PART I

Item 1. Business

Aviat Networks, Inc., together with its subsidiaries, is a global supplier of microwave networking solutions, backed by an extensive suite of professional services and support. Aviat Networks, Inc. may be referred to as "the Company," "AVNW," "Aviat Networks," "we," "us" and "our" in this Annual Report on Form 10-K.

We were incorporated in Delaware in 2006 to combine the businesses of Harris Corporation's Microwave Communications Division ("MCD") and Stratex Networks, Inc. ("Stratex"). On January 28, 2010, we changed our corporate name from Harris Stratex Networks, Inc. to Aviat Networks, Inc.

Our principal executive offices are located at 5200 Great America Parkway, Santa Clara, California 95054, and our telephone number is (408) 567-7000. Our common stock is listed on the NASDAQ Global Select Market under the symbol AVNW. As of July 1, 2016 , we employed approximately 720 people, compared with approximately 780 people as of July 3, 2015 .

Overview and Description of the Business

We design, manufacture and sell a range of wireless networking products, solutions and services to mobile and fixed public network operators, private network operators, Federal, State and Local government agencies, transportation, energy and utility companies, public safety agencies and broadcast network operators around the world. We sell products and services directly to our customers and also use agents and resellers.

Our products utilize microwave and millimeter wave technologies to create point to point wireless links for short, medium and long distance interconnections. Our products incorporate Ethernet switching and IP routing capabilities to form complete networking solutions. We also provide network management software tools to enable our customers to deploy, monitor and manage our systems; third party equipment such as antennas, routers, optical transmission equipment and other equipment necessary to build and deploy a complete telecommunications transmission network. We provide a full suite of professional services for planning, deployment, operations and maintenance of our customers' networks.

Our wireless systems deliver urban, suburban, regional and country-wide communications links as the primary alternative to fiber optic connections. In dense urban and suburban areas, short range wireless solutions are faster to deploy and lower cost per mile than new fiber deployments. In developing nations, fiber infrastructure is scarce and wireless systems are used for both long and short distance connections. Wireless systems also have advantages over optical fiber in areas with rugged terrain, and to provide connections over bodies of water such as between islands or even oil and gas production platforms.

Revenue from our North America and international regions represented approximately 47% and 53% , respectively, of our revenue in fiscal 2016 , 46% and 54% , respectively, of our revenue in fiscal 2015 , and 41% and 59% , respectively, of our revenue in fiscal 2014 . Information about our revenue attributable to our geographic regions is set forth in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" and in "Note 9. Segment and Geographic Information" of the accompanying consolidated financial statements in this Annual Report on Form 10-K.

Market Overview

We believe that future demand for microwave and millimeter wave transmission systems will be influenced by a number of factors across several market segments.

Mobile Networks

As mobile networks expand, add subscribers and increase the number of wirelessly connected devices, sensors and machines, they require investment in backhaul infrastructure. Whether mobile network operators choose to self-build this backhaul infrastructure or lease backhaul services from other network providers, the evolution of the network drives demand for transmission technologies such as microwave and millimeter wave wireless backhaul. Within this overall scope there are multiple individual drivers for investment in backhaul infrastructure.

video streaming services. The rapid increases in data to be transported through the RAN and across the backhaul infrastructure drives requirements for higher data transport links necessitating upgrades to or replacement of the existing backhaul infrastructure.

Other Vertical Markets

In addition to mobile backhaul, we see demand for microwave technology in other vertical markets, including utility, public safety, financial institutions and broadcast.

financial industry. Our products have already been used to create low latency connections between major centers in the United States ("U.S."), Europe and Asia and we see long-term interest in the creation of further low latency routes in various geographies around the world.

These factors are combining to create a range of opportunities for continued investment in backhaul and transport networks favoring microwave and millimeter wave technologies. As we focus on our execution of the future generations of our technology, our goal is to make wireless a viable choice for an ever broadening range of network types.

Strategy

Over the past year, we continued to invest in our microwave and IP Routing solutions, especially in expanding the software enabled features and functions of our CTR 8000 platform. The CTR is a transformational microwave product line since it efficiently integrates microwave transport and IP routing in a single solution. The software defined functionality of the CTR platform allows us to expand its capability over time and create further revenue generating software releases in the future. This is the first product in the industry to integrate Layer 3 MPLS and Microwave transmission functions in a single solution. We have continued to invest in our Eclipse IRU 600 platform which is targeted for our North America customer base with expansion of our industry leading power output capability across multiple frequency bands. We continue to invest in covering frequency bands to specifically address the needs of Federal Agencies facing the relocation of services from bands subject to Federal Communications Commission auction.

Our longer term technology development roadmap positions us for future network evolution and is crafted to maximize design re-use of critical hardware and software elements.

We continued to develop our professional services portfolio as a key to our long-term strategy and differentiation. During the year, we continued to expand the number of customer networks managed from our North America Network Operations Center. We began offering cloud based network management to select customers and we continue to offer training and accreditation programs for microwave and IP network design, deployment and maintenance.

Our strategy includes partnering with companies with technical expertise in areas outside of our core competencies to meet our customers' demand for an end-to-end solution. Our partner product strategy enables us to go beyond wireless transmission to address the vendor consolidation trend whereby customers are "buying more from fewer vendors" and in doing so providing expanding market share opportunity. A comprehensive solutions portfolio comprised of our wireless product and intelligent partner products can allow us to compete with vendors that offer turnkey solution portfolios and serve to focus our research and development ("R&D") efforts on core competency wireless innovations. Having a broader portfolio will enable us to further differentiate our offerings from other independent microwave equipment suppliers.

We expect to continue to serve and expand upon our existing customer base and develop business with new customers. We have sold more than 1,000,000 microwave radios in over 140 countries and are present in more than 350 mobile networks worldwide. We intend to leverage our customer base, our longstanding presence in many countries, our distribution channels, our comprehensive product line, our superior customer service and our turnkey solution capability to continue to sell existing and new products and services to current and future customers.

Products and Solutions

We offer a comprehensive product and solutions portfolio that meets the needs of service providers and network operators in every region of the world and addresses a broad range of applications, frequencies, capacities and network topologies. Our product categories include point-to-point microwave and millimeter wave radios that are licensed (subject to local frequency regulatory requirements), lightly-licensed and license-exempt (operating in license-exempt frequencies), and element and network management software. In addition, we provide a full suite of professional services enabling us to deliver end-to-end turnkey networks, including complete design, deployment, maintenance, and managed services, while being an attentive and adaptable partner for our customers - a key competitive differentiator for us.

solutions address a wide range of transmission frequencies, ranging from 2.4 GHz to 90 GHz, and a wide range of transmission capacities, ranging up to over 4 Gbps. The major product families included in these solutions are CTR 8000, Eclipse, IRU 600 and ProVision, our network management software including the AviatCloud solution.

Business Operations

Sales and Service

Our primary route to market is through our own direct sales, service and support organization. This provides us with the best opportunity to leverage our role as a technology specialist and differentiate ourselves from competitors. Our focus on key customers and geographies allows us to consistently achieve high customer satisfaction ratings leading to a high level of customer retention and repeat business. Our highest concentrations of Sales and Service resources are in the United States, Western and Southern Africa, the Philippines, and the European Union. We maintain a presence in a number of other countries, some of which are based on customer locations and include, but not limited to, Nigeria, Kenya, Ghana, Ivory Coast, Algeria, South Africa, the United Arab Emirates, Saudi Arabia, Australia, Malaysia, New Zealand, Singapore, Slovenia and the Philippines.

In addition to our direct channel to market, we also have informal, and in some cases formal, relationships with original equipment manufacturers ("OEMs") and system integrators especially towards large and complex projects in National Security and Government related applications, which include, but not limited to, Nigeria, Kenya, Ghana, Ivory Coast, Algeria, South Africa, the United Arab Emirates, Saudi Arabia, Australia, Malaysia, New Zealand, Singapore, Slovenia and the Philippines. Our role in these relationships ranges from equipment supply only to being a sub-contractor for a portion of the project scope where we will supply equipment and a variety of design, deployment and maintenance services.

We also use indirect sales channels, including dealers, resellers and sales representatives, in the marketing and sale of some lines of products and equipment on a global basis. These independent representatives may buy for resale or, in

some cases, solicit orders from commercial or governmental customers for direct sales by us. Prices to the ultimate customer in many instances may be recommended or established by the independent representative and may be above or below our list prices. These independent representatives generally receive a discount from our list prices and are free to set the final sales prices paid by the customer.

We have repair and service centers in India, Nigeria, Ghana, Mexico, the Philippines, the United Kingdom and the United States. We have customer service and support personnel who provide customers with training, installation, technical support, maintenance and other services on systems under contract. We install and maintain customer equipment directly in some cases and contract with third-party service providers in other cases, depending on the equipment being installed and customer requirements.

The specific terms and conditions of our product warranties vary depending upon the product sold and country in which we do business. On direct sales, warranty periods generally start on the delivery date and continue for one to three years.

Manufacturing

Our global manufacturing strategy follows an outsourced manufacturing model using contract manufacturing partners in both the United States and Asia. Our strategy is based on balancing cost and supplier performance as well as taking into account qualification for localization requirements of certain market segments such as the Buy America statute. 

In accordance with our global logistics requirements and customer geographic distribution, we are engaged with contract manufacturing partners in Asia and the United States. All manufacturing operations have been certified to International Standards Organization 9001, a recognized international quality standard. We have also been certified to the TL 9000 standard, a telecommunication industry-specific quality system standard.

Backlog

Our backlog by geographic region is as follows:

Our backlog consists primarily of contracts or purchase orders for both product and service deliveries and extended service warranties. We regularly review our backlog to ensure that our customers continue to honor their purchase commitments and have the financial means to purchase and deploy our products and services in accordance with the terms of their purchase contracts.

We expect to substantially fill the backlog as of July 1, 2016 during fiscal 2017, but we cannot be assured that this will occur. Product orders in our current backlog are subject to changes in delivery schedules or to cancellation at the option of the purchaser without significant penalty. Accordingly, although useful for scheduling production, backlog as of any particular date may not be a reliable measure of sales for any future period because of the timing of orders, delivery intervals, customer and product mix and the possibility of changes in delivery schedules and additions or cancellations of orders. The backlog figures exclude advance payments and unearned income amounts.

Customers

Although we have a large customer base, during any given fiscal year or quarter, a small number of customers may account for a significant portion of our revenue.

During fiscal 2016 , the Mobile Telephone Networks Group ("MTN Group") in Africa accounted for 18% of our total revenue compared with 14% in fiscal 2015 and 17% in fiscal 2014 . We have entered into separate and distinct contracts with MTN Group as well as separate arrangements with MTN Group subsidiaries. The loss of all or a substantial portion of MTN Group's business could adversely affect our results of operations, cash flows and financial position.

Competition

The microwave and millimeter wave wireless networking business is a specialized segment of the wireless telecommunications industry that is sensitive to technological advancements and is extremely competitive. Our principal competitors include business units of large mobile and IP network infrastructure manufacturers such as Ericsson, Huawei, NEC and Nokia, as well as a number of other smaller public and other microwave specialists companies such as Ceragon, DragonWave and privately-held SIAE Microelectronica.

Some of our larger competitors may have greater name recognition, broader product lines (some including non-wireless telecommunications equipment and managed services), a larger installed base of products and longer-standing customer relationships. They may from time to time leverage their extensive overall portfolios into completely outsourced and managed network offerings restricting opportunities for specialist suppliers. In addition, some competitors may offer seller financing, which can be a competitive advantage under certain economic climates.

Some of our larger competitors may also act as systems integrators through which we sometimes distribute and sell products and services to end users.

The smaller independent private and public specialist competitors typically leverage new technologies and low products costs, but are generally less capable of offering a complete solution including professional services, especially in the North America and Africa regions which form the majority of our addressed market.

We concentrate on market opportunities that we believe are compatible with our resources, overall technological capabilities and objectives. Principal competitive factors are cost-effectiveness, product quality and reliability, technological capabilities, service, ability to meet delivery schedules and the effectiveness of dealers in international areas. We believe that the combination of our network and systems engineering support and service, global reach, technological innovation, agility and close collaborative relationships with our customers are the key competitive strengths for us. However, customers may still make decisions based primarily on factors such as price, financing terms and/or past or existing relationships, where it may be difficult for us to compete effectively or profitably.

Research and Development

We believe that our ability to enhance our current products, develop and introduce new products on a timely basis, maintain technological competitiveness and meet customer requirements is essential to our success. Accordingly, we allocate, and intend to continue to allocate, a significant portion of our resources to research and development efforts in two major product areas: backhaul solutions and network management systems. In addition, we are investing in key innovation that will help separate these products from the competition. The majority of such research and development resources will be used for point-to-point digital microwave radio systems for access, backhaul, trunking and license-exempt applications.

Our research and development expenditures totaled $20.8 million , or 7.7% of revenue, in fiscal 2016 , $25.4 million , or 7.6% of revenue, in fiscal 2015 , and $35.5 million , or 10.3% of revenue, in fiscal 2014 .

Research and development are primarily directed to the development of new products and to building technological capability. We are an industry innovator and intend to continue to focus significant resources on product development in an effort to maintain our competitiveness and support our entry into new markets.

Our product development teams numbered 134 employees as of July 1, 2016 , and were located in Santa Clara, California; Wellington, New Zealand; Ljubljana, Slovenia; and Montreal, Canada.

Raw Materials and Supplies

Because of the range of our products and services, as well as the wide geographic dispersion of our facilities, we use numerous sources for the wide array of raw materials needed for our operations and for our products, such as electronic components, printed circuit boards, metals and plastics. We are dependent upon suppliers and subcontractors for a large number of components and subsystems and upon the ability of our suppliers and subcontractors to adhere to customer or regulatory materials restrictions and meet performance and quality specifications and delivery schedules.

Our strategy for procuring raw material and supplies includes dual sourcing on strategic assemblies and components. In general, we believe this reduces our risk with regard to the potential financial difficulties in our supply base. In some instances, we are dependent upon one or a few sources, either because of the specialized nature of a particular item or because of local content preference requirements pursuant to which we operate on a given project.

Examples of sole or limited source categories include metal fabrications and castings, for which we own the tooling and therefore limit our supplier relationships, ASIC's and MMICs (types of integrated circuit used in manufacturing microwave radios), which we procure at volume discount from a single source. Our supply chain plan includes mitigation plans for alternative manufacturing sources and identified alternate suppliers.

Although we have been affected by performance issues of some of our suppliers and subcontractors, we have not been materially adversely affected by the inability to obtain raw materials or products. In general, any performance issues causing short-term material shortages are within the normal frequency and impact range experienced by high-tech manufacturing companies. They are due primarily to the highly technical nature of many of our purchased components.

Looking ahead, we anticipate standard lead times for our raw materials and supplies.

Patents and Other Intellectual Property

We consider our patents and other intellectual property rights, in the aggregate, to constitute an important asset. We own a portfolio of patents, trade secrets, know-how, confidential information, trademarks, copyrights and other intellectual property. We also license intellectual property to and from third parties. As of July 1, 2016 , we held 167 U.S. patents and 65 international patents and had 31 U.S. patent applications pending and 50 international patent applications pending. We do not consider our business to be materially dependent upon any single patent, license or other intellectual property right, or any group of related patents, licenses or other intellectual property rights. From time to time, we might engage in litigation to enforce our patents and other intellectual property or defend against claims of alleged infringement. Any of our patents, trade secrets, trademarks, copyrights and other proprietary rights could be challenged, invalidated or circumvented, or may not provide competitive advantages. Numerous trademarks used on or in connection with our products are also considered to be valuable assets.

In addition, to protect confidential information, including our trade secrets, we require our employees and contractors to sign confidentiality and invention assignment agreements. We also enter into non-disclosure agreements with our suppliers and appropriate customers to limit access to and disclosure of our proprietary information.

Although our ability to compete may be affected by our ability to protect our intellectual property, we believe that, because of the rapid pace of technological change in the wireless telecommunications industry, our innovative skills, technical expertise and ability to introduce new products on a timely basis will be more important in maintaining our competitive position than protection of our intellectual property. Trade secret, trademark, copyright and patent protections are important but must be supported by other factors such as the expanding knowledge, ability and experience of our personnel, new product introductions and product enhancements. Although we continue to implement protective measures and intend to vigorously defend our intellectual property rights, there can be no assurance that these measures will be successful.

Environmental and Other Regulations

Our facilities and operations, in common with those of our industry in general, are subject to numerous domestic and international laws and regulations designed to protect the environment, particularly with regard to wastes and emissions. We believe that we have complied with these requirements and that such compliance has not had a material adverse effect on our results of operations, financial condition or cash flows. Based upon currently available information, we do not expect expenditures to protect the environment and to comply with current environmental laws and regulations over the next several years to have a material impact on our competitive or financial position, but can give no assurance that such expenditures will not exceed current expectations. From time to time, we receive notices from the U.S. Environmental Protection Agency or equivalent state or international environmental agencies that we are a potentially responsible party under the Comprehensive Environmental Response, Compensation and Liability Act, which is commonly known as the Superfund Act, and equivalent laws. Such notices may assert potential liability for cleanup costs at various sites, which include sites owned by us, sites we previously owned and treatment or disposal sites not owned by us, allegedly containing hazardous substances attributable to us from past operations. We are not presently aware of any such liability that could be material to our business, financial condition or operating results, but due to the nature of our business and environmental risks, we cannot provide assurance that any such material liability will not arise in the future.

Electronic products are subject to environmental regulation in a number of jurisdictions. Equipment produced by us is subject to domestic and international requirements requiring end-of-life management and/or restricting materials in products delivered to customers. We believe that we have complied with such rules and regulations, where applicable, with respect to our existing products sold into such jurisdictions.

Radio communications are also subject to governmental regulation. Equipment produced by us is subject to domestic and international requirements to avoid interference among users of radio frequencies and to permit interconnection of telecommunications equipment. We believe that we have complied with such rules and regulations with respect to our existing products, and we intend to comply with such rules and regulations with respect to our future products. Reallocation of the frequency spectrum also could impact our business, financial condition and results of operations.

We are in the process of developing comprehensive policies and procedures concerning conflict minerals compliance.

Employees

As of July 1, 2016 we employed approximately 720 people, compared with approximately 780 as of the end of fiscal 2015 and approximately 960 as of the end of fiscal 2014 . Approximately 270 of our employees are located in the U.S. We also utilized approximately 70 independent contractors as of July 1, 2016 . None of our employees in the U.S. are represented by a labor union. In certain international subsidiaries, our employees are represented by workers' councils or statutory labor unions. In general, we believe that our employee relations are good.

Executive Officers of the Registrant

The name, age, position held with us, and principal occupation and employment during at least the past 5 years for each of our executive officers as of September 8, 2016 , are as follows:

There is no family relationship between any of our executive officers or directors, and there are no arrangements or understandings between any of our executive officers or directors and any other person pursuant to which any of them was appointed or elected as an officer or director, other than arrangements or understandings with our directors.

Additional information relating to our business and operations is set forth in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in this Annual Report on Form 10-K.

Item 1A. Risk Factors

In addition to the risks described elsewhere in this Annual Report on Form 10-K and in certain of our other filings with the SEC, the following risks and uncertainties, among others, could cause our actual results to differ materially from those contemplated by us or by any forward-looking statement contained herein. Prospective and existing investors are strongly urged to carefully consider the various cautionary statements and risks set forth in this Annual Report on Form 10-K and our other public filings.

We have many business risks including those related to our financial performance, investments in our common stock, operating our business and legal matters. The risks and uncertainties described below are not the only ones facing us. Additional risks and uncertainties may also impair our business operations. If any of these risks actually occur, our financial condition and results of operations could be materially and adversely affected.

We have not been profitable and must increase our revenues and reduce costs if we hope to achieve profitability.

As measured under U.S. generally accepted accounting principles ("U.S. GAAP"), we incurred net losses of $29.6 million in fiscal 2016 , $24.6 million in fiscal 2015 and $51.1 million in fiscal 2014 and have been unprofitable since we became a public company in January 2007. We also have incurred losses from operations in all fiscal years since we became a public company, although we previously generated cash from operations in fiscal 2013, 2012, 2010 and 2009.

Throughout fiscal 2016 we experienced strong price competition for new business in all regions while major customer consolidations from prior years also put pressure on revenue and gross margin. We saw pricing pressures in all markets, with increased pressure in international markets. Customer consolidation may have an increasing negative impact on our revenue if Aviat is not selected as a vendor for the products and/or services we provide. In order to counter pricing pressures, we invested heavily in product improvements to reduce unit costs and enhance product features, decreased overall company expenses, and worked with our vendors to attain more favorable pricing. If we are unable to reduce product unit costs associated with enhanced product features, including payments to contract manufacturers and other suppliers, or achieve the projected cost reductions, we may not achieve profitability.

We cannot be certain that these actions or others that we may take in the future will result in operating profitability or net income as determined under U.S. GAAP.

O ur sales cycle may be lengthy, and the timing of sales, along with additional services such as warehousing, inventory management, installation and implementation of our products within our customers' networks, may extend over more than one period, which can make our operating results difficult to predict.

We anticipate difficulty in accurately predicting the timing of the sale of products and amounts of revenue generated from sales of our products, primarily in developing countries. The establishment of a business relationship with a potential customer is a lengthy process, generally taking several months and sometimes longer. Following the establishment of the relationship, the negotiation of purchase terms can be time-consuming, and a potential customer may require an extended evaluation and testing period. We expect that our product sales cycle, which results in our products being designed into our customers' networks, could take 12 to 24 months. A number of factors can contribute to the length of the sales cycle, including technical evaluations of our products, the design process required to integrate our products into our customers' networks and warehousing and/or inventory management services that may be requested by certain large customers. In anticipation of product orders, we may incur substantial costs before the sales cycle is complete and before we receive any customer payments. Specifically, should a customer require warehousing and/or inventory management services, such services may impact our operating results in any period due to the costs associated with providing such services and the fact that the timing of the revenue recognition may be delayed. As a result, in the event that a sale is not completed or is

canceled or delayed, we may have incurred substantial expenses, making it more difficult for us to become profitable or otherwise negatively impacting our financial results. Furthermore, because of our lengthy sales cycle, our recognition of revenue from our selling efforts may be substantially delayed, our ability to forecast our future revenue may be more limited and our revenue may fluctuate significantly from quarter to quarter.

Once a purchase agreement has been executed, the timing and amount of revenue, if applicable, may remain difficult to predict. The completion of services such as warehousing and inventory management, installation and testing of the customer's networks and the completion of all other suppliers network elements are subject to the customer's timing and efforts and other factors outside our control, each of which may prevent us from making predictions of revenue with any certainty and could cause us to experience substantial period-to-period fluctuations in our operating results.

Our average sales prices may decline in the future.

We are experiencing, and are likely to continue to experience, declining sales prices. This price pressure is likely to result in downward pricing pressure on our products and services. As a result, we are likely to experience declining average sales prices for our products. Our future profitability will depend upon our ability to improve manufacturing efficiencies, reduce costs of materials used in our products and to continue to introduce new lower-cost products and product enhancements and if we are unable to do so, we may not be able to respond to pricing pressures. If we are unable to respond to increased price competition, our business, financial condition and results of operations will be harmed. Because customers frequently negotiate supply arrangements far in advance of delivery dates, we may be required to commit to price reductions for our products before we are aware of how, or if, cost reductions can be obtained. As a result, current or future price reduction commitments and any inability on our part to respond to increased price competition could harm our business, financial condition and results of operations.

We may not be able to obtain capital when desired on favorable terms, if at all, or without dilution to our stockholders.

We believe that our existing cash and cash equivalents, the available line of credit under our credit facility and future cash collections from customers will be sufficient to provide for our anticipated requirements for working capital and capital expenditures for the next 12 months and the foreseeable future. However, it is possible that we may not generate sufficient cash flow from operations or otherwise have the capital resources to meet our longer term capital needs. If this occurs, we may need to sell assets, reduce capital expenditures, or obtain additional equity or debt financing. We cannot assure you that additional financing will be available on terms favorable to us, or at all. If adequate funds are not available or are not available on acceptable terms if and when needed, our business, financial condition and results of operations could be harmed.

If we raise additional funds through the issuance of equity or convertible debt securities, the percentage ownership of our stockholders could be significantly diluted, and these newly-issued securities may have rights, preferences or privileges senior to those of existing stockholders.

Due to the volume of our international sales, we may be susceptible to a number of political, economic and geographic risks that could harm our business.

We are highly dependent on sales to customers outside the U.S. In fiscal 2016, 2015 and 2014 , our sales to international customers accounted for 55% , 55% and 60% , respectively, of total revenue. Significant portions of our international sales are in less developed countries. Our international sales are likely to continue to account for a large percentage of our products and services revenue for the foreseeable future. As a result, the occurrence of any international, political, economic or geographic event could result in a significant decline in revenue. In addition, compliance with complex foreign and U.S. laws and regulations that apply to our international operations increases our cost of doing business in international jurisdictions. These numerous and sometimes conflicting laws and regulations include internal control and disclosure rules, data privacy and filtering requirements, anti-corruption laws, such as the Foreign Corrupt Practices Act, and other local laws prohibiting corrupt payments to governmental officials, and anti-competition regulations, among others. Violations of these laws and regulations could result in fines and penalties, criminal sanctions against us, our officers, or our employees, prohibitions on the conduct of our business and on our ability to offer our products and services in one or more countries, and could also materially affect our brand, our international expansion efforts, our ability to attract and retain employees, our business, and our operating results. Although we have implemented policies and procedures designed to ensure compliance with these laws and regulations, there can be no assurance that our employees, contractors, or agents will not violate our policies.

Some of the risks and challenges of doing business internationally include:

While these factors and the impacts of these factors are difficult to predict, any one or more of them could adversely affect our business, financial condition and results of operations in the future.

Credit and commercial risks and exposures could increase if the financial condition of our customers declines.

A substantial portion of our sales are to customers in the telecommunications industry. These customers may require their suppliers to provide extended payment terms, direct loans or other forms of financial support as a condition to obtaining commercial contracts. In addition, if local currencies cannot be hedged, we have an inherent exposure in our ability to convert monies at favorable rates from or to U.S. dollars. More generally, we expect to routinely enter into long-term contracts involving significant amounts to be paid by our customers over time. Pursuant to these contracts, we may deliver products and services representing an important portion of the contract price before receiving any significant payment from the customer. As a result of the financing that may be provided to customers and our commercial risk exposure under long-term contracts, our business could be adversely affected if the financial condition of our customers erodes. Over the past few years, certain of our customers have filed with the courts seeking protection under the bankruptcy or reorganization laws of the applicable jurisdiction, or have experienced financial difficulties. The financial healthiness may be exacerbated in many emerging markets, where our customers are being affected not only by recession, but by deteriorating local currencies and a lack of credit. Upon the financial failure of a customer, we may experience losses on credit extended and loans made to such customer, losses relating to our commercial risk exposure and the loss of the customer's ongoing business. If customers fail to meet their obligations to us, we may experience reduced cash flows and losses in excess of reserves, which could materially adversely impact our results of operations and financial position.

We may undertake further restructuring activities, which may adversely impact our operations, and we may not realize all of the anticipated benefits of these activities or any potential future restructurings. Any restructuring activities may harm our business.

We continue to evaluate our business to determine the potential need to realign our resources as we continue to transform our business in order to achieve desired cost savings in an increasingly competitive market. In prior years and again in fiscal 2016, we have undertaken a series of steps to restructure our operations involving, among other things and depending on the year, reductions of our workforce, the relocation of our corporate headquarters and the reduction and outsourcing of manufacturing activities. We incurred restructuring charges of $2.5 million , $4.9 million and $11.2 million in fiscal 2016, 2015 and 2014 , respectively.

We have based our restructuring efforts on assumptions and plans regarding the appropriate cost structure of our business based on our product mix and projected sales, among other factors. Some of our assumptions include the elimination of jobs and the outsourcing of certain functions to reduce our operating expenses. These assumptions may not be accurate and we may not be able to operate in accordance with our plans. Should this occur we may determine that we must incur additional restructuring charges in the future. Moreover, we cannot assure you that we will realize all of the anticipated benefits of our restructuring actions or that we will not further reduce or otherwise adjust our workforce or exit, or dispose of, certain businesses and product lines. Any decision to further limit investment, exit, or disposal of businesses or product lines may result in the recording of additional restructuring charges. Consequently, the costs actually incurred in connection with the restructuring efforts may be higher than originally planned and may not lead to the anticipated cost savings and/or improved results. For example, if we consolidate additional facilities in the future, we

may incur additional restructuring and related expenses, which could have a material adverse effect on our business, financial condition or results of operations.

Our restructuring actions could harm our relationships with our employees and impact our ability to recruit new employees.

Employees, whether or not directly affected by any restructuring actions that we undertake, may seek employment with our business partners, customers or competitors. We cannot assure you that the confidential nature of our proprietary information will not be compromised by any such employees who terminate their employment with us. Further, we believe that our future success will depend in large part upon our ability to attract, motivate and retain highly skilled personnel. We may have difficulty attracting and retaining such personnel as a result of a perceived risk of future workforce reductions, and we may terminate the employment of employees as part of a restructuring and later determine that such employees were important to the success of the ongoing business.

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

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

Our success will depend on new products introduced to the marketplace in a timely manner, successfully completing product transitioning and achieving customer acceptance.

The market for our products and services is characterized by rapid technological change, evolving industry standards and frequent new product introductions. Our future success will depend, in part, on continuous, timely development and introduction of new products and enhancements that address evolving market requirements and are attractive to customers. If we fail to develop or introduce on a timely basis new products or product enhancements or features that achieve market acceptance, our business may suffer. Additionally, we work closely with a variety of third party partners to develop new product features and new platforms. Should our partners face delays in the development process, then the timing of the rollout of our new products may be significantly impacted which may negatively impact our revenue and gross margin. Another factor impacting our future success is the growth in the customer demand of our new products. Rapidly changing technology, frequent new products introductions and enhancements, short product life cycles and changes in customer requirements characterize the markets for our products. We believe that successful new product introductions provide a significant competitive advantage because of the significant resources committed by customers in adopting new products and their reluctance to change products after these resources have been expended. We have spent, and expect to continue to spend, significant resources on internal research and development to support our effort to develop and introduce new products and enhancements.

As we transition to new product platforms, we face significant risk that the development of our new products may not be accepted by our current customers or by new customers. To the extent that we fail to introduce new and innovative products that are adopted by customers, we could fail to obtain an adequate return on these investments and could lose market share to our competitors, which could be difficult or impossible to regain. Similarly we may face decreased revenue, gross margins and profitability due to a rapid decline in sales of current products as customers hold spending to focus purchases on new product platforms. We could incur significant costs in completing the transition, including costs of inventory write-downs of the current product as customers transition to new product platforms. In addition, products or technologies developed by others may render our products noncompetitive or obsolete and result in significant reduction in orders from our customers and the loss of existing and prospective customers.

Our quarterly results may be volatile, which can adversely affect the trading price of our common stock.

Our quarterly operating results may vary significantly for a variety of reasons, many of which are outside our control. These factors could harm our business and include, among others:

Our quarterly results are expected to be difficult to predict and delays in product delivery or closing a sale can cause revenue, margins and net income or loss to fluctuate significantly from anticipated levels. A substantial portion of our contracts are completed in the latter part of a quarter and a significant percentage of these are large orders. Because a significant portion of our cost structure is largely fixed in the short term, revenue shortfalls tend to have a disproportionately negative impact on our profitability and can increase our inventory. The number of large new transactions also increases the risk of fluctuations in our quarterly results because a delay in even a small number of these transactions could cause our quarterly revenues and profitability to fall significantly short of our predictions. In addition, we may increase spending in response to competitive actions or in pursuit of new market opportunities. Accordingly, we cannot provide assurances that we will be able to achieve profitability in the future or that if profitability is attained, that we will be able to sustain profitability, particularly on a quarter-to-quarter basis.

We face strong competition for maintaining and improving our position in the market, which can adversely affect our revenue growth and operating results.

The wireless access, interconnection and backhaul business is a specialized segment of the wireless telecommunications industry and is extremely competitive. Competition in this segment is intense, and we expect it to increase. Some of our competitors have more extensive engineering, manufacturing and marketing capabilities and significantly greater financial, technical and personnel resources than we have. In addition, some of our competitors have greater name recognition, broader product lines, a larger installed base of products and longer-standing customer relationships. Our competitors include established companies, such as Ericsson, Huawei, NEC and Nokia, as well as a number of other public and private companies, such as Ceragon, DragonWave and SIAE. Some of our competitors are OEMs or systems integrators through whom we market and sell our products, which means our business success may depend on these competitors to some extent. One or more of our largest customers could internally develop the capability to manufacture products similar to those manufactured or outsourced by us and, as a result, the demand for our products and services may decrease.

In addition, we compete for acquisition and expansion opportunities with many entities that have substantially greater resources than we have. Our competitors may enter into business combinations in order to accelerate product development or to compete more aggressively and we may lack the resources to meet such enhanced competition.

Our ability to compete successfully will depend on a number of factors, including price, quality, availability, customer service and support, breadth of product lines, product performance and features, rapid time-to-market delivery capabilities, reliability, timing of new product introductions by us, our customers and competitors, the ability of our customers to obtain financing and the stability of regional sociopolitical and geopolitical circumstances, and the ability of large competitors to obtain business by providing more seller financing especially for large transactions. We can give no

assurances that we will have the financial resources, technical expertise, or marketing, sales, distribution, customer service and support capabilities to compete successfully, or that regional sociopolitical and geographic circumstances will be favorable for our successful operation.

If we fail to accurately forecast our manufacturing requirements or customer demand, we could incur additional costs, which would adversely affect our business and results of operations.

If we fail to accurately predict our manufacturing requirements or forecast customer demand, we may incur additional costs of manufacturing and our gross margins and financial results could be adversely affected. If we overestimate our requirements, our contract manufacturers may experience an oversupply of components and assess us charges for excess or obsolete components that could adversely affect our gross margins. If we underestimate our requirements, our contract manufacturers may have inadequate inventory or components, which could interrupt manufacturing and result in higher manufacturing costs, shipment delays, damage to customer relationships and/or our payment of penalties to our customers. Our contract manufacturers also have other customers and may not have sufficient capacity to meet all of their customer's needs, including ours, during periods of excess demand.

Part of our inventory may be written off, which would increase our cost of revenues. In addition, we may be exposed to inventory-related losses on inventories purchased by our contract manufacturers.

During fiscal 2016, 2015 and 2014 , we recorded charges to reduce the carrying value of our inventory which totaled $9.9 million , $8.0 million and $7.2 million , respectively. Such charges equaled 3.7% , 2.4% and 2.1% of our revenue in fiscal 2016, 2015 and 2014 , respectively. These charges were primarily due to excess and obsolete inventory resulting from lower forecast, product transitioning or discontinuance.

Inventory of raw materials, work in-process or finished products may accumulate in the future, and we may encounter losses due to a variety of factors, including:

Further, our inventory of finished products may accumulate as the result of inaccuracies in the forecasting process, cancellation of customer orders or our customers' refusal to confirm the acceptance of our products. Our forecasting process is based on information discussed with customers concerning future orders. If a customer chooses to revise or hold on placing the order, we may see an unfavorable impact on our inventory given the customization that is involved in our products. Our contract manufacturers are required to purchase inventory based on manufacturing projections we provide to them. If actual orders from our customers are lower than these manufacturing projections, our contract manufacturers will have excess inventory of raw materials or finished products which we would be required to purchase. In addition, we require our contract manufacturers from time to time to purchase more inventory than is immediately required, and to partially assemble components, in order to shorten our delivery time in case of an increase in demand for our products. In the absence of such increase in demand, we may need to compensate our contract manufacturers. If we are required to purchase excess inventory from our contract manufacturers or otherwise compensate our contract manufacturers for purchasing excess inventory, our business, financial condition and results of operations could be materially adversely affected. We also may purchase components or raw materials from time to time for use by our contract manufacturers in the manufacturing of our products. These purchases are based on our own manufacturing projections. If our actual orders are lower than these manufacturing projections, we may accumulate excess inventory, which we may be required to write down. If we are forced to write down inventory other than in the normal course of business, our business, financial condition and results of operations could be materially adversely affected.

The effects of the poor global financial and economic conditions in certain markets has had, and may continue to have, significant effects on our customers and suppliers, and has in the past, and may in the future have, a material adverse effect on our business, operating results, financial condition and stock price.

The effects of poor global financial and economic conditions in certain markets include, among other things, significant reductions in available capital and liquidity from banks and other providers of credit, substantial reductions and/or fluctuations in equity and currency values worldwide.

Poor economic conditions in certain markets have adversely affected and may continue to adversely affect our customers' access to capital and/or willingness to spend capital on our products, and/or their levels of cash liquidity and/or their ability and/or willingness to pay for products that they will order or have already ordered from us, or result in their ceasing operations. Further, we have experienced an increasing number of our customers, principally in emerging markets, requesting longer payment terms, lease or vendor financing arrangements, longer terms for the letters of credit securing purchases of our products and services, which could potentially negatively impact our orders, revenue conversion cycle, and cash flows.

In seeking to reduce their expenses, we have also seen significant pressure from our customers to lower prices for our products as they try to improve their operating performance and procure additional capital equipment within their reduced budget levels. To the extent that we lower prices on our products and services, our orders, revenues, and gross margins may be negatively impacted. Additionally, certain emerging markets are particularly sensitive to pricing as a key differentiator. Where price is a primary decision driver, we may not be able to effectively compete or we may choose not to compete due to unacceptable margins.

In addition, poor economic conditions in certain markets could materially adversely affect our suppliers' access to capital and liquidity with which to maintain their inventories, production levels, and/or product quality, could cause them to raise prices or lower production levels, or result in their ceasing operations. Further, with respect to our credit facility discussed under "Liquidity, Capital Resources and Financial Strategies" in Item 7 of this Annual Report on Form 10-K, if continued uncertain economic conditions adversely affect Silicon Valley Bank, our ability to access the funds available under our credit facility could be materially adversely affected.

The potential effects of these economic factors are difficult to forecast and mitigate. As a consequence, our operating results for a particular period are difficult to predict, and, therefore, prior results are not necessarily indicative of results to be expected in future periods. Any of the foregoing effects could have a material adverse effect on our business, results of operations, and financial condition and could adversely affect our stock price.

If we fail to effectively manage our contract manufacturer relationships, we could incur additional costs or be unable to timely fulfill our customer commitments, which would adversely affect our business and results of operations and, in the event of an inability to fulfill commitments, would harm our customer relationships.

We outsource all of our manufacturing and a substantial portion of our repair service operations to independent contract manufacturers and other third parties. Our contract manufacturers typically manufacture our products based on rolling forecasts of our product needs that we provide to them on a regular basis. The contract manufacturers are responsible for procuring components necessary to build our products based on our rolling forecasts, building and assembling the products, testing the products in accordance with our specifications and then shipping the products to us. We configure the products to our customer requirements, conduct final testing and then ship the products to our customers. Although we currently partner with multiple major contract manufacturers, there can be no assurance that we will not encounter problems as we are dependent on contract manufacturers to provide these manufacturing services or that we will be able to replace a contract manufacturer that is not able to meet our demand.

In addition, if we fail to effectively manage our relationships with our contract manufacturers or other service providers, or if one or more of them should not fully comply with their contractual obligations or should experience delays, disruptions, component procurement problems or quality control problems, then our ability to ship products to our customers or otherwise fulfill our contractual obligations to our customers could be delayed or impaired which would adversely affect our business, financial results and customer relationships.

We depend on sole or limited sources for some key components and failure to receive timely delivery of any of these components could result in deferred or lost sales.

In some instances, we are dependent upon one or a few sources, either because of the specialized nature of a particular item or because of local content preference requirements pursuant to which we operate on a given project. Examples of sole or limited sourcing categories include metal fabrications and castings, for which we own the tooling and therefore limit our supplier relationships, and MMICs (a type of integrated circuit used in manufacturing microwave radios), which we procure at a volume discount from a single source. Our supply chain plan includes mitigation plans for alternative manufacturing sources and identified alternate suppliers. However, if these alternatives cannot address our requirements when our existing sources of these components fail to deliver them on time, we could suffer delayed shipments, canceled orders and lost or deferred revenues, as well as material damage to our customer relationships. Should this occur, our operating results, cash flows and financial condition could be materially adversely affected.

As a result of changes in tax laws, treaties, rulings, regulations or agreements, or their interpretation, of any country in which we operate, the loss of a major tax dispute or a successful challenge to our operating structure, intercompany pricing policies or the taxable presence of our key subsidiaries in certain countries, or other factors, our effective tax rate could be highly volatile and could adversely affect our operating results.

We operate in multiple jurisdictions and our profits are taxed pursuant to the tax laws of these jurisdictions. Our future effective tax rate may be adversely affected by a number of factors, many of which are outside of our control, including:

Any significant increase in our future effective tax rates could impact our results of operations for future periods adversely.

O ur ability to use net operating loss carryforwards to offset future taxable income for U.S. federal income tax purposes and other tax benefits may be limited.

Section 382 of the Internal Revenue Code of 1986, as amended (the "Code") imposes an annual limitation on the amount of taxable income that may be offset if a corporation experiences an "ownership change" as defined in Section 382 of the Code. An ownership change occurs when a company's "five-percent shareholders" (as defined in Section 382 of the Code) collectively increase their ownership in the company by more than 50 percentage points (by value) over a rolling three-year period. Additionally, various states have similar limitations on the use of state net operating losses ("NOL") following an ownership change.

If we experience an ownership change, our ability to use our NOLs, any loss or deducting attributable to a "net unrealized built-in loss" and other tax attributes (collectively, the "Tax Benefits") could be substantially limited, and the timing of the usage of the Tax Benefits could be substantially delayed, which could significantly impair the value of the Tax Benefits.  There is no assurance that we will be able to fully utilize the Tax Benefits and we could be required to record an additional valuation allowance related to the amount of the Tax Benefits that may not be realized, which could adversely impact our result of operations.

We believe that these Tax Benefits are a valuable asset for us. On September 6, 2016, our Board of Directors approved a Tax Benefit Preservation Plan (the "Plan") in an effort to protect our Tax Benefits during the effective period of the Plan. Further, on September 6, 2016, our Board of Directors adopted certain amendments to our Amended and Restated Certificate of Incorporation, as amended (the "Charter Amendments"), which are intended to preserve the Tax Benefits by restricting certain transfers of our common stock. The Plan and the Charter Amendments will be submitted to a stockholder vote at our 2016 annual meeting of stockholders. If our stockholders do not approve the Plan, it will expire. If our stockholders do not approve the Charter Amendments, they will not become effective. Although the Plan and the Charter Amendments are intended to reduce the likelihood of an "ownership change" that could adversely affect us, there is no assurance that the restrictions on transferability in the Plan and the Charter Amendments will prevent all transfers that could result in such an "ownership change." There also can be no assurance that the transfer restrictions in the Charter Amendments, if they become effective, will be enforceable against all of our stockholders absent a court determination confirming such enforceability. The transfer restrictions may be subject to challenge on legal or equitable grounds.

The Plan and the Charter Amendments could make it more difficult for a third party to acquire, or could discourage a third party from acquiring, us or a large block of our common stock. A third party that acquires 4.9% or more of our

common stock could suffer substantial dilution of its ownership interest under the terms of the Plan through the issuance of common stock or common stock equivalents to all stockholders other than the acquiring person. The acquisition may also be void under the Charter Amendments.

The foregoing provisions may adversely affect the marketability of our common stock by discouraging potential investors from acquiring our stock. In addition, these provisions could delay or frustrate the removal of incumbent directors and could make more difficult a merger, tender offer or proxy contest involving us, or impede an attempt to acquire a significant or controlling interest in us, even if such events might be beneficial to us and our stockholders.

Our customers may not pay for products and services in a timely manner, or at all, which would decrease our cash flows and adversely affect our working capital.

Our business requires extensive credit risk management that may not be adequate to protect against customer nonpayment. A risk of non-payment by customers is a significant focus of our business. We expect a significant amount of future revenue to come from international customers in developing countries. We do not generally expect to obtain collateral for sales, although we require letters of credit or credit insurance as appropriate for international customers. For information regarding the percentage of revenue attributable to certain key customers, see the risks discussed in the following risk factor. Our historical accounts receivable balances have been concentrated in a small number of significant customers. Unexpected adverse events impacting the financial condition of our customers, bank failures or other unfavorable regulatory, economic or political events in the countries in which we do business may impact collections and adversely impact our business, require increased bad debt expense or receivable write-offs and adversely impact our cash flows, financial condition and operating results, which could also result in a breach of our bank covenants.

Because a significant amount of our revenue may come from a limited number of customers, the termination of any of these customer relationships may adversely affect our business.

Sales of our products and services historically have been concentrated in a small number of customers. Principal customers for our products and services include domestic and international wireless/mobile service providers, OEMs, as well as private network users such as public safety agencies; government institutions; and utility, pipeline, railroad and other industrial enterprises that operate broadband wireless networks. During fiscal 2016, 2015 and 2014 , we had one international customer in Africa, MTN Group that accounted for 18% , 14% and 17% , respectively, of our total revenue. Although we have a large customer base, during any given quarter a small number of customers may account for a significant portion of our revenue.

It is possible that a significant portion of our future product sales also could become even more concentrated in a limited number of customers. In addition, product sales to major customers have varied widely from period to period. The loss of any existing customer, a significant reduction in the level of sales to any existing customer, or our inability to gain additional customers could result in declines in our revenue or an inability to grow revenue. In addition, further consolidation of our potential customer base could result in purchasing decision delays as consolidating customers integrate their operations and could generally reduce our opportunities to win new customers to the extent that the number of potential customers decreases. Furthermore, as our customers become larger, they may have more leverage to negotiate better pricing which could adversely affect our revenues and gross margins.

Consolidation within the telecommunications industry could result in a decrease in our revenue.

The telecommunications industry has experienced significant consolidation among its participants, and we expect this trend to continue. Some operators in this industry have experienced financial difficulty and have filed, or may file, for bankruptcy protection. Other operators may merge and one or more of our competitors may supply products to the customers of the combined company following those mergers. This consolidation could result in purchasing decision delays and decreased opportunities for us to supply products to companies following any consolidation. This consolidation may also result in lost opportunities for cost reduction and economies of scale.

We continually evaluate strategic opportunities which could involve merger and/or acquisition activities that could disrupt our operations and harm our operating results.

Our growth depends upon market growth, our ability to enhance our existing products and our ability to introduce new products on a timely basis. We intend to continue to address the need to develop new products and enhance existing products through acquisitions, or "tuck-ins," product lines, technologies, and personnel. Acquisitions involve numerous risks, including the following:

Acquisitions may also cause us to:

Mergers and acquisitions of high-technology companies are inherently risky and subject to many factors outside of our control. No assurance can be given that our previous or future acquisitions will be successful and will not materially adversely affect our business, operating results or financial condition. Failure to manage and successfully integrate acquisitions could materially harm our business and operating results. Even when an acquired company has already developed and marketed products, there can be no assurance that product enhancements will be made in a timely fashion or that pre-acquisition due diligence will have identified all possible issues that might arise with respect to such products.

If we are unable to adequately protect our intellectual property rights, we may be deprived of legal recourse against those who misappropriate our intellectual property.

Our ability to compete will depend, in part, on our ability to obtain and enforce intellectual property protection for our technology in the U.S. and internationally. We rely upon a combination of trade secrets, trademarks, copyrights, patents and contractual rights to protect our intellectual property. In addition, we enter into confidentiality and invention assignment agreements with our employees, and enter into non-disclosure agreements with our suppliers and appropriate customers so as to limit access to and disclosure of our proprietary information. We cannot give assurances that any steps taken by us will be adequate to deter misappropriation or impede independent third-party development of similar technologies. In the event that such intellectual property arrangements are insufficient, our business, financial condition and results of operations could be harmed. We cannot provide assurances that the protection provided to our intellectual property by the laws and courts of particular nations will be substantially similar to the protection and remedies available under U.S. law. Furthermore, we cannot provide assurances that third parties will not assert infringement claims against us based on intellectual property rights and laws in other nations that are different from those established in the U.S.

If we fail to develop and maintain distribution and licensing relationships, our revenue may decrease.

Although a majority of our sales are made through our direct sales force, we also market our products through indirect sales channels such as independent agents, resellers, OEMs and systems integrators. These relationships enhance our ability to pursue major contract awards and, in some cases, are intended to provide our customers with easier access to financing and a greater variety of equipment and service capabilities, which an integrated system provider should be able to offer. We may not be able to maintain our current relationships or develop new ones. If additional relationships are

developed, they may not be successful. Furthermore, as we consider increasing licensing revenue based on upgraded technology, we may not be successful in transitioning customers to the planned software upgrades. Our inability to establish or maintain these distribution and licensing relationships could restrict our ability to market our products and thereby result in significant reductions in revenue. If these revenue reductions occur, our business, financial condition and results of operations would be harmed.

If sufficient radio frequency spectrum is not allocated for use by our products, or we fail to obtain regulatory approval for our products, our ability to market our products may be restricted.

We will be affected by the allocation and auction of the radio frequency spectrum by governmental authorities both in the U.S. and internationally. These governmental authorities may not allocate sufficient radio frequency spectrum for use by our products or we may not be successful in obtaining regulatory approval for our products from these authorities. Historically, in many developed countries, the unavailability of frequency spectrum has inhibited the growth of wireless telecommunications networks. In addition, to operate in a jurisdiction, we must obtain regulatory approval for our products. Each jurisdiction in which we market our products has its own regulations governing radio communications. Products that support emerging wireless telecommunications services can be marketed in a jurisdiction only if permitted by suitable frequency allocations, auctions and regulations. The process of establishing new regulations is complex and lengthy. If we are unable to obtain sufficient allocation of radio frequency spectrum by the appropriate governmental authority or obtain the proper regulatory approval for our products, our business, financial condition and results of operations may be harmed.

Radio communications are subject to regulation by U.S. and foreign laws and international treaties. Generally, our products need to conform to a variety of United States and international requirements established to avoid interference among users of transmission frequencies and to permit interconnection of telecommunications equipment. Any delays in compliance with respect to our future products could delay the introduction of such products.

Our business is subject to changing regulation of corporate governance, public disclosure and anti-bribery measures which have resulted in increased costs and may continue to result in additional costs in the future and/or potential liabilities.

We are subject to rules and regulations of federal and state regulatory authorities, The NASDAQ Stock Market LLC ("NASDAQ") and financial market entities charged with the protection of investors and the oversight of companies whose securities are publicly traded, and foreign and domestic legislative bodies. During the past few years, these entities, including the Public Company Accounting Oversight Board, the SEC, NASDAQ and several foreign governments such as the governments of the United Kingdom and Brazil, have issued requirements, laws and regulations and continue to develop additional requirements, laws and regulations, most notably the Sarbanes-Oxley Act of 2002 ("SOX"), and recent laws and regulations regarding bribery and unfair competition. Our efforts to comply with these requirements and regulations have resulted in, and are likely to continue to result in, increased general and administrative expenses and a diversion of substantial management time and attention from revenue-generating activities to compliance activities.

Moreover, because these laws, regulations and standards are subject to varying interpretations, their application in practice may evolve over time as new guidance becomes available. This evolution may result in continuing uncertainty regarding compliance matters and additional costs potentially necessitated by ongoing revisions to our disclosure and governance practices. Finally, if we are unable to ensure compliance with such requirements, laws, or regulations, we may be subject to costly prosecution and liability, and resulting reputational harm, from such noncompliance.

In previous periods, we identified material weaknesses in our internal control over financial reporting and, if we are unable to satisfy regulatory requirements relating to internal controls or if our internal control over financial reporting is not effective, our business and stock price could be adversely affected.

In connection with Section 404 of the Sarbanes-Oxley Act, we have identified in the past and may, in the future, identify deficiencies in our internal control over financial reporting. In connection with the audit of our consolidated financial statements as of and for the years ended July 3, 2015 and June 27, 2014, we have concluded that there were material weaknesses related to our internal control over financial reporting. A material weakness is defined as a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the company's annual or interim consolidated financial statements will not be prevented or detected on a timely basis. As a result of these material weaknesses, our management concluded that our internal control over financial reporting was not effective as of July 3, 2015 and June 27, 2014, based on criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO") in Internal Control-An Integrated Framework (2013). Although we believe that we have remediated these material weaknesses as of July 1, 2016, if we identify additional material weaknesses in our internal controls are identified in the future, our consolidated financial statements may contain material misstatements and we could be required to restate our financial results. We could also be subject to litigation which, whether meritorious or not, could be time consuming, costly or divert significant operational resources. Further, we could lose investor confidence in the accuracy and completeness of our financial reports, and our reputation, business, results of operations and stock price could be adversely affected.

Our products are used in critical communications networks which may subject us to significant liability claims.

Because our products are used in critical communications networks, we may be subject to significant liability claims if our products do not work properly. We warrant to our current customers that our products will operate in accordance with our product specifications. If our products fail to conform to these specifications, our customers could require us to remedy the failure or could assert claims for damages. The provisions in our agreements with customers that are intended to limit our exposure to liability claims may not preclude all potential claims. In addition, any insurance policies we have may not adequately limit our exposure with respect to such claims. Liability claims could require us to spend significant time and money in litigation or to pay significant damages. Any such claims, whether or not successful, would be costly and time-consuming to defend, and could divert management's attention and seriously damage our reputation and our business.

We may be subject to litigation regarding our intellectual property. This litigation could be costly to defend and resolve, and could prevent us from using or selling the challenged technology.

The wireless telecommunications industry is characterized by vigorous protection and pursuit of intellectual property rights, which has resulted in often protracted and expensive litigation. Any litigation regarding patents or other intellectual property could be costly and time-consuming and could divert our management and key personnel from our business operations. The complexity of the technology involved and the uncertainty of intellectual property litigation increase these risks. Such litigation or claims could result in substantial costs and diversion of resources. In the event of an adverse result in any such litigation, we could be required to pay substantial damages, cease the use and transfer of allegedly infringing technology or the sale of allegedly infringing products and expend significant resources to develop non-infringing technology or obtain licenses for the infringing technology. We can give no assurances that we would be successful in developing such non-infringing technology or that any license for the infringing technology would be available to us on commercially reasonable terms, if at all. This could have a materially adverse effect on our business, results of operation, financial condition, competitive position and prospects.

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

In the ordinary course of business, we store sensitive data, including intellectual property, our proprietary business information and proprietary information 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 ours, are subject to a wide variety of attacks on their networks on an ongoing basis. Despite our security measures, our 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 security products, regardless of whether the breach is attributable to our products, the market perception of the effectiveness of our products could be harmed. 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. 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 damage may differ based on the identity and motive of the programmer or hacker, which are often difficult to identify.

Anti-takeover provisions of Delaware law, the Plan, and provisions in our Amended and Restated Certificate of Incorporation, as amended, and Amended and Restated Bylaws could make a third-party acquisition of us difficult.

Because we are a Delaware corporation, the anti-takeover provisions of Delaware law could make it more difficult for a third party to acquire control of us, even if the change in control would be supported by our stockholders. We are subject to the provisions of Section 203 of the General Corporation Law of Delaware, which prohibits us from engaging in certain business combinations, unless the business combination is approved in a prescribed manner. In addition, our Amended and Restated Certificate of Incorporation, as amended, and Amended and Restated Bylaws also contain certain provisions that may make a third-party acquisition of us difficult, including the ability of the Board of Directors to issue preferred stock and the requirement that nominations for directors and other proposals by stockholders must be made in advance of the meeting at which directors are elected or the proposals are voted upon.

In addition, the Plan and the Charter Amendments could make an acquisition of us more difficult, and certain acquisitions may also be void under the Charter Amendments. The risks associated with the Plan and the Charter Amendments are described in more detail above under the heading "Our ability to use net operating loss carryforwards to offset future taxable income for U.S. federal income tax purposes and other tax benefits may be limited."

Item 1B. Unresolved Staff Comments

None.

Item 2.  Properties

As of July 1, 2016 , we leased approximately 294,000 square feet of facilities worldwide, with approximately 62% in the United States, mostly in California, Texas, and North Carolina. Our corporate headquarters is located in Santa Clara, California, and consists of a building of approximately 129,000 square feet. In June 2016, we entered into a lease agreement for our new corporate headquarters in Milpitas, California with a term of 60 months which consists of approximately 19,000 square feet office space. In the same month, we signed a lease termination agreement for our current headquarters lease. We expect to complete the move of our corporate headquarters to Milpitas, California by September 2016. We also lease approximately 54,000 square feet of office, assembly facilities and warehouse in certain locations in Texas. Internationally, we lease approximately 111,000 square feet of facilities throughout Europe, Canada, Central America, South America, Africa and Asia regions, including offices in Singapore, Slovenia, Philippine Islands, India, Mexico, Brazil, South Africa, Ghana, Ivory Coast, Kenya, Nigeria, Algeria, France, Netherlands, Poland, Russia, Australia, Dubai, Saudi Arabia, Lebanon, China, and Thailand. In addition, we own approximately 108,000 square feet of facilities in Wellington, New Zealand and Lanarkshire, Scotland.

We maintain our facilities in good operating condition, and believe that they are suitable and adequate for our current and projected needs. We continuously review our anticipated requirements for facilities and may, from time to time, acquire additional facilities, expand existing facilities, or dispose of existing facilities or parts thereof, as we deem necessary.

For more information about our lease obligations, see "Note 12. Commitments and Contingencies" of the notes to consolidated financial statements, which are included in Item 8 in this Annual Report on Form 10-K.

Item 3. Legal Proceedings

We are subject from time to time to disputes with customers concerning our products and services. In May 2016, we received notification of a claim for $1.0 million in damages from a customer in Austria alleging that certain of our products were defective. We are continuing to investigate this claim, and at this time an estimate of the reasonably possible loss or range of loss cannot be made. In August 2016, we received a correspondence from a customer in Africa demanding that certain inventory aggregating $1.0 million be repurchased under the terms of an inventory management agreement that we believe has expired. We are continuing to investigate this demand, and at this time an estimate of the reasonably possible loss or range of loss cannot be made. We believe that we have numerous contractual and legal defenses to these disputes, which are in their early stages, and we intend to dispute them vigorously.

From time to time, we may be involved in various other legal claims and litigation that arise in the normal course of our operations. We are aggressively defending all current litigation matters. Although there can be no assurances and the outcome of these matters is currently not determinable, we currently believe that none of these claims or proceedings are likely to have a material adverse effect on our financial position. We expect to defend each of these disputes vigorously. There are many uncertainties associated with any litigation and these actions or other third-party claims against us may cause us to incur costly litigation and/or substantial settlement charges. As a result, our business, financial condition, results of operations, and cash flows could be adversely affected. The actual liability in any such matters may be materially different from our estimates, if any.

We record accruals for our outstanding legal proceedings, investigations or claims when it is probable that a liability will be incurred and the amount of loss can be reasonably estimated. We evaluate, at least on a quarterly basis, developments in legal proceedings, investigations or claims that could affect the amount of any accrual, as well as any developments that would result in a loss contingency to become both probable and reasonably estimable. We have not recorded any accrual for loss contingencies associated with such legal claims or litigation discussed above.

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

Overview of Business; Operating Environment and Key Factors Impacting Fiscal 2015 and 2016 Results

The following Management's Discussion and Analysis ("MD&A") is intended to help the reader understand our results of operations and financial condition. MD&A is provided as a supplement to, and should be read in conjunction with, our consolidated financial statements and the accompanying notes. In the discussion below, our fiscal year ending June 30, 2017 is referred to as "fiscal 2017 " or " 2017 "; our fiscal year ended July 1, 2016 is referred to as "fiscal 2016 " or " 2016 "; our fiscal year ended July 3, 2015 is referred to as "fiscal 2015 " or " 2015 "; and our fiscal year ended June 27, 2014 is referred to as "fiscal 2014 " or " 2014 ."

Overview

We generate revenue by designing, developing, manufacturing and supporting a range of wireless networking products, solutions and services for mobile and fixed communications service providers, private network operators, government agencies, transportation and utility companies, public safety agencies and broadcast system operators across the globe. Our products include point-to-point digital microwave transmission systems designed for first/last mile access, middle mile/backhaul, and long distance trunking applications. We also provide network management software solutions to enable operators to deploy, monitor and manage our systems, third party equipment such as antennas, routers, and multiplexers, necessary to build and deploy a wireless transmission network, and a full suite of turnkey support services.

We work continuously to improve our established brands and to create new products that meet our customers' evolving needs and preferences. Our fundamental business goal is to generate superior returns for our stockholders over the long term. We believe that increases in revenue, operating profits and earnings per share are the key measures of financial performance for our business.

Our strategic focus in fiscal 2017 will be to continue to accelerate innovation and optimize our product portfolio, improve costs and operational efficiencies, grow our revenue and create a sustainable, profitable business model. To do this, we continue to examine our products, markets, facilities, development programs, and operational flows to ensure we are focused on what we do well and what will differentiate us in the future. We will continue working to streamline management processes to attain the efficiency levels required by the markets in which we do business.

Although the general trend of increasing demand for bandwidth to support mobile networks applies in all markets, we expect to see quarter-to-quarter fluctuations within markets and with individual customers based on customers' past purchasing patterns. Seasonality is also a factor that impacts our business. Our fiscal third quarter revenue and orders have historically been lower than the revenue and orders in our second fiscal quarter because many of our customers utilize a significant portion of their capital budgets at the end of their fiscal years, which is typically the calendar year end and coincides with our second fiscal quarter. The majority of our customers begin a new fiscal year on January 1, and capital expenditures tend to be lower in an organization's first quarter than in its fourth quarter. We anticipate that this seasonality will continue. The seasonality between the second quarter and third quarter may be affected by a variety of additional factors, including changes in the global economy.

In line with industry trends, we expect to provide increased managed services, including network design, inventory management, final configuration and warehousing services, to certain customers in certain geographies. Our operating results may be impacted by providing these services to the extent that we may need to postpone the recognition of revenue and incur upfront and ongoing expenses that are not offset with additional revenue from product sales associated with these services until a future period.

Operations Review

The market for mobile backhaul continues to be our primary addressable market segment and, over the long term, the demand for increasing the backhaul capacity in our customers' networks continues to grow. In North America we supported long-term evolution ("LTE") deployments of our mobile operator customers, public safety network deployments for state and local governments, and private network implementations for utilities and other customers. Our international business was adversely affected in fiscal 2016 by constrained availability of U.S. dollars in countries with economies highly dependent on resource exports, particularly oil. This condition limited capital spending and slowed payments from customers in those locations. In international markets, our business continued to rely on a combination of customers increasing their capacity to handle subscriber growth, the ongoing build-out of some large 3G deployments, and the emergence of early stage LTE deployments. Our position continues to be to support our customers for LTE readiness and ensure that our technology roadmap is well aligned with evolving market requirements. We continue to

find that our strength in turnkey and after-sale support services is a differentiating factor that wins business for us and enables us to expand our business with existing customers in all markets. However, as disclosed above and in the "Risk Factors" section in Item 1A of this Annual Report on Form 10-K, a number of factors could prevent us from achieving our objectives, including ongoing pricing pressures attributable to competition and macroeconomic conditions in the geographic markets that we service.

Revenue

We manage our sales activities primarily on a geographic basis in North America and three international geographic regions: (1) Africa and Middle East, (2) Europe and Russia and (3) Latin America and Asia Pacific. Revenue by region for fiscal 2016, 2015 and 2014 and the related changes were shown in the table below:

Our revenue in North America decreased $27.8 million , or 18.1% , in fiscal 2016 compared with fiscal 2015 . While our order volume increased in North America compared to fiscal 2015, we experienced a shift in the mix of business away from wireless operator customers and toward private networks operated by governments and utilities. The decrease in the North America wireless operator customers revenue was due primarily to them reaching the end of their LTE network build cycle. In addition, orders from private networks generally have a longer cycle time from order placement to completion for revenue than orders from the wireless operators, owing to the larger degree of service content included with the private network projects. In fiscal 2016 we saw a decrease in revenue both from the lower volume of business with wireless operator customers and from the longer cycle time to revenue from the larger volume of business with private network customers. Revenue in North America increased $11.2 million , or 7.9% , in fiscal 2015 compared with fiscal 2014 . The increase in North America primarily resulted from increase of revenue from the government and utility markets, while revenue from network operator customers declined in fiscal 2015 compared with fiscal 2014.

Revenue in Africa and Middle East decreased $14.4 million , or 14.8% , in fiscal 2016 compared with fiscal 2015 . The fiscal 2016 decrease in revenue came from decreased sales volume to our private network customers in the Middle East and across several customers in Africa. Revenue with our major wireless operator customers in the region remained relatively low, and slightly down in fiscal 2016 compared to fiscal 2015. Revenue in Africa and Middle East decreased $11.8 million , or 10.8% , in fiscal 2015 compared with fiscal 2014 , reflecting network operator capital spending restraint in fiscal 2015 compared with fiscal 2014.

Revenue in Europe and Russia was down $15.5 million , or 42.9% , in fiscal 2016 compared with fiscal 2015 . The decrease came from lower sales to our large customers in the region compared with the same periods in fiscal 2015. Both the unfavorable currency exchange rate change on our U.S. dollar based prices and limited customer capital spending in the region contributed to lower revenue volume during fiscal 2016. Revenue in Europe and Russia remained approximately the same for fiscal 2015 compared with fiscal 2014.

Revenue in Latin America and Asia Pacific declined $9.6 million , or 19.4% , in fiscal 2016 compared with fiscal 2015, mostly due to lower product sales to several mid-size customers in Asia Pacific, partially offset by a large increase with one of our major customers in the region. The decrease was also attributable to a year-to-year reduction in sales to private network customers in Latin America. Revenue in Latin America and Asia Pacific declined $9.5 million , or 16.1% , in fiscal 2015 compared with fiscal 2014 , mostly due to lower product sales to our customers in Latin America.

Our revenue from product sales decreased $47.0 million , or 21.9% , in fiscal 2016 compared with fiscal 2015 . Product volumes were lower in all sectors, but the majority of the decrease was in North America and Europe. In North America this decline reflected fewer orders from wireless operators and the extended cycle time to complete large projects. In Europe, this decline reflected constrained capital spending mentioned above. Our service revenue decreased $20.1 million , or 16.6% , in fiscal 2016 compared with fiscal 2015 , due to reduced service activities in all sectors, but particularly in North America, Middle East and Africa.

Our revenue from product sales decreased $7.8 million , or 3.5% , in fiscal 2015 compared with fiscal 2014 . The decrease came primarily from weaker product sales in Africa and Latin America, offset in part by stronger product sales in North America, Europe and Asia. Our services revenue decreased $2.4 million , or 1.9% , in fiscal 2015 compared with fiscal 2014 , due to reduced service activities in Asia Pacific, Europe and Latin America, partially offset by increased service activities in Africa and North America.

During fiscal 2016 , the MTN Group in Africa accounted for 18% of our total revenue compared with 14% in fiscal 2015 and 17% in fiscal 2014 . We have entered into separate and distinct contracts with MTN Group as well as separate arrangements with various MTN Group subsidiaries. The loss of all or a substantial portion of MTN Group's business could adversely affect our results of operations, cash flows and financial position.

Gross Margin

Gross margin for fiscal 2016 decreased $19.0 million , or 23.5% , compared with fiscal 2015 , primarily due to decreased revenue volume across all business sectors during fiscal 2016, partially offset by reduced supply chain costs compared with fiscal 2015 . Gross margin as a percentage of revenue decreased in fiscal 2016 compared with fiscal 2015 primarily due to the large drop in revenue volume relative to supply chain costs during the year. Product margin as a percentage of product revenue decreased from fiscal 2015 primarily due to supply chain costs being absorbed by a substantially smaller volume of product sales during the year and an increase in inventory write-down of $2.9 million . Service margin as a percentage of service revenue declined primarily due to a less profitable service business in international markets.

Gross margin for fiscal 2015 decreased $4.5 million , or 5.3% , compared with fiscal 2014 , primarily due to decreased profitability in Africa, Middle East, Europe and Latin America and a $2.5 million increase in foreign exchange loss, partially offset by improved profitability in North America and Asia along with reduced supply chain costs compared with fiscal 2014. Gross margin as a percentage of revenue decreased in fiscal 2015 compared with fiscal 2014 primarily due to lower profitability in Africa, Middle East, Europe and Latin America and increased foreign exchange losses compared with fiscal 2014, partially offset by higher gross margin rates in North America and Asia. Product margin as a percentage of product revenue increased over fiscal 2014 primarily to a greater portion of the overall business coming from North America along with improved pricing in that market, and better pricing on sales in Asia. Service margin as a percentage of service revenue declined primarily due to a less profitable service business in international markets.

Research and Development Expenses

Our R&D expenses decreased $4.6 million , or 18.0% , in fiscal 2016 compared with fiscal 2015 . The decrease in R&D expenses was primarily due to a $4.4 million reduction in personnel and related expenses due to the restructuring programs implemented, and $1.8 million facility expense reassigned to restructuring accounts. The decreases were partially offset by a $1.7 million increase in professional services and material spending for new products. We continue to invest in new product features, new functionality and lower cost platforms that we believe will enable our product lines to retain their technology leads in a cost effective manner.

Our R&D expenses decreased $10.1 million , or 28.5% , in fiscal 2015 compared with fiscal 2014 . The decrease in R&D expenses was primarily due to a $7.2 million reduction in personnel and related expenses, a $1.2 million decrease in new product development costs, a $2.0 million decrease in facility expense, a $0.2 million decrease in travel expense and a $0.2 million decrease in share-based compensation expenses. These decreases were primarily due to restructuring initiatives implemented in Santa Clara, California.

Selling and Administrative Expenses

Our selling and administrative expenses decreased $10.1 million , or 13.3% , in fiscal 2016 compared with fiscal 2015 . The decrease was primarily due to a $3.8 million decrease in personnel and related expenses, a $6.5 million reduction in professional fees primarily associated with accounting, IT, legal, and marketing consulting services, a $1.4 million decrease in sales commission and incentive compensation, and a $0.4 million decrease in share-based compensation expenses. The decreases were partially offset by a $1.9 million increase in professional fees primarily associated with process improvements, and a $0.6 million increase in bad debt expenses. We will continue to seek ways to improve our operating efficiency in fiscal 2017.

Our selling and administrative expenses decreased $12.8 million , or 14.4% , in fiscal 2015 compared with fiscal 2014 . The decrease was due primarily to a $7.1 million decrease in personnel and related expenses, a $1.8 million decrease in IT consulting expenses as result of the completion of our ERP system implementation, a $1.7 million reduction in travel expenses, a $3.6 million decrease in sales commission and incentive compensation, and a $1.0 million decrease in share-based compensation expenses resulting from employee terminations and full vesting of prior stock awards. The decreases were partially offset by a $3.4 million increase in professional fees.

Restructuring Charges

During the fourth quarter of fiscal 2016, we initiated a restructuring plan (the "Fiscal 2016-2017 Plan") to streamline our operations and align expense with current revenue levels. Activities under the Fiscal 2016-2017 Plan primarily include reductions in force in marketing, selling and general and administrative functions across the Company.

During the third quarter of fiscal 2015, with the intent to bring our operational cost structure in line with the changing dynamics of the microwave radio and telecommunications markets, we initiated a restructuring plan ("the Fiscal 2015-2016 Plan") to lower fixed overhead costs and operating expenses and to preserve cash flow. Activities under the Fiscal 2015-2016 Plan primarily include reductions in force across the Company, but primarily in operations outside the United States.

During the third quarter of fiscal 2014, in line with the decrease in revenue that we experienced and our reduced forecast for the immediate future, we initiated a restructuring plan ("the Fiscal 2014-2015 Plan") to reduce our operating costs, primarily in North America, Europe and Asia. Activities under the Fiscal 2014-2015 Plan primarily include reductions in force and additional facility downsizing of our Santa Clara, California headquarters.

During the fourth quarter of fiscal 2013, we initiated a restructuring plan (the "Fiscal 2013-2014 Plan") that was intended to reduce our operating expenses primarily in North America, Europe and Asia. Activities under the Fiscal 2013-2014 Plan included reductions in force and the downsizing of our Santa Clara, California headquarters and certain international field offices.

Our restructuring charges by plan for fiscal 2016, 2015 and 2014 are summarized in the table below:

Our restructuring expenses consisted primarily of severance and related benefit charges, facilities costs related to obligations under non-cancelable leases for facilities that we ceased to use, and lease termination charges. During June 2016, we entered into a lease termination agreement for our current headquarters lease in Santa Clara, California. We ceased using parts of the building under the Fiscal 2014-2015 Plan and under the Fiscal 2013-2014 Plan, and recognized lease impairment liabilities in fiscal 2015 and 2014, respectively.

Restructuring charges for fiscal 2016 included $2.5 million employee severance and benefits costs primarily related to the Fiscal 2016-2017 Plan and the Fiscal 2015-2016 Plan, a $1.9 million lease termination payable, offset by a $1.2 million deferred rent liability write-off and a net decrease of $0.7 million lease impairment liabilities both resulted from the termination of our Santa Clara headquarters building. Restructuring charges for fiscal 2015 included a $2.9 million employee termination charge primarily related to the Fiscal 2015-2016 Plan, a $1.4 million facility charge related to ceasing to use portion of our Santa Clara headquarters building and a $0.6 million Slovenia government fund penalty charge related to the workforce reduction. Restructuring charges for fiscal 2014 included a $4.8 million facilities charge primarily related to ceasing to use a portion of our Santa Clara headquarters building and a $6.4 million employee termination charge related to our Fiscal 2014-2015 Plan and Fiscal 2013-2014 Plan.

We intend to substantially complete the remaining restructuring activities under all Plans by the end of fiscal 2017.

Interest Income, Interest Expense and Other Expense

Interest income reflected interest earned on our cash equivalents which were comprised of money market funds and certificates of deposit.

Interest expense was primarily related to interest associated with borrowings and term loans under the Silicon Valley Bank ("SVB") Credit Facility and discounts on customer letters of credit.

Other expense related to the foreign exchange loss on a dividend declared by our Nigeria entity (a partnership for U.S. tax purpose) to Aviat U.S. entity which was caused by a significant devaluation of the Nigerian Naira in June 2016.

Income Taxes

Our income tax expense (benefit) from continuing operations was $1.6 million of expense for fiscal 2016 compared to $1.3 million of benefit for fiscal 2015 and $1.5 million of expense for fiscal 2014. The difference between our income tax expense (benefit) from continuing operations and income tax expense at the statutory rate of 35% was primarily attributable to losses in tax jurisdictions in which we cannot recognize a tax benefit and increase in foreign withholding taxes. During fiscal 2015, we released approximately $4.4 million of its deferred tax valuation allowance in jurisdictions where management believed the utilization of deferred tax assets was more likely than not based on the weighting of positive and negative evidence which resulted in an income tax benefit in fiscal 2015.

We are subject to income taxes in the U.S. and numerous foreign jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes and recording the related assets and liabilities. In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is uncertain.

Income from Discontinued Operations

Our discontinued operations consisted of the WiMAX business, which was sold to EION Networks, Inc. ("EION") on September 2, 2011. We completed the business transition with EION in fiscal 2012. The income recognized in fiscal 2015 was primarily due to a $0.1 million write-off of accrued liabilities due to EION. The income recognized in fiscal 2016 and fiscal 2014 was primarily due to recovery of certain WiMAX customer receivables that were previously written down.

Liquidity, Capital Resources and Financial Strategies

As of July 1, 2016 , our total cash and cash equivalents and short-term investments totaled $30.7 million . Approximately $18.5 million , or 60.2% , was held by entities domiciled in the United States. The remaining balance of $12.2 million, or 39.8% , was held by entities outside the United States. In June of 2016, the Nigeria Central Bank allowed the Naira to float freely after being fixed at approximately 197 Naira to one U.S. dollar. This event caused a devaluation in the Naira to approximately 280 Naira to one U.S. dollar and reduced our Nigerian cash balance by approximately $1.5 million. Of the amount of cash and cash equivalents held by our foreign subsidiaries at July 1, 2016 , $8.2 million was held in jurisdictions where our undistributed earnings are indefinitely reinvested, and if repatriated, would be subject to U.S. taxes.

Operating Activities

Cash used in operating activities is net loss adjusted for certain non-cash items and changes in assets and liabilities. Net cash used in operating activities was $0.1 million for fiscal 2016, $9.0 million for fiscal 2015 and $29.3 million for fiscal 2014.

For fiscal 2016 compared to fiscal 2015, the  $8.8 million  decrease in cash used operating activities was due to changes in working capital and adjustments for non-cash items offset by a higher net loss. The adjustments for non-cash items were higher than fiscal 2015 due primarily to deferred income taxes, and inventory and customer service inventory write-downs, partially offset by lower depreciation and amortization of property, plant and equipment, amortization of identifiable intangible assets and share-based compensation.

Changes in assets and liabilities for fiscal 2016 compared to fiscal 2015 included a decrease in accounts receivable, unbilled costs, accounts payable, advance payments and unearned income and accrued expenses. These decreases were offset by an increase in inventories and other assets and liabilities. In addition, we used $3.3 million in cash during fiscal 2016 on expenses related to restructuring liabilities. Our accounts receivable and unbilled costs fluctuate from period to period depending on the amount and timing of billing activity and cash collections. The change in accounts payable and accrued expenses were due to timing of additional liabilities and payments in general. The change in advance payments and unearned income were due to timing of payment from customers and revenue recognition. Inventory balance fluctuates depending on demand.

For fiscal 2015 compared to fiscal 2014, the  $20.3 million  decrease in cash used in operating activities was due to lower net loss and adjustment for non-cash items, offset by changes in working capital.

Investing Activities

Investing cash flows consist primarily of capital expenditures. Net cash used in investing activities was $1.8 million for fiscal year 2016, $3.7 million for fiscal 2015 and $9.4 million for fiscal 2014.

For fiscal 2017, we expect to spend approximately $3.0 million  for capital expenditures, primarily on equipment for development and manufacturing of new products and to support customer managed services.

Financing Activities

Financing cash flows consist primarily of proceeds and repayments of short-term debt and proceeds from sale of share of common stock through employee equity plans. Net cash provided by (used in) financing activities was $13 thousand for fiscal year 2016, $2.9 million for fiscal 2015 and $(2.8) million for fiscal 2014.

As of July 1, 2016 , our principal sources of liquidity consisted of the $30.7 million in cash, cash equivalents and short-term investments, $4.8 million of available credit under our $30.0 million credit facility with Silicon Valley Bank ("SVB") which expires on June 30, 2018 , and future collections of receivables from customers. We regularly require letters of credit from some customers and, from time to time, these letters of credit are discounted without recourse shortly after shipment occurs in order to meet immediate liquidity requirements and to reduce our credit and sovereign risk. Historically our primary sources of liquidity have been cash flows from operations and credit facilities.

We believe that our existing cash and cash equivalents, the available line of credit under the SVB Credit Facility (as defined below) and future cash collections from customers will be sufficient to provide for our anticipated requirements for working capital and capital expenditures for at least the next 12 months. There can be no assurance, however, that our business will generate cash flow from operations, we will be in compliance with the quarterly financial covenants contained in the SVB Credit Facility, or that anticipated operational improvements will be achieved. If we are not in compliance with the financial covenants, the availability of our credit facility is not certain or may be diminished. Over the longer term, if we are unable to maintain cash balances or generate sufficient cash flow from operations to service our obligations that may arise in the future, we may be required to sell assets, reduce capital expenditures, or obtain financing. If we need to obtain additional financing, we cannot be assured that it will be available on favorable terms, or at all. Our ability to make scheduled principal payments or pay interest on or refinance any future indebtedness depends on our future performance and financial results, which, to a certain extent, are subject to general conditions in or affecting the microwave communications market and to general economic, political, financial, competitive, legislative and regulatory factors beyond our control.

Available Credit Facility, Borrowings and Repayment of Debt

On March 28, 2014, we entered into a Second Amended and Restated Loan Agreement with SVB (the "SVB Credit Facility"). The SVB Credit Facility was amended on September 25, 2014, October 30, 2014 and December 2, 2014 to provide for extensions to the deadline for preparing and filing our fiscal 2014 financial statements with the SEC. On February 27, 2015, the SVB Credit Facility was further amended to provide for certain amendments to the financial covenants, borrowing base and an early termination fee if the SVB Credit Facility is terminated prior to its expiration. In March 2016, we amended the SVB Credit Facility to amend financial covenants and to reduce the maximum borrowing capacity from $40.0 million to $30.0 million . In June 2016, we amended the SVB Credit Facility to amend the minimum Earnings before Interest, Tax, Depreciation and Amortization ("EBITDA") covenant; to create a new sub-limit for letters of credit issued under the revolving credit facility of $12.0 million ; to reduce the advance rate applicable to Singapore Borrower's eligible accounts in the calculation of the borrowing base of the revolving credit facility; to increase the interest rate margins applicable to revolving loans made to Singapore Borrower by 2.00% above the applicable margin; and to extend the facility maturity date to June 30, 2018. The SVB Credit Facility carries an interest rate computed at the daily prime rate as published in the Wall Street Journal plus a spread of 0.50% to 1.50% , with such spread determined based on our adjusted quick ratio. During fiscal 2016 , the weighted average interest rate on our outstanding loan was 3.88% . As of July 1, 2016 and July 3, 2015 , our outstanding debt balance under the SVB Credit Facility was $9.0 million in each fiscal year, and the interest rate was 4.00% and 3.75% respectively.

The SVB Credit Facility provides for a committed amount of up to $30.0 million , with a $30.0 million sublimit that can be borrowed by our Singapore subsidiary. Borrowings that may be advanced under the SVB Credit Facility at the lesser of $30.0 million or a borrowing base equal to a specified percentage of the value of eligible accounts receivable and U.S. unbilled accounts of the Company, subject to certain reserves and eligibility criteria. The SVB Credit Facility can also be utilized to issue letters of credit with a $12.0 million sublimit. If the SVB Credit Facility is terminated by us in certain circumstances prior to its expiration, we are subject to an early termination fee equal to 1% of

the revolving line. As of July 1, 2016 , available credit under the SVB Credit Facility was $4.8 million reflecting the calculated borrowing base of $20.0 million less existing borrowings of $9.0 million and outstanding letters of credit of $6.2 million .

The SVB Credit Facility contains quarterly financial covenants including minimum adjusted quick ratio and minimum profitability (EBITDA) requirements. In the event our adjusted quick ratio falls below a certain level, cash received in our accounts with SVB may be directly applied to reduce outstanding obligations under the SVB Credit Facility. The SVB Credit Facility also imposes certain restrictions on our ability to dispose of assets, permit a change in control, merge or consolidate, make acquisitions, incur indebtedness, grant liens, make investments, make certain restricted payments and enter into transactions with affiliates under certain circumstances. Certain of our assets, including accounts receivable, inventory, and equipment, are pledged as collateral for the SVB Credit Facility. Upon an event of default, outstanding obligations would be immediately due and payable. Under certain circumstances, a default interest rate will apply on all obligations during the existence of an event of default at a per annum rate of interest equal to 2.00% above the applicable interest rate.

As of July 1, 2016 , we were in compliance with the quarterly financial covenants contained in the SVB Credit Facility, as amended. However, as a result of uncertainty on our ability to continue to meet the financial covenants in the future and the fact that the SVB Credit Facility contains subjective acceleration clauses that could be triggered by the lender, the $9.0 million borrowing was classified as a current liability as of July 1, 2016 and July 3, 2015 .

Restructuring Payments

We have a liability for restructuring activities totaling $4.8 million as of July 1, 2016 , of which $3.9 million is classified as current liability and expected to be paid in cash over the next 12 months. We expect to fund these future payments with available cash and cash equivalents and short-term investments.

Contractual Obligations

As of July 1, 2016 , cash payments due under our contractual obligations were estimated as follows:

 ___________________________

Commercial Commitments

We have entered into commercial commitments in the normal course of business including surety bonds, standby letters of credit and other arrangements with financial institutions and insurers primarily relating to the guarantee of future performance on certain tenders and contracts to provide products and services to customers. As of July 1, 2016 , we had commercial commitments on outstanding surety bonds and standby letters of credit as follows:

As we have not historically had to pay out on any of our performance guarantees, the outstanding commercial commitments have not been recorded in our consolidated balance sheet.

Off-Balance Sheet Arrangements

In accordance with the definition under SEC rules (Item 303(a) (4) (ii) of Regulation S-K), any of the following qualify as off-balance sheet arrangements:

Currently we are not participating in transactions that generate relationships with unconsolidated entities or financial partnerships, including variable interest entities, and we do not have any material retained or contingent interest in assets as defined above. As of July 1, 2016 , we did not have material financial guarantees or other contractual commitments that are reasonably likely to adversely affect liquidity. In addition, we are not currently a party to any related party transactions that materially affect our results of operations, cash flows or financial condition.

Due to the downsizing of certain of our operations pursuant to restructuring plans or otherwise, some properties leased by us have been sublet to third parties. In the event any of these third parties vacate any of these premises, we would be legally obligated under master lease arrangements. We believe that the financial risk of default by such sublessors is not likely to be individually or in the aggregate material to our financial position, results of operations or cash flows.

Financial Risk Management

In the normal course of doing business, we are exposed to the risks associated with foreign currency exchange rates and changes in interest rates. We employ established policies and procedures governing the use of financial instruments to manage our exposure to such risks.

Exchange Rate Risk

We conduct business globally in numerous currencies and are therefore exposed to foreign currency risks. We use derivative instruments to reduce the volatility of earnings and cash flows associated with changes in foreign currency exchange rates. We do not hold or issue derivatives for trading purposes or make speculative investments in foreign currencies.

We use foreign exchange forward contracts to hedge forecasted foreign currency transactions relating to forecasted sales and purchase transactions. Prior to the fourth quarter of fiscal 2015, these derivatives were designated as cash flow hedges and are carried at fair value. The effective portion of the gain or loss was initially reported as a component of accumulated other comprehensive income (loss), and upon occurrence of the forecasted transaction, was subsequently reclassified into the income or expense line item to which the hedged transaction relates. Beginning the fourth quarter of fiscal 2015, we no longer prepared contemporaneous documentation of hedges therefore the foreign exchange hedges no longer qualified as cash flow hedge. The changes in fair value related to the hedges were recorded in income or expenses line items on our statements of operations. We also enter into foreign exchange forward contracts to mitigate the change in fair value of specific non-functional currency assets and liabilities on the balance sheet. All balance sheet hedges are marked to market through earnings every period. Changes in the fair value of these derivatives are largely offset by re-measurement of the underlying assets and liabilities.

As of July 1, 2016 , we had foreign currency forward contracts outstanding with a total notional amount of $1.7 million consisting of two different currencies. The following is a summary of the gross notional amount of our outstanding contracts grouped by the underlying foreign currency as of July 1, 2016 :

Net foreign exchange loss recorded in our consolidated statements of operations during fiscal 2016, 2015 and 2014 was as follows:

A 10% adverse change in currency exchange rates for our foreign currency derivatives held as of July 1, 2016 would have an impact of approximately $0.2 million on the fair value of such instruments. Certain of our international business was transacted in non-U.S. dollar currency. As discussed above, we utilize foreign currency hedging instruments to minimize the currency risk of international transactions. The impact of translating the assets and liabilities of foreign operations to U.S. dollars is included as a component of stockholders' equity. As of July 1, 2016 and July 3, 2015 , the cumulative translation adjustment decreased our stockholders' equity by $ 11.2 million and $ 8.7 million , respectively.

In June of 2016, the Nigeria Central Bank allowed the Naira to float freely after being fixed at approximately 197 Naira to one U.S. dollar. This event caused a devaluation in the Naira to approximately 280 Naira to one U.S. dollar resulting in the year over year losses in foreign exchange and cumulative translation adjustments for our Nigeria transactions.

During fiscal 2015 the company experienced increased volatility in foreign currency markets, resulting in the increased year over year losses in foreign exchange and cumulative translation adjustments, particularly in countries where there is no available market to hedge the local currency. 

Interest Rate Risk

Our exposure to market risk for changes in interest rates relates primarily to our cash equivalents and borrowings under our credit facility.

Exposure on Cash Equivalents

We had $ 30.5 million in total cash and cash equivalents as of July 1, 2016 . Cash equivalents totaled $18.8 million as of July 1, 2016 and were comprised of money market funds and certificates of deposit. Cash equivalents have been recorded at fair value on our balance sheet.

We do not use derivative financial instruments in our short-term investment portfolio. We invest in high-credit quality issues and, by policy, limit the amount of credit exposure to any one issuer and country. The portfolio includes only marketable securities with active secondary or resale markets to ensure portfolio liquidity. The portfolio is also diversified by maturity to ensure that funds are readily available as needed to meet our liquidity needs. This policy reduces the potential need to sell securities in order to meet liquidity needs and therefore the potential effect of changing market rates on the value of securities sold.

The primary objective of our short-term investment activities is to preserve principal while maximizing yields, without significantly increasing risk. Our cash equivalents earn interest at fixed rates; therefore, changes in interest rates will not generate a gain or loss on these investments unless they are sold prior to maturity. Actual gains and losses due to the sale of our investments prior to maturity have been immaterial. The weighted average days to maturity for cash equivalents held as of July 1, 2016 was 348 days, and these investments had an average yield of 6.77%  per annum. A 10% change in interest rates on our cash and cash equivalents is not expected to have a material impact on our financial position, results of operations or cash flows.

Exposure on Borrowings

During fiscal 2016 , we had $9.0 million of demand borrowings outstanding under our credit facility that incurred interest at the prime rate or prime rate plus a spread of 0.50% to 1.50% , with such spread determined based on our adjusted quick ratio. During fiscal 2016 , our weighted average interest rate was 3.88% and we recorded total interest expense of less than $0.1million on these borrowings.

A 10% change in interest rates on the current borrowings or on future borrowings is not expected to have a material impact on our financial position, results of operations or cash flows since interest on our borrowings is not material to our overall financial position.

Critical Accounting Estimates

Our consolidated financial statements are prepared in accordance with U.S. GAAP. These accounting principles require us to make certain estimates, judgments and assumptions. We believe that the estimates, judgments and assumptions upon which we rely are reasonable based upon information available to us.

These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities as of the date of the consolidated financial statements as well as the reported amounts of revenues and expenses during the periods presented. To the extent there are material differences between these estimates, judgments or assumptions and actual results, our financial statements will be affected.

The accounting policies that reflect our more significant estimates, judgments and assumptions and which we believe are the most critical to aid in fully understanding and evaluating our reported financial results include the following:

In some cases, the accounting treatment of a particular transaction is specifically dictated by U.S. GAAP and does not require management's judgment in its application. There are also areas in which management's judgment in selecting

among available alternatives would not produce a materially different result. Our senior management has reviewed these critical accounting policies and related disclosures with the Audit Committee of the Board of Directors.

The following is not intended to be a comprehensive list of all of our accounting policies or estimates. Our significant accounting policies are more fully described in "Note 1. The Company and Summary of Significant Accounting Policies" in the notes to consolidated financial statements. In preparing our financial statements and accounting for the underlying transactions and balances, we apply those accounting policies. We consider the estimates discussed below as critical to an understanding of our financial statements because their application places the most significant demands on our judgment, with financial reporting results relying on estimates about the effect of matters that are inherently uncertain.

Besides estimates that meet the "critical" accounting estimate criteria, we make many other accounting estimates in preparing our financial statements and related disclosures. All estimates, whether or not deemed critical, affect reported amounts of assets, liabilities, revenue and expenses as well as disclosures of contingent assets and liabilities. Estimates are based on experience and other information available prior to the issuance of the financial statements. Materially different results can occur as circumstances change and additional information becomes known, including for estimates that we do not deem "critical."

Revenue Recognition and Valuation of Accounts Receivable

We generate substantially all of our revenue from the sales or licensing of our microwave radio and wireless access systems, network management software, and professional services including installation, commissioning, maintenance and support services and training. Maintenance and support services are generally offered to our customers over a specified period of time and from sales and subsequent renewals of maintenance and support contracts. We recognize the related revenue ratably over the maintenance or service period. Professional services revenue consists of fees we earn related to consulting and educational services. We recognize revenue from professional services as the services are performed or upon written acceptance from customers, if applicable, assuming all other conditions for revenue recognition noted above have been met. Principal customers for our products and services include domestic and international wireless/mobile service providers, original equipment manufacturers, resellers, system integrators, as well as private network users such as public safety agencies, government institutions, and utility, pipeline, railroad and other industrial enterprises that operate broadband wireless networks. Our customers generally purchase a combination of our products and services as part of a multiple element arrangement. Our assessment of which revenue recognition guidance is appropriate to account for each element in an arrangement can involve significant judgment. This assessment has a significant impact on the amount and timing of revenue recognition.

Revenue is recognized when all of the following criteria have been met:

We often enter into multiple contractual agreements with the same customer. Such agreements are reviewed to determine whether they should be evaluated as one arrangement. If an arrangement, other than a long-term contract, requires the delivery or performance of multiple deliverables or elements, we determine whether the individual elements represent "separate units of accounting". The determination as to whether multiple contractual agreements should be evaluated as one arrangement and the identification of units of accounting in an arrangement requires significant judgment and impacts the amount of product and service revenue recognized in a given period.

In accordance with Financial Accounting Standards Board Accounting Standards Codification("ASC") 605-25, Revenue Recognition - Multiple-Element Arrangements, based on the terms and conditions of the product arrangements, we believe that our products and services can be accounted for separately as our products and services have value to our customers on a stand-alone basis. Accordingly, the arrangement consideration is allocated among deliverables based on their relative selling price. We generally determine relative selling price using estimated selling price ("ESP"). Revenue from each deliverable is recognized when all requirements are met for that specific deliverable.

There is generally no customer right of return in our sales agreements. The sequence for typical multiple-element arrangements is as follows: we deliver our products, perform installation services and then provide post-contract support services.

The selling price for each element is based upon the following selling price hierarchy: Vendor-specific objective evidence ("VSOE") if available, third party evidence ("TPE") if VSOE is not available or ESP if neither VSOE nor TPE are available. Generally, we are not able to determine TPE because our go-to-market strategy differs from that of our peers and our offerings contain a significant level of differentiation such that the comparable pricing of products with similar functionality cannot be obtained. In determining ESP, we apply significant judgment as we weigh a variety of factors including our pricing policies, internal costs and gross margin objectives, method of distribution, information gathered from experience in customer negotiations, market research and information, recent technological trends, competitive landscape and geographies. The determination of ESP is approved by our management taking into consideration our pricing strategy. We regularly review VSOE, TPE and ESP and maintain internal controls over the establishment and updates of these estimates. We do not expect a material impact in future periods from changes in VSOE, TPE or ESP.

Revenues related to long-term contracts for customized network solutions are recognized using the percentage-of-completion method. In using the percentage-of-completion method, we generally apply the cost-to-cost method of accounting where sales and profits are recorded based on the ratio of costs incurred to estimated total costs at completion. Contracts are combined when specific aggregation criteria are met including when the contracts are in substance an arrangement to perform a single project with a customer; the contracts are negotiated as a package in the same economic environment with an overall profit objective; the contracts require interrelated activities with common costs that cannot be separately identified with, or reasonably allocated to the elements, phases or units of output and the contracts are performed concurrently or in a continuous sequence under the same project management at the same location or at different locations in the same general vicinity. Recognition of profit on long-term contracts requires estimates of the total contract value, the total cost at completion and the measurement of progress towards completion. Significant judgment is required when estimating total contract costs and progress to completion on the arrangements as well as whether a loss is expected to be incurred on the contract. Amounts representing contract change orders, claims or other items are included in sales only when they can be reliably estimated and realization is probable. When adjustments in contract value or estimated costs are determined, any changes from prior estimates are reflected in earnings in the current period. Anticipated losses on contracts or programs in progress are charged to earnings when identified.

We reserve for estimated product returns as an offset to revenue or deferred revenue based primarily on historical trends. Actual product returns may be different than what was estimated. These factors and unanticipated changes in the economic and industry environment could make actual results differ from our return estimates.

Accounts receivable is presented net of allowance for estimated uncollectible accounts to reflect any loss anticipated on the collection of accounts receivable balances. U nbilled amounts include amounts associated with percentage-of-completion accounting and other earned revenues not currently billable due to contractual provisions. We calculate the allowance for doubtful accounts based on our history of write-offs, level of past due accounts and the economic status of the customers. We regularly review the adequacy of these allowances by considering internal factors such as historical experience, credit quality and age of the receivable balances as well as external factors such as economic conditions that may affect a customer's ability to pay and their expected default frequency rates, which are published by major third-party credit-rating agencies and are generally updated on a quarterly basis. If a major customer's creditworthiness deteriorates, actual defaults are higher than our historical experience, or other circumstances arise, then our estimates of the recoverability of amounts due to us could be overstated, and additional allowances could be required, which could have an adverse impact on our operating results.

Inventory Valuation and Provisions for Excess and Obsolete Losses

Our inventories have been valued at the lower of cost or market. We balance the need to maintain prudent inventory levels to ensure competitive delivery performance with the risk of excess or obsolete inventory due to changing technology and customer requirements, and new product introductions. The manufacturing of our products is handled primarily by contract manufacturers. Our contract manufacturers procure components and manufacture our products based on our forecast of product demand. We regularly review inventory quantities on hand and record a provision for excess and obsolete inventory based primarily on our estimated forecast of product demand, the stage of the product life cycle, anticipated end of product life and production requirements. Several factors may influence the sale and use of our inventories, including decisions to exit a product line, technological change, new product development and competing product offerings. These factors could result in a change in the amount of obsolete inventory quantities on

hand. Additionally, our estimates of future product demand may prove to be inaccurate, in which case the provision required for excess and obsolete inventory may be overstated or understated. In the future, if we determine that our inventory is overvalued, we would be required to recognize such costs in cost of product sales and services in our consolidated statement of operations at the time of such determination. In the case of goods which have been written down below cost at the close of a fiscal quarter, such reduced amount is considered the new lower cost basis for subsequent accounting purposes, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. We did not make any material changes in the valuation methodology during the past three fiscal years.

Our customer service inventories are stated at the lower of cost or market. We carry service parts because we generally provide product warranty for 12 to 36 months and earn revenue by providing enhanced and extended warranty and repair service during and beyond this warranty period. Customer service inventories consist of both component parts, which are primarily used to repair defective units, and finished units, which are provided for customer use permanently or on a temporary basis while the defective unit is being repaired. We record adjustments to reduce the carrying value of customer service inventories to their net realizable value. Factors influencing these adjustments include product life cycles, end of service life plans and volume of enhanced or extended warranty service contracts. Estimates of net realizable value involve significant estimates and judgments about the future, and revisions would be required if these factors differ from our estimates.

Impairment of Long-Lived Assets

We evaluate long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. Impairment is considered to exist if the total estimated future cash flows on an undiscounted basis are less than the carrying amount of the assets. If impairment exists, the impairment loss is measured and recorded based on discounted estimated future cash flows. In estimating future cash flows, assets are grouped at the lowest levels for which there are identifiable cash flows that are largely independent of cash flows from other asset groups.

Our estimate of future cash flows is based upon, among other things, certain assumptions about expected future operating performance, growth rates and other factors. The actual cash flows realized from these assets may vary significantly from our estimates due to increased competition, changes in technology, fluctuations in demand, consolidation of our customers, reductions in average selling prices and other factors. Assumptions underlying future cash flow estimates are therefore subject to significant risks and uncertainties.

Income Taxes and Tax Valuation Allowances

We record the estimated future tax effects of temporary differences between the tax basis of assets and liabilities of amounts reported in our consolidated balance sheet, as well as operating loss and tax credit carryforwards. Significant judgment is required in evaluating our uncertain tax positions and determining our provision for income taxes. Although we believe our reserves are reasonable, no assurance can be given that the final tax outcome of these matters will not be different from that which is reflected in our historical income tax provisions and accruals. We adjust these reserves in light of changing facts and circumstances, such as the opening and closing of a tax audit or the refinement of an estimate. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences may result in an increase or decrease to our tax provision in a subsequent period in which such determination is made.

We record deferred taxes by applying enacted statutory tax rates to the respective jurisdictions and follow specific and detailed guidelines in each tax jurisdiction regarding the recoverability of any tax assets recorded on the balance sheet and provide necessary valuation allowances as required. Future realization of deferred tax assets ultimately depends on meeting certain criteria in ASC 740, Income Taxes . One of the major criteria is the existence of sufficient taxable income of the appropriate character (for example, ordinary income or capital gain) within the carryback or carryforward periods available under the tax law. We regularly review our deferred tax assets for recoverability based on historical taxable income, projected future taxable income, the expected timing of the reversals of existing temporary differences and tax planning strategies. Our judgments regarding future profitability may change due to many factors, including future market conditions and our ability to successfully execute our business plans and/or tax planning strategies. Should there be a change in our ability to recover our deferred tax assets, our tax provision would increase or decrease in the period in which the assessment is changed.

The accounting estimates related to the liability for uncertain tax position require us to make judgments regarding the sustainability of each uncertain tax position based on its technical merits. It is inherently difficult and subjective to estimate our reserves for the uncertain tax positions. Although we believe our estimates are reasonable, no assurance can

be given that the final tax outcome of these matters will be same as these estimates. These estimates are updated quarterly based on factors such as change in facts or circumstances, changes in tax law, new audit activity, and effectively settled issues.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

Aviat Networks, Inc.

Santa Clara, California:

We have audited the accompanying consolidated balance sheets of Aviat Networks, Inc. as of July 1, 2016 and July 3, 2015, and the related consolidated statements of operations, comprehensive loss , equity and cash flows for the years ended July 1, 2016 and July 3, 2015. In connection with our audits of the financial statements, we have also audited the financial statement schedule - Valuation and Qualifying Accounts as of and for the years ended July 1, 2016 and July 3, 2015 listed in the Index at Item 15(a)(2). These financial statements and schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and schedule. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Aviat Networks, Inc. as of July 1, 2016 and July 3, 2015 and the results of its operations and its cash flows for the years ended July 1, 2016 and July 3, 2015, in conformity with accounting principles generally accepted in the United States of America.

Also, in our opinion, the financial statement schedule - Valuation and Qualifying Accounts as of and for the years ended July 1, 2016 and July 3, 2015, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly in all material respects the information set forth therein.
