicated, senior, unsecured revolving credit facility, which expires on June 1, 2011. Borrowings under the revolving credit facility are permitted to a maximum of $140.0 million. Under this revolving credit facility, we have the option to pay interest based on: (i) LIBOR with varying maturities which are commensurate with the borrowing period we select, plus a spread of between 1.0% and 1.6%, or (ii) a base rate plus a spread of between 0.0% and 0.6%, based on a pricing grid tied to a financial covenant. The base rate is defined as the higher of: (i) the federal funds rate, as defined, plus 0.5%, (ii) the prime rate of the lead bank, or (iii) one-month LIBOR plus 1.0%. As a result of these interest rate options, our interest expense associated with borrowings under this revolving credit facility will vary with market interest rates. This revolving credit facility contains certain financial and other covenants, including financial covenants requiring the maintenance of specified liquidity ratios, leverage ratios, and minimum tangible net worth as well as restrictions on the payment of cash dividends. As of January 31, 2010, we had $20.0 million outstanding against this revolving credit facility. For variable interest rate debt, interest rate changes generally do not affect the fair market value, but do affect future earnings and cash flows.

We had other short-term borrowings of $4.5 million outstanding as of January 31, 2010 with variable rates based on market indexes. For variable interest rate debt, interest rate changes generally do not affect the fair market value, but do affect future earnings and cash flow.

If the interest rates on the above variable rate borrowings were to increase or decrease by 1% for the year and the level of borrowings outstanding remained constant, annual interest expense would increase or decrease by approximately $0.6 million.

FOREIGN CURRENCY RISK

We transact business in various foreign currencies and have established a foreign currency hedging program to hedge certain foreign currency forecasted transactions and exposures from existing assets and liabilities. Our derivative instruments consist of short-term foreign currency exchange contracts, with a duration period of a year or less. We enter into contracts with counterparties who are major financial institutions and, as such we do not expect material losses as a result of defaults by our counterparties. We do not hold or issue derivative financial instruments for speculative or trading purposes.

39

From time to time, we enter into foreign currency option contracts for forecasted revenues and expenses between our foreign subsidiaries. These instruments provide us the right to sell/purchase foreign currencies to/from third-parties at future dates with fixed exchange rates.

The following table provides volume information about our foreign currency option program. The information provided is in United States (U.S.) dollar equivalent amounts. The table presents the gross notional amounts, at contract exchange rates, and the weighted average contractual foreign currency exchange rates.

As of January 31,	2009
	Gross Notional Amount		Weighted Average Contract Rate
Option Contracts:
Euro	$	97,475	0.66
Japanese yen		60,837	110.68
British pound		31,032	0.52
Total option contracts	$	189,344

We have not entered into any new option contracts subsequent to the first quarter of fiscal 2010 due to a significant increase in option premiums driven by market volatility. The remaining option contracts were fully utilized as of January 31, 2010. As a result, we had no option contracts outstanding as of January 31, 2010.

We enter into foreign currency forward contracts to protect against currency exchange risk associated with expected future cash flows. Our practice is to hedge a majority of our existing material foreign currency transaction exposures, which generally represent the excess of expected euro and British pound expenses over expected euro and British pound denominated revenues, and the excess of Japanese yen denominated revenue over expected Japanese yen expenses. We also enter into foreign currency forward contracts to protect against currency exchange risk associated with existing assets and liabilities.

The following table provides volume information about our foreign currency forward program. The information provided is in U.S. dollar equivalent amounts. The table presents the gross notional amounts, at contract exchange rates, and the weighted average contractual foreign currency exchange rates. These forward contracts mature within the next twelve months.

As of January 31,	2010			2009
	Gross Notional Amount		Weighted Average Contract Rate	Gross Notional Amount		Weighted Average Contract Rate
Forward Contracts:
Euro	$	77,186	0.69	$	56,081	0.75

Notes to Consolidated Financial Statements

All numerical references in thousands, except for employee data, percentages, and per share data.

1. Nature of Operations

We are a supplier of electronic design automation (EDA) systems — advanced computer software and emulation hardware systems used to automate the design, analysis, and testing of electronic hardware and embedded systems software in electronic systems and components. We market our products and services worldwide, primarily to large companies in the military/aerospace, communications, computer, consumer electronics, semiconductor, networking, multimedia, and transportation industries. We sell and license our products through our direct sales force and a channel of distributors and sales representatives. We were incorporated in Oregon in 1981 and our common stock is traded on The NASDAQ Global Select Market under the symbol “MENT.” In addition to our corporate offices in Wilsonville, Oregon, we have sales, support, software development, and professional service offices worldwide.

2. Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include our financial statements and those of our wholly-owned and majority-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

We do not have off-balance sheet arrangements, financings, or other similar relationships with unconsolidated entities or other persons, also known as special purpose entities. In the ordinary course of business, we lease certain real properties, primarily field sales offices, research and development facilities, and equipment, as described in Note 12. “Commitments and Contingencies.”

Foreign Currency Translation

Local currencies are the functional currencies for our foreign subsidiaries except for Ireland, Singapore, and Egypt where the United States (U.S.) dollar is used as the functional currency. We translate assets and liabilities of foreign operations, excluding Ireland, Singapore, and Egypt, to U.S. dollars at current rates of exchange and revenues and expenses are translated using weighted average rates. We include foreign currency translation adjustments in Stockholders’ equity as a component of Accumulated other comprehensive income. We maintain the accounting records for our subsidiaries in Ireland, Singapore, and Egypt in the U.S. dollar and accordingly no translation is necessary. We include foreign currency transaction gains and losses as a component of Other income (expense), net.

Use of Estimates

U.S. generally accepted accounting principles require management to make estimates and assumptions that affect the reported amount of assets, liabilities, and contingencies at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Such estimates include valuation of accounts receivable, goodwill, intangible assets, other long-lived assets, and assumptions used in the calculation of income taxes, among others. These estimates and assumptions are based on our best estimates and judgment. We evaluate our estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which we believe to be reasonable under the circumstances. We adjust such estimates and assumptions when facts and circumstances dictate. Illiquid credit markets, volatile equity markets, foreign currency fluctuations, and declines in customer spending have combined to increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ from these estimates. Changes in estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.

Cash Equivalents

Cash equivalents totaled $29,800 as of January 31, 2010 and $38,414 as of January 31, 2009 and included certificates of deposit and other highly liquid investments with original maturities of ninety days or less.

45

Investments

Long-term investments, included in Other assets on the accompanying Consolidated Balance Sheets, include investments with maturities in excess of one year from the balance sheet date, investments with indefinite lives, and equity securities. We determine the appropriate classification of our investments at the time of purchase. For investments in equity securities, we use the equity method of accounting when our investment gives us the ability to exercise significant influence over the operating and financial policies of the investee. Under the equity method, we currently record our share of earnings or losses in Other income (expense), net equal to our proportionate share of the earnings or losses of the investee. For debt securities and other equity securities with readily determinable fair values (marketable securities), we classify our investment as held-to-maturity when we have the positive intent and ability to hold the securities to maturity. We state held-to-maturity securities at cost, adjusted for amortization of premiums and discounts to maturity. Marketable securities not classified as held-to-maturity are classified as available-for-sale. We carry available-for-sale securities at fair value based on quoted market prices. We report unrealized gains and losses of available-for-sale securities net of tax in Stockholders’ equity as a component of Accumulated other comprehensive income. For investments in equity securities of private companies without a readily determinable fair value, and as to which we do not exercise significant influence over the investee, we record our investment under the cost method of accounting. Under the cost method of accounting, we carry the investment at historical cost and we periodically evaluate the fair value of the investment to determine if an other-than-temporary decline in value has occurred. For the year ended January 31, 2009, we recorded impairment losses for two long-term investments which had an other-than-temporary decline in value.

Term Receivables and Trade Accounts Receivable

We have long-term installment receivables that are attributable to multi-year, multi-element term license sales agreements. We include balances under term agreements that are due within one year in Trade accounts receivable, net and balances that are due more than one year from the balance sheet date in Term receivables, long-term. We discount the total product portion of the agreements to reflect the interest component of the transaction. We amortize the interest component of the transaction, using the effective interest method, to System and software revenues over the period in which payments are made and balances are outstanding. We determine the discount rate at the outset of the arrangement based upon prevailing rates of the customer. We reset the discount rate periodically considering changes in prevailing interest rates.

Trade accounts receivable include billed amounts of $110,839 as of January 31, 2010 and $133,719 as of January 31, 2009 and unbilled amounts of $178,911 as of January 31, 2010 and $139,133 as of January 31, 2009. Unbilled amounts included in Trade accounts receivable are for the portion of long-term installment agreements that are due within one year. Billings for term agreements typically occur 30 days prior to the contractual due date, in accordance with individual contract installment terms. Term receivables, long-term of $164,898 as of January 31, 2010 and $146,682 as of January 31, 2009 represent unbilled amounts which are scheduled to be collected beyond one year.

Valuation of Trade Accounts Receivable

We maintain allowances for doubtful accounts on trade accounts receivable and Term receivables, long-term for estimated losses resulting from the inability of our customers to make required payments. We regularly evaluate the collectibility of our trade accounts receivable based on a combination of factors. When we become aware of a specific customer’s inability to meet its financial obligations, such as in the case of bankruptcy or deterioration in the customer’s operating results, financial position, or credit rating, we record a specific reserve for bad debt to reduce the related receivable to the amount believed to be collectible. We also record unspecified reserves for bad debt for all other customers based on a variety of factors including length of time the receivables are past due, the financial health of the customers, the current business environment, and historical experience. Current economic conditions we have considered include forecasted spending in the semiconductor industry, consumer spending for electronics, integrated circuit research and development spending, and volatility in gross domestic product. If these factors change or circumstances related to specific customers change, we adjust the estimates of the recoverability of receivables resulting in either additional selling expense or a reduction in selling expense in the period such determination is made.

Concentrations of Credit Risk

We place our cash, cash equivalents, and short-term investments with major banks and financial institutions. Our investment policy limits our credit exposure to any one financial institution. We do not believe we are exposed to significant credit risk or market risk on our financial instruments.

46

Our concentrations of credit risk with respect to trade receivables are limited due to the large number of customers comprising our customer base and their dispersion across different businesses and geographic areas. However, the allowance for doubtful accounts, which is based on management’s best estimates, could be adjusted in the near term depending on actual experience. An adjustment could be material to our consolidated financial statements.

Fair Value of Financial Instruments

The carrying amounts of Cash equivalents, Short-term investments, Trade accounts receivable, net, term receivables, Short-term borrowings, Accounts payable, and Accrued liabilities approximate fair value because of the short-term nature of these instruments or because amounts have been appropriately discounted. We record foreign currency exchange contracts based on quoted market prices. We base the fair value of long-term notes payable on the quoted market price or rates available to us for instruments with similar terms and maturities. See further discussion in Note 5. “Fair Value Measurement.”

Property, Plant, and Equipment, Net

We state property, plant, and equipment at cost. We capitalize expenditures for additions to property, plant, and equipment. We expense maintenance and repairs which do not improve or extend the life of the respective asset as incurred. We compute depreciation on a straight-line basis over lives of forty years for buildings and twenty years for land improvements. We compute depreciation of computer equipment and furniture principally on a straight-line basis over the estimated useful lives of the assets, generally three to five years. We amortize leasehold improvements on a straight-line basis over the lesser of the term of the lease or estimated useful lives of the improvements, generally three to ten years.

Goodwill, Intangible Assets, and Long-Lived Assets

Goodwill represents the excess of the aggregate purchase price over the fair value of the tangible and other intangible assets acquired in our business combinations. Intangible assets, net primarily includes purchased technology, in-process research and development, trademarks, and customer relationships acquired in our business combinations. We operate as a single reporting unit for purposes of goodwill evaluation. We amortize intangible assets over their estimated lives.

We review long-lived assets, including intangible assets with definite lives, for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may not be recoverable. We assess the recoverability of our long-lived assets by determining whether the carrying values of the asset groups are greater than the forecasted undiscounted net cash flows of the related asset group. If we determine the assets are impaired, we write down the assets to their estimated fair value. We determine fair value based on forecasted undiscounted net cash flows or appraised values, depending upon the nature of the assets. In the event we determine our long-lived assets have been impaired, we would make an adjustment that would result in a charge for the write-down in the period that such determination was made. We determined that certain long-lived assets were impaired as of January 31, 2009. See further discussion in Note 4. “Impairment of Long-Lived Assets.”

Goodwill is not amortized, but is tested for impairment at least annually and as necessary if changes in facts and circumstances indicate that the fair value of our reporting unit may be less than the carrying amount. We completed our annual goodwill impairment test as of January 31, 2010, 2009, and 2008. As of January 31, 2010, 2009, and 2008, our annual impairment analysis of goodwill provided no indicators that a potential impairment existed for our reporting unit and accordingly no impairment charge was recognized during fiscal 2010, 2009, or 2008.

We amortize purchased technology over three to five years to System and software cost of revenues and other intangible asset costs over the same period to Operating expenses. For capitalized in-process research and development, upon completion of the in-process research and development projects, we will amortize in-process research and development to Cost of revenues over the life of the projects. Alternatively, if we abandon, the project, the in-process research and development costs will be expensed to Operating expense when such determination is made. Total purchased technology and other intangible asset amortization expenses were $23,196 for the year ended January 31, 2010, $23,516 for fiscal 2009, and $18,404 for fiscal 2008.

As of January 31, 2010, the carrying value of Goodwill was $458,313, net purchased technology and in-process research and development was $16,912, including accumulated amortization of $89,572, and net other intangible assets was $9,117, including accumulated amortization of $45,791.

47

As of January 31, 2009, the carrying value of Goodwill was $441,221, net purchased technology was $21,641, including accumulated amortization of $77,560, and net other intangible assets was $18,094, including accumulated amortization of $34,607.

We estimate the aggregate amortization expense related to purchased technology and other intangible assets will be as follows:

Fiscal years ending January 31,
2011	$	15,155
2012		7,577
2013		2,843
2014		454
Aggregate amortization expense		26,029

Income Taxes

We use the asset and liability method of accounting for income taxes. Under this method, we recognize deferred income taxes for the future tax consequences attributable to temporary differences between the financial statement carrying amounts and tax balances of existing assets and liabilities. We calculate deferred tax assets and liabilities using enacted tax rates and laws that will be in effect when we expect the differences to reverse and be applied to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are recognized for deductible temporary differences, net operating loss carryforwards, and credit carryforwards if it is more likely than not that the tax benefits will be realized. Deferred tax assets are not recorded to the extent they relate to tax deductions in excess of the stock-based compensation recorded under U.S. generally accepted accounting principles. Further, deferred tax assets are not recorded to the extent they are directly associated with uncertain tax positions. For deferred tax assets that are not more-likely-than-not-realizable, we have established a valuation allowance. In the event we determine that we would be able to realize our deferred tax assets in the future in excess of our net recorded amount, we would reverse the valuation allowance associated with such deferred tax assets in the period such determination was made. Also, if we were to determine that we would not be able to realize all or part of our net deferred tax assets in the future, we would charge an adjustment to increase the valuation allowance on such net deferred tax assets generally to expense in the period such determination was made.

Derivative Financial Instruments

We transact business in various foreign currencies and have established a foreign currency hedging program to hedge certain foreign currency forecasted transactions and exposures from existing assets and liabilities. Our derivative instruments consist of foreign currency forward and option contracts. We minimize counterparty credit risk by entering into derivative transactions with major financial institutions and, as such, we do not expect material losses as a result of default by our counterparties. We execute foreign currency transactions in exchange-traded or over-the-counter markets for which quoted prices exist. Contracts generally have maturities that do not exceed one year. We do not hold or issue derivative financial instruments for speculative or trading purposes.

We report the fair value of derivatives as a net asset or liability in the Consolidated Balance Sheet. The accounting for changes in the fair value of a derivative depends upon whether it has been designated in a hedging relationship and the type of hedging relationship. To qualify for designation in a hedging relationship, specific criteria must be met and the appropriate documentation maintained. Hedging relationships, if designated, are established pursuant to our risk management policy and are initially and regularly evaluated to determine whether they are expected to be, and have been, highly effective hedges. We discontinue hedge accounting prospectively when we determine that a derivative is not highly effective as a hedge and recognize future changes in the fair value of the derivative in earnings each period. We recognize changes in the fair value of derivatives not designated in a hedging relationship or derivatives that do not qualify for hedge accounting in earnings each period. For derivatives designated as a hedge of a forecasted transaction (cash flow hedge), we report the effective portion of the change in the fair value of the derivative in Stockholders’ equity as a component of Accumulated other comprehensive income and reclassify it to earnings in the period in which the forecasted transaction occurs. We recognize amounts excluded from the effectiveness calculation and any ineffective portion of the change in fair value of the derivative currently in earnings. We regularly evaluate forecasted transactions designated as the hedged item in a cash flow hedge to assess whether they continue to be probable of occurring. If the forecasted transaction is no longer probable of occurring, we recognize any gain or loss deferred in Accumulated other comprehensive income in earnings currently.

48

Revenue Recognition

We report revenue in two categories based upon how the revenue is generated: (i) system and software and (ii) service and support.

System and software revenues – We derive system and software revenues from the sale of licenses of software products, emulation hardware systems, and finance fee revenues from our long-term installment receivables resulting from product sales. We primarily license our products using two different license types:

1. Term licenses – We use this license type primarily for software sales. This license type provides the customer with the right to use a fixed list of software products for a specified time period, typically three years, with payments spread over the license term, and does not provide the customer with the right to use the products after the end of the term. Term license arrangements may allow the customer to share products between multiple locations and remix product usage from the fixed list of products at regular intervals during the license term. We generally recognize product revenue from term license arrangements upon product delivery and start of the license term. In a term license agreement where we provide the customer with rights to unspecified or unreleased future products, we recognize revenue ratably over the license term. Revenue from emulation hardware system sales is generally recognized upon delivery.

2. Perpetual licenses – We use this license type for software and emulation hardware system sales. This license type provides the customer with the right to use the product in perpetuity and typically does not provide for extended payment terms. We generally recognize product revenue from perpetual license arrangements upon product delivery assuming all other criteria for revenue recognition have been met.

We include finance fee revenues from the accretion on the discount of long-term installment receivables in System and software revenues. Finance fee revenues were $14,913 for the year ended January 31, 2010, $16,263 for fiscal 2009, and $16,732 for fiscal 2008.

Service and support revenues – We derive service and support revenues from software and hardware post-contract maintenance or support services and professional services, which include consulting, training, and other services. We recognize revenue ratably over the support services term. We record professional service revenue as the services are provided to the customer.

We apply the Financial Accounting Standards Board (FASB) guidance applicable to software revenue recognition to all software and hardware product revenue transactions where the software is not incidental. We determine whether product revenue recognition is appropriate based upon the evaluation of whether the following four criteria have been met:

1. Persuasive evidence of an arrangement exists – Generally, we use either a customer signed contract or qualified customer purchase order as evidence of an arrangement for both term and perpetual licenses. For professional service engagements, we generally use a signed professional services agreement and a statement of work to evidence an arrangement. Sales through our distributors are evidenced by an agreement governing the relationship, together with binding purchase orders from the distributor on a transaction-by-transaction basis.

2. Delivery has occurred – We generally deliver software and the corresponding access keys to customers electronically. Electronic delivery occurs when we provide the customer access to the software. We may also deliver the software on a compact disc. With respect to emulation hardware systems, we transfer title to the customer upon shipment. We offer non-essential installation services for emulation hardware system sales or the customer may elect to perform the installation without our assistance. Our software license and emulation hardware system agreements generally do not contain conditions for acceptance.

3. Fee is fixed or determinable – We assess whether a fee is fixed or determinable at the outset of the arrangement, primarily based on the payment terms associated with the transaction. We have established a history of collecting under the original contract with installment terms without providing concessions on payments, products, or services. Additionally, for installment contracts, we determine that the fee is fixed or determinable if the arrangement has a payment schedule that is within the term of the licenses and the payments are collected in equal or nearly equal installments, when evaluated on a cumulative basis. If the fee is not deemed to be fixed or determinable, we recognize revenue as payments become due and payable.

Significant judgment is involved in assessing whether a fee is fixed or determinable. We must also make these judgments when assessing whether a contract amendment to a term arrangement (primarily in the context of a license extension or renewal) constitutes a concession. Our experience has been that we are able to determine whether a fee is fixed or determinable for term licenses. If we no longer were to have a history of collecting under

49

the original contract without providing concessions on term licenses, revenue from term licenses would be required to be recognized when payments under the installment contract become due and payable. Such a change could have a material impact on our results of operations.

4. Collectibility is probable – To recognize revenue, we must judge collectibility of the arrangement fees on a customer-by-customer basis pursuant to our credit review process. We typically sell to customers with whom there is a history of successful collection. We evaluate the financial position and a customer’s ability to pay whenever an existing customer purchases new products, renews an existing arrangement, or requests an increase in credit terms. For certain industries for which our products are not considered core to the industry or the industry is generally considered troubled, we impose higher credit standards. If we determine that collectibility is not probable based upon our credit review process or the customer’s payment history, we recognize revenue as payments are received.

Multiple element arrangements – For multiple element arrangements, vendor-specific objective evidence of fair value (VSOE) must exist to allocate the total fee among all delivered and non-essential undelivered elements of the arrangement. If undelivered elements of the arrangement are essential to the functionality of the product, we defer revenue until the essential elements are delivered. If VSOE does not exist for one or more non-essential undelivered elements, we defer revenue until such evidence does exist for the undelivered elements, or until all elements are delivered, whichever is earlier. If VSOE of all non-essential undelivered elements exists but VSOE does not exist for one or more delivered elements, we recognize revenue using the residual method. Under the residual method, we defer revenue related to the undelivered elements based upon VSOE and we recognize the remaining portion of the arrangement fee as revenue for the delivered elements, assuming all other criteria for revenue recognition have been met. If we could no longer establish VSOE for non-essential undelivered elements of multiple element arrangements, we would defer revenue until all elements are delivered or VSOE is established for the undelivered elements, whichever is earlier.

We base our VSOE for certain product elements of an arrangement upon the pricing in comparable transactions when the element is sold separately. We primarily base our VSOE for term and perpetual support services upon customer renewal history where the services are sold separately. We also base VSOE for professional services and installation services for emulation hardware systems upon the price charged when the services are sold separately.

Software Development Costs

We capitalize software development costs beginning when a product’s technological feasibility has been established by either completion of a detail program design or completion of a working model of the product and ending when a product is available for general release to customers. The period between the achievement of technological feasibility and the general release of our products has historically been of short duration. As a result, such capitalizable software development costs were insignificant and have been charged to Research and development expense in the accompanying Consolidated Statements of Operations. We capitalized acquired technology costs of $468 during fiscal 2009. We did not capitalize any acquired technology costs during fiscal 2010 or fiscal 2008.

Leases

For lease agreements with escalation clauses, we record the total rent to be paid under the lease on a straight-line basis over the term of the lease, with the difference between the expense recognized and the cash paid recorded as a deferred rent liability included in Accrued liabilities, for amounts to be recognized within twelve months, and Other long-term liabilities, for amounts to be recognized after twelve months from the balance sheet date, in the Consolidated Balance Sheets.

Advertising Costs

We expense all advertising costs as incurred. Advertising expense was $3,668 for the year ended January 31, 2010, $4,447 for fiscal 2009, and $5,789 for fiscal 2008, and is included in Marketing and selling expense in the accompanying Consolidated Statements of Operations.

Special Charges

We record restructuring charges within Special charges in the Consolidated Statements of Operations in connection with our plans to better align our cost structure with projected operations in the future. Special charges primarily consist of costs incurred for employee terminations due to a reduction of personnel resources driven by modifications of business strategy or business emphasis. Special charges may also include expenses incurred related to potential acquisitions, excess facility costs, asset-related charges, post-acquisition rebalance costs and restructuring costs, including severance and benefits.

50

Net Income (Loss) Per Share

We compute basic net income (loss) per share using the weighted average number of common shares outstanding during the period. We compute diluted net income (loss) per share using the weighted average number of common shares and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares consist of common shares issuable upon exercise of employee stock options, purchase rights from employee stock purchase plans, and warrants using the treasury stock method and common shares issuable upon conversion of the convertible subordinated debentures, if dilutive. See additional discussion in Note 15. “Net Income (Loss) Per Share.”

Accounting for Stock-Based Compensation

We measure stock-based compensation cost at the grant date, based on the fair value of the award, and recognize the expense on a straight-line basis over the employee’s requisite service period. For options and stock awards that vest fully on any termination of service, there is no requisite service period and consequently we recognize the expense fully in the period in which the award is granted. We present the tax benefit from the exercise of stock options that exceed the tax benefit for those options previously recorded as a financing activity in the Consolidated Statements of Cash Flows.

We have elected to compute the timing of excess tax benefits from the exercise of stock options on the “with-and-without” approach. Under this approach, we will not record an excess tax benefit until such time as a cash tax benefit is recognized. Further, we will include the impact of these excess tax benefits in the calculation of indirect tax attributes, such as the research and development credit and the domestic manufacturing deduction. We will compute the pool of excess tax benefits available to offset any future shortfalls in the tax benefits actually realized on exercises of stock options as a single pool for employees and non-employees.

Other Comprehensive Income (Loss)

We record comprehensive income (loss) in accordance with the applicable FASB guidance, which defines comprehensive income (loss) as the change in equity during a period from transactions and other events and circumstances from nonowner sources, including net income (loss) as well as foreign currency translation adjustments, adjustments to the minimum pension liability, unrecognized actuarial losses not included in periodic benefit costs for a defined benefit plan in Japan, and unrealized gain (loss) on derivative contracts.

Transfer of Financial Assets

We finance certain software license agreements with customers through the sale, assignment, and transfer of the future payments under those agreements to financing institutions on a non-recourse basis. We retain no interest in the transferred receivable. We record such transfers as sales of the related accounts receivable when we are considered to have surrendered control of such receivables. The gain or loss on the sale of receivables is included in General and administration in Operating expenses in our Consolidated Statement of Operations. The gain or loss on the sale of receivables consists of two components: (i) the discount on sold receivables, which is the difference between the undiscounted balance of the receivables, and the net proceeds received from the financing institution and (ii) the unaccreted interest on the receivables sold. We impute interest on the receivables based on prevailing market rates and record this as a discount against the receivable.

51

We sold the following trade receivables to financing institutions on a non-recourse basis and recognized the following (gain) loss on the sale of those receivables:

Year ended January 31,	2010			2009			2008
Trade receivables, short-term	$	14,557		$	28,059		$	29,921
Term receivables, long-term		19,452			29,128			34,084
Total receivables sold		34,009			57,187			64,005
Net proceeds		31,838			54,200			59,817
Discount on sold receivables		2,171			2,987			4,188
Unaccreted interest on sold receivables		(1,549	)		(3,011	)		(4,520	)

The FASB issued guidance in September 2009 setting forth requirements that must be met for an entity to recognize revenue from the sale of a delivered item that is part of a multiple-element arrangement when other items have not been delivered. This guidance eliminates the requirement that all undelivered elements have VSOE or third-party evidence before an entity can recognize the portion of an overall arrangement fee that is attributable to items that have already been delivered. This guidance requires that, in the absence of VSOE or third-party evidence, a company estimate a selling price and that the relative selling prices be used to allocate revenue amongst the elements of a multi-element arrangement, eliminating the use of the residual method. This guidance is effective for fiscal years beginning on or after June 15, 2010, but may be adopted earlier as of the beginning of an interim or fiscal year. The FASB amended this guidance in September 2009 to exclude from its scope tangible products that contain both software and non-software components that function together to deliver a product’s essential functionality. The amended guidance applies to all hardware product revenue transactions. We will adopt this guidance prospectively as of the beginning of our fiscal year ending January 31, 2011 for multi-element arrangements involving our emulation hardware systems. We expect that the adoption of this guidance will have an impact on our consolidated financial statements. The nature and magnitude of the specific effects will depend on the arrangements we enter into with multiple deliverables after the effective date of February 1, 2010.

3. Change in Accounting

In May 2008, the FASB issued guidance requiring issuers of convertible debt instruments that may be settled in cash upon conversion (including partial cash settlement) to separately account for the implied liability and equity components of the convertible debt in a manner that reflects the entity’s nonconvertible debt borrowing rate when interest cost is recognized in subsequent periods.

We adopted this guidance during the first quarter of fiscal 2010 as it applies to our 6.25% Convertible Subordinated Debentures (6.25% Debentures) due 2026. Prior to the first quarter of fiscal 2010, we carried the liability of the 6.25% Debentures at its principal value and only the contractual interest expense was recognized in our Consolidated Statements of Operations. This guidance requires retrospective application to all prior periods for which the 6.25% Debentures were outstanding prior to the date of adoption.

Upon adoption of this guidance and effective as of the issuance date of the 6.25% Debentures, we recorded $23,976 of the principal amount to equity, representing a debt discount for the difference between our estimated nonconvertible debt borrowing rate of 8.60% at the time of issuance and the coupon rate of the 6.25% Debentures. This debt discount is amortized as interest expense over the expected term using the effective interest method. In addition, we allocated $764 of the issuance costs to the equity component of the 6.25% Debentures and the remaining $5,606 of the issuance costs to the liability component of the 6.25% Debentures. The issuance costs were allocated pro rata based on their initial carrying amounts.

The impact of these adjustments to Interest expense, Income (loss) before income tax, Net income (loss), and Basic and diluted net income (loss) per share for the years ended January 31, 2009 and 2008 represents the amortization of the debt discount and adjustment to the previously recorded amortization of the issuance costs. The adjustments to the Consolidated Balance Sheet as of January 31, 2009 are to:

• Other assets and Prepaid expenses and other for the impact of the allocation of a portion of the issuance costs to equity;

• Notes payable for the unamortized debt discount on the 6.25% Debentures;

52

• Common stock for the recognition of the equity component of the 6.25% Debentures, net of a portion of the equity component that was retired upon repurchase of a portion of the 6.25% Debentures; and

• Accumulated deficit for the cumulative debt discount amortization, revised issuance cost amortization, and revised loss on the retirement of a portion of the debt recognized in interest expense from the issuance date of the 6.25% Debentures through January 31, 2009.

The effect of the adoption of the new guidance on the Consolidated Statements of Operations for the years ended January 31, 2009 and 2008 is as follows:

The adoption of the new guidance on the Consolidated Statement of Cash Flows for the years ended January 31, 2009 and 2008 had no effect on cash provided by operations, cash used in investing activities, or cash used in financing activities.

4. Impairment of Long-Lived Assets

At January 31, 2009, we completed a review of our long-lived assets for impairment due to the adverse market conditions and declines in our market capitalization. We assessed the recoverability of our long-lived assets by determining whether their carrying values were greater than the forecasted undiscounted net cash flows of the related assets. We determined the assets were impaired and wrote down the assets to their estimated fair value. We determined fair value based on forecasted undiscounted net cash flows or appraised values, depending upon the nature of the assets. For purposes of this evaluation, long-lived assets were grouped with other assets and liabilities at the lowest level for which identifiable cash flows were largely independent of the cash flows of other assets and liabilities. We subdivided long-lived assets into six separate asset groups for impairment testing. The long-lived assets of each group consisted primarily of purchased technology, other intangibles, and property, plant, and equipment. Based on this evaluation, it was determined that one of our asset groups was impaired.

54

We recorded an impairment loss of $4,553 during fiscal 2009 for the difference between the carrying value and the fair value of the long-lived assets of this asset group. We used an income approach and forecasted undiscounted net cash flows to determine the fair value of the assets. The impairment was recorded in Operating expenses in our Consolidated Statement of Operations for fiscal 2009. The impaired assets continue to be used in our operations.

5. Fair Value Measurement

We measure derivative instruments at fair value on a quarterly basis. The FASB’s authoritative guidance established a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources. Unobservable inputs reflect our market assumptions. The fair value hierarchy consists of the following three levels:

• Level 1 – Quoted prices for identical instruments in active markets;

• Level 2 – Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations whose significant inputs are observable; and

• Level 3 – One or more significant inputs to the valuation model are unobservable.

The following table presents information about financial assets and liabilities required to be carried at fair value on a recurring basis as of January 31, 2010:

	Fair Value			Level 1		Level 2			Level 3
Foreign currency exchange contracts	$	(4,619	)	$	–	$	(4,619	)	$	–
Contingent consideration		(1,822	)		–		–			(1,822	)
Total	$	(6,441	)	$	–	$	(4,619	)	$	(1,822	)

The following table presents information about financial assets and liabilities required to be carried at fair value on a recurring basis as of January 31, 2009:

	Fair Value			Level 1		Level 2			Level 3
Foreign currency exchange contracts	$	(3,138	)	$	–	$	(3,138	)	$	–

We use an income approach to determine the fair value of our foreign currency exchange contracts. For foreign currency exchange contracts designated as cash flow hedges, which are linked to a specific transaction, we report the net gains and losses in Accumulated other comprehensive income in Stockholders’ equity until the forecasted transaction occurs or the hedge is no longer effective. Once the forecasted transaction occurs or the hedge is no longer effective, we reclassify the gains or losses attributable to the foreign currency exchange contracts to our Consolidated Statement of Operations. For foreign currency exchange contracts entered into to offset the variability in exchange rates on certain short-term monetary assets and liabilities, we recognize changes in fair value currently in Other income (expense), net, in our Consolidated Statement of Operations. See further discussion in Note 8. “Derivative Instruments and Hedging Activities.”

In connection with a fiscal 2010 acquisition, payment of a portion of the purchase price is contingent upon the acquired business’ achievement of certain revenue goals. We have estimated the fair value of this contingent consideration as the present value of the expected contingent payments over the term of the arrangement discounted at a rate of 16% and recorded a liability of $1,822 as of January 31, 2010.

The following table summarizes Level 3 activity:

Balance as of January 31, 2009	$	–
Contingent consideration		1,770
Interest accretion		52
Balance as of January 31, 2010	$	1,822

55

The carrying amounts of cash equivalents, Short-term investments, Trade accounts receivable, net, term receivables, Accounts payable, and accrued liabilities approximate fair value because of the short-term nature of these instruments or because amounts have been appropriately discounted. We record foreign currency exchange contracts based on quoted market prices for similar instruments. The fair value of Notes payable was $192,321 as of January 31, 2010 and $134,549 as of January 31, 2009 compared to the carrying value of $188,347 as of January 31, 2010 and $188,170 as of January 31, 2009. We based the fair value of Notes payable on the quoted market price or rates available to us for instruments with similar terms and maturities. Of the total carrying value of Notes payable, $32,272 was classified as current on our Consolidated Balance Sheet as of January 31, 2010. The carrying amount of the remaining balance of Short-term borrowings of $37,874 as of January 31, 2010 and $36,998 as of January 31, 2009 approximates fair value because of the short-term nature of the instruments.

6. Business Combinations

During the years ended January 31, 2010, 2009, and 2008 we made a number of acquisitions. For each acquisition, the excess of the fair value of the consideration transferred over the fair value of the net tangible assets acquired and net tangible liabilities assumed was allocated to various identifiable intangible assets and goodwill. Identifiable intangible assets typically consist of purchased technology and customer-related intangibles, which are amortized to expense over their useful lives. Goodwill, representing the excess of the purchase consideration over the fair value of net tangible and identifiable intangible assets, is not amortized.

Acquisitions during the year ended January 31, 2010

Acquisition	Total Consideration Transferred		Net Tangible Assets Acquired		Identifiable Intangible Assets Acquired		Deferred Tax Liability			Goodwill
LogicVision, Inc.	$	15,352	$	1,151	$	7,470	$	–		$	6,731
Other		9,310		190		2,490		(222	)		6,852
	$	24,662	$	1,341	$	9,960	$	(222	)	$	13,583

On August 18, 2009, we acquired all of the outstanding common shares of LogicVision, Inc. (LogicVision), a test and yield learning company in the semiconductor design-for-test sector. The acquisition was an investment aimed at extending our product offerings within the EDA industry. Under the terms of the purchase agreement, LogicVision shareholders received 0.2006 of a share of our common stock for each LogicVision common share. Accordingly, we issued 1,903 shares of our common stock to the former common shareholders of LogicVision, resulting in consideration transferred for the common stock issued of $14,289, at our closing price on August 18, 2009 of $7.51 per share. The purchase agreement also required that we exchange our stock options for LogicVision’s outstanding stock options resulting in additional consideration of $1,063, representing the fair value of stock options issued that is attributable to the pre-combination service period. The identified intangible assets acquired consisted of purchased technology of $5,260 and other intangibles of $2,210. The goodwill created by the transaction is not deductible for tax purposes. Key factors that make up the goodwill created by the transaction include expected synergies from the combination of operations, future technologies, and the knowledge and experience of the acquired workforce. We included the results of the LogicVision operations in our consolidated financial statements from the date of acquisition forward.

Other acquisitions for the year ended January 31, 2010 consisted of three privately-held companies, which were not material individually or in the aggregate.

Acquisitions during the year ended January 31, 2009

Acquisition	Total Consideration Transferred		Net Tangible Assets Acquired / (Liabilities Assumed)			Identifiable Intangible Assets Acquired		Deferred Tax Liability			In-Process Research & Development		Goodwill
Flomerics Group, PLC	$	58,588	$	13,549		$	25,870	$	(7,281	)	$	6,790	$	19,660
Other		5,687		(567	)		1,970		–			1,300		2,984
	$	64,275	$	12,982		$	27,840	$	(7,281	)	$	8,090	$	22,644

In May 2008, our Board of Directors announced a cash offer to acquire all of the issued or to be issued ordinary shares of Flomerics Group, PLC (Flomerics), a publicly traded company headquartered in Surrey, United Kingdom. Flomerics was a market leader in the computer simulation of mechanical engineering design processes including heat transfer and fluid flow simulation. On July 9, 2008, we obtained greater than 50% of the then outstanding ordinary shares of Flomerics and we began including Flomerics in our results of operations. As of January 31, 2009, we had acquired all of the outstanding or to be outstanding, ordinary shares of Flomerics. The identifiable intangible assets of Flomerics consist of purchased technology of $17,870 and other identified assets of $8,000. The goodwill created by the transaction is not deductible for tax purposes.

Other acquisitions for the year ended January 31, 2009 consisted of a privately-held company we acquired for cash, which was not individually material.

Acquisitions during the year ended January 31, 2008

Acquisition	Total Consideration Transferred		Net Tangible Assets Acquired		Identifiable Intangible Assets Acquired		Deferred Tax Asset		In-Process Research & Development		Goodwill
Sierra Design Automation, Inc.	$	84,818	$	6,385	$	26,600	$	1,801	$	4,100	$	45,932
Other		838		4		220		–		–		614
	$	85,656	$	6,389	$	26,820	$	1,801	$	4,100	$	46,546

On June 8, 2007, we acquired 100% of the common stock of Sierra Design Automation, Inc. (Sierra), a privately held company based in Santa Clara, California, which is a provider of high-performance place and route software solutions. Upon completion of the merger transaction, the outstanding shares of Sierra were converted into the right to receive consideration from us totaling $90,000, of which $45,000 was payable in cash and $45,000 was payable in the form of 3,097 shares of our common stock valued as provided in the merger agreement at $14.53 per share which was the average closing price reported by The NASDAQ Global Select Market for the 10 trading-day period ending three days before the closing. Cash of $3,717 and 256 shares of our common stock with a value of $3,721 were withheld pro rata from the former Sierra shareholders and deposited in an indemnity escrow account. These amounts were released in October 2008. The indemnity escrow account also included $783 of cash and 56 shares of our common stock valued at $810 withheld from Sierra’s two founders; these amounts plus an additional 166 shares of our common stock valued at $2,407 withheld from the founders were subject to forfeiture if their employment with us had terminated by them without good reason or by us for cause before June 8, 2009. The two founders completed their employment terms and no forfeitures were taken.

In accounting for the Sierra transaction, we were required to value the shares of our common stock issued in the transaction at $13.85 per share which was the average closing price reported by The NASDAQ Global Select Market for the five day period beginning with the two day period preceding the measurement date through the two days succeeding the measurement date. In addition, the cash and common stock withheld from the two Sierra founders of $3,797, which was subject to a continued employment requirement, was considered compensation expense and was recognized over the service period and was not included in the acquisition cost. The common stock withheld from the two Sierra founders was valued at $13.61 per share. The identified intangible assets acquired consisted of purchased technology of $9,400 and other intangibles of $17,200. We are amortizing the technology to Cost of revenues and the other identified intangible assets to Operating expenses over three years. We included the results of the Sierra operations in our consolidated financial statements from the date of acquisition forward.

57

Other acquisitions for the year ended January 31, 2008 consisted of a privately-held company we acquired for cash, which was not individually material.

The separate results of operations for the acquisitions during the years ended January 31, 2010, 2009, and 2008 were not material, individually or in the aggregate, compared to our overall results of operations and accordingly pro-forma financial statements of the combined entities have been omitted.

The value assigned to in-process research and development for the charges incurred related to business acquisitions in the years ended January 31, 2009 and 2008 related to research projects for which technological feasibility had not been established. The value was determined by estimating the net cash flows from the sale of products resulting from the completion of such projects and discounting the net cash flows back to their present value. The rate used to discount the net cash flows was based on the weighted average cost of capital. Other factors considered were the inherent uncertainties in future revenue estimates from technology investments including the uncertainty surrounding the successful development of the acquired in-process technology, the useful life of the technology, the profitability levels of the technology, and the stage of completion of the technology. The stage of completion of the products at the date of the acquisition were estimated based on research and development costs that had been expended as of the date of acquisition as compared to total research and development costs expected at completion. The percentages derived from this calculation were then applied to the net present value of future cash flows to determine the in-process charge. The nature of the efforts to develop the in-process technology into commercially viable products principally related to the completion of all planning, designing, prototyping, verification, and testing activities that are necessary to establish that the product can be produced to meet its design specification, including function, features, and technical performance requirements. The estimated net cash flows from these products were based on estimates of related revenues, cost of sales, research and development costs, selling, general and administration costs, and income taxes. These estimates are subject to change, given the uncertainties of the development process, and no assurance can be given that deviations from these estimates will not occur or that we will realize any anticipated benefits of the acquisition. The risks associated with acquired research and development are considered high and no assurance can be made that these products will generate any benefit or meet market expectations.

7. Property, Plant, and Equipment, Net

A summary of property, plant, and equipment, net follows:

As of January 31,	2010			2009
Computer equipment and furniture	$	247,211		$	226,975
Buildings and building equipment		62,363			48,939
Land and improvements		20,782			12,445
Leasehold improvements		43,708			41,105
		374,064			329,464
Less accumulated depreciation and amortization		(252,269	)		(228,473	)
Property, plant, and equipment, net	$	121,795		$	100,991

In January 2010, we purchased three buildings in Fremont, California. We capitalized $21,152 in acquisition costs which is included in Buildings and building equipment and Land and improvements. We plan to relocate all of our San Jose research and development, sales, and administrative operations to Fremont at the termination of our existing San Jose leases in the third quarter of fiscal 2011. We will begin to depreciate the facilities once we begin to occupy them.

8. Derivative Instruments and Hedging Activities

We are exposed to fluctuations in foreign currency exchange rates. To manage the volatility, we aggregate exposures on a consolidated basis to take advantage of natural offsets. The primary exposures that do not currently have natural offsets are the Japanese yen, where we are in a long position, and the euro and the British pound, where we are in a short position. Most large European revenue contracts are denominated and paid to us in the U.S. dollar while our European expenses, including substantial research and development operations, are paid in local currencies causing a short position in the euro and the British pound. In addition, we experience greater inflows than outflows of Japanese yen as almost all Japanese-based customers contract and pay us in Japanese yen. While these exposures are aggregated on a consolidated basis to take advantage of natural offsets, substantial exposure remains.

58

To partially offset the net exposures in the euro, British pound, and the Japanese yen, we enter into foreign currency exchange contracts of a year or less which are designated as cash flow hedges. Any gain or loss on Japanese yen contracts is classified as product revenue when the hedged transaction occurs while any gain or loss on euro and British pound contracts is classified as operating expense when the hedged transaction occurs. During the year ended January 31, 2010, we entered into 15 new foreign currency option contracts, with a total gross notional value of $81,492 and 166 new foreign currency forward contracts, with a gross notional value of $732,519.

We formally document all relationships between foreign currency exchange contracts and hedged items as well as our risk management objectives and strategies for undertaking various hedge transactions. All hedges designated as cash flow hedges are linked to forecasted transactions and we assess, both at inception of the hedge and on an ongoing basis, the effectiveness of the foreign currency exchange contracts in offsetting changes in the cash flows of the hedged items. We report the effective portions of the net gains or losses on foreign currency exchange contracts as a component of Accumulated other comprehensive income in Stockholders’ equity. Accumulated other comprehensive income associated with hedges of forecasted transactions is reclassified to the Consolidated Statement of Operations in the same period as the forecasted transaction occurs. We discontinue hedge accounting prospectively when we determine that a foreign currency exchange contract is not highly effective as a hedge. To the extent a forecasted transaction is no longer deemed probable of occurring, we prospectively discontinue hedge accounting treatment and we reclassify deferred amounts to Other income (expense), net in the Consolidated Statement of Operations. We noted no such instance during the years ended January 31, 2010, 2009, or 2008.

The fair values and balance sheet presentation of our derivative instruments as of January 31, 2010 are summarized as follows:

As of January 31, 2010	Location	Asset Derivatives		Liability Derivatives
Derivatives designated as hedging instruments
Cash flow forwards	Accrued liabilities	$	91	$	(1,867	)
Derivatives not designated as hedging instruments
Non-designated forwards	Accrued liabilities		159		(3,002	)
Total derivatives		$	250	$	(4,869	)

We had foreign currency exchange contracts outstanding with a gross notional value of $182,572 as of January 31, 2010. Notional amounts do not quantify risk or represent our assets or liabilities but are used in the calculation of cash settlements under the contracts.

By using derivative instruments, we subject ourselves to credit risk. If a counterparty fails to fulfill its performance obligations under a derivative contract, our credit risk will equal the fair value of the derivative instrument. Generally when the fair value of our derivative contracts is in a net asset position, the counterparty owes us, thus creating a receivable risk. We minimize counterparty credit risk by entering into derivative transactions with major financial institutions and, as such, we do not expect material losses as a result of default by our counterparties.

The pre-tax effect of derivative instruments in cash flow hedging relationships on income and other comprehensive income (OCI) for the year ended January 31, 2010 is as follows:

Derivatives Designated as Hedging Instruments	Gain Recognized in OCI on Derivatives (Effective Portion)		Gain (Loss) Reclassified from Accumulated OCI into Income (Effective Portion)				Gain (Loss) Recognized in Income on Derivatives (Ineffective Portion and Amount Excluded from Effectiveness Testing)
	Amount		Location	Amount			Location	Amount
Cash flow forwards	$	3,641	Revenues	$	(2,350	)	Other income (expense), net	$	180
			Operating expenses		2,450
Cash flow options		13	Revenues		(419	)	Other income (expense), net		(5	)
			Operating expenses		(1,031	)
Total	$	3,654		$	(1,350	)		$	175

Included in the gain on cash flow forwards of $180 recognized in Other income (expense), net was a gain of $179 related to the time value exclusion of foreign currency forward contracts from our assessment of hedge effectiveness.

59

The hedge balance in Accumulated other comprehensive income as of January 31, 2010 of $1,587, after tax effect, represents a net unrealized loss on foreign currency exchange contracts related to hedges of forecasted revenues and expenses expected to occur within the next twelve months. We will transfer these amounts to the Consolidated Statement of Operations upon recognition of the related revenue and recording of the respective expenses. We expect substantially all of the hedge balance in Accumulated other comprehensive income to be reclassified to the Consolidated Statement of Operations within the next twelve months.

We enter into foreign currency exchange contracts to offset the earnings impact relating to the variability in exchange rates on certain short-term monetary assets and liabilities denominated in non-functional currencies. We do not designate these foreign currency contracts as hedges. The effect of derivative instruments not designated as hedging instruments on income for the year ended January 31, 2010 is as follows:

Derivatives Not Designated as Hedging Instruments	Gain Recognized in Income on Derivatives
	Location	Amount
Non-designated forwards	Other income (expense), net	$	5,924

9. Short-Term Borrowings

Short-term borrowings consisted of the following:

As of January 31,	2010		2009
Senior revolving credit facility	$	20,000	$	20,000

Short-term borrowings	$	37,874	$	36,998

In June 2005, we entered into a syndicated, senior, unsecured, four-year revolving credit facility. In April 2008, we extended this revolving credit facility by two years until June 1, 2011. In May 2008, we increased the maximum borrowing capacity from $120,000 to $140,000 and retained an option to increase it by an additional $10,000 in the future. In March 2009, we amended the revolving credit facility to reduce the minimum tangible net worth calculated as of January 31, 2009, which is used as the starting point for future calculations, by $15,000, and to make certain other changes reflected in the discussion below. Under this revolving credit facility, we have the option to pay interest based on: (i) London Interbank Offered Rate (LIBOR) with varying maturities which are commensurate with the borrowing period we select, plus a spread of between 1.0% and 1.6%, or (ii) a base rate plus a spread of between 0.0% and 0.6%, based on a pricing grid tied to a financial covenant. The base rate is defined as the higher of: (i) the federal funds rate, as defined, plus 0.5%, (ii) the prime rate of the lead bank, or (iii) one-month LIBOR plus 1.0%. As a result of these interest rate options, our interest expense associated with borrowings under this revolving credit facility will vary with market interest rates. In addition, commitment fees are payable on the unused portion of the revolving credit facility at rates between 0.25% and 0.35% based on a pricing grid tied to a financial covenant. We paid commitment fees of $386 for the year ended January 31, 2010, $327 for fiscal 2009, and $304 for fiscal 2008. This revolving credit facility contains certain financial and other covenants, including the following:

• Our adjusted quick ratio (ratio of the sum of cash and cash equivalents, short-term investments, and net current receivable to total current liabilities) shall not be less than 0.85;

• Our tangible net worth (stockholders’ equity less goodwill and other intangible assets) must exceed the calculated required tangible net worth as defined in the credit agreement, which establishes a fixed level of required tangible net worth. Each quarter the required level increases by 70% of any positive net income in the quarter (but in the aggregate no more than 70% of positive net income for any full fiscal year), 100% of the amortization of intangible assets in the quarter, and 100% of certain stock issuance proceeds. The required level also decreases each quarter by certain amounts of acquired intangible assets;

• Our leverage ratio (ratio of total liabilities less subordinated debt to the sum of subordinated debt and tangible net worth) shall not be greater than 2.20;

• Our senior leverage ratio (ratio of total debt less subordinated debt to the sum of subordinated debt and tangible net worth) shall be less than 0.90; and

60

• Our minimum cash and accounts receivable ratio (ratio of the sum of cash and cash equivalents, short-term investments, and 47.5% of net current accounts receivable, to outstanding credit agreement borrowings) shall not be less than 1.25.

The revolving credit facility prevents us from paying dividends.

We were in compliance with all financial covenants as of January 31, 2010. If we were to fail to comply with the financial covenants and did not obtain a waiver from our lenders, we would be in default under the revolving credit facility and our lenders could terminate the facility and demand immediate repayment of all outstanding loans under the revolving credit facility.

We borrowed $20,000 against the revolving credit facility and repaid $20,000 during fiscal 2010. We borrowed $30,000 against the revolving credit facility and repaid $10,000 during fiscal 2009. The interest rate was 3.25% as of January 31, 2010 and 2009.

Short-term borrowings include amounts collected from customers on accounts receivable previously sold on a non-recourse basis to financial institutions. These amounts are remitted to the financial institutions in the following quarter.

We generally have other short-term borrowings, including multi-currency lines of credit, capital leases, and other borrowings. Interest rates are generally based on the applicable country’s prime lending rate, depending on the currency borrowed.

10. Notes Payable

Notes payable consisted of the following:

As of January 31,	2010			2009
				As adjusted (Note 3)
6.25% Debentures due 2026	$	154,832		$	152,068
Floating Rate Debentures due 2023		32,272			36,102
Other		1,243			–
Notes payable		188,347			188,170
Floating Rate Debentures due 2023, current portion		(32,272	)		–
Notes payable, long-term	$	156,075		$	188,170

6.25% Debentures due 2026: In March 2006, we issued $200,000 of 6.25% Debentures in a private offering pursuant to SEC Rule 144A under the Securities Act of 1933. Interest on the 6.25% Debentures is payable semi-annually in March and September. The 6.25% Debentures are convertible, under certain circumstances, into our common stock at a conversion price of $17.968 per share for a total of 9,183 shares as of January 31, 2010. These circumstances generally include:

• The market price of our common stock exceeding 120% of the conversion price;

• The market price of the 6.25% Debentures declining to less than 98% of the value of the common stock into which the 6.25% Debentures are convertible;

• A call for the redemption of the 6.25% Debentures;

• Specified distributions to holders of our common stock;

• If a fundamental change, such as a change of control, occurs; or

• During the ten trading days prior to, but not on, the maturity date.

Upon conversion, in lieu of shares of our common stock, for each $1 principal amount of the 6.25% Debentures a holder will receive an amount of cash equal to the lesser of: (i) $1 or (ii) the conversion value of the number of shares of our common stock equal to the conversion rate. If such conversion value exceeds $1, we will also deliver, at our election, cash or common stock, or a combination of cash and common stock with a value equal to the excess. If a holder elects to convert their 6.25% Debentures in connection with a fundamental change in the company that occurs prior to March 6, 2011, the holder will also be entitled to receive a make whole premium upon conversion in some circumstances. The 6.25% Debentures rank pari passu with the Floating Rate Convertible Subordinated Debentures (Floating Rate Debentures) due 2023. We may redeem some or all of the 6.25% Debentures for cash on or after March 6, 2011. The holders, at their option, may redeem some or all of the 6.25% Debentures for cash on March 1, 2013, 2016, or 2021. During the years ended January 31, 2010 and 2009, we did not repurchase any 6.25% Debentures and the principal amount of $165,000 remains outstanding.

61

During the year ended January 31, 2008, we purchased on the open market and retired 6.25% Debentures with a principal balance of $35,000 for a total purchase price of $34,687. In connection with these purchases, we incurred a before tax net loss on the early extinguishment of debt of $506, which consisted of the write-off of $819 of unamortized debt issuance costs partially offset by discounts of $313 on repurchases.

During the first quarter of fiscal 2010, we adopted the FASB’s guidance which specifies that issuers of convertible debt that may be settled in cash upon conversion (including partial cash settlement) separately account for the implied liability and equity components of the convertible debt in a manner that reflects the issuer’s nonconvertible debt borrowing rate when interest cost is recognized in subsequent periods. This guidance applies to the 6.25% Debentures and requires retrospective application to all periods. The impact of the adoption of this guidance is further described in Note 3. “Change in Accounting.”

The principal amount, unamortized debt discount, and net carrying amount of the liability component as well as the carrying amount of the equity component of the 6.25% Debentures are as follows:

As of January 31,	2010			2009
Principal amount	$	165,000		$	165,000
Unamortized debt discount		(10,168	)		(12,932	)
Net carrying amount of the liability component	$	154,832		$	152,068
Equity component	$	21,766		$	21,766

The remaining unamortized debt discount will be amortized to interest expense using the effective interest method through March 2013.

We recognized the following amounts in Interest expense in the Consolidated Statements of Operations related to the 6.25% Debentures:

Year ended January 31	2010		2009		2008
Interest expense at the contractual interest rate	$	10,312	$	10,312	$	12,424
Amortization of debt discount		2,764		2,540		2,802

The effective interest rate on the 6.25% Debentures was 8.60% for the years ended January 31, 2010, 2009, and 2008.

Floating Rate Debentures due 2023: In August 2003, we issued $110,000 of Floating Rate Debentures in a private offering pursuant to SEC Rule 144A under the Securities Act of 1933. Interest on the Floating Rate Debentures is payable quarterly in February, May, August, and November at a variable interest rate equal to 3-month LIBOR plus 1.65%. The effective interest rate was 2.44% for the year ended January 31, 2010 and 4.54% for fiscal 2009. The Floating Rate Debentures are convertible, under certain circumstances, into our common stock at a conversion price of $23.40 per share, for a total of 1,379 shares as of January 31, 2010. These circumstances generally include:

• The market price of our common stock exceeding 120% of the conversion price;

• The market price of the Floating Rate Debentures declining to less than 98% of the value of the common stock into which the Floating Rate Debentures are convertible; or

• A call for redemption of the Floating Rate Debentures or certain other corporate transactions.

The conversion price may also be adjusted based on certain future transactions, such as stock splits or stock dividends. Effective August 2009, we may redeem some or all of the Floating Rate Debentures for cash at 100.81% of the face amount, with the premium reducing to 0% on August 6, 2010. The holders, at their option, may redeem some or all of the Floating Rate Debentures for cash on August 6, 2010, 2013, or 2018. We have reclassified the entire $32,272 of Floating Rate Debentures to short-term in our Consolidated Balance Sheet as of January 31, 2010 as holders, at their option, may redeem some or all of the Floating Rate Debentures for cash on August 6, 2010.

During the year ended January 31, 2010, we purchased on the open market and retired Floating Rate Debentures with a principal balance of $3,830 for a total purchase price of $3,450. In connection with these purchases, during the year ended January 31, 2010, we incurred a before tax net gain on the early extinguishment of debt of $354, which included a $380 discount on the repurchased Floating Rate Debentures and a write-off of $26 for a portion of unamortized deferred debt issuance costs.

62

During the year ended January 31, 2009, we did not repurchase any Floating Rate Debentures.

During the year ended January 31, 2008, we purchased on the open market and retired Floating Rate Debentures with a principal balance of $13,748 for a total purchase price of $14,083. In connection with these purchases, we incurred a before tax net loss on the early extinguishment of debt of $558, which consisted of the write-off of $223 of unamortized debt issuance costs and premiums of $335 on the repurchases of Floating Rate Debentures.

Other Notes Payable: In November 2009, we issued a subordinated note payable as part of a business combination with a principal balance of $1,234. The note bears interest at a rate of 3.875% and is due in full along with all accrued interest on November 17, 2012.

Deferred tax liabilities		(15,873	)		(11,649	)
Net deferred tax assets	$	18,938		$	33,008

As of January 31, 2010, for federal income tax purposes, we had net operating loss carryforwards of approximately $167,654, foreign tax credits of $3,480, research and experimentation credit carryforwards of $37,408, alternative minimum tax credits of $2,683, and childcare credits of $1,063. For state income tax purposes, we had net operating loss carryforwards totaling $173,707 from multiple jurisdictions, and research and experimentation and other miscellaneous state credits of $7,348.

Portions of our loss carryforwards, inherited through various acquisitions, are subject to annual limitations due to the change in ownership provisions of the Internal Revenue Code. If we do not use the carryforwards to reduce U.S. taxable income in future periods, portions of the net operating loss carryforwards will expire in fiscal years ending 2019 through 2030. The foreign tax credits will expire in fiscal years ending 2015 through 2020, research and experimentation credit carryforwards will expire between fiscal years ending 2011 through 2030, and childcare credits will expire between fiscal years ending 2023 and 2030. The alternative minimum tax credits do not expire. As of January 31, 2010, we have net operating losses in multiple foreign jurisdictions of $13,572. In general, we can carry forward the net operating losses for these foreign jurisdictions indefinitely.

Net operating loss carryforwards created by excess tax benefits from the exercise of stock options are not recorded as deferred tax assets. To the extent such net operating loss carryforwards are utilized, we will increase Stockholders’ equity. For presentation purposes, we have elected to exclude the historic deferred tax assets related to excess tax benefits from stock option exercises. Our deferred tax assets related to net operating losses and tax credit carryforwards have been accordingly reduced by $32,151 as of January 31, 2010 and $23,788 as of January 31, 2009. We had a total valuation allowance of $110,578 as of January 31, 2010 and $76,743 as of January 31, 2009. The increase in the valuation allowance largely resulted from an increase in net operating loss carryforwards in the U.S., the timing of the deduction on the accrued expenses, and the movement of the reserves in our tax position. We have determined the amount of the valuation allowance based on our estimates of taxable income by jurisdiction in which we operate over the periods in which the related deferred tax assets will be recoverable. We determined it is more likely than not that our U.S. entities will not generate sufficient taxable income and foreign source income to fully utilize foreign tax credit carryforwards, research and experimentation credit carryforwards, and net operating loss carryforwards before expiration. Accordingly, we recorded a valuation allowance against those deferred tax assets for which realization does not meet the more-likely-than-not standard. Similarly, there is a valuation allowance on the state deferred tax assets due to the same uncertainties regarding future taxable U.S. income. We determine valuation allowances related to certain foreign deferred tax assets based on historical losses as well as future expectations in certain jurisdictions.

We have not provided for income tax on the undistributed earnings of our foreign subsidiaries to the extent they are considered permanently re-invested outside the US. As of January 31, 2010, the cumulative amount of earnings upon which U.S. income taxes have not been provided for is approximately $303,612. Upon repatriation,

65

some of these earnings may be sheltered by U.S. loss carryforwards or the carryforward of foreign tax credits, which may reduce the federal tax liability associated with any future foreign dividend. To the extent that the earnings of our foreign subsidiaries are not treated as permanently reinvested, which include earnings of certain countries, we have considered the impact in our tax provision. Determination of the amount of unrecognized deferred U.S. income tax liability is not practicable; however, the potential foreign tax credit associated with the deferred income would be available to reduce the resulting U.S. tax liabilities.

We are subject to income taxes in the U.S. and in numerous foreign jurisdictions. In the ordinary course of business there are many transactions and calculations where the ultimate tax determination is uncertain. The statute of limitations for adjustments to our historic tax obligations will vary from jurisdiction to jurisdiction. In some cases it may be extended or be unlimited. Furthermore, net operating loss and tax credit carryforwards may be subject to adjustment after the expiration of the statute of limitations of the year such net operating losses and tax credits originated. Our larger jurisdictions generally provide for a statute of limitations from three to five years. The tax years for U.S. federal income tax purposes that remain open are fiscal years 2006 and forward. We are currently under examination in various jurisdictions. The examinations are in different stages and timing of their resolution is difficult to predict. In March 2007, the Internal Revenue Service (IRS) issued a Revenue Agent’s Report for fiscal 2002 through 2004 in which adjustments were asserted totaling $146,600 of additional taxable income. The adjustments primarily concern transfer-pricing arrangements related to intellectual property rights acquired in acquisitions that were transferred to a foreign subsidiary. During fiscal year 2010, we reached a settlement with the IRS, which was consistent with our expectations and addressed within the company’s reserve position. Further, due to the company’s available losses that could be applied, the settlement did not result in any significant cash outlay. The statute of limitations remains open for years on or after 2004 in Japan and 2005 in Ireland.

We have reserves for taxes to address potential exposures involving tax positions that are being challenged or that could be challenged by taxing authorities even though we believe the positions we have taken are appropriate. We believe our tax reserves are adequate to cover potential liabilities. We review the tax reserves quarterly and as circumstances warrant and adjust the reserves as events occur that affect our potential liability for additional taxes. It is often difficult to predict the final outcome or timing of resolution of any particular tax matter; and various events, some of which cannot be predicted, such as clarification of tax law by administrative or judicial means, may occur and would require us to increase or decrease our reserves and effective tax rate. We expect to record additional reserves in future periods with respect to the company’s tax filing positions. It is reasonably possible that unrecognized tax positions may decrease from $0 to $8,200 due to settlements or expiration of the statute of limitations within the next twelve months. To the extent that uncertain tax positions resolve in our favor, it could have a positive impact on our effective tax rate. A portion of reserves, which could settle or expire within the next twelve months, may result in the booking of deferred tax assets subject to a valuation allowance for which no benefit would be recognized. Income tax-related interest and penalties were a benefit of $1,560 for the year ended January 31, 2010 and an expense of $3,122 for the year ended January 31, 2009.

The liability for uncertain tax positions (including liabilities for associated interest and penalties and excluding uncertain tax positions that resulted in credits or net operating losses) was $36,791 as of January 31, 2010 and $59,078 as of January 31, 2009. Further, we have recorded deferred tax assets in the amounts of $592 as of January 31, 2010 and $2,451 as of January 31, 2009, for offsetting tax benefits that would result from the ability to sustain the uncertain tax position. The offsetting tax benefits include deductible state income taxes and interest, and other deductible tax adjustments. We expect $33,018 of the reserve for the uncertain tax positions, if recognized, would favorably affect our effective tax rate. As of January 31, 2010, the full reserve for taxes of $36,791 was reflected in income tax liability.

The total gross amount of unrecognized tax benefits was $39,910 as of January 31, 2010 and $60,765 as of January 31, 2009, which excludes accrued interest and penalties related to such positions of $9,067 as of January 31, 2010 and $10,811 as of January 31, 2009. These amounts represent the gross amount of exposure in individual jurisdictions and do not reflect any additional benefits expected to be realized if such positions were not sustained, such as the federal deduction that could be realized if an unrecognized state deduction was not sustained.

12. Commitments and Contingencies

Leases

We lease a majority of our field sales offices and research and development facilities under non-cancelable operating leases. In addition, we lease certain equipment used in our research and development activities. This equipment is generally leased on a month-to-month basis after meeting a six-month lease minimum.

Future minimum lease payments under all non-cancelable operating leases are approximately as follows:

Fiscal years ending January 31,
2011	$	28,713
2012		16,205
2013		10,564
2014		7,181
2015		5,374
Thereafter		10,684
Total	$	78,721

Rent expense under operating leases was $32,283 for the year ended January 31, 2010, $33,225 for fiscal 2009, and $34,197 for fiscal 2008.

We entered into agreements to sublease portions of our facility sites. Rental income under these agreements was $1,497 for the year ended January 31, 2010, $1,401 for fiscal 2009, and $1,266 for fiscal 2008. Under terms of these agreements we expect future rental receipts of $1,480 in fiscal 2011, $263 in fiscal 2012, $265 in fiscal 2013, $137 in fiscal 2014, and none in fiscal 2015.

Income Taxes

As of January 31, 2010, we had a liability of approximately $36,791 for income taxes associated with uncertain income tax positions. All of these tax positions are classified as long-term liabilities in our Consolidated Balance Sheet, as we generally do not anticipate the settlement of the liabilities will require payment of cash within the next twelve months. Further, certain liabilities may result in the reduction of deferred tax assets rather than settlement in cash. We are not able to reasonably estimate the timing of any cash payments required to settle these liabilities and do not believe that the ultimate settlement of these obligations will materially affect our liquidity.

Indemnifications

Our license and services agreements generally include a limited indemnification provision for claims from third parties relating to our intellectual property. The indemnification is generally limited to the amount paid by the customer or a set cap. As of January 31, 2010, we were not aware of any material liabilities arising from these indemnifications.

67

Legal Proceedings

From time to time, we are involved in various disputes and litigation matters that arise from the ordinary course of business. These include disputes and lawsuits relating to intellectual property rights, contracts, distributorships, and employee relations matters. Periodically, we review the status of various disputes and litigation matters and assess each potential exposure. When we consider the potential loss from any dispute or legal matter probable and the amount or the range of loss can be estimated, we will accrue a liability for the estimated loss. Legal proceedings are subject to uncertainties and the outcomes are difficult to predict. Because of such uncertainties, we base accruals on the best information available at the time. As additional information becomes available, we reassess the potential liability related to pending claims and litigation matters and may revise estimates. We believe that the outcome of current litigation, individually and in the aggregate, will not have a material affect on our results of operations.

13. Employee Stock and Savings Plans

Stock Options Plans and Stock Plans

We have two common stock option plans which provide for the granting of incentive stock options (ISOs), nonqualified stock options (NQSOs), stock appreciation rights (SARs), restricted stock, restricted stock units, and performance-based awards. The two common stock option plans are administered by the Compensation Committee of our Board of Directors and permit accelerated vesting of outstanding options upon the occurrence of certain changes in control of our company.

The 1982 Stock Option Plan was adopted by our Board of Directors and approved by our shareholders in 1982. This plan allows for the granting of ISOs, NQSOs, SARs, restricted stock, restricted stock units, and performance-based awards to our officers and key employees. Options issued under this plan generally vest over four years, have an expiration date of 10 years from the date of grant, and an exercise price not less than the fair market value of the shares on the date of grant. A total of 32,670 shares of common stock have been authorized for grant with 4,629 shares available for future grant as of January 31, 2010.

The Non-Qualified Stock Option Plan was adopted by our Board of Directors and approved by our shareholders in 1983. This plan allows for the granting of NQSOs and SARs to our officers and key employees. Options issued under this plan generally vest over four years, have an expiration date of 10 years from the date of grant, and an exercise price not less than the fair market value of the shares on the date of grant. A total of 1,540 shares of common stock have been authorized for grant, with 32 shares available for future grant as of January 31, 2010.

We also have a stock plan that provides for the sale of common stock to officers, key employees, and non-employee consultants. The 1986 Stock Plan was adopted by our Board of Directors in 1986. This plan allows for shares to be awarded at no purchase price as a stock bonus, or with a purchase price as a NQSO. Stock options issued under the plan have an expiration date of 10 years from the date of grant. All other terms of the awards, including the exercise price, are at the sole discretion of the Compensation Committee. A total of 19,500 shares of common stock have been authorized for grant, with 1,842 shares available for future grant as of January 31, 2010.

The 1987 Non-Employee Directors’ Stock Plan was adopted by our Board of Directors and approved by our shareholders in 1987. This plan provides for the annual grant to each non-employee director of either an option for 21 shares of common stock or 7 shares of restricted stock, each vesting over a period of five years but with accelerated vesting upon any termination of service. Stock options issued under this plan have an expiration date of 10 years from the date of grant and an exercise price equal to the last price reported on The NASDAQ Global Select Market on the grant date. A total of 1,500 shares of common stock have been authorized for grant, with 258 shares available for future grant as of January 31, 2010.

We assumed the stock plan of an acquired company during the year ended January 31, 2010. Options issued under this plan vest over four years from the date of the exchanged options grant, have an expiration date of 10 years from the date of the exchanged options grant, and an exercise price based on the exchange ratio of the exchanged shares exercise price. This stock plan has been suspended and no future awards will be granted under this plan. A total of 285 shares of common stock have been authorized and granted.

As of January 31, 2010, a total of 55,495 shares of common stock were authorized under all five plans, with 6,761 shares available for future grant.

On December 6, 2007, the Compensation Committee approved the extension of the expiration dates of all outstanding stock options remaining from those granted on March 26, 1998 with an exercise price of $10.0625 per share, and on March 17, 1999 with an exercise price of $12.5625 per share. The original expiration dates for these options were February 28, 2008 and February 28, 2009, respectively. These options were amended to extend the expiration dates to the tenth anniversary of the grant dates, which was March 26, 2008 (extended by 27 days), and

68

March 17, 2009 (extended by 17 days), respectively. Due to the change in our fiscal year, announcement of our year-end earnings was expected to occur close to February 28 each year and the expiration date extensions move the option expirations further away from our announcement of earnings. A total of 550 options held by 152 employees were extended from the March 26, 1998 grant and a total of 589 options held by 235 employees were extended from the March 17, 1999 grant. Total incremental cost of $77 resulted from modification of the March 26, 1998 grant and total incremental cost of $32 resulted from the modification of the March 17, 1999 grant.

In August 2008, we modified 5,855 stock options to extend the exercise period from 30 days to 12 months upon the occurrence of both a change in control and certain other triggering events. The modification was valued at $880. We recognized expense of $94 for the year ended January 31, 2010 and $682 for fiscal 2009. The balance of the expense will be amortized over two years.

Stock options outstanding, the weighted average exercise price, and transactions involving the stock option plans are summarized as follows:

Employee Stock Purchase Plans

We have an employee stock purchase plan (ESPP) for U.S. employees and an ESPP for certain foreign subsidiary employees. The ESPPs generally provide for overlapping two-year offerings starting every six months on January 1 and July 1 of each year with purchases every six months during those offerings. Each eligible employee may purchase up to six thousand shares of stock on each purchase date at prices no less than 85% of the lesser of the fair market value of the shares at the beginning of the two-year offering period or on the applicable purchase date. As of January 31, 2010, 7,394 shares remain available for future purchase under the ESPPs. The plans will expire upon either issuance of all shares reserved for issuance or at the discretion of our Board of Directors. The following table summarizes shares issued under the ESPPs:

Weighted average purchase price per share	$	4.40	$	6.08	$	9.04

Stock-Based Compensation Expense

We estimate the fair value of stock options and purchase rights under our ESPPs using a Black-Scholes option-pricing model. The Black-Scholes option-pricing model incorporates several highly subjective assumptions including expected volatility, expected term, and interest rates.

In reaching our determination of expected volatility for options we include the following elements:

• Historical volatility of our shares of common stock;

• Historical volatility of shares of comparable companies;

• Implied volatility of our traded options; and

• Implied volatility of traded options of comparable companies.

In reaching our determination of expected volatility for purchase rights under our employee stock plans, we use the historical volatility of our shares of common stock.

We base the expected term of our stock options on historical experience.

The risk-free interest rate for periods within the contractual life of the award is based on the U.S. Treasury yield curve in effect at the time of the grant.

The fair value of restricted stock units is the market value as of the grant date.

The weighted average grant date fair values are summarized as follows:

Year ended January 31,	2010		2009		2008
Options granted	$	4.06	$	2.79	$	7.54
Restricted stock granted	$	8.78	$	15.29	$	13.61
ESPP purchase rights	$	2.77	$	4.43	$	4.18

The fair value calculations used the following assumptions:

We issued 222 shares of common stock valued at $3,014 to the founders of a company we acquired in June 2007. These shares were subject to forfeiture if their employment terminated prior to June 2009. The value of these shares were amortized over a two year period.

The following table summarizes stock-based compensation expense included in the results of operations and the tax benefit associated with the exercise of stock options:

Year ended January 31,	2010			2009		2008
Cost of revenues:
Service and support	$	1,618		$	1,544	$	964
Operating expense:
Research and development		10,931			12,005		7,880
Marketing and selling		8,406			8,627		5,525
General and administration		5,204			6,047		4,107
Equity plan-related compensation expense (1)	$	26,159		$	28,223	$	18,476
Tax effect of the exercise of stock options	$	(96	)	$	93	$	85

(1) Equity plan-related compensation expense for the year ended January 31, 2010 includes $25,657 relating to stock options, stock awards, and the ESPPs and $502 relating to the amortization of expense associated with stock issued to the founders of a company we acquired during the year ended January 31, 2008. Equity plan-related compensation expense for fiscal 2009 includes $26,716 relating to stock options, stock awards, and the ESPPs and $1,507 relating to the amortization of expense associated with stock issued to the founders of a company we acquired during the year ended January 31, 2008. Equity plan-related compensation expense for fiscal 2008 includes $17,472 relating to stock options, stock awards, and the ESPPs and $1,004 relating to the amortization of expense associated with stock issued to the founders of a company we acquired during the year ended January 31, 2008.

As of January 31, 2010, we had $20,889 in unrecognized compensation cost related to nonvested awards which is expected to be recognized over a weighted average period of 2.23 years.

Employee Savings Plan

We have an employee savings plan (the Savings Plan) that qualifies as a deferred salary arrangement under Section 401(k) of the Internal Revenue Code. Under the Savings Plan, participating U.S. employees may defer a portion of their pretax earnings, up to the IRS annual contribution limit. We currently match 50% of eligible employee’s contributions, up to a maximum of 6% of the employee’s earnings. Employer matching contributions vest over five years, 20% for each year of service completed. Our matching contributions to the Savings Plan were $4,928 for the year ended January 31, 2010, $5,910 for fiscal 2009, and $5,972 for fiscal 2008.

14. Common Stock Warrants

On February 22, 2002, as part of the purchase price for an acquisition, we issued warrants to purchase 50 shares of our common stock for $20.77 per share, exercisable from February 15, 2006 until February 14, 2012. All warrants issued remain outstanding as of January 31, 2010.

15. Net Income (Loss) Per Share

We compute basic net income (loss) per share using the weighted average number of common shares outstanding during the period. We computed diluted net loss per share using the weighted average number of common shares and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares consist of common shares issuable upon exercise of stock options, purchase rights from ESPPs, and warrants using the treasury stock method and common shares issuable upon conversion of subordinated debentures, if dilutive.

72

The following provides the computation of basic and diluted net income (loss) per share:

Year ended January 31,	2010			2009			2008
Net income (loss)	$	(21,889	)	$	(91,252	)	$	24,309
Weighted average common shares used to calculate basic net income (loss) per share		96,474			91,829			88,086
Employee stock options and employee stock purchase plans		–			–			1,895
Weighted average common and potential common shares used to calculate diluted net income (loss) per share		96,474			91,829			89,981
Basic net income (loss) per share	$	(0.23	)	$	(0.99	)	$	0.28
Diluted net income (loss) per share	$	(0.23	)	$	(0.99	)	$	0.27

We excluded from the computation of diluted net income (loss) per share options, warrants, and ESPP purchase rights to purchase 19,382 shares of common stock for the year ended January 31, 2010, 20,995 for fiscal 2009, and 11,542 for fiscal 2008. The options, warrants, and ESPP purchase rights were anti-dilutive either because we incurred a net loss for the period, the warrant price was greater than the average market price of the common stock during the period, or the option was determined to be anti-dilutive as a result of applying the treasury stock method.

The effect of the conversion of the Floating Rate Debentures and the 6.25% Debentures was anti-dilutive and therefore excluded from the computation of diluted net income (loss) per share. We assume that the 6.25% Debentures will be settled in common stock for purposes of calculating the dilutive effect of the 6.25% Debentures. If the Floating Rate Debentures and the 6.25% Debentures had been dilutive we would have included additional income and additional incremental common shares as shown in the following table:

Year ended January 31,	2010		2009		2008
Floating Rate Debentures
Additional income	$	633	$	1,144	$	2,109
Additional incremental common shares		1,415		1,543		1,821
Year ended January 31,	2010		2009		2008
6.25% Debentures
Additional income	$	2,643	$	2,643	$	2,643
Additional incremental common shares (1)		–		–		–

(1) Dilutive net income (loss) would have included no incremental shares for the years ended January 31, 2010, 2009, or 2008 as the stock price was below the conversion rate.

The conversion features of the 6.25% Debentures, which allow for settlement in cash, common stock, or a combination of cash and common stock, are further described in Note 10. “Notes Payable.”

16. Accumulated Other Comprehensive Income

The following tables summarize the components of Accumulated other comprehensive income:

17. Special Charges

The following is a summary of the components of the special charges:

Year ended January 31,	2010		2009		2008
Employee severance and related costs	$	10,713	$	9,792	$	9,676
Excess leased facility costs		2,530		2,548		(508	)
Acquisitions		2,067		–		–
Other		6,024		4,548		980
Total special charges	$	21,334	$	16,888	$	10,148

Special charges primarily consists of costs incurred for employee terminations and were due to a reduction of personnel resources driven by modifications of business strategy or business emphasis. Special charges may also include expenses incurred related to potential acquisitions, excess facility costs, and asset related charges.

Employee severance and related costs of $10,713 for the year ended January 31, 2010 included severance benefits, notice pay, and outplacement services. The total rebalance charge represents the aggregate of numerous unrelated rebalance plans which impacted several employee groups, none of which was individually material to our financial position or results of operations. We determined termination benefit amounts based on employee status, years of service, and local statutory requirements. We communicated termination benefits to the affected employees prior to the end of the quarter in which we recorded the charge. Approximately 83% of these costs were paid during the year ended January 31, 2010. We expect to pay the remainder during fiscal 2011. There have been no significant modifications to the amount of these charges.

Excess leased facility costs of $2,530 for the year ended January 31, 2010 were primarily due to the abandonment of leased facilities and changes in the estimate of sublease income for previously abandoned leased facilities.

74

Acquisition costs of $2,067 for the year ended January 31, 2010 represent legal and other costs related to acquisitions and potential acquisitions. In accordance with the FASB’s revised guidance on business combinations, we expensed acquisition costs in the period in which the costs were incurred for the year ended January 31, 2010. Prior to fiscal 2010, acquisition costs were included in consideration transferred for the acquisition.

Other special charges for the year ended January 31, 2010 included costs of $4,700 for advisory fees, charges of $566 for a casualty loss, charges of $405 related to an asset abandonment, charges of $302 for facility restoration and other charges of $51.

(1) Of the $9,024 total accrued special charges as of January 31, 2010, $1,515 represented the long-term portion of accrued lease termination fees and other facility costs, net of sublease income. The remaining balance of $7,509 represented the short-term portion of accrued special charges.

Employee severance and related costs of $9,792 for the year ended January 31, 2009 included severance benefits, notice pay, and outplacement services. The total rebalance charge represents the aggregate of numerous unrelated rebalance plans which impacted several employee groups, none of which was individually material to our financial position or results of operations.

We communicated termination benefits to the affected employees prior to the end of the quarter in which we recorded the charge. Approximately 93% of these costs were paid as of January 31, 2010. We expect to pay the remainder during fiscal 2011. There have been no significant modifications to the amount of these charges.

Excess leased facility costs of $2,548 for the year ended January 31, 2009 were primarily due to the abandonment of leased facilities and changes in the estimate of sublease income for previously abandoned leased facilities.

Other special charges for the year ended January 31, 2009 included costs of $4,535 for advisory fees and costs of $13 for the closure of a division.

Employee severance and related costs of $9,676 for the year ended January 31, 2008 included severance benefits, notice pay, and outplacement services. The total rebalance charge represents the aggregate of numerous unrelated rebalance plans which impacted several employee groups, none of which was individually material to our financial position or results of operations. We determined termination benefit amounts based on employee status, years of service, and local statutory requirements. We communicated termination benefits to the affected employees prior to the end of the quarter in which we recorded the charge. Costs remaining as of January 31, 2009 were paid in fiscal 2010.

75

Excess leased facility costs of $(508) for the year ended January 31, 2008 was primarily due to the reoccupancy of a previously abandoned leased facility and the termination of an abandoned facility lease in a lease buyout. The cost of the lease buyout was less than the remaining balance of the accrual, resulting in an adjustment to Special charges.

Other special charges for the year ended January 31, 2008 included costs of $953 related to the abandonment of an information technology project, costs of $99 for the termination of a service agreement related to a subsidiary that was legally merged with one of our other subsidiaries located in the same country, and a benefit of $72 related to a liability, arising from a previous acquisition, which was favorably settled.

19. In-Process Research and Development

We incurred $13,985 of in-process research and development charges during fiscal 2009 related to undeveloped technology acquired through a joint development agreement with IBM addressing technological challenges of integrated circuit design at 22 nanometer geometries. We based the value of the charge on the present value of the four year payment obligation as defined in the agreement. We made payments of $5,000 during fiscal 2010 and are required to make annual payments of $2,500 during each of fiscal 2011 through fiscal 2013. The joint development agreement provides access to technology which has not yet reached technological feasibility and provides no alternative future use. The technology is expected to be the basis for a new offering in our Calibre^® product family once development is completed.

Other in-process research and development charges for fiscal 2009 and fiscal 2008 relate to acquisitions of businesses. See further discussion of these amounts in Note 6. “Business Combinations.”

22. Segment Reporting

We operate exclusively in the EDA industry. We market our products and services worldwide, primarily to large companies in the military/aerospace, communications, computer, consumer electronics, semiconductor, networking, multimedia, and transportation industries. We sell and license our products through our direct sales force in North America, Europe, Japan, and the Pacific Rim and through distributors where third parties can extend sales reach more effectively or efficiently. Our Chief Operating Decision Makers (CODMs), which consist of the Chief Executive Officer and the President, review our consolidated results within one operating segment. In making operating decisions, our CODMs primarily consider consolidated financial information accompanied by disaggregated information by geographic region.

We eliminate all intercompany revenues and expenses in computing Revenues, Operating income (loss), and Income (loss) before income tax. The corporate component of Operating income (loss) represents research and development, corporate marketing and selling, corporate general and administration, special charges, impairment of long-lived assets, and, prior to the year ended January 31, 2010, in-process research and development charges.

We adopted new accounting principles for our 6.25% Convertible Subordinated Debentures due 2026 on February 1, 2009. This adoption required retrospective application and as such, the fiscal 2009 quarterly results have been adjusted to reflect post-adoption results. See Note 3. “Change in Accounting” for additional information and disclosures related to this adoption.

24. Subsequent Events

On January 7, 2010 we extended a tender offer to exchange eligible stock options for restricted stock units. Executives and members of the Board of Directors were excluded from participating in the stock option exchange. The stock option exchange program was approved by shareholders on December 14, 2009. The offer expired February 5, 2010. Pursuant to the exchange offer, 6,945 eligible options were tendered, representing 77.3% of the total stock options eligible for the exchange. On February 8, 2010 we granted an aggregate of 557 restricted stock units in exchange for the stock options surrendered in the exchange offer.

In October 2009, we signed a definitive merger agreement to acquire Valor Computerized Systems, Ltd. (Valor), a provider of productivity improvement software solutions for the printed circuit board manufacturing supply chain. In February 2010, the shareholders of Valor approved our proposed acquisition. Under the terms of the agreement, Valor shareholders will receive approximately 5,600 shares of our common stock and cash for aggregate consideration of approximately $80,000. We anticipate that this transaction will close during the first quarter of fiscal 2011. In anticipation of the acquisition, in February 2010, we borrowed $30,000 under our revolving credit facility. We expect to repay the $30,000 during the next twelve months.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders

Mentor Graphics Corporation:

We have audited the accompanying consolidated balance sheets of Mentor Graphics Corporation and subsidiaries as of January 31, 2010 and 2009, and the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the years in the three-year period ended January 31, 2010. In connection with our audits of the consolidated financial statements, we also have audited financial statement Schedule II. These consolidated financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Mentor Graphics Corporation and subsidiaries as of January 31, 2010 and 2009, and the results of their operations and their cash flows for each of the years in the three-year period ended January 31, 2010, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

As discussed in Note 3 to the consolidated financials statements, the Company changed its method of accounting for its 6.25% Convertible Subordinated Debentures due to the retrospective adoption of new accounting requirements issued by the Financial Accounting Standards Board, as of February 1, 2009.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Mentor Graphics Corporation’s internal control over financial reporting as of January 31, 2010, based on criteria established inInternal Control—Integrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated March 17, 2010, expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Item 9A. Controls and Procedures

(1)Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended (the Exchange Act). Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with United States generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

82

Management assessed the effectiveness of our internal control over financial reporting as of January 31, 2010, and has concluded that our internal control over financial reporting was effective. In making its assessment of internal control over financial reporting, management used the criteria issued by the Committee of Sponsoring Organizations of the Treadway Commission inInternal Control-Integrated Framework.

Our independent registered public accounting firm, KPMG LLP, has audited our internal control over financial reporting as of January 31, 2010, as stated in their report included in this Annual Report on Form 10-K.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders

Mentor Graphics Corporation:

We have audited Mentor Graphics Corporation’s internal control over financial reporting as of January 31, 2010, based on criteria established inInternal Control—Integrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Mentor Graphics Corporation’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Mentor Graphics Corporation maintained, in all material respects, effective internal control over financial reporting as of January 31, 2010, based on criteria established inInternal Control—Integrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Mentor Graphics Corporation and subsidiaries as of January 31, 2010 and 2009, and the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the years in the three-year period ended January 31, 2010, and our report dated March 17, 2010 expressed an unqualified opinion on those consolidated financial statements.

(2) Changes in Internal Control Over Financial Reporting

There has been no change in our internal control over financial reporting that occurred during the last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

(3) Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures, as defined by Exchange Act Rules 13a–15(e) and 15d-15(e), that are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this report. Based on the foregoing, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of the end of the period covered by this report.
