PRODUCT DEVELOPMENT AND INTRODUCTION

The technology industry is characterized by rapid technological change in computer hardware, operating systems, and software. In addition, our customers’ requirements and preferences rapidly evolve, as do their expectations of the performance of our software. To keep pace with these changes, we maintain a vigorous program of new product development to address demands in the marketplace for our products.

The software industry is undergoing a transition from the personal computer to cloud, social, and mobile computing. In fiscal 2015, we continued to successfully implement a strategic transition of our business model announced in fiscal 2014. We accelerated our move to the cloud and expanded our flexible product license offerings. We introduced Desktop Subscription (formerly known as rental) for a broader range of our product portfolio, expanded our new token-based licensing program to more enterprise customers, and continued to expand our industry leading cloud based offerings. These offerings are designed to give our customers even more value and flexibility to use our products, and also to attract new types of customers, such as project-based users and small businesses that have more variable needs. Further, to support our transition, we have discontinued licensing upgrades effective March 6, 2015 and, on February 4, 2015, we also announced that new commercial seats of most standalone software products will be available only by desktop subscription beginning February 1, 2016. Collectively, these measures helped increase many of our performance metrics including billings, deferred revenue, and subscriptions, which will result in more predictable and ratable revenue over time.

We dedicate considerable technical and financial resources to research and development to further enhance our existing products and to create new products and technologies. For example, in fiscal 2015, we announced that we would create Spark, a 3D printing software platform for developers to facilitate the advancement of 3D printing technology and begin manufacturing and selling Ember, an Autodesk-branded 3D printer. The Ember 3D printer became available for consumer purchase in February 2015.

Research and development expenditures were $725.2 million or 29% of fiscal 2015 net revenue, $611.1 million or 27% of fiscal 2014 net revenue and $600.0 million or 26% of fiscal 2013 net revenue. Our software is primarily developed internally; however, we also use independent firms and contractors to perform some of our product development activities. Additionally, we acquire products or technology developed by others by purchasing or licensing products and technology from third parties. We continually review these investments in an effort to ensure that we are generating sufficient revenue or gaining a competitive advantage to justify their costs.

The majority of our research and product development is performed in the United States, China, Singapore, and Canada. However, we employ experienced software developers in many of our other locations. Translation and localization of our products are performed in a number of local markets, principally Singapore and Switzerland. We generally localize and translate our products into German, French, Italian, Spanish, Russian, Japanese, Korean, and simplified and traditional Chinese.

We plan to continue to manage significant product development operations internationally over the next several years. We believe that our ability to conduct research and development at various locations throughout the world allows us to optimize product development, lower costs, and integrate local market knowledge into our development activities. We continually assess the significant costs and challenges, including intellectual property protection, against the benefits of our international development activities.

2015 Form 10-K 8

In addition, our business and our customers benefit from our relationships with a network of over 4,000 third-party developers who develop and sell their own products that further enhance the range of integrated solutions available to our customers.

For further discussion regarding risks from our product development and introduction efforts, see Item 1A, “Risk Factors.”

MARKETING AND SALES

We license or sell our products and services globally, primarily through indirect channels consisting of distributors and resellers. To a lesser extent we also transact directly with a select set of customers who are primarily large corporations. Our indirect channel model includes both a two-tiered distribution structure, where distributors sell to resellers, and a one-tiered structure, where Autodesk sells directly to resellers. We have a network of approximately 2,200 resellers and distributors worldwide. For fiscal 2015, approximately 83% of our revenue was derived from indirect channel sales through distributors and resellers, and we expect that the majority of our revenue will continue to be derived from indirect channel sales in the future. We anticipate that our channel mix will change to support our new business model and plan to proactively work with our channel partners to ensure a smooth transition. We employ a variety of incentive programs and promotions to align our reseller channel with our business strategies. Sales through our largest distributor, Tech Data Corporation and its affiliates, accounted for 25%, 24%, and 23% of our net revenue for fiscal years 2015, 2014, and 2013, respectively. We believe our business is not substantially dependent on Tech Data. Our customers through Tech Data are the resellers and end users who purchase our software licenses and services. Should any of the agreements between us and Tech Data be terminated for any reason, we believe the resellers and end users who currently purchase our products through Tech Data would be able to continue to do so under substantially the same terms from one of our many other distributors without substantial disruption to our revenue. No other distributor, reseller, or direct customer accounted for 10% or more of our revenue.

Our customer-related operations are divided into three geographic regions, the Americas; Europe, Middle East, and Africa (“EMEA”), and Asia Pacific (“APAC”). Each geographic region is supported by global marketing and sales organizations. These organizations develop and manage overall marketing and sales programs and work closely with a network of domestic and international sales offices. Fiscal 2015 net revenue in the Americas, EMEA, and APAC was $898.0 million (36%), $980.0 million (39%), and $634.2 million (25%), respectively. We intend to continue to make our products available in foreign languages. We believe that international sales will continue to comprise the majority of our total net revenue. Adverse economic conditions and currency exchange rates in the countries that contribute a significant portion of our net revenue, including emerging economies, may have an adverse effect on our business in those countries and our overall financial performance. A summary of our financial information by geographic location is found in Note 13, “Segments,” in the Notes to Consolidated Financial Statements. Our international operations and sales subject us to a variety of risks; see Item 1A, “Risk Factors,” for further discussion.

We also work directly with reseller and distributor sales organizations, computer manufacturers, other software developers, and peripherals manufacturers in cooperative advertising, promotions, and trade-show presentations. We employ mass-marketing techniques such as webcasts, seminars, telemarketing, direct mailings, sponsorships, advertising in business and trade journals, and social media. We have a worldwide user group organization and we have created online user communities dedicated to the exchange of information related to the use of our products.

In addition to sales of new perpetual use software licenses, we generate revenue through several subscription-based business models. The largest is our maintenance program, under which customers who own a perpetual use license for the most recent version of the underlying product are able to purchase maintenance that provides them with unspecified upgrades when-and-if-available and are able to download e-Learning courses and receive online support over a one year or multi-year maintenance service period. We also offer more flexible term-based license offerings to our customers.

Our ability to effectively distribute our products depends in part upon the financial and business condition of our distributor and reseller networks. The loss of, or a significant reduction in, business with any one of our major distributors or large resellers could harm our business; see Item 1A, “Risk Factors,” for further discussion.

2015 Form 10-K 9

CUSTOMER AND RESELLER SUPPORT

We provide technical support and training to customers through a leveraged support model, augmented by direct programs designed to address certain specific needs. Our customers rely primarily on the resellers and distributors from which they purchased licenses to our products for technical support; however, we do provide certain direct support for some of our customers. We support our resellers and distributors through technical product training, sales training classes, the Internet, and telephone. We also provide online support directly to our customers through our maintenance program. There are also a number of user group forums in which customers are able to share information.

EDUCATION, SUSTAINABILITY, AND PHILANTHROPIC PROGRAMS

Education

Our Education initiatives inspire the youth of today to imagine, design, and create a better world by offering free educational licenses of Autodesk software worldwide to students, educators, and educational institutions.

We help fuel a lifelong passion for design in students of all ages and collaborate with educators, institutions, and partners that encourage design learning and further Science, Technology, Engineering, Digital Arts, and Math (STEAM) education objectives.  Within the secondary and postsecondary global education markets, our learning content and standards based curriculum enable tomorrow’s workforce to graduate industry-ready, with marketable design skills that are in high demand.   Whether these students are future professional designers or lifelong design hobbyists, our full portfolio of professional-grade and personal design products introduces students and educators at all levels to software that can unleash their creativity.

Sustainability

To help our customers imagine, design, and create a better world, our Sustainability Programs focus our efforts where we can have the greatest impact: providing sustainability solutions, delivering sustainable design learning and training opportunities, expanding access to technology, and leading by example with our sustainable business practices. This benefits our customers, who use our products and services to improve design decisions that have substantial and long-term environmental impacts. Through access to free resources including the Autodesk Sustainability Workshop, Building Performance Analysis Certificate ("BPAC") Program and building design courses, students and professionals are learning how to use design technology and analytics to make better, more sustainable design decisions during the design process.

Philanthropy

The Autodesk Foundation (the "Foundation"), a privately funded 501(c)(3) charity organization established and solely funded by us, leads our philanthropic efforts. The purpose of the Foundation is twofold: to support employees to create a better world at work, at home, and in the community by matching employee’s volunteer time and/or donations to nonprofit organizations; and to support organizations and individuals using design to drive positive social and environmental impact. In the latter case, we use grant funding, software donations, and training to accomplish this goal, selecting the most impactful and innovative organizations around the world, thus, leading to a better future for our planet. On our behalf, the Foundation also administers a discounted software donation program to nonprofit organizations, social and environmental entrepreneurs, and others who are developing design solutions that will shape a more sustainable future.

DEVELOPER PROGRAMS

One of our key strategies is to maintain an open-architecture design of our software products to facilitate third-party development of complementary products and industry-specific software solutions. This approach enables customers and third parties to customize solutions for a wide variety of highly specific uses. We offer several programs that provide marketing, sales, technical support, and programming tools to developers who develop add-on applications for our products. Over 4,000 developers in the Autodesk Developer Network create interoperable products that further enhance the range of integrated solutions available to our customers.

COMPETITION

The markets for our products are highly competitive and subject to rapid change. We strive to increase our competitive separation by investing in research and development, allowing us to bring new products to market and create exciting new versions of existing products that offer compelling efficiencies for our customers. We also compete through investments in marketing and sales to more effectively reach new customers and better serve existing customers.

2015 Form 10-K 10

Our competitors include large, global, publicly traded companies; small, geographically focused firms; startup firms; and solutions produced in-house by their users. Our primary global competitors in the PSEB, AEC, and MFG segments include Adobe Systems Incorporated, ANSYS, Inc., AVEVA Group plc, Bentley Systems, Incorporated, Dassault Systèmes S.A. and its subsidiary Dassault Systèmes SolidWorks Corp., Environmental Systems Research Institute, Inc. (ESRI), Intergraph Corporation, a wholly owned subsidiary of Hexagon AB, MSC Software Corporation, Nemetschek AG, PTC, 3D Systems, Seimens PLM, and Trimble Navigation Limited.

Our M&E segment also competes with a wide range of different companies from large, global, publicly-traded companies to small private entities. Large organizations that produce products that compete in some or all of our markets include Adobe Systems Incorporated, Apple Inc., Avid Technology, Inc., SONY Corporation, and Technicolor, among others. The media and entertainment market is highly fragmented with complex interdependencies between many of the larger businesses. As a result, some of our competitors also own subsidiaries that are our customers or our partners in developing or bringing to market some of our solutions. In addition to traditional competitors in developed economies, we encounter new competitors in emerging economies.

The software industry has limited barriers to entry, and the availability of computing power with continually expanding performance at progressively lower prices contributes to the ease of market entry. The industry is presently undergoing a platform shift from the personal computer to cloud and mobile computing. This shift further lowers barriers to entry and poses a disruptive challenge to established software companies. The design software market is characterized by vigorous competition in each of the vertical markets in which we compete, both from existing competitors and by entry of new competitors with innovative technologies. Competition is increasingly enhanced by consolidation of companies with complementary products and technologies and the possibility that competitors in one vertical segment may enter other vertical segments that we serve. In addition, some of our competitors in certain markets have greater financial, technical, sales and marketing, and other resources than we do. Because of these and other factors, competitive conditions in these industries are likely to continue to intensify in the future. Increased competition could result in price reductions, reduced net revenue and profit margins, and loss of market share, any of which could harm our business. See Item 1A, “Risk Factors,” for further discussion of risks regarding competition.

We believe that our future results depend largely upon our ability to better serve customers by offering new products, including cloud and mobile computing products, whether by internal development or acquisition, and to continue to provide existing product offerings that compete favorably with respect to ease of use, reliability, performance, range of useful features, continuing product enhancements, reputation, price, and training.

INTELLECTUAL PROPERTY AND LICENSES

We maintain an active program to legally protect our investment in technology through intellectual property rights. We protect our intellectual property through a combination of patent, copyright, trademark and trade secret protections, confidentiality procedures, and contractual provisions. The nature and extent of legal protection associated with each such intellectual property right depends on, among other things, the type of intellectual property right and the given jurisdiction in which such right arises. We believe that our intellectual property rights are valuable and important to our business, including each of our segments.

Nonetheless, our intellectual property rights may not be successfully asserted in the future or may be invalidated, circumvented or challenged. In addition, the laws and enforcement of the laws of various foreign countries where our products are distributed do not protect our intellectual property rights to the same extent as U.S. laws. Enforcement of intellectual property rights against alleged infringers can sometimes lead to costly litigation and counterclaims. Our inability to protect our proprietary information could harm our business.

From time to time, we receive claims alleging infringement of a third party’s intellectual property rights, including patents. Disputes involving our intellectual property rights or those of another party have in the past and may in the future lead to, among other things, costly litigation or product shipment delays, which could harm our business.

We retain ownership of software we develop. Desktop software is licensed to users pursuant to ‘click through’ or signed license agreements containing restrictions on duplication, disclosure, and transfer. Cloud software and associated services are provided to users pursuant to on-line or signed terms of service agreements containing restrictions on access and use.

2015 Form 10-K 11

We believe that because of the limitations of laws protecting our intellectual property and the rapid, ongoing technological changes in both the computer hardware and software industries, we must rely principally upon software engineering and marketing skills to continually maintain and enhance our competitive market position.

While we have recovered some revenue resulting from the unauthorized use of our software products, we are unable to measure the full extent to which piracy of our software products exists. We believe, however, that software piracy is and can be expected to be a persistent problem that negatively impacts our revenue and financial results. We believe that our transition from perpetual use software licenses to a subscription-based business model combined with the change from desktop to cloud-based computing will shift the incentives and means by which software is pirated.

In addition, through various licensing arrangements, we receive certain rights to intellectual property of others. We expect to maintain current licensing arrangements and to secure licensing arrangements in the future, as needed and to the extent available on reasonable terms and conditions, to support continued development and sales of our products and services. Some of these licensing arrangements require or may require royalty payments and other licensing fees. The amount of these payments and fees may depend on various factors, including but not limited to: the structure of royalty payments, offsetting considerations, if any, and the degree of use of the licensed technology.

See Item 1A, “Risk Factors,” for further discussion of risks related to protecting our intellectual property.

PRODUCTION AND SUPPLIERS

The production of our PSEB, AEC, MFG, and certain M&E software products involves duplication of the software media. The purchase of media and the transfer of the software programs onto media for distribution to customers are performed by us and by licensed subcontractors. Media for our products such as DVDs and USB flash drives are available from multiple sources. For certain products and countries, we offer customers an electronic software download option for both initial product fulfillment as well as product updates for maintenance subscribers. Customers who choose electronic fulfillment receive the latest version of the software from our vendor’s secure servers. For certain cloud-based products, we use a combination of co-located hosting facilities as well as infrastructure-as-a-service providers like Amazon Web Services. Packaging materials are produced to our specifications by outside sources. Production is performed in leased facilities operated by independent third-party contractors. To date, we have not experienced any material difficulties or delays in the production of our software and documentation.

EMPLOYEES

As of January 31, 2015, we employed approximately 8,823 people. None of our employees in the United States are represented by a labor union. In certain foreign countries, our employees are represented by work councils. We have never experienced any work stoppages and believe our employee relations are good. Reliance upon employees in other countries entails various risks and changes in these foreign countries, such as government instability or regulation unfavorable to foreign-owned businesses, which could negatively impact our business in the future.

BACKLOG

We typically ship products shortly after receipt of an order, which is common in the software industry. Our backlog consists of current software license product orders which have not yet shipped. The category of current software license product orders which we have not yet shipped consists of orders from customers with approved credit status for currently available software products.

Backlog was $40.4 million at January 31, 2015 compared to $19.7 million at January 31, 2014. The actual amount of backlog at any particular time may not be a meaningful indicator of future business prospects as this amount is impacted by a number of factors not related to future trends or events such as the order fulfillment process, the method of software delivery or the linearity of our business within the fiscal period.

GLOSSARY OF TERMS

Billings—Amounts billed to customers during the current fiscal period net of any partner incentives or other discounts.

2015 Form 10-K 13

BIM (Building Information Modeling)—BIM describes a model-based technology linked with a database of project information, and is the process of generating and managing information throughout the life cycle of a building. BIM is used as a digital representation of the building process to facilitate exchange and interoperability of information in digital formats.

Constant currency growth rates—We attempt to represent the changes in the underlying business operations by eliminating fluctuations caused by changes in foreign currency exchange rates as well as eliminating hedge gains or losses recorded within the current and comparative periods. Our constant currency methodology removes all hedging gains and losses from the calculation.

Digital prototyping—Digital prototyping allows designers, architects and engineers to analyze, simulate, and visualize a design using a digital or virtual model rather than a physical model.

Flagship—Autodesk flagship products are our core design products. Flagship includes the following products: 3ds Max, AutoCAD, AutoCAD LT, AutoCAD vertical products (such as AutoCAD Architecture and Mechanical), Civil 3D, Inventor products (standalone), Map 3D, Maya, and Revit products (standalone).

License and Other revenue—License and other revenue consists of two components: (1) all forms of product license revenue and (2) other revenue. Product license revenue includes software license revenue from the sale of seat licenses, term-based licenses from our desktop subscription and enterprise offerings, and product revenue for Creative Finishing. Other revenue includes revenue from consulting, training, Autodesk Developers Network and Creative Finishing customer support, and is recognized over time, as the services are performed.

Maintenance—Our maintenance program provides our customers with a cost effective and predictable budgetary option to obtain the productivity benefits of our new releases and enhancements when and if released during the term of their contracts. Under our maintenance program, customers are eligible to receive unspecified upgrades when and if available, downloadable training courses and online support. We recognize maintenance revenue over the term of the agreements, generally between one and three years.

New and Adjacent—Autodesk new and adjacent products include Autodesk's new product offerings as well as products that are not included in flagship or suites. New and adjacent includes the following services and products: Autodesk Alias Design products, Autodesk 360 products, Autodesk Consulting, Autodesk Simulation, Autodesk Simulation Multiphysics, Autodesk Buzzsaw, Autodesk CF Design, Autodesk Constructware, Autodesk Consumer products, Autodesk Creative Finishing products, Delcam products, Autodesk Moldflow products, Autodesk Navisworks, Autodesk Scaleform, Autodesk Vault products, and all other products.

Suites—Autodesk design suites are a combination of products that target a specific user objective (product design, building design, etc.) and support a set of workflows for that objective. Our current design and creation suites include: AutoCAD Design Suite, Autodesk Building Design Suite, Autodesk Entertainment Creation Suite, Autodesk Factory Design Suite, Autodesk Infrastructure Design Suite, Autodesk Plant Design Suite, and Autodesk Product Design Suite.

Subscription revenue—Autodesk subscription revenue consists of three components:  (1) maintenance revenue from our software products; (2) maintenance revenue from our term-based desktop subscription and enterprise offerings; and (3) revenue from our cloud service offerings.

Total Subscriptions—Consists of subscriptions from our maintenance, desktop, cloud service and enterprise license offerings that are active as of the quarter end date. For certain cloud based and enterprise license offerings, subscriptions represent the monthly average activity reported within the last three months of the quarter end date. Total subscriptions do not include data from education offerings, consumer product offerings, certain Creative Finishing product offerings, Autodesk Buzzsaw, Autodesk Constructware, and third party products. Subscriptions acquired with the acquisition of a business are captured once the data conforms to our subscription count methodology and when added, may cause variability in the comparison of this calculation.

ITEM 1A.RISK FACTORS

We operate in a rapidly changing environment that involves significant risks, a number of which are beyond our control. In addition to the other information contained in this Form 10-K, the following discussion highlights some of these risks and the possible impact of these factors on our business, financial condition, and future results of operations. If any of the following risks actually occur, our business, financial condition, or results of operations may be adversely impacted, causing the trading price of our common stock to decline. In addition, these risks and uncertainties may impact the “forward-looking” statements described elsewhere in this Form 10-K and in the documents incorporated herein by reference. They could affect our actual results of operations, causing them to differ materially from those expressed in “forward-looking” statements.

Global economic and political conditions may further impact our business, financial results, and financial condition.

As our business has expanded globally, we have increasingly become subject to risks arising from adverse changes in global economic and political conditions. The past several years were characterized by weak global economic conditions, volatile credit markets, relatively high unemployment, a low level of liquidity in many financial markets, increased government deficit spending and debt levels, uncertainty about certain governments' abilities to repay such debt or to address certain fiscal issues, and volatility in many financial instrument markets. If economic growth in countries where we do business slows, or if such countries experience further economic recessions, customers may delay or reduce technology purchases. This could result in reductions in sales of our products and services, longer sales cycles, and slower adoption of our technologies.

Over the past several years, many of our customers have experienced tighter credit, negative financial news, and weaker financial performance of their businesses and have reduced their workforces, thereby reducing the number of licenses and the number of maintenance contracts they purchase from us. In addition, a number of our customers rely, directly and indirectly, on government spending. Current debt balances of many countries without proportionate increases in revenues have caused many countries to reduce spending and in some cases have forced those countries to restructure their debt in an effort to avoid defaulting under those obligations. This has not only impacted those countries but others that are holders of such debt and those assisting in such restructuring.

These actions may impact, and over the past several years have negatively impacted, our business, financial results, and financial condition. Moreover, our financial performance may be negatively impacted by:

• lack of credit available to and the insolvency of key channel partners, which may impair our distribution channels and cash flows;

• counterparty failures negatively impacting our treasury functions, including timely access to our cash reserves and third-party fulfillment of hedging transactions;

• counterparty failures negatively affecting our insured risks;

• inability of banks to honor our existing line of credit, which could increase our borrowing expenses or eliminate our ability to obtain short-term financing; and

• decreased borrowing and spending by our end users on small and large projects in the industries we serve, thereby reducing demand for our products.

Uncertainty about current and future economic and political conditions on us, our customers and partners, makes it difficult for us to forecast operating results and to make decisions about future investments.

A slower economic recovery in industries important to our business may adversely affect our business, financial results, and financial condition. If a macro-economic recovery does not occur as rapidly as anticipated, our ability to meet our long-term financial targets may also be adversely affected.

If we fail to successfully manage our business model transition to cloud-based products and more flexible product licenses, our results of operations could be negatively impacted.

To address the industry transition from personal computer to cloud, social, and mobile computing, we have accelerated our move to the cloud and are offering more flexible product licenses. As part of this transition, we announced in fiscal 2014 that we are discontinuing upgrades after fiscal 2015 and, on February 4, 2015, we also announced that new commercial seats of

2015 Form 10-K 15

most standalone software products will be available only by desktop subscription beginning February 1, 2016. As a result, we expect to derive an increasing portion of our revenues in the future from subscriptions. This subscription model prices and delivers our products in a way that differs from the historical perpetual pricing and delivery methods. These changes reflect a significant shift from perpetual license sales and distribution of our software in favor of providing our customers the right to access certain of our software in a hosted environment or use downloaded software for a specified subscription period.

Our ability to achieve our financial objectives is subject to risks and uncertainties. The new offerings require a considerable investment of technical, financial, legal, and sales resources, and a scalable organization. Market acceptance of such offerings is affected by a variety of factors, including but not limited to: security, reliability, performance, current license terms, customer preference, social/community engagement, customer concerns with entrusting a third party to store and manage their data, public concerns regarding privacy and the enactment of restrictive laws or regulations. Whether our business model transition will prove successful and will accomplish our business and financial objectives is subject to numerous uncertainties, including but not limited to: customer demand, attach and renewal rates, channel acceptance, our ability to further develop and scale infrastructure, our ability to include functionality and usability in such offerings that address customer requirements, tax and accounting implications, pricing, and our costs. In addition, the metrics we use to gauge the status of our business model transition may evolve over the course of the transition as significant trends emerge.  If we are unable to successfully establish these new offerings and navigate our business model transition in light of the foregoing risks and uncertainties, our results of operations could be negatively impacted.

Our strategy to develop and introduce new products and services exposes us to risks such as limited customer acceptance, costs related to product defects, and large expenditures that may not result in additional net revenue or could result in decreased net revenue.

Rapid technological changes, as well as changes in customer requirements and preferences, characterize the software industry. Just as the transition from mainframes to personal computers transformed the industry 30 years ago, we believe our industry is undergoing a similar transition from the personal computer to cloud, mobile, and social computing. Customers are also reconsidering the manner in which they license software products, which requires us to constantly evaluate our business model and strategy. In response, we are focused on providing solutions to enable our customers to be more agile and collaborative on their projects. We are also developing consumer products for digital art, personal design and creativity, and home design. We devote significant resources to the development of new technologies. In addition, we frequently introduce new business models or methods that require a considerable investment of technical and financial resources such as an increase in our portfolio of, and focus on, suites and, most recently, our introduction of flexible license and service offerings. We are making such investments through further development and enhancement of our existing products and services, as well as through acquisitions of new product lines. Such investments may not result in sufficient revenue generation to justify their costs and could result in decreased net revenue. For example, in fiscal 2015, we announced that we would create Spark, a 3D printing software platform for developers to facilitate the advancement of 3D printing technology, and begin manufacturing and selling Ember, an Autodesk-branded 3D printer. If we are not able to meet customer requirements, either with respect to our software or hardware products or the manner in which we provide such products, or if we are not able to adapt our business model to meet our customers' requirements, our business, financial condition or results of operations may be adversely impacted.

In particular, a critical component of our growth strategy is to have customers of our AutoCAD and AutoCAD LT products expand their portfolios to include our suites and cloud-based services. We want customers using standalone Autodesk products to expand their portfolio with our suites and cloud-based offerings, and we are taking steps to accelerate this migration. At times, sales of licenses of our AutoCAD and AutoCAD LT or standalone Autodesk flagship products have decreased without a corresponding increase in suites product or cloud-based services revenue or without purchases of customer seats to our suites. Should this continue, our results of operations will be adversely affected. Also, adoption of our cloud and mobile computing offerings and changes in the delivery of our software and services to our customers, such as desktop subscription (formally referred to as rental) offerings, will change the way in which we recognize revenue relating to our software and services, with a potential negative impact on our financial performance. The accounting impact of these offerings and other business decisions are expected to result in an increase in the percentage of our ratable revenue, as well as recurring revenue, making for a more predictable business over time, while potentially reducing our upfront perpetual revenue stream. Additionally, the software products we offer are complex, and despite extensive testing and quality control, may contain errors or defects. These errors or defects could result in the need for corrective releases to our software products, damage to our reputation, loss of revenue, an increase in product returns or lack of market acceptance of our products, any of which would likely harm our business.

Our executive management team must act quickly, continuously, and with vision, given the rapidly changing customer expectations and technology advancements inherent in the software industry, the extensive and complex efforts required to

2015 Form 10-K 16

create useful and widely accepted products and the rapid evolution of cloud computing, mobile devices, new computing platforms, and other technologies, such as consumer products. Although we have articulated a strategy that we believe will fulfill these challenges, if we fail to execute properly on that strategy or adapt that strategy as market conditions evolve, we may fail to meet our customers' expectations, fail to compete with our competitors' products and technology, and lose the confidence of our channel partners and employees. This in turn could adversely affect our business and financial performance.

Our entry into 3D printing presents many of the risks described above concerning developing and introducing new products as well as new risks for us. The manufacturing and 3D printing markets are highly competitive and some of our competitors have superior experience and resources to us. We have limited experience designing, developing, and selling hardware products and no experience developing and selling printers. The market for 3D printing is nascent and may not develop as rapidly as we expect. Our sale of 3D printers could subject us to product and other liability that we do not currently face. If any of these risks materialize, it could adversely affect our business and financial performance as well as our reputation and brand.

We are dependent on international revenue and operations, exposing us to significant regulatory, global economic, intellectual property, collections, currency exchange rate, taxation, political instability, and other risks, which could adversely impact our financial results.

We are dependent on our international operations for a significant portion of our revenue. International net revenue represented 71% and 70% of our net revenue in fiscal 2015 and 2014, respectively. Our international revenue, including that from emerging economies, is subject to general economic and political conditions in foreign markets, including conditions in foreign markets resulting from economic and political conditions in the U.S. Our revenue is also impacted by the relative geographical and country mix of our revenue over time. At times, these factors adversely impact our international revenue, and consequently our business as a whole. Our dependency on international revenue makes us much more exposed to global economic and political trends, which can negatively impact our financial results, even if our results in the U.S. are strong for a particular period. Further, a significant portion of our earnings from our international operations may not be freely transferable to the U.S. due to remittance restrictions, adverse tax consequences or other factors. Our intent is that amounts related to foreign earnings permanently reinvested outside the U.S. will remain outside the U.S., and we will meet our U.S. liquidity needs through ongoing cash flows, external borrowings (such as our senior notes), or both. However, if, in the future, amounts held by foreign subsidiaries are needed to fund our operations in the U.S., or to service our external borrowings, the repatriation of such amounts to the U.S. could result in a significant incremental tax liability in the period in which the decision to repatriate occurs and payment of any such tax liability would reduce the cash available to fund our operations.

We anticipate that our international operations will continue to account for a significant portion of our net revenue, and, as we expand our international development, sales and marketing expertise, will provide significant support to our overall efforts in countries outside of the U.S. Risks inherent in our international operations include:

• fluctuating currency exchange rates, including risks related to any hedging activities we undertake;

• unexpected changes in regulatory requirements and practices;

• delays resulting from difficulty in obtaining export licenses for certain technology;

• tariffs, quotas, and other trade barriers and restrictions;

• transportation delays;

• operating in locations with a higher incidence of corruption and fraudulent business practices, particularly in emerging economies;

• increasing enforcement by the U.S. under the Foreign Corrupt Practices Act, adoption of stricter anti-corruption laws in certain countries, including the United Kingdom;

• difficulties in staffing and managing foreign sales and development operations,

• longer collection cycles for accounts receivable;

2015 Form 10-K 17

• potential changes in tax laws, including possible U.S. and foreign tax law changes that, if enacted, could significantly impact how multinational companies are taxed;

• tax arrangements with foreign governments, including our ability to meet and renew the terms of those tax arrangements;

• laws regarding the management of and access to data and public networks;

• possible future limitations upon foreign owned businesses;

• increased financial accounting and reporting burdens and complexities;

• inadequate local infrastructure;

• greater difficulty in protecting intellectual property; and

• other factors beyond our control, including popular uprisings, terrorism, war, natural disasters, and diseases.

Some of our business partners also have international operations and are subject to the risks described above. Even if we are able to successfully manage the risks of international operations, our business may be adversely affected if our business partners are not able to successfully manage these risks.

Existing and increased competition and rapidly evolving technological changes may reduce our revenue and profits.

The software industry has limited barriers to entry, and the availability of computing devices with continually expanding performance at progressively lower prices contributes to the ease of market entry. The industry is presently undergoing a platform shift from the personal computer to cloud and mobile computing. This shift further lowers barriers to entry and poses a disruptive challenge to established software companies. The markets in which we compete are characterized by vigorous competition, both by entry of competitors with innovative technologies and by consolidation of companies with complementary products and technologies. In addition, some of our competitors in certain markets have greater financial, technical, sales and marketing, and other resources. Furthermore, a reduction in the number and availability of compatible third-party applications, or our inability to rapidly adapt to technological and customer preference changes, including those related to cloud computing, mobile devices, and new computing platforms, may adversely affect the sale of our products. Because of these and other factors, competitive conditions in the industry are likely to intensify in the future. Increased competition could result in price reductions, reduced net revenue and profit margins and loss of market share, any of which would likely harm our business.

We are exposed to fluctuations in currency exchange rates that could negatively impact our financial results and cash flows.

Because we conduct a substantial portion of our business outside the U.S. and we make certain business and resource decisions based on assumptions about foreign currency, we face exposure to adverse movements in foreign currency exchange rates. These exposures may change over time as business practices evolve and economic conditions change, and they could have a material adverse impact on our financial results and cash flows.

We use derivative instruments to manage a portion of our cash flow exposure to fluctuations in foreign currency exchange rates. As part of our risk management strategy, we use foreign currency contracts to manage a portion of our exposures of underlying assets, liabilities, and other obligations, which exist as part of our ongoing business operations. These foreign currency instruments have maturities that extend for one to twelve months in the future, and provide us with some protection against currency exposures. However, our attempts to hedge against these risks may not be completely successful, resulting in an adverse impact on our financial results.

The fluctuations of currencies in which we conduct business can both increase and decrease our overall revenue and expenses for any given fiscal period. Although our foreign currency cash flow hedge program extends beyond the current quarter in order to reduce our exposure to foreign currency volatility, we do not attempt to completely mitigate this risk, and in any case, will incur transaction fees in adopting such hedging programs. Such volatility, even when it increases our revenues or decreases our expenses, impacts our ability to accurately predict our future results and earnings.

2015 Form 10-K 18

If we do not maintain good relationships with the members of our distribution channel, or achieve anticipated levels of sell-through, our ability to generate revenue will be adversely affected. If our distribution channel suffers financial losses, becomes financially unstable or insolvent, or is not provided the right mix of incentives to sell our products, our ability to generate revenue will be adversely affected.

We sell our software products both directly to end-users and through a network of distributors and resellers. For fiscal 2015 and fiscal 2014, approximately 83% and 84% of our revenue was derived from indirect channel sales through distributors and resellers, respectively, and we expect that the majority of our revenue will continue to be derived from indirect channel sales in the future. Our ability to effectively distribute our products depends in part upon the financial and business condition of our distributor and reseller network. Computer software distributors and resellers typically are not highly capitalized, have previously experienced difficulties during times of economic contraction and experienced difficulties during the past several years. We have processes to ensure that we assess the creditworthiness of distributors and resellers prior to our sales to them. In the past we have taken steps to support them, and may take additional steps in the future, such as extending credit terms and providing temporary discounts. These steps, if taken, could harm our financial results. If our distributors and resellers were to become insolvent, they would not be able to maintain their business and sales, or provide customer support services, which would negatively impact our business and revenue.

We rely significantly upon major distributors and resellers in both the U.S. and international regions, including the distributor Tech Data Corporation and its global affiliates (“Tech Data”). Tech Data accounted for 25% and 24% of our total net revenue for fiscal 2015 and 2014, respectively. Although we believe that we are not substantially dependent on Tech Data, if Tech Data were to experience a significant disruption with its business or if our relationship with Tech Data were to significantly deteriorate, it is possible that our ability to sell to end users would be, at least temporarily, negatively impacted. This could in turn negatively impact our financial results.

Over time, we have modified and will continue to modify aspects of our relationship with our distributors and resellers, such as their incentive programs, pricing to them and our distribution model to motivate and reward them for aligning their businesses with our strategy and business objectives. Changes in these relationships and underlying programs could negatively impact their business and harm our business. In addition, the loss of or a significant reduction in business with those distributors or resellers or the failure to achieve anticipated levels of sell-through with any one of our major international distributors or large resellers could harm our business. In particular, if one or more of such distributors or resellers were unable to meet their obligations with respect to accounts payable to us, we could be forced to write off such accounts and may be required to delay the recognition of revenue on future sales to these customers. These events could have a material adverse effect on our financial results.

Our financial results fluctuate within each quarter and from quarter to quarter making our future revenue and financial results difficult to predict.

Our quarterly financial results have fluctuated in the past and will continue to do so in the future. These fluctuations could cause our stock price to change significantly or experience declines. In addition to the other factors described in this Part I, Item 1A, some of the factors that could cause our financial results to fluctuate include:

• general market, economic, business, and political conditions in particular geographies, including Europe, APAC, and emerging economies;

• failure to produce sufficient revenue, billings or subscription growth, and profitability;

• failure to achieve anticipated levels of customer acceptance to our business model transition, including the impact of the end of upgrades and perpetual licenses;

• weak or negative growth in one or more of the industries we serve, including AEC, manufacturing, and digital media and entertainment markets;

• fluctuations in foreign currency exchange rates and the effectiveness of our hedging activity;

• failure to achieve and maintain cost reductions and productivity increases;

• dependence on and the timing of large transactions;

2015 Form 10-K 19

• changes in product mix, pricing pressure or changes in product pricing;

• changes in billings linearity;

• the ability of governments around the world to adopt fiscal policies, meet their financial and debt obligations, and to finance infrastructure projects;

• lower growth or contraction of our maintenance program;

• restructuring or other accounting charges and unexpected costs or other operating expenses;

• failure to expand our AutoCAD and AutoCAD LT customer base to related design products and services;

• our inability to rapidly adapt to technological and customer preference changes, including those related to cloud computing, mobile devices, new computing platforms, and 3D printing;

• the timing of the introduction of new products by us or our competitors;

• the success of new business or sales initiatives and increasing our portfolio of product suites;

• the financial and business condition of our reseller and distribution channels;

• failure to accurately predict the impact of acquired businesses or to identify and realize the anticipated benefits of acquisitions, and successfully integrate such acquired businesses and technologies;

• perceived or actual technical or other problems with a product or combination of products;

• unexpected or negative outcomes of matters and expenses relating to litigation or regulatory inquiries;

• increases in cloud services-related expenses;

• security breaches and potential financial penalties to customers and government entities;

• timing of additional investments in the development of our platform or deployment of our services;

• timing of product releases and retirements;

• changes in tax laws or regulations, tax arrangements with foreign governments or accounting rules, such as increased use of fair value measures;

• changes in revenue recognition or other accounting guidelines employed by us and/or established by the Financial Accounting Standards Board or other rule-making bodies;

• changes in sales compensation practices;

• failure to effectively implement our copyright legalization programs, especially in developing countries;

• failure to achieve sufficient sell-through in our channels for new or existing products;

• renegotiation or termination of royalty or intellectual property arrangements;

• interruptions or terminations in the business of our consultants or third-party developers;

• the timing and degree of expected investments in growth and efficiency opportunities;

• failure to achieve continued success in technology advancements;

• catastrophic events or natural disasters;

2015 Form 10-K 20

• regulatory compliance costs;

• potential goodwill impairment charges related to prior acquisitions; and

• adjustments arising from ongoing or future tax examinations.

We have also experienced fluctuations in financial results in interim periods in certain geographic regions due to seasonality or regional economic or political conditions. In particular, our financial results in Europe during our third quarter are usually affected by a slower summer period, and our Asia Pacific operations typically experience seasonal slowing in our third and fourth quarters.

Our operating expenses are based in part on our expectations for future revenue and are relatively fixed in the short term. Accordingly, any revenue shortfall below expectations has had, and in the future could have, an immediate and significant adverse effect on our profitability. Greater than anticipated expenses or a failure to maintain rigorous cost controls would also negatively affect profitability.

Our business could suffer as a result of risks, costs, and charges associated with strategic acquisitions and investments.

We regularly acquire or invest in businesses, software products and technologies that are complementary to our business through acquisitions, strategic alliances or equity or debt investments. For example, in fiscal 2015 we acquired Delcam, a leading supplier of advanced CADCAM and industrial measurement solutions for the manufacturing industry. The risks associated with such acquisitions include, among others, the difficulty of assimilating products, operations and personnel, inheriting liabilities such as intellectual property infringement claims, the failure to realize anticipated revenue and cost projections, the requirement to test and assimilate the internal control processes of the acquired business in accordance with the requirements of Section 404 of the Sarbanes-Oxley Act of 2002, and the diversion of management's time and attention.

In addition, such acquisitions and investments involve other risks such as:

• the inability to retain customers, key employees, vendors, distributors, business partners, and other entities associated with the acquired business;

• the potential that due diligence of the acquired business or product does not identify significant problems;

• exposure to litigation or other claims in connection with, or inheritance of claims or litigation risk as a result of, an acquisition, including but not limited to, claims from terminated employees, customers, or other third parties;

• the potential for incompatible business cultures;

• significant higher than anticipated transaction or integration-related costs;

• potential additional exposure to fluctuations in currency exchange rates; and

• the potential impact on relationships with existing customers, vendors, and distributors as business partners as a result of acquiring another business.

We may not be successful in overcoming such risks, and such acquisitions and investments may negatively impact our business. In addition, such acquisitions and investments have in the past and may in the future contribute to potential fluctuations in our quarterly financial results. These fluctuations could arise from transaction-related costs and charges associated with eliminating redundant expenses or write-offs of impaired assets recorded in connection with acquisitions and investments. These costs or charges could negatively impact our financial results for a given period, cause quarter to quarter variability in our financial results or negatively impact our financial results for several future periods.

Because we derive a substantial portion of our net revenue from a small number of products, including our AutoCAD-based software products and suites, if these products are not successful, our revenue will be adversely affected.

We derive a substantial portion of our net revenue from sales of licenses of a limited number of our products, including AutoCAD software, products based on AutoCAD, which include our suites that serve specific markets and products that are interoperable with AutoCAD. Any factor adversely affecting sales of these products, including the product release cycle, market acceptance, product competition, performance and reliability, reputation, price competition, economic and market conditions, and the availability of third-party applications, would likely harm our financial results. During fiscal 2015 and 2014, combined revenue from our AutoCAD and AutoCAD LT products, not including suites having AutoCAD or AutoCAD LT as a component, represented 28% and 30% of our total net revenue, respectively.

A breach of security in our products, services or computer systems may compromise the integrity of our products or services, harm our reputation, create additional liability and adversely impact our financial results.

We make significant efforts to maintain the security and integrity of our source code and computer systems. The risk of a security breach or disruption, particularly through cyber attack or cyber intrusion, including by computer hackers, foreign governments and cyber terrorists, has increased as the number, intensity, and sophistication of attempted attacks and intrusions from around the world have increased. These threats include but are not limited to identity theft, unauthorized access, DNS attacks, wireless network attacks, viruses and worms, advanced persistent threat (APT), application centric attacks, peer-to-peer attacks, phishing, backdoor trojans, and distributed denial of service (DDoS) attacks. Any of the foregoing could attack our products, services or computer systems. Despite significant efforts to create security barriers to such programs, it is virtually impossible for us to entirely eliminate this risk. Like all software, our software is vulnerable to cyber attacks. In the past, hackers have targeted our software, and they may do so in the future. The impact of cyber attacks could disrupt the proper functioning of our software products or services, cause errors in the output of our customers' work, allow unauthorized access to sensitive, proprietary or confidential information of ours or our customers, and other destructive outcomes. Moreover, as we continue to invest in new lines of consumer products and services we are exposed to increased security risks and the potential for unauthorized access to, or improper use of, the information of our consumer users. If any of the foregoing were to occur, our reputation may suffer, customers may stop buying our products or services, we could face lawsuits and potential liability, and our financial performance could be negatively impacted.

We rely on third parties to provide us with a number of operational services, including hosting and delivery and certain of our customer services and other operations. Any interruption or delay in service from these third parties, breaches of security or privacy, or failures in data collection could expose us to liability, harm our reputation, and adversely impact our financial performance.

We rely on hosted computer services from third parties for services that we provide our customers and computer operations for our internal use. As we gather customer data and host certain customer data in third-party facilities, a security breach could compromise the integrity or availability or result in the theft of customer data. In addition, our operations could be negatively affected in the event of a security breach, and we could be subject to the loss or theft of confidential or proprietary information, including source code.

Unauthorized access to this data may be obtained through break-ins, breaches of our secure networks by unauthorized parties, employee theft or misuse, or other misconduct. We rely on a number of third-party suppliers in the operation of our business for the provision of various services and materials that we use in the operation of our business and production of our products. Although we seek to diversify our third-party suppliers, we may from time to time rely on a single or limited number of suppliers, or upon suppliers in a single country, for these services or materials. The inability of such third parties to satisfy our requirements could disrupt our business operations or make it more difficult for us to implement our business strategy. If any of these situations were to occur, our reputation could be harmed, we could be subject to third-party liability, including under data protection and privacy laws in certain jurisdictions, and our financial performance could be negatively impacted.

If we are not able to adequately protect our proprietary rights, our business could be harmed.

We rely on a combination of patent, copyright and trademark laws, trade secret protections, confidentiality procedures, and contractual provisions to protect our proprietary rights. Despite such efforts to protect our proprietary rights, unauthorized parties from time to time have copied aspects of our software products or have obtained and used information that we regard as proprietary. Policing unauthorized use of our software products is time-consuming and costly. We are unable to measure the

2015 Form 10-K 22

extent to which piracy of our software products exists and we expect that software piracy will remain a persistent problem, particularly in emerging economies. Furthermore, our means of protecting our proprietary rights may not be adequate.

Additionally, we actively protect the secrecy of our confidential information and trade secrets, including our source code. If unauthorized disclosure of our source code occurs, we could potentially lose future trade secret protection for that source code. The loss of future trade secret protection could make it easier for third parties to compete with our products by copying functionality, which could adversely affect our financial performance and our reputation. We also seek to protect our confidential information and trade secrets through the use of non-disclosure agreements with our customers, contractors, vendors, and partners. However, it is possible that our confidential information and trade secrets may be disclosed or published without our authorization. If this were to occur, it may be difficult and/or costly for us to enforce our rights, and our financial performance and reputation could be negatively impacted.

We may face intellectual property infringement claims that could be costly to defend and result in the loss of significant rights.

As more software patents are granted worldwide, the number of products and competitors in our industry segments grows and the functionality of products in different industry segments overlaps, we expect that software product developers will be increasingly subject to infringement claims. Infringement or misappropriation claims have in the past been, and may in the future be, asserted against us, and any such assertions could harm our business. Additionally, certain patent holders without products have become more aggressive in threatening and pursuing litigation in attempts to obtain fees for licensing the right to use patents. Any such claims or threats, whether with or without merit, have been and could in the future be time-consuming to defend, result in costly litigation and diversion of resources, cause product shipment delays, or require us to enter into royalty or licensing agreements. In addition, such royalty or license agreements, if required, may not be available on acceptable terms, if at all, which would likely harm our business.

A significant portion of our revenue is generated through maintenance revenue. Decreases in maintenance attach or renewal rates or a decrease in the number of new licenses we sell would negatively impact our future revenue and financial results.

Our maintenance customers have no obligation to attach maintenance to their initial license or renew their maintenance contract after the expiration of their initial maintenance period, which is typically one year. Our customers' attach and renewal rates may decline or fluctuate as a result of a number of factors, including the overall global economy, the health of their businesses, and the perceived value of the maintenance program. If our customers do not attach maintenance to their initial license or renew their maintenance contract for our products, our maintenance revenue will decline and our financial results will suffer.

In addition, a portion of the growth of our maintenance revenue has typically been associated with growth of the number of licenses that we sell. Any reduction in the number of licenses that we sell, even if our customers' attach rates do not change, will have a negative impact on our future maintenance revenue. This in turn would impact our business and harm our financial results.

We recognize maintenance revenue ratably over the term of the maintenance contracts, which is predominantly one year, but may also range up to five years. Decreases in maintenance billings will negatively impact future maintenance revenue, however future maintenance revenue will also be impacted by other factors such as the amount, timing, and mix of contract terms of future billings.

From time to time we realign or introduce new business and sales initiatives; if we fail to successfully execute and manage these initiatives, our results of operations could be negatively impacted.

As part of our effort to accommodate our customers' needs and demands and the rapid evolution of technology, we from time to time evolve our business and sales initiatives such as realigning our development and marketing organizations, and expanding our portfolio of suites and our offering of software as a service, and realigning our internal resources in an effort to improve efficiency. We may take such actions without clear indications that they will prove successful, and at times, we have been met with short-term challenges in the execution of such initiatives. Market acceptance of any new business or sales initiative is dependent on our ability to match our customers' needs at the right time and price. Often we have limited prior experience and operating history in these new areas of emphasis. If any of our assumptions about expenses, revenue or revenue recognition principles from these initiatives proves incorrect, or our attempts to improve efficiency are not successful, our actual results may vary materially from those anticipated, and our financial results will be negatively impacted.

2015 Form 10-K 23

Net revenue, billings, earnings or subscriptions shortfalls or the volatility of the market generally may cause the market price of our stock to decline.

The market price for our common stock has experienced significant fluctuations and may continue to fluctuate significantly. The market price for our common stock may be affected by a number of factors, including the other factors described in this Part I, Item 1A and the following:

• shortfalls in our expected financial results, including net revenue, billings, earnings, subscriptions, or other key performance metrics;

• results and future projections related to our business model transition, including the impact of the end of upgrades and perpetual licenses;

• quarterly variations in our or our competitors' results of operations;

• general socio-economic, political or market conditions;

• changes in estimates of future results or recommendations or confusion on the part of analysts and investors about the short-term and long-term impact to our business resulting from our business model transition;

• uncertainty about certain governments' abilities to repay debt or effect fiscal policy;

• the announcement of new products or product enhancements by us or our competitors;

• unusual events such as significant acquisitions, divestitures, regulatory actions, and litigation;

• changes in laws, rules, or regulations applicable to our business;

• outstanding debt service obligations; and

• other factors, including factors unrelated to our operating performance, such as instability affecting the economy or the operating performance of our competitors.

Significant changes in the price of our common stock could expose us to additional costly and time-consuming litigation. Historically, after periods of volatility in the market price of a company's securities, a company becomes more susceptible to securities class action litigation. This type of litigation is often expensive and diverts management's attention and resources.

Our business could be adversely affected if we are unable to attract and retain key personnel.

Our success and ability to invest and grow depend largely on our ability to attract and retain highly skilled technical, professional, managerial, sales, and marketing personnel. Historically, competition for these key personnel has been intense. The loss of services of any of our key personnel (including key personnel joining our company through acquisitions), the inability to retain and attract qualified personnel in the future, or delays in hiring required personnel, particularly engineering and sales personnel, could make it difficult to meet key objectives, such as timely and effective product introductions and financial goals.

2015 Form 10-K 24

Changes in laws and/or regulations related to the Internet or related to privacy and data security concerns may impact our business or expose us to increased liability.

The future success of our business depends upon the continued use of the Internet as a primary medium for commerce, communication, and business applications. Federal, state, or foreign government bodies or agencies have in the past adopted, and may in the future adopt, laws or regulations affecting data privacy and the transmission of certain types of content using the Internet. For example, the State of California has adopted legislation requiring operators of commercial websites and mobile applications that collect personal information from California residents to conspicuously post and comply with privacy policies that satisfy certain requirements. Several other U.S. states have adopted legislation requiring companies to protect the security of personal information that they collect from consumers over the Internet, and more states may adopt similar legislation in the future. Additionally, the Federal Trade Commission has used its authority under Section 5 of the Federal Trade Commission Act to bring actions against companies for failing to maintain adequate security for personal information collected from consumers over the Internet and for failing to comply with privacy-related representations made to Internet users. The U.S. Congress has at various times proposed federal legislation intended to protect the privacy of Internet users and the security of personal information collected from Internet users that would impose additional compliance burdens upon companies collecting personal information from Internet users, and the U.S. Congress may adopt such legislation in the future. The European Union also has adopted various directives regulating data privacy and security and the transmission of content using the Internet involving residents of the European Union, including those directives known as the Data Protection Directive, the E-Privacy Directive, and the Privacy and Electronic Communications Directive, and may adopt similar directives in the future. Several other countries, including Canada and several Latin American and Asian countries, have constitutional protections for, or have adopted legislation protecting, individuals' personal information. Additionally, some federal, state, or foreign governmental bodies have established laws that seek to censor the transmission of certain types of content over the Internet or require that individuals be provided with the ability to permanently delete all electronic personal information, such as the German Multimedia Law of 1997.

Given the variety of global privacy and data protection regimes, it is possible we may find ourselves subject to inconsistent obligations. For instance, the USA Patriot Act is considered by some to be in conflict with certain directives of the European Union. Situations such as these require that we make prospective determinations regarding compliance with conflicting regulations. Increased enforcement of existing laws and regulations, as well as any laws, regulations or changes that may be adopted or implemented in the future, could limit the growth of the use of public cloud applications or communications generally, result in a decline in the use of the Internet and the viability of Internet-based applications, and require implementation of additional technological safeguards.

Our investment portfolio consists of a variety of investment vehicles in a number of countries that are subject to interest rate trends, market volatility, and other economic factors. If general economic conditions decline, this could cause the credit ratings of our investments to deteriorate, illiquidity in the financial marketplace, and we may experience a decline in interest income, and an inability to sell our investments, leading to impairment in the value of our investments.

It is our policy to invest our cash, cash equivalents, and marketable securities in highly liquid instruments with, and in the custody of, financial institutions with high credit ratings and to limit the amounts invested with any one institution, type of security, and issuer. However, we are subject to general economic conditions, interest rate trends, and volatility in the financial marketplace that can affect the income that we receive from our investments, the net realizable value of our investments (including our cash, cash equivalents, and marketable securities) and our ability to sell them. In the U.S., for example, the yields on our portfolio securities are very low due to general economic conditions. Any one of these factors could reduce our investment income, or result in material charges, which in turn could impact our overall net income and earnings per share.

From time to time we make direct investments in privately held companies. The privately held companies in which we invest are considered inherently risky. The technologies and products these companies have under development are typically in the early stages and may never materialize, which could result in a loss of all or a substantial part of our initial investment in these companies. The evaluation of privately held companies is based on information that we request from these companies, which is not subject to the same disclosure regulations as U.S. publicly traded companies, and as such, the basis for these evaluations is subject to the timing and accuracy of the data received from these companies.

A loss on any of our investments may cause us to record an other-than-temporary impairment charge. The effect of this charge could impact our overall net income and earnings per share. In any of these scenarios, our liquidity may be negatively impacted, which in turn may prohibit us from making investments in our business, taking advantage of opportunities and potentially meeting our financial obligations as they come due.

2015 Form 10-K 25

We are subject to legal proceedings and regulatory inquiries, and we may be named in additional legal proceedings or become involved in regulatory inquiries in the future, all of which are costly, distracting to our core business and could result in an unfavorable outcome, or a material adverse effect on our business, financial condition, results of operations, cash flows or the trading price for our securities.

We are involved in legal proceedings and receive inquiries from regulatory agencies. As the global economy has changed and our business has evolved, we have seen an increase in litigation activity and regulatory inquiries. Like many other high technology companies, the number and frequency of inquiries from U.S. and foreign regulatory agencies we have received regarding our business and our business practices, and the business practices of others in our industry, have increased in recent years. In the event that we are involved in significant disputes or are the subject of a formal action by a regulatory agency, we could be exposed to costly and time consuming legal proceedings that could result in any number of outcomes. Any claims or regulatory actions initiated by or against us, whether successful or not, could result in expensive costs of defense, costly damage awards, injunctive relief, increased costs of business, fines or orders to change certain business practices, significant dedication of management time, diversion of significant operational resources, or otherwise harm our business. In any of these cases, our financial results could be negatively impacted.

Changes in existing financial accounting standards or practices, or taxation rules or practices may adversely affect our results of operations.

Changes in existing accounting or taxation rules or practices, new accounting pronouncements or taxation rules, or varying interpretations of current accounting pronouncements or taxation practice could have a significant adverse effect on our results of operations or the manner in which we conduct our business. Further, such changes could potentially affect our reporting of transactions completed before such changes are effective.

For example, the U.S.-based Financial Accounting Standards Board (“FASB”) is currently working together with the International Accounting Standards Board (“IASB”) on several projects to further align accounting principles and facilitate more comparable financial reporting between companies who are required to follow U.S. Generally Accepted Accounting Principles (“GAAP”) under SEC regulations and those who are required to follow IFRS outside of the U.S. These efforts by the FASB and IASB may result in different accounting principles under GAAP that may result in materially different financial results for us in areas including, but not limited to principles for recognizing revenue and lease accounting.

It is not clear if or when these potential changes in accounting principles may become effective, whether we have the proper systems and controls in place to accommodate such changes and the impact that any such changes may have on our consolidated financial position, results of operations and cash flows. In addition, as we evolve and change our business and sales models, we are currently unable to determine how these potential changes may impact our new models, particularly in the area of revenue recognition.

We regularly invest resources to update and improve our information technology systems. Should our investments not succeed, or if delays or other issues with new or existing internal technology systems disrupt our operations, our business could be harmed.

We rely on our network and data center infrastructure, technology systems and our websites for our development, marketing, operational, support, sales, accounting, and financial reporting activities. We are continually investing resources to update and improve these systems and environments in order to meet the growing and evolving requirements of our business and customers. Such improvements are often complex, costly, and time consuming. In addition, such improvements can be challenging to integrate with our existing technology systems, or uncover problems with our existing technology systems. Unsuccessful implementation of hardware or software updates and improvements could result in disruption in our business operations, loss of revenue, errors in our accounting and financial reporting, or damage to our reputation.

Although we believe we currently have adequate internal control over financial reporting, we are required to evaluate our internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act of 2002 and any adverse results from such evaluation could result in a loss of investor confidence in our financial reports and have an adverse effect on our stock price.

Pursuant to Section 404, we are required to furnish a report by our management on our internal control over financial reporting. The report contains, among other matters, an assessment of the effectiveness of our internal control over financial reporting as of the end of our fiscal year, including a statement as to whether or not our internal control over financial reporting

2015 Form 10-K 26

is effective. This assessment must include disclosure of any material weaknesses in our internal control over financial reporting identified by management.

If our management identifies one or more material weaknesses in our internal control over financial reporting and such weakness remains uncorrected at fiscal year-end, we will be unable to assert such internal control is effective at fiscal year-end. If we are unable to assert that our internal control over financial reporting is effective at fiscal year-end (or if our independent registered public accounting firm is unable to express an opinion on the effectiveness of our internal controls or concludes that we have a material weakness in our internal controls), we could lose investor confidence in the accuracy and completeness of our financial reports, which would likely have an adverse effect on our business and stock price.

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, and the fair value of stock awards. We also make assumptions, judgments, and estimates in determining the accruals for employee related liabilities including commissions, bonuses, and sabbaticals; and in determining the accruals for uncertain tax positions, partner incentive programs, product returns reserves, allowances for doubtful accounts, asset retirement obligations, 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.

Our financial results could be negatively impacted if our tax positions are overturned by tax authorities.

We are a U.S.-based multinational company subject to tax in multiple U.S. and foreign tax jurisdictions. Our effective tax rate is based on our expected geographic mix of earnings, statutory rates, intercompany transfer pricing, and enacted tax rules. Significant judgment is required in determining our effective tax rate and in evaluating our tax positions on a worldwide basis. We believe our tax positions, including intercompany transfer pricing policies, are consistent with the tax laws in the jurisdictions in which we conduct our business. It is possible that these positions may be overturned by jurisdictional tax authorities and may have a significant impact on our effective tax rate.

We rely on third-party technologies and if we are unable to use or integrate these technologies, our product and service development may be delayed and our financial results negatively impacted.

We rely on certain software that we license from third parties, including software that is integrated with internally developed software and used in our products to perform key functions. These third-party software licenses may not continue to be available on commercially reasonable terms, and the software may not be appropriately supported, maintained or enhanced by the licensors. The loss of licenses to, or inability to support, maintain, and enhance any such software could result in increased costs, or in delays or reductions in product shipments until equivalent software can be developed, identified, licensed, and integrated, which would likely harm our business.

Disruptions with licensing relationships and third-party developers could adversely impact our business.

We license certain key technologies from third parties. Licenses may be restricted in the term or the use of such technology in ways that negatively affect our business. Similarly, we may not be able to obtain or renew license agreements for key technology on favorable terms, if at all, and any failure to do so could harm our business.

Our business strategy has historically depended in part on our relationships with third-party developers who provide products that expand the functionality of our design software. Some developers may elect to support other products or may experience disruption in product development and delivery cycles or financial pressure during periods of economic downturn. In particular markets, such disruptions have in the past, and would likely in the future, negatively impact these third-party developers and end users, which could harm our business.

Additionally, technology created by outsourced product development, whether outsourced to third parties or developed externally and transferred to us through business or technology acquisitions, have certain additional risks such as effective integration into existing products, adequate transfer of technology know-how, and ownership and protection of transferred intellectual property.

2015 Form 10-K 27

As a result of our strategy of partnering with other companies for product development, our product delivery schedules could be adversely affected if we experience difficulties with our product development partners.

We partner with certain independent firms and contractors to perform some of our product development activities. We believe our partnering strategy allows us to, among other things, achieve efficiencies in developing new products and maintaining and enhancing existing product offerings. Our partnering strategy creates a dependency on such independent developers. Independent developers, including those who currently develop products for us in the U.S. and throughout the world, may not be able or willing to provide development support to us in the future. In addition, use of development resources through consulting relationships, particularly in non-U.S. jurisdictions with developing legal systems, may be adversely impacted by, and expose us to risks relating to, evolving employment, export, and intellectual property laws. These risks could, among other things, expose our intellectual property to misappropriation and result in disruptions to product delivery schedules.

Our business may be significantly disrupted upon the occurrence of a catastrophic event.

Our business is highly automated and relies extensively on the availability of our network and data center infrastructure, our internal technology systems and our websites. We also rely on hosted computer services from third parties for services that we provide to our customers and computer operations for our internal use. The failure of our systems or hosted computer services due to a catastrophic event, such as an earthquake, fire, flood, tsunami, weather event, telecommunications failure, power failure, cyber attack, or war, could adversely impact our business, financial results, and financial condition. We have developed disaster recovery plans and maintain backup systems in order to reduce the potential impact of a catastrophic event, however there can be no assurance that these plans and systems would enable us to return to normal business operations. In addition, any such event could negatively impact a country or region in which we sell our products. This could in turn decrease that country's or region's demand for our products, thereby negatively impacting our financial results.

We issued $750.0 million aggregate principal amount of senior unsecured notes in a debt offering in December 2012 and have an existing $400.0 million revolving credit facility, and may incur other debt in the future, all of which may adversely affect our financial condition and future financial results.

In December 2012, we issued 1.95% notes due December 15, 2017 in an aggregate principal amount of $400.0 million and 3.6% notes due December 15, 2022 in an aggregate principal amount of $350.0 million. As the December 2017 and December 2022 debt matures, we will have to expend significant resources to either repay or refinance these notes. If we decide to refinance the notes, we may be required to do so on different or less favorable terms or we may be unable to refinance the notes at all, both of which may adversely affect our financial condition.

We also have a $400.0 million revolving credit facility. As of January 31, 2015, we had no outstanding borrowings on the line of credit. Although we have no current plans to borrow under this credit facility, we may use the proceeds of any future borrowing for general corporate purposes, or for future acquisitions or expansion of our business. Our existing and future levels of indebtedness may adversely affect our financial condition and future financial results by, among other things:

• increasing our vulnerability to adverse changes in general economic, industry and competitive conditions;

• requiring the dedication of a greater than expected portion of our expected cash from operations to service our indebtedness, thereby reducing the amount of expected cash flow available for other purposes, including capital expenditures and acquisitions; and

• limiting our flexibility in planning for, or reacting to, changes in our business and our industry.

We are required to comply with the covenants set forth in our senior unsecured notes and revolving credit facility. Our ability to comply with these covenants may be affected by events beyond our control. If we breach any of the covenants and do not obtain a waiver from the note holders or lenders, then, subject to applicable cure periods, any outstanding indebtedness may be declared immediately due and payable. In addition, changes by any rating agency to our credit rating may negatively impact the value and liquidity of our securities. Under certain circumstances, if our credit ratings are downgraded or other negative action is taken, the interest rate payable by us under our revolving credit facility could increase. Downgrades in our credit ratings could also restrict our ability to obtain additional financing in the future and could affect the terms of any such financing.

ITEM 2. PROPERTIES

We lease 1,873,000 square feet of office space in 142 locations in the United States and internationally through our foreign subsidiaries. In addition, we own 107,000 square feet of office space in six locations internationally through our foreign subsidiaries. Our executive offices and corporate headquarters are located in leased office space in San Rafael, California. Our San Rafael facilities consist of 220,000 square feet under leases that have expiration dates ranging from December 2017 to December 2019. We and our foreign subsidiaries lease additional space in various locations throughout the world for local sales, product development, and technical support personnel.

All facilities are in good condition. Our facilities, excluding those in restructuring, are operating at capacities averaging 80% occupancy worldwide as of January 31, 2015. We believe that our existing facilities and offices are adequate to meet our requirements for the foreseeable future. See Note 8, “Commitments and Contingencies,” in the Notes to Consolidated Financial Statements for more information about our lease commitments.

ITEM 3. LEGAL PROCEEDINGS

We are involved in a variety of claims, suits, investigations, and proceedings in the normal course of business activities including claims of alleged infringement of intellectual property rights, commercial, employment, piracy prosecution, business practices, and other matters. In our opinion, resolution of pending matters is not expected to have a material adverse impact on our consolidated results of operations, cash flows, or financial position. Given the unpredictable nature of legal proceedings, there is a reasonable possibility that an unfavorable resolution of one or more such proceedings could in the future materially affect our results of operations, cash flows, or financial position in a particular period, however, based on the information known by us as of the date of this filing and the rules and regulations applicable to the preparation of our financial statements, any such amount is either immaterial or it is not possible to provide an estimated amount of any such potential loss.

As of January 31, 2015, the number of common stockholders of record was 479. Because many of our shares of common stock are held by brokers or other institutions on behalf of stockholders, we are unable to estimate the total number of stockholders represented by the record holders.

Issuer Purchases of Equity Securities

Autodesk's stock repurchase program is largely to help offset the dilution from the issuance of stock under our employee stock plans and for such other purposes as may be in the interests of Autodesk and its stockholders, and has the effect of returning excess cash generated from our business to stockholders. The number of shares acquired and the timing of the purchases are based on several factors, including general market conditions, the volume of employee stock option exercises, stock issuance, the trading price of our common stock, cash on hand and available in the U.S., and company defined trading windows. During the three and twelve months ended January 31, 2015, we repurchased 1.1 million and 6.9 million shares, respectively, of our common stock. At January 31, 2015, 14.8 million shares remained available for repurchase under the repurchase program approved by the Board of Directors. This program does not have a fixed expiration date. See Note 9, “Stockholders' Equity,” in the Notes to Consolidated Financial Statements for further discussion.

Strategy

Autodesk’s vision is to help people imagine, design, and create a better world. We do this by developing software and services for the world’s designers, architects, engineers, digital artists, professionals, and non-professionals alike—the people who imagine, design, and create the world's products, buildings, infrastructure, films, and games. Autodesk serves professional customers in three primary markets: architecture, engineering, and construction; manufacturing; and digital media and entertainment.

Our goal is to provide our customers with the world’s most innovative, and engaging design software and services. Our product and services portfolio allows our customers to digitally visualize, simulate, and analyze their projects, helping them to better understand the consequences of their design decisions; save time, money, and resources; and become more innovative.

Autodesk was founded during the platform transition from mainframes and engineering workstations to personal computers. We developed and sustained a compelling value proposition based upon desktop software for the personal computer. Just as the transition from mainframes to personal computers transformed the industry over 30 years ago, we believe our industry is undergoing a similar transition from the personal computer to cloud, social, and mobile computing. To address this transition we have accelerated our move to the cloud and mobile devices and are offering more flexible licensing. For example, in fiscal 2014, we began offering Autodesk BIM 360, PLM 360, Sim 360, and Fusion 360, a few of our cloud based offerings, which provide tools, including social and mobile capabilities, to help streamline design, collaboration, and data management processes. We believe that customer adoption of these new offerings will continue to grow as customers across a range of industries begin to take advantage of the scalable computing power and flexibility provided through these new services.

Our strategy is to lead our customers and the industries they serve to the new cloud and mobile platforms. This entails both a technological shift and a business model shift. During fiscal 2014, we announced more flexible term-based license offerings, including term-based desktop subscriptions, for certain products. These offerings are designed to give our customers even more flexibility with how they use our products and service offerings and address new types of customers such as project-based users and small businesses. As part of this transition, we have discontinued upgrades effective March 6, 2015. On February 4, 2015, we also announced that new commercial seats of most standalone software products will be available only by desktop subscription beginning February 1, 2016.

2015 Form 10-K 34

Over the next three years, we expect to increase our subscription base and customer value, which we believe will help drive billings growth. During the transition, revenue, deferred revenue, operating margin, and earnings per share will be affected as more revenue is recognized ratably rather than up front and as new offerings bring a wider variety of price points.

For fiscal 2015, our billings increased 18%, as compared to the prior fiscal year. The difference between our 10% year-over-year growth in revenue and our 18% year-over-year growth in billings represents 8 percentage points from the increase in deferred revenue, primarily driven by an increase in subscription billings over the past fiscal year and the business model transition.

At January 31, 2015 and January 31, 2014, our total subscriptions were 2.23 million and 1.85 million, respectively. Subscription additions were led by maintenance subscriptions and benefited from promotional activity driving upgrades and maintenance renewals.

For the past three years, suites have been an important growth area to our overall strategy. As our customers in all industries adopt our design suites, we believe they will experience an increase in their productivity and the value of their design data. For fiscal 2015, revenue from suites increased17%, as compared to the prior fiscal year. As a percentage of revenue, suites increased to 36% in fiscal 2015 as compared to 34% in fiscal 2014.

Another key element of our growth strategy is increasing our global penetration. Much of the growth in the world’s construction and manufacturing is happening in emerging economies. Further, emerging economies face many of the challenges that our design technology can help address, including infrastructure build-out and innovative design and manufacturing. In fiscal 2015, revenue from emerging economies increased14% as compared to fiscal 2014 and represented 15% of net revenue for both fiscal 2015 and fiscal 2014. While we continue to believe there are long-term growth opportunities in emerging economies, conducting business in these countries presents significant challenges, including economic volatility, geopolitical risk, local competition, limited intellectual property protection, poorly developed business infrastructure, scarcity of talent, software piracy, and different purchase patterns as compared to the developed world.

Today, complex challenges such as globalization, urbanization, and sustainable design are driving our customers to new levels of performance and competitiveness, and we are committed to helping them address those challenges and take advantage of new opportunities. To achieve these goals, we are capitalizing on two of our strongest competitive advantages: our ability to bring advanced technology to mainstream markets, and the breadth and depth of our product portfolio.

We bring powerful new design capabilities to volume markets. Our products are designed to be easy-to-learn and use, and to provide customers with a low cost of deployment, a low total cost of access to our software offerings, and a rapid return on investment. In addition, our software architecture allows for extensibility and integration with other products. The breadth of our technology and product line gives us a unique competitive advantage, because it allows our customers to address a wide variety of problems in ways that transcend industry and disciplinary boundaries. This is particularly important in helping our customers address the complex challenges mentioned above. We also believe that our technological leadership and global brand recognition have positioned us well for long-term growth and industry leadership.

In addition to the competitive advantages afforded by our technology, our large global network of distributors, resellers, third-party developers, customers, educational institutions, educators, and students is a key competitive advantage. This network of partners and relationships provides us with a broad and deep reach into volume markets around the world. Our distributor and reseller network is extensive and provides our customers with the resources to purchase, deploy, learn, and support our products quickly and easily. We have a significant number of registered third-party developers who create products that work well with our products and extend them for a variety of specialized applications.

Autodesk is committed to helping fuel a lifelong passion for design in students of all ages. In fiscal 2014, we initiated a new program offering free educational licenses of Autodesk software worldwide to students, educators, and educational institutions.  Targeting both the secondary and postsecondary school markets, we collaborate with educators, institutions and partners that encourage design learning and further Science, Technology, Engineering, Digital Arts, and Math (STEAM) education initiatives.   Our intention is to make Autodesk software the ubiquitous design software of choice for those poised to become the next generation of professional users.

Our strategy includes improving our product functionality and expanding our product offerings through internal development as well as through the acquisition of products, technology, and businesses. Acquisitions often increase the speed at which we can deliver product functionality to our customers; however, they entail cost and integration challenges and may, in certain instances, negatively impact our operating margins. We continually review these trade-offs in making decisions

2015 Form 10-K 35

regarding acquisitions. We currently anticipate that we will continue to acquire products, technology, and businesses as compelling opportunities become available.

Our strategy depends upon a number of assumptions to successfully make the transition toward new cloud and mobile platforms, including the related technology and business model shifts; making our technology available to mainstream markets; leveraging our large global network of distributors, resellers, third-party developers, customers, educational institutions, and students; improving the performance and functionality of our products; and adequately protecting our intellectual property. If the outcome of any of these assumptions differs from our expectations, we may not be able to implement our strategy, which could potentially adversely affect our business. For further discussion regarding these and related risks see Part I, Item 1A, “Risk Factors.”

Critical Accounting Policies and Estimates

Our Consolidated Financial Statements are prepared in conformity with U.S. generally accepted accounting principles. In preparing our Consolidated Financial Statements, we make assumptions, judgments, and estimates that can have a significant impact on amounts reported in our Consolidated Financial Statements. We base our assumptions, judgments, and estimates on historical experience and various other factors that we believe to be reasonable under the circumstances. Actual results could differ materially from these estimates under different assumptions or conditions. We regularly reevaluate our assumptions, judgments, and estimates. Our significant accounting policies are described in Note 1, “Business and Summary of Significant Accounting Policies,” in the Notes to Consolidated Financial Statements. We believe that of all our significant accounting policies, the following policies involve a higher degree of judgment and complexity. Accordingly, these are the policies we believe are the most critical to aid in fully understanding and evaluating our financial condition and results of operations.

Revenue Recognition.    We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed or determinable, and collection is probable. However, determining whether and when some of these criteria have been satisfied often involves assumptions and judgments that can have a significant impact on the timing and amount of revenue we report.

For multiple element arrangements containing only software and software-related elements, we allocate the sales price among each of the deliverables using the residual method, under which revenue is allocated to undelivered elements based on our vendor-specific objective evidence (“VSOE”) of fair value. VSOE is the price charged when an element is sold separately or a price set by management with the relevant authority. If we do not have VSOE of an undelivered software license, we defer revenue recognition on the entire sales arrangement until all elements for which we do not have VSOE are delivered. If we do not have VSOE for undelivered maintenance or services, the revenue for the arrangement is recognized over the longest contractual service period in the arrangement. We are required to exercise judgment in determining whether VSOE exists for each undelivered element based on whether our pricing for these elements is sufficiently consistent.

For multiple elements arrangements involving non-software elements, including cloud subscription services, our revenue recognition policy is based upon the accounting guidance contained in ASC 605, Revenue Recognition. For these arrangements, we first allocate the total arrangement consideration based on the relative selling prices of the software group of elements as a whole and to the non-software elements. We then further allocate consideration within the software group to the respective elements within that group using the residual method as described above. We exercise judgment and use estimates in connection with the determination of the amount of revenue to be recognized in each accounting period.

We allocate the total arrangement consideration among the various elements based on a selling price hierarchy. The selling price for a deliverable is based on its VSOE if available, third-party evidence ("TPE") if VSOE is not available, or the best estimated selling price ("BESP") if neither VSOE nor TPE is available. BESP represents the price at which Autodesk would transact for the deliverable if it were sold regularly on a standalone basis. To establish BESP for those elements for which neither VSOE nor TPE are available, we perform a quantitative analysis of pricing data points for historical standalone transactions involving such elements for a twelve-month period. As part of this analysis, we monitor and evaluate the BESP against actual pricing to ensure that it continues to represent a reasonable estimate of the standalone selling price, considering several other external and internal factors including, but not limited to, pricing and discounting practices, contractually stated prices, the geographies in which we offer our products and services, and the type of customer (i.e. distributor, value-added reseller, and direct end user, among others). We analyze BESP at least annually or on a more frequent basis if a significant change in our business necessitates a more timely analysis or if we experience significant variances in our selling prices.

2015 Form 10-K 36

Our assessment of likelihood of collection is also a critical factor in determining the timing of revenue recognition. If we do not believe that collection is probable, the revenue will be deferred until the earlier of when collection is deemed probable or payment is received.

Our indirect channel model includes both a two-tiered distribution structure, where distributors sell to resellers, and a one-tiered structure where Autodesk sells directly to resellers. Our product license revenue from distributors and resellers are generally recognized at the time title to our product passes to the distributor, in a two-tiered structure, or reseller, in a one-tiered structure, provided all other criteria for revenue recognition are met. This policy is predicated on our ability to estimate sales returns, among other criteria. We are also required to evaluate whether our distributors and resellers have the ability to honor their commitment to make fixed or determinable payments, regardless of whether they collect payment from their customers. Our policy also presumes that we have no significant performance obligations in connection with the sale of our product licenses by our distributors and resellers to their customers. If we were to change any of these assumptions or judgments, it could cause a material increase or decrease in the amount of revenue that we report in a particular period.

As part of the indirect channel model, Autodesk has a partner incentive program that uses quarterly attainment monetary rewards to motivate distributors and resellers to achieve mutually agreed upon business goals in a specified time period. A portion of these incentives reduce license and other revenue in the current period. The remainder, which relates to incentives on our Subscription Program, is recorded as a reduction to deferred revenue in the period the maintenance transaction is billed and subsequently recognized as a reduction to maintenance revenue over the contract period. These incentive balances do not require significant assumptions or judgments. The reserves associated with the partner incentive program are treated on the balance sheet as either contra account receivable (when due to distributors and direct resellers) or accounts payable (when due to indirect resellers).

Marketable Securities.     As described in Note 2, “Financial Instruments,” in the Notes to the Consolidated Financial Statements, our investments in marketable securities are measured at the end of each reporting period and reported at fair value. Fair value is defined as the price that would be received from the sale of an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. In determining the fair value of our investments we are sometimes required to use various alternative valuation techniques. Inputs to valuation techniques are either observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. These two types of inputs have created the following fair value hierarchy:

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

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

• Level 3 - Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

This hierarchy requires us to minimize the use of unobservable inputs and to use observable market data, if available, when determining fair value. This is generally true for our cash and cash equivalents and the majority of our marketable securities, which we consider to be Level 1 assets and Level 2 assets. However, determining the fair value of marketable securities when observable inputs are not available (Level 3) requires significant judgment. For example, we use probability weighted discounted cash flow models, in which some of the inputs are unobservable in the market, to estimate the fair value of our convertible debt securities. These assumptions are inherently subjective and involve significant management judgment. Whenever possible, we use observable market data and rely on unobservable inputs only when observable market data is not available, when determining fair value.

All of Autodesk’s marketable securities are subject to a periodic impairment review. We recognize an impairment charge when a decline in the fair value of its investments below the cost basis is judged to be other-than-temporary. Autodesk considers various factors in determining whether to recognize an impairment charge, including the length of time and extent to which the fair value has been less than Autodesk’s cost basis, the financial condition and near-term prospects of the investee, and Autodesk’s intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery in the market value.

2015 Form 10-K 37

Business Combinations.     We allocate the fair value of the consideration transferred to the assets and liabilities acquired, as well as to in-process research and development based on their estimated fair values at the acquisition date. Any residual purchase price is recorded as goodwill. The purchase price allocation requires us to make significant estimates and assumptions, especially at the acquisition date with respect to intangible assets and deferred revenue obligations.

Although we believe the assumptions and estimates we have made are reasonable, they are based in part on historical experience and information obtained from the management of the acquired companies and are inherently uncertain. Examples of critical estimates used in valuing certain of the intangible assets we have acquired or may acquire in the future include but are not limited to:

• future expected cash flows from sales, maintenance agreements, and acquired developed technologies;

• the acquired company’s trade name and customer relationships as well as assumptions about the period of time the acquired trade name and customer relationships will continue to be used in the combined company’s product portfolio;

• expected costs to develop the in-process research and development into commercially viable products and estimated cash flows from the projects when completed; and

• discount rates used to determine the present value of estimated future cash flows.

These estimates are inherently uncertain and unpredictable, and if different estimates were used the purchase price for the acquisition could be allocated to the acquired assets and liabilities differently from the allocation that we have made. In addition, unanticipated events and circumstances may occur which may affect the accuracy or validity of such estimates, and if such events occur we may be required to record a charge against the value ascribed to an acquired asset or an increase in the amounts recorded for assumed liabilities.

Goodwill.     When we acquire a business, a portion of the consideration transferred is typically allocated to acquired technology and other identifiable intangible assets, such as customer relationships and developed technology. The excess of the consideration transferred over the net of the acquisition-date fair value of identifiable assets acquired and liabilities assumed is recorded as goodwill. The amounts allocated to acquired technology and other intangible assets represent our estimates of their fair values at the acquisition date. We amortize the acquired technology and other intangible assets with finite lives over their estimated useful lives. The estimation of acquisition-date fair values of intangible assets and their useful lives requires us to make assumptions and judgments, including but not limited to an evaluation of macroeconomic conditions as they relate to our business, industry and market trends, projections of future cash flows, and appropriate discount rates.

We test goodwill for impairment annually in our fourth fiscal quarter or sooner should events or changes in circumstances indicate potential impairment. An optional assessment of qualitative factors of impairment (“optional assessment”) can be utilized prior to necessitating a two-step quantitative impairment test. Should the optional assessment be utilized for any given fiscal year, qualitative factors to consider include cost factors; financial performance; legal, regulatory, contractual, political, business, or other factors; entity specific factors; industry and market considerations, macroeconomic conditions, and other relevant events and factors affecting the reporting unit. If, after assessing the totality of events or circumstances, it is more likely than not that the fair value of the reporting unit is greater than its carrying value, then performing the two-step impairment test is unnecessary.

Under the two-step quantitative impairment test, we use discounted cash flow models that include assumptions regarding projected cash flows. Variances in these assumptions could have a significant impact on our conclusion as to whether goodwill is impaired, or the amount of any impairment charge. Impairment charges, if any, result from instances where the fair values of net assets associated with goodwill are less than their carrying values. As changes in business conditions and our assumptions occur, we may be required to record impairment charges.

For our annual impairment assessment in fiscal 2015, we utilized the optional assessment for Delcam, which has been deemed a separate reporting unit within our Manufacturing ("MFG") operating segment. Based on a review of the qualitative factors described above, we determined that for our Delcam reporting unit it was more likely than not that the fair value of the reporting unit exceeded the carrying value. As a result, we concluded that performing the two-step impairment test was not necessary for Delcam.

We used the quantitative two-step impairment test for each of our remaining reporting units: Platform Solutions and Emerging Business (“PSEB”), MFG, Architecture, Engineering, and Construction ("AEC"), and Media and Entertainment

2015 Form 10-K 38

(“M&E”). When applying the quantitative two-step impairment test, a discounted cash flow model was used, which included assumptions regarding projected cash flows. Based on this testing, we determined that the fair value was substantially in excess of the carrying value for each of the four reporting units and therefore the goodwill of each reporting unit was not impaired during the fiscal year ended January 31, 2015.

Realizability of Long-Lived Assets.     We assess the realizability of our long-lived assets and related intangible assets, other than goodwill, annually during the fourth fiscal quarter, or sooner should events or changes in circumstances indicate the carrying values of such assets may not be recoverable. We consider the following factors important in determining when to perform an impairment review: significant under-performance of a business or product line relative to budget; shifts in business strategies which affect the continued uses of the assets; significant negative industry or economic trends; and the results of past impairment reviews. When such events or changes in circumstances occur, we assess recoverability of these assets. 

We assessrecoverability of these assets by comparing the carrying amounts to the future undiscounted cash flows the assets are expected to generate. If impairment indicators were present based on our undiscounted cash flow models, which include assumptions regarding projected cash flows, we would perform a discounted cash flow analysis to assess impairments on long-lived assets. Variances in these assumptions could have a significant impact on our conclusion as to whether an asset is impaired or the amount of any impairment charge. Impairment charges, if any, result in situations where any fair values of these assets are less than their carrying values.

In addition to our recoverability assessments, we routinely review the remaining estimated useful lives of our long-lived assets. Any reduction in the useful life assumption will result in increased depreciation and amortization expense in the quarter when such determinations are made, as well as in subsequent quarters.

We will continue to evaluate the values of our long-lived assets in accordance with applicable accounting rules. As changes in business conditions and our assumptions occur, we may be required to record impairment charges.

Income Taxes.     We have $185.1 million of net deferred tax assets as of January 31, 2015, primarily a result of tax credits, net operating losses, and timing differences for reserves, accrued liabilities, stock options, deferred revenue, purchased technologies, and capitalized intangibles, partially offset by the establishment of U.S. deferred tax liabilities on unremitted earnings from certain foreign subsidiaries, and valuation allowances against U.S. and foreign deferred tax assets. We perform a quarterly assessment of the recoverability of these net deferred tax assets and believe that we will generate sufficient future taxable income in appropriate tax jurisdictions to realize the net deferred tax assets. Our judgments regarding future profitability may change due to future market conditions and other factors, including intercompany transfer pricing adjustments. Any change in future profitability may require material adjustments to these net deferred tax assets, resulting in a reduction in net income in the period when such determination is made. We believe our tax positions, including intercompany transfer pricing policies, are consistent with the tax laws in the jurisdictions in which we conduct our business. It is possible that these positions may be challenged by jurisdictional tax authorities and may have a significant impact on our effective tax rate.

Stock-Based Compensation.     We measure stock-based compensation cost at the grant date fair value of the award, and recognize expense ratably over the requisite service period, which is generally the vesting period. We estimate the fair value of certain stock-based payment awards (including grants of stock options and employee stock purchases related to the employee stock purchase plan) using either the Black-Scholes-Merton option-pricing model or a binomial-lattice model (e.g., Monte Carlo simulation model). To determine the grant-date fair value of our stock-based payment awards, we use a Black-Scholes model or the quoted stock price on the date of grant, unless the awards are subject to market conditions, in which case we use the Monte Carlo simulation model. The Monte Carlo simulation model utilizes multiple input variables to estimate the probability that market conditions will be achieved. These variables include our expected stock price volatility over the expected term of the award, actual and projected employee stock option exercise behaviors, the risk-free interest rate for the expected term of the award, and expected dividends. The variables used in these models are reviewed on a quarterly basis and adjusted, as needed. Share-based compensation cost for restricted stock is measured on the closing fair market value of our common stock on the date of grant. The value of the portion of the award that is ultimately expected to vest is recognized as expense in our Consolidated Statements of Operations.

Legal Contingencies.     As described in Part I, Item 3, “Legal Proceedings” and Part II, Item 8, Note 8, “Commitments and Contingencies,” in the Notes to Consolidated Financial Statements, we are periodically involved in various legal claims and proceedings. We routinely review the status of each significant matter and assess our potential financial exposure. If the potential loss from any matter is considered probable and the amount can be reasonably estimated, we record a liability for the estimated loss. Because of inherent uncertainties related to these legal matters, we base our loss accruals on the best information

Overview of Fiscal 2015

	Fiscal Year Ended January 31, 2015		As a % of Net Revenue		Fiscal Year Ended January 31, 2014		As a % of Net Revenue
	(in millions)
Net Revenue	$	2,512.2	100	%	$	2,273.9	100	%
Cost of revenue	342.1		14	%	274.3		12	%
Gross Profit	2,170.1		86	%	1,999.6		88	%
Operating expenses	2,049.4		82	%	1,714.8		75	%
Income from Operations	$	120.7	5	%	$	284.8	13	%

During fiscal 2015, as compared to the prior fiscal year, net revenue increased10%, gross profit increased9%, and income from operations decreased58%. Contributing to the year over year decrease in income from operations during fiscal 2015 was an increase in operating expenses, offset by increases in both subscription revenue and license and other revenue.

We continue to make progress on our business model transition announced in fiscal 2014 with more flexible licenses and service offerings that have ratable revenue streams. As a result, our net revenue for fiscal 2015 excluded approximately $87 million that was deferred as a result of the transition. The $87 million related to flexible licensing arrangements with certain enterprise customers and had a particular impact on license revenue in the Americas and EMEA geographies, as well as our AEC and MFG business segments.

Our business experienced year over year growth in our AEC, MFG, and PSEB segments, many of our major products, particularly our AEC suites, and all of our geographic areas, particularly EMEA. This growth contributed to the year over year increase in both subscription and license and other revenue during fiscal 2015. We also experienced growth in our total subscriptions and billings during fiscal 2015, as compared to fiscal 2014, primarily due to promotional activity driving upgrades and maintenance renewals in advance of the end of upgrades after fiscal 2015.

Income from operations for fiscal 2015 was negatively impacted by increased spend as a result of the business model transition, the incremental employee costs associated with acquisitions, investments in our move to the cloud, as well as increased spending on other key initiatives.

The reasons for these changes are discussed below under the heading “Results from Operations.”

Revenue Analysis

Revenue from flagship products represented 48% and 51% of total net revenue during fiscal 2015 and fiscal 2014, respectively. Revenue from flagship products increased by 2% as compared to the prior fiscal year. Revenue from suites represented 36% and 34% of total net revenue for fiscal 2015 and fiscal 2014, respectively, and increased by 17% compared to the prior fiscal year. Revenue from new and adjacent products represented 16% and 14% of total net revenue during fiscal 2015 and fiscal 2014, respectively. Revenue from new and adjacent products increased by 24% as compared to fiscal 2014.

We rely significantly upon major distributors and resellers in both the U.S. and international regions, including Tech Data Corporation and its global affiliates (collectively, “Tech Data”). Tech Data accounted for 25% and 24% of our consolidated net revenue during fiscal 2015 and 2014, respectively. We believe our business is not substantially dependent on Tech Data. Our customers through Tech Data are the resellers and end users who purchase our software licenses and services. Should any of the agreements between Tech Data and us be terminated for any reason, we believe the resellers and end users who currently

2015 Form 10-K 40

purchase our products through Tech Data would be able to continue to do so under substantially the same terms from one of our many other distributors without substantial disruption to our revenue.

Operating Margin Analysis

Income from operations decreased58% in fiscal 2015 due to a $334.6 million or 20% increase in our operating expenses and a $67.8 million or 25% increase in cost of revenue, as compared to fiscal 2014. Partially offsetting the increase in our spend was a $238.3 million or 10% increase in net revenue, as compared to the prior fiscal year. Our operating margin decreased to 5% for fiscal 2015 from 13% for fiscal 2014. The increase in cost of revenue was driven by employee related expenses associated with the business model transition as well as the inclusion of Delcam related costs and an increase in cloud service costs as compared to the prior fiscal year. The increase in operating expenses between fiscal 2015 and 2014 was driven by higher employee related costs, primarily due to increased headcount and higher commissions expense as a result of increased billings. Also impacting the increase in operating expenses during fiscal 2015 as compared to fiscal 2014 was an increase in professional fees related to acquisition and business model transition initiatives.

Further discussion regarding the cost of revenue and operating expense activities are discussed below under the heading “Results of Operations.”

Foreign Currency Analysis

We generate a significant amount of our revenue in the U.S., Japan, Germany, France, and the United Kingdom. Total net revenue for fiscal 2015increased10% on an as reported basis compared to the prior fiscal year, and was negatively impacted by foreign exchange rate changes during fiscal 2015. Had applicable exchange rates from fiscal 2014 been in effect during fiscal 2015 and had we excluded foreign exchange hedge gains and losses from both fiscal 2014 and 2015 (“on a constant currency basis”), net revenue would have increased12% compared to the prior fiscal year.

Our total spend, defined as cost of revenue plus operating expenses, during fiscal 2015increased20% on an as reported basis as compared to the prior fiscal year. Had applicable exchange rates from fiscal 2014 been in effect during fiscal 2015 and had we excluded foreign exchange hedge gains and losses from both fiscal 2014 and 2015, total spend would have increased21% on a constant currency basis compared to the prior fiscal year.

Changes in the value of the U.S. dollar may have a significant effect on net revenue, total spend, and income from operations in future periods. We use foreign currency contracts to reduce the exchange rate effect on a portion of the net revenue of certain anticipated transactions but do not attempt to completely mitigate the impact of fluctuations of such foreign currency against the U.S. dollar.

Balance Sheet and Cash Flow Items

At January 31, 2015, we had $2,299.4 million in cash and marketable securities. We completed fiscal 2015 with higher deferred revenue and accounts receivable balances as compared to the prior fiscal year. Our deferred revenue balance at January 31, 2015 included $936.8 million of deferred subscription revenue primarily related to customer maintenance contracts, which will be recognized as revenue ratably over the life of the contracts. The term of our maintenance contracts is typically between one and three years. Our cash flow from operations increased26% to $708.1 million as of January 31, 2015 from $563.5 million at January 31, 2014. We repurchased 6.9 million shares of our common stock for $372.4 million during fiscal 2015. Comparatively, we repurchased 10.5 million shares of our common stock for $423.8 million during fiscal 2014. Further discussion regarding the balance sheet and cash flow activities are discussed below under the heading “Liquidity and Capital Resources.”

Business Outlook

Autodesk's business model is evolving. We continue to assess current business offerings including introducing more flexible license and service offerings that have ratable revenue streams. The accounting impact of these offerings and other business decisions are expected to result in an increase in the percentage of our ratable revenue, making for a more predictable business over time, while correspondingly reducing our upfront perpetual revenue stream. Over time, we expect our business model transition to expand our customer base by eliminating higher up-front licensing costs and providing more flexibility in how customers gain access to and pay for our products. We also expect our traditional perpetual license revenue to decline without a corresponding decrease in expenses over the next 12 to 24 months. In the future, we expect this business model transition will increase our long-term revenue growth rate by increasing total subscriptions and customer value over time.

2015 Form 10-K 41

We expect net revenue for the first quarter of fiscal 2016 will range from $625 million to $645 million, and that GAAP diluted earnings per share will range from $0.01 to $0.06 while non-GAAP diluted earnings per share will range from $0.25 to $0.30. Non-GAAP earnings per diluted share exclude $0.16 related to stock-based compensation expense and $0.08 related to the amortization of acquisition related intangibles, net of tax.

We expect net billings for fiscal 2016 to increase by approximately 3% to 5% compared to fiscal 2015. We expect net revenue for fiscal 2016 to increase by approximately 3% to 5% compared to fiscal 2015, and that GAAP diluted earnings per share will range from $0.10 to $0.25 while non-GAAP diluted earnings per share will range from $1.05 to $1.20. Non-GAAP earnings per diluted share exclude $0.70 related to stock-based compensation expense and $0.25 related to the amortization of acquisition related intangibles, net of tax. Autodesk anticipates fiscal 2016 GAAP operating margin to be approximately 2% to 4% and non-GAAP operating margin to be approximately 13% to 15%.  The non-GAAP operating margin excludes 8 percentage points related to stock-based compensation expense and 3 percentage points related to the amortization of acquisition related intangibles, net of tax. Autodesk expects to add approximately 375,000 to 425,000 net new subscriptions in fiscal 2016.

We remain diligent about managing our spend while making essential investments to drive growth. If we are unable to successfully achieve our major business initiatives we may not achieve our financial goals.

Fiscal 2015 Net Revenue Compared to Fiscal 2014 Net Revenue

Certain prior period balances have been updated to conform with current period presentation.

License and Other Revenue

License and other revenue consists of two components: (1) all forms of product license revenue and (2) other revenue. Product license revenue includes software license revenue from the sale of seat licenses, term-based licenses from our desktop subscription and enterprise offerings, and product revenue for Creative Finishing. Other revenue includes revenue from consulting, training, Autodesk Developers Network, and Creative Finishing customer support, and is recognized as the services are performed.

2015 Form 10-K 42

Total License and other revenue increased7% during fiscal 2015 as compared to fiscal 2014. This increase was primarily due to a 7% increase in product license revenue as compared to the same period in the prior fiscal year. The increase in product license revenue was primarily due to an 8% increase in suites revenue and an increase of 4% in revenue from our flagship products.

During fiscal 2015, the 7% increase in product license revenue was due to a 7%increase in the average net revenue per seat while the number of seats sold remained flat compared to the prior fiscal year. Product license revenue, as a percentage of License and other revenue, was 89% for both fiscal 2015 and fiscal 2014.

During fiscal 2015, total other revenue represented 11% of license and other revenue, and 6% of total net revenue. Other revenue increased by 7% during fiscal 2015 as compared to fiscal 2014. This increase is primarily due to a 17% increase in revenue from consulting, partially offset by a 65% decrease in revenue from our education products as a result of our strategic transition to offer free educational licenses of Autodesk software to students, educators, and institutions.

Backlog related to current software license product orders that had not shipped at the end of the fiscal year increased by $20.7 million from $19.7 million at January 31, 2014 to $40.4 million at January 31, 2015. Backlog from current software license product orders that we have not yet shipped consists of orders for currently available licensed software products from customers with approved credit status.

Subscription Revenue

Our Subscription revenue consists of three components: (1) maintenance revenue from our software products; (2)maintenance revenue from our term-based desktop subscription and enterprise offerings; and (3) revenue from our cloud service offerings. Our maintenance program provides our customers of software products with a cost effective and predictable budgetary option to obtain the productivity benefits of our new releases and enhancements when and if released during the term of their contracts. Under our maintenance program, customers are eligible to receive unspecified upgrades when and if available, downloadable training courses, and online support. We recognize maintenance revenue ratably over the term of the maintenance agreement, which is generally between one and three years. Revenue for our cloud service offerings is recognized ratably over the contract term commencing with the date our service is made available to customers and all other revenue recognition criteria have been satisfied.

Subscription revenue increased15% during fiscal 2015 as compared to fiscal 2014 primarily due to a 15%increase in commercial maintenance revenue. The 15%increase in commercial maintenance revenue was due to a 9%increase from net revenue per maintenance seat and a 6%increase from commercial enrollment during the corresponding maintenance contract term. Commercial maintenance revenue represented 96% and 95% of Subscription revenue for fiscal 2015 and fiscal 2014, respectively.

Changes in Subscription revenue lag changes in net billings for subscription contracts because we recognize the revenue from those contracts ratably over their contract terms. Net subscription billings increased22% during fiscal 2015 as compared to the prior fiscal year primarily due to an increase in maintenance subscription billings.

Our deferred subscription revenue balance at January 31, 2015 and January 31, 2014 was $936.8 million and $789.3 million, respectively, and primarily related to customer maintenance agreements, which will be recognized as revenue ratably over the term of the maintenance agreement.

Net Revenue by Geographic Area

Net revenue in the Americas geography increased by 10% as reported and on a constant currency basis during fiscal 2015, as compared to the prior fiscal year. This increase was primarily due to a 16%increase in our suites revenue and an 18%increase in our new and adjacent product revenue in this geography during fiscal 2015 as compared to fiscal 2014. The increase in this geography was led by the U.S.

Net revenue in the EMEA geography increased by 15% on an as reported basis and 13% on a constant currency basis during fiscal 2015 as compared to the prior fiscal year. This increase was primarily due to a 24%increase in our suites products and a 45%increase in our new and adjacent product revenue in this geography during fiscal 2015 as compared to fiscal 2014. The increase in our revenue in this geography was led by Germany and France.

2015 Form 10-K 43

Net revenue in the APAC geography increased5% on an as reported basis and 11% on a constant currency basis, during fiscal 2015 as compared to the prior fiscal year, primarily due to a 4%increase in our flagship products and a 5%increase in our suites products in this geography. Our revenue in this geography during fiscal 2015 benefited from increases in revenue from South Korea and India, partially offset by a decrease in revenue from Japan.

Net revenue in emerging economies increased14% during fiscal 2015 as compared to the prior fiscal year, primarily due to increases in revenue from India and Mexico. Revenue from emerging economies represented 15% of total net revenue for both fiscal 2015 and 2014.

International net revenue represented 71% and 70% of our total net revenue for fiscal 2015 and 2014, respectively. We believe that international revenue will continue to comprise a majority of our total net revenue. Unfavorable economic conditions in the countries that contribute a significant portion of our net revenue, including in emerging economies, may have an adverse effect on our business in those countries and our overall financial performance. Changes in the value of the U.S. dollar relative to other currencies have significantly affected, and could continue to significantly affect, our financial results for a given period even though we hedge a portion of our current and projected revenue. Additionally, weak global economic conditions that have been characterized by restructuring of sovereign debt, high unemployment, and volatility in the financial markets may impact our future financial results.

Net Revenue by Operating Segment

We have four reportable segments: AEC, PSEB, MFG, and M&E. We have no material inter-segment revenue.

Net revenue for AEC increased by 19% during fiscal 2015 as compared to the prior fiscal year primarily due to a 31% increase in revenue from our AEC suites, which was primarily driven by Autodesk Building Design Suite and Autodesk Infrastructure Design Suite.

Net revenue for PSEB increased by 1% during fiscal 2015 as compared to the prior fiscal year primarily due to a 3% increase in revenue from our flagship product AutoCAD LT. Revenue from AutoCAD remained flat in fiscal 2015 as compared to fiscal 2014.

Net revenue for MFG increased by 17% during fiscal 2015 as compared to the prior fiscal year primarily due to the acquisition of Delcam plc ("Delcam"). Also contributing to the increase in net revenue for MFG was a 9% increase in revenue from our MFG suites, which was primarily driven by the Autodesk Product Design Suite, as compared to fiscal 2014.

Net revenue for M&E decreased by 4% during fiscal 2015 as compared to the prior fiscal year, primarily due to an 11% decrease in revenue from Creative Finishing and a 2% decrease in revenue from Animation. The decline in Creative Finishing was marked by a general decrease in the M&E industry end-market demand, partially offset by a 33% increase in sales of our Creative Finishing hardware products. The decrease in Animation revenue was primarily due to a 20% decrease in revenue from our M&E suites, which was driven by our Autodesk Entertainment Creation Suite, partially offset by a 5% increase in our flagship product 3ds Max. M&E revenue is impacted by a general decrease in the M&E industry end-market demand, the planned inclusion of our M&E products in other Autodesk industry suites, and the business model transition as customers are opting for desktop subscription.

Fiscal 2014 Net Revenue Compared to Fiscal 2013 Net Revenue

This discussion has been updated to conform with current period's presentation.

License and Other Revenue

Total License and other revenue decreased 8% during fiscal 2014 as compared to fiscal 2013. This decrease was primarily due to a 7% decrease in product license revenue as compared to the same period in the prior fiscal year. The decline in product license revenue was primarily due to a decrease of 15% in revenue from our flagship products partially offset by an increase of 10% in our suites products.

During fiscal 2014, the 7% decrease in product license revenue was due to a 21% decrease in the number of seats sold partially offset by a 14% increase in the average net revenue per seat. Product license revenue, as a percentage of License and other revenue, was 89% for both fiscal 2014 and fiscal 2013.

2015 Form 10-K 44

During fiscal 2014, total other revenue represented 11% of License and other revenue. Other revenue decreased by 11% during fiscal 2014 as compared to fiscal 2013. This decrease is primarily due to a 56% decrease in our education products as a result of our transition to granting no or low-cost software licenses to educational institutions in select regions and to key partners during fiscal 2014, consistent with our strategy.

Backlog related to current software license product orders that had not shipped at the end of the fiscal year decreased by $0.3 million, from $20.0 million at January 31, 2013 to $19.7 million at January 31, 2014.

Subscription Revenue

Subscription revenue increased 7% during fiscal 2014 as compared to fiscal 2013 primarily due to a 9% increase in commercial maintenance revenue. The 9% increase in commercial maintenance revenue was due to a 4% increase from commercial enrollment during the corresponding maintenance contract term and a 5% increase from net revenue per maintenance seat. Commercial maintenance revenue represented 95% and 94% of Subscription revenue for fiscal 2014 and fiscal 2013, respectively.

Net subscription billings remained flat during fiscal 2014 as compared to the prior fiscal year primarily due to a decline in multi-year maintenance subscriptions partially offset by an increase in billings from suites, which have higher maintenance subscription prices.

Our deferred subscription revenue balance at January 31, 2014 and January 31, 2013 was $789.3 million and $753.1 million, respectively, and primarily related to customer maintenance agreements, which will be recognized as revenue ratably over the term of the maintenance agreement.

Net Revenue by Geographic Area

Net revenue in the Americas geography decreased by 2% as reported and on a constant currency basis during fiscal 2014, as compared to the prior fiscal year. This decrease was primarily due to a 13% decrease in our flagship product revenue partially offset by a 14% increase in our suites revenue in this geography during fiscal 2014 as compared to fiscal 2013. The decrease in our revenue in this geography was led by Canada and Brazil partially offset by an increase in revenue from the U.S.

Net revenue in the Europe, Middle East, and Africa ("EMEA") geography decreased by 2%, and remained flat on a constant currency basis, during fiscal 2014 as compared to the prior fiscal year. This decrease was primarily due to a 13% decrease in our flagship products partially offset by a 21% increase in our suites products in this geography during fiscal 2014 as compared to fiscal 2013. The decrease in our revenue in this geography was led by Ireland, Sweden, and the Netherlands partially offset by an increase in revenue from Finland and the United Kingdom.

Net revenue in the APAC geography decreased 1% and increased by 5% on a constant currency basis, during fiscal 2014 as compared to the prior fiscal year, primarily due to a 3% decrease in our flagship products partially offset by a 10% increase in our suites products in this geography. Our revenue in this geography during fiscal 2014 was impacted by decreases in revenue from Australia, Japan, and Taiwan, partially offset by an increase in revenue from China.

Net revenue in emerging economies remained flat during fiscal 2014 as compared to the prior fiscal year, primarily due to increases in revenue from Lebanon and China offset by a decrease in revenue from the Russian Federation. Revenue from emerging economies represented 15% and 14% of total net revenue for fiscal 2014 and 2013, respectively.

International net revenue represented 70% and 71% of our total net revenue for fiscal 2014 and 2013, respectively. We believe that international revenue will continue to comprise a majority of our total net revenue.

Net Revenue by Operating Segment

Net revenue for PSEB decreased by 6% during fiscal 2014 as compared to the prior fiscal year primarily due to a 9% and 4% decrease in revenue from our flagship products, AutoCAD and AutoCAD LT, respectively.

Net revenue for AEC increased by 4% during fiscal 2014 as compared to the prior fiscal year primarily due to a 31% increase in revenue from our AEC suites, which was primarily driven by Autodesk Building Design Suite and Autodesk Infrastructure Design Suite.

2015 Form 10-K 45

Net revenue for MFG increased by 1% during fiscal 2014 as compared to the prior fiscal year primarily due to a 9% increase in revenue from our MFG suites, which was primarily driven by the Autodesk Product Design Suite. This increase was partially offset by a decrease in revenue from our flagship product, AutoCAD Mechanical.

Net revenue for M&E decreased by 10% during fiscal 2014 as compared to the prior fiscal year, primarily due to a 7% decrease in revenue from Animation and a 17% decrease in revenue from Creative Finishing. The decrease in Animation revenue was primarily due to a 9% decrease in revenue from our flagship product, Maya, and a 16% decrease from our M&E suites, which was driven by our Autodesk Entertainment Creation Suite. The decline in Creative Finishing was marked by a general decrease in M&E industry end-market demand.

As a percentage of net revenue	14		%					12		%					10		%

Cost of license and other revenue includes labor costs associated with product setup and fulfillment and costs of fulfilling consulting and training services contracts and collaborative project management services contracts. Cost of license and other revenue also includes stock-based compensation expense, direct material and overhead charges, amortization of purchased technology, professional services fees and royalties. Direct material and overhead charges include the cost of hardware sold (mainly PC-based workstations for Creative Finishing in the M&E segment), costs associated with transferring our software to electronic media, physical media, packaging materials, and shipping and handling costs.

Cost of license and other revenue increased17% during fiscal 2015, as compared to fiscal 2014, primarily from the acquisition of Delcam and consulting support costs associated with an increased headcount and increased professional fees related to the building out of the consulting services offered within customer contracts. Cost of license and other revenue increased8% during fiscal 2014, as compared to fiscal 2013, primarily due to an increase in consulting support costs.

Cost of subscription revenue includes the labor costs of providing product support to our maintenance and cloud subscription customers, including rent and occupancy, shipping and handling costs, professional services fees related to operating our network infrastructure, including depreciation expense and operating lease payments associated with computer equipment, data center costs, salaries, and related expenses of network operations. Cost of subscription revenue increased40% during fiscal 2015 as compared to fiscal 2014 primarily due to higher employee-related costs as a result of increased premium support headcount as well as an increase in cloud services-related expenses. Cost of subscription revenue increased32% during fiscal 2014 as compared to fiscal 2013 primarily due to an increase in cloud services-related expenses.

Cost of revenue, at least over the near term, is affected by the volume and mix of product sales, mix of physical versus electronic fulfillment, fluctuations in consulting costs, amortization of purchased technology, new customer support offerings, royalty rates for licensed technology embedded in our products, and employee stock-based compensation expense.

We expect cost of revenue to increase in absolute dollars and slightly increase as a percentage of net revenue during fiscal 2016, as compared to fiscal 2015, primarily due to an increase in costs associated with meeting our major business initiatives.

Marketing and sales expenses include salaries, bonuses, benefits, and stock-based compensation expense for our marketing and sales employees, the expense of travel, entertainment and training for such personnel, the costs of programs aimed at increasing revenue, such as advertising, trade shows and expositions, and various sales and promotional programs. Marketing and sales expenses also include labor costs of sales and order processing, sales and dealer commissions, rent and occupancy, and the cost of supplies and equipment.

Marketing and sales expenses increased18% during fiscal 2015, as compared to fiscal 2014, primarily due to higher employee-related costs from salaries, commissions, and bonuses as well as advertising and promotional expenses. Marketing and sales expenses decreased4% during fiscal 2014, as compared to fiscal 2013, primarily due to lower advertising and promotional expenses and employee-related costs from salaries, bonuses, and commissions.

We expect to balance our need to invest in the marketing and sales of our products with our desire to actively manage our marketing and sales operating expenses. As a result, we expect marketing and sales expense to slightly increase in absolute dollars and slightly decrease as a percentage of net revenue in fiscal 2016 as compared to fiscal 2015 primarily due to an increase in costs as we work towards meeting our major business initiatives.

Research and Development

As a percentage of net revenue	29		%					27		%					26		%

Research and development expenses, which are expensed as incurred, consist primarily of salaries, bonuses, benefits, and stock-based compensation expense for research and development employees, and the expense of travel, entertainment and training for such personnel, rent and occupancy, and professional services such as fees paid to software development firms and independent contractors.

Research and development expenses increased19% during fiscal 2015, as compared to fiscal 2014, primarily due to an increase in employee-related costs from salaries and bonuses and an increase in professional fees. Research and development expenses increased2% during fiscal 2014, as compared to fiscal 2013, primarily due to an increase in employee-related costs from salaries and fringe benefits and an increase in professional fees partially offset by a decline in stock-based compensation expense due to a one-time charge associated with the acquisition of Socialcam in fiscal 2013.

We expect research and development expense to increase in absolute dollars but remain consistent as a percentage of net revenue during fiscal 2016, as compared to fiscal 2015, as we continue to invest in product development in fiscal 2016.

General and administrative expenses include salaries, bonuses, benefits, and stock-based compensation expense for our finance, human resources, and legal employees, as well as professional fees for legal and accounting services, gains and losses on our operating expense cash flow hedges, expense of travel, entertainment and training, expense of communication, and the cost of supplies and equipment.

General and administrative expenses increased34% from fiscal 2014 to fiscal 2015 primarily due to an increase in employee-related costs from salaries and bonuses and an increase in professional fees. General and administrative expenses increased3% from fiscal 2013 to fiscal 2014, primarily due to an increase in employee-related costs from salaries and fringe benefits in fiscal 2014.

We expect general and administrative expense to increase in absolute dollars and slightly increase as a percentage of net revenue during fiscal 2016, as compared to fiscal 2015, primarily due to an increase in costs associated with supporting our major business initiatives.

Amortization of purchased intangibles increased9% from fiscal 2014 to fiscal 2015, primarily related to the accumulated effects associated with amortization expense of intangible assets purchased over time, including $164.1 million in assets purchased in fiscal 2015 as compared to $40.3 million purchased in fiscal 2014.

Amortization of purchased intangibles decreased13% from fiscal 2013 to fiscal 2014, primarily related to the accumulated effects associated with amortization expense of intangible assets purchased over time, including $40.3 million in assets purchased in fiscal 2014 as compared to $76.9 million purchased in fiscal 2013.

We expect amortization of purchased intangibles expense to decrease in absolute dollars and slightly decrease as a percentage of net revenue during fiscal 2016, as compared to fiscal 2015.

During fiscal 2014, our Board of Directors approved a world-wide restructuring plan in order to re-balance staffing levels to better align them with the evolving needs of the business. During fiscal 2015, Autodesk recorded a restructuring charge of $3.1 million. Of this amount, $2.5 million was recorded for one-time termination benefits and other costs and $0.6 million was recorded for facilities-related costs.

During fiscal 2013, the our Board of Directors approved a world-wide restructuring plan in line with the Company's strategy, including its continuing shift to cloud and mobile computing. The approved plan included a reduction in force and the consolidation of certain leased facilities.

See Note 15, “Restructuring Reserves,” in Notes to Consolidated Financial Statements for further discussion.

Interest and Other (Expense) Income, Net

The following table sets forth the components of interest and other income, net:

	Fiscal Year Ended January 31,
	2015			2014			2013
	(in millions)
Interest and investment (expense) income, net	$	(13.2	)	$	(9.8	)	$	4.9
(Loss) gain on foreign currency	(3.9		)	4.0			1.2
Loss on strategic investments	(23.3		)	(1.8		)	(4.0		)
Other income	2.7			2.7			2.0
Interest and other (expense) income, net	$	(37.7	)	$	(4.9	)	$	4.1

Interest and other (expense) income, net, increased $32.8 million during fiscal 2015, as compared to fiscal 2014, primarily due to an increase in losses on our privately held strategic investments. The increase in the loss on strategic investments during fiscal 2015 as compared to fiscal 2014 is primarily due to other-than-temporary impairments on two of our privately held strategic investments and losses on the derivative portion of our strategic investments that are marked-to-market each period.

Interest and other (expense) income, net, decreased $9.0 million during fiscal 2014, as compared to fiscal 2013, primarily due to interest expense resulting from the December 2012 issuance of $400.0 million aggregate principal amount of 1.95% senior notes due December 15, 2017 and $350.0 million aggregate principal amount of 3.6% senior notes due December 15, 2022. Interest and investment income fluctuates based on average cash, marketable securities and debt balances, average maturities, and interest rates.

Provision for Income Taxes

We account for income taxes and the related accounts under the liability method. Deferred tax liabilities and assets are determined based on the difference between the financial statement and tax bases of assets and liabilities, using enacted rates expected to be in effect during the year in which the basis differences reverse.

Our effective tax rate was 1% and 18% during fiscal 2015 and fiscal 2014, respectively. Our effective tax rate decreased 17 percentage points from fiscal 2014 to fiscal 2015 due to an increase in tax benefits from foreign earnings taxed at different rates in fiscal 2015 compared to fiscal 2014 and increased benefit from research credits, offset in part by lower tax benefits from stock-based compensation.

2015 Form 10-K 49

Our effective tax rate was 18% and 20% during fiscal 2014 and 2013, respectively. Our effective tax rate decreased two percentage points from fiscal 2013 to fiscal 2014 primarily due to an increase in tax benefits from foreign earnings taxed at different rates in fiscal 2014 compared to fiscal 2013, offset in part by lower tax benefits from restructuring and additional tax expense associated with uncertain tax positions and audit assessments.

Our future effective tax rate may be materially impacted by the amount of benefits and charges from tax amounts associated with our foreign earnings that are taxed at rates different from the federal statutory rate, research credits, state income taxes, the tax impact of stock-based compensation, accounting for uncertain tax positions, business combinations, U.S. Manufacturer's deduction, closure of statute of limitations or settlement of tax audits, changes in valuation allowances and changes in tax laws including possible U.S. tax law changes that, if enacted, could significantly impact how U.S. multinational companies are taxed on foreign subsidiary earnings. A significant amount of our earnings is generated by our Europe and Asia Pacific subsidiaries. Our future effective tax rates may be adversely affected to the extent earnings are lower than anticipated in countries where we have lower statutory tax rates or we repatriate certain foreign earnings on which U.S. taxes have not previously been provided. 

At January 31, 2015, we had net deferred tax assets of $185.1 million. We believe that we will generate sufficient future taxable income in appropriate tax jurisdictions to realize these assets.

For additional information regarding our income tax provision and reconciliation of our effective rate to the federal statutory rate of 35%, see Note 4, “Income Taxes,” in the Notes to Consolidated Financial Statements.

Other Financial Information

In addition to our results determined under U.S. generally accepted accounting principles (“GAAP”) discussed above, we believe the following non-GAAP measures are useful to investors in evaluating our operating performance. For the fiscal years ended January 31, 2015, 2014, and 2013, our gross profit, gross margin, income from operations, operating margin, net income, and diluted earnings per share on a GAAP and non-GAAP basis were as follows (in millions except for gross margin, operating margin and per share data):

_______________

(1) Effective in the second quarter of fiscal 2013, Autodesk began excluding gains and losses on strategic investments for purposes of its non-GAAP financial measures. Prior period non-GAAP interest and other income (expense), net, net income, and earnings per share amounts have been revised to conform to the current period presentation.

(2) Earnings per share were computed independently for each of the periods presented; therefore the sum of the earnings per share amount for the quarters may not equal the total for the year.

For our internal budgeting and resource allocation process and as a means to evaluate period-to-period comparisons, we use non-GAAP measures to supplement our consolidated financial statements presented on a GAAP basis. These non-GAAP measures do not include certain items that may have a material impact upon our reported financial results. We use non-GAAP measures in making operating decisions because we believe those measures provide meaningful supplemental information regarding our earning

2015 Form 10-K 50

potential and performance for management by excluding certain expenses and charges that may not be indicative of our core business operating results. For the reasons set forth below, we believe these non-GAAP financial measures are useful to investors both because (1) they allow for greater transparency with respect to key metrics used by management in its financial and operational decision-making and (2) they are used by our institutional investors and the analyst community to help them analyze the health of our business. This allows investors and others to better understand and evaluate our operating results and future prospects in the same manner as management, compare financial results across accounting periods and to those of peer companies and to better understand the long-term performance of our core business. We also use some of these measures for purposes of determining company-wide incentive compensation.

There are limitations in using non-GAAP financial measures because non-GAAP financial measures are not prepared in accordance with GAAP and may be different from non-GAAP financial measures used by other companies. The non-GAAP financial measures included above are limited in value because they exclude certain items that may have a material impact upon our reported financial results. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which charges are excluded from the non-GAAP financial measures. We compensate for these limitations by analyzing current and future results on a GAAP basis as well as a non-GAAP basis and also by providing GAAP measures in our public disclosures. The presentation of non-GAAP financial information is meant to be considered in addition to, not as a substitute for or in isolation from, the directly comparable financial measures prepared in accordance with GAAP. We urge investors to review the reconciliation of our non-GAAP financial measures to the comparable GAAP financial measures included below, and not to rely on any single financial measure to evaluate our business.

_______________

(1) Effective in the second quarter of fiscal 2013, Autodesk began excluding gains and losses on strategic investments for purposes of its non-GAAP financial measures. Prior period non-GAAP interest and other income (expense), net, net income, and earnings per share amounts have been revised to conform to the current period presentation.

(2) Earnings per share were computed independently for each of the periods presented; therefore the sum of the earnings per share amount for the quarters may not equal the total for the year.

Our non-GAAP financial measures may exclude the following:

Stock-based compensation expenses.  We exclude stock-based compensation expenses from non-GAAP measures primarily because they are non-cash expenses and management finds it useful to exclude certain non-cash charges to assess the appropriate level of various operating expenses to assist in budgeting, planning, and forecasting future periods. Moreover, because of varying available valuation methodologies, subjective assumptions and the variety of award types that companies can use under FASB ASC Topic 718, we believe excluding stock-based compensation expenses allows investors to make meaningful comparisons between our recurring core business operating results and those of other companies.

Amortization of acquisition-related developed technologies and purchased intangibles.  We incur amortization of acquisition-related developed technology and purchased intangibles in connection with acquisitions of certain businesses and technologies. Amortization of developed technologies and purchased intangibles is inconsistent in amount and frequency and is significantly affected by the timing and size of our acquisitions. Management finds it useful to exclude these variable charges from our cost of revenues to assist in budgeting, planning, and forecasting future periods. Investors should note that the use of intangible assets contributed to our revenues earned during the periods presented and will contribute to our future period revenues as well. Amortization of developed technologies and purchased intangible assets will recur in future periods.

Goodwill impairment.  This is a non-cash charge to write-down goodwill to fair value when there was an indication that the asset was impaired. As explained above, management finds it useful to exclude certain non-cash charges to assess the appropriate level of various operating expenses to assist in budgeting, planning, and forecasting future periods.

Restructuring charges (benefits), net.  These expenses are associated with realigning our business strategies based on current economic conditions. In connection with these restructuring actions, we recognize costs related to termination benefits for former employees whose positions were eliminated, and the closure of facilities and cancellation of certain contracts. We exclude these charges because these expenses are not reflective of ongoing business and operating results. We believe it is useful for investors to understand the effects of these items on our total operating expenses.

Loss (gain) on strategic investments. We exclude gains and losses related to our strategic investments from our non-GAAP measures primarily because management finds it useful to exclude these variable gains and losses on these investments in assessing our financial results. Included in these amounts are non-cash unrealized gains and losses on the derivative components and realized gains and losses on the sale or losses on the impairment of these investments. We believe excluding these items is useful to investors because these excluded items do not correlate to the underlying performance of our business and these losses or gains were incurred in connection with strategic investments which do not occur regularly.

Establishment of a valuation allowance on certain net deferred tax assets.  This is a non-cash charge to record a valuation allowance on certain deferred tax assets. As explained above, management finds it useful to exclude certain non-cash charges to assess the appropriate level of various cash expenses to assist in budgeting, planning, and forecasting future periods.

Discrete tax items. We exclude the GAAP tax provision, including discrete items, from the non-GAAP measure of income, and include a non-GAAP tax provision based upon the projected annual non-GAAP effective tax rate. Discrete tax items include income tax expenses or benefits that do not relate to ordinary income from continuing operations in the current fiscal year, unusual or infrequently occurring items, or the tax impact of certain stock-based compensation. Examples of discrete tax items include, but are not limited to, certain changes in judgment and changes in estimates of tax matters related to prior fiscal years, certain costs related to business combinations, certain changes in the realizability of deferred tax assets or changes in tax law. Management believes this approach assists investors in understanding the tax provision and the effective tax rate related to ongoing operations. We believe the exclusion of these discrete tax items provides investors with useful supplemental information about the Company's operational performance.

2015 Form 10-K 53

Income tax effects on the difference between GAAP and non-GAAP costs and expenses. The income tax effects that are excluded from the non-GAAP measures relate to the tax impact on the difference between GAAP and non-GAAP expenses, primarily due to stock-based compensation, amortization of purchased intangibles and restructuring charges (benefits) for GAAP and non-GAAP measures.

Liquidity and Capital Resources

Our primary source of cash is from the sale of licenses to our products. Our primary use of cash is payment of our operating costs, which consist primarily of employee-related expenses, such as compensation and benefits, as well as general operating expenses for marketing, facilities, and overhead costs. In addition to operating expenses, we also use cash to fund our stock repurchase program and invest in our growth initiatives, which include acquisitions of products, technology, and businesses. See further discussion of these items below.

At January 31, 2015, our principal sources of liquidity were cash, cash equivalents, and marketable securities totaling $2,299.4 million and net accounts receivable of $458.9 million.

In fiscal 2013, we issued $400.0 million aggregate principal amount of 1.95% senior notes due December 15, 2017 and $350.0 million aggregate principal amount of 3.6% senior notes due December 15, 2022, (collectively, the "Senior Notes"). As of March 18, 2015, we have $750.0 million aggregate principal amount of Senior Notes outstanding. Our senior notes do not contain any financial covenants. In addition, we have a line of credit facility that permits unsecured short-term borrowings of up to $400.0 million. The credit facility contains certain customary affirmative and negative covenants and two financial covenants: a leverage ratio, and an interest coverage ratio. The credit facility limits our ability to incur additional indebtedness and has certain other restrictions on our activities as defined in the credit agreement. As of January 31, 2015, we were in compliance with the credit facility’s covenants. We have no amounts outstanding under the credit facility as of March 18, 2015. The credit facility expires in May 2018. Borrowings under the credit facility and the net proceeds from the offering of the Senior Notes are available for general corporate purposes.

Our cash and cash equivalents are held by diversified financial institutions globally. Our primary commercial banking relationship is with Citigroup and its global affiliates. In addition, Citibank N.A., an affiliate of Citigroup, is one of the lead lenders and agent in the syndicate of our $400.0 million line of credit.

The decrease in our cash, cash equivalents, and marketable securities to $2,299.4 million at January 31, 2015 from $2,544.4 million at January 31, 2014 is primarily due to cash used for acquisitions, including business combination and technology purchases, the repurchase of common stock, and lower proceeds from the issuance of common stock as compared to the prior fiscal year. The cash proceeds from the issuance of common stock varies based on our stock price, stock option exercise activity, and the volume of employee purchases under the Employee Stock Purchase Plan (“ESP Plan”). These decreases to cash, cash equivalents, and marketable securities are partially offset by an increase in cash generated by operating activities.

The primary source for net cash provided by operating activities of $708.1 million for fiscal 2015 was net income of $81.8 million increased by the effect of non-cash expenses totaling $311.5 million associated with depreciation, amortization, accretion, and stock-based compensation. In addition, net cash flow provided by changes in operating assets and liabilities was $296.0 million. The primary working capital sources of cash were an increase in deferred revenue and accrued compensation for fiscal 2015 compared to fiscal 2014. Our days sales outstanding in trade receivables was 63 at January 31, 2015 compared to 66 at January 31, 2014. The decrease in days sales outstanding primarily relates to improved billings linearity. The primary working capital uses of cash were a decrease in income taxes payable and an increase in accounts receivable for fiscal 2015 compared to fiscal 2014.

At January 31, 2015, our short-term investment portfolio had an estimated fair value of $615.8 million and a cost basis of $612.3 million. The portfolio fair value consisted of $258.4 million invested in commercial paper, $148.0 million invested in corporate debt securities, $101.9 million invested in certificates of deposit, $37.9 million invested in U.S. government agency securities, and $29.3 million invested in municipal securities.

At January 31, 2015, $40.3 million of trading securities were invested in a defined set of mutual funds as directed by the participants in our Deferred Compensation Plan (see Note 6, “Deferred Compensation,” in the Notes to Consolidated Financial Statements for further discussion).

Long-term cash requirements for items other than normal operating expenses are anticipated for the following: common stock repurchases; the acquisition of businesses, software products, or technologies complementary to our business; and capital expenditures, including the purchase and implementation of internal-use software applications.

Our strategy includes improving our product functionality and expanding our product offerings through internal development as well as through the acquisition of products, technology, and businesses. Acquisitions often increase the speed at which we can deliver product functionality to our customers; however, they entail cost and integration challenges and, in certain instances, negatively impact our operating margins. We continually review these trade-offs in making decisions regarding acquisitions. We currently anticipate that we will continue to acquire products, technology, and businesses as compelling opportunities become available. Our decision to acquire businesses or technology is dependent on our business needs, the availability of suitable sellers and technology, and our own financial condition.

Our cash, cash equivalents, and marketable securities balances are concentrated in a few locations around the world, with substantial amounts held outside of the U.S. As of January 31, 2015, approximately 81% of our total cash, cash equivalents, and marketable securities are located offshore and will fluctuate subject to business needs. Certain amounts held outside the U.S. could be repatriated to the U.S. (subject to local law restrictions), but under current U.S. tax law, could be subject to U.S. income taxes less applicable foreign tax credits. We have provided for the U.S. income tax liability on foreign earnings, except for foreign earnings that are considered permanently reinvested outside the U.S. Our intent is that amounts related to foreign earnings permanently reinvested outside the U.S. will remain outside the U.S. and we will meet our U.S. liquidity needs through ongoing cash flows, external borrowings, or both. We regularly review our capital structure and consider a variety of potential financing alternatives and planning strategies to ensure we have the proper liquidity available in the locations in which it is needed and to fund our existing stock buyback program with cash that has not been permanently reinvested outside the U.S.

Cash from operations could also be affected by various risks and uncertainties, including, but not limited to the risks detailed in Part I, Item 1A titled “Risk Factors.” However, based on our current business plan and revenue prospects, we believe that our existing balances, our anticipated cash flows from operations and our available credit facility will be sufficient to meet our working capital and operating resource expenditure requirements for at least the next 12 months.

Our revenue, earnings, cash flows, receivables, and payables are subject to fluctuations due to changes in foreign currency exchange rates, for which we have put in place foreign currency contracts as part of our risk management strategy. See Part II, Item 7A, “Quantitative and Qualitative Disclosures about Market Risk” for further discussion.

Contractual Obligations

The following table summarizes our significant financial contractual obligations at January 31, 2015 and the effect such obligations are expected to have on our liquidity and cash flows in future periods.

(2) This table generally excludes amounts already recorded on the balance sheet as current liabilities, certain purchase obligations as discussed below, long term deferred revenue, and amounts related to income tax liabilities for uncertain tax positions, since we cannot predict with reasonable reliability the timing of cash settlements to the respective taxing authorities (see Note 4, “Income Taxes” to the Notes to Consolidated Financial Statements).

2015 Form 10-K 55

Notes consist of the Senior Notes issued in December 2012. The Senior Notes consist of $400.0 million aggregate principal amount of 1.95% senior notes due December 15, 2017 notes and $350.0 million aggregate principal amount of 3.6% senior notes due December 15, 2022.

Operating lease obligations consist primarily of obligations for facilities, net of sublease income, computer equipment and other equipment leases.

Purchase obligations are contractual obligations for purchase of goods or services and are defined as agreements that are enforceable and legally binding on Autodesk and that specify all significant terms, including: fixed or minimum quantities to be purchased; fixed, minimum, or variable price provisions; and the approximate timing of the transaction. Purchase obligations relate primarily to enterprise subscription agreements, IT infrastructure costs, and marketing costs.

Deferred compensation obligations relate to amounts held in a rabbi trust under our non-qualified deferred compensation plan. See Note 6, “Deferred Compensation,” in our Notes to Consolidated Financial Statements for further information regarding this plan.

Pension obligations relate to our obligations for pension plans outside of the U.S. See Note 14, “Retirement Benefit Plans,” in our Notes to Consolidated Financial Statements for further information regarding these obligations.

Purchase orders or contracts for the purchase of supplies and other goods and services are not included in the table above. We are not able to determine the aggregate amount of such purchase orders that represent contractual obligations, as purchase orders may represent authorizations to purchase rather than binding agreements. Our purchase orders are based on our current procurement or development needs and are fulfilled by our vendors within short time horizons. We do not have significant agreements for the purchase of supplies or other goods specifying minimum quantities or set prices that exceed our expected requirements for three months. In addition, we have certain software royalty commitments associated with the shipment and licensing of certain products.

The expected timing of payment of the obligations discussed above is estimated based on current information. Timing of payments and actual amounts paid may be different depending on the time of receipt of goods or services or changes to agreed-upon amounts for some obligations.

We provide indemnifications of varying scopes and certain guarantees, including limited product warranties. Historically, costs related to these warranties and indemnifications have not been significant, but because potential future costs are highly variable, we are unable to estimate the maximum potential impact of these guarantees on our future results of operations.

Issuer Purchases of Equity Securities

Autodesk's stock repurchase program is largely to help offset the dilution from the issuance of stock under our employee stock plans and for such other purposes as may be in the interests of Autodesk and its stockholders, and has the effect of returning excess cash generated from our business to stockholders. The number of shares acquired and the timing of the purchases are based on several factors, including general market conditions, the volume of employee stock option exercises, stock issuance, the trading price of our common stock, cash on hand and available in the U.S., and company defined trading windows. During the three and twelve months ended January 31, 2015, we repurchased 1.1 million and 6.9 million shares of our common stock, respectively. At January 31, 2015, 14.8 million shares remained available for repurchase under our current repurchase program approved by the Board of Directors. This program does not have a fixed expiration date. See Note 9, “Stockholders' Equity,” in the Notes to Consolidated Financial Statements for further discussion.

Off-Balance Sheet Arrangements

As of January 31, 2015, we did not have any significant off-balance sheet arrangements other than operating leases, as defined in Item 303(a)(4)(ii) of Regulation S-K.

2015 Form 10-K 56

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Foreign currency exchange risk

Our revenue, earnings, cash flows, receivables, and payables are subject to fluctuations due to changes in foreign currency exchange rates. Our risk management strategy utilizes foreign currency contracts to manage our exposure to foreign currency volatility that exists as part of our ongoing business operations. We utilize cash flow hedge contracts to reduce the exchange rate impact on a portion of the net revenue or operating expense of certain anticipated transactions. In addition, we use balance sheet hedge contracts to reduce the exchange rate risk associated primarily with foreign currency denominated receivables and payables. As of January 31, 2015 and 2014, we had open cash flow and balance sheet hedge contracts with future settlements within one to twelve months. Contracts were primarily denominated in euros, Japanese yen, Swiss francs, British pounds, Canadian dollars, and Australian dollars. We do not enter into any foreign exchange derivative instruments for trading or speculative purposes. The notional amount of our option and forward contracts was $381.2 million and $557.2 million at January 31, 2015 and 2014, respectively.

We use foreign currency contracts to reduce the exchange rate impact on the net revenue and operating expenses of certain anticipated transactions. A sensitivity analysis performed on our hedging portfolio as of January 31, 2015 indicated that a hypothetical 10% appreciation of the U.S. dollar from its value at January 31, 2015 and 2014 would increase the fair value of our foreign currency contracts by $35.1 million and $7.9 million, respectively. A hypothetical 10% depreciation of the dollar from its value at January 31, 2015 would decrease the fair value of our foreign currency contracts by $16.5 million. A hypothetical 10% depreciation of the dollar from its value at January 31, 2014 would increase the fair value of our foreign currency contracts by $3.7 million.

Interest rate risk

Interest rate movements affect both the interest income we earn on our short term investments and the market value of certain longer term securities. At January 31, 2015, we had $1,588.7 million of cash equivalents and marketable securities, including $615.8 million classified as short-term marketable securities and $273.0 million classified as long-term marketable securities. If interest rates were to move up by 50 or 100 basis points over a twelve month period, the potential decline in fair value on our marketable securities would be $2.9 million or $4.7 million, respectively.

Other Market Risk

From time to time we make direct investments in privately held companies. The privately held companies in which we invest are considered inherently risky. The technologies and products these companies have under development are typically in the early stages and may never materialize, which could result in a loss of all or a substantial part of our initial investment in these companies. The evaluation of privately held companies is based on information that we request from these companies, which is not subject to the same disclosure regulations as U.S. publicly traded companies, and as such, the basis for these evaluations is subject to the timing and accuracy of the data received from these companies.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

January 31, 2015

(Tables in millions of dollars, except per share data, unless otherwise indicated)

1.     Business and Summary of Significant Accounting Policies

Business

Autodesk, Inc. (“Autodesk” or the “Company”) is a world leading design software and services company, offering customers productive business solutions through powerful technology products and services. The Company serves customers in the architecture, engineering, and construction; manufacturing; and digital media, consumer, and entertainment industries. The Company’s sophisticated software products enable its customers to experience their ideas before they are real by allowing them to imagine, design, and create their ideas and to visualize, simulate, and analyze real-world performance early in the design process by creating digital prototypes. These capabilities allow Autodesk’s customers to foster innovation, optimize and improve their designs, help save time and money, improve quality, and collaborate with others. Autodesk software products are sold globally, both directly to customers and through a network of resellers and distributors.

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of Autodesk and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.

Reclassifications

During the first quarter of fiscal 2014, Autodesk combined maintenance revenue and cloud services offering-related revenue into one category named “Subscription.” As a result, revenue and cost of revenue related to cloud service offerings previously reflected in “License and other revenue” and “Cost of license and other revenue” were reclassified to “Subscription revenue” and “Cost of subscription revenue.” These revenues and expenses have been reclassified in the Consolidated Statements of Operations for fiscal year 2013 to conform to the current period presentation as follows:

	Fiscal year ended January 31,
	2013
Reclassifications within revenue:
Decrease to License and other revenue	$	(26.5	)
Increase to Subscription revenue	26.5
Reclassifications within cost of revenue:
Decrease to Cost of license and other revenue	$	(32.1	)
Increase to Cost of subscription revenue	32.1

During the second quarter of fiscal 2015, Autodesk elected to present amortization of purchased customer relationships, trade names, patents, and user lists as a separate line item within operating expenses. As a result, amortization previously reflected in “General and Administrative” expense was reclassified to “Amortization of Purchased Intangibles" within Operating Expenses. These expenses have been reclassified in the Consolidated Statements of Operations for fiscal years 2014 and 2013 to conform to the current period presentation as follows:

	Fiscal year ended January 31,
	2014			2013
Reclassifications within operating expenses:
(Decrease) to general and administrative	$	(36.5	)	$	(42.1	)
Increase to amortization of purchased intangibles	36.5			42.1

2015 Form 10-K 63

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in Autodesk’s consolidated financial statements and notes thereto. These estimates are based on information available as of the date of the consolidated financial statements. On a regular basis, management evaluates these estimates and assumptions. Actual results may differ materially from these estimates.

Examples of significant estimates and assumptions made by management involve the determination of the fair value of acquired assets and liabilities, goodwill, financial instruments, long-lived assets and other intangible assets, the realizability of deferred tax assets, and the fair value of stock awards. The Company also makes assumptions, judgments, and estimates in determining the accruals for uncertain tax positions, variable compensation, partner incentive programs, product returns reserves, allowances for doubtful accounts, asset retirement obligations, and legal contingencies.

Foreign Currency Translation and Transactions

The assets and liabilities of Autodesk’s foreign subsidiaries are translated from their respective functional currencies into U.S. dollars at the rates in effect at the balance sheet date, and revenue and expense amounts are translated at exchange rates that approximate those rates in effect during the period in which the underlying transactions occur. Foreign currency translation adjustments are recorded as other comprehensive income (loss).

Gains and losses realized from foreign currency transactions, those transactions denominated in currencies other than the foreign subsidiary’s functional currency, are included in interest and other income, net. Monetary assets and liabilities are remeasured using foreign currency exchange rates at the end of the period, and non-monetary assets are remeasured based on historical exchange rates.

Derivative Financial Instruments

Under its risk management strategy, Autodesk uses derivative instruments to manage its short-term exposures to fluctuations in foreign currency exchange rates which exist as part of ongoing business operations. Autodesk’s general practice is to hedge a majority of transaction exposures denominated in euros, Japanese yen, Swiss francs, British pounds, Canadian dollars, and Australian dollars. These instruments have maturities between one to 12 months in the future. Autodesk does not enter into any derivative instruments for trading or speculative purposes.

The bank counterparties in all contracts expose Autodesk to credit-related losses in the event of their nonperformance. However, to mitigate that risk, Autodesk only contracts with counterparties who meet the Company’s minimum requirements under its counterparty risk assessment process. Autodesk monitors ratings, credit spreads, and potential downgrades on at least a quarterly basis. Based on Autodesk’s on-going assessment of counterparty risk, the Company will adjust its exposure to various counterparties. Autodesk generally enters into master netting arrangements, which reduce credit risk by permitting net settlement of transactions with the same counterparty. However, Autodesk does not have any master netting arrangements in place with collateral features.

Autodesk accounts for its derivative instruments as either assets or liabilities on the balance sheet and carries them at fair value. Gains and losses resulting from changes in fair value are accounted for depending on the use of the derivative and whether it is designated and qualifies for hedge accounting. Derivatives that do not qualify for hedge accounting are adjusted to fair value through earnings. See Note 2, "Financial Instruments" for information regarding Autodesk's hedging activities.

Cash and Cash Equivalents

Autodesk considers all highly liquid investments with insignificant interest rate risk and remaining maturities of three months or less at the date of purchase to be cash equivalents. Cash equivalents are recorded at cost, which approximates fair value.

Marketable Securities

Marketable securities are stated at fair value. Marketable securities maturing within one year that are not restricted are classified as current assets.

2015 Form 10-K 64

Autodesk determines the appropriate classification of its marketable securities at the time of purchase and re-evaluates such classification as of each balance sheet date. Autodesk carries all “available-for-sale securities” at fair value, with unrealized gains and losses, net of tax, reported in stockholders’ equity until disposition or maturity. Autodesk carries all “trading securities” at fair value, with unrealized gains and losses, recorded in “Interest and other income, net” in the Company’s Consolidated Statements of Operations.

All of Autodesk’s marketable securities are subject to a periodic impairment review. The Company recognizes an impairment charge when a decline in the fair value of its investments below the cost basis is judged to be other-than-temporary. Autodesk considers various factors in determining whether to recognize an impairment charge, including the length of time and extent to which the fair value has been less than Autodesk’s cost basis, the financial condition and near-term prospects of the investee, and Autodesk’s intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery in the market value. Autodesk did not record any other-than temporary impairment charges during fiscal years ended January 31, 2015, 2014, and 2013. For additional information, see “Concentration of Credit Risk” within this Note 1 and Note 2, “Financial Instruments.”

Accounts Receivable, Net

Accounts receivable, net, consisted of the following as of January 31:

	2015			2014
Trade accounts receivable	$	495.4		$	464.6
Less: Allowance for doubtful accounts	(6.3		)	(4.9		)
Product returns reserve	(2.6		)	(4.0		)
Partner programs and other obligations	(27.6		)	(32.0		)
Accounts receivable, net	$	458.9		$	423.7

Allowances for uncollectible trade receivables are based upon historical loss patterns, the number of days that billings are past due, and an evaluation of the potential risk of loss associated with problem accounts.

The product returns reserves are based on historical experience of actual product returns, estimated channel inventory levels, the timing of new product introductions, channel sell-in for applicable markets, and other factors.

As part of the indirect channel model, Autodesk has a partner incentive program that uses quarterly attainment of monetary rewards to motivate distributors and resellers to achieve mutually agreed upon business goals in a specified time period. A portion of these incentives reduce license and other revenue in the current period. The remainder, which relates to incentives on our Subscription Program, is recorded as a reduction to deferred revenue in the period the maintenance transaction is billed and subsequently recognized as a reduction to maintenance revenue over the contract period. These incentive balances do not require significant assumptions or judgments. The reserves associated with the partner incentive program are treated on the consolidated balance sheet as either contra account receivable (when due to distributors and direct resellers) or accounts payable (when due to indirect resellers).

Concentration of Credit Risk

Autodesk places its cash, cash equivalents, and marketable securities in highly liquid instruments with, and in the custody of, diversified financial institutions globally with high credit ratings and limits the amounts invested with any one institution, type of security, and issuer.

Geographical concentrations of consolidated cash, cash equivalents, and marketable securities held by Autodesk as of January 31:

	2015		2014
United States	19	%	25	%
Other Americas	1	%	1	%
Europe, Middle East, and Africa (“EMEA”)	56	%	57	%
Asia Pacific (“APAC”)	24	%	17	%

2015 Form 10-K 65

Autodesk’s primary commercial banking relationship is with Citigroup Inc. and its global affiliates. Citibank, N.A., an affiliate of Citigroup, is one of the lead lenders and an agent in the syndicate of Autodesk’s $400.0 million line of credit facility. It is Autodesk’s policy to limit the amounts invested with any one institution by type of security and issuer.

Autodesk’s accounts receivable are derived from sales to a large number of resellers, distributors, and direct customers in the Americas; EMEA; and APAC geographies. Autodesk performs ongoing evaluations of these partners' financial condition and limits the amount of credit extended when deemed necessary, but generally does not require collateral from such parties. Total sales to the Company's largest distributor Tech Data Corporation, and its global affiliates (“Tech Data”), accounted for 25%, 24%, and 23% of Autodesk's net revenue for fiscal years ended January 31, 2015, 2014, and 2013, respectively. The majority of the net revenue from sales to Tech Data relates to Autodesk's Platform Solutions and Emerging Business ("PSEB") segment and is for sales made outside of the United States. In addition, Tech Data accounted for 22% and 24% of trade accounts receivable at January 31, 2015 and 2014, respectively.

Computer Equipment, Software, Furniture, and Leasehold Improvements, Net

Computer equipment, software, and furniture are depreciated using the straight-line method over the estimated useful lives of the assets, which range from three to five years. Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated useful lives or the lease term. Depreciation expense was $52.1 million in fiscal 2015, $47.2 million in fiscal 2014, and $45.6 million in fiscal 2013.

Computer equipment, software, furniture, leasehold improvements and the related accumulated depreciation at January 31 were as follows:

	2015			2014
Computer hardware, at cost	$	194.0		$	163.0
Computer software, at cost	84.9			80.9
Leasehold improvements, land, and buildings, at cost	176.3			163.7
Furniture and equipment, at cost	53.0			51.7
Computer software, hardware, leasehold improvements, furniture, and equipment, at cost	508.2			459.3
Less: Accumulated depreciation	(349.0		)	(329.0		)
Computer software, hardware, leasehold improvements, furniture, and equipment, net	$	159.2		$	130.3

Costs incurred for computer software developed or obtained for internal use are capitalized for application development activities, if material, and immediately expensed for preliminary project activities and post-implementation activities. These capitalized costs are amortized over the software’s expected useful life, which is generally three years. During fiscal 2015, Autodesk wrote-off $25.8 million of fully depreciated assets.

Software Development Costs

Software development costs incurred prior to the establishment of technological feasibility are included in research and development expenses. Autodesk defines establishment of technological feasibility as the completion of a working model. Software development costs incurred subsequent to the establishment of technological feasibility through the period of general market availability of the products are capitalized and generally amortized over a three year period, if material. Autodesk had no material capitalized software development costs at January 31, 2015 and January 31, 2014.

Other Intangible Assets, Net

Other intangible assets include developed technologies, customer relationships, trade names, patents, user lists, and the related accumulated amortization. These assets are shown as “Developed technologies, net” and as part of “Other assets” in the Consolidated Balance Sheet. The majority of Autodesk’s other intangible assets are amortized to expense over the estimated economic life of the product, which ranges from one to ten years. Amortization expense for developed technologies, customer relationships, trade names, patents, and user lists was $92.9 million in fiscal 2015, $80.7 million in fiscal 2014 and $82.0 million in fiscal 2013.

2015 Form 10-K 66

Other intangible assets and related accumulated amortization at January 31 were as follows:

	2015			2014
Developed technologies, at cost	$	538.4		$	462.4
Customer relationships, trade names, patents, and user lists, at cost (1)	348.9			268.1

(1) Included as a net balance in “Other assets” in the Consolidated Balance Sheet. Customer relationships and trade names include the effects of foreign currency translation.

The weighted average amortization period for developed technologies, customer relationships, and trade names during fiscal 2015 was 4.2 years. Expected future amortization expense for developed technologies, customer relationships, trade names, patents, and user lists for each of the fiscal years ended thereafter is as follows:

	Fiscal Year ended January 31,
2016	$	73.2
2017	49.7

Thereafter	4.2
Total	$	171.9

Goodwill

Goodwill consists of the excess of the consideration transferred over the fair value of net assets acquired in business combinations. Autodesk assigns goodwill to the reporting unit associated with each business combination, and tests goodwill for impairment annually in its fourth fiscal quarter or more often if circumstances indicate a potential impairment. For purposes of the goodwill impairment test, a reporting unit is an operating segment or one level below.

Autodesk has the option to perform an assessment of qualitative factors of impairment (“optional assessment”) prior to necessitating a two-step quantitative impairment test. Should the optional assessment be utilized for any given fiscal year, qualitative factors to consider include cost factors; financial performance; legal, regulatory, contractual, political, business, or other factors; entity specific factors; industry and market considerations, macroeconomic conditions, and other relevant events and factors affecting the reporting unit. If, after assessing the totality of events or circumstances, it is more likely than not that the fair value of the reporting unit is greater than its carrying value, then performing the two-step impairment test is unnecessary.

Therefore, the two-step quantitative impairment test is necessary when either Autodesk does not utilize the optional assessment or, as a result of the optional assessment, it is not more likely than not that the fair value of the reporting unit is greater than its carrying value. In performing the two-step impairment test, Autodesk uses discounted cash flow models which include assumptions regarding projected cash flows. Variances in these assumptions could have a significant impact on Autodesk's conclusion as to whether goodwill is impaired, or the amount of any impairment charge. Impairment charges, if any, result from instances where the fair values of net assets associated with goodwill are less than their carrying values. As changes in business conditions and assumptions occur, Autodesk may be required to record impairment charges. The process of evaluating the potential impairment of goodwill is subjective and requires significant judgment at many points during the analysis. The value of Autodesk’s goodwill could also be impacted by future adverse changes such as: (i) declines in Autodesk’s actual financial results, (ii) a sustained decline in Autodesk’s market capitalization, (iii) significant slowdown in the worldwide economy or the industries Autodesk serves, or (iv) changes in Autodesk’s business strategy or internal financial forecast results.

For the fiscal 2015 annual goodwill impairment testing, Autodesk had five reporting units: PSEB, Manufacturing ("MFG"), Architecture, Engineering, and Construction ("AEC"), Media and Entertainment ("M&E"), and Delcam.

2015 Form 10-K 67

For the annual impairment assessment in fiscal 2015, Autodesk utilized the optional assessment for Delcam. Based on a review of the qualitative factors described above, we determined that for our Delcam reporting unit, it was more likely than not that the fair value of the reporting unit exceeded the carrying value. As a result, we concluded that performing the two-step impairment test was not necessary for Delcam.

For each of the remaining four reporting units, Autodesk did not utilize the optional assessment but rather performed the quantitative two-step impairment test. In performing the quantitative two-step test, Autodesk used a discounted cash flow model which included assumptions regarding projected cash flows. Based on this testing, Autodesk determined that the fair value was substantially in excess of the carrying value for each of the four reporting units and therefore the goodwill of each reporting unit was not impaired during the fiscal year ended January 31, 2015. In addition, Autodesk did not recognize any goodwill impairment losses in fiscal 2014 or 2013.

The change in the carrying amount of goodwill during the fiscal year ended January 31, 2015 is as follows:

Impairment of Long-Lived Assets

At least annually or more frequently as circumstances dictate, Autodesk reviews its long-lived assets for impairment whenever impairment indicators exist.  Autodesk continually monitors events and changes in circumstances that could indicate the carrying amounts of its long-lived assets may not be recoverable. When such events or changes in circumstances occur, Autodesk assesses recoverability of these assets.  Recoverability is measured by comparison of the carrying amounts of the assets to the future undiscounted cash flows the assets are expected to generate.  If the long-lived assets are considered to be impaired, the impairment to be recognized is equal to the amount by which the carrying value of the assets exceeds its fair market value. Autodesk did not recognize any impairment of long-lived assets during the fiscal years ended January 31, 2015, 2014, and 2013, respectively.

In addition to the recoverability assessments, Autodesk routinely reviews the remaining estimated useful lives of its long-lived assets. Any reduction in the useful life assumption will result in increased depreciation and amortization expense in the quarter when such determinations are made, as well as in subsequent quarters.

Deferred Tax Assets

Deferred tax assets arise primarily from tax credits, net operating losses, and timing differences for reserves, accrued liabilities, stock options, deferred revenue, purchased technologies, and capitalized intangibles, partially offset by the establishment of U.S. deferred tax liabilities on unremitted earnings from certain foreign subsidiaries, and valuation allowances against U.S. and foreign deferred tax assets. We perform a quarterly assessment of the recoverability of these net deferred tax assets and believe that we will generate sufficient future taxable income in appropriate tax jurisdictions to realize the net deferred tax assets. They are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to reverse. Valuation allowances are established when necessary to reduce gross deferred tax assets to the amount “more likely than not” expected to be realized.

Revenue Recognition

Autodesk recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed or determinable, and collection is probable.

2015 Form 10-K 69

For multiple element arrangements containing only software and software-related elements, Autodesk allocates the sales price among each of the deliverables using the residual method, under which revenue is allocated to undelivered elements based on their vendor-specific objective evidence (“VSOE”) of fair value. VSOE is the price charged when an element is sold separately or a price set by management with the relevant authority. If Autodesk does not have VSOE of an undelivered element, revenue recognition is deferred on the entire sales arrangement until all elements for which Autodesk does not have VSOE are delivered. If Autodesk does not have VSOE for undelivered maintenance or services, the revenue for the arrangement is recognized over the longest contractual service period in the arrangement. Revenue recognition for significant lines of business is discussed further below.

For multiple element arrangements involving non-software elements, including cloud subscription services, our revenue recognition policy is based upon the accounting guidance contained in ASC 605, Revenue Recognition. For these arrangements, Autodesk first allocates the total arrangement consideration based on the relative selling prices of the software group of elements as a whole and the non-software elements. Autodesk then further allocates consideration within the software group to the respective elements within that group using the residual method as described above. Autodesk exercises judgment and uses estimates in connection with the determination of the amount of revenue to be recognized in each accounting period.

Autodesk allocates the total arrangement consideration among the various elements based on a selling price hierarchy. The selling price for a deliverable is based on its VSOE if available, third-party evidence ("TPE") if VSOE is not available, or the best estimated selling price ("BESP") if neither VSOE nor TPE is available. BESP represents the price at which Autodesk would transact for the deliverable if it were sold regularly on a standalone basis. To establish BESP for those elements for which neither VSOE nor TPE are available, Autodesk performs a quantitative analysis of pricing data points for historical standalone transactions involving such elements for a twelve-month period. As part of this analysis, Autodesk monitors and evaluates the BESP against actual pricing to ensure that it continues to represent a reasonable estimate of the standalone selling price, considering several other external and internal factors including, but not limited to, pricing and discounting practices, contractually stated prices, the geographies in which Autodesk offers products and services, and the type of customer (i.e. distributor, value-added reseller, and direct end user, among others). Autodesk analyzes BESP at least annually or on a more frequent basis if a significant change in our business necessitates a more timely analysis, or if significant selling price variances are experienced.

Autodesk’s assessment of likelihood of collection is also a critical element in determining the timing of revenue recognition. If collection is not probable, the revenue will be deferred until the earlier of when collection is deemed probable or cash is received.

License and other revenue are comprised of two components: (1) all forms of product license revenue and (2) other revenue.

(1) All Forms of Product License Revenue

Product license revenue includes: software license revenue from the sale of new seat licenses and upgrades and product revenue for Creative Finishing.

(2) Other Revenue

Other revenue includes revenue from consulting, training, Autodesk Developers Network, and Creative Finishing customer support, and is recognized over time, as the services are performed.

Autodesk's Subscription revenue consists of two components: maintenance revenue for our software products and revenue for our cloud service offerings, including Autodesk 360. Autodesk's maintenance program provides our commercial and educational customers of perpetual products with a cost effective and predictable budgetary option to obtain the productivity benefits of our new releases and enhancements when and if released during the term of their contracts. Under Autodesk's maintenance program, customers are eligible to receive unspecified upgrades when and if available, downloadable training courses, and online support. Autodesk recognizes maintenance revenue ratably over the term of the maintenance agreement, which is generally between one and three years but can occasionally be as long as five years. Revenue for Autodesk's cloud service offerings is recognized ratably over the contract term commencing with the date Autodesk's service is made available to customers and all other revenue recognition criteria have been satisfied.

Taxes Collected from Customers

Autodesk nets taxes collected from customers against those remitted to government authorities in the consolidated financial statements. Accordingly, taxes collected from customers are not reported as revenue.

Shipping and Handling Costs

Shipping and handling costs are included in cost of revenue for all periods presented.

Stock-based Compensation Expense

The following table summarizes stock-based compensation expense for fiscal 2015, 2014, and 2013, respectively, as follows:

	Fiscal Year Ended January 31,
	2015			2014			2013
Cost of license and other revenue	$	4.6		$	3.8		$	3.7
Cost of subscription	4.3			2.2			1.5
Marketing and sales	72.4			58.6			64.3
Research and development	56.0			43.7			61.8
General and administrative	28.3			23.9			25.0
Stock-based compensation expense related to stock awards and ESP Plan purchases	165.6			132.2			156.3
Tax benefit	(45.2		)	(36.4		)	(35.5		)
Stock-based compensation expense related to stock awards and ESP Plan purchases, net	$	120.4		$	95.8		$	120.8

Autodesk determines the grant-date fair value of its share-based payment awards using a Black-Scholes Merton Option ("BSM") pricing model or the quoted stock price on the date of grant, unless the awards are subject to market conditions, in which case Autodesk uses a binomial-lattice model (e.g., Monte Carlo simulation model). The Monte Carlo simulation model utilizes multiple input variables to estimate the probability that market conditions will be achieved. Autodesk uses the following assumptions to estimate the fair value of stock-based awards:

	Fiscal Year Ended		Fiscal Year Ended		Fiscal Year Ended
	January 31, 2015		January 31, 2014		January 31, 2013
	Performance Stock Unit (1)	ESP Plan	Performance Stock Unit (1)	ESP Plan	Stock Option (2)	ESP Plan
Range of expected volatilities	30%	29 - 33%	34%	27 - 36%	41 - 45%	41 - 44%
Range of expected lives (in years)	N/A	0.5 - 2.0	N/A	0.5 - 2.0	3.6 - 4.6	0.5 - 2.0
Expected dividends	—%	—%	—%	—%	—%	—%
Range of risk-free interest rates	0.1%	0.0 - 0.6%	0.1%	0.1 - 0.4%	0.5 - 0.8%	0.1 - 0.3%

 _______________

(1) Autodesk did not grant PSUs in fiscal 2013 that were subject to market conditions.

(2) Autodesk did not grant stock options in fiscal 2015 or 2014.

Autodesk estimates expected volatility for stock-based awards based on the average of the following two measures. The first is a measure of historical volatility in the trading market for the Company’s common stock, and the second is the implied volatility of traded forward call options to purchase shares of the Company’s common stock. The expected volatility for PSUs subject to market conditions includes the expected volatility of Autodesk's peer companies within the S&P Computer Software Select Index.

Autodesk estimates the expected life of stock-based awards using both exercise behavior and post-vesting termination behavior as well as consideration of outstanding options.

Autodesk did not pay cash dividends in fiscal 2015, 2014, or 2013 and does not anticipate paying any cash dividends in the foreseeable future. Consequently, an expected dividend yield of zero is used in the Black-Scholes-Merton option pricing model and the Monte Carlo simulation model.

2015 Form 10-K 71

The risk-free interest rate used in the BSM option pricing model and the Monte Carlo simulation model for stock-based awards is the historical yield on U.S. Treasury securities with equivalent remaining lives.

Autodesk recognizes expense only for the stock-based awards that are ultimately expected to vest. Therefore, Autodesk has developed an estimate of the number of awards expected to cancel prior to vesting (“forfeiture rate”). The forfeiture rate is estimated based on historical pre-vest cancellation experience and is applied to all stock-based awards. The Company estimates forfeitures at the time of grant and revises those estimates in subsequent periods if actual forfeitures differ from those estimates.

Advertising Expenses

Advertising costs are expensed as incurred. Total advertising expenses incurred were $23.9 million in fiscal 2015, $15.6 million in fiscal 2014, and $15.6 million in fiscal 2013.

Net Income Per Share

Basic net income per share is computed based on the weighted average number of shares of common stock outstanding for the period, excluding stock options and restricted stock units. Diluted net income per share is computed based upon the weighted average shares of common shares outstanding for the period and potentially dilutive common shares, including the effect of stock options and restricted stock units under the treasury stock method.

Defined Benefit Pension Plans

The funded status of Autodesk's defined benefit pension plans is recognized in the Consolidated Balance Sheets. The funded status is measured as the difference between the fair value of plan assets and the projected benefit obligation for the fiscal years presented. The projected benefit obligation represents the actuarial present value of benefits expected to be paid upon retirement based on employee services already rendered and estimated future compensation levels. The fair value of plan assets represents the current market value of Autodesk's cumulative company and participant contributions made to the various plans in effect.

Net periodic benefit cost is recorded in the Consolidated Statements of Operations and includes service cost, interest cost, expected return on plan assets, amortization of prior service costs, and gains or losses previously recognized as a component of other comprehensive income. Certain events, such as changes in the employee base, plan amendments, and changes in actuarial assumptions may result in a change in the defined benefit obligation and the corresponding change to other comprehensive income.

Gains and losses and prior service costs not recognized as a component of net periodic benefit cost in the Consolidated Statements of Operations as they arise are recognized as a component of other comprehensive income in the Consolidated Statements of Comprehensive Income. Those gains and losses and prior service costs are subsequently amortized as a component of net periodic benefit cost over the average remaining service lives of the plan participants using a corridor approach to determine the portion of gain or loss subject to amortization.

The measurement of projected benefit obligations and net periodic benefit cost is based on estimates and assumptions that reflect the terms of the plans and use participant-specific information such as compensation, age and years of services, as well as certain assumptions, including estimates of discount rates, expected return of plan assets, rate of compensation increases, interest rates, and mortality rates.

Accounting Standards in Fiscal 2015

With the exception of those discussed below, there have been no recent changes in accounting pronouncements issued by the FASB or adopted by the Company during the fiscal year ended January 31, 2015, that are of significance, or potential significance, to the Company.

2015 Form 10-K 72

Accounting Standards Adopted

Effective February 1, 2014, Autodesk prospectively adopted FASB's Accounting Standards Update (“ASU”) 2013-11 regarding ASC Topic 740 “Income Tax.” This ASU clarifies the guidance on the presentation of an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the consolidated financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. The adoption of this ASU resulted in an $81.9M reduction of both our long term taxes payable and long-term deferred tax assets as of January 31, 2015.

Recently Issued Accounting Standards

On May 28, 2014, the FASB issued ASU 2014-09 regarding ASC Topic 606 “Revenue from Contracts with Customers.” This ASU provides principles for recognizing revenue for the transfer of promised goods or services to customers with the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU will be effective for Autodesk’s fiscal year beginning February 1, 2017. Early adoption is not permitted. Autodesk is currently evaluating the accounting, transition, and disclosure requirements of the standard and cannot currently estimate the financial statement impact of adoption.

(4) Included in “Prepaid expenses and other current assets,” "Other assets," or “Other accrued liabilities” in the accompanying Consolidated Balance Sheets.

Autodesk classifies its marketable securities as either short-term or long-term based on each instrument’s underlying contractual maturity date. Marketable securities with remaining maturities of less than 12 months are classified as short-term and marketable securities with remaining maturities greater than 12 months are classified as long-term. Autodesk may sell certain of its marketable securities prior to their stated maturities for strategic purposes or in anticipation of credit deterioration.

Autodesk applies fair value accounting for certain financial assets and liabilities, which consist of cash equivalents, marketable securities, and other financial instruments, on a recurring basis. The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: (Level 1) observable inputs such as quoted prices in active markets; (Level 2) inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and (Level 3) unobservable inputs for which there is little or no market data, which require Autodesk to develop its own assumptions. When determining fair value, Autodesk uses observable market data and relies on unobservable inputs only when observable market data is not available. There have been no transfers between fair value measurement levels during the year ended January 31, 2015.

2015 Form 10-K 75

Autodesk's cash equivalents, marketable securities, and financial instruments are primarily classified within Level 1 or Level 2 of the fair value hierarchy. Autodesk values it's available for sale securities on pricing from pricing vendors, who may use quoted prices in active markets for identical assets (Level 1) or inputs other than quoted prices that are observable either directly or indirectly in determining fair value (Level 2). Autodesk's Level 2 securities are valued primarily using observable inputs other than quoted prices in active markets for identical assets and liabilities. Autodesk's Level 3 securities consist of investments held in auction rate securities, convertible debt securities, and derivative contracts which are valued using probability weighted discounted cash flow models and some of the inputs to the models are unobservable in the market.

A reconciliation of the change in Autodesk’s Level 3 items for the fiscal years ended January 31, 2015 and 2014 was as follows:

	Fair Value Measurements Using Significant Unobservable Inputs
	(Level 3)
		Derivative Contracts			Convertible Debt Securities			Taxable Auction-Rate Securities			Total
Balance at January 31, 2013		$	10.7		$	17.5		$	4.2		$	32.4

The following table summarizes the estimated fair value of Autodesk's “available-for-sale securities” classified by the contractual maturity date of the security:

	January 31, 2015
	Cost		Fair Value
Due in 1 year	$	575.4	$	575.5
Due in 1 year through 5 years	276.9		278.1
Total	$	852.3	$	853.6

As of January 31, 2015 and 2014, Autodesk did not have any securities in a continuous unrealized loss position for greater than twelve months.

As of January 31, 2015 and 2014 Autodesk had $52.6 million and $49.8 million, respectively, in direct investments of privately held companies accounted for under the cost method, which are periodically assessed for other-than-temporary impairment. If Autodesk determines that an other-than-temporary impairment has occurred, Autodesk writes down the investment to its fair value. Autodesk estimates fair value of its cost method investments considering available information such as pricing in recent rounds of financing, current cash positions, earnings and cash flow forecasts, recent operational performance, and any other readily available market data. During fiscal 2015, Autodesk recorded $19.2 million in other-than-temporary impairments on its privately held equity investments. During fiscal 2014, Autodesk recorded no other-than-temporary impairment on its privately held equity investments. The impairment expense was recorded in “Interest and other (expense) income, net” on the Company's Consolidated Statement of Operations.

2015 Form 10-K 76

The sales or settlement of “available-for-sale securities” in fiscal 2015 and fiscal 2014 resulted in a gain of $0.7 million and a loss of $0.2 million, respectively. The sales or redemptions of “available-for-sale securities” in fiscal 2013 resulted in no gains or losses. The losses and gains were recorded in "Interest and other (expense) income, net" on the Company's Consolidated Statement of Operations.

Proceeds from the sale and maturity of marketable securities for fiscal 2015 and fiscal 2014 were $1,159.0 million and $1,279.1 million, respectively.

Derivative Financial Instruments

Under its risk management strategy, Autodesk uses derivative instruments to manage its short-term exposures to fluctuations in foreign currency exchange rates that exist as part of ongoing business operations. Autodesk's general practice is to hedge a portion of transaction exposures denominated in euros, Japanese yen, Swiss francs, British pounds, Canadian dollars and Australian dollars. These instruments have maturities between one to twelve months in the future. Autodesk does not enter into derivative instrument transactions for trading or speculative purposes.

The bank counterparties to the derivative contracts potentially expose Autodesk to credit-related losses in the event of their nonperformance. However, to mitigate that risk, Autodesk only contracts with counterparties who meet the Company's minimum requirements under its counterparty risk assessment process. Autodesk monitors ratings, credit spreads, and potential downgrades on at least a quarterly basis. Based on Autodesk's on-going assessment of counterparty risk, the Company will adjust its exposure to various counterparties. Autodesk generally enters into master netting arrangements, which reduce credit risk by permitting net settlement of transactions with the same counterparty.  However, Autodesk does not have any master netting arrangements in place with collateral features.

Foreign currency contracts designated as cash flow hedges

Autodesk uses foreign currency contracts to reduce the exchange rate impact on a portion of the net revenue or operating expense of certain anticipated transactions. These contracts are designated and documented as cash flow hedges. The effectiveness of the cash flow hedge contracts is assessed quarterly using regression analysis as well as other timing and probability criteria. To receive cash flow hedge accounting treatment, all hedging relationships are formally documented at the inception of the hedge and the hedges are expected to be highly effective in offsetting changes to future cash flows on hedged transactions. The gross gains and losses on these hedges are included in “Accumulated other comprehensive loss” and are reclassified into earnings at the time the forecasted revenue or expense is recognized. In the event the underlying forecasted transaction does not occur, or it becomes probable that it will not occur, Autodesk reclassifies the gain or loss on the related cash flow hedge from “Accumulated other comprehensive loss” to “Interest and other (expense) income, net” in the Company's Consolidated Financial Statements at that time.

The net notional amount of these contracts are presented net settled and were $336.6 million at January 31, 2015 and $351.7 million at January 31, 2014. Outstanding contracts are recognized as either assets or liabilities on the Consolidated Balance Sheet at fair value. The majority of the net gain of $42.8 million remaining in “Accumulated other comprehensive loss” as of January 31, 2015 is expected to be recognized into earnings within the next twelve months.

Derivatives not designated as hedging instruments

Autodesk uses foreign currency contracts which are not designated as hedging instruments to reduce the exchange rate risk associated primarily with foreign currency denominated receivables and payables. These forward contracts are marked-to-market at the end of each fiscal quarter with gains and losses recognized as “Interest and other (expense) income, net.” These derivative instruments do not subject the Company to material balance sheet risk due to exchange rate movements because gains and losses on these derivative instruments are intended to offset the gains or losses resulting from the settlement of the underlying foreign currency denominated receivables and payables. The net notional amounts of these foreign currency contracts are presented net settled and were $44.6 million at January 31, 2015 and $205.5 million at January 31, 2014.

From time to time and consistent with its risk management policy, Autodesk also uses derivative instruments to hedge its economic exposure related to committed, in-process acquisitions priced in foreign currency.  Such derivatives do not qualify for hedge accounting and are marked-to-market through earnings, with any gain or loss reflected immediately in “Interest and other (expense) income, net,” in each period. 

2015 Form 10-K 77

In addition to these foreign currency contracts, Autodesk holds derivative instruments issued by privately held companies, which are not designated as hedging instruments. These derivatives consist of certain conversion options on the convertible debt securities held by Autodesk and an option to acquire a privately held company. These derivatives are recorded at fair value as of each balance sheet date and are recorded in “Other assets.” Changes in the fair values of these instruments are recognized in income as “Interest and other (expense) income, net.”

Fair Value of Derivative Instruments:

The fair value of derivative instruments in Autodesk’s Consolidated Balance Sheets were as follows as of January 31, 2015 and January 31, 2014:

	Balance Sheet Location	Fair Value at
		January 31, 2015		January 31, 2014
Derivative Assets
Foreign currency contracts designated as cash flow hedges	Prepaid expenses and other current assets (1)	$	20.4	$	4.4

3.     Employee and Director Stock Plans

Stock Plans

As of January 31, 2015, Autodesk maintained two active stock plans for the purpose of granting equity awards to employees and to non-employee members of Autodesk’s Board of Directors: the 2012 Employee Stock Plan (as amended, the “2012 Employee Plan”), which is available only to employees, and the Autodesk 2012 Outside Directors’ Stock Plan (“2012 Directors' Plan”), which is available only to non-employee directors. Additionally, there are three expired or terminated plans with options outstanding. The exercise price of all stock options granted under these plans was equal to the fair market value of the stock on the grant date.

The 2012 Employee Plan was approved by Autodesk's stockholders and became effective on January 6, 2012. On January 14, 2014, Autodesk's stockholders approved amendments to the 2012 Employee Plan, which increased the number of shares reserved for issuance under the plan by 11.4 million shares and added additional performance goals to the plan. The 2012 Employee Plan replaced the 2008 Employee Stock Plan, as amended ("2008 Plan"), and no further equity awards may be granted under the 2008 Plan. The 2012 Employee Plan reserves up to 32.6 million shares which includes 26.6 million shares reserved under the 2012 Employee Plan, as well as up to 6.0 million shares forfeited under certain prior employee stock plans during the life of the 2012 Employee Plan. The 2012 Employee Plan permits the grant of stock options, restricted stock units, and restricted stock awards. Each restricted stock unit or restricted stock award granted will be counted against the shares authorized for issuance under the 2012 Employee Plan as 1.79 shares. If a granted option, restricted stock unit, or restricted stock award expires or becomes unexercisable for any reason, the unpurchased or forfeited shares that were granted may be returned to the 2012 Employee Plan and may become available for future grant under the 2012 Employee Plan. As of January 31, 2015, 22.1 million shares subject to options or restricted stock awards have been granted under the 2012 Employee Plan. Options and restricted stock that were granted under the 2012 plan vest over periods ranging from immediately upon grant to over a three year period and options expire 10 years from the date of grant. The 2012 Employee Plan will expire on June 30, 2022. At January 31, 2015, 12.3 million shares were available for future issuance under the 2012 Employee Plan.

The 2012 Director's Plan was approved by Autodesk's stockholders and became effective on January 6, 2012. The 2012 Directors' Plan replaced the 2010 Outside Directors' Stock Plan, as amended ("2010 Plan"). The 2012 Directors' Plan permits the grant of stock options, restricted stock units, and restricted stock awards to non-employee members of Autodesk’s Board of Directors. Each restricted stock unit or restricted stock award granted will be counted against the shares authorized for issuance under the 2012 Directors' Plan as 2.11 shares. As of January 31, 2015, 0.6 million shares subject to restricted stock unit awards have been granted under the 2012 Directors' Plan. Restricted stock units that were granted under the 2012 Outside Directors' Plan vest over one to three years from the date of grant. The 2012 Directors' Plan reserved 2.6 million shares of Autodesk common stock. The 2012 Directors' Plan will expire on June 30, 2022. At January 31, 2015, 2.0 million shares were available for future issuance under the 2012 Director's Plan.

Restricted Stock:

A summary of restricted stock unit activity for the fiscal year ended January 31, 2015 is as follows:

	Unreleased Restricted Stock Units		Weighted average grant date fair value
	(in thousands)
Unreleased restricted stock units at January 31, 2014	6,515.6		$	39.15
Granted	4,481.8		54.17

Performance Adjustment (1)	(74.7	)	42.23
Unreleased restricted stock units at January 31, 2015	7,801.3		$	48.46

_______________

(1) Based on Autodesk's financial results for the performance period, the fiscal 2014 and 2013 performance stock units were earned at 65.8% and 92.3% of the target award, respectively. The vesting of the performance stock units is subject to the holders satisfying the remaining service condition of the awards.

For the restricted stock units granted during fiscal years ended January 31, 2015, 2014, and 2013, the weighted average grant date fair value was $54.17, $42.37, and $33.32, respectively. The grant date fair value of the shares vested during fiscal years ended January 31, 2015, 2014, and 2013 was $100.0 million, $73.8 million, and $33.6 million, respectively.

During the fiscal year ended January 31, 2015, Autodesk granted 4.0 million restricted stock units. The restricted stock units vest over periods ranging from immediately upon grant to a pre-determined date that is typically within three years from the date of grant. Restricted stock units are not considered outstanding stock at the time of grant, as the holders of these units are not entitled to any of the rights of a stockholder, including voting rights. The fair value of the restricted stock units is expensed ratably over the vesting period. Autodesk recorded stock-based compensation expense related to restricted stock units of $118.9 million, $74.9 million, and $70.5 million during fiscal years ended January 31, 2015, 2014, and 2013, respectively. Included in the $70.5 million incurred in fiscal 2013, Autodesk incurred $16.6 million relating to the acceleration of vesting of equity awards held in Socialcam for Socialcam employees immediately prior to the acquisition. As of January 31, 2015, total compensation cost not yet recognized of $245.0 million related to non-vested awards, is expected to be recognized over a weighted average period of 1.8 years. At January 31, 2015, the number of restricted stock units granted but unvested was 6.9 million.

2015 Form 10-K 81

During the fiscal year ended January 31, 2015, Autodesk granted 0.5 million performance stock units ("PSUs") for which the ultimate number of shares earned is determined based on the achievement of performance criteria at the end of the stated performance period. The performance criteria are based upon billings and subscriptions goals adopted by the Compensation and Human Resource Committee (the “Annual Financial Results”), as well as total stockholder return compared against the S&P Computer Software Select Index (“Relative TSR”). Each PSU covers a three year period:

• Up to one third of the PSU may vest following year one depending upon the achievement of Annual Financial Results for year one as well as 1 year Relative TSR (covering year one).

• Up to one third of the PSU may vest following year two depending upon the achievement of Annual Financial Results for year two as well as 2 year Relative TSR (covering years one and two).

• Up to one third of the PSU may vest following year three depending upon the achievement of Annual Financial Results for year three as well as 3 year Relative TSR (covering years one, two, and three).

PSUs are not considered outstanding stock at the time of grant, as the holders of these units are not entitled to any of the rights of a stockholder, including voting rights. Autodesk has determined the grant-date fair value for these awards using a Monte Carlo simulation model since the awards are subject to a market condition. The fair value of the performance restricted stock units is expensed using the accelerated attribution method over the vesting period. Autodesk recorded stock-based compensation expense related to PSUs of $17.5 million, $8.7 million, and $8.1 million during fiscal year ended January 31, 2015, 2014, and 2013 respectively. As of January 31, 2015, total compensation cost not yet recognized of $2.5 million related to non-vested PSUs, is expected to be recognized over a weighted average period of 0.8 years. At January 31, 2015, the number of PSUs granted but unvested was 0.9 million.

1998 Employee Qualified Stock Purchase Plan (“ESP Plan”)

Under Autodesk’s ESP Plan, which was approved by stockholders in 1998, eligible employees may purchase shares of Autodesk’s common stock at their discretion using up to 15% of their eligible compensation subject to certain limitations, at not less than 85% of fair market value as defined in the ESP Plan. At January 31, 2015, a total of 40.7 million shares were available for future issuance. This amount automatically increases on the first trading day of each fiscal year by an amount equal to the lesser of 10.0 million shares or 2% of the total of (1) outstanding shares plus (2) any shares repurchased by Autodesk during the prior fiscal year. Under the ESP Plan, the Company issues shares on the first trading day following March 31 and September 30 of each fiscal year. The ESP Plan expires during fiscal 2018.

Autodesk issued 2.1 million shares under the ESP Plan at an average price of $33.91 per share in fiscal 2015, 2.9 million shares at an average price of $22.61 per share in fiscal 2014, and 2.9 million shares at an average price of $21.79 per share in fiscal 2013. The weighted average grant date fair value of awards granted under the ESP Plan during fiscal 2015, 2014, and 2013, calculated as of the award grant date using the BSM option pricing model, was $15.14, $11.80, and $12.21 per share, respectively. Autodesk recorded $23.9 million, $22.9 million, and $34.0 million of compensation expense associated with the ESP Plan in fiscal 2015, 2014, and 2013, respectively.

During fiscal year 2015, the Company reduced its current federal and state taxes payable by $0.5 million related to excess tax benefits from non-qualified stock options, offsetting additional paid-in capital. Pursuant to accounting standards related to stock-based compensation, the Company has unrecorded excess stock option tax benefits of $217.9 million as of January 31, 2015. These amounts will be credited to additional paid-in-capital when such amounts reduce cash taxes payable. Foreign pretax income was $302.5 million in fiscal 2015, $380.5 million in fiscal 2014, and $383.3 million in fiscal 2013.

The differences between the U.S. statutory rate and the aggregate income tax provision are as follows:

Effective February 1, 2014, Autodesk prospectively adopted FASB's Accounting Standards Update (“ASU”) 2013-11

regarding ASC Topic 740 “Income Tax.”  This ASU clarifies the guidance on the presentation of an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the consolidated financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. Research and development tax credit carryforwards and foreign tax credit carryforwards as of January 31, 2015 have been reduced by unrecognized tax benefits to the extent the tax credit carryforwards would be expected to offset tax liabilities in the event the uncertain tax positions are disallowed.

The valuation allowance increased by $3.6 million, $15.9 million, and $3.8 million in fiscal 2015, 2014, and 2013, respectively. The fiscal 2015, 2014, and 2013 changes in valuation allowance were primarily related to U.S. and Canadian deferred taxes.

Autodesk provides U.S. income taxes on the earnings of foreign subsidiaries, except to the extent subsidiaries' earnings are considered permanently reinvested outside the U.S. As of January 31, 2015, the cumulative amount of earnings upon which U.S. income taxes have not been provided was $1,809.4 million. The unrecognized deferred tax liability for these earnings was approximately $514.4 million.

Realization of the net deferred tax assets of $185.1 million is dependent upon the company's ability to generate future taxable income in appropriate tax jurisdictions to obtain benefit from the reversal of temporary differences, net operating loss carryforwards and tax credits. The amount of deferred tax assets considered realizable is subject to adjustment in future periods if estimates of future taxable income are reduced and Autodesk then determines that it is not more likely than not to realize such deferred tax assets.

As of January 31, 2015, Autodesk had $21.7 million of cumulative federal tax loss carryforwards and $354.3 million of cumulative state tax loss carryforwards, which may be available to reduce future income tax liabilities in certain jurisdictions. These federal and state tax loss carryforwards will expire beginning fiscal 2015 through fiscal 2034 and fiscal 2015 through fiscal 2034, respectively. Autodesk also had $7.4 million of cumulative UK tax loss carryforwards, which may be available to reduce future income tax liabilities indefinitely. Autodesk had $9.2 million of cumulative federal and state capital loss carryforwards as of January 31, 2015 which are available to offset future capital gains through fiscal 2018.

As of January 31, 2015, Autodesk had $104.7 million of cumulative federal research tax credit carryforwards, $54.8 million of cumulative California state research tax credit carryforwards, and $59.8 million of cumulative Canadian federal tax credit carryforwards, which may be available to reduce future income tax liabilities in the respective jurisdictions. The federal credit carryforwards will expire beginning fiscal 2020 through fiscal 2035, the state credit carryforwards may reduce future

2015 Form 10-K 84

California income tax liabilities indefinitely, and the Canadian tax credit carryforwards will expire beginning fiscal 2024 through fiscal 2034. Autodesk also has $163.6 million of cumulative foreign tax credit carryforwards, which may be available to reduce future U. S. tax liabilities. The foreign tax credit will expire beginning fiscal 2019 through fiscal 2026.

Utilization of net operating losses and tax credits may be subject to an annual limitation due to ownership change limitations provided in the Internal Revenue Code and similar state provisions. This annual limitation may result in the expiration of net operating losses and credits before utilization.

As a result of certain business and employment actions and capital investments undertaken by Autodesk, income earned in certain Europe and Asia Pacific countries is subject to reduced tax rates through fiscal 2016 and 2020, respectively with extensions available with incremental business and employment actions. The net income tax benefits attributable to the tax status of these business arrangements are estimated to be $1.2 million ($0.01 basic net income per share) in fiscal 2015, $9.7 million ($0.04 basic net income per share) in fiscal 2014, and $6.6 million ($0.03 basic net income per share) in fiscal 2013. The income tax benefits were offset partially by accruals of U.S. income taxes on undistributed earnings, among other factors.

As of January 31, 2015, the company had $245.8 million of gross unrecognized tax benefits, of which $227.3 million would impact the effective tax rate, if recognized. It is possible that the amount of unrecognized tax benefits will change in the next twelve months; however an estimate of the range of the possible change cannot be made at this time.

A reconciliation of the beginning and ending amount of the gross unrecognized tax benefits is as follows:

	Fiscal Year Ended January 31,
	2015			2014			2013
Gross unrecognized tax benefits at the beginning of the fiscal year	$	222.1		$	212.7		$	201.1
Increases for tax positions of prior years	3.2			1.8			0.4
Decreases for tax positions of prior years	(2.5		)	(0.3		)	(0.4		)
Increases for tax positions related to the current year	33.2			15.3			17.8
Decreases relating to settlements with taxing authorities	(5.4		)	(4.6		)	(3.0		)
Reductions as a result of lapse of the statute of limitations	(4.8		)	(2.8		)	(3.2		)
Gross unrecognized tax benefits at the end of the fiscal year	$	245.8		$	222.1		$	212.7

It is the company's continuing practice to recognize interest and/or penalties related to income tax matters in income tax expense. Autodesk had $2.0 million, $2.8 million, and $1.9 million, net of tax benefit, accrued for interest and an immaterial amount accrued for penalties related to unrecognized tax benefits as of January 31, 2015, 2014, and 2013, respectively.

Autodesk and its subsidiaries are subject to income tax in the United States as well as numerous state and foreign jurisdictions. Autodesk's U.S. and state income tax returns for fiscal year 2003 through fiscal year 2015 remain open to examination. In addition, Autodesk files tax returns in multiple foreign taxing jurisdictions with open tax years ranging from fiscal year 2003 to 2015.

5.     Acquisitions

During the fiscal years ended January 31, 2015 and January 31, 2014, Autodesk completed the business combinations and technology purchases described below. The results of operations for the following acquisitions are included in the accompanying Consolidated Statement of Operations since their respective acquisition dates. Pro forma results of operations have not been presented because the effects of the following acquisitions, individually and in the aggregate, were not material to Autodesk's Consolidated Financial Statements.

For acquisitions accounted for as business combinations, Autodesk recorded the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The fair values assigned to the identifiable intangible assets acquired were based on estimates and assumptions determined by management. Autodesk recorded the excess of consideration transferred over the aggregate fair values as goodwill.

2015 Form 10-K 85

Fiscal 2015 Acquisitions

On June 27, 2014, Autodesk acquired Shotgun Software, Inc. (“Shotgun”) for total consideration of $54.5 million, of which $51.2 million was cash consideration. Prior to acquiring Shotgun, Autodesk had a convertible debt investment in the company with an acquisition-date fair value of $3.3 million using a market approach to value the investment. Shotgun was a privately-owned company that provided a cloud-based production management solution that enabled digital studios to track, schedule, review, and collaborate on projects and images. Shotgun has been integrated into, and the related goodwill was assigned to, Autodesk's M&E segment. Goodwill is not expected to be deductible for U.S. income tax purposes.

On May 29, 2014, Autodesk acquired all the outstanding shares of Within Technologies Limited ("Within Technologies”) for total cash consideration of $88.0 million. Autodesk used its non-U.S.-based cash for the transaction. Within Technologies is a United Kingdom based developer of design and simulation software for next generation manufacturing processes.  The Within Technologies acquisition is expected to accelerate Autodesk’s development of tools and technologies for advanced manufacturing.  Within Technologies has been integrated into Autodesk’s PSEB reportable segment. The amount of goodwill that is expected to be deductible for U.S. income tax purposes is $78.9 million.

On February 6, 2014, Autodesk acquired the entire issued and to be issued share capital of Delcam plc (“Delcam”), for $284.6 million. Delcam was previously listed as a public company (LON: DLC) and is a leading supplier of advanced CADCAM and industrial measurement solutions for the manufacturing industry. With this transaction Autodesk gains Delcam’s range of design, manufacturing, and inspection software that provide automated CADCAM solutions for a variety of industries, ranging from aerospace to toys and sports equipment. The transaction was structured as a cash offer for all the outstanding shares of Delcam, and Delcam has been integrated into Autodesk's MFG reportable segment. The amount of goodwill that is expected to be deductible for U.S. income tax purposes is $166.0 million.

During the fiscal year ended January 31, 2015, Autodesk also completed 21 other business combination and technology acquisitions for total cash consideration of $234.5 million. These business combinations and technology acquisitions were not material individually or in aggregate to Autodesk's Consolidated Financial Statements.

The following table summarizes the fair value of the assets acquired and liabilities assumed by major class for each of the business combinations and technology acquisitions completed during the fiscal year ended January 31, 2015:

	Shotgun			Within			Delcam			Other

Net tangible assets (liabilities)	0.1			(0.3		)	32.7			1.3
	$	54.5		$	88.0		$	284.6		$	234.5

For Shotgun and certain other business combinations, the allocation of purchase price consideration to certain assets and liabilities is not yet finalized. Autodesk's estimates and assumptions are subject to change within the measurement period (up to one year from the acquisition date). The primary areas of the preliminary purchase price allocation that are not yet finalized are amounts for tax assets and liabilities, pending finalization of estimates and assumptions in respect of certain tax aspects of the transaction and residual goodwill.

Fiscal 2014 Acquisitions

On November 21, 2013, Autodesk acquired all of the outstanding shares of Graitec SA (“Graitec”) for total cash consideration of $87.0 million.  The acquisition enhances Autodesk’s current offerings for structural engineering and expands our portfolio of technology for Building Information Modeling ("BIM") for structural fabrication and detailing. Graitec has been integrated into Autodesk’s AEC segment. The amount of goodwill that is deductible for U.S. income tax purposes is $64.1 million.

6.     Deferred Compensation

At January 31, 2015, Autodesk had marketable securities totaling $888.8 million, of which $40.3 million related to investments in debt and equity securities that are held in a rabbi trust under non-qualified deferred compensation plans. The total related deferred compensation liability was $40.3 million at January 31, 2015, of which $5.3 million was classified as current and $35.0 million was classified as non-current liabilities. The value of debt and equity securities held in the rabbi trust at January 31, 2014 was $38.9 million. The total related deferred compensation liability at January 31, 2014 was $38.9 million, of which $1.9 million was classified as current and $37.0 million was classified as non-current liabilities. The securities are recorded in the Consolidated Balance Sheets under the current portion of "Marketable Securities". The current and non-current portions of the liability are recorded in the Consolidated Balance Sheets under “Accrued compensation” and “Other liabilities,” respectively.

7.     Borrowing Arrangements

In December 2012, Autodesk issued $400.0 million aggregate principal amount of 1.95% senior notes due December 15, 2017 and $350.0 million aggregate principal amount of 3.6% senior notes due December 15, 2022, (collectively, the "Senior Notes"). Autodesk received net proceeds of $739.3 million from issuance of the Senior Notes, net of a discount of $4.5 million and issuance costs of $6.1 million. Both the discount and issuance costs are being amortized to interest expense over the respective terms of the Senior Notes using the effective interest method. The proceeds of the Senior Notes are available for general corporate purposes. Autodesk may redeem the Senior Notes at any time, subject to a make whole premium. In addition, upon the occurrence of certain change of control triggering events, Autodesk may be required to repurchase the Senior Notes, at a price equal to 101% of their principal amount, plus accrued and unpaid interest to the date of repurchase. The Senior Notes contain restrictive covenants that limit our ability to create certain liens, to enter into certain sale and leaseback transactions and to consolidate or merge with, or convey, transfer, or lease all or substantially all of our assets, subject to significant qualifications and exceptions. Based on quoted market prices, the fair value of the Senior Notes was approximately $759.9 million as of January 31, 2015.

Autodesk’s line of credit facility permits unsecured short-term borrowings of up to $400.0 million with an option to request an increase in the amount of the credit facility by up to an additional $100.0 million, and is available for working capital or other business needs. This credit agreement contains customary covenants that could restrict the imposition of liens on Autodesk’s assets, and restrict the Company’s ability to incur additional indebtedness or make dispositions of assets if Autodesk fails to maintain the financial covenants. The financial covenants consist of a leverage ratio, and an interest coverage ratio. The line of credit is syndicated with various financial institutions, including Citibank, N.A., an affiliate of Citigroup, which is one of the lead lenders and an agent. As of January 31, 2015, we were in compliance with the credit facility’s covenants.The credit facility expires in May 2018. At January 31, 2015 and January 31, 2014, Autodesk had no outstanding borrowings on this line of credit.

8.     Commitments and Contingencies

Lease commitments

Autodesk leases office space and computer equipment under non-cancellable operating lease agreements that expire at various dates through 2088. The leases generally provide that Autodesk pay taxes, insurance, and maintenance expenses related to the leased assets. Certain of these lease arrangements contain escalation clauses whereby monthly rent increases over time. At January 31, 2015, the aggregate future minimum lease payments required were as follows:

2016	$	55.4
2017	47.3
2018	40.7
2019	29.1
2020	19.5
Thereafter	32.6
	224.6
Less: Sublease income	1.9
	$	222.7

Rent expense related to these operating leases recognized on a straight-line basis over the lease period, was as follows:

	Fiscal Year Ended January 31,
	2015		2014		2013
Rent expense	$	55.0	$	50.2	$	56.1

Purchase commitments

In the normal course of business, Autodesk enters into various purchase commitments for goods or services. Total non-cancellable purchase commitments as of January 31, 2015 were approximately $85.4 millionfor periods through fiscal 2020. These purchase commitments primarily result from contracts for the acquisition of IT infrastructure, marketing, and software development services.

Autodesk has certain royalty commitments associated with the shipment and licensing of certain products. Royalty expense is generally based on a dollar amount per unit shipped or a percentage of the underlying revenue. Royalty expense, which was recorded under cost of license and other revenue on Autodesk’s Consolidated Statements of Operations, was $17.9 million in fiscal 2015, $18.0 million in fiscal 2014, and $16.4 million in fiscal 2013.

Guarantees and Indemnifications

In the normal course of business, Autodesk provides indemnifications of varying scopes, including limited product warranties and indemnification of customers against claims of intellectual property infringement made by third parties arising from the use of its products or services. Autodesk accrues for known indemnification issues if a loss is probable and can be reasonably estimated. Historically, costs related to these indemnifications have not been significant, and because potential future costs are highly variable, Autodesk is unable to estimate the maximum potential impact of these indemnifications on its future results of operations.

In connection with the purchase, sale, or license of assets or businesses with third parties, Autodesk has entered into or assumed customary indemnification agreements related to the assets or businesses purchased, sold or licensed. Historically, costs related to these indemnifications have not been significant, and because potential future costs are highly variable, Autodesk is unable to estimate the maximum potential impact of these indemnifications on its future results of operations.

As permitted under Delaware law, Autodesk has agreements whereby it indemnifies its officers and directors for certain events or occurrences while the officer or director is, or was, serving at Autodesk’s request in such capacity. The maximum potential amount of future payments Autodesk could be required to make under these indemnification agreements is unlimited;

2015 Form 10-K 88

however, Autodesk has directors’ and officers’ liability insurance coverage that is intended to reduce its financial exposure and may enable Autodesk to recover a portion of any future amounts paid. Autodesk believes the estimated fair value of these indemnification agreements in excess of applicable insurance coverage is minimal.

Legal Proceedings

Autodesk is involved in a variety of claims, suits, investigations, and proceedings in the normal course of business activities including claims of alleged infringement of intellectual property rights, commercial, employment, piracy prosecution, business practices, and other matters. In the Company's opinion, resolution of pending matters is not expected to have a material adverse impact on its consolidated results of operations, cash flows, or its financial position. Given the unpredictable nature of legal proceedings, there is a reasonable possibility that an unfavorable resolution of one or more such proceedings could in the future materially affect the Company's results of operations, cash flows, or financial position in a particular period, however, based on the information known by the Company as of the date of this filing and the rules and regulations applicable to the preparation of the Company's financial statements, any such amount is either immaterial or it is not possible to provide an estimated amount of any such potential loss.

9.     Stockholders' Equity

Preferred Stock

Under Autodesk’s Certificate of Incorporation, 2.0 million shares of preferred stock are authorized. At January 31, 2015, there were no preferred shares issued or outstanding. The Board of Directors has the authority to issue the preferred stock in one or more series and to fix rights, preferences, privileges, and restrictions, including dividends and the number of shares constituting any series or the designation of such series, without any further vote or action by the stockholders.

Common Stock Repurchase Programs

Autodesk has a stock repurchase program that is used to offset dilution from the issuance of stock under the Company’s employee stock plans and for such other purposes as may be in the interests of Autodesk and its stockholders, which has the effect of returning excess cash generated from the Company’s business to stockholders. Autodesk repurchased and retired 6.9 million shares in fiscal 2015 at an average repurchase price of $53.83 per share, 10.5 million shares in fiscal 2014 at an average repurchase price of $40.43 per share, and 12.5 million shares in fiscal 2013 at an average repurchase price of $34.50.

At January 31, 2015, 14.8 million shares remained available for repurchase under the repurchase program approved by the Board of Directors. The number of shares acquired and the timing of the purchases are based on several factors, including general market and economic conditions, the number of employee stock option exercises and stock issuances, the trading price of Autodesk common stock, cash on hand and available in the United States, cash requirements for acquisitions, and Company defined trading windows.

10.    Interest and Other (Expense) Income, net

Interest and other (expense) income, net, consists of the following:

(1) For comparability, the presentation of prior period balances were adjusted to align with current year presentation.

Reclassifications related to gains and losses on available for sale securities are included in Interest and other (expense) income, net. Refer to "Note 2: Financial Instruments" for the amount and location of reclassifications related to derivative instruments. Reclassifications of the defined benefit pension components are included in the computation of net periodic benefit cost. Refer to "Note 14: Retirement Benefit Plans."

12.     Net Income Per Share

Basic net income per share is computed using the weighted average number of shares of common stock outstanding for the period, excluding stock options and restricted stock units. Diluted net income per share is based upon the weighted average number of shares of common stock outstanding for the period and potentially dilutive common shares, including the effect of stock options and restricted stock units under the treasury stock method. The following table sets forth the computation of the numerators and denominators used in the basic and diluted net income per share amounts:

	Fiscal Year Ended January 31,
	2015		2014		2013
Numerator:
Net income	$	81.8	$	228.8	$	247.4
Denominator:
Denominator for basic net income per share—weighted average shares	227.1		224.0		226.4
Effect of dilutive securities	5.3		5.6		5.3
Denominator for dilutive net income per share	232.4		229.6		231.7
Basic net income per share	$	0.36	$	1.02	$	1.09
Diluted net income per share	$	0.35	$	1.00	$	1.07

The computation of diluted net income per share does not include shares that are anti-dilutive under the treasury stock method because their exercise prices are higher than the average market value of Autodesk’s stock during the fiscal year. For the fiscal years ended January 31, 2015, 2014, and 2013, 0.1 million, 5.4 million, and 9.6 million potentially anti-dilutive shares, respectively, were excluded from the computation of net income per share.

13.     Segments

Autodesk reports segment information based on the “management” approach. The management approach designates the internal reporting used by management for making decisions and assessing performance as the source of the Company’s reportable segments. Autodesk has four reportable segments: AEC, PSEB, MFG, and M&E. Autodesk has no material inter-segment revenue.

The AEC, PSEB, and MFG segments derive revenue from the sale of licenses for software products and services to customers who design, build, manage, or own building, manufacturing, and infrastructure projects. Autodesk's M&E segment derives revenue from the sale of products to creative professionals, post-production facilities, and broadcasters for a variety of applications, including feature films, television programs, commercials, music and corporate videos, interactive game production, web design, and interactive web streaming.

AEC software products help to improve the way building, civil infrastructure, process plant, and construction projects are designed, built, and managed. A broad portfolio of solutions enables greater efficiency, accuracy, and sustainability across the entire project lifecycle. Autodesk AEC solutions include advanced technology for BIM, AutoCAD-based design and documentation productivity software, sustainable design analysis applications, and collaborative project management solutions. BIM, an integrated process for building and infrastructure design, analysis, documentation, and construction, uses consistent, coordination information to improve communication and collaboration between the extended project team. AEC provides a comprehensive portfolio of BIM solutions that help customers deliver projects faster and more economically, while minimizing environmental impact. AEC’s revenue primarily includes revenue from the sales of licenses of Autodesk Building Design Suites, Autodesk Revit, Autodesk Infrastructure Design Suites, AutoCAD Civil 3D, and AutoCAD Map 3D.

PSEB includes Autodesk’s design product, AutoCAD. Autodesk’s AutoCAD product is a platform product that underpins the Company’s design product offerings for the industries it serves. For example, AEC and MFG offer tailored versions of AutoCAD software for the industries they serve. Autodesk’s AutoCAD product also provides a platform for Autodesk’s developer partners to build custom solutions for a range of diverse design-oriented markets. PSEB's revenue primarily includes revenue from sales of AutoCAD and AutoCAD LT, the AutoCAD Design Suite and many other design products, including consumer design products, as well as from sales of licenses of other Autodesk's design products.

MFG provides the manufacturers in automotive and transportation, industrial machinery, consumer products and building products with comprehensive digital prototyping solutions that bring together design data from all phases of the product development process to develop a single digital model created in Autodesk Inventor software. Autodesk’s solutions for digital prototyping enable a broad group of manufacturers to realize benefits with minimal disruption to existing workflows. MFG’s revenue primarily includes revenue from the sales of licenses of Autodesk Product Design Suites, Autodesk Inventor, AutoCAD Mechanical, and Autodesk Moldflow products.

M&E consists of two product groups: Animation, including design visualization, and Creative Finishing. Animation products, such as Autodesk 3ds Max, Autodesk Maya, and the Autodesk Entertainment Creation Suites, provide tools for digital sculpting, modeling, animation, effects, rendering and compositing, for design visualization, visual effects, and games production. M&E products are also included in a number of PSEB, AEC, and MFG focused suites. Creative Finishing products, such as Autodesk Flame, Autodesk Smoke, and Autodesk Lustre, provide editing, finishing, and visual effects design and color grading.

All of Autodesk’s reportable segments distribute their respective products primarily through authorized resellers and distributors and, to a lesser extent, through direct sales to end-users.

The accounting policies of the reportable segments are the same as those described in Note 1, “Business and Summary of Significant Accounting Policies.” Autodesk evaluates each segment’s performance on the basis of gross profit. Autodesk currently does not separately accumulate and report asset information by segment, except for goodwill, which is disclosed in Note 1, “Business and Summary of Significant Accounting Policies.”

14.     Retirement Benefit Plans

Pretax Savings Plan

Autodesk has a 401(k) plan that covers nearly all U.S. employees. Eligible employees may contribute up to 50% of their pretax salary, subject to limitations mandated by the Internal Revenue Service. Autodesk makes voluntary cash contributions and matches a portion of employee contributions in cash. Autodesk’s contributions were $11.2 million in fiscal 2015, $8.1 million in fiscal 2014, and $7.9 million in fiscal 2013. Autodesk does not allow participants to invest in Autodesk common stock through the 401(k) plan.

Defined Benefit Pension Plans

Autodesk maintains certain defined benefit pension plans to employees primarily located in countries outside of the U.S, particularly the United Kingdom, Switzerland, and Japan. The Company deposits funds for specific plans, consistent with the requirements of local law, with insurance companies, third-party trustees, or into government-managed accounts, and accrues for the unfunded portion of the obligation, where material. Depending on the design of the plan, local customs, and market circumstances, the liabilities of a plan may exceed qualified plan assets.

2015 Form 10-K 94

As of January 31, 2015, the aggregate accumulated benefit obligation was $124.3 million for the pension plans ($45.3 million as of January 31, 2014). Included in the aggregate data in the following tables are the amounts applicable to our defined benefit plans, with accumulated benefit obligations in excess of plan assets, as well as plans with projected benefit obligations in excess of plan assets. Amounts related to such plans at the end of each period were as follows:

	Fiscal Year Ended January 31,
	2015		2014
Plans with accumulated benefit obligations in excess of plan assets:
Accumulated benefit obligations	$	124.0	$	45.3
Plan Assets	103.9		40.7
Plans with projected benefit obligations in excess of plan assets:
Projected benefit obligations	$	144.7	$	62.2
Plan Assets	104.2		40.7

Pension Plan Assets

The investments of the plans are managed by insurance companies or third-party investment managers selected by Autodesk's Trustees, consistent with regulations or market practice of the country where the assets are invested. Investments managed by qualified insurance companies or third-party investment managers under standard contracts follow local regulations, and Autodesk is not actively involved in their investment strategies.

Pension plan assets measured at fair value on a recurring basis consisted of the following investment categories at the end of each period as follows:

	Fiscal Year Ended January 31,
	2015								2014
	Level 1		Level 2		Level 3		Total		Total
Investment fund	$	55.7	$	4.9	$	—	$	60.6	$	—
Insurance contracts	—		43.5		—		43.5		40.2
Total assets measured at fair value	55.7		48.4		—		104.1		40.2
Cash	0.1		—		—		0.1		0.5
Total pension plan assets at fair value	$	55.8	$	48.4	$	—	$	104.2	$	40.7

The assets held in the investment fund in the preceding table are invested in a diversified growth fund actively managed by Russell Investments in association with Aon Hewitt. The objective of the fund is to generate capital appreciation on a long-term basis through a diversified portfolio of investments. The fund aims to deliver equity-like returns in the medium to long term with around two-thirds the volatility of equity markets. The fair value of the assets held in the investment fund classified as Level 1 are priced daily using observable inputs for identical assets. The fair value of the assets held in the investment fund classified as Level 2 are priced monthly at net asset value with quarterly redemption attributes.

The insurance contracts in the preceding table represent the immediate cash surrender value of assets managed by qualified insurance companies. Autodesk does not have control over the target allocation or visibility of the investment strategies of those investments. Insurance contracts and investments held by insurance companies made up 42% of total plan assets as of January 31, 2015 (99% as of January 31, 2014).

	Fiscal Year Ended January 31,
	2015			2014			2013
Net loss (gain) for period	$	18.4		$	(3.9	)	$	6.3
Amortization of prior service credit	0.1			0.1			0.1

2015 Form 10-K 96

The estimated amounts that will be amortized from AOCI into net periodic benefit cost over the next fiscal year for the qualified defined benefit pension plan and other benefit plans are as follows:

	Pension Benefits
Amortization of prior service credit	$	0.1
Amortization of the net loss	(1.5		)
Total amortization	$	(1.4	)

Assumptions

Weighted average actuarial assumptions used to determine costs for the plans for each period were as follows:

	Fiscal Year Ended January 31,
	2015		2014		2013
Discount rate	3.3	%	2.3	%	1.8	%
Expected long-term rate of return on plan assets	3.9	%	1.9	%	2.0	%
Rate of compensation increase	2.2	%	2.2	%	2.1	%

The weighted-average expected long-term rate of return for the plan assets is 3.9%. The weighted-average expected long-term rate of return on plan assets is based on the interest rates guaranteed under the insurance contracts, and the expected rate of return appropriate for each category of assets weighted for the distribution within the diversified investment fund. The assumptions used for the plans are based upon customary rates and practices for the location of the plans. Factors such as asset class allocations, long-term rates of return (actual and expected), and results of periodic asset liability modeling studies are considered when constructing the long-term rate of return assumption for our pension plans.

Weighted average actuarial assumptions used to determine benefit obligations for the plans at the end of each period were as follows:

	Fiscal Year Ended January 31,
	2015		2014		2013
Discount rate	2.4	%	2.2	%	1.8	%
Rate of compensation increase	1.2	%	2.2	%	2.0	%

In selecting the appropriate discount rate for the plans, the Company uses country-specific information, adjusted to reflect the duration of the particular plan.The discount rate was based on highly rated long-term bond indexes and yield curves that match the duration of the plan’s benefit obligations.

Defined Contribution Plans

Autodesk also provides defined contribution plans in certain foreign countries where required by statute. Autodesk’s funding policy for foreign defined contribution plans is consistent with the local requirements in each country. Autodesk’s contributions to these plans were $23.5 million in fiscal 2015, $22.3 million in fiscal 2014, and $21.5 million in fiscal 2013.

Other Plans

In addition, Autodesk offers a non-qualified deferred compensation plan to certain key employees whereby they may defer a portion (or all) of their annual compensation until retirement or a different date specified by the employee in accordance with terms of the plan. See Note 6, “Deferred Compensation,” for further discussion.

15.     Restructuring Reserves

During fiscal 2014, the Board of Directors of the Company approved a world-wide restructuring plan in order to re-balance staffing levels to better align them with the evolving needs of the business. The Company authorized plan included a reduction of approximately 85 positions and the consolidation of four leased facilities, with a total cost of approximately $15.0 million ("Fiscal 2014 Plan"). By July 31, 2014, the personnel and facilities related actions included in this restructuring plan were substantially complete.

During fiscal 2013, the Board of Directors of the Company approved a world-wide restructuring plan in line with the Company's strategy, including its continuing shift to cloud and mobile computing ("Fiscal 2013 Plan"). The approved plan resulted in a reduction of approximately 500 positions and the consolidation of eight leased facilities, with an aggregate charge of $46.2 million to date. By January 31, 2014, the personnel and facilities related actions included in this restructuring plan were substantially complete.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders of Autodesk, Inc.

We have audited the accompanying consolidated balance sheets of Autodesk, Inc. as of January 31, 2015 and 2014, and the related consolidated statements of operations, comprehensive income, stockholders’ equity, and cash flows for each of the three years in the period ended January 31, 2015. Our audits also included the financial statement schedule listed in the Index at Item 15(a)(2). These financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Autodesk, Inc. at January 31, 2015 and 2014, and the consolidated results of its operations and its cash flows for each of the three years in the period ended January 31, 2015, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Autodesk, Inc.’s internal control over financial reporting as of January 31, 2015, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated March 18, 2015 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders of Autodesk, Inc.

We have audited Autodesk, Inc.’s internal control over financial reporting as of January 31, 2015, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). Autodesk, Inc.’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

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

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

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

As indicated in the accompanying Management’s Report on Internal Control Over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of Delcam, plc, which is included in the 2015 consolidated financial statements of Autodesk, Inc. and constituted 6 percent of total assets as of January 31, 2015 and 2 percent of revenues, for the year then ended. Our audit of internal control over financial reporting of Autodesk, Inc. also did not include an evaluation of the internal control over financial reporting of Delcam plc.

In our opinion, Autodesk, Inc. maintained, in all material respects, effective internal control over financial reporting as of January 31, 2015, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Autodesk, Inc. as of January 31, 2015 and 2014, and the related consolidated statements of operations, comprehensive income, stockholders’ equity, and cash flows for each of the three years in the period ended January 31, 2015 of Autodesk, Inc. and our report dated March 18, 2015 expressed an unqualified opinion thereon.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management evaluated, with the participation of our Chief Executive Officer and Chief Financial Officer, the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Annual Report on Form 10-K as required by paragraph (d) of Rule 13a-15 of the Exchange Act. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures (as defined under Rule 13a-15(e) of the Exchange Act) are effective at the reasonable assurance level to ensure that information we are required to disclose in reports that we file or submit under the Securities Exchange Act of 1934, as amended (i) is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms; and (ii) is accumulated and communicated to Autodesk’s management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Our disclosure controls and procedures are designed to provide reasonable assurance that such information is accumulated and communicated to our management.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal controls over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended) during the quarter ended January 31, 2015 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended). Our management assessed the effectiveness of our internal control over financial reporting as of January 31, 2015. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in the 2013 Internal Control—Integrated Framework. Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will necessarily prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are 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, within Autodesk have been detected.

In accordance with guidance issued by the Securities and Exchange Commission, companies are permitted to exclude acquisitions from their final assessment of internal control over financial reporting for the first fiscal year in which the acquisition occurred. Our management’s evaluation of internal control over financial reporting excluded the internal control activities of Delcam plc (Delcam), which we acquired February 6, 2014, as discussed in Note 5, “Acquisitions,” of the Notes to the Consolidated Financial Statements.

INTERNATIONAL EMPLOYEE STOCK PURCHASE PLAN

(as amended and restated effective September 21, 2011)

(Sub-Plan of the Autodesk, Inc. 1998 Employee Qualified Stock Purchase Plan, as amended and restated)

The following constitute the provisions of the International Employee Stock Purchase Plan, as amended and restated (herein called the “Sub-Plan”) of Autodesk, Inc. (herein called the “Company”), a sub-plan of the Autodesk, Inc. 1998 Employee Qualified Stock Purchase Plan, as amended and restated (herein called the “US Plan”).

1.Purpose. The Sub-Plan is intended to provide eligible Employees of the Company’s Affiliates the opportunity to acquire a proprietary interest in the Company through the purchase of shares of the Company’s common stock at periodic intervals with their accumulated payroll deductions or other approved contributions. The Sub-Plan is not intended to qualify as an employee stock purchase plan under Section 423 (b) of the U.S. Internal Revenue Code of 1986, as amended.

All provisions of this Sub-Plan shall be governed by the U.S. Plan, except as otherwise provided herein.

The Sub-Plan became effective on the designated Effective Date.

2.Definitions.

All definitions in the Sub-Plan shall be interpreted in accordance with the U.S. Plan except as otherwise provided herein.

(a)“Affiliate” shall mean a corporation, partnership, joint venture or other business entity, or branch of such business entity, domestic or foreign, of which not less than 50% of the voting shares are held by the Company or a Subsidiary, whether or not such corporation now exists or is hereafter organized or acquired by the Company or an Affiliate.

(b)“Effective Date” shall mean December 6, 2007; provided, however, that any Affiliate which extends the benefits of this Sub-Plan to its Employees after December 6, 2007, shall designate a subsequent Effective Date with respect to its employee-Participants.

(c)“Employee” shall mean any person employed by an Affiliate.

(d)“Participant” means any Employee who meets the eligibility and participation requirements set forth in Sections 3 and 4, below.

3.Eligibility. Each individual who is (a) an Employee as of the last day of the Enrollment Period for the applicable Offering Period, and (b) employed by an Affiliate (or legal extension of an Affiliate, such as a branch office) operating in one of the countries listed on the attached Schedule A (which Schedule A may be amended form time to time by the Board or a committee thereof), shall be eligible to participate in the Sub-Plan for that Offering Period.

4.Participation.

(a)An eligible Employee may become a Participant in the Plan by completing a subscription agreement authorizing payroll deductions or other approved contributions on the

1

form provided by the Company and filing it with the Company’s payroll office during the Enrollment Period for the applicable Offering Period, unless a later or earlier time for filing the subscription agreement is set by the Board for all eligible Employees with respect to a given offering.

(b)Payroll deductions for a Participant shall continue at the rate specified in the subscription agreement throughout the Offering Period with automatic re-enrollment for the Offering Period which commences the day after the Exercise Date at the same rate specified in the original subscription agreement, subject to any change in subscription rate made pursuant to Section 6(c) of the U.S. Plan, unless sooner terminated by the participant as provided in Section 11 of the U.S. Plan.

5.Payroll Deductions and Other Approved Contributions.

(a)Except to the extent otherwise determined by the Board, payroll deductions shall be made in accordance with Section 6 of the U.S. Plan. The Board may, at its discretion, approve other methods of contributions including, without limitation, check, cash or standing order of the Participant’s individual bank account.

(b)The amounts so collected shall be credited to the participant’s individual book account under the Sub-Plan, initially in the currency in which paid by the Affiliate until converted into U.S. Dollars. Accordingly, all purchases of Common Stock under the Sub-Plan are to be made with the U.S. Dollars into which the payroll deductions for the Offering Period or other approved contributions have been converted. The amounts collected from a participant may be commingled with the general assets of the Company or the Affiliate and may be used for general corporate purposes, except as otherwise required by local law.

(c)For purposes of determining the number of shares purchasable by a participant, the payroll deductions or other approved contributions credited to each participant’s book account during each Exercise Period shall be converted into U.S. Dollars on the Exercise Date for that Exercise Period on the basis of the exchange rate in effect on such date. The Board shall have the absolute discretion to determine the applicable exchange rate to be in effect for each Exercise Date by any reasonable method (including, without limitation, the exchange rate actually used by the Company for its intra-Company financial transactions for the month of such transfer). Any changes or fluctuations in the exchange rate at which the payroll deductions or other approved contributions collected on the participant’s behalf are converted into U.S. Dollars on each Exercise Date shall be borne solely by the participant.

6.Grant of Option. The grant of the option and the purchase price of the option shall be in accordance with Section 7 of the U.S. Plan.

7.Exercise of Option. The exercise of the option shall be in accordance with Section 8 of the U.S. Plan.

Notwithstanding any provision of the U.S. Plan or this Sub-Plan to the contrary, in order to comply with the laws in other countries in which the Company and its Subsidiaries operate or have participants, the Company, by action of its duly authorized officers, in their sole discretion, shall have the power and authority at any time to establish “offering document” and similar addendums to this Sub-Plan to modify administrative procedures and other terms and procedures, to the extent such actions may be necessary or advisable and take any action that it deems advisable to obtain approval or comply with any necessary local governmental regulatory exemptions or approvals.

Accounting Policies [Abstract]

Business and Summary Of Significant Accounting Policies

Business and Summary of Significant Accounting Policies

Business

Autodesk, Inc. (“Autodesk” or the “Company”) is a world leading design software and services company, offering customers productive business solutions through powerful technology products and services. The Company serves customers in the architecture, engineering, and construction; manufacturing; and digital media, consumer, and entertainment industries. The Company’s sophisticated software products enable its customers to experience their ideas before they are real by allowing them to imagine, design, and create their ideas and to visualize, simulate, and analyze real-world performance early in the design process by creating digital prototypes. These capabilities allow Autodesk’s customers to foster innovation, optimize and improve their designs, help save time and money, improve quality, and collaborate with others. Autodesk software products are sold globally, both directly to customers and through a network of resellers and distributors.

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of Autodesk and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.

Reclassifications

During the first quarter of fiscal 2014, Autodesk combined maintenance revenue and cloud services offering-related revenue into one category named “Subscription.” As a result, revenue and cost of revenue related to cloud service offerings previously reflected in “License and other revenue” and “Cost of license and other revenue” were reclassified to “Subscription revenue” and “Cost of subscription revenue.” These revenues and expenses have been reclassified in the Consolidated Statements of Operations for fiscal year 2013 to conform to the current period presentation as follows:

	Fiscal year ended January 31,
	2013
Reclassifications within revenue:
Decrease to License and other revenue	$	(26.5	)
Increase to Subscription revenue	26.5
Reclassifications within cost of revenue:
Decrease to Cost of license and other revenue	$	(32.1	)
Increase to Cost of subscription revenue	32.1

During the second quarter of fiscal 2015, Autodesk elected to present amortization of purchased customer relationships, trade names, patents, and user lists as a separate line item within operating expenses. As a result, amortization previously reflected in “General and Administrative” expense was reclassified to “Amortization of Purchased Intangibles" within Operating Expenses. These expenses have been reclassified in the Consolidated Statements of Operations for fiscal years 2014 and 2013 to conform to the current period presentation as follows:

	Fiscal year ended January 31,
	2014			2013
Reclassifications within operating expenses:
(Decrease) to general and administrative	$	(36.5	)	$	(42.1	)
Increase to amortization of purchased intangibles	36.5			42.1

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in Autodesk’s consolidated financial statements and notes thereto. These estimates are based on information available as of the date of the consolidated financial statements. On a regular basis, management evaluates these estimates and assumptions. Actual results may differ materially from these estimates.

Examples of significant estimates and assumptions made by management involve the determination of the fair value of acquired assets and liabilities, goodwill, financial instruments, long-lived assets and other intangible assets, the realizability of deferred tax assets, and the fair value of stock awards. The Company also makes assumptions, judgments, and estimates in determining the accruals for uncertain tax positions, variable compensation, partner incentive programs, product returns reserves, allowances for doubtful accounts, asset retirement obligations, and legal contingencies.

Foreign Currency Translation and Transactions

The assets and liabilities of Autodesk’s foreign subsidiaries are translated from their respective functional currencies into U.S. dollars at the rates in effect at the balance sheet date, and revenue and expense amounts are translated at exchange rates that approximate those rates in effect during the period in which the underlying transactions occur. Foreign currency translation adjustments are recorded as other comprehensive income (loss).

Gains and losses realized from foreign currency transactions, those transactions denominated in currencies other than the foreign subsidiary’s functional currency, are included in interest and other income, net. Monetary assets and liabilities are remeasured using foreign currency exchange rates at the end of the period, and non-monetary assets are remeasured based on historical exchange rates.

Derivative Financial Instruments

Under its risk management strategy, Autodesk uses derivative instruments to manage its short-term exposures to fluctuations in foreign currency exchange rates which exist as part of ongoing business operations. Autodesk’s general practice is to hedge a majority of transaction exposures denominated in euros, Japanese yen, Swiss francs, British pounds, Canadian dollars, and Australian dollars. These instruments have maturities between one to 12 months in the future. Autodesk does not enter into any derivative instruments for trading or speculative purposes.

The bank counterparties in all contracts expose Autodesk to credit-related losses in the event of their nonperformance. However, to mitigate that risk, Autodesk only contracts with counterparties who meet the Company’s minimum requirements under its counterparty risk assessment process. Autodesk monitors ratings, credit spreads, and potential downgrades on at least a quarterly basis. Based on Autodesk’s on-going assessment of counterparty risk, the Company will adjust its exposure to various counterparties. Autodesk generally enters into master netting arrangements, which reduce credit risk by permitting net settlement of transactions with the same counterparty. However, Autodesk does not have any master netting arrangements in place with collateral features.

Autodesk accounts for its derivative instruments as either assets or liabilities on the balance sheet and carries them at fair value. Gains and losses resulting from changes in fair value are accounted for depending on the use of the derivative and whether it is designated and qualifies for hedge accounting. Derivatives that do not qualify for hedge accounting are adjusted to fair value through earnings. See Note 2, "Financial Instruments" for information regarding Autodesk's hedging activities.

Cash and Cash Equivalents

Autodesk considers all highly liquid investments with insignificant interest rate risk and remaining maturities of three months or less at the date of purchase to be cash equivalents. Cash equivalents are recorded at cost, which approximates fair value.

Marketable Securities

Marketable securities are stated at fair value. Marketable securities maturing within one year that are not restricted are classified as current assets.

Autodesk determines the appropriate classification of its marketable securities at the time of purchase and re-evaluates such classification as of each balance sheet date. Autodesk carries all “available-for-sale securities” at fair value, with unrealized gains and losses, net of tax, reported in stockholders’ equity until disposition or maturity. Autodesk carries all “trading securities” at fair value, with unrealized gains and losses, recorded in “Interest and other income, net” in the Company’s Consolidated Statements of Operations.

All of Autodesk’s marketable securities are subject to a periodic impairment review. The Company recognizes an impairment charge when a decline in the fair value of its investments below the cost basis is judged to be other-than-temporary. Autodesk considers various factors in determining whether to recognize an impairment charge, including the length of time and extent to which the fair value has been less than Autodesk’s cost basis, the financial condition and near-term prospects of the investee, and Autodesk’s intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery in the market value. Autodesk did not record any other-than temporary impairment charges during fiscal years ended January 31, 2015, 2014, and 2013. For additional information, see “Concentration of Credit Risk” within this Note 1 and Note 2, “Financial Instruments.”

Accounts Receivable, Net

Accounts receivable, net, consisted of the following as of January 31:

	2015			2014
Trade accounts receivable	$	495.4		$	464.6
Less: Allowance for doubtful accounts	(6.3		)	(4.9		)
Product returns reserve	(2.6		)	(4.0		)
Partner programs and other obligations	(27.6		)	(32.0		)
Accounts receivable, net	$	458.9		$	423.7

Allowances for uncollectible trade receivables are based upon historical loss patterns, the number of days that billings are past due, and an evaluation of the potential risk of loss associated with problem accounts.

The product returns reserves are based on historical experience of actual product returns, estimated channel inventory levels, the timing of new product introductions, channel sell-in for applicable markets, and other factors.

As part of the indirect channel model, Autodesk has a partner incentive program that uses quarterly attainment of monetary rewards to motivate distributors and resellers to achieve mutually agreed upon business goals in a specified time period. A portion of these incentives reduce license and other revenue in the current period. The remainder, which relates to incentives on our Subscription Program, is recorded as a reduction to deferred revenue in the period the maintenance transaction is billed and subsequently recognized as a reduction to maintenance revenue over the contract period. These incentive balances do not require significant assumptions or judgments. The reserves associated with the partner incentive program are treated on the consolidated balance sheet as either contra account receivable (when due to distributors and direct resellers) or accounts payable (when due to indirect resellers).

Concentration of Credit Risk

Autodesk places its cash, cash equivalents, and marketable securities in highly liquid instruments with, and in the custody of, diversified financial institutions globally with high credit ratings and limits the amounts invested with any one institution, type of security, and issuer.

Geographical concentrations of consolidated cash, cash equivalents, and marketable securities held by Autodesk as of January 31:

	2015		2014
United States	19	%	25	%
Other Americas	1	%	1	%
Europe, Middle East, and Africa (“EMEA”)	56	%	57	%
Asia Pacific (“APAC”)	24	%	17	%

Autodesk’s primary commercial banking relationship is with Citigroup Inc. and its global affiliates. Citibank, N.A., an affiliate of Citigroup, is one of the lead lenders and an agent in the syndicate of Autodesk’s $400.0 million line of credit facility. It is Autodesk’s policy to limit the amounts invested with any one institution by type of security and issuer.

Autodesk’s accounts receivable are derived from sales to a large number of resellers, distributors, and direct customers in the Americas; EMEA; and APAC geographies. Autodesk performs ongoing evaluations of these partners' financial condition and limits the amount of credit extended when deemed necessary, but generally does not require collateral from such parties. Total sales to the Company's largest distributor Tech Data Corporation, and its global affiliates (“Tech Data”), accounted for 25%, 24%, and 23% of Autodesk's net revenue for fiscal years ended January 31, 2015, 2014, and 2013, respectively. The majority of the net revenue from sales to Tech Data relates to Autodesk's Platform Solutions and Emerging Business ("PSEB") segment and is for sales made outside of the United States. In addition, Tech Data accounted for 22% and 24% of trade accounts receivable at January 31, 2015 and 2014, respectively.

Computer Equipment, Software, Furniture, and Leasehold Improvements, Net

Computer equipment, software, and furniture are depreciated using the straight-line method over the estimated useful lives of the assets, which range from three to five years. Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated useful lives or the lease term. Depreciation expense was $52.1 million in fiscal 2015, $47.2 million in fiscal 2014, and $45.6 million in fiscal 2013.

Computer equipment, software, furniture, leasehold improvements and the related accumulated depreciation at January 31 were as follows:

	2015			2014
Computer hardware, at cost	$	194.0		$	163.0
Computer software, at cost	84.9			80.9
Leasehold improvements, land, and buildings, at cost	176.3			163.7
Furniture and equipment, at cost	53.0			51.7
Computer software, hardware, leasehold improvements, furniture, and equipment, at cost	508.2			459.3
Less: Accumulated depreciation	(349.0		)	(329.0		)
Computer software, hardware, leasehold improvements, furniture, and equipment, net	$	159.2		$	130.3

Costs incurred for computer software developed or obtained for internal use are capitalized for application development activities, if material, and immediately expensed for preliminary project activities and post-implementation activities. These capitalized costs are amortized over the software’s expected useful life, which is generally three years. During fiscal 2015, Autodesk wrote-off $25.8 million of fully depreciated assets.

Software Development Costs

Software development costs incurred prior to the establishment of technological feasibility are included in research and development expenses. Autodesk defines establishment of technological feasibility as the completion of a working model. Software development costs incurred subsequent to the establishment of technological feasibility through the period of general market availability of the products are capitalized and generally amortized over a three year period, if material. Autodesk had no material capitalized software development costs at January 31, 2015 and January 31, 2014.

Other Intangible Assets, Net

Other intangible assets include developed technologies, customer relationships, trade names, patents, user lists, and the related accumulated amortization. These assets are shown as “Developed technologies, net” and as part of “Other assets” in the Consolidated Balance Sheet. The majority of Autodesk’s other intangible assets are amortized to expense over the estimated economic life of the product, which ranges from one to ten years. Amortization expense for developed technologies, customer relationships, trade names, patents, and user lists was $92.9 million in fiscal 2015, $80.7 million in fiscal 2014 and $82.0 million in fiscal 2013.

Other intangible assets and related accumulated amortization at January 31 were as follows:

	2015			2014
Developed technologies, at cost	$	538.4		$	462.4
Customer relationships, trade names, patents, and user lists, at cost (1)	348.9			268.1
	887.3			730.5
Less: Accumulated amortization	(715.4		)	(626.2		)
Other intangible assets, net	$	171.9		$	104.3

_______________ 

(1) Included as a net balance in “Other assets” in the Consolidated Balance Sheet. Customer relationships and trade names include the effects of foreign currency translation.

The weighted average amortization period for developed technologies, customer relationships, and trade names during fiscal 2015 was 4.2 years. Expected future amortization expense for developed technologies, customer relationships, trade names, patents, and user lists for each of the fiscal years ended thereafter is as follows:

	Fiscal Year ended January 31,
2016	$	73.2
2017	49.7
2018	24.0
2019	15.5
2020	5.3
Thereafter	4.2
Total	$	171.9

Goodwill

Goodwill consists of the excess of the consideration transferred over the fair value of net assets acquired in business combinations. Autodesk assigns goodwill to the reporting unit associated with each business combination, and tests goodwill for impairment annually in its fourth fiscal quarter or more often if circumstances indicate a potential impairment. For purposes of the goodwill impairment test, a reporting unit is an operating segment or one level below.

Autodesk has the option to perform an assessment of qualitative factors of impairment (“optional assessment”) prior to necessitating a two-step quantitative impairment test. Should the optional assessment be utilized for any given fiscal year, qualitative factors to consider include cost factors; financial performance; legal, regulatory, contractual, political, business, or other factors; entity specific factors; industry and market considerations, macroeconomic conditions, and other relevant events and factors affecting the reporting unit. If, after assessing the totality of events or circumstances, it is more likely than not that the fair value of the reporting unit is greater than its carrying value, then performing the two-step impairment test is unnecessary.

Therefore, the two-step quantitative impairment test is necessary when either Autodesk does not utilize the optional assessment or, as a result of the optional assessment, it is not more likely than not that the fair value of the reporting unit is greater than its carrying value. In performing the two-step impairment test, Autodesk uses discounted cash flow models which include assumptions regarding projected cash flows. Variances in these assumptions could have a significant impact on Autodesk's conclusion as to whether goodwill is impaired, or the amount of any impairment charge. Impairment charges, if any, result from instances where the fair values of net assets associated with goodwill are less than their carrying values. As changes in business conditions and assumptions occur, Autodesk may be required to record impairment charges. The process of evaluating the potential impairment of goodwill is subjective and requires significant judgment at many points during the analysis. The value of Autodesk’s goodwill could also be impacted by future adverse changes such as: (i) declines in Autodesk’s actual financial results, (ii) a sustained decline in Autodesk’s market capitalization, (iii) significant slowdown in the worldwide economy or the industries Autodesk serves, or (iv) changes in Autodesk’s business strategy or internal financial forecast results.

For the fiscal 2015 annual goodwill impairment testing, Autodesk had five reporting units: PSEB, Manufacturing ("MFG"), Architecture, Engineering, and Construction ("AEC"), Media and Entertainment ("M&E"), and Delcam.

For the annual impairment assessment in fiscal 2015, Autodesk utilized the optional assessment for Delcam. Based on a review of the qualitative factors described above, we determined that for our Delcam reporting unit, it was more likely than not that the fair value of the reporting unit exceeded the carrying value. As a result, we concluded that performing the two-step impairment test was not necessary for Delcam.

For each of the remaining four reporting units, Autodesk did not utilize the optional assessment but rather performed the quantitative two-step impairment test. In performing the quantitative two-step test, Autodesk used a discounted cash flow model which included assumptions regarding projected cash flows. Based on this testing, Autodesk determined that the fair value was substantially in excess of the carrying value for each of the four reporting units and therefore the goodwill of each reporting unit was not impaired during the fiscal year ended January 31, 2015. In addition, Autodesk did not recognize any goodwill impairment losses in fiscal 2014 or 2013.

The change in the carrying amount of goodwill during the fiscal year ended January 31, 2015 is as follows:

Purchase accounting adjustments reflect revisions made to the Company’s preliminary purchase price allocations during fiscal 2015 and 2014.

Impairment of Long-Lived Assets

At least annually or more frequently as circumstances dictate, Autodesk reviews its long-lived assets for impairment whenever impairment indicators exist.  Autodesk continually monitors events and changes in circumstances that could indicate the carrying amounts of its long-lived assets may not be recoverable. When such events or changes in circumstances occur, Autodesk assesses recoverability of these assets.  Recoverability is measured by comparison of the carrying amounts of the assets to the future undiscounted cash flows the assets are expected to generate.  If the long-lived assets are considered to be impaired, the impairment to be recognized is equal to the amount by which the carrying value of the assets exceeds its fair market value. Autodesk did not recognize any impairment of long-lived assets during the fiscal years ended January 31, 2015, 2014, and 2013, respectively.

In addition to the recoverability assessments, Autodesk routinely reviews the remaining estimated useful lives of its long-lived assets. Any reduction in the useful life assumption will result in increased depreciation and amortization expense in the quarter when such determinations are made, as well as in subsequent quarters.

Deferred Tax Assets

Deferred tax assets arise primarily from tax credits, net operating losses, and timing differences for reserves, accrued liabilities, stock options, deferred revenue, purchased technologies, and capitalized intangibles, partially offset by the establishment of U.S. deferred tax liabilities on unremitted earnings from certain foreign subsidiaries, and valuation allowances against U.S. and foreign deferred tax assets. We perform a quarterly assessment of the recoverability of these net deferred tax assets and believe that we will generate sufficient future taxable income in appropriate tax jurisdictions to realize the net deferred tax assets. They are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to reverse. Valuation allowances are established when necessary to reduce gross deferred tax assets to the amount “more likely than not” expected to be realized.

Revenue Recognition

Autodesk recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed or determinable, and collection is probable.

For multiple element arrangements containing only software and software-related elements, Autodesk allocates the sales price among each of the deliverables using the residual method, under which revenue is allocated to undelivered elements based on their vendor-specific objective evidence (“VSOE”) of fair value. VSOE is the price charged when an element is sold separately or a price set by management with the relevant authority. If Autodesk does not have VSOE of an undelivered element, revenue recognition is deferred on the entire sales arrangement until all elements for which Autodesk does not have VSOE are delivered. If Autodesk does not have VSOE for undelivered maintenance or services, the revenue for the arrangement is recognized over the longest contractual service period in the arrangement. Revenue recognition for significant lines of business is discussed further below.

For multiple element arrangements involving non-software elements, including cloud subscription services, our revenue recognition policy is based upon the accounting guidance contained in ASC 605, Revenue Recognition. For these arrangements, Autodesk first allocates the total arrangement consideration based on the relative selling prices of the software group of elements as a whole and the non-software elements. Autodesk then further allocates consideration within the software group to the respective elements within that group using the residual method as described above. Autodesk exercises judgment and uses estimates in connection with the determination of the amount of revenue to be recognized in each accounting period.

Autodesk allocates the total arrangement consideration among the various elements based on a selling price hierarchy. The selling price for a deliverable is based on its VSOE if available, third-party evidence ("TPE") if VSOE is not available, or the best estimated selling price ("BESP") if neither VSOE nor TPE is available. BESP represents the price at which Autodesk would transact for the deliverable if it were sold regularly on a standalone basis. To establish BESP for those elements for which neither VSOE nor TPE are available, Autodesk performs a quantitative analysis of pricing data points for historical standalone transactions involving such elements for a twelve-month period. As part of this analysis, Autodesk monitors and evaluates the BESP against actual pricing to ensure that it continues to represent a reasonable estimate of the standalone selling price, considering several other external and internal factors including, but not limited to, pricing and discounting practices, contractually stated prices, the geographies in which Autodesk offers products and services, and the type of customer (i.e. distributor, value-added reseller, and direct end user, among others). Autodesk analyzes BESP at least annually or on a more frequent basis if a significant change in our business necessitates a more timely analysis, or if significant selling price variances are experienced.

Autodesk’s assessment of likelihood of collection is also a critical element in determining the timing of revenue recognition. If collection is not probable, the revenue will be deferred until the earlier of when collection is deemed probable or cash is received.

License and other revenue are comprised of two components: (1) all forms of product license revenue and (2) other revenue.

(1) All Forms of Product License Revenue

Product license revenue includes: software license revenue from the sale of new seat licenses and upgrades and product revenue for Creative Finishing.

(2) Other Revenue

Other revenue includes revenue from consulting, training, Autodesk Developers Network, and Creative Finishing customer support, and is recognized over time, as the services are performed.

Autodesk's Subscription revenue consists of two components: maintenance revenue for our software products and revenue for our cloud service offerings, including Autodesk 360. Autodesk's maintenance program provides our commercial and educational customers of perpetual products with a cost effective and predictable budgetary option to obtain the productivity benefits of our new releases and enhancements when and if released during the term of their contracts. Under Autodesk's maintenance program, customers are eligible to receive unspecified upgrades when and if available, downloadable training courses, and online support. Autodesk recognizes maintenance revenue ratably over the term of the maintenance agreement, which is generally between one and three years but can occasionally be as long as five years. Revenue for Autodesk's cloud service offerings is recognized ratably over the contract term commencing with the date Autodesk's service is made available to customers and all other revenue recognition criteria have been satisfied.

Taxes Collected from Customers

Autodesk nets taxes collected from customers against those remitted to government authorities in the consolidated financial statements. Accordingly, taxes collected from customers are not reported as revenue.

Shipping and Handling Costs

Shipping and handling costs are included in cost of revenue for all periods presented.

Stock-based Compensation Expense

The following table summarizes stock-based compensation expense for fiscal 2015, 2014, and 2013, respectively, as follows:

	Fiscal Year Ended January 31,
	2015			2014			2013
Cost of license and other revenue	$	4.6		$	3.8		$	3.7
Cost of subscription	4.3			2.2			1.5
Marketing and sales	72.4			58.6			64.3
Research and development	56.0			43.7			61.8
General and administrative	28.3			23.9			25.0
Stock-based compensation expense related to stock awards and ESP Plan purchases	165.6			132.2			156.3
Tax benefit	(45.2		)	(36.4		)	(35.5		)
Stock-based compensation expense related to stock awards and ESP Plan purchases, net	$	120.4		$	95.8		$	120.8

Autodesk determines the grant-date fair value of its share-based payment awards using a Black-Scholes Merton Option ("BSM") pricing model or the quoted stock price on the date of grant, unless the awards are subject to market conditions, in which case Autodesk uses a binomial-lattice model (e.g., Monte Carlo simulation model). The Monte Carlo simulation model utilizes multiple input variables to estimate the probability that market conditions will be achieved. Autodesk uses the following assumptions to estimate the fair value of stock-based awards:

	Fiscal Year Ended		Fiscal Year Ended		Fiscal Year Ended
	January 31, 2015		January 31, 2014		January 31, 2013
	Performance Stock Unit (1)	ESP Plan	Performance Stock Unit (1)	ESP Plan	Stock Option (2)	ESP Plan
Range of expected volatilities	30%	29 - 33%	34%	27 - 36%	41 - 45%	41 - 44%
Range of expected lives (in years)	N/A	0.5 - 2.0	N/A	0.5 - 2.0	3.6 - 4.6	0.5 - 2.0
Expected dividends	—%	—%	—%	—%	—%	—%
Range of risk-free interest rates	0.1%	0.0 - 0.6%	0.1%	0.1 - 0.4%	0.5 - 0.8%	0.1 - 0.3%

 _______________

(1) Autodesk did not grant PSUs in fiscal 2013 that were subject to market conditions.

(2) Autodesk did not grant stock options in fiscal 2015 or 2014.

Autodesk estimates expected volatility for stock-based awards based on the average of the following two measures. The first is a measure of historical volatility in the trading market for the Company’s common stock, and the second is the implied volatility of traded forward call options to purchase shares of the Company’s common stock. The expected volatility for PSUs subject to market conditions includes the expected volatility of Autodesk's peer companies within the S&P Computer Software Select Index.

Autodesk estimates the expected life of stock-based awards using both exercise behavior and post-vesting termination behavior as well as consideration of outstanding options.

Autodesk did not pay cash dividends in fiscal 2015, 2014, or 2013 and does not anticipate paying any cash dividends in the foreseeable future. Consequently, an expected dividend yield of zero is used in the Black-Scholes-Merton option pricing model and the Monte Carlo simulation model.

The risk-free interest rate used in the BSM option pricing model and the Monte Carlo simulation model for stock-based awards is the historical yield on U.S. Treasury securities with equivalent remaining lives.

Autodesk recognizes expense only for the stock-based awards that are ultimately expected to vest. Therefore, Autodesk has developed an estimate of the number of awards expected to cancel prior to vesting (“forfeiture rate”). The forfeiture rate is estimated based on historical pre-vest cancellation experience and is applied to all stock-based awards. The Company estimates forfeitures at the time of grant and revises those estimates in subsequent periods if actual forfeitures differ from those estimates.

Advertising Expenses

Advertising costs are expensed as incurred. Total advertising expenses incurred were $23.9 million in fiscal 2015, $15.6 million in fiscal 2014, and $15.6 million in fiscal 2013.

Net Income Per Share

Basic net income per share is computed based on the weighted average number of shares of common stock outstanding for the period, excluding stock options and restricted stock units. Diluted net income per share is computed based upon the weighted average shares of common shares outstanding for the period and potentially dilutive common shares, including the effect of stock options and restricted stock units under the treasury stock method.

Defined Benefit Pension Plans

The funded status of Autodesk's defined benefit pension plans is recognized in the Consolidated Balance Sheets. The funded status is measured as the difference between the fair value of plan assets and the projected benefit obligation for the fiscal years presented. The projected benefit obligation represents the actuarial present value of benefits expected to be paid upon retirement based on employee services already rendered and estimated future compensation levels. The fair value of plan assets represents the current market value of Autodesk's cumulative company and participant contributions made to the various plans in effect.

Net periodic benefit cost is recorded in the Consolidated Statements of Operations and includes service cost, interest cost, expected return on plan assets, amortization of prior service costs, and gains or losses previously recognized as a component of other comprehensive income. Certain events, such as changes in the employee base, plan amendments, and changes in actuarial assumptions may result in a change in the defined benefit obligation and the corresponding change to other comprehensive income.

Gains and losses and prior service costs not recognized as a component of net periodic benefit cost in the Consolidated Statements of Operations as they arise are recognized as a component of other comprehensive income in the Consolidated Statements of Comprehensive Income. Those gains and losses and prior service costs are subsequently amortized as a component of net periodic benefit cost over the average remaining service lives of the plan participants using a corridor approach to determine the portion of gain or loss subject to amortization.

The measurement of projected benefit obligations and net periodic benefit cost is based on estimates and assumptions that reflect the terms of the plans and use participant-specific information such as compensation, age and years of services, as well as certain assumptions, including estimates of discount rates, expected return of plan assets, rate of compensation increases, interest rates, and mortality rates.

Accounting Standards in Fiscal 2015

With the exception of those discussed below, there have been no recent changes in accounting pronouncements issued by the FASB or adopted by the Company during the fiscal year ended January 31, 2015, that are of significance, or potential significance, to the Company.

Accounting Standards Adopted

Effective February 1, 2014, Autodesk prospectively adopted FASB's Accounting Standards Update (“ASU”) 2013-11 regarding ASC Topic 740 “Income Tax.” This ASU clarifies the guidance on the presentation of an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the consolidated financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. The adoption of this ASU resulted in an $81.9M reduction of both our long term taxes payable and long-term deferred tax assets as of January 31, 2015.

Recently Issued Accounting Standards

On May 28, 2014, the FASB issued ASU 2014-09 regarding ASC Topic 606 “Revenue from Contracts with Customers.” This ASU provides principles for recognizing revenue for the transfer of promised goods or services to customers with the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU will be effective for Autodesk’s fiscal year beginning February 1, 2017. Early adoption is not permitted. Autodesk is currently evaluating the accounting, transition, and disclosure requirements of the standard and cannot currently estimate the financial statement impact of adoption.

Retirement Benefit Plans

Retirement Benefit Plans

Pretax Savings Plan

Autodesk has a 401(k) plan that covers nearly all U.S. employees. Eligible employees may contribute up to 50% of their pretax salary, subject to limitations mandated by the Internal Revenue Service. Autodesk makes voluntary cash contributions and matches a portion of employee contributions in cash. Autodesk’s contributions were $11.2 million in fiscal 2015, $8.1 million in fiscal 2014, and $7.9 million in fiscal 2013. Autodesk does not allow participants to invest in Autodesk common stock through the 401(k) plan.

Defined Benefit Pension Plans

Autodesk maintains certain defined benefit pension plans to employees primarily located in countries outside of the U.S, particularly the United Kingdom, Switzerland, and Japan. The Company deposits funds for specific plans, consistent with the requirements of local law, with insurance companies, third-party trustees, or into government-managed accounts, and accrues for the unfunded portion of the obligation, where material. Depending on the design of the plan, local customs, and market circumstances, the liabilities of a plan may exceed qualified plan assets.

Benefit obligation and plan assets

The changes in the projected benefit obligations and plan assets for the plans described above were as follows:

	Fiscal year ended January 31,
	2015			2014
Beginning projected benefit obligation	$	62.2		$	61.5
Service cost	4.6			5.4
Interest cost	3.9			1.1

Business combinations	60.2			—
Ending fair value of plan assets	$	104.2		$	40.7
Funded status	$	(40.5	)	$	(21.5	)

Amounts included within the business combinations line above represent plan assets and liabilities assumed under the acquisition of Delcam.

The amounts recognized on the consolidated balance sheets at the end of each period were as follows:

	Fiscal Year Ended January 31,
	2015		2014
Other long-term liabilities	$	40.5	$	21.5
Accumulated other comprehensive loss, before tax	26.6		8.7
Net amount recognized	$	67.1	$	30.2

On a worldwide basis, our defined benefit plans were 72% funded as of January 31, 2015. Funded status is not indicative of our ability to pay ongoing pension benefits or of Autodesk's obligation to fund retirement accounts.

As of January 31, 2015, the aggregate accumulated benefit obligation was $124.3 million for the pension plans ($45.3 million as of January 31, 2014). Included in the aggregate data in the following tables are the amounts applicable to our defined benefit plans, with accumulated benefit obligations in excess of plan assets, as well as plans with projected benefit obligations in excess of plan assets. Amounts related to such plans at the end of each period were as follows:

	Fiscal Year Ended January 31,
	2015		2014
Plans with accumulated benefit obligations in excess of plan assets:
Accumulated benefit obligations	$	124.0	$	45.3
Plan Assets	103.9		40.7
Plans with projected benefit obligations in excess of plan assets:
Projected benefit obligations	$	144.7	$	62.2
Plan Assets	104.2		40.7

Pension Plan Assets

The investments of the plans are managed by insurance companies or third-party investment managers selected by Autodesk's Trustees, consistent with regulations or market practice of the country where the assets are invested. Investments managed by qualified insurance companies or third-party investment managers under standard contracts follow local regulations, and Autodesk is not actively involved in their investment strategies.

Pension plan assets measured at fair value on a recurring basis consisted of the following investment categories at the end of each period as follows:

	Fiscal Year Ended January 31,
	2015								2014
	Level 1		Level 2		Level 3		Total		Total
Investment fund	$	55.7	$	4.9	$	—	$	60.6	$	—
Insurance contracts	—		43.5		—		43.5		40.2
Total assets measured at fair value	55.7		48.4		—		104.1		40.2
Cash	0.1		—		—		0.1		0.5
Total pension plan assets at fair value	$	55.8	$	48.4	$	—	$	104.2	$	40.7

The assets held in the investment fund in the preceding table are invested in a diversified growth fund actively managed by Russell Investments in association with Aon Hewitt. The objective of the fund is to generate capital appreciation on a long-term basis through a diversified portfolio of investments. The fund aims to deliver equity-like returns in the medium to long term with around two-thirds the volatility of equity markets. The fair value of the assets held in the investment fund classified as Level 1 are priced daily using observable inputs for identical assets. The fair value of the assets held in the investment fund classified as Level 2 are priced monthly at net asset value with quarterly redemption attributes.

The insurance contracts in the preceding table represent the immediate cash surrender value of assets managed by qualified insurance companies. Autodesk does not have control over the target allocation or visibility of the investment strategies of those investments. Insurance contracts and investments held by insurance companies made up 42% of total plan assets as of January 31, 2015 (99% as of January 31, 2014).

Estimated Future Benefit Payments

Estimated benefit payments over the next 10 fiscal years are as follows:

	Pension Benefits
2016	$	3.5
2017	3.4
2018	3.5
2019	3.3
2020	3.1
2021-2025	17.5

Funding Expectations

Our expected required funding for the plans during fiscal 2016 is approximately $4.6 million.

Net Periodic Benefit Cost

The components of net periodic pension cost for the defined benefit pension plans for fiscal 2015, 2014, and 2013 are as follows:

	Fiscal Year Ended January 31,
	2015			2014			2013
Service cost for benefits earned during the period	$	4.6		$	5.4		$	4.5
Interest cost on projected benefit obligation	3.9			1.1			1.3
Expected return on plan assets	(4.6		)	(0.8		)	(0.8		)
Amortization of prior service credit	(0.1		)	(0.1		)	(0.1		)
Amortization of loss	0.6			1.0			0.7
Net periodic benefit cost	$	4.4		$	6.6		$	5.6

Amounts Recorded in OCI

The components of other comprehensive income for the defined benefit pension plans before taxes for fiscal 2015, 2014, and 2013 are as follows:

	Fiscal Year Ended January 31,
	2015			2014			2013
Net loss (gain) for period	$	18.4		$	(3.9	)	$	6.3
Amortization of prior service credit	0.1			0.1			0.1
Amortization of net loss	(0.6		)	(1.0		)	(0.7		)
Other comprehensive loss (income)	$	17.9		$	(4.8	)	$	5.7

Amounts Recorded in AOCI

The amounts recorded in accumulated other comprehensive income loss before taxes at the end of each period were as follows:

	Fiscal Year Ended January 31,
	2015			2014
Net prior service credit	$	(1.8	)	$	(1.9	)
Net actuarial loss	28.4			10.6
Accumulated other comprehensive loss, before tax	$	26.6		$	8.7

The estimated amounts that will be amortized from AOCI into net periodic benefit cost over the next fiscal year for the qualified defined benefit pension plan and other benefit plans are as follows:

	Pension Benefits
Amortization of prior service credit	$	0.1
Amortization of the net loss	(1.5		)
Total amortization	$	(1.4	)

Assumptions

Weighted average actuarial assumptions used to determine costs for the plans for each period were as follows:

	Fiscal Year Ended January 31,
	2015		2014		2013
Discount rate	3.3	%	2.3	%	1.8	%
Expected long-term rate of return on plan assets	3.9	%	1.9	%	2.0	%
Rate of compensation increase	2.2	%	2.2	%	2.1	%

The weighted-average expected long-term rate of return for the plan assets is 3.9%. The weighted-average expected long-term rate of return on plan assets is based on the interest rates guaranteed under the insurance contracts, and the expected rate of return appropriate for each category of assets weighted for the distribution within the diversified investment fund. The assumptions used for the plans are based upon customary rates and practices for the location of the plans. Factors such as asset class allocations, long-term rates of return (actual and expected), and results of periodic asset liability modeling studies are considered when constructing the long-term rate of return assumption for our pension plans.

Weighted average actuarial assumptions used to determine benefit obligations for the plans at the end of each period were as follows:

	Fiscal Year Ended January 31,
	2015		2014		2013
Discount rate	2.4	%	2.2	%	1.8	%
Rate of compensation increase	1.2	%	2.2	%	2.0	%

In selecting the appropriate discount rate for the plans, the Company uses country-specific information, adjusted to reflect the duration of the particular plan.The discount rate was based on highly rated long-term bond indexes and yield curves that match the duration of the plan’s benefit obligations.

Defined Contribution Plans

Autodesk also provides defined contribution plans in certain foreign countries where required by statute. Autodesk’s funding policy for foreign defined contribution plans is consistent with the local requirements in each country. Autodesk’s contributions to these plans were $23.5 million in fiscal 2015, $22.3 million in fiscal 2014, and $21.5 million in fiscal 2013.

Other Plans

In addition, Autodesk offers a non-qualified deferred compensation plan to certain key employees whereby they may defer a portion (or all) of their annual compensation until retirement or a different date specified by the employee in accordance with terms of the plan. See Note 6, “Deferred Compensation,” for further discussion.

Equity [Abstract]

Stockholders' Equity

Stockholders' Equity

Preferred Stock

Under Autodesk’s Certificate of Incorporation, 2.0 million shares of preferred stock are authorized. At January 31, 2015, there were no preferred shares issued or outstanding. The Board of Directors has the authority to issue the preferred stock in one or more series and to fix rights, preferences, privileges, and restrictions, including dividends and the number of shares constituting any series or the designation of such series, without any further vote or action by the stockholders.

Common Stock Repurchase Programs

Autodesk has a stock repurchase program that is used to offset dilution from the issuance of stock under the Company’s employee stock plans and for such other purposes as may be in the interests of Autodesk and its stockholders, which has the effect of returning excess cash generated from the Company’s business to stockholders. Autodesk repurchased and retired 6.9 million shares in fiscal 2015 at an average repurchase price of $53.83 per share, 10.5 million shares in fiscal 2014 at an average repurchase price of $40.43 per share, and 12.5 million shares in fiscal 2013 at an average repurchase price of $34.50.

At January 31, 2015, 14.8 million shares remained available for repurchase under the repurchase program approved by the Board of Directors. The number of shares acquired and the timing of the purchases are based on several factors, including general market and economic conditions, the number of employee stock option exercises and stock issuances, the trading price of Autodesk common stock, cash on hand and available in the United States, cash requirements for acquisitions, and Company defined trading windows.

During fiscal year 2015, the Company reduced its current federal and state taxes payable by $0.5 million related to excess tax benefits from non-qualified stock options, offsetting additional paid-in capital. Pursuant to accounting standards related to stock-based compensation, the Company has unrecorded excess stock option tax benefits of $217.9 million as of January 31, 2015. These amounts will be credited to additional paid-in-capital when such amounts reduce cash taxes payable. Foreign pretax income was $302.5 million in fiscal 2015, $380.5 million in fiscal 2014, and $383.3 million in fiscal 2013.

The differences between the U.S. statutory rate and the aggregate income tax provision are as follows:

Significant components of Autodesk’s deferred tax assets and liabilities are as follows:

Research and development tax credit carryforwards	62.6			78.4

Effective February 1, 2014, Autodesk prospectively adopted FASB's Accounting Standards Update (“ASU”) 2013-11

regarding ASC Topic 740 “Income Tax.”  This ASU clarifies the guidance on the presentation of an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the consolidated financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. Research and development tax credit carryforwards and foreign tax credit carryforwards as of January 31, 2015 have been reduced by unrecognized tax benefits to the extent the tax credit carryforwards would be expected to offset tax liabilities in the event the uncertain tax positions are disallowed.

The valuation allowance increased by $3.6 million, $15.9 million, and $3.8 million in fiscal 2015, 2014, and 2013, respectively. The fiscal 2015, 2014, and 2013 changes in valuation allowance were primarily related to U.S. and Canadian deferred taxes.

Autodesk provides U.S. income taxes on the earnings of foreign subsidiaries, except to the extent subsidiaries' earnings are considered permanently reinvested outside the U.S. As of January 31, 2015, the cumulative amount of earnings upon which U.S. income taxes have not been provided was $1,809.4 million. The unrecognized deferred tax liability for these earnings was approximately $514.4 million.

Realization of the net deferred tax assets of $185.1 million is dependent upon the company's ability to generate future taxable income in appropriate tax jurisdictions to obtain benefit from the reversal of temporary differences, net operating loss carryforwards and tax credits. The amount of deferred tax assets considered realizable is subject to adjustment in future periods if estimates of future taxable income are reduced and Autodesk then determines that it is not more likely than not to realize such deferred tax assets.

As of January 31, 2015, Autodesk had $21.7 million of cumulative federal tax loss carryforwards and $354.3 million of cumulative state tax loss carryforwards, which may be available to reduce future income tax liabilities in certain jurisdictions. These federal and state tax loss carryforwards will expire beginning fiscal 2015 through fiscal 2034 and fiscal 2015 through fiscal 2034, respectively. Autodesk also had $7.4 million of cumulative UK tax loss carryforwards, which may be available to reduce future income tax liabilities indefinitely. Autodesk had $9.2 million of cumulative federal and state capital loss carryforwards as of January 31, 2015 which are available to offset future capital gains through fiscal 2018.

As of January 31, 2015, Autodesk had $104.7 million of cumulative federal research tax credit carryforwards, $54.8 million of cumulative California state research tax credit carryforwards, and $59.8 million of cumulative Canadian federal tax credit carryforwards, which may be available to reduce future income tax liabilities in the respective jurisdictions. The federal credit carryforwards will expire beginning fiscal 2020 through fiscal 2035, the state credit carryforwards may reduce future California income tax liabilities indefinitely, and the Canadian tax credit carryforwards will expire beginning fiscal 2024 through fiscal 2034. Autodesk also has $163.6 million of cumulative foreign tax credit carryforwards, which may be available to reduce future U. S. tax liabilities. The foreign tax credit will expire beginning fiscal 2019 through fiscal 2026.

Utilization of net operating losses and tax credits may be subject to an annual limitation due to ownership change limitations provided in the Internal Revenue Code and similar state provisions. This annual limitation may result in the expiration of net operating losses and credits before utilization.

As a result of certain business and employment actions and capital investments undertaken by Autodesk, income earned in certain Europe and Asia Pacific countries is subject to reduced tax rates through fiscal 2016 and 2020, respectively with extensions available with incremental business and employment actions. The net income tax benefits attributable to the tax status of these business arrangements are estimated to be $1.2 million ($0.01 basic net income per share) in fiscal 2015, $9.7 million ($0.04 basic net income per share) in fiscal 2014, and $6.6 million ($0.03 basic net income per share) in fiscal 2013. The income tax benefits were offset partially by accruals of U.S. income taxes on undistributed earnings, among other factors.

As of January 31, 2015, the company had $245.8 million of gross unrecognized tax benefits, of which $227.3 million would impact the effective tax rate, if recognized. It is possible that the amount of unrecognized tax benefits will change in the next twelve months; however an estimate of the range of the possible change cannot be made at this time.

A reconciliation of the beginning and ending amount of the gross unrecognized tax benefits is as follows:

	Fiscal Year Ended January 31,
	2015			2014			2013
Gross unrecognized tax benefits at the beginning of the fiscal year	$	222.1		$	212.7		$	201.1
Increases for tax positions of prior years	3.2			1.8			0.4
Decreases for tax positions of prior years	(2.5		)	(0.3		)	(0.4		)
Increases for tax positions related to the current year	33.2			15.3			17.8
Decreases relating to settlements with taxing authorities	(5.4		)	(4.6		)	(3.0		)
Reductions as a result of lapse of the statute of limitations	(4.8		)	(2.8		)	(3.2		)
Gross unrecognized tax benefits at the end of the fiscal year	$	245.8		$	222.1		$	212.7

It is the company's continuing practice to recognize interest and/or penalties related to income tax matters in income tax expense. Autodesk had $2.0 million, $2.8 million, and $1.9 million, net of tax benefit, accrued for interest and an immaterial amount accrued for penalties related to unrecognized tax benefits as of January 31, 2015, 2014, and 2013, respectively.

Autodesk and its subsidiaries are subject to income tax in the United States as well as numerous state and foreign jurisdictions. Autodesk's U.S. and state income tax returns for fiscal year 2003 through fiscal year 2015 remain open to examination. In addition, Autodesk files tax returns in multiple foreign taxing jurisdictions with open tax years ranging from fiscal year 2003 to 2015.

Employee and Director Stock Plans

Employee and Director Stock Plans

Stock Plans

As of January 31, 2015, Autodesk maintained two active stock plans for the purpose of granting equity awards to employees and to non-employee members of Autodesk’s Board of Directors: the 2012 Employee Stock Plan (as amended, the “2012 Employee Plan”), which is available only to employees, and the Autodesk 2012 Outside Directors’ Stock Plan (“2012 Directors' Plan”), which is available only to non-employee directors. Additionally, there are three expired or terminated plans with options outstanding. The exercise price of all stock options granted under these plans was equal to the fair market value of the stock on the grant date.

The 2012 Employee Plan was approved by Autodesk's stockholders and became effective on January 6, 2012. On January 14, 2014, Autodesk's stockholders approved amendments to the 2012 Employee Plan, which increased the number of shares reserved for issuance under the plan by 11.4 million shares and added additional performance goals to the plan. The 2012 Employee Plan replaced the 2008 Employee Stock Plan, as amended ("2008 Plan"), and no further equity awards may be granted under the 2008 Plan. The 2012 Employee Plan reserves up to 32.6 million shares which includes 26.6 million shares reserved under the 2012 Employee Plan, as well as up to 6.0 million shares forfeited under certain prior employee stock plans during the life of the 2012 Employee Plan. The 2012 Employee Plan permits the grant of stock options, restricted stock units, and restricted stock awards. Each restricted stock unit or restricted stock award granted will be counted against the shares authorized for issuance under the 2012 Employee Plan as 1.79 shares. If a granted option, restricted stock unit, or restricted stock award expires or becomes unexercisable for any reason, the unpurchased or forfeited shares that were granted may be returned to the 2012 Employee Plan and may become available for future grant under the 2012 Employee Plan. As of January 31, 2015, 22.1 million shares subject to options or restricted stock awards have been granted under the 2012 Employee Plan. Options and restricted stock that were granted under the 2012 plan vest over periods ranging from immediately upon grant to over a three year period and options expire 10 years from the date of grant. The 2012 Employee Plan will expire on June 30, 2022. At January 31, 2015, 12.3 million shares were available for future issuance under the 2012 Employee Plan.

The 2012 Director's Plan was approved by Autodesk's stockholders and became effective on January 6, 2012. The 2012 Directors' Plan replaced the 2010 Outside Directors' Stock Plan, as amended ("2010 Plan"). The 2012 Directors' Plan permits the grant of stock options, restricted stock units, and restricted stock awards to non-employee members of Autodesk’s Board of Directors. Each restricted stock unit or restricted stock award granted will be counted against the shares authorized for issuance under the 2012 Directors' Plan as 2.11 shares. As of January 31, 2015, 0.6 million shares subject to restricted stock unit awards have been granted under the 2012 Directors' Plan. Restricted stock units that were granted under the 2012 Outside Directors' Plan vest over one to three years from the date of grant. The 2012 Directors' Plan reserved 2.6 million shares of Autodesk common stock. The 2012 Directors' Plan will expire on June 30, 2022. At January 31, 2015, 2.0 million shares were available for future issuance under the 2012 Director's Plan.

The following sections summarize activity under Autodesk’s stock plans.

(1) Autodesk did not grant stock options in the twelve months ended January 31, 2015.

(2) Options expected to vest reflect an estimated forfeiture rate.

(3) Represents the total pre-tax intrinsic value, based on Autodesk’s closing stock price of $54.01 per share as of January 31, 2015, which would have been received by the option holders had all option holders exercised their options as of that date.

As of January 31, 2015, compensation cost of $0.6 million related to non-vested options is expected to be recognized over a weighted average period of 0.2 years.

The following table summarizes information about the pre-tax intrinsic value of options exercised and the weighted average grant date fair value per share of options granted during the fiscal years ended January 31, 2015, 2014, and 2013:

	Fiscal year ended January 31,
	2015		2014		2013

Weighted average grant date fair value per share of stock options granted (2)	$	—	$	—	$	13.4

——————

(1) The intrinsic value of options exercised is calculated as the difference between the exercise price of the option and the market value of the stock on the date of exercise.

(2) The weighted average grant date fair value per share of stock options granted is calculated, as of the stock option grant date, using the Black-Scholes Merton ("BSM") option pricing model. For the twelve months ended January 31, 2015 and 2014, Autodesk did not grant stock options.

The following table summarizes information about options vested and exercisable, and outstanding at January 31, 2015:

These options will expire if not exercised at specific dates ranging through September 2022.

Restricted Stock:

A summary of restricted stock unit activity for the fiscal year ended January 31, 2015 is as follows:

	Unreleased Restricted Stock Units		Weighted average grant date fair value
	(in thousands)
Unreleased restricted stock units at January 31, 2014	6,515.6		$	39.15
Granted	4,481.8		54.17
Vested	(2,675.6	)	37.36
Canceled/Forfeited	(445.8	)	41.43
Performance Adjustment (1)	(74.7	)	42.23
Unreleased restricted stock units at January 31, 2015	7,801.3		$	48.46

_______________

(1) Based on Autodesk's financial results for the performance period, the fiscal 2014 and 2013 performance stock units were earned at 65.8% and 92.3% of the target award, respectively. The vesting of the performance stock units is subject to the holders satisfying the remaining service condition of the awards.

For the restricted stock units granted during fiscal years ended January 31, 2015, 2014, and 2013, the weighted average grant date fair value was $54.17, $42.37, and $33.32, respectively. The grant date fair value of the shares vested during fiscal years ended January 31, 2015, 2014, and 2013 was $100.0 million, $73.8 million, and $33.6 million, respectively.

During the fiscal year ended January 31, 2015, Autodesk granted 4.0 million restricted stock units. The restricted stock units vest over periods ranging from immediately upon grant to a pre-determined date that is typically within three years from the date of grant. Restricted stock units are not considered outstanding stock at the time of grant, as the holders of these units are not entitled to any of the rights of a stockholder, including voting rights. The fair value of the restricted stock units is expensed ratably over the vesting period. Autodesk recorded stock-based compensation expense related to restricted stock units of $118.9 million, $74.9 million, and $70.5 million during fiscal years ended January 31, 2015, 2014, and 2013, respectively. Included in the $70.5 million incurred in fiscal 2013, Autodesk incurred $16.6 million relating to the acceleration of vesting of equity awards held in Socialcam for Socialcam employees immediately prior to the acquisition. As of January 31, 2015, total compensation cost not yet recognized of $245.0 million related to non-vested awards, is expected to be recognized over a weighted average period of 1.8 years. At January 31, 2015, the number of restricted stock units granted but unvested was 6.9 million.

During the fiscal year ended January 31, 2015, Autodesk granted 0.5 million performance stock units ("PSUs") for which the ultimate number of shares earned is determined based on the achievement of performance criteria at the end of the stated performance period. The performance criteria are based upon billings and subscriptions goals adopted by the Compensation and Human Resource Committee (the “Annual Financial Results”), as well as total stockholder return compared against the S&P Computer Software Select Index (“Relative TSR”). Each PSU covers a three year period:

• Up to one third of the PSU may vest following year one depending upon the achievement of Annual Financial Results for year one as well as 1 year Relative TSR (covering year one).

• Up to one third of the PSU may vest following year two depending upon the achievement of Annual Financial Results for year two as well as 2 year Relative TSR (covering years one and two).

• Up to one third of the PSU may vest following year three depending upon the achievement of Annual Financial Results for year three as well as 3 year Relative TSR (covering years one, two, and three).

PSUs are not considered outstanding stock at the time of grant, as the holders of these units are not entitled to any of the rights of a stockholder, including voting rights. Autodesk has determined the grant-date fair value for these awards using a Monte Carlo simulation model since the awards are subject to a market condition. The fair value of the performance restricted stock units is expensed using the accelerated attribution method over the vesting period. Autodesk recorded stock-based compensation expense related to PSUs of $17.5 million, $8.7 million, and $8.1 million during fiscal year ended January 31, 2015, 2014, and 2013 respectively. As of January 31, 2015, total compensation cost not yet recognized of $2.5 million related to non-vested PSUs, is expected to be recognized over a weighted average period of 0.8 years. At January 31, 2015, the number of PSUs granted but unvested was 0.9 million.

1998 Employee Qualified Stock Purchase Plan (“ESP Plan”)

Under Autodesk’s ESP Plan, which was approved by stockholders in 1998, eligible employees may purchase shares of Autodesk’s common stock at their discretion using up to 15% of their eligible compensation subject to certain limitations, at not less than 85% of fair market value as defined in the ESP Plan. At January 31, 2015, a total of 40.7 million shares were available for future issuance. This amount automatically increases on the first trading day of each fiscal year by an amount equal to the lesser of 10.0 million shares or 2% of the total of (1) outstanding shares plus (2) any shares repurchased by Autodesk during the prior fiscal year. Under the ESP Plan, the Company issues shares on the first trading day following March 31 and September 30 of each fiscal year. The ESP Plan expires during fiscal 2018.

Autodesk issued 2.1 million shares under the ESP Plan at an average price of $33.91 per share in fiscal 2015, 2.9 million shares at an average price of $22.61 per share in fiscal 2014, and 2.9 million shares at an average price of $21.79 per share in fiscal 2013. The weighted average grant date fair value of awards granted under the ESP Plan during fiscal 2015, 2014, and 2013, calculated as of the award grant date using the BSM option pricing model, was $15.14, $11.80, and $12.21 per share, respectively. Autodesk recorded $23.9 million, $22.9 million, and $34.0 million of compensation expense associated with the ESP Plan in fiscal 2015, 2014, and 2013, respectively.

Borrowing Arrangements

Borrowing Arrangements

In December 2012, Autodesk issued $400.0 million aggregate principal amount of 1.95% senior notes due December 15, 2017 and $350.0 million aggregate principal amount of 3.6% senior notes due December 15, 2022, (collectively, the "Senior Notes"). Autodesk received net proceeds of $739.3 million from issuance of the Senior Notes, net of a discount of $4.5 million and issuance costs of $6.1 million. Both the discount and issuance costs are being amortized to interest expense over the respective terms of the Senior Notes using the effective interest method. The proceeds of the Senior Notes are available for general corporate purposes. Autodesk may redeem the Senior Notes at any time, subject to a make whole premium. In addition, upon the occurrence of certain change of control triggering events, Autodesk may be required to repurchase the Senior Notes, at a price equal to 101% of their principal amount, plus accrued and unpaid interest to the date of repurchase. The Senior Notes contain restrictive covenants that limit our ability to create certain liens, to enter into certain sale and leaseback transactions and to consolidate or merge with, or convey, transfer, or lease all or substantially all of our assets, subject to significant qualifications and exceptions. Based on quoted market prices, the fair value of the Senior Notes was approximately $759.9 million as of January 31, 2015.

Autodesk’s line of credit facility permits unsecured short-term borrowings of up to $400.0 million with an option to request an increase in the amount of the credit facility by up to an additional $100.0 million, and is available for working capital or other business needs. This credit agreement contains customary covenants that could restrict the imposition of liens on Autodesk’s assets, and restrict the Company’s ability to incur additional indebtedness or make dispositions of assets if Autodesk fails to maintain the financial covenants. The financial covenants consist of a leverage ratio, and an interest coverage ratio. The line of credit is syndicated with various financial institutions, including Citibank, N.A., an affiliate of Citigroup, which is one of the lead lenders and an agent. As of January 31, 2015, we were in compliance with the credit facility’s covenants.The credit facility expires in May 2018. At January 31, 2015 and January 31, 2014, Autodesk had no outstanding borrowings on this line of credit.

Business Combinations [Abstract]

Acquisitions

Acquisitions

During the fiscal years ended January 31, 2015 and January 31, 2014, Autodesk completed the business combinations and technology purchases described below. The results of operations for the following acquisitions are included in the accompanying Consolidated Statement of Operations since their respective acquisition dates. Pro forma results of operations have not been presented because the effects of the following acquisitions, individually and in the aggregate, were not material to Autodesk's Consolidated Financial Statements.

For acquisitions accounted for as business combinations, Autodesk recorded the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The fair values assigned to the identifiable intangible assets acquired were based on estimates and assumptions determined by management. Autodesk recorded the excess of consideration transferred over the aggregate fair values as goodwill.

Fiscal 2015 Acquisitions

On June 27, 2014, Autodesk acquired Shotgun Software, Inc. (“Shotgun”) for total consideration of $54.5 million, of which $51.2 million was cash consideration. Prior to acquiring Shotgun, Autodesk had a convertible debt investment in the company with an acquisition-date fair value of $3.3 million using a market approach to value the investment. Shotgun was a privately-owned company that provided a cloud-based production management solution that enabled digital studios to track, schedule, review, and collaborate on projects and images. Shotgun has been integrated into, and the related goodwill was assigned to, Autodesk's M&E segment. Goodwill is not expected to be deductible for U.S. income tax purposes.

On May 29, 2014, Autodesk acquired all the outstanding shares of Within Technologies Limited ("Within Technologies”) for total cash consideration of $88.0 million. Autodesk used its non-U.S.-based cash for the transaction. Within Technologies is a United Kingdom based developer of design and simulation software for next generation manufacturing processes.  The Within Technologies acquisition is expected to accelerate Autodesk’s development of tools and technologies for advanced manufacturing.  Within Technologies has been integrated into Autodesk’s PSEB reportable segment. The amount of goodwill that is expected to be deductible for U.S. income tax purposes is $78.9 million.

On February 6, 2014, Autodesk acquired the entire issued and to be issued share capital of Delcam plc (“Delcam”), for $284.6 million. Delcam was previously listed as a public company (LON: DLC) and is a leading supplier of advanced CADCAM and industrial measurement solutions for the manufacturing industry. With this transaction Autodesk gains Delcam’s range of design, manufacturing, and inspection software that provide automated CADCAM solutions for a variety of industries, ranging from aerospace to toys and sports equipment. The transaction was structured as a cash offer for all the outstanding shares of Delcam, and Delcam has been integrated into Autodesk's MFG reportable segment. The amount of goodwill that is expected to be deductible for U.S. income tax purposes is $166.0 million.

During the fiscal year ended January 31, 2015, Autodesk also completed 21 other business combination and technology acquisitions for total cash consideration of $234.5 million. These business combinations and technology acquisitions were not material individually or in aggregate to Autodesk's Consolidated Financial Statements.

The following table summarizes the fair value of the assets acquired and liabilities assumed by major class for each of the business combinations and technology acquisitions completed during the fiscal year ended January 31, 2015:

	Shotgun			Within			Delcam			Other
Developed technologies	$	5.4		$	4.6		$	28.9		$	39.0
Customer relationships and other non-current intangible assets	7.5			3.6			39.7			9.8
Trade name	1.6			1.2			16.5			6.3
Goodwill	43.2			80.6			190.4			180.6
Deferred Revenue (current and non-current)	(0.7		)	—			(10.4		)	(0.4		)
Deferred tax liability	(2.6		)	(1.7		)	(13.2		)	(2.1		)
Net tangible assets (liabilities)	0.1			(0.3		)	32.7			1.3
	$	54.5		$	88.0		$	284.6		$	234.5

For Shotgun and certain other business combinations, the allocation of purchase price consideration to certain assets and liabilities is not yet finalized. Autodesk's estimates and assumptions are subject to change within the measurement period (up to one year from the acquisition date).

Commitments and Contingencies

Commitments and Contingencies

Lease commitments

Autodesk leases office space and computer equipment under non-cancellable operating lease agreements that expire at various dates through 2088. The leases generally provide that Autodesk pay taxes, insurance, and maintenance expenses related to the leased assets. Certain of these lease arrangements contain escalation clauses whereby monthly rent increases over time. At January 31, 2015, the aggregate future minimum lease payments required were as follows:

2016	$	55.4
2017	47.3
2018	40.7
2019	29.1
2020	19.5
Thereafter	32.6
	224.6
Less: Sublease income	1.9
	$	222.7

Rent expense related to these operating leases recognized on a straight-line basis over the lease period, was as follows:

	Fiscal Year Ended January 31,
	2015		2014		2013
Rent expense	$	55.0	$	50.2	$	56.1

Purchase commitments

In the normal course of business, Autodesk enters into various purchase commitments for goods or services. Total non-cancellable purchase commitments as of January 31, 2015 were approximately $85.4 millionfor periods through fiscal 2020. These purchase commitments primarily result from contracts for the acquisition of IT infrastructure, marketing, and software development services.

Autodesk has certain royalty commitments associated with the shipment and licensing of certain products. Royalty expense is generally based on a dollar amount per unit shipped or a percentage of the underlying revenue. Royalty expense, which was recorded under cost of license and other revenue on Autodesk’s Consolidated Statements of Operations, was $17.9 million in fiscal 2015, $18.0 million in fiscal 2014, and $16.4 million in fiscal 2013.

Guarantees and Indemnifications

In the normal course of business, Autodesk provides indemnifications of varying scopes, including limited product warranties and indemnification of customers against claims of intellectual property infringement made by third parties arising from the use of its products or services. Autodesk accrues for known indemnification issues if a loss is probable and can be reasonably estimated. Historically, costs related to these indemnifications have not been significant, and because potential future costs are highly variable, Autodesk is unable to estimate the maximum potential impact of these indemnifications on its future results of operations.

In connection with the purchase, sale, or license of assets or businesses with third parties, Autodesk has entered into or assumed customary indemnification agreements related to the assets or businesses purchased, sold or licensed. Historically, costs related to these indemnifications have not been significant, and because potential future costs are highly variable, Autodesk is unable to estimate the maximum potential impact of these indemnifications on its future results of operations.

As permitted under Delaware law, Autodesk has agreements whereby it indemnifies its officers and directors for certain events or occurrences while the officer or director is, or was, serving at Autodesk’s request in such capacity. The maximum potential amount of future payments Autodesk could be required to make under these indemnification agreements is unlimited; however, Autodesk has directors’ and officers’ liability insurance coverage that is intended to reduce its financial exposure and may enable Autodesk to recover a portion of any future amounts paid. Autodesk believes the estimated fair value of these indemnification agreements in excess of applicable insurance coverage is minimal.

Legal Proceedings

Autodesk is involved in a variety of claims, suits, investigations, and proceedings in the normal course of business activities including claims of alleged infringement of intellectual property rights, commercial, employment, piracy prosecution, business practices, and other matters. In the Company's opinion, resolution of pending matters is not expected to have a material adverse impact on its consolidated results of operations, cash flows, or its financial position. Given the unpredictable nature of legal proceedings, there is a reasonable possibility that an unfavorable resolution of one or more such proceedings could in the future materially affect the Company's results of operations, cash flows, or financial position in a particular period, however, based on the information known by the Company as of the date of this filing and the rules and regulations applicable to the preparation of the Company's financial statements, any such amount is either immaterial or it is not possible to provide an estimated amount of any such potential loss.

Segment Reporting [Abstract]

Segments

Segments

Autodesk reports segment information based on the “management” approach. The management approach designates the internal reporting used by management for making decisions and assessing performance as the source of the Company’s reportable segments. Autodesk has four reportable segments: AEC, PSEB, MFG, and M&E. Autodesk has no material inter-segment revenue.

The AEC, PSEB, and MFG segments derive revenue from the sale of licenses for software products and services to customers who design, build, manage, or own building, manufacturing, and infrastructure projects. Autodesk's M&E segment derives revenue from the sale of products to creative professionals, post-production facilities, and broadcasters for a variety of applications, including feature films, television programs, commercials, music and corporate videos, interactive game production, web design, and interactive web streaming.

AEC software products help to improve the way building, civil infrastructure, process plant, and construction projects are designed, built, and managed. A broad portfolio of solutions enables greater efficiency, accuracy, and sustainability across the entire project lifecycle. Autodesk AEC solutions include advanced technology for BIM, AutoCAD-based design and documentation productivity software, sustainable design analysis applications, and collaborative project management solutions. BIM, an integrated process for building and infrastructure design, analysis, documentation, and construction, uses consistent, coordination information to improve communication and collaboration between the extended project team. AEC provides a comprehensive portfolio of BIM solutions that help customers deliver projects faster and more economically, while minimizing environmental impact. AEC’s revenue primarily includes revenue from the sales of licenses of Autodesk Building Design Suites, Autodesk Revit, Autodesk Infrastructure Design Suites, AutoCAD Civil 3D, and AutoCAD Map 3D.

PSEB includes Autodesk’s design product, AutoCAD. Autodesk’s AutoCAD product is a platform product that underpins the Company’s design product offerings for the industries it serves. For example, AEC and MFG offer tailored versions of AutoCAD software for the industries they serve. Autodesk’s AutoCAD product also provides a platform for Autodesk’s developer partners to build custom solutions for a range of diverse design-oriented markets. PSEB's revenue primarily includes revenue from sales of AutoCAD and AutoCAD LT, the AutoCAD Design Suite and many other design products, including consumer design products, as well as from sales of licenses of other Autodesk's design products.

MFG provides the manufacturers in automotive and transportation, industrial machinery, consumer products and building products with comprehensive digital prototyping solutions that bring together design data from all phases of the product development process to develop a single digital model created in Autodesk Inventor software. Autodesk’s solutions for digital prototyping enable a broad group of manufacturers to realize benefits with minimal disruption to existing workflows. MFG’s revenue primarily includes revenue from the sales of licenses of Autodesk Product Design Suites, Autodesk Inventor, AutoCAD Mechanical, and Autodesk Moldflow products.

M&E consists of two product groups: Animation, including design visualization, and Creative Finishing. Animation products, such as Autodesk 3ds Max, Autodesk Maya, and the Autodesk Entertainment Creation Suites, provide tools for digital sculpting, modeling, animation, effects, rendering and compositing, for design visualization, visual effects, and games production. M&E products are also included in a number of PSEB, AEC, and MFG focused suites. Creative Finishing products, such as Autodesk Flame, Autodesk Smoke, and Autodesk Lustre, provide editing, finishing, and visual effects design and color grading.

All of Autodesk’s reportable segments distribute their respective products primarily through authorized resellers and distributors and, to a lesser extent, through direct sales to end-users.

The accounting policies of the reportable segments are the same as those described in Note 1, “Business and Summary of Significant Accounting Policies.” Autodesk evaluates each segment’s performance on the basis of gross profit. Autodesk currently does not separately accumulate and report asset information by segment, except for goodwill, which is disclosed in Note 1, “Business and Summary of Significant Accounting Policies.”

Business and Summary of Significant Accounting Policies (Policies)

12 Months Ended

Jan. 31, 2015

Accounting Policies [Abstract]

Business

Business

Autodesk, Inc. (“Autodesk” or the “Company”) is a world leading design software and services company, offering customers productive business solutions through powerful technology products and services. The Company serves customers in the architecture, engineering, and construction; manufacturing; and digital media, consumer, and entertainment industries. The Company’s sophisticated software products enable its customers to experience their ideas before they are real by allowing them to imagine, design, and create their ideas and to visualize, simulate, and analyze real-world performance early in the design process by creating digital prototypes. These capabilities allow Autodesk’s customers to foster innovation, optimize and improve their designs, help save time and money, improve quality, and collaborate with others. Autodesk software products are sold globally, both directly to customers and through a network of resellers and distributors.

Principles of Consolidation

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of Autodesk and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.

Reclassifications

Reclassifications

During the first quarter of fiscal 2014, Autodesk combined maintenance revenue and cloud services offering-related revenue into one category named “Subscription.” As a result, revenue and cost of revenue related to cloud service offerings previously reflected in “License and other revenue” and “Cost of license and other revenue” were reclassified to “Subscription revenue” and “Cost of subscription revenue.”

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in Autodesk’s consolidated financial statements and notes thereto. These estimates are based on information available as of the date of the consolidated financial statements. On a regular basis, management evaluates these estimates and assumptions. Actual results may differ materially from these estimates.

Examples of significant estimates and assumptions made by management involve the determination of the fair value of acquired assets and liabilities, goodwill, financial instruments, long-lived assets and other intangible assets, the realizability of deferred tax assets, and the fair value of stock awards. The Company also makes assumptions, judgments, and estimates in determining the accruals for uncertain tax positions, variable compensation, partner incentive programs, product returns reserves, allowances for doubtful accounts, asset retirement obligations, and legal contingencies.

Foreign Currency Translation and Transactions

Foreign Currency Translation and Transactions

The assets and liabilities of Autodesk’s foreign subsidiaries are translated from their respective functional currencies into U.S. dollars at the rates in effect at the balance sheet date, and revenue and expense amounts are translated at exchange rates that approximate those rates in effect during the period in which the underlying transactions occur. Foreign currency translation adjustments are recorded as other comprehensive income (loss).

Gains and losses realized from foreign currency transactions, those transactions denominated in currencies other than the foreign subsidiary’s functional currency, are included in interest and other income, net. Monetary assets and liabilities are remeasured using foreign currency exchange rates at the end of the period, and non-monetary assets are remeasured based on historical exchange rates.

Derivative Financial Instruments

Derivative Financial Instruments

Under its risk management strategy, Autodesk uses derivative instruments to manage its short-term exposures to fluctuations in foreign currency exchange rates which exist as part of ongoing business operations. Autodesk’s general practice is to hedge a majority of transaction exposures denominated in euros, Japanese yen, Swiss francs, British pounds, Canadian dollars, and Australian dollars. These instruments have maturities between one to 12 months in the future. Autodesk does not enter into any derivative instruments for trading or speculative purposes.

The bank counterparties in all contracts expose Autodesk to credit-related losses in the event of their nonperformance. However, to mitigate that risk, Autodesk only contracts with counterparties who meet the Company’s minimum requirements under its counterparty risk assessment process. Autodesk monitors ratings, credit spreads, and potential downgrades on at least a quarterly basis. Based on Autodesk’s on-going assessment of counterparty risk, the Company will adjust its exposure to various counterparties. Autodesk generally enters into master netting arrangements, which reduce credit risk by permitting net settlement of transactions with the same counterparty. However, Autodesk does not have any master netting arrangements in place with collateral features.

Autodesk accounts for its derivative instruments as either assets or liabilities on the balance sheet and carries them at fair value. Gains and losses resulting from changes in fair value are accounted for depending on the use of the derivative and whether it is designated and qualifies for hedge accounting. Derivatives that do not qualify for hedge accounting are adjusted to fair value through earnings.

Cash and Cash Equivalents

Cash and Cash Equivalents

Autodesk considers all highly liquid investments with insignificant interest rate risk and remaining maturities of three months or less at the date of purchase to be cash equivalents. Cash equivalents are recorded at cost, which approximates fair value.

Marketable Securities

Marketable Securities

Marketable securities are stated at fair value. Marketable securities maturing within one year that are not restricted are classified as current assets.

Autodesk determines the appropriate classification of its marketable securities at the time of purchase and re-evaluates such classification as of each balance sheet date. Autodesk carries all “available-for-sale securities” at fair value, with unrealized gains and losses, net of tax, reported in stockholders’ equity until disposition or maturity. Autodesk carries all “trading securities” at fair value, with unrealized gains and losses, recorded in “Interest and other income, net” in the Company’s Consolidated Statements of Operations.

All of Autodesk’s marketable securities are subject to a periodic impairment review. The Company recognizes an impairment charge when a decline in the fair value of its investments below the cost basis is judged to be other-than-temporary. Autodesk considers various factors in determining whether to recognize an impairment charge, including the length of time and extent to which the fair value has been less than Autodesk’s cost basis, the financial condition and near-term prospects of the investee, and Autodesk’s intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery in the market value.

Accounts Receivable, Net

Allowances for uncollectible trade receivables are based upon historical loss patterns, the number of days that billings are past due, and an evaluation of the potential risk of loss associated with problem accounts.

The product returns reserves are based on historical experience of actual product returns, estimated channel inventory levels, the timing of new product introductions, channel sell-in for applicable markets, and other factors.

As part of the indirect channel model, Autodesk has a partner incentive program that uses quarterly attainment of monetary rewards to motivate distributors and resellers to achieve mutually agreed upon business goals in a specified time period. A portion of these incentives reduce license and other revenue in the current period. The remainder, which relates to incentives on our Subscription Program, is recorded as a reduction to deferred revenue in the period the maintenance transaction is billed and subsequently recognized as a reduction to maintenance revenue over the contract period. These incentive balances do not require significant assumptions or judgments. The reserves associated with the partner incentive program are treated on the consolidated balance sheet as either contra account receivable (when due to distributors and direct resellers) or accounts payable (when due to indirect resellers).

Concentration of Credit Risk

Concentration of Credit Risk

Autodesk places its cash, cash equivalents, and marketable securities in highly liquid instruments with, and in the custody of, diversified financial institutions globally with high credit ratings and limits the amounts invested with any one institution, type of security, and issuer.

Computer Equipment, Software, Furniture and Leasehold Improvements, Net

Computer Equipment, Software, Furniture, and Leasehold Improvements, Net

Computer equipment, software, and furniture are depreciated using the straight-line method over the estimated useful lives of the assets, which range from three to five years. Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated useful lives or the lease term.

Costs incurred for computer software developed or obtained for internal use are capitalized for application development activities, if material, and immediately expensed for preliminary project activities and post-implementation activities. These capitalized costs are amortized over the software’s expected useful life, which is generally three years.

Software Development Costs

Software Development Costs

Software development costs incurred prior to the establishment of technological feasibility are included in research and development expenses. Autodesk defines establishment of technological feasibility as the completion of a working model. Software development costs incurred subsequent to the establishment of technological feasibility through the period of general market availability of the products are capitalized and generally amortized over a three year period, if material.

Other Intangible Assets, Net

Other Intangible Assets, Net

Other intangible assets include developed technologies, customer relationships, trade names, patents, user lists, and the related accumulated amortization. These assets are shown as “Developed technologies, net” and as part of “Other assets” in the Consolidated Balance Sheet. The majority of Autodesk’s other intangible assets are amortized to expense over the estimated economic life of the product, which ranges from one to ten years.

Goodwill

Goodwill

Goodwill consists of the excess of the consideration transferred over the fair value of net assets acquired in business combinations. Autodesk assigns goodwill to the reporting unit associated with each business combination, and tests goodwill for impairment annually in its fourth fiscal quarter or more often if circumstances indicate a potential impairment. For purposes of the goodwill impairment test, a reporting unit is an operating segment or one level below.

Autodesk has the option to perform an assessment of qualitative factors of impairment (“optional assessment”) prior to necessitating a two-step quantitative impairment test. Should the optional assessment be utilized for any given fiscal year, qualitative factors to consider include cost factors; financial performance; legal, regulatory, contractual, political, business, or other factors; entity specific factors; industry and market considerations, macroeconomic conditions, and other relevant events and factors affecting the reporting unit. If, after assessing the totality of events or circumstances, it is more likely than not that the fair value of the reporting unit is greater than its carrying value, then performing the two-step impairment test is unnecessary.

Therefore, the two-step quantitative impairment test is necessary when either Autodesk does not utilize the optional assessment or, as a result of the optional assessment, it is not more likely than not that the fair value of the reporting unit is greater than its carrying value. In performing the two-step impairment test, Autodesk uses discounted cash flow models which include assumptions regarding projected cash flows. Variances in these assumptions could have a significant impact on Autodesk's conclusion as to whether goodwill is impaired, or the amount of any impairment charge. Impairment charges, if any, result from instances where the fair values of net assets associated with goodwill are less than their carrying values. As changes in business conditions and assumptions occur, Autodesk may be required to record impairment charges. The process of evaluating the potential impairment of goodwill is subjective and requires significant judgment at many points during the analysis. The value of Autodesk’s goodwill could also be impacted by future adverse changes such as: (i) declines in Autodesk’s actual financial results, (ii) a sustained decline in Autodesk’s market capitalization, (iii) significant slowdown in the worldwide economy or the industries Autodesk serves, or (iv) changes in Autodesk’s business strategy or internal financial forecast results.

For the fiscal 2015 annual goodwill impairment testing, Autodesk had five reporting units: PSEB, Manufacturing ("MFG"), Architecture, Engineering, and Construction ("AEC"), Media and Entertainment ("M&E"), and Delcam.

For the annual impairment assessment in fiscal 2015, Autodesk utilized the optional assessment for Delcam. Based on a review of the qualitative factors described above, we determined that for our Delcam reporting unit, it was more likely than not that the fair value of the reporting unit exceeded the carrying value. As a result, we concluded that performing the two-step impairment test was not necessary for Delcam.

For each of the remaining four reporting units, Autodesk did not utilize the optional assessment but rather performed the quantitative two-step impairment test. In performing the quantitative two-step test, Autodesk used a discounted cash flow model which included assumptions regarding projected cash flows.

Impairment of Long-Lived Assets

Impairment of Long-Lived Assets

At least annually or more frequently as circumstances dictate, Autodesk reviews its long-lived assets for impairment whenever impairment indicators exist.  Autodesk continually monitors events and changes in circumstances that could indicate the carrying amounts of its long-lived assets may not be recoverable. When such events or changes in circumstances occur, Autodesk assesses recoverability of these assets.  Recoverability is measured by comparison of the carrying amounts of the assets to the future undiscounted cash flows the assets are expected to generate.  If the long-lived assets are considered to be impaired, the impairment to be recognized is equal to the amount by which the carrying value of the assets exceeds its fair market value. Autodesk did not recognize any impairment of long-lived assets during the fiscal years ended January 31, 2015, 2014, and 2013, respectively.

In addition to the recoverability assessments, Autodesk routinely reviews the remaining estimated useful lives of its long-lived assets. Any reduction in the useful life assumption will result in increased depreciation and amortization expense in the quarter when such determinations are made, as well as in subsequent quarters.

Deferred Tax Assets

Deferred Tax Assets

Deferred tax assets arise primarily from tax credits, net operating losses, and timing differences for reserves, accrued liabilities, stock options, deferred revenue, purchased technologies, and capitalized intangibles, partially offset by the establishment of U.S. deferred tax liabilities on unremitted earnings from certain foreign subsidiaries, and valuation allowances against U.S. and foreign deferred tax assets. We perform a quarterly assessment of the recoverability of these net deferred tax assets and believe that we will generate sufficient future taxable income in appropriate tax jurisdictions to realize the net deferred tax assets. They are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to reverse. Valuation allowances are established when necessary to reduce gross deferred tax assets to the amount “more likely than not” expected to be realized.

Revenue Recognition

Revenue Recognition

Autodesk recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed or determinable, and collection is probable.

For multiple element arrangements containing only software and software-related elements, Autodesk allocates the sales price among each of the deliverables using the residual method, under which revenue is allocated to undelivered elements based on their vendor-specific objective evidence (“VSOE”) of fair value. VSOE is the price charged when an element is sold separately or a price set by management with the relevant authority. If Autodesk does not have VSOE of an undelivered element, revenue recognition is deferred on the entire sales arrangement until all elements for which Autodesk does not have VSOE are delivered. If Autodesk does not have VSOE for undelivered maintenance or services, the revenue for the arrangement is recognized over the longest contractual service period in the arrangement. Revenue recognition for significant lines of business is discussed further below.

For multiple element arrangements involving non-software elements, including cloud subscription services, our revenue recognition policy is based upon the accounting guidance contained in ASC 605, Revenue Recognition. For these arrangements, Autodesk first allocates the total arrangement consideration based on the relative selling prices of the software group of elements as a whole and the non-software elements. Autodesk then further allocates consideration within the software group to the respective elements within that group using the residual method as described above. Autodesk exercises judgment and uses estimates in connection with the determination of the amount of revenue to be recognized in each accounting period.

Autodesk allocates the total arrangement consideration among the various elements based on a selling price hierarchy. The selling price for a deliverable is based on its VSOE if available, third-party evidence ("TPE") if VSOE is not available, or the best estimated selling price ("BESP") if neither VSOE nor TPE is available. BESP represents the price at which Autodesk would transact for the deliverable if it were sold regularly on a standalone basis. To establish BESP for those elements for which neither VSOE nor TPE are available, Autodesk performs a quantitative analysis of pricing data points for historical standalone transactions involving such elements for a twelve-month period. As part of this analysis, Autodesk monitors and evaluates the BESP against actual pricing to ensure that it continues to represent a reasonable estimate of the standalone selling price, considering several other external and internal factors including, but not limited to, pricing and discounting practices, contractually stated prices, the geographies in which Autodesk offers products and services, and the type of customer (i.e. distributor, value-added reseller, and direct end user, among others). Autodesk analyzes BESP at least annually or on a more frequent basis if a significant change in our business necessitates a more timely analysis, or if significant selling price variances are experienced.

Autodesk’s assessment of likelihood of collection is also a critical element in determining the timing of revenue recognition. If collection is not probable, the revenue will be deferred until the earlier of when collection is deemed probable or cash is received.

License and other revenue are comprised of two components: (1) all forms of product license revenue and (2) other revenue.

(1) All Forms of Product License Revenue

Product license revenue includes: software license revenue from the sale of new seat licenses and upgrades and product revenue for Creative Finishing.

(2) Other Revenue

Other revenue includes revenue from consulting, training, Autodesk Developers Network, and Creative Finishing customer support, and is recognized over time, as the services are performed.

Autodesk's Subscription revenue consists of two components: maintenance revenue for our software products and revenue for our cloud service offerings, including Autodesk 360. Autodesk's maintenance program provides our commercial and educational customers of perpetual products with a cost effective and predictable budgetary option to obtain the productivity benefits of our new releases and enhancements when and if released during the term of their contracts. Under Autodesk's maintenance program, customers are eligible to receive unspecified upgrades when and if available, downloadable training courses, and online support. Autodesk recognizes maintenance revenue ratably over the term of the maintenance agreement, which is generally between one and three years but can occasionally be as long as five years. Revenue for Autodesk's cloud service offerings is recognized ratably over the contract term commencing with the date Autodesk's service is made available to customers and all other revenue recognition criteria have been satisfied.

Taxes Collected from Customers

Taxes Collected from Customers

Autodesk nets taxes collected from customers against those remitted to government authorities in the consolidated financial statements. Accordingly, taxes collected from customers are not reported as revenue.

Shipping and Handling Cost

Shipping and Handling Costs

Shipping and handling costs are included in cost of revenue for all periods presented.

Stock-Based Compensation Expense

Autodesk estimates expected volatility for stock-based awards based on the average of the following two measures. The first is a measure of historical volatility in the trading market for the Company’s common stock, and the second is the implied volatility of traded forward call options to purchase shares of the Company’s common stock. The expected volatility for PSUs subject to market conditions includes the expected volatility of Autodesk's peer companies within the S&P Computer Software Select Index.

Autodesk estimates the expected life of stock-based awards using both exercise behavior and post-vesting termination behavior as well as consideration of outstanding options.

Autodesk did not pay cash dividends in fiscal 2015, 2014, or 2013 and does not anticipate paying any cash dividends in the foreseeable future. Consequently, an expected dividend yield of zero is used in the Black-Scholes-Merton option pricing model and the Monte Carlo simulation model.

The risk-free interest rate used in the BSM option pricing model and the Monte Carlo simulation model for stock-based awards is the historical yield on U.S. Treasury securities with equivalent remaining lives.

Autodesk recognizes expense only for the stock-based awards that are ultimately expected to vest. Therefore, Autodesk has developed an estimate of the number of awards expected to cancel prior to vesting (“forfeiture rate”). The forfeiture rate is estimated based on historical pre-vest cancellation experience and is applied to all stock-based awards. The Company estimates forfeitures at the time of grant and revises those estimates in subsequent periods if actual forfeitures differ from those estimates.

Autodesk determines the grant-date fair value of its share-based payment awards using a Black-Scholes Merton Option ("BSM") pricing model or the quoted stock price on the date of grant, unless the awards are subject to market conditions, in which case Autodesk uses a binomial-lattice model (e.g., Monte Carlo simulation model). The Monte Carlo simulation model utilizes multiple input variables to estimate the probability that market conditions will be achieved.

Advertising Expenses

Advertising Expenses

Advertising costs are expensed as incurred.

Net Income Per Share

Net Income Per Share

Basic net income per share is computed based on the weighted average number of shares of common stock outstanding for the period, excluding stock options and restricted stock units. Diluted net income per share is computed based upon the weighted average shares of common shares outstanding for the period and potentially dilutive common shares, including the effect of stock options and restricted stock units under the treasury stock method.

Defined Benefit Pension Plans

Defined Benefit Pension Plans

The funded status of Autodesk's defined benefit pension plans is recognized in the Consolidated Balance Sheets. The funded status is measured as the difference between the fair value of plan assets and the projected benefit obligation for the fiscal years presented. The projected benefit obligation represents the actuarial present value of benefits expected to be paid upon retirement based on employee services already rendered and estimated future compensation levels. The fair value of plan assets represents the current market value of Autodesk's cumulative company and participant contributions made to the various plans in effect.

Net periodic benefit cost is recorded in the Consolidated Statements of Operations and includes service cost, interest cost, expected return on plan assets, amortization of prior service costs, and gains or losses previously recognized as a component of other comprehensive income. Certain events, such as changes in the employee base, plan amendments, and changes in actuarial assumptions may result in a change in the defined benefit obligation and the corresponding change to other comprehensive income.

Gains and losses and prior service costs not recognized as a component of net periodic benefit cost in the Consolidated Statements of Operations as they arise are recognized as a component of other comprehensive income in the Consolidated Statements of Comprehensive Income. Those gains and losses and prior service costs are subsequently amortized as a component of net periodic benefit cost over the average remaining service lives of the plan participants using a corridor approach to determine the portion of gain or loss subject to amortization.

The measurement of projected benefit obligations and net periodic benefit cost is based on estimates and assumptions that reflect the terms of the plans and use participant-specific information such as compensation, age and years of services, as well as certain assumptions, including estimates of discount rates, expected return of plan assets, rate of compensation increases, interest rates, and mortality rates.

Accounting Standards in Fiscal 2015

Accounting Standards in Fiscal 2015

With the exception of those discussed below, there have been no recent changes in accounting pronouncements issued by the FASB or adopted by the Company during the fiscal year ended January 31, 2015, that are of significance, or potential significance, to the Company.

Accounting Standards Adopted

Effective February 1, 2014, Autodesk prospectively adopted FASB's Accounting Standards Update (“ASU”) 2013-11 regarding ASC Topic 740 “Income Tax.” This ASU clarifies the guidance on the presentation of an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the consolidated financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. The adoption of this ASU resulted in an $81.9M reduction of both our long term taxes payable and long-term deferred tax assets as of January 31, 2015.

Recently Issued Accounting Standards

On May 28, 2014, the FASB issued ASU 2014-09 regarding ASC Topic 606 “Revenue from Contracts with Customers.” This ASU provides principles for recognizing revenue for the transfer of promised goods or services to customers with the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU will be effective for Autodesk’s fiscal year beginning February 1, 2017. Early adoption is not permitted. Autodesk is currently evaluating the accounting, transition, and disclosure requirements of the standard and cannot currently estimate the financial statement impact of adoption.

(1) Included in “Cash and cash equivalents” in the accompanying Consolidated Balance Sheets.

(2) Consists of agency discount notes, U.S. treasury bills, and other short-term securities.

(3) Considered "available for sale" securities and included in "Other assets" in the accompanying Consolidated Balance Sheets.

(4) Included in “Prepaid expenses and other current assets,” "Other assets," or “Other accrued liabilities” in the accompanying Consolidated Balance Sheets.

Autodesk classifies its marketable securities as either short-term or long-term based on each instrument’s underlying contractual maturity date. Marketable securities with remaining maturities of less than 12 months are classified as short-term and marketable securities with remaining maturities greater than 12 months are classified as long-term. Autodesk may sell certain of its marketable securities prior to their stated maturities for strategic purposes or in anticipation of credit deterioration.

Autodesk applies fair value accounting for certain financial assets and liabilities, which consist of cash equivalents, marketable securities, and other financial instruments, on a recurring basis. The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement: (Level 1) observable inputs such as quoted prices in active markets; (Level 2) inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and (Level 3) unobservable inputs for which there is little or no market data, which require Autodesk to develop its own assumptions. When determining fair value, Autodesk uses observable market data and relies on unobservable inputs only when observable market data is not available. There have been no transfers between fair value measurement levels during the year ended January 31, 2015.

Autodesk's cash equivalents, marketable securities, and financial instruments are primarily classified within Level 1 or Level 2 of the fair value hierarchy. Autodesk values it's available for sale securities on pricing from pricing vendors, who may use quoted prices in active markets for identical assets (Level 1) or inputs other than quoted prices that are observable either directly or indirectly in determining fair value (Level 2). Autodesk's Level 2 securities are valued primarily using observable inputs other than quoted prices in active markets for identical assets and liabilities. Autodesk's Level 3 securities consist of investments held in auction rate securities, convertible debt securities, and derivative contracts which are valued using probability weighted discounted cash flow models and some of the inputs to the models are unobservable in the market.

A reconciliation of the change in Autodesk’s Level 3 items for the fiscal years ended January 31, 2015 and 2014 was as follows:

	Fair Value Measurements Using Significant Unobservable Inputs
	(Level 3)
		Derivative Contracts			Convertible Debt Securities			Taxable Auction-Rate Securities			Total
Balance at January 31, 2013		$	10.7		$	17.5		$	4.2		$	32.4

Losses included in earnings (1)		(2.9		)	—			(0.2		)	(3.1		)
Losses included in OCI (1)		—			(0.4		)	—			(0.4		)
Balance at January 31, 2014		9.1			20.2			—			29.3

Balance at January 31, 2015		$	0.9		$	5.1		$	—		$	6.0

(1) For comparability, the presentation of prior period balances were adjusted to align with current year presentation.

The following table summarizes the estimated fair value of Autodesk's “available-for-sale securities” classified by the contractual maturity date of the security:

	January 31, 2015
	Cost		Fair Value
Due in 1 year	$	575.4	$	575.5
Due in 1 year through 5 years	276.9		278.1
Total	$	852.3	$	853.6

As of January 31, 2015 and 2014, Autodesk did not have any securities in a continuous unrealized loss position for greater than twelve months.

As of January 31, 2015 and 2014 Autodesk had $52.6 million and $49.8 million, respectively, in direct investments of privately held companies accounted for under the cost method, which are periodically assessed for other-than-temporary impairment. If Autodesk determines that an other-than-temporary impairment has occurred, Autodesk writes down the investment to its fair value. Autodesk estimates fair value of its cost method investments considering available information such as pricing in recent rounds of financing, current cash positions, earnings and cash flow forecasts, recent operational performance, and any other readily available market data. During fiscal 2015, Autodesk recorded $19.2 million in other-than-temporary impairments on its privately held equity investments. During fiscal 2014, Autodesk recorded no other-than-temporary impairment on its privately held equity investments. The impairment expense was recorded in “Interest and other (expense) income, net” on the Company's Consolidated Statement of Operations.

The sales or settlement of “available-for-sale securities” in fiscal 2015 and fiscal 2014 resulted in a gain of $0.7 million and a loss of $0.2 million, respectively. The sales or redemptions of “available-for-sale securities” in fiscal 2013 resulted in no gains or losses. The losses and gains were recorded in "Interest and other (expense) income, net" on the Company's Consolidated Statement of Operations.

Proceeds from the sale and maturity of marketable securities for fiscal 2015 and fiscal 2014 were $1,159.0 million and $1,279.1 million, respectively.

Derivative Financial Instruments

Under its risk management strategy, Autodesk uses derivative instruments to manage its short-term exposures to fluctuations in foreign currency exchange rates that exist as part of ongoing business operations. Autodesk's general practice is to hedge a portion of transaction exposures denominated in euros, Japanese yen, Swiss francs, British pounds, Canadian dollars and Australian dollars. These instruments have maturities between one to twelve months in the future. Autodesk does not enter into derivative instrument transactions for trading or speculative purposes.

The bank counterparties to the derivative contracts potentially expose Autodesk to credit-related losses in the event of their nonperformance. However, to mitigate that risk, Autodesk only contracts with counterparties who meet the Company's minimum requirements under its counterparty risk assessment process. Autodesk monitors ratings, credit spreads, and potential downgrades on at least a quarterly basis. Based on Autodesk's on-going assessment of counterparty risk, the Company will adjust its exposure to various counterparties. Autodesk generally enters into master netting arrangements, which reduce credit risk by permitting net settlement of transactions with the same counterparty.  However, Autodesk does not have any master netting arrangements in place with collateral features.

Foreign currency contracts designated as cash flow hedges

Autodesk uses foreign currency contracts to reduce the exchange rate impact on a portion of the net revenue or operating expense of certain anticipated transactions. These contracts are designated and documented as cash flow hedges. The effectiveness of the cash flow hedge contracts is assessed quarterly using regression analysis as well as other timing and probability criteria. To receive cash flow hedge accounting treatment, all hedging relationships are formally documented at the inception of the hedge and the hedges are expected to be highly effective in offsetting changes to future cash flows on hedged transactions. The gross gains and losses on these hedges are included in “Accumulated other comprehensive loss” and are reclassified into earnings at the time the forecasted revenue or expense is recognized. In the event the underlying forecasted transaction does not occur, or it becomes probable that it will not occur, Autodesk reclassifies the gain or loss on the related cash flow hedge from “Accumulated other comprehensive loss” to “Interest and other (expense) income, net” in the Company's Consolidated Financial Statements at that time.

The net notional amount of these contracts are presented net settled and were $336.6 million at January 31, 2015 and $351.7 million at January 31, 2014. Outstanding contracts are recognized as either assets or liabilities on the Consolidated Balance Sheet at fair value. The majority of the net gain of $42.8 million remaining in “Accumulated other comprehensive loss” as of January 31, 2015 is expected to be recognized into earnings within the next twelve months.

Derivatives not designated as hedging instruments

Autodesk uses foreign currency contracts which are not designated as hedging instruments to reduce the exchange rate risk associated primarily with foreign currency denominated receivables and payables. These forward contracts are marked-to-market at the end of each fiscal quarter with gains and losses recognized as “Interest and other (expense) income, net.” These derivative instruments do not subject the Company to material balance sheet risk due to exchange rate movements because gains and losses on these derivative instruments are intended to offset the gains or losses resulting from the settlement of the underlying foreign currency denominated receivables and payables. The net notional amounts of these foreign currency contracts are presented net settled and were $44.6 million at January 31, 2015 and $205.5 million at January 31, 2014.

From time to time and consistent with its risk management policy, Autodesk also uses derivative instruments to hedge its economic exposure related to committed, in-process acquisitions priced in foreign currency.  Such derivatives do not qualify for hedge accounting and are marked-to-market through earnings, with any gain or loss reflected immediately in “Interest and other (expense) income, net,” in each period. 

In addition to these foreign currency contracts, Autodesk holds derivative instruments issued by privately held companies, which are not designated as hedging instruments. These derivatives consist of certain conversion options on the convertible debt securities held by Autodesk and an option to acquire a privately held company. These derivatives are recorded at fair value as of each balance sheet date and are recorded in “Other assets.” Changes in the fair values of these instruments are recognized in income as “Interest and other (expense) income, net.”

Fair Value of Derivative Instruments:

The fair value of derivative instruments in Autodesk’s Consolidated Balance Sheets were as follows as of January 31, 2015 and January 31, 2014:

	Balance Sheet Location	Fair Value at

Net Income Per Share

Jan. 31, 2015

Earnings Per Share [Abstract]

Net Income Per Share

Net Income Per Share

Basic net income per share is computed using the weighted average number of shares of common stock outstanding for the period, excluding stock options and restricted stock units. Diluted net income per share is based upon the weighted average number of shares of common stock outstanding for the period and potentially dilutive common shares, including the effect of stock options and restricted stock units under the treasury stock method. The following table sets forth the computation of the numerators and denominators used in the basic and diluted net income per share amounts:

	Fiscal Year Ended January 31,
	2015		2014		2013
Numerator:
Net income	$	81.8	$	228.8	$	247.4
Denominator:
Denominator for basic net income per share—weighted average shares	227.1		224.0		226.4
Effect of dilutive securities	5.3		5.6		5.3
Denominator for dilutive net income per share	232.4		229.6		231.7
Basic net income per share	$	0.36	$	1.02	$	1.09
Diluted net income per share	$	0.35	$	1.00	$	1.07

The computation of diluted net income per share does not include shares that are anti-dilutive under the treasury stock method because their exercise prices are higher than the average market value of Autodesk’s stock during the fiscal year. For the fiscal years ended January 31, 2015, 2014, and 2013, 0.1 million, 5.4 million, and 9.6 million potentially anti-dilutive shares, respectively, were excluded from the computation of net income per share.
