The Turtle Beach® brand is highly regarded among the over 700 million gamers in North America and Europe where thecompany has a dominant market share in gaming headsets for Xbox and PlayStation® consoles. In addition to its gaming headset business, the companyacquired and developed an innovative and patent-protected sound technology that delivers immersive, directional audio called HyperSound® via a reversemerger with Parametric Technologies in January 2014.Turtle Beach Corporation was incorporated in the state of Nevada in 2010 and the company’s stock is traded on the Nasdaq Global Market under thesymbol HEAR.VTB Holdings, Inc. (“VTBH”), the subsidiary of Turtle Beach and the parent holding company of Voyetra Turtle Beach, Inc. (“VTB”) and Turtle BeachEurope Limited (“TB Europe”), together the historical headset business, was incorporated in the state of Delaware in 2010 with operations principally locatedin Valhalla, New York. VTB was incorporated in the state of Delaware in 1975.Headset BusinessTurtle Beach launched its first gaming headset in 2005 and has grown to be the leading brand in console gaming headsets. The Company designs andmarkets premium audio peripherals for both Xbox and PlayStation® game consoles, as well as for PC, Mac® and mobile/tablet devices. Additionally, TurtleBeach is an officially-licensed partner of Microsoft, delivering innovative and groundbreaking first-to-market products for their latest family of consolesincluding the latest Xbox One X. Turtle Beach headsets are distributed internationally across North America, South America, Europe, the Middle East, Africa,Australia, and Asia, and are sold at thousands of storefronts, including major retailers such as Amazon, Argos, Best Buy, Game, GameStop, EB Games, Target,and Walmart.The Company offers a variety of headsets, spanning multiple retail price points ranging from $20 to $300, with offerings compatible across all majorgaming platforms. Our price tiers correspond to customer profiles, beginning with “Entry-Level” gamers and progressing through “Casual,” “Enthusiast,”“Core,” and professional gamers including eSports players and fans. Each successive price tier incorporates a higher level of finish, features and technology,progressing from passive mono to amplified stereo, surround sound, and programmable surround sound. Premium headsets have padded leather headbands,accent stitching, and noise-isolating memory foam ear cups. Other features found in select premium headset models include removable microphones,breakaway cables and “charge-and-play” batteries that allow gamers to continue playing even as they recharge their batteries. As gaming consoles haveevolved from dedicated video game platforms to home entertainment hubs, and as mobile and tablet devices have become mainstay platforms forentertainment, we have continued to evolve our headsets to reflect how content is consumed.Each Turtle Beach headset is designed for a “primary” platform, such as a specific console or for the personal computer platform, though many can beused with multiple platforms, and most are compatible with mobile/tablet devices via a standard 3.5mm jack and Bluetooth® connectivity. A primaryplatform designation paired with our unique, platform-specific packaging designs often result in our products being assorted in multiple sections in-store byretailers, increasing the prominence of the Turtle Beach brand and its products in physical retail locations and online catalogs.In 2017, Turtle Beach was the leading console gaming headset manufacturer in North America with a 42.1% dollar share of the market, as noted by theDecember 2017 sales tracking data from The NPD Group, Inc (“NPD Group”), holding six of the top ten selling Xbox One models and four of the top tenselling PlayStation®4 models by revenue. Market share in the UK was 51.8% in 2017 as reported by GFK. The company has achieved these high globalmarket shares by delivering high quality products that often include first-to-market innovations and robust features, in addition to superior sound andunmatched comfort - all key factors gamers look for when shopping for a gaming headset. HyperSound BusinessHyperSound technology is a pioneering audio solution that projects sound in a highly directional manner. HyperSound directs a beam of audio totargeted listeners in a specific spot, delivering an immersive, 3D-like audio experience as well as benefits for people with hearing loss. The Company has alsodeveloped and patented the capability to created directed audio from a transparent “speaker” using a set of layered materials on glass. The technology hasapplications in multiple verticals including retail displays where isolated audio is desired, personal or business audio where a directed beam of audio offersprivacy benefits, and living room audio solutions for people with hearing loss.Our business model for HyperSound has evolved into a licensing strategy, focusing on out licenses to companies in the retail aspect for more precisemarketing. In October 2017, we signed a licensing contract with Waves Systems to incorporate3 HyperSound technology for customer contact points such as retail point of sales, kiosks, digital signage, wayfinding, museum exhibits, meeting halls andmore.Industry OverviewGaming Headset MarketGaming headsets are part of a global, growing gaming market sized at over $100 billion. Global gaming now exceeds both global cinema and globalmusic market sizes with over 2.1 billion active gamers worldwide. Gaming peripherals are a $2 billion business globally with over 75%, over $800 million, ofthat market in the Americas and Europe where the company’s business is focused. Gaming headsets are nearly half of that, at over $1 billion in global marketsize.eSports is a global phenomena where professional gamers train, compete, win prize money and attract fans similar to other professional sports. There areover 140 million eSports enthusiasts globally and growing quickly. Gaming headsets are a must-have piece of equipment for competitive gaming.Xbox and PlayStation® consoles are the dominant gaming platforms in North America and Europe. Many gamers play online where gaming headsets -which include a microphone and allow players to communicate with one another in real time - provide the ability to jump in and engage in the industry’smost popular games and franchises. Gaming headsets also create a more immersive and rich gaming experience. In addition to consoles, personal computersare a key platform for gaming and utilize similar style headsets with the requisite benefits. Gaming on mobile/tablet devices represents about a third of theglobal gaming market and headsets can be used for mobile gaming, but Xbox, PlayStation®, and PC gaming are by far the largest drivers of gaming headsetuse. Nintendo Switch™ has emerged as a popular gaming platform, although much less of a driver of gaming headset sales.Historically, Microsoft and Sony go through cycles where their respective console platform is changed and/or updated to a significant new version. Inholiday 2013, Microsoft launched Xbox One to replace Xbox 360, while Sony launched Playstation®4 to replace Playstation®3. Those console transitionscreated a major disruption for gaming headsets and other accessories because the fundamental connectivity to the new platforms changed. From 2013 to2015, that disruption negatively impacted the gaming accessory market as the old generation headset business rapidly declined and new headsets had to bedeveloped for the new consoles. In 2016 and 2017, respectively, both Microsoft and Sony launched “Pro” versions of their latest console platforms whichdidn’t create any disruption for the gaming headset business and the Company believes this is a good indication that any potential future console changeswill not be as disruptive.In addition to console sales, the Xbox, PlayStation®, and PC gaming markets are driven by major games which encourage players to buy equipmentand accessories. On Xbox and PlayStation®, tentpole games like Call of Duty®, Destiny, Battlefront, Grand Theft Auto and more recently Fortnite andPlayerUnknown's Battlegrounds are examples of major franchises that feature online multiplayer modes, which drive gaming headset sales. Many of theseestablished franchises launch new titles annually leading into the holidays, which furthers the popularity of gaming headsets as gift items. As a result, thegaming headset business is highly seasonal, often with 45%-55% of the business occurring in the fourth quarter. The gaming headset business can alsoexpand or contract based on the success of these major game launches.During 2017, PlayerUnkown’s Battlegrounds introduced a new style of multiplayer game known as “Battle Royal,” where players compete in a large,but shrinking maps until there is a single winner left. Players can play on teams, and audio cues are very helpful to surviving, making headsets a keyaccessory for this type of game. Epic Games introduced Fortnite which includes a similar format in late 2017, but with a more kid-friendly feel. Both gameshave soared in popularity over the past months with large and continually growing audiences of both players and spectators via content sharing platformslike Twitch, YouTube, Xbox’s Mixer, and PlayStation® Now.Gaming headsets are sold through major retailers such as Argos, Best Buy, GameStop, Target and Walmart as well as online retailers such as Amazonand NewEgg. Brick and mortar retailers often have “kiosks” which enable shoppers to “try before they buy,” offering consumers the opportunity toexperience each headset’s specific fit, feel and overall audio quality.Over the past few years, retail channel inventory levels have varied significantly. At the end of 2016, channel inventories were much higher than normalin North America and Europe due to weaker than expected performance of the major holiday game releases. This impacted revenues for the Company in thefirst half of 2017 given lower than normal retail replenishment. Additionally, retailers steadily reduced their run-rate inventory levels as part of increasingtheir competitiveness with online retailers. And in late 2017 many retailers were extremely conservative in their ordering which resulted in sporadic stock-outs at least for Turtle Beach given robust holiday demand. Coming into 2018, demand for gaming headsets has been very strong in North America andEurope resulting in the retailers needing to rapidly replenish. Currently, retail inventory levels are at a low but sustainable level and the Company expectssales in the near term to more closely reflect sell through.4 Business StrategyWe intend to further build upon Turtle Beach's brand awareness, superior audio technology and high-quality products to grow the core console businessas well as enter the personal computer casual gaming business to increase sales and profitability.•Continue to Advance Our Brand. We believe that our brand's image among consumers is a competitive advantage and that our success is attributable toour emphasis on delivering the highest quality, most innovative headsets.To maintain our competitive position in our markets, we are focused on the following:•continuing to deliver innovative, high quality gaming headsets that incorporate advanced audio and wireless technology; while delivering asuperior game and chat audio experience and unmatched comfort.•maintaining our strategic relationships and furthering investment in social media and eSports partnerships, which we believe provide our brand alarger presence with consumers and create opportunities for retailers to carry our products;•leveraging high-quality technical support/customer service to exceed consumer expectations and develop brand loyalty.•Expand Our Product Lines. We continue to invest in the resources necessary to maintain and expand our technical capability to manufacture multipleproduct lines that incorporate the latest technologies. In 2017, we launched an industry-first Xbox One headset that wirelessly connects directly to theconsole.•Grow Revenue in New Channels. We intend to increase our sales by continuing to develop internally, or through potential acquisitions, products thatwe offer to our customers with an enhanced focus on growth in the personal computer gaming sector. In order to meet emerging consumer habits, we willcontinue to invest in and remodel our website to drive direct sales expansion.Product DevelopmentWe continue to innovate, make improvements to our technology and develop new products, and anticipate that we will continue to devote substantialresources to research and development in the near future. Our product management team takes a disciplined approach to product design that balancesiteration, incremental improvement and innovation to achieve a blend of differentiated technology designed to attract customers, maintain product designcontinuity and exceed expectations as to quality, reliability and profitability. For the year ended December 31, 2017, we invested $5.6 million in thecontinued expansion of our new generation headset portfolio including the launch of the Recon Chat, and the Stealth 600 and Stealth 700 series. For theyears ended December 31, 2016 and 2015, we expended $8.3 million and $11.6 million, respectively, reflective of certain HyperSound investments.Intellectual PropertyWe operate in industries where innovations, investment in new ideas and protection of resulting intellectual property rights are critical to success. Wehave a substantial base of intellectual property assets to protect our current and future product development, such as key innovations in gaming headsets aswell as all of the core technology areas behind HyperSound, and intend to vigorously enforce such rights.As a third-party gaming headset company certain technology used in the new generation of consoles, such as integrated voice and chat audio from theXbox One, requires a license to enable products to connect to that platform. While Playstation®4 does not require any license to produce headsets that canconnect, certain connections on the Xbox One require the purchase of proprietary chips to integrate into the locked chat audio.While we currently believe that we have the necessary licenses, or can obtain the necessary licenses to produce compatible products, there is noguarantee that licenses will be renewed or granted. Moreover, if these licensing parties enter into exclusive license agreements with companies other than usfor their “closed systems” or if we are unable to obtain sufficient quantities of these headset adapters or chips, we would be placed at a competitivedisadvantage.Supply Chain and OperationsWe have a global network of suppliers that manufacture products to meet our cost objectives and quality standards sought by our customers. We haveworked closely with component, manufacturing and global logistic partners to build a supply chain that we consider predictable, scalable and consistent toprovide high-quality, reliable products and leading cost management5 practices. The use of outsourced manufacturing facilities is designed to take advantage of specific expertise and allow for flexibility and scalability torespond to seasonality and changing demands for our products.In anticipation of new product development and incremental growth, we made additional investments with a focus on making advancements to ourplanning systems. In connection with our initiative to improve our operating efficiency and reduce costs, we have continued efforts to focus on company-wide overhead reduction activities including right-sizing our supply chain, consolidation of warehouses with our global logistics partnership with Keuhne &Nagel and transitioned our European warehouse to a third-party logistics provider.We believe we have solid relationships with our suppliers and that, subject to the discussion in “Risk Factors” and “Management’s Discussion andAnalysis of Financial Condition and Results of Operations - Liquidity and Capital Resources,” we will continue to have a sufficient supply of qualityproducts on satisfactory terms.Retail DistributionOur headsets are sold in over 40 countries, by retailers such as Amazon, Best Buy, Game, GameStop, EB Games, Target, and Walmart. We often have abroader assortment and more shelf space than competitors at video game and electronics retailers such as GameStop and Best Buy, which we believereinforces the brand’s authenticity with gaming enthusiasts, and our presence in mass channel retailers such as Walmart and Target enables the brand to reacha wider audience of casual gamers. Our established presence on Amazon.com and other online retail sites, and positive consumer product ratings on thosesites, increases the search visibility of our products and helps to influence both online and in-store sales.Turtle Beach Europe serves as a primary sales office for the European market, and has strengthened our international operations with support for sales,marketing, customer service and distribution.TurtleBeach.com is an important focal point for our marketing efforts serving as a destination for paid and earned media. Earned media is favorablepublicity gained through promotional efforts other than advertising, as compared with paid media, which refers to publicity gained through advertising. Thewebsite acts as a hub for both online and offline activity, and provides a direct sales channel for new and refurbished products.CustomersThe following tables show net revenues by product type: December 31, 2017 2016 2015Net Revenues (in thousands)Headset $148,828 $173,323 $161,835HyperSound 307 655 912Total $149,135 $173,978 $162,747The Headset business customer base is comprised primarily of large retailers and distributors, both domestic and international. In 2017, net sales to ourmajor market channels consisted of $89.7 million to North American retail customers, $41.4 million to European customers, $9.8 million to North Americandistributors and $7.9 million to other customers.Our three largest individual customers accounted for approximately 43% of our gross sales in 2017, 49% of our gross sales in 2016 and 47% of ourgross sales in 2015. During 2017, our three largest customers, Best Buy, Walmart and Game Stop, each accounted for between 13% to 16% of ourconsolidated net sales.Geographic InformationIn addition to the traditional markets of the United States and United Kingdom, we have pursued growth in countries such as Germany and France andbelieve that additional long-term growth opportunities exist in Asia Pacific and Latin America.During 2016, we began to improve our international structure by taking retailers across Europe direct, leveraging off our new warehousing facility andsimplifying our distribution model to provide less risk and lower infrastructure costs. In 2017, the Company gained market share in most of our majorEuropean markets, particularly in the United Kingdom.6 The following table presents total net revenues, and percentage of total, based on where customers are physically located for each of the three yearsended December 31, 2017: 2017 2016 2015 (in thousands) North America$103,15969.2% $130,37174.9% $117,52672.2%United Kingdom21,11314.2% 21,77812.5% 20,88112.8%Europe20,27713.6% 15,7299.0% 17,32910.6%Other4,5863.0% 6,1003.6% 7,0114.4%Total revenues$149,135 $173,978 $162,747 Long-lived assets are largely held in the United States, refer to Note 12, “Geographic Information” in the Notes to the Consolidated FinancialStatements.SeasonalityOur gaming headset business is seasonal with a significant portion of sales and profits typically occurring around the holiday period. Historically, morethan 45% of headset business revenues are generated during the period from September through December as new headsets are introduced and consumersengage in holiday shopping. In addition, launches of major new online multiplayer games and specific retailer purchasing behavior can drive significantrevenue shifts between months and quarters in a given year.EmployeesAs of December 31, 2017, Turtle Beach had 135 employees, of which 116 were full-time salaried employees. None of our employees are represented bya labor union. We believe that our relationship with our employees is good.Available InformationWe make available free of charge on or through our website, http://corp.turtlebeach.com, our Annual Report on Form 10-K, Quarterly Reports on Form10-Q, Current Reports on Form 8-K, and all amendments to those reports as soon as reasonably practicable after such material is electronically filed with orfurnished to the Securities and Exchange Commission.

Our business, financial condition, operating results and cash flows can be affected by a number of factors, whether currently known orunknown, including but not limited to those described below, any one or more of which could, directly or indirectly, cause the Company’s actual results ofoperations and financial condition to vary materially from past, or from anticipated future, results of operations and financial condition. Any of thesefactors, in whole or in part, could materially and adversely affect the Company’s business, financial condition, results of operations, cash flows andcommon stock price. Additional risks and uncertainties not presently known to us or that we currently consider immaterial may also impair our businessoperations.Because of the following factors, as well as other factors affecting the Company’s financial condition and operating results, past financialperformance should not be considered to be a reliable indicator of future performance, and investors should not use historical trends to anticipate resultsor trends in future periods. Please also see “Statement Regarding Forward-Looking Disclosures” in the section immediately preceding Item 1 of this Report.Risks Related to LiquidityWe depend upon the availability of capital under our revolving credit facility and term loan to finance our operations. Any additional financing that wemay need may not be available on favorable terms or at all.In addition to cash flow generated from operations, we finance our operations with a revolving credit facility (the “Credit Facility”) provided by Bankof America, as Agent, Sole Lead Arranger and Sole Bookrunner and our term loan (the “Term Loan Due 2019”) provided by Crystal Financial LLC(“Crystal”), as Agent, Sole Lead Arranger and Sole Bookrunner. If we are unable to comply with the financial and other covenants contained in the CreditFacility or the Term Loan Due 2019 (collectively, the “Loan Documents”) and are unable to obtain a waiver under the applicable Loan Documents, Bank ofAmerica or Crystal, as applicable, may declare the outstanding borrowings under the applicable Loan Documents immediately due and payable. Such anevent would have an immediate and material adverse impact on our business, results of operations and financial condition. We would be required to obtainadditional financing from other sources, and we cannot predict whether or on what terms, if any, additional financing might be available. If we are required toseek additional financing and are unable to obtain it, we may have to change our business and capital expenditure plans, which may have a materiallyadverse effect on our business, financial condition and results of operations. In addition, the debt under the Loan Documents could make it more difficult toobtain other debt financing in the future, which could put us at a competitive disadvantage to competitors with less debt.The Loan Documents contain financial and other covenants that we are obligated to maintain. If we violate any of these covenants, we will be in defaultunder the applicable Loan Documents. These covenants include restrictions that prohibit or otherwise limit our ability to pay dividends, incur additionalindebtedness, acquire assets or engage in certain other types of transactions, and also require that we maintain certain financial ratios and EBITDA levelsduring specified periods. If a default occurs and is not timely cured or waived, Bank of America or Crystal, as applicable, could seek remedies against us,including termination or suspension of obligations to make loans and issue letters of credit and acceleration of amounts due under the applicable LoanDocuments. No assurance can be given that we will be able to maintain compliance with these covenants in the future. The Credit Facility is asset based andcan only be drawn down in an amount to which eligible collateral exists and can be negatively impacted by extended collection of accounts receivable,unexpectedly high product returns and slow moving inventory, among other factors. As of the date of this Report, we were in compliance with our covenantsunder the Loan Documents.The Credit Facility and Term Loans provide our lenders with a first-priority lien against substantially all of our working capital assets, including tradeaccounts receivable, inventories, and intellectual property and contains certain restrictions on our ability to take certain actions.The Credit Facility and Term Loan Due 2019 contain certain financial covenants and other restrictions that limit our ability, among other things, toincur certain additional indebtedness; pay dividends and repurchase stock; make certain investments and other payments; enter into certain mergers orconsolidations; engage in sale and leaseback transactions and transactions with affiliates; and encumber and dispose of assets.In addition, we have granted the lenders a first-priority lien against substantially all of our assets, including trade accounts receivable, inventories andour intellectual property. Failure to comply with the operating restrictions or financial covenants could result in a default which could cause the lenders toaccelerate the timing of payments and exercise their lien on substantially all of our assets.8 If suppliers, customers, landlords, employees or other stakeholders lose confidence in our business, it may be more difficult for us to operate and maymaterially adversely affect our business, results of operations and financial condition.If suppliers, customers, landlords, employees or other stakeholders have doubts regarding our ability to continue as a going concern, this could result infurther loss of confidence, which, in turn, could materially adversely affect our ability to operate. Concerns about our financial condition may cause oursuppliers and other counterparties to tighten credit terms or cease doing business with us altogether, which would have a material adverse effect on ourbusiness and results of operations.Risks Related to Our OperationsWe depend upon the success and availability of third-party gaming platforms and software to drive sales of our headset products.The performance of our headset business is affected by the continued success of third-party gaming platforms, such as Microsoft's Xbox consoles andSony's PlayStation® consoles, as well as video games developed by such manufacturers and other third-party publishers. Our business could suffer if any ofthese parties fail to continue to drive the success of these platforms, develop new or enhanced videogame platforms, develop popular game and entertainmenttitles for current or future generation platforms or produce and timely release sufficient quantities of such consoles. For example, DFC Intelligence forecasts'estimates of future cumulative new generation console has declined since the debut of the new-gen consoles in 2013, which, if such estimates are accurate,may negatively impact our future headset sales or otherwise negatively impact our business. Further, if a platform is withdrawn from the market or fails to sell,we may be forced to liquidate inventories relating to that platform or accept returns resulting in significant losses.In order for certain of our headsets to connect to the Xbox One advanced features and controls, a proprietary computer chip or wireless module isrequired. As a result, with respect to our products designed for the Xbox One, we are currently reliant on Microsoft or their designated supplier to provide uswith sufficient quantities. If we are unable to obtain sufficient quantities of these headset adapters or chips, sales of such Xbox One headsets andconsequently our revenues would be adversely affected.In addition, we are licensed and approved by Microsoft to develop and sell Xbox One compatible audio products pursuant to a license agreement underwhich we have the right to manufacture (including through third party manufacturers), market and sell audio products for the Xbox One video game console(the “Xbox One Agreement”). Our Xbox One headsets are dependent on this license. Microsoft has the right to terminate the Xbox One Agreement undercertain circumstances set forth in the agreement. Should the Xbox One Agreement be terminated, our headset offerings may be limited, thereby significantlyreducing our revenues.Accordingly, Microsoft, Sony and other third-party gaming platform manufacturers may control our ability to manufacture headsets compatible withtheir platforms, and could cause unanticipated delays in the release of our products as well as increases to projected development, manufacturing, licensing,marketing or distribution costs, any of which could negatively impact our business.Our Turtle Beach brand faces significant competition from other consumer electronics companies and this competition could have a material adverseeffect on our financial condition and results of operations.We compete with other producers of personal computers and video game console headsets, including the video game console manufacturers. Ourcompetitors may spend more money and time on developing and testing products, undertake more extensive marketing campaigns, adopt more aggressivepricing policies, pay higher fees to licensors for motion picture, television, sports, music and character properties, or develop more commercially successfulproducts for the personal computer or video game platforms than we do. In addition, competitors with large product lines and popular products, in particularthe video game console manufacturers, typically have greater leverage with retailers, distributors and other customers, who may be willing to promoteproducts with less consumer appeal in return for access to those competitors’ more popular products.In the event that a competitor reduces prices, we could be forced to respond by lowering our prices to remain competitive. If we are forced to lowerprices, we may be required to “price protect” products that remain unsold in our customers’ inventories at the time of the price reduction. Price protectionresults in our issuing a credit to our customers in the amount of the price reduction for each unsold unit in that customer’s inventory. Our price protectionpolicies, which are customary in the industry, can have a major impact on our sales and profitability.In addition, if console manufacturers implement new technologies, through hardware or software, which would cause our headsets to becomeincompatible with that hardware manufacturer’s console, there could be unanticipated delays in the release of our products as well as increases to projecteddevelopment, manufacturing, marketing or distribution costs, any of which could harm our business and financial results.9 Further, new and emerging technologies and alternate platforms for gaming, such as mobile devices and virtual reality devices, could make the consolesfor which our headsets are designed less attractive or, in time, obsolete, which could require us to transition our business model such as develop products forother gaming platforms. The industries in which we operate are subject to competition in an environment of rapid technological change, and if we do not adapt to, andappropriately allocate our resources among, emerging technologies, our revenues could be negatively affected.We must make substantial product development and other investments to align our product portfolio and development efforts in response to marketchanges in the gaming industry. We must anticipate and adapt our products to emerging technologies in order to keep those products competitive. When wechoose to incorporate a new technology into our products or to develop a product for a new platform or operating system, we are often required to make asubstantial investment prior to the introduction of the product. If we invest in the development of a new technology or for a new platform that does notachieve significant commercial success, our revenues from those products likely will be lower than anticipated and may not cover our costs.Further, our competitors may adapt to an emerging technology more quickly or effectively than we do, creating products that are technologicallysuperior to ours, more appealing to consumers, or both. If, on the other hand, we elect not to pursue the development of products incorporating a newtechnology or for new platforms that achieve significant commercial success, our revenues could also be adversely affected. It may take significant time andresources to shift product development resources to that technology or platform and it may be more difficult to compete against existing productsincorporating that technology or for that platform. Any failure to successfully adapt to, and appropriately allocate resources among, emerging technologiescould harm our competitive position, reduce our share and significantly increase the time it takes us to bring popular products to market.There are numerous steps required to develop a product from conception to commercial introduction and to ensure timely shipment to retail customers,including designing, sourcing and testing the electronic components, receiving approval of hardware and other third-party licensors, factory availability andmanufacturing and designing the graphics and packaging. Any difficulties or delays in the product development process will likely result in delays in thecontemplated product introduction schedule. It is common in new product introductions or product updates to encounter technical and other difficultiesaffecting manufacturing efficiency and, at times, the ability to manufacture the product at all. Although these difficulties can be corrected or improved overtime with continued manufacturing experience and engineering efforts, if one or more aspects necessary for the introduction of products are not completed asscheduled, or if technical difficulties take longer than anticipated to overcome, the product introductions will be delayed, or in some cases may beterminated. No assurances can be given that our products will be introduced in a timely fashion, and if new products are delayed, our sales and revenuegrowth may be limited or impaired.Our business could be adversely affected by significant movements in foreign currency exchange rates.We are exposed to fluctuations in foreign currency transaction exchange rates, particularly with respect to the Euro and British Pound. Any significantchange in the value of currencies of the countries in which we do business relative to the value of the U.S. dollar could affect our ability to sell productscompetitively and control our cost structure. Additionally, we are subject to foreign exchange translation risk due to changes in the value of foreigncurrencies in relation to our reporting currency, the U.S. dollar. The translation risk is primarily concentrated in the exchange rate between the U.S. dollar andthe British Pound. As the U.S. dollar fluctuates against other currencies in which we transact business, revenue and income can be impacted.A significant portion of our revenue is derived from a few large customers, and the loss of any such customer, or a significant reduction in purchases bysuch customer, could have a material adverse effect on our business, financial condition and results of operations.During 2017, our three largest individual customers accounted for approximately 43% of our gross sales in the aggregate. The loss of, or financialdifficulties experienced by, any of these or any of our other significant customers, including as a result of the bankruptcy of a customer, could have a materialadverse effect on our business, results of operations, financial condition and liquidity. We do not have long-term agreements with these or other significantcustomers and our agreements with these customers do not require them to purchase any specific amount of products. All of our customers generally purchasefrom us on a purchase order basis. As a result, agreements with respect to pricing, returns, cooperative advertising or special promotions, among other things,are subject to periodic negotiation with each customer. No assurance can be given that these or other customers will continue to do business with us or thatthey will maintain their historical levels of business. In addition, the uncertainty of product orders can make it difficult to forecast our sales and allocate ourresources in a manner consistent with actual sales, and our expense levels are based in part on our expectations of future sales. If our expectations regardingfuture10 sales are inaccurate, we may be unable to reduce costs in a timely manner to adjust for sales shortfalls. In addition, financial difficulties experienced by asignificant customer could increase our exposure to uncollectible receivables and the risk that losses from uncollected receivables exceed the reserves wehave set aside in anticipation of this risk.The manufacture, supply and shipment of our products are dependent upon a limited number of third parties, and our success is dependent upon the abilityof these parties to manufacture, supply and ship sufficient quantities of their product components to us in a timely fashion, as well as the continuedviability and financial stability of these third-parties.Because we rely on a limited number of manufacturers and suppliers for our products, we may be materially and adversely affected by the failure of anyof those manufacturers and suppliers to perform as expected or supply us with sufficient quantities of their product components to ensure consumeravailability of our own products. Our suppliers’ ability to supply products to us is also subject to a number of risks, including the availability of rawmaterials, their financial instability, the destruction of their facilities, or work stoppages. Any shortage of raw materials or components or an inability tocontrol costs associated with manufacturing could increase our costs or impair our ability to ship orders in a timely and cost-efficient manner. As a result, wecould experience cancellations of orders, refusal to accept deliveries or a reduction in our prices and margins, any of which could harm our financialperformance and results of operations.Moreover, there can be no assurance that such manufacturers and suppliers will not refuse to supply us at prices we deem acceptable, independentlymarket their own competing products in the future, or otherwise discontinue their relationships with or support of us. Our failure to maintain these existingmanufacturing and supplier relationships, or to establish new relationships on similar terms in the future, could have a material adverse effect on our business,results of operations, financial condition and liquidity.In particular, certain of our products have a number of components and subassemblies produced by outside suppliers. In addition, for certain of theseitems, we qualify only a single source of supply with long lead times, which can magnify the risk of shortages or result in excess supply and also decreasesour ability to negotiate price with our suppliers. Also, if we experience quality problems with suppliers, then our production schedules could be significantlydelayed or costs significantly increased, which could have an adverse effect on our business, liquidity, results of operation and financial position.In addition, the ongoing effectiveness of our supply chain is dependent on the timely performance of services by third parties shipping products andmaterials to and from our warehouse facilities and other locations. If we encounter problems with these shipments, our ability to meet retailer expectations,manage inventory, complete sales and achieve objectives for operating efficiencies could be materially adversely affected. We have experienced some ofthese problems in the past and we cannot assure you that we will not experience similar problems in the future. Our net sales and operating income fluctuate on a seasonal basis and decreases in sales or margins during peak seasons could have a disproportionateeffect on our overall financial condition and results of operations.Historically, a majority of our annual revenues have been generated during the holiday season of September to December. If we do not accuratelyforecast demand for particular products, we could incur additional costs or experience manufacturing delays. Any shortfall in net sales during this periodwould cause our annual results of operations to suffer significantly.Demand for our products depends on many factors such as consumer preferences and the introduction or adoption of game platforms and relatedcontent, and can be difficult to forecast. If we misjudge the demand for our products, we could face the following problems in our operations, each of whichcould harm our operating results:•If our forecasts of demand for products are too high, we may accumulate excess inventories of products, which could lead to markdown allowancesor write-offs affecting some or all of such excess inventories. We may also have to adjust the prices of our existing products to reduce such excessinventories;•If demand for specific products increases beyond what we forecast, our suppliers and third-party manufacturers may not be able to increaseproduction quickly enough to meet the demand. Our failure to meet market demand may lead to missed opportunities to increase our base of gamers,damage our relationships with retailers or harm our business;•The on-going console transition increases the likelihood that we could fail to accurately forecast demand for our new generation console headsetsand our existing headsets; and•Rapid increases in production levels to meet unanticipated demand could result in increased manufacturing errors, as well as higher component,manufacturing and shipping costs, all of which could reduce our profit margins and harm our relationships with retailers and consumers.11 Loss of our key management and other personnel could impact our business.Our future success depends largely upon the continued service of our executive officers and other key management and technical personnel and on ourability to continue to attract, retain and motivate qualified personnel. In addition, competition for skilled and non-skilled employees among companies likeours is intense, and the loss of skilled or non-skilled employees or an inability to attract, retain and motivate additional skilled and non-skilled employeesrequired for the operation and expansion of our business could hinder our ability to conduct research activities successfully, develop new products, attractcustomers and meet customer shipments.If we are unable to continue to develop innovative and popular headset products, or if our design and marketing efforts do not effectively raise therecognition and reputation of our Turtle Beach brand, we may not be able to successfully implement our headset growth strategy.We believe that our ability to extend the recognition and favorable perception of our Turtle Beach brand is critical to implement our headset growthstrategy, which includes further establishing our position in existing gaming headsets, developing a strong position in new console headsets, expandingbeyond existing console, PC and mobile applications to new technology applications, accelerating our international growth and expanding complementaryproduct categories. To extend the reach of our Turtle Beach brand, we believe we must devote significant time and resources to headset product design,marketing and promotions. These expenditures, however, may not result in a sufficient increase in net sales to cover such costs.Future transitions in console platforms may adversely affect our headset business.When new console platforms are announced or introduced into the market, consumers have historically reduced their purchases of game consoleperipherals and accessories, including headsets, for old generation console platforms in anticipation of new platforms becoming available. During theseconsole transition periods, sales of gaming console headsets such as those sold by us, related to old generation consoles slow or decline until new platformsare introduced and achieve wide consumer acceptance, which we cannot guarantee. This decrease or decline may not be offset by increased sales of productsfor the new console platforms. Over time as the old generation platform user base declines, products for the old platforms are typically discontinued whichcan result in lower margins, excess inventory, excess parts, or similar costs related to end of life of a product model. In addition, as a third party gamingheadset company, we are reliant on working with the console manufacturers for our headsets to be compatible with any new console platforms, which if notdone on a timely basis may adversely affect sales. Sony and Microsoft may make changes to their platforms that impact how headset connect with or workwith the new consoles which could create a disruption to consumer buying behavior and/or product life-cycles.As console hardware moves through its life cycle, hardware manufacturers typically enact price reductions, and decreasing prices may put downwardpressure on prices for products for such platforms. During platform transitions, we may simultaneously incur costs both in continuing to develop and marketnew products for prior-generation video game platforms, which may not sell at premium prices, and also in developing products for current-generationplatforms, which will not generate immediate or near-term revenue. As a result, our operating results during platform transitions are more volatile and moredifficult to predict than during other times.Further, technological and other developments may in the future accelerate the frequency of such console transitions resulting in such disruptionoccurring more frequently. For example, Sony and Microsoft have announced hardware upgrades to the current console generations with the PS®4 Pro andXbox One X, respectively. In addition, competing technologies such as tablet-based gaming and virtual reality may result in further disruption to the overallconsole gaming market.We are party to ongoing stockholder litigation, and in the future could be party to additional stockholder litigation, any of which could harm our business,financial condition and operating results.We have had, and may continue to have, actions brought against us by stockholders in connection with the merger, past transactions, changes in ourstock price or other matters. Any such claims, whether or not resolved in our favor, could divert our management and other resources from the operation of ourbusiness and otherwise result in unexpected and substantial expenses that would adversely and materially impact our business, financial condition andoperating results. For example, and as further described in Item 3, “Legal Proceedings,” and Note 13, “Commitments and Contingencies,” we are involved inlegal proceedings related to the merger of VTBH and Paris Acquisition Corp. involving certain of our stockholders, including the holder of VTBH’s Series BRedeemable Preferred Stock, (the “Series B Holder”), filing a complaint in New York state court alleging breach of contract against VTBH and seeking adeclaratory judgment that he is entitled to damages and specific performance, including the redemption of his stock. The redemption value of VTBH’s SeriesB Redeemable Preferred Stock was $18.9 million as of December 31, 2017.12 If we are unable to protect our information systems against service interruption, misappropriation of data or breaches of security, our operations could bedisrupted, our reputation may be damaged, and we may be financially liable for damages.We rely heavily on information systems to manage our operations, including a full range of retail, financial, sourcing and merchandising systems. Weregularly make investments to upgrade, enhance or replace these systems, as well as leverage new technologies to support our growth strategies. In addition,we have implemented enterprise-wide initiatives that are intended to standardize business processes and optimize performance. Any delays or difficulties intransitioning to new systems or integrating them with current systems or the failure to implement our initiatives in an orderly and timely fashion could resultin additional investment of time and resources, which could impair our ability to improve existing operations and support future growth, and ultimately havea material adverse effect on our business.The reliability and capacity of our information systems are critical. Despite preventative efforts, our systems are vulnerable from time-to-time to damageor interruption from, among other things, natural disasters, technical malfunctions, inadequate systems capacity, human error, power outages, computerviruses and security breaches. Any disruptions affecting our information systems could have a material adverse impact on our business. In addition, anyfailure to maintain adequate system security controls to protect our computer assets and sensitive data, including associate and client data, from unauthorizedaccess, disclosure or use could damage our reputation with our associates and our clients, exposing us to financial liability, legal proceedings (such as classaction lawsuits), and regulatory action. While we have implemented measures to prevent security breaches and cyber incidents, our preventative measuresand incident response efforts may not be entirely effective. As a result, we may not be able to immediately detect any security breaches, which may increasethe losses that we would suffer. Finally, our ability to continue to operate our business without significant interruption in the event of a disaster or otherdisruption depends, in part, on the ability of our information systems to operate in accordance with our disaster recovery and business continuity plans.Our reliance on information systems and other technology also gives rise to cybersecurity risks, including security breach, espionage, systemdisruption, theft and inadvertent release of information. The occurrence of any of these events could compromise our networks, and the information storedthere could be accessed, publicly disclosed, lost or stolen. Any such access, disclosure or other loss of information could result in legal claims or proceedings,liability or regulatory penalties under laws protecting the privacy of personal information, disrupt operations, and damage our reputation, which couldadversely affect our business. In addition, as security threats continue to evolve we may need to invest additional resources to protect the security of oursystems.Our results of operations and financial condition may be adversely affected by global business, political, operational, financial and economic conditions.We face business, political, operational, financial and economic risks inherent in international business, many of which are beyond our control,including:•trade restrictions, higher tariffs, currency fluctuations or the imposition of additional regulations relating to import or export of our products,especially in China, where all of our Turtle Beach products are manufactured, which could force us to seek alternate manufacturing sources orincrease our costs;•difficulties obtaining domestic and foreign export, import and other governmental approvals, permits and licenses, and compliance with foreignlaws, which could halt, interrupt or delay our operations if we cannot obtain such approvals, permits and licenses;•difficulties encountered by our international distributors or us in staffing and managing foreign operations or international sales, including higherlabor costs;•transportation delays and difficulties of managing international distribution channels;•longer payment cycles for, and greater difficulty collecting, accounts receivable;•political and economic instability, including wars, terrorism, political unrest, boycotts, curtailment of trade and other business restrictions, any ofwhich could materially and adversely affect our net sales and results of operations; and•natural disasters.Any of these factors could reduce our net sales, decrease our gross margins, increase our expenses or reduce our profitability. Should we establish ourown operations in international territories where we currently utilize a distributor, we will become subject to greater risks associated with operating outside ofthe United States.The electronics industry in general has historically been characterized by a high degree of volatility and is subject to substantial and unpredictablevariations resulting from changing business cycles. Our operating results will be subject to fluctuations based on general economic conditions, in particularconditions that impact discretionary consumer spending. The audio products sector of the electronics industry has and may continue to experience aslowdown in sales, which adversely13 impacts our ability to generate revenues and impacts the results of our future operations. A lack of available credit in financial markets may adversely affectthe ability of our commercial customers to finance purchases and operations and could result in an absence of orders or spending for our products as well ascreate supplier disruptions. We are unable to predict the likely duration and severity of any adverse economic conditions and disruptions in financial marketsand the effects they will have on our business and its financial condition.Further, Turtle Beach products are manufactured in China for export to the United States and worldwide. As a result of opposition to policies of theChinese government and China’s growing trade surpluses with the United States, there has been, and in the future may be, opposition to the extension ofnormal trade relations (“NTR”) status for China. The loss of NTR status for China, changes in current tariff structures or adoption in the United States of othertrade policies adverse to China could increase our manufacturing expenses and make it more difficult for us to manufacture our products in China.If we fail to maintain an effective system of internal controls, we may not be able to accurately report financial results or prevent fraud, which could havean adverse effect on our business and financial condition.Effective internal controls are necessary to provide reliable financial reports and to assist in the effective prevention of fraud. Any inability to providereliable financial reports or prevent fraud could harm our business. The Sarbanes-Oxley Act requires, among other things, that we evaluate our systems andprocesses and test our internal controls over financial reporting to allow management and our independent registered public accounting firm, as applicable,to report on the effectiveness of our internal control over financial reporting. If we are not able to comply with the requirements of Section 404 of theSarbanes-Oxley Act, or if we or our independent registered public accounting firm identifies deficiencies in our internal control over financial reporting thatare deemed to be material weaknesses, investors could lose confidence in the accuracy and completeness of our financial reports, the market price of ourcommon stock could decline and we could be subject to sanctions, investigations by the Nasdaq Stock Market, LLC (“NASDAQ”), the SEC or otherregulatory authorities, or shareholder litigation.In addition, failure to maintain effective internal controls could result in financial statements that do not accurately reflect our financial condition orresults of operations. There can be no assurance that we will be able to maintain a system of internal controls that fully complies with the requirements of theSarbanes-Oxley Act of 2002 or that our management and independent registered public accounting firm will continue to conclude that our internal controlsare effective.We carried out an evaluation, under the supervision of our Chief Executive Officer (our principal executive officer, or PEO) and our Chief FinancialOfficer (our principal financial officer, or PFO), of the effectiveness of the design and operation of our disclosure controls and procedures. Based upon thatevaluation, our PEO and PFO concluded that our disclosure controls and procedures, as defined in Rule 13a-15(e) of the Exchange Act, were effective as ofDecember 31, 2017. However, because of the inherent limitations of internal control over financial reporting, including the possibility of collusion orimproper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Accordingly,even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Also, projections of anyevaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may becomeinadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.The affirmative vote in the United Kingdom to withdraw from the European Union may adversely affect our business.On June 23, 2016, the United Kingdom ("UK") held a referendum in which voters approved a potential exit from the European Union ("EU"), commonlyreferred to as "Brexit." As a result of the referendum, the UK is expected to exit the EU in March 2019. The Brexit vote, and the UK's expected exit from theEU, may result in regulatory uncertainty throughout the region and could adversely affect business activity, political stability and economic conditions inthe UK, the Eurozone, the EU and elsewhere. Any of these developments could have a material adverse effect on business activity in the UK, the Eurozone, orthe EU.The uncertainty concerning terms of the exit could also have a negative impact on the growth of the UK and/or EU economies and cause greatervolatility in the pound sterling, euro and/or other currencies.Risks Related to our Intellectual Property and other Legal and Regulatory MattersOur competitive position will be seriously damaged if our products are found to infringe on the intellectual property rights of others.Other companies and our competitors may currently own or obtain patents or other proprietary rights that might prevent, limit or interfere with ourability to make, use or sell our products. Although we do not believe that our products infringe the proprietary rights of any third parties, there can be noassurance that infringement or other legal claims will not be asserted14 against us or that we will not be found to infringe the intellectual property rights of others. The electronics industry is characterized by vigorous protectionand pursuit of intellectual property rights or positions, resulting in significant and often protracted and expensive litigation. In the event of a successful claimof infringement against us and our failure or inability to license the infringed technology, our business and operating results could be adversely affected. Anylitigation or claims, whether or not valid, could result in substantial costs or a diversion of our resources. An adverse result from intellectual propertylitigation could force us to do one or more of the following:•cease selling, incorporating or using products or services that incorporate the challenged intellectual property;•obtain a license from the holder of the infringed intellectual property right, which license may not be available on reasonable terms, if at all; and/or•redesign products or services that incorporate the disputed technology.If we are forced to take any of the foregoing actions, we could face substantial costs and shipment delays and our business could be seriously harmed.Although we carry general liability insurance, our insurance may not cover potential claims of this type or may be inadequate to insure us for all liability thatmay be imposed.In addition, it is possible that our customers or end users may seek indemnity from us in the event that our products are found or alleged to infringe theintellectual property rights of others. Any such claim for indemnity could result in substantial expenses to us that could harm our operating results.If we are unable to obtain and maintain intellectual property rights and/or enforce those rights against third parties who are violating those rights, ourbusiness could suffer.We rely on various intellectual property rights, including patents, trademarks, trade secrets and trade dress to protect our Turtle Beach brand name,reputation, product appearance and technology and our proprietary rights in our HyperSound technology. Although we have entered into confidentiality andinvention assignment agreements with our employees and contractors, and nondisclosure agreements with selected parties with whom we conduct business tolimit access to and disclosure of our proprietary information, these contractual arrangements and the other steps we have taken to protect our intellectualproperty may not prevent misappropriation of that intellectual property or deter independent third-party development of similar technologies. Monitoringthe unauthorized use of proprietary technology and trademarks is costly, and any dispute or other litigation, regardless of outcome, may be costly and timeconsuming and may divert the attention of management and key personnel from our business operations. The steps taken by us may not prevent unauthorizeduse of proprietary technology or trademarks. Many features of our products are not protected by patents; and as a consequence, we may not have the legalright to prevent others from reverse engineering or otherwise copying and using these features in competitive products. If we fail to protect or to enforce ourintellectual property rights successfully, our competitive position could suffer, which could adversely affect our financial results.We are susceptible to counterfeiting of our products, which may harm our reputation for producing high-quality products and force us to incur expensesin enforcing our intellectual property rights. Such claims and lawsuits can be expensive to resolve, require substantial management time and resources, andmay not provide a satisfactory or timely result, any of which may harm our results of operations. As some of our products are sold internationally, we are alsodependent on the laws of a range of countries to protect and enforce our intellectual property rights. These laws may not protect intellectual property rights tothe same extent or in the same manner as the laws of the United States.Further, we are party to licenses that grant us rights to intellectual property, including trademarks, which are necessary or useful to our Turtle Beachbusiness. One or more of our licensors may allege that we have breached our license agreement with them, and seek to terminate our license. If successful, thiscould result in our loss of the right to use the licensed intellectual property, which could adversely affect our ability to commercialize our technologies orproducts, as well as harm our competitive business position and our business prospects.Our success also depends in part on our ability to obtain and enforce intellectual property protection of our technology, particularly our patents. Thereis no guarantee any patent be granted on any patent application that we have filed or may file. Claims allowed from existing or pending patents may not be ofsufficient scope or strength to protect the economic value of our technologies. Further, any patent that we may obtain will expire, and it is possible that itmay be challenged, invalidated or circumvented.We may initiate claims or litigation against third parties in the future for infringement of our proprietary rights or to determine the scope and validity ofour proprietary rights or the proprietary rights of our competitors. These claims could result in costly litigation and divert the efforts of our technical andmanagement personnel. As a result, our operating results could suffer and our financial condition could be harmed.15 We are dependent upon third-party intellectual property to manufacture some of our products.The performance of certain technology used in new generation consoles, such as integrated voice and chat audio from the Xbox One, is improved by alicensed component to ensure compatibility with our products.While we currently believe that we have the necessary licenses, or can obtain the necessary licenses, in order to produce compatible products, there isno guarantee that our licenses will be renewed or granted in the first instance. Moreover, if these first parties enter into license agreements with companiesother than us for their “closed systems” or if we are unable to obtain sufficient quantities of these headset adapters or chips, we would be placed at acompetitive disadvantage.Our products may be subject to warranty claims, product liability and product recalls.We may be subject to product liability or warranty claims that could result in significant direct or indirect costs, or we could experience greater returnsfrom retailers than expected, which could harm our net sales. The occurrence of any quality problems due to defects in our products could make us liable fordamages and warranty claims in excess of any existing reserves. In addition to the risk of direct costs to correct any defects, warranty claims, product recalls orother problems, any negative publicity related to the perceived quality of our products could also affect our brand image, decrease retailer and distributordemand and our operating results and financial condition could be adversely affected.We could incur unanticipated expenses in connection with warranty or product liability claims relating to a recall of one or more of our products, whichcould require significant expenditures to defend. Additionally, we may be required to comply with governmental requirements to remedy the defect and/ornotify consumers of the problem that could lead to unanticipated expense, and possible product liability litigation against a customer or us. As ofDecember 31, 2017 and the date of this Report, the Company has not received notice of any lawsuits against the Company in connection with any recallactions.Changes in laws or regulations or the manner of their interpretation or enforcement could adversely impact our financial performance and restrict ourability to operate our business or execute our strategies.New laws or regulations, or changes in existing laws or regulations or the manner of their interpretation or enforcement, may create uncertainty forpublic companies, increase our cost of doing business and restrict our ability to operate our business or execute our strategies. This could include, amongother things, compliance costs and enforcement under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”). Forexample, under Section 1502 of the Dodd-Frank Act, the SEC has adopted additional disclosure requirements related to the source of certain “conflictminerals” for issuers for which such “conflict minerals” are necessary to the functionality or production of a product manufactured, or contracted to bemanufactured, by that issuer. The metals covered by the rules include tin, tantalum, tungsten and gold. Our suppliers may use some or all of these materials intheir production processes. The rules require us to conduct a reasonable country of origin inquiry to determine if we know or have reason to believe any ofthe minerals used in the production process may have originated from the Democratic Republic of the Congo or an adjoining country. If we are not able todetermine the minerals did not originate from a covered country or conclude that there is no reason to believe that the minerals used in the productionprocess may have originated in a covered country, we would be required to perform supply chain due diligence on members of our supply chain. Globalsupply chains can have multiple layers, thus the costs of complying with these new requirements could be substantial. These new requirements may alsoreduce the number of suppliers who provide conflict free metals, and may affect our ability to obtain products in sufficient quantities or at competitive prices.Compliance costs such as these could have a material adverse effect on our results of operations.We continually evaluate and monitor developments with respect to new and proposed laws, regulations, standards and rules and cannot predict orestimate the amount of the additional costs we may incur or the timing of such costs. Any such new or changed laws, regulations, standards and rules may besubject to varying interpretations and as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governingbodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure andgovernance practices. We are committed to maintaining high standards of corporate governance and public disclosure. If our efforts to comply with new orchanged laws, regulations and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to practice,regulatory authorities may initiate legal proceedings against us and we may be harmed.The current administration has called for substantial change to fiscal and tax policies, which include comprehensive tax reform and may includechanges to the implementation of the Dodd-Frank Act and related or similar regulations. The “Tax Cuts and Jobs Act,”enacted in December 2017, reduces theU.S. federal corporate tax rate from 35% to 21% effective January 1, 2018. We cannot predict whether in total we benefit from, or are negatively affected by,the changes.16 Our HyperSound technology is subject to government regulation, which could lead to unanticipated expenses and/or enforcement action against us.Under the Radiation Control for Health and Safety Act of 1968, and the associated regulations promulgated by the Food and Drug Administration(“FDA”), HyperSound products are regulated as electrical emitters of ultrasonic vibrations. Under the terms of such regulations, in August 2012 we provided,and in January 2016 further supplemented, an abbreviated report to the FDA describing the HyperSound commercial product. In September 2015 weprovided an initial product report describing the HyperSound Clear® 500P product. The FDA may respond to these reports and request changes or safeguardsto our HyperSound products, but it has not done so to date. We also are required to notify the FDA in writing should a product be found to have a defectrelating to safety of use due to the emission of electronic product radiation. We do not believe our technology poses any human health risks. However, it ispossible that we, or one of our customers, could be required to modify the technology, or a product incorporating the technology, to comply withrequirements that may be imposed by the FDA. Our HyperSound product advertising is regulated by the Federal Trade Commission (the “FTC”), whichrequires all advertising be truthful, not deceptive or unfair, and evidence based.The HyperSound Clear 500P and the HyperSound Tinnitus Module were regulated by the FDA as medical devices pursuant to the Federal Food, Drug,and Cosmetic Act, or FDCA, and implementing regulations. HyperSound Clear 500P received 510(k) clearance permitting over-the-counter (“OTC”)commercial distribution for use as a group auditory trainer or group hearing aid and the HyperSound Tinnitus Module feature received 510(k) clearance forprescription use in the temporary relief of tinnitus symptoms. In connection with the recent restructuring of the HyperSound business, we terminated sales ofHyperSound Clear 500P products, and in March 2017 we deactivated our FDA listing of these devices. We also did not renew our 2017 European Unioncertifications for HyperSound Clear 500P devices. Any future sales of regulated products would require new registrations and certifications.We continue to be subject to FDA’s requirements for marketed medical devices with respect to those HyperSound Clear 500P products that have alreadybeen sold, such as the Quality System Regulation, or QSR (which imposes procedural, documentation and record keeping requirements regarding themanufacture of medical devices); the Medical Device Reporting regulation (which requires that manufacturers report to the FDA if their device may havecaused or contributed to a death or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were torecur); and the Reports of Corrections and Removals regulation (which requires manufacturers to report recalls and field actions to the FDA if initiated toreduce a risk to health posed by the device or to remedy a violation of the FDCA that may pose a risk to health). FDA enforces these requirements byinspection and market surveillance. If the FDA finds a violation, it can institute a wide range of enforcement actions, ranging from a public warning letter tomore severe sanctions such as fines, penalties, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions ortotal shutdown of production, and criminal prosecution.We are subject to various environmental laws and regulations that could impose substantial costs on us and may adversely affect our business, operatingresults and financial condition.Our operations and some of our products are regulated under various federal, state, local and international environmental laws. In addition, regulatorybodies in many of the jurisdictions in which we operate propose, enact and amend environmental laws and regulations on a regular basis. The environmentallaws and regulations applying to our business include those governing the discharge of pollutants into the air and water, the management, disposal andlabeling of, and exposure to, hazardous substances and wastes and the cleanup of contaminated sites. If we were to violate or become liable under theseenvironmental laws, we could be required to incur additional costs to comply with such regulations and may incur fines and civil or criminal sanctions, third-party property damage or personal injury claims, or could be required to incur substantial investigation or remediation costs. Liability under environmentallaws may be joint and several and without regard to comparative fault. The ultimate costs under environmental laws and the timing of these costs are difficultto predict. Although we cannot predict the ultimate impact of any new environmental laws and regulations, such laws may result in additional costs ordecreased revenue, and could require that we redesign or change how we manufacture our products, any of which could have a material adverse effect on ourbusiness. Additionally, to the extent that our competitors choose not to abide by these environmental laws and regulations, we may be at a cost disadvantage,thereby hindering our ability to effectively compete in the marketplace.Failure to comply with the U.S. Foreign Corrupt Practices Act or other applicable anti-corruption legislation could result in fines, criminal penalties andan adverse effect on our business.We operate in 44 countries, including countries known to have a reputation for corruption. We are committed to doing business in accordance withapplicable anti-corruption laws. We are subject, however, to the risk that our officers, directors, employees, agents and collaborators may take actiondetermined to be in violation of such anti-corruption laws, including the U.S. Foreign Corrupt Practices Act of 1977, the U.K. Bribery Act 2010, the EuropeanUnion Anti-Corruption Act and other17 similar laws, or that subjects us to trade sanctions administered by the Office of Foreign Assets Control and the U.S. Department of Commerce. Any suchviolation could result in substantial fines, sanctions, civil and/or criminal penalties or curtailment of operations in certain jurisdictions, and might adverselyaffect our results of operations. In addition, actual or alleged violations could damage our reputation and ability to do business.Risks Related to Ownership of our Common StockIf we cannot meet Nasdaq’s continuing listing requirements and Nasdaq rules, Nasdaq may delist our securities, which could negatively affect us, the priceof our securities and your ability to sell our securities.Although our shares are currently listed on Nasdaq, we may not be able to meet the continued listing requirements of Nasdaq, which require, amongother things, a minimum bid price of $1.00 per share for common shares listed on the exchange and minimum levels of stockholders' equity and the marketvalue of our common stock outstanding. As previously disclosed, on May 9, 2017, we received a written notice from the Listing Qualifications Department ofNasdaq indicating that the Company was not in compliance with Nasdaq Listing Rule 5450(a)(1) (the “Bid Price Rule”) because the bid price for ourcommon stock had closed below $1.00 per share for the previous 30 consecutive business days. In accordance with Nasdaq Listing Rule 5810(c)(3)(A), theCompany was provided 180 calendar days, or until November 6, 2017, to regain compliance with the Bid Price Rule. Also as previously disclosed, onNovember 9, 2017, the Company made a request to the Nasdaq hearing panel to provide the Company an additional 180 calendar days to regain compliancewith the Bid Price Rule, which stayed the potential delisting of the Company’s common stock under Nasdaq Listing Rule 5815(a)(1) pending the hearingpanel’s decision. On January 17, 2018, the hearing panel approved the Company’s request for an additional 180 calendar days, or until May 7, 2018, toregain compliance with the Bid Price Rule.In addition, on January 16, 2018, the Company received a written notice from the Nasdaq Listing Qualifications Department indicating that theCompany is not in compliance with Nasdaq Listing Rule 5450(b)(2)(C) (the “Market Value Rule”) because the market value of publicly held shares of itscommon stock was less than $15 million for 30 consecutive business days. In accordance with Nasdaq Listing Rule 5810(c)(3)(D), the Company has 180calendar days, or until July 16, 2018, to regain compliance with the Market Value Rule. To regain compliance, the market value of publicly held shares of theCompany’s common stock must meet or exceed $15 million for a minimum of 10 consecutive business days.While we are actively considering implementation of customary resolutions, including a reverse stock split, if we are unable to regain compliance withthe Bid Price Rule and/or the Market Value Rule, if our efforts are unsuccessful or we are otherwise unable to satisfy the Nasdaq criteria for maintaining ourlisting, our securities could be subject to delisting. As a consequence of any such delisting, our stockholders would likely find it more difficult to dispose of,or to obtain accurate quotations as to the prices of, our securities. In the event of a delisting, we could face significant material adverse consequencesincluding limited liquidity for our securities, a limited amount of news and analyst coverage for our Company and a decreased ability to issue additionalsecurities or obtain additional financing in the future.Ownership of our common stock is highly concentrated, and we are a “controlled company” within the meaning of the corporate governance standards ofNasdaq and, as a result, qualify for, and rely on, exemptions from certain corporate governance requirements.Certain Turtle Beach stockholders acting as a group beneficially own or control approximately 51% of our common stock. Accordingly, thesestockholders, acting as a group pursuant to a stockholder agreement, have substantial influence over the outcome of our corporate actions requiringstockholder approval, including the election of directors, any merger, consolidation or sale of all or substantially all of our assets or any other significantcorporate transaction. These stockholders also may exert influence in delaying or preventing a change in control of the Company, even if such change incontrol would benefit our other stockholders. In addition, the significant concentration of stock ownership may adversely affect the market value of ourcommon stock due to investors’ perception that such conflicts of interest may exist or arise.Additionally, we have elected to be treated as a “controlled company” under Nasdaq rules. A “controlled company” under Nasdaq rules is a listedcompany more than 50% of the voting power of which is held by an individual, a group or another company (and which elects to be treated as a “controlledcompany”). Certain stockholders of Turtle Beach constitute a group controlling more than 50% of the voting power of our voting stock. As a “controlledcompany,” we are permitted to, and have, opted out of certain Nasdaq rules that would otherwise require (i) a majority of the members of our board to beindependent, (ii) that our compensation committee be comprised entirely of independent directors and (iii) that we establish a nominating and governancecommittee comprised entirely of independent directors, or otherwise ensure that director nominees are determined or recommended to our board by theindependent members of our board. Accordingly, our stockholders may not have the same protections afforded to stockholders of companies that are subjectto all of the corporate governance requirements of Nasdaq.18 If the stockholder group ceases to own at least 50% of our outstanding common stock, we will no longer be eligible to be treated as a controlledcompany. Pursuant to Nasdaq’s listing rules, upon ceasing to be a controlled company, we would be required to regain compliance with Nasdaq’s listingstandards applicable to non-controlled companies, including (i) within 90 days, reconfiguring the Nominating and Governance Committee of our board ofdirectors such that a majority of the members of the committee would be independent and (ii) within 12 months, (x) reconfiguring our board of directors suchthat a majority of the directors would be independent and (y) reconfiguring the Compensation and Nominating and Governance Committees of the board ofdirectors such that all members of such committees would be independent.Item 1B - Unresolved Staff CommentsNone.Item 2 - PropertiesThe table below describes our principal facilities as of December 31, 2017.LocationState or CountryPrincipal Business ActivityApprox.

Although the amount of any liabilitythat could arise with respect to these actions cannot be determined with certainty, in the Company’s opinion, any such liability will not have a materialadverse effect on its consolidated financial position, consolidated results of operations or liquidity.On August 5, 2013, VTBH and the Company (f/k/a Parametric) announced that they had entered into the Merger Agreement pursuant to which VTBHwould acquire an approximately 80% ownership interest and existing shareholders would maintain an approximately 20% ownership interest in thecombined company. Following the announcement, several shareholders filed class action lawsuits in California and Nevada seeking to enjoin the Merger.The plaintiffs in each case alleged that members of the Company’s Board of Directors breached their fiduciary duties to the shareholders by agreeing to aMerger that allegedly undervalued the Company. VTBH and the Company were named as defendants in these lawsuits under the theory that they had aidedand abetted the Company's Board of Directors in allegedly violating their fiduciary duties. The plaintiffs in both cases sought a preliminary injunctionseeking to enjoin closing of the Merger, which, by agreement, was heard by the Nevada court with the California plaintiffs invited to participate. OnDecember 26, 2013, the court in the Nevada cases denied the plaintiffs’ motion for a preliminary injunction. Following the closing of the Merger, the Nevadaplaintiffs filed a second amended complaint, which made essentially the same allegations and sought monetary damages as well as an order rescinding theMerger. The California plaintiffs dismissed their action without prejudice, and sought to intervene in the Nevada action, which was granted. Subsequent tothe intervention, the plaintiffs filed a third amended complaint, which made essentially the same allegations as prior complaints and sought monetarydamages. On June 20, 2014, VTBH and the Company moved to dismiss the action, but that motion was denied on August 28, 2014. That denial was appealedto the Nevada Supreme Court. On September 14, 2017, a unanimous en banc panel of the Nevada Supreme Court granted defendants’ petition for writ ofmandamus and ordered the trial court to dismiss the complaint, but did provide a limited basis upon which plaintiffs could seek to amend their complaint.Plaintiffs filed an amended complaint on December 1, 2017, and motions to dismiss were filed on January 2, 2018. The court will hear those motions onMarch 12, 2018. The Company believes that Plaintiffs’ claims are without merit.On February 18, 2015, Dr. John Bonanno, a minority shareholder of Series B Preferred Stock of VTBH, filed a complaint in Delaware Chancery Courtalleging breach of contract against VTBH. According to the complaint, the Merger purportedly triggered a contractual obligation for VTBH to redeem Dr.Bonanno's preferred stock. Dr. Bonanno requests a declaratory judgment stating that he is entitled to damages including a redemption of his stock for theredemption value of $15.1 million (equal to the original issue price of his stock plus accrued dividends) as well as other costs and expenses. On February 8,2016, the Delaware Chancery Court granted VTBH's motion to dismiss for improper venue, and Dr. Bonnano's complaint was dismissed without prejudice. InJanuary of 2017, Dr. Bonanno filed a complaint in New York state court alleging breach of19 contract against VTBH and seeking a declaratory judgment that he is entitled to damages and specific performance, including redemption of his stock. VTBHanswered the complaint on March 7, 2017. At the order of the Court, the parties filed cross-motions for summary judgment on March 31, 2017, on the solequestion of whether the Merger was a defined event in the purported contract entitling Dr. Bonnano to redemption of his shares. The cross-motions forsummary judgment were fully briefed and heard on July 6, 2017. On September 1, 2017, the Court denied Defendant’s motion for summary judgment andgranted Plaintiff’s motion for partial summary judgment. On October 5, 2017, a status conference was held that set a pre-trial schedule such that all merits andexpert discovery will conclude on May 3, 2018 and a trial readiness conference will be held on May 4, 2018. On October 11, 2017, VTBH filed a motion toreargue plaintiff’s motion for summary judgment in the trial court, specifically seeking clarification that Defendant’s affirmative defenses to liability remainavailable, which was granted. On the same day, VTBH filed a notice of appeal of the Court’s decision on summary judgment in its entirety. The plaintiff’sability to recover any damages is subject to certain limitations, including, but not limited to, legally available funds. VTBH maintains that the Merger didnot trigger any obligation to redeem Mr. Bonanno's preferred stock.On July 20, 2016, Bigben Interactive S.A. (“BigBen”) filed a statement of claim before the Regional Court of Berlin, Germany against VTB, whichstatement of claim was formally served upon VTB on June 28, 2017. The statement of claim alleges that VTB’s termination of a distribution agreement byand between BigBen and VTB breached the terms thereof and was invalid, and that BigBen is entitled to damages amounting to €5.0 million plus accruedinterests thereon plus certain additional damages as a result of such invalid termination. VTB filed its statement of defense with the court on September 21,2017. VTB maintains that its termination of the agreement was valid and that BigBen’s claims against it are without merit. VTB's statement of defense wassubmitted to the plaintiff and the court has granted the option to submit a further written statement in reply to the statement of defense.The Company will continue to vigorously defend itself in the foregoing matters. However, litigation and investigations are inherently uncertain.Accordingly, the Company cannot predict the outcome of these matters. The Company has not recorded any accrual at December 31, 2017 for contingentlosses associated with these matters based on its belief that losses, while possible, are not probable. Further, any possible range of loss cannot be reasonablyestimated at this time. An unfavorable resolution of these matters could have a material adverse effect on the Company’s business, results of operations,financial condition or cash flows. The Company is engaged in other legal actions not described above arising in the ordinary course of its business and, whilethere can be no assurance, believes that the ultimate outcome of these other legal actions will not have a material adverse effect on its business, results ofoperations, financial condition or cash flows.Item 4 - Mine Safety DisclosuresNot applicable.20 PART IIItem 5 - Market for the Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity SecuritiesThe Company's stock is traded on the NASDAQ Global Market under the symbol “HEAR.” The following table sets forth the high and low sale prices pershare of our common stock on the NASDAQ for the period indicated: Market Price High LowFiscal Year 2017 First Quarter$1.74 $0.87Second Quarter0.96 0.65Third Quarter0.99 0.56Fourth Quarter0.86 0.42 High LowFiscal Year 2016 First Quarter$2.07 $0.91Second Quarter1.42 0.83Third Quarter1.55 0.91Fourth Quarter2.00 1.21The closing price of our common stock on February 28, 2018 was $0.45 per share.

Management's Discussion and Analysis of Financial Condition and Results of OperationsThe following discussion should be read in conjunction with our consolidated financial statements and the notes thereto. This discussion summarizes thesignificant factors affecting our results of operations and the financial condition of our business during each of the fiscal years in the three-year periodended December 31, 2017. Turtle Beach Corporation (herein referred to as the “Company,” “we,” “us,” or “our”), headquartered in San Diego, California and incorporated in the state ofNevada in 2010, is a premier audio technology company with expertise and experience in developing, commercializing and marketing innovative productsacross a range of large addressable markets operating under two reportable segments, Turtle Beach® (“Headset”) and HyperSound®.•Turtle Beach is a worldwide leading provider of feature-rich gaming headset solutions for use across multiple platforms, including video game andentertainment consoles, handheld consoles, personal computers, mobile and tablet devices.•HyperSound technology is an innovative patent-protected sound technology that delivers immersive, directional audio with applications in digitalsignage and kiosks, consumer electronics and hearing healthcare.Business TrendsGaming Headset MarketBased on sales tracking data from The NPD Group, Inc (“NPD Group”), the gaming headset market in our largest market, North America, declined just over4% in in 2017 vs. 2016 driven by a weaker overall console gaming market for the first nine months of the year followed by an increase of nearly 3% in thefourth quarter with almost 6% in both November and December reflecting strong launches of several major games. The company gained share in NorthAmerica to 42.1% from 41.9% in 2016.In the United Kingdom, our second largest market, the gaming headset market increased by 1.9% in 2017 driven by a strong Q4 which grew by 3.6%. Behindthe strength of our new launches, Turtle Beach outpaced the market in the holiday season and, for the full year grew by 12.5% over the prior year. Thecompany gained share in the UK to 51.7% from 46.9% in 2016.Major retailers of gaming headsets entered 2017 with a higher than normal level of inventory due to a weaker 2016 holiday in the gaming market thanexpected. This resulted in lower sales in the first half of the year as the usual level of replenishment orders were not needed until the higher channelinventories were reduced. In addition, many major retailers reduced their run-rate inventory levels as part of their efforts to improve their overall businessoperations. Several retailers further reduced their run-rate inventories during holiday causing sporadic stock-outs of certain of our products. These retailersrestocked aggressively early in 2018.SeasonalityOur gaming headset business is seasonal with a significant portion of sales and profits typically occurring around the holiday period. Historically, morethan 45% of headset business revenues are generated during the period from September through December as new headsets are introduced and consumersengage in holiday shopping.HyperSoundHyperSound technology is a pioneering audio solution that provides an effective means of projecting sound in a highly directional manner, without useof large speaker arrays, to a specific location creating a precise audio zone. HyperSound directs a beam of audio to targeted listeners in a specific spot,delivering an immersive, 3D-like audio experience. In June 2016, we unveiled HyperSound Glass, transparent directional speakers, and have startedexploration of potential commercial licensing opportunities.Our business model for HyperSound has evolved into a licensing strategy, focusing on out licenses to companies in the retail space for more precisemarketing. In October 2017, we signed a licensing contract with Waves Systems to incorporate HyperSound technology for customer contact points such asretail point of sales, kiosks, digital signage, wayfinding, museum exhibits, meeting halls and more.24 Results of OperationsManagement OverviewDue to higher-than-normal channel inventory entering the year and sustained overly cautious ordering by several large retailers, some of which weresporadically out-of-stock, net revenues decreased $24.8 million, or 14.3%, to $149.1 million. Despite this challenging environment, Turtle Beach grew itsleading revenue share to 42.2% for 2017, based on recent NPD Group North American data, holding the majority stake for leading headsets.Our Recon series, which is the leading model for both Playstation® and Xbox increased to 45.2% market share. This growth is partially attributable tothe Recon Camo, which has gained popularity and momentum from the Call of Duty return to World War II theme, compounded with the steady sales of ourRecon 50X and Recon 50P models. While our new additions, the Stealth 600 and Stealth 700, finished as the top model by market share for their respectivetiers.Additionally, Turtle Beach Europe, which relocated its warehouse and storage locations to streamline logistics, improving both delivery time and costs,delivered a successful year with revenues in the Europe and the United Kingdom up to $41.4 million, or an increase of 10.4% over the prior year.For 2017, our reported net loss decreased to $3.2 million, or diluted net loss per share of $0.07, and cash from operating activities increased to $3.4million, which we believe reflects the underlying profit potential as the leading console gaming headset brand and provider with the removal of HyperSoundmarketing and development costs, which declined to $1.0 million from $10.4 million in 2016.Forward looking, we see opportunities to refine and improve on our high quality headsets to accelerate growth in the global personal computer gamingheadset market and will continue to evaluate opportunities to expanding our headset portfolio to that market. Additionally, we intend to continue to developour eSports presence and lay the groundwork for future growth opportunities internationally and in new categories such as mobile gaming and virtual reality.Our long-term objective is to leverage these additional growth opportunities to drive double-digit revenue growth given our expectation that the consolegaming headset market will grow in the low to mid-single digits over the coming years.Key Performance Indicators and Non-GAAP MeasuresManagement routinely reviews key performance indicators including revenue, operating income and margins, and earnings per share, among others. Inaddition, we believe certain other measures provide useful information to management and investors about us and our financial condition and results ofoperations for the following reasons: (i) it is one of the measures used by our board of directors and management team to evaluate our operating performance;(ii) it is one of the measures used by our management team to make day-to-day operating decisions; (iii) the adjustments made are often viewed as either non-recurring or not reflective of ongoing financial performance or have no cash impact on operations; and (iv) it is used by securities analysts, investors andother interested parties as a common operating performance measure to compare results across companies in our industry by adjusting for potentialdifferences caused by variations in capital structures (affecting relative interest expense), and the age and book value of facilities and equipment (affectingrelative depreciation and amortization expense). These metrics, however, are not measures of financial performance under accounting principles generallyaccepted in the United States of America (“GAAP”) and, given the limitations of these metrics as analytical tools, should not be considered a substitute forgross profit, gross margins, net income (loss) or other consolidated income statement data as determined in accordance with GAAP. We consider the followingnon-GAAP measure, which may not be comparable to similarly titled measures reported by other companies, to be key performance indicators:•Adjusted EBITDA is defined as net income (loss) before interest, taxes, depreciation and amortization, stock-based compensation (non-cash) and,certain special items that we believe are not representative of core operations.•Cash Margins is defined as gross margin excluding depreciation, amortization and stock-based compensation.25 Adjusted EBITDAAdjusted EBITDA (and a reconciliation to Net loss, the nearest GAAP financial measure) for the years ended December 31, 2017, 2016 and 2015 are asfollows: Year Ended December 31, 20172016 2015 (in thousands)Net loss $(3,248) $(87,182) $(82,907)Interest expense 7,916 7,447 5,099Depreciation and amortization 4,422 9,194 7,916Stock-based compensation 1,430 3,960 5,897Income tax expense (benefit) 593 (387) 2,393Impairment charge — 63,236 49,822Business transaction costs — — —Restructuring charges 533 664 399HyperSound business transition charge (79) 7,079 —Adjusted EBITDA $11,567 $4,011 $(11,381)Comparison of the Year Ended December 31, 2017 to the Year Ended December 31, 2016Net loss for the year ended December 31, 2017 was $3.2 million compared to a net loss of $87.2 million in the prior year period, including $1.9 million and$0.9 million of net loss attributable to the Headset segment, for the year ended December 31, 2017 and the prior year, respectively.For the year ended December 31, 2017, Adjusted EBITDA on a consolidated basis was $11.6 million, including investments of $1.0 million in theHyperSound business, compared to Adjusted EBITDA on a consolidated basis of $4.0 million, including investments of $10.4 million in the HyperSoundbusiness from the year ended December 31, 2016.Headset Adjusted EBITDA totaled approximately $12.6 million in the year ended December 31, 2017 compared to $14.4 million in the prior year thatexcluded $2.9 million of allocated costs, primarily due to improved margins driven by product and logistical costs savings, certain initiatives to reduceoverhead costs, a reduction in marketing spend and a foreign exchange benefit.Comparison of the Year Ended December 31, 2016 to the Year Ended December 31, 2015Net loss for the year ended December 31, 2016 was $87.2 million compared to a net loss of $82.9 million in the prior year period, including $0.2 million and$17.2 million of net loss attributable to the Headset segment, for the year ended December 31, 2016 and the prior year, respectively.For the year ended December 31, 2016, Adjusted EBITDA on a consolidated basis was $4.0 million, including investments of $10.4 million in theHyperSound business, compared to Adjusted EBITDA on a consolidated basis of $(11.4) million, including investments of $13.8 million in the HyperSoundbusiness from the year ended December 31, 2015.Headset Adjusted EBITDA totaled approximately $14.4 million in the year ended December 31, 2016 compared to $2.4 million in the prior year, despite thenegative impacts of $2.4 million related to foreign currency, as new-gen headset consumer demand on both platforms continued to drive higher NorthAmerican and United Kingdom retailer sales volumes and product mix driven margin improvement.26 Financial ResultsThe following table sets forth the Company’s statements of operations for the periods presented: Year Ended December 31, 2017 2016 2015 (in thousands)Net Revenue$149,135 $173,978 $162,747Cost of Revenue98,132 131,368 122,056Gross Profit51,003 42,610 40,691Gross Margin34.2% 24.5% 25.0% Operating expenses46,205 120,311 115,090Operating income (loss)4,798 (77,701) (74,399)Interest expense7,916 7,447 5,099Other non-operating (income) expense, net(463) 2,421 1,016Loss before income tax expense (benefit)(2,655) (87,569) (80,514)Income tax expense (benefit)593 (387) 2,393Net loss$(3,248) $(87,182) $(82,907)Net Revenue and Gross ProfitHeadset SegmentThe following table summarizes net revenue and gross profit for the periods presented: December 31, 2017 2016 2015 (in thousands)Net Revenue$148,828 $173,323 $161,835Gross Profit51,217 55,221 42,832Gross Margin34.4% 31.9% 26.5%Cash Margin (1)34.8% 32.5% 27.5%(1) Excludes non-cash charges of $0.6 million, $1.1 million and $1.7 million, respectively.Comparison of the Year Ended December 31, 2017 to the Year Ended December 31, 2016Net revenues for year ended December 31, 2017 decreased $24.8 million, or 14.3%, as a result of the negative impact of 2016 holiday channel overhang thatdepressed sales in the first half of the year and business model initiatives to reduce on-hand inventory levels that caused under-ordering by several NorthAmerican retailers, some of which were sporadically out-of-stock, during the 2017 holiday.For the year ended December 31, 2017, gross profit as a percentage of net revenue increased to 34.4% from 31.9% in the prior year. In 2017, with no furtherold-gen inventory overhang, margins were positively impacted by product and logistical costs savings, lower obsolescence reserves and a shift to non-royaltymodels, partially offset by negative fixed costs leveraging on lower sales volumes.Comparison of the Year Ended December 31, 2016 to the Year Ended December 31, 2015Net revenues for year ended December 31, 2016 increased $11.2 million, or 6.9%, with 28.8% increase in new-gen headset sales on robust North Americanretailer sales (up 10.9%) and less promotional activity as a result of continued stronger-than-expected demand for our entry-level Recon series headsets,positive consumer response to the introduction and sales of the Stealth 420X+ and Playstation compatible headset market gains across all price points leadby the Ear Force PX24 and the introduction of the Stealth 520.27 For the year ended December 31, 2016, gross profit as a percentage of net revenue increased to 31.9% from 26.5% in the prior year. The year-over-yearimproved margin was primarily due to product mix, as heavily discounted old-gen products are no longer a significant portion of revenues with new-genheadsets up to 92.3% of net revenues, a channel mix shift to higher margin North America retailers as well as an operational move away from brandedheadsets that reduced third party licensing and royalty costs.Operating Expenses Year Ended December 31, 2017 2016 2015 (in thousands)Selling and marketing$24,385 $28,572 $31,829Research and development5,587 8,259 11,556General and administrative15,700 19,580 21,484Business transaction costs— — —Goodwill and other intangible asset impairment— 63,236 49,822Restructuring charges533 664 399Total operating expenses$46,205 $120,311 $115,090 By Segment: Headset$45,093 $46,588 $51,530HyperSound$1,112 $73,723 $63,560Selling and MarketingSelling and marketing expense for the year ended December 31, 2017 totaled $24.4 million, or 16.4% as a percentage of net revenues, compared to $28.6million, or 16.4% as a percentage of net revenues, for the prior year. This decrease was attributable to the reduction of HyperSound business related salesforce and marketing campaigns, and lower Headset marketing spend as compared to the prior year that included additional support for certain new productintroductions.Selling and marketing expense for the year ended December 31, 2016 totaled $28.6 million, or 16.4% as a percentage of net revenues, compared to $31.8million, or 19.6% as a percentage of net revenues, for the prior year. This decrease was attributable to headcount reductions in connection with our marketingdepartment realignment ($0.7 million), lower retail marketing and depreciation, as certain of our major retail customers have shifted away from independentin-store displays.Research and DevelopmentOur Headset business continued to invest in patent protections and new product innovations, such as the industry-first direct to Xbox connectivity in therecent Stealth 700, however, as a result of our product development realignment in connection with the HyperSound business transition ($3.0 million),research and development expenses decreased for the year ended December 31, 2017 versus the comparable prior year period.For the year ended December 31, 2016, despite the continued development initiatives such as the Stealth 350VR headset, Stream Mic and HyperSound Glass,research and development expenses decreased versus the prior year on cost reductions following the launch of the HyperSound Clear 500P product ($3.0million).General and AdministrativeGeneral and administrative expenses for the year ended December 31, 2017 decreased $3.9 million to $15.7 million compared to $19.6 million for the yearended December 31, 2016. The year over year decrease was primarily due to a reduction in HyperSound related expenses ($2.6 million), headcountreductions in the Headset business ($0.8 million) and lower non-cash stock compensation charges.General and administrative expenses for the year ended December 31, 2016 decreased $1.9 million to $19.6 million compared to $21.5 million for the yearended December 31, 2015. The year over year decrease was primarily due to a lower non-cash28 stock compensation charges as compared to incremental expense in connection with our stock option exchange in the prior year ($1.1 million), a reduction inHyperSound related expenses ($0.4 million) and lower legal expenses ($0.3 million).Goodwill and Other Intangibles ImpairmentAs a result of interim and annual impairment tests, for the years ended December 31, 2016 and 2015, respectively, we recorded a $63.2 million and $49.8million goodwill impairment charge, respectively, in connection with the decline in implied fair value of the HyperSound reporting unit. There were no suchcharges in 2017.Restructuring ChargesIn connection with continued efforts to improve our operating efficiency, we completed certain operating expense cost reduction activities, such as theclosure of certain production operations at one of our contract manufacturing operations in China in 2015, consolidated certain operational functions in2016 and most recently, restructured our HyperSound business.Interest ExpenseInterest expense increased $0.5 million for the year ended December 31, 2017 due to additional compound interest related to the Subordinated Notes andSeries B Redeemable Preferred Stock, and non-cash amortization of related debt issuance costs.Interest expense increased $2.3 million for the year ended December 31, 2016 primarily due to $1.6 million of additional interest related to the Term LoanDue 2019 and the Subordinated Notes, and non-cash amortization of related debt issuance costs.Income TaxesIncome tax benefit for the year ended December 31, 2017 was $0.6 million at an effective tax rate of (22.3)% compared to income tax expense of $0.4 millionfor the year ended December 31, 2016 at an effective tax rate of 0.4%. The effective tax rate was primarily impacted by the full valuation allowance ondomestic earnings, foreign entity tax benefits and certain state tax expense.The “Tax Cuts and Jobs Act,” enacted in December 2017, reduces the U.S. federal corporate tax rate from 35% to 21% effective January 1, 2018.Consequently, we have re-measured our deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which isgenerally 21% and recorded a decrease in its net deferred tax assets of $10.5 million with a corresponding decrease to its valuation allowance to account forthis rate reduction. The Act also requires a deemed repatriation of foreign earnings and profits, determined as of either November 2, 2017 or December 31,2017, whichever amount is greater. As such, the Company reported a deemed repatriation of foreign earnings totaling $0.5 million as of December 31, 2017related to its European subsidiary.Income tax benefit for the year ended December 31, 2016 was $0.4 million at an effective tax rate of 0.4% compared to income tax expense of $2.4 millionfor the year ended December 31, 2015 at an effective tax rate of (3.0)%. The effective tax rate was primarily impacted by the full valuation allowance ondomestic earnings, foreign entity tax benefits and certain state tax expense.Other Non-Operating (Income) ExpensesOther non-operating income totaled $0.5 million as a result of the U.S. dollar weakening compared to other non-operating expense for the year endedDecember 31, 2016 to $2.4 million due to negative effect of the Brexit vote on exchange rates as it relates to our United Kingdom operations.Liquidity and Capital ResourcesOur primary sources of working capital are cash flow from operations and availability of capital under our revolving credit facility. We have fundedoperations and acquisitions in recent periods with operating cash flows, and proceeds from debt and equity financings.29 The following table summarizes our sources and uses of cash: 2017 2016 2015 (in thousands)Cash and cash equivalents at beginning of period$6,183 $7,114 $7,908Net cash provided by (used for) operating activities3,418 (1,830) (15,133)Net cash used for investing activities(4,411) (3,229) (6,693)Net cash provided by (used for) financing activities(162) 4,213 21,134Effect of foreign exchange on cash219 (85) (102)Cash and cash equivalents at end of period$5,247 $6,183 $7,114Operating activitiesCash provided by operating activities for the year ended December 31, 2017 was $3.4 million, an increase of $5.2 million as compared to cash used foroperating activities of $1.8 million for the year ended December 31, 2016. The year-over-year increase is primarily the result of lower HyperSoundinvestment, Company-wide reduction in force and deferred marketing spend, partially offset by lower gross receipts and inventory turnover due to reducedsales volumes.Cash used for operating activities for the year ended December 31, 2016 was $1.8 million, a decline of $13.3 million as compared to $15.1 million forthe year ended December 31, 2015. The year-over-year decrease is primarily the result of certain operational actions to lower net cash burn in the HyperSoundbusiness and better align costs with our revenue, and increased Headset cash flows on the strength of our new-gen portfolio, product cost improvements andcertain operating expense cost reduction efforts.Investing activitiesCash used for investing activities was $4.4 million during the year ended December 31, 2017 compared to $3.2 million in 2016, as the Company refreshed itsadvertising displays in certain major retailers.Cash used for investing activities was $3.2 million during the year ended December 31, 2016 compared to $6.7 million in 2015, primarily due to lowercapital expenditures compared to certain tooling purchases in connection with the expansion of our headset portfolio and the initial production line forHyperSound Clear 500P in the prior year. In 2016, capital expenditures primarily related to interactive display purchases and certain website costs.Financing activitiesNet cash provided by financing activities was $0.2 million during the year ended December 31, 2017 compared to $4.2 million and $21.1 million duringthe years ended December 31, 2016 and 2015, respectively. Financing activities in 2017 included net borrowings on our revolving credit facilities of $2.6million, term loan repayments of $2.6 million of term loan repayments and $0.1 million in debt issuance costs related to recent debt amendments.Financing activities in 2016 included $6.0 million of proceeds from the sale of common stock and net borrowings on our revolving credit facilities of $3.4million, partially offset by $4.0 million of term loan repayments and $1.2 million in debt issuance costs related to recent debt amendments.Financing activities in 2015 included the issuance of a $15 million term loan and $16.3 million principal amount ofsubordinated notes, partially offset by repayments of term loans and net payments on our revolving credit facilities of $8.8million.Management assessment of liquidityManagement believes that our current cash and cash equivalents, the amounts available under our revolving credit facility and cash flows derived fromoperations will be sufficient to meet anticipated cash needs for working capital and capital expenditures for at least the next 12 months. Significantassumptions underlie this belief, including, among other things, that there will be no material adverse developments in our business, liquidity or capitalrequirements.30 We believe the combination of our revolving credit facility, long-term debt and cash flow generated by our gaming headset business and reduced costsrelated to the HyperSound business will provide the necessary liquidity to fund our annual working capital needs.Foreign cash balances at December 31, 2017 and December 31, 2016 were $0.1 million and $0.2 million, respectively.Revolving Credit FacilityOn March 31, 2014, Turtle Beach and certain of its subsidiaries entered into a new asset-based revolving credit agreement (“Credit Facility”) with Bank ofAmerica, N.A., as Agent, Sole Lead Arranger and Sole Bookrunner, which replaced the then existing loan and security agreement. The Credit Facility, whichexpires on March 31, 2019, provides for a line of credit of up to $60 million inclusive of a sub-facility limit of $10 million for TB Europe, a wholly ownedsubsidiary of Turtle Beach. The Credit Facility may be used for working capital, the issuance of bank guarantees, letters of credit and other corporatepurposes.The Company and its subsidiaries are required to comply with various customary covenants including, (i) maintaining minimum EBITDA in each trailingtwelve month period, (ii) maintaining a Consolidated Leverage Ratio to be measured on the last day of each month, (iii) maintaining certain cash flow levels,in the aggregate and with respect to its HyperSound segment, during each rolling four week period beginning with the period ended October 31, 2016through December 31, 2018, (iv) limitation on capital expenditures in excess of $5 million in each of the years ending December 31, 2018 and 2019 and (v)in the event the Company’s availability is less than certain specified amounts, obtaining additional funding from the issuance of a subordinated promissorynote provided by SG VTB (the “Promissory Note”).The maximum credit availability for loans and letters of credit under the Credit Facility is governed by a borrowing base determined by the application ofspecified percentages to certain eligible assets, primarily eligible trade accounts receivable and inventories, and is subject to discretionary reserves andrevaluation adjustments.Amounts outstanding under the Credit Facility bear interest at a rate equal to either a rate published by Bank of America or the LIBOR rate, plus in each case,an applicable margin, which is between 1.00% to 1.50% for U.S. base rate loans and between 2.00% to 2.50% for U.S. LIBOR loans and U.K. loans. As ofDecember 31, 2017, interest rates for outstanding borrowings were 5.75% for base rate loans and 3.74% for LIBOR rate loans. In addition, Turtle Beach isrequired to pay a commitment fee on the unused revolving loan commitment at a rate ranging from 0.25% to 0.50%, and letter of credit fees and agent fees.If certain availability thresholds are not met, meaning that the Company does not have receivables and inventory which are eligible to borrow on under theCredit Facility in excess of amounts borrowed, the Credit Facility requires the Company and its restricted subsidiaries to maintain a fixed charge coverageratio. The fixed charge ratio is defined as the ratio, determined on a consolidated basis for the most recent four fiscal quarters, of (a) EBITDA minus capitalexpenditures, excluding those financed through other instruments, and cash taxes paid, and (b) Fixed Charges defined as the sum of cash interest expenseplus scheduled principal payments. The current fixed charge coverage ratio of at least 1.15 to 1.00 on the last day of each month while a Covenant TriggerPeriod (as defined in the Credit Facility) is in effect will become effective again after the Company has complied with such ratio for six consecutive months.The Credit Facility also contains affirmative and negative covenants that, subject to certain exceptions, limit our ability to take certain actions, including ourability to incur debt, pay dividends and repurchase stock, make certain investments and other payments, enter into certain mergers and consolidations,engage in sale leaseback transactions and transactions with affiliates and encumber and dispose of assets. Obligations under the Credit Facility are secured bya security interest and lien upon substantially all of the Company's assets.As of December 31, 2017, the Company was in compliance with all the amended financial covenants, and excess borrowing availability was approximately$9.7 million, net of the outstanding Term Loan Due 2018 (as defined below) that is considered to be an additional outstanding amount under the CreditFacility.Term LoansTerm Loan Due 2018On December 29, 2014, the Company amended the Credit Facility with Bank of America to enter in to an additional loan (the“Term Loan Due 2018”) for the repayment of $7.7 million of then existing subordinated debt and accrued interest. The TermLoan Due 2018 resulted in modified financial covenants while it is outstanding, will bear interest at a rate of LIBOR for theapplicable interest period plus 5% and will be repaid in equal monthly installments beginning on April 1, 2015 and ending on31 October 1, 2018, reflecting a six month waiver. Amounts so repaid are recognized by lowering the balance of the term loantranche and increasing the lower interest rate base revolver amount, with no net impact on borrowing availability.As of December 31, 2017, the outstanding principal balance was $1.9 million.Term Loan Due 2019On July 22, 2015, the Company and its subsidiaries, entered into a term loan, guaranty and security agreement (the “Term Loan Due 2019”) with CrystalFinancial LLC, as agent, sole lead arranger and sole bookrunner, Crystal Financial SPV LLC and the other persons party thereto (“Crystal”), which providesfor an aggregate term loan commitment of $15 million that bears interest at a rate per annum equal to the 90-day LIBOR rate plus 10.25%. Under the terms ofthe Term Loan Due 2019, we are required to make payments of interest in arrears on the first day of each month beginning August 1, 2015 and will repay theprincipal in monthly payments beginning January 1, 2016, inclusive of a nine month waiver, with a final payment on June 28, 2019, the maturity date.The Term Loan Due 2019 is secured by a security interest in substantially all of the Company and each of its subsidiaries' working capital assets and issubject to the first-priority lien of Bank of America , N.A., as agent, under the Credit Facility, other than with respect to equipment, fixtures, real propertyinterests, intellectual property, intercompany property, intercompany indebtedness, equity interest in their subsidiaries, and certain other assets specified inan inter-creditor agreement between Bank of America and Crystal.The Company and its subsidiaries are required to comply with various customary covenants including, (i) maintaining minimum EBITDA (as defined in theTerm Loan Due 2019) in each trailing twelve month period, (ii) maintaining a Consolidated Leverage Ratio (as defined in the Term Loan Due 2019) to bemeasured on the last day of each month, (iii) maintaining certain cash flow levels, in the aggregate and with respect to its HyperSound segment, during eachrolling four week period beginning with the period ended October 31, 2016 through December 31, 2018, (iv) limitation on capital expenditures in excess of$5 million in each of the years ending December 31, 2018 and 2019, (v) in the event the Company’s availability is less than certain specified amounts,obtaining additional funding from the issuance of a subordinated promissory note provided by SG VTB (the “Promissory Note”), and (vi) restrictions on theCompany’s and its subsidiaries ability to prepay its subordinated notes, pay dividends, incur debt, create or suffer liens and engage in certain fundamentaltransactions. The agreement permits certain equity holders of the Company to contribute funds to the Company to cure certain financial covenant defaults.The Term Loan Due 2019 contains customary representations, mandatory prepayment events and events of default, including defaults triggered by the failureto make payments when due, breaches of covenants and representations, material impairment in the perfection of Crystal’s security interest in the collateraland events related to bankruptcy and insolvency of the Company and its subsidiaries. Upon an event of default, Crystal may declare all outstandingobligations immediately due and payable (along with a prepayment fee), a default rate of an additional 2.0% may be applied to amounts outstanding andmay take other actions including collecting or taking such other action with respect to the collateral pledged in connection with the term loan.As of December 31, 2017, the Company was in compliance with the amended financial covenants, and the outstanding principal balance was $9.8 million.Subordination AgreementOn November 16, 2015, as a condition precedent to our lenders permitting certain subordinated notes, we entered into a subordination agreement with andbetween certain parties that our obligations under any such notes would be subordinated in right of payment in full of all the Company's obligations underthe Credit Facility and Term Loan Due 2019.32 Subordinated Notes - Related PartyConcurrently with the completion of the Term Loan Due 2019, the Company amended and restated each of its outstanding subordinated notes (the“Amended Notes”). The $18.5 million obligation of the Company under the Amended Notes is subordinate and junior to the prior payment of amounts dueunder the Credit Facility and Term Loan Due 2019. In addition, the stated maturity date of the Amended Notes was extended to September 29, 2019, subjectto acceleration in certain circumstances, such as a change of control in the Company. The Amended Notes bear interest at a rate per annum equal to LIBORplus 10.5% and shall be paid-in-kind by adding the amount to the principal amount due. Further, as consideration for the concessions in the Amended Notes,the Company issued warrants to purchase 1.7 million shares of the Company’s common stock at an exercise price of $2.54 per share.On November 16, 2015, the Company issued a $2.5 million subordinated note (the “November Note”) to SG VTB, the proceeds of which, as set forth in theamendment to the Term Loan Due 2019, were applied against the outstanding balance of the Term Loan Due 2019. The November Note will bear interest at arate of 15% per annum until its maturity date, which is September 29, 2019, and is subordinated to all senior debt of the Company. In connection with theNovember Note, the Company issued a warrant to purchase 1.4 million shares of the Company’s common stock at an exercise price of $2.00 per share.On October 31, 2016, in connection with certain amendments to the Credit Facility and Term Loan Due 2019, the Company and SG VTB entered into thePromissory Note, which states that in the event the Company’s availability under the Credit Facility is less than certain specified amounts, the Company may,upon request, at any time until September 29, 2019 require that SG VTB provide a $2 million subordinated loan. Upon issuance, the loan would bear interestat a rate of either (i) LIBOR plus 10.5% per annum or (ii) 12.0%, dependent upon the Company’s compliance with certain financial covenants and would besubordinated to all senior debt of the Company.In addition, under the terms of the Promissory Note, if and when the funding occurs, as additional consideration the Company would issue to SG VTB awarrant, exercisable for a period of ten years beginning on the date of issuance, to purchase an amount of shares of the Company’s common stock equal to2.4% of the Company’s then fully diluted shares outstanding at an exercise price equal to the closing price on that date.

Thesubordinated notes will bear in-kind interest at a rate of (i) LIBOR plus 9.1% per annum for the first twenty-four months (or six months (or such date datedprovided that the amount of such note is reduced by a specified amount by the six month anniversary of the restatement effective date) with respect to theNovember Note) and (ii) LIBOR plus 10.5% per annum (or 15.0% with respect to the November Note if the prepayment described above does not occur)thereafter until September 2024.Series B Redeemable Preferred StockIn September 2010, VTBH issued 1,000,000 shares of its Series B Redeemable Preferred Stock with a fair value of $12.4 million. We are required to redeemthe Series B Redeemable Preferred Stock on the earlier to occur of September 28, 2030 or the occurrence of a liquidation event (as defined in VTBH'sCertificate of Incorporation) at its original issue price of33 $12.425371 per share plus any accrued but unpaid dividends. The redemption value was $18.9 million and $17.5 million as of December 31, 2017 andDecember 31, 2016, respectively.As further described in Item 3, “Legal Proceedings,” and Note 13, “Commitments and Contingencies,” we are involved in legal proceedings related to themerger of VTBH and Paris Acquisition Corp. involving certain of our stockholders, including the holder of VTBH’s Series B Redeemable Preferred Stock,(the “Series B Holder”), filing a complaint in New York state court alleging breach of contract against VTBH and seeking a declaratory judgment that he isentitled to damages and specific performance, including the redemption of his stock.Critical Accounting EstimatesOur discussion and analysis of our results of operations and capital resources are based on our condensed consolidated financial statements, which have beenprepared in conformity with GAAP. The preparation of these condensed consolidated financial statements requires management to make estimates andassumptions that affect the reported amounts of assets, liabilities, revenue and expenses and the disclosure of contingent assets and liabilities. Managementbases its estimates, assumptions and judgments on historical experience and on various other factors that it believes to be reasonable under the circumstances.Different assumptions and judgments would change the estimates used in the preparation of the condensed consolidated financial statements, which, in turn,could change the results from those reported. Management evaluates its estimates, assumptions and judgments on an ongoing basis.Based on the above, we have determined that our most critical accounting policies are those related to revenue recognition and sales return reserve, inventoryvaluation, asset impairment, and income taxes.Revenue Recognition and Sales Return ReserveRevenue is recognized when products are shipped and title has been transferred to a customer, the sales price is fixed and determinable, and collection isreasonably assured. Product is considered delivered to the customer once it has been shipped and title and risk of loss have been transferred. Net revenue foron-line purchases is recognized when products are shipped from our distribution facilities.Provisions for cash discounts, quantity rebates, and sales returns in the period the sale is recorded, based upon our prior experience and current trends, as areduction of revenue. These revenue reductions are established based upon management’s best estimates at the time of sale following the historical trend,adjusted to reflect known changes in the factors that impact such reserves and allowances, and the terms of agreements with customers.Inventory ValuationInventories are valued at the lower of weighted average cost or market, at the individual item level. Market is determined based on the estimated netrealizable value, which is generally the selling price. Inventory levels are monitored to identify slow-moving items and markdowns are used to clear suchproduct. Physical inventory counts are performed annually in January and estimates are made for any shortage between the date of the physical inventorycount and the balance sheet date.Asset ImpairmentWe have significant long-lived tangible and intangible assets, including goodwill with indefinite lives, which are susceptible to valuation adjustments as aresult of changes in various factors or conditions. We assess the potential impairment of intangible and fixed assets whenever events or changes incircumstances indicate that full recoverability of net asset balances through future cash flows is in question. Goodwill and indefinite-lived intangible assetsare assessed at least annually, but also whenever events or changes in circumstances indicate the carrying values may not be recoverable. Factors we considerimportant, which could trigger an impairment of such assets include significant underperformance relative to historical or projected future operating results;significant changes in the manner of or use of the acquired assets or the strategy for our overall business; significant negative industry or economic trends;significant decline in our stock price for a sustained period; and a decline in our market capitalization below net book value.Management estimates future pre-tax cash flows based on historical experience, knowledge and market data. Estimates of future cash flows require that wemake assumptions and apply judgment, including forecasting future sales and expenses and estimating useful lives of the assets. These estimates can beaffected by factors such as future product development and economic conditions that can be difficult to predict, as well as other factors such as those outlinedin “Risk Factors.” If the expected future cash flows related to the long-lived assets are less than the assets’ carrying value, an impairment loss would berecognized for the difference between estimated fair value and carrying value.34 There are inherent assumptions and estimates used in developing future cash flows requiring management judgment including projecting revenues, interestrates and the cost of capital. Many of the factors used in assessing fair value are outside our control and it is reasonably likely that assumptions and estimateswill change in future periods. These changes can result in future impairments. Income TaxesWe account for income taxes using the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are recognizedbased on the differences between the financial statement carrying value of existing assets and liabilities and their respective tax bases. Deferred tax assets andliabilities are measured using enacted tax rates and laws expected to be in effect when the differences are expected to reverse. The effect of a change in taxrates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. Inherent in the measurement of thesedeferred balances are certain judgments and interpretations of existing tax law and other published guidance as applied to our operations. Our effective taxrate considers our judgment of expected tax liabilities in the various jurisdictions within which we are subject to tax.The determination of the need for a valuation allowance on deferred tax assets requires management to make assumptions and to apply judgment, includingforecasting future earnings, taxable income, and the mix of earnings in the jurisdictions in which we operate. During 2015, as a result of cumulative losses inrecent years primarily due to incremental costs associated with the console transition, acquisition costs and initial investments in the HyperSound business,the Company concluded that a full valuation allowance is required on its net deferred tax assets.The tax effects of uncertain tax positions taken or expected to be taken in income tax returns are recognized only if they are “more likely-than-not” to besustained on examination by the taxing authorities, based on the technical merits as of the reporting date. The tax benefits recognized in the financialstatements from such positions are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimatesettlement. We recognize estimated accrued interest and penalties related to uncertain tax positions in income tax expense.We are currently under examination by certain state and local taxing jurisdictions. Further, at any given time, multiple tax years may be subject toexamination by various taxing authorities. The recorded amounts of income tax are subject to adjustment upon examination, changes in interpretation andchanges in judgment utilized in determining estimates.See Note 1, “Summary of Significant Accounting Policy,” in the notes to the consolidated financial statements for a complete discussion of recent accountingpronouncements. We are currently evaluating the impact of certain recently issued guidance on our financial condition and results of operations in futureperiods.Off-Balance Sheet ArrangementsOff balance sheet arrangements are transactions, agreements, or other contractual arrangements with an unconsolidated entity for which we have anobligation to the entity that is not recorded in the consolidated financial statements. As of December 31, 2017, there are no significant off-balance sheetarrangements.Contractual ObligationsOur principal commitments primarily consist of obligations for minimum payment commitments to leases for office space, redeemable preferred stock, termloans and the revolving credit facility. As of December 31, 2017, the future non-cancelable minimum payments under these commitments were as follows:(in thousands) Payments Due by Period Total Less Than OneYear 1 - 3 Years 3 - 5 Years More Than FiveYearsContractual Obligations: (1) Operating lease obligations (2) $2,663 $984 $1,294 $385 —Series B Redeemable Preferred Stock (3) 52,256 — — — 52,256Long term debt (4) 72,098 42,639 29,459 — —Interest payments on long-term debt (5) 12,010 1,038 10,972 — —Total $139,027 $44,661 $41,725 $385 $52,25635 (1) Contractual obligations exclude tax liabilities of $1.5 million related to uncertain tax positions because we are unable to make a reasonably reliableestimate of the timing of settlement, if any, of these future payments.(2) Operating lease agreements represent obligations to make payments under non-cancelable lease agreements for its facilities.(3) In September 2010, VTBH issued shares of its Series B Redeemable Preferred Stock. If the Series B Redeemable Preferred Stock is still outstanding as ofOctober 2030 or if the Company experiences a liquidation event as defined in VTBH's Certification of Incorporation, the Company will be required toredeem the shares for an aggregate of $52.3 million, which is comprised of the aggregate purchase price of $12.4 million plus cumulative preferreddividends of 8.0% per annum, or $39.5 million in the aggregate. See Note 13, “Commitments and Contingencies”, for further information.(4) On March 31, 2014, the Company entered into the Credit Facility that expires March 31, 2019. However, due to certain terms of the facility, theindebtedness is required to be classified as a current liability. Long term debt includes scheduled principal payments only. See Note 7, “CreditFacilities and Long-Term Debt” for further information.(5) These amounts reflect estimated interest payments under our outstanding long-term debt agreements based on the applicable rates in effect as ofDecember 31, 2017, except for interest payments under our Credit Facility because the amount that will be borrowed in future years is uncertain.Item 7A - Qualitative and Quantitative Disclosures about Market Risk Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. The Company'smarket risk exposure is primarily a result of fluctuations in interest rates, foreign currency exchange rates and inflation.To date, the Company has used derivative financial instruments, specifically foreign currency forward and option contracts, to manage exposure to foreigncurrency risks, by hedging a portion of its forecasted expenses denominated in British Pounds expected to occur within a year. The effect of exchange ratechanges on foreign currency forward and option contracts is expected to offset the effect of exchange rate changes on the underlying hedged item. TheCompany does not use derivative financial instruments for speculative or trading purposes. As of December 31, 2017, we do not have any derivative financialinstruments.Interest Rate RiskThe Company's total variable rate debt is comprised of $38.5 million outstanding under the Credit Facility, $11.7 million presented as term loans and $18.5million of Subordinated Notes. A hypothetical 10% increase in borrowing rates at December 31, 2017 would have resulted in a $0.4 million annual increasein interest expense on the existing principal balance.Foreign Currency Exchange RiskThe Company has exchange rate exposure, primarily, with respect to the British Pound. As of December 31, 2017, 2016 and 2015, our monetary assets andliabilities which are subject to this exposure are immaterial, therefore the potential immediate loss to us that would result from a hypothetical 10% change inforeign currency exchange rates would not be expected to have a material impact on our earnings or cash flows. This sensitivity analysis assumes anunfavorable 10% fluctuation in the exchange rates affecting the foreign currencies in which monetary assets and liabilities are denominated and does nottake into account the offsetting effect of such a change on our foreign currency denominated revenues.Inflation RiskThe Company is exposed to market risk due to the possibility of inflation, such as increases in the cost of its products. Although the Company does notbelieve that inflation has had a material impact on its financial position or results of operations to date, a high rate of inflation in the future may have anadverse effect on the Company’s ability to maintain current levels of gross margin and selling, general and administrative expenses as a percentage of netrevenue if the selling prices of products do not increase with these increased costs.36 Item 8.

Summary of Significant Accounting PoliciesOrganizationTurtle Beach Corporation (“Turtle Beach” or the “Company”), headquartered in San Diego, California and incorporated in the state of Nevada in 2010, is apremier audio technology company with expertise and experience in developing, commercializing and marketing innovative products across a range of largeaddressable markets under the Turtle Beach® and HyperSound® brands. Turtle Beach is a worldwide leading provider of feature-rich headset solutions foruse across multiple platforms, including video game and entertainment consoles, handheld consoles, personal computers, tablets and mobile devices.HyperSound technology is an innovative patent-protected sound technology that delivers immersive, directional audio with applications in digital signageand consumer electronics.VTB Holdings, Inc. (“VTBH”), the parent holding company of the historical business of the headset business, was incorporated in the state of Delaware in2010 with operations principally located in Valhalla, New York. Voyetra Turtle Beach, Inc. (“VTB”) was incorporated in the state of Delaware in 1975.In October 2012, VTB acquired Lygo International Limited (“Lygo”), a private limited company organized under the laws of England and Wales, which wassubsequently renamed Turtle Beach Europe Limited (“TB Europe”).Basis of PresentationThe accompanying consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission(“SEC”) and, in the opinion of management, reflect all adjustments (which include normal recurring adjustments) considered necessary for a fair presentationof the financial position, results of operations, and cash flows for the periods presented. All intercompany accounts and transactions have been eliminated inconsolidation.Uses of EstimatesThe preparation of financial statements in conformity with generally accepted accounting principles requires management to use estimates and assumptionsthat affect the reported amount of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, as well as thereported amounts of revenue and expenses during the reporting period. The significant estimates and assumptions used by management affect: sales returnreserve, allowances for cash discounts, warranty reserve, valuation of inventory, valuation of long-lived assets, goodwill and other intangible assets,depreciation and amortization of long-lived assets, valuation of deferred tax assets, determination of fair value of stock-based awards, stock warrants andshare based compensation. The Company evaluates estimates and assumptions on an ongoing basis using historical experience and other factors and adjuststhose estimates and assumptions when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual resultscould differ from these estimates, and those differences could be material to the consolidated financial statements.Revenue Recognition and Sales Return ReserveNet revenue consists primarily of revenue from the sale of gaming headsets and accessories to wholesalers, retailers and to a lesser extent, on-line customers.Revenue from products is recognized when the product has been delivered to a customer, the sales price is fixed and determinable, and collection isreasonably assured. Product is considered delivered to the customer upon passage of title and risk of loss to the customer. Change in title to the product andrecognition of revenue occurs upon delivery to the customer when sales terms are free on board (“FOB”) destination and at the time of shipment when thesales terms are FOB shipping point and there is no right of return. Net revenue for on-line purchases is recognized when products are shipped from theCompany’s distribution facilities. The Company excludes sales taxes collected from customers from “Net Revenue” in its Consolidated Statements ofOperations.Provisions for cash discounts, quantity rebates, and sales returns are recognized in the period the sale is recorded, based upon our prior experience and currenttrends, as a reduction of revenue. These revenue reductions are established by the Company based upon management’s best estimates at the time of salefollowing the historical trend, adjusted to reflect known changes in the factors that impact such reserves and allowances, and the terms of agreements withcustomers.44 Turtle Beach CorporationNotes to Consolidated Financial Statements - (Continued)Cost of Revenue and Operating ExpensesThe following table illustrates the primary costs classified in each major expense category:Cost of Revenue Operating ExpensesCost to manufacture products; Payroll, bonus and benefit costs;Freight costs associated with moving product from suppliers todistribution center and to customers; Costs incurred in the research and development of new products andenhancements to existing products;Costs associated with the movement of merchandise through customs; Depreciation related to demonstration units;Costs associated with material handling and warehousing; Legal, finance, information systems and other corporate overheadcosts;Global supply chain personnel costs; Sales commissions, advertising and marketing costs.Product royalty costs. Product Warranty ObligationsThe Company provides for product warranties in accordance with the contract terms given to various customers by accruing estimated warranty costs at thetime of revenue recognition. Warranties are generally fulfilled by replacing defective products with new products.Marketing CostsCosts associated with the production of advertising, such as print and other costs, as well as costs associated with communicating advertising that has beenproduced, such as magazine ads, are expensed when the advertising first appears in public. Advertising costs were approximately $4.2 million, $6.2 millionand $5.3 million for the years ended December 31, 2017, 2016 and 2015.The Company also incurs co-operative advertising costs that represent reimbursements to customers for shared marketing expenses for sale of its products.These reimbursements are recorded as reductions of net revenue based on a percentage of sales for all period presented. Co-operative advertisingreimbursements were approximately $3.1 million, $4.0 million and $3.6 million for the years ended December 31, 2017, 2016 and 2015.Deferred Financing CostsDeferred financing costs represent costs incurred in conjunction with our debt financing activities and are capitalized and amortized over the life of therelated financing arrangements. If the debt is retired early, the related unamortized deferred financing costs are written off in the period the debt is retired andare recorded in the statement of operations under the caption “Other non-operating (income) expense, net.”Stock-Based CompensationCompensation costs related to stock options and restricted stock grants are calculated based on the fair value of the stock-basedawards on the date of grant, net of estimated forfeitures. The grant date fair value of awards is determined using the Black-Scholes option-pricing model andthe related stock-based compensation is recognized on a straight-line basis, over the period in which an employee is required to provide service in exchangefor the award, which is generally four years.The Company estimates its forfeiture rate based on an analysis of actual forfeitures and will continue to evaluate the adequacy of the forfeiture rate based onactual forfeiture experience, analysis of employee turnover behavior, and other factors. The impact from any forfeiture rate adjustment would be recognizedin the period of adjustment and if the actual number of future forfeitures differs from estimates, the Company might be required to record adjustments tostock-based compensation expense.For stock-based awards issued to non-employees, including consultants, compensation expense is based on the fair value of theawards calculated using the Black-Scholes option-pricing model over the service performance period. The fair value of options45 Turtle Beach CorporationNotes to Consolidated Financial Statements - (Continued)granted to non-employees for each reporting period is re-measured over the vesting period and recognized as an expense over the period the services arereceived.Exit and Disposal CostsManagement-approved restructuring activities are periodically initiated to achieve cost savings through reduced operational redundancies and to positionthe Company strategically in the market in response to prevailing economic conditions and associated customer demand. Costs associated with restructuringactions can include severance, infrastructure charges to vacate facilities or consolidate operations, contract termination costs and other related charges. Forinvoluntary separation plans, a liability is recognized when it is probable and reasonably estimable. For one-time termination benefits, such as additionalseverance pay or benefit payouts, and other exit costs, such as lease termination costs, the liability is measured and recognized initially at fair value in theperiod in which the liability is incurred, with subsequent changes to the liability recognized as adjustments in the period of change.Net Earnings (Loss) per Common ShareBasic earnings (loss) per share is calculated by dividing net income (loss) associated with common stockholders by the weighted average number of commonshares outstanding during the period. Diluted earnings (loss) per share assumes the issuance of additional shares of common stock by the Company uponexercise of all outstanding stock options, stock warrants and contingently issuable securities if the effect is dilutive, in accordance with the treasury stockmethod.Cash EquivalentsCash and short-term highly liquid investments with original maturity dates of three months or less at time of purchase and no redemption restrictions areconsidered cash and cash equivalents.InventoriesInventories consist primarily of finished goods and related component parts, and are stated at the lower of weighted average cost or market value (estimatednet realizable value) using the first in, first out (“FIFO”) method. The Company maintains an inventory allowance for returned goods, slow-moving andunused inventories based on the historical trend and estimates. Inventory write-downs, once established, are not reversed as they establish a new cost basis forthe inventory. Inventory write-downs are included as a component of cost of revenues in the accompanying consolidated statements of operations.Property and Equipment, netProperty and equipment are presented at cost less accumulated depreciation and amortization. Repairs and maintenance expenditures are expensed asincurred. Depreciation and amortization are computed on a straight-line basis over the following estimated useful lives: Estimated LifeMachinery and equipment 3 yearsSoftware and software development 2-3 yearsFurniture and fixtures 5 yearsTooling 2 yearsLeasehold improvements Term of lease or economic life of asset, if shorterDemonstration units and convention booths 2 yearsValuation of Long-Lived and Intangible Assets and GoodwillAt acquisition, we estimate and record the fair value of purchased intangible assets, which primarily consists of in-process research and development,customer relationships, trademarks and trade names, and patents. The fair values of these intangible assets are estimated based on our assessment. Goodwillis the excess of the purchase price over the fair value of identifiable net assets acquired in business combinations. Goodwill and certain other intangibleassets having indefinite lives are not amortized46 Turtle Beach CorporationNotes to Consolidated Financial Statements - (Continued)to earnings, but instead are subject to periodic testing for impairment. Intangible assets determined to have definite lives are amortized over their remaininguseful lives.Long-lived and intangible assets and goodwill are assessed for the potential impairment of intangible and fixed assets whenever events or changes incircumstances indicate that full recoverability of net asset balances through future cash flows is in question. Goodwill and indefinite-lived intangible assetsare assessed at least annually, but also whenever events or changes in circumstances indicate the carrying values may not be recoverable. Factors that couldtrigger an impairment review, include (a) significant underperformance relative to historical or projected future operating results; (b) significant changes inthe manner of or use of the acquired assets or the strategy for our overall business; (c) significant negative industry or economic trends; (d) significant declinein our stock price for a sustained period; and a decline in our market capitalization below net book value.Assessment for possible impairment is based on the Company’s ability to recover the carrying value of the long-lived asset from the expected future pre-taxcash flows. The expected future pre-tax cash flows are estimated based on historical experience, knowledge and market data. Estimates of future cash flowsrequire the Company to make assumptions and to apply judgment, including forecasting future sales and expenses and estimating the useful lives of assets. Ifthe expected future cash flows related to the long-lived assets are less than the assets’ carrying value, an impairment charge is recognized for the differencebetween estimated fair value and carrying value.When performing our evaluation of goodwill for impairment, if we conclude qualitatively that it is not more likely than not that the fair value of the reportingunit is less than its carrying amount, then the two-step impairment test is not required. If we are unable to reach this conclusion, then we would perform thetwo-step impairment test. Initially, the fair value of the reporting unit is compared to its carrying amount. To the extent the carrying amount of a reportingunit exceeds the fair value of the reporting unit; we are required to perform a second step, as this is an indication that the reporting unit goodwill may beimpaired. In this step, we compare the implied fair value of the reporting unit goodwill with the carrying amount of the reporting unit goodwill andrecognize a charge for impairment to the extent the carrying value exceeds the implied fair value. The implied fair value of goodwill is determined byallocating the fair value of the reporting unit to all of the assets (recognized and unrecognized) and liabilities of the reporting unit in a manner similar to apurchase price allocation. The residual fair value after this allocation is the implied fair value of the reporting unit goodwill. In addition, identifiableintangible assets having indefinite lives are reviewed for impairment on an annual basis using a methodology consistent with that used to evaluate goodwill.There are inherent assumptions and estimates used in developing future cash flows requiring management judgment including projecting revenues, interestrates and the cost of capital. Many of the factors used in assessing fair value are outside our control and it is reasonably likely that assumptions and estimateswill change in future periods. These changes can result in future impairments. In the event our planning assumptions were modified resulting in impairmentto our assets, the associated expense would be included in the Consolidated Statements of Operations, which could materially impact our business, financialcondition and results of operations.In connection with its merger in 2014, the Company performed a valuation of the acquired goodwill and intangible assets and recorded $81.0 million ofgoodwill and $36.4 million of intangible assets based on the fair values of the assets acquired and liabilities assumed. During 2016 and 2015, as a result ofthe Company's impairment assessments, the Company recorded a $63.2 million goodwill and other intangibles impairment charge and a $49.8 milliongoodwill impairment charge, respectively, which resulted in no remaining carrying value as of December 31, 2016. The goodwill and other intangiblesimpairment was attributed to sustained slower than anticipated sales volumes in the HyperSound business and certain plans to reduce operating costs to alignwith current revenues that negatively impacted revenue growth and margin assumptions based on estimates of future operations.Income TaxesThe Company accounts for income taxes in accordance with the asset and liability method. Under the asset and liability method, deferred tax assets andliabilities are recognized based on the differences between the financial statement carrying value of existing assets and liabilities and their respective taxbases, based on enacted tax laws and statutory tax rates applicable to the periods in which the Company expects the temporary differences to reverse. TheCompany had elected to record a “deferred charge” for basis differences relating to intra-entity profits as recognition as a deferred tax asset is prohibited.During 2015, as a result of cumulative losses in recent years primarily due to incremental costs associated with the console transition, acquisition costs andinitial investments in the HyperSound business, the Company concluded that a full valuation allowance is required on its net deferred tax assets. A valuationallowance is established for deferred tax assets when management anticipates that it is more likely than not that all, or a portion of these assets would not berealized. In determining47 Turtle Beach CorporationNotes to Consolidated Financial Statements - (Continued)whether a valuation allowance is warranted, all positive and negative evidence and all sources of taxable income such as prior earnings history, expectedfuture earnings, carryback and carryforward periods and tax strategies are considered to estimate if sufficient future taxable income will be generated torealize the deferred tax asset. The assessment of the adequacy of a valuation allowance is based on estimates of taxable income by jurisdiction and the periodover which deferred tax assets will be recoverable. In the event that actual results differ from these estimates, or these estimates are adjusted in future periodsfor current trends or expected changes in assumptions, the Company may need to modify the level of valuation allowance which could materially impact ourbusiness, financial condition and results of operations.The tax effects of uncertain tax positions taken or expected to be taken in income tax returns are recognized only if they are “more likely-than-not” to besustained on examination by the taxing authorities, based on the technical merits as of the reporting date. The tax benefits recognized in the financialstatements from such positions are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimatesettlement. The Company recognizes estimated accrued interest and penalties related to uncertain tax positions in income tax expense.The Company and its domestic subsidiaries file a consolidated federal income tax return, while the Company’s foreign subsidiary files in its respective localjurisdictions.Fair Value of Financial InstrumentsThe Company determines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between marketparticipants at the measurement date. The Company uses a hierarchical structure to prioritize the inputs used to measure fair value into three broad levels. Thefair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1), then to quoted market prices forsimilar assets or liabilities in active or inactive markets (Level 2) and gives the lowest priority to unobservable inputs (Level 3).Financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, revolving line of credit and long-term debt. Cashequivalents are stated at amortized cost, which approximated fair value as of the consolidated balance sheet dates due to the short period of time to maturity;and accounts receivable and accounts payable are stated at their carrying value, which approximates fair value due to the short time to the expected receipt orpayment. The revolving line of credit and long-term debt are stated at the carrying value as the stated interest rate approximates market rates currentlyavailable to the Company, which are considered Level 2 inputs.The Company did not have any non-financial assets or non-financial liabilities recognized at fair value on a recurring basis at December 31, 2017 and 2016.Foreign Currency TranslationBalance Sheet accounts of the Company’s Europe subsidiary operations are translated at the exchange rate in effect at the end of each period. Statement ofOperations accounts are translated using the weighted average of the prevailing exchange rates during each period. Gains or losses resulting from foreigncurrency transactions are included in the Company’s Consolidated Statements of Operations under the caption “Other non-operating (income) expense, net”whereas, translation adjustments are reflected in the Consolidated Statements of Comprehensive Income (Loss) under the caption “Foreign currencytranslation adjustment.”Concentration of Credit RiskFinancial instruments that potentially subject the Company to concentrations of credit risk consist principally of investments in cash, cash equivalents andaccounts receivables. The Company is exposed to credit risks and liquidity in the event of default by the financial institutions or issuers of investments inexcess of FDIC insured limits. The Company performs periodic evaluations of the relative credit standing of these financial institutions and limits the amountof credit exposure with any institution.Accounts receivable are unsecured and represent amounts due based on contractual obligations of customers. Our three largest individual customersaccounted for approximately 43% of our gross sales in the aggregate for the year ended December 31, 2017, or individually 16%, 14% and 13%, comparedto 16%, 17% and 17% in 2016 and 14%, 15% and 18% in 2015. In48 Turtle Beach CorporationNotes to Consolidated Financial Statements - (Continued)addition, two customers accounted for 25% and 29% of accounts receivable as of December 31, 2017 and 30% and 27% for December 31, 2016.Concentrations of credit risk with respect to accounts receivable are mitigated by performing ongoing credit evaluations of customers to assess theprobability of collection based on a number of factors, including past transaction experience with the customer, evaluation of their credit history, limiting thecredit extended, and review of the invoicing terms of the contract. In addition the Company has credit insurance in place through a third party insurer againstdefaults by certain domestic and international customers, subject to policy limits. The Company generally does not require customers to provide collateral tosupport accounts receivable. The Company has recorded an allowance for doubtful accounts for those receivables that were determined not to be collectible.Foreign cash balances at December 31, 2017 and 2016 were $0.1 million and $0.2 million, respectively.Segment InformationIn 2014, following the merger, the Company aggregated its two operating segments - Voyetra Turtle Beach (“Headset”) and HyperSound. In light of thesubsequent development and launch of the HyperSound Clear 500P product, the Company evaluated whether its operating segments should continue to beaggregated for reporting purposes and determined that as a result of the new hearing healthcare product, the HyperSound operating segment will no longerhave similar economic characteristics, production processes, clients or methods of distribution. As such, the Company has disclosed the Headset andHyperSound operating segments separately. The entire business is managed by a single management team whose Chief Operating Decision Maker is theChief Executive Officer.Recent Accounting PronouncementsIn May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts withCustomers, which requires entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount thatreflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. The new guidance also requires additionaldisclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments andchanges in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In July 2015, the FASB deferred the effective date of thestandard by one year to annual reporting periods beginning after December 15, 2017 and interim periods within those annual periods. The new standard willrequire certain price concessions and right of return arrangements to be recorded as part of the transaction price determination. The Company has identified,and is in the process of implementing, appropriate changes to its business processes, systems and controls to support recognition and disclosure under thenew standard. The Company will adopt the new standard on January 1, 2018 under the the modified retrospective method of adoption, reflecting thecumulative effect of initially applying the new standard to revenue recognition in the first quarter of 2018. Based on the information we have evaluated todate, we do not believe the standard will materially impact our recognition of revenue from our headset business. That said the Company estimates theadjustment will result in a reduction to the opening balance of retained earnings of approximately $0.5 million.In February 2016, the FASB issued ASU No. 2016-02, Leases, that introduces the recognition of a right-of-use asset, which is an asset that represents thelessee’s right to use, or control the use of, a specified asset for the lease term and, a lease liability, which is a lessee’s obligation to make lease paymentsarising from a lease, measured on a discounted basis for all leases (with the exception of short-term leases). The guidance will be effective for publiccompanies for annual reporting periods beginning after December 15, 2018, and interim periods within those fiscal years with early adoption permitted. TheCompany has not yet selected a transition method or determined the effect on its consolidated financial statements.In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation, which requires excess tax benefits and tax deficiencies, which arisedue to differences between the measure of compensation expense and the amount deductible for tax purposes, to be recorded directly through earnings as acomponent of income tax expense. Previously, these differences were generally recorded in additional paid-in capital and thus had no impact on net income.Additionally, this guidance permits entities to make an accounting policy election for the impact of forfeitures on the recognition of expense for share-basedpayment awards. Forfeitures can be estimated, as allowed under previous standards, or recognized when they occur. The standard was effective for interim andannual reporting periods beginning after December 15, 2016. The Company adopted this standard on January 1, 2017 and the standard did not have amaterial impact on its consolidated financial statements.49 Turtle Beach CorporationNotes to Consolidated Financial Statements - (Continued)In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), which attempts to reduce the existing diversity in practice with respectto reporting the following eight specific cash flow issues: debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instruments or otherdebt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; contingent consideration paymentsmade after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies(including bank-owned life insurance policies); distributions received from equity method investees; beneficial interests in securitization transactions; andseparately identifiable cash flows and application of the predominance principle. This guidance will be effective for the Company on January 1, 2018. TheCompany does not believe the guidance will have a material impact on its consolidated financial statements.In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting to provide clarity andreduce diversity in practice and cost and complexity when applying the guidance to a change to the terms or conditions of a share-based payment award. Theamendments state that an entity will not have to account for the effects of a modification if: (i) the fair value of the modified award is the same immediatelybefore and after the modification; (ii) the vesting conditions of the modified award are the same immediately before and after the modification; and (iii) theclassification of the modified award as either an equity instrument or liability instrument is the same immediately before and after the modification. Theamendments in this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. Early adoption ispermitted, including adoption in any interim period. The adoption of this guidance is not expected to have a material impact upon our financial condition orresults of operations.Note 2. Equity Offering and Private Placement On February 2, 2016, the Company entered into an Underwriting Agreement (the “Underwriting Agreement”) with Oppenheimer & Co. Inc., as representativeof the several other underwriters named therein, relating to an underwritten public offering (the “Offering”) of 5,000,000 shares of our common stock, at aprice to the public of $1.00 per share (the “Offering Price”). Under the terms of the Underwriting Agreement, the Company also granted the underwriters a 30-day option, which was not exercised, to purchase up to an additional 750,000 shares of common stock at the Offering Price less the underwriting discount andestimated offering expenses payable by the Company.In addition, on February 1, 2016, the Company entered into a separate, concurrent, side-by-side private placement of 1,700,000 shares of its common stock ata price of $1.00 per share.The Company received net proceeds from the Offering and a side by side private placement of approximately $6.0 million after deducting the underwritingdiscount and offering expenses of $0.7 million. The Company used all net proceeds from the Offering to pay down amounts outstanding under its workingcapital line of credit, which is consistent with past practice and required under the terms of our Credit Facility and Term Loan Due 2019.Note 3. Fair Value MeasurementThe Company follows a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. This hierarchy requires entities to maximize theuse of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows:•Level 1 — Quoted prices in active markets for identical assets or liabilities.•Level 2 — Observable inputs other than quoted prices included in Level 1, such as quoted prices for markets that are not active, or other inputs thatare observable or can be corroborated by observable market data.•Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.Financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, and debt instruments. As of December 31, 2017 and 2016,the Company has not elected the fair value option for any financial assets and liabilities for which such an election would have been permitted, and therewere no outstanding financial assets and liabilities recorded at fair value on a recurring basis.50 Turtle Beach CorporationNotes to Consolidated Financial Statements - (Continued)The following is a summary of the carrying amounts and estimated fair values of our financial instruments at December 31, 2017 and 2016: December 31, 2017 December 31, 2016 Reported Fair Value Reported Fair Value (in thousands)Financial Assets and Liabilities: Cash and cash equivalents$5,247 $5,247 $6,183 $6,183Credit Facility$38,467 $38,467 $35,905 $35,905Term Loans$11,721 $11,329 $14,367 $14,281Subordinated Debt$21,911 $22,442 $19,403 $18,569Cash equivalents are stated at amortized cost, which approximates fair value as of the consolidated balance sheet dates, due to the short period of time tomaturity; and accounts receivable and accounts payable are stated at their carrying value, which approximates fair value due to the short time to the expectedreceipt or payment. The carrying value of the Credit Facility and Term Loan Due 2018 equals fair value as the stated interest rate approximates market ratescurrently available to the Company, which are considered Level 2 inputs. The fair values of our Term Loan Due 2019 and Subordinated Debt are based uponan estimated market value calculation that factors principal, time to maturity, interest rate and current cost of debt, which is considered a Level 3 input.Note 4.

The acquired intangible assets relating to customerrelationships and non-compete agreements are being amortized over an estimated useful life of thirteen years with the amortization being included withinsales and marketing expense.In January 2014, the merger between VTBH and Turtle Beach (f/k/a Parametric Sound Corporation) was completed. The acquired intangible assets relating todeveloped technology, customer relationships and trade name were subject to amortization. During 2016, the Company completed an impairment analysisunder an income approach that reflected recent events in connection with the strategic options exploration, including the transition to a licensing businessmodel. Based on additional information such as sustained slower than anticipated sales volumes in the HyperSound business and certain plans to reduceoperating costs to align with current revenues, the Company materially revised certain revenue growth and margin assumptions based on estimates of futureoperations. As a result, in conjunction with the completion of the second step of the Company's goodwill impairment analysis, we recorded a $32.1million impairment charge related to the developed technology, in-process research and development and trade names, which is included as a component ofgoodwill and intangible asset impairment.Amortization expense related to definite lived intangible assets of $0.3 million, $4.1 million and $2.0 million for the years ended December 31, 2017, 2016and 2015, respectively.53 Turtle Beach CorporationNotes to Consolidated Financial Statements - (Continued)As of December 31, 2017, estimated annual amortization expense related to definite lived intangible assets in future periods is as follows: (in thousands)2018$3662019307202025820212172022182Thereafter293Total$1,623Note 7.

In connection with the Term Loan Due 2019 and Amended Notes, the Company incurred $5.3 million of financing costs, including $2.0 millionrelated to the fair value of the warrants issued recorded as debt discount, which has been deferred and will be recognized over the term of the respectiveagreements.54 Turtle Beach CorporationNotes to Consolidated Financial Statements - (Continued)Maturities as of December 31, 2017 for each of the next five years are as follows: (in thousands)2018$4,173201929,459Thereafter—Total$33,632Revolving Credit FacilityOn March 31, 2014, Turtle Beach and certain of its subsidiaries entered into a new asset-based revolving credit agreement, most recently amended October31, 2016 (“Credit Facility,”) with Bank of America, N.A., as Agent, Sole Lead Arranger and Sole Bookrunner, which replaced the then existing loan andsecurity agreement. The Credit Facility, which expires on March 31, 2019, provides for a line of credit of up to $60 million inclusive of a sub-facility limit of$10 million for TB Europe, a wholly owned subsidiary of Turtle Beach. The Credit Facility may be used for working capital, the issuance of bank guarantees,letters of credit and other corporate purposes.The Company and its subsidiaries are required to comply with various customary covenants under the terms of the Credit Facility including, (i) maintainingminimum EBITDA in each trailing twelve month period, (ii) maintaining a Consolidated Leverage Ratio to be measured on the last day of each month, (iii)maintaining certain cash flow levels, in the aggregate and with respect to its HyperSound segment, during each rolling four week period beginning with theperiod ended October 31, 2016 through December 31, 2018, (iv) limitation on capital expenditures in excess of $5 million in each of the years endingDecember 31, 2018 and 2019 and (v) in the event the Company’s availability is less than certain specified amounts, obtaining additional funding from theissuance of a subordinated promissory note provided by SG VTB (the “Promissory Note”).The maximum credit availability for loans and letters of credit under the Credit Facility is governed by a borrowing base determined by the application ofspecified percentages to certain eligible assets, primarily eligible trade accounts receivable and inventories, and is subject to discretionary reserves andrevaluation adjustments.Amounts outstanding under the Credit Facility bear interest at a rate equal to either a rate published by Bank of America or the LIBOR rate, plus in each case,an applicable margin, which is between 1.00% to 1.50% for U.S. base rate loans and between 2.00% to 2.50% for U.S. LIBOR loans and U.K. loans. As ofDecember 31, 2017, interest rates for outstanding borrowings were 5.75% for base rate loans and 3.74% for LIBOR rate loans. In addition, Turtle Beach isrequired to pay a commitment fee on the unused revolving loan commitment at a rate ranging from 0.25% to 0.50%, and letter of credit fees and agent fees.If certain availability thresholds are not met, meaning that the Company does not have receivables and inventory which are eligible to borrow on under theCredit Facility in excess of amounts borrowed, the Credit Facility requires the Company and its restricted subsidiaries to maintain a fixed charge coverageratio. The fixed charge ratio is defined as the ratio, determined on a consolidated basis for the most recent four fiscal quarters, of (a) EBITDA minus capitalexpenditures, excluding those financed through other instruments, and cash taxes paid, and (b) Fixed Charges defined as the sum of cash interest expenseplus scheduled principal payments. The current fixed charge coverage ratio of at least 1.15 to 1.00 on the last day of each month while a Covenant TriggerPeriod (as defined in the Credit Facility) is in effect will become effective again after the Company has complied with such ratio for six consecutive months.The Credit Facility also contains affirmative and negative covenants that, subject to certain exceptions, limit our ability to take certain actions, including ourability to incur debt, pay dividends and repurchase stock, make certain investments and other payments, enter into certain mergers and consolidations,engage in sale leaseback transactions and transactions with affiliates and encumber and dispose of assets. Obligations under the Credit Facility are secured bya security interest and lien upon substantially all of the Company's assets.As of December 31, 2017, the Company was in compliance with all the amended financial covenants, and excess borrowing availability was approximately$9.7 million, net of the outstanding Term Loan Due 2018 (as defined below) that is considered to be an additional outstanding amount under the CreditFacility.55 Turtle Beach CorporationNotes to Consolidated Financial Statements - (Continued)Term LoansTerm Loan Due 2018On December 29, 2014, the Company amended the Credit Facility with Bank of America to enter in to an additional loan (the “Term Loan Due 2018”) for therepayment of $7.7 million of then existing subordinated debt and accrued interest. The Term Loan Due 2018 resulted in modified financial covenants whileit is outstanding, will bear interest at a rate of LIBOR for the applicable interest period plus 5% and will be repaid in equal monthly installments beginningon April 1, 2015 and ending on October 1, 2018, reflecting a six month waiver. Amounts so repaid are recognized by lowering the balance of the term loantranche and increasing the lower interest rate base revolver amount, with no net impact on borrowing availability.Term Loan Due 2019On July 22, 2015, the Company and its subsidiaries, entered into a term loan, guaranty and security agreement (the “Term Loan Due 2019”) with CrystalFinancial LLC, as agent, sole lead arranger and sole bookrunner, Crystal Financial SPV LLC and the other persons party thereto (“Crystal”), which providesfor an aggregate term loan commitment of $15 million that bears interest at a rate per annum equal to the 90-day LIBOR rate plus 10.25%. Under the terms ofthe Term Loan Due 2019, the Company is required to make payments of interest in arrears on the first day of each month beginning August 1, 2015 and willrepay the principal in monthly payments beginning January 1, 2016, inclusive of a nine month waiver, with a final payment on June 28, 2019, the maturitydate.The Term Loan Due 2019 is secured by a security interest in substantially all of the Company and each of its subsidiaries' working capital assets and issubject to the first-priority lien of Bank of America , N.A., as agent, under the Credit Facility, other than with respect to equipment, fixtures, real propertyinterests, intellectual property, intercompany property, intercompany indebtedness, equity interest in their subsidiaries, and certain other assets specified inan inter-creditor agreement between Bank of America and Crystal.The Company and its subsidiaries are required to comply with various customary covenants including, (i) maintaining minimum EBITDA (as defined in theTerm Loan Due 2019) in each trailing twelve month period, (ii) maintaining a Consolidated Leverage Ratio (as defined in the Term Loan Due 2019) to bemeasured on the last day of each month, (iii) maintaining certain cash flow levels, in the aggregate and with respect to its HyperSound segment, during eachrolling four week period beginning with the period ended October 31, 2016 through December 31, 2018, (iv) limitation on capital expenditures in excess of$5 million in each of the years ending December 31, 2018 and 2019, (v) in the event the Company’s availability is less than certain specified amounts,obtaining additional funding from the issuance of a subordinated promissory note provided by SG VTB (the “Promissory Note”), and (vi) restrictions on theCompany’s and its subsidiaries ability to prepay its subordinated notes, pay dividends, incur debt, create or suffer liens and engage in certain fundamentaltransactions. The agreement permits certain equity holders of the Company to contribute funds to the Company to cure certain financial covenant defaults.The Term Loan Due 2019 contains customary representations, mandatory prepayment events and events of default, including defaults triggered by the failureto make payments when due, breaches of covenants and representations, material impairment in the perfection of Crystal’s security interest in the collateraland events related to bankruptcy and insolvency of the Company and its subsidiaries. Upon an event of default, Crystal may declare all outstandingobligations immediately due and payable (along with a prepayment fee), a default rate of an additional 2.0% may be applied to amounts outstanding andmay take other actions including collecting or taking such other action with respect to the collateral pledged in connection with the term loan.On November 2, 2015, the Company entered into an amendment to the Term Loan Due 2019 to, among other things, provide that upon receipt all theproceeds from the future issuance of subordinated notes will immediately be used to prepay outstanding principal in an amount equal to $2.5 million.As of December 31, 2017, the Company was in compliance with all the amended financial covenants, and the outstanding principal balance was $9.8 million.56 Turtle Beach CorporationNotes to Consolidated Financial Statements - (Continued)Subordination AgreementOn November 16, 2015, as a condition precedent to the Company's lenders permitting the Company to enter into certain subordinated notes, the Companyentered into a subordination agreement with and between Bank of America and Crystal, pursuant to which the parties agreed that the Company's obligationsunder any such notes would be subordinate in right of payment to the payment in full of all the Company’s obligations under the Credit Facility and TermLoan Due 2019.Subordinated Notes - Related PartyOn April 23, 2015, the Company issued a $5.0 million subordinated note (the “April Note”) to SG VTB Holdings, LLC, the Company’s largest stockholder(“SG VTB”). The April Note was issued with an interest rate of (i) 10% per annum for the first year and (ii) 20% per annum for all periods thereafter, withinterest accruing and being added to the principal amount of the note quarterly.On May 13, 2015, the Company issued subordinated notes (the “May Notes”) with an aggregate principal amount of $3.8 million to SG VTB, and a trustaffiliated with Ronald Doornink, the Chairman of the Company's board of directors (the “Board”). The May Notes were issued with an interest rate of 10% perannum until the maturity date of the May Notes (which was August 13, 2015 but could be extended up to two additional 90 day periods upon the writtenagreement of the Company and the noteholder), with interest accruing and being added to the principal amount of the May Notes quarterly. Following thematurity date, the interest rate would have increased to 20% per annum.On June 17, 2015, the Company issued a subordinated note (the “June Note”) with an aggregate principal amount of $3.0 million to SG VTB. The June Notewas issued at an interest rate of 10% per annum until the maturity date of the June Note (which was September 17, 2015 but could be extended up to twoadditional 90 day periods upon the written agreement of the Company and the noteholder), with interest accruing and being added to the principal amount ofthe June Note quarterly. Following the maturity date, the interest rate would have increased to 20% per annum. In addition, the Company had the option torequest that SG VTB make, in SG VTB’s sole discretion, additional advances from time to time up to an aggregate principal amount of $15.0 million. Prior tothe amendment (see below), after an additional advance of $6.0 million on July 8, 2015, $9.0 million was outstanding under the June Note.Concurrently with the completion of the Term Loan Due 2019, the Company amended and restated each of its outstanding subordinated notes (the“Amended Notes”). The obligations of the Company under the Amended Notes is subordinate and junior to the prior payment of amounts due under theCredit Facility and Term Loan Due 2019. In addition, the stated maturity date of the Amended Notes was extended to September 29, 2019, subject toacceleration in certain circumstances, such as a change of control in the Company. The Amended Notes bear interest at a rate per annum equal to LIBOR plus10.5% and shall be paid-in-kind by adding the amount to the principal amount due. Further, as consideration for the concessions in the Amended Notes, theCompany issued warrants to purchase 1.7 million shares of the Company’s common stock at an exercise price of $2.54 per share.On November 16, 2015, the Company issued a $2.5 million subordinated note (the “November Note”) to SG VTB, the proceeds of which, as set forth in theamendment to the Term Loan Due 2019, were applied against the outstanding balance of the Term Loan Due 2019. The November Note will bear interest at arate of 15% per annum until its maturity date, which is September 29, 2019, and is subordinated to all senior debt of the Company.In consideration of the credit extended under the November Note, VTB and VTBH entered into a Third Lien Continuing Guaranty, (as amended, the “ThirdLien Guaranty”), under which they guarantee and promise to pay to Stripes, any and all obligations of the Company under the November Note. To secure ourobligations under the November Note and the Third Lien Guaranty, the Company entered into a Third Lien Security Agreement, dated as of November 16,2015, pursuant to which Stripes was granted a security interest upon all property of the VTB and VTBH until the payment in full of the Subordinated Note orthe release of the guarantee or collateral, as applicable. Concurrent with entering into the November Note and Third Lien Guaranty, the Company also issuedto SG VTB a warrant to purchase 1.4 million shares of the Company’s common stock at an exercise price of $2.00 per share to SG VTB.On October 31, 2016, in connection with certain amendments to the Credit Facility and Term Loan Due 2019, the Company and SG VTB entered into thePromissory Note, which states that in the event the Company’s availability under the Credit Facility is less than certain specified amounts, the Company may,upon request, at any time until September 29, 2019 require that SG VTB provide a $2 million subordinated loan. Upon issuance, the loan would bear interestat a rate of either (i) LIBOR plus57 Turtle Beach CorporationNotes to Consolidated Financial Statements - (Continued)10.5% per annum or (ii) 12.0%, dependent upon the Company’s compliance with certain financial covenants and would be subordinated to all senior debt ofthe Company.In addition, under the terms of the Promissory Note, if and when the funding occurs, as additional consideration the Company would issue to SG VTB awarrant, exercisable for a period of ten years beginning on the date of issuance, to purchase an amount of shares of the Company’s common stock equal to2.4% of the Company’s then fully diluted shares outstanding at an exercise price equal to the closing price on that date. The warrant would not entitle theholder to any voting rights or other rights as a stockholder of the Company prior to exercise.SG VTB is an affiliate of Stripes Group LLC (“Stripes”), a private equity firm focused on internet, software, healthcare IT and branded consumer productsbusinesses. Kenneth A. Fox, one of our directors, is the managing general partner of Stripes and the sole manager of SG VTB and Ronald Doornink, ourChairman of the Board, is an operating partner of Stripes.March 2018 AmendmentOn March 5, 2018, the Company amended and restated its existing Credit Facility, Term Loan Due 2019 and subordinated notes. The amended agreements,among other things, (i) reduce the applicable margin on borrowings, (ii) modify existing financial covenants under the credit facility and term loan withfinancial maintenance covenants including a customary consolidated leverage ratio, fixed charge coverage ratio and certain limitations on capitalexpenditures and disbursementsand (iii) provide for the ability to borrow additional terms loans in the future to be used for general working capital purposes (including, the ability to use thedelayed draw term loans to pay down the principal amount of the subordinated notes, subject to the satisfaction of certain conditions described therein.The Credit Facility, which extended a line of credit of up to $60 million to March 5, 2023, reduced the applicable margin to 0.50% to 1.25% for base rateloans and 1.50% to 2.25% for LIBOR loans. The Term Loan Due 2019 provides for an aggregate term loan facility of $12.5 million and extends the maturitydate to March 2023, including a delayed draw commitment, and bears interest at a rate per annum equal to the 90-day LIBOR rate plus 6.75%. Thesubordinated notes will bear in-kind interest at a rate of (i) LIBOR plus 9.1% per annum for the first twenty-four months (or six months (or such date datedprovided that the amount of such note is reduced by a specified amount by the six month anniversary of the restatement effective date) with respect to theNovember Note) and (ii) LIBOR plus 10.5% per annum (or 15.0% with respect to the November Note if the prepayment described above does not occur)thereafter until September 2024.Note 8.

The “Tax Cuts and Jobs Act,” enacted in December 2017, reduces the US federal corporate tax rate from 35% to 21%effective January 1, 2018. Consequently, we have re-measured our deferred tax assets and liabilities based on the rates at which they are expected to reversein the future, which is generally 21%. On December 22, 2017, Staff Accounting Bulletin No. 118 (“SAB 118”) was issued to address the application of U.S.GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detailto complete the accounting for certain income tax effects of the Act. In accordance with SAB 118, the Company recorded a decrease in its net deferred taxassets of $10.5 million with a corresponding decrease to its valuation allowance to account for this rate reduction. The Act also requires a deemed repatriationof foreign earnings and profits, determined as of either November 2, 2017 or December 31, 2017, whichever amount is greater. As such, the Company reporteda deemed repatriation of foreign earnings totaling $0.5 million as of December 31, 2017 related to its European subsidiary. The Company considers theearnings of certain non-U.S. subsidiaries to be indefinitely reinvested outside the United States and the current plans do not demonstrate a need to repatriatethem to fund our U.S. operations.59 Turtle Beach CorporationNotes to Consolidated Financial Statements - (Continued)The tax effects of significant items comprising the Company’s deferred tax assets/(liabilities) are as follows: December 31, 2017 December 31, 2016 (in thousands)Allowance for doubtful accounts$16 $52Inventories1,028 3,407Employee benefits2,347 3,754Net operating loss14,766 19,246Unrecognized tax benefits676 649Depreciation and amortization(54) 357Intangible assets— 209Other1,085 1,222 19,864 28,896Valuation allowance(19,502) (28,353)Net deferred tax assets (liabilities)$362 $543At December 31, 2017, the Company has $57.4 million of net operating loss carryforwards and $30.6 million of state net operating loss carryforwards, whichwill begin to expire in 2029. An ownership change occurred on January 15, 2014, and$12.7 million of federal net operating losses included in the above are pre-change losses subject to Section 382 of the Internal Revenue Code of 1986, asamended. The Company believes, based on the estimated Section 382 limitation and the net operating loss carryforward period, that the pre ownershipchange net operating losses can be fully utilized in future years if there is sufficient taxable income in such carryforward period.The realization of deferred tax assets depends on the generation of future taxable income during the periods in which those temporary differences aredeductible. During 2015, as a result of cumulative losses in recent years primarily due to incremental costs associated with the console transition, acquisitioncosts and initial investments in the HyperSound business, the Company concluded that a full valuation allowance is required on its net domestic deferred taxassets. However, the Company believes there is sufficient evidence to support the utilization of the Company’s international net deferred tax assets totaling$0.4 million and, therefore, no valuation allowance has been set-up against these assets.In 2017, due to changes in the reporting of stock compensation, the Company’s previously unrecognized excess tax benefit related to the exercise ofnonqualified stock options totaling $2.2 million was recognized in deferred tax assets. This increase to deferred tax assets was fully offset by the Company’svaluation allowance.A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows: December 31, 2017 December 31, 2016 (in thousands)Gross unrecognized tax benefit, beginning of period$1,468 $1,468Additions based on tax positions related to the current year— —Decreases based on tax positions in a prior period— —Gross unrecognized tax benefit, end of period$1,468 $1,468The Company recognizes only those tax positions that meet the more-likely-than-not recognition threshold, and establish tax reserves for uncertain taxpositions that do not meet this threshold. To the extent these unrecognized tax benefits are ultimately recognized, approximately $1.5 million will impact theCompany’s effective tax rate in a future period. Interest and penalties associated with income tax matters are included in the provision for income taxes. As ofDecember 31, 2017, the Company had uncertain tax positions of $2.3 million, inclusive of $0.8 million of interest and penalties.60 Turtle Beach CorporationNotes to Consolidated Financial Statements - (Continued)The Company files U.S., state and foreign income tax returns in jurisdictions with various statutes of limitations.

Preferred StockSeries B Redeemable Preferred StockIn September 2010, VTBH issued 1,000,000 shares of non-voting Series B Redeemable Preferred Stock (“Preferred Stock”) with a fair value of $12.4 million.We are required to redeem the Preferred Stock on the earlier to occur of September 28, 2030 or the occurrence of a liquidation event at its original issue priceof $12.425371 per share plus any accrued but unpaid dividends. Dividends are cumulative and accrue at a rate of 8.0% per annum, compounded quarterly,and payable as and when declared by the Board of Directors. The Preferred Stock does not contain any conversion rights.A liquidation event is defined as any acquisition of the Company by means of merger or other form of corporate reorganization in which the outstandingshares of the corporation are exchanged for securities or other consideration issued, or caused to be issued, by the acquiring corporation or its subsidiary(other than a reincorporation transaction) or a sale of all or substantially all of the assets of the corporation.For the years ended December 31, 2017, 2016, and 2015, the Company recognized $1.4 million, $1.3 million and $1.2 million, respectively, of interestexpense on the Preferred Stock. The redemption value was $18.9 million and $17.5 million as of December 31, 2017 and 2016, respectively. The Companyhas recorded the Preferred Stock as a non-current liability due to its mandatory redemption provisions for all periods presented.There were no dividends declared during the years ended December 31, 2017, 2016 and 2015.As of December 31, 2017, 2016, and 2015, 1,000,000 shares of Series B Redeemable Preferred Stock are authorized, issued and outstanding.61 Turtle Beach CorporationNotes to Consolidated Financial Statements - (Continued)Note 10.

Stock-Based CompensationOn October 30, 2013 the Board of Directors adopted, and on December 27, 2013 the stockholders approved, the 2013 Stock-Based Incentive CompensationPlan (the “2013 Plan”), that became effective upon consummation of the Merger on January 15, 2014. Our stock-based compensation program is a broad-based program designed to attract and retain employees while also aligning employees’ interests with the interests of our shareholders. In addition, membersof our Board of Directors participate in our stock-based compensation program in connection with their service on our board.Stock option awards outstanding under the Company’s Plans are time-based and granted at exercise prices which are equal to the market value of theCompany’s common stock on the grant date (determined in accordance with the applicable Plan), and expire no later than ten years of the date of grant, butonly to the extent they have vested. The options generally vest as specified in the option agreements subject, in some instances, to acceleration in certaincircumstances. The restrictions on restricted stock generally lapse over a three-year period from the date of the grant. In the event a participant terminatesemployment with the Company, any vested stock options and any restricted stock still subject to restrictions are generally forfeited if they are not exercisedwithin 90 days.The following table presents the stock activity and the total number of shares available for grant as of December 31, 2017: (in thousands)Balance at December 31, 20162,261Options granted(1,751)Restricted Stock granted(167)Forfeited/Expired shares added back1,206Balance at December 31, 20171,549Total estimated stock-based compensation expense for employees and non-employees, related to all of the Company's stock-based awards, was comprised asfollows: Year Ended December 31, 2017 2016 2015 (in thousands)Cost of revenue$(66) $557 $889Selling and marketing100 90 320Research and development232 561 784General and administrative1,164 2,752 3,904Total stock-basedcompensation$1,430 $3,960 $5,897Forfeitures on option grants are estimated at 10% based on evaluation of historical and expected future turnover for non-executives and 0% based forexecutives. Stock-based compensation expense was recorded net of estimated forfeitures, such that expense was recorded only for those stock-based awardsthat are expected to vest. The Company reviews this assumption periodically and will adjust it if it is not representative of future forfeiture data and trendswithin employee types (executive vs. non-executive).None of the Company's stock options were exercised for the year ended December 31, 2017 and 2016. The associated tax benefit recognized in theConsolidated Statements of Operations for the fiscal years ended December 31, 2015 was approximately $2.1 million. In 2017, due to changes in thereporting of stock compensation, the Company’s previously unrecognized excess tax benefit related to the exercise of nonqualified stock options totaling$2.2 million was recognized in deferred tax assets.63 Turtle Beach CorporationNotes to Consolidated Financial Statements - (Continued)Stock Option Activity Options Outstanding Number ofSharesUnderlyingOutstandingOptions Weighted-AverageExercisePrice Weighted-AverageRemainingContractualTerm AggregateIntrinsicValue (In years) Outstanding at December 31, 20166,381,447 $1.9 7.37 $20,033Granted1,750,674 0.68 Exercised— — Forfeited(1,171,794) 2.17 Outstanding at December 31, 20176,960,327 $1.55 6.64 $6Vested and expected to vest at December 31, 20176,734,078 $1.59 6.58 $4Exercisable at December 31, 20174,081,307 $1.95 5.30 $—Aggregate intrinsic value represents the difference between the estimated fair value of the underlying common stock and the exercise price of outstanding, in-the-money options. There was no aggregate intrinsic value of options exercised for the year ended December 31, 2017.As of December 31, 2017, total unrecognized compensation cost related to non-vested stock options granted to employees was $1.3 million, which isexpected to be recognized over a remaining weighted average vesting period of 2.9 years.Determination of Fair ValueOption valuation models require the input of highly subjective assumptions, including expected stock price volatility. The Black-Scholes option pricingmodel was developed for use in estimating the fair value of traded options, which have no vesting restrictions and are fully transferable. The fair value ofoptions granted under the Company’s Plans was estimated on the date of grant using the Black-Scholes option pricing model with the followingassumptions: Year Ended December 31, 2017 2016 2015 (in thousands)Expected term (in years)6.1 6.1 6.1Risk-free interest rate1.9% - 2.3% 1.1% - 2.3% 1.5% - 1.9%Expected volatility38.7%- 41.1% 40.7% - 42.2% 40.8% - 47.1%Dividend rate0% 0% 0%Each of these inputs is subjective and generally requires significant judgment to determine. The risk-free rate is based on a zero-coupon U.S. Treasury rate ineffect at the time of grant with maturity dates that coincide with the expected life of the options. The expected life of the options is based on a simplifiedweighted average taking into account the vesting conditions and contractual life of the award. Since the Company has a limited trading history for itscommon stock, the expected volatility was derived from the historical stock volatilities of several unrelated public companies within the Company’s industrythat are considered to be comparable to the Company’s business over a period equivalent to the expected term of the stock option grants.The weighted average grant date fair value of options granted during the years ended December 31, 2017, 2016 and 2015 was $0.29, $0.48 and $0.88,respectively. The total estimated fair value of employee options vested during the years ended December 31, 2017, 2016 and 2015 was $1.3 million, $2.4million and $3.0 million, respectively.64 Turtle Beach CorporationNotes to Consolidated Financial Statements - (Continued)Restricted Stock Activity Shares Weighted AverageGrant Date Fair ValuePer ShareNonvested restricted stock at December 31, 2016135,705 $1.84Granted166,665 0.90Vested(91,002) 2.06Forfeited(43,903) 1.16Nonvested restricted stock at December 31, 2017167,465 0.96As of December 31, 2017 total unrecognized compensation cost related to the nonvested restricted stock awards granted was $0.2 million, which is expectedto be recognized over a remaining weighted average vesting period of 0.3 years.Stock WarrantsIn connection with and as consideration for the concessions in the Amended Notes, the Company issued to SG VTB and a trust affiliated with RonaldDoornink warrants to purchase 1.7 million shares of the Company’s common stock at an exercise price of $2.54 per share. The warrants are exercisable for aperiod of five years beginning on the date of issuance, July 22, 2015. The exercise price and the number of shares of Common Stock purchasable are subjectto standard anti-dilution adjustments and do not carry any voting rights or other rights as a stockholder of the Company prior to exercise. The shares issuableupon exercise are also subject to the “demand” and “piggyback” registration rights set forth in the in the Company’s Stockholder Agreement, dated August 5,2013, as amended July 10, 2014.In connection with the November Note, the Company issued a warrant to purchase 1.4 million shares of the Company’s common stock at an exercise price of$2.00 per share to SG VTB. The exercise price and the number of shares are subject to standard anti-dilution adjustments and do not carry any voting rights asa stockholder of the Company prior to exercise. The warrant is exercisable for a period of ten years beginning on the date of issuance and does not entitle theholder to any voting rights or other rights as a stockholder of the Company prior to exercise.The warrants meet the requirements for classification within equity as warrants entitle the holder to purchase a stated amount of shares of common stock at afixed exercise price that are not puttable (either the warrant or the shares) to the Company or redeemable for cash.Phantom Equity ActivityIn November 2011, VTBH adopted a 2011 Phantom Equity Appreciation Plan ("the Appreciation Plan") that covers certain employees, consultants, anddirectors of VTBH (“Participants”) who are entitled to phantom units, as applicable, pursuant to the provisions of their respective award agreements. TheAppreciation Plan is shareholder-approved, which permits the granting of phantom units to VTBH’s Participants of up to 1,500,000 units. These units are notexercisable or convertible into shares of common stock but give the holder a right to receive a cash bonus equal to the appreciation in value between theexercise price and value of common stock at the time of a change in control event as defined in the plan.As of December 31, 2017 and 2016, 714,347 phantom units at a weighted-average exercise price of $0.93 have been granted and are outstanding. Becausethese phantom units are not exercisable or convertible into common shares, said amounts and exercise prices were not subject to the exchange ratio providedby the Merger agreement. As of December 31, 2017, compensation expense related to the Appreciation Plan units remained unrecognized because a changein control, as defined in the plan, had not occurred and is not anticipated by the Company. In July 2015, the Appreciation Plan was terminated as to newgrants, but vested and unvested phantom units will continue.65 Turtle Beach CorporationNotes to Consolidated Financial Statements - (Continued)Note 12.

Commitments and ContingenciesLitigationThe Company is subject to various legal proceedings and claims that arise in the ordinary course of its business. Although the amount of any liability thatcould arise with respect to these actions cannot be determined with certainty, in the Company’s opinion, any such liability will not have a material adverseeffect on its consolidated financial position, consolidated results of operations or liquidity.Shareholders Class Action: On August 5, 2013, VTBH and the Company (f/k/a Parametric) announced that they had entered into the Merger Agreementpursuant to which VTBH would acquire an approximately 80% ownership interest and existing shareholders would maintain an approximately 20%ownership interest in the combined company. Following the announcement, several shareholders filed class action lawsuits in California and Nevada seekingto enjoin the Merger. The plaintiffs in each case alleged that members of the Company’s Board of Directors breached their fiduciary duties to the shareholdersby agreeing to a Merger that allegedly undervalued the Company. VTBH and the Company were named as defendants in these lawsuits under the theory thatthey had aided and abetted the Company's Board of Directors in allegedly violating their fiduciary duties. The plaintiffs in each case alleged that members ofthe Company’s Board of Directors breached their fiduciary duties to the shareholders by agreeing to a Merger that allegedly undervalued the Company.VTBH and the Company were named as defendants in these lawsuits under the theory that they had aided and abetted the Company's Board of Directors inallegedly violating their fiduciary duties. The plaintiffs in both cases sought a preliminary injunction seeking to enjoin closing of the Merger, which byagreement was heard by the Nevada court with the California plaintiffs invited to participate. On December 26, 2013, the court in the Nevada cases deniedthe plaintiffs’ motion for a preliminary injunction. Following the closing of the Merger, the Nevada plaintiffs filed a second amended complaint, which madeessentially the same allegations and sought monetary damages as well as an order rescinding the Merger. The California plaintiffs dismissed their actionwithout prejudice, and sought to intervene in the Nevada action, which was granted. Subsequent to the intervention, the plaintiffs filed a third amendedcomplaint, which made essentially the same allegations as prior complaints and sought monetary damages. On June 20, 2014, VTBH and the Companymoved to dismiss the action, but that motion was denied on August 28, 2014. That denial was appealed to the Nevada Supreme Court. On September 14,2017, a unanimous en banc panel of the Nevada Supreme Court granted defendants’ petition for writ of mandamus and ordered the trial court to dismiss thecomplaint, but did provide a limited basis upon which plaintiffs could seek to amend their complaint. Plaintiffs filed an amended complaint on December 1,2017, and motions to dismiss were filed on January 2, 2018. The court will hear those motions on March 12, 2018. The Company believes that the plaintiffs’claims against it are without merit.Dr. John Bonanno Complaint: On February 18, 2015, Dr. John Bonanno, a minority shareholder of Series B Preferred Stock of VTBH, filed a complaint inDelaware Chancery Court alleging breach of contract against VTBH. According to the complaint, the Merger purportedly triggered a contractual obligationfor VTBH to redeem Dr. Bonanno's preferred stock. Dr. Bonanno requests a declaratory judgment stating that he is entitled damages including a redemptionof his stock for the redemption value of $15.1 million (equal to the original issue price of his stock plus accrued dividends) as well as other costs andexpenses. On February 8, 2016, the Delaware Chancery Court granted VTBH's motion to dismiss for improper venue, and Dr. Bonnano's complaint wasdismissed without prejudice. In January of 2017, Dr. Bonanno filed a complaint in New York state court alleging breach of contract against VTBH andseeking a declaratory judgment that he is entitled to damages and specific performance, including redemption of his stock. VTBH answered the complaint onMarch 7, 2017. At the order of the Court, the parties filed cross-motions for summary judgment on March 31, 2017, on the sole question of whether theMerger was a defined event in the purported contract entitling Dr. Bonnano to redemption of his shares. The cross-motions for summary judgment were fullybriefed and heard on July 6, 2017. On September 1, 2017, the Court denied Defendant’s motion for67 Turtle Beach CorporationNotes to Consolidated Financial Statements - (Continued)summary judgment and granted Plaintiff’s motion for partial summary judgment. On October 5, 2017, a status conference was held that set a pre-trial schedulesuch that all merits and expert discovery will conclude on May 3, 2018 and a trial readiness conference will be held on May 4, 2018. On October 11, 2017,VTBH filed a motion to reargue plaintiff’s motion defenses to liability remain available, which was granted. On the same day, Defendant filed a notice ofappeal of the Court’s decision on summary judgment in its entirety. The plaintiff’s ability to recover any damages is subject to certain limitations, including,but not limited to, legally available funds. VTBH maintains that the Merger did not trigger any obligation to redeem Mr. Bonanno's preferred stock.Commercial Dispute: On July 20, 2016, Bigben Interactive S.A. (“BigBen”) filed a statement of claim before the Regional Court of Berlin, Germany againstVTB, which statement of claim was formally serviced upon VTB on June 28, 2017. The statement of claim alleges that VTB’s termination of a distributionagreement by and between BigBen and VTB breached the terms thereof and was invalid, and that BigBen is entitled to damages amounting to damagesamounting to €5.0 million plus accrued interests thereon plus certain additional damages as a result of such invalid termination. VTB filed its statement ofdefense with the court on September 21, 2017. VTB maintains that its termination of the agreement was valid and that BigBen’s claims against it are withoutmerit. VTB's statement of defense was submitted to the plaintiff and the court has granted the option to submit a further written statement in reply to thestatement of defense.The Company will continue to vigorously defend itself in the foregoing matters. However, litigation and investigations are inherently uncertain.Accordingly, the Company cannot predict the outcome of these matters. The Company has not recorded any accrual at December 31, 2017 for contingentlosses associated with these matters based on its belief that losses, while possible, are not probable. Further, any possible range of loss cannot be reasonablyestimated at this time. The unfavorable resolution of these matters could have a material adverse effect on the Company’s business, results of operations,financial condition or cash flows. The Company is engaged in other legal actions not described above arising in the ordinary course of its business and, whilethere can be no assurance, believes that the ultimate outcome of these other legal actions will not have a material adverse effect on its business, results ofoperations, financial condition or cash flows.Operating LeasesThe Company leases office and warehouse spaces under operating leases that provide for future minimum rental lease payments under non-cancelableoperating leases as of December 31, 2017, are as follows: (in thousands)2018$9842019789202050520212812022104Total$2,663WarrantiesThe Company warrants products against certain manufacturing and other defects.

Upon receiving the reports, the Company promptly stoppedshipping any units of the XO FOUR Stealth headsets and notified our retail customers to stop sales pending the results of the Company’s investigation. Anoutside laboratory engaged by the Company identified the substance as mold. In cooperation with the U.S. Consumer Product Safety Commission (“CPSC”),the Company is voluntarily recalling certain units of the headsets. As of December 31, 2017 and the date of this report, the Company has not received noticeof any law suits against the Company in connection with the recall and is working with the contract manufacturer to collect reimbursement for certain relatedcosts.On February 3, 2016, the Company notified CPSC promptly upon discovery that a vendor had mistakenly shipped certain recalled headsets to fill onlineorders. The Company has attempted to notify directly each of the affected purchasers to instruct them to participate in the recall. By letter dated August 23,2017, CPSC staff notified the Company that the staff does not intend to seek penalties against the Company at this time for the post-recall sale, offer for saleor distribution in commerce of recalled headsets.Note 14.

In makingthis assessment, we used the framework and criteria established in Internal Control—Integrated Framework (2013), issued bythe Committee of Sponsoring Organizations of the Treadway Commission. Based on our assessment using those criteria, weconcluded that, as of December 31, 2017, our internal control over financial reporting was effective.At the conclusion of the period covered by this Annual Report on Form 10-K, we carried out an evaluation, under thesupervision of our Chief Executive Officer (our principal executive officer, or PEO) and our Chief Financial Officer (ourprincipal financial officer, or PFO), of the effectiveness of the design and operation of our disclosure controls and procedures.Based upon that evaluation, our PEO and PFO concluded that our disclosure controls and procedures, as defined in Rule13a-15(e) of the Exchange Act, were effective as of December 31, 2017.Management’s Report on Internal Control over Financial ReportingOur management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) or 15d-15(f)of the Exchange Act). Our internal control system was designed to provide reasonable assurance to our management and Board of Directors regarding thepreparation and fair presentation of published financial statements. All internal control systems, no matter how well designed, have inherent limitations. Because of these inherent limitations, internal control over financialreporting can provide only reasonable assurance with respect to financial statement preparation and presentation, and may not prevent or detectmisstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because ofchanges in conditions, or that the degree of compliance with the policies or procedures may deteriorate. We assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2017. In making this assessment, we used theframework and criteria established in Internal Control—Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the TreadwayCommission. Based on our assessment using those criteria, we concluded that, as of December 31, 2017, our internal control over financial reporting waseffective.Changes in Internal Control over Financial ReportingIn our annual report on Form 10-K for the year ended December 31, 2015, management concluded that internal controls over financial reporting were noteffective because of a material weakness in our internal control over financial reporting related to the review of certain assumptions as part of our annualgoodwill impairment assessment. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such thatthere is a reasonable possibility that a material misstatement of the Corporation's annual or interim financial statements will not be prevented or detected on atimely basis.Management implemented its plan to remediate the material weakness described above, which consisted of the following elements:•Enhanced existing control procedures related to the review of the assumptions, data inputs, and calculations,•Implemented additional reviews by qualified personnel and improved the preparation and retention of additional supporting documentation, toenhance the design and documentation of management review controls in order to increase the precision at which management review controlsoperate,70 •Tested and evaluated the design and operating effectiveness of the control procedures,•Assessed the effectiveness of the remediation plan.As of March 31, 2017, management had determined that the material weakness identified has been remediated.Other than the material weakness remediated above, there have been no changes in our internal control over financial reporting during the period coveredthat have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Our process for evaluating controlsand procedures is continuous and encompasses constant improvement of the design and effectiveness of established controls and procedures and theremediation of any deficiencies, which may be identified during this process.Item 9B - Other InformationNonePART IIIItem 10 - Directors, Executive Officers and Corporate GovernanceThe information required by this Item is incorporated herein by reference to the information in our Definitive Proxy Statement to be filed with the SEC within120 days after the end of the Company’s fiscal year ended December 31, 2017 in connection with our 2018 Annual Meeting of Stockholders (the “2018Proxy Statement”) or an amendment to this Report filed within the same time period (the “Amendment”), in either case, set forth under the captions “Electionof Directors,” “Management Information,” “Corporate Governance” and “Section 16(a) Beneficial Ownership Reporting Compliance.”We have adopted a code of business conduct and ethics that applies to our Chief Executive Officer and Chief Financial Officer.
