Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(2) Summary of Significant Accounting Policies Principles of Consolidation The accompanying consolidated financial statements include the accounts of AETI and its wholly-owned subsidiaries, M&I and M&I Brazil, and the assets of SCES through the disposition date in June 2016. Significant intercompany accounts and transactions are eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting period. Actual results could differ from those estimates. The most significant estimates made by management include: (1) Percentage-of-completion estimates on long-term contracts (2) Estimates of the provision for doubtful accounts (3) Estimated useful lives of property and equipment (4) Valuation allowances related to deferred tax assets As future events and their effects cannot be determined with absolute certainty, actual results may differ from the estimates used in preparing the accompanying consolidated financial statements. Significant estimates and assumptions are required as part of determining inventory and accounts receivable valuation, estimating depreciation, amortization and recoverability of long-lived assets, establishing self-insurance, warranty, legal and other reserves, performing intangible impairment analyses, and in establishing valuation allowances on deferred income tax assets and reserves for tax examination exposures. Financial Instruments The Company includes fair value information in the notes to the consolidated financial statements when the fair value of its financial instruments is different from the book value. When the book value approximates fair value, no additional disclosure is made, which is the case for financial instruments outstanding as of December 31, 2017 and 2016. The Company assumes the book value of those financial instruments that are classified as current approximates fair value because of the short maturity of these instruments. For non-current financial instruments, the Company uses quoted market prices or, to the extent that there are no available quoted market prices, market prices for similar instruments. Cash and Cash Equivalents Cash equivalents consist of liquid investments with original maturities of three months or less. Cash balances routinely exceed FDIC limits however all cash is maintained in JP Morgan Chase and Frost Bank and believed to be secure. Short-term investments Short-term investments consist of any fund held in certificate of deposit with original maturities greater than three months and investments in debt and equity securities with maturity of one year or less. Accounts Receivable and Allowance for Bad Debts The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The estimate is based on management’s assessment of the collectability of specific customer accounts and includes consideration for credit worthiness and financial condition of those specific customers. The Company also reviews historical experience with the customer, the general economic environment and the aging of its receivables. The Company records an allowance to reduce receivables to the amount it reasonably believes to be collectible. Based on this assessment, management believes the allowance for doubtful accounts is adequate. The bad debt expense was a net recovery of ($0.13) million and expense of $0.21 million for the fiscal years ended December 31, 2017 and 2016. Inventories Inventories are stated at the lower of cost or market, with material value determined using an average cost method. Inventory costs for work-in-process include direct material, direct labor, production overhead and outside services. Indirect overhead is apportioned to work-in-process based on direct labor incurred. Property, Plant and Equipment Property, plant and equipment are stated at cost. Expenditures for repairs and maintenance are expensed as incurred while renewals and betterments are capitalized. Depreciation is calculated on the straight-line basis over the estimated useful lives of the assets after giving effect to salvage values. Long-lived assets If events or circumstances indicate the carrying amount of an asset may not be recoverable, including intangible assets, management tests long-lived assets for impairment. If the estimated future cash flows are projected to be less than the carrying amount, an impairment write-down (representing the carrying amount of the long-lived asset which exceeds the present value of estimated expected future cash flows) would be recorded as a period expense. Events that would trigger an impairment test include the following: • A significant decrease in the market price of a long-lived asset. • A significant change in the use of long-lived assets or in its physical condition. • A significant change in the business climate that could affect an assets value. • An accumulation of cost significantly greater than the amount originally expected to acquire or construct a long-lived asset. • A current period operating or cash flow loss combined with a history of such losses or a forecast demonstrating continued losses associated with the use of a long-lived asset. • An expectation to sell or otherwise dispose of a long-lived asset significantly before the end of its estimated useful life. Based on management’s reviews during each of the years ended December 31, 2017 and 2016, there were no events or circumstances that caused management to believe that impairments were necessary. Intangible Assets Intangible Assets at December 31, 2017 Useful Cost Accumulated Net Value (in thousands) Intellectual property 3 $ 322 $ 322 $ - License 5 358 118 240 License - 218 - 218 $ 898 $ 440 $ 458 During 2014 we acquired arc-resistant technology and capitalized the cost of $0.22 million. During 2016, the Company capitalized cost of $0.36 million for the testing associated with certifications for IntelliSafe™ products. The cost is being amortized over its useful life of 5 years. Amortization expense of $0.07 million and $0.05 million was recognized during the year ended December 31, 2017 and 2016, respectively, and is included in the cost of sales in the consolidated statements of operations. Income Taxes The Company uses the asset and liability method to account for income taxes. Under this method of accounting for income taxes, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using the enacted tax rates and laws that will be in effect when the differences are expected to be reported to the taxing authority. The Company also records any financial statement recognition and disclosure requirements for uncertain tax positions taken or expected to be taken in its tax return. Financial statement recognition of the tax position is dependent on an assessment of a 50% or greater likelihood that the tax position will be sustained upon examination, based on the technical merits of the position. Any interest and penalties related to uncertain tax positions are recorded as interest expense in the accompanying consolidated statements of operations. Foreign Currency Gains and Losses Foreign currency translations are included as a separate component of comprehensive income. The Company has determined the local currency of its foreign subsidiary and foreign joint ventures to be the functional currency. In accordance with ASC 830, the assets and liabilities of the foreign equity investees and foreign subsidiary, denominated in foreign currency, are translated into United States dollars at exchange rates in effect at the consolidated balance sheet date and net sales and expenses are translated at the average exchange rate for the period. Related translation adjustments are reported as comprehensive income, net of deferred income taxes, which is a separate component of stockholders’ equity, whereas gains and losses resulting from foreign currency transactions are included in results of operations. Net Sales Recognition The Company reports earnings from fixed-price and modified fixed-price long-term contracts on the percentage-of-completion method. Earnings are accrued based on the ratio of costs incurred to total estimated costs. However, for our manufacturing activities, we have determined that labor incurred provides an improved measure of percentage-of-completion. Costs include direct material, direct labor, and job related overhead. Losses expected to be incurred on contracts are charged to operations in the period such losses are determined. A contract is considered complete when all costs except insignificant items have been incurred and the facility has been accepted by the customer. Net sales from non-time and material jobs of a short-term nature (typically less than one month) are recognized on the completed-contract method after considering the attributes of such contracts. This method is used because these contracts are typically completed in a short period of time and the financial position and results of operations do not vary materially from those which would result from use of the percentage-of-completion method. The Company records net sales from its time and material projects on a completed service basis after customer acknowledgement that the service has been completed and accepted. In addition, the Company sells certain purchased parts and products. These net sales are recorded when the product is shipped and title passes to the customer. The asset, “Work-in-process,” which is included in inventories, represents the cost of labor, material, and overhead in excess of amounts billed on jobs accounted for under the completed-contract method. For contracts accounted for under the percentage-of-completion method, the asset, “Costs and estimated earnings in excess of billing on uncompleted contracts,” represents net sales recognized in excess of amounts billed and the liability, “Billings in excess of costs and estimated earnings on uncompleted contracts,” represents billings in excess of net sales recognized. Any billed net sale that has not been collected is reported as accounts receivable. The timing of when we bill our customers is generally dependent upon advance billing terms or completion of certain phases of the work. On occasion, the Company enters into long-term contracts that include both a service component and a manufacturing component. For segmented contracts, the Company recognizes net sales as if they were separate contracts over the performance periods of the individual elements. Contract net sales recognition inherently involves estimation, including the contemplated level of effort to accomplish the tasks under the contract, the cost of the effort, and an ongoing assessment of progress toward completing the contract. From time to time, as part of the normal management processes, facts develop that requires revisions to estimated total cost or net sales expected. The cumulative impact of any revisions to estimates and the full impact of anticipated losses on contracts are recognized in the period in which they become known. Shipping and Handling Fees and Costs Shipping and handling fees, if billed to customers, are included in net sales. Shipping and handling costs associated with inbound freight are expensed as incurred. Shipping and handling costs associated with outbound freight are classified as cost of sales. Uses and Sources of Liquidity The Company’s primary need for liquidity is to fund working capital requirements of the Company’s businesses, capital expenditures and for general corporate purposes, including debt repayment. The Company has incurred losses and experienced negative operating cash flows for the past several years, and accordingly, the Company has taken a number of actions to continue to support its operations and meet its obligations. During 2016, the Company undertook actions to monetize the value of certain of its assets which included disposition of the manufacturing facility and related assets in Bay St. Louis Mississippi. During 2017, the Company refinanced its outstanding loans which at that time provided approximately $1.0 million of working capital. In addition, the Board of Directors of the Company created a special committee to address strategic initiatives that include addressing liquidity. The Company continues to face a challenging competitive environment and while it continues to focus on its overall profitability, including managing expenses, it reported a loss in 2017 and was required to fund cash used in operating activities with cash from investing and financing activities. Going forward, the Company expects to generate additional liquidity from strategic initiatives including monetization of assets and additional debt and equity financing actions. The Company expects that these actions will be executed in alignment with the anticipated timing of its liquidity needs. The Company also continues to explore ways to unlock value across a range of assets, including exploring ways to maximize the value of its manufacturing facility in Beaumont, Texas. The Company expects to continue to optimize both international and domestic operations including expansion of its service business in Brazil and diversification of its joint venture operations in China. The Company’s historical operating results indicate substantial doubt exists related to its ability to continue as a going concern. However, the Company believes it is probable that the actions discussed above will occur and mitigate the substantial doubt raised by its historical operating results and satisfy its estimated liquidity needs 12 months from the issuance of the financial statements. However, the Company cannot predict, with certainty, the outcome of its actions to generate liquidity, including the availability of additional debt financing, or whether such actions would generate the expected liquidity as currently planned. In addition, the current Senior Secured Note and Redeemable Preferred Stock both contain certain limitations on our ability to sell assets, which could impact its ability to complete asset sale transactions or its ability to use proceeds from those transactions to fund our operations. Therefore, any planned actions must take into account the ability to transact within any applicable restrictions under these agreements. If the Company continues to experience operating losses, and is not able to generate additional liquidity through the mechanisms described above or through some combination of other actions, while not expected, it may not be able to access additional liquidity and we might need to secure additional sources of funds, which may or may not be available to us. Additionally, a failure to generate additional liquidity could negatively impact the Company’s access to materials or services that are important to the operation of its business. Concentration of Market Risk and Geographic Operations Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of trade accounts receivable. The Company’s market risk is dependent primarily on the strength of the oil and gas and energy related industries. The Company grants credit to customers and generally does not require security except in the case of certain international contracts. Procedures are in effect to monitor the credit worthiness of its customers. The Company sells its products and services in domestic and international markets; however, significant portions of the Company’s sales are concentrated with customers located in the Gulf Coast region of the United States. The Gulf Coast region accounts for approximately 8% and 47% of the Company’s net sales during the years ended December 31, 2017 and 2016, respectively. Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers, which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU No. 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU No. 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required under existing U.S. GAAP. The standard is effective for annual periods beginning after December 15, 2016, and interim periods therein, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU No. 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). In July 2015, the FASB issued ASU No. 2015-14 which delayed the effective date of ASU No. 2014-09 by one year (effective for annual periods beginning after December 15, 2017). The Company adopted ASU 2014-09, effective January 1, 2018, using the modified retrospective method. The adoption of the standard will not have a material impact on the Company’s revenue recognition policies, other than enhanced disclosures related to the disaggregation of revenues from contracts with customers, the Company’s performance obligations and any significant judgments. In August 2014, the FASB issued an accounting standards update which requires management to assess whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the financial statements are issued. If substantial doubt exists, additional disclosures are required. This update was effective for the Company's annual period ended December 31, 2016. The Company's assessment of our ability to continue as a going concern is further discussed in the "Uses and Sources of Liquidity" paragraph above. The adoption of the new standard did not have a material impact on the Company’s consolidated financial position, results of operations, cash flows or disclosures. In July 2015, the FASB issued ASU No. 2015-11. Inventory (Topic 330): Simplifying the Measurement of Inventory, which is intended to converge U.S. GAAP on this topic with International Financial Reporting Standards (“IFRS”). ASU No. 2015-11 focuses on the premeasurement of inventory measured using any method other than LIFO, for example, average cost. Inventory within the scope of ASU No. 2015-11 is required to be measured at the lower of cost and net realizable value. When evidence exists that the net realizable value of inventory is lower than its cost, the difference shall be recognized as a loss in earnings in the period in which it occurs. That loss may be required, for example, due to damage, physical deterioration, obsolescence, changes in price levels, or other causes. For public business entities, the amendments in ASU No. 2015-11 are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The adoption of ASU No. 2015-11 did not have a significant impact on the Company’s consolidated financial position, results of operations and disclosures. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. ASU No. 2016-01 requires (1) an entity to measure equity instruments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) at fair value with changes in fair value recognized in net income; (2) entities to use the exit price notation when measuring the fair value of financial instruments for disclosure purposes; (3) separate presentation of financial assets and financial liabilities by measurement category and form of financial asset; and (4) elimination of the requirement to disclose the methods and significant assumptions used to estimate fair value that is required to be disclosed for financial instruments measured at amortized cost. ASU No. 2016-01 is effective for fiscal years beginning after December 15, 2017 with early adoption permitted. Management is currently evaluating the future impact of ASU No. 2016-01 on the Company’s consolidated financial position, results of operations and disclosures. In February 2016, the FASB issued ASU No. 2016-02, Leases, which requires lessees to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under ASU No. 2016-02, lessor accounting is largely unchanged. ASU No. 2016-02 is effective for fiscal years beginning after December 15, 2018 with early application permitted. Lessees and lessors must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases expiring before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. Management is currently reviewing the Company’s various leases to identify those affected by ASU No. 2016-02. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, to clarify two aspects of Topic 606: (i) identifying performance obligations; and (ii) the licensing implementation guidance. The amendments do not change the core principle of the guidance in Topic 606. The effective date and transition requirements for ASU No. 2016-10 are the same as the effective date and transition requirements for ASU No. 2014-09. This standard was adopted effective January 1, 2018, see ASU No. 2014-09 above for additional information. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients. ASU No. 2016-12 provides narrow-scope improvements to the guidance on collectability, noncash consideration, and completed contracts at transition. The amendment also provides a practical expedient for contract modifications at transition and an accounting policy election related to the presentation of sales taxes and other similar taxes collected from customers and are expected to reduce the judgment necessary to comply with Topic 606. The effective date and transition requirements for ASU No. 2016-12 are the same as the effective date and transition requirements for ASU No. 2014-09. This standard was adopted effective January 1, 2018, see ASU No. 2014-09 above for additional information. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU No. 2016-13 eliminates the probable initial recognition threshold in current U.S. GAAP and, instead, requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. In addition, ASU No. 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. ASU No. 2016-13 is effective for annual periods beginning after December 15, 2019, with early application permitted in annual periods beginning after December 15, 2018. The amendments of ASU No. 2016-13 should be applied through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. Management is currently evaluating the future impact of ASU No. 2016-13 on the Company’s consolidated financial position, results of operations and disclosures. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. ASU No. 2016-15 addresses eight specific cash flow issues and is intended to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. ASU No. 2016-15 is effective for reporting periods beginning after December 15, 2017. Early adoption is permitted. Management does not expect the adoption of ASU No. 2016-15 to have a significant impact on the Company’s consolidated financial position, results of operations and disclosures because it only affects presentation of specific items within the cash flow statement. In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers. ASU No. 2016-20 allows entities not to make quantitative disclosures about remaining performance obligations in certain cases and require entities that use any of the new or previously existing optional exemptions to expand their qualitative disclosures. The amendment also clarifies narrow aspects of ASC 606, including contract modifications, contract costs, and the balance sheet classification of items as contract assets versus receivables, or corrects unintended application of the guidance. The effective date and transition requirements for ASU No. 2016-20 are the same as the effective date and transition requirements for ASU No. 2014-09. Management is currently evaluating the future impact of ASU No. 2016-20 on the Company’s consolidated financial position, results of operations and disclosures. Please refer to ASU No. 2014-09 above. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. ASU No. 2017-01 clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of a business or as acquisitions (or disposals) of assets. ASU No. 2017-01 is effective for annual periods beginning after December 15, 2018, with early adoption permitted under certain circumstances. The amendments of ASU No. 2017-01 should be applied prospectively as of the beginning of the period of adoption. Management is currently evaluating the future impact of ASU No. 2017-01 on the Company’s consolidated financial position, results of operations and disclosures. In January 2017, the FASB issued ASU No. 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments – Equity Method and Joint Ventures (Topic 323): Amendments to SEC Paragraphs Pursuant to Staff Announcements at the September 22, 2016 and November 17, 2016 EITF Meetings. The amendments in this update relate to disclosures of the impact of recently issued accounting standards. The SEC staff’s view that a registrant should evaluate ASC updates that have not yet been adopted to determine the appropriate financial disclosures about the potential material effects of the updates on the financial statements when adopted. If a registrant does not know or cannot reasonably estimate the impact of an update, then in addition to making a statement to that effect, the registrant should consider additional qualitative financial statement disclosures to assist the reader in assessing the significance of the impact. The staff expects the additional qualitative disclosures to include a description of the effect of the accounting policies expected to be applied compared to current accounting policies. Also, the registrant should describe the status of its process to implement the new standards and the significant implementation matters yet to be addressed. The amendments specifically addressed recent ASC amendments to ASU No. 2016-13, Financial Instruments – Credit Losses, ASU No. 2016-02, Leases, and ASU No. 2014-09, Revenue from Contracts with Customers, although, the amendments apply to any subsequent amendments to guidance in the ASC. ASU No. 2017-03 is effective upon issuance and did not have a significant impact on the Company’s consolidated financial position, results of operations and disclosures.

Equity Method Investments And Joint Ventures [Abstract]
Advances to and Investments in Foreign Joint Ventures' Operations	(6) Advances to and Investments in Foreign Joint Ventures’ Operations The Company has a foreign joint venture agreement and holds a 40% interest in a Chinese company, BOMAY, which builds electrical systems for sale in China. The majority partner in this foreign joint venture is a subsidiary of a major Chinese oil company. M&I made an initial investment of $1.00 million in 2006 and made an additional $1.00 million investment in 2007. The Company’s equity income from the foreign joint venture was $0.43 million and $0.80 million for the years ended December 31, 2017 and 2016, respectively. During the years ended December 31, 2017 and 2016, the Company received $0.78 million and $0.59 million, respectively, in dividends from BOMAY. Sales made to the foreign joint venture were $0.00 million and $0.11 million for the years ended December 31, 2017 and 2016, respectively. Accounts receivable from BOMAY were $0.00 million and $0.04 million at December 31, 2017 and 2016. The Company owns a 41% interest in MIEFE which provides additional sales and technical support in Asia. The equity income for the Company’s interest in the two joint ventures for 2017 and 2016 was: BOMAY $0.43 million vs. $0.80 million and MIEFE $0.22 million vs. ($0.27) million. During 2016, the Company’s share of cumulative losses from MIEFE exceeded the Company’s initial investment balance. The Company applied the losses to the investment balance to the extent of the initial investment amount, with the remaining losses in the amount of $0.27 million accrued for in accounts payable and other liabilities to reflect management’s intention to fund the losses. In November 2017, the Company executed a letter of intent to divest of its ownership interest in MIEFE. As a result, the Company reversed $0.22 million of the accrued losses. During 2017 and 2016, the Company also recognized approximately $0.25 million for each year, for employee related expenses directly attributable to the foreign joint ventures. Sales to foreign joint ventures’ operations are made on an arm’s length basis and intercompany profits, if any, are eliminated in consolidation. Summary financial information of BOMAY and MIEFE in U.S. dollars was as follows at December 31, 2017 and 2016: BOMAY MIEFE 2017 2016 2017 2016 Assets: Total current assets $ 50,000 $ 47,700 $ 121 $ 425 Total non-current assets 3,457 3,589 15 17 Total assets $ 53,457 $ 51,289 $ 136 $ 442 Liabilities and equity: Total liabilities $ 25,598 $ 24,196 $ 198 $ 551 Total joint ventures’ equity 27,859 27,093 (62 ) (109 ) Total liabilities and equity $ 53,457 $ 51,289 $ 136 $ 442 Twelve Months Ended December 31, BOMAY MIEFE 2017 2016 2017 2016 Revenue $ 26,168 $ 33,468 $ 89 $ 1,167 Gross Profit $ 5,654 $ 6,687 $ 23 $ 481 Earnings $ 1,084 $ 2,010 $ 55 $ (631 ) The Company’s investments in and advances to its foreign joint ventures’ operations were as follows as of December 31, 2017 and 2016: 2017 2016 BOMAY* MIEFE TOTAL BOMAY* MIEFE TOTAL (in thousands) (in thousands) Investments in foreign joint ventures: Balance, beginning of year $ 2,033 $ 14 $ 2,047 $ 2,033 $ 14 $ 2,047 Additional amounts invested and advanced - - - - - - Balance, end of year 2,033 14 2,047 2,033 14 2,047 Undistributed earnings: Balance, beginning of year 8,313 (14 ) 8,299 8,098 (11 ) 8,087 Equity in earnings (loss) 434 - 434 804 (3 ) 801 Dividend distributions (780 ) - (780 ) (589 ) - (589 ) Balance, end of year 7,967 (14 ) 7,953 8,313 (14 ) 8,299 Foreign currency translation: Balance, beginning of year 104 213 317 765 205 970 Change, during the year 633 (3 ) 630 (661 ) 8 (653 ) Balance, end of year 737 210 947 104 213 317 Investments, end of year $ 10,737 $ 210 $ 10,947 $ 10,450 $ 213 $ 10,663 Accumulated statutory reserves in equity method investments of $2.81 million and $2.89 million at December 31, 2017 and 2016, are included in AETI’s consolidated retained earnings. In accordance with the People’s Republic of China, (“PRC”), regulations on enterprises with foreign ownership, an enterprise established in the PRC with wholly-owned foreign ownership is required to provide for certain statutory reserves, namely (i) General Reserve Fund, (ii) Enterprise Expansion Fund and (iii) Staff Welfare and Bonus Fund, which are appropriated from net profit as reported in the enterprise’s PRC statutory accounts. A non-wholly-owned foreign invested enterprise is permitted to provide for the above allocation at the discretion of its board of directors. The aforementioned reserves can only be used for specific purposes and are not distributable as cash dividends. The Company accounts for its investments in foreign joint ventures’ operations using the equity method of accounting. Under the equity method, the Company’s share of the joint ventures’ operations’ earnings or losses is recognized in the consolidated statements of operations as equity income (loss) from foreign joint ventures’ operations. Joint venture income increases the carrying value of the joint ventures and joint venture losses reduce the carrying value. Dividends received from the joint ventures reduce the carrying value. In accordance with our long-lived asset policy, when events or circumstances indicate the carrying amount of an asset may not be recoverable, management tests long-lived assets for impairment. If the estimated future cash flows are projected to be less than the carrying amount, an impairment write-down (representing the carrying amount of the long-lived asset which exceeds the present value of estimated expected future cash flows) would be recorded as a period expense. In making this evaluation, a variety of quantitative and qualitative factors are considered including national and local economic, political and market conditions, industry trends and prospects, liquidity and capital resources and other pertinent factors. Based on this evaluation for this reporting period, the Company does not believe an impairment adjustment is necessary.

(the “Purchaser”) a $7.00 million principal amount Senior Secured Term Note (the “Note”) with principal of $0.50 million due and paid on June 30, 2017 with the balance due 48 months after issuance for cash at par pursuant to a Note Purchase Agreement (the “Purchase Agreement”). Proceeds from the sale of the Note were used to fully repay and terminate the Company’s prior revolving credit facilities with approximately $1.00 million being available for the Company’s working capital and general business purposes. The Note bears interest at 11.5% per annum payable monthly in arrears. The Note is secured by a first-priority lien on substantially all existing and after-acquired personal property assets and real estate owned by the Sellers (with certain exceptions). The Note is subject to an interest “make-whole” provision such that any prepayment of the principal thereunder in excess of $1.50 million (the “Prepayment Threshold”) within one year of the date of issuance (the “Make-Whole Period”) shall be subject to the payment of a prepayment premium, on the date of such prepayment, in an amount based on an interest rate of 11.5% per annum of the prepayment amount in excess of the Prepayment Threshold for the portion of the Make-Whole Period that will remain after the date that the prepayment is made. After the one year Make- Whole Period the Note may be prepaid in part or in full with no penalty. The Purchase Agreement contains representations and affirmative, negative and financial covenants usual and customary for financing of this type, including covenants that place conditions upon the Company’s ability to merge or consolidate with other companies, sell any material part of their business or property, incur liens, and pay dividends on, make distributions on or redeem their equity interests. Other covenants in the Purchase Agreement require the Company to maintain minimum monthly revenue, maintain minimum monthly EBITDA, maintain minimum monthly cash on hand, maintain a minimum monthly debt service coverage ratio, maintain a maximum debt-to-EBITDA ratio, maintain a minimum monthly collateral coverage ratio and obtain consent of the Purchaser for certain capital expenditure. In the event that the Company fails to meet covenants in the future, the Company may not be able to obtain the necessary waivers or amendments to remain in compliance with the Purchase Agreement and the Purchaser may declare a default and cause all of the Company’s outstanding indebtedness under the Purchase Agreement to become immediately due and payable or otherwise subject to an additional rate of 4.0% per annum and scheduled amortization of principal. The fair value assigned to the warrants of approximately $0.37 million was recognized as an increase in additional paid-in-capital with a corresponding discount on the notes payable. The discount is accreted through interest expense over the remaining term of the note payable.The fair value of the warrants was calculated using the Black Scholes-Merton pricing model using the following weighted average assumptions, at the grant date: Number of warrants 500,000 Exercise price $ 2.26 Expected volatility of underlying stock 72 % Risk-free interest rate 2.08 % Dividend yield 0 % Expected life of warrants 5 years Weighted-average fair value of warrants $ 0.73 Expiration date November 13, 2022

The following table summarizes the activity for unvested restricted stock units for the years ended December 31, 2017 and 2016: Units Weighted Unvested restricted stock units at December 31, 2015 315,847 $ 3.99 Awarded 31,327 $ 2.81 Vested (105,443) $ 4.66 Forfeited (23,319) $ 5.12 Unvested restricted stock units at December 31, 2016 218,412 $ 4.28 Awarded 56,759 $ 1.48 Vested (112,340) $ 3.99 Forfeited (2,289) $ 4.41 Unvested restricted stock units at December 31, 2017 165,120 $ 3.40 Compensation expense of approximately $0.30 million and $0.49 million was recorded in the years ended December 31, 2017 and 2016, respectively, to reflect the fair value of the original RSU’s granted or anticipated to be granted less forfeitures, amortized over the portion of the vesting period occurring during the period. The fair value of the RSUs was based on the closing price of our common stock as reported on the NASDAQ Stock Market (“NASDAQ”) on the grant date. Based upon the fair value on the grant date of the number of shares awarded or expected to be awarded, it is anticipated that approximately $0.56 million of additional compensation cost will be recognized in future periods through 2020. The weighted average period over which this additional compensation cost will be expensed is 3 years. In December 2016, the Board of Directors approved modification to the requisite service period to accelerate vesting for 75% of the RSU granted to employees for the year ended December 31, 2016. During February 2017, the Board of Directors approved the grants of approximately 605,000 RSUs in conjunction with the Plan, of which, approximately 541,000 units are subject to 2018 fiscal performance measures. Board of Directors Deferred Compensation Directors who are not employees of the Company and who do not have a compensatory agreement providing for service as a director of the Company receive a retainer fee payable quarterly. Eligible directors may elect to defer 50% to 100% of their retainer fee, which may be used to acquire common stock of the Company at the fair market value on the date the retainer fee would otherwise be paid, acquire stock units equivalent to the fair market value of the Company’s common stock on the date the retainer fee would otherwise be paid, or be paid in cash. During the years ended December 31, 2017 and 2016, directors of the Company elected to defer retainer fees to acquire approximately 72,000 and 73,750 respectively, stock units. Compensation expense of approximately $0.08 million and $0.07 million was recorded in the years ended December 31, 2017 and 2016 respectively, which is included in general and administrative expenses in the consolidated statements of operations.

Temporary Equity Disclosure [Abstract]
Redeemable Convertible Preferred Stock	( 11) Redeemable Convertible Preferred Stock On April 13, 2012, the Company signed a securities purchase agreement (the “Securities Purchase Agreement”) with a private investor for the sale (the “Preferred Stock Financing”) of 1,000,000 shares of the Company’s Series A Convertible Preferred Stock (the “Series A Convertible Preferred Stock”) at $5.00 per share and 325,000 warrants to purchase shares of the Company’s common stock expiring in May 2020. The Series A Convertible Preferred Stock shares are initially convertible into 1,000,000 shares of the Company’s common stock at a conversion price of $5.00 per share. The warrants were issued in two tranches with 125,000 of such warrants at an initial exercise price of $6.00 per share and 200,000 of such warrants at an initial exercise price of $7.00 per share. On May 2, 2012, the Company completed the issuance of the Series A Convertible Preferred Stock and warrants. On April 30, 2012, the Company filed an Articles of Amendment to its Articles of Incorporation designating 1,000,000 shares of the Company’s authorized preferred stock as Series A Convertible Preferred Stock. The Company also entered into a Registration Rights Agreement and Investor Rights Agreement with the private investor. The Series A Convertible Preferred Stock ranks senior to all other equity instruments of the Company, including the Company’s common stock. The Series A Convertible Preferred Stock accrues cumulative dividends at a rate of 6% per annum, whether or not dividends have been declared by the Board of Directors and whether or not there are profits, surplus or other funds available for the payment of such dividends. The Company may pay such dividends in shares of the Company’s common stock based on the then current market price of the common stock. Prior to the repricing agreement discussed below, at any time following a material default by the Company, as defined in the Securities Purchase Agreement, or April 30, 2017, the holders of a majority of the outstanding shares of the Series A Convertible Preferred Stock may require the Company to redeem the Series A Convertible Preferred Stock at a redemption price equal to the lessor of (i) the liquidation preference per share (initially $5.00 per share, subject to adjustments for certain future equity transactions defined in the Securities Purchase Agreement) and (ii) the fair market value of the Series A Convertible Preferred Stock per share, as determined in good faith by the Company’s Board of Directors. As of December 31, 2017 and 2016, the redemption price per share was $5.00 in both years. The redemption price, plus any accrued and unpaid dividends, shall be payable in 36 equal monthly installments plus interest at an annual rate of 6%. The preferred stock and warrants were issued for a total of $5.0 million. This amount was allocated to the preferred stock and warrants based on their relative fair values. The fair value of the warrants was calculated using the Black Scholes-Merton pricing model using the following weighted average assumptions, at the grant date: Number of warrants 325,000 Exercise price $ 6.62 Expected volatility of underlying stock 74 % Risk-free interest rate 1.62 % Dividend yield 0 % Expected life of warrants 8 years Weighted-average fair value of warrants $ 3.11 Expiration date May 2, 2020 Based on these calculations and the actual consideration, the warrants were valued at $840,000 and the Series A Convertible Preferred Stock was valued at $4,160,000. The initial values allocated to the warrants were recognized as a discount on the Series A Convertible Preferred Stock, with a corresponding charge to additional paid-in capital. The discount related to the warrants is accreted to retained earnings through the scheduled redemption date of the mandatorily redeemable Series A Convertible Preferred Stock. Discount accretion for the years ended December 31, 2017 and 2016 totaled $0.06 million and $0.05 million, respectively. At December 31, 2017 and December 31, 2016, the company had accrued but unpaid dividends totaling $0.08 million and $0.23, respectively, which is included in the accounts payable and other accrued expenses in the consolidated balance sheets. In connection with the issuance of the Company’s senior secured Term Note, described in Note 8, the Company has agreed with the Purchaser of the Term Note and the holder of the Preferred Stock (the “Holder”) not to declare, authorize or pay any cash dividends on the Preferred Stock until the earlier of (i) March 22, 2018, or (ii) the date the obligations under the Note Purchase Agreement have been paid in full (the “Standstill Period”), without the prior written consent of the Purchaser. Following the expiration of the Standstill Period, for so long as the obligations under the Note Purchase Agreement remain outstanding, the Company may, at its sole discretion, declare, authorize or pay dividends in cash on the Preferred Stock so long as no event of default exists under the Term Note or would result therefrom. The Holder also agreed that it shall not exercise its rights to require the Company to redeem any of the Preferred Stock during the Standstill Period. Following the expiration of the Standstill Period, so long as the obligations under the Note Purchase Agreement remain outstanding, the Holder may compel the Company to redeem shares of Preferred Stock provided no event of default exists under the Term Note or would result from such redemption. In consideration for the Holder’s consent to the foregoing restrictions on the payment of cash dividends on or redemption of the Preferred Stock, the Company entered into a repricing agreement with the Holder (the “Repricing Agreement”) on August 1, 2017. Pursuant to the repricing agreement, each share of Series A Preferred Stock will be initially convertible, at the option of the holder, into one (1) share of common stock at a conversion price of $2.26 per share of common stock, so that the Series A Preferred Stock sold to the Holder are currently convertible into an aggregate of 2,212,389 shares of common stock as of December 31, 2017. In addition, Pursuant to the Repricing Agreement, the Series A Warrants sold to the Holder is exercisable for 125,000 shares of common stock at an initial exercise price of $2.72 per share and the Series B Warrants sold to the Holder is exercisable for 200,000 shares of common stock at an initial exercise price of $3.17 per share. In order to comply with the rules of the NASDAQ Stock Market, the Repricing Agreement prohibits the issuance of more than 19.99% of our common stock or voting power outstanding to the Holder as of the date of the Repricing Agreement without stockholder approval. The Company has agreed to seek the approval of its stockholders as soon as practicable. In the event that stockholder approval is received and the Holder were to convert all of its Series A Preferred Stock into common stock and exercised all of its Common Stock Purchase Warrants for cash, the Holder would be issued more than 19.99% of our common stock and voting power as of the date of the Repricing Agreement. This agreement was approved by a committee of the Board of Directors comprised solely of independent directors.

Summary of Significant Accoun27

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2017
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include the accounts of AETI and its wholly-owned subsidiaries, M&I and M&I Brazil, and the assets of SCES through the disposition date in June 2016. Significant intercompany accounts and transactions are eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of net sales and expenses during the reporting period. Actual results could differ from those estimates. The most significant estimates made by management include: (1) Percentage-of-completion estimates on long-term contracts (2) Estimates of the provision for doubtful accounts (3) Estimated useful lives of property and equipment (4) Valuation allowances related to deferred tax assets As future events and their effects cannot be determined with absolute certainty, actual results may differ from the estimates used in preparing the accompanying consolidated financial statements. Significant estimates and assumptions are required as part of determining inventory and accounts receivable valuation, estimating depreciation, amortization and recoverability of long-lived assets, establishing self-insurance, warranty, legal and other reserves, performing intangible impairment analyses, and in establishing valuation allowances on deferred income tax assets and reserves for tax examination exposures.
Financial Instruments	Financial Instruments The Company includes fair value information in the notes to the consolidated financial statements when the fair value of its financial instruments is different from the book value. When the book value approximates fair value, no additional disclosure is made, which is the case for financial instruments outstanding as of December 31, 2017 and 2016. The Company assumes the book value of those financial instruments that are classified as current approximates fair value because of the short maturity of these instruments. For non-current financial instruments, the Company uses quoted market prices or, to the extent that there are no available quoted market prices, market prices for similar instruments.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash equivalents consist of liquid investments with original maturities of three months or less. Cash balances routinely exceed FDIC limits however all cash is maintained in JP Morgan Chase and Frost Bank and believed to be secure.
Short-term Investments	Short-term investments Short-term investments consist of any fund held in certificate of deposit with original maturities greater than three months and investments in debt and equity securities with maturity of one year or less.
Accounts Receivable and Allowance for Bad Debts	Accounts Receivable and Allowance for Bad Debts The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The estimate is based on management’s assessment of the collectability of specific customer accounts and includes consideration for credit worthiness and financial condition of those specific customers. The Company also reviews historical experience with the customer, the general economic environment and the aging of its receivables. The Company records an allowance to reduce receivables to the amount it reasonably believes to be collectible. Based on this assessment, management believes the allowance for doubtful accounts is adequate. The bad debt expense was a net recovery of ($0.13) million and expense of $0.21 million for the fiscal years ended December 31, 2017 and 2016.
Inventories	Inventories Inventories are stated at the lower of cost or market, with material value determined using an average cost method. Inventory costs for work-in-process include direct material, direct labor, production overhead and outside services. Indirect overhead is apportioned to work-in-process based on direct labor incurred.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are stated at cost. Expenditures for repairs and maintenance are expensed as incurred while renewals and betterments are capitalized. Depreciation is calculated on the straight-line basis over the estimated useful lives of the assets after giving effect to salvage values.
Long-lived assets	Long-lived assets If events or circumstances indicate the carrying amount of an asset may not be recoverable, including intangible assets, management tests long-lived assets for impairment. If the estimated future cash flows are projected to be less than the carrying amount, an impairment write-down (representing the carrying amount of the long-lived asset which exceeds the present value of estimated expected future cash flows) would be recorded as a period expense. Events that would trigger an impairment test include the following: • A significant decrease in the market price of a long-lived asset. • A significant change in the use of long-lived assets or in its physical condition. • A significant change in the business climate that could affect an assets value. • An accumulation of cost significantly greater than the amount originally expected to acquire or construct a long-lived asset. • A current period operating or cash flow loss combined with a history of such losses or a forecast demonstrating continued losses associated with the use of a long-lived asset. • An expectation to sell or otherwise dispose of a long-lived asset significantly before the end of its estimated useful life. Based on management’s reviews during each of the years ended December 31, 2017 and 2016, there were no events or circumstances that caused management to believe that impairments were necessary.
Intangible Assets	Intangible Assets Intangible Assets at December 31, 2017 Useful Cost Accumulated Net Value (in thousands) Intellectual property 3 $ 322 $ 322 $ - License 5 358 118 240 License - 218 - 218 $ 898 $ 440 $ 458 During 2014 we acquired arc-resistant technology and capitalized the cost of $0.22 million. During 2016, the Company capitalized cost of $0.36 million for the testing associated with certifications for IntelliSafe™ products. The cost is being amortized over its useful life of 5 years. Amortization expense of $0.07 million and $0.05 million was recognized during the year ended December 31, 2017 and 2016, respectively, and is included in the cost of sales in the consolidated statements of operations.
Income Taxes	Income Taxes The Company uses the asset and liability method to account for income taxes. Under this method of accounting for income taxes, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using the enacted tax rates and laws that will be in effect when the differences are expected to be reported to the taxing authority. The Company also records any financial statement recognition and disclosure requirements for uncertain tax positions taken or expected to be taken in its tax return. Financial statement recognition of the tax position is dependent on an assessment of a 50% or greater likelihood that the tax position will be sustained upon examination, based on the technical merits of the position. Any interest and penalties related to uncertain tax positions are recorded as interest expense in the accompanying consolidated statements of operations.
Foreign Currency Gains and Losses	Foreign Currency Gains and Losses Foreign currency translations are included as a separate component of comprehensive income. The Company has determined the local currency of its foreign subsidiary and foreign joint ventures to be the functional currency. In accordance with ASC 830, the assets and liabilities of the foreign equity investees and foreign subsidiary, denominated in foreign currency, are translated into United States dollars at exchange rates in effect at the consolidated balance sheet date and net sales and expenses are translated at the average exchange rate for the period. Related translation adjustments are reported as comprehensive income, net of deferred income taxes, which is a separate component of stockholders’ equity, whereas gains and losses resulting from foreign currency transactions are included in results of operations.
Net Sales Recognition	Net Sales Recognition The Company reports earnings from fixed-price and modified fixed-price long-term contracts on the percentage-of-completion method. Earnings are accrued based on the ratio of costs incurred to total estimated costs. However, for our manufacturing activities, we have determined that labor incurred provides an improved measure of percentage-of-completion. Costs include direct material, direct labor, and job related overhead. Losses expected to be incurred on contracts are charged to operations in the period such losses are determined. A contract is considered complete when all costs except insignificant items have been incurred and the facility has been accepted by the customer. Net sales from non-time and material jobs of a short-term nature (typically less than one month) are recognized on the completed-contract method after considering the attributes of such contracts. This method is used because these contracts are typically completed in a short period of time and the financial position and results of operations do not vary materially from those which would result from use of the percentage-of-completion method. The Company records net sales from its time and material projects on a completed service basis after customer acknowledgement that the service has been completed and accepted. In addition, the Company sells certain purchased parts and products. These net sales are recorded when the product is shipped and title passes to the customer. The asset, “Work-in-process,” which is included in inventories, represents the cost of labor, material, and overhead in excess of amounts billed on jobs accounted for under the completed-contract method. For contracts accounted for under the percentage-of-completion method, the asset, “Costs and estimated earnings in excess of billing on uncompleted contracts,” represents net sales recognized in excess of amounts billed and the liability, “Billings in excess of costs and estimated earnings on uncompleted contracts,” represents billings in excess of net sales recognized. Any billed net sale that has not been collected is reported as accounts receivable. The timing of when we bill our customers is generally dependent upon advance billing terms or completion of certain phases of the work. On occasion, the Company enters into long-term contracts that include both a service component and a manufacturing component. For segmented contracts, the Company recognizes net sales as if they were separate contracts over the performance periods of the individual elements. Contract net sales recognition inherently involves estimation, including the contemplated level of effort to accomplish the tasks under the contract, the cost of the effort, and an ongoing assessment of progress toward completing the contract. From time to time, as part of the normal management processes, facts develop that requires revisions to estimated total cost or net sales expected. The cumulative impact of any revisions to estimates and the full impact of anticipated losses on contracts are recognized in the period in which they become known.
Shipping and Handling Fees and Costs	Shipping and Handling Fees and Costs Shipping and handling fees, if billed to customers, are included in net sales. Shipping and handling costs associated with inbound freight are expensed as incurred. Shipping and handling costs associated with outbound freight are classified as cost of sales.
Uses and Sources of Liquidity	Uses and Sources of Liquidity The Company’s primary need for liquidity is to fund working capital requirements of the Company’s businesses, capital expenditures and for general corporate purposes, including debt repayment. The Company has incurred losses and experienced negative operating cash flows for the past several years, and accordingly, the Company has taken a number of actions to continue to support its operations and meet its obligations. During 2016, the Company undertook actions to monetize the value of certain of its assets which included disposition of the manufacturing facility and related assets in Bay St. Louis Mississippi. During 2017, the Company refinanced its outstanding loans which at that time provided approximately $1.0 million of working capital. In addition, the Board of Directors of the Company created a special committee to address strategic initiatives that include addressing liquidity. The Company continues to face a challenging competitive environment and while it continues to focus on its overall profitability, including managing expenses, it reported a loss in 2017 and was required to fund cash used in operating activities with cash from investing and financing activities. Going forward, the Company expects to generate additional liquidity from strategic initiatives including monetization of assets and additional debt and equity financing actions. The Company expects that these actions will be executed in alignment with the anticipated timing of its liquidity needs. The Company also continues to explore ways to unlock value across a range of assets, including exploring ways to maximize the value of its manufacturing facility in Beaumont, Texas. The Company expects to continue to optimize both international and domestic operations including expansion of its service business in Brazil and diversification of its joint venture operations in China. The Company’s historical operating results indicate substantial doubt exists related to its ability to continue as a going concern. However, the Company believes it is probable that the actions discussed above will occur and mitigate the substantial doubt raised by its historical operating results and satisfy its estimated liquidity needs 12 months from the issuance of the financial statements. However, the Company cannot predict, with certainty, the outcome of its actions to generate liquidity, including the availability of additional debt financing, or whether such actions would generate the expected liquidity as currently planned. In addition, the current Senior Secured Note and Redeemable Preferred Stock both contain certain limitations on our ability to sell assets, which could impact its ability to complete asset sale transactions or its ability to use proceeds from those transactions to fund our operations. Therefore, any planned actions must take into account the ability to transact within any applicable restrictions under these agreements. If the Company continues to experience operating losses, and is not able to generate additional liquidity through the mechanisms described above or through some combination of other actions, while not expected, it may not be able to access additional liquidity and we might need to secure additional sources of funds, which may or may not be available to us. Additionally, a failure to generate additional liquidity could negatively impact the Company’s access to materials or services that are important to the operation of its business.
Concentration of Market Risk and Geographic Operations	Concentration of Market Risk and Geographic Operations Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of trade accounts receivable. The Company’s market risk is dependent primarily on the strength of the oil and gas and energy related industries. The Company grants credit to customers and generally does not require security except in the case of certain international contracts. Procedures are in effect to monitor the credit worthiness of its customers. The Company sells its products and services in domestic and international markets; however, significant portions of the Company’s sales are concentrated with customers located in the Gulf Coast region of the United States. The Gulf Coast region accounts for approximately 8% and 47% of the Company’s net sales during the years ended December 31, 2017 and 2016, respectively.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers, which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of ASU No. 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU No. 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required under existing U.S. GAAP. The standard is effective for annual periods beginning after December 15, 2016, and interim periods therein, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU No. 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). In July 2015, the FASB issued ASU No. 2015-14 which delayed the effective date of ASU No. 2014-09 by one year (effective for annual periods beginning after December 15, 2017). The Company adopted ASU 2014-09, effective January 1, 2018, using the modified retrospective method. The adoption of the standard will not have a material impact on the Company’s revenue recognition policies, other than enhanced disclosures related to the disaggregation of revenues from contracts with customers, the Company’s performance obligations and any significant judgments. In August 2014, the FASB issued an accounting standards update which requires management to assess whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the financial statements are issued. If substantial doubt exists, additional disclosures are required. This update was effective for the Company's annual period ended December 31, 2016. The Company's assessment of our ability to continue as a going concern is further discussed in the "Uses and Sources of Liquidity" paragraph above. The adoption of the new standard did not have a material impact on the Company’s consolidated financial position, results of operations, cash flows or disclosures. In July 2015, the FASB issued ASU No. 2015-11. Inventory (Topic 330): Simplifying the Measurement of Inventory, which is intended to converge U.S. GAAP on this topic with International Financial Reporting Standards (“IFRS”). ASU No. 2015-11 focuses on the premeasurement of inventory measured using any method other than LIFO, for example, average cost. Inventory within the scope of ASU No. 2015-11 is required to be measured at the lower of cost and net realizable value. When evidence exists that the net realizable value of inventory is lower than its cost, the difference shall be recognized as a loss in earnings in the period in which it occurs. That loss may be required, for example, due to damage, physical deterioration, obsolescence, changes in price levels, or other causes. For public business entities, the amendments in ASU No. 2015-11 are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The adoption of ASU No. 2015-11 did not have a significant impact on the Company’s consolidated financial position, results of operations and disclosures. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. ASU No. 2016-01 requires (1) an entity to measure equity instruments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) at fair value with changes in fair value recognized in net income; (2) entities to use the exit price notation when measuring the fair value of financial instruments for disclosure purposes; (3) separate presentation of financial assets and financial liabilities by measurement category and form of financial asset; and (4) elimination of the requirement to disclose the methods and significant assumptions used to estimate fair value that is required to be disclosed for financial instruments measured at amortized cost. ASU No. 2016-01 is effective for fiscal years beginning after December 15, 2017 with early adoption permitted. Management is currently evaluating the future impact of ASU No. 2016-01 on the Company’s consolidated financial position, results of operations and disclosures. In February 2016, the FASB issued ASU No. 2016-02, Leases, which requires lessees to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under ASU No. 2016-02, lessor accounting is largely unchanged. ASU No. 2016-02 is effective for fiscal years beginning after December 15, 2018 with early application permitted. Lessees and lessors must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases expiring before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. Management is currently reviewing the Company’s various leases to identify those affected by ASU No. 2016-02. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, to clarify two aspects of Topic 606: (i) identifying performance obligations; and (ii) the licensing implementation guidance. The amendments do not change the core principle of the guidance in Topic 606. The effective date and transition requirements for ASU No. 2016-10 are the same as the effective date and transition requirements for ASU No. 2014-09. This standard was adopted effective January 1, 2018, see ASU No. 2014-09 above for additional information. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients. ASU No. 2016-12 provides narrow-scope improvements to the guidance on collectability, noncash consideration, and completed contracts at transition. The amendment also provides a practical expedient for contract modifications at transition and an accounting policy election related to the presentation of sales taxes and other similar taxes collected from customers and are expected to reduce the judgment necessary to comply with Topic 606. The effective date and transition requirements for ASU No. 2016-12 are the same as the effective date and transition requirements for ASU No. 2014-09. This standard was adopted effective January 1, 2018, see ASU No. 2014-09 above for additional information. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU No. 2016-13 eliminates the probable initial recognition threshold in current U.S. GAAP and, instead, requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. In addition, ASU No. 2016-13 amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. ASU No. 2016-13 is effective for annual periods beginning after December 15, 2019, with early application permitted in annual periods beginning after December 15, 2018. The amendments of ASU No. 2016-13 should be applied through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. Management is currently evaluating the future impact of ASU No. 2016-13 on the Company’s consolidated financial position, results of operations and disclosures. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. ASU No. 2016-15 addresses eight specific cash flow issues and is intended to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. ASU No. 2016-15 is effective for reporting periods beginning after December 15, 2017. Early adoption is permitted. Management does not expect the adoption of ASU No. 2016-15 to have a significant impact on the Company’s consolidated financial position, results of operations and disclosures because it only affects presentation of specific items within the cash flow statement. In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers. ASU No. 2016-20 allows entities not to make quantitative disclosures about remaining performance obligations in certain cases and require entities that use any of the new or previously existing optional exemptions to expand their qualitative disclosures. The amendment also clarifies narrow aspects of ASC 606, including contract modifications, contract costs, and the balance sheet classification of items as contract assets versus receivables, or corrects unintended application of the guidance. The effective date and transition requirements for ASU No. 2016-20 are the same as the effective date and transition requirements for ASU No. 2014-09. Management is currently evaluating the future impact of ASU No. 2016-20 on the Company’s consolidated financial position, results of operations and disclosures. Please refer to ASU No. 2014-09 above. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. ASU No. 2017-01 clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of a business or as acquisitions (or disposals) of assets. ASU No. 2017-01 is effective for annual periods beginning after December 15, 2018, with early adoption permitted under certain circumstances. The amendments of ASU No. 2017-01 should be applied prospectively as of the beginning of the period of adoption. Management is currently evaluating the future impact of ASU No. 2017-01 on the Company’s consolidated financial position, results of operations and disclosures. In January 2017, the FASB issued ASU No. 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments – Equity Method and Joint Ventures (Topic 323): Amendments to SEC Paragraphs Pursuant to Staff Announcements at the September 22, 2016 and November 17, 2016 EITF Meetings. The amendments in this update relate to disclosures of the impact of recently issued accounting standards. The SEC staff’s view that a registrant should evaluate ASC updates that have not yet been adopted to determine the appropriate financial disclosures about the potential material effects of the updates on the financial statements when adopted. If a registrant does not know or cannot reasonably estimate the impact of an update, then in addition to making a statement to that effect, the registrant should consider additional qualitative financial statement disclosures to assist the reader in assessing the significance of the impact. The staff expects the additional qualitative disclosures to include a description of the effect of the accounting policies expected to be applied compared to current accounting policies. Also, the registrant should describe the status of its process to implement the new standards and the significant implementation matters yet to be addressed. The amendments specifically addressed recent ASC amendments to ASU No. 2016-13, Financial Instruments – Credit Losses, ASU No. 2016-02, Leases, and ASU No. 2014-09, Revenue from Contracts with Customers, although, the amendments apply to any subsequent amendments to guidance in the ASC. ASU No. 2017-03 is effective upon issuance and did not have a significant impact on the Company’s consolidated financial position, results of operations and disclosures.
