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 wired and wireless network infrastructure equipment, software and services for enterprises, data centers, and service providers. Our customers include businesses, hospitals, hotels, universities, sports venues, telecommunications companies and government agencies around the world. We are driven by our guiding principles to build the very best products, to deliver world-class customer service and to be the easiest company with which to do business. 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 simple, fast and smart networking solutions to deliver better connections, providing superior experiences for everyone. 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.

During the fourth quarter of fiscal 2015 , we implemented a plan to reduce costs through targeted restructuring activities intended to reduce operating costs and realign our organization in the current competitive environment. We initiated a plan to reduce our worldwide headcount by more than 225 employees, consolidate specific global administrative functions, and shift certain operating costs to lower cost regions, among other actions.

On October 31, 2013 , we completed the acquisition of Enterasys Networks, Inc. ("Enterasys"), a privately held provider of wired and wireless network infrastructure and security solutions, whereby Enterasys became our wholly-owned subsidiary. The combined entity immediately became a networking industry leader with more than 14,000 customers. As network switching leaders in enterprise, data center and cloud, Extreme and Enterasys together combine and extend their world-class products and technologies to provide customers with some of the most advanced, high performance, and open solutions in the market as well as a superb overall customer experience. The combination of Extreme and Enterasys is significant in that it brings together two companies with distinct strengths addressing the key areas of the network, from unified wired and wireless edge, to the enterprise core, to the data center and cloud. With an open software approach, we can drive product innovations and customers will benefit from the increased resources and larger scale.

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 a common technology across both enterprises and service providers. Extreme Networks' strategy, product portfolio, and research and development are aligned with the following trends:

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 fixed world to a new world of mobility where everything - people, devices, machines, and applications - is 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, tablets and their applications, and as they work on-the-go. Users know what they need to be productive, and they expect the network to help them achieve productivity. The blurring of work and personal applications that must be supported on the network places increasing security and management demands on IT.

Extreme Networks delivers mission critical software and services led networking solutions designed for the BYOD world, spanning high-performance data centers, the campus, and the mobile infrastructure. Customers deploying our solutions 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 solutions help enable granular visibility and control, higher performance and resource security.

Our strategy is to offer differentiated software and services led networking solutions that deliver a stronger value proposition to our customers and offer 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:

Data can now be mined to show how applications are being used; enabling a better understanding of customer behavior on the network, identifying the level of user engagement, and assuring business application delivery to optimize the user experience. Additionally application adoption can be tracked to determine the return on investment associated with new application deployments.

In addition visibility into network and application performance enables IT to pinpoint and resolve performance bottlenecks in the infrastructure whether they are caused by the network, application, or server. This saves both time and money for the business and ensures critical applications are running at the best possible performance.

The value of SDN in the enterprise lies specifically in the ability to provide network virtualization and automation of configuration across the entire network/fabric so new services and end systems can be deployed rapidly and operational cost can be minimized.

Products

Our products offer resilient high performance networking, intelligence and operational simplicity for IT.  We build our products into vertical markets solutions for converged campus networks with user and device mobility, data center and cloud administrators to virtualize their server and storage over a high-performance Ethernet infrastructure, service providers to provide bandwidth and service level agreements for Carrier Ethernet, 3G and 4G services, and management software that provide visibility, security and intelligent control - all through a single pane of glass.

wireless hardware to deliver standards-based control of other vendors' network equipment. This means faster provisioning, quicker problem resolution, tighter security and reduced IT administration time.

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, wireless and software analytics 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.

Alliance, Original Equipment Manufacturers ("OEM") and Strategic Relationships. We have active Alliance, OEM & Strategic relationships with Barco NV, Ericsson Enterprise AB, SGI, PC HK Ltd., Nokia Siemens Networks, and Aviat Networks, Inc. as well as other global industry technology leaders in which our products are qualified to be included into an overall solution or reference architectures.  These tested and validated solutions are then marketed and sold by the Alliance, OEM or Strategic partner into their specific verticals, market segments and customers as turnkey offerings.   

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. Distributor, Westcon Group, Inc., accounted for 15% , 11% and 16% of our net revenue in fiscal years 2015 , 2014 and 2013 , respectively. Distributor, Tech Data Corporation, accounted for 15% , 11% and 10% of our net revenue in fiscal years 2015 , 2014 and 2013 , respectively. Each of Westcon Group and Tech Data Corporation entered into agreements on substantially the same material terms as we generally enter into with each of our distributor partners. 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, 2015 , our worldwide sales and marketing organization consisted of approximately 496 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 29 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 2015 , sales to customers outside of the United States accounted for 57% of our consolidated net revenue, compared to 59% in fiscal 2014 and 66% in fiscal 2013 . 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, our resellers and our technology alliance partners. Our marketing efforts include participation in industry tradeshows, conferences and seminars, publication of technical and educational articles in industry journals, communication across social media channels, 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, 2015 , net of anticipated back end rebates for distributor sales, was $14.8 million, compared with product backlog of $10.7 million at June 30, 2014 .

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:

individualized network strategies. These activities may include the management and coordination of the design and network configuration, resource planning, staging, logistics, migration and deployment. We also provide customized training and operational best practices manuals to assist customers in the transition and sustenance of their networks.

Long-Lived Assets

See Note 3 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, Salem, New Hampshire, Toronto, Canada 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 manufacture our Summit, A-Series, B-Series, C-Series, Stackable products, G-Series, D-Series, I-Series and 800-Series Standalone products and Black Diamond Chassis products. Alpha Networks is a global networking Original/Joint Design Manufacturer ("ODM/JDM") leader with core competencies in areas such as Ethernet, LAN/MAN, Wireless, Broadband and VoIP. Alpha Networks manufacturing processes and procedures are ISO 9001 certified.

We use Benchmark Electronics, Inc. ("Benchmark") headquartered in Huntsville, Alabama and Flextronics Int'l ("Flextronics") headquartered in Singapore, to manufacture our S-Series and K-Series Chassis products; 7100-Series Stackable products and SSA Standalone products. Benchmark and Flextronics have a significant investment in capital to ensure they have the latest in manufacturing and test technologies and both companies are ISO 9001 certified.

Our wireless Access Point products are supplied by Senao Electronics ("Senao"), headquartered in Taipei, Taiwan. Senao's manufacturing processes and procedures are ISO 9001 certified.

All of our 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 a collaborative sales and operations planning 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 ODM/JDM, OEMs and CMs. Purchase commitments with our manufacturers ODM/JDM, CMs and OEMs 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 modular operating systems 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, 2015 , our research and development organization consisted of 389 employees. Research and development efforts are conducted in several locations, including San Jose, California; RTP, North Carolina; Salem, New Hampshire, Toronto, Canada and Chennai, India. Our research and development expenses in fiscal years 2015 , 2014 and 2013 were $93.4 million , $77.1 million and $40.5 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, 2015 , we have 347 issued patents in the United States and 183 patents outside of the United States. The expiration dates of our issued patents in the United States range from 2016 to approximately 2032. Although we have patent applications pending, there can be no assurance that patents will be issued from pending applications or t hat 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, inventions assignment or license agreements with our employees, consultants and other third parties with whom we do business, 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" or "click-through" 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, routers and software (including analytics) 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 this 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., Dell, Hewlett-Packard Company, Huawei Technologies Co. Ltd., 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. We are also subject to regulatory developments, including recent SEC disclosure regulations relating to so-called "conflict minerals," relating to ethically responsible sourcing of the components and materials used in our products. 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. 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, 2015 , we employed 1,351 people, including 496 in sales and marketing, 389 in research and development, 184 in operations, 189 in customer support and service, and 93 in finance and administration. We have never had a work stoppage and no U.S. employees 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 employees, and upon the continued service of our senior management and key employees. 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 highly competitive.

Organization

We were incorporated in California in May 1996, and reincorporated in Delaware in March 1999. Our corporate headquarters are located at 145 Rio Robles, San Jose, CA 95134 and our telephone number is (408) 579-2800.

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 may fail to realize the anticipated benefits of the acquisition of Enterasys.

The success of the acquisition of Enterasys Networks Inc., which we acquired on October 31, 2013 , will depend on, among other things, our ability to combine the businesses of Extreme and Enterasys in a manner that does not materially disrupt existing relationships and that allows us to achieve anticipated operational synergies. We have faced and will continue to face significant challenges in combining the two operations into one in a timely and efficient manner. The failure to integrate successfully and to manage successfully the challenges presented by the integration process may result in us not achieving the anticipated benefits of the acquisition.

We have made certain assumptions relating to the acquisition in our forecasts but the actual results could differ materially.

We have made certain assumptions relating to the forecast level of cost savings, synergies and associated costs of the acquisition of Enterasys. Our assumptions relating to the forecast level of cost savings, synergies and associated costs of the acquisition may be inaccurate based on the information available to us, including as the result of the failure to realize the expected benefits of the acquisition, higher than expected transaction and integration costs, including our ability to service new debt, as well as general economic and business conditions that may adversely affect the combined company following the completion of the acquisition.

The global 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.

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:

Substantially 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.

The combination of our business with the Enterasys' business will continue to require significant management attention, and we expect to incur additional costs due to integration.

The combined company requires us to devote significant management attention and other resources to integrating the two businesses. We may not successfully complete the integration of our operations in a timely manner and may experience disruptions in relationships with customers, suppliers and employees as a result.

Through June 30, 2015 , we have incurred transaction and integration costs in connection with the Enterasys acquisition of $35.9 million . We expect to incur additional costs integrating the companies' operations, product offerings, and personnel, which cannot be estimated accurately at this time. Although we expect that the realization of efficiencies related to the integration of the business will offset incremental transaction, integration and restructuring costs over time, we cannot give any assurance that this net benefit will be achieved. If the total costs of the integration exceed the anticipated benefits of the acquisition, our results of operations could be adversely affected.

We expect the average selling prices of our products to decrease, which is likely to 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.

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

Our credit facilities impose financial and operating restrictions on us.

Our debt instruments impose, and the terms of any future debt may impose, operating and other restrictions on us. These restrictions could affect, and in many respects limit or prohibit, among other items, our ability to:

The agreements governing our credit facilities also require us to achieve and maintain compliance with specified financial ratios.

A breach of any of these restrictive covenants or the inability to comply with the required financial ratios could result in a default under our debt instruments. If any such default occurs, the lenders under our credit agreement may elect to declare all outstanding borrowings, together with accrued interest and other fees, to be immediately due and payable. The lenders under our credit agreement also have the right in these circumstances to terminate any commitments they have to provide further borrowings. If we are unable to repay outstanding borrowings when due, the lenders under our credit agreement will have the right to proceed against the collateral granted to them to secure the debt. If the debt under our credit agreement were to be accelerated, we cannot give assurance that this collateral would be sufficient to repay our debt.

If we fail to meet our payment or other obligations under our credit agreement, the lenders under such credit agreement could foreclose on, and acquire control of, substantially all of our assets.

Our credit agreement is jointly and severally guaranteed by us and certain of our subsidiaries. Borrowings under our credit facilities are secured by liens on substantially all our assets, including the capital stock of certain of our subsidiaries, and the assets of our subsidiaries that are loan party guarantors. If we are unable to repay outstanding borrowings when due, the lenders under our credit agreement will have the right to proceed against this pledged capital stock and take control of substantially all of our assets.

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 attaining 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 Technologies Co. Ltd., 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. Some of our customers may question whether we have the financial resources to complete their projects and future service commitments.

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 gross margins will be adversely affected.

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

We have undertaken restructuring efforts in the past 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.

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.

If we do not successfully anticipate technological shifts, market needs and opportunities, and develop products and product enhancements that meet those technological shifts, needs and opportunities, or if those products are not made available in a timely manner or do not gain market acceptance, we may not be able to compete effectively and our ability to generate revenues will suffer.

 We cannot guarantee that we will be able to anticipate future technological shifts, market needs and opportunities or be able to develop new products or product enhancements to meet such technological shifts, needs or opportunities in a timely manner or at all. For example, the move from traditional network infrastructures towards SDN has been receiving considerable attention. In our view, it will take several years to see the full impact of SDN, and we believe the successful products and solutions in this market will combine hardware and software elements together. If we fail to anticipate market requirements or fail to develop and introduce new products or product enhancements to meet those needs in a timely manner, it could cause us to lose customers, and such failure could substantially decrease or delay market acceptance and sales of our present and future products, which would significantly harm our business, financial condition, and results of operations. Even if we are able to anticipate, develop, and commercially introduce new products and enhancements, there can be no assurance that new products or enhancements will achieve widespread market acceptance.

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, the lack of predictability of such awards, and the high legal costs associated with the defense of such patent infringement matters that would be expended to prove lack of infringement, 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 under certain circumstances. 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 defense of legal claims, 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 other 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 adequate insurance coverage to 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, invention assignment or license agreements with our employees, consultants and other third parties with whom we do business, 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 inter-operate 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 a few manufacturers for our manufacturing requirements could harm our operating results.

We primarily rely on our manufacturing partners; Alpha Networks, Inc. headquartered in Hsinchu, Taiwan, Flextronics, Inc. headquartered in Singapore, and select other partners to manufacture our products. We have experienced delays in product shipments from our manufacturing partners 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 partners could significantly disrupt our business. While we maintain strong relationships with our manufacturing partners, our agreements with these manufacturers 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 partners 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 manufacturers.

As part of our cost-reduction efforts, we will need to realize lower per unit product costs from our manufacturing partners 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 operating results.

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:

Our revenues may decline as a result of changes in public funding of educational institutions.

 A portion of our revenues comes from sales to both public and private K-12 educational institutions. Public schools receive funding from local tax revenue, and from state and federal governments through a variety of programs, many of which seek to assist schools located in underprivileged or rural areas. The funding for a portion of our sales to educational institutions comes from a federal funding program known as the E-Rate program. E-Rate is a program of the Federal Communications Commission that subsidizes the purchase of approved telecommunications, Internet access, and internal connection costs for eligible public educational institutions.  The E-Rate program, its eligibility criteria, the timing and specific amount of federal funding actually available and which Wi-Fi infrastructure and product sectors will benefit, are uncertain and subject to final federal program approval

and funding appropriation continues to be under review by the Federal Communications Commission and there can be no assurance that this program or its equivalent will continue, and as a result, our business may be harmed. Furthermore, if state or local funding of public education is significantly reduced because of legislative or policy changes or by reductions in tax revenues due to changing economic conditions, our sales to educational institutions may be negatively impacted by these changed conditions. Any reduction in spending on information technology systems by educational institutions would likely materially and adversely affect our business and results of operations. This is a specific example of the many factors which add additional uncertainty to our future revenue from our education end-customers.

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 above 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 and train 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.

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. We need to ensure that the businesses acquired are appropriately integrated in our financial systems. We integrated the financial and other key managerial systems of Enterasys with Extreme effective July 1, 2014, the first day of our fiscal 2015. Any delay in the implementation of, or disruption in the integration of acquired businesses, or delay and 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.

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 restructuring. 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 May 31, 2016, subject to ratification by a majority of stockholders at our next annual stockholder meeting expected to be held on November 12, 2015 .

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 Stock Market 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, which investments may have a material impact on the Company's financial condition.

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 centers in North Carolina and New Hampshire have 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, including open source software, 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.  Further, the failure to comply with the terms of any license, including free open source software, may result in our inability to continue to use such license. Our inability to maintain or re-license any third-party licenses required in our products or our inability to obtain third-party licenses necessary to develop new products and product enhancements, could require us, if possible, to develop substitute technology or obtain substitute technology of lower quality or performance standards or at a greater cost, any of which could delay or prevent product shipment and harm our business, financial condition, and results of operations.

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.

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 networking solutions 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 canceled. This could hurt our operating results, damage our reputation, and seriously harm our business and prospects.

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

Business Overview

We believe that understanding the following key developments is helpful to an understanding of our operating results for the fiscal year ended June 30, 2015 .

We are a leading provider of network infrastructure equipment and offer related services contracts for extended warranty and maintenance to our enterprise, data center and service provider customers. We were incorporated in California in May 1996, and reincorporated in Delaware in March 1999. Our corporate headquarters are located in San Jose, California. Substantially all of our revenue is derived from the sale of our networking equipment and related service contracts.

On June 26, 2015, the Senior Secured Credit Facilities were amended and reduced to $115 million from $125 million, with the Revolving Facility being reduced to $50 million from $60 million. The Senior Secured Credit Facilities, as amended, mature on October 31, 2018. 

During the fourth quarter of fiscal 2015, we implemented a plan to reduce costs through targeted restructuring activities intended to reduce operating costs and realign our organization in the current competitive environment. We initiated a plan to reduce our worldwide headcount by more than 225 employees, primarily in sales and marketing as well as research and development, consolidate specific global administrative functions, and shift certain operating costs to lower cost regions, among other actions. We expect to reduce our operating expenses by approximately $40 million on an annualized basis due to these actions.

On October 31, 2013, we completed the acquisition of Enterasys, a privately held provider of wired and wireless network infrastructure and security solutions, for $180.0 million, net of cash acquired, whereby Enterasys became our wholly-owned subsidiary. The combined entity immediately became a networking industry leader with more than 14,000 customers. As a combined Company, we believe we will set the standard for the networking industry with a strategic focus on three principles:

Impact of the Global Economic Developments

We believe that the slow economic recovery in the United States, Asia 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 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, consolidation of office locations, 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. New software and hardware introductions during the current year included a Summit X770 switch supporting industry's highest density performing top of rack switching, Purview - a network-powered application analytics and optimization solution, identiFi 38xx WiFi Access Points supporting 802.11ac, SDN 2.0 - an open, standards-based (based on OpenDaylight) and comprehensive SDN solution, 100GbE support for the BDX8 and NetSight 6.0 a consolidated management across the expanded portfolio. During fiscal 2014, we also introduced key software functionality that will drive differentiation.  Over the past few years, we further extended our product portfolio through the Summit family of stackable switches for the intelligent edge, continued evolutions of our BlackDiamond BDX8, a highly-scalable core switch for IT and cloud data centers, the S-series flow-based switching for campus and data center, the identiFi Wi-Fi product portfolio with both indoor and outdoor 802.11a/b/g/n/ac access points, the E4G Cell Site Router family for mobile backhaul, and a revamp of our software and network management solutions that include: NetSight for centralized network management and NAC/Mobile-IAM that provides BYOD management and network access control solution for wired and wireless LAN and VPN users.​

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 acquisition of Enterasys gives us a larger market share and presence and an opportunity to create complementary solutions for our 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 per port. 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 the Company 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 our Series A Preferred Stock. 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 us and Mellon Investor Services LLC (the "Prior Rights Plan").

The Board reviewed the necessity of the provisions of the Prior Rights Plan. The Prior Rights Plan was adopted to preserve the value of our deferred tax assets, including our net operating loss carry forwards, with respect to our ability to fully use its tax benefits to offset future income which may be limited if we experience an "ownership change" for purposes of Section 382 of the Internal Revenue Code of 1986 as a result of ordinary buying and selling of our common stock. Following its review, the Board decided it was necessary and in the best interests of us and our 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, 2013. 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. The Board of Directors unanimously approved an amendment to the Rights Plan effective May 14, 2015 to extend the Rights Plan through May 31, 2016, subject to ratification by a majority of the stockholders at the next annual meeting, expected to be held on November 12, 2015 .

Results of Operations

Our operations and financial performance have been affected by the economic factors described above and our acquisition of Enterasys, and during fiscal 2015 , we achieved the following results:

Net Revenue

Product revenue increased in fiscal 2014 as compared to fiscal 2013 primarily due to significant increase in the number of customers and products sold due to our acquisition of Enterasys in the second quarter of fiscal 2014. This resulted in a significant increase in our product revenue in all regions.

Service revenue increased $27.1 million or 25.1% for the year-ended June 30, 2015 compared to the corresponding period of fiscal 2014 due to an increase in service maintenance contracts and professional service and training revenues due to our acquisition of Enterasys. Purchase accounting charges related to deferred service revenues decreased $2.2 million for the year-ended June 30, 2015 , to $3.1 million from $5.3 million in the corresponding period of fiscal 2014 .

Service revenue increased in fiscal 2014 as compared to fiscal 2013 primarily due to an increase in service maintenance contracts and professional service and training revenues due to our acquisition of Enterasys in the second quarter of fiscal 2014.

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. The following table presents the total net revenue geographically for the fiscal years 2015 , 2014 and 2013 (dollars in thousands):

We rely upon multiple channels of distribution, including distributors, direct resellers, OEM, and direct sales.  Revenue through our distributor channel was 47% of total product revenue in fiscal 2015 , 44% of total product revenue in fiscal 2014 and 43% of total product revenue in fiscal 2013 .

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 2015 , 2014 and 2013 (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, amortization of developed technology intangibles, 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, Salem, New Hampshire, China, and Taiwan.

Product gross profit decreased to $193.0 million for the year-ended June 30, 2015 , from $198.1 million in the corresponding period of fiscal 2014 . Product gross profit for the year-ended June 30, 2015 , was favorably impacted by an increase in product revenue of $6.3 million , offset by higher material costs and increases of $5.8 million in excess and obsolete inventory charges, $6.1 million for amortization of the developed technology intangibles from the acquisition of Enterasys, $3.4 million for distribution costs due to higher utilization of air freight and $3.3 million of warranty charges. Gross profit for fiscal 2014 , was negatively

impacted by $11.1 million related to the sale of inventory which had been adjusted to fair value upon the Enterasys acquisition due to purchase accounting.

Product gross profit increased for fiscal 2014 to $198.1 million as compared to $124.1 million primarily due to significant increase in product revenues due to our acquisition of Enterasys in the second quarter of fiscal 2014 . However, product gross margin in fiscal 2014 decreased as compared to fiscal 2013 primarily due to a $11.1 million charge related to the utilization of the net increase in cost basis of the inventory acquired in connection with the purchase of Enterasys, $11.0 million for the amortization of developed technology intangibles from the acquisition of Enterasys during the second quarter of fiscal 2014 and increased stock compensation expenses offset by higher economic benefits realized in our manufacturing costs as compared to fiscal 2013 .

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

Service gross profit increased to $86.7 million for the year-ended June 30, 2015 , from $69.2 million in the corresponding period of fiscal 2014 , primarily due to increase in service revenue of $27.1 million partially offset by increased personnel, overhead and travel costs as a result of the acquisition of Enterasys. Additionally, purchase accounting charges related to deferred service revenues decreased $2.2 million in fiscal 2015 to $3.1 million from $5.3 million as compared to fiscal 2014 .

Service gross profit in fiscal 2014 increased as compared to fiscal 2013 primarily due to increased service revenue as a result of acquisition of Enterasys and cost reduction initiatives offset by higher personnel, overhead and travel cost as a result of our acquisition of Enterasys during the second quarter of fiscal 2014 .

Operating Expenses

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

The following table highlights our operating expenses and operating income (loss) 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 increased by $16.3 million or 21.1% for fiscal 2015 as compared to fiscal 2014 . The increase in research and development expenses were primarily due to increased spending as a result of our acquisition of Enterasys. The increase in spending related to $13.4 million of personnel costs, which includes compensation, benefits and non-cash stock based compensation, including $0.4 million of expense related to our executive transition activity, $1.3 million in depreciation and $0.8 million for supplies and equipment.

Research and development expenses increased in fiscal 2014 as compared to fiscal 2013 primarily due to increased personnel and occupancy costs as a result of our acquisition of Enterasys in the second quarter of fiscal 2014 .

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 increased by $12.6 million or 8.1% for the year-ended June 30, 2015 as compared to the corresponding period of fiscal 2014 . The increase in sales and marketing expenses during fiscal 2015 was primarily due to $6.7 million of higher compensation, benefits and non-cash stock compensation, including $0.5 million of expense related to our executive transition

activity, $2.7 million in marketing expense, $1.8 million in facilities and $0.8 million in depreciation. All of these factors were primarily driven by the acquisition of Enterasys.

Sales and marketing expenses increased in fiscal 2014 as compared to fiscal 2013 primarily due to increased personnel costs as well as additional spending on additional sales and marketing programs, as a result of our acquisition of Enterasys in the second quarter of fiscal 2014 .

General and Administrative Expenses

General and administrative expense consists primarily of personnel costs, legal and professional service costs, share-based compensation, travel and facilities and information technology costs.

General and administrative expenses increased by $1.2 million or 2.9% for the year-ended June 30, 2015 as compared to the corresponding period of fiscal 2014. The increase in general and administrative expenses was primarily due to $1.1 million in higher personnel costs related to our executive transition activity, higher occupancy costs due to additional facilities in Salem, New Hampshire and Shannon, Ireland as a result of our acquisition of Enterasys, a $0.8 million increase in bad debt expense and $0.2 million in professional service fees. This increase was partial offset by $1.0 million in lower travel costs.

General and administrative expenses increased in fiscal 2014 as compared to fiscal 2013 primarily due to higher personnel and travel costs and higher occupancy costs as a result of our acquisition of Enterasys in the second quarter of fiscal 2014.

Acquisition and Integration Costs

As a result of our acquisition of Enterasys, we incurred $10.2 million and $25.7 million of acquisition and integration costs in fiscal 2015 and 2014 , respectively. For fiscal 2015 , the entire $10.2 million of expense was related to integration costs. The fiscal 2014 expense was related to $19.7 million of integration costs and the remaining $6.0 million expense was related to acquisition costs. The lower fiscal 2015 integration expenses was due to lower severance and termination costs and third party consulting fees. The Company expects to incur integration costs at a considerable lower rate for fiscal 2016.

Amortization of Intangibles

During fiscal 2015 and 2014 , we recorded $17.9 million and $16.7 million, respectively, of amortization expenses primarily for certain intangibles related to the acquisition of Enterasys.

Restructuring Charge, Net of Reversal

During fiscal 2015 , 2014 and 2013 , we recorded restructuring charges, net of reversals, of $9.8 million , $0.5 million and $6.8 million , respectively.

Fiscal 2015 Restructuring

During the fourth quarter of fiscal 2015 , we implemented a plan to reduce costs through targeted restructuring activities intended to reduce operating costs and realign our organization in the current competitive environment. We initiated a plan to reduce our worldwide headcount by more than 225 employees, primarily in sales and marketing as well as research and development, consolidate specific global administrative functions, and shift certain operating costs to lower cost regions, among other actions. We have expensed all costs associated with this initiative. We expect to achieve approximately $40.0 million in operational savings on an annualized basis, beginning in the first quarter of fiscal 2016. As of June 30, 2015 , we anticipate paying the remaining restructuring liabilities of $5.9 million related to the fiscal 2015 restructuring by the end of the second quarter of fiscal 2016. The restructuring liability is recorded in "Other accrued liabilities" on the consolidated balance sheet.

Fiscal 2013 Restructuring

During the second quarter of fiscal 2013 , we 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 of fiscal 2013, 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. We have substantially expensed all costs associated with this initiative. As of June 30, 2015 , there were no outstanding liabilities related to the fiscal 2013 restructuring.

Litigation Settlement (Income) Expense

During fiscal 2014 , the Company received $0.1 million from the settlement of a property lease litigation matter.

During fiscal 2013 , we recognized a litigation charge of $2.5 million related to a settlement agreement entered into with Enterasys prior to the acquisition.

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 $44.7 million of which, $2.0 million was received in fiscal 2012. We realized a gain of $11.5 million in connection with this transaction, yet recorded a tax loss of $24.6 million.

Interest Income

Interest income was $0.5 million , $0.8 million and $1.1 million in fiscal years 2015 , 2014 and 2013 , respectively, representing a decrease of $0.2 million in fiscal 2015 from fiscal 2014 and a decrease of $0.3 million in fiscal 2014 from fiscal 2013 . The decrease in interest income in fiscal 2015 was due to a decrease in the investment balance to fund debt reduction. The decrease in interest income in fiscal 2014 was due to a decrease in our investment portfolio to fund a portion of the acquisition.

Interest Expense

We had $3.2 million and $2.1 million of interest expense for fiscal 2015 and 2014 , respectively. Interest expense was immaterial for fiscal 2013 . Interest expense in fiscal years 2015 and 2014 was primarily related to the Credit Facility that the Company entered into on October 31, 2013 to fund the acquisition of Enterasys.

Other (Expense) Income, net

Other (expense) income net was expense of $1.2 million , $1.6 million and $0.6 million in fiscal years 2015 , 2014 and 2013 , respectively. Other expense in all periods was primarily due to the revaluation of certain assets and liabilities denominated in foreign currencies into U.S. Dollars.

Provision for Income Taxes

We are subject to income taxes in the United States and numerous foreign jurisdictions. Our effective tax rate differs from the U.S. federal statutory rate of 35% primarily due to the impact of state taxes, foreign operations which are generally taxed at lower statutory rates and the full valuation of our deferred tax assets in the U.S. and certain foreign jurisdictions. For the fiscal years ended June 30, 2015 , 2014 and 2013 , we recorded income tax provisions of $4.8 million , $4.2 million and $1.7 million, respectively. The effective tax rates for fiscal years ended June 30, 2015 , 2014 and 2013 were 7.2%, 7.9% and 14.8%, respectively.

For the fiscal years ended June 30, 2015 , 2014 and 2013 the majority of our tax provision relates to taxes on our foreign operations as well as state taxes due to the full valuation allowance on our U.S. and certain foreign deferred tax assets. In the fiscal year ended June 30, 2014, a portion of our provision resulted from the establishment of a U.S. deferred tax liability for amortizable goodwill resulting from the acquisition of Enterasys.

For a full reconciliation of our effective tax rate to the U.S. federal statutory rate of 35% and for further explanation of our provision for income taxes, see Note 9 to the consolidated financial statements.

Critical Accounting Policies and Estimates

Our significant accounting policies are more fully described in Note 3 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.

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. 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 ("VSOE") of selling price, 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 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 $6.1 million and $4.1 million as of June 30, 2015 and 2014 , respectively. Our total deferred revenue for services, primarily from service contracts, was $87.4 million and $89.7 million as of June 30, 2015 and 2014 , respectively. 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 $1.1 million and $2.7 million as of June 30, 2015 and 2014 , 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.

Goodwill

Goodwill is assessed for impairment annually during the fourth quarter of the fiscal year (April 1) or more frequently when an event occurs or circumstances change between annual tests that would more likely than not reduce the fair value of the reporting unit below its carrying value. We have determined that we have one reporting unit. To test goodwill for impairment, we first perform a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is concluded that this is the case, we then perform the two-step goodwill impairment test. Otherwise, the two-step goodwill impairment test is not required. Under the two-step goodwill impairment test, we in the first step, compare the estimated fair value of a reporting unit to its carrying value. If the fair value of the reporting unit exceeds the carrying value, no impairment loss is recognized. However, if the carrying value of the reporting unit exceeds its fair value, the goodwill of the unit may be impaired. The amount, if any, of the impairment is then measured in the second step in which we determine the implied value of goodwill based on the allocation of the estimated fair value determined in the initial step to all assets and liabilities of the reporting unit.

We completed our annual goodwill impairment test in the fourth quarter of fiscal 2015 and determined there was no impairment as the fair value of the reporting unit exceeded its carrying value.

Share-based Payments

We use the Black-Scholes option-pricing model to determine the fair value of option grants other than option grants, with market, performance or service conditions or a combination of those conditions, options assumed as part of the Enterasys acquisition, 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 option grants, with market, performance or service conditions or combinations of those 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 2015 , our estimated forfeiture rates based on historical forfeiture experiences are 14% for executives and 12% for non-executive employees. We use the straight-line method for expense attribution, and we only recognize expense for those shares expected to vest.

Restructuring Charges

The Company recognizes liability for exit and disposal activities when the liability is incurred. A liability for post-employment benefits, including severance, is recorded upon attainment of certain criteria including when payment is probable, the amount is reasonably estimable, and the obligation relates to rights that have vested or accumulated. Facilities consolidation charges are calculated using estimates and are based upon the remaining future lease commitments for vacated facilities from the date of facility consolidation, net of estimated future sublease income. The estimated costs of vacating these leased facilities are based on market information and trend analysis.

The Company continually evaluates the adequacy of the remaining liabilities under its restructuring initiatives. Although the Company believes that these estimates accurately reflect the costs of its restructuring plans, actual results may differ, thereby requiring the Company to record additional provision or reverse a portion of such provision.

Business Combinations 

We allocate the purchase price of acquired companies to the tangible and intangible assets acquired and liabilities assumed, assumed equity awards, as well as to in-process research and development based upon their estimated fair values at the acquisition date. The purchase price allocation process requires management's judgment and often involves the use of significant estimates and assumptions, especially at the acquisition date with respect to intangible assets, deferred revenue obligations and equity assumed.

Although we believe the assumptions and estimates we have made are reasonable and appropriate, they are based in part on historical experience and information obtained from the management of the acquired companies and are inherently uncertain. Examples of critical estimates in valuing certain of intangible assets we have acquired or may acquire in future include but are not limited to assumptions with respect to future cash inflows and outflows, discount rates, intangibles and other asset lives, expected costs to develop the in-process research and development into commercially viable products, among other items.

In connection with the purchase price allocations for our acquisitions, we estimate the fair value of inventory using the comparative sales method. The fair value of the inventory utilizing the comparative sales method is estimated using the selling price, less sales costs, marketing costs and profit on these costs. The operating profit margins are based on the historical margins.

In connection with the purchase price allocations for our acquisitions, we estimate the fair value of deferred revenue using the cost build-up approach. The cost build-up approach determines the fair value by estimating the costs related to fulfilling the obligations plus a normal profit margin. The estimated costs to fulfill the obligations are based on historical costs and benchmarking analysis.

Unanticipated events and circumstances may occur that may affect the accuracy or validity of such assumptions, estimates or actual results. As a result, during the measurement period, which may be up to one year from the acquisition date, we may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our consolidated statements of operations.

Impact of Recently Issued Accounting Standards

In May 2014, the FASB, jointly with the International Accounting Standards Board, issued Accounting Standard Update No. 2014-09 (Topic 606) - Revenue from Contracts with Customers ("ASU 2014-09"). This ASU's core principle is that a reporting entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying this new guidance to contracts within its scope, an entity will: (1) identify the contract(s) with a customer, (2) identify the performance obligation in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies a performance obligation. Additionally, this new guidance will require significantly expanded disclosures about revenue recognition. ASU 2014-09 is effective for annual reporting periods (including interim reporting periods within those annual periods) beginning after December 15, 2016. In July 2015, the FASB approved a one-year deferral of the effective date of the new standard. The new standard will be effective for our fiscal 2019, with early adoption permitted. Entities have the option of using either a full retrospective or a modified retrospective approach to adopt this ASU. We are currently evaluating the potential effect on its consolidated financial statements from adoption of this standard.

In November 2014, the FASB has issued ASU 2014-15, Disclosure of Uncertainties About an Entity's Ability to Continue as a Going Concern , which provides guidance on determining when and how to disclose going-concern uncertainties in the financial statements. The new standard requires management to perform interim and annual assessments of an entity's ability to continue as a going concern within one year of the date of issuance of the entity's financial statements and provide certain disclosures when there is substantial doubt about the entity's ability to continue as a going concern. This guidance applies to all entities and is effective for annual periods beginning after December 15, 2015, and interim periods thereafter, with early adoption permitted. We are currently evaluating the potential effect on its consolidated financial statements from adoption of this standard.

In February 2015, the FASB issued ASU 2015-02 which provides consolidation guidance and changes the way reporting enterprises evaluate consolidation for limited partnerships, investment companies and similar entities, as well as variable interest entities. The ASU is effective for annual and interim periods in fiscal years beginning after December 15, 2015. We do not believe adoption of this standard will have a material impact on our consolidated financial statements.

In April 2015, the FASB issued ASU 2015-03 - Simplifying the Presentation of Debt Issuance Costs, which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. ASU 2015-03 requires retrospective adoption and will be effective for annual and interim periods in fiscal years beginning after December 15, 2015. Early adoption is permitted. We do not believe adoption of this standard will have a material impact on our consolidated financial statements.

In July 2015, the FASB issued ASU 2015-11, which requires entities to measure most inventory "at the lower of cost and net realizable value," thereby simplifying the current guidance under which an entity must measure inventory at the lower of cost or market (market in this context is defined as one of three different measures). The ASU will not apply to inventories that are measured by using either the last-in, first-out ("LIFO") method or the retail inventory method ("RIM"). The ASU is effective prospectively for annual periods beginning after December 15, 2016, and interim periods therein. Early application of the ASU is permitted. Upon transition, entities must disclose the nature of and reason for the accounting change. We do not believe adoption of this standard will have a material impact on our consolidated financial statements.

Recently Adopted Accounting Pronouncements

In July 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2013-11, Income Taxes (Topic 740)- 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"). This ASU provides guidance regarding the presentation in the statement of financial position of an unrecognized tax benefit when a net operating loss carryforward or a tax credit carryforward exists. The ASU generally provides that an entity's unrecognized tax benefit, or a portion of its unrecognized tax benefit, should be presented in its financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 31, 2013. We adopted this standard prospectively in the first quarter of the fiscal year ending June 30, 2015, its adoption did not have a material impact on our consolidated financial statements.

Liquidity and Capital Resources

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

As of  June 30, 2015 , our principal sources of liquidity consisted of cash and cash equivalents of  $76.2 million , accounts receivable, net of  $92.7 million and availability of borrowings from the Revolving Facility of $20.6 million as of  June 30, 2015 . Our principal uses of cash will include repayments of debt and related interest, purchase of finished goods inventory from our contract manufacturers, payroll, restructuring expenses and other operating expenses related to the development, marketing of our products and purchases of property and equipment. We believe that our  $76.2 million  of cash and cash equivalents at  June 30, 2015 , cash flows from operations along with the availability of borrowings from the Revolving Facility will be sufficient to fund our principal uses of cash for at least the next 12 months.

The Senior Secured Credit Facilities, as amended, contain financial covenants that require us to maintain a minimum Consolidated Fixed Charge Coverage Ratio and Consolidated Quick Ratio and a maximum Consolidated Leverage Ratio and several other financial and non-financial covenants and restrictions that limit our ability to incur additional indebtedness, create liens upon any of our property, merge, consolidate or sell all or substantially all of our assets, etc.  

The Senior Secured Credit Facilities, as amended, also include customary events of default, including failure to pay principal, interest or fees when due, failure to comply with covenants, if any representation or warranty made by us is false or misleading in any material respect, certain insolvency or receivership events affecting Extreme and its subsidiaries, the occurrence of certain material judgments, the occurrence of certain ERISA events, the invalidity of the loan documents or a change in control of our Company.  The amounts outstanding under the Senior Secured Credit Facilities, as amended, may be accelerated upon certain events of default. We believe we are in compliance and expect to remain in compliance with the covenants of the Senior Secured Credit Facilities, as amended, and they are not expected to impact our liquidity or capital resources.

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, cash equivalents and short-term investments were $76.2 million at June 30, 2015 , representing a decrease of $29.7 million from $105.9 million at June 30, 2014 . Cash and cash equivalents increased primarily due to cash provided by operations of $37.4 million and cash provided by investing activities of $21.6 million offset by cash used in financing activities of $52.5 million and foreign currency impact of $3.5 million .

Cash provided by operating activities was $37.4 million compared to cash used in operating activities of $26.8 million in fiscal 2014, an increase of $64.3 million during the year ended June 30, 2015. The current year's net loss of $71.6 million was primarily offset by non-cash expenses such as amortization of intangibles, stock-based compensation, and depreciation. Decreases in accounts receivables and increases in deferred revenue were also factors contributing to the cash provided by operating activities for the year ended June 30, 2015.

Cash flow provided by investing activities of $21.6 million , was mainly due to proceeds from sales and maturities of investments of $32.4 million offset by capital expenditures of $7.2 million and purchase of non-marketable equity investments of $3.0 million .

Cash flow used in financing activities was $52.5 million due to the repayment of debt of $78.7 million and borrowings of $24.0 million on the Revolving Facility for working capital requirements.

Contractual Obligations

The following summarizes our contractual obligations at June 30, 2015 , 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 $69.9 million as of June 30, 2015 , an increase of $5.2 million from $64.7 million as of June 30, 2014 .

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

Other liabilities include the Company's commitments towards debt related fees and specific arrangements other than inventory.

The amounts in the table above exclude income tax liabilities related to uncertain tax positions as existing tax attributes of the Company are available to offset any potential income tax obligations.

We did not have any material commitments for capital expenditures as of June 30, 2015 .

Off-Balance Sheet Arrangements

We did not have any off-balance sheet arrangements as of June 30, 2015 .

Capital Resources and Financial Condition

As of June 30, 2015 , we had $76.2 million in cash and cash equivalents. We believe that our current cash, cash equivalents, cash available from future operations along with the availability of borrowings from the Revolving Facility 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, 2014 . This table does not include money market funds as those funds are generally not consider subject to market risk We did not have any short-term investments or marketable securities as of June 30, 2015 . (dollars in thousands)
