Accounting Policies [Abstract] | |
Description of Business | ACM Research, Inc. (“ACM”) and its subsidiaries (collectively with ACM, the “Company”) develop, manufacture and sell single-wafer wet cleaning equipment used to improve the manufacturing process and yield for advanced integrated chips. The Company markets and sells, under the brand name “Ultra C,” lines of equipment based on the Company’s proprietary Space Alternated Phase Shift (“SAPS”) and Timely Energized Bubble Oscillation (“TEBO”) technologies. These tools are designed to remove random defects from a wafer surface efficiently, without damaging the wafer or its features, even at increasingly advanced process nodes. ACM was incorporated in California in 1998, and it initially focused on developing tools for manufacturing process steps involving the integration of ultra low-K materials and copper. The Company’s early efforts focused on stress-free copper-polishing technology, and it sold tools based on that technology in the early 2000s. In 2006 the Company established its operational center in Shanghai in the People’s Republic of China (the “PRC”), where it operates through ACM’s subsidiary ACM Research (Shanghai), Inc. (“ACM Shanghai”). ACM Shanghai was formed to help establish and build relationships with integrated circuit manufacturers in the PRC, and the Company initially financed its Shanghai operations in part through sales of non-controlling equity interests in ACM Shanghai. In 2007 the Company began to focus its development efforts on single-wafer wet-cleaning solutions for the front-end chip fabrication process. The Company introduced its SAPS megasonic technology, which can be applied in wet wafer cleaning at numerous steps during the chip fabrication process, in 2009. It introduced its TEBO technology, which can be applied at numerous steps during the fabrication of small node two-dimensional conventional and three-dimensional patterned wafers, in March 2016. The Company has designed its equipment models for SAPS and TEBO solutions using a modular configuration that enables it to create a wet-cleaning tool meeting the specific requirements of a customer, while using pre-existing designs for chamber, electrical, chemical delivery and other modules. The Company also offers a range of custom-made equipment, including cleaners, coaters and developers, to back-end wafer assembly and packaging factories, principally in the PRC. In 2011 ACM Shanghai formed a wholly owned subsidiary in the PRC, ACM Research (Wuxi), Inc. (“ACM Wuxi”), to manage sales and service operations. In November 2016 ACM redomesticated from California to Delaware pursuant to a merger in which ACM Research, Inc., a California corporation, was merged into a newly formed, wholly owned Delaware subsidiary, also named ACM Research, Inc. In June 2017 ACM formed a wholly owned subsidiary in Hong Kong, CleanChip Technologies Limited (“CleanChip”), to act on the Company’s behalf in Asian markets outside the PRC by, for example, serving as a trading partner between ACM Shanghai and its customers, procuring raw materials and components, performing sales and marketing activities, and making strategic investments. In August 2017 ACM purchased 18.77% of ACM Shanghai’s equity interests held by Shanghai Science and Technology Venture Capital Co., Ltd. On November 8, 2017, ACM purchased the remaining 18.36% of ACM Shanghai’s equity interest held by Shanghai Pudong High-Tech Investment Co., Ltd. (“PDHTI”) and Shanghai Zhangjiang Science & Technology Venture Capital Co., Ltd. (“ZSTVC”). At December 31, 2017, ACM owned all of the outstanding equity interests of ACM Shanghai, and indirectly through ACM Shanghai, owned all of the outstanding equity interests of ACM Wuxi. On September 13, 2017, ACM effectuated a 1-for-3 reverse stock split of Class A and Class B common stock. Unless otherwise indicated, all share numbers, per share amount, share prices, exercise prices and conversion rates set forth in these notes and the accompanying condensed consolidated financial statements have been adjusted retrospectively to reflect the reverse stock split. On November 2, 2017, the Registration Statement on Form S-1 (File No. 333- 220451) for ACM’s initial public offering of Class A common stock (the “IPO”) was declared effective by the U.S. Securities and Exchange Commission. Shares of Class A common stock began trading on the Nasdaq Global Market on November 3, 2017, and the closing for the IPO was held on November 7, 2017. In December 2017 ACM formed a wholly owned subsidiary in the Republic of Korea, ACM Research Korea CO., LTD. (“ACM Korea”), to serve customers based in Republic of Korea and perform sales, marketing, research and development activities for new products and solutions. |

Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Basis of Presentation and Principles of Consolidation The consolidated accounts include ACM and its subsidiaries, ACM Shanghai, ACM Wuxi, CleanChip and ACM Korea. Subsidiaries are those entities in which ACM, directly and indirectly, controls more than one half of the voting power. All significant intercompany transactions and balances have been eliminated upon consolidation. The accompanying condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and the rules and regulations of the Securities and Exchange Commission (“SEC”) for reporting on Form 10-Q. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements herein. The unaudited condensed consolidated financial statements herein should be read in conjunction with the historical consolidated financial statements of the Company for the year ended December 31, 2017 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. The accompanying condensed consolidated balance sheet as of June 30, 2018, the condensed consolidated statements of operations and comprehensive income (loss) for the three and six months ended June 30, 2018 and 2017, and the condensed consolidated statements of cash flows for the six months ended June 30, 2018 and 2017 are unaudited. In the opinion of management, the unaudited condensed consolidated financial statements of the Company reflect all adjustments that are necessary for a fair presentation of the Company’s financial position and results of operations. Such adjustments are of a normal recurring nature, unless otherwise noted. The balance sheet as of June 30, 2018 and the results of operations for the three months and six months ended June 30, 2018 are not necessarily indicative of the results to be expected for any future period. Use of Estimates The preparation of condensed consolidated financial statements in conformity with 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 balance sheet date and the reported revenues and expenses during the reported period in the condensed consolidated financial statements and accompanying notes. The Company’s significant accounting estimates and assumptions include, but are not limited to, those used for the valuation and recognition of stock-based compensation arrangements and warrant liability, realization of deferred tax assets, assessment for impairment of long-lived assets, allowance for doubtful accounts, inventory valuation for excess and obsolete inventories, lower of cost and market value or net realizable value of inventories, depreciable lives of property and equipment, and useful life of intangible assets. Management of the Company believes that the estimates, judgments and assumptions are reasonable, based on information available at the time they are made. Actual results could differ materially from those estimates. Basic and Diluted Net Income (Loss) attributable to ACM per Common Share Basic and diluted net income (loss) attributable to ACM per common share is calculated as follows: Three Months Ended June 30, Six Months Ended June 30, 2018 2017 2018 2017 Numerator: Net income (loss) $ 3,215 $ (481 ) $ 435 $ (2,955 ) Net income (loss) attributable to non-controlling interest - 177 - (208 ) Net income (loss) attributable to ACM, basic and diluted $ 3,215 $ (658 ) $ 435 $ (2,747 ) Denominator: Weighted average shares outstanding, basic 15,838,540 5,086,989 15,611,863 4,927,973 Effect of dilutive securities 2,281,193 - 2,057,787 - Weighted average shares outstanding, diluted 18,119,733 5,086,989 17,669,650 4,927,973 Net income (loss) attributable to ACM per common share: Basic $ 0.20 $ (0.13 ) $ 0.03 $ (0.56 ) Diluted $ 0.18 $ (0.13 ) $ 0.02 $ (0.56 ) ACM has been authorized to issue Class A and Class B common stock since redomesticating in Delaware in November 2016. The two classes of common stock are substantially identical in all material respects, except for voting rights. Since ACM did not declare any dividends during the three and six months ended June 30, 2018 and 2017, the net income (loss) per common share attributable to each class is the same under the “two-class” method. As such, the two classes of common stock have been presented on a combined basis in the consolidated statements of operations and comprehensive income (loss) and in the above computation of net income (loss) per common share. Diluted net income (loss) per common share reflects the potential dilution from securities that could share in ACM’s earnings. ACM’s potential dilutive securities consist of convertible preferred stocks, warrants and stock options for the three and six months ended June 30, 2018 and 2017. Certain potential dilutive securities were excluded from the net income (loss) per share calculation because the impact would be anti-dilutive.

Revenue from contracts with customers is recognized using the following five steps pursuant to the New Revenue Standard: 1. Identify the contract(s) with a customer; 2. Identify the performance obligations in the contract; 3. Determine the transaction price; 4. Allocate the transaction price to the performance obligations in the contract; and 5. Recognize revenue when (or as) the entity satisfies a performance obligation. A contract contains a promise (or promises) to transfer goods or services to a customer. A performance obligation is a promise (or a group of promises) that is distinct. The transaction price is the amount of consideration a company expects to be entitled from a customer in exchange for providing the goods or services. The unit of account for revenue recognition is a performance obligation (a good or service). A contract may contain one or more performance obligations. Performance obligations are accounted for separately if they are distinct. A good or service is distinct if the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer, and the good or service is distinct in the context of the contract. Otherwise performance obligations are combined with other promised goods or services until the Company identifies a bundle of goods or services that is distinct. Promises in contracts which do not result in the transfer of a good or service are not performance obligations, as well as those promises that are administrative in nature, or are immaterial in the context of the contract. The Company has addressed whether various goods and services promised to the customer represent distinct performance obligations. The Company applied the guidance of ASC Topic 606-10-25-16 through 18 in order to verify which promises should be assessed for classification as distinct performance obligations. The Company’s contracts with customers include more than one performance obligation. For example, the delivery of a piece of equipment generally includes the promise to install the equipment in the customer’s facility. The Company’s performance obligations in connection with a sale of equipment generally include production, delivery and installation, together with the provision of a warranty. The transaction price is allocated to all the separate performance obligations in an arrangement. It reflects the amount of consideration to which the Company expects to be entitled in exchange for transferring goods or services, which may include an estimate of variable consideration to the extent that it is probable of not being subject to significant reversals in the future based on the Company’s experience with similar arrangements. The transaction price excludes amounts collected on behalf of third parties, such as sales taxes. This is done on a relative selling price basis using standalone selling prices (“SSP”). The SSP represents the price at which the Company would sell that good or service on a standalone basis at the inception of the contract. Given the requirement for establishing SSP for all performance obligations, if the SSP is directly observable through standalone sales, then such sales should be considered in the establishment of the SSP for the performance obligation. All of the Company’s products were sold in stand-alone arrangements, the Company does not have observable SSPs for most performance obligations as they are not regularly sold on a standalone basis. Production, delivery and installation of a product, together with provision of a warranty, are a single unit of accounting. Revenue is recognized when the Company satisfies each performance obligation by transferring control of the promised goods or services to the customer. Goods or services can transfer at a point in time (upon the acceptance of the products or upon the arrival at the destination as stipulated in the shipment terms) in a sale arrangement. In general, the Company recognizes revenue when a tool has been demonstrated to meet the customer’s predetermined specifications and is accepted by the customer. If terms of the sale provide for a lapsing customer acceptance period, the Company recognizes revenue as of the earlier of the expiration of the lapsing acceptance period and customer acceptance. In the following circumstances, however, the Company recognizes revenue upon shipment or delivery, when legal title to the tool is passed to a customer as follows: ● When the customer has previously accepted the same tool with the same specifications and the Company can objectively demonstrate that the tool meets all of the required acceptance criteria; ● When the sales contract or purchase order contains no acceptance agreement or lapsing acceptance provision and the Company can objectively demonstrate that the tool meets all of the required acceptance criteria; ● When the customer withholds acceptance due to issues unrelated to product performance, in which case revenue is recognized when the system is performing as intended and meets predetermined specifications; or ● When the Company’s sales arrangements do not include a general right of return. The Company offers post-warranty period services, which consist principally of the installation and replacement of parts and small-scale modifications to the equipment. The related revenue and costs of revenue are recognized when parts have been delivered and installed, risk of loss has passed to the customer, and collection is probable. The Company does not expect revenue from extended maintenance service contracts to represent a material portion of its revenue in the future. As such, the Company has concluded that its revenue recognition under the adoption of the New Revenue Standard will remain the same as previously reported and will not have material impacts to its condensed consolidated financial statements. The Company incurs costs related to the acquisition of its contracts with customers in the form of sales commissions. Sales commissions are paid to third party representatives and distributors. Contractual agreements with these parties outline commission structures and rates to be paid. Generally speaking, the contracts are all individual procurement decisions by the customers and are not for significant periods of time, nor do they include renewal provisions. As such, all contracts have an economic life of significantly less than a year. Accordingly, the Company expenses sales commissions when incurred in accordance with the practical expedient in the New Revenue Standard when the underlying contract asset is less than one year. These costs are recorded within sales and marketing expenses. Generally, all contracts have expected durations of one year or less. Accordingly, the Company applies the practical expedient allowed in the New Revenue Standard and does not disclose information about remaining performance obligations that have original expected durations of one year or less. The Company does not incur any costs to fulfill the contracts with customers that are not already reported in compliance with another applicable standard (for example, inventory or plant, property and equipment).

Income Taxes
Income Taxes | 6 Months Ended |

Income Tax Disclosure [Abstract] | |
Income Taxes | Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period during which such rates are enacted. The Company considers all available evidence to determine whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become realizable. Management considers the scheduled reversal of deferred tax liabilities (including the impact of available carryback and carry-forward periods), and projected taxable income in assessing the realizability of deferred tax assets. In making such judgments, significant weight is given to evidence that can be objectively verified. Based on all available evidence, in particular the Company’s three-year historical cumulative losses, recent operating results and U.S. pre-tax loss for the six months ended June 30, 2018, the Company recorded a valuation allowance against its U.S. net deferred tax assets. In order to fully realize the U.S. deferred tax assets, the Company will need to generate sufficient taxable income in future periods before the expiration of the deferred tax assets governed by the tax code. In each period since inception, the Company has recorded a valuation allowance for the full amount of net deferred tax assets in the United States, as the realization of deferred tax assets is uncertain. ACM Shanghai has shown a three-year historical cumulative profit and has projections of future income. As a result, the Company maintained a partial consolidated valuation allowance for the three and six months ended June 30, 2018 and December 31, 2017. The Company accounts for uncertain tax positions in accordance with the authoritative guidance on income taxes under which the Company may only recognize or continue to recognize tax positions that meet a "more likely than not" threshold. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as a component of the provision for income taxes. The Company’s effective tax rate differs from statutory rates of 21% for U.S. federal income tax purposes and 15% to 25% for Chinese income tax purposes due to the effects of the valuation allowance and certain permanent differences from book-tax differences. As a result, the Company recorded income tax expense of $164 and income tax benefit of $32 during the three months ended June 30, 2018 and 2017, respectively. For the six months ended June 30, 2018 and 2017, the Company recorded income tax expense of $186 and $749, respectively. As of June 30, 2018, the Company's total unrecognized tax benefits were approximately $44, which would not affect the effective tax rate if recognized. The Company will recognize interest and penalties, when they occur, related to uncertain tax provisions as a component of tax expense. No interest or penalties were recognized for the three and six months ended June 30, 2018. The Company files income tax returns in the United States, and state and foreign jurisdictions. The federal, state and foreign income tax returns are under the statute of limitations subject to tax examinations for the tax years ended December 31, 2009 through December 31, 2017. To the extent the Company has tax attribute carry-forwards, the tax years in which the attribute was generated may still be adjusted upon examination by the U.S. Internal Revenue Service, state or foreign tax authorities to the extent utilized in a future period. The Tax Cuts and Jobs Act (the “Tax Act”) enacted on December 22, 2017 introduced significant changes to U.S. income tax law. Effective January 1, 2018, the Tax Act reduced the U.S. statutory tax rate from 35% to 21% and created new taxes on certain foreign-sourced earnings and certain intercompany payments. Due to the timing of the enactment and the complexity involved in applying the provisions of the Tax Act, the Company made reasonable estimates of the effects and recorded provisional amounts in its financial statements as of December 31, 2017. As the Company collects and prepares necessary data, and interprets the Tax Act and any additional guidance issued by the U.S. Treasury Department, the U.S. Internal Revenue Service and other standard-setting bodies, the Company may make adjustments to the provisional amounts. Those adjustments may materially affect the Company’s provision for income taxes and effective tax rate in the period in which the adjustments are made. There were no adjustments made in the three and six months ended June 30, 2018. The accounting for the tax effects of the Tax Act will be completed later in 2018. |

Accounting Policies [Abstract] | |
Basis of Presentation and Principles of Consolidation | The consolidated accounts include ACM and its subsidiaries, ACM Shanghai, ACM Wuxi, CleanChip and ACM Korea. Subsidiaries are those entities in which ACM, directly and indirectly, controls more than one half of the voting power. All significant intercompany transactions and balances have been eliminated upon consolidation. The accompanying condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and the rules and regulations of the Securities and Exchange Commission (“SEC”) for reporting on Form 10-Q. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements herein. The unaudited condensed consolidated financial statements herein should be read in conjunction with the historical consolidated financial statements of the Company for the year ended December 31, 2017 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. The accompanying condensed consolidated balance sheet as of June 30, 2018, the condensed consolidated statements of operations and comprehensive income (loss) for the three and six months ended June 30, 2018 and 2017, and the condensed consolidated statements of cash flows for the six months ended June 30, 2018 and 2017 are unaudited. In the opinion of management, the unaudited condensed consolidated financial statements of the Company reflect all adjustments that are necessary for a fair presentation of the Company’s financial position and results of operations. Such adjustments are of a normal recurring nature, unless otherwise noted. The balance sheet as of June 30, 2018 and the results of operations for the three months and six months ended June 30, 2018 are not necessarily indicative of the results to be expected for any future period. |
Use of Estimates | The preparation of condensed consolidated financial statements in conformity with 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 balance sheet date and the reported revenues and expenses during the reported period in the condensed consolidated financial statements and accompanying notes. The Company’s significant accounting estimates and assumptions include, but are not limited to, those used for the valuation and recognition of stock-based compensation arrangements and warrant liability, realization of deferred tax assets, assessment for impairment of long-lived assets, allowance for doubtful accounts, inventory valuation for excess and obsolete inventories, lower of cost and market value or net realizable value of inventories, depreciable lives of property and equipment, and useful life of intangible assets.

Basic and Diluted Net Income (Loss) attributable to ACM per Common Share | Basic and diluted net income (loss) attributable to ACM per common share is calculated as follows: Three Months Ended June 30, Six Months Ended June 30, 2018 2017 2018 2017 Numerator: Net income (loss) $ 3,215 $ (481 ) $ 435 $ (2,955 ) Net income (loss) attributable to non-controlling interest - 177 - (208 ) Net income (loss) attributable to ACM, basic and diluted $ 3,215 $ (658 ) $ 435 $ (2,747 ) Denominator: Weighted average shares outstanding, basic 15,838,540 5,086,989 15,611,863 4,927,973 Effect of dilutive securities 2,281,193 - 2,057,787 - Weighted average shares outstanding, diluted 18,119,733 5,086,989 17,669,650 4,927,973 Net income (loss) attributable to ACM per common share: Basic $ 0.20 $ (0.13 ) $ 0.03 $ (0.56 ) Diluted $ 0.18 $ (0.13 ) $ 0.02 $ (0.56 ) ACM has been authorized to issue Class A and Class B common stock since redomesticating in Delaware in November 2016. The two classes of common stock are substantially identical in all material respects, except for voting rights. Since ACM did not declare any dividends during the three and six months ended June 30, 2018 and 2017, the net income (loss) per common share attributable to each class is the same under the “two-class” method. As such, the two classes of common stock have been presented on a combined basis in the consolidated statements of operations and comprehensive income (loss) and in the above computation of net income (loss) per common share. Diluted net income (loss) per common share reflects the potential dilution from securities that could share in ACM’s earnings. ACM’s potential dilutive securities consist of convertible preferred stocks, warrants and stock options for the three and six months ended June 30, 2018 and 2017. Certain potential dilutive securities were excluded from the net income (loss) per share calculation because the impact would be anti-dilutive. |

Revenue from contracts with customers is recognized using the following five steps pursuant to the New Revenue Standard: 1. Identify the contract(s) with a customer; 2. Identify the performance obligations in the contract; 3. Determine the transaction price; 4. Allocate the transaction price to the performance obligations in the contract; and 5. Recognize revenue when (or as) the entity satisfies a performance obligation. A contract contains a promise (or promises) to transfer goods or services to a customer. A performance obligation is a promise (or a group of promises) that is distinct. The transaction price is the amount of consideration a company expects to be entitled from a customer in exchange for providing the goods or services. The unit of account for revenue recognition is a performance obligation (a good or service). A contract may contain one or more performance obligations. Performance obligations are accounted for separately if they are distinct. A good or service is distinct if the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer, and the good or service is distinct in the context of the contract. Otherwise performance obligations are combined with other promised goods or services until the Company identifies a bundle of goods or services that is distinct. Promises in contracts which do not result in the transfer of a good or service are not performance obligations, as well as those promises that are administrative in nature, or are immaterial in the context of the contract. The Company has addressed whether various goods and services promised to the customer represent distinct performance obligations. The Company applied the guidance of ASC Topic 606-10-25-16 through 18 in order to verify which promises should be assessed for classification as distinct performance obligations. The Company’s contracts with customers include more than one performance obligation. For example, the delivery of a piece of equipment generally includes the promise to install the equipment in the customer’s facility. The Company’s performance obligations in connection with a sale of equipment generally include production, delivery and installation, together with the provision of a warranty. The transaction price is allocated to all the separate performance obligations in an arrangement. It reflects the amount of consideration to which the Company expects to be entitled in exchange for transferring goods or services, which may include an estimate of variable consideration to the extent that it is probable of not being subject to significant reversals in the future based on the Company’s experience with similar arrangements. The transaction price excludes amounts collected on behalf of third parties, such as sales taxes. This is done on a relative selling price basis using standalone selling prices (“SSP”). The SSP represents the price at which the Company would sell that good or service on a standalone basis at the inception of the contract. Given the requirement for establishing SSP for all performance obligations, if the SSP is directly observable through standalone sales, then such sales should be considered in the establishment of the SSP for the performance obligation. All of the Company’s products were sold in stand-alone arrangements, the Company does not have observable SSPs for most performance obligations as they are not regularly sold on a standalone basis. Production, delivery and installation of a product, together with provision of a warranty, are a single unit of accounting. Revenue is recognized when the Company satisfies each performance obligation by transferring control of the promised goods or services to the customer. Goods or services can transfer at a point in time (upon the acceptance of the products or upon the arrival at the destination as stipulated in the shipment terms) in a sale arrangement. In general, the Company recognizes revenue when a tool has been demonstrated to meet the customer’s predetermined specifications and is accepted by the customer. If terms of the sale provide for a lapsing customer acceptance period, the Company recognizes revenue as of the earlier of the expiration of the lapsing acceptance period and customer acceptance. In the following circumstances, however, the Company recognizes revenue upon shipment or delivery, when legal title to the tool is passed to a customer as follows: ● When the customer has previously accepted the same tool with the same specifications and the Company can objectively demonstrate that the tool meets all of the required acceptance criteria; ● When the sales contract or purchase order contains no acceptance agreement or lapsing acceptance provision and the Company can objectively demonstrate that the tool meets all of the required acceptance criteria; ● When the customer withholds acceptance due to issues unrelated to product performance, in which case revenue is recognized when the system is performing as intended and meets predetermined specifications; or ● When the Company’s sales arrangements do not include a general right of return. The Company offers post-warranty period services, which consist principally of the installation and replacement of parts and small-scale modifications to the equipment. The related revenue and costs of revenue are recognized when parts have been delivered and installed, risk of loss has passed to the customer, and collection is probable. The Company does not expect revenue from extended maintenance service contracts to represent a material portion of its revenue in the future. As such, the Company has concluded that its revenue recognition under the adoption of the New Revenue Standard will remain the same as previously reported and will not have material impacts to its condensed consolidated financial statements. The Company incurs costs related to the acquisition of its contracts with customers in the form of sales commissions. Sales commissions are paid to third party representatives and distributors. Contractual agreements with these parties outline commission structures and rates to be paid. Generally speaking, the contracts are all individual procurement decisions by the customers and are not for significant periods of time, nor do they include renewal provisions. As such, all contracts have an economic life of significantly less than a year. Accordingly, the Company expenses sales commissions when incurred in accordance with the practical expedient in the New Revenue Standard when the underlying contract asset is less than one year. These costs are recorded within sales and marketing expenses. Generally, all contracts have expected durations of one year or less. Accordingly, the Company applies the practical expedient allowed in the New Revenue Standard and does not disclose information about remaining performance obligations that have original expected durations of one year or less. The Company does not incur any costs to fulfill the contracts with customers that are not already reported in compliance with another applicable standard (for example, inventory or plant, property and equipment).
