PART I

Item1. Business

Overview

Extreme Networks, Inc., together with its subsidiaries, (collectively referred to as Extreme and as we , us and our ) is a leading provider of network infrastructure equipment and services for enterprises, data centers, and service providers. Our customers include businesses, hospitals, hotels, universities, telecommunications companies and government agencies around the world. Since our founding in 1996, our vision has been a world enabled by a unified network based upon Ethernet that we believe simplifies each element and component of the network, and through simplification, provides services at a lower cost. As networks internal to businesses, between businesses and the Internet itself become more pervasive and critical to a wide variety of business and social communications, the volume and the demands of applications, data, users and devices on networks continue to increase. Our vision focuses on the design and delivery of easily deployable, highly scalable, secure and comprehensively managed networks which are reliable, fast, flexible and cost-effective. We primarily sell our products through an ecosystem of our channel partners who combine our Ethernet products with their offerings to create compelling information technology solutions for end user customers.

Industry Background

The networking industry has undergone significant changes in the last few years. With the mobilization of the workforce, the virtualization of the data center, and the demand for anywhere, anytime connectivity, across any device, Ethernet is the common technology across both enterprises and service providers. Extreme Networks' strategy, product portfolio, and research and development are aligned with the following trends:

growing interest in Software Defined Network ("SDN") approaches that may include technologies such as OpenFlow, OpenStack, and CloudStack.

The Extreme Networks Strategy

With the proliferation of mobile users and their devices, within a campus or across continents, the challenges of operating and managing a network have changed in the BYOD world of today. IT has rapidly evolved from a world of fixed to a new world of mobility where everything - people, devices, machines, and applications - are in motion. IT now has to support end-users with smart phones, tablets, laptops and other wireless peripherals as well as their wired workstations. Users are beginning to define the services that IT must offer as they adopt (smart phones and) tablets and their applications, and work on the go. Users know what they need to be productive, and they expect the network to help them achieve productivity.

Extreme Networks Open Fabric architecture delivers mission critical networks designed for this new BYOD world, spanning high-performance data centers, the campus, and the mobile infrastructure. Customers deploying our technology can know what resources are using the network, what they are requesting and where they are located, and can provide customized access to approved resources and content. Our networks help enable granular visibility and control, higher performance and resource security.

Extreme Networks strategy is to offer sophisticated, open, and cost effective scalable networks, an alternative to single-sourced, highly proprietary networking equipment from other companies. Our commitment to open standards is manifested by demonstrated interoperability within both enterprise and service provider networks, and the active participation in key industry and standards associations.

Key elements of our strategy include:

to support our channel partners and to sell directly to certain strategic accounts. As an independent Ethernet switch vendor, we seek to provide products that, when combined with the offerings of our channel partners, create compelling solutions for end-user customers.

Products

Our products offer a resilient, intelligent and sustainable foundation for IT.  We build our products into vertical markets solutions for converged campus networks with user and device mobility, and for Data Center and Cloud administrators to virtualize their server and storage over a high-performance Ethernet infrastructure, and Service Providers to provide bandwidth and Service Level Agreements for Carrier Ethernet, 3G and 4G services.

("PoE") solutions have been deployed within the customers' network, features within the Extreme XOS operating system can intelligently control the delivery of power to the attached devices. In addition to lower power consumption, the air flow on our Data Center switches is built to integrate well with hot-aisle-cool-aisle designs to help minimize cooling costs.

Our product categories include:

Sales, Marketing and Distribution

We conduct our sales and marketing activities on a worldwide basis through a distribution channel utilizing distributors, resellers and our field sales organization. We primarily sell our products through an ecosystem of channel partners who combine our Ethernet products with their offerings to create compelling information technology solutions for end-user customers. We utilize our field sales organization to support our channel partners and to sell direct to end-user customers, including some large global accounts.

Strategic Relationships. We have active strategic relationships with Barco NV, EMC, Ericsson Enterprise AB, Lenovo, PC HK Ltd., Motorola Inc., Nokia Siemens Networks and others where our products are qualified as part of an overall solution they market or they sell our products as part of an overall solution.

Distributors . We have established several key relationships with leading distributors in the electronics and computer networking industries. Each of our distributors primarily resells our products to resellers. The distributors enhance our ability to sell and provide support to resellers, who may benefit from the broad service and product fulfillment capabilities offered by these distributors. One distributor, Westcon Group, Inc., accounted for 16%, 19%, and 16% of our net revenue in fiscal years 2013 , 2012 and 2011 , respectively. Distributors are generally given the right to return a portion of inventory to us for the purpose of stock rotation, to claim rebates for competitive discounts and participate in various cooperative marketing programs to promote the sale of our products and services. We defer recognition of revenue on all sales to distributors who maintain inventory of our products until the distributors sell the product, as evidenced by monthly "sales-out" reports that the distributors provide to us, provided other revenue recognition criteria are met. (See "Revenue Recognition" in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations .)

Resellers. We rely on many resellers worldwide that sell directly to end-user customer. Our resellers include regional networking system resellers, resellers who focus on specific vertical markets, value added resellers, network integrators and wholesale resellers. We provide training and support to our resellers and our resellers generally provide the first level of contact to end-users of our products. Our relationships with resellers are on a non-exclusive basis. Our resellers are not given rights to return inventory and do not automatically participate in any cooperative marketing programs. We generally recognize product revenue from our reseller and end-user customers at the time of shipment, provided other revenue recognition criteria are met. When significant obligations or contingencies remain after products are delivered, such as installation or customer acceptance, revenue and related costs are deferred until such obligations or contingencies are satisfied. (See "Revenue Recognition" in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations .)

Field Sales. We have trained our field sales organization to support and develop leads for our resellers and to establish and maintain key accounts and strategic end-user customers. To support these objectives, our field sales force:

As of June 30, 2013 , our worldwide sales and marketing organization consisted of 262 employees, including vice presidents, directors, managers, sales representatives, and technical and administrative support personnel. We have domestic sales offices located in 5 states and international sales offices located in 25 countries.

Customers with 10% of net revenue or greater

The following table sets forth major customers accounting for 10% or more of our net revenue:

International sales

International sales are an important portion of our business. In fiscal 2013 , sales to customers outside of the United States accounted for 66% of our consolidated net revenue, compared to 67% in fiscal 2012 and 68% in fiscal 2011 . These sales are conducted primarily through foreign-based distributors and resellers managed by our worldwide sales organization. In addition, we have direct sales to end-user customers, including large global accounts. The primary markets for sales outside of the United States are countries in Europe and Asia, as well as Canada, Mexico, Central America and South America. (See "Net Revenue" in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations .)

Marketing

We continue to develop and execute on a number of marketing programs to support the sale and distribution of our products by communicating the value of our solutions to our existing and potential customers, our distribution channels and our resellers. Our marketing efforts include participation in industry tradeshows, conferences and seminars, publication of technical and educational articles in industry journals, frequent updates to our publicly available website, promotions, web-based training courses, advertising and public relations. We also submit our products for independent product testing and evaluation.

Backlog

Our products are often sold on the basis of standard purchase orders that are cancelable prior to shipment without significant penalties. In addition, purchase orders are subject to changes in quantities of products and delivery schedules in order to reflect changes in customer requirements and manufacturing capacity. Our business is characterized by seasonal variability in demand and short lead-time orders and delivery schedules. Actual shipments depend on the then-current capacity of our contract manufacturers and the availability of materials and components from our vendors. Although we believe that the orders included in the backlog are firm, all orders are subject to possible rescheduling by customers, cancellations by customers which we may elect to allow without penalty to customer, and further pricing adjustments on orders from distributors. Therefore, we do not believe that our backlog, as of any particular date is necessarily indicative of actual revenue for any future period.

Our product backlog at June 30, 2013 , the last day of our 2013 fiscal year, net of anticipated back end rebates for distributor sales, was approximately $16.4 million, compared with product backlog of approximately $10.6 million at June 30, 2012 , the last day of our 2012 fiscal year.

Seasonality

Like many of our competitors, we historically have experienced seasonal fluctuations in customer spending patterns, which generally adversely affect our first and third fiscal quarters. This pattern should not be relied upon or be considered indicative of our future performance, however, as it has varied in the past.

Customer Service and Support

Our customers seek high reliability and maximum uptime for their networks. To that extent, we provide the following service offerings:

Long-Lived Assets

See Note 2 of our Notes to Consolidated Financial Statements in this Annual Report on Form 10-K for more information regarding our long-lived assets.

Manufacturing

We outsource the majority of our manufacturing and supply chain management operations as part of our strategy to maintain global manufacturing capabilities and to reduce our costs. We conduct quality assurance, manufacturing engineering, document control and test development at engineering facilities in San Jose, California, RTP, North Carolina and Chennai, India. This approach enables us to reduce fixed costs and to flexibly respond to changes in market demand. Our end-to-end supply chain, including our three engineering facilities at San Jose, RTP and Chennai are all ISO 9001 certified.

We use Alpha Networks, Inc. headquartered in Hsinchu, Taiwan to design and build some of our products. Alpha Networks is a global networking Original Design Manufacturer ("ODM") leader with core competencies in areas such as Ethernet, LAN/MAN, Wireless, Broadband and VoIP. Alpha Networks, Inc.'s manufacturing processes and procedures are ISO 9001 certified.

Our wireless products are supplied under an Original Equipment Manufacturer ("OEM") supply agreement with Symbol Technologies, Inc., a subsidiary of Motorola, Inc. ("Motorola"). Motorola rebrands and customizes the wireless products for us to resell to customers. Motorola's manufacturing processes and procedures are ISO 9001 certified. Motorola has made ongoing supply and support commitments during the term of the agreement and is required to provide support for a defined period of time after any termination of the agreement.

These manufacturers utilize automated testing equipment to perform product testing and burn-in with specified tests. Together we rely upon comprehensive inspection testing and statistical process controls to assure the quality and reliability of our products.

We use our forecast of expected demand to determine our material requirements. Lead times for materials and components vary significantly, and depend on factors such as the specific supplier, contract terms and demand for a component at a given time. We order most of our materials and components on an indirect basis through our contract manufacturer. Purchase commitments with our manufacturers/ODM/OEM's are generally on a purchase order basis.

Research and Development

The success of our products to date is due in large part to our focus on research and development. We believe that continued success in the marketplace will depend on our ability to develop new and enhanced products employing leading-edge technology. Accordingly, we are undertaking development efforts with an emphasis on increasing the reliability, performance and features of our family of products, and designing innovative products to reduce the overall network operating costs of customers.

Our product development activities focus on solving the needs of enterprises, data centers, and service providers. Current activities include the continuing development of our innovative switching technology aimed at extending the capabilities of our products. Our ongoing research activities cover a broad range of areas, including, in particular, 40G and 100G Ethernet, routing, timing and resiliency protocols, open standards interfaces, software defined networks, network security, identity management, data center fabrics, and wireless networking.

We continue to enhance the functionality of our ExtremeXOS modular operating system which has been designed to provide high reliability and availability. This allows us to leverage a common operating system across different hardware and network chipsets.

As of June 30, 2013 , our research and development organization consisted of 191 employees. Research and development efforts are conducted in several locations, including San Jose, California; Raleigh, North Carolina; and Chennai, India. Our research and development expenses in fiscal years 2013 , 2012 and 2011 were $40.5 million , $45.6 million and $49.3 million , respectively.

Intellectual Property

We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. As of June 30, 2013 , we have 146 issued patents in the United States and 71 patents outside of the United States. The expiration dates of our issued patents in the United States range from 2017 to a pproximately 2030. Although we have patent applications pending, there can be no assurance that patents will be issued from pending applications or that claims allowed on any future patents will be sufficiently broad to protect our technology. With respect to trademarks, we have a number of pending and registered trademarks in the United States and abroad.

We enter into confidentiality or license agreements with our employees, consultants and corporate partners, and control access to, and distribution of, our software, documentation and other proprietary information. In addition, we provide our software

products to end-user customers primarily under "shrink-wrap" license agreements. These agreements are not negotiated with or signed by the licensee, and thus these agreements may not be enforceable in some jurisdictions. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy or otherwise obtain and use our products or technology, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States.

Competition

The market for network switches, which is part of the broader market for networking equipment, is extremely competitive and characterized by rapid technological progress, frequent new product introductions, changes in customer requirements and evolving industry standards. We believe the principal competitive factors in the network switching market are:

We believe that we compete with our competitors with respect to many of the foregoing factors. However, the market for network switching solutions is dominated by a few large companies, particularly Brocade Communications Systems, Inc., Cisco Systems, Inc., Hewlett-Packard Company, Huawei, and Juniper Networks Inc. Most of these competitors have longer operating histories, greater name recognition, larger customer bases, broader product lines and substantially greater financial, technical, sales, marketing and other resources.

Environmental Matters

We are subject to various environmental and other regulations governing product safety, materials usage, packaging and other environmental impacts in the United States and in various countries where our products are manufactured and sold. To date, compliance with federal, state, local, and foreign laws enacted for the protection of the environment has had no material effect on our capital expenditures, earnings, or competitive position.

We are committed to energy efficiency in our product lines. For example, some of our products consume less power than offerings from our major competitors under normal operations. Accordingly, we believe this is an area that affords us a competitive advantage for our products in the marketplace. We maintain compliance with various regulations related to the environment, including the Waste Electrical and Electronic Equipment and Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment regulations adopted by the European Union. To date, our compliance efforts with various U.S. and foreign regulations related to the environment has not had a material effect on our operating results.

Employees

As of June 30, 2013 , we employed 625 people, including 262 in sales and marketing, 191 in research and development, 76 in operations, 49 in customer support and service, and 47 in finance and administration. We have never had a work stoppage and no U.S. personnel are represented under collective bargaining agreements. We consider our employee relations to be good.

We believe that our future success depends on our continued ability to attract, integrate, retain, train and motivate highly qualified personnel, and upon the continued service of our senior management and key personnel. None of our executive officers or key employees is bound by an employment agreement which mandates that the employee render services for any specific term. The market for qualified personnel is competitive.

Item 1A. Risk Factors

The following is a list of risks and uncertainties which may have a material and adverse effect on our business, financial condition or results of operations. The risks and uncertainties set out below are not the only risks and uncertainties we face, and some are endemic to the networking industry.

We cannot assure you that we will be profitable in the future because a number of factors could negatively affect our financial results.

We have a limited history of profitability and have reported losses in some of our prior fiscal years. In addition, in years when we reported profits, we were not profitable in each quarter during those years. We anticipate continuing to incur significant sales and marketing, product development and general and administrative expenses. Any delay in generating or recognizing revenue could result in a loss for a quarter or full year. Even if we are profitable, our operating results may fall below our expectations and those of our investors, which could cause the price of our stock to fall.

We may experience challenges or delays in generating or recognizing revenue for a number of reasons and our revenue and operating results have varied significantly in the past and may vary significantly in the future due to a number of factors, including, but not limited to, the following:

Due to the foregoing factors, period-to-period comparisons of our operating results should not be relied upon as an indicator of our future performance.

We purchase several key components for products from single or limited sources and could lose sales if these suppliers fail to meet our needs.

We currently purchase several key components used in the manufacture of our products from single or limited sources and are dependent upon supply from these sources to meet our needs. Certain components such as tantalum capacitors, SRAM, DRAM, and printed circuit boards, have been in the past, and may in the future be, in short supply. We have encountered, and are likely in the future to encounter, shortages and delays in obtaining these or other components, and this could have a material adverse effect on our ability to meet customer orders. Our principal sole-source components include:

Our principal limited-source components include:

We use our forecast of expected demand to determine our material requirements. Lead times for materials and components we order vary significantly, and depend on factors such as the specific supplier, contract terms and demand for a component at a given time. If forecasts exceed orders, we may have excess and/or obsolete inventory, which could have a material adverse effect on our operating results and financial condition. If orders exceed forecasts, we may have inadequate supplies of certain materials and components, which could have a material adverse effect on our ability to meet customer delivery requirements and to recognize revenue.

Generally, we do not have agreements fixing long-term prices or minimum volume requirements from suppliers. From time to time we have experienced shortages and allocations of certain components, resulting in delays in filling orders. Qualifying new suppliers to compensate for such shortages may be time-consuming and costly, and may increase the likelihood of errors in design or production. In addition, during the development of our products, we have experienced delays in the prototyping of our chipsets, which in turn has led to delays in product introductions. Similar delays may occur in the future. Furthermore, the performance of the components as incorporated in our products may not meet the quality requirements of our customers.

Intense competition in the market for networking equipment could prevent us from increasing revenue and maintaining profitability.

The market for network switching solutions is intensely competitive and dominated primarily by Brocade Communications Systems, Inc., Cisco Systems Inc., Dell, Hewlett-Packard Company, Huawei, and Juniper Networks, Inc. Most of our competitors have longer operating histories, greater name recognition, larger customer bases, broader product lines and substantially greater financial, technical, sales, marketing and other resources. As a result, these competitors are able to devote greater resources to the development, promotion, sale and support of their products. In addition, they have larger distribution channels, stronger brand names, access to more customers, a larger installed customer base and a greater ability to make attractive offers to channel partners and customers than we do. For example, we have encountered, and expect to continue to encounter, many potential customers who are confident in and committed to the product offerings of our principal competitors. Accordingly, these potential customers may not consider or evaluate our products. When such potential customers have considered or evaluated our products, we have in the past lost, and expect in the future to lose, sales to some of these customers as large competitors have offered significant price discounts to secure these sales.

The pricing policies of our competitors impact the overall demand for our products and services. Some of our competitors are capable of operating at significant losses for extended periods of time, increasing pricing pressure on our products and services. If we do not maintain competitive pricing, the demand for our products and services, as well as our market share, may decline. From time to time, we may lower the prices of our products and services in response to competitive pressure. When this happens,

if we are unable to reduce our component costs or improve operating efficiencies, our revenue and margins will be adversely affected.

We may engage in future acquisitions that dilute the ownership interests of our stockholders, cause us to incur debt and assume contingent liabilities.

As part of our business strategy, we review acquisition and strategic investment prospects that we believe would complement our current product offerings, augment our market coverage or enhance our technical capabilities, or otherwise offer growth opportunities. In the event of any future acquisitions, we could:

These actions could have a material adverse effect on our operating results or the price of our common stock. Moreover, even if we do obtain benefits in the form of increased sales and earnings, these benefits may be recognized much later than the time when the expenses associated with an acquisition are incurred. This is particularly relevant in cases where it would be necessary to integrate new types of technology into our existing portfolio and new types of products may be targeted for potential customers with which we do not have pre-existing relationships. Acquisitions and investment activities also entail numerous risks, including:

We may not be able to successfully integrate any businesses, products, technologies, or personnel that we might acquire in the future, and our failure to do so could have a material adverse effect on our business, operating results and financial condition.

We may not fully realize the anticipated positive impacts to future financial results from our restructuring efforts.

We recently undertook restructuring efforts to streamline operations and reduce operating expenses. Our ability to achieve the anticipated cost savings and other benefits from our restructuring efforts within expected time frames is subject to many estimates and assumptions, and may vary materially based on factors such as market conditions and the effect of our restructuring efforts on our work force. These estimates and assumptions are subject to significant economic, competitive and other uncertainties, some of which are beyond our control. There can be no assurance that we will fully realize the anticipated positive impacts to future financial results from our current or future restructuring efforts. If our estimates and assumptions are incorrect or if other unforeseen events occur, we may not achieve the cost savings expected from such restructurings, and our business and results of operations could be adversely affected.

Industry consolidation may lead to stronger competition and may harm our operating results.

There has been a trend toward industry consolidation in our markets for several years. We expect this trend to continue as companies attempt to strengthen or hold their market positions in an evolving industry and as companies are acquired or are unable to continue operations. For example, some of our current and potential competitors for enterprise data center business have made acquisitions, or announced new strategic alliances, designed to position them with the ability to provide end-to-end technology solutions for the enterprise data center. Companies that are strategic alliance partners in some areas of our business may acquire or form alliances with our competitors, thereby reducing their business with us. We believe that industry consolidation may result in stronger competitors that are better able to compete as sole-source vendors for customers. This could lead to more variability in our operating results and could have a material adverse effect on our business, operating results, and financial condition. Furthermore, particularly in the service provider market, rapid consolidation will lead to fewer customers, with the effect that loss of a major customer could have a material impact on results not anticipated in a customer marketplace composed of more numerous participants.

We intend to invest in engineering, sales, service, marketing and manufacturing on a long term basis, and delays or inability to attain the expected benefits may result in unfavorable operating results.

While we intend to focus on managing our costs and expenses, over the long term, we also intend to invest in personnel and other resources related to our engineering, sales, service, marketing and manufacturing functions as we focus on our foundational priorities, such as leadership in our core products and solutions and architectures for business transformation. We are likely to recognize the costs associated with these investments earlier than some of the anticipated benefits and the return on these investments may be lower, or may develop more slowly, than we expect. If we do not achieve the benefits anticipated from these investments, or if the achievement of these benefits is delayed, our operating results may be adversely affected.

We expect the average selling prices of our products to decrease, which may reduce gross margin and/or revenue.

The network equipment industry has traditionally experienced an erosion of average selling prices due to a number of factors, including competitive pricing pressures, promotional pricing and technological progress. We anticipate that the average selling prices of our products will decrease in the future in response to competitive pricing pressures, excess inventories, increased sales discounts and new product introductions by us or our competitors. We may experience decreases in future operating results due to the erosion of our average selling prices. To maintain our gross margin, we must develop and introduce on a timely basis new products and product enhancements and continually reduce our product costs. Our failure to do so would likely cause our revenue and gross margin to decline.

Our success is dependent on our ability to continually introduce new products and features that achieve broad market acceptance.

The network equipment market is characterized by rapid technological progress, frequent new product introductions, changes in customer requirements and evolving industry standards. If we do not regularly introduce new products in this dynamic environment, our product lines will become obsolete. These new products must be compatible and inter-operate with products and architectures offered by other vendors. We have and may in the future experience delays in product development and releases, and such delays have and could in the future adversely affect our ability to compete and our operating results.

When we announce new products or product enhancements or end of sale existing products that have the potential to replace or shorten the life cycle of our existing products, customers may defer or cancel orders for our existing products. These actions could have a material adverse effect on our operating results by unexpectedly decreasing sales, increasing inventory levels of older products and exposing us to greater risk of product obsolescence.

Even if we introduce new switching products, alternative technologies could achieve widespread market acceptance and displace the Ethernet technology on which we have based our product architecture. For example, developments in routers and routing software could significantly reduce demand for our products. As a result, we may not be able to achieve widespread market acceptance of our current or future products.

The unfavorable economic environment has and may continue to negatively impact our business and operating results.

The challenges and uncertainty currently affecting global economic conditions may negatively impact our business and operating results in the following ways:

If global economic conditions do not show continued improvement, we believe that we could experience material adverse impacts to our business and operating results.

Claims of infringement by others may increase and the resolution of such claims may adversely affect our operating results.

Our industry is characterized by the existence of a large number of patents and frequent claims and related litigation regarding patents, copyrights (including rights to "open source" software), and other intellectual property rights. Because of the existence of a large number of patents in the networking field, the secrecy of some pending patents and the issuance of new patents at a rapid pace, it is not possible to determine in advance if a product or component might infringe the patent rights of others. Because of the potential for courts awarding substantial damages and the lack of predictability of such awards, it is not uncommon for companies in our industry to settle even potentially unmeritorious claims for very substantial amounts. Further, the entities with whom we have or could have disputes or discussions include entities with extensive patent portfolios and substantial financial assets. These entities are actively engaged in programs to generate substantial revenue from their patent portfolios and are seeking or may seek significant payments or royalties from us and others in our industry.

Litigation resulting from claims that we are infringing the proprietary rights of others has resulted and could in the future result in substantial costs and a diversion of resources, and could have a material adverse effect on our business, financial condition and results of operations. We have received notices from entities alleging that we may be infringing their patents, and we are currently parties to patent litigation as described under Part I, Item 3, Legal Proceedings. Without regard to the merits of these or any other claims, an adverse court order or a settlement could require us, among other actions, to:

In addition, our products include so-called "open source" software. Open source software is typically licensed for use at no initial charge, but imposes on the user of the open source software certain requirements to license to others both the open source software as well as modifications to the open source software. Our use of open source software subjects us to certain additional risks for the following reasons:

We believe that even if we do not infringe the rights of others, we will incur significant expenses in the future due to disputes or licensing negotiations, though the amounts cannot be determined. These expenses may be material or otherwise adversely affect our operating results.

Our operating results may be negatively affected by defending or pursuing claims or lawsuits.

We have and may in the future pursue or be subject to claims or lawsuits in the normal course of our business. In addition to the intellectual property lawsuits described above, we are currently parties to securities and contract litigation as described in Part I, Item 3. Legal Proceedings. Regardless of the result, litigation can be expensive, lengthy and disruptive to normal business operations. Moreover, the results of complex legal proceedings are difficult to predict. An unfavorable resolution of a lawsuit in which we are a defendant could result in a court order against us or payments to other parties that would have an adverse effect on our business, results of operations, or financial condition. Even if we are successful in prosecuting claims and lawsuits, we may not recover damages sufficient to cover our expenses incurred to manage, investigate and pursue the litigation. In addition, subject to certain limitations, we may be obligated to indemnify our current and former directors, officers and employees in certain lawsuits. We do not maintain insurance coverage which will cover all of our litigation costs and liabilities.

If we fail to protect our intellectual property, our business could suffer.

We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. However, we cannot ensure that the actions we have taken will adequately protect our intellectual property rights or that other parties will not independently develop similar or competing products that do not infringe on our patents. We generally enter into confidentiality or license agreements with our employees, consultants and corporate partners, and control access to and distribution of our intellectual property and other proprietary information. Despite our efforts to protect our

proprietary rights, unauthorized parties may attempt to copy or otherwise misappropriate or use our products or technology, which would adversely affect our business.

When our products contain undetected errors, we may incur significant unexpected expenses and could lose sales.

Network products frequently contain undetected errors when new products or new versions or updates of existing products are released to the marketplace. In the past, we have experienced such errors in connection with new products and product updates. We have experienced component problems in prior years that caused us to incur higher than expected warranty, service costs and expenses, and other related operating expenses. In the future, we expect that, from time to time, such errors or component failures will be found in new or existing products after the commencement of commercial shipments. These problems may have a material adverse effect on our business by causing us to incur significant warranty, repair and replacement costs, diverting the attention of our engineering personnel from new product development efforts, delaying the recognition of revenue and causing significant customer relations problems. Further, if products are not accepted by customers due to such defects, and such returns exceed the amount we accrued for defective returns based on our historical experience, our operating results would be adversely affected.

Our products must successfully interoperate with products from other vendors. As a result, when problems occur in a network, it may be difficult to identify the sources of these problems. The occurrence of system errors, whether or not caused by our products, could result in the delay or loss of market acceptance of our products and any necessary revisions may cause us to incur significant expenses. The occurrence of any such problems would likely have a material adverse effect on our business, operating results and financial condition.

Our dependence on one manufacturer for our manufacturing requirements could harm our operating results.

We primarily rely on one manufacturing partner, Alpha Networks, Inc. headquartered in Hsinchu, Taiwan, to manufacture our products. We have experienced delays in product shipments from our manufacturing partner in the past, which in turn delayed product shipments to our customers. These or similar problems may arise in the future, such as delivery of products of inferior quality, delivery of insufficient quantity of products, or the interruption or discontinuance of operations of a manufacturer, any of which could have a material adverse effect on our business and operating results. In addition, any natural disaster or business interruption to our manufacturing partner could significantly disrupt our business. While we maintain strong relationships with our manufacturing partner, our agreements with this manufacturer are generally of limited duration and pricing, quality and volume commitments are negotiated on a recurring basis. The failure to maintain continuing agreements with our manufacturing partner could adversely affect our business. We intend to introduce new products and product enhancements, which will require that we rapidly achieve volume production by coordinating our efforts with those of our suppliers and contract manufacturer.

As part of our cost-reduction efforts, we will need to realize lower per unit product costs from our manufacturing partner by means of volume efficiencies and the utilization of manufacturing sites in lower-cost geographies. However, we cannot be certain when or if such price reductions will occur. The failure to obtain such price reductions would adversely affect our gross margins and operating results.

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 Section 1502 (the "Dodd-Frank Act") requires certain public companies to disclose whether certain minerals, commonly known as "conflict minerals," are necessary to the functionality or production of a product manufactured by those companies and if those minerals originated in the Democratic Republic of the Congo (DRC) or an adjoining country. It may be possible that conflict minerals may be part of the supply chain in the electronics industry and contained in our products. To comply with the Dodd-Frank Act, as determined by the U.S. Securities and Exchange Commission, we will be required to perform due diligence and disclose whether or not our products contain such minerals and from which countries and source (smelter)the minerals were obtained. The implementation of these requirements by government regulators and our partners and/or customers could adversely affect the sourcing, availability, and pricing of minerals used in the manufacture of certain components used in our products. In addition, we will incur additional costs to comply with the disclosure requirements for conflict minerals, including costs related to determining the source of any of the relevant minerals and metals used in our products. As a result, our business and financial results could be harmed.

Our dependence on an OEM for all of our wireless products could harm our operating results.

We rely on Motorola to provide our wireless products. If we experience delays in product shipments from our OEM or if they experience delays from their suppliers, which in turn delays product shipments to our customers, our financial results could be negatively impacted. Problems such as delivery of products of inferior quality, delivery of insufficient quantity of products, or the interruption or discontinuance of operations of our OEM, may arise in the future, any of which could have a material adverse effect on our business and operating results.

We depend upon international sales for a significant portion of our revenue which imposes a number of risks on our business.

International sales constitute a significant portion of our net revenue. Our ability to grow will depend in part on the expansion of international sales. Our international sales primarily depend on the success of our resellers and distributors. The failure of these resellers and distributors to sell our products internationally would limit our ability to sustain and grow our revenue. There are a number of risks arising from our international business, including:

All of our international sales are U.S. dollar-denominated. Future increases in the value of the U.S. dollar relative to foreign currencies could make our products less competitive in international markets. In the future, we may elect to invoice some of our international customers in local currency, which would expose us to fluctuations in exchange rates between the U.S. dollar and the particular local currency. If we do so, we may decide to engage in hedging transactions to minimize the risk of such fluctuations.

We have entered into foreign exchange forward contracts to offset the impact of payment of operating expenses in local currencies to some of our operating foreign subsidiaries. However, if we are not successful in managing these foreign currency transactions, we could incur losses from these activities.

We must continue to develop and increase the productivity of our indirect distribution channels to increase net revenue and improve our operating results.

Our distribution strategy focuses primarily on developing and increasing the productivity of our indirect distribution channels. If we fail to develop and cultivate relationships with significant channel partners, or if these channel partners are not successful in their sales efforts, sales of our products may decrease and our operating results could suffer. Many of our channel partners also sell products from other vendors that compete with our products. Our channel partners may not continue to market or sell our products effectively or to devote the resources necessary to provide us with effective sales, marketing and technical support. We may not be able to successfully manage our sales channels or enter into additional reseller and/or distribution agreements. Our failure to do any of these could limit our ability to grow or sustain revenue.

Our operating results for any given period have and will continue to depend to a significant extent on large orders from a relatively small number of channel partners and other customers. However, we do not have binding purchase commitments from any of them. A substantial reduction or delay in sales of our products to a significant reseller, distributor or other customer could harm our business, operating results and financial condition because our expense levels are based on our expectations as to future revenue and to a large extent are fixed in the short term. Under specified conditions, some third-party distributors are allowed to return products to us and unexpected returns could adversely affect our results.

The sales cycle for our products is long and we may incur substantial non-recoverable expenses or devote significant resources to sales that do not occur when anticipated.

Our products represent a significant strategic decision by a customer regarding its communications infrastructure. The decision by customers to purchase our products is often based on the results of a variety of internal procedures associated with the evaluation, testing, implementation and acceptance of new technologies. Accordingly, the product evaluation process frequently

results in a lengthy sales cycle, typically ranging from three months to longer than a year, and as a result, our ability to sell products is subject to a number of significant risks, including risks that:

To successfully manage our business or achieve our goals, we must attract, retain, train, motivate, develop and promote key employees, and failure to do so can harm us.

Our success depends to a significant degree upon the continued contributions of our key management, engineering, sales and marketing, service and operations personnel, many of whom would be difficult to replace. We do not have employment contracts with these individuals that mandate that they render services for any specific term, nor do we carry life insurance on any of our key personnel. We have experienced and may in the future experience significant turnover in our executive personnel. In addition, retention has generally become more difficult for us, in part because the exercise price of most of the stock options granted to many of our employees is below the market price. As a result, we experienced high levels of attrition. We believe our future success will also depend in large part upon our ability to attract and retain highly skilled managerial, engineering, sales and marketing, service, finance and operations personnel. The market for these personnel is competitive, and we have had difficulty in hiring employees, particularly engineers, in the time-frame we desire.

Companies in the networking industry whose employees accept positions with competitors frequently claim that competitors have engaged in unfair hiring practices. We have from time to time been involved in claims like this with other companies and, although to date they have not resulted in material litigation, we do not know whether we will be involved in additional claims in the future. We could incur substantial costs in litigating any such claims, regardless of the merits.

Failure to successfully expand our sales and support teams or educate them in regard to technologies and our product families may harm our operating results.

The sale of our products and services requires a concerted effort that is frequently targeted at several levels within a prospective customer's organization. We may not be able to increase net revenue unless we expand our sales and support teams in order to address all of the customer requirements necessary to sell our products.

We cannot assure you that we will be able to successfully integrate employees into our company or to educate current and future employees in regard to rapidly evolving technologies and our product families. A failure to do so may hurt our revenue growth and operating results.

Failure of our products to comply with evolving industry standards and complex government regulations may adversely impact our business.

If we do not comply with existing or evolving industry standards and government regulations, we may not be able to sell our products where these standards or regulations apply. The network equipment industry in which we compete is characterized by rapid changes in technology and customers' requirements and evolving industry standards. As a result, our success depends on:

In the past, we have introduced new products that were not compatible with certain technological standards, and in the future, we may not be able to effectively address the compatibility and interoperability issues that arise as a result of technological changes and evolving industry standards.

Our products must also comply with various U.S. federal government regulations and standards defined by agencies such as the Federal Communications Commission, standards established by governmental authorities in various foreign countries and

recommendations of the International Telecommunication Union. In some circumstances, we must obtain regulatory approvals or certificates of compliance before we can offer or distribute our products in certain jurisdictions or to certain customers. Complying with new regulations or obtaining certifications can be costly and disruptive to our business.

If we do not comply with existing or evolving industry standards or government regulations, we will not be able to sell our products where these standards or regulations apply, which may prevent us from sustaining our net revenue or achieving profitability.

Changes in the effective tax rate including from the release of the valuation allowance recorded against our net U.S. deferred tax assets, or adverse outcomes resulting from examination of our income or other tax returns or change in ownership, could adversely affect our results.

Our future effective tax rates may be volatile or adversely affected by changes in our business or U.S. or foreign tax laws, including: the partial or full release of the valuation allowance recorded against our net U.S. deferred tax assets; expiration of or lapses in the research and development tax credit laws; transfer pricing adjustments; tax effects of stock-based compensation; or costs related to restructurings. In addition, we are subject to the examination of our income tax returns by the Internal Revenue Service and other tax authorities. Although we regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes, there is no assurance that such determinations by us are in fact adequate. Changes in our effective tax rates or amounts assessed upon examination of our tax returns may have a material, adverse impact on our cash flows and our financial condition.

Our future effective tax rate in particular could be adversely affected by a change in ownership pursuant to U.S. Internal Revenue Code Section 382. If a change in ownership occurs, it may limit our ability to utilize our net operating losses to offset our U.S. taxable income. If U.S. taxable income is greater than the change in ownership limitation, we will pay a higher rate of tax with respect to the amount of taxable income that exceeds the limitation. This could have a material adverse impact on our results of operations. On April 26, 2012, we adopted an Amended and Restated Rights Agreement to help protect our assets (the "Rights Agreement"). In general, this does not allow a stockholder to acquire more than 4.95% of our outstanding common stock without a waiver from our board of directors, who must take into account the relevant tax analysis relating to potential limitation of our net operating losses. The Rights Agreement is effective through April 30, 2014.

If we do not adequately manage and evolve our financial reporting and managerial systems and processes, our ability to manage and grow our business may be harmed.

Our ability to successfully implement our business plan and comply with regulations requires an effective planning and management process. We need to continue improving our existing, and implement new, operational and financial systems, procedures and controls. Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls, could harm our ability to record and report financial and management information on a timely and accurate basis, or to forecast future results.

Compliance with laws, rules and regulations relating to corporate governance and public disclosure may result in additional expenses.

Federal securities laws, rules and regulations, as well as NASDAQ rules and regulations, require companies to maintain extensive corporate governance measures, impose comprehensive reporting and disclosure requirements, set strict independence and financial expertise standards for audit and other committee members and impose civil and criminal penalties for companies and their Chief Executive Officers, Chief Financial Officers and directors for securities law violations. These laws, rules and regulations and the interpretation of these requirements are evolving, and we are making investments to evaluate current practices and to continue to achieve compliance.

Our headquarters and some significant supporting businesses are located in northern California and other areas subject to natural disasters that could disrupt our operations and harm our business.

Our corporate headquarters are located in Silicon Valley in Northern California. Historically, this region as well as our R&D center in North Carolina has been vulnerable to natural disasters and other risks, such as earthquakes, fires, floods and tropical storms, which at times have disrupted the local economy and posed physical risks to our property. We have contract manufacturers located in Taiwan where similar natural disasters and other risks may disrupt the local economy and pose physical risks to our property and the property of our contract manufacturer.

In addition, the continued threat of terrorism and heightened security and military action in response to this threat, or any future acts of terrorism, may cause further disruptions to the economies of the U.S. and other countries. If such disruptions result in delays or cancellations of customer orders for our products, our business and operating results will suffer.

We currently do not have redundant, multiple site capacity in the event of a natural disaster, terrorist act or other catastrophic event. In the event of such an occurrence, our business would suffer.

Our stock price has been volatile in the past and our stock price may significantly fluctuate in the future.

In the past, our common stock price has fluctuated significantly. This could continue as we or our competitors announce new products, our results or those of our customers or competition fluctuate, conditions in the networking or semiconductor industry change, or when investors, change their sentiment toward stocks in the networking technology sector.

In addition, fluctuations in our stock price and our price-to-earnings multiple may make our stock attractive to momentum, hedge or day-trading investors who often shift funds into and out of stock rapidly, exacerbating price fluctuations in either direction, particularly when viewed on a quarterly basis.

Provisions in our charter documents and Delaware law and our adoption of a stockholder rights plan may delay or prevent an acquisition of Extreme, which could decrease the value of our Common Stock.

Our certificate of incorporation and bylaws and Delaware law contain provisions that could make it more difficult for a third party to acquire us without the consent of our Board of Directors. Delaware law also imposes some restrictions on mergers and other business combinations between us and any holder of 15% or more of our outstanding common stock. In addition, our Board of Directors has the right to issue preferred stock without stockholder approval, which could be used to dilute the stock ownership of a potential hostile acquirer. Although we believe these provisions of our certificate of incorporation and bylaws and Delaware law will provide for an opportunity to receive a higher bid by requiring potential acquirers to negotiate with our Board of Directors, these provisions apply even if the offer may be considered beneficial by some of our stockholders.

Our Rights Agreement provides that if a single stockholder (or group) acquires more than 4.95% of our outstanding common stock without a waiver from our Board of Directors, each holder of one share of our common stock (other than the stockholder or group who acquired in excess of 4.95% of our common stock) may purchase a fractional share of our preferred stock that would result in substantial dilution to the triggering stockholder or group. Accordingly, although this plan is designed to prevent any limitation on the utilization of our net operating losses by avoiding issues raised under Section 382 of the U.S. Internal Revenue Code, the Rights Agreement could also serve as a deterrent to stockholders wishing to effect a change of control.

We rely on the availability of third-party licenses

Some of our products are designed to include software or other intellectual property licensed from third parties. It may be necessary in the future to seek or renew licenses relating to various aspects of these products. There can be no assurance that the necessary licenses would be available on acceptable terms, if at all. The inability to obtain certain licenses or other rights or to obtain such licenses or rights on favorable terms, or the need to engage in litigation regarding these matters, could have a material adverse effect on our business, operating results, and financial condition. Moreover, the inclusion in our products of software or other intellectual property licensed from third parties on a nonexclusive basis could limit our ability to protect our proprietary rights in our products.

Market conditions and changes in the industry could lead to discontinuation of our products or businesses resulting in asset impairments

In response to changes in industry and market conditions, we may be required to strategically realign our resources and consider restructuring, disposing of, or otherwise exiting businesses. Any decision to limit investment in or dispose of or otherwise exit businesses may result in the recording of special charges, such as inventory and technology-related write-offs, workforce reduction costs, charges relating to consolidation of excess facilities, or claims from third parties who were resellers or users of discontinued products. Our estimates with respect to the useful life or ultimate recoverability of our carrying basis of assets, including purchased intangible assets, could change as a result of such assessments and decisions. Although in certain instances, our supply agreements allow us the option to cancel, reschedule, and adjust our requirements based on our business needs prior to firm orders being placed, our loss contingencies may include liabilities for contracts that we cannot cancel with contract manufacturers and suppliers. Further, our estimates relating to the liabilities for excess facilities are affected by changes in real estate market conditions.

If our products do not effectively inter-operate with our customers' networks and result in cancellations and delays of installations our business could be harmed.

Our products are designed to interface with our customers' existing networks, each of which have different specifications and utilize multiple protocol standards and products from other vendors. Many of our customers' networks contain multiple generations of products that have been added over time as these networks have grown and evolved. Our products must inter-operate with many or all of the products within these networks as well as future products in order to meet our customers' requirements. If we find errors in the existing software or defects in the hardware used in our customers' networks, we may need to modify our software or hardware to fix or overcome these errors so that our products will inter-operate and scale with the

existing software and hardware, which could be costly and could negatively affect our business, financial condition, and results of operations. In addition, if our products do not inter-operate with those of our customers' networks, demand for our products could be adversely affected or orders for our products could be cancelled. This could hurt our operating results, damage our reputation, and seriously harm our business and prospects.

System security risks, data protection breaches, and cyber-attacks could compromise our proprietary information, disrupt our internal operations and harm public perception of our products, which could adversely affect our business.

In the ordinary course of business, we store sensitive data, including intellectual property, our proprietary business information and that of our customers, suppliers and business partners on our networks. The secure maintenance of this information is critical to our operations and business strategy. Increasingly, companies, including Extreme Networks, are subject to a wide variety of attacks on their networks on an ongoing basis. Despite our security measures, Extreme Networks' information technology and infrastructure may be vulnerable to penetration or attacks by computer programmers and hackers, or breached due to employee error, malfeasance or other disruptions. Any such breach could compromise our networks, creating system disruptions or slowdowns and exploiting security vulnerabilities of our products, and the information stored on our networks could be accessed, publicly disclosed, lost or stolen, which could subject us to liability to our customers, suppliers, business partners and others, and cause us reputational and financial harm. In addition, sophisticated hardware and operating system software and applications that we produce or procure from third parties may contain defects in design or manufacture, including "bugs" and other problems that could unexpectedly interfere with the operation of our networks.

If an actual or perceived breach of network security occurs in our network or in the network of a customer of our networking products, regardless of whether the breach is attributable to our products, the market perception of the effectiveness of our products could be harmed. In addition, the economic costs to us to eliminate or alleviate cyber or other security problems, bugs, viruses, worms, malicious software systems and security vulnerabilities could be significant and may be difficult to anticipate or measure. Because the techniques used by computer programmers and hackers, many of whom are highly sophisticated and well-funded, to access or sabotage networks change frequently and generally are not recognized until after they are used, we may be unable to anticipate or immediately detect these techniques. This could impede our sales, manufacturing, distribution or other critical functions, which could adversely affect our business.

Item 2. Properties

Our principal administrative, sales, and marketing facilities are located in San Jose, California. We started leasing our current headquarters in June 2013. We also lease office space and executive suites in various other geographic locations domestically and internationally for research & development, sales and service personnel and administration. Our aggregate lease expense for fiscal 2013 was approximately $5.9 million.

On September 11, 2012, we completed the sale of our former headquarters and accompanying 16 acres of land in Santa Clara, California for net cash proceeds of approximately $44.7 million. On September 12, 2012, we entered into an agreement with the buyer, whereby we leased three of the four buildings, comprising of the campus, under a cancellable lease arrangement expiring on January 31, 2013 for one building and on August 31, 2014 for the remaining two buildings. The lease was terminable by us upon 30 days' notice at any time before the lease expiration date. We terminated the lease on June 30, 2013.

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

Business Overview

We develop and sell network infrastructure equipment and offer related services contracts for extended warranty and maintenance to our enterprise, data center and service provider customers. Substantially all of our revenue is derived from the sale of our networking equipment and related service contracts.

We believe that understanding the following key developments is helpful to an understanding of our operating results for the fiscal year ended June 30, 2013 .

Impact of the Global Economic Developments

We believe that the credit market crisis, slow economic recovery in the United States and Europe, and other challenges affecting global economic conditions placed significant limitations on our financial performance. We operate in three regions: Americas, which includes the United States, Canada, Mexico, Central America and South America; EMEA, which includes Europe, Middle East, and Africa; and APAC which includes Asia Pacific, South Asia, Japan and Australia. Sales in the APAC and some European countries were most impacted as a result of the soft global economy. We believe that conservative purchasing patterns and delays or cancellation of IT infrastructure plans in the face of continued uncertainty regarding the global economy, may continue to negatively impact overall demand for networking solutions, including Ethernet equipment.

We have taken, and plan to continue to take, other steps to manage our business in the current economic environment. For example, we have managed from time to time our contingent work force, reduced travel and other discretionary spending, realigned our product portfolio and organization to grow revenue and operating income, and controlled all hiring activities.

Increasing Demand for Bandwidth

We believe that the continued increase in demand for bandwidth will over time drive future demand for high performance Ethernet solutions. Wide-spread adoption of electronic communications in all aspects of our lives, proliferation of next generation converged mobile devices and deployment of triple-play services to residences and businesses alike, continues to generate demand for greater network performance across broader geographic locations. In parallel to these transformational forces within society and the community at large, the accelerating adoption of internet and intranet "cloud" solutions within business enterprises is enabling organizations to offer greater business scalability to improve efficiency and through more effective operations, improve profitability. In order to realize the benefits of these developments, customers require additional bandwidth and high performance from their network infrastructure at affordable prices. We are seeing the initial indications that the Ethernet segment of the networking equipment market will return to growth as enterprise, data center and carrier customers continue to recognize the performance and operating cost benefits of Ethernet technology.

Expanding Product Portfolio

We believe that continued success in our marketplace is dependent upon a variety of factors that includes, but is not limited to, our ability to design, develop and distribute new and enhanced products employing leading-edge technology. Over the past few years, we further extended our Ethernet product portfolio through continued evolutions of our BlackDiamond BD-X, a highly-scalable core switch for IT and cloud data centers, the Summit X440 for the intelligent edge, the Summit X670 for data center top-of-rack deployments, the E4G Cell Site Router family for mobile backhaul, as well as introducing a revamp of our RidgeLine network management platform. We also introduced the Summit X430, further extending our ExtremeXOS technology into more cost-conscious environments. During fiscal 2013 we also introduced key software functionality that will drive differentiation. This included support for OpenFlow and OpenStack as part of our SDN strategy, automation of IP cameras for physical security, and Audio-Video Bridging, a breakthrough set of technologies for professional audio and video.

Industry Developments

The market for network infrastructure equipment is highly competitive and dominated by a few large companies. The current economic climate has further driven consolidation of vendors within the Ethernet networking market and with vendors from adjacent markets, including storage, security, wireless and voice applications. We believe that the underpinning technology for all of these adjacent markets is Ethernet. As a result, independent Ethernet switch vendors are being acquired or merged with larger, adjacent market vendors to enable them to deliver complete and broad solutions. As an independent Ethernet switch vendor, we must provide products that, when combined with the products of our large strategic partners, create compelling solutions for end-user customers. Our approach is to focus on the intelligence and automation layer that spans our hardware products and that facilitates end-to-end solutions, as opposed to positioning Extreme Networks as a low-cost-vendor with point products. Lower overall market growth has also created an environment of declining margins due to increased competition between the remaining vendors in this space. During the last year, overall Ethernet port counts have grown, while industry revenues have decreased,

signaling a decline in average selling price. Our product life cycle and operational cost reduction efforts are therefore even more critical for margin preservation.

Amendment to Rights Agreement

On November 27, 2012, our Board of Directors adopted an Amended and Restated Rights Agreement between Extreme Networks and Computershare Shareholder Services LLC as the rights agent (the "Restated Rights Plan"). The Restated Rights Plan governs the terms of each right ("Right") that has been issued with respect to each share of Common Stock of Extreme Networks. Each Right initially represents the right to purchase one one-thousandth of a share of Series A Preferred Stock of Extreme Networks. The Restated Rights Plan replaces in its entirety the Rights Agreement, dated as of April 27, 2001, as amended on June 30, 2010; April 26, 2011, between Extreme Networks and Mellon Investor services LLC (the "Prior Rights Plan").

The Board reviewed the necessity of the provision of the Prior Rights Plan adopted to preserve the value of Extreme Networks' deferred tax assets, including its net operating loss carry forwards, with respect to its ability to fully use its tax benefits to offset future income may be limited if it experiences an "ownership change" for purposes of Section 382 of the Internal Revenue Code of 1986 as a result of ordinary buying and selling of Extreme Networks' common stock. Following its review, the Board decided it was necessary and in the best interests of Extreme Networks and its stockholders to enter into the Restated Rights Plan. The Restated Rights Plan incorporates the Prior Rights Plan and the amendments thereto into a single agreement and extended the term of the Prior Rights Plan to April 30, 3013. Our stockholders voted to extend the term of the Restated Rights Plan from April 30, 2013 to April 30, 2014 at our 2012 Annual Meeting of Stockholders, and the Restated Rights Plan was amended effective April 30, 2013 to reflect the extension of the term.

Results of Operations

Effective June 30, 2012, we changed our fiscal period to coincide with calendar month-end. Previously, we used a fiscal 52/53 week manufacturing calendar year. Accordingly, the fiscal year ended June 30, 2012 has 52 weeks compared to 53 weeks in 2011.

Our operations and financial performance have been affected by the economic factors described above, and during fiscal 2013 , we achieved the following results:

Net Revenue

The following table presents net product and service revenue for the fiscal years 2013 , 2012 and 2011 (dollars in thousands):

Product revenue decreased in fiscal 2013 as compared to fiscal 2012 primarily due to weaker than expected demand from our public sector and enterprise customers in the United States and we continued to experience weak demand from our public sector and strategic customers and distributors in the EMEA region attributable to the persistent macroeconomic challenges in Western Europe.

Product revenue decreased in fiscal 2012 as compared to fiscal 2011 primarily due to increased pricing pressure on our products and lower volumes. The decreases were also a result of elimination of certain products and product mix shift.

Service revenue decreased in fiscal 2013 as compared to fiscal 2012 reflecting slight decrease in the levels of service contract renewals.

Service revenue increased in fiscal 2012 as compared to fiscal 2011 resulting from a significant one time renewal contract for a single customer and maintenance contract extensions.

As noted previously, we operate in three regions: Americas, which includes the United States, Canada, Mexico, Central America and South America; EMEA, which includes Europe, Russia, Middle East, and Africa; and APAC which includes Asia Pacific, South Asia, Japan and Australia. Prior to fiscal 2012, South America was included as part of EMEA. The following table presents the total net revenue geographically for the fiscal years 2013 , 2012 and 2011 (dollars in thousands):

Revenue in the EMEA decreased in 2013 as compared to fiscal 2012 primarily due to macroeconomic challenges which affected the demand from customers in those regions. Revenue in the Americas and APAC decreased slightly as compared to fiscal 2012 .

Revenue in the Americas increased in 2012 as compared to fiscal 2011 primarily due to sales to several large customers. Revenue in EMEA decreased in fiscal 2012 as compared to fiscal 2011 due to slow economic recovery in Europe. Revenue in APAC also decreased in fiscal 2012 as compared to fiscal 2011 due to weaker sales in India, Korea, Hong Kong and Japan and organizational changes made in 2012.

We rely upon multiple channels of distribution, including distributors, direct resellers, OEM, and direct sales.  Revenue through our distributor channel was 43% of total product revenue in fiscal 2013 , 42% of total product revenue in fiscal 2012 , and 52% in fiscal 2011 . The decrease in distributor channel revenue from fiscal 2011 was due to a shift in sales from distributors to our OEMs and direct resellers.

The level of sales to any one customer, including a distributor, may vary from period to period.

Cost of Revenue and Gross Profit

The following table presents the gross profit on product and service revenue and the gross profit percentage of net revenue for the fiscal years 2013 , 2012 and 2011 (dollars in thousands):

Cost of product revenue includes costs of materials, amounts paid to third-party contract manufacturers, costs related to warranty obligations, charges for excess and obsolete inventory, royalties under technology license agreements, and internal costs associated with manufacturing overhead, including management, manufacturing engineering, quality assurance, development of test plans, and document control. We outsource substantially all of our manufacturing and supply chain management operations, and we conduct quality assurance, manufacturing engineering, document control and distribution at our facilities in San Jose, California, China, and Taiwan. Accordingly, a significant portion of our cost of product revenue consists of payments to our primary contract manufacturer, Alpha Networks, located in Hsinchu, Taiwan. In addition, we OEM our wireless product line from Motorola.

Product gross profit in fiscal 2013 decreased as compared to fiscal 2012 due to lower product revenue and an increase in charges for excess and obsolete inventory offset by economic benefits realized in our manufacturing costs.

Product gross profit in fiscal 2012 decreased as compared to fiscal 2011 due to lower sales offset by lower material cost, costs associated with inventory write-down charges, and a decrease in inbound freight costs due to our new Hong Kong distribution center which is located closer to our contract manufacturer Alpha Networks.

Our cost of service revenue consists primarily of labor, overhead, repair and freight costs and the cost of spares used in providing support under customer service contracts.

Service gross profit in fiscal 2013 increased as compared to fiscal 2012 primarily due to lower labor costs from our cost reduction initiatives.

Service gross profit in fiscal 2012 increased as compared to fiscal 2011 primarily due to lower return material authorization shipments for legacy chassis products, mix change from higher repair cost chassis products to lower repair cost stackable products.

Operating Expenses

The following table presents operating expenses and operating income (dollars in thousands):

The following table highlights our operating expenses and operating income as a percentage of net revenues:

Research and Development Expenses

Research and development expenses consist primarily of salaries and related personnel expenses, consultant fees and prototype expenses related to the design, development, and testing of our products. Research and development expenses decreased in fiscal 2013 as compared to fiscal 2012 primarily due to lower spending on engineering projects due to differences in timing and pattern of planned engineering project spending as compared to fiscal 2012 .

Research and development expenses decreased in fiscal 2012 as compared to fiscal 2011 primarily due to $3.5 million less in salaries and benefits expense due to a reduction in headcount and a transfer of resources to lower cost regions and $0.9 million less in small equipment expenses due to better utilization of existing test equipment, offset by $0.6 million increase in professional fees related to new product launches.

Sales and Marketing Expenses

Sales and marketing expenses consist of salaries, commissions and related expenses for personnel engaged in marketing and sales functions, as well as trade shows and promotional expenses. Sales and marketing expenses decreased in fiscal 2013 as compared to fiscal 2012 primarily due to lower commissions and reduced personnel costs resulting from lower revenue levels and a reduction in headcount during the year.

Sales and marketing expenses decreased in fiscal 2012 as compared to fiscal 2011 primarily due to $4.5 million reduction in salaries and benefits, $3.5 million reduction in commissions due to lower revenue, $1.7 million less professional fees due to utilization of in-house services, and $1.4 million lesser travel expenses resulting from the reduction in headcount at the beginning of fiscal 2012.

General and Administrative Expenses

General and administrative expenses decreased in fiscal 2013 as compared to fiscal 2012 primarily due to cost reduction initiatives realized as part of the restructuring plan offset by CEO transition expenses of $2.1 million.

General and administrative expenses increased in fiscal 2012 as compared to fiscal 2011 primarily due to increased legal expense of $2.0 million, increased contract labor expense for accounting and finance of $1.0 million, increased stock based compensation expense of $0.8 million, increased international accounting fees of $0.8 million offset by lower salaries and benefits expense of $0.8 million due to fewer headcount. 

Restructuring Charge, Net of Reversal

During fiscal 2013 , 2012 and 2011 , we recorded restructuring charges of $6.8 million , $1.6 million , and $3.8 million , respectively.

Fiscal 2013 Restructuring

During the second quarter of fiscal 2013, we further reduced costs through targeted restructuring activities intended to reduce operating costs and realign our organization in the current competitive environment. As part of our restructuring efforts in the second quarter, we initiated a plan to reduce our worldwide headcount by 13%, consolidate specific global administrative functions, and shift certain operating costs to lower cost regions, among other actions. As of June 30, 2013 , we had restructuring liabilities of $1.1 million related to the fiscal 2013 restructuring, which we anticipate paying by the end of the first quarter of fiscal 2014. We anticipate incurring additional restructuring charges of approximately $0.3 million through the end of the first quarter of fiscal 2014.

Fiscal 2012 Restructuring

During fiscal 2012, we incurred total charges of $2.2 million, including $1.8 million related to severance, $0.1 million of contract termination fees, and $0.2 million other charges. A portion of this restructuring activity was related to the liquidation of our Japan subsidiary with a cost of $0.5 million at June 30, 2012. We substantially liquidated the subsidiary in Japan in the fourth quarter or fiscal 2012, as part of our broad restructuring effort. We disposed of the remaining immaterial assets and liabilities and completed the liquidation process during fiscal 2013. There were no outstanding liabilities related to the fiscal 2012 restructuring as of June 30, 2013 .

Fiscal 2011 Restructuring

During fiscal 2011, we commenced a strategy to focus on growing revenue in specific market verticals and on improving operational effectiveness.  As part of the strategy, we reduced headcount and incurred total restructuring charges of $4.2 million , of which $1.0 million and $3.2 million were recognized in the third and fourth quarter of fiscal 2011, respectively. During the fourth quarter of fiscal 2011, the lease term for the excess leased facilities ended. We recognized a restructuring reversal of $0.4 million related to the true up of operating and rent expenses in fiscal 2012. As of June 30, 2013 , we had restructuring liabilities of $0.4 million remaining related to the fiscal 2011 restructuring, which we anticipate paying during fiscal 2014.

Litigation Settlement

During the third quarter of fiscal 2013, we recognized a litigation charge of $2.5 million related to a settlement agreement with Enterasys Networks.

During the fourth quarter of fiscal 2012, from a judgment related to our lawsuit with Enterasys Networks for patent infringement, we received $0.6 million from Enterasys including a first trial damage award of $0.2 million, reimbursement of legal costs from the first trial of $0.4 million, and interest.

Gain on Sale of Campus

During fiscal 2013, we completed the sale of our corporate campus and accompanying 16 acres of land in Santa Clara, California for net cash proceeds of approximately $44.7 million of which approximately $2.0 million was received in fiscal 2012. We realized a gain of approximately $11.5 million in connection with this transaction, yet recorded a tax loss of approximately $24.6 million.

Interest Income

Interest income was $1.1 million in fiscal 2013 , $1.2 million in fiscal 2012 and $1.3 million in fiscal 2011 , representing a decrease of $0.1 million in fiscal 2013 from fiscal 2012 , and a decrease of $0.1 million in fiscal 2012 from fiscal 2011 . The

decrease in interest income in fiscal 2013 from fiscal 2012 was due to a decrease in the average interest yield from 0.95% in fiscal 2012 to 0.54% in fiscal 2013. The decrease in interest income in fiscal 2012 from fiscal 2011 was due to a decrease in the average interest yield from 1.2% in fiscal 2011 to 0.95% in fiscal 2012.

Interest Expense

We had immaterial interest expense for fiscal 2013 . Interest expense was $0.1 million for both fiscal year 2012 and 2011 . Interest expense in fiscal 2012 and fiscal 2011 were primarily related to interest amortization of technology agreements.

Other Income (Expense), net

Other income (expense) net was expense of $0.6 million in fiscal 2013 , income of $2.0 million in fiscal 2012 and expense of $0.6 million in fiscal 2011 . Other expense in fiscal 2013 was primarily due to the revaluation of certain assets and liabilities denominated in foreign currencies into U.S. dollars.

Other income in fiscal 2012 was primarily comprised of $1.9 million in foreign currency translation gains that were reclassified from other comprehensive income (loss) due to the substantial liquidation of our Japan subsidiary.

Other expense in fiscal 2011 was primarily comprised of foreign currency losses of $0.6 million due to a weaker U.S. dollar.

Provision for Income Taxes

We recorded an income tax provision of $1.7 million for fiscal 2013 . The effective tax rate in fiscal 2013 was 14.8% which differs from the federal statutory tax rate of 35% due primarily to the tax impact of income from foreign operations and the change in valuation allowance. We recorded an income tax provision of $1.7 million for fiscal 2013 due to profits in our foreign subsidiaries, change in U.S. valuation allowance, state taxes, foreign withholding taxes and the release of foreign tax reserves due to a lapse in the statute of limitations on the positions.

The income tax provision of $1.2 million and $1.0 million for fiscal 2012 and 2011 , respectively, were recorded for taxes due on income generated in U.S. federal, certain states and foreign tax jurisdictions. The effective tax rate was 7.0% for fiscal 2012 which differs from the federal statutory tax rate of 35% due primarily to the tax impact of income from foreign operations and the change in valuation allowance.

Critical Accounting Policies and Estimates

Our significant accounting policies are more fully described in Note 2 of Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K. The preparation of consolidated financial statements in accordance with generally accepted accounting principles requires management to make estimates, assumptions and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenue and expenses during the period reported. By their nature, these estimates, assumptions and judgments are subject to an inherent degree of uncertainty. We base our estimates, assumptions and judgments on historical experience, market trends and other factors that are believed to be reasonable under the circumstances. Estimates, assumptions and judgments are reviewed on an ongoing basis and the effects of revisions are reflected in the consolidated financial statements in the period they are determined to be necessary. Actual results may differ from these estimates under different assumptions or conditions. We believe the critical accounting policies stated below, among others, affect our more significant judgments and estimates used in the preparation of our consolidated financial statements.

Share-based Payments

We use the Black-Scholes option-pricing model to determine the fair value of option awards other than performance-based option awards, and share purchase options under our Employee Stock Purchase Plan ("ESPP") on the date of grant with the weighted average assumptions. We use the Monte-Carlo simulation model to determine the fair value and the derived service period of performance-based option awards, with market conditions, on the date of grant. The expected term of options granted is derived from historical data on employee exercise and post-vesting employment termination behavior. The expected term of purchase options under our ESPP represents the contractual life of the ESPP purchase period. The risk-free rate based upon the estimated life of the option and ESPP award is based on the U.S. Treasury yield curve in effect at the time of grant. Expected volatility is based on both the implied volatilities from traded options on our stock and historical volatility on our stock. We do not currently pay cash dividends on our common stock and do not anticipate doing so in the foreseeable future. Accordingly, our expected dividend yield is zero. We are required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. In fiscal 2013, our estimated forfeiture rates based on historical forfeiture experiences are 3% for executives and 9% for non-executive employees. We use the straight-line method for expense attribution, and we only recognize expense for those shares expected to vest.

Revenue Recognition

We derive the majority of our revenue from sales of our networking equipment, with the remaining revenue generated from service fees relating to maintenance service contracts, professional services, and training for our products. We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the price of the product is fixed or determinable, and the collection of the sales proceeds is reasonably assured. In instances where any of the criteria for revenue recognition are not met, we defer revenue until all criteria have been met.

Product revenue from our value-added resellers, non-stocking distributors and end-user customers is recognized at the time of shipment, provided that all of the foregoing revenue recognition requirements have been satisfied. We generally do not grant return privileges, except for defective products during the warranty period, nor do we grant pricing credits. Accordingly, we recognize revenue upon transfer of title and risk of loss to the customer, which is generally upon shipment. We maintain estimated accruals and allowances for sales incentives and other programs that we may make available to our partners, based on historical experience or applicable contractual terms. Shipping costs are included in cost of product revenues. Sales taxes collected from customers are excluded from revenues.

We also sell our products to distributors that stock inventory and sell to resellers. We defer recognition of revenue on all sales to our stocking distributors until the distributors have sold the products, as evidenced by sales data that the distributors provide to us. We grant stocking distributors certain price protection rights and the right to return a portion of unsold inventory for the purpose of stock rotation. The distributor-related deferred revenue and receivables are adjusted at the time of the stock rotation return or price reduction. We also provide stocking distributors with credits for changes in selling prices based on competitive conditions, and provide funding for our distributors and their resellers to perform marketing development activities. We maintain estimated accruals and allowances for these exposures based upon our contractual obligations. Our marketing development channel programs do not meet the criteria for recognizing the costs as marketing expenses and therefore these costs are accrued as a reduction to revenue in the same period that the products are sold.

Revenue from service contracts is deferred and recognized ratably over the contractual service period, which is typically from one to two years. Professional service revenue is recognized upon delivery or completion of performance.

Our networking products are tangible products that contain software and non-software components that function together to deliver the tangible product's essential functionality. Our sales arrangements may contain multiple deliverables comprised of our tangible products, standalone software licenses, and service offerings depending on the distribution sales channel through which the products are sold and the requirements of our customers. We recognize revenue for our multiple deliverable arrangements in accordance with the accounting standard for multiple deliverable revenue arrangements, which provides guidance on whether multiple deliverables exist, how deliverables in an arrangement should be separated, and how consideration should be allocated. The industry-specific software revenue recognition guidance does not apply to the sales of our tangible products. Software revenue guidance is applied to sales of our standalone software products, including software upgrades and software that is not essential to the functionality of the hardware with which it is sold.

Pursuant to the guidance of the accounting standard for multiple-deliverable revenue arrangements, we allocate the total arrangement consideration to each separable element of an arrangement based on the relative selling price of each element. We determine the standalone selling price for each element based on a selling price hierarchy. Under the selling price hierarchy, the selling price for each deliverable is based on our vendor-specific objective evidence of selling price ("VSOE"), which is determined by a substantial majority of our historical standalone sales transactions for a product or service falling within a reasonable range. If VSOE is not available due to a lack of standalone sales transactions or lack of pricing within a narrow range, then third party evidence ("TPE"), as determined by the standalone pricing of competitive vendor products in similar markets, is used. TPE typically is difficult to establish due to the proprietary differences of competitive products and difficulty in obtaining reliable competitive standalone pricing information. When neither VSOE nor TPE is available, we determine the best estimate of standalone selling price ("ESP") for a product or service by considering several factors including, but not limited to, the 12-month historical median sales price, sales channels, geography, gross margin consistency, competitive product pricing, and product life cycle. In consideration of all relevant pricing factors, we apply management judgment to determine the best estimate of selling price through consultation with and formal approval by our management for all products and services for which neither VSOE nor TPE is available. Generally, the standalone selling price of services is determined using VSOE and the standalone selling price of all other deliverables is determined by using ESP. We regularly review VSOE, TPE and ESP for all of our products and services and maintain internal controls over the establishment and updates of these estimates.

Pursuant to the software revenue recognition accounting standard, we continue to recognize revenue for software using the residual method for our sales of standalone software products, including optional software upgrades, and other software that is not essential to the functionality of the hardware with which it is sold. After allocation of the relative selling price to each element of the multiple deliverable arrangement, we recognize revenue in accordance with our policies for product, software, and service revenue recognition.

Our total deferred product revenue from customers other than distributors was $3.1 million and $2.2 million as of June 30, 2013 and June 30, 2012 , respectively. Our total deferred revenue for services, primarily from service contracts, was $38.7 million as of June 30, 2013 and $37.7 million as of June 30, 2012 . Service contracts typically range from one to two years. Shipping costs are included in cost of product revenues.

We provide an allowance for sales returns based on our historical returns, analysis of credit memo data and our return policies. The allowance for sales returns was $0.8 million and $1.3 million as of June 30, 2013 and June 30, 2012 , respectively, for estimated future returns that were recorded as a reduction of our accounts receivable. If the historical data that we use to calculate the estimated sales returns and allowances does not properly reflect future levels of product returns, these estimates will be revised, thus resulting in an impact on future net revenue. We estimate and adjust this allowance at each balance sheet date.

Inventory Valuation

Our inventory balance was $16.2 million as of June 30, 2013 , compared with $26.6 million as of June 30, 2012 . We value our inventory at lower of cost or market. Cost is computed using standard cost, which approximates actual cost, on a first-in, first-out basis. We provide inventory allowances based on excess and obsolete inventories determined primarily by the age of inventory. At the point of the loss recognition, a new, lower-cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. Any written down or obsolete inventory subsequently sold has not had a material impact on gross margin for any of the periods disclosed. Inventory write-downs charged to cost of product revenue were $0.8 million in fiscal 2013 , $1.1 million in fiscal 2012 and $2.2 million in fiscal 2011 .

Long Lived Assets

Long-lived assets include property and equipment, intangible assets, and service inventory which we hold to support customers who have purchased service contracts with a hardware replacement element.   Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets or asset groups may not be recoverable. If such facts and circumstances exist, we assess the recoverability of the long-lived assets by comparing the projected un-discounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. Impairments, if any, are based on the excess of the carrying amount over the fair value of those assets.

Accrued Warranty

Networking products may contain undetected hardware or software errors when new products or new versions or updates of existing products are released to the marketplace. In the past, we had experienced such errors in connection with products and product updates. Our standard hardware warranty period is typically 12 months from the date of shipment to end-users and 90 days for software. For certain access products, we offer a limited lifetime hardware warranty commencing on the date of shipment from us and ending five years following the our announcement of the end of sale of such product. Upon shipment of products to our customers, including both end-users and channel partners, we estimate expenses for the cost to repair or replace products that may be returned under warranty and accrue a liability through charges to cost of product revenue for this amount.

Our accrued warranty balance was $3.3 million and $2.9 million as of June 30, 2013 and June 30, 2012 , respectively. The determination of our warranty requirements is based on our actual historical experience with the product or product family, estimates of repair and replacement costs and any product warranty problems that are identified after shipment. We estimate and adjust this accrual at each balance sheet date in accordance with changes in these factors.

The cost of new warranties issued that was charged to cost of product revenue was $4.3 million in fiscal 2013 , $3.1 million in fiscal 2012 , and $2.4 million in fiscal 2011 .

Accounts Receivable and Allowance for Doubtful Accounts

Our accounts receivable balance, net of allowance for doubtful accounts, was $47.6 million and $41.2 million as of June 30, 2013 and June 30, 2012 , respectively. The allowance for doubtful accounts for trade accounts receivable was $0.5 million and $0.4 million as of June 30, 2013 and June 30, 2012 , respectively. We continually monitor and evaluate the collectability of our trade receivables based on a combination of factors. We record specific allowances for bad debts in general and administrative expense when we become aware of a specific customer's inability to meet its financial obligation to us, such as in the case of bankruptcy filings or deterioration of financial position. Estimates are used in determining our allowances for all other customers based on factors such as current trends in the length of time the receivables are past due and historical collection experience. We mitigate some collection risk by requiring most of our customers in the Asia-Pacific region, excluding Japan and Australia, to pay cash in advance or secure letters of credit when placing an order with us. Our provision for doubtful accounts was an expense of $0.3 million in fiscal 2013 , expense of $0.1 million in fiscal 2012 and benefit of $9,000 in fiscal 2011 .

Deferred Tax Asset Valuation Allowance

We recognize deferred tax assets and liabilities based on the differences between the financial statement carrying amounts and the tax bases of assets and liabilities. Significant management judgment is required in determining our valuation allowance recorded against our net deferred tax assets. We make an assessment of the likelihood that our net deferred tax assets will be recovered from future taxable income, and to the extent that recovery is not believed to be likely, a valuation allowance is established. In fiscal 2013 , the valuation allowance increased by $1.4 million to $142.0 million, and in fiscal 2012 , the valuation allowance decreased by $9.9 million to $140.6 million. We have not provided a valuation allowance against any of our non-U.S. deferred tax assets.

The valuation allowance requires an assessment of both negative and positive evidence when determining the need for a valuation allowance. Evidence, such as operating results during the most recent three-year period was given more weight than our expectations of future profitability, which are inherently uncertain. Our inconsistent history of earnings during those periods coupled with difficulties in forecasting more than one quarter in advance as well as the cyclical nature of our industry represent sufficient negative evidence to require a full valuation allowance against our U.S. federal and state net deferred tax assets. This valuation allowance will be evaluated periodically and can be reversed partially or totally if business results have sufficiently improved to support realization of our deferred tax assets.

Accounting for Uncertainty in Income Taxes

We had unrecognized tax benefits of $10.9 million as of June 30, 2013. If fully recognized in the future, $0.3 million would impact our effective tax rate, and $10.6 million would result in adjustments to deferred tax assets and corresponding adjustments to the valuation allowance. It is reasonably possible that the amount of unrealized tax benefit could decrease by approximately $0.1 million during the next twelve months due to the expiration of the statute of limitations in certain foreign jurisdictions. During the year ended June 30, 2013, we performed a study on our research and development credits documenting the historic credits as prescribed by Internal Revenue Service. As a result of this study we adjusted our available federal and state research credits as well as the amount of these credits that would be unrecognized tax benefits. The credits classified as unrecognized tax benefits decreased by approximately $15.0 million as a result of this study.

Legal Contingencies

We are currently involved in various claims and legal proceedings, including negotiations regarding potential licenses from third parties who have notified us that they believe our products may infringe certain patents. Periodically, we review the status of each significant matter, whether litigation or licensing negotiation, and assess our potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount can be estimated, we accrue a liability for the estimated loss. Because of uncertainties related to these matters, accruals, if any, are based only on the most current and dependable information available at any given time. As additional information becomes available, we may reassess the potential liability from pending claims and litigation and the probability of claims being successfully asserted against us. As a result, we may revise our estimates related to these pending claims and litigation. Such revisions in the estimates of the potential liabilities could have a material impact on our consolidated results of operations, financial position and cash flows in the future. For further detail, see Note 3 of Notes to Consolidated Financial Statements.

Impact of Recently Issued Accounting Standards

In February 2013, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2013-02, Topic 350 - Comprehensive Income ("ASU 2013-02"), which amends Topic 220 for the reporting of reclassifications out of accumulated other comprehensive income to the respective line items in net income. ASU 2013-02 is effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2012. We intend to adopt this standard in the first quarter of 2014 and do not expect the adoption will have a material impact on our consolidated results of operations or financial condition.

In July 2013, the FASB issued ASU No. 2013-11, Topic 740 - Income Taxes ("ASU 2013-11"), which provides guidance to the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. We intend to adopt this standard in the first quarter of fiscal 2015 and do not expect the adoption will have an impact on our consolidated financial statements.

Liquidity and Capital Resources

The following summarizes information regarding our cash, investments, and working capital (in thousands):

Cash and cash equivalents increased by $41.2 million primarily due to cash provided by operating activities of $32.2 million , cash provided by investing activities of $16.5 million offset by cash used in financing activities of $7.4 million . Refer to further discussions below under Key Components of Cash Flows and Liquidity .

Short-term investments increased by $19.7 million and Long Term Marketable Securities decreased by $8.8 million. The primary increase in Cash and Cash Equivalents is attributable to the $42.7 million sale of our Santa Clara campus. The changes among our Short Term Investments and Marketable Securities was the result of our efforts to manage our various investments so as to fund operations and share repurchases. Refer to further discussions below under Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

The increase in working capital of $23.9 million was primarily due to higher cash and cash equivalents and short term investments offset by higher accounts payables and decrease in the assets held for sale classified as current assets.

Key Components of Cash Flows and Liquidity

A summary of the sources and uses of cash and cash equivalents is as follows (in thousands):

Cash and cash equivalents, short-term investments and marketable securities were $205.6 million at June 30, 2013 , representing an increase of $52.1 million from $153.5 million at June 30, 2012 . This increase was primarily due to cash provided by operations of $32.2 million and cash provided by investing activities of $16.5 million offset by cash used in financing activities of $7.4 million and foreign currency impact of 0.1 million .

Cash provided by operating activities was $32.2 million , an increase of $18.4 million compared to cash provided by operating activities of $13.8 million in fiscal 2012 . Accounts receivable, net, increased to $47.6 million at June 30, 2013 from $41.2 million at June 30, 2012 . Days sales outstanding in receivables increased to 54 days at June 30, 2013 from 42 days at June 30, 2012 . The increase in accounts receivable and days sales outstanding were primarily due to increased billings during the fourth quarter of 2013 resulting in a higher receivables balance. Inventories decreased to $16.2 million at June 30, 2013 from $26.6 million at June 30, 2012 due to the timing of inventory receipts because of which we had lower inventory on hand. Accounts payable increased to $27.2 million at June 30, 2013 from $19.4 million at June 30, 2012 due to timing of payments.

Deferred revenue, net increased to $41.5 million at June 30, 2013 from $39.3 million at June 30, 2012 . This increase was a result of higher sales of service maintenance agreements.

Cash flow provided by investing activities was $16.5 million . Proceeds of $42.7 million from the sale of buildings and land in Santa Clara, California, proceeds from maturities of investments and marketable securities of $16.4 million and sales of investments and marketable securities of $28.5 million were offset by capital expenditures of $12.7 million and purchases of investments of $57.7 million .

Cash flow used in financing activities was $2.4 million resulting from $14.5 million used to repurchase shares of our common stock, offset by $7.1 million of proceeds from the exercise of stock options and purchases of shares of our common stock under the ESPP, net of taxes paid on vested and released stock awards.

Contractual Obligations

The following summarizes our contractual obligations at June 30, 2013 , and the effect such obligations are expected to have on our liquidity and cash flow in future periods (in thousands):

Non-cancelable inventory purchase commitments represent the purchase of long lead-time component inventory that our contract manufacturers procure in accordance with our forecast. Inventory purchase commitments were $50.1 million as of June 30, 2013 , an increase of $11.3 million from $38.8 million as of June 30, 2012 .

Non-cancelable operating lease obligations represent base rents and operating expense obligations to landlords for facilities we occupy at various locations.

The amounts in the table above exclude $0.3 million of income tax liabilities related to uncertain tax positions as we are unable to reasonably estimate the timing of settlement.

We did not have any material commitments for capital expenditures as of June 30, 2013 . Other non-cancelable purchase commitments represent OEM and technology agreements.

Off-Balance Sheet Arrangements

We did not have any off-balance sheet arrangements as of June 30, 2013 .

Capital Resources and Financial Condition

As of June 30, 2013 , in addition to $95.8 million in cash and cash equivalents, we had $43.0 million invested in short-term investments and $66.8 million invested in long-term marketable investments for total cash and cash equivalents, short-term investments and marketable securities of $205.6 million .

We believe that our current cash and cash equivalents, short-term investments, marketable securities and cash available from future operations will enable us to meet our working capital requirements for at least the next 12 months.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Sensitivity

The primary objective of our investment activities is to preserve principal while at the same time maximize the income we receive from our investments without significantly increasing risk. Some of the securities that we have invested in may be subject to market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to fluctuate. For example, if we hold a security that was issued with a fixed interest rate at the then-prevailing rate and the prevailing interest rate later rises, the principal amount of our investment will probably decline. To minimize this risk, we maintain our portfolio of cash equivalents and short-term investments in a variety of securities, including commercial paper, other non-government debt securities and money market funds.

The valuation of our investment portfolio is subject to uncertainties that are difficult to predict. Factors that may impact its valuation include changes to credit ratings of the securities, discount rates and ongoing strength and quality of market credit and liquidity.

If the current market conditions deteriorate further, or the anticipated recovery in market values does not occur, we may be required to record impairment charges in future quarters.

The following table presents the amounts of our cash equivalents, short-term investments and marketable securities that are subject to market risk by range of expected maturity and weighted-average interest rates as of June 30, 2013 and June 30, 2012 . This table does not include money market funds because those funds are generally not subject to market risk.

The following tables present hypothetical changes in fair value of the financial instruments held at June 30, 2013 that are sensitive to changes in interest rates:
