3

The Company's strategy is to be the industry's most cost-efficient producer in each of its product lines while continuing to develop innovative new products and provide first class service for its customers.  Management believes that the Company is the technological innovator in the markets in which it operates and is well positioned to capitalize on the need to rebuild and enhance roadway and utility infrastructure as well as in other areas in which it offers products and services, both in the United States and abroad.

Segment Reporting

The Company's business units have their own management teams and offer different products and services.  The Company's business units are aggregated into three reportable business segments based upon the nature of the product or services produced, the type of customer for the products, the similarity of economic characteristics, the manner in which management reviews results and the nature of the production process, among other considerations.  The Company's reportable business segments are (i) Infrastructure Group, (ii) Aggregate and Mining Group and (iii) Energy Group.  The remaining business units not included in one of the reportable segments provide support and corporate oversight for all the Company's business units and include Astec Industries, Inc., the parent company, and Astec Insurance Company, a captive insurance company.  We refer to these two companies as the "Corporate" category throughout this document.  The Company records U.S. federal income tax expenses for all business segments on the parent company's books; therefore, these taxes are included in the Corporate category for segment reporting.

Financial information in connection with the Company's financial reporting for segments of a business and for geographic areas under FASB Accounting Standards Codification 280 is included in Note 17, Operations by Industry Segment and Geographic Area, in "Notes to Consolidated Financial Statements" presented in Appendix A of this report.

Infrastructure Group

The Infrastructure Group segment is made up of five business units.  These business units include Astec, Inc. ("Astec"), Roadtec, Inc. ("Roadtec"), Carlson Paving Products, Inc. ("Carlson"), Astec Mobile Machinery GmbH ("AMM") and Astec Australia Pty Ltd ("Astec Australia").  Three of the business units (Astec, Roadtec and Carlson) design, engineer, manufacture and market a complete line of asphalt and wood pellet plants and their related components, asphalt pavers, screeds, milling machines, material transfer vehicles, stabilizers and related ancillary equipment.  The other two business units (AMM and Astec Australia) primarily sell, service and install products produced by the manufacturing subsidiaries of the Company with a majority of their sales to customers in the infrastructure industry.

Products

Astec designs, engineers, manufactures and markets a complete line of asphalt and wood pellet plants and related components primarily for the asphalt production and paving and wood pellet industries.  Certain component equipment supplied by Astec for asphalt and wood pellet plants is manufactured by other Company subsidiaries such as heating and storage equipment (manufactured by the Company's Energy Group) and material handling equipment (manufactured by the Company's Aggregate and Mining Group).  A typical asphalt mixing plant consists of heating and storage equipment for liquid asphalt; cold feed bins for blending aggregates; a counter-flow continuous type unit (Astec Double Barrel) for drying, heating and mixing; a baghouse composed of air filters and other pollution control devices; hot storage bins or silos for temporary storage of hot-mix asphalt; and a control house. Astec introduced the concept of high plant portability for asphalt plants in 1979. Its current generation of portable asphalt plants is marketed as the Six Pack and consists of six or more portable components designed to be easily relocated from one construction site to another, thereby reducing relocation expenses. High plant portability represents an industry innovation developed and successfully marketed by Astec.

Astec developed the patented warm system, which allows the asphalt mix to be prepared and placed at lower temperatures than conventional systems and operates with a substantial reduction in emissions during paving and load-out. Previous technologies for warm mix production rely on expensive additives, procedures and/or special asphalt cement delivery systems that significantly increase the cost per ton of mix. The Company's Astec multi-nozzle device eliminates the need for the expensive additives by mixing a small amount of water and asphalt cement together to create microscopic bubbles that reduce the viscosity of the asphalt mix coating on the rock, thereby allowing the mix to be handled and worked at lower temperatures.

Astec is focused on producing equipment with the most advanced mix recycling technology in the industry.  More tons of asphalt are available for recycling than is currently being utilized due to restrictions in the amount of recycle allowed by various governmental agencies.  Astec's recycle technology is continuously being enhanced and is providing the science to alleviate the concerns driving such restrictions and thereby improve recycling percentages in the asphalt industry.  Astec's latest system improvement in this area, the RAP Pre-Dryer System, is expected to be introduced to customers in 2018.

The components in Astec's asphalt mixing plants are fully automated and use both microprocessor-based and programmable logic control systems for efficient operation. The plants are manufactured to meet or exceed federal and state clean air standards. Astec also builds batch type asphalt plants and has developed specialized asphalt recycling equipment for use with its hot-mix asphalt plants.

Astec's wood pellet plants have been in commercial production since 2013. Astec's modular design for its wood pellet plants includes replicated parallel production lines (for instance, a 60 ton-per-hour ("TPH") plant consists of three 20 TPH lines) resulting in very few points in the process where any individual equipment failure can shut the entire plant down.  In most other pellet plant designs, one small equipment failure, such as a dryer outage, would result in a total plant shutdown. If a dryer outage were to occur in a 60 TPH Astec plant, the plant could continue to operate at 40 TPH. In fact, there are very few reasons why the plant would ever be completely shut down. Even major maintenance cycles may be performed line-by-line while the plant continues to operate on the other lines.

Roadtec manufactures asphalt pavers, material transfer vehicles, milling machines, soil stabilizing-reclaiming machinery and other equipment used in road building and resurfacing.  Roadtec pavers have been designed to minimize maintenance costs while exceeding road surface smoothness requirements.  The equipment offered by Roadtec can be used in tandem with each other or separately with equipment already owned by the customer.

5

Roadtec's Shuttle Buggy is a mobile, self-propelled material transfer vehicle which allows continuous paving by separating truck unloading from the paving process while remixing the asphalt.  A typical asphalt paver must stop paving to permit truck unloading of asphalt mix.  By permitting continuous paving, the Shuttle Buggy allows the asphalt paver to produce a smoother road surface while reducing the time required to pave the road surface and reducing the number of haul trucks required.  As a result of the pavement smoothness achieved with this machine, certain states now require the use of the Shuttle Buggy.  Studies using infrared technology have revealed problems caused by differential cooling of the hot-mix during hauling.  The Shuttle Buggy remixes the material to a uniform temperature and gradation, thus eliminating these problems.  Roadtec introduced its newest version of its highly successful Shuttle Buggy to the market at ConExpo 2017, which includes the new Guardian System that is designed to anticipate maintenance needs resulting in more uptime reliability while also providing production and performance data as well as real time location information to the owner.  Roadtec's Spray Paver model, which is recommended for use with the Shuttle Buggy, is also designed to carry and spray tack coat directly in front of the hot mix asphalt in a single process, thus eliminating the need for a separate tack truck.

Roadtec manufactures milling machines designed to remove old asphalt from the road surface before new asphalt mix is applied.  Roadtec's line of milling machines, which are designed for larger jobs, are manufactured with a simplified control system, wide conveyors, direct drives and a wide range of horsepower and cutting capabilities to provide versatility in product application.  In addition to its half-lane and larger highway class milling machines, Roadtec also manufactures a smaller, utility class machine for two-to-four foot cutting widths and a utility class cold planer model mounted on steel wheels.

Roadtec currently produces soil stabilizers in configurations of 275HP, 440HP, 625HP and 755HP.  These machines double as asphalt reclaiming machines for road rehabilitations, in addition to their primary purpose of stabilizing soil sub-grades with additives to provide an improved base on which to pave.

Carlson manufactures its patented screeds which attach to asphalt paving machines and place asphalt on the roadbed at a desired thickness and width while smoothing and compacting the surface.  Carlson screeds can be configured to fit many types of asphalt paving machines, including machines manufactured by both the Company and its competitors. The Carlson screed uses a hydraulic powered generator to electrify elements that heat a screed plate so asphalt will not stick to it while paving.  A generator is also available to power tools or lights for night paving.  Carlson offers options to its screeds which allow extended paving widths and the addition of a curb on the road edge.  Carlson also offers commercial class eight-foot pavers designed for parking lots, residential driveways and secondary road applications.

Astec Mobile Machinery functions primarily as a distributor of Roadtec products in the European market.  Additionally, it designed and manufactures a small road widener attachment to meet the unique needs of the European market.

Astec Australia markets relocatable and portable asphalt plants and components produced by Astec, Heatec and CEI, asphalt paving equipment and components produced by Roadtec and Carlson, and aggregate equipment produced by the Company's Aggregate & Mining Group.  A majority of its sales are to customers in the infrastructure industry.  In addition to selling equipment, Astec Australia provides complete support for its customers' equipment with service, training and spare parts.  Astec Australia also provides turnkey installation solutions for large asphalt plants, aggregate and mining plants and bitumen tank farms.

Marketing

The Company markets its hot-mix asphalt products domestically under the Astec and Astec Dillman trademarks and internationally under the Astec trademarks.  Asphalt plants and related equipment are sold directly to asphalt producers or domestic and foreign government agencies through Astec's domestic and international sales departments and through a Company-owned dealership (Astec Australia), although independent agents are also used to market asphalt plants and their components in certain international markets.  The Company markets wood pellet plants to individual independent producers who supply wood pellets to the utility and home-use industries.

The Company markets its asphalt paving equipment both domestically and internationally to highway and heavy equipment contractors, utility contractors and foreign and domestic governmental agencies both directly and through dealers (including Astec Australia in the Australian and New Zealand markets and AMM in the European market).  Mobile construction equipment and factory authorized machine rebuild services are marketed both directly and through dealers.

This segment's products are marketed by 78 direct sales staff, 47 domestic independent distributors and 113 international independent distributors, including Astec's subsidiaries in Australia and Germany.

Raw Materials

Raw materials used in the manufacture of products in the Infrastructure Group include carbon steel, pipe and various types of alloy steel, which are normally purchased from distributors and other sources.  Raw materials for manufacturing are normally readily available.  Most steel is delivered on a "just-in-time" arrangement from the supplier to reduce inventory requirements at the manufacturing facilities, but steel is occasionally inventoried after purchase.  Other components used in the manufacturing processes include engines, gearboxes, power transmissions and electronic systems.

Competition

This industry segment faces strong competition in price, service and product performance and competes with both large publicly-held companies and various smaller manufacturers. Domestic hot-mix asphalt plant competitors include Gencor Industries, Inc., ADM and Almix.  In the international market, the hot-mix asphalt plant competitors include Ammann, Fayat/Marini, Benninghoven/Deere and local manufacturers.  Paving equipment and screed competitors include Weiler, Caterpillar Paving Products, Volvo Construction Equipment, Vogele America, Dynapac, Bomag Fayat Group and Lee Boy.  The segment's milling machine equipment competitors include Wirtgen, CMI, Caterpillar, Bomag, Dynapac and Volvo.  The Company believes that it is the only company offering a single source for a complete pellet plant, as known competitors only sell individual plant components thereby requiring the customer to purchase the remaining plant components from other sources.

Employees

At December 31, 2017, the Infrastructure Group segment employed 1,712 individuals, of which 1,236 were engaged in manufacturing, 187 in engineering and 289 in selling, general and administrative functions. None of the employees of the Infrastructure Group are covered by collective bargaining agreements.

7

Backlog

The backlog for the Infrastructure Group at December 31, 2017 and 2016 was approximately $239,495 and $232,224, respectively. Approximately $60,000 of the 2017 and 2016 backlogs relate to the Company's first three-line pellet plant order from a single customer.  Substantially all of this order was manufactured and delivered to the customer prior to December 31, 2015, with continuing enhancements being developed and installed during 2016 and 2017.  As the Company is financing this sale, revenue recognition on the plant sale will not occur until customer payments are received, which is expected to begin in late 2018.  Management expects all the current backlog to be filled in 2018.

Aggregate and Mining Group

The Company's Aggregate and Mining Group is comprised of eight business units which are focused on designing and manufacturing heavy processing equipment, as well as servicing and supplying parts for the aggregate, metallic mining, recycling, ports and bulk handling markets.  These business units are Telsmith, Inc. ("Telsmith"), Kolberg-Pioneer, Inc. ("KPI"), Astec Mobile Screens, Inc. ("AMS"), Johnson Crushers International, Inc. ("JCI"), Breaker Technology Ltd/Breaker Technology, Inc. ("BTI"), Osborn Engineered Products, SA (Pty) Ltd ("Osborn"), Astec do Brasil Fabricacao de Equipamentos Ltda. ("Astec Brazil") and Telestack Limited ("Telestack").

Products

Telsmith designs, engineers, manufactures and supports equipment servicing the construction, aggregate, metallic mining and recycling markets. Telsmith's core products are crushers, vibrating equipment, modular relocatable stationary plants, mobile portable plants and larger track-mounted systems.  Telsmith also provides consulting and engineering services to provide complete "turnkey" processing systems. These systems often include electrical control centers and plan automation products engineered and produced by Telsmith.

Telsmith maintains an ISO 9001:2015 certification, an internationally recognized standard of quality assurance. In addition, Telsmith has achieved CE designation (a standard for quality assurance and safety) on its crushing and vibration equipment products marketed into European Union countries.

Telsmith is a world leader in the development of hydraulic relief jaw crushers having patented its first model in 2002. Hydraulic relief jaw crushers are a significant improvement in safety, adjustment and clearing of material in jaw crushers.

KPI, JCI and AMS design, engineer, manufacture and support a complete line of stationary and portable aggregate processing equipment for the aggregate metallic and nonmetallic, bulk handling, sand and gravel, mining, quarrying, concrete and asphalt recycling and industrial markets. This equipment is marketed through an extensive network of KPI/JCI/AMS dealers.

KPI/JCI/AMS products include a complete line of primary, secondary, tertiary and quaternary crushers, including jaw, horizontal shaft impactor, vertical shaft impactor and roll rock crushers as well as industry related washing and conveying equipment, mobile screening plants, portable and stationary screen structures and vibrating and high frequency screens. These rock crushers are used by mining, quarrying and sand and gravel producers to crush oversized aggregate to salable size, in addition to their use for recycled concrete and asphalt. This equipment can be purchased as individual components, as portable plants for flexibility or as completely engineered systems for both portable, stationary and RAP applications. They also offer the highly-portable Fast Pack System, featuring quick setup and teardown, thereby maximizing production time and minimizing downtime. KPI/JCI/AMS also offers portable fully self-contained and self-propelled Fast Trax track-mounted jaw, cone, VSI and horizontal shaft crushers, which are ideal for either recycle or hard rock applications, allowing the producer to move the equipment to the material.  The KPI/JCI/AMS expanded GT line of track-mounted crushing and screening plants focuses more specifically on the need for rental and global markets.

KPI/JCI/AMS portable plants combine various combinations of crushing, screening and conveying equipment mounted on tow away chassis and track chassis configurations.  Due to high transportation costs of construction materials, many producers use portable equipment to process materials they need in close proximity to their job sites.  Portable plants allow aggregate producers the ability to quickly and efficiently move equipment from one location to another as their jobs necessitate.   The portable track plants are fully self-contained and allow operators to be producing materials within minutes of unloading equipment off of their transport trucks.  The introduction of track-mounted crushing and screening plants has enabled contractors to perform jobs that in the past were not economically feasible and also allows our dealers to compete in the large track-mounted rental market. 

KPI/JCI/AMS sand classifying and washing equipment is designed to clean, separate and re-blend material from sand deposits to meet the size specifications for critical applications. Products offered include fine and coarse material washers, log washers, blade mills, sand classifying tanks, cyclones, dewatering screens, density classifiers, sieve blend screens and attrition cells.

13

Corporate (Other Business Units)

This category consists of the two business units that do not meet the requirements of separate disclosure as an operating segment or inclusion in one of the other reporting segments and includes Astec Industries, Inc., the parent company, and Astec Insurance Company, a captive insurance company.  These two companies provide support and corporate oversight for all the other business units.  The Company records U.S. federal income tax expenses for all business segments on the parent company's books; therefore, these taxes are included in the Corporate category for segment reporting.

Employees

At December 31, 2017, the Corporate category employed 46 individuals, all of which were engaged in executive management, corporate finance and administrative functions.

Common to All Operating Segments

The following information applies to all operating segments of the Company.

Raw Materials

Steel is a major component in the Company's equipment. Steel followed typical seasonal patterns during 2017, peaking in April and reaching lows in November. Prices began to rise in early 2018 and are expected to continue to rise with seasonal demand and an improving economy in the first and second quarters of 2018. The Company expects normal seasonal price movement during 2018 with steel prices higher on average than in 2017. The Company continues to utilize forward-looking contracts (with no minimum or specified quantity guarantees) coupled with advanced steel purchases to minimize the impact of any price increases.  The Company will review the trends in steel prices entering into the second half of 2018 and establish future contract pricing accordingly.

Government Regulations

The Company is subject to various laws and governmental regulations concerning environmental matters and employee safety and health in the United States and other countries. The Environmental Protection Agency, the Occupational Safety & Health Administration, other federal agencies and certain state agencies have the authority to promulgate regulations that have an effect on the Company's operations.  Many of these federal and state agencies may seek fines and penalties for violations of these laws and regulations.  The Company has been able to operate under these laws and regulations without any material adverse effect on its business.

None of the Company's operating segments operate within highly regulated industries.  However, air pollution control equipment manufactured by the Company, principally for hot-mix asphalt plants, must comply with certain performance standards promulgated by the federal Environmental Protection Agency under the Clean Air Act applicable to "new sources" or new plants.  Management believes the Company's products meet all material requirements of such regulations and applicable state pollution standards and environmental protection laws.

14

In addition, due to the size and weight of certain equipment the Company manufactures, the Company and its customers may encounter various state regulations on maximum weights transportable on highways.  Also, some states have regulations governing the operation of asphalt mixing plants, and most states have regulations relating to the accuracy of weights and measures, which affect some of the control systems manufactured by the Company.

Compliance with these government regulations has no material effect on the Company's capital expenditures, earnings or competitive position within the market.

Employees

At December 31, 2017, the Company and its subsidiaries employed 4,437 individuals, of which 3,123 were engaged in manufacturing, 463 in engineering, including support staff, and 851 in selling, administrative and management functions.

Other than the Telsmith and Osborn labor agreements described under the "Employee" subsection of the Aggregate and Mining Group above and the GEFCO and Power Flame labor agreements described under the "Employee" subsection of the Energy Group above, there are no collective bargaining agreements applicable to employees of the Company or its subsidiaries.  The Company considers its employee relations to be good.

Manufacturing

The Company manufactures many of the component parts and related equipment for its products, while several large components of its products are purchased "ready-for-use".  Such items include engines, axles, tires and hydraulics.  In many cases, the Company designs, engineers and manufactures custom component parts and equipment to meet the particular needs of individual customers.  Manufacturing operations during 2017 took place at 21 separate locations.  The Company's manufacturing operations consist primarily of fabricating steel components and the assembly and testing of its products to ensure that the Company achieves quality control standards.

Seminars and Technical Bulletins

The Company periodically conducts technical and service seminars, which are primarily for dealer representatives, contractors, owners, employees and other users of equipment manufactured by the Company.  In 2017, approximately 660 representatives of contractors and owners of hot-mix asphalt plants attended seminars held by the Company in Chattanooga, Tennessee.  These seminars, which are led by Company management and employees, along with select outside speakers and discussion leaders, cover a range of subjects, including, but not limited to, technological innovations in the hot-mix asphalt, aggregate processing, paving, milling and recycling markets.

15

During 2017, 10 service training seminars were held at the Roadtec facility for approximately 520 customer representatives, and 12 remote seminars were conducted at other locations for approximately 200 additional customer personnel.  CEI conducted four service schools during 2017, with approximately 76 customer representatives attending. Heatec conducted two service schools in 2017 with approximately 50 customer representatives attending and also conducted four remote seminars at other locations for approximately 95 additional customer personnel. Telsmith conducted three technical seminars for approximately 85 customer and dealer representatives during 2017.  KPI, JCI and AMS jointly conduct National Dealers Conference, an annual dealer event. The event offers the entire dealer network a preview of future products, marketing and promotional programs to help dealers operate successful businesses. In addition to this event, the companies also provide factory customer and dealer training and on-site local, regional and national sales training programs throughout the year. Peterson conducted four regional service schools during 2017, with approximately 100 customer representatives attending, and two customer focus group meetings for 40 of the company's elite users where attendees shared best-of-the-best operational processes and participated in future product development.

In addition to seminars, the Company publishes a number of technical bulletins and information bulletins detailing various technological and business issues relating to the industries in which it operates.

Patents and Trademarks

The Company seeks to obtain patents to protect the novel features of its products and processes.  The Company's subsidiaries hold 88 United States patents and 103 foreign patents.  The Company's subsidiaries have 65 United States and 76 foreign patent applications pending.  

The Company and its subsidiaries have 84 trademarks registered in the United States, including logos for Astec, Astec Dillman, Carlson Paving, CEI, GEFCO, Heatec, JCI, Peterson Pacific, Power Flame, Roadtec, and Telsmith, and the names ASTEC, CARLSON, HEATEC, JCI, KOLBERG, PETERSON, ROADTEC and TELSMITH, as well as a number of other product names.  The Company also has 114 trademarks registered in foreign jurisdictions, including Australia, Argentina, Brazil, Canada, China, France, Great Britain, Germany, India, Italy, Kazakhstan, Mexico, Paraguay, New Zealand, Peru, Russia, South Africa, South Korea, Thailand, Uruguay, Vietnam and the European Union.  The Company and its subsidiaries have six United States and six foreign trademark registration applications pending.

Engineering and Product Development

The Company dedicates substantial resources to engineering and product development. At December 31, 2017, the Company and its subsidiaries had 463 full-time individuals employed in engineering and design capacities.

Seasonality and Backlog

Revenues for recent years, adjusted for acquisitions, have been strongest during the first half of the year, with the second half of the year consistently being weaker. We expect future operations in the near term to be typical of this historical trend.

As of December 31, 2017 and 2016, the Company had a backlog for delivery of products at certain dates in the future of approximately $411,469 and $361,831, respectively.  The Company's contracts reflected in the backlog generally are not, by their terms, subject to termination.  Management believes the Company is in substantial compliance with all manufacturing and delivery timetables.

16

Competition

Each business segment operates in domestic markets that are highly competitive with respect to price, service and product quality.  While specific competitors are named within each business segment discussion above, imports do not generally constitute significant competition for the Company in the United States, except for milling machines and track-mounted crushers.  In international sales, however, the Company often competes with foreign manufacturers that may have a local presence in the market the Company is attempting to penetrate.

In addition, asphalt and concrete are generally considered competitive products as a surface choice for new roads and highways.  A portion of the interstate highway system is paved in concrete, but over 90% of all surfaced roads in the United States are paved with asphalt.  Although concrete is used for some new road surfaces, asphalt is used for most resurfacing.

Item 1A. Risk Factors

Downturns in the general economy or the commercial and residential construction industries may adversely affect our revenues and operating results.

General economic downturns, including downturns in the commercial and residential construction industries, could result in a material decrease in our revenues and operating results.  Demand for many of our products, especially in the commercial construction industry, is cyclical.  Sales of our products are sensitive to the states of the U.S., foreign and regional economies in general, and in particular, changes in commercial construction spending and government infrastructure spending.  In addition, many of our costs are fixed and cannot be quickly reduced in response to decreased demand.  The following factors could cause a downturn in the commercial and residential construction industries:

· a decrease in the availability of funds for construction;

· declining economy domestically and internationally;

· labor disputes in the construction industry causing work stoppages;

· rising gas and oil prices;

· rising steel prices and steel surcharges;

· rising interest rates;

· energy or building materials shortages;

· inclement weather; and

· availability of credit for customers.

17

Downturns in the general economy and restrictions in the credit markets may negatively impact our earnings, cash flows and/or financial position and access to financing sources by the Company and our customers. 

Worldwide economic conditions and the international credit markets significantly deteriorated in recent years and may remain depressed for the foreseeable future. Continued deterioration of economic conditions and credit markets could adversely impact our earnings as sales of our products are sensitive to general declines in U.S. and foreign economies and the ability of our customers to obtain credit.  In addition, we rely on the capital markets and the banking markets to meet our financial commitments and short-term liquidity needs if internal funds are not available from our operations. Further disruptions in the capital and credit markets, or deterioration of our creditors' financial condition, could adversely affect the Company's ability to draw on its revolving credit facility.  The Company's current credit facility expires in April 2022, and deterioration in the credit markets could make it more difficult or expensive for us to replace our current credit facility, enter into a new credit facility or obtain additional financing.

A decrease or delay in government funding of highway construction and maintenance may cause our revenues and profits to decrease.

Many of our customers depend on government funding of highway construction and maintenance and other infrastructure projects.  Any decrease or delay in government funding of highway construction and maintenance and other infrastructure projects could cause our net sales and profits to decrease.  Historically, federal government funding of infrastructure projects has typically been accomplished through bills that establish funding over a multi-year period, such as the Safe, Accountable, Flexible and Efficient Transportation Equity Act - A Legacy for Users ("SAFETEA-LU"), which provided $286.5 billion to fund federal transit projects from 2004 to 2009.  SAFETEA-LU funding expired on September 30, 2009, and federal transportation funding operated on a number of shorter term appropriations until December 4, 2015 when the Fixing America's Surface Transportation Act ("FAST Act") was enacted.  Among other expenditures, the FAST Act approved funding for highways of approximately $205 billion and funding for transit projects of approximately $48 billion for the five-year period ending September 30, 2020.

Given the inherent uncertainty in the political process, the level of government funding for federal highway projects will similarly continue to be uncertain.  Governmental funding that is committed or earmarked for federal highway projects is always subject to repeal or reduction.  Although continued funding under the FAST Act is expected, it may be at lower levels than originally approved.  In addition, Congress could pass legislation in future sessions that would allow for the diversion of previously appropriated highway funds for other national purposes, or it could restrict funding of infrastructure projects unless states comply with certain federal policies.

The cyclical nature of our industry and the customization of the equipment we sell may cause adverse fluctuations to our revenues and operating results.

We sell equipment primarily to contractors whose demand for equipment depends greatly upon the volume of road or utility construction projects underway or to be scheduled by both government and private entities.  The volume and frequency of road and utility construction projects are cyclical; therefore, demand for many of our products is cyclical.  The equipment we sell is durable and typically lasts for several years, which also contributes to the cyclical nature of the demand for our products.  As a result, we may experience cyclical fluctuations to our revenues and operating results. Any difficulty in managing the Company's manufacturing workflow during downturns in demand could adversely affect our financial results.

18

A significant change in the price or availability of oil could reduce demand for our products.  Significant increases in the purchase price of certain raw materials used to manufacture our equipment could have a negative impact on the cost of production and related gross margins.

A significant portion of our revenues relates to the sale of equipment involved in the production, handling, recycling or installation of asphalt mix.  Liquid asphalt is a byproduct of the refining of oil, and asphalt prices correlate with the price and availability of oil.  An increase in the price of oil or a decrease in the availability of oil would increase the cost of producing asphalt, which would likely decrease demand for asphalt, resulting in decreased demand for many of our products.  This would likely cause our revenues and profits to decrease.  Rising gasoline, diesel fuel and liquid asphalt prices will also adversely impact the operating and raw material costs of our contractor and aggregate producer customers, and if such customers do not properly adjust their pricing, they could experience reduced profits resulting in possible delays in purchasing capital equipment.

Contrary to the impact of increasing oil prices on many of the Company's products impacted by changes in the cost of asphalt mix as discussed above, the products manufactured by the Company's Energy Group, which are used in drilling for oil and natural gas, in heaters for refineries and oil sands, and in double fluid pump trailers for fracking and oil and gas extraction, would be negatively impacted by lower oil and natural gas prices, to the extent that such lower prices lead to decreased development in the oil and natural gas production industries.

Steel is a major component in the Company's equipment. Steel prices fluctuate routinely. Our reliance on third-party suppliers for steel and other raw materials exposes us to volatility in the prices and availability of these materials. Price increases or a decrease in the availability of these raw materials could increase our operating costs and adversely affect our financial results. 

Acquisitions that we have made in the past and future acquisitions involve risks that could adversely affect our future financial results.

We have completed several acquisitions in the past, including the acquisition of RexCon in October 2017 and Power Flame in August 2016.  We may acquire additional businesses in the future.  We may be unable to achieve the benefits expected to be realized from our acquisitions.  In addition, we may incur additional costs and our management's attention may be diverted because of unforeseen expenses, difficulties, complications, delays and other risks inherent in acquiring businesses, including the following:

· we may have difficulty integrating the financial and administrative functions of acquired businesses;

· acquisitions may divert management's attention from our existing operations;

· fluctuations in exchange rates and a weakening of the dollar may impact the competitiveness of acquired businesses;

· we may have difficulty in competing successfully for available acquisition candidates, completing future acquisitions or accurately estimating the financial effect of any businesses we acquire;

· we may have delays in realizing the benefits of our strategies for an acquired business;

· we may not be able to retain key employees necessary to continue the operations of the acquired business;

· acquisition costs may deplete significant cash amounts or may decrease our operating income;

· we may choose to acquire a company that is less profitable or has lower profit margins than our company;

· future acquired companies may have unknown liabilities that could require us to spend significant amounts of additional capital; and

· we may incur domestic or international economic declines that impact our acquired companies.

19

Competition could reduce revenue from our products and services and cause us to lose market share.

We currently face strong competition in product performance, price and service.  Some of our domestic and international competitors have greater financial, product development and marketing resources than we have.  If competition in our industry intensifies or if our current competitors enhance their products or lower their prices for competing products, we may lose sales or be required to lower the prices we charge for our products.  This may reduce revenue from our products and services, lower our gross margins or cause us to lose market share.

Our success depends on key members of our management and other employees.

Certain members of our senior management team are of significant importance to our business and operations.  The loss of their services may adversely affect our business.  In addition, our ability to attract and retain qualified engineers, skilled manufacturing personnel and other professionals, either through direct hiring or acquisition of other businesses employing such professionals, will also be an important factor in determining our future success.

Difficulties in managing and expanding in international markets could divert management's attention from our existing operations.

In 2017, international sales represented approximately 21.3% of our total sales as compared to 18.0% in 2016.  We plan to continue our significant sales and production efforts in international markets and recently filled a new company position of Group Managing Director-International to assist with our efforts.  In connection with any increase in international sales efforts, we will need to hire, train and retain qualified personnel in countries where language, cultural or regulatory barriers may exist.  Any difficulties in expanding our international sales may divert management's attention from our existing operations.  In addition, international revenues are subject to the following risks:

· fluctuating currency exchange rates, which can reduce the profitability of foreign sales;

· the burden of complying with a wide variety of foreign laws and regulations;

· dependence on foreign sales agents;

· political and economic instability of governments;

· the imposition of protective legislation such as import or export barriers; and

· fluctuating strengths or weakness of the dollar, which can impact net sales or the cost of purchased products.

We may be unsuccessful in complying with the financial ratio covenants or other provisions of our credit agreement.

As of December 31, 2017, we were in compliance with the financial covenants contained in our credit agreement with Wells Fargo Bank, N.A.  However, in the future we may be unable to comply with the financial covenants in our credit facility or to obtain waivers with respect to such financial covenants.  If such violations occur, the Company's creditors could elect to pursue their contractual remedies under the credit facility, including requiring immediate repayment in full of all amounts then outstanding.  As of December 31, 2017, the Company had no outstanding borrowings under the Wells Fargo credit agreement but did have $9,757,000 of letters of credit outstanding under the credit agreement.  Additional amounts may be borrowed in the future.  The Company's Osborn, Astec Brazil, Telestack and Astec Australia subsidiaries have entered into their own independent loan agreements.

20

Our quarterly operating results are likely to fluctuate, which may decrease our stock price.

Our quarterly revenues, expenses and operating results have varied significantly in the past and are likely to vary significantly from quarter to quarter in the future.  As a result, our operating results in some quarters may fall below the expectations of securities analysts and investors, which could result in a decrease in the market price of our common stock.  The reasons our quarterly results may fluctuate include:

· general competitive and economic conditions, domestically and internationally;

· delays in, or uneven timing in, the delivery of customer orders;

· the seasonal trend in our industry;

· the introduction of new products by us or our competitors;

· product supply shortages; and

· reduced demand due to adverse weather conditions.

Period-to-period comparisons of such items should not be relied on as indications of future performance.

We may face product liability claims or other liabilities due to the nature of our business.  If we are unable to obtain or maintain insurance or if our insurance does not cover liabilities, we may incur significant costs which could reduce our profitability.

We manufacture heavy machinery, which is used by our customers at excavation and construction sites, ports and inland terminals and on high-traffic roads.  Any defect in or improper operation of our equipment can result in personal injury and death, and damage to or destruction of property, any of which could cause product liability claims to be filed against us.  The amount and scope of our insurance coverage may not be adequate to cover all losses or liabilities we may incur in the event of a product liability claim.  We may not be able to maintain insurance of the types or at the levels we deem necessary or adequate or at rates we consider reasonable.  Any liabilities not covered by insurance could reduce our profitability or have an adverse effect on our financial condition.

If we are unable to protect our proprietary technology from infringement or if our technology infringes technology owned by others, then the demand for our products may decrease or we may be forced to modify our products, which could increase our costs.

We hold numerous patents covering technology and applications related to many of our products and systems as well as numerous trademarks and trade names registered with the U.S. Patent and Trademark Office and in foreign countries.  Our existing or future patents or trademarks may not adequately protect us against infringements, and pending patent or trademark applications may not result in issued patents or trademarks.  Our patents, registered trademarks and patent applications, if any, may not be upheld if challenged, and competitors may develop similar or superior methods or products outside the protection of our patents.  This could reduce demand for our products and materially decrease our revenues.  If our products are deemed to infringe upon the patents or proprietary rights of others, we could be required to modify the design of our products, change the name of our products or obtain a license for the use of some of the technologies used in our products.  We may be unable to do any of the foregoing in a timely manner, upon acceptable terms and conditions, or at all, and the failure to do so could cause us to incur additional costs or lose revenues.

If we become subject to increased governmental regulation, we may incur significant costs.

Our hot-mix asphalt plants contain air pollution control equipment and several of our other products contain engines that must comply with performance standards promulgated by the Environmental Protection Agency.  These performance standards may increase in the future.  Changes in these requirements could cause us to undertake costly measures to redesign or modify our equipment or otherwise adversely affect the manufacturing processes of our products.  Such changes could have a material adverse effect on our operating results.

In addition, we may incur material costs or liabilities in connection with other regulatory requirements applicable to our business, including, for example, state regulation of our component equipment, the accuracy of weights and measures, and the maximum weight transportable on highways and roads.

As an innovative leader in the industries in which we operate, we occasionally undertake the engineering, design, manufacturing, construction and installation of equipment systems that are new to the market.  Estimating the costs of such innovative equipment can be difficult and could result in our realization of significantly reduced or negative margins on such projects.  Additionally, if the newly designed equipment were not to function as expected, the Company could be responsible for reimbursing the customer for its financial losses, including, but not limited to, the possible refund of the purchase price.

At various times, we have experienced negative margins on certain large projects, including wood pellet plants recently produced. These large projects have included both existing and innovative equipment designs, on-site construction and promised minimum production levels.  Designing innovative equipment to function as expected is inherently difficult and significant additional design phase, field testing and redesign costs may be incurred. In addition, any number of unforeseen circumstances, can impact actual project costs.  Production delays, design changes and adverse weather conditions, etc. can also result in construction and testing delays which can cause significant cost overruns or the missing of required completion dates.  In certain circumstances, we may incur contractual penalties as a result of such delays or minimum production levels, and be liable to customers for other losses they incur in connection with such delays, including possible refund of the purchase price.  We may not be able to sufficiently predict the extent of such unforeseen cost overruns and may experience significant losses on specialized projects in the future.  Additionally, the Company typically incurs substantial research and development costs each year and has historically received significant research and development tax credits due to these expenditures.  Congress could reduce or eliminate such tax credits in future years, which could have a material adverse effect on our operating results.

Our Articles of Incorporation and Bylaws and Tennessee law may inhibit a takeover, which could delay or prevent a transaction in which shareholders might receive a premium over market price for their shares.

Our charter and bylaws and Tennessee law contain provisions that may delay, deter or inhibit a future acquisition or an attempt to obtain control of us.  This could occur even if our shareholders are offered an attractive value for their shares or if a substantial number or even a majority of our shareholders believe the takeover is in their best interest.  These provisions are intended to encourage any person interested in acquiring us or obtaining control of us to negotiate with and obtain the approval of our Board of Directors in connection with the transaction.  Provisions that could delay, deter or inhibit a future acquisition or an attempt to obtain control of us include the following:

· having a staggered Board of Directors;

· requiring a two-thirds vote of the total number of shares issued and outstanding to remove directors other than for cause;

· requiring advance notice of actions proposed by shareholders for consideration at shareholder meetings;

· limiting the right of shareholders to call a special meeting of shareholders;

· requiring that all shareholders entitled to vote on an action provide written consent in order for shareholders to act without holding a shareholders' meeting; and

· being governed by the Tennessee Control Share Acquisition Act.

Item 3. Legal Proceedings

The Company is currently a party to various claims and legal proceedings that have arisen in the ordinary course of business.  If management believes that a loss arising from such claims and legal proceedings is probable and can reasonably be estimated, the Company records the amount of the loss (excluding estimated legal costs), or the minimum estimated liability when the loss is estimated using a range and no point within the range is more probable than another.  As management becomes aware of additional information concerning such contingencies, any potential liability related to these matters is assessed and the estimates are revised, if necessary.  If management believes that a material loss arising from such claims and legal proceedings is either (i) probable but cannot be reasonably estimated or (ii) reasonably possible but not probable, the Company does not record the amount of the loss, but does make specific disclosure of such matter.  Based upon currently available information and with the advice of counsel, management believes that the ultimate outcome of its current claims and legal proceedings, individually and in the aggregate, will not have a material adverse effect on the Company's financial position, cash flows or results of operations.  However, claims and legal proceedings are subject to inherent uncertainties and rulings unfavorable to the Company could occur.  If an unfavorable ruling were to occur, there exists the possibility of a material adverse effect on the Company's financial position, cash flows or results of operations.

Item 4. Mine Safety Disclosures

Evaluation of Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to the Company's management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

The Company's management, under the supervision and with the participation of the Company's principal executive officer and principal financial officer, has evaluated the effectiveness of the Company's disclosure controls and procedures as of the end of the period covered by this report. The scope of management's assessment of the effectiveness of the Company's internal control over financial reporting as of December 31, 2017 excluded the business unit that the Company acquired on October 1, 2017 (RexCon, Inc.). The total consolidated assets with respect to the excluded business unit were $29.3 million as of December 31, 2017, and the total consolidated revenues with respect to the excluded business unit were $2.7 million for the year ended December 31, 2017.

Based upon that evaluation, the Company's principal executive officer and principal financial officer concluded that, as of the end of the period covered by this report, the Company's disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) were effective.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS

(Dollar and share amounts in thousands, except per share amounts, unless otherwise specified)

The following discussion contains forward-looking statements that involve inherent risks and uncertainties. Actual results may differ materially from those contained in these forward-looking statements. For additional information regarding forward-looking statements, see "Forward-looking Statements" on page A-21.

Overview

The Company is a leading manufacturer and seller of equipment for the road building, aggregate processing, geothermal, water, oil and gas, and wood processing industries. The Company's businesses:

· design, engineer, manufacture and market equipment used in each phase of road building, including mining, quarrying and crushing the aggregate, mobile bulk and material handling solutions, producing asphalt or concrete, recycling old asphalt or concrete and applying the asphalt;

· design, engineer, manufacture and market additional equipment and components, including equipment for geothermal drilling, oil and natural gas drilling, industrial heat transfer, wood chipping and grinding, wood pellet processing, commercial and industrial burners, combustion control systems; and

· manufacture and sell replacement parts for equipment in each of its product lines.

The Company, as we refer to it herein, consists of a total of 21 companies that are consolidated in our financial statements, which includes 17 manufacturing companies, two companies that operate as dealers for the manufacturing companies, a captive insurance company and the parent company. RexCon, Inc. was purchased by the Company on October 1, 2017 and is included in the number of companies disclosed above. The companies fall within three reportable operating segments: the Infrastructure Group, the Aggregate and Mining Group and the Energy Group.

Infrastructure Group - This segment consists of five business units, three of which design, engineer, manufacture and market a complete line of asphalt plants, asphalt pavers, wood pellet plants and related components and ancillary equipment. The two remaining companies in the Infrastructure Group primarily sell, service and install equipment produced by the manufacturing subsidiaries of the Company, with the majority of sales to the infrastructure industry.

Aggregate and Mining Group - This segment consists of eight business units that design, manufacture and market heavy equipment and parts in the aggregate, metallic mining, quarrying, recycling, ports and bulk handling industries.

Energy Group - This segment consists of six business units that design, manufacture and market heaters, gas, oil and combination gas/oil burners, combustion control systems, drilling rigs, concrete plants, wood chippers and grinders, pump trailers, commercial and industrial burners, combustion control systems, storage equipment and related parts to the oil and gas, construction, and water well industries. RexCon, Inc. was added to this group effective October 1, 2017 as described below.

Individual Company subsidiaries included in the composition of the Company's segments are as follows:

1. Infrastructure Group – Astec, Inc., Roadtec, Inc., Carlson Paving Products, Inc., Astec Australia, Pty Ltd and Astec Mobile Machinery GmbH.

2. Aggregate and Mining Group – Telsmith, Inc., Kolberg-Pioneer, Inc., Johnson Crushers International, Inc., Osborn Engineered Products SA (Pty) Ltd, Breaker Technology, Inc., Astec Mobile Screens, Inc., Astec do Brasil Fabricacao de Equipamentos LTDA and Telestack Limited.

A-5

3. Energy Group – Heatec, Inc., CEI, Inc., GEFCO, Inc., Peterson Pacific Corp., Power Flame Incorporated (beginning in August 2016) and RexCon, Inc. (beginning in October 2017). RexCon, Inc., a manufacturer of high-quality stationary and portable, central mix and ready mix concrete batch plants, concrete mixers and concrete paving equipment, was added to this group effective October 1, 2017 upon the acquisition of substantially all of the assets and liabilities of RexCon LLC.

The Company also has one other category, Corporate, that contains the business units that do not meet the requirements for separate disclosure as a separate operating segment or inclusion in one of the other reporting segments. The business units in the Corporate category are Astec Insurance Company ("Astec Insurance" or "the captive") and Astec Industries, Inc., the parent company. These two companies provide support and corporate oversight for all the companies that fall within the reportable operating segments.

The Company's financial performance is affected by a number of factors, including the cyclical nature and varying conditions of the markets it serves. Demand in these markets fluctuates in response to overall economic conditions and is particularly sensitive to the amount of public sector spending on infrastructure development, privately funded infrastructure development, changes in the price of crude oil, which affects the cost of fuel and liquid asphalt and changes in the price of steel.

The Company believes that federal highway funding influences the purchasing decisions of the Company's customers, who are typically more comfortable making capital equipment purchases with long-term federal legislation in place. Federal funding provides for approximately 25% of all highway, street, roadway and parking construction in the United States.

In July 2012, the "Moving Ahead for Progress in the 21st Century Act" ("Map-21") was approved by the U.S. federal government, which authorized $105 billion of federal spending on highway and public transportation programs through fiscal year 2014. In August 2014, the U.S. government approved short-term funding of $10.8 billion through May 2015. Federal transportation funding operated on short-term appropriations until December 4, 2015 when the Fixing America's Surface Transportation Act ("FAST Act") was signed into law. The $305 billion FAST Act approved funding for highways of approximately $205 billion and transit projects of approximately $48 billion for the five-year period ending September 30, 2020.

The Company believes a multi-year highway program (such as the FAST Act) will have the greatest positive impact on the road construction industry and allow its customers to plan and execute longer-term projects, but given the inherent uncertainty in the political process, the level of governmental funding for federal highway projects will similarly continue to be uncertain. Since elected in late 2016, the current executive branch of the federal government has stressed that one of its priorities is a new infrastructure bill including increased funding for roads, bridges, tunnels, airports, railroads, ports and waterways, pipelines, clean water infrastructure, energy infrastructure and telecommunication needs. The funding for the bill as proposed would rely in part on direct federal spending as well as increased private sector funding in exchange for federal tax credits. Governmental funding that is committed or earmarked for federal highway projects is always subject to repeal or reduction. Although continued funding under the FAST Act or funding of a bill passed by the new administration is expected, it may be at lower levels than originally approved or anticipated. In addition, Congress could pass legislation in future sessions that would allow for the diversion of previously appropriated highway funds for other purposes, or it could restrict funding of infrastructure projects unless states comply with certain federal policies. The level of future federal highway construction is uncertain and any future funding may be at levels lower than those currently approved or that have been approved in the past.

The public sector spending described above is needed to fund road, bridge and mass transit improvements. The Company believes that increased funding is unquestionably needed to restore the nation's highways to a quality level required for safety, fuel efficiency and mitigation of congestion. In the Company's opinion, amounts needed for such improvements are significantly greater than amounts approved to date, and funding mechanisms such as the federal usage fee per gallon of gasoline, which is still at the 1993 level of 18.4 cents per gallon, would likely need to be increased along with other measures to generate the funds needed.

A-6

In addition to public sector funding, the economies in the markets the Company serves, the price of oil and its impact on customers' purchasing decisions and the price of steel may each affect the Company's financial performance. Economic downturns generally result in decreased purchasing by the Company's customers, which, in turn, causes reductions in sales and increased pricing pressure on the Company's products. Rising interest rates also typically negatively impact customers' attitudes toward purchasing equipment. The Federal Reserve has maintained historically low interest rates in response to the economic downturn which began in 2009; however, the Federal Reserve raised the Federal Funds Rate in 2016 and again in March, June and December 2017, and may implement additional increases in the future.

Significant portions of the Company's revenues from the Infrastructure Group relate to the sale of equipment involved in the production, handling, recycling or installation of asphalt mix. Liquid asphalt is a by-product of oil production. An increase or decrease in the price of oil impacts the cost of asphalt, which is likely to alter demand for asphalt and therefore affect demand for certain Company products. While increasing oil prices may have a negative financial impact on many of the Company's customers, the Company's equipment can use a significant amount of recycled asphalt pavement, thereby partially mitigating the effect of increased oil prices on the final cost of asphalt for the customer. The Company continues to develop products and initiatives to reduce the amount of oil and related products required to produce asphalt mix. Oil price volatility makes it difficult to predict the costs of oil-based products used in road construction such as liquid asphalt and gasoline. Oil prices rose during much of 2016 and continued to fluctuate during 2017 and fluctuations are expected to continue in the future. Minor fluctuations in oil prices should not have a significant impact on customers' buying decisions. Other factors such as political uncertainty in oil producing countries, interruptions in oil production due to disasters, whether natural or man-made, or other economic factors could significantly impact oil prices, which could negatively impact demand for the Company's products. However, the Company believes the continued funding of the FAST Act federal highway bill passed in December 2015 has greater potential to impact the buying decisions of the Company's customers than does the fluctuation of oil prices in 2018.

Contrary to the impact of oil prices on many of the Company's Infrastructure Group products as discussed above, the products manufactured by the Energy Group, which are used in drilling for oil and natural gas, in heaters for refineries and oil sands and in double fluid pump trailers for fracking and oil and gas extraction, would benefit from higher oil and natural gas prices, to the extent that such higher prices lead to increased development in the oil and natural gas production industries. The Company believes further development of domestic oil and natural gas production capabilities is needed and would positively impact the domestic economy and the Company's business.

Steel is a major component in the Company's equipment. Steel followed typical seasonal patterns during 2017, peaking in April and reaching lows in November. Prices began to rise in early 2018 and are expected to continue to rise throughout the first and second quarters of 2018 due to seasonal demand and an improving economy. The Company expects normal seasonal price movement during 2018 with steel prices higher on average than in 2017. The Company continues to utilize forward-looking contracts (with no minimum or specified quantity guarantees) coupled with advanced steel purchases to minimize the impact of any price increases. The Company will review the trends in steel prices entering into the second half of 2018 and establish future contract pricing accordingly.

In addition to the factors stated above, many of the Company's markets are highly competitive, and its products compete worldwide with a number of other manufacturers and dealers that produce and sell similar products. From 2010 through mid-2012, a weak U.S. dollar, combined with improving economic conditions in certain foreign economies, had a positive impact on the Company's international sales. From mid-2012 through 2017, the strong U.S. dollar has negatively impacted pricing in certain foreign markets the Company serves. The Company expects the U.S. dollar to remain strong as compared to historical rates in the near term relative to most foreign currencies. Increasing domestic interest rates or weakening economic conditions abroad could cause the U.S. dollar to continue to strengthen, which could negatively impact the Company's international sales.

In the United States and internationally, the Company's equipment is marketed directly to customers as well as through dealers. During 2017, approximately 65% of the Company's sales were to the end user. The Company expects this ratio to be between 60% and 70% for 2018.

The Company is operated on a decentralized basis with a complete management team for each operating subsidiary. Finance, insurance, legal, shareholder relations, corporate accounting and other corporate matters are primarily handled at the corporate level (i.e., Astec Industries, Inc., the parent company). The engineering, design, sales, manufacturing and basic accounting functions are handled at each individual subsidiary. Standard accounting procedures are prescribed and followed in all reporting.

A-7

During 2016, the Company implemented revised profit sharing plans whereby corporate officers, subsidiary presidents and other employees at each subsidiary have the opportunity to earn profit sharing incentives based upon the Company's and/or the individual groups or subsidiaries' return on capital employed, EBITDA margin and safety. Corporate officers' and subsidiary presidents' awards when calculated at targeted performance, are between 35% and 100% of their base salary, depending upon their responsibilities, and the plans allow for awards of up to 200% of the target. Each subsidiary has the opportunity to earn up to 10% of its after-tax profit as a profit-sharing incentive award to be paid to its employees.

The Company also implemented revised long-term incentive plans during 2016 whereby corporate officers, subsidiary presidents and other corporate or subsidiary management employees will be awarded Restricted Stock Units ("RSUs") if certain goals are met based upon the Company's Total Shareholder's Return ("TSR") as compared to a peer group and the Company's pretax profit margin. The grant date value of corporate officers' and subsidiary presidents' awards, when calculated at targeted performance, are between 20% and 100% of their base salary, depending upon their responsibilities, and the plans allow for awards of up to 200% of the target. Additional RSUs may be granted to other key subsidiary management employees based upon individual subsidiary profits.

Results of Operations: 2017 vs. 2016

Net Sales

Net sales increased $37,308 or 3.3% to $1,184,739 in 2017 from $1,147,431 in 2016. Sales are generated primarily from new equipment purchases made by customers for use in construction of privately funded infrastructure, public sector spending on infrastructure and sales of equipment for the aggregate, mining, wood pellet, quarrying and recycling markets, and for oil and gas and geothermal industries. Excluding a decline in domestic wood pellet plant sales discussed below, total sales increased $164,508 between years.

Domestic sales for 2017 were $932,294 or 78.7% of net sales compared to $941,273 or 82.0% of net sales for 2016, a decrease of $8,979 or 1.0%. The decrease in domestic sales was due to a $127,200 decline in pellet plant related sales due to no new orders being received in 2017, offset by increases in sales of most of the Company's other major product lines due to the continuing positive economic conditions in the domestic markets and the impact of the FAST Act funding.

International sales for 2017 were $252,445 or 21.3% of net sales compared to $206,158 or 18.0% of net sales for 2016, an increase of $46,287 or 22.5%. The Company experienced improved markets for most of its major product lines internationally in 2017 compared to 2016 caused by improved global market conditions, the stabilization of the U.S. dollar in certain foreign markets and a slight recovery in the mining and oil and gas sectors. The Company believes its strategy of keeping its sales and service structure in place during the recent downturn aided international sales in 2017. Sales reported by the Company for 2017 would have been $2,884 lower had 2017 foreign exchange rates been the same as 2016 rates. The increase in international sales occurred primarily in Canada, Russia, Australia, Brazil and Africa, offset by sales decline in South America (excluding Brazil), Japan and Mexico. The Company continues its efforts to grow its international business by increasing its presence in the markets it serves.

Parts sales for 2017 were $283,361 or 23.9% of net sales compared to $263,457 or 23.0% of net sales for 2016, an increase of $19,904 or 7.6%. All of the Company's major product lines experienced increased parts sales in 2017 as compared to 2016.

Gross Profit

Gross profit for 2017 was $243,129 or 20.5% of net sales as compared to $265,269 or 23.1% of net sales in 2016, a decline of $22,140 or 8.3%. Due to cost overruns incurred in 2017 by the Company on the installation phase of its customer's Arkansas wood pellet plant sold in 2016 and the identification of design issues its customers' wood pellet plants in Arkansas and Georgia discovered in the third quarter of 2017, the Company experienced an overall reduction in wood pellet plant margins of $60,107 between years. As the Company has financed the sale of the $60,249 Georgia wood pellet plant, revenue from the sale will be recorded when the customer pays for the equipment, which is expected in late 2018. No significant margins are expected to be recorded on the Georgia pellet plant in 2018.

Selling, General and Administrative Expense

Selling, general and administrative expense for 2017 was $160,775 or 13.6% of net sales compared to $153,145 or 13.3% of net sales for 2016, an increase of $7,630 or 5.0% due to an increase of $8,646 in selling expenses resulting primarily from increased ConExpo Show-related costs of $4,355 and other increased costs related to the $164,508 increase in total sales excluding wood pellet plants.

A-8

Research and Development

Research and development expenses increased $1,848 or 7.4% to $26,817 in 2017 from $24,969 in 2016. During 2017, the Company continued its focus on research and development spending for new products as well as improvements to existing product lines and adaptation of those products to other markets.

Interest Expense

Interest expense in 2017 decreased $555 or 39.8%, to $840 from $1,395 in 2016 due to a reduction in debt levels at the Company's subsidiary in Brazil and reduced interest on tax return audit assessments.

Interest Income

Interest income increased $496 or 61.5% to $1,302 in 2017 from $806 in 2016 due primarily to interest received in 2017 from a wood pellet plant customer.

Other Income

Other income increased $689 or 130.2% to $1,218 in 2017 from $529 in 2016 due primarily to a $347 deposit forfeited by a customer on a cancelled order, reduced investment losses of $180 and improved licensing fee income of $105.

Income Tax

Income tax expense for 2017 was $19,627, compared to $32,107 for 2016. The effective tax rates for 2017 and 2016 were 34.3% and 36.9%, respectively. The reduction in tax rates between periods is due primarily to an increase in the percent impact of the Company's Domestic Production Activities Deduction and Research and Development Tax Credit (due to similar dollar impacts on lower taxable earnings) and a $1,056 reduction in income tax expense in the fourth quarter of 2017 due to the application of the provisions of Tax Cuts and Jobs Act of 2017, enacted by the U.S. government on December 22, 2017.

Net Income Attributable To Controlling Interest

The Company had net income attributable to controlling interest of $37,795 in 2017 compared to $55,159 in 2016, a decrease of $17,364, or 31.5%. Earnings per diluted share decreased $0.75 to $1.63 in 2017 from $2.38 in 2016. Weighted average diluted shares outstanding for the years ended December 31, 2017 and 2016 were 23,184 and 23,142, respectively.

Backlog

The backlog of orders at December 31, 2017 was $411,469 compared to $361,831 at December 31, 2016, an increase of $49,638, or 13.7%. Backlogs for both periods include a $60,249 pellet plant order the Company has financed for its customer. Revenue will not be recorded on the order until cash payments are received, which is expected to occur in late 2018. The increase in the backlog of orders was due to an increase in domestic backlog of $36,786 or 12.3% and an increase in international backlog of $12,852 or 20.5%. The Infrastructure Group backlog increased $7,271 or 3.1% from 2016. The Aggregate and Mining Group backlog increased $28,036 or 31.5% from 2016 while the backlog in the Energy Group increased $14,331 or 35.2% over the 2016 levels. The Company is unable to determine whether the changes in backlogs were experienced by the industry as a whole.

A-9

Infrastructure Group: Sales in this group decreased $55,217 or 9.1%. Excluding a $127,500 decrease in wood pellet plant sales, the group's sales increased $71,983 in 2017 as compared to 2016. Domestic sales for the Infrastructure Group decreased $80,666 or 14.7% in 2017 compared to 2016. The decrease in domestic sales was due to a $127,200 decline in pellet plant related sales due to no new orders being received in 2017, offset by increases in sales of most other major product lines due to the continuing positive economic conditions in the domestic markets and the impact of the FAST Act funding. International sales for the Infrastructure Group increased $25,449 or 41.3% in 2017 compared to 2016. The increase in international sales was due primarily to the improved sales of mobile asphalt equipment and increased sales by the Company owned distributor in Australia. The increase in international sales for the Infrastructure Group occurred mainly in Canada, Australia and Russia, offset by a decrease in sales in South America and Japan. Parts sales for the Infrastructure Group increased 3.7% in 2017 compared to 2016.

Aggregate and Mining Group: Sales in this group increased $43,960 or 12.2%. Domestic sales for the Aggregate and Mining Group increased $32,206 or 13.1% in 2017 compared to 2016 primarily due to improved sales into the Company's traditional rock quarry markets, increased sales of the Company's larger aggregate equipment due to the release of pent-up demand and increased sales by the Company's Northern Ireland subsidiary in the U.S. domestic market. International sales for the Aggregate and Mining Group increased $11,754 or 10.3% in 2017 compared to 2016. The increase in international sales is due to an easing of pent-up demand, the Company's continued sales efforts in the international markets and improved sales by the Company's Brazilian subsidiary. The increase in international sales for the Aggregate and Mining Group occurred primarily in Canada, Brazil, Australia, Asia and Africa, offset by sales declines in Mexico, Japan and South America. Parts sales for the Aggregate and Mining Group increased 7.9% in 2017 compared to 2016 due to improved sales by the Company's South African subsidiary and sales into the traditional rock quarry markets.

Energy Group: Sales in this group increased $48,565 or 27.2%. Domestic sales for the Energy Group increased $39,482 or 26.6% in 2017 compared to 2016 due to an increase in sales of $14,739 by Power Flame, which was acquired on August 1, 2016, and improved sales of wood chipping and grinding equipment, drilling rigs and oil and gas pumpers. RexCon, Inc., which was acquired on October 1, 2017, also contributed $2,449 of domestic sales in 2017. International sales for the Energy Group increased $9,083 or 30.0% in 2017 compared to 2016. The increase in international sales was due primarily to increased sales by Power Flame of $3,287 and increased sales of oil and gas drilling rigs. The increase in international sales occurred in Canada, Africa, China, Brazil and the Middle East, offset by decreased sales in South America (excluding Brazil). Parts sales for the Energy Group increased 19.6% in 2017 compared to 2016 due to increased sales in all major product lines.

Infrastructure Group: Profit for this group decreased $44,841 or 62.7% from 2016. This group's profits were impacted by a decrease in gross profit of $42,821 or 550 basis points. Due to cost overruns incurred by the Company in 2017 on the installation phase of its customer's Arkansas wood pellet plant sold in 2016 and the identification of design issues its customers' wood pellet plants in Arkansas and Georgia discovered in the third quarter of 2017, the Company experienced an overall reduction in wood pellet plant margins of $60,107 between years. As the Company has financed the sale of the Georgia wood pellet plant, revenue from the sale will be recorded when the customer pays for the equipment, which is expected in late 2018. No significant margins are expected to be recorded on the Georgia pellet plant in 2018. Segment profits were also negatively impacted by a $3,448 increase in selling expenses, including $1,986 related to the ConExpo Show and other cost increases related to the $71,983 increase in group sales, excluding wood pellet plants. Research and development costs also increased by $1,475 between periods.

Aggregate and Mining Group: Profit for this group increased $871 or 2.5% from 2016. This group's profits were impacted by an increase in gross profit of $2,440 on increased sales of $43,960, offset by a 220 basis point decrease in gross margin due to intercompany profit eliminations, product mix considerations and reduced margins at the Company's Northern Ireland subsidiary. The group's profits were also negatively impacted by increased ConExpo Show costs of $1,842.

A-10

Energy Group: Profit for this group increased $12,074 or 291.3% from 2016. This group's profits were impacted by an increase in gross profit of $17,954 on increased sales of $48,565 and a 330 basis point increase in gross margins. Margins were favorably impacted by significant improvements at the Company's GEFCO subsidiary, due to a 64% increase in sales, and by the addition of Power Flame, which was acquired on August 1, 2016. The group's profits were negatively impacted by a $5,540 increase in selling, general and administrative expenses, of which $3,280 relates to additional costs incurred by Power Flame and RexCon, which were acquired in 2016 and 2017, respectively.

Corporate: Net corporate expenses decreased $15,029 from 2016 due to decreases in profit sharing and SERP expenses of $5,031 and decreased income taxes of $10,617.

Results of Operations: 2016 vs. 2015

Net Sales

Net sales increased $164,274 or 16.7% to $1,147,431 in 2016 from $983,157 in 2015. Sales are generated primarily from new equipment purchases made by customers for use in construction of privately funded infrastructure, public sector spending on infrastructure and sales of equipment for the aggregate, mining, wood pellet, quarrying and recycling markets, and for oil and gas and geothermal industries.

Domestic sales for 2016 were $941,273 or 82.0% of net sales compared to $722,287 or 73.5% of net sales for 2015, an increase of $218,985 or 30.3%. The overall increase in domestic sales for 2016 compared to 2015 reflects the strengthening economic conditions for the Company's products in the domestic market and a $135,187 increase in wood pellet plant sales between years.

International sales for 2016 were $206,158 or 18.0% of net sales compared to $260,870 or 26.5% of net sales for 2015, a decrease of $54,711 or 21.0%. The Company continued to experience a challenging market for its products internationally in 2016 compared to 2015 caused by competitive pressures due to the strengthening of the U.S. dollar, as we compete with local manufacturers that do not price their products based on the U.S. dollar and the continued sluggishness in the global mining industry. Sales reported by the Company for 2016 would have been $10,148 higher had 2016 foreign exchange rates been the same as 2015 rates. The Company continues its efforts to grow its international business by increasing its presence in the markets it serves.

Parts sales as a percentage of net sales decreased 400 basis points to 23.0% in 2016 from 27.0% in 2015. Parts sales decreased 0.6% to $263,457 in 2016 from $265,092 in 2015.

Gross Profit

Gross profit as a percentage of sales increased to 23.1% in 2016 as compared to 22.3% in 2015. Gross profit increased 21.2% to $265,269 in 2016 from $218,843 in 2015. Gross margins increased in 2016 due to a release of pent-up demand from the lack of a long-term federal highway bill, which led to increased margins in the Infrastructure Group as well as margins recorded for wood pellet plant sales by the Company.

Selling, General and Administrative Expense

Selling, general and administrative expense for 2016 was $153,145 or 13.3% of net sales compared to $145,180 or 14.8% of net sales for 2015, an increase of $7,965 or 5.5%.The increase in selling, general and administrative expense over 2015 was due to an increase in payroll and related expense of $6,263 and an increase of $7,640 in profit sharing and SERP expenses, offset by a reduction in the cost of repairs and maintenance, primarily on Company airplanes of $3,001, a decrease in consultant fees of $789 and a decrease in computer expenses of $874.

Research and Development

Research and development expenses increased $1,293 or 5.5% to $24,969 in 2016 from $23,676 in 2015. During 2016, the Company continued its focus on research and development spending for new products as well as improvements to existing product lines and adaptation of those products to other markets. The Company will introduce many of its new products at the ConExpo Show to be held in March 2017.

Interest Expense

Interest expense in 2016 decreased $216 or 13.4%, to $1,395 from $1,611 in 2015.

Interest Income

Interest income increased $264 or 48.7% to $806 in 2016 from $542 in 2015.

A-11

Other Income

Other income was $529 in 2016 compared to $3,055 in 2015, a decrease of $2,526 or 82.7% due to $1,204 of income from key-man life insurance policies received in 2015 resulting from the death of the Company's Chairman (and former CEO) and the forfeiture of a customer deposit of $1,002 in 2015 on a cancelled order.

Income Tax

Income tax expense for 2016 was $32,107, compared to $20,007 for 2015. The effective tax rates for 2016 and 2015 were 36.9% and 38.5%, respectively. The effective tax rate decreased in 2016 from the 2015 effective tax rate due to an increase in domestic tax credits for research and development expenditures, a decrease in the overall effective state rate caused by changes in apportionment and statutory state rates and a reduced impact of valuation allowances on deferred tax assets.

Net Income Attributable To Controlling Interest

The Company had net income attributable to controlling interest of $55,159 in 2016 compared to $32,797 in 2015, an increase of $22,362, or 68.2%. Earnings per diluted share increased $0.96 to $2.38 in 2016 from $1.42 in 2015. Weighted average diluted shares outstanding for the years ended December 31, 2016 and 2015 were 23,142 and 23,120, respectively.

Backlog

The backlog of orders at December 31, 2016 was $357,367 compared to $315,910 at December 31, 2015, an increase of $41,457, or 13.1%. The increase in the backlog of orders was due to an increase in domestic backlog of $33,006 or 12.6% and an increase in international backlog of $8,451 or 15.6%. The Infrastructure Group backlog increased $28,394 or 13.9% from 2015. The Infrastructure Group backlog includes $60,249 in both 2016 and 2015 for the first three-line pellet plant order from a single customer under a Company financed arrangement whereby the Company expects to record the related revenues in 2018 when payment is due to be received. The Infrastructure Group believes the FAST Act federal highway funding bill passed in late 2015, continues to positively impact order backlogs of the group. The Aggregate and Mining Group backlog increased $14,467 or 19.5% from 2015 while the backlog in the Energy Group decreased $1,404 or 3.7% over the 2015 levels. Both the Aggregate and Mining Group and the Energy Group continue to be negatively impacted by competitive pricing issues in many foreign countries due to the strength of the U.S. dollar compared to foreign currencies, and reduced demand for equipment in the mining and oil and gas industries. The Company is unable to determine whether the changes in backlogs were experienced by the industry as a whole.

Net Sales by Segment

	2016		2015		$ Change			% Change
Infrastructure Group	$	608,908	$	428,737	$	180,171			42.0	%

Energy Group		178,763		183,607		(4,844	)		(2.6	)%

Infrastructure Group: Sales in this group increased $180,171 or 42.0%. Domestic sales for the Infrastructure Group increased 55.2% in 2016 compared to 2015 due to a release of some of the pent-up demand from the lack of a long-term federal highway bill for most of 2015 and increased pellet plant sales of $135,187. International sales for the Infrastructure Group decreased 19.2% in 2016 compared to 2015. The decrease in international sales was due primarily to the strengthening of the U.S. dollar compared to the currencies in many of the countries in which the Company operates. The decrease in international sales for the Infrastructure Group occurred mainly in Canada, Europe, the Middle East, Post-Soviet States, South America and Asia, offset by an increase in sales in the Mexico, Japan, Australia, West Indies, China and Central America. Parts sales for the Infrastructure Group increased 5.7% in 2016 compared to 2015. The Company believes the increase in parts sales from 2015 to 2016 was due to the impact of the FAST Act federal highway bill passed in late 2015. The Company also believes a portion of the increase in parts sales was attributed to sales of replacement parts for our competitors' equipment.

Aggregate and Mining Group: Sales in this group decreased $11,053 or 3.0%. Domestic sales for the Aggregate and Mining Group increased 6.3% in 2016 compared to 2015 primarily due to improved demand related to infrastructure projects. International sales for the Aggregate and Mining Group decreased 18.3% in 2016 compared to 2015. The decrease in international sales is due to the strength of the U.S. dollar compared to the currencies in many of the countries in which the Company operates and the continuing slowdown in the mining industry. The decrease in international sales for the Aggregate and Mining Group occurred primarily in Africa, the Middle East, Canada, Brazil, Russia and India, offset by increases in Mexico, Japan, Europe and Asia. Sales reported by the Company's foreign subsidiaries in this group would have been $10,134 higher had foreign exchange rates for 2016 been the same as 2015 rates. Parts sales for the Aggregate and Mining Group decreased 6.4% in 2016 compared to 2015.

A-12

Energy Group: Sales in this group decreased $4,844 or 2.6%. Sales in this group were positively affected by the purchase of Power Flame Incorporated (PFI), located in Parsons, Kansas in August 2016. PFI manufactures and sells gas, oil and combination gas/oil and low NOx burners as well as combustion control systems designed for commercial, industrial and process applications. Without the purchase of PFI, sales would have decreased 10% from 2015 to 2016. Domestic sales for the Energy Group increased 6.9% in 2016 compared to 2015. International sales for the Energy Group decreased 32.3% in 2016 compared to 2015. The decrease in international sales was due primarily to the continued strength of the U.S. dollar in 2016 and a continued reduction in oil production and exploration brought on by the low oil prices. The decrease in international sales occurred in Russia, the Middle East, Australia, Asia, Africa and Brazil, offset by increased sales in Japan and China. Parts sales for the Energy Group decreased 4.8% in 2016 compared to 2015.

Infrastructure Group: Profit for this group increased $37,592 or 110.9% from 2015. This group's profits were impacted by an increase in gross profit of $42,884 or 60 basis points on increased sales of $180,171 partially due to increased overhead absorption on a 20% increase in direct labor hours worked from 2015 to 2016, offset by an increase in payroll and related expenses of $5,692.

Aggregate and Mining Group: Profit for this group increased $4,187 or 13.6% from 2015. This group's profits were impacted by an increase in gross profit of $1,851 on decreased sales of $11,053 due to a 130 basis point increase in gross margin and decreases in payroll and related expense of $1,329, decreased travel expense of $786 and a $528 decrease in repairs and maintenance expense, primarily on a company airplane.

Energy Group: Profit for this group increased $536 or 14.9% from 2015. This group's profits were impacted by an increase in gross profit of $2,077 on decreased sales of $4,844 due to a 170 basis point increase in gross margin and decreased outside service expense of $741, repairs and maintenance of $346 and computer expense of $235.

Corporate: Net corporate expenses increased $19,369 from 2015 due to increases in profit sharing and SERP expense of $7,640, stock incentive expense of $1,376, and increased income taxes of $9,826.

Liquidity and Capital Resources

The Company's primary sources of liquidity and capital resources are its cash on hand, borrowing capacity under a $100,000 revolving credit facility with a lender and cash flows from operations. The Company had $62,280 (of which $22,064 was held by our foreign subsidiaries) of cash available for operating purposes at December 31, 2017. The Company had outstanding letters of credit of $9,757 and borrowing availability of $90,243 under the credit facility as of December 31, 2017. The Company had no outstanding borrowings at any time during 2017 under this facility. Borrowings under the Company's credit agreement are subject to an interest rate equal to the daily one-month LIBOR rate plus a 0.75% margin, resulting in a rate of 2.32% at December 31, 2017. The credit agreement contains certain financial covenants, including provisions concerning required levels of annual net income, minimum tangible net worth and maximum allowed capital expenditures. The Company was in compliance with these covenants as of December 31, 2017.

The Company's South African subsidiary, Osborn Engineered Products SA (Pty) Ltd ("Osborn"), has a credit facility of $7,672 with a South African bank to finance short-term working capital needs, as well as to cover performance letters of credit, advance payment and retention guarantees. As of December 31, 2017, Osborn had no outstanding borrowings, but had $813 in performance, advance payment and retention guarantees outstanding under the facility. The facility has been guaranteed by Astec Industries, Inc., but is otherwise unsecured. A 0.75% unused facility fee is charged if less than 50% of the facility is utilized. As of December 31, 2017, Osborn had available credit under the facility of $6,859. The interest rate is 0.25% less than the South Africa prime rate, resulting in a rate of 10.0% as of December 31, 2017.

A-14

Financing activities used cash of $16,792 in 2017 and $11,020 in 2016 for an increase of $5,772. The change is primarily due to reduced borrowings and increased debt repayments by the Company's Brazilian and South African subsidiaries.

Approved capital expenditures for 2018 total $35,398, including facility additions at the Company's Roadtec and Carlson subsidiaries. The remaining approved capital expenditures are for various purchases of machinery and equipment, automobiles and technology related spending to meet the needs across all Company subsidiaries. The Company expects to finance these expenditures using currently available cash balances, internally generated funds and available credit under the Company's credit facility.

Financial Condition

The Company's current assets increased to $602,969 at December 31, 2017 from $576,833 at December 31, 2016, an increase of $26,136. The increase is due to increases in inventories of $30,975 and accounts receivable of $9,279 due to increased order and sales volumes, offset by decreases in cash and cash equivalents of $20,091. Additionally, accounts receivable days outstanding increased from 30.5 in 2016 to 34.3 in 2017.

The Company's current liabilities increased to $179,146 at December 31, 2017 from $168,861 at December 31, 2016, an increase of $10,285. The increase is primarily due to increases in customer deposits of $10,279 and accounts payable of $3,120.

Market Risk and Risk Management Policies

The Company is exposed to changes in interest rates, primarily from its revolving credit agreements. A hypothetical 100 basis point adverse move (increase) in interest rates would not have materially affected interest expense for the years ended December 31, 2017 and 2016, due to minimal borrowings during the periods. The Company does not hedge variable interest.

The Company is subject to foreign exchange risk at its foreign operations. Foreign operations represent 15.9% and 15.8% of total assets at December 31, 2017 and 2016, respectively, and 10.8% and 9.5% of total net sales for the years ended December 31, 2017 and 2016, respectively. Each period, the balance sheets and related results of operations of the Company's foreign subsidiaries are translated from their functional foreign currency into U.S. dollars for reporting purposes. As the U.S. dollar strengthens against those foreign currencies, the foreign denominated net assets and operating results become less valuable in the Company's reporting currency. When the U.S. dollar weakens against those currencies, the foreign denominated net assets and operating results become more valuable in the Company's reporting currency. At each reporting date, the fluctuation in the value of the net assets and operating results due to foreign exchange rate changes is recorded as an adjustment to other comprehensive income (loss) in equity. The Company views its investments in foreign subsidiaries as long-term and does not hedge the net investments in foreign subsidiaries.

From time to time, the Company's foreign subsidiaries enter into transactions not denominated in their functional currency. In these situations, the Company evaluates the need to hedge those transactions against foreign currency rate fluctuations. When the Company determines a need to hedge a transaction, the subsidiary enters into a foreign currency exchange contract. The Company does not apply hedge accounting to these contracts and, therefore, recognizes the fair value of these contracts in the consolidated balance sheets and the change in the fair value of the contracts in current earnings.

Due to the limited exposure to foreign exchange rate risk, a 10% fluctuation in the foreign exchange rates at December 31, 2017 or 2016 would not have a material impact on the Company's consolidated financial statements.

Contractual Obligations

Contractual obligations and the period in which payments are due as of December 31, 2017 are as follows:

	Payments Due by Period
Contractual Obligations	Total		Less Than 1 Year		Years 2 to 3		Years 4 to 5		More Than 5 Years
Operating lease obligations	$	6,263	$	2,146	$	2,971	$	913	$	233
Inventory purchase obligations		3,951		3,951		--		--		--
Debt obligations		4,044		2,469		980		502		93
Total	$	14,258	$	8,566	$	3,951	$	1,415	$	326

A-15

The above table excludes the Company's liability for unrecognized tax benefits, which totaled $365 at December 31, 2017, since the timing of cash settlements to the respective taxing authorities cannot be reliably predicted.

In 2017 and 2016, the Company made contributions of approximately $415 to its pension plan. The Company has no planned contributions to the pension plan in 2018. The Company's funding policy is to make at least the minimum annual contributions required by applicable regulations.

Contingencies

Management has reviewed all claims and lawsuits and has made adequate provision for any losses that can be reasonably estimated. Based upon currently available information and with the advice of counsel, management believes that the ultimate outcome of its current claims and legal proceedings, individually and in the aggregate, will not have a material adverse effect on the Company's financial position, cash flows or results of operations. However, claims and legal proceedings are subject to inherent uncertainties and rulings unfavorable to the Company could occur. If an unfavorable ruling were to occur, there exists the possibility of a material adverse effect on the Company's financial position, cash flows or results of operations.

Certain customers have financed purchases of the Company's products through arrangements in which the Company is contingently liable for customer debt aggregating $3,805 at December 31, 2017. These obligations have average remaining terms of 1.8 years. The Company has recorded a liability of $836 related to these guarantees at December 31, 2017.

The Company is contingently liable under letters of credit of approximately $13,314, primarily for performance guarantees to customers, banks or insurance carriers.

The Company has a sales contract with the purchaser of a large wood pellet plant, on which revenues of $7,987 and $135,187 were recorded in 2017 and 2016, respectively. As the plant has not yet met the production output and the operational specifications set forth in the original contract, as amended through December 31, 2017, the Company entered into a contract amendment in February 2018, whereby the Company agreed to compensate the customer for production shortfalls caused by the Company and other potential costs (depending upon the market price of wood pellets), from January 1, 2018 through June 15, 2018. The Company incurred production shortfalls in January and February 2018. The Company expects to meet the contract's operational specifications prior to June 15, 2018.

Off-balance Sheet Arrangements

As of December 31, 2017, the Company does not have off-balance sheet arrangements as defined by Item 303(a)(4) of Regulation S-K.

Critical Accounting Policies and Estimates

The Company's consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles. Application of these principles requires the Company to make estimates and judgments that affect the amounts as reported in the consolidated financial statements. Accounting policies that are critical to aid in understanding and evaluating the results of operations and financial position of the Company include the following:

Inventory Valuation: Inventories are valued at the lower of first-in first-out cost or net realizable value. The most significant component of the Company's inventories is steel. Open market prices, which are subject to volatility, determine the cost of steel for the Company. During periods when open market prices decline, the Company may need to reduce the carrying value of the inventory. In addition, certain items in inventory become obsolete over time, and the Company reduces the carrying value of these items to their net realizable value. These reductions are determined by the Company based on estimates, assumptions and judgments made from the information available at that time. See Note 1, Summary of Significant Accounting Policies, for a description of the process used by the Company to value inventories at the lower of first-in first-out cost or market. The Company does not believe it is reasonably likely that the inventory values will materially change in the near future.

A-16

Product Warranty Reserve: The Company accrues for the estimated cost of product warranties at the time revenue is recognized. Warranty obligations by product line or model are evaluated based on historical warranty claims experience. For machines, the Company's standard product warranty terms generally include post-sales support and repairs of products at no additional charge for periods ranging from three months to two years or up to a specified number of hours of operation. For parts from component suppliers, the Company relies on the original manufacturer's warranty that accompanies those parts. Generally, fabricated parts are not covered by specific warranty terms. Although failure of fabricated parts due to material or workmanship is rare, if it occurs, the Company's policy is to replace fabricated parts at no additional charge.

The Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of component suppliers. Estimated warranty obligations are based upon warranty terms, product failure rates, repair costs and current period machine shipments. If actual product failure rates, repair costs, service delivery costs or post-sales support costs differ from estimates, revisions to the estimated warranty liability would be required. The Company does not believe it is reasonably likely that the warranty reserve will materially change in the near future.

Revenue Recognition: Revenue is generally recognized on sales at the point in time when persuasive evidence of an arrangement exists, the price is fixed or determinable, the product has been delivered or services have been rendered and there is reasonable assurance of collection of the sales proceeds. The Company generally obtains purchase authorizations from its customers for a specified amount of product at a specified price with specified delivery terms. A significant portion of the Company's equipment sales represents equipment produced in the Company's plants under short-term contracts for a specific customer project or equipment designed to meet a customer's specific requirements. Most of the equipment sold by the Company is based on standard configurations, some of which are modified to meet customer needs or specifications. The Company provides customers with technical design and performance specifications and performs pre-shipment testing to ensure the equipment performs according to design specifications, regardless of whether the Company provides installation services in addition to selling the equipment.

Certain contracts include terms and conditions through which the Company recognizes revenues upon completion of equipment production, which is subsequently stored at the Company's plant at the customer's request. Revenue is recorded on such contracts upon the customer's assumption of title and risk of ownership and when collectability is reasonably assured. In addition, there must be a fixed schedule of delivery of the goods consistent with the customer's business practices, the Company must not have retained any specific performance obligations such that the earnings process is not complete and the goods must have been segregated from the Company's inventory prior to revenue recognition.

The Company has certain sales accounted for as multiple-element arrangements, whereby revenue attributable to the sale of a product is recognized when the product is shipped, and the revenue attributable to services provided with respect to the product (such as installation services) is recognized when the service is performed. Consideration is allocated to deliverables using the relative selling price method and vendor specific objective evidence, if it exists. Otherwise, the Company uses third-party evidence of selling price or the Company's best estimate of the selling price for the deliverables. The Company evaluates sales with multiple deliverable elements (such as an agreement to deliver equipment and related installation services) to determine whether revenue related to individual elements should be recognized separately, or as a combined unit. In addition to the previously mentioned general revenue recognition criteria, the Company only recognizes revenue on individual delivered elements when there is objective and reliable evidence that the delivered element has a determinable value to the customer on a standalone basis and there is no right of return.

The Company has certain sales accounted for under the percentage of completion method using the ratio of costs incurred to estimated total costs. Revenue, in an amount equal to cost incurred, is recognized until there is sufficient information to determine the estimated profit on the project with a reasonable level of certainty. The factors considered in this evaluation include the stage of design completion, the stage of equipment manufacturing completion, the state of construction completion, the status of outstanding subcontracts, certainty of quantities of labor and materials, certainty of schedule and the relationship with the customer.

A-17

Goodwill and Other Intangible Assets: Intangible assets are classified into two categories: (1) intangible assets with definite lives subject to amortization, and (2) goodwill. Intangible assets with definite lives are tested for impairment if conditions exist that indicate the carrying value may not be recoverable. Risk factors that may be considered include an economic downturn in the general economy, a geographic market or the commercial and residential construction industries, a change in the assessment of future operations as well as the cyclical nature of our industry and the customization of the equipment we sell, each of which may cause adverse fluctuations in operating results. Other risk factors considered would be an increase in the price or a decrease in the availability of oil that could reduce the demand for our products in addition to the significant fluctuations in the purchase price of raw materials that could have a negative impact on the cost of production and gross margins as well as others more fully described in the Risk Factors section of our Form 10-K. An impairment charge is recorded when the carrying value of the definite lived intangible asset is not recoverable by the cash flows generated from the use of the asset. Some of the inputs used in the impairment testing are highly subjective and are affected by changes in business factors and other conditions. Changes in any of the inputs could have an effect on future tests and result in impairment charges.

Goodwill is not amortized but is tested for impairment annually or more frequently if events or circumstances indicate that such intangible assets or goodwill might be impaired. See Note 1, Summary of Significant Accounting Policies, for a description of testing performed by the Company to determine if the recorded value of intangible assets or goodwill has been impaired.

The useful lives of identifiable intangible assets are determined after considering the specific facts and circumstances related to each intangible asset. Factors considered when determining useful lives include the contractual term of any agreement, the history of the asset, the Company's long-term strategy for the use of the asset, any laws or other local regulations which could impact the useful life of the asset, and other economic factors, including competition and specific market conditions. Intangible assets that are deemed to have definite lives are amortized, generally on a straight-line basis, over their useful lives, ranging from 5 to 19 years.

Income Taxes: The Company accounts for income taxes under the guidance of FASB Accounting Standards Codification Topic 740-10, "Income Taxes". Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. A valuation allowance, that represents a reserve on deferred tax assets for which utilization is not more likely than not, is recorded. Judgment is required in determining the provision for income taxes, deferred tax assets and liabilities and the valuation allowance recorded against net deferred tax assets. Income tax contingency accruals are determined and recorded under the guidance of ASC Topic 740-10. Liabilities for uncertain income tax positions are based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step requires an estimate and measurement of the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. It is inherently difficult and subjective to estimate such amounts, as the Company must determine the probability of various possible outcomes. We reevaluate these uncertain tax positions on a quarterly basis or when new information becomes available. These reevaluations are based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, successfully settled issues under audit, expirations due to statutes, and new audit activity. Such a change in recognition or measurement could result in the recognition of a tax benefit or an increase to accrued taxes.

U.S. Tax Reform: On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the "Tax Act") was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a federal corporate tax rate decrease from 35% to 21% for tax years beginning after December 31, 2017, the transition of U.S international taxation from a worldwide tax system to a territorial system and a one-time transition tax on the mandatory deemed repatriation of foreign earnings. The Company's fourth quarter 2017 provision for income taxes was reduced by $1,056, (comprised of a $1,548 reduction in income tax expense recorded in connection with the remeasurement of deferred tax assets and liabilities and $492 of additional income tax expense recorded in connection with the transition tax on the mandatory deemed repatriation of foreign earnings) due to applying the provisions of the Tax Act.

A-18

On December 22, 2017, Staff Accounting Bulletin No. 118 ("SAB 118") was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Act. In accordance with SAB 118, the Company determined that the $492 additional 2017 income tax expense discussed above is a provisional amount and constitutes a reasonable estimate at December 31, 2017, based upon the best information currently available. The ultimate impact may differ from the provisional amount, possibly materially, due to, among other things, additional analysis, changes in interpretations and assumptions the Company has made, additional regulatory guidance that may be issued and actions the Company may take as a result of the Tax Act. Any subsequent adjustment to the amount will be recorded to current tax expense when the analysis is complete, which is expected in 2018 shortly after the filing of the Company's 2017 U.S. income tax return.

Beginning in 2018, the Company expects that its effective tax rate will be reduced by approximately 11% from its historic average due to the effects of the Tax Act, resulting in an effective tax rate ranging from 23% to 25% in a typical year. The primary drivers of this are the reduced U.S. federal tax rate and the elimination of the benefit for the domestic production activities deduction which is repealed by the Tax Act.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ('FASB") issued Accounting Standards Update ("ASU") No. 2014-09, "Revenue from Contracts with Customers", which supersedes existing revenue guidance under U.S. GAAP. The standard's core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The implementation of this new standard will require companies to use more judgment and to make more estimates than under current guidance and to expand their disclosures to include information regarding contract assets and liabilities as well as a more disaggregated view of revenue. The standard, as amended, is effective for public companies for annual periods beginning after December 15, 2017. The Company adopted the new standard effective January 1, 2018 using the modified retrospective transition method and will expand its disclosures in the first quarter 2018 consolidated financial statements to comply with the disclosure provisions of the new rule. The Company does not expect the adoption of the standard to have a material impact on its financial position, results of operations or cash flows.

In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments-Overall (Subtopic 825-10)", which requires, among other things, equity investments with readily determinable fair values, except those accounted for under the equity method of accounting or those that result in consolidation of the investee, to be measured at fair value with changes in fair value recognized in net income. The standard is effective for public companies in fiscal years beginning after December 15, 2017, and the Company adopted the standard effective January 1, 2018. The Company does not expect the adoption of this standard to have a material impact on the Company's financial position, results of operations or cash flows.

In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)", which significantly changes the accounting for operating leases by lessees. The accounting applied by lessors is largely unchanged from that applied under previous guidance. The new guidance requires lessees to recognize lease assets and lease liabilities in the balance sheet, initially measured at the present value of the lease payments, for leases which were classified as operating leases under previous guidance. Lease cost included in the statement of income will be calculated so that the cost of the lease is allocated over the lease term, generally on a straight-line basis. Lessees may make an accounting policy election to exclude leases with a term of 12 months or less from the requirement to record related assets and liabilities. The new standard is effective for public companies for fiscal years beginning after December 15, 2018. The Company plans to adopt the new standard effective January 1, 2019. The Company does not expect the adoption of this standard to have a material impact on its results of operations or cash flows; however, the Company has not determined the impact the adoption of this new standard will have on its financial position.

In March 2016, the FASB issued ASU No. 2016-08, "Revenue from Contracts with Customers (Topic 606)", which does not change the core principles of ASU No. 2014-09 discussed above, but rather clarifies the implementation guidance in order to eliminate the potential for diversity in practice arising from inconsistent application of the principal versus agent guidance. Under the new guidance, when an entity determines it is a principal in a transaction, the entity recognizes revenue in the gross amount of consideration; however in transactions where an entity determines it is an agent, the entity recognizes revenue in the amount of any fee or commission to which it expects to be entitled. The standard is effective for public companies for annual periods beginning after December 15, 2017. The Company adopted the new standard effective January 1, 2018. The Company does not expect the adoption of this standard to have a material impact on the Company's financial position, results of operations or cash flows.

A-19

In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments". The standard changes how credit losses are measured for most financial assets and certain other instruments that currently are not measured through net income. The standard will require an expected loss model for instruments measured at amortized cost as opposed to the current incurred loss approach. In valuing available for sale debt securities, allowances will be required to be recorded, rather than the current approach of reducing the carrying amount, for other than temporary impairments. A cumulative adjustment to retained earnings is to be recorded as of the beginning of the period of adoption to reflect the impact of applying the provisions of the standard. The standard is effective for public companies for periods beginning after December 15, 2019 and the Company expects to adopt the new standard as of January 1, 2020. The Company has not yet determined what impact, if any, the adoption of this new standard will have on the Company's financial position, results of operations or cash flows.

In August 2016, the FASB issued ASU No. 2016-15, "Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force) which clarifies how certain cash receipts and cash payments should be presented on the statement of cash flows. The statement also addresses how the predominance principle should be applied when cash payments have aspects of more than one class of cash flows. The standard is effective for public companies in fiscal years beginning after December 15, 2017, and the Company adopted the standard effective January 1, 2018. The Company does not expect the adoption of this standard to have a material impact on the Company's consolidated statement of cash flows.

In October 2016, the FASB issued ASU No. 2016-16, "Income Taxes (Topic 740), Intra-Entity Transfers of Assets Other Than Inventory" which requires companies to account for the income tax effects of intercompany sales and transfers of assets other than inventory, such as intangible assets, when the transfer occurs. This is a change from current guidance, which requires companies to defer the income tax effects of intercompany transfers of assets until the asset has been sold to an outside party or otherwise recognized by being depreciated, amortized, or impaired. The new guidance will require companies to defer the income tax effects of only intercompany transfers of inventory. The standard is effective for public companies in fiscal years beginning after December 15, 2017. The Company adopted the new standard effective January 1, 2018. The Company does not expect the adoption of this standard to have a material impact on the Company's financial position, results of operations or cash flows.

In January 2017, the FASB issued ASU No. 2017-01, "Business Combinations (Topic 805), Clarifying the Definition of a Business," which provides additional guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The standard is effective for public companies for annual or interim periods beginning after December 15, 2017. The Company adopted the new standard effective January 1, 2018. The Company does not expect the application of this standard to have a material impact on its financial position, results of operations or cash flows.

In January 2017, the FASB issued ASU No. 2017-04, "Intangibles-Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment," which eliminates Step 2 from the goodwill impairment test for public companies.  Previously, Step 2 measured a goodwill impairment loss by comparing the implied fair value of a reporting unit's goodwill with the carrying amount of that goodwill. The new guidance stipulates that an entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge would be recognized for the amount by which the carrying amount exceeds the reporting unit's fair value, up to the amount of goodwill allocated to the reporting unit. The standard is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019 with early adoption permitted. The Company elected to adopt this standard as of December 31, 2017. The application of this standard did not have a material impact on the Company's financial position, results of operations or cash flows.

In August 2017, the FASB issued ASU No. 2017-12, "Derivatives and Hedging (Topic 815), Targeted Improvements to Hedging Activities", to improve the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements. The new guidance is effective for public companies for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years with early adoption permitted in any interim period after its issuance. The Company plans to adopt the new standard effective January 1, 2019. The Company does not expect the application of this standard to have a material impact on its financial position, results of operations or cash flows.

ASTEC INDUSTRIES, INC.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Astec Industries, Inc. and subsidiaries (the "Company") is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. The 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 U.S. generally accepted accounting principles. The Company's internal control over financial reporting 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 assets of the Company; (ii) 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 (iii) 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 and procedures may deteriorate.

Management, under the supervision and with the participation of the Company's principal executive officer and principal financial officer, has evaluated the effectiveness of the Company's internal control over financial reporting as of December 31, 2017. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission, Internal Control - Integrated Framework (2013). The scope of management's assessment of the effectiveness of the Company's internal control over financial reporting as of December 31, 2017 excluded the business unit that the Company acquired on October 1, 2017 (RexCon, Inc.). The total consolidated assets with respect to the excluded business unit were $29.3 million as of December 31, 2017, and the total consolidated revenues with respect to the excluded business unit were $2.7 million for the year ended December 31, 2017. Management will complete its assessment of the internal control over financial reporting of this newly-acquired operation during 2018. Based on its assessment, management concluded that, as of December 31, 2017, the Company's internal control over financial reporting was effective.

KPMG LLP, the Company's independent registered public accounting firm, has issued an attestation report on the Company's internal control over financial reporting as of December 31, 2017.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors

Astec Industries, Inc.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Astec Industries, Inc. and subsidiaries (the "Company") as of December 31, 2017 and 2016, the related consolidated statements of income, comprehensive income, equity and cash flows for each of the years in the three-year period ended December 31, 2017, and the related notes (collectively, the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2017, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the Company's internal control over financial reporting 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, and our report dated March 1, 2018 expressed an unqualified opinion on the effectiveness of the Company's internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. 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 audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Dollar and share amounts in thousands, except per share amounts unless otherwise specified)

1. Summary of Significant Accounting Policies

Basis of Presentation - The consolidated financial statements include the accounts of Astec Industries, Inc. and its domestic and foreign subsidiaries (the "Company"). The Company's significant wholly-owned and consolidated subsidiaries at December 31, 2017 are as follows:

Astec Australia Pty Ltd	Astec do Brasil Fabricacao de Equipamentos Ltda. (92% owned)
Astec, Inc.	Astec Insurance Company
Astec Mobile Machinery GmbH	Astec Mobile Screens, Inc.
Breaker Technology, Inc.	Breaker Technology Ltd.
Carlson Paving Products, Inc.	CEI Enterprises, Inc.
GEFCO, Inc.	Heatec, Inc.
Johnson Crushers International, Inc.	Kolberg-Pioneer, Inc.
Osborn Engineered Products SA (Pty) Ltd	Peterson Pacific Corp.
(99% owned)	Power Flame Incorporated
RexCon, Inc.	Roadtec, Inc.
Telestack Limited	Telsmith, Inc.

All intercompany accounts and transactions have been eliminated in consolidation. Certain reclassifications have been made to the 2016 consolidated financial statements to conform to the 2017 presentation.

Use of Estimates - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported and disclosed in the financial statements and accompanying notes. Actual results could differ from those estimates.

Foreign Currency Translation - Subsidiaries located in Australia, Brazil, Canada, Germany, Northern Ireland, and South Africa operate primarily using local functional currencies. Accordingly, assets and liabilities of these subsidiaries are translated using exchange rates in effect at the end of the period, and revenues and costs are translated using average exchange rates for the period. The resulting adjustments are presented as a separate component of accumulated other comprehensive loss. Foreign currency transaction gains and losses, net are included in cost of sales and amounted to a gain of $431 in 2017 and losses of $246 and $1,377 in 2016 and 2015, respectively.

Fair Value of Financial Instruments - For cash and cash equivalents, trade receivables, other receivables, revolving debt and accounts payable, the carrying amount approximates the fair value because of the short-term nature of those instruments. Trading equity investments are valued at their estimated fair value based on their quoted market prices and debt securities are valued based upon a mix of observable market prices and model driven prices derived from a matrix of observable market prices for assets with similar characteristics obtained from a nationally recognized third party pricing service.

Financial assets and liabilities are categorized as of the end of each reporting period based upon the level of judgment associated with the inputs used to measure their fair value. The inputs used to measure the fair value are identified in the following hierarchy:

Level 1 -                 Unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 - Unadjusted quoted prices in active markets for similar assets or liabilities; or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active; or inputs other than quoted prices that are observable for the asset or liability.

Level 3 - Inputs reflect management's best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.

A-32

All financial assets and liabilities held by the Company at December 31, 2017 and 2016 are classified as Level 1 or Level 2, as summarized in Note 3, Fair Value Measurements.

Cash and Cash Equivalents - All highly liquid investments with an original maturity of three months or less when purchased are considered to be cash and cash equivalents.

Investments - Investments consist primarily of investment-grade marketable securities. Trading securities are carried at fair value, with unrealized holding gains and losses included in net income. Realized gains and losses are accounted for on the specific identification method. Purchases and sales are recorded on a trade date basis. Management determines the appropriate classification of its investments at the time of acquisition and reevaluates such determination at each balance sheet date.

Concentration of Credit Risk - The Company sells products to a wide variety of customers. Accounts receivable are carried at their outstanding principal amounts, less an allowance for doubtful accounts. The Company extends credit to its customers based on an evaluation of the customers' financial condition generally without requiring collateral, although the Company normally requires advance payments or letters of credit on large equipment orders. Credit risk is driven by conditions within the economy and the industry and is principally dependent on each customer's financial condition. To minimize credit risk, the Company monitors credit levels and financial conditions of customers on a continuing basis. After considering historical trends for uncollectible accounts, current economic conditions and specific customer recent payment history and financial stability, the Company records an allowance for doubtful accounts at a level which management believes is sufficient to cover probable credit losses. Amounts are deemed past due when they exceed the payment terms agreed to by the customer in the sales contract. Past due amounts are charged off when reasonable collection efforts have been exhausted and the amounts are deemed uncollectible by management. As of December 31, 2017, concentrations of credit risk with respect to receivables are limited due to the wide variety of customers.

Allowance for Doubtful Accounts - The following table represents a rollforward of the allowance for doubtful accounts for the years ended December 31, 2017, 2016 and 2015:

	Year Ended December 31
	2017			2016			2015
Allowance balance, beginning of year	$	1,511		$	1,837		$	2,248
Provision		482			280			18
Write offs		(308	)		(560	)		(357	)
Other		31			(46	)		(72	)
Allowance balance, end of year	$	1,716		$	1,511		$	1,837

Inventories - The Company's inventory is comprised of raw materials, work-in-process, finished goods and used equipment.

Raw material inventory is comprised of purchased steel and other purchased items for use in the manufacturing process or held for sale for the after-market parts business. The category also includes the manufacturing cost of completed equipment sub-assemblies produced for either integration into equipment manufactured at a later date or for sale in the Company's after-market parts business.

Work-in-process inventory consists of the value of materials, labor and overhead incurred to date in the manufacturing of incomplete equipment or incomplete equipment sub-assemblies being produced.

Finished goods inventory consists of completed equipment manufactured for sale to customers.

Used equipment inventory consists of equipment accepted in trade or purchased on the open market. The category also includes equipment rented to prospective customers on a short-term or month-to-month basis. Used equipment is valued at the lower of acquired or trade-in cost or net realizable value determined on each separate unit. Each unit of rental equipment is valued at the lower of original manufacturing, acquired or trade-in cost or net realizable value.

A-33

Inventories are valued at the lower of cost (first-in, first-out) or net realizable value, which requires the Company to make specific estimates, assumptions and judgments in determining the amount, if any, of reductions in the valuation of inventories to their net realizable values. The net realizable values of the Company's products are impacted by a number of factors, including changes in the price of steel, competitive sales pricing, quantities of inventories on hand, the age of the individual inventory items, market acceptance of the Company's products, the Company's normal gross margins, actions by our competitors, the condition of our used and rental inventory and general economic factors. Once an inventory item's value has been deemed to be less than cost, a net realizable value allowance is calculated and a new "cost basis" for that item is effectively established. This new cost is retained for that item until such time as the item is disposed of or the Company determines that an additional write-down is necessary. Additional write-downs may be required in the future based upon changes in assumptions due to general economic downturns in the markets in which the Company operates, changes in competitor pricing, new product design or other technological advances introduced by the Company or its competitors and other factors unique to individual inventory items.

The most significant component of the Company's inventory is steel. A significant decline in the market price of steel could result in a decline in the market value of the equipment or parts we sell. During periods of significant declining steel prices, the Company reviews the valuation of its inventories to determine if reductions are needed in the recorded value of inventory on hand to its net realizable value.

The Company reviews the individual items included in its finished goods, used equipment and rental equipment inventory on a model-by-model or unit-by-unit basis to determine if any item's net realizable value is below its carrying value. This analysis is expanded to include items in work-in-process and raw material inventory if factors indicate those items may also be impacted. In performing this review, judgments are made and, in addition to the factors discussed above, additional consideration is given to the age of the specific items of used or rental inventory, prior sales offers or lack thereof, the physical condition of the specific items and general market conditions for the specific items. Additionally, an analysis of raw material inventory is performed to calculate reserves needed for obsolete inventory based upon quantities of items on hand, the age of those items and their recent and expected future usage or sale.

When the Company determines that the value of inventory has become impaired through damage, deterioration, obsolescence, changes in price levels, excessive levels of inventory or other causes, the Company reduces the carrying value to the net realizable value based on estimates, assumptions and judgments made from the information available at that time. Abnormal amounts of idle facility expense, freight, handling cost and wasted materials are recognized as current period charges.

Property and Equipment - Property and equipment is stated at cost. Depreciation is calculated for financial reporting purposes using the straight-line method based on the estimated useful lives of the assets as follows: airplanes (20 years), buildings (40 years) and equipment (3 to 10 years). Both accelerated and straight-line methods are used for tax compliance purposes. Routine repair and maintenance costs and planned major maintenance are expensed when incurred.

Goodwill and Other Intangible Assets - The Company classifies intangible assets as either intangible assets with definite lives subject to amortization or goodwill.

The Company tests intangible assets with definite lives for impairment if conditions exist that indicate the carrying value may not be recoverable. Such conditions may include an economic downturn in a geographic market or a change in the assessment of future operations. An impairment charge is recorded when the carrying value of the definite lived intangible asset is not recoverable by the future undiscounted cash flows expected to be generated from the use of the asset.

The Company determines the useful lives of identifiable intangible assets after considering the specific facts and circumstances related to each intangible asset. Factors considered when determining useful lives include the contractual terms of agreements, the history of the asset, the Company's long-term strategy for the use of the asset, any laws or other local regulations which could impact the useful life of the asset, and other economic factors, including competition and specific market conditions. Intangible assets that are deemed to have definite lives are amortized over their useful lives as follows: dealer network and customer relationships: 8-19 years; trade names: 15 years; other: 5-19 years.

Goodwill is not amortized. The Company tests goodwill for impairment annually or more frequently if events or circumstances indicate that goodwill might be impaired. The Company uses qualitative factors to determine whether it is more likely than not (a likelihood of more than 50 percent) that the fair value of a reporting unit is less than its carrying value, including goodwill. The Company estimates the fair values of each of its reporting units using the income approach.

A-34

The income approach uses a reporting unit's projection of estimated future operating results and cash flows which are then discounted using a weighted average cost of capital determined based on current market conditions for the individual reporting unit. The projection uses management's best estimates of cash flows over the projection period based on estimates of annual and terminal growth rates in sales and costs, and changes in operating margins, selling, general and administrative expenses, working capital requirements and capital expenditures. Other factors used in evaluating the fair value of a reporting unit could include deterioration in the general economy, fluctuations in foreign exchange, deterioration in the industry or markets in which the reporting unit operates, an increased competitive market, regulatory or political developments in the market, increases in raw materials, labor costs or other factors that have a negative effect on earnings and cash flows, a decline in actual or budgeted earnings or cash flows, and entity specific changes in management, key personnel, strategy or customer base. If the fair value of a reporting unit is found to be less than its book value, the company will record an impairment loss equal to the excess, if any, of the book value over the fair value of its goodwill.

The fair value of reporting units that do not have goodwill are estimated using either the income or market approaches, depending on which approach is the most appropriate for each reporting unit. The fair value of the reporting units that serve operating units in supporting roles, such as the captive insurance company and the corporate reporting unit are estimated using the cost approach. The sum of the fair values of all reporting units is compared to the fair value of the consolidated Company, calculated using the market approach, which is inferred from the market capitalization of the Company at the date of the valuation, to confirm that the Company's estimation of the fair value of its reporting units is reasonable.

Determining the fair values of the Company's reporting units involves the use of significant estimates and assumptions. Due to the inherent uncertainty involved in making these estimates and assumptions, actual results could differ materially from those estimates.

Impairment of Long-lived Assets - In the event that facts and circumstances indicate the carrying amounts of long-lived assets may be impaired, an evaluation of recoverability is performed. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset are compared to the carrying amount for each asset (or group of assets) to determine if a write-down is required. If this review indicates that the assets will not be recoverable, the carrying values of the impaired assets are reduced to their estimated fair value. Fair value is estimated using discounted cash flows, prices for similar assets or other valuation techniques.

Self-Insurance Reserves - The Company retains the risk for a portion of its workers' compensation claims and general liability claims by way of a captive insurance company, Astec Insurance Company ("Astec Insurance" or the "captive"). Astec Insurance was originally incorporated under the laws of the state of Vermont but was redomiciled to the state of Tennessee in late 2017. The objectives of Astec Insurance are to improve control over and reduce the cost of claims; to improve focus on risk reduction with the development of a program structure which rewards proactive loss control; and to ensure management participation in the defense and settlement process for claims.

For general liability claims, the captive is liable for the first $1,000 per occurrence and $3,000 per year in the aggregate. The Company carries general liability, excess liability and umbrella policies for claims in excess of amounts covered by the captive.

For workers' compensation claims, the captive is liable for the first $350 per occurrence and $3,250 per year in the aggregate. The Company utilizes a large national insurance company as third-party administrator for workers' compensation claims and carries insurance coverage for claims liabilities in excess of amounts covered by the captive.

The financial statements of the captive are consolidated into the consolidated financial statements of the Company. The short-term and long-term reserves for claims and potential claims related to general liability and workers' compensation under the captive are included in accrued loss reserves or other long-term liabilities, respectively, in the consolidated balance sheets depending on the expected timing of future payments. The undiscounted reserves are actuarially determined to cover the ultimate cost of each claim based on the Company's evaluation of the type and severity of individual claims and historical information, primarily its own claims experience, along with assumptions about future events. Changes in assumptions, as well as changes in actual experience, could cause these estimates to change in the future. However, the Company does not believe it is reasonably likely that the reserve level will materially change in the foreseeable future.

The Company is self-insured for health and prescription claims under its Group Health Insurance Plan at all but one of the Company's domestic manufacturing subsidiaries. The Company carries reinsurance coverage to limit its exposure for individual health claims above certain limits. Third parties administer health claims and prescription medication claims. The Company maintains a reserve for the self-insured health plan which is included in accrued loss reserves on the Company's consolidated balance sheets. This reserve includes both unpaid claims and an estimate of claims incurred but not reported, based on historical claims and payment experience. Historically, the reserves have been sufficient to provide for claims payments. Changes in actual claims experience or payment patterns could cause the reserve to change, but the Company does not believe it is reasonably likely that the reserve level will materially change in the near future.

The remaining U.S. subsidiary is covered under a fully insured group health plan. Employees of the Company's foreign subsidiaries are insured under separate health plans. No reserves are necessary for these fully-insured health plans.

Revenue Recognition - Revenue is generally recognized on sales at the point in time when persuasive evidence of an arrangement exists, the price is fixed or determinable, the product has been delivered or services have been rendered and there is a reasonable assurance of collection of the sales proceeds. The Company generally obtains purchase authorizations from its customers for a specified amount of products at a specified price with specified delivery terms. A significant portion of the Company's equipment sales represents equipment produced in the Company's plants under short-term contracts for a specific customer project or equipment designed to meet a customer's specific requirements. Most of the equipment sold by the Company is based on standard configurations, some of which are modified to meet customer needs or specifications. The Company provides customers with technical design and performance specifications and performs pre-shipment testing to ensure the equipment performs according to design specifications, regardless of whether the Company provides installation services in addition to selling the equipment.

Certain contracts include terms and conditions pursuant to which the Company recognizes revenues upon completion of equipment production, which is subsequently stored at the Company's plant at the customer's request. Revenue is recorded on such contracts upon the customer's assumption of title and risk of ownership and when collectability is reasonably assured. In addition, there must be a fixed schedule of delivery of the goods consistent with the customer's business practices, the Company must not have retained any specific performance obligations such that the earnings process is not complete and the goods must have been segregated from the Company's inventory prior to revenue recognition.

The Company has certain sales accounted for as multiple-element arrangements, whereby revenue attributable to the sale of a product is recognized when the product is shipped, and the revenue attributable to services provided with respect to the product (such as installation services) is recognized when the service is performed. Consideration is allocated to deliverables using the relative selling price method using vendor specific objective evidence, if it exists. Otherwise, the Company uses third-party evidence of selling price or the Company's best estimate of the selling price for the deliverables. The Company evaluates sales with multiple deliverable elements (such as an agreement to deliver equipment and related installation services) to determine whether revenue related to individual elements should be recognized separately, or as a combined unit. In addition to the previously mentioned general revenue recognition criteria, the Company only recognizes revenue on individual delivered elements when there is objective and reliable evidence that the delivered element has a determinable value to the customer on a standalone basis and there is no right of return.

The Company has certain sales accounted for under the percentage of completion method using the ratio of costs incurred to estimated total costs. Revenue, in an amount equal to cost incurred, is recognized until there is sufficient information to determine the estimated profit on the project with a reasonable level of certainty. The factors considered in this evaluation include the stage of design completion, the stage of equipment manufacturing completion, the state of construction completion, the status of outstanding subcontracts, certainty of quantities of labor and materials, certainty of schedule and the relationship with the customer.

The Company presents in the consolidated statements of income any taxes assessed by a governmental authority that are directly imposed on revenue-producing transactions between the Company and its customers, such as sales, use, value-added and some excise taxes, on a net (excluded from revenue) basis.

Advertising Expense - The cost of advertising is expensed as incurred. The Company incurred $3,793, $4,045, and $4,231 in advertising costs during 2017, 2016 and 2015, respectively, which is included in selling, general and administrative expenses.

A-36

Income Taxes - Income taxes are based on pre-tax financial accounting income. Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax bases of assets and liabilities and their reported amounts. The Company periodically assesses the need to establish valuation allowances against its deferred tax assets to the extent the Company no longer believes it is more likely than not that the tax assets will be fully utilized.

The Company evaluates a tax position to determine whether it is more likely than not that the tax position will be sustained upon examination, based upon the technical merits of the position. A tax position that meets the more-likely-than-not recognition threshold is subject to a measurement assessment to determine the amount of benefit to recognize and the appropriate reserve to establish, if any. If a tax position does not meet the more-likely-than-not recognition threshold, no benefit is recognized. The Company is periodically audited by U.S. federal and state as well as foreign tax authorities. While it is often difficult to predict final outcome or timing of resolution of any particular tax matter, the Company believes its reserve for uncertain tax positions is adequate to reduce the uncertain positions to the greatest amount of benefit that is more likely than not realizable.

Product Warranty Reserve - The Company accrues for the estimated cost of product warranties at the time revenue is recognized. Warranty obligations by product line or model are evaluated based on historical warranty claims experience. For equipment, the Company's standard product warranty terms generally include post-sales support and repairs of products at no additional charge for periods ranging from three months to two years or up to a specified number of hours of operation. For parts from component suppliers, the Company relies on the original manufacturer's warranty that accompanies those parts. Generally, Company fabricated parts are not covered by specific warranty terms. Although failure of fabricated parts due to material or workmanship is rare, if it occurs, the Company's policy is to replace fabricated parts at no additional charge.

The Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of our component suppliers. Estimated warranty obligations are based upon warranty terms, product failure rates, repair costs and current period machine shipments. If actual product failure rates, repair costs, service delivery costs or post-sales support costs differ from our estimates, revisions to the estimated warranty liability may be required.

Pension and Retirement Plans - The determination of obligations and expenses under the Company's pension plan is dependent on the Company's selection of certain assumptions used by independent actuaries in calculating such amounts. Those assumptions are described in Note 12, Pension and Retirement Plans and include among others, the discount rate, expected return on plan assets and the expected mortality rates. In accordance with U.S. generally accepted accounting principles, actual results that differ from assumptions are accumulated and amortized over future periods and, therefore, generally affect the recognized expense in such periods. Significant differences in actual experience or significant changes in the assumptions used may materially affect the pension obligations and future expenses.

The Company recognizes the overfunded or underfunded status of its pension plan as an asset or liability. Actuarial gains and losses, amortization of prior service cost (credit) and amortization of transition obligations are recognized through other comprehensive income (loss) in the year in which the changes occur. The Company measures the funded status of its pension plan as of the date of the Company's fiscal year-end.

Stock-based Compensation -The Company recognizes the cost of employee services received in exchange for equity awards in the consolidated financial statements based on the grant date calculated fair value of the awards. The Company recognizes stock-based compensation expense over the period during which an employee is required to provide service in exchange for the award (the vesting period). The Company's equity awards are further described in Note 16, Shareholders' Equity.

Earnings Per Share -Basic earnings per share is based on the weighted average number of common shares outstanding and diluted earnings per share includes potential dilutive effects of restricted stock units and shares held in the Company's supplemental executive retirement plan.

A-37

The following table sets forth a reconciliation of the number of shares used in the computation of basic and diluted earnings per share:

	Year Ended December 31
	2017		2016		2015
Denominator:
Denominator for basic earnings per share		23,025		22,992		22,934
Effect of dilutive securities:
Restricted stock units		96		85		123
Supplemental executive retirement plan		63		65		63
Denominator for diluted earnings per share		23,184		23,142		23,120

Derivatives and Hedging Activities - The Company recognizes all derivatives in the consolidated balance sheets at their fair value. Derivatives that are not hedges are adjusted to fair value through income. If the derivative is a hedge, depending on the nature of the hedge, changes in the fair value of derivatives are either offset against the change in fair value of assets, liabilities, or firm commitments through income or recognized in other comprehensive income until the hedged item is recognized in income. The ineffective portion of a derivative's change in fair value is immediately recognized in income. From time to time, the Company's foreign subsidiaries enter into foreign currency exchange contracts to mitigate exposure to fluctuation in currency exchange rates. See Note 13, Derivative Financial Instruments, regarding foreign exchange contracts outstanding at December 31, 2017 and 2016.

Shipping and Handling Fees and Cost - The Company records revenues earned for shipping and handling as revenue, while the cost of shipping and handling is classified as cost of sales.

Business Combinations - The Company accounts for business combinations using the acquisition method. Accordingly, intangible assets are recorded apart from goodwill if they arise from contractual or legal rights or if they are separable from goodwill. Related third-party acquisition costs are expensed as incurred and contingent consideration is booked at its fair value as part of the purchase price. See Note 20, Business Combinations, regarding acquisitions completed by the Company in the years ended December 31, 2017 and 2016.

Subsequent Events Review - Management has evaluated events occurring between December 31, 2017 and the date these consolidated financial statements were filed with the Securities and Exchange Commission for proper recording or disclosure therein.

Recent Accounting Pronouncements -In May 2014, the Financial Accounting Standards Board ('FASB") issued Accounting Standards Update ("ASU") No. 2014-09, "Revenue from Contracts with Customers", which supersedes existing revenue guidance under U.S. GAAP. The standard's core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The implementation of this new standard will require companies to use more judgment and to make more estimates than under current guidance and to expand their disclosures to include information regarding contract assets and liabilities as well as a more disaggregated view of revenue. The standard, as amended, is effective for public companies for annual periods beginning after December 15, 2017. The Company adopted the new standard effective January 1, 2018 using the modified retrospective transition method and will expand its disclosures in the first quarter 2018 consolidated financial statements to comply with the disclosure provisions of the new rule. The Company does not expect the adoption of the standard to have a material impact on its financial position, results of operations or cash flows.

In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments - Overall (Subtopic 825-10)", which requires, among other things, equity investments with readily determinable fair values, except those accounted for under the equity method of accounting or those that result in consolidation of the investee, to be measured at fair value with changes in fair value recognized in net income. The standard is effective for public companies in fiscal years beginning after December 15, 2017, and the Company adopted the standard effective January 1, 2018. The Company does not expect the adoption of this standard to have a material impact on the Company's financial position, cash flows or results of operations.

A-38

In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)", which significantly changes the accounting for operating leases by lessees. The accounting applied by lessors is largely unchanged from that applied under previous guidance. The new guidance requires lessees to recognize lease assets and lease liabilities in the balance sheet, initially measured at the present value of the lease payments, for leases which were classified as operating leases under previous guidance. Lease cost included in the statement of income will be calculated so that the cost of the lease is allocated over the lease term, generally on a straight-line basis. Lessees may make an accounting policy election to exclude leases with a term of 12 months or less from the requirement to record related assets and liabilities. The new standard is effective for public companies for fiscal years beginning after December 15, 2018. The Company plans to adopt the new standard effective January 1, 2019. The Company does not expect the adoption of this standard to have a material impact on its results of operations or cash flows; however, the Company has not determined the impact the adoption of this new standard will have on its financial position.

In March 2016, the FASB issued ASU No. 2016-08, "Revenue from Contracts with Customers (Topic 606)", which does not change the core principles of ASU No. 2014-09 discussed above, but rather clarifies the implementation guidance in order to eliminate the potential for diversity in practice arising from inconsistent application of the principal versus agent guidance. Under the new guidance, when an entity determines it is a principal in a transaction, the entity recognizes revenue in the gross amount of consideration; however, in transactions where an entity determines it is an agent, the entity recognizes revenue in the amount of any fee or commission to which it expects to be entitled. The standard is effective for public companies for annual periods beginning after December 15, 2017. The Company adopted the new standard effective January 1, 2018. The Company does not expect the adoption of this new standard to have a material impact on the Company's financial position, results of operations or cash flows.

In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments". The standard changes how credit losses are measured for most financial assets and certain other instruments that currently are not measured through net income. The standard will require an expected loss model for instruments measured at amortized cost as opposed to the current incurred loss approach. In valuing available for sale debt securities, allowances will be required to be recorded, rather than the current approach of reducing the carrying amount, for other than temporary impairments. A cumulative adjustment to retained earnings is to be recorded as of the beginning of the period of adoption to reflect the impact of applying the provisions of the standard. The standard is effective for public companies for periods beginning after December 15, 2019 and the Company expects to adopt the new standard as of January 1, 2020. The Company has not yet determined what impact, if any, the adoption of this new standard will have on the Company's financial position results of operations or cash flows.

In August 2016, the FASB issued ASU No. 2016-15, "Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force)" which clarifies how certain cash receipts and cash payments should be presented on the statement of cash flows. The statement also addresses how the predominance principle should be applied when cash payments have aspects of more than one class of cash flows. The standard is effective for public companies in fiscal years beginning after December 15, 2017, and the Company adopted the standard effective January 1, 2018. The Company does not expect the adoption of this new standard to have a material impact on the Company's consolidated statements of cash flows.

In October 2016, the FASB issued ASU No. 2016-16, "Income Taxes (Topic 740), Intra-Entity Transfers of Assets Other Than Inventory" which requires companies to account for the income tax effects of intercompany sales and transfers of assets other than inventory, such as intangible assets, when the transfer occurs. This is a change from current guidance, which requires companies to defer the income tax effects of intercompany transfers of assets until the asset has been sold to an outside party or otherwise recognized by being depreciated, amortized, or impaired. The new guidance will require companies to defer the income tax effects of only intercompany transfers of inventory. The standard is effective for public companies in fiscal years beginning after December 15, 2017. The Company adopted the new standard effective January 1, 2018. The Company does not expect the application of this standard to have a material impact on the Company's financial position, results of operations or cash flows.

In January 2017, the FASB issued ASU No. 2017-01, "Business Combinations (Topic 805), Clarifying the Definition of a Business," which provides additional guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The standard is effective for public companies for annual or interim periods beginning after December 15, 2017. The Company adopted the new standard effective January 1, 2018. The Company does not expect the application of this standard to have a material impact on its financial position, results of operations or cash flows.

A-39

In January 2017, the FASB issued ASU No. 2017-04, "Intangibles-Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment," which eliminates Step 2 from the goodwill impairment test for public companies.  Previously, Step 2 measured a goodwill impairment loss by comparing the implied fair value of a reporting unit's goodwill with the carrying amount of that goodwill. The new guidance stipulates that an entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge would be recognized for the amount by which the carrying amount exceeds the reporting unit's fair value, up to the amount of goodwill allocated to the reporting unit. The standard is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019 with early adoption permitted. The Company elected to adopt this standard as of December 31, 2017. The application of this standard did not have a material impact on the Company's financial position, results of operations or cash flows.

In August 2017, the FASB issued ASU No. 2017-12, "Derivatives and Hedging (Topic 815), Targeted Improvements to Hedging Activities", to improve the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements. The new guidance is effective for public companies for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years with early adoption permitted in any interim period after its issuance. The Company plans to adopt the new standard effective January 1, 2019. The Company does not expect the application of this standard to have a material impact on its financial position, results of operations or cash flows.

Used equipment		21,223		22,130
Total	$	391,379	$	360,404

3. Fair Value Measurements

The Company has various financial instruments that must be measured at fair value on a recurring basis, including marketable debt and equity securities held by Astec Insurance, and marketable equity securities held in an unqualified Supplemental Executive Retirement Plan ("SERP"). The financial assets held in the SERP also constitute a liability of the Company for financial reporting purposes. The Company's subsidiaries also occasionally enter into foreign currency exchange contracts to mitigate exposure to fluctuations in currency exchange rates.

For cash and cash equivalents, trade receivables, other receivables, revolving debt and accounts payable, the carrying amount approximates the fair value because of the short-term nature of these instruments. Investments are carried at their fair value based on quoted market prices for identical or similar assets or, where no quoted prices exist, other observable inputs for the asset. The fair values of foreign currency exchange contracts are based on quotations from various banks for similar instruments using models with market based inputs.

A-40

As indicated in the tables below, the Company has determined that its financial assets and liabilities at December 31, 2017 and 2016 are level 1 and level 2 in the fair value hierarchy:

4. Investments

The Company's trading securities consist of the following:

	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses		Fair Value (Net Carrying Amount)
December 31, 2017
Trading equity securities	$	4,964	$	394	$	31	$	5,327
Trading debt securities		10,971		58		179		10,850
Total	$	15,935	$	452	$	210	$	16,177

Trading equity securities	$	3,980	$	40	$	118	$	3,902
Trading debt securities		11,312		23		248		11,087
Total	$	15,292	$	63	$	366	$	14,989

Trading equity investments are valued at their estimated fair value based on their quoted market prices and trading debt securities are valued based upon a mix of observable market prices and model driven prices derived from a matrix of observable market prices for assets with similar characteristics obtained from a nationally recognized third-party pricing service. Additionally, a significant portion of the trading equity securities are in equity money market and mutual funds and also comprise a portion of the Company's liability under its SERP. See Note 12, Pension and Retirement Plans, for additional information on these investments and the SERP.

Trading debt securities are comprised mainly of marketable debt securities held by Astec Insurance. Astec Insurance has an investment strategy that focuses on providing regular and predictable interest income from a diversified portfolio of high-quality fixed income securities.

Net unrealized gains or losses incurred on investments still held as of the end of each reporting period amounted to losses of $319, $107 and $429 in 2017, 2016 and 2015, respectively.

5. Goodwill

Goodwill represents the excess of the purchase price over the fair value of identifiable net assets acquired in business combinations. Current U.S. accounting guidance provides that goodwill and indefinite-lived intangible assets be tested for impairment at least annually. The Company performs the required valuation procedures each year as of December 31 after the following year's forecasts are submitted and reviewed. The valuations performed in 2017, 2016 and 2015 indicated no impairment of goodwill.

The changes in the carrying amount of goodwill by reporting segment during the years ended December 31, 2017 and 2016 are as follows:

	Infrastructure Group			Aggregate and Mining Group			Energy Group		Total
Balance, December 31, 2015	$	8,481		$	22,354		$	--	$	30,835
Acquisition		--			--			12,632		12,632

9. Debt

On April 12, 2017, the Company and certain of its subsidiaries entered into an amended and restated credit agreement whereby the lender extended to the Company an unsecured line of credit of up to $100,000, including a sub-limit for letters of credit of up to $30,000. There were no outstanding revolving or term loan borrowings under the credit facility at December 31, 2017 or 2016. Letters of credit totaling $9,757, including $3,200 of letters of credit issued to banks in Brazil to secure the local debt of Astec do Brasil Fabricacao de Equipamentos Ltda. ("Astec Brazil"), were outstanding under the credit facility as of December 31, 2017, resulting in additional borrowing ability of $90,243 under the credit facility. The credit agreement has a five-year term expiring in April 2022. Borrowings under the agreement are subject to an interest rate equal to the daily one-month LIBOR rate plus a 0.75% margin, resulting in a rate of 2.32% as of December 31, 2017. The unused facility fee is 0.125%. Interest only payments are due monthly. The amended and restated credit agreement contains certain financial covenants, including provisions concerning required levels of annual net income and minimum tangible net worth.

The Company's South African subsidiary, Osborn Engineered Products SA (Pty) Ltd ("Osborn"), has a credit facility of $7,672 with a South African bank to finance short-term working capital needs, as well as to cover performance letters of credit, advance payment and retention guarantees. As of December 31, 2017, Osborn had no outstanding borrowings but had $813 in performance, advance payment and retention guarantees outstanding under the facility. The facility has been guaranteed by Astec Industries, Inc., but is otherwise unsecured. A 0.75% unused facility fee is charged if less than 50% of the facility is utilized. As of December 31, 2017, Osborn had available credit under the facility of $6,859. The interest rate is 0.25% less than the South Africa prime rate, resulting in a rate of 10.0% as of December 31, 2017.

The Company's Brazilian subsidiary has outstanding working capital loans totaling $3,402 from Brazilian banks with interest rates ranging from 10.4% to 11.0%. The loans' maturity dates ranging from November 2018 to April 2024 and are secured by Astec Brazil's manufacturing facility and also by letters of credit totaling $3,200 issued by Astec Industries, Inc. Additionally, Astec Brazil has various five-year equipment financing loans outstanding with Brazilian banks in the aggregate of $642 as of December 31, 2017 that have interest rates ranging from 3.5% to 16.3%. These equipment loans have maturity dates ranging from September 2018 to April 2020. Astec Brazil's loans are included in the accompanying consolidated balance sheets as current maturities of long-term debt of $2,469 and long-term debt of $1,575 as of December 31, 2017.

Long-term debt maturities are expected to be $2,469, $729, $251, $251 and $251 in the years ending December 31, 2018, 2019, 2020, 2021 and 2022, respectively, and $93 thereafter.

10. Product Warranty Reserves

The Company warrants its products against manufacturing defects and performance to specified standards. The warranty period and performance standards vary by product, but generally range from three months to two years or up to a specified number of hours of operation. The Company estimates the costs that may be incurred under its warranties and records a liability at the time product sales are recorded. The warranty liability is primarily based on historical claim rates, nature of claims and the associated costs.

Changes in the Company's product warranty liability during 2017, 2016 and 2015 are as follows:

	2017			2016			2015
Reserve balance, beginning of year	$	13,156		$	9,100		$	10,032
Warranty liabilities accrued		16,725			18,912			13,743
Warranty liabilities settled		(14,642	)		(15,125	)		(14,177	)
Other		171			269			(498	)
Reserve balance, end of year	$	15,410		$	13,156		$	9,100

A-44

11. Accrued Loss Reserves

The Company accrues reserves for losses related to known workers' compensation and general liability claims that have been incurred but not yet paid or are estimated to have been incurred but not yet reported to the Company. The undiscounted reserves are actuarially determined based on the Company's evaluation of the type and severity of individual claims and historical information, primarily its own claim experience, along with assumptions about future events. Changes in assumptions, as well as changes in actual experience, could cause these estimates to change in the future. Total accrued loss reserves at December 31, 2017 were $8,119 and $7,892 at December 31, 2016, of which $5,615 and $5,040 were included in other long-term liabilities at December 31, 2017 and 2016, respectively.

12. Pension and Retirement Plans

Prior to December 31, 2003, all employees of the Company's Kolberg-Pioneer, Inc. subsidiary were covered by a defined benefit pension plan. After December 31, 2003, all benefit accruals under the plan ceased and no new employees could become participants in the plan. Benefits paid under this plan are based on years of service multiplied by a monthly amount. The Company's funding policy for the plan is to make at least the minimum annual contributions required by applicable regulations.

The Company's investment strategy for the plan is to earn a rate of return sufficient to match or exceed the long-term growth of pension liabilities. The investment policy states that the Plan Committee in its sole discretion shall determine the allocation of plan assets among the following four asset classes: cash equivalents, fixed-income securities, domestic equities and international equities. The Plan Committee attempts to ensure adequate diversification of the invested assets through investment in an exchange traded mutual fund that invests in a diversified portfolio of stocks, bonds and money market securities.

The following provides information regarding benefit obligations, plan assets and the funded status of the plan:

	Pension Benefits

A-45

The measurement date used for the plan was December 31. In determining the expected return on plan assets, the historical experience of the plan assets, the current and expected allocation of the plan assets and the expected long-term rates of return were considered.

All assets in the plan are invested in an exchange traded mutual fund (level 1 in the fair value hierarchy). The allocation of assets within the mutual fund as of December 31 and the target asset allocation ranges by asset category are as follows:

Asset Category	Actual Allocation 2017			Actual Allocation 2016			2017 & 2016 Target Allocation Ranges
Equity securities		49.4	%		63.6	%		40 - 65	%
Debt securities		43.2	%		33.5	%		30 - 50	%
Cash and Equivalents		7.4	%		2.9	%		0 - 15	%
Total		100.0	%		100.0	%

Net periodic benefit cost for 2017, 2016 and 2015 included the following components:

	Pension Benefits
	2017			2016			2015
Components of net periodic benefit cost
Interest cost	$	630		$	650		$	596
Expected return on plan assets		(720	)		(782	)		(840	)

Discount rate		4.00	%		4.28	%		3.81	%
Expected return on plan assets		6.25	%		7.00	%		7.00	%

No contributions are expected to be funded by the Company during 2018.

Amounts in accumulated other comprehensive loss expected to be recognized in net periodic benefit cost in 2018 for the amortization of a net loss is $466.

The following estimated future benefit payments are expected in the years indicated:

	Pension Benefits

A-46

The Company sponsors a 401(k) defined contribution plan to provide eligible employees with additional income upon retirement. The Company's contributions to the plan are based on employee contributions. The Company's contributions totaled $7,182, $5,943 and $5,292 in 2017, 2016 and 2015, respectively.

The Company maintains a SERP for certain of its executive officers. The plan is a non-qualified deferred compensation plan administered by the Board of Directors of the Company, pursuant to which the Company makes quarterly cash contributions of a certain percentage of executive officers' compensation. Investments are self-directed by participants and can include Company stock. Upon retirement, participants receive their apportioned share of the plan assets in the form of cash.

Assets of the SERP consist of the following:

	December 31, 2017						December 31, 2016
	Cost			Market			Cost			Market
Company stock		$	1,960		$	3,589		$	1,958		$	4,455
Equity securities			4,589			4,963			3,474			3,427
Total		$	6,549		$	8,552		$	5,432		$	7,882

The Company periodically adjusts the deferred compensation liability such that the balance of the liability equals the total fair market value of all assets held by the trust established under the SERP. Such liabilities are included in other long-term liabilities on the consolidated balance sheets. The equity securities are included in investments in the consolidated balance sheets and classified as trading equity securities. See Note 4, Investments, for additional information. The cost of the Company stock held by the plan is included as a reduction in shareholders' equity in the consolidated balance sheets.

The change in the fair market value of Company stock held in the SERP results in a charge or credit to selling, general and administrative expenses in the consolidated statements of income because the acquisition cost of the Company stock in the SERP is recorded as a reduction of shareholders' equity and is not adjusted to fair market value; however, the related liability is adjusted to the fair market value of the stock as of each period end. The Company recognized income of $575 in 2017 and expense of $1,742 and $241 in 2016 and 2015, respectively, related to the change in the fair value of the Company stock held in the SERP.

13. Derivative Financial Instruments

The Company is exposed to certain risks relating to its ongoing business operations. The primary risk managed by using derivative instruments is foreign currency risk. From time to time, the Company's foreign subsidiaries enter into foreign currency exchange contracts to mitigate exposure to fluctuations in currency exchange rates. The fair value of the derivative financial instrument is recorded on the Company's consolidated balance sheets and is adjusted to fair value at each measurement date. The changes in fair value are recognized in the consolidated statements of income in the current period. The Company does not engage in speculative transactions nor does it hold or issue derivative financial instruments for trading purposes. The average U.S. dollar equivalent notional amount of outstanding foreign currency exchange contracts was $11,099 during 2017. At December 31, 2017, the Company reported $112 of derivative liabilities in other current liabilities. The Company reported $144 of derivative assets in other current assets and $89 of derivative liabilities in other current liabilities at December 31, 2016. The Company recognized, as a component of cost of sales, a net loss on the change in fair value of derivative instruments of $663 and $336 for the years ended December 31, 2017 and 2016, respectively. The Company recognized a net gain on the change in fair value of derivative instruments of $606 for the year ended December 31, 2015. There were no derivatives that were designated as hedges at December 31, 2017 or 2016.

14. Income Taxes

For financial reporting purposes, income before income taxes includes the following components:

	Year Ended December 31
	2017			2016				2015
United States		$	55,980		$	87,326			$	57,846
Foreign			1,237			(231	)			(5,873	)
Income before income taxes		$	57,217		$	87,095			$	51,973

The provision for income taxes consists of the following:

	Year Ended December 31
	2017			2016			2015
Current provision:
Federal	$	16,178		$	30,623		$	19,758

Foreign		931			1,252			(846	)
Total income tax provision	$	19,627		$	32,107		$	20,007

The Company's income tax provision is computed based on the domestic and foreign federal statutory rates and the average state statutory rates, net of related federal benefit.

The provision for income taxes differs from the amount computed by applying the statutory federal income tax rate to income before income taxes. A reconciliation of the provision for income taxes at the statutory federal income tax rate to the amount provided is as follows:

	Year Ended December 31
	2017			2016			2015
Tax at the statutory federal income tax rate	$	20,026		$	30,483		$	18,191
Qualified production activity deduction		(1,661	)		(1,641	)		(1,174	)

U.S. Tax Reform impact		(1,056	)		--			--
Other items		(483	)		(137	)		(534	)
Total income tax provision	$	19,627		$	32,107		$	20,007

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

Significant components of the Company's deferred tax assets and liabilities are as follows:

	December 31
	2017			2016
Deferred tax assets:
Inventory reserves	$	4,287		$	8,507
Warranty reserves		3,560			4,527

Outside basis differences		--			511
Total deferred tax liabilities		16,743			24,732
Total net deferred assets	$	1,067		$	1,007

As of December 31, 2017, the Company has state net operating loss carryforwards of $17,579 and foreign net operating loss carryforwards of approximately $19,876, which will be available to offset future taxable income. If not used, these carryforwards will expire between 2018 and 2030. A significant portion of the valuation allowance for deferred tax assets relates to the future utilization of state and foreign net operating loss and state tax credit carryforwards. Future utilization of these net operating loss and state tax credit carryforwards is evaluated by the Company on a periodic basis and the valuation allowance is adjusted accordingly. In 2017, the valuation allowance on these carryforwards was increased by $7 due to the uncertainty about whether certain entities will realize their state and foreign net operating loss carryforwards. The Company has also determined that the recovery of certain other deferred tax assets is uncertain. The valuation allowance for these deferred tax assets was increased by $31 during 2017.

The following table represents a roll forward of the deferred tax asset valuation allowance for the years ended December 31, 2017, 2016 and 2015:

	Year Ended December 31
	2017			2016			2015
Allowance balance, beginning of year	$	8,280		$	8,065		$	6,029
Provision		1,585			1,639			2,036
Write-offs		(1,862	)		(289	)		--

Undistributed earnings of the Company's Canadian subsidiary, Breaker Technology Ltd. ("BTL") and South African subsidiary, Osborn Engineered Products SA, (PTY), Ltd. ("Osborn") are considered to be indefinitely reinvested; accordingly, no provision for U.S. federal and state income taxes has been provided thereon. As of December 31, 2017, the cumulative amounts of undistributed GAAP earnings for BTL and Osborn are $4,026 and $28,249, respectively. A portion of these amounts may be subject to taxation under the one-time transition tax included in the Tax Cuts and Jobs Act of 2017. Based upon the provisions in the Tax Cuts and Jobs Act of 2017, any future qualified dividends out of these amounts will not be subject to U.S. income taxes. However, upon any future inclusion as Subpart F income or capital gains, the Company would be subject to additional U.S. income taxes (subject to an adjustment for foreign tax credits). Upon any repatriation, withholding taxes due to the foreign jurisdictions may have to be paid. At this time, it is not practicable to determine the amount of the unrecognized deferred tax liability for temporary differences related to investments in foreign subsidiaries.

The Company files income tax returns in the U.S. federal jurisdiction, and in various state and foreign jurisdictions. The Company is no longer subject to U.S. federal income tax examinations by authorities for years prior to 2014. With few exceptions, the Company is no longer subject to state and local or non-U.S. income tax examinations by authorities for years prior to 2012.

The Company has a liability for unrecognized tax benefits of $365 and $238 (excluding accrued interest and penalties) as of December 31, 2017 and 2016, respectively. The Company recognizes interest and penalties accrued related to unrecognized tax benefits in tax expense. The Company recognized tax benefits of $22 and $16 in 2017 and 2016, respectively, for penalties and interest related to amounts that were settled for less than previously accrued. The net total amount of unrecognized tax benefits that, if recognized, would affect the Company's effective tax rate is $370 and $238 at December 31, 2017 and 2016, respectively. The Company does not expect a significant increase or decrease to the total amount of unrecognized tax benefits within the next twelve months.

A reconciliation of the beginning and ending unrecognized tax benefits excluding interest and penalties is as follows:

	Year Ended December 31
	2017		2016			2015
Balance, beginning of year	$	238	$	603		$	2,585
Additions for tax positions related to the current year		127		73			206
Additions for tax positions related to prior years		--		162			549
Reductions due to lapse of statutes of limitations		--		(16	)		(162	)
Decreases related to settlements with tax authorities		--		(584	)		(2,575	)
Balance, end of year	$	365	$	238		$	603

The December 31, 2017 balance of unrecognized tax benefits includes no tax positions for which the ultimate deductibility is highly certain but the timing of such deductibility is uncertain. Accordingly, there is no impact to the deferred tax accounting for certain tax benefits.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the "Tax Act") was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a federal corporate tax rate decrease from 35% to 21% for tax years beginning after December 31, 2017, the transition of U.S international taxation from a worldwide tax system to a territorial system and a one-time transition tax on the mandatory deemed repatriation of foreign earnings. The Company's fourth quarter 2017 provision for income taxes was reduced by $1,056, (comprised of a $1,548 reduction in income tax expense recorded in connection with the remeasurement of deferred tax assets and liabilities and $492 of additional income tax expense recorded in connection with the transition tax on the mandatory deemed repatriation of foreign earnings) due to applying the provisions of the Tax Act.

A-50

On December 22, 2017, Staff Accounting Bulletin No. 118 ("SAB 118") was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Act. In accordance with SAB 118, the Company determined that the $492 additional 2017 income tax expense is a provisional amount and constitutes a reasonable estimate at December 31, 2017, based upon the best information currently available. The ultimate impact may differ from the provisional amount, possibly materially, due to, among other things, additional analysis, changes in interpretations and assumptions the Company has made, additional regulatory guidance that may be issued and actions the Company may take as a result of the Tax Act. Any subsequent adjustment to the amount will be recorded to current income tax expense when the analysis is complete, which is expected in 2018 shortly after the filing of the Company's 2017 U.S. income tax return.

While the Tax 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 the Company to include, in its U.S. income tax return, foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary's tangible assets. The Company has elected to account for GILTI tax in the period in which it is incurred, and therefore, has not provided any deferred tax impacts of GILTI in its consolidated financial statements for the year ended December 31, 2017.

The BEAT provisions in the Tax Act eliminates the deduction of certain base-erosion payments made to related foreign corporations, and impose a minimum tax, if greater than regular tax. The Company does not expect it will be subject to this tax, and therefore, has not included any tax impacts of BEAT in its consolidated financial statements for the year ended December 31, 2017.

The changes to existing U.S. tax laws as a result of the Tax Act, which we believe have the most significant impact on the Company's federal income taxes are as follows:

Reduction of the U.S. Corporate Income Tax Rate: The Company measures deferred tax assets and liabilities using enacted tax rates that will apply in the years in which the temporary differences are expected to be recovered or paid. Accordingly, the Company recognized a deferred tax benefit and related increase in deferred tax assets of $1,548 in its 2017 consolidated financial statements due to the remeasurement necessitated by the Tax Act's provision reducing the reduction in the U.S. corporate income tax rate from 35% to 21%. This benefit is attributable to the Company being in a net deferred tax liability position when considering only U.S. federal deferred items. The Company has significant deferred tax assets related to foreign jurisdictions and U.S. state income taxes.

Transition Tax on Foreign Earnings: The Company recognized a provisional income tax expense of $492 for the year ended December 31, 2017 related to the one-time transition tax on certain foreign earnings. The determination of the transition tax requires further analysis regarding the amount and composition of the Company's historical foreign earnings and foreign taxes, which is expected to be completed in 2018.

Repeal of Domestic Production Activities Deduction: While not effective until 2018, the Tax Act repeals the Domestic Production Activities Deduction ("DPAD") previously provided under IRC §199. The DPAD benefit has historically been very material to the Company's federal income taxes. The DPAD benefits included in the effective tax rate reconciliations for 2017, 2016 and 2015 were $1,661, $1,641 and $1,174, respectively.

15. Contingent Matters

Certain customers have financed purchases of Company products through arrangements in which the Company is contingently liable for customer debt of $3,805 at December 31, 2017. These arrangements expire at various dates through December 2020 and provide that the Company will receive the lender's full security interest in the equipment financed if the Company is required to fulfill its contingent liability under these arrangements. The Company has recorded a liability of $836 related to these guarantees as of December 31, 2017.

In addition, the Company is contingently liable under letters of credit issued by a lender totaling $9,757 as of December 31, 2017, including $3,200 of letters of credit guaranteeing certain Astec Brazil bank debt. The outstanding letters of credit expire at various dates through October 2020. As of December 31, 2017, the Company's foreign subsidiaries are contingently liable for a total of $3,557 in performance letters of credit, advance payments and retention guarantees. The maximum potential amount of future payments under these letters of credit and guarantees for which the Company could be liable is $13,314 as of December 31, 2017.

A-51

The Company has a sales contract with the purchaser of a large wood pellet plant, on which revenues of $7,987 and $135,187 were recorded in 2017 and 2016, respectively. As the plant has not yet met the production output and the operational specifications set forth in the original contract, as amended through December 31, 2017, the Company entered into a contract amendment in February 2018, whereby the Company agreed to compensate the customer for production shortfalls caused by the Company and other potential costs (depending upon the market price of wood pellets), from January 1, 2018 through June 15, 2018. The Company incurred production shortfalls in January and February 2018.

The Company is currently a party to various claims and legal proceedings that have arisen in the ordinary course of business. If management believes that a loss arising from such claims and legal proceedings is probable and can reasonably be estimated, the Company records the amount of the loss (excluding estimated legal fees) or the minimum estimated liability when the loss is estimated using a range and no point within the range is more probable than another. As management becomes aware of additional information concerning such contingencies, any potential liability related to these matters is assessed and the estimates are revised, if necessary. If management believes that a loss arising from such claims and legal proceedings is either (i) probable but cannot be reasonably estimated or (ii) reasonably possible but not probable, the Company does not record the amount of the loss, but does make specific disclosure of such matter. Based upon currently available information and with the advice of counsel, management believes that the ultimate outcome of its current claims and legal proceedings, individually and in the aggregate, will not have a material adverse effect on the Company's financial position, cash flows or results of operations. However, claims and legal proceedings are subject to inherent uncertainties and rulings unfavorable to the Company could occur. If an unfavorable ruling were to occur, there exists the possibility of a material adverse effect on the Company's financial position, cash flows or results of operations.

16. Shareholders' Equity

The Company rewards key members of management with restricted stock units ("RSUs") each year based upon the financial performance of the Company and its subsidiaries. Under the terms of the Company's shareholder-approved 2011 Incentive Plan, up to 700 shares of newly-issued Company stock is available for awards. Awards granted in 2016 and prior vest at the end of five years from the date of grant, or at the time a recipient retires after reaching age 65, if earlier, while awards granted after 2016 are scheduled to have a three-year vesting period. Additional RSUs are granted to the Company's outside directors under the Company's Non-Employee Directors Compensation Plan with a one-year vesting period. The fair value of the RSUs vested during 2017, 2016 and 2015 was $1,991, $3,289 and $2,785, respectively. The grant date tax benefit was increased by $290, $220 and $336, respectively, upon the vesting of RSUs in 2017, 2016 and 2015.

Compensation expense of $2,978, $2,426 and $1,019 was recorded in the years ended December 31, 2017, 2016 and 2015, respectively, to reflect the fair value of RSUs granted (or anticipated to be granted for 2017 performance) amortized over the portion of the vesting period occurring during the period. Related income tax benefits of $1,132, $934 and $362 were recorded in 2017, 2016 and 2015, respectively. Based upon the grant date fair value of RSUs, it is anticipated that $5,210 of additional compensation costs will be recognized in future periods through 2021 for RSUs earned through December 31, 2017. The weighted average period over which this additional compensation cost will be expensed is 2.6 years. RSUs do not participate in Company-paid dividends.

Changes in restricted stock units during the year ended December 31, 2017 are as follows:

	2017			Weighted AverageGrant Date Fair Value
Unvested restricted stock units, beginning of year		112		$	41.48
Units granted		83			65.20
Units forfeited		(3	)		53.11
Units vested		(31	)		43.51
Unvested restricted stock units, end of year		161			53.09

The grant date fair value of the restricted stock units granted during 2017, 2016 and 2015 was $5,399, $1,946 and $937, respectively.

17. Operations by Industry Segment and Geographic Area

The Company has three reportable segments, each of which is comprised of multiple business units that offer similar products and services and meet the requirements for aggregation. A brief description of each segment is as follows:

Infrastructure Group - This segment consists of five business units, three of which design, engineer, manufacture and market a complete line of portable, stationary and relocatable hot-mix asphalt plants, wood pellet plants, asphalt pavers, material transfer vehicles, soil stabilizing – reclaiming machinery, milling machines, paver screeds and related ancillary equipment. The other two business units in this segment primarily operate as Company-owned dealers in the foreign countries in which they are domiciled. These two business units sell, service and install products produced by the manufacturing subsidiaries of the Company, and a majority of their sales are to customers in the infrastructure industry. The principal purchasers of the products produced by this group are asphalt producers, highway and heavy equipment contractors, wood pellet processors and foreign and domestic governmental agencies. The Infrastructure Group had sales to one pellet plant customer totaling $7,987, or 0.7% of total Company sales in 2017 and $135,187, or 11.8% of total Company sales in 2016. Portions of the equipment sold to this customer were manufactured by each of the Company's segments.

Aggregate and Mining Group - This segment consists of eight business units that design, engineer, manufacture and market a complete line of jaw crushers, cone crushers, horizontal shaft impactors, vertical shaft impactors, material handling, roll rock crushers and stationary rockbreaker systems, vibrating feeders and high frequency vibrating screens, conveyors, inclined, vertical and horizontal screens and sand classifying and washing equipment. The principal purchasers of products produced by this group are distributors, open mine operators, quarry operators, port and inland terminal operators, highway and heavy equipment contractors and foreign and domestic governmental agencies.

Energy Group - This segment consists of six business units that design, engineer, manufacture and market a complete line of drilling rigs for the oil and gas, geothermal and water well industries, high pressure diesel pump trailers for fracking and cleaning oil and gas wells, concrete plants, commercial and industrial burners, combustion control systems, a variety of industrial heaters to fit a broad range of applications including heating equipment for refineries, roofing material plants, chemical processing, rubber plants, oil sands and energy related processing, heat transfer processing equipment, thermal fluid storage tanks, waste heat recovery equipment, whole-tree pulpwood and biomass chippers and horizontal grinders. The principal purchasers of products produced by this group are oil, gas and water well drilling industry contractors, processors of oil, gas and biomass for energy production, ready mix concrete producers and contractors in the construction and demolition recycling markets. This group includes the operations of RexCon, Inc., which was acquired in October 2017.

Corporate - This category consists of business units that do not meet the requirements for separate disclosure as an operating segment or inclusion in one of the other reporting segments and includes the Company's parent company, Astec Industries, Inc., and a captive insurance company. The Company evaluates performance and allocates resources to its operating segments based on profit or loss from operations before U.S. federal income taxes and corporate overhead and thus these costs are included in the Corporate category.

The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies. Intersegment sales and transfers are valued at prices comparable to those for unrelated parties.

20. Business Combinations

In October, 2017, the Company acquired substantially all of the assets and liabilities of RexCon, Inc. ("RexCon") for a total purchase price of $26,443. The purchase price was paid in cash with $3,000 deposited into escrow for a period of time not to exceed 18 months pending final resolution of certain post-closing adjustments and any indemnification claims. The Company's preliminary allocation of the purchase price includes the recognition of $3,488 of goodwill and $7,778 of other intangible assets consisting of non-compete agreements (5-year useful life), technology (19-year useful life), trade names (15-year useful life), and customer relationships (18-year useful life). The revenues and results of operations of RexCon were not significant in relation to the Company's consolidated financial statements for the period ended December 31, 2017 and would not have been material on a proforma basis to any earlier period. RexCon's operating results are included in the Company's Energy Group beginning in the fourth quarter of 2017.

RexCon, located in Burlington, Wisconsin was founded in 2003 through an asset acquisition with the original company founded over 100 years ago.  RexCon is a manufacturer of high-quality stationary and portable, central mix and ready mix concrete batch plants, concrete mixers and concrete paving equipment.

In August 2016, the Company acquired substantially all of the assets and certain liabilities of Power Flame Incorporated ("PFI") for a total purchase price of $39,765. The purchase price was paid in cash with $4,000 deposited into escrow for a period of time not to exceed two years pending final resolution of certain post-closing adjustments and any indemnification claims. The Company's allocation of the purchase price resulted in the recognition of $12,632 of goodwill and $17,990 of other intangible assets consisting of technology (19 year useful life), trade names (15 year useful life) and customer relationships (18 year useful life). The revenues and results of operations of PFI were not significant in relation to the Company's consolidated financial statements for the period ended December 31, 2016 and would not have been material on a proforma basis to any earlier period.

Summary of Significant Accounting Policies [Abstract]

Summary of Significant Accounting Policies

1. Summary of Significant Accounting Policies

Basis of Presentation - The consolidated financial statements include the accounts of Astec Industries, Inc. and its domestic and foreign subsidiaries (the "Company"). The Company's significant wholly-owned and consolidated subsidiaries at December 31, 2017 are as follows:

Astec Australia Pty Ltd	Astec do Brasil Fabricacao de Equipamentos Ltda. (92% owned)
Astec, Inc.	Astec Insurance Company
Astec Mobile Machinery GmbH	Astec Mobile Screens, Inc.
Breaker Technology, Inc.	Breaker Technology Ltd.
Carlson Paving Products, Inc.	CEI Enterprises, Inc.
GEFCO, Inc.	Heatec, Inc.
Johnson Crushers International, Inc.	Kolberg-Pioneer, Inc.
Osborn Engineered Products SA (Pty) Ltd	Peterson Pacific Corp.
(99% owned)	Power Flame Incorporated
RexCon, Inc.	Roadtec, Inc.
Telestack Limited	Telsmith, Inc.

All intercompany accounts and transactions have been eliminated in consolidation. Certain reclassifications have been made to the 2016 consolidated financial statements to conform to the 2017 presentation.

Use of Estimates - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported and disclosed in the financial statements and accompanying notes. Actual results could differ from those estimates.

Foreign Currency Translation - Subsidiaries located in Australia, Brazil, Canada, Germany, Northern Ireland, and South Africa operate primarily using local functional currencies. Accordingly, assets and liabilities of these subsidiaries are translated using exchange rates in effect at the end of the period, and revenues and costs are translated using average exchange rates for the period. The resulting adjustments are presented as a separate component of accumulated other comprehensive loss. Foreign currency transaction gains and losses, net are included in cost of sales and amounted to a gain of $431 in 2017 and losses of $246 and $1,377 in 2016 and 2015, respectively.

Fair Value of Financial Instruments - For cash and cash equivalents, trade receivables, other receivables, revolving debt and accounts payable, the carrying amount approximates the fair value because of the short-term nature of those instruments. Trading equity investments are valued at their estimated fair value based on their quoted market prices and debt securities are valued based upon a mix of observable market prices and model driven prices derived from a matrix of observable market prices for assets with similar characteristics obtained from a nationally recognized third party pricing service.

Financial assets and liabilities are categorized as of the end of each reporting period based upon the level of judgment associated with the inputs used to measure their fair value. The inputs used to measure the fair value are identified in the following hierarchy:

Level 1 -                 Unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 - Unadjusted quoted prices in active markets for similar assets or liabilities; or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active; or inputs other than quoted prices that are observable for the asset or liability.

Level 3 - Inputs reflect management's best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.

All financial assets and liabilities held by the Company at December 31, 2017 and 2016 are classified as Level 1 or Level 2, as summarized in Note 3, Fair Value Measurements.

Cash and Cash Equivalents - All highly liquid investments with an original maturity of three months or less when purchased are considered to be cash and cash equivalents.

Investments - Investments consist primarily of investment-grade marketable securities. Trading securities are carried at fair value, with unrealized holding gains and losses included in net income. Realized gains and losses are accounted for on the specific identification method. Purchases and sales are recorded on a trade date basis. Management determines the appropriate classification of its investments at the time of acquisition and reevaluates such determination at each balance sheet date.

Concentration of Credit Risk - The Company sells products to a wide variety of customers. Accounts receivable are carried at their outstanding principal amounts, less an allowance for doubtful accounts. The Company extends credit to its customers based on an evaluation of the customers' financial condition generally without requiring collateral, although the Company normally requires advance payments or letters of credit on large equipment orders. Credit risk is driven by conditions within the economy and the industry and is principally dependent on each customer's financial condition. To minimize credit risk, the Company monitors credit levels and financial conditions of customers on a continuing basis. After considering historical trends for uncollectible accounts, current economic conditions and specific customer recent payment history and financial stability, the Company records an allowance for doubtful accounts at a level which management believes is sufficient to cover probable credit losses. Amounts are deemed past due when they exceed the payment terms agreed to by the customer in the sales contract. Past due amounts are charged off when reasonable collection efforts have been exhausted and the amounts are deemed uncollectible by management. As of December 31, 2017, concentrations of credit risk with respect to receivables are limited due to the wide variety of customers.

Allowance for Doubtful Accounts - The following table represents a rollforward of the allowance for doubtful accounts for the years ended December 31, 2017, 2016 and 2015:

	Year Ended December 31
	2017			2016			2015
Allowance balance, beginning of year	$	1,511		$	1,837		$	2,248
Provision		482			280			18
Write offs		(308	)		(560	)		(357	)
Other		31			(46	)		(72	)
Allowance balance, end of year	$	1,716		$	1,511		$	1,837

Inventories - The Company's inventory is comprised of raw materials, work-in-process, finished goods and used equipment.

Raw material inventory is comprised of purchased steel and other purchased items for use in the manufacturing process or held for sale for the after-market parts business. The category also includes the manufacturing cost of completed equipment sub-assemblies produced for either integration into equipment manufactured at a later date or for sale in the Company's after-market parts business.

Work-in-process inventory consists of the value of materials, labor and overhead incurred to date in the manufacturing of incomplete equipment or incomplete equipment sub-assemblies being produced.

Finished goods inventory consists of completed equipment manufactured for sale to customers.

Used equipment inventory consists of equipment accepted in trade or purchased on the open market. The category also includes equipment rented to prospective customers on a short-term or month-to-month basis. Used equipment is valued at the lower of acquired or trade-in cost or net realizable value determined on each separate unit. Each unit of rental equipment is valued at the lower of original manufacturing, acquired or trade-in cost or net realizable value.

Inventories are valued at the lower of cost (first-in, first-out) or net realizable value, which requires the Company to make specific estimates, assumptions and judgments in determining the amount, if any, of reductions in the valuation of inventories to their net realizable values. The net realizable values of the Company's products are impacted by a number of factors, including changes in the price of steel, competitive sales pricing, quantities of inventories on hand, the age of the individual inventory items, market acceptance of the Company's products, the Company's normal gross margins, actions by our competitors, the condition of our used and rental inventory and general economic factors. Once an inventory item's value has been deemed to be less than cost, a net realizable value allowance is calculated and a new "cost basis" for that item is effectively established. This new cost is retained for that item until such time as the item is disposed of or the Company determines that an additional write-down is necessary. Additional write-downs may be required in the future based upon changes in assumptions due to general economic downturns in the markets in which the Company operates, changes in competitor pricing, new product design or other technological advances introduced by the Company or its competitors and other factors unique to individual inventory items.

The most significant component of the Company's inventory is steel. A significant decline in the market price of steel could result in a decline in the market value of the equipment or parts we sell. During periods of significant declining steel prices, the Company reviews the valuation of its inventories to determine if reductions are needed in the recorded value of inventory on hand to its net realizable value.

The Company reviews the individual items included in its finished goods, used equipment and rental equipment inventory on a model-by-model or unit-by-unit basis to determine if any item's net realizable value is below its carrying value. This analysis is expanded to include items in work-in-process and raw material inventory if factors indicate those items may also be impacted. In performing this review, judgments are made and, in addition to the factors discussed above, additional consideration is given to the age of the specific items of used or rental inventory, prior sales offers or lack thereof, the physical condition of the specific items and general market conditions for the specific items. Additionally, an analysis of raw material inventory is performed to calculate reserves needed for obsolete inventory based upon quantities of items on hand, the age of those items and their recent and expected future usage or sale.

When the Company determines that the value of inventory has become impaired through damage, deterioration, obsolescence, changes in price levels, excessive levels of inventory or other causes, the Company reduces the carrying value to the net realizable value based on estimates, assumptions and judgments made from the information available at that time. Abnormal amounts of idle facility expense, freight, handling cost and wasted materials are recognized as current period charges.

Property and Equipment - Property and equipment is stated at cost. Depreciation is calculated for financial reporting purposes using the straight-line method based on the estimated useful lives of the assets as follows: airplanes (20 years), buildings (40 years) and equipment (3 to 10 years). Both accelerated and straight-line methods are used for tax compliance purposes. Routine repair and maintenance costs and planned major maintenance are expensed when incurred.

Goodwill and Other Intangible Assets - The Company classifies intangible assets as either intangible assets with definite lives subject to amortization or goodwill.

The Company tests intangible assets with definite lives for impairment if conditions exist that indicate the carrying value may not be recoverable. Such conditions may include an economic downturn in a geographic market or a change in the assessment of future operations. An impairment charge is recorded when the carrying value of the definite lived intangible asset is not recoverable by the future undiscounted cash flows expected to be generated from the use of the asset.

The Company determines the useful lives of identifiable intangible assets after considering the specific facts and circumstances related to each intangible asset. Factors considered when determining useful lives include the contractual terms of agreements, the history of the asset, the Company's long-term strategy for the use of the asset, any laws or other local regulations which could impact the useful life of the asset, and other economic factors, including competition and specific market conditions. Intangible assets that are deemed to have definite lives are amortized over their useful lives as follows: dealer network and customer relationships: 8-19 years; trade names: 15 years; other: 5-19 years.

Goodwill is not amortized. The Company tests goodwill for impairment annually or more frequently if events or circumstances indicate that goodwill might be impaired. The Company uses qualitative factors to determine whether it is more likely than not (a likelihood of more than 50 percent) that the fair value of a reporting unit is less than its carrying value, including goodwill. The Company estimates the fair values of each of its reporting units using the income approach.

The income approach uses a reporting unit's projection of estimated future operating results and cash flows which are then discounted using a weighted average cost of capital determined based on current market conditions for the individual reporting unit. The projection uses management's best estimates of cash flows over the projection period based on estimates of annual and terminal growth rates in sales and costs, and changes in operating margins, selling, general and administrative expenses, working capital requirements and capital expenditures. Other factors used in evaluating the fair value of a reporting unit could include deterioration in the general economy, fluctuations in foreign exchange, deterioration in the industry or markets in which the reporting unit operates, an increased competitive market, regulatory or political developments in the market, increases in raw materials, labor costs or other factors that have a negative effect on earnings and cash flows, a decline in actual or budgeted earnings or cash flows, and entity specific changes in management, key personnel, strategy or customer base. If the fair value of a reporting unit is found to be less than its book value, the company will record an impairment loss equal to the excess, if any, of the book value over the fair value of its goodwill.

The fair value of reporting units that do not have goodwill are estimated using either the income or market approaches, depending on which approach is the most appropriate for each reporting unit. The fair value of the reporting units that serve operating units in supporting roles, such as the captive insurance company and the corporate reporting unit are estimated using the cost approach. The sum of the fair values of all reporting units is compared to the fair value of the consolidated Company, calculated using the market approach, which is inferred from the market capitalization of the Company at the date of the valuation, to confirm that the Company's estimation of the fair value of its reporting units is reasonable.

Determining the fair values of the Company's reporting units involves the use of significant estimates and assumptions. Due to the inherent uncertainty involved in making these estimates and assumptions, actual results could differ materially from those estimates.

Impairment of Long-lived Assets - In the event that facts and circumstances indicate the carrying amounts of long-lived assets may be impaired, an evaluation of recoverability is performed. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset are compared to the carrying amount for each asset (or group of assets) to determine if a write-down is required. If this review indicates that the assets will not be recoverable, the carrying values of the impaired assets are reduced to their estimated fair value. Fair value is estimated using discounted cash flows, prices for similar assets or other valuation techniques.

Self-Insurance Reserves - The Company retains the risk for a portion of its workers' compensation claims and general liability claims by way of a captive insurance company, Astec Insurance Company ("Astec Insurance" or the "captive"). Astec Insurance was originally incorporated under the laws of the state of Vermont but was redomiciled to the state of Tennessee in late 2017. The objectives of Astec Insurance are to improve control over and reduce the cost of claims; to improve focus on risk reduction with the development of a program structure which rewards proactive loss control; and to ensure management participation in the defense and settlement process for claims.

For general liability claims, the captive is liable for the first $1,000 per occurrence and $3,000 per year in the aggregate. The Company carries general liability, excess liability and umbrella policies for claims in excess of amounts covered by the captive.

For workers' compensation claims, the captive is liable for the first $350 per occurrence and $3,250 per year in the aggregate. The Company utilizes a large national insurance company as third-party administrator for workers' compensation claims and carries insurance coverage for claims liabilities in excess of amounts covered by the captive.

The financial statements of the captive are consolidated into the consolidated financial statements of the Company. The short-term and long-term reserves for claims and potential claims related to general liability and workers' compensation under the captive are included in accrued loss reserves or other long-term liabilities, respectively, in the consolidated balance sheets depending on the expected timing of future payments. The undiscounted reserves are actuarially determined to cover the ultimate cost of each claim based on the Company's evaluation of the type and severity of individual claims and historical information, primarily its own claims experience, along with assumptions about future events. Changes in assumptions, as well as changes in actual experience, could cause these estimates to change in the future. However, the Company does not believe it is reasonably likely that the reserve level will materially change in the foreseeable future.

The Company is self-insured for health and prescription claims under its Group Health Insurance Plan at all but one of the Company's domestic manufacturing subsidiaries. The Company carries reinsurance coverage to limit its exposure for individual health claims above certain limits. Third parties administer health claims and prescription medication claims. The Company maintains a reserve for the self-insured health plan which is included in accrued loss reserves on the Company's consolidated balance sheets. This reserve includes both unpaid claims and an estimate of claims incurred but not reported, based on historical claims and payment experience. Historically, the reserves have been sufficient to provide for claims payments. Changes in actual claims experience or payment patterns could cause the reserve to change, but the Company does not believe it is reasonably likely that the reserve level will materially change in the near future.

The remaining U.S. subsidiary is covered under a fully insured group health plan. Employees of the Company's foreign subsidiaries are insured under separate health plans. No reserves are necessary for these fully-insured health plans.

Revenue Recognition - Revenue is generally recognized on sales at the point in time when persuasive evidence of an arrangement exists, the price is fixed or determinable, the product has been delivered or services have been rendered and there is a reasonable assurance of collection of the sales proceeds. The Company generally obtains purchase authorizations from its customers for a specified amount of products at a specified price with specified delivery terms. A significant portion of the Company's equipment sales represents equipment produced in the Company's plants under short-term contracts for a specific customer project or equipment designed to meet a customer's specific requirements. Most of the equipment sold by the Company is based on standard configurations, some of which are modified to meet customer needs or specifications. The Company provides customers with technical design and performance specifications and performs pre-shipment testing to ensure the equipment performs according to design specifications, regardless of whether the Company provides installation services in addition to selling the equipment.

Certain contracts include terms and conditions pursuant to which the Company recognizes revenues upon completion of equipment production, which is subsequently stored at the Company's plant at the customer's request. Revenue is recorded on such contracts upon the customer's assumption of title and risk of ownership and when collectability is reasonably assured. In addition, there must be a fixed schedule of delivery of the goods consistent with the customer's business practices, the Company must not have retained any specific performance obligations such that the earnings process is not complete and the goods must have been segregated from the Company's inventory prior to revenue recognition.

The Company has certain sales accounted for as multiple-element arrangements, whereby revenue attributable to the sale of a product is recognized when the product is shipped, and the revenue attributable to services provided with respect to the product (such as installation services) is recognized when the service is performed. Consideration is allocated to deliverables using the relative selling price method using vendor specific objective evidence, if it exists. Otherwise, the Company uses third-party evidence of selling price or the Company's best estimate of the selling price for the deliverables. The Company evaluates sales with multiple deliverable elements (such as an agreement to deliver equipment and related installation services) to determine whether revenue related to individual elements should be recognized separately, or as a combined unit. In addition to the previously mentioned general revenue recognition criteria, the Company only recognizes revenue on individual delivered elements when there is objective and reliable evidence that the delivered element has a determinable value to the customer on a standalone basis and there is no right of return.

The Company has certain sales accounted for under the percentage of completion method using the ratio of costs incurred to estimated total costs. Revenue, in an amount equal to cost incurred, is recognized until there is sufficient information to determine the estimated profit on the project with a reasonable level of certainty. The factors considered in this evaluation include the stage of design completion, the stage of equipment manufacturing completion, the state of construction completion, the status of outstanding subcontracts, certainty of quantities of labor and materials, certainty of schedule and the relationship with the customer.

The Company presents in the consolidated statements of income any taxes assessed by a governmental authority that are directly imposed on revenue-producing transactions between the Company and its customers, such as sales, use, value-added and some excise taxes, on a net (excluded from revenue) basis.

Advertising Expense - The cost of advertising is expensed as incurred. The Company incurred $3,793, $4,045, and $4,231 in advertising costs during 2017, 2016 and 2015, respectively, which is included in selling, general and administrative expenses.

Income Taxes - Income taxes are based on pre-tax financial accounting income. Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax bases of assets and liabilities and their reported amounts. The Company periodically assesses the need to establish valuation allowances against its deferred tax assets to the extent the Company no longer believes it is more likely than not that the tax assets will be fully utilized.

The Company evaluates a tax position to determine whether it is more likely than not that the tax position will be sustained upon examination, based upon the technical merits of the position. A tax position that meets the more-likely-than-not recognition threshold is subject to a measurement assessment to determine the amount of benefit to recognize and the appropriate reserve to establish, if any. If a tax position does not meet the more-likely-than-not recognition threshold, no benefit is recognized. The Company is periodically audited by U.S. federal and state as well as foreign tax authorities. While it is often difficult to predict final outcome or timing of resolution of any particular tax matter, the Company believes its reserve for uncertain tax positions is adequate to reduce the uncertain positions to the greatest amount of benefit that is more likely than not realizable.

Product Warranty Reserve - The Company accrues for the estimated cost of product warranties at the time revenue is recognized. Warranty obligations by product line or model are evaluated based on historical warranty claims experience. For equipment, the Company's standard product warranty terms generally include post-sales support and repairs of products at no additional charge for periods ranging from three months to two years or up to a specified number of hours of operation. For parts from component suppliers, the Company relies on the original manufacturer's warranty that accompanies those parts. Generally, Company fabricated parts are not covered by specific warranty terms. Although failure of fabricated parts due to material or workmanship is rare, if it occurs, the Company's policy is to replace fabricated parts at no additional charge.

The Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of our component suppliers. Estimated warranty obligations are based upon warranty terms, product failure rates, repair costs and current period machine shipments. If actual product failure rates, repair costs, service delivery costs or post-sales support costs differ from our estimates, revisions to the estimated warranty liability may be required.

Pension and Retirement Plans - The determination of obligations and expenses under the Company's pension plan is dependent on the Company's selection of certain assumptions used by independent actuaries in calculating such amounts. Those assumptions are described in Note 12, Pension and Retirement Plans and include among others, the discount rate, expected return on plan assets and the expected mortality rates. In accordance with U.S. generally accepted accounting principles, actual results that differ from assumptions are accumulated and amortized over future periods and, therefore, generally affect the recognized expense in such periods. Significant differences in actual experience or significant changes in the assumptions used may materially affect the pension obligations and future expenses.

The Company recognizes the overfunded or underfunded status of its pension plan as an asset or liability. Actuarial gains and losses, amortization of prior service cost (credit) and amortization of transition obligations are recognized through other comprehensive income (loss) in the year in which the changes occur. The Company measures the funded status of its pension plan as of the date of the Company's fiscal year-end.

Stock-based Compensation -The Company recognizes the cost of employee services received in exchange for equity awards in the consolidated financial statements based on the grant date calculated fair value of the awards. The Company recognizes stock-based compensation expense over the period during which an employee is required to provide service in exchange for the award (the vesting period). The Company's equity awards are further described in Note 16, Shareholders' Equity.

Earnings Per Share -Basic earnings per share is based on the weighted average number of common shares outstanding and diluted earnings per share includes potential dilutive effects of restricted stock units and shares held in the Company's supplemental executive retirement plan.

The following table sets forth a reconciliation of the number of shares used in the computation of basic and diluted earnings per share:

	Year Ended December 31
	2017		2016		2015
Denominator:
Denominator for basic earnings per share		23,025		22,992		22,934
Effect of dilutive securities:
Restricted stock units		96		85		123
Supplemental executive retirement plan		63		65		63
Denominator for diluted earnings per share		23,184		23,142		23,120

Derivatives and Hedging Activities - The Company recognizes all derivatives in the consolidated balance sheets at their fair value. Derivatives that are not hedges are adjusted to fair value through income. If the derivative is a hedge, depending on the nature of the hedge, changes in the fair value of derivatives are either offset against the change in fair value of assets, liabilities, or firm commitments through income or recognized in other comprehensive income until the hedged item is recognized in income. The ineffective portion of a derivative's change in fair value is immediately recognized in income. From time to time, the Company's foreign subsidiaries enter into foreign currency exchange contracts to mitigate exposure to fluctuation in currency exchange rates. See Note 13, Derivative Financial Instruments, regarding foreign exchange contracts outstanding at December 31, 2017 and 2016.

Shipping and Handling Fees and Cost - The Company records revenues earned for shipping and handling as revenue, while the cost of shipping and handling is classified as cost of sales.

Business Combinations - The Company accounts for business combinations using the acquisition method. Accordingly, intangible assets are recorded apart from goodwill if they arise from contractual or legal rights or if they are separable from goodwill. Related third-party acquisition costs are expensed as incurred and contingent consideration is booked at its fair value as part of the purchase price. See Note 20, Business Combinations, regarding acquisitions completed by the Company in the years ended December 31, 2017 and 2016.

Subsequent Events Review - Management has evaluated events occurring between December 31, 2017 and the date these consolidated financial statements were filed with the Securities and Exchange Commission for proper recording or disclosure therein.

Recent Accounting Pronouncements -In May 2014, the Financial Accounting Standards Board ('FASB") issued Accounting Standards Update ("ASU") No. 2014-09, "Revenue from Contracts with Customers", which supersedes existing revenue guidance under U.S. GAAP. The standard's core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The implementation of this new standard will require companies to use more judgment and to make more estimates than under current guidance and to expand their disclosures to include information regarding contract assets and liabilities as well as a more disaggregated view of revenue. The standard, as amended, is effective for public companies for annual periods beginning after December 15, 2017. The Company adopted the new standard effective January 1, 2018 using the modified retrospective transition method and will expand its disclosures in the first quarter 2018 consolidated financial statements to comply with the disclosure provisions of the new rule. The Company does not expect the adoption of the standard to have a material impact on its financial position, results of operations or cash flows.

In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments - Overall (Subtopic 825-10)", which requires, among other things, equity investments with readily determinable fair values, except those accounted for under the equity method of accounting or those that result in consolidation of the investee, to be measured at fair value with changes in fair value recognized in net income. The standard is effective for public companies in fiscal years beginning after December 15, 2017, and the Company adopted the standard effective January 1, 2018. The Company does not expect the adoption of this standard to have a material impact on the Company's financial position, cash flows or results of operations.

In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)", which significantly changes the accounting for operating leases by lessees. The accounting applied by lessors is largely unchanged from that applied under previous guidance. The new guidance requires lessees to recognize lease assets and lease liabilities in the balance sheet, initially measured at the present value of the lease payments, for leases which were classified as operating leases under previous guidance. Lease cost included in the statement of income will be calculated so that the cost of the lease is allocated over the lease term, generally on a straight-line basis. Lessees may make an accounting policy election to exclude leases with a term of 12 months or less from the requirement to record related assets and liabilities. The new standard is effective for public companies for fiscal years beginning after December 15, 2018. The Company plans to adopt the new standard effective January 1, 2019. The Company does not expect the adoption of this standard to have a material impact on its results of operations or cash flows; however, the Company has not determined the impact the adoption of this new standard will have on its financial position.

In March 2016, the FASB issued ASU No. 2016-08, "Revenue from Contracts with Customers (Topic 606)", which does not change the core principles of ASU No. 2014-09 discussed above, but rather clarifies the implementation guidance in order to eliminate the potential for diversity in practice arising from inconsistent application of the principal versus agent guidance. Under the new guidance, when an entity determines it is a principal in a transaction, the entity recognizes revenue in the gross amount of consideration; however, in transactions where an entity determines it is an agent, the entity recognizes revenue in the amount of any fee or commission to which it expects to be entitled. The standard is effective for public companies for annual periods beginning after December 15, 2017. The Company adopted the new standard effective January 1, 2018. The Company does not expect the adoption of this new standard to have a material impact on the Company's financial position, results of operations or cash flows.

In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments". The standard changes how credit losses are measured for most financial assets and certain other instruments that currently are not measured through net income. The standard will require an expected loss model for instruments measured at amortized cost as opposed to the current incurred loss approach. In valuing available for sale debt securities, allowances will be required to be recorded, rather than the current approach of reducing the carrying amount, for other than temporary impairments. A cumulative adjustment to retained earnings is to be recorded as of the beginning of the period of adoption to reflect the impact of applying the provisions of the standard. The standard is effective for public companies for periods beginning after December 15, 2019 and the Company expects to adopt the new standard as of January 1, 2020. The Company has not yet determined what impact, if any, the adoption of this new standard will have on the Company's financial position results of operations or cash flows.

In August 2016, the FASB issued ASU No. 2016-15, "Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force)" which clarifies how certain cash receipts and cash payments should be presented on the statement of cash flows. The statement also addresses how the predominance principle should be applied when cash payments have aspects of more than one class of cash flows. The standard is effective for public companies in fiscal years beginning after December 15, 2017, and the Company adopted the standard effective January 1, 2018. The Company does not expect the adoption of this new standard to have a material impact on the Company's consolidated statements of cash flows.

In October 2016, the FASB issued ASU No. 2016-16, "Income Taxes (Topic 740), Intra-Entity Transfers of Assets Other Than Inventory" which requires companies to account for the income tax effects of intercompany sales and transfers of assets other than inventory, such as intangible assets, when the transfer occurs. This is a change from current guidance, which requires companies to defer the income tax effects of intercompany transfers of assets until the asset has been sold to an outside party or otherwise recognized by being depreciated, amortized, or impaired. The new guidance will require companies to defer the income tax effects of only intercompany transfers of inventory. The standard is effective for public companies in fiscal years beginning after December 15, 2017. The Company adopted the new standard effective January 1, 2018. The Company does not expect the application of this standard to have a material impact on the Company's financial position, results of operations or cash flows.

In January 2017, the FASB issued ASU No. 2017-01, "Business Combinations (Topic 805), Clarifying the Definition of a Business," which provides additional guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The standard is effective for public companies for annual or interim periods beginning after December 15, 2017. The Company adopted the new standard effective January 1, 2018. The Company does not expect the application of this standard to have a material impact on its financial position, results of operations or cash flows.

In January 2017, the FASB issued ASU No. 2017-04, "Intangibles-Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment," which eliminates Step 2 from the goodwill impairment test for public companies.  Previously, Step 2 measured a goodwill impairment loss by comparing the implied fair value of a reporting unit's goodwill with the carrying amount of that goodwill. The new guidance stipulates that an entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge would be recognized for the amount by which the carrying amount exceeds the reporting unit's fair value, up to the amount of goodwill allocated to the reporting unit. The standard is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019 with early adoption permitted. The Company elected to adopt this standard as of December 31, 2017. The application of this standard did not have a material impact on the Company's financial position, results of operations or cash flows.

In August 2017, the FASB issued ASU No. 2017-12, "Derivatives and Hedging (Topic 815), Targeted Improvements to Hedging Activities", to improve the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements. The new guidance is effective for public companies for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years with early adoption permitted in any interim period after its issuance. The Company plans to adopt the new standard effective January 1, 2019. The Company does not expect the application of this standard to have a material impact on its financial position, results of operations or cash flows.

Fair Value Measurements

3. Fair Value Measurements

The Company has various financial instruments that must be measured at fair value on a recurring basis, including marketable debt and equity securities held by Astec Insurance, and marketable equity securities held in an unqualified Supplemental Executive Retirement Plan ("SERP"). The financial assets held in the SERP also constitute a liability of the Company for financial reporting purposes. The Company's subsidiaries also occasionally enter into foreign currency exchange contracts to mitigate exposure to fluctuations in currency exchange rates.

For cash and cash equivalents, trade receivables, other receivables, revolving debt and accounts payable, the carrying amount approximates the fair value because of the short-term nature of these instruments. Investments are carried at their fair value based on quoted market prices for identical or similar assets or, where no quoted prices exist, other observable inputs for the asset. The fair values of foreign currency exchange contracts are based on quotations from various banks for similar instruments using models with market based inputs.

As indicated in the tables below, the Company has determined that its financial assets and liabilities at December 31, 2017 and 2016 are level 1 and level 2 in the fair value hierarchy:

Additionally, a significant portion of the trading equity securities are in equity money market and mutual funds and also comprise a portion of the Company's liability under its SERP. See Note 12, Pension and Retirement Plans, for additional information on these investments and the SERP.

Trading debt securities are comprised mainly of marketable debt securities held by Astec Insurance. Astec Insurance has an investment strategy that focuses on providing regular and predictable interest income from a diversified portfolio of high-quality fixed income securities.

Net unrealized gains or losses incurred on investments still held as of the end of each reporting period amounted to losses of $319, $107 and $429 in 2017, 2016 and 2015, respectively.

Goodwill

5. Goodwill

Goodwill represents the excess of the purchase price over the fair value of identifiable net assets acquired in business combinations. Current U.S. accounting guidance provides that goodwill and indefinite-lived intangible assets be tested for impairment at least annually. The Company performs the required valuation procedures each year as of December 31 after the following year's forecasts are submitted and reviewed. The valuations performed in 2017, 2016 and 2015 indicated no impairment of goodwill.

The changes in the carrying amount of goodwill by reporting segment during the years ended December 31, 2017 and 2016 are as follows:

9. Debt

On April 12, 2017, the Company and certain of its subsidiaries entered into an amended and restated credit agreement whereby the lender extended to the Company an unsecured line of credit of up to $100,000, including a sub-limit for letters of credit of up to $30,000. There were no outstanding revolving or term loan borrowings under the credit facility at December 31, 2017 or 2016. Letters of credit totaling $9,757, including $3,200 of letters of credit issued to banks in Brazil to secure the local debt of Astec do Brasil Fabricacao de Equipamentos Ltda. ("Astec Brazil"), were outstanding under the credit facility as of December 31, 2017, resulting in additional borrowing ability of $90,243 under the credit facility. The credit agreement has a five-year term expiring in April 2022. Borrowings under the agreement are subject to an interest rate equal to the daily one-month LIBOR rate plus a 0.75% margin, resulting in a rate of 2.32% as of December 31, 2017. The unused facility fee is 0.125%. Interest only payments are due monthly. The amended and restated credit agreement contains certain financial covenants, including provisions concerning required levels of annual net income and minimum tangible net worth.

The Company's South African subsidiary, Osborn Engineered Products SA (Pty) Ltd ("Osborn"), has a credit facility of $7,672 with a South African bank to finance short-term working capital needs, as well as to cover performance letters of credit, advance payment and retention guarantees. As of December 31, 2017, Osborn had no outstanding borrowings but had $813 in performance, advance payment and retention guarantees outstanding under the facility. The facility has been guaranteed by Astec Industries, Inc., but is otherwise unsecured. A 0.75% unused facility fee is charged if less than 50% of the facility is utilized. As of December 31, 2017, Osborn had available credit under the facility of $6,859. The interest rate is 0.25% less than the South Africa prime rate, resulting in a rate of 10.0% as of December 31, 2017.

The Company's Brazilian subsidiary has outstanding working capital loans totaling $3,402 from Brazilian banks with interest rates ranging from 10.4% to 11.0%. The loans' maturity dates ranging from November 2018 to April 2024 and are secured by Astec Brazil's manufacturing facility and also by letters of credit totaling $3,200 issued by Astec Industries, Inc. Additionally, Astec Brazil has various five-year equipment financing loans outstanding with Brazilian banks in the aggregate of $642 as of December 31, 2017 that have interest rates ranging from 3.5% to 16.3%. These equipment loans have maturity dates ranging from September 2018 to April 2020. Astec Brazil's loans are included in the accompanying consolidated balance sheets as current maturities of long-term debt of $2,469 and long-term debt of $1,575 as of December 31, 2017.

10. Product Warranty Reserves

The Company warrants its products against manufacturing defects and performance to specified standards. The warranty period and performance standards vary by product, but generally range from three months to two years or up to a specified number of hours of operation. The Company estimates the costs that may be incurred under its warranties and records a liability at the time product sales are recorded. The warranty liability is primarily based on historical claim rates, nature of claims and the associated costs.

Changes in the Company's product warranty liability during 2017, 2016 and 2015 are as follows:

	2017			2016			2015
Reserve balance, beginning of year	$	13,156		$	9,100		$	10,032

Accrued Loss Reserves

11. Accrued Loss Reserves

The Company accrues reserves for losses related to known workers' compensation and general liability claims that have been incurred but not yet paid or are estimated to have been incurred but not yet reported to the Company. The undiscounted reserves are actuarially determined based on the Company's evaluation of the type and severity of individual claims and historical information, primarily its own claim experience, along with assumptions about future events. Changes in assumptions, as well as changes in actual experience, could cause these estimates to change in the future. Total accrued loss reserves at December 31, 2017 were $8,119 and $7,892 at December 31, 2016, of which $5,615 and $5,040 were included in other long-term liabilities at December 31, 2017 and 2016, respectively.

Pension and Retirement Plans

12. Pension and Retirement Plans

Prior to December 31, 2003, all employees of the Company's Kolberg-Pioneer, Inc. subsidiary were covered by a defined benefit pension plan. After December 31, 2003, all benefit accruals under the plan ceased and no new employees could become participants in the plan. Benefits paid under this plan are based on years of service multiplied by a monthly amount. The Company's funding policy for the plan is to make at least the minimum annual contributions required by applicable regulations.

The Company's investment strategy for the plan is to earn a rate of return sufficient to match or exceed the long-term growth of pension liabilities. The investment policy states that the Plan Committee in its sole discretion shall determine the allocation of plan assets among the following four asset classes: cash equivalents, fixed-income securities, domestic equities and international equities. The Plan Committee attempts to ensure adequate diversification of the invested assets through investment in an exchange traded mutual fund that invests in a diversified portfolio of stocks, bonds and money market securities.

The following provides information regarding benefit obligations, plan assets and the funded status of the plan:

	Pension Benefits
	2017			2016

Discount rate	3.50	%	4.00	%
Expected return on plan assets	6.25	%	6.25	%
Rate of compensation increase	N/A		N/A

The measurement date used for the plan was December 31. In determining the expected return on plan assets, the historical experience of the plan assets, the current and expected allocation of the plan assets and the expected long-term rates of return were considered.

All assets in the plan are invested in an exchange traded mutual fund (level 1 in the fair value hierarchy). The allocation of assets within the mutual fund as of December 31 and the target asset allocation ranges by asset category are as follows:

Asset Category	Actual Allocation 2017			Actual Allocation 2016			2017 & 2016 Target Allocation Ranges
Equity securities		49.4	%		63.6	%		40 - 65	%
Debt securities		43.2	%		33.5	%		30 - 50	%
Cash and Equivalents		7.4	%		2.9	%		0 - 15	%
Total		100.0	%		100.0	%

Net periodic benefit cost for 2017, 2016 and 2015 included the following components:

	Pension Benefits
	2017			2016			2015
Components of net periodic benefit cost
Interest cost	$	630		$	650		$	596
Expected return on plan assets		(720	)		(782	)		(840	)

Discount rate		4.00	%		4.28	%		3.81	%
Expected return on plan assets		6.25	%		7.00	%		7.00	%

No contributions are expected to be funded by the Company during 2018.

Amounts in accumulated other comprehensive loss expected to be recognized in net periodic benefit cost in 2018 for the amortization of a net loss is $466.

The following estimated future benefit payments are expected in the years indicated:

	Pension Benefits
2018	$	800
2019		830
2020		860
2021		890
2022		9,100
2023 - 2027		4,810

The Company sponsors a 401(k) defined contribution plan to provide eligible employees with additional income upon retirement. The Company's contributions to the plan are based on employee contributions. The Company's contributions totaled $7,182, $5,943 and $5,292 in 2017, 2016 and 2015, respectively.

The Company maintains a SERP for certain of its executive officers. The plan is a non-qualified deferred compensation plan administered by the Board of Directors of the Company, pursuant to which the Company makes quarterly cash contributions of a certain percentage of executive officers' compensation. Investments are self-directed by participants and can include Company stock. Upon retirement, participants receive their apportioned share of the plan assets in the form of cash.

Assets of the SERP consist of the following:

	December 31, 2017						December 31, 2016
	Cost			Market			Cost			Market
Company stock		$	1,960		$	3,589		$	1,958		$	4,455
Equity securities			4,589			4,963			3,474			3,427
Total		$	6,549		$	8,552		$	5,432		$	7,882

The Company periodically adjusts the deferred compensation liability such that the balance of the liability equals the total fair market value of all assets held by the trust established under the SERP. Such liabilities are included in other long-term liabilities on the consolidated balance sheets. The equity securities are included in investments in the consolidated balance sheets and classified as trading equity securities. See Note 4, Investments, for additional information. The cost of the Company stock held by the plan is included as a reduction in shareholders' equity in the consolidated balance sheets.

The change in the fair market value of Company stock held in the SERP results in a charge or credit to selling, general and administrative expenses in the consolidated statements of income because the acquisition cost of the Company stock in the SERP is recorded as a reduction of shareholders' equity and is not adjusted to fair market value; however, the related liability is adjusted to the fair market value of the stock as of each period end. The Company recognized income of $575 in 2017 and expense of $1,742 and $241 in 2016 and 2015, respectively, related to the change in the fair value of the Company stock held in the SERP.

Derivative Financial Instruments

13. Derivative Financial Instruments

The Company is exposed to certain risks relating to its ongoing business operations. The primary risk managed by using derivative instruments is foreign currency risk. From time to time, the Company's foreign subsidiaries enter into foreign currency exchange contracts to mitigate exposure to fluctuations in currency exchange rates. The fair value of the derivative financial instrument is recorded on the Company's consolidated balance sheets and is adjusted to fair value at each measurement date. The changes in fair value are recognized in the consolidated statements of income in the current period. The Company does not engage in speculative transactions nor does it hold or issue derivative financial instruments for trading purposes. The average U.S. dollar equivalent notional amount of outstanding foreign currency exchange contracts was $11,099 during 2017. At December 31, 2017, the Company reported $112 of derivative liabilities in other current liabilities. The Company reported $144 of derivative assets in other current assets and $89 of derivative liabilities in other current liabilities at December 31, 2016. The Company recognized, as a component of cost of sales, a net loss on the change in fair value of derivative instruments of $663 and $336 for the years ended December 31, 2017 and 2016, respectively. The Company recognized a net gain on the change in fair value of derivative instruments of $606 for the year ended December 31, 2015. There were no derivatives that were designated as hedges at December 31, 2017 or 2016.

Total income tax provision	$	19,627		$	32,107		$	20,007

The Company's income tax provision is computed based on the domestic and foreign federal statutory rates and the average state statutory rates, net of related federal benefit.

The provision for income taxes differs from the amount computed by applying the statutory federal income tax rate to income before income taxes. A reconciliation of the provision for income taxes at the statutory federal income tax rate to the amount provided is as follows:

	Year Ended December 31

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

Significant components of the Company's deferred tax assets and liabilities are as follows:

	December 31
	2017			2016
Deferred tax assets:
Inventory reserves	$	4,287		$	8,507
Warranty reserves		3,560			4,527

Outside basis differences		--			511
Total deferred tax liabilities		16,743			24,732
Total net deferred assets	$	1,067		$	1,007

As of December 31, 2017, the Company has state net operating loss carryforwards of $17,579 and foreign net operating loss carryforwards of approximately $19,876, which will be available to offset future taxable income. If not used, these carryforwards will expire between 2018 and 2030. A significant portion of the valuation allowance for deferred tax assets relates to the future utilization of state and foreign net operating loss and state tax credit carryforwards. Future utilization of these net operating loss and state tax credit carryforwards is evaluated by the Company on a periodic basis and the valuation allowance is adjusted accordingly. In 2017, the valuation allowance on these carryforwards was increased by $7 due to the uncertainty about whether certain entities will realize their state and foreign net operating loss carryforwards. The Company has also determined that the recovery of certain other deferred tax assets is uncertain. The valuation allowance for these deferred tax assets was increased by $31 during 2017.

The following table represents a roll forward of the deferred tax asset valuation allowance for the years ended December 31, 2017, 2016 and 2015:

	Year Ended December 31
	2017			2016			2015
Allowance balance, beginning of year	$	8,280		$	8,065		$	6,029
Provision		1,585			1,639			2,036

Undistributed earnings of the Company's Canadian subsidiary, Breaker Technology Ltd. ("BTL") and South African subsidiary, Osborn Engineered Products SA, (PTY), Ltd. ("Osborn") are considered to be indefinitely reinvested; accordingly, no provision for U.S. federal and state income taxes has been provided thereon. As of December 31, 2017, the cumulative amounts of undistributed GAAP earnings for BTL and Osborn are $4,026 and $28,249, respectively. A portion of these amounts may be subject to taxation under the one-time transition tax included in the Tax Cuts and Jobs Act of 2017. Based upon the provisions in the Tax Cuts and Jobs Act of 2017, any future qualified dividends out of these amounts will not be subject to U.S. income taxes. However, upon any future inclusion as Subpart F income or capital gains, the Company would be subject to additional U.S. income taxes (subject to an adjustment for foreign tax credits). Upon any repatriation, withholding taxes due to the foreign jurisdictions may have to be paid. At this time, it is not practicable to determine the amount of the unrecognized deferred tax liability for temporary differences related to investments in foreign subsidiaries.

The Company files income tax returns in the U.S. federal jurisdiction, and in various state and foreign jurisdictions. The Company is no longer subject to U.S. federal income tax examinations by authorities for years prior to 2014. With few exceptions, the Company is no longer subject to state and local or non-U.S. income tax examinations by authorities for years prior to 2012.

The Company has a liability for unrecognized tax benefits of $365 and $238 (excluding accrued interest and penalties) as of December 31, 2017 and 2016, respectively. The Company recognizes interest and penalties accrued related to unrecognized tax benefits in tax expense. The Company recognized tax benefits of $22 and $16 in 2017 and 2016, respectively, for penalties and interest related to amounts that were settled for less than previously accrued. The net total amount of unrecognized tax benefits that, if recognized, would affect the Company's effective tax rate is $370 and $238 at December 31, 2017 and 2016, respectively. The Company does not expect a significant increase or decrease to the total amount of unrecognized tax benefits within the next twelve months.

A reconciliation of the beginning and ending unrecognized tax benefits excluding interest and penalties is as follows:

	Year Ended December 31
	2017		2016			2015
Balance, beginning of year	$	238	$	603		$	2,585
Additions for tax positions related to the current year		127		73			206
Additions for tax positions related to prior years		--		162			549
Reductions due to lapse of statutes of limitations		--		(16	)		(162	)
Decreases related to settlements with tax authorities		--		(584	)		(2,575	)
Balance, end of year	$	365	$	238		$	603

The December 31, 2017 balance of unrecognized tax benefits includes no tax positions for which the ultimate deductibility is highly certain but the timing of such deductibility is uncertain. Accordingly, there is no impact to the deferred tax accounting for certain tax benefits.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the "Tax Act") was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a federal corporate tax rate decrease from 35% to 21% for tax years beginning after December 31, 2017, the transition of U.S international taxation from a worldwide tax system to a territorial system and a one-time transition tax on the mandatory deemed repatriation of foreign earnings. The Company's fourth quarter 2017 provision for income taxes was reduced by $1,056, (comprised of a $1,548 reduction in income tax expense recorded in connection with the remeasurement of deferred tax assets and liabilities and $492 of additional income tax expense recorded in connection with the transition tax on the mandatory deemed repatriation of foreign earnings) due to applying the provisions of the Tax Act.

On December 22, 2017, Staff Accounting Bulletin No. 118 ("SAB 118") was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Act. In accordance with SAB 118, the Company determined that the $492 additional 2017 income tax expense is a provisional amount and constitutes a reasonable estimate at December 31, 2017, based upon the best information currently available. The ultimate impact may differ from the provisional amount, possibly materially, due to, among other things, additional analysis, changes in interpretations and assumptions the Company has made, additional regulatory guidance that may be issued and actions the Company may take as a result of the Tax Act. Any subsequent adjustment to the amount will be recorded to current income tax expense when the analysis is complete, which is expected in 2018 shortly after the filing of the Company's 2017 U.S. income tax return.

While the Tax 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 the Company to include, in its U.S. income tax return, foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary's tangible assets. The Company has elected to account for GILTI tax in the period in which it is incurred, and therefore, has not provided any deferred tax impacts of GILTI in its consolidated financial statements for the year ended December 31, 2017.

The BEAT provisions in the Tax Act eliminates the deduction of certain base-erosion payments made to related foreign corporations, and impose a minimum tax, if greater than regular tax. The Company does not expect it will be subject to this tax, and therefore, has not included any tax impacts of BEAT in its consolidated financial statements for the year ended December 31, 2017.

The changes to existing U.S. tax laws as a result of the Tax Act, which we believe have the most significant impact on the Company's federal income taxes are as follows:

Reduction of the U.S. Corporate Income Tax Rate: The Company measures deferred tax assets and liabilities using enacted tax rates that will apply in the years in which the temporary differences are expected to be recovered or paid. Accordingly, the Company recognized a deferred tax benefit and related increase in deferred tax assets of $1,548 in its 2017 consolidated financial statements due to the remeasurement necessitated by the Tax Act's provision reducing the reduction in the U.S. corporate income tax rate from 35% to 21%. This benefit is attributable to the Company being in a net deferred tax liability position when considering only U.S. federal deferred items. The Company has significant deferred tax assets related to foreign jurisdictions and U.S. state income taxes.

Transition Tax on Foreign Earnings: The Company recognized a provisional income tax expense of $492 for the year ended December 31, 2017 related to the one-time transition tax on certain foreign earnings. The determination of the transition tax requires further analysis regarding the amount and composition of the Company's historical foreign earnings and foreign taxes, which is expected to be completed in 2018.

Repeal of Domestic Production Activities Deduction: While not effective until 2018, the Tax Act repeals the Domestic Production Activities Deduction ("DPAD") previously provided under IRC §199. The DPAD benefit has historically been very material to the Company's federal income taxes. The DPAD benefits included in the effective tax rate reconciliations for 2017, 2016 and 2015 were $1,661, $1,641 and $1,174, respectively.

Contingent Matters [Abstract]

Contingent Matters

15. Contingent Matters

Certain customers have financed purchases of Company products through arrangements in which the Company is contingently liable for customer debt of $3,805 at December 31, 2017. These arrangements expire at various dates through December 2020 and provide that the Company will receive the lender's full security interest in the equipment financed if the Company is required to fulfill its contingent liability under these arrangements. The Company has recorded a liability of $836 related to these guarantees as of December 31, 2017.

In addition, the Company is contingently liable under letters of credit issued by a lender totaling $9,757 as of December 31, 2017, including $3,200 of letters of credit guaranteeing certain Astec Brazil bank debt. The outstanding letters of credit expire at various dates through October 2020. As of December 31, 2017, the Company's foreign subsidiaries are contingently liable for a total of $3,557 in performance letters of credit, advance payments and retention guarantees. The maximum potential amount of future payments under these letters of credit and guarantees for which the Company could be liable is $13,314 as of December 31, 2017.

The Company has a sales contract with the purchaser of a large wood pellet plant, on which revenues of $7,987 and $135,187 were recorded in 2017 and 2016, respectively. As the plant has not yet met the production output and the operational specifications set forth in the original contract, as amended through December 31, 2017, the Company entered into a contract amendment in February 2018, whereby the Company agreed to compensate the customer for production shortfalls caused by the Company and other potential costs (depending upon the market price of wood pellets), from January 1, 2018 through June 15, 2018. The Company incurred production shortfalls in January and February 2018.

The Company is currently a party to various claims and legal proceedings that have arisen in the ordinary course of business. If management believes that a loss arising from such claims and legal proceedings is probable and can reasonably be estimated, the Company records the amount of the loss (excluding estimated legal fees) or the minimum estimated liability when the loss is estimated using a range and no point within the range is more probable than another. As management becomes aware of additional information concerning such contingencies, any potential liability related to these matters is assessed and the estimates are revised, if necessary. If management believes that a loss arising from such claims and legal proceedings is either (i) probable but cannot be reasonably estimated or (ii) reasonably possible but not probable, the Company does not record the amount of the loss, but does make specific disclosure of such matter. Based upon currently available information and with the advice of counsel, management believes that the ultimate outcome of its current claims and legal proceedings, individually and in the aggregate, will not have a material adverse effect on the Company's financial position, cash flows or results of operations. However, claims and legal proceedings are subject to inherent uncertainties and rulings unfavorable to the Company could occur. If an unfavorable ruling were to occur, there exists the possibility of a material adverse effect on the Company's financial position, cash flows or results of operations.

Shareholders' Equity

16. Shareholders' Equity

The Company rewards key members of management with restricted stock units ("RSUs") each year based upon the financial performance of the Company and its subsidiaries. Under the terms of the Company's shareholder-approved 2011 Incentive Plan, up to 700 shares of newly-issued Company stock is available for awards. Awards granted in 2016 and prior vest at the end of five years from the date of grant, or at the time a recipient retires after reaching age 65, if earlier, while awards granted after 2016 are scheduled to have a three-year vesting period. Additional RSUs are granted to the Company's outside directors under the Company's Non-Employee Directors Compensation Plan with a one-year vesting period. The fair value of the RSUs vested during 2017, 2016 and 2015 was $1,991, $3,289 and $2,785, respectively. The grant date tax benefit was increased by $290, $220 and $336, respectively, upon the vesting of RSUs in 2017, 2016 and 2015.

Compensation expense of $2,978, $2,426 and $1,019 was recorded in the years ended December 31, 2017, 2016 and 2015, respectively, to reflect the fair value of RSUs granted (or anticipated to be granted for 2017 performance) amortized over the portion of the vesting period occurring during the period. Related income tax benefits of $1,132, $934 and $362 were recorded in 2017, 2016 and 2015, respectively. Based upon the grant date fair value of RSUs, it is anticipated that $5,210 of additional compensation costs will be recognized in future periods through 2021 for RSUs earned through December 31, 2017. The weighted average period over which this additional compensation cost will be expensed is 2.6 years. RSUs do not participate in Company-paid dividends.

Changes in restricted stock units during the year ended December 31, 2017 are as follows:

	2017			Weighted AverageGrant Date Fair Value
Unvested restricted stock units, beginning of year		112		$	41.48
Units granted		83			65.20
Units forfeited		(3	)		53.11
Units vested		(31	)		43.51
Unvested restricted stock units, end of year		161			53.09

The grant date fair value of the restricted stock units granted during 2017, 2016 and 2015 was $5,399, $1,946 and $937, respectively.

Operations by Industry Segment and Geographic Area

17. Operations by Industry Segment and Geographic Area

The Company has three reportable segments, each of which is comprised of multiple business units that offer similar products and services and meet the requirements for aggregation. A brief description of each segment is as follows:

Infrastructure Group - This segment consists of five business units, three of which design, engineer, manufacture and market a complete line of portable, stationary and relocatable hot-mix asphalt plants, wood pellet plants, asphalt pavers, material transfer vehicles, soil stabilizing – reclaiming machinery, milling machines, paver screeds and related ancillary equipment. The other two business units in this segment primarily operate as Company-owned dealers in the foreign countries in which they are domiciled. These two business units sell, service and install products produced by the manufacturing subsidiaries of the Company, and a majority of their sales are to customers in the infrastructure industry. The principal purchasers of the products produced by this group are asphalt producers, highway and heavy equipment contractors, wood pellet processors and foreign and domestic governmental agencies. The Infrastructure Group had sales to one pellet plant customer totaling $7,987, or 0.7% of total Company sales in 2017 and $135,187, or 11.8% of total Company sales in 2016. Portions of the equipment sold to this customer were manufactured by each of the Company's segments.

Aggregate and Mining Group - This segment consists of eight business units that design, engineer, manufacture and market a complete line of jaw crushers, cone crushers, horizontal shaft impactors, vertical shaft impactors, material handling, roll rock crushers and stationary rockbreaker systems, vibrating feeders and high frequency vibrating screens, conveyors, inclined, vertical and horizontal screens and sand classifying and washing equipment. The principal purchasers of products produced by this group are distributors, open mine operators, quarry operators, port and inland terminal operators, highway and heavy equipment contractors and foreign and domestic governmental agencies.

Energy Group - This segment consists of six business units that design, engineer, manufacture and market a complete line of drilling rigs for the oil and gas, geothermal and water well industries, high pressure diesel pump trailers for fracking and cleaning oil and gas wells, concrete plants, commercial and industrial burners, combustion control systems, a variety of industrial heaters to fit a broad range of applications including heating equipment for refineries, roofing material plants, chemical processing, rubber plants, oil sands and energy related processing, heat transfer processing equipment, thermal fluid storage tanks, waste heat recovery equipment, whole-tree pulpwood and biomass chippers and horizontal grinders. The principal purchasers of products produced by this group are oil, gas and water well drilling industry contractors, processors of oil, gas and biomass for energy production, ready mix concrete producers and contractors in the construction and demolition recycling markets. This group includes the operations of RexCon, Inc., which was acquired in October 2017.

Corporate - This category consists of business units that do not meet the requirements for separate disclosure as an operating segment or inclusion in one of the other reporting segments and includes the Company's parent company, Astec Industries, Inc., and a captive insurance company. The Company evaluates performance and allocates resources to its operating segments based on profit or loss from operations before U.S. federal income taxes and corporate overhead and thus these costs are included in the Corporate category.

The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies. Intersegment sales and transfers are valued at prices comparable to those for unrelated parties.

20. Business Combinations

In October, 2017, the Company acquired substantially all of the assets and liabilities of RexCon, Inc. ("RexCon") for a total purchase price of $26,443. The purchase price was paid in cash with $3,000 deposited into escrow for a period of time not to exceed 18 months pending final resolution of certain post-closing adjustments and any indemnification claims. The Company's preliminary allocation of the purchase price includes the recognition of $3,488 of goodwill and $7,778 of other intangible assets consisting of non-compete agreements (5-year useful life), technology (19-year useful life), trade names (15-year useful life), and customer relationships (18-year useful life). The revenues and results of operations of RexCon were not significant in relation to the Company's consolidated financial statements for the period ended December 31, 2017 and would not have been material on a proforma basis to any earlier period. RexCon's operating results are included in the Company's Energy Group beginning in the fourth quarter of 2017.

RexCon, located in Burlington, Wisconsin was founded in 2003 through an asset acquisition with the original company founded over 100 years ago.  RexCon is a manufacturer of high-quality stationary and portable, central mix and ready mix concrete batch plants, concrete mixers and concrete paving equipment.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2017

Summary of Significant Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation - The consolidated financial statements include the accounts of Astec Industries, Inc. and its domestic and foreign subsidiaries (the "Company"). The Company's significant wholly-owned and consolidated subsidiaries at December 31, 2017 are as follows:

Astec Australia Pty Ltd	Astec do Brasil Fabricacao de Equipamentos Ltda. (92% owned)
Astec, Inc.	Astec Insurance Company
Astec Mobile Machinery GmbH	Astec Mobile Screens, Inc.
Breaker Technology, Inc.	Breaker Technology Ltd.
Carlson Paving Products, Inc.	CEI Enterprises, Inc.
GEFCO, Inc.	Heatec, Inc.
Johnson Crushers International, Inc.	Kolberg-Pioneer, Inc.
Osborn Engineered Products SA (Pty) Ltd	Peterson Pacific Corp.
(99% owned)	Power Flame Incorporated
RexCon, Inc.	Roadtec, Inc.
Telestack Limited	Telsmith, Inc.

All intercompany accounts and transactions have been eliminated in consolidation. Certain reclassifications have been made to the 2016 consolidated financial statements to conform to the 2017 presentation.

Use of Estimates

Use of Estimates - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported and disclosed in the financial statements and accompanying notes. Actual results could differ from those estimates.

Foreign Currency Translation

Foreign Currency Translation - Subsidiaries located in Australia, Brazil, Canada, Germany, Northern Ireland, and South Africa operate primarily using local functional currencies. Accordingly, assets and liabilities of these subsidiaries are translated using exchange rates in effect at the end of the period, and revenues and costs are translated using average exchange rates for the period. The resulting adjustments are presented as a separate component of accumulated other comprehensive loss. Foreign currency transaction gains and losses, net are included in cost of sales and amounted to a gain of $431 in 2017 and losses of $246 and $1,377 in 2016 and 2015, respectively.

Fair Value of Financial Instruments

Fair Value of Financial Instruments - For cash and cash equivalents, trade receivables, other receivables, revolving debt and accounts payable, the carrying amount approximates the fair value because of the short-term nature of those instruments. Trading equity investments are valued at their estimated fair value based on their quoted market prices and debt securities are valued based upon a mix of observable market prices and model driven prices derived from a matrix of observable market prices for assets with similar characteristics obtained from a nationally recognized third party pricing service.

Financial assets and liabilities are categorized as of the end of each reporting period based upon the level of judgment associated with the inputs used to measure their fair value. The inputs used to measure the fair value are identified in the following hierarchy:

Level 1 -                 Unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2 - Unadjusted quoted prices in active markets for similar assets or liabilities; or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active; or inputs other than quoted prices that are observable for the asset or liability.

Level 3 - Inputs reflect management's best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.

All financial assets and liabilities held by the Company at December 31, 2017 and 2016 are classified as Level 1 or Level 2, as summarized in Note 3, Fair Value Measurements.

Cash and Cash Equivalents

Cash and Cash Equivalents - All highly liquid investments with an original maturity of three months or less when purchased are considered to be cash and cash equivalents.

Investments

Investments - Investments consist primarily of investment-grade marketable securities. Trading securities are carried at fair value, with unrealized holding gains and losses included in net income. Realized gains and losses are accounted for on the specific identification method. Purchases and sales are recorded on a trade date basis. Management determines the appropriate classification of its investments at the time of acquisition and reevaluates such determination at each balance sheet date.

Concentration of Credit Risk

Concentration of Credit Risk - The Company sells products to a wide variety of customers. Accounts receivable are carried at their outstanding principal amounts, less an allowance for doubtful accounts. The Company extends credit to its customers based on an evaluation of the customers' financial condition generally without requiring collateral, although the Company normally requires advance payments or letters of credit on large equipment orders. Credit risk is driven by conditions within the economy and the industry and is principally dependent on each customer's financial condition. To minimize credit risk, the Company monitors credit levels and financial conditions of customers on a continuing basis. After considering historical trends for uncollectible accounts, current economic conditions and specific customer recent payment history and financial stability, the Company records an allowance for doubtful accounts at a level which management believes is sufficient to cover probable credit losses. Amounts are deemed past due when they exceed the payment terms agreed to by the customer in the sales contract. Past due amounts are charged off when reasonable collection efforts have been exhausted and the amounts are deemed uncollectible by management. As of December 31, 2017, concentrations of credit risk with respect to receivables are limited due to the wide variety of customers.

Allowance for Doubtful Accounts

Allowance for Doubtful Accounts - The following table represents a rollforward of the allowance for doubtful accounts for the years ended December 31, 2017, 2016 and 2015:

	Year Ended December 31

Other		31			(46	)		(72	)
Allowance balance, end of year	$	1,716		$	1,511		$	1,837

Inventories

Inventories - The Company's inventory is comprised of raw materials, work-in-process, finished goods and used equipment.

Raw material inventory is comprised of purchased steel and other purchased items for use in the manufacturing process or held for sale for the after-market parts business. The category also includes the manufacturing cost of completed equipment sub-assemblies produced for either integration into equipment manufactured at a later date or for sale in the Company's after-market parts business.

Work-in-process inventory consists of the value of materials, labor and overhead incurred to date in the manufacturing of incomplete equipment or incomplete equipment sub-assemblies being produced.

Finished goods inventory consists of completed equipment manufactured for sale to customers.

Used equipment inventory consists of equipment accepted in trade or purchased on the open market. The category also includes equipment rented to prospective customers on a short-term or month-to-month basis. Used equipment is valued at the lower of acquired or trade-in cost or net realizable value determined on each separate unit. Each unit of rental equipment is valued at the lower of original manufacturing, acquired or trade-in cost or net realizable value.

Inventories are valued at the lower of cost (first-in, first-out) or net realizable value, which requires the Company to make specific estimates, assumptions and judgments in determining the amount, if any, of reductions in the valuation of inventories to their net realizable values. The net realizable values of the Company's products are impacted by a number of factors, including changes in the price of steel, competitive sales pricing, quantities of inventories on hand, the age of the individual inventory items, market acceptance of the Company's products, the Company's normal gross margins, actions by our competitors, the condition of our used and rental inventory and general economic factors. Once an inventory item's value has been deemed to be less than cost, a net realizable value allowance is calculated and a new "cost basis" for that item is effectively established. This new cost is retained for that item until such time as the item is disposed of or the Company determines that an additional write-down is necessary. Additional write-downs may be required in the future based upon changes in assumptions due to general economic downturns in the markets in which the Company operates, changes in competitor pricing, new product design or other technological advances introduced by the Company or its competitors and other factors unique to individual inventory items.

The most significant component of the Company's inventory is steel. A significant decline in the market price of steel could result in a decline in the market value of the equipment or parts we sell. During periods of significant declining steel prices, the Company reviews the valuation of its inventories to determine if reductions are needed in the recorded value of inventory on hand to its net realizable value.

The Company reviews the individual items included in its finished goods, used equipment and rental equipment inventory on a model-by-model or unit-by-unit basis to determine if any item's net realizable value is below its carrying value. This analysis is expanded to include items in work-in-process and raw material inventory if factors indicate those items may also be impacted. In performing this review, judgments are made and, in addition to the factors discussed above, additional consideration is given to the age of the specific items of used or rental inventory, prior sales offers or lack thereof, the physical condition of the specific items and general market conditions for the specific items. Additionally, an analysis of raw material inventory is performed to calculate reserves needed for obsolete inventory based upon quantities of items on hand, the age of those items and their recent and expected future usage or sale.

When the Company determines that the value of inventory has become impaired through damage, deterioration, obsolescence, changes in price levels, excessive levels of inventory or other causes, the Company reduces the carrying value to the net realizable value based on estimates, assumptions and judgments made from the information available at that time. Abnormal amounts of idle facility expense, freight, handling cost and wasted materials are recognized as current period charges.

Property and Equipment

Property and Equipment - Property and equipment is stated at cost. Depreciation is calculated for financial reporting purposes using the straight-line method based on the estimated useful lives of the assets as follows: airplanes (20 years), buildings (40 years) and equipment (3 to 10 years). Both accelerated and straight-line methods are used for tax compliance purposes. Routine repair and maintenance costs and planned major maintenance are expensed when incurred.

Goodwill and Other Intangible Assets

Goodwill and Other Intangible Assets - The Company classifies intangible assets as either intangible assets with definite lives subject to amortization or goodwill.

The Company tests intangible assets with definite lives for impairment if conditions exist that indicate the carrying value may not be recoverable. Such conditions may include an economic downturn in a geographic market or a change in the assessment of future operations. An impairment charge is recorded when the carrying value of the definite lived intangible asset is not recoverable by the future undiscounted cash flows expected to be generated from the use of the asset.

The Company determines the useful lives of identifiable intangible assets after considering the specific facts and circumstances related to each intangible asset. Factors considered when determining useful lives include the contractual terms of agreements, the history of the asset, the Company's long-term strategy for the use of the asset, any laws or other local regulations which could impact the useful life of the asset, and other economic factors, including competition and specific market conditions. Intangible assets that are deemed to have definite lives are amortized over their useful lives as follows: dealer network and customer relationships: 8-19 years; trade names: 15 years; other: 5-19 years.

Goodwill is not amortized. The Company tests goodwill for impairment annually or more frequently if events or circumstances indicate that goodwill might be impaired. The Company uses qualitative factors to determine whether it is more likely than not (a likelihood of more than 50 percent) that the fair value of a reporting unit is less than its carrying value, including goodwill. The Company estimates the fair values of each of its reporting units using the income approach.

The income approach uses a reporting unit's projection of estimated future operating results and cash flows which are then discounted using a weighted average cost of capital determined based on current market conditions for the individual reporting unit. The projection uses management's best estimates of cash flows over the projection period based on estimates of annual and terminal growth rates in sales and costs, and changes in operating margins, selling, general and administrative expenses, working capital requirements and capital expenditures. Other factors used in evaluating the fair value of a reporting unit could include deterioration in the general economy, fluctuations in foreign exchange, deterioration in the industry or markets in which the reporting unit operates, an increased competitive market, regulatory or political developments in the market, increases in raw materials, labor costs or other factors that have a negative effect on earnings and cash flows, a decline in actual or budgeted earnings or cash flows, and entity specific changes in management, key personnel, strategy or customer base. If the fair value of a reporting unit is found to be less than its book value, the company will record an impairment loss equal to the excess, if any, of the book value over the fair value of its goodwill.

The fair value of reporting units that do not have goodwill are estimated using either the income or market approaches, depending on which approach is the most appropriate for each reporting unit. The fair value of the reporting units that serve operating units in supporting roles, such as the captive insurance company and the corporate reporting unit are estimated using the cost approach. The sum of the fair values of all reporting units is compared to the fair value of the consolidated Company, calculated using the market approach, which is inferred from the market capitalization of the Company at the date of the valuation, to confirm that the Company's estimation of the fair value of its reporting units is reasonable.

Determining the fair values of the Company's reporting units involves the use of significant estimates and assumptions. Due to the inherent uncertainty involved in making these estimates and assumptions, actual results could differ materially from those estimates.

Impairment of Long-lived Assets

Impairment of Long-lived Assets - In the event that facts and circumstances indicate the carrying amounts of long-lived assets may be impaired, an evaluation of recoverability is performed. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset are compared to the carrying amount for each asset (or group of assets) to determine if a write-down is required. If this review indicates that the assets will not be recoverable, the carrying values of the impaired assets are reduced to their estimated fair value. Fair value is estimated using discounted cash flows, prices for similar assets or other valuation techniques.

Self-Insurance Reserves

Self-Insurance Reserves - The Company retains the risk for a portion of its workers' compensation claims and general liability claims by way of a captive insurance company, Astec Insurance Company ("Astec Insurance" or the "captive"). Astec Insurance was originally incorporated under the laws of the state of Vermont but was redomiciled to the state of Tennessee in late 2017. The objectives of Astec Insurance are to improve control over and reduce the cost of claims; to improve focus on risk reduction with the development of a program structure which rewards proactive loss control; and to ensure management participation in the defense and settlement process for claims.

For general liability claims, the captive is liable for the first $1,000 per occurrence and $3,000 per year in the aggregate. The Company carries general liability, excess liability and umbrella policies for claims in excess of amounts covered by the captive.

For workers' compensation claims, the captive is liable for the first $350 per occurrence and $3,250 per year in the aggregate. The Company utilizes a large national insurance company as third-party administrator for workers' compensation claims and carries insurance coverage for claims liabilities in excess of amounts covered by the captive.

The financial statements of the captive are consolidated into the consolidated financial statements of the Company. The short-term and long-term reserves for claims and potential claims related to general liability and workers' compensation under the captive are included in accrued loss reserves or other long-term liabilities, respectively, in the consolidated balance sheets depending on the expected timing of future payments. The undiscounted reserves are actuarially determined to cover the ultimate cost of each claim based on the Company's evaluation of the type and severity of individual claims and historical information, primarily its own claims experience, along with assumptions about future events. Changes in assumptions, as well as changes in actual experience, could cause these estimates to change in the future. However, the Company does not believe it is reasonably likely that the reserve level will materially change in the foreseeable future.

The Company is self-insured for health and prescription claims under its Group Health Insurance Plan at all but one of the Company's domestic manufacturing subsidiaries. The Company carries reinsurance coverage to limit its exposure for individual health claims above certain limits. Third parties administer health claims and prescription medication claims. The Company maintains a reserve for the self-insured health plan which is included in accrued loss reserves on the Company's consolidated balance sheets. This reserve includes both unpaid claims and an estimate of claims incurred but not reported, based on historical claims and payment experience. Historically, the reserves have been sufficient to provide for claims payments. Changes in actual claims experience or payment patterns could cause the reserve to change, but the Company does not believe it is reasonably likely that the reserve level will materially change in the near future.

The remaining U.S. subsidiary is covered under a fully insured group health plan. Employees of the Company's foreign subsidiaries are insured under separate health plans. No reserves are necessary for these fully-insured health plans.

Revenue Recognition

Revenue Recognition - Revenue is generally recognized on sales at the point in time when persuasive evidence of an arrangement exists, the price is fixed or determinable, the product has been delivered or services have been rendered and there is a reasonable assurance of collection of the sales proceeds. The Company generally obtains purchase authorizations from its customers for a specified amount of products at a specified price with specified delivery terms. A significant portion of the Company's equipment sales represents equipment produced in the Company's plants under short-term contracts for a specific customer project or equipment designed to meet a customer's specific requirements. Most of the equipment sold by the Company is based on standard configurations, some of which are modified to meet customer needs or specifications. The Company provides customers with technical design and performance specifications and performs pre-shipment testing to ensure the equipment performs according to design specifications, regardless of whether the Company provides installation services in addition to selling the equipment.

Certain contracts include terms and conditions pursuant to which the Company recognizes revenues upon completion of equipment production, which is subsequently stored at the Company's plant at the customer's request. Revenue is recorded on such contracts upon the customer's assumption of title and risk of ownership and when collectability is reasonably assured. In addition, there must be a fixed schedule of delivery of the goods consistent with the customer's business practices, the Company must not have retained any specific performance obligations such that the earnings process is not complete and the goods must have been segregated from the Company's inventory prior to revenue recognition.

The Company has certain sales accounted for as multiple-element arrangements, whereby revenue attributable to the sale of a product is recognized when the product is shipped, and the revenue attributable to services provided with respect to the product (such as installation services) is recognized when the service is performed. Consideration is allocated to deliverables using the relative selling price method using vendor specific objective evidence, if it exists. Otherwise, the Company uses third-party evidence of selling price or the Company's best estimate of the selling price for the deliverables. The Company evaluates sales with multiple deliverable elements (such as an agreement to deliver equipment and related installation services) to determine whether revenue related to individual elements should be recognized separately, or as a combined unit. In addition to the previously mentioned general revenue recognition criteria, the Company only recognizes revenue on individual delivered elements when there is objective and reliable evidence that the delivered element has a determinable value to the customer on a standalone basis and there is no right of return.

The Company has certain sales accounted for under the percentage of completion method using the ratio of costs incurred to estimated total costs. Revenue, in an amount equal to cost incurred, is recognized until there is sufficient information to determine the estimated profit on the project with a reasonable level of certainty. The factors considered in this evaluation include the stage of design completion, the stage of equipment manufacturing completion, the state of construction completion, the status of outstanding subcontracts, certainty of quantities of labor and materials, certainty of schedule and the relationship with the customer.

The Company presents in the consolidated statements of income any taxes assessed by a governmental authority that are directly imposed on revenue-producing transactions between the Company and its customers, such as sales, use, value-added and some excise taxes, on a net (excluded from revenue) basis.

Advertising Expense

Advertising Expense - The cost of advertising is expensed as incurred. The Company incurred $3,793, $4,045, and $4,231 in advertising costs during 2017, 2016 and 2015, respectively, which is included in selling, general and administrative expenses.

Income Taxes

Income Taxes - Income taxes are based on pre-tax financial accounting income. Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax bases of assets and liabilities and their reported amounts. The Company periodically assesses the need to establish valuation allowances against its deferred tax assets to the extent the Company no longer believes it is more likely than not that the tax assets will be fully utilized.

The Company evaluates a tax position to determine whether it is more likely than not that the tax position will be sustained upon examination, based upon the technical merits of the position. A tax position that meets the more-likely-than-not recognition threshold is subject to a measurement assessment to determine the amount of benefit to recognize and the appropriate reserve to establish, if any. If a tax position does not meet the more-likely-than-not recognition threshold, no benefit is recognized. The Company is periodically audited by U.S. federal and state as well as foreign tax authorities. While it is often difficult to predict final outcome or timing of resolution of any particular tax matter, the Company believes its reserve for uncertain tax positions is adequate to reduce the uncertain positions to the greatest amount of benefit that is more likely than not realizable.

Product Warranty Reserve

Product Warranty Reserve - The Company accrues for the estimated cost of product warranties at the time revenue is recognized. Warranty obligations by product line or model are evaluated based on historical warranty claims experience. For equipment, the Company's standard product warranty terms generally include post-sales support and repairs of products at no additional charge for periods ranging from three months to two years or up to a specified number of hours of operation. For parts from component suppliers, the Company relies on the original manufacturer's warranty that accompanies those parts. Generally, Company fabricated parts are not covered by specific warranty terms. Although failure of fabricated parts due to material or workmanship is rare, if it occurs, the Company's policy is to replace fabricated parts at no additional charge.

The Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of our component suppliers. Estimated warranty obligations are based upon warranty terms, product failure rates, repair costs and current period machine shipments. If actual product failure rates, repair costs, service delivery costs or post-sales support costs differ from our estimates, revisions to the estimated warranty liability may be required.

Pension and Retirement Plans

Pension and Retirement Plans - The determination of obligations and expenses under the Company's pension plan is dependent on the Company's selection of certain assumptions used by independent actuaries in calculating such amounts. Those assumptions are described in Note 12, Pension and Retirement Plans and include among others, the discount rate, expected return on plan assets and the expected mortality rates. In accordance with U.S. generally accepted accounting principles, actual results that differ from assumptions are accumulated and amortized over future periods and, therefore, generally affect the recognized expense in such periods. Significant differences in actual experience or significant changes in the assumptions used may materially affect the pension obligations and future expenses.

The Company recognizes the overfunded or underfunded status of its pension plan as an asset or liability. Actuarial gains and losses, amortization of prior service cost (credit) and amortization of transition obligations are recognized through other comprehensive income (loss) in the year in which the changes occur. The Company measures the funded status of its pension plan as of the date of the Company's fiscal year-end.

Stock-based Compensation

Stock-based Compensation -The Company recognizes the cost of employee services received in exchange for equity awards in the consolidated financial statements based on the grant date calculated fair value of the awards. The Company recognizes stock-based compensation expense over the period during which an employee is required to provide service in exchange for the award (the vesting period). The Company's equity awards are further described in Note 16, Shareholders' Equity.

Earnings Per Share

Earnings Per Share -Basic earnings per share is based on the weighted average number of common shares outstanding and diluted earnings per share includes potential dilutive effects of restricted stock units and shares held in the Company's supplemental executive retirement plan.

The following table sets forth a reconciliation of the number of shares used in the computation of basic and diluted earnings per share:

	Year Ended December 31
	2017		2016		2015
Denominator:
Denominator for basic earnings per share		23,025		22,992		22,934
Effect of dilutive securities:
Restricted stock units		96		85		123
Supplemental executive retirement plan		63		65		63
Denominator for diluted earnings per share		23,184		23,142		23,120

Derivatives and Hedging Activities

Derivatives and Hedging Activities - The Company recognizes all derivatives in the consolidated balance sheets at their fair value. Derivatives that are not hedges are adjusted to fair value through income. If the derivative is a hedge, depending on the nature of the hedge, changes in the fair value of derivatives are either offset against the change in fair value of assets, liabilities, or firm commitments through income or recognized in other comprehensive income until the hedged item is recognized in income. The ineffective portion of a derivative's change in fair value is immediately recognized in income. From time to time, the Company's foreign subsidiaries enter into foreign currency exchange contracts to mitigate exposure to fluctuation in currency exchange rates. See Note 13, Derivative Financial Instruments, regarding foreign exchange contracts outstanding at December 31, 2017 and 2016.

Shipping and Handling Fees and Cost

Shipping and Handling Fees and Cost - The Company records revenues earned for shipping and handling as revenue, while the cost of shipping and handling is classified as cost of sales.

Business Combinations

Business Combinations - The Company accounts for business combinations using the acquisition method. Accordingly, intangible assets are recorded apart from goodwill if they arise from contractual or legal rights or if they are separable from goodwill. Related third-party acquisition costs are expensed as incurred and contingent consideration is booked at its fair value as part of the purchase price. See Note 20, Business Combinations, regarding acquisitions completed by the Company in the years ended December 31, 2017 and 2016.

Subsequent Events Review

Subsequent Events Review - Management has evaluated events occurring between December 31, 2017 and the date these consolidated financial statements were filed with the Securities and Exchange Commission for proper recording or disclosure therein.

Recent Accounting Pronouncements

Recent Accounting Pronouncements -In May 2014, the Financial Accounting Standards Board ('FASB") issued Accounting Standards Update ("ASU") No. 2014-09, "Revenue from Contracts with Customers", which supersedes existing revenue guidance under U.S. GAAP. The standard's core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The implementation of this new standard will require companies to use more judgment and to make more estimates than under current guidance and to expand their disclosures to include information regarding contract assets and liabilities as well as a more disaggregated view of revenue. The standard, as amended, is effective for public companies for annual periods beginning after December 15, 2017. The Company adopted the new standard effective January 1, 2018 using the modified retrospective transition method and will expand its disclosures in the first quarter 2018 consolidated financial statements to comply with the disclosure provisions of the new rule. The Company does not expect the adoption of the standard to have a material impact on its financial position, results of operations or cash flows.

In January 2016, the FASB issued ASU No. 2016-01, "Financial Instruments - Overall (Subtopic 825-10)", which requires, among other things, equity investments with readily determinable fair values, except those accounted for under the equity method of accounting or those that result in consolidation of the investee, to be measured at fair value with changes in fair value recognized in net income. The standard is effective for public companies in fiscal years beginning after December 15, 2017, and the Company adopted the standard effective January 1, 2018. The Company does not expect the adoption of this standard to have a material impact on the Company's financial position, cash flows or results of operations.

In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)", which significantly changes the accounting for operating leases by lessees. The accounting applied by lessors is largely unchanged from that applied under previous guidance. The new guidance requires lessees to recognize lease assets and lease liabilities in the balance sheet, initially measured at the present value of the lease payments, for leases which were classified as operating leases under previous guidance. Lease cost included in the statement of income will be calculated so that the cost of the lease is allocated over the lease term, generally on a straight-line basis. Lessees may make an accounting policy election to exclude leases with a term of 12 months or less from the requirement to record related assets and liabilities. The new standard is effective for public companies for fiscal years beginning after December 15, 2018. The Company plans to adopt the new standard effective January 1, 2019. The Company does not expect the adoption of this standard to have a material impact on its results of operations or cash flows; however, the Company has not determined the impact the adoption of this new standard will have on its financial position.

In March 2016, the FASB issued ASU No. 2016-08, "Revenue from Contracts with Customers (Topic 606)", which does not change the core principles of ASU No. 2014-09 discussed above, but rather clarifies the implementation guidance in order to eliminate the potential for diversity in practice arising from inconsistent application of the principal versus agent guidance. Under the new guidance, when an entity determines it is a principal in a transaction, the entity recognizes revenue in the gross amount of consideration; however, in transactions where an entity determines it is an agent, the entity recognizes revenue in the amount of any fee or commission to which it expects to be entitled. The standard is effective for public companies for annual periods beginning after December 15, 2017. The Company adopted the new standard effective January 1, 2018. The Company does not expect the adoption of this new standard to have a material impact on the Company's financial position, results of operations or cash flows.

In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments". The standard changes how credit losses are measured for most financial assets and certain other instruments that currently are not measured through net income. The standard will require an expected loss model for instruments measured at amortized cost as opposed to the current incurred loss approach. In valuing available for sale debt securities, allowances will be required to be recorded, rather than the current approach of reducing the carrying amount, for other than temporary impairments. A cumulative adjustment to retained earnings is to be recorded as of the beginning of the period of adoption to reflect the impact of applying the provisions of the standard. The standard is effective for public companies for periods beginning after December 15, 2019 and the Company expects to adopt the new standard as of January 1, 2020. The Company has not yet determined what impact, if any, the adoption of this new standard will have on the Company's financial position results of operations or cash flows.

In August 2016, the FASB issued ASU No. 2016-15, "Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force)" which clarifies how certain cash receipts and cash payments should be presented on the statement of cash flows. The statement also addresses how the predominance principle should be applied when cash payments have aspects of more than one class of cash flows. The standard is effective for public companies in fiscal years beginning after December 15, 2017, and the Company adopted the standard effective January 1, 2018. The Company does not expect the adoption of this new standard to have a material impact on the Company's consolidated statements of cash flows.

In October 2016, the FASB issued ASU No. 2016-16, "Income Taxes (Topic 740), Intra-Entity Transfers of Assets Other Than Inventory" which requires companies to account for the income tax effects of intercompany sales and transfers of assets other than inventory, such as intangible assets, when the transfer occurs. This is a change from current guidance, which requires companies to defer the income tax effects of intercompany transfers of assets until the asset has been sold to an outside party or otherwise recognized by being depreciated, amortized, or impaired. The new guidance will require companies to defer the income tax effects of only intercompany transfers of inventory. The standard is effective for public companies in fiscal years beginning after December 15, 2017. The Company adopted the new standard effective January 1, 2018. The Company does not expect the application of this standard to have a material impact on the Company's financial position, results of operations or cash flows.

In January 2017, the FASB issued ASU No. 2017-01, "Business Combinations (Topic 805), Clarifying the Definition of a Business," which provides additional guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The standard is effective for public companies for annual or interim periods beginning after December 15, 2017. The Company adopted the new standard effective January 1, 2018. The Company does not expect the application of this standard to have a material impact on its financial position, results of operations or cash flows.

In January 2017, the FASB issued ASU No. 2017-04, "Intangibles-Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment," which eliminates Step 2 from the goodwill impairment test for public companies.  Previously, Step 2 measured a goodwill impairment loss by comparing the implied fair value of a reporting unit's goodwill with the carrying amount of that goodwill. The new guidance stipulates that an entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge would be recognized for the amount by which the carrying amount exceeds the reporting unit's fair value, up to the amount of goodwill allocated to the reporting unit. The standard is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019 with early adoption permitted. The Company elected to adopt this standard as of December 31, 2017. The application of this standard did not have a material impact on the Company's financial position, results of operations or cash flows.

In August 2017, the FASB issued ASU No. 2017-12, "Derivatives and Hedging (Topic 815), Targeted Improvements to Hedging Activities", to improve the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements. The new guidance is effective for public companies for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years with early adoption permitted in any interim period after its issuance. The Company plans to adopt the new standard effective January 1, 2019. The Company does not expect the application of this standard to have a material impact on its financial position, results of operations or cash flows.
