PART I

Introduction

Synopsys, Inc. is a global leader in providing software, intellectual property and services used to design integrated circuits and electronic systems. For more than 25 years, we have supplied the electronic design automation (EDA) software that engineers use to design and test integrated circuits (ICs), commonly called chips. We also provide software and hardware used to develop the electronic systems that incorporate chips and the software that runs on those chips. Our intellectual property (IP) products are pre-designed circuits that engineers use as components of larger chip designs instead of designing those circuits themselves. To complement these product offerings, we provide technical services to support our solutions and help our customers develop chips and electronic systems.

Corporate Information

We incorporated in 1986 in North Carolina and reincorporated in Delaware in 1987. Our headquarters are located at 700 East Middlefield Road, Mountain View, California 94043, and our telephone number there is (650) 584-5000. We have approximately 81 offices worldwide.

Our annual and quarterly reports on Forms 10-K and 10-Q (including related filings in XBRL format), current reports on Form 8-K, and Proxy Statements relating to our annual meetings of stockholders, including any amendments to these reports, as well as filings made by our executive officers and directors, are available through our Internet website (www.synopsys.com) free of charge as soon as practicable after we file them with, or furnish them to, the SEC (www.sec.gov). The contents of our website are not part of this Form 10-K.

Background

Recent years have seen a remarkable proliferation of consumer and wireless electronic products, particularly mobile devices. The growth of the Internet and cloud computing has provided people with new ways to create, store and share information. At the same time, the increasing use of electronics in cars, buildings, appliances and other consumer products is expanding the landscape of “smart” devices.

These developments depend, in large part, on chips. It is common for a single chip to combine many components (processor, communications, memory, custom logic, input/output) into a single System-on-Chip (SoC), resulting in highly complex chip designs. The most complex chips today contain more than a billion transistors, the basic building blocks for integrated circuits, each of which may have features that are less than 1/1,000th the diameter of a human hair. At such small dimensions, the wavelength of light itself can become an obstacle to production, becoming too big to create such dense features and requiring creative and complicated new approaches from designers. Designers have turned to new manufacturing techniques, such as double patterning lithography and 3D FinFET transistors, which introduce their own challenges in design and production.

In addition, due to the popularity of mobile devices and other electronic products, there is increasing demand for integrated circuits and systems with greater functionality and performance, reduced size, and less power consumption. The designers of these products—our customers—are facing intense pressure to deliver innovative products at ever shorter times-to-market, as well as at lower prices. In other words, innovation in chip and system design today often hinges on “better,” “sooner,” and “cheaper.”

Synopsys is at the heart of accelerating innovation in the dynamic electronics market. We provide the software tools, IP, hardware and other technologies that designers use to create chips and

systems. The designer’s task is to determine how best to locate and connect the building blocks of chips, verifying that the resulting design behaves as intended and ensuring that the design can be manufactured efficiently and cost-effectively. This task is a complicated, multi-step process that is both expensive and time-consuming.

We offer a wide range of products that help designers at different steps in the overall design process, both for the design of individual integrated circuits and for the design of larger systems. Our products can increase designer productivity and efficiency by automating tasks, keeping track of large amounts of design data, adding intelligence to the design process, facilitating reuse of past designs and reducing errors. Our IP products offer proven, high-quality pre-configured circuits that are ready-to-use in a chip design, saving customers time and enabling them direct resources to projects that differentiate their products. Our global service and support engineers also provide expert technical support and design assistance to our customers.

Products and Services

Revenue from our products and services is reported in four groups: Core EDA, which includes the Galaxy™ Design Platform, the Discovery™ Verification Platform and our FPGA (Field Programmable Gate Array) design products; IP and System-Level Solutions; Manufacturing Solutions; and Professional Services.

Core EDA Solutions

The process of designing integrated circuits contains many complex steps: architecture definition, RTL (register transfer level) design, functional/RTL verification, logic design or synthesis, gate-level verification, floorplanning, and place and route, to name just a few. Designers use our Core EDA products to automate the integrated circuit design process and to reduce errors. We offer a large number of Core EDA products intended to address the process comprehensively. Our Core EDA products generally fall into the following suites: the Galaxy Design Platform, which includes tools to design an integrated circuit, the Discovery Verification Platform, which includes tools to verify that an integrated circuit behaves as intended, and FPGA design products.

Galaxy Design Platform

Our Galaxy Design Platform provides our customers with a single, integrated chip design solution that includes industry-leading individual products and incorporates common libraries and consistent timing, delay calculation and constraints throughout the design process. The platform allows designers the flexibility to integrate internally developed and third-party tools. With this advanced functionality, common foundation and flexibility, our Galaxy Design Platform helps reduce design times, decrease integration costs and minimize the risks inherent in advanced, complex integrated circuit designs. Our products span both digital and analog/mixed-signal designs.

The principal products included in the Galaxy Design Platform are our IC Compiler™ physical design solution, Design Compiler^® logic synthesis product, Galaxy Custom Designer^® physical design solution for analog/mixed-signal designs, PrimeTime^® timing analysis products, StarRC™ product for extraction, and IC Validator tool for physical verification.

Discovery Verification Platform

Our Discovery Verification Platform is a comprehensive, integrated portfolio of functional, analog/mixed-signal, formal and low-power verification products. The platform includes design-for-verification methodologies and provides a consistent control environment to help significantly improve the speed, breadth and accuracy of our customers’ functional and mixed-signal verification efforts. The Discovery Verification Platform’s components support industry standards and are tightly coupled together through direct kernel integration for highest throughput mixed-signal simulation.

We also offer ZeBu^® emulation systems that use high-performance, high-bandwidth hardware to emulate SoC designs so that designers can co-verify and debug the behavior of the SoC, and software running on the SoC, prior to its production.

FPGA Design Products

FPGAs are complex chips that can be customized or programmed to perform a specific function after they are manufactured. For FPGA design, we offer Synplify^® Pro and Premier implementation and Identify^® debug software tools.

IP and System-Level Solutions

IP Products

As more functionality converges into a single device or even a single chip, and chip designs grow more complex, the number of third-party IP blocks incorporated into designs is rapidly increasing. Synopsys is a leading provider of high-quality, silicon-proven IP solutions for SoCs. Our broad DesignWare^® IP portfolio includes:

System-Level Solutions

Optimizing the system-level design earlier in the development cycle, including both hardware and software components, is increasingly important for customers to meet their performance, time-to-market, and development cost goals. Synopsys has the industry’s broadest portfolio of tools, models and services for the system-level design of SoCs.

Our Platform Architect™ software enables early and rapid exploration of SoC architectural trade-offs. To speed the creation, implementation and verification of differentiated IP blocks, we offer SPW™ and System Studio™ tools for algorithm design, Processor Designer™ software for custom processor design, and Synphony Model™ and C Compilers for high-level synthesis.

Escalating software content and complexity in today’s electronic devices are driving the adoption of new tools and methods to accelerate software development and ease hardware-software integration and system validation. Our system-level portfolio includes prototyping technologies that improve the productivity of both hardware and software development teams. Our Virtualizer™ tool and broad portfolio of transaction-level models enable the creation of virtual prototypes, fully functional software models of complete systems that enable engineers to start software development up to twelve months earlier than traditional methods. Our HAPS^® FPGA-based prototyping systems integrate high performance hardware and software tools with real-world interfaces to enable faster hardware-software integration and full system validation. Our hybrid prototyping solution combines both approaches to prototyping, integrating Virtualizer virtual prototyping with HAPS FPGA-based prototyping.

Our CODE V^® solution enables engineers to model, analyze and optimize designs for optical imaging and communication systems. Our LightTools^® design and analysis software allows designers to simulate and improve the performance of a broad range of illumination systems, from vehicle lighting to projector systems.

Manufacturing Solutions

Our Manufacturing Solutions products and technologies enable semiconductor manufacturers to more quickly develop new fabrication processes that produce production-level yields. These products are used in the early research and development phase and the production phase. In the production phase, manufacturers use these products to convert IC design layouts into the masks used to manufacture the devices.

Our Manufacturing Solutions include Sentaurus™ Technology-CAD (TCAD) device and process simulation products, Proteus optical proximity correction (OPC) and lithography rule check (LRC) products, CATS^® mask data preparation product, and Yield Explorer^® and Odyssey Yield Management solutions.

Professional Services and Training

Synopsys provides consulting and design services that address all phases of the SoC development process. These services assist our customers with new tool and methodology adoption, chip architecture and specification development, functional and low-power design and verification, and physical implementation and signoff. We also provide a broad range of expert training and workshops on our latest tools and methodologies.

Customer Service and Technical Support

A high level of customer service and support is critical to the adoption and successful use of our products. We provide technical support for our products through both field-based and corporate-based application engineering teams. Customers who purchase Technology Subscription Licenses (TSLs) receive software maintenance services bundled with their license fee. Customers who purchase term licenses and perpetual licenses may purchase these services separately. See Product Sales and Licensing Agreements below.

Software maintenance services include minor product enhancements, bug fixes and access to our technical support center for primary support. Software maintenance also includes access to the SolvNet^® portal, our web-based support solution that gives customers access to Synopsys’ complete design knowledge database. Updated daily, the SolvNet portal includes documentation, design tips and answers to user questions. Customers can also engage, for additional charges, our worldwide network of applications consultants for additional support needs.

In addition, Synopsys also offers training workshops designed to increase customer design proficiency and productivity with our products. Workshops cover our products and methodologies used in our design and verification flows, as well as specialized modules addressing system design, logic design, physical design, simulation and test. We offer regularly scheduled public and private courses in a variety of locations worldwide, as well as Virtual Classroom on-demand and live online training.

Product Warranties

We generally warrant our products to be free from defects in media and to substantially conform to material specifications for a period of 90 days for our software products and for up to six months for our hardware products.

Support for Industry Standards

We actively create and support standards that help our customers increase productivity, facilitate efficient design flows, improve interoperability of tools from different vendors, and ensure connectivity, functionality and interoperability of IP building blocks. Standards in the electronic design industry can be established by formal accredited organizations, industry consortia, company licensing made available to all, de facto usage, or through open source licensing.

Synopsys’ products support more than 35 standards, including the most commonly used hardware description languages: SystemVerilog, Verilog, VHDL, and SystemC. Our products utilize numerous industry standard data formats, application programming interfaces, and databases for the exchange of design data among our tools, other EDA vendors’ products, and applications that customers develop internally. We also comply with a wide range of industry standards within our IP product family to ensure usability and interconnectivity.

Sales, Distribution and Backlog

Our customers are primarily semiconductor and electronics systems companies. We market our products and services principally through direct sales in the United States and principal foreign markets. We typically distribute our software products and documentation to customers electronically, but provide physical media (i.e., DVD-ROMs) when requested by the customer.

We maintain sales/support centers throughout the United States. Outside the United States, we maintain sales, support or service offices in Canada, multiple countries in Europe, Israel, Japan, China, Korea, Taiwan and other countries in Asia. Our foreign headquarters for financial and tax purposes are located in Dublin, Ireland. Our offices are further described under Part I, Item 2, Properties.

In fiscal 2013, 2012 and 2011, an aggregate of 52%, 52% and 54%, respectively, of Synopsys’ total revenue was derived from sales outside of the U.S. Geographic revenue, which is based on customer server site location, is shown below as a percentage of total revenue for the last three fiscal years:

Table of Contents

Additional information relating to domestic and foreign operations, including revenue and long-lived assets by geographic area, is contained in Note 13 of Notes to Consolidated Financial Statements in Part II, Item 8, Financial Statements and Supplementary Data. Risks related to our foreign operations are described in Part I, Item 1A, Risk Factors.

Our backlog was approximately $3.1 billion on October 31, 2013, representing a 15% increase from backlog of $2.7 billion on October 31, 2012, which resulted primarily from the renewal of large multi-year contracts in fiscal 2013. Backlog represents committed orders that are expected to be recognized as revenue over the following three years. We currently expect that $1.5 billion of our backlog will be recognized after fiscal 2014. Backlog may not be a reliable predictor of our future sales as business conditions may change and technologies may evolve, and customers may seek to renegotiate their arrangements or may default on their payment obligations. For this and other reasons, we may not be able to recognize expected revenue from backlog when anticipated.

Revenue attributable to each of our four platforms established for management reporting purposes is shown below as a percentage of total revenue for the last three fiscal years:

Revenue by Platform

Revenue derived from Intel Corporation and its subsidiaries in the aggregate accounted for 11.3%, 10.5% and 10.6% of our total revenue in fiscal 2013, 2012 and 2011, respectively.

Research and Development

Our future performance depends in large part on our ability to further enhance and extend our design and verification platforms and to expand our manufacturing, IP and system-level product offerings. Research and development on existing and new products is primarily conducted within each product group. We also use targeted acquisitions to augment our own research and development efforts.

Our research and development expenses were $669.2 million, $581.6 million and $491.9 million in fiscal 2013, 2012 and 2011, respectively. Our capitalized software development costs were approximately $3.6 million, $3.3 million and $2.9 million in fiscal 2013, 2012 and 2011, respectively.

Competition

The EDA industry is highly competitive. We compete against other EDA vendors and against our customers’ own design tools and internal design capabilities. In general, we compete principally on

7

Table of Contents

technology leadership, product quality and features (including ease-of-use), license terms, post-contract customer support, interoperability with our own and other vendors’ products, price and payment terms. No one factor drives an EDA customer’s buying decision, and we compete on all fronts to capture a higher portion of our customers’ budgets.

Our competitors include EDA vendors that offer varying ranges of products and services, such as Cadence Design Systems, Inc. and Mentor Graphics Corporation. We also compete with other EDA vendors, including frequent new entrants to the marketplace, that offer products focused on one or more discrete phases of the IC design process, as well as with customers’ internally developed design tools and capabilities. In the IP area, we compete primarily with our customers’ internally developed IP.

Product Sales and Licensing Agreements

We typically license our software to customers under non-exclusive license agreements that transfer title to the media only and restrict use of our software to specified purposes within specified geographical areas. The majority of our licenses are network licenses that allow a number of individual users to access the software on a defined network, including, in some cases, regional or global networks. License fees depend on the type of license, product mix and number of copies of each product licensed.

In many cases, we provide our customers the right to “re-mix” a portion of the software they initially licensed for other specified Synopsys products. For example, a customer may use our front-end design products for a portion of the license term and then exchange such products for back-end place and route software for the remainder of the term in order to complete the customer’s IC design. This practice helps assure the customer’s access to the complete design flow needed to design its product. The ability to offer this right to customers often gives us an advantage over competitors who offer a narrower range of products because customers can obtain more of their design flow from a single vendor. At the same time, because in such cases the customer need not obtain a new license and pay an additional license fee for the use of the additional products, the use of these arrangements could result in reduced revenue compared to licensing the individual products separately without re-mix rights.

We currently offer our software products under various license types: renewable TSLs, term licenses and perpetual licenses. For a full discussion of these licenses, see Part II, Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Estimates and Results of Operations—Revenue Background.

We typically license our DesignWare Core intellectual property products under nonexclusive license agreements that provide usage rights for specific applications. Fees under these licenses are typically charged on a per design basis plus, in some cases, royalties.

Finally, our Global Technical Services team typically provides design consulting services to our customers under consulting agreements with statements of work specific to each project.

Proprietary Rights

Synopsys primarily relies upon a combination of copyright, patent, trademark and trade secret laws and license and nondisclosure agreements to establish and protect its proprietary rights. We have a diversified portfolio of more than 2,000 United States and foreign patents issued, and we will continue to pursue additional patents in the future. Our issued patents have expiration dates through 2032. Our patents primarily relate to our products and the technology used in connection with our products. Our source code is protected both as a trade secret and as an unpublished copyrighted work. However, third parties may develop similar technology independently. In addition, effective copyright and trade secret protection may be unavailable or limited in some foreign countries. We are not significantly dependent upon any single patent, copyright, trademark or license with respect to our proprietary rights.

Table of Contents

In many cases, under our customer agreements and other license agreements, we offer to indemnify our customers if the licensed products infringe on a third party’s intellectual property rights. As a result, we may from time to time need to defend claims that our customers’ use of our products infringes on these third-party rights.

There are no family relationships among any Synopsys executive officers or directors.

A description of the risk factors associated with our business is set forth below. Investors should carefully consider these risks and uncertainties before investing in our common stock.

The continued uncertainty in the global economy, and its potential impact on the semiconductor and electronics industries in particular, may negatively affect our business, operating results and financial condition.

While the global economy is improving, there are still uncertainties surrounding the strength of the recovery. Weakness in the global economy has adversely affected consumer confidence and the growth of the semiconductor industry in recent years, causing semiconductor companies to behave cautiously and focus on their costs, including their research and development budgets, which capture spending on EDA products and services. For example, uncertainty caused by the global recession caused some of our customers to postpone their decision-making, decrease their spending and/or delay their payments to us. Continuing caution by semiconductor companies could among other things limit our ability to maintain or increase our sales or recognize revenue from committed contracts and in turn adversely affect our business, operating results and financial condition.

The global recession also impacted the banking and financial services industry, resulting in the downgrade of the credit ratings of many banks, including banks we rely on for foreign currency forward contracts, credit and banking transactions and deposit services worldwide. While recent legislation is designed to strengthen the banking industry, should any of our banking partners default on their obligations, it could adversely affect our financial results and our business.

We cannot predict when widespread global economic confidence will be restored. Events such as the timing and execution of the tapering of asset purchases by the U.S. Federal Reserve may continue to drive stock market and interest rate volatility, consumer confidence and product demand. Accordingly, our future business and financial results are subject to uncertainty, and our stock price is at risk of volatile change. If economic conditions deteriorate in the future, or, in particular, if the semiconductor industry does not grow, our future revenues and financial results could be adversely affected. Conversely, in the event of future improvements in economic conditions for our customers, the positive impact on our revenues and financial results may be deferred due to our business model.

The growth of our business depends on the semiconductor and electronics industries.

The growth of the EDA industry as a whole, and our business in particular, is dependent on the semiconductor and electronics industries. A substantial portion of our business and revenue depends

10

Table of Contents

upon the commencement of new design projects by semiconductor manufacturers and their customers. The increasing complexity of designs of SoCs and ICs, and customers’ concerns about managing costs, have previously led and in the future could lead to a decrease in design starts and design activity in general, with some customers focusing more on one discrete phase of the design process or opting for less advanced, but less risky, manufacturing processes that may not require the most advanced EDA products. Demand for our products and services could decrease and our financial condition and results of operations could be adversely affected if growth in the semiconductor and electronics industries slows or stalls. Additionally, as the EDA industry matures, consolidation may result in stronger competition from companies better able to compete as sole source vendors. This increased competition may cause our revenue growth rate to decline and exert downward pressure on our operating margins, which may have an adverse effect on our business and financial condition.

Furthermore, the semiconductor and electronics industries have become increasingly complex ecosystems. Many of our customers outsource the manufacture of their semiconductor designs to foundries. Our customers also frequently incorporate third-party IP, whether provided by us or other vendors, into their designs to improve the efficiency of their design process. We work closely with major foundries to ensure that our EDA, IP, and manufacturing solutions are compatible with their manufacturing processes. Similarly, we work closely with other major providers of semiconductor IP, particularly microprocessor IP, to optimize our EDA tools for use with their IP designs and to assure that their IP and our own IP products, which may each provide for the design of separate components on the same chip, work effectively together. If we fail to optimize our EDA and IP solutions for use with major foundries’ manufacturing processes or major IP providers’ products, or if our access to such foundry processes or third-party IP products is hampered, then our solutions may become less desirable to our customers, resulting in an adverse effect on our business and financial condition.

We may not be able to realize the potential financial or strategic benefits of the acquisitions we complete, or find suitable target businesses and technology to acquire, which could hurt our ability to grow our business, develop new products or sell our products.

Acquisitions are an important part of our growth strategy. We have completed a significant number of acquisitions in recent years. We expect to make additional acquisitions in the future, but we may not find suitable acquisition targets or we may not be able to consummate desired acquisitions due to unfavorable credit markets or other risks, which could harm our operating results. Acquisitions are difficult, time-consuming, and pose a number of risks, including:

11

Table of Contents

If we do not manage these risks, the acquisitions that we complete may have an adverse effect on our business and financial condition. Additionally, if we determine we cannot use or sell the acquired products or technology, we will be required to write down the associated intangible assets, which would negatively impact our operating results.

Consolidation among our customers, as well as within the industries in which we operate, may negatively impact our operating results.

A number of business combinations, including mergers, asset acquisitions and strategic partnerships, among our customers and in the semiconductor and electronics industries have occurred recently, and more could occur in the future. Consolidation among our customers could lead to fewer customers or the loss of customers, increased customer bargaining power, or reduced customer spending on software and services. Moreover, business combinations within the industries in which we compete may result in stronger competition from companies that are better able to compete as sole source vendors to customers. The loss of customers or reduced customer spending could adversely affect our business and financial condition.

In addition, we and our competitors from time to time acquire business and technologies to complement and expand our respective product offerings. If any of our competitors consolidate or acquire businesses and technologies which we do not offer, they may be able to offer a larger technology portfolio, a larger support and service capability, or lower prices, which could negatively impact our business and operating results.

Changes in accounting principles or standards, or in the way they are applied, could result in unfavorable accounting charges or effects and unexpected financial reporting fluctuations, and could adversely affect our reported operating results.

We prepare our consolidated financial statements in conformity with U.S. Generally Accepted Accounting Principles (GAAP). These principles are subject to interpretation by the SEC and various bodies formed to interpret and create appropriate accounting principles and guidance. A change in existing principles or guidance can have a significant effect on our reported results and may retroactively affect previously reported results. Accounting standard changes could have a significant impact on our revenues and expenses, may require costly changes to our operational processes, and could cause unexpected financial reporting fluctuations.

For example, the Financial Accounting Standards Board (FASB) is currently working together with the International Accounting Standards Board (IASB) to converge certain accounting principles and facilitate more comparable financial reporting between companies that are required to follow GAAP and those that are required to follow International Financial Reporting Standards (IFRS). These efforts may result in different accounting principles under GAAP, which may have a material impact on the way in which we report financial results in areas including, but not limited to, revenue recognition, lease accounting, and financial statement presentation. The SEC may make a determination in the future regarding the incorporation of IFRS into the financial reporting system for U.S. companies. A change in accounting principles from GAAP to IFRS or to converged accounting principles may have a material impact on our financial statements and may retroactively adversely affect previously reported transactions.

Our operating results may fluctuate in the future, which may adversely affect our stock price.

Our operating results are subject to quarterly and annual fluctuations, which may adversely affect our stock price. Our historical results should not be viewed as indicative of our future performance due to these periodic fluctuations. Many factors may cause our revenue or earnings to fluctuate, including:

These factors, or any other factors or risks discussed herein, could negatively impact our revenue or earnings and cause our stock price to decline.

We operate in highly competitive industries, and if we do not continue to meet our customers’ demand for innovative technology at lower costs, our business and financial condition will be harmed.

We compete against EDA vendors that offer a variety of products and services, such as Cadence Design Systems, Inc. and Mentor Graphics Corporation. We also compete with other EDA vendors, including frequent new entrants to the marketplace, that offer products focused on one or more discrete phases of the IC design process, as well as vendors of IP products and system-level solutions. Moreover, our customers internally develop design tools and capabilities that compete with our products.

13

Table of Contents

The industries in which we operate are highly competitive and the demand for our products and services is dynamic and depends on a number of factors, including demand for our customers’ products, design starts and our customers’ budgetary constraints. Technology in these industries evolves rapidly and is characterized by frequent product introductions and improvements and changes in industry standards and customer requirements. Semiconductor device functionality requirements continually increase while feature widths decrease, substantially increasing the complexity, cost and risk of chip design and manufacturing. At the same time, our customers and potential customers continue to demand an overall lower total cost of design, which can lead to the consolidation of their purchases with one vendor. In order to succeed in this environment, we must successfully meet our customers’ technology requirements and increase the value of our products, while also striving to reduce their overall costs and our own operating costs.

We compete principally on the basis of technology, product quality and features (including ease-of-use), license or usage terms, post-contract customer support, interoperability among products, and price and payment terms. Specifically, we believe the following competitive factors affect our success:

If we fail to successfully manage these competitive factors, fail to successfully balance the conflicting demands for innovative technology and lower overall costs, or fail to address new competitive forces, our business and financial condition will be adversely affected.

If we fail to protect our proprietary technology, our business will be harmed.

Our success depends in part upon protecting our proprietary technology. Our efforts to protect our technology may be costly and unsuccessful. We rely on agreements with customers, employees and others and on intellectual property laws worldwide to protect our proprietary technology. These agreements may be breached, and we may not have adequate remedies for any breach. Additionally, despite our measures to prevent piracy, other parties may attempt to illegally copy or use our products, which could result in lost revenue. Some foreign countries do not currently provide effective legal protection for intellectual property and our ability to prevent the unauthorized use of our products in those countries is therefore limited. Our trade secrets may also be stolen, otherwise become known, or be independently developed by competitors.

We may need to commence litigation or other legal proceedings in order to:

If we do not obtain or maintain appropriate patent, copyright or trade secret protection, for any reason, or cannot fully defend our intellectual property rights in some jurisdictions, our business and

14

Table of Contents

operating results would be harmed. In addition, intellectual property litigation is lengthy, expensive and uncertain and legal fees related to such litigation will increase our operating expenses and may reduce our net income.

Unfavorable tax law changes, changes in our forecasted or actual geographical earnings mix, or an unfavorable government review of our tax returns could adversely affect our effective tax rate and our operating results.

Our operations are subject to income and transaction taxes in the United States and in multiple foreign jurisdictions. A change in the tax law in the jurisdictions in which we do business, including an increase in tax rates or an adverse change in the treatment of an item of income or expense, could result in a material increase in our tax expense. U.S. income taxes and foreign withholding taxes have not been provided for on undistributed earnings for certain of our non-U.S. subsidiaries to the extent such earnings are considered to be indefinitely reinvested in the operations of those subsidiaries. A number of proposals for broad reform of the corporate tax system in the U.S. are under evaluation by various legislative and administrative bodies, but it is not possible to determine accurately the overall impact of such proposals on our effective tax rate at this time.

We have operations in the U.S. and in multiple foreign jurisdictions with a wide range of statutory tax rates. Therefore, any changes in our geographical earnings mix in various tax jurisdictions, including those resulting from transfer pricing adjustments, could materially impact our effective tax rate. Furthermore, we maintain significant deferred tax assets related to federal research credits and foreign tax credits and certain state tax credits. Our ability to use these credits is dependent upon having sufficient future taxable income, including foreign source income in the U.S., as well as sufficient taxable income in certain states. Changes in our forecasts of future income could result in an adjustment to the deferred tax asset and a related charge to earnings that could materially affect our financial results.

The computation of our annual effective tax rate 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 provisions under U.S. GAAP. Income tax expense (benefit) for interim quarters is based on a forecast of our worldwide effective tax rate. This forecast includes forward looking financial projections by jurisdiction as well as a number of other estimates and assumptions. Various items cannot be accurately forecasted and future events may be treated as discrete to the period in which they occur. For these reasons, our worldwide effective tax rate may be materially different than our forecast and fluctuate throughout the year.

Our tax filings are subject to review or audit by the Internal Revenue Service and state, local and foreign taxing authorities. We exercise judgment in determining our worldwide provision for income taxes and, in the ordinary course of our business, there may be transactions and calculations where the ultimate tax determination is uncertain. We are also liable for potential tax liabilities of businesses we acquire. Although we believe our tax estimates are reasonable, we can provide no assurance that any final determination in an audit will not be materially different than the treatment reflected in our historical income tax provisions and accruals. An assessment of additional taxes as a result of an audit could adversely affect our income tax provision and net income in the period or periods for which that determination is made.

We may have to invest more resources in research and development than anticipated, which could increase our operating expenses and negatively affect our operating results.

We devote substantial resources to research and development. New competitors, technological advances in the semiconductor industry or by competitors, our acquisitions, our entry into new markets, or other competitive factors may require us to invest significantly greater resources than we anticipate. If we are required to invest significantly greater resources than anticipated without a

15

Table of Contents

corresponding increase in revenue, our operating results could decline. Additionally, our periodic research and development expenses may be independent of our level of revenue which could negatively impact our financial results. Finally, there can be no guarantee that our research and development investments will result in products that create significant, or even any, revenue.

The global nature of our operations exposes us to increased risks and compliance obligations that may adversely affect our business.

We derive more than half of our revenue from sales outside the United States, and we expect our orders and revenue to continue to depend on sales to customers outside the U.S. In addition, we have expanded our non-U.S. operations significantly in the past several years. This strategy requires us to recruit and retain qualified technical and managerial employees, manage multiple remote locations performing complex software development projects and ensure intellectual property protection outside of the U.S. Our international operations and sales subject us to a number of increased risks, including:

If any of the foreign economies in which we do business deteriorate or if we fail to effectively manage our global operations, our business and results of operations will be harmed.

In addition, our global operations are subject to numerous U.S. and foreign laws and regulations, including those related to anti-corruption, tax, corporate governance, imports and exports, financial and other disclosures, privacy and labor relations. These laws and regulations are complex and may have differing or conflicting legal standards, making compliance difficult and costly. If we violate these laws and regulations we could be subject to fines, penalties or criminal sanctions, and may be prohibited from conducting business in one or more countries. Although we have implemented policies and procedures to ensure compliance with these laws and regulations, there can be no assurance that our employees, contractors or agents will not violate these laws and regulations. Any violation individually or in the aggregate could have a material adverse effect on our operations and financial condition.

Our financial statements are also affected by fluctuations in foreign currency exchange rates. A weakening U.S. dollar relative to other currencies increases expenses of our foreign subsidiaries when they are translated into U.S. dollars in our consolidated statement of operations. Likewise, a strengthening U.S. dollar relative to other currencies, especially the Japanese Yen, reduces revenue of our foreign subsidiaries upon translation and consolidation. Our revenue from Japan has been affected by the devaluation of the Yen in the past year and may continue to fluctuate should the Yen experience significant further volatility. Exchange rates are subject to significant and rapid fluctuations, and therefore we cannot predict the prospective impact of exchange rate fluctuations. Although we engage in foreign currency hedging activity, we may be unable to hedge all of our foreign currency risk, which could have a negative impact on our results of operations.

Liquidity requirements in our U.S. operations may require us to raise cash in uncertain capital markets, which could negatively affect our financial condition.

More than half of our worldwide cash and cash equivalents balance is held by our international subsidiaries in their own accounts outside the United States—approximately 54% as of October 31, 2013. At present, such foreign funds are considered to be indefinitely reinvested abroad to the extent they derive from indefinitely reinvested foreign earnings. We have a credit agreement with several lenders providing for a $150 million term loan facility and a $350 million revolving credit facility, and as of October 31, 2013, we had outstanding debt of $105.0 million under our term loan facility, and no outstanding balance under our revolving credit facility. Should our cash spending needs in the U.S. rise and exceed our existing U.S. balances, available credit under our revolving credit and term loan facilities, and future U.S. cash flows, we may be required to incur additional debt at higher than anticipated interest rates or access other funding sources, which could negatively affect our results of operations, capital structure and the market price of our common stock.

From time to time we are subject to claims that our products infringe on third-party intellectual property rights.

We are from time to time subject to claims alleging our infringement of third-party intellectual property rights, including patent rights. For example, in December 2011, a patent infringement lawsuit was filed against us by Dynetix Design Solutions, Inc., which seeks, among other things, compensatory damages and a permanent injunction. We may also acquire companies that are party to existing infringement claims. For example, EVE, a company we acquired in October 2012, is a party to ongoing patent infringement lawsuits involving Mentor Graphics Corporation. Further information regarding the Dynetix and EVE lawsuits is contained in Part I, Item 3, Legal Proceedings. In addition, under our customer agreements and other license agreements, we agree in many cases to indemnify our customers if our products infringe a third party’s intellectual property rights. Infringement claims can result in costly and time-consuming litigation, require us to enter into royalty arrangements, subject us to damages or injunctions restricting our sale of products, invalidate a patent or family of patents, require us to refund license fees to our customers or to forgo future payments or require us to redesign certain of our products, any one of which could harm our business and operating results.

Product errors or defects could expose us to liability and harm our reputation and we could lose market share.

Software products frequently contain errors or defects, especially when first introduced, when new versions are released or when integrated with technologies developed by acquired companies. Product errors could affect the performance or interoperability of our products, could delay the development or release of new products or new versions of products and could adversely affect market acceptance or perception of our products. In addition, allegations of manufacturability issues resulting from use of our IP products could, even if untrue, adversely affect our reputation and our customers’ willingness to license IP products from us. Any such errors or delays in releasing new products or new versions of products or allegations of unsatisfactory performance could cause us to lose customers, increase our service costs, subject us to liability for damages and divert our resources from other tasks, any one of which could materially and adversely affect our business and operating results.

We may be subject to litigation proceedings that could harm our business.

We may be subject to legal claims or regulatory matters involving stockholder, consumer, employment, competition, and other issues on a global basis. Litigation is subject to inherent uncertainties, and unfavorable rulings could occur. An unfavorable ruling could include monetary damages or, in cases for which injunctive relief is sought, an injunction prohibiting us from manufacturing or selling one or more products. If we were to receive an unfavorable ruling on a matter, our business and results of operations could be materially harmed. Further information regarding

17

material pending lawsuits, other than ordinary routine litigation incidental to our business, is contained in Part I, Item 3, Legal Proceedings.

If we fail to timely recruit and retain senior management and key employees, our business may be harmed.

We depend in large part upon the services of key members of our senior management team to drive our future success. If we were to lose the services of any member of our senior management team, our business could be adversely affected. To be successful, we must also attract and retain key technical, sales and managerial employees, including those who join Synopsys in connection with acquisitions. There are a limited number of qualified EDA and IC design engineers, and competition for these individuals is intense and has increased. Our employees are often recruited aggressively by our competitors and our customers. Any failure to recruit and retain key technical, sales and managerial employees could harm our business, results of operations and financial condition. Additionally, efforts to recruit and retain qualified employees could be costly and negatively impact our operating expenses.

We issue stock options and restricted stock units and maintain employee stock purchase plans as a key component of our overall compensation. We face pressure to limit the use of such equity-based compensation due to its dilutive effect on stockholders. In addition, we are required under GAAP to recognize compensation expense in our results of operations for employee share-based equity compensation under our equity grants and our employee stock purchase plan, which has increased the pressure to limit equity-based compensation. These factors may make it more difficult for us to grant attractive equity-based packages in the future, which could adversely impact and limit our ability to attract and retain key employees.

Our business is subject to evolving corporate governance and public disclosure regulations that have increased both our compliance costs and the risk of noncompliance, which could have an adverse effect on our stock price.

We are subject to changing rules and regulations promulgated by a number of governmental and self-regulatory organizations, including the SEC, the NASDAQ Stock Market, and the FASB. These rules and regulations continue to evolve in scope and complexity and many new requirements have been created in response to laws enacted by Congress, making compliance more difficult and uncertain. For example, our efforts to comply with the Dodd-Frank Wall Street Reform and Consumer Protection Act and other new regulations have resulted in, and are likely to continue to result in, increased general and administrative expenses and a diversion of management time and attention from revenue-generating activities to compliance activities.

There are inherent limitations on the effectiveness of our controls and compliance programs.

Regardless of how well designed and operated it is, a control system can provide only reasonable assurance that its 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. Moreover, although we have implemented compliance programs and compliance training for employees, such measures may not prevent our employees, contractors or agents from breaching or circumventing our policies or violating applicable laws and regulations. Failure of our control systems and compliance programs to prevent error, fraud or violations of law could have a material adverse impact on our business.

Our investment portfolio may be impaired by the deterioration of capital markets.

Our cash equivalent portfolio currently consists of tax-exempt money market mutual funds, taxable money market mutual funds and bank deposits. In general, our investment portfolio may carry both

18

Table of Contents

interest rate risk and credit risk. We may hold fixed rate debt securities that can have their market value adversely impacted due to a credit downgrade or a rise in interest rates, or floating rate securities that may produce less income than expected if interest rates fall or a credit downgrade occurs. As a result of current adverse financial market conditions, capital pressures on certain banks, especially in Europe, and the continuing low interest rate environment, some of our financial instruments may become impaired. Further, while the U.S. government has raised the federal “debt ceiling” to allow it to borrow funds through February 7, 2014, if the debt ceiling is not raised beyond that date, the U.S. government may default, which could impact the liquidity of our investment funds.

Our future investment income may fall short of expectations due to changes in interest rates or if the decline in fair value of investments held by us is judged to be other-than-temporary.

Security breaches could compromise sensitive information belonging to us or our customers and could harm our business and reputation.

We store sensitive data, including intellectual property, our proprietary business information and that of our customers, and confidential employee information, in our data centers and on our networks. Despite our security measures, our information technology and infrastructure may be vulnerable to attacks by hackers or breached due to employee error, malfeasance or other disruptions that could result in unauthorized disclosure or loss of sensitive information. Because the techniques used to obtain unauthorized access to networks, or to sabotage systems, change frequently and generally are not recognized until launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. Furthermore, in the operation of our business we also use third-party vendors that store certain sensitive data, including confidential information about our employees, and these third parties are subject to their own cybersecurity threats. Any security breach of our own or a third-party vendor’s systems could cause us to be non-compliant with applicable laws or regulations, subject us to legal claims or proceedings, disrupt our operations, damage our reputation, and cause a loss of confidence in our products and services, any of which could adversely affect our business.

In preparing our financial statements we make certain assumptions, judgments and estimates that affect amounts reported in our consolidated financial statements, which, if not accurate, may significantly impact our financial results.

We make assumptions, judgments and estimates for a number of items, including the fair value of financial instruments, goodwill, long-lived assets and other intangible assets, the realizability of deferred tax assets, the recognition of revenue and the fair value of stock awards. We also make assumptions, judgments and estimates in determining the accruals for employee-related liabilities, including commissions and variable compensation, and in determining the accruals for uncertain tax positions, allowances for doubtful accounts, and legal contingencies. These assumptions, judgments and estimates are drawn from historical experience and various other factors that we believe are reasonable under the circumstances as of the date of the consolidated financial statements. Actual results could differ materially from our estimates, and such differences could significantly impact our financial results.

Catastrophic events may disrupt our business and harm our operating results.

Due to the global nature of our business, our operating results may be negatively impacted by catastrophic events throughout the world. We rely on a global network of infrastructure applications, enterprise applications and technology systems for our development, marketing, operational, support and sales activities. A disruption or failure of these systems in the event of a major earthquake, fire, telecommunications failure, cybersecurity attack, terrorist attack, or other catastrophic event could cause system interruptions, delays in our product development and loss of critical data and could prevent us from fulfilling our customers’ orders. Moreover, our corporate headquarters, a significant

19

Table of Contents

portion of our research and development activities, our data centers, and certain other critical business operations are located in California, near major earthquake faults. A catastrophic event that results in the destruction or disruption of our data centers or our critical business or information technology systems would severely affect our ability to conduct normal business operations and, as a result, our operating results would be adversely affected.

None.

Our principal offices are located in four adjacent buildings in Mountain View, California, which together provide approximately 400,000 square feet of available space. This space is leased through February 2015. We also lease approximately 237,000 square feet of space in three separate buildings in Sunnyvale, California, with lease expiration dates ranging from September 2019 to October 2019. We own one building in Sunnyvale, California with approximately 120,000 square feet of space. These buildings in Mountain View and Sunnyvale are used for research and development, sales and support, marketing, and administrative activities.

In addition, in October 2011, we agreed to lease two office buildings to be constructed in Mountain View, California. Once construction is complete, the buildings together will provide approximately 341,000 square feet. The lease of such premises begins upon the later of March 1, 2015 or six months after construction is substantially completed. We may terminate the lease prior to such time if certain conditions occur.

We currently lease 22 other offices throughout the United States, and own 2 office buildings in Oregon, one of which is leased to a tenant. These offices are used primarily for sales and support activities.

International Facilities

We lease additional space for sales, service and research and development activities in approximately 27 countries throughout the world, including 25,000 square feet in Dublin, Ireland for our international headquarters, as well as significant sites in Yerevan, Armenia, Bangalore, India and Shanghai, China. In addition we own two buildings in Hsinchu, Taiwan with approximately 211,000 square feet of combined space.

We believe that our existing facilities, including both owned and leased properties, are in good condition and suitable for the current conduct of our business.

We are subject to routine legal proceedings, as well as demands, claims and threatened litigation that arise in the normal course of our business. The ultimate outcome of any litigation is uncertain and unfavorable outcomes could have a negative impact on our results of operations and financial condition. Regardless of outcome, litigation can have an adverse impact on Synopsys because of the defense costs, diversion of management resources and other factors.

On December 5, 2011, plaintiff Dynetix Design Solutions, Inc. (Dynetix) filed a patent infringement lawsuit against Synopsys in federal district court in the Northern District of California, alleging, among other things, that our VCS functional verification tool, and more specifically our VCS multicore technology, infringed Dynetix’s United States Patent No. 6,466,898. The lawsuit seeks, among other things, compensatory damages and a permanent injunction. Synopsys asserted declaratory relief

20

Table of Contents

counterclaims and patent infringement counterclaims against Dynetix. As a result of certain pre-trial rulings in Synopsys’ favor, the parties stipulated to entry of judgment in Synopsys’ favor on Dynetix’s patent infringement claim and on Synopsys’ counterclaim for a declaration of non-infringement. The court entered the stipulated judgment on September 16, 2013. Dynetix has appealed from the judgment.

We acquired Emulation & Verification Engineering S.A. (EVE) on October 4, 2012. At the time of the acquisition, EVE and EVE-USA, Inc. (collectively, the EVE Parties) were defendants in three patent infringement lawsuits filed by Mentor Graphics Corporation (Mentor). Mentor filed suit against the EVE Parties in federal district court in the District of Oregon on August 16, 2010 alleging that EVE’s ZeBu products infringe Mentor’s United States Patent No. 6,876,962. Mentor filed an additional suit in federal district court in the District of Oregon on August 17, 2012 alleging that EVE’s ZeBu products infringe Mentor’s United States Patent No. 6,947,882. Both cases seek compensatory damages and a permanent injunction. Mentor also filed a patent infringement lawsuit against Nihon EVE K.K. in Tokyo District Court in 2010 alleging that EVE’s ZeBu series of products infringes Mentor’s Japanese Patent No. P3,588,324. This case seeks compensatory damages, a permanent injunction and destruction of inventory.

On September 27, 2012, Synopsys and the EVE Parties filed an action for declaratory relief against Mentor in federal district court in the Northern District of California, seeking a determination that Mentor’s United States Patents Nos. 6,009,531; 5,649,176 and 6,240,376, which were the subject of a patent infringement lawsuit filed by Mentor against EVE in 2006 and settled in the same year, are invalid and not infringed by EVE’s products, and that Mentor is without right or authority to threaten or maintain suit against the plaintiffs on such patents. Mentor has asserted patent infringement counterclaims in this action based on the same three patents and is seeking compensatory damages and a permanent injunction. In April 2013, this action was transferred to the federal district court in Oregon and consolidated with the two Mentor lawsuits in that district (the Oregon Action).

In the Oregon Action, Synopsys and the EVE Parties have further asserted patent infringement counterclaims against Mentor based on Synopsys’ United States Patents Nos. 6,132,109 and 7,069,526, seeking compensatory damages and a permanent injunction.

On September 26, 2012, Synopsys filed two inter partes review requests with the U.S. Patent and Trademark Office (the PTO) challenging the validity of Mentor’s ‘376 and ‘882 patents. The PTO granted review of the ‘376 patent and denied review of the ‘882 patent.

On December 21, 2012, Synopsys filed an action for patent infringement against Mentor in federal district court in the Northern District of California, alleging that Mentor’s Veloce products infringe Synopsys’ United States Patents Nos. 5,748,488, 5,530,841, 5,680,318 and 6,836,420. This case seeks compensatory damages and a permanent injunction.

Stock Repurchase Program

Our Board of Directors (Board) approved a stock repurchase program in 2002 pursuant to which we were authorized to purchase up to $500.0 million of our common stock, and has periodically replenished the stock repurchase program to such amount. We repurchase shares to offset dilution caused by ongoing stock issuances from existing equity plans for equity compensation awards and issuances related to acquisitions, and when management believes it is a good use of cash. Repurchases are transacted in accordance with Rule 10b-18 of the Securities Exchange Act of 1934 (Exchange Act) and may be made through any means including, but not limited to, open market purchases, plans executed under Rule 10b5-1(c) of the Exchange Act and structured transactions. As of October 31, 2013, $127.4 million remained available for further repurchases under the program. Our Board replenished the stock repurchase program up to $500.0 million on December 3, 2013.

The table below sets forth information regarding our repurchases of our common stock during the three months ended October 31, 2013.

See Note 9 of Notes to Consolidated Financial Statements for further information regarding our stock repurchase program.

Overview

The following summary of our financial condition and results of operations is qualified in its entirety by the more complete discussion contained in this Item 7 and by the risk factors set forth in Item 1A of this Annual Report. Please also see the cautionary language at the beginning of Part I of this Annual Report regarding forward-looking statements.

Business Summary

Synopsys is a global leader in providing software, intellectual property and services used to design integrated circuits and electronic systems. We supply the electronic design automation (EDA) software that engineers use to design, create prototypes for and test integrated circuits, also known as chips. We also supply software and hardware used to develop the systems that incorporate integrated circuits and the software that runs on those integrated circuits. Our intellectual property (IP) products are pre-designed circuits that engineers use as components of larger chip designs rather than redesigning those circuits themselves. To complement these product offerings, we provide technical services to support our solutions and we help our customers develop chips and electronic systems.

Our customers are generally semiconductor and electronics systems companies. Our solutions help them overcome the challenge of developing increasingly advanced electronics products while reducing their design and manufacturing costs. While our products are an important part of our customers’ development process, our customers’ research and development budget and spending decisions may be affected by their business outlook and their willingness to invest in new and increasingly complex chip designs.

Despite global economic uncertainty, we have maintained profitability and positive cash flow on an annual basis in recent years. We achieved these results not only because of our solid execution, leading technology and strong customer relationships, but also because of our time-based revenue business model. Under this model, a substantial majority of our customers pay for their licenses over time and we typically recognize this revenue over the life of the contract, which averages approximately three years. Time-based revenue, which consists of time-based license, maintenance and service revenue, generally represents approximately 90% of our total revenue. The revenue we recognize in a particular period generally results from selling efforts in prior periods rather than the current period. Due to our business model, decreases as well as increases in customer spending do not immediately affect our revenues in a significant way.

The global economy continues to exhibit some uncertainty, with 2013 being characterized by gradual, and uneven, economic recovery. Nonetheless, our business outlook remains strong based on continued demand for our products, our business model, strong financials, diligent expense management, and acquisition strategy. In addition, consumer demand for electronics has been solid, particularly the demand for mobile devices. Through our recent acquisitions, we have enhanced our technology and expanded our product portfolio and our total addressable market, especially in IP and system-level solutions, which we believe will help drive revenue growth. We believe that the

combination of our solid financials, leading technology and strong customer relationships will help us to continue to successfully execute our strategies.

Fiscal Year End

Our fiscal year generally ends on the Saturday nearest to October 31 and consists of 52 weeks, with the exception that approximately every five years, we have a 53-week year.

Fiscal 2013 was a 52-week year ending on November 2, 2013. Fiscal 2012 and fiscal 2011 were 53-week and 52-week years, respectively, ending on November 3, 2012 and October 29, 2011, respectively. The extra week in fiscal 2012 resulted in approximately $26 million of additional revenue, related primarily to time-based licenses, and approximately $16 million of additional expenses.

For presentation purposes, this Form 10-K refers to October 31 as the end of our fiscal year.

Fiscal 2013 Financial Performance Summary

In fiscal 2013, we experienced overall growth in our business, including from our acquisitions, which was reflected in a 36% increase in our net income compared to last year. Compared to fiscal 2012:

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial results under the heading “Results of Operations” below are based on our audited results of operations, which we have prepared in accordance with GAAP. In preparing these financial statements, we make assumptions, judgments and estimates that can affect the reported amounts of assets, liabilities, revenues and expenses and net income. On an on-going basis, we evaluate our estimates based on historical experience and various other assumptions we believe are reasonable under the circumstances. Our actual results may differ from these estimates. For further information on our significant accounting policies, see Note 2 of Notes to Consolidated Financial Statements.

The accounting policies that most frequently require us to make assumptions, judgments and estimates, and therefore are critical to understanding our results of operations, are:

Revenue Recognition

Software license revenue consists of fees associated with the licensing of our software. Maintenance and service revenue consists of maintenance fees associated with perpetual and term licenses and professional services fees. Hardware revenue consists of FPGA-based emulation and prototyping products.

26

Table of Contents

With respect to software licenses, we utilize three license types:

For the three software license types, we recognize revenue as follows:

We also enter into arrangements in which portions of revenue are contingent upon the occurrence of uncertain future events, for example, royalty arrangements. We refer to this revenue as “contingent revenue.” Contingent revenue is recognized if and when the applicable event occurs. Such revenue is reported as “time-based license revenue” in the consolidated statements of operations. These arrangements are not material to our total revenue.

We recognize revenue from sales of hardware and perpetual licenses to IP and system-level products in full upon shipment if all other revenue recognition criteria are met. Revenue attributable to these sales is reported as “upfront license revenue” in the consolidated statements of operations and is not material to our total revenue.

We infrequently enter into multiple-element arrangements that contain both software and non-software deliverables such as hardware. We have determined that the software and non-software

27

Table of Contents

deliverables in our contracts are separate units of accounting. We recognize revenue for the separate units of accounting when all revenue recognition criteria are met. Revenue allocated to hardware units of accounting is recognized upon shipment when all other revenue recognition criteria are met. Revenue allocated to software units of accounting is recognized depending on the software license type (TSL, term license or perpetual license). Such arrangements have not had a material effect on our consolidated financial statements and are not expected to have a material effect in future periods.

We recognize revenue from maintenance fees ratably over the maintenance period to the extent cash has been received or fees become due and payable, and recognize revenue from professional services and training fees as such services are performed and accepted by the customer. Revenue attributable to maintenance, professional services and training is reported as “maintenance and service revenue” in the consolidated statements of operations.

We also enter into arrangements to deliver software products, either alone or together with other products or services that require significant modification, or customization of the software. We account for such arrangements using the percentage of completion method as we have the ability to make reasonably dependable estimates that relate to the extent of progress toward completion, contract revenues and costs. We measure the progress towards completion using the labor hours incurred to complete the project. Revenue attributable to these arrangements is reported as maintenance and service revenue in the consolidated statements of operations.

We determine the fair value of each element in multiple element software arrangements that only contain software and software related deliverables based on vendor-specific objective evidence (VSOE). We limit our assessment of VSOE of fair value for each element to the price charged when such element is sold separately. We have analyzed all of the elements included in our multiple-element software arrangements and have determined that we have sufficient VSOE to allocate revenue to the maintenance components of our perpetual and term license products and to professional services. Accordingly, assuming all other revenue recognition criteria are met, we recognize license revenue from perpetual and term licenses upon delivery using the residual method, recognize revenue from maintenance ratably over the maintenance term, and recognize revenue from professional services as services are performed and accepted by the customer. We recognize revenue from TSLs ratably over the term of the license, assuming all other revenue recognition criteria are met, since there is not sufficient VSOE to allocate the TSL fee between license and maintenance services.

We make significant judgments related to revenue recognition. Specifically, in connection with each transaction involving our products, we must evaluate whether: (1) persuasive evidence of an arrangement exists, (2) delivery of software or services has occurred, (3) the fee for such software or services is fixed or determinable, and (4) collectability of the full license or service fee is probable. All four of these criteria must be met in order for us to recognize revenue with respect to a particular arrangement. We apply these revenue recognition criteria as follows:

28

Table of Contents

Valuation of Stock Compensation

Stock compensation expense is measured on the grant date based on the fair value of the award and is recognized as expense over the vesting period in accordance with ASC 718, Stock Compensation. We use the Black-Scholes option-pricing model to determine the fair value of stock options and employee stock purchase plan awards. The Black-Scholes option-pricing model incorporates various subjective assumptions including expected volatility, expected term and risk-free interest rates. We estimate the expected volatility by a combination of implied volatility for publicly traded options of our stock with a term of six months or longer and the historical stock price volatility over the estimated expected term of our stock awards. We determine the expected term of our stock awards based on historical experience. In addition, judgment is required in estimating the forfeiture rate on stock awards. We calculate the expected forfeiture rate based on average historical trends. These input factors are subjective and are determined using management’s judgment. If a difference arises between the assumptions used in determining stock compensation cost and the actual factors which become known over time, we may change the input factors used in determining future stock compensation costs. Any such changes could materially impact our results of operations in the period in which the changes are made and in periods thereafter.

Valuation of Intangible Assets

We evaluate our intangible assets for indications of impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Intangible assets consist of purchased technology, contract rights intangibles, customer-relationships, trademarks and trade names, covenants not to compete, capitalized software development, and in-process research and development. Factors that could trigger an impairment review include significant under-performance relative to expected historical or projected future operating results, significant changes in the manner of our use of the acquired assets or the strategy for our overall business or significant negative industry or economic trends. If this evaluation indicates that the value of the intangible asset may be impaired, we make an assessment of the recoverability of the net carrying value of the asset over its remaining useful life. If this assessment indicates that the intangible asset is not recoverable, based on the estimated undiscounted future cash flows of the technology over the remaining useful life, we reduce

29

Table of Contents

the net carrying value of the related intangible asset to fair value. Any such impairment charge could be significant and could have a material adverse effect on our reported financial results. We did not record any impairment charges on our intangible assets during fiscal 2013, 2012 or 2011.

Income Taxes

Our tax provisions are calculated using estimates in accordance with ASC 740, Income Taxes. Our estimates and assumptions may differ from the actual results as reflected in our income tax returns and we record the required adjustments when they are identified or resolved.

We recognize deferred tax assets and liabilities for the temporary differences between the book and tax bases of assets and liabilities using enacted tax rates in effect for the year in which we expect the differences to reverse, and for tax loss and credit carryovers. We record a valuation allowance to reduce the deferred tax assets to the amount that is more likely than not to be realized. In evaluating our ability to utilize our deferred tax assets, we consider all available positive and negative evidence, including our past operating results, our forecast of future taxable income on a jurisdiction by jurisdiction basis, as well as feasible and prudent tax planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates we are using to manage the underlying businesses. We believe that the net deferred tax assets of approximately $307.2 million that are recorded on our balance sheet as of October 31, 2013 will ultimately be realized. However, if we determine in the future that it is more likely than not we will not be able to realize a portion or the full amount of deferred tax assets, we would record an adjustment to the deferred tax asset valuation allowance as a charge to earnings in the period such determination is made.

We apply a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining whether it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement.

The calculation of tax liabilities involves the inherent uncertainty associated with the application of complex tax laws. We are also subject to examination by various taxing authorities. We believe we have adequately provided in our financial statements for potential additional taxes. If we ultimately determine that these amounts are not owed, we would reverse the liability and recognize the tax benefit in the period in which we determine that the liability is no longer necessary. If an ultimate tax assessment exceeds our estimate of tax liabilities, we would record an additional charge to earnings.

Results of Operations

Revenue Background

We generate our revenue from the sale of software licenses, maintenance and professional services and to a small extent, hardware products. Under current accounting rules and policies, we recognize revenue from orders we receive for software licenses, services and hardware products at varying times. In most instances, we recognize revenue on a TSL software license order over the license term and on a term or perpetual software license order in the quarter in which the license is delivered. The average license term of the TSLs and term licenses we entered into in fiscal 2013, 2012, and 2011 was 3.6 years, 2.7 years and 2.8 years, respectively. Revenue on contracts requiring significant modification or development is accounted for using the percentage of completion method over the period of the development. Revenue on hardware product orders is generally recognized in full at the time the product is shipped. Contingent revenue is recognized if and when the applicable event occurs.

30

Table of Contents

Revenue on maintenance orders is recognized ratably over the maintenance period (normally one year). Revenue on professional services orders is generally recognized after services are performed and accepted by the customer.

Our revenue in any period is equal to the sum of our time-based license, upfront license, maintenance and professional services for the period. We derive time-based license revenue largely from TSL orders received and delivered in prior quarters and to a smaller extent due to contracts in which revenue is recognized as customer installments become due and payable and from contingent revenue arrangements. We derive upfront license revenue directly from term and perpetual license and hardware product orders mostly booked and shipped during the period. We derive maintenance revenue largely from maintenance orders received in prior periods since our maintenance orders generally yield revenue ratably over a term of one year. We also derive professional services revenue primarily from orders received in prior quarters, since we recognize revenue from professional services as those services are delivered and accepted or on percentage of completion for arrangements requiring significant modification of our software, and not when they are booked. Our license revenue is sensitive to the mix of TSLs and perpetual or term licenses delivered during a reporting period. A TSL order typically yields lower current quarter revenue but contributes to revenue in future periods. For example, a $120,000 order for a three-year TSL delivered on the last day of a quarter typically generates no revenue in that quarter, but $10,000 in each of the twelve succeeding quarters. Conversely, a $120,000 order for perpetual and term licenses with greater than 75% of the license fee due within one year from shipment typically generates $120,000 in revenue in the quarter the product is delivered, but no future revenue. Additionally, revenue in a particular quarter may also be impacted by perpetual and term licenses in which less than 75% of the license fees and 100% of the maintenance fees are payable within one year from shipment as the related revenue will be recognized as revenue in the period when customer payments become due and payable.

Our customer arrangements are complex, involving hundreds of products and various license rights, and our customers bargain with us over many aspects of these arrangements. For example, they often demand a broader portfolio of solutions, support and services and seek more favorable terms such as expanded license usage, future purchase rights and other unique rights at an overall lower total cost. No single factor typically drives our customers’ buying decisions, and we compete on all fronts to serve customers in a highly competitive EDA market. Customers generally negotiate the total value of the arrangement rather than just unit pricing or volumes.

Total Revenue

The overall growth of our business has been the primary driver of the increase in our revenue. Our revenues are subject to fluctuations, primarily due to customer requirements, including payment terms and the timing and value of contract renewals.

The sequential increase in total revenue from fiscal 2011 through fiscal 2013 was due to our organic growth and revenues from acquired companies. The increases were primarily in time-based license revenue. Fiscal 2012 had approximately $26 million of additional revenue due to the additional week in that fiscal year.

31

Table of Contents

Time-Based License Revenue

The increase in time-based license revenue for fiscal 2013 compared to fiscal 2012 was primarily attributable to increases in TSL license revenue from arrangements booked in prior periods, including those from acquisitions in fiscal 2012 and particularly in the fourth quarter of fiscal 2012, and to a lesser extent, due to other time-based arrangements. The increase was partially offset by the impact of the additional week in fiscal 2012.

The increase in time-based license revenue for fiscal 2012 compared to fiscal 2011 was primarily attributable to increases in TSL license revenue from arrangements booked in prior periods and from the contracts acquired through fiscal 2012 acquisitions and, to a lesser extent, due to higher contingent revenue, product sales, the impact of the additional week in fiscal 2012 and other time-based arrangements.

Upfront License Revenue

Changes in upfront license revenue are generally attributable to normal fluctuations in customer requirements, which can drive the amount of upfront orders and revenue in any particular period.

The increase in upfront license revenue for fiscal 2013 compared to fiscal 2012 was primarily attributable to the increase in sales of our hardware products and perpetual licenses to IP and system-level products, including those derived from our acquisitions in the fourth quarter of fiscal 2012.

The increase in upfront license revenue for fiscal 2012 compared to fiscal 2011 was primarily attributable to the increase in sales of our hardware products and perpetual licenses to IP and system-level products.

As our sales of hardware and perpetual licenses to IP and system-level products continue to grow, we expect upfront license revenue to increase as a percentage of total revenue, but remain consistent with our business model in which approximately 90% of our total revenue consists of time-based revenue.

Maintenance and Service Revenue

32

Table of Contents

Changes in maintenance revenue are generally attributable to the timing of renewals and the type of contracts renewed with the associated maintenance. Maintenance revenue was relatively flat during fiscal 2013, 2012 and 2011.

The sequential increase in professional services and other revenue from fiscal 2011 through fiscal 2013 was primarily due to an increase in IP consulting services.

Cost of Revenue and Operating Expenses

Our expenses are generally impacted by changes in personnel-related costs including salaries, benefits, stock compensation and variable compensation, changes in amortization and changes in selling and marketing expenses. The increase in our expenses compared to prior fiscal years was primarily due to an increase in personnel-related costs, driven by increased headcount from our acquisitions and related fixed charges including facilities, amortization of intangible assets, and depreciation. The increases in our expenses were partially offset by the extra week of expenses in fiscal 2012 of $16 million. We allocate certain human resource programs, information technology and facility expenses among our functional income statement categories based on headcount within each functional area. Annually, or upon a significant change in headcount (such as a workforce reduction, realignment or acquisition) or other factors, management reviews the allocation methodology and expenses included in the allocation pool. Consequently, fluctuations in these drivers impact the amounts allocated to each functional area.

Foreign currency fluctuations, net of hedging, did not have a significant impact on expenses during fiscal 2013 as compared to fiscal 2012, or fiscal 2012 as compared to fiscal 2011. See Note 5 of Notes to Consolidated Financial Statements for details on our foreign exchange hedging programs.

Cost of Revenue

We divide cost of revenue into three categories: cost of license revenue, cost of maintenance and service revenue, and amortization of intangible assets. We segregate expenses directly associated with consulting and training services from cost of license revenue associated with internal functions providing license delivery and post-customer contract support services. We then allocate these group

33

Table of Contents

costs between cost of license revenue and cost of maintenance and service revenue based on license and maintenance and service revenue reported.

Cost of license revenue. Cost of license revenue includes costs related to products sold and software licensed, allocated operating costs related to product support and distribution costs, royalties paid to third party vendors, and the amortization of capitalized research and development costs associated with software products which have reached technological feasibility.

Cost of maintenance and service revenue. Cost of maintenance and service revenue includes operating costs related to maintaining the infrastructure necessary to operate our services and training organization, and costs associated with the delivery of our consulting services, such as, hotline and on-site support, production services and documentation of maintenance updates.

Amortization of intangible assets. Amortization of intangible assets, which is recorded to cost of revenue and operating expenses, includes the amortization of certain contract rights and the amortization of core/developed technology, trademarks, trade names, customer relationships, and covenants not to compete related to acquisitions.

Cost of revenue increased by $60.9 million or 16% in fiscal 2013 compared to fiscal 2012 due to increases of $23.0 million in amortization of intangible assets and $17.7 million in personnel-related costs, primarily as a result of acquisitions in fiscal 2012, particularly in the fourth quarter of fiscal 2012, and $25.9 million in product costs primarily due to product sales. The increase in cost of revenue was partially offset by an additional week of expenses of approximately $2.2 million in fiscal 2012 and a $1.3 million reduction in acquisition-related costs compared to fiscal 2012.

Cost of revenue increased by $52.2 million or 15% in fiscal 2012 compared to fiscal 2011. The increase was primarily due to increases of $26.5 million in amortization of intangible assets, $19.0 million in personnel-related costs as a result of fiscal 2012 acquisitions and the impact of one extra week of costs of approximately $2.2 million in fiscal 2012.

Operating Expenses

Research and Development

The increase in research and development expense in fiscal 2013 compared to fiscal 2012 was primarily due to increases of $76.1 million in personnel-related costs and $11.0 million in functionally allocated expenses, as a result of headcount increases primarily from our acquisitions in fiscal 2012, particularly in the fourth quarter of fiscal 2012, and $8.6 million in consulting costs. The increase in research and development expenses was partially offset by an additional week of expenses of approximately $7.5 million in fiscal 2012 and a $6.3 million reduction in acquisition-related costs compared to fiscal 2012.

The increase in research and development expense in fiscal 2012 compared to fiscal 2011 was primarily due to increases of $61.0 million in personnel-related costs as a result of headcount increases primarily from our acquisitions, $11.1 million in functionally allocated expenses as a result of headcount increases from our current year acquisitions, $7.9 million in costs related to acquisitions, and one extra week of costs of approximately $7.5 million in fiscal 2012 compared with fiscal 2011.

34

Table of Contents

Sales and Marketing

Changes in commissions and other variable compensation are generally attributable to the volume of contracts and timing of shipments based on contract requirements.

The increase in sales and marketing expense for fiscal 2013 compared with fiscal 2012 was due to increases in personnel-related costs of $15.9 million primarily driven by headcount increases, $2.0 million in marketing activities, and $1.4 million in maintenance. The increase in sales and marketing expenses was partially offset by an additional week of expenses of approximately $4.9 million in fiscal 2012 and a $5.2 million reduction in acquisition-related costs compared to fiscal 2012.

The increase in sales and marketing expense for fiscal 2012 compared with fiscal 2011 was due to increases in personnel-related costs of $25.6 million primarily driven by headcount increases from our acquisitions, $11.2 million in variable compensation due to higher shipments, $8.9 million in costs related to acquisitions, and one extra week of costs of approximately $4.9 million in fiscal 2012 compared with fiscal 2011.

General and Administrative

The decrease in general and administrative expenses was due to a decrease in acquisition-related costs of $25.4 million compared to fiscal 2012 and higher allocation of $7.7 million in expenses to other functions (cost of revenue, research and development, and sales and marketing) in fiscal 2013 as headcount growth in those functions, primarily driven by acquisitions, resulted in an increase in the pool of expenses to be allocated. The decrease in general and administrative expense was partially offset by increases of $15.2 million in professional service costs, $5.4 million in facilities and depreciation expenses, primarily due to our acquisitions, and $2.2 million in personnel-related costs as a result of headcount increases primarily from our acquisitions.

The increase in general and administrative expense for fiscal 2012 compared with fiscal 2011 was primarily due to increases of $15.9 million in personnel-related costs as a result of headcount increases primarily from our acquisitions, $24.5 million in costs related to acquisitions, $6.8 million in facility expenses, $5.8 million in depreciation and maintenance expenses and one extra week of costs of approximately $1.6 million in fiscal 2012 compared with fiscal 2011. The increases were partially offset by a higher allocation of $18.0 million in expenses to other functions in fiscal 2012 compared to fiscal 2011, as a result of increased expenses in the allocation pool.

Change in Fair Value of Deferred Compensation

The income or loss arising from the change in fair value of our non-qualified deferred compensation plan obligation is recorded in cost of sales and each functional operating expense, with the offsetting change in the fair value of the related assets recorded in other income (expense), net. These assets are classified as trading securities. There is no overall impact to our net income from the income or loss of our deferred compensation plan obligation and asset.

35

Table of Contents

Acquired In-Process Research and Development

In-process research and development (IPR&D) costs relate to in-process technologies acquired in acquisitions. The value assigned to IPR&D is determined by considering the importance of each project to our overall development plan, estimating costs to develop the IPR&D into commercially viable products, estimating the resulting net cash flows from such projects when completed and discounting the net cash flows back to their present value. The utilized discount rate is our weighted average cost of capital, taking into account the inherent uncertainties in future revenue estimates and the profitability of such technology, the successful development of the IPR&D, its useful life and the uncertainty of technological advances, all of which are unknown at the time of determination.

Upon completion of development, the underlying intangible asset is amortized over its estimated useful life and recorded in cost of revenue. IPR&D projects acquired are anticipated to be completed over a period of one to three years from the date of the acquisition. See Note 4 of Notes to Consolidated Financial Statements.

Amortization of Intangible Assets

Amortization of intangible assets includes the amortization of contract rights and the amortization of core/developed technology, trademarks, trade names, customer relationships, covenants not to compete, and in-process research and development related to acquisitions completed in prior years. Amortization expense is included in the consolidated statements of operations as follows:

Amortization of capitalized software development costs is not presented in the above table and is included in cost of license revenue in the consolidated statements of operations.

The increases in amortization of intangible assets from fiscal 2011 through 2013 were primarily due to the amortization of intangible assets from acquisitions partially offset by certain intangible assets becoming fully amortized. See Note 4 of Notes to Consolidated Financial Statements for a schedule of future amortization amounts, which is incorporated by reference here.

Impairment of Intangible Assets. We did not record any impairment charges to our intangible assets during fiscal 2013, 2012, or 2011.

Other Income (Expense), Net

36

Table of Contents

The net increase in other income (expense) in fiscal 2013 as compared to fiscal 2012 was primarily due to an increase in market value of the assets related to our deferred compensation plan, and an increase in gains in our foreign currency contracts, partially offset by lower interest expense due to a decrease in principal payment on a term loan.

The net increase in other income (expense) in fiscal 2012 as compared to fiscal 2011 was primarily due to an increase in gain on assets related to our deferred compensation plan, and an increase in premiums on foreign currency contracts included in other income (expense), net, partially offset by higher interest expense due to a term loan that we entered into in fiscal 2012.

Income Taxes

Our effective tax rate for fiscal 2013 included tax benefits from the reinstatement of the U.S. federal research tax credit of approximately $19.0 million, reversal of deferred taxes resulting from the merger of a foreign affiliate of $6.8 million, and settlement with the Internal Revenue Service (IRS) of certain issues related to fiscal 2012 of $1.1 million. The reinstatement of the research tax credit resulted in an additional tax credit for ten months of fiscal 2012 as well as a full year credit for fiscal 2013, compared to only two months of credit in fiscal 2012 as a result of the expiration of the credit on December 31, 2011. Our effective tax rate for fiscal 2012 included tax benefits from settlements with the IRS of $15.9 million (for fiscal years 2010 through 2011), with Taiwan tax authorities of $14.7 million (net tax benefit resulting from the 2008 settlement being applied to other open fiscal years), and with Hungarian tax authorities of $6.3 million (for fiscal years 2006 through 2010). For further discussion of the provision for income taxes and settlements, see Note 11 of the Notes to Consolidated Financial Statements.

Liquidity and Capital Resources

Our sources of cash and cash equivalents are funds generated from our business operations and funds that may be drawn down under our credit facility.

As of October 31, 2013, we held an aggregate of $468.4 million in cash and cash equivalents in the United States and an aggregate of $554.0 million in our foreign subsidiaries. Funds held in our foreign subsidiaries are generated from revenue outside North America. At present, such foreign funds are considered to be indefinitely reinvested in foreign countries to the extent of indefinitely reinvested foreign earnings. In the event funds from foreign operations are needed to fund cash needs in the United States and if U.S. taxes have not already been previously accrued, we would be required to accrue and pay additional U.S. taxes in order to repatriate these funds.

The following sections discuss changes in our balance sheet and cash flows, and other commitments on our liquidity and capital resources during fiscal 2013.

Cash and cash equivalents

Our cash generated from operating activities was $496.7 million in fiscal 2013.

Other cash activities were (1) share repurchases of $145.0 million offset by proceeds from employee stock plans of $131.9 million, (2) purchases of property and equipment of $65.5 million offset by proceeds from sale of property and equipment of $2.0 million, (3) acquisition of the non-controlling interest in SpringSoft, Inc. for $44.0 million, and (4) repayment of a term loan of $30.0 million.
