MARKET INFORMATION
 
General Industry Background
 
Plantronics operates predominantly in the electronics industry and focuses on the design, manufacture, and distribution of headsets for business and consumer applications, and other specialty products for the hearing impaired.  We develop enhanced communication products for offices and contact centers, mobile anddevices, cordless phones, and computers and gaming consoles.  We offer our products under two brands – Plantronics and Clarity.

The proliferation of voice communications applications across much of people's daily lives make communications headsets a key driver of efficiency, ergonomic comfort, and safety for our users.  The increased adoption of new and existing technologies, such as UC, Bluetooth,, Voice over Internet Protocol ("VoIP"), Digital Signal Processing ("DSP"), and Digital Enhanced Cordless Telecommunications (“DECT™”), each of which is described below, has contributed to increased demand for our headsets and audio solutions:

UC is the integration of voice, data, and video-based communications systems enhanced with software applications and IP networks.  It may include the integration of devices and media associated with a variety of business workflows and applications, including e-mail, instant messaging, presence, audio, video conferencing, and unified messaging.  UC seeks to provide seamless connectivity and user experience for enterprise workers regardless of their location and environment, improving overall business efficiency and providing more effective collaboration among an increasingly distributed workforce.  

Bluetooth wireless technology is a short-range communications protocol intended to replace the cables connecting portable and/or fixed devices while maintaining high levels of security.  The key features of Bluetooth technology are ubiquity, low power, and low cost.  The Bluetooth specification defines a uniform structure for a wide range of devices to connect and communicate with each other.  Bluetooth standard has achieved global acceptance such that any Bluetooth enabled device, almost anywhere in the world, can connect to other Bluetooth enabled devices in proximity.

VoIP is a technology that allows a person to communicate using a broadband Internet connection instead of a regular (or analog) telephone line.  VoIP converts the voice signal into a digital signal that travels over the Internet or other packet-switched networks and then converts it back at the other end so that the caller can speak to anyone with another VoIP connection or a regular (or analog) phone line.

DSP is a technology that delivers acoustic protection and optimal sound quality through noise reduction, echo cancellation, and other algorithms to improve both transmit and receive quality.

DECT is a wireless communications technology that optimizes audio quality, lowers interference with other wireless devices, and is digitally encrypted for heightened call security.

Solutions
 
UC solutions continue to represent our primary focus area. Our portfolio of solutions, which combines hardware with highly innovative sensor technology and software functionality, provides the ability to reach people using the mode of communication that is most effective, on the device that is most convenient, and with control over when and how they can be reached. For example, the advanced sensor technology in our UC solutions can detect a user's presence, including proximity to the user's PC and whether the headset is being worn, and can share this information with others to make them aware of the user's presence and availability. Using this same technology, our solutions can automatically pause audio applications during an incoming call, change the default audio selection to the user's headset, and then answer the call; all of this is achieved without manual intervention. Finally, our solutions allow users to transition calls seamlessly between PCs, smartphones, tablets, and desk phones, without interruption in the conversation or loss in audio quality. We believe we are early in the UC solutions market adoption cycle and that UC systems will become more commonly adopted by enterprises to reduce costs and improve collaboration. We believe our solutions will be an important part of the UC environment through the offering of contextual intelligence.

Our products enhance communications by providing the following benefits:

Sensor technology that allows calls to be answered automatically when the user attaches the headset, switches the audio from the headset to the mobile phonedevice when the user removes the headset and, with some softphone applications, updates the user's presence

Smarter Working capability through seamless communications and high quality audio across a mobile device, desk phone, and PC, thereby allowing users to communicate more flexibly from a wide array of physical locations and be more productive when away from a traditional office environment
 
A convenient means for connecting between various applications and voice networks, whether between land lines and mobile phones,devices, or between PC-based communications and other networks

Better sound quality that provides clearer conversations on both ends of a call through a variety of features and technologies, including noise-canceling microphones, DSP, and more

Wireless freedom, allowing people to take and make calls as they move freely without cords or cables around their office or home, or easily from public to private space when privacy is required

Multi-tasking benefits that allow people to use computers and mobile devices, including smartphones or other devices, while talking hands-free

UC integration of telephony, mobile technologies, cloud-based communications, and PC applications, and by providing greater privacy than traditional speakerphones

Generating analytics related to headset usage, communications quality and other similar data our customers desire

Compliance with hands-free legislation and enhanced roadway safety by allowing users to have both hands free to drive while talking on a mobile phone

Voice command and control that allow people to take advantage of voice dialing and/or other voice-based features to make communications and the human/electronic interface more natural and convenient

Product Categories

Our products are designed to meet the needs of offices (ranging from enterprise to home offices), contact centers, mobile devices (such as mobile phones, smartphones, and smartphones)tablets), computer and gaming, residential, and other specialty applications.  These applications are increasingly overlapping as work styles and lifestyles change, and people use devices for multiple functions such as communication, music, and video entertainment.  We serve these markets through our product categories listed below.
 
Enterprise
 
The Enterprise market comprises our largest revenue stream and we believe it also represents our largest revenue and profit growth opportunity. We offer a broad range of communications headsets, including high-end, ergonomically designed headsets, audio processors, and telephone systems.  Our end-users consist of enterprise employees and small office, home office, and remote workers.  Growth in this category comes from the following three main factors:

Increasing deployment of UC solutions
Robust job market
Growing awareness of the benefits of using headsets, including the benefits of wireless solutions

The contact center category is the most mature in which we participate, and we expect this category to grow slowly over the long-term.  We expect that contactContact centers will alsohave begun to adopt UC to help improve productivity and reduce costs.  We expect this trend to continue. We develop audio endpoints tailored specifically to UC, and as UC adoption continues to increase, we expect to continue to lead in new product performance by creating solutions that combine hardware and software for an improved customer experience.

Consumer
 
We believe the mobile headset category will continue to grow as individuals use the technology for both communications and entertainment. The use of headsets designed for mobile phonesdevices represents a high volume opportunity and is our second largest revenue stream.  The use of mono headsets typically used with mobile phonesdevices has slowedexperienced a sharp decline over the past year, while the use of stereo Bluetooth technology has increased as individuals want to remain wireless without compromising on stereo sound quality. Our mono and stereo Bluetooth mobile headsets merge technological innovations with style, because we believe that style has become as important as functionality in shaping consumers' purchasing decisions in the wearable technology space.  While growth in the mono mobile headset market has slowed and continues to mature, we believe future growth will be driven primarily by demand for stereo Bluetooth technology.
 
Gaming and computer audio headsets, whether used for interactive on-line or console gaming, or switching between music and phone calls for multi-functional devices, represent an emerging opportunity for us. As devices providing these users' needs converge, our headsets need to be compatible with PCs, mobile phones, tablets, gaming consoles, and various combinations of these.  We believe our product development roadmaps address the convergence brought about by these needs and we are currently investing in this area to enable future growth.
 
Under our Clarity brand, we sell specialty products such as speakerphones, amplified captioned phones, amplified corded phones, personal listeners, and alarm clocks, all designed to address the unique needs of various consumer groups, one of which is the increasing number of people worldwide suffering from hearing loss.  We offer a comprehensive range of communications products that serve customers with mild, moderate, and severe hearing loss, as well as the deaf community.

FOREIGN OPERATIONS
 
In fiscal years 20152016, 20142015, and 20132014, net revenues outside the U.S. accounted for approximately 44%, 42%44%, and 43%42%, respectively, of our total net revenues.  Revenues derived from foreign sales are generally subject to additional risks, such as fluctuations in exchange rates, increased tariffs, the imposition of other trade restrictions or barriers, the impact of adverse global economic conditions, and potential currency restrictions.  In fiscal year 20152016, international revenues were reduced by approximately $4.7$27 million, net of the effects of hedging, due to unfavorable foreign exchange fluctuations in the other foreign currencies in which we sell.

We continue to engage in hedging activities to limit our transaction and economic exposures, and to mitigate our exchange rate risks.  We manage our economic exposure by hedging a portion of our anticipated Euro ("EUR") and British Pound Sterling ("GBP") denominated sales and our Mexican Peso ("MXN") denominated expenditures, which together constitute the most significant portion of our currency exposure.  In addition, we manage our balance sheet exposure by hedging EUR, GBP, and Australian Dollar ("AUD"), and Canadian Dollar ("CAD") denominated cash, accounts receivable, and accounts payable balances. Excess foreign currencies not required for local operations are converted into U.S. Dollars ("USD"). While our existing hedges cover a certain amount of exposure for fiscal year 2016,2017, long-term strengthening of the USD relative to the currencies of other countries in which we sell may have a material adverse impact on our financial results. In addition, while our existing hedges cover a certain amount of exposure for our fiscal year 2016, our results may be adversely impacted by future changes in foreign currency exchange rates relative to original hedging contracts generally secured up12 to 1224 months prior. See further discussion on our business risks associated with foreign operations under the risk titled, "We are exposed to fluctuations in foreign currency exchange rates, which may adversely affect our revenues, gross profit, and profitability" within Item 1A Risk Factors in this Form 10-K.

Further information regarding our foreign operations, as required by Item 101(d) of Regulation S-K, can be found in Note 1718, Geographic Information, of our Notes to Consolidated Financial Statements in this Form 10-K.

COMPETITION
 
The market for our products is very competitive and some of our competitors have greater financial resources than us,we do, as well as more substantial production, marketing, engineering and other capabilities to develop, manufacture, market, and sell their products.
 
One of our primary competitors is GN Netcom, a subsidiary of GN Store Nord A/S., a Danish telecommunications conglomerate that competes with us in the office, contact center, and mobile categories and, on a limited scale, in the gaming and computer audio categories.  In addition, Motorola, Samsung, LG, and BoseLG are significant competitors in the consumer mono Bluetooth headset category. Sennheiser Communications, Logitech, VXI, and regional companies are competitors in the computer, office, and contact center categories, while Beats, Skullcandy, and LG are competitors in the stereo Bluetooth Stereo headset category.  In addition, Turtle Beach, Skullcandy, and Razer are competitors in the gaming category.

We believe the principal factors to be successful and competitive in each of the markets we serve are as follows:

Our understandingUnderstanding of emerging trends and new communication technologies, such as UC, and our ability to react quickly to the opportunities they provide
Alliances and integration/compatibility with major UC vendors
Our abilityAbility to design, manufacture, and sell products that deliver on performance, style, comfort, features, sound quality, simplicity, price, and reliability
Maintenance of our brandBrand name recognition and reputation
Superior global customer service, support, and warranty terms
Effective and efficient global distribution channels that allow us to market and sell our solutions
Increasing globalGlobal reach

We believe that our products and strategy enable us to compete based on these factors.

RESEARCH AND DEVELOPMENT
 
We believe the future success of our business depends upon our ability to enhance our existing products, develop compelling new and cost-effective products, have our products qualified by our technology partners and customers, successfully introduce these products to existing and new markets on a timely basis, and to commence and sustain volume production to meet customer demands.

During fiscal year 2015, we developed and introduced innovative products that enabled us to better address changing customer demands and emerging trends.  Our goal is to bring the right products to customers at the right time and have best-in-class development processes.
In fiscal year 2016, we will continue to focus our core research and development efforts on UC, which will require incremental investments in firmware and software engineering to enhance the broad compatibility of our products with the enterprise systems into which they will be deployed and to develop value-added software applications for business users.  The products we are developing require significant technological knowledge, speed to market, and might be protected by intellectual property rights. Separately or together, this technological knowledge and our intellectual property gives us a competitive advantage. We are continually striving to improve the efficiency of our development processes through, among other things, strategic architecting, common platforms, and increased use of software and test tools.

The success of our new product introductions is dependent on a number of factors, including appropriate new product selection, timely completion and introduction, cost-effective manufacturing, quality, acceptance of new technologies, and general market acceptance.  See further discussion regarding our business risks associated with our manufacturers under the risk titled, "Our business will be materially adversely affected if we are unable to develop, manufacture, and market new products in response to changing customer requirements and new technologies" within Item 1A Risk Factors in this Form 10-K.

During fiscal years 2016, 2015,, 2014, and 2013,2014, we incurred approximately $90.4 million, $91.6 million, $84.8and $84.8 million,, and $80.4 million, respectively, in research, development, and engineering expenses.  Historically, we have conducted most of our research, development, and engineering with an in-house staff and the limited use of contractors.  Key locations for our research, development, and engineering staff are in the U.S., Mexico, China, the Netherlands, and the United Kingdom. 

During fiscal year 2016, we developed and introduced innovative products that enabled us to better address changing customer demands and emerging trends.  Our goal is to bring the right products to customers at the right time and have best-in-class development processes.
In fiscal year 2017, we will continue to focus our core research and development efforts on UC, which will require incremental investments in firmware and software engineering to enhance the broad compatibility of our products with the enterprise systems into which they will be deployed and to develop value-added software applications for business users.  In addition, in fiscal year 2017 we are launching new peripheral "as-a-service" offerings which we anticipate will complement our existing suite of product offerings as we move toward a hybrid business model of hardware, software, and services.

The products we are developing require significant technological knowledge and speed to market. Separately or together, this technological knowledge and our intellectual property gives us a competitive advantage. We continually strive to improve the efficiency of our development processes through, among other things, strategic architecting, common platforms, and increased use of software and test tools.

SALES AND DISTRIBUTION
 
We maintain a worldwide sales force to provide ongoing customer support and service globally.  To support our customers' needs, we have a well-established, multi-level distribution network in North America, Europe, and in some parts of the Asia Pacific region where use of our products is widespread. Our distribution channels in other regions are less mature, and while we primarily serve the Enterprise market in those regions, we are expanding into the Consumer market in those locations.

Our global commercial distributors includesales channel includes technology and electronics distributors, and national and regional resellers.  The resellers typically offer a wide variety of products from multiple vendors to both other resellers and end users.  Our commercial distribution channel generally maintains an inventory of our products.  Our distribution of specialty products includes distributors, retail, government programs, and health care professionals.
 

5


Our retail channel consists of both traditional and online consumer electronics retailers, consumer product retailers, office supply distributors, wireless carriers, catalog and mail order companies, and mass merchants.  Our headsets are sold through retailers to corporate customers, small businesses, and to individuals who use them for a variety of personal and professional purposes.  Revenues from this channel are seasonal, with our third fiscal quarter typically being the strongest quarter due to holiday seasonality. 

We have a diverse group of customers located throughout the world.  Our principal channel partners are distributors, retailers, and carriers.  Our commercial distributors and retailers represent our first and second largest sales channels in terms of net revenues, respectively.  No customer accounted for more than 10% of our consolidated net revenues in fiscal years 2016, 2015, 2014, or 2013.2014.

Our distributors, resellers, system integrators, e-commerce partners, telephony and computer equipment providers resell our commercial headsets and end point products. Wireless carriers, retailers, and e-commerce partners also sell our consumer headsets as Plantronics-branded products and in some cases, in their private label packaging. Carriers purchase headset products from us for use by their own agents and in some cases, also offer headsets to their customers.

We also make direct sales as a General Services Administration (“GSA”) contractor to certain government agencies in the U.S. These sales did not comprise a significant portion of our net revenues in fiscal years 2016, 2015, 2014, or 2013.

2014. In addition, certain distributors are authorized resellers under a GSA schedule price list and sell our products to government customers pursuant to that agreement.  

We have also established strong UC alliances with leading providers of UC software solutions, and these alliances enhance the sales and distribution of our products to large enterprises deploying UC solutions. In some cases, these partners also resell our solutions to customers as part of a broader communications solution.

Our products may also be purchased directly from our website at www.plantronics.com.

We continue to evaluate our logistics processes and implement new strategies to further reduce our transportation costs and improve lead-times to customers. Currently, we have distribution centers in the following locations:

Tijuana, Mexico, which provides logistics services for products destined for customers in the U.S., Canada, Asia Pacific, Middle East, and Latin America regions
Prague, Czech Republic, which provides logistics services for products shipped to customers in our Europe and Africa regions
Suzhou, China, which provides logistics services for products shipped to customers in Mainland China
Melbourne, Australia, which provides logistics services for products shipped to the retail channel in Australia and New Zealand
Sao Paulo, Brazil, which provides logistics services for products shipped to customers in Brazil
Tokyo, Japan, which provides logistics services for products shipped to customers in Japan

With respect to the above locations, we use third party warehouses in the Czech Republic, Australia, Brazil, and Japan. We operate all other warehouse facilities.facilities in Mexico and China.

BACKLOG
 
Our backlog of unfilled orders was $24.3$23.4 million and $26.6$24.3 million at March 31, 20152016 and 2014,2015, respectively.  We include all purchase orders scheduled for future delivery in backlog.  We have a “book and ship” business model whereby we fulfill the majority of orders within 48 hours of receipt of the order. As a result, our net revenues in any fiscal year depend primarily on orders booked and shipped in that year. In addition, our backlog is occasionally subject to cancellation or rescheduling by the customer on short notice with little or no penalty.  Therefore, there is a lack of meaningful correlation between backlog at the end of a fiscal year and the following fiscal year's net revenues. Similarly, there is a lack of meaningful correlation between year-over-year changes in backlog as compared with year-over-year changes in net revenues. As a result, we do not believe that backlog information is material to an understanding of our overall business.

MANUFACTURING AND SOURCES OF MATERIALS
 
Our manufacturing operations consist primarily of assembly and testing, both of which are performed in our manufacturing facility in Tijuana, Mexico.  We outsource the manufacturing of our Bluetooth products to third party manufacturers in China. We also outsource the manufacturing of a limited number of our other products to third parties, typically in China and other countries in Asia.  For a further discussion of the business risks associated with our manufacturers see the risk titled, “We have significant foreign manufacturing operations and rely on third party manufacturers located outside the U.S., and a significant amount of our revenues are generated internationally, which subjects our business to risks of international operations” within Item 1A Risk Factors in this Annual Report on Form 10-K.


We purchase the components for our products primarily from suppliers in Asia, Mexico, the U.S., and Europe, including proprietary semi-custom integrated circuits, amplifier boards, and other electrical components.  The majority of the components and sub-assemblies used in our manufacturing operations are obtained, or are reasonably available, from dual-source suppliers, although we do have a number of sole-source suppliers.

We procure materials to meet forecasted customer requirements.  Special products and certain large orders are quoted for delivery after receipt of orders at specific lead times.  We maintain minimum levels of finished goods based on estimated market demand, in addition to inventories of raw materials, work in process, sub-assemblies, and components.  In addition, a substantial portion of the raw materials, components, and sub-assemblies used in our products are provided by our suppliers on a consignment basis.  Refer to “Off Balance Sheet Arrangements”, within Item 7 Management's Discussion and Analysis, in this Annual Report on Form 10-K for additional details regarding consigned inventories. We write-down inventory items determined to be either excess or obsolete to their net realizable value.

ENVIRONMENTAL MATTERS
 

We are subject to various federal, state, local, and foreign environmental laws and regulations, including those governing the use, discharge, and disposal of hazardous substances in the ordinary course of our manufacturing process.  We believe that our current manufacturing and other operations comply in all material respects with applicable environmental laws and regulations. We are required to comply and we believe are currently in compliance with the European Union (“EU”) and other Directives on the Restrictions of the use of Certain Hazardous Substances in Electrical and Electronic Equipment (“RoHS”) and on Waste Electrical and Electronic Equipment (“WEEE”) requirements.  Additionally, we believe we are compliant with the RoHS initiatives in China and Korea; however, it is possible that future environmental legislation may be enacted or current environmental legislation may be interpreted to create an environmental liability with respect to our facilities, operations, or products. See further discussion of our business risks associated with environmental legislation under the risk titled, "We are subject to environmental laws and regulations that expose us to a number of risks and could result in significant liabilities and costs" within Item 1A Risk Factors of this Form 10-K.

INTELLECTUAL PROPERTY
 
We maintain a program of seeking patent protection for our technologies when we believe it is commercially appropriate.  As of March 31, 2015,2016, we had approximately 700775 worldwide patents in force, expiring between calendar years 20152016 and 2039.2040.

We intend to continue seeking patents on our inventions when commercially appropriate.

ITEM 1A.  RISK FACTORS
 
You should carefully consider the following risk factors in connection with any investment in our stock.  Our stock price will reflect the performance of our business relative to, among other things, our competition, expectations of securities analysts or investors, and general economic market and industry conditions.  Our business, financial condition, and results of operations could be materially adversely affected if any of the following risks occur.  Accordingly, the trading price of our stock could decline, and investors could lose all or part of their investment.

9


    
Adverse or uncertain economic conditions may materially adversely affect us.
Our operations and financial performance are dependent on the global economy. Uncertainty regarding future economic conditions makes it challenging to forecast operating results, make business decisions, and identify risks that may affect our business, sources and uses of cash, financial condition, and results of operations. Economic concerns, such as uncertain or inconsistent global or regional economic growth, stagnation or contraction, including the pace of economic growth in the United States in comparison to other geographic and economic regions, pressure on economic growth in Europe, uncertain growth prospects in the Asia Pacific region, as well as anxiety regarding geopolitical conflicts and their short and long-term economic impact, increase the uncertainty and unpredictability for our business as consumers, businesses and businessesgovernment agencies periodically and often unpredictably postpone or forego spending. A global economic downturn or continued erratic or declining business or governmental spending or hiring may reduce sales of our products, increase sales cycles, slow adoption of new technologies, increase price competition, and cause customers and suppliers to default on their financial obligations.
Replacement cycles of our Enterprise products are adversely impacted by lower voluntary employee turnover as new headset demand is typically created when employees feel confident enough to change employers or transition to new positions. While domestic voluntary turnover has improved in recent quarters,fiscal periods it remains below historical norms and certain market sectors are actually contracting. Moreover, slow and inconsistent international business hiring has perpetuated employee reluctance to change jobs, limitslimiting opportunities for unemployed workers to reenter the workforce and, consequently, impedes salesimpeding headset sales.

Additionally, although the nature and extent of our headsets.
Austerityausterity measures previously implemented by governments in various countries, including the U.S. and Europe, have curtailed, and may furtherare less severe in recent fiscal periods, those that remain reduce, demand for our products by affected governmentalgovernment agencies and by our customers who derive all or a portion of their revenues from these agencies. Similarly, to the extent uncertainty regarding public debt limits or budget negotiations,government budgets, particularly in the U.S and Europe, hinder spending by retail consumers, businesses or governmentalgovernment agencies, sales of our products may not grow as much as expected or may decrease or be delayed. We cannot predict the impact that governmental spending reductions or budget or debt negotiations will have on us or our customers or whether and to what extent our business and results of operations may be adversely harmed.
Additionally, our customers and suppliers suffer from their own financial and economic challenges. If global or regional economic conditions deteriorate, whether in general or particular market segments, one or more customers or suppliers may demand pricing accommodations, delay payments or shipments or become insolvent. It is impossible to reliably determine if and to what extent customers and suppliers may suffer, whether we will be required to adjust our prices or the amount we pay for materials and components or face collection issues with customers or if customer or supplier bankruptcies will occur.
We are exposed to differences and frequent fluctuations in foreign currency exchange rates, which may adversely affect our revenues, gross profit, and profitability.
Fluctuations in foreign currency exchange rates impact our revenues and profitability because we report our financial statements in USD, whereas a significant portion of our sales are transacted in other currencies, particularly the Euro and the British Pound Sterling ("GBP"). Furthermore, fluctuations in foreign currency rates impact our global pricing strategy, resultingwhich may result in our lowering or raising selling prices in one or more currencies in order to avoid disparity with USD prices and to respond to currency-driven competitive pricing actions. For example, the strengthening of the USD against numerous worldwide currencies that accelerated in the final months of the third quarter ofduring fiscal year 2015 and the continued strength of the USD throughout the fourth fiscal quarter hasyear 2016 negatively impacted our sales, pricing, margins, market share and operations overall. Should the dollar remain strong against foreign currencies, principally the Euro and the GBP, we may be compelled to raise prices for our customers in the affected regions. Price increases may be unacceptable to our customers who could seek to replace our products with lesserlower priced alternatives in which case our sales and market share may be adversely impacted. Otherwise, if we reduce prices to stay competitive in the affected regions our profitability may be harmed. We experienced $5.4 million in net foreign currency losses inIn fiscal year 2015.2016, international revenues were reduced by approximately $27 million, net of the effects of hedging, due to unfavorable foreign exchange fluctuations in the other foreign currencies in which we sell.
Large or frequent fluctuations in foreign currency rates, coupled with the ease of identifying global price differences for our products via the Internet, increases pricing pressure as well as the likelihood of additional unauthorized third party “grey market” salesresellers in varying countries takingwho take advantage of price disparities, thereby undermining our premium brand image, established sales channels, and operations.support and operations infrastructure. We also have significant manufacturing operations in Mexico and fluctuations in the Mexican Peso exchange rate can impact our gross profit and profitability. Additionally, the majority of our suppliers are located internationally, principally in Asia. Accordingly, volatileVolatile or sustained increases or decreases in exchange rates of Asian currencies may result in increased costs or reductions in the number of suppliers qualified to meet our standards.
Although we hedge currency exchange rates exposures we deem material, changes in exchange rates may nonetheless still have a negative impact on our financial results. Among the factors that may affect currency values are trade balances, the level of short-term interest rates, differences in relative values of similar assets in different currencies, long-term opportunities for investment and capital appreciation, decisions and actions of central banks and political developments.

10


We hedge a portion of our Euro and GBP forecasted revenue exposures for the future, typically over 12-month periods. In addition, we hedge a portion of our Mexican Peso forecasted cost of revenues and we havemaintain foreign currency forward contracts denominated in Euros, GBP, and Australian Dollars that hedge against a portion of our foreign-currency denominated assets and liabilities. Our foreign currency hedging contracts reduce, but do not eliminate, the impact of currency exchange rate movements, particularly if the fluctuations are significant or sustained, and we do not execute hedging contracts in all currencies in which we conduct business. There is no assurance that our hedging strategies will be effective. Additionally, even if our hedging techniques are successful in the periods during which the rates are hedged, our future revenues, gross profit, and profitability may be negatively affected both at current rates and by adverse fluctuations in currencies against the USD. For instance, because our hedging instruments cover a period of up to 24 months, we anticipate that the hedging conducted in fiscal year 2016 will deliver little benefit to offset the stronger U.S. Dollar against major currencies in fiscal year 2017. See Item 7A for further quantitative information regarding potential foreign currency fluctuations.

Our operating results are difficult to predict, and fluctuations may cause volatility in the trading price of our common stock.
Given the nature of the markets in which we compete, our revenues and profitability vary from quarter to quarter and are difficult to predict for many reasons, including the following:
variations in the volume and timing of orders received during each quarter;
the timing of customers' sales promotions and campaigns;
the timing of large customer deployments of UC infrastructure;
the timing of new product introductions by us and our competitors and phase outobsolescence or discontinuance of existing products;
competition, including pricing pressure, promotions and campaigns by us, our competitors or our customers;
failure to timely introduce new products within projected costs;
changes in technology and desired product features, including whether those changes occur in the manneranticipated manners and timeframe we anticipate;timeframes;
general economic conditions in the U.S. and in our international markets, including foreign currency fluctuations;
seasonality;
customer cancellations and rescheduling;
fluctuations in costs for components;raw materials and components costs;
shifts in product, geographic or channel mix; and
investments in and the costs associated with new product development and strategic initiatives.

Fluctuations in our operating results, including the failure to meet our expectations or the expectations of financial analysts, may cause volatility, including material decreases, in the trading price of our common stock.
The success of our business depends heavily on our ability to effectively market our UC products, and our business could be materially adversely affected if markets do not develop as we expectexpected or we are unable to compete successfully.
Our Enterprise products represent our largest source of revenue, and we regard the market for headsets designed for UC as our greatest long-term opportunity in the Enterprise market. We believe the implementation of UC technologies by large enterprises will be a significant long-term driver of UC headset adoption, and, as a result, a key long-term driver of our revenue and profit growth. Accordingly, we continue to invest in the development of new products and enhance existing products to be more appealing in functionality and design for the UC office market; however, there is no guarantee significant UC growth will occur, when it might occur, or that we will successfully take advantage of any growth thatit if it does occur.
Our ability to realize and achieve positive financial results from UC adoption could be adversely affected by a number of factors, including the following:
As UC becomes more widely adopted, competitors may offer solutions that will effectively commoditize our headsets, increases, which, in turn, may assert pressure on us to reduce the prices of one or more of our headset products.
The market success of major platform providers and strategic partners such as Microsoft Corporation, Cisco Systems, Inc., Avaya, Inc., Alcatel-Lucent, and Huawei, and our influence over such providers with respect to the functionality of their platforms and product offerings, their rate of deployment, and their willingness to integrate their platforms and product offerings with our solutions, is limited. For example, Microsoft’s Lync solution has become a large part of the UC marketplace and the decision by Microsoft to transition from Lync to Skype for Business isin early fiscal year 2016 proved to be a more significant market transition in the marketthan anticipated and may causecaused end customers to modify or pause their deployment schemes or schedules while assessingthey assessed the implications of Microsoft’s decision.
Failure to timely introduce solutions that are cost effective, feature-rich, stable, and attractive to our customers within forecasted development budgets.
Failure to successfully implement and execute new and different processes involving the design, development, and manufacturing of complex electronic systems composed of hardware, firmware, and software that works seamlessly and continuously in a wide variety of environments and with multiple devices.


11


Failure of UC solutions generally, or our solutions in particular, to be adopted with the breadth and speed that we currently anticipate. For example, concerns about data privacy and the security of information and data stored over the Internet and wireless security in general, each of which is further enabled by UC solutions, including our products, have caused entities in various markets to reassess thedata protection compliance and security safeguards of UC devices.
Failure of our sales model and expertise to support complex integration of hardware and software with UC infrastructure consistent with changing customer purchasing expectations.  
If new or evolving sales models such as our Software-as-a-Service, Device-as-a-Service offering in which we provide headsets to UC end customersor Soundscaping offerings provided on a subscription basis through channel partners are successful, they may have a long-term positive effect on our operations; however differences in revenue-recognition treatment may cause short-term revenue declines or increase expenditures for operational, administrative and technical support that may adversely impact our operations or negatively reflect on our overall growth.

Increased competition for market share, particularly given that some competitors have superior technical and economic resources enabling them to take greater advantage of UC market opportunities.
Sales cycles for more complex UC deployments are longer as compared to our traditional Enterprise products.
Our inability to timely and cost-effectively adapt to changes and future requirements of UC may impact our profitability in this market and our overall margins.
Failure to expand our technical support capabilities to support the complex and proprietary platforms in which our UC products are and will be integrated as well as increases in our support expenditures over time.

If our investments in, and strategic focus on, UC doesdo not generate incremental revenue, our business, financial condition, and results of operations could be materially adversely affected.
If we fail to accurately forecast demand we may under or overestimate production requirements resulting in lost business or write offs of excess inventory which may materially harm our business, reputation and results of operations.
Our industry is characterized by rapid technological changes, evolving industry standards, frequent new product introductions, short-term customer commitments, and changes in demand. Production levels are forecasted based on anticipated and historic product demand and we often place orders with suppliers for materials and components as well as finished products with our suppliers 13 weeks or more in advance of projected orders from our customers.customer orders. Actual demand depends on many factors and may vary significantly from our forecasts. We will lose opportunities to increase revenues and profits and may incur increased costs and penalties, including expedited shipping fees and late delivery penalties, if we underestimate customer demand.
Conversely, overestimating demand could result in higher inventories of raw materials, components, and sub-assemblies ("materials and components") and finished products, which may later require us to write off all or a material portion of our inventories. We routinely review inventory for usage potential, including fulfillment of customer warranty obligations and spare part requirements, and we write down to the lower of cost or market value the excess and obsolete inventory, which may adversely affect our results of operations.
For instance, periodically, we or our competitors announce new products, capabilities, or technologies that replace or shorten the life cycles of legacy products or cause customers to defer or stop purchasing legacy products until new products become available. Additionally, new product announcements may incite customers to increase purchases of successful legacy products as part of a last-time buy strategy, thereby increasing sales in the short-term while decreasing future sales byand delaying new product adoption. These risks increase the difficulty of accurately forecasting demand for discontinued and new products. Accordingly, during any transition to new products, we may experience inventory obsolescence and loss of revenue and associated gross profit.
If any of the above occur, our business, financial condition and results of operations could be materially harmed.
If our suppliers and sub-suppliers cannot timely deliver sufficient quantities of quality materials and components and finished products, our ability to fulfill customer demand may be adversely impacted and our growth, business, reputation and financial condition may be materially adversely effected.
Our growth and ability to meet customer demand depends in part on our ability to timely obtain sufficient quantities of materials and components as well as finished products of acceptable quality at acceptable prices. We buy materials and components from a variety of suppliers and assemble them into finished products. In addition, certain of our products and key portions of our products lines are manufactured for us by third party original design and contract manufacturers ("ODMs") who obtain materials and sub-components from a long and often complex chain of sub-suppliers. The cost, quality, and availability of the services, materials and components and finished products these ODMs and third parties supply are essential to our success.

12


Our reliance on these ODMs and third parties therefore involves significant risks, including the following:

We rely on suppliers for critical aspects of our business. For instance, we obtain a majority of our Bluetooth products from GoerTek, Inc. Suppliers such as GoerTek may choose to discontinue supplying materials and components or finished products to us for a variety of reasons, which may (i) be difficult, time-consuming, or costly to replace, (ii) force us to redesign or end-of-life certain products, (iii) delay manufacturing or render us unable to meet customer demand, or (iv) require us to make large last-time buys in excess of our short-term needs, holding materials and components or finished products in inventory for extended periods of time. Consequently, ifIf one or more suppliers is unable or unwilling to meet our demand, delivery, or price requirements, our business and operating results could be materially adversely affected.
Although we preferendeavor to use standard materials and components in our products whenever feasible, the lack of viable alternative sources or the high development costs associated with existing and emerging wireless and other technologies may require us to work with a single source for silicon chips, chip-sets, or other materials and components in one or more products. Moreover, lead times are particularly long for silicon-based components incorporating radio frequency and digital signal processing technologies and such materials and components make up an increasingly larger portion of our product costs.  Additionally, many consumer product orders have shorter lead times than component lead times, makingwhich may make it increasingly necessary for us or our suppliers to carry more inventory in anticipation of orders, which may not materialize.

A substantial portion of the materials and components used in our products are provided by our suppliers on consignment. As such, we do not take title to the materials and components until they are consumed in the production process. Prior to consumption, title and risk of loss remains with the suppliers. Our supply agreements generally allow us to return parts in excess of maximum order quantities at the suppliers’ expense. Returns for other reasons are negotiated with suppliers on a case-by-case basis and to date have been immaterial. If we are required or choose to purchase all or a material portion of the consigned materials and components or if a material number of our suppliers refuse to accept orders on consignment, we could incur material unanticipated expenses, including write-downs for excess and obsolete inventory.inventory and result in inventory turn rate declines.
Rapid increases in production levels to meet product demand, whether or not forecasted, could result in shipment delays, higher costs for materials and components, increased expenditures for freight to expedite delivery of required materials, late delivery penalties, and higher overtime costs and other expenses, which could negatively impact our revenues, reduce profit margins, and harm relationships with affected customers. For instance, beginning in the first quarter of fiscal year 2015, sales of our BackBeat Fit have beenwere constrained by limited sub-component supply availability. If we are unablesimilar constraints were to occur in existing or future product lines, our ability to meet demand and our corresponding ability to sell affected products may be materially reduced. Moreover, our failure to timely deliver desirable products like the BackBeat Fit when requested,to meet demand may harm relationships with our customers may be harmed.customers. Further, if production is increased rapidly, manufacturing yields may decrease, which may also reduce our revenues or margins.

Any of the foregoing could materially and adversely affect our business, financial condition, and results of operations.
Prices of certain raw materials, components, semiconductors, and sub-assemblies may rise depending upon global market conditions which may adversely affect our margins.
We have experienced and expect to continue to experience volatility in prices from our suppliers, particularly in light of the price fluctuations offor oil, gold, copper, and other materials and components in the U.S. and around the world, which could negatively affect our profitability or market share. If we are unable to pass cost increases on to our customers or achieve operating efficiencies that offset any increases, our business, financial condition, and results of operations may be materially and adversely affected.
We have strong competitors and expect to face additional competition in the future. If we are unable to compete effectively, our results of operations may be adversely affected.
All of the markets in which we sell our products are intensely competitive and market leadership may change as a result of new product introductions and pricing. We face pressure on our selling prices, sales terms and conditions, and in connection with product performance and functionality. Also, aggressive industry pricing practices may result in decreasing margins.
One of our primary competitors is GN Netcom, a subsidiary of GN Store Nord A/S (“GN”), a Danish telecommunications conglomerate with whom we compete in the office, contact center,Enterprise and mobile categories. We also compete with consumer electronics companies that manufacture and sell mobile phones, tablets, or computer peripheral equipment. Many of our competitors are larger, offer broader product lines, may integrate their products with communications headset devices and adapters manufactured by them or others, offer products incompatible with our headsets, and have substantially greater financial, marketing, and other resources.
Competitors in audio devices vary by product line.  Our most competitive product line is headsets for cell phones where we compete with GN's Jabra brand, Motorola, Samsung, and LG, among many others.  Many of these competitors have substantially greater resources than us, and each has an established market position. For sales of our Enterprise products, including UC, our largest competitors areinclude GN, Sennheiser Communications, Logitech, and VXI. For our Consumer products, our primary competitors areinclude Sennheiser, Logitech, Beats, LG, Jaybird, Motorola, Samsung and Bose. In the gaming category of our Consumer products market, our primary competitors are Turtle Beach, Skullcandy, and Razer.

13


We face additional competition from companies, principally located in or originating from the Asia Pacific region, which offer very low cost headset products, including products modeled on, direct copies of, or counterfeits of our products. Furthermore, online marketplaces make it easier for disreputable and fraudulent sellers to introduce their copies or counterfeit products into the stream of commerce by commingling legitimate products with copies and counterfeits; thereby making it extremely difficult to track and remove copies and counterfeits. The introduction of low cost alternatives, copies and counterfeits has resulted in and will continue to cause market pricing pressure, customer dissatisfaction and harm to our reputation and brand name. If market prices are substantially reduced by new or existing participants in the headset categories, our business, financial condition, or results of operations could be materially and adversely affected.
If we do not distinguish our products, particularly our Consumer products, through distinctive, technologically advanced features and design, as well as continue to build and strengthen our brand recognition, our products may become commoditized and our business could be harmed.  In addition, failure to effectively market our products to customers could lead to lower and more volatile revenue and earnings, excess inventory, and the inability to recover associated development costs, any of which could also have a material adverse effect on our business, financial condition, results of operations, and cash flows.

The markets for our Consumer products are volatile and our ability to compete successfully in one or more of these categories is subject to many risks.
Competition inIn the markets for our Consumer products, which consist primarily of Bluetooth headsets, gaming, entertainment and computer audio headsets, is intense and presentswe face many significant manufacturing, marketing and operational risks and uncertainties. The risks include the following:
The global market for mono Bluetooth headsets is shrinking or flat,shrunk significantly in 2015, which iswas at least partially attributable to the integration of Bluetooth systems into automobiles. The market for stereo Bluetooth headsets continues to grow rapidly, although it remains dominated by lifestyle brands. Our market share has been and is significantly larger in the mono market than in the stereo market and it remains unclear whetherthus far we will be ablehave been unable to sufficiently increase share in the stereo market to continue growingoffset decreases in the overallmono Bluetooth market forand although we expect stereo Bluetooth headsets.product sales to increase, the future of this market remains unclear.
Reductions in the number of suppliers participating in the Bluetooth market has reduced our sourcing options and may in the future increase our costs at a time when our ability to offset higher costs with product price increases is limited.
Difficulties retaining or obtaining shelf space and maintaining a robust and compelling eCommerce presence for our Consumer products in our sales channel, particularly with large "brick and mortar" retailers and Internet "etailers" as the market for mono Bluetooth headsets contracts or remains flat.contracts.
Relying on a dwindling number of retail customers that have significant market share in the shrinking mono Bluetooth category increases our exposure to pricing pressure, unexpected changes in demand and may result in unanticipated fluctuations in our revenues and margins.
The varying pace and scale of economic activity in many regions of the world creates demand uncertainty and unpredictability for our Consumer products.
The need to rapidly and frequently adopt new technology to keep pace with changing market trends.  In particular, we anticipate a trend towards more integrated solutions that combine audio, video, and software functionality that we expect will shorten product lifecycles.
Our ability to maintain insight into, and quickly respond to, sudden changes in laws or regulations.

FailureCompetition in the consumer business market is intense and failure to compete successfully in the consumer businessthese markets may have an adverse effect on our business, results of operations, and financial condition.
We cannot guarantee we will continue to repurchase our common stock pursuant to stock repurchase programs or that we will declare future dividend payments at historic rates or at all. The repurchase of our common stock and the payment of dividends may require us to borrow against our Credit Agreement or incur indebtedness and may not achieve our objectives.
In March 2015, we announced a new corporate return of capital policy with the goal of increasing the return of cash to stockholders to approximately 60% of free cash flow, defined as total operating cash flow less capital expenditures. We intend to achieve this goal primarily through stock repurchases and quarterly dividends. In conjunction with the March 2015 announcement regarding our new return of capital policy, we increased our then-existing stock repurchase program from one million shares to four million shares and approved another stock repurchase program in January 2016 for an additional one million shares. Moreover, our Board of Directors has consistently declared quarterly dividends over the years.
Any determination to pay cash dividends at recent rates or at all, or authorization or continuance of any share repurchase programs is contingent on a variety of factors, including our financial condition, results of operations, business requirements, and our Board of Directors' continuing determination that such dividends or share repurchases are in the best interests of our stockholders and in compliance with all applicable laws and agreements. Accordingly, there is no assurance that we will continue to repurchase stock at recent historical levels or at all, or that our stock repurchase programs or dividend declarations will have a beneficial impact on our stock price.

We5.50% senior unsecured notes and entered into an Amended and Restated $100.0 million revolving line of credit facility. Issuance of the notes and any draws against the credit facility may also decideadversely affect our future financial condition and financial results.
As of March 31, 2016, we had $500 million in 5.50% senior unsecured notes outstanding and the ability to draw up to $100.0 million against a revolving line of credit agreement with Wells Fargo Bank, National Association, although at March 31, 2016, we had no amounts outstanding under the credit facility. Risks relating to our long-term indebtedness include:
Requiring us to dedicate a portion of our cash flow from operations to payments on our currently existing or future indebtedness, thereby reducing the availability of cash flow to fund working capital, capital expenditures, acquisitions, investments and other general corporate purposes;
Limiting our flexibility in planning for, or reacting to, changes in our business and the markets in which we operate including, without limitation, restricting our ability and the ability of our subsidiaries to incur indebtednessliens or enter into certain types of transactions such as sale and lease-back transactions; and
Limiting our ability to support our repurchases, dividendsborrow additional funds or to borrow funds at rates or on other activities. Weterms we find acceptable.

Periodically, we have previously drawn funds and have increased the frequency and amount of draws under our Credit Agreementexisting credit facilities in connection with our corporate return of capital policy and generally from time to time.for other purposes. Amounts drawn under the Credit Agreementour outstanding credit agreement are subject to interest charges. Moreover, the Credit Agreementcredit agreement contains affirmative and negative covenants with which we must comply.comply in addition to those covenants in our senior unsecured notes. These restrictions apply regardless of whether any loans under the credit agreement are outstanding and could adversely impact how we operate our business, our operating results, and dividend declarations, which, in turn, may negatively impact our stock price. During the fourth quarter of fiscal year 2016, we breached the funded debt to EBITDA ratio covenant of our credit agreement for which we subsequently obtained a waiver from Wells Fargo in the first quarter of fiscal year 2017. Although we have amended the credit agreement to reduce the risk of future violations of the covenant, we cannot be sure we will not breach this or any other covenant in the future or that Wells Fargo will not seek to enforce any or all remedies against us for any same or similar breach.
In addition, asif we borrow additional funds under the Credit Agreement,credit agreement, we may be required to increase the borrowing limit under the Credit Agreementcredit agreement or seek additional sources of borrowing. Given current credit and debt markets, there is no assurance that if we were to seek additional credit or debt, it would be available when needed or if it is available, the cost or terms and conditions would be acceptable.
Were any of the foregoing risks to occur, we may be unable to pay any indebtedness, including interest, when due, and may be required to curtail activities to comply with our obligations under the senior unsecured notes. Additionally, changes by any rating agency to our credit rating may negatively impact the value and liquidity of both our debt and equity securities, as well as the potential costs associated with a refinancing of our debt. The rating agencies measure us by our performance against certain financial metrics. If we do not meet these metrics there is a risk the rating agencies may downgrade our rating. Under certain circumstances, if our credit ratings are downgraded or other negative action is taken, our ability to obtain additional financing in the future could be diminished and could affect the terms of any such financing. If any of those things occur, our financial condition and results of operations may be adversely affected.
Our corporate tax rate may increase or we may incur additional income tax liabilities, which could adversely impact our cash flow, financial condition and results of operations.
We have significant operations in various tax jurisdictions throughout the world, and a substantial portion of our taxable income has historically been generated in jurisdictions outside of the U.S. Currently, some of our operations are taxed at rates substantially lower than U.S. tax rates. If our income in these lower tax jurisdictions were no longer to qualify for these lower tax rates, the applicable tax laws were rescinded or changed, or the mix of our earnings shifts from lower rate jurisdictions to higher rate jurisdictions, our operating results could be materially adversely affected. In addition, variousFurthermore, the repatriation of non-U.S. earnings for which we have not previously provided U.S. taxes could result in higher effective tax rates for us and subject us to significant additional U.S. income tax liabilities.
Various governmental tax authorities have recently increased their scrutiny of tax strategies employed by corporations and individuals. In addition, the Organization for Economic Cooperation and Development issued guidelines and proposals during fiscal year 2016 that may change how our tax obligations are determined in many of the countries in which we do business. If U.S. or other foreign tax authorities change applicable tax laws or successfully challenge the manner in which our profits are currently recognized, our overall taxes could increase, and our business, cash flow, financial condition, and results of operations could be materially adversely affected.

We are also subject to examination by the Internal Revenue Service ("IRS") and other tax authorities, including state revenue agencies and foreign governments. In July 2012, the IRS commenced an examination of our 2010 tax year. While we regularly assess the likelihood of favorable or unfavorable outcomes resulting from examinations by the IRS and other tax authorities to determine the adequacy of our provision for income taxes, there can be no assurance that the actual outcome resulting from these examinations will not materially adversely affect our financial condition and results of operations.

Our business will be materially adversely affected if we are unable to develop, manufacture, and market new products in response to changing customer requirements and new technologies.
The technology used in our products is evolving more rapidly now than in the past and we anticipate this trend will continue. Historically, new products primarily offered stylistic changes and quality improvements rather than significant new technologies. Our increasing reliance and focus on the UC market has resulted in a growing number of our products that integrate complex, state-of-the-art technology, increasing the risks associated with new product ramp-up, including product performance and defects in the early stages of production. For example, in the fourth quarter of fiscal year 2015, we announced the recall of a newly launched product, the Encore Pro, that failed to meet our quality standards. The recall negatively impacted revenues in the fourth quarter of fiscal year 2015 and the first quarter of fiscal year 2016.
Office phones have begun to incorporate Bluetooth functionality, which has opened the market to consumer Bluetooth headsets and reduced the demand for our traditional office telephony headsets and adapters, which has resultedresulting in lost revenue and lower margins. Additionally, with the advent of more and different types of mobile devices the need for traditional desk phones with a distinct headset is decreasing, and may limit the sale of both corded and cordless headsets in the future. Moreover, the increasing adoption of wireless headsets has also resulted in increased development costs associated with the introduction of new wireless standards and more frequent changes in those standards and capabilities as compared to wired technologies. If sales and margins on our traditional corded products decline and we are unable to successfully design, develop, and market alternatives at historically comparable margins, our revenue and profits may decrease.
In addition, innovative technologies such as UC have moved the platform for certain of our products from our customers' closed proprietary systems to open platforms such as the PC, smart phonessmartphones and tablets. In turn, these devices have become more open as a result of technologies such as cloud computing and trends toward more open source software code development. As a result, the risk that current and potential competitors could enter our markets and commoditize our products by offering similar products has increased.

The success of our products depends on several factors, including our ability to:

Anticipate technology and market trends
Develop innovative new products and enhancements on a timely basis
Distinguish our products from those of our competitors
Create industrial designs that appeal to our customers and end-users
Manufacture and deliver high-quality products that are simple to operate in sufficient volumes and acceptable margins
Price our products competitively
Hire and retain qualified personnel in the highly competitive field of software development
Provide timely, effective and accurate technical product support to our customers
Leverage new and existing channel partners effectively

If we are unable to develop, manufacture, market, and introduce enhanced or new products in a timely manner in response to changing market conditions or customer requirements, including changing fashion trends and styles, our business, financial condition, and results of operations will be materially adversely affected.
We have significant foreign manufacturing operations and rely on third party manufacturers located outside the U.S., and a significant amount of our revenues are generated internationally, which subjects our business to risks of international operations.
We own and operate a manufacturing facility in Tijuana, Mexico. We also have suppliers, contact manufacturers, and other vendors throughout Asia and generate a significant amount of our revenues from foreign customers.
Our international operations and sales expose us to various risks including, among others:
Fluctuations in foreign currency exchange rates
Cultural differences in the conduct of business
Greater difficulty in accounts receivable collection and longer collection periods
The impact of recessionary, volatile or adverse global economic conditions
Reduced protection for intellectual property rights protections in some countries
Changes in regulatory requirements
The implementation or expansion of trade restrictions, sanctions or other penalties against one or more countries, its citizens or industries

Tariffs, taxes and other trade barriers, particularly in developing nations such as Brazil, India, and others
Political conditions, health epidemics, civil unrest, or criminal activities within each countrycountries in which we operate
The management, operation, and expenses associated with an enterprise spread over various countries
The burden and administrative costs of complying with a wide variety of foreign laws and regulations
Currency restrictions
Compliance with anti-bribery laws, including the United States Foreign Corrupt Practices Act and the United Kingdom's Bribery Act

The above-listed and other inherent risks of international operations could materially and adversely affect regional economic activity and business operations in general, which in turn may harm our business, financial condition, and results of operations.
We sell our products through various distribution channels that can be volatile, and failure to establish and maintain successful relationships with our channel partners could materially adversely affect our business, financial condition, or results of operations. In addition, customer bankruptcies or financial difficulties may impact our business.
We sell substantially all of our products through distributors, retailers, OEMs, and telephony service providers. Effectively managing these relationships and avoiding channel conflicts is challenging. Our existing relationships with these parties are generally not exclusive and can be terminated by us or them without cause on short notice. These customers also sell or may sell products offered by our competitors. To the extent our competitors offer more favorable terms or more compelling products, theyour customers may not recommend, de-emphasize, or discontinue carrying our products. Moreover, our OEMs may elect to manufacture their own products that are similar to ours.those we offer. Additionally, it is becoming easier for small online sellers to enter the market unburdened with physical locations, employees and support personnel which can force our larger traditional brick and mortar resellers to reduce their selling prices and inprices. In turn, our traditional resellers may demand lower selling prices from us.us, reduce their sales support needed to maintain our premium brand image, discontinue carrying our products and other similar adverse actions. The inability to establish or maintain successful relationships with distributors, OEMs, retailers, and telephony service providers or to expand our distribution channels and sales models could materially adversely affect our business, financial condition, or results of operations.

16


As a result of the evolution of our consumer business, ourOur customer mix is changing, and certain retailers, OEMs, and wireless carriers are more significant.  In particular, we have several large customers whose order patterns are difficult to predict. Offers and promotions by these customers may result in significant fluctuations in their purchasing activities over time, which may increase the volatility of our revenues.  If we are unable to correctly anticipate the quantities and timing of their purchase requirements, our revenues may be adversely affected, or we may be left holding large volumes of inventory that cannot be sold to other customers.
Furthermore, many customers with whom we conduct business have substantial buying power or have strategic importance to our product marketing objectives. Many use their buying power or strategic importance to mandate onerous terms and conditions in our business arrangements with them including unfavorable payment terms, fees and penalties for early, late and inaccurate shipments, generous return rights, most favored pricing, and mandatory marketing and promotional fees. These terms are often non-negotiable and are frequently broad, ambiguous and inconsistent across customers making compliance complex and subject to interpretation. If our compliance with these or similar future provisions are incorrect or inadequate, we could be liable for breach of contract damages or our reputation with one or more key customers could be materially adversely harmed, either of which could have an adverse effect on our financial condition or results of operations.
Also, in order to provide us with greater insight into the characteristics and control overmotivations of our distribution channels as well as the needs of our end customers, to better incentivize our sales partners and promote our products to end customers, we implementedhave begun regional implementation of an authorization program in whichas well as a back end rebate program. Under the authorization program, distributors and resellers are asked to enter into agreements or supplement existing agreements in connection with the sale of all or a portion of our products. OurThe back end rebate program ties payment of post-sale discounts to distributor program compliance obligations. These programs are new and our partners may deem the programthem difficult, time-consuming or disruptive, or the terms of the programprograms or our agreements unacceptable.
Additionally, we have implemented an electronic minimum advertised pricing policy applicable to a number of new and future products as well as certain legacy products. The policy allows us to limit and reject orders from resellers who fail to promote and maintain the premium image of our brand and products by advertising online prices for covered products below prices we establish and periodically adjust. Enforcement of the policy may result in lost sales and harm our business relationships and reputation, potentially materially, with one or more customers or resellers.
If the number and quality of our distributors and resellers declines, our business, financial condition, and results of operations could be materially, adversely affected.

The increased use of software in our products or as standalone applications could impact the way we recognize revenue which, if material or done incorrectly, could adversely affect our financial results.
We are increasingly incorporating advanced software features and functionalities into our products, offering firmware and software fixes, updates, and upgrades electronically over the Internet and developing standalone software applications.Internet based software-as-a-service offerings that provide additional value that complements our headsets. As the nature and extent of software integration in our products increases or if sales of standalone software applications or services become material, the way we report revenue related to our products and services could be significantly affected. For example, we are increasingly required to evaluate whether our revenue transactions include multiple deliverables and, as such, whether the revenue generated by each transaction should be recognized upon delivery, over a period of time or apportioned and recognized based on a combination of the two in light of all the facts and circumstances related to each transaction. Moreover, the software and services revenue recognition rules are complex and dynamic.
If we fail to accurately apply these complex rules and policies, particularly to new and unique products or services offerings, we may incorrectly report revenues in one or more reporting periods. If this were to occur and the error was material, we may be required to restate our financial statements, which could materially and adversely impact our results for the affected periods, cause our stock price to decline, and result in securities class actions or other similar litigation.
Investment in new business strategies and acquisitions are disruptive and may present risks to our current and future business operations.

We have invested, and in the future will continue to invest, in new business strategies and acquisitions. Such endeavors and acquisitions will involve significant risks and uncertainties which may include:

Distraction of management from current operations;
Greater than expected liabilities and expenses;
Inadequate return on capital;
Insufficient sales and marketing expertise requiring costly and time-consuming development and training of internal sales and marketing personnel as well as new and existing distribution channels;
Prohibitive or ineffective intellectual property rights or protections;
Unknown market expectations regarding pricing, branding and operational and logistical levels of support;
Uncertain tax, legal and other regulatory compliance obligations and consequences;
New and complex data collection, maintenance, privacy and security requirements; and
Other unidentified issues not discovered in our investigations and evaluations.

We have announced and are exploring new service offerings including software-as-a-service, device-as-a-service and Soundscaping. Although, elements of each of these services are founded on intellectual property or one or more areas in which we believe we have expertise, they remain complex undertakings different in material respects from our historical hardware design, development and sales model. For example, although software-as-a-service has become a familiar business model generally, recurring revenue subscription services are new to us and involve unique development, accounting and support requirements. Moreover, device-as-a-service and Soundscaping are not nearly as well accepted or understood generally. Device-as-a-service in particular involves significant up-front costs, limited product recovery options and may require significant sales and marketing educational campaigns both internally and throughout our distribution channels. Furthermore, each of these services remain in the early stages of development and require significant additional time, effort and costs to develop before their likelihood of market success can be determined with any degree of certainty.

Additionally, in order to support or further our new services offerings, we may decide to make investments or acquisitions, including through joint ventures. Depending on the investments, we may have limited or no management or operational control in the companies in which we invest or the acquisition may prove difficult to integrate into our existing operations or otherwise unsuccessful. Further, we may issue shares of our common stock in these transactions, which could result in dilution to our stockholders.

If we fail to anticipate the time, effort and cost to develop and maintain new business strategies and acquisitions, we do not timely meet market expectations for commercial availability, our service and support proves unreliable, or we are unable to offer these services at acceptable profit margins, our existing and future business, financial condition, and results of operations could be materially, adversely affected.


Our intellectual property rights could be infringed on by others, and we may infringe on the intellectual property rights of others resulting in claims or lawsuits. Even if we prevail, claims and lawsuits are costly and time consuming to pursue or defend and may divert management's time from our business.
Our success depends in part on our ability to protect our copyrights, patents, trademarks, trade dress, trade secrets, and other intellectual property, including our rights to certain domain names. We rely primarily on a combination of nondisclosure agreements and other contractual provisions as well as patent, trademark, trade secret, and copyright laws to protect our proprietary rights. Effective trademark, patent, copyright, and trade secret protection and enforcement of our intellectual property rights may not be available in every country in which our products and media properties are distributed to customers. The process of seeking intellectual property protection can be lengthy, expensive, and uncertain. Patents may not be issued in response to our applications, and any patents that may be issued may be invalidated, circumvented, or challenged by others. If we are required to enforce our intellectual property or other proprietary rights through litigation, the costs and diversion of management's attention could be substantial. Furthermore, we may be countersued by an actual or alleged infringer if we attempt to enforce our intellectual property rights, which may materially increase our costs, divert management attention, and result in injunctive or financial damages being awarded against us. In addition, the existing patents, copyright registrations, trademarks, trade secrets and domain names may not provide us competitive advantages or be adequate to safeguard and maintain our proprietary rights. If it is not feasible or possible to obtain, enforce, or protect our intellectual property rights, our business, financial condition, and results of operations could be materially, adversely affected.

Patents, copyrights, trademarks, and trade secrets are owned by individuals or entities that may make claims or commence litigation based on allegations of infringement or other violations of intellectual property rights. These claims or allegations may relate to intellectual property that we develop or the intellectual propertythat is incorporated in the materials or components provided by one or more suppliers. As we have grown, the intellectual property rights claims against us and our suppliers have increased. There has also beenincreased along with a general trend of increasing intellectual property infringement claims against corporations that make and sell products.all corporations. Our products, technologies and the components and materials contained in our products may be subject to certain third-party claims and, regardless of the merits of the claim, intellectual property claims are often time-consuming and expensive to litigate, settle, or otherwise resolve. In addition, to the extent claims against us or our suppliers are successful, we may have to pay substantial monetary damages or discontinue the manufacture and distribution of products that are found to be in violation of another party's rights. We also may have to obtain, or renew on less favorable terms, licenses to manufacture and distribute our products or materials or components included in those products, which may significantly increase our operating expenses. In addition,Moreover, many of our agreements with our distributors and resellers require us to indemnify them for certain third-party intellectual property infringement claims. Discharging our indemnity obligations may involve time-consuming and expensive litigation and result in substantial settlements or damages awards, our products being enjoined, and the loss of a distribution channel or retail partner, any of which may have a material adverse impact on our operating results.
We must comply with various regulatory requirements, and changes in or new regulatory requirements may adversely impact our gross margins, reduce our ability to generate revenues if we are unable to comply, or decrease demand for our products if the actual or perceived quality of our products are negatively impacted.
Our products must meet requirements set by regulatory authorities in each jurisdiction in which we sell them. For example, certain of our Enterprise products must meet local phone system standards. Certain of our wireless products must work within existing permitted radio frequency ranges. Moreover, competition for limited radio frequency bandwidth as a result of an increasing use of wireless products increases the risk of interference or diminished product performance. In particular, the release of a third party wireless deviceFor instance, in the U.S. that operatesthe increase in the number of products operating in the unlicensed 903-928 megahertz radio frequency range using significantly higher power than our wireless products and those of many other users of the unlicensed frequency range may cause our wireless products to experience interference which, if material, may harm our reputation and adversely affect our sales.
As regulations and local laws change and competition increases, we may need to modify our products to address those changes. Regulatory restrictions and competition may increase the costs to design, manufacture, and sell our products, resulting in a decrease in our margins or a decrease in demand for our products if we attempt to pass along the costs. Compliance with regulatory restrictions and bandwidth limitations may impact the actual or perceived technical quality and capabilities of our products, reducing their marketability. In addition, if the products we supply to various jurisdictions fail to comply with the applicable local or regional regulations, if our customers or merchants providetransfer products into unauthorized jurisdictions or our products interfere with the proper operation of other devices, we or consumers purchasing our products may be responsible for the damages that our products cause; thereby causing us to alter the performance of our products, pay substantial monetary damages or penalties, cause harm to our reputation, or cause us to suffer other adverse consequences.
Moreover, new regulations may negatively adversely affect our ability to procure or manufacture our products. For instance, as part of the Dodd-Frank Wall Street Reform and Consumer Protection Act, the Securities and Exchange Commission ("SEC") adopted disclosure requirements regarding theour use of certain minerals, known as conflict minerals, which are minedin our products and the suppliers who provide those minerals, particularly from and around the Democratic Republic of Congo, and adjoining countries, as well as procedures regarding a manufacturer's efforts to identify and prevent the sourcing of such minerals and metals produced from those minerals. Additional reporting obligations are being considered by the European Union. The U.S. requirements and any additional European requirements could affect the sourcing and availability of metals used in the manufacture of a number of parts contained in our products. For example, these disclosure requirements may decrease the number of suppliers capable of supplying our needs for certain metals or we may be unable to conclusively verify the origins of all metals used in our products. We may suffer financial and reputational harm if customers require, and we are unable to deliver, certification that our products are conflict free. Regardless, we continue to incur costs associated with compliance, including time-consuming and costly efforts to determine the source of minerals used in our products.

We are exposedregularly subject to potential lawsuits alleging defects in our productsa wide variety of litigation including commercial and otheremployment litigation as well as claims related to alleged defects in the design and use of our products.

We are regularly subject to a wide variety of litigation including claims, lawsuits, and other similar proceedings involving our business practices and products including claims and disputes regarding product liability, labor and employment, and commercial matters. The number and significance of these claims and disputes have increased as our company has grown larger, our business has expanded in scope and geographic reach, and our products and services have increased in complexity.

For instance, the sales of our products expose us to the risk of product liability claims, including those alleging hearing loss claims. Although product-related claims are asserted against us periodically, to date none of the claims have materially affected our business, financial condition, or results of operations. Nevertheless, there is no guarantee that future claims will not materially negatively impact our business or result in substantial damages, or both.

loss. Additionally, our mobile headsets are used with mobile telephones and there has been public controversy over whether the radio frequency emissions from mobile phones are harmful to users of mobile phones. We are unaware of any conclusive proof of any health hazard from the use of mobile phones, butLikewise, research in this area continues and if it establishes a health hazard from the use of mobile phones or public controversy grows even in the absence of conclusive research findings, the likelihood of litigation against us may increase.  Likewise, should researchcould establish a link between radio frequency emissions and corded or wireless headsets or should we could become a party to litigation claiming such a link and public concern in this area grows, demand for our corded or wireless headsets could be reduced creating a material adverse effect on our financial results.
link. There is also continuing public controversy over the use of mobile phones by operators of motor vehicles. While we believe our products enhance driver safety by permitting a motor vehicle operator to generally keep both hands free to operate the vehicle, there is no certainty that this is the case,vehicles and we may be subject to allegations that use of a mobile phone and headset contributed to a motor vehicle accident.

In addition, we have been sued by employees regarding our employment practices and business partners regarding contractual rights and obligations. We have also been sued by a competitor, GN Netcom, Inc., regarding alleged violations of certain laws regulating competition and business practices which lawsuit is more specifically described in Part I, Item 3 under the caption "Legal Proceedings" and Part II, Item 8, Note 8 under the caption "Commitments and Contingencies" of this Annual Report on Form 10-K.

Frequently, the outcome and impact of any claims, lawsuits, and other similar proceedings cannot be predicted with certainty. Moreover, regardless of the outcome such proceedings can have an adverse impact on us because of significant legal costs, diversion of management resources, and other factors. Determining reserves for our pending litigation is a complex, fact-intensive process that is subject to judgment calls. It is possible that a resolution of one or more such proceedings could require us to make substantial payments to satisfy judgments, penalties or to settle claims or proceedings, any of which could harm our business. These proceedings could also result in reputational harm, sanctions, consent decrees, or orders preventing us from offering certain products, or services, or requiring a change in our business practices in costly ways. Any of these consequences could materially harm our business.

We maintain product liability insurance and general liability insurance in amounts we believe sufficient to cover reasonably anticipated claims, including some of those described above; however, the coverage provided under the policies could be inapplicable or insufficient to cover the full amount of any one or more claims. Therefore, successful product liabilityConsequently, claims brought against us, whether or not successful, could have a material adverse effect upon our business, financial condition, and results of operations.

Our stock price may be volatile and the value of an investment in our stock could be diminished.
The market price for our common stock has been affected and may continue to be affected by a number of factors, including:
Uncertain global and regional economic and geopolitical conditions, including slow or stagnant growth, inflationary pressures, political or military unrest
Failure to meet our forecasts or the expectations and forecasts of securities analysts
Changes in our guidance or announced forecasts that may or may not be consistent with the expectations of analysts or investors
Quarterly variations in our or our competitors' results of operations and changes in market share
The announcement of new products, product enhancements, or partnerships by us or our competitors
Our ability to develop, introduce, ship, and support new products and product enhancements and manage product transitions and recalls, if any
Repurchases of our common shares under our repurchase plans or public announcement of our intention not to repurchase our common shares
Our decision to declare dividends or increase or decrease dividends over historical rates
The loss of services of one or more of our executive officers or other key employees
Changes in earnings estimates, recommendations, or ratings by securities analysts or a reduction in the number of analysts following our stock
Developments in our industry, including new or increased enforcement of existing governmental regulations related to our products and new or revised communications standards
Concentrated ownership of our common stock by a limited number of institutional investors that may limit liquidity for investors interested in acquiring or selling positions in our common stock, particularly substantial positions
Sales of substantial numbers of shares of our common stock in the public market by us, our officers or directors, or unaffiliated third parties, including institutional investors
General economic, political, and market conditions, including market volatility
Litigation brought by or against us
Other factors unrelated to our operating performance or the operating performance of our competitors

Our business could be materially adversely affected if we lose the benefit of the services of key personnel or if we fail to attract talented new personnel.
Our success depends to a large extent upon the services of a limited number of executive officers and other key employees. The unanticipated loss of the services of one or more of our executive officers or key employees could have a material adverse effect upon our business, financial condition, and results of operations. We also believe that our future success will depend in large part upon our ability to attract and retain additional highly skilled technical, management, sales, and marketing personnel. Competition for such personnel is intense. We may not be successful in attracting and retaining such personnel, and our failure to do so could have a material adverse effect on our business, operating results, or financial condition.

We are subject to environmental laws and regulations that expose us to a number of risks and could result in significant liabilities and costs.
There are multiple regulatory initiatives in several jurisdictions regarding the removal of certain potential environmentally sensitive materials from our products to comply with Restrictions of the use of Certain Hazardous Substances in Electrical and Electronic Equipment (“RoHS”) and on Waste Electrical and Electronic Equipment (“WEEE”).  If it is determined that our products do not comply with RoHs or WEEE, or additional new or existing environmental laws or regulations in the U.S., Europe, or other jurisdictions are enacted or amended, we may be required to modify some or all of our products or replace one or more components in those products, which, if such modifications are possible, may be time-consuming, expensive to implement or decrease end-user demand, particularly if we increase prices to offset higher costs. If any of the foregoing were to happen, our ability to sell one or more of our products may be limited or prohibited causing a material negative effect on our financial results.
We are subject to various federal, state, local, and foreign environmental laws and regulations, including those governing the use, discharge, and disposal of hazardous substances in the ordinary course of our manufacturing process. It is possible that future environmental legislation may be enacted or current environmental legislation may be interpreted in any given country in a manner that creates environmental liability with respect to our facilities, operations, or products.  We may also be required to implement new or modify existing policies, processes and procedures as they relate to the use and disposal of our products. To the extent any new or modified policies, processes or procedures are difficult, time-consuming or costly to implement or we incur claims for environmental matters exceeding reserves or insurance for environmental liability, our operating results could be negatively impacted.
We have $16.1$15.8 million of goodwill and other intangible assets recorded on our balance sheet.  If the carrying value of our goodwill were to exceed its implied fair value, or if the carrying value of intangible assets were not recoverable, an impairment loss may be recognized, which would adversely affect our financial results.
As a result of past acquisitions we have $16.1$15.8 million of goodwill and other intangible assets on our consolidated balance sheet as of March 31, 2015.2016.  It is impossible at this time to determine if any future impairment charge could occur or, if it does, whether such charge related to these assets would be material. If such a charge is necessary, it may have a material adverse effect our financial results.
If we are unable to protect our information systems against service interruption, misappropriation of data or breaches of security, our operations could be disrupted, our reputation may be damaged, and we may be financially liable for damages.
We rely on networks, information systems, and other technology (“information systems”), including the Internet and third-party hosted services, to support a variety of business activities, including procurement, manufacturing, sales, distribution, invoicing, and collections. We use information systems to process and report financial information internally and to comply with regulatory reporting. In addition, we depend on information systems for communications with our suppliers, distributors, and customers. Consequently, our business may be impacted by system shutdowns or service disruptions during routine operations, such as system upgrades or user errors, as well as network or hardware failures, malicious software, hackers, natural disasters, communications interruptions, or other events (collectively, "network incidents"). Our computer systems have been, and will likely continue to be, subject to network incidents. While, to date, we have not experienced a network incident resulting in material impairment to our operations, nor have we experienced material intentional or inadvertent disclosure of our data or information or the information or data of our customers or vendors, future network incidents could result in unintended disruption of our operations or disclosure of sensitive information or assets. Furthermore, we may experience targeted attacks and although we continue to invest in personnel, technologies, and training to prepare for and reduce the adverse consequences of such attacks, these investments are expensive and do not guarantee that such attacks will be unsuccessful, either completely or partially.
If our information systems are disrupted or shutdown and we fail to timely and effectively resolve the issues, we could experience delays in reporting our financial results and we may lose revenue and profits. Misuse, leakage, or falsification of information could result in a violation of data privacy laws and regulations, damage our reputation, and have a negative impact on net operating results. In addition, we may suffer financial damage and damage to our reputation because of loss or misappropriation of our confidential information or assets, or those of our partners, customers, or suppliers. We could also be required to expend significant effort and incur financial costs to remedy security breaches or to repair or replace networks and information systems.

War, terrorism, public health issues, natural disasters, or other business interruptions could disrupt supply, delivery, or demand of products, which could negatively affect our operations and performance.
War, terrorism, public health issues, natural disasters, or other business interruptions, whether in the U.S. or abroad, have caused or could cause damage or disruption to international commerce by creating economic and political uncertainties that may have a strong negative impact on the global economy, us, and our suppliers or customers.  Our major business operations and those of many of our vendors and their sub-suppliers (collectively, "Suppliers") are subject to interruption by disasters, including, without limitation, earthquakes, floods, and volcanic eruptions or other natural or manmade disasters, fire, power shortages, terrorist attacks and other hostile acts, public health issues, flu or similar epidemics or pandemics, and other events beyond our control and the control of our Suppliers.  
Our corporate headquarters, information technology, manufacturing, certain research and development activities, and other critical business operations are located near major seismic faults or flood zones.  While we are partially insured for earthquake-related losses or floods, our operating results and financial condition could be materially affected in the event of a major earthquake or other natural or manmade disaster.
Should any of the events above arise we could be negatively impacted by the need for more stringent employee travel restrictions, limitations in the availability of freight services, governmental actions limiting the movement of products between various regions, delays in production, and disruptions in the operations of our Suppliers.  Our operating results and financial condition could be adversely affected by these events.
Provisions in our charter documents and Delaware law or a decision by our Board of Directors in the future may delay or prevent a third party from acquiring us, which could decrease the value of our stock.
Our Board of Directors has the authority to issue preferred stock and to determine the price, rights, preferences, privileges and restrictions, including voting and conversion rights, of those shares without any further vote or action by the stockholders. The issuance of our preferred stock could have the effect of making it more difficult for a third party to acquire us. In addition, we are subject to the anti-takeover provisions of Section 203 of the Delaware General Corporation Law, which could also have the effect of delaying or preventing our acquisition by a third party. Further, certain provisions of our Certificate of Incorporation and bylaws could delay or make more difficult a merger, tender offer or proxy contest, which could adversely affect the market price of our common stock.

ITEM 3.  LEGAL PROCEEDINGS

On October 12, 2012, GN Netcom, Inc. sued Plantronics, Inc. in the U.S. District Court for the District of Delaware, case number 1:12cv01318, alleging violations of the Sherman Act, the Clayton Act, and Delaware common law. In its complaint, GN specifically alleges four causes of action: Monopolization, Attempted Monopolization, Concerted Action in Restraint of Trade, and Tortious Interference with Business Relations. GN claims that Plantronics dominates the market for headsets sold into contact centers in the United States and that a critical channel for sales of headsets to contact centers is through a limited network of specialized independent distributors (“SIDs”). GN asserts that Plantronics attracts SIDs through Plantronics Only Distributor Agreements and the use of these agreements is allegedly illegal. Plantronics denies each of the allegations in the complaint and is vigorously defending itself. See Note 8, Commitments and Contingencies, of our Notes to Consolidated Financial Statements in this Form 10-K.

During the quarter ended December 26, 2015, GN Netcom (“GN”) and Plantronics commenced the briefing on a motion for sanctions against Plantronics for spoliation of evidence. The briefing was concluded in early January. A court date for a hearing on the motion for sanctions is scheduled for May 18, 2016. There exists a reasonable possibility of the court issuing a sanction; however, we believe the low end of the possible range of losses is zero and the upper end of the range is immaterial. In the event we were to incur other, non-monetary sanctions for spoliation of evidence, it may have an adverse impact on the substantive case brought against us on October 12, 2012. However, we are unable to estimate a loss or range of losses that could possibly result from the substantive case should non-monetary sanctions be brought against us.

In addition, we are presently engaged in various legal actions arising in the normal course of business.  We believe it is unlikely that any of these actions will have a material adverse impact on our operating results; however, because of the inherent uncertainties of litigation, the outcome of any of these actions could be unfavorable and could have a material adverse effect on our financial condition, results of operations, or cash flows.

We initiated a restructuring plan during the third quarter of fiscal year 2016. Under the plan, we reduced costs by eliminating certain positions in the US, Mexico, China, and Europe. The pre-tax charges of $16.2 million incurred during fiscal year 2016 were incurred for severance and related benefits. During fiscal year 2016, we recognized gains from litigation of $1.2 million, due primarily to a payment by a competitor to dismiss litigation involving the alleged infringement of a patent assigned to us.

During fiscal year 2015, we recognized a gain of $6.5 million upon payment by a competitor to dismiss litigation involving the alleged infringement of a patent assigned to us. In addition, we recognized a gain of $2.2 million related to the resolution of an insurance coverage dispute with one of its insurance carriers.

We initiated a restructuring plan during the third quarter of fiscal year 2013. Under the plan, we reallocated costs by eliminating certain positions in the US, Mexico, China, and Europe, and transitioned some of these positions to lower cost locations. As part of this plan, we also vacated a portion of a leased facility at our corporate headquarters in the first quarter of fiscal year 2014. The pre-tax charges incurred during fiscal year 2013 included $1.9 million for severance and related benefits and an immaterial amount of accelerated amortization on leasehold assets with no alternative future use. We incurred an immaterial amount of lease termination costs when we exited the facility in the first quarter of fiscal year 2014. The restructuring plan was substantially complete at the end of the first quarter of fiscal year 2014.

During fiscal year 2011, we recognized a gain of $5.1 million upon payment by a competitor to dismiss litigation involving the alleged theft of certain trade secrets. In addition, we recorded $1.4 million in accelerated amortization expense to reflect the revised estimated life of an intangible asset we deemed to be abandoned.

ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
The following discussion and analysis is intended to help you understand our results of operations and financial condition. It is provided as a supplement to, and should be read in conjunction with, our Consolidated Financial Statements and related notes thereto included elsewhere in this report.  This discussion contains forward-looking statements.  Please see the sections entitled "Certain Forward Looking Information" and "Risk Factors" above for discussions of the uncertainties, risks, and assumptions associated with these statements.  Our fiscal year-end financial reporting periods end on the Saturday closest to March 31st.  Fiscal year 2016 had 53 weeks and ended on April 2, 2016, fiscal years 2015, and 2014, and 2013 each had 52 weeks and ended on March 28, 2015, and March 29, 2014, and March 30, 2013, respectively.  For purposes of presentation, we have indicated our accounting fiscal year as ending on March 31.

OVERVIEW
 
We are a leading designer, manufacturer, and marketer of lightweight communications headsets, telephone headset systems, other communication endpoints, and accessories for the worldwide business and consumer markets under the Plantronics brand.  In addition, we manufacture and market specialty telephone products under our Clarity brand, such as telephones for the hearing impaired, and other related products for people with special communication needs. Our major product categories are Enterprise, which includes headsets optimized for Unified Communications (“UC”), other corded and cordless communication headsets, audio processors, and telephone systems; and Consumer, which includes Bluetooth®Bluetooth and corded products for mobile phonedevice applications, personal computer ("PC") and gaming headsets, and specialty products marketed for hearing impaired individuals.

Our priorities during fiscal year 2015 were to deliver profitable growth, extend our brand, expand our consumer reach, scale for growth, and optimize our culture.

Despite macroeconomic headwinds in some of our key markets, we achieved solid financial results. Compared to the prior year, net revenues decreased 0.9% to $856.9 million. The decrease in net revenues was driven by lower revenues within our Consumer product category, which declined 6.3% from the prior year. This decline was partially offset by slight growth in our Enterprise product category, which increased 5.7%1.2% from the prior year. While our primary driver of revenue growth continues to $865.0be revenues from the sale of our UC products, our  fiscal year 2016 Consumer revenues were negatively impacted by $22 million whiledue to the rapid decline of the U.S. market for mono Bluetooth headsets. However, we believe we grew our market share in this category, which helped to partially offset the decline. Our fiscal year 2016 revenues were also negatively impacted by fluctuations in foreign currency exchange rates. Compared to the other foreign currencies in which we sell, a stronger U.S. Dollar ("USD") decreased net revenues by approximately $27 million, net of the effects of hedging, in our fiscal year 2016 compared to the prior year.

Operating profit decreased 27.5% to $108.0 million, due primarily to restructuring charges taken during fiscal year 2016, the fluctuations in foreign currency exchange rates, and the impact of a non-recurring, favorable litigation settlement in fiscal year 2015. The adverse fluctuations in foreign currency exchange rates negatively impacted our net revenues but favorably impacted our operating profit grew 6.4%expenses, although to $149.1 million.a lesser degree, for a net unfavorable impact of $11 million to our operating profit. These items were partially offset by a reduction in variable compensation expense due to lower profitability. We delivered $112.3$68.4 million in net income, representing approximately 13%8.0% of our net revenues. UC product revenues, which we believe represent our key long-term growth driver, increased 18.4% over the prior year to $196.2 million.

To extendWe generate approximately 40% to 45% of our brand inrevenues from international sales; therefore, the Enterprise market, we continued to build strategic alliances with major UC vendors and increasedimpact of currency movements on our investments in future products targeted at the UC and contact center categories. We enhanced our Channel-facing go-to-market programs and achieved important milestones, including cumulative sales of more than 5 million audio devices optimized for Microsoft Lync. This achievement demonstrates that businesses trust Plantronics to deliver high-quality audio for voice and video communications, enabling end-users to collaborate, anytime and anywhere.net revenues can be significant. In addition, in some international locations where we sell in USD, we also face additional pricing pressure, discounting, and lost business as the stronger dollar negatively impacts buying decisions. Unfavorable impacts from the global economy and consumer spending together with exchange rate fluctuations could continue to negatively impact our current portfolio of solutions qualified on Lync 2013 is fully compatible and certified for use with Microsoft's new Skype for Business (formerly Lync) UC client.

To expand our consumer reach,net revenues in our fiscal year 2015 product development roadmap included new product launches such2017. We continually work to offset currency movements through hedging strategies designed to minimize the volatility of results and dampen large fluctuations. However, as our revenue hedging instruments cover a period of up to 12 months, the BackBeat Pro, targeted towardhedging conducted a year ago is expected to deliver little benefit to offset the fastest-growing subset of the consumer headset market, the stereo Bluetooth market. Additionally, we strengthened our leading position in the mono Bluetooth category with the release of the Voyager Edge. We also accelerated development efforts for additional new Consumer products to be launchedstronger dollar against other major currencies in fiscal year 20162017.

Revenues from our Consumer products channel are seasonal and beyond, includingtypically strongest in our third fiscal quarter, which includes the majority of the holiday shopping season. Additionally, other factors directly impact our Consumer product category performance, such as consumer preferences, changes in consumer confidence and other macroeconomic factors, product life-cycles (including the introduction and pace of adoption of new technology), and the competitive retail environment. Our Consumer business continues to be impacted by a refresh ofdecline in sales volumes in our PC and Entertainment product line plannedmono Bluetooth products as the market for these products contracts. The unit volumes in our stereo Bluetooth category increased slightly when compared to the coming year. We have followed our business customer into the mobile world with the goal of becoming the indispensable interface users turn to for connected experiences throughout their day. Duringprior fiscal year, 2015 we gained share in the mono Bluetooth category and achieved strong growth in the stereo Bluetooth category. In fiscal year 2015, we were presented with four International Forum (iF) product design awards for both Enterprise and Consumerdriven primarily by our newer generation of products. We anticipate that these newer products and two Consumer Electronics Show (CES) innovation awards. We anticipate thatother planned investments in the Consumer category will help positionallow us to maintain or grow market share as opportunitiesbetter compete in these consumer product categories as they continue to expand.

To scale for growth, While we implemented global process improvements, resulting in increased operational efficiencies. This was made possible by major capital investments inhave been building our infrastructure withstereo portfolio over the reimplementationlast several years, it is not yet as robust as our mono Bluetooth portfolio of our global enterprise resource planning ("ERP") system. We optimized our culture through investments in our workspaces around the world to enable smarter working and promote innovation, productivity, and employee well-being.products. As a result of these continued investments,market changes, we have reduced the amount we expect to invest in non-premium mono Bluetooth portfolio while shifting that investment toward additional stereo Bluetooth products. This shift toward entertainment solutions is important to our Tijuana manufacturing facility was votedlong-term brand position.


Due to slower than anticipated growth of UC revenues, combined with the best companynegative impact of a strengthening dollar, and a sharp decrease in the U.S. mono Bluetooth market, our fiscal year 2016 revenues declined year over year, causing us to workmake some necessary changes to reduce our cost structure. During the third quarter of fiscal year 2016 we initiated a restructuring plan to better align expenses to our revenue and gross margin profile and position us for improved operating performance. Under that plan, we reduced costs through voluntary and involuntary elimination of certain positions throughout the organization in the U.S., Mexico, for the fifth consecutive year.China, and Europe. The restructuring actions have resulted in pre-tax charges of approximately $16.2 million in our fiscal year 2016.

Looking forward to fiscal year 2016,2017, UC will continuecontinues to be our primary focus area. With the vast majority of the UC opportunity still ahead of us, we believe we are in the beginning stage of a potentially long period of growth. We believe UC represents our key long-term driver of revenue and profit growth, as we anticipate UC systems will become more commonly adopted by enterprises to reduce costs and improve collaboration. We believe growth of UC will increase overall headset adoption in enterprise environments, and we expect solutions featuring our Simply Smarter Communications® technology will be an important partmost of the UC landscape. Whilegrowth in our Enterprise product category over the next five years to come from headsets designed for UC.

In addition, in fiscal year 2017 we are expecting to launch new peripheral "as-a-service" offerings which we anticipate will complement our existing suite of product offerings as we move toward a hybrid business model of hardware, software, and services. We believe these enhanced offerings will allow us to expand the reach of our solutions portfolio and scale for growth. Our aim is to simplify our customers' experience and drive a baseline of experiences across our portfolio. During our fiscal year 2017, we will strive to transform data into actionable insights for our customers through software solutions that will offer reporting on asset management, usage, and conversation/acoustic health. In order to achieve these objectives, we will redefine our sales and marketing relationships and harmonize goals across these organizations to ensure we are working toward the same shared vision and go-to-market strategy.

We remain cautious about the macroeconomic environment, based on uncertainty around fiscal policy in the U.S., as well as broader economic uncertainty in many parts of Europe and Asia Pacific, which makes it difficult for us to gauge what impact the economy may have on our future business, and the fact that the UC opportunity has not matured as quickly as we initially anticipated, we will continue investing prudently in our long-term growth opportunities.anticipated. We will continue focusing onto monitor our expenditures and prioritize expenditures that further our strategic long-term growth opportunities such as innovative product development throughin our core research and development efforts.efforts, including the use of software and services as part of our portfolio. UC will also remain the central focus of our sales force, marketing group, and other customer service and support teams as we continue expandinginvesting in key strategic alliances and integrations with major UC vendors to market our UC products.  We believe we have an excellent position in the Enterprise and Consumer markets and a well-deserved reputation for quality and service that we will continually strive to earn through ongoing investment and strong execution.vendors.

Enterprise products represent our largest source of revenues, while Consumer products represent our largest unit volumes.  Net revenues may vary due to seasonality, the timing of new product introductions and discontinuation of existing products, discounts and other incentives, and channel mix. Net revenues derived from sales of Consumer products into the retail channel typically account for a seasonal increase in net revenues in the third quarter of our fiscal year.

Our net revenues decreased in fiscal year 2016 compared to fiscal year 2015 due largely to a decline in Consumer revenues, which was mainly attributable to the shrinking mono Bluetooth market. This decline was partially offset by slight growth in our Enterprise revenues driven by an increase in demand for UC products resulting from continued adoption of UC voice solutions in the marketplace, partially offset by a slight decline in Core Enterprise (non-UC products).


A stronger U.S. Dollar ("USD") compared to the other foreign currencies in which we sell decreased net revenues by approximately $27 million, net of the effects of hedging, in fiscal year 2016 compared to fiscal year 2015. We generate approximately 44% of our revenues from international sales; therefore, the impact of currency movements on our net revenues can be significant. In fiscal year 2017, our revenues may continue to be affected by uncertainty surrounding exchange rate fluctuations as well as the global economy and consumer spending.

Our net revenues increased in fiscal year 2015 compared to fiscal year 2014 due largely to growth in Enterprise revenues, which was mainly attributable to growth in demand for UC products driven by continued adoption of UC voice solutions in the marketplace. Growth in our net revenues from Consumer products was the result of continued success in the market of key products such as our Voyager Legend mono Bluetooth headset and our Backbeat GO2 and BackBeat FIT stereo Bluetooth headsets. In addition, we successfully introduced Voyager Edge and Backbeat PRO during our fiscal year 2015, driving incremental sales. Partly offsetting these increases were reductions in revenue from our PC and Entertainment product line as our portfolio awaitswas awaiting a refresh which began in the coming year.fiscal year 2016. A stronger U.S. Dollar ("USD") compared to the other foreign currencies in which we sell decreased net revenues by approximately $4.7$5 million, net of the effects of hedging, in fiscal year 2015 compared to fiscal year 2014. We generate approximately 40% of our revenues from international sales; therefore, the impact of currency movements on our net revenues can be significant. In fiscal year 2016, our revenues may be materially affected by the high level of uncertainty surrounding exchange rate fluctuations as well as the global economy and consumer spending. We continually work to offset currency movements through hedging strategies designed to minimize the volatility of results and dampen large fluctuations. However, significant and sustained currency moves cannot be managed by hedges alone.
Our net revenues increased in fiscal year 2014 compared to fiscal year 2013 driven by growth in Enterprise revenues, which was mainly attributable to growth in demand for UC products, although our non-UC Enterprise business also grew slightly. We also enjoyed growth in Consumer product revenues as a result of our stronger portfolio of mobile products, which drove strong double-digit growth in the Americas. A weaker USD compared to the Euro ("EUR") and British Pound Sterling ("GBP") increased net revenues by approximately $2.3 million in fiscal year 2014 compared to fiscal year 2013, net of the effects of hedging.

As a percentage of total net revenues, U.S. net revenues decreased slightly compared with international revenues in fiscal year 2016 compared to fiscal year 2015. The decrease in absolute dollars in U.S. net revenues was driven primarily by weaker Consumer revenues primarily as a result of the declining mono Bluetooth market, which was partially offset by increased Enterprise net revenues due to continued growth in demand for UC. The decrease in absolute dollars in international revenues was due primarily to decreased Core Enterprise net revenues, partially offset by higher UC and Consumer revenues. International revenues were reduced by approximately $27 million, net of the effects of hedging, in fiscal year 2016 compared to fiscal year 2015, due to unfavorable foreign exchange fluctuations in the other foreign currencies in which we sell.

As a percentage of total net revenues, U.S. net revenues decreased slightly compared with international revenues in fiscal year 2015 compared to fiscal year 2014, with international revenues, as a percentage of total net revenues, correspondingly increasing.2014. The increase in absolute dollars in U.S. net revenues was driven primarily by increased Enterprise net revenues due to continued growth in demand for UC and stronger Consumer revenues as a result of a refreshed and enhanced next generation product portfolio. The increase in absolute dollars in international revenues was also due primarily to increased Enterprise net revenues due toreflecting continued growth in demand for UC with higher Consumer revenues contributingproducts and, to a lesser extent.extent, higher Consumer revenues. International revenues were reduced by approximately $4.7$5 million, net of the effects of hedging, in fiscal year 2015 compared to fiscal year 2014, due to unfavorable foreign exchange fluctuations in the other foreign currencies in which we sell.

As a percentage of total net revenues, U.S. net revenues increased slightly in fiscal year 2014 compared to fiscal year 2013, with international revenues, as a percentage of total net revenues, correspondingly decreasing. The increase in absolute dollars in U.S. net revenues resulted in roughly equal measure from increased Enterprise net revenues due to continued growth in demand for UC and increased Consumer revenues as a result of an improved product portfolio. The increase in absolute dollars in international revenues was also due almost entirely to increased Enterprise net revenues due to continued growth in demand for UC. A weaker USD compared to the EUR and GBP resulted in increased international net revenues of approximately $2.3 million in fiscal year 2014 compared to fiscal year 2013, net of the effects of hedging.

Cost of Revenues and Gross Profit
 
Cost of revenues consists primarily of direct manufacturing and contract manufacturer costs, warranty expense, freight expense, depreciation, duty expense, reserves for excess and obsolete inventory, royalties, and an allocation of overhead expenses, including facilities, IT, and human resources costs.

Compared to the prior year, gross profit as a percentage of revenues decreased in fiscal year 2016 due primarily to the weakening of foreign currencies relative to the USD, which negatively impacted margins on our international product sales. Gross profit was further negatively impacted by a lower mix of Core Enterprise sales, which carry higher margins than our UC and Consumer categories.

Compared to the prior year, gross profit as a percentage of revenues increased in fiscal year 2015 due primarily to reductions in product costs and higher revenues from next-generation mobile products carrying better margins.  These favorable impacts were offset in part by the following:  (i) a shift in product mix from Enterprise to Consumer; (ii) within Enterprise, the continued ramp in UC, which carries lower margins than our non-UC Enterprise products; and (iii) non-recurrence of a favorable adjustment made in fiscal year 2014 to correct an immaterial error related to our warranty and sales returns reserves. Refer to further discussion of this prior year adjustment in Note 6, Details of Certain Balance Sheet Accounts, of the Notes to Consolidated Financial Statements in this Annual Report on Form 10-K.

The increase in gross profit in fiscal year 2014 compared to fiscal year 2013 was due primarily to the increase in net revenues. As a percentage of net revenues, gross profit decreased primarily from our UC revenues growing faster than our overall Enterprise revenues. Secondarily, revenues from Consumer products, which carry lower margins than our weighted average margin, grew faster than our overall revenues.

There are significant variances in gross profit percentages between our higher and lower margin products; therefore, small variations in product mix, which can be difficult to predict, can have a significant impact on gross profit.  Gross profit may also vary based on distribution channel, return rates, and other factors.

Research, Development, and Engineering
 
Research, development, and engineering costs are expensed as incurred and consist primarily of compensation costs, outside services, including legal fees associated with protecting our intellectual property, expensed materials, depreciation, and an allocation of overhead expenses, including facilities, IT, and human resources costs.

The decrease in research, development, and engineering expenses in fiscal year 2016 compared to fiscal year 2015 was due primarily to a reduction in variable compensation associated with lower profitability and a favorable impact due to foreign currency fluctuations. These items were partially offset by higher equity-based compensation expense resulting from restricted stock grants made after May 2013, which vest over three years, compared to restricted stock grants made prior to May 2013, which vest over four years.

The increase in research, development, and engineering expenses in fiscal year 2015 compared to fiscal year 2014 was due primarily to $4.7 million in headcount-related costs, including increased salary expense, and performance-based compensation, includingand an increase to equity-based compensation resulting from the shorter vesting schedule of restricted stock grants made after May 2013 which vest over three years, compared to restricted stock grants made prior to May 2013, which vest over four years.2013.

The increase in research, development and engineering expenses in fiscal year 2014 compared to fiscal year 2013 was due primarily to $4.0 million in headcount-related costs, including increased salary expense, and performance-based compensation, including an increase to equity-based compensation resulting from restricted stock grants made after May 2013, which vest over three years, compared to restricted stock grants made prior to May 2013, which vest over four years.

The decrease in selling, general, and administrative expenses in fiscal year 2016 compared to fiscal year 2015 was due primarily to a reduction in variable compensation expense associated with lower profitability, a favorable impact due to foreign currency fluctuations, and reduced legal, IT, and outside services expenses. These decreases were partially offset by higher equity-based compensation expense resulting from the shorter vesting schedule of restricted stock grants made after May 2013 compared to restricted stock grants made prior to May 2013, and an increase in bad debt expense related to RadioShack's bankruptcy proceedings.

The increase in selling, general, and administrative expenses in fiscal year 2015 compared to fiscal year 2014 was due primarily to $13.5 million in higher headcount-related costs resulting from higher performance-based compensation reflecting higher net revenues and higher overall achievement against targets, including an increase to equity-based compensation resulting from the shorter vesting schedule of restricted stock grants made after May 2013 compared to restricted stock grants made prior to May 2013. We also experienced an increase of $3.3 million in depreciation related to capital investments made in the past year and $7.1 million in higher legal expenses, driven mainly by ongoing litigation.

The increase in selling, general, and administrative expenses in fiscal year 2014 compared to fiscal year 2013 was due primarily to $12.7 million in higher costs resulting from increased headcount, mainly resulting from our investment in Plantronics' global sales presence, and from higher performance-based compensation, including sales commissions, reflecting higher net revenues and higher overall achievement against targets. We also made investments in marketing programs of $4.6 million, including product launch activities and brand awareness campaigns.

Gain from Litigation Settlements

During the fiscal year ended March 31, 2016 we recognized gains of approximately $1.2 million, net of immaterial legal contingency fees, within operating income. These gains were primarily the result of net receipts of $0.8 million from a competitor to dismiss litigation involving the alleged infringement of a patent assigned to us as well as miscellaneous immaterial settlements with other parties.

During the fiscal year ended March 31, 2015 we recognized gains of approximately $8.7 million, net of immaterial legal contingency fees, within operating income. These gains were the result of net receipts of $6.5 million from a competitor to dismiss litigation involving the alleged infringement of a patent assigned to us and $2.2 million related to the resolution of an insurance coverage dispute with one of our insurance carriers. There were no such gains for the fiscal year ended March 31, 2014.

In the third quarter of fiscal year 2016 we initiated a restructuring plan intended to streamline and focus our efforts in order to more closely align our cost structure with our projected future revenue streams, which will better position us for improved operating performance and profitability. This measure was taken as a part of a broader effort to optimize the organization around our long-term strategic initiatives while adjusting for current macroeconomic business conditions and involved the reduction of approximately 125 positions. These staff reductions were substantially complete by the end of fiscal year 2016.

In connection with this plan, we have recorded pre-tax charges of approximately $16.2 million, consisting of severance and related benefits. These charges were offset by a reduction in our fiscal year 2016 stock-based compensation expense of $1.5 million attributable to stock award forfeitures resulting from the restructuring action. Projected annual saving from this plan are in the range of approximately $15 to $16 million and will enable us to reduce our cost structure to better support our long-term profitability targets and maintain our competitiveness. See Note 11, Restructuring and Other Related Charges, of our Notes to Consolidated Financial Statements in this Form 10-K for further information on restructuring costs.

Interest Expense

Interest expense of $25.1 million for fiscal year 2016, was primarily related to the 5.50% Senior Notes and included $1.2 million in amortization of debt issuance costs. Interest expense for fiscal years 2015 and 2014 was immaterial and did not include such costs.

The effective tax rate for fiscal year 2016 is lower than that in the previous year due primarily to domestic interest expense on new debt and tax benefits associated with the unwind of prior cost-sharing of stock based compensation for the engineering function. A retroactive and permanent reinstatement of the federal research credit was signed into law on December 18, 2015. As such, our effective tax rate for fiscal year 2016 includes the benefit of one quarter of credits for fiscal year 2015 plus the tax benefit for the fiscal year 2016 tax credit.

The effective tax rate for fiscal year 2015 is higher than the previous year due primarily to the absence of several one-time, discrete items that benefited the tax rate in the previous year, such as the generation of a foreign tax credit carryover, changes in Mexican tax law that resulted in the reversal of a valuation allowance, and a deduction for qualifying domestic production activities. These factors were offset by a higher proportion of income earned in foreign jurisdictions that is taxed at lower rates and by an increase in the benefit from the U.S. federal research tax credit. Our fiscal year 2015 included four quarters of benefit from the U.S. federal research tax credit because the credit expired on December 31, 2014 but was retroactively reinstated in January 2015. In contrast, during our fiscal year 2014, the credit was only available for three quarters as the credit expired December 31, 2013 and was not renewed.

In comparison to fiscal year 2013, the decrease in the effective tax rate for fiscal year 2014 was due primarily to changes in Mexican tax law that resulted in the reversal of a valuation allowance, a deduction for qualifying domestic production activities, and the generation of a foreign tax credit carryover, offset by a decrease in the benefit from the U.S. federal research tax credit. The U.S. federal research tax credit expired December 31, 2013 and was therefore only available for three quarters in our fiscal year 2014, compared to fiscal year 2013, which included a five quarters of benefit due to the timing of the retroactive reinstatement of the credit. On January 2, 2013, the American Taxpayer Relief Act of 2012, which included a provision that retroactively extended the federal tax research credit to January 1, 2012 for two years, was signed into law. We recognized an approximate $1.8 million discrete tax benefit in the fourth quarter of fiscal year 2013 for the previously expired period from January 1, 2012 to December 31, 2012.

Our effective tax rate for fiscal years 2016, 2015, 2014, and 20132014 differs from the statutory rate due to the impact of foreign operations taxed at different statutory rates, income tax credits, state taxes, and other factors.  Our future tax rate could be impacted by a shift in the mix of domestic and foreign income, tax treaties with foreign jurisdictions, changes in tax laws in the U.S. or internationally, or a change in estimate of future taxable income, which could result in a valuation allowance being required.

We had $12.8$12.7 million of unrecognized tax benefits as of March 31, 20152016 compared to $12.6$12.8 million and $11.1$12.6 million as of March 31, 20142015 and 2013,2014, respectively. The unrecognized tax benefits as of the end of fiscal year 20152016 would favorably impact the effective tax rate in future periods, if recognized.

It is our continuing practice to recognize interest and/or penalties related to income tax matters in income tax expense. As of March 31, 2015,2016, we had approximately $1.8$1.6 million of accrued interest related to uncertain tax positions, compared to $1.71.8 million and $2.0$1.7 million as of March 31, 20142015 and 2013,2014, respectively. No penalties have been accrued.
  
The liability for uncertain tax positions may be reduced for liabilities that are settled with taxing authorities or on which the statute of limitations could expire without assessment from tax authorities.  Currently, we cannot reasonably estimate the amount of reductions, if any, during the next twelve months.

We use cash provided by operating activities as our primary source of liquidity. We expect that cash provided by operating activities will fluctuate in future periods as a result of a number of factors, including fluctuations in our revenues, the timing of product shipments during the quarter, accounts receivable collections, inventory and supply chain management, and the timing and amount of tax and other payments. 

Operating Activities
 
Net cash provided by operating activities during the year ended March 31, 2016 decreased from the prior year due primarily to lower net income after adjusting for non-cash items - predominantly the remeasurement of our non-designated hedge instruments, stock-based compensation, non-cash restructuring charges, and depreciation/amortization. These items were partially offset by a decrease in accounts receivable, and an increase in accounts payable both driven by a shorter cash conversion cycle.

Net cash provided by operating activities during the year ended March 31, 2015 increased from the prior year due primarily to higher net income after adjusting for non-cash items, predominantly stock-based compensation and depreciation, a decrease in accounts receivable, and an increase in accounts payable both due to improved working capital management. These items were partially offset by increase in current assets related to participant deferrals as part of our deferred compensation plan. Please refer to Note 5, Deferred Compensation of our Notes to Consolidated Financial Statements in this Form 10-K for more information regarding our deferred compensation plan.

Investing Activities
Net cash provided by operatingused for investing activities during the year ended March 31, 20142016 increased from the prior year ended March 31, 2015 due to higher net income after adjusting for non-cash items, primarily stock-based compensation and reserve requirements for excess and obsolete inventories, and a decrease in inventories resulting from higher shipments during the period as compared to the same periodan increase in the prior year, which was driven by increased sales, coupled with the depletionnet purchases of last time buy inventories. These increases were partially offset by a decreaseinvestments and an increase in accounts payable resulting primarily from the timing of payments in fiscal year 2014 compared to fiscal year 2013.capital expenditures.

Investing Activities
Net cash used for investing activities during the year ended March 31, 2015 decreased from the year ended March 31, 2014 due to a decrease in capital expenditures and an increase in the net cash received from sales of investments. Cash used for investing activities for the year ended March 31, 2015 does not include approximately $2.1 million of capital expenditures as the corresponding accruals were included within accounts payable at March 31, 2015 and therefore did not have an impact on cash flows for the period.

Net cash used for investing activities during the year ended March 31, 2014 decreased from the year ended March 31, 2013 due to a decrease in net cash used for purchases of investments, partially offset by an increase in capital expenditures related primarily to the purchase of a new manufacturing facility in Tijuana, Mexico and costs incurred to commence implementation of a new ERP system.


31


We anticipate our capital expenditures in fiscal year 20162017 to be approximately $30.0$25.0 million to $35.0$30.0 million, related to costs associated with the purchase and related construction of a new smarter working office for our European headquarters in the Netherlands as well as costs associated with building and leasehold improvements at our U.S. headquarters, the implementation of a manufacturing execution system at our facility in Mexico, and other IT-related expenditures. The remainder of the anticipated capital expenditures for fiscal year 20162017 consist primarily of capital investment in our manufacturing capabilities, including tooling for new products. We will continue to evaluate new business opportunities and new markets; as a result, our future growth within the existing business or new opportunities and markets may dictate the need for additional facilities and capital expenditures to support that growth.

Financing Activities 
 
Net cash used for financing activities during the year ended March 31, 2016 decreased from the year ended March 31, 2015 primarily driven by net proceeds received from issuance of the 5.50% Senior Notes partially offset by an increase in the level of common stock repurchases.

Net cash used for financing activities during the year ended March 31, 2015 increased from the year ended March 31, 2014 due to an increase in the level of common stock repurchases and an increase in our quarterly dividend beginning in the first quarter of our fiscal year 2015. These items were partially offset by an increase in proceeds from our revolving line of credit.

Net cash used for financing activities during the year ended March 31, 2014 increased from the year ended March 31, 2013 due to an increase in the level of common stock repurchases and a net decrease in proceeds from issuances of stock under equity plans. This increase was partially offset by a decrease in repayments on our revolving line of credit, which we paid off in full in the fourth quarter of fiscal year 2013.

On April 27, 2015,May 3, 2016, we announced that our Audit Committee of the Board of Directors ("the Audit Committee") had declared a cash dividend of $0.15 per share of our common stock, payable on June 10, 20152016 to stockholders of record at the close of business on May 20, 2015.2016.  We expect to continue paying a quarterly dividend of $0.15 per share of our common stock; however, the actual declaration of dividends and the establishment of record and payment dates are subject to final determination by the Audit Committee each quarter after its review of our financial performance and financial position.

Liquidity and Capital Resources
 
Our primary discretionary cash uses have historically been for repurchases of our common stock and dividend payments.  At March 31, 20152016, we had working capital of $487.8 million, including $395.3 million of cash, cash equivalents, and short-term investments, compared to working capital of $507.8 million, including $374.7 million of cash, cash equivalents, and short-term investments compared to working capital of $458.7 million, including $335.4 million of cash, cash equivalents, and short-term investments at March 31, 20142015.  The increasedecrease in working capital at March 31, 20152016 compared to March 31, 20142015 results from the decrease in accounts receivable and increase in accounts payable both due primarily to improved working capital management.

Our cash and cash equivalents as of March 31, 20152016 consist of bank deposits with third party financial institutions, Commercial Paper, and Commercial Paper.Corporate Bonds.  We monitor bank balances in our operating accounts and adjust the balances as appropriate.  Cash balances are held throughout the world, including substantial amounts held outside of the U.S.  As of March 31, 20152016, of our $374.7395.3 million of cash, cash equivalents, and short-term investments, $16.3$40.9 million is held domestically while $358.4$354.4 million is held by foreign subsidiaries, approximately 90% of which were based in U.S. dollar-denominated holdings. The costs to repatriate our foreign earnings to the U.S. would likely be material; however, our intent is to indefinitely reinvest our earnings from foreign operations, and our current plans do not require us to repatriate them to fund our U.S. operations as we generate sufficient domestic operating cash flow and have access to external funding under our current revolving line of credit. Our investments are intended to establish a high-quality portfolio that preserves principal and meets liquidity needs.  As of March 31, 20152016, our investments are composed of Mutual Funds, US Treasury Notes, Government Agency Securities, Commercial Paper, Corporate Bonds, and Corporate Bonds.Certificates of Deposits ("CDs").

As of March 31, 20152016, there remained a total of 2,711,052634,011 shares authorized for repurchase under the stock repurchase program approved by the Board on March 4, 2015.January 29, 2016. Refer to Note 1112, Common Stock Repurchases, of our Notes to Consolidated Financial Statements in this Form 10-K for more information regarding our stock repurchase programs.

We had no retirements of treasury stock in fiscal year 2015. On January 2, 2013, we retired 5,398,376 shares of treasury stock which were returned to the status of authorized but unissued shares. These were non-cash equity transactions under which the cost of the reacquired shares was recorded as a reduction to both retained earningsyears 2016, 2015, and treasury stock.2014.

In May 2011,2015, we entered into aan Amended and Restated Credit Agreement (the “Credit Agreement”) with Wells Fargo Bank, National Association ("the Bank"(the “Bank”),. The Credit Agreement amended and restated our prior credit agreement, dated as most recently amended in March 2015 (as amended, "theof May 2011. The Credit Agreement") to increase our outstanding $100Agreement provides for a $100.0 million unsecured revolving credit facility ("the line of credit") by an additional $100 million, for a total facility of $200 million. Any outstanding principal, together with accrued and unpaid interest, is due on the amended maturity date of May 9, 2018 andto augment our financial flexibility. Our obligations under the Credit Agreement are required to be guaranteed by ourthe Company’s domestic subsidiaries, subject to certain exceptions.

In May 2016, we executed a First Amendment to Amended and Restated Credit Agreement and Limited Waiver (the “Amended Credit Agreement”). The Amended Credit Agreement extends the term of the Credit Agreement by one year to May 9, 2019, and waives a default under the Credit Agreement in effect as of March 31, 2016 in which our debt to EBITDA ratio minimally exceeded the previously agreed upon ratio of 3:1. The breach of the covenant was primarily a result of our restructuring activities in the third and fourth quarters of fiscal year 2016.

Revolving loans under the Amended Credit Agreement will bear interest, at our election, at (i) the Bank’s announced prime rate less 1.20% per annum or (ii) a daily one-month LIBOR rate plus 1.40% per annum. Principal, together with all accrued and unpaid interest, on the revolving loans is due and payable on May 9, 2019. The Company is also obligated to pay a commitment fee of 0.37% per annum on the average daily unused amount of the revolving line of credit, which fee shall be payable quarterly in arrears. The Company may prepay the loans and terminate the commitments under the Amended Credit Agreement at any time, without premium or penalty, subject to the reimbursement of certain costs. As of March 31, 2015 we2016 the Company had $34.5 million inno outstanding borrowings under the line of credit. Loans under the Credit Agreement bear interest at our election (1) at the Bank's announced prime rate less 1.50% per annum, (2) at a daily one month LIBOR rate plus 1.10% per annum, or (3) at an adjusted LIBOR rate, for a term of one, three or six months, plus 1.10% per annum.
The line of credit requires us to comply with the following two financial covenant ratios, in each case at each fiscal quarter end and determined on a rolling four-quarter basis:

Maximummaximum ratio of funded debt to earnings before interest, taxes, depreciation and amortization ("EBITDA"); and,
Minimumminimum EBITDA coverage ratio, which is calculated as EBITDAinterest payments divided by interest paymentsEBITDA.

We were in compliance with these financial covenant ratios as of March 31, 2015.

In addition, we and our subsidiaries are required to maintain on a consolidated basis, unrestricted cash, cash equivalents and marketable securities plus availability under the Amended Credit Agreement at the end of each fiscal quarter of at least $200.0$300.0 million. The lineAmended Credit Agreement contains customary events of credit contains affirmative covenants, including covenants regarding the payment of taxes and other liabilities, maintenance of insurance, reporting requirements, and compliance with applicable laws and regulations. The line of credit also contains negative covenants,default that include, among other things, limiting our ability to incur debt, make capital expenditures, grant liens, make acquisitions, and make investments. The events of default under the line of credit include payment defaults, crosscovenant defaults, cross-defaults with certain other indebtedness, breaches of covenants, judgment defaults, and bankruptcy and insolvency events involving us or anydefaults, and judgment defaults. The occurrence of an event of default could result in the acceleration of the obligations under the Amended Credit Agreement. As of March 31, 2016, we were in breach of our subsidiaries. As of March 31, 2015, we weredebt to EBITDA ratio covenant but in compliance with all other ratios and covenants underby a substantial margin.

On May 2, 2016, we received a waiver from the linelender for noncompliance with the minimum EBITDA covenant at March 31, 2016. Pursuant to the terms of credit.the waiver and amendment to the Credit Agreement, the $16.2 million of restructuring charges recorded in our fiscal year 2016 will be excluded from the lender’s rolling four-quarter EBITDA calculation.  This exclusion of restructuring charges does not automatically extend to any such future charges, should they be incurred.

This breach is not considered to be a cross-default on our 5.50% Senior Notes and as such has no impact on the amount or timing of amounts payable related to these debt instruments.

Our liquidity, capital resources, and results of operations in any period could be affected by repurchases of our common stock, dividend payments,the payment of cash dividends, the exercise of outstanding stock options, restricted stock grants under stock plans, and the issuance of common stock under our employee stock purchase plan ("ESPP").ESPP.  We receive cash from the exercise of outstanding stock options under our stock plan and the issuance of shares under our ESPP; however,ESPP. However, the resulting increase in the number of outstanding shares from these equity grants and issuances could affect our earnings per share. We cannot predict the timing or amount of proceeds from the sale or exercise of these securities or whether they will be exercised, forfeited, canceled, or expire unexercised.will expire. 


33


Based on past performance and current expectations, weWe believe that our current cash and cash equivalents, short-term investments, cash provided by operations, and the availability of additional funds under the Amended Credit Agreement will be sufficient to support business operations, capital expenditures, contractual obligations, and other liquidity requirements associated with ourfund operations for at least the next twelve months. However,12 months; however, any projections of future financial needs and sources of working capital are subject to uncertainty.  See “Certain Forward-Looking Information”Readers are cautioned to review the risks, uncertainties, and “Risk Factors”assumptions set forth in this Annual Report on Form 10-K, including the sections entitled “Certain Forward-Looking Information” and “Risk Factors” for factors that could affect our estimates for future financial needs and sources of working capital.



OFF BALANCE SHEET ARRANGEMENTS AND CONTRACTUAL OBLIGATIONS
 
We have not entered into any transactions with unconsolidated entities whereby we have financial guarantees, subordinated retained interests, derivative instruments, or other contingent arrangements that expose us to material continuing risks, contingent liabilities, or any other obligation under a variable interest in an unconsolidated entity that provides us with financing and liquidity support, market risk, or credit risk support.

A substantial portion of the raw materials, components, and subassemblies used in our products are provided by our suppliers on a consignment basis. These consigned inventories are not recorded on our consolidated balance sheet until we take title to the raw materials, components, and subassemblies, which occurs when they are consumed in the production process. Prior to consumption in the production process, our suppliers bear the risk of loss and retain title to the consigned inventory. The terms of the agreements allow the Company to return parts in excess of maximum order quantities to the suppliers at the supplier’s expense. Returns for other reasons are negotiated with the suppliers on a case-by-case basis and to date have been immaterial. If our suppliers were to discontinue financing consigned inventory, it would require us to make cash outlays and we could incur expenses which, if material, could negatively affect our business and financial results. As of March 31, 20152016 and 20142015, we had off-balance sheet consigned inventories of $33.4$41.1 million and $40.0$33.4 million, respectively.

Operating Leases

We lease certain facilities under operating leases expiring through our fiscal year 2025.2026. Certain of these leases provide for renewal options for periods ranging from one to three years and in the normal course of business, we may exercise the renewal options.

Unconditional Purchase Obligations

We utilize several contract manufacturers to manufacture raw materials, components, and subassemblies for our products. We provide these contract manufacturers with demand information that typically covers periods up to 13 weeks, and they use this information to acquire components and build products. We also obtain individual components for our products from a wide variety of individual suppliers. Consistent with industry practice, we acquire components through a combination of purchase orders, supplier contracts, and open orders based on projected demand information. As of March 31, 20152016, we had outstanding off-balance sheet third-party manufacturing commitments and component purchase commitments of $123.0150.9 million, all of which we expect to consume in the normal course of business.

Unrecognized Tax Benefits

As of March 31, 2015,2016, long-term income taxes payable reported on our consolidated balance sheet included unrecognized tax benefits and related interest of $12.812.7 million and $1.8$1.6 million, respectively.  We are unable to reliably estimate the timing of future payments related to unrecognized tax benefits and they are not included in the contractual obligations table above.  We do not anticipate any material cash payments associated with our unrecognized tax benefits to be made within the next twelve months.

CRITICAL ACCOUNTING ESTIMATES
 
Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP"). In connection with the preparation of our financial statements, we are required to make assumptions and estimates about future events, and apply judgments that affect the reported amounts of assets, liabilities, revenue, expenses and the related disclosures. We base our assumptions, estimates and judgments on historical experience, current trends, future expectations and other factors that management believes to be relevant at the time our consolidated financial statements are prepared. On an ongoing basis, we review the accounting policies, assumptions, estimates and judgments to ensure that our consolidated financial statements are presented fairly and in accordance with U.S. GAAP. Because future events and their effects cannot be determined with certainty, actual results could differ from our assumptions and estimates, and such differences could be material.

Our significant accounting policies are discussed in Note 2, Significant Accounting Policies, of the Notes to Consolidated Financial Statements in this Annual Report on Form 10-K. We believe the following accounting estimates are the most critical to aid in fully understanding and evaluating our reported financial results, and they require our most difficult, subjective, or complex judgments, resulting from the need to make estimates about the effect of matters that are inherently uncertain. We have reviewed these critical accounting estimates and related disclosures with the Audit Committee.

Revenue Recognition and Related Allowances
Inventory Valuation
Product Warranty Obligations
Income Taxes

Revenue Recognition and Related Allowances
 
We sell substantially all of our products to end users through distributors, retailers, and carriers. The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, and collection is reasonable assured. For most of the Company’s product sales, these criteria are met at either the time the product is shipped or the customer has received the product. Commercial distributors and retailers represent our largest sources of net revenues. Sales through our distribution and retail channels are made primarily under agreements allowing for rights of return and include various sales incentive programs, such as rebates, advertising, price protection, and other sales incentives. We have an established sales history for these arrangements and we record the estimated reserves and allowances at the time the related revenue is recognized. Customer sales returns are estimated based on historical data, relevant current data, and the monitoring of inventory build-up in the distribution channel.

The primary factors affecting our reserve for estimated customer sales returns include the general timing of historical returns and estimated return rates. The allowance for sales incentive programs is based on contractual terms and historical experience in the form of payments or sell-through credits redeemed by our customers. Future market conditions or an evaluation of partner incentives may lead us to increase customer incentive offerings, possibly resulting in an incremental reduction of revenue.

We have not made any material changes in the accounting methodology we use to measure sales return reserves or incentive allowances during the past three fiscal years. Substantially all credits associated with these activities are processed within the following fiscal year, and therefore, do not require subjective long-term estimates; however, if actual results are not consistent with the assumptions and estimates used, we may be exposed to losses or gains that could be material. If we increased our estimate as of March 31, 20152016 by a hypothetical 10%, our sales returns reserve and sales incentive allowance would have increased by approximately $0.6$0.7 million and $1.5$1.2 million, respectively. Net of the estimated value of the inventory that would be returned, this would have decreased gross profit and net income by approximately $2.1$4.0 million and $1.6$3.3 million, respectively.

When a sales arrangement contains multiple elements, such as hardware and software products and/or services, we allocate revenue to each element based on relative selling prices. The selling price for a deliverable is based on its vendor specific objective evidence ("VSOE"), if available, third party evidence ("TPE") if VSOE is not available, or estimated selling price ("ESP") if neither VSOE nor TPE are available. In multiple element arrangements where more-than-incidental software deliverables are included, we allocate revenue to each separate unit of accounting for each of the non-software deliverables and to the software deliverables as a group using the relative selling prices of each of the deliverables in the arrangement based on the aforementioned selling price hierarchy. Revenue recognized for the software portion of multiple element arrangements was less than 1% of total net revenues for the years ended March 31, 20152016 and 2014.2015. As of March 31, 20152016 and 2014,2015, total deferred revenue related to the software portion of multiple-element arrangements was $2.0$2.7 million and $3.0$2.0 million, respectively.


35


Inventory Valuation

Inventories are valued at the lower of cost or market.  The Company writes down inventories that have become obsolete or are in excess of anticipated demand or net realizable value. Our estimate of write downs for excess and obsolete inventory is based on a detailed analysis of on-hand inventory and purchase commitments in excess of forecasted demand. Our products require long-lead time parts available from a limited number of vendors and, occasionally, last-time buys of raw materials for products with long lifecycles. The effects of demand variability, long-lead times, and last-time buys have historically contributed to inventory write-downs.  Our demand forecast considers projected future shipments, market conditions, inventory on hand, purchase commitments, product development plans and product life cycle, inventory on consignment, and other competitive factors.  Refer to "Off Balance Sheet Arrangements" in this Annual Report on Form 10-K for additional details regarding consigned inventories.

We have not made any material changes in the accounting methodology we use to estimate our inventory write-downs or adverse purchase commitments during the past three fiscal years. If the demand or market conditions for our products are less favorable than forecasted or if unforeseen technological changes negatively impact the utility of our inventory, we may be required to record additional inventory write-downs or adverse purchase commitments, which would negatively affect our results of operations in the period the write-downs or adverse purchase commitments were recorded. If we increased our inventory reserve and adverse purchase commitment reserve estimates as of March 31, 20152016 by a hypothetical 10%, the reserves and cost of revenues would have each increased by approximately $0.6$0.4 million and our net income would have been reduced by approximately $0.5$0.4 million.

Product Warranty Obligations

The Company records a liability for the estimated costs of warranties at the time the related revenue is recognized. Factors that affect the warranty obligation include historical and projected product failure rates, estimated return rates, material usage, service related costs incurred in correcting product failure claims, and knowledge of specific product failures that are outside of the Company’s typical experience. If actual results are not consistent with our estimates or assumptions, we may be exposed to losses or gains that could be material. If we increased our warranty obligation estimate as of March 31, 20152016 by a hypothetical 10%, our obligation and the associated cost of revenues would have each increased by approximately $0.8$0.9 million and our net income would have been reduced by approximately $0.6 million.

Income Taxes

We are subject to income taxes in the U.S. and foreign jurisdictions and our income tax returns are periodically audited by domestic and foreign tax authorities. These audits may include questions regarding our tax filing positions, including the timing and amount of deductions and the allocation of income among various tax jurisdictions. At any one time, multiple tax years may be subject to audit by various tax authorities. In evaluating the exposures associated with our various tax filing positions, we record a liability for such exposures. A number of years may elapse before a particular matter for which we have established a liability is audited and fully resolved or clarified.

To the extent we prevail in matters for which a liability has been established, or are required to pay amounts in excess of our established liability, our effective income tax rate in a given financial statement period could be materially affected. An unfavorable tax settlement would generally require use of our cash and may result in an increase in our effective income tax rate in the period of resolution. A favorable tax settlement would be recognized as a reduction in our effective income tax rate in the period of resolution.

We recognize the impact of an uncertain income tax position on income tax expense at the largest amount that is more-likely-than-not to be sustained.  An unrecognized tax benefit will not be recognized unless it has a greater than 50% likelihood of being sustained. We adjust our tax liability for unrecognized tax benefits in the period in which an uncertain tax position is effectively settled, the statute of limitations expires for the relevant taxing authority to examine the tax position, or when more information becomes available. We recognize interest and penalties related to income tax matters as part of our provision for income taxes.

Our liability for unrecognized tax benefits contains uncertainties because management is required to make assumptions and apply judgment to estimate the exposures associated with our various filing positions. Our effective income tax rate is also affected by changes in tax law, the level of earnings and the results of tax audits.

Our provision for income taxes does not include provisions for U.S. income taxes and foreign withholding taxes associated with the repatriation of undistributed earnings of certain foreign operations that we intend to reinvest indefinitely in the foreign operations. If these earnings were distributed to the U.S. in the form of dividends or otherwise, we would be subject to additional U.S. income taxes, subject to an adjustment for foreign tax credits, and foreign withholding taxes. Our current plans do not require repatriation of earnings from foreign operations to fund the U.S. operations because we generate sufficient domestic operating cash flow and have access to external funding under our line of credit. As a result, we do not expect a material impact on our business or financial flexibility with respect to undistributed earnings of our foreign operations.

Although we believe that our judgments and estimates are reasonable, actual results could differ and we may be exposed to losses or gains that could be material.

RECENT ACCOUNTING PRONOUNCEMENTS

Recently Issued Pronouncements

In April 2015,March 2016, the Financial Accounting Standards Board ("FASB") issued additional guidance regarding share-based compensation, which outlines new provisions intended to simplify various aspects related to accounting for share-based payments and their presentation in the financial statements. The guidance is effective our fiscal year ended March 31, 2018. Early adoption is permitted. We are currently evaluating the effect this new accounting guidance may have on our consolidated results of operations and cash flows.

In February 2016, the FASB issued additional guidance regarding both operating and financing leases, requiring lessees to recognize on their balance sheets “right-of-use assets” and corresponding lease liabilities, measured on a discounted basis over the lease term. Virtually all leases will be subject to this treatment except leases that meet the definition of a “short-term lease.” For expense recognition, the dual model requiring leases to be classified as either operating or finance leases has been retained from the prior standard. Operating leases will result in straight-line expense while finance leases will result in a front-loaded expense pattern. Classification will use criteria very similar to those applied in current lease accounting, but without explicit bright lines. Extensive additional quantitative and qualitative disclosures, including significant judgments made by management, will be required to provide greater insight into the extent of expense recognized and expected to be recognized. The new lease guidance will essentially eliminate off-balance sheet financing. The guidance is effective for our fiscal year ending March 31, 2020. The new standard must be adopted using a modified retrospective transition that provides for certain practical expedients and requires the new guidance to be applied at the beginning of the earliest comparative period presented. We are currently evaluating the effect this new accounting guidance may have on our consolidated results of operations, financial position, and cash flows.

In January 2016, the FASB issued additional guidance regarding the recognition and measurement of financial assets and liabilities. Changes to the current GAAP model primarily affect the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. In addition, the FASB clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. We are required to adopt the standard in the first quarter of our fiscal year ending March 31, 2019, but may elect to adopt earlier as permitted under the standard. We are currently evaluating what impact, if any, the adoption of this standard will have on our consolidated results of operations, financial position, and cash flows.

In July 2015, the FASB issued additional guidance regarding the subsequent measurement of inventory by requiring inventory to be measured at the lower of cost and net realizable value. We are required to adopt the standard in the first quarter of our fiscal year ending March 31, 2018, but may elect to adopt earlier as permitted under the standard. The adoption is not expected to have a material impact on our consolidated results of operations, financial position, or cash flows.

In April 2015, the FASB issued additional guidance regarding cloud computing arrangements. The guidance requires registrants to account for a cloud computing arrangement that includes a software license element consistent with the acquisition of other software licenses. Cloud computing arrangement without software licenses are to be accounted for as a service contract. This guidance is effective for fiscal years and interim periods beginning after December 15, 2015. We have elected to adopt the new standard beginning in the first quarter of our fiscal year 2016. The adoption is not expected to have a material impact on our results of operations, financial position, or cash flows.

In April 2015, the FASB issued additional guidance regarding the presentation of debt issuance costs. The guidance requires debt issuance costs to be presented in the balance sheet as a direct deduction from the associated debt liability. This guidance is effective for fiscal years and interim periods beginning after December 15, 2015. We have elected to adopt the new standard beginning in the first quarter of our fiscal year 2016. The adoption is not expected to have a material impact on ourconsolidated results of operations, financial position, or cash flows.

In May 2014, the FASB issued additional guidance regarding revenue from contracts with customers. While the standard supersedes existing revenue recognition guidance, it closely aligns with current GAAP. Under the new standard, revenue will be recognized at the time a good or service is transferred to a customer for the amount of consideration received for that specific good or service. Entities may use a full retrospective approach or report the cumulative effect as of the date of adoption. On April 1, 2015,In March 2016, the FASB proposed deferringissued additional guidance concerning "Principal versus Agent" considerations (reporting revenue gross versus net); in April 2016, the FASB issued additional guidance on identifying performance obligations and licensing; and in May 2016, the FASB issued additional guidance on collectibility, noncash consideration, presentation of sales tax, and transition. These updates are intended to improve the operability and understandability of the implementation guidance and have the same effective date by one yearand transition requirements as the greater "contracts with customers" standard. We are required to December 15, 2017 for annual reporting periods beginning after that date. The FASB also proposed permitting early adoption ofadopt the standard, but not beforeas amended, in the original effective datefirst quarter of December 15, 2016.our fiscal year ending March 31, 2018 although, under the standard, we may adopt as early as the first quarter of our fiscal year ending March 31, 2017.  Presently, we are not yet in a position to assess the application date. We are currently evaluating what impact, if any, the adoption of this standard will have on our consolidated results of operations, financial position, orand cash flows.



ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 
The following discusses our exposure to market risk related to changes in interest rates and foreign currency exchange rates.  This discussion contains forward-looking statements that are subject to risks and uncertainties.  Actual results could vary materially as a result of a number of factors, including those set forth in Item 1A, Risk Factors.
 
INTEREST RATE AND MARKET RISK
 
As of March 31, 20152016 and 20142015, we reported the following balances in cash and cash equivalents, short-term investments, and long-term investments:

 March 31, March 31,

Table of Contents

Our investment policy and strategy are focused on preservation of capital and supporting our liquidity requirements. Our exposure to market risk for changes in interest rates relates primarily to our investment portfolio. Our investment policy limits the amount of credit exposure to any one issuer and requires investments to be high credit quality, primarily rated A or A2 and above, with the objective of minimizing the potential risk of principal loss. All highly liquid investments with initial maturities of three months or less at the date of purchase are classified as cash equivalents. We classify our investments as either short-term or long-term based on each instrument's underlying effective maturity date. All short-term investments have effective maturities less than 12 months, while all long-term investments have effective maturities greater than 12 months or we do not currently have the ability to liquidate the investments. We may sell our investments prior to their stated maturities for strategic purposes, in anticipation of credit deterioration, or for duration management. No material realized or unrealized net gains or losses were recognized during the years ended March 31, 20152016 and 20142015.

Interest rates were relatively unchanged in the year ended March 31, 20152016 compared to the prior year. During the year ended March 31, 20152016, we generated approximately $1.4$1.8 million of interest income from our portfolio of cash equivalents and investments, compared to $1.5$1.4 million in fiscal year 20142015. During the years ended March 31, 20152016 and 2014,2015, we did not incur a significant amount of interest expense due to outstanding balances under our revolving line of credit. The 5.50% Senior Notes are at a fixed interest rate and we have not elected the fair value option for these instruments; accordingly we are not exposed to any economic interest rate risk related to this indebtedness; however, the fair value of this instrument fluctuates as market interest rates change. The increase in interest expense caused by a 10 basis point increase in the interest rates of our variable-rate revolving line of credit indebtedness would not be significant. A hypothetical 10 basis points increase or decrease in ouron market interest rates by 10 basis pointsrelated to our investment portfolio would have a minimalan immaterial impact on our interest income or expense.results of operations.

FOREIGN CURRENCY EXCHANGE RATE RISK

We are a net receiver of currencies other than the U.S. dollar ("USD").  Accordingly, changes in exchange rates, and in particular a strengthening of the U.S. dollar, could negatively affect our net revenues and gross margins as expressed in USD.U.S. dollars.  There is a risk that we will have to adjust local currency product pricing in foreign countries due to competitive pressures if there is significant sustained volatility in foreign currency exchange rates.

WeThe primary currency fluctuations to which we are exposed to currency fluctuations, primarily inare the Euro ("EUR"), British Pound Sterling ("GBP"), Australian Dollar ("AUD"), Canadian Dollar ("CAD"), Mexican Peso ("MXN"), and the Chinese Renminbi ("RMB"). We use a hedging strategy to diminish, and make more predictable, the effect of currency fluctuations. All of our hedging activities are entered into with large financial institutions, which we periodically evaluate for credit risks. We hedge our balance sheet exposure by hedging EUR, GBP, AUD, and AUDCAD denominated cash, accounts receivable, and accounts payable balances, and our economic exposure by hedging a portion of anticipated EUR and GBP denominated sales and our MXN denominated expenditures. We can provide no assurance that our strategy will be successful in the future and that exchange rate fluctuations will not materially adversely affect our business. We do not hold or issue derivative financial instruments for speculative trading purposes.


We experienced $5.4$2.3 million in net foreign currency losses in the year ended March 31, 2015.2016. Although we hedge a portion of our foreign currency exchange exposure, the weakening of certain foreign currencies, particularly the EUR and GBP in comparison to the USD, could result in material foreign exchange losses in future periods.

Non-designated Hedges

We hedge our EUR, GBP, AUD, and AUDCAD denominated cash, accounts receivable, and accounts payable balances by entering into foreign exchange forward contracts.

The table below presents the impact on the foreign exchange gain (loss) of a hypothetical 10% appreciation and a 10% depreciation of the USD against the forward currency contracts as of March 31, 20152016 (in millions):

ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Plantronics, Inc.:

In our opinion, the consolidated financial statements listed in the index appearing under Item 15(a)(1) present fairly, in all material respects, the financial position of Plantronics, Inc. and its subsidiaries at March 28, 2015April 2, 2016 and March 29, 2014,28, 2015, and the results of their operations and their cash flows for each of the three years in the period ended March 28, 2015April 2, 2016 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedules listed in the index appearing under Item 15(a)(2) present fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of March 28, 2015,April 2, 2016, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for these financial statements and financial statement schedules, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on these financial statements, on the financial statement schedules, and on the Company's internal control over financial reporting based on our integrated 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 audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included 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, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

As discussed in Note 16 "Income Taxes" to the consolidated financial statements, the Company changed the manner in which it has classified deferred taxes on its consolidated balance sheet in 2016.

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

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

PLANTRONICS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.THE COMPANY
 
Plantronics, Inc. (“Plantronics” or “the Company”) is a leading worldwide designer, manufacturer, and marketer of lightweight communications headsets, telephone headset systems, and accessories for the business and consumer markets under the Plantronics brand. In addition, the Company manufactures and markets specialty products under its Clarity brand, such as telephones for the hearing impaired, and other related products for people with special communication needs. The Company operates its business as one segment.
 
Founded in 1961, Plantronics is incorporated in the state of Delaware and trades on the New York Stock Exchange under the ticker symbol “PLT”.

2.SIGNIFICANT ACCOUNTING POLICIES

Management's Use of Estimates and Assumptions
 
The Company's consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP"). In connection with the preparation of our financial statements, the Company is required to make assumptions and estimates about future events, and apply judgments that affect the reported amounts of assets, liabilities, net revenues, expenses, and the related disclosures. The Company bases its assumptions, estimates, and judgments on historical experience, current trends, future expectations, and other factors that management believes to be relevant at the time the consolidated financial statements are prepared. On an ongoing basis, the Company reviews its accounting policies, assumptions, estimates, and judgments, including those related to revenue and related reserves and allowances, inventory valuation, product warranty obligations, the useful lives of long-lived assets including property, plant and equipment and intangible assets, investment fair values, stock-based compensation, goodwill, income taxes, contingencies, and restructuring charges, to ensure that the consolidated financial statements are presented fairly and in accordance with U.S. GAAP. Because future events and their effects cannot be determined with certainty, actual results could differ from the Company's assumptions and estimates.

Principles of Consolidation
 
The consolidated financial statements include the accounts of Plantronics and its wholly owned subsidiaries.  The Company has included the results of operations of acquired companies from the date of acquisition. All intercompany balances and transactions have been eliminated.

Fiscal Year
 
The Company’s fiscal year ends on the Saturday closest to the last day of March. Fiscal years 2015, 2014, and 2013 each consisted of 52year 2016 had 53 weeks and ended on April 2, 2016, fiscal years 2015 and 2014 each had 52 weeks and ended on March 28, 2015,, and March 29, 2014,, and March 30, 2013, respectively.  For purposes of presentation, the Company has indicated its accounting fiscal year as ending on March 31.

Financial Instruments
 
Cash, Cash Equivalents and Investments
All highly liquid investments with initial stated maturities of three months or less at the date of purchase are classified as cash equivalents. The Company classifies its investments as either short-term or long-term based on each instrument's underlying effective maturity date and reasonable expectations with regard to sales and redemptions of the instruments. All short-term investments have effective maturities less than 12 months, while all long-term investments have effective maturities greater than 12 months. The Company may sell its investments prior to their stated maturities for strategic purposes, in anticipation of credit deterioration, or for duration management.   

As of March 31, 2015,2016, with the exception of assets related to the Company's deferred compensation plan, all investments were classified as available-for-sale, with unrealized gains and losses recorded as a separate component of accumulated other comprehensive income ("AOCI") in stockholders’ equity.  The specific identification method is used to determine the cost of disposed securities, with realized gains and losses reflected in interestother non-operating income and other income,(expense), net.


46


For investments with an unrealized loss, the factors considered in the review include the credit quality of the issuer, the duration that the fair value has been less than the adjusted cost basis, severity of impairment, reason for the decline in value and potential recovery period, the financial condition and near-term prospects of the investees, and whether the Company would be required to sell an investment due to liquidity or contractual reasons before its anticipated recovery.

Foreign Currency Derivatives
The Company accounts for its derivative instruments as either assets or liabilities and carries them at fair value.  Derivative foreign currency contracts are valued using pricing models that use observable inputs. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and the resulting designation.  

The Company enters into foreign exchange forward contracts to reduce the impact of foreign currency fluctuations on assets and liabilities denominated in currencies other than the functional currency of the reporting entity.  The Company does not elect to obtain hedge accounting for these forward contracts. These forward contracts are carried at fair value with changes in the fair value recorded within interestother non-operating income and other income (expense), net in the consolidated statements of operations.  Gains and losses on these contracts are intended to offset the impact of foreign exchange rate changes on the underlying foreign currency denominated assets and liabilities, and therefore, do not subject the Company to material balance sheet risk. 

The Company has significant international revenues and costs denominated in foreign currencies, subjecting it to foreign currency risk. The Company purchases foreign currency option contracts and cross-currency swaps that qualify as cash flow hedges, with maturities of 12up to 24 months, or less, to reduce the volatility of cash flows related primarily to forecasted revenue and intercompany transactions denominated in certain foreign currencies. All outstanding derivatives are recognized on the balance sheet at fair value. The effective portion of the designated derivative's gain or loss is initially reported as a component of AOCI and is subsequently reclassified into the financial statement line item in which the hedged item is recorded in the same period the forecasted transaction affects earnings.
 
The Company does not hold or issue derivative financial instruments for speculative trading purposes.  Plantronics enters into derivatives only with counterparties that are among the largest United States ("U.S.") banks, ranked by assets, in order to minimize its credit risk and to date, no such counterparty has failed to meet its financial obligations under such contracts. 

Provision for Doubtful Accounts
 
The Company maintains a provision for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments.  Plantronics regularly performs credit evaluations of its customers’ financial conditions and considers factors such as historical experience, credit quality, age of the accounts receivable balances, geographic or country-specific risks, and economic conditions that may affect a customer’s ability to pay.  

Inventory and Related Reserves
 
Inventories are valued at the lower of cost or market.  Cost is computed using standard cost, which approximates actual cost on a first-in, first-out basis. The Company writes down inventories that have become obsolete or are in excess of anticipated demand or net realizable value. Our estimate of write downs for excess and obsolete inventory is based on a detailed analysis of on-hand inventory and purchase commitments in excess of forecasted demand. 

A substantial portion of the raw materials, components and subassemblies (together, “parts”) used in the Company's products are provided by its suppliers on a consignment basis. These consigned inventories are not recorded on the Company's consolidated balance sheet until it takes title to the parts, which occurs when they are consumed in the production process. The Company provides forecasts to its suppliers covering up to thirteen weeks of demand and places purchase orders when the parts are consumed in the production process, at which time all right, title, and interest in and to the parts transfers to the Company. Prior to consumption in the production process, the Company's suppliers bear the risk of loss and retain title to the consigned inventory.

The terms of the agreements allow the Company to return parts in excess of maximum order quantities to the suppliers at the supplier’s expense. Returns for other reasons are negotiated with the suppliers on a case-by-case basis and to date have been immaterial. As of March 31, 2015,2016, the Company’s aggregate commitment to suppliers for parts used in the manufacture of the Company’s products was $123.0150.9 million, which the Company expects to utilize in the normal course of business, net of an immaterial purchase commitments reserve. The Company’s purchase commitments reserve reflects the Company’s estimate of purchase commitments it does not expect to use in normal ongoing operations within the next twelve months. As of March 31, 20152016 and 2014,2015, the off-balance sheet consigned inventory balances were $33.4$41.1 million and $40.0$33.4 million, respectively.

Product Warranty Obligations
 
The Company records a liability for the estimated costs of warranties at the time the related revenue is recognized. The specific warranty terms and conditions range from one to two years starting from the delivery date to the end user and vary depending upon the product sold and the country in which the Company does business. Factors that affect the warranty obligations include product failure rates, estimated return rates, the amount of time lapsed from the date of sale to the date of return, material usage, service related costs incurred in correcting product failure claims, and knowledge of specific product failures that are outside of the Company’s typical experience.

Goodwill and Purchased Intangibles
 
Goodwill has been measured as the excess of the cost of acquisition over the amount assigned to tangible and identifiable intangible assets acquired less liabilities assumed.  At least annually, in the fourth quarter of each fiscal year or more frequently if indicators of impairment exist, management performs a review to determine if the carrying value of goodwill is impaired. The identification and measurement of goodwill impairment involves the estimation of fair value at the Company’s reporting unit level.  The Company determines its reporting units by assessing whether discrete financial information is available and if segment management regularly reviews the results of that component. The Company has determined it has one reporting unit.

The Company performs an initial assessment of qualitative factors to determine whether the existence of events and circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of relevant events and circumstances, the Company determines that it is more likely than not that the fair value of the reporting unit exceeds its carrying value and there is no indication of impairment, no further testing is performed; however, if the Company concludes otherwise, the first step of the two-step impairment test must be performed by estimating the fair value of the reporting unit and comparing it with its carrying value, including goodwill.

Intangible assets other than goodwill are carried at cost and amortized over their estimated useful lives. The Company reviews identifiable finite-lived intangible assets to be held and used for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. Determination of recoverability is based on the lowest level of identifiable estimated undiscounted cash flows resulting from use of the asset and its ultimate disposition. Measurement of any impairment loss is based on the amount by which the carrying value of the asset exceeds its fair market value.

Property, Plant and Equipment
 
Property, plant and equipment is stated at cost less accumulated depreciation and amortization. Depreciation is calculated using the straight-line method over the estimated useful lives of the respective assets, which range from two to thirty years.  Amortization of leasehold improvements is computed using the straight-line method over the shorter of the estimated useful lives of the assets or the remaining lease term. Capitalized software costs are amortized on a straight-line basis over the estimated useful life of the assets.
 
Property, plant and equipment is reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The Company recognizes an impairment charge in the event the net book value of such assets exceeds the future undiscounted cash flows attributable to the asset group. No material impairment losses were incurred in the periods presented.

Fair Value Measurements

All financial assets and liabilities and non-financial assets and liabilities are recognized or disclosed at fair value in the financial statements. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:

Level 1
The Company's Level 1 financial assets consist of mutual funds.Mutual Funds and US Treasury Notes. The fair value of Level 1 financial instruments is measured based on the quoted market price of identical securities.


Level 2
The Company's Level 2 financial assets and liabilities consist of Mutual Funds, Government Agency Securities, Commercial Paper, Corporate Bonds, and Corporate Bonds.Certificates of Deposits ("CDs").


48


The fair value of Level 2 investment securities is determined based on other observable inputs, including multiple non-binding quotes from independent pricing services. Non-binding quotes are based on proprietary valuation models that are prepared by the independent pricing services and use algorithms based on inputs such as observable market data, quoted market prices for similar securities, issuer spreads, and internal assumptions of the broker. The Company corroborates the reasonableness of non-binding quotes received from the independent pricing services using a variety of techniques depending on the underlying instrument, including: (i) comparing them to actual experience gained from the purchases and maturities of investment securities, (ii) comparing them to internally developed cash flow models based on observable inputs, and (iii) monitoring changes in ratings of similar securities and the related impact on fair value.

The fair value of Level 2 derivative foreign currency contracts is determined using pricing models that use observable market inputs. The fair value of Level 2 long-term debt is determined based on inputs that were observable in the market, including the trading price of the notes when available.

Level 3
The Company's unsecured revolving credit facility falls under the Level 3 hierarchy. The fair value of the Company’s line of credit approximates its carrying value because the interest rate is a variable rate that approximates rates currently available to the Company. 

Revenue Recognition
 
The Company sells substantially all of its products to end users through distributors, retailers, and carriers. The Company's revenue is derived from the sale of headsets, telephone headset systems, and accessories for the business and consumer markets and is recognized when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the sales price is fixed or determinable, and collection is reasonably assured. These criteria are usually met at the time of product shipment; however, the Company defers revenue when any significant obligations remain and to date this has accounted for less than 1% of the Company's net revenues. Customer purchase orders and/or contracts are used to determine the existence of an arrangement. Product is considered delivered once it has been shipped and title and risk of loss have been transferred to the customer. The Company assesses whether a price is fixed or determinable based upon the selling terms associated with the transaction and whether the sales price is subject to refund or adjustment. The Company assesses collectibilitycollectability based on a customer's credit quality, historical experience, and geographic or country-specific risks and economic conditions that may affect a customer's ability to pay.

Revenue is recorded net of taxes collected from customers that are remitted to governmental authorities, with the collected taxes recorded as current liabilities until remitted to the relevant government authority. Shipping and handling costs incurred in connection with the sale of products are included in cost of revenues.

Sales through retail and distribution channels are made primarily under agreements or commitments allowing for rights of return and include various sales incentive programs, such as rebates, advertising, price protection, and other sales incentives. The Company has an established sales history for these arrangements and records the estimated reserves and allowances at the time the related revenue is recognized. Sales return reserves are estimated based on historical data, relevant current data, and the monitoring of inventory build-up in the distribution channel. The allowance for sales incentive programs is based on contractual terms or commitments and historical experience in the form of lump sum payments or sell-through credits.

When a sales arrangement contains multiple elements, such as hardware and software products and/or services, the Company allocates revenue to each element based on relative selling prices. The selling price for a deliverable is based on its vendor specific objective evidence ("VSOE"), if available, third party evidence ("TPE") if VSOE is not available, or estimated selling price ("ESP") if neither VSOE nor TPE is available. In multiple element arrangements where more-than-incidental software deliverables are included, the Company allocates revenue to each separate unit of accounting for each of the non-software deliverables and to the software deliverables as a group using the relative selling prices of each of the deliverables in the arrangement based on the aforementioned selling price hierarchy.

Advertising Costs
 
The Company expenses all advertising costs as incurred.  Advertising expense for the years ended March 31, 20152016, 2015, and 2014 was 2014$2.0 million, and 2013 was $3.7 million, and $4.0 million, and $3.6 million, respectively.


Income Taxes

Deferred income taxes are determined based on the differences between the financial reporting and tax bases of assets and liabilities and are measured using the currently enacted tax rates and laws. The Company records a valuation allowance against particular deferred income tax assets if it is more likely than not that those assets will not be realized. The provision for income taxes comprises the Company's current tax liability and changes in deferred income tax assets and liabilities.


49


Significant judgment is required in evaluating the Company's uncertain tax positions and determining its provision for income taxes. The Company establishes reserves for tax-related uncertainties based on estimates of whether, and the extent to which, additional taxes will be due. These reserves are established when the Company believes that certain positions might be challenged despite its belief that its tax return positions are in accordance with applicable tax laws. The Company adjusts these reserves in light of changing facts and circumstances, such as the closing of a tax audit, new tax legislation, or the change of an estimate. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will affect the provision for income taxes in the period in which such determination is made. The provision for income taxes includes the effect of reserve provisions and changes to reserves that are considered appropriate, as well as the related net interest and penalties.

The Company follows the tax law ordering to determine when excess tax benefits have been realized.

The Company is subject to income taxes in the U.S. and foreign jurisdictions. At any one time, multiple tax years are subject to audit by various tax authorities.

Earnings Per Share
 
Basic earnings per share is computed by dividing the net income for the period by the weighted average number of common shares outstanding during the period, less common stock subject to repurchase.  Diluted earnings per share is computed by dividing the net income for the period by the weighted average number of shares of common stock and potentially dilutive common stock outstanding during the period.  Potentially dilutive common shares include shares issuable upon the exercise of outstanding stock options, the vesting of awards of restricted stock, and the estimated shares to be purchased under the Company’s employee stock purchase plan ("ESPP"), which are reflected in diluted earnings per share by application of the treasury stock method.  Under the treasury stock method, the amount that the employee must pay for exercising stock options, the amount of stock-based compensation cost for future services that the Company has not yet recognized, and the amount of tax benefit that would be recorded in additional paid-in capital upon exercise are assumed to be used to repurchase shares.  
 
Comprehensive Income
 
Comprehensive income consists of two components, net income and other comprehensive income.  Other comprehensive income refers to income, expenses, gains, and losses that under U.S. GAAP are recorded as an element of stockholders’ equity but are excluded from net income.  Accumulated other comprehensive income, as presented in the accompanying consolidated balance sheets, consists of foreign currency translation adjustments, unrealized gains and losses on derivatives designated as cash flow hedges, net of tax, and unrealized gains and losses on marketable securities classified as available-for-sale, net of tax.
 
Foreign Operations and Currency Translation

The functional currency of the Company’s foreign sales and marketing offices, except as noted in the following paragraph, is the local currency of the respective operations.  For these foreign operations, the Company translates assets and liabilities into U.S. dollars using the period-end exchange rates in effect as of the balance sheet date and translates revenues and expenses using the average monthly exchange rates.  The resulting cumulative translation adjustments are included in accumulated other comprehensive income, a separate component of stockholders' equity on the accompanying consolidated balance sheets.

The functional currency of the Company’s European finance, sales and logistics headquarters in the Netherlands, sales office and warehouse in Japan, a manufacturing facility in Tijuana, Mexico, and logistic and research and development facilities in China, is the U.S. Dollar.  For these foreign operations, assets and liabilities denominated in foreign currencies are re-measured at the period-end or historical rates, as appropriate.  Revenues and expenses are re-measured at average monthly rates, which the Company believes to be a fair approximation of actual rates.  Currency transaction gains and losses are recognized in current operations.
 

Stock-Based Compensation Expense

The Company applies the provisions of the Compensation - Stock Compensation Topic of the FASB ASC, which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and non-employee directors based on estimated fair values. The Company recognizes the grant-date fair value of stock-based compensation as compensation expense using the straight-line attribution approach over the service period for which the stock-based compensation is expected to vest.


50


The Company usesfollows the “with and without”tax law ordering approach in determining the order in whichto determine when excess tax attributes are utilized. As a result, the Company only recognizes a tax benefitbenefits from stock-based awards have been realized and are recognized in additional paid-in capital if an incremental tax benefit is realized after all other tax attributes currently available to the Company have been utilized.capital. When tax deductions from stock-based awards are less than the cumulative book compensation expense, the tax effect of the resulting difference (“shortfall”) is charged first to additional paid-in capital to the extent of the Company's pool of windfall tax benefits, with any remainder recognized in income tax expense. The Company has determined that it had a sufficient windfall pool available through the end of fiscal year 20152016 to absorb any shortfalls. In addition, the Company accounts for the indirect effects of stock-based awards on other tax attributes, such as the research tax credit, through the consolidated statements of operations.

Treasury Shares
 
From time to time, the Company repurchases shares of its common stock, depending on market conditions, in the open market or through privately negotiated transactions, in accordance with programs authorized by the Board of Directors.  Repurchased shares are held as treasury stock until such time as they are retired or re-issued. Retirements of treasury stock are non-cash equity transactions in which the reacquired shares are returned to the status of authorized but unissued shares and the cost is recorded as a reduction to both retained earnings and treasury stock. The stock repurchase programs are intended to offset the impact of dilution resulting from the Company's stock-based compensation programs.

Concentration of Risk
 
Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash equivalents, short-term and long-term investments, and trade accounts receivable.  

Plantronics’ investment policy limits investments to highly-rated securities. In addition, the Company limits the amount of credit exposure to any one issuer and restricts placement of these investments to issuers evaluated as creditworthy.  As of March 31, 2016 the Company's investments were composed of Mutual Funds, US Treasury Notes, Government Agency Securities, Commercial Paper, Corporate Bonds, and Certificates of Deposits ("CDs"). As of March 31, 2015, the Company's investments were composed of Mutual Funds, Government Agency Securities, Commercial Paper, and Corporate Bonds. As of March 31, 2014, the Company's investments were composed of Mutual Funds, Government Agency Securities, Commercial Paper, Corporate Bonds, and CDs.

Concentrations of credit risk with respect to trade receivables are limited due to the large number of customers that comprise the Company’s customer base and their dispersion across different geographies and markets. One customer, SYNNEX Corporation, accounted for 11.2% of total net accounts receivable as of March 31, 2016. One customer D&H Distributing accounted for 11.1% of total net accounts receivable as of March 31, 2015. No customer accounted for 10% or more of total net accounts receivable as of March 31, 2014. The Company does not believe other significant concentrations of credit risk exist. Plantronics performs ongoing credit evaluations of its customers' financial condition and requires no collateral from its customers.  The Company maintains a provision for doubtful accounts based upon expected collectibility of all accounts receivable.

Certain inventory components required by the Company are only available from a limited number of suppliers.  The rapid rate of technological change and the necessity of developing and manufacturing products with short lifecycles may intensify these risks.  The inability to obtain components as required, or to develop alternative sources, as required in the future, could result in delays or reductions in product shipments, which in turn could have a material adverse effect on the Company’s business, financial condition, results of operations and cash flows. 

3.RECENT ACCOUNTING PRONOUNCEMENTS

Recently Issued Pronouncements

In April 2015,March 2016, the Financial Accounting Standards Board ("FASB") issued additional guidance regarding share-based compensation, which outlines new provisions intended to simplify various aspects related to accounting for share-based payments and their presentation in the financial statements. The guidance is effective for the Company's fiscal year ended March 31, 2018. Early adoption is permitted. The Company currently evaluating the effect this new accounting guidance may have on its consolidated results of operations and cash flows.


In February 2016, the FASB issued additional guidance regarding both operating and financing leases, requiring lessees to recognize on their balance sheets “right-of-use assets” and corresponding lease liabilities, measured on a discounted basis over the lease term. Virtually all leases will be subject to this treatment except leases that meet the definition of a “short-term lease.” For expense recognition, the dual model requiring leases to be classified as either operating or finance leases has been retained from the prior standard. Operating leases will result in straight-line expense while finance leases will result in a front-loaded expense pattern. Classification will use criteria very similar to those applied in current lease accounting, but without explicit bright lines. Extensive additional quantitative and qualitative disclosures, including significant judgments made by management, will be required to provide greater insight into the extent of expense recognized and expected to be recognized. The new lease guidance will essentially eliminate off-balance sheet financing. The guidance is effective for the Company's fiscal year ending March 31, 2020. The new standard must be adopted using a modified retrospective transition that provides for certain practical expedients and requires the new guidance to be applied at the beginning of the earliest comparative period presented. The Company is currently evaluating the effect this new accounting guidance may have on its consolidated results of operations, cash flows, and financial position.

In January 2016, the FASB issued additional guidance regarding the recognition and measurement of financial assets and liabilities. Changes to the current GAAP model primarily affect the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. In addition, the FASB clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The Company is required to adopt the standard in the first quarter of its fiscal year ending March 31, 2019, but may elect to adopt earlier as permitted under the standard. The Company is currently evaluating what impact, if any, the adoption of this standard will have on its consolidated results of operations, financial position, and cash flows.

In July 2015, the FASB issued additional guidance regarding the subsequent measurement of inventory by requiring inventory to be measured at the lower of cost and net realizable value. The Company is required to adopt the standard in the first quarter of its fiscal year ending March 31, 2018, but may elect to adopt earlier as permitted under the standard. The adoption is not expected to have a material impact on the Company's results of operations, financial position, or cash flows.

In April 2015, the FASB issued additional guidance regarding cloud computing arrangements. The guidance requires registrants to account for a cloud computing arrangement that includes a software license element consistent with the acquisition of other software licenses. Cloud computing arrangement without software licenses are to be accounted for as a service contract. This guidance is effective for fiscal years and interim periods beginning after December 15, 2015. The Company has elected to adopt the new standard beginning in the first quarter of its fiscal year 2016. The adoption is not expected to have a material impact on the Company's consolidated results of operations, financial position, or cash flows.

In April 2015, the FASB issued additional guidance regarding the presentation of debt issuance costs. The guidance requires debt issuance costs to be presented in the balance sheet as a direct deduction from the associated debt liability. This guidance is effective for fiscal years and interim periods beginning after December 15, 2015. The Company has elected to adopt the new standard beginning in the first quarter of its fiscal year 2016. The adoption is not expected to have a material impact on the Company's results of operations, financial position, or cash flows.



51


In May 2014, the FASB issued additional guidance regarding revenue from contracts with customers. While the standard supersedes existing revenue recognition guidance, it closely aligns with current GAAP. Under the new standard, revenue will be recognized at the time a good or service is transferred to a customer for the amount of consideration received for that specific good or service. Entities may use a full retrospective approach or report the cumulative effect as of the date of adoption. On April 1, 2015,In March 2016, the FASB proposed deferringissued additional guidance concerning "Principal versus Agent" considerations (reporting revenue gross versus net); in April 2016, the FASB issued additional guidance on identifying performance obligations and licensing; and in May 2016, the FASB issued additional guidance on collectibility, noncash consideration, presentation of sales tax, and transition. These updates are intended to improve the operability and understandability of the implementation guidance and have the same effective date by one yearand transition requirements as the greater "contracts with customers" standard. The Company is required to December 15, 2017 for annual reporting periods beginning after that date. The FASB also proposed permitting early adoption ofadopt the standard, but not beforeas amended, in the original effective datefirst quarter of December 15, 2016.its fiscal year ending March 31, 2018 although, under the standard, it may adopt as early as the first quarter of its fiscal year ending March 31, 2017.  Presently, the Company is not yet in a position to assess the application date. The Company is currently evaluating what impact, if any, the adoption of this standard will have on its consolidated results of operations, financial position, orand cash flows.

As of March 31, 20152016 and 2014,2015, with the exception of assets related to the Company's deferred compensation plan, all of the Company's investments are classified as available-for-sale securities. The carrying value of available-for-sale securities included in cash equivalents approximates fair value because of the short maturity of those instruments.

52


The Company did not incur any material realized or unrealized net gains or losses for the fiscal years ended March 31, 20152016 and 20142015.

There were no transfers between fair value measurement levels during the years ended March 31, 20152016 and 20142015.



5.     DEFERRED COMPENSATION

As of March 31, 2015,2016, the Company held investments in mutual funds totaling $5.5$9.5 million, all of which related to debt and equity securities that are held in a rabbi trust under non-qualified deferred compensation plans. The total related deferred compensation liability was $5.5$9.5 million at March 31, 2015.2016. The fair value of debt and equity securities held in the rabbi trust at March 31, 20142015 was $1.8$5.5 million. The total related deferred compensation liability at March 31, 20142015 was $1.8$5.5 million.

The securities are classified as trading securities and are recorded on the Consolidated Balance Sheets under "Short-term investments". The liability is recorded on the Consolidated Balance Sheets under “Other long-term liabilities”.

Goodwill as of
March 31, 20152016 and March 31, 20142015 was $15.5 million and $15.5 million, net of accumulated impairment of $54.6 million. In fiscal years 20152016 and 2014,2015, for purposes of the annual goodwill impairment test, the Company determined there to be no reporting units below its operating segment; therefore, the annual goodwill impairment analysis was performed at the segment level in both of these years. In the fourth quarter of fiscal years 20152016 and 2014,2015, the Company evaluated qualitative factors that may affect the fair value of the reporting unit and concluded there to be no indication of goodwill impairment.

Unconditional Purchase Obligations

The Company purchases services and components from a variety of suppliers and manufacturers. During the normal course of business and to manage manufacturing operations and general and administrative activities, the Company may enter into firm, non-cancelable, and unconditional purchase obligations for which amounts are not recorded on the consolidated balance sheets. Such obligations totaled $123.0150.9 million as of March 31, 20152016.

Other Guarantees and Obligations

In the ordinary course of business, the Company may provide indemnifications of varying scope and terms to customers, vendors, lessors, business partners, purchasers of assets or subsidiaries and other parties with respect to certain matters, including, but not limited to, losses arising out of the Company's breach of agreements or representations and warranties made by the Company, services to be provided by the Company, intellectual property infringement claims made by third parties or, with respect to the sale of assets or a subsidiary, matters related to the Company's conduct of the business and tax matters prior to the sale. From time to time, the Company indemnifies customers against combinations of loss, expense, or liability arising from various triggering events relating to the sale and use of its products and services.  In addition, Plantronics also provides protection to customers against claims related to undiscovered liabilities, additional product liability, or environmental obligations.  In addition, the Company has entered into indemnification agreements with its directors and certain of its officers that will require the Company, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers. The Company maintains director and officer insurance, which may cover certain liabilities arising from its obligation to indemnify its directors and officers in certain circumstances. It is not possible to determine the aggregate maximum potential loss under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Such indemnification agreements might not be subject to maximum loss clauses. Historically, the Company has not incurred material costs as a result of obligations under these agreements and it has not accrued any liabilities related to such indemnification obligations in the consolidated financial statements.

Claims and Litigation

On October 12, 2012, GN Netcom, Inc. ("GN") sued Plantronics, Inc. in the United States ("U.S.") District Court for the District of Delaware, alleging violations of the Sherman Act, the Clayton Act, and Delaware common law. In its complaint, GN specifically alleges four causes of action: Monopolization, Attempted Monopolization, Concerted Actionmonopolization, attempted monopolization, concerted action in Restraintrestraint of Trade,trade, and Tortious Interferencetortious interference with Business Relations.business relations. GN claims that Plantronicsthe Company dominates the market for headsets sold into contact centers in the United StatesU.S. and that a critical channel for sales of headsets to contact centers is through a limited network of specialized independent distributors (“SIDs”). GN asserts that Plantronicsthe Company attracts SIDs through Plantronics Only Distributor Agreementsexclusive distributor agreements and alleges that the use of these agreements is allegedly illegal. The Company denies each of the allegations in the complaint and is vigorously defending itself. Given the preliminary nature of the case, the Company is unable to estimate an amount or range of any reasonably possible losses resulting from these allegations.

During the quarter ended December 26, 2015, GN Netcom (“GN”) and the Company commenced the briefing on a motion for sanctions against Plantronics for spoliation of evidence. The briefing was concluded in early January. A court date for a hearing on the motion for sanctions is scheduled for May 18, 2016. There exists a reasonable possibility of the court issuing a sanction; however, the Company believes the low end of the possible range of losses is zero and the upper end of the range is immaterial. In the event the Company were to incur other, non-monetary sanctions for spoliation of evidence, it may have an adverse impact on the substantive case brought against the Company on October 12, 2012. However, the Company is unable to estimate a loss or range of losses that could possibly result from the substantive case should non-monetary sanctions be brought against the Company.
In addition to the specific matters discussed above, the Company is involved in various legal proceedings arising in the normal course of conducting business. For such legal proceedings, where applicable, the Company has accrued an amount that reflects the aggregate liability deemed probable and estimable, but this amount is not material to the Company's financial condition, results of operations, or cash flows. TheWith respect to proceedings for which no accrual has been made, the Company is not able to estimate an amount or range of any reasonably possible additional losses because of the preliminary nature of many of these proceedings, the difficulty in ascertaining the applicable facts relating to many of these proceedings, the variable treatment of claims made in many of these proceedings, and the difficulty of predicting the settlement value of many of these proceedings; however,proceedings. However, based upon the Company's historical experience, the resolution of these proceedings is not expected to have a material effect on the Company's financial condition, results of operations or cash flows. The Company may incur substantial legal fees, which are expensed as incurred, in defending against these legal proceedings.

9. CREDIT AGREEMENT


9. Debt

5.50% Notes

In May 2015, Plantronics issued $500.0 million aggregate principal amount of 5.50% senior notes (the “5.50% Senior Notes”). The 5.50% Senior Notes mature on May 31, 2023, and bear interest at a rate of 5.50% per annum, payable semi-annually on May 15 and November 15 of each year, commencing on November 15, 2015. The Company received net proceeds of $488.4 million from issuance of the 5.50% Senior Notes, net of issuance costs of $11.6 million which are being amortized to interest expense over the term of the 5.50% Senior Notes using the effective interest method.

Effective for the first quarter of fiscal year 2016, the Company early adopted the update to balance sheet classification of debt issuance costs (Accounting Standards Update 2015-03), which simplifies the presentation of debt issuance costs by requiring them to be classified as reduction of the carrying value of the debt on the balance sheets. As such, the Company has presented the carrying value of the 5.50% Senior Notes net of such costs within the long-term liability section within the consolidated balance sheets as of March 31, 2016. There was no impact on the Company's results of operations as a result of the adoption of this standard.

The fair value of the 5.50% Senior Notes was determined based on inputs that were observable in the market, including the trading price of the 5.50% Senior Notes when available (Level 2). The estimated fair value and carrying value of the 5.50% Senior Notes were as follows:

(in thousands)Fair Value Carrying Value Fair Value Carrying Value
5.50% Senior Notes$

 $493,440
 $489,609

The Company may redeem all or a part of the 5.50% Senior Notes, upon not less than 30 or more than a 60 day notice; however, the applicable redemption price will be determined as follows:
Redemption Period Requiring Payment of:
Redemption Up To 35% Using Cash Proceeds From An Equity Offering(3):

DateSpecified Price
5.50% Senior NotesPrior to May 15, 2018On or after May 15, 2018Prior to May 15, 2018105.50%
(1) If the Company redeems the notes prior to the applicable date, the price is principal plus a make-whole premium equal to the present value of the remaining scheduled interest payments as described in the applicable indenture, together with accrued and unpaid interest.
(2) If the Company redeems the notes on or after the applicable date, the price is principal plus a premium which declines over time as specified in the applicable indenture, together with accrued and unpaid interest.
(3) If the Company redeems the notes prior to the applicable date with net cash proceeds of one or more equity offerings, the price is equal to the amount specified above, together with accrued and unpaid interest, subject to a maximum redemption of 35% of the aggregate principal amount of the respective note being redeemed.

In addition, upon the occurrence of certain change of control triggering events, the Company may be required to repurchase the 5.50% Senior Notes, at a price equal to 101% of their principal amount, plus accrued and unpaid interest to the date of repurchase. The 5.50% Senior Notes contain restrictive covenants that, among other things, limit Plantronics' ability to create certain liens and enter into sale and leaseback transactions; create, assume, incur, or guarantee additional indebtedness of Plantronics’ subsidiaries without such subsidiary guaranteeing the 5.50% Senior Notes on an unsecured unsubordinated basis; and consolidate or merge with, or convey, transfer or lease all or substantially all of the assets of Plantronics and its subsidiaries to another person. As of March 31, 2016, the Company was in compliance with all covenants.

Pursuant to the terms of the waiver and amendment to the Credit Agreement, the $16.2 million of restructuring charges recorded in the Company's fiscal year 2016 will be excluded from the lender’s rolling four-quarter EBITDA calculation.  This exclusion of restructuring charges does not automatically extend to any such future charges, should they be incurred.

This breach is not considered to be a cross-default on the Company's 5.50% Senior Notes and as such has no impact on the amount or timing of amounts payable related to these debt instruments.

10.STOCK PLANS AND STOCK-BASED COMPENSATION

2003 Stock Plan
 
On May 5, 2003, the Board of Directors ("Board") adopted the Plantronics, Inc. 2003 Stock Plan ("2003 Stock Plan") which was approved by the stockholders in June 27, 2003.

The weighted average grant-date fair value of restricted stock is based on the quoted market price of the Company's common stock on the date of grant. The weighted average grant-date fair values of restricted stock granted during fiscal years 20152016, 20142015 and 20132014 were $54.66, $45.28, $46.0245.26, and $32.2246.02, respectively. The total grant-date fair values of restricted stock that vested during fiscal years 20152016, 20142015, and 20132014 were $24.2 million, $17.6 million, $12.8 million, and $7.912.8 million, respectively.

As of March 31, 20152016, the total unrecognized compensation cost related to non-vested restricted stock awards was $32.8$31.4 million and is expected to be recognized over a weighted average period of 1.71.5 years.

Valuation Assumptions
 
The Company estimates the fair value of stock options and ESPP shares using a Black-Scholes option valuation model.  At the date of grant, the Company estimated the fair value of each stock option grant and purchase right granted under the ESPP using the following weighted average assumptions:
 Employee Stock Options ESPP Employee Stock Options ESPP

The expected stock price volatility for the years ended March 31, 20152016, 2014,2015, and 20132014 was determined based on an equally weighted average of historical and implied volatility.  Implied volatility is based on the volatility of the Company’s publicly traded options on its common stock with terms of six months or less.  The Company determined that a blend of implied volatility and historical volatility is more reflective of market conditions and a better indicator of expected volatility than using exclusively historical volatility.  The expected life was determined based on historical experience of similar awards, giving consideration to the contractual terms of the stock-based awards, vesting schedules, and expectations of future employee behavior.  The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option.  The dividend yield assumption is based on our current dividend and the market price of our common stock at the date of grant.

11. RESTRUCTURING AND OTHER RELATED CHARGES

The Company initiated a restructuring plan during the third quarter of fiscal year 2016. Under the plan, the Company reduced costs by eliminating approximately 125 positions in the U.S., Mexico, China, and Europe, substantially all of which took place in the fourth quarter of the Company's fiscal year 2016. These actions were designed to better align expenses to the Company’s revenue and gross margin profile and position the Company for improved operating performance.



The Company recorded pre-tax charges of approximately $16.2 million, consisting severance and related benefits. These charges were offset by a reduction in fiscal year 2016 stock-based compensation expense of $1.5 million attributable to stock award forfeitures resulting from the restructuring action. The restructuring plan was substantially complete by the end of the fourth quarter of fiscal year 2016.

The following table summarizes the Company's restructuring activities for the fiscal year 2016:
(in thousands) Severance and related benefits
Balance at March 31, 2015 $
Additions 14,275
Payments (10,385)
Adjustments 1,893

The activity in the table above excludes the impact of the stock award forfeitures which were recognized in the functional line items within the Company's condensed consolidated statement of operations in which they were originally recorded.

12. COMMON STOCK REPURCHASES

From time to time, the Board authorizes programs under which the Company may repurchase shares of its common stock, depending on market conditions, in the open market or through privately negotiated transactions. Repurchased shares are held as treasury stock until such time they are retired or re-issued. During the years ended March 31, 20152016, 2014,2015, and 2013,2014, the Company repurchased 9,077,223, 2,221,448, 1,949,407, and 751,7061,949,407 shares of its common stock, respectively, for a total cost of $112.9$497.4 million, $85.7$112.9 million, and $23.985.7 million, respectively, and at an average price per share of $54.80, $50.84, $43.94, and $31.8443.94, respectively.

Table of Contents

The Company financed the repurchases using a combination of funds generated from operations and borrowings under its revolving line of credit. All repurchases in fiscal years 2016, 2015, 2014, and 20132014 were made in the open market. As of March 31, 20152016, there remained 2,711,052634,011 shares authorized for repurchase under the program approved by the Board on March 4, 2015.January 29, 2016.

The Company withheld shares valued at $7.6$11.1 million during the year ended March 31, 20152016, compared to $6.27.6 million in fiscal year 2014,2015, and $3.0$6.2 million in fiscal year 2013,2014, in satisfaction of employee tax withholding obligations upon the vesting of restricted stock granted under the Company's stock plans. The amounts withheld were equivalent to the employees' minimum statutory tax withholding requirements and are reflected as a financing activity within the Company's consolidated statements of cash flows. These share withholdings have the effect of share repurchases by the Company because they reduce the number of shares outstanding as a result of the vesting.

There were no retirements of treasury stock during fiscal years 2016, 2015, and 2014. During the year ended March 31, 2013, the Company retired 5,398,376 shares of treasury stock at a total value of $176.3 million. These were non-cash equity transactions in which the cost of the reacquired shares was recorded as a reduction to both retained earnings and treasury stock. These shares were returned to the status of authorized but unissued shares.

13.14.EMPLOYEE BENEFIT PLANS

The Company has a defined contribution benefit plan under Section 401(k) of the Internal Revenue Code, which covers substantially all U.S. employees. Eligible employees may contribute pre-tax amounts to the plan through payroll withholdings, subject to certain limitations. Under the plan, the Company currently matches 50% of the first 6% of employees' compensation and provides a non-elective Company contribution equal to 3% of base salary. All matching contributions are currently 100% vested immediately. The Company reserves the right to modify its policies at any time, including increasing, decreasing, or eliminating contribution matching and vesting requirements. Total Company contributions in fiscal years 20152016, 20142015, and 20132014 were$4.7 million, $4.5 million, $4.2 million, and $4.04.2 million, respectively.

14.15.FOREIGN CURRENCY DERIVATIVES

The Company's foreign currency derivatives consist primarily of foreign currency forward exchange contracts, option contracts, and cross-currency swaps.  The derivatives expose the Company to credit risk to the extent the counterparties may be unable to meet the terms of the derivative instrument.  The Company's maximum exposure to loss due to credit risk that it would incur if parties to derivative contracts failed completely to perform according to the terms of the Company's agreements was equal to the net asset value of the Company's derivatives as of March 31, 20152016.  The Company seeks to mitigate such risk by limiting its counterparties to several large financial institutions.  In addition, the Company monitors the potential risk of loss with any single counterparty resulting from this type of credit risk on an ongoing basis.

The Company enters into master netting arrangements with counterparties when possible to mitigate credit risk in derivative transactions. A master netting arrangement may allow each counterparty to net settle amounts owed between Plantronics and the counterparty as a result of multiple, separate derivative transactions. As of March 31, 20152016, the Company has International Swaps and Derivatives Association (ISDA) agreements with four applicable banks and financial institutions which contain netting provisions. Plantronics has elected to present the fair value of derivative assets and liabilities within the Company's consolidated balance sheet on a gross basis even when derivative transactions are subject to master netting arrangements and may otherwise qualify for net presentation. However, the following tables provide information as if the Company had elected to offset the asset and liability balances of derivative instruments, netted in accordance with various criteria in the event of default or termination as stipulated by the terms of netting arrangements with each of the counterparties.

59


For each counterparty, if netted, the Company would offset the asset and liability balances of all derivatives at the end of the reporting period. Derivatives not subject to master netting agreements are not eligible for net presentation. As of March 31, 20152016 and March 31, 20142015, no cash collateral had been received or pledged related to these derivative instruments.

Cash Flow Hedges
 
Costless Collars

The Company hedges a portion of the forecasted EUR and GBP denominated revenues with costless collars. On a monthly basis, the Company enters into option contracts with a ninesix to eleven month term.  Collar contracts are scheduled to mature at the beginning of each fiscal quarter, at which time the instruments convert to forward contracts. The Company also enters into cash flow forwards with a three month term. Once the hedged revenues are recognized, the forward contracts become non-designated hedges to protect the resulting foreign monetary asset position for the Company.

The Company does not purchase options for trading purposes.  As of March 31, 2015,2016, the Company had foreign currency put and call option contracts of approximately €67.9€59.4 million and £28.6£18.4 million.  As of March 31, 20142015, the Company had foreign currency put and call option contracts of approximately 55.767.9 million and £23.928.6 million. As of March 31, 2016  the Company had foreign currency forward contracts of approximately €23.9 million and £9.1 million. As of March 31, 2015, the company had no such instruments. The Company will reclassify all amounts accumulated in other comprehensive income into earnings within the next twelve months.

Cross-currency Swaps

The Company hedges a portion of the forecasted Mexican Peso (“MXN”) denominated expenditures with a cross-currency swap. A loss of $3.1$1.1 million, net of tax, in AOCI as of March 31, 20152016 is expected to be reclassified to net revenues during the next 12 months due to the recognition of the hedged forecasted expenditures. As of March 31, 20152016 and 2014,2015, the Company had foreign currency swap contracts of approximately MXN 431.9481.0 million and MXN 204.6431.9 million, respectively.

The effective tax rate for fiscal years 2016, 2015, and 2014 and 2013 was 16.8%, 22.7%, 20.4%, and 23.1%20.4% respectively. The effective tax rate for fiscal year 2016 is lower than that in the previous year due primarily to domestic interest expense on new debt and tax benefits associated with the unwind of prior intercompany cost-sharing of stock based compensation. A retroactive and permanent reinstatement of the federal research credit was signed into law on December 18, 2015. As such, the Company's effective tax rate for fiscal year 2016 includes the benefit of one quarter of credits for fiscal year 2015 isplus the tax benefit for the fiscal year 2016 tax credit.

In comparison to fiscal year 2014, the effective tax rate for fiscal year 2015 was higher than the previous year due primarily to the absence of several one-time, discrete items that benefited the tax rate in the previous year, such as the generation of a foreign tax credit carryover, changes in Mexican tax law that resulted in the reversal of a valuation allowance, and a deduction for qualifying domestic production activities. These factors wereThis factor was offset by a higher proportion of income earned in foreign jurisdictions that is taxed at lower rates and by an increase in the benefit from the U.S. federal research tax credit. Our fiscal year 2015 included four quarters of benefit from the U.S. federal research tax credit because the credit expired on December 31, 2014 but was retroactively reinstated in January 2015. In contrast, during our fiscal year 2014, the credit was only available for three quarters as the credit expired December 31, 2013 and was not renewed.

In comparison to fiscal year 2013, the decrease in the effective tax rate for fiscal year 2014 was due primarily to changes in Mexican tax law that resulted in the reversal of a valuation allowance, a deduction for qualifying domestic production activities, and the generation of a foreign tax credit carryover, offset by a decrease in the benefit from the U.S. federal research tax credit. The U.S. federal research tax credit expired December 31, 20132014, and fiscal year 2015 included four quarters of benefit because of the impact of the credit earned in our fourth quarter of fiscal year 2014 due to the retroactive reinstatement of the credit in January 2015. However, in fiscal year 2014, this credit was therefore only available for three quarters in our fiscal year 2014, compared to fiscal year 2013, which included a full five quarters of benefit. Five quarters of benefit was recorded in fiscal year 2013 due tosince the timing of the retroactive reinstatement of the U.S. federal research tax credit. On January 2, 2013, the American Taxpayer Relief Act of 2012, which included a provision that retroactively extended the federal tax research credit to January 1, 2012 for two years, was signed into law. The Company recognized an approximate $1.8 million discrete tax benefit in the fourth quarter of fiscal year 2013 for the previously expired period from January 1, 2012 to December 31, 2012.2013 prior to it being retroactively reinstated in January 2015.

The effective tax rate for fiscal years 2016, 2015,, 2014, and 20132014 differs from the statutory rate due to the impact of foreign operations taxed at different statutory rates, income tax credits, state taxes, and other factors.  The future tax rate could be impacted by a shift in the mix of domestic and foreign income, tax treaties with foreign jurisdictions, changes in tax laws in the U.S. or internationally, or a change in estimate of future taxable income which could result in a valuation allowance being required.

The Company's provision for income taxes does not include provisions for U.S. income taxes and foreign withholding taxes associated with the repatriation of undistributed earnings of certain foreign operations that it intends to reinvest indefinitely in the foreign operations. Indefinitely reinvested foreign earnings were approximately $650.8$657.3 million at March 31, 2015.2016. The determination of the tax liability that would be incurred if these amounts were remitted back to the U.S. is not practical but would likely be material. If these earnings were distributed to the U.S. in the form of dividends or otherwise, the Company would be subject to additional U.S. income taxes, subject to an adjustment for foreign tax credits and foreign withholding taxes.

On July 27, 2015, the United States Tax Court, in an opinion in Altera Corp. v. Commissioner, invalidated the portion of the Treasury regulations issued under IRC Section 482 requiring related-party participants in a cost sharing arrangement to share stock-based compensation costs. The Company's current plans doU.S. Tax Court issued the final decision on December 28, 2015. The government filed a notice of appeal within the required 90 day period following the final decision. At this time, the U.S. Treasury has not requirewithdrawn the requirement to include stock-based compensation from its regulations. The Company has considered the issue and has recorded a tax benefit of $2.9 million resulting from the reimbursement of prior cost sharing of stock based compensation, offset by the U.S. tax cost of repatriation of the associated foreign earnings from foreign operationsfor which it has recorded a deferred tax liability in the current period. The Company will continue to fundmonitor developments related to the U.S. operations because it generates sufficient domestic operating cash flowcase and has access to external funding under its line of credit. As a result, the Company does not expect a materialpotential impact on its business orconsolidated financial flexibility with respect to undistributed earnings of its foreign operations.statements.

Deferred tax assets and liabilities represent the tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting and income tax purposes.  Effective for the fourth quarter of fiscal year 2016, the Company early adopted the update to balance sheet classification of deferred taxes (Accounting Standards Update 2015-17), which simplifies the presentation of deferred income taxes by requiring deferred tax assets and liabilities be classified as non-current on the balance sheets. The Company early adopted this standard on a prospective basis and included the current portion of deferred tax assets within the non-current portion of deferred tax assets within the consolidated balance sheet as of March 31, 2016. There was no impact on the Company's results of operations as a result of the adoption of this standard.

Significant components of the Company's deferred tax assets and liabilities as of March 31, 20152016 and 20142015 are as follows:

(1) The Company's deferred tax assets for the fiscal year ending March 31, 2016 and the long-term portion of the Company's deferred tax assets for the fiscal yearsyear ending March 31, 2015, and March 31, 2014, are included as a component of other assets on the consolidated balance sheets.


The Company evaluates its deferred tax assets, including a determination of whether a valuation allowance is necessary, based upon its ability to utilize the assets using a more likely than not analysis.  Deferred tax assets are only recorded to the extent that they are realizable based upon past and future income.  The Company has a long established earnings history with taxable income in its carryback years and forecasted future earnings.  The Company has concluded that no valuation allowance is required, except for the specific items discussed below.

The valuation allowance of $1.9$2.0 million as of March 31, 20152016 was related to the net operating losses of a foreign subsidiary with an insufficient history of earnings to support the realization of the deferred tax asset.
The impact of an uncertain income tax position on income tax expense must be recognized at the largest amount that is more likely than not to be sustained.  An uncertain income tax position will not be recognized unless it has a greater than 50% likelihood of being sustained.  As of March 31, 20152016, 2014,2015, and 2013,2014, the Company had $12.812.7 million, $12.612.8 million, and $11.112.6 million, respectively, of unrecognized tax benefits.  The unrecognized tax benefits as of March 31, 20152016 would favorably impact the effective tax rate in future periods if recognized.

A reconciliation of the change in the amount of gross unrecognized income tax benefits for the periods is as follows:
 March 31, March 31,
(in thousands) 2015 2014 2013 2014 2015 2016

 $12,571

 $12,821

The Company's continuing practice is to recognize interest and penalties related to income tax matters in income tax expense. The interest related to unrecognized tax benefits was $1.81.6 million and $1.71.8 million as of March 31, 20152016 and 2014,2015, respectively. No penalties have been accrued.

The Company and its subsidiaries are subject to taxation in various foreign and state jurisdictions, including the U.S. The Company is under examination by the Internal Revenue ServiceAll federal tax matters have been concluded for its 2010 tax year.years prior to fiscal year 2013. The California Franchise Tax Board completed its examination of our 2007 and 2008 tax years. The Company received a Notice of Proposed Assessment and responded by filing a protest letter. The amount of the proposed assessment is not material. Foreign income tax matters for material tax jurisdictions have been concluded for tax years prior to fiscal year 2011, except for the United Kingdom, which has been concluded for tax years prior to fiscal year 2014.2015.

The Company believes that an adequate provision has been made for any adjustments that may result from tax examinations; however, the outcome of such examinations cannot be predicted with certainty. If any issues addressed in the tax examinations are resolved in a manner inconsistent with the Company's expectations, the Company could be required to adjust its provision for income tax in the period such resolution occurs. The timing of any resolution and/or closure of tax examinations is not certain.

16.17.COMPUTATION OF EARNINGS PER COMMON SHARE

The Company has a share-based compensation plan under which employees, non-employee directors, and consultants may be granted share-based awards, including shares of restricted stock on which non-forfeitable dividends are paid on unvested shares. As such, shares of restricted stock are considered participating securities under the two-class method of calculating earnings per share as described in the Earnings per Share Topic of the FASB ASC.share. The two-class method of calculating earnings per share did not have a material impact on the Company's earnings per share calculation as of March 31, 2015201620142015, and 20132014.
