Summary of Certain Significant Accounting Policies	2. Summary of Certain Significant Accounting Policies Adoption of New Revenue Recognition Standard 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 did 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 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. 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. 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. The Company recognizes revenue when or as it satisfies a performance obligation by transferring promised goods or service to a customer using the over-time method to account for certain long-term contracts and point in time method for non-time and material jobs. The non-time and material jobs are of a short-term nature (typically less than one month) and are determined 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. Earnings are accrued based on the ratio of costs incurred to total estimated costs. Costs include direct material, direct labor, and job related overhead. For our manufacturing activities we have determined that labor incurred, rather than total costs incurred, provides an improved measure of percentage-of-completion. For contracts with anticipated losses, the estimated losses are charged to operations in the period such losses are determined. The asset, “Work-in-process,” which is included in inventories, represents the cost of labor, material, and overhead on jobs accounted for point in time method for non-time and material jobs. The contract asset, “Costs and estimated earnings in excess of billings on uncompleted contracts,” represents revenue recognized in excess of amounts billed and the contract-liability. “Billings in excess of costs and estimated earnings on uncompleted contracts,” represents billings in excess of revenue recognized under the percentage-of-completion method. Due to the nature of these projects, the estimation of total revenue and cost at completion is subject to many variables and requires significant judgement. Progress billings are generally issued upon completion of certain milestones of the project as specified in the contract. Costs and estimated earnings in excess of billings on uncompleted contracts was $4.3 million at March 31, 2018 and $6.4 million at December 31, 2017. Billings in excess of costs and estimated earnings on uncompleted contracts was $2.3 million at March 31, 2018 and $ 1.8 million at December 31, 2017. The order backlog at March 31, 2018 and December 31, 2017 was $24.9 million and $18.9 million, respectively. This backlog is expected to be recognized in revenue during the remainder of 2018 and 2019. 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 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 Q1 2018 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 has taken a number of actions including the hiring on an investment banker to address liquidity in the near term and 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 or finding suitable sources of financing alternatives. 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 also has the ability to raise additional capital through its shelf registration; however, there is no assurance that additional capital can be obtained or that it can be obtained at terms that are favorable to the Company and its existing stockholders. 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.
