PART I


ITEM 1.	BUSINESS

General

Echelon was incorporated in California in 1988 and reincorporated in Delaware in 1989. With its Silicon Valley based global headquarters in Santa Clara, California, and regional sales offices throughout North America, Europe, and Asia, Echelon makes its products available throughout the world.

We are a pioneer in developing distributed intelligence, open-standard control networking platforms for Industrial Internet of Things ("IIoT") applications and delivering elements necessary to design, install, monitor and control highly reliable, scalable and secure communities of devices. Echelon's vision is one of low-cost monitoring and control technology in every industrial electrical device in the world and complete vertical solutions in the fastest growing market segments. With more than ~~110~~140 million Echelon-powered devices shipped worldwide, Echelon helps its customers migrate existing legacy devices, and bring new devices and applications into a growing global Industrial Internet.

In 2014 the Internet of Things ("IoT") market opportunity became increasingly apparent. The IoT refers to a network of physical objects, each containing a unique network address, which interact with each other to share information and to take action. IoT networks can run a variety of languages, or protocols, and be connected via wired or wireless links. The IoT can be further segmented into the Human Internet of Things (HIoT) and the Industrial Internet of Things (IIoT); the latter is Echelon's market focus.

The IIoT refers to communities of rules-based, self-directed devices that reside in commercial or industrial environments and operate with little to no human interaction. Because of the harsh nature of these environments (e.g., extreme temperature, vibration, noise, humidity, dust) where connectivity can be intermittent, and because industrial applications demand high reliability, IIoT devices need to be more robust than consumer-oriented HIoT devices. Specialized requirements of the IIoT include no-compromise control capability, proven reliability, and hardened security. In addition, IIoT devices must be able to interact autonomously and function when disconnected from the Internet or a local access point. The IIoT will incorporate decades of existing and in-service infrastructure - deployed mechanical and digital vertical solutions ready to be connected. When these solutions are connected, they generally communicate with protocols developed many years ago, and often dedicated to specific applications.

Just as mainframe networking evolved to workgroup networking, which gave way to the corporate and consumer Internet, the IIoT represents a next big wave in technology. This market opportunity is driven by the convergence of control systems for lighting, HVAC, security, manufacturing, transportation, and more. The customers for IIoT products are themselves participating in highly fluid and competitive environments that prize lower costs, differentiated offerings, ~~improved~~

improved customer service, ubiquitous connectivity, and near-infinite analytic capabilities. The IIoT will unlock improvements in life quality, efficiency, safety, and more. Market analysts, such as those at IHS, Inc., project that the world market for Internet-connected devices could reach 50 billion by 2025, with the industrial segment representing the majority share of these devices.

IIoT products have long lifecycles and must operate under extreme conditions. They must also be secure to prevent unauthorized access and abuse that could cause environmental hazards or life-threatening situations. New systems running modern Information Technology protocols, such as IP, must interoperate with systems running mature Operational Technology protocols such as LONWORKS, BacNet and Modbus. Echelon’s control networking technology is purpose-built for industrial environments such as building automation, lighting and transportation.

Strategy

Today Echelon has two areas of business focus. Our ~~historic~~original product lines ~~have~~are focused on developing, marketing, selling and supporting embedded components, modules, edge servers, and ~~modules~~software that enable OEMs and other 3rd parties to quickly develop IIoT devices for their end users. Applications span a broad range of markets and products from HVAC systems to manufacturing equipment control, elevator control, transportation, and much more.

Starting in late 2014, through the acquisition of Lumewave Inc., a wireless outdoor lighting control system provider with a track record of selling its solution to U.S. municipalities, universities, medical facilities and enterprises, we began developing and introducing a connected lighting platform geared primarily for outdoor applications. Targeting the fast-growing market for LED light sources, our Lumewave by Echelon connected lighting solution supports a ~~wide~~ range of applications for smart cities and smart enterprises. These applications can reduce energy consumption, enhance citizen and employee safety, improve livability in cities and make maintenance dollars go farther.

The Lumewave by Echelon products, which include individual lighting controllers, motion sensors, ~~gateways~~edge servers, and management and maintenance software, have since been incorporated into Echelon’s product portfolio along with the established Lumewave sales channels in North America. While we continue to support our traditional, non-lighting centric customers as we always have, our primary focus is currently aimed at expanding our revenues associated with these outdoor lighting control products.

Embedded Components & Modules

Our IIoT embedded components and modules are utilized by a wide array of original equipment manufacturers (OEMs) and system integrators covering a broad spectrum of markets. Among the more significant of these markets are building automation systems, industrial and manufacturing equipment, lighting, and energy management systems. Sales levels track closely with new construction starts and tenant improvement cycles in the commercial buildings market. ~~Similarly~~Consequently, industrial and manufacturing equipment is upgraded infrequently - approximately every 10 years or so. As with other areas of the IoT, numerous technical transitions are taking place that are impacting the market and our business. Most notably, legacy systems are becoming connected to the Internet so that ‘big data analytics’ can be performed and operational systems optimized in near real time. In addition, legacy ‘operational technologies’ such as RS485, BacNet and LonWorks are ~~slowly~~ being augmented and in some cases supplanted by ~~‘Internet~~newer ~~Technologies’~~technologies such as Ethernet, Wi-Fi, Bluetooth, and TCP/IP. Standards are very much in flux which can slow the adoption of these new connectivity technologies.

In keeping with these trends, in October 2013, we introduced our IzoT™ embedded platform - purpose-built for the IIoT. The IzoT platform allows control networking to be done using Internet Protocol ("IP") all the way to the end device. IzoT software can run on any processor in an environment providing UDP/IP socket connectivity; it allows a single device to be brought to market as a LONWORKS®, BACnet®, or other protocol-supporting device; and it can be used with an underlying wired or wireless communications link, such as Ethernet, RS-485, Wi-Fi, 15.4, or Echelon’s free topology (FT) standard. The IzoT platform ~~provides~~allows acustomers ~~smooth~~to ~~migration~~easily ~~path~~embrace totheir ~~the~~current ~~emerging~~installed ~~IIoT~~solutions, ~~for~~extend ~~legacy~~those ~~devices~~solutions ~~while~~with ~~ensuring~~newer ~~compatibility~~technologies ~~with~~if ~~new~~they ~~devices~~choose, ~~connecting~~and toenhance ~~the~~both ~~same~~existing ~~network~~and new connectivity systems with cloud-based analytics. In June 2014 Echelon began sampling the IzoT platform with evaluation kits, software, chips, modules, and routers.

Both LONWORKS and the IzoT control networking platform consist of a three-tier architecture: a device tier, aan ~~control~~edge ~~node~~server tier, and an enterprise software tier. At the device tier, industrial devices such as load controllers, lighting ballasts, meters, and thermostats, embed ~~our~~Echelon or third-party free topology (FT) or power line (PL) smart transceivers, enabling them to act as peers working together to collect data and take cooperative action. These individual devices are managed by ~~control~~edge ~~nodes~~servers, insuch ~~this~~as ~~case~~ Echelon's Smart Servers. ~~When~~For aexample, ~~control~~when ~~node~~an edge server receives information from the local utility, such as a signal to shed electrical load, this information is transmitted across the twisted-pair network. The network ~~devices then execute the control signal, resulting in a reduction of energy consumption while preserving a safe and comfortable work environment.~~

Atdevices ~~the~~then ~~control~~execute ~~node tier, various control technologies and protocols are unified and supervised so that local decisions can be made at~~ the ~~device tier levels. An example of a~~ control ~~node is the Echelon SmartServer.

At the enterprise software tier, Echelon technology connects the edge server tiers to an enterprise software tier, commonly an information technology (IT) solution, so business rules can be established for the control system and operational data can be archived for later analysis. Our LONWORKS Control Network Software (LNS) is an example of an enterprise software tier product. Edge servers communicate with enterprise tier solutions using Internet protocols such as TCP/IP and web services.

Lumewave by Echelon Connected Lighting Platform

Lighting, especially outdoor lighting, has been a key application for Echelon products and has been identified as potentially being one of the fastest growing market segments in the IIoT. Street, campus and commercial outdoor lights are important assets, providing safety and aesthetic value to their community. They also consume a significant amount of electricity - as much as 40% of a city's overall electricity budget. As a result, cities, campuses and commercial enterprises are responsible for a substantial portion of worldwide energy consumption and greenhouse gas production. Therefore, these entities are looking for ways to improve infrastructure to become more environmentally friendly, increase the quality of life for their residents and occupants, and reduce costs.

Market research suggests that the transition from ‘analog’ to ‘solid state’ lighting is happening at an accelerating pace. In 2015, 19% of outdoor lights used LED light sources, which is expected to increase to 79% by 2025 according to the United States Department of Energy.

The Lumewave by Echelon connected lighting platform is a multi-application solution. The growing list of applications that Lumewave supports bring benefits in the areas of energy savings and sustainability, safety enhancement, livability and improved maintenance efficiencies. Example applications in each area include:

•

Sustainability/Energy savings. At the most basic level, Echelon's platform offers scheduling of lights on or off, the setting of dimming levels for individual or groups of lights, and intelligent lighting according to time of day, season, or weather conditions. Our systems include energy metering functions which allow a city to consider energy cost when optimizing system variables, and work with local utilities to minimize electricity charges

•

Safety. With our system lamp outages can be quickly spotted and repaired, and often predicted and repaired before they fail. Our adaptive lighting solutions can brighten lights in response to motion, direction of travel, traffic volumes and more. Our new white tuning concept allows cities to control the color of outdoor lights from soothing yellow to bright blue/white depending upon comfort and safety requirements. Our weather adaptive lighting concept adjusts schedules, brightness and color temperature based on weather conditions for optimal safety.


•	Livability. Selective dimming, adaptive lighting, white tuning and fault identification all help ensure a more livable and attractive city, which is good for business and good for the citizenry.

•

Maintenance efficiency. Our platform is fixture-agnostic so our customers are free to choose and connect virtually any light fixture from any catalog. We have both RF and powerline communication options to maximize aesthetics and performance. The platform allows for GPS options, automated topology optimization, and includes a powerful Central Management System (CMS) configuration and management features to make startup commissioning and management easy. Powerful reporting helps optimize and predict maintenance needs, monitor energy consumption and identify communication problems. Separate ‘application widgets’ support the needs of the specific applications described above.

Echelon’s outdoor lighting control product portfolio includes:

• Smart Transceivers: Outdoor lighting manufacturers can embed our power line smart transceivers into their outdoor light ballasts, drivers, and generators; or can use these transceivers to develop outdoor lighting controllers that serve as add-on products for existing dimmable ballasts and drivers within a luminaire. These components ~~enable command, control, and monitoring of each light. They communicate with the Echelon SmartServer segment controller over existing power lines.~~

Go-To-Market (Sales) Strategy

We sell our IIoT platform to OEMs in the building, lighting, and industrial controls markets directly and through distribution worldwide. These efforts are supported with application engineering, technical support, and industry experts working inout of the U.S. as well as China, Japan, South Korea, India, the Netherlands, and the United Kingdom. In outdoor lighting, in addition to selling our platform to lighting OEMs worldwide, in some geographies, we also offer the complete Lumewave by Echelon platform solution to end customers such as municipalities, cities, campuses and commercial enterprises through local system integration partners and channel representatives.

Echelon organizes its sales resources by region. Within a region, sales personnel selling our embedded solutions work directly with large OEM customers such as Honeywell, Schneider, Siemens, ~~Philips,~~ Trane, and others. Sales personnel focused on our lighting platform work with distribution partners, regional manufacturers’ representatives, and regional system integrators. We will often "sell with" these partners by calling on end users such as municipalities and enterprises at their side.

Product Development

Our future success depends in large part on our ability to enhance existing products, reduce product cost, and develop new products that offer technological competitiveness. We have made and intend to continue to make substantial investments in product development, while implementing strategies for overall product development cost reduction where appropriate.

Our strategy is to focus our product innovation efforts on enabling a platform that is versatile and capable of deployment in embedded and connected lighting markets. The platform is comprised of 3 ~~layers~~tiers:

•The enterprise management and cloud ~~layer~~tier,

•The ~~gateway~~edge ~~and~~server ~~router layer~~tier,

•and the ~~devices~~device ~~layer~~tier.

The platform is extensible to incorporate different types of end devices, protocols, services and business logic to drive sustainability/energy savings, enhance safety, increase efficiency, and manage livability. Key to the extensibility lies in the ability to incorporate selected new functionality and partner products. As an example, our recent proof of concept quickly incorporated weather data from the IBM Watson IoT platform and enabled us to study the balance of managing sustainability while enhancing safety for residents in a city. Also key to the extensibility lies in the ability to standardize at the appropriate layers, with hardware, operating systems, web capabilities, different physical and network protocols, new IoT messaging systems (like MqTT), data driven functionality, etc. Another key part of our product development strategy is balancing standardization with innovation, to optimize functionality, and intellectual property. As we build out this platform, we will aggressively file the appropriate patent disclosures to protect our innovation and intellectual property.

Our total expenses for product development were $8.3 million for 2016, $9.7 million for 2015, and $9.5 million for

~~2014~~Our total expenses for product development were $9.3 million for 2017, and $8.3 million for 2016. Included in these totals were stock-based compensation expenses of $~~173~~475,000, ~~$304,000,~~ and $~~(73~~173,000), for the years ended December 31, ~~2016~~2017, ~~2015,~~ and ~~2014~~2016, respectively.

To date, we have not capitalized any software development costs from our development efforts.

Marketing

Our marketing efforts focus on two key elements: awareness and demand generation/sales enablement. From an awareness perspective, we seek to generate visibility and credibility of our brand, the products and solutions that we offer, and the capabilities and benefits that they bring. Our marketing program comprises press releases, advertising, collateral, published technical and thought-leadership papers, newsletters, and customer case studies describing the benefits our customers are seeing from implementing our solutions. We also participate in industry events and trade shows, speak at relevant industry conferences, and are continually enhancing our global websites.

Marketing also focuses on making it easier for our sales teams and our partners to sell our solutions. We do this through a variety of demand generation and sales enablement activities such as webinars/seminars, lead-generation from our participation at industry exhibitions and conferences, and the production of focused selling tools such as sales playbooks, competitive analyses, and sales presentations and training. We also actively participate in LONMARK® International, an association directly focused on the adoption of our products.

We focus our sales teams using a systematic pipeline management process, whereby prospects are identified, qualified, and tracked, with the expectation that a portion of these opportunities are ultimately closed.

Principal Customers

During the ~~three~~ years ended December 31, 2017 and 2016, we had ~~two~~one ~~customers~~customer that accounted for a significant portion of our revenues: Avnet Europe Comm VA (“Avnet”), the primary distributor of our IIoT products in Europe, and ~~Enel Distribuzione Spa ("Enel"), an Italian utility company~~Japan.

To maintain and improve our competitive position, we must keep pace with the evolving needs of our customers and continue to develop and introduce new products, features, and services in a timely and efficient manner. The principal competitive factors that affect the markets for our products include:


•	the price and features of our products such as adaptability, scalability, functionality, ease of use, and the ability to integrate with other products;


•	our ability to anticipate changes in customer requirements and to develop new or improved products that meet these requirements in a timely manner;


•	our product reputation, quality, performance, and conformance with established industry standards;


•	our customer service and support;


•	warranties, indemnities, and other contractual terms; and


•	customer relationships and market awareness.

Additionally, while our product implementations are proprietary to Echelon and are often protected by unique, patented processes, key technologies such as LONWORKS and IzoT are open, meaning that many of our basic control networking patents are broadly licensed without royalties or license fees. For instance, all of the network management commands required to develop software that competes with our LNS software are published. As a result, our customers are capable of developing hardware and software solutions that compete with many of our products.

Government Regulation

Many of our products and the markets and industries in which they are used are subject to U.S. and foreign regulation as well as local, industry-specific codes and requirements. For example, the power line medium, which is the communications medium used by some of our products, is subject to special regulations in North America, Europe, and Japan. In general, these regulations limit the ability of companies to use power lines as a communication medium. In addition, some of our competitors have attempted to use regulatory actions to reduce the market opportunity for our products or to increase the market opportunity for their own products. We have resisted these efforts and will continue to oppose competitors' efforts to use regulation to impede competition in the markets for our products. Our business might also be affected by other regulatory factors, including public utility commission or similar approvals and government mandates. This could lead to an extension of the sales cycle or even cancellation of a customer's order.

In addition, the market for our products might experience a movement toward standards-based protocols driven by governmental action. To the extent that we do not adopt such protocols or do not succeed in achieving adoption of other protocols we use as standards or de facto standards, sales of our products might be adversely affected. The adoption of voluntary standards or the passage of governmental regulations that are incompatible with our products or technology could limit the market opportunity for our products, which could harm our revenues, results of operations, and financial condition.

Proprietary Rights

We own registered patents in the United States and in selected foreign countries. Many of the specific patents that are fundamental to LONWORKS technology have been licensed to our customers with no license fee or royalties.

We also hold several trademarks in the United States and select foreign countries, many of which are registered, including Echelon, Lumewave by Echelon, LumInsight, LonBuilder, LonTalk, LONWORKS, Neuron, LON, LonPoint, LonMaker, IzoT, LNS, LonManager, Digital Home, and NodeBuilder.

Employees

As of February 28, ~~2017~~2018, we had 8174 employees worldwide. About 5049 employees are located at our headquarters in California and 1612 employees are located in other offices throughout the United States. Our remaining employees are located in five countries worldwide, with the largest concentrations in China, Hong Kong, the Netherlands, and the United Kingdom. None of our employees are represented by a labor union. We have not experienced any work stoppages and we believe relations with our employees are good.

ITEM 1A. RISK FACTORS

Investing in our common stock involves a high degree of risk. Interested persons should carefully consider the risks described below in evaluating our company. Additional risks and uncertainties not presently known to us, or that we currently consider immaterial, may also impair our business operations. If any of the following risks actually occur, our business, financial condition or results of operations could be materially adversely affected. In that case, the trading price of our common stock ~~would~~could ~~likely~~ decline. Before deciding to purchase, hold or sell our common stock, you should carefully consider the risks described in this section. This section should be read in conjunction with the condensed consolidated financial statements and accompanying notes thereto, and Management’s Discussion and Analysis of Financial Condition and Results of Operations, both of which are included in this Annual Report on Form 10-K.

There can be no guarantee that the IIoT market in general, and the lighting market segment in particular, will develop as expected, or that we will be successful in pursuing these market opportunities.

We have devoted and will continue to devote significant effort and resources to leverage our technology and develop and launch our platform to customers within the IIoT market. However, to date, the market for our products has not developed as quickly as anticipated, and our efforts to capitalize on these opportunities have not produced the results we anticipated. Our efforts to capitalize on these opportunities may not be successful in the near term, or at all. ~~Furthermore, for the last several years, revenues from our legacy embedded systems products have been declining, and we anticipate that this trend will continue for the foreseeable future.~~

Although revenues from our legacy embedded systems products have been increasing in recent quarters, prior to 2017 they had been declining annually for several years. We cannot guarantee that the recent improvement in sales of these products will continue.

We have decided to focus ~~predominantly~~heavily on lighting controls within the IIoT as our targeted market. As we have a limited operating history in this market segment, we are subject to a number of risks and uncertainties that may impact our ability to gain market acceptance for our lighting control products.

In recent years, we have invested substantial resources in the development and commercialization of control networking solutions for the lighting market. However, we have a limited operating history in this market segment, and we may not recognize a meaningful amount of revenues from these efforts in the near future, or at all. Our efforts to gain market acceptance for our lighting control products and solutions are subject to considerable risk and uncertainty, including:


•	the risk of competition and emerging technologies (see “If we do not develop and maintain adequate distribution channels, our revenues will be harmed” for additional information on the risks associated with competing for market share);


•	the risk that we will not be able to develop adequate sales channels for these new products and services (see “Our IIoT revenues may not meet expectations, which could cause volatility in the price of our stock” for additional information on the risks associated with establishing new sales channels);


•	the risk that we misjudge the market and fail to develop solutions that meet the requirements of our existing or potential customers;

• the risk that our solutions will suffer security breaches or ~~unintended~~otherwise ~~releases~~allow ofunauthorized ~~private~~access to, or acquisition of, data;

• the risk that our products will not perform adequately due to defect or misuse by customers (see “Liabilities resulting from defects in or misuse of our products, whether or not covered by insurance, may delay our revenues and increase our liabilities and expenses” for additional information on the risks associated with defective or misused products); and

•

the risk that our supply chain for components is unable to meet our demand (see “Because we depend on a limited number of key suppliers and in certain cases, a sole supplier, the failure of any key supplier to produce timely and compliant products could result in a failure to ship products, or could subject us to higher prices, which would harm our results of operations and financial position” for additional information on the risks associated with manufacturing).

We have changed our business model significantly in recent years, which makes it difficult to evaluate our prospects and forecast our future ~~operating~~ results of operations.

Although we commenced our business in 1988, we have made significant changes to our business model in recent years. Historically, we derived all of our revenues from our embedded systems and Grid businesses. However, in 2014, we sold our Grid business, and ~~over~~prior ~~the~~to ~~last several years~~2017, we ~~have~~had ~~experienced~~been experiencing a decline in revenues from our legacy embedded systems products and services~~. In addition~~, weincluding ~~expect~~a tocessation ~~see further reductions~~ in our shipments to Enel.

In recent years, we have shifted our focus to networking solutions for the outdoor lighting market. Unlike our legacy embedded systems products, which are typically sold to OEMs for incorporation into their products, which are then sold to their commercial and industrial customers, our lighting solutions products are more project based, being sold through energy services companies and distributors to municipalities, enterprise and educational campuses, retailers, and other end users. In addition, our outdoor lighting solutions typically generate lower overall gross margins than do our embedded systems products.

As we have a limited operating history with our lighting solutions, our ability to evaluate our current business and forecast our future ~~operating~~ results of operations and effectively assess our future prospects is subject to a number of uncertainties that may impact our ability to plan for and model future growth. Our historical revenue growth should not be considered indicative of our future performance and such growth may stagnate or decline over time. Further, in future periods, our revenues could decline for a number of reasons, including the failure to offset the expected decline in revenues from our embedded systems products by an increase in sales of our lighting solutions, changes in our pricing structure, increased competition in the IIoT market generally or in the lighting market in particular, or our failure, for any reason, to capitalize on growth opportunities. We have encountered and will continue to encounter risks and uncertainties frequently experienced by companies in rapidly changing industries. If our assumptions regarding these risks and uncertainties, which we use to plan our business, are incorrect or change, or if we do not address these risks successfully, our operating and financial results could differ materially from our expectations, and our business could suffer.

Our revenues may not meet expectations, and our operating expenses may be higher than we anticipate, which could cause volatility in the price of our stock.

As we attempt to grow our IIoT business, we ~~will~~expect to commit significant resources developing new products in emerging markets. In addition, our IIoT business operates in nascent markets, such as outdoor lighting and controls, in which we have yet to build a reliable customer base. As a result, sales of our products are unpredictable and yet to be proven, and sales and marketing costs related to our products may be significant. These factors could have a negative impact on our revenues and make it difficult to project our financial results, which could cause declines and volatility in our stock price. Additionally, because we are operating

in an emerging market, risks that we are not currently able to identify are likely to materialize and could negatively impact our operations and financial condition.

Emerging markets are particularly dynamic and highly competitive, and we may lose sales to our competitors, which would harm our revenues and results of operations.

Competition in the IIoT market is intense and involves rapidly changing technologies, evolving industry standards, frequent new product introductions, industry consolidations, effective management of distribution channels, rapid changes in customer or regulatory requirements, and localized market requirements. In each of our existing and target markets, we compete with a wide array of manufacturers, vendors, strategic alliances, systems developers and other businesses. The future of our IIoT business depends significantly on our ability to react to changing customer needs by enhancing our existing products and developing new products. There can be no guarantee, however, that new products and product enhancements will be accepted by businesses and consumers. If we make investments in technologies that do not gain market acceptance, our business may not grow as anticipated. In addition, future product offerings by our competitors can render our products obsolete. Any failure to evolve with emerging technologies and our competitors could cause a loss of market share and result in declining revenues.

The principal competitive factors that affect the markets for our products include the following:


•	our ability to anticipate changes in customer or regulatory requirements and to develop, or improve, our products to meet these requirements in a timely manner;


•	the price and features of our products such as adaptability, scalability, functionality, ease of use, and the ability to integrate with other products;


•	our product reputation, quality, performance, and conformance with established industry standards;


•	our ability to expand our product line to address our customers’ requirements;


•	our ability to effectively manage and expand our distribution channels to address new markets for current and future products;


•	our ability to meet a customer’s required delivery schedules;


•	a customer’s willingness to do business with us because of our size and perceived concerns regarding our liquidity and financial strength relative to our competitors;


•	the risk of industry consolidation, which is particularly high in emerging markets such as the IIoT;


•	our customer service and support;


•	warranties, indemnities, and other contractual terms; and


•	customer relationships and market awareness.

Competitors for our IIoT products include some of the largest companies in the electronics industry, operating either alone or together with trade associations and partners. Key company competitors include companies such as Cimcon Lighting, Inc., Cree Inc., Digi International, General Electric, LED Roadway Lighting, Maxim Integrated Products, Philips, Siemens, Silver Spring Networks, STMicroelectronics, Telensa, Texas Instruments, and Tridium. Key industry standard and trade group competitors include BACnet, DALI, DeviceNet, HART, Konnex, Profibus, ZigBee, and the ZWave Alliance in the IIoT market. Each of these standards and/or alliances is backed by one or more competitors. For example, the ZigBee alliance includes over 300 member companies with promoter members, such as Ember, Emerson, Freescale, Kroger, Landis+Gyr (a subsidiary of Toshiba), Philips, Reliant Energy, Schneider Electric, STMicroelectronics, Tendril, and Texas Instruments. Additionally, because we are operating in an emerging market, it is likely that additional competitors could surface and rapidly gain market share.

Many of our competitors, alone or together with their trade associations and partners, have significantly greater financial, technical, marketing, service and other resources, significantly greater name recognition, and broader product offerings, all of which may impact the willingness of customers and potential customers to do business with us. Our future success will depend on our ability to enhance our existing products, to introduce new products to meet changing customer requirements and emerging technologies, and to demonstrate the performance advantages and cost-effectiveness of our products over competing products. If we are unable to do so and thus are unable to compete effectively in any of the markets we serve, our revenues, results of operations, and financial position would be harmed.

~~For~~• ~~our outdoor lighting controls products,~~ the ~~sales~~mix ~~cycle can also be extended.

In• ~~addition~~shipment, ~~potential~~payment ~~customers for our products~~schedules, ~~both embedded systems~~ and ~~outdoor~~product ~~lighting~~acceptance controls, include local, state and federal government authorities. For several reasons, sales to government authorities can be extended and unpredictable. Government authorities generally have complex budgeting, purchasing, and regulatory processes that govern their capital spending, and their spending is likely to be adversely impacted by economic conditions. In addition, in many instances, sales to government authorities may ~~require field trials and may~~ be delayed by the time it takes for government officials to evaluate multiple competing bids, negotiate terms, and award contracts. We further face the risk of cancellation during development and production due to regulatory, government and geopolitical changes, and delays in installing, operating, and evaluating the results of any field trials before full implementation of our products.;

~~For~~• ~~these reasons, the sales cycle associated with~~ our ~~IIoT~~ products ismay ~~subject to a number of significant risks that are beyond our control.

•	our ability to develop products that comply with future regulations and trade association guidelines;


•	the revenue recognition rules relating to certain of our products could require us to defer some or all of the revenue associated with product shipments until certain conditions, such as delivery and acceptance criteria for our software and/or hardware products, are met in a future period;


•	our CEMs may not be able to provide quality products on a timely basis, especially during periods where capacity in the CEM market is limited;


•	our products may not be manufactured in accordance with specifications or our established quality standards, or may not perform as designed;


•	downturns in any customer’s or potential customer’s business, or declines in general economic conditions, could cause significant reductions in capital spending, thereby reducing the levels of orders from our customers;


•	we may incur costs associated with any future business acquisitions; and


•	any future impairment charges related to our intangible assets that are required to be recorded under generally accepted accounting principles in the United States may negatively affect our earnings and financial condition.

Any of the above factors could, individually or in the aggregate, have a material adverse effect on our results of operations and our financial condition, which could cause our stock price to decline

If we are not able to develop or enhance our products in a timely manner, our revenues will suffer.

Due to the nature of development efforts in general, we can experience delays in the introduction of new or improved products beyond our original projected shipping date for such products. Historically, when these delays have occurred, we experienced an increase in our development costs and a delay in our ability to generate revenues from these new products. In addition, such delays could cause us to incur penalties if our deliveries are delayed, could otherwise impair our relationship with any of our customers that were relying on the timely delivery of our products in order to complete their own products or projects, or could cause the customer to cancel orders or to seek alternate sources of supply or other remedies. Any delay in the introduction of new products could impact future revenue targets or forecasts.

We are sometimes required to modify our products to meet local rules and regulations. WeGiven the competitive nature of these markets, we may not be able to increase the price of such products to reflect the costs of such modifications~~, given competitive markets~~. In addition, given the long-term nature of development activities, we may be required to undertake such modifications prior to receiving firm commitments or orders from our customers. In either of these or other similar scenarios, we may not be able to recover our costs attributable to required product modifications.

The market for our products is new and unproven, and we cannot rely solely on our existing distributors to sell our products. Therefore, we are focused on expanding our distribution channel to include new distributors in order to generate revenue from product sales~~. We~~ ~~expect~~cycle ~~that the distribution channel~~ for our products ~~will be dispersed and it~~ is ~~difficult~~often tolengthy ~~predict how long it will take~~ and ~~how costly it will be to develop~~unpredictable. We may not be successful in developing and maintaining adequate distribution channels within our expected timeframe and cost expectations, if at all. In addition, if any of our new or existing distributor partners fail to dedicate sufficient resources to market and sell our products, our revenues would suffer. Furthermore, if our existing distributor partners were to significantly reduce their inventory levels for our products, we could expect a decrease in service levels to our end-use customers.

The sales cycle between initial customer contact and execution of a contract or license agreement with a customer or purchaser of our products can vary widely. Initially, we must educate our customers about the potential applications of and cost savings associated with our products.

If we are successful in this effort for our embedded systems products, OEMs will typically conduct extensive and lengthy product evaluations before making a decision to design our products into their offerings. Once the OEM decides to incorporate our products, volume purchases of our products are generally delayed until the OEM’s product development, system integration, and product introduction periods have been completed. In addition, changes in our customers’ budgets, or the priority they assign to control network development, could also affect the sales cycle.

For our outdoor lighting controls products, the sales cycle can also be extended. As a nascent market, many of our sales channel partners, as well as end use customers, are not aware of the benefits our controls technology can bring to their lighting systems. This requires extensive educational efforts on our part and these efforts may not be successful or meet our objectives. Even with the benefit of this eduction, when dealing with larger projects such as to municipalities, the post-education sales cycle typically commences with a trial deployment of relatively low value to us. If the trial is successful, the end use customer may commence a full scale deployment that could take months or years to complete, if at all.

In addition, potential customers for our products, both embedded systems and outdoor lighting controls, include local, state and federal government authorities. Sales to government authorities can be extended and unpredictable. Government authorities generally have complex budgeting, purchasing, and regulatory processes that govern their capital spending, and their spending is likely to be adversely impacted by economic conditions. In addition, in many instances, sales to government authorities may require field trials and may be delayed by the time it takes for government officials to evaluate multiple competing bids, negotiate terms, and award contracts. We further face the risk of cancellation during development and production due to regulatory, government and geopolitical changes, and delays in installing, operating, and evaluating the results of any field trials before full implementation of our products.

For these reasons, the sales cycle associated with our IIoT products is subject to a number of significant risks that are beyond our control. Consequently, if our forecasted customer orders are not realized, or are delayed, our revenues and results of operations could be materially and adversely affected. In addition, an extended sales cycle may result in our inability to recognize revenue from existing or new projects until the end of several fiscal quarters. This may also make it difficult to predict our financial results and increase the volatility of our stock price.

If we do not develop and maintain adequate distribution channels, our revenues will be harmed.

The market for our products is new and unproven, and we cannot rely solely on our existing distributors to sell our products. Therefore, we are focused on expanding our distribution channel to include new distributors in order to generate revenue from product sales. We expect that the distribution channel for our products will be dispersed and it is difficult to predict how long it will take and how costly it will be to develop.

Furthermore, if our existing distributor partners were to significantly reduce their inventory levels for our products, we could expect a decrease in service levels to our end-use customers.

Sales of our products may fail to meet our financial targets, which would negatively impact our results of operations and expected return on investment in the IIoT market.

We have invested and intend to continue to invest significant resources in the development and sales of products in the emerging IIoT market, particularly in the outdoor lighting market segment. If we are unable to receive orders for, ship, and recognize revenue for our products in a timely manner, and in the quantities and at prices in line with our targets, our financial results will be harmed. Our long-term financial goals include expectations for a return on these investments, but we may or may not ever realize any return whatsoever on this investment of resources.

Prior to 2017, annual revenues generated from our embedded systems business failed to meet our expectations. If this revenue decline were to return, our ability to continue funding our entry into the outdoor lighting segment could be harmed.

In order to achieve our financial targets, we believe that we must meet the following objectives:

• ~~Achieve~~achieve acceptance of our products in the IIoT market, particularly the outdoor lighting market, in order to increase our revenues;

• ~~Manage~~manage our operating expenses to a reasonable percentage of revenues; and

• ~~Manage~~manage our cash resources prudently.

Even if we meet these objectives, there can be no assurance that we will meet our overall financial targets and objectives.

A significant portion of our operating expenses are fixed. Therefore, if we cannot achieve our revenue targets, our use of cash balances would increase, our losses would increase, and/or we would be required to take additional actions necessary to reduce expenses. We cannot assure you that we will meet any or all of these objectives to the extent necessary to achieve our financial goals and, if we fail to achieve our goals, our results of operations are likely to be harmed.

In our legacy embedded systems business, we may be unable to promote and expand acceptance of our open, interoperable control systems over competing protocols, standards, or technologies.

LONWORKS and IzoT technology are open, meaning that many of our technology patents are broadly licensed without royalties or license fees. As a result, our IIoT customers are able to develop hardware and software solutions that compete with some of our products. Because some of our customers are OEMs that develop and market their own control systems, these customers, in particular, could develop competing products based on our open technology. For instance, we have published all of the network management commands required to develop software that competes with our LNS software.

In addition, many of our IIoT competitors are dedicated to promoting closed or proprietary systems, technologies, software and network protocols or product standards that differ from or are incompatible with ours. We also face strong competition from large trade associations that promote alternative technologies and standards for particular vertical applications or for use in specific countries. These include BACnet, DALI, and KNX in the buildings market; DeviceNet, HART, and ProfiBus in the industrial controls market; TCN in the rail transportation market; and Echonet, ZigBee, and Z-Wave in the home control markets.

The ability of our IIoT products to interoperate with multiple standards is important to our success. Our technologies, protocols, or standards may not be successful or we may decide not to invest our resources at the levels required in order to compete with new or enhanced products or standards introduced by our IIoT product line competitors, which would have a material adverse effect on our revenues, results of operations, and financial condition.

We are increasingly dependent on third-party developers.

We are increasingly reliant on various third parties for the development of software used in our products. There is a risk that the software provided by these third parties could contain errors or defects that could adversely impact the quality of our products. In addition, these third parties may use open source or other code that contains security flaws, which may cause our products to be more prone to hacking or other security ~~attacks~~incidents. We may also be negatively impacted by employee turnover or other challenges that these third-party developers face in their own businesses. Third parties may also choose not to develop software for our products if we do not have adequate market share or sufficient perception of future success. The materialization of any of these risks would impact our ability to deliver quality products on a timely basis, which could adversely impact our reputation and brand and harm our business and ~~operating~~ results. of operations.

In addition, many of these third-party developers are located in markets that are subject to political risk, intellectual property misappropriation, corruption, infrastructure problems and natural disasters, in addition to country specific privacy and data security risks, given current legal and regulatory environments. The failure of these third parties to meet their obligations and adequately deploy business continuity plans in the event of a crisis and/or the development of significant disagreements, natural or man-made disasters or other factors that materially disrupt our ongoing relationship with these developers could negatively affect our operations.

Because we depend on a limited number of key suppliers and, in certain cases, a sole supplier, the failure of any key supplier to produce timely and compliant products could result in a failure to ship products, or could subject us to higher prices, which would harm our results of operations and financial position.

Our future success will depend significantly on our ability to timely manufacture our products cost effectively, in sufficient volumes, and in accordance with quality standards. For most of our products requiring assembly, we rely on a limited number of contract electronic manufacturers (CEMs), principally Bel-Fuse. These CEMs procure material and assemble, test, and inspect the final products to our specifications. This strategy involves certain risks, including reduced control over quality, costs, delivery schedules, availability of materials, components, finished products, and manufacturing yields. For example, an extended delay in the supply of a key component could disrupt the manufacturing of our products. Any such interruption in the supply of key components could therefore have a material adverse effect on our customer relationships and revenues. As a result of these and other risks, our CEMs could demand price increases for manufacturing our products. The Bel-Fuse factories, where our products are manufactured, are located in China. The Chinese government maintains programs, whereby labor rates for the manufacture of our products will increase over time. In addition, our agreements with our CEMs make us responsible for components and subassemblies purchased by the CEMs when based on our forecasts or purchase orders. Accordingly, we will be at risk for any excess and obsolete inventory purchased by our CEMs. Lastly, CEMs can experience turnover, instability, and lapses in manufacturing or component quality, exposing us to additional risks as well as missed commitments to our customers.

excess and obsolete inventory purchased by our CEMs. Lastly, CEMs can experience turnover, instability, and lapses in manufacturing or component quality, exposing us to additional risks as well as missed commitments to our customers.

We also maintain manufacturing agreements with a limited number of semiconductor manufacturers for the production of key products. Cypress Semiconductor is the sole licensee, manufacturer and distributor for the Cypress Neuron, which is an important part of the LONWORKS portfolio. As a result, we or our customers may experience longer lead times and higher pricing for these parts, which could result in reduced orders for our products from these same customers. In addition, Cypress Semiconductor could decide to reduce or cease production of the Neuron chip in the future, at any time, with or without advance notice to us.

The FT 5000 free topology transceiver and the Neuron 5000 are sole sourced from the Taiwan Semiconductor Manufacturing Company (TSMC) foundry through our aggregator Open Silicon. In addition, we currently purchase several key products and components from sole or limited source suppliers with which we do not maintain signed agreements that would obligate them to supply to us on negotiated terms. Any sole source relationship could make us vulnerable to price increases, particularly where we do not maintain long-term supply agreements with the supplier, or to supply disruptions that would result if the supplier issued an end of life notice with respect to a key product.

We are continuing to review the impact that economic factors are having on our suppliers. Some of these suppliers are large, well-capitalized companies, while others are smaller and more highly leveraged. In order to mitigate these risks, we may take actions such as increasing our inventory levels and/or adding additional sources of supply. Such actions may increase our costs and increase the risk of excess and obsolete inventories. Even if we undertake such actions, there can be no assurance that we will be able to prevent any disruption in the supply of goods and services we receive from these suppliers.

We may also elect to change any of these key suppliers. As part of such a transition, we may be required to purchase certain raw material and in-process inventory from the existing supplier and resell it to the new source. In addition, if any of our key suppliers were to stop manufacturing our products or supplying us with our key components, it could be expensive and time consuming to find a replacement. Also, as our business grows, we will be required to expand our business with our key suppliers or find additional sources of supply. There is no guarantee that we would be able to find acceptable alternative or additional sources. Additional risks that we face if we must transition between CEMs include:

or find additional sources of supply. There is no guarantee that we would be able to find acceptable alternative or additional sources. Additional risks that we face if we must transition between CEMs include:


•	moving raw material, in-process inventory, and capital equipment between locations, some of which may be in different parts of the world;


•	reestablishing acceptable manufacturing processes with a new work force; and


•	exposure to excess or obsolete inventory held by contract manufacturers for use in our products.

The failure of any key manufacturer to produce a sufficient number of products on time, at agreed quality levels, and fully compliant with our product, assembly and test specifications could result in our failure to ship products in a timely manner or at all, which would adversely affect our revenues and gross profit, and could result in claims against us by our customers, which could harm our results of operations and financial position. Any such failures could also have a negative impact on our ability to project our financial results, which could result in volatility in our stock price.

~~Our~~Because ~~business~~our ~~depends~~products onuse ~~the~~components ~~Internet~~or ~~and~~materials ~~its~~that ~~continued~~may ~~access~~be subject to price fluctuations, shortages, interruptions of supply, or discontinuation, we may be unable to ship our products in a timely fashion, which would adversely affect our revenues, harm our reputation, and ~~development~~negatively impact our results of operations.

We may be vulnerable to price increases for products, components, or materials, such as silver, copper, and cobalt. We generally do not enter into forward contracts or other methods of hedging against supply risk for these items. In addition, we have in the past and may in the future experience shortages or interruptions in supply for certain of these items, including products or components that have been or will be discontinued, which can cause us to delay shipments beyond targeted or announced dates. We have also reduced our inventory levels from historical levels, which could impact our ability to supply our customers with products in a timely manner if there was an unexpected increase in demand. Such shortages or interruptions could result from events outside our control, as was the case with the earthquake and tsunami in Japan in March 2011. To help address these issues, we may decide from time to time to purchase quantities of these items that are in excess of our estimated requirements. As a result, we could be forced to increase our excess and obsolete inventory reserves to provide for these excess quantities, which could harm our results of operations. In addition, if a component or other product goes out of production, we may be required to requalify substitute components or products, or even redesign our products to incorporate an alternative component or product.

If we experience any shortage of products or components of acceptable quality, or any interruption in the supply of these products or components, or if we are not able to procure them from alternate sources at acceptable prices and within a reasonable

period of time, our revenues, gross profits or both could decrease. In addition, under the terms of some of our contracts with our customers, we may also be subject to penalties if we fail to deliver our products on time.

Our business depends on the Internet and its continued and unimpeded access and development.

The Internet is crucial to the operations of many of our IIoT products and is a key component of the IIoT market as a whole. Our reliance on the Internet exposes us to a number of risks and uncertainties that are beyond our control, including risks related to privacy and data security. It is difficult to quantify the impact that any future security or performance problems associated with the Internet may have on our products and revenues.

In addition, state, federal and foreign regulators could adopt laws and regulations that impose additional burdens on companies that conduct business over the Internet. The growth and development of the market for online services may prompt calls for more stringent consumer protection laws or laws that may inhibit the use of Internet-based communications or the information contained in these communications. The adoption of any additional laws or regulations may impact the growth of the IIoT market. Any new legislation or regulations, application of laws and regulations from jurisdictions whose laws do not currently apply to our business, or application of existing laws and regulations to the IIoT and other related services could increase our costs and harm our growth. In particular, there is increasing focus on privacy and data security regulations applicable to the IoT. For example, the Federal Trade Commission released a report on January 27, 2015 with recommendations for privacy and data security recommendations applicable to connected devices, objects and sensors. In addition, the EU intends to adopt new, stricter standards around privacy and data security. We may be required to re-engineer our products and incur additional costs to comply with new regulations, any of which would negatively impact our business.

In particular, there is increasing focus on privacy and data security laws and regulations applicable to the IoT. A wide variety of provincial, state, national, and international laws and regulations apply to the collection, use, retention, protection, disclosure, transfer and other processing of personal data. Regulatory authorities have increased their privacy- and data security-related activity in the IoT domain in recent years. For example, the Federal Trade Commission released a report on January 27, 2015 with recommendations for privacy and data security applicable to connected devices, objects and sensors.We also may become obligated to comply with, or may choose to comply with, self-regulatory or other requirements applicable to privacy or data security.

The privacy- and data security-related laws and regulations that may apply to us are evolving and subject to differing interpretation and enforcement, and may result in ever-increasing regulatory and public scrutiny and escalating levels of enforcement and sanctions. For example, the European Union General Data Protection Regulation, which becomes fully effective in May 2018, imposes more stringent data protection requirements and provides for greater penalties for noncompliance. Our actual or perceived failure to comply with applicable laws and regulations or other actual or alleged obligations relating to privacy or data security, or to protect personal data, could result in regulatory investigations or regulatory enforcement actions and remedies against us, including fines, imprisonment of company officials and public censure, private litigations, claims for damages, damage to our reputation and loss of goodwill (both in relation to existing end use customers and prospective end use customers), any of which could have a material adverse effect on our operations, financial performance, and business.

If our IIoT solutions become subject to cyber-attacks, or if public perception is that they are vulnerable to cyber-attacks, our reputation and business would suffer.

We have designed our IIoT products, including our outdoor lighting solutions products, to interoperate with other third-party products and systems. Although we attempt to safeguard our products and solutions from cybersecurity threats, the potential for cyber security attacks and other incidents continues to evolve in scope and frequency.

Advances in and expanding availability of technical tools to enable cybersecurity attacks, and increasing sophistication of the threats, deepen the risk of potential security ~~failures~~incidents. This risk expands as new protocols and devices are implemented into our products and systems, and as customer requirements evolve. Should our products, or the combination of our products into third party systems, fail to prevent or be unable to withstand any such threats or cyber-attacks, or if our partners or customers fail to safeguard ~~the~~applicable technologies, products or the systems with adequate security policies and measures or otherwise, our business and reputation may be harmed.

We have attempted to design certain of our products to prevent and monitor unauthorized access, misuse, modification or other activities related to those products and the systems into which the products are intended to be placed. Despite our security measures, our products or systems may be subject to unauthorized break ins, viruses, disruptions, high-jacking, cyber terrorism, misuse, ortampering, other unauthorized ~~tampering~~access or modification, or unauthorized access to, or acquisition, loss, or alteration of, data. Should our products fail to perform, or be unable to withstand a cyber-attack, or otherwise suffer a security incident, or be perceived to have suffered any kind of security vulnerability or cyber incidents, we could face legal liability, and encounter material adverse financial and reputational harm.

In addition, we believe that there could be incidents of security breaches in the future which could receive a high degree of publicity and visibility, regardless of whether or not the problem is due or related to the performance of our particular products or systems. Any such publicity could have a negative effect on public confidence, or cause a perception that our solutions are or could be subject to similar attacks or breaches, and our business, operating results and financial condition may be materially adversely affected. Such an event could also result in a material adverse effect on the market price of our common stock, independent of the direct effects on our business.17

16In addition, we believe that there could be incidents of security breaches in the future which could receive significant publicity and visibility. Any such publicity or visibility, regardless of whether the problem is due or related to the performance or security measures of our products or systems, could have a negative effect on public confidence, or cause a perception that our solutions are or could be subject to similar attacks or breaches, and our business, results of operations and financial condition may be materially and adversely affected. Such an event could also result in a material adverse effect on the market price of our common stock, independent of the direct effects on our business.

We are dependent on technology systems and third-party content that are beyond our control.

Our success in the IIoT market will depend in part on the availability of online services and Internet connections to facilitate data transmission. In most instances, these services will be provided by third parties and will be outside of our control. Even when we are not responsible for connectivity or other problems, users of our products may attribute the problem to us. For example, many of our customers rely on the capacity, reliability and security of wireless networks owned and controlled by third parties to use our IIoT products. However, the price of access and operational integrity of online services, wireless networks and Internet connections are beyond our control. As a result, it may be difficult to identify the source of problems if they occur. This could diminish our brand and harm our business, divert the attention of our technical personnel from our product development efforts or cause significant customer relations problems.

Information Technology system security failures, cyber-attacks, and other technological breaches could cause harms to our business.

We also rely on the security of our third party providers to protect our proprietary information and information of our customers. Information technology system failures, including a breach of our or our third party providers’ data security, could disrupt our ability to function in the normal course of business by potentially causing, among other things, an unintentional disclosure of customer information. Despite our implementation of security measures or those of our third party providers, information systems may be vulnerable to threats such as computer hacking, cyber-terrorism or other unauthorized attempts by third parties to access, modify or delete our or our customers’ data or otherwise disrupt our systems. Any such breach could have a material adverse effect on our business, ~~operating~~ results of operations, and our reputation as a provider of data collection, and secure and reliable device connection, collaboration and communications solutions, including legal claims for damages or injunctive relief under state, federal and foreign laws, reputational damage, and decreased revenues.

We have designed our IIoT products and solutions products to interoperate with other third party products and systems. Although we attempt to safeguard our products and solutions from cybersecurity threats, the potential for cyber security attacks continues to evolve in scope and frequency.

We face operational and other risks associated with our international operations.

Risks inherent in our international business activities include, but are not limited to, the following:


•	timing of and costs associated with localizing products for foreign countries and lack of acceptance of non-local products in foreign countries;


•	that the nature and composition of our products may subject us to any number of additional legal requirements, which might include, but are not limited to, data privacy regulations, import/export regulations and other similar requirements;

•	exchange rate fluctuations;


•	the imposition of tariffs or other trade barriers on the importation of our products;


•	potentially adverse tax consequences, including restrictions on repatriation of earnings;


•	economic and political conditions in the countries where we do business;


•	differing vacation and holiday patterns in other countries, particularly in Europe;


•	increased costs of labor, particularly in China;


•	labor actions generally affecting individual countries, regions, or any of our customers, which could result in reduced demand for, or could delay delivery or acceptance of, our products; and


•	international terrorism.

Any of these factors could have a material adverse effect on our revenues, results of operations, and our financial condition.

InCompetition ~~addition~~for qualified personnel in our business areas is intense, ~~there~~and ~~could~~we may not be able to continue to retain qualified executive officers and key personnel and attract new officers and personnel when necessary. Our product development and marketing functions are largely based in Silicon Valley, which is a ~~number~~highly competitive marketplace. It may be particularly difficult to recruit, relocate and retain qualified personnel in this geographic area. Moreover, the cost of ~~follow-on~~living, ~~effects~~including the cost of housing, in Silicon Valley is known to be high. Because we are legally prohibited from ~~the~~making ~~credit~~loans ~~crisis~~to onexecutive officers, we will not be able to assist potential key personnel as they acquire housing or incur other costs that might be associated with joining our ~~business~~company. We may need to invest significant amounts of cash and equity to attract and retain new employees and expend significant time and resources to identify, recruite, train, and integrate such asemployees, and we may never realize returns on these investments. In addition, if we lose the ~~insolvency~~services of ~~certain~~any of our key ~~customers,~~personnel ~~which~~and ~~could~~are ~~impair~~not ~~our~~able ~~distribution~~to ~~channels~~find orsuitable ~~result~~replacements in a timely manner or fail to adequately plan for the ~~inability~~succession of key personnel, our ~~customers~~business tocould ~~obtain~~be ~~credit~~disrupted, other key personnel may decide to ~~finance~~leave, ~~purchases~~and ofwe ~~our~~may ~~products~~incur increased operating expenses in finding and compensating their replacements.

This uncertainty about future economic and political conditions continues to make it difficult for us to forecast operating results and to make decisions about future investments. We continue to see the effects of the tentative economy on our IIoT revenues.

If economic activity in the U.S. and other countries’ economies remains weak, many customers may continue to delay, reduce, or even eliminate their purchases of networking technology products. This could result in reductions in sales of our products, longer sales cycles, slower adoption of our technologies, increased price competition, and increased exposure to excess and obsolete inventory. For example, distributors could decide to reduce inventories of our products. If conditions in the global economy, U.S. economy or other key vertical or geographic markets we serve remain uncertain or continue to be weak, we would experience material negative impacts on our business, financial condition, results of operations, cash flow, capital resources, and liquidity.

Our executive officers and technical personnel are critical to our business.

Our success depends substantially on the performance of our executive officers and key employees. Due to the specialized technical nature of our business, we are particularly dependent on our Chief Executive Officer and other executive officers, as well as our technical personnel. Our future success will depend on our ability to attract, integrate, motivate and retain qualified executive, managerial, technical, sales, and operations personnel, particularly given the overall economic climate and the emphasis on reducing expenses at our company.

Competition for qualified personnel in our business areas is intense, and we may not be able to continue to retain qualified executive officers and key personnel and attract new officers and personnel when necessary. Our product development and marketing functions are largely based in Silicon Valley, which is a highly competitive marketplace. It may be particularly difficult

to recruit, relocate and retain qualified personnel in this geographic area. Moreover, the cost of living, including the cost of housing, in Silicon Valley is known to be high. Because we are legally prohibited from making loans to executive officers, we will not be able to assist potential key personnel as they acquire housing or incur other costs that might be associated with joining our company. In addition, if we lose the services of any of our key personnel and are not able to find suitable replacements in a timely manner, our business could be disrupted, other key personnel may decide to leave, and we may incur increased operating expenses in finding and compensating their replacements.

If we are unable to obtain additional funds when needed, our business could suffer.

For the last several years, our combined cash, cash equivalent, and short-term investment balance has declined. As we continue to implement our long-term strategic focus on the IIoT business, including the outdoor lighting controls market, this trend may continue.

As our cash balances decline, customers or potential customers may become less interested in doing business with us, or we may not satisfy the financial criteria they have established for their suppliers. In addition, from time to time we may also decide to use a portion of our cash balances to settle alleged warranty issues that may arise with our customers or¸ as noted under the heading "Legal Proceedings," in connection with litigation. We may do so even if we do not believe we have liability to our customers or in connection with such litigation, in order to limit our risk, reduce outlays to third party providers, and for administrative convenience. In the future, to the extent that our revenues grow or as we may determine necessary to maintain adequate supply levels, we may experience higher levels of inventory and accounts receivable, which will also use our cash balances. In addition, to the extent we plan to make alternate uses of our facilities, we may incur additional cash expenditures. We may also use our cash reserves to strategically acquire or invest in other companies, products, or technologies that are complementary to our business. Lastly, our combined cash, cash equivalents, and short-term investment balances could be negatively affected by the various risks and uncertainties that we face, especially in light of our focus on the nascent and emerging IIoT things market, and any changes in our planned cash outlay could negatively affect our existing cash reserves.

There can be no assurance that we will be able to obtain financing in the future, including, but not limited to, being able to draw on funds under our existing credit facilities or being able to incur indebtedness or sell equity if that became necessary or desirable. In addition, if we do not meet our revenue targets, our use of our cash balances would increase due to the fact that a significant portion of our operating expenses are fixed. If we were not able to obtain additional financing when needed, or on acceptable terms, our ability to invest in additional research and development resources and sales and marketing resources could be adversely affected, which could hinder our ability to sell competitive products into our markets on a timely basis and harm our business.19

There can be no assurance that we will be able to obtain financing on terms acceptable to us, or at all, in the future. In addition, if we do not meet our revenue targets, our use of our cash balances would increase due to the fact that a significant portion of our operating expenses are fixed. If we are not able to obtain additional financing when needed, or on acceptable terms, our ability to support our business growth, invest in additional research and development and sales and marketing, or respond to business opportunities, challenges, or other circumstances could be adversely affected, and our business may be harmed.

Our current stock price and corresponding market valuation could give rise to stockholder activism or hostile takeover attempts, which could be harmful to our business.

Because the current trading price of our common stock and aggregate market capitalization are low, there is a risk that we could face stockholder activism or hostile takeover attempts, which could divert management’s attention from its strategic plan to build stockholder value through the expansion of our lighting solutions business. If the IIoT market in general, and the outdoor lighting market segment in particular, do not materialize as anticipated, if our control networking solutions and other product offerings are not accepted and utilized, or if we are subject to a hostile takeover at a depressed valuation, we may have to devote a significant amount of time and resources to address these matters without any return on our investment. This could cause us to suffer significant financial losses and could also have a negative impact on our reputation and results of operations, any of which would likely cause our stock price to decline.

Voluntary and/or industry standards and governmental regulatory actions in our markets could limit our ability to sell our products.

Standards bodies, which are formal and informal associations that attempt to set voluntary, non-governmental product standards, are influential in many of our target markets. We participate in many voluntary and/or industry standards organizations around the world in order to help prevent the adoption of exclusionary standards as well as to promote standards for our products. However, we do not have the resources to participate in all standards processes that may affect our markets, and our efforts to influence the direction of those standards bodies in which we do participate may not be successful. Many of our competitors have significantly more resources focused on standards activities and may influence those standards in a way that would be disadvantageous to our products and thereby make it difficult for us to achieve our business and financial objectives.

Many of our products and the industries in which they are used are subject to U.S. and foreign regulation. In addition, the markets for our IIoT products may experience a movement towards standards based protocols driven by governmental action, such as those being considered in the U.S. by the National Institute of Standards and Technology. To the extent that we do not adopt such protocols or do not succeed in achieving adoption of our own protocols as standards or de facto standards, sales of our IIoT products may be adversely affected. Moreover, even if our own protocols are adopted as standards, we run the risk that we could lose business to competing implementations.

19The adoption of voluntary and/or industry standards or the passage of governmental regulations, for example by state utility commissions or national regulatory bodies such as Federal Energy Regulatory Commissions in the United States and PTB or BSI in Germany, that are incompatible with our products or technology could limit the market opportunity for our products or result in increased costs, which could harm our revenues, results of operations, and financial condition.

To the extent that we do not adopt such protocols or do not succeed in achieving adoption of our own protocols as standards or de facto standards, sales of our IIoT products may be adversely affected. Moreover, even if our own protocols are adopted as standards, we run the risk that we could lose business to competing implementations.

The adoption of voluntary and/or industry standards or the passage of governmental regulations, for example by state utility commissions or national regulatory bodies such as FERC in the United States and PTB or BSI in Germany, that are incompatible with our products or technology could limit the market opportunity for our products or result in increased costs, which could harm our revenues, results of operations, and financial condition.

We are subject to numerous governmental regulations concerning the manufacturing and use of our products. We must stay in compliance with all such regulations and any future regulations. Any failure to comply with such regulations, and the unanticipated costs of complying with future regulations, may adversely affect our business, financial condition, and results of operations.

We manufacture and sell products incorporating electronic components that may contain materials that are subject to government regulation in the locations in which our products are manufactured and assembled, as well as the locations where we sell our products. Since we operate on a global basis, maintaining compliance with regulations concerning the materials used in our products is a complex process that requires continual monitoring of regulations and ongoing compliance procedures. For example, in 2012 the European Union issued recast regulations regarding the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment ("RoHS"), and in 2014, the SEC rules requiring companies to publicly disclose their use of "conflict minerals" that originated in the Democratic Republic of the Congo (DRC) or an adjoining country also become effective. The adoption of any unanticipated new regulations that significantly impact the various components we use or require that we use more expensive components would have a material adverse impact on our business, financial condition and results of operations.

Our reliance on third-party manufacturers exposes us to the risk that conflict minerals that are contained in our products have originated in the DRC or an adjoining country. We have incurred and expect to incur additional costs to comply with the disclosure requirements. Moreover, the implementation of these requirements could adversely affect the sourcing, availability and pricing of materials used in the manufacture of our products to the extent that there may be only a limited number of suppliers offering “conflict free” minerals that can be used in our products. There can be no assurance that we will be able to obtain such minerals in sufficient quantities or at competitive prices. We may also encounter customers who require that all of the components of our products be certified as conflict free. If we are not able to meet customer requirements, such customers may choose to not purchase our products, which could impact our sales.

requirements. Moreover, the implementation of these requirements could adversely affect the sourcing, availability and pricing of materials used in the manufacture of our products to the extent that there may be only a limited number of suppliers offering “conflict free” minerals that can be used in our products. There can be no assurance that we will be able to obtain such minerals in sufficient quantities or at competitive prices. We may also encounter customers who require that all of the components of our products be certified as conflict free. If we are not able to meet customer requirements, such customers may choose to not purchase our products, which could impact our sales.

Our manufacturing processes, including the processes used by our suppliers, are also subject to numerous governmental regulations that cover both the use of various materials as well as environmental concerns. Since we and our suppliers operate on a global basis, maintaining compliance with regulations concerning our production processes is also a complex process that requires continual monitoring of regulations and ongoing compliance procedures. For example, environmental issues such as pollution and climate change have seen significant legislative and regulatory interest on a global basis. Changes in these areas could directly increase the cost of energy, which may have an impact on the way we or our suppliers manufacture products or use energy to produce our products. In addition, any new regulations or laws in the environmental area might increase the cost of raw materials we use in our products. We are currently unable to predict how any such changes will impact us and if any such impact could be material to our business. Any new law or regulation that significantly increases our costs of manufacturing or causes us or our suppliers to significantly alter the way that our products are manufactured would have a material adverse effect on our business, financial condition and results of operations.

Liabilities resulting from defects in or misuse of our products, whether or not covered by insurance, may delay our revenues and increase our liabilities and expenses.

Our products are manufactured with highly complex electronic components and may, as a result, contain or may be alleged to contain errors or failures, including those relating to actual or potential security breaches. In addition, our customers or their installation partners may improperly install or implement our products, which could delay completion of a deployment or hinder our ability to win a subsequent award. Furthermore, because of the low cost and interoperable nature of our IIoT products, LONWORKS technology could be used in a manner for which it was not intended.

Even if we determine that an alleged error or failure in our products does not exist, we may incur significant expense and shipments and revenues may be delayed while we analyze the alleged error or failure. If errors or failures are found in our products, we may not be able to successfully correct them in a timely manner, or at all, and our reputation may suffer. Such errors or failures could delay our product shipments and divert our engineering resources while we attempt to correct them. In addition, we could decide to extend the warranty period, or incur other costs outside of our normal warranty coverage, to help address any known errors or failures in our products and mitigate the impact on our customers. For example, we could decide to replace defective products at a cost that is significantly higher than the value of the original products. This could delay our revenues and increase our expenses.

errors or failures in our products and mitigate the impact on our customers. For example, we could decide to replace defective products at a cost that is significantly higher than the value of the original products. This could delay our revenues and increase our expenses.

To address these issues, the agreements we maintain with our customers may contain provisions intended to limit our exposure to potential errors and omissions claims as well as any liabilities arising from them. However, our customer contracts may not effectively protect us against the liabilities and expenses associated with errors or failures attributable to our products.

Defects in our products may also cause us to be liable for losses in the event of property damage, harm or death to persons, claims against our directors or officers, and the like. For example, our outdoor lighting control products operate in a variety of settings under diverse conditions that may present the risk of product failure, which could subject us to liability. For instance, a failure of our automated smart lighting product used by a customer to enhance security could subject us to liability in the event of unlawful activity by third parties. Moreover, our IIoT products may present risks beyond our control such as operational misuse that could ultimately subject us to liability. Such liabilities could harm our reputation, expose our company to liability, and adversely affect our operating results and financial position.

To help reduce our exposure to these types of liabilities, we currently maintain property, general commercial liability, errors and omissions, directors and officers, and other lines of insurance. However, it is possible that such insurance may not be available in the future or, if available, may be insufficient in amount to cover any particular claim, or we might not carry insurance that covers a specific claim. In addition, we believe that the premiums for the types of insurance we carry will continue to fluctuate from period to period. Significant cost increases could also result in increased premiums or reduced coverage limits. Consequently, if we elect to reduce our coverage, or if we do not carry insurance for a particular type of claim, we will face increased exposure to these types of claims.

We may be unable to realize the benefits of our net operating loss carry-forwards (“NOLs”).

NOLs may be carried forward to offset federal and state taxable income in future years and eliminate income taxes otherwise payable on such taxable income, subject to certain adjustments. Based on current federal and state corporate income tax rates, our NOLs and other carry-forwards could provide a benefit to us, if fully utilized, of significant future tax savings. However, our ability to use these tax benefits in future years will depend upon the amount of our otherwise federal and state taxable income. If we do not have sufficient federal and state taxable income in future years to use the tax benefits before they expire, we will lose the benefit of these NOLs permanently. Consequently, in addition to dependence on the generation of future business profits, our ability to use the tax benefits associated with our substantial NOLs will depend significantly on our success in identifying suitable acquisition or investment candidates, and once identified, successfully consummating an acquisition of or investment in these candidates.

Additionally, federal NOLs are subject to annual limitations under the change of ownership rules within Section 382 of the Internal Revenue Code. In general, an ownership change occurs when the percentage of stock held by one or more 5-percent shareholders increases by more than 50 percentage points over the lowest stock ownership held by such shareholders at any time within a prescribed period, usually three years. If an ownership change were to occur, we may be unable to use a significant portion of our NOLs to offset taxable income. As discussed in Note 7 to our consolidated financial statements included in our Annual Report on Form 10-K, filed with the Securities and Exchange Commission in March 2017, on April 22, 2016, the Company’s Board of Directors adopted a Tax Benefit Preservation Plan (“Tax Plan”) intended to reduce the likelihood that changes in the Company’s investor base have the unintended effect of limiting the Company’s use of its tax benefits. The Tax Plan is intended to require any person acquiring shares of the Company’s securities equal to or exceeding 4.99% of the Company’s outstanding shares to obtain the approval of the Board of Directors. This would protect the tax benefits because changes in ownership by a person owning less than 4.99% of the Company’s stock are considered and included in one or more public groups in the calculation of “ownership change” for purposes of Section 382 of the Code. However, there can be no assurance that the Tax Plan would be effective under all circumstances. Moreover, the Tax Plan, as amended on April 17, 2017, will expire on April 25, ~~2017~~2019, unless renewed by our Board of Directors.

The amount of NOLs that we have claimed has not been audited or otherwise validated by the U.S. Internal Revenue Service (“IRS”). The IRS could challenge our calculation of the amount of our NOLs or our determinations as to when a prior change in ownership occurred, and other provisions of the Internal Revenue Code may limit our ability to carry forward our NOLs to offset taxable income in future years. If the IRS was successful with respect to any such challenge, the potential tax benefit of the NOLs to us could be substantially reduced.

Lastly, in December 2017, the Tax Cuts and Jobs Act ("the Act") was signed into law. Among other changes is a permanent reduction in the federal U.S. corporate income tax rate from 35% to 21%, effective January 1, 2018. As a result of the change in the corporate income tax rate, the value of our NOLs has decreased.

We have limited ability to protect our intellectual property rights.

Our success depends significantly upon our intellectual property rights, which can vary significantly from jurisdiction to jurisdiction. We rely on a combination of patent, copyright, trademark and trade secret laws, non-disclosure agreements and other contractual provisions to establish, maintain and protect these intellectual property rights, all of which afford only limited protection, particularly in those countries that lack robust or accessible enforcement mechanisms. For example, we have in the past and may in the future form joint ventures with foreign companies, including those in China, where intellectual property mechanisms are generally less stringent than those found in the U.S. We have also outsourced certain development activities to third parties. If any of our patents fail to protect our technology, or if we do not obtain patents in certain countries, our competitors may find it easier to offer equivalent or superior technology. In addition, our trade secrets or other intellectual property that we license to third parties could be used improperly or otherwise in violation of the license terms.

We have also registered or applied for registration for certain trademarks, and will continue to evaluate the registration of additional trademarks as appropriate. If we fail to properly register or maintain our trademarks, or to otherwise take all necessary steps to protect our trademarks, the value associated with the trademarks may diminish. In addition, if we fail to protect our trade secrets or other intellectual property rights, we may not be able to compete as effectively in our markets.

Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our products or services or use information that we regard as proprietary, or it may not be economically feasible to enforce them. Any of our patents, trademarks, copyrights, trade secrets, or intellectual property rights could be challenged, invalidated or circumvented. In addition, we cannot assure you that we have taken or will take all necessary steps to protect our intellectual property rights. Third parties may also independently develop similar technology without breach of our trade secrets or other proprietary rights. In addition, the laws of some foreign countries, including several in which we operate or sell our products, do not protect proprietary rights to as great an extent as do the laws of the United States, and it may take longer to receive a remedy from a court outside of the United States. Also, some of our products are licensed under shrink-wrap license agreements that are not signed by licensees and therefore may not be binding under the laws of certain jurisdictions.

the United States. Also, some of our products are licensed under shrink-wrap license agreements that are not signed by licensees and therefore may not be binding under the laws of certain jurisdictions.

From time to time, litigation may be necessary to defend and enforce our proprietary rights. As a result, we could incur substantial costs and divert management resources, which could harm our business, regardless of the final outcome. Despite our efforts to safeguard and maintain our proprietary rights both in the United States and abroad, we may be unsuccessful in doing so. Also, the steps that we take to safeguard and maintain our proprietary rights may be inadequate to deter third parties from infringing, misusing, misappropriating, or independently developing our technology or intellectual property rights, or to prevent an unauthorized third party from misappropriating our products or technology.

Our business may suffer if it is alleged or found that our products infringe the intellectual property rights of others, or if we are unable to secure rights to use the intellectual property rights of others on reasonable terms.

We may be contractually obligated to indemnify our customers or other third parties that use our products in the event our products are alleged to infringe a third party’s intellectual property rights. From time to time, we may also receive notice that a third party believes that our products may be infringing patents or other intellectual property rights of that third party. Responding to those claims, regardless of their merit, can be time consuming, result in costly litigation, divert management’s attention and resources, and cause us to incur significant expenses. We do not insure against infringement of a third party’s intellectual property rights.

As the result of such a claim, we may elect or be required to redesign our products that are alleged to infringe the third party’s patents or other intellectual property rights, which could cause those product offerings to be delayed. Or we could be required to cease distributing those products altogether. In the alternative, we could seek a license to the third party’s intellectual property. Even if our products do not infringe, we may elect to take a license or settle to avoid incurring litigation costs. However, it is possible that we would not be able to obtain such a license or settle on reasonable terms, or at all.

In some cases, even though no infringement has been alleged, we may attempt to secure rights to use the intellectual property rights of others that would be useful to us. We cannot guarantee that we would be able to secure such rights on reasonable terms, or at all.

Lastly, our customers may not purchase our products if they are concerned our products may infringe third party intellectual property rights. This could reduce the market opportunity for the sale of our products and services.

Any of the foregoing risks could have a material adverse effect on our revenues, results of operations, and financial condition.

We face currency risks associated with our international operations.

We have operations located in seven countries and our products are sold in many more countries around the world. Revenues from international sales, which include both export sales and sales by international subsidiaries, accounted for about 68.2%, 71.3% and 72.4%, of our total revenues for the years ended December 31, 2016, 2015, and 2014, respectively. We expect that international sales will continue to constitute a significant portion of our total revenues. Given our high dependency on sales of our products into Europe, the ongoing financial crisis in that region, which may be adversely impacted by the "Brexit" vote in the United Kingdom, could adversely affect our financial results.

Changes in the value of currencies in which we conduct our business relative to the U.S. dollar have caused and could continue to cause fluctuations in our reported financial results. The three primary areas where we are exposed to foreign currency fluctuations are revenues, cost of goods sold, and operating expenses.

In general, we sell our products to foreign customers primarily in U.S. dollars. As such, fluctuations in exchange rates have had, and could continue to have, an impact on revenues. If the value of the dollar rises, our products will become more expensive to our foreign customers, which could result in their decision to postpone or cancel a planned purchase.

With respect to the relatively minimal amount of our revenues generated in foreign currencies, our historical foreign currency exposure has been related primarily to the Japanese Yen and has not been material to our consolidated results of operations. However, we will face increased exposure to foreign currency risk if, in the future, our foreign customers require us to price our products in a local currency.

In addition, for our cost of goods sold, our products are generally assembled by CEMs in China. Although our transactions with these companies are presently denominated in U.S. dollars, in the future they may require us to pay in their local currency, or demand a U.S. dollar price adjustment or other payment to address a change in exchange rates, which would increase our cost to procure our products. This is particularly a risk in China, where any future revaluations of the Chinese currency against the U.S. dollar could result in significant cost increases. In addition, increases in labor costs in the markets where our products are manufactured could also result in higher costs to procure our products. For example, China has recently experienced overall wage increases, which our CEMs have generally passed along to us.

We use the local currency to pay for our operating expenses in the various countries where we have operations. If the value of the U.S. dollar declines as compared to the local currency where the expenses are incurred, our expenses, when translated back into U.S. dollars, will increase.

To date, we have not hedged any of our foreign currency exposures and currently do not maintain any hedges to mitigate our foreign currency risks. Consequently, any resulting adverse foreign currency fluctuations could significantly harm our revenues, cost of goods sold, or operating expenses.

Fluctuations in our operating results may cause our stock price to decline.

Our quarterly and annual results have varied significantly from period to period, and we have sometimes failed to meet market expectations. Moreover, we have a history of losses and negative cash flow and cannot assure you that we will achieve sustained profitability in the future. Our future operating results will depend on many factors, many of which are outside of our control, including the following:

• orders may be cancelled;

• the mix of products and services that we sell may change to a less profitable mix;

• shipment, payment schedules, and product acceptance may be delayed;

• our products may not be purchased by OEMs, systems integrators, service providers and end-users at the levels we project;

• our ability to develop products that comply with future regulations and trade association guidelines;

• the revenue recognition rules relating to certain of our products could require us to defer some or all of the revenue associated with product shipments until certain conditions, such as delivery and acceptance criteria for our software and/or hardware products, are met in a future period;

• our CEMs may not be able to provide quality products on a timely basis, especially during periods where capacity in the CEM market is limited;

• our products may not be manufactured in accordance with specifications or our established quality standards, or may not perform as designed;

• downturns in any customer’s or potential customer’s business, or declines in general economic conditions, could cause significant reductions in capital spending, thereby reducing the levels of orders from our customers;

• we may incur costs associated with any future business acquisitions; and

• any future impairment charges related to our intangible assets that are required to be recorded under generally accepted accounting principles in the United States may negatively affect our earnings and financial condition.

Any of the above factors could, individually or in the aggregate, have a material adverse effect on our results of operations and our financial condition, which could cause our stock price to decline.

We may be unable to anticipate or fail to adequately mitigate against increasingly sophisticated methods to engage in illegal or fraudulent activities against us.

Despite any defensive measures we take to manage threats to our business, our risk and exposure to these matters remain heightened because of, among other things, the evolving nature of such threats in light of advances in computer capabilities, new discoveries in the field of cryptography, new and sophisticated methods used by criminals including phishing, social engineering or other illicit acts, or other events or developments that we may be unable to anticipate or fail to adequately mitigate. These threats, events, and developments could lead to, for example, unauthorized access to or acquisition of our sensitive business information or intellectual property, or the personal data of our employees. If any such efforts against us were to be successful, itwe could face financial and legal liability and suffer damage to our business and reputation, any of which could have a material adverse effect on our results of operations and financial condition.

Future acquisitions, strategic investments, partnerships or alliances could be difficult to identify and integrate, divert the attention of management, disrupt our business, dilute stockholder value and adversely affect our ~~operating~~ results of operations and financial condition.

As opportunities present themselves, we may from time to time evaluate and enter into strategic partnerships or transactions involving acquisitions of or investments in other businesses, products or technologies that we believe could complement or expand our services, enhance our technical capabilities or otherwise offer growth opportunities. The pursuit of potential transactions may divert the attention of management and cause us to incur various expenses in identifying, investigating, and pursuing suitable opportunities, whether or not transactions are ultimately completed. If we acquire businesses, we may not be able to integrate successfully the acquired personnel, operations and technologies, or effectively manage the combined business following the acquisition. We may not be able to find and identify desirable opportunities or be successful in entering into an agreement with respect to the opportunities that we do identify. Acquisitions and other transactions could also result in dilutive issuances of equity securities, use of our existing cash reserves or the incurrence of debt, which could adversely affect our operating results. In addition, if a transaction fails to meet our expectations, our operating results, business and financial condition may suffer.

securities, use of our existing cash reserves or the incurrence of debt. In addition, a transaction may fail to meet our expectations. The occurrence of any of these risks could harm our results of operations, business and financial condition.

Natural disasters, power outages, and other factors outside of our control such as widespread pandemics could disrupt our business.

We must protect our business and our network infrastructure against damage from earthquake, flood, hurricane and similar events, as well as from power outages. Our corporate headquarters is located in the San Francisco Bay Area, a region known for earthquakes. A natural disaster, power outage, or other unanticipated problem could also adversely affect our business by, among other things, harming our primary data center or other internal operations, limiting our ability to communicate with our customers, limiting our ability or our partners’ or customers’ ability to sell or use our products, affecting our third party developer’s ability to complete developments on schedule or at all, or affecting our suppliers’ ability to provide us with components or products. These risks bay be further increased if the disaster recover plans for us and our suppliers prove to be inadequate. For example, the 2011 earthquake and tsunami in Japan adversely impacted our revenues from customers located in Japan and/or our ability to source parts from companies located in Japan. Shortly after the earthquake, we received notice from Toshiba (one of two manufacturers of the Neuron Chip - an important component that we and our customers use in control network devices), that they would no longer be able to manufacture Neuron Chips due to earthquake damage suffered at the semiconductor manufacturing facility that produced the Neuron Chips. However, the abrupt termination of Toshiba’s Neuron Chip manufacturing capability caused a disruption in supply and an increase in prices from the remaining supplier, Cypress Semiconductor. We do not insure against several natural disasters, including earthquakes.

Any outbreak of a widespread communicable disease pandemic, such as the outbreak of the H1N1 influenza virus in 2009, could similarly impact our operations. Such impact could include, among other things, the inability for our sales and operations personnel located in affected regions to travel and conduct business freely, the impact any such disease may have on one or more of the distributors for our products in those regions, and increased supply chain costs. Additionally, any future health-related disruptions at our third-party contract manufacturers or other key suppliers could affect our ability to supply our customers with products in a timely manner, which would harm our results of operations.

ITEM 7.	MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with the consolidated financial statements and notes thereto included elsewhere in this Annual Report. The following discussion contains predictions, estimates, and other forward-looking statements that involve a number of risks and uncertainties about our business. These statements may be identified by the use of words such as “we believe,” “expect,” “anticipate,” “intend,” “plan,” “goal,” “continues,” “may” and similar expressions. Forward-looking statements include statements that refer to projections of our future financial performance, our anticipated growth and trends in our businesses, and other characterizations of future events or circumstances. In particular, these statements include statements such as: our projections of revenues; estimates of our future gross margins and restructuring charges; statements regarding reinvesting a portion of our earnings from foreign operations; plans to use our cash reserves to strategically acquire other companies, products, or technologies; our projections of our combined cash, cash equivalent and short term investment balance; the sufficiency of our cash reserves to meet cash requirements; our expectations that our revenues will not fluctuate significantly due to a fluctuation in foreign currency sales; our forecasts regarding our sales and marketing expenses; and estimates of our interest income and tax exposure. Such statements are based on our current expectations and could be affected by the uncertainties and risk factors described throughout this filing and particularly in the “Risk Factors” section. Therefore, our actual results may differ materially and adversely from those expressed in any forward-looking statements. We undertake no obligation to review or update publicly any forward-looking statements for any reason.

EXECUTIVE OVERVIEW

Echelon Corporation was incorporated in California in February 1988 and reincorporated in Delaware in January 1989. We went public on the NASDAQ market under the symbol "ELON" in July, 1998. We are based in Santa Clara, California, and maintain offices in several foreign countries throughout Europe and Asia. Our products enable "things" in commercial and industrial applications — such as air conditioners, lighting, manufacturing equipment, electricity meters, light switches, thermostats, and valves — to be made “smart” and inter-connected, part of an emerging market known as the Industrial Internet of Things ("IIoT").

Our widely deployed, open standard, multi-vendor energy control networking platform powers applications for smart cities, smart buildings, and smart campuses that help customers save on their energy usage; prevent failure or reduce failure duration; reduce carbon footprint; improve safety, comfort, and convenience; and more. Our solutions, which feature a programmable, distributed intelligence architecture that is designed for both high reliability and fast action, are implemented over the powerline or through wireless communication systems for flexibility in installation and operation.

We offer two product lines, the first of which is comprised of chips, modules, gateways, and design and management software that enables Original Equipment Manufacturers ("OEMs") to quickly design and bring to market interoperable smart systems for their commercial and industrial customers. These products are generally marketed under the LONWORKS and IzoT brand names. We refer to revenues from these products as "embedded systems" revenues ~~(previously called "building automation")~~.

Our second product line is a range of control networking solutions designed specifically for the lighting market within the IIoT. As this market continues its transition to solid state lighting, or LEDs, we have focused our initial offerings on outdoor lighting control solutions, as we believe that the incremental energy savings, maintenance benefits, and safety improvements resulting from the implementation of controls offers a compelling return on investment. In addition, due to the abundance of lighting fixtures in most locations, the lighting control system can host a variety of "smart" applications that can further improve safety and comfort on roadways, in parking lots and garages, on campuses, in tunnels, and more. Our lighting control solutions consist of wired and wireless control nodes placed at the lighting fixtures of a wide variety of manufacturers, “smart” gateways for interconnecting the control nodes, and a software-based Central Management System, or CMS, which is used for startup, commissioning, management, and monitoring of the lighting network. These solutions are sold to end users typically through manufacturers' representatives, energy services companies, and distributors, and are generally marketed under the LumInsight and Lumewave by Echelon brand names. We refer to revenues from these products as "outdoor lighting" revenues.

Prior to the third quarter of 2014, our Company operated in two operating segments, the IIoT segment, and the Grid segment. In the third quarter of 2014, we announced and completed the sale of our Grid operating segment to S&T AG ("S&T"), a publicly traded European IT systems provider with an existing focus on smart energy products and services. We have classified the results of operations of the Grid business as discontinued operations for the year ended December 31, 2014. For more information on the sale of our Grid division, please refer to Note 5 - Discontinued Operations, in the Notes to Consolidated Financial Statements in Part IV, Item 15 of this report.27

29The following tables provide an overview of key financial metrics for the years ended December 31, 2017 and 2016 that our management team focuses on in evaluating our financial condition and operating performance (in thousands, except percentages).

During the quarter ended June 30, 2015, we terminated the lease agreements for our corporate headquarters facility in San Jose, California. These leases were scheduled to expire in March 2020 and had been historically accounted for under authoritative guidance pertaining to leases in which we were both involved in the construction of the lease assets and for which certain sale-leaseback criteria were not met. This resulted in Echelon being the "deemed owner" of the two buildings for accounting purposes only. Accordingly, the leases associated with these facilities were historically accounted for as financing obligations.

•

Cash, cash equivalents, restricted investments, and short-term investments: During 2017, our cash, cash equivalents, restricted investments, and short-term investment balance decreased by 11.1%, from $23.0 million at December 31, 2016 to $20.5 million at December 31, 2017. This decrease was primarily the result of cash used in operations of $2.2 million (driven primarily by our net loss of $4.6 million less non-cash charges for depreciation and amortization, and stock based compensation).

• Net revenues: Our total revenues decreased by 16.5% during 2016 as compared to 2015. Excluding component sales to Enel, which decreased from $4.9 million in 2015 to $1.3 million in 2016, our revenues decreased by 8.3% during 2016 as compared to 2015. This decrease was primarily due to a reduction in sales of our products in all the regions that we serve. We have seen a loss of market share over the last several years, as a result of reductions in IIoT related research and development and marketing expenses during the period in which the Company was pursuing its Grid business, which was sold in 2014. This impacted sales of our LONWORKS portfolio of products in particular, which has caused a decrease in our IIoT revenues.

• Gross margin: Our gross margin decreased by 1.6 percentage points during 2016 as compared to 2015. The decrease was primarily due to a change in the mix of products sold as well as lower overall revenue levels.

• Operating expenses: Our operating expenses decreased by 36.4% during 2016 as compared to 2015. This continues a trend we began several years ago and is primarily due to a reduction in our facilities expenses as well as reduced compensation related expenses resulting from the restructuring actions we have undertaken.

• Net loss: We generated a net loss of $4.1 million during 2016, which was a decrease from the net loss of $13.2 million in 2015. Excluding the impact of non-cash stock-compensation charges, impairment charges, adjustments to the expected Lumewave consideration, lease termination charges, and restructuring charges, our net loss decreased by approximately $1.1 million, or 24.4%, in 2016 as compared to 2015. This reduction was primarily the result of an overall decrease in our operating expenses.

• Cash, cash equivalents, restricted investments, and short-term investments: During 2016, our cash, cash equivalents, restricted investments, and short-term investment balance decreased by 11.6%, from $26.1 million at December 31, 2015 to $23.0 million at December 31, 2016. This decrease was primarily the result of cash used in operations of $3.0 million (driven primarily by our net loss of $4.1 million less non-cash charges for depreciation and amortization, and stock based compensation).

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. Note 1, “Significant Accounting Policies” of Notes to Consolidated Financial Statements in this Annual Report on Form 10-K describes the significant accounting policies and methods used in the preparation of our consolidated financial statements. The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, including those related to our stock-based compensation, allowance for doubtful accounts, inventories, and commitments and contingencies. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions.

We believe the following critical accounting policies and estimates relate to those policies that are most important to the presentation of our consolidated financial statements and require the most difficult, subjective, and complex judgments.

Revenue Recognition. Our revenues are derived from the sale and license of our products and to a lesser extent, from fees associated with training, technical support, and custom software design services offered to our customers. Product revenues consist of revenues from hardware sales and software licensing arrangements. Service revenues consist of product technical support (including software post-contract support services), training, and custom software development services.

For non-distributor hardware sales, including sales to third party manufacturers, these criteria are generally met at the time of delivery to the customer's carrier. However, for arrangements that contain contractual acceptance provisions, revenue recognition may be delayed until acceptance by the customer or the acceptance provisions lapse unless we can objectively demonstrate that the contractual acceptance criteria have been satisfied, which is generally accomplished by establishing a history of acceptance for the same or similar products. For sales made to our distributor partners, revenue recognition criteria are generally met at the time the distributor sells the products through to its end-use customer. Service ~~revenues~~revenue ~~consist~~is recognized as the training services are performed, or ratably over the term of ~~product~~the ~~technical~~support period.

With the exception of sales to distributors, the Company's customers are generally not entitled to return products for a refund. For sales to distributors, due to contractual rights of return and other factors that impact our ability to make a reasonable estimate of future returns and other sales incentives, revenues are not recognized until the distributor has shipped our products to the end customer.

We recognize revenue when persuasive evidence of an arrangement exists, delivery to the customer's carrier (and acceptance, as applicable) has occurred, the sales price is fixed or determinable, collectability is probable, and there are no post-delivery obligations. For non-distributor hardware sales, including sales to third party manufacturers, these criteria are generally met at the time of delivery to the customer's carrier. However, for arrangements that contain contractual acceptance provisions, revenue recognition may be delayed until acceptance by the customer or the acceptance provisions lapse unless we can objectively demonstrate that the contractual acceptance criteria have been satisfied, which is generally accomplished by

establishing a history of acceptance for the same or similar products. For sales made to our distributor partners, revenue recognition criteria are generally met at the time the distributor sells the products through to its end-use customer. Service revenue is recognized as the training services are performed, or ratably over the term of the support period.

We account for the rights of return, price protection, rebates, and other sales incentives offered to distributors of our

products as a reduction in revenue. With the exception of sales to distributors, the Company's customers are generally not

entitled to return products for a refund. For sales to distributors, due to contractual rights of return and other factors that impact

our ability to make a reasonable estimate of future returns and other sales incentives, revenues are not recognized until the

distributor has shipped our products to the end customer.

Inventory Valuation. At each balance sheet date, we evaluate our ending inventories for excess quantities and obsolescence. In general, the evaluation for excess quantities includes analyses of historical sales levels by product and projections of future demand. In general, inventories on hand in excess of one year's forecasted demand are deemed to be excess. However, in certain instances when the facts and circumstances for a particular item warrant an extended view, periods of longer than one year are used to determine excess supplies. In performing these analyses, management must make significant judgments in determining the appropriate time horizon over which to analyze for excess inventories.

For most of our products, our customers generally buy from a portfolio of “off-the-shelf” or standard products. In addition, our revenues are generally composed of a larger volume of smaller dollar transactions. Accordingly, while any single customer's demand for a given product may fluctuate from quarter to quarter, the fact that there are so many IIoT customers buying a standard product tends to average out increases or decreases in any individual customer's demand. This has historically resulted in a relatively stable future demand forecast for our IIoT products, which, absent outside forces such as worsening general economic conditions, management evaluates in determining its requirement for an excess inventory reserve.

our revenues are generally composed of a larger volume of smaller dollar transactions. Accordingly, while any single customer's demand for a given product may fluctuate from quarter to quarter, the fact that there are so many IIoT customers buying a standard product tends to average out increases or decreases in any individual customer's demand. This has historically resulted in a relatively stable future demand forecast for our IIoT products, which, absent outside forces such as worsening general economic conditions, management evaluates in determining its requirement for an excess inventory reserve.

In addition to providing a reserve for excess inventories, we do not value inventories that we consider obsolete. We consider a product to be obsolete when one of several factors exists. These factors include, but are not limited to, our decision to discontinue selling an existing product, the product has been re-designed and we are unable to rework our existing inventory to update it to the new version, or our competitors introduce new products that make our products obsolete.

We adjust remaining inventory balances to approximate the lower of our cost or ~~market~~net realizable value. If future demand or market conditions are less favorable than our projections, additional inventory write-downs may be required and would be reflected in cost of sales in the period the revision is made.

Impairment of Long-Lived Assets Including Goodwill. We review long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability is measured by comparing the asset's carrying value to the future undiscounted cash flows the asset is expected to generate. If long-lived assets are considered to be impaired, the impairment to be recognized equals the amount by which the carrying value of the asset exceeds its fair value. For the year ended December 31, 2014, we recognized impairments associated with certain long-lived assets associated with our Grid division and a building that we ceased use of at our previous corporate headquarters facility (see Note 3 of Notes to Consolidated Financial Statements for additional information regarding the impairment). For the years ended December 31, 2016, and December 31, 2015, we recognized no impairments of long-lived assets.

Costs in excess of the fair value of tangible and other identifiable intangible assets acquired and liabilities assumed in a purchase business combination are recorded as goodwill, which is tested for impairment using a two-step approach. We evaluate goodwill, at a minimum, on an annual basis during the first quarter and whenever events and changes in circumstances suggest that the carrying amount may not be recoverable. Impairment of goodwill is tested at the reporting unit level by comparing the reporting unit's carrying amount, including goodwill, to the fair value of the reporting unit. The fair values of the reporting units are estimated using a combination of the income approach and the market approach. If the carrying amount of the reporting unit exceeds its fair value, goodwill is considered impaired and a second step is performed to measure the amount of impairment loss, if any. For the years ended December 31, 2015 and 2014, we recognized impairments of our goodwill (see Note 10 of Notes to Consolidated Financial Statements for additional information regarding these impairments).

For these impairment analyses, we are required to estimate the fair value of the assets being evaluated. These fair value estimates require significant management judgment and are based on the best information available at the time of the analysis.

RESULTS OF OPERATIONS

The following discussion covers our results of operations for the ~~three~~two years ended December 31, ~~2016~~2017. For the year ended December 31, 2014, the results of our Grid business are reflected in the "Net loss from discontinued operations" lines in our Consolidated Statements of Operations, as we sold our Grid business in September 2014 (see Note 5 in Part IV, Item 15 of this report for further information regarding the sale of our Grid business).

33The portion of our revenues denominated in currencies other than the United States dollar, principally the Japanese Yen, was about 4.1% in 2017 and 3.9% in 2016. Our revenues will be subject to fluctuations in the exchange rates between the United States dollar and the foreign currencies in which we sell our products and services. In general, if the dollar were to weaken against these currencies, our revenues from those foreign currency sales, when converted into United States dollars, would increase. Conversely, if the dollar were to strengthen against these currencies, our revenues from those foreign currency sales, when converted into United States dollars, would decrease. The extent of this exchange rate fluctuation increase or decrease will depend on the amount of sales conducted in these currencies and the magnitude of the exchange rate fluctuation from year to year. To date, we have not hedged any of these foreign currency risks.

Excluding sales to Enel, our revenues decreased by 5.2%, or $1.8 million, during 2015 as compared to 2014. This decrease was primarily due to a $1.3 million reduction in sales made to customers in the APJ region, with the remainder coming from smaller reductions in sales made to customers in the Americas and EMEA regions. 30

Gross profit is equal to revenues less cost of revenues. Cost of revenues associated with sales of our IIoT products includes direct costs associated with the purchase of components, sub-assemblies, and finished goods, as well as indirect costs such as allocated labor and overhead; costs associated with the packaging, preparation, and shipment of products; and charges related to warranty and excess and obsolete inventory reserves. Cost of revenues associated with our IIoT services consists of employee-related costs such as salaries and fringe benefits as well as other direct and indirect costs incurred in providing training, customer support, and custom software development services. Gross margin is equal to gross profit divided by revenues.

allocated labor and overhead; costs associated with the packaging, preparation, and shipment of products; and charges related to warranty and excess and obsolete inventory reserves. Cost of revenues associated with our IIoT services consists of employee-related costs such as salaries and fringe benefits as well as other direct and indirect costs incurred in providing training, customer support, and custom software development services. Gross margin is equal to gross profit divided by revenues.

Gross margin decreased by 1.6 percentage points for the year ended December 31, 2016 as compared to 2015. The decrease was primarily due to a change in the mix of products sold as well as lower overall revenue levels.

During 2015, our gross margins increased by 0.8 percentage points as compared to 2014. This was primarily due to a change in the mix of products sold.

Our future gross margins will continue to be affected by several factors, including, but not limited to: overall revenue levels, changes in the mix of products sold, changes in our distribution strategy and use of distributors, changes in the prices charged by our suppliers, periodic charges related to excess and obsolete inventories, warranty expenses, introductions of cost reduced versions of our products, changes in the average selling prices of the products we sell, purchase price variances, and fluctuations in the level of indirect overhead spending. In addition, the impact of foreign exchange rate fluctuations and labor rates may affect our gross margins in the future. We currently outsource the manufacturing of most of our products requiring assembly to CEMs located primarily in China. To the extent labor rates were to rise further, or to the extent the U.S. dollar were to weaken against the Chinese currency, or other currencies used by our CEMs, our costs for the products they manufacture could rise, which would negatively affect our gross margins.

General and administrative expenses decreased in 2015 as compared to the same period in 2014 due primarily to lower compensation related to the 2014 restructuring actions, as well as lower excess facilities charges resulting from the termination of our corporate headquarters facility leases. Also contributing to the year over year decline was the fact that, during 2014 we incurred one-time costs associated with the sale of our Grid division and the acquisition of Lumewave. These costs did not repeat in 2015. Lastly, as mentioned earlier, during the quarter ended December 31, 2015, we concluded that the amount of contingent consideration we expect to owe the former Lumewave shareholders at the conclusion of the two-year period ending in August 2016 was less than the amount we had been providing for previously. As a result, we reduced this accrual by approximately $577,000, which was recorded as a reduction to our general and administrative expenses. 32

During the quarter ended December 31, 2015, we determined that there were indicators of a potential impairment of our goodwill, resulting primarily from the continued decline in the trading price of our common stock. As a result, we performed an impairment test of our long-lived assets, including goodwill, and concluded that a full impairment of our goodwill was warranted. This resulted in a non-cash charge of $5.7 million during the quarter.

Lease Termination Charges	$	—	$	3,337	$	—	(3,337	)	3,337	(100.0	)%	100	%

During the quarter ended June 30, 2015, we terminated the lease agreements for our corporate headquarter facility in San Jose, California. These leases were scheduled to expire in March 2020 and had been historically accounted for under authoritative guidance pertaining to leases in which we were both involved in the construction of the lease assets and for which certain sale-leaseback criteria were not met. This resulted in Echelon being the "deemed owner" of the two buildings for accounting purposes only. Accordingly, the leases associated with these facilities were historically accounted for as financing obligations.

In conjunction with the termination of these leases and associated financing obligations in May 2015, we paid an up-front lease termination charge of $10.0 million, which allowed us to remove approximately $15.3 million of building related financing obligations from our balance sheet. At the same time, we entered into a short-term lease for one of the two buildings for the remainder of 2015. As a result of the lease termination, we wrote the carrying value of the buildings and leasehold improvements down to its fair value, which was equal to the present value of the remaining lease payments under the short-term lease. The net effect of the lease termination transaction was a one-time charge of $3.3 million during the quarter ended June 30, 2015.

As a result of the sale of our Grid business on September 30, 2014, we made the decision to cease use of one of the two buildings we leased at our former corporate headquarters facility and to recharacterize the building as a rental property. Consequently, we performed an impairment analysis on this building and determined that its carrying value was not recoverable. In performing this analysis, we analyzed the expected cash flows from different sub-lease scenarios using recent lease data for similar facilities in the area, including market activity, expected tenant improvements and commissions, as well as the amount of time we believed would be required to secure a tenant for the building. As a result of this analysis, we recorded a write down of the building of $4.4 million during the third quarter of 2014.

During the fourth quarter of 2016, we undertook restructuring actions affecting approximately 7 employees to be terminated between October 2016 and ~~September~~November ~~2017~~2018, as part of an overall plan to reshape our Company for the future. In connection with this restructuring, we recorded restructuring charges of approximately $286,000 related to termination benefits for these personnel during the quarter ended December 31, 2016.

On September 30, 2014, and again in the fourth quarter of 2014, in connection with the sale of the Grid business, we undertook restructuring actions affecting approximately 44 employees who were terminated between September 2014 and March 2015, as part of the strategic plan to focus on our IIoT business. In connection with this restructuring, we recorded restructuring charges of $1.8 million, of which $1.4 million was included in the net loss from discontinued operations for the year ended December 31, 2014.

Interest and other income (expense), net primarily reflects interest earned by our company on cash and short-term investment balances as well as foreign exchange translation gains and losses related to short-term intercompany balances.

Interest and other ~~income~~expense, net ~~remained~~increased ~~relatively~~by ~~unchanged~~$1.3 million during ~~2016~~2017 as compared to the same period in ~~2015~~2016. ~~Interest and other income, net decreased during 2015 as compared to 2014.~~ This ~~decrease~~increase was primarily attributable to a $~~172,000~~1.4M ~~decrease~~increase in foreign currency remeasurement ~~gains~~losses during ~~2015~~2017 as compared to ~~2014~~2016. These foreign currency fluctuations are attributable to our foreign currency denominated short-term intercompany balances. We account for translation gains and losses associated with these balances by reflecting these amounts as either other income or loss in our consolidated statements of operations. During periods when the U.S. dollar weakens in value against these foreign currencies the associated translation losses negatively impact other income. Conversely, when the U.S. dollar strengthens, the resulting translation gains favorably impact other income.

We do not currently anticipate interest income on our investment portfolio will improve during ~~2017~~2018 as we expect interest rates to remain historically low. Future gains or losses associated with remeasuring our foreign currency denominated short-term intercompany balances will depend on the intercompany account balances as well as exchange rates in effect at the time of translation.

Interest expense on lease financing obligations was not applicable in 2016 as we terminated the leases associated with these facilities in 2015. Interest expense on lease financing obligations decreased during 2015 as compared to 2014, which was a result of the nature of this expense. As with any amortizing fixed rate loan, payments made earlier in the term of the loan are comprised primarily of interest expense with little being allocated to principal repayment. Payments made later in the term of the loan, however, have an increasing proportion of principal repayment, with less being attributable to interest expense. In addition, the reduction in 2015 was also the result of the fact that in May 2015, we terminated the leases for our former San Jose headquarters facilities and retired virtually all of the associated lease financing obligations.

The income tax expense for the years ended December 31, 2016, 2015 and 2014 was $182,000, $50,000 and $211,000, respectively. The difference between the statutory rate and our effective tax rate is primarily due to the impact of foreign taxes, changes in the valuation allowance on deferred tax assets, and changes in the accruals related to unrecognized tax benefits.

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

company to material continuing risks, contingent liabilities, or any other obligation under a variable interest in an unconsolidated entity that provides financing, liquidity, market risk, or credit risk support to us.

Lease Commitments. In September 2015, we entered into a lease agreement for our corporate headquarters facility in Santa Clara, California. This lease commenced in November 2015 and will expire in July 2019. In addition, we lease facilities under operating leases for our sales, marketing, and product development personnel located elsewhere within the United States and in several foreign countries throughout Europe and Asia. These operating leases expire on various dates through 2019, and in some instances are cancelable with advance notice. Lastly, we also lease certain equipment and, for some of our sales personnel, automobiles. These operating leases are generally less than five years in duration.

Purchase Commitments. We utilize several contract manufacturers who manufacture and test our products requiring assembly. These contract manufacturers acquire components and build product based on demand information supplied by us in the form of purchase orders and demand forecasts. These purchase orders and demand forecasts generally cover periods up to twelve months, and in rare cases, up to eighteen months. We also obtain individual components for our products from a wide variety of individual suppliers. We generally acquire these components through the issuance of purchase orders, and in some cases through demand forecasts, both of which cover periods up to twelve months.

We also utilize purchase orders when procuring capital equipment, supplies, and services necessary for our day-to-day operations. These purchase orders generally cover periods ranging up to twelve months, but in some instances cover a longer duration.

Indemnifications. In the normal course of business, we provide indemnifications of varying scope to customers against claims of intellectual property infringement made by third parties arising from the use of our products. Historically, costs related to these indemnification provisions have not been significant. However, we are unable to estimate the maximum potential impact of these indemnification provisions on our future results of operations.

As permitted under Delaware law, we have agreements whereby we indemnify our officers and directors for certain events or occurrences while the officer or director is, or was, serving at our request in such capacity. The indemnification period covers all pertinent events and occurrences during the officer’s or director’s lifetime. The maximum potential amount of future payments we could be required to make under these indemnification agreements is unlimited; however, we have director and officer insurance coverage that would enable us to recover a portion of any future amounts paid. We believe the estimated fair value of these indemnification agreements in excess of the applicable insurance coverage is minimal.

Royalties. We have certain royalty commitments associated with the shipment and licensing of certain products. Royalty expense is generally based on a U.S. dollar amount per unit shipped or a percentage of the underlying revenue. Royalty expense, which is recorded as a component of cost of revenues in our Consolidated Statements of Operations, was approximately $~~264~~260,000, ~~$390,000,~~ and $~~500~~264,000 for the years ended December 31, ~~2016,~~2017 ~~2015,~~ and ~~2014~~2016, respectively. ~~During the year ended December 31, 2014, royalty expense reported in discontinued operations was approximately $1,000.~~

We will continue to be obligated for royalty payments in the future associated with the shipment and licensing of certain of our products. While we are currently unable to estimate the maximum amount of these future royalties, such amounts will continue to be dependent on the number of units shipped or the amount of revenue generated from these products.

Taxes. We conduct our operations in many tax jurisdictions throughout the world. In many of these jurisdictions, non-income based taxes such as property taxes, sales and use taxes, and value-added taxes are assessed on Echelon’s operations in that particular location. While we strive to ensure compliance with these various non-income based tax filing requirements, there have been instances where potential non-compliance exposures have been identified. In accordance with generally accepted accounting principles, we make a provision for these exposures when it is both probable that a liability has been incurred and the amount of the exposure can be reasonably estimated. To date, such provisions have been immaterial, and we believe that, as of December 31, ~~2016~~2017, we have adequately provided for such contingencies. However, it is possible that our results of operations, cash flows, and financial position could be harmed if one or more non-compliance tax exposures are asserted by any of the jurisdictions where we conduct our operations.

Legal Actions. From time to time, in the ordinary course of business, we may be subject to other legal proceedings, claims, investigations, and other proceedings, including claims of alleged infringement of third-party patents and other intellectual property rights, and commercial, employment, and other matters. In accordance with generally accepted accounting principles, we make a provision for a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case. While we believe we have adequately provided for such contingencies as of December 31, 2016, the amounts of which were immaterial, it is possible that our results of operations, cash flows, and financial position could be harmed by the resolution of any such outstanding claims.

~~As of December 31, 2016, our contractual obligations were as follows (in thousands):~~34

	Payments due by period
	Total		Less than 1 year		2-3 years		4-5 years		More than 5 years

we have adequately provided for such contingencies as of December 31, 2017, the amounts of which were immaterial, it is possible that our results of operations, cash flows, and financial position could be harmed by the resolution of any such outstanding claims.

The amounts in the table above exclude $426,000 of income tax liabilities and related interest and penalties related to uncertain tax positions as we are unable to reasonably estimate the timing of settlement. See Note 12 - Income Taxes of Notes to Consolidated Financial Statements for further discussion.

LIQUIDITY AND CAPITAL RESOURCES

Since our inception, we have financed our operations and met our capital expenditure requirements primarily from the sale of preferred stock and common stock, although during 2012 and certain earlier years, we were also able to finance our operations through operating cash flow.

The following table presents selected financial information as of December 31, ~~2016,~~2017 and ~~for~~2016 ~~each of the last three fiscal years~~ (dollars in thousands):

	December 31,
	2016		2015		2014
	2017		2016
Cash, cash equivalents, restricted investments, and short-term investments	$	2320,~~036~~478	$	2623,~~070~~036	$	~~43,570~~

Stockholders’ equity	$	2421,~~678~~887	$	2824,~~921~~678	$	~~43,177~~

As of December 31, ~~2016~~2017, we had $2320.05 million in cash, cash equivalents, restricted investments, and short-term investments, a decrease of $32.06 million as compared to December 31, ~~2015~~2016. Historically, our primary source of cash, other than stock sales, has been receipts from revenue, and to a lesser extent, proceeds from the exercise of stock options and warrants by our employees and directors. Our primary uses of cash have been cost of product revenue, payroll (salaries, commissions, bonuses, and benefits), general operating expenses (costs associated with our offices such as rent, utilities, and maintenance; fees paid to third party service providers such as consultants, accountants, and attorneys; travel and entertainment; equipment and supplies; advertising; and other miscellaneous expenses), acquisitions, capital expenditures, payment of taxes associated with certain equity compensation awards, purchases under our stock repurchase programs, and early termination charges associated with our operating leases.

Cash flows from operating activities. Cash flows from operating activities have historically been driven by net income (loss) levels; adjustments for non-cash charges such as impairment charges, write-downs of property, plant, and equipment, stock-based compensation, depreciation and amortization, and changes in accrued investment income; and fluctuations in operating asset and liability balances. Net cash used in operating activities was $32.02 million for the year ended December 31, ~~2016~~2017, a decrease in cash outflows of approximately $~~1.9 million~~798,000 as compared to ~~2015~~2016. During the year ended December 31, ~~2016~~2017, net cash used in operating activities was primarily the result of our net loss of $4.16 million, ~~and a reduction in the amount of contingent consideration we owed the former Lumewave shareholders; all of~~ which was partially offset by stock-based compensation expenses of $~~746~~1.5 million,~~000,~~ depreciation and amortization expense of $~~489~~454,000, and changes in our operating assets and liabilities of $~~199~~600,000. The primary components of the $~~199~~600,000 net change in our operating assets and liabilities were a $1.0 million increase in ~~accounts~~deferred ~~receivable~~revenues, a $~~340~~586,000 increase in ~~deferred~~accounts ~~revenues~~payable, ~~a $323,000 decrease in inventories,~~ and a $~~200~~367,000 decrease in ~~other~~accounts ~~current assets~~receivable; all of which was partially offset by a $~~1.2 million~~681,000 ~~decrease~~increase in ~~accrued~~inventories ~~liabilities~~ and ana $~~558~~628,000 ~~decrease~~increase in ~~accounts~~deferred ~~payable.~~cost ~~Accounts receivable increased based on the timing~~ of ~~shipments~~goods ~~in the fourth quarter of 2016~~sold.

Net cash used in operating activities was $43.90 million for the year ended December 31, ~~2015~~2016, a decrease in cash outflows of approximately $6.1.9 million as compared to ~~2014~~2015. During the year ended December 31, ~~2015~~2016, net cash used in operating activities was primarily the result of our net loss ~~(including non-controlling interest)~~ of $134.21 million~~, changes~~ ~~in our operating assets~~ and ~~liabilities of $2.2 million, and~~ a reduction in ~~expected~~the amount of contingent consideration we ~~will~~owed ~~owe~~ the former Lumewave shareholders; all of which was partially offset by ~~the non~~stock-~~cash~~based ~~goodwill~~compensation ~~impairment~~expenses ~~charge~~ of $~~5.7 million~~746, ~~lease termination charges of $3.3 million~~000, depreciation and amortization expense of $~~1.8 million~~489, ~~stock-based compensation expenses of $293,~~000, and ~~losses~~changes onin ~~disposals~~our ~~and~~operating ~~write-downs~~assets ofand ~~fixed~~liabilities ~~assets~~ of $81199,000.

Other current assets decreased primarily as a result of a reduction in prepaid expenses and the refund of the deposit on our old headquarters building in San Jose.

Cash flows from investing activities. Cash flows from investing activities have historically been driven by transactions involving our short-term investment portfolio, capital expenditures, changes in our long-term assets, and acquisitions and divestitures. Net cash used in ~~operating~~investing activities was $~~11.0 million~~182,000 for the year ended December 31, ~~2014~~2017, an increase ~~in cash outflows~~ of ~~approximately~~ $95.94 million asin cash outflows compared to ~~2013~~2016. During the year ended December 31, ~~2014~~2017, net cash used ininvesting ~~operating~~ activities was primarily the result of ~~our~~purchases ~~net loss (including non-controlling interest)~~ of ~~$24.9 million, partly offset by changes in operating assets and liabilities of $513,000, non~~available-~~cash charges~~ for ~~losses on disposals and write~~-~~downs~~sale ~~of fixed assets of $5.2 million, depreciation and amortization expense of $3.4 million, goodwill impairment charges of $3.4 million, stock~~short-~~based~~term ~~compensation~~investments ~~expenses~~ of $123.29 million, ~~and~~capital ~~the~~expenditures ~~loss we recorded on the sale~~ of ~~our Grid division of~~ $~~254~~209,000~~. The primary components of the $513~~,~~000~~ ~~net change in our operating assets~~ and ~~liabilities~~changes ~~were a $2.5 million decrease~~ in ~~accounts receivable, a $1.8 million decrease in inventories, a $1.0 million decrease in~~ other ~~current~~long-term assets, ~~and~~of a $~~209~~98,000; ~~decrease~~all ~~in deferred cost~~ of ~~goods~~which ~~sold,~~was partially offset by aproceeds afrom ~~$4.0 million decrease in accrued liabilities, an $846,000 decrease in deferred revenues, and an $81,000 decrease in accounts payable.

Net cash used in financing activities was $8.7 million for the year ended December 31, 2014, an increase in outflows of $6.2 million as compared to the same period in 2013. During the year ended December 31, 2014, net cash used in financing activities was primarily the result of $6.3 million in purchases of restricted investments, $2.1 million in principal payments on

our building lease financing obligations and $422,000 worth of shares repurchased from employees for payment of employee taxes on vesting of restricted stock units and upon exercise of stock options.

As noted above, our cash and investments totaled $23.0 million as of December 31, 2016. Of this amount, approximately 5% was held by our foreign subsidiaries. Our intent is to permanently reinvest a significant portion of our earnings from foreign operations, and current plans do not anticipate that we will need funds generated from foreign operations to fund our domestic operations. In the event funds from foreign operations are needed to fund operations in the United States and if U.S. tax has not already been previously provided, we would provide for and pay any additional U.S. taxes due in connection with repatriating these funds.

We use well-regarded investment managers to manage our invested cash. Our portfolio of investments managed by these investment managers is primarily composed of highly rated U.S. government securities, and to a lesser extent, money market funds. All investments are made according to guidelines and within compliance of policies approved by the Audit Committee of our Board of Directors.

Until December 2014, we maintained a $5.0 million line of credit with our primary bank. The line of credit was secured by a collateral of the first priority on $6.3 million of our investments placed in a separate account. In December 2014, we cancelled this line of credit. We ~~continue~~currently to maintain an operating credit line of $1.0 million with our primary bank for company credit card purchases. This line of credit continues to be secured by a collateral of the first priority on $1.3 million of our investments (presented as restricted investments in the Consolidated Balance Sheets).

On August 15, 2014, we purchased 100% of the outstanding shares of Lumewave, Inc. (“Lumewave”). The acquisition was aimed at expanding our street lighting business. The purchase price consisted of $1.8 million in cash paid at closing and $715,000 in shares of our common stock distributed at closing.

In the future, our cash reserves may be used to strategically acquire other companies, products, or technologies that are complementary to our business or for settlements of customer disputes or litigation. In addition, our combined cash, cash equivalents, and short-term investments balances could be negatively affected by various risks and uncertainties, including, but not limited to, the risks detailed in this Annual Report in Part I, Item 1A - Risk Factors. For example, any continued weakening of economic conditions or changes in our planned cash outlay could negatively affect our existing cash reserves.

Based on our current business plan and revenue prospects, we believe that our existing cash reserves will be sufficient to meet our projected working capital and other cash requirements for at least the next twelve months. However, we currently expect that our combined cash, cash equivalent, restricted investments, and short-term investment balance will decline during 2017. In the event that we require additional financing, such financing may not be available to us in the amounts or at the times that we require, or on acceptable terms. If we fail to obtain additional financing, when and if necessary, our business would be harmed.36

RELATED PARTY TRANSACTIONS

In June 2000, we entered into a stock purchase agreement with Enel pursuant to which Enel purchased 300,000 newly issued shares of our common stock for $130.7 million. The closing of this stock purchase occurred on September 11, 2000. At the closing, Enel had agreed that it would not, except under limited circumstances, sell or otherwise transfer any of those shares for a specified time period. That time period expired September 11, 2003. To our knowledge, Enel has not disposed of any of its 300,000 shares. Under the terms of the stock purchase agreement, Enel has the right to nominate a member of our board of directors. A representative of Enel served on our board until March 14, 2012; no Enel representative is presently serving on our board.

At the time the company entered into the stock purchase agreement with Enel, it also entered into a research and development agreement with an affiliate of Enel (the “R&D Agreement”). Under the terms of the R&D Agreement, the company cooperated with Enel to integrate its LONWORKS technology into Enel’s remote metering management project in Italy, the Contatore Elettronico. The company completed the sale of its components and products for the deployment phase of the Contatore Elettronico project during 2005. During 2006, the company supplied Enel and its designated manufacturers with limited spare parts for the Contatore Elettronico system. In October 2006, the company entered into a new development and supply agreement and a software enhancement agreement with Enel. Under the development and supply agreement, Enel and its contract manufacturers purchase additional electronic components and finished goods from the company. Under the software enhancement agreement, the company provided software enhancements to Enel for use in its Contatore Elettronico system. The software enhancement was assigned to S&T as part of the sale of our Grid division in September 2014. The development and supply agreement expired in March 2016, although delivery of products can extend beyond then and the agreement may be extended under certain circumstances.

43We recognized no revenue from Enel during the year ended December 31, 2017. During the year ended December 31, 2016, we recognized revenue from products and services sold to Enel and its designated manufacturers of approximately $1.3 million. As of December 31, 2017 and 2016, none of the Company’s total accounts receivable balance related to amounts owed by Enel and its designated manufacturers.

supply agreement expired in December 2015, although delivery of products can extend beyond then and the agreement may be extended under certain circumstances.

For the years ended December 31, 2016, 2015, and 2014, we recognized revenue from products and services sold to Enel and its designated manufacturers of approximately $1.3 million, $4.9 million, and $3.0 million, respectively. As of December 31, 2016 and 2015, $0 and $827,000 of the Company’s total accounts receivable balance related to amounts owed by Enel and its designated manufacturers, respectively.

RECENTLY ISSUED ACCOUNTING STANDARDS

During ~~2016~~2017, there have been no new recent accounting pronouncements or changes in accounting pronouncements, other than those noted in Note 1 in the Notes to Consolidated Financial Statements in Part IV, Item 15 of this report, that are of significance, or potential significance, to our company.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS

Market Risk Disclosures. The following discussion about our market risk disclosures involves forward-looking statements. Actual results could differ materially from those projected in the forward-looking statements. We are exposed to market risk related to changes in interest rates and foreign currency exchange rates. We do not use derivative financial instruments to hedge these exposures.

Interest Rate Sensitivity. We maintain a short-term investment portfolio consisting mainly of fixed income securities with a weighted average maturity of less than one year. These available-for-sale securities are subject to interest rate risk and will fall in value if market interest rates increase. If market rates were to increase immediately and uniformly by 10% from levels at December 31, ~~2016~~2017 and December 31, ~~2015~~2016, the fair value of the portfolio would decline by an immaterial amount. We currently intend to hold our fixed income investments until maturity, and therefore we would not expect our operating results or cash flows to be affected to any significant degree by a sudden change in market interest rates. However, if necessary, we may sell short-term investments prior to maturity to meet the liquidity needs of the company.

Foreign Currency Exchange Risk. We have international subsidiaries and operations and are, therefore, subject to foreign currency rate exposure. To date, our exposure to exchange rate volatility has not been significant. If foreign exchange rates were to fluctuate by 10% from rates at December 31, 2016, and December 31, 2015, our financial position and results of operations would not be materially affected. However, we could experience a material impact in the future.

were to fluctuate by 10% from rates at December 31, 2017, and December 31, 2016, our financial position and results of operations would not be materially affected. However, we could experience a material impact in the future.

In addition, for our cost of goods sold, our products are generally assembled by CEMs in China, although our transactions with these vendors have historically been denominated in U.S. dollars. These vendors may require us to pay in their local currency, or demand a U.S. dollar price adjustment or other payment to address a change in exchange rates, which would increase our cost to procure our products. This is particularly a risk in China, where any future revaluations of the Chinese currency against the U.S. dollar could result in significant cost increases.

ITEM 9A. CONTROLS AND PROCEDURES


a.	Evaluation of Effectiveness of Disclosure Controls and Procedures

We have designed our disclosure controls and procedures to ensure that information we are required to disclose in reports that we file or submit under the Securities and Exchange Act of 1934 is accumulated and communicated to our management, including our principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure, and that such information is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms. As of the end of the period covered by this Annual Report on Form 10-K, under the supervision of our Chief Executive Officer and our Chief Financial Officer, we evaluated the effectiveness of our disclosure controls and procedures, as such terms are defined in Rule 13a-15(e) and Rule 15d-15(e) under the Securities and Exchange Act of 1934. Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of December 31, 2017.

supervision of our Chief Executive Officer and our Chief Financial Officer, we evaluated the effectiveness of our disclosure controls and procedures, as such terms are defined in Rule 13a-15(e) and Rule 15d-15(e) under the Securities and Exchange Act of 1934. Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of December 31, 2016.


b.	Management's Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934). Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, ~~2016~~2017. This evaluation was based on the framework in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control - Integrated Framework (1992), our management concluded that our internal control over financial reporting is effective at this reasonable assurance level as of December 31, ~~2016~~2017.


c.	Changes in Internal Control Over Financial Reporting

There were no changes in our internal controls over financial reporting (as defined in Rule 13a-15(e) of the Exchange Act) that occurred during the quarter ended December 31, ~~2016~~2017, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

ECHELON CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Significant Accounting Policies

Operations

Echelon Corporation (the Company) was incorporated in California in February 1988 and reincorporated in Delaware in January 1989. The Company is based in Santa Clara, California, and maintains offices in ~~seven~~six foreign countries throughout Europe and Asia. Its products enable everyday devices — such as air conditioners, appliances, elevators, electricity meters, light switches, thermostats, and valves — to be made “smart” and inter-connected, part of an emerging market known as the Industrial Internet of Things ("IIoT").

Its proven, open standard, multi-application energy control networking platform powers applications for smart cities, smart buildings, and smart campuses that help customers save on their energy usage, reduce outage duration or prevent them from happening entirely, reduce carbon footprint and more. Today, the Company offers, directly and through its partners worldwide, a wide range of products and services.

Basis of Presentation

The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries, and a subsidiary in which it has a controlling interest (collectively referred to as the “Company”). The Company reports noncontrolling interests in consolidated entities as a component of equity separate from the Company’s equity. All material inter-company transactions between and among the Company and its consolidated subsidiaries and other consolidated entities have been eliminated in consolidation.

In 2014, the Company announced and completed the sale of its Grid business to S&T AG, a publicly traded European IT systems provider with an existing focus on smart energy products and services. The results of the Grid business for the year ended December 31, 2014, is now classified as discontinued operations. As a result of this transaction, the Company now operates in one reporting segment- the IIoT segment.

Risks and Uncertainties

The Company’s operations and performance depend significantly on worldwide economic conditions and their impact on purchases of the Company’s products, as well as the ability of suppliers to provide the Company with products and services in a timely manner. The impact of any of the matters described below could have an adverse effect on the Company’s business, results of operations and financial condition.

• The Company's sales are currently concentrated, as approximately 28.70% of revenues for the year ended December 31, ~~2016~~2017, were derived from one customer, Avnet Europe Comm VA ("Avnet"), the Company's primary distributor of its IIoT products in Europe and Japan. Customers in any of the Company’s target market sectors may experience unexpected reductions in demand for their products and consequently reduce their purchases from the Company, resulting in either the loss of a significant customer or a notable decrease in the level of sales to a significant customer. In addition, if any of these customers are unable to obtain the necessary capital to operate their business, they may be unable to satisfy their payment obligations to the Company.


•	The Company utilizes third-party contract electronic manufacturers to manufacture, assemble, and test its products. If any of these third-parties were unable to obtain the necessary capital to operate their business, they may be unable to provide the Company with timely services or to make timely deliveries of products.

•

From time to time, the Company has experienced shortages or interruptions in supply for certain products or components used in the manufacture of the Company’s products that have been or will be discontinued. In order to ensure an adequate supply of these items, the Company has occasionally purchased quantities of these items that are in excess of the Company’s then current estimate of short-term requirements. If the long-term requirements do not materialize as originally expected, or if the Company develops alternative solutions that no longer employ these items and the Company is not able to dispose of these excess products or components, the Company could be subject to increased levels of excess and obsolete inventories.

• Recently, in our effort to manage our costs and inventory risks, we decreased our inventory levels of certain products. If there is an unexpected increase in demand for these items, we might not be able to supply our customers with products in a timely manner.

Use of Estimates

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make judgments, assumptions, and estimates that affect amounts reported in the Consolidated Financial Statements and accompanying notes. Significant estimates and judgments are used for revenue recognition, performance-based equity compensation, inventory valuation, intangible asset valuation, goodwill valuation, contingent consideration valuation, and other loss contingencies. In order to determine the carrying values of assets and liabilities that are not readily apparent from other sources, the Company bases its estimates and assumptions on current facts, historical experience, and various other factors that it believes to be reasonable under the circumstances. Actual results experienced by the Company may differ materially from management’s estimates.

Recently Issued Accounting Standards

(i) New Accounting Standards Recently Adopted

In July 2015, the FASB issued an update to ASC 330, Inventory: Simplifying the Measurement of Inventory. Under this update, subsequent measurement of inventory is based on the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less the estimated cost of completion and disposal. This update does not apply to inventory that is measured using last-in, first-out or the retail inventory method. This update was adopted by the Company in the first quarter of fiscal year 2017 and did not have a significant impact on its consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718), which simplifies the accounting for share-based payments, including income tax consequences, accounting for forfeitures, classification of awards as either equity or liabilities, and classification on the statements of cash flows. This guidance is effective for interim and annual periods beginning after December 15, 2016, with early adoption permitted. During the fourth quarter of 2016, the Company elected to early adopt ASU 2016-09, with retrospective application to January 1, 2016. The primary impact of adoption was to the Company's accounting policy for forfeited equity compensation awards. Prior to the adoption of ASU 2016-09, the Company's stock-based compensation expense was calculated using an estimated forfeiture rate. Following the adoption, the Company recognizes the impact of forfeitures on stock-based compensation expense as they occur. The net cumulative effect of this change was recognized as a $675,000 reduction to retained earnings as of January 1, 2016.

(ii) New Accounting Standards Not Yet Effective

On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In July 2015, the FASB deferred the effective date of ASU 2014-09 so that it will apply to annual reporting periods beginning after December 15, 2017 (including interim reporting periods within those periods). Early application is permitted to annual reporting periods beginning after December 15, 2016, in which case ASU 2014-09 would apply to annual reporting periods beginning after December 15, 2016 (including interim reporting periods within those periods). The standard permits the use of either the retrospective or cumulative effect transition method. The Company has not yet selected a transition method. The Company currently anticipates the standard will have a material impact on its financial statements and disclosures. While the Company continues to assess all potential impacts of the standard, it currently believes the most significant impact relates to its accounting for sales made to distributors under agreements that contain a limited right to return unsold products and price adjustment provisions. Under the existing revenue guidance, the Company has historically concluded that the price to these distributors is not fixed or determinable at the time it delivers products to them. Accordingly, revenue from sales to these distributors has not historically been recognized until the distributor resells the product. By contrast, under the new standard, the Company expects to recognize revenue, including estimates for applicable variable consideration, predominately at the time of shipment to these distributors, thereby accelerating the timing of revenue for products sold through distributors. During the year ended December 31, 2016, the Company recognized approximately $14.7 million of revenue sold through such distributors.

In July 2015, the FASB issued an update to ASC 330, Inventory: Simplifying the Measurement of Inventory. Under this update, subsequent measurement of inventory is based on the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less the estimated cost of completion and disposal. This update does not apply to inventory that is measured using last-in, first-out or the retail inventory method. This update should be applied prospectively and will be adopted by the Company in the first quarter of fiscal year 2017. Early adoption is permitted. The Company does not believe the adoption will have a significant impact on its consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires, among other things, the recognition of lease assets and lease liabilities on the balance sheet by lessees for certain leases classified as operating leases under previous GAAP. ASU 2016-02 is effective for annual and interim periods beginning after December 15, 2018. ASU 2016-02 mandates a modified retrospective transition method with early adoption permitted. The Company is currently evaluating the effect that ASU 2016-02 will have on its consolidated financial statements and related disclosures.

58In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which superseded existing revenue recognition guidance under current U.S. GAAP. The standard is a comprehensive revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. In doing so, among other things, companies will generally need to use more judgment and make more estimates than under the current guidance. Recently, the FASB has issued guidance clarifying certain topics such as (i) gross versus net revenue reporting, (ii) identifying performance obligations and licensing, (iii) accounting for shipping and handling fees and costs, and (iv) accounting for consideration given by a vendor to a customer.

~~Revenue~~The ~~Recognition~~standard will be effective for Echelon in the fiscal year beginning January 1, 2018. The standard permits two methods of adoption: (i) retrospectively to each prior reporting period presented (the full retrospective method), or (ii) retrospectively with the cumulative effect of initially applying the standard recognized at the date of initial application (the cumulative catch-up transition method). The Company will adopt the standard using the full retrospective method to restate each prior reporting period presented.

In preparation for the adoption, the Company has implemented internal controls to enable the preparation of financial information and has reached conclusions on key accounting assessments related to the standard. The Company currently believes the most significant impact of adopting the new standard will relate to its accounting for sales made to distributors under agreements that contain a limited right to return unsold products and price adjustment provisions. Under the existing revenue guidance, the Company has historically concluded that the price to these distributors is not fixed or determinable at the time it delivers products to them. Accordingly, revenue from sales to these distributors has not historically been recognized until the distributor resells the product. By contrast, under the new standard, the Company will recognize revenue, including estimates for applicable variable consideration, predominately at the time of shipment to these distributors, thereby accelerating the timing of revenue for products sold through the distribution channel. The Company does not currently capitalize costs to obtain customer contracts such as commission expenses, nor does it expect to capitalize such costs under the new standard.

Adoption of the standard will result in the recognition of additional revenue of $274,000 for the year ended December 31, 2017. In addition, adoption of the standard will result in a reduction of deferred revenues of $3.0 million as of December 31, 2017, driven by the recognition of revenues associated with on-hand distributor inventory as of that date, the revenue for which was deferred under previous guidance; a decrease of deferred cost of goods sold of $728,000 as of December 31, 2017, again driven by the recognition of revenue that was deferred under previous guidance; and a decrease in accounts receivable of $395,000 as of December 31, 2017, driven by the incremental reserves required for estimated price adjustments that will be

issued to the distributors in the future based on the additional revenue recognized under the new guidance. See Expected Impacts to Reported Results below for the impact of adoption of the standard on our consolidated financial statements.

Current Revenue Recognition

The Company’s revenues are derived from the sale and license of its products and to a lesser extent, from fees associated with training, technical support, and custom software design services offered to its customers. Product revenues consist of revenues from hardware sales and software licensing arrangements. Service revenues consist of product technical support (including software post-contract support services), training, and custom software development services.

The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery to the customer’s carrier (and acceptance, as applicable) has occurred, the sales price is fixed or determinable, collectability is probable, and there are no post-delivery obligations. For non-distributor hardware sales, including sales to third party manufacturers, these criteria are generally met at the time of delivery to the customer’s carrier. However, for arrangements that contain contractual acceptance provisions, revenue recognition may be delayed until acceptance by the customer or the acceptance provisions lapse unless the Company can objectively demonstrate that the contractual acceptance criteria have been satisfied, which is generally accomplished by establishing a history of acceptance for the same or similar products. For sales made to the Company’s distributor partners, revenue recognition criteria are generally met at the time the distributor sells the products through to its end-use customer. Service revenue is recognized as the training services are performed, or ratably over the term of the support period.

The Company accounts for the rights of return, price protection, rebates, and other sales incentives offered to distributors of its products as a reduction in revenue. With the exception of sales to distributors, the Company’s customers are generally not entitled to return products for a refund. For sales to certain distributors, due to contractual rights of return and other factors that impact its ability to make a reasonable estimate of future returns and other sales incentives, revenues are not recognized until the distributor has shipped its products to the end customer.

The Company’s multiple deliverable revenue arrangements have historically been primarily related to sales of its Grid products. As noted above, the Company completed the sale of its Grid division to S&T AG in September 2014. Therefore, multiple element arrangements are now limited. These historical transactions typically included, within a single arrangement, a combination of some or all of the following deliverables: electricity meters, data concentrators and related hardware (collectively, the “Hardware”); NES system software; Element Manager software; post-contract customer support (“PCS”) for the NES system and Element Manager software; extended warranties for the Hardware; and, occasionally, specified enhancements or upgrades to software used in the NES system. With the exception of the NES system software, each of these deliverables was considered a separate unit of accounting. The NES system software functions together with an electricity meter to deliver its essential functionality and any related software license fee is charged for on a per meter basis. Therefore, the NES system software and an electricity meter are combined and considered a single unit of accounting. The Element Manager software is not considered to be part of an electricity meter’s essential functionality and, therefore, Element Manager software and any related PCS has been accounted for under industry specific software revenue recognition guidance. However, all other NES system deliverables are no longer within the scope of industry specific software revenue recognition guidance.52

The Company allocates revenue to each element in a multiple-element arrangement based upon their relative selling price. The Company determines the selling price for each deliverable using vendor specific objective evidence (“VSOE”) of selling price or third party evidence (“TPE”) of selling price, if it exists. If neither VSOE nor TPE of selling price exists for a deliverable, the Company uses its best estimated selling price (“BESP”) for that deliverable. Any discounts offered by the Company are allocated, proportionally, to each of the deliverables. Revenue allocated to each element is then recognized when the basic revenue recognition criteria is met for the respective element.

If available, the Company determines VSOE of fair value for each element based on historical stand-alone sales to third parties or from the stated renewal rate for the elements contained in the initial contractual arrangement. The Company currently estimates selling prices for its PCS and extended warranties based on VSOE of fair value.

In many instances, the Company is not currently able to obtain VSOE of fair value for all deliverables in an arrangement with multiple elements. This may be due to the Company infrequently selling each element separately or not pricing products within a narrow range. When VSOE cannot be established, the Company attempts to estimate the selling price of each element based on TPE. TPE would consist of competitor prices for similar deliverables when sold separately. Generally, the Company’s offerings contain significant differentiation such that the comparable pricing of products with similar functionality cannot be obtained. Furthermore, the Company is unable to reliably determine the stand-alone selling prices for similar products of its competitors. Therefore, the Company is typically not able to obtain TPE of selling price.

When the Company is unable to establish a selling price using VSOE or TPE, which was generally the case for the Hardware and certain specified enhancements or upgrades to the Company’s NES software, the Company uses its BESP in determining the allocation of arrangement consideration. The objective of BESP is to determine the price at which the

Company would transact a sale if the product or service were sold on a stand-alone basis. BESP is generally used for offerings that are not typically sold on a stand-alone basis or for new or highly customized offerings.

The Company establishes pricing for its products and services by considering multiple factors including, but not limited to, geographies, market conditions, competitive landscape, internal costs, gross margin objectives, and industry pricing practices. The determination of pricing also includes consultation with and formal approval by the Company’s management, taking into consideration the Company’s go-to-market strategy. These pricing practices apply to both the Company’s Hardware and software products.

Based on an analysis of pricing stated in contractual arrangements for its Hardware products in historical multiple-element transactions and, to a lesser extent, historical standalone transactions, the Company has concluded that it typically prices its Hardware within a narrow range of discounts when compared to the price listed on the Company’s standard pricing grid for similar deliverables (i.e., similar configuration, volume, geography, etc.). Therefore, the Company has determined that, for its current Hardware for which VSOE or TPE is not available, the Company’s BESP is generally comprised of prices based on a narrow range of discounts from pricing stated in its pricing grid.

When establishing BESP for the Company’s specified software enhancements or upgrades, the Company considers multiple factors including, but not limited to, the relative value of the features and functionality being delivered by the enhancement or upgrade as compared to the value of the software product to which the enhancement or upgrade relates, as well as the Company’s pricing practices for NES system software PCS packages, which may include rights to the specified enhancements or upgrades.

The Company regularly reviews VSOE and has established a review process for TPE and BESP. The Company maintains internal controls over the establishment and updates of these estimates. There were no material impacts during the year ended December 31, 2016, resulting from changes in VSOE, TPE, or BESP, nor does the Company expect a material impact from such changes in the near term.

Deferred Revenue and Deferred Cost of Goods Sold

Deferred revenue consists substantially of amounts billed or payments received in advance of revenue recognition. Deferred cost of goods sold related to deferred product revenues includes direct product costs and applied overhead. Once all revenue recognition criteria have been met, the deferred revenues and associated cost of goods sold are recognized.

Stock-Based Compensation

The Company accounts for employee stock-based payment transactions in which the Company receives employee services in exchange for equity instruments of the enterprise. Stock-based compensation cost for restricted stock units (“RSUs”) granted to employees is measured based on the closing fair market value of the Company's common stock on the date of grant. Stock-based compensation cost for RSUs granted to non-employee consultants is measured based on the closing fair market value of the Company's common stock at the earlier of the date at which a commitment for performance by the consultant to earn the RSUs is reached, or the date at which the consultant's performance necessary for the RSUs to vest has been completed. Stock-based compensation cost for stock options ~~and stock appreciation rights~~ granted to employees ~~(“SARs”)~~ is estimated at the grant date based on each award's fair-value as calculated using the Black-Scholes-Merton (“BSM”) option-pricing model. The Company recognizes stock-based compensation cost as expense using the accelerated multiple-option approach over the requisite service period. Further information regarding stock-based compensation can be found in Note 87 of these Notes to Consolidated Financial Statements.

Cash and Cash Equivalents

The Company considers bank deposits, money market investments and all debt and equity securities with remaining maturities of three months or less at the date of purchase to be cash and cash equivalents.

Short-Term Investments

The Company classifies its investments in marketable debt securities as available-for-sale. Securities classified as available-for-sale are reported at fair value with the related unrealized holding gains and losses, net of tax, being included in accumulated other comprehensive loss.

Fair Value Measurements

The Company measures at fair value its cash equivalents and available-for-sale investments using a valuation hierarchy based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company's own assumptions. These two types of inputs have created the following fair value hierarchy:

data obtained from independent sources, while unobservable inputs reflect the Company's own assumptions. These two types of inputs have created the following fair value hierarchy:


•	Level 1 - Quoted prices for identical instruments in active markets;


•	Level 2 - Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and


•	Level 3 - Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

This hierarchy requires the Company to minimize the use of unobservable inputs and to use observable market data, if available, when estimating fair value. Other than cash and money market funds, the Company's only financial assets or liabilities required to be measured at fair value on a recurring basis at December 31, ~~2016~~2017, are fixed income available-for-sale securities. See Note 2 of these Notes to Consolidated Financial Statements for a summary of the input levels used in determining the fair value of the Company's cash equivalents and short-term investments as of December 31, 2017 and 2016.

Inventories

Inventories are stated at the lower of cost (first‑in, first‑out) or ~~market~~net realizable value and include material, labor and manufacturing overhead. When required, provisions are made to reduce excess and obsolete inventories to their estimated net realizable value. Inventories consist of the following (in thousands):

Purchased materials	$	148	$	164
Finished goods	2,422		2,729

~~The~~Impairment ~~Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount~~ of ~~an asset may not be recoverable. Recoverability is measured by comparing the asset's carrying value to the future undiscounted cash flows the asset is expected to generate. If long~~Long-~~lived~~Lived ~~assets~~Assets are considered to be impaired, the impairment to be recognized equals the amount by which the carrying value of the asset exceeds its fair value. For the year ended December 31, 2014, the Company recognized impairments associated with certain long-lived assets associated with its Grid division and a building that the Company ceased use of at its corporate headquarters facility (see Note 3 for additional information regarding the impairment). For the years ended December 31, 2016 and December 31, 2015, the Company recognized no impairments of long-lived assets.

~~Costs~~The inCompany ~~excess~~reviews oflong-lived ~~the fair value of tangible and other identifiable intangible~~ assets ~~acquired and liabilities assumed in a purchase business combination are recorded as goodwill, which is tested~~ for impairment ~~using a two-step approach.

Software Development Costs

For software to be sold, leased, or otherwise marketed, the Company capitalizes eligible computer software development costs upon the establishment of technological feasibility, which the Company has defined as completion of a working model. For the ~~three~~two years ended December 31, ~~2016~~2017, costs that were eligible for capitalization were insignificant and, thus, the Company has charged all software development costs to product development expense in the accompanying consolidated statements of operations.

Accrued Liabilities

Accrued liabilities consist of the following (in thousands):

Foreign Currency Translation

The functional currency of the Company's subsidiaries is the local currency. Accordingly, all assets and liabilities are translated into U.S. dollars at the current exchange rate as of the applicable balance sheet date. Equity transactions are translated using historical exchange rates. Revenues and expenses are translated at the average exchange rate prevailing during the period. Gains and losses resulting from the translation of the financial statements are included in accumulated other comprehensive income (loss).

Remeasurement adjustments for non-functional currency monetary assets and liabilities, including short-term intercompany balances, are included in other income (expense) in the accompanying consolidated statements of operations. Currently, the Company does not employ a foreign currency hedge program utilizing foreign currency exchange contracts as the foreign currency transactions and risks to date have not been significant.

Concentrations of Credit Risk and Suppliers

The Company's financial instruments have historically consisted of cash equivalents, short-term investments, accounts receivable, accounts payable, and lease financing obligations. The carrying value of the Company's financial instruments approximates fair value. Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of investments, which are classified as either cash equivalents or short-term investments, and trade receivables. With respect to its investments, the Company has an investment policy that limits the amount of credit exposure to any one financial institution and restricts placement of the Company's investments to financial institutions independently evaluated as highly creditworthy. With respect to its trade receivables, the Company performs ongoing credit evaluations of each of its customers' financial condition. For a customer whose credit worthiness does not meet the Company's minimum criteria, the Company may require partial or full payment prior to shipment. Alternatively, prior to shipment, customers may be required to provide the Company with an irrevocable letter of credit or arrange for some other form of coverage, such as a bank guarantee, to mitigate the risk of uncollectibility. Additionally, the Company establishes an allowance for doubtful accounts and sales return allowances based upon factors surrounding the credit risk of specific customers, historical trends, and other available information. With the exception of amounts owed to the Company on sales made to certain significant customers, concentrations of credit risk with respect to trade receivables are generally limited due to the Company's large number of customers and their dispersion across many different industries and geographies. As of December 31, 2016 and 2015, the percentage of the Company's total accounts receivable balance that were due from the following significant customers is as follows (refer to Note 9 - Significant Customers for a discussion of revenues generated from the Company's significant customers):

For most of the Company's products requiring assembly, it relies on a limited number of contract electronic manufacturers, principally Bel-Fuse (formerly TYCO). The Company also maintains manufacturing agreements with a limited number of semiconductor manufacturers for the production of key products.

The Neuron Chip is an important component that the Company and its customers use in control network devices. In addition to those sold by the Company, the Neuron Chip is currently manufactured and distributed only by Cypress Semiconductor. Another semiconductor supplier, STMicroelectronics, manufactures the Company's power line smart transceiver products, for which the Company has no alternative source. In addition, the Company currently purchases several key products and components from sole or limited source suppliers with which it does not maintain signed agreements that would obligate them to supply to the Company on negotiated terms.

If any of the Company's key suppliers were to stop manufacturing the Company's products or cease supplying the Company with its key components, it could be expensive and time consuming to find a replacement. There is no guarantee that the Company would be able to find acceptable alternatives or additional sources.

The failure of any key manufacturer to produce a sufficient number of products on time, at agreed quality levels, and fully compliant with the Company's product, assembly and test specifications could adversely affect the Company's revenues and gross profit, and could result in claims against the Company by its customers, which could harm the Company's results of operations and financial position.

Computation of Basic and Diluted Net Loss Per Share

Basic net loss per share is calculated by dividing net loss attributable to Echelon Corporation Stockholders by the weighted average shares of common stock outstanding during the period. Diluted net loss per share attributable to Echelon Corporation Stockholders is calculated by adjusting the weighted average number of outstanding shares assuming conversion of all potentially dilutive stock options and warrants under the treasury stock method.

For the years ended December 31, 2016, 2015 and 2014, the diluted net loss per share calculation is equivalent to the basic net loss per share calculation as there were no potentially dilutive stock options or RSUs due to the Company’s net loss position. The number of stock options, stock appreciation rights, restricted stock units (“RSUs”), restricted stock awards (“RSAs”), and contingently issuable shares excluded from this calculation for the years ended December 31, 2016, 2015 and 2014 was 837,035, 367,363 and 406,134, respectively.

Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred 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 tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred 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 tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

The Company takes a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the tax position will be sustained on audit, including resolution of any related appeals or litigation processes. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon effective settlement. The Company re-evaluates its income tax positions on a quarterly basis to consider factors such as changes in facts or circumstances, changes in or interpretations of tax law, effectively settled issues under audit, and new audit activity. Such a change in recognition or measurement would result in recognition of a tax benefit or an additional charge to the tax provision. Interest and penalties on unrecognized tax benefits are classified as income tax expense.

Comprehensive Income (Loss)

Comprehensive income (loss) for the Company consists of net loss plus the effect of unrealized holding gains or losses on investments classified as available-for-sale and foreign currency translation adjustments.

2. Financial Instruments

Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis

On a recurring basis, the Company measures certain of its financial assets, namely its cash equivalents, and short-term investments, ~~and measured its liability related to contingent consideration due to Lumewave, Inc. ("Lumewave") shareholders~~ at fair value. The fair value of the Company’s financial assets measured at fair value on a recurring basis was determined using the following inputs at December 31, ~~2016~~2017 (in thousands):

⁽¹⁾ Included in cash and cash equivalents in the Company’s consolidated balance sheets


⁽²⁾	Represents the portfolio of available-for-sale securities and is included in restricted investments and short-term investments in the Company’s consolidated balance sheets

The Company’s available-for-sale securities consist of U.S. government securities with a minimum and weighted average credit rating of A-1+. The Company values these securities based on pricing from pricing vendors, who may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value. However, the Company classifies all of its fixed income available-for-sale securities as having Level 2 inputs. The valuation techniques used to measure the fair value of the Company’s financial instruments having Level 2 inputs were derived from non-binding market consensus prices that are corroborated by observable market data, quoted market prices for similar instruments, or pricing models, such as discounted cash flow techniques. The Company's procedures include controls to ensure that appropriate fair values are recorded such as comparing prices obtained from multiple independent sources. There were no transfers between Level 1 and 2 hierarchies for the years ended December 31, ~~2016~~2017 and ~~2015~~2016.

As of December 31, 2017, the Company’s available-for-sale securities had contractual maturities of 6 months and an average remaining term to maturity of 3 months. Among the Company's available-for-sale securities, there have been no unrealized holding losses for a period of greater than 12 months as of December 31, 2017. As of December 31, 2017, the amortized cost basis, aggregate fair value, and gross unrealized holding gains and losses of the Company’s short-term investments by major security type were as follows (in thousands):

During the year ended December 31, 2015, the contingent consideration decreased by approximately $650,000. This decrease was comprised of a $759,000 reduction due to the Company's determination that it was no longer probable that the targets specified in the purchase agreement would be met at a level requiring full payout of the contingent consideration, and to a lesser extent, a reduction in the price of the Company's common stock. Partially offsetting this $759,000 was amortization of interest on the contingent consideration of $109,000. 56

During the quarter ended March 31, 2016, the contingent consideration decreased by approximately $318,000. This reduction was due to the Company's determination that it was no longer probable that the minimum targets specified in the purchase agreement would be met due to sales force transitions and scheduling delays for some of our larger lighting projects. Accordingly, the Company reduced the associated liability to $0 as of March 31, 2016. This resulted in a $318,000 adjustment, which was recorded as a reduction to general and administrative expenses in the Company's consolidated statements of operations.

Market values were determined for each individual security in the investment portfolio. Any decline in value of these investments is primarily related to changes in interest rates and is considered to be temporary in nature. The Company reviews its investments on a regular basis to evaluate whether or not any have experienced an other-than-temporary decline in fair value. The cost of securities sold is based on the specific identification method and realized gains and losses are included in Interest and other income (expense), net in the Company's consolidated statements of operations.

Non-Financial Assets Measured at Fair Value on a Nonrecurring Basis

The majority of the Company's non-financial assets and liabilities, which have historically included goodwill, intangible assets, inventories, and property, plant and equipment, are not required to be measured at fair value on a recurring basis. However, if certain triggering events occur (or tested at least annually for goodwill) such that a non-financial instrument is required to be evaluated for impairment and an impairment is recorded to reduce the non-financial instrument's carrying value to the fair value as a result of such triggering events, the non-financial assets and liabilities are measured at fair value for the period such triggering events occur. During the years ended December 31, 2015 and 2014, the Company recognized impairments of its goodwill of $5.7 million and $3.4 million, respectively, based on Level 1, Level 2, and Level 3 inputs. See Note 10 - Goodwill and Intangible Assets for a further discussion of these impairments.

3. Property and Equipment

A summary of property and equipment, net as of December 31, ~~2016~~2017 and ~~2015~~2016 is as follows (in thousands):

Property and equipment are stated at cost. Depreciation is provided using the straight-line method as follows:

• Computer equipment and related software, other equipment, and furniture and fixtures are depreciated over their estimated useful lives of two to five years; ~~and~~


•	Leasehold improvements are depreciated over the shorter of the remaining lease term or estimated useful lives; and


•	Certain telecommunications equipment is depreciated over its estimated useful life of 10 years.

Accounting for former San Jose headquarter buildings and improvements

In December 1999, the Company entered into a lease agreement with a real estate developer for its former corporate headquarters in San Jose, California. In October 2000, the Company entered into a second lease agreement with the same real estate developer for an additional building at its headquarters site. These leases were scheduled to expire in 2011 and 2013, respectively.

Effective June 2008, the building leases were amended resulting in an extension of the lease term for both buildings through March 2020. The extended leases required minimum lease payments through March 2020 totaling approximately $48.9 million. Both leases permitted the Company to exercise an option to extend the respective lease for 2 sequential 5-year terms. In addition, the amended leases eliminated the Company's requirement to provide the landlord with security deposits, which the Company had previously satisfied through the issuance of standby letters of credit (“LOCs”).

The Company historically accounted for the two buildings at its San Jose, California headquarters site under authoritative guidance pertaining to leases in which the Company is both involved in the construction of the lease assets and for which certain sale-leaseback criteria are not met. This results in the Company being the “deemed owner” of the two buildings for accounting purposes only. Accordingly, the leases associated with these facilities are accounted for as financing obligations.

The cost of buildings and improvements for the Company's former leased San Jose, California headquarters facilities, for which it was the “deemed owner” for accounting purposes only, included both the costs paid for directly by the Company and the costs paid for by the builder (lessor) from the period commencing with the start of construction through the lease

commencement date for each building. These building assets and leasehold improvements were depreciated over the shorter of the remaining lease term or estimated useful lives.

For the December 1999 and October 2000 lease agreements, the Company initially recorded lease financing obligations of $12.0 million and $15.2 million, respectively, which corresponded to the building asset costs paid for by the lessor. As a result of the lease extension in June 2008, the Company increased the carrying amount of its lease financing obligations by approximately $12.5 million to approximately $27.6 million (an amount equal to the present value of the revised lease payments at the date of the lease extension), with a corresponding increase to the net carrying amount of the building assets. In addition, all of the accumulated depreciation on the building assets at the date of the lease extensions was eliminated with a corresponding decrease to the gross carrying amount of the building assets. As a result of the extension in lease terms, the Company also extended the estimated useful lives of the building assets and the leasehold improvements to equal the amended lease term.

As a result of the sale of the Grid business on September 30, 2014 (see Note 5 - Discontinued Operations), the Company made the decision to cease use of one building within its corporate headquarters and recharacterize the building as a rental property. Consequently, management performed an impairment analysis on this building and determined that its carrying value was not recoverable. In performing this analysis, management analyzed the expected cash flows from different sub-lease scenarios using then current lease data for similar facilities in the area including market activity, expected tenant improvements and commissions, and period of time between recharacterization and lease up. As a result of this analysis,the Company recorded a write down of the building of $4.4 million during the three months ended September 30, 2014.

During the quarter ended June 30, 2015, the Company terminated the lease agreements for its corporate headquarter facility in San Jose, California. In conjunction with the termination of these leases and associated financing obligations, in May 2015 the Company paid an up-front lease termination charge of $10.0 million, which allowed the Company to remove approximately $15.3 million of building related financing obligations from its balance sheet. At the same time, the Company entered into a short-term lease for one of the two buildings for the remainder of 2015. As a result of the lease termination, the Company wrote the carrying value of the buildings and leasehold improvements down to its fair value, which was equal to the present value of the remaining lease payments under the short-term lease. The net effect of the lease termination transaction was a charge of $3.3 million during the quarter ended June 30, 2015.

For the years ended December 31, 2015, and 2014, the Company recorded depreciation expense associated with the former San Jose headquarter building assets of $1.1 million and $1.9 million, respectively. As of December 31, 2015, the net book value of the building assets was $0.

Under the lease agreements, a portion of the total lease payments was accounted for as an operating lease of land and recorded as expense on a straight-line basis over the term of the lease. The remaining portions of the monthly lease payments were considered to be payments of principal and interest on the lease financing obligations. For the years ended December 31, 2015, and 2014, land lease expense was $617,000 and $741,000, respectively. For the years ended December 31, 2015, and 2014, principal reductions on the lease financing obligations were $11.3 million and $2.2 million, respectively; and interest expense was $387,000 and $1.1 million, respectively.

Impairment of certain long-lived assets of the Grid business

During 2014, in light of the facts mentioned in Note 5 - Discontinued Operations and Note 10 - Goodwill and Intangible Assets, prior to assessing the goodwill for impairment, the Company evaluated whether the long-lived assets of the Grid business were impaired. As the Company had not yet made a final decision between the two likely scenarios for the Grid business as of June 30, 2014, the Company assessed the realizability of long-lived assets using cash flows associated with two scenarios for this reporting unit (i.e. sale or wind down of the Grid business). The Company applied a probability weighting of two potential scenarios: cashflows from a wind down of the business versus cashflows from a potential sale of the Grid business. The wind down scenario also included an assessment of the residual value of the Grid business’ long-lived assets. The results of this analysis showed that the carrying value of the Grid business’ long-lived assets exceeded their fair value and accordingly the Company recorded a write down of property, equipment and other assets of $687,000 during the quarter ended June 30, 2014. This impairment charge has been reported as part of the discontinued operations for the year ended December 31, 2014.

4. Acquisitions

67On August 15, 2014, the Company purchased 100% of the outstanding shares of Lumewave, Inc. (“Lumewave”). The acquisition was aimed at expanding the Company’s outdoor lighting business. The assets acquired and liabilities assumed are reflected in the Company’s consolidated balance sheet at December 31, 2017, and the results of operations of Lumewave are included in the consolidated statements of operations since August 16, 2014. The following table summarizes the purchase price allocation based on estimated fair values of assets acquired and liabilities assumed at the acquisition date (amounts in thousands):

On August 15, 2014, the Company purchased 100% of the outstanding shares of Lumewave, Inc. (“Lumewave”). The acquisition was aimed at expanding the Company’s outdoor lighting business. The purchase price consisted of $1.8 million in cash paid at closing and $715,000 in common stock of the Company distributed at closing. Additionally, if certain gross margin targets for the Lumewave business were achieved during the period from August 16, 2014 through August 15, 2016, an additional $1.3 million in consideration would have been payable to the selling shareholders of Lumewave. The fair value of this additional consideration was $925,000 as of September 30, 2014. The purchase price was subject to adjustment based on the final working capital balances. As a result of the final agreed-upon working capital balances, the selling shareholders agreed to repay $225,000, which was received by the Company during the quarter ended December 31, 2014. The cash purchase price was adjusted for this $225,000 working capital adjustment.57

The assets acquired and liabilities assumed are reflected in the Company’s consolidated balance sheet at December 31, 2016, and the results of operations of Lumewave are included in the consolidated statements of operations since August 16, 2014. The following table summarizes the purchase price allocation based on estimated fair values of assets acquired and liabilities assumed at the acquisition date (amounts in thousands):



	Amount
Cash and cash equivalents	$	630
Accounts receivable	107
Inventory	31
Other current assets	259
Property and equipment	23
Identifiable intangible assets	1,500
Goodwill	1,257
Accounts payable	(352		)
Accrued liabilities	(255		)
	$	3,200

Identifiable intangible assets include $800,000 in developed technology, $500,000 in customer relationships, and $200,000 for trade names. The identifiable intangible assets are being amortized over a period of 6.5 years. Transaction costs associated with the acquisition were not material. The method used to value the identified intangibles was an income method approach which incorporated a discount rate ranging from 21% to 22%.

Pro forma information for this acquisition is not presented as the results of the acquired business are not material to the Company’s consolidated financial statements.

The contingent consideration was measured at fair value based on management’s estimate of achieving the specified targets and discounted to its then present value of $925,000. The contingent consideration was payable in a combination of cash and the Company’s common stock. Both the fair value of the cash and equity portions of the contingent consideration were recorded as a liability and were remeasured each reporting period, with any change in their fair values recorded to earnings. The equity component of the contingent consideration was ultimately intended to be settled by issuing additional equity upon final determination of the targets being achieved.The number of shares to be issued was to be based on the average closing price of the Company's stock during the six days prior to the acquisition date.

As of December 31, 2015, the fair value of the contingent consideration was $318,000, and was recorded in accrued liabilities in the Company's consolidated balance sheets. During the quarter ended December 31, 2015, the Company determined that it was no longer probable that the targets specified in the purchase agreement would be met at a level requiring a full payout of the contingent consideration. Accordingly, the Company reduced the associated liability to management's best estimate of the fair value as of December 31, 2015. This resulted in a $577,000 adjustment, which was recorded as a reduction to general and administrative expenses in the Company's consolidated statements of operations. The remaining change in contingent consideration was due to amortization of interest on the contingent consideration.

The Company has classified the results of operations of the Grid business as discontinued operations for the year ended December 31, 2014. There was no activity related to the Grid business during the years ended December 31, 2016, and 2015. The table below provides a summary of the components of the net loss from discontinued operations for 2014 and excludes certain shared overhead costs that were previously allocated to the Grid segment as ASC 205-20 prohibits the allocation of general overhead costs to discontinued operations.

The sale agreement contains certain indemnification provisions related to the Grid business whereby the Company may have obligations related to the period it owned the Grid business. The Company believes the estimated fair value of these indemnification provisions are minimal and accordingly, no liability is recorded for these indemnifications as of December 31, 2016.

7. Stockholders’ Equity and Employee Stock Option Plans

(a) Reverse Stock Split

On December 7, 2015, the Company implemented a 1-for-10 reverse stock split. All share information contained within this report, including the accompanying consolidated financial statements and footnotes, have been retroactively adjusted to reflect the effects of the reverse stock split.

(b) Preferred Stock

As of December 31, 2016, the Company was authorized to issue 5,000,000 shares of $0.01 par value preferred stock, of which none was outstanding.

As of December 31, 2016, the Company was authorized to issue 10,000,000 shares of $0.01 par value common stock, of which 4,431,736 were outstanding.

(d) Tax Benefit Preservation Plan

On April 22, 2016, the Company announced that its Board of Directors (the “Board”) had adopted a Tax Benefit Preservation Plan (the “Tax Plan”) pursuant to which the Board authorized and declared a dividend distribution of one right (a “Right”) for each outstanding share of common stock of the Company to stockholders of record as of the close of business on May 6, 2016. Each Right entitles the registered holder to purchase from the Company one one-thousandth of a share of Series A Participating Preferred Stock, par value $0.01 per share, exercisable, except in certain circumstances, in the event that a person or group of affiliated or associated persons obtain beneficial ownership of 4.99% or more of the outstanding shares of the Company's common stock. The complete terms of the Rights are set forth in the Tax Plan, dated as of April 22, 2016, between the Company and Computershare Inc., as rights agent, and filed with the Securities and Exchange Commission on April 26, 2016. By adopting the Plan, the Board is helping to preserve the value of certain deferred tax benefits, including those generated by net operating losses (collectively, the “Tax Benefits”), which could be lost in the event of an “ownership change” as defined under Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”). The Plan reduces the likelihood that changes in the Company’s investor base will have the unintended effect of limiting the Company’s use of its Tax Benefits. The Board has established procedures to consider requests to exempt certain acquisitions of the Company’s securities from the Plan if the Board determines that it is in the best interests of the Company. Until they become exercisable, the Rights are inseparable from and trade with the Company's shares of common stock. The Rights have a de minimus fair value. The Tax Plan expires April 25, 2017.

(e) Stock Option Programs

The Company grants equity compensation awards under the 2016 Equity Incentive Plan (the "2016 Plan") and the 2016 Inducement Equity Incentive Plan (the "2016 Inducement Plan"). Prior to adoption of these Plans in 2016, the Company granted equity compensation awards under the 1997 Stock Plan (the “1997 Plan”), which terminated as of October 4, 2016. A more detailed description of each of the Plans can be found below.

Stock option and other equity compensation grants are designed to reward employees, officers, directors, and certain non-employee consultants for their long-term contribution to the Company, to align their interest with those of the Company's stockholders in creating stockholder value, and to provide incentives for them to remain with the Company. The number and frequency of equity compensation grants is based on competitive practices, operating results of the Company, and accounting regulations.

Historically, the Company has issued new shares upon the exercise of stock options. However, treasury shares are also available for issuance, although the Company does not currently intend to use treasury shares for this purpose.

2016 Equity Incentive Plan

In October 2016, the Company adopted the 2016 Equity Incentive Plan (the "2016 Plan") for employees, officers, directors, and non-employee consultants. In setting the initial share reserve under the 2016 Plan of 500,000 shares, the Company considered the number of outstanding awards and forecasted grants under the Plan. In addition to the initial share reserve of 500,000 shares, the 2016 Plan also includes any shares subject to awards under the 1997 Plan that, after the termination of the 1997 Plan, expire or otherwise terminate without having vested or without having been exercised in full and any shares issued pursuant to awards granted under the 1997 Plan that are forfeited to or repurchased by the Company.

As of December 31, ~~2016~~2017, there were a total of 1.21 million shares of Common Stock reserved for issuance under the 2016 Plan, of which ~~687~~892,~~036~~629 were subject to outstanding awards and ~~502~~187,~~825~~982 shares remained available for new awards under the Plan. Stock options granted under the 2016 Plan generally have a term of 10 years, and the exercise price of said stock options is determined by the Board of Directors (or a Committee of the Board of Directors), and, except for limited circumstances, will be at least equal to 100% of the fair market value per share of common stock on the date of grant (or at least 110% of such fair market value for an incentive stock option granted to a stockholder with greater than 10% voting power of all stock). RSUs, ~~Options~~Performance Units, and ~~awards~~Performance Shares issued by the Company under the 2016 Plan generally vest ratably over 2 to 3 years. In addition, certain of these awards have additional financial-based performance requirements that must be met before vesting can occur. Awards with performance-based vesting conditions expire no later than the 5 year anniversary of the grant date if the performance criteria have not been met.

The 2016 Plan also allows for the issuance of stock purchase rights and options that are immediately exercisable through execution of a restricted stock purchase agreement. Shares purchased pursuant to a stock purchase agreement may (but are not required to) be subject to vesting conditions, and the shares acquired may not be transferred by the participant until the vesting conditions (if any) are satisfied. In the event of termination of employment, the Company, at its discretion, may repurchase unvested shares at a price equal to the original issuance price. In addition, the 2016 Plan allows for the issuance of stock appreciation rights (“SARs”), restricted stock units (“RSUs”), and Performance Units and Performance Shares. SARs are rights to receive, in cash or shares of the Company's common stock, as designated on the grant date, the appreciation in fair market value of common stock between the exercise date and the date of grant. SARs may be granted alone or in tandem with options. The exercise price of a SAR will be at least equal to 100% of the fair market value per share of common stock on the date of grant. RSUs, Performance Units, and Performance Shares are awards that result in a payment to a participant, generally in the form of an issuance of shares of the Company's common stock, at such time as specified performance goals or other vesting criteria are achieved or the awards otherwise vest. RSUs, Performance Units, and Performance Shares issued by the Company generally vest in equal, annual installments over 4 years. In addition, certain of these awards have additional financial-based performance requirements that must be met before vesting can occur. Awards with performance-based vesting conditions expire no later than the 5 year anniversary of the grant date if the performance criteria have not been met.59

2016 Inducement Equity Incentive Plan

On April 20, 2016, the Company filed a Registration Statement on Form S-8 with the Securities and Exchange Commission to register 250,000 shares of common stock to be issued pursuant to the 2016 Inducement Plan. The purpose of the Inducement Plan is to facilitate the Company's ability to attract and retain the best available new hires by providing an inducement to such individual entering into employment with the Company or subsidiary of the Company. The Inducement Plan permits the grant of nonstatutory stock options, restricted stock, restricted stock units, stock appreciation rights, performance units, and performance shares, each with terms similar to those governed by the previously discussed 2016 Plan. Each award under the Inducement Plan is intended to qualify as an employment inducement award under NASDAQ Listing Rule 5635(c)(4).

71As of December 31, 2017, there were a total of 235,000 shares of Common Stock reserved for issuance under the 2016 Inducement Plan, of which 89,000 were subject to outstanding awards and 146,000 shares remained available for new awards under the Plan.

As of December 31, 2016, there were a total of 250,000 shares of Common Stock reserved for issuance under the 2016 Inducement Plan, of which 150,000 were subject to outstanding awards and 100,000 shares remained available for new awards under the Plan.

1997 Stock Plan (terminated October 4, 2016)

During 1997, the Company adopted the 1997 Stock Plan for employees, officers, directors, and non-employee consultants, which was amended and restated in May 2004, and further amended and restated in April 2013. During 2013, the Board determined that it was in the best interest of the Company and the stockholders to amend and restate the Plan. In setting the share reserve under the amended Plan, the Company considered the number of outstanding awards and forecasted grants under the Plan. As of March 31, 2013 a total of 2,097,283 shares of its Common Stock were reserved for issuance under the Plan, of which 550,540 shares were subject to outstanding awards and 1,546,743 shares remained available for new awards under the Plan. Upon approval of the amended Plan by the shareholders, the total number of shares issuable under the Plan after March 31, 2013, was reduced from 2,097,283 to 1,090,540, including the 550,540 shares subject to current outstanding awards plus an additional 540,000 shares for future new awards. In determining the size of the share reserve, the Company took into account historical grant practices and the rate of granting equity awards (“burn rate”). As discussed above, the 1997 Plan was terminated on October 4, 2016. As of the termination date, all outstanding awards granted under the 1997 Plan were transferred to the 2016 Plan. However, they will continue to be governed by the terms of the 1997 Plan.

Under the 1997 Plan, incentive stock options to purchase shares of common stock were eligible to be granted at not less than 100% of the fair market value. Options granted from May 6, 2003 to March 31, 2013, generally have a term of 5 years from the date of grant. All other options granted generally have a term of 10 years. The exercise price of stock options granted under the 1997 Plan is determined by the Board of Directors (or a Committee of the Board of Directors), but were at least equal to 100% of the fair market value per share of common stock on the date of grant (or at least 110% of such fair market value for an incentive stock option granted to a stockholder with greater than 10% voting power of all stock), except that up to 10% of the aggregate number of shares reserved for issuance under the 1997 Plan (including shares that have been issued or are issuable in connection with options exercised or granted under the 1997 Plan) were available have exercise prices that are from 0% to 100% of the fair market value of the common stock on the date of grant. Options generally vested ratably over four years.

The 1997 Plan also allowed for the issuance of stock purchase rights and options that were immediately exercisable through execution of a restricted stock purchase agreement. Shares purchased pursuant to a stock purchase agreement generally vested ratably over 4 years. In the event of termination of employment, the Company, at its discretion, may repurchase unvested shares at a price equal to the original issuance price. In addition, the 1997 Plan allowed for the issuance of stock appreciation rights (“SARs”), restricted stock awards (“RSAs”), and restricted stock units (“RSUs”). SARs are rights to receive, in cash or shares of the Company's common stock, as designated on the grant date, the appreciation in fair market value of common stock between the exercise date and the date of grant. To date, the Company has only issued SARs that can be settled in shares of the Company's common stock. SARs may be granted alone or in tandem with options. The exercise price of a SAR will be at least equal to 100% of the fair market value per share of common stock on the date of grant. SARs issued by the Company generally vest in equal, annual installments over 4 years, and expire on the 5 year anniversary of the grant date. RSUs and RSAs are awards that result in a payment to a participant, generally in the form of an issuance of shares of the Company's common stock, at such time as specified performance goals or other vesting criteria are achieved or the awards otherwise vest. RSUs and RSAs issued by the Company generally vest in equal, annual installments over 4 years. In addition, certain of these RSU and RSA grants have additional financial-based performance requirements that must be met before vesting can occur. RSUs and RSAs with performance-based vesting conditions expire no later than the 5 year anniversary of the grant date if the performance criteria have not been met.

The fair value of each RSU and RSA granted to employees was estimated on the date of grant by multiplying the number of shares granted times the fair market value of the Company's stock on the grant date.

The total intrinsic value of RSUs and RSAs vested and released during the years ended December 31, 2016, 2015, and 2014 was approximately $118,000, $379,000, and $1.2 million, respectively. The intrinsic value of vested and released RSUs and RSAs is calculated by multiplying the fair market value of the Company's stock on the vesting date by the number of shares vested. As of December 31, 2016, the number of RSUs and RSAs outstanding and expected to vest was 331,163, with a total intrinsic value of $1.6 million. The intrinsic value of the outstanding and expected to vest RSUs and RSAs is calculated based on the market value of the Company's closing stock price of $4.70 as of December 30, 2016, the last market trading day of 2016. 61

747. Stock-based Compensation

(a) Valuation of Options, SARs, and RSUs Granted

The Company has elected to use the Black-Scholes-Merton ("BSM") option-pricing model to estimate the fair value of stock options and SARs that it grants. The BSM model incorporates various assumptions including volatility, expected term of the option from the date of grant to the time of exercise, risk-free interest rates, and dividend yields. The weighted average fair value of options ~~and SARs~~ granted during the years ended December 31, ~~2016,~~2017 ~~2015,~~ and ~~2014,~~2016 was $23.~~55,~~09 ~~$4.54,~~ and $142.7055, respectively, and was determined using the following weighted average assumptions:

	Year ended December 31,
	2016	2015	2014
	2017	2016
Expected dividend yield	—%	—%	—%
Risk-free interest rate	1.27%	1.72%	~~2.0%~~
Expected volatility	5855.19%	5658.31%	~~66.3%~~
Expected term (in years)	53.1275	5.0812	~~5.98~~

The expected dividend yield reflects the fact that the Company has not paid any dividends in the past and does not currently intend to pay dividends in the foreseeable future. The risk-free interest rate assumption is based on U.S. Treasury yields in effect at the time of grant for the expected term of the option. The expected volatility is based on both the historical volatility of the Company's common stock over the most recent period commensurate with the expected life of the option as well as on implied volatility calculated from the market traded options on the Company's stock. The expected term has been calculated by applying the simplified method calculation to the 10-year term option grants made during ~~2014,~~2016 ~~2015,~~ and ~~2016~~2017, as the Company does not have relevant and adequate exercise history for such options. Prior to this, the expected term had been calculated by applying a Monte Carlo simulation model that incorporated the Company's historical data on post-vest exercise activity and employee termination behavior.

The grant date fair value of RSUs and RSAs granted to employees is determined by multiplying the fair market value of the Company's stock on the grant date times the number of RSUs and RSAs awarded. During the years ended December 31, 2016, 2015 and 2014, the Company issued a limited number of RSUs to non-employee consultants. The final measurement date for these awards is determined at the earlier of the date at which a commitment for performance by the consultant to earn the RSUs is reached, or the date at which the consultant's performance necessary for the RSUs to vest has been completed. Between the date of issuance and the final measurement date, which is expected to be the date the consultants' performance is complete and the awards vest, the awards are remeasured based on the fair market value of the Company's stock at each reporting date. During the year ended December 31, 2016, awards granted to non-employee consultants and the related share-based payment expense was not significant.62

The grant date fair value of RSUs and RSAs granted to employees is determined by multiplying the fair market value of the Company's stock on the grant date times the number of RSUs and RSAs awarded.

Between the date of issuance and the final measurement date, which is expected to be the date the consultants' performance is complete and the awards vest, the awards are remeasured based on the fair market value of the Company's stock at each reporting date. During the year ended December 31, 2017, awards granted to non-employee consultants and the related share-based payment expense were not significant.

As of December 31, 2014, there were 70,080 non-vested RSUs and RSAs that were granted in 2010, 2011, and 2014 which were subject to service-based vesting conditions as well as certain financial or other performance-based vesting requirements that must be achieved before vesting can occur. The following table contains pertinent information regarding these outstanding awards as of December 31, 2014 (in thousands except for number of awards granted):

Through December 31, 2017, cumulative compensation expense of $132,000 associated with the 143,283 unvested RSUs granted in January 2017 had been recognized. From the date of grant through December 31, 2017, the Company believed it was probable that the performance requirements associated with certain of these awards would be achieved and therefore recognized expense on those specific awards. However, as of March 31, June 30, and September 30, 2017, the Company determined that separate performance conditions related to the remainder of the awards granted in January 2017 was improbable of achievement. Accordingly, no compensation expense has been recognized on these additional awards. As the performance conditions required for the vesting of these additional awards were not met as of December 31, 2017, the final date that the performance conditions could be met, the Company expects approximately 114,379 awards will expire unvested in March 2018 and will be returned to the Plan.

Through June 30, 2012, cumulative compensation expense of $264,000 associated with the 13,000 unvested RSUs and RSAs granted in 2010 and 2011 had been recognized. From the date of grant through June 30, 2012, the Company had believed it was probable that the associated performance requirements would be achieved and therefore recognized expense on these awards. During the third quarter of 2012, the Company believed that the performance condition was no longer probable of achievement, however the Company had also not yet determined that the performance condition was improbable of achievement. Accordingly, expense recognition was discontinued beginning in the third quarter of 2012. As of December 31, 2013, the Company determined that the performance condition was improbable of achievement and therefore the cumulative compensation expense of $264,000 associated with these awards was reversed in the quarter ended December 31, 2013. No further compensation expense associated with these awards has been recorded. These awards expired unvested in April 2015.

In addition to the awards issued in 2010 and 2011, there were 95,330 non-vested RSAs as of December 31, 2014 with a grant date fair value of $2.3 million that were granted on June 10, 2014, which were also subject to service-based vesting conditions as well as certain performance-based vesting requirements that must be achieved before vesting can occur. These awards vested over a nine month period ending March 14, 2015, provided the performance conditions were met as of December 31, 2014. Of these RSAs issued in June 2014, 30,200 awards with a total fair value of approximately $743,000 were granted to employees of the Grid business. As of September 30, 2014, in conjunction with the sale of the Grid business, the Company reversed all compensation expense previously recognized associated with these awards as they will not vest. Additionally, as of December 31, 2014, 8,050 awards with a grant date fair value of approximately $198,000 were granted to employees who terminated their employment during 2014. Accordingly, the Company reversed all compensation expense previously recognized associated with these awards as they will not vest. As of December 31, 2014, the Company determined that the performance conditions associated with a portion of the remaining unvested awards with a grant date fair value of $965,000 would not be achieved and therefore any previously recorded expense associated with these awards was reversed and no additional expense was recorded during the year ended December 31, 2014.

c) Expense Allocation

~~Compensation expense for all share-based payment awards has been recognized using the multiple-option approach.~~ As ~~discussed in Note 1, during the fourth quarter~~ of ~~2016, the Company elected to early adopt ASU~~December ~~2016-09~~31, ~~Compensation~~ ~~– Stock Compensation (Topic 718)~~2017, ~~with~~total retrospective application to January 1, 2016, the beginning of the annual period that includes the interim period of adoption.

The goodwill acquired as part of the ARIGO transaction is valued in Euros, and is therefore subject to foreign currency translation gains and losses.

In performing Step 1 of the impairment test, the Company estimated the fair value of the reporting unit using the income approach. The income approach is based on a discounted cash flow analysis and calculates the fair value of the reporting unit by estimating the after-tax cash flows attributable to the reporting unit and then discounting the after-tax cash flows to a present value, using a weighted average cost of capital (“WACC”). The cash flows used in the income approach were based on two scenarios, cash flows associated with a winding down of the business and cash flows associated with a sale of the business. Management's assumptions included forecasted revenues and operating income for the wind down scenario and estimated proceeds from the sale of the business based on known third-party interest. We calculated the fair value for the Grid business by using a probability weighted average of the estimated fair value from both scenarios, with significantly higher weight placed on the wind down scenario. Ultimately, in the third quarter of 2014, the Company was able to locate a buyer for the Grid business during the third quarter of 2014, which led to the disposition of the business on September 30, 2014.

Based on the above analysis, it was determined that the carrying value of the Grid business, including goodwill, exceeded the fair value of the reporting unit, requiring the Company to perform Step 2 of the goodwill impairment test to measure the amount of impairment loss, if any10. Commitments In performing Step 2 of the goodwill impairment test, the Company compared the implied fair value of the reporting unit’s goodwill to its carrying value of goodwill. This test resulted in a non-cash, goodwill impairment charge of $3.4 million and a write-off of all goodwill associated with the Grid division, which was recognized during the three months ended June 30, 2014. This impairment has been reported as part of the discontinued operations results for the year ended December 31, 2014. As a result, the Company had no goodwill remaining related to the Grid business, with the entire remaining goodwill balance of $5.9 million at December 31, 2014, being attributable to the IIoT reporting unit. Contingencies

2015 Goodwill Impairment - During the quarter ended December 31, 2015, the Company concluded there were indicators of a potential goodwill impairment, resulting primarily from a continued decline in the Company's stock price and other market indicators, as well as a change in the Company's forecast for certain revenue streams. As a result of these indicators of impairment, the Company performed an impairment test of goodwill as of December 31, 2015.

As a result of the sale of the Grid business, the Company operates as one reporting unit. In performing Step 1 of the impairment test, the Company estimated the fair value of the reporting unit using a combination of approaches, including, among others, the income approach and the market approach. We calculated the fair value for the Company by using a weighted average of the various approaches, with significantly higher weight placed on the market approach.

Based on this analysis, it was determined that the carrying value of the business, including goodwill, exceeded the fair value of the reporting unit, requiring the Company to perform Step 2 of the goodwill impairment test to measure the amount of impairment loss, if any. In performing Step 2 of the goodwill impairment test, the Company compared the implied fair value of the reporting unit’s goodwill to its carrying value of goodwill. This test resulted in a non-cash, goodwill impairment charge of $5.7 million, which was recognized during the three months ended December 31, 2015. As a result, the Company no longer has has any goodwill remaining on its balance sheet as of December 31, 2015.

Identifiable Intangible Assets

The Company's identifiable intangible assets as of December 31, 2016, relate to the acquisition of Lumewave, Inc. in August 2014 (see Note 4 for additional details). The identifiable intangible assets include $800,000 in developed technology, $500,000 in customer relationships, and $200,000 for trade names.

11. Commitments and Contingencies

(a) Lease Commitments

The Company leases facilities under operating leases for its personnel located within the United States and in several foreign countries throughout Europe and Asia. These operating leases expire on various dates through 2019, and in some instances are cancelable with advance notice. Lastly, the Company also leases certain equipment and, for some of its sales personnel, automobiles. These operating leases are generally less than five years in duration.

As of December 31, ~~2016~~2017, future minimum lease payments under all operating leases were as follows (in thousands):

2017	$	974
2018		$	950
2018		841
2019		483
2019		467
2020		$	16
Total payments	$	2,282
2021		$	12
Total payments		$	1,461

Rent expense for all operating leases was approximately $964,000 for 2017 and $994,000 for 2016. Although certain of the operating lease agreements provide for escalating rent payments over the term of the lease, rent expense under these agreements is recognized on a straight-line basis. As of December 31, ~~2016~~2017, the Company has accrued approximately $135,000 of deferred rent related to these agreements, of which approximately $72,000 is reflected in accrued liabilities while the remainder is reflected in other long-term liabilities in the accompanying consolidated balance sheets. As of December 31, 2016, the Company had accrued approximately $193,000 of deferred rent related to its lease agreements, of which approximately $59,000 is reflected in current liabilities while the remainder is reflected in other long-term liabilities in the accompanying consolidated balance sheets.

As of December 31, 2015, the Company had accrued approximately $112,000 of deferred rent related to its lease agreements, of which approximately $15,000 is reflected in current liabilities while the remainder is reflected in other long-term liabilities in the accompanying consolidated balance sheets.

As discussed in Note 5 - Discontinued Operations, in conjunction with the sale of its Grid division, the Company entered into a sublease with S&T for a portion of its corporate headquarters facility. As of December 31, 2015, the sublease was cancelled in conjunction with the Company's termination of its main headquarters leases as discussed in Note 3.

Rent expense, net	$	994	$	575		$	1,121

(b) Royalties

The Company has certain royalty commitments associated with the shipment and licensing of certain of its products. Royalty expense is generally based on a dollar amount per unit shipped or a percentage of the underlying revenue. Royalty expense, which is recorded as a component of cost of revenues in the Company's consolidated statements of operations, was approximately $~~264~~260,000, ~~$390,000,~~ and $~~500~~264,000 for the years ended December 31, ~~2016,~~2017 ~~2015,~~ and ~~2014~~2016, respectively. ~~During the year ended December 31, 2014, royalty expense reported in discontinued operations was approximately $1,000.~~

The Company will continue to be obligated for royalty payments in the future associated with the shipment and licensing of certain of its products. The Company is currently unable to estimate the maximum amount of these future royalties. However, such amounts will continue to be dependent on the number of units shipped or the amount of revenue generated from these products.

In the normal course of business, the Company provides indemnifications of varying scope to its customers against claims of intellectual property infringement made by third parties arising from the use of its products. Historically, costs related to these indemnification provisions have not been significant. However, the Company is unable to estimate the maximum potential impact of these indemnification provisions on its future results of operations.

As permitted under Delaware law, the Company has entered into agreements whereby it indemnifies its officers and directors for certain events or occurrences while the officer or director is, or was serving, at the Company's request in such capacity. The indemnification period covers all pertinent events and occurrences during the officer's or director's lifetime. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited. However, the Company has directors and officers insurance coverage that would enable it to recover a portion of any future amounts paid. The Company believes the estimated fair value of these indemnification agreements in excess of the applicable insurance coverage is minimal, if any.

(d) Taxes

The Company conducts operations in many tax jurisdictions throughout the world. In many of these jurisdictions, non-income based taxes such as property taxes, sales and use taxes, and value-added taxes are assessed on the Company's operations in that particular location. While the Company strives to ensure compliance with these various non-income based tax filing requirements, there have been instances where potential non-compliance exposures have been identified. In accordance with accounting principles generally accepted in the United States of America, the Company makes a provision for these exposures when it is both probable that a liability has been incurred and the amount of the exposure can be reasonably estimated. To date, such provisions have been immaterial, and the Company believes that, as of December 31, ~~2016~~2017, it has adequately provided for such contingencies. However, it is possible that the Company's results of operations, cash flows, and financial position could be harmed if one or more non-compliance tax exposures are asserted by any of the jurisdictions where the Company conducts its operations.

be harmed if one or more non-compliance tax exposures are asserted by any of the jurisdictions where the Company conducts its operations.

(e) Legal Actions

From time to time, in the ordinary course of business, the Company may be subject to other legal proceedings, claims, investigations, and other proceedings, including claims of alleged infringement of third-party patents and other intellectual property rights, and commercial, employment, and other matters. In accordance with generally accepted accounting principles, the Company makes a provision for a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel, and other information and events pertaining to a particular case. While the Company believes it has adequately provided for such contingencies as of December 31, ~~2016~~2017, the amounts of which were immaterial, it is possible that the Company’s results of operations, cash flows, and financial position could be harmed by the resolution of any such outstanding claims.

Line of Credit

~~Until December 2014, the Company maintained a $5.0 million line of credit with its primary bank.~~ The ~~line of credit was secured by a collateral of the first priority on $6.3 million of the~~ Company's ~~investments~~maintains ~~placed in a separate account. In December 2014, the Company cancelled this line of credit. It continues to maintain~~ an operating credit line of $1.0 million with its primary bank for company credit card purchases. This line of credit is secured by a collateral of the first priority on $1.3 million of the Company's investments (presented as restricted investments in the consolidated balance sheets). The restricted investments are classified as current assets due to the contractual duration of the underlying credit agreement.

As of December 31, 2017 and 2016, a valuation allowance has been recorded against 100% of the net deferred tax asset. A valuation allowance is recognized if, based on the weight of the available evidence, it is more likely than not that some portion or all of the deferred tax asset will not be realizable in a particular tax jurisdiction. All available evidence, both positive and negative, is considered to determine whether, based on the weight of that evidence, a valuation allowance is needed for some portion or all of a deferred tax asset. The Company determined that it is more likely than not that it will not realize a benefit from its United States deferred tax assets based on historical cumulative losses incurred in the United States. Therefore, a valuation allowance has been maintained on all deferred tax assets. The components of the net deferred income tax asset are as follows (in thousands):

As of December 31, 2017, part of the Company's valuation allowance on deferred tax assets pertains to certain tax credits and net operating loss carry forwards. In the future, it will reduce the valuation allowance associated with these credits and losses upon the earlier of the period in which it utilizes them to reduce the amount of income tax it would otherwise be required to pay on its income tax returns, or when it becomes more likely than not that the deferred tax assets are realizable. In addition, the Internal Revenue Code of 1986, as amended, contains provisions that limit the net operating loss and credit carry forwards available for use in any given period upon the occurrence of certain events, including a significant change in ownership interests. The Company performed an analysis of the ownership changes in 2016. Through the date of the analysis, the Company did not experience any ownership change that would limit its net operating loss and credit carry forwards. The Company's net operating loss and credit carry forwards may be limited if an ownership change has occurred since the analysis was performed or if one were to occur in future periods.

17. Segment Disclosure

ASC Topic 280, Segment Reporting, establishes standards for reporting information about operating segments, products and services, geographic areas of operations and major customers. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing business performance. The Company’s chief operating decision-making group is the Executive Staff, which is comprised of the Chief Executive Officer and his direct reports (CODM).

In September 2014, the Company sold its Grid business to S&T, thus reducing the number of reportable segments from two to one. For the year ending December 31, 2014, the Grid business is captured in discontinued operations.

The Company operates in one principal industry segment - the IIoT segment, which is its reportable segment. The IIoT segment sells products and services aimed at Embedded Control Platforms, such as LONWORKS and IzoT, which include components, control nodes, and development software, and which are sold typically to Original Equipment Manufacturers (OEMs) to build into their industrial application solutions. These platforms allow a single device to be brought to market as a LONWORKS®, BACnet®, or other protocol-supporting device; and it can be used with any underlying wired or wireless communications link, such as Ethernet, RS-485, Wi-Fi, 15.4, or Echelon’s free topology (FT) standard. The IzoT platform provides a smooth migration path for legacy devices to the IIoT. The product portfolio includes Smart Transceivers, SmartServer Controllers, LNS and OpenLNS Operating Systems, Outdoor Lighting Controllers, SmartServer Segment Controllers and PL/RF Bridges.

The Company operates in three main geographic areas: the Americas; Europe, Middle East and Africa (“EMEA”); and Asia Pacific / Japan (“APJ”). Each geographic area provides products and services to the Company’s customers located in the respective region. The Company’s long-lived assets include property and equipment, goodwill, purchased technology, and deposits on its leased facilities. Long-lived assets are attributed to geographic areas based on the country where the assets are located. As of December 31, ~~2016~~2017 and December 31, ~~2015~~2016, long-lived assets of approximately $2.21 million and $2.62 million, respectively, were domiciled in the United States. Long-lived assets for all other locations are not material to the consolidated financial statements.

In North America, the Company sells its products primarily through a direct sales organization and select third-party electronics representatives. Outside North America, the Company sells its products through direct sales organizations in EMEA and APJ, value-added resellers, and local distributors. Revenues are attributed to geographic areas based on the country where the products are shipped to or the services are delivered. Summary revenue information by geography for the years ended December 31, ~~2016,~~2017 ~~2015~~ and ~~2014~~2016 is as follows (in thousands):

(“Echelon-Holley”). The joint venture's intended focus was on the development and sales of smart energy products for China and rest-of-world markets. The Company has a 51% ownership interest in the joint venture and exercises controlling influence. Therefore, Echelon-Holley’s accounts are included in the Company’s consolidated financial statements as of December 31, ~~2016~~2017, and for the ~~three~~two years then ended. Holley Metering’s interests in Echelon-Holley’s net assets are reported in the noncontrolling interest in subsidiary on the consolidated balance sheet as of December 31, ~~2016~~2017 and ~~2015~~2016. Net loss attributable to the noncontrolling interest in Echelon-Holley was $0, ~~$0, and $535,000~~ during the years ended December 31, ~~2016,~~2017 ~~2015,~~ and ~~2014, respectively~~2016.

In addition, the net loss attributable to the non-controlling interests ~~have~~were ~~also been~~ presented as part of discontinued operations in the consolidated statement of operations for the year ended December 31, 2014.

During the quarter ended September 30, 2015, the Company concluded that it would no longer pursue a sale, but would instead work with Holley Metering to shut the joint venture down. The remaining net assets of the joint venture were immaterial as of September 30, 2015. As the net losses attributable to the joint venture were immaterial in all years, they have been presented as part of discontinued operations in the consolidated statements of operations for the year ended December 31, 2014.
