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 accounts 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 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, 2016 and 2015. 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 maturity 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 $0.21 million and $0.17 million for the fiscal years ended December 31, 2016 and 2015. 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, 2016 and 2015, there were no events or circumstances that caused management to believe that impairments were necessary. Intangible Assets Intangible Assets at December 31, 2016 Useful Cost Accumulated Net Value (in thousands) Intellectual property 3 $ 322 $ 322 $ - License 5 358 49 309 License - 218 - 218 $ 898 $ 371 $ 527 On March 8, 2012, the Company acquired certain technology from Amnor Technologies, Inc. for cash of $0.10 million plus 44,000 shares of the Company’s common stock valued at $4.95 per share (the closing price on that date). One fourth of the shares were issued initially with the balance to be issued one third annually on the anniversaries over the subsequent 3 years. The purchase price was valued at $0.32 million (including $4,000 of transaction costs) at March 8, 2012 and is recorded as an intangible asset in the consolidated balance sheets. The cost was being amortized over its estimated useful life of 3 years which expired in 2015. Amortization expense of $0.02 million was recognized during the year ended December 31, 2015 and is included in general and administrative expenses in the consolidated statements of operations. The technology provides automation and control system technologies for land and offshore drilling monitoring and control (auto-driller); marine automation including ballast control and tank monitoring and machinery plant control and monitoring systems; IP-based CCTV systems; and military vessel security and safety systems, all proven in multiple installations. 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 $0.05 million was recognized during the year ended December 31, 2016 and is included in the cost of sales in the consolidated statements of operations. 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. 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 field and technical service and repair operations 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. The Company segments net sales, costs and gross profit related to these contracts if they meet the contract segmenting criteria in ASC 605-35, including that the terms and scope of the project clearly call for separate elements, the separate elements are often bid or negotiated by the Company separately and the total economic returns and risks of the separate elements are similar to the economic returns and risks of the overall contract. 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. 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 47% and 68% of the Company’s net sales during the years ended December 31, 2016 and 2015, respectively. Reclassification Certain items are reclassified in the 2015 consolidated financial statements to conform to the 2016 presentation. Such reclassifications had no effect on the Company’s financial position, results of operations or cashflows.

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.

Restricted Stock Units As amended in May 2014, the stockholder approved shares available under the plan is 1,700,000. The number of RSUs awarded is generally subject to the substantial achievement of budgeted performance and other metrics in the year granted. The RSUs do not have voting rights of the common stock, and the shares of common stock underlying the RSUs are not considered issued and outstanding until actually vested and issued. In general, the awards convert to common stock on a one to one basis in 25% increments over four years from the grant date subject to a continuing employment obligation. The following table summarizes the activity for unvested restricted stock units for the years ended December 31, 2016 and 2015: Units Weighted Unvested restricted stock units at December 31, 2014 168,642 $ 4.88 Awarded 231,356 $ 3.47 Vested (72,298) $ 4.44 Forfeited (11,853) $ 4.55 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 Compensation expense of approximately $0.49 million and $0.46 million was recorded in the years ended December 31, 2016 and 2015, 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 $0.93 million of additional compensation cost will be recognized in future periods through 2017. The weighted average period over which this additional compensation cost will be expensed is 2 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 2016 plan. During February 2017, the Board of Directors approved the grants of approximately 395,000 RSUs in conjunction with the Plan, of which, approximately 332,000 units are subject to 2017 fiscal performance measures. Board of Directors 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, 2016 and 2015, directors of the Company elected to defer retainer fees to acquire approximately 31,000 and 29,400, respectively, stock units.

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. 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, 2016 and 2015, 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, 2016 and 2015 totaled $0.05 million in both years. At December 31, 2016 and December 31, 2015, the company had accrued but unpaid dividends totaling $0.23 million, in both years, which is included in the accounts payable and other accrued expenses in the consolidated balance sheets.

Summary of Significant Accoun29

Summary of Significant Accounting Policies (Policies)	12 Months Ended

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 accounts 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
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, 2016 and 2015. 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 maturity 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 $0.21 million and $0.17 million for the fiscal years ended December 31, 2016 and 2015.
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, 2016 and 2015, there were no events or circumstances that caused management to believe that impairments were necessary.
Intangible Assets	Intangible Assets Intangible Assets at December 31, 2016 Useful Cost Accumulated Net Value (in thousands) Intellectual property 3 $ 322 $ 322 $ - License 5 358 49 309 License - 218 - 218 $ 898 $ 371 $ 527 On March 8, 2012, the Company acquired certain technology from Amnor Technologies, Inc. for cash of $0.10 million plus 44,000 shares of the Company’s common stock valued at $4.95 per share (the closing price on that date). One fourth of the shares were issued initially with the balance to be issued one third annually on the anniversaries over the subsequent 3 years. The purchase price was valued at $0.32 million (including $4,000 of transaction costs) at March 8, 2012 and is recorded as an intangible asset in the consolidated balance sheets. The cost was being amortized over its estimated useful life of 3 years which expired in 2015. Amortization expense of $0.02 million was recognized during the year ended December 31, 2015 and is included in general and administrative expenses in the consolidated statements of operations. The technology provides automation and control system technologies for land and offshore drilling monitoring and control (auto-driller); marine automation including ballast control and tank monitoring and machinery plant control and monitoring systems; IP-based CCTV systems; and military vessel security and safety systems, all proven in multiple installations. 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 $0.05 million was recognized during the year ended December 31, 2016 and is included in the cost of sales in the consolidated statements of operations. 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.
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 field and technical service and repair operations 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. The Company segments net sales, costs and gross profit related to these contracts if they meet the contract segmenting criteria in ASC 605-35, including that the terms and scope of the project clearly call for separate elements, the separate elements are often bid or negotiated by the Company separately and the total economic returns and risks of the separate elements are similar to the economic returns and risks of the overall contract. 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.
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 47% and 68% of the Company’s net sales during the years ended December 31, 2016 and 2015, respectively.
Reclassification	Reclassification Certain items are reclassified in the 2015 consolidated financial statements to conform to the 2016 presentation. Such reclassifications had no effect on the Company’s financial position, results of operations or cashflows.
