NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

1.    Summary of Significant Accounting Policies

Basis of Presentation

The condensed consolidated financial statements include the accounts of Echelon Corporation, a Delaware corporation, its wholly-owned subsidiaries, and a subsidiary in which it has a controlling interest (collectively referred to as the “Company”). The Company reports non-controlling 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.

While the financial information furnished is unaudited, the condensed consolidated financial statements included in this report reflect all adjustments (consisting only of normal recurring adjustments) which the Company considers necessary for the fair presentation of the results of operations for the interim periods covered, and of the financial condition of the Company at the date of the interim balance sheet. The results for interim periods are not necessarily indicative of the results for the entire year. The condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements for the year ended December 31, 2016 included in its Annual Report on Form 10‑K.

There have been no material changes to the Company’s significant accounting policies as compared to the significant accounting policies described in its Annual Report on Form 10‑K for the fiscal year ended December 31, 2016.

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 29.1% of revenues for the six months ended June 30, 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.

• In an effort to manage costs and inventory risks, the Company has decreased the inventory levels of certain products. If there is an unexpected increase in demand for these items, the Company might not be able to supply its 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 Condensed Consolidated Financial Statements and accompanying notes. Significant estimates and judgments are used for revenue recognition, performance-based equity compensation, inventory valuation, intangible asset valuation, contingent consideration valuation, allowance for warranty costs, 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. There was no impact on the Company's financial statements as a result of the adoption.

(ii) New Accounting Standards Not Yet Effective

In 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.

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 currently anticipates adopting the standard using the full retrospective method to restate each prior reporting period presented.

The standard will be effective for Echelon in the fiscal year beginning January 1, 2018. The Company currently anticipates the standard will have a material impact on its financial statements and disclosures, and continues to make progress in assessing all potential impacts of the standard, including any impacts of recently issued amendments. 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 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 the distribution channel. During the year ended December 31, 2016, the Company recognized approximately $14.7 million of revenue sold through such distributors. As of December 31, 2016, the amount of revenue and cost of revenues sold through the distribution channel that were deferred was $2.6 million and $668,000, respectively.

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.

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, in limited circumstances, software post-contract support services) and training.

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 certain 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.

Deferred Revenue and Deferred Cost of Revenues

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

Restricted Investments

As of June 30, 2017, restricted investments consist of balances maintained by the Company with an investment advisor in money market funds and permitted treasury bills. These balances represent collateral for a $1.0 million operating line of credit issued to the Company by its primary bank for credit card purchases. Because the Company’s agreement with the lender prevents the Company from withdrawing these funds, they are considered restricted.

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:

• 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 and liabilities required to be measured at fair value on a recurring basis at June 30, 2017, are its fixed income available-for-sale securities. See Note 2 of these Notes to condensed consolidated financial statements for a summary of the input levels used in determining the fair value of these assets and liabilities as of June 30, 2017.

Long-Lived Assets

We perform periodic reviews to determine whether facts and circumstances exist that would indicate that the carrying

9

amounts of property, plant and equipment and long-lived intangible assets might not be fully recoverable. If facts and circumstances indicate that the carrying amount of these assets might not be fully recoverable, we compare projected undiscounted net cash flows associated with the related asset or group of assets over their estimated remaining useful lives against their respective carrying amounts. In the event that the projected undiscounted cash flows are not sufficient to recover the carrying value of the assets, the assets are written down to their estimated fair values based on the expected discounted future cash flows attributable to the assets. Evaluation of impairment of property, plant and equipment and long-lived intangible assets requires estimates in the forecast of future operating results that are used in the preparation of the expected future undiscounted cash flows. Actual future operating results and the remaining economic lives of our property, plant and equipment and long-lived intangible assets could differ from our estimates used in assessing the recoverability of these assets. These differences could result in impairment charges, which could have a material adverse impact on our results of operations. 

Contingent Consideration

During the quarter ended March 31, 2016, the contingent consideration payable to Lumewave's shareholders, which the Company recognized upon its purchase of Lumewave in August 2014, 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 condensed consolidated statements of operations.

2. Financial Instruments:

The Company’s financial instruments consist of cash equivalents, restricted investments, short-term investments, accounts receivable, and accounts payable. 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, restricted investments, or short-term investments, and accounts receivable. 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 accounts receivable, 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 to mitigate the risk of uncollectibility, such as a bank guarantee. 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.

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 available-for-sale investments, 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 June 30, 2017 (in thousands):

	Fair Value Measurements at Reporting Date Using
			Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Inputs		Significant Unobservable Inputs

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

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

Cash equivalents consist of either investments with remaining maturities of three months or less at the date of purchase, or money market funds for which the carrying amount is a reasonable estimate of fair value.

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 by comparing prices obtained from a third party independent source.

As of June 30, 2017, the Company’s available-for-sale securities had contractual maturities of six months and an average remaining term to maturity of three months. As of June 30, 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):

	Amortized Cost		Aggregate Fair Value		Unrealized Holding Gains		Unrealized Holding Losses
U.S. government securities	$	11,970	$	11,968	$	—	$	2

The amortized cost basis, aggregate fair value and gross unrealized holding gains and losses for the Company’s available-for-sale short-term investments, by major security type, were as follows as of December 31, 2016 (in thousands):

	Amortized Cost		Aggregate Fair Value		Unrealized Holding Gains		Unrealized Holding Losses
U.S. government securities	$	11,984	$	11,983	$	—	$	1

Market values were determined for each individual security in the investment portfolio. 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.

3. Earnings Per Share:

The computation of diluted net loss per share does not include stock options, performance shares, and contingently issuable shares of 923,306 and 355,338 for the three and six months ended June 30, 2017 and 2016, respectively, because the effect of their inclusion would be anti-dilutive based on their respective exercise prices.

4. Stockholders’ Equity and Employee Stock Option Plans:

On April 17, 2017, the Company's Board of Directors approved an amendment to the Tax Benefit Preservation Plan (the "Tax Plan"), dated as of April 22, 2016, by and between the Company and Computershare Inc., as rights agent (the “Rights Agent”), to extend the Final Expiration Date (as such term is defined in the Tax Plan) to April 25, 2019.

Stock-based Compensation Expense

The following table summarizes stock-based compensation expense for the three and six months ended June 30, 2017 and 2016 and its allocation within the condensed consolidated statements of operations (in thousands):

	Three Months Ended					Six Months Ended
	June 30,					June 30,
	2017		2016			2017		2016
Cost of revenues	$	45	$	(28	)	$	74	$	(17	)
Product development	119		41			243		40
Sales and marketing	27		43			129		(78		)
General and administrative	251		121			463		231
Total	$	442	$	177		$	909	$	176

The negative expense amounts reflected in the table above are primarily due to the reversal of previously recognized expense resulting from the forfeiture of equity awards for certain employees whose employment terminated during the respective periods.

Stock Award Activity

There were no options exercised during the three and six months endedJune 30, 2017 and 2016.

The total fair value of RSUs vested and released during the three and six months ended June 30, 2017 was $147,000 and $196,000, respectively. The total fair value of RSUs vested and released during the three and six months ended June 30, 2016 was approximately $92,000 and $96,000, respectively. The fair value is calculated by multiplying the fair market value of the Company’s common stock on the vesting date by the number of shares of common stock issued upon vesting.

5.    Significant Customers:

The Company markets its products and services throughout the world to original equipment manufacturers (OEMs) and systems integrators in the building, industrial, transportation, utility/home, and other automation markets. During the three and six months ended June 30, 2017 and 2016, the Company had two customers that accounted for a significant portion of its revenues: Avnet Europe Comm VA (“Avnet”), the Company’s primary distributors of its IIoT products in Europe and Japan, and Enel Distribuzione Spa ("Enel"), an Italian utility company. For the three and six months ended June 30, 2017 and 2016, the percentage of the Company’s revenues attributable to sales made to these customers was as follows:

	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2017		2016		2017		2016
Avnet	28.6	%	29.9	%	29.1	%	28.3	%
Enel	—	%	—	%	—	%	7.9	%
Total	28.6	%	29.9	%	29.1	%	36.2	%

6. Commitments and Contingencies:

Legal Actions

From time to time, in the ordinary course of business, the Company may be subject to certain legal proceedings, claims, investigations, and other proceedings, including claims of alleged infringement of third-party patents and other intellectual property rights, and commercial, employment, or 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 June 30, 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.

12

Line of Credit

As of June 30, 2017, the Company maintained 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 condensed consolidated balance sheets). The restricted investments are classified as current assets due to the contractual duration of the underlying credit agreement.

7. Accumulated Other Comprehensive Income (Loss), Net of Tax (Amounts in thousands):

Other accrued liabilities	456		484
	$	1,732	$	2,174

10.    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). The Company operates in one principal industry segment - the IIoT segment, which is its reportable segment.

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 and other assets include property and equipment, acquired intangible assets, and

13

deposits on its leased facilities. Long-lived assets are attributed to geographic areas based on the country where the assets are located. As of June 30, 2017 and December 31, 2016, long-lived assets of approximately $2.0 million and $2.2 million, respectively, were domiciled in the United States. Long-lived assets for all other locations are not material to the condensed 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, value-added resellers, and local distributors, primarily in EMEA and APJ. 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 three and six months endedJune 30, 2017 and 2016 is as follows (in thousands):

	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2017		2016		2017		2016
Americas	$	3,295	$	3,154	$	6,465	$	5,709
EMEA	2,774		3,189		5,649		7,861
APJ	1,952		1,718		3,706		3,138
Total	$	8,021	$	8,061	$	15,820	$	16,708

For information regarding the Company’s major customers, please refer to Note 5, Significant Customers.

11. Income Taxes:

The provision for income taxes for the three months ended June 30, 2017 and 2016 was $29,000 and $51,000, respectively. The provision for income taxes for the six months endedJune 30, 2017 and 2016 were $23,000 and $57,000, respectively. The difference between the statutory rate and the Company’s 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.

As of June 30, 2017 and December 31, 2016, the Company had gross unrecognized tax benefits of approximately $9.3 million and $9.2 million, respectively, of which $357,000 and $364,000, respectively, if recognized, would impact the effective tax rate on income from continuing operations. The Company’s policy is to recognize interest and/or penalties related to unrecognized tax benefits in income tax expense. As of June 30, 2017 and December 31, 2016, the Company had accrued $52,000 and $62,000, respectively, for interest and penalties. The $10,000 reduction in interest and penalties on gross unrecognized tax benefits during the six months ended June 30, 2017 was primarily attributable to the expiration of the statute of limitations in certain foreign jurisdictions.     

12. Related Parties:

In June 2000, the Company entered into a stock purchase agreement with Enel pursuant to which Enel purchased 300,000 newly issued shares of its 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 the Company’s knowledge, Enel has disposed of none of its 300,000 shares. Under the terms of the stock purchase agreement, Enel has the right to nominate one member of the Company’s board of directors. While a representative of Enel served on the board until March 14, 2012, no Enel representative is presently on the board.

In October 2006, the Company entered into a new development and supply agreement with Enel. Under the development and supply agreement, Enel and its contract manufacturers purchase additional electronic components and finished goods from the Company. The development and supply agreement expired in March 2016.

For the three and six months ended June 30, 2017, the Company recognized no revenue from products sold to Enel and its designated manufacturers. For the three and six months ended June 30, 2016, the Company recognized revenue from products sold to Enel and its designated manufacturers of approximately $0 and $1.3 million, respectively.

As of June 30, 2017 and December 31, 2016, none of the Company’s total accounts receivable balance related to amounts owed by Enel and its designated manufacturers.

13. Joint Venture:

On March 23, 2012, the Company entered into an agreement with Holley Metering Limited (“Holley Metering”), a designer and manufacturer of energy meters in China, to create a joint venture, Zhejiang Echelon-Holley Technology Co., Ltd. (“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 51.0% ownership interest in the joint venture and exercises controlling influence. Therefore, Echelon-Holley’s accounts are included in the Company’s condensed consolidated financial statements as of June 30, 2017 and 2016, and for the six months then ended. Holley Metering’s interests in Echelon-Holley’s net assets are reported in the non-controlling interest in subsidiary on the condensed consolidated balance sheet as of June 30, 2017. Net loss attributable to the non-controlling interest in Echelon-Holley was $0 and $0 during the three and six months endedJune 30, 2017 and 2016, respectively.

As of June 30, 2017, Echelon and Holley Metering had contributed in cash a total of approximately $4.0 million in Share Capital, as defined in the joint venture agreement, to Echelon-Holley in proportion to their respective ownership interests.

In connection with the decision to sell the Grid business announced in the third quarter of 2014, the Company undertook a process to sell the remaining net assets of the joint venture and recorded the net assets and liabilities of the joint venture at the lower of their carrying amount or fair value less cost to sell, and classified them as held for sale on the accompanying balance sheet at December 31, 2014. The major classes of assets and liabilities that were classified as held for sale were inventory, deferred revenues and the related deferred costs of sales, and accrued liabilities.

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 of June 30, 2017, the Company is continuing to work with Holley Metering to complete the shut-down.

14. Restructuring:

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

The following table sets forth a summary of restructuring activities related to the Company's 2016 restructuring program (in thousands):

	December 31, 2016		Costs Incurred		Cash Payments			June 30, 2017
Accrued termination benefits	$	273	$	—	$	(88	)	$	185

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 plan to focus our product development spend in our foundational technology to broaden the applicability of our control networking platform into new markets; our predictions about the smart energy market, increased pricing pressures and worldwide macro-economic conditions; our projections of IIoT revenues; our expectations on shipments to Enel and revenues from Enel; our expectation that we will achieve a return on our investment of resources into our products; estimates of our future gross margins and factors affecting our gross margins; 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 IIoT revenues will not fluctuate significantly from foreign currency sales; estimates of our interest income and expense; our belief that we have adequately provided for legal contingencies; and our belief that we have made adequate provisions for tax exposure and legal matters. 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 “Factors That May Affect Future Results of Operations” 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, except as required by law.

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.

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.

* As of June 30, 2017 and December 31, 2016, includes $1.3 million of restricted investments presented separately on condensed consolidated balance sheet

• Revenues: Our revenues decreased by 0.5% during the second quarter of 2017 as compared to the same period in 2016, and decreased by 5.3% during the six months ended June 30, 2017 as compared to the same period in 2016. The decrease in revenues between the two six-month periods was mainly due to a decrease in sales of components sold to Enel. For further analysis please see the topic Revenues in the Results of Operations discussion later in this section.

• Gross margin: Our gross margins decreased by 1.2 percentage points during the second quarter of 2017 as compared to the same period in 2016, and increased by 0.1 percentage points during the six months ended June 30, 2017 as compared to the same period in 2016. These reduction in gross margins during the six months ended June 30, 2017 was primarily due to a an increase in indirect costs. For further analysis please see the topic Gross Profit and Gross Margin in the Results of Operations discussion later in this section.

• Operating expenses: Our operating expenses decreased by 3.7% and 0.9% during the three and six months ended June 30, 2017, respectively, as compared to the same periods in 2016. The decrease between the two quarterly periods was due to reductions in general and administrative and sales and marketing expenses, partially offset by an increase in our product development expenses. For the six months ended June 30, 2017, the decrease was primarily driven by reductions in our general and administrative spending which were partially offset by an increase in product development expenses. In addition, during the first quarter of 2016, we recorded a $318,000 reduction in the accrual for contingent consideration we expected to owe the former Lumewave shareholders, which reduced our general and administrative expenses. Excluding that expense reduction, our operating expenses declined by approximately $425,000, or 4%, during the first six months of 2017 as compared to the same period in 2016. For further analysis please see the topic Operating Expenses in the Results of Operations discussion later in this section.

• Net loss: We generated a net loss of $1.4 million during the second quarter of 2017 compared to $763,000 during the same period in 2016. This increase in our net loss was mainly attributable to an increase in foreign currency translation losses. For the six months ended June 30, 2017, we generated a net loss of $2.6 million compared to $1.6 million for the same period in 2016. The primary drivers behind the $931,000increase in our net loss between the two six month periods were lower revenues and corresponding gross profit, the $318,000 reduction in the accrual for contingent consideration we expected to owe the former Lumewave shareholders discussed above, and increased foreign currency translation losses, all of which was partially offset by a reduction in our operating expenses.

17

• Cash, cash equivalents, and short-term investments: During the first six months of 2017, our cash, cash equivalents, and short-term investment balance decreased by 9.1%, from $23.0 million at December 31, 2016 to $21.0 million at June 30, 2017. This decrease was primarily the result of cash used in operations of $2.1 million (driven primarily by our net loss of $2.6 million).

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our discussion and analysis of our financial condition and results of operations is based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. For further information on our significant accounting policies, see the Notes to our condensed consolidated financial statements included in Part 1 of this Report. Our critical accounting policies and estimates are also described in Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations" and Note 1, “Significant Accounting Policies” of Notes to consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2016, which we filed with the Securities and Exchange Commission in March 2017. 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 revenues, 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.

During the six months ended June 30, 2017, there were no material changes to our critical accounting policies or in the matters for which we make critical accounting estimates in the preparation of our condensed consolidated financial statements as compared to those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2016.

RESULTS OF OPERATIONS

The following table reflects the percentage of total revenues represented by each item in our condensed consolidated statements of operations for the three and six months ended June 30, 2017 and 2016:

	Three Months Ended June 30,				Six Months Ended June 30,

Total revenues	$	15,820	$	16,708	$	(888	)	(5.3	)%

Our revenues are primarily comprised of sales of our hardware products, and to a lesser extent, revenues we generate from sales of our software products and from our customer support and training offerings. Included in these totals are components we sell to Enel.

Excluding sales to Enel, a related party, which are discussed more fully below, our revenues remained relatively unchanged during the three months ended June 30, 2017, as compared to the same period in 2016, and increased by approximately $425,000, or 3%, during the six months ended June 30, 2017, as compared to the same period in 2016. The increase between the two six month periods was primarily due to increases in sales made to customers in the Americas and APJ regions, partially offset by a reduction in sales made to customers in the EMEA region. We have seen a loss in market share over the last several years due primarily to reduced investment in research and development and marketing, especially in our LONWORKS portfolio of products, which has caused a decrease in our embedded system revenues. In addition, the continued poor economic conditions in the EMEA region have also contributed to the year-over-year decline. Lastly, sales of components we make to our former Grid division also declined during the three and six months ended June 30, 2017 as compared to the same periods in 2016.

The portion of our revenues conducted in currencies other than the United States dollar, principally the Japanese Yen, was about 4.0% for the six months ended June 30, 2017 and 3.4% for the same period in 2016. Our revenues will continue to be subject to fluctuations in the exchange rates between the United States dollar and the foreign currencies in which we sell these products and services. In general, if the dollar were to weaken against these currencies, our revenues from those foreign currency sales, when translated into United States dollars, would increase. Conversely, if the dollar were to strengthen against these currencies, our revenues from those foreign currency sales, when translated 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. We do not currently expect that, during the remainder of 2017, the amount of our revenues conducted in these foreign currencies will fluctuate significantly from prior year levels. Given the historical and expected future level of sales made in foreign currencies, we do not currently plan to hedge against these currency rate fluctuations. However, if the portion of our revenues conducted in foreign currencies were to grow significantly, we would re-evaluate these exposures and, if necessary, enter into hedging arrangements to help minimize these risks.

In October 2006, we entered into a development and supply agreement with Enel. The development and supply agreement expired in March 2016. Under the development and supply agreement, Enel purchased metering kit products from us. Enel Project revenues recognized during the three and six months endedJune 30, 2016 were driven primarily by shipments of metering kits under the development and supply agreement.

We sold our products to Enel and its designated manufacturers in U.S. dollars. Therefore, the associated revenues are not subject to foreign currency risks. We do not currently expect that there will be any significant shipments to Enel in 2017. As such, we expect our revenues from Enel will decrease significantly in 2017 as compared to 2016.

Gross Profit and Gross Margin

Gross Profit	$8,999	$9,488	$	(489	)	(5.2	)%
Gross Margin	56.9%	56.8%	NA			0.1

Gross profit is equal to revenues less cost of revenues. Cost of revenues associated with sales of our 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 sales of our services includes employee-related costs such as salaries and fringe benefits as well as other direct and indirect costs incurred in providing training and customer support. Gross margin is equal to gross profit divided by revenues.

Our gross margins decreased by 1.2 percentage points for the three months ended June 30, 2017, as compared to the same period in 2016, and remained relatively unchanged for the six months ended June 30, 2017, as compared to the same period in 2016. The decrease between the two quarterly periods was primarily due to an increase in the amount of indirect costs incurred during the quarter ended June 30, 2017.

20

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.

Product Development	$	4,482	$	4,178	$	304	7.3	%

Product development expenses consist primarily of payroll and related expenses for development personnel, facility costs, expensed material, fees paid to third party service providers, depreciation and amortization, and other costs associated with the development of new technologies and products.

Our product development expenses increased by 14% and 7% during the three and six months ended June 30, 2017, respectively, as compared to the same periods in 2016. In both periods, the increases are primarily attributable to increased spending for third party contract engineers and consultants. In addition, non-cash equity compensation charges for equity awards granted to our product development personnel increased by $78,000 and $203,000 for the three and six months ended June 30, 2017, respectively, as compared to the same periods in 2016. We expect our equity compensation expenses will be higher for the duration of 2017 than they were in 2016.

Sales and marketing expenses consist primarily of payroll, commissions, and related expenses for sales and marketing personnel, travel and entertainment, facilities costs, advertising and product promotion, and other costs associated with our sales and marketing activities.

Our sales and marketing expenses decreased by 13% during the three months ended June 30, 2017 as compared to the same period in 2016, and remained relatively unchanged during the six months ended June 30, 2017 as compared to the same period

21

in 2016. The reduction between the two quarterly periods was primarily attributable to a reduction in compensation related expenses, in particular commissions paid to our sales force.

General and Administrative

General and Administrative	$	3,853	$	4,208	$	(355	)	(8.4	)%

General and administrative expenses consist primarily of payroll and related expenses for executive, finance, and administrative personnel, professional fees for legal and accounting services rendered to the company, facility costs, insurance, and other general corporate expenses.

Our general and administrative expenses decreased by 12% during the three months ended June 30, 2017 as compared to the same period in 2016. This decrease was primarily driven by a reduction in compensation related expenses as well as a reduction in fees paid to third party service providers, including our registered independent accountants.

During the six months ended June 30, 2017, our general and administrative expenses decreased by 8% as compared to the same period in 2016. Included in our results for the six months ended June 30, 2016 was a reduction of the contingent consideration we would owe to the former Lumewave shareholders. During the quarter ended March 31, 2016, we concluded that it was no longer probable that we would owe any further contingent consideration to the former Lumewave shareholders at the conclusion of the two-year period ending in August 2016. As a result, we reduced this accrual by the remaining $318,000 balance, which was recorded as a reduction to our general and administrative expenses. Excluding this reduction, our general and administrative expenses decreased by $673,000, which was driven in large part by a reduction of fees paid to third party service providers, as well as lesser reductions in fees paid to our Board of Directors, bank fees, insurance premiums, and compensation costs for our general and administrative personnel.

Partially offsetting the reductions in our general and administrative expenses during the first half of 2017 were higher non-cash charges for equity compensation awards granted to our general and administrative personnel. During the three and six months ended June 30, 2017, these equity compensation expenses increased by $130,000 and $232,000, respectively, as compared to the same periods in 2016. We expect the equity compensation expenses associated with our general and administrative personnel will continue to be higher for the remainder of 2017 as compared to 2016.

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 expense, net, increased by $723,000 and $583,000 during the three and six months ended June 30, 2017, respectively, as compared to the same periods in 2016. This fluctuations were primarily attributable to foreign currency exchange losses. During the second quarter of 2017, we recognized approximately $253,000 of foreign currency translation losses, whereas in the second quarter of 2016, we recognized foreign currency translation gains of approximately $486,000. Similarly, during the six months ended June 30, 2017, we recognized $341,000 of foreign currency translation losses, whereas during the same period in 2016, we recognized foreign currency translation gains of $265,000. These fluctuations are primarily 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 condensed 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 as we expect interest rates to remain historically low. Future gains or losses associated with translating our foreign currency denominated short-term intercompany balances will depend on exchange rates in effect at the time of translation.

Income tax expense for the three months ended June 30, 2017 was $29,000 compared to $51,000 for the same period in 2016, and was $23,000 for the six months ended June 30, 2017 compared to $57,000 for the same period in 2016. 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.

OFF-BALANCE-SHEET ARRANGEMENTS AND OTHER CONTRACTUAL OBLIGATIONS

Off-Balance-Sheet Arrangements. 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.

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.

23

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 cost of revenues in our condensed consolidated statements of operations, was approximately $80,000 and $160,000 for the three and six months endedJune 30, 2017, respectively, and $84,000 and $140,000 for the same period in 2016.

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 June 30, 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 are subject to 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 June 30, 2017, it is possible that our results of operations, cash flows, and financial position could be harmed by the resolution of any such outstanding claims.

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 flows.

The following table presents selected financial information as of June 30, 2017, and for each of the last three fiscal years (dollars in thousands):

	June 30,		December 31,

* As of June 30, 2017 and December 31, 2016, includes $1.3 million of restricted investments presented separately on condensed consolidated balance sheet

As of June 30, 2017, we had $21.0 million in cash, cash equivalents, restricted cash and short-term investments, a decrease of $2.1 million as compared to December 31, 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 by our employees and directors, and the exercise of warrants. 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, and purchases under our stock repurchase programs.

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 stock-based compensation, depreciation, and amortization; changes in accrued investment income; and fluctuations in operating asset and liability balances. Net cash used in operating activities was $2.1 million for the six months ended June 30, 2017, an increase in cash outflows of approximately $322,000 as compared to the same period in 2016. During the six months ended June 30, 2017, net cash used in operating activities was primarily the result of our net loss of $2.6 million, and changes in our operating assets and liabilities of $616,000; partially offset by stock-based compensation expenses of $909,000, and depreciation and amortization expense of $220,000. The primary components of the $616,000 net change in our operating assets and liabilities were a $668,000increase in accounts receivable, a $398,000increase in other current assets, a $111,000decrease in accrued liabilities, and a $111,000increase in deferred cost of revenues; all of which was partially offset by a $544,000increase in accounts payable and a $226,000increase in deferred revenues. Accounts receivable increased primarily as a result of the timing of shipments to and corresponding collections from our customers during the first six months of 2017. Other current assets increased primarily as a result of an increase in prepaid expenses. Accrued liabilities decreased primarily due to the payment of bonuses that were accrued as of December 31, 2016. Deferred cost of revenues increased due to an increase in our deferred revenues and the mix of products for which revenue was deferred at June 30, 2017. Accounts payable increased due to the timing of receipt and payment of invoices we received from our vendors during the period. Deferred revenues increased in accordance with the overall activity of our suppliers in all regions.

During the six months ended June 30, 2016, net cash used in operating activities of $1.8 million was primarily the result of our net loss of $1.6 million, a reduction in the expected amount of contingent consideration we expect to owe the former Lumewave shareholders of $318,000, and decreases in operating assets and liabilities of $244,000; partially offset by depreciation and amortization expense of $261,000 and stock-based compensation expenses of $176,000. The primary components of the $244,000 net decrease in our operating assets and liabilities were a $1.0 million decrease in accrued liabilities, a $791,000 decrease in accounts payable, and a $230,000 increase in deferred cost of goods sold; partially offset by a $1.0 million increase in deferred revenues, a $364,000 decrease in accounts receivable, and $219,000 decrease in other current assets. Accrued liabilities decreased primarily to the payment of bonuses that were accrued as of December 31, 2015.Accounts payable decreased due to the timing of receipt and payment of invoices we received from our vendors during the period. Deferred revenues and the associated deferred cost of goods sold increased in accordance with the overall activity with distributors in all regions. Accounts receivable decreased primarily as a result of the timing of shipments to and the corresponding collections from our customers in the first six months of 2016. Other current assets decreased primarily as a result of 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 provided by investing activities was $43,000 for the six months ended June 30, 2017, a decrease in cash inflows of $4.9 million from the same period in 2016. During the six months ended June 30, 2017, net cash provided by investing activities was primarily the result of proceeds from maturities and sales of available-for-sale short-term investments of $12.0 million, partially offset by purchases of available-for-sale short-term investments of $12.0 million, and capital expenditures of $31,000.

25

During the six months ended June 30, 2016, net cash provided by investing activities of $4.9 million was primarily the result of proceeds from maturities and sales of available-for-sale short-term investments of $13.0 million, partially offset by purchases of available-for-sale short-term investments of $8.0 million, and capital expenditures of $67,000.

Cash flows from financing activities. Cash flows from financing activities have historically been driven by the proceeds from issuance of common and preferred stock offset by transactions under our stock repurchase programs and principal payments on our lease financing obligations. Net cash used in financing activities was $64,000 for the six months ended June 30, 2017, a increase in cash outflows of $32,000 as compared to the same period in 2016. During the six months ended June 30, 2017, net cash used in financing activities was primarily the result of $64,000 worth of shares repurchased from employees for payment of employee taxes on vesting of performance shares.

During the six months ended June 30, 2016, net cash used in financing activities was the result of $32,000 worth of shares repurchased from employees for payment of employee taxes on vesting of performance shares.

As noted above, our cash and investments totaled $21.0 million as of June 30, 2017. 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.

We 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 condensed consolidated balance sheets).

In the future, our cash reserves may be used to strategically acquire or invest in other companies, products, or technologies that are complementary to our business. 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 Quarterly Report in the section titled “Factors That May Affect Future Results of Operations.” 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, and short-term investment balance will decline during the remainder of 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.

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 we entered into the stock purchase agreement with Enel, we 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, we cooperated with Enel to integrate our LONWORKS technology into Enel’s remote metering management project in Italy, the Contatore Elettronico. We completed the sale of our components and products for the deployment phase of the Contatore Elettronico project during 2005. During 2006, we supplied Enel and its designated manufacturers with limited spare parts for the Contatore Elettronico system. In October 2006, we entered into a new development and supply agreement and a software enhancement agreement with Enel.

26

Under the development and supply agreement, Enel and its contract manufacturers purchase additional electronic components and finished goods from us. Under the software enhancement agreement, we 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.

For the three months ended June 30, 2017 and 2016, as well as the six months endedJune 30, 2017, the Company recognized no revenue from products and services sold to Enel and its designated manufacturers. For the six months endedJune 30, 2016, the Company recognized revenue from products sold to Enel and its designated manufacturers of approximately $1.3 million. As of June 30, 2017 and December 31, 2016, none of the Company’s total accounts receivable balance related to amounts owed by Enel and its designated manufacturers.

RECENTLY ISSUED ACCOUNTING STANDARDS

During the six months ended June 30, 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 Condensed Consolidated Financial Statements in Part I, Item 1 of this report, that are of significance, or potential significance, to our company.

FACTORS THAT MAY AFFECT FUTURE RESULTS OF OPERATIONS

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 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 included in this Quarterly Report on Form 10-Q.

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.

We have decided to focus predominantly 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 releases of private 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);

27

• 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.

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 the last several years, we have experienced a decline in revenues from our legacy embedded systems products and services, including a cessation 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 forecast our future operating results 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. 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 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;

28

• 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. If we are unable to compete effectively in any of the markets we serve, our revenues, results of operations, and financial position would be harmed.

The sales cycle for our products is often lengthy and unpredictable.

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, which, if successful, can lead to one or more projects that deploy our lighting control solution. For larger projects, this 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.

In addition, potential customers for our products, both embedded systems and outdoor lighting 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 is subject to a number of significant risks that are beyond our control. Consequently, if our forecasted customer orders are not realized, our revenues could be materially adversely affected. In addition, the extended sales cycle may result in our inability to recognize revenue from existing or new projects until the end

29

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 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. 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.

We intend to continue investing resources in our development activities, which will expose us to risks, such as protection of intellectual property, investment risk, and labor costs and other matters. We could also be adversely affected by delays or cost increases experienced by third parties that are developing products on our behalf.

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. 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.

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.

Our market share in our existing embedded systems business has declined due to increased competition, reduced levels of investment in our LONWORKS product line, and pricing pressures faced around the world. Moreover, recent revenues generated from our embedded systems business have failed to meet our expectations. We expect this trend to continue for the foreseeable future, which could cause our operating results to suffer to the extent we are not able to generate offsetting revenues and gross profit through the sale of our control networking solutions for the outdoor lighting market. If this market share loss were to accelerate, 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 acceptance of our products in the IIoT market, particularly the outdoor lighting market, in order to increase our revenues;

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

• 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.

30

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. We may also be negatively impacted by employee turnover or other challenges that these third-party developers face in their own businesses. 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.

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.

31

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:

• 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 business depends on the Internet and its continued 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.

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.

32

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 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.  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 technologies, products or the systems with adequate security policies 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, or other unauthorized tampering or modification. Should our products fail to perform, or be unable to withstand a cyber-attack, 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.

Furthermore, because some of the information collected by some of our solutions, is or could be considered confidential consumer information in some jurisdictions, a cyber-attack could cause a violation of applicable privacy, consumer or security laws, which could cause our company to face financial or legal liability, should a security breach occur, which could have a material adverse effect on the Company.

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 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.

33

Because our products use components or materials that may 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 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 recently reduced our inventory 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 operating results. 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.

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;

• inherent challenges in managing international operations;

• the burdens of complying with a wide variety of foreign laws and any related implementation costs; the applicability of foreign laws that could affect our business or revenues, such as laws that purport to require that we return payments that we received from insolvent customers in certain circumstances; and unexpected changes in regulatory requirements, tariffs, and other trade barriers;

• inherent cultural differences that could make it more difficult to sell our products or could result in allegations that sales activities have violated the U.S. Foreign Corrupt Practices Act or similar laws that prohibit improper payments in connection with efforts to obtain business;

• 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.

Adverse changes in general economic or political conditions in any of the major countries in which we do business could adversely affect our business or operating results.

Our business can be affected by a number of factors that are beyond our control, such as general geopolitical, economic, and business conditions. In addition, political uncertainty in the countries where we seek to do business may impact the timing, as well as our ultimate ability, of obtaining new customers and implementing new systems.

In addition, there could be a number of follow-on effects from the credit crisis on our business, such as the insolvency of certain of our key customers, which could impair our distribution channels or result in the inability of our customers to obtain credit to finance purchases of our products.

34

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.

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.

35

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 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 NIST. 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.

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

36

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.

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.

37

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, 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.

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.

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.

38

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.

39

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. If such efforts against us were to be successful, it 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 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.

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

40

We must protect our business and our network infrastructure against damage from earthquake, flood, hurricane and similar events, as well as from power outages. 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. 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 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS

We have not experienced any material change in our exposure to interest rate and foreign currency risks since the date of our Annual Report on Form 10-K for the year ended December 31, 2016.

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 June 30, 2017 and December 31, 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 June 30, 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 4.    CONTROLS AND PROCEDURES

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 Quarterly Report on Form 10-Q, 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

41

evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of June 30, 2017.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(e) of the Exchange Act) that occurred during the quarter ended June 30, 2017, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Basis of Presentation

The condensed consolidated financial statements include the accounts of Echelon Corporation, a Delaware corporation, its wholly-owned subsidiaries, and a subsidiary in which it has a controlling interest (collectively referred to as the “Company”). The Company reports non-controlling 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.

While the financial information furnished is unaudited, the condensed consolidated financial statements included in this report reflect all adjustments (consisting only of normal recurring adjustments) which the Company considers necessary for the fair presentation of the results of operations for the interim periods covered, and of the financial condition of the Company at the date of the interim balance sheet. The results for interim periods are not necessarily indicative of the results for the entire year. The condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements for the year ended December 31, 2016 included in its Annual Report on Form 10‑K.

There have been no material changes to the Company’s significant accounting policies as compared to the significant accounting policies described in its Annual Report on Form 10‑K for the fiscal year ended December 31, 2016.

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 29.1% of revenues for the six months ended June 30, 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.

• In an effort to manage costs and inventory risks, the Company has decreased the inventory levels of certain products. If there is an unexpected increase in demand for these items, the Company might not be able to supply its 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 Condensed Consolidated Financial Statements and accompanying notes. Significant estimates and judgments are used for revenue recognition, performance-based equity compensation, inventory valuation, intangible asset valuation, contingent consideration valuation, allowance for warranty costs, 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. There was no impact on the Company's financial statements as a result of the adoption.

(ii) New Accounting Standards Not Yet Effective

In 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.

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 currently anticipates adopting the standard using the full retrospective method to restate each prior reporting period presented.

The standard will be effective for Echelon in the fiscal year beginning January 1, 2018. The Company currently anticipates the standard will have a material impact on its financial statements and disclosures, and continues to make progress in assessing all potential impacts of the standard, including any impacts of recently issued amendments. 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 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 the distribution channel. During the year ended December 31, 2016, the Company recognized approximately $14.7 million of revenue sold through such distributors. As of December 31, 2016, the amount of revenue and cost of revenues sold through the distribution channel that were deferred was $2.6 million and $668,000, respectively.

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.   

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, in limited circumstances, software post-contract support services) and training.

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 certain 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.

Deferred Revenue and Deferred Cost of Revenues

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

Restricted Investments

As of June 30, 2017, restricted investments consist of balances maintained by the Company with an investment advisor in money market funds and permitted treasury bills. These balances represent collateral for a $1.0 million operating line of credit issued to the Company by its primary bank for credit card purchases. Because the Company’s agreement with the lender prevents the Company from withdrawing these funds, they are considered restricted.

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:

• 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 and liabilities required to be measured at fair value on a recurring basis at June 30, 2017, are its fixed income available-for-sale securities. See Note 2 of these Notes to condensed consolidated financial statements for a summary of the input levels used in determining the fair value of these assets and liabilities as of June 30, 2017.

Long-Lived Assets

We perform periodic reviews to determine whether facts and circumstances exist that would indicate that the carrying amounts of property, plant and equipment and long-lived intangible assets might not be fully recoverable. If facts and circumstances indicate that the carrying amount of these assets might not be fully recoverable, we compare projected undiscounted net cash flows associated with the related asset or group of assets over their estimated remaining useful lives against their respective carrying amounts. In the event that the projected undiscounted cash flows are not sufficient to recover the carrying value of the assets, the assets are written down to their estimated fair values based on the expected discounted future cash flows attributable to the assets. Evaluation of impairment of property, plant and equipment and long-lived intangible assets requires estimates in the forecast of future operating results that are used in the preparation of the expected future undiscounted cash flows. Actual future operating results and the remaining economic lives of our property, plant and equipment and long-lived intangible assets could differ from our estimates used in assessing the recoverability of these assets. These differences could result in impairment charges, which could have a material adverse impact on our results of operations. 

Contingent Consideration

During the quarter ended March 31, 2016, the contingent consideration payable to Lumewave's shareholders, which the Company recognized upon its purchase of Lumewave in August 2014, 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 condensed consolidated statements of operations.

Fair Value Disclosures [Abstract]

Financial Instruments

Financial Instruments:

The Company’s financial instruments consist of cash equivalents, restricted investments, short-term investments, accounts receivable, and accounts payable. 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, restricted investments, or short-term investments, and accounts receivable. 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 accounts receivable, 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 to mitigate the risk of uncollectibility, such as a bank guarantee. 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.

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 available-for-sale investments, 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 June 30, 2017 (in thousands):

	Fair Value Measurements at Reporting Date Using
			Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Inputs		Significant Unobservable Inputs
	Total		(Level 1)		(Level 2)		(Level 3)

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

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

Cash equivalents consist of either investments with remaining maturities of three months or less at the date of purchase, or money market funds for which the carrying amount is a reasonable estimate of fair value.

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 by comparing prices obtained from a third party independent source.

As of June 30, 2017, the Company’s available-for-sale securities had contractual maturities of six months and an average remaining term to maturity of three months. As of June 30, 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):

	Amortized Cost		Aggregate Fair Value		Unrealized Holding Gains		Unrealized Holding Losses
U.S. government securities	$	11,970	$	11,968	$	—	$	2

The amortized cost basis, aggregate fair value and gross unrealized holding gains and losses for the Company’s available-for-sale short-term investments, by major security type, were as follows as of December 31, 2016 (in thousands):

	Amortized Cost		Aggregate Fair Value		Unrealized Holding Gains		Unrealized Holding Losses
U.S. government securities	$	11,984	$	11,983	$	—	$	1

Market values were determined for each individual security in the investment portfolio. 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 negative expense amounts reflected in the table above are primarily due to the reversal of previously recognized expense resulting from the forfeiture of equity awards for certain employees whose employment terminated during the respective periods.

Stock Award Activity

There were no options exercised during the three and six months endedJune 30, 2017 and 2016.

The total fair value of RSUs vested and released during the three and six months ended June 30, 2017 was $147,000 and $196,000, respectively. The total fair value of RSUs vested and released during the three and six months ended June 30, 2016 was approximately $92,000 and $96,000, respectively. The fair value is calculated by multiplying the fair market value of the Company’s common stock on the vesting date by the number of shares of common stock issued upon vesting.

Commitments and Contingencies:

Legal Actions

From time to time, in the ordinary course of business, the Company may be subject to certain legal proceedings, claims, investigations, and other proceedings, including claims of alleged infringement of third-party patents and other intellectual property rights, and commercial, employment, or 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 June 30, 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

As of June 30, 2017, the Company maintained 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 condensed consolidated balance sheets). The restricted investments are classified as current assets due to the contractual duration of the underlying credit agreement.

Segment Reporting [Abstract]

Segment Disclosure

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). The Company operates in one principal industry segment - the IIoT segment, which is its reportable segment.

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 and other assets include property and equipment, acquired intangible assets, 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 June 30, 2017 and December 31, 2016, long-lived assets of approximately $2.0 million and $2.2 million, respectively, were domiciled in the United States. Long-lived assets for all other locations are not material to the condensed 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, value-added resellers, and local distributors, primarily in EMEA and APJ. 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 three and six months endedJune 30, 2017 and 2016 is as follows (in thousands):

Income Taxes

Income Taxes:

The provision for income taxes for the three months ended June 30, 2017 and 2016 was $29,000 and $51,000, respectively. The provision for income taxes for the six months endedJune 30, 2017 and 2016 were $23,000 and $57,000, respectively. The difference between the statutory rate and the Company’s 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.

As of June 30, 2017 and December 31, 2016, the Company had gross unrecognized tax benefits of approximately $9.3 million and $9.2 million, respectively, of which $357,000 and $364,000, respectively, if recognized, would impact the effective tax rate on income from continuing operations. The Company’s policy is to recognize interest and/or penalties related to unrecognized tax benefits in income tax expense. As of June 30, 2017 and December 31, 2016, the Company had accrued $52,000 and $62,000, respectively, for interest and penalties. The $10,000 reduction in interest and penalties on gross unrecognized tax benefits during the six months ended June 30, 2017 was primarily attributable to the expiration of the statute of limitations in certain foreign jurisdictions.

In June 2000, the Company entered into a stock purchase agreement with Enel pursuant to which Enel purchased 300,000 newly issued shares of its 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 the Company’s knowledge, Enel has disposed of none of its 300,000 shares. Under the terms of the stock purchase agreement, Enel has the right to nominate one member of the Company’s board of directors. While a representative of Enel served on the board until March 14, 2012, no Enel representative is presently on the board.

In October 2006, the Company entered into a new development and supply agreement with Enel. Under the development and supply agreement, Enel and its contract manufacturers purchase additional electronic components and finished goods from the Company. The development and supply agreement expired in March 2016.

For the three and six months ended June 30, 2017, the Company recognized no revenue from products sold to Enel and its designated manufacturers. For the three and six months ended June 30, 2016, the Company recognized revenue from products sold to Enel and its designated manufacturers of approximately $0 and $1.3 million, respectively.

Joint Venture

Joint Venture:

On March 23, 2012, the Company entered into an agreement with Holley Metering Limited (“Holley Metering”), a designer and manufacturer of energy meters in China, to create a joint venture, Zhejiang Echelon-Holley Technology Co., Ltd. (“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 51.0% ownership interest in the joint venture and exercises controlling influence. Therefore, Echelon-Holley’s accounts are included in the Company’s condensed consolidated financial statements as of June 30, 2017 and 2016, and for the six months then ended. Holley Metering’s interests in Echelon-Holley’s net assets are reported in the non-controlling interest in subsidiary on the condensed consolidated balance sheet as of June 30, 2017. Net loss attributable to the non-controlling interest in Echelon-Holley was $0 and $0 during the three and six months endedJune 30, 2017 and 2016, respectively.

As of June 30, 2017, Echelon and Holley Metering had contributed in cash a total of approximately $4.0 million in Share Capital, as defined in the joint venture agreement, to Echelon-Holley in proportion to their respective ownership interests.

In connection with the decision to sell the Grid business announced in the third quarter of 2014, the Company undertook a process to sell the remaining net assets of the joint venture and recorded the net assets and liabilities of the joint venture at the lower of their carrying amount or fair value less cost to sell, and classified them as held for sale on the accompanying balance sheet at December 31, 2014. The major classes of assets and liabilities that were classified as held for sale were inventory, deferred revenues and the related deferred costs of sales, and accrued liabilities.

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 of June 30, 2017, the Company is continuing to work with Holley Metering to complete the shut-down.

Summary of Significant Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The condensed consolidated financial statements include the accounts of Echelon Corporation, a Delaware corporation, its wholly-owned subsidiaries, and a subsidiary in which it has a controlling interest (collectively referred to as the “Company”). The Company reports non-controlling 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.

While the financial information furnished is unaudited, the condensed consolidated financial statements included in this report reflect all adjustments (consisting only of normal recurring adjustments) which the Company considers necessary for the fair presentation of the results of operations for the interim periods covered, and of the financial condition of the Company at the date of the interim balance sheet. The results for interim periods are not necessarily indicative of the results for the entire year. The condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements for the year ended December 31, 2016 included in its Annual Report on Form 10‑K.

There have been no material changes to the Company’s significant accounting policies as compared to the significant accounting policies described in its Annual Report on Form 10‑K for the fiscal year ended December 31, 2016.

Risks and Uncertainties

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 29.1% of revenues for the six months ended June 30, 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.

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

Use of Estimates

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 Condensed Consolidated Financial Statements and accompanying notes. Significant estimates and judgments are used for revenue recognition, performance-based equity compensation, inventory valuation, intangible asset valuation, contingent consideration valuation, allowance for warranty costs, 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

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. There was no impact on the Company's financial statements as a result of the adoption.

(ii) New Accounting Standards Not Yet Effective

In 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.

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 currently anticipates adopting the standard using the full retrospective method to restate each prior reporting period presented.

The standard will be effective for Echelon in the fiscal year beginning January 1, 2018. The Company currently anticipates the standard will have a material impact on its financial statements and disclosures, and continues to make progress in assessing all potential impacts of the standard, including any impacts of recently issued amendments. 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 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 the distribution channel. During the year ended December 31, 2016, the Company recognized approximately $14.7 million of revenue sold through such distributors. As of December 31, 2016, the amount of revenue and cost of revenues sold through the distribution channel that were deferred was $2.6 million and $668,000, respectively.

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

Revenue Recognition

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, in limited circumstances, software post-contract support services) and training.

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 certain 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.

Deferred Revenue and Deferred Cost of Revenue

Deferred Revenue and Deferred Cost of Revenues

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

Restricted Investments

Restricted Investments

As of June 30, 2017, restricted investments consist of balances maintained by the Company with an investment advisor in money market funds and permitted treasury bills. These balances represent collateral for a $1.0 million operating line of credit issued to the Company by its primary bank for credit card purchases. Because the Company’s agreement with the lender prevents the Company from withdrawing these funds, they are considered restricted.

Fair Value Measurements

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:

• 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 and liabilities required to be measured at fair value on a recurring basis at June 30, 2017, are its fixed income available-for-sale securities. See Note 2 of these Notes to condensed consolidated financial statements for a summary of the input levels used in determining the fair value of these assets and liabilities as of June 30, 2017.

Long-Lived Assets

Long-Lived Assets

We perform periodic reviews to determine whether facts and circumstances exist that would indicate that the carrying amounts of property, plant and equipment and long-lived intangible assets might not be fully recoverable. If facts and circumstances indicate that the carrying amount of these assets might not be fully recoverable, we compare projected undiscounted net cash flows associated with the related asset or group of assets over their estimated remaining useful lives against their respective carrying amounts. In the event that the projected undiscounted cash flows are not sufficient to recover the carrying value of the assets, the assets are written down to their estimated fair values based on the expected discounted future cash flows attributable to the assets. Evaluation of impairment of property, plant and equipment and long-lived intangible assets requires estimates in the forecast of future operating results that are used in the preparation of the expected future undiscounted cash flows. Actual future operating results and the remaining economic lives of our property, plant and equipment and long-lived intangible assets could differ from our estimates used in assessing the recoverability of these assets. These differences could result in impairment charges, which could have a material adverse impact on our results of operations.
