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;">Over the past few years we have exited non-core businesses to focus our efforts on TLED products, starting with the sale of our pool lighting products business in 2013. During 2015 we exited our turnkey solutions business operated by our subsidiary, Energy Focus LED Solutions, LLC (“EFLS”), and exited our United Kingdom business through the sale of Crescent Lighting Limited (“CLL”), our wholly-owned subsidiary. As a result, we have reclassified all net sales and expenses associated with both EFLS and CLL from the Consolidated Statements of Operations and have reported the related net income (loss) as discontinued operations. Please refer to Note 4, “Discontinued Operations,” for more information on our disposition of these businesses.</font><font style="font-family:inherit;font-size:10pt;"> </font></div><div style="line-height:120%;text-align:left;text-indent:10px;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;">Given the decline in our military maritime business, the changing competitive landscape of the U.S. Navy sales channel and the timing uncertainty of commercial sales growth, we implemented a restructuring initiative during the first quarter of 2017. The intent of the restructuring strategy was to maximize operating cost reductions without sacrificing either our new product pipeline or potential long-term revenue growth and return the Company to profitability. On February 19, 2017, the Board appointed Dr. Ted Tewksbury to serve as the Company’s Chairman of the Board, Chief Executive Officer and President to lead the Company’s restructuring efforts. Dr. Tewksbury, who holds M.S. and Ph.D. degrees in Electrical Engineering from MIT, is a well-seasoned semiconductor industry executive with experience in implementing and managing successful business restructurings.</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%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The restructuring initiative included an organizational consolidation of management functions in order to streamline and better align the Company into a more focused, efficient, and cost-effective organization. The initiative also included the transition from our historical direct sales model, to an agency driven sales channel strategy in order to expand our market presence throughout the U.S. During 2017 we closed our New York, New York, Arlington, Virginia and Rochester, Minnesota offices, reduced full-time equivalent headcount by </font><font style="font-family:inherit;font-size:10pt;">51 percent</font><font style="font-family:inherit;font-size:10pt;"> and significantly decreased operating expenses from 2016 levels (a net reduction of </font><font style="font-family:inherit;font-size:10pt;">$8.4 million</font><font style="font-family:inherit;font-size:10pt;">, which includes </font><font style="font-family:inherit;font-size:10pt;">$1.8 million</font><font style="font-family:inherit;font-size:10pt;"> in offsetting restructuring and impairment charges). As of December 31, 2017, we had effectively transitioned our sales force to an agency driven sales channel, expanding 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 </font><font style="font-family:inherit;font-size:10pt;">30</font><font style="font-family:inherit;font-size:10pt;"> sales agents. As a result of this transition, we have substantially expanded from a primarily Midwest focus to build market presence and awareness in other regions of the U.S. with significant demand potential, including the Northeast, Southeast and California.</font></div></div>

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>
