PART I
 
ITEM 1 – BUSINESS
 
Overview
 
As used in the Annual Report on Form 10-K, the terms “we,” “us,” “our,” "Zoom” and the “Company” mean Zoom Telephonics, Inc. and its wholly owned subsidiary MTRLC LLC.
 
Zoom Telephonics designs, produces, markets, sells, and supports Internet access and other communications-related products including cable modems and gateways, mobile broadband modems, Asymmetrical Digital Subscriber Line (“ADSL” or commonly “DSL”) modems, and dial-up modems. Our primary objective is to build upon our position as a leading producer of Internet access devices sold through sales channels that include many of the largest United States (“USA” or “US”) high-volume electronics retailers, and to take advantage of a number of trends in communications including higher data rates, increasing use of wireless technology for transmission of data, and increasing use of smartphones, tablets, and streaming media.
 
Cable modem products, including both cable modems and cable gateways, were Zoom’s highest revenue product category in both 2016 and 2015. Cable modems provide a high-bandwidth connection to the Internet through a cable that connects to the cable service provider’s managed broadband network. When a cable modem also includes a built-in WiFi router, it is called a cable gateway. We began shipping cable modems in 2000. Our primary means of distribution to end-users in the US, our primary market, is through national retailers and distributors. We continue to sell cable modem products under the Zoom brand, and beginning in 2016 we started offering cable modems and gateways under the Motorola brand. In response to demand for faster connection speeds and increased functionality including improved WiFi performance, we have invested and continue to invest resources to advance our cable modem product line.
  
Our mobile broadband products provide a high-bandwidth connection to the Internet through access to a mobile service provider’s mobile broadband network. Zoom has sold mobile broadband modems and routers in the past, and Zoom plans to ship a new line of mobile broadband modems, routers, and sensors in 2017.
 
Our DSL modems provide a high-bandwidth connection to the Internet through a telephone line that typically connects to compatible DSL equipment that is typically managed by the DSL service provider. In past years Zoom has shipped a broad line of DSL modems. Zoom’s primary DSL product today includes a DSL modem and a 802.11n (“wireless-N”) router.
 
Our dial-up modems connect personal computers and other devices to the local telephone line for transmission of data, fax, voice, and other information. Our dial-up modems enable personal computers and other devices to connect to other computers and networks, including the Internet, at top data speeds up to 56,000 bits per second. Zoom’s sales of dial-up modems, our largest source of revenues from the mid-eighties through 2010, are expected to continue their decline due to the ongoing adoption of broadband access.
 
In August 2016 we extended our Motorola license to a worldwide license that includes cable modems and gateways, WiFi routers, WiFi range extenders, powerline communication devices, and related products. We plan to introduce a line of Motorola brand WiFi routers, range extenders, and powerline communication products in 2017.

We are incorporated in Delaware under the name Zoom Telephonics, Inc.  Zoom Telephonics, Inc. was originally incorporated in New York in 1977 and changed its state of incorporation to Delaware in 1993. MTRLC LLC, a wholly owned subsidiary of Zoom Telephonics, Inc., is a limited liability company organized in Delaware that focuses on the sale of our Motorola brand products. Our principal executive offices are located at 99 High Street, Boston, MA 02110, and our telephone number is (617) 423-1072. Our Web site is at www.zoomtel.com. Information contained on our web site does not constitute part of this prospectus. Our common stock is traded on the Over-The-Counter market (“OTCQB”) under the symbol ZMTP.
 
 Available Information
 
Our Internet website address is www.zoomtel.com. Through our website we make available, free of charge, our annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and any amendments to those reports, as soon as reasonably practicable after we electronically file such material with, or furnish it to, the SEC. These SEC reports can be accessed through the investor relations section of our website and at the SEC’s web site.
 
Products
 
General
 
The vast majority of our products involve communication of data through the Internet. Our cable modems connect to the cable-TV cable and our DSL modems connect to the local telephone line to provide a high-speed link to the Internet. Our mobile broadband modems and our coming mobile broadband routers and sensors connect to the Internet through a mobile service provider’s mobile broadband cellular network.  Our dial-up modems link computers, point-of-purchase terminals, or other devices to each other or the Internet through the traditional telephone network. Our router products may communicate with a broadband modem for access to the Internet, and they may also be used for local area network communications.  Our planned sensor products will connect sensors to users’ smartphones and Web browsers via a mobile broadband connection to the Internet.
 
Cable Modems
 
We have obtained CableLabs® certification for our currently marketed cable modems, and these cable modems have also received a number of cable service provider certifications. The lengthy, expensive, and technically challenging certification process has been and continues to be a significant barrier to entry.
 
Zoom sells cable modems to end-users through retailers and cable service providers. While sales through the retail channel have been significant, they have been handicapped by the fact that all cable service providers offer cable modems directly with their service. Our view is that cable service providers are required to separately state the non-subsidized rental fees of carrier-provided modems and to eliminate this fee if the consumer chooses to provide the modem, but that view has been challenged by Charter. Charter has not complied with these requirements, thereby hindering consumer choice and the retail modem market.  Nevertheless, Zoom has significant cable modem sales through retailers, often to end-users who want to eliminate a monthly cable modem rental charge from their cable service provider.
 
During 2015 Zoom’s cable modem revenues were primarily from four types of Zoom brand cable modems, all supporting Data Over Cable Service Interface Specification (“DOCSIS”) 3.0 with either 16 or 8 downstream channels and 4 upstream channels (“16x4” or “8x4”). One product was an 8x4 cable modem bridge, one was a 16x4 cable modem bridge, one was an 8x4 cable modem gateway that included an N300 wireless-N router, and one was an 8x4 cable modem gateway that included an 802.11ac (“wireless-AC”) AC1900 router. Zoom continues to sell Zoom brand cable modems, but Zoom’s primary cable modem sales in 2016 were of Motorola brand cable modem products.
 
In May 2015 Zoom entered into an agreement to license certain Motorola trademarks from Motorola Trademark Holdings, LLC (“Motorola”) for cable modem products. From January 1, 2016 through December 31, 2020 we are authorized to manufacture, sell and market consumer cable modem products through certain authorized sales channels using the Motorola trademarks. The agreement includes numerous requirements intended to assure the quality and reputation of Motorola brand products. In January 2016 Zoom, through its MTRLC LLC subsidiary which was formed on October 6, 2015, began shipping cable modems under the Motorola brand. Zoom will also continue to ship Zoom brand cable modems, but these will be distinctly different from our Motorola brand cable modem products. On August 8, 2016, Zoom entered into an amendment to the license agreement with Motorola. The amendment expands Zoom’s exclusive license to use the Motorola trademark to a wide range of authorized channels worldwide, and expands the license from cable modems and gateways to also include consumer routers, WiFi range extenders, home powerline network adapters, and related products.

MTRLC LLC currently ships six Motorola brand cable modem products. The least expensive product in this line is an 8x4 DOCSIS 3.0 cable modem, and the most expensive is a cable gateway that includes a 16x4 DOCSIS 3.0 cable modem and an AC1900 WiFi router with Power Boost. Zoom is continuing to develop new cable modems, including a DOCSIS 3.1 cable modem.
 
DSL Modems
 
Our DSL modems incorporate the ADSL standards that are currently most popular worldwide, including ADSL2/2+, G.dmt, G.Lite, and ANSI T1.413 issue 2. Zoom currently sells one type of ADSL modem, which has an integrated wireless-N 4-port router using Broadcom Integrated Circuit (“IC”) technology.
 
Mobile Broadband Modems and Routers
 
During the second half of 2009 Zoom began shipping its first mobile broadband or “cellular” products, mobile broadband modems and wireless-N routers. In 2017 Zoom plans to introduce a new line of mobile broadband modems, with different models designed to work with AT&T, Verizon, and other mobile broadband carriers worldwide. Zoom also plans to introduce a cellular gateway that includes a modem capable of speeds up to 100 Mbps and an AC1900 router.
 
Dial-Up Modems
 
We have a broad line of dial-up modems with top data speeds up to 56,000 bps, available in external and internal models. Many of our external modems are designed to work with almost any terminal or computer, or operating system including Windows, Apple, Linux, and others. Personal Computer (“PC”) oriented internal modems are designed primarily for installation in the Peripheral Component Interconnect (“PCI”) slot, PCI-E slot, or PC card slot of IBM PC-compatibles. Embedded internal modems are designed to be embedded in PCs dedicated for a specific application, such as point-of-purchase terminals, kiosks, and set-top boxes. We sell and market dial-up modems under the Zoom® and Hayes® brands, as well as selling unbranded or private labeled modems for some specific high-volume accounts.
 
Mobile Broadband Sensors
 
 In 2017 Zoom plans to introduce a line of sensor products that communicate sensor data via a built-in cellular modem through the Internet to a smartphone or browser-enabled device. This cellular approach makes these sensors easier to install than a sensor that requires a router and a broadband connection. This approach can be teamed up with a very low cost data plan, since the amount of data being transmitted is low. The simplest product will only communicate temperature, and Zoom plans to have a range of products including a multi-sensor that senses temperature, humidity, earthquake and other acceleration, motion, pressure, light, and sound. Zoom believes that there is significant potential for cellular sensor products, but that there are significant risks including risk relating to delays in finishing these products and risks from competitors.
 
 Products for Markets outside North America
 
Products for countries outside the US often differ from a similar product for the US due to different regulatory and certification requirements, country-specific phone jacks and AC power adapters, and language-related specifics. As a result, the introduction of new products into markets outside North America can be costly and time-consuming. In 1993 we introduced our first dial-up modem approved for selected Western European countries. Since then we have continued to expand our product offerings into markets outside North America. We have received regulatory certifications for, and are currently selling our products in a number of countries, including the US, the United Kingdom (“UK”), Spain, Canada, Vietnam, and some Latin American countries. We intend to continue to expand and enhance our product line for our existing markets and to seek certifications for the sale of new products outside the US. Most importantly, we hope to sell Motorola brand WiFi products in China, Latin America, Europe, and other regions outside the USA. The vast majority of our sales were in North America in 2015 and in 2016, and we expect North America to continue to account for most of our sales. However, we expect significant growth outside North America due to our worldwide Motorola license for WiFi and powerline products.
 
Sales Channels
 
General
 
We sell our products primarily through high-volume retailers and distributors, Internet service providers, service providers, value-added resellers, PC system integrators, and Original Equipment Manufacturers ("OEMs"). We support our major accounts in their efforts to discern strategic directions in the market, to maintain appropriate inventory levels, and to offer a balanced selection of attractive products.

Relatively few customers have accounted for a substantial portion of the Company’s revenues.  In 2016 three customers accounted for 82% of our total net sales, with our largest customer accounting for 29% of our net sales. At December 31, 2016, three customers accounted for 86% of our gross accounts receivable, with our largest customer representing 56% of our gross accounts receivable. In 2015 three customers accounted for 77% of the Company’s total net sales with our largest customer accounting for 46% of our net sales. At December 31, 2015, three customers accounted for 93% of our gross accounts receivable, with our largest customer representing 67% of our gross accounts receivable.
 
Distributors and Retailers outside North America
 
In markets outside North America we sell and ship our products primarily to distributors. We believe that sales growth outside North America will continue to require substantial additional investments of resources for product design and testing, regulatory certifications, native-language instruction manuals and software, packaging, sales support, and technical support. We have made this investment in the past for many countries, and we expect to make this investment for some countries and products in the future.   However, we anticipate that the vast majority of our future sales will come from the US, largely because the US has an unusually robust retail cable modem market.
 
We have announced a master distributor agreement with T&W, a Chinese manufacturer and our primary supplier, whereby T&W will be the master distributor for some of our Motorola brand product categories in China. We hope to have similar agreements for some other countries, but there is no guarantee that we will have such agreements. We have a distributor for Latin America, and we hope that distributor will sell some of our Motorola brand WiFi products. We hope to add other distributors for some countries outside North America. We also expect to sell some Motorola brand WiFi products through Amazon UK and other Amazon sites in Europe.
 
North American High-volume Retailers and Distributors
 
In North America we reach the retail market primarily through high-volume retailers. Our North American retailers include Best Buy, Micro Center, Target, Wal-Mart, and others including Amazon and other Web-focused retailers.
 
We sell significant quantities of our products through distributors, who often sell to corporate accounts, retailers, service providers, value-added resellers, equipment manufacturers, and other customers. Our North American distributors include D&H Distributing, Ingram Micro, and Tech Data.
 
Internet and Telephone Service Providers
 
In past years our sales have included DSL modems sold to DSL service providers in the US and in some other countries. We plan to continue selling and supporting these customers. In addition, we will continue to offer some of our cable modem and mobile broadband products to service providers.
 
System Integrators and Original Equipment Manufacturers
 
Our system integrator and OEM customers sell our products under their own name or incorporate our products as a component of their systems. We seek to be responsive to the needs of these customers by providing on-time delivery of high-quality, reliable, cost-effective products with strong engineering and sales support. We believe that some of these customers also appreciate the improvement in their products' image due to use of a Zoom or Hayes brand modem.
 
Sales, Marketing & Support
 
Our sales, marketing, and support are primarily managed from our headquarters in Boston, Massachusetts. In North America we sell our Zoom, Motorola, Hayes, and private-label dial-up modem products through Zoom's sales force and through commissioned independent sales representatives managed and supported by our own staff. Most service providers are serviced by Zoom's sales force. Worldwide technical support is primarily handled from our Boston headquarters.
 
We believe that Motorola, Zoom, Hayes, and Global Village are widely recognized brand names. We build upon our brand equity in a variety of ways, including Amazon advertising, Google Adwords advertising, Facebook advertising, retailer cooperative advertising, product packaging, trade shows, and public relations.
 
 
 
7
 
 
We attempt to develop quality products that are user-friendly and that require minimal support. We typically support our claims of quality with product warranties of one to two years, depending upon the product. To address the needs of end-users and resellers who require assistance, we have our own staff of technical support specialists.  They provide telephone support five days per week in English and Spanish. Our technical support specialists also maintain a significant Internet support facility that includes email, firmware and software downloads, and the SmartFacts™ Q&A search engine.
 
Research & Development
 
Our research and development efforts are focused on developing new products, enhancing the capabilities of existing products, and reducing production costs. We have developed close collaborative relationships with certain of our Original Design Manufacturer (“ODM”) suppliers and component suppliers. We work with these partners and other sources to identify and respond to emerging technologies and market trends by developing products that address these trends. In addition, we purchase modems and other chipsets that incorporate sophisticated technology from third parties, thereby eliminating the need for us to develop this technology in-house. We do however develop products in-house, including some modems and our Connected Home product line.
 
The Company’s costs on research and development were $1.5 million for 2016 and $1.3 million for 2015. As of December 31, 2016 we had 10 employees engaged primarily in research and development. Our research and development team performs electronics hardware design and layout, mechanical design, prototype construction and testing, component specification, firmware and software development, product testing, foreign and domestic regulatory certification efforts, end-user and internal documentation, and third-party software selection and testing.
 
Manufacturing & Suppliers
 
Our products are currently designed for high-volume automated assembly to help assure reduced costs, rapid market entry, short lead times, and reliability. High-volume assembly typically occurs in China or Taiwan. Our contract manufacturers and original design manufacturers typically obtain some or all of the material required to assemble the products based upon a Zoom Telephonics Approved Vendor List and Parts List. Our manufacturers typically insert parts onto the printed circuit board, with most parts automatically inserted by machine, solder the circuit board, and test the completed assemblies. The contract manufacturer sometimes performs final packaging. For the US and many other markets, packaging is often performed at our facilities in North America, allowing us to tailor the packaging and its contents for our customers immediately before shipping. This facility also performs warehousing, shipping, quality control, finishing and some software updates from time to time. We also perform circuit design, circuit board layout, and strategic component sourcing at our Boston headquarters. Wherever the product is built, our quality systems are used to help assure that the product meets our specifications.
 
Our North American facility is currently located in Tijuana, Mexico. From time to time we experience certain challenges associated with the Tijuana facility, specifically relating to bringing products across the border between the US and Mexico.   We believe that this facility assists us in cost-effectively providing rapid response to the needs of our US customers.
 
Historically we have used one primary manufacturer for a given design. We sometimes maintain back-up production tooling at a second manufacturer for our highest-volume products. Our manufacturers are normally adequate to meet reasonable and properly planned production needs; but a fire, natural calamity, strike, financial problem, or other significant event at an assembler's facility could adversely affect our shipments and revenues. In 2016, one supplier provided 92% of our purchased inventory. The loss of a key supplier, or a material adverse change in a key supplier’s business or in our relationship with a key supplier, could materially and adversely harm our business.
 
Our products include a large number of parts, most of which are available from multiple sources with varying lead times. However, most of our products include a sole-sourced chipset as the most critical component of the product. The vast majority of our cable and DSL modem chipsets come exclusively from Broadcom. Our dial-up modem chipsets come exclusively from Conexant. Serious problems at Broadcom or Conexant, including long chipset lead-times, would significantly reduce Zoom’s shipments.
 
We have experienced delays in receiving shipments of modem chipsets in the past, and we may experience such delays in the future. Moreover, we cannot assure that a chipset supplier will, in the future, sell chipsets to us in quantities sufficient to meet our needs or that we will purchase the specified dollar amount of products necessary to receive concessions and incentives from a chipset supplier. An interruption in a chipset supplier's ability to deliver chipsets, a failure of our suppliers to produce chipset enhancements or new chipsets on a timely basis and at competitive prices, a material increase in the price of the chipsets, our failure to purchase a specified dollar amount of products or any other adverse change in our relationship with modem component suppliers could have a material adverse effect on our results of operations.
 
 
 
8
 
 
We are also subject to price fluctuations in our cost of goods. Our costs may increase if component shortages develop, lead-times stretch out, fuel costs rise, or significant delays develop due to labor-related issues.
 
We are also subject to the Restriction of Hazardous Substances Directive (“RoHS”) and Consumer Electronics Control (“CEC”) rules discussed above, which affect component sourcing, product manufacturing, sales, and marketing.
 
Competition
 
The Internet access and networking industries are intensely competitive and characterized by aggressive pricing practices, continually changing customer demand patterns, rapid technological advances, and emerging industry standards. These characteristics result in frequent introductions of new products with added capabilities and features, and continuous improvements in the relative functionality and price of modems and other communications products. Our operating results and our ability to compete could be adversely affected if we are unable to:
 
successfully and accurately anticipate customer demand;
 
manage our product transitions, inventory levels, and manufacturing processes efficiently;
 
distribute or introduce our products quickly in response to customer demand and technological advances;
 
differentiate our products from those of our competitors; or
 
otherwise compete successfully in the markets for our products.
 
Some of our primary competitors by product group include the following:
 
Cable modem competitors: Arris, Belkin/Linksys, D-Link, Hon Hai Network Systems (formerly Ambit Microsystems), Netgear, Sagemcom, SMC Networks, Technicolor, TP-Link and Ubee Interactive.
 
Dial-up modem competitors: Best Data, Hiro, Lite-On, Multitech, and US Robotics.
 
DSL modem competitors: Arris, Actiontec, Asus, Aztech,, Belkin / Linksys, D-Link, Huawei, Netgear, Sagemcom (formerly Sagem), Siemens (formerly Efficient Networks), Technicolor, TP-Link, Westell, Xavi, and ZyXEL Communications.
 
Mobile broadband competitors: Cradlepoint, D-Link, Huawei, Inseego, Multitech, Netcomm Wireless, Netgear, Nimbelink, Option, Sierra Wireless, and ZTE.
 
Networking competitors: Amped, Apple, Asus, Belkin/Linksys,, D-Link, Eero, Google, Netgear, Securifi, Tenda, TP-Link, Trendnet, and Ubiquiti.
           
Many of our competitors and potential competitors have more extensive financial, engineering, product development, manufacturing, and marketing resources than we do.
 
The principal competitive factors in our industry include the following:
 
 
● product performance, features, reliability and quality of service;
 
 
● price;
 
 
 ● brand image;
 
 
● product availability and lead times;
 
 
● size and stability of operations;
 
 
● breadth of product line;
 
 
 
9
 
 
 
● sales and distribution capability, including retailer and distributor relationships;
 
 
● technical support and service;
 
 
● product documentation and product warranties;
 
 
● relationships with providers of broadband access services; and
 
 
● certifications evidencing compliance with various requirements.
 
We believe we are able to provide a competitive mix of the above factors for our products, particularly when they are sold through retailers, computer product distributors, small to medium sized Internet service providers, and system integrators. We have been less successful in selling directly to large telephone companies and other large providers of broadband access services.
  
Successfully penetrating the broadband modem market presents a number of challenges, including:
 
  ● the current limited retail market for broadband modems;
 
  ● the relatively small number of cable, telecommunications and Internet service providers that make up the majority of the market for broadband modems in the USA, our largest market;
 
  ● the significant bargaining power and market dominance of these large service providers;
 
  ● the time-consuming, expensive and uncertain certification processes of the various cable and DSL service providers; and
 
  ● the strong relationships with service providers enjoyed by some incumbent equipment providers, including ARRIS for cable modems and Huawei for DSL and mobile broadband modems.
 
Intellectual Property Rights
 
We rely primarily on a combination of copyrights, trademarks, trade secrets and patents to protect our proprietary rights. We have trademarks and copyrights for our firmware (software on a chip), printed circuit board artwork, instructions, packaging, and literature. We also have five active patents that expire between years 2020 and 2031. We cannot assure that any patent application will be granted or that any patent obtained will provide protection or be of commercial benefit to us, or that the validity of a patent will not be challenged. Moreover, we cannot assure that our means of protecting our proprietary rights will be adequate or that our competitors will not independently develop comparable or superior technologies.
 
We license certain technologies used in our products, typically rights to bundled software, on a non-exclusive basis. In addition we purchase chipsets that incorporate sophisticated technology. We have received, and may receive in the future, infringement claims from third parties relating to our products and technologies. We investigate the validity of these claims and, if we believe the claims have merit, we respond through licensing or other appropriate actions. Certain of these past claims have related to technology included in modem chipsets. We forwarded these claims to the appropriate vendor. If we or our component manufacturers were unable to license necessary technology on a cost-effective basis, we could be prohibited from marketing products containing that technology, incur substantial costs in redesigning products incorporating that technology, or incur substantial costs defending any legal action taken against it. Where possible we attempt to receive patent indemnification from chipset suppliers and other appropriate suppliers, but the extent of this coverage varies and enforcement of this indemnification may be difficult and costly.
 
In May 2015 we entered into an agreement to license certain Motorola® brand trademarks for consumer cable modem products in the US and Canada through certain authorized sales channels using such trademarks beginning January 1, 2016 through December 31, 2020. On August 8, 2016, we entered into an amendment to the license agreement with Motorola. The amendment expands our exclusive license to use the Motorola trademark to a wide range of authorized channels worldwide, and expands the license from cable modems and gateways to also include consumer routers, WiFi range extenders, home powerline network adapters and access ports.

 ITEM 1A. – RISK FACTORS
 
Risks Related to Our Business
 
Our recent license agreement with Motorola has risks, including risks associated with our ability to successfully generate Motorola sales that are large enough to make our Motorola business profitable after we pay the minimum annual royalty payments required by the license agreement. Our failure to successfully increase Motorola sales would have an adverse effect on our liquidity and financial results.
 
In May 2015 Zoom entered into an agreement to license the Motorola brand trademark for use with cable modem products in North America for five years starting with shipments January 2016. In August 2016 that agreement was amended to include WiFi routers, range extenders, and other products worldwide, and to increase the minimum royalty payments. In connection with this opportunity, Zoom has an aggressive plan to continue to introduce new Motorola brand products. Our product development plan has and will continue to increase our costs and may result in cost overruns and delays. If our sales of Motorola brand products do not meet our forecasts, this may result in excess inventory and a shortage of cash. In addition, the license agreement includes significant minimum quarterly royalty payments due by Zoom. If we are unable to sell a sufficient number of Motorola brand products to offset these minimum royalty payments, our net income and cash position will be reduced and we may experience losses.
 
We may require additional funding, which may be difficult to obtain on favorable terms, if at all.
 
Over the next twelve months we may require additional funding if, for instance, we buy inventory and develop products in anticipation of significant Motorola sales, if our sales are lower than forecast, or if we continue to experience losses. On September 1, 2016, we signed an amendment to our financing agreement to increase our line of credit to $3.0 million assuming our receivables support this amount; and this line is subject to covenants that must be met and may be terminated by the lender at any time upon sixty days prior notice. It is not certain whether all or part of this line of credit will be available to us in the future; and other sources of financing may not be available to us on a timely basis if at all, or on terms acceptable to us. If we fail to obtain acceptable additional financing when needed, we may not have sufficient resources to fund our normal operations; and this would have a material adverse effect on our business.
 
We may experience costs and senior management distractions due to patent-related matters.
 
Many of our products incorporate patented technology. We attempt to license appropriate patents either directly or through our integrated circuit suppliers. However, we are subject to costs and senior management distractions due to patent-related litigation.
 
On May 17, 2016, Magnacross LLC ("Magnacross") filed a complaint in the U.S. District Court for the Eastern District of Texas (U.S.D.C., E.D.Tex.) against the Company alleging infringement of U.S. Patent No. 6,917,304 (“the ’304 patent”) entitled “Wireless Multiplex Data Transmission System.” Magnacross alleged that the Company’s wireless routers, including its Model 5363, 5360, and 5354 (N300, N600, and AC1900) Routers, infringe the '304 patent. In its complaint, Magnacross sought injunctive relief and unspecified compensatory damages. The case was resolved on February 1, 2017 with the entry by the judge of an Order of Dismissal with Prejudice.
 
Patent litigation matters are complex and time consuming and expose Zoom to potentially material obligations. It is impossible to assess the potential cost and senior management distraction associated with patent litigation matters that are currently outstanding or may occur in the future.
 
Our reliance on a small number of customers for a large portion of our revenues could materially harm our business and prospects.
 
Relatively few customers account for a substantial portion of the Company’s revenues.  In 2016 three customers accounted for 82% of our total net sales, with our largest customer accounting for 29% of our net sales. At December 31, 2016, three customers accounted for 86% of our gross accounts receivable, with our largest customer representing 56% of our gross accounts receivable. In 2015 three customers accounted for 77% of the Company’s total net sales with our largest customer accounting for 46% of our net sales. At December 31, 2015, three customers accounted for 93% of our gross accounts receivable, with our largest customer representing 67% of our gross accounts receivable.
 
 
 
12
 
 
Our customers generally do not enter into long-term agreements obligating them to purchase our products. Because of our significant customer concentration, our net sales and operating income could fluctuate significantly due to changes in political or economic conditions or the loss of, reduction of business with, or less favorable terms for any of our significant customers. A reduction or delay in orders from any of our significant customers, or a delay or default in payment by any significant customer could materially harm our business, results of operation and liquidity.
 
Our business may be harmed due to Charter Communications Inc.’s (“Charter”) having acquired Time Warner Cable and Bright House Networks, to the extent that Charter extends its policy of not offering customers a savings when customers supply their own cable modem.
 
In applying for FCC approval of its proposed acquisition of Time Warner Cable and Bright House Networks, Charter stated that it would extend its practice of charging a single price for cable modem leasing and Internet service to some customers in the newly-acquired cable systems. Zoom’s position has been and remains that they should separately state a non-subsidized price for the cable modem, offering customers a saving if they use their own modem instead. In its public filings, Charter stated that it had about 4.8 million residential customers. Charter has also stated that if the proposed transactions were consummated, Charter would acquire about 10.8 million residential customers from Time Warner Cable and about 2.5 million residential and business customers from Bright House Networks. Zoom filed an action at the FCC which asked that the FCC deny Charter’s application for the proposed acquisitions or, if the acquisitions were approved, that they be conditioned on a requirement that Charter separately state the price of the Charter-supplied cable modem, and that price not be subsidized. Charter did successfully acquire Time Warner Cable and Bright House, and there was no associated FCC requirement that Charter separately state the price of the Charter-supplied cable modem, and that price not be subsidized. We believe that Charter has extended its bundled, subsidized approach to some but not all Time Warner Cable and Bright House customers, but that policy could change. Zoom is continuing its efforts to obtain relief from the FCC, but these efforts may not be successful. Charter’s policy eliminates one of the major incentives for purchasing a cable modem, and thereby threatens cable modem sales by retailers and threatens Zoom as a supplier to these retailers. We believe our sales of cable modems will be reduced in markets where Charter extends its policy of bundling its offering of a subsidized cable modem with its Internet service.
 
Product liability claims related to future sensor products could harm our competitive position, results of operations and financial condition.
 
We plan to introduce products that may be used to monitor for threats such as fire, flooding, break-ins, medical emergencies, and other threats; to allow remote control of our Connected Home products and attached electrical devices; and to cause actions including alerts and sirens in certain situations.  If our products fail to provide accurate and timely information or to operate as designed, our customers could assert claims against us for product liability. Litigation with respect to product liability claims, regardless of any outcome, could result in substantial cost to us, divert management’s attention from operations and decrease market acceptance of our products. While we intend to carry product liability insurance, we cannot give any assurance that our current or future insurance coverage will be sufficient to cover all possible liabilities. Further, we can give no assurance that adequate insurance will be available to us or that such insurance may be maintained at a reasonable cost to us. A successful claim brought against us, or any claim or product recall that results in negative publicity about us, could harm our competitive position, results of operations and financial condition.
 
The market for Internet access products and services has many competing technologies, and the demand for certain of our products and services is declining.
 
If we are unable to grow demand for our broadband and dial-up modems or other products, we may be unable to sustain or grow our business. The market for high-speed communications products and services has a number of competing technologies. For instance, Internet access can be achieved by using a standard telephone line with an appropriate modem and dial-up or DSL service; using a cable TV line with a cable modem and cable modem service; or using a mobile broadband modem and mobile broadband service. We currently sell products that include all these technologies. The introduction of new products by competitors, market acceptance of competing products based on new or alternative technologies, or the emergence of new industry standards have in the past rendered and could continue to render our products less competitive or even obsolete.
 
 
 
13
 
 
Our reliance on sole suppliers or limited sources of supply could materially harm our business.
 
We obtain certain key parts, components, and equipment from sole or limited sources of supply. In 2016, the Company had one supplier that provided 92% of the Company's purchased inventory. In 2015 the Company had two suppliers that provided 85% of the Company's purchased inventory. Also, as examples, the vast majority of our broadband modems use Broadcom chipsets and the vast majority of our dial-up modems use Conexant chipsets.  The loss of the services of any of our significant suppliers or a material change in their business or their relationship with us could harm our business and operating results. In the past we have experienced long lead-times and significant delays in receiving shipments of modem chipsets from our sole source suppliers. We may experience similar delays in the future. In addition, some products may have other components that are available from only one source. If we are unable to obtain a sufficient supply of components from our current sources, we would experience difficulties in obtaining alternative sources or in altering product designs to use alternative components. Resulting delays or reductions in product shipments could damage relationships with our customers, and our customers could decide to purchase products from our competitors. Inability to meet our customers’ demand or a decision by one or more of our customers to purchase products from our competitors could harm our operating results.
 
Fluctuations in the foreign currency exchange rates in relation to the US dollar could have a material adverse effect on our operating results.
 
Changes in currency exchange rates that increase the relative value of the US dollar may make it more difficult for us to compete with foreign manufacturers on price, may reduce our foreign currency denominated sales when expressed in dollars, or may otherwise have a material adverse effect on our sales and operating results. A significant increase in our foreign currency denominated sales would increase our risk associated with foreign currency fluctuations. A weakness in the US dollar relative to the Mexican peso and various Asian currencies, especially the Chinese renminbi (“RMB”), could increase our product costs. Fluctuations in the currency exchange rates have, and may continue to, adversely affect our operating results.
 
Capacity constraints in our Mexican operations could reduce our sales and revenues and hurt customer relationships.
 
We rely on our Mexican operations to finish and ship most of the products we sell. Since moving our operations to our Mexican facility we have experienced and may continue to experience constraints on our capacity as we address challenges related to operating our new facility, such as hiring and training workers, creating the facility’s infrastructure, developing new supplier relationships, complying with customs and border regulations, and resolving shipping and logistical issues. Our sales and revenues may be reduced and our customer relationships may be impaired if we continue to experience constraints on our capacity. We are working to minimize capacity constraints in a cost-effective manner, but there can be no assurance that we will be able to adequately minimize capacity constraints.
 
Our reliance on a business processing outsourcing partner to conduct our operations in Mexico could materially harm our business and prospects.
 
In connection with our North American manufacturing operations in Mexico, we rely on a business processing outsourcing partner to hire, subject to our oversight, the team for our Mexican operations, provide the selected facility described above, and coordinate many of the ongoing logistics relating to our operations in Mexico. Our outsourcing partner’s related functions include acquiring the necessary Mexican permits, providing the appropriate Mexican operating entity, assisting in customs clearances, and providing other general assistance and administrative services in connection with the ongoing operation of the Mexican facility. Our outsourcing partner’s performance of these obligations efficiently and effectively is critical to the success of our operations in Mexico. Failure of our outsourcing partner to perform its obligations efficiently and effectively could result in delays, unanticipated costs or interruptions in production, delays in deliveries to our customers or other harm to our business, results of operation, and liquidity. Moreover, if our outsourcing arrangement is not successful, we cannot assure our ability to find an alternative production facility or outsourcing partner to assist in our operations in Mexico or our ability to operate successfully in Mexico without outsourcing or similar assistance.

We believe that our future success will depend in large part on our ability to more successfully penetrate the broadband modem markets, which have been challenging markets, with significant barriers to entry.
 
We believe that our future success depends in large part on our ability to penetrate the broadband modem markets including cable and mobile broadband. These markets have significant barriers to entry. Although some cable, and mobile broadband modems are sold at retail, the high volume purchasers of these modems are concentrated in a relatively few large cable, telephone, and mobile broadband service providers which offer broadband modem services to their customers. These customers, particularly cable and mobile broadband services providers, also have extensive and varied certification processes for modems to be approved for use on their network. These certifications are expensive and time consuming, and they continue to evolve. Successfully penetrating the broadband modem market therefore presents a number of challenges including: the current limited retail market for broadband modems; the relatively small number of cable, telecommunications and Internet service provider customers that make up the bulk of the market for broadband modems in certain countries, including the US; the significant bargaining power of these large volume purchasers; the time consuming, expensive, uncertain and varied certification process of the various cable service providers; the savings if any offered to customers who use their own modem instead of one supplied by the service provider; and the strong relationships with cable service providers enjoyed by incumbent cable equipment providers like ARRIS.
 
If we fail to meet changing customer requirements and emerging industry standards, there would be an adverse impact on our ability to sell our products and services.
 
The market for Internet access products and services is characterized by aggressive pricing practices, continually changing customer demand patterns, rapid technological advances, emerging industry standards and short product life cycles. Some of our product and service developments and enhancements have taken longer than planned and have delayed the availability of our products and services, which adversely affected our sales and profitability in the past. Any significant delays in the future may adversely impact our ability to sell our products and services, and our results of operations and financial condition may be adversely affected. Our future success will depend in large part upon our ability to: identify and respond to emerging technological trends and industry standards in the market; develop and maintain competitive products that meet changing customer demands; enhance our products by adding innovative features that differentiate our products from those of our competitors; bring products to market on a timely basis; introduce products that have competitive prices; manage our product transitions, inventory levels and manufacturing processes efficiently; respond effectively to new technological changes or new product announcements by others; meet changing industry standards; distribute our products quickly in response to customer demand; and compete successfully in the markets for our new products. These factors could also have an adverse effective on our operating results. 
 
Our product cycles tend to be short and we may incur significant non-recoverable expenses or devote significant resources to sales that do not occur when anticipated. Therefore, the resources we devote to product development, sales and marketing may not generate material net sales for us. In addition, short product cycles have resulted in and may in the future result in excess and obsolete inventory, which has had and may in the future have an adverse effect on our results of operations. In an effort to develop innovative products and technology, we have incurred and may in the future incur substantial development, sales, marketing, and inventory costs. If we are unable to recover these costs, our financial condition and operating results could be adversely affected. In addition, if we sell our products at reduced prices in anticipation of cost reductions and we still have higher cost products in inventory, our business would be harmed and our results of operations and financial condition would be adversely affected.
 
Our international operations are subject to a number of risks that could harm our business.
 
Currently our business is significantly dependent on our operations outside the US, particularly the production of substantially all of our products. For the fiscal year ending December 31, 2016 sales outside North America were only 1.1% of our net sales.  However, almost all of our manufacturing operations are now located outside of the US.  The inherent risks of international operations could harm our business, results of operation, and liquidity. For instance, our operations in Mexico are subject to the challenges and risks associated with international operations, including those related to integration of operations across different cultures and languages, and economic, legal, political and regulatory risks. In addition, fluctuations in the currency exchange rates have had, and may continue to have, an adverse effect on our operating results. The types of risks faced in connection with international operations include, among others: regulatory and communications requirements and policy changes; currency exchange rate fluctuations, including changes in value of the Mexican peso relative to the US dollar; cultural differences; reduced control over staff and other difficulties in staffing and managing foreign operations; reduced protection for intellectual property rights in some countries; political and economic changes and disruptions; governmental currency controls; shipping costs; strikes and work slowdowns at ports or other locations in the supply path; and import, export, and tariff regulations.  Almost all of our products are built in mainland China or Taiwan, so these products are subject to numerous risks including currency risk and economic, legal, political and regulatory risks.  Additionally, President Donald Trump has expressed antipathy towards certain existing international trade agreements, including the North American Free Trade Agreement (NAFTA), and has made comments suggesting that he supports significantly increasing tariffs on goods imported into the United States from countries such as Mexico and China. As of the date of this Form 10-K, it remains unclear what actions, if any, will occur with respect to NAFTA, other international trade agreements, and tariffs on goods imported into the United States. If the United States were to withdraw from or materially modify NAFTA or other international trade agreements to which it is a party, or if tariffs were raised on the China-sourced products that we buy, our costs for such products could increase significantly, which in turn could have a material adverse effect on our business, financial condition and results of operations.
 
 
 
15
 
 
We may be subject to product returns resulting from defects or from overstocking of our products.  Product returns could result in the failure to attain market acceptance of our products, which would harm our business.
 
If our products contain undetected defects, errors, or failures, we could face delays in the development of our products, numerous product returns, and other losses to us or to our customers or end users. Any of these occurrences could also result in the loss of or delay in market acceptance of our products, either of which would reduce our sales and harm our business. We are also exposed to the risk of product returns from our customers as a result of contractual stock rotation privileges and our practice of assisting some of our customers in balancing their inventories. Overstocking has in the past led and may in the future lead to higher than normal returns.
 
If we fail to effectively manage our inventory levels, there could be a material and adverse effect on our liquidity and our business.
 
Due to rapid technological change and changing markets we are required to manage our inventory levels carefully to both meet customer expectations regarding delivery times and to limit our excess inventory exposure. In the event we fail to effectively manage our inventory our liquidity may be adversely affected and we may face increased risk of inventory obsolescence, a decline in market value of the inventory, or losses from theft, fire, or other casualty.
 
We may be unable to produce sufficient quantities of our products because we depend on third party manufacturers. If these third party manufacturers fail to produce quality products in a timely manner, our ability to fulfill our customer orders would be adversely impacted.
 
We use contract manufacturers and original design manufacturers for electronics manufacturing of most of our products. We use these third party manufacturers to help ensure low costs, rapid market entry, and reliability. Any manufacturing disruption could impair our ability to fulfill orders, and failure to fulfill orders would adversely affect our sales. Although we currently use four electronics manufacturers for the bulk of our purchases, in some cases a given product is only provided by one of these companies. The loss of the services of any of our significant third party manufacturers or a material adverse change in the business of or our relationships with any of these manufacturers could harm our business. Since third parties manufacture our products and we expect this to continue in the future, our success will depend, in part, on the ability of third parties to manufacture our products cost effectively and in sufficient quantities to meet our customer demand. 
 
We are subject to the following risks because of our reliance on third party manufacturers: reduced management and control of component purchases; reduced control over delivery schedules, quality assurance, manufacturing yields, and labor practices; lack of adequate capacity during periods of excess demand; limited warranties on products supplied to us; potential increases in prices; interruption of supplies from assemblers as a result of a fire, natural calamity, strike or other significant event; and misappropriation of our intellectual property.
 
Our cable modem sales may be significantly reduced due to long lead-times.
 
Cable modems and other broadband modems represented 94% of Zoom’s net sales during 2016. These products have experienced long lead-times due to certain component production lead-times of up to 20 weeks and due to manufacturer-related delays, and these long lead times may significantly reduce our potential sales.
 
We face significant competition, which could result in decreased demand for our products or services.
 
We may be unable to compete successfully. A number of companies have developed, or are expected to develop, products that compete or will compete with our products. Furthermore, many of our current and potential competitors have significantly greater resources than we do. Intense competition, rapid technological change and evolving industry standards could result in less favorable selling terms to our customers, decrease demand for our products or make our products obsolete.  Our operating results and our ability to compete could be adversely affected if we are unable to: successfully and accurately anticipate customer demand; manage our product transitions, inventory levels, and manufacturing processes efficiently; distribute or introduce our products quickly in response to customer demand and technological advances; differentiate our products from those of our competitors; or otherwise compete successfully in the markets for our products.
 
Environmental regulations may increase our manufacturing costs and harm our business.
 
In the past, environmental regulations have increased our manufacturing costs and caused us to modify products. New state, US, or other regulations may in the future impact our product costs or restrict our ability to ship certain products into certain regions.
 
 
 
16
 
 
Changes in current or future laws or governmental regulations and industry standards that negatively impact our products, services and technologies could harm our business.
 
The jurisdiction of the FCC, extends to the entire US communications industry including our customers and their products and services that incorporate our products. Our products are also required to meet the regulatory requirements of other countries throughout the world where our products and services are sold. Obtaining government certifications is time-consuming and costly. In the past, we have encountered delays in the introduction of our products, such as our cable modems, as a result of government certifications. We may face further delays if we are unable to comply with governmental regulations. Delays caused by the time it takes to comply with regulatory requirements may result in cancellations or postponements of product orders or purchases by our customers, which would harm our business. 
 
In addition to reliability and quality standards, the market acceptance of certain products and services is dependent upon the adoption of industry standards so that products from multiple manufacturers are able to communicate with each other. Standards are continuously being modified and replaced. As standards evolve, we may be required to modify our existing products or develop and support new versions of our products. The failure of our products to comply, or delays in compliance, with various existing and evolving industry standards could delay or interrupt volume production of our products, which could harm our business.
 
Our future success will depend on the continued services of our executive officers and key product development personnel.
 
The loss of any of our executive officers or key product development personnel, the inability to attract or retain qualified personnel in the future, or delays in hiring skilled personnel could harm our business. Competition for skilled personnel is significant. We may be unable to attract and retain all the personnel necessary for the development of our business. In addition, the loss of Frank B. Manning, our president, chief executive officer, and acting chief financial officer or some other member of the senior management team, a key engineer or salesperson, or other key contributors, could harm our relations with our customers, our ability to respond to technological change, and our business.
 
We may have difficulty protecting our intellectual property.
 
Our ability to compete is heavily affected by our ability to protect our intellectual property. We rely primarily on trade secret laws, confidentiality procedures, patents, copyrights, trademarks, and licensing arrangements to protect our intellectual property. The steps we take to protect our technology may be inadequate. Existing trade secret, trademark and copyright laws offer only limited protection. Our patents could be invalidated or circumvented. We have more intellectual property assets in some countries than we do in others. In addition, the laws of some foreign countries in which our products are or may be developed, manufactured or sold may not protect our products or intellectual property rights to the same extent as do the laws of the US. This may make the possibility of piracy of our technology and products more likely. We cannot ensure that the steps that we have taken to protect our intellectual property will be adequate to prevent misappropriation of our technology.
 
We could infringe the intellectual property rights of others.
 
Particular aspects of our technology could be found to infringe on the intellectual property rights or patents of others. Other companies may hold or obtain patents on inventions or may otherwise claim proprietary rights to technology necessary to our business. We cannot predict the extent to which we may be required to seek licenses. We cannot assure that the terms of any licenses we may be required to seek will be reasonable. We are often indemnified by our suppliers relative to certain intellectual property rights; but these indemnifications do not cover all possible suits, and there is no guarantee that a relevant indemnification will be honored by the indemnifying party.
 
Risks Related to the Securities Market and Our Common Stock
 
The market price of our common stock may be volatile and trading volume may be low.
 
The market price of our common stock could fluctuate significantly for many reasons, including, without limitation: as a result of the risk factors listed herein; actual or anticipated fluctuations in our operating results; regulatory changes that could impact our business; and general economic and industry conditions. Shares of our common stock are quoted on the OTCQB. The lack of an active market may impair the ability of holders of our common stock to sell their shares of common stock at the time they wish to sell them or at a price that they consider reasonable. The lack of an active market may also reduce the fair market value of the shares of our common stock.

We do not expect to pay any dividends in the foreseeable future.
 
We do not expect to declare dividends in the foreseeable future. We currently intend to retain cash to support our operations and to finance the growth and development of our business. There can be no assurance that we will have, at any time, sufficient surplus under Delaware law to be able to pay any dividends. If we do not pay dividends, the price of our common stock must appreciate for you to receive a gain on your investment in Zoom Telephonics.
 
Our directors, executive officers and principal stockholders own a significant percentage of our shares, which will limit your ability to influence corporate matters.
 
Our directors, executive officers and certain other principal stockholders owned approximately 42% percent of our outstanding Common Stock as of February 24, 2017.  Accordingly, these stockholders could have a significant influence over the outcome of any corporate transaction or other matter submitted to our stockholders for approval, including mergers, consolidations and the sale of all or substantially all of our assets and also could prevent or cause a change in control. The interests of these stockholders may differ from the interests of our other stockholders. Third parties may be discouraged from making a tender offer or bid to acquire us because of this concentration of ownership.
 
In 2015 we adopted an Internal Revenue Code Section 382 stockholder rights plan which could discourage potential acquisition proposals and could prevent, deter or delay a change in control of our company.
 
In November 2015 we adopted an Internal Revenue Code Section 382 stockholder rights plan (the “Rights Plan”) with the purpose of reducing the likelihood of an unintended “ownership change” and thus assisting in preserving the value of the tax benefits associated with our accumulated net operating losses.  The Rights Plan could have the effect, either alone or in combination provisions of our certificate of incorporation or Delaware law, of preventing, deterring or delaying a change in control of our company, even if a change in control would be beneficial to our stockholders.
 
Our ability to use our net operating losses (“NOLs”) may be negatively affected if there is an “ownership change” as defined under Section 382 of the Internal Revenue Code.
 
At December 31, 2016 we had approximately $54.0 million in federal NOLs. These deferred tax assets are currently fully reserved.  Under Internal Revenue Code Section 382 rules, if a change of ownership is triggered, our ability to use our NOLs can be negatively affected if there is an “ownership change” as defined under Internal Revenue Code Section 382. In general, an ownership change occurs whenever there is a shift in ownership by more than 50 percentage points by one or more 5% stockholders over a specified time period (generally three years). Given Internal Revenue Code Section 382’s broad definition, an ownership change could be the unintended consequence of otherwise normal market trading in the Company’s stock that is outside of the Company’s control. Similar plans have been adopted by a number of companies holding similar significant tax assets over the past several years.

The following discussion and analysis should be read in conjunction with the consolidated financial statements included elsewhere in this report and the information described under the caption "ITEM 1A - Risk Factors" above. Readers should also be cautioned that results of any reported period are often not indicative of results for any future period.
 
Overview
 
We derive our net sales primarily from sales of Internet access and other communications-related products, including cable modems and gateways, DSL modems and dial-up modems to retailers, distributors, Internet Service Providers and Original Equipment Manufacturers. We sell our products through a direct sales force and through independent sales agents. Our employees are located at our headquarters in Boston, Massachusetts.  We are experienced in electronics hardware, firmware, and software design and testing, regulatory certifications, product documentation, and packaging; and we use that experience in developing each product in-house or in partnership with suppliers who are typically based in Asia. Electronic assembly and testing of the Company’s products in accordance with our specifications is typically done in Asia.
 
From 1983 to July 2016 our headquarters was on South Street, near South Station in downtown Boston. Our principal executive offices are still near South Station, but our location changed in July 2016 to 99 High Street, Boston, MA 02110. Our current lease for this facility expires on June 30, 2019. We also lease a facility in Tijuana, Mexico. In November 2014 we signed a one-year lease with five one-year renewal options thereafter for an 11,390 square foot facility in Tijuana, Mexico. In September 2015, Zoom extended the term of the lease from December 1, 2015 through November 30, 2018. In September 2015, Zoom also signed a new lease for additional space in the adjacent building, which doubled our capacity. The term of the lease is from March 1, 2016 through November 30, 2018.
 
We continually seek to improve our product designs and manufacturing approach in order to improve product performance and reduce our costs. We pursue a strategy of outsourcing rather than internally developing our modem chipsets, which are application-specific integrated circuits that form the technology base for our modems. By outsourcing the chipset technology, we are able to concentrate our research and development resources on modem system design, leverage the extensive research and development capabilities of our chipset suppliers, and reduce our development time and associated costs and risks. As a result of this approach, we are able to quickly develop new products while maintaining a relatively low level of research and development expense as a percentage of net sales. We also outsource aspects of our manufacturing to contract manufacturers as a means of reducing our costs of production, and to provide us with greater flexibility in our production capacity.
 
Generally our gross margin for a given product depends on a number of factors including the type of customer to whom we are selling. The gross margin for retailers tends to be higher than for some of our other customers; but the sales, support, returns, and overhead costs associated with retailers also tend to be higher. Zoom’s sales to certain countries are currently handled by a single master distributor for each country, who handles the support and marketing costs within the country. Gross margin for sales to these master distributors tends to be low, since lower pricing to these distributors helps them to cover the support and marketing costs for their country.

As of February 28, 2017, Zoom had 30 full-time and part-time employees. Ten employees were engaged in research and development and quality control. Five employees were involved in operations, which manages production, inventory, purchasing, warehousing, freight, invoicing, shipping, collections, and returns. Nine employees were engaged in sales, marketing, and customer support. The remaining six employees performed executive, accounting, administrative, and management information systems functions. Zoom currently has 25 full-time employees and 5 employees working less than 5 days per week. Our dedicated personnel in Tijuana, Mexico are employees of our Mexican service provider and not included in our headcount. On February 28, 2017, Zoom had two consultants in sales and one consultant in information systems, none of whom are included in our headcount.
 
 The Company has experienced losses in the past, and is expected to continue to experience losses until sales grow significantly. The Company has experienced dramatic growth, with sales in 2016 up 65% over sales in 2015 and with sales in the fourth quarter of 2016 up 191% over sales in the fourth quarter of 2015. The Company expects year-over-year growth to continue due to a number of factors including the strength of the Motorola brand, new product introductions, increased shelf space, growing online retailer sales, and international expansion. Because of projected sales increases, the associated improved net income and its Financing Agreement, the Company expects to maintain acceptable levels of liquidity to meet its obligations as they become due for at least twelve months from the date of issuance of our annual filing with the Securities Exchange Commission.
 
  Zoom’s cash balance on December 31, 2016 was $180 thousand, and its net loss for the fiscal year ended December 31, 2016 was approximately $2.9 million. On December 31, 2016, Zoom had $1.3 million in bank debt for a $3.0 million line of credit, working capital of $3.4 million, and a current ratio of 1.7. We may need to raise additional funds in future periods to fund our operations. We may seek to raise necessary funds through a combination of publicly or private equity offerings, debt financings, other financing mechanisms, or strategic arrangements. We may not be able to obtain additional financing on terms favorable to us, if at all.
 
Critical Accounting Policies and Estimates
 
Following is a discussion of what we view as our more significant accounting policies and estimates. As described below, management judgments and estimates must be made and used in connection with the preparation of our consolidated financial statements. We have identified areas where material differences could result in the amount and timing of our net sales, costs, and expenses for any period if we had made different judgments or used different estimates.
 
Revenue Recognition. We primarily sell hardware products to our customers. The hardware products include dial-up modems, DSL modems, cable modems, and local area networking equipment.
 
We derive our net sales primarily from the sales of hardware products to four types of customers:
 
● 
Computer peripherals retailers,
 
● 
Computer product distributors,
 
● 
Internet service providers, and
 
● 
OEMs.
 
We recognize hardware net sales for our customers at the point when the customers take legal ownership of the delivered products. Legal ownership passes from Zoom to the customer based on the contractual Free on Board (“FOB”) point specified in signed contracts and purchase orders, which are both used extensively. Many of our customer contracts or purchase orders specify FOB destination, which means that title and risk remain with the seller until it has delivered the goods to the location specified in the contract. We verify the delivery date on all significant FOB destination shipments made during the last 10 business days of each quarter.
 
Our net sales of hardware include reductions resulting from certain events which are characteristic of the sales of hardware to retailers of computer peripherals. These events are product returns, certain sales and marketing incentives, price protection refunds, and consumer mail-in and in-store rebates. Each of these is accounted for as a reduction of net sales based on detailed management estimates, which are reconciled to actual customer or end-consumer credits on a monthly or quarterly basis.
 
               Product Returns. Products are returned by retail stores and distributors for inventory balancing, contractual stock rotation privileges, and warranty repair or replacements. We estimate the sales and cost value of expected future product returns of previously sold products. Our estimates for product returns are based on recent historical trends plus estimates for returns prompted by, among other things, announced stock rotations and announced customer store closings. Management reviews historical returns, current economic trends, and changes in customer demand and acceptance of our products when estimating sales return allowances. The estimate for future returns is recorded as a reserve against accounts receivable, a reduction in our net sales, and the corresponding change to inventory reserves and cost of sales.
 
Price Protection Refunds. We have a policy of offering price protection to certain of our retailer and distributor customers for some or all their inventory. Under the price protection policies, when we reduce our prices for a product, the customer receives a credit for the difference between the original purchase price and our reduced price for their unsold inventory of that product. Our estimates for price protection refunds are based on a detailed understanding and tracking by customer and by sales program. Estimated price protection refunds are recorded in the same period as the announcement of a pricing change. Information from customer inventory-on-hand reports or from direct communications with the customers is used to estimate the refund, which is recorded as a reduction of net sales and a reserve against accounts receivable.
 
 
 
21
 
 
Sales and Marketing Incentives. Many of our retailer customers require sales and marketing support funding, usually set as a percentage of our sales in their stores. The incentives were reported as reductions in our net sales.
 
Consumer Mail-In and In-Store Rebates.  Our estimates for consumer mail-in and in-store rebates are based on a detailed understanding and tracking by customer and sales program, supported by actual rebate claims processed by the rebate redemption centers plus an accrual for an estimated lag in processing at the redemption centers. The estimate for mail-in and in-store rebates is recorded as a reserve against accounts receivable and a reduction of net sales in the same period that the rebate obligation was triggered.
 
Accounts Receivable Valuation. We establish accounts receivable valuation allowances equal to the above-discussed net sales adjustments for estimates of product returns, price protection refunds, consumer rebates, and general bad debt reserves. These allowances are reduced as actual credits are issued to the customer's accounts.
 
Inventory Valuation and Cost of Goods Sold.  Inventory is valued at the lower of cost, determined by the first-in, first-out method, or its net realizable value. We review inventories for obsolete slow moving products each quarter and make provisions based on our estimate of the probability that the material will not be consumed or that it will be sold below cost. Additionally, material product certification costs on new products are capitalized and amortized over the expected period of value of the respective products.
 
Valuation and Impairment of Deferred Tax Assets. As part of the process of preparing our financial statements we estimate our income tax expense and deferred income tax position. This process involves the estimation of our actual current tax exposure together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included in our balance sheet. We then assess the likelihood that our deferred tax assets will be recovered from future taxable income. To the extent we believe that recovery is not likely, we establish a valuation allowance. Changes in the valuation allowance are reflected in the statement of operations.
 
Significant management judgment is required in determining our provision for income taxes and any valuation allowances. We have recorded a 100% valuation allowance against our deferred income tax assets. It is management's estimate that, after considering all available objective evidence, historical and prospective, with greater weight given to historical evidence, it is more likely than not that these assets will not be realized. If we establish a record of continuing profitability, at some point we will be required to reduce the valuation allowance and recognize an equal income tax benefit which will increase net income in that period(s).
 
As of December 31, 2016 the Company had federal net operating loss carry forwards of approximately $54.0 million that are available to offset future taxable income. They are due to expire in varying amounts from 2018 to 2036. As of December 31, 2016, the Company had Massachusetts state net operating loss carry forwards of approximately $7.3 million that are available to offset future taxable income. They are due to expire in varying amounts from 2031 through 2036.
 
Results of Operations
 
Zoom’s net sales of $17.8 million for the fiscal year ended December 31, 2016 (“FY 2016”) were up 65.3% from $10.8 million for the fiscal year ended December 31, 2015 (“FY 2015”). Zoom reported a net loss of $2.9 million or $0.21 per share for FY 2016 compared to a net loss of $833 thousand or $0.09 per share for FY 2015. Gross profit was $5.4 million for FY 2016, up $2.0 million from $3.4 million for FY 2015. Gross margin was down slightly to 30.1% in FY 2016 from 31.5% in FY 2015 due primarily to increased amortization of certification costs associated with new products.

Year Ended December 31, 2016 Compared to Year Ended December 31, 2015
 
The following is a discussion of the major categories of our consolidated statement of operations, comparing the consolidated financial results for the year ended December 31, 2016 with the year ended December 31, 2015.
 
Net Sales. Our total net sales increased year-over-year by $7.0 million or 65.3%. The growth in sales is directly attributable to Motorola branded cable modems. In both 2016 and 2015 we primarily generated our sales by selling broadband and dial-up modems via retailers, distributors, and Internet Service Providers. Zoom sales of Dial-up modems decreased $537 thousand or 46.4%. Our Broadband modems, Wireless and Other Products sales increased year-over-year by $7.6 million or 78.7%. The increase in sales was primarily attributable to Motorola branded broadband products, and reflects continued shift away from dial-up modems to cable modems and other broadband technologies.
 
Zoom focuses on maintaining appropriate inventory levels. We have also reviewed our obsolete inventory reserve. Zoom determines its inventory reserve for obsolete and slow moving products by reviewing for each Zoom product its past and forecasted sales, open sales orders, customer inventory levels, planned product changes, and anticipated price drops.  Zoom takes a reserve if this data suggests that Zoom is likely to need to sell a product's inventory below its current inventory cost in order to sell the product’s entire inventory within the next 12 months.

 As shown in the table below our net sales in North America increased $7.0 million to $17.6 million in 2016 from $10.6 million in 2015. Generally Zoom’s lower sales outside North America reflect the fact that cable modems are sold successfully through retailers in the US but not in most countries outside the US, due primarily to variations in government regulations.

Relatively few customers account for a substantial portion of the Company’s revenues.  In 2016 three customers accounted for 82% of our total net sales, with our largest customer accounting for 29% of our net sales. At December 31, 2016, three customers accounted for 86% of our gross accounts receivable, with our largest customer representing 56% of our gross accounts receivable. In 2015 three customers accounted for 77% of the Company’s total net sales with our largest customer accounting for 46% of our net sales. At December 31, 2015, three customers accounted for 93% of our gross accounts receivable, with our largest customer representing 67% of our gross accounts receivable.
 
Because of our customer concentration, our net sales and operating income could fluctuate significantly due to changes in political or economic conditions or the loss, reduction of business, or less favorable terms for any of our significant customers.
 
Gross Profit. Gross profit was $5.4 million for FY 2016, up $2 million from $3.4 million for FY 2015. Gross margin was down slightly to 30.1 % in FY 2016 from 31.5% in FY 2015 due primarily to increased amortization of certification costs associated with new products.
 
Operating Expense. Total operating expense increased by $4.1 million from $4.1 million in 2015 to $8.2 million in 2016. Total operating expense as a percentage of net sales increased from 38.4% in 2015 to 46.3% in 2016.  The table below illustrates the change in operating expense.

Selling Expense. Selling expense increased to $5.2 million in 2016 from $1.6 million in 2015. Selling expense as a percentage of net sales was 29.1% in 2016 and 14.6% in 2015. The $3.6 million increase in selling expense was due primarily to Motorola trademark costs and increased advertising expenses.
 
General and Administrative Expense. General and administrative expense increased to $1.5 million in 2016 from $1.2 million in 2015. General and administrative expense as a percentage of net sales was 8.6% in 2016 and 11.4% in 2015. The $312 thousand increase in general and administration expense was primarily due to increased personnel and stock option costs, and audit and legal expenses.
 
Research and Development Expense.  Research and development expense increased to $1.5 million in 2016 from $1.3 million in 2015.  Research and development expense as a percentage of net sales decreased to 8.5% in 2016 from 12.4% in 2015. The $181 thousand increase in research and development expense was primarily due to increased personnel expenses.
 
Other Income (Expense).  Other income (expense), net was $(42) thousand in 2016. Loan interest and fees of approximately $84 thousand were reduced by one-time miscellaneous income of approximately $44 thousand received from class action settlement. Other income (expense), net was $(86) thousand in 2015, primarily due to loan related interest expense.
 
Income Tax Expense (Benefit). We recorded income tax from our operations in Mexico, which was negligible in both 2015 and 2016.
 
Liquidity and Capital Resources
 
Zoom’s cash balance on December 31, 2016 was $180 thousand compared to $1.85 million on December 31, 2015. The Company raised net proceeds of approximately $1.5 million in a private placement in October 2016, increased bank debt $1.3 million, and increased accounts payable and accrued liabilities by $1.8 million. These increases were offset by a loss of $2.9 million during FY 2016, a $2.2 million increase in net inventory, and a $1.4 million increase in net accounts receivable. On December 31, 2016, Zoom had $1.3 million in bank debt for a $3.0 million line of credit, working capital of $3.4 million, and a current ratio of 1.7.

On May 18, 2015, the Company announced licensing of the Motorola trademark for cable modems and gateways for the U.S. and Canada for five years starting January 2016 (the “License Agreement”).
 
On August 8, 2016, Zoom entered into an amendment to the License Agreement with Motorola Mobility LLC (the “Amendment”).  The Amendment expands Zoom’s exclusive license to use the Motorola trademark to a wide range of authorized channels worldwide, and expands the license from cable modems and gateways to also include consumer routers, WiFi range extenders, home powerline network adapters, and access points. The License Agreement, as amended, has a five-year term beginning January 1, 2016 through December 31, 2020.
 
On December 18, 2012, the Company entered into a Financing Agreement with Rosenthal & Rosenthal, Inc. (the “Financing Agreement”). The Financing Agreement originally provided for up to $1.75 million of revolving credit, subject to a borrowing base formula and other terms and conditions. The Financing Agreement continued until November 30, 2014 with automatic renewals from year to year thereafter, unless sooner terminated by either party. The lender has the right to terminate the Financing Agreement at any time on 60 days’ prior written notice. Borrowings are secured by all of the Company assets including intellectual property. The Financing Agreement contains several covenants, including a requirement that the Company maintain tangible net worth of not less than $2.5 million and working capital of not less than $2.5 million.
 
On March 25, 2014, the Company entered into an amendment to the Financing Agreement (the “Amendment”) with an effective date of January 1, 2013. The Amendment clarified the definition of current assets in the Financing Agreement, reduced the size of the revolving credit line to $1.25 million, and revised the financial covenants so that Zoom is required to maintain tangible net worth of not less than $2.0 million and working capital of not less than $1.75 million.
 
On October 29, 2015, the Company entered into a second amendment to the Financing Agreement (the “Second Amendment”). Retroactive to October 1, 2015, the Second Amendment eliminated $2,500 in monthly charges for the Financing Agreement. Effective December 1, 2015, the Second Amendment reduces the effective rate of interest to 2.25% plus an amount equal to the higher of prime rate or 3.25%.
 
On July 19, 2016, the Company entered into a third amendment to the Financing Agreement. The Amendment increased the size of the revolving credit line to $2.5 million effective as of date of the amendment.
 
On September 1, 2016, the Company entered into a fourth amendment to the Financing Agreement. The Amendment increased the size of the revolving credit line to $3.0 million effective with the date of this amendment.
 
The Company is required to calculate its covenant compliance on a quarterly basis. As of December 31, 2016, the Company was in compliance with both its working capital and tangible net worth covenants. At December 31, 2016, the Company’s tangible net worth was approximately $3.6 million, while the Company’s working capital was approximately $3.4 million.
 
Off-Balance Sheet Arrangements
 
In 2006 the Company entered into a maquiladora agreement with North American Production Sharing, Inc (“NAPS”). This agreement provides that NAPS provide certain personnel and other services for a production facility in Mexico on our behalf. In order to facilitate Zoom’s current and planned increase in production demand, driven in part by the launch of Motorola branded products, Zoom has entered into a first amendment to the Production Sharing Agreement (“PSA”). This amendment extends its existing agreement through September 25, 2019. Any related assets, liabilities, or expenses are reported in the accompanying financial statements. Additionally, the Company is obligated to pay future minimum required royalty payments associated with certain licensing agreements which are not included in our balance sheet.

ITEM 9A – CONTROLS AND PROCEDURES
 
Management’s Report on Disclosure Controls and Procedures
 
We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Securities Exchange Act of 1934 reports is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer who is also our Acting Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, as ours are designed to do, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
 
As of December 31, 2016 we carried out an evaluation, under the supervision and with the participation of our management including our Chief Executive Officer and Acting Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934. Based upon that evaluation, our Chief Executive Officer and Acting Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report in enabling us to record, process, summarize and report information required to be included in our periodic SEC filings within the required time period.
 
Management’s Report on Internal Control over Financial Reporting
 
Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Judgments by management are also required in evaluating the expected benefits and related costs of control procedures. The objectives of internal control include providing management with reasonable, but not absolute, assurance that assets are safeguarded against loss from unauthorized use or disposition, and that transactions are executed in accordance with management’s authorization and recorded properly to permit the preparation of consolidated financial statements in conformity with accounting principles generally accepted in the US. Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2016.  In making this assessment, our management used the criteria set forth in 2013 by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control-Integrated Framework. Our management has concluded that as of December 31, 2016, our internal control over financial reporting is effective in providing reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with US generally accepted accounting principles. Our management reviewed the results of their assessment with our Board of Directors.
 
 
 
26
 
 
This annual report does not include an attestation report of the Company’s registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Company’s registered public accounting firm pursuant to a permanent exemption from the internal control audit requirements of Section 404(b) of the Sarbanes-Oxley Act of 2002.
 
Inherent limitations on effectiveness of controls
 
Internal control over financial reporting has inherent limitations which include but are not limited to the use of independent professionals for advice and guidance, interpretation of existing and/or changing rules and principles, segregation of management duties, scale of organization, and personnel factors. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial reporting also can be circumvented by collusion or improper management override. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements on a timely basis, however these inherent limitations are known features of the financial reporting process and it is possible to design into the process safeguards to reduce, though not eliminate, this risk. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
 
Changes in Internal Control over Financial Reporting
 
There have been no significant changes in our internal controls over financial reporting that occurred during the fiscal year ended December 31, 2016 that have materially or are reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 
To the Audit Committee of the
Board of Directors and Stockholders
of Zoom Telephonics, Inc.
 
We have audited the accompanying consolidated balance sheets of Zoom Telephonics, Inc. and its wholly owned subsidiary (together the “Company”) as of December 31, 2016 and 2015, and the related consolidated statements of operations, stockholders’ equity and cash flows for the years then ended. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.
 
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement.  The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.  We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Zoom Telephonics, Inc. and its wholly owned subsidiary as of December 31, 2016 and 2015, and the consolidated results of their operations and their cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America.

Notes to Consolidated Financial Statements
Years Ended December 31, 2016 and 2015
 
(1)           NATURE OF OPERATIONS
 
Zoom Telephonics, Inc. and its wholly owned subsidiary MTRLC LLC (collectively the "Company"), designs, produces, markets and supports cable modems and other communication products.
 
(2)           SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
(a)  Basis of Presentation and Use of Estimates
 
The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP). All significant intercompany balances and transactions have been eliminated in the consolidation.
 
The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expense during the reporting period. Actual results may differ from those estimates. Significant estimates made by the Company include: 1) allowance for doubtful accounts for accounts receivable (collectability and sales returns) and asset valuation allowance for deferred income tax assets; 2) write-downs of inventory for slow-moving and obsolete items, and market valuations; 3) stock based compensation; 4) management’s assessment of going concern; 5) and estimated life of certification costs.
 
(b)  Cash and Cash Equivalents
 
All highly liquid investments with original maturities of less than 90 days from the date of purchase are classified as cash equivalents. Cash equivalents consist exclusively of money market funds. The Company has deposits at a limited number of financial institutions with federally insured limits. Balances of cash and cash equivalents at these institutions can be in excess of the insured limits. However, the Company believes that the institutions are financially sound and there is only nominal risk of loss.
 
(c)   Inventories
 
Inventories are stated at the lower of cost, determined using the first-in, first-out method, or net realizable value. Consigned inventory is held at third-party locations. The Company retains title to the inventory until purchased by the third-party. Consigned inventory, consisting of finished goods, was approximately $442,300 and $119,100 at December 31, 2016 and 2015, respectively.
 
(d)   Equipment
 
Equipment is stated at cost, less accumulated depreciation. Depreciation of equipment is provided using the straight-line method over the estimated useful lives of the assets.
 
(e)   Impairment of Long-Lived Assets
 
Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.
 
Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset or asset group to undiscounted future net cash flows expected to be generated by the asset or asset group. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds their fair value. Assets to be disposed of are reported at the lower of the carrying amount or fair value less cost to sell.
 
 
F-7
 
 
(f)    Income Taxes
 
Deferred income taxes are provided on the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and on net operating loss and tax credit carry forwards. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred income tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided for that portion of deferred tax assets not expected to be realized.
 
(g)  Earnings (Loss) Per Common Share
 
Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period.  Diluted earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares and dilutive potential common shares outstanding during the period. Under the treasury stock method, the unexercised options are assumed to be exercised at the beginning of the period or at issuance, if later. The assumed proceeds are then used to purchase common shares at the average market price during the period.
 
Potential common shares for which inclusion would have the effect of increasing diluted earnings per share (i.e., anti-dilutive) are excluded from the computation. Options to purchase 2,190,744 shares of common stock at December 31, 2016 and 2,761,500 shares of common stock as of December 31, 2015 were outstanding, but not included in the computation of diluted earnings per share as their effect would be anti-dilutive.
 
(h)  Revenue Recognition
 
The Company primarily sells hardware products to its customers. The hardware products include dial-up modems, DSL modems, cable modems, embedded modems, ISDN modems, telephone dialers, and wireless and wired networking equipment. The Company does not sell software.
 
The Company derives its net sales primarily from the sales of hardware products to computer peripherals retailers, computer product distributors, OEMs, and direct to consumers and other channel partners via the Internet. The Company accounts for point-of-sale taxes on a net basis.
 
The Company recognizes net hardware sales at the point when the customers take legal ownership of the delivered products. Legal ownership passes to the customer based on the contractual delivery terms specified in signed contracts and purchase orders, which are both used extensively. Many customer contracts or purchase orders specify FOB destination, which means buyer takes delivery of goods once the goods arrive at the buyers dock.
 
When the Company consigns inventory to a retailer, sales revenue for an item in that inventory is recognized when that item is sold by the retailer to a customer. The item remains in the Company’s inventory when it is consigned, and moves out of Company inventory when the item is sold by the retailer.
 
 The Company's net sales of hardware are reduced by certain events that are characteristic of the sales of hardware to retailers of computer peripherals. These events are product returns, certain sales and marketing incentives, price protection refunds, and consumer and in-store mail-in rebates. These are accounted for as a reduction of net sales based on management estimates, which are reconciled to actual customer or end-consumer credits on a monthly or quarterly basis.
 
The estimates for product returns are based on recent historical trends plus estimates for returns prompted by announced stock rotations, announced customer store closings, etc. Management analyzes historical returns, current economic trends, and changes in customer demand and acceptance of the Company's products when evaluating the adequacy of sales return allowances. Product return reserves were approximately $343.3 thousand and $322.0 thousand at December 31, 2016 and 2015, respectively. The Company's estimates for price protection refunds require a detailed understanding and tracking by customer, by sales program. Estimated price protection refunds are recorded in the same period as the announcement of a pricing change. Information from customer inventory-on-hand reports or from direct communications with the customers is used to estimate the refund, which is recorded as a reserve against accounts receivable and a reduction of current period revenue. Price protection reserves were negligible at December 31, 2016 and $131.3 thousand at December 31, 2015. The Company's estimates for consumer mail-in rebates are comprised of actual rebate claims processed by the rebate redemption centers plus an accrual for an estimated lag in processing. The Company's estimates for store rebates are comprised of actual credit requests from the eligible customers. Rebate reserves were approximately $38.4 thousand at December 31, 2016 and $0 at December 31, 2015. Additionally, sales and marketing incentive reserves were approximately $109.7 thousand and $22.0 thousand at December 31, 2016 and 2015, respectively. The Company’s allowances for doubtful accounts were approximately $16.0 thousand and $8.1 thousand at December 31, 2016 and 2015, respectively. These allowances are included in allowances for accounts receivable on the accompanying consolidated balance sheets.
 
 
F-8
 
 
(i)   Fair Value of Financial Instruments
 
The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels:
 
Level 1 - Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access.
 
Level 2 - Inputs are inputs (other than quoted prices included within Level 1) that are observable for the asset or liability, either directly or indirectly.
 
Level 3 - Inputs include unobservable inputs for the asset or liability and rely on management's own assumptions about the assumptions that market participants would use in pricing the asset or liability. (The unobservable inputs should be developed based on the best information available in the circumstances and may include the Company’s own data.)
 
Financial instruments consist of cash and cash equivalents, accounts receivable, bank debt, and accounts payable. Due to the short-term nature and payment terms associated with these instruments, their carrying amounts approximate fair value.
 
(j)    Stock-Based Compensation
 
Compensation cost for awards is generally recognized over the required service period based on the estimated fair value of the awards on their grant date. Fair value is determined using the Black-Scholes option-pricing model wherein the discount rate is based on published daily treasury interest rates for zero-coupon bonds available from the US Treasury. Volatility is based on the historical volatility over a period that is commensurate with the expected life of the option granted.
 
(k)   Advertising Costs
 
Advertising costs are expensed as incurred and reported in selling expense in the accompanying consolidated statements of operations, and include costs of advertising, production, trade shows, and other activities designed to enhance demand for the Company's products. There are no deferred advertising costs in the accompanying consolidated balance sheets. The Company reported advertising costs of approximately $1.34 million in 2016 and $459.5 thousand in 2015.
 
(l)   Foreign Currencies
 
The Company generates a portion of its revenues in markets outside North America principally in transactions denominated in foreign currencies, which exposes the Company to risks of foreign currency fluctuations. Foreign currency transaction gains and losses are reflected in operations and were not material for any period presented.  The Company does not use derivative financial instruments for hedging purposes.
 
(m) Warranty Costs
 
The Company provides for the estimated costs that may be incurred under its standard warranty obligations, based on actual historical repair costs. The reserve for the provision for warranty costs was $23,310 and $21,475 at December 31, 2016 and 2015, respectively.
 
(n) Shipping and Freight Costs
 
The Company records the expense associated with customer-delivery shipping and freight costs in selling expense. The Company reported shipping and freight costs of $396.3 thousand in 2016 and $247.1 thousand in 2015.

(o) Recently Issued Accounting Pronouncements
 
In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, "Revenue from Contracts with Customers," which is a comprehensive revenue recognition standard that will supersede nearly all existing recognize revenue guidance under U.S. GAAP. This standard is effective for interim and annual periods beginning after December 15, 2017, and either full retrospective adoption or modified retrospective adoption is permitted. The Company is still in the process of evaluating the potential impact that the adoption of ASU 2014-09 may have on its consolidated financial statements.
 
In August 2014, the FASB issued ASU No. 2014-15, "Presentation of Financial Statements — Going Concern." This standard requires management to evaluate for each annual and interim reporting period whether it is probable that the reporting entity will not be able to meet its obligations as they become due within one year after the date that the financial statements are issued. If the entity is in such a position, the standard provides for certain disclosures depending on whether or not the entity will be able to successfully mitigate its going concern status. This guidance is effective for annual periods ending after December 15, 2016 and interim periods within annual periods beginning after December 15, 2016. The Company has implemented this standard and included the required disclosures in the consolidated financial statements.
 
In July 2015, the FASB issued ASU No. 2015-11, “Inventory (Topic 330): Simplifying the Measurement of Inventory.” Currently, all inventory is measured at the lower of cost or market. ASU 2015-11 changes the measurement principle for inventory from the lower of cost or market to the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business less reasonably predictable costs of completion, disposal and transportation. The standard is effective for annual reporting periods beginning after December 15, 2015, which for the Company commenced with the year beginning January 1, 2016. Prospective application is required. The Company does not believe the implementation of this standard has a material impact on the Company’s consolidated financial statements.
 
In March 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 requires that a lessee recognize the assets and liabilities that arise from operating leases. A lessee should recognize in the balance sheets, a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term (the lease asset). For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. Public business entities should apply the amendments in ASU 2016-02 for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted. The Company is currently evaluating the potential impact that the adoption of ASU 2016-02 may have on its consolidated financial statements.
 
In March 2016, the FASB issued ASU No. 2016-09, “Compensation – Stock Compensation.” ASU 2016-09 simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Some of the simplified areas apply only to nonpublic entities. ASU 2016-09 is effective for public business entities for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted in any interim or annual period. If an entity early adopts ASU 2016-09 in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. Methods of adoption vary according to each of the amendment provisions. The adoption of ASU 2016-09 is not expected to have a material impact on the consolidated financial statements.
 
In April 2016, the FASB issued ASU No. 2016-10, "Revenue from Contracts with Customers — Identifying Performance Obligations and Licensing." ASU 2016-10 does not change the core principle of the guidance, rather it clarifies the identification of performance obligations and the licensing implementation guidance, while retaining the related principles for those areas. ASU 2016-10 clarifies the guidance in ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)," which is not yet effective. The effective date and transition requirements for ASU 2016-10 are the same as for ASU 2014-09, which was deferred by one year by ASU No. 2015-14, "Revenue from Contracts with Customers — Deferral of the Effective Date." Public business entities should adopt the new revenue recognition standard for annual reporting periods beginning after December 15, 2017, including interim periods within that year. Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim periods within that year. The Company is currently evaluating the potential impact that the adoption of ASU 2016-10 may have on its consolidated financial statements.
 
 
 
F-10
 
 
In May 2016, the FASB issued ASU No. 2016-12, "Revenue from Contracts with Customers — Narrow- Scope Improvements and Practical Expedients." ASU 2016-12 does not change the core principle of the guidance, rather it affects only certain narrow aspects of Topic 606, including assessing collectability, presentation of sales taxes, noncash consideration, and completed contracts and contract modifications at transition. ASU 2016-12 affects the guidance in ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)," which is not yet effective. The effective date and transition requirements for ASU 2016-12 are the same as for ASU 2014-09, which was deferred by one year by ASU No. 2015-14, "Revenue from Contracts with Customers —Deferral of the Effective Date." Public business entities should adopt the new revenue recognition standard for annual reporting periods beginning after December 15, 2017, including interim periods within that year. Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim periods within that year. The Company is currently evaluating the potential impact that the adoption of ASU 2016-12 may have on its consolidated financial statements.
 
In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments Credit Losses —Measurement of Credit Losses on Financial Instruments." ASU 2016-13 requires a financial asset (or group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. ASU 2016-13 is effective for public business entities that are SEC filers for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted in any interim or annual period for fiscal years beginning after December 15, 2018. An entity should apply the amendments in ASU 2016-13 through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (modified-retrospective approach). The Company is currently evaluating the potential impact that the adoption of ASU 2016-13 may have on its consolidated financial statements, however, it does not expect it to have a material effect.
 
(p) Other Assets
 
Other assets are stated at cost, less accumulated amortization. Certain certification costs incurred that are necessary to market and sell products are capitalized and reported as “other assets” in the accompanying consolidated balance sheets when the costs are measurable, significant, and whose related products are projected to generate revenue beyond twelve months. These costs are amortized over an eighteen-month period, beginning when the related products are available to be sold. Total certification costs capitalized during the year ended December 31, 2016 were $473,000, with related amortization expense of $457,142 in 2016. Total certification costs capitalized during the year ended December 31, 2015 were $655,000, with related amortization expense of $81,951 in 2015.
 
(3)           LIQUIDITY
 
Zoom’s cash balance on December 31, 2016 was $180 thousand compared to $1.85 million on December 31, 2015. The Company raised $1.5 million in a private placement in October 2016 and increased bank debt $1.3 million. These increases were offset by a year 2016 loss of $2.9 million, a $2.2 million increase in net inventory, a $1.8 million increase in accounts payable and accrued liabilities, and a $1.4 million increase in net accounts receivable. On December 31, 2016 Zoom had $1.3 million in bank debt for a $3.0 million line of credit, working capital of $3.4 million, and a current ratio of 1.7.
 
On December 18, 2012, the Company entered into a Financing Agreement with Rosenthal & Rosenthal, Inc. (the “Financing Agreement”). The Financing Agreement originally provided for up to $1.75 million of revolving credit, subject to a borrowing base formula and other terms and conditions. The Financing Agreement continued until November 30, 2014 with automatic renewals from year to year thereafter, unless sooner terminated by either party. The lender has the right to terminate the Financing Agreement at any time on 60 days’ prior written notice. Borrowings are secured by all of the Company assets including intellectual property. The Financing Agreement contains several covenants, including a requirement that the Company maintain tangible net worth of not less than $2.5 million and working capital of not less than $2.5 million.
 
On March 25, 2014, the Company entered into an amendment to the Financing Agreement (the “Amendment”) with an effective date of January 1, 2013. The Amendment clarified the definition of current assets in the Financing Agreement, reduced the size of the revolving credit line to $1.25 million, and revised the financial covenants so that Zoom is required to maintain tangible net worth of not less than $2.0 million and working capital of not less than $1.75 million.
 
 
 
F-11
 
 
On October 29, 2015, the Company entered into a second amendment to the Financing Agreement (the “Second Amendment”). Retroactive to October 1, 2015, the Second Amendment eliminated $2,500 in monthly charges for the Financing Agreement. Effective December 1, 2015, the Second Amendment reduces the effective rate of interest to 2.25% plus an amount equal to the higher of prime rate or 3.25%.
 
On July 19, 2016, the Company entered into a third amendment to the Financing Agreement. The Amendment increased the size of the revolving credit line to $2.5 million effective as of date of the amendment.
 
On September 1, 2016, the Company entered into a fourth amendment to the Financing Agreement. The Amendment increased the size of the revolving credit line to $3.0 million effective with the date of this amendment.
 
The Company is required to calculate its covenant compliance on a quarterly basis. As of December 31, 2016, the Company was in compliance with both its working capital and tangible net worth covenants. At December 31, 2016, the Company’s tangible net worth was approximately $3.6 million, while the Company’s working capital was approximately $3.4 million.
 
The Company raised net proceeds of approximately $1.5 million from a private placement in October 2016. The Company raised $3.42 million from a private placement in September 2015 and raised $229 thousand from a rights offering in July 2015.
 
The Company has experienced losses in the past, and is expected to continue to experience losses until sales grow significantly. The Company has experienced dramatic growth, with sales in 2016 up 65% over sales in 2015 and with sales in the fourth quarter of 2016 up 191% over sales in the fourth quarter of 2015. The Company expects year-over-year growth to continue due to a number of factors including the strength of the Motorola brand, new product introductions, increased shelf space, growing online retailer sales, and international expansion. Because of projected sales increases, the associated improved net income and its Financing Agreement, the Company expects to maintain acceptable levels of liquidity to meet its obligations as they become due for at least twelve months from the date of issuance of our annual filing with the Securities Exchange Commission.

(6)           COMMITMENTS AND CONTINGENCIES
 
(a)  Lease Obligations
 
In June 2016 the Company signed a three year sub-lease agreement for 11,480 square feet on the 28th floor of 99 High Street, Boston, MA 02110, The lease for this facility expires on June 30, 2019.
 
The Company performs most of the final assembly, testing, packaging, warehousing and distribution at a production and warehouse facility in Tijuana, Mexico. In November 2014, the Company signed a one-year lease with five one-year renewal options thereafter for an 11,390 square foot facility. In September 2015, the Company extended the term of the lease from December 1, 2015 through November 30, 2018. In September 2015, the Company also signed a new lease for additional space in the adjacent building, which doubles our existing capacity. The term of the lease is from March 1, 2016 through November 30, 2018 with early access granted as of December 1, 2015.
 
In order to facilitate the Company’s current and planned increase in production demand, driven in part by the launch of Motorola branded products, the Company has committed with North American Production Sharing, Inc. (“NAPS”) to extend its existing lease used in connection with the Production Sharing Agreement (“PSA”) entered into between the Company and NAPS. The extension term is December 1, 2015 through November 30, 2018 and allows the Company to contract additional Mexico personnel to work in the Tijuana facility.
 
Rent expense for all of the Company's leases was $500.0 thousand in 2016 and $363.8 thousand in 2015.
 
As of December 31, 2016, the Company's estimated future minimum committed rental payments, excluding executory costs, under the operating leases described above to their expiration or the earliest possible termination date, whichever is sooner, are $523.6 thousand for 2017, $526.3 thousand for 2018, and $218.1 thousand for 2019. There are no future minimum committed rental payments that extend beyond 2019.
 
(b)  Contingencies
 
The Company is party to various lawsuits and administrative proceedings arising in the ordinary course of business. The Company evaluates such lawsuits and proceedings on a case-by-case basis, and its policy is to vigorously contest any such claims which it believes are without merit.
 
The Company reviews the status of its legal proceedings and records a provision for a liability when it is considered probable that both a liability has been incurred and the amount of the loss can be reasonably estimated. This review is updated periodically as additional information becomes available. If either or both of the criteria are not met, the Company reassesses whether there is at least a reasonable possibility that a loss, or additional losses, may be incurred. If there is a reasonable possibility that a loss may be incurred, the Company discloses the estimate of the amount of the loss or range of losses, that the amount is not material, or that an estimate of the loss cannot be made. The Company expenses its legal fees as incurred.

As of December 31, 2016 the Company had federal net operating loss carry forwards of approximately $53,981,000 which are available to offset future taxable income. They are due to expire in varying amounts from 2018 to 2036. As of December 31, 2016, the Company had Massachusetts state net operating loss carry forwards of approximately $7,342,000 which are available to offset future taxable income. They are due to expire in varying amounts from 2031 through 2036. A valuation allowance has been established for the full amount of deferred income tax assets as management has concluded that it is more-likely than-not that the benefits from such assets will not be realized.
 
The Company reviews annually the guidance for the financial statement recognition, measurement and disclosure of uncertain tax positions recognized in the financial statements. Tax positions must meet a "more-likely-than-not" recognition threshold. At December 31, 2016 and 2015, the Company did not have any uncertain tax positions. No interest and penalties related to uncertain tax positions were accrued at December 31, 2016 and 2015.
 
The Company files income tax returns in the United States and Mexico. Tax years subsequent to 2012 remain subject to examination for both US federal and state tax reporting purposes. Tax years subsequent to 2010 remain subject to examination for Mexico tax reporting purposes.
 
 (9)        SIGNIFICANT CUSTOMERS
 
The Company sells its products primarily through high-volume distributors and retailers, internet service providers, telephone service providers, value-added resellers, PC system integrators, and OEMs. The Company supports its major accounts in their efforts to discern strategic directions in the market, to maintain appropriate inventory levels, and to offer a balanced selection of attractive products.

(11)         DEPENDENCE ON KEY SUPPLIERS
 
The Company participates in the PC peripherals industry, which is characterized by aggressive pricing practices, continually changing customer demand patterns and rapid technological developments. The Company's operating results could be adversely affected should the Company be unable to successfully anticipate customer demand accurately; manage its product transitions, inventory levels and manufacturing process efficiently; distribute its products quickly in response to customer demand; differentiate its products from those of its competitors or compete successfully in the markets for its new products.
 
The Company depends on many third-party suppliers for key components contained in its product offerings. For some of these components, the Company may only use a single source supplier, in part due to the lack of alternative sources of supply. In 2016, the Company had one supplier that provided 92% of the Company's purchased inventory. In 2015 the Company had two suppliers that provided 85% of the Company's purchased inventory.

(13)         BANK CREDIT LINE
 
On December 18, 2012, the Company entered into a Financing Agreement with Rosenthal & Rosenthal, Inc. (the “Financing Agreement”). The Financing Agreement provided for up to $1.75 million of revolving credit, subject to a borrowing base formula and other terms and conditions as specified in the Financing Agreement. The Financing Agreement continued until November 30, 2014 and automatically renews from year to year thereafter, unless sooner terminated by either party as specified in the Financing Agreement. The Lender shall have the right to terminate the Financing Agreement at any time by giving the Company sixty days’ prior written notice. Borrowings are secured by all of the Company assets including intellectual property. The Loan Agreement contained several covenants, including a requirement that the Company maintain tangible net worth of not less than $2.5 million and working capital of not less than $2.5 million.

On October 29, 2015, the Company entered into a second amendment to the Financing Agreement (the “Second Amendment”). Retroactive to October 1, 2015, the Second Amendment eliminated $2,500 in monthly charges for the Financing Agreement. Effective December 1, 2015, the Second Amendment reduces the effective rate of interest to 2.25% plus an amount equal to the higher of prime rate or 3.25%.
 
On July 19, 2016, the Company entered into a third amendment to the Financing Agreement. The Amendment increased the size of the revolving credit line to $2.5 million effective as of date of the amendment.
