EXPLANATORY NOTE
Exterran Corporation (together with its subsidiaries, the “Company,” “Exterran Corporation,” “our,” “we” or “us”) is filing this Amendment No. 1 (this “Form 10-K/A”) to amend its Annual Report on Form 10-K for the year ended December 31, 2015, originally filed with the Securities and Exchange Commission (the “SEC”) on February 26, 2016 (the “Original Filing”), to restate its Consolidated and Combined Financial Statements included in Part IV, Item 15 (collectively referred to as “Financial Statements”) and related footnote disclosures as of December 31, 2015 and 2014 and for the years ended December 31, 2015, 2014 and 2013 (including the unaudited quarterly periods within 2015 and 2014). In addition, this Form 10-K/A also includes under Part II, Item 6 restated selected combined statement of operations data and other financial data for the years ended December 31, 2012 and 2011 and restated selected combined balance sheet data as of December 31, 2013, 2012 and 2011. This Form 10-K/A also amends certain other items in the Original Filing, as listed in “Items Amended in This Filing” below.

Background and Effects of Restatement

Subsequent to the filing of the Original Filing, senior management of the Company identified errors relating to the application of percentage-of-completion accounting principles to certain business lines of our subsidiary, Belleli Energy S.r.l. (subsequently renamed Exterran Italy S.r.l.). Such business lines comprise engineering, procurement and construction for the manufacture of tanks for tank farms and the manufacture of evaporators and brine heaters for desalination plants in the Middle East (referred to as “Belleli EPC” or the “Belleli EPC business” herein). Belleli Energy S.r.l. is headquartered in Mantova, Italy, and its operations are based in Dubai, United Arab Emirates. Management promptly reported the matter to the Audit Committee of the Company’s Board of Directors, which immediately retained counsel, who in turn retained a forensic accounting firm, to initiate an internal investigation. As previously disclosed in the Company’s Current Report on Form 8-K filed with the SEC on April 26, 2016, the Company’s management and the Audit Committee of the Board of Directors determined, based on the preliminary results of the internal investigation, that the Financial Statements and related report of independent registered public accounting firm within the Original Filing should no longer be relied upon as a result of errors, and possible irregularities, relating to the accounting for certain Belleli EPC projects.

As a result of the internal investigation, management identified inaccuracies related to Belleli EPC projects within our product sales segment in estimating the total costs required to complete projects impacting the years ended December 31, 2015, 2014, 2013, 2012 and 2011 (including the unaudited quarterly periods within 2015 and 2014). The application of percentage-of-completion accounting principles on Belleli EPC projects is estimated using the cost to total cost basis, which requires an estimate of total costs (labor and materials) required to complete each project. The cost-to-complete estimates for Belleli EPC projects were incorrectly estimated and at times manipulated by or at the direction of certain former members of Belleli EPC local senior management, resulting in a misstatement of product sales revenue. The inaccurate cost-to-complete estimates for some Belleli EPC projects also resulted in the need to establish and/or increase contract loss provisions for certain projects, and as a result, product sales cost of sales was misstated. Additionally, penalties for liquidated damages on certain projects were not correctly estimated. Furthermore, other errors within product sales cost of sales on Belleli EPC projects were identified, primarily relating to vendor claims, customer warranties and costs being charged to incorrect projects. As a result of the errors and conduct identified, our product sales revenue was overstated by $19.3 million, $28.1 million, $5.7 million, $1.2 million and $10.1 million during the years ended December 31, 2015, 2014, 2013, 2012 and 2011, respectively, and our product sales cost of sales was understated by $0.4 million, $9.5 million and $21.0 million during the years ended December 31, 2015, 2014 and 2013, respectively, and overstated by $3.1 million and $3.5 million during the years ended December 31, 2012 and 2011, respectively. These errors and inaccuracies also resulted in the misstatement of accounts receivable, costs and estimated earnings in excess of billings on uncompleted contracts, billings on uncompleted contracts in excess of costs and estimated earnings, accrued liabilities and related income tax effects for each of the periods impacted.

We separately identified prior period errors related to the miscalculation and recovery of non-income-based tax receivables owed to us from the Brazilian government as of December 31, 2011. As a result of these errors and since relevant prior periods were being restated, we recorded adjustments to decrease intangible and other assets, net, beginning parent equity and other income by approximately $26.1 million, $17.5 million and $10.7 million, respectively, as of and for the year ended December 31, 2011 and increase other comprehensive income by approximately $2.1 million as of December 31, 2011. These errors also resulted in the misstatement of intangible and other assets, net, other (income) expense, net, and accumulated other comprehensive income in periods subsequent to December 31, 2011.

Along with restating our Financial Statements to correct the errors discussed above, we recorded adjustments for certain immaterial accounting errors related to the periods covered in this Form 10-K/A.



Table of Contents


Contemporaneously with filing the Form 8-K on April 26, 2016, we self-reported the errors and possible irregularities at Belleli EPC to the SEC. Since then, we have been cooperating with the SEC in its investigation of this matter, including responding to a subpoena for documents related to the restatement and compliance with the U.S. Foreign Corrupt Practices Act (“FCPA”), which are also being provided to the Department of Justice at its request. The FCPA related requests in the SEC subpoena pertain to our policies and procedures, information about our third-party sales agents, and documents related to historical internal investigations completed prior to November 2015.

For a summary of the effect of the restatement as of December 31, 2015 and 2014 and for the years ended December 31, 2015, 2014 and 2013, see Note 3 and Note 23 (Quarterly Results) to the Financial Statements in this Form 10-K/A. Additionally, see Part II, Item 6 in this Form 10-K/A for a summary of the effect of the restatement on selected combined statement of operations data and other financial data for the years ended December 31, 2012 and 2011 and selected combined balance sheet data as of December 31, 2013, 2012 and 2011.

Internal Control Consideration

The Original Filing did not include a report of management’s assessment regarding internal control over financial reporting or an attestation report of the Company’s independent registered accounting firm due to a transition period established by rules of the SEC for newly public companies. However, in connection with the restatement in this Form 10-K/A, management evaluated the effectiveness of our internal control over financial reporting as of December 31, 2015, and concluded that deficiencies in the design and operating effectiveness of our internal controls, collectively, represent material weaknesses in our internal control over financial reporting and, therefore, that we did not maintain effective internal control over financial reporting as of December 31, 2015. For a description of the material weaknesses identified by management and management’s implemented and planned remediations for those material weaknesses, see “Part II, Item 9A — Controls and Procedures.”

Items Amended in This Filing

For the convenience of the reader, this Form 10-K/A sets forth the Original Filing, in its entirety, as amended to reflect the restatement. No attempt has been made in this Form 10-K/A to update other disclosures presented in the Original Filing of our Annual Report on Form 10-K for the year ended December 31, 2015, except as required to reflect the effects of the restatement. The financial statements contained in the Form 10-K were derived from the audited combined financial statements contained in our Registration Statement on Form 10, as amended, initially filed with the Securities and Exchange Commission on March 13, 2015 and declared effective on October 21, 2015 (“Registration Statement”), filed as part of the Company’s Spin-off from Archrock, Inc. (named Exterran Holdings, Inc. prior to November 3, 2015) (“Archrock”), and the Registration Statement contains substantially the same financial statement errors as those contained on the Original Filing. Accordingly, this Form 10-K/A should be read in conjunction with Exterran Corporation’s filings made with the SEC subsequent to the filing of the Form 10-K. The following items have been amended as a result of this restatement:

Part I — Disclosure Regarding Forward-Looking Statements

Part I, Item 1 — Business

Part I, Item 1A — Risk Factors
Part I, Item 3 — Legal Proceedings

Part II, Item 6 — Selected Financial Data

Part I, Item 7A — Quantitative and Qualitative Disclosures About Market Risk

Part II, Item 9A — Controls and Procedures

Spin-off

On November 3, 2015, Archrock, Inc. (named Exterran Holdings, Inc. prior to November 3, 2015) (“Archrock”) completed the spin-off (the “Spin-off”) of its international contract operations, international aftermarket services (the international contract operations and international aftermarket services businesses combined are referred to as the “international services businesses” and include such activities conducted outside of the United States of America (“U.S.”)) and global fabrication businesses into an independent, publicly traded company named Exterran Corporation. We refer to the global fabrication business previously operated by Archrock as our product sales business. To effect the Spin-off, on November 3, 2015, Archrock distributed, on a pro rata basis, all of our shares of common stock to its stockholders of record as of October 27, 2015 (the “Record Date”).

General

We provide our products and services to a global customer base consisting of companies engaged in all aspects of the oil and natural gas industry, including large integrated oil and natural gas companies, national oil and natural gas companies, independent oil and natural gas producers and oil and natural gas processors, gatherers and pipeline operators. We operate in three primary business lines: contract operations, aftermarket services and product sales.

In The nature and inherent interactions between and among our contract operations business which accounted for approximately 25% of our revenue and 63% of our gross margin in 2015, we own and operate natural gas compression equipment and crude oil and natural gas production and processing equipment on behalf of our customers outside of the U.S. These services can include engineering, design, procurement, on-site construction and operation of natural gas compression and crude oil or natural gas production and processing facilities for our customers. Our contract operations business is underpinned by long-term commercial contracts with large customers, including several national oil and natural gas companies, which we believe provide us with relatively stable cash flows due to our exposure to the production phase of oil and gas development, compared to drilling and completion related energy services and product providers. We believe our contract operations services generally allow our customers that outsource their compression or production and processing needs to achieve higher production rates than they would achieve with their own operations, resulting in increased revenue for our customers. In addition, outsourcing allows our customers flexibility for their compression and production and processing needs while limiting their capital requirements. These contracts generally involve initial terms ranging from three to five years, and in some cases can be in excess of 10 years. In many instances, we are able to renew those contracts prior to the expiration of the initial term; in some cases, we may sell the underlying assets to our customers pursuant to purchase options or otherwise.

In our aftermarket services business, which accounted for approximately 7% of our revenue and 8% of our gross margin in 2015, we provide operations, maintenance, overhaul and reconfiguration services outside of the U.S. to support our customers who own their own compression, production, processing, treating and related equipment. Our services range from routine maintenance services and parts sales to the full operation and maintenance of customer-owned assets. We seek to couple our aftermarket services with our product sales business to provide ongoing services to customers who buy equipment from us and to sell those services to customers who have bought equipment from other companies.

In our product sales business, which accounted for approximately 68% of our revenue and 29% of our gross margin in 2015, we design, engineer, manufacture, install and sell natural gas compression packages as well as equipment used in the production, treating and processing of crude oil and natural gas to customers both in the U.S. and internationally. Additionally, we design, engineer, manufacture and install this equipment for use in our contract operations business. Our product sales business line also provides engineering, procurement and manufacturing services related to the manufacture of critical process equipment for refinery and petrochemical facilities, the manufacture of tanks for tank farms and the manufacture of evaporators and brine heaters for desalination plants. Furthermore, we combine our products into an integrated solution that we design, engineer, procure and, in certain cases, construct on-site for sale to our customers. We believe the expansive range of products we sell through our global platform enables us to take advantage of the ongoing, worldwide energy infrastructure build-out.

Competitive Strengths

We believe the following key competitive strengths will allow us to create shareholder value:

Global platform and expansive service and product offerings poised to capitalize on the global energy infrastructure build-out.  Despite the recent decline in oil and natural gas prices and the impact on demand for our services and products, we expect that global oil and natural gas infrastructure will continue to be built out andlines provide us with opportunities for growth, as we believe our global customer base will continue to invest in infrastructure projects based on longer-term fundamentals that are less tied to near-term commodity prices. We believe our size, geographic scope and broad customer base provide us with a unique advantage in meeting our customers’ needs, particularly with regard to large-scale project construction and development, and will allow us to capture future growth opportunities. We provide our customers a broad variety of products and services in approximately 30 countries worldwide, including outsourced compression, production and processing services, as well as the sale of a large portfolio of natural gas compression and oil and natural gas production and processing equipment and installation services. We believe our contract operations services generally allow our customers that outsource their compressioncross-sell or production and processing needs to achieve higher production rates than they would achieve with their own operations, resulting in increased revenue for our customers. In addition, outsourcing allows our customers flexibility for their compression and production and processing needs while limiting their capital requirements. By offering a broad range of services and products that leverage our core strengths, we believe we provide uniqueoffer integrated solutions that meet our customers’ needs. We believe the breadth and quality of our products and services, the depth of our customer relationships and our presence in many major oil and natural gas-producing regions place us in a position to capture additional business on a global basis.

High-quality products and services.  We have built a network of high-quality energy infrastructure assets that are strategically deployed across our global platform. Through our history of operating a wide variety of products in many energy-producing markets around the world, we have developed the technical expertise and experience required to understand the needs of our customers and meet those needs through a range of products and services. These products and services include highly customized compression, production and processing solutions as well as standard products based on our expertise, in support of a range of projects, from those requiring quick completion to those that may take several years to fully develop. Additionally, our experience has allowed us to develop efficient systems and processes and a skilled workforce that allow us to provide high-quality services throughout international markets. We utilize this technical expertise and long history of developing and operating projects for our customers to continually improve our products and services, which enables us to provide our customers with high-quality, comprehensive oil and natural gas infrastructure support worldwide.

Complementary businesses enable us to offer customers integrated infrastructure solutions.  We aim to provide our customers with a single source to meet their energy infrastructure needs, and we believe we have the ability to serve our customers’ changing needs in a variety of ways. For customers that seek to limit capital spending on energy infrastructure projects, we offer our full operations services through our contract operations business. Alternatively, for customers that prefer to develop and acquire their own infrastructure assets, we are able to sell equipment and facilities for their operations. In addition, in those cases, we can also provide operations, maintenance, overhaul and reconfiguration services following the sale through our aftermarket services business. We also provide aftermarket services to customers that own compression, production, processing and treating equipment that was not purchased from us. Furthermore, we combine our products into an integrated solution that we design, engineer, procure and, in certain cases, construct on-site for sale to our customers. Because of the breadth of our products and our ability to deliver those products through our different delivery models, we believe we are able to provide the solution that is most suitable to our customers in the markets in which they operate. We believe this ability to provide our customers with a variety of products and services provides us with greater stability, as we are able to adjust the products and services we provide to reflect our customers’ changing needs.

Cash flows from contract operations business supported by long-term contracts with diverse customer base.  We provide contract operations services to customers located in approximately 15 countries. Within our contract operations business, we seek to enter into long-term contracts with a diverse collection of customers, including large integrated oil and natural gas companies and national energy companies. These contracts generally involve initial terms ranging from three to five years, and in some cases can be in excess of 10 years, and typically require our customers to pay our monthly service fee even during periods of limited or disrupted natural gas flows. In addition, our large, international customer base provides a diversified revenue stream, which we believe reduces customer and geographic concentration risk. Furthermore, our customer base includes several companies that are among the largest and most well-known companies within their respective regions throughout our global platform.

Experienced management team.  We have an experienced and skilled management team with a long track record of driving growth through organic expansion and selective acquisitions. The members of our management team have strong relationships in the oil and gas industry and have operated through numerous commodity price cycles throughout our areas of operations. Members of our management team have spent a significant portion of their respective careers at highly regarded energy and manufacturing companies and have accumulated an average of over 25 years of industry experience.

Well-balanced capital structure with sufficient liquidity.  We intend to maintain a capital structure with an appropriate amount of leverage and the financial flexibility to invest in our operations and pursue attractive growth opportunities that we believe will increase the overall earnings and cash flow generated by our business. At December 31, 2015, taking into account guarantees through letters of credit, we had undrawn and available capacity of $278.6 million under our revolving credit facility. In addition, as of December 31, 2015, we had $29.0 million of cash and cash equivalents on hand.

Business Strategies

We intend to continue to capitalize on our competitive strengths to meet our customers’ needs through the following key strategies:

Strategically grow our business to generate attractive returns to our shareholders.  Our primary strategic focus involves the growth of our business through expanding our product and services offerings and growing our customer base, as well as targeting redevelopment opportunities in the U.S. energy market and expansions into new international markets benefiting from the global energy infrastructure build-out. Our diverse product and service portfolio allows ussolutions to readily respond to changes in industry and economic conditions. We believe our global footprint allows us to provide the prompt product availability our customers require, and we can construct projects in new locations as needed to meet customer demand. We have the ability to readily deploy our capital to construct new or supplemental projects that we build, own and operate on behalf of our customers through our contract operations business. In addition, we seek to provide our customers with integrated infrastructure solutions by combining product and service offerings across our businesses. We plan to supplement our organic growth with select acquisitions in key markets to further enhance our geographic reach, product offerings and other capabilities. We believe acquisitions of this nature will allow us to generate incremental revenues from existing and new customers and obtain greater market share.
customers.

Expand customer base and deepen relationships with existing customers.  We believe the uniquely broad range of services we offer, the quality of our products and services and our diverse geographic footprint position us well to attract new customers and cross-sell our products and services to existing customers. In addition, we have a long history of providing our products and services to our customers, which we couple with the technical expertise of our experienced engineering personnel to understand and meet our customers’ needs, particularly as those needs develop and change over time. We intend to devote significant business development resources to market our products and services, leverage existing relationships and expedite our growth potential. We also seek to provide supplemental projects and services to our customers as their needs evolve over time. Finally, we expect to be able to offer certain of our products, including manufactured compressors, to prospective customers that are competitors of Archrock, which increases our prospective customer base and provides us with the opportunity to diversify our revenue sources.

Continue our industry-leading safety performance.  Because of our emphasis on training and safety protocols for our employees, we have delivered industry-leading safety performance, which has resulted in our achieving a strong reputation for safety. We believe our safety performance and reputation help us to attract and retain customers and employees. We have adopted rigorous processes and procedures to facilitate our compliance with safety regulations and policies. We work diligently to meet or exceed applicable safety regulations, and we intend to continue to focus on our safety monitoring function as our business grows and operating conditions change.

Continue to optimize our global platform, products and services and enhance our profitability.  We regularly review and evaluate the quality of our operations, products and services. This process includes customer review programs to assess the quality of our performance. In addition, we intend to use our global platform to reach a wide variety of customers, which we believe can enable us to achieve cost savings in our operations. We believe our ongoing focus on improving the quality of our operations, products and services results in greater satisfaction among our customers, which we believe results in greater profitability and value for our shareholders.

Contract Operations

In our contract operations business, we own and operate natural gas compression equipment and crude oil and natural gas production and processing equipment on behalf of our customers outside of the U.S. We provide comprehensive contract operations services to our customers outside of the U.S. based on each customer’s needs and operating specifications. TheseOur services include the provision of the personnel, equipment, tools, materials and supplies to meet our customers’ natural gas compression or oil orand natural gas production orand processing service needs. Activities we may perform in meeting our customer’s needs as well asinclude engineering, designing, sourcing, owning,constructing, installing, operating, servicing, repairing, maintaining and maintainingdecommissioning equipment owned by us necessary to provide these services.

We generally enter into contracts with our contract operations customers with initial terms ranging between three to five years, and in some cases, can be in excess of 10 years. In many instances, we are able to renew those contracts prior to the expiration of the initial term and in other instances, we may sell the underlying assets to our customers pursuant to purchase options or negotiated sale. If a contract is not renewed or a customer does not purchase the underlying assets, our equipment is returned to our premises for future redeployment. These contracts canmay require us to provide complete engineering, design and installation services and amake significant investmentinvestments in equipment, facilities and related installation costs. These projects may include several compressor units on one site or entire facilities designed to process and treat oil or natural gas to make it suitable for end use. Our customerscommercial contracts generally are requiredrequire customers to pay a monthly service fee even during periods of limited or disrupted oil or natural gas flows, which enhances the stabilitywe believe provide us with relatively stable and predictability of ourpredictable cash flows. Additionally, because we typically do not take title to the oil or natural gas we compress, process or treat, and because the natural gas we use as fuel for our compressors and other equipment is supplied by our customers, we have limited direct exposure to short-term commodity price fluctuations.

Our equipment is maintained in accordance with established maintenance schedules. These maintenance procedures are updated as technology changes and as our operations team develops new techniques and procedures. In addition, because our field technicians provide maintenance on our contract operations equipment, they are familiar with the condition of our equipment and can readily identify potential problems. In our experience, these maintenance procedures maximize equipment life and unit availability, minimize avoidable downtime and lower the overall maintenance expenditures over the equipment life. We believe our contract operations services generally allow our customers to achieve higher production rates than they would achieve with their own operations, resulting in increased revenue for our customers. In addition, outsourcing these services allows our customers flexibility for their compression and production and processing needs while limiting their capital requirements.

During the year ended December 31, 2015,2017, approximately 25%31% of our revenue and 63%70% of our gross margin was generated from contract operations. Our contract operations business is capital intensive. As of December 31, 2015,2017, the net book value of property, plant and equipment associated with our contract operations business provided contract operations services using a fleet of 901 natural gas compression units with an aggregate capacity of approximately 1,181,000 horsepower and a fleet of production and processing equipment.

We believe that our aftermarket services and product sales businesses, described below, provide opportunities to cross-sell our contract operations services.was $745.9 million.

Aftermarket Services

Our services range from routine maintenance services and parts sales to the full operation and maintenance of customer-owned equipment.

We generally enter into contracts with our operation and maintenance customers with initial terms ranging between two to four years, and in some cases, in excess of six years. In many instances, we are able to renew those contracts prior to the expiration of the initial term. We believe that we are particularly well qualified to provide these services because of our highly experienced operating personnel and technical and engineering expertise.expertise gained through providing similar services as part of our contract operations business. In addition, our aftermarket services business is a component ofcompliments our abilitystrategy to provide integrated infrastructure solutions to our customers because it enables us to continue to serve our customers after the sale of any assets or facilities manufactured through our product sales business. As a result, weWe seek to couple our aftermarket services with our product sales business to provide ongoing services to customers who buy equipment from us and also seek to sell those services to customers who have bought equipment from other businesses to maintain and develop our relationships with our customers.companies.

During the year ended December 31, 2015,2017, approximately 7%9% of our revenue and 8% of our gross margin was generated from aftermarket services.

Industry Overview

Natural Gas Compression

TheOur international compression business is comprised primarily of large horsepower compressors that are typically deployed in facilities comprised of several compressors on one site. A significant portion of this business involves comprehensive projects that require the design, engineering, manufacture, delivery and installation of several compressors on one site alongcoupled with related natural gas treatmenttreating and processing equipment. We are able to serve our customers’ needs for such projects through our product sales business and with follow-on services from our aftermarket services business, or through the provision of our contract operations services.

Natural gas compression is a mechanical process whereby the pressure of a given volume of natural gas is increased to a desired higher pressure for transportation from one point to another and is essential to the production and transportation of natural gas. Compression is typically required several times during the natural gas production and transportation cycle, including (i) at the wellhead, (ii) throughout gathering and distribution systems, (iii) into and out of processing and storage facilities and (iv) along pipelines. Natural gas compression can also be used to re-inject associated gas into producing wells to provide enhanced oil recovery.

Production and Processing

Crude oil and natural gas are generally not marketable as produced at the wellhead and must be processed or treated before they can be transported to market. Production and processing equipment is used to separate and treat oil and natural gas as they are produced to achieve a marketable quality of product. Production processing typically involves the separation of oil and natural gas and the removal of contaminants.contaminants or the separation of marketable liquids from the gas stream prior to transportation. The end result is “pipeline” or “sales” quality oil and natural gas. Further processing or refining is almost always required before oil or natural gas is suitable for use as fuel or feedstock for petrochemical production. Production processing normally takes place in the “upstream” and “midstream” segments, while refining and petrochemical processing is referred to as the “downstream” segment. Wellhead or upstream production and processing equipment include a wide and diverse range of products.

Table of Contents



We manufacture and stock standard production equipment based on historical product mix and expected customer purchases following general trends of oil and natural gas production. In addition, we sell custom-engineered, built-to-specification production and processing equipment. We also provide integrated solutions comprised of a combination of our products into a single offering, which typically consists of much larger equipment packages than standard equipment and is generally used in much larger scale production operations. The custom equipment segment is primarily driven by global economic trends, and the specifications for purchased equipment can vary significantly. Technology, engineering capabilities, project management, available manufacturing space and quality control standards are the key drivers in the custom equipment segment.

Outsourcing

Natural gas producers, transporters and processors choose to outsource their operations due to the benefits and flexibility of contract operations. WeIn particular, we believe outsourcing compression, production and processing operations to service providers such as us offers customers:

access to the service provider’sour specialized personnel and technical skills, including engineers and field service and maintenance employees, which we believe generally leads to improved production rates and/orand increased throughput and higher revenues;

the ability to increase their profitability by transporting or producing a higher volume of natural gas through decreased equipment downtime and reduced operating, maintenance and equipment costs by allowing us, as the service provider, to efficiently manage their operations; and

the flexibility to deploy their capital on projects more directly related to their primary business by reducing their investment in compression, production and processing equipment and related maintenance capital requirements.

Oil and Natural Gas Industry Cyclicality Volatility and SeasonalityVolatility

Changes in oil and natural gas exploration and production spending normally result in changes in demand for our products and services. However, we believe our contract operations business is typically less impacted by commodity prices than certain other energy service products and services because compression, production and processing services are necessary for oil and natural gas to be delivered from the wellhead to end users. Furthermore, our contract operations business is tied primarily to oil and natural gas production and consumption, which are generally less cyclical in nature than exploration activities.

Demand for oil and natural gas is cyclical and subject to fluctuations. This is primarily because the industry is driven by commodity demand and corresponding price movements. When oil and natural gas price increases occur, producers typically increase their capital expenditures, which generally results in greater activity levels and revenues for equipment providers to the oil and gas industry. During periods of lower oil or natural gas prices, producers typically decrease their capital expenditures, which generally results in lower activity levels and revenues for equipment providers to the oil and gas industry.

Seasonal Fluctuations

Our results of operations have not historically reflected any material seasonal tendencies and we currently do not believe that seasonal fluctuations will have a material impact on us in the foreseeable future.

Markets, Customers and Competition

Our global customer base consists primarily of companies engaged in all aspects of the oil and natural gas industry, including large integrated oil and natural gas companies, national energy companies, independent producers and natural gas processors, gatherers and pipeline operators.

During the years ended December 31, 20152017 and 2014,2015, Archrock and Archrock Partnersits affiliates accounted for approximately 12% and 11% of our total revenues. We expect to continue providing Archrock and Archrock Partners with certain manufactured products, including compressors, and we will depend on themrevenue, respectively. During the year ended December 31, 2016, Petroleo Brasileiro S.A. (“Petrobras”) accounted for a significant amountapproximately 10% of our product salestotal revenue. No other customer accounted for more than 10% of our revenue in 2017, 2016 and 2015.

We currently operate in approximately 30 countries. We have product salesmanufacturing facilities in the U.S., Europe, AsiaSingapore and the Middle East.United Arab Emirates and offices in the major oil and gas regions around the world.

The businesses in which we operate are highly competitive. Overall, we experience considerable competition from companies that may be able to more quickly adapt to changes within our industry and changes in economic conditions as a whole and to more readily take advantage of available opportunities. We believe we are competitive with respect to price, equipment availability, customer service, flexibility in meeting customer needs, technical expertise, quality and reliability of our compression, production and processing equipment and related services. We face vigorous competition throughout our businesses, with some firms competing with us in multiple businesses. In our product sales business, we have different competitors in the standard and custom-engineered equipment segments. Competitors in the standard equipment segment include several large companies and a large number of small, regional fabricators. Our competition in the custom-engineered segment consists mainly of larger companies with the ability to provide integrated projects and product support after the sale. The ability to manufacture large custom-engineered systems near the point of end-use is often a competitive advantage.

We expect to face increased competition as we seek to diversify our customer base and increase utilization of our service offerings.

We also expect to be able to offer certain of our products, including manufactured compressors, to prospective customers that were previously competitors of Archrock, which increases our prospective customer base and ability to diversify our revenue sources. In addition, in connection with the completion of the Spin-off, we entered into a supply agreement pursuant to which we provide Archrock and Archrock Partners with manufactured equipment.

The separation and distribution agreement from the Spin-off contains certain noncompetition provisions addressing restrictions for a limited period of time after the Spin-off on our ability to provide compression contract operations and aftermarket services in the U.S. and on Archrock’s ability to provide compression contract operations and aftermarket services outside of the U.S. and product sales to customers worldwide that expire on November 3, 2018, subject to certain exceptions.

Sources and Availability of Raw Materials

We manufacture natural gas compression and oil and natural gas production and processing equipment to provide contract operations services and to sell to third parties from components which we acquire from a wide range of vendors. These components represent a significant portion of the cost of our compressor and production and processing equipment products. In addition, we manufacture tanks for tank farms and critical process equipment for refinery and petrochemical facilities and other vessels used in the production, processing and treating of crude oil and natural gas. Steel prices can fluctuate widely and represent a significant portion of the cost of raw materials for these products. Increases in raw material costs cannot always be offset by increases in our products’ sales prices. While many of our materials and components are available from multiple suppliers at competitive prices, we obtain some of the components, including compressors and engines, used in our products from a limited group of suppliers. We occasionally experience long lead times for components, including compressors and engines, from our suppliers and, therefore, we may at times make purchases in anticipation of future orders.

Environmental and Other Regulations

Government Regulation

Our operations are subject to stringent and complex U.S. federal, state, local and international laws and regulations that could have a material impact on our operations or financial condition. Our operations are regulated under a number of laws governing, among other things, discharges of substances into the air, ground and regulated waters, the generation, transportation, treatment, storage and disposal of hazardous and non-hazardous substances, disclosure of information about hazardous materials used or produced in our operations, and occupational health and safety.

Table of Contents


Compliance with these environmental laws and regulations may expose us to significant costs and liabilities and cause us to incur significant capital expenditures in our operations. Failure to comply with these laws and regulations may result in the assessment of administrative, civil and criminal penalties, imposition of investigatory and remedial obligations, and the issuance of injunctions delaying or prohibiting operations. In certain circumstances, laws may impose strict, joint and several liability without regard to fault or the legality of the original conduct on classes of persons who are considered to be responsible for the release of hazardous substances into the environment. In addition, it is not uncommon for third parties to file claims for personal injury, property damage and recovery of response costs allegedly caused by hazardous substances or other pollutants released into the environment. We currently own or lease, and in the past have owned or leased, a number of properties that have been used in support of our operations for a number of years. Although we have utilized operating and disposal practices that were standard in the industry at the time, hydrocarbons, hazardous substances, or other regulated wastes may have been disposed of, or released, on or under the properties owned orby us, leased by us or on or under other locations where such materials have been taken for disposal by companies sub-contracted by us. In addition, many of these properties have been previously owned or operated by third parties whose treatment and disposal or release of hydrocarbons, hazardous substances or other regulated wastes waswere not under our control. These properties and the materials released or disposed thereon may be subject to various laws that could require us to remove or remediate historical property contamination, or to perform certain operations to prevent future contamination. We are not currently under any order requiring that we undertake or pay for any cleanup activities. However, we cannot provide any assurance that we will not receive any such order in the future.

The clear trend in environmental regulation is to place more restrictions on activities that may affect the environment, and thus, any changes in these laws and regulations that result in more stringent and costly waste handling, storage, transport, disposal, emission or remediation requirements could have a material adverse effect on our results of operations and financial position.

Employees

As of December 31, 2015,2017, we had approximately 7,0004,500 employees. Many of our employees outside of the U.S. are covered by collective bargaining agreements. We generally consider our relationships with our employees to be satisfactory.

Item 1A.  Risk Factors

As described in Part I (“Disclosure Regarding Forward-Looking Statements”), this report contains forward-looking statements regarding us, our business and our industry. The risk factors described below, among others, could cause our actual results to differ materially from the expectations reflected in the forward-looking statements. If any of the following risks actually occurs, our business, financial condition, results of operations and cash flows could be negatively impacted.

Risks RelatingRelated to Our Business and Industry

The restatement of our financial statements may lead to additional risks and uncertainties, including loss of investor and counterparty confidence and negative impacts on our stock price.

We have restated our financial statements for the years ended December 31, 2015, 2014 and 2013 (including the unaudited quarterly periods within 2015 and 2014) to correct accounting errors primarily related to Belleli EPC projects within our product sales segment and non-income-based tax receivables in Brazil. For discussion of the accounting errors identified and the restatement adjustments, see Note 3 to the Financial Statements and the Explanatory Note immediately preceding the Table of Contents. In connection with this restatement of our prior financial statements, we have identified material weaknesses in our internal control over financial reporting, and management has concluded that our internal control over financial reporting and disclosure controls and procedures were ineffective as of December 31, 2015. For a description of the material weaknesses, see “Part II, Item 9A — Controls and Procedures.”

As a result of the circumstances giving rise to the restatement, we have become subject to a number of additional costs and risks, including unanticipated costs for accounting and legal fees in connection with or related to the restatement and the remediation of our ineffective disclosure controls and procedures and material weaknesses in internal control over financial reporting. In addition, the attention of our management team has been diverted by these efforts. The SEC is conducting an investigation into the circumstances giving rise to the restatement. We could be subject to further regulatory, or stockholder or other actions in connection with the restatement in the future. The current SEC investigation and any future proceedings will, regardless of the outcome, consume management’s time and attention and may result in additional legal, accounting, insurance and other costs. In addition, the restatement and related matters could impair our reputation and could cause our counterparties to lose confidence in us. Each of these occurrences could have an adverse effect on our business, results of operations, financial condition and stock price.

Continued lowLow oil and natural gas prices could continue to depress or further decreasereduce demand or pricing for our natural gas compression and oil and natural gas production and processing equipment and services and, as a result, adversely affect our business.

Our results of operations depend upon the level of activity in the global energy market, including oil and natural gas development, production, processing and transportation. Oil and natural gas prices and the level of drilling and exploration activity can be volatile. For example, oil and natural gas exploration and development activity and the number of well completions typically decline when there is a sustained reduction in oil or natural gas prices or significant instability in energy markets. Even the perception of longer-term lower oil or natural gas prices by oil and natural gas exploration, development and production companies can result in their decision to cancel, reduce or postpone major expenditures or to reduce or shut in well production.

Global oilOil and U.S. natural gas prices have declined significantly since the third quarter of 2014. For example, the Henry Hub spot price for natural gas was $2.28 per MMBtu at December 31, 2015, which was approximately 27% and 47% lower than prices at December 31, 2014 and 2013, respectively, and the U.S. natural gas liquid composite price was approximately $4.72 per MMBtulevel of drilling and exploration activity can be volatile. In periods of volatile commodity prices, the timing of any change in activity levels by our customers is difficult to predict. As a result, our ability to project the anticipated activity level for the monthour business, and particularly our product sales segment may be limited.

During periods of November 2015, which was approximately 16% and 56% lower than prices for the months of December 2014 and 2013, respectively. These lower prices led to reduced drilling of gas wells in North America in 2015. In addition, the West Texas Intermediate crude oil spot price as of December 31, 2015 was approximately 31% and 62% lower than prices at December 31, 2014 and 2013, respectively, which led to reduced drilling of oil wells in 2015. More recently, West Texas Intermediate crude oil prices continued to decline during 2016, represented by a spot price decrease of 9% at January 31, 2016 compared to December 31, 2015. If oil or natural gas exploration and development activities do not improveprices, our customers typically decrease their capital expenditures, which generally results in North America or other parts of the world, the level of productionlower activity and the demand for our contract operations services, natural gas compression equipment and oil and natural gas production and processing equipment could continue to remain depressed or could further decrease, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.levels. A reduction in demand for our products and services could also force us to reduce our pricing substantially, which could have a material adverse effect on our business, financial condition, results of operations and cash flows. For example, due to the low oil and natural gas price environment during 2015 and the majority of 2016, our customers sought to reduce their capital and operating expenditure requirements, and as a result, the demand and pricing for the equipment we manufacture was adversely impacted. Moreover, a reduction in demand for our products and services could result in our customers seeking to preserve capital by canceling contracts, canceling or delaying scheduled maintenance of their existing natural gas compression and oil and natural gas production and processing equipment, determining not to enter intoceasing commitments for new contract operations service contracts or purchase new compression and oil and natural gas production and processing equipment, or canceling or delaying orders for our products and services, any of which could have a material adverse effect on our business, financial condition, results of operations and cash flows. For example, third party booking activity levels for our manufactured products in each of our North America and international markets during the year ended December 31, 2015 have decreased by approximately 63% and 54%, respectively, compared to the year ended December 31, 2014, and each of our North America and international markets’ product sales backlog as of December 31, 2015 decreased by approximately 58% and 40%, respectively, compared to December 31, 2014. In periods of volatile commodity prices, the timing of any change in activity levels by our customers is difficult to predict. As a result, our ability to project the anticipated activity level for our business, and particularly our product sales segment, in 2016 and beyond is limited. If these reduced booking levels persist for a sustained period, we could experience a material adverse effect on our business, financial condition, results of operations and cash flows.

The erosion of the financial condition of our customers could adversely affect our business.

Many of our customers finance their exploration and development activities through cash flowflows from operations, the incurrence of debt or the issuance of equity. During times when the oil or natural gas markets weaken, our customers are more likely to experience a downturn in their financial condition. A reduction in borrowing bases under reserve-based credit facilities, the lack of availability of debt or equity financing or other factors that negatively impact our customers’ financial condition could result in our customers seeking to preserve capital by reducing prices under existing contracts or cancelling contracts with us, determining not to renew contracts with us, cancelling or delaying scheduled maintenance of their existing natural gas compression and oil and natural gas production and processing equipment, determining not to enter into contract operations agreements or not to purchase new compression and oil and natural gas production and processing equipment, or determining to cancel or delay orders for our products and services. Any such action by our customers would reduce demand for our products and services. Reduced demand for our products and services could adversely affect our business, financial condition, results of operations and cash flows. In addition, in the event of the financial failure of a customer, we could experience a loss on all or a portion of our outstanding accounts receivable associated with that customer.

Failure to maintain expense levels in line with activity decreases could adversely affect our business.

Given the significant reduction in industry capital spending since the third quarter of 2014 and the resulting decrease in demand for our products and services, we have and will continue to reduce our expense levels, including personnel head count and costs, to protect our profitability. Some of these expenses are difficult to reduce, and if we are not able to reduce them commensurate with the level of activity decreases, our profitability will be negatively impacted. Any failure to reduce these costs in a timely manner could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Failure to timely and cost-effectively execute on larger projects could adversely affect our business.

Some of our projects have a relatively larger size and scope than the majority of our projects, which can translate into more technically challenging conditions or performance specifications for our products and services. Contracts with our customers for these projects typically specify delivery dates, performance criteria and penalties for our failure to perform. Any failure to estimate the cost of and execute suchthese larger projects in a timely and cost effective manner could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We have incurred and may in the future incur losses on fixed-price contracts, which constitute a significant portion of our product sales business.

In connection with projects and services performed under fixed-price contracts, we generally bear the risk of cost over-runs, operating cost inflation, labor availability and productivity, and supplier and subcontractor pricing and performance, unless additional costs result from customer-requested change orders. Under both our fixed-price contracts and our cost-reimbursable contracts, we may rely on third parties for many support services, and we could be subject to liability for their failures. For example, we have experienced losses on certain large manufacturing projects that have negatively impacted our product sales results. Any failure to accurately estimate our costs and the time required for a fixed-price manufacturing project at the time we enter into a contract could have a material adverse effect on our business, financial condition, results of operations and cash flows.

There are many risks associated with conductingOur operations in international markets.markets are subject to many risks.

Our contract operations and aftermarket services businesses, and a portion of our product sales business, are conducted in countries outside the U.S. We currently operate in manyapproximately 30 countries. The countries with our largest contract operations businesses include Mexico, Brazil and Argentina. We are exposed to risks inherent in doing business in each of the countries where we operate. Our operations are subject to various risks unique to each country that could have a material adverse effect on our business, financial condition, results of operations and cash flows. For example, in 2009 Petroleos de Venezuela S.A. (“PDVSA”), the Venezuelan state-owned oil company, assumed control over substantially all of our assets and operations in Venezuela.

In April 2012, Argentina assumed control over its largest oil and gas producer, Yacimientos Petroliferos Fiscales (“YPF”). We had approximately 502,000 horsepower of compression in Argentina as of December 31, 2015, and we generated $172.0 million of revenue in Argentina, including $80.2 million of revenue from YPF, during the year ended December 31, 2015. As of December 31, 2015, $8.1 million of our cash was in Argentina. As is not uncommon during periods of low commodity prices, we have recently been requested to provide modest pricing reductions to YPF for certain of our services and reached a mutually acceptable agreement. This request for pricing reductions was unrelated to the nationalization of YPF, which has not had a direct impact on our business to date. We are unable to predict what further effect, if any, the nationalization of YPF will have on our business in Argentina going forward, or whether Argentina will nationalize additional businesses in the oil and gas industry; however, the nationalization of YPF, the nationalization of additional businesses or the taking of other actions listed below by Argentina could have a material adverse effect on our business, financial condition, results of operations and cash flows.

More generally in Argentina, the ongoing social, political, economic and legal climate has given rise to significant uncertainties about the country’s economic and political future. After the presidential election in late 2011, the Argentine government increasingly used foreign-exchange, price, trade and capital controls to attempt to address the country’s economic challenges. In recent years, Argentina’s regulations have at times restricted foreign exchange, including exchanging Argentine pesos for U.S. dollars in certain cases, and during these periods we were unable to freely repatriate cash from Argentina. In late 2015, following the election of a new president, some of the currency restrictions were lifted and we have been able to exchange Argentine pesos for U.S. dollars at market rates. However, if we experience restrictions in the future, the cash flow from our operations in Argentina may not be a reliable source of funding for our operations outside of Argentina, which could limit our ability to grow. Future restrictions on our ability to exchange Argentine pesos for U.S. dollars would also subject us to risk of currency devaluation on future earnings in Argentina. Following the easing of the restrictions in late 2015, the Argentine peso devalued by 32% against the U.S. dollar. During the year ended December 31, 2015, we recorded a $1.0 million foreign currency gain in our statements of operations from remeasuring foreign currency accounts into the functional currency in Argentina. Prior to the currency restrictions being lifted in Argentina in late 2015, we used Argentine pesos to purchase certain short-term investments in Argentine government issued U.S. dollar denominated bonds. The effective peso to U.S. dollar exchange rate embedded in the purchase price of $18.4 million of bonds purchased during the year ended December 31, 2015 resulted in our recognition of a loss of $4.9 million which is included in other (income) expense, net, in our statements of operations.

The Argentine government may adopt additional regulations or policies in the future that may impact, among other things, (i) the timing of and our ability to repatriate cash from Argentina to the U.S. and other jurisdictions, (ii) the value of our assets and business in Argentina and (iii) our ability to import into Argentina the materials necessary for our operations. Any such changes could have a material adverse effect on our operations in Argentina and may negatively impact our business, results of operations, financial condition and cash flows.

We generate a significant portion of our revenue in Mexico from Petroleos Mexicanos (“Pemex”). Pemex is a decentralized public entity of the Mexican government, and, therefore, the Mexican government controls Pemex, as well as its annual budget, which is approved by the Mexican Congress. The Mexican government may cut spending in the future. These cuts could adversely affect Pemex’s annual budget and its ability to engage us in the future or compensate us for our services. Recently, the Mexican government implemented an energy industry reform that will allow the government to grant non-Mexican companies the opportunity to enter into contracts and licenses to explore and drill for oil and natural gas in Mexico. Any impact from this reform on our business in Mexico is uncertain.

Also, during the past several years, incidents of security disruptions in many regions of Mexico have increased, including drug cartel related activity. Certain incidents of violence have occurred in regions we serve and have resulted in the temporary disruption of our operations. These disruptions could continue or increase in the future. To the extent that such security disruptions continue or increase, our operations will continue to be affected, and the levels of revenue and operating cash flow from our Mexican operations could be reduced.

We generate a significant portion of our revenue in Brazil from Petroleos Brasileiro (“Petrobras”), a government-controlled energy company. A significant number of senior executives at Petrobras resigned their positions in connection with a widely publicized corruption investigation. In addition, Petrobras recently announced further reductions to its long-term capital expenditures budget. We expect these developments to disrupt Petrobras’ operations in the near term, which could in turn adversely affect our business and results of operations in Brazil.

With respect to any particular country in which we operate, the risks inherent in our activities may include the following, the occurrence of any of which could have a material adverse effect on our business, financial condition, results of operations and cash flows:

difficulties in managing international operations, including our ability to timely and cost effectively execute projects;

unexpected changes in regulatory requirements, laws or policies by foreign agencies or governments;

work stoppages;

training and retaining qualified personnel in international markets;

the burden of complying with multiple and potentially conflicting laws and regulations;

tariffs and other trade barriers;

actions by governments or national oil companies that result in the nullification or renegotiation on less than favorable terms of existing contracts, or otherwise result in the deprivation of contractual rights, and other difficulties in enforcing contractual obligations;

governmental actions that: result in restricting the movement of property or that impede our ability to import or export parts or equipment; require a certain percentage of equipment to contain local or domestic content; or require certain local or domestic ownership, control or employee ratios in order to do business in or obtain special incentives or treatment in certain jurisdictions;

foreign currency exchange rate risks, including the risk of currency devaluations by foreign governments;

difficulty in collecting international accounts receivable;

potentially longer receipt of payment cycles;

changes in political and economic conditions in the countries in which we operate, including general political unrest, the nationalization of energy related assets, civil uprisings, riots, kidnappings, violence associated with drug cartels and terrorist acts;

potentially adverse tax consequences or tax law changes;

currency controls or restrictions on repatriation of earnings;

expropriation, confiscation or nationalization of property without fair compensation;

the risk that our international customers may have reduced access to credit because of higher interest rates, reduced bank lending or a deterioration in our customers’ or their lenders’ financial condition;

complications associated with installing, operating and repairing equipment in remote locations;

limitations on insurance coverage;

inflation;

the geographic, time zone, language and cultural differences among personnel in different areas of the world; and

difficulties in establishing new international offices and the risks inherent in establishing new relationships in foreign countries.

In addition, we may expand our business in international markets where we have not previously conducted business. The risks inherent in establishing new business ventures, especially in international markets where local customs, laws and business procedures present special challenges, may affect our ability to be successful in these ventures or avoid losses that could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our contract operations segment is dependent on companies that are controlled by the government in which it operates.

The countries with our largest contract operations businesses include Mexico, Brazil and Argentina. We generate a significant portion of our revenue in these countries from national oil companies, including Yacimientos Petroliferos Fiscales in Argentina, Petroleos Mexicanos in Mexico and Petrobras in Brazil. Contracts with national oil companies may expose us to greater commercial, political and operational risks than we assume in other contracts. Our ability to resolve disputes or enforce contractual provisions may be negatively impacted by the significant bargaining leverage that national oil companies have over us. If our national oil company customers cancel some of our contracts and we are unable to secure new contracts on a timely basis and on substantially similar terms, or if a number of our contracts are renegotiated, it could adversely affect our business, financial position, results of operations or cash flows.

We are exposed to exchange rate fluctuations in the international markets in which we operate. A decrease in the value of any of these currencies relative to the U.S. dollar could reduce profits from international operations and the value of our international net assets.

We operate in many international countries. Wecountries and anticipate that there will be instances in which costs and revenues will not be exactly matched with respect to currency denomination. We generally do not hedge exchange rate exposures, which exposes us to the risk of exchange rate losses. Gains and losses from the remeasurement of assets and liabilities that are receivable or payable in currencycurrencies other than our subsidiaries’ functional currency are included in our statements of operations. In addition, currency fluctuations cause the U.S. dollar value of our international results of operations and net assets to vary with exchange rate fluctuations. ThisA decrease in the value of any of these currencies relative to the U.S. dollar could have a negative impact on our business, financial condition, or results of operations. In addition, fluctuations in currencies relative to currencies in which the earnings are generated may make it more difficult to perform period-to-period comparisons of our reported results of operations. Our material exchange rate exposure relates to intercompany loans to subsidiaries whose functional currencies are the Brazilian Real and the Euro, which loans carried balances of $59.4 million and $9.1 million U.S. dollars, respectively, as of December 31, 2015. In addition, Argentina’s regulations in recent years have at times restricted foreign exchange, including exchanging Argentine pesos for U.S. dollars in certain cases. In late 2015, following the election of a new president, some of the currency restrictions were lifted and we have been able to exchange Argentine pesos for U.S. dollars at market rates. Future restrictions on our ability to exchange Argentine pesos for U.S. dollars subject us to risk of currency devaluation on future earnings in Argentina. As of December 31, 2015, $8.1 million of ouroperations or cash was in Argentina.flows. As we expand geographically, we may experience economic loss and a negative impact on earnings or net assets solely as a result of foreign currency exchange rate fluctuations. Further,In the future, we may utilize derivative instruments to manage the risk of fluctuations in foreign currency exchange rates that could potentially impact our future earnings and forecasted cash flows. However, the markets in which we operate could restrict the removal or conversion of the local or foreign currency, resulting in our inability to hedge against some or all of these risks.

See further discussion of foreign exchange risks under Item 7A “Quantitative and Qualitative Disclosures about Market Risk” included elsewhere in this Annual Report.

We are involved in governmental and internal investigations, which are costly to conduct, may result in substantial financial and other penalties, and could adversely affect our business, financial condition and results of operations.

In March 2016, the Audit Committee of the Board of Directors retained legal counsel to conduct an internal investigation related to the application of percentage-of-completion accounting principles to specific Belleli EPC product sales projects. Our Belleli EPC business had historically been comprised of engineering, procurement and construction for the manufacture of tanks for tank farms and the manufacture of evaporators and brine heaters for desalination plants in the Middle East (referred to as “Belleli EPC” or the “Belleli EPC business” herein). On April 26, 2016, we filed a Form 8-K reporting the errors and possible irregularities at Belleli EPC. Contemporaneously with filing the Form 8-K, we self-reported these issues to the SEC. We continue to cooperate with the SEC in its ongoing investigation of this matter, which has included responding to a subpoena for documents related to the circumstances giving rise to the restatement as well as documents related to our compliance with the U.S. Foreign Corrupt Practices Act (“FCPA”), which were also provided to the Department of Justice (“DOJ”) at its request. We also have made the SEC and DOJ aware of our internal investigation regarding previously restated non-income-based tax receivables due to us from the Brazilian government. We could be subject to stockholder or other actions, or further regulatory actions, in connection with these issues in the future.

The SEC staff has notified us that they have concluded their investigation concerning our compliance with the FCPA and that they do not intend to recommend an enforcement action concerning our compliance with the FCPA. The DOJ has similarly informed us that it does not intend to proceed with any further investigation or enforcement. The SEC’s investigation related to the circumstances giving rise to the restatement is continuing, and we are presently unable to predict the duration, scope or results or whether the SEC will commence any legal action. If we are found to have violated securities laws or other federal statutes, we may be subject to criminal and civil penalties and other remedial measures, including, but not limited to injunctive relief, disgorgement, civil and criminal fines and penalties, modifications to business practices including the termination or modification of existing business relationships, modifications of compliance programs and the retention of a monitor to oversee compliance. The imposition of any of these sanctions or remedial measures could have a substantial amount of debt that could limit our ability to fund future growth and operations and increase our exposure to risk duringmaterial adverse economic conditions.

At December 31, 2015, we had approximately $530.8 million in outstanding debt obligations. Many factors, including factors beyond our control, may affect our ability to make paymentsimpact on our outstanding indebtedness. These factors include those discussed elsewhere in these Risk Factorsreputation, business, results of operations, financial condition, liquidity and those listed in the Disclosure Regarding Forward-Looking Statements section included in Part I of this report.

Our substantial debt and associated commitments could have important adverse consequences. For example, these commitments could:

make it more difficult for us to satisfy our contractual obligations;

increase our vulnerability to general adverse economic and industry conditions;stock price.

limit our ability to fund future working capital, capital expenditures, acquisitions or other corporate requirements;

increase our vulnerability to interest rate fluctuations because the interest payments on our debt are based upon variable interest rates and can adjust based upon our credit statistics;

limit our flexibility in planning for, or reacting to, changes in our business and our industry;

place us at a disadvantage compared to our competitors that have less debt or less restrictive covenants in such debt; and

limit our ability to refinance our debt in the future or borrow additional funds.

As a result of the delayed filing of our Form 10-Q for the quarters ended March 31, 2016, June 30, 2016 and September 30, 2016 with the SEC, we are not currently eligible to use a registration statement on Form S-3 to register the offer and sale of securities, which may adversely affect our ability to raise additional capital.

As a result of the delayed filing of our Form 10-Q for the quarters ended March 31, 2016, June 30, 2016 and September 30, 2016 with the SEC, we will not be eligible to register the offer and sale of our securities using a registration statement on Form S-3 until we have timely filed all periodic reports required under the Securities Exchange Act of 1934 for at least twelve calendar months. There can be no assurance that we will be able to timely file such reports in the future. In addition, it is possible that the SEC in connection with their investigation of the facts surrounding our restatement could further prolong our inability to register securities for sale to the public on Form S-3. As a result, should we wish to register the offer and sale of our securities to the public, our transaction costs and the amount of time required to complete the transaction could increase, making it more difficult to execute any such transaction timely and successfully and potentially harming our financial condition.

If we are unable to refinance our term loan when due on acceptable terms, we may experience a material adverse effect on our liquidity and financial condition.

In October 2015, we entered into a $245.0 million term loan, which will mature in November 2017. At or prior to the time the term loan matures, we will be required to refinance it and may enter into one or more new facilities, which could result in higher borrowing costs, issue equity, which would dilute our existing shareholders, or otherwise raise the funds necessary to repay the outstanding principal amount under the term loan. In connection with the Spin-off, our wholly owned subsidiary, Exterran Energy Solutions, L.P. (“EESLP”), contributed to a subsidiary of Archrock the right to receive, promptly following the occurrence of a qualified capital raise, a $25.0 million cash payment. No assurance can be given that we will be able to enter into new facilities or issue equity in the future on attractive terms or at all. If we are unable to obtain financing on acceptable terms, or at all, to refinance the remaining principal amount outstanding under our term loan, we would need to take other actions, including selling assets or seeking strategic investments from third parties, potentially on unfavorable terms, and deferring capital expenditures or other discretionary uses of cash. To the extent that were are unable to refinance our term loan or are required to take any such other action, we would experience a material adverse effect on our liquidity and financial condition.

Covenants in our credit agreement may impair our ability to operate our business.

The credit agreement related to our $925.0 million credit facility, consisting of a $680.0 million revolving credit facility expiring in November 2020 and a $245.0 million term loan facility expiring in November 2017, contains various covenants with which we, EESLP and our respective restricted subsidiaries must comply, including, but not limited to, limitations on the incurrence of indebtedness, investments, liens on assets, repurchasing equity, making distributions, transactions with affiliates, mergers, consolidations, dispositions of assets and other provisions customary in similar types of agreements. We are required to maintain, on a consolidated basis, a minimum interest coverage ratio of 2.25 to 1.00; a maximum total leverage ratio of 3.75 to 1.00 prior to the completion of a qualified capital raise and 4.50 to 1.00 thereafter; and, following the completion of a qualified capital raise, a maximum senior secured leverage ratio of 2.75 to 1.00. If we fail to remain in compliance with these restrictions and financial covenants, we would be in default under our credit agreement. In addition, if we experience a material adverse effect on our assets, liabilities, financial condition, business or operations that, taken as a whole, impact our ability to perform our obligations under our credit agreement, this could lead to a default. If the repayment obligations on any of our indebtedness were to be accelerated, we may not be able to repay the debt or refinance the debt on acceptable terms, and our financial position would be materially adversely affected. As of December 31, 2015, we were in compliance with all financial covenants under our credit agreement.

We may be vulnerable to interest rate increases due to our floating rate debt obligations.

As of December 31, 2015, we had $530.0 million of outstanding borrowings that are subject to floating interest rates. Changes in economic conditions outside of our control could result in higher interest rates, thereby increasing our interest expense and reducing the funds available for capital investment, operations or other purposes. A 1% increase in the effective interest rate on our outstanding debt subject to floating interest rates at December 31, 2015 would result in an annual increase in our interest expense of approximately $5.3 million.

The termination of or any price reductions under certain of our contract operations services contracts could have a material impact on our business.

The termination of or a demand by our customers to reduce prices under certain of our contract operations services contracts may lead to a reduction in our revenues and net income, which could have a material adverse effect upon our business, financial condition, results of operations and cash flows. In addition, we may be unable to renew, or enter into new, contracts with customers on favorable commercial terms, if at all. To the extent we are unable to renew our existing contracts or enter into new contracts on terms that are favorable to us or to successfully manage our overall contract mix over time, our business, results of operations and cash flows may be adversely impacted.

Product sales backlog may be subject to unexpected adjustments and cancellations.

The revenues projected in our product sales backlog may not be realized or, if realized, may not result in profits. Due to potential project cancellations or changes in project scope and schedule, we cannot predict with certainty when or if backlog will be performed. In addition, even where a project proceeds as scheduled, it is possible that contracted parties may default and fail to pay amounts owed to us or poor project performance could increase the cost associated with a project. Delays, suspensions, cancellations, payment defaults, scope changes and poor project execution could materially reduce the revenues and reduce or eliminate profits that we actually realize from projects in backlog. We may be at greater risk of delays, suspensions and cancellations during periods of low oil and natural gas prices.

Reductions in our product sales backlog due to cancellation or modification by a customer or for other reasons may adversely affect, potentially to a material extent, the revenues and earnings we actually receive from contracts included in our backlog. Many of the contracts in our product sales backlog provide for cancellation fees in the event customers cancel projects. These cancellation fees usually provide for reimbursement of our out-of-pocket costs, revenues for work performed prior to cancellation and a varying percentage of the profits we would have realized had the contract been completed. However, we typically have no contractual right upon cancellation to the total revenue reflected in our backlog. Projects may remain in our backlog for extended periods of time. If we experience significant project terminations, suspensions or scope adjustments to contracts reflected in our backlog, our financial condition, results of operations and cash flows may be adversely impacted.

From time to time, we are subject to various claims, litigation and other proceedings that could ultimately be resolved against us, requiring material future cash payments or charges, which could impair our financial condition or results of operations.

The size, nature and complexity of our business make us susceptible to various claims, both in litigation and binding arbitration proceedings. We are currently, and may in the future become, subject to various claims, which, if not resolved within amounts we have accrued, could have a material adverse effect on our financial position, results of operations or cash flows. Similarly, any claims, even if fully indemnified or insured, could negatively impact our reputation among our customers and the public, and make it more difficult for us to compete effectively or obtain adequate insurance in the future.

We depend on particular suppliers and aremay be vulnerable to product shortages and price increases.

Some of the components used in our products are obtained from a single source or a limited group of suppliers. Our reliance on these suppliers involves several risks, including price increases, inferior component quality and a potential inability to obtain an adequate supply of required components in a timely manner. We do not have long-term contracts with some of these sources, and the partial or complete loss of certain of these sources could have a negative impact on our results of operations and could damage our customer relationships. Further, a significant increase in the price of one or more of these components could have a negative impact on our results of operations.

We face significant competitive pressures that may cause us to lose market share and harm our financial performance.

Our businesses face intense competition and have low barriers to entry. Our competitors may be able to adapt more quickly to technological changes within our industry and changes in economic and market conditions and more readily take advantage of acquisitions and other opportunities. Our ability to renew or replace existing contract operations service contracts with our customers at rates sufficient to maintain current revenue and cash flows could be adversely affected by the activities of our competitors. If our competitors substantially increase the resources they devote to the development and marketing of competitive products, equipment or services or substantially decrease the price at which they offer their products, equipment or services, we may not be able to compete effectively.

In addition, we could face significant competition from new entrants into the compression services and product sales businesses. Some of our existing competitors or new entrants may expand or develop new processing, treating and compression unitsequipment that would create additional competition for the products, equipment or services we provide to our customers.

Our ability to manage and grow our business effectively may be adversely affected if we lose management or operational personnel.

We also may notbelieve that our ability to hire, train and retain qualified personnel will continue to be ablechallenging and important. The supply of experienced operational and field personnel, in particular, decreases as other energy and manufacturing companies’ needs for the same personnel increase. Our ability to take advantagegrow and to continue our current level of certain opportunities or make certain investments becauseservice to our customers will be adversely impacted if we are unable to successfully hire, train and retain these important personnel.

Our employees work on projects that are inherently dangerous. If we fail to maintain safe work sites, we can be exposed to significant financial losses and reputational harm.

Safety is a leading focus of our debt levelsbusiness, and our other obligations. Assafety record is critical to our reputation and is of paramount importance to our employees, customers and stockholders. However, we often work on large-scale and complex projects which can place our employees and others near large mechanized equipment, moving vehicles, dangerous processes and in challenging environments. Although we have a U.S.-domiciledfunctional group whose primary purpose is to implement effective quality, health, safety, environmental and security procedures throughout our company, if we fail to implement effective safety procedures, our employees and others may become injured, disabled or lose their lives, our projects may be delayed and we may be exposed to litigation or investigations.

Unsafe conditions at project work sites also face a higher corporate tax rate thanhave the potential to increase employee turnover, increase project costs and raise our competitorsoperating costs. Additionally, many of our customers require that are domiciledwe meet certain safety criteria to be eligible to bid for contracts and our failure to maintain adequate safety standards could result in other jurisdictions.reduced profitability, or lost project awards or customers. Any of these competitive pressuresthe foregoing could result in financial losses or reputational harm, which could have a material adverse effectimpact on our business, financial condition and results of operations.

We may face challenges as a result of being a smaller, less diversified business than we were as part of Archrock prior to the Spin-off.

Because our business represents a subset of Archrock’s business immediately prior to the Spin-off, we have access to a smaller pool of assets, fewer personnel and less operational diversity, among other challenges, than we did as a part of Archrock. As a result, we may be unable to attract or retain customers that prefer to contract with more diversified companies that are able to operate on a larger scale than us. Our inability to attract or retain such customers may negatively impact our business and cause our financial condition and results of operations to suffer. In addition, as a smaller and less diversified business we may be more adversely impacted by changes in our business than we would have been had we remained a part of Archrock.

Our operations entail inherent risks that may result in substantial liability. We do not insure against all potential losses and could be seriously harmed by unexpected liabilities.

Our operations entail inherent risks, including equipment defects, malfunctions and failures and natural disasters, which could result in uncontrollable flows of natural gas or well fluids, fires and explosions. These risks may expose us, as an equipment operator and developer, to liability for personal injury, wrongful death, property damage, pollution and other environmental damage. The insurance we carry against many of these risks may not be adequate to cover our claims or losses. In addition, we are substantially self-insured for workers’ compensation, employer’s liability, property, auto liability, general liability and employee group health claims in view of the relatively high per-incident deductibles we absorb under our insurance arrangements for these risks. Further, insurance covering the risks we expect to face or in the amounts we desire may not be available in the future or, if available, the premiums may not be commercially justifiable. If we were to incur substantial liability and such damages were not covered by insurance or were in excess of policy limits, or if we were to incur liability at a time when we are not able to obtain liability insurance, our business, financial condition and results of operations could be negatively impacted.

We may be subject to risks arising from changes in technology.

The supply chains in which we operate are subject to technological changes and changes in customer requirements. We may not successfully develop or implement new or modified types of products or technologies that may be required by our customers in the future. Further, the development of new technologies by competitors that may compete with our technologies could reduce demand for our products and affect our financial performance. Should we not be able to maintain or enhance the competitive values of our products or develop and introduce new products or technologies successfully, or if new products or technologies fail to generate sufficient revenues to offset research and development costs, our business, financial condition and operating results could be materially adversely affected.

Cyber-attacks or terrorism could affect our business.

We may be adversely affected by problems such as cyber-attacks, computer viruses or terrorism that may disrupt our operations and harm our operating results. Our industry requires the continued operation of sophisticated information technology systems and network infrastructure. Despite our implementation of security measures, our technology systems are vulnerable to disability or failures due to hacking, viruses, acts of war or terrorism and other causes. If our information technology systems were to fail and we were unable to recover in a timely way, we might be unable to fulfill critical business functions, which could have a material adverse effect on our business, financial condition and results of operations.

In addition, our assets may be targets of terrorist activities that could disrupt our ability to service our customers. We may be required by our regulators or by the future terrorist threat environment to make investments in security that we cannot currently predict. The implementation of security guidelines and measures and maintenance of insurance, to the extent available, addressing such activities could increase costs. These types of events could materially adversely affecthave a material adverse effect on our business and results of operations. In addition, these types of events could require significant management attention and resources, and could adversely affect our reputation among customers and the public.

We are subject to a variety of governmental regulations; failure to comply with these regulations may result in administrative, civil and criminal enforcement measures and changes in these regulations could be adversely affected by violationsincrease our costs or liabilities.

We are subject to a variety of the U.S. Foreign Corrupt Practices Act (“FCPA”), similar worldwide anti-briberyfederal, state, local and international laws and trade control laws.

Many of these laws and regulations are foundcomplex, change frequently, are becoming increasingly stringent, and the cost of compliance with these requirements can be expected to have violated the FCPA or other legal requirements,increase over time. From time to time, as part of our operations we may be subject to compliance audits by regulatory authorities in the various countries in which we operate. Our failure to comply with these laws and regulations may result in a variety of administrative, civil and criminal enforcement measures, including assessment of monetary penalties, imposition of remedial requirements and civil penaltiesissuance of injunctions as to future compliance, any of which may have a negative impact on our financial condition, profitability and other remedial measures, which could materially harm our reputation, business, results of operations, financial condition and liquidity.operations.

Our international operations require us to comply with U.S. and international laws and regulations, including those involving anti-bribery and anti-corruption. For example, the FCPA and similar laws and regulations prohibit improper payments to foreign officials for the purpose of obtaining or retaining business or gaining any business advantage.

We operate in many parts of the world that experience high levels of corruption, and our business brings us in frequent contact with foreign officials. Our compliance policies and programs mandate compliance with all applicable anti-corruption laws but may not be completely effective in ensuring our compliance. Our training and compliance program and our internal control policies and procedures may not always protect us from violations committed by our employees or agents. Actual or allegedIf we undergo an investigation of potential violations of anti-corruption laws or if we fail to comply with these laws, could disrupt our business and cause us towe may incur significant legal expenses or be subject to criminal and civil penalties and other sanctions and remedial measures, which could result inhave a material adverse effectimpact on our reputation, business, financial condition, results of operations financial condition and liquidity. If we are found to be liable for FCPA or other anti-bribery law violations due to our own acts or omissions or due to the acts or omissions of others (including our joint venture partners, agents or other third party representatives), we could suffer from severe civil and criminal penalties or other sanctions, which could materially harm our reputation, business, results of operations, financial condition and liquidity. Separately, we may face competitive disadvantages if our competitors are able to secure business, licenses or other advantages by making payments or using other methods that are prohibited by U.S. and international laws and regulations.

We also are subject to other laws and regulations governing our operations, including regulations administered by the U.S. Department of Treasury’s Office of Foreign Asset Control and various non-U.S. government entities, including applicable export control regulations, economic sanctions on countries and persons and customs requirements. Trade control laws are complex and constantly changing. Our compliance policies and programs increase our cost of doing business and may not work effectively to ensure our compliance with trade control laws. If we undergo an investigation of potential violations of trade control laws by U.S. or foreign authorities or if we fail to comply with these laws, we may incur significant legal expenses or be subject to criminal and civil penalties and other sanctions and remedial measures, which could have a material adverse impact on our reputation, business, financial condition and results of operations, financial condition, liquidity and stock price.operations.

We are involved in governmental and internal investigations, which are costly to conduct and may result in substantial financial and other penalties, as well as adverse effects on our business and financial condition.

In March 2016, the Audit Committee of the Board of Directors retained legal counsel to conduct an internal investigation related to the application of percentage-of-completion accounting principles to specific Belleli EPC engineering, procurement and construction projects in the Middle East. On April 26, 2016, we filed a Form 8-K reporting the errors and possible irregularities at Belleli EPC. Contemporaneously with filing the Form 8-K, we self-reported these issues to the SEC. We are cooperating with the SEC in its investigation of this matter, including responding to a subpoena for documents related to the circumstances giving rise to the restatement as well as documents related to our compliance with the FCPA, which are also being provided to the Department of Justice (“DOJ”) at its request. The FCPA related requests in the SEC subpoena pertain to our policies and procedures, information about our third-party sales agents, and documents related to historical internal investigations completed prior to November 2015. We also have made the SEC and DOJ aware of our internal investigation regarding prior year non-income-based tax receivables due to us from the Brazilian government.

The government investigations are continuing, and we are presently unable to predict the duration, scope or results of them or whether the SEC or DOJ will commence any legal actions. If we are found to have violated securities laws or other federal statutes, including the FCPA, we may be subject to criminal and civil penalties and other remedial measures, including, but not limited to injunctive relief, disgorgement, civil and criminal fines and penalties, modifications to business practices including the termination or modification of existing business relationships, modifications of compliance programs and the retention of a monitor to oversee compliance. The imposition of any of these sanctions or remedial measures could have a material adverse impact on our reputation, business, results of operations, financial condition, liquidity and stock price.

Tax legislation and administrative initiatives or challenges to our tax positions could adversely affect our results of operations and financial condition.

We operate in locations throughout the U.S. and internationally and, as a result, we are subject to the tax laws and regulations of U.S. federal, state, local and foreign governments. From time to time, various legislative or administrative initiatives may be proposed that could adversely affect our tax positions. There can be no assurance that our tax provision or tax payments will not be adversely affected by these initiatives. In addition, U.S. federal, state and local and internationalforeign tax laws and regulations are extremely complex and subject to varying interpretations. Moreover, economic and political pressures to increase tax revenue in various jurisdictions may make resolving tax disputes favorably more difficult. There can be no assurance that our tax positions will not be challenged by relevant tax authorities or that we would be successful in any such challenge. Changes to our tax positions resulting from tax legislation and administrative initiatives or challenges from taxing authorities could adversely affect our results of operations and financial condition.

TableOn December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Reform Act”). The Tax Reform Act makes broad and complex changes to the U.S. tax code, including, but not limited to, (1) reducing the U.S. federal corporate tax rate from 35% to 21%; (2) requiring companies to pay a one-time transition tax on certain unrepatriated earnings of Contentsforeign subsidiaries; (3) generally eliminating U.S. federal income taxes on dividends from foreign subsidiaries; (4) requiring a current inclusion in U.S. federal taxable income of certain earnings of controlled foreign corporations; (5) eliminating the corporate alternative minimum tax (“AMT”) and changing how existing AMT credits can be realized; (6) creating the base erosion anti-abuse tax, a new minimum tax; (7) creating a new limitation on deductible interest expense; and (8) changing rules related to uses and limitations of net operating loss carryforwards created in tax years beginning after December 31, 2017. Guidance under U.S. GAAP requires that the impact of tax legislation be recognized in the period in which the law was enacted.

In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118, which addresses how a company recognizes provisional amounts when a company does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete its accounting for the effect of the changes in the Tax Reform Act. The measurement period ends when a company has obtained, prepared and analyzed the information necessary to finalize its accounting, but cannot extend beyond one year.

While we recorded provisional estimates of the impact of the Tax Reform Act, the final impact may differ from these estimates, due to, among other things, changes in our interpretations and assumptions, additional guidance that may be issued by the government and actions we may take as a result of these enacted tax laws. We are continuing to analyze additional information to determine the final impact as well as other impacts of the Tax Reform Act. Any adjustments recorded to the provisional amounts will be included in income from operations as an adjustment to our 2018 financial statements.

U.S. federal, state and local legislative and regulatory initiatives relating to hydraulic fracturing as well as governmental reviews of such activities could result in increased costs and additional operating restrictions or delays in the completion of oil and natural gas wells, and adversely affect demand for our products.

Hydraulic fracturing is an important and common practice that is used to stimulate production of natural gas and/or oil, from dense subsurface rock formations. Hydraulic fracturing involves the injection of water, sand or alternative proppant and chemicals under pressure into target geological formations to fracture the surrounding rock and stimulate production. Hydraulic fracturing is typically regulated by state agencies, but recently, there has been increased public concern regarding an alleged potential for hydraulic fracturing to adversely affect drinking water supplies, and proposals have been made to enact separate U.S. federal, state and local legislation that would increase the regulatory burden imposed on hydraulic fracturing.


16



For example, at the U.S. federal level, the EPAU. S. Environmental Protection Agency (“EPA”) issued an Advance Notice of Proposed Rulemaking to collect data on chemicals used in hydraulic fracturing operations under Section 8 of the Toxic Substances Control Act, and proposed regulations under the CWA governing wastewater discharges from hydraulic fracturing and certain other natural gas operations. Also, the U.S. Department of the Interior released a final rule that updates existing regulation of hydraulic fracturing activities on U.S. federal lands, including requirements for chemical disclosure, wellbore integrity and handling of flowback water. The final rule was expected to be effective on June 24, 2015, but, on September 30, 2015, a federal district court issued a preliminary injunction preventing implementation of the rule. In addition, several governmental reviews are underway that focus on environmental aspects of hydraulic fracturing activities. In June 2015, the EPA released its draft report on the potential impacts of hydraulic fracturing on drinking water resources, which concluded that hydraulic fracturing activities have not led to widespread, systemic impacts on drinking water sources in the U.S., although there are above and below ground mechanisms by which hydraulic fracturing activities have the potential to impact drinking water sources. The draft report is expected to be finalized after a public comment period and a formal review by EPA’s Science Advisory Board. In addition, the White House Council on Environmental Quality is coordinating an administration-wide review of hydraulic fracturing practices. The results of this study or similar governmental reviews could spur initiatives to further regulate hydraulic fracturing under the Safe Drinking Water Act of 1974 or otherwise.

At the state level, several states have adopted or are considering legal requirements that could impose more stringent permitting, disclosure, and well construction requirements on hydraulic fracturing activities. For example in May 2013, the Texas Railroad Commission adopted new rules governing well casing, cementing and other standards for ensuring that hydraulic fracturing operations do not contaminate nearby water resources. Local governments may also seek to adopt ordinances within their jurisdictions regulating the time, place and manner of, or prohibiting the performance of, drilling activities in general or hydraulic fracturing activities in particular. If new or more stringent federal, state or local legal restrictions relating to the hydraulic fracturing process are adopted in areas where our natural gas exploration and production customers operate, those customers could incur potentially significant added costs to comply with such requirements, experience delays or curtailment in the pursuit of exploration, development or production activities and perhaps even be precluded from drilling wells. Any such restrictions could reduce demand for our products, and as a result could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We are subjectThe inability to a varietyacquire adequate supplies of governmental regulations; failurewater for our or our customers’ operations or the inability to comply with these regulations maydispose of or recycle the water we or our customers’ use economically and in an environmentally safe manner could result in administrative, civilincreased costs and criminal enforcement measuresadditional operating restrictions or delays in the completion of oil and changesnatural gas wells, and adversely affect demand for our products.

Oil and gas development activities require the use of water. For example, the hydraulic fracturing process to produce commercial quantities of oil and natural gas from many reservoirs requires the use and disposal of significant quantities of water. In certain areas, there may be a scarcity of water for drilling activities due to various factors, including insufficient local aquifer capacity or government regulations restricting the use of water. Our customers’ inability to secure sufficient amounts of water, or our or our customers’ inability to dispose of or recycle the water used in theseoperations, could adversely impact our or our customers’ operations in certain areas. The imposition of new environmental initiatives and regulations, could increasefurther restrict our costs or liabilities.

We are subjectour customers’ ability to conduct certain operations disposal of waste, including, but not limited to, produced water, drilling fluids and other materials associated with the exploration, development or production of oil and natural gas. Any such restrictions could reduce demand for our products, and as a variety of U.S. federal, state, local and international laws and regulations relating to, for example, export controls, currency exchange, labor and employment and taxation. Many of these laws and regulations are complex, change frequently, are becoming increasingly stringent, and the cost of compliance with these requirements can be expected to increase over time. From time to time, as part of our operations we may be subject to compliance audits by regulatory authorities in the various countries in which we operate. Our failure to comply with these laws and regulations may result in a variety of administrative, civil and criminal enforcement measures, including assessment of monetary penalties, imposition of remedial requirements and issuance of injunctions as to future compliance, any of which maycould have a negative impactmaterial adverse effect on our business, financial condition, profitability and results of operations.operations and cash flows.

We are subject to a variety of environmental, health and safety regulations. Failure to comply with these regulations may result in administrative, civil and criminal enforcement measures and changes in these regulations could increase our costs or liabilities.

We are subject to a variety of U.S. federal, state, local and international laws and regulations relating to the environment, and worker health and safety. These laws and regulations are complex, change frequently, are becoming increasingly stringent, and the cost of compliance with these requirements can be expected to increase over time. Failure to comply with these laws and regulations may result in administrative, civil and criminal enforcement measures, including assessment of monetary penalties, imposition of remedial requirements and issuance of injunctions as to future compliance. Certain of these laws also may impose joint and several and strict liability for environmental contamination, which may render us liable for remediation costs, natural resource damages and other damages as a result of our conduct that may have been lawful at the time it occurred or the conduct of, or conditions caused by, prior owners or operators or other third parties. In addition, where contamination may be present, it is not uncommon for neighboring land owners and other third parties to file claims for personal injury, property damage and recovery of response costs. Remediation costs and other damages arising as a result of environmental laws and regulations, and costs associated with new information, changes in existing environmental laws and regulations or the adoption of new environmental laws and regulations could be substantial and could negatively impact our financial condition, profitability and results of operations.

We may need to apply for or amend facility permits or licenses from time to time with respect to storm water or wastewater discharges, waste handling, or air emissions relating to manufacturing activities or equipment operations, which subjects us to new or revised permitting conditions. These permits and authorizations may contain numerous compliance requirements, including monitoring and reporting obligations and operational restrictions, such as emission limits, which may be onerous or costly to comply with. In addition, certain of our customer service arrangements may require us to operate, on behalf of a specific customer, petroleum storage units such as underground tanks or pipelines and other regulated units, all of which may impose additional compliance and permitting obligations. Given the large number of facilities in which we operate, and the numerous environmental permits and other authorizations that are applicable to our operations, we may occasionally identify or be notified of technical violations of certain requirements existing in various permits or other authorizations. Occasionally, we have been assessed penalties for our non-compliance, and we could be subject to such penalties in the future.

The modification or interpretation of existing environmental, health and safety laws or regulations, the more vigorous enforcement of existing laws or regulations, or the adoption of new laws or regulations may also negatively impact oil and natural gas exploration and production, gathering and pipeline companies, including our customers, which in turn could have a negative impact on us.

Risks Relating toGlobal climate change is an increased international concern and could increase operating costs or reduce the Spin-offdemand for our products and services.

We may not realize someThere has been an increased focus in the last several years on climate change and the possible role that emissions of greenhouse gases such as carbon dioxide and methane play in climate change. In the U.S., the EPA has begun to regulate greenhouse gas emissions under the federal Clean Air Act and regulatory agencies and legislative bodies in other countries where we operate have adopted greenhouse gas emission reduction programs. The adoption of new or allmore stringent legislation or regulatory programs restricting greenhouse gas emissions could require us to incur higher operating costs or increase the cost of, and thus reduce the benefits we expected to achieve fromdemand for, the hydrocarbon products of our separation from Archrock.customers. These increased costs or reduced demand could have an adverse effect on our business, profitability or results of operations.

The expected benefits fromFurther, some scientists have concluded that increasing greenhouse gas concentrations in the atmosphere may produce physical effects, such as increased severity and frequency of storms, droughts, floods and other climate events. To the extent there are significant changes in the Earth’s climate in the markets we serve or the areas where our separation from Archrock includeassets reside, we could incur increased expenses, our operations could be materially impacted, and demand for our products could fall. Demand for our products may also be adversely affected by conservation plans and efforts undertaken in response to global climate change, including plans developed in connection with the following:

Risks Related to Our Level of Indebtedness

Our outstanding debt obligations could limit our ability to fund future growth and operations and increase our exposure to risk during adverse economic conditions.

At December 31, 2017, we had approximately $375.0 million under our 8.125% senior unsecured notes due 2025 (the “2017 Notes”). We did not have any borrowings under our revolving credit facility as of December 31, 2017. Many factors, including factors beyond our control, may not achieveaffect our ability to make payments on our outstanding indebtedness. These factors include those discussed elsewhere in these Risk Factors and those listed in the anticipated benefits from our separation for a varietyDisclosure Regarding Forward-Looking Statements section included in Part I of reasons.this Annual report.

Our debt and associated commitments could have important adverse consequences. For example, these commitments could:
make it more difficult for us to satisfy our contractual obligations;
increase our vulnerability to general adverse economic and industry conditions;
limit our ability to fund future working capital, capital expenditures, investments, acquisitions or other corporate requirements;
increase our vulnerability to interest rate fluctuations because the interest payments on borrowings under our revolving credit facility are based upon variable interest rates and can adjust based upon our credit statistics;
limit our flexibility in planning for, or reacting to, changes in our business and our industry;
place us at a disadvantage compared to our competitors that have less debt or less restrictive covenants in such debt; and
limit our ability to borrow additional funds in the future.

Covenants in our debt agreements may restrict our ability to operate our business.

Our credit agreement, consisting of a $680.0 million revolving credit facility expiring in November 2020, contains various covenants with which we, mayExterran Energy Solutions, L.P. (“EESLP”), our wholly owned subsidiary, and our respective restricted subsidiaries must comply, including, but not limited to, limitations on the incurrence of indebtedness, investments, liens on assets, repurchasing equity, making distributions, transactions with affiliates, mergers, consolidations, dispositions of assets and other provisions customary in similar types of agreements. Additionally, we are required to maintain certain financial covenant ratios. If we fail to remain in compliance with these restrictions and financial covenants, we would be unsuccessful in executingdefault under our strategy of expandingcredit agreement. In addition, if we experience a material adverse effect on our product sales customer baseassets, liabilities, financial condition, business or operations that, taken as a whole, impact our ability to include competitors of Archrock because these prospective customers may have long-standing relationships with existing providers of similar products or services. The availability of sharesperform our obligations under our credit agreement, this could lead to a default. A default under one of our common stock for use as consideration for acquisitions also will not ensure that we willdebt agreements might trigger cross-default provisions under our other debt agreement, which would accelerate our obligation to repay our indebtedness under those agreements. If the repayment obligations on any of our indebtedness were to be able to successfully pursue acquisitions or that any acquisitions will be successful. Moreover, even with equity compensation tied to our businessaccelerated, we may not be able to attractrepay the debt or refinance the debt on acceptable terms, and retain employees as desired. We also may not fully realize the anticipated benefits from our separation if any of the matters identified as risks in this “Risk Factors” section were to occur. If we do not realize the anticipated benefits from our separation for any reason, our business mayfinancial position would be materially adversely affected.

Our historical combined financial information may not be representative of the results we would have achieved as a stand-alone public company and may not be a reliable indicator of our future results.

The historical combined financial information for periods prior to the Spin-off that we have included in this annual report has been derived from Archrock’s accounting records and may not necessarily reflect what our financial position, results of operations or cash flows would have been had we been an independent, stand-alone entity during the periods presented or those that we will achieve in the future. Archrock did not account for us, and we were not operated, as a separate, stand-alone company for the historical periods presented. The costs and expenses reflected in our historical financial information include an allocation for certain functions historically provided by Archrock, including expense allocations for: (1) certain functions historically provided by Archrock, including, but not limited to finance, legal, risk management, tax, treasury, information technology, human resources, and certain other shared services, (2) certain employee benefits and incentives and (3) share-based compensation, that may be different from the comparable expenses that we would have incurred had we operated as a stand-alone company. These expenses have been allocated to us on the basis of direct usage when identifiable, with the remainder allocated based on estimated time spent by Archrock personnel, a pro-rata basis of revenues, headcount or other relevant measures of our business and Archrock and its subsidiaries. We have not adjusted our historical combined financial information to reflect changes that have occurred in our cost structure and operations as a result of the Spin-off, including increased costs associated with an independent board of directors, SEC reporting and the requirements of the NYSE. Therefore, our historical financial information may not necessarily be indicative of what our financial position, results of operations or cash flows will be in the future.

Our costs will increase as a result of operating as a public company, and our management is required to devote substantial time to complying with public company regulations.

We have historically operated our businesses as part of a public company. As a stand-alone public company, we now incur additional legal, accounting, compliance and other expenses that we have not incurred historically. As a result of the Spin-off, we are obligated to file with the SEC annual and quarterly information and other reports that are specified in Section 13 and other sections of the Exchange Act. We are also required to ensure that we have the ability to prepare financial statements that are fully compliant with all SEC reporting requirements on a timely basis. In addition, we are also subject to other reporting and corporate governance requirements, including certain requirements of the NYSE, and certain provisions of the Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley”), and the regulations promulgated thereunder, which will impose significant compliance obligations upon us.

We are committed to maintaining high standards of corporate governance and public disclosure, and our efforts to comply with evolving laws, regulations and standards in this regard are likely to result in increased administrative expenses and a diversion of management’s time and attention from revenue-generating activities to compliance activities. These changes will require a significant commitment of our management and resources. We may not be successful in implementing these requirements and implementing them could materially adversely affect our business, results of operations and financial condition. In addition, if we fail to implement the requirements with respect to our internal accounting and audit functions, our ability to report our operating results on a timely and accurate basis could be impaired. If we do not implement such requirements in a timely manner or with adequate compliance, we might be subject to sanctions or investigation by regulatory authorities, such as the SEC or the NYSE. Any such action could harm our reputation and the confidence of investors and customers in our company and could materially adversely affect our business and cause our share price to fall.


22



Our accounting and other management systems and resources may not be adequately prepared to meet the financial reporting and other requirements to which we are subject and may strain our resources.

Our businesses have historically been operated as part of Archrock, and we were not subject to separate reporting requirements prior to the Spin-off. Following the Spin-off, we utilize our own resources and personnel to meet reporting and other obligations under the Exchange Act, including the requirements of Section 404 of Sarbanes-Oxley, which will require, beginning with the filing of our Annual Report on Form 10-K for the year ending December 31, 2016, annual management assessments of the effectiveness of our internal control over financial reporting and a report by our independent registered public accounting firm expressing an opinion on the effectiveness of our internal control over financial reporting. In addition, we are required to file periodic reports with the SEC under the Exchange Act. These obligations will place significant demands on our management and administrative and operational resources, including accounting resources.

To comply with these requirements, we anticipate that we may need to upgrade our systems, including information technology, implement additional financial and management controls, reporting systems and procedures and hire certain additional accounting and finance personnel. We expect to incur additional annual expenses related to these steps and, among other things, directors and officers liability insurance, director fees, SEC reporting, transfer agent fees, increased auditing and legal fees and similar expenses, which expenses may be significant. If we are unable to upgrade our financial and management controls, reporting systems, information technology and procedures in a timely and effective fashion, our ability to comply with our financial reporting requirements and other rules that apply to reporting companies under the Exchange Act could be impaired. Any failure to achieve and maintain effective internal controls could have an adverse effect on our business, financial condition and results of operations.

We have identified material weaknesses in our internal control over financial reporting before and after the Spin-off that, if not remediated, could result in additional material misstatements in our financial statements.

As described in “Part II, Item 9A — Controls and Procedures,” management has identified and evaluated control deficiencies that gave rise to the accounting errors related to Belleli EPC projects within our product sales segment and non-income-based tax receivables in Brazil, and has concluded that those deficiencies represent material weaknesses in our internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. As a result of these material weaknesses, management has concluded that we did not maintain effective internal control over financial reporting or effective disclosure controls and procedures before the Spin-off and as of December 31, 2015.

We are2017, we were in the process of implementing a remediation plan to address these material weaknesses. Ifcompliance with all financial covenants under our remediation efforts are insufficient or not completed in a timely manner, or if additional material weaknesses in our internal control over financial reporting are identified or occur in the future, our financial statements may contain material misstatements and we could be required to restate our financial results, which could materially and adversely affect our business, results of operations and financial condition, restrict our ability to access the capital markets, require us to expend significant resources to correct the material weaknesses, subject us to fines, penalties or judgments, harm our reputation or otherwise cause a decline in investor confidence.credit agreement.

As a result of the Spin-off, we and Archrock are subject to certain noncompetition restrictions, which may limita covenant restriction included in our ability to grow our business.

In connection with the completioncredit agreement, $585.2 million of the Spin-off, we entered into a separation and distribution agreement with Archrock that contains certain noncompetition provisions addressing restrictions for a limited period$640.3 million of time after the Spin-off on our ability to provide contract operations and aftermarket services in the U.S. and on Archrock’s ability to provide contract operations and aftermarket services outside of the U.S. and product sales to customers worldwide, subject to certain exceptions. These restrictions limit our ability to attract new contract operations and aftermarket services customers in the U.S., which will limit our ability to grow our business.

In addition, if we are unable to enforce the limitations on Archrock’s ability to provide certain contract operations, aftermarket services and product sales, we may lose prospective customers to Archrock, which could cause our results of operations and cash flows to suffer.


23



We and Archrock provide one another with certain services under the transition services agreement that may require us to divert resources from our business, which in turn may negatively impact our business, financial condition and results of operations.

In connection with the completion of the Spin-off, we and Archrock entered into a transition services agreement under which each party will compensate the other for the provision of various administrative services and assets to such other party for specified periods beginning on the Spin-off date. The personnel performing services for Archrock under the transition services agreement are employees and/or independent contractors of ours. In the course of performing our obligations under the transition services agreements, we will allocate certain of our resources, including assets, facilities, equipment and the time and attention of our management and personnel for the benefit of Archrock’s business and not ours, which may negatively impact our business, financial condition and results of operations.

Archrock provides installation, start-up, commissioning and other services to us or our customers on our behalf.

Historically, we have had access to field technicians employed by Archrock to perform the installation and other services we require. In certain cases, we now rely on some of Archrock’s technicians to provide installation, start-up, commissioning and other services to us or our customers on our behalf pursuant to the services agreement we entered into with Archrock on arm’s length terms in connection with the completion of the Spin-off. If Archrock is unable to satisfy its obligations to us or on our behalfundrawn capacity under our commercial agreements with our customersrevolving credit facility was available for any reason, we may be unable to provide services required by our customers who purchase our products and therefore our sales and revenues may decline and our financial condition, resultsadditional borrowings as of operations and cash flows may be negatively impacted. In addition, should the services provided by Archrock not meet our standards or the standards of our customers, we may be subject to claims by our customers relating to damages incurred in connection with any such substandard performance. These claims could cause increased expenses and harm our reputation, which could negatively impact our financial condition, results of operations and cash flows. In addition, we provide certain engineering, start-up, commissioning, preservation and other services to Archrock or its customers on behalf of Archrock pursuant to a reciprocal services agreement we entered into with Archrock. The provision of such services under the reciprocal services agreement requires us to allocate certain of our resources, including assets, facilities, equipment and the time and attention of our management and personnel for the benefit of Archrock’s business and not ours, which may negatively impact our business, financial condition and results of operations.

We provide Archrock and Archrock Partners with certain manufactured products, including compressors, and we depend on Archrock and Archrock Partners for a significant amount of our product sales revenues.

As a result of the Spin-off, Archrock and Archrock Partners are among our largest customers and are expected to generate significant product sales revenues for us. Therefore, we are indirectly subject to the operational and business risks of Archrock and Archrock Partners. If either Archrock or Archrock Partners is unable to satisfy its obligations or reduces its demand under our commercial agreements for any reason, our revenues would decline and our financial condition, results of operations and cash flows could be adversely affected. Further, we have no control over Archrock or Archrock Partners, and either Archrock or Archrock Partners may elect to pursue a business strategy that does not favor us or our business.

Certain members of our board and management could have conflicts of interest because of their prior relationships with Archrock.

Following the Spin-off, certain members of our board and management may own shares of common stock of Archrock and/or hold equity awards covering shares of common stock of Archrock because of their prior relationships with Archrock. This share and equity award ownership could create, or appear to create, potential conflicts of interest when our directors and executive officers are faced with decisions that could have different implications for our company and Archrock.

We may increase our debt or raise additional capital in the future, which could affect our financial condition, may decrease our profitability or could dilute our shareholders.

We may increase our debt or raise additional capital in the future, subject to restrictions in our credit agreement.debt agreements. If our cash flow from operations is less than we anticipate, or if our cash requirements are more than we expect, we may require more financing. However, debt or equity financing may not be available to us on terms acceptable to us, if at all. If we incur additional debt or raise equity through the issuance of preferred stock, the terms of the debt or preferred stock issued may give the holders rights, preferences and privileges senior to those of holders of our common stock, particularly in the event of liquidation. The terms of the debt may also impose additional and more stringent restrictions on our operations than we currently have. If we raise funds through the issuance of additional equity, our shareholders’ ownership in us would be diluted. If we are unable to raise additional capital when needed, it could affect our financial health, which could negatively affect our shareholders.

Risks Related to the Spin-off

As a result of the Spin-off, we and Archrock are subject to certain noncompetition restrictions, which may limit our ability to grow our business.

In connection with the completion of the Spin-off, we entered into a separation and distribution agreement with Archrock that contains certain noncompetition provisions addressing restrictions on our ability to provide compression contract operations and aftermarket services in the U.S. and on Archrock’s ability to provide compression contract operations and aftermarket services outside of the U.S. and product sales to customers worldwide that expire on November 3, 2018, subject to certain exceptions. These restrictions limit our ability to attract new compression contract operations and aftermarket services customers in the U.S., which will limit our ability to grow our business.

In addition, if we are unable to enforce the limitations on Archrock’s ability to provide certain contract operations, aftermarket services and product sales, we may lose prospective customers to Archrock, which could affect our financial condition, results of operations and cash flows to suffer.

We provide Archrock and its affiliates with certain manufactured products and we depend on Archrock and its affiliates for a significant amount of our product sales revenues.

Archrock and its affiliates are among our largest customers. During the year ended December 31, 2017, Archrock and its affiliates accounted for approximately 12% of our total revenue. Therefore, we are indirectly subject to the operational and business risks of Archrock and its affiliates. If Archrock and its affiliates are unable to satisfy its obligations or reduces its demand for any reason, our revenues would decline and our financial condition, results of operations and cash flows could be adversely affected. Further, we have no control over Archrock and its affiliates, and Archrock and its affiliates may elect to pursue a business strategy that does not favor us or our business.

We are subject to continuing contingent tax liabilities of Archrock.

Certain tax liabilities of Archrock may become our obligations. Under the Code and the related rules and regulations, each corporation that was a member of the Archrock consolidated U.S. federal income tax reporting group during any taxable period or portion of any taxable period ending on or before the effective time of the Spin-off is jointly and severally liable for the U.S. federal income tax liability of the entire Archrock consolidated tax reporting group for that taxable period. In connection with the Spin-off, we entered into a tax matters agreement with Archrock that allocates the responsibility for prior period taxes of the Archrock consolidated tax reporting group between us and Archrock. If Archrock is unable to pay any prior period taxes for which it is responsible, we could be required to pay the entire amount of such taxes.

The tax treatment of the Spin-off is subject to uncertainty. If the Spin-off does not qualify as a transaction that is tax-free for U.S. federal income tax purposes, we, Archrock and our shareholders could be subject to significant tax liability and, in certain circumstances, we could be required to indemnify Archrock for material taxes pursuant to indemnification obligations under the tax matters agreement.

If the Spin-off is determined to be taxable for U.S. federal income tax purposes, then we, Archrock and/or our shareholders could be subject to significant tax liability. Archrock obtained an opinion of Latham & Watkins LLP substantially to the effect that, for U.S. federal income tax purposes, the Spin-off should qualify as a reorganization under Sections 355 and 368(a)(1)(D) of the Code, subject to certain qualifications and limitations. Accordingly, for U.S. federal income tax purposes, Archrock should not recognize any material gain or loss and our shareholders generally should recognize no gain or loss or include any amount in taxable income (other than with respect to cash received in lieu of fractional shares) as a result of the Spin-off.

Notwithstanding the opinion, the Internal Revenue Service (the “IRS”) could determine on audit that the Spin-off should be treated as a taxable transaction if it determines that any of the facts, assumptions, representations or undertakings we or Archrock has made is not correct or has been violated, or that the Spin-off should be taxable for other reasons, including as a result of a significant change in stock or asset ownership after the Spin-off. If the Spin-off ultimately is determined to be taxable, the Spin-off could be treated as a taxable dividend or capital gain to shareholders for U.S. federal income tax purposes, and shareholders could incur significant U.S. federal income tax liabilities. In addition, Archrock would recognize gain in an amount equal to the excess of the fair market value of shares of our common stock distributed to Archrock shareholders on the Spin-off date over Archrock’s tax basis in such shares of our common stock, and Archrock could incur other significant U.S. federal income tax liabilities.

Under the terms of the tax matters agreement that we entered into with Archrock in connection with the Spin-off, if the Spin-off were determined to be taxable, we may be responsible for all taxes imposed on Archrock as a result thereof if such determination was the result of actions taken after the Spin-off by or in respect of us, any of our affiliates or our shareholders and we may be responsible for 50% of such taxes imposed on Archrock as a result thereof if such determination was not the result of actions taken by us or Archrock. Our obligations under the tax matters agreement are not limited in amount or subject to any cap. Further, even if we are not responsible for tax liabilities of Archrock and its subsidiaries under the tax matters agreement, we nonetheless could be liable under applicable tax law for such liabilities if Archrock were to fail to pay them. If we are required to pay any liabilities under the circumstances set forth in the tax matters agreement or pursuant to applicable tax law, the amounts may be significant.


25



We might not be able to engage in desirable strategic transactions and equity issuances because of certain restrictions relating to requirements for a tax-free Spin-off.

Our ability to engage in significant equity transactions could be limited or restricted in order to preserve, for U.S. federal income tax purposes, the tax-free nature of the Spin-off. Even if the Spin-off otherwise qualifies for tax-free treatment under Section 355 of the Code, it may result in corporate-level taxable gain to Archrock under Section 355(e) of the Code if there is a 50% or greater change in ownership, by vote or value, of shares of our stock, Archrock’s stock or the stock of a successor of either occurring as part of a plan or series of related transactions that includes the Spin-off. Any acquisitions or issuances of our stock or Archrock’s stock within two years after the Spin-off are generally presumed to be part of such a plan, although we or Archrock may be able to rebut that presumption.

Under the tax matters agreement that we entered into with Archrock, we are prohibited from taking or failing to take any action that prevents the Spin-off from being tax-free. Further, during the two-year period following the Spin-off, without obtaining the consent of Archrock, a private letter ruling from the IRS or an unqualified opinion of a nationally recognized law firm, we may be prohibited from taking certain specified actions that could impact the treatment of the Spin-off.

These restrictions may limit our ability to pursue strategic transactions or engage in new business or other transactions that may maximize the value of our business. Moreover, the tax matters agreement also provides that we are responsible for any taxes imposed on Archrock or any of its affiliates as a result of the failure of the Spin-off to qualify for favorable treatment under the Code if such failure is attributable to certain actions taken after the Spin-off by or in respect of us, any of our affiliates or our shareholders.

Our prior and continuing relationship with Archrock exposes us to risks attributable to businesses of Archrock.

Archrock is obligated to indemnify us for losses that third parties may seek to impose upon us or our affiliates for liabilities relating to the business of Archrock that are incurred through a breach of the separation and distribution agreement or any ancillary agreement by Archrock or its affiliates other than us, or losses that are attributable to Archrock in connection with the Spin-off or are not expressly assumed by us under our agreements with Archrock. Any claims made against us that are properly attributable to Archrock in accordance with these arrangements would require us to exercise our rights under our agreements with Archrock to obtain payment from Archrock. We are exposed to the risk that, in these circumstances, Archrock cannot, or will not, make the required payment.


20



In connection with our separation from Archrock, Archrock will indemnify us for certain liabilities, and we will indemnify Archrock for certain liabilities. If we are required to act on these indemnities to Archrock, we may need to divert cash to meet those obligations, and our financial results could be negatively impacted. In the case of Archrock’s indemnity, there can be no assurance that the indemnity will be sufficient to insure us against the full amount of such liabilities, or as to Archrock’s ability to satisfy its indemnification obligations.

Pursuant to the separation and distribution agreement and other agreements with Archrock, Archrock has agreed to indemnify us for certain liabilities, and we have agreed to indemnify Archrock for certain liabilities, in each case for uncapped amounts, as discussed further in our Registration Statement. Under the separation and distribution agreement, we and Archrock will generally release the other party from all claims arising prior to the Spin-off that relate to the other party’s business, subject to certain exceptions. Also pursuant to the separation and distribution agreement, we have agreed to use our commercially reasonable efforts to remove Archrock as a party to certain of our contracts with third parties, which may result in a renegotiation of such contracts on terms that are less favorable to us.parties. In the event that Archrock remains as a party, we expect to indemnify Archrock for any liabilities relating to such contracts. Indemnities that we may be required to provide Archrock will not be subject to any cap, may be significant and could negatively impact our business, particularly indemnities relating to our actions that could impact the tax-free nature of the Spin-off.

With respect to Archrock’s agreement to indemnify us, there can be no assurance that the indemnity from Archrock will be sufficient to protect us against the full amount of such liabilities, or that Archrock will be able to fully satisfy its indemnification obligations. Moreover, even if we ultimately succeed in recovering from Archrock any amounts for which we are held liable, we may be temporarily required to bear these losses ourselves. Each of these risks could negatively affect our business, cash flows, results of operations and financial condition.


26



The Spin-off may expose usRisks Related to potential liabilities arising out of state and federal fraudulent conveyance laws and legal dividend requirements.

The Spin-off is subject to review under various state and federal fraudulent conveyance laws. Under these laws, if a court in a lawsuit by an unpaid creditor or an entity vested with the power of such creditor (including without limitation a trustee or debtor-in-possession in a bankruptcy by us or Archrock or any of our respective subsidiaries) were to determine that Archrock or any of its subsidiaries did not receive fair consideration or reasonably equivalent value for distributing our common stock or taking other action as part of the Spin-off, or that we or any of our subsidiaries did not receive fair consideration or reasonably equivalent value for incurring indebtedness, including the borrowings incurred by us under the new credit facility in connection with the Spin-off, transferring assets or taking other action as part of the Spin-off and, at the time of such action, we, Archrock or any of our respective subsidiaries (i) was insolvent or would be rendered insolvent, (ii) lacked reasonably sufficient capital to carry on its business and all business in which it intended to engage or (iii) intended to incur, or believed it would incur, debts beyond its ability to repay such debts as they would mature, then such court could void the Spin-off as a constructive fraudulent transfer. If such court made this determination, the court could impose a number of different remedies, including without limitation, voiding our liens and claims against Archrock, or providing Archrock with a claim for money damages against us in an amount equal to the difference between the consideration received by Archrock and the fair market value of our company at the time of the Spin-off.

The measure of insolvency for purposes of the fraudulent conveyance laws will vary depending on which jurisdiction’s law is applied. Generally, however, an entity would be considered insolvent if the present fair saleable value of its assets is less than (i) the amount of its liabilities (including contingent liabilities) or (ii) the amount that will be required to pay its probable liabilities on its existing debts as they become absolute and mature. No assurance can be given as to what standard a court would apply to determine insolvency or that a court would determine that we, Archrock or any of our respective subsidiaries were solvent at the time of or after giving effect to the Spin-off, including the distribution of our common stock.

Under the separation and distribution agreement, each of Archrock and we are responsible for the debts, liabilities and other obligations related to the business or businesses which it owns and operates following the consummation of the Spin-off. Although we do not expect to be liable for any such obligations not expressly assumed by us pursuant to the separation and distribution agreement, it is possible that a court would disregard the allocation agreed to between the parties, and require that we assume responsibility for obligations allocated to Archrock, particularly if Archrock were to refuse or were unable to pay or perform the subject allocated obligations.

Risks Relating to Ownership of Our Common Stock

The market price and trading volume of our common stock may be volatile.

The market price of our stock may be influenced by many factors, some of which are beyond our control, including the following:

the inability to meet the financial estimates of analysts who follow our common stock;

strategic actions by us or our competitors;

announcements by us or our competitors of significant contracts, acquisitions, joint marketing relationships, joint ventures or capital commitments;

variations in our quarterly operating results and those of our competitors;

general economic and stock market conditions;

risks relating to our business and our industry, including those discussed above;

changes in conditions or trends in our industry, markets or customers;

cyber-attacks or terrorist acts;

future sales of our common stock or other securities;

material weaknesses in our internal control over financial reporting; and

27




investor perceptions of the investment opportunity associated with our common stock relative to other investment alternatives.

These broad market and industry factors may materially reduce the market price of our common stock, regardless of our operating performance. In addition, price volatility may be greater if the public float and trading volume of our common stock is low.

We have not been in compliance with the New York Stock Exchange’s requirements for continued listing and as a result our common stock may be delisted from trading, which would have a material effect on us and our stockholders.
21


We have been delinquent in the filing of our periodic reports with the SEC, as a result of which we are not in compliance with the rules of the New York Stock Exchange (“NYSE”). By filing our quarterly reports on Form 10-Q for the quarters ended March 31, 2016, June 30, 2016 and September 30, 2016, which we intend to file shortly, we currently believe that we will have adequately remediated our current non-compliance with the NYSE’s rules. However, there can be no assurance that the NYSE will concur that we have remediated our non-compliance, in which case our common stock could be subject to delisting. In addition, we have delayed our annual meeting of stockholders as a result of the restatement. To the extent we cannot hold our annual meeting before the end of 2017, our stock may again be subject to delisting from trading on the NYSE. If our common stock is delisted, there can be no assurance as to whether or when our common stock would again be listed for trading on NYSE or any other exchange. The market price of our shares will also likely decline and become more volatile if our common stock is delisted, and our stockholders may find that their ability to trade in our stock will be adversely affected. Furthermore, institutions whose charters do not allow them to hold securities in unlisted companies might sell our shares, which could have a further adverse effect on the price of our stock.

The trading market for our common stock and our stock price is influenced from coverage by, and the recommendations of, securities or industry analysts, and unfavorable or insufficient coverage could cause our stock price to decline.

The trading market for our common stock is influenced by the research and reports that industry or securities analysts publish about us or our business. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline. In addition, if we fail to meet the expectations of these analysts or if one or more of these analysts change their recommendations regarding our stock or our business, our stock price may decline.

Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to choose the judicial forum for disputes with us or our directors, officers or other employees.

Our amended and restated certificate of incorporation provides that, unless we consent in writing to the selection of an alternate forum, the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, our amended and restated certificate of incorporation or our bylaws, in each case, as amended from time to time, or (iv) any action asserting a claim governed by the internal affairs doctrine, shall be the Court of Chancery of the State of Delaware, in all cases subject to the court’s having personal jurisdiction over the indispensable parties named as defendants. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock is deemed to have received notice of and consented to the foregoing provision. This forum selection provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable or cost-effective for disputes with us or our directors, officers or other employees, which may discourage such lawsuits against us and our directors, officers and employees.

Item 3.  Legal Proceedings
 
In the ordinary course of business, we are involved in various pending or threatened legal actions. While management is unable to predict the ultimate outcome of these actions, it believes that any ultimate liability arising from any of these actions will not have a material adverse effect on our financial position, results of operations or cash flows. However, because of the inherent uncertainty of litigation and arbitration proceedings, we cannot provide assurance that the resolution of any particular claim or proceeding to which we are a party will not have a material adverse effect on our financial position, results of operations or cash flows.

Contemporaneously with filing the Form 8-K on April 26, 2016, we self-reported the errors and possible irregularities at Belleli EPC to the SEC. Since then, we have been cooperating with the SEC in its investigation of this matter, includingwhich has included responding to a subpoena for documents related to the restatement and of our compliance with the FCPA, which arewere also being provided to the Department of Justice at its request. The SEC staff has notified us that they have concluded their investigation concerning our compliance with the FCPA and that they do not intend to recommend an enforcement action concerning our compliance with the FCPA. The DOJ has similarly informed us that it does not intend to proceed with any further investigation or enforcement. The SEC’s investigation related requests into the circumstances giving rise to the restatement is continuing, and we are presently unable to predict the duration, scope or results or whether the SEC subpoena pertain to our policies and procedures, information about our third-party sales agents, and documents related to historical internal investigations completed prior to November 2015.will commence any legal action.

For information regarding the background of the restatement see the Explanatory Note immediately preceding the Table of Contents. See Note 3 to the Financial Statements for a summary of the effects of the restatement adjustments on our financial statements as of December 31, 2015 and 2014 and for the years ended December 31, 2015, 2014 and 2013. The effects of the restatement on balance sheet data as of December 31, 2013, 2012 and 2011 and statement of operations data for the years ended December 31, 2012 and 2011 are set forth below.

(2)For the periods prior to November 3, 2015, the average number of common shares outstanding used to calculate basic and diluted net income (loss) from continuing operations per common share was based on 34,286,267 shares of our common stock that were distributed by Archrock in the Spin-off on November 3, 2015.

GrossTotal gross margin and EBITDA, as adjusted, are non-GAAP financial measures. GrossTotal gross margin and EBITDA, as adjusted, are defined, reconciled to income (loss) before income taxes and net income (loss), respectively, and discussed further below under “Non-GAAP Financial Measures.”

(3)
Growth capital expenditures are made to expand or to replace partially or fully depreciated assets or to expand the operating capacity or revenue generating capabilities of existing or new assets, whether through construction, acquisition or modification. The majority of our growth capital expenditures are related to the acquisition cost of new compressor units and processing and treating equipment that we add to our contract operations fleet and installation costs on integrated projects. In addition, growth capital expenditures can include the upgrading of major components on an existing compressor unit where the current configuration of the compressor unit is no longer in demand and the compressor unit is not likely to return to an operating status without the capital expenditures. These latter expenditures substantially modify the operating parameters of the compressor unit such that it can be used in applications for which it previously was not suited.

(5)
(4)
Maintenance capital expenditures are made to maintain the existing operating capacity of our assets and related cash flows further extending the useful lives of the assets. Maintenance capital expenditures are related to major overhauls of significant components of a compressor unit, such as the engine, compressor and cooler, that return the components to a “like new” condition, but do not modify the applications for which the compressor unit was designed.

In the fourth quarter of 2015, we elected early adoption, with retrospective application, of Accounting Standards Update No. 2015-17, Balance Sheet Classification of Deferred Taxes, which simplifies the presentation of deferred taxes by requiring deferred tax assets and liabilities be classified as noncurrent on theAmounts include balance sheet. Accordingly, periods prior to December 31, 2015 were reclassified to conform to the presentation within this update.sheet data for discontinued operations.

Pursuant to the separation and distribution agreement with Archrock and certain of our and Archrock’s respective affiliates, on November 3, 2015, we transferred $532.6 million of net proceeds from borrowings under our credit facility to Archrock to allow it to repay a portion of its indebtedness in connection with the Spin-off.

Non-GAAP Financial Measures

We define gross margin as total revenue less cost of sales (excluding depreciation and amortization expense). GrossWe evaluate the performance of each of our segments based on gross margin. Total gross margin is included as a supplemental disclosure because it is a primary measure used by our management to evaluate the results of revenue and cost of sales (excluding depreciation and amortization expense), which are key components of our operations. We believe gross margin is important because it focuses on the current operating performance of our operations and excludes the impact of the prior historical costs of the assets acquired or constructed that are utilized in those operations, the indirect costs associated with our selling, general and administrative (“SG&A”) activities, the impact of our financing methods and income taxes. Depreciation and amortization expense may not accurately reflect the costs required to maintain and replenish the operational usage of our assets and therefore may not portray the costs from current operating activity. As an indicator of our operating performance, total gross margin should not be considered an alternative to, or more meaningful than, net income (loss) before income taxes as determined in accordance with generally accepted accounting principles generally accepted in the U.S. (“GAAP”). Our gross margin may not be comparable to a similarly titled measure of another company because other entities may not calculate gross margin in the same manner.

GrossTotal gross margin has certain material limitations associated with its use as compared to net income (loss). before income taxes. These limitations are primarily due to the exclusion of interest expense, depreciation and amortization expense, SG&A expense, impairments and restructuring and other charges. Each of these excluded expenses is material to our statements of operations. Because we intend to finance a portion of our operations through borrowings, interest expense is a necessary element of our costs and our ability to generate revenue. Additionally, because we use capital assets, depreciation expense is a necessary element of our costs and our ability to generate revenue, and SG&A expenses are necessary to support our operations and required corporate activities. To compensate for these limitations, management uses thistotal gross margin, a non-GAAP measure, as a supplemental measure to other GAAP results to provide a more complete understanding of our performance.

We define EBITDA, as adjusted, as net income (loss) excluding income (loss) from discontinued operations (net of tax), cumulative effect of accounting changes (net of tax), income taxes, interest expense (including debt extinguishment costs), depreciation and amortization expense, impairment charges, restructuring and other charges, non-cash gains or losses from foreign currency exchange rate changes recorded on intercompany obligations, expensed acquisition costs and other items. We believe EBITDA, as adjusted, is an important measure of operating performance because it allows management, investors and others to evaluate and compare our core operating results from period to period by removing the impact of our capital structure (interest expense from our outstanding debt), asset base (depreciation and amortization), our subsidiaries’ capital structure (non-cash gains or losses from foreign currency exchange rate changes on intercompany obligations), tax consequences, impairment charges, restructuring and other charges, expensed acquisition costs and other items. Management uses EBITDA, as adjusted, as a supplemental measure to review current period operating performance, comparability measures and performance measures for period to period comparisons. In addition, the compensation committee has used EBITDA, as adjusted, in evaluating the performance of the Company and management and in evaluating certain components of executive compensation, including performance-based annual incentive programs. Our EBITDA, as adjusted, may not be comparable to a similarly titled measure of another company because other entities may not calculate EBITDA in the same manner.

37




EBITDA, as adjusted, is not a measure of financial performance under GAAP and should not be considered in isolation or as an alternative to net income (loss), cash flows from operating activities andor any other measuresmeasure determined in accordance with GAAP. Items excluded from EBITDA, as adjusted, are significant and necessary components to the operation of our business and therefore, EBITDA, as adjusted, should only be used as a supplemental measure of our operating performance.

Spin-off

On November 3, 2015, Archrock, Inc. (named Exterran Holdings, Inc. prior to November 3, 2015) (“Archrock”) completed the spin-off (the “Spin-off”) of its international contract operations, international aftermarket services (the international contract operations and international aftermarket services businesses combined are referred to as the “international services businesses” and include such activities conducted outside of the United States of America (“U.S.”)) and global fabrication businesses into an independent, publicly traded company (“Exterran Corporation,” “our,” “we” or “us”). We refer to the global fabrication business previously operated by Archrock as our product sales business. To effect the Spin-off, on November 3, 2015, Archrock distributed, on a pro rata basis, all of our shares of common stock to its stockholders of record as of October 27, 2015 (the “Record Date”). Archrock shareholders received one share of Exterran Corporation common stock for every two shares of Archrock common stock held at the close of business on the Record Date. Pursuant to the separation and distribution agreement with Archrock and certain of our and Archrock’s respective affiliates, on November 3, 2015, we transferred cash of $532.6 million to Archrock. Following the completion of the Spin-off, we and Archrock arebecame and continue to be independent, publicly traded companies with separate boards of directors and management.

We refer to the consolidated and combined financial statements collectively as “financial statements,” and individually as “balance sheets,” “statements of operations,” “statements of comprehensive income (loss),” “statements of stockholders’ equity” and “statements of cash flows” herein.

Industry Conditions and Trends

Our business environment and corresponding operating results are affected by the level of energy industry spending for the exploration, development and production of oil and natural gas reserves. Spending by oil and natural gas exploration and production companies is dependent upon these companies’ forecasts regarding the expected future supply, demand and pricing of oil and natural gas products as well as their estimates of risk-adjusted costs to find, develop and produce reserves. Although we believe our contract operations business, and to a lesser extent our product sales business, is typically less impacted by short-term commodity prices than certain other energy products and service providers, changes in oil and natural gas exploration and production spending normally result in changes in demand for our products and services.

Natural gas consumptionsignificant declines in commodity prices, which resulted in reduced investment on the U.S. for the twelve months ended November 30, 2015 increased by approximately 2% comparedpart of our customers, commodity prices started to the twelve months ended November 30, 2014. The U.S. Energy Information Administration (“EIA”) forecasts that total U.S. natural gas consumption will increase by 1.4% in 2016 compared to 2015 and increase by an average of 0.7% per year thereafter until 2040. The EIA estimates that the U.S. natural gas consumption level will be approximately 30 trillion cubic feet in 2040, or 16% of the projected worldwide total of approximately 185 trillion cubic feet. The EIA forecasts that total worldwide natural gas consumption will increase by an average of 1.7% per year between 2016 and 2040.

Natural gas marketed production in the U.S. for the twelve months ended November 30, 2015 increased by approximately 6% compared to the twelve months ended November 30, 2014. The EIA forecasts that total U.S. natural gas marketed production will increase by 0.7% in 2016 compared to 2015 and U.S. natural gas production will increase by an average of 1.5% per year thereafter until 2040. The EIA estimates that the U.S. natural gas production level will be approximately 33 trillion cubic feet in 2040, or 18% of the projected worldwide total of approximately 187 trillion cubic feet. The EIA forecasts that total worldwide natural gas production will increase by an average of 1.7% per year between 2016 and 2040.

Global oil and U.S. natural gas prices have declined significantly since the third quarter of 2014, which led to declinesincreased customer spending in 2017, primarily in North America. As such, we experienced higher activity levels in North America, which resulted in higher demand for gas processing and treating plants and compression equipment within our product sales business. Oil prices rose largely due to OPEC’s agreement to limit production, which incentivized U.S. producers to increase their investments in shale oil. International activity was not meaningfully impacted by higher commodity prices primarily due to uncertainty regarding oil and worldwidenatural gas supply and demand fundamentals as well as concerns over the effectiveness of the OPEC-led production cuts.

Industry observers anticipate that commodity prices and customer spending should continue to increase in 2018 due to the predicted strong global demand for hydrocarbons, including increased demand for liquefied natural gas. Geographically, North America is expected to see the largest increase in industry spending with international markets anticipated to grow for the first time in four years, albeit at modest levels.

However, customer cash flows and returns on capital could drive customer investment priorities. Industry observers believe shareholders are encouraging management teams of energy producers to focus operational and compensation strategies on returns and cash flow generation rather than solely on production growth. To accomplish these strategies, industry observers believe that energy producers would need to better prioritize capital spending such that cash required for drilling activity in 2015. In 2016, giventheir investments would not exceed cash generated from their operating cash flows. This could impact resource allocation and ultimately the current market environment, we expect continued declines in worldwideamount of new projects and capital spending for drilling activity.by our customers.

Our Performance Trends and Outlook

Our revenue, earnings and financial position are affected by, among other things, market conditions that impact demand and pricing for natural gas compression and oil and natural gas production and processing and our customers’ decisions among usingto use our products and services, usinguse our competitors’ products and services or owningown and operatingoperate the equipment themselves.

Low commodity prices in 2015 and the first half of 2016 led to reduced energy related capital spending in those years by our customers in North America have been volatile. For example,America. Customer spending and investments in equipment increased in 2017 as commodity prices, primarily oil prices, rebounded from their cyclical lows, leading to a sharp increase in bookings during the year. The Henry Hub spot price for natural gas was $2.28$3.69 per MMBtu at December 31, 2015,2017, which was approximately 27%1% lower and 47% lower62% higher than prices at December 31, 20142016 and 2013,2015, respectively, and the U.S. natural gas liquid composite price was approximately $4.72$8.03 per MMBtu for the month of November 2015,2017, which was approximately 16%21% and 56% lower90% higher than prices for the months of December 20142016 and 2013,2015, respectively. These lower prices led to reduced drilling of gas wells in North America in 2015. In addition, the West Texas Intermediate crude oil spot price as of December 31, 20152017 was approximately 31%12% and 62% lower63% higher than prices at December 31, 20142016 and 2013, respectively, which led to reduced drilling of oil wells in 2015. More recently, West Texas Intermediate crude oil prices continued to decline during 2016, represented by a spot price decrease of 9% at January 31, 2016 compared to December 31, 2015.2015, respectively. During periods of lower oil or natural gas prices, our customers typically decrease their capital expenditures, which generally results in lower activity levels. As a result of the low oil and natural gas price environment in North America, our customers have sought to reduce their capital and operating expenditure requirements, and as a result, the demand and pricing for the equipment we manufacture in North America have been adversely impacted. Third party booking activity levels for our manufactured products in North America during the year ended December 31, 20152017 were $390.5$829.8 million, which represents a declinean increase of approximately 63%141% and 46%112% compared to the years ended December 31, 20142016 and 2013,2015, respectively, and our North America product sales backlog as of December 31, 20152017 was $223.8$421.3 million, which represents a declinean increase of approximately 58%77% and 24%88% compared to December 31, 20142016 and 2013,2015, respectively. We believe theserecent booking levels reflect both our customers’ reduced activity levels in response to the decline inexpectation that commodity prices and caution onwill continue to remain above the partlow levels experienced in early 2016 as well as the selective deployment of our customers as they reset capital budgets and seek to reduce costs.

Similarly, in international markets, lower oil and gas prices have had a negative impact on the amount of capital investment by our customers in new projects. However, we believe the impact will be less than we expect to experience incertain North America for two reasons: first, the longer-termbasins.

We expect that industry spending in international markets will begin to recover in 2018. Longer-term fundamentals influencing our international customers’ demand and, second, the long-term contracts we have in place with some of those international customers, including for our contract operations services. Growth in our international markets partially depends in part on international oil and gas infrastructure projects, many of which are based on longer-term plans of our customers that can be driven by their local market demand and local pricing for natural gas. As a result, we believe our international customers make decisions based on longer-term fundamentals that canmay be less tied to near term commodity prices than our North American customers. Therefore,However, lower oil and natural gas prices in international markets have had some negative impacts on the amount of capital investment in new projects by our customers in recent years. Over the long term, we believe the demand for our servicesproducts and productsservices in international markets will continue, and we expect to have opportunities to grow our international businesses over the long term. In the short term, however, our customers have sought to reduce their capital and operating expenditure requirements due to lower oil and natural gas prices. As a result, the demand and pricing for our services and products in international markets have been adversely impacted.businesses. Third party booking activity levels for our manufactured products in international markets during the year ended December 31, 20152017 were $222.3$58.0 million, which represents a decrease of approximately 54%34% and 59%an increase of 24% compared to the yearsyear ended December 31, 20142016 and 2013,2015, respectively, and our international market product sales backlog as of December 31, 20152017 was $264.2$39.7 million, which represents a decrease of approximately 40%42% and 32%9% compared to December 31, 20142016 and 2013,2015, respectively.

Aggregate third party booking activity levels for our manufactured products in North America and international markets during the year ended December 31, 20152017 were $612.8$887.8 million, which represents a decreasean increase of approximately 60%106% and 52%103% compared to the years ended December 31, 20142016 and 2013,2015, respectively. The aggregate product sales backlog for our manufactured products in North America and international markets as of December 31, 20152017 was $488.0$461.0 million, which represents a decreasean increase of approximately 50%51% and 29%72% compared to December 31, 20142016 and 2013,2015, respectively.

In late 2015, we received a customer notice of early termination on a contract operations project Fluctuations in the Eastern Hemisphere that had been operating since the third quartersize and timing of 2009. Based on the January 2016 end date specifiedcustomer requests for bid proposals and awards of new contracts tend to create variability in the notice, we recorded additional depreciation expense of $10.8 million and contract operations revenue of $2.8 million in the fourth quarter of 2015. The additional depreciation expense recognized primarily relatedbooking activity levels from period to capitalized installation costs. Capitalized installation costs, included, among other things, civil engineering, piping, electrical instrumentation and project management costs. The additional revenue recognized related to the recognition of accelerated deferred revenue. Additionally, during the first quarter of 2016, we expect to record additional depreciation expense of approximately $21.5 million and contract operations revenue of approximately $5.6 million related to this terminated contract. Furthermore, as a result of the contract early termination, we expect to incur approximately $6.5 million to demobilize the facility in the first half of 2016 that will be reflected in our statement of operations as cost of sales (excluding depreciation and amortization expense).period.

The timing of any change in activity levels by our customers is difficult to predict. As a result, our ability to project the anticipated activity level for our business, and particularly our product sales segment, is limited. If capital spendingIn the latter part of 2016 and throughout 2017, we experienced an increase in product sales bookings. However, volatility in commodity prices could delay investments by our customers remains low, we expect bookings in our product sales businesssignificant projects, which could result in 2016 to be comparable to or lower than our bookings in 2015. If these reduced booking levels persist for a sustained period, we could experience a material adverse effect on our business, financial condition, results of operations and cash flows.

Our level of capital spending depends on our forecast for the demand for our products and services and the equipment required to provide services to our customers. WeBased on the demand we see for contract operations, we anticipate investing approximately the same level ofmore capital in our contract operations business in 2016 as2018 than we did in 2015.2017. The increased investment during 2018 is driven by several large multi-year projects contracted in 2017, or that are expected to be contracted in 2018, that are scheduled or anticipated to start earning revenue in 2018 and 2019.

Certain Key Challenges and Uncertainties

Market conditions and competition in the oil and natural gas industry and the risks inherent in international markets continue to represent key challenges and uncertainties. In addition to these challenges, we believe the following represent some of the key challenges and uncertainties we will face in the future:

Table of Contents


Global Energy Markets and Oil and Natural Gas Pricing. Our results of operations depend upon the level of activity in the global energy markets, including oil and natural gas development, production, processing and transportation. Oil and natural gas prices and the level of drilling and exploration activity can be volatile and have fallen significantly since the third quarter of 2014. As a result, many producers in the U.S. and other parts of the world, including our customers, reduced their capital and operating spending in 2015 and are expected to do so again in 2016.volatile. If oil and natural gas exploration and development activity and the number of well completions continue to decline due to the reduction in oil and natural gas prices or significant instability in energy markets, we would anticipate a continued decrease in demand and pricing for our natural gas compression and oil and natural gas production and processing equipment and services. For example, unfavorable market conditions or financial difficulties experienced by our customers may result in cancellation of contracts or the delay or abandonment of projects, which could cause our cash flows generated by our product sales and international services to decline and have a material adverse effect on our results of operations and financial condition.

Execution on Larger Contract Operations and Product Sales Projects. Some of our projects have a relatively largerare significant in size and scope, than the majority of our projects, which can translate into more technically challenging conditions or performance specifications for our products and services. Contracts with our customers generally specify delivery dates, performance criteria and penalties for our failure to perform. Any failure to execute such larger projects in a timely and cost effective manner could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Maintaining Expense Levels in Line with Activity Decreases.Personnel, Hiring, Training and Retention. Given the significant erosion in the global energy marketsWe believe our ability to grow may be challenged by our ability to hire, train and industry capital spending activity levels since the third quarter of 2014,retain qualified personnel. Although we have and will continue to reduce our expense levels, including personnel head count and costs, to protect our profitability. Some of these expenses are difficult to reduce, and if we are notbeen able to reduce them commensurate with the level of activity decreases,satisfy our profitabilitypersonnel needs thus far, retaining employees in our industry continues to be a challenge. Our ability to continue our growth will be negatively impacted. Any failure to reduce these costsdepend in a timely manner could have a material adverse effectpart on our business, financial condition, results of operationssuccess in hiring, training and cash flows.retaining these employees.

Summary of Results

As discussed in Note 43 to the Financial Statements, the results from continuing operations for all periods presented exclude the results of our Venezuelan contract operations, businessBelleli CPE and Canadian Operations.Belleli EPC businesses. Those results are reflected in discontinued operations for all periods presented.

Revenue. Revenue during the years ended December 31, 2017, 2016 and 2015 2014 and 2013 was $1,850.6$1,215.3 million, $2,144.6$905.4 million and $2,409.8$1,687.3 million, respectively. The decreaseincrease in revenue during the year ended December 31, 20152017 compared to the year ended December 31, 20142016 was causedprimarily due to a significant increase in revenue in our product sales segment, partially offset by revenue decreases in all three ofrevenue in our contract operations and aftermarket services segments. The decrease in revenue during the year ended December 31, 20142016 compared to the year ended December 31, 20132015 was caused by a revenue decreasedecreases in our product sales segment.and contract operations segments.

Net income.income (loss). We generated net income of $33.9 million during the year ended December 31, 2017, net loss of $227.9 million during the year ended December 31, 2016 and net income of $26.6 million $115.3during the year ended December 31, 2015. The increase in net income during the year ended December 31, 2017 compared to the year ended December 31, 2016 was primarily due to non-cash valuation allowances of $119.8 million recorded against U.S. net deferred tax assets during 2016, an increase in income from discontinued operations, net of tax, an increase in gross margin for our product sales segment, a decrease in depreciation and $123.7 millionamortization expense and a decrease in restructuring and other charges. These activities were partially offset by an increase in SG&A expense. Net income (loss) during the years ended December 31, 2015, 20142017 and 2013,2016 included income from discontinued operations, net of tax, of $39.7 million and loss from discontinued operations, net of tax, of $56.2 million, respectively. Income from discontinued operations, net of tax, for 2017 was positively impacted by recoveries from liquidated damages releases and customer approved change orders related to Belleli EPC. Loss from discontinued operations, net of tax, for 2016 included impairment charges of $68.8 million related to Belleli CPE. The decrease in net income during the year ended December 31, 20152016 compared to the year ended December 31, 20142015 was primarily due to decreasesa decrease in gross margin in our product sales and contract operations gross margin, an increasesegments, non-cash valuation allowances of $119.8 million recorded against U.S. deferred tax assets during 2016 and impairment charges reflected in restructuring and other charges, a $26.5loss from discontinued operations, net of tax, of $68.8 million increase in translation losses related to the functional currency remeasurement of our foreign subsidiaries’ non-functional currency denominated intercompany obligations, an increase in long-lived asset impairment and a $16.0 million decrease in proceeds received from the sale of our Venezuelan subsidiary’s assets to PDVSA Gas S.A. (“PDVSA Gas”).Belleli CPE during 2016. These activities were partially offset by decreasesa decrease in SG&A expense incomeand foreign currency gains of $6.5 million during 2016 compared to foreign currency losses of $35.8 million during 2015. Net loss during the year ended December 31, 2016 included loss from discontinued operations, net of tax, expenseof $56.2 million and depreciation and amortization expense. Netnet income during the yearsyear ended December 31, 2015 and 2014 included income from discontinued operations, net of tax, of $56.1 million and $73.2 million, respectively. The decrease in net income during the year ended December 31, 2014 compared to the year ended December 31, 2013 was primarily due to an increase in depreciation and amortization expense and a $6.5 million loss on short-term investments related to the purchase of Argentine government issued U.S. dollar denominated bonds using Argentine pesos in 2014, partially offset by a decrease in income tax expense, an increase in gross margin and a decrease in long-lived asset impairment. Net income during the years ended December 31, 2014 and 2013 included income from discontinued operations, net of tax, of $73.2 million and $66.1 million, respectively.$4.7 million.

The decrease in revenue during the year ended December 31, 20152017 compared to the year ended December 31, 20142016 was primarily due to a $19.9$15.4 million decrease in revenue in Brazil primarily related to a project which had little incremental costs that commenced and terminated operations in 2014 partially offset by the start-up of new projects during the current year period and a $7.4 million decrease in revenue in the Eastern Hemisphere primarily driven by a decrease in Nigeria. These decreases were partially offset by a $6.8 million increase in revenue in Mexico primarily driven by contractsprojects that commenced orterminated operations in 2016 and a decrease in revenue of $7.7 million resulting from an early termination of a project in Indonesia in January 2016 that had been operating since the third quarter of 2009. These decreases were expandedpartially offset by an $8.0 million increase in scoperevenue in 2014 and 2015.Brazil primarily driven by the start-up of a project during the second half of 2016. Gross margin decreased during the year ended December 31, 20152017 compared to the year ended December 31, 20142016 primarily due to the revenue decrease explained above, partially offset by demobilization expenses of $6.1 million incurred in the prior year period on the early termination of a project in Indonesia discussed above. Gross margin percentage during the year ended December 31, 2017 compared to the year ended December 31, 2016 remained relatively flat.

The decrease in revenue during the year ended December 31, 2017 compared to the year ended December 31, 2016 was primarily due to a decrease in operations and maintenance services of $5.2 million in Colombia, a decrease in parts sales of $7.1 million in China, a $3.3 million decrease in revenue due to the sale of our North America refurbishment and services business in the first quarter of 2017 and a $3.5 million decrease in revenue on a contract in the Middle East resulting from ongoing customer negotiations. These decreases were partially offset by a $4.6 million increase in Brazil primarily driven by increased maintenance services. Gross margin decreased during the year ended December 31, 2017 compared to the year ended December 31, 2016 primarily due to the revenue decrease explained above.

The increase in Latin America driven by our cost reduction plan during the current year period and the devaluation of the Brazilian Real in 2015 which had a positive impact on gross margin percentage, partially offset by the revenue decrease explained above. While our gross margin during the year ended December 31, 2014 benefited2017 compared to the year ended December 31, 2016 was primarily due to increases of $316.3 million and $32.4 million in North America and in the Middle East and Africa region, respectively, partially offset by a decrease of $16.7 million in the Asia Pacific region. The increase in revenue in North America was primarily due to a significant increase in North America booking activities during 2017 compared to 2016. In North America, compression equipment revenue and processing and treating equipment revenue increased by $168.6 million and $160.6 million, respectively, partially offset by a decrease of $10.3 million in production equipment revenue. The increase revenue in the Middle East and Africa region was primarily due to an increase of $29.6 million in processing and treating equipment revenue. The decrease in revenue in the Asia Pacific region was primarily due to a decrease of $15.1 million in compression equipment revenue. Gross margin and gross margin percentage increased during the year ended December 31, 2017 compared to the year ended December 31, 2016 primarily due to the revenue increase explained above and a shift in product mix during the current year period.

Selling, general and administrative
SG&A expense increased during the year ended December 31, 2017 compared to the year ended December 31, 2016 primarily due to the reinstitution of certain incentive compensation that was suspended in 2016 and an increase in third-party professional expenses primarily related to the redesign of our internal controls framework in an effort to remediate previously identified internal control deficiencies, partially offset by cost savings resulting from the portions of our cost reduction plan previously implemented. During the years ended December 31, 2017 and 2016, SG&A expense as a percentage of revenue was 15% and 17%, respectively. The facility previously utilized to manufacture products for our Belleli EPC business has been repurposed to manufacture product sales equipment. As such, certain personnel, buildings, equipment and other assets that were previously related to the Belleli EPC business will remain as part of our continuing operations. As a result, SG&A expense during the years ended December 31, 2017 and 2016 included $2.4 million and $2.3 million, respectively, of costs associated with our ongoing operations at our repurposed facility.

Depreciation and amortization
Depreciation and amortization expense during the year ended December 31, 2017 compared to the year ended December 31, 2016 decreased primarily due to depreciation expense of $22.2 million recognized during the year ended December 31, 2016 on a contract operations project in Indonesia that early terminated operations in January 2016. The depreciation expense recognized on this project in the prior year period primarily related to capitalized installation costs, which included, among other things, civil engineering, piping, electrical instrumentation and project management costs. The project had been operating since the third quarter of 2009.

Long-lived asset impairment
We regularly review the future deployment of our idle compression assets used in our contract operations segment for units that are not of the type, configuration, condition, make or model that are cost efficient to maintain and operate. During the years ended December 31, 2017 and 2016, we determined that one idle compressor unit and 62 idle compressor units, respectively, would be retired from the active fleet. The retirement of these units from the active fleet triggered a review of these assets for impairment, and as a result, we recorded asset impairments of $0.6 million and $12.7 million, respectively, to reduce the book value of each unit to its estimated fair value.

In the fourth quarter of 2017, we classified certain assets within our product sales business that we expect to sell within the next twelve months as assets held for sale. We also determined that certain other assets within our product sales business were assessed to have no future benefit to our ongoing operations. In conjunction with the planned disposition and assessment of certain other assets, we recorded an impairment of long-lived assets that totaled $5.1 million to write-down these assets to their approximate fair values.

During the year ended December 31, 2016, we evaluated other assets for impairment and recorded long-lived asset impairments of $1.7 million on these assets.

Restatement related charges
As discussed in Note 14 to the Financial Statements, during the first quarter of 2016, our senior management identified errors relating to the application of percentage-of-completion accounting principles to specific Belleli EPC product sales projects. During the years ended December 31, 2017 and 2016, we incurred $6.2 million and $30.1 million, respectively, of external costs associated with an ongoing SEC investigation and remediation activities related to the restatement of our financial statements, of which $2.8 million and $11.2 million, respectively, was recovered from Archrock pursuant to the separation and distribution agreement.

Restructuring and other charges
In the second quarter of 2015, we announced a cost reduction plan primarily focused on workforce reductions and the reorganization of certain facilities. These actions were in response to unfavorable market conditions in North America combined with the impact of lower international activity due to customer budget cuts driven by lower oil prices. As a result of this plan, during the year ended December 31, 2017, we incurred restructuring and other charges of $2.6 million primarily related to employee termination benefits. During the year ended December 31, 2016, we incurred $18.1 million of restructuring and other charges as a result of this plan, which primarily related to $14.5 million of employee termination benefits and a $2.9 million charge for the exit of a corporate building under an operating lease. Additionally, during the year ended December 31, 2017, we incurred $0.6 million of costs associated with the Spin-off primarily related to retention awards to certain employees. During the year ended December 31, 2016, we incurred $3.9 million of costs associated with the Spin-off, of which $3.1 million related to retention awards to certain employees. The charges incurred in conjunction with the cost reduction plan and Spin-off are included in restructuring and other charges in our statements of operations. We have substantially completed restructuring activities related to the Spin-off and cost reduction plan. See Note 15 to the Financial Statements for further discussion of these charges.

Interest expense
The increase in interest expense during the year ended December 31, 2017 compared to the year ended December 31, 2016 was primarily due to an increase in the effective interest rate on our debt and interest expense of $2.4 million recorded for the settling of non-income-based tax debt during the current year period in connection with two Brazilian tax programs we entered into in 2017, partially offset by an increase in capitalized interest resulting from increased construction activities and a lower average balance of long-term debt and letters of credit outstanding. As discussed in Note 11to the Financial Statements, the proceeds received in April 2017 from the issuance of the 2017 Notes were used to repay all of the borrowings outstanding under the term loan facility and revolving credit facility. For further discussion on the Brazilian tax programs, see Note 16to the Financial Statements.

Equity in income of non-consolidated affiliates
In March 2012, our Venezuelan joint ventures sold their assets to PDVSA Gas, S.A. (“PDVSA Gas”). We received installment payments, including an annual charge of $10.4 million during the year ended December 31, 2016. As of December 31, 2017, the remaining principal amount due to us was approximately $4 million. Payments we receive from the sale are recognized as equity in income of non-consolidated affiliates in our statements of operations in the periods such payments are received.

Other (income) expense, net
The change in other (income) expense, net, was primarily due to foreign currency losses of $0.7 million during the year ended December 31, 2017 compared to foreign currency gains, net of foreign currency derivatives, of $5.8 million during the year ended December 31, 2016. Foreign currency gains and losses included translation gains of $0.5 million during the year ended December 31, 2017 compared to translation gains, net of foreign currency derivatives, of $8.6 million during the year ended December 31, 2016 related to the currency remeasurement of our foreign subsidiaries’ non-functional currency denominated intercompany obligations. The change in other (income) expense, net, was also due to penalties of $1.8 million incurred for the settling of non-income-based tax debt during the year ended December 31, 2017 in connection with the two Brazilian tax programs discussed above and a decrease of $0.5 million in gain on sale of property, plant and equipment.

Effective tax rate134.8% (261.4)% 396.2 %

For the year ended December 31, 2017, our provision for income tax and effective tax rate of 134.8% was positively impacted by the reversal of previously recorded valuation allowances of $5.6 million against our U.S. AMT carryforwards due to the Tax Reform Act which provided for the cancellation of the AMT and allows for a future refund and/or credit against regular income tax carryforwards. In addition, as a result of the reduction in the U.S. corporate tax rate from 35% to 21%, we recorded a provisional estimate of $15.5 million due to the re-measurement of deferred tax assets and liabilities and recorded a provisional estimate of $10.1 million due to the transition tax on undistributed earnings. Both of these were offset by a tax benefit from the reduction of the valuation allowance previously recorded against our U.S. deferred tax assets. Our effective tax rate was negatively impacted by a $17.1 million additional valuation allowance we recorded on our net U.S. deferred tax assets because beginning in 2016, we were no longer able to support that it was more likely-than-not that we would have sufficient taxable income in the future to realize our U.S. deferred tax assets.

In addition, we recorded a $3.1 million benefit for the change in tax rates due to tax legislation enacted and signed into law in 2017 in Argentina. For further discussion on these new tax laws, see Note 16 to the Financial Statements. Our income tax expense for the year ended December 31, 2017 included benefits related to the reversal of valuation allowances previously recorded against deferred tax assets of $15.2 million related to income tax loss carryforwards that were utilized under two Brazilian tax programs.

For the year ended December 31, 2016, our provision for income tax and effective tax rate of (261.4)% was adversely impacted by valuation allowances recorded against U.S. deferred tax assets and activity at our non-U.S. subsidiaries, which included valuation allowances against certain deferred tax assets, foreign currency devaluations and the settlement of a foreign audit. These negative impacts were partially offset by nontaxable Venezuelan joint venture proceeds and a net nontaxable capital contribution related to the Spin-off.

Our effective tax rate is affected by recurring items, such as tax rates in foreign jurisdictions and the relative amounts of income we earn, or losses we incur, in those jurisdictions. It is also affected by discrete items that may occur in any given year but are not consistent from year to year. The following items had the most significant impact on the difference between our statutory U.S. federal income tax rate of 35.0% and our effective tax rate.

For the year ended December 31, 2017:
A $48.1 million reduction (285.4% reduction) resulting from the release of valuation allowances primarily recorded against certain deferred tax assets of our foreign subsidiaries and federal net operating losses and credits in the U.S.
A $44.9 million increase (266.5% increase) resulting primarily from foreign withholding taxes, negative impacts of foreign currency devaluations in Argentina, and deemed distributions to the U.S. from certain of our non-U.S. subsidiaries. The increase includes a reduction resulting from rate differences between U.S. and foreign jurisdictions.
A $15.5 million increase (92.2% increase) resulting from changes to the tax rates at which certain deferred taxes are recorded due to U.S. tax reform legislation enacted and signed into law in 2017.
An $11.2 million reduction (66.7% reduction) resulting from claiming foreign taxes as credits primarily for foreign withholding taxes. The foreign tax credits are available to offset future payments of U.S. federal income taxes.

A $124.9 million increase (262.7% reduction) resulting from valuation allowances primarily recorded against U.S. deferred tax assets and certain deferred tax assets of our subsidiary in Nigeria.
A $29.4 million increase (61.9% reduction) resulting primarily from foreign withholding taxes, negative impacts of foreign currency devaluations in Argentina and Mexico, settlement of a Nigeria tax audit and deemed distributions to the U.S. from certain of our non-U.S. subsidiaries. The increase includes a reduction resulting from rate differences between U.S. and foreign jurisdictions primarily related to income we earned in Oman and Mexico where the rates are 12.0% and 30.0%, respectively.
A $9.5 million reduction (20.0% increase) resulting from claiming foreign taxes as credits primarily for foreign withholding taxes. The foreign tax credits are available to offset future payments of U.S. federal income taxes.

Income (loss) from discontinued operations, net of tax, includes our Venezuelan subsidiary’s operations that were expropriated in June 2009, including compensation for expropriation, and our Belleli CPE and Belleli EPC businesses.
Income from discontinued operations, net of tax, during the year ended December 31, 2017 compared to the year ended December 31, 2016 increased primarily due to asset impairment charges totaling $68.8 million recorded during the year ended December 31, 2016 for the planned disposition of Belleli CPE and a $42.8 million increase in income from Belleli EPC in 2017 compared to 2016 primarily due to recoveries in 2017 resulting from our release of liquidated damages by a customer in exchange for us releasing them from certain extension of time claims and the obtainment of customer approved change orders. These increases were partially offset by a $19.5 million decrease in income from our Venezuelan subsidiary. During the years ended December 31, 2017 and 2016, we received installment payments, including an annual charge, of $19.7 million and $38.8 million, respectively. As of December 31, 2017, the remaining principal amount due to us was approximately $17 million. We have not recognized amounts payable to us by PDVSA Gas as a receivable and will therefore recognize payments received in the future as income from discontinued operations in the periods such payments are received.

For further details on our discontinued operations, see Note 3 to the Financial Statements.

The decrease in revenue during the year ended December 31, 2016 compared to the year ended December 31, 2015 was primarily due to a decrease in revenue of $34.3 million resulting from an early termination of a project in Indonesia in January 2016 that had been operating since the third quarter of 2009, a $33.0 million decrease in revenue in Mexico primarily driven by projects that terminated operations in 2015 and a reduction of recognized deferred revenue resulting from contract extensions and a $17.7 million decrease in revenue in Argentina primarily due to a devaluation of the Argentine peso since 2015. These decreases were partially offset by an $18.3 million increase in revenue in Brazil primarily driven by the start-up of a Brazilian project our contract operations business is capital intensive, andduring the second half of 2015. Gross margin decreased during the year ended December 31, 2016 compared to the year ended December 31, 2015 primarily due to the revenue decrease described above, excluding the devaluation of the Argentine peso as such, we did havethe impact on gross margin was insignificant. Gross margin percentage during the year ended December 31, 2016 compared to the year ended December 31, 2015 remained flat. The early termination of a project in Indonesia resulted in additional costs during the years ended December 31, 2016 and 2015 in the form of depreciation expense, which is excluded from gross margin. Additionally, excluded from cost of sales and recorded to restructuring and other charges in our statements of operations during the year ended December 31, 2015 were non-cash inventory write-downs of $4.2 million associated with the Spin-off primarily related to the decentralization of shared inventory components between Archrock’s North America contract operations business and our international contract operations business. Gross margin, a non-GAAP financial measure, is reconciled, in total, to net income (loss), its most directly comparable financial measure calculated and presented in accordance with GAAP in Part II, Item 6 (“Selected Financial Data — Non-GAAP Financial Measures”) of this report.

The decrease in revenue during the year ended December 31, 20152016 compared to the year ended December 31, 20142015 was primarily due to decreases in revenue in the Eastern Hemisphere and Latin America of $24.6 million and $10.8 million, respectively. The decrease in revenue in the Eastern Hemisphere was primarily caused by a decrease in revenue of $9.3$7.1 million as a result of the sale of our Australian business in December 2014, an $8.0 million decrease in revenue in Gabon driven by our cessation of activities in the Gabon market in the current year period and a decrease of $4.4 million in part sales in China. The decrease in revenue in Latin America was primarily caused by a decrease of $8.3 million in Bolivia primarily driven by the termination of parts, services and maintenance contracts during the current year period.first quarter of 2015. Gross margin decreased during the year ended December 31, 20152016 compared to the year ended December 31, 20142015 primarily due to decreases in gross margin in Latin America and the Eastern Hemisphere of $3.0 million and $2.7 million, respectively. revenue decrease discussed above. Gross margin percentage during the year ended December 31, 2016 compared to the year ended December 31, 2015 decreased compared to the year ended December 31, 2014 increased primarily due to the receipt of a settlement from a customer in the Eastern HemisphereGabon during the year ended December 31, 2015, which positively impacted revenue and gross margin by $3.7 million and $2.2 million, respectivelyand a decrease.

The decreaseOverall, declines in our product sales bookings and backlog during driven by the market downturn resulted in revenue decreases during 2016 in each of the regions where we operate. During the year ended December 31, 20152016 compared to the year ended December 31, 2014 was due to a decrease in2015, revenue decreased by $528.2 million, $101.4 million and $67.6 million in North America, and the Eastern Hemisphere of $194.0 million and $77.4 million, respectively, partially offset by higher revenue in Latin America, of $36.3 million.respectively. The decrease in revenue in North America was due to decreases of $109.2$270.8 million, $212.1 million and $92.6$45.3 million in compression equipment revenue and production and processing equipment revenue, respectively, partially offset by an increase of $7.8 million incompression equipment revenue and installation revenue.revenue, respectively. The decrease in the Eastern Hemisphere revenue was due to decreases of $33.7$40.4 million, $28.6$31.3 million and $15.1$29.7 million in installation revenue, compression equipment revenue and production and processing equipment revenue, respectively. The decrease in Latin America revenue was due to decreases of $35.6 million, $24.2 million and $7.8 million in compression equipment revenue, installation revenue and production and processing equipment revenue, respectively. The increase in Latin America revenue was primarily due to increases of $25.9 million and $10.1 million in compression equipment revenue and installation revenue, respectively. The decreases in gross margin and gross margin percentage were primarily caused by the revenue decrease explained above, continued weakening market conditions over the past year resulting in lower bookings at morea competitive prices in North Americapricing environment and an increase in under-absorption caused by reduced activities and management’s decision to maintain a certain level of $3.2 million in expense for inventory reserves in North America. These decreases were partially offset by costs charged to one project in North America related to a warranty expense accrual of approximately $7.0 million during the year ended December 31, 2014. Additionally, project execution delays on significant Belleli EPC projects in the Eastern Hemisphere during the years ended December 31, 2015 and 2014 resulted in estimated loss contract provisions of $30.1 million and $36.6 million, respectively, which negatively impacted gross margin percentage for each period. Revenue and cost of sales for Belleli EPC projects were $103.2 million and $134.8 million, respectively, during the year ended December 31, 2015 compared to $115.5 million and $148.9 million, respectively, during the year ended December 31, 2014.manufacturing capacity. Excluded from cost of sales and recorded to restructuring and other charges in our statements of operations during the year ended December 31, 2015 were non-cash inventory write-downs of $4.5 million primarily related to our decision to exit the manufacturing of cold weather packages, which had historically been performed at a product sales facility in North America we decided to close.

The decrease in SG&A expense during the year ended December 31, 2016 compared to the year ended December 31, 2015 was driven by our cost reduction plan and included a $14.7 million decrease in international compensation and benefits costs and a $13.1 million decrease in corporate expenses. SG&A expense as a percentage of revenue was 17% and 12% during the years ended December 31, 2016 and 2015, respectively. The increase in SG&A expense as a percentage of revenue was primarily due to a significant decrease in product sales revenue during the year ended December 31, 2016 compared to the year ended December 31, 2015. For the periods prior to the Spin-off, SGSG&A expense includes expense allocations for certain functions, including allocations of expenses related to executive oversight, accounting, treasury, tax, legal, human resources, procurement and information technology services performed by Archrock on a centralized basis that historically have not been recorded at the segment level. These costs were allocated to us systematically based on specific department function and revenue. Included in SG&A expense during the yearsyear ended December 31, 2015 and 2014 werewas $46.9 million of allocated corporate expenses incurred by Archrock prior to the Spin-off.Archrock. The actual costs we would have incurred if we had been a stand-alone public company would depend on multiple factors, including organizational structure and strategic decisions made in various areas, including information technology and infrastructure. The decrease in SG&A expense during the year ended December 31, 2015 compared to the year ended December 31, 2014 was attributable to a $12.2 million decrease in compensation

SG&A expense as a percentage of revenue was 12% during each of the years ended December 31, 2015 and 2014.

amortization
Depreciation and amortization expense during the year ended December 31, 20152016 compared to the year ended December 31, 20142015 decreased primarily due to $26.4a decrease of $16.5 million in depreciation of installation costs recognized during the year ended December 31, 2014expense on acertain contract operations projectprojects in Brazil that commenced and terminated operations in 2014. Prior to the start-up of this project, we capitalized $1.9 million and $24.5 million of installation costs during the years ended December 31, 2014 and 2013, respectively. In late 2015, we received a customer notice of early termination on a contact operations project in the Eastern Hemisphere specifying an end date of January 2016. The project had been operating since the third quarter of 2009. As a result, we recorded additional depreciation expense of $10.8 million in the fourth quarter of 2015Latin America primarily related to capitalized installation costs.costs that were fully depreciated during 2016 and 2015. Capitalized installation costs, included, among other things, civil engineering, piping, electrical instrumentation and project management costs.

During the year ended December 31, 2015, we reviewedLong-lived asset impairment
We regularly review the future deployment of our idle compression assets used in our contract operations segment for units that wereare not of the type, configuration, condition, make or model that are cost efficient to maintain and operate. Based on this review,During the years ended December 31, 2016 and 2015, we determined that 62 idle compressor units and 93 idle compressor units, totaling approximately 72,000 horsepowerrespectively, would be retired from the active fleet. The retirement of these units from the active fleet triggered a review of these assets for impairment. As a result, we recorded aasset impairments of $12.7 million and $19.4 million asset impairmentduring the years ended December 31, 2016 and 2015, respectively, to reduce the book value of each unit to its estimated fair value. The fair value

During the year ended December 31, 2016, we evaluated other assets for impairment and recorded long-lived asset impairments of each unit was estimated based$1.7 million on either the expected net sale proceeds compared to other fleet units we recently sold and/or a review of other units recently offered for sale by third parties, or the estimated component value of the equipment on each compressor unit that we plan to use.these assets.

During the first quarter of 2015, we evaluated a long-term note receivable from the purchaser of our Canadian Operations for impairment. This review was triggered by an offer from the purchaser of our Canadian Operations to prepay the note receivable at a discount to its then current book value. The fair value of the note receivable as of March 31, 2015 was based on the amount offered by the purchaser of our Canadian Operations to prepay the note receivable. The difference between the book value of the note receivable at March 31, 2015 and its fair value resulted in the recording of an impairment of long-lived assets of $1.4 million during the year ended December 31, 2015.million. In April 2015, we accepted the offer to early settle this note receivable.

2016, our senior management identified errors relating to the application of percentage-of-completion accounting principles to specific Belleli EPC product sales projects. As a result, the Audit Committee of the Company’s Board of Directors initiated an internal investigation, including the use of services of a forensic accounting firm. Management also engaged a consulting firm to assist in accounting analysis and compilation of restatement adjustments. During the year ended December 31, 2014,2016, we evaluatedincurred $30.1 million of costs associated with the future deploymentrestatement of our idle fleetfinancial statements and determinedrelated SEC investigation, of which $11.2 million of cash was recovered from Archrock in the fourth quarter of 2016 pursuant to retire approximately 20 idle compressor units, representing approximately 18,000 horsepower, previously used to provide services in our contract operations segment. As a result, we performed an impairment reviewthe separation and recorded a $2.8 million asset impairment to reduce the book value of each unit to its estimated fair value. The fair value of each unit was estimated based on the estimated component value of the equipment we plan to use.distribution agreement.

In connection with our fleet review during 2014, we evaluated for impairment idle units that had been culled from our fleet in prior yearsRestructuring and were available for sale. Based upon that review, we reduced the expected proceeds from disposition for certain of the remaining units. This resulted in an additional impairment of $1.1 million to reduce the book value of each unit to its estimated fair value.other charges

In the second quarter of 2015, we announced a cost reduction plan, primarily focused on workforce reductions and the reorganization of certain product sales facilities. These actions were in response to unfavorable market conditions in North America combined with the impact of lower international activity due to customer budget cuts driven by lower oil prices. AsDuring the year ended December 31, 2016, we incurred $18.1 million of restructuring and other charges as a result of this plan, duringwhich were primarily related to $14.5 million of employee termination benefits and a $2.9 million charge for the exit of a corporate building under an operating lease. During the year ended December 31, 2015, we incurred $16.4$15.6 million of restructuring and other charges as a result of this plan, which $12.4 millionwere primarily related to $9.6 million of employee termination benefits and consulting fees and $4.0 million related toof non-cash write-downs of inventory. The non-cash inventory write-downs were the result of our decision to exit the manufacturing of cold weather packages, which had historically been performed at a product sales facility in North America we decided to close.close in 2015. Additionally, duringwe incurred restructuring and other charges associated with the Spin-off. During the year ended December 31, 2016, we incurred $3.9 million of costs associated with the Spin-off, which were primarily related to expenses of $3.1 million for retention awards to certain employees. During the year ended December 31, 2015, we incurred $15.7 million of costs associated with the Spin-off, which were primarily related to non-cash inventory write-downs of $4.7 million, financial advisor fees of $4.6 million paid at the completion of the Spin-off, non-cash inventory write-downs of $4.7 million, expenses of $3.1 million for retention awards to certain employees and a one-time cash signing bonus of $2.0 million paid to our new Chief Executive Officer of $2.0 million and costs to start-up certain stand-alone functions of $1.3 million.Officer. Non-cash inventory write-downs were primarily related to the decentralization of shared inventory components between Archrock’s North America contract operations business and our international contract operations business. The charges incurred in conjunction with the cost reduction plan and Spin-off are included in restructuring and other charges in our statements of operations. See Note 1415 to the Financial Statements for further discussion of these charges.

Interest expense
The increase in interest expense during the year ended December 31, 20152016 compared to the year ended December 31, 20142015 was primarily due to borrowings under our revolving credit facility and term loan facility (collectively, the “Credit Facility”) that became available on November 3, 2015. During the period between November 3, 2015 andyear ended December 31, 2015,2016, the average daily outstanding borrowings under the Credit Facility were $557.0$422.9 million. Prior to the Spin-off, third party debt of Archrock, other than debt attributable to capital leases, was not allocated to us as we were not the legal obligor of the debt and Archrock’s borrowings were not directly attributable to our business.

Equity in income of non-consolidated affiliates
In March 2012, our Venezuelan joint ventures sold their assets to PDVSA Gas. We received installment payments, including an annual charge, of $15.2$10.4 million and $14.7$15.2 million during the years ended December 31, 2016 and 2015, and 2014, respectively. The remaining principal amount due to us of approximately $13 million as of December 31, 2015, is payable in cash installments through the first quarter of 2016. In January 2016, we received an installment payment, including an annual charge, of $5.2 million. Payments we receive from the sale will be recognized as equity in (income) lossincome of non-consolidated affiliates in our statements of operations in the periods such payments are received.

Other (income) expense, net
The change in other (income) expense, net, during the year ended December 31, 2016 compared to the year ended December 31, 2015 was primarily due to foreign currency gains, net of losses on foreign currency derivatives, of $35.4 million and $7.8$5.8 million during the yearsyear ended December 31, 2015 and 2014, respectively.2016 compared to foreign currency losses of $35.8 million during the year ended December 31, 2015. Our foreign currency gains and losses included translation gains, net of losses on foreign currency derivatives, of $8.6 million during the year ended December 31, 2016 compared to translation losses of $30.1 million and $3.6 million during the yearsyear ended December 31, 2015 and 2014, respectively, related to the currency remeasurement of our foreign subsidiaries’ non-functional currency denominated intercompany obligations. Of the foreign currency losses recognized during the year ended December 31, 2015, $29.7 million was attributable to our Brazil subsidiary’s U.S. dollar denominated intercompany obligations and were the result of a currency devaluation in Brazil and increases in our Brazil subsidiary’s intercompany payables 2015.

The increase in revenue during the year ended December 31, 2014 compared to the year ended December 31, 2013 was primarily due to a $16.1 million increase in revenue in Brazil primarily related to the start-up of a project in 2014 with little incremental costs, an $8.0 million increase in revenue related to contracts that commenced in 2013 in Trinidad and Iraq, a $3.8 million increase in revenue in Mexico primarily due to accelerated revenues associated with a project that terminated in the second quarter of 2014 and a $3.8 million increase in revenue in Indonesia primarily due to an increase in production. These increases in revenue were partially offset by a $7.2 million decrease in revenue in Argentina driven by devaluation of the Argentine peso in 2014 partially offset by higher rates in 2014 and a $6.1 million decrease in Colombia primarily due to recognition of revenue with no incremental cost on the termination of a contract during the year ended December 31, 2013. Gross margin (defined as revenue less cost of sales, excluding depreciation and amortization expense) and gross margin percentage increased during the year ended December 31, 2014 compared to the year ended December 31, 2013 primarily due to the revenue increase explained above, excluding the devaluation of the Argentine peso in 2014 as the impact on gross margin and gross margin percentage was insignificant. While our gross margin during the year ended December 31, 2014 benefited from the start-up of a Brazilian project, our contract operations business is capital intensive, and as such, we did have additional incremental costs in the form of depreciation expenses which is excluded from gross margin. Gross margin, a non-GAAP financial measure, is reconciled, in total, to net income (loss), its most directly comparable financial measure calculated and presented in accordance with GAAP in Part II, Item 6 (“Selected Financial Data — Non-GAAP Financial Measures”) of this report.

The decrease in revenue during the year ended December 31, 2014 compared to the year ended December 31, 2013 was due to lower revenue in North America, the Eastern Hemisphere and Latin America of $114.7 million, $87.1 million and $83.3 million, respectively. The decrease in revenue in North America was due to a decrease of $143.6 million in installation revenue primarily due to a project for one customer that was completed in 2013 and a decrease of $122.4 million in production and processing equipment revenue, partially offset by a $151.3 million increase in compression equipment revenue. The decrease in revenue in the Eastern Hemisphere was primarily due to a decrease of $106.4 million in compression equipment revenue, partially offset by an increase of $24.0 million in installation revenue. The decrease in Latin America revenue was due to decreases of $59.2 million, $14.0 million and $10.1 million in installation revenue, production and processing equipment revenue and compression equipment revenue, respectively. The decrease in gross margin was primarily caused by the revenue decrease explained above, incremental losses of $14.2 million on Belleli EPC projects in the Eastern Hemisphere and additional costs charged to one project in North America related to a warranty expense accrual of approximately $7.0 million during the year ended December 31, 2014, partially offset by cost overruns on three large turnkey projects recorded during the year ended December 31, 2013 of approximately $53.0 million. Revenue and cost of sales for Belleli EPC projects were $115.5 million and $148.9 million, respectively, during the year ended December 31, 2014 compared to $75.8 million and $96.0 million, respectively, during the year ended December 31, 2013. The incremental losses on Belleli EPC projects were primarily related to estimated loss contract provisions of $36.6 million recorded on significant projects during the year ended December 31, 2014 primarily driven by project execution delays, partially offset by estimated loss contract provisions of $22.8 million recorded on significant projects during the year ended December 31, 2013 primarily driven by project execution delays. The increase in gross margin percentage was primarily caused by cost overruns on three large turnkey projects recorded during the year ended December 31, 2013, partially offset by incremental losses on Belleli EPC projects and additional costs charged to a project in North America related to a warranty expense accrual during the year ended December 31, 2014.

SG&A expense includes expense allocations for certain functions, including allocations of expenses related to executive oversight, accounting, treasury, tax, legal, human resources, procurement and information technology services performed by Archrock on a centralized basis that historically have not been recorded at the segment level. These costs were allocated to us systematically based on specific department function and revenue. Included in SG&A expense during the years ended December 31, 2014 and 2013 were $68.3 million and $62.6 million, respectively, of corporate expenses incurred by Archrock. The actual costs we would have incurred if we had been a stand-alone public company would depend on multiple factors, including organizational structure and strategic decisions made in various areas, including information technology and infrastructure. SG&A as a percentage of revenue was 12% and 11% during the years ended December 31, 2014 and 2013, respectively.

Depreciation and amortization expense during the year ended December 31, 2014 compared to the year ended December 31, 2013 increased primarily due to $26.4 million of depreciation of installation costs recognized during 2014 on a contract operations project in Brazil that commenced and terminated operations in 2014. Prior to the start-up of this project, we capitalized $1.9 million and $24.5 million of installation costs during the years ended December 31, 2014 and 2013, respectively. Capitalized installation costs included, among other things, civil engineering, piping, electrical instrumentation and project management costs. Installation costs capitalized on contract operations projects are depreciated over the life of the underlying contract. In addition, depreciation expense increased due to property, plant and equipment additions.

During the year ended December 31, 2014, we evaluated the future deployment of our idle fleet and determined to retire approximately 20 idle compressor units, representing approximately 18,000 horsepower, previously used to provide services in our contract operations segment. As a result, we performed an impairment review and recorded a $2.8 million asset impairment to reduce the book value of each unit to its estimated fair value. The fair value of each unit was estimated based on the estimated component value of the equipment we plan to use.

In connection with our fleet review during 2014, we evaluated for impairment idle units that had been culled from our fleet in prior years and were available for sale. Based upon that review, we reduced the expected proceeds from disposition for certain of the remaining units. This resulted in an additional impairment of $1.1 million to reduce the book value of each unit to its estimated fair value.

In July 2013, as part of our continued emphasis on simplification and focus on our core business, we sold the entity that owned our product sales facility in the United Kingdom. As a result, we recorded impairment charges of $11.9 million during the year ended December 31, 2013.

The decrease in interest expense during the year ended December 31, 2014 compared to the year ended December 31, 2013 was primarily due to a decrease in letters of credit issued for performance guarantees.

In March 2012, our Venezuelan joint ventures sold their assets to PDVSA Gas. We received installment payments, including an annual charge, of $14.7 million and $19.0 million during the years ended December 31, 2014 and 2013, respectively. The remaining principal amount due to us is payable in quarterly cash installments through the first quarter of 2016. Payments we receive from the sale will be recognized as equity in (income) loss of non-consolidated affiliates in our statements of operations in the periods such payments are received.

The change in other (income) expense, net, was primarily due to a $6.5 million loss recognized during the year ended December 31, 2014 on short-term investments related to the purchase of $24.3 million of Argentine government issued U.S. dollar denominated bonds using Argentine pesos and an increase of $4.7 million in foreign currency losses in 2014. Foreign currency losses included translation losses of $3.6 million and $4.3 million during the years ended December 31, 2014 and 2013, respectively, related to the functional currency remeasurement of our foreign subsidiaries’ non-functional currency denominated intercompany obligations.

Our effective tax rate is affected by recurring items, such as tax rates in foreign jurisdictions and the relative amounts of income we earn, or losses we incur, in those jurisdictions. It is also affected by discrete items that may occur in any given year but are not consistent from year to year. In addition to net state income taxes, the following items had the most significant impact on the difference between our statutory U.S. federal income tax rate of 35.0% and our effective tax rate.

For the year ended December 31, 2014:

A $33.8 million (27.9%) increase resulting primarily from foreign withholding taxes, decreases in available net operating losses mostly related to our subsidiaries in the Netherlands, and negative impacts of foreign currency devaluations in Argentina and Mexico. The increase includes a reduction resulting from rate differences between U.S. and non-U.S. jurisdictions primarily related to income we earned in Oman, Mexico and Thailand where the rates are 12.0%, 30.0% and 20.0%, respectively.

A $19.2 million (15.8%) increase resulting from valuation allowances primarily recorded against deferred tax assets for net operating losses of our subsidiaries in Brazil, Italy and the Netherlands and accrued loss contracts for Belleli EPC projects. The increase includes a reduction in valuation allowances related to decreases in available net operating losses mostly related to our subsidiaries in the Netherlands.

A $10.9 million (9.0%) reduction resulting from claiming foreign taxes as credits primarily for foreign withholding taxes. The foreign tax credits are available to offset future payments of U.S. federal income taxes.

A $5.2 million (4.3%) reduction due to $14.7 million of nontaxable proceeds from sale of joint venture assets in Venezuela.

For the year ended December 31, 2013:

A $33.5 million (21.1%) increase resulting from valuation allowances primarily recorded against deferred tax assets for net operating losses of our subsidiaries in Brazil, Italy and the Netherlands and accrued loss contracts for Belleli EPC projects.

A $30.5 million (19.2%) increase resulting primarily from foreign withholding taxes and negative impacts of foreign currency devaluations in Argentina.

A $16.4 million (10.3%) reduction resulting from claiming foreign taxes as credits primarily for foreign withholding taxes. The foreign tax credits are available to offset future payments of U.S. federal income taxes.

Income from discontinued operations, net of tax, during the years ended December 31, 2014 and 2013 includes our operations in Venezuela that were expropriated in June 2009, including compensation for expropriation and costs associated with our arbitration proceeding, and results from our Canadian Operations.

As discussed in Note 4 to the Financial Statements, in August 2012, our Venezuelan subsidiary sold its previously nationalized assets to PDVSA Gas. We received installment payments, including an annual charge, totaling $72.6 million and $69.3 million during the years ended December 31, 2014 and 2013, respectively. The remaining principal amount due to us is payable in quarterly cash installments through the third quarter of 2016. We have not recognized amounts payable to us by PDVSA Gas as a receivable and will therefore recognize quarterly payments received in the future as income from discontinued operations in the periods such payments are received. The proceeds from the sale of the assets are not subject to Venezuelan national taxes due to an exemption allowed under the Venezuelan Reserve Law applicable to expropriation settlements. In addition, and in connection with the sale, we and the Venezuelan government agreed to waive rights to assert certain claims against each other.

In June 2012, we committed to a plan to sell our Canadian Operations. In connection with the planned disposition, we recorded impairment charges totaling $6.4 million during the year ended December 31, 2013. As discussed in Note 4 to the Financial Statements, in July 2013, we completed the sale of our Canadian Operations.

The increasedecrease in working capital was primarily due to decreases in accounts payable, billings on uncompleted contracts in excess of costs and estimated earnings, deferred revenue and accrued liabilities, partially offset by decreases in inventory, costs and estimated earnings in excess of billings on uncompleted contracts and accounts receivable. The decreasesincreases in accounts payable and billings on uncompleted contracts in excess of costs and estimated earnings were primarily caused by lower product sales activity in North America. Theand a decrease in deferred revenue was primarily due to the timing of product sales projects in North America and the Eastern Hemisphere and the timing of contract operations projects in Mexico,inventory, partially offset by an increase in deferred revenue related to a product sales project in Bolivia. The decrease in accrued liabilities was primarily due to decreases in accrued salaries and other benefits and income taxes payable. The decrease in inventory was primarily driven by a decrease in work in progress in North America largely resulting from product sales projects with affiliates accounted for under the completed contract method prior to the Spin-off and lower product sales activity. The decreaseincreases in accounts receivable was primarily driven by the timing of payments from customers in Mexico and Bolivia. The decrease in costs and estimated earnings in excess of billings on uncompleted contracts wasand a decrease in current liabilities associated with discontinued operations. The increases in accounts payable, billings on uncompleted contracts in excess of costs and estimated earnings, accounts receivable and costs and estimated earnings in excess of billings on uncompleted contracts were primarily causeddriven by lowerhigher product sales activity in North America. The decrease in current liabilities associated with discontinued operations was primarily due to substantially exiting our Belleli EPC business in the Eastern Hemisphere.

2017. The decrease in inventory was primarily due to the reclassification of inventory to current assets held for sale related to certain inventory within our products sales business that we expect to sell within the next twelve months, a decrease in product sales inventory resulting from recent activities in North America and the utilization of inventory on capital projects during the current year period.

Operating Activities.  The decrease in net cash provided by operating activities during the year ended December 31, 20152017 compared to the year ended December 31, 20142016 was primarily attributable to a decreaselower current period decreases in gross margin in all of our segments and restructuring and other charges paid in the current year period,working capital, partially offset by lower current period increases in working capital and lower SG&A expense during the current year period.improved gross margins for our product sales segment. Working capital changes during the year ended December 31, 2015 compared to the year ended December 31, 20142017 included a decrease of $80.4 million in inventory during the year ended December 31, 2015 and an increase of $55.1 million in accounts receivable during the year ended December 31, 2014, partially offset by a decrease of $78.2$62.0 million in accounts payable and other liabilities, an increase of $65.3 million in accounts receivable and a decrease of $40.9 million in costs and estimated earnings versus billings on uncompleted contracts.

Investing Activities.  The increase in net cash used in investing activities during the year ended December 31, 20152017 compared to the year ended December 31, 20142016 was primarily attributable to a $5.6$58.0 million increase in capital expenditures and a $10.4 million decrease in proceeds received from the sale of our joint ventures’ previously nationalized assets, partially offset by a $6.1 million increase in proceeds from the sale of property, plant and equipment and a $1.1 million decrease in capital expenditures, partially offset by $5.4 million of net proceeds received from the settlement of our outstanding note receivable for the sale of our Canadian Operations in the current year period.equipment.

Financing Activities.  The decrease in net cash used in financing activities during the year ended December 31, 20152017 compared to the year ended December 31, 20142016 was primarily attributable to a decrease in net borrowingsrepayments of $530.0$204.1 million on our Credit Facility during the year ended December 31, 2015 and a $40.3$4.5 million decrease in net distributionscash transferred to parent,Archrock pursuant to the separation and distribution agreement, partially offset by a transfer$7.1 million increase in cashdebt issuance costs.

Capital Requirements.  Our contract operations business is capital intensive, requiring significant investment to maintain and upgrade existing operations. Our capital spending is primarily dependent on the demand for our contract operations services and the availability of the type of equipment required for us to render those contract operations services to our customers. Our capital requirements have consisted primarily of, and we anticipate will continue to consist of, the following:

growth capital expenditures, which are made to expand or to replace partially or fully depreciated assets or to expand the operating capacity or revenue generating capabilities of existing or new assets, whether through construction, acquisition or modification; and

maintenance capital expenditures, which are made to maintain the existing operating capacity of our assets and related cash flows further extending the useful lives of the assets.

Table of Contents


The majority of our growth capital expenditures are related to theinstallation costs on integrated projects and acquisition costcosts of new compressor units and processing and treating equipment that we add to our fleet and installation costs on integrated projects.contract operations fleet. In addition, growth capital expenditures can include the upgrading of major components on an existing compressor unit where the current configuration of the compressor unit is no longer in demand and the compressor unit is not likely to return to an operating status without the capital expenditures. These latter expenditures substantially modify the operating parameters of the compressor unit such that it can be used in applications for which it previously was not suited. Maintenance capital expenditures are related to major overhauls of significant components of a compressor unit, such as the engine, compressor and cooler, that return the components to a “like new” condition, but do not modify the applications for which the compressor unit was designed.

Growth capital expenditures were $105.2$104.9 million, $97.9$53.0 million and $36.5$105.2 million during the years ended December 31, 2015, 20142017, 2016 and 2013,2015, respectively. The increase in growth capital expenditures during the year ended December 31, 20152017 compared to the year ended December 31, 20142016 was primarily due to an increase in installation expenditures on integrated projects in Bolivia and Brazil.Oman during 2017. The increasedecrease in growth capital expenditures during the year ended December 31, 20142016 compared to the year ended December 31, 20132015 was primarily due to an increase in investment in new compression equipment in Latin America and an increasea decrease in installation expenditures on integrated projects in BrazilBolivia and Mexico.Brazil.

Maintenance capital expenditures were $27.3$15.7 million, $24.4$14.4 million and $21.6$27.3 million during the years ended December 31, 2017, 2016 and 2015, 2014 and 2013, respectively. MaintenanceThe increase in maintenance capital expenditures during the year ended December 31, 2017 compared to the year ended December 31, 2016 was primarily driven by increased overhaul activities. The decrease in maintenance capital expenditures during the year ended December 31, 2016 compared to the year ended December 31, 2015 was primarily due to delayed discretionary spending as a result of the market downturn. Historically, maintenance capital expenditures have remained relatively flat from year to year primarily as a result of routine scheduled overhaul activities. We intend to grow our business both organically and through third-party acquisitions. If we are successful in growing our business in the future, we would expect our maintenance capital expenditures to increase over the long term.

We generally invest funds necessary to manufacture contract operations fleet additions when our idle equipment cannot be reconfigured to economically fulfill a project’s requirements and the new equipment expenditure is expected to generate economic returns over its expected useful life that exceeds our targeted return on capital. We currently plan to spend approximately $130$240 million to $150$300 million in capital expenditures during 2016,2018, including (1) approximately $95$200 million to $110$250 million on contract operations growth capital expenditures and (2) approximately $20 million to $25$40 million on equipment maintenance capital related to our contract operations business.
 
On July 10, 2015, weLong-Term Debt. We and our wholly owned subsidiary, EESLP, entered into a $750.0 millionare parties to an amended and restated credit agreement (the “Credit Agreement”) with Wells Fargo, as the administrative agent, and various financial institutions as lenders. On October 5, 2015, the parties amended and restated the Credit Agreement to provide for a $925.0 million credit facility, consisting of a $680.0 million revolving credit facility and a $245.0 million term loan facility (collectively, the “Credit Facility”). Availability under the Credit Facility was subject to the satisfaction of certain conditions precedent, including the consummation of the Spin-off on or before January 4, 2016 (the date on which those conditions were satisfied, November 3, 2015, is referred to as the “Initial Availability Date”). The revolving credit facility will matureexpiring in November 2020 and thepreviously included a term loan facility will mature in November 2017.facility.

The principal amount of $12.3 million due in November 2016average daily borrowings under the term loan facility is classified as long-term in our balance sheet at December 31, 2015 because we have the intent and ability to refinance the current principal amount due with borrowings under our existing revolving credit facility. On November 3, 2015, EESLP incurred approximately $300.0 million of indebtedness under the revolving credit facility were $87.9 million and $245.0$422.9 million, of indebtedness under the term loan facility. Pursuant to the separation and distribution agreement with Archrock and certain of our and Archrock’s respective affiliates, on November 3, 2015, EESLP transferred $532.6 million of net proceeds from borrowings under the Credit Facility to Archrock to allow it to repay a portion of its indebtedness in connection with the Spin-off.

As of December 31, 2015, we had $285.0 million in outstanding borrowings and $116.4 million in outstanding letters of credit under our revolving credit facility. At December 31, 2015, taking into account guarantees through letters of credit, we had undrawn and available capacity of $278.6 million under our revolving credit facility.

Revolving borrowings under the Credit Facility bear interest at a rate equal to, at our option, either the Base Rate or LIBOR (or EURIBOR, in the case of Euro-denominated borrowings) plus the applicable margin. The applicable margin for revolving borrowings varies (i) in the case of LIBOR loans, from 1.50% to 2.75% and (ii) in the case of Base Rate loans, from 0.50% to 1.75%, and will be determined based on our total leverage ratio pricing grid. “Base Rate” means the highest of the prime rate, the federal funds effective rate plus 0.50% and one-month LIBOR plus 1.00%. Until the term loan facility is refinanced in full with the proceeds of a qualified capital raise (as defined in the Credit Agreement), the applicable margin for borrowings under the revolving credit facility will be increased by 1.00% until the first anniversary of the Initial Availability Date and by 1.50% following the first anniversary of the Initial Availability Date. Term loan borrowings under the Credit Facility will bear interest at a rate equal to, at our option, either (1) the Base Rate plus 4.75%, or (2) the greater of LIBOR or 1.00%, plus 5.75%.respectively. The weighted average annual interest rate on outstanding borrowings under the revolving credit facility at December 31, 20152016 was 3.1%5.0%. The annual interest rate on the outstanding balance of the term loan facility at December 31, 20152016 was 6.8%.

As of December 31, 2017, we had $39.7 million in outstanding letters of credit under our revolving credit facility and, alltaking into account guarantees through letters of credit, we had undrawn capacity of $640.3 million under our Significant Domestic Subsidiariesrevolving credit facility. Our Credit Agreement limits our Total Debt to EBITDA ratio (as defined in the Credit Agreement) guarantee EESLP’s obligations under the Credit Facility. In addition, EESLP’s obligations under the Credit Facility are secured by (1) substantially all of our assets and the assets of EESLP and our Significant Domestic Subsidiaries located in the U.S., including certain real property, and (2) all of the equity interests of our U.S. restricted subsidiaries (other than certain excluded subsidiaries) (as defined in the Credit Agreement) and 65% of the voting equity interests in certain of our first-tier foreign subsidiaries.

We are required to prepay borrowings outstanding under the term loan facility with the net proceeds of certain asset sales, equity issuances, debt incurrences and other events (subject to, in certain circumstances, our right to reinvest the proceeds within a specified period). In addition, if the total leverage ratio as ofon the last day in anyof the fiscal year isquarter to no greater than 2.504.50 to 1.00, we are required to prepay1.0. As a result of this limitation, $585.2 million of the $640.3 million of undrawn capacity under our revolving credit facility was available for additional borrowings outstanding under the term loan facility with a portionas of Excess Cash Flow (as defined in the Credit Agreement) for that fiscal year equal to (a) 50% of Excess Cash Flow if the total leverage ratio is greater than 3.00 to 1.00 or (b) 25% of Excess Cash Flow if the total leverage ratio is greater than 2.50 to 1.00 but less than or equal to 3.00 to 1.00.December 31, 2017.

The Credit Agreement contains various covenants with which we, EESLP and our respective restricted subsidiaries must comply, including, but not limited to, limitations on the incurrence of indebtedness, investments, liens on assets, repurchasing equity, making distributions, transactions with affiliates, mergers, consolidations, dispositions of assets and other provisions customary in similar types of agreements. We are required to maintain, on a consolidated basis, a minimum interest coverage ratio (as defined in the Credit Agreement) of 2.25 to 1.00; a maximum total leverage ratio of 3.75 to 1.00 prior to the completion of a qualified capital raise (as defined in the Credit Agreement) andof 4.50 to 1.00 thereafter;1.00; and following the completion of a qualified capital raise, a maximum senior secured leverage ratio (as defined in the Credit Agreement) of 2.75 to 1.00. As of December 31, 2015,2017, Exterran Corporation maintained a 9.3an 8.3 to 1.0 interest coverage ratio and a 2.11.7 to 1.0 total leverage ratio and a 2.1 to 1.0 senior secured leverage ratio. As of December 31, 2015,2017, we were in compliance with all financial covenants under the Credit Agreement.

In April 2017, our 100% owned subsidiaries EESLP and EES Finance Corp. issued the 2017 Notes, which consists of $375.0 million aggregate principal amount of senior unsecured notes. The 2017 Notes are guaranteed by us on a senior unsecured basis. The net proceeds of $367.1 million from the 2017 Notes issuance were used to repay all of the borrowings outstanding under the term loan facility and revolving credit facility and for general corporate purposes. Additionally, pursuant to the separation and distribution agreement from the Spin-off, EESLP used proceeds from the issuance of the 2017 Notes to pay a subsidiary of Archrock $25.0 million in satisfaction of EESLP’s obligation to pay that sum following the occurrence of a qualified capital raise. The transfer of cash to Archrock’s subsidiary was recognized as a reduction to additional paid-in capital during the year ended December 31, 2017.

We may from time to time seek to retire or purchase our outstanding debt through cash purchases and/or exchanges for equity securities, in open market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

Historically, we have financed capital expenditures primarily with net cash provided by operating activities. Our ability to access the capital markets may be restricted at athe time when we would like, or need, to do so, which could have an adverse impact on our ability to maintain our operations and to grow. If any of our lenders become unable to perform their obligations under ourthe Credit Facility,Agreement, our borrowing capacity under our revolving credit facility could be reduced. Inability to borrow additional amounts under our revolving credit facility could limit our ability to fund our future growth and operations. Based on current market conditions, we expect that net cash provided by operating activities and borrowings under our revolving credit facility will be sufficient to finance our operating expenditures, capital expenditures and scheduled interestother contractual cash obligations, including our debt obligations. However, if net cash provided by operating activities and debt repayments through December 31, 2016; however, to the extent theyborrowings under our revolving credit facility are not sufficient, we may seek additional debt or equity financing. Additionally, our term loan facility matures in November 2017. At or prior to the time the term loan matures, we will be required to refinance it and may enter into one or more new facilities, which could result in higher borrowing costs, issue equity, which would dilute our existing shareholders, or otherwise raise the funds necessary to repay the outstanding principal amount under the term loan.

Contingencies to Archrock.Pursuant to the separation and distribution agreement, EESLP contributed to a subsidiary of Archrock the right to receive payments based on a notional amount corresponding to payments received by our subsidiaries from PDVSA Gas in respect of the sale of our and our joint ventures’ previously nationalized assets promptly after such amounts are collected by our subsidiaries until Archrock’s subsidiary has received an aggregate amount of such payments up to the lesser of (i) $125.8 million, plus the aggregate amount of all reimbursable expenses incurred by Archrock and its subsidiaries in connection with recovering any PDVSA Gas default installment payments following the completion of the Spin-off or (ii) $150.0 million. Our balance sheets do not reflect this contingent liability to Archrock or the amount payable to us by PDVSA Gas as a receivable. Pursuant to the separation and distribution agreement, we transferred cash of $19.7 million and $49.2 million to Archrock during the years ended December 31, 2017 and 2016, respectively. The transfers of cash were recognized as reductions to additional paid-in capital in our financial statements. As of December 31, 2015,2017, the remaining principal amount due to us from PDVSA Gas in respect of the sale of our and our joint ventures’ previously nationalized assets was approximately $79$21 million.

Pursuant to the separation and distribution agreement, EESLP (in the case of debt offerings) or Exterran Corporation (in the case of equity issuances) will use its commercially reasonable efforts to complete one or more unsecured debt offerings or equity issuances resulting in aggregate gross cash proceeds of at least $250.0 million on the terms described in the Credit Agreement (such transaction, a “qualified capital raise”) on or before the maturity date of our $245.0 million term loan facility. In connection with the Spin-off, EESLP contributed to a subsidiary of Archrock the right to receive, promptly following the occurrence of a qualified capital raise, a $25.0 million cash payment. Our balance sheets do not reflect this contingent liability to Archrock.

Unrestricted Cash.Of our $29.0$49.1 million unrestricted cash balance at December 31, 2015, $28.52017, $25.0 million was held by our non-U.S. subsidiaries. We have not provided for U.S. federal income taxes on indefinitely (or permanently) reinvested cumulative earnings of approximately $599.8 million generated by our non-U.S. subsidiaries as of December 31, 2015. In the event of a distribution of earnings to the U.S. in the form of dividends, we may be subject to both foreign withholding taxes and U.S. federal income taxes net of allowable foreign tax credits.taxes. We do not believe that the cash held by our non-U.S. subsidiaries has an adverse impact on our liquidity because we expect that the cash we generate in the U.S. and, the available borrowing capacity under our revolving credit facility as well asand the repayment of intercompany liabilities from our non-U.S. subsidiaries will be sufficient to fund the cash needs of our U.S. operations for the foreseeable future.

In recent years, Argentina’s regulations have at times restricted foreign exchange, including exchanging Argentine pesos for U.S. dollars in certain cases, and during these periods we have been unable to freely repatriate cash from Argentina. In late 2015, following the election
45

Table of a new president, some of the currency restrictions were lifted and we have been able to exchange Argentine pesos for U.S. dollars at market rates. However, if we experience restrictions in the future, the cash flow from our operations in Argentina may not be a reliable source of funding for our operations outside of Argentina, which could limit our ability to grow. Restrictions on our ability to exchange Argentine pesos for U.S. dollars subject us to risk of currency devaluation on future earnings in Argentina. During the years ended December 31, 2015 and 2014, we used Argentine pesos to purchase certain short term investments in Argentine government issued U.S. dollar denominated bonds. The effective peso to U.S. dollar exchange rate embedded in the purchase price of $18.4 million and $24.3 million of bonds purchased during the years ended December 31, 2015 and 2014, respectively, resulted in our recognition of a loss of $4.9 million and $6.5 million, respectively, which is included in other (income) expense, net, in our statements of operations. In future periods, we may seek to use Argentine pesos to purchase certain short-term investments in Argentine government issued U.S. dollar denominated bonds, which may result in transaction losses due to the effective peso to U.S. dollar exchange rate embedded in the purchase price of such bonds. As of December 31, 2015, $8.1 million of our cash was in Argentina.Contents


Dividends.  We do not currently anticipate paying cash dividends on our common stock. We currently intend to retain our future earnings to support the growth and development of our business. The declaration of any future cash dividends and, if declared, the amount of any such dividends, will be subject to our financial condition, earnings, capital requirements, financial covenants, applicable law and other factors our board of directors deems relevant.

The principal amount of $12.3 million due in November 2016 under the term loan facility is classified as long-term in our balance sheet at December 31, 2015 because we have the intent and ability to refinance the current principal amount due with borrowings under our existing revolving credit facility.

AtAs of December 31, 2015, $14.92017, $20.5 million of unrecognized tax benefits (including discontinued operations) have been recorded as liabilities in accordance with the accounting standard for income taxes related to uncertain tax positions, and we are uncertain as to if or when such amounts may be settled. Related to these unrecognized tax benefits, we have also recorded a liability for potential penalties and interest (including discontinued operations) of $3.0$4.3 million.

Indemnifications. In conjunction with, and effective as of the completion of, the Spin-off, we entered into the separation and distribution agreement with Archrock, which governs, among other things, the treatment between Archrock and us of aspects relating to certain aspects of indemnification, insurance, confidentiality and cooperation. Generally, the separation and distribution agreement provides for cross-indemnities principally designed to place financial responsibility for the obligations and liabilities of our business with us and financial responsibility for the obligations and liabilities of Archrock’s business with Archrock. Pursuant to the agreement, we and Archrock will generally release the other party from all claims arising prior to the Spin-off that relate to the other party’s business.business, subject to certain exceptions. Additionally, in conjunction with, and effective as of the completion of, the Spin-off, we entered into the tax matters agreement with Archrock. Under the tax matters agreement and subject to certain exceptions, we are generally liable for, and indemnify Archrock against, taxes attributable to our business, and Archrock is generally liable for, and indemnify us against, all taxes attributable to its business. We are generally liable for, and indemnify Archrock against, 50% of certain taxes that are not clearly attributable to our business or Archrock’s business. Any payment made by us to Archrock, or by Archrock to us, is treated by all parties for tax purposes as a nontaxable distribution or capital contribution, respectively, made immediately prior to the Spin-off.

Off-Balance Sheet Arrangements

We have no material off-balance sheet arrangements.

Effects of Inflation

Our revenues and results of operations have not been materially impacted by inflation in the past three fiscal years.

Critical Accounting Policies, Practices and Estimates

This discussion and analysis of our financial condition and results of operations is based upon the Financial Statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates and accounting policies, including those related to bad debt, inventories, fixed assets, investments, intangible assets, income taxes, revenue recognition, and contingencies and litigation. We base our estimates on historical experience and on other assumptions that we believe are reasonable under the circumstances. The results of this process form the basis of our judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions, and these differences can be material to our financial condition, results of operations and liquidity. We describe our significant accounting policies more fully in See Note 2 to our Financial Statements.Statement for a summary of significant accounting policies.

Allowances and Reserves

We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. The determination of the collectability of amounts due from our customers requires us to use estimates and make judgments regarding future events and trends, including monitoring our customers’ payment history and current creditworthiness to determine that collectibility is reasonably assured, as well as consideration of the overall business climate in which our customers operate. Inherently, these uncertainties require us to make judgments and estimates regarding our customers’ ability to pay amounts due to us in order to determine the appropriate amount of valuation allowances required for doubtful accounts. We review the adequacy of our allowance for doubtful accounts quarterly. We determine the allowance needed based on historical write-off experience and by evaluating significant balances aged greater than 90 days individually for collectibility. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. During the years ended December 31, 2015, 20142017, 2016 and 2013,2015, we recorded bad debt expense of $3.5$0.9 million, $0.6$3.0 million and $2.3$3.3 million, respectively. A five percent change in theOur allowance for doubtful accounts would have had an impact on income before income taxeswas approximately 2% and 3% of approximately $0.1 million during the year endedour gross accounts receivable balance at December 31, 2015.2017 and 2016, respectively.

Inventory is a significant component of current assets and is stated at the lower of cost or market.and net realizable value. This requires us to record provisions and maintain reserves for excess,obsolete and slow moving and obsolete inventory. To determine these reserve amounts, we regularly review inventory quantities on hand and compare them to estimates of future product demand, market conditions and production requirements. These estimates and forecasts inherently include uncertainties and require us to make judgments regarding potential outcomes. During 2015, 20142017, 2016 and 2013,2015, we recorded $15.6$1.3 million, $3.2$0.8 million and $0.6$15.6 million, respectively, in inventory write-downs and reserves for inventory which was obsolete excess or carried at a price above market value.slow moving. As discussed further in Note 1415 to the Financial Statements, during the year ended December 31, 2015, we recorded restructuring and other charges of $8.7 million related to inventory write-downs associated with restructuring activities. Significant or unanticipated changes to our estimates and forecasts could impact the amount and timing of any additional provisions for excessobsolete or obsoleteslow moving inventory that may be required. A five percent change in thisOur reserve for obsolete and slow moving inventory reservewas approximately 11% of our gross raw materials inventory balance would have had an impact on income before income taxes of approximately $0.7 million during the year endedat December 31, 2015.2017 and 2016.

Depreciation

Property, plant and equipment areis carried at cost. Depreciation for financial reporting purposes is computed on thea straight-line basis using estimated useful lives and salvage values, including idle assets in our active fleet. The assumptions and judgments we use in determining the estimated useful lives and salvage values of our property, plant and equipment reflect both historical experience and expectations regarding future use of our assets. We periodically analyze our estimates of useful lives of our property, plant and equipment to determine if the depreciable periods and salvage values continue to be appropriate. The use of different estimates, assumptions and judgments in the establishment of property, plant and equipment accounting policies, especially those involving their useful lives, would likely result in significantly different net book values of our assets and results of operations. In the fourth quarter of 2017, we evaluated the estimated useful lives and salvage values of our property, plant and equipment. As a result of this evaluation, we changed the useful lives and salvage values for our compression equipment from a maximum useful life of 30 years to 23 years and a maximum salvage value of 20% to 15% based on expected future use. During the year ended December 31, 2017, we recorded a $1.2 million increase in depreciation expense as a result of these changes in useful lives and salvage values. Additionally, these policy changes are expected to increase our depreciation expense, relative to the previous depreciation schedule of the impacted compression equipment, for the year ended December 31, 2018 by approximately $9.0 million.

Long-Lived Assets

We review long-lived assets, including property, plant and equipment and identifiable intangibles that are being amortized, for impairment whenever events or changes in circumstances, including the removal of compressor units from our active fleet, indicate that the carrying amount of an asset may not be recoverable. Compressor units in our active fleet that were idle as of December 31, 20152017 comprise approximately 217,000 horsepower with a net book value of approximately $71.5$77.7 million. The determination that the carrying amount of an asset may not be recoverable requires us to make judgments regarding long-term forecasts of future revenue and costs related to the assets subject to review. Specifically forFor idle compression units that are removed from the active fleet and that will be sold to third parties as working compression units, significant assumptions include forecasted sale prices based on future market conditions and demand, forecasted costcosts to maintain the assets until sold and the forecasted length of time necessary to sell the assets. These forecasts are uncertain as they require significant assumptions about future market conditions. Significant and unanticipated changes to these assumptions could require a provision for impairment in a future period. Given the nature of these evaluations and their application to specific assets and specific times, it is not possible to reasonably quantify the impact of changes in these assumptions. An impairment loss exists when estimated undiscounted cash flows expected to result from the use of the asset and its eventual disposition are less than its carrying amount. When necessary, an impairment loss is recognized and represents the excess of the asset’s carrying value as compared to its estimated fair value and is charged to the period in which the impairment occurred.

Income Taxes

Our income tax expense,provision, deferred tax assets and liabilities and reserves for unrecognized tax benefits reflect management’s best assessment of estimated current and future taxes to be paid. We operate in approximately 30 countries and, as a result, are subject to income taxes in both the U.S. and numerous foreign jurisdictions. For periods prior to the Spin-off, we determined our tax provision on a separate return, stand-alone basis. We and our subsidiaries file consolidated and separate income tax returns in the U.S. federal jurisdiction and in numerous state and foreign jurisdictions. In addition, certain of our operations were historically included in Archrock’s consolidated income tax returns in the U.S. federal and state jurisdictions. Our tax provision for periods prior to the Spin-off was determined on a separate return, stand-alone basis. Prior to the Spin-off, differencesDifferences between the separate return method utilized and Archrock’s U.S. income tax returns and cash flows attributable to income taxes for our U.S. operations were recognized as distributions to, or contributions from, parent within parent equity. Significant judgments and estimates are required in determining our consolidated income tax expense.provision.

Deferred income taxes arise from temporary differences between the financial statement carrying amounts and the tax basis of assets and liabilities. In evaluating our ability to recover our deferred tax assets within the jurisdiction from which they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies and results of recent operations. In projecting future taxable income, we begin with historical results adjusted for the results of discontinued operations and changes in accounting policies and incorporate assumptions including the amount of future U.S. federal, state and foreign pretax operating income, the reversal of temporary differences and the implementation of feasible and prudent tax-planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates we are using to manage the underlying businesses. In evaluating the objective evidence that historical results provide, we consider three years of cumulative operating income (loss).

Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the future. Management is not aware of any such changes that would have a material effect on the Company’s financial position, results of operations or cash flows. The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in a multitude of jurisdictions across our global operations.

The accounting standard for income taxes provides that a tax benefit from an uncertain tax position may beis only recognized when it is more likely than notmore-likely-than-not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, on the basis of the technical merits. In addition, guidance is provided on measurement, derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. We adjust these liabilitiesreserves for unrecognized tax benefits when our judgment changes as a result of the evaluation of new information not previously available. Because of the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from our current estimate of the tax liabilities. These differences will be reflected as increases or decreases to income tax expenseprovision in the period in which new information is available.

We consider the earnings of certainour non-U.S. subsidiaries to be indefinitely invested outside the U.S. on the basis of estimates that future domestic cash generation and available borrowing capacity under our revolving credit facility, as well as the repayment of intercompany liabilities from our non-U.S. subsidiaries, will be sufficient to meet future domestic cash needs. We have not recorded a deferred tax liability related to these unremitted foreign earnings as it is not practicable to estimate the amount of unrecognized deferred tax liabilities. Should we decide to repatriate any unremitted foreign earnings, we would have to adjust the income tax provision in the period we determined that such earnings will no longer be indefinitely invested outside the U.S.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation. The Tax Reform Act makes broad and complex changes to the U.S. tax code, including, but not limited to, (1) reducing the U.S. federal corporate tax rate from 35% to 21%; (2) requiring companies to pay a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries; (3) generally eliminating U.S. federal income taxes on dividends from foreign subsidiaries; (4) requiring a current inclusion in U.S. federal taxable income of certain earnings of controlled foreign corporations; (5) eliminating the corporate AMT and changing how existing AMT credits can be realized; (6) creating the base erosion anti-abuse tax, a new minimum tax; (7) creating a new limitation on deductible interest expense; and (8) changing rules related to uses and limitations of net operating loss carryforwards created in tax years beginning after December 31, 2017. Guidance under U.S. GAAP requires that the impact of tax legislation be recognized in the period in which the law was enacted.

In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118, which addresses how a company recognizes provisional amounts when a company does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete its accounting for the effect of the changes in the Tax Reform Act. The measurement period ends when a company has obtained, prepared and analyzed the information necessary to finalize its accounting, but cannot extend beyond one year.

While we recorded provisional estimates of the impact of the Tax Reform Act, the final impact may differ from these estimates, due to, among other things, changes in our interpretations and assumptions, additional guidance that may be issued by the government and actions we may take as a result of these enacted tax laws. We are continuing to analyze additional information to determine the final impact as well as other impacts of the Tax Reform Act. Any adjustments recorded to the provisional amounts will be included in income from operations as an adjustment to our 2018 financial statements. For further information on the tax impacts of the Tax Reform Act, see Note 16 to the Financial Statements.

Revenue Recognition — Percentage-of-Completion Accounting

We recognize revenue and profit for our product sales operations as work progresses on long-term contracts using the percentage-of-completion method when the applicable criteria are met. During the years ended December 31, 2015, 20142017, 2016 and 2013,2015, we recognized approximately 74%87%, 73%80% and 77%70%, respectively, of our total product sales revenues from third parties using the percentage-of-completion method. The percentage-of-completion method depends largely on the ability to make reasonably dependable estimates related to the extent of progress toward completion of the contract, contract revenues and contract costs. Recognized revenues and profit are subject to revisions as the contract progresses to completion. Revisions in profit estimates are charged to income in the period in which the facts that give rise to the revision become known. The typical duration of these projects is three to 24 months. If we determine that a contract will result in a loss, we record a provision for the entire amount of the estimated loss in the period in which suchthe loss is identified. Due to the long-term nature of some of our jobs,projects, developing the estimates of costcosts often requires significant judgment.

We estimate percentage-of-completion for compressor and accessoryproduction and processing equipment product sales on a direct labor hour to total labor hour basis. This calculation requires management to estimate the number of total labor hours required for each project and to estimate the profit expected on the project. Production and processing equipment product sales percentage-of-completion is estimated using the direct labor hour to total labor hour basis and the cost to total cost basis. The cost to total cost basis requires us to estimate the amount of total costs (labor and materials) required to complete each project. Because we have many product sales projects in process at any given time, we do not believe that materially different results would be achieved if different estimates, assumptions or conditions were used for any single project.

Factors that must be considered in estimating the work to be completed and ultimate profit include labor productivity and availability, the nature and complexity of work to be performed, the impact of change orders, availability of raw materials and the impact of delayed performance. Although we continually strive to accurately estimate our progress toward completion and profitability, adjustments to overall contract revenue and contract costs could be significant in future periods due to several factors including but not limited to, settlement of claims against customers, vendor claims by or against us, customer change orders, changes in cost estimates, changes in project contingencies and settlement of customer claims against us, such as liquidated damage claims. If the aggregate combined cost estimates for uncompleted contracts that are recognized using the percentage-of-completion method in our product sales businessesbusiness had been higher or lower by 1%5% in 2015,2017, our income before income taxes would have decreased or increased by approximately $7.1$15.7 million. AsAccrued loss contract provisions are included in accrued liabilities in our balance sheets.

Table of December 31, 2015, we had recognized approximately $47.4 million in estimated earnings on uncompleted contracts.Contents


Contingencies and Litigation

We are substantially self-insured for workers’ compensation, employer’s liability, property, auto liability, general liability and employee group health claims in view of the relatively high per-incident deductibles we absorb under our insurance arrangements for these risks. In addition, we currently have a minimal amount of insurance on our offshore assets. Losses up to deductible amounts are estimated and accrued based upon known facts, historical trends and industry averages. We review these estimates quarterly and believe such accruals to be adequate. However, insurance liabilities are difficult to estimate due to unknown factors, including the severity of an injury, the determination of our liability in proportion to other parties, the timeliness of reporting of occurrences, ongoing treatment or loss mitigation, general trends in litigation recovery outcomes and the effectiveness of safety and risk management programs. Therefore, if our actual experience differs from the assumptions and estimates used for recording the liabilities, adjustments may be required and would be recorded in the period in which the difference becomes known. As of December 31, 20152017 and 2014,2016, we had recorded approximately $1.6$1.3 million and $2.7$1.1 million, respectively, in insurance claim reserves.

In the ordinary course of business, we are involved in various pending or threatened legal actions. While we are unable to predict the ultimate outcome of these actions, the accounting standard for contingencies requires management to make judgments about future events that are inherently uncertain. We are required to record (and have recorded) a loss during any period in which we believe a loss contingency is probable and can be reasonably estimated. In making determinations of likely outcomes of pending or threatened legal matters, we consider the evaluation of counsel knowledgeable about each matter.

We regularly assess and, if required, establish accruals for income tax as well as non-incomenon-income-based tax contingencies pursuant to the applicable accounting standards that could result from assessments of additional tax by taxing jurisdictions in countries where we operate. Tax contingencies are subject to a significant amount of judgment and are reviewed and adjusted on a quarterly basis in light of changing facts and circumstances considering the outcome expected by management. As of December 31, 20152017 and 2014,2016, we had recorded approximately $21.1$27.6 million and $13.0$24.3 million, respectively, of accruals for tax contingencies (including penalties and interest and discontinued operations). Of these amounts, $18.0$24.8 million and $11.6$21.2 million respectively, are accrued for income taxes as of December 31, 2017 and 2016, respectively, and $2.8 million and $3.1 million and $1.4 million, respectively, are accrued for non-income based taxes.non-income-based taxes as of December 31, 2017 and 2016, respectively. Furthermore, as of December 31, 2017 and 2016, we had an indemnification receivable from Archrock related to non-income-based taxes of $1.5 million and $1.7 million, respectively. If our actual experience differs from the assumptions and estimates used for recording the liabilities, adjustments may be required and would be recorded in the period in which the difference becomes known.

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risks primarily associated with changes in foreign currency exchange rates. We haverates due to our significant international operations. The net assets and liabilities of these operations are exposed to changes in currency exchange rates. These operations may also have net assets and liabilities not denominated in their functional currency, which exposes us to changes in foreign currency exchange rates that impact income. We currently do not have any derivative financial instruments outstanding to mitigate foreign currency risk. In the future, we may utilize derivative instruments to manage the risk of fluctuations in foreign currency exchange rates that could potentially impact our future earnings and forecasted cash flows. We recorded foreign currency losses of $35.4$0.7 million and $7.8foreign currency gains of $6.5 million in our statements of operations during the years ended December 31, 20152017 and 2014,2016, respectively. Our foreign currency gains and losses are primarily due to exchange rate fluctuations related to monetary asset balances denominated in currencies other than the functional currency, including foreign currency exchange rate changes recorded on intercompany obligations. Our material exchange rate exposure relates to intercompany loans to subsidiariesa subsidiary whose functional currencies arecurrency is the Brazilian Real, and the Euro, which loans carried balances of $59.4 million and $9.1$27.7 million U.S. dollars respectively, as of December 31, 2015.

Changes in exchange rates may create gains or losses in future periods to the extent we maintain net assets and liabilities not denominated in the functional currency.

In recent years, Argentina’s regulations have at times restricted foreign exchange, including exchanging Argentine pesos for U.S. dollars in certain cases, and during these periods we were unable to freely repatriate cash from Argentina. In late 2015, following the election of a new president, some of the currency restrictions were lifted and we have been able to exchange Argentine pesos for U.S. dollars at market rates. However, if we experience restrictions in the future, the cash flow from our operations in Argentina may not be a reliable source of funding for our operations outside of Argentina, which could limit our ability to grow. Future restrictions on our ability to exchange Argentine pesos for U.S. dollars would also subject us to risk of currency devaluation on future earnings in Argentina. Following the easing of the restrictions in late 2015, the Argentine peso devalued by 32% against the U.S. dollar. During the year ended December 31, 2015, we recorded a $1.0 million foreign currency gain in our statements of operations from remeasuring foreign currency accounts into the functional currency in Argentina. Prior to the currency restrictions being lifted in Argentina in late 2015, we used Argentine pesos to purchase certain short term investments in Argentine government issued U.S. dollar denominated bonds. The effective peso to U.S. dollar exchange rate embedded in the purchase price of $18.4 million and $24.3 million of bonds purchased during the years ended December 31, 2015 and 2014, respectively, resulted in our recognition of a loss of $4.9 million and $6.5 million, respectively, which is included in other (income) expense, net, in our statements of operations. As of December 31, 2015, $8.1 million of our cash was in Argentina.

As of December 31, 2015, we had $530.0 million of outstanding borrowings that are subject to floating interest rates. Changes in economic conditions outside of our control could result in higher interest rates, thereby increasing our interest expense and reducing the funds available for capital investment, operations or other purposes. A 1% increase in the effective interest rate on our outstanding debt subject to floating interest rates at December 31, 2015 would result in an annual increase in our interest expense of approximately $5.3 million.

Overview

As previously announced on April 26, 2016 our Audit Committee of our Board of Directors determined that it would be necessary for us to restate our consolidated and combined financial statements. The Audit Committee made this determination following consultation with and upon the recommendation of management. Refer to "Part II—Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations" and Note 3, Restatement of Previously Reported Consolidated and Combined Financial Statements, included in "Part IV—Item 15—Exhibits and Financial Statement Schedules" for a more detailed description of the financial statement restatement.

Notwithstanding the existence of the material weaknesses described below, we believe that the consolidated and combined financial statements in this Annual Report fairly present, in all material respects, our financial position, results of operations and cash flows as of the dates, and for the periods, presented, in conformity with GAAP.

Management’s Evaluation of Disclosure Controls and Procedures

DisclosureThe CEO and CFO have reviewed and evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act)Act of 1934, as amended (the “Exchange Act”), as of the end of the fiscal year for which this annual report on Form 10-K is filed. Based on that evaluation, the CEO and CFO have concluded that the current disclosure controls and procedures are designedeffective to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SECthe Securities and Exchange Commission rules and forms, and include controls and procedures designed to ensure that information required to be disclosed by the Company in such informationreports is accumulated and communicated to management, including the CEO and CFO, as appropriate to allow timely decisions regarding required disclosures.

In connection withManagement, including our CEO (principal executive officer) and CFO (principal financial officer), believes the preparation of the Originalconsolidated financial statements included in this Annual Report on Form 10-K fairly represent in February 2016,all material respects our financial condition, results of operations and cash flows at and for the Company’s management, under the supervision of our principal executive officer and former principal financial officer conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of December 31, 2015. Based upon that evaluation, our principal executive officer and former principal financial officer concluded that, as of the end of the period covered by that report, our disclosure controls and procedures (as definedperiods presented in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) were effective.accordance with U.S. GAAP.

Subsequent to the evaluation made in connection with the filing of the Original Form 10-K in February 2016 and in connection with the preparation and filing of the above-described restatement and this Form 10-K/A, our management, with the participation of our principal executive officer and current principal financial officer, re-evaluated the effectiveness of the design and operation of our disclosure controls and procedures. As described below, management has identified material weaknesses in our internal control over financial reporting, which is an integral component of our disclosure controls and procedures. As a result of those material weaknesses, our principal executive officer and current principal financial officer have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) were not effective as of December 31, 2015.

Material Weaknesses inManagement’s Annual Report on Internal Control Over Financial Reporting

Management, under the supervision of our principal executive officer and principal financial officer, is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) and 15d(f) under the Exchange Act). Internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with GAAP, and includes those policies and procedures that: (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding the prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.

Because of the inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

In connection with the preparation and filingOur management conducted an assessment of the above-described restatement and this Form 10-K/A, the Company’s management, including our principal executive officer and current principal financial officer, has determined that there were material weaknesses ineffectiveness of our internal control over financial reporting.

Control Environment, Risk Assessment, Control Activities, Information and Communication and Monitoring

We did not maintain effectivereporting as of December 31, 2017. This assessment was based on the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework (2013 framework). Based on this assessment, management determined that our internal control over financial reporting related to the following areas: control environment, risk assessment, control activities, information and communication and monitoring. In particular, controls related to the following were not designed or operating effectively:was effective as of December 31, 2017.

There was not adequate integration, emphasisOur independent registered public accounting firm has issued a report on the effectiveness of local senior management accountability and management oversight of accounting and financial reporting activities in implementing and maintaining certain accounting practices at Belleli EPC to conform to the Company’s policies and GAAP.

The Company did not modify its controls and testing procedures to sufficiently address its assessment of risks related to Belleli EPC that could significantly impactour internal control over financial reporting by modifying its approach to how those risks should be addressed.

The Company did not implement and maintain the same accounting controls at Belleli EPC, including information and communication controls, as those maintained in the Company’s other operating locations, resulting in internal controls that were not adequate to prevent or detect instances of intentional override of controls, intentional misconduct, or manipulation of cost-to-complete estimates by, or at the direction of, certain former members of Belleli EPC local senior management.

The Company did not maintain a sufficient complement of personnel with appropriate levels of accounting knowledge, experience and training commensurate with the nature and complexity of Belleli EPC’s business.

Corporate monitoring controls over certain foreign operations were not adequate to detect inappropriate accounting practices and were not designed to operate at a sufficient level of precision to detect material misstatements.

The above material weaknesses contributed to material weaknesses at the control-activity level.which is below.

Revenue RecognitionOverview of Belleli EPC Percentage-of-Completion ProjectsPreviously Reported Material Weaknesses

WeIn our Form 10-K for the fiscal year ended December 31, 2016, we disclosed that the Company did not design and maintain effective procedures or controls over accurate recording, presentation and disclosure of revenue and related costs in the application of percentage-of-completion accounting principles to our engineering, procurement and construction projects by Belleli EPC. Various deficiencies were identified in the process that aggregated to a material weakness. Controls relating to the following areas were not designed or operating effectively:

Controls over the determination of estimated cost-to-complete, including the assessment of contingencies and impact of project uncertainties; and

Controls to address the accuracy and completeness of information used to estimate revenue and related costs in the application of percentage-of-completion accounting principles.

The Company also identified material weaknesses in the control environment relating to risk assessment, control activities, information and communication and monitoring controls which contributed to this material weakness.

Existence and Recovery of Brazil Non-Income-Based Tax Receivables

The Company’s controls and procedures around the existence and recovery of Brazilian non-income-based tax receivables were not designed to review the Brazilian non-income-based tax receivables on a regular basis by personnel with appropriate expertise.

The Company also identified material weaknesses in the control environment and corporate monitoring controls, which contributed to this material weakness.

All of the material weaknesses identified by the Company resulted in misstatements to product sales, product sales cost of sales, accounts receivable, costs and estimated earnings in excess of billings on uncompleted contracts, billings on uncompleted contracts in excess of costs and estimated earnings, accrued liabilities, intangibles and other assets, net, and other income.

Management’s Annual Report on Internal Control Over Financial Reporting

This annual report does not include a report of management’s assessment regarding internal control over financial reporting or an attestation report of the Company’s independent registered accounting firm dueand reported material weaknesses. Refer to a transition period established by rules of the SEC for newly public companies.

Remediation of Material WeaknessItem 9A in Internal Control Over Financial Reporting

Our management is committed to the planning and implementation of remediation efforts to address all material weaknesses, as well as to foster continuous improvement in the Company’s internal controls. These remediation efforts, summarized below, are implemented, in the process of being implemented or are planned for implementation, and are intended to address the identified material weaknesses and enhance our overall financial control environment.

In the first quarter of 2016, our management made a decision to exit the Belleli EPC business, which includes Belleli EPC’s engineering, procurement and constructionAnnual Report on Form 10-K for the manufactureyear ended December 31, 2016 for a description of tanks for tank farms and the manufacture of evaporators and brine heaters for desalination plants. Accordingly, Belleli EPC will not enter into any new contracts or orders from any new or existing customers relating to the Belleli EPC business. This departure decision is considered in determining the nature and extent of our Belleli EPC remediation efforts. In addition, Belleli EPC’s prior local senior management responsible for the intentional override of controls and misconduct are no longer employees of Belleli EPC or its affiliates.

During 2016, we made numerous changes throughout our organization and took significant actions to reinforce the importance of a strong control environment, including training and other steps designed to strengthen and enhance our control culture.

Changes in Internal Control over Financial Reporting

Prior to the Spin-off, we relied on certain financial information and resources of Archrock to manage specific aspects of our business and report results. These included investor relations, corporate communications, accounting, tax, legal, human resources, benefit plan administration, benefit plan reporting, general management, real estate, treasury, insurance and risk management, and oversight functions, such as board of directors and internal audit, which includes Sarbanes-Oxley compliance. In conjunction with the Spin-off, we revised and adopted policies, as needed, to meet all regulatory requirements applicable to us as a stand-alone public company. We continue to review and document our internal controls over financial reporting, and may from time to time make changes aimed at enhancing their effectiveness. These efforts may lead to additional changes in our internal control over financial reporting.

Other than those noted above, there were no changes in our internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) during the last fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

The effectiveness of our internal control over financial reporting as of December 31, 2017 has been audited by Deloitte & Touche, LLP, an independent registered public accounting firm, as stated in their attestation report that follows.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of
Exterran Corporation
Houston, Texas

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Exterran Corporation and subsidiaries (the “Company”) as of December 31, 2017, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated statements of operations, comprehensive income (loss), stockholders’ equity, cash flows, and the related notes and schedule listed in the Index at Item 15 (collectively referred to as the “financial statements”) for the year ended December 31, 2017, of the Company and our report dated February 27, 2018, expressed an unqualified opinion on those consolidated financial statements and financial statement schedule.
Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our audits included considerationperforming procedures to assess the risks of internal control overmaterial misstatement of the financial reporting as a basis for designing auditstatements, whether due to error or fraud, and performing procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includesrespond to those risks. Such procedures included examining, on a test basis, evidence supportingregarding the amounts and disclosures in the financial statements, assessingstatements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statement presentation.statements. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated and combined financial statements present fairly, in all material respects, the financial positionEmphasis of the Company as of December 31, 2015 and 2014, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2015, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule when considered in relation to the basic consolidated and combined financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.Matter

As discussed in Note 3 to the consolidated and combined financial statements, the accompanying 2015, 2014 and 2013 consolidated and combined financial statements have been restated to correct misstatements.

As described in Note 1, prior to November 3, 2015 the accompanying consolidated and combined financial statements were derived from the consolidated financial statements and accounting records of Archrock, Inc. The combined financial statements also include expense allocations for certain corporate functions historically provided by Archrock, Inc. These allocations may not be reflective of the actual expense which would have been incurred had the Company operated as a separate entity apart from Archrock, Inc. during the periods prior to November 3, 2015.

We are a market leader in the provision ofnatural gas processing and treatment and compression production and processing products and services, that supportproviding critical midstream infrastructure solutions to customers throughout the production and transportationworld. Outside the United States of oil andAmerica (“U.S.”), we are a leading provider of full-service natural gas throughout the world.contract compression, and a supplier of aftermarket parts and services. We provide these products and services to a global customer base consisting of companies engaged in all aspects of the oil and natural gas industry, including large integrated oil and natural gas companies, national oil and natural gas companies, independent oil and natural gas producers and oil and natural gas processors, gatherers and pipeline operators. We operate in three primary business lines: contract operations, aftermarket services and product sales. In our contract operations business line, we have operations outside of the United States of America (“U.S.”) where we own and operate natural gas compression equipment and crude oil and natural gas production and processing equipment on behalf of our customers.customers outside of the U.S. In our aftermarket services business line, we have operations outside of the U.S. where wesell parts and components and provide operations, maintenance, overhaul, upgrade, commissioning and reconfiguration services to customers outside of the U.S. who own their own compression, production, processing, treating and related equipment. In our product sales business line, we design, engineer, manufacture, install and sell natural gas compression packages as well as equipment used in the production, treating and processing of crude oil and natural gas production and processing equipment for sale to our customers throughout the world and for use in our contract operations business line. In addition, our product sales business line provides engineering, procurement and manufacturing services related to the manufacture of critical process equipment for refinery and petrochemical facilities, the manufacture of tanks for tank farms and the manufacture of evaporators and brine heaters for desalination plants. We also offer our customers, on either a contract operations basis or a sale basis, the engineering, design, project management, procurement and construction services necessary to incorporate our products into production, processing and compression facilities, which we refer to as integrated projects.

Spin-off

On November 3, 2015, Archrock, Inc. (named Exterran Holdings, Inc. prior to November 3, 2015) (“Archrock”) completed the spin-off (the “Spin-off”) of its international contract operations, international aftermarket services (the international contract operations and international aftermarket services businesses combined are referred to as the “international services businesses” and include such activities conducted outside of the U.S.) and global fabrication businesses into an independent, publicly traded company named Exterran Corporation. We refer to the global fabrication business previously operated by Archrock as our product sales business. To effect the Spin-off, on November 3, 2015, Archrock distributed, on a pro rata basis, all of our shares of common stock to its stockholders of record as of October 27, 2015 (the “Record Date”). Archrock shareholders received one share of Exterran Corporation common stock for every two shares of Archrock common stock held at the close of business on the Record Date. Pursuant to the separation and distribution agreement with Archrock and certain of our and Archrock’s respective affiliates, on November 3, 2015, we transferred cash of $532.6 million to Archrock. Our Registration Statement on Form 10, as amended, initially filed with the Securities and Exchange Commission on March 13, 2015, was declared effective on October 21, 2015. On November 4, 2015, Exterran Corporation common stock began “regular-way” trading on the New York Stock Exchange under the stock symbol “EXTN.” Following the completion of the Spin-off, we and Archrock arebecame and continue to be independent, publicly traded companies with separate boards of directors and management.

Basis of Presentation

The accompanying consolidated and combined financial statements of Exterran Corporation included herein have been prepared in accordance with generally accepted accounting principles generally accepted in the U.S. (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (the “SEC”). All financial information presented for periods after the Spin-off represents our consolidated results of operations, financial position and cash flows (referred to as the “consolidated financial statements”) and all financial information for periods prior to the Spin-off represents our combined results of operations, financial position and cash flows (referred to as the “combined financial statements”). Accordingly:

Our consolidated and combined statements of operations, comprehensive income, cash flows and stockholders’ equity for the year ended December 31, 2015 consist of (i) the combined results of Archrock’s international services and product sales businesses for the period between January 1, 2015 and November 3, 2015 and (ii) the consolidated results of Exterran Corporation for periods subsequent to November 3, 2015.

Our combined statements of operations, comprehensive income, cash flows and stockholders’ equity for the years endedconsolidated balance sheets at December 31, 20142017 and 20132016 consist entirely of the combined results of Archrock’s international services and product sales businesses.our consolidated balances.

F-7

Table of Contents



Our consolidated balance sheet at December 31, 2015 consists of the consolidated balances of Exterran Corporation, while at December 31, 2014, it consists entirely of the combined balances of Archrock’s international services and product sales businesses.

The combined financial statements were derived from the accounting records of Archrock and reflect the combined historical results of operations, financial position and cash flows of Archrock’s international services and product sales businesses. The combined financial statements were presented as if such businesses had been combined for periods prior to November 4, 2015. All intercompany transactions and accounts within these statements have been eliminated. Affiliate transactions between the international services and product sales businesses of Archrock and the other businesses of Archrock have been included in the combined financial statements, with the exception of product sales within our wholly owned subsidiary, Exterran Energy Solutions, L.P. (“EESLP”). Prior to the closing of the Spin-off, EESLP also had a fleet of compression units used to provide compression services in the U.S. services business of Archrock. Revenue has not been recognized in the combined statements of operations for the sale of compressor units by us that were used by EESLP to provide compression services to customers of the U.S. services business of Archrock. See Note 1617 for further discussion on transactions with affiliates.
 
The combined financial statements include certain assets and liabilities that have historically been held at the Archrock level but are specifically identifiable or otherwise attributable to us. The assets and liabilities in the combined financial statements have been reflected on a historical cost basis, as immediately prior to the Spin-off all of the assets and liabilities of Exterran Corporation were wholly owned by Archrock. Third party debt of Archrock, other than debt attributable to capital leases, was not allocated to us for any of the periods presented as we were not the legal obligor of the debt and Archrock’s borrowings were not directly attributable to our business. The combined statements of operations alsofor periods prior to the Spin-off include expense allocations for certain functions historically performed by Archrock and not allocated to its operating segments, including allocations of expenses related to executive oversight, accounting, treasury, tax, legal, human resources, procurement and information technology. See Note 1617 for further discussion regarding the allocation of corporate expenses. Additionally, third party debt of Archrock, other than debt attributable to capital leases, was not allocated to us for any of the periods prior to the Spin-off as we were not the legal obligor of the debt and Archrock’s borrowings were not directly attributable to our business.

We refer to the consolidated and combined financial statements collectively as “financial statements,” and individually as “balance sheets,” “statements of operations,” “statements of comprehensive income (loss),” “statements of stockholders’ equity” and “statements of cash flows” herein.

Investments in affiliated entities in which we own more than a 20% interest and do not have a controlling interest are accounted for using the equity method.

2. Significant Accounting Policies (As Restated)

Use of Estimates in the Financial Statements

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amount of assets, liabilities, revenue and expenses, as well as the disclosures of contingent assets and liabilities. Because of the inherent uncertainties in this process, actual future results could differ from those expected at the reporting date. Significant estimates are required for contracts within our products sales segment that are accounted for under the percentage-of-completed method. As of December 31, 2015, we have provided for our estimated costs-to-complete on all of our ongoing contracts. However, it is possible that current estimates could change due to unforeseen events, which could result in adjustments to overall contract costs. Variations from estimated contract performance could result in material adjustments to operating results. Management believes that the estimates and assumptions used are reasonable.

Cash and Cash Equivalents

We consider all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.

Restricted Cash

Restricted cash as of December 31, 2015 and 2014 consists of cash that contractually is not available for immediate use. Restricted cash is presented separately from cash and cash equivalents in our balance sheets and statements of cash flows.

Revenue Recognition

Contract operations revenue is recognized when earned, which generally occurs monthly when service is provided under our customer contracts. Aftermarket services revenue is recognized as products are delivered and title is transferred or services are performed for the customer.

Product sales revenue from third parties is recognized using the percentage-of-completion method when the applicable criteria are met. We estimate percentage-of-completion for compressor and accessory product sales on a direct labor hour to total labor hour basis. We estimate production and processing equipment product sales percentage-of-completion using the direct labor hour to total labor hour basis and the cost to total cost basis. The duration of these projects is typically between three and 24 months. Product sales revenue is recognized using the completed contract method when the applicable criteria of the percentage-of-completion method are not met. Product sales revenue under the completed contract method is recognized upon either delivery to the customer or achievement of substantial completion in accordance with the specifications within the underlying contract, which generally occurs when all significant attributes and components of the product are completed. Prior to the Spin-off, product sales revenue from affiliates was recognized using the completed contract method as the equipment was not guaranteed to be sold to the affiliate until the entities entered into a bill of sale for such equipment which occurred at the completion of the manufacturing process. Subsequent to November 3, 2015, sales to Archrock and Archrock Partners, L.P. (named Exterran Partners, L.P. prior to November 3, 2015) (“Archrock Partners”) are considered sales to third parties. Product sales revenue from a claim is recognized to the extent that costs related to the claim have been incurred, when collection is probable and can be reliably estimated. We estimate the future costs and gross margin on uncompleted contracts related to our product sales contracts. If we determine that a contract will result in a loss, we record a provision for the entire amount of the estimated loss in the period in which such loss is identified.

Concentrations of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist of cash and cash equivalents and accounts receivable. We believe that the credit risk in temporary cash investments is limited because our cash is held in accounts with multiple financial institutions. Trade accounts receivable are due from companies of varying size engaged principally in oil and natural gas activities throughout the world. We review the financial condition of customers prior to extending credit and generally do not obtain collateral for trade receivables. Payment terms are on a short-term basis and in accordance with industry practice. We consider this credit risk to be limited due to these companies’ financial resources, the nature of products and services we provide and the terms of our contract operations customer service agreements.

We maintain allowances for doubtful accounts for estimated losses resulting from our customers’ inability to make required payments. The determination of the collectibility of amounts due from our customers requires us to use estimates and make judgments regarding future events and trends, including monitoring our customers’ payment history and current creditworthiness to determine that collectibility is reasonably assured, as well as consideration of the overall business climate in which our customers operate. Inherently, these uncertainties require us to make judgments and estimates regarding our customers’ ability to pay amounts due to us in order to determine the appropriate amount of valuation allowances required for doubtful accounts. We review the adequacy of our allowance for doubtful accounts quarterly. We determine the allowance needed based on historical write-off experience and by evaluating significant balances aged greater than 90 days individually for collectibility. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. During the years ended December 31, 2015, 2014 and 2013, we recorded bad debt expense of $3.5 million, $0.6 million and $2.3 million, respectively.

Inventory

Inventory consists of parts used for manufacturing or maintenance of natural gas compression equipment and facilities and processing and production equipment and also includes new compression units and production equipment that are held for sale. Inventory is stated at the lower of cost or market using the average-cost method. A reserve is recorded against inventory balances for estimated obsolescence based on specific identification and historical experience.

Table of Contents


Property, Plant and Equipment

Property, plant and equipment are recorded at cost and depreciated using the straight-line method over their estimated useful lives as follows:

Compression equipment, facilities and other fleet assets3 to 30 years
Buildings20 to 35 years
Transportation, shop equipment and other3 to 12 years

Installation costs capitalized on contract operations projects are generally depreciated over the life of the underlying contract. Major improvements that extend the useful life of an asset are capitalized. Repairs and maintenance are expensed as incurred. When property, plant and equipment is sold, retired or otherwise disposed of, the gain or loss is recorded in other (income) expense, net. Interest is capitalized during the construction period on equipment and facilities that are constructed for use in our operations. The capitalized interest is included as part of the cost of the asset to which it relates and is amortized over the asset’s estimated useful life.

Computer Software

Certain costs related to the development or purchase of internal-use software are capitalized and amortized over the estimated useful life of the software, which ranges from three to five years. Costs related to the preliminary project stage and the post-implementation/operation stage of an internal-use computer software development project are expensed as incurred. Capitalized software costs are included in property, plant and equipment, net, in our balance sheets.

Long-Lived Assets

We review long-lived assets, including property, plant and equipment and identifiable intangibles that are being amortized, for impairment whenever events or changes in circumstances, including the removal of compressor units from our active fleet, indicate that the carrying amount of an asset may not be recoverable. An impairment loss exists when estimated undiscounted cash flows expected to result from the use of the asset and its eventual disposition are less than its carrying amount. When necessary, an impairment loss is recognized and represents the excess of the asset’s carrying value as compared to its estimated fair value and is charged to the period in which the impairment occurred. Identifiable intangibles are amortized over the assets’ estimated useful lives.

Deferred Revenue

Deferred revenue is primarily comprised of upfront billings on contract operations jobs, milestone billings related to jobs where revenue is recognized on the completed contract method and billings related to jobs where revenue is recognized on the percentage-of-completion method that have not begun. Upfront payments received from customers on contract operations jobs are generally deferred and amortized over the life of the underlying contract.

Other (Income) Expense, Net

Other (income) expense, net, is primarily comprised of gains and losses from the remeasurement of our international subsidiaries’ net assets exposed to changes in foreign currency rates, short-term investments and the sale of used assets.

Income Taxes

Our operations are subject to U.S. federal, state and local and foreign income taxes. We and our subsidiaries file consolidated and separate income tax returns in the U.S. federal jurisdiction and in numerous state and foreign jurisdictions. In addition, certain of our operations were historically included in Archrock’s consolidated income tax returns in the U.S. federal and state jurisdictions. Our tax provision for periods prior to the Spin-off was determined on a separate return, stand-alone basis. Prior to the Spin-off, differences between the separate return method utilized and Archrock’s U.S. income tax returns and cash flows attributable to income taxes for our U.S. operations were recognized as distributions to, or contributions from, parent within parent equity.


F-10

Table of Contents


We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.

We record net deferred tax assets to the extent we believe these assets will more likely than not be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies and results of recent operations. In the event we were to determine that we would be able to realize our deferred income tax assets in the future in excess of their net recorded amount, we would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. 

We record uncertain tax positions in accordance with the accounting standard on income taxes under a two-step process whereby (1) we determine whether it is more likely than not that the tax positions will be sustained based on the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement with the related tax authority.

Foreign Currency Translation

The financial statements of subsidiaries outside the U.S., except those for which we have determined that the U.S. dollar is the functional currency, are measured using the local currency as the functional currency. Assets and liabilities of these subsidiaries are translated at the rates of exchange in effect at the balance sheet date. Income and expense items are translated at average monthly rates of exchange. The resulting gains and losses from the translation of accounts into U.S. dollars are included in accumulated other comprehensive income in our balance sheets. For all subsidiaries, gains and losses from remeasuring foreign currency accounts into the functional currency are included in other (income) expense, net, in our statements of operations. We recorded a foreign currency loss of $35.4 million, $7.8 million and $3.1 million during the years ended December 31, 2015, 2014 and 2013, respectively. Included in our foreign currency loss was $30.1 million, $3.6 million and $4.3 million of non-cash losses from foreign currency exchange rate changes recorded on intercompany obligations during the years ended December 31, 2015, 2014 and 2013, respectively. Of the foreign currency losses recognized during the year ended December 31, 2015, $29.7 million was attributable to our Brazil subsidiary’s U.S. dollar denominated intercompany obligations and were the result of a currency devaluation in Brazil and increases in our Brazil subsidiary’s intercompany payables during the current year period.

In recent years, Argentina’s regulations have at times restricted foreign exchange, including exchanging Argentine pesos for U.S. dollars in certain cases, and during these periods we were unable to freely repatriate cash generated in Argentina to fund our other operations. In late 2015, following the election of a new president, some of the currency restrictions were lifted and we have been able to exchange Argentine pesos for U.S. dollars at market rates. Prior to the currency restrictions being lifted in Argentina in late 2015, we used Argentine pesos to purchase certain short-term investments in Argentine government issued U.S. dollar denominated bonds. The effective peso to U.S. dollar exchange rate embedded in the purchase price of these bonds resulted in our recognition of a loss during the years ended December 31, 2015 and 2014 of $4.9 million and $6.5 million, respectively, which is included in other (income) expense, net, in our statements of operations.

Financial Instruments

Our financial instruments consist of cash, restricted cash, receivables, payables and debt. At December 31, 2015 and 2014, the estimated fair values of these financial instruments approximated their carrying amounts as reflected in our balance sheets. See Note 12 for additional information regarding the fair value hierarchy.

Recent Accounting Developments

In November 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-17, Balance Sheet Classification of Deferred Taxes. The update simplifies the presentation of deferred taxes by requiring deferred tax assets and liabilities be classified as noncurrent on the balance sheet. For public business entities, this update is effective on a prospective basis for interim and annual periods beginning after December 15, 2016. The guidance may be adopted prospectively or retrospectively and early adoption is permitted. We elected early adoption with retrospective application as permitted by the guidance. Accordingly, we have restated our balance sheet as of December 31, 2014 to reclassify current deferred income tax assets of $48.9 million to noncurrent deferred income tax assets and current deferred income tax liabilities of $0.6 million to noncurrent deferred income tax liabilities. As a result, our working capital as of December 31, 2014 decreased by $48.3 million compared to amounts previously reported.

In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory, which will require an entity to measure inventory at the lower of cost and net realizable value. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. For public business entities, this update is effective on a prospective basis for interim and annual periods beginning after December 15, 2016, with early adoption permitted. We are currently evaluating the impact of this update on our financial statements.
In April 2015, the FASB issued ASU No. 2015-03, Simplifying the Presentation of Debt Issuance Costs. The update requires an entity to present such costs in the balance sheet as a direct deduction from the carrying amount of the related debt liability rather than as an asset. Amortization of the costs will continue to be reported as interest expense. In August 2015, the FASB issued ASU No. 2015-15, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements, which clarifies that the guidance in the previous update does not apply to line-of-credit arrangements. Per the subsequent update, line-of-credit arrangements will continue to defer and present debt issuance costs as an asset and subsequently amortize the deferred debt costs ratably over the term of the arrangement. Upon transition, an entity is required to comply with the applicable disclosures for a change in an accounting principle. The update will be effective for reporting periods beginning after December 15, 2015 on a retrospective basis and early adoption is permitted. We elected early adoption as permitted by the guidance. During the year ended December 31, 2015, we incurred transaction costs of $7.7 million and $5.6 million related to our revolving credit facility and term loan facility, respectively. Debt issuance costs relating to our term loan facility have been presented as a direct deduction from the carrying value of the facility and debt issuance costs relating to our revolving credit facility have been presented as an asset within intangible and other assets, net.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The update outlines a single comprehensive model for companies to use in accounting for revenue arising from contracts with customers and supersedes the most current revenue recognition guidance, including industry-specific guidance. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The update also requires disclosures enabling users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The update will be effective for reporting periods beginning after December 15, 2017, including interim periods within the reporting period. Early adoption is permitted for reporting periods beginning after December 15, 2016. Companies may use either a full retrospective or a modified retrospective approach to adopt this update. We are currently evaluating the potential impact of the update on our financial statements.

3. Restatement of Previously Reported Consolidated and Combined Financial Statements

Subsequent to the filing of our Annual Report on Form 10-K for the year ended December 31, 2015, originally filed with the Securities and Exchange Commission (the “SEC”) on February 26, 2016 (the “Original Filing”), senior management of the Company identified errors relating to the application of percentage-of-completion accounting principles to certain business lines of our subsidiary, Belleli Energy S.r.l. (subsequently renamed Exterran Italy S.r.l.). Such business lines comprise engineering, procurement and construction for the manufacture of tanks for tank farms and the manufacture of evaporators and brine heaters for desalination plants in the Middle East (referred to as “Belleli EPC” or the “Belleli EPC business” herein). Belleli Energy S.r.l. is headquartered in Mantova, Italy, and its operations are based in Dubai, United Arab Emirates. Management promptly reported the matter to the Audit Committee of the Company’s Board of Directors, which immediately retained counsel, who in turn retained a forensic accounting firm, to initiate an internal investigation. As previously disclosed in the Company’s Current Report on Form 8-K filed with the SEC on April 26, 2016, the Company’s management and the Audit Committee of the Board of Directors determined, based on the preliminary results of the internal investigation, that the financial statements and related report of independent registered public accounting firm within the Original Filing should no longer be relied upon as a result of errors, and possible irregularities, relating to the accounting for certain Belleli EPC projects.

As a result of the internal investigation, management identified inaccuracies related to Belleli EPC projects within our product sales segment in estimating the total costs required to complete projects impacting the years ended December 31, 2015, 2014, 2013 and prior (including the unaudited quarterly periods within 2015 and 2014). The application of percentage-of-completion accounting principles on Belleli EPC projects is estimated using the cost to total cost basis, which requires an estimate of total costs (labor and materials) required to complete each project. The cost-to-complete estimates for Belleli EPC projects were incorrectly estimated and at times manipulated by or at the direction of certain former members of Belleli EPC local senior management, resulting in a misstatement of product sales revenue. The inaccurate cost-to-complete estimates for some Belleli EPC projects also resulted in the need to establish and/or increase contract loss provisions for certain projects, and as a result, product sales cost of sales was misstated. Additionally, penalties for liquidated damages on certain projects were not correctly estimated. Furthermore, other errors within product sales cost of sales on Belleli EPC projects were identified, primarily relating to vendor claims, customer warranties and costs being charged to incorrect projects. As a result of the errors and conduct identified, our product sales revenue was overstated by $19.3 million, $28.1 million and $5.7 million during the years ended December 31, 2015, 2014 and 2013, respectively, and our product sales cost of sales was understated by $0.4 million, $9.5 million and $21.0 million during the years ended December 31, 2015, 2014 and 2013, respectively. These errors and inaccuracies also resulted in the misstatement of accounts receivable, costs and estimated earnings in excess of billings on uncompleted contracts, billings on uncompleted contracts in excess of costs and estimated earnings, accrued liabilities and related income tax effects for each of the periods impacted.

We separately identified prior period errors related to the miscalculation and recovery of non-income-based tax receivables owed to us from the Brazilian government as of December 31, 2011. As a result of these errors and since relevant prior periods were being restated, we recorded adjustments to decrease intangible and other assets, net, beginning parent equity and other income by approximately $26.1 million, $17.5 million and $10.7 million, respectively, as of and for the year ended December 31, 2011 and increase other comprehensive income by approximately $2.1 million as of December 31, 2011. These errors also resulted in the misstatement of intangible and other assets, net, other (income) expense, net, and accumulated other comprehensive income in periods subsequent to December 31, 2011.

Along with restating our financial statements to correct the errors discussed above, we recorded adjustments for certain immaterial accounting errors related to the periods covered in this Form 10-K/A.

Contemporaneously with filing the Form 8-K on April 26, 2016, we self-reported the errors and possible irregularities at Belleli EPC to the SEC. Since then, we have been cooperating with the SEC in its investigation of this matter, including responding to a subpoena for documents related to the restatement and compliance with the U.S. Foreign Corrupt Practices Act (“FCPA”), which are also being provided to the Department of Justice at its request. The FCPA related requests in the SEC subpoena pertain to our policies and procedures, information about our third-party sales agents, and documents related to historical internal investigations completed prior to November 2015.

As of the restatement, on April 22, 2016, June 17, 2016, August 24, 2016 and November 22, 2016, we and our wholly owned subsidiary, EESLP, entered into amendments to the Credit Agreement (as amended, the “Amended Credit Agreement”) with Wells Fargo, as the administrative agent, and various financial institutions as lenders.

Under the Amended Credit Agreement, the lenders waived, among other things, (1) any potential event of default arising under the Credit Agreement as a result of the potential inaccuracy of certain representations and warranties regarding our prior period financial information and previously delivered compliance certificate for the 2015 fiscal year and (2) any requirement that EESLP or we make any representations and warranties as to our prior period financial statements and other prior period financial information. The Amended Credit Agreement extended the deadline to no later than February 28, 2017 by which we are required to deliver to the lenders our quarterly reports for the fiscal quarters ended March 31, 2016, June 30, 2016 and September 30, 2016 and the related compliance certificates demonstrating compliance with the financial covenants set forth in the Credit Agreement.

The Amended Credit Agreement also, among other things:
provides that LIBOR loans will bear interest at LIBOR plus 2.75% and base rate loans will bear interest at the Base Rate plus 1.75% until February 28, 2017 (or, if earlier, the date we deliver replacement financial information for our 2015 audited financial statements, together with a replacement compliance certificate);

adds a condition precedent to the borrowing of loans that, after giving effect to the application of the proceeds of each borrowing, our consolidated cash balance (as defined in the Amended Credit Agreement) will not exceed $30,000,000 plus certain other amounts; and

amends the definition of EBITDA to allow adjustments for certain Restructuring Costs and Restatement Costs (in each case as defined in the Amended Credit Agreement) to the extent such costs were incurred during the years ending December 31, 2016 and 2017.

The financial statements included in this Form 10-K/A have been restated to reflect the adjustments described above. The tables below summarize the effects of the restatement on our (i) balance sheets at December 31, 2015 and 2014, (ii) statements of operations for the years ended December 31, 2015, 2014 and 2013 (iii) statements of comprehensive income for the years ended December 31, 2015, 2014 and 2013 (iv) statements of changes in stockholders’ equity for the year ended December 31, 2013 and (v) statements of cash flows for the years ended December 31, 2015, 2014 and 2013. A summary of the effect of the restatement on the statements of changes in stockholders’ equity for the years ended December 31, 2015 and 2014 is not presented because the impact to accumulated deficit and additional paid-in capital on the statements of changes in stockholders’ equity is reflected below in the balance sheet summaries. Additionally, see Note 23 for a summary of the effect of the restatement on our unaudited quarterly periods within 2015 and 2014.

In addition to the restatement of the financial statements, certain information within the following notes to the financial statements and financial statement schedule has been restated to reflect the corrections of errors discussed above as well as to add disclosure language as appropriate:

Note 2. Significant Accounting Policies

Use of Estimates in the Financial Statements

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amount of assets, liabilities, revenue and expenses, as well as the disclosures of contingent assets and liabilities. Because of the inherent uncertainties in this process, actual future results could differ from those expected at the reporting date. Significant estimates are required for contracts within our products sales segment that are accounted for under the percentage-of-completed method. As of December 31, 2017, we have estimated costs-to-complete on all of our ongoing contracts. However, it is possible that current estimates could change due to unforeseen events, which could result in adjustments to overall contract costs. Variations from estimated contract performance could result in material adjustments to operating results. Management believes that the estimates and assumptions used are reasonable.

Cash and Cash Equivalents

We consider all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.

Restricted Cash

Restricted cash as of December 31, 2017 and 2016 consists of cash that contractually is not available for immediate use. Restricted cash is presented separately from cash and cash equivalents in our balance sheets and statements of cash flows.

Revenue Recognition

Contract operations revenue is recognized when earned, which generally occurs monthly when service is provided under our customer contracts. Aftermarket services revenue is recognized as products are delivered and title is transferred or services are performed for the customer.

Table of Contents


Product sales revenue is recognized using the percentage-of-completion method when the applicable criteria are met. We estimate percentage-of-completion for compressor and production and processing equipment product sales on a direct labor hour to total labor hour basis. The duration of these projects is typically between three and 24 months. Product sales revenue is recognized using the completed contract method when the applicable criteria of the percentage-of-completion method are not met. Product sales revenue under the completed contract method is recognized upon either delivery to the customer or achievement of substantial completion in accordance with the specifications within the underlying contract, which generally occurs when all significant attributes and components of the product are completed. Prior to the Spin-off, product sales revenue from affiliates was recognized using the completed contract method as the equipment was not guaranteed to be sold to the affiliate until the entities entered into a bill of sale for such equipment which occurred at the completion of the manufacturing process. Subsequent to November 3, 2015, sales to Archrock and Archrock Partners, L.P. (named Exterran Partners, L.P. prior to November 3, 2015) (“Archrock Partners”) are considered sales to third parties. Product sales revenue from a claim is recognized to the extent that costs related to the claim have been incurred, when collection is probable and can be reliably estimated. We estimate the future costs and gross margin on uncompleted contracts related to our product sales contracts. If we determine that a contract will result in a loss, we record a provision for the entire amount of the estimated loss in the period in which the loss is identified.

Concentrations of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist of cash and cash equivalents and accounts receivable. We believe that the credit risk in temporary cash investments is limited because our cash is held in accounts with multiple financial institutions. We record trade accounts receivable at the amount we invoice our customers, net of allowance for doubtful accounts. Trade accounts receivable are due from companies of varying sizes engaged principally in oil and natural gas activities throughout the world. We review the financial condition of customers prior to extending credit and generally do not obtain collateral for trade receivables. Payment terms are on a short-term basis and in accordance with industry practice. We consider this credit risk to be limited due to these companies’ financial resources, the nature of products and services we provide and the terms of our contract operations customer service agreements.

We maintain allowances for doubtful accounts for estimated losses resulting from our customers’ inability to make required payments. The determination of the collectibility of amounts due from our customers requires us to use estimates and make judgments regarding future events and trends, including monitoring our customers’ payment history and current creditworthiness to determine that collectibility is reasonably assured, as well as consideration of the overall business climate in which our customers operate. Inherently, these uncertainties require us to make judgments and estimates regarding our customers’ ability to pay amounts due to us in order to determine the appropriate amount of valuation allowances required for doubtful accounts. We review the adequacy of our allowance for doubtful accounts quarterly. We determine the allowance needed based on historical write-off experience and by evaluating significant balances aged greater than 90 days individually for collectibility. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. During the years ended December 31, 2017, 2016 and 2015, we recorded bad debt expense of $0.9 million, $3.0 million and $3.3 million, respectively.

Inventory

Inventory consists of parts used for manufacturing or maintenance of natural gas compression equipment and facilities, parts for processing and production equipment, new compression units and production equipment that are held for sale. Inventory is stated at the lower of cost and net realizable value using the average cost method. A reserve is recorded against inventory balances for estimated obsolescence and slow moving items based on specific identification and historical experience.

Property, Plant and Equipment

Property, plant and equipment is recorded at cost and depreciated using the straight-line method over their estimated useful lives as follows:
Compression equipment, facilities and other fleet assets3 to 23 years
(1)
Buildings20 to 35 years
Transportation, shop equipment and other3 to 10 years
(1)
In the fourth quarter of 2017, we evaluated the estimated useful lives and salvage values of our property, plant and equipment. As a result of this evaluation, we changed the useful lives and salvage values for our compression equipment from a maximum useful life of 30 years to 23 years and a maximum salvage value of 20% to 15% based on expected future use. During the year ended December 31, 2017, we recorded a $1.2 million increase in depreciation expense as a result of these changes in useful lives and salvage values.

Installation costs capitalized on contract operations projects are generally depreciated over the life of the underlying contract. Major improvements that extend the useful life of an asset are capitalized. Repairs and maintenance are expensed as incurred. When property, plant and equipment is sold, or otherwise disposed of, the gain or loss is recorded in other (income) expense, net. Interest is capitalized during the construction period on equipment and facilities that are constructed for use in our operations. The capitalized interest is included as part of the cost of the asset to which it relates and is amortized over the asset’s estimated useful life.

Computer Software

Certain costs related to the development or purchase of internal-use software are capitalized and amortized over the estimated useful life of the software, which ranges from three to five years. Costs related to the preliminary project stage and the post-implementation/operation stage of an internal-use computer software development project are expensed as incurred. Capitalized software costs are included in property, plant and equipment, net, in our balance sheets.

Long-Lived Assets

We review long-lived assets such as property, plant and equipment and identifiable intangibles subject to amortization for impairment whenever events or changes in circumstances, including the removal of compressor units from our active fleet, indicate that the carrying amount of an asset may not be recoverable. An impairment loss exists when estimated undiscounted cash flows expected to result from the use of the asset and its eventual disposition are less than its carrying amount. When necessary, an impairment loss is recognized and represents the excess of the asset’s carrying value as compared to its estimated fair value and is charged to the period in which the impairment occurred. Identifiable intangibles are amortized over the assets’ estimated useful lives.

Deferred Revenue

Deferred revenue is primarily comprised of upfront billings on contract operations projects, milestone billings related to projects where revenue is recognized on the completed contract method and billings related to projects that have not begun where revenue is recognized on the percentage-of-completion method. Upfront payments received from customers on contract operations projects are generally deferred and amortized over the life of the underlying contract.

Other (Income) Expense, Net

Other (income) expense, net, is primarily comprised of gains and losses from the remeasurement of our international subsidiaries’ net assets exposed to changes in foreign currency rates, short-term investments and the sale of used assets.

Income Taxes

Our operations are subject to U.S. federal, state and local and foreign income taxes. We and our subsidiaries file consolidated and separate income tax returns in the U.S. federal jurisdiction and in numerous state and foreign jurisdictions. In addition, certain of our operations were historically included in Archrock’s consolidated income tax returns in the U.S. federal and state jurisdictions. Our tax provision for periods prior to the Spin-off was determined on a separate return, stand-alone basis. Prior to the Spin-off, differences between the separate return method utilized and Archrock’s U.S. income tax returns and cash flows attributable to income taxes for our U.S. operations were recognized as distributions to, or contributions from, parent within parent equity.

We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.

We record net deferred tax assets to the extent we believe these assets will more-likely-than-not be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies and results of recent operations. In the event we were to determine that we would be able to realize our deferred income tax assets in the future in excess of their net recorded amount, we would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. 

We record uncertain tax positions in accordance with the accounting standard on income taxes under a two-step process whereby (1) we determine whether it is more-likely-than-not that the tax positions will be sustained based on the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement with the related tax authority.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Reform Act”). We recognize the impact of tax legislation in the period in which the law is enacted. In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118, which addresses how a company recognizes provisional amounts when a company does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete its accounting for the effect of the changes in the Tax Reform Act. Consistent with that guidance, we recognized provisional amounts based upon our interpretation of the tax laws and estimates which require significant judgments. The actual impact of these tax laws may differ from these provisional amounts, possibly materially, due to, among other things, additional analysis, changes in our interpretations and assumptions, additional guidance that may be issued by the government and actions we may take as a result of these enacted tax laws. Any adjustments recorded to the provisional amounts will be included in income from operations as an adjustment to tax expense.

Foreign Currency Translation

The financial statements of our subsidiaries outside the U.S., except those for which we have determined that the U.S. dollar is the functional currency, are measured using the local currency as the functional currency. Assets and liabilities of these subsidiaries are translated at the exchange rates in effect at the balance sheet date. Income and expense items are translated at average monthly exchange rates. The resulting gains and losses from the translation of accounts into U.S. dollars are included in accumulated other comprehensive income in our balance sheets. For all subsidiaries, gains and losses from remeasuring foreign currency accounts into the functional currency are included in other (income) expense, net, in our statements of operations. We recorded foreign currency losses of $0.7 million, foreign currency gains of $6.5 million and foreign currency losses of $35.8 million during the years ended December 31, 2017, 2016 and 2015, respectively. Included in our foreign currency gains and losses were non-cash gains of $0.5 million, $9.3 million and non-cash losses of $30.1 million during the years ended December 31, 2017, 2016 and 2015, respectively, from foreign currency exchange rate changes recorded on intercompany obligations. Of the foreign currency losses recognized during the year ended December 31, 2015, $29.7 million was attributable to our Brazilian subsidiary’s U.S. dollar denominated intercompany obligations and were the result of a currency devaluation in Brazil and increases in our Brazilian subsidiary’s intercompany payables during 2015.

Table of Contents


During the second quarter of 2016, we entered into forward currency exchange contracts with a total notional value of $11.3 million that expired over varying dates through October 31, 2016. We entered into these foreign currency derivatives to offset exchange rate exposure related to intercompany loans to a subsidiary whose functional currency is the Brazilian Real. We did not designate these forward currency exchange contracts as hedge transactions. Changes in fair value and gains and losses on settlement on these forward currency exchange contracts were recognized in other (income) expense, net, in our statements of operations. During the year ended December 31, 2016, we recognized a loss of $0.7 million on forward currency exchange contracts. All of the forward currency exchange contracts that we entered into were settled prior to December 31, 2016.

Argentina’s regulations have at times restricted foreign exchange, including exchanging Argentine pesos for U.S. dollars, and during these periods we were unable to freely repatriate cash generated in Argentina to fund our other operations. In late 2015, some of the currency restrictions were lifted and we have been able to exchange Argentine pesos for U.S. dollars at market rates. Prior to the currency restrictions being lifted in Argentina in late 2015, we used Argentine pesos to purchase certain short-term investments in Argentine government issued U.S. dollar denominated bonds. The effective peso to U.S. dollar exchange rate embedded in the purchase price of these bonds resulted in our recognition of a loss during the year ended December 31, 2015 of $4.9 million, which is included in other (income) expense, net, in our statements of operations.

Recent Accounting Pronouncements

We consider the applicability and impact of all Accounting Standard Updates (“ASUs”). ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position or results of operations.

Recently Adopted Accounting Pronouncements

In July 2015, the Financial Accounting Standards Board (“FASB”) issued ASU 2015-11, Simplifying the Measurement of Inventory, which requires an entity to measure inventory at the lower of cost and net realizable value. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. On January 1, 2017, we adopted this update on a prospective basis. The adoption of this update did not have a material impact on our financial statements.

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718). The update covers such areas as the recognition of excess tax benefits and deficiencies, the classification of those excess tax benefits on the statement of cash flows, an accounting policy election for forfeitures, the amount an employer can withhold to cover income taxes and still qualify for equity classification and the classification of those taxes paid on the statement of cash flows. On January 1, 2017, we adopted this update. Upon adoption, we elected to account for forfeitures as they occur rather than applying an estimated forfeiture rate, which resulted in a cumulative-effect adjustment to accumulated deficit and additional paid-in capital of $0.1 million under the modified retrospective transition method. Additionally, as a result of this adoption, cash flows related to excess tax benefits are now presented as operating activities within the statements of cash flows. The impact of this retrospective adoption was immaterial to the results of the prior year periods.

Recently Issued Accounting Pronouncements Not Yet Adopted

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The update outlines a single comprehensive model for companies to use in accounting for revenue arising from contracts with customers and supersedes the most current revenue recognition guidance, including industry-specific guidance. The core principle of the guidance is that an entity should recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which the entity expects to be entitled for those goods or services. The update also requires disclosures enabling users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Furthermore, as part of Topic 606, the FASB introduced ASC 340-40 Other Assets and Deferred Costs, which provides guidance on the capitalization of contract related costs that are not within the scope of other authoritative literature. The update will be effective for reporting periods beginning after December 15, 2017, including interim periods within the reporting period. Companies may use either a full retrospective or a modified retrospective approach to adopt the updates. We intend to adopt the new guidance on January 1, 2018 using the modified retrospective approach. In preparation for our adoption of the new standard, we have evaluated representative samples of contracts and other forms of agreements with our customers based upon the five-step model specified by the new guidance. We have completed a preliminary assessment of the potential impact the implementation of this new guidance may have on our financial statements. Although our preliminary assessment may change based upon completion of our evaluation, the following summarizes the more significant impacts expected from the adoption of the new standard:
Revenue from installation services within our product sales segment is currently recognized using the completed contract method. Under the new standard, revenue from such services is expected to be recognized over time.
Revenue from overhaul and reconfiguration services within our aftermarket services segment is currently recognized at a point in time. Under the new standard, revenue from such services is expected to be recognized over time.
Sales commissions associated with long-term service contracts are currently expensed in the period the payment is due to the sales agent. Under the new standard, those costs are expected to be capitalized at the contract inception and amortized over the contract term.
Certain costs to fulfill a contract that are currently being expensed as incurred are expected to be capitalized as a contract related costs and amortized over the contract term.

Additionally, the new guidance will require us to enhance our disclosures to provide additional information relating to disaggregated revenue, contract assets and liabilities and remaining performance obligations. As stated above, we have elected to use the modified retrospective approach and the impact of the adoption of Topic 606 that will be recorded as an adjustment to our January 1, 2018 beginning accumulated deficit balance is tentatively estimated to be less than $10.0 million. We are currently evaluating potential changes to our information systems, processes and internal controls to meet the new standard’s reporting and disclosure requirements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The update requires lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by long-term leases. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the statements of operations. The update also requires certain qualitative and quantitative disclosures about the amount, timing and uncertainty of cash flows arising from leases. Lessor accounting will be similar to the current model except for changes made to align with certain changes to the lessee model and the new revenue recognition standard. Existing sale-leaseback guidance will be replaced with a new model applicable to both lessees and lessors. This update is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted. Adoption will require a modified retrospective approach beginning with the earliest period presented. We are currently evaluating the potential impact of the update on our financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326). The update changes the impairment model for most financial assets and certain other instruments, including trade and other receivables, held-to-maturity debt securities and loans, and requires entities to use a new forward-looking expected loss model that will result in the earlier recognition of allowance for losses. This update is effective for annual and interim periods beginning after December 15, 2019, with early adoption permitted. Adoption will require a modified retrospective approach beginning with the earliest period presented. We are currently evaluating the potential impact of the update on our financial statements.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230). The update 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. This update will be effective for reporting periods beginning after December 15, 2017, including interim periods within the reporting period. This update will require adoption on a retrospective basis unless it is impracticable to apply, in which case it would be required to apply the amendments prospectively as of the earliest date practicable. We do not expect the adoption of this update to be material to our financial statements.

Table of Contents



In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. The update requires a reporting entity to recognize the tax expense from intra-entity asset transfers of assets other than inventory in the selling entity’s tax jurisdiction when the transfer occurs, even though the pre-tax effects of that transaction are eliminated in consolidation. Any deferred tax asset that arises in the buying entity’s jurisdiction would also be recognized at the time of the transfer. This update will be effective for reporting periods beginning after December 15, 2017, including interim periods within the reporting period. Adoption will require a modified retrospective approach beginning with the earliest period presented. While we are still evaluating the impact of the new guidance, we currently do not expect the adoption of this update to be material to our financial statements.

In November 2016, the FASB issued ASU 2016-18, Restricted Cash. The guidance requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. This update will be effective for reporting periods beginning after December 15, 2017, including interim periods within the reporting period, using a retrospective transition method to each period presented. This update will result in the inclusion of our restricted cash balances with cash and cash equivalents to reflect total cash in our statements of cash flows. We do not expect the adoption of this update to be material to our financial statements.

In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718). This update provides guidance that clarifies that changes to the terms or conditions of a share-based payment award should be accounted for as modifications. This update will be effective for reporting periods beginning after December 15, 2017, including interim periods within the reporting period, using a prospective method to an award modified on or after the adoption date. We do not expect the adoption of this update to be material to our financial statements.

Note 5.3. Discontinued Operations

In June 2009, Petroleos de Venezuela S.A. (“PDVSA”) commenced taking possession of our assets and operations in a number of our locations in Venezuela, and by the end of the second quarter of 2009, PDVSA had assumed control over substantially all of our assets and operations in Venezuela. The expropriation of our business in Venezuela meets the criteria established for recognition as discontinued operations under GAAP. Therefore, our Venezuelan contract operations business is reflected as discontinued operations in our financial statements.

In March 2010, our Spanish subsidiary filed a request for the institution of an arbitration proceeding against Venezuela with the International Centre for Settlement of Investment Disputes (“ICSID”) related to the seized assets and investments under the agreement between Spain and Venezuela for the Reciprocal Promotion and Protection of Investments and under Venezuelan law. The arbitration hearing occurred in July 2012.

In August 2012, our Venezuelan subsidiary sold its previously nationalized assets to PDVSA Gas, S.A. (“PDVSA Gas”) for a purchase price of approximately $441.7 million. We received an initial payment of $176.7 million in cash at closing, of which we remitted $50.0 million to repay the amount we collected in January 2010 under the terms of an insurance policy we maintained for the risk of expropriation. We received installment payments, including an annual charge, totaling $19.7 million, $38.8 million and $56.6 million during the years ended December 31, 2017, 2016 and 2015, respectively. As of December 31, 2017, the remaining principal amount due to us was approximately $17 million. We have not recognized amounts payable to us by PDVSA Gas as a receivable and will therefore recognize payments received in the future as income from discontinued operations in the periods such payments are received. The proceeds from the sale of the assets are not subject to Venezuelan national taxes due to an exemption allowed under the Venezuelan Reserve Law applicable to expropriation settlements. In addition, and in connection with the sale, we and the Venezuelan government agreed to waive rights to assert certain claims against each other.

In connection with the sale of these assets, we have agreed to suspend the arbitration proceeding previously filed by our Spanish subsidiary against Venezuela pending payment in full by PDVSA Gas of the purchase price for these nationalized assets.

In accordance with the separation and distribution agreement from the Spin-off, a subsidiary of Archrock has the right to receive payments from EESLP, based on a notional amount corresponding to payments received by our subsidiaries from PDVSA Gas in respect of the sale of our previously nationalized assets promptly after such amounts are collected by our subsidiaries. Pursuant to the separation and distribution agreement, we transferred cash of $19.7 million and $38.8 million to Archrock during the years ended December 31, 2017 and 2016, respectively. The transfers of cash were recognized as reductions to additional paid-in capital in our financial statements. See Note 22for further discussion related to our contingent liability to Archrock.

In the first quarter of 2016, we began executing a plan to exit certain Belleli businesses to focus on our core businesses. Specifically, we began marketing for sale the Belleli CPE business comprised of engineering, procurement and manufacturing services related to the manufacture of critical process equipment for refinery and petrochemical facilities (referred to as “Belleli CPE” or the “Belleli CPE business” herein). Belleli CPE met the held for sale criteria and is reflected as discontinued operations in our financial statements for all periods presented. In August 2016, we completed the sale of our Belleli CPE business to Tosto S.r.l. for cash proceeds of $5.5 million. Belleli CPE was previously included in our product sales segment. In conjunction with the planned disposition of Belleli CPE, we recorded impairments of long-lived assets and current assets that totaled $68.8 million during the year ended December 31, 2016. The impairment charges are reflected in income (loss) from discontinued operations, net of tax.

In addition, in the first quarter of 2016, we began executing our exit of the Belleli EPC business that has historically been comprised of engineering, procurement and construction for the manufacture of tanks for tank farms and the manufacture of evaporators and brine heaters for desalination plants in the Middle East (referred to as “Belleli EPC” or the “Belleli EPC business” herein) by ceasing the bookings of new orders. As of the fourth quarter of 2017, we have substantially exited our Belleli EPC business and, in accordance with GAAP, it is reflected as discontinued operations in our financial statements for all periods presented. Although we have reached mechanical completion on all remaining Belleli EPC contracts, we are still subject to risks and uncertainties potentially resulting from warranty obligations, customer or vendors claims against us, settlement of claims against customers, completion of demobilization activities and litigation developments. The facility previously utilized to manufacture products for our Belleli EPC business has been repurposed to manufacture product sales equipment. As such, certain personnel, buildings, equipment and other assets that were previously related to the Belleli EPC business will remain as part of our continuing operations. As a result, activities associated with our ongoing operations at our repurposed facility are included in continuing operations.

Note 8. Assets Held for Sale

As part of our continual strategic review and optimization of our business structure and the service solutions we offer to our customers, we identified certain assets within our products sales business that we expect to sell within the next twelve months. In the fourth quarter of 2017, we classified $20.5 million of current and long-term assets primarily related to inventory and property, plant and equipment, net, as assets held for sale in our balance sheet. We also determined that certain other assets within our product sales business were assessed to have no future benefit to our ongoing operations. In conjunction with the planned disposition and assessment of certain other assets, we recorded an impairment of long-lived assets that totaled $5.1 million to write-down these assets to their approximate fair values. The impairment charges are reflected in long-lived asset impairment in our statements of operations.

Note 9. Investments in Non-Consolidated Affiliates

Investments in affiliates that are not controlled by us where we have the ability to exercise significant influence over the operations are accounted for using the equity method.

We own a 30.0% interest in WilPro Energy Services (PIGAP II) Limited and 33.3% interest in WilPro Energy Services (El Furrial) Limited, which are joint ventures that provided natural gas compression and injection services in Venezuela. In May 2009, PDVSA assumed control over the assets of our Venezuelan joint ventures and transitioned the operations, including the hiring of their employees, to PDVSA. In March 2011, our Venezuelan joint ventures, together with the Netherlands’ parent company of our joint venture partners, filed a request for the institution of an arbitration proceeding against Venezuela with ICSID related to the seized assets and investments.

In March 2012, our Venezuelan joint ventures sold their assets to PDVSA Gas. We received an initial payment of $37.6 million in March 2012, and received installment payments, including an annual charge, totaling $10.4 million and $15.2 million during the years ended December 31, 2016 and 2015, respectively. As of December 31, 2017, the remaining principal amount due to us was approximately $4 million. We have not recognized amounts payable to us by PDVSA Gas as a receivable and will therefore recognize payments received in the future as equity in income of non-consolidated affiliates in our statements of operations in the periods such payments are received. In connection with the sale of our Venezuelan joint ventures’ assets, the joint ventures and our joint venture partners have agreed to suspend their previously filed arbitration proceeding against Venezuela pending payment in full by PDVSA Gas of the purchase price for the assets.

In accordance with the separation and distribution agreement, a subsidiary of Archrock has the right to receive payments from EESLP based on a notional amount corresponding to payments received by our subsidiaries from PDVSA Gas in respect of the sale of our joint ventures’ previously nationalized assets promptly after such amounts are collected by our subsidiaries. Pursuant to the separation and distribution agreement, we transferred cash of $10.4 million to Archrock during the year ended December 31, 2016. The transfer of cash was recognized as a reduction to additional paid-in capital in our financial statements. See Note 22 for further discussion related to our contingent liability to Archrock.

4. Discontinued Operations

In May 2009, the Venezuelan government enacted a law that reserves to the State of Venezuela certain assets and services related to hydrocarbon activities, which included substantially all of our assets and services in Venezuela. The law provides that the reserved activities are to be performed by the State, by the State-owned oil company, Petroleos de Venezuela S.A. (“PDVSA”), or its affiliates, or through mixed companies under the control of PDVSA or its affiliates. The law authorizes PDVSA or its affiliates to take possession of the assets and take over control of those operations related to the reserved activities as a step prior to the commencement of an expropriation process, and permits the national executive of Venezuela to decree the total or partial expropriation of shares or assets of companies performing those services.

In June 2009, PDVSA commenced taking possession of our assets and operations in a number of our locations in Venezuela, and by the end of the second quarter of 2009, PDVSA had assumed control over substantially all of our assets and operations in Venezuela. The expropriation of our business in Venezuela meets the criteria established for recognition as discontinued operations under GAAP. Therefore, our Venezuelan contract operations business is reflected as discontinued operations in our financial statements.

In March 2010, our Spanish subsidiary filed a request for the institution of an arbitration proceeding against Venezuela with the International Centre for Settlement of Investment Disputes (“ICSID”) related to the seized assets and investments under the agreement between Spain and Venezuela for the Reciprocal Promotion and Protection of Investments and under Venezuelan law. The arbitration hearing occurred in July 2012.

In August 2012, our Venezuelan subsidiary sold its previously nationalized assets to PDVSA Gas, S.A. (“PDVSA Gas”) for a purchase price of approximately $441.7 million. We received an initial payment of $176.7 million in cash at closing, of which we remitted $50.0 million to repay the amount we collected in January 2010 under the terms of an insurance policy we maintained for the risk of expropriation. We received installment payments, including an annual charge, totaling $56.6 million, $72.6 million and $69.3 million during the years ended December 31, 2015, 2014 and 2013, respectively. The remaining principal amount due to us of approximately $66 million as of December 31, 2015, is payable in quarterly cash installments through the third quarter of 2016. We have not recognized amounts payable to us by PDVSA Gas as a receivable and will therefore recognize quarterly payments received in the future as income from discontinued operations in the periods such payments are received. The proceeds from the sale of the assets are not subject to Venezuelan national taxes due to an exemption allowed under the Venezuelan Reserve Law applicable to expropriation settlements. In addition, and in connection with the sale, we and the Venezuelan government agreed to waive rights to assert certain claims against each other.

In connection with the sale of these assets, we have agreed to suspend the arbitration proceeding previously filed by our Spanish subsidiary against Venezuela pending payment in full by PDVSA Gas of the purchase price for these nationalized assets.

In accordance with the separation and distribution agreement, a subsidiary of Archrock has the right to receive payments from EESLP based on a notional amount corresponding to payments received by our subsidiaries from PDVSA Gas in respect of the sale of our previously nationalized assets promptly after such amounts are collected by our subsidiaries. See Note 21 for additional discussion related to our contingent liability to Archrock.

In June 2012, we committed to a plan to sell our contract operations and aftermarket services businesses in Canada (“Canadian Operations”) as part of our continued emphasis on simplification and focus on our core businesses. Our Canadian Operations are reflected as discontinued operations in our financial statements. These operations were previously included in our contract operations and aftermarket services business segments. In connection with the planned disposition, we recorded impairment charges totaling $6.4 million during the year ended December 31, 2013. The impairment charges are reflected in income from discontinued operations, net of tax, in our statements of operations.

In July 2013, we completed the sale of our Canadian Operations to Ironline Compression Holdings LLC, an affiliate of Staple Street Capital L.L.C. We received the following consideration for the sale of the Canadian Operations (specified in either U.S. dollars (“$”) or Canadian dollars (“CDN$”)): (i) cash proceeds of $12.3 million, net of transaction expenses, (ii) a note receivable of CDN$8.1 million, (iii) contingent consideration of CDN$5.0 million based upon the Canadian Operations reaching a specified performance threshold prior to December 31, 2016 and (iv) a potential tax refund related to the Canadian Operations of CDN$1.6 million if such amounts are received by the Canadian Operations.

As of December 31, 2015 and 2014, we had inventory reserves of $14.5 million and $8.7 million, respectively. As discussed further in Note 14, during the year ended December 31, 2015, we recorded restructuring and other charges of $8.7 million related to inventory write-downs associated with restructuring activities.

Prior to the Spin-off, product sales revenue from affiliates was recognized using the completed contract method as the equipment was not guaranteed to be sold to the affiliate until the entities entered into a bill of sale for such equipment which occurred at the completion of the manufacturing process. At December 31, 2014, $33.5 million of work in progress inventory related to product sales projects to affiliates. Subsequent to November 3, 2015, sales to Archrock and Archrock Partners are recognized using the percentage-of-completion method.

We own a 30.0% interest in WilPro Energy Services (PIGAP II) Limited and 33.3% interest in WilPro Energy Services (El Furrial) Limited which are joint ventures that provided natural gas compression and injection services in Venezuela. In May 2009, PDVSA assumed control over the assets of our Venezuelan joint ventures and transitioned the operations, including the hiring of their employees, to PDVSA. In March 2011, our Venezuelan joint ventures, together with the Netherlands’ parent company of our joint venture partners, filed a request for the institution of an arbitration proceeding against Venezuela with ICSID related to the seized assets and investments.

In March 2012, our Venezuelan joint ventures sold their assets to PDVSA Gas. We received an initial payment of $37.6 million in March 2012, and received installment payments, including an annual charge, totaling $15.2 million, $14.7 million and $19.0 million during the years ended December 31, 2015, 2014 and 2013, respectively. The remaining principal amount due to us of approximately $13 million as of December 31, 2015, is payable in cash installments through the first quarter of 2016. We have not recognized amounts payable to us by PDVSA Gas as a receivable and will therefore recognize payments received in the future as equity in (income) loss of non-consolidated affiliates in our statements of operations in the periods such payments are received. In January 2016, we received an installment payment, including an annual charge, of $5.2 million. In connection with the sale of our Venezuelan joint ventures’ assets, the joint ventures and our joint venture partners have agreed to suspend their previously filed arbitration proceeding against Venezuela pending payment in full by PDVSA Gas of the purchase price for the assets.

In accordance with the separation and distribution agreement, a subsidiary of Archrock has the right to receive payments from EESLP based on a notional amount corresponding to payments received by our subsidiaries from PDVSA Gas in respect of the sale of our joint ventures’ previously nationalized assets promptly after such amounts are collected by our subsidiaries. See Note 21 for additional discussion related to our contingent liability to Archrock.

Revolving Credit Facility and Term Loan

On July 10, 2015, we and our wholly owned subsidiary, EESLP, entered into a $750.0 million credit agreement (the “Credit Agreement”) with Wells Fargo, as the administrative agent, and various financial institutions as lenders. On October 5, 2015, the parties amended and restated the Credit Agreement to provide for a $925.0 million credit facility, consisting of a $680.0 million revolving credit facility and a $245.0 million term loan facility (collectively, the “Credit Facility”). Availability under theThe Credit Facility was subjectbecame available to the satisfaction of certain conditions precedent, including the consummation of the Spin-offus on or before January 4, 2016 (the date on which those conditions were satisfied, November 3, 2015 is referred(referred to as the “Initial Availability Date”). The revolving credit facility will mature in November 2020 and the term loan facility will mature in November 2017. In accordance with the Credit Agreement, we are required to repay borrowings outstanding under the term loan facility on each anniversary of the Initial Availability Date in an amount equal to the lesser of (i) $12.3 million and (ii) the outstanding principal balance of the term loan facility. The principal amount of $12.3 million due in November 2016 under the term loan facility is classified as long-term in our balance sheet at December 31, 2015 because we have the intent and ability to refinance the current principal amount due with borrowings under our existing revolving credit facility. On November 3, 2015, EESLP incurred approximately $300.0 million of indebtedness under the revolving credit facility and $245.0 million of indebtedness under the term loan facility. Pursuant to the separation and distribution agreement with Archrock and certain of our and Archrock’s respective affiliates, on November 3, 2015, EESLP transferred $532.6 million of net proceeds from borrowings under the Credit Facility to Archrock to allow it to repay a portion of its indebtedness in connection with the Spin-off. In November 2016, we repaid $12.3 million of borrowings outstanding under the term loan facility. In April 2017, we paid the remaining principal amount of $232.8 million due under the term loan facility with proceeds from the 2017 Notes (as defined below) issuance. As a result of the repayment of the term loan facility, we expensed $1.7 million of unamortized deferred financing costs during the year ended December 31, 2017, which is reflected in interest expense in our statements of operations.

As of December 31, 2015,2017, we had $285.0 million in outstanding borrowings and $116.4$39.7 million in outstanding letters of credit under our revolving credit facility. At December 31, 2015,facility and, taking into account guarantees through letters of credit, we had undrawn and available capacity of $278.6$640.3 million under our revolving credit facility. Our Credit Agreement limits our Total Debt to EBITDA ratio (as defined in the Credit Agreement) on the last day of the fiscal quarter to no greater than 4.50 to 1.0. As a result of this limitation, $585.2 million of the $640.3 million of undrawn capacity under our revolving credit facility was available for additional borrowings as of December 31, 2017.

Revolving borrowings under the Credit Facility bear interest at a rate equal to, at our option, either the Base Rate or LIBOR (or EURIBOR, in the case of Euro-denominated borrowings) plus the applicable margin. The applicable margin for revolving borrowings varies (i) in the case of LIBOR loans, from 1.50% to 2.75% and (ii) in the case of Base Rate loans, from 0.50% to 1.75%, and will be determined based on our total leverage ratio pricing grid. “Base Rate” means the highest of the prime rate, the federal funds effective rate plus 0.50% and one-month LIBOR plus 1.00%. UntilPrior to the repayment of the term loan facility, is refinanced in full with the proceeds of certain qualifying unsecured debt or equity issuances, the applicable margin for borrowings under the revolving credit facility will be increased by 1.00% until the first anniversary of the Initial Availability Date and by 1.50% following the first anniversary of the Initial Availability Date. Term loan borrowings under the Credit Facility will bearincurred interest at a rate equal to, at our option, either (1) the Base Rate plus 4.75%, or (2) the greater of LIBOR or 1.00%, plus 5.75%. The weighted average annual interest rate on outstanding borrowings under the revolving credit facility at December 31, 20152016 was 3.1%5.0%. The annual interest rate on the outstanding balance of the term loan facility at December 31, 20152016 was 6.8%.

We and all of our Significant Domestic Subsidiaries (as defined in the Credit Agreement) guarantee EESLP’s obligations under the Credit Facility.revolving credit facility. In addition, EESLP’s obligations under the Credit Facilityrevolving credit facility are secured by (1) substantially all of our assets and the assets of EESLP and our Significant Domestic Subsidiaries located(as defined in the U.S.Credit Agreement), including certain real property, and (2) all of the equity interests of our U.S. restricted subsidiaries (other than certain excluded subsidiaries) (as defined in the Credit Agreement) and 65% of the voting equity interests in certain of our first-tier foreign subsidiaries.

The 2017 Notes are requiredguaranteed by us on a senior unsecured basis. The net proceeds of $367.1 million from the 2017 Notes issuance were used to prepayrepay all of the borrowings outstanding under the term loan facility and revolving credit facility and for general corporate purposes. Additionally, pursuant to the separation and distribution agreement from the Spin-off, EESLP used proceeds from the issuance of the 2017 Notes to pay a subsidiary of Archrock $25.0 million in satisfaction of EESLP’s obligation to pay that sum following the occurrence of a qualified capital raise. The transfer of cash to Archrock’s subsidiary was recognized as a reduction to additional paid-in capital in the second quarter of 2017.

The 2017 Notes have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws, and unless so registered, may not be offered or sold in the U.S. except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws.

Unamortized Debt Financing Costs

During the year ended December 31, 2017, we incurred transaction costs of $7.9 million related to the issuance of the 2017 Notes. These costs are presented as a direct deduction from the carrying value of the 2017 Notes and are being amortized over the term of the 2017 Notes.

Note 12. Fair Value Measurements

The accounting standard for fair value measurements and disclosures establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into the following three broad categories:

Level 1 — Quoted unadjusted prices for identical instruments in active markets to which we have access at the date of measurement.

Level 2 — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. Level 2 inputs are those in markets for which there are few transactions, the prices are not current, little public information exists or prices vary substantially over time or among brokered market makers.

Level 3 — Model derived valuations in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are those inputs that reflect our own assumptions regarding how market participants would price the asset or liability based on the best available information.

(1)
Our estimate of the fair value of the impaired long-lived assets during the years ended December 31, 2017 and 2016 was primarily based on either the expected net sale proceeds compared to other fleet units we sold and/or a review of other units offered for sale by third parties during that time or the estimated component value of the equipment we planned to use at that time.

Our estimate of the fair value of the impaired assets held for sale during the year ended December 31, 2017 was based on the expected proceeds from the sale of the assets.
(3)
Our estimate of the fair value of the impaired assets of Belleli CPE, which were classified as discontinued operations during the year ended December 31, 2016, was based on the proceeds received from the sale of Belleli CPE, net of selling costs.
(4)
Our estimate of the fair value of the note receivable, including annual payments, from the sale of our plant in Argentina during the year ended December 31, 2016 was discounted based on a settlement period of 2.6 years and a discount rate of 5%.
(5)
The fair value of our liability to exit the use of a corporate operating lease relating restructuring activities during the second quarter of 2016 was estimated based on an incremental borrowing rate of 3% and remaining lease payments, net of estimated sublease rentals, through February 2018.

Fair Value of Debt

The fair value of the 2017 Notes was estimated based on model derived calculations using market yields observed in active markets, which are Level 2 inputs. As of December 31, 2017, the carrying amount of the 2017 Notes, excluding unamortized deferred financing costs, of $375.0 million was estimated to have a fair value of $404.0 million. Due to the variable rate nature of our revolving credit facility and term loan facility, the carrying values as of December 31, 2016 approximated their fair values as the rates were comparable to then-current market rates at which debt with similar terms could have been obtained.

Our estimatefinancial instruments also consist of the impaired long-lived assets’ fair value was primarily based on either the expected net sale proceeds compared to other fleet units we recently sold and/or a reviewcash, restricted cash, receivables and payables.

Note 13. Long-Lived Asset Impairment

We review long-lived assets, including property, plant and equipment and identifiable intangibles that are being amortized, for impairment whenever events or changes in circumstances, including the removal of compressor units from our active fleet, indicate that the carrying amount of an asset may not be recoverable.

During the year ended December 31, 2015, we reviewedWe regularly review the future deployment of our idle compression assets used in our contract operations segment for units that wereare not of the type, configuration, condition, make or model that are cost efficient to maintain and operate. Based on this review,During the years ended December 31, 2017, 2016 and 2015, we determined that one idle compressor unit, 62 idle compressor units and 93 idle compressor units, totaling approximately 72,000 horsepowerrespectively, would be retired from the active fleet. The retirement of these units from the active fleet triggered a review of these assets for impairment. As a result, we recorded aasset impairments of $0.6 million, $12.7 million and $19.4 million asset impairmentduring the years ended December 31, 2017, 2016 and 2015, respectively, to reduce the book value of each unit to its estimated fair value. The fair value of each unit was estimated based on either the expected net sale proceeds compared to other fleet units we recently sold and/or a review of other units recently offered for sale by third parties during that time or the estimated component value of the equipment on each compressor unit that we planplanned to use.use at that time.

In the fourth quarter of 2017, we classified certain assets within our product sales business that we expect to sell within the next twelve months as assets held for sale in our balance sheet. We also determined that certain other assets within our product sales business were assessed to have no future benefit to our ongoing operations. In conjunction with the planned disposition and assessment of certain other assets, we recorded an impairment of long-lived assets that totaled $5.1 million to write-down these assets to their approximate fair values.

During the year ended December 31, 2016, we evaluated other assets for impairment and recorded long-lived asset impairments of $1.7 million on these assets.

During the first quarter of 2015, we evaluated a long-term note receivable from the purchaser of our Canadian Operations for impairment. This review was triggered by an offer from the purchaser of our Canadian Operations to prepay the note receivable at a discount to its then current book value. The fair value of the note receivable as of March 31, 2015 was based on the amount offered by the purchaser of our Canadian Operations to prepay the note receivable. The difference between the book value of the note receivable at March 31, 2015 and its fair value resulted in the recording of an impairment of long-lived assets of $1.4 million. In April 2015, we accepted the offer to early settle this note receivable.

Note 14. Restatement Related Charges

During the yearfirst quarter of 2016, our senior management identified errors relating to the application of percentage-of-completion accounting principles to specific Belleli EPC product sales projects. As a result, the Audit Committee of the Company’s Board of Directors initiated an internal investigation, including the use of services of a forensic accounting firm. Management also engaged a consulting firm to assist in accounting analysis and compilation of restatement adjustments. During the years ended December 31, 2014,2017 and 2016, we evaluatedincurred $6.2 million and $30.1 million, respectively, of external costs associated with the future deploymentrestatement of our idle fleetfinancial statements, an ongoing SEC investigation and determinedremediation activities related to retire approximately 20 idle compressor units, representing approximately 18,000 horsepower, previously used to provide services in our contract operations segment. As a result, we performed an impairment review and recorded athe restatement, of which $2.8 million asset impairmentand $11.2 million, respectively, was recovered from Archrock pursuant to reduce the book valueseparation and distribution agreement. We may incur additional cash expenditures related to external legal counsel costs associated with an ongoing SEC investigation surrounding the restatement of each unit to its estimated fair value. The fair valueour financial statements, of each unit was estimated based on the estimated component value of the equipment we plan to use.which a portion may be recoverable from Archrock.

In connection withThe following table summarizes the changes to our fleet review during 2014, we evaluatedaccrued liability balance related to restatement charges for impairment idle units that had been culled from our fleet in priorthe years and were available for sale. Based upon that review, we reduced the expected proceeds from disposition for certain of the remaining units. This resulted in an additional impairment of $1.1 million to reduce the book value of each unit to its estimated fair value.

In July 2013, as part of our continued emphasis on simplification and focus on our core business, we sold the entity that owned our product sales facility in the United Kingdom. As a result, we recorded impairment charges of $11.9 million during the year ended December 31, 2013.2016 and 2017 (in thousands):

14.Note 15. Restructuring and Other Charges

DuringWe incurred restructuring and other charges associated with the Spin-off of $0.6 million, $3.9 million and $15.7 million during the years ended December 31, 2017, 2016 and 2015, respectively. Costs incurred during the years ended December 31, 2017 and 2016 were primarily related to retention awards to certain employees of $0.6 million and $3.1 million, respectively, which were amortized over the required service period of each applicable employee. Costs incurred during the year ended December 31, 2015 we incurred $15.7 million of costs associated with the Spin-off which were related to non-cash inventory write-downs, financial advisor fees of $4.6 million paid at the completion of the Spin-off, non-cash inventory write-downs, expenses of $3.1 million for retention awards to certain employees, a one-time cash signing bonus paid to our new Chief Executive Officer of $2.0 million and costs to start-up certain stand-alone functions of $1.3 million. Non-cash inventory write-downs which primarily related to the decentralization of shared inventory components between Archrock’s North America contract operations business and our international contract operations business totaled $4.7 million during the year ended December 31, 2015, of which approximately $4.2 million related to our contract operations segment and $0.5 million related to our product sales segment. The charges incurred in conjunction with the Spin-off are included in restructuring and other charges in our statements of operations. We currently estimate that we will incur additional one-time expenditures of approximately $5.4 million related to retention awards to certain employees in the form of cash and stock-based compensation through November 2017. Additionally, we estimate that we will incur additional costs of approximately $0.5 million in the first quarter of 2016 related to the start-up of certain stand-alone functions. We expect the majority of the estimated additional charges will result in cash expenditures.

As a result of theunfavorable market conditions in North America, combined with the impact of lower international activity due to customer budget cuts driven by lower oil prices, in the second quarter of 2015, we announced a cost reduction plan primarily focused on workforce reductions and the reorganization of certain facilities. We incurred restructuring and other charges associated with the cost reduction plan of $2.6 million, $18.1 million and $15.6 million during the years ended December 31, 2017, 2016 and 2015, respectively. Cost incurred for employee termination benefits during the year ended December 31, 2017 were $2.1 million. Restructuring and other charges incurred during the year ended December 31, 2016 were primarily related to employee termination benefits and the exit from a leased corporate building. Costs incurred for employee termination benefits during the year ended December 31, 2016 were $14.5 million, of which $9.0 million related to our product sales facilities. Duringsegment. We ceased the use of a corporate building under an operating lease in the second quarter of 2016, and as a result, recorded net charges of $2.9 million during the year ended December 31, 2016. Restructuring and other charges incurred during the year ended December 31, 2015 we incurred $16.4 million of restructuring and other charges as a result of this plan. Included in this amount was $12.4 millionwere primarily related to employee termination benefits, non-cash inventory write-downs and consulting fees and $4.0 million related to non-cash write-downs of inventory.fees. Costs incurred for employee termination benefits during the year ended December 31, 2015 waswere $9.6 million, of which $6.4 million related to our product sales business.segment. The non-cash inventory write-downs of $4.0 million were the result of our decision to exit the manufacturing of cold weather packages, which had historically been performed at a product sales facility in North America we decided to close.close in 2015. These charges are reflected as restructuring and other charges in our statements of operations.

We currently estimate that we will incur additional charges with respecthave substantially completed restructuring activities related to thisthe Spin-off and cost reduction plan of approximately $2.5 million. We expect the majority of the estimatedplan. No additional charges will resultcosts relating to these restructuring activities are expected to be incurred in cash expenditures.future periods. The remaining accrued liability balance at December 31, 2017 primarily relates to contractual lease payments for our previous corporate building that are expected to be paid in early 2018.

15.Note 16. Provision for Income taxes (As Restated)

Prior to the Spin-off, certain of our operations in the U.S. were included in Archrock’s consolidated federal and state tax returns, and therefore our current and deferred tax expenseprovision for applicable periods was computed on a separate return basis. Subsequent to the Spin-off, we file our own consolidated federal and state tax returns in the U.S.

Tax legislation enacted and signed into law in 2017 in the U.S. and in Argentina resulted in changes to the statutory tax rates at which certain deferred tax assets and liabilities are recorded. These rate changes resulted in a current period reconciling items between income tax recorded at the U.S. statutory rate and the company’s provision for income taxes of $15.5 million and $(3.1) million, respectively. In the U.S., the valuation allowance that had been previously recorded was reduced as a result of the U.S. statutory rate changes.

The increases inDuring the year ended December 31, 2017, our Brazil subsidiary entered into two tax programs: 1) the Tax Regularization Program (the “PRT Program”) pursuant to Brazil Provisional Measure No. 766 issued on January 4, 2017 and 2) the Tax Special Regularization Program (the “PERT Program”) pursuant to Brazil Provisional Measure No. 783 issued on May 31, 2017. These programs allow for the partial settling of debts, both income tax debts and non-income-based tax debts, due by November 30, 2016 and April 30, 2017 to Brazil’s Federal Revenue Service for the PRT Program and PERT Program, respectively, with the use of tax credits, including income tax loss carryforwards. A $15.2 million income tax benefit was recorded during the year ended December 31, 2017 attributable to the reversal of valuation allowances against certain deferred tax assets primarily relate to U.S. federal net operating losses, foreign tax credits, research and development credits (the “R&D Credit”) and alternative minimum tax credits allocated to us by Archrock as a result of the Spin-off. Archrock also transferred valuation allowances primarily related to foreignincome tax credits. The increases are due to changing from a separate return, stand-alone basisloss carryforwards that were utilized under the PRT Program and PERT Program, including interest income. Additionally, during the year ended December 31, 2017, we incurred $1.8 million in penalties, which is reflected in other (income) expense, net, in our statements of operations, and $2.4 million in interest expense, which is reflected in interest expense in our statements of operations, attributable to the actual December 31, 2015 balances allocated to us by Archrock pursuant tosettling of non-income-based tax debts in connection with the Internal Revenue Service (“IRS”) consolidated return regulations.PRT Program and the PERT Program.

At December 31, 2015,2017, we had U.S. federal net operating loss carryforwards of approximately $65.9$118.3 million that are available to offset future taxable income. If not used, the carryforwards begin to expire in 2024. We also had approximately $370.8$181.1 million of net operating loss carryforwards in certain foreign jurisdictions (excluding discontinued operations), approximately $228.6$148.0 million of which has no expiration date, $64.2$7.7 million of which is subject to expiration from 20162018 to 2020,2022, and the remainder of which expires in future years through 2035.2037. Foreign tax credit carryforwards of $72.0$92.7 million, R&D Creditresearch and development credits carryforwards of $31.3 million and alternative minimum tax credit carryforwards of $5.1$5.6 million are available to offset future payments of U.S. federal income tax. The foreign tax credits will expire in varying amounts beginning in 2020 and the R&D Creditsresearch and development credits will expire in varying amounts beginning in 2028, whereas the alternative minimum2028. The corporate Alternative Minimum Tax (“AMT”) has been repealed for tax years beginning after December 31, 2017. Companies with AMT credits that have not been utilized may be carried forward indefinitely under current U.S. tax law.

Pursuant to Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the “Code”), utilization of loss carryforwards and credit carryforwards, such as foreign taxclaim a refund in future years for those credits will be subject to annual limitations due to the ownership changes of both Hanover Compressor Company (“Hanover”) and Universal Compression Holdings, Inc. (“Universal”). In general, an ownership change, as defined by Section 382 of the Code, results from transactions increasing the ownership of certain stockholders or public groups in the stock of a corporation by more than 50 percentage points over a three-year period. The merger of Hanover and Universal to form Archrock resulted in such an ownership change for both Hanover and Universal. Our ability to utilize loss carryforwards and credit carryforwards against future U.S. federaleven when no income tax mayliability exists. We expect our existing AMT credits to be limited. The limitations may cause us to pay U.S. federal income taxes earlier; however, we do not currently expect that any loss carryforwardsfully utilized or credit carryforwards will expire as a result of these limitations.refunded by 2021.

We record valuation allowances when it is more likely than notmore-likely-than-not that some portion or all of our deferred tax assets will not be realized. The ultimate realization of the deferred tax assets depends on the ability to generate sufficient taxable income of the appropriate character and in the appropriate taxing jurisdictions in the future. If we do not meet our expectations with respect to taxable income, we may not realize the full benefit from our deferred tax assets which would require us to record a valuation allowance in our tax provision in future years. Management assesses all available positive and negative evidence to estimate our ability to generate sufficient future taxable income of the appropriate character, and in the appropriate taxing jurisdictions, to permit use of our existing deferred tax assets. A significant piece of objective negative evidence is a cumulative loss incurred over a three-year period in a taxing jurisdiction. Prevailing accounting practice is that such objective evidence would limit the ability to consider other subjective evidence, such as our projections for future growth.

AsWe incurred a three-year cumulative loss in the U.S. during 2016. Due to this significant negative evidence of cumulative losses, which outweighed the positive evidence of firm sales backlog and projected future taxable income, we were no longer able to support that it was more-likely-than-not that we will have sufficient taxable income of the appropriate character in the future that will allow us to realize our U.S. deferred tax assets. During the year ended December 31, 2015,2016, we had $72.0 million in foreign tax credit carryforwardrecorded a full valuation allowances against our U.S. deferred tax assets primarily allocatedresulting in an additional charge of $119.8 million, of which 65.5 million related to us from Archrock. Since we do not expect to generate sufficient taxable income and foreign source taxable income following the Spin-off, the foreign tax credit carryforwards will ultimately expire unused. Archrock recorded a valuation allowance to fully offset the foreign tax credit carryforwardU.S. deferred tax assets they allocated to us.that existed at December 31, 2015.

InPursuant to Sections 382 and 383 of the fourth quarterInternal Revenue Code of 2013, a $20.7 million valuation allowance was recorded against the deferred tax assets for Italy, which primarily related to net operating1986, as amended (the “Code”), utilization of loss carryforwards and accrued loss contracts for Belleli EPC projects. Although the net operating losses have an unlimited carryforward period, cumulative losses in recent years and losses expected in the near term result in it no longer being more likely than not that wecredit carryforwards, such as foreign tax credits, will realize the deferred tax assets in the foreseeable future. Duebe subject to annual limitations ondue to the utilizationhistorical ownership changes of Italy net operatingboth Hanover Compressor Company (“Hanover”) and Universal Compression Holdings, Inc.

In general, an ownership change, as defined by Section 382 of the Code, results from transactions increasing the ownership of certain stockholders or public groups in the stock of a corporation by more than 50 percentage points over a three-year period. The merger of Hanover and Universal to form Archrock (formerly Exterran Holdings, Inc.) in August 2007 resulted in such an ownership change for both Hanover and Universal. Our ability to utilize loss carryforwards we would needand credit carryforwards against future U.S. federal income tax may be limited. The limitations may cause us to generate more than $83 million of taxable income in Italy to fully realize the deferred tax assets.

We consider the earnings of approximately $599.8 million generated bycertain of our non-U.S. subsidiaries as of December 31, 2015. Such earnings are from ongoing operations which willto be used to fund international growth. Weindefinitely reinvested, and accordingly, we have not recorded a deferred tax liability related toprovided for taxes on these unremitted foreignearnings. If we were to make a distribution from the unremitted earnings of these subsidiaries, we would be subject to taxes payable to various jurisdictions. If our expectations were to change regarding future tax consequences, we may be required to record additional deferred taxes that could have a material effect on our consolidated statement of financial position, results of operations or cash flows. Due to the timing of the enactment of the Tax Reform Act, as discussed below, it is not practicable to estimate the amount of unrecognizedindefinitely reinvested earnings or the deferred tax liabilities. Inliability related to the event of a distribution of thoseindefinitely reinvested earnings due to the complexities associated with the underlying hypothetical calculations.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation. The Tax Reform Act makes broad and complex changes to the U.S. intax code, including, but not limited to, (1) reducing the formU.S. federal corporate tax rate from 35% to 21%; (2) requiring companies to pay a one-time transition tax on certain unrepatriated earnings of dividends, we may be subject to both foreign withholding taxes andsubsidiaries; (3) generally eliminating U.S. federal income taxes on dividends from foreign subsidiaries; (4) requiring a current inclusion in U.S. federal taxable income of certain earnings of controlled foreign corporations; (5) eliminating the corporate AMT and changing how existing AMT credits can be realized; (6) creating the base erosion anti-abuse tax (“BEAT”), a new minimum tax; (7) creating a new limitation on deductible interest expense; and (8) changing rules related to uses and limitations of net operating loss carryforwards created in tax years beginning after December 31, 2017. Guidance under U.S. GAAP requires that the impact of tax legislation be recognized in the period in which the law was enacted.

In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118, which addresses how a company recognizes provisional amounts when a company does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete its accounting for the effect of the changes in the Tax Reform Act. The measurement period ends when a company has obtained, prepared and analyzed the information necessary to finalize its accounting, but cannot extend beyond one year.

For the year ended December 31, 2017, our provision for income tax included the reversal of previously recorded valuation allowances of $5.6 million against our U.S. AMT carryforwards due to the Tax Reform Act which provides for the cancellation of the AMT and allows for a future refund and/or credit against regular income tax carry forwards. In addition, as a result of the reduction in the U.S. corporate tax rate from 35% to 21%, we recorded a provisional estimate of $15.5 million due to the re-measurement of deferred tax assets and liabilities and recorded a provisional estimate of $10.1 million due to the transition tax on undistributed earnings. Both of these were offset by a tax benefit from the reduction of the valuation allowance previously recorded against our U.S. deferred tax assets.

Finally, both the tax charges associated with the re-measurement of deferred tax assets and liabilities due to the reduction in the corporate tax rate and the transition tax, and the tax benefit associated with the reduction of the valuation allowance represent provisional amounts. The provisional amounts incorporate assumptions made based upon our current interpretation of the Tax Reform Act and may change as we receive additional clarification and implementation guidance. While we are able to make reasonable estimates of the impact of the reduction in corporate rate and the deemed repatriation transition tax, the final impact of the Tax Reform Act may differ from these estimates, due to, among other things, changes in our interpretations and assumptions, additional guidance that may be issued by the government and actions we may take resulting from these enacted tax laws. We are continuing to analyze additional information to determine the final impact as well as other impacts of the Tax Reform Act. Any adjustments recorded to the provisional amounts will be included in income from operations as an adjustment to our 2018 financial statements.

While the Tax Reform Act provides for a territorial tax system, beginning in 2018, it includes two new U.S. tax base erosion provisions: the global intangible low-taxed income (“GILTI”) provisions and the base-erosion and anti-abuse tax (“BEAT”) provisions. The GILTI provisions require us to include foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets in our U.S. income tax credits.return.

Because of the complexity of the new GILTI tax rules, we will continue to evaluate this provision of the Tax Reform Act and the application of ASC 740, Income Taxes. Under U.S. GAAP, we are allowed to make an accounting policy choice of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the “period cost method”) or (2) factoring such amounts into our measurement of our deferred taxes (the “deferred method”). Our selection of an accounting policy with respect to the new GILTI tax rules will depend, in part, on analyzing our global income to determine whether we expect to have future U.S. inclusions in taxable income related to GILTI and, if so, what the impact is expected to be. We are in the process of analyzing the impact of the GILTI tax rules. Therefore, we have not made any adjustments related to potential GILTI tax in our consolidated financial statements and have not made a policy decision regarding whether to record deferred tax on GILTI for the year ended December 31, 2017.

The BEAT provisions in the Tax Reform Act eliminates the deduction of certain base-erosion payments made to related foreign corporations beginning in 2018, and impose a minimum tax if greater than regular tax. We are in the process of analyzing the impact of the BEAT provision but currently do not expect it will have a material impact on our provision for income tax.

We and our subsidiaries file consolidated and separate income tax returns in the U.S. federal jurisdiction and in numerous state and foreign jurisdictions. Certain of our operations were historically included in Archrock’s consolidated income tax returns in the U.S. federal and state jurisdictions. In addition, certain of Archrock’s operations were historically included in our separate income tax returns in state jurisdictions. Under the Code and the related rules and regulations, each corporation that was a member of the Archrock consolidated U.S. federal income tax reporting group during any taxable period or portion of any taxable period ending on or before the effective time of the Spin-off is jointly and severally liable for the U.S. federal income tax liability of the entire Archrock consolidated tax reporting group for that taxable period. In connection with the Spin-off, we entered into a tax matters agreement with Archrock that allocates the responsibility for prior period taxes of the Archrock consolidated tax reporting group between us and Archrock.

We are subject to U.S. federal income tax examinations for tax years beginning from 1997 onward and, early in the second quarter of 2011, the IRS commenced an examination of Archrock’s U.S. federal income tax returns for the tax years 2006, 2008 and 2009. In October 2012, the IRS completed its examination and issued Revenue Agent’s Reports (“RARs”) that reflected an aggregate over-assessment of $0.9 million. All of the adjustments proposed in the RARs were agreed, except for the disallowance of Archrock’s telephone excise tax refund (“TETR”) claims of $0.5 million related to the 2006 tax year, for which Archrock filed protests with the Appeals Division of the IRS (the “IRS Appeals Division”). Archrock settled with the IRS Appeals Division in December 2013 for more than 90% of the TETR claims and received refunds in the first quarter of 2013. The $0.9 million over-assessment was approved for refund by the Joint Committee on Taxation and was received in the third quarter of 2014. We do not expect any tax adjustments from later tax years that would have a material impact on our financial position or results of operations. 

State income tax returns are generally subject to examination for a period of three to five years after filing the returns. However, the state impact of any U.S. federal audit adjustments and amendments remains subject to examination by various states for up to one year after formal notification to the states. As of December 31, 2015,2017, we did not have any state audits underway that would have a material impact on our financial position or results of operations.

We are subject to examination by taxing authorities throughout the world, including major foreign jurisdictions such as Argentina, Brazil Italy and Mexico. With few exceptions, we and our subsidiaries are no longer subject to foreign income tax examinations for tax years before 2006. Several foreign audits are currently in progress and we do not expect any tax adjustments that would have a material impact on our financial position or results of operations.

We believe it is reasonably possible that a decrease of up to $5.0approximately $9 million in unrecognized tax benefits may be necessary on or before December 31, 20162018 due to the cash and non-cash settlement of audits and the expiration of statutes of limitations. However, due to the uncertain and complex application of tax regulations, it is possible that the ultimate resolution of these matters may result in liabilities which could materially differ from these estimates.

Spin Agreements

In connection with the completion of the Spin-off, on November 3, 2015, we entered into several agreements with Archrock and certain subsidiaries of Archrock and, with respect to certain agreements, a subsidiary of Archrock Partners, that govern the Spin-off and the relationship among the parties following the Spin-off, including the following (collectively, the “Spin Agreements”):

The separation and distribution agreement contains the key provisions relating to the separation of our business from Archrock’s business and the distribution of our common stock to its stockholders. The separation and distribution agreement identifies the assets and rights that were transferred, liabilities that were assumed or retained and contracts and related matters that were assigned to us by Archrock or by us to Archrock in the Spin-off and describes how these transfers, assumptions and assignments occurred. Pursuant to the separation and distribution agreement, on November 3, 2015, we transferred net proceeds of $532.6 million from borrowings under the Credit Facility to Archrock to allow for its repayment of a portion of its indebtedness. In addition, the separation and distribution agreement contains certain noncompetition provisions addressing restrictions for three years after the Spin-off on our ability to provide contract operations and aftermarket services in the U.S. and on Archrock’s ability to provide contract operations and aftermarket services outside of the U.S. and to provide products for sale worldwide that compete with our current product sales business, subject to certain exceptions. The separation and distribution agreement also governs the treatment of aspects relating to indemnification, insurance, confidentiality and cooperation. Additionally, the separation and distribution agreement specifies the right of a subsidiary of Archrock to receive payments from EESLP based on a notional amount corresponding to payments received by our subsidiaries from PDVSA Gas in respect of the sale of our and our joint ventures’ previously nationalized assets promptly after such amounts are collected by our subsidiaries and a $25.0 million cash payment from EESLP promptly following the occurrence of a qualified capital raise (as defined in the Credit Agreement). See Note 21 for additional discussion on such contingent liabilities.

The transition services agreement setsset forth the terms on which Archrock providesprovided to us, and we provideprovided to Archrock, on a temporary basis, certain services or functions that the companies historically have shared. Transition services providedshared prior to us by Archrockthe Spin-off. During the year ended December 31, 2016, we recorded selling, general and to Archrock by us may include accounting, administrative payroll, human resources, environmental health and safety, real estate, fleet, financial audit support, legal, tax, treasuryexpense of $0.7 million and other support and corporateincome of $1.3 million associated with services and each service provided at a predetermined rate set forth inunder the transition services agreement. Each service provided under the agreement has its own duration, generally less than one year but not to exceed two years, extension terms and monthly cost, and the transition services agreement will terminate upon cessation of all services provided thereunder. For the period from November 4, 2015 through December 31, 2015, we recorded selling, general and administrative expense of $0.2 million and other income of $0.2 million associated with services under the transition services agreement.

The supply agreement setsset forth the terms under which we provideprovided manufactured equipment, including the design, engineering, manufacturing and sale of natural gas compression equipment, on an exclusive basis to Archrock and Archrock Partners. ThisThe supply agreement has an initialhad a term of two years, subject to certain cancellation clauses, and iswas extendable for additional one year terms by mutual agreement of the parties.parties, of which the parties chose not to extend the agreement. Pursuant to the supply agreement, each of Archrock and Archrock Partners iswas required to purchase their requirements of newly-manufactured compression equipment from us, subject to certain exceptions. For the period fromSubsequent to November 4,3, 2015, through December 31, 2015, we recorded revenue of $14.4 million and $26.7 million from the sale of newly-manufactured compression equipmentsales to Archrock Partners and Archrock, respectively.

These services agreements will continue in effect until terminated by either party on 30 days’ written notice.third parties.

Transactions with Affiliates

All intercompany transactions and accounts within these financial statements have been eliminated. All affiliate transactions occurring prior to the Spin-off between the international services and product sales businesses of Archrock and the other businesses of Archrock have been included in these financial statements. Prior to the Spin-off, sales of newly-manufactured compression equipment from the product sales business of EESLP to Archrock Partners were used in the U.S. services business of Archrock and were made pursuant to an omnibus agreement between the parties and other affiliates of both entities. Through November 3, 2015, per the omnibus agreement, revenue was determined by the cost to manufacture such equipment plus a fixed margin. During the yearsyear ended December 31, 2015, 2014 and 2013, we recorded product sales revenue from affiliates of $154.3 million $233.0 million and $118.4 million, respectively, and cost of sales of $141.9 million $212.2 million and $106.6 million, respectively, from the sale of newly-manufactured compression equipment to Archrock Partners. Subsequent to November 3, 2015, sales to Archrock Partners are considered sales to third parties.

Prior to the closing of the Spin-off, EESLP also had a fleet of compression units used to provide compression services in the U.S. services business of Archrock. Revenue prior to the Spin-off was not recognized in our statements of operations for the sale of compressor units by us that were used by EESLP to provide compression services to customers of the U.S. services business of Archrock. The costcosts of these units were treated as a reduction of parent equity in the balance sheets and a distribution to parent in the statements of cash flows and totaled $32.3 million $59.1 million and $55.2 million during the yearsyear ended December 31, 2015, 2014 and 2013, respectively.2015. Subsequent to November 3, 2015, sales to Archrock are considered sales to third parties.

Allocation of Expenses

For the periods prior to the Spin-off, the statements of operations also includes expense allocations for certain functions performed by Archrock which have not been historically allocated to its operating segments, including allocations of expenses related to executive oversight, accounting, treasury, tax, legal, human resources, procurement and information technology. Included in our selling, general and administrative expense during the yearsyear ended December 31, 2015 2014 and 2013 werewas $46.9 million, $68.3 million and $62.6 million, respectively, of allocated corporate expenses incurred by Archrock prior to the Spin-off. These costs were allocated to us systematically based on specific department function and revenue. Management believes the assumptions underlying the financial statements, including the assumptions regarding allocating expenses from Archrock, are reasonable. Nevertheless, the financial statements may not includebe representative of all of the actual expenses that would have been incurred had we been a stand-alone public company during the periods presented and, consequently, may not reflect our combined results of operations, financial position and cash flows had we been a stand-alone public company during the periods presented. Actual costs that would have been incurred if we had been a stand-alone public company would depend on multiple factors, including organizational structure and strategic decisions made in various areas, including information technology and infrastructure.


F-31



Cash Management

Prior to the closing of the Spin-off, EESLP provided centralized treasury functions for Archrock’s U.S. operations, whereby EESLP regularly transferred cash both to and from U.S. subsidiaries of Archrock, as necessary. In conjunction therewith, the intercompany transactions between our U.S. subsidiaries and the other U.S. subsidiaries of Archrock were considered to be effectively settled in cash in these financial statements for the periods prior to the Spin-off. Intercompany receivables/payables from/to related parties arising from transactions with affiliates and expenses allocated from Archrock described above were included in net distributions to parent in the financial statements.

Net Distributions to Parent

Parent equity, which included retained earnings prior to the Spin-off, represents Archrock’s interest in our recorded net assets. Prior to the Spin-off, all transactions between us and Archrock were presented in the accompanying statementsstatement of stockholders equity as net distributions to parent. As of November 3, 2015, parent equity was converted to common stock and additional paid-in capital.

17.Note 18. Stockholders’ Equity (As Restated)

The Exterran Corporation amended and restated certificate of incorporation authorizes 250.0 million shares of common stock and 50.0 million shares of preferred stock, each with a par value of $0.01 per share. To effect the Spin-off, on November 3, 2015, Archrock distributed 34,286,267 shares of our common stock to its shareholders. Archrock shareholders received one share of Exterran Corporation common stock for every two shares of Archrock common stock held at the close of business on the Record Date. Additionally, certain of Archrock’s common stock awards that were outstanding prior to the Spin-off were converted to Exterran Corporation’s common stock awards on November 3, 2015. The conversion of Archrock restricted stock into Exterran Corporation restricted stock resulted in the issuance of 505,512 shares of our common stock. See Note 1819 for further discussion regarding stock-based compensation.


F-34



Pursuant to the separation and distribution agreement with Archrock and certain of our and Archrock’s respective affiliates, on November 3, 2015, EESLP transferred $532.6 million of net proceeds from borrowings under the Credit Facility to Archrock to allow it to repay a portion of its indebtedness in connection with the Spin-off.

Parent equity, which included retained earnings prior to the Spin-off, represents Archrock’s interest in our recorded net assets. Prior to the Spin-off, all transactions between us and Archrock were presented in the accompanying statements of stockholders’ equity as net distributions to parent. As of November 3, 2015, parent equity was converted to common stock and additional paid-in capital.

Comprehensive Income (Loss)

Components of comprehensive income (loss) are net income (loss) and all changes in stockholders’ equity during a period except those resulting from transactions with owners. Our accumulated other comprehensive income consists of foreign currency translation adjustments.

18.Note 19. Stock-Based Compensation and Awards

2015 Stock Incentive Plan

On October 30, 2015, our compensation committee and board of directors each approved the Exterran Corporation 2015 Stock Incentive Plan (the “2015 Plan”) to provide for the granting of stock options, stock appreciation rights, restricted stock, restricted stock units, performance awards, other stock-based awards and dividend equivalents rights to employees, directors and consultants of Exterran Corporation. The 2015 Plan became effective on November 1, 2015. The 2015 Plan will also governgoverns awards granted under the Archrock, Inc. 2013 Stock Incentive Plan and the Archrock, Inc. 2007 Amended and Restated Stock Incentive Plan which were adjusted into awards denominated in our common stock in accordance with the terms of the employee matters agreement and/or actions taken by our board of directors or the ArchrockArchrock’s board of directors.

Awards granted by Archrock prior to the Spin-off (referred to as “Archrock awards”), which consisted of stock options, restricted stock, restricted stock units and performance units, were generally treated as follows in connection with the Spin-off:

Pre-2015 Awards. Immediately prior to the Spin-off, each outstanding Archrock stock option, restricted stock award, restricted stock unit award and performance unit award granted prior to January 1, 2015, whether vested or unvested, were split into two awards, consisting of an Archrock award and an Exterran Corporation award. For Archrock “incentive stock options” (within the meaning of Section 422 of the Code), the holder of the award had the option to elect, prior to the Spin-off, to convert such options into options denominated in shares of common stock of the applicable holder’s post-spin employer.

2015 Awards. Each Archrock stock option, restricted stock award, restricted stock unit award and performance unit award that was (i) granted in calendar year 2015 and (ii) held by an individual who became our employee or iswas engaged by us following the Spin-off were converted solely into an Exterran Corporation award. Archrock did not grant any stock options in the calendar year 2015 prior to the Spin-off.

In accordance with the anti-dilution provisions set forth in the individual Archrock award agreements, adjustments to the awards were made to ensure, to the extent possible, that the fair value of each award immediately prior to the Spin-off equalsequaled the fair value of each such award immediately following the Spin-off. Adjustment and substitution of awards did not result in additional compensation expense.

Equity awards that were adjusted as described above are generally subject to the same vesting, expiration, performance conditions and other terms and conditions as applied to the underlying Archrock awards immediately prior to the Spin-off.


F-33



Stock-based compensation expense prior to the Spin-off only related to employees directly involved in our operations, and therefore, excluded stock-based compensation expense related to Archrock employees that supported both the international services and product sales businesses and the other businesses of Archrock that it retained after the Spin-off. Stock-based compensation expense subsequent to the Spin-off relates to employees, directors and consultants of Exterran Corporation, and as discussed above, such awards may consist of awards for either our common stock or Archrock’s common stock. Effective on January 1, 2017, we account for forfeitures as they occur rather than applying an estimated forfeiture rate. The following table presents the stock-based compensation expense included in our results of operations (in thousands):

Stock Options

Stock options are granted at fair market value at the grant date, are exercisable according to the vesting schedule established and generally expire no later than tenseven years after the grant date. Stock options generally vest one-third per year on each of the first three anniversaries of the grant date.


F-36



The weighted average grant date fair value for stock options granted during the years ended 2014 and 2013 was $14.47 and $10.19, respectively, and was estimated using the Black-Scholes option valuation model with the weighted average assumptions in the table below. There were no stock options granted during the yearyears ended December 31, 2015. As there were no stock option awards for Exterran Corporation’s common stock granted between November 3, 20152017, 2016 and December 31, 2015, the significant assumptions presented below are the inputs Archrock used to calculate the grant date fair values of stock options granted prior to the Spin-off.

 Years Ended December 31,
 2015 2014 2013
Expected life in yearsN/A 4.5
 4.5
Risk-free interest rateN/A 1.33% 0.66%
VolatilityN/A 46.51% 49.19%
Dividend yieldN/A 1.5% 0.0%

The risk-free interest rate was based on the U.S. Treasury yield curve in effect on the grant date for a period commensurate with the estimated expected life of the stock options. Expected volatility was based on the historical volatility of Archrock’s common stock over the period commensurate with the expected life of the stock options and other factors. The dividend yield was based on Archrock’s annualized dividend rate in effect during the quarter in which the grant was made. At the time of the stock option grants during the year ended December 31, 2013, Archrock had not historically paid any dividends and did not expect to pay any dividends during the expected life of the stock options.2015.

The table below presents the changes in stock option awards for our common stock from November 3, 2015 throughduring the year ended December 31, 2015. Options outstanding on the Spin-off date, November 3, 2015, relate to employees, directors and consultants of us and Archrock.

Intrinsic value is the difference between the market value of our common stock and the exercise price of each stock option multiplied by the number of stock options outstanding for those stock options where the market value exceeds their exercise price. AsThe total intrinsic value of December 31, 2015, we expect $0.2 million of unrecognized compensation cost related to unvested stock options issuedexercised to our employees, directors and consultants, related to options to purchase either our common stock or Archrock’s common stock, to be recognized overduring the weighted-average period of 1.0 years.year ended December 31, 2017 was $0.8 million.

Restricted Stock, Restricted Stock Units, Performance Units, Cash Settled Restricted Stock Units and Cash Settled Performance Units

For grants of restricted stock, restricted stock units and performance units, we recognize compensation expense over the vesting period equal to the fair value of our common stock at the grant date. We remeasure the fair value of cash settled restricted stock units and cash settled performance units and record a cumulative adjustment of the expense previously recognized. Our obligation related to the cash settled restricted stock units and cash settled performance units is reflected as a liability in our balance sheets. Grants of restricted stock, restricted stock units, performance units, cash settled restricted stock units and cash settled performance units generally vest one-third per year on each of the first three anniversaries of the grant date.

Directors’ Stock and Deferral Plan
 
On October 30, 2015, our compensation committee and board of directors each approved the Exterran Corporation 2015 Directors’ Stock and Deferral Plan (the “Director Plan”). Under the Director Plan, which became effective on October 30, 2015, members of our board of directors may elect, on an annual basis, to receive 25%, 50%, 75% or 100% of their retainer and meeting fees (the “Retainer Fees”) in shares of our common stock in lieu of cash. The number of shares of our common stock issued to each director who elects to have a portion of their Retainer Fees paid in shares in lieu of cash is determined by dividing the applicable dollar amount of such portion by the closing sales price per share of our common stock on the last trading day of the quarter. Any portion of the Retainer Fees paid in cash will be paid to the director following the close of the calendar quarter for which such Retainer Fees were earned. Under the Director Plan, members of the board of directors who elect to receive the Retainer Fees in the form of shares may also elect to defer until a later date the receipt of the Retainer Fees that such director has elected to receive in the form of shares.until a later date. The maximum aggregate number of shares of our common stock that may be issued under the Director Plan is 125,000 shares.shares, of which 95,184 shares were available to be issued under the plan as of December 31, 2017. The board of directors will administer the Director Plan and has the authority to make certain equitable adjustments under the Director Plan in the event of certain corporate transactions.

19.Note 20. Net Income (Loss) Per Common Share (As Restated)

Basic net income (loss) per common share is computed using the two-class method, which is an earnings allocation formula that determines net income (loss) per share for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings. Under the two-class method, basic net income (loss) per common share is determined by dividing net income (loss) after deducting amounts allocated to participating securities, by the weighted average number of common shares outstanding for the period. Participating securities include our unvested restricted stock and certain stock settled restricted stock units that have nonforfeitable rights to receive dividends or dividend equivalents, whether paid or unpaid. During periods of net loss from continuing operations, no effect is given to participating securities because they do not have a contractual obligation to participate in our losses.

Diluted net income (loss) per common share is computed using the weighted average number of common shares outstanding adjusted for the incremental common stock equivalents attributed to outstanding options to purchase common stock and non-participating restricted stock units, unless their effect would be anti-dilutive.

To effect the Spin-off, on November 3, 2015, Archrock distributed 34,286,267 shares of our common stock to its stockholders. For the periods prior to November 3, 2015, the average number of common shares outstanding used to calculate basic and diluted net income per common share was based on the shares of our common stock that were distributed on November 3, 2015. The same number of shares was used to calculate basic and diluted net income per common share for these periods since we had no equity awards outstanding prior to November 3, 2015 and we were a wholly owned subsidiary of Archrock prior to the Spin-off date.

Contingencies

See Note 43 and Note 9 for a discussion of our gain contingencies related to assets that were expropriated in Venezuela.

Pursuant to the separation and distribution agreement, EESLP contributed to a subsidiary of Archrock the right to receive payments based on a notional amount corresponding to payments received by our subsidiaries from PDVSA Gas in respect of the sale of our and our joint ventures’ previously nationalized assets promptly after such amounts are collected by our subsidiaries until Archrock’s subsidiary has received an aggregate amount of such payments up to the lesser of (i) $125.8 million, plus the aggregate amount of all reimbursable expenses incurred by Archrock and its subsidiaries in connection with recovering any PDVSA Gas default installment payments following the completion of the Spin-off or (ii) $150.0 million. Our balance sheets do not reflect this contingent liability to Archrock or the amount payable to us by PDVSA Gas as a receivable. Pursuant to the separation and distribution agreement, we transferred cash of $19.7 million and $49.2 million to Archrock during the years ended December 31, 2017 and 2016, respectively. The transfers of cash were recognized as reductions to additional paid-in capital in our financial statements. As of December 31, 2015,2017, the remaining principal amount due to us from PDVSA Gas in respect of the sale of our and our joint ventures’ previously nationalized assets was approximately $79$21 million. In subsequent periods, the recognition of a liability, if applicable, resulting from this contingency to Archrock is expected to impact equity, and as such, is not expected to have an impact on our statements of operations.

Pursuant to the separation and distribution agreement, EESLP (in the case
F-37

Table of debt offerings) or Exterran Corporation (in the case of equity issuances) will use its commercially reasonable efforts to complete one or more unsecured debt offerings or equity issuances resulting in aggregate gross cash proceeds of at least $250.0 million on the terms described in the Credit Agreement (such transaction, a “qualified capital raise”) on or before the maturity date of our $245.0 million term loan facility. In connection with the Spin-off, EESLP contributed to a subsidiary of Archrock the right to receive, promptly following the occurrence of a qualified capital raise, a $25.0 million cash payment. Our balance sheets do not reflect this contingent liability to Archrock. In subsequent periods, the recognition of a liability, if applicable, resulting from this contingency to Archrock is expected to impact equity, and as such, is not expected to have an impact on our statements of operations.Contents


In addition to U.S. federal, state and local and foreign income taxes, we are subject to a number of taxes that are not income-based. As many of these taxes are subject to audit by the taxing authorities, it is possible that an audit could result in additional taxes due. We accrue for such additional taxes when we determine that it is probable that we have incurred a liability and we can reasonably estimate the amount of the liability. As of December 31, 20152017 and 2014,2016, we had accrued $3.1$2.8 million and $1.4$3.1 million, respectively, for the outcomes of non-income basednon-income-based tax audits.audits and had related indemnification receivables from Archrock of $1.5 million and $1.7 million, respectively. We do not expect that the ultimate resolutions of these audits will result in a material variance from the amounts accrued. We do not accrue for unasserted claims for tax audits unless we believe the assertion of a claim is probable, it is probable that it will be determined that the claim is owed and we can reasonably estimate the claim or range of the claim. We do not have any unasserted claims from non-income basednon-income-based tax audits that we have determined are probable of assertion. We also believe the likelihood is remote that the impact of potential unasserted claims from non-income basednon-income-based tax audits could be material to our financial position, but it is possible that the resolution of future audits could be material to our results of operations or cash flows for the period in which the resolution occurs.

Our business can be hazardous, involving unforeseen circumstances such as uncontrollable flows of natural gas or well fluids and fires or explosions. As is customary in our industry, we review our safety equipment and procedures and carry insurance against some, but not all, risks of our business. Our insurance coverage includes property damage, general liability, and commercial automobile liability and other coverage we believe is appropriate. In addition, we have a minimal amount of insurance on our offshore assets. We believe that our insurance coverage is customary for the industry and adequate for our business; however, losses and liabilities not covered by insurance would increase our costs.

Additionally, we are substantially self-insured for workers’ compensation and employee group health claims in view of the relatively high per-incident deductibles we absorb under our insurance arrangements for these risks. Losses up to the deductible amounts are estimated and accrued based upon known facts, historical trends and industry averages.

Contracts Containing Liquidated Damages Provisions

Some of our product sales contracts have schedule dates and performance obligations that if not met could subject us to penalties for liquidated damages. These generally relate to specified activities that must be completed by a set contractual date or by achievement of a specified level of output or throughput. Each contract defines the conditions under which a customer may make a claim for liquidated damages. However, in some instances, liquidated damages are not asserted by the customer, but the potential to do so is used in negotiating or settling claims and closing out the contract. As of December 31, 2015, estimated penalties for liquidated damages of $18.8 million have been recorded in our financial statements, based on our actual or projected failure to meet certain specified contractual milestone dates. We believe that we will be successful in obtaining schedule extensions or other customer-agreed changes that should resolve the potential for additional liquidated damages. Accordingly, we believe that no amounts for these potential liquidated damages in excess of the amounts currently reflected in our financial statements are probable of being incurred by us. However, we may not achieve relief on some or all of the issues involved and, as a result, could be subject to higher liquidated damages amounts. Additionally, we have asserted claims, or intend to assert claims, against certain customers that, if settled, could result in a release of such claims in exchange for release of certain liquidated damages currently recorded in our financial statements. We recognize claims for recovery of incurred cost when it is probable that the claim will result in additional contract revenue and when the amount of the claim can be reliably estimated. These requirements are satisfied when the contract or other evidence provides a legal basis for the claim, additional costs were caused by circumstances that were unforeseen at the contract date and not the result of deficiencies in our performance, claim-related costs are identifiable and considered reasonable in view of the work performed, evidence supporting the claim is objective and verifiable and collection is probable. These assessments require judgments concerning matters such as litigation developments and outcomes, the anticipated outcome of negotiations, the number of future claims and the cost of both pending and future claims.

Litigation and Claims

In the ordinary course of business, we are involved in various pending or threatened legal actions. While management is unable to predict the ultimate outcome of these actions, it believes that any ultimate liability arising from any of these actions will not have a material adverse effect on our financial position, results of operations or cash flows. However, because of the inherent uncertainty of litigation and arbitration proceedings, we cannot provide assurance that the resolution of any particular claim or proceeding to which we are a party will not have a material adverse effect on our financial position, results of operations or cash flows.

Contemporaneously with filing the Form 8-K on April 26, 2016, we self-reported the errors and possible irregularities at Belleli EPC to the SEC. Since then, we have been cooperating with the SEC in its investigation of this matter, includingwhich has included responding to a subpoena for documents related to the restatement and of our compliance with the FCPA,U.S. Foreign Corrupt Practices Act (“FCPA”), which arewere also being provided to the Department of Justice at its request. The SEC staff has notified us that they have concluded their investigation concerning our compliance with the FCPA and that they do not intend to recommend an enforcement action concerning our compliance with the FCPA. The DOJ has similarly informed us that it does not intend to proceed with any further investigation or enforcement. The SEC’s investigation related requests into the circumstances giving rise to the restatement is continuing, and we are presently unable to predict the duration, scope or results or whether the SEC subpoena pertain to our policies and procedures, information about our third-party sales agents, and documents related to historical internal investigations completed prior to November 2015.will commence any legal action.

Indemnifications

In conjunction with, and effective as of the completion of, the Spin-off, we entered into the separation and distribution agreement with Archrock, which governs, among other things, the treatment between Archrock and us ofrelating to certain aspects relating toof indemnification, insurance, confidentiality and cooperation. Generally, the separation and distribution agreement provides for cross-indemnities principally designed to place financial responsibility for the obligations and liabilities of our business with us and financial responsibility for the obligations and liabilities of Archrock’s business with Archrock. Pursuant to the agreement, we and Archrock will generally release the other party from all claims arising prior to the Spin-off that relate to the other party’s business.business, subject to certain exceptions. Additionally, in conjunction with, and effective as of the completion of, the Spin-off, we entered into the tax matters agreement with Archrock. Under the tax matters agreement and subject to certain exceptions, we are generally liable for, and indemnify Archrock against, taxes attributable to our business, and Archrock is generally liable for, and indemnify us against, all taxes attributable to its business. We are generally liable for, and indemnify Archrock against, 50% of certain taxes that are not clearly attributable to our business or Archrock’s business. Any payment made by us to Archrock, or by Archrock to us, is treated by all parties for tax purposes as a nontaxable distribution or capital contribution, respectively, made immediately prior to the Spin-off.

We define gross margin as total revenue less cost of sales (excluding depreciation and amortization expense). Gross margin is included as a supplemental disclosure because it is a primary measure used by our management to evaluate the results of revenue and cost of sales (excluding depreciation and amortization expense), which are key components of our operations. As an indicator of our operating performance, gross margin should not be considered an alternative to, or more meaningful than, net income (loss) as determined in accordance with GAAP. Our gross margin may not be comparable to a similarly titled measure of another company because other entities may not calculate gross margin in the same manner.

(2)For the periods prior to November 3, 2015, the average number of common shares outstanding used to calculate basic and diluted net income (loss) per common share was based on 34,286,267 shares of our common stock that were distributed by Archrock in the Spin-off on November 3, 2015.

Additional Notes:
(3)
In the fourth quarter of 2017, we substantially exited our Belleli EPC business and, in accordance with GAAP, it is reflected as discontinued operations in our financial statements for all periods presented (see Note 3).
In conjunction with the planned disposition of Belleli CPE, we recorded impairments of long-lived assets and current assets that totaled $61.6 million and $7.1 million during the first quarter and second quarter of 2015, we recorded $18.7 million of net proceeds from2016, respectively. We completed the sale of previously nationalized VenezuelanBelleli CPE in August 2016 for cash proceeds of $5.5 million. Belleli CPE is reflected as discontinued operations in our financial statements for all periods presented (see Note 3).
Due to significant negative evidence of cumulative losses in the U.S., we are no longer able to support that it is more-likely-than-not that we will have sufficient taxable income of the appropriate character in the future that will allow us to realize our U.S. deferred tax assets. As a result, we recorded a full valuation allowance against our U.S. deferred tax assets to PDVSA Gasresulting in additional charges of $88.0 million, $13.6 million and $18.2 million during the second quarter, third quarter and fourth quarter of 2016, respectively (see Note 4), $5.016).
During the second quarter, third quarter and fourth quarter of 2016, we incurred costs of $7.9 million, $12.3 million and $9.9 million, respectively, associated with the restatement of our financial statements and related SEC investigation, of which $11.2 million of equitycash was recovered from Archrock in incomethe fourth quarter of non-consolidated affiliates2016 pursuant to the separation and distribution agreement. During the first quarter, second quarter, third quarter and fourth quarter of 2017, we incurred costs of $2.2 million, $1.6 million, $2.0 million and $0.4 million, respectively, associated with an ongoing SEC investigation and remediation activities related to the restatement, of which $2.8 million was recovered from Archrock in the salesecond quarter of our Venezuelan joint ventures’ assets2017 (see Note 9) and $4.6 million of long-lived asset impairments (see Note 13)14).

24. Subsequent Events

In January 2016, we received an additional installment payment, including an annual charge, of $5.2 million from PDVSA Gas relating to the 2012 sale of our Venezuelan joint ventures’ previously nationalized assets. As we have not recognized amounts payable to us by PDVSA Gas relating to the 2012 sale of our Venezuelan joint ventures’ previously nationalized assets as a receivable but rather as equity in income of non-consolidated affiliates in the periods such payments are received, the installment payment received in January 2016 will be recognized as equity in income of non-consolidated affiliates in the first quarter of 2016. Pursuant to the separation and distribution agreement, a notional amount corresponding to the cash we received from the PDVSA Gas installment payment was transferred to Archrock in January 2016. The transfer of cash will be recognized as a reduction to stockholders’ equity in the first quarter of 2016.
