The Company

The Company	12 Months Ended

The Company	1. The Company Revolution Lighting Technologies, Inc., together with its wholly-owned subsidiaries (“Revolution”, “we”, “us” or “our”), is a leader in the de s Tri-State E-Lighting, All-Around We generate revenue by selling lighting products for use in the commercial, industrial and government markets, which include vertical markets such as military, municipal, commercial office, industrial, warehouse, education, hospitality, retail, healthcare, multi-family and signage-media-accent markets. We market and distribute our products globally through networks of distributors, independent sales agencies and representatives, electrical supply companies, as well as internal marketing and sales forces. Our operations consist of one reportable segment for financial reporting purposes: Lighting Products and Solutions (principally LED fixtures and lamps). Basis of presentation The consolidated financial statements included in this Form 10-K Use of estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The most significant estimates relate to valuation of receivables and inventories, purchase price allocation of acquired businesses, impairment of goodwill and long-lived assets, income taxes, and contingencies. It is at least reasonably possible that the effect on the financial statements of a change in estimate due to one or more future confirming events could have a material effect on the financial statements. Stock Split On March 10, 2016, we filed a certificate of amendment to our Amended and Restated Certificate of Incorporation, as amended, to effect a 1-for-10 Liquidity and Capital Resources On January 26, 2017, we amended the Revolving Credit Facility which enabled us to borrow up to $50.0 million on a revolving basis, based upon specified percentages of eligible receivables and inventory, which matures on January 26, 2020. See Note 9. Our liquidity as of December 31, 2017 and 2016 was $7.4 million and $1.9 million, respectively, which consisted of cash and cash equivalents of $0.9 million and $0.9 million, respectively, and additional borrowing capacity under the Revolving Credit Facility of $6.5 million and $1.0 million, respectively. Historically, our significant shareholder, RVL 1 LLC (“RVL”), and its affiliates have been a significant source of financing, and they continue to support our operations. See Note 17. At December 31, 2017 and 2016, we had working capital of $34.3 million and $51.3 million, respectively. We believe we have adequate resources to meet our cash requirements for the foreseeable future.

Significant Accounting Policies

Significant Accounting Policies	12 Months Ended
	Dec. 31, 2017
Significant Accounting Policies	2. Significant Accounting Policies Fair Value Measurement We measure fair value on a recurring basis utilizing valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs, to the extent possible, and consider counterparty credit risk in our assessment of fair value. The fair value hierarchy is as follows: Level 1 – Quoted prices in active markets for identical assets and liabilities; Level 2 – Quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active or other inputs that are observable or can be corroborated by observable market data; and Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. Cash and cash equivalents, trade and unbilled contract receivables, inventories, other current assets, accounts payable, and accrued and other liabilities are classified as Level 1 as their carrying values approximate fair value since they are short term in nature and they are receivable or payable on demand. Based on the borrowing rates currently available for bank loans with similar terms and average maturities, the fair value of notes payable are equal to the carrying value. As such, notes payable are classified as Level 1. See Notes 9 and 17. The estimated fair value of the reporting unit in our goodwill impairment assessment utilized the market approach based on inputs that are readily available from public markets or can be derived from observable market transactions, and have been classified as level 2 in the fair value hierarchy. The fair values of intangible assets in our long-lived asset impairment assessment were established based on projected discounted cash flows, which were based on significant unobservable inputs and have been classified as Level 3 in the fair value hierarchy. The estimated fair value of assets and liabilities acquired in business combinations utilize inputs classified as Level 3 in the fair value hierarchy. Cash and Cash Equivalents We consider all investments with an original maturity of three months or less to be cash equivalents. We maintain cash and cash equivalents in bank accounts that may exceed federally insured limits. The financial institutions where our cash and cash equivalents are held are highly rated. We have not experienced any losses in such accounts, and believe we are not exposed to significant credit risk. Accounts Receivable Accounts receivable are customer obligations due under normal trade terms. We perform periodic credit evaluations of our customers’ financial condition. We record an allowance for doubtful accounts based upon factors surrounding the credit risk of certain customers, and specifically identified amounts that we believe to be uncollectible. Recovery of bad debt amounts previously written off is recorded as a reduction of bad debt expense in the period the payment is collected. If our actual collection experience changes, revisions to our allowance may be required. After all attempts to collect a receivable have failed, the receivable is written off against the allowance. See Note 3. Inventories Inventories are stated at the lower of cost (first-in, first-out) Property and Equipment Property and equipment, net is stated at cost (or fair value, if acquired as part of a business combination) less accumulated depreciation, and is depreciated over its estimated useful life using the straight-line method as follows: Machinery and equipment 3-7 Furniture and fixtures 5-7 Computers and software 3-7 Motor vehicles 5 years Leasehold improvement Lesser of lease term or estimated useful life Maintenance and repairs are expensed as incurred. Upon retirement or sale, the cost and related accumulated depreciation are removed from the respective account, and any resulting gain or loss is recognized in the Consolidated Statements of Operations. See Note 5. Goodwill Goodwill is not amortized, but is subject to annual impairment testing unless circumstances dictate more frequent assessments. We perform an annual impairment assessment for goodwill during the fourth quarter of each year or more frequently whenever changes in circumstances indicate that the fair value of the asset may be less than the carrying amount. We have one reporting unit for goodwill impairment testing purposes. In testing goodwill for impairment, we compare the fair value of the reporting unit to its carrying amount. The fair value of the reporting unit is determined by calculating our market capitalization at the impairment test day. If the fair value of the reporting unit is greater than its carrying amount, there is no impairment. If the carrying amount of goodwill exceeds the implied fair value of goodwill, an impairment loss is recognized in an amount equal to the excess. On October 1, 2017, we performed our annual goodwill impairment test and the estimated fair value exceeded carrying value. We concluded that goodwill, as of October 1, 2017, was not impaired . During the fourth quarter of 2017, we experienced poor performance of our stock price, which led management to believe that a triggering event occurred. As such, an updated goodwill impairment test was performed. Because we elected to early adopt Accounting Standards Update (“ASU”) 2017-04, Simplifying the Test for Goodwill Impairment Intangible Assets Intangible assets, net is stated at cost or fair value, if acquired as part of a business combination, less accumulated amortization, and is amortized over its estimated useful life using the straight-line method as follows: Customer relationships 10-15 Trademarks and trade names 12-17 Non-compete 6 years Favorable leases 10 years We evaluate the recoverability of the carrying value of long-lived assets whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The long-lived asset is grouped with other assets at the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. We assess whether the projected undiscounted cash flows of our long-lived assets are sufficient to recover the carrying amount of the asset group being assessed. If the undiscounted projected cash flows are less than the carrying value of the assets, we calculate an impairment by comparing the carrying value of the asset group to its fair value. The amount of the impairment of long-lived assets is written off against earnings in the period in which the impairment is determined. During the fourth quarter of 2017, management performed an impairment test on certain long-lived asset groups. The result of the impairment test indicated that certain intangible assets were impaired by $10.5 million. See Note 7. Purchase Price Obligations In connection with certain prior acquisitions, we are obligated to issue contingent consideration. We determine the fair value of certain purchase price obligations on a recurring basis based on a probability-weighted discounted cash flow analysis and Monte Carlo simulation. The fair value remeasurement is based on significant inputs not observable in the market and thus represents a Level 3 measurement. On a quarterly basis, we reassess our current estimates of performance relative to the stated targets and adjust the liability to fair value. Any such adjustments are included in “Acquisition, severance and transition costs” in the Consolidated Statements of Operations. See Note 10. Contingencies In accordance with Accounting Standards Codification (“ASC”) 450, Contingencies Revenue Recognition We recognize revenue from our product sales upon shipment or delivery to customers in accordance with the respective contractual arrangements, provided no significant obligations remain and collection is probable. For sales that include customer acceptance terms, revenue is recorded after customer acceptance at the applicable location. It is our policy that all sales are final. Requests for returns are reviewed on a case by case basis. As revenue is recorded, we accrue an estimated amount for product returns as a reduction of revenue. We recognize revenue from fixed-price and modified fixed-price contracts for turnkey energy conservation projects using the percentage-of-completion percentage-of-completion See “ Recent accounting pronouncements Warranties and product liability Our products typically carry a warranty that ranges from one to ten years and includes replacement of defective parts. A warranty reserve is recorded for the estimated costs associated with warranty expense related to recorded sales, which is included within accrued liabilities. We recorded warranty expense of $0.2 million for each of the years ended December 31, 2017, 2016 and 2015, which was included in “Selling, general and administrative” in the Consolidated Statements of Operations. At both December 31, 2017 and 2016, we had recorded a warranty and product liability of $0.4 million in the Consolidated Balance Sheets. Sales Tax Revenue We record sales tax revenue on a gross basis (included in both “Revenues” and “Cost of sales” in the Consolidated Statements of Operations). For the years ended December 31, 2017, 2016 and 2015, revenues from sales taxes were $4.1 million, $5.2 million and $4.5 million, respectively. Shipping and Handling Shipping and handling costs related to the acquisition of goods from vendors are included in cost of sales. Research and Development Research and development costs to develop new products, which consist of salaries, contractor fees, building cost, utilities, administrative expenses and allocations of corporate costs, are charged to expense as incurred. Advertising Expense Advertising costs, included in “Other selling, general and administrative” on the Consolidated Statements of Operations are expensed when the advertising first takes place. We promote our product lines through print media and trade shows, including trade publications and promotional brochures. Advertising expense was $0.3 million, $0.2 million and $0.3 million for the years ended December 31, 2017, 2016 and 2015, respectively. Income taxes Income taxes are provided for the tax effects of transactions reported in the financial statements and consist of taxes currently due plus deferred taxes resulting from temporary differences. Such temporary differences result from differences in the carrying value of assets and liabilities for tax and financial reporting purposes. The deferred tax assets and liabilities represent the future tax consequences of those differences, which will either be taxable or deductible when the assets and liabilities are recovered or settled. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. We applied the provisions of ASC 740, Income Taxes We evaluate the adequacy of the valuation allowance quarterly and, if our assessment of whether it is more likely than not that the related tax benefits will be realized changes, the valuation allowance will be increased or reduced with a corresponding benefit or charge included in income. In December 2017, the U.S., enacted the Tax Cuts and Jobs Act (“TCJA”), which made significant changes to U.S. federal income tax law. Shortly after enactment of the TCJA, the United States Securities and Exchange Commission’s (the “SEC”) staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), which provides guidance on accounting for the impact of the TCJA. Under SAB 118, an entity would use a similar approach as the measurement period provided in the Business Combinations Topic of the ASC. An entity will recognize those matters for which the accounting can be completed. For matters that have not been completed, the entity would either (1) recognize provisional amounts to the extent that they are reasonably estimable and adjust them over time as more information becomes available or (2) for any specific income tax effects of the TCJA for which a reasonable estimate cannot be determined, continue to apply the Income Taxes Topic of the ASC on the basis of the provisions of the tax laws that were in effect immediately before the TCJA was signed into law. We have prepared our consolidated financial statements for the fiscal year ended December 31, 2017 in accordance with the Income Taxes Topic of the ASC as allowed by SAB 118. See Note 13. Loss per Share Basic loss per share is computed by dividing net loss attributable to common stockholders by the weighted average common shares outstanding for the period. Diluted loss per share is computed giving effect to all potentially dilutive common shares. Potentially dilutive common shares consist of incremental shares issuable upon the exercise of stock options and vesting of restricted shares and the conversion of outstanding convertible securities. In periods in which a net loss has been incurred, all potentially dilutive common shares are considered anti-dilutive and thus are excluded from the calculation. See Note 14. Stock-Based Compensation Restricted Stock and Restricted Stock Unit Awards (Equity) Restricted Stock Awards (Liability) non-employee Equity-Based Payments to Non-Employees re-measured Option Awards Business Acquisitions Business acquisitions are accounted for using the acquisition method of accounting, which requires recording assets acquired and liabilities assumed at fair value of the acquisition date. Under the acquisition method of accounting, each tangible and separately identifiable intangible asset acquired and liability assumed is recorded based on their preliminary estimated fair values on the acquisition date. Acquisition related costs are expensed as incurred, and are included in “Acquisition, severance and transition costs” in the Consolidated Statements of Operations. See Note 19. Recent accounting pronouncements not yet adopted In May 2014, the Financial Accounting Standards Board (the “FASB”) issued ASU 2014-09, Revenue from Contracts with Customers 2014-09, We have identified that the main types of contracts that require evaluation as to what, if any, changes will be necessary under ASC 606 as compared to legacy accounting guidance are (a) product sales that are shipped to customers from either our warehouses or directly from our vendors and (b) contracts that involve a combination of product and installation services. We have evaluated the provisions of ASC 606 against our existing accounting policies and practices, including reviewing standard purchase orders, invoices, shipping terms, and agreements with customers to determine the impact, if any, on the timing, measurement and presentation of revenue recognition and the cost of sales. The review considered, among other matters, the evaluation and identification of distinct performance obligations and the measurement of our progress toward satisfying identified performance obligations. We determined that the adoption of ASC 606 will not impact the timing of our billings to customers or the receipt of customer payments. Under ASC 606, incremental contract costs, which includes sales commissions, are required to be capitalized as contract assets and amortized over the period these costs are expected to be recovered. Although we incur such costs, our contracts are typically completed within one year. As such, we have elected the practical expedient provided in ASC 606 and expense incremental contract costs when incurred. We have evaluated this standard and determined that the adoption of ASC 606 will not have a material effect on our financial statements. We have evaluated our processes and controls necessary for implementing this standard, including the increased disclosure requirements. In February 2016, the FASB issued ASU 2016-02, Leases right-of-use In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments,” In January 2017, the FASB issued ASU 2017-01, Business Combinations: Clarifying the Definition of a Business In May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation: Scope of Modification Accounting Recently adopted accounting pronouncements In July 2015, the FASB issued ASU 2015-11, In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation In January 2017, the FASB issued ASU 2017-04, 2017-04

Goodwill Changes in the carrying amount of goodwill were as follows: Year Ended December 31, 2017 2016 Goodwill, January 1 $ 72.1 $ 64.3 Acquisitions (1) 0.1 7.8 Impairments (10.7 ) — Goodwill, December 31 $ 61.5 $ 72.1 (1) Reflects the effects of the TNT acquisition. See Note 19. During the fourth quarter of 2017, we experienced poor performance of our common stock, which led management to believe that a triggering event occurred. As such, an updated goodwill impairment test was performed. The result of the impairment test indicated that the carrying value of goodwill was above the implied fair value. For the purposes of the goodwill impairment test, we estimated the fair value of our sole reporting unit using the market approach. Under the market approach, we utilized the market capitalization of our common stock, and applied an estimated control premium based on an analysis of control premiums paid in acquisitions of companies in the same or similar industries. Because the significant inputs used in this analysis are readily available from public markets or can be derived from observable market transactions, they have been classified as level 2 in the fair value hierarchy. Based on this approach, we determined that the carrying value of our sole reporting unit exceeded the fair value by $10.7 million, which was recorded in “Impairment of goodwill” in the Consolidated Statement of Operations for the year ended December 31, 2017.

Financings Revolving Credit Facility On January 26, 2017, we amended the loan and security agreement with Bank of America to borrow up to $50.0 million on a revolving basis, based upon specified percentages of eligible receivables and inventory, which matures on January 26, 2020 (the “Revolving Credit Facility”). Under the Revolving Credit Facility, the maximum applicable margin for LIBOR rate loans is 2.75%, and the maximum applicable margin for base rate loans is 1.75%. As of December 31, 2017, our Chairman, Chief Executive Officer and President had guaranteed $10.0 million of the borrowings under the Revolving Credit Facility (see Note 17). At December 31, 2017 and 2016, the balance outstanding on the Revolving Credit Facility was $38.6 million and $26.0 million, respectively. Borrowings under the Revolving Credit Facility bear interest at a LIBOR rate or a defined base rate, each plus an applicable margin, depending on the nature of the loan. We are also obligated to pay various fees monthly. At December 31, 2017 and 2016, the weighted average interest rate was 4.59% and 3.95%, respectively. We recorded interest expense of $1.8 million, $0.9 million and $0.7 million for the years ended December 31, 2017, 2016 and 2015, respectively. Under the Revolving Credit Facility, outstanding loans become payable on demand to the extent that such loans exceed the defined Borrowing Base. All obligations under the Revolving Credit Facility are secured by the assets of Revolution, and are guaranteed by Revolution. The Revolving Credit Facility contains covenants that limit our ability to incur other debt, allow a lien on any property, pay dividends, restrict any wholly owned subsidiary from paying dividends, make investments, dispose of property, make loans or advances or enter into transactions with affiliates, among other things. As of December 31, 2017, we were in compliance with our covenants. In connection with obtaining the Revolving Credit Facility, we incurred debt issuance costs, which are being amortized through the maturity date. At December 31, 2017 and 2016, we had $0.6 million and $0.2 million, respectively, of deferred debt issuance costs, which are recorded in “Other assets, net” in the Consolidated Balance Sheets.” Amortization expense of deferred debt issuance costs was $0.3 million, $0.2 million and $0.2 million for the years ended December 31, 2017, 2016 and 2015, respectively.

The note is payable in monthly installments through October 2019 and a lump sum payment of $1.4 million due on November 22, 2018, which may be settled, at our option, in either cash or an equivalent amount of common shares based upon their then-current market value. TNT Acquisition Notes In connection with the acquisition of TNT in May 2016, we issued $2.0 million in promissory notes bearing interest at 5% per annum, of which $1.0 million was due on April 21, 2017 and $1.0 million was due on November 6, 2017. In February 2017, the maturity date was extended to November 6, 2017 for all of the TNT promissory notes. On November 16, 2017, we repaid the TNT acquisition notes, including interest of $0.2 million. We recorded interest expense of less than $0.1 million for both the years ended December 31, 2017 and 2016. Energy Source Acquisition Notes In connection with the acquisition of Energy Source in August 2015, we issued $10.0 million in promissory notes bearing interest at 5% per annum due July 20, 2016, which were supported by an irrevocable letter of credit from RVL. In July 2016, the maturity date was extended to January 20, 2017, with an interest rate of 7%. On January 26, 2017, we repaid the Energy Source acquisition notes, including interest of $0.4 million, using proceeds from the amended Revolving Credit Facility, and the related guarantee provided by RVL was terminated.

Income Taxes

Income Taxes	13. Income Taxes New Tax Legislation On December 22, 2017, the President of the United States signed into law the TCJA. This legislation makes broad and complex changes to the U.S. tax code, including, but not limited to, (i) reducing the U.S. federal statutory tax rate from 35% to 21%; (ii) eliminating the corporate alternative minimum tax (AMT) and changing how existing AMT credits can be realized; (iii) modifying the officer’s compensation limitation, and (iv) changing rules related to uses and limitations of net operating loss carryforwards created in tax years beginning after December 31, 2017. Specifically, the TCJA limits the amount the Company is able to deduct for net operating loss carryforwards generated in taxable years beginning after December 31, 2017 to 80% of taxable income however these net operating loss carryforwards can be carried forward indefinitely. We recognize the effects of changes in tax law, including the TCJA, in the period the law is enacted. Accordingly, the effects of the TCJA have been recognized in the financial statements for the year ended December 31, 2017. Under the Act, our $20.6 million in federal net operating loss carryforwards generated as of December 31, 2017 will continue to be carried forward for 20 years and are expected to be available to fully offset taxable income earned in future tax years. In the quarter ending December 31, 2017, we revalued our deferred tax assets and liabilities due to these changes, including (a) revaluing our federal net deferred tax assets before valuation allowance using the 21% tax rate, resulting in a federal deferred tax provision of $8.8 million; (b) revaluing our federal valuation allowance using the 21% tax rate, including the impact of tax planning strategies, resulting in a federal deferred tax benefit to continuing operations of $(9.2) million; (c) recognizing a federal deferred tax benefit of $(0.7) million for 80% of indefinite lived deferred tax liabilities, which are anticipated to be available as a source of taxable income upon reversal of deferred tax assets that would also have indefinite lives; and (d) recognizing $0.2 million deferred tax benefit due to refundable AMT credits. At December 31, 2017, we have not completed our accounting for the tax effects of the enactment of the TCJA; however in certain cases we have made a reasonable estimate of the effects of the TCJA. Our preliminary estimate of the effects TCJA, including the remeasurement of deferred tax assets and liabilities and the recognition of an income tax benefit related to AMT tax credit carryforwards, is subject to the finalization of management’s analysis related to certain matters, such as developing interpretations of the provisions of the TCJA and the filing of our tax returns. U.S. Treasury regulations, administrative interpretations or court decisions interpreting the TCJA may require further adjustments and changes in our estimates. The final determination of the effects of the TCJA will be completed as additional information becomes available, but no later than one year from the enactment of the TCJA. In all cases, we will continue to make and refine our calculations as additional analysis is completed. In addition, our estimates may also be affected as we gain a more thorough understanding of the tax law. Income Taxes As of December 31, 2017 and December 31, 2016, we reported net operating loss carry forwards for federal income tax purposes of $49.9 million and $21.0 million, respectively, which expire between 2021 and 2037. As of December 31, 2017, we reported net operating loss carry forwards for state income tax purposes of $36.3 million which expire between 2021 and 2037. Utilization of net operating loss carryforwards is dependent on generating future taxable income of the appropriate type and in the appropriate jurisdiction. In addition, as a result of transactions consummated during 2012 and 2013, including the issuance of common and preferred stock and the acquisitions of Seesmart and Relume, substantially all of our net operating loss carryforwards since December 31, 2013 are subject to limitations imposed by Section 382 of the Internal Revenue Code. During 2013, we performed an evaluation of the Section 382 limitations on the use of net operating loss carryforwards and adjusted them accordingly. We have recognized a full valuation allowance related to our remaining net deferred tax assets, including the remaining net operating loss carryforwards. In connection with prior asset acquisitions, including the acquisition of Energy Source, LLC and TNT Energy, LLC, we have recorded a deferred tax liability related to indefinite lived intangibles. In connection with the 2017 tax reform, we released valuation allowance equal to the effect of the deferred tax assets that will create indefinite lived net operating losses and will be available to offset the indefinite lived deferred tax liability. We also released valuation allowance against AMT credits as they have been refundable under the new tax law. Components of deferred tax assets (liabilities) are as follows: December 31, 2017 2016 Accounts receivable $ 2.1 $ 0.5 Inventories 0.6 1.0 Stock options 1.9 2.2 Accrued liabilities 1.0 2.3 Other 0.2 — Net operating loss carryforwards 16.4 9.8 Total deferred tax assets 22.2 15.8 Depreciation (0.2 ) (0.2 ) Intangible assets (3.1 ) (9.0 ) Total deferred tax liabilities (3.3 ) (9.2 ) Valuation allowance (18.9 ) (6.6 ) Net deferred tax liability $ — $ — In accordance with ASC 740, valuation allowances are provided against deferred tax assets if, based on the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. For the year ended December 31, 2017, we recorded a provision for income taxes related to the deferred tax liabilities that was netted against deferred tax assets. For the year ended December 31, 2016, we recorded a provision of $0.1 million, respectively, related to AMT taxes as the deferred tax benefits of the net losses were offset by a corresponding increase in the deferred tax valuation allowance. The following is a reconciliation of tax computed at the statutory federal rate to the income tax expense in the statements of operations for the years ended December 31, 2017, 2016, and 2015: December 31, 2017 2016 2015 Amount % Amount % Amount % Tax benefit at statutory federal rate $ (18.1 ) (34.0 ) $ (0.3 ) (34.0 ) $ (0.8 ) (34.0 ) Change in valuation allowance 7.5 14.1 1.5 178.8 0.4 16.2 Change in income tax rate to 21% 8.8 16.6 — — — — Non-deductible 2.3 4.3 0.5 57.0 1.1 45.0 Adjustment to net operating loss carryforwards — — — — (0.5 ) (21.1 ) Other adjustments (0.5 ) (0.2 ) (1.7 ) (201.8 ) (0.2 ) (6.1 ) Income tax benefit $ — 0.8 $ — — $ — —

See Note 9. Aston Capital, LLC On April 1, 2016, we entered into a $2.6 million amended and restated promissory note with Aston Capital, LLC (“Aston”), which bears interest at 9% annually and matures on April 1, 2019, which can be prepaid at our option. In May 2017, we amended the promissory note with Aston to include an additional $9.1 million of borrowings. In March 2017, Aston provided a $1.5 million advance that bears interest annually at 9%, which is included in “Related party notes payable” in the Consolidated Balance Sheets at December 31, 2017. During 2017, we repaid $0.5 million of the advance. On November 30, 2016, Aston provided a $1.5 million advance that bore interest annually at 9%, which is included in “Related party notes payable” in the Consolidated Balance Sheets at December 31, 2016, and was repaid on January 26, 2017 using proceeds from the amended Revolving Credit Facility.

On May 12, 2016, we granted 250,000 shares of restricted stock to Aston, which vest in three annual installments on May 12, 2017, 2018, and 2019. The Audit Committee of the Board will consider from time to time (at a minimum at such times when the Compensation Committee of the Board evaluates director compensation) whether additional compensation to Aston is appropriate given the nature of the services provided. Our corporate headquarters utilizes space in Stamford, Connecticut, which is also occupied by affiliates of our Chairman and Chief Executive Officer.

We depend on these manufacturers to satisfy performance and quality specifications and to dedicate sufficient production capacity for finished products within scheduled delivery times. Accordingly, the loss of one or more of these manufacturers or delays in obtaining shipments could have a material adverse effect on our operations until such time as an alternative manufacturer could be found.

Acquisition of TNT Energy, LLC	19. Acquisition of TNT Energy, LLC In May 2016, we completed the acquisition of TNT, a turnkey provider of LED lighting-based energy savings projects within the commercial, industrial, hospitality, retail, education and municipal sectors. TNT’s headquarters is located in Raynham, Massachusetts. The acquisition of TNT is expected to expand our footprint within key lighting retrofit markets in the United States. We believe this is a direct complementary fit with our division, Energy Source, based in Providence, RI. In addition to its broad existing customer base, TNT is a contract vendor for the Small C&I Business Programs of northeast utility companies, with a defined territory of approximately 120 municipalities throughout Massachusetts. We acquired TNT for its management team, its client base and operational and business development synergies. We accounted for the acquisition of TNT under ASC 805, Business Combinations Consideration: Cash paid $ 8.6 Promissory note 2.0 Contingent consideration 4.1 Net Assets $ 14.7 Fair Value of Assets Acquired and Liabilities Assumed: Working capital, net $ 0.9 Goodwill (1) 7.9 Intangible assets 5.9 Net Assets $ 14.7 (1) Since our initial valuation on the date of the acquisition, we recorded a $1.7 million increase to goodwill related to adjustments in working capital, including $0.1 million in the second quarter of 2017. Goodwill is expected to be deductible for income tax purposes.

Restructuring Activities	20. Restructuring Activities In the fourth quarter of 2017, we announced a restructuring plan to further streamline our operations, eliminate redundancies at certain divisions and address certain operational functions. As part of the restructuring, we (i) consolidated the operations of three divisions into one, (ii) consolidated sales, purchasing, bidding and proposal and accounting functions, (iii) expanded and refocused our marketing resources, including changes to key management positions at certain divisions, and (iv) exited certain product lines and related operations, including the eliminations of a number of warehouse locations. In connection with this restructuring, we abandoned certain assets, including inventory of $9.2 million and certain discontinued customer accounts and other, totaling $15.0 million (net of expected recoveries), of which $9.2 million was recorded as part of “Cost of sales” in the Consolidated Statements of Operations. In addition, we recorded $1.9 million of accrued restructuring costs related to severance, outplacement and other employee costs, lease terminations and other relocation costs. Restructuring charges have been recorded in accordance with ASC 420-10, Exit or Disposal Cost Obligations one-time 420-10, 420-10, The actions taken for this restructuring will be substantially completed by the end of the first quarter of 2018.

Quarterly Results of Operations (Unaudited)	21. Quarterly Results of Operations (Unaudited) The following represents our unaudited quarterly results for the years ended December 31, 2017 and 2016. These quarterly results were prepared in conformity with GAAP and reflect all adjustments that are, in the opinion of management, fair and necessary for a fair statement of results, and were of a normal recurring nature. The 2017 and 2016 acquisitions are included in the quarterly consolidated results of operations from their respectively acquisition dates.

The Company (Policies)

The Company (Policies)	12 Months Ended
	Dec. 31, 2017
Basis of presentation	Basis of presentation The consolidated financial statements included in this Form 10-K
Use of estimates	Use of estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The most significant estimates relate to valuation of receivables and inventories, purchase price allocation of acquired businesses, impairment of goodwill and long-lived assets, income taxes, and contingencies. It is at least reasonably possible that the effect on the financial statements of a change in estimate due to one or more future confirming events could have a material effect on the financial statements.
Stock Split	Stock Split On March 10, 2016, we filed a certificate of amendment to our Amended and Restated Certificate of Incorporation, as amended, to effect a 1-for-10
Liquidity and Capital Resources	Liquidity and Capital Resources On January 26, 2017, we amended the Revolving Credit Facility which enabled us to borrow up to $50.0 million on a revolving basis, based upon specified percentages of eligible receivables and inventory, which matures on January 26, 2020. See Note 9. Our liquidity as of December 31, 2017 and 2016 was $7.4 million and $1.9 million, respectively, which consisted of cash and cash equivalents of $0.9 million and $0.9 million, respectively, and additional borrowing capacity under the Revolving Credit Facility of $6.5 million and $1.0 million, respectively. Historically, our significant shareholder, RVL 1 LLC (“RVL”), and its affiliates have been a significant source of financing, and they continue to support our operations. See Note 17. At December 31, 2017 and 2016, we had working capital of $34.3 million and $51.3 million, respectively. We believe we have adequate resources to meet our cash requirements for the foreseeable future.
Fair Value Measurements	Fair Value Measurement We measure fair value on a recurring basis utilizing valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs, to the extent possible, and consider counterparty credit risk in our assessment of fair value. The fair value hierarchy is as follows: Level 1 – Quoted prices in active markets for identical assets and liabilities; Level 2 – Quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active or other inputs that are observable or can be corroborated by observable market data; and Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. Cash and cash equivalents, trade and unbilled contract receivables, inventories, other current assets, accounts payable, and accrued and other liabilities are classified as Level 1 as their carrying values approximate fair value since they are short term in nature and they are receivable or payable on demand. Based on the borrowing rates currently available for bank loans with similar terms and average maturities, the fair value of notes payable are equal to the carrying value. As such, notes payable are classified as Level 1. See Notes 9 and 17. The estimated fair value of the reporting unit in our goodwill impairment assessment utilized the market approach based on inputs that are readily available from public markets or can be derived from observable market transactions, and have been classified as level 2 in the fair value hierarchy. The fair values of intangible assets in our long-lived asset impairment assessment were established based on projected discounted cash flows, which were based on significant unobservable inputs and have been classified as Level 3 in the fair value hierarchy. The estimated fair value of assets and liabilities acquired in business combinations utilize inputs classified as Level 3 in the fair value hierarchy.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all investments with an original maturity of three months or less to be cash equivalents. We maintain cash and cash equivalents in bank accounts that may exceed federally insured limits. The financial institutions where our cash and cash equivalents are held are highly rated. We have not experienced any losses in such accounts, and believe we are not exposed to significant credit risk.
Accounts Receivable	Accounts Receivable Accounts receivable are customer obligations due under normal trade terms. We perform periodic credit evaluations of our customers’ financial condition. We record an allowance for doubtful accounts based upon factors surrounding the credit risk of certain customers, and specifically identified amounts that we believe to be uncollectible. Recovery of bad debt amounts previously written off is recorded as a reduction of bad debt expense in the period the payment is collected. If our actual collection experience changes, revisions to our allowance may be required. After all attempts to collect a receivable have failed, the receivable is written off against the allowance. See Note 3.
Inventories	Inventories Inventories are stated at the lower of cost (first-in, first-out)
Property and Equipment	Property and Equipment Property and equipment, net is stated at cost (or fair value, if acquired as part of a business combination) less accumulated depreciation, and is depreciated over its estimated useful life using the straight-line method as follows: Machinery and equipment 3-7 Furniture and fixtures 5-7 Computers and software 3-7 Motor vehicles 5 years Leasehold improvement Lesser of lease term or estimated useful life Maintenance and repairs are expensed as incurred. Upon retirement or sale, the cost and related accumulated depreciation are removed from the respective account, and any resulting gain or loss is recognized in the Consolidated Statements of Operations. See Note 5.
Goodwill	Goodwill Goodwill is not amortized, but is subject to annual impairment testing unless circumstances dictate more frequent assessments. We perform an annual impairment assessment for goodwill during the fourth quarter of each year or more frequently whenever changes in circumstances indicate that the fair value of the asset may be less than the carrying amount. We have one reporting unit for goodwill impairment testing purposes. In testing goodwill for impairment, we compare the fair value of the reporting unit to its carrying amount. The fair value of the reporting unit is determined by calculating our market capitalization at the impairment test day. If the fair value of the reporting unit is greater than its carrying amount, there is no impairment. If the carrying amount of goodwill exceeds the implied fair value of goodwill, an impairment loss is recognized in an amount equal to the excess. On October 1, 2017, we performed our annual goodwill impairment test and the estimated fair value exceeded carrying value. We concluded that goodwill, as of October 1, 2017, was not impaired . During the fourth quarter of 2017, we experienced poor performance of our stock price, which led management to believe that a triggering event occurred. As such, an updated goodwill impairment test was performed. Because we elected to early adopt Accounting Standards Update (“ASU”) 2017-04, Simplifying the Test for Goodwill Impairment
Intangible Assets	Intangible Assets Intangible assets, net is stated at cost or fair value, if acquired as part of a business combination, less accumulated amortization, and is amortized over its estimated useful life using the straight-line method as follows: Customer relationships 10-15 Trademarks and trade names 12-17 Non-compete 6 years Favorable leases 10 years We evaluate the recoverability of the carrying value of long-lived assets whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The long-lived asset is grouped with other assets at the lowest level for which identifiable cash flows are largely independent of the cash flows of other groups of assets and liabilities. We assess whether the projected undiscounted cash flows of our long-lived assets are sufficient to recover the carrying amount of the asset group being assessed. If the undiscounted projected cash flows are less than the carrying value of the assets, we calculate an impairment by comparing the carrying value of the asset group to its fair value. The amount of the impairment of long-lived assets is written off against earnings in the period in which the impairment is determined. During the fourth quarter of 2017, management performed an impairment test on certain long-lived asset groups. The result of the impairment test indicated that certain intangible assets were impaired by $10.5 million. See Note 7.
Purchase Price Obligations	Purchase Price Obligations In connection with certain prior acquisitions, we are obligated to issue contingent consideration. We determine the fair value of certain purchase price obligations on a recurring basis based on a probability-weighted discounted cash flow analysis and Monte Carlo simulation. The fair value remeasurement is based on significant inputs not observable in the market and thus represents a Level 3 measurement. On a quarterly basis, we reassess our current estimates of performance relative to the stated targets and adjust the liability to fair value. Any such adjustments are included in “Acquisition, severance and transition costs” in the Consolidated Statements of Operations. See Note 10.
Contingencies	Contingencies In accordance with Accounting Standards Codification (“ASC”) 450, Contingencies
Revenue Recognition	Revenue Recognition We recognize revenue from our product sales upon shipment or delivery to customers in accordance with the respective contractual arrangements, provided no significant obligations remain and collection is probable. For sales that include customer acceptance terms, revenue is recorded after customer acceptance at the applicable location. It is our policy that all sales are final. Requests for returns are reviewed on a case by case basis. As revenue is recorded, we accrue an estimated amount for product returns as a reduction of revenue. We recognize revenue from fixed-price and modified fixed-price contracts for turnkey energy conservation projects using the percentage-of-completion percentage-of-completion
Warranties and product liability	Warranties and product liability Our products typically carry a warranty that ranges from one to ten years and includes replacement of defective parts. A warranty reserve is recorded for the estimated costs associated with warranty expense related to recorded sales, which is included within accrued liabilities. We recorded warranty expense of $0.2 million for each of the years ended December 31, 2017, 2016 and 2015, which was included in “Selling, general and administrative” in the Consolidated Statements of Operations. At both December 31, 2017 and 2016, we had recorded a warranty and product liability of $0.4 million in the Consolidated Balance Sheets.
Sales Tax Revenue	Sales Tax Revenue We record sales tax revenue on a gross basis (included in both “Revenues” and “Cost of sales” in the Consolidated Statements of Operations). For the years ended December 31, 2017, 2016 and 2015, revenues from sales taxes were $4.1 million, $5.2 million and $4.5 million, respectively.
Shipping and Handling	Shipping and Handling Shipping and handling costs related to the acquisition of goods from vendors are included in cost of sales.
Research and Development	Research and Development Research and development costs to develop new products, which consist of salaries, contractor fees, building cost, utilities, administrative expenses and allocations of corporate costs, are charged to expense as incurred.
Advertising Expense	Advertising Expense Advertising costs, included in “Other selling, general and administrative” on the Consolidated Statements of Operations are expensed when the advertising first takes place. We promote our product lines through print media and trade shows, including trade publications and promotional brochures. Advertising expense was $0.3 million, $0.2 million and $0.3 million for the years ended December 31, 2017, 2016 and 2015, respectively.
Income taxes	Income taxes Income taxes are provided for the tax effects of transactions reported in the financial statements and consist of taxes currently due plus deferred taxes resulting from temporary differences. Such temporary differences result from differences in the carrying value of assets and liabilities for tax and financial reporting purposes. The deferred tax assets and liabilities represent the future tax consequences of those differences, which will either be taxable or deductible when the assets and liabilities are recovered or settled. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. We applied the provisions of ASC 740, Income Taxes We evaluate the adequacy of the valuation allowance quarterly and, if our assessment of whether it is more likely than not that the related tax benefits will be realized changes, the valuation allowance will be increased or reduced with a corresponding benefit or charge included in income. In December 2017, the U.S., enacted the Tax Cuts and Jobs Act (“TCJA”), which made significant changes to U.S. federal income tax law. Shortly after enactment of the TCJA, the United States Securities and Exchange Commission’s (the “SEC”) staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), which provides guidance on accounting for the impact of the TCJA. Under SAB 118, an entity would use a similar approach as the measurement period provided in the Business Combinations Topic of the ASC. An entity will recognize those matters for which the accounting can be completed. For matters that have not been completed, the entity would either (1) recognize provisional amounts to the extent that they are reasonably estimable and adjust them over time as more information becomes available or (2) for any specific income tax effects of the TCJA for which a reasonable estimate cannot be determined, continue to apply the Income Taxes Topic of the ASC on the basis of the provisions of the tax laws that were in effect immediately before the TCJA was signed into law. We have prepared our consolidated financial statements for the fiscal year ended December 31, 2017 in accordance with the Income Taxes Topic of the ASC as allowed by SAB 118. See Note 13.
Loss per Share	Loss per Share Basic loss per share is computed by dividing net loss attributable to common stockholders by the weighted average common shares outstanding for the period. Diluted loss per share is computed giving effect to all potentially dilutive common shares. Potentially dilutive common shares consist of incremental shares issuable upon the exercise of stock options and vesting of restricted shares and the conversion of outstanding convertible securities. In periods in which a net loss has been incurred, all potentially dilutive common shares are considered anti-dilutive and thus are excluded from the calculation. See Note 14.
Stock-Based Compensation	Stock-Based Compensation Restricted Stock and Restricted Stock Unit Awards (Equity) Restricted Stock Awards (Liability) non-employee Equity-Based Payments to Non-Employees re-measured Option Awards
Business Acquisitions	Business Acquisitions Business acquisitions are accounted for using the acquisition method of accounting, which requires recording assets acquired and liabilities assumed at fair value of the acquisition date. Under the acquisition method of accounting, each tangible and separately identifiable intangible asset acquired and liability assumed is recorded based on their preliminary estimated fair values on the acquisition date. Acquisition related costs are expensed as incurred, and are included in “Acquisition, severance and transition costs” in the Consolidated Statements of Operations. See Note 19.
Recent accounting pronouncements	Recent accounting pronouncements not yet adopted In May 2014, the Financial Accounting Standards Board (the “FASB”) issued ASU 2014-09, Revenue from Contracts with Customers 2014-09, We have identified that the main types of contracts that require evaluation as to what, if any, changes will be necessary under ASC 606 as compared to legacy accounting guidance are (a) product sales that are shipped to customers from either our warehouses or directly from our vendors and (b) contracts that involve a combination of product and installation services. We have evaluated the provisions of ASC 606 against our existing accounting policies and practices, including reviewing standard purchase orders, invoices, shipping terms, and agreements with customers to determine the impact, if any, on the timing, measurement and presentation of revenue recognition and the cost of sales. The review considered, among other matters, the evaluation and identification of distinct performance obligations and the measurement of our progress toward satisfying identified performance obligations. We determined that the adoption of ASC 606 will not impact the timing of our billings to customers or the receipt of customer payments. Under ASC 606, incremental contract costs, which includes sales commissions, are required to be capitalized as contract assets and amortized over the period these costs are expected to be recovered. Although we incur such costs, our contracts are typically completed within one year. As such, we have elected the practical expedient provided in ASC 606 and expense incremental contract costs when incurred. We have evaluated this standard and determined that the adoption of ASC 606 will not have a material effect on our financial statements. We have evaluated our processes and controls necessary for implementing this standard, including the increased disclosure requirements. In February 2016, the FASB issued ASU 2016-02, Leases right-of-use In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments,” In January 2017, the FASB issued ASU 2017-01, Business Combinations: Clarifying the Definition of a Business In May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation: Scope of Modification Accounting Recently adopted accounting pronouncements In July 2015, the FASB issued ASU 2015-11, In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation In January 2017, the FASB issued ASU 2017-04, 2017-04
