We believe important drivers for the adoption of our solutions include:

expansion of business applications and ecosystems with integrated web-based video and content collaboration that demand interoperability;

virtualization and accelerated adoption of private, public, and hybrid clouds and the resulting customer desire for cloud management tools;

ease of use and ease of deployment;

global growth of open office environments, small conference and huddle rooms, and the number of mobile and remote workers, with video as a preferred method of communication;

adoption of UC&C by small and medium-sized business (SMBs); and

continued commitment by organizations and individuals to reduce their expenses and carbon footprint by choosing voice, video and content collaboration over travel.

We believe we are uniquely positioned as the UC&C ecosystem partner of choice through our strategic partnerships, support of open standards, innovative technology, multiple delivery modes, and customer-centric go-to-market capabilities.

We leverage state-of-the-art technologies in our solutions that can be easily used in conjunction with our strategic partners' tools and common communication platforms in both personal and enterprise settings. The increased adoption of new and existing technologies such as UC&C, Bluetooth, Voice over Internet Protocol ("VoIP"), Digital Signal Processing ("DSP"), and Digital Enhanced Cordless Telecommunications (“DECT™”), and Video-as-a-Service ("VaaS"), each of which is described below, has contributed to increased demand for our headsets and audio solutions:

UC&C is the integration of voice, data, chat, and video-based communications systems enhanced with software applications and IPInternet Protocol (IP) networks.  It may include the integrationincludes more traditional unified communications consisting of devices and media associated with a variety of business workflows and applications, includingon-premise IP telephony, such as e-mail, instant messaging, presence information, audio and video conferencing, and unified messaging.messaging; and more modern team collaboration consisting of cloud-based persistent chat and team workspaces, integrated UC and application integrations; as well as browser-based online meetings consisting of integrated audio, video, and web conferencing. UC&C 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/orand 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 Internetinternet connection instead of a regular (or analog) telephone line.  VoIP converts the voice signal into a digital signal that travels over the Internetinternet 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 towhich improve both transmit and receivetransmission quality.

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

Product Categories

Our productsaudio and video solutions are designed to meet the needs of open offices (ranging from enterprise to home offices), contact centers, mobile devices (such as cubicles for knowledge workers and contact centers), meeting rooms (from huddle rooms to boardrooms), mobile workers (using laptops, mobile phones, smartphones, and tablets)tablets in or out of the office), computerback-offices (for management, monitoring and analytics of our systems), PC 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 Headsets

TheWithin our Enterprise market comprises our largest revenue stream andHeadsets product category, we believe it also represents our largest revenue and profit growth opportunity. We offer a broad range of communications headsets,audio solutions, including high-end, ergonomically designed headsets, audio processors, and telephoneother contact center systems.  Our end-users consistare comprised of enterprise employees and small office, home office, contact center, and remote workers. Growth in this categorymarket comes from the following three main factors:

Increasingincreasing deployment of UC&C solutions
Robust job market
Growing and growing awareness of the benefits of using headsets including the benefits ofand wireless solutionssolutions.

The contact center category is theContact centers are some of our most mature in which we participate,customers and we expect this category to grow slowly over the long-term.  Contact centers have begun to adopt cloud applications and services as an enabler for digital transformation to support an omni-channel model for customer interaction that can also include the deployments of softphones and web-based UC&C capabilities 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 Headsets

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 devices represents a high volume opportunity

Revenues from our Consumer Headsets product category are seasonal and istypically strongest in our second largest revenue stream.  The use of mono headsets typically used with mobile devices has experienced a sharp decline overthird fiscal quarter, which includes 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 believeholiday shopping season. Other factors that style has become as important as functionality in shaping consumers' purchasing decisionsdirectly impact performance in the wearable technology space.  While growthproduct category include product life cycles (including the introduction and pace of adoption of new technology), market acceptance of new product introductions, consumer preferences and the competitive retail environment, changes in the mono mobile headset market has slowedconsumer confidence and continues to mature, we believe future growth will be driven primarily by demand for stereo Bluetooth technology.other macroeconomic factors.

GamingWe also sell gaming and computer audio headsets, whethersold under our RIG sub-brand, used for interactive on-line orand console gaming, or switchingthat allow users to switch between music and phone calls for multi-functional devices.

In an effort to align our strategy and focus on our core enterprise markets, we announced on May 7, 2019 that we intend to evaluate strategic alternatives for our Consumer Headset products. We have not yet determined the timing, structure, or financial impact of any potential transaction.

FOREIGN OPERATIONS
 
In fiscal years 2016, 2015,Fiscal Years 2017, 2018, and 2014,2019, net revenues outside the U.S. accounted for approximately 44%45%, 44%49%, and 42%53%, 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 2016, internationalThe impact to consolidated net revenues were reduced by approximately $27 million, net of the effects of hedging, due to unfavorableresulting from changes in foreign exchange fluctuationsrates was not material in the other foreign currencies in which we sell.Fiscal Year 2019.

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 2017,Fiscal Year 2020, 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, our results may be adversely impacted by future changes in foreign currency exchange rates relative to original hedging contracts generally secured 12 to 24 months prior.

These competitors include, Cisco Systems, Inc., Avaya Inc., ClearOne Communications, Inc., Huawei Technologies Co., Ltd., Logitech International S.A., GN Netcom, LifeSize Inc., Snom Technology GmbH, Vidyo, Inc., Yamaha Corporation/Revolabs, Inc., Yealink Network Technology Co., Ltd., ZTE Corporation, Grandstream Networks, Aver Information, Inc., Sennheiser Communications and others. In some cases, we also cooperate and partner with these companies in programs and various industry initiatives.
One of our primary competitors in the Enterprise Headsets and Consumer Headsets areas and, to a lesser extent, in the gaming and PC audio areas 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.conglomerate.  In addition, Motorola, Samsung, and LG are significant competitors in the consumer mono Bluetooth headset category. Sennheiser Communications VXI, and regional companies are competitors in the computer, office, and contact center categories, while Beats,Apple, Skullcandy, Logitech, Bose, and LG are competitors in the stereo Bluetooth headset category.  In addition, Turtle Beach, Skullcandy, Logitech, and Razer are competitors in the gaming category.


Our main competitors in the Voice and Video categories consists of both larger companies, such as Cisco Systems, with substantial financial resources and more sizable sales, marketing, engineering and other capabilities with which to develop, manufacture, market, and sell their solutions, and smaller niche competitors. Our strategy of offering a best-in-class complete portfolio of UC voice and video endpoints faces challenges from competitors, who create end-to-end service and endpoint solutions, as well as low cost competitors in specific categories, or other industry players, who are potentially able to develop unique technology or compete in a specific geography.

For Services, some of our partners resell our maintenance and support services, while others sell their own branded services. To the extent that channel partners sell their own services, these partners compete with us; however, they typically purchase maintenance contracts from us to support these services. As we expand our professional services offering, we may compete more directly with partners in the future.

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

Understanding of emerging trends and new communication technologies, such as UC&C and VaaS, and our ability to react quickly to the opportunities they provide
Alliances and integration/compatibility with major UC&C vendors
Ability to design, manufacture, and sell products that deliver on performance, style, ease-of-use, comfort, features, sound quality, interoperability, simplicity, price, and reliability
Ability to create and monetize software solutions that provide management and analytics and allow business to improve IT and employee performance through insights derived from our analytics.
Brand name recognition and reputation
Superior global customer service, support, and warranty terms
EffectiveGlobal reach, including effective and efficient global distribution channels
Global reach

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

RESEARCH AND DEVELOPMENT
 
The success of our new product introductionsproducts is dependent on a number ofseveral factors, including appropriate new product selection,identifying and designing products that meet anticipated market demand before it has developed and as it matures, timely completiondevelopment and introduction of these products, cost-effective manufacturing, quality and durability, acceptance of new technologies, and general market acceptance.acceptance of the products we develop.  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,We face risks associated with developing and marketmarketing our products, including new products in response to changing customer requirementsproduct development and new technologies"product line" within Item 1A Risk Factors in this Form 10-K.

During fiscal years 2016, 2015, and 2014, we incurred approximately $90.4 million, $91.6 million, and $84.8 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 thea 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. India.

During fiscal year 2016,Fiscal Year 2019, 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 haveutilizing 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 developingdevelop require significant technological knowledge and speedthe ability to market. Separately or together, thisrapidly develop the products in intensely competitive and transforming markets. We believe our extensive technological knowledge and ourportfolio of intellectual property gives us a competitive advantage. We furthermore 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 global customer support and service globally.service.  To support our partners in the Enterprise market and their customers' needs, we have a well-established, multi-leveltwo-tiered distribution network in North America,the Americas, Europe, Middle East and Africa, and Asia Pacific regions 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.select markets, direct resellers.

Our global commercial sales channel network includes technologyenterprise distributors, direct and electronics distributors,indirect resellers, retailers, network 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.
Our retail channel consists of bothsystems integrators, service providers, traditional and online consumer electronics retailers, consumer product retailers, office supply distributors, wireless carriers, catalog and mail order companies, and mass merchants.

In addition, we have built a strong foundation of alliance partners, which allow existing and future distribution and reseller partners to sell into Microsoft, Zoom, Google and other service provider environments. Our commercial distribution channel maintains an inventory of our products.  Our distribution of specialty products includes retail, government programs, customer service, hospitality and healthcare professionals. Plantronics branded consumer 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 customerTwo customers, ScanSource and Ingram Micro Group, accounted for more than 10%16.0% and 11.4%, respectively, of our consolidated net revenues in fiscal years 2016, 2015, or 2014.

Our distributors, resellers, system integrators, e-commerce partners, telephony and computer equipment providers resell our commercial headsets and end point products.

One customer, Ingram Micro Group, accounted 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 portion10.9% of ourconsolidated net revenues in fiscal years 2016, 2015, or 2014. In addition, certain distributors are authorized resellers under a GSA schedule price listFiscal Years 2018 and sell our products to government customers pursuant to that agreement.2017. 

We have also established strong UC alliances with leading providersSome 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.comwww.poly.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:

BACKLOG
 
Our backlog of unfilled orders was $23.4 million and $24.3 million at March 31, 2016 and 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 ofmost orders within 48 hours of receipt of the order.receipt. 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 customercustomers 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,Consequently, 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, testing, and testing, both ofpackaging, which are performed in our manufacturing facility in Tijuana, Mexico.  We outsource the manufacturing of most of our Bluetooth products to third party manufacturers in China.

ITEM 1A.  RISK FACTORS
YOU SHOULD CAREFULLY CONSIDER THE RISKS DESCRIBED BELOW BEFORE MAKING AN INVESTMENT DECISION. THE RISKS DESCRIBED BELOW ARE NOT THE ONLY ONES WE FACE. ADDITIONAL RISKS THAT WE ARE NOT PRESENTLY AWARE OF OR THAT WE CURRENTLY BELIEVE ARE IMMATERIAL MAY ALSO IMPAIR OUR BUSINESS OPERATIONS. OUR BUSINESS COULD BE MATERIALLY HARMED BY ANY OR ALL OF THESE RISKS. THE TRADING PRICE OF OUR COMMON STOCK COULD DECLINE SIGNIFICANTLY DUE TO ANY OF THESE RISKS, AND YOU MAY LOSE ALL OR PART OF YOUR INVESTMENT. IN ASSESSING THESE RISKS, YOU SHOULD ALSO REFER TO THE OTHER INFORMATION CONTAINED OR INCORPORATED BY REFERENCE IN THIS ANNUAL REPORT ON FORM 10-K, INCLUDING OUR CONSOLIDATED FINANCIAL STATEMENTS AND RELATED NOTES.
You should carefully consider
The failure to successfully integrate the following risk factorsbusiness and operations of Polycom in connectionthe expected time frame and achieve the expected synergies may adversely affect the business and financial results of the combined company.

We believe the acquisition of Polycom, which was completed on July 2, 2018, will result in certain benefits, including acceleration and expansion of our market opportunities, creation of a broad portfolio of communications and collaboration endpoints, significant expansion of services offerings, accretion to diluted earnings per common share, and significant operational efficiencies and cost synergies. However, our ability to realize these anticipated benefits depends on the successful integration of the two businesses. The combined company may fail to realize the anticipated benefits of the acquisition for a variety of reasons, including the following:

the inability to integrate the businesses in a timely and cost-efficient manner or do so without adversely impacting revenue, operations, including new product launches and cash flows;
expected synergies or operating efficiencies may fail to materialize in whole or part, or may not occur within expected time-frames;
the failure to successfully manage relationships with each company’s historic customers, resellers, end-users, suppliers and strategic partners and their operating results and businesses generally (including the diversion of management time to react to new and unforeseen issues);
the failure or inability to timely and efficiently integrate network infrastructures including pricing and ordering systems without materially adversely impacting the timing and processing of orders which could harm our relationships with suppliers, vendors, customers and end users;
the failure to accurately estimate the potential markets and market shares for the combined company’s products, the nature and extent of competitive responses to the acquisition and the ability of the combined company to achieve or exceed projected market growth rates;
the inability to attract key personnel or to retain key personnel with unique talents, expertise or background knowledge as a consequence of both voluntary and involuntary employment actions;
the failure to successfully advocate the benefits of the combined company for existing and potential end-users, customers, and resellers or general uncertainty regarding the value proposition of the combined entity or its products;
the failure to effectively compete against larger companies or companies with well-established market shares in the broader markets expected to be served by the combined company or the perceived threat by competitors that the combined company represents to their existing markets;
difficulties forecasting financial results, particularly in light of distinct business cycles between the two companies with a significantly higher proportion of Polycom’s quarterly bookings and revenues being recognized in the third month of each quarter, making the timing of revenue and expenses more difficult to predict and providing accurate guidance to financial analysts and investors less certain;
outcomes or rulings in known or as yet to be discovered regulatory enforcement, litigation or other similar matters that are, alone or in the aggregate, materially adverse;
negative effects on the market price of our common stock as a result of the transaction, particularly in light of the amount of debt incurred, our ability to timely pay down such debt, restrictions placed on our operations as result of covenants related to the debt, as well as the number of shares of our stock issued in the transaction and any investmentsubsequent sales of that stock by the seller, and forecasts and expectations of analysts;
failures in our stock.  financial reporting including those resulting from system implementations in the context of the integration, our ability to report or forecast financial results of the combined company and our inability to successfully discover and assess and integrate into our reporting system, any of which may adversely impact our ability to make timely and accurate filings with the SEC and other domestic and foreign governmental agencies;
difficulties integrating professional services revenue streams with historic hardware sales and subscription services without adversely impacting revenue recognition;
the potential impact of the transaction on our future tax rate and payments based on our global entity consolidation efforts and our ability to quickly and cost effectively integrate foreign operations;
the challenges of integrating the supply chains of the two companies; and

the potential that our due diligence did not fully uncover the risks and potential liabilities of Polycom.

The actual integration may result in additional and unforeseen expenses or delays, distract management from other revenue or acquisition opportunities, and increase the combined company’s expenses and working capital requirements, particularly in the short-term. If we are unable to successfully integrate Polycom's business and operations in a timely manner, the anticipated benefits of the acquisition may not be fully realized, or at all, or may take longer to realize than anticipated. Should any of the foregoing or other currently unanticipated risks arise, our business and results of operations may be materially adversely impacted.

Competition in each of our markets is strong, and our inability to compete effectively could significantly harm our business and results of operations.

We face strong competition in the Americas, E&A, and APAC in all of the markets for our products, solutions and services. Market leadership changes may occur as a result of numerous factors, including new product and technology introductions, new market participants, pricing pressure on average selling prices and sales terms and conditions, and related to product performance and functionality. For a further description of our competitors and the markets in which we compete, see Item 1, Business, in this Form 10-K.

Our stock price will reflectcompetitive landscape continues to rapidly evolve as the industry moves into new markets for collaboration such as mobile, browser-based, and cloud-delivered collaboration offerings. Competitors in these markets also continue to develop and introduce new technologies, sometimes proprietary or closed architectures, that may block or limit our ability to compete in certain markets. Many of our competitors are larger, offer broader product lines, may integrate their products and solutions with communications solutions, devices, and adapters manufactured or provided by them or others, offer products or solutions incompatible with our products, have established market positions, and have substantially greater financial, marketing, and other resources; all of which may increase pressure to reduce our pricing, increase our spending on sales and marketing, or both, which would correspondingly have a negative impact on our revenues and operating margins.
We may not be able to compete successfully against our current or future competitors. We expect our competitors to continue to improve the performance of their current products and to introduce new products or new technologies that provide improved performance. New product introductions by our business relativecurrent or future competitors, or our delay in bringing new products to among other things,market, could cause a significant decline in sales or loss of market acceptance of our products. We believe that ongoing competitive pressure may result in a reduction in the prices of our products and our competitors’ products. In addition, the introduction of additional lower priced competitive products or of new products or product platforms could render our existing products or technologies obsolete. We also believe we will face increasing competition expectationsfrom alternative UC&C endpoint solutions that employ new technologies or new combinations of securities analysts or investors,technologies.
Further, the commoditization of certain headset and general economicvideoconferencing products is leading to the availability of alternative, lower cost competitive products targeted to enterprises, consumers and small businesses, which could harm sales.  If we do not distinguish our products, through distinctive, technologically advanced features and designs, as well as continue to build and strengthen our brand recognition, our products may become commoditized.  In addition, failure to effectively market our products could lead to lower and industry conditions.  Ourmore volatile revenue and earnings, excess inventory, and the inability to recover associated development costs, any of which could have a material adverse effect on our business, financial condition, results of operations, and cash flows.
We also face competition from companies, principally located in or originating from the Asia Pacific region, offering low cost products, including products modeled on, direct copies of, or counterfeits of our products. 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 product prices are substantially reduced by new or existing market participants, our business, financial condition, or results of operations could be materially and adversely affected if anyaffected.
Increased consolidation and the formation of strategic partnerships in our industry may lead to increased competition, which could adversely affect our business and future results of operations.
Strategic partnerships and acquisitions are being formed and announced by our competitors on a regular basis, which increases competition and can result in increased downward pressure on our product prices. As a result, competition with larger combined companies with significantly greater financial, sales and marketing resources, a larger channel network and expanded product lines is a constant threat to our market share and revenues. Competitors can sell their communications solutions product lines in conjunction with proprietary network equipment or platform technology as a complete solution, making it more difficult to compete against them or to ascertain pricing on competitive products. In addition, some competitors may use their strengths in adjacent markets to foreclose competition in the following risks occur.  Accordingly, the trading priceUC&C solutions market. In some cases, proprietary solutions may also preclude our competitive products from being fully interoperable with our competitors' endpoints, infrastructure and/or network products.

Acquisitions or partnerships made by one of our strategic partners could also limit the potential contribution of our strategic relationships to our business and restrict our ability to form strategic relationships with these companies in the future and, as a result, harm our business. Rumored or actual consolidation of our partners and competitors may cause uncertainty and disruption to our business and can cause our stock could decline, and investors could lose all or part of their investment.price to fluctuate.

Adverse or uncertain global and regional economic conditions may materially adversely affect us.

Our operations and financial performance are dependent on the global economy.and regional economies as well as industry specific trends and events. Uncertainty regarding future economic conditions makesand the markets into which we sell make it challenging both in the near and long-term 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,and Latin America regions, as well as anxiety regardingactual or potential geopolitical conflicts and their short and long-term economic impact, increase the uncertainty and unpredictability for our business as consumers, businesses and governmentgovernmental agencies periodically and often unpredictably postpone or forego spending. A global economic downturn, changes in the industries in which we sell our products, or continued erratic or declining business or governmental spending or hiring have in the past and may again in the future 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 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, limiting opportunities for unemployed workers to reenter the workforce and, consequently, impeding headset sales.

Additionally, althoughto the nature and extent of austerity measures previously implemented by governments implement general or specific reductions in various countries, including the U.S. and Europe, are less severe in recent fiscal periods, those that remain reduce,spending, demand for our products by affected governmentthose governmental agencies subject to the measures and by customers who derive all or a portion of their revenues from these agencies.agencies, may decline. Similarly, to the extent uncertainty regarding public debt limits or governmentgovernmental budgets particularly in the U.S and Europe, hinder spending by retail consumers, businesses or governmentgovernmental agencies, sales of our products may not grow as much as expectedbe materially harmed or may decrease or be delayed. We cannot predict the impact that governmental spending reductions 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 morein specific markets, customers or suppliers may demand pricing accommodations, delay payments, delays or shipmentscurtail prior deployment plans, 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.

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;
our ability to execute on our strategic and operating plans;
shifts in the timing, size and types of products ordered, as well as the mix of products and services, and the geographic locations of the customers placing orders, any of which could impact gross margins depending on the various margins of the products and services ordered and foreign currency exchange rates on both revenues and expenses;
the timing of customers' sales promotions and campaigns or variations in sales rates by our channel partner customers to their customers;
changes to our channel partner programs, contracts, pricing and go to market strategies that could: (i) result in a reduction in the number of channel partners; (ii) adversely impact our revenues and gross margins as we realign our discount and rebate programs for our channels; or (iii) cause more of our channel partners to add our competitors’ products to their portfolios;
the timing of large end customer deployments, including UC&C infrastructure;
the timing and market acceptance of new product introductions by us and our competitors and obsolescence or discontinuance of existing products;
competition, including pricing pressure, product features and functionality, by us, our competitors or our customers;
the level and mix of inventory that we hold to meet future demand;
changes to our global organization and retention of or changes in key personnel;
changes in effective tax rates which are difficult to predict due to, among other things, the timing and geographical mix of our earnings, the outcome of current or future tax audits and potential new rules and regulations;
failure to timely introduce new products within projected costs and reduce costs as production increases;
changes in technology and desired product features, including whether those changes occur as and when anticipated;
general economic conditions in the U.S. and our international markets, including foreign currency fluctuations;
seasonality, particularly as related to our retail channels during the December holiday season and our enterprise customers during our second fiscal quarter, particularly in Europe;
customer cancellations and rescheduling;

the impact of changing costs of freight and components used in the manufacturing of our products and the potential negative impact on our gross margins;
investments in and the costs associated with strategic initiatives;
changes in the underlying factors and assumptions used in determining stock-based compensation; and
changes in accounting rules or their interpretation.
As a result of these and potentially other factors, we believe that period-to-period comparisons of our historical results of operations are not necessarily a good predictor of our future performance. If our future operating results are below the expectations of stock market securities analysts or investors, or below any financial guidance we may provide to the market, our stock price will likely decline. Financial guidance beyond the current quarter is inherently subject to greater risk and uncertainty, and if the transitions in our markets accelerate, our ability to forecast becomes more difficult.

We have incurred significant indebtedness to finance the acquisition of Polycom, which will decrease our business flexibility and increase borrowing costs, which may adversely affect our operations and financial results.

Prior to the acquisition of Polycom, 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. In connection with the acquisition of Polycom, we borrowed an additional $1.275 billion, which was financed through a senior secured term loan bearing interest at LIBOR plus 250 bps maturing in July 2025 (the “Credit Agreement”) and replaced our existing line of credit agreement with a secured credit agreement. As a result, upon completion of the acquisition we increased our indebtedness in an amount materially greater than historical levels. The financial and other covenants in the Credit Agreement, our increased indebtedness and our higher debt-to-equity ratio have the effect, among other things, of:

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 liens or enter into certain types of transactions such as sale and lease-back transactions;
limiting our ability to borrow additional funds or to borrow funds at rates and terms we find acceptable; and
limiting our ability to repay or refinance the then-outstanding principal balance of any debt on maturity or to repay or refinance other future indebtedness.
In addition, our failure to comply with the covenants in the Credit Agreement could result in a default under the Credit Agreement and our other debt, which could permit the holders to accelerate such debt or demand payment in exchange for a waiver of such default. If any of our debt is accelerated, we may not have sufficient funds available to repay all or any portion of it when due.

Our current debt under the Credit Agreement has a floating interest rate that is based on variable and unpredictable U.S. and international economic risks and uncertainties and an increase in interest rates may negatively impact our financial results. We enter into interest rate hedging transactions that reduce, but do not mitigate, the impact of unfavorable changes in interest rates. There is no guarantee that our hedging efforts will be effective or, if effective in one period will continue to remain effective in future periods.

In addition, the mandatory debt repayment schedule of the Credit Agreement and the maturity our existing 5.50% Senior Notes in 2023 may negatively impact our cash position, further reduce our financial flexibility, and cause concerns with analysts and investors. Furthermore, any changes by rating agencies to our credit rating in connection with such indebtedness may negatively impact the value and liquidity of our debt and equity securities.

Were any of the risks referenced above or related risks were to occur, our operations and financial results may be materially and adversely impacted.

If we determine that our goodwill has become impaired, we could incur significant charges that would have a material adverse effect on our consolidated results of operations.

As a result of our acquisition of Polycom, the amount of goodwill and purchased intangible assets on our consolidated balance sheet and subject to future impairment testing increased substantially from $15.5 million at the end of fiscal year 2018 to more than $2.2 billion as of the end of the second quarter of fiscal year 2019. Goodwill represents the excess of cost over the fair market value of assets acquired in business combinations.

Goodwill impairment analysis and measurement requires significant judgment on the part of management and may be impacted by a wide variety of factors both within and beyond our control. For instance, any integration process may require significant time and resources, which may disrupt our ongoing business and thereby divert management’s attention from other critical

objectives, and we may be unable to successfully manage the integration. Additionally, we may not successfully evaluate or utilize the acquired technology or personnel, realize anticipated synergies from the acquisition, or accurately forecast the financial impact of the acquisition and integration, including accounting charges as well as any potential impairment of goodwill and intangible assets recognized in connection with any acquisition. Furthermore, fluctuations in the price of our stock, changes in applicable laws and regulations, including any that restrict the activities of Polycom or increase costs, and deterioration of market conditions could unfavorably impact goodwill.

We are required to annually test goodwill to determine if impairment has occurred, either through a quantitative or qualitative analysis. Additionally, interim reviews must be performed whenever events or changes in circumstances indicate that impairment may have occurred. If the testing performed indicates that impairment has occurred, we are required to record a non-cash impairment charge for the difference between the carrying value of the goodwill and the implied fair value of the goodwill in the period the determination is made. We cannot accurately predict the amount or timing of any impairment of assets. Should the value of our goodwill become impaired, it could have a material adverse effect on our consolidated results of operations and could result in our incurring potentially significant net losses in future periods.

The integration of the combined companies may result in significant expenses and accounting charges that adversely affect our operating results and financial condition.

In accordance with generally accepted accounting principles, we accounted for the acquisition of Polycom using the purchase method of accounting. Our financial results may be adversely affected by the resulting accounting charges incurred thereby and we expect to incur additional costs associated with combining the operations of the companies, which may be substantial. Additional costs may include: costs of employee redeployment; accelerated amortization of deferred equity compensation and severance payments; reorganization or closure of facilities; taxes; advisor and professional fees; and termination of contracts that provide redundant or conflicting services. We may be required to account for these costs as expenses that decrease our net income and earnings per share for the periods in which those adjustments are made. For example, for the fiscal year ended March 31, 2019, we recorded $68.7 million in acquisition and integration costs, which consisted primarily of costs for consulting services and other professional fees. The price of our common stock could decline to the extent our financial results are materially or unexpectedly affected by the foregoing charges and costs, or if future charges and costs are larger than anticipated.

Our corporate rebranding could cause confusion and harm our reputation, harming our business and results of operations.

In March 2019 we announced the rebranding of our company as “Poly.” As part of the effort, we adopted a new corporate brand identity and began efforts to promote the relaunch of the combined company. As we adopt and advertise our new brand, our customers, suppliers and the marketplace in general may not embrace the change, or it may cause confusion or it may take time to rebuild our reputation, name recognition and goodwill with our customers, suppliers and end users.  Moreover, our rebranding may adversely impact our ability to import and export products into one of more jurisdictions or create uncertainty with our customers (particularly with their ordering and accounts payable processes), which could harm our sales or delay our collections, thereby adversely affecting our business, financial condition or results of operations.

We face risks associated with developing and marketing our products, including new product development and new product lines.

Our success depends on our ability to assimilate new technologies in our products and to properly train our channel partners, sales force and end-user customers in the use of those products.

The markets for our products are characterized by rapidly changing technology, such as the demand for HD video technology and lower cost video infrastructure products, the shift from on premise-based equipment to a mix of solutions that includes hardware and software and the option for customers to have video delivered as a service from the cloud or through a browser, evolving industry standards and frequent new product introductions, including an increased emphasis on software products, new, lower cost hardware products, development of artificial intelligence and machine learning solutions that may make all or a portion of our products or their functionality obsolete or unnecessary. Historically, our focus has been on premise-based solutions for the enterprise and public sector, targeted at vertical markets, including finance, manufacturing, government, education and healthcare. In addition, in response to emerging market trends, and the network effect driven by business-to-business and business-to-consumer adoption of UC&C, we are expanding our focus to capture opportunities within emerging markets including mobile, small and medium businesses (“SMBs”), and cloud-based delivery. If we are unable to successfully capture these markets to the extent anticipated, or to develop the new technologies and partnerships required to successfully compete in these markets, then our revenues may not grow as anticipated and our business may ultimately be harmed. Given the competitive nature of the mobile industry, changing end user behaviors and other industry dynamics, these relationships may not evolve into fully-developed product offerings or translate into any future revenues.


The success of our new products depends on several factors, including proper new product definition, product cost, infrastructure for services and cloud delivery, timely completion and introduction of new products, proper positioning and pricing of new products in relation to our total product portfolio and their relative pricing, differentiation of new products from those of our competitors and other products in our own portfolio, market acceptance of these products and the ability to sell our products to customers as comprehensive UC&C solutions. Other factors that may affect our success include properly addressing the complexities associated with compatibility issues, channel partner and sales strategies, sales force integration and training, technical and sales support, and field support. As a result, it is possible that investments that we are making in developing new products and technologies may not yield the planned financial results. the failure to successfully and quickly integrate new and unique go to market sales strategies, channel partners and sales forces.

We also need to continually educate and train our channel partners to avoid any confusion as to the desirability of new product offerings and solutions compared to our existing product offerings and to be able to articulate and differentiate the value of new offerings over those of our competitors. As the market evolves, our distribution model and channel partners may change as well. During the last few years, we have announced and launched several new product offerings, both independently and jointly with our strategic partners, including new software, hardware and cloud-based solutions, and these new products could cause confusion among our channel partners and end-users, thereby causing them to delay purchases of our new products until they determine their market acceptance, or as they consider a more comprehensive UC&C strategy versus point product or endpoint only deployments. Any delays in future purchases could adversely affect our revenues, gross margins and operating results in the period of the delay.

The communications market shift to fully integrated solutions, cloud-based/hybrid offerings and new business models over time may require us to add new channel partners, enter new markets and gain new core technological competencies. We are attempting to address these needs and the need to develop new products through our internal development efforts, through joint developments with other companies and through acquisitions. However, we may not identify successful new product opportunities and develop and bring products to market in a timely manner. Further, as we introduce new products, these product transition cycles may not go smoothly, causing an increased risk of inventory obsolescence and relationship issues with our end-user customers and channel partners. The failure of our new product development efforts, any inability to service or maintain the necessary third-party interoperability licenses, our inability to properly manage product transitions or to anticipate new product demand, or our inability to enter new markets would harm our business and results of operations.

We may experience delays in product introductions and availability, and our products may contain defects which could seriously harm our results of operations.

We have experienced delays in the introduction of certain new products and enhancements in the past. The delays in product release dates that we experienced in the past have been due to factors such as unforeseen technology issues, manufacturing ramping issues and other factors, which we believe negatively impacted our revenue in the relevant periods. Any of these or other factors may occur again and delay our future product releases. Our product development groups are dispersed throughout the United States and other international locations such as China and India. As such, disruption due to geopolitical conflicts could create an increased risk of delays in new product introductions.

We produce highly complex communications equipment, which includes both hardware and software and incorporates new technologies and component parts from different suppliers. Resolving product defect and technology and quality issues could cause delays in new product introduction. Component part shortages could also cause delays in product delivery and lead to increased costs. Further, some defects may not be detected or cured prior to a new product launch or may be detected after a product has already been launched and may be incurable or result in a product recall. The occurrence of any of these events could result in the failure of a partial or entire product line or a withdrawal of a product from the market. We may also have to invest significant capital and other resources to correct these problems, including product reengineering expenses and inventory, warranty and replacement costs. These problems might also result in claims against us by our customers or others and could harm our reputation and adversely affect future sales of our products.

Any delays for new product offerings recently announced or currently under development, including product offerings for mobile, cloud-based delivery, software delivery or any product quality issues, product defect issues or product recalls could adversely affect the market acceptance of these products, our ability to compete effectively in the market, and our reputation with our customers, and therefore could lead to decreased product sales and could harm our business. We may also experience cancellation of orders, difficulty in collecting accounts receivable, increased service and warranty costs in excess of our estimates, diversion of resources and increased insurance costs and other losses to our business or to end-user customers.

Product obsolescence or discontinuance and excess inventory can negatively affect our results of operations.

The pace of change in technology development and in the release of new products has increased and is expected to continue to increase, which can often render existing or developing technologies obsolete. In addition, the introduction of new products and any related actions to discontinue existing products can cause existing inventory to become obsolete. These obsolescence issues,

or any failure by us to properly anticipate product life cycles, can require write-downs in inventory value. For each of our products, the potential exists for new products to render existing products obsolete, cause inventories of existing products to increase, cause us to discontinue a product or reduce the demand for existing products.

Further, we continually evaluate our product lines both strategically and in terms of potential growth rates and margins. Such evaluations could result in the discontinuance or divestiture of those products in the future, which could be disruptive and costly and may not yield the intended benefits.

We face risks related to the adoption rate of new technologies.

We have invested significant resources developing products that are dependent on the adoption rate of new technologies. For example, our Polycom®RealPresence® One and Polycom® RealPresence® Virtual Edition platform software solutions are dependent on enterprise adoption of software-based video bridging applications. If the software related video bridging market does not grow as we anticipate, or if our strategy for addressing the market, or execution of such strategy, is not successful, our business and results of operations could be harmed.

In addition, we develop new products or make product enhancements based upon anticipated demand for new features and functionality. Our business and revenues may be harmed if: (i) the use of new technologies that our future products are based on does not occur; (ii) we do not anticipate shifts in technology appropriately or rapidly enough; (iii) the development of suitable sales channels does not occur, or occurs more slowly than expected; (iv) our products are not priced competitively or are not readily adopted; or (v) the adoption rates of such new technologies do not drive demand for our other products as we anticipate. For example, although we believe increased sales of UC&C solutions will drive increased demand for our UC hardware and software platform products, such increased demand may not occur, or we may not benefit to the same extent as our competitors. We also may not be successful in creating demand in our installed customer base for products that we develop that incorporate new technologies or features. Conversely, as we see the adoption rate of new technologies increase, product sales of our legacy products may be negatively impacted, which could materially impact our revenues and results of operations.

Lower than expected market acceptance of our products, price competition and other price changes would negatively impact our business.

If the market does not accept our products, particularly our new product offerings on which we are relying on for future revenues, such as product offerings for platform software, new hardware products and cloud-based delivery, our business and operating results would be harmed. Further, revenues relating to new product offerings are unpredictable and new products typically have lower gross margins for a period of time after their introduction and higher marketing and sales costs. As we introduce new products, they could increasingly become a higher percentage of our revenues. Our profitability could also be negatively affected in the future as a result of continuing competitive price pressures in the sale of UC&C solutions equipment and UC platform products. Further, in the past we have reduced prices in order to expand the market for our products, and in the future, we may further reduce prices, introduce new products that carry lower margins in order to expand the market or stimulate demand for our products, or discontinue existing products as a means of stimulating growth in a new product.

Finally, if we do not fully anticipate, understand and fulfill the needs of end-user customers in the vertical markets that we serve, we may not be able to fully capitalize on product sales into those vertical markets and our revenues may, accordingly, fail to grow as anticipated or may be adversely impacted. We face similar risks as we expand and focus our business on the SMB and service provider markets.

Failure to adequately service and support our product offerings could harm our results of operations.

The increasing complexity of our products and associated technologies has increased the need for enhanced product warranty and service capabilities, including integration services, which may require us to develop or acquire additional advanced service capabilities and make additional investments. If we cannot adequately develop and train our internal support organization or maintain our relationships with our outside technical support providers, it could adversely affect our business.

In addition, sales of our immersive telepresence solutions are complex sales transactions, and the end-user customer may purchase an enhanced level of support service from us so as to ensure that its significant investment can be fully operational and realized. This requires us to provide advanced services and project management in terms of resources and technical knowledge of the customer’s telecommunication network. If we are unable to provide the proper level of support on a cost-efficient basis, it may cause damage to our reputation in this market and may harm our business and results of operations.


The success of our business depends heavily on our ability to effectively market our products, and our business could be materially adversely affected if markets do not develop as expected or we are unable to compete successfully.

We regard the markets for UC&C video and audio products as significant long-term opportunities. We believe the implementation of UC&C technologies by large enterprises will be a significant long-term driver of UC&C product 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&C market; however, there is no guarantee significant UC&C growth will occur, when it might occur, how competitors and partners may impact the development of the markets for UC&C products as they evolve or that we will successfully take advantage of opportunities in the UC&C markets if they do occur.

Our ability to realize and achieve positive financial results from Enterprise product sales, and UC&C sales in particular, could be adversely affected by a number of factors, including the following:

as UC&C becomes more widely adopted, competitors may offer solutions that effectively commoditize our headsets, which, in turn, may pressure us to reduce the prices of one or more of our products;
major platform providers may increase certification programs that drive certain software services and endpoint management towards their products and services, thereby limiting our ability to compete in certain markets;
the market success of major platform providers and strategic partners such as Microsoft Corporation, and our influence over such providers with respect to the functionality of their platforms and product offerings, their rate of deployment, their certification requirements, and their willingness to integrate their platforms and product offerings with our solutions, is limited. For example, Microsoft’s decision to transition from Lync to Skype for Business in early fiscal year 2016, and most recently from Skype for Business to Teams has proved to be a significant market transition that caused end customers to pause their deployment schemes or schedules while they assessed the implications of Microsoft’s decision;
failure to timely introduce solutions that are cost effective, feature-rich, stable, durable, and attractive to 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 with multiple devices;
failure of UC&C solutions generally, or our solutions in particular, to be adopted with the breadth and speed we 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&C solutions, including our products, have caused entities in various markets to reassess the data protection compliance and security safeguards of our devices;
failure of our sales model and expertise to support complex integration of hardware and software with UC&C infrastructure consistent with changing customer expectations;
increased competition for market share, particularly given that some competitors have superior technical and economic resources enabling them to take greater advantage of market opportunities;
sales cycles for more complex UC&C deployments are longer as compared to our traditional products;
our inability to timely and cost-effectively adapt to changes and future business requirements may impact our profitability in this market and our overall margins; and
failure to expand our technical support capabilities to support the complex and proprietary platforms in which our products are and will be integrated as well as increases in our support expenditures over time.

If our investments in, and strategic focus on, enterprise products and UC&C products in particular, do not generate incremental revenue, our business, financial condition, and results of operations could be materially adversely affected.

The markets for our Consumer headset products are volatile and our ability to compete successfully in one or more of these categories is subject to many risks.

Competition in the markets for our Consumer headset products, which consist primarily of Bluetooth headsets, gaming, entertainment and computer audio headsets, is intense and presents significant manufacturing, marketing and operational risks and uncertainties. The risks include the following:

the global market for mono Bluetooth headsets continues to decrease. The market for stereo Bluetooth headsets continues to grow, although it remains dominated by lifestyle brands. Our market share has been and is significantly larger in the mono Bluetooth than stereo Bluetooth market and thus far we have been unable to sufficiently increase share in the stereo Bluetooth market to offset decreases in the mono Bluetooth market.
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.
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 further shorten product lifecycles.

Failure to compete successfully in the Consumer headset markets may have an adverse effect on our business, results of operations, and financial condition.

If our own manufacturing facilities and those of our third-party 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 affected.

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 by us at our facility in Tijuana, Mexico and for us by third party original design manufacturers (“ODMs”) and contract manufacturers who obtain materials and sub-components from long and often complex chains of sub-suppliers. The cost, quality, and availability of the services, materials and components and finished products these ODMs, contract manufacturers, and third parties supply are essential to our success.

Our reliance on our manufacturing facility in Tijuana, Mexico, contract manufacturers, ODMs, and third parties involve significant risks, including the following:

we rely on suppliers for critical aspects of our business. For instance, we obtain a majority of our Bluetooth headset products from our ODM, Goertek, Inc. and our video products from our contract manufacturer, Celestica. Suppliers such as Goertek and Celestica may choose to discontinue supplying materials and components or finished products to us for a variety of reasons, including conflicting demands from their other customers, availability and price.
the accelerating pace of technological advancement by our suppliers and overall market competitiveness frequently makes it more difficult to obtain components in a timely manner and to continue to procure essential components and services like integrated circuits for our products. Any failure to obtain key components to meet our product roadmaps or customer demand may (i) require us to obtain a replacement supply of satisfactory quality which may be difficult, time-consuming, or costly, (ii) force us to redesign or end-of-life certain products, (iii) delay manufacturing, (iv) require us to make large last-time buys based on speculative long-term forecasts in excess of our short-term needs, holding materials and components or finished products in inventory for extended periods of time, or (v) being unable to meet customer demand. For instance, in fiscal year 2019 the global shortage of MLCC components, a material chip in a number of our products, impacted our ability to timely and completely fulfill orders and increased costs for the chips we were able to procure adversely impacted margins for those of our products incorporating the chips.
the lack of viable alternative sources of materials and components 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 orders for consumer products have shorter lead times than component lead times, making it necessary for us or our suppliers to carry more inventory in anticipation of orders, which may not materialize.
a 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, or risk of loss of, these materials and components until they are consumed in the production process. Our consignment 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 are generally 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, our inventory turn rate may decline or we could incur material unanticipated expenses, including write-downs for excess and obsolete inventory.

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, any of which could materially negatively impact our revenues, reduce profit margins, and harm relationships with affected customers. If 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 to meet demand may harm relationships with our customers. Further, if production is increased rapidly, manufacturing yields may decrease, which may also reduce our revenues or margins.
increased reliance upon our manufacturing facility in Tijuana, Mexico may cause disruption to the supply chain and change established supply chain relationships. We believe that a flexible supply chain allows us to effectively respond to customer demands but it also requires continuous improvement efforts involving management, production employees, and suppliers. If we are unable to consistently execute on our strategy, our ability to respond to customer demand profitability and timely may be harmed.

Any of the foregoing could cause us to be able to timely meet customer demand and thereby materially and adversely affect our business, financial condition, and results of operations.

Prices of certain raw materials and components 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 price fluctuations for 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 face risks related to our dependence on channel partners and strategic partners to sell our products.

Changes to our channel partner programs or channel partner contracts may not be favorably received and as a result our channel partner relationships and results of operations may be adversely impacted.

Our channel partners are eligible to participate in various incentive programs, depending upon their contractual arrangements with us. As part of these arrangements, we have the right to make changes in our programs and launch new programs as business conditions warrant. Further, from time to time, we may make changes to our channel partner contracts or realign our discount and rebate programs. For instance, following the acquisition of Polycom and partially as a consequence of the significant number of overlapping channel partners with inconsistent contractual terms between the two legacy Plantronics and Polycom entities, we embarked on a rationalization program designed to organize the channels serving our markets and harmonize the contractual terms under which we conduct business with these partners. These changes may upset our channel partners which could cause them to add competitive products to their portfolios, delay advertising or sales of our products, or shift their emphasis to selling our competitors’ products. Our channel partners may not be receptive to future changes, and we may not receive the positive benefits that we anticipate in making any program and contractual changes.

Our strategic partnerships with companies may not yield the desired results which could harm our business.

We are focusing on our strategic partnerships and alliances with traditional partners like Microsoft and new partners such as Google, Zoom, GoTo and others. Defining, managing and developing these partnerships is expensive and time-consuming and may not yield the desired results, impacting our ability to effectively compete in the market and to take advantage of anticipated future market growth. Our mobile solutions are also dependent on our ability to successfully partner with mobile device manufacturers.

In addition, as we enter into agreements with these strategic partners to enable us to continue to expand our relationships with these partners, we may undertake additional obligations, such as development efforts, which could trigger unintended penalty or other provisions in the event that we fail to fully perform our contractual commitments or could result in additional costs beyond those that are planned in order to meet these contractual obligations.

Conflicts between our channel partners and strategic partners could arise which could harm our business.

Some of our current and future products are directly competitive with the products sold by both our channel and strategic partners. As a result of these conflicts, there is the potential for our channel and strategic partners to compete head-to-head with us or to significantly reduce or eliminate their orders of our products or design our technology out of their products. Further, as a result of our increased efforts to sell through a direct-touch sales model, we may alienate some of our channel partners or cause a shift in product sales from our traditional channel model. Due to these and other factors, channel conflicts could arise which cause channel

partners to devote resources to the communications equipment of competitors, which would negatively affect our business and results of operations.

In addition, some of our products are reliant on strategic partnerships with call management providers and wireless UC&C platform providers. These partnerships result in interoperable features between products to deliver a total solution to our mutual end-user customers. Competition with our partners in all of the markets in which we operate is likely to increase, which would adversely affect our revenues and could potentially strain our existing relationships with these companies.

We are subject to risks associated with our channel partners’ sales reporting, product inventories and product sell-through.

We sell a significant amount of our products to channel partners who maintain their own inventory of our products for sale to resellers and end-users. Our revenue forecasts associated with products stocked by some of our channel partners are based largely on end-user sales reports that our channel partners provide to us. Although we believe this data has historically been generally accurate, to the extent that this sales-out and channel inventory data is inaccurate or not received timely, our revenue forecasts for future periods may be less reliable. Further, if these channel partners are unable to sell an adequate amount of their inventory of our products in a given quarter or if channel partners decide to decrease their inventories for any reason, such as a recurrence of global economic uncertainty and downturn in technology spending, the volume of our sales to these channel partners and our revenues would be negatively affected. In addition, we also face the risk that some of our channel partners have inventory levels in excess of future anticipated sales. If such sales do not occur in the time frame anticipated by these channel partners for any reason, these channel partners may substantially decrease the amount of product they order from us in subsequent periods, or product returns may exceed historical or predicted levels, which would harm our business and create unexpected variations in our financial results.

We are subject to risks associated with the success of the businesses of our channel partners.

Some of our channel partners that carry our products, and from whom we derive significant revenues, are thinly capitalized. Although we perform ongoing evaluations of their creditworthiness, the failure of these businesses to establish and sustain profitability, obtain financing or adequately fund capital expenditures could have a significant negative effect on our future revenue levels and profitability and our ability to collect our receivables. As we grow our revenues and our customer base, our exposure to credit risk increases. In addition, global economic uncertainty, reductions in technology spending in the United States and other countries, and periodic ongoing challenges in the financial services industry have in the past and may again in the future restricted the availability of capital, which may delay collections from our channel partners beyond our historical experience or may cause companies to file for bankruptcy, jeopardizing the collectability of our receivables from such channel partners and negatively impacting our future results.

Our channel partner contracts are typically short-term and early termination of these contracts may harm our results of operations.

We do not typically enter into long-term contracts with our channel partners, and we cannot be certain as to future order levels from our channel partners. In the event of a termination of one of our major channel partners, we believe that the end-user customer would likely purchase from another one of our channel partners, but if this did not occur and we were unable to rapidly replace that revenue source, its loss would harm our results of operations.

Our channel partners are impacted by changes in customer purchasing preferences which may adversely impact our traditional sales channels or the prices at which we may sell our products.

It is becoming easier for small online sellers of certain product categories 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. In turn, our traditional resellers may demand lower selling prices from us, more cooperative and marketing incentives, reduce their sales support needed to maintain our premium brand image, discontinue carrying our products and other similar adverse actions. As we begin to expand our offerings to include services, many of our historical channel partners may be unwilling or unable to market our services forcing us to establish new or different relationships. Further, increased competition among resellers may cause some of our resellers and partners to experience financial difficulties or force them to shut down, decreasing our channels to market. The inability to establish or maintain successful relationships with distributors, OEMs, retailers, and telephony service providers or to maintain quality distribution channels and sales models could materially adversely affect our business, financial condition, or results of operations.

If our channel partners fail to comply with laws or standards, our business could be harmed.

We expect our channel partners to meet certain standards of conduct and to comply with applicable laws, such as global anticorruption, anti-bribery, and import and export control laws. Noncompliance with standards or laws could harm our reputation

and could result in fines, penalties, injunctions, or other harm to our business and results of operations were we to become involved in an investigation due to non-compliance by a channel partner.

We have significant manufacturing, assembly and packaging operations in Mexico and rely on third party manufacturers located outside of U.S. which creates manufacturing and management risks that may limit our ability to timely and cost effectively deliver products to customers and thereby adversely impact our revenues or profitability.

We own and operate a manufacturing facility in Tijuana, Mexico, which is responsible for assembly of a significant portion of our Enterprise products from materials and components sourced from various suppliers in Asia and North America, and other suppliers. These risks are likely to increase as we expand our manufacturing operations in the facility subsequent to our acquisition of Polycom.

Our international operations are subject to a variety of risks, including political and economic instability, social unrest, the imposition of foreign tariffs and other trade barriers, restrictions on investments, taxation, exchange controls, capital controls, employment regulations and local labor market conditions, and impacts from foreign government laws and regulations and U.S. laws and regulations that apply to international operations. Increases in trade and social issues from the immigration crisis at the U.S. border may impact our ability to manufacture and deliver our products. We may also incur increased costs and experience delays or disruptions in product deliveries and payments in connection with international operations and sales that could cause loss or delays in collection of revenues.
A significant amount of our revenues are generated, and the majority of our product manufacturing and packaging occurs internationally, which subjects our business to risks of international sales, operations and trade.

International sales and manufacturing, marketing and sales expenses represent a significant portion of our revenues and operating expenses, and we anticipate that as a result of the acquisition of Polycom and other efforts our international sales and operating expenses will continue to increase. In fiscal year 2019, international revenues represented 53% of our total revenues. International sales and operations are subject to certain inherent risks, which would be amplified if our international business grows as anticipated, including the following:

recent economic sanctions imposed, and the potential for additional economic sanctions, by the United States as well as the actual and threatened retaliatory responses by impacted nations, some of which may affect or materially delay our ability to import or sell all or a portion of our products into impacted countries;
adverse economic conditions in international markets, such as the restricted credit environment and sovereign credit concerns in E&A and reduced government spending and elongated sales cycles;
information technology security, environmental and trade protection measures and other legal, regulatory and compliance obligations, some of which may result in fines, penalties and other legal sanctions or affect our ability to import our products, to export our products from, or sell our products in various countries where we are deemed to be in violation of our legal or contractual obligations;
the impact of government-led initiatives to encourage the purchase of products from domestic vendors or discourage relationships with certain entities, which can affect the willingness of customers or partners to purchase products from, or collaborate to promote interoperability of products with, companies headquartered in the United States;
unstable or uncertain political and economic situations such as the United Kingdom’s decision to leave the European Union;
the impact of changes in our international operations, including changes in key personnel;
compliance with global anticorruption laws such at the United States’ Foreign Corrupt Practices Act and United Kingdom’s Bribery Act, which may be exacerbated by cultural differences in the conduct of business in various regions;
foreign currency exchange rate fluctuations, including the recent volatility of the U.S. dollar, and the impact of our underlying hedging programs;
reduced intellectual property rights protections in some countries;
unexpected changes in regulatory requirements and tariffs;
longer payment cycles, greater difficulty in accounts receivable collection and longer collection periods; and
changes in tax law or interpretations thereof that could lead to potentially adverse tax consequences, such as legislation on revenue and expense allocations and transfer pricing among the Company’s subsidiaries.

Government policies on international trade and investments such as import quotas, capital controls, taxes or tariffs, whether adopted by individual governments or regional trade blocs, can delay or prohibit the import or export of our products, affect demand for our products and services, impact the competitiveness of our products or prevent us from manufacturing or selling products in certain countries. The implementation of more restrictive trade policies, including the imposition of tariffs, the imposition of more restrictive trade compliance measures, or the renegotiation of existing trade agreements by the U.S. or by countries where we sell our products and services or procure supplies and other materials incorporated into our products, including in connection with the

U.S. and Mexico border crisis, the increasing trade tensions and tariffs with China and Chinese threats of retaliation, and the U.K.'s pending withdrawal from the EU, could negatively impact our business.

Furthermore, international revenues may fluctuate as a percentage of total revenues in the future as we introduce new products. These fluctuations are primarily the result of our practice of introducing new products in North America first and the additional time and costs required for product homologation and regulatory approvals of new products in international markets. To the extent we are unable to expand international sales in a timely and cost-effective manner, our business could be harmed. We may not be able to maintain or increase international market demand for our products.

As we focus on growth opportunities, we are divesting or discontinuing non-strategic product categories and pursuing strategic acquisitions and investments, which could have an adverse impact on our business.

We continue to review our product portfolio and address our non-strategic product categories and products through various options including divestiture and cessation of operations like the sale of our Clarity division in 2017. If we are unable to effect divestitures on favorable terms or if realignment is costlier or distracting than we expect or has a negative effect on our organization, employees and retention, then our business and operating results may be adversely affected. Discontinuing products with service components may also cause us to continue to incur expenses to maintain services within the product life cycle or to adversely affect our customer and consumer relationships and brand. Divestitures may also involve warranties, indemnification or covenants that could restrict our business or result in litigation, additional expenses or liabilities. In addition, discontinuing product categories, even categories that we consider non-strategic, reduces the size and diversification of our business and causes us to be more dependent on a smaller number of product categories.

As we attempt to grow our business in strategic product categories and emerging market geographies, we will continue to consider growth through acquisitions or investments like the acquisition of Polycom as well as joint ventures. We will evaluate acquisition opportunities that could provide us with additional product or service offerings or with additional industry expertise, assets and capabilities. 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;
certain structures such as joint ventures may limit management or operational control because of the nature of their organizational structures;
difficulties integrating acquired operations, products, technology, internal controls, personnel and management teams;
dilutive issuances of our equity securities and incurrence of debt;
litigation;
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.

Moreover, any acquisitions may not be successful in achieving our desired strategic, product, financial or other objectives or expectations, which would also cause our business to suffer. Opposition to one of more acquisitions could lead to negative ratings by analysts or investors, give rise objections by one or more stockholders or result in shareholder activism, any of which could harm our stock price. (See the risk factor, “Our business could be negatively affected as a result of stockholder activism, and such stockholder activism could impact the trading price and volatility of our common stock” below). Acquisitions can also lead to large non-cash charges that can have an adverse effect on our results of operations as a result of write-offs for items such as future impairments of intangible assets and goodwill or the recording of stock-based compensation.

We are subject to other legal and compliance risks that could have a material impact on our business.

In foreign countries where we have operations, there are risks that our employees, contractors or agents could engage in business practices prohibited by U.S. laws and regulations applicable to us, such as the Foreign Corrupt Practices Act, or the laws and regulations of other countries, such as the UK Bribery Act. We maintain a global policy prohibiting such business practices and have in place a global anti-corruption compliance program designed to require compliance with, and uncover violations of, these laws and regulations. Nonetheless, we remain subject to risk that one or more of our employees, contractors or agents, including those located in or from countries where practices that may violate U.S. laws and regulations or the laws and regulations of other countries may be customary, will engage in business practices that are prohibited by our policies, circumvent our compliance

programs and, by doing so, violate such laws and regulations. Any such violations, even if prohibited by our internal policies, could adversely affect our business or financial performance and our reputation.

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 U.S. dollars and purchase a majority of our component parts from our supply chain in USD, whereas a significant portion of our sales are transacted in other currencies, particularly the Euro and the British Pound Sterling ("GBP"). If the USD strengthens further, it could further harm our financial condition and operating results in the future. Furthermore, fluctuations in foreign currency rates impact our global pricing strategy, which may result in our lowering or raising selling prices in one or more currencies in order to avoid disparityminimize disparities 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 during fiscal year 2015 and the continued strength of the USD throughout fiscal year 2016 negatively impacted our sales, pricing, margins, market share and operations overall. Should the dollar remain strong or strengthen further against foreign currencies, principally the Euro and the GBP, we may be compelled to raise prices for customers in the affected regions. Price increases may be unacceptable to our customers who could seekchoose to replace our products with lower pricedless costly alternatives in which case our sales and market share maywill be adversely impacted. Otherwise, ifIf we reduce prices to stay competitive in the affected regions, our profitability may be harmed. In fiscal year 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 additionaland allows unauthorized third party “grey market” resellers in varying countries whoto take advantage of price disparities, thereby undermining our premium brand image, established sales channels, and 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. VolatileAsia, and volatile or sustained increases or decreases in exchange rates ofbetween the U.S. Dollar and 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.

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 maintain foreign currency forward contracts denominated in Euros, GBP, Australian and AustralianCanadian 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 obsolescence 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 anticipated manners and timeframes;
general economic conditions in the U.S. and our international markets, including foreign currency fluctuations;
seasonality;
customer cancellations and rescheduling;
fluctuations in 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 expected 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 it 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 effectively commoditize our headsets, which, in turn, may pressure us to reduce the prices of one or more of our 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 decision to transition from Lync to Skype for Business in early fiscal year 2016 proved to be a more significant market transition than anticipated and caused end customers to modify or pause their deployment schemes or schedules while they assessed the implications of Microsoft’s decision.
Failure to timely introduce solutions that are cost effective, feature-rich, stable, and attractive to 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.
Failure of UC solutions generally, or our solutions in particular, to be adopted with the breadth and speed we 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 data 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 expectations.  
If new or evolving sales models such as our Software-as-a-Service, Device-as-a-Service or 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 do 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, decreasing product life cycles, and changes in demand. Production levels are generally forecasted based on anticipatednon-binding customer forecasts and historic product demand and we often place orders with suppliers for materials, components and componentssub-assemblies (“materials and components”) as well as finished products 13many weeks or more in advance of projected customer orders. Actual customer demand depends on many factors and may vary significantly from 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 couldmay result in higher inventories of raw materials, components, and sub-assemblies ("materials and components")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 materially 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 and 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 experienceas well as the likelihood of 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.
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 buysoperate in excess of our short-term needs, holding materials and components or finished products in inventory for extended periods of time. If 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 endeavor 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 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, which 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 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, in fiscal year 2015, sales of our BackBeat Fit were constrained by limited sub-component supply availability. If similar constraints were to occur in existing or future product lines, our ability to meet demandmultiple tax jurisdictions globally and our corresponding ability to sell affected products may be materially reduced. Moreover, our failure to timely deliver desirable products to meet demand may harm relationships with our 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 price fluctuations for 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 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 include GN, Sennheiser Communications, and VXI. For our Consumer products, our primary competitors include Sennheiser, 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.
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, 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.
In the markets for our Consumer products, which consist primarily of Bluetooth headsets, gaming, entertainment and computer audio headsets, we face many significant manufacturing, marketing and operational risks and uncertainties. The risks include the following:
The global market for mono Bluetooth headsets shrunk significantly in 2015, which was 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 than stereo market and thus far we have been unable to sufficiently increase share in the stereo market to offset decreases in the mono Bluetooth market and although we expect stereo Bluetooth 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.
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.

Competition in the consumer business market is intense and failure to compete successfully in these 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.

In May 2015 we issued $500.0 million of 5.50% 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 adversely 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 liens or enter into certain types of transactions such as sale and lease-back transactions; and
Limiting our ability to borrow additional funds or to borrow funds at rates or on other terms we find acceptable.

Periodically, we have drawn funds under our existing credit facilities in connection with our corporate return of capital policy and for other purposes. Amounts drawn under our outstanding credit agreement are subject to interest charges. Moreover, the credit agreement contains affirmative and negative covenants with which we must 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, if we borrow additional funds under the credit agreement, we may be required to increase the borrowing limit under the credit 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, someShould there be changes in foreign tax laws that seek to impose withholding taxes on the repatriation 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 lowercash or increase foreign tax rates the applicable tax laws were rescinded or changed, or the mix of ouron overseas earnings shifts from lower rate jurisdictions to higher rate jurisdictions, our operating results could be materially adversely affected. Furthermore, 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. 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 willChanges in applicable tax regulations and resolutions of tax disputes could negatively affect our financial results.

We are subject to taxation in the U.S. and numerous foreign jurisdictions. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The changes included in the Tax Act are broad and complex. As rule making bodies and new legislation is enacted to interpret the Tax Act, these changes may adjust the estimates provided in this report. The changes may possibly be materially adversely affected if we are unablematerial, due to, develop, manufacture,among other things, the Treasury Department’s promulgation of regulations and market new productsguidance that interpret the Tax Act, corrective technical legislative amendments that may change the Tax Act, any changes in accounting standards for income taxes or related interpretations in response to changing customer requirementsthe Tax Act, or any updates or changes to estimates the company has utilized to calculate the transition impacts, including impacts from changes to current year earnings estimates and new technologies.foreign exchange rates of foreign subsidiaries.
The technology used in our products
In addition, it is evolving more rapidly now than inuncertain how each country where we do business may react to 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.
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, resulting 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.Tax Act. Moreover, the increasingevolving global tax landscape accompanying the adoption of wireless headsets has also resulted in increased development costsand guidance associated with the introductionBase Erosion and Profit Shifting reporting requirements (“BEPS") recommended by the G8, G20 and Organization for Economic Cooperation and Development ("OECD") may require us to make adjustments to our financial results. As these and other tax laws and related regulations change, our financial results could be materially impacted. Given the unpredictability of these possible changes, it is difficult to assess whether the overall effect of these potential tax changes would be positive or negative for our earnings and cash flow, but such changes could adversely impact our financial results.

Our new wireless standards and more frequent changesevolving service offerings are strategically important to our future growth and profitability and our business may be harmed or our revenues and profitability materially hurt if we fail to successfully bring new offerings to market.

Our future growth and profitability are tied to our ability to successfully bring to market new and innovative services offerings like Habitat Soundscaping which we offer as a subscription service. We are investing significant time, resources and money into our services offerings with no expectation that they will provide material revenue in those standardsthe near term and capabilitieswithout any assurance they will succeed. Moreover, we expect that as comparedwe continue to wired technologies. If salesexplore, develop and margins onrefine new offerings they will continue to evolve, may not generate sufficient interest by end customers, may create channel conflicts with our traditional corded products declineexisting hardware distribution partners, and we aremay be unable to successfully design, develop, and market alternatives at historically comparable margins,compete effectively, generate significant revenues or achieve or maintain acceptable levels of profitability.

Additionally, our revenue and profits may decrease.
In addition, innovative technologies such as UC have moved the platformexperience with cloud services offerings is limited. We are also substantively reliant on third party service providers for certainsignificant aspects of our products fromofferings and over whom we have little or no market power regarding pricing, support,

service levels and compliance. If we do not successfully execute our customers' closed proprietary systems to open platforms such ascloud strategy or anticipate the PC, smartphones and tablets. In turn, these devices have become more openneeds of our customers, our credibility as a result of technologies such as cloud computingservices provider could be questioned and trends toward more open source software code development. As a result, the risk that currentour prospects for future revenue growth 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:profitability may never materialize.

Anticipate technology and market trends
Develop innovative new products and enhancements on a timely basis
DistinguishMoreover, if our products from those of our competitors
Create industrial designs that appeal to our customers and end-users

IfAccordingly, if we are unablefail to develop, manufacture, market,successfully launch, manage and introduce enhanced ormaintain our new products in a timely manner in response to changing market conditions or customer requirements, including changing fashion trends and styles,evolving services offerings future revenue growth and profitability may be limited and our business financial condition, and results of operations will be materially adversely affected.significantly harmed.

We have significant foreign manufacturing operationsa number of large customers with substantial market power whose ability to demand pricing and rely on third party manufacturers located outside the U.S.,promotion concessions as well as other unfavorable terms makes sales forecasting difficult and a significant amount ofharms 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 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 industriesprofitability.

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 countries 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, our customers may not recommend, de-emphasize, or discontinue carrying our products. Moreover, our OEMs may elect to manufacture their own products similar to 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. In turn, our traditional resellers may demand lower selling prices from 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.
Our customer mix is changing, and certain retailers, OEMs, and wireless carriers are more significant.significant than other customers.  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 haveare quite large with substantial buying power or who have strategic importance to our product marketing objectives. Many use their buying power or strategic importance to mandate onerous terms and conditions in ourto conduct business arrangements with them including unfavorable payment terms, fees and penalties for early, late and inaccurate shipments,shipping fees and penalties, 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,Cyber attacks on our networks, actual or perceived security vulnerabilities in our products and services, physical intrusion into our facilities, and loss of critical data and proprietary information could have a material adverse impact on our business and results of operations.
In the current environment, there are numerous and evolving security risks including cybersecurity and privacy, criminal hackers, state-sponsored intrusions, industrial espionage, employee malfeasance, and human or technological error. Computer hackers and others routinely attempt to breach the security of technology products, services, and systems such as ours, and those of customers, partners, third-parties’ contractors and vendors, and some of those attempts may be successful. We are not immune to these types of intrusions. 
Our products, services, network systems, and servers may store, process or transmit proprietary information and sensitive or confidential data, including valuable intellectual property and personal information, of ours and of our employees, customers, partners and other third parties. Our customers rely on our technologies for the secure transmission of such sensitive and confidential information in the conduct of their business. We are also subject to existing and proposed laws and regulations, as well as government policies and practices, related to cybersecurity, privacy and data protection worldwide.
Although we take physical and cybersecurity seriously and devote significant resources and deploy protective network security tools and devices, data encryption and other security measures to prevent unwanted intrusions and to protect our systems, products and data, we have and will continue to experience attacks of varying degrees in the conduct of our business. Cyber attackers tend to target the most popular products, services and technology companies, which can include our products, services or networks. As a result, our network is subject to unauthorized access, viruses, embedded malware and other malicious software programs.  In addition, outside parties may attempt to fraudulently induce employees or customers to disclose information in order to providegain access to our employee, vendor or customer data. Unauthorized access our network, data or systems could result in disclosure, modification, misuse, loss, or destruction of company, employee, customer, or other third party data or systems, the theft of sensitive or confidential data including intellectual property and business and personal information, system disruptions, access to our financial reporting systems, operational interruptions, product or shipment disruptions or delays, and delays in or cessation of the services we offer.
Any breaches or unauthorized access could ultimately result in significant legal and financial exposure, litigation, regulatory and enforcement action, and loss of valuable company intellectual property.  Affected parties or government authorities could initiate legal or regulatory actions against us in connection with greater insight intoany security breaches or improper disclosure of data, which could cause us to incur significant expense and liability or result in orders or consent decrees forcing us to modify our business practices.  Such breaches could also cause damage to our reputation, impact the characteristicsmarket’s perception of us and motivationsof the products and services that we offer, and cause an overall loss of confidence in the security of our distribution channelsproducts and services, resulting in a potentially material adverse effect on our business, revenues and results of operations, as well as customer attrition.

In addition, the cost and operational consequences of investigating, remediating, eliminating and putting in place additional information technology tools and devices designed to prevent actual or perceived security breaches, as well as the needscosts to comply with any notification obligations resulting from such a breach, could be significant and impact margins. Further, due to the growing sophistication of our end customers,the techniques used to better incentivize our sales partners and promoteobtain unauthorized access to or to sabotage networks, systems, or our products, which change frequently and often are not detected immediately by existing antivirus and other detection tools, we may be unable to end customers,anticipate these techniques or to implement adequate preventative measures. We can make no assurance that we have begun regional implementation of an authorization program as well as a back end rebate program. Under the authorization program, distributorswill be able to detect, prevent, timely and resellers are asked to enter into agreementsadequately address or supplement existing agreements in connection with the sale of allmitigate such cyber attacks or a portion of our products. The back end rebate program ties payment of post-sale discounts to distributor program compliance obligations. These programs are new and our partners may deem them difficult, time-consuming or disruptive, or the terms of the programs or our agreements unacceptable.security breaches.
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 policyOther risks that may result from interruptions to our business due to cyber attacks are discussed in lost salesthe risk factor entitled “Business interruptions could adversely affect our operations.”

Regulation and unauthorized disclosure of customer, end-user, business partner and employee data could materially harm our business relationships and reputation, potentially materially,subject us to significant reputational, legal and operational liabilities.

We are subject to an innumerable and ever-increasing number of global laws relating to the collection, use, retention, security, and transfer of personally information about our customers, end-users of our products, business partners and employees globally. Data protection laws may be interpreted and applied inconsistently from country to country and often impose requirements that are inconsistent with one another. In many cases, these laws apply not only to third-party transactions, but also to transfers of information internally and by and between us and other parties with whom we have commercial relations. These laws continue to develop in ways we cannot predict and may materially increase our cost of doing business, particularly as we expand the nature and types of products and services we offer including, without limitation, our software-as-a-service and Soundscaping subscription services.

Regulatory scrutiny of privacy, data protection, use of data and data collection is increasing on a global basis. Complying with these varying requirements could cause us to incur substantial costs or require us to change our business practices in a manner adverse to our business and violations of privacy-related laws can result in significant damages, fines and penalties.  For instance, in Europe, the General Data Protection Regulation (“GDPR”) was adopted in 2016 and became fully effective on May 25, 2018 and the California Consumer Privacy Act was enacted on June 28, 2018.

Privacy laws may affect our ability to reach current and prospective customers, to respond to both enterprise and individual customer requests under the laws (such as individual rights of access, correction, and deletion of their personal information), and to implement our business models cost effectively.

Complying with privacy laws, regulations, or other obligations relating to privacy, data protection, or information security have caused and will continue to cause us to incur substantial operational costs and may require us to periodically modify our data handling practices. Moreover, compliance may impact demand for our offerings and force us to bear the burden of more customersonerous obligations in our contracts. Non-compliance could result in proceedings against us by governmental entities or resellers.
If the numberothers, could result in substantial fines or other liability, and quality of our distributors and resellers declines,may otherwise adversely impact our business, financial condition and operating results.

In addition, compliance with these laws may restrict our ability to provide services our customers, business partners and employees find valuable. A determination that there have been violations of privacy laws relating to our practices could expose us to significant damage awards, fines and other penalties that could, individually or in the aggregate, materially harm our business and subject us to reputational, legal and operational liabilities.

We post on our websites our privacy policies and practices concerning the collection, use and disclosure of personal data. Any failure, or perceived failure, by us to comply with our posted policies or with any regulatory requirements or orders or other domestic or international privacy or consumer protection-related laws and regulations could result in proceedings or actions against us by governmental entities or others (e.g., class action litigation), subject us to significant penalties and negative publicity, require us to change our business practices, increase our costs and adversely affect our business. Data collection, privacy and security have become the subject of increasing public concern. If customers or end users were to reduce their use of our products and services as a result of these concerns, our business could be harmed. As noted above, we are also subject to the possibility of security breaches, which themselves may result in a violation of these laws.

Delays or loss of government contracts or failure to obtain or maintain required government certifications could have a material adverse effect on our business.
We sell our products indirectly and provide services to governmental entities in accordance with certain regulated contractual arrangements. While reporting and compliance with government contracts is both our responsibility and the responsibility of our partner, a lack of reporting or compliance by us or our partners could have an impact on the sales of our products to government agencies. Further, the United States Federal government has certain certification and product requirements for products sold to them. For instance, the United States Federal government remains focused on risks specific to products and applications designed, developed, or manufactured in other countries and the potential for security vulnerabilities to be inadvertently or intentionally

embedded in such products and applications. If we are unable to meet or maintain applicable certification or other requirements specified by the United States Federal government or to do so within the timeframes required, or if our competitors have certifications for competitive products for which we are not yet certified, our revenues and results of operations couldwould be materially, adversely affected.impacted.

The increased use of software in our products 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 and developing Internet based software-as-a-service offerings that provide additional value that complements our headsets.products. 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.two. 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,periods, 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 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 that may be issued may be invalidated, circumvented, or challenged by others. If we are required to enforce our intellectual property 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, existing patents, copyright registrations, trademarks, trade secrets and domain names may not provide competitive advantages or be adequate to safeguard and maintain our 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 entitiesthird parties 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 that is incorporated in the materials or components provided by one or more suppliers. As we have grown, intellectual property rights claims against us and our suppliers have increased along withincreased. There has also been a general trend of increasing intellectual property infringement claims against all corporations.corporations that make and sell products. 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,Many of our agreements with our distributors and resellers require us to indemnify them for certain third-party intellectual property infringement claims. 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. 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 existing and new 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. Certainstandards and 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. For instance, in the U.S. the 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, new regulations are enacted, and competition increases, we may need to modify our products to address those changes. Regulatory restrictions and competition may increasechanges, increasing the costs to design, manufacture, and sell our products, resulting in a decrease inand thereby decreasing our margins or a decrease in demand for our products if we attempt to pass along the costs. Regulations may also negatively adversely affect our ability to procure or manufacture raw materials and components necessary for our products. 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 transfer products into unauthorized jurisdictions or our products interfere with the proper operation of other devices, we or consumersend users 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, requirements regarding our use of certain minerals, known as conflict minerals, in our products and the suppliers who provide those minerals, particularly from and around the Democratic Republic of Congo, could 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.

We are regularly subject to a wide variety of litigation including commercial and employment 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 claims, labor and employment claims, and commercial matters.disputes. The number and significance of these claimsdisputes and disputesinquiries have increased as our company haswe have 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 product liability claims, including those alleging hearing 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. Likewise, research could establish a link between radio frequency emissions and corded or wireless headsets or we could become a party to litigation claiming such a link. There is also continuing public controversy over the use of mobile phones by operators of motor 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. Efforts to consolidate operations subsequent to the acquisitions such as our acquisition of Polycom in July 2018 through reductions in force, rationalization of sales channels, and vendor and supplier reductions increase the likelihood of litigation and the diversion of management time and energy. 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(Commitments and Contingencies"Contingencies) of this Annual Report on Form 10-K. Should GN's appeal be successful, in whole or in part, we could be required to incur additional litigation fees and expenses, be subject to material damages and penalties and management's attention could be diverted, all of which could materially harm our results of operations.

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.judgment. 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 and other forms of 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. Consequently, 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, motivate and retain 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, whether or not anticipated, 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, motivate and retain highly skilled technical, management, sales, and marketing personnel. Competition for such personnel is intense. Weintense and the salary, benefits and other costs to employ the right personnel may make it difficult to achieve our financial goals. Consequently, we may not be successful in attracting, motivating 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.processes or the recycling of all or a portion of the components of our products. 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 usemeet such environmental laws. Although our management systems are designed to maintain compliance, we cannot

assure you that we have been or will be at all times in complete compliance with such laws and disposalregulations. If we violate or fail to comply with any of our products.them, a range of consequences could result, including fines, import/export restrictions, sales limitations, criminal and civil liabilities or other sanctions. To the extent any new or modified policies, processes or procedures are difficult, time-consuming or costly to implement orimplement. we may incur claims for environmental matters exceeding reserves or insurance for environmental liability, our operating results could be negatively impacted.impacted
We have $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
Business interruptions could adversely affect our financial results.
As a result of past acquisitions we have $15.8 million of goodwill and other intangible assets on our consolidated balance sheet as of March 31, 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.operations.

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.  
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.

In the case of our managed services business, any circuit failure or downtime could affect a significant portion of our customers. Since our ability to attract and retain customers depends on our ability to provide customers with highly reliable service, even minor interruptions could harm our reputation, require that we incur additional expense to acquire alternative telecommunications capacity, or cause us to miss contractual obligations, which could have a material adverse effect on our operating results and our business.

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.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 Boardboard of Directorsdirectors 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.

Our largest stockholder has the means to influence our business and operations, its interests may differ from those of our other stockholders, and sales by that shareholder into the market could impact the price of our common stock.

As a consequence of our acquisition of Polycom, we issued approximately 6.352 million shares of our common stock to Triangle Private Holdings II, LLC ("Triangle"), an entity indirectly controlled by Siris Capital Group, LLC ("Siris"), equivalent to approximately 16% of our issued and outstanding shares, which has and will continue to dilute our earnings per share and has made Triangle our largest single stockholder.  In addition, we entered into a Stockholder Agreement with Triangle pursuant to which we appointed two individuals selected by Triangle to our board of directors.

The interests of Triangle, Siris and its other affiliated entities and individuals may differ from the interests of other holders of our common stock. Siris also holds, or in the future may hold, interests in other companies, that may compete with us, and the director representatives of Triangle are generally not required to present to us corporate opportunities such as potential acquisitions or new clients.

Triangle will be permitted to sell up to one-third of our shares issued pursuant to the acquisition on July 2, 2019, up to two-thirds of their shares beginning on January 2, 2020 and all of the shares after July 2, 2020.  The average daily trading volume of our stock is limited, and any resale of the shares held by Triangle will increase the number of shares of our common stock available for public trading, which may depress the price of our stock.  Additionally, the sale by Triangle or their successors of all or a substantial portion of the shares in the public market, or the perception that such sales may occur, could impact the price of our common stock.

We cannot guarantee we will continue to repurchase our common stock pursuant to stock repurchase programs or that we will pay dividends 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.

We have a history of recurring stock repurchase programs and payment of quarterly dividends. Any determination to continue 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. Furthermore, while any debt repayment obligations remain outstanding in connection with the Credit Agreement our ability to return capital to stockholders through stock repurchases, dividend declarations or otherwise may be limited in whole or in part.

Additionally, any future stock repurchases and dividend declarations may require us to draw against available funds under the Credit Agreement or incur additional indebtedness, any of which may obligate us to pay interest, require payment of other expenses, and may not be available to us or available on terms we deem acceptable. 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.

Our business could be negatively affected as a result of stockholder activism, and such stockholder activism could impact the trading price and volatility of our common stock.
We may be the target of strategic or competitive buyers, private equity investors and activist stockholders from time to time. Responding to actions by a potential buyers, investors and activist stockholders, such as public proposals and requests for special meetings, potential nominations of candidates for election to our board of directors, requests to pursue a strategic combination or other transaction, or other special requests, can be costly and time-consuming, disrupt our operations and divert the attention of management and our employees. Additionally, perceived uncertainties as to our future direction or changes to the composition of our board may be exploited by our competitors, cause concern to our current or potential customers and partners and make it more difficult to attract and retain qualified personnel. Such uncertainties may adversely impact our business and future financial results. In addition, our stock price may experience periods of increased volatility as a result of stockholder activism.

Our stock price could become more volatile and your investment could lose value.

All of the factors discussed in this section could affect our stock price. The timing of announcements in the public market regarding new products, product enhancements or technological advances by our competitors or us and any announcements by us of acquisitions, major transactions, or management changes could also affect our stock price. Our stock price is subject to speculation by analysts and in the press, changes in recommendations or earnings estimates by financial analysts, changes in investors’ or analysts’ valuation measures for our stock, changes in or announcements regarding our forecasts and guidance, our credit ratings, market trends unrelated to our performance, and sales of our common stock by us, our officers or directors or unaffiliated third party investors, particularly considering the concentrated ownership of our common stock, that may limit the ability for investors to acquire or sell meaningful quantities of our stock or cause speculation as to the acquisition or sale of our stock. A significant drop in our stock price could also expose us to the risk of securities class action lawsuits, which could result in substantial costs and divert management’s attention and resources, which could adversely affect our business.

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, weWe are presently engaged in various legal actions arising in the normal course of business. We believe that 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. For additional information about our material legal proceedings, please see Note 9, Commitments and Contingencies, of the accompanying notes to the consolidated financial statements.

As of May 12, 2016,14, 2019, there were approximately 4839 holders of record of our common stock.  Because many of our shares of common stock are held by brokers and other institutions on behalf of beneficial owners, we are unable to estimate the total number of beneficial owners, but we believe it is significantly higher than the number of record holders.  On April 1, 2016,

Total Net Revenues (in millions)
chart-1bb74c2b2d264e8a769.jpg

Compared to the prior year, net revenues decreased 0.9%increased 95.4% to $856.9 million.$1.7 billion. The decreaseincrease in net revenues was driven by lower revenues within our Consumer product category, which declined 6.3% fromprimarily related to the prior year. This decline was partially offset by slight growthAcquisition. As a result of purchase accounting, a total of $84.8 million of deferred revenue that otherwise would have been recognized in our Enterprise product category, which increased 1.2% from the prior year. While our primary driver of revenue growth continues to be revenues from the sale of our UC products, our fiscal year 2016 Consumer revenues were negatively impacted by $22 million due 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") decreased2019 was excluded from annual net revenues of approximately $1.7 billion.

Operating Income (Loss) (in our fiscal year 2016 compared to the prior year.millions)
chart-129e81df03215063cd0.jpg

Operating profit decreased 27.5%(188.5)% from the prior year to $108.0$(109.3) million due primarily to restructuring charges taken during fiscal year 2016, the fluctuations in foreign currency exchange rates, and the impactor (6.5)% 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 operatingdriven primarily by $160.2 million of amortization of purchased intangibles, $68.7 million of acquisition and integration expenses, although to a lesser degree, for a net unfavorable impact of $11and $30.4 million to our operating profit. These items were partially offset by a reduction in variable compensation expense due to lower profitability. We delivered $68.4 million in net income, representing approximately 8.0% of our net revenues.inventory fair value adjustment.

We generate approximately 40% to 45%Our strategic initiatives are primarily focused on driving long-term growth through our end-to-end portfolio of our revenues from international sales; therefore,audio and video endpoints, including headsets, desktop phones, conference room phones, and video collaboration solutions. The acquisition positions us well as a global leader in communications and collaboration endpoints and by targeting the impact of currency movements on our 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 businessfaster-growing market segments, such as the stronger dollar negatively impacts buying decisions. Unfavorable impacts fromHuddle Room segment for video collaboration, we believe will drive long-term revenue growth.

Within the global economymarket for our Enterprise Headsets, we anticipate the key driver of growth over the next few years will be the continued adoption of UC&C solutions. We believe enterprises are increasing their adoption of UC&C systems to reduce costs, improve collaboration, and consumer spending together with exchange rate fluctuations could continuemigrate to negatively impact our net revenuesmore capable and flexible technology. We expect the growth of UC&C solutions will increase overall headset adoption in enterprise environments, and we believe most of the growth in our fiscal year 2017. We continually work to offset currency movements through hedging strategiesEnterprise Headsets product category over the next three years will come from headsets 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 hedging conducted a year ago is expected to deliver little benefit to offset the stronger dollar against other major currencies in fiscal year 2017.for UC&C.

Revenues from our Consumer products channelHeadsets are seasonal and typically strongest in our third fiscal quarter, which includes the majority of the holiday shopping season. Additionally, otherOther factors that directly impact our Consumerperformance in the product category performance, such as consumer preferences, changes in consumer confidence and other macroeconomic factors,include product life-cycleslife cycles (including the introduction and pace of adoption of new technology), market acceptance of new product introductions, consumer preferences and the competitive retail environment. Our Consumer business continues to be impacted by a declineenvironment, changes in sales volumes in our mono Bluetooth products as the market for these products contracts. The unit volumes in our stereo Bluetooth category increased slightly when compared to the prior fiscal year, driven primarily by our newer generation of products. We anticipate that these newer productsconsumer confidence and other planned investments in the Consumer category will allow us to better compete in these consumer product categories as they continue to expand. While we have been building our stereo portfolio over the last several years, it is not yet as robust as our mono Bluetooth portfolio of products. As a result of these 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 long-term brand position.


Due to slower than anticipated growth of UC revenues, combined with the negative 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 make 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, 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 2017, UC continues 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 most of the growth in our Enterprise product category over the next five years to come from headsets designed for UC.

macroeconomic factors. In addition, the timing or non-recurrence of retailer product placements can cause volatility 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.quarter-to-quarter results.


We remain cautious about the macroeconomic environment, based on uncertainty around trade and fiscal policy in the U.S., as well as and broader economic uncertainty in many parts of Europe and Asia Pacific, which makes it difficult for us to gauge what impact the economy may haveeconomic impacts on our future business, and the fact that the UC opportunity has not matured as quickly as we initially anticipated.business. We will continue to monitor our expenditures and prioritize expenditures that further our strategic long-term growth opportunities such as innovative product development in our core research and development 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 investing in key strategic alliances and integrations with major UC vendors.opportunities.

revenues increased in Fiscal Year 2019 compared to the prior fiscal year primarily due to the Acquisition as well as higher revenues within both our Enterprise Headset and Consumer Headset product categories. The growth in our Enterprise Headset category was driven by UC&C product revenues while the growth in our Consumer Headset category was driven by Gaming and Stereo product revenues. The impact to net revenues resulting from changes in foreign exchange rates was not material in Fiscal Year 2019.

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 2018 compared to the prior fiscal year 2016 comparedprimarily due to fiscal year 2015 due largely to a decline inlower revenues within our Consumer revenues,Headsets product category which was mainly attributable to the shrinking mono Bluetooth market. This decline was partially offset by slight growthincreases in our Enterprise Headsets product revenues driven by UC&C revenues. Fiscal Year 2018 net revenues were also favorably impacted by fluctuations in exchange rates which resulted in an increase of approximately $9 million in demand for UC products resulting from continued adoptionnet revenues (net of UC voice solutions in the marketplace, partially offseteffects of hedging).

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.millions)
chart-2c65920ac37f5131bee.jpg

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 was awaiting a refresh which began in fiscal year 2016. A stronger U.S. Dollar ("USD") compared to the other foreign currencies in which we sell decreased net revenues by approximately $5 million, net of the effects of hedging, in fiscal year 2015 compared to fiscal year 2014.

As a percentage of total net revenues, U.S. net revenues decreased slightly compared with internationalin Fiscal Year 2018 from Fiscal Year 2017 due to a decline in sales of our Consumer Headset and Core Enterprise Headset products which were partially offset by increased sales of our UC&C products. International net revenues infor Fiscal Year 2018 increased from the prior fiscal year 2015 compared to fiscal year 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 forincreased sales of our 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 due primarily to increased Enterprise net revenues reflecting continued growth in demand for UC&C products and to a lesser extent, higher Consumer revenues.

Compared to the prior fiscal year, gross profit as a percentage of net revenues decreased in fiscal year 20162019, due primarily to $114.4 million of amortization of purchased intangibles, $84.8 million of deferred revenue fair value adjustment, and $30.4 million of amortization of the weakeninginventory step-up associated with the Acquisition; refer to Note 4, Acquisition. Other unfavorable items were cost increases on commodity components driven by industry capacity shortages and a product mix with higher gaming and stereo revenues within our Consumer Headsets product category, which carries lower margins. These increased costs were partially offset by reductions in the cost of materials.

Compared to Fiscal Year 2017, gross profit as a percentage of net revenues increased in Fiscal Year 2018 primarily due to product cost reductions, the strengthening of foreign currencies relative to the USD,US Dollar which negativelyfavorably impacted margins on our international product sales. Gross profit was further negatively impacted bysales, and 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 shift away from Enterprise to Consumer; (ii) within Enterprise, the continued ramp in UC,our Consumer product category 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. margins.

There are significant variances in gross profit percentages between our higher and lower margin products;products including Polycom products resulting from the Acquisition; therefore, small variations in product mix, which can be difficult to predict, can have a significant impact on gross profit.profit as a percentage of net revenues.  Gross profit percentages 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.expenses.

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 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 2015Fiscal Year 2019 compared to fiscal year 2014Fiscal Year 2018 was primarily due to the inclusion of Polycom operating expenses, $67.4 million of Acquisition and Integration related costs, and $45.8 million of amortization of purchased intangibles incurred during the period. Refer to Note 4, Acquisition of the accompanying Notes to the Consolidated Financial Statements.

The increase in selling, general, and administrative expenses in Fiscal Year 2018 compared to Fiscal Year 2017 was due primarily to $13.5 millionthe recognition of third-party fees related to the Polycom Transaction and increases in higher headcount-related costs resulting from higher performance-basedlegal fees related to our litigation with GN Netcom. These increases were partially offset by lower 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 and $7.1 million in higher legal expenses driven mainly by ongoing litigation.

Gain from Litigation Settlements

During the fiscal year ended March 31, 2016 wereduced funding of our variable compensation plans, executive transition costs 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 usin prior period as well as miscellaneous immaterial settlementscost savings from cost control initiatives and prior period restructuring actions. For more information on the litigation with other parties.GN Netcom, refer to Note 9, Commitments and Contingencies, of the accompanying Notes to the Consolidated Financial Statements.

During the fiscal year ended March 31, 2015Fiscal Year 2019, we incurred immaterial losses from litigation. During Fiscal Year 2018 we recognized immaterial gains of approximately $8.7from litigation. During Fiscal Year 2017 we recorded a $4.9 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 millioncharge related to discovery sanctions ordered by the resolutioncourt in the GN Netcom litigation. This charge was partially offset by immaterial gains from unrelated matters. For more information regarding on-going litigation, refer to Note 9, Commitments and Contingencies, of an insurance coverage dispute with one of our insurance carriers.

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-taxDuring Fiscal Year 2019 restructuring and other related 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 attributableincreased, due primarily to stock award forfeitures resulting fromrestructuring actions initiated during Fiscal Year 2019 subsequent to the Acquisition. For more information regarding restructuring action. Projected annual saving from this plan are in the range of approximately $15activities, refer 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 the accompanying Notes to the Consolidated Financial Statements.

During Fiscal Year 2018 restructuring and other related charges (credits) increased, due to additional restructuring actions taken during the first quarter of Fiscal Year 2018 as part of our ongoing efforts to reduce costs and focus on improving profitability. These restructuring actions included a reduction-in-workforce, charges to terminate a lease before the end of its contractual term and a loss on the sale of our Clarity division. For more information regarding these restructuring activities, refer to Note 11, Restructuring and other related charges (credits), of ourthe accompanying Notes to the Consolidated Financial StatementsStatements.


During Fiscal Year 2017 we recorded a net favorable adjustment resulting from changes to the estimates related to our restructuring actions recorded in this Form 10-K for further information onFiscal Year 2016. The favorable adjustment was partially offset by additional restructuring costs.charges of approximately $1.3 million related to an action in fourth quarter of Fiscal Year 2017. The restructuring action taken in the fourth quarter of fiscal year 2017, while immaterial to consolidated results, was initiated to reduce the cost of our design and manufacturing processes, specifically in our Consumer product lines, as part of a broader strategic effort to improve our cost structure and consolidated profitability in subsequent fiscal years.

The effective tax rate for fiscalFiscal 2019 was lower than that in the previous year 2016 is lowerdue to the prior year’s $79.7 million tax expense related to a one-time deemed repatriation of accumulated foreign subsidiary unremitted earnings (hereafter, the "toll charge") required by the Tax Cuts and Jobs Act (H.R. 1) ("the Tax Act"). In addition to the toll charge, the Tax Act includes several changes to the Internal Revenue Code, including, among other things, a permanent reduction in the corporate income tax rate from 35% to 21% and applying new taxes on certain foreign source earnings. The effective tax rate for Fiscal 2018 was higher than that in the previous year due primarily to domestic interest expense on new debt and tax benefits associatedthe toll charge.


During Fiscal 2019, we finalized our computation of the toll charge in accordance with Staff Accounting Bulletin SAB 118 (“SAB 118”), which addressed concerns about reporting entities’ ability to timely comply with the unwindrequirements to recognize the effects of prior cost-sharingthe Tax Act.  During Fiscal 2018, the Company recorded a provisional toll charge of stock based compensation$79.7 million. During Fiscal 2019, the toll charge computation was finalized resulting in a tax benefit of $0.8 million. During Fiscal 2018, the Company recorded a provisional expense of $5.0 million related to state income taxes and foreign withholding taxes for unrepatriated foreign earnings through the Tax Act’s enactment date. During Fiscal 2019, the computation of transitional state and foreign withholding taxes was completed resulting in the recognition of a tax benefit of $3.2 million. The effect of the SAB 118 measurement period adjustments to the effective tax rates for the engineering function. A retroactive and permanent reinstatement of the federal research credityear ended March 30, 2019 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.(2.1)%.

Our effective tax rate for fiscal years 2016, 2015,Fiscal 2017, 2018, and 20142019 differs from the statutory rate due to the impact of foreign operations taxed at different statutory rates, income tax credits, state taxes, the Tax Act, 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 $12.7 million of unrecognized tax benefits as of March 31, 2016 compared to $12.8 million and $12.6 million as of March 31, 2015 and 2014, respectively. The unrecognized tax benefits as of the end of fiscal year 2016 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, 2016, we had approximately $1.6 million of accrued interest related to uncertain tax positions, compared to $1.8 million and $1.7 million as of March 31, 2015 and 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.


The Company and its subsidiaries are subject to taxation in various foreign and state jurisdictions, including the U.S.  All federal tax matters have been concluded for tax 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 2015.

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

NetCompared to Fiscal Year 2018, net cash provided by operating activities during the year ended March 31, 2016Fiscal Year 2019 decreased primarily as a result of cash paid for acquisition and integration costs, restructuring activities, interest payments on long-term debt, and tax payments. The decrease was partially offset by higher cash collections from the prior year duecustomers as a result of increased revenue.

Compared to Fiscal Year 2017, net cash provided by operating activities during Fiscal Year 2018 decreased primarily toas a result of lower net income after adjusting for non-cash items - predominantlyand higher payouts in the remeasurementfirst quarter of our non-designated hedge instruments, stock-basedFiscal Year 2018 related to Fiscal Year 2017 variable 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.

Investing Activities
 
Net cash used for investing activities during the year ended March 31, 2016Fiscal Year 2019 increased from the prior fiscal year ended March 31, 2015primarily due to an increase in the net purchases of investments and an increase in capital expenditures.

Net cash used for investing activities duringAcquisition which closed on July 2, 2018. Refer to Note 4, Acquisition. This decrease was partially offset by the year ended March 31, 2015 decreasedproceeds from the year ended March 31, 2014 due to a decrease in capital expendituressales and an increase in the net cash received from salesmaturities 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.


We anticipate our capital expenditures in fiscal year 2017 toFiscal Year 2020 will be approximately $25.0$40 million to $30.0$50 million, relatedpertaining 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 2017 consist primarily ofinformation technology ("IT") investments, capital investment in our manufacturing capabilities, including tooling for new products. products, and facilities upgrades.


Net cash used for investing activities during Fiscal Year 2018 decreased from the prior fiscal year due to an increase in proceeds from the sales and maturities of debt securities, net of new investment purchases. This increase was partially offset by lower capital expenditures.

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 forprovided by financing activities during the year ended March 31, 2016 decreasedFiscal Year 2019 increased from the prior fiscal year ended March 31, 2015 primarily driven by netas a result of the proceeds received from issuance of the 5.50% Senior Notesterm loan facility which were partially offset by an increase in the levelrepayment of long-term debt, dividend payments, and repurchases of common stock repurchases.during the fiscal year.

Net cash used for financing activities during the year ended March 31, 2015Fiscal Year 2018 increased from the prior fiscal year ended March 31, 2014primarily due to an increase in the level ofcash used for common stock repurchases and an increase in our quarterly dividend beginning in the first quarter of our fiscal year 2015. These items weredriven by a lower average stock price which was partially offset by an increase inhigher net proceeds from our revolving line of credit.

On 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, 2016 to stockholders of record at the close of business on May 20, 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.stock-based compensation plans.

Liquidity and Capital Resources
 
Our primary discretionary cash uses have historically been for repurchasessources of our common stock and dividend payments.  At liquidity as of March 31, 2016,2019, consisted of cash, cash equivalents, and short-term investments, cash we expect to generate from operations, and a $100 million revolving credit facility.  At March 31, 2019, we had working capital of $487.8$252.9 million,, including $395.3$215.8 million of cash, cash equivalents, and short-term investments, compared to working capital of $507.8$774.2 million,, including $374.7$660.0 million of cash, cash equivalents, and short-term investments at March 31, 2015.2018.  The decrease in working capital at March 31, 20162019 compared to March 31, 2015 results2018 resulted from the decrease in accounts receivable and increase in accounts payable both due primarily to improved working capital management.impact of the Acquisition during the fiscal year.

Our cash and cash equivalents as of March 31, 20162019 consist of bank deposits with third party financial institutions, Commercial Paper, and Corporate Bonds.  We monitor bank balances in our operating accounts and adjust the balances as appropriate.institutions.  Cash balances are held throughout the world, including substantial amounts held outside of the U.S.  As of March 31, 2016,2019, of our $395.3$215.8 million of cash, cash equivalents, and short-term investments, $40.9$66.4 million iswas held domestically while $354.4$149.5 million iswas held by foreign subsidiaries, and approximately 90% of which were69% was based in U.S. dollar-denominated holdings.

During the quarter ended June 30, 2018, we sold most of our short-term investments 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 themgenerate cash used 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.the Acquisition which was finalized on July 2, 2018. As of March 31, 2016,2019, our remaining investments arewere composed of Mutual Funds, US Treasury Notes, Government Agency Securities, Commercial Paper, Corporate Bonds,Funds.

On July 2, 2018, we completed the acquisition of all of the issued and Certificatesoutstanding shares of Deposits ("CDs"capital stock of Polycom. The Acquisition was consummated in accordance with the terms and conditions of the previously announced Purchase Agreement, dated March 28, 2018, among the Company, Triangle and Polycom. At the closing of the Acquisition, Plantronics acquired Polycom for approximately $2.2 billion with the total consideration consisting of (1) 6.4 million shares of our common stock (the "Stock Consideration"), resulting in Triangle, which was Polycom’s sole shareholder, owning approximately 16.0% of Plantronics following the acquisition and (2) $1.7 billion in cash (the "Cash Consideration"). The consideration paid at closing was also subject to working capital, tax and other adjustments. We financed the Cash Consideration by using available cash-on-hand and funds drawn from our new term loan facility which is described further below. Portions of the Stock Consideration and the Cash Consideration were each deposited into separate escrow accounts to secure certain indemnification obligations of Triangle pursuant to the Purchase Agreement.

In connection with the Acquisition, we entered into a Credit Agreement with Wells Fargo Bank, National Association, as administrative agent, and the lenders party thereto (the “Credit Agreement”). The Credit Agreement replaced the Company’s prior revolving credit facility in its entirety. The Credit Agreement provides for (i) a revolving credit facility with an initial maximum aggregate amount available of $100 million that matures in July 2023 and (ii) a $1.275 billion term loan facility due in quarterly principal installments commencing the last business day of March, June, September and December beginning with the first full fiscal quarter ending after the closing date for the aggregate principal amount funded on the Closing Date multiplied by 0.25% (subject to prepayments outlined in the Credit Agreement) and all remaining outstanding principal due at maturity in July 2025. On July 2, 2018, the Company borrowed the full amount available under the term loan facility of $1.245 billion, net of approximately $30 million of discounts and issuance costs. Proceeds from the initial borrowing under the Credit Agreement were used to finance the acquisition of Polycom, to refinance certain debt of Polycom, to pay related fees, commissions and transaction costs. We have additional borrowing capacity under the Credit Agreement through the revolving credit facility which could be used to provide ongoing working capital and capital for other general corporate purposes of us and our subsidiaries. Our obligations under the Credit Agreement are currently guaranteed by Polycom and will from time to time be guaranteed by, subject to certain exceptions, any domestic subsidiaries that may become material in the future. As of March 31, 2019, the Company has four outstanding letters

of credit on the revolving credit facility for a total of $0.8 million and the Company is in compliance with all covenants. In Fiscal Year 2019, we prepaid $100 million of our outstanding principal on the term loan facility. For additional details, refer to Note 10, Debt, of the accompanying notes to consolidated financial statements.

On July 30, 2018, we entered into a 4-year amortizing interest rate swap agreement with Bank of America, NA. The swap has an initial notional amount of $831 million and matures on July 31, 2022. The purpose of this swap is to hedge against changes in cash flows (interest payments) attributable to fluctuations in the contractually specified LIBOR interest rate associated with our new credit facility agreement. The swap involves the receipt of floating-rate amounts for fixed interest rate payments over the life of the agreement. We have designated this interest rate swap as a cash flow hedge. The derivative is valued based on prevailing LIBOR rate curves on the date of measurement. We also evaluate counterparty credit risk when we calculate the fair value of the swap. For additional details, refer to Note 16, Derivatives, of the accompanying notes to condensed consolidated financial statements.

As of March 31, 2019, the Company has paid $21.5 million of the toll charge under the Tax Act and the remaining toll charge liability of $57.3 million will be paid over the next six years. The Company also paid a $6.9 million toll charge in October 2018 related to Polycom’s pre-acquisition toll charge. For additional details, refer to Note 17, Income Taxes, of the accompanying Notes to the Consolidated Financial Statements.

From time to time, our Board of Directors ("the Board") authorizes programs under which we may repurchase shares of our common stock depending on market conditions, in the open market or through privately negotiated transactions, including accelerated stock repurchase agreements. The following table summarizesOn November 28, 2018, the Board of Directors approved a 1 million shares repurchase program expanding our capacity to repurchase of common stock as part of these publicly announced repurchase programs as well as shares withheld in satisfaction of employee tax withholding obligations upon the vesting of restricted stock granted under our stock plans:

Refer to Note 12,13, 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 years 2016, 2015,Fiscal Years 2017, 2018 and 2014.2019.

In May 2015, we entered into an Amended and Restated Credit Agreement (the “Credit Agreement”) with Wells Fargo Bank, National Association (the “Bank”). The Credit Agreement amended and restated our prior credit agreement, dated as of May 2011. The Credit Agreement provides for a $100.0 million unsecured revolving credit facility to augment our financial flexibility. Our obligations underDuring the Credit Agreement are required to be guaranteed by the 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, 2016 the Company had no outstanding borrowings under the line of credit. 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:

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

In addition, we and our subsidiaries are required to maintain unrestricted cash, cash equivalents and marketable securities plus availability under the Amended Credit Agreement at the end of each fiscal quarter of at least $300.0 million. The Amended Credit Agreement contains customary events of default that include, among other things, payment defaults, covenant defaults, cross-defaults with certain other indebtedness, bankruptcy and insolvency defaults, and judgment defaults. The occurrence of an event of default could result in the acceleration of the obligations under the Amended Credit Agreement. As ofended March 31, 2016, we wereobtained $488.4 million from debt financing, net of issuance costs. The debt matures
on May 31, 2023 and bears interest at a rate of 5.50% per annum, payable semi-annually on May 15 and November 15 of each year. Refer to Note 8, Debt, in breach of our debt to EBITDA ratio covenant but in compliance with all other ratios and covenants by a substantial margin.

On May 2, 2016, we received a waiver from the lender for noncompliance with the minimum EBITDA covenant at March 31, 2016. Pursuantaccompanying Notes to the terms of 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.Consolidated Financial Statements.

Our liquidity, capital resources, and results of operations in any period could be affected by repurchases of our common stock, 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 ESPP.Employee Stock Purchase Plan ("ESPP"). We expect the Acquisition to affect our liquidity and leverage ratios and we plan to reduce our debt leverage ratios by prioritizing the repayment of the debt obtained to finance the Acquisition. The Acquisition impacted our cash conversion cycle due to Polycom's use of third-party partner financing and early payment discounts to drive down cash collection cycles. We are still assessing these changes as we integrate Polycom into our business. We receive cash from the exercise of outstanding stock options under our stock plan and the issuance of shares under our 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 will expire.

On May 7, 2019, we announced that our Audit Committee of the Board of Directors ("the Audit Committee") declared a $0.15 cash dividend per share of common stock, payable on June 10, 2019 to stockholders of record at the close of business on May 20, 2019. 

We 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 fund operations for at least the next 12 months; however, any projections of future financial needs and sources of working capital are subject to uncertainty.  Readers are cautioned to review the risks, uncertainties, and 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, 20162018, and 2015,2019, we had off-balance sheet consigned inventories of $41.1$48.8 million and $33.4$47.1 million, respectively.

Operating Leases

We lease certain facilities under operating leases expiring through our fiscal year 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 utilizeuse 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, 20162019, we had outstanding off-balance sheet third-party manufacturing, component purchase, and other general and administrative commitments of $399.0 million, including off-balance sheet consigned inventories of $47.1 million.

Operating Leases

We lease certain facilities under operating leases expiring through our Fiscal Year 2025. 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. ,In addition to the net minimum lease payments noted above, we are contractually obligated to pay certain operating expenses during the term of the lease such as maintenance, taxes and insurance. Included in the lease obligations acquired are Polycom’s sublease receipts, which have been netted against the gross lease payments above to arrive at our net minimum lease payments. Certain of these leases provide for renewal options and we may exercise the renewal options.

Unconditional Purchase Obligations

We use 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.

As of March 31, 2019, we had outstanding off-balance sheet third-party manufacturing commitments and component purchase commitments of $150.9$287.5 million,, all of which we expect to consume in the normal course of business.

Toll Charge


During the year ended March 31, 2018, our short and long-term tax obligations increased due to introduction of the Tax Act which required the payment of the toll charge. As permitted under the Tax Act, we expect to pay the toll charge obligation over an 8-year period. For additional details regarding the Tax Act and the toll charge, refer to Note 17, Income Taxes, in the accompanying Notes to the Consolidated Financial Statements.

Unrecognized Tax Benefits

As of March 31, 2016,2019, long-term income taxes payable reported on our consolidated balance sheet included unrecognized tax benefits and related interest of $12.7$25.1 million and $1.6$2.0 million, respectively.  We are unable to reliably estimate the timing of future payments related to unrecognized tax benefits andas such, 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 Notesnotes to Consolidated Financial Statementsconsolidated 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
 
Our revenue consists of hardware, software, and services. Revenue is recognized when control for these offerings is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for products and services.

Our contracts with customer may include promises to provide multiple deliverables. Determining whether the offerings and services are considered distinct performance obligations that should be accounted for separately or as one combined performance obligation may require significant judgment. Judgment is required to determine the level of integration and interdependency between certain professional services and the related hardware and software. This determination influences whether the services are distinct and accounted for separately as a performance obligation.

Service revenue primarily includes maintenance support on hardware devices and is recognized ratably over the contract term as those services are delivered. Product, software, and certain other services are satisfied at a point in time when control is transferred or as the services are delivered to the customer.

For contracts with more than one performance obligation, the transaction price is allocated among the performance obligations in an amount that depicts the relative standalone selling price ("SSP") of each obligation. Judgment is required to determine the SSP for each distinct performance obligation. We use a range of amounts to estimate SSP when we sell substantially alleach of ourthe products and services separately and need to end users through distributors, retailers,determine whether there is a discount that should be allocated based on the relative SSP of the various products and carriers. The Company recognizes revenue when persuasive evidenceservices. We typically have more than one SSP for individual products and services due to the stratification of an arrangement exists, delivery has occurred,those products and services by customer and circumstance. In these instances, we use relevant information such as the sales price is fixed or determinable,channel and collection is reasonable assured.geographic region to determine the SSP.

Our indirect channel model includes both a two-tiered distribution structure, where we sell to distributors that subsequently sell to resellers, and a one-tiered structure where we sell directly to resellers. For mostthese arrangements, transfer of the Company’s product sales, these criteria are metcontrol begins at either the time the productaccess to our services is shipped or themade available to our end customer has received the product. Commercialand entitlements have been contractually established, provided all other criteria for revenue recognition are met. Judgment is required to determine whether our distributors and retailers represent our largest sourcesresellers have the ability to honor their commitment to pay, regardless of net revenues. whether they collect payment from their customers. If we were to change this assessment, it could cause a material increase or decrease in the amount of revenue that we report in a particular period.

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 back end rebates, advertising,discounts, marketing development funds, 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 partner incentives are intended to drive hardware sell through and reduce revenue in the current period accordingly. Depending on how the payments are made, the reserves associated with the partner incentive programs are recorded on the balance sheet as either contra accounts receivable or accounts payable.

The primary factors affectingnew revenue recognition standard, which we adopted on April 1, 2018, had an immaterial impact in 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 usconsolidated financial statements. Refer 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, 2016 by a hypothetical 10%Note 2, Significant Accounting Policies, our sales returns reserve and sales incentive allowance would have increased by approximately $0.7 million and $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 $4.0 million and $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 andaccompanying Notes to the software deliverables as a group using the relative selling prices of each of the deliverablesConsolidated Financial Statements in the arrangement basedthis Annual Report 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, 2016 and 2015. As of March 31, 2016 and 2015, total deferred revenue related to the software portion of multiple-element arrangements was $2.7 million and $2.0 million, respectively.


Form 10-K.

Inventory Valuation

Inventories are valued at the lower of cost or market.net realizable value.  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, 20162019 by a hypothetical 10%, the reserves and cost of revenues would have each increased by approximately $0.4$2.9 million and our net income would have been reduced by approximately $0.4$2.3 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, 20162019 by a hypothetical 10%, our obligation and the associated cost of revenues would have each increased by approximately $0.9$1.0 million and our net income would have been reduced by approximately $0.6$0.7 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,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. 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 provision forOn December 22, 2017, the Tax Act was passed in the United States. The Tax Act includes several changes to existing tax law, including, among other things, a permanent reduction in the corporate income tax rate from 35% to 21% and applying new taxes does not include provisions for U.S.on certain foreign source earnings. In addition, we were subject to a one-time deemed repatriation of accumulated foreign subsidiary unremitted earnings (“toll charge”).

During the fiscal quarter ended December 31, 2018, the Company completed its computation of the tax act in accordance with Staff Accounting Bulletin SAB 118 (“SAB 118”), which addressed concerns about reporting entities’ ability to timely comply with the requirements to recognize the effects of the Tax Cuts and Jobs Act. During the fiscal year ended March 31, 2018, the Company recorded a provisional toll charge of $79.7 million, During fiscal year 2019, the toll charge was finalized resulting in a tax benefit of $0.8 million. The Company's has paid $21.5 million of the toll charge and the remaining toll charge liability of $57.3 million will be paid over the next six years. During the fiscal year ended March 31, 2018, the company recorded a provisional expense of $5.0 million related to state income taxes and foreign withholding taxes for unrepatriated foreign earnings through the Tax Act’s enactment date. During fiscal year 2019, the toll charge computation impact to state and foreign withholding taxes was completed resulting in the recognition of a tax benefit of $3.2 million. The effect of the SAB 118 measurement period adjustments to the effective tax rates for the year ended March 30, 2019 was (2.1)%, Polycom recorded a toll charge which was paid in October 2018 with the filing of its 2017 tax return. For additional details, refer to Note 17, Income Taxes, of the accompanying notes to condensed consolidated financial statements.

Business Acquisitions

Accounting for business acquisitions requires us to make significant estimates and assumptions, especially at the acquisition date with respect to tangible and intangible assets acquired and liabilities assumed and pre-acquisition contingencies. We use our best estimates and assumptions to accurately assign fair value to the tangible and intangible assets acquired and liabilities assumed at the acquisition date. Liabilities assumed may include litigation and other contingency reserves existing at the time of acquisition and require judgment in ascertaining the related fair values. Independent appraisals may be used to assist in the determination of the fair value of certain assets and liabilities. Such appraisals are based on significant estimates provided by us, such as forecasted revenues or profits utilized in determining the fair value of contract-related acquired intangible assets or liabilities. Significant changes in assumptions and estimates subsequent to completing the allocation of the purchase price to the assets and liabilities acquired, as well as differences in actual and estimated results, could result in material impacts to our financial results. Adjustments to the fair value of contingent consideration are recorded in earnings. Additional information related to the acquisition date fair value of acquired assets and liabilities obtained during the allocation period, not to exceed one year, may result in changes to the recorded values of acquired assets and liabilities, resulting in an offsetting adjustment to the goodwill associated with the repatriationbusiness acquired.

Goodwill and Purchased Intangibles

Goodwill has been measured as the excess of undistributed earningsthe cost of certain foreign operations that we intendacquisition over the amount assigned to reinvest indefinitelytangible and identifiable intangible assets acquired less liabilities assumed.  At least annually, in the foreign operations.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, these earnings were distributedafter 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 U.S. incarrying value of the formassets may not be recoverable. Determination of dividends or otherwise, we would be subject to additional U.S. income taxes, subject to an adjustment for foreign tax credits,recoverability is based on the lowest level of identifiable estimated undiscounted cash flows resulting from use of the asset and foreign withholding taxes. Our current plans do not require repatriationits ultimate disposition. Measurement of earnings from foreign operations to fundany impairment loss is based on the U.S. operations because we generate sufficient domestic operating cash flow and have access to external funding under our lineamount by which the carrying value 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.

the asset exceeds its fair market value.

RECENT ACCOUNTING PRONOUNCEMENTS

Recently Issued Pronouncements

In March 2016,For a description of recent accounting pronouncements, including 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 paymentsexpected dates of adoption 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 haveestimated effects, if any, 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 beginningfinancial statements, see Note 3, Recent Accounting Pronouncements 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. ChangesNotes 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 consolidated results of operations, financial position, or cash flows.

In May 2014, the FASB issued additional guidance regarding revenue from contracts with customers. 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. In March 2016, the FASB issued 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 and transition requirements as the greater "contracts with customers" standard. We are required to adopt the standard, as amended, in the first quarter of 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, and cash flows.Consolidated Financial Statements.



ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 
The following discussesdiscussion of our exposure to market risk related to changes in interest rates and foreign currency exchange rates.  This discussionrates 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 forthdiscussed in Item 1A,Part I, "Item 1A. Risk Factors.Factors".

INTEREST RATE AND MARKET RISK
 
As of March 31, 2016 and 2015, we reported the following balances in cash and cash equivalents, short-term investments, and long-term investments:
  March 31,
(in millions) 2015 2016
Cash and cash equivalents $276.9
 $235.3
Short-term investments $97.9
 $160.1
Long-term investments $107.6
 $145.6

As of March 31, 2016, our investments were composed of Mutual Funds, US Treasury Notes, Government Agency Securities, Commercial Paper, Corporate Bonds, and Certificates of Deposits ("CDs").

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 limitsfloating-rate interest payments under our $1.275
billion term loan facility. In connection with the amountAcquisition, we entered into a Credit Agreement with Wells Fargo Bank, National Association, as administrative agent, and the lenders party thereto (the “Credit Agreement”). Borrowings under the Credit Agreement bear interest at a variable rate equal to (i) LIBOR plus a specified margin, or (ii) the base rate (which is the highest of credit(a) the prime rate publicly announced from time to time by Wells Fargo Bank, National Association, (b) the federal funds rate plus 0.50% or (c) the sum of 1% plus one-month LIBOR plus a specified margin.

On July 30, 2018, we entered into a 4-year amortizing interest rate swap agreement with Bank of America, NA as part of our overall strategy to manage our exposure to any one issuermarket risks associated with fluctuations in interest rates on the $1.275 billion term loan facility. As a matter of policy, we only enter into transactions that we believe will be highly effective at offsetting the underlying risk, 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 currentlyuse derivatives for trading or speculative purposes. Our objective is to mitigate the impact of interest expense fluctuations on our profitability related to interest rate changes, by minimizing movements in future debt payments with this interest rate swap.

The swap has an initial notional amount of $831 million and matures on July 31, 2022. The swap involves the receipt of floating-rate interest payments for fixed interest rate payments over the life of the agreement. We have designated this interest rate swap as a cash flow hedge, the abilityeffective portion of changes in the fair value of the derivative is recorded to liquidateother comprehensive income (loss) on the investments.accompanying balance sheets and reclassified into interest expense over the life of the agreement. We may sell our investments priorwill review the effectiveness of this instrument on a quarterly basis, recognize current period hedge ineffectiveness immediately in earnings and will discontinue hedge accounting if we no longer consider hedging to their stated maturities for strategic purposes, in anticipationbe highly effective. For additional details, refer to Note 16, Derivatives, of credit deterioration, or for duration management. No material realized or unrealized net gains or losses were recognized during the yearsaccompanying notes to condensed consolidated financial statements. During the fiscal year ended March 31, 20162019, we made payments of approximately $2.3 million on our interest rate swap and 2015.recognized $2.6 million within interest expense on the consolidated statement of operations. As of March 31, 2019, we had immaterial amount of interest accrued within accrued liabilities on the consolidated balance sheet. We had an unrealized pre-tax loss of approximately $8.6 million recorded within accumulated other comprehensive income (loss) as of March 31, 2019. A hypothetical 10% increase or decrease on market interest rates related to our outstanding term loan facility could result in a corresponding increase or decrease in annual interest expense of approximately $0.9 million.

Interest rates were relatively unchanged in the year ended March 31, 2016during Fiscal Year 2019 compared to the prior fiscal year. During the year ended March 31, 2016,Fiscal Year 2019, we generated approximately $1.8$3.1 million of interest income from our portfolio of cash equivalents and investments, compared to $1.4$3.8 million in fiscal year 2015. During the years ended March 31, 2016 and 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 on market interest rates related to our investment portfolio would have an immaterial impact on our results of operations.Fiscal Year 2018.


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,USD, could negatively affect our net revenues and gross margins as expressed in U.S. dollars.  There is a risk that we will have to adjust local currency product pricing due to competitive pressures if there is significant volatility in foreign currency exchange rates.

The primary currency fluctuations to which we are exposed are 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 CADAUD 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 $2.3 millionThe impact of changes in net foreign currency lossesrates recognized in the year ended March 31, 2016.other income and (expense), net was immaterial in both Fiscal years 2018 and 2019. 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 CAD 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, 20162019 (in millions):

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 6 to 12-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.

Approximately 44%45%, 44%49%, and 42%53% of net revenues in fiscal years 2016, 2015,Fiscal Years 2017, 2018, and 2014,2019, respectively, were derived from sales outside of the U.S., which were denominated primarily in EUR and GBP in each of the fiscal years.

As of March 31, 2016,2019, we had foreign currency put and call option contracts with notional amounts of approximately €59.4€76.8 million and £18.4£25.8 million denominated in EUR and GBP, respectively. If the USD is subjected to either a 10% appreciation or 10% depreciation versus these net exposed currency positions, we could realize a gain of $3.9$8.3 million or incur a loss of $5.1$7.0 million, respectively. As of March 31, 2015,2018, we also had foreign currency put and call option contracts with notional amounts of approximately €67.9€50.8 million and £28.6£15.6 million, denominated in EUR and GBP, respectively. Collectively, our option contracts hedge against a portion of our forecasted foreign currency denominated sales.

Change in Accounting Principle
As discussed in Note 3, to the Treadway Commission (COSO). consolidated financial statements, the Company changed the manner in which it accounts for revenues from contracts with customers in 2019.
Basis for Opinions
The Company'sCompany’s management is responsible for these consolidated 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'sthe Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on these the Company’s consolidatedfinancial statements on the financial statement schedules, and on the Company'sCompany’s internal control over financial reporting based on our integrated audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidatedfinancial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.
Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidatedfinancial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence supportingregarding the amounts and disclosures in the consolidatedfinancial statements, assessingstatements. Our audits also included evaluating the accounting principles used and significant estimates made by management, andas well as evaluating the overall presentation of the consolidatedfinancial statement presentation.statements. 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 discusseddescribed in Note 16 "Income Taxes" toManagement’s Report on Internal Control over Financial Reporting, management has excluded the Polycom business (‘Polycom’) from its assessment of internal controls over financial reporting as of March 30, 2019 because it was acquired by the Company in a purchase business combination during fiscal year 2019. We have also excluded Polycom from our audit of internal control over financial reporting. Polycom comprises wholly-owned subsidiaries whose total assets and total net revenues excluded from management’s assessment and our audit of internal control over financial reporting represent 34% and 46%, respectively, of the related consolidated financial statements,statement amounts as of and for the Company changed the manner in which it has classified deferred taxes on its consolidated balance sheet in 2016.year ended March 30, 2019.
Definition and Limitations of Internal Control over Financial Reporting

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.

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,the valuation of and assessment of recoverability of intangible assets and their useful lives, 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 Plantronicsthe Company 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 year 2016 had 53 weeksYears 2019, 2018, and ended on April 2, 2016, fiscal years 2015 and 20142017 each had 52 weeks and ended on March 28, 2015,30, 2019, March 31, 2018, and March 29, 2014,April 1, 2017, 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. The Company did not incur any material realized or unrealized gains or losses during Fiscal Year 2019.

As of March 31, 2016,2019, with the exception of assets related to the Company's deferred compensation plan and classified as trading securities, all investments were classified as available-for-sale, with unrealized gains and losses recorded as a separate component of accumulated other comprehensive income (loss) ("AOCI") in stockholders’ equity.  The specific identification method is used to determine the cost of disposed securities, with realized gains and losses reflected in other non-operating income and (expense), net.


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 other non-operating income and (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 up to 24 months, to reduce the volatility of cash flows related primarily to forecasted revenue and intercompany transactions denominated in certain foreign currencies.expenses. 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 entered into a 4-year amortizing interest rate swap in order to hedge against changes in cash flows (interest payments) attributable to fluctuations in the Company's variable rate debt. The effective portion of changes in the fair value of the derivative is recorded to other comprehensive income (loss) on the accompanying balance sheets and reclassified into interest expense over the life of the underlying debt as interest on the Company's floating rate debt is accrued. The Company reviews the effectiveness of this instrument on a quarterly basis, recognize current period hedge ineffectiveness immediately in earnings and will discontinue hedge accounting if the Company no longer considers hedging to be highly effective. 

The Company does not hold or issue derivative financial instruments for speculative trading purposes.  PlantronicsThe Company 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.  PlantronicsThe Company 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.net realizable value.  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. OurThe Company's 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,rights, 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, 2016,2019, the Company’s aggregate commitment to suppliers for parts used in the manufacture of the Company’s products was $150.9$287.5 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, 20162019, and 2015,2018, the off-balance sheet consigned inventory balances were $41.1$47.1 million and $33.4$48.8 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 on a straight-line basis 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. The Company performs a recoverability test to assess the recoverability of an asset group. Determination of recoverability is based on the lowest level of identifiable estimated undiscounted cash flows resulting from use of the asset group 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 and US Treasury Notes.Funds. 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 Government Agency Securities, Commercial Paper, Corporate Bonds,derivative foreign currency contracts, an interest rate swap, a term loan facility, and Certificates of Deposits ("CDs").


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.

5.50% Senior Notes. The fair value of Level 2 derivative foreign currency contracts and the interest rate swap is determined using pricing models that use observable market inputs. For more information regarding the Company's derivative assets and liabilities, refer to Note 16, Derivatives. The fair value of Level 2 long-term debt is5.50% Senior Notes and term loan facility are determined based on inputs that were observable in the market, including the trading price of the notes when available. For more information regarding the Company's 5.50% Senior Notes and term loan facility, refer to Note 10, Debt.

Level 3
The Company's unsecured revolving credit facility falls under the Level 3 hierarchy. The fair value of Level 3 revolving credit facility is determined based on inputs that were unobservable in the Company’s line of credit approximates its carrying value becausemarket. For more information regarding the interest rate is a variable rate that approximates rates currently availableCompany's debt, refer to Note 10, Debt in the accompanying notes to the Company. consolidated financial statements.

Revenue Recognition
 
The Company sells substantially allRevenue is recognized when obligations under the terms of a contract with the Company's customer are satisfied; generally, this occurs with the transfer of control of its products to end users through distributors, retailers, and carriers. The Company's revenueor services. Revenue is derived frommeasured as the saleamount 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,consideration the Company defers revenue when any significant obligations remain andexpects to date this has accountedreceive in exchange for less than 1%transferring goods or providing services. The majority of the Company's net revenues. Customer purchase orders and/or contracts are usedbusiness relates to determine the existence of an arrangement. Productphysical product shipments, for which revenue is considered deliveredgenerally recognized once it has been shipped and title and risk of loss have beenof the product are transferred to the customer. The Company assessesbelieves that transfer of title and risk of loss best represent the moment at which the customer’s ability to direct the use of and obtain substantially all the benefits of an asset have been achieved. The Company has elected to recognize the cost for freight and shipping when control over products have transferred to the customer as an expense in Cost of Revenues.

The Company's service revenue is recognized either over-time or at a point-in-time depending on the nature of the offering. Revenues associated with non-cancelable maintenance and support contracts comprise approximately 85% of the Company's overall service revenue and are recognized ratably over the contract term which typically ranges between one and three years. The Company believes this recognition period faithfully depicts the pattern of transfer of control for maintenance and support as the services are provided in relatively even increments and on a daily basis. For certain products, support is provided free of charge without the purchase of a separate maintenance contract. If the support is determined to rise to the level of a performance obligation, the Company allocates a portion of the transaction price to the implied support obligation and recognize service revenue over the estimated implied support period which can range between one month to several years, depending on the circumstances. Revenues associated with Professional Services are recognized when the Company has objectively determined that the obligation has been satisfied, which is usually upon customer acceptance.

The Company's contracts with customers often include promises to transfer multiple products and services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. The Company allocates the transaction price of a contract, to each identified performance obligation based on stand-alone selling price (“SSP”). A fixed discount is always subject to allocation in this manner. If the transaction price is fixed or determinable based uponconsidered variable, the selling termsCompany determines if the consideration is associated with one or many, but not all of the transactionperformance obligations and whetherallocates accordingly. Judgment is also required to determine the salesstand-alone selling price is subject to refund or adjustment.(“SSP") for each distinct performance obligation. The Company assesses collectability basedderives SSP for its performance obligations through a stratification methodology and consider a number of characteristics including consideration related to different service types, customer and geography characteristics. The Company uses a single amount to estimate SSP for items that are not sold separately, such as maintenance on a customer's credit quality, historical experience, and geographicterm-based licenses. In instances where SSP is not directly observable, such as when the Company does not sell the product or country-specific risks and economic conditionsservice separately, the Company determines the SSP using information that may affect a customer's ability to pay.include market conditions and other observable inputs.

RevenueOn occasion, the Company will fulfill only part of a purchase order due to lack of current availability for one or more items requested on an order. The Company's practice is recorded net of taxes collected from customers that are remitted to governmental authorities,ship what is on hand, with the collected taxes recorded as current liabilities until remitted toremaining goods shipped once the relevant government authority. Shipping and handling costs incurredproduct is in connection withstock which is generally less than one year from the saledate of products are included in costthe order. Depending on the terms of revenues.the contract or operationally, undelivered or backordered items may be canceled by either party at their discretion.

Sales through retail and distribution channelsThe distributor contracts are made primarily under agreements or commitments allowingthat allow for rights of return and include various sales incentive programs, such as back end rebates, advertising, price protection,discounts, marketing development funds, and other sales incentives. The Company hascan reasonably estimate the sales incentives due to an established sales history for these arrangementswith customers 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, 2016, 2015,2017, 2018, and 20142019 was $2.0$1.8 million,, $3.7 $0.9 million,, and $4.0$1.2 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.

Significant judgment is required in evaluating the Company's uncertain tax positions and determining its provision for (benefit from) 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,one-time, multiple tax years are subject to audit by various tax authorities.

Earnings (Loss) Per Share
 
BasicThe Company has a share-based compensation plan under which employees, non-employee directors, and consultants may be granted share-based payment 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. Historically, the two-class method of calculating earnings per share is computed by dividingdid not have a material impact on the net income for the period by the weighted average number of common shares outstanding during the period, less common stock subject to repurchase.  DilutedCompany's 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 purchasedcalculation under the Company’s employee stock purchase plan ("ESPP"), which are reflected in diluted earnings per share by application of the treasury stock method. UnderDuring periods of net loss, no effect is given to participating securities since they do not share in the treasury stock method,losses of the amount that the employee must pay for exercising stock options, the amountCompany. For further details refer to Note 18, Computation 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.  Earnings Per Common Share.

Comprehensive Income (Loss)
 
Comprehensive income (loss) 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 Company's functional currency of the Company’s foreign sales and marketing offices, except as noted in the following paragraph, is the local currencyU.S. Dollar (“USD") for all but one of the respective operations.  For these foreign operations, the Company translates assets and liabilities into U.S. dollars using the period-end exchange ratesits international subsidiaries located in effect as of the balance sheet date and translates revenues and expenses using the average monthly exchange rates.China.  The resulting cumulative translation adjustments related to this subsidiary are immaterial and are included as a component of stockholders' equity 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, assetsincome. Assets and liabilities denominated in foreign currencies other than the USD or for China, the Chinese Yuan Renminbi (“CNY”), are re-measured at the period-end orrates for monetary assets and liabilities and at historical rates as appropriate.for non-monetary assets and liabilities.  Revenues and expenses are re-measured at average monthly rates, which the Company believes to be a fair approximation ofapproximate actual rates.  CurrencyForeign currency transaction gains and losses are recognized in current operations.
other non-operating income and (expense), net, and have not been material for all periods presented.

Stock-Based Compensation Expense

The Company applies the provisions of the Compensation - Stock Compensation Topic of the FASB ASC 718, 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.


The Company followsadopted the tax law ordering approach to determine whennew stock-based compensation accounting guidance effective in Fiscal Year 2018. This new guidance requires excess tax benefits from stock-basedand tax deficiencies to be recognized in the provision for income taxes as discrete items in the period when the awards have been realized andvest or are recognized insettled, whereas previously such income tax effects were recorded as part of additional paid-in capital. WhenThe adoption of this guidance had an immaterial impact on the Company's effective tax deductionsrate for the year ended March 31, 2018. The amount of excess tax benefits or deficiencies will fluctuate from stock-based awards are less thanperiod-to-period based on the cumulative book compensation expense, the tax effectprice of the resulting difference (“shortfall”) is charged firstCompany’s stock, the volume of share-based instruments settled or vested, and the value assigned to additional paid-in capitalemployee equity awards under U.S. GAAP. For further details refer 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 2016 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.Note 17, Income Taxes.

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’The Company’s 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, 20162019, the Company's investments were composed solely of Mutual Funds. As of March 31, 2018, 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.

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,Two customers, D & H Distributing Company and Ingram Micro Group, accounted for 11.2%13.0% and 12.4%, respectively, of total net accounts receivable as of March 31, 2016. One customer2018. Three customers, Ingram Micro Group, ScanSource, and D&H DistributingDistributors, accounted for 11.1%21.3%, 19.2%, and 10.9%, respectively, of total net accounts receivable as of March 31, 2015.2019. The Company does not believe other significant concentrations of credit risk exist. PlantronicsThe Company 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 collectibilitycollectability 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. 

Related Party

The Company's vendor, Digital River, Inc. ("Digital River"), with whom the Company had an existing relationship prior to the acquisition of Polycom, Inc. ("Polycom") for e-commerce services, is a wholly owned subsidiary of Siris Capital Group, LLC ("Siris"). Triangle Private Holdings II, LLC ("Triangle") is also a wholly owned subsidiary of Siris. Immediately prior to the Company's acquisition of Polycom on July 2, 2018, Triangle was Polycom’s sole shareholder and, pursuant to the Company's stock purchase agreement with Triangle, currently owns approximately 16.0% of Plantronics' issued and outstanding stock. Additionally, in connection with the acquisition of Polycom, the Company entered into a Stockholder Agreement with Triangle pursuant to which it agreed to appoint two individuals to the Company's board of directors nominated by Triangle. As a consequence of these relationships, Digital River is considered a related party under Topic 850. The Company had immaterial transactions with Digital River during the year ended March 31, 2019.


Accounts Receivable Financing

As a result of the Polycom acquisition, the Company assumed a financing agreement with an unrelated third-party financing company (the "Financing Agreement") whereby the Company offers distributors and resellers direct or indirect financing on their purchases of Polycom's products and services. In return, the Company agrees to pay the financing company a fee based on a pre-defined percentage of the transaction amount financed. In certain instances, these financing arrangements result in a transfer of the Company's receivables, without recourse, to the financing company. If the transaction meets the applicable criteria under Topic 860, and is accounted for as a sale of financial assets, the related accounts receivable is excluded from the balance sheet upon receipt of the third-party financing company's payment remittance. In certain legal jurisdictions, the arrangements that involve maintenance services or products bundled with maintenance at one price do not qualify as sale of financial assets in accordance with the authoritative guidance. Accordingly, accounts receivable related to these arrangements are accounted for as a secured borrowing in accordance with Topic 860 and the Company records a liability for any cash received, while maintaining the associated accounts receivable balance until the distributor or reseller remits payment to the third-party financing company.

In Fiscal Year 2019, total transactions entered pursuant to the terms of the Financing Agreement were approximately $158.7 million, of which $81.8 million was related to the transfer of the financial asset. The financing of these receivables accelerated the collection of cash and reduced the Company's credit exposure. Included in "Accounts receivables, net" in the Company's consolidated balance sheet as of March 31, 2019 was approximately $40.5 million due from the financing company, of which $21.5 million was related to accounts receivable transferred. Total fees incurred pursuant to the Financing Agreement was $3 million for the year ended March 31, 2019. These fees are recorded as a reduction of net revenues in the Company's consolidated statement of operations.

Reclassifications

Certain prior year amounts have been reclassified for consistency with current year presentation. Each of the reclassifications was immaterial and had no effect on the Company's results of operations.

3.RECENT ACCOUNTING PRONOUNCEMENTS

Recently Issued Pronouncements

In 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”"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.”"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. ClassificationLease 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 Company adopted the new standard on March 31, 2019 using a modified retrospective approach. Under the modified retrospective approach, the Company will not adjust the comparative period financial information or make the new required lease disclosures for periods before the effective date. The Company will elect the short-term lease recognition exemption and will not recognize Right of Use (ROU) assets or lease liabilities for leases with a term less than 12 months. While the Company continues to assess all of the effects of adoption, the Company believes the most significant effects relate to (i) the recognition of new ROU assets and lease liabilities on the consolidated balance sheet and (ii) providing significant new disclosures about the Company's leasing activities. The new ROU assets and lease liabilities, which will be recognized on the consolidated balance sheet, consist primarily of real estate facilities. We are continuing to analyze and evaluate the ROU assets and lease liability using the Company's incremental borrowing rate at March 31, 2019. Upon adoption of ASC 842, all existing leases will be classified as either operating leases or finance leases. The Company plans to modify its business processes and controls to support the adoption of the new standard, including expanded review of new contracts. After the adoption of Topic 842, we will first report the ROU assets and lease liabilities as of June 30, 2019 in our Quarterly Report on Form 10-Q based on our lease portfolio as of that date.

In June 2016, the FASB issued guidance regarding the measurement of credit losses on financial instruments, which changes the impairment model for most financial assets. The new model uses a forward-looking expected loss method, which will generally result in earlier recognition of allowances for losses. 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 requires2021 with early adoption permitted beginning in the new guidance to be applied at the beginningfirst quarter of the earliest comparative period presented.Fiscal Year 2020. 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,statements and cash flows.related disclosures.

In July 2015,Recently Adopted Pronouncement

Except for the FASB issued additional guidance regardingchanges below, the subsequent measurementCompany has consistently applied the accounting policies to all periods presented in these consolidated financial statements. The Company adopted Topic 606 Revenue from Contracts with Customers to all contracts not

completed as of inventorythe initial application date of April 1, 2018. Topic 606 also includes Subtopic 340-40, Other Assets and Deferred Costs - Contracts with Customers, which requires the deferral of incremental costs of obtaining a contract with a customer. As a result, the Company has changed its accounting policy for revenue recognition as detailed below. The Company applied Topic 606 using the modified retrospective method by requiring inventoryrecognizing the cumulative effect of initially applying Topic 606 as an adjustment to the opening balance of retained earnings at April 1, 2018. Therefore, the comparative information has not been adjusted and continues to be measuredreported in accordance with its historic accounting under Topic 605. The details of the notable changes and quantitative impact of the changes are set out below.

Software Revenue: The Company historically deferred revenue for the value of software where vendor specific objective evidence ("VSOE") of fair value had not been established for undelivered items. Under Topic 606, revenue for such licenses is recognized at the lowertime of costdelivery, rather than ratably, as the VSOE requirement no longer applies and net realizable value.the value of the remaining services are not material in the context of the contract. All deferred revenue pertaining to such licenses was eliminated as a cumulative effect adjustment of implementing the new standard.

Marketing Development Funds: The Company frequently provides marketing development funds to its distributor and retail customers. Historically, its marketing development funds were recognized as a reduction of revenue at the later of when the related revenue is recognized or when the program is offered to the channel partner. Applying the criteria of Topic 606, these marketing development programs qualify as variable consideration, and are assigned as a reduction of the transaction price of the contract. This results in a timing difference such that all or some of the funds related to a program may be recognized in different periods than under Topic 605, depending on the circumstances.

Discount, Rebates and Pricing Reserves: The Company establishes reserves for Discounts and Rebates at the end of each fiscal period. These reserves are estimated based on current relevant and historical data, but there can be some variability associated with unforeseen changes in customer claim patterns. Under Topic 606, in cases where there is uncertainty around the variable consideration amount, a constraint on that consideration must be considered. The impact of this constraint may result in slightly higher reserves than were recorded under the legacy methodology.

The Company has historically recorded reserves for customer-related pricing protection which is based on contractual terms and the legal interpretation thereof. Topic 606 prescribes an “expected value” method to estimating variable consideration which involves the sum of probability-weighted amounts for a range of possible outcomes. Applying this method may result in a slightly lower reserve than the reserves under legacy methodology.

Additionally, the balance sheet presentation of certain reserve balances previously shown net within accounts receivable are now presented as refund liabilities within current liabilities.

On July 2, 2018 the Company acquired Polycom, a privately held Company who had not yet adopted Topic 606. In addition to increasing the magnitude of certain of the items listed above, the acquisition introduced several additional areas of impact. The most notable areas of impact are:

Term Licenses: Legacy accounting standards required that revenue for term-based software licenses be recognized ratably when VSOE of fair value had not been established for undelivered items such as post-contract support. Under Topic 606, revenue for such licenses is recognized at the time of delivery, rather than ratably, as the VSOE requirement no longer applies.

Cost of Obtaining a Contract: Under legacy guidance, in certain circumstances an entity could have elected to capitalize direct and incremental contract acquisition costs, such as sales commissions. Under Topic 606 and related guidance, an entity is required to adoptcapitalize costs that are incremental to obtaining a contract if it expects to recover them, unless it elects the standardpractical expedient for costs with amortization periods of one year or less. This new provision affects the Company as it will capitalize those costs if the anticipated amortization period is greater than one year and the criteria have been met.

The cumulative effect of the changes made to the Company's consolidated April 1, 2018 balance sheet for the adoption of Topic 606 was as follows (in thousands):

4. ACQUISITION

Polycom Acquisition

On July 2, 2018 ("Acquisition Date"), the Company completed the acquisition of Polycom based upon the terms and conditions contained in the Purchase Agreement dated March 28, 2018 ("the Acquisition"). The Company believes the Acquisition will better position Plantronics with its fiscalchannel partners, customers, and strategic alliance partners by allowing the Company to pursue additional opportunities across the Unified Communications & Collaboration ("UC&C") market in both hardware end points and services.

At the closing of the Acquisition, the Company acquired Polycom for approximately $2.2 billion with the total consideration consisting of (1) 6.4 million shares of the Company's common stock (the "Stock Consideration") valued at approximately $0.5 billion and (2) approximately $1.7 billion in cash net of cash acquired (the "Cash Consideration"), resulting in Triangle, which was Polycom’s sole shareholder, owning approximately 16.0% of the Company immediately following the acquisition. The consideration paid at closing was subject to a working capital, tax and other adjustments. This transaction was accounted for as a business combination and the Company has included the financial results of Polycom in the Consolidated Financial Statements since the date of acquisition.

The preliminary allocation of the purchase price to the estimated fair value of the assets acquired and liabilities assumed at the acquisition date is as follows:
(in thousands) July 2, 2018
ASSETS  
Cash and cash equivalents $80,139
Trade receivables, net 165,449
Inventories 109,074
Prepaid expenses and other current assets 68,451
Property and equipment, net 79,497
Intangible assets 985,400
Other assets 27,237
Total assets acquired $1,515,247
   
LIABILITIES  
Accounts payable $80,653
Accrued payroll and related liabilities 44,538
Accrued expenses 144,051
Income tax payable 27,044
Deferred revenue 115,061
Deferred income taxes 98,342
Other liabilities 51,796
Total liabilities assumed $561,485
   
Total identifiable net assets acquired 953,762
Goodwill 1,262,883
Total Purchase Price $2,216,645

The Company’s purchase price allocation is preliminary and subject to revision as additional information related to the fair value of assets and liabilities are finalized. The estimate of fair value and purchase price allocation were based on information available at the time of closing the Acquisition and the Company continues to evaluate the underlying inputs and assumptions that are being used in fair value estimates. Accordingly, these preliminary estimates are subject to retrospective adjustments during the measurement period, not to exceed one year, endingbased upon new information obtained about facts and circumstances that existed as of the date of closing the Acquisition. The acquisition has preliminarily resulted in $1,263 million of goodwill, which represents the excess of the purchase price over the fair value of identifiable assets acquired and liabilities assumed. Additionally, the purchase price is subject to change due to potential tax obligations related to unsettled intercompany transactions and potential resolution of certain contingent liabilities.


Since the acquisition date, we have recorded measurement period adjustments to reflect facts and circumstances in existence as of the acquisition date. These adjustments included deferred tax and tax liabilities of $44.0 million, a working capital adjustment of $8.0 million and various other immaterial adjustments of $4.2 million, resulting in a decrease to goodwill of approximately $56.2 million.

The Company incurred approximately $19.2 million in acquisition related expenses which are recorded in selling, general, and administrative expenses in its the consolidated statement of operations for the year ended March 31, 2018, but may elect2019.

The following table shows the fair value of the separately identifiable intangible assets at the time of acquisition and the period over which each intangible asset will be amortized:

(in thousands, except for remaining life) Fair Value Weighted-Average Amortization Period

Existing technology relates to adopt earlier as permittedproducts for voice, video and platform products. The Company valued the developed technology using the discounted cash flow method under the standard.income approach. This method reflects the present value of the projected cash flows that are expected to be generated by the developed technology less charges representing the contribution of other assets to those cash flows. The adoptioneconomic useful life was determined based on the technology cycle related to each developed technology, as well as the cash flows over the forecast period.

Customer relationships represent the fair value of future projected revenue that will be derived from sales of products to existing customers of Polycom. Customer relationships were valued using the discounted cash flow method as described above and the distributor method under the income approach. Under the distributor method, the economic profits generated by a distributor are deemed to be attributable to the customer relationships. The economic useful life was determined based on historical customer turnover rates.

Order backlog was valued separately from customer relationships using the discounted cash flow method under the income approach. This method reflects the present value of the projected cash flows that are expected to be generated by order backlog less costs to fulfill. The economic useful life was determined based on the period over which the order backlog is expected to be fulfilled.

Trade name/trademarks relate to the “Polycom” trade name and related trademarks. The fair value was determined by applying the profit allocation method under the income approach. This valuation method estimates the value of an asset by the profit saved because the company owns the asset. The economic useful life was determined based on the expected life of the trade name and trademarks and the cash flows anticipated over the forecasted periods at the time of the acquisition.

The fair value of in-process technology was determined using the discounted cash flow method under the income approach. This method reflects the present value of the projected cash flows that are expected to be generated by thin-process technology, less charges representing the contribution of other assets to those cash flows. In Fiscal Year 2019, the Company reclassified approximately $28.1 million of completed in-process research and development into existing technology and began amortizing over the estimated useful life. The Company expects the remaining in-process research and development to be completed, transferred to existing technology, and begin amortizing in Fiscal Year 2020.

The Company believes the amounts of purchased intangible assets recorded above represent the fair values of and approximate the amounts a market participant would pay for these intangible assets as of the Acquisition Date.

Goodwill is primarily attributable to the assembled workforce, market expansion, and anticipated synergies and economies of scale expected from the integration of the Polycom business. The synergies include certain cost savings, operating efficiencies, and other strategic benefits projected to be achieved. Goodwill is not expected to have a material impact onbe deductible for tax purposes.

The actual total net revenues and net loss of Polycom included in the Company's consolidated statement of operations for the period July 2, 2018 to March 31, 2019 are as follows:

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 onnecessarily indicative of the Company's consolidated results of operations financial position, or cash flows.

In May 2014,of the FASB issued additional guidance regarding revenue from contracts with customers. Whilecombined business had the standard supersedes existing revenue recognition guidance, it closely aligns with current GAAP. Under the new standard, revenue will be recognizedAcquisition actually occurred at the time a goodbeginning of fiscal year 2018 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 dateresults of adoption. In March 2016, the FASB issued 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 understandabilityits future operations of the implementation guidance and have the same effective date and transition requirements as the greater "contracts with customers" standard. The Company is required to adopt the standard, as amended, in the first quarter of 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, and cash flows.combined business.

The expected stock price volatility for the years ended March 31, 2016, 2015,2017, 2018, and 20142019 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.


Long Term Incentive Plan (LTIP)

Prior to the Company's acquisition of Polycom, certain Polycom employees were granted incentive rights under the Polycom, Inc. 2016 Long-Term Incentive Plan (“2016 LTIP”).  As of the date of acquisition, Plantronics assumed the role of payer to participants of the plan through its payroll but is indemnified by Triangle for obligations under the plan.  The acquisition accelerated vesting at 75% of awards held by participants in service as of that date and triggered an initial amount due to such participants. The cash purchase price of the acquisition was reduced by this initial obligation.  The remaining 25% of awards will vest upon one-year anniversary of the acquisition. Any future payments above the initial obligation under the plan, provided that the vesting requirements are satisfied, require Triangle to fund Plantronics in order to pay participants for any amount in excess of the purchase price reduction.
 At July 2, 2018, $7.9 million was recognized in Accrued liabilities assumed from Polycom and was paid in the second quarter of fiscal 2019.  The Company recognized an immaterial amount of compensation expense during the fiscal year ended March 31, 2019 in respect of the awards vesting on the one-year anniversary, which will be payable in the second quarter of fiscal 2020.  The amount due as of the acquisition date is based on cash paid to Triangle that was distributed to its parents.  Future distributions to its parents of cash made available to Triangle from the release of escrow accounts or the sale of shares issued in the transaction would trigger further compensation due to incentive rights holders under the plan.  Plantronics is indemnified for any obligations in excess of the reduction to purchase price.

11. RESTRUCTURING AND OTHER RELATED CHARGES

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

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.

12.13. COMMON STOCK REPURCHASES

From time to time, the Company's Board authorizesof Directors (the "Board") has authorized 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. DuringOn November 28, 2018, the years ended Company's Board of Directors approved a 1 million shares repurchase program expanding its capacity to repurchase shares to approximately 1.7 million shares. As of March 31, 2016, 2015, and 2014, the Company repurchased 9,077,223, 2,221,448, and 1,949,407 shares of its common stock, respectively, for a total cost of $497.4 million, $112.9 million, and $85.7 million, respectively, and at an average price per share of $54.80, $50.84, and $43.94, respectively.
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, and 2014 were made in the open market. As of March 31, 2016,2019, there remained 634,0111,369,014 shares authorized for repurchase under the repurchase program approved by the Board on January 29, 2016.Board.

TheRepurchases by the Company withheld shares valued at $11.1 million duringpursuant to Board-authorized programs are shown in the year ended March 31, 2016, compared to $7.6 million in fiscal year 2015, and $6.2 million in fiscal year 2014, in satisfaction of employee tax withholding obligations upon the vesting of restricted stock granted under the Company's stock plans. following table:

14.15.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. Effective January 1, 2019, the policy was modified, whereby the Company matches 100% of the first 3% of employees' compensation and matches 50% of the second 3% of employee compensation. There is no longer any non-elective Company contribution. The Company reserves the right to modify its policies at any time, including increasing, decreasing, or eliminating contribution matching and vesting requirements.

15.16.FOREIGN CURRENCY DERIVATIVES

Foreign Currency Derivatives

The Company's foreign currency derivatives consist primarily of foreign currency forward exchange contracts and option contracts, and cross-currency swaps.contracts.  The Company does not purchase derivative financial instruments for speculative trading purposes.  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 that it would incur 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 agreementscontracts was equal to the net assetcarrying value of the Company's derivativesderivative assets as of March 31, 2016.2019.  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 singleone 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 Plantronicsthe Company and the counterparty as a result of multiple, separate derivative transactions. As of March 31, 2016,2019, the Company has International Swaps and Derivatives Association (ISDA) agreements with four applicable banks and financial institutions which contain netting provisions. PlantronicsThe Company 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.

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, 20162018, and March 31, 2015,2019, no cash collateral had been received or pledged related to these derivative instruments.

Non-Designated Hedges
 
As of March 31, 2016,2019, the Company had foreign currency forward contracts denominated in Euros ("EUR"), British Pound Sterling ("GBP"), and Australian Dollars ("AUD"), and Canadian Dollars ("CAD").  The Company does not elect to obtain hedge accounting for these forward contracts. These forward contracts hedge against a portion of the Company’s foreign currency-denominated cash balances, receivables, and payables.

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 six6 to eleven month12-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 monththree-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.  Asnotional value of March 31, 2016, the Company had foreign currency putCompany's outstanding EUR and callGBP option contracts of approximately €59.4 million and £18.4 million.  As of March 31, 2015, the Company had foreign currency put and call option contracts of approximately €67.9 million and £28.6 million. As of March 31, 2016  the Company had foreign currency forward contracts at the end of approximately €23.9 million and £9.1 million.

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 $1.1 million, net of tax, in AOCI asAs of March 31, 2016 is expected to be reclassified to net revenues during the next 12 months due to the recognition of the hedged forecasted expenditures. As of 2018, and March 31, 2016 and 2015,2019, the Company had foreign currency swap contracts of approximately MXN 481.031.8 million and MXN 431.9149.7 million,, respectively.

Interest Rate Swap

On July 30, 2018, the Company entered into a 4-year amortizing interest rate swap agreement with Bank of America, NA. The swap has an initial notional amount of $831 million and matures on July 31, 2022. The swap involves the receipt of floating-rate interest payments for fixed interest rate payments at a rate of 2.78% over the life of the agreement. The Company has designated this interest rate swap as a cash flow hedge. The purpose of this swap is to hedge against changes in cash flows (interest payments) attributable to fluctuations in the Company's variable rate debt. The derivative is valued based on prevailing LIBOR rate curves on the date of measurement. The Company also evaluates counterparty credit risk when it calculates the fair value of the swap. The effective portion of changes in the fair value of the derivative is recorded to other comprehensive income (loss) on the accompanying balance sheets and reclassified into interest expense over the life of the underlying debt as interest on the Company's floating rate debt is accrued. The Company reviews the effectiveness of this instrument on a quarterly basis, recognize current period hedge ineffectiveness immediately in earnings and will discontinue hedge accounting if the Company no longer considers hedging to be highly effective. This hedge was fully effective at inception on July 30, 2018 and as of fiscal year ended March 31, 2019. During the fiscal year ended March 31, 2019, the Company recorded a loss of $2.6 million on its interest rate swap derivative designated as a cash flow hedge.

The effective tax rate for fiscal years 2016, 2015, and 2014 was 16.8%, 22.7%, and 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 plus 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. This 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. The U.S. federal research tax credit expired December 31, 2014, 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 only available for three quarters since the tax credit expired December 31, 2013 prior to it being retroactively reinstated in January 2015.

The effective tax rate for fiscal years 2016, 2015, and 2014 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 $657.3 million at March 31, 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 U.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 withdrawn 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 for which it has recorded a deferred tax liability in the current period. The Company will continue to monitor developments related to the case and the potential impact on its consolidated financial 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.

(1) Valuation allowance on state deferred tax assets are net of federal tax impact.
(2) The Company's deferred tax assets for the fiscal year endingFiscal Year ended March 31, 20162018 and the long-term portion of the Company's deferred tax assets for the fiscal year ending March 31, 2015,2019, 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 establishedlong-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 $2.0$15.8 million as of March 31, 20162019 included (1) $9.8 million related to the net operating losses of a foreign subsidiary which can be carried forward indefinitely, but are not anticipated to be utilized as a result of an insufficient recent history of earnings coupled with changes to the company’s anticipated operating structure abroad; (2) $5.7 million for deferred tax assets related to state net operating losses in the current year as a result of changes to the company’s operating structure in the United States, after applying state tax rates and federal tax benefit; and (3) $0.3 million related to China net operating losses, which begin to expire in Fiscal Year 2021. The valuation allowance of $2.5 million as of March 31, 2018 was related to the net operating losses of a foreign subsidiary with an insufficient recent history of earnings to support the realization of thetheir deferred tax asset.assets, as well as to excess California research credit carryforwards.
During the second quarter of Fiscal Year 2019, the Company released its partial valuation allowance against California Research and Development credits. This release was a direct result of the Acquisition, as fewer credits are expected to be generated in California as a percentage of worldwide taxable income in future periods.

The Company has California research and development credit carryforwards for income tax purposes of $11.7 million that can be carried forward indefinitely as well as $3.9 million of U.S federal net operating losses that have limited use under US Internal Revenue Code section 382. These losses begin to expire in fiscal year 2024.

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, 2016, 2015,2017, 2018, and 2014,2019, the Company had $12.7$12.9 million,, $12.8 $12.6 million,, and $12.6$26.5 million,, respectively, of unrecognized tax benefits.  The increase of uncertain tax positions when compared to the prior year is predominantly due to acquired uncertain tax benefits of Polycom. The unrecognized tax benefits as of March 31, 20162019 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:

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 $1.6$1.4 million and $1.8$2.0 million as of March 31, 20162018 and 2015,2019, 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 currently being audited by the Internal Revenue Service for fiscal year 2016. All federal tax matters have been concluded for tax years prior to fiscal year 2013. The California Franchise Tax Board completed its examination of our 2007Fiscal Year 2014. Foreign 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. ForeignState 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 2015.Fiscal Year 2012 and Fiscal Year 2014, respectively.

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 timingpossible reduction in liabilities for uncertain tax that may impact the statements of any resolution and/or closureoperations in the next 12 months is approximately $1.2 million.

During Fiscal 2019, the Company completed its computation of the tax examinations is not certain.act in accordance with Staff Accounting Bulletin SAB 118 (“SAB 118”), which addressed concerns about reporting entities’ ability to timely comply with the requirements to recognize the effects of the Tax Cuts and Jobs Act. During the fiscal year ended March 31, 2018, the Company recorded a provisional toll charge of $79.7 million. During fiscal year 2019, the toll charge was completed resulting in a tax benefit of $0.8 million. The Company has paid $21.5 million of the toll charge and the remaining toll charge liability of $57.3 million will be paid over the next six years. The Company also paid a $6.9 million toll charge in October 2018 related to Polycom’s pre-acquisition period. During the fiscal year ended March 31, 2018, the Company recorded a provisional expense of $5.0 million related to state income taxes and foreign withholding taxes for unrepatriated foreign earnings through the Tax Act’s enactment date, as the Company no longer intends to indefinitely reinvest foreign earnings abroad. During fiscal year 2019, the toll charge computation of state and foreign withholding taxes was completed resulting in the recognition of a tax benefit of $3.2 million. The effect of the SAB 118 measurement period adjustments on the effective tax rate for Fiscal Year 2019 was (2.1)%, Polycom recorded a toll charge which was paid in October 2018 with the filing of its 2017 tax return.

For the global intangible low-taxed income provisions of the Tax Act, the Company has selected an accounting policy to record related period costs if and when incurred.

17.18.COMPUTATION OF EARNINGS PER COMMON SHARE

TheBasic earnings (loss) per share is calculated by dividing net income (loss) associated with common shareholders by the weighted-average number of common shares outstanding during the period. Diluted earnings (loss) per share assumes the issuance of additional shares of common stock by the Company has a share-based compensation plan under which employees, non-employee directors,upon exercise of all outstanding stock options and consultants may be granted share-based awards, including sharesvesting of restricted stock, on which non-forfeitable dividends are paid on unvested shares. As such, shares of restrictedif the effect is dilutive, in accordance with the treasury stock are considered participating securities under themethod or two-class method of calculating earnings per share. The two-class method of calculating earnings per share did not have a material impact on(whichever is more dilutive).

In Fiscal Year 2019, the Company's deferred revenue balance was $193.9 million, which represents 11.6% of total net revenues. In Fiscal 2018 and 2017, the Company’s deferred revenue balance was $3.0 million and $2.0 million respectively, which represents less than 1% of total net revenues.

Upon establishment of creditworthiness, the Company may extend credit terms to its customers which typically ranges between 30 and 90 days from the date of invoice depending on geographic region and type of customer. The Company typically bills upon product hardware shipment, at time of software activation or upon completion of services. Revenue is not generally recognized

in advance of billing, and any resulting contract asset balances at period end are not considered material. None of the Company's contracts are deemed to have significant financing components.

Sales, value add, and other taxes collected concurrent with revenue producing activities are excluded from revenue.

The Company's indirect channel model includes both a two-tiered distribution structure, where the Company sells to distributors that subsequently sell to resellers, and a one-tiered structure where the Company sells directly to resellers. For these arrangements, transfer of control begins at the time access to the Company's services is made available to the end customer and entitlements have been contractually established, provided all other criteria for revenue recognition are met.

Commercial distributors and retailers represent the Company's largest sources of net revenues. Sales through its distribution and retail channels are made primarily under agreements allowing for rights of return and include various sales incentive programs, such as back end rebates, discounts, marketing development funds, price protection, and other sales incentives. The Company has an established sales history for these arrangements and the Company records the estimated reserves at the inception of the contract as a reflection of the reduced transaction price. Customer sales returns are estimated based on historical data, relevant current data, and the monitoring of inventory build-up in the distribution channel. Revenue reserves represent a reasonable estimation made by management and are subject to significant judgment. Estimated reserves may differ from actual returns or incentives provided, due to unforeseen customer return or claim patterns or changes in circumstances. For certain customer contracts which have historically demonstrated variability, the Company has considered the likelihood of being under-reserved and have considered a constraint accordingly. Provisions for Sales Returns are presented within Accrued Liabilities in the Company's Consolidated Balance Sheets. Provisions for promotions, rebates, and other sales incentives are presented as a reduction of Accounts Receivable unless there is no identifiable right offset, in which case they are presented within Accrued Liabilities on its Consolidated Balance Sheets. Refer to Note 7, 2016Details of Certain Balance Sheet Accounts, 2015, or 2014. for additional details.

For certain arrangements, the Company pays commissions, bonuses and taxes associated with obtaining the contracts. The Company capitalizes such costs if they are deemed to be incremental and recoverable. The Company has elected to use the practical expedient to record the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the entity otherwise would have recognized is one year or less. Determining the amortization period of costs related to obtaining a contract involves judgment. Capitalized commissions and related expenses, on hardware sales and services recognized at a point in time generally have an amortization period of less than one year. Maintenance-related performance obligations generally have an amortization period greater than one year when considering renewals. Capitalized commissions are amortized to Sales and Marketing Expense on a straight-line basis. The capitalized amount of incremental and recoverable costs of obtaining contracts with an amortization period of greater than one year are $3.1 million as of March 31, 2019. Amortization of capitalized contract costs for the Fiscal Year ended March 31, 2019 was immaterial.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE
 
There have been no disagreements with accountants on any matter of accounting principles and practices or financial disclosure. 

ITEM 9A.  CONTROLS AND PROCEDURES
 
Evaluation of disclosure controls and procedures
 
Our management evaluated, with the participation of our Chief Executive Officer and our Chief Financial Officer, the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Form 10-K.  Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and procedures are effective at the reasonable assurance level to ensure that information we are required to disclose in reports that we file or submit under the Securities Exchange Act of 1934 (i) is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms, and (ii) is accumulated and communicated to Plantronics’the Company’s management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Our disclosure controls and procedures are designed to provide reasonable assurance that such information is accumulated and communicated to our management.  Our disclosure controls and procedures include components of our internal control over financial reporting.  Management’s assessment of the effectiveness of our internal control over financial reporting is expressed at the level of reasonable assurance because a control system, no matter how well designed and operated, can provide only reasonable, but not absolute, assurance that the control system’s objectives will be met.
 

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended).  Our management conducted an evaluation of the effectiveness of our internal control over financial reporting based on the criteria set forth in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”).  Based on this evaluation, our management has concluded that our internal control over financial reporting was effective as of March 31, 20162019.  .  

On July 2, 2018, the Company completed its acquisition of Polycom. In conducting its assessment of the effectiveness of the Company’s internal control over financial reporting as of March 30, 2019, management has elected to exclude Polycom from that assessment, as permitted under SEC rules. The Company is in the process of integrating the historical internal control over financial reporting of Polycom with the rest of the Company. Polycom’s operations are included in the Company’s 2019 consolidated financial statements for the period from July 2, 2018 to March 31, 2019 and represented 34% of the Company’s consolidated total assets as of March 31, 2019 and 46% of the Company’s consolidated total net revenues for the year ended March 31, 2019.

The Company’s independent registered public accounting firm, PricewaterhouseCoopers LLP, has issued a report on our internal control over financial reporting, which appears on page 4256 of this Form 10-K.
 
Changes in internal control over financial reporting
 
There has been no change in our internal control over financial reporting during the fourth quarter of fiscal year 2016Fiscal Year 2019 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
