We operate in a single industry segment, developing and selling our energy-efficient light-emitting diode (“LED”) lighting products into the general commercial, industrial and military maritime markets. Our goal is to become a trusted leader in the LED lighting retrofit market by replacing fluorescent lamps in institutional buildings and high-intensity discharge (“HID”) lighting in low-bay and high-bay applications with our innovative, high-quality commercial and military tubular LED (“TLED”) products.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The LED lighting industry has changed dramatically over the past several years due to increasing commoditization and price erosion. We experienced this in our Navy business in late 2016 and early 2017 and in our commercial segment, where we once enjoyed significant price premiums for our flicker-free TLEDs with 10-year warranties, we now have a number of competitors offering similar capabilities at much lower prices. During the year, we reduced the costs of eight legacy product families in order to price our products more competitively. Despite these efforts, the pricing of our legacy products remains at the high end of the competitive range and we expect aggressive price erosion and commoditization to continue to be a headwind until our more innovative and differentiated new products ramp in volume. These trends are not unique to Energy Focus as evidenced by the increasing number of industry peers facing challenges, exiting LED lighting, selling assets and even going out of business. In addition to continuous, scheduled cost reductions, our strategy to combat these trends it to move up the value chain, with more differentiated products and solutions, such as our smart lighting roadmap, that offer greater value to our customers. </font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"> </font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In light of these factors, over this period we have evaluated the continued value of equipment and inventory and implemented restructuring and product development initiatives to reduce costs and streamline operations while continuing to pursue our new product pipeline and revenue growth. During 2016, the slowdown in demand from U.S. Navy resulted in a year-over-year decrease in military maritime sales of </font><font style="font-family:inherit;font-size:10pt;">$33.9 million</font><font style="font-family:inherit;font-size:10pt;"> from 2015 to 2016.

As of December 31, 2018, we expanded our sales coverage to the entire U.S. through </font><font style="font-family:inherit;font-size:10pt;">six</font><font style="font-family:inherit;font-size:10pt;"> geographic regions and now have </font><font style="font-family:inherit;font-size:10pt;">50</font><font style="font-family:inherit;font-size:10pt;"> sales agencies, each of which has, on average, </font><font style="font-family:inherit;font-size:10pt;">10</font><font style="font-family:inherit;font-size:10pt;"> agents representing Energy Focus products. During 2017, we also implemented a strategic sales initiative to sell certain excess inventory that had previously been written-down, as required by U.S. GAAP. This initiative resulted in a net reduction of our excess inventory reserves of </font><font style="font-family:inherit;font-size:10pt;">$1.4 million</font><font style="font-family:inherit;font-size:10pt;"> in </font><font style="font-family:inherit;font-size:10pt;">2017</font><font style="font-family:inherit;font-size:10pt;">.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">During 2018, we recorded restructuring charges totaling approximately </font><font style="font-family:inherit;font-size:10pt;">$0.1 million</font><font style="font-family:inherit;font-size:10pt;">, related to the revision of our initial estimates of the costs and offsetting sublease income and accretion expense for the remaining lease obligation for our former New York, New York and Arlington, Virginia offices. As a result of our continued cost control initiatives in 2018, we achieved an additional net decrease in operating expenses of </font><font style="font-family:inherit;font-size:10pt;">$3.6 million</font><font style="font-family:inherit;font-size:10pt;">, which includes the </font><font style="font-family:inherit;font-size:10pt;">$0.1 million</font><font style="font-family:inherit;font-size:10pt;"> recorded in facility restructuring charges.

The substantial doubt about our ability to continue as a going concern continued to exist as of December 31, 2018.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Over the past several months, we have evaluated and pursed, and we expect that we will continue to assess the Company’s strategic options, as we seek additional external funding sources and to achieve a profitable business model and maximize value for our stockholders.

Estimates include, but are not limited to, the establishment of reserves for accounts receivable, sales returns, inventory obsolescence and warranty claims; the useful lives for property, equipment, and intangible assets; and stock-based compensation. In addition, estimates and assumptions associated with the determination of the fair value of financial instruments and evaluation of long-lived assets for impairment requires considerable judgment. Actual results could differ from those estimates and such differences could be material.</font></div></div>
