PART I

Item 1. Business

Founded in 1959, Generac Holdings Inc. (the Company or Generac) is a leading global designer and manufacturer of a wide range of power generation equipment and other engine powered products serving the residential, light commercial and industrial markets. Power generation is our primary focus, which differentiates us from our main competitors that also have broad operations outside of the power equipment market. As the only significant market participant focused predominantly on these products, we have one of the leading market positions in the power equipment market in North America and an expanding presence internationally. We believe we have one of the widest ranges of products in the marketplace, including residential, commercial and industrial standby generators; as well as portable and mobile generators used in a variety of applications. Other engine powered products that we design and manufacture include light towers which provide temporary lighting for various end markets; commercial and industrial mobile heaters and pumps used in the oil & gas, construction and other industrial markets; and a broad product line of outdoor power equipment for residential and commercial use.

1

We design, manufacture, source and modify engines, alternators, transfer switches and other components necessary for our products, which are fueled by natural gas, liquid propane, gasoline, diesel and Bi-Fuel™. Our products are available globally through a broad network of independent dealers, distributors, retailers, wholesalers and equipment rental companies under a variety of brand names. We also sell direct to certain national and regional account customers, as well as to individual consumers, that are the end users of our products.

We have a significant market share in the residential and light commercial markets for automatic standby generators, which we believe remain under-penetrated in the marketplace. We also have a leading market position for portable generators used in residential, light construction and recreational applications. We believe that our leading market position is largely attributable to our strategy of providing a broad product line of high-quality, innovative and affordable products through our extensive and multi-layered distribution network to whom we offer comprehensive support and programs from the factory. In addition, we are a leading provider of light towers, mobile generators, flameless heaters, outdoor power equipment and industrial diesel generators ranging in sizes up to 3,250kW.

Over the years, we have executed a number of acquisitions that support our strategic plan. A summary of the recent acquisitions can be found in Note 1, “Description of Business,” to the consolidated financial statements in Item 8 of this Annual Report on Form 10-K.

Reportable Segments

The Company has two reportable segments for financial reporting purposes – Domestic and International. The Domestic segment includes the legacy Generac business and the impact of acquisitions that are based in the United States, all of which have revenues that are substantially derived from the U.S. and Canada. The International segment includes the Ottomotores, Tower Light, Pramac and Motortech acquisitions, all of which have revenues that are substantially derived from outside the U.S. and Canada. Both reportable segments design and manufacture a wide range of power generation equipment and other engine powered products, which are discussed in further detail below in the context of our product classes. Refer to Note 6, “Segment Reporting,” to the consolidated financial statements in Item 8 of this Annual Report on Form 10-K for further information.

Products

We design and manufacture stationary, portable and mobile generators with single-engine outputs ranging between 800W and 3,250kW. We have the ability to expand the power range for certain stationary generator solutions to much larger multi-megawatt systems through an integrated paralleling configuration called Modular Power Systems (MPS). Other engine powered products that we design and manufacture include light towers, mobile heaters, power washers and water pumps, along with a broad line of outdoor power equipment. We classify our products into three categories based on similar range of power output geared for varying end customer uses: Residential products, Commercial & Industrial (C&I) products and Other products. The following summary outlines our portfolio of products, including their key attributes and customer applications.

Residential Products

Our residential automatic standby generators range in output from 6kW to 60kW, with manufacturer's suggested retail prices (MSRPs) from approximately $1,949 to $16,199. These products operate on natural gas, liquid propane or diesel and are permanently installed with an automatic transfer switch, which we also manufacture. Air-cooled engine residential standby generators range in outputs from 6kW to 22kW, are available in steel and aluminum enclosures and serve as an emergency backup for small to medium-sized homes. Liquid-cooled engine generators serve as emergency backup for larger homes and small businesses and range in output from 22kW to 60kW. We also provide a cellular-based remote monitoring system for home standby generators called Mobile Link™, which allows our customers to check the status of their generator conveniently from a desktop PC, tablet computer or smartphone, and also provides the capability to receive maintenance and service alerts.

We provide a broad product line of portable and inverter generators that are fueled predominantly by gasoline, with certain models running on propane and diesel fuel, which range in size from 800W to 17.5kW. These products serve as an emergency home backup source of electricity and are also used for construction and recreational purposes. Our portable generators are targeted at homeowners, with price points ranging between the consumer value end of the market through the premium homeowner market; at professional contractors, starting at the value end through the premium contractor segment; and at the recreational market with our inverter product line. In addition, we offer manual transfer switches to supplement our portable generator product offering.

2

We provide a broad product line of engine driven power washers for residential and commercial use, fueled by gasoline, which range in pressure from 2,500 to 4,200 PSI. Additionally, we offer a product line of water pumps built to meet the water removal needs of homeowners, farmers, construction crews and other end-user applications.

Further, we provide a broad product line of outdoor power equipment that includes trimmer & brush mowers, log splitters, lawn & leaf vacuums, and chipper shredders for the property maintenance needs of larger-acreage residences, commercial properties, municipalities and farms. These products are largely sold in North America through catalogs, on-line, retail hardware stores and outdoor power equipment dealers primarily under the DR® brand name.

Residential products comprised 52.0%, 53.5% and 51.2%, respectively, of total net sales in 2017, 2016 and 2015.

Commercial & Industrial Products

We offer a full line of C&I generators fueled by diesel, natural gas, liquid propane and Bi-Fuel™. We believe we have one of the broadest product offerings in the industry with power outputs ranging from 10kW up to 3,250kW.

Our light-commercial standby generators include a full range of affordable systems from 22kW to 150kW and related transfer switches, providing three-phase power sufficient for most small and mid-sized businesses such as grocery stores, convenience stores, restaurants, gas stations, pharmacies, retail banks, small health care facilities and other small-footprint retail applications. Our light-commercial generators run on natural gas, liquid propane and diesel fuel.

We manufacture a broad product line of standard and configured stationary generators and related transfer switches for various industrial standby, continuous-duty and prime rated applications. Our single-engine industrial generators range in output from 10kW up to 3,250kW, which includes stationary and containerized packages, with our MPS technology extending our product range up to much larger multi-megawatt systems through an integrated paralleling configuration. We offer four fuel options for our industrial generators, including diesel, natural gas, liquid propane or Bi-Fuel™. Bi-Fuel™ generators operate on a combination of both diesel and natural gas to allow our customers the advantage of multiple fuel sources and extended run times. Our industrial standby generators are primarily used as emergency backup for larger applications in the healthcare, telecom, datacom, commercial office, municipal and manufacturing markets.

Our MPS technology combines the power of several smaller generators to produce the output of a larger generator, providing our customers with redundancy and scalability in a cost-effective manner. For larger industrial applications, our MPS products offer customers an efficient, affordable way to scale their standby power needs, and also offers superior reliability given its built-in redundancy which allows individual units to be taken off-line for routine maintenance while retaining coverage for critical circuits.

We provide a broad product line of light towers, mobile generators and mobile heaters, which provide temporary lighting, power and heat for various end markets, such as road and commercial construction, energy, mining, military and special events. We also manufacture commercial mobile pumps which utilize wet and dry-priming pump systems for a wide variety of wastewater applications.

The acquisition of Motortech in January 2017 added gaseous-engine control systems and accessories which are sold primarily to European gas-engine manufacturers and to aftermarket customers.

C&I products comprised 41.0%, 38.6% and 41.6% respectively, of total net sales in 2017, 2016 and 2015.

Other Products

Our “Other Products” category includes aftermarket service parts to our dealers, product accessories and proprietary engines to third-party original equipment manufacturers (OEMs).

Other products comprised 7.0%, 7.9% and 7.2%, respectively, of total net sales in 2017, 2016 and 2015.

Distribution Channels and Customers

We distribute our products through a variety of different distribution channels to increase awareness of our product categories and brands, and to ensure our products reach a broad customer base. This distribution network includes independent residential dealers, industrial distributors and dealers, national and regional retailers, e-commerce merchants, electrical and HVAC wholesalers (including certain private label arrangements), catalogs, equipment rental companies and equipment distributors. We also sell direct to certain national and regional account customers, as well as to individual consumers, who are the end users of our products.

3

We believe our distribution network is a competitive advantage that has strengthened over the years as a result of adding, expanding and developing the various distribution channels through which we sell our products. We offer a broad set of tools, programs and factory support to help our distribution partners be successful. Our network is well balanced with no customer providing more than 6% of our sales in 2017.

Our overall dealer network located in the United States, Canada and Latin America, is the industry's largest network of factory direct independent generator contractors in North America. We expanded our dealer network in recent years on a global basis with the acquisition of Pramac in March 2016, particularly in Europe, the Middle East and Asia/Pacific regions.

Our residential/light commercial dealer network sells, installs and services our residential and light commercial products to end users. We have increased our level of investment in recent years by focusing on a variety of initiatives to more effectively market and sell our home standby products and better align our dealer network with Generac.

Our industrial network consists of a combination of primary distributors as well as a support network of dealers serving the United States and Canada. The industrial distributors and dealers provide industrial and commercial end users with ongoing sales and product support. Our industrial distributors and dealers maintain the local relationships with commercial electrical contractors, specifying engineers and national account regional buying offices. Over the past several years, we have been expanding our dealer network globally through acquisitions and organic means, in order to expand our international sales opportunities.

Our retail distribution network includes thousands of locations across the globe and includes a variety of regional and national home improvement chains, retailers, clubs, buying groups and farm supply stores. These physical retail locations are supplemented by a growing presence of e-commerce retailers, along with a number of catalog retailers. This network primarily sells our residential standby, portable and light-commercial generators, as well as our other engine powered tools. The placement of our products at retail locations drives significant awareness for our brands and the automatic home standby product category.

Our wholesaler network distributes our residential and light-commercial generators, and consists of selling branches of both national and local distribution houses for electrical and HVAC products.

On a selective basis, we have established private label and licensing arrangements with third party partners to provide residential, light-commercial and industrial generators. These partners include leading home equipment, electrical equipment and construction machinery companies, each of which provides access to incremental channels of distribution for our products.

The distribution for our mobile products includes international, national, regional and specialty equipment rental companies, equipment distributors and construction companies, which primarily serve non-residential building construction, road construction, energy markets and special events. In addition, international acquisitions over the past several years have provided access to numerous independent distributors in over 150 countries.

We sell direct to certain national and regional account customers that are the end users of our products covering a number of end market verticals, including telecommunication, retail, banking, convenience stores, grocery stores and other light commercial applications. Additionally, our residential products are sold direct to individual consumers, who are the end users of the product.

Business Strategy
 

We have been executing on our “Powering Ahead” strategic plan, which serves as the framework for the significant investments we have made to capitalize on the long-term growth prospects of Generac. As we continue to move the Powering Ahead plan into the future, we are focused on a number of initiatives that are driven by the same four key objectives:

Growing the residential standby generator market. As the leader in the home standby generator market, it is incumbent upon us to continue to drive growth and increase the penetration rate of these products in households across the United States and Canada. Central to this strategy is to increase the awareness, availability and affordability of home standby generators. Ongoing power outage activity, combined with expanding our residential/light commercial dealer base and overall distribution in affected regions, are key drivers in elevating the awareness of home standby generators over the long term. We intend to continue to supplement these key growth drivers by focusing on a variety of strategic initiatives targeted toward generating more sales leads, improving close rates and reducing the total overall cost of a home standby system. In addition, we intend to continue to focus on innovation in this growing product category and introduce new products into the marketplace. With only approximately 4.0% penetration of the addressable market of homes in the United States (which we define as single-family detached, owner-occupied households with a home value of over $100,000, as defined by the U.S. Census Bureau's 2015 American Housing Survey for the United States), we believe there are opportunities to further penetrate the residential standby generator market.

4

Gaining commercial and industrial market share. Our growth strategy for commercial and industrial power generation products is focused on incremental market share gains. Key to this objective are efforts to leverage our expanding platform of diesel and natural gas offerings by better optimizing our industrial distribution partners’ capabilities to market, sell and support these products. Specifically, we continue to pursue certain initiatives to expand our distributors’ interactions with engineering firms and electrical contractors responsible for specifying and selecting our products within C&I power generation applications. We are also committed to a number of sales process initiatives and go-to-market strategies to increase market visibility and improve the overall specification rates for our products which should increase quoting activity and close rates for our industrial distributors.

Lead with gas power generation products. We will attempt to gain incremental market share within commercial and industrial markets through our leading position in the growing market for cleaner burning, more cost effective natural gas fueled standby power solutions. While still a smaller portion of the overall C&I market, we believe demand for these products continues to increase at a faster rate than traditional diesel fueled generators as a result of their lower capital investment and operating costs. We also intend to explore new gaseous generator related market opportunities, including increasing our product capabilities for continuous-duty and prime rated applications, by leveraging our deep technical capabilities for gaseous-fueled products, leading position for natural gas standby generators and growing market acceptance for these products. As part of this strategy, we plan to continue to expand our natural gas product offering into larger power nodes to take advantage of the continuing shift from diesel to natural gas generators.

Expanding global presence. We have increased our revenues shipped outside the U.S. and Canada in recent years, with sales outside this region accounting for approximately 22% of our revenues during 2017, as compared to approximately 20% and 10% in 2016 and 2015, respectively. This increase is largely the result of acquisitions made that comprise our International segment – Ottomotores, Tower Light, Pramac and Motortech. These businesses have significantly increased our global presence by adding product, manufacturing and distribution capabilities that serve local markets around the world, and have resulted in us becoming a leading global player in the markets for backup power and mobile power equipment. As we look forward, we intend to leverage our increased international footprint attained from these acquisitions to serve the over $13 billion annual market for power generation equipment outside the U.S. and Canada. We also intend to improve the profit margins of our International segment by executing on several revenue and cost synergies, and driving organic growth in existing markets with additional investment and focus, including the expanding opportunity for global gaseous-fueled products. We will continue to evaluate other opportunities to expand into additional regions of the world through both organic initiatives and potential acquisitions.

We believe the investments we have made to date, due in part to our Powering Ahead strategy, have helped to capitalize on the macro, secular growth drivers for our business and are an important part of our efforts to diversify and globalize our business. See “Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations – Business Drivers and Trends” for additional drivers that influence demand for our products and other trends affecting the markets that we serve.

Manufacturing

We operate numerous manufacturing plants, distribution facilities and inventory warehouses located throughout the world. We maintain inventory warehouses in the United States that accommodate material storage and rapid response requirements of our customers. See “Item 2 – Properties” for additional details regarding the locations and activities of our principal operations.

In recent years, we have added manufacturing capacity through investments in automation, improved utilization and the expansion of our manufacturing footprint through organic means as well as through acquisitions. We believe we have sufficient capacity to achieve our business goals for the near-to-intermediate term.

Research and Development

Our primary focus on power generation equipment and other engine powered products drives technological innovation, specialized engineering and manufacturing competencies. Research and development (R&D) is a core competency and includes a staff of over 350 engineers working on numerous projects. Our total R&D expense was $42.9 million, $37.2 million and $32.9 million for the years ended December 31, 2017, 2016 and 2015, respectively. R&D is conducted at various facilities worldwide, including a recent expansion of our advanced engineering labs at our corporate headquarters and the addition of a Chinese technology center in Suzhou, China. These activities are focused on developing new technologies and product enhancements as well as maintaining product competitiveness by improving manufacturing costs, safety characteristics, reliability and performance while ensuring compliance with regulatory standards. We have over 30 years of experience using natural gas engines and have developed specific expertise with fuel systems and emissions technology. In the residential and light commercial markets, we have developed proprietary engines, cooling packages, controls, fuel systems and emissions systems. We believe that our expertise in engine powered equipment gives us the capability to develop new products that will allow continued diversification in our end markets.

5

Intellectual Property

We are committed to research and development, and we rely on a combination of patents and trademarks to establish and protect our proprietary rights. Our patents protect certain features and technologies we have developed for use in our products including fuel systems, air flow, electronics and controls, noise reduction and air-cooled engines. We believe the existence of these patents and trademarks, along with our ongoing processes to register additional patents and trademarks, protect our intellectual property rights and enhance our competitive position. We also use proprietary manufacturing processes that require customized equipment.

Suppliers of Raw Materials

Our primary raw material inputs are steel, copper and aluminum, all of which are purchased from third parties and, in many cases, as part of machined or manufactured components. We have developed an extensive network of reliable suppliers in the United States and internationally. Our Strategic Global Sourcing (SGS) function continuously evaluates the quality and cost structure of our products and assesses the capabilities of our supply chain. Components are sourced accordingly based on this evaluation. Our supplier quality engineers conduct on-site audits of major supply chain partners and help to maintain the reliability of critical sourced components.

Competition

The market for power generation equipment and other engine powered products is competitive. We face competition from a variety of large diversified industrial companies as well as smaller generator manufacturers, along with mobile equipment and engine powered tools providers, both domestic and internationally. However, specifically in the generator market, most of the traditional participants compete on a more specialized basis, focused on specific applications within their larger diversified product mix. We are the only significant market participant with a primary focus on power equipment with a core emphasis on standby, portable and mobile generators with broad capabilities across the residential, light-commercial and industrial markets. We believe that our engineering capabilities and core focus on generators provide us with manufacturing flexibility and enables us to maintain a first-mover advantage over our competition for product innovation. We also believe our broad product offering, diverse distribution model and strong factory support provide additional advantages as well.

A summary of the primary competitors across our main product classes are as follows:

Residential products – Kohler, Briggs & Stratton, Cummins, Honda, Champion, Techtronics International, Husqvarna and Ariens, along with a number of smaller domestic and foreign competitors; certain of which also have broad operations in other manufacturing businesses.

C&I products – Caterpillar, Cummins, Kohler, MTU, Stemac, IGSA, Wacker, MultiQuip, Terex, Doosan, Briggs & Stratton (Allmand), Atlas Copco and Himonisa; certain of which focus on the market for diesel generators as they are also diesel engine manufacturers. Also, we compete against other regional packagers that serve local markets throughout the world.

In a continuously evolving market, we believe our scale and broad capabilities make us well positioned to remain competitive. We compete primarily on the basis of brand reputation, quality, reliability, pricing, innovative features, breadth of product offering, product availability and factory support.

Item 1A. Risk Factors

You should carefully consider the following risks. These risks could materially affect our business, results of operations or financial condition, cause the trading price of our common stock to decline materially or cause our actual results to differ materially from those expected or those expressed in any forward-looking statements made by us. These risks are not exclusive, and additional risks to which we are subject include, but are not limited to, the factors mentioned under “Forward-Looking Statements” and the risks of our businesses described elsewhere in this Annual Report.

Risk factors related to our business and industry

Demand for the majority of our products is significantly affected by unpredictable power-outage activity that can lead to substantial variations in, and uncertainties regarding, our financial results from period to period.

Sales of our products are subject to consumer buying patterns, and demand for the majority of our products is affected by power outage events caused by thunderstorms, hurricanes, ice storms, blackouts and other power grid reliability issues. The impact of these outage events on our sales can vary depending on the location, frequency and severity of the outages. Sustained periods without major power disruptions can lead to reduced consumer awareness of the benefits of standby and portable generator products and can result in reduced sales growth rates and excess inventory. There are smaller, more localized power outages that occur frequently that drive a baseline level of demand for back-up power solutions. The lack of major power-outage events and fluctuations to the baseline levels of power-outage activity are part of managing our business, and these fluctuations could have an adverse effect on our net sales and profits. Despite their unpredictable nature, we believe power disruptions create awareness and accelerate adoption for our home standby products.

Demand for our products is significantly affected by durable goods spending by consumers and businesses, and other macroeconomic conditions.

Our business is affected by general economic conditions, and uncertainty or adverse changes such as the prolonged downturn in U.S. residential investment and the impact of more stringent credit standards could lead to a decline in demand for our products and pressure to reduce our prices. Our sales of light-commercial and industrial generators are affected by conditions in the non-residential construction sector and by the capital investment trends for small and large businesses and municipalities. If these businesses and municipalities cannot access credit markets or do not utilize discretionary funds to purchase our products as a result of the economy or other factors, our business could suffer and our ability to realize benefits from our strategy of increasing sales in the light-commercial and industrial sectors through, among other things, our focus on innovation and product development, including natural gas engine and modular technology, could be adversely affected. In addition, consumer confidence and home remodeling expenditures have a significant impact on sales of our residential products, and prolonged periods of weakness in consumer durable goods spending could have a material impact on our business. Typically, we do not have contracts with our customers which call for committed volume, and we cannot guarantee that our current customers will continue to purchase our products at the same level, if at all. If general economic conditions or consumer confidence were to worsen, or if the non-residential construction sector or rate of capital investments were to decline, our net sales and profits would likely be adversely affected. Additionally, timing of capital spending by our national account customers can vary from quarter-to-quarter based on capital availability and internal capital spending budgets.

8

Decreases in the availability and quality, or increases in the cost, of raw materials and key components we use could materially reduce our earnings.

The principal raw materials that we use to produce our products are steel, copper and aluminum. We also source a significant number of component parts from third parties that we utilize to manufacture our products. The prices of those raw materials and components are susceptible to significant fluctuations due to trends in supply and demand, transportation costs, government regulations and tariffs, price controls, economic conditions and other unforeseen circumstances beyond our control. We do not have long-term supply contracts in place to ensure the raw materials and components we use are available in necessary amounts or at fixed prices. If we are unable to mitigate raw material or component price increases through product design improvements, price increases to our customers, manufacturing productivity improvements, or hedging transactions, our profitability could be adversely affected. Also, our ability to continue to obtain quality materials and components is subject to the continued reliability and viability of our suppliers, including in some cases, suppliers who are the sole source of certain important components. If we are unable to obtain adequate, cost efficient or timely deliveries of required raw materials and components, we may be unable to manufacture sufficient quantities of products on a timely basis. This could cause us to lose sales, incur additional costs, delay new product introductions or suffer harm to our reputation.

The industry in which we compete is highly competitive, and our failure to compete successfully could adversely affect our results of operations and financial condition.

We operate in markets that are highly competitive. Some of our competitors have established brands and are larger in size or are divisions of large diversified companies which have substantially greater financial resources than we do. Some of our competitors may be willing to reduce prices and accept lower margins in order to compete with us. In addition, we could face new competition from large international or domestic companies with established industrial brands that enter our end markets. Demand for our products may also be affected by our ability to respond to changes in design and functionality, to respond to downward pricing pressure, and to provide shorter lead times for our products than our competitors. If we are unable to respond successfully to these competitive pressures, we could lose market share, which could have an adverse impact on our results. For further information, see “Item 1—Business—Competition”.

Our industry is subject to technological change, and our failure to continue developing new and improved products and to bring these products rapidly to market could have an adverse impact on our business.

New products, or refinements and improvements of existing products, may have technical failures, delayed introductions, higher than expected production costs or may not be well accepted by our customers. If we are not able to anticipate, identify, develop and market high quality products in line with technological advancements that respond to changes in customer preferences, demand for our products could decline and our operating results could be adversely affected.

We rely on independent dealers and distribution partners, and the loss of these dealers and distribution partners, or of any of our sales arrangements with significant private label, national, retail or equipment rental customers, would adversely affect our business.

In addition to our direct sales force and manufacturer sales representatives, we depend on the services of independent distributors and dealers to sell our products and provide service and aftermarket support to our end customers. We also rely upon our distribution channels to drive awareness for our product categories and our brands. In addition, we sell our products to end users through private label arrangements with leading home equipment, electrical equipment and construction machinery companies; arrangements with top retailers and equipment rental companies; and our direct national accounts with telecommunications and industrial customers. Our distribution agreements and any contracts we have with large national, retail and other customers are typically not exclusive, and many of the distributors with whom we do business offer competitors’ products and services. Impairment of our relationships with our distributors, dealers or large customers, loss of a substantial number of these distributors or dealers or of one or more large customers, or an increase in our distributors' or dealers' sales of our competitors' products to our customers or of our large customers' purchases of our competitors' products could materially reduce our sales and profits. Also, our ability to successfully realize our growth strategy is dependent in part on our ability to identify, attract and retain new distributors at all layers of our distribution platform, and we cannot be certain that we will be successful in these efforts. For further information, see “Item 1—Business—Distribution Channels and Customers”.

Our business could be negatively impacted if we fail to adequately protect our intellectual property rights or if third parties claim that we are in violation of their intellectual property rights.

We consider our intellectual property rights to be important assets, and seek to protect them through a combination of patent, trademark, copyright and trade secret laws, as well as licensing and confidentiality agreements. These protections may not be adequate to prevent third parties from using our intellectual property without our authorization, breaching any confidentiality agreements with us, copying or reverse engineering our products, or developing and marketing products that are substantially equivalent to or superior to our own. The unauthorized use of our intellectual property by others could reduce our competitive advantage and harm our business. Not only are intellectual property-related proceedings burdensome and costly, but they could span years to resolve and we might not ultimately prevail. We cannot guarantee that any patents, issued or pending, will provide us with any competitive advantage or will not be challenged by third parties. Moreover, the expiration of our patents may lead to increased competition with respect to certain products.

In addition, we cannot be certain that we do not or will not infringe third parties' intellectual property rights. Any such claim, even if it is without merit, may be expensive and time-consuming to defend, subject us to damages, cause us to cease making, using or selling certain products that incorporate the disputed intellectual property, require us to redesign our products, divert management time and attention, and/or require us to enter into costly royalty or licensing arrangements.

Our operations are subject to various environmental, health and safety laws and regulations, and non-compliance with or liabilities under such laws and regulations could result in substantial costs, fines, sanctions and claims.

Our operations are subject to a variety of foreign, federal, state and local environmental, health and safety laws and regulations including those governing, among other things, emissions to air; discharges to water; noise; and the generation, handling, storage, transportation, treatment and disposal of waste and other materials. In addition, under federal and state environmental laws, we could be required to investigate, remediate and/or monitor the effects of the release or disposal of materials both at sites associated with past and present operations and at third-party sites where wastes generated by our operations were disposed. This liability may be imposed retroactively and whether or not we caused, or had any knowledge of, the existence of these materials and may result in our paying more than our fair share of the related costs. We could also be subject to a recall action by regulatory authorities. Violations of or liabilities under such laws and regulations could result in substantial costs, fines and civil or criminal proceedings or personal injury and workers' compensation claims.

Our products are subject to substantial government regulation.

Our products are subject to extensive statutory and regulatory requirements governing, among other things, emissions and noise, including standards imposed by the EPA, CARB and other regulatory agencies around the world. These laws are constantly evolving and many are becoming increasingly stringent. Changes in applicable laws or regulations, or in the enforcement thereof, could require us to redesign our products and could adversely affect our business or financial condition in the future. Developing and marketing products to meet such new requirements could result in substantial additional costs that may be difficult to recover in some markets. In some cases, we may be required to modify our products or develop new products to comply with new regulations, particularly those relating to air emissions and carbon monoxide. Typically, additional costs associated with significant compliance modifications are passed on to the market. While we have been able to meet previous deadlines and requirements, failure to comply with other existing and future regulatory standards could adversely affect our position in the markets we serve.

We may incur costs and liabilities as a result of product liability claims.

We face a risk of exposure to product liability claims in the event that the use of our products is alleged to have resulted in injury or other damage. Although we currently maintain product liability insurance coverage, we may not be able to obtain such insurance on acceptable terms in the future, if at all, or obtain insurance that will provide adequate coverage against potential claims. Product liability claims can be expensive to defend and can divert the attention of management and other personnel for long periods of time, regardless of the ultimate outcome. A significant unsuccessful product liability defense could have a material adverse effect on our financial condition and results of operations. In addition, we believe our business depends on the strong brand reputation we have developed. If our reputation is damaged, we may face difficulty in maintaining our market share and pricing with respect to some of our products, which could reduce our sales and profitability.

The loss of any key members of our senior management team or key employees could disrupt our operations and harm our business.

Our success depends, in part, on the efforts of certain key individuals, including the members of our senior management team, who have significant experience in the power products industry. If, for any reason, our senior executives do not continue to be active in management, or if our key employees leave our company, our business, financial condition or results of operations could be adversely affected. Failure to continue to attract these individuals at reasonable compensation levels could have a material adverse effect on our business, liquidity and results of operations. Although we do not anticipate that we will have to replace any of these individuals in the near future, the loss of the services of any of our key employees could disrupt our operations and have a material adverse effect on our business.

10

Disruptions caused by labor disputes or organized labor activities could harm our business.

We may from time to time experience union organizing activities in our non-union facilities. Disputes with the current labor union or new union organizing activities could lead to work slowdowns or stoppages and make it difficult or impossible for us to meet scheduled delivery times for product shipments to our customers, which could result in loss of business. In addition, union activity could result in higher labor costs, which could harm our financial condition, results of operations and competitive position. A work stoppage or limitations on production at our facilities for any reason could have an adverse effect on our business, results of operations and financial condition. In addition, many of our suppliers have unionized work forces. Strikes or work stoppages experienced by our customers or suppliers could have an adverse effect on our business, results of operations and financial condition.

We may experience material disruptions to our manufacturing operations.

While we seek to operate our facilities in compliance with applicable rules and regulations and take measures to minimize the risks of disruption at our facilities, a material disruption at one of our manufacturing facilities could prevent us from meeting customer demand, reduce our sales and/or negatively impact our financial results. Any of our manufacturing facilities, or any of our equipment within an otherwise operational facility, could cease operations unexpectedly due to a number of events, including:

● equipment or information technology infrastructure failure;

● disruptions in the transportation infrastructure including roads, bridges, railroad tracks and container ports;

● fires, floods, tornados, earthquakes, or other catastrophes; and

● other operational problems.

In addition, a significant portion of our manufacturing and production facilities are located in Wisconsin within a 100-mile radius of each other. We could experience prolonged periods of reduced production due to unforeseen events occurring in or around our manufacturing facilities in Wisconsin. In the event of a business interruption at our facilities, in particular our Wisconsin facilities, we may be unable to shift manufacturing capabilities to alternate locations, accept materials from suppliers or meet customer shipment needs, among other severe consequences. Such an event could have a material and adverse impact on our financial condition and results of our operations.

A significant portion of our purchased components are sourced in foreign countries, exposing us to additional risks that may not exist in the United States.

We source a significant portion of our purchased components overseas, primarily in Asia and Europe. Our international sourcing subjects us to a number of potential risks in addition to the risks associated with third-party sourcing generally. Such risks include:

● inflation or changes in political and economic conditions;

● unstable regulatory environments;

● changes in import and export duties;

● domestic and foreign customs and tariffs;

● currency rate fluctuations;

● trade restrictions;

● labor unrest;

● logistical challenges, including extended container port congestion;

● communications challenges; and

● other restraints and burdensome taxes.

These factors may have an adverse effect on our ability to efficiently and cost effectively source our purchased components overseas. In particular, if the U.S. dollar were to depreciate significantly against the currencies in which we purchase raw materials from foreign suppliers, our cost of goods sold could increase materially, which would adversely affect our results of operations.

We are vulnerable to supply disruptions from single-sourced suppliers.

We single-source certain types of parts in our product designs. Any delay in our suppliers’ deliveries may impair our ability to deliver products to our customers. A wide variety of factors could cause such delays including, but not limited to, lack of capacity, economic downturns, availability of credit, weather events or natural disasters.

11

As a U.S. corporation that conducts business in a variety of foreign countries, we are subject to the Foreign Corrupt Practices Act and a variety of anti-corruption laws worldwide. A determination that we violated any of these laws may affect our business and operations adversely.

The U.S. Foreign Corrupt Practices Act (FCPA) generally prohibits U.S. companies and their intermediaries from making improper payments to foreign officials for the purpose of obtaining or keeping business. The United Kingdom Bribery Act (UKBA) prohibits domestic and foreign bribery of the private sector as well as public officials. Any determination that we have violated any anti-corruption laws could have a material adverse effect on our financial position, operating results and cash flows.

Our total assets include goodwill and other indefinite-lived intangibles. If we determine these have become impaired, net income could be materially adversely affected.

Goodwill represents the excess of cost over the fair market value of net assets acquired in business combinations. Indefinite-lived intangibles are comprised of certain tradenames. At December 31, 2017, goodwill and other indefinite-lived intangibles totaled $849.8 million. We review goodwill and other intangibles at least annually for impairment and any excess in carrying value over the estimated fair value is charged to the statement of comprehensive income. Future impairment may result from, among other things, deterioration in the performance of an acquired business or product line, adverse market conditions and changes in the competitive landscape, adverse changes in applicable laws or regulations, including changes that restrict the activities of an acquired business or product line, and a variety of other circumstances. A reduction in net income resulting from the write-down or impairment of goodwill or indefinite-lived intangibles could have a material adverse effect on our financial statements.

We are unable to determine the specific impact of changes in selling prices or changes in volumes or mix of our products on our net sales.

Because of the wide range of products that we sell, the level of customization for many of our products, the frequent rollout of new products, the different accounting systems utilized, and the fact that we do not apply pricing changes uniformly across our entire portfolio of products, we are unable to determine with specificity the effect of volume or mix changes or changes in selling prices on our net sales.

We may not realize all of the anticipated benefits of our acquisitions or those benefits may take longer to realize than expected. We may also encounter significant unexpected difficulties in integrating acquired businesses.

Our ability to realize the anticipated benefits of our acquisitions will depend, to a large extent, on our ability to integrate the acquired businesses with our business. The integration of independent businesses is a complex, costly and time-consuming process. Further, integrating and managing businesses with international operations may pose challenges not previously experienced by our management. As a result, we may be required to devote significant management attention and resources to integrating the business practices and operations of any acquired businesses with ours. The integration process may disrupt our business and, if implemented ineffectively, could preclude realization of the full benefits expected by us. Our failure to meet the challenges involved in integrating an acquired business into our existing operations or otherwise to realize the anticipated benefits of the transaction could cause an interruption of, or a loss of momentum in, our activities and could adversely affect our results of operations.

In addition, the overall integration of our acquired businesses may result in material unanticipated problems, expenses, liabilities, competitive responses, loss of customer relationships, and diversion of management's attention, and may cause our stock price to decline. The difficulties of combining the operations of acquired businesses with ours include, among others:

● managing a larger company;

● maintaining employee morale and retaining key management and other employees;

● complying with newly applicable foreign regulations;

● integrating two business cultures, which may prove to be incompatible;

● the possibility of faulty assumptions underlying expectations regarding the integration process;

● retaining existing customers and attracting new customers;

● consolidating corporate and administrative infrastructures and eliminating duplicative operations;

● the diversion of management's attention from ongoing business concerns and performance shortfalls as a result of the diversion of management's attention to the acquisition;

● unanticipated issues in integrating information technology, communications and other systems;

● unanticipated changes in applicable laws and regulations;

● managing tax costs or inefficiencies associated with integrating the operations of the combined company;

● unforeseen expenses or delays associated with the acquisition;

● difficulty comparing financial reports due to differing financial and/or internal reporting systems; and

● making any necessary modifications to internal financial control standards to comply with the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated thereunder.

12

Many of these factors will be outside of our control and any one of them could result in increased costs, decreases in the amount of expected revenues and diversion of management's time and energy, which could materially impact our business, financial condition and results of operations. In addition, even if the operations of our acquired businesses are integrated successfully with our operations, we may not realize the full benefits of the transaction, including the synergies, cost savings or sales or growth opportunities that we expect. These benefits may not be achieved within the anticipated time frame, or at all. Or, additional unanticipated costs may be incurred in the integration of our businesses. All of these factors could cause dilution to our earnings per share, decrease or delay the expected accretive effect of the acquisition, and cause a decrease in the price of our common stock. As a result, we cannot assure you that the combination of our acquisitions with our business will result in the realization of the full benefits anticipated from the transaction.

We may encounter difficulties in operating or implementing a new enterprise resource planning (ERP) system across our subsidiaries, which may adversely affect our operations and financial reporting.

Over the past two years, we have implemented a new ERP system for a majority of our business as part of our ongoing efforts to improve and strengthen our operational and financial processes and our reporting systems. We expect to implement the new ERP system at our other locations in future years. The ERP system may not provide the benefits anticipated, could add costs and complications to ongoing operations, and may impact our ability to process transactions efficiently, all of which may have a material adverse effect on the Company’s business and results of operations.

Failures or security breaches of our networks or information technology systems could have an adverse effect on our business.

We rely heavily on information technology (IT) both in our products and services for customers and in our IT systems. Further, we collect and store sensitive information in our data centers and on our networks. Government agencies and security experts have warned about growing risks of hackers, cyber-criminals, malicious insiders and other actors targeting confidential information and all types of IT systems. These actors may engage in fraudulent activities, theft of confidential or proprietary information and sabotage.

Our IT systems and our confidential information may be vulnerable to damage or intrusion from a variety of attacks including computer viruses, worms or other malicious software programs. These attacks pose a risk to the security of the products, systems and networks of our customers, suppliers and third-party service providers, as well as to the confidentiality of our information and the integrity and availability of our data. While we attempt to mitigate these risks through controls, due diligence, training, surveillance and other measures, we remain vulnerable to information security threats.

Despite the precautions we take, an intrusion or infection of our systems could result in the disruption of our business, or a loss of proprietary or confidential information. Similarly, an attack on our IT systems could result in theft or disclosure of trade secrets or other intellectual property or a breach of confidential customer or employee information. Any such events could have an adverse impact on sales, harm our reputation and cause us to incur legal liability and increased costs to address such events and related security concerns. As the threats evolve and become more potent, we may incur additional costs to secure the products that we sell, as well as our data and infrastructure of networks and devices.

Recently enacted U.S. tax legislation, as well as future U.S. tax legislation, may adversely affect our business, results of operations, financial condition and cash flow.

On December 22, 2017, the President signed into law Public Law No. 115-97, a comprehensive tax reform bill commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”) that makes significant changes to U.S. federal income tax laws. We have performed a preliminary assessment of the impact of the Tax Act. However, as the Tax Act is complex and far-reaching, there could be future effects of the Tax Act that we have not identified and that could have an adverse effect on our business, results of operations, financial condition and cash flow.

13

Risks related to our common stock

If securities or industry analysts do not publish research or reports about our business, if they adversely change their recommendations regarding our common stock or if our results of operations do not meet their expectations, our common stock price and trading volume could decline.

The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline. Moreover, if one or more of the analysts who cover us downgrade recommendations regarding our stock, or if our results of operations do not meet their expectations, our stock price could decline and such decline could be material.

Anti-takeover provisions in our amended and restated certificate of incorporation and by-laws could prohibit a change of control that our stockholders may favor and could negatively affect our stock price.

Provisions in our amended and restated certificate of incorporation and by-laws may make it more difficult and expensive for a third party to acquire control of us even if a change of control would be beneficial to the interests of our stockholders. These provisions could discourage potential takeover attempts and could adversely affect the market price of our common stock. These provisions may also prevent or frustrate attempts by our stockholders to replace or remove our management. For example, our amended and restated certificate of incorporation and by-laws:

● permit our Board of Directors to issue preferred stock with such terms as they determine, without stockholder approval; 

● provide that only one-third of the members of the Board of Directors are elected at each stockholders meeting and prohibit removal without cause; 

● require advance notice for stockholder proposals and director nominations; and

● contain limitations on convening stockholder meetings.

These provisions make it more difficult for stockholders or potential acquirers to acquire us without negotiation and could discourage potential takeover attempts and could adversely affect the market price of our common stock.

We do not have plans to pay dividends on our common stock in the foreseeable future.

We currently do not have plans to pay dividends in the foreseeable future on our common stock. We intend to use future earnings for the operation and expansion of our business, as well as for repayment of outstanding debt, acquisitions, and for share repurchases. In addition, the terms of our senior secured credit facilities limit our ability to pay dividends on our common stock. As a result, capital appreciation, if any, of our common stock will be the sole source of gain for the foreseeable future. While we may change this policy at some point in the future, we cannot assure that we will make such a change.

Risks related to our capital structure

We have indebtedness which could adversely affect our cash flow and our ability to remain in compliance with debt covenants and make payments on our indebtedness.

As of December 31, 2017, we had total indebtedness of $928.7 million. Our level of indebtedness increases the possibility that we may be unable to generate cash sufficient to pay, when due, the principal of, interest on or other amounts due in respect of our indebtedness. Our indebtedness, combined with our other financial obligations and contractual commitments could have other important consequences. For example, it could:

● make it more difficult for us to satisfy our obligations with respect to our indebtedness, which could result in an event of default under the agreements governing our indebtedness;

● make us more vulnerable to adverse changes in general economic, industry and competitive conditions and adverse changes in government regulation;

● require us to dedicate a portion of our cash flow from operations to interest payments on our indebtedness, thereby reducing the availability of our cash flows to fund working capital, capital expenditures, acquisitions and other general corporate purposes;

● limit our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate; and

● limit our ability to borrow additional amounts for working capital, capital expenditures, acquisitions, debt service requirements, execution of our business strategy or other purposes.

14

Any of the above-listed factors could adversely affect our business, financial condition, results of operations and cash flows. While we maintain interest rate swaps covering a portion of our outstanding debt, our interest expense could increase if interest rates increase because debt under our credit facilities bears interest at a variable rate once above a certain LIBOR floor. If we do not have sufficient earnings to service our debt, we may be required to refinance all or part of our existing debt, sell assets, borrow more money or sell securities, none of which we can guarantee we will be able to do.

The terms of our credit facilities restrict our current and future operations, particularly our ability to respond to changes in our business or to take certain actions.

Our credit facilities contain, and any future indebtedness of ours or our subsidiaries would likely contain, a number of restrictive covenants that impose significant operating and financial restrictions on us and our subsidiaries, including restrictions on our ability to engage in acts that may be in our best long-term interests. These restrictions include, among other things, our ability to:

● incur liens;

● incur or assume additional debt or guarantees or issue preferred stock;

● pay dividends, or make redemptions and repurchases, with respect to capital stock;

● prepay, or make redemptions and repurchases of, subordinated debt;

● make loans and investments;

● make capital expenditures;

● engage in mergers, acquisitions, asset sales, sale/leaseback transactions and transactions with affiliates;

● change the business conducted by us or our subsidiaries; and

● amend the terms of subordinated debt.

The operating and financial restrictions in our credit facilities and any future financing agreements may adversely affect our ability to finance future operations or capital needs or to engage in other business activities. A breach of any of the restrictive covenants in our credit facilities would result in a default. If any such default occurs, the lenders under our credit facilities may elect to declare all outstanding borrowings, together with accrued interest and other fees, to be immediately due and payable, or enforce their security interest, any of which would result in an event of default. The lenders will also have the right in these circumstances to terminate any commitments they have to provide further borrowings. Our existing credit facilities do not contain any financial maintenance covenants.

We may need additional capital to finance our growth strategy or to refinance our existing credit facilities, and we may not be able to obtain it on acceptable terms, or at all, which may limit our ability to grow.

We may require additional financing to expand our business. Financing may not be available to us or may be available to us only on terms that are not favorable. The terms of our senior secured credit facilities limit our ability to incur additional debt. In addition, economic conditions, including a downturn in the credit markets, could impact our ability to finance our growth on acceptable terms or at all. If we are unable to raise additional funds or obtain capital on acceptable terms, we may have to delay, modify or abandon some or all of our growth strategies. In the future, if we are unable to refinance our credit facilities on acceptable terms, our liquidity could be adversely affected.

Item 1B. Unresolved Staff Comments

Holders

As of February 16, 2018, there were approximately 204 registered holders of record of Generac’s common stock. A substantially greater number of holders of Generac common stock are “street name” or beneficial holders, whose shares are held of record by banks, brokers and other financial institutions.

Dividends

We do not have plans to pay dividends on our common stock in the foreseeable future. However, in the future, subject to factors such as general economic and business conditions, our financial condition and results of operations, our capital requirements, our future liquidity and capitalization, and other such factors that our Board of Directors may deem relevant, we may change this policy and choose to pay dividends. Our ability to pay dividends on our common stock is currently restricted by the terms of our senior secured credit facilities and may be further restricted by any future indebtedness we incur. Our business is conducted through our subsidiaries, including our principal operating subsidiary, Generac Power Systems, Inc. Dividends from, and cash generated by our subsidiaries will be our principal sources of cash to repay indebtedness, fund operations, repurchase shares of common stock and pay dividends. Accordingly, our ability to pay dividends to our stockholders is dependent on the earnings and distributions of funds from our subsidiaries, including Generac Power Systems, Inc.

(1)   Our amortization of intangibles expense includes the straight-line amortization of customer lists, patents, certain tradenames and other finite-lived intangible assets.

19

(2)   During the fourth quarter of 2015, our Board of Directors approved a plan to strategically transition and consolidate certain of our brands acquired through acquisitions to the Generac® tradename. This brand strategy change resulted in a reclassification to a two year remaining useful life and a $36.1 million non-cash charge to write-down the impacted tradenames to net realizable value. Additionally, during the fourth quarter of 2015, a $4.6 million goodwill impairment charge was recorded related to the write-down of the Ottomotores reporting unit goodwill. Refer to Note 2, “Significant Accounting Policies – Goodwill and Other Indefinite-Lived Intangible Assets,” to the consolidated financial statements in Item 8 of this Annual Report on Form 10-K for further information on the 2015 impairment charges.

(3)    During the second quarter of 2014, we recorded a gain of $4.9 million related to an adjustment to a certain earn-out obligation in connection with the Tower Light acquisition.

(4)   Represents the non-cash write-off of original issue discount and deferred financing costs due to voluntary debt prepayments. Additionally, for the year ended December 31, 2013, includes the loss on extinguishment of debt as a result of a refinancing transaction in May 2013. Refer to Note 10, “Credit Agreements,” to the consolidated financial statements in Item 8 of this Annual Report on Form 10-K for further information on the losses on extinguishment of debt.

(5)   For the year ended December 31, 2016, represents a non-cash loss in the third quarter 2016 relating to the continued 25 basis point increase in borrowing costs as a result of the credit agreement leverage ratio remaining above 3.0 times based on projections at that time. For the year ended December 31, 2015, represents a non-cash loss relating to a 25 basis point increase in borrowing costs as a result of the credit agreement leverage ratio rising above 3.0 times effective in the third quarter 2015 and expected to remain above 3.0 times based on projections at that time. For the year ended December 31, 2014, represents a non-cash gain relating to a 25 basis point reduction in borrowing costs as a result of the credit agreement leverage ratio falling below 3.0 times effective in the second quarter 2014 and expected to remain below 3.0 times based on projections at that time. Following the May 2017 Term Loan amendment, which removed the pricing grid based on leverage ratio achieved, gains or losses on changes in contractual interest rate will no longer be recorded in the statements of comprehensive income. Refer to Note 10, “Credit Agreements,” to the consolidated financial statements in Item 8 of this Annual Report on Form 10-K for further information on the gains and losses on changes in the contractual interest rate.

(6)   As a result of the Tax Act, we recognized a one-time, non-cash benefit of $28.4 million in the fourth quarter of 2017 primarily from the impact of the revaluation of the net deferred tax liabilities. Refer to Note 13, “Income Taxes,” to the consolidated financial statements in Item 8 of this Annual Report on Form 10-K for further information on the Tax Act and its impact.

(7)   Adjusted EBITDA represents net income before noncontrolling interests, interest expense, taxes, depreciation and amortization, as further adjusted for the other items reflected in the reconciliation table set forth below. The computation of adjusted EBITDA is based on the definition of EBITDA contained in the Term Loan and Amended ABL Facility (terms defined in Note 10, “Credit Agreements,” to the consolidated financial statements in Item 8 of this Annual Report on Form 10-K).

We view Adjusted EBITDA as a key measure of our performance. We present Adjusted EBITDA not only due to its importance for purposes of our credit agreements, but also because it assists us in comparing our performance across reporting periods on a consistent basis as it excludes items that we do not believe are indicative of our core operating performance. Our management uses Adjusted EBITDA:

● for planning purposes, including the preparation of our annual operating budget and developing and refining our internal projections for future periods;

● to allocate resources to enhance the financial performance of our business;

● as a benchmark for the determination of the bonus component of compensation for our senior executives under our management incentive plan, as described further in our Proxy Statement;

● to evaluate the effectiveness of our business strategies and as a supplemental tool in evaluating our performance against our budget for each period; and

● in communications with our Board of Directors and investors concerning our financial performance.

We believe Adjusted EBITDA is used by securities analysts, investors and other interested parties in the evaluation of the Company. Management believes the disclosure of Adjusted EBITDA offers an additional financial metric that, when coupled with results prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) and the reconciliation to U.S. GAAP results, provides a more complete understanding of our results of operations and the factors and trends affecting our business. We believe Adjusted EBITDA is useful to investors for the following reasons:

● Adjusted EBITDA and similar non-GAAP measures are widely used by investors to measure a company's operating performance without regard to items that can vary substantially from company to company depending upon financing and accounting methods, book values of assets, tax jurisdictions, capital structures and the methods by which assets were acquired;

● investors can use Adjusted EBITDA as a supplemental measure to evaluate the overall operating performance of our company, including our ability to service our debt and other cash needs; and

● by comparing our Adjusted EBITDA in different historical periods, our investors can evaluate our operating performance excluding the impact of items described below.

The adjustments included in the reconciliation table listed below are provided for under our Term Loan and Amended ABL Facility, and also are presented to illustrate the operating performance of our business in a manner consistent with the presentation used by our management and Board of Directors. These adjustments eliminate the impact of a number of items that:

● we do not consider indicative of our ongoing operating performance, such as non-cash write-downs and other charges, non-cash gains, write-offs relating to the retirement of debt, severance costs and other restructuring-related business optimization expenses;

● we believe to be akin to, or associated with, interest expense, such as administrative agent fees, revolving credit facility commitment fees and letter of credit fees; or

● are non-cash in nature, such as share-based compensation expense.

We explain in more detail in footnotes (a) through (h) below why we believe these adjustments are useful in calculating Adjusted EBITDA as a measure of our operating performance.

20

Adjusted EBITDA does not represent, and should not be a substitute for, net income or cash flows from operations as determined in accordance with U.S. GAAP. Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation, or as a substitute for analysis of our results as reported under U.S. GAAP. Some of the limitations are:

● Adjusted EBITDA does not reflect our cash expenditures, or future requirements for capital expenditures or contractual commitments;

● Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;

● Adjusted EBITDA does not reflect the significant interest expense, or the cash requirements necessary to service interest or principal payments on our debt;

● although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and Adjusted EBITDA does not reflect any cash requirements for such replacements;

● several of the adjustments that we use in calculating Adjusted EBITDA, such as non-cash write-downs and other charges, while not involving cash expense, do have a negative impact on the value our assets as reflected in our consolidated balance sheet prepared in accordance with U.S. GAAP; and

● other companies may calculate Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure.

Furthermore, as noted above, one of our uses of Adjusted EBITDA is as a benchmark for determining elements of compensation for our senior executives. At the same time, some or all of these senior executives have responsibility for monitoring our financial results, generally including the adjustments in calculating Adjusted EBITDA (subject ultimately to review by our Board of Directors in the context of the Board's review of our financial statements). While many of the adjustments (for example, transaction costs and credit facility fees), involve mathematical application of items reflected in our financial statements, others involve a degree of judgment and discretion. While we believe all of these adjustments are appropriate, and while the calculations are subject to review by our Board of Directors in the context of the Board's review of our financial statements, and certification by our Chief Financial Officer in a compliance certificate provided to the lenders under our Term Loan and Amended ABL Facility, this discretion may be viewed as an additional limitation on the use of Adjusted EBITDA as an analytical tool.

Because of these limitations, Adjusted EBITDA should not be considered as a measure of discretionary cash available to us to invest in the growth of our business. We compensate for these limitations by relying primarily on our U.S. GAAP results and using Adjusted EBITDA only supplementally.

The following table presents a reconciliation of net income to Adjusted EBITDA attributable to Generac Holdings Inc.:

Adjusted EBITDA attributable to Generac Holdings Inc.	$	311,655	$	274,603		$	270,816	$	337,283		$	402,613

(a)   Includes the noncontrolling interests’ share of expenses related to Pramac purchase accounting, including the step-up in value of inventories and intangible amortization of $4.7 million and $8.0 million for the years ended December 31, 2017 and 2016, respectively.

(b)   Represents the following non-cash charges: gains/losses on disposal of assets, unrealized mark-to-market adjustments on commodity contracts, transactional foreign currency gains/losses and certain purchase accounting related adjustments. Additionally, the year ended December 31, 2014 includes a gain of $4.9 million related to an adjustment to an earn-out obligation in connection with the Tower Light acquisition.

We believe that adjusting net income for these non-cash charges is useful for the following reasons:

● The gains/losses on disposals of assets result from the sale of assets that are no longer useful in our business and therefore represent gains or losses that are not from our core operations;

● The adjustments for unrealized mark-to-market gains and losses on commodity contracts represent non-cash items to reflect changes in the fair value of forward contracts that have not been settled or terminated. We believe it is useful to adjust net income for these items because the charges do not represent a cash outlay in the period in which the charge is incurred, although Adjusted EBITDA must always be used together with our U.S. GAAP statements of comprehensive income and cash flows to capture the full effect of these contracts on our operating performance;

● The purchase accounting adjustments represent non-cash items to reflect fair value at the date of acquisition, and therefore do not reflect our ongoing operations; and

● The adjustment to a certain earn-out obligation in connection with the Tower Light acquisition recorded in the year ended December 31, 2014, is a one-time charge that we believe does not reflect our ongoing operations.

21

(c)   Represents share-based compensation expense to account for stock options, restricted stock and other stock awards over their respective vesting period.

(d)  During the fourth quarter of 2015, our Board of Directors approved a plan to strategically transition and consolidate certain of our brands acquired through acquisitions to the Generac® tradename. This brand strategy change resulted in a reclassification to a two year remaining useful life and a $36.1 million non-cash charge to write-down the impacted tradenames to net realizable value. Additionally, during the fourth quarter of 2015, a $4.6 million goodwill impairment charge was recorded related to the write-down of the Ottomotores reporting unit goodwill. Refer to Note 2, “Significant Accounting Policies – Goodwill and Other Indefinite-Lived Intangible Assets,” to the consolidated financial statements in Item 8 of this Annual Report on Form 10-K for further information on the 2015 impairment charges.

(e)   Represents the non-cash write-off of original issue discount and deferred financing costs due to voluntary debt prepayments. Additionally, for the year ended December 31, 2013, includes the loss on extinguishment of debt as a result of a refinancing transaction in May 2013. Refer to Note 10, “Credit Agreements,” to the consolidated financial statements in Item 8 of this Annual Report on Form 10-K for further information on the losses on extinguishment of debt.

(f)   For the year ended December 31, 2016, represents a non-cash loss relating to the continued 25 basis point increase in borrowing costs as a result of the credit agreement leverage ratio remaining above 3.0 times based on projections at that time. For the year ended December 31, 2015, represents a non-cash loss relating to a 25 basis point increase in borrowing costs as a result of the credit agreement leverage ratio rising above 3.0 times and expected to remain above 3.0 times based on projections at that time. For the year ended December 31, 2014, represents a non-cash gain relating to a 25 basis point reduction in borrowing costs as a result of the credit agreement leverage ratio falling below 3.0 times and expected to remain below 3.0 times based on projections at that time. Following the May 2017 Term Loan amendment, which removed the pricing grid based on leverage ratio achieved, gains or losses on changes in contractual interest rate will no longer be recorded in the statements of comprehensive income. Refer to Note 10, “Credit Agreements,” to the consolidated financial statements in Item 8 of this Annual Report on Form 10-K for further information on the gains and losses on changes in the contractual interest rate.

(g)   Represents transaction costs incurred directly in connection with any investment, as defined in our credit agreement, equity issuance, or debt issuance or refinancing, together with certain fees relating to our senior secured credit facilities, such as:

● administrative agent fees and revolving credit facility commitment fees under our Term Loan and Amended ABL Facility, which we believe to be akin to, or associated with, interest expense and whose inclusion in Adjusted EBITDA is therefore similar to the inclusion of interest expense in that calculation;

● transaction costs relating to the acquisition of a business; and

● other financing costs incurred relating to the dividend recapitalization transaction in May 2013.

(h)   Represents severance and non-recurring plant consolidation costs. Additionally, the year ended December 31, 2016 primarily represents charges relating to business optimization and restructuring costs to address the significant and extended downturn for capital spending within the oil & gas industry. These charges represent expenses that are not from our core operations and do not reflect our ongoing operations.

(8)   Adjusted Net Income is defined as net income before noncontrolling interests and provision for income taxes adjusted for the following items: cash income tax expense, amortization of intangible assets, amortization of deferred financing costs and original issue discount related to our debt, intangible impairment charges, certain transaction costs and other purchase accounting adjustments, losses on extinguishment of debt, business optimization expenses, certain other non-cash gains and losses, and adjusted net income attributable to noncontrolling interests.

We believe Adjusted Net Income is used by securities analysts, investors and other interested parties in the evaluation of our company’s operations. Management believes the disclosure of Adjusted Net Income offers an additional financial metric that, when used in conjunction with U.S. GAAP results and the reconciliation to U.S. GAAP results, provides a more complete understanding of our ongoing results of operations, and the factors and trends affecting our business.

The adjustments included in the reconciliation table listed below are presented to illustrate the operating performance of our business in a manner consistent with the presentation used by investors and securities analysts. Similar to the Adjusted EBITDA reconciliation, these adjustments eliminate the impact of a number of items we do not consider indicative of our ongoing operating performance or cash flows, such as amortization costs, transaction costs and write-offs relating to the retirement of debt. We also make adjustments to present cash taxes paid as a result of our favorable tax attributes, causing our cash tax rate to be lower than our U.S GAAP tax rate.

Similar to Adjusted EBITDA, Adjusted Net Income does not represent, and should not be a substitute for, net income or cash flows from operations as determined in accordance with U.S. GAAP. Adjusted Net Income has limitations as an analytical tool, and you should not consider it in isolation, or as a substitute for analysis of our results as reported under U.S. GAAP. Some of the limitations are:

● Adjusted Net Income does not reflect changes in, or cash requirements for, our working capital needs;

● although amortization is a non-cash charge, the assets being amortized may have to be replaced in the future, and Adjusted Net Income does not reflect any cash requirements for such replacements; and

● other companies may calculate Adjusted Net Income differently than we do, limiting its usefulness as a comparative measure.

For the years ended December 31, 2015, 2014 and 2013, amounts are based on actual cash income taxes paid during each year.  

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read together with “Item 1 – Business,” “Item 6 - Selected Financial Data” and the consolidated financial statements and the related notes thereto in Item 8 of this Annual Report on Form 10-K. This discussion contains forward-looking statements, based on current expectations and related to future events and our future financial performance, that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of many factors, including those set forth under “Item 1A - Risk Factors.”

Overview

We are a leading global designer and manufacturer of a wide range of power generation equipment and other engine powered products serving the residential, light commercial and industrial markets. Power generation is our primary focus, which differentiates us from our main competitors that also have broad operations outside of the power equipment market. As the only significant market participant focused predominantly on these products, we have one of the leading market positions in the power equipment market in North America and an expanding presence internationally. We believe we have one of the widest ranges of products in the marketplace, including residential, commercial and industrial standby generators, as well as portable and mobile generators used in a variety of applications. Other engine powered products that we design and manufacture include light towers which provide temporary lighting for various end markets; commercial and industrial mobile heaters and pumps used in the oil & gas, construction and other industrial markets; and a broad product line of outdoor power equipment for residential and commercial use.

Recent Developments

On February 13, 2018, we signed a purchase agreement to acquire Selmec Equipos Industriales, S.A. de C.V. (Selmec), which is headquartered in Mexico City, Mexico. Selmec, which has approximately 300 employees, is a designer and manufacturer of industrial generators ranging from 10 kW to 2,750 kW. Selmec offers a market-leading service platform and specialized engineering capabilities, together with robust integration, project management and remote monitoring services.

Business Drivers and Operational Factors

In operating our business and monitoring its performance, we pay attention to a number of business drivers and trends as well as operational factors. The statements in this section are based on our current expectations.

Business Drivers and Trends

Our performance is affected by the demand for reliable power generation products, mobile product solutions and other engine powered products by our customer base. This demand is influenced by several important drivers and trends affecting our industry, including the following:

Increasing penetration opportunity.    Many potential customers are still not aware of the costs and benefits of automatic backup power solutions. We estimate that penetration rates for home standby generators are only approximately 4.0% of U.S. single-family detached, owner-occupied households with a home value of over $100,000, as defined by the U.S. Census Bureau's 2015 American Housing Survey for the United States. The decision to purchase backup power for many light-commercial buildings such as convenience stores, restaurants and gas stations is more return-on-investment driven and as a result these applications have relatively lower penetration rates as compared to buildings used in code-driven or mission critical applications such as hospitals, wastewater treatment facilities, 911 call centers, data centers and certain industrial locations. The emergence of lower cost, cleaner burning natural gas fueled generators has helped to increase the penetration of standby generators over the past decade in the light-commercial market. In addition, the installed base of backup power for telecommunications infrastructure is still increasing due to the growing importance for uninterrupted voice and data services. We believe by expanding our distribution network, continuing to develop our product line, and targeting our marketing efforts, we can continue to build awareness and increase penetration for our standby generators for residential, commercial and industrial purposes.

Effect of large scale and baseline power disruptions.    Power disruptions are an important driver of customer awareness and have historically influenced demand for generators, both in the United States and internationally. Increased frequency and duration of major power outage events, that have a broader impact beyond a localized level, increases product awareness and may drive consumers to accelerate their purchase of a standby or portable generator during the immediate and subsequent period, which we believe may last for six to twelve months following a major power outage event for standby generators. For example, the major outage events that occurred during the second half of 2017 drove strong demand for portable and home standby generators, and the increased awareness of these products contributed to strong revenue growth in 2017. Major power disruptions are unpredictable by nature and, as a result, our sales levels and profitability may fluctuate from period to period. In addition, there are smaller, more localized power outages that occur frequently across the United States that drive the baseline level of demand for back-up power solutions. The level of baseline power outage activity occurring across the United States can also fluctuate, and may cause our financial results to fluctuate from year to year.

Impact of residential investment cycle.    The market for residential generators is also affected by the residential investment cycle and overall consumer confidence and sentiment. When homeowners are confident of their household income, the value of their home and overall net worth, they are more likely to invest in their home. These trends can have an impact on demand for residential generators. Trends in the new housing market highlighted by residential housing starts can also impact demand for our residential generators. Demand for outdoor power equipment is also impacted by several of these factors, as well as weather precipitation patterns.

Impact of business capital investment cycles.   The global market for our commercial and industrial products is affected by different capital investment cycles, which can vary across the numerous regions around the world in which we participate. These markets include non-residential building construction, durable goods and infrastructure spending as well as investments in the exploration and production of oil & gas, as businesses or organizations either add new locations or make investments to upgrade existing locations or equipment. These trends can have a material impact on demand for these products. The capital investment cycle may differ for the various commercial and industrial end markets that we serve including light commercial, retail, telecommunications, industrial, data centers, healthcare, construction, oil & gas and municipal infrastructure, among others. The market for these products is also affected by general economic and geopolitical conditions as well as credit availability in the geographic regions that we serve. In addition, we believe demand for our mobile power products will continue to benefit from a secular shift towards renting versus buying this type of equipment. We believe the passage of the Tax Act in late 2017 could have a favorable impact on future demand within many of the end markets that we serve, as the improved cash flow, liquidity and business sentiment may lead to further investments in equipment, facilities and infrastructure in the United States.

24

Factors Affecting Results of Operations

We are subject to various factors that can affect our results of operations, which we attempt to mitigate through factors we can control, including continued product development, expanded distribution, pricing, cost control and hedging. Certain operational and other factors that affect our business include the following:

Effect of commodity, currency and component price fluctuations.    Industry-wide price fluctuations of key commodities, such as steel, copper and aluminum, along with other components we use in our products, can have a material impact on our results of operations. Also, acquisitions in recent years have further expanded our commercial and operational presence outside of the United States. These acquisitions, along with our existing international presence, exposes us to fluctuations in foreign currency exchange rates that can have a material impact on our results of operations.

We have historically attempted to mitigate the impact of rising commodity, currency and component prices through improved product design and sourcing, manufacturing efficiencies, price increases and select hedging transactions. Our results are also influenced by changes in fuel prices in the form of freight rates, which in some cases are accepted by our customers and in other cases are paid by us.

Seasonality.    Although there is demand for our products throughout the year, in each of the past five years approximately 20% to 27% of our net sales occurred in the first quarter, 22% to 25% in the second quarter, 24% to 27% in the third quarter and 25% to 29% in the fourth quarter, with different seasonality depending on the occurrence, timing and severity of major power outage activity in each year. Major outage activity is unpredictable by nature and, as a result, our sales levels and profitability may fluctuate from period to period. The seasonality experienced during a major power outage, and for the subsequent quarters following the event, will vary relative to other periods where no major outage events occurred. We maintain a flexible production and supply chain infrastructure in order to respond to outage-driven peak demand.

Factors influencing interest expense and cash interest expense.   Interest expense can be impacted by a variety of factors, including market fluctuations in LIBOR, interest rate election periods, interest rate swap agreements, and repayments or borrowings of indebtedness. Cash interest expense decreased during 2017 compared to 2016, primarily due to the $25 million voluntary prepayment of Term Loan debt in November 2016, the May and December 2017 Term Loan refinancings, the repayment of $100 million of ABL Facility borrowings, and decreased borrowings at other subsidiaries; partially offset by an increase in the LIBOR rate. Refer to Note 10, “Credit Agreements,” to the consolidated financial statements in Item 8 of this Annual Report on Form 10-K for further information.

Factors influencing provision for income taxes and cash income taxes paid.   On December 22, 2017, the U.S. government enacted the Tax Act, which significantly changes how the U.S. taxes corporations. The Tax Act requires complex computations to be performed that were not previously required in U.S. tax law, significant judgments to be made in interpretation of the provisions of the Tax Act and significant estimates in calculations, and the preparation and analysis of information not previously relevant or regularly produced. The U.S. Treasury Department, the IRS, and other standard-setting bodies could interpret or issue guidance on how provisions of the Tax Act will be applied or otherwise administered that is different from our interpretation.

As a result of the Tax Act, we recognized a one-time, non-cash benefit of $28.4 million in the fourth quarter of 2017 primarily from the impact of the revaluation of our net deferred tax liabilities. While the Company continues to assess the full impact of the Tax Act, the preliminary analysis suggests a meaningful benefit from the legislation. Specifically for 2018, the combined federal and state effective tax rate is expected to decline to between 25 to 26%, resulting in lower cash income taxes. As we complete our analysis of the Tax Act, collect and prepare necessary data, and interpret any additional guidance, we may make adjustments to provisional amounts that we have recorded that may materially impact our provision for income taxes in the period in which the adjustments are made. Refer to Note 13, “Income Taxes,” to the consolidated financial statements in Item 8 of this Annual Report on Form 10-K for further information on the Tax Act and its impact.

Further, we had approximately $470 million of tax-deductible goodwill and intangible asset amortization remaining as of December 31, 2017 related to our acquisition by CCMP Capital Advisors, LLC in 2006 that we expect to generate aggregate cash tax savings of approximately $122 million through 2021, assuming continued profitability and a 26% combined federal and state tax rate. The aggregate cash tax savings reflects a decrease of $61 million due to a reduction in the assumed tax rate from 39% to 26% as a result of the Tax Act. The recognition of the tax benefit associated with these assets for tax purposes is expected to be $122 million annually through 2020 and $102 million in 2021, which generates annual cash tax savings of $32 million through 2020 and $26 million in 2021, assuming profitability and a 26% combined federal and state tax rate. As a result of the asset acquisition of the Magnum business in the fourth quarter of 2011, we had approximately $34 million of incremental tax deductible goodwill and intangible assets remaining as of December 31, 2017. We expect these assets to generate aggregate cash tax savings of $9.0 million through 2026 assuming continued profitability and a 26% combined federal and state tax rate. The aggregate cash tax savings reflects a decrease of $4.5 million due to a reduction in the assumed tax rate from 39% to 26% as a result of the Tax Act. The amortization of these assets for tax purposes is expected to be $3.8 million annually through 2025 and $2.8 million in 2026, which generates an additional annual cash tax savings of $1.0 million through 2025 and $0.7 million in 2026, assuming profitability and a 26% combined federal and state tax rate. Based on current business plans, we believe that our cash tax obligations through 2026 will be significantly reduced by these tax attributes. Other domestic acquisitions have resulted in additional tax deductible goodwill and intangible assets that will generate tax savings, but are not material to the Company’s consolidated financial statements.

Acquisitions.   Over the years, we have executed a number of acquisitions that supported our strategic plan. A summary of the recent acquisitions can be found in Note 1, “Description of Business,” to the consolidated financial statements in Item 8 of this Annual Report on Form 10-K.

Components of Net Sales and Expenses

Net Sales

Substantially all of our net sales are generated through the sale of our power generation equipment and other engine powered products to the residential, light commercial and industrial markets. We also sell service parts to our dealer network. Net sales, which include shipping and handling charges billed to customers, are generally recognized upon shipment of products to our customers. Related freight costs are included in cost of sales.

We are not dependent on any one channel or customer for our net sales, with no single customer representing more than 6% of our sales, and our top ten customers representing less than 22% of our total sales for the year ended December 31, 2017.

Costs of Goods Sold

The principal elements of costs of goods sold in our manufacturing operations are component parts, raw materials, factory overhead and labor. Component parts and raw materials comprised approximately 77% of costs of goods sold for the year ended December 31, 2017. The principal component parts are engines and alternators. We design and manufacture air-cooled engines for certain of our generators up to 22kW, along with certain liquid-cooled engines. We source engines for certain of our smaller products and all of our diesel products. For certain natural gas engines, we source the base engine block, and then add a significant amount of value engineering, sub-systems and other content to the point that we are recognized as the OEM of those engines. We design many of the alternators for our units and either manufacture or source alternators for certain of our units. We also manufacture other generator components where we believe we have a design and cost advantage. We source component parts from an extensive global network of reliable, high quality suppliers. In some cases, these relationships are proprietary.

The principal raw materials used in the manufacturing process that are sourced are steel, copper and aluminum. We are susceptible to fluctuations in the cost of these commodities, impacting our costs of goods sold. We seek to mitigate the impact of commodity prices on our business through a continued focus on global sourcing, product design improvements, manufacturing efficiencies, price increases and select hedging transactions. There is typically a lag between raw material price fluctuations and their effect on our costs of goods sold.

Other sources of costs include our manufacturing and warehousing facilities, factory overhead, labor and shipping costs. Factory overhead includes utilities, support personnel, depreciation, general supplies, support and maintenance. Although we attempt to maintain a flexible manufacturing cost structure, our margins can be impacted when we cannot timely adjust labor and manufacturing costs to match fluctuations in net sales.

Operating Expenses

Our operating expenses consist of costs incurred to support our sales, marketing, distribution, service parts, engineering, information systems, human resources, finance, risk management, legal and tax functions, among others. These expenses include personnel costs such as salaries, bonuses, employee benefit costs and taxes, and are classified into three categories: selling and service, research and development, and general and administrative. Additionally, the amortization expense related to our finite-lived intangible assets is included within operating expenses.

Selling and service.    Our selling and service expenses consist primarily of personnel expense, marketing expense, warranty expense and other sales expenses. Our personnel expense recorded in selling and services expenses includes the expense of our sales force responsible for our broad customer base and other personnel involved in the marketing, sales and service of our products. Warranty expense, which is recorded at the time of sale, is estimated based on historical trends. Our marketing expenses include direct mail costs, printed material costs, product display costs, market research expenses, trade show expenses, media advertising, promotional expenses and co-op advertising costs. Marketing expenses are generally related to the launch of new product offerings, participation in trade shows and other events, and opportunities to create market awareness for home standby generators in areas impacted by heightened power outage activity.

Research and development.    Our research and development expenses support numerous projects covering all of our product lines. We operate engineering facilities at many locations globally and employ over 350 personnel with focus on new product development, existing product improvement and cost containment. We are committed to research and development, and rely on a combination of patents and trademarks to establish and protect our proprietary rights. Our research and development costs are expensed as incurred.

General and administrative.    Our general and administrative expenses include personnel costs for general and administrative employees; accounting, legal and professional services fees; information technology costs; insurance; travel and entertainment expense; and other corporate expenses.

26

Amortization of intangibles.    Our amortization of intangibles expense includes the straight-line amortization of finite-lived tradenames, customer lists, patents and other intangibles assets.

Other (Expense) Income

Other (expense) income includes the interest expense on our outstanding borrowings, amortization of debt financing costs and original issue discount, and expenses related to interest rate swap agreements. Other (expense) income also includes other financial items such as losses on extinguishment of debt, gains (losses) on change in contractual interest rate, interest income earned on our cash and cash equivalents, and costs related to acquisitions.

Total net sales	$	1,672,445	$	1,444,453		227,992		15.8	%

Net sales.    The increase in Domestic sales for the year ended December 31, 2017 was primarily due to strong growth in shipments of home standby and portable generators driven by increased power outage activity, along with strong growth for mobile products due to recovery in the general rental and oil & gas markets, given the continued replacement cycle by our rental customers.

The increase in International sales for the year ended December 31, 2017 was due to the contribution from the recent acquisitions of Pramac and Motortech. The growth was also due to increased organic shipments of both C&I and residential products within the European and Latin America regions.

The total contribution from non-annualized recent acquisitions for the year ended December 31, 2017 was $69.7 million.

Gross profit.    Gross profit margin for the year ended December 31, 2017 was 34.8% compared to 35.6% for the year ended December 31, 2016. The prior year included $2.7 million of business optimization and restructuring costs classified within cost of goods sold to address the significant and extended downturn for capital spending within the oil & gas industry, as well as $4.2 million of expense relating to the purchase accounting adjustment for the step-up in value of inventories relating to the Pramac acquisition. The current year included $2.0 million of business optimization and non-recurring plant consolidation costs. Excluding the impact of these charges, pro-forma gross margins were 34.9% and 36.1% in 2017 and 2016, respectively. The pro-forma decrease in gross margins was primarily due to unfavorable sales mix attributable to higher organic sales within the International segment and of mobile products relative to prior year, which carry lower gross margins relative to the consolidated average. Additionally, the mix impact from the Pramac and Motortech acquisitions, and higher commodity prices negatively impacted gross margin. These impacts were partially offset by improved leverage of fixed manufacturing costs on the higher organic sales volumes and net favorable pricing impacts.

Operating expenses.    Operating expenses increased $21.6 million, or 7.0%, as compared to the year ended December 31, 2016. The prior year included $4.4 million of business optimization and restructuring costs classified within operating expenses to address the downturn for capital spending within the oil & gas industry. Excluding the impact of these charges, operating expenses increased $26.0 million, or 8.5%, as compared to the prior year. The increase was primarily due to the addition of recurring operating expenses associated with the Pramac and Motortech acquisitions, and an increase in personnel costs including higher incentive compensation accrued during the current year; partially offset by a decline in amortization of intangibles.

Other expense.   The decrease in other expense was primarily due to a prior year $3.0 million non-cash loss on change in contractual interest rate not repeating and a prior year $0.6 million loss on extinguishment of debt resulting from a $25.0 million voluntary prepayment of Term Loan debt. Additionally, interest expense decreased in the current year due to that $25.0 million Term Loan prepayment in November 2016, Term Loan repricings in May and December 2017, and decreased borrowings at other subsidiaries. These impacts were partially offset by an increase in LIBOR rates and foreign currency transactional losses.

Provision for income taxes.    The effective income tax rates for the years ended December 31, 2017 and 2016 were 21.3% and 36.8%, respectively. The decrease in the effective income tax rate is primarily due to the provisional favorable effect of the Tax Act, including a one-time, non-cash benefit of $28.4 million recorded in the fourth quarter of 2017, as well as excess tax benefits from share-based compensation. Refer to Note 13, “Income Taxes,” to the consolidated financial statements in Item 8 of this Annual Report on Form 10-K for further information on the Tax Act and its impact.

Net income attributable to Generac Holdings Inc.    The increase in net income attributable to Generac Holdings Inc. was primarily due to the factors outlined above partially offset by an increase in net income attributable to noncontrolling interests.

Adjusted EBITDA. Adjusted EBITDA margins for the Domestic segment for the year ended December 31, 2017 were 22.4% of net sales as compared to 22.3% of net sales for the year ended December 31, 2016. This increase was primarily due to improved overall leverage of fixed operating expenses on the organic increase in sales, and the net favorable impact of pricing. These impacts were partially offset by higher commodity prices and an increase in personnel costs including higher incentive compensation accrued during the current year.

28

Adjusted EBITDA margins for the International segment for the year ended December 31, 2017 were 7.2% of net sales as compared to 6.3% of net sales for the year ended December 31, 2016. The increase was primarily due improved overall leverage of fixed manufacturing and operating expenses on the organic increase in sales, the addition of the Motortech acquisition and cost reduction actions. These impacts were partially offset by higher commodity prices and increased operating expenses associated with the expansion of certain branch operations.

Adjusted net income.    Adjusted Net Income of $212.9 million for the year ended December 31, 2017 increased 7.4% from $198.3 million for the year ended December 31, 2016, due to the factors outlined above, partially offset by an increase in cash income tax expense.

Net sales.   The decrease in Domestic sales for the year ended December 31, 2016 was primarily due to significant declines in shipments of mobile products into oil & gas and general rental markets. Partially offsetting this was the contribution from the CHP acquisition, along with increased shipments of portable and home standby generators.

29

The increase in International sales for the year ended December 31, 2016 was due to the contribution from the Pramac acquisition. Partially offsetting this impact were declines in organic shipments of mobile products into the European region.

The total contribution from non-annualized recent acquisitions for the year ended December 31, 2016 was $236.6 million.

Net income attributable to Generac Holdings Inc.    Net income attributable to Generac Holdings Inc. for the year ended December 31, 2016 includes the impact of $7.1 million of non-recurring, pre-tax charges relating to business optimization and restructuring costs to address the impact of the significant and extended downturn for capital spending within the oil & gas industry. The cost-reduction actions taken include the consolidation of production facilities, headcount reductions, certain non-cash asset write-downs and other non-recurring product-related charges. The charges consist of $2.7 million classified within cost of goods sold and $4.4 million classified within operating expenses. The increase in net income attributable to Generac Holdings Inc. was primarily due to a 2015 $40.7 million pre-tax, non-cash charge for the impairment of certain intangible assets, partially offset by the business optimization charge discussed above and the other factors outlined in this section.

Gross profit.    Gross profit margin for the year ended December 31, 2016 was 35.6% compared to 34.9% for the year ended December 31, 2015, which includes the impact of the aforementioned $2.7 million of business optimization charges classified within cost of goods sold, as well as $4.2 million of expense relating to the purchase accounting adjustment for the step-up in value of inventories relating to the Pramac acquisition. Excluding the impact of these adjustments, pro-forma gross profit margin was 36.1%, an improvement of 120 basis points over the year ended December 31, 2015. The pro-forma increase was primarily due to the favorable impacts from lower commodity costs and overseas sourcing benefits from a stronger U.S. Dollar, along with an overall favorable organic product mix. In addition, gross margin in 2015 was negatively impacted by temporary increases in certain costs associated with the west coast port congestion as well as other overhead-related costs that did not repeat in the current year. These factors were partially offset by the mix impact from the Pramac acquisition.

Operating expenses.    Excluding the impact of the aforementioned $4.4 million of business optimization charges and 2015 $40.7 million of intangible impairment charges classified within operating expenses, operating expenses increased $65.4 million, or 27.3%, to $305.1 million for the year ended December 31, 2016 from $239.7 million for the year ended December 31, 2015. The increase was primarily due to the addition of recurring operating expenses associated with recent acquisitions and increased amortization expense.

Other expense.   Other expense in 2015 included a non-cash $4.8 million loss on extinguishment of debt resulting from $150.0 million of voluntary prepayments of Term Loan debt, and a $2.4 million non-cash loss resulting from an increase in our Term Loan interest rate spread of 25 basis points. In 2016, other expense included a $3.0 million non-cash loss resulting from a continuation of the 25 basis point spread increase, and a $0.6 million loss on extinguishment of debt resulting from a $25.0 million voluntary prepayment of Term Loan debt.

Provision for ncome taxes.    The effective income tax rates for the years ended December 31, 2016 and 2015 were both 36.8%.

Adjusted EBITDA. Adjusted EBITDA margins for the Domestic segment for the year ended December 31, 2016 were 22.3% of net sales as compared to 21.2% of net sales for the year ended December 31, 2015. This increase was primarily due to overall favorable product mix; lower commodity costs and overseas sourcing benefits from a stronger U.S. Dollar; and the benefit of cost-reduction actions within domestic mobile products, partially offset by increased promotional activities.

Adjusted EBITDA margins for the International segment for the year ended December 31, 2016 were 6.3% of net sales as compared to 14.1% of net sales for the year ended December 31, 2015. This decrease was primarily due to a large decline in mobile products margins given the reduced operating leverage on lower organic sales volume, unfavorable sales mix, foreign currency impacts with the weakness in the British Pound, and, to a lesser extent, the Pramac acquisition sales mix.

Adjusted net income.    Adjusted Net Income of $198.3 million for the year ended December 31, 2016 decreased 0.1% from $198.4 million for the year ended December 31, 2015. The increased earnings outlined above were offset by an increase in cash income tax expense and adjusted net income attributable to noncontrolling interests.

Liquidity and Financial Position

Our primary cash requirements include payment for our raw material and component supplies, salaries & benefits, facility and lease costs, operating expenses, interest and principal payments on our debt and capital expenditures. We finance our operations primarily through cash flow generated from operations and, if necessary, borrowings under our Amended ABL Facility.

30

Our credit agreements originally provided for a $1.2 billion term loan B credit facility (Term Loan) and include a $300.0 million uncommitted incremental term loan facility. The Term Loan matures on May 31, 2023. The Term Loan currently bears interest at rates based upon either a base rate plus an applicable margin of 1.00% or adjusted LIBOR rate plus an applicable margin of 2.00%, subject to a LIBOR floor of 0.75%. As of December 31, 2017, the Company is in compliance with all covenants of the Term Loan. There are no financial maintenance covenants on the Term Loan.

Our credit agreements also provide for the $250.0 million Amended ABL Facility. The maturity date of the Amended ABL Facility is May 29, 2020. As of December 31, 2017, there was $249.7 million of availability under the Amended ABL Facility, net of outstanding letters of credit. The Company is in compliance with all covenants of the Amended ABL Facility.

In August 2015, our Board of Directors approved a $200.0 million stock repurchase program, which we completed in the third quarter of 2016. In October 2016, our Board of Directors approved another stock repurchase program, under which we may repurchase an additional $250.0 million of common stock over 24 months from time to time; in amounts and at prices we deem appropriate, subject to market conditions and other considerations. During the year ended December 31, 2017, we repurchased 844,500 shares of our common stock for $30.0 million; during the year ended December 31, 2016, we repurchased 3,968,706 shares of our common stock for $149.9 million; and during the year ended December 31, 2015, we repurchased 3,303,500 shares of our common stock for $99.9 million, all funded with cash on hand.

Refer to Note 10, “Credit Agreements,” to the consolidated financial statements in Item 8 of this Annual Report on Form 10-K for additional information.

Long-term Liquidity

We believe that our cash flow from operations and availability under our Amended ABL Facility, combined with relatively low ongoing capital expenditure requirements and favorable tax attributes (which result in a lower cash tax rate as compared to the U.S. statutory tax rate) provide us with sufficient capital to continue to grow our business in the future. We will use a portion of our cash flow to pay interest and principal on our outstanding debt as well as repurchase shares of our common stock, impacting the amount available for working capital, capital expenditures and other general corporate purposes. As we continue to expand our business, we may require additional capital to fund working capital, capital expenditures or acquisitions.

Cash Flow

Year ended December 31, 2017 compared to year ended December 31, 2016

The following table summarizes our cash flows by category for the periods presented:

	Year Ended December 31,
(U.S. Dollars in thousands)	2017			2016			Change		% Change
Net cash provided by operating activities	$	261,116		$	253,409		$	7,707		3.0	%
Net cash used in investing activities		(31,922	)		(105,822	)		73,900		-69.8	%
Net cash used in financing activities		(160,143	)		(195,705	)		35,562		-18.2	%

The 3.0% increase in net cash provided by operating activities was primarily driven by an overall increase in operating earnings, partially offset by a lesser benefit from working capital reductions during the current year, which was primarily due to replenishing inventory levels in the first quarter of 2017 following Hurricane Matthew, and ramping up production in the second half of 2017 in response to Hurricanes Harvey, Irma and Maria.

Net cash used in investing activities for the year ended December 31, 2017 primarily consisted of cash payments for the purchase of property and equipment. Net cash used in investing activities for the year ended December 31, 2016 primarily represents cash payments of $76.7 million related to the acquisition of businesses and $30.5 million for the purchase of property and equipment.

Net cash used in financing activities for the year ended December 31, 2017 primarily consisted of $232.4 million of debt repayments ($117.5 million of long-term borrowings and $114.9 million of short-term borrowings), $30.0 million for the repurchase of the Company’s common stock, $5.9 million of taxes paid related to equity awards and $3.9 million of payments for debt issuance costs. These payments were partially offset by $105.1 million cash proceeds from borrowings ($102.0 million for short-term borrowings and $3.1 million for long-term borrowings) and $7.0 million of proceeds from the exercise of stock options.

Net cash used in financing activities for the year ended December 31, 2016 primarily consisted of $149.9 million for the repurchase of the Company’s common stock, $65.4 million of debt repayments ($37.6 million of long-term borrowings and $27.8 million of short-term borrowings) and $12.4 million of taxes paid related to equity awards. These payments were partially offset by $28.7 million cash proceeds from short-term borrowings and $7.9 million of excess tax benefits from equity awards.

31

Year ended December 31, 2016 compared to year ended December 31, 2015

The following table summarizes our cash flows by category for the periods presented:

	Year Ended December 31,
(U.S. Dollars in thousands)	2016			2015			Change			% Change
Net cash provided by operating activities	$	253,409		$	188,619		$	64,790			34.3	%
Net cash used in investing activities		(105,822	)		(104,328	)		(1,494	)		1.4	%
Net cash used in financing activities		(195,705	)		(154,483	)		(41,222	)		26.7	%

The 34.3% increase in net cash provided by operating activities was primarily driven by a reduction in working capital investment during 2016 as compared to the larger investment that was incurred in 2015, and an overall increase in operating earnings.

Net cash used in investing activities for the year ended December 31, 2016 primarily consisted of cash payments of $76.7 million related to the acquisitions of businesses and $30.5 million for the purchase of property and equipment. Net cash used in investing activities for the year ended December 31, 2015 primarily represents cash payments of $74.6 million related to the acquisition of CHP and $30.7 million for the purchase of property and equipment.

Net cash used in financing activities for the year ended December 31, 2016 primarily consisted of $149.9 million for the repurchase of the Company’s common stock, $65.4 million of debt repayments ($37.6 million of long-term borrowings and $27.8 million of short-term borrowings) and $12.4 million of taxes paid related to equity awards. These payments were partially offset by $28.7 million cash proceeds from short-term borrowings and $7.9 million of excess tax benefits from equity awards.

Net cash used in financing activities for the year ended December 31, 2015 primarily consisted of $174.0 million of debt repayments ($150.8 million of long-term borrowings and $23.2 million of short-term borrowings), partially offset by $126.4 million cash proceeds from borrowings ($100.0 million from long-term borrowings under the Amended ABL facility and $26.4 million from short-term borrowings). In addition, the Company paid $99.9 million for the repurchase of its common stock and $13.0 million of taxes related to equity awards, which was partially offset by $9.6 million of excess tax benefits from equity awards.

Senior Secured Credit Facilities

Refer to Note 10, “Credit Agreements,” to the consolidated financial statements in Item 8 and the “Liquidity and Financial Position” section included in Item 7 of this Annual Report on Form 10-K for information on the senior secured credit facilities.

Covenant Compliance

The Term Loan contains restrictions on the Company’s ability to pay distributions and dividends. Payments can be made to the Company or other parent companies for certain expenses such as operating expenses in the ordinary course, fees and expenses related to any debt or equity offering and to pay franchise or similar taxes. Dividends can be used to repurchase equity interests, subject to limitations in certain circumstances. Additionally, the Term Loan restricts the aggregate amount of dividends and distributions that can be paid and, in certain circumstances, requires pro forma compliance with certain fixed charge coverage ratios or gross leverage ratios, as applicable, in order to pay certain dividends and distributions. The Term Loan also contains other affirmative and negative covenants that, among other things, limit the incurrence of additional indebtedness, liens on property, sale and leaseback transactions, investments, loans and advances, mergers or consolidations, asset sales, acquisitions, transactions with affiliates, prepayments of certain other indebtedness and modifications of our organizational documents. The Term Loan does not contain any financial maintenance covenants.

The Term Loan contains customary events of default, including, among others, nonpayment of principal, interest or other amounts, failure to perform covenants, inaccuracy of representations or warranties in any material respect, cross-defaults with other material indebtedness, certain undischarged judgments, the occurrence of certain ERISA, bankruptcy or insolvency events, or the occurrence of a change in control (as defined in the Term Loan). A bankruptcy or insolvency event of default will cause the obligations under the Term Loan to automatically become immediately due and payable.

The Amended ABL Facility also contains covenants and events of default substantially similar to those in the Term Loan, as described above. 

32

Contractual Obligations

The following table summarizes our expected payments for significant contractual obligations as of December 31, 2017, using the interest rates in effect as of that date:

(U.S. Dollars in thousands)	Total		Less than 1 Year		2 - 3 Years		4 - 5 Years		After 5 Years
Long-term debt, including curent portion (1)	$	930,367	$	936	$	431	$	-	$	929,000
Capital lease obligations, including current portion		4,690		636		1,246		1,755		1,053
Interest on long-term debt		186,357		34,455		68,925		68,750		14,227
Operating leases		43,924		9,497		15,282		13,280		5,865
Total contractual cash obligations (2)	$	1,165,338	$	45,524	$	85,884	$	83,785	$	950,145

(1) The Term Loan originally provided for a $1.2 billion term loan B credit facility and includes a $300.0 million uncommitted incremental term loan facility. The Term Loan matures on May 31, 2023. The Amended ABL Facility provides for a $250.0 million senior secured ABL revolving credit facility, which matures on May 29, 2020. There was no outstanding balance on the Amended ABL Facility as of December 31, 2017.

(2) Pension obligations are excluded from this table as we are unable to estimate the timing of payment due to the inherent assumptions underlying the obligation. However, at a minimum, the Company estimates we will contribute $0.3 million to our pension plans in 2018.

Capital Expenditures

Our operations require capital expenditures for technology, tooling, equipment, capacity expansion, systems and upgrades. Capital expenditures were $33.3 million, $30.5 million and $30.7 million for the years ended December 31, 2017, 2016 and 2015, respectively, and were funded through cash from operations.

Off-Balance Sheet Arrangements

We have an arrangement with a finance company to provide floor plan financing for selected dealers. This arrangement provides liquidity for our dealers by financing dealer purchases of products with credit availability from the finance company. We receive payment from the finance company after shipment of product to the dealer and our dealers are given a longer period of time to pay the finance provider. If our dealers do not pay the finance company, we may be required to repurchase the applicable inventory held by the dealer. We do not indemnify the finance company for any credit losses they may incur.

Total inventory financed under this arrangement accounted for approximately 9% and 8% of net sales for the years ended December 31, 2017 and 2016, respectively. The amount financed by dealers which remained outstanding was $36.5 million and $33.9 million as of December 31, 2017 and 2016, respectively.

Critical Accounting Policies

In preparing the financial statements in accordance with U.S. GAAP, management is required to make estimates and assumptions that have an impact on the asset, liability, revenue and expense amounts reported. These estimates can also affect supplemental information disclosures of the Company, including information about contingencies, risk and financial condition. The Company believes, given current facts and circumstances, that its estimates and assumptions are reasonable, adhere to U.S. GAAP, and are consistently applied. Inherent in the nature of an estimate or assumption is the fact that actual results may differ from estimates and estimates may vary as new facts and circumstances arise. The Company makes routine estimates and judgments in determining net realizable value of accounts receivable, inventories, property and equipment, prepaid expenses, product warranties and other reserves. Management believes the Company’s most critical accounting estimates and assumptions are in the following areas: goodwill and other indefinite-lived intangible asset impairment assessment; business combinations and purchase accounting; defined benefit pension obligations and income taxes.

Goodwill and Other Indefinite-Lived Intangible Assets

Refer to Note 2, “Significant Accounting Policies – Goodwill and Other Indefinite-Lived Intangible Assets,” to the consolidated financial statements in Item 8 of this Annual Report on Form 10-K for further information on the Company’s policy regarding the accounting for goodwill and other intangible assets.

The Company performed the required annual impairment tests for goodwill and other indefinite-lived intangible assets for the fiscal years 2017, 2016 and 2015, and found no impairment following the 2017 and 2016 tests. There were no reporting units with a carrying value at-risk of exceeding fair value as of the October 31, 2017 impairment test date.

33

After performing the impairment tests for fiscal year 2015, the Company determined that the fair value of the Ottomotores reporting unit was less than its carrying value, resulting in a non-cash goodwill impairment charge of $4.6 million in the fourth quarter of 2015. The fair value was determined using a discounted cash flow analysis, which utilizes key estimates and assumptions as discussed below. Additionally, in the fourth quarter of 2015, the Company’s Board of Directors approved a plan to strategically transition and consolidate certain of the Company’s brands acquired through acquisitions to the Generac® tradename. This brand strategy change resulted in a reclassification to a two year remaining useful life for the impacted tradenames, causing the fair value to be less than the carrying value using the relief-from-royalty approach in a discounted cash flow analysis. As such, a $36.1 million non-cash impairment charge was recorded in the fourth quarter of 2015 to write-down the impacted tradenames to net realizable value. See Note 2, “Significant Accounting Policies – Goodwill and Other Indefinite-Lived Intangible Assets,” to the consolidated financial statements in Item 8 of this Annual Report on Form 10-K for further information on the impairment charges recorded in 2015.

When preparing a discounted cash flow analysis for purposes of our annual impairment test, we make a number of key estimates and assumptions. We estimate the future cash flows of the business based on historical and forecasted revenues and operating costs. This, in turn, involves further estimates, such as estimates of future growth rates and inflation rates. In addition, we apply a discount rate to the estimated future cash flows for the purpose of the valuation. This discount rate is based on the estimated weighted average cost of capital for the business and may change from year to year. Weighted average cost of capital includes certain assumptions such as market capital structures, market betas, risk-free rate of return and estimated costs of borrowing.

As noted above, a considerable amount of management judgment and assumptions are required in performing the goodwill and indefinite-lived intangible asset impairment tests. While we believe our judgments and assumptions are reasonable, different assumptions could change the estimated fair values. A number of factors, many of which we have no ability to control, could cause actual results to differ from the estimates and assumptions we employed. These factors include:

● a prolonged global or regional economic downturn;

● a significant decrease in the demand for our products;

● the inability to develop new and enhanced products and services in a timely manner;

● a significant adverse change in legal factors or in the business climate;

● an adverse action or assessment by a regulator;

● successful efforts by our competitors to gain market share in our markets;

● disruptions to the Company’s business;

● inability to effectively integrate acquired businesses;

● unexpected or planned changes in the use of assets or entity structure; and

● business divestitures.

If management's estimates of future operating results change or if there are changes to other assumptions due to these factors, the estimate of the fair values may change significantly. Such change could result in impairment charges in future periods, which could have a significant impact on our operating results and financial condition.

Business Combinations and Purchase Accounting

We account for business combinations using the acquisition method of accounting, and accordingly, the assets and liabilities of the acquired business are recorded at their respective fair values. The excess of the purchase price over the estimated fair value of assets and liabilities is recorded as goodwill. Assigning fair market values to the assets acquired and liabilities assumed at the date of an acquisition requires knowledge of current market values, the values of assets in use, and often requires the application of judgment regarding estimates and assumptions. While the ultimate responsibility resides with management, for material acquisitions we retain the services of certified valuation specialists to assist with assigning estimated values to certain acquired assets and assumed liabilities, including intangible assets and tangible long-lived assets. Acquired intangible assets, excluding goodwill, are valued using certain discounted cash flow methodologies based on future cash flows specific to the type of intangible asset purchased. This methodology incorporates various estimates and assumptions, the most significant being projected revenue growth rates, earnings margins, and forecasted cash flows based on the discount rate and terminal growth rate. Refer to Note 1, “Description of Business,” to the consolidated financial statements in Item 8 of this Annual Report on Form 10-K for further information on the Company’s business acquisitions.

Defined Benefit Pension Obligations

The Company’s pension benefit obligation and related pension expense or income are calculated in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 715-30, Defined Benefit Plans—Pension, and are impacted by certain actuarial assumptions, including the discount rate and the expected rate of return on plan assets. Such rates are evaluated on an annual basis considering factors including market interest rates and historical asset performance. Actuarial valuations for fiscal year 2017 used a discount rate of 3.60% for the salaried pension plan and 3.62% for the hourly pension plan. Our discount rate was selected using a methodology that matches plan cash flows with a selection of “Aa” or higher rated bonds, resulting in a discount rate that better matches a bond yield curve with comparable cash flows. In estimating the expected return on plan assets, we study historical markets and preserve the long-term historical relationships between equities and fixed-income securities. We evaluate current market factors such as inflation and interest rates before we determine long-term capital market assumptions and review peer data and historical returns to check for reasonableness and appropriateness. Changes in the discount rate and return on assets can have a significant effect on the funded status of our pension plans, stockholders' equity and related expense. We cannot predict these changes in discount rates or investment returns and, therefore, cannot reasonably estimate whether the impact in subsequent years will be significant.

The funded status of our pension plans is the difference between the projected benefit obligation and the fair value of its plan assets. The projected benefit obligation is the actuarial present value of all benefits expected to be earned by the employees' service. No compensation increase is assumed in the calculation of the projected benefit obligation, as the plans were frozen effective December 31, 2008. Further information regarding the funded status of our pension plans can be found in Note 14, “Benefit Plans,” to the consolidated financial statements in Item 8 of this Annual Report on Form 10-K.

Our funding policy for our pension plans is to contribute amounts at least equal to the minimum annual amount required by applicable regulations. Given this policy, we expect to make $0.3 million in contributions to our pension plans in 2018, at a minimum.

Income Taxes

We account for income taxes in accordance with ASC 740, Income Taxes. Our estimate of income taxes payable, deferred income taxes and the effective tax rate is based on an analysis of many factors including interpretations of federal, state and international income tax laws; the difference between tax and financial reporting bases of assets and liabilities; estimates of amounts currently due or owed in various jurisdictions; and current accounting standards. We review and update our estimates on a quarterly basis as facts and circumstances change and actual results are known.

In assessing the realizability of the deferred tax assets on our balance sheet, we consider whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the years in which those temporary differences become deductible. We consider the taxable income in prior carryback years, scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment.

Refer to Note 13, “Income Taxes” to the consolidated financial statements in Item 8 of this Annual Report on Form 10-K for further information on the Company’s income taxes and the impact of the Tax Act.

New Accounting Standards

For information with respect to new accounting pronouncements and the impact of these pronouncements on our consolidated financial statements, refer to Note 2, “Significant Accounting Policies - New Accounting Pronouncements,” to the consolidated financial statements in Item 8 of this Annual Report on Form 10-K.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risk from changes in foreign currency exchange rates, commodity prices and interest rates. To reduce the risk from these changes, we use financial instruments from time to time. We do not hold or issue financial instruments for trading purposes.

Foreign Currency

We are exposed to foreign currency exchange risk as a result of transactions denominated in currencies other than the U.S. Dollar, as well as operating businesses in foreign countries. Periodically, we utilize foreign currency forward purchase and sales contracts to manage the volatility associated with certain foreign currency purchases and sales in the normal course of business. Contracts typically have maturities of twelve months or less. Realized gains and losses on transactions denominated in foreign currency are recorded as a component of cost of goods sold on the statements of comprehensive income.

The following is a summary of the twenty-eight foreign currency contracts outstanding as of December 31, 2017 (in thousands):

Currency Denomination	Trade Dates	Effective Dates	Notional Amount	Expiration Date
GBP	9/26/17 - 12/20/17	9/26/17 - 12/20/17	14,756	1/10/18 - 3/17/18

35

Commodity Prices

We are a purchaser of commodities and of components manufactured from commodities including steel, aluminum, copper and others. As a result, we are exposed to fluctuating market prices for those commodities. While such materials are typically available from numerous suppliers, commodity raw materials are subject to price fluctuations. We generally buy these commodities and components based upon market prices that are established with the supplier as part of the purchase process. Depending on the supplier, these market prices may reset on a periodic basis based on negotiated lags and calculations. To the extent that commodity prices increase and we do not have firm pricing from our suppliers, or our suppliers are not able to honor such prices, we may experience a decline in our gross margins to the extent we are not able to increase selling prices of our products or obtain manufacturing efficiencies or supply chain savings to offset increases in commodity costs.

Periodically, we engage in certain commodity risk management activities to mitigate the impact of potential price fluctuations on our financial results. These derivatives typically have maturities of less than eighteen months. As of December 31, 2017, we had the following commodity forward contract outstanding (in thousands):

Hedged Item	Contract Date	Effective Date	Notional Amount		Fixed Price (per LB)		Expiration Date
Copper	October 19, 2016	October 20, 2016	$	3,502	$	2.118	December 31, 2017

Interest Rates

As of December 31, 2017, all of the outstanding debt under our Term Loan was subject to floating interest rate risk. As of December 31, 2017, we had the following interest rate swap contracts outstanding (in thousands):

At December 31, 2017, the fair value of these interest rate swaps was an asset of $4.4 million. Even after giving effect to these swaps, we are exposed to risks due to changes in interest rates with respect to the portion of our Term Loan that is not covered by the swaps. A hypothetical change in the LIBOR interest rate of 100 basis points would have changed annual cash interest expense by approximately $6.3 million (or, without the swaps in place, $9.3 million) in 2017. 

For additional information on the Company’s foreign currency and commodity forward contracts, and interest rate swaps, including amounts charged to the statement of comprehensive income during 2017, refer to Note 4, “Derivative Instruments and Hedging Activities,” and Note 5, “Accumulated Other Comprehensive Loss,” to our consolidated financial statements in Item 8 of this Annual Report on Form 10-K.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors of Generac Holdings Inc.

Waukesha, Wisconsin

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Generac Holdings Inc. and its subsidiaries (the "Company") as of December 31, 2017, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

Basis for Opinion

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

Definition and Limitations of Internal Control over Financial Reporting

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

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

Generac Holdings Inc.
Notes to Consolidated Financial Statements

Years Ended December 31, 2017, 2016, and 2015

(U.S. Dollars in Thousands, Except Share and Per Share Data)

1. Description of Business

Founded in 1959, Generac Holdings Inc. (the Company) is a leading global designer and manufacturer of a wide range of power generation equipment and other engine powered products serving the residential, light-commercial and industrial markets. Generac’s power products are available globally through a broad network of independent dealers, distributors, retailers, wholesalers and equipment rental companies, as well as sold direct to certain end user customers.

Over the years, the Company has executed a number of acquisitions that support its strategic plan (refer to Item 1 in this Annual Report on Form 10-K for discussion of our Powering Ahead strategic plan). A summary of recent acquisitions include the following:

● In August 2013, the Company acquired the equity of Tower Light SRL and its wholly-owned subsidiaries (Tower Light). Headquartered outside Milan, Italy, Tower Light is a leading developer and supplier of mobile light towers throughout the world.

● In November 2013, the Company purchased the assets of Baldor Electric Company’s generator division (Baldor Generators). Baldor Generators offers a complete line of power generation equipment throughout North America with power output up to 2.5MW, which expanded the Company’s commercial and industrial product lines.

● In September 2014, the Company acquired the equity of Pramac America LLC (Powermate), resulting in the ownership of the Powermate trade name and the right to license the DeWalt brand name for certain residential engine powered tools. This acquisition expanded Generac’s residential product portfolio in the portable generator category.

● In October 2014, the Company acquired MAC, Inc. (MAC). MAC is a leading manufacturer of premium-grade commercial and industrial mobile heaters for the United States and Canadian markets. The acquisition expanded the Company’s portfolio of mobile power products and provides increased access to the oil & gas market.

● In August 2015, the Company acquired Country Home Products and its subsidiaries (CHP). CHP is a leading manufacturer of high-quality, innovative, professional-grade engine powered equipment used in a wide variety of property maintenance applications, which are primarily sold in North America under the DR® Power Equipment brand. The acquisition provided an expanded product lineup and additional scale to the Company’s residential engine powered products.

● In March 2016, the Company acquired a majority ownership interest in PR Industrial S.r.l and its subsidiaries (Pramac). Headquartered in Siena, Italy, Pramac is a leading global manufacturer of stationary, mobile and portable generators primarily sold under the Pramac® brand. Pramac products are sold in over 150 countries through a broad distribution network.

Motortech is a leading manufacturer of gaseous-engine control systems and accessories, which are sold primarily to European gas-engine manufacturers and to aftermarket customers. While the Motortech acquisition was completed in January 2017, it was funded in the fourth quarter of 2016.

2. Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its subsidiaries that are consolidated in conformity with U.S. GAAP. All intercompany amounts and transactions have been eliminated in consolidation.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.

Concentration of Credit Risk

The Company maintains the majority of its domestic cash in one commercial bank in multiple operating and investment accounts. Balances on deposit are insured by the Federal Deposit Insurance Corporation (FDIC) up to specified limits. Balances in excess of FDIC limits are uninsured.

44

One customer accounted for approximately 7% and 9% of accounts receivable at December 31, 2017 and 2016, respectively. No one customer accounted for greater than 6%, 7% and 7%, of net sales during the years ended December 31, 2017, 2016, or 2015, respectively.

Accounts Receivable

Receivables are recorded at their face value amount less an allowance for doubtful accounts. The Company estimates and records an allowance for doubtful accounts based on specific identification and historical experience. The Company writes off uncollectible accounts against the allowance for doubtful accounts after all collection efforts have been exhausted. Sales are generally made on an unsecured basis.

Inventories

Inventories are stated at the lower of cost or market, with cost determined generally using the first-in, first-out method.

Property and Equipment

Property and equipment are recorded at cost and are being depreciated using the straight-line method over the estimated useful lives of the assets, which are summarized below (in years). Costs of leasehold improvements are amortized over the lesser of the term of the lease (including renewal option periods) or the estimated useful lives of the improvements.

Land improvements	8	–	20
Buildings and improvements	10	–	40
Machinery and equipment	3	–	15
Dies and tools	3	–	10
Vehicles	3	–	6
Office equipment and systems	3	–	15
Leasehold improvements	2	–	20

Total depreciation expense was $23,127, $21,465, and $16,742 for the years ended December 31, 2017, 2016, and 2015, respectively.

Goodwill and Other Indefinite-Lived Intangible Assets

Goodwill represents the excess of the purchase price over fair value of identifiable net assets acquired from business acquisitions. Goodwill is not amortized, but is reviewed for impairment on an annual basis and between annual tests if indicators of impairment are present. The Company evaluates goodwill for impairment annually as of October 31 or more frequently when an event occurs or circumstances change that indicates the carrying value may not be recoverable. The Company has the option to assess goodwill for impairment by performing either a qualitative assessment or quantitative test. The qualitative assessment determines whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then the quantitative test is not required to be performed. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company is required to perform the quantitative test. In the quantitative test, the calculated fair value of the reporting unit is compared to its book value including goodwill. If the fair value of the reporting unit is in excess of its book value, the related goodwill is not impaired. If the fair value of the reporting unit is less than its book value, an impairment loss is recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit.

Other indefinite-lived intangible assets consist of certain tradenames. The Company tests the carrying value of these tradenames annually as of October 31 or more frequently when an event occurs or circumstances change that indicates the carrying value may not be recoverable by comparing the assets’ fair value to its carrying value. Fair value is measured using a relief-from-royalty approach, which assumes the fair value of the tradename is the discounted cash flows of the amount that would be paid had the Company not owned the tradename and instead licensed the tradename from another company.

The Company performed the required annual impairment tests for goodwill and other indefinite-lived intangible assets for the fiscal years 2017, 2016 and 2015, and found no impairment following the 2017 and 2016 tests. There were no reporting units with a carrying value at-risk of exceeding fair value as of the October 31, 2017 impairment test date.

45

After performing the impairment tests for fiscal year 2015, the Company determined that the fair value of the Ottomotores reporting unit was less than its carrying value, resulting in a non-cash goodwill impairment charge in the fourth quarter of 2015 of $4,611 to write-down the balance of the Ottomotores goodwill. The decrease in fair value of the Ottomotores reporting unit was due to several factors in the second half of 2015: the continued challenges of the Latin American economies, devaluation of the Peso against the U.S. Dollar, the slow development of Mexican energy reform as a result of decreasing oil prices; combining to cause 2015 results to fall short of prior expectations and future forecasts to decrease. The fair value was determined using a discounted cash flow analysis, which utilized key financial assumptions including the sales growth factors discussed above, a 3% terminal growth rate and a 15.7% discount rate.

In the fourth quarter of 2015, the Company’s Board of Directors approved a plan to strategically transition and consolidate certain of the Company’s brands acquired in acquisitions to the Generac® tradename. This brand strategy change resulted in a reclassification to a two year remaining useful life for the impacted tradenames, causing the fair value to be less than the carrying value using the relief-from-royalty approach in a discounted cash flow analysis. As such, a $36,076 non-cash impairment charge was recorded to write-down the impacted tradenames to net realizable value.

Other than the impairment charges discussed above, the Company found no other impairment when performing the required annual impairment tests for goodwill and other indefinite-lived intangible assets for fiscal year 2015. There can be no assurance that future impairment tests will not result in a charge to earnings.

Impairment of Long-Lived Assets

The Company periodically evaluates the carrying value of long-lived assets (excluding goodwill and indefinite-lived tradenames). Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the sum of the expected future undiscounted cash flows is less than the carrying amount of an asset, a loss is recognized for the difference between the fair value and carrying value of the asset.

Debt Issuance Costs

Debt discounts and direct costs incurred in connection with the issuance of long-term debt are deferred and recorded as a reduction of outstanding debt and amortized to interest expense using the effective interest method over the terms of the related credit agreements. $3,516, $3,939, and $5,429 of deferred financing costs and original issue discount were amortized to interest expense during fiscal years 2017, 2016 and 2015, respectively. Excluding the impact of any future long-term debt issuances or prepayments, estimated amortization to interest expense for the next five years is as follows: 2018 - $4,798; 2019 - $4,982; 2020 - $4,936; 2021 - $4,931; 2022 - $5,099.

Income Taxes

The Company is a C Corporation and therefore accounts for income taxes pursuant to the liability method. Accordingly, the current or deferred tax consequences of a transaction are measured by applying the provision of enacted tax laws to determine the amount of taxes payable currently or in future years. Deferred income taxes are provided for temporary differences between the income tax bases of assets and liabilities and their carrying amounts for financial reporting purposes. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the years in which those temporary differences become deductible. The Company considers taxable income in prior carryback years, the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies, as appropriate, in making this assessment.

Revenue Recognition

Sales, net of estimated returns and allowances, are recognized upon shipment of product to the customer, which is generally when title passes, the Company has no further obligations, and the customer is required to pay subject to agreed upon payment terms. The Company, at the request of certain customers, will warehouse inventory billed to the customer but not delivered. Unless all revenue recognition criteria have been met, the Company does not recognize revenue on these transactions until the customers take possession of the product. In these cases, the funds collected on product warehoused for these customers are recorded as a customer advance until the customer takes possession of the product and the Company’s obligation to deliver the goods is completed. Customer advances are included in accrued liabilities in the consolidated balance sheets.

The Company provides for certain estimated sales programs, discounts and incentive expenses which are recognized as a reduction of sales.

46

Shipping and Handling Costs

Shipping and handling costs billed to customers are included in net sales, and the related costs are included in cost of goods sold in the consolidated statements of comprehensive income.

Advertising and Co-Op Advertising

Expenditures for advertising, included in selling and service expenses in the consolidated statements of comprehensive income, are expensed as incurred. Total expenditures for advertising were $45,926, $45,488, and $39,258 for the years ended December 31, 2017, 2016, and 2015, respectively.

Research and Development

The Company expenses research and development costs as incurred. Total expenditures incurred for research and development were $42,925, $37,229, and $32,922 for the years ended December 31, 2017, 2016 and 2015, respectively.

Foreign Currency Translation and Transactions

Balance sheet amounts for non-U.S. Dollar functional currency businesses are translated into U.S. Dollars at the rates of exchange in effect at the end of the fiscal year. Income and expenses incurred in a foreign currency are translated at the average rates of exchange in effect during the year. The related translation adjustments are made directly to accumulated other comprehensive loss, a component of stockholders’ equity, in the consolidated balance sheets. Gains and losses from foreign currency transactions are recognized as incurred in the consolidated statements of comprehensive income.

Fair Value of Financial Instruments

ASC 820-10, Fair Value Measurement, defines fair value, establishes a consistent framework for measuring fair value, and expands disclosure for each major asset and liability category measured at fair value on either a recurring basis or nonrecurring basis. ASC 820-10 clarifies that fair value is an exit price, representing the amount that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the pronouncement establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: (Level 1) observable inputs such as quoted prices in active markets; (Level 2) inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

The Company believes the carrying amount of its financial instruments (cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities, short-term borrowings and ABL facility borrowings), excluding Term Loan borrowings, approximates the fair value of these instruments based upon their short-term nature. The fair value of Term Loan borrowings, which have an aggregate carrying value of $902,959, was approximately $903,500 (Level 2) at December 31, 2017, as calculated based on independent valuations whose inputs and significant value drivers are observable.

For the fair value of the assets and liabilities measured on a recurring basis, refer to the fair value table in Note 4, “Derivative Instruments and Hedging Activities,” to the consolidated financial statements. The fair value of all derivative contracts is classified as Level 2. The valuation techniques used to measure the fair value of derivative contracts, all of which have counterparties with high credit ratings, were based on quoted market prices or model driven valuations using significant inputs derived from or corroborated by observable market data. The fair value of derivative contracts considers the Company’s credit risk in accordance with ASC 820-10.

Use of Estimates

The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Derivative Instruments and Hedging Activities

The Company records all derivatives in accordance with ASC 815, Derivatives and Hedging, which requires derivative instruments be reported on the consolidated balance sheets at fair value and establishes criteria for designation and effectiveness of hedging relationships. The Company is exposed to market risk such as changes in commodity prices, foreign currencies and interest rates. The Company does not hold or issue derivative financial instruments for trading purposes.

47

Share-Based Compensation

Share-based compensation expense, including stock options and restricted stock awards, is generally recognized on a straight-line basis over the vesting period based on the fair value of awards which are expected to vest. The fair value of all share-based awards is estimated on the date of grant.

New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers. This guidance is the culmination of the FASB’s joint project with the International Accounting Standards Board to clarify the principles for recognizing revenue. The core principal of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance provides a five-step process that entities should follow in order to achieve that core principal. ASU 2014-09, as amended by ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations, ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, and ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, becomes effective for the Company in 2018. The guidance can be applied either on a full retrospective basis or on a modified retrospective basis in which the cumulative effect of initially applying the standard is recognized at the date of initial application. The Company has completed its assessment of the impacts the standard will have on its financial statements, and determined that the adoption does not have a material impact. In all material respects, the Company has identified a similar amount of performance obligations under the new guidance as compared with deliverables previously identified. As a result, the timing of revenue recognition will generally remain the same. The Company adopted the standard January 1, 2018 and will use the full retrospective method.

In February 2016, the FASB issued ASU 2016-02, Leases. This guidance is being issued to increase transparency and comparability among organizations by requiring the recognition of lease assets and lease liabilities on the balance sheet and by disclosing key information about leasing arrangements. The guidance should be applied using a modified retrospective approach and is effective for the Company in 2019, with early adoption permitted. The Company is currently assessing the impact the adoption of this guidance will have on the Company’s results of operations and financial position.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments. This guidance is being issued to decrease diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This guidance should be applied on a retrospective basis and is effective for the Company in 2018, with early adoption permitted. The Company does not believe that the adoption of this guidance will have a significant impact on the presentation of the statement of cash flows.

In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other: Simplifying the Test for Goodwill Impairment. This guidance was issued to simplify the subsequent measurement of goodwill by eliminating Step 2 of the goodwill impairment test. Under the new guidance, the recognition of a goodwill impairment charge is calculated based on the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. This guidance should be applied on a prospective basis and is effective for the Company in 2020. The Company has early adopted this standard, which did not have a significant impact on its consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging – Targeted Improvements to Accounting for Hedging Activities. This guidance was issued 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, and to make certain targeted improvements to simplify the application of the hedge accounting guidance. For existing hedges, this guidance should be applied using a cumulative effect adjustment, while the presentation and disclosure guidance should be adopted on a prospective basis. The standard is effective for the Company in 2019, with early adoption permitted. The Company is currently assessing the impact the adoption of this guidance will have on the Company’s results of operations and financial position.

48

In the first quarter of 2017, the Company adopted ASU 2016-09, Compensation – Stock Compensation: Improvements to Employee Share-Based Payment Accounting. The primary impact of adoption is the prospective recognition of excess tax benefits or deficiencies within the provision for income taxes on the consolidated statement of comprehensive income rather than within additional paid-in capital on the consolidated balance sheet. Further, the Company has elected to continue to estimate forfeitures expected to occur to determine the amount of stock compensation expense recognized each period. The Company also elected to apply the presentation requirements for cash flows related to excess tax benefits or deficiencies prospectively. The presentation requirements for cash flows related to employee taxes paid in exchange for withheld shares had no impact to any period presented on the consolidated statements of cash flows as such cash flows have historically been presented as a financing activity. There were no cumulative effect adjustments made to equity as of the beginning of the fiscal period, as those provisions of ASU 2016-09 were not applicable or had no impact to the Company.

There are several other new accounting pronouncements issued by the FASB. Each of these pronouncements, as applicable, has been or will be adopted by the Company. Management does not believe any of these accounting pronouncements has had or will have a material impact on the Company’s consolidated financial statements.

3. Acquisitions

Acquisition of Pramac

On March 1, 2016, the Company acquired a 65% ownership interest in Pramac for a purchase price, net of cash acquired, of $60,250. Headquartered in Siena, Italy, Pramac is a leading global manufacturer of stationary, mobile and portable generators primarily sold under the Pramac® brand. Pramac products are sold in over 150 countries through a broad distribution network. The acquisition purchase price was funded solely through cash on hand.

The 35% noncontrolling interest in Pramac had an acquisition date fair value of $34,253, and was recorded as a redeemable noncontrolling interest in the consolidated balance sheet, as the noncontrolling interest holder has within its control the right to require the Company to redeem its interest in Pramac. The noncontrolling interest holder has a put option to sell their interests to the Company any time within five years from the date of acquisition. The put option price is either (i) a fixed amount if voluntarily exercised within the first two years after the acquisition, or (ii) based on a multiple of earnings, subject to the terms of the acquisition. Additionally, the Company holds a call option that it may redeem commencing five years from the date of acquisition, or earlier upon the occurrence of certain circumstances. The call option price is based on a multiple of earnings that is subject to the terms of the acquisition. Both the put and call option only provide for the complete transfer of the noncontrolling interest, with no partial transfers of interest permitted.

The redeemable noncontrolling interest is recorded at the greater of the initial fair value, increased or decreased for the noncontrolling interests’ share of comprehensive net income (loss), or the estimated redemption value, with any adjustment to the redemption value impacting retained earnings, but not net income. However, the redemption value adjustments are reflected in the earnings per share calculation, as detailed in Note 12, “Earnings Per Share,” to the consolidated financial statements. The following table presents the changes in the redeemable noncontrolling interest:

	Year Ended December 31,
	2017			2016
Balance at beginning of period	$	33,138		$	-
Noncontrolling interest of Pramac		1,540	(1)		34,253
Net income		1,631			100
Foreign currency translation		8,529			(2,124	)
Redemption value adjustment		(909	)		909
Balance at end of period	$	43,929		$	33,138

Acquisition of CHP

On August 1, 2015, the Company acquired CHP for a purchase price, net of cash acquired, of $74,570. Headquartered in Vergennes, Vermont, CHP is a leading manufacturer of high-quality, innovative, professional-grade engine powered equipment used in a wide variety of property maintenance applications, with sales primarily in North America. The acquisition purchase price was funded solely through cash on hand.

The Company finalized the CHP purchase price allocation during the fourth quarter of 2015 based upon its estimates of the fair value of the acquired assets and assumed liabilities. As a result, the Company recorded approximately $75,174 of intangible assets, including approximately $36,284 of goodwill, as of the acquisition date. The goodwill ascribed to this acquisition is not deductible for tax purposes. In addition, the Company assumed $12,000 of debt along with this acquisition. The accompanying consolidated financial statements include the results of CHP from the date of acquisition through December 31, 2017.

Pro Forma Information

The following unaudited pro forma information of the Company gives effect to these acquisitions as though the transactions had occurred on January 1, 2015. Consolidated net sales on a pro forma basis for the years ended December 31, 2016 and 2015 were $1,473,799 and $1,566,459, respectively. The pro forma impact of these acquisitions on net income and earnings per share for both the years ended December 31, 2016 and 2015 is not significant due to amortization related to acquired intangible assets and the fair value step-up of inventory in purchase accounting. This unaudited pro forma information is presented for informational purposes only and is not necessarily indicative of the results of operations that actually would have been achieved had the acquisitions been consummated on January 1, 2015.

4. Derivative Instruments and Hedging Activities

Commodities

The Company is exposed to price fluctuations in commodities it uses as raw materials; primarily steel, copper and aluminum; and periodically utilizes commodity derivatives to mitigate the impact of these potential price fluctuations on its financial results and its economic well-being. These derivatives typically have maturities of less than eighteen months. At both December 31, 2017 and 2016, the Company had one commodity contract outstanding, covering the purchases of copper.

Because these contracts do not qualify for hedge accounting, the related gains and losses are recorded in cost of goods sold in the Company’s consolidated statements of comprehensive income. Net pre-tax gains (losses) recognized were $377, $739 and $(1,909) for the years ended December 31, 2017, 2016, and 2015, respectively.

50

Foreign Currencies

The Company is exposed to foreign currency exchange risk as a result of transactions denominated in currencies other than the U.S. Dollar. The Company periodically utilizes foreign currency forward purchase and sales contracts to manage the volatility associated with certain foreign currency purchases and sales in the normal course of business. Contracts typically have maturities of twelve months or less. As of December 31, 2017 and 2016, the Company had twenty-eight and thirty-eight foreign currency contracts outstanding, respectively.

Because these contracts do not qualify for hedge accounting, the related gains and losses are recorded in other, net in the Company’s consolidated statements of comprehensive income. Net pre-tax gains (losses) recognized for the years ended December 31, 2017, 2016 and 2015 were $697, $(385) and $(624), respectively.

Interest Rate Swaps

In October 2013, the Company entered into two interest rate swap agreements; in May 2014, the Company entered into one interest rate swap agreement; and in 2017, the Company entered into twenty additional interest rate swap agreements. The Company formally documented all relationships between interest rate hedging instruments and the related hedged items, as well as its risk-management objectives and strategies for undertaking these hedge transactions. These interest rate swap agreements qualify as cash flow hedges, and accordingly, the effective portions of the gains or losses are reported as a component of accumulated other comprehensive loss (AOCL) in the consolidated balance sheets. The amount of gains (losses) recognized for the years ended December 31, 2017, 2016 and 2015 were $3,712, $535 and $(965), respectively. The cash flows of the swaps are recognized as adjustments to interest expense each period. The ineffective portions of the derivatives’ changes in fair value, if any, are immediately recognized in earnings.

Fair Value

The following table presents the fair value of the Company’s derivatives:

	December 31, 2017		December 31, 2016
Commodity contracts	$	107	$	623
Foreign currency contracts		167		(150	)
Interest rate swaps		4,356		(1,739	)

The fair value of the commodity and foreign currency contracts are included in prepaid expenses and other assets, and the fair value of the interest rate swaps are included in other assets in the consolidated balance sheet as of December 31, 2017. The fair value of the commodity contract is included in other assets, the fair value of the foreign currency contracts are included in other accrued liabilities, and the fair value of the interest rate swaps are included in other long-term liabilities in the consolidated balance sheet as of December 31, 2016. Excluding the impact of credit risk, the fair value of the derivative contracts as of December 31, 2017 and 2016 is an asset of $4,703 and a liability of $1,295, respectively, which represents the amount the Company would receive or need to pay to exit the agreements on those dates.

6. Segment Reporting

The Company has two reportable segments for financial reporting purposes – Domestic and International. The Domestic segment includes the legacy Generac business and the impact of acquisitions that are based in the United States, all of which have revenues that are substantially derived from the U.S. and Canada. The International segment includes the Ottomotores, Tower Light, Pramac and Motortech acquisitions, all of which have revenues that are substantially derived from outside of the U.S and Canada. Both reportable segments design and manufacture a wide range of power generation equipment and other engine powered products. The Company has multiple operating segments, which it aggregates into the two reportable segments, based on materially similar economic characteristics, products, production processes, classes of customers and distribution methods. All segment information has been retrospectively applied to all periods presented to reflect the current reportable segment structure.

9. Product Warranty Obligations

The Company records a liability for product warranty obligations at the time of sale to a customer based upon historical warranty experience. The Company also records a liability for specific warranty matters when they become known and are reasonably estimable. Additionally, the Company sells extended warranty coverage for certain products. The sales of extended warranties are recorded as deferred revenue, which is recognized over the life of the contracts following the standard warranty period.

The following is a tabular reconciliation of the product warranty liability, excluding the deferred revenue related to our extended warranty coverage:

	Year Ended December 31,
	2017			2016			2015
Balance at beginning of period	$	31,695		$	30,197		$	30,909
Product warranty reserve assumed in acquisition		43			840			351
Payments		(18,861	)		(18,691	)		(21,686	)
Provision for warranty issued		21,347			19,148			20,823

Deferred revenue contracts issued (1)		27,107			7,733			5,978
Amortization of deferred revenue contracts		(7,246	)		(5,614	)		(4,501	)
Balance at end of period	$	50,941		$	31,080		$	28,961

(1) The increase in deferred revenue contracts issued during 2017 was largely due to the launch of a post-sale extended warranty program.

Product warranty obligations and extended warranty related deferred revenues are included in the balance sheets as follows:

	December 31,
	2017		2016
Product warranty liability
Current portion - other accrued liabilities	$	20,576	$	20,763

The Company’s credit agreements originally provided for a $1,200,000 term loan B credit facility (Term Loan) and currently include a $300,000 uncommitted incremental term loan facility. In November 2016, the Company amended its Term Loan to extend the maturity date from May 31, 2020 to May 31, 2023. The Term Loan is guaranteed by all of the Company’s wholly-owned domestic restricted subsidiaries, and is secured by associated collateral agreements which pledge a first priority lien on virtually all of the Company’s assets, including fixed assets and intangibles, other than all cash, trade accounts receivable, inventory, and other current assets and proceeds thereof, which are secured by a second priority lien. The Term Loan initially bore interest at rates based upon either a base rate plus an applicable margin of 1.75% or adjusted LIBOR rate plus an applicable margin of 2.75%, subject to a LIBOR floor of 0.75%. Beginning in the second quarter of 2014, and measured each quarterly period thereafter, the applicable margin related to base rate loans was reduced to 1.50% and the applicable margin related to LIBOR rate loans is reduced to 2.50%, in each case, if the Company’s net debt leverage ratio, as defined in the Term Loan, falls below 3.00 to 1.00 for that measurement period.

Because the Company’s net debt leverage ratio was above 3.00 to 1.00 on July 1, 2015, it realized a 25 basis point increase in borrowing costs in the third quarter of 2015. As a result, the Company recorded a cumulative catch-up loss of $2,381 in the third quarter of 2015, which represented the additional cash interest expected to be paid while the net debt leverage ratio was expected to be above 3.00 to 1.00 using current forecasts at that time. The loss was recorded against original issue discount and deferred financing costs on long-term borrowings in the consolidated balance sheets and as a loss on change in contractual interest rate in the consolidated statement of comprehensive income.

As the Company’s net debt leverage ratio continued to be above 3.00 to 1.00 on July 1, 2016, the Company recorded a cumulative catch-up loss of $2,957 in the third quarter of 2016, which represented the additional cash interest expected to be paid while the net debt leverage ratio was expected to be above 3.00 to 1.00 using current forecasts at that time. The loss was recorded against original issue discount and deferred financing costs on long-term borrowings in the consolidated balance sheets and as a loss on change in contractual interest rate in the consolidated statement of comprehensive income.

In May 2015, the Company amended certain provisions and covenants of the Term Loan. In connection with this amendment and in accordance with ASC 470-50, Debt Modifications and Extinguishments, the Company capitalized $1,528 of fees paid to creditors as deferred financing costs on long-term borrowings and expensed $49 of transaction fees in the second quarter of 2015.

In November 2016, the Company amended its Term Loan to extend the maturity date from May 31, 2020 to May 31, 2023. In connection with this amendment and in accordance with ASC 470-50, the Company capitalized $4,242 of fees paid to creditors as original issue discount and deferred financing costs on long-term borrowings and expensed $315 of transaction fees in the fourth quarter of 2016.

In May 2017, the Company amended its Term Loan, modifying the pricing of the facility by reducing the applicable margin rates to base rate plus a fixed applicable margin of 1.25% or adjusted LIBOR rate plus a fixed applicable margin of 2.25%. Further, the amendment removed the pricing grid that would reduce the applicable margin if a net debt leverage ratio of 3.00 to 1.00 was achieved. As a result, the Company does not anticipate any future catch-up gains or losses resulting from changes in contractual interest rates to be recorded in the statements of comprehensive income. The amended Term Loan pricing is still subject to the 0.75% LIBOR floor. In connection with this amendment and in accordance with ASC 470-50, the Company capitalized $1,432 of fees paid to creditors as deferred financing costs on long-term borrowings and expensed $85 of transaction fees in the second quarter of 2017.

In December 2017, the Company amended its Term Loan, which further reduced the applicable margin rates to base rate plus a fixed applicable margin of 1.00% or adjusted LIBOR rate plus a fixed applicable margin of 2.00%. Additionally, the amendment eliminated the Excess Cash Flow payment requirement for 2017, and will eliminate future requirements if the Company’s secured leverage ratio is maintained below 3.75 to 1.00 times. In connection with this amendment and in accordance with ASC 470-50, the Company capitalized $2,346 of fees paid to creditors as original issue discount and deferred financing costs on long-term borrowings and expensed $38 of transaction fees in the fourth quarter of 2017.

As of December 31, 2017, the Company's secured leverage ratio was 2.50 to 1.00 times, and the Company was in compliance with all covenants of the Term Loan. There are no financial maintenance covenants on the Term Loan.

The Company’s credit agreements also originally provided for a $150,000 senior secured ABL revolving credit facility (ABL Facility). The maturity date of the ABL Facility originally was May 31, 2018. Borrowings under the ABL Facility are guaranteed by all of the Company’s wholly-owned domestic restricted subsidiaries, and are secured by associated collateral agreements which pledge a first priority lien on all cash, trade accounts receivable, inventory, and other current assets and proceeds thereof, and a second priority lien on all other assets, including fixed assets and intangibles of the Company and certain domestic subsidiaries. ABL Facility borrowings initially bore interest at rates based upon either a base rate plus an applicable margin of 1.00% or adjusted LIBOR rate plus an applicable margin of 2.00%, in each case, subject to adjustments based upon average availability under the ABL Facility.

In May 2015, the Company amended its ABL Facility (Amended ABL Facility). The amendment (i) increased the ABL Facility from $150,000 to $250,000, (ii) extended the maturity date from May 31, 2018 to May 29, 2020, (iii) increased the uncommitted incremental facility from $50,000 to $100,000, (iv) reduced the interest rate spread by 50 basis points and (v) reduced the unused line fee by 12.5 basis points across all tiers. Additionally, the amendment relaxes certain restrictions on the Company’s ability to, among other things, (i) make additional investments and acquisitions (including foreign acquisitions), (ii) make restricted payments and (iii) incur additional secured and unsecured debt (including foreign subsidiary debt). In connection with this amendment and in accordance with ASC 470-50, the Company capitalized $540 of new debt issuance costs in 2015.

In May 2015, the Company borrowed $100,000 under the Amended ABL Facility, the proceeds of which were used as a voluntary prepayment towards the Term Loan. In the fourth quarter of 2017, the Company repaid the entire outstanding Amended ABL Facility balance. As of December 31, 2017, the Company had $249,650 of availability under the Amended ABL Facility, net of outstanding letters of credit.

In March and May 2015, the Company made voluntary prepayments of the Term Loan of $50,000 and $100,000, respectively, which were applied to the Excess Cash Flow payment requirement in the Term Loan. As a result of the prepayments, the Company wrote off $4,795 of original issue discount and capitalized debt issuance costs during the year ended December 31, 2015 as a loss on extinguishment of debt in the consolidated statement of comprehensive income. Similarly, in November 2016, the Company made a voluntary prepayment of $25,000, which resulted in a $574 write-off of original issue discount and capitalized debt issuance costs during the year ended December 31, 2016 as a loss on extinguishment of debt.

As of December 31, 2017 and December 31, 2016, short-term borrowings consisted primarily of borrowings by our foreign subsidiaries on local lines of credit, which totaled $20,602 and $31,198, respectively.

11. Stock Repurchase Program

In August 2015, the Company’s Board of Directors approved a $200,000 stock repurchase program, which the Company completed in the third quarter of 2016. In October 2016, the Company’s Board of Directors approved an additional $250,000 stock repurchase program. Under the second program, the Company may repurchase up to $250,000 of its common stock over the 24 months following the date of approval. The Company may repurchase its common stock from time to time, in amounts and at prices the Company deems appropriate, subject to market conditions and other considerations. The repurchase may be executed using open market purchases, privately negotiated agreements or other transactions. The actual timing, number and value of shares repurchased under the program will be determined by management at its discretion and will depend on a number of factors, including the market price of the Company’s common stock and general market and economic conditions, applicable legal requirements, and compliance with the terms of the Company’s outstanding indebtedness. The repurchases may be funded with cash on hand, available borrowings or proceeds from potential debt or other capital markets sources. The stock repurchase program may be suspended or discontinued at any time without prior notice. During the years ended December 31, 2017, 2016 and 2015, the Company repurchased 844,500, 3,968,706 and 3,303,500 shares of its common stock, respectively, for $30,012, $149,937 and $99,942, respectively, all funded with cash on hand.

12. Earnings Per Share

Basic earnings per share is calculated by dividing net income attributable to the common shareholders of the Company by the weighted average number of common shares outstanding during the period, exclusive of restricted shares. Except where the result would be anti-dilutive, diluted earnings per share is calculated by assuming the vesting of unvested restricted stock and the exercise of stock options. The following table reconciles the numerator and the denominator used to calculate basic and diluted earnings per share:

	Year Ended December 31,
	2017		2016			2015
Numerator
Net income attributable to Generac Holdings Inc.	$	159,386	$	98,788		$	77,747

(1) Excludes approximately 147,400, 15,800 and 161,400 stock options for the years ended December 31, 2017, 2016 and 2015, respectively, as the impact of such awards was anti-dilutive. Excludes approximately 1,000 shares of restricted stock for the year ended December 31, 2015, as the impact of such awards was anti-dilutive.

13. Income Taxes

The Company’s provision for income taxes consists of the following:

	Year Ended December 31,
	2017			2016			2015
Current:
Federal	$	15,753		$	11,717		$	13,614

Change in valuation allowance		2,454			638			138
Provision for income taxes	$	43,553		$	57,570		$	45,236

The Company files U.S federal, U.S. state and foreign jurisdiction tax returns that are subject to examination up to the expiration of the statute of limitations. We believe the tax positions taken on our returns would be sustained upon an exam, or where a position is uncertain, adequate reserves have been recorded. As of December 31, 2017 the Company is no longer subject to income tax examinations for United States federal income taxes for the tax years prior to 2014. Due to the carryforward of net operating losses, and research and development credits, the Company's Wisconsin state income tax returns for tax years 2007 through 2016 remain open. In addition, the Company is subject to audit by various foreign taxing jurisdictions for the tax years 2012 through 2016.

The Company is currently under examination in multiple jurisdictions and is working to address all matters. While the Company does not believe any material taxes or penalties are due, there is a possibility that the ultimate tax outcome of an examination may result in differences from what was recorded. Such differences may affect the provision for income taxes in the period in which the determination is made, and could impact the Company’s financial results.

59

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act makes broad and complex changes to the U.S. tax code, including, but not limited to, reducing the U.S. federal corporate tax rate from 35% to 21%, requiring companies to pay a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries, eliminating certain deductions, introducing new tax regimes, changing how foreign earnings are subject to U.S. tax, and enhancing and extending through 2026 the option to claim accelerated depreciation deductions on qualified property.

The SEC staff issued SAB 118, which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act.

The Company's accounting for the following elements of the Tax Act is incomplete. However, reasonable estimates of certain effects were able to be made and, therefore, provisional adjustments were recorded as follows:

Reduction of US federal corporate tax rate: The Tax Act reduces the federal corporate tax rate to 21%, effective January 1, 2018. For certain of the Company's deferred tax liabilities (DTLs), a provisional decrease of $28,434 was recorded to reflect our DTLs at thelower corporate tax rate, with a corresponding net adjustment to deferred income tax benefit of $28,434 for the year ended December 31, 2017. While a reasonable estimate of the impact of the reduction in the corporate tax rate was made, it may be affected by other analyses related to the Tax Act, including, but not limited to, the calculation of deemed repatriation of deferred foreign income and the state tax effect of adjustments made to federal temporary differences.

Deemed Repatriation Transition Tax:The Deemed Repatriation Transition Tax (Transition Tax) is a tax on previously untaxed accumulated and current earnings and profits (E&P) of certain of the Company’s foreign subsidiaries. To determine the amount of the Transition Tax, the amount of post-1986 E&P of relevant subsidiaries, as well as the amount of non-U.S. income taxes paid on such earnings must be determined, in addition to other factors. The Company made a reasonable estimate of the Transition Tax and has concluded the amount was not material.

Cost recovery: While the Company has not yet completed all of the computations necessary or completed an inventory of our 2017 expenditures that qualify for immediate expensing, a provisional benefit of $700 was recorded based on our current intent to fully expense all qualifying expenditures. This resulted in a decrease of approximately $1,750 to current income tax payable and a corresponding increase in DTLs of approximately $1,050 (after considering the effects of the reduction in income tax rates).

As the Company completes its analysis of the Tax Act; collects and prepares necessary data; and interprets any additional guidance issued by the U.S. Treasury Department, the IRS, and other standard-setting bodies; adjustments to the provisional amounts may be recorded.

Global intangible low taxed income (GILTI): Because of the complexity of the new GILTI tax rules, the Company is continuing to evaluate this provision of the Tax Act and the application of ASC 740. Under U.S. GAAP, the Company is allowed to make an accounting policy choice of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the “period cost method”) or (2) factoring such amounts into a company’s measurement of its deferred taxes (the “deferred method”). The selection of an accounting policy with respect to the new GILTI tax rules will depend, in part, on analyzing the Company's global income to determine whether it is expected to have future U.S. inclusions in taxable income related to GILTI and, if so, what the impact is expected to be. Because whether the Company expects to have future U.S. inclusions in taxable income related to GILTI depends not only on the current structure and estimated future results of global operations but also on the intent and ability to modify the structure and/or the business; the Company is not yet able to reasonably estimate the effect of this provision of the Tax Act. Therefore, no adjustments related to potential GILTI tax have been made in the financial statements and no policy decision regarding whether to record deferred taxes on GILTI has been made.

Significant components of deferred tax assets and liabilities are as follows:

	December 31,
	2017			2016
Deferred tax assets:
Accrued expenses	$	15,138		$	22,758
Deferred revenue		8,060			10,645
Inventories		7,933			10,159
Pension obligations		3,795			7,512
Stock-based compensation		5,522			7,291
Operating loss and credit carryforwards		23,771			20,927
Other		1,064			2,822
Valuation allowance		(6,817	)		(4,362	)
Total deferred tax assets		58,466			77,752
Deferred tax liabilitites:
Goodwill and intangible assets		70,556			58,133
Depreciation		22,563			25,194
Debt refinancing costs		5,189			7,193
Prepaid expenses		709			1,173
Total deferred tax liabilities		99,017			91,693
Net deferred tax liabilities	$	(40,551	)	$	(13,941	)

As of December 31, 2017 and 2016, deferred tax assets of $3,238 and $3,337, and deferred tax liabilities of $43,789 and $17,278, respectively, were reflected on the consolidated balance sheets.

One of the Company's subsidiaries, Generac Brazil, has generated net operating losses for multiple years. The realizability of the deferred tax assets associated with these net operating losses is uncertain, therefore a valuation allowance has been recorded since Generac Brazil's acquisition on December 8, 2012 and continued through December 31, 2017.

In addition, the Company recorded a valuation allowance in the opening balance sheet and as of December 31, 2017 and 2016 related to the Pramac acquisition. The valuation allowance represents a reserve for deferred tax assets, including loss carryforwards, of certain Pramac subsidiaries, for which utilization is uncertain.

At December 31, 2017, the Company had state research and development tax credit carryforwards, and state manufacturing tax credit carryforwards of approximately $13,089 and $4,618, respectively, which expire between 2018 and 2032. A valuation allowance of $1,171 has been established against deferred tax assets for these carryforwards.

Changes in the Company’s gross liability for unrecognized tax benefits, excluding interest and penalties, were as follows:

	December 31,
	2017			2016
Unrecognized tax benefit, beginning of period	$	7,943		$	7,239
Increase in unrecognized tax benefit for positions taken in current period		251			704
Statute of limitation expirations		(1,072	)		-
Unrecognized tax benefit, end of period	$	7,122		$	7,943

The unrecognized tax benefit as of  December 31, 2017 and 2016, if recognized, would impact the effective tax rate.

As of  December 31, 2017, 2016 and 2015, total accrued interest of approximately $131, $272 and $174, respectively, and accrued penalties of approximately $220, $425 and $363, respectively, associated with net unrecognized tax benefits are included in the Company’s consolidated balance sheets. Interest and penalties are recorded as a component of income tax expense.

61

The Company does not expect a significant increase or decrease to the total amounts of unrecognized tax benefits related to continuing operations during the fiscal year ending December 31, 2018.

The Tax Act includes a mandatory one-time tax on accumulated earnings of foreign subsidiaries, and as a result, all previously unremitted earnings for which no U.S. deferred tax liability had been accrued have now been subject to U.S. tax. Notwithstanding the U.S. taxation of these amounts, the Company intends to continue to invest these earnings, as well as the capital in these subsidiaries, indefinitely outside of the U.S. and do not expect to incur any significant, additional taxes related to such amounts.

A reconciliation of the statutory tax rates and the effective tax rates for the years ended December 31, 2017, 2016 and 2015 are as follows:

	Year Ended December 31,
	2017			2016			2015
U.S. statutory rate		35.0	%		35.0	%		35.0	%
State taxes		4.1			4.1			4.1
Research and development credits		(1.4	)		(1.0	)		(2.3	)
Share-based compensation (1)		(1.4	)		-			-
Tax Act impact		(13.9	)		-			-
Other		(1.1	)		(1.3	)		-
Effective tax rate		21.3	%		36.8	%		36.8	%

(1) With the adoption of ASU 2016-09 in the first quarter of 2017, excess tax benefits from equity awards are reflected within the provision for income taxes rather than within the consolidated balance sheet. For further information on the Company’s adoption of ASU 2016-09, refer to Note 2, “Significant Accounting Policies – New Accounting Pronouncements” to the consolidated financial statements.

14. Benefit Plans

Medical and Dental Plan

The Company maintains medical and dental benefit plans covering its full-time domestic employees and their dependents. Certain plans are partially or fully self-funded under which participant claims are obligations of the plan. These plans are funded through employer and employee contributions at a level sufficient to pay for the benefits provided by the plan. The Company’s contributions to the plans were $14,992, $15,019, and $14,352 for the years ended December 31, 2017, 2016, and 2015, respectively.

The Company’s foreign subsidiaries participate in government sponsored medical benefit plans. In certain cases, the Company purchases supplemental medical coverage for certain employees at these foreign locations. The expenses related to these plans are not material to the Company’s consolidated financial statements.

Savings Plan

The Company maintains a defined-contribution 401(k) savings plan for eligible domestic employees. Under the plan, employees may defer receipt of a portion of their eligible compensation. The Company amended the 401(k) savings plans effective January 1, 2009, to add Company matching and non-elective contributions. The Company may contribute a matching contribution of 50% of the first 6% of eligible compensation of employees. The Company may also contribute a non-elective contribution for eligible employees employed on December 31, 2008. Both Company matching contributions and non-elective contributions are subject to vesting. Forfeitures may be applied against plan expenses and company contributions. The Company recognized $3,600, $3,400 and $3,000 of expense related to these plans in 2017, 2016 and 2015, respectively.

Pension Plans

The Company has frozen noncontributory salaried and hourly pension plans (Pension Plans) covering certain domestic employees. The Pension Plans were frozen effective December 31, 2008. The benefits under the salaried plan are based upon years of service and the participants’ defined final average monthly compensation. The benefits under the hourly plan are based on a unit amount at the date of termination multiplied by the participant’s years of credited service. The Company’s funding policy for the Pension Plans is to contribute amounts at least equal to the minimum annual amount required by applicable regulations.

62

The Company uses a December 31 measurement date for the Pension Plans. The accumulated benefit obligation, reconciliation of the changes in projected benefit obligation, changes in plan assets and the funded status of the Pension Plans are as follows:

	Year Ended December 31,
	2017			2016
Accumulated benefit obligation at end of period	$	72,631		$	65,956
Change in projected benefit obligation
Projected benefit obligation at beginning of period	$	65,956		$	63,894
Interest cost		2,688			2,747
Net actuarial loss		6,170			1,363
Benefits paid		(2,183	)		(2,048	)
Projected benefit obligation at end of period	$	72,631		$	65,956
Change in plan assets
Fair value of plan assets at beginning of period	$	46,488		$	43,985
Actual return on plan assets		8,382			3,820
Company contributions		5,327			731
Benefits paid		(2,183	)		(2,048	)
Fair value of plan assets at end of period	$	58,014		$	46,488
Funded status: accrued pension liability included in other long-term liabilities	$	(14,617	)	$	(19,468	)
Amounts recognized in accumulated other comprehensive loss
Net actuarial loss, net of tax	$	(10,978	)	$	(11,040	)

The actuarial loss for the Pension Plans that was amortized from AOCL into net periodic (benefit) cost during 2017 is $883. The amount in AOCL as of December 31, 2017 that is expected to be recognized as a component of net periodic pension expense during the next fiscal year is $802.

The components of net periodic pension cost are as follows:

	Year Ended December 31,
	2017			2016			2015
Interest cost	$	2,688		$	2,747		$	2,681
Expected return on plan assets		(3,011	)		(2,868	)		(3,041	)
Amortization of net loss		883			941			1,228
Net periodic pension cost	$	560		$	820		$	868

Weighted-average assumptions used to determine the benefit obligations are as follows:

	December 31,
	2017			2016
Discount rate – salaried pension plan		3.60	%		4.14	%
Discount rate – hourly pension plan		3.62	%		4.16	%
Rate of compensation increase (1)		n/a			n/a

(1) No compensation increase was assumed as the plans were frozen effective December 31, 2008.

63

Weighted-average assumptions used to determine net periodic pension cost are as follows:

	Year Ended December 31,
	2017			2016			2015

(1) No compensation increase was assumed as the plans were frozen effective December 31, 2008.

To determine the long-term rate of return assumption for the plans' assets, the Company studies historical markets and preserves the long-term historical relationships between equities and fixed-income securities consistent with the widely accepted capital market principle that assets with higher volatility generate a greater return over the long run. The Company evaluates current market factors such as inflation and interest rates before it determines long-term capital market assumptions and reviews peer data and historical returns to check for reasonableness and appropriateness.

The Pension Plans’ weighted-average asset allocation at December 31, 2017 and 2016, by asset category, is as follows:

	Target Allocation				December 31, 2017					December 31, 2016
Asset Category	Minimum		Maximum		Dollars		%			Dollars		%
Fixed Income	15.0	%	25.0	%	$	10,637		18	%	$	7,812		17	%

The fair values of the Pension Plans’ assets at December 31, 2017 are as follows:

	Total		Quoted Prices in Active Markets for Identical Asset (Level 1)		Significant Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

Mutual Funds – This category includes investments in mutual funds that encompass both equity and fixed income securities that are designed to provide a diverse portfolio. The plans' mutual funds are designed to track exchange indices, and invest in diverse industries. Some mutual funds are classified as regulated investment companies. Investment managers have the ability to shift investments from value to growth strategies, from small to large capitalization funds, and from U.S. to international investments. These investments are valued at the closing price reported on the active market on which the individual securities are traded. These investments are classified within Level 1 of the fair value hierarchy.

Other Investments – This category includes investments in limited partnerships and are valued at estimated fair value, as determined with the assistance of each respective limited partnership, based on the net asset value of the investment as of the balance sheet date, which is subject to judgment, and therefore is classified within Level 3 of the fair value hierarchy.

The Company’s target allocation for equity securities and real estate is generally between 65% - 85%, with the remainder allocated primarily to fixed income (bonds). The Company regularly reviews its actual asset allocation and periodically rebalances its investments to the targeted allocation when considered appropriate.

At a minimum, the Company expects to make estimated contributions of $319 to the Pension Plans in 2018.

The following benefit payments are expected to be paid from the Pension Plans:

2018	$	2,445
2019		2,502
2020		2,622
2021		2,760
2022		2,932
2023 – 2027		16,989

Certain of the Company’s foreign subsidiaries participate in local statutory defined benefit or other post-employment benefit plans. These plans provide benefits that are generally based on years of credited service and a percentage of the employee’s eligible compensation earned throughout the applicable service period. Liabilities recorded under these plans are included in accrued wages and employee benefits in the Company’s consolidated balance sheets and are not material.

15. Share Plans

The Company adopted an equity incentive plan (Plan) on February 10, 2010 in connection with its initial public offering. The Plan, as amended, allows for granting of up to 9.1 million share-based awards to executives, directors and employees. Awards available for grant under the Plan include stock options, stock appreciation rights, restricted stock, other share-based awards and performance-based compensation awards. Total share-based compensation expense related to the Plan, net of estimated forfeitures, was $10,205, $9,493 and $8,241 for the years ended December 31, 2017, 2016 and 2015, respectively, which is recorded in operating expenses in the consolidated statements of comprehensive income.

Stock Options - Stock options granted in 2017 have an exercise price between $40.12 per share and $48.98 per share; stock options granted in 2016 have an exercise price between $33.23 per share and $35.37 per share, and the stock options granted in 2015 have an exercise price between $28.36 per share and $49.70 per share. Stock options vest in equal installments over four years, subject to the grantee’s continued employment or service and expire ten years after the date of grant.

Stock option exercises can be net-share settled such that the Company withholds shares with value equivalent to the exercise price of the stock option awards plus the employees’ minimum statutory obligation for the applicable income and other employment taxes. Total shares withheld were 9,033, 473,743 and 272,296 in 2017, 2016 and 2015, respectively, and were based on the value of the stock on the exercise dates. The net-share settlement has the effect of share repurchases by the Company as they reduce the number of shares that would have otherwise been issued.

Employees can also utilize a cashless for cash exercise of stock options, such that all exercised shares will be sold in the market immediately. Cash equivalent to the exercise price of the awards plus the employees’ minimum statutory tax obligations is remitted to the Company, with the remaining cash being transferred to the employee. Total proceeds from the cashless for cash exercise of stock options were $6,951 and $1,623 in 2017 and 2016, respectively, and are reflected as a financing activity in the consolidated statement of cash flows.

Total payments made by the Company for the employees’ tax obligations to the taxing authorities were $4,301, $13,056 and $9,768 in 2017, 2016 and 2015, respectively, and are reflected as a financing activity within the consolidated statements of cash flows.

65

The grant-date fair value of each option grant is estimated using the Black-Scholes-Merton option pricing model. The fair value is then amortized on a straight-line basis over the requisite service period of the awards, which is generally the vesting period. Use of a valuation model requires management to make certain assumptions with respect to selected model inputs. Expected volatility is calculated based on an analysis of historic and implied volatility measures for a set of peer companies. The average expected life is based on the contractual term of the option using the simplified method. The risk-free interest rate is based on U.S. Treasury zero-coupon issues with a remaining term equal to the expected life assumed at the date of grant. The compensation expense recognized is net of estimated forfeitures. Forfeitures are estimated based on actual share option forfeiture history. The weighted-average assumptions used in the Black-Scholes-Merton option pricing model for 2017, 2016 and 2015 are as follows:

	2017			2016			2015
Weighted average grant date fair value	$	16.84		$	13.77		$	19.07
Assumptions:
Expected stock price volatility		40	%		41	%		41	%
Risk free interest rate		1.92	%		1.31	%		1.72	%
Expected annual dividend per share	$	-		$	-		$	-
Expected life of options (years)		6.25			6.25			6.25

The Company periodically evaluates its forfeiture rates and updates the rates it uses in the determination of its share-based compensation expense. The impact of the change to the forfeiture rates on shares-based compensation expense was not material for the years ended December 31, 2017, 2016 and 2015.

A summary of the Company’s stock option activity and related information for the years ended December 31, 2017, 2016 and 2015 is as follows:

	Number of Options			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (in years)		Aggregate Intrinsic Value ($ in thousands)
Outstanding as of December 31, 2014		2,542,139		$	9.94		8.5	$	96,518

Granted		346,421			40.13
Exercised		(287,375	)		10.58
Forfeited		(69,880	)		41.12
Outstanding as of December 31, 2017		1,472,130			33.11		7.3	$	25,281
Exercisable as of December 31, 2017		720,730			26.76		6.1	$	17,239

As of December 31, 2017, there was $8,552 of total unrecognized compensation cost, net of expected forfeitures, related to unvested options. The cost is expected to be recognized over the remaining service period, having a weighted-average period of 2.5 years. Total share-based compensation cost related to the stock options for 2017, 2016 and 2015 was $4,503, $4,366 and $4,198, respectively, which is recorded in operating expenses in the consolidated statements of comprehensive income.

Restricted Stock – Restricted stock awards vest in equal installments over three years, subject to the grantee’s continued employment or service. Certain restricted stock awards also include performance shares, which were awarded in the years 2014 through 2017. The number of performance shares that can be earned are contingent upon Company performance measures over a three-year period. Performance measures are based on a weighting of revenue growth and EBITDA margin, from which grantees may earn from 0% to 200% of their target performance share award. The performance period for the 2015 awards covers the years 2015 through 2017, the performance period for the 2016 awards covers the years 2016 through 2018, and the performance period for the 2017 awards covers the years 2017 through 2019. The Company estimates the number of performance shares that will vest based on projected financial performance. The fair market value of the restricted awards at the time of the grant is amortized to expense over the period of vesting. The fair value of restricted awards is determined based on the market value of the Company's shares on the grant date. The compensation expense recognized for restricted share awards is net of estimated forfeitures.

66

Restricted stock vesting is net-share settled such that, upon vesting, the Company withholds shares with value equivalent to the employees’ minimum statutory obligation for the applicable income and other employment taxes, and then pays the cash to the taxing authorities on behalf of the employees. In effect, the Company repurchases these shares and classifies as treasury stock. Total shares withheld were 39,500, 28,593 and 65,763 in 2017, 2016 and 2015, respectively, and were based on the value of the stock on the vesting dates. Total payments made by the Company for the employees’ tax obligations to the taxing authorities were $1,591, $952 and $3,233 in 2017, 2016 and 2015, respectively, and are reflected as a financing activity within the consolidated statements of cash flows.

A summary of the Company's restricted stock activity for the years ended December 31, 2017, 2016 and 2015 is as follows:

	Shares			Weighted- Average Grant- Date Fair Value
Non-vested as of December 31, 2014		267,284		$	38.72

Forfeited		(47,100	)		42.48
Non-vested as of December 31, 2017		392,276			37.77

As of December 31, 2017, there was $7,702 of unrecognized compensation cost, net of expected forfeitures, related to non-vested restricted stock awards. That cost is expected to be recognized over the remaining service period, having a weighted-average period of 1.7 years. Total share-based compensation cost related to the restricted stock for 2017, 2016 and 2015 was $5,702, $5,127 and $4,043, respectively, which is recorded in operating expenses in the consolidated statements of comprehensive income.

During 2017, 2016 and 2015, 34,095, 19,326 and 16,260 shares, respectively, of stock were granted to certain members of the Company’s Board of Directors as a component of their compensation for their service on the Board, of which 22,762, 19,326 and 16,260 shares, respectively, were fully vested. Total share-based compensation cost for these share grants in 2017, 2016 and 2015 was $1,133, $670 and $615, respectively, which is recorded in operating expenses in the consolidated statements of comprehensive income.

16. Commitments and Contingencies

The Company leases certain manufacturing and office facilities, machinery and computer equipment, automobiles and warehouse space under operating leases. The approximate aggregate minimum rental commitments at December 31, 2017, are as follows:

2018	$	9,497
2019		7,786
2020		7,496
2021		6,647
2022		6,633

Total	$	43,924

67

Total rent expense for the years ended December 31, 2017, 2016 and 2015, was approximately $10,845, $9,146, and $4,796, respectively.

The Company has an arrangement with a finance company to provide floor plan financing for certain dealers. The Company receives payment from the finance company after shipment of product to the dealer. The Company participates in the cost of dealer financing up to certain limits and has agreed to repurchase products repossessed by the finance company, but does not indemnify the finance company for any credit losses they incur. The amount financed by dealers which remained outstanding under this arrangement at December 31, 2017 and 2016 was approximately $36,500 and $33,900, respectively.

In the normal course of business, the Company is named as a defendant in various lawsuits in which claims are asserted against the Company. In the opinion of management, the liabilities, if any, which may result from such lawsuits are not expected to have a material adverse effect on the financial position, results of operations, or cash flows of the Company.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

There were no changes in, or disagreements with, accountants reportable herein.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed by us in reports we file or submit under the Securities Exchange Act of 1934 (Exchange Act), is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure.

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, has conducted an evaluation of the design and operation of our disclosure controls and procedures as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act as of the end of the period covered by this report on Form 10-K. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective in providing reasonable assurance that the information required to be disclosed in this report on Form 10-K has been recorded, processed, summarized and reported as of the end of the period covered by this report on Form 10-K.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control over financial reporting is designed under the supervision of our Chief Executive Officer and Chief Financial Officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the consolidated financial statements in accordance with U.S. GAAP.

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 the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of the financial statements in accordance with U.S. GAAP, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the Company’s financial statements.

There are inherent limitations to the effectiveness of any internal control over financial reporting, including the possibility of human error or the circumvention or overriding of the controls. Accordingly, even an effective internal control over financial reporting can provide only reasonable assurance of achieving its objective. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate, because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, our management conducted an assessment of the effectiveness of internal control over financial reporting as of December 31, 2017 based on the criteria established in the 2013 Internal Control – Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, our management has concluded that our internal control over financial reporting was effective as of December 31, 2017.

69

In October 2017 and January 2018, two subsidiaries implemented the Company's global enterprise resource planning (ERP) systems. In connection with those ERP system implementations, we are updating our internal controls over financial reporting for those subsidiaries as necessary, to accommodate modifications to their business processes and accounting procedures. Additional implementations are expected to occur at our remaining locations over a multi-year period.

Deloitte & Touche LLP, the Company’s independent registered public accounting firm, issued an attestation report on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2017, which is included herein.

Changes in Internal Control Over Financial Reporting

Other than the assessment of controls for the ERP implementation noted above, there have been no changes in our internal control over financial reporting that occurred during the year ended December 31, 2017 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Significant Accounting Policies [Text Block]

2. Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its subsidiaries

that are consolidated in conformity with U.S. GAAP. All intercompany amounts and transactions have been eliminated in consolidation.

Cash

and Cash

Equivalents

The Company considers all highly liquid investments purchased with an original maturity of

three

months or less to be cash equivalents.

Concentration of Credit Risk

The Company maintains the majority of its

domestic cash in

one

commercial bank in multiple operating and investment accounts. Balances on deposit are insured by the Federal Deposit Insurance Corporation (FDIC) up to specified limits. Balances in excess of FDIC limits are uninsured.

One

customer accounted for

approximately

7%

and

9%

of accounts receivable at

December 31, 2017

and

2016,

respectively.

No

one

customer accounted for greater than

6%,

7%

and

7%,

of net sales during the years ended

December 31, 2017,

2016,

or

2015,

respectively.

Accounts Receivable

Receivables are recorded at their face value amount less an allowance for doubtful accounts. The Company estimates and records an allowance for doubtful accounts based on specific identification and historical experience. The Company writes off uncollectible accounts against the allowance for doubtful accounts after all collection efforts have been exhausted. Sales are generally made on an unsecured basis.

Inventories

Inventories are stated at the lower of cost or

market, with cost determined generally using the

first

-in,

first

-out method.

Property and Equipment

Property and equipment are recorded at cost and are being depreciated using the straight-line method over the estimated useful lives of the assets, which are summarized below (in years). Costs of leasehold improvements are amortized over the lesser of the term of the lease (including renewal option periods) or the estimated useful lives of the improvements.

Land improvements	8	–	20
Buildings and improvements	10	–	40
Machinery and equipment	3	–	15
Dies and tools	3	–	10
Vehicles	3	–	6
Office equipment and systems	3	–	15
Leasehold improvements	2	–	20

Total depreciation expense

was

$23,127,

$21,465,

and

$16,742

for the years ended

December 31, 2017,

2016,

and

2015,

respectively.

Goodwill and Other Indefinite-Lived Intangible Assets

Goodwill represents the excess of the purchase price over fair value of identifiable net assets acquired from business acquisitions. Goodwill is

not

amortized, but is reviewed for impairment on an annual basis and between annual tests

if indicators of impairment are present. The Company evaluates goodwill for impairment annually as of

October 31

or more frequently when an event occurs or circumstances change that indicates the carrying value

may

not

be recoverable. The Company has the option to assess goodwill for impairment by performing either a qualitative assessment or quantitative test. The qualitative assessment determines whether it is more likely than

not

that the fair value of a reporting unit is less than its carrying amount. If the Company determines that it is

not

more likely than

not

that the fair value of a reporting unit is less than its carrying amount, then the quantitative test is

not

required to be performed. If the Company determines that it is more likely than

not

that the fair value of a reporting unit is less than its carrying amount, the Company is required to perform the quantitative test. In the quantitative test, the calculated fair value of the reporting unit is compared to its book value including goodwill. If the fair value of the reporting unit is in excess of its book value, the related goodwill is

not

impaired. If the fair value of the reporting unit is less than its book value, an impairment loss is recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit.

Other indefinite-lived intangible assets consist of certain tradenames.

The Company tests the carrying value of these tradenames annually as of

October 31

or more frequently when an event occurs or circumstances change that indicates the carrying value

may

not

be recoverable by comparing the assets’ fair value to its carrying value. Fair value is measured using a relief-from-royalty approach, which assumes the fair value of the tradename is the discounted cash flows of the amount that would be paid had the Company

not

owned the tradename and instead licensed the tradename from another company.

The Company performed the required annual impairment tests for goodwill and other indefinite-lived intangible assets for the fiscal years

201

7,

2016

and

2015,

and found

no

impairment following the

2017

and

2016

tests. There were

no

reporting units with a carrying value at-risk of exceeding fair value as of the

October 31, 2017

impairment test date.

After performing the impairment tests for fiscal year

2015,

t

he Company determined that the fair value of the Ottomotores reporting unit was less than its carrying value, resulting in a non-cash goodwill impairment charge in the

fourth

quarter of

2015

of

$4,611

to write-down the balance of the Ottomotores goodwill. The decrease in fair value of the Ottomotores reporting unit was due to several factors in the

second

half of

2015:

the continued challenges of the Latin American economies, devaluation of the Peso against the U.S. Dollar, the slow development of Mexican energy reform as a result of decreasing oil prices; combining to cause

2015

results to fall short of prior expectations and future forecasts to decrease. The fair value was determined using a discounted cash flow analysis, which utilized key financial assumptions including the sales growth factors discussed above, a

3%

terminal growth rate and a

15.7%

discount rate.

In the

fourth

quarter of

2015,

the Company

’s Board of Directors approved a plan to strategically transition and consolidate certain of the Company’s brands acquired in acquisitions to the Generac® tradename. This brand strategy change resulted in a reclassification to a

two

year remaining useful life for the impacted tradenames, causing the fair value to be less than the carrying value using the relief-from-royalty approach in a discounted cash flow analysis. As such, a

$36,076

non-cash impairment charge was recorded to write-down the impacted tradenames to net realizable value.

Other than the impairment charges discussed above, the Company found

no

other impairment when performing the required annual

impairment tests for goodwill and other indefinite-lived intangible assets for fiscal year

2015.

There can be

no

assurance that future impairment tests will

not

result in a charge to earnings.

Impairment of

Long-Lived Assets

The Company periodically evaluates the carrying value of long-lived asset

s (excluding goodwill and indefinite-lived tradenames). Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount

may

not

be recoverable. If the sum of the expected future undiscounted cash flows is less than the carrying amount of an asset, a loss is recognized for the difference between the fair value and carrying value of the asset.

Debt Issuance Costs

Debt discounts and d

irect costs incurred in connection with the issuance of long-term debt are deferred and recorded as a reduction of outstanding debt and amortized to interest expense using the effective interest method over the terms of the related credit agreements. $

3,516,

$3,939,

and

$5,429

of deferred financing costs and original issue discount were amortized to interest expense during fiscal years

2017,

2016

and

2015,

respectively. Excluding the impact of any future long-term debt issuances or prepayments, estimated amortization to interest expense for the next

five

years is as follows:

2018

-

$4,798;

2019

-

$4,982;

2020

-

$4,936;

2021

-

$4,931;

2022

-

$5,099.

Income Taxes

The Company is

a C Corporation and therefore accounts for income taxes pursuant to the liability method. Accordingly, the current or deferred tax consequences of a transaction are measured by applying the provision of enacted tax laws to determine the amount of taxes payable currently or in future years. Deferred income taxes are provided for temporary differences between the income tax bases of assets and liabilities and their carrying amounts for financial reporting purposes. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than

not

that some portion or all of the deferred tax assets will

not

be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the years in which those temporary differences become deductible. The Company considers taxable income in prior carryback years, the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies, as appropriate, in making this assessment.

Revenue Recognition

Sales, net of estimated returns and allowances, are recognized upon shipment of product to the customer, which is generally when title passes, the Company has

no

further obligations, and the customer is required to pay subject to agreed upon payment terms. The Company, at the request of certain customers, will warehouse inventory billed to the customer but

not

delivered. Unless all revenue recognition criteria have been met, the Company does

not

recognize revenue on these transactions until the customers take possession of the product. In these cases, the funds collected on product warehoused for these customers are recorded as a customer advance until the customer takes possession of the product and the Company’s obligation to deliver the goods is completed. Customer advances are included in accrued liabilities in the consolidated balance sheets.

The Company provides for certain estimated sales

programs, discounts and incentive expenses which are recognized as a reduction of sales.

Shipping and Handling Costs

Shipping and handling costs billed to customers are included in net sales, and the related costs are included in cost of goods sold in the consolidated statements of comprehensive income.

Advertising and Co-Op Advertising

Expenditures for advertising, included in selling and service expenses in the consolidated statements of comprehensive income, are expensed as incurred. Total

expenditures for advertising were

$45,926,

$45,488,

and

$39,258

for the years ended

December 31, 2017,

2016,

and

2015,

respectively.

Research and Development

The Company expenses research and development costs as incurred. Total expenditures incurred for research and development

were

$42,925,

$37,229,

and

$32,922

for the years ended

December 31, 2017,

2016

and

2015,

respectively.

Foreign Currency Translation and Transactions

Balance sheet amounts for non-U.S. Dollar functional currency businesses

are translated into U.S. Dollars at the rates of exchange in effect at the end of the fiscal year. Income and expenses incurred in a foreign currency are translated at the average rates of exchange in effect during the year. The related translation adjustments are made directly to accumulated other comprehensive loss, a component of stockholders’ equity, in the consolidated balance sheets. Gains and losses from foreign currency transactions are recognized as incurred in the consolidated statements of comprehensive income.

Fair Value of Financial Instruments

ASC

820

-

10

,

Fair Value Measurement

,

defines fair value, establishes a consistent framework for measuring fair value, and expands disclosure for each major asset and liability category measured at fair value on either a recurring basis or nonrecurring basis. ASC

820

-

10

clarifies that fair value is an exit price, representing the amount that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the pronouncement establishes a

three

-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: (Level

1

) observable inputs such as quoted prices in active markets; (Level

2

) inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and (Level

3

) unobservable inputs in which there is little or

no

market data, which require the reporting entity to develop its own assumptions.

The Company believes the carrying amount of its financial instruments (cash and cash equivalents, accounts receivable, accounts

payable, accrued liabilities, short-term borrowings and ABL facility borrowings), excluding Term Loan borrowings, approximates the fair value of these instruments based upon their short-term nature. The fair value of Term Loan borrowings, which have an aggregate carrying value of

$902,959,

was approximately

$903,500

(Level

2

) at

December 31, 2017,

as calculated based on independent valuations whose inputs and significant value drivers are observable.

For the fair value of the assets and liabilities measured on a recurring basis,

refer to the fair value table in Note

4,

“Derivative Instruments and Hedging Activities,” to the consolidated financial statements. The fair value of all derivative contracts is classified as Level

2.

The valuation techniques used to measure the fair value of derivative contracts, all of which have counterparties with high credit ratings, were based on quoted market prices or model driven valuations using significant inputs derived from or corroborated by observable market data. The fair value of derivative contracts considers the Company’s credit risk in accordance with ASC

820

-

10.

Use of Estimates

The preparation of the consolidated financial statements in conformity with

U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Derivative Instruments and Hedging Activities

The Company records

all derivatives in accordance with ASC

815,

Derivatives and Hedging

, which requires derivative instruments be reported on the consolidated balance sheets at fair value and establishes criteria for designation and effectiveness of hedging relationships. The Company is exposed to market risk such as changes in commodity prices, foreign currencies and interest rates. The Company does

not

hold or issue derivative financial instruments for trading purposes.

Share-Based Compensation

Share-based compensation expense, including stock options and restricted stock awards, is generally recognized on a straight-line basis over the vesting period based on the fair value of awards which are expected to vest. The fair value of all share-based awards is estimated on the date of grant.

Revenue from Contracts with Customers

. This guidance is the culmination of the FASB’s joint project with the International Accounting Standards Board to clarify the principles for recognizing revenue. The core principal of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance provides a

five

-step process that entities should follow in order to achieve that core principal. ASU

The guidance can be applied either on a full retrospective basis or on a modified retrospective basis in which the cumulative effect of initially applying the standard is recognized at the date of initial application. The Company has completed its assessment of the impacts the standard will have on its financial statements, and determined that the adoption does

not

have a material impact. In all material respects, the Company has identified a similar amount of performance obligations under the new guidance as compared with deliverables previously identified. As a result, the timing of revenue recognition will generally remain the same. The Company adopted the standard

Leases

. This guidance is being issued to increase transparency and comparability among organizations by requiring the recognition of lease assets and lease liabilities on the balance sheet and by disclosing key information about leasing arrangements. The guidance should be applied using a modified retrospective approach and is effective for the Company in

2019,

with early adoption permitted. The Company is currently assessing the impact the adoption of this guidance will have on the Company’s results of operations and financial position.

Intangibles – Goodwill and Other: Simplifying the Test for Goodwill Impairment

. This guidance was issued to simplify the subsequent measurement of goodwill by eliminating Step

of the goodwill impairment test. Under the new guidance, the recognition of a goodwill impairment charge is calculated based on the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should

not

exceed the total amount of goodwill allocated to that reporting unit. This guidance should be applied on a prospective basis and is effective for the Company in

2020.

Targeted Improvements to Accounting for Hedging Activities

. This guidance was issued 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, and to make certain targeted improvements to simplify the application of the hedge accounting guidance. For existing hedges, this guidance should be applied using a cumulative effect adjustment, while the presentation and disclosure guidance should be adopted on a prospective basis.

Compensation – Stock Compensation: Improvements to Employee Share-Based Payment Accounting

. The primary impact of adoption is the prospective recognition of excess tax benefits or deficiencies within the provision for income taxes on the consolidated statement of comprehensive income rather than within additional paid-in capital on the consolidated balance sheet. Further, the Company has elected to continue to estimate forfeitures expected to occur to determine the amount of stock compensation expense recognized each period. The Company also elected to apply the presentation requirements for cash flows related to excess tax benefits or deficiencies prospectively. The presentation requirements for cash flows related to employee taxes paid in exchange for withheld shares had

no

impact to any period presented on the consolidated statements of cash flows as such cash flows have historically been presented as a financing activity. There were

no

cumulative effect adjustments made to equity as of the beginning of the fiscal period, as those provisions of ASU

impact to the Company.

There are several other new accounting pronouncements issued by the FASB. Each of these pronouncements, as applicable, has been or will be adopted by the Company. Management does

3. Acquisitions

Acquisition of Pramac

On

March 1, 2016,

the Company acquired a

65%

ownership interest in Pramac for a purchase price, net of cash acquired, of

$60,

250.

Headquartered in Siena, Italy, Pramac is a leading global manufacturer of stationary, mobile and portable generators primarily sold under the Pramac® brand. Pramac products are sold in over

150

countries through a broad distribution network. The acquisition purchase price was funded solely through cash on hand.

The

35%

noncontrolling interest in Pramac had an acquisition date fair value of

$34,253,

and was recorded as a redeemable noncontrolling interest in the consolidated balance sheet, as t

he noncontrolling interest holder has within its control the right to require the Company to redeem its interest in Pramac. The noncontrolling interest holder has a put option to sell their interests to the Company any time within

five

years from the date of acquisition. The put option price is either (i) a fixed amount if voluntarily exercised within the

first

two

years after the acquisition, or (ii) based on a multiple of earnings, subject to the terms of the acquisition. Additionally, the Company holds a call option that it

may

redeem commencing

five

years from the date of acquisition, or earlier upon the occurrence of certain circumstances. The call option price is based on a multiple of earnings that is subject to the terms of the acquisition. Both the put and call option only provide for the complete transfer of the noncontrolling interest, with

no

partial transfers of interest permitted.

The redeemable noncontrolling interest is recorded at the greater of the initial fair value, increased or decreased for the noncontrolling interests

’ share of comprehensive net income (loss), or the estimated redemption value, with any adjustment to the redemption value impacting retained earnings, but

not

net income. However, the redemption value adjustments are reflected in the earnings per share calculation, as detailed in Note

12,

“Earnings Per Share,” to the consolidated financial statements. The following table presents the changes in the redeemable noncontrolling interest:

( 1 ) Represents the additional noncontrolling interest of Pramac resulting from a common control transaction between the Generac Mobile Products S.r.l. and Pramac UK Lim ited legal entities.

The Company

finalized the Pramac purchase price allocation during the

first

quarter of

2017,

based upon its estimates of the fair value of the acquired assets and assumed liabilities. The final purchase price allocation as of the balance sheet date was as follows:

	March 1, 201 6

oses. The accompanying consolidated financial statements include the results of Pramac from the date of acquisition through

December 31, 2017.

Acquisition of CHP

On

August 1, 2015,

the Company acquired CHP for a purchase price, net of cash acquired, of

$74,570.

Headquartered in Vergennes, Vermont, CHP is a leading manufacturer of high-quality, innovative, professional-grade engine powered equipment used in a wide variety of property maintenance applications, with sales primarily in North America. The acquisition purchase price was funded solely through cash on hand.

The Company

finalized the CHP purchase price allocation during the

fourth

quarter of

2015

based upon its estimates of the fair value of the acquired assets and assumed liabilities. As a result, the Company recorded approximately

$75,174

of intangible assets, including approximately

$36,284

of goodwill, as of the acquisition date. The goodwill ascribed to this acquisition is

not

deductible for tax purposes. In addition, the Company assumed

$12,000

of debt along with this acquisition. The accompanying consolidated financial statements include the results of CHP from the date of acquisition through

December 31, 2017.

Pro Forma Information

The following unaudited pro forma information of the Company gives effect to these acquisitions as though the transactions

had occurred on

January 1, 2015.

Consolidated net sales on a pro forma basis for the years ended

December 31, 2016

and

2015

were

$1,473,799

and

$1,566,459,

respectively. The pro forma impact of these acquisitions on net income and earnings per share for both the years ended

December 31, 2016

and

2015

is

not

significant due to amortization related to acquired intangible assets and the fair value step-up of inventory in purchase accounting. This unaudited pro forma information is presented for informational purposes only and is

Derivative Instruments and Hedging Activities Disclosure [Text Block]

4. Derivative Instruments and Hedging Activities

Commodities

The

Company is exposed to price fluctuations in commodities it uses as raw materials; primarily steel, copper and aluminum; and periodically utilizes commodity derivatives to mitigate the impact of these potential price fluctuations on its financial results and its economic well-being. These derivatives typically have maturities of less than

eighteen

months. At both

December 31, 2017

and

2016,

the Company had

one

commodity contract outstanding, covering the purchases of copper.

Because these contracts do

not

qualify for hedge accounting,

the related gains and losses are recorded in cost of goods sold in the Company’s consolidated statements of comprehensive income. Net pre-tax gains (losses) recognized were

$377,

$739

and $(

1,909

) for the years ended

December 31, 2017,

2016,

and

2015,

respectively.

Foreign Currencies

The Company is exposed to foreign currency exchange risk as a result of transactions

denominated in currencies other than the U.S. Dollar. The Company periodically utilizes foreign currency forward purchase and sales contracts to manage the volatility associated with certain foreign currency purchases and sales in the normal course of business. Contracts typically have maturities of

twelve

months or less. As of

December 31, 2017

and

2016,

the Company had

twenty-eight

and

thirty-eight

foreign currency contracts outstanding, respectively.

Because these contracts do

not

qualify for hedge accounting,

the related gains and losses are recorded in other, net in the Company’s consolidated statements of comprehensive income. Net pre-tax gains (losses) recognized for the years ended

December 31, 2017,

October 2013,

the Company entered into

two

interest rate swap agreements; in

May 2014,

the Company entered into

one

interest rate swap agreement; and in

2017,

the Company entered into

twenty

additional interest rate swap agreements. The Company formally documented all relationships between interest rate hedging instruments and the related hedged items, as well as its risk-management objectives and strategies for undertaking these hedge transactions. These interest rate swap agreements qualify as cash flow hedges, and accordingly, the effective portions of the gains or losses are reported as a component of accumulated other comprehensive loss (AOCL)

 

in the consolidated balance sheets. 

The amount of gains (losses) recognized for the years ended

December 31, 2017,

2016

and

2015

were

$3,712,

$535

and $(

Segment Reporting Disclosure [Text Block]

6. Segment Reporting

The Company has

two

reportable segments for financial reporting purposes – Domestic and International. The Domestic segment includes the legacy Generac business and the impact of acquisitions that are based in the United States, all of which have revenues that are substantially derived from the U.S. and Canada. The International segment includes the Ottomotores, Tower Light, Pramac and Motortech acquisitions, all of which have revenues that are substantially derived from outside of the U.S and Canada. Both reportable segments design and manufacture a wide range of power generation equipment and other engine powered products. The Company has multiple operating segments, which it aggregates into the

two

reportable segments, based on materially similar economic characteristics, products, production processes, classes of customers and distribution methods. All segment information has been retrospectively applied to all periods presented to reflect the current reportable segment structure.

	Net Sale s

Tota l	$	1,672,445	$	1,444,453	$	1,317,299

The Company's product offerings consist primarily of power

generation equipment and other engine powered products geared for varying end customer uses. Residential products and commercial & industrial products are each a similar class of products based on similar power output and end customer. The breakout of net sales by product class between residential, commercial & industrial, and other products is as follows:

	Net Sale s
	Year Ended December 31 ,
Product Classe s	201 7		201 6		201 5
Residential product s	$	870,410	$	772,436	$	673,764

Tota l	$	1,672,445	$	1,444,453	$	1,317,299

Management evaluates the performance of its segments based primarily on Adjusted EBITDA

before noncontrolling interests, which is reconciled to Income before provision for income taxes below. The computation of Adjusted EBITDA is based on the definition that is contained in the Company’s credit agreements.

9. Product Warranty Obligations

The Company records a liability for product warranty obligations at the time of sale to a customer based upon historical warranty experience. The Company also records a liability for specific warranty matters when they become known and are reasonably estimable.

Additionally, the Company sells extended warranty coverage for certain products. The sales of extended warranties are recorded as deferred revenue, which is recognized over the life of the contracts following the standard warranty period.

The following is a tabular reconciliation of the product warranty liability,

excluding the deferred revenue related to our extended warranty coverage:

The

Company’s credit agreements originally provided for a

$1,200,000

term loan B credit facility (Term Loan) and currently include a

$300,000

uncommitted incremental term loan facility. In

November 2016,

the Company amended its Term Loan to extend the maturity date from

May 31, 2020

to

May 31, 2023.

The Term Loan is guaranteed by all of the Company’s wholly-owned domestic restricted subsidiaries, and is secured by associated collateral agreements which pledge a

first

priority lien on virtually all of the Company’s assets, including fixed assets and intangibles, other than all cash, trade accounts receivable, inventory, and other current assets and proceeds thereof, which are secured by a

second

priority lien. The Term Loan initially bore interest at rates based upon either a base rate plus an applicable margin of

1.75%

or adjusted LIBOR rate plus an applicable margin of

2.75%,

subject to a LIBOR floor of

0.75%.

Beginning in the

second

quarter of

2014,

and measured each quarterly period thereafter, the applicable margin related to base rate loans was reduced to

1.50%

and the applicable margin related to LIBOR rate loans is reduced to

2.50%,

in each case, if the Company’s net debt leverage ratio, as defined in the Term Loan, falls below

3.00

to

1.00

for that measurement period.

Because the Company

’s net debt leverage ratio was above

3.00

to

1.00

on

July 1, 2015,

it realized a

25

basis point increase in borrowing costs in the

third

quarter of

2015.

As a result, the Company recorded a cumulative catch-up loss of

$2,381

in the

third

quarter of

2015,

which represented the additional cash interest expected to be paid while the net debt leverage ratio was expected to be above

3.00

to

1.00

using current forecasts at that time. The loss was recorded against original issue discount and deferred financing costs on long-term borrowings in the consolidated balance sheets and as a loss on change in contractual interest rate in the consolidated statement of comprehensive income.

As the Company

’s net debt leverage ratio continued to be above

3.00

to

1.00

on

July 1, 2016,

the Company recorded a cumulative catch-up loss of

$2,957

in the

third

quarter of

2016,

which represented the additional cash interest expected to be paid while the net debt leverage ratio was expected to be above

3.00

to

1.00

using current forecasts at that time. The loss was recorded against original issue discount and deferred financing costs on long-term borrowings in the consolidated balance sheets and as a loss on change in contractual interest rate in the consolidated statement of comprehensive income.

the Company amended its Term Loan, modifying the pricing of the facility by reducing the applicable margin rates to base rate plus a fixed applicable margin of

1.25%

or adjusted LIBOR rate plus a fixed applicable margin of

2.25%.

Further, the amendment removed the pricing grid that would reduce the applicable margin if a net debt leverage ratio of

3.00

to

1.00

was achieved. As a result, the Company does

not

anticipate any future catch-up gains or losses resulting from changes in contractual interest rates to be recorded in the statements of comprehensive income. The amended Term Loan pricing is still subject to the

December 2017,

the Company amended its Term Loan,

which further reduced the applicable margin rates to base rate plus a fixed applicable margin of

1.00%

2.00%.

Additionally, the amendment eliminated the Excess Cash Flow payment requirement for

2017,

As of

December 31, 2017,

the Company's secured leverage ratio was

2.50

to

1.00

times, and the Company was in compliance with all covenants of the Term Loan. There are

no

financial maintenance covenants on the Term Loan.

T

he Company’s credit agreements also originally provided for a

$150,000

senior secured ABL revolving credit facility (ABL Facility). The maturity date of the ABL Facility originally was

May 31, 2018.

Borrowings under the ABL Facility are guaranteed by all of the Company’s wholly-owned domestic restricted subsidiaries, and are secured by associated collateral agreements which pledge a

first

priority lien on all cash, trade accounts receivable, inventory, and other current assets and proceeds thereof, and a

second

priority lien on all other assets, including fixed assets and intangibles of the Company and certain domestic subsidiaries. ABL Facility borrowings initially bore interest at rates based upon either a base rate plus an applicable margin of

1.00%

or adjusted LIBOR rate plus an applicable margin of

2.00%,

in each case, subject to adjustments based upon average availability under the ABL Facility.

Additionally, the amendment relaxes certain restrictions on the Company’s ability to, among other things, (i) make additional investments and acquisitions (including foreign acquisitions), (ii) make restricted payments and (iii) incur additional secured and unsecured debt (including foreign subsidiary debt).

The Company

’s provision for income taxes consists of the following:

Provision for income taxe s	$	43,553		$	57,570		$	45,236

The Company files U.S federal, U.S. state and foreign jurisdiction tax returns that are subject to examination up to the expiration of the statute of limitations. We believe the tax positions taken on our returns would be sustained upon an exam, or where a position is uncertain, adequate reserves have been recorded.

 As of

December 31, 2017

the Company is

no

longer subject to income tax examinations for United States federal income taxes for the tax years prior to

2

014.

Due to the carryforward of net operating losses, and research and development credits, the Company's Wisconsin state income tax returns for tax years

2007

through

2016

remain open. In addition, the Company is subject to audit by various foreign taxing jurisdictions for the tax years

2012

through

2016.

The Company is currently under examination in multiple jurisdictions and is working to address all matters. While the Compa

ny does

not

believe any material taxes or penalties are due, there is a possibility that the ultimate tax outcome of an examination

may

result in differences from what was recorded. Such differences

may

affect the provision for income taxes in the period in which the determination is made, and could impact the Company’s financial results.

On

December 22, 2017,

the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act makes broad and complex changes to the U.S. tax code, including, but

not

limited to, reducing the U.S. federal corporate tax rate from

35%

 to

21%

, requiring companies to pay a

one

-time transition tax on certain unrepatriated earnings of foreign subsidiaries, eliminating certain deductions, introducing new tax regimes, changing how foreign earnings are subject to U.S. tax, and enhancing and extending through

2026

the option to claim accelerated depreciation deductions on qualified property.

The SEC staff issued SAB

118,

which provides guidance on accounting for the tax effects of the Tax Act. SAB

118

provides a measurement period that should

not

extend beyond

one

year from the Tax Act enactment date for companies to complete the accounting under ASC

740.

In accordance with SAB

118,

a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC

740

is complete. To the extent that a company

’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC

740

on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act.

The Company's accounting for the following elements of the Tax Act is incomplete. However, reasonable estimates of certain effects were able to be made and, therefore, provisional adjustments were recorded as follows:

Reduction of US federal corporate tax rate:

The Tax Act reduces the federal corporate tax rate to

21%

, effective

January 1, 2018.

For certain of the Company's deferred tax liabilities (DTLs), a provisional decrease of

$28,434

was recorded to reflect our DTLs at thelower corporate tax rate, with a corresponding net adjustment to deferred income tax benefit of

$28,434

for the year ended

December 31, 2017.

While a reasonable estimate of the impact of the reduction in the corporate tax rate was made, it

may

be affected by other analyses related to the Tax Act, including, but

not

limited to, the calculation of deemed repatriation of deferred foreign income and the state tax effect of adjustments made to federal temporary differences.

Deemed Repatriation Transition Tax:

The Deemed Repatriation Transition Tax (Transition Tax) is a tax on previously untaxed accumulated and current earnings and profits (E&P) of certain of the Company

’s foreign subsidiaries. To determine the amount of the Transition Tax, the amount of post-

1986

E&P of relevant subsidiaries, as well as the amount of non-U.S. income taxes paid on such earnings must be determined, in addition to other factors. The Company made a reasonable estimate of the Transition Tax and has concluded the amount was

not

material.

Cost recovery:

While the Company has 

not

yet completed all of the computations necessary or completed an inventory of our

2017

expenditures that qualify for immediate expensing, a provisional benefit of

$700

 was recorded based on our current intent to fully expense all qualifying expenditures. This resulted in a decrease of approximately

$1,750

to current income tax payable and a corresponding increase in DTLs of approximately

$1,050

(after considering the effects of the reduction in income tax rates).

As the Company completes its analysis of the Tax Act; collects and prepares necessary data; and interprets any additional guidance issued by the U.S. Treasury Department, the IRS, and other standard-setting bodies; adjustments to the provisional amounts

may

be recorded.

Global intangible low taxed income (GILTI):

Because of the complexity of the new GILTI tax rules, the Company is continuing to evaluate this provision of the Tax Act and the application of ASC

740.

Under U.S. GAAP, the Company is allowed to make an accounting policy choice of either (

1

) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the “period cost method”) or (

2

) factoring such amounts into a company’s measurement of its deferred taxes (the “deferred method”). The selection of an accounting policy with respect to the new GILTI tax rules will depend, in part, on analyzing the Company's global income to determine whether it is expected to have future U.S. inclusions in taxable income related to GILTI and, if so, what the impact is expected to be. Because whether the Company expects to have future U.S. inclusions in taxable income related to GILTI depends

not

only on the current structure and estimated future results of global operations but also on the intent and ability to modify the structure and/or the business; the Company is not yet able to reasonably estimate the effect of this provision of the Tax Act. Therefore,

no

 adjustments related to potential GILTI tax have been made in the financial statements and

no

policy decision regarding whether to record deferred taxes on GILTI has been made.

Significant components of deferred tax assets and liabilities are as follows:

	December 31,
	201 7			201 6
Deferred tax assets:
Accrued expense s	$	15,138		$	22,758

Net deferred tax liabilities	$	(40,551	)	$	(13,941	)

As of

December 31,

201

7

and

2016,

deferred tax assets of

$3,238

and

$3,337,

and deferred tax liabilities of

$43,789

and

$17,278,

respectively, were reflected on the consolidated balance sheets.

One of the Company's subsidiaries, Generac Brazil,

has generated net operating losses for multiple years. The realizability of the deferred tax assets associated with these net operating losses is uncertain, therefore a valuation allowance has been recorded since Generac Brazil's acquisition on

December 8, 2012

and continued through

December 31, 2017.

In addition, the Company recorded a valuation allowance in the opening balance sheet and as of

December 31,

2017

and

2016

related to the Pramac acquisition. The valuation allowance represents a reserve for deferred tax assets, including loss carryforwards, of certain Pramac subsidiaries, for which utilization is uncertain.

At

December 31,

201

7,

the Company had state research and development tax credit carryforwards, and state manufacturing tax credit carryforwards of approximately

$13,089

and

$4,618,

respectively, which expire between

2018

and

2032.

A valuation allowance of

$1,171

has been established against deferred tax assets for these carryforwards.

Changes in the Company

’s gross liability for unrecognized tax benefits, excluding interest and penalties, were as follows:

	December 31,
	201 7			201 6
Unrecognized tax benefit, beginning of perio d	$	7,943		$	7,239
Increase in unrecognized tax benefit for positions take n in current perio d		251			704
Statute of limitation expirations		(1,072	)		-
Unrecognized tax benefit, end of perio d	$	7,122		$	7,943

The unrecognized tax

benefit as of 

December 

31,

2017

and

2016,

if recognized, would impact the effective tax rate.

As of 

December 

31,

2017,

2016

and

2015,

total accrued interest of approximately

$131,

 

$272

and

$174,

respectively, and accrued penalties of approximately 

$220,

$425

and

$363,

respectively, associated with net unrecognized tax benefits are included in the Company’s consolidated balance sheets. 

Interest and penalties are recorded as a component of income tax expense.

T

he Company does

not

expect a significant increase or decrease to the total amounts of unrecognized tax benefits related to continuing operations during the fiscal year ending

December 

31,

2018.

The Tax Act includes a mandatory

one

-time tax on accumulated earnings of foreign subsidiaries, and as a result, all previously

unremitted earnings for which

no

U.S. deferred tax liability had been accrued have now been subject to U.S. tax. Notwithstanding the U.S. taxation of these amounts, the Company intends to continue to invest these earnings, as well as the capital in these subsidiaries, indefinitely outside of the U.S. and do

not

expect to incur any significant, additional taxes related to such amounts.

A reconciliation

of the statutory tax rates and the effective tax rates for the years ended

December 31, 2017

,

2016

and

2015

are as follows:

	Year Ended December 31,
	201 7			201 6			201 5

( 1 ) With the adoption of ASU 2016 - 09 in the first quarter of 2017, excess tax benefits from equity awards are reflected within the provision for income taxes rather than within the consolidated balance sheet. For further information on the Company’s adoption of ASU 2016 - 09, refer to Note 2, “Significant Accounting Policies – New Accounting Pronouncements” to the consolidated financial statements.

Notes to Financial Statements

Pension and Other Postretirement Benefits Disclosure [Text Block]

14. Benefit Plans

Medical and Dental Plan

The Company maintains medical and dental benefit plans covering

its full-time domestic employees and their dependents. Certain plans are partially or fully self-funded under which participant claims are obligations of the plan. These plans are funded through employer and employee contributions at a level sufficient to pay for the benefits provided by the plan. The Company’s contributions to the plans were

$14,992,

$15,019,

and

$14,352

for the years ended

December 31, 2017,

2016,

and

2015,

respectively.

The Company

’s foreign subsidiaries participate in government sponsored medical benefit plans. In certain cases, the Company purchases supplemental medical coverage for certain employees at these foreign locations

. The expenses related to these plans are

not

material to the Company’s consolidated financial statements.

S

avings Plan

The Company maintains

 a defined-contribution

401

(k) savings plan for eligible domestic employees. Under the plan, employees

may

defer receipt of a portion of their eligible compensation. The Company amended the

401

(k) savings plans effective

January 1, 2009,

to add Company matching and non-elective contributions. The Company

may

contribute a matching contribution of

50%

of the

first

6%

of eligible compensation of employees. The Company

may

also contribute a non-elective contribution for eligible employees employed on

December 31, 2008.

Both Company matching contributions and non-elective contributions are subject to vesting. Forfeitures

may

be applied against plan expenses and company contributions. The Company recognized

$3,600,

$3,400

and

$3,000

of expense related to these plans in

2017,

2016

and

2015,

respectively.

Pension Plans

The Company has

frozen noncontributory salaried and hourly pension plans (Pension Plans) covering certain domestic employees.

The Pension Plans were frozen effective

December 31, 2008.

The benefits under the salaried plan are based upon years of service and the participants’ defined final average monthly compensation. The benefits under the hourly plan are based on a unit amount at the date of termination multiplied by the participant’s years of credited service. The Company’s funding policy for the Pension Plans is to contribute amounts at least equal to the minimum annual amount required by applicable regulations.

The Company uses a

December 31

measurement date for the Pension Plans.

The accumulated benefit obligation, reconciliation of the changes in projected benefit obligation, changes in plan assets and the funded status of the Pension Plans are as follows:

	Year Ended December 31,
	201 7			201 6

Amounts recognized in accumulated other comprehensive loss
Net a ctuarial loss, net of tax	$	(10,978	)	$	(11,040	)

The

actuarial loss for the Pension Plans that was amortized from AOCL into net periodic (benefit) cost during

2017

is

$883.

The amount in AOCL as of

December 31, 2017

that is expected to be recognized as a component of net periodic pension expense during the next fiscal year is

$802.

The

components of net periodic pension cost are as follows:

	Year E nded December 31,
	201 7			201 6			201 5
Interest cost	$	2,688		$	2,747		$	2,681

Amortization of net loss		883			941			1,228
Net periodic pension  cost	$	560		$	820		$	868

Weighted-average assumptions used to determine

the benefit obligations are as follows:

	December 31,
	201 7			201 6
Discount rate – salaried pension plan		3.60	%		4.14	%
Discount rate – hourly pension plan		3.62	%		4.16	%
Rate of compensation increase (1)		n/a			n/a

( 1 ) No compensation increase was assumed as the plans were frozen effective December 31, 2008.

Weighted-average assumptions used to

determine net periodic pension cost are as follows:

	Y ear E nded December 31,
	201 7			201 6			201 5
Discount rate		4.14	%		4.39	%		3.99	%

Rate of compensation increase (1)		n/a			n/a			n/a

( 1 ) No compensation increase was assumed as the plans were frozen effective December 31, 2008 .

To determine the long-term rate of return assumption for the plans' assets, the Company studies historical markets and preserves the long-term historical relationships between equities and fixed-income securities consistent with the widely accepted capital market principle that assets with higher volatility generate a greater return over the long run. The Company evaluates current market factors such as inflation and interest rates before it determines long-term capital market assumptions and reviews peer data and historical returns to check for reasonableness and

appropriateness.

Mutual Funds

– This category includes investments in mutual funds that encompass both equity and fixed income securities that are designed to provide a diverse portfolio. The plans' mutual funds are designed to track exchange indices, and invest in diverse industries. Some mutual funds are classified as regulated investment companies. Investment managers have the ability to shift investments from value to growth strategies, from small to large capitalization funds, and from U.S. to international investments. These investments are valued at the closing price reported on the active market on which the individual securities are traded. These investments are classified within Level

1

of the fair value hierarchy.

Other Investments

– This category includes investments in limited partnerships and are valued at estimated fair value, as determined with the assistance of each respective limited partnership, based on the net asset value of the investment as of the balance sheet date, which is subject to judgment, and therefore is classified within Level

3

of the fair value hierarchy.

The Company

’s target allocation for equity securities and real estate is generally between

65%

-

85%,

with the remainder allocated primarily to fixed income (bonds). The Company regularly reviews its actual asset allocation and periodically rebalances its investments to the targeted allocation when considered appropriate.

At a minimum, the Company expects to make

estimated contributions of

$319

to the Pension Plans in

2018.

The following benefit payments are expected to be paid from the Pension Plans:

201 8	$	2,445
201 9		2,502

20 21		2,760
202 2		2,932
2023 – 2027		16,989

Certain of the Company

’s foreign subsidiaries participate in local statutory defined benefit or other post-employment benefit plans. These plans provide benefits that are generally based on years of credited service and a percentage of the employee’s eligible compensation earned throughout the applicable service period. Liabilities recorded under these plans are included in accrued wages and employee benefits in the Company’s consolidated balance sheets and are

not

material.

15. Share Plans

The Company adopted an equity incentive plan

(Plan) on

February 10, 2010

in connection with its initial public offering. The Plan, as amended, allows for granting of up to

9.1

million share-based awards to executives, directors and employees. Awards available for grant under the Plan include stock options, stock appreciation rights, restricted stock, other share-based awards and performance-based compensation awards. Total share-based compensation expense related to the Plan, net of estimated forfeitures, was

$10,205,

$9,493

and

$8,241

for the years ended

December 31, 2017,

2016

and

2015,

respectively, which is recorded in operating expenses in the consolidated statements of comprehensive income.

Stock Options

- Stock options granted in

2017

have an exercise price between

$40.12

per share and

$48.98

per share; stock options granted in

2016

have an exercise price between

$33.23

per share and

$35.37

per share, and the stock options granted in

2015

have an exercise price between

$28.36

per share and

$49.70

per share. Stock options vest in equal installments over

four

years, subject to the grantee’s continued employment or service and expire

ten

years after the date of grant.

S

tock option exercises can be net-share settled such that the Company withholds shares with value equivalent to the exercise price of the stock option awards plus the employees’ minimum statutory obligation for the applicable income and other employment taxes. Total shares withheld were

9,033,

473,743

and

272,296

in

2017,

2016

and

2015,

respectively, and were based on the value of the stock on the exercise dates. The net-share settlement has the effect of share repurchases by the Company as they reduce the number of shares that would have otherwise been issued.

Employees can also utilize a cashless for cash exercise of stock options, such that all exercised shares will be sold in the market immediately. Cash equivalent to the exercise price of the awards plus the employees

’ minimum statutory tax obligations is remitted to the Company, with the remaining cash being transferred to the employee. Total proceeds from the cashless for cash exercise of stock options were

$6,951

and

$1,623

in

2017

and

2016,

respectively, and are reflected as a financing activity in the consolidated statement of cash flows.

Total payments made by the Company for the employees

’ tax obligations to the taxing authorities were

$4,301,

$13,056

and

$9,768

in

2017,

2016

and

2015,

respectively, and are reflected as a financing activity within the consolidated statements of cash flows.

The grant-date fair value of each option grant is estimated using the Black-Scholes-Merton option pricing model. The fair value is then amortized on a straight-line basis over the requisite service period of the awards, which is generally the vesting period. Use of a valuation model requires management to make certain assumptions with respect to selected model inputs.

Expected volatility is calculated based on an analysis of historic and implied volatility measures for a set of peer companies. The average expected life is based on the contractual term of the option using the simplified method. The risk-free interest rate is based on U.S. Treasury

zero

-coupon issues with a remaining term equal to the expected life assumed at the date of grant. The compensation expense recognized is net of estimated forfeitures. Forfeitures are estimated based on actual share option forfeiture history. The weighted-average assumptions used in the Black-Scholes-Merton option pricing model for

2017,

As of

December 31,

201

7,

there was

$8,552

of total unrecognized compensation cost, net of expected forfeitures, related to unvested options. The cost is expected to be recognized over the remaining service period, having a weighted-average period of

2.5

 years. Total share-based compensation cost related to the stock options for

2017,

2016

and

2015

was

$4,503,

$4,366

and

$4,198,

respectively, which is recorded in operating expenses in the consolidated statements of comprehensive income.

Restricted Stock

– Restricted stock awards vest in equal installments over

three

years, subject to the grantee’s continued employment or service. Certain restricted stock awards also include performance shares, which were awarded in the years

2014

through

2017.

The number of performance shares that can be earned are contingent upon Company performance measures over a

three

-year period. Performance measures are based on a weighting of revenue growth and EBITDA margin, from which grantees

may

earn from

0%

to

200%

of their target performance share award. The performance period for the

2015

awards covers the years

2015

through

2017,

the performance period for the

2016

awards covers the years

2016

through

2018,

and the performance period for the

2017

awards covers the years

2017

through

2019.

The Company estimates the number of performance shares that will vest based on projected financial performance. The fair market value of the restricted awards at the time of the grant is amortized to expense over the period of vesting. The fair value of restricted awards is determined based on the market value of the Company's shares on the grant date. The compensation expense recognized for restricted share awards is net of estimated forfeitures.

Restricted stock vesting is net-share settled such that

, upon vesting, the Company withholds shares with value equivalent to the employees’ minimum statutory obligation for the applicable income and other employment taxes, and then pays the cash to the taxing authorities on behalf of the employees. In effect, the Company repurchases these shares and classifies as treasury stock. Total shares withheld were

39,500,

28,593

and

65,763

in

2017,

2016

and

2015,

respectively, and were based on the value of the stock on the vesting dates. Total payments made by the Company for the employees’ tax obligations to the taxing authorities were

$1,591,

$952

and

$3,233

and

$16,742

for the years ended

December 31, 2017,

2016,

and

2015,

respectively.

Goodwill and Intangible Assets, Policy [Policy Text Block]

Goodwill and Other Indefinite-Lived Intangible Assets

Goodwill represents the excess of the purchase price over fair value of identifiable net assets acquired from business acquisitions. Goodwill is

not

amortized, but is reviewed for impairment on an annual basis and between annual tests

if indicators of impairment are present. The Company evaluates goodwill for impairment annually as of

October 31

or more frequently when an event occurs or circumstances change that indicates the carrying value

may

not

be recoverable. The Company has the option to assess goodwill for impairment by performing either a qualitative assessment or quantitative test. The qualitative assessment determines whether it is more likely than

not

that the fair value of a reporting unit is less than its carrying amount. If the Company determines that it is

not

more likely than

not

that the fair value of a reporting unit is less than its carrying amount, then the quantitative test is

not

required to be performed. If the Company determines that it is more likely than

not

that the fair value of a reporting unit is less than its carrying amount, the Company is required to perform the quantitative test. In the quantitative test, the calculated fair value of the reporting unit is compared to its book value including goodwill. If the fair value of the reporting unit is in excess of its book value, the related goodwill is

not

impaired. If the fair value of the reporting unit is less than its book value, an impairment loss is recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit.

Other indefinite-lived intangible assets consist of certain tradenames.

The Company tests the carrying value of these tradenames annually as of

October 31

or more frequently when an event occurs or circumstances change that indicates the carrying value

may

not

be recoverable by comparing the assets’ fair value to its carrying value. Fair value is measured using a relief-from-royalty approach, which assumes the fair value of the tradename is the discounted cash flows of the amount that would be paid had the Company

not

owned the tradename and instead licensed the tradename from another company.

The Company performed the required annual impairment tests for goodwill and other indefinite-lived intangible assets for the fiscal years

201

7,

2016

and

2015,

and found

no

impairment following the

2017

and

2016

tests. There were

no

reporting units with a carrying value at-risk of exceeding fair value as of the

October 31, 2017

impairment test date.

After performing the impairment tests for fiscal year

2015,

t

he Company determined that the fair value of the Ottomotores reporting unit was less than its carrying value, resulting in a non-cash goodwill impairment charge in the

fourth

quarter of

2015

of

$4,611

to write-down the balance of the Ottomotores goodwill. The decrease in fair value of the Ottomotores reporting unit was due to several factors in the

second

half of

2015:

the continued challenges of the Latin American economies, devaluation of the Peso against the U.S. Dollar, the slow development of Mexican energy reform as a result of decreasing oil prices; combining to cause

2015

results to fall short of prior expectations and future forecasts to decrease. The fair value was determined using a discounted cash flow analysis, which utilized key financial assumptions including the sales growth factors discussed above, a

3%

terminal growth rate and a

15.7%

discount rate.

In the

fourth

quarter of

2015,

the Company

’s Board of Directors approved a plan to strategically transition and consolidate certain of the Company’s brands acquired in acquisitions to the Generac® tradename. This brand strategy change resulted in a reclassification to a

two

year remaining useful life for the impacted tradenames, causing the fair value to be less than the carrying value using the relief-from-royalty approach in a discounted cash flow analysis. As such, a

$36,076

non-cash impairment charge was recorded to write-down the impacted tradenames to net realizable value.

Other than the impairment charges discussed above, the Company found

no

other impairment when performing the required annual

impairment tests for goodwill and other indefinite-lived intangible assets for fiscal year

2015.

There can be

no

assurance that future impairment tests will

not

result in a charge to earnings.

Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]

Impairment of

Long-Lived Assets

The Company periodically evaluates the carrying value of long-lived asset

s (excluding goodwill and indefinite-lived tradenames). Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount

may

not

be recoverable. If the sum of the expected future undiscounted cash flows is less than the carrying amount of an asset, a loss is recognized for the difference between the fair value and carrying value of the asset.

Debt, Policy [Policy Text Block]

Debt Issuance Costs

Debt discounts and d

irect costs incurred in connection with the issuance of long-term debt are deferred and recorded as a reduction of outstanding debt and amortized to interest expense using the effective interest method over the terms of the related credit agreements. $

3,516,

$3,939,

and

$5,429

of deferred financing costs and original issue discount were amortized to interest expense during fiscal years

2017,

2016

and

2015,

respectively. Excluding the impact of any future long-term debt issuances or prepayments, estimated amortization to interest expense for the next

five

years is as follows:

2018

-

$4,798;

2019

-

$4,982;

2020

$5,099.

Income Tax, Policy [Policy Text Block]

Income Taxes

The Company is

a C Corporation and therefore accounts for income taxes pursuant to the liability method. Accordingly, the current or deferred tax consequences of a transaction are measured by applying the provision of enacted tax laws to determine the amount of taxes payable currently or in future years. Deferred income taxes are provided for temporary differences between the income tax bases of assets and liabilities and their carrying amounts for financial reporting purposes. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than

not

that some portion or all of the deferred tax assets will

not

be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the years in which those temporary differences become deductible. The Company considers taxable income in prior carryback years, the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies, as appropriate, in making this assessment.

Revenue Recognition, Policy [Policy Text Block]

Revenue Recognition

Sales, net of estimated returns and allowances, are recognized upon shipment of product to the customer, which is generally when title passes, the Company has

no

further obligations, and the customer is required to pay subject to agreed upon payment terms. The Company, at the request of certain customers, will warehouse inventory billed to the customer but

not

delivered. Unless all revenue recognition criteria have been met, the Company does

not

recognize revenue on these transactions until the customers take possession of the product. In these cases, the funds collected on product warehoused for these customers are recorded as a customer advance until the customer takes possession of the product and the Company’s obligation to deliver the goods is completed. Customer advances are included in accrued liabilities in the consolidated balance sheets.

The Company provides for certain estimated sales

programs, discounts and incentive expenses which are recognized as a reduction of sales.

Shipping and Handling Cost, Policy [Policy Text Block]

Shipping and Handling Costs

Shipping and handling costs billed to customers are included in net sales, and the related costs are included in cost of goods sold in the consolidated statements of comprehensive income.

Advertising Costs, Policy [Policy Text Block]

Advertising and Co-Op Advertising

Expenditures for advertising, included in selling and service expenses in the consolidated statements of comprehensive income, are expensed as incurred. Total

expenditures for advertising were

$45,926,

$45,488,

and

$39,258

for the years ended

December 31, 2017,

2016,

The Company expenses research and development costs as incurred. Total expenditures incurred for research and development

were

$42,925,

$37,229,

and

$32,922

for the years ended

December 31, 2017,

2016

and

2015,

respectively.

Foreign Currency Transactions and Translations Policy [Policy Text Block]

Foreign Currency Translation and Transactions

Balance sheet amounts for non-U.S. Dollar functional currency businesses

are translated into U.S. Dollars at the rates of exchange in effect at the end of the fiscal year. Income and expenses incurred in a foreign currency are translated at the average rates of exchange in effect during the year. The related translation adjustments are made directly to accumulated other comprehensive loss, a component of stockholders’ equity, in the consolidated balance sheets. Gains and losses from foreign currency transactions are recognized as incurred in the consolidated statements of comprehensive income.

Fair Value of Financial Instruments, Policy [Policy Text Block]

Fair Value of Financial Instruments

,

Fair Value Measurement

,

defines fair value, establishes a consistent framework for measuring fair value, and expands disclosure for each major asset and liability category measured at fair value on either a recurring basis or nonrecurring basis. ASC

820

-

10

clarifies that fair value is an exit price, representing the amount that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the pronouncement establishes a

three

-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: (Level

1

) observable inputs such as quoted prices in active markets; (Level

2

) inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and (Level

3

) unobservable inputs in which there is little or

no

market data, which require the reporting entity to develop its own assumptions.

The Company believes the carrying amount of its financial instruments (cash and cash equivalents, accounts receivable, accounts

payable, accrued liabilities, short-term borrowings and ABL facility borrowings), excluding Term Loan borrowings, approximates the fair value of these instruments based upon their short-term nature. The fair value of Term Loan borrowings, which have an aggregate carrying value of

$902,959,

was approximately

$903,500

(Level

2

) at

December 31, 2017,

as calculated based on independent valuations whose inputs and significant value drivers are observable.

For the fair value of the assets and liabilities measured on a recurring basis,

refer to the fair value table in Note

4,

“Derivative Instruments and Hedging Activities,” to the consolidated financial statements. The fair value of all derivative contracts is classified as Level

2.

The valuation techniques used to measure the fair value of derivative contracts, all of which have counterparties with high credit ratings, were based on quoted market prices or model driven valuations using significant inputs derived from or corroborated by observable market data. The fair value of derivative contracts considers the Company’s credit risk in accordance with ASC

820

-

10.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates

The preparation of the consolidated financial statements in conformity with

U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Revenue from Contracts with Customers

. This guidance is the culmination of the FASB’s joint project with the International Accounting Standards Board to clarify the principles for recognizing revenue. The core principal of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance provides a

five

-step process that entities should follow in order to achieve that core principal. ASU

Revenue from Contracts with Customers

, becomes effective for the Company in

2018.

The guidance can be applied either on a full retrospective basis or on a modified retrospective basis in which the cumulative effect of initially applying the standard is recognized at the date of initial application. The Company has completed its assessment of the impacts the standard will have on its financial statements, and determined that the adoption does

not

have a material impact. In all material respects, the Company has identified a similar amount of performance obligations under the new guidance as compared with deliverables previously identified. As a result, the timing of revenue recognition will generally remain the same. The Company adopted the standard

January 1, 2018

and will use the full retrospective method.

In

the FASB issued ASU

Leases

. This guidance is being issued to increase transparency and comparability among organizations by requiring the recognition of lease assets and lease liabilities on the balance sheet and by disclosing key information about leasing arrangements. The guidance should be applied using a modified retrospective approach and is effective for the Company in

2019,

with early adoption permitted. The Company is currently assessing the impact the adoption of this guidance will have on the Company’s results of operations and financial position.

Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments

. This guidance is being issued to decrease diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This guidance should be applied on a retrospective basis and is effective for the Company in

2018,

with early adoption permitted. The Company does

not

believe that the adoption of this guidance will have a significant impact on the presentation of the statement of cash flows.

Intangibles – Goodwill and Other: Simplifying the Test for Goodwill Impairment

. This guidance was issued to simplify the subsequent measurement of goodwill by eliminating Step

2

of the goodwill impairment test. Under the new guidance, the recognition of a goodwill impairment charge is calculated based on the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should

not

exceed the total amount of goodwill allocated to that reporting unit. This guidance should be applied on a prospective basis and is effective for the Company in

2020.

The Company has early adopted this standard, which did

not

have a significant impact on its consolidated financial statements.

Derivatives and Hedging

–

Targeted Improvements to Accounting for Hedging Activities

. This guidance was issued 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, and to make certain targeted improvements to simplify the application of the hedge accounting guidance. For existing hedges, this guidance should be applied using a cumulative effect adjustment, while the presentation and disclosure guidance should be adopted on a prospective basis. The standard is effective for the Company in

2019,

with early adoption permitted. The Company is currently assessing the impact the adoption of this guidance will have on the Company’s results of operations and financial position.

In the

first

quarter of

Compensation – Stock Compensation: Improvements to Employee Share-Based Payment Accounting

. The primary impact of adoption is the prospective recognition of excess tax benefits or deficiencies within the provision for income taxes on the consolidated statement of comprehensive income rather than within additional paid-in capital on the consolidated balance sheet. Further, the Company has elected to continue to estimate forfeitures expected to occur to determine the amount of stock compensation expense recognized each period. The Company also elected to apply the presentation requirements for cash flows related to excess tax benefits or deficiencies prospectively. The presentation requirements for cash flows related to employee taxes paid in exchange for withheld shares had

no

impact to any period presented on the consolidated statements of cash flows as such cash flows have historically been presented as a financing activity. There were

no

cumulative effect adjustments made to equity as of the beginning of the fiscal period, as those provisions of ASU

2016

-

09

were

not

applicable or had

no

impact to the Company.

There are several other new accounting pronouncements issued by the FASB. Each of these pronouncements, as applicable, has been or will be adopted by the Company. Management does

not

believe any of these accounting pronouncements has had or will have a material impact on the Company

’s consolidated financial statements.
