PART I
 
Item 1.Business
The Company
Gibraltar Industries, Inc. (the "Company") is a leading manufacturer and distributor of building products that provide structural and architectural enhancements for residential, homes, low-rise retail, other commercialindustrial, infrastructure, renewable energy and professional buildings, industrial plants, bridgesconservation markets. Our business strategy focuses on significantly elevating and accelerating the growth and financial returns of the Company. We strive to deliver best-in-class, sustainable value creation for our shareholders for the long-term. We believe this can be achieved from a wide-varietytransformational change in the Company’s portfolio and its financial results. Our business strategy has four key elements, or "pillars," which are: operational excellence, product innovation, portfolio management, and acquisitions as a strategic accelerator.

Operational excellence is our first pillar in this strategy. 80/20 simplification ("80/20") is a core part of other structures.the operational excellence pillar and is based on the analysis that 25% of the customers typically generate 89% of the revenue in a business, and 150% of the profitability. Through the application of data analysis generated by 80/20 practice, we are focusing on our largest and best opportunities (the “80”) and eliminating complexity associated with less profitable opportunities (the “20”) in order to generate more earnings year over year, at a higher rate of return with a more efficient use of capital.

We have recently completed the third year of our multi-year simplification initiative. Since initiation of 80/20 in 2015, we have generated operating margin improvements from 80/20 simplification initiatives and have exceeded our initial five-year target ending 2019 of $25 million of pre-tax savings. We are currently in the middle innings of this 80/20 initiative, which means that there is both more work and more opportunity ahead. We are targeting greater structural changes affecting the balance sheet. We are starting the follow-on management tools of in-lining our manufacturing processes linked with market-rate-of-demand replenishment tools. These follow-on tools are focused on process manufacturing the highest-volume products include rooffor our largest customers, and foundation ventilationon a much higher level of capacity utilization. We expect these methods will yield additional benefits including lower manufacturing costs, lower inventories and fixed assets, and an even higher level of service to customers.

Product innovation is our second strategic pillar. Innovation is centered on the allocation of new and existing resources to opportunities that we believe will produce sustainable returns. Our focus is on driving top line growth with new and innovative products. We are focused on those products and technologies that have relevance to the end-user and can be differentiated from our competition. Our initiatives will be tailored toward reallocating sales and marketing talent to target specific end user groups in order to better understand their needs and the various market opportunities that may be available. This effort is

expected to produce ideas and opportunities that generate profitable growth. Our focus on innovation is centered on four markets: postal and parcel products, residential air management, infrastructure and renewable energy. These respective markets are expected to grow based on demand for: centralized mail and package storage products, rain dispersion productsparcel delivery systems; zero carbon footprint homes; the need for repairs to elevated bridges that are deficient or functionally obsolete; and roof ventilation accessories, fabricatedenergy sources not dependent on fossil fuels.

The third pillar of our strategy is portfolio management, which is a natural adjunct to the 80/20 initiative. Using the 80/20 process, we conduct strategic reviews of our customers and end markets, and allocate leadership time, capital and resources to the highest-potential platforms and businesses. During 2016, we sold our European industrial manufacturing business to a third party and initiated the divestitures of our small European residential solar racking business and U.S. bar grating product line, both of which proceeded as planned and are essentially complete. These portfolio changes have helped contribute to the Company's realization of a higher rate of return on invested capital in both 2017 and 2016. We have now acted on all near-term portfolio assessments. While we do not have any planned activities in the near future, we view portfolio management as a continuous process that will remain an important part of our strategy as we look to improve Gibraltar's long-term financial performance.

The fourth pillar of our strategy is acquisitions. We have targeted four key markets in which to make strategic acquisitions which are served by existing platforms within the Company. The existing platforms include the same areas in which we are targeting the development of innovative products: postal, parcel and storage solutions; infrastructure; residential air management; and renewable energy. These platforms are all in large markets in which the underlying trends for industrial flooring, expandedcustomer convenience and perforated metal, plus expansion jointssafety, energy-savings and structural bearingsresource conservation are of increasing importance and are expected to drive long-term demand. We believe these markets also offer the opportunity for roadwayshigher returns on our investments than those we have generated in the past. The acquisitions of Rough Brothers Manufacturing, Inc., RBI Solar, Inc., and bridges.affiliates, collectively known as "RBI" in June 2015 and more recently, Nexus Corporation ("Nexus") in October 2016 and Package Concierge in February 2017, were the direct result of this fourth pillar strategy. We also consider businesses outside of these four markets, as we continually search out opportunities to grow our business in large markets with expected growth in demand for the foreseeable future, where we can add value through our manufacturing expertise, 80/20 process and purchasing synergies.
We serve
The Company serves customers primarily throughout North America and, Europe, and, to a lesser extent, in Asia, Africa, Australia, and Central and South America.Asia.

We believe that weour operating segments have established a reputationreputations as an industry leader in both of our operating segmentsleaders with respect to quality, service and innovation and have achieved strong competitive positions in our markets. We attribute ourtheir competitive standing in the markets primarily to the following competitive strengths:
Leading market share. We have a leading market position in many of the products and services we offer, and we estimate that a majority of our net sales for the year ended December 31, 20142017 were derived from the sale of products in which we had one of the leading U.S. market shares. We believe we have leading market shares in fourfive distinct product families: roof-related ventilation; postal and parcel storage; bar grating; structural bearings and expansion joints for bridges and other structures.structures; institutional and retail greenhouses; and fixed-tilt ground mount racking for photovoltaic (PV) solar systems.
Provider of value-added products and related services. We increasingly focus on providing innovative value-added products and related services, such as centralized mail systems and electronic package storage solutions, expansion joints and structural bearings for roadways and bridges, roof and foundation ventilation products, solar racking systems, and greenhouses which can solve end customer needs while also helping to improve our margins and profitability. WeOur products use complex and demanding production and treatment processes that require advanced production equipment, sophisticated technology and exacting quality control measures.measures, along with specialized design and engineering skills. We have also targetedfocus our acquisition strategy on manufacturers of value-addedoffering engineered products and services in key growth platforms.

Strong liquidity profile. We had no borrowings understrive to manage our revolving credit facility duringcash resources to ensure we have sufficient liquidity to support the yearseasonality of our businesses, potential downturns in economic activity, and to fund growth initiatives. During the years ended December 31, 2014,2017 and 2016, we purchased Package Concierge for approximately $19 million and Nexus for approximately $24 million, respectively, funded by our cash on hand. Our liquidity as of December 31, 20142017 was $209$511 million, including $111$222 million of cash and $98$289 million of availability under our revolving credit facility. We believe that our current low leverage and increasedample liquidity allowsallow us to successfully manage our business, meet the demands of our customers, weather the cyclicality of certain end markets and take advantage of growth opportunities.

History of growth through acquisitions. Over the last decade, we have grown through acquisitions, such as D.S. Brown (expansion joints and bearing for roads and bridges), Florence Manufacturing (mail storage) and Alabama Metal Industries Corporation (bar grating, expanded and perforated metal products), to help diversify our products and customers while growing our net sales and earnings, and improving our operating characteristics.
Recent developments
Structured succession plan. AsOn February 22, 2017, the Company acquired all of the outstanding stock of Package Concierge for $19 million. The acquisition was financed through cash on hand. Package Concierge is a leading provider of multifamily electronic package delivery locker systems in the United States. The results of operations of Package Concierge have been included within the Company's Residential Products segment of the Company's consolidated financial statements from the date of acquisition.
On December 2, 2016, as part of a multi-year strategy developed by the board, an executive search committee was created to execute the Company’s succession plan. The executive search committee consisted of board members who used an outside firm to identify potential candidates to fill the vacated President and Chief Operating Officer role and eventually assume the Chief Executive Office role. After an extensive search process, Frank Heard was hired in May 2014 as President and Chief Operating Officer. Mr. Heard joined our company with extensive experience in the building products industry from his 32 years of employment at Illinois Tool Works, Inc. In December 2014, the board announced the remainder of the succession plan and named Mr. Heard as the President and Chief Executive Officer effective January 1, 2015.
Mr. Heard succeeds Brian Lipke who had been our Chief Executive Officer (CEO) since 1987, the Chairman of our Board since 1992 and a director since the Company’s initial public offering. Mr. Lipke announced his retirement as CEO in December 2014 and will continue to serve as Executive Chairman of the Board until May 31, 2015 when he will retire from the Board. At that time, William Montague, the Company’s Lead Independent Director will assume the Chairman role.
In conjunction with the succession plan, several transitions were made to the Board of Directors. Two directors retired at the end of 2014 and two other directors, including Mr. Lipke, will retire in May 2015. Three new board members were elected and began service during 2014 in order to facilitate a smooth transition upon the retirement of the seasoned directors. These new board members bring a complement of industry and governmental experience to the board. Mr. Heard was also elected a director ofits portfolio management initiative, the Company effective January 1, 2015.

Experienced Management Team. Our executive management team is composed of talentedannounced its intentions to exit its U.S. bar grating product line and experienced managers possessing broad experience in operational excellence, new product development, and driving profitable growth gained over multipleits European residential solar racking business, cycles. Along withwithin the employment of Mr. Heard in 2014 as President and subsequent appointment as Chief Executive Officer, we made other senior leadership changes, including the hiring and appointment of Kevin Viravec, theCompany’s Industrial and Infrastructure Products, President, alongand Renewable Energy and Conservation, segments, respectively. On February 6, 2017, the Company completed the sale of substantially all of its U.S. bar grating product line assets to a third party. In addition, the Company shut down the operations of its European residential solar racking business during the first quarter of 2017. These businesses contributed a combined $75 million in revenue and pre-tax operating losses of $6 million in 2016. This initiative resulted in the sale and closing of 3 facilities in 2017.
On October 11, 2016, the Company acquired all of the outstanding stock of Nexus for $24 million. The acquisition was financed through cash on hand. Nexus is a leading provider of commercial-scale greenhouses to customers in the United States. The results of operations of Nexus have been included within the Renewable Energy and Conservation segment of the Company's consolidated financial statements from the date of acquisition.
On April 15, 2016, the Company sold its European industrial manufacturing business to a third party for net of cash proceeds of $8 million. This business, which supplied expanded metal products for filtration and other applications, contributed $36 million in revenue to the Company's Industrial & Infrastructure Products segment in 2015 and had nearly break-even operating results. The divestiture of this business is in alignment with the hiringCompany's portfolio management assessments.
On June 9, 2015, the Company acquired RBI for $148 million. RBI is one of Paul Plourde,North America’s fastest-growing providers of solar racking solutions and is also one of the largest manufacturers of commercial greenhouses in the United States. RBI is a newly created position as leaderfull service provider that designs, engineers, manufactures and installs solar racking systems for solar developers and power companies. In addition, RBI designs, engineers, manufactures and erects greenhouses for commercial, institutional and retail customers. The acquisition of business development. Other developments include changesRBI has enabled the Company to leverage its expertise in leadershipstructural metals manufacturing, materials sourcing and logistics to help meet the growing demand for solar racking solutions. The results of RBI have been included in the Company’s consolidated financial results since the date of the acquisition. The acquisition was financed through cash on hand and short-term borrowings under our revolving credit facility.
Customers and Products
Our customers are located primarily throughout North America and, to a lesser extent, Asia. One customer, a home improvement retailer which purchases from both the Residential Products segment and Renewable Energy and Conservation segment, represented 12% of our consolidated net sales for 2017 and 11% for both 2016 and 2015. No other customer in any segment accounted for more than 10% of our postal and parcelconsolidated net sales.
Our products are primarily distributed to our customers using common carriers. We maintain distribution centers that complement our manufacturing plants from which we ship products and our ventilation and roofing-related products, where Stephen Duffy and Charles Jerasa assumed new leadership positions, respectively.
Operational excellence. Our strategy is to position Gibraltar as a low-cost provider and a market share leader in product areas that offer the opportunity for sales growth and margin enhancement over the long-term. We focus on operational excellence, including lean initiatives throughout the Company to position Gibraltar as our customers’ low-cost provider of the products we offer. We continuously seek to improve ourensure on-time delivery quality and service to position Gibraltar as a preferred supplier to our customers. During recent years, Gibraltar invested in new enterprise resource planning (“ERP”) systems which, among other things, have enabled us to more effectively manage our inventory, forecast customer orders, improve supply chain management and respond more timely to volatile raw material costs. At the same time, we have significantly reduced our working capital levels while maintaining a high level of customer service.efficiency within our distribution process. Our customers and product offerings by segment are described below.
Economic TrendsResidential Products
End markets served by our business are subject to economic conditions which include but are not limited to interest rates, commodity costs, demand forOur Residential Products segment services the residential construction, demand for repair and remodeling government funding, and the level of industrial construction and transportation infrastructure projects.
During 2014 and 2013, residentialhousing construction markets continued to recoverin North America with housing starts approaching 1.0 million in 2014. Residential repairproducts including roof and remodel activity also continued to improve over the past two years; however, re-roofing activity, which correlates to demand for our roof-relatedfoundation ventilation products, declined from 2013. While very little market lift from the residential

housing market was experienced during 2014, we generated incremental sales of our centralized mail storagesystems and electronic package solutions, out-door living products as postal authorities continue transitioning from door-to-door delivery.
In our Industrial and Infrastructure Products segment, sales declined slightly for 2014. The sales decrease was primarily impacted by continuing uncertainty of government funding for U.S. transportation projects. The current federal appropriation was a nine-month extension ending May 2015. As a result, sales of our bearings and expansion joints for bridges and elevated highways decreased in 2014 compared to 2013.
Commodity raw material prices for materials such as steel, aluminum and resins, have also fluctuated during the past several years. These fluctuations impact the cost of raw materials we purchase and the pricing we offer to our customers. Volatility in commodity prices in combination with pressure to reduce prices to customers over the past few years have led to declining margins on our product sales.
Industry Overview
Our business occupies an intermediate market between the primary steel, aluminum, resin,(retractable sun-shades), rain dispersion products and other basic material producersroofing and the wholesale, retail building supply, manufacturing, and highway construction markets. The primary material producers typically focus on producing high volumes of their product. We purchase raw materials from these producers and, through various production processes, convert these raw materials into specialized products for use in the construction or repair and remodel ofrelated accessories.

We maintain our equipment withaccording to a thorough preventive maintenance program, including in-house tool and die shops, allowing us to meet the demanding service requirements of many of our customers.

OverallRenewable Energy and Conservation
Gibraltar focuses on operational excellence by makingThe Renewable Energy and Conservation segment is primarily a designer and manufacturer of fully-engineered solutions for solar mounting systems and greenhouse structures. This segment offers a fully integrated approach to the design, engineering, manufacturing and installation of solar racking systems and commercial, institutional, and retail greenhouse structures servicing customers, such as solar owners and developers, retail garden centers, conservatories and botanical gardens, commercial growers, and schools and universities. We have 7 manufacturing facilities and 2 distribution centers and operate in the United States, China and Japan.
An integral part of each customer project is the fabrication of specifically designed metal structures for highly-engineered applications including: racking for ground-mounted solar arrays; carports that integrate solar PV panels; as well as commercial-scale greenhouses and other glass structures. Both the solar racking and greenhouse projects involve holding glass and plastic to metal and use the same raw materials including steel and aluminum. Most of our production process as efficient as possible without compromising the quality our customers expect from us. Our focus on efficiency relies upon continuous improvement at our plantsis completed using CNC machines, roll forming machines, laser cutters and distribution centers where we have continued lean manufacturing practices. Additionally, we have implemented ERP systems that allow for just-in-time delivery of materials, efficient production planning,other fabrication tools. The structural metal components are designed, engineered, fabricated and eliminate manual effortsinstalled in the manufacturing process. Improvements in our manufacturing process have enabled Gibraltar to better control manufacturing costs while focusing on new product developmentaccordance with applicable structural steel and quality. Continued focus on operational excellence will remain a significant initiative as Gibraltar strives to be the low-cost manufacturer of our products.
Quality Assurancealuminum guidelines.
We place great importancestrive to improve our offerings of products by introducing new products, enhancing existing products, adjusting product specifications to respond to commercial building codes and regulatory changes, and providing solutions to contractors and end users. New products introduced in recent years include metal framed canopy structures for car washes and pool enclosures, and solar racking systems for carports and canopies. Our car washes and canopy structures serve a market preference for light- transparent structures. Solar racking systems for carports serve as protection for cars from the effects of the sun and intense heat while providing a renewable energy resource. Similarly, solar racking systems installed on idle land, such as solid waste landfills, converts such land into a useful property by providing our customers with high-quality products for use in critical construction applications. We carefully select our raw material vendorspower generating capabilities.
Engineering and use inspection and analysis to maintain our quality standards so our products meet critical customer specifications. To meet customer specifications, we use documented procedures utilizing statistical process control systems linked directly to processing equipment to monitor many stages of production. A number of our facilities’ quality systems are registered under ISO 9001, an internationally recognized set of quality-assurance standards, and other industry standards. Gibraltar believes ISO registration is important as the disciplines it promotes help ensure the high quality products our customers expect.
Technical Services
WeOur businesses employ a staff of engineers and other technical personnel and maintainto perform a variety of key tasks. These personnel staff fully-equipped, modern laboratories to support our operations. These laboratories enable us to verify, analyze, and document the physical, chemical, metallurgical, and mechanical

properties of our raw materials and products. In addition, our engineering staff employs a range of drafting software to design highly specialized and technically precise products. In our Renewable Energy and Conservation segment, drawings are designed, signed and sealed by licensed engineers. Technical service personnel also work in conjunction with our sales force to determine the types of products and services required forthat suit the particular needs of our customers.
Suppliers and Raw Materials
Our business is required to maintain sufficient quantities of raw material inventory in order to accommodate our customers’ short lead times and just-in-time delivery requirements.times. Accordingly, we plan our purchases to maintain raw materials at sufficient levels to satisfy the anticipated needs of our customers. We have implemented ERPenterprise resource planning systems to better manage our inventory, forecast customer orders, enable efficient supply chain management, and allow for more timely counter-measures to changing customer demand and market conditions.
The primary raw materials we purchase are flat-rolled and plate steel, aluminum, and resins. We purchase flat-rolled and plate steel and aluminum at regular intervals on an as-needed basis, primarily from the major North American mills, as well as, a limited amount from domestic service centers and foreign steel importers. Substantially all of our resins are purchased from domestic vendors, primarily through distributors, with a small amount direct from manufacturers. Supply has historically been adequate from these sources to fulfill our needs. Because of our strategy to develop longstanding relationships in our supply chain, we have been able to adjust our deliveries of raw materials to match our required inventory positions to support our on-time deliveries to customers while allowing us to manage our investment in inventory and working capital.
The cost of our raw material purchases of steel, aluminum, and resins is significantly linked to commodity markets. The markets for commodities are highly cyclical and the costs of purchasing these raw materials can be volatile due to a number of factors including general economic conditions, domestic and worldwide demand, labor costs, competition, import duties, tariffs, and currency exchange rates. Changes in commodity costs not only impact the cost of our raw materials but also influence the prices we offer our customers. We have largely managed fluctuations in the market by maintaining lean inventory levels and increasing the efficiency of our manufacturing processes, however in limited situations, where we have fixed price contacts to supply goods covering multiple quarters, we have used hedge contracts to mitigate the risk of changes in commodity costs.
We purchase natural gas and electricity from suppliers in proximity to our operations.
We have no long-term contractual commitments with our suppliers. Management continually examines and improves our purchasing practices across our geographically dispersed facilities in order to streamline purchasing across similar commodities.
We purchase natural gas and electricity from suppliers in proximity to our operations.

We have organized sales teams to focus on specific customers and national accounts through which we provide enhanced supply solutions and improve our ability to increase the number of products that we sell. Our sales staff works with certain retail customers to optimize shelf space for our products which is expected to increase sales at these locations. Our sales regularly involve competitive bidding processes, and our reputation for meeting delivery time lines and strict specifications make us a preferred provider for many customers.
We focus on providing our customers with industry leading customer service. Our business units generate numerous publications, catalogs, and other printed materials to facilitate the ordering process. In addition, we provide our retail customers are provided with point-of-sale marketing aids to encourage consumer spending on our products in their stores. Continual communication with our customers allows us to understand their concerns and provides us with the capabilityopportunity to identify solutions that will meet our customers’their needs. We offer our customers prompt service and short lead times because we have the ability to successfully meet short deadlines. Gibraltar isare able to meet our customers’ demand requirements due to our efficient manufacturing processes and extensive distribution network.

Customers and Distribution
Our customers are located primarily throughout North America and Europe, and, to a lesser extent, in Asia, Africa, Australia, Central and South America. Our Residential Products segment operates principally in the residential new construction and repair and remodeling markets. Our Industrial and Infrastructure Products segment serves a variety of commercial construction and industrial markets; bridge and highway construction markets; and a variety of industrial markets. A majority of our products are sold through sales channels. Major customers include home improvement retailers, building product distributors, residential contractors, and postal services for our Residential Products segment. Discrete and process manufacturers, transportation contractors and automotive suppliers are major customers in our Industrial and Infrastructure Products segment. One customer within our Residential Products segment, a home improvement retailer, represented 12% of our consolidated net sales for 2014, 2013, and 2012, respectively. No other customer in either segment accounted for more than 10% of our consolidated net sales.
Our products are distributed to our customers using common carriers and our own fleet of trucks. We maintain distribution centers that complement our manufacturing plants from which we ship products and ensure on-time delivery while maintaining efficiency within our distribution process. In recent years, we have consolidated a number of distribution centers. Increased efficiency within our distribution network allowed us to eliminate costs from our business while continuing to provide excellent service to our customers.
Backlog
While the majority of our products have short lead time order cycles, we have aggregated approximately $153 million of backlog at December 31, 2017. The backlog primarily relates to certain business units have backlog aggregating nearly $107 million at December 31, 2014.in our Industrial and Infrastructure Products and our Renewable Energy and Conservation segments. We believe that the majority of our backlog will be shipped, completed and installed during 2015.2018.
Competition
GibraltarThe Company operates in highly competitive markets. We compete against several competitors in all three of our Residential Products segment and Industrial and Infrastructure Products segment, and, aresegments with different competitors in each major product category. A few of our competitors may be larger, have greater financial resources, or have less financial leverage than we do. As a result, these competitors may be better positioned to respond to any downward pricing pressure or other adverse economic or industry conditions or to identify and acquire companies or product lines compatible with their business.
We compete with competitors based on the range of products offered, quality, price, and delivery.delivery, as well as, serving as a full service provider for project management in certain segments. Although some of our competitors are large companies, the majority are small to medium-sized and do not offer the large range of building products that we do.
The prices paid for raw materials used in our operations, primarily steel, aluminum, and resins, are volatile due to a number of factors beyond our control, including but not limited to supply shortages, general industry and economic conditions, labor costs, import duties, tariffs, and currency exchange rates. Although we have strategies to help mitigate the volatility in raw material costs, such as reducing inventory levels, our competitors who chose not to maintain inventories as large as ours may be better able to mitigate the effects of this volatility and, thereby, compete effectively against us on product price.offer.
We believe our broad range of products, high quality, and sustained ability to meet exacting customer delivery requirements gives us a competitive advantage over many of our competitors.

Governmental Regulation
Our manufacturing facilities and distribution centers are subject to many federal, state, and local requirements relating to the protection of the environment. Our production processes involve the use someof environmentally sensitive materials. For example, we lubricate our machines with oil and use oil baths to treat some of our products. While we cannot guarantee that we will not incur material expenses to comply with environmental requirements, weWe believe that we operate our business in material compliance with all federal, state and local environmental laws and regulations, and do not anticipate any material expenditures to continue to meet environmental requirements, and do not believe that future compliance with such laws and regulations will have a material adverse effect on our financial condition or results of operations.operations to maintain compliance with such laws and regulations. However, we could incur operating costs or capital expenditures in complying with new or more stringent environmental requirements in the future or with current requirements if they are applied to our manufacturing facilities or distribution centers in a way we do not anticipate. In addition, new or more stringent regulation of our energy suppliers could cause them to increase the price of energy they supply us.energy.
Our operations are also governed by many other laws and regulations covering our labor relationships, the import and export of goods, the zoning of our facilities, taxes, our general business practices, and other matters. We believe that we are in material compliance with these laws and regulations and do not believe that future compliance with such laws and regulations will have a material adverse effect on our financial condition or results of operations.

Item 1A.Risk Factors
FutureOur business, financial condition and results of operations, and the market price for Gibraltar’sthe Company's common shares are subject to numerous risks, many of which are driven by factors that cannot be controlled or predicted. The following discussion, as well as, other sections of this Annual Report on Form 10-K, including “PART“Part II, Item 7. —7, Management’s Discussion and Analysis of Financial Condition and Results of Operations,” describe certain business risks.and other risks affecting the Company. Consideration should be given to the risk factors described below as well as those in the Safe Harbor Statement at the beginning of this Annual Report on Form 10-K, in conjunction with reviewing the forward-looking statements and other information contained in this Annual Report on Form 10-K. These risks are not the only risks we face. Our business operations and market for our securities could also be adversely affected by additional factors that are not presently known to us or that we currently consider to be immaterial in our operations.

Macroeconomic factors outside of our control may adversely affect our business, our industry, and the businesses and industries of many of our customer and supplierssuppliers.
Macroeconomic factors may have a significant impact on our business, including our ability to generate profitable margins, customer demand and the availability of credit and other capital. The impactscapital, affecting our ability to generate profitable margins. Our operations are subject to the effects of futuredomestic and international economic conditions including government monetary and government measures to aid economic growth,trade policies, tax laws and regulations, as well as, the growingrelative debt levels of the United StatesU.S. and the other countries especiallywhere we sell our products. Significant fluctuations in Europe,energy costs have, and may continue to, be unknown. The changing costs of energy, in particular oil, could negatively impact demand for our bar grating and expanded metal products. Tariffs placed on imported products used by our customers, such as solar panels, may negatively impact demand for our solar racking systems. In addition, the strengthening offluctuations in the U.S. dollar impacts the prices we charge and costs we incur to export and import products.
We are unable to predict the strength, pace or sustainabilityimpact on our business of changes in domestic and international economic changes orconditions. The markets in which we operate have been challenging in the effects of government intervention or debt levels. The construction market has shown signs of stabilizing. However, global economic conditions remain fragile,past, and the possibility remains that the domestic or global economies, or certain industry sectors of those economies that are key to our sales, may continue to be slow or could further deteriorate, which could result in a corresponding decrease in demand for our products and negatively impact our results of operations and financial condition.
Our amount of indebtednessleverage and debt service obligations could adversely affect our ability to raise additional capital to fund our operations, limit our ability to react to changes in the economy or our industry, and prevent us from meeting our obligations.

Our ability to make scheduled debt service payments or to refinance our debt obligations depends on our financial condition and operating performance, which are subject to prevailing economic and competitive conditions and to certain financial, business, legislative, regulatory and other factors beyond our control. We may be unable to maintain a level of cash flows from operating activities sufficient to permit us to pay thepaying principal, premium, if any, and interest on our indebtedness.indebtedness;
If our cash flows and capital resources are insufficient to fund our debt service obligations, we could face substantial liquidity problems and could be forced to reduce or delay investments and capital expenditures, or to dispose of material assets or operations, seek additional debt or equity capital or restructure or refinance our indebtedness. We may not be able to affect any such alternative measures, if necessary, on commercially reasonable terms or at all and, even if successful, those alternative actions may not allow us to meet our scheduled debt service obligations. The credit agreement governing the revolving credit facility and the indenture that governs the 6.25% Notes restrictsLimiting our ability to dispose of assets and use the proceedscash flow from those dispositions and may also restrict our ability to raise debtoperations or equity capital to be used to repay other indebtedness when it becomes due. We may not be able to consummate those dispositions or to obtain proceeds in an amount sufficient to meet any debt service obligations then due.
If we cannot make scheduled payments on our debt, we will be in default and, as a result:
our debt holders could declare all outstanding principal and interest to be due and payable;
the lenders under the revolving credit facility could terminate their commitments to loan money, and foreclose against the assets securing their borrowings; and
we could be forced into bankruptcy or liquidation.
Relative to current indebtedness levels, we may still be able to incur substantially more debt, including debt under our revolving credit facility. This could further exacerbate the risks described above.
We have a Senior Credit Agreement that provides the Company with a revolving credit facility commitment up to $200 million with borrowings limited to the lesser of (i) $200 million or (ii) a borrowing base determined by reference to the trade receivables, inventories, and property, plant, and equipment of our significant domestic subsidiaries. We had no borrowings during 2014, and as of December 31, 2014, we had $98 million of availability under our revolving credit facility. Under the terms of our Senior Credit Agreement, we are required to repay all amounts outstanding under the revolving credit facility by October 10, 2016. Our principal operating subsidiary, Gibraltar Steel Corporation of New York, is also a borrower under the Senior Credit Agreement and the full amount of our commitments under the revolving credit facility may be borrowed by that subsidiary.
We also have $210.0 million of 6.25% Notes that are due February 1, 2021.

Our substantial degree of indebtedness could have other important consequences, including the following:
it may limit our ability to obtain additional debt or equity financing for working capital, capital expenditures, product development, debt service requirements, acquisitions, and general corporate or other purposes;
a substantial portion of our cash flows from operations have been and are expected to be dedicated to the payment of interestexecute on our indebtedness and may not be available for other purposes, including our operations, capital expenditures, and future business opportunities;

Restrictive
Our debt instruments impose operational and financial restrictive covenants which may adversely affectlimit our operations.operational and financial prospects.
The Senior Credit Agreement and the indenture governing our 6.25% Notes contain various covenants that limit our ability to, among other things:
incur additional debt or provide guarantees in respect of obligations of other persons;
pay dividends or distributions or redeem or repurchase capital stock;
prepay, redeem, or repurchase debt;
make loans, investments including acquisitions, and capital expenditures;

In addition, the restrictive covenants in the Senior Credit Agreement include a single financial covenant that requires the Company to maintain a minimum fixed charge coverage ratio of 1.25 to 1.00. Our ability to meet the restrictive covenants in the future can be affected by events beyond our control and we cannot assure you that we will meet this financial ratio. A breach of any ofviolate these covenants, would result in a default under the Senior Credit Agreement. Upon the occurrence of an event of default under the Senior Credit Agreement, we would attempt to receive a waiver from our lenders, which could result in us incurring additional financing fees that would be costly and adversely affect our profitability and cash flows. IfWe may also incur additional debt for acquisitions, operations and capital expenditures that could adversely impact our ability to meet these covenants.
We apply judgments and make estimates in accounting for contracts, and changes in these judgments or estimates may have significant impacts on our earnings.

Due to the lenderssubstantial judgments applied and estimations involved with this process, our actual results could electdiffer materially or could be settled unfavorably from our estimates. Revenue representing approximately 28% and 26% of 2017 and 2016 sales, respectively, were accounted for using the percentage of completion, cost-to-cost method of accounting. Refer to declare all amounts outstanding under such facility to“Critical Accounting Estimates” within Item 7 of this Form 10-K for more detail of how our financial statements can be immediately due and payable and terminate all commitments to extend further credit. If such event of default and election occurs, the lenders under the Senior Credit Agreement would be entitled to be paid before current 6.25% Note holders receive any payment under our notes. In addition, if we were unable to repay those amounts, the lenders under the Senior Credit Agreement could proceed against the collateral granted to them to secure that indebtedness. We have pledged substantially all our assets as collateral under the Senior Credit Agreement. If the lenders under the Senior Credit Agreement accelerate the repayment of borrowings, we cannot assure you that we will have sufficient assets to repay debt outstanding under the Senior Credit Agreement and our other indebtedness, including our 6.25% Notes, or borrow sufficient funds to refinance such indebtedness. An acceleration of the amounts outstanding under the Senior Credit Agreement would result in an event of default under the 6.25% Notes which would then entitle the holders thereof to accelerate and demand repayment of the 6.25% Notes as well.

New construction and home repair and remodeling markets account for a significant portion of our sales, and any substantial reduction in demand from these activities is likely to adversely affect our profitability and cash flow.
The recent downturn in the economy, the disruption in capital and credit markets, declining real estate values, high unemployment rates, and reduced consumer confidence and spending have caused significant reductions in demand from our end markets in general and, in particular, the construction and home repair and remodeling markets. The construction industry and home repair and remodeling markets in North America have shown signs of stabilizing from further erosion. However, these markets are still depressed compared to historic norms, and we cannot predict the strength, pace or sustainability of recovery in these markets.
Our largest customers are retail home improvement centers and wholesale distributors who largely sell into the residential housing market. Our largest customer accounted for approximately 12% of our consolidated net sales during 2014, 2013, and 2012, respectively.
A loss of sales, whether due to decreased demand from the construction market, the home repair and remodel market,end markets we serve or from any significant customer in these markets, or a decrease in the prices that we can realize from sales of our products to customers in these markets, could adversely affect our profitability and cash flows. The end markets we serve have been and are expected to continue to be cyclical, with product demand based on numerous factors such as seasonal weather, availability of credit, interest rates, general economic conditions, consumer confidence, unemployment levels, and other factors beyond our control. The economic conditions experienced in the earlier years of the recession negatively affected all of these factors. If demand for the products we sell to these markets were to decline further, this could negatively affect our sales, financial results, and cash flows in the future.

We rely onor a few customers for a significant portion of our net sales. The loss of those customers would adversely affect our business.
Some of our customers are material to our business and results of operations. Our ten largest customers accounted for approximately 31%, 29%, and 30% of our net sales during 2014, 2013, and 2012, respectively. Our percentage of net sales to our major customers may increase if we are successful in executing our strategy of broadening the range of products we sell to existing customers. In such an event, or in the event of any consolidation of our customers, our net sales may be increasingly sensitive to deterioration in the financial condition of, or other adverse developments with, one or more of our largest customers. Similarly, many of our customers have also experienced and continue to experience challenging financial conditions. The financial difficulties of certain customers and/or their failure to obtain credit or otherwise improve their overall financial condition could result in numerous changes within the markets we serve, reduced demand, decreased production, changes in product mix, unfavorable changes in the prices, terms or conditions we are able to obtain and other changes that may result in decreased purchases from us and otherwise negatively impact our business. These customers are also able to exert pricing and other influences on us, requiring us to market, deliver, and promote our products in a manner that may be more costly to us. Moreover, we generally do not have long-term contracts with our customers. As a result, although our customers periodically provide indications of their product needs and purchases, they generally purchase our products on an order-by-order basis, and the relationship, as well as particular orders, can be terminated at any time. The loss, bankruptcy, or significant decrease in business from any of our major customers, wouldcould have a materialsignificant adverse effect on our business, results of operations,profitability and cash flow. While we have takenflows. Our ten largest customers accounted for approximately 36%, 30%, and will continue to take steps intended to mitigate34%, of our net sales

during 2017, 2016, and 2015, respectively, with our largest customer, a retail home improvement center, accounting for approximately 12% of our consolidated net sales during 2017 and 11% of our consolidated net sales for both 2016 and 2015.

The volatility of the impact of financial difficulties and potential bankruptcy filings by our customers, these matters could have a negative impactcommodity market on our business.pricing of our principal raw materials, and the highly competitive market environment in which we do business could significantly impact our gross profit, net income, and cash flow.
Our principal raw materials are commodity products consisting of steel, aluminum, and resins, for which, at times, availability and pricing can be volatile due to a number of factors beyond our control, including general economic conditions, domestic and worldwide demand, labor costs, competition, import duties, tariffs, and currency exchange rates. Commodity price fluctuations and increased competition could force us to lower our prices or to offer additional services or enhanced products at a higher cost to us, which could reduce our gross profit, net income, and cash flow and cause us to lose market share.
Our business is highly competitive and increased competition could reduce our gross profit, net income, and cash flow.
The principal markets that we serve are highly competitive. Competition is based primarily on product functionality, quality, price, raw material and inventory availability, and the ability to meet delivery schedules dictated by customers. We compete in our principal markets with companies of various sizes, some of which have greater financial and other resources than we do and some of which have better established brand names in the markets we serve. Increased competition could force us to lower our prices or to offer additional services or enhanced products at a higher cost to us, which could reduce our gross profit, net income, and cash flow and cause us to lose market share.

Cyber-based risks, in particular, are evolving and include, but are not limited to, both attacks on our IT infrastructure and attacks on the IT infrastructure of third parties (both on premises and in the cloud) attempting to gain unauthorized access to our confidential or other proprietary information, classified information, or information relating to our employees, customers and other third parties.

Additionally, we maintain moderateadopt measures designed to high levels of inventoriesenhance our protection, detection, response, and recovery capabilities, and to accommodate the short lead times and just-in-time delivery requirements of our customers. Accordingly, we purchase raw materials on a regular basis in an effort to maintain our inventory at levels that we believe are sufficient to satisfy the anticipated needs of our customers based upon expected buying practices and market conditions. In an environment of increasing raw material prices, competitive conditions will impact how much of the steel price increases we can pass onmitigate potential risks to our customers.

In the event of rapidly decreasing raw material prices, we may be left to absorb the cost of higher cost inventory as customers receive reduced pricing related to decreases in raw material costs. To the extent we are unable to match our costs to purchase raw materials to prices givenor potential liability, and/or damage to our customers, the profitability of our business and resulting cash flows could be adversely affected.
Lead time and the cost of our products could increase if we were to suddenly lose a few of our primary suppliers.
If, for any reason, our primary suppliers of steel, aluminum, resins, or other materials should curtail or discontinue deliveries to us in quantities we need and at prices that are competitive, our business could suffer. Our top ten suppliers accounted for 29% of our purchases during 2014. We could be significantly and adversely affected if delivery were disrupted from a major supplier or several suppliers. In addition, we do not have long-term contracts withreputation, any of our suppliers. If, in the future, we were unable to obtain sufficient amounts of the necessary metals at competitive prices and on a timely basis from our traditional suppliers, we may not be able to obtain such metals from alternative sources at competitive prices to meet our delivery schedules, which wouldcould have a material adverse effect on our competitive position, results profitability,of operations, cash flows or financial condition. Due to the evolving nature of such risks, the impact of any potential incident cannot be predicted.

If the subcontractors and cash flow.
Increases in energy and freight prices would increase our operating costs andsuppliers we may be unable to pass all these increases on to our customers in the form of higher prices for our products. We use energy to manufacture and transport our products. In particular, our plants use considerable amounts of electricity and our freight expenses include the cost of fuel to operate trucks. Our operating costs increase if energy costs rise. Although werely upon do not believe we have experienced materially higher energy costs as a result of new or more stringent environmental regulations ofperform to their contractual obligations, our energy suppliers, such regulations could increase the cost of generating energy that is passed on to us. We do not hedge our exposure to higher prices via energy futures contracts. During periods of higher freight and energy costs, we may not be able to recover our operating cost increases through customer price increases without reducing demand for our products. Increases in energy prices may reduce our profitabilityrevenues and cash flows ifwould be adversely affected.

Our strategy depends on identification, management and successful integration of future acquisitions.
Historically, we have grown through a combination of internal growth plus external expansion through acquisitions such as the acquisitions made during the last three years.acquisitions. Although we intend to actively pursuecontinue to seek additional acquisition opportunities in accordance with our growthbusiness strategy, in the future, we cannot provide any assurance that we will be able to identify appropriate acquisition candidates, or, if we do, that we will be able to negotiate successfully the terms of an acquisition, finance the acquisition or integrate the acquired business profitablyacquisition into our existing operations. Integration of an acquired business could disrupt our business by diverting management away from other day-to-day operations and could result in liabilities that were not anticipated. Further, failureFailure to integrate any acquisition successfully may cause significant operating inefficiencies, result in the incurring of unforeseen obligations or loss of customers and could adversely affect our profitability and our ability to repay our outstanding indebtedness.profitability.

We are subject to information system security risksSystems integration and systems integrationimplementation issues could disrupt our internal operations.
We are dependent uponIn connection with the acquisitions we make, we customarily must integrate legacy information technology systems of the acquired business with our information technology infrastructure, and networks in connection with a variety of business activities, includingsome cases, implement new information technology systems for the distribution of information internally and also to our customers and suppliers.business. In addition, as the functionality of available information systems increases, we collect and storemay need to implement significant amountsupgrades or even replace some of confidential data and information. Thisour primary information technology systems across significant parts of our businesses and data is subject to theft, damage, or interruption from a variety of sources, including but not limited to natural disasters, accidents, power disruptions, telecommunications failures, acts of terrorism or war, malicious computer code, such as worms, viruses and Trojan horses, security breaches, and defects in design.operations. The implementation of new information technology solutions could lead to interruptions of information flow internally and to our customers and suppliers while the implementation project is being completed. We implemented new systems during the past three years at several business units. Various measures have been taken to manage our risks related to information system and network disruptions and to prevent attempts to gain unauthorized access through the internet to our information systems. Nevertheless, such measures cannot provide absolute security due to employee error, malfeasance, faulty password management, or other irregularities. A security breach, system failure, orAny failure to integrate legacy systems of acquisitions or to implement new systems properly could negatively impact our operations and financial results. In addition, cyber attacks could threaten, or even impair, the integrity and value of our trade secrets and other sensitive intellectual property, as well as reveal personally identifiable information of our employees and customers.
Our principal stockholders have the ability to exert significant influence in matters requiring a stockholder vote and could delay, deter, or prevent a change in control of the Company.
Approximately 5% of our outstanding common stock, including shares of common stock issuable under options and similar compensatory instruments granted which are exercisable, or which vested or will vest within 60 days, are owned by Brian J. Lipke, the Chairman of the Board of the Company, Eric R. Lipke, Neil E. Lipke, Meredith A. Lipke, and the estate of Curtis W. Lipke, all of whom are siblings, and certain trusts for the benefit of each of them and their families. As a result, the Lipke family has influence over all actions requiring stockholder approval, including the election of our board of directors. In deciding how to vote on such matters, the Lipke family may be influenced by interests that conflict with the interests of other shareholders.
We depend on our senior management team, and the unexpected loss of any member could adversely affect our operations.
Our success is dependent on the management and leadership skills of our senior executive and divisional management teams. The unexpected loss of any of these individuals, or anour inability to attract and retain additional personnel could prevent us from successfully executing our business strategy. We cannot assure you that we will be able to retain our existing senior management personnel or to attract additional qualified personnel when needed. We have not entered into employment agreements with any of our senior management personnel other than Brian J. Lipke, our Executive Chairman of the Board, and Frank G. Heard, our President and Chief Executive Officer.

We could incur substantial costs in order to comply with, or to address any violations of, environmental, health and safety laws.
Our operations and facilities are subject to a variety of stringent federal, state, local, and foreign laws and regulations relating to the protection of the environment and human health and safety. Compliance with these laws and regulations sometimes involves substantial operating costs and capital expenditures, and any failure to maintain or achieve compliance with these laws and regulations or with the permits required for our operations could result in substantial costs, such as fines and civil or criminal sanctions, third-party claims for property damage or personal injury, cleanup costs or temporary or permanent discontinuance of operations, including claims arising from the businesses and facilities that we have sold. We sometimes use hazardous and regulated substances such as petroleum products, hydraulic fluids, and solvents in our operations and are responsible for the proper handling, storage and disposal of hazardous materials and wastes. For certain businesses we have divested, we have provided limited indemnifications for environmental contamination to the successor owners. We have also acquired and continue to acquire businesses and facilities to add to our operations. While we sometimes receive indemnification for pre-existing environmental contamination, the party providing the indemnification may not have sufficient resources to cover the cost of any required measures. Certain facilities of ours have been in operation for many years and we may be liable for remediation of any contamination at our current or former facilities; or at off-site locations where wastes have been sent for disposal, regardless of fault or whether we, our predecessors or others are responsible for such contamination. We have been responsible for remediation of contamination at some of our locations and, while such costs have not been material to date, the cost of remediation of any of these and any newly-discovered contamination cannot be quantified, and we cannot assure you that it will not materially affect our profits or cash flows. Changes in environmental laws, regulations or enforcement policies, including without limitation new or more stringentadditional regulations affecting disposal of hazardous substances and waste, greenhouse gas emissions or use of fossil fuels, could have a material adverse effect on our business, financial condition, or results of operations.

Labor disruptions at any of our major customers or at our own manufacturing facilities could adversely affect our results of operations and cash flow.
Many of our customers have unionized workforces and could experience labor disruptions such as work stoppages, slow-downs, and strikes. A labor disruption at one or more of our customers could interrupt production or sales by that customer and cause the customer to halt or limit orders for our products and services. Any such reduction in the demand for our products and services would adversely affect our net sales, results of operations, and cash flow.
In addition, approximately 12% of our own employees are represented by unions through various collective bargaining agreements. Three of our CBAs expire and will be renegotiated in 2015. It is likely that our unionized employees will seek an increase in wages and benefits at the expiration of these agreements, and we may be unable to negotiate new agreements without labor disruption or on terms favorable to us. In addition, labor organizing activities could occur at any of our facilities. If any labor disruption were to occur at our facilities, we could lose sales due to interruptions in production and could incur additional costs, which would adversely affect our net sales, results of operations, and cash flow.
Our operations are subject to seasonal fluctuations that may impact our cash flow.
Our net sales are generally lower in the first and fourth quarters primarily due toas a result of reduced activity in the building industry due to inclement weather. In addition, quarterly results may be affected by the timing of shipments of large customer orders. Therefore, our cash flow from operations may vary from quarter to quarter. If, as a result of any such fluctuation, our quarterly cash flows were significantly reduced, we may not be able to service our indebtedness or maintain covenant compliance. A default under any of our indebtedness could prevent us from borrowing additional funds, limit our ability to pay interest or principal and allow our senior secured lenders to enforce their liens against our assets securing our indebtedness to these senior secured lenders.

Economic, political, and other risks associated with foreign operations could adversely affect our financial results.results and cash flows.
Although the large majority of our business activity takes place in the United States, we derive a portion of our revenues and earnings from operations in other countries,Canada, China and Japan, and are subject to risks associated with doing business internationally. Our sales originating outside the United States represented approximately 10%4% of our consolidated net sales during the year ended December 31, 2014. We have facilities in Canada, England, and Germany.2017. We believe that our business activities outside of the United States involve a higher degree of risk than our domestic activities. The risksactivities, such as the possibility of doing business in foreign countries include deterioration of foreign economic conditions, uncertainty over the stability of the Eurozone, the potential for adverse changes in the local political climate, in diplomatic relations between foreign countries and the United States or in governmental policies,unfavorable circumstances arising from host country laws or regulations, terrorist activity that may cause social disruption, logistical and communications challenges, costs of complying with a variety of laws and regulations, difficulty in staffing and managing geographically diverse operations, deterioration of foreign economic conditions, currency rate fluctuations, foreign exchange restrictions, differing local business practices and cultural considerations, restrictions on imports and exports or sources of supply, and changes in dutiestariff and trade barriers and import or taxes. Adverse changes inexport licensing requirements. In addition, any of these riskslocal or global health issue or uncertain political climates, international hostilities, natural disasters, or any terrorist activities could adversely affect customer demand, our net sales, results of operations and cash flows.our ability to source and deliver products and services to our customers.

Disruptions toFuture terror attacks, war, natural disasters or other catastrophic events beyond our business or the business of our customers or supplierscontrol could adverselynegatively impact our operations and financial results.
Business disruptions, including increased costsTerror attacks, war, or other civil disturbances, natural disasters and other catastrophic events could lead to economic instability, decreased capacity to produce our products and decreased demand for interruptionsour products. From time to time, terrorist attacks worldwide have caused instability in global financial markets. Concerns over global climate changes and environmental sustainability over time may influence the Company's strategic direction, supply of energychain, or raw materials, resultingdelivery channels. Also, our facilities could be subject to damage from severe weather events such as hurricanes,fires, floods, blizzards, and from casualty events, such as firesearthquakes or material equipment breakdown, from acts of terrorism, from epidemicother natural or pandemic disease, or from other events such as required maintenance shutdowns, could cause interruptions to our businesses as well as the operations of our customers and suppliers.man-made disasters.  Such interruptions could have an adverse effect on our operations, cash flows and financial results.
The nature of our business exposes us to product liability, product warranty and other claims, and other legal proceedings.
We are involved in product liability, product warranty and other claims relating to the products we manufacture and distribute that, if adversely determined, could adversely affect our financial condition, operating results, and cash flows. In addition, we are exposed to potential claims arising from parties, such as customers, for which we may be contractually liable.distribute. Although we currently maintain what we believe to be suitable and adequate insurance in excess of our self-insured amounts, there can be no assurance that we will be able to maintain such insurance on acceptable terms or that such insurance will provide adequate protection against potential liabilities. Product liability claims can be expensive to defend and can divert the attention of management and other personnel for significant periods, regardless of the ultimate outcome. Claims of this nature could also

have a negative impact on customer confidence in our products and our Company. We cannot assure you that any current or future claims will not adversely affect our reputation, financial condition, operating results, and cash flows.

If weevents occur or indicators of impairment are requiredpresent that may cause the carrying value of long-lived and indefinite-lived assets to take additionalno longer be recoverable, to exceed the fair value of the asset, or may lead to a reduction in the fair value of the asset, significant non-cash impairment charges to earnings such charges couldmay be significant andtaken that have a material impact on our results of operations.
We review the carrying value of long-lived assets for impairment when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. We also test goodwill in each of our reporting units and intangible assets with indefinite lives for impairment annually in the fourth quarter or sooner at interim dates if events or changes in circumstances indicate that the carrying value of the asset may exceed fair value. In recentprior years, we have recorded significant non-cash impairment charges for goodwill and other intangible assets as a result of reductions in the estimated fair values of certain businesses. Should the markets for our products deteriorate or should we decide to invest capital differently than as expected, or should other cash flow assumptions change, itIt is possible that we will be required to record additional noncashnon-cash impairment charges to our earnings in the future, which could be significant and have a material impact on our results of operations. Refer to “Critical Accounting Estimates” within Item 7 of this Form 10-K for more detail of how our financial statements can be affected by asset impairment.

The expiration, elimination or reduction of solar rebates, credits and incentives may adversely impact our business.
A variety of federal, state and local government agencies provide incentives to promote electricity generation from renewable sources such as solar power. These incentives are in the form of rebates, tax credits and other financial incentives which help to motivate end users, distributors, system integrators and others to install solar powered generating systems. Any changes to reduce, shorten or eliminate the scope and availability of these incentive programs could materially impact the demand for our related products, our financial condition and results of operations.

Item 2.Properties
Our principal executive office and headquarters is located in Buffalo, New York, in a leased facility. As of December 31, 2014,2017, we operated 3534 domestic facilities in the U.S., five in Canada, and two in Europe8 foreign facilities, of which 2729 were leased and 1513 were owned. We believe the facilities we operate and their equipment are effectively utilized, well maintained, in good condition, and will be able to accommodate our capacity needs to meet current levels of demand. Our broad North American and European network is well maintained and ourAsian manufacturing sites are located to optimize customer service, market requirements, distribution capability and freight costs. We continuously review

our anticipated requirements for facilities and, on the basis of that review, may from time to time acquire additional facilities and/or dispose of existing facilities. Most recently, our operational excellence initiatives and portfolio changes have enabled us to reduce, and may further reduce in the future, the number of facilities necessary to meet our customer needs.

The decrease in sales of $827.6 million for 2013. The increase was the result of divestitures related to the Company's portfolio management activities during 2016 along with a 3.2%slight decline in net sales volumes in our Industrial and Infrastructure segment. During 2016, the Company sold its European industrial manufacturing business to a third party and exited both the European residential solar racking business and the Company's U.S. bar grating product line. These divestitures resulted in a decrease in revenues of $81.6 million from the prior year. Largely offsetting these decreases were increased net sales volumes from both our Residential Products and Renewable Energy and Conservation Segments, including contributions from our recent acquisitions of Nexus in October 2016 and Package Concierge in February 2017, respectively. The above results include a net increase in volume of 2.3% as well as a 0.7%modest 1.5% increase in pricing to customers, and 0.3% increase due to sales generated by an acquisition completed in September 2013.customers.

The increase from prior year was primarily the result of a 9.5%4.0% net increase in volume along with a 0.7% increase due to$5.7 million of sales generated by anfrom the acquisition completed in 2013, slightly offset byof Package Concierge and a 0.5% decrease3.0% increase in pricing to customers. The most significant contributorhigher volume

was due to the increased sales was highera strong demand for ourbuilding products in the repair and remodel and new housing construction markets and growing demand for the Company’s centralized postalmail systems and parcel storage products. As postal authorities strive to convert door-to-door deliveries to centralized deliveries, sales of our cluster unit mail boxes have benefited. This segment also benefited from modestly higher sales of our roofing-related ventilation and rain dispersion products. The lower selling prices were primarily the result of meeting selective competitive situations.electronic package solutions.
Net sales in our Industrial and Infrastructure Products segment decreased 0.8%27.5%, or $3.3$81.1 million, to $430.2$214.0 million in 20142017 compared to $433.5$295.0 million in 2013.2016. The decrease in net sales was the combined result of the Company's exit from its U.S. bar grating product line and the divestiture of our European industrial manufacturing business, along with a 2.5%3.0% decrease in volume partially offset byas compared to the prior year. Excluding the impact of the divestitures, a 1.7% increasedecrease in pricing to customers. Lower demand for our transportation infrastructure products, includingwhich include components for bridges and elevated highways, accounted forfurther contributed to the overall segment revenue decline due to continued delay in infrastructure projects. We expect this decline to be temporary as evidenced by an increase in segment backlog during the current year. Partially offsetting the above decrease was increased volume decrease. Demand in this market is highly dependent on governmental funding and transportation projectsour industrial products as new products in these businesses continue to be negatively impactedgain traction.
Net sales in our Renewable Energy and Conservation segment increased 8.6%, or $24.3 million, to $306.4 million in 2017 compared to $282.0 million in 2016. The increase in 2017 was due to sales generated from the acquisition of Nexus in October 2016 along with increased volume in our domestic markets, partially offset by the uncertainty in government funding. The modest increase in pricing offered to customers wasexit of the result of covering raw material inflation. Company's small European residential solar racking business.
Despite the increase inOur consolidated net sales, our gross margin decreased to 16.2%24.0% for 20142017 compared to 19.1%24.3% for 2013. Contributing2016. The decline was primarily the result of a less favorable alignment of material costs to customer selling prices. Largely offsetting this less favorable alignment were benefits from portfolio management actions and the Company's 80/20 restructuring initiatives taken during 2016. Furthermore, the related costs associated with those actions decreased by $9.0 million as compared to the lower gross marginprior year. In 2016, the Company sold or exited less profitable businesses or products lines in order to enable the Company to re-allocate leadership, time, capital and resources to the platforms and businesses with the highest potential revenue and margins. In addition, other portfolio management actions and restructuring activities were competitive pressures on pricingtaken resulting from our 80/20 initiatives and increasing raw material costs. We also incurred additional costs to increase our manufacturing capacity this year in our Residential Products segment, and initial

Selling, general, and administrative ("SG&A") expenses decreased by $17.7 million, or 11.0%, to $143.4 million for 2017 from $161.1 million for 2016. The $17.7 million decrease was due to a $15.3 million decrease in performance-based compensation expenses, a combination of products withthe lower marginsprice of the Company's shares as compared to the prior year further contributed toand lower achievement under the margin compression in our Industrial and Infrastructure Products segment.Company's performance base compensation programs, along with a reduction of expenses as a result of the Company's 2016 divestitures.

Selling, general,acquisitions of Nexus and administrative (SG&A) expenses decreased by $11.0 million, or 9.7%, to $102.5 million for 2014 from $113.5 million for 2013. The $11.0 million decrease was largely the result of a $8.1 million decrease in variable performance based compensation as compared to 2013, plus a $1.4 million reduction in contigent consideration (or "earn-out") payable to the seller of a business acquired by the Company in 2013. The payable is adjusted on a quarterly basis through the Company's Statement of Operations based on the acquired business's projected EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization) through September 30, 2015.Package Concierge.

During 2014,In 2017, we recognized intangible asset impairment charges of $108.0$0.2 million. The related to indefinite-lived trademarks in our Renewable Energy and Conservation segment due to a realignment of businesses within this segment. During 2016, we recognized intangible asset impairment charges stemmedof $10.2 million. These charges primarily resulted from the decision in the fourth quarter of 2016 to discontinue the Company's U.S. bar grating product line and its European residential solar racking business which resulted in lower cash flows and estimated fair values of certain reporting units. The largest portion of the impairment was $92.5$8.0 million related to indefinite-lived intangibles in our Industrial and Infrastructure Products segment.

Interest expense decreased $8.1$0.6 million to $14.4$14.0 million for 20142017 from $22.5$14.6 million for 2013. The significant decrease in expense resulted from the redemption of the $204.0 million of the 8% Notes in the first quarter of 2013. In connection with this transaction, the Company recorded a charge of approximately $7.2 million, which included $3.7 million for the prepayment premium paid to holders of the 8% Notes, $2.2 million to write-off deferred financing fees2016. During 2017 and $1.3 million for the unamortized original issue discount related to the 8% Notes.

Due to this new legislation, a net benefit of $12.5 million was recorded in 2017, the result of a $16.2 million benefit primarily from the re-measurement of our net U.S. deferred tax liabilities at the lower corporate tax rate partially offset by an expense of $3.7 million related to foreign earnings.
The difference between the Company’s recorded benefitcharge for 20142016 and the benefitexpense that would result from applying the U.S. statutory rate of 35% is due to deductible permanent differences and favorable discrete items partially offset by state taxes.

Consolidated net sales increaseddecreased by $37.5$32.9 million, or 4.7%3.2%, to $827.6 million$1.01 billion for 2013 from net sales of $790.1 million2016 compared to $1.04 billion for 2012.2015. The increase from the prior yeardecrease was primarily the result of $52.4 million or 6.6% of incremental sales generated by four acquisitions, three of which were completed in the latter part of the fourth quarter of 2012 and one completed in September 2013. Net sales from businesses operating in both periods decreased 1.9% or $14.9 million, the result of a 2.8%combined 13.0% decrease in volume, a 0.7% decrease in pricing to customers, and a reduction in sales of $26.3 million due to the divestiture of our European industrial manufacturing business in April 2016. These decreases were partially offset by a 0.9% increaseincremental sales generated from acquisitions in volume. The lower selling prices were primarilyour Renewable Energy and Conservation segment, which contains the resultresults of a declineRBI acquired in commodity costs for steelJune 2015 and meeting selective competitive situations.Nexus acquired in October 2016. Favorable currency fluctuations also contributed to the offset.
Net sales in our Residential Products segment increased 5.1%decreased 9.4%, or $19.0$44.7 million, to $394.1$430.9 million in 20132016 compared to $375.1$475.7 million in 2012.2015.

Net sales from businesses operating in both periods increased 2.3% or $8.5 million, the resultcompletion of a 2.9% increasediscrete two-year contract at the end of 2015. Favorable currency fluctuations of $8.1 million partially offset this decrease. A decline in volume partiallyof 0.9% for our other residential product offerings, including reduced sales to small volume customers under our 80/20 simplification initiatives, also contributed to the net decrease in revenues for the year. These decreases were slightly offset by 0.7% decreasea 1.0% increase in pricing to customers. The increase was largely due to the growing demand for our centralized mail and parcel storage solutions, designed for apartments and condominiums.
Net sales in our Industrial and Infrastructure Products segment increased 4.5%decreased 21.7%, or $18.5$81.7 million, to $433.5$295.0 million in 20132016 compared to $415.0$376.7 million in 2012.2015. The increase from prior year was primarily the result of $41.9 million or 10.1% of incremental sales generated by two acquisitions which were completed in the latter part of the fourth quarter of 2012. Net sales from businesses operating in both periods decreased 5.6% or $23.4 million, the result of a 4.6% decrease in pricing to customers and a 0.9% decrease in volume. The lower selling prices were primarily the result of a decline in commodity costs for steel and meeting selective competitive situations. While volumes increased in our domestic industrial products, the increase was more than offset by declines in volume in our European markets, the continued result of weak economic conditions in that region.
The increase in net sales was the principal factorcombined result of the April 2016 divestiture of our European industrial manufacturing business which previously contributed 7.0% of sales, as well as, lower shipment volume of 11.3%, and a 3.2% decrease in pricing offered to customers, as compared to the prior year. This segment was primarily impacted by a decline in demand for our industrial products generated from domestic energy-related end markets that have been depressed by reduced prices for oil and other commodities. Demand for our infrastructure products, including components for bridges and elevated highways, related to these projects was also lower as compared to the prior year. While a new infrastructure bill was passed in December 2015 authorizing U.S. federal funding for five years, the FAST Act, the matching state funding required to obtain the federal funds was not available in key states we serve.
Net sales in our Renewable Energy and Conservation segment increased 49.6%, or $93.5 million, to $282.0 million in 2016 compared to $188.5 million in 2015. The increase in 2016 was primarily due to the benefit of incremental revenues earned by

RBI in the current year as compared to the prior year in which RBI was acquired in June of 2015. Sales from the acquisition of Nexus in October 2016 also contributed to the increase in ourincrease.
Our consolidated gross margin increased to 19.1%24.3% for 20132016 compared to 18.9%18.0% for 2012. Also contributing to2015. Our consolidated gross profit also increased for the comparable period.
In our Residential Products segment, both gross profit and gross margin, in 2013 wasas a lower amountpercentage of restructuring and inventory charges in 2013sales, increased as compared to 2012 of $1.2 million and $2.2 million, respectively. The 2012 gross margin was impacted by costs to consolidate certain of our West Coast locations with similar products and market characteristics and was2015. This segment largely completed by early 2013. Partially offsetting the favorable comparison on restructuring costs was a less favorablebenefited from operational efficiencies, an improved alignment of material costs to customer selling prices forand contributions from our 80/20 initiatives to simplify our business processes and product lines. Also contributing to the margin increase were favorable currency fluctuations, as compared to the same period in the prior year.
Both gross profit and gross margin, as a percentage of sales, decreased as compared to the prior year within our Industrial and Infrastructure Products segment. The profit decrease was due to a significant decrease in sales volume in industrial products, the disposition of our European industrial manufacturing business in 2013,April 2016, decrease in pricing offered to customers, along with currency fluctuations. The margin decrease was partially offset by manufacturing efficiencies, savings from our company-wide 80/20 initiatives and better alignment of material costs to customer selling prices.
Within our Renewable Energy and Conservation segment, both gross profit and gross margin, as a percentage of sales, increased as compared to the resultprior year. The increase in gross profit largely resulted from the benefit of decliningincremental revenue earned in 2016 as compared to the prior year in which RBI was acquired in June 2015. The execution of operational efficiencies in the segment, including rising synergies from raw material costssourcing, freight management, and strategic make-versus-buy decisions also contributed to the increase in 2013 comparedgross margin. To a lesser extent, the acquisition of Nexus in October 2016 contributed to 2012 and competitive pressures on pricing.the increase in gross profit as well.
Selling, general, and administrative (SG&A)("SG&A") expenses increased by $8.8$27.7 million, or 8.4%20.8%, to $113.5$161.1 million for 20132016 from $104.7$133.4 million for 2012.2015. The $8.8$27.7 million increase included $6.2was the result of $15.8 million of incremental SG&A expense recorded year over year at RBI, acquired in June 2015, along with $1.9 million of SG&A expense fromexpenses recorded at Nexus, acquired businessesin October 2016, and an$10.5 million of higher performance-based compensation costs. The net benefit of a $6.8 million gain on the sale leaseback of one of our facilities recorded during 2015 largely offset by acquisition-related costs of $6.1 million recorded during 2015, also contributed to the increase year over year. The higher performance-based compensation costs are the result of improvements in variabletwo key performance based compensationmetrics. One metric is improved operating results which is measured by the Company's increased earnings per share and return on invested capital year over year. The other metric is the higher price of $2.0 million.the Company's shares which increased 64% during 2016. SG&A expenses as a percentage of net sales increased to 13.7%16.0% for 20132016 compared to 12.8% for 13.2% for 2012.2015.
During the third quarter of 2013,2016, we recognized intangible asset impairment charges of $23.2$10.2 million. These charges primarily resulted from the decision in the fourth quarter of 2016 to discontinue the Company's U.S. bar grating product line and its European residential solar racking business which resulted in lower cash flows and estimated fair values of certain reporting units. The largest portion of the impairment was $21.3$8.0 million related to indefinite-lived intangibles in our European-based business for which estimated fair values declined on lower projected cash flows. In 2012, due to changesIndustrial and Infrastructure Products segment, with the balance of the charges occurring in the estimated fair value of a certain reporting unit resulting from a decrease in sales projections, along with continued under-performance in the operations of that reporting unit,Renewable Energy and Conservation segment. In 2015, we recognized intangible asset impairment charges of $4.6 million.

Our Residential Products segment generated an operating margin of 8.9% during 201315.1% in 2016 compared to aan operating margin of 6.4%9.8% in 2015. Apart from the impact of the gain of $6.8 million on the sale leaseback of a facility during 2012. Excluding the impairment chargesfirst quarter of $1.02015, the increase to its income from operations of $11.6 million for 2013was primarily due to the benefits of operational efficiencies and $4.6 million for 2012,contributions from the Residential Products segment generated operating income80/20 simplification initiative, along with favorable effects of $36.0 million or 9.1% of sales in 2013currency fluctuations as compared to $28.5 million or 7.6% of2015. Partially offsetting these benefits were lower sales volumes primarily for 2012, an increase of $7.5 million, or 26.3%. While the segment had a modest increase resulting from acquisitions, the majority of the increase resulted from improved performance from our West Coast operations leading to lower restructuring and inventory charges in the 2013 period compared to the prior year. The 2012 period included costs to consolidate certain of our West Coast locations with similar products and market characteristics and was largely completed by early 2013.postal products.

Excluding the impact of a net change in intangible asset impairment charges of $22.2 million,and foreign currency fluctuations, this segment's decrease in income from operations was $10.3 million. Decreased sales volume resulted in the Industrial and Infrastructure segment generated operating income of $29.3 million or 6.8% of sales in 2013 compared to operating income of $34.6 million or 8.3% of sales for 2012, a decrease of $5.3 million, or 15.3%. Despite an increase in operating income due to acquisitions, this increase was more thanmargin decline, partially offset by a less favorablean improved alignment of material costs to customer selling prices.prices and benefits from cost reductions compared to the prior year.
CorporateThe Renewable Energy and Conservation segment generated an operating margin of 15.3% in 2016 compared to 6.7% in 2015. The increase in its income from operations was aided by contribution from incremental revenue for 2016 compared to the prior year in which RBI was acquired in June of 2015, along with $5.1 million of amortization expense incurred for RBI's backlog acquired in 2015. Additionally, the execution of operational efficiencies in the segment, including rising synergies from raw material sourcing, freight management, and strategic make-versus-buy decisions also contributed to the increase in income and margin for the current year.
Unallocated corporate expenses increased $2.4$10.0 million, or 13.0%37.9%, for 20132016 from $18.3$26.3 million for 20122015 to $20.7$36.3 million for 2013.2016. The increase from the prior year was primarily the result of an increase of $10.7 million in variable performance based compensation expense, the result of $2.6 million due to strongerimprovements in two key performance metrics. One metric is improved operating results which is measured by the Company's increased earnings per share and return on invested capital year over year. The other metric is the higher price of the Company's stock priceshares which increased 64% during 2016.
Other expense of $8.9 million in 2016 is primarily comprised of the value$8.8 million pre-tax loss on the sale of deferred salaryour European industrial manufacturing business. Other income of $3.4 million in 2015 is primarily comprised of net gains on derivative contracts for hedges on foreign currencies and previously earned bonuses.

Interest expense increased $3.9decreased $0.4 million or 21.0%, to $22.5$14.6 million for 20132016 from $18.6$15.0 million for 2012. The significant increase in expense resulted from the redemption of the $204.0 million of the 8% Notes in the first quarter of 2013. In connection with this transaction, the Company recorded a charge of approximately $7.2 million, which included $3.7 million for the prepayment premium paid to holders of the 8% Notes, $2.2 million to write-off deferred financing fees and $1.3 million for the unamortized original issue discount related to the 8% Notes. The $7.2 million charge was partially offset by lower interest expense of approximately $3.4 million resulting from the lower coupon rate on the $210.0 million 6.25% Notes issued in the first quarter of 2013 as compared to the 8% Notes.2015. During 2013 and 2012,2016, no amounts were outstanding under our revolving credit facility. In 2015, we borrowed funds under our revolving credit facility to help finance the acquisition of RBI in June 2015. These borrowings were paid in full prior to the end of 2015.
We recognized a provision for income taxes of $4.8$16.3 million, for 2013, an effective tax rate of -576.6%32.5%, for 2016 compared with a provision for income taxes of $9.5$13.6 million, an effective tax rate of 42.9%36.7%, for 2012.2015.

Outlook

During 2014,In 2018, we plan to drive sustainable organic growth through the acceleration of new product development initiatives, continue to implement operational improvement projects, and to seek value-added acquisitions in attractive end markets. On a comparative basis, excluding the $12.5 million, or $0.39 per share, one-time benefit from tax reform recorded in 2017, we expect one again to have generated increased profits at a higher rate of return with a more efficient use of capital in 2018.
The Company is providing its guidance for revenues and earnings for the full year 2018. Gibraltar expects 2018 consolidated revenues to exceed $1 billion, considering modest growth across our modest revenue growth was primarilyend markets and continued traction from innovative products. GAAP EPS for the result of demand for postal products that supported centralized mail delivery initiatives, partially offset set by lower sales of transportation infrastructure products.
We anticipate overall sales growth of low single digits in 2015 over 2014. We expect market conditionsfull year 2018 is expected to improve modestly for residential housing with industrialbe between $1.75 and transportation infrastructure markets being equivalent to 2014. Headwinds for 2015 revenue growth are expected from: the effects of lower commodity costs on the selling prices of certain industrial products$1.87 per diluted share, as well as affecting order rates for new projects in oil and gas markets; a continuing weak environment for broad-based price increases by which to offset inflationary costs; and the continuing uncertainty of federal government funding beyond May 31, 2015 for U.S. transportation projects.

We anticipate increased profitability in 2015 compared to $1.95 in 2017.
For the prior year. Aided by modestfirst quarter of 2018, the Company is expecting revenue growth, 2015 profit increases are expected from the incremental benefit of cost reduction actions completed in 2014 in overhead staffing, sales channel adjustments, and a facility closure along with 2015 productivity initiatives and other actions.

With modest margin expansion on full year consolidated sales growth, we expect earnings per share for 2015 in the range of $0.53$218 million to $0.63. This compares$225 million as a result of growth across all end markets and continued traction from innovative products. GAAP EPS for the first quarter 2018 is expected to loss of $2.63be between $0.20 and $0.25 per share for 2014, or an adjusted earnings per share of $0.47, which excludes the 2014 impairment loss of $3.09 perdiluted share.
Liquidity and Capital Resources
General
Our principal capital requirements are to fund our operations withoperations' working capital the purchase ofand capital improvements for our business and facilities, and to fund acquisitions. We will continue to invest in growth opportunities as appropriate while continuing to focusfocusing on working capital efficiency and profit improvement opportunities to minimize the cash invested to operate our business. We have successfully generated positive cash flows from operating activities during the past three years which have funded our capital requirements and assisted in the funding of our recent acquisitions as noted below in the “Cash Flows” section of Item 7 of this Annual Report on Form 10-K. We generated positive operating cash flows during these periods despite the continued challenging economic conditions our business faced. In the future, we expect to continue profitable growth and sustain strong working capital management which will generate positive operating cash flow.Flows.”
On October 11, 2011,December 9, 2015, we entered into the SeniorCompany's Fifth Amended and Restated Credit Agreement (the "Senior Credit Agreement") which includes a $2005-year, $300 million revolving credit facility and provides Gibraltarthe Company with access to capital and improved financial flexibility. As of December 31, 2014,2017, our liquidity of $209.0$511.1 million consisted of $110.6$222.3 million of cash and $98.4$288.8 million of availability under our revolving credit facility as compared to liquidity of $199.8$457.4 million as of December 31, 2013.2016. We believe that availability of funds under our Senior Credit Agreementthis liquidity, together with the cash expected to be generated from operations, should be sufficient to providefund working capital needs and simplification initiatives that likely will need cash to fund transitions and future growth. We continue to search for strategic acquisitions and larger acquisitions may require additional borrowings and/or the Company with the liquidity and capital resources necessary to supportissuance of our principal capital requirements during the next twelve months.common stock.
Our Senior Credit Agreement provides the Company with liquidity and capital resources for use by our U.S. operations. Historically, our foreign operations have generated cash flow from operations sufficient to invest in working capital and fund their capital improvements. As of December 31, 2014,2017, our foreign subsidiaries held $19.1$29.7 million of cash. We believeAs a result of the Tax Cuts and Jobs Act ("Tax Reform Act") signed into law on December 22, 2017, $25.7 million of cash held by our foreign subsidiaries provides our foreign operations withis expected to be repatriated to the necessary liquidity to meet future obligations and allows the foreign business units to reinvest in their operations. These cash resources could eventually be used to grow our business internationally through transactions similar to our 2012 acquisition of the Western Canadian bar grating business. RepatriationU.S. See Note 15 of this cashForm 10K for domestic purposes could result in significant tax consequences.consequences of repatriation of foreign cash.

Over the long-term, we expect that future obligations,investments, including strategic business opportunities such as acquisitions, may be financed through a number of sources, including internally available cash, availability under our revolving credit facility, new debt financing, the issuance of equity securities, or any combination of the above. PotentialAny potential acquisitions are evaluated based on our acquisition strategy, which includes the basisenhancement of our ability to enhance our existing products, operations, or capabilities, as well as provideexpanding our access to new products, markets, and customers, and improvethe improvement of shareholder value. Our 20122017 acquisition of Package Concierge and 2013 acquisitionsour 2016 acquisition of Nexus were funded by cash on hand.

As of December 31, 2014,2017, we had $98.4$288.8 million of availability under the Senior Credit Agreement andnet of outstanding letters of credit of $20.4$11.2 million. Only one financial covenant is contained within the Senior Credit Agreement, which requires us to maintain a fixed charge ratio (as defined in the agreement) of 1.25 to 1.00 or higher on a trailing four-quarter basis at the end of each quarter. As of December 31, 2014, we were in compliance with the minimum fixed charge coverage ratio covenant. Management expects to be in compliance with the fixed coverage ratio covenant throughout the next twelve months. No amounts were outstanding under our revolving credit facility during 2014as of December 31, 2017, or 2013.our predecessor credit facility as of December 31, 2016.
On January 31, 2013,In addition to our Senior Credit Agreement, the Company issued $210.0 million of 6.25% Senior Subordinated Notes (6.25% Notes)in January 2013 which are due February 1, 2021. In connection with the issuance of the 6.25% Notes, on January 16, 2013 the Company initiated a tender offer to purchase the outstanding $204.0 million of 8% Senior Subordinated Notes (8% Notes) due in 2015. Simultaneously with the closing of the sale of the 6.25% Notes on January 31, 2013, the Company purchased the tendered 8% Notes. The 8% Notes that were not tendered and purchased were called for redemption. In connection with the purchase and subsequent redemption, the Company satisfied and discharged its obligations under the 8% Notes as of January 31, 2013. The terms of the indenture for our 6.25% Notes do not fully prohibit us or our subsidiaries from incurring additional debt. The provisionsProvisions of the 6.25% Notes include, without limitation, restrictions on indebtedness, liens, and distributions from restricted subsidiaries, asset sales, affiliate transactions, dividends, and other restricted payments. Dividend payments are subject to annual limits of the greater of $0.25 per share or $25 million. The 6.25% Notes are redeemable at the option of the Company, in whole or in part, at any timeand interest is paid semiannually on or after February 1 2017, at the redemption price (as defined in the Senior Subordinated 6.25% Notes Indenture). The redemption prices will be 103.13%, and 101.56% of the principal amount thereof if the redemption occurs during the 12-month periods beginning FebruaryAugust 1 of the years 2017 and 2018, respectively, and 100% of the principal amount thereof on and after February 1, 2019, in each case plus accrued and unpaid interest to the applicable redemption date. In addition, prior to February 1, 2016, the Company may redeem up to 35% of the aggregate principal amount of the Notes with the net cash proceeds of certain equity offerings by the Company at a redemption price of 106.25% of the principal amount thereof, plus accrued and unpaid interest to the redemption date. In the event of a Change in Control (as defined in the Senior Subordinated 6.25% Notes Indenture), each holder of the 6.25% Notes may require the Company to repurchase all or a portion of such holder’s 6.25% Notes at a purchase price equal to 101% of the principal amount thereof.year.
Each of our significant domestic subsidiaries has guaranteed the obligations under the Senior Credit Agreement. The Senior Credit Agreement contains other provisions and events of default that are customary for similar agreements and may limit our ability to take various actions. The Senior Subordinated 6.25% Notes Indenture also contains provisions that limit additional borrowings based on the Company’s consolidated coverage ratio.
Off Balance Sheet Arrangements

Critical Accounting PoliciesEstimates
The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make decisions based upon estimates, assumptions, and factors it considers relevant to the circumstances. Such decisions include the selection of applicable principles and the use of judgment in their application, the results of which could differ from those anticipated.
A summary of the Company’s significant accounting policies are described in Note 1 of the Company’s consolidated financial statements included in Part II, Item 8, Financial Statements and Supplementary Data, of this Annual Report on Form 10-K.
Our most critical accounting policiesestimates include:
 
revenue recognition on contracts;

valuation of accounts receivable, which impacts selling, general, and administrative expense;receivable;
valuation of inventory, which impacts cost of sales and gross margin;inventory;
the allocation of the purchase price of acquisitions to the fair value of acquired assets and liabilities, which impacts our depreciation and amortization costs;liabilities;
the assessment of recoverability of depreciable and amortizable long-lived assets, which impacts the impairment of long-lived assets;
the assessment of recoverability of goodwill and other indefinite-lived intangible assets, which impacts the impairment of goodwillassets; and intangible assets;
accounting for income taxes and deferred tax assets and liabilities, which impact the provision for income taxes; and,
accounting for derivatives and hedging activities, which impact other income (expense), other comprehensive income.liabilities.
Management reviews these estimates, including the allowance for doubtful accounts and inventory reserves, on a regular basis and makes adjustments based on historical experience, current conditions, and future expectations. Management believes these estimates are reasonable, but actual results could differ from these estimates.

Revenue Recognition on Contracts
The vast majority of our sales agreements are for standard products and services, with revenue recognized on the accrual basis at the time of shipment of goods, transfer of title and customer acceptance, where required. However, revenue representing 28% and 26% of 2017 and 2016 consolidated net sales was accounted for using the percentage of completion, cost-to-cost method of accounting. This method of revenue recognition only pertains to the activities of RBI which was acquired on June 9, 2015.
Revenue on contracts using the percentage of completion method of accounting is recognized as work progresses toward completion as determined by the ratio of cumulative costs incurred to date to estimated total contract costs at completion, multiplied by the total contract revenue. Changes in estimates affecting sales, costs and profits are recognized in the period in which the change becomes known using the cumulative catch-up method of accounting, resulting in the cumulative effect of changes reflected in the period. Estimates are reviewed and updated quarterly for substantially all contracts. A significant change in an estimate on one or more contracts could have a material effect on our results of operations.
Contract costs include all direct costs related to contract performance. Selling and administrative expenses are charged to operations as incurred. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Because of inherent uncertainties in estimating costs, it is reasonably possible that changes in performance could result in revisions to cost and revenue, which are recognized in the period when the revisions are determined.

Valuation of Accounts Receivable
Our accounts receivable represent those amounts that have been billed to our customers but not yet collected.collected, as well as, costs in excess of billings which principally represent revenues recognized on contracts that were not billable as of the balance sheet date. As of December 31, 20142017 and 2013,2016, allowances for doubtful accounts of $4.3$6.4 million and $4.8$5.3 million were recorded, or approximately 4% and 5% of gross accounts receivable for both periods, respectively. We record an allowance for doubtful

accounts based on the portion of those accounts receivable that we believe are potentially uncollectible based on various factors, including experience, creditworthiness of customers, and current market and economic conditions. If the financial condition of customers were to deteriorate, resulting in impairment of their ability to make payments, additional allowances may be required. Changes in judgments on these factors could impact the timing of costs recognized.
Valuation of Inventories
We record our inventories at the lower of cost or market.net realizable value. We determine the cost basis of our inventory on a first-in, first-out basis using a standard cost methodology that approximates actual cost. On a regular basis, we calculate an estimated market value of our inventory, considered to be the prevailing selling price for the inventory less the cost to complete and sell the product. We compare the current carrying value of our inventory to the estimated market value to determine whether a reserve to value inventory at the lower of cost or marketnet realizable value is necessary. We recorded insignificant charges during the three year periodperiods ended December 31, 20142017, 2016, and 2015 to value our inventory at the lower of cost or market.net realizable value.
We regularly review inventory on hand and record provisions for excess, obsolete, and slow-moving inventory based on historical and current sales trends. We recorded reserves for excess, obsolete, and slow-moving inventory of $5.6$3.7 million and $3.8 million at both December 31, 20142017 and 2013,2016, respectively, or approximately 4% and 5% of gross inventories for 2014 and 2013, respectively.both periods. Changes in product demand and our customer base may affect the value of inventory on hand, which may require higher provisions for obsolete inventory.
In addition, as a result of the Company's 80/20 simplification initiative and portfolio management, we have identified low-volume, internally-produced products which have been or will be planned to be outsourced or discontinued. We have recorded

charges of $1.2 million and $3.6 million during the years ended December 31, 2017 and 2016, respectively, related to the write-down of inventory associated with either discontinued product lines or the reduction of manufactured goods offered within a product line. These assets were written down to their sale or scrap value, and were subsequently sold or disposed of. Further simplification initiatives in 2018 could be identified which may result in additional write-downs of inventory.
Accounting for Acquired Assets and Liabilities
When we acquire a business, we allocate the purchase price to the assets acquired and liabilities assumed in the transaction at their respective estimated fair values. We record any premium over the fair value of net assets acquired as goodwill. Significant judgment is necessary to determine the fair value of the purchase price. The allocation of the purchase price involves judgments and estimates both in characterizing the assets and in determining their fair value. The way we characterize the assets has important implications, as long-lived assets with definitive lives, for example, are depreciated or amortized, whereas goodwill is tested annually for impairment, as explained below.
With respect to determining the fair value of the purchase price, the most subjective estimates involve valuations of contingent consideration. We engage independent third party valuation specialists to assist in the determination of the fair value of contingent consideration. Key assumptions used to value the contingent consideration include future projections and discount rates.
With respect to determining the fair value of assets, the most subjective estimates involve valuations of long-lived assets, such as property, plant, and equipment as well as identified intangible assets. We use all available information to make these fair value determinations and engage independent valuation specialists to assist in the fair value determination of the acquired long-lived assets. The fair values of long-lived assets are determined using valuation techniques that use discounted cash flow methods, independent market appraisals, and other acceptable valuation techniques.
Due to the subjectivity inherent in determining the fair value of long-lived assets and the significant number of acquisitions we have completed, we believe the allocation of purchase price to acquired assets and liabilities is a critical accounting policy.

Impairment of Depreciable and Amortizable Long-lived Assets
We test long-lived assets for impairment when events or changes in circumstances indicate that the carrying amount of those assets may not be recoverable and exceeds their fair value, or on an annual basis at minimum. During our annual test, we perform a recoverability test by comparing the carrying amount of asset groups to future undiscounted cash flows expected to result from the use of the assets. The impairment loss would be measured as the amount by which the carrying amount of a long-lived asset exceeds its fair value as determined by discounted cash flow method, an independent market appraisal of the asset, or another acceptable valuation technique.

Table of Contents

In 2014,2017, after completing the recoverability test, onenone of the Company's reporting unit's future undiscounted cash flows waswere less than the carrying amount of its assets. Based on these results, we then conducted an analysis to measure the amount of the impairment loss by valuing the long-lived asset groups of the entity in the following order:
Receivables, inventory, and indefinite-lived intangibles
Property, plant, and equipment; and definite-lived intangibles
Goodwill
Upon calculating the fair value of the asset groups and comparing the fair value to the carrying value, the Company recorded impairment charges of $804,000 for property, plant, and equipment; and definite-lived intangibles. After taking the effects of these impairment charges into consideration, the Company determined that an impairment charge of $5,603,000 against goodwill was also necessary.
AsHowever, as a result of restructuring activities incurred by the Company, a net recovery forCompany's 80/20 simplification initiative and portfolio management, we have identified low-volume, internally-produced products which have been or are planned to be outsourced or discontinued. We have recorded charges or recoveries related to the impairment of property, plant and equipment associated with either discontinued product lines or the reduction of $0.5 millionmanufactured goods offered within a product line. These assets were written down to their sale or scrap value, and charges of $1.6 million were recorded duringsubsequently sold or disposed of. For the yearsyear ended December 31, 2014 and 2013, respectively.2017, we recorded a net recovery of $3.0 million on assets sold that were previously identified or impaired during the year ended December 31, 2016. We recorded charges of $3.9 million during the year ended December 31, 2016 related to these initiatives. Further simplification initiatives in 2018 could be identified which may result in additional impairments.
Goodwill and Other Indefinite-lived Intangible Asset Impairment Testing
Testing Methodology
Our goodwill and indefinite-lived intangible asset balances of $236.0$321.1 million and $42.7$45.1 million, respectively, which in aggregate represent 37% of total assets as of December 31, 2014, respectively,2017, are subject to impairment testing. We test goodwill and indefinite-lived intangible assets for impairment on an annual basis as of October 31 and at interim dates when indicators of impairment are present. Indicators of impairment could include a significant long-term adverse change in business climate, poor indicators of operating performance, or a sale or disposition of a significant portion of a reporting unit. As a result of the October 31, 2014 test, the Company recognized intangible asset impairment charges of $108.0 million for the year ended December 31, 2014.
We test goodwill for impairment at the reporting unit level. We identify our reporting units by assessing whether the components of our companyCompany constitute businesses for which discrete financial information is available and segment management regularly reviews the operating results of those components. During 2014, we identifiedWe have eleven reporting units, in total,ten of which ninehave goodwill.

During interim periods, we evaluate the potential for goodwill impairment using a qualitative assessment by considering factors such as, but not limited to, macroeconomic conditions, industry conditions, the competitive environment, changes in the market for our products and services, regulatory and political developments, entity specific factors such as strategy, changes in key personnel, and overall financial performance. If, after completing this assessment, it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value, we proceed to a quantitative impairment test. During the interim periods of 2017, we concluded that no indicators of impairment existed at interim dates and did not perform any interim impairment tests related to goodwill and indefinite-lived intangible assets.
The Company conducts its annual impairment test on all eleven reporting units hadas of October 31, during which we test goodwill atand other indefinite-lived intangible assets for impairment. On an annual basis, the beginning of the fiscal year.
Thequantitative goodwill impairment test consists of comparing the fair value of a reporting unit, as determined using two valuation methodologies described below, with itsthe carrying amount of the reporting unit including goodwill. If the carrying amount of the reporting unit exceeds the reporting unit’s fair value, the implied fair value of goodwill is compared to the carrying amount of goodwill. Anan impairment loss is recognized forin the amount by which the carrying amount of goodwill exceeds the implied fair value of goodwill.
Step one of the impairment test consists of comparingreporting unit exceeds the fair value of the reporting unit.
As a result of our quantitative testing, none of the reporting unitunits with goodwill as of our testing date had carrying values in excess of their fair values, nor were any of the reporting units at risk of impairment. There were no impairment charges against goodwill recorded during the years ended December 31, 2017 and 2015. In 2016, the Company discontinued its carrying amount including goodwill. European residential solar racking business which resulted in an impairment charge against goodwill of $0.9 million.
The fair value of each reporting unit is determined using a weighted average of the fair values calculated under two valuation techniques: an income approach and a market approach.
The income approach included a discounted cash flow model relying on significant assumptions consisting of revenue growth rates and profit margins based on internal forecasts, terminal value, and the weighted average cost of capital (WACC)("WACC") used to discount future cash flows. TheInternal forecasts of revenue growth, operating margins, and working capital needs of each reporting unit over the next five years were developed with consideration of macroeconomic factors, historical performance, and planned activities. We made a terminal value assumption that cash flows would grow 3.0% each year subsequent to 2022 based on our approximation of gross domestic product growth. To determine the WACC, is calculatedwe used a standard valuation method, the capital asset pricing model, based on readily available and current market data of peer companies considered market participants. Acknowledging the varying degrees of risk inherent in each reporting units’ ability to achieve long-term forecasted cash flows in applying the income approach, we applied a reporting unit-specific risk premium to the WACC of each reporting unit, the extent of which was determined based upon each reporting unit’s past operating performance and their relative ability to achieve the capital structureforecasted cash flows. The income approach is weighted at 67% when arriving at our concluded estimate of eleven market participants in the Company’s peer group.fair value of each reporting unit, as this technique uses a long-term approach that considers the expected operating profit of each reporting unit during periods where macroeconomic indicators are nearer historical averages. This weighting approach is consistent with prior years.

The market approach consisted of applying the Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA)("EBITDA") multiple to the forecasted EBITDA to be generated in the next two years.years in determining an estimated fair value for the reporting unit. The market approach also relied on the same significant assumptions used in the discounted cash flow model, consisting of revenue growth rates and profit margins based on internal forecasts and the EBITDA multiple selected from an analysis of peer companies. Similar to the WACC analysis, we assessed the risk of each reporting unit achieving its forecasts with consideration given to how each reporting unit has performed historically compared to forecasts.
Annual Impairment Testing
For the first nine months ended September 30, 2014, we concluded We also evaluated each reporting units' expected growth and historical performance relative to that no indicators of impairment existed at interim dates and did not perform any interim impairment tests related to goodwill and indefinite-lived intangible assets. The Company performed its annual impairment test as of October 31, 2014 during which we tested goodwill and other indefinite-lived intangible assets for impairment.

The 2014 annual impairment test examined all eleven reporting units and used the two valuation technique methodologies noted above (income and market approaches), and WACC calculation employed in prior years. The following table summarizes the WACC and EBITDA multiple ranges used during the annual goodwill impairment test performed during 2014:
Date of Impairment TestWACC
October 31, 201411.5% to 13.6%
EBITDA Multiple
October 31, 2014
2015 EBITDA forecast7.7 to 8.45
2014 EBITDA forecast10.3 to 11.05
Under the direction of Frank Heard, our new President and CEO, and in conjunction with our 2015 budgeting and forecasting process, we reevaluated our revenue projections including a continued slower economic recovery, and continued increased competition and pricing pressure. Of the eleven reporting units tested, we determined that five of the reporting units had carrying values in excess of their fair values due to decreased revenue projections affected by, but not limited to, slower economic conditionspeer companies and increased competition. The Company initiated step two of the goodwill impairment test for four of these reporting units, as one did not have goodwill as of our testing date. Step two involved calculating the implied fair value of goodwill by allocating the fair value of the reporting unitmade adjustments to the fair value of its assetsmultiples where the growth rates and liabilities other than goodwill, and comparing the implied fair value to the carrying amount of goodwill. The step two analysis relied on a number of significant assumptions to determine the fair value of the reporting units' net assets, including intangible assets. The fair value of intangible assets was determined using standard valuation methodologies including the “relief-from-royalty” method and “excess earnings” method. These methods primarily employed the use of future cash flows to determine the fair value of the applicable intangible assets. The future cash flows used to determine the fair values of these intangible assets were derived from step one of the goodwill impairment analysis as described above. The discount rate used in the valuation of intangible assets was derivedhistorical performance deviated from the WACC used in step one of the goodwill impairment analysis. Based on the analysis described above, wepeer companies. The market approach is weighted at 33% when arriving at our concluded the assumptions underlying step two of our impairment analysis were reasonable and appropriate. While any individual assumption could differ from those that we used, we believe the overall fair values of our reporting units are reasonable as the values are derived from a mix of reasonable assumptions. As a result of step two of the goodwill impairment test, the Company estimated that the implied fair value of goodwill for all four reporting units combined was less than its carrying value by $104,565,000, for which an impairment charge was recorded as of December 31, 2014. The Company also recorded impairment charges against goodwill of $21,040,000 and $4,328,000 as of December 31, 2013 and 2012, respectively.
The Company will continue to monitor impairment indicators and financial results in future periods. If cash flows change or if the market value of the Company’s stock decreases, there may be additional impairment charges. Impairment charges could be based on factors such as the Company’s stock price, forecasted cash flows, assumptions used, control premiums, or other variables.

(b)Other than the reporting units where we took impairment charges, no reporting units were deemed “at risk” which we define as a percentage of less the 10% by which estimated fair value exceeds carrying value.
The October 31, 2014 goodwill impairment test includes significant assumptions. We analyzed several macroeconomic indicators that impact each reporting unit to provide a reasonable estimate of revenue growth in future periods. We considered these forecasts in developing each reporting unit’s revenue growth rates over the next five years depending on the level of correlation between macroeconomic factors and net sales for each reporting unit. We concluded that this approach provided a reasonable estimate of long-term revenue growth and cash flows for each reporting unit.
Operating margins used to estimate future cash flows are based on margins generated during the past several years, adjusted for historical declines and slower recovery rates in both the residential housing markets and industrial and infrastructure markets, consolidation of facilities, cost reductions and restructuring activities enabling the business units to become more profitable as the economy continues to stabilize and recover. These actions led to increased costs and lower operating margins in the short term. Based on our understanding of these reporting units and the actions taken by management to restructure the businesses for improved growth and profitability, we concluded that the long-term cash flows forecasted for all of the Company’s reporting units were reasonable.
In addition to revenue growth and operating margin forecasts, the discounted cash flow model used to estimate the fair value of each reporting unit also uses assumptions for the amount of working capital needed to support each reporting unit. We forecasted stable to modest improvement in working capital management for future periods at each reporting unit based on past performance. Over the past years, we have improved and maintained our low levels of working capital management through lean initiatives, efficiency improvements, and facility consolidations. Our days of working capital ratio was 63 for the year ended December 31, 2014. We believe continued improvement in our ability to manage working capital will allow us to increase the cash flow generated from each reporting unit.
The terminal value of each reporting unit was based on a projected terminal year of forecasted cash flows in our discounted cash flow model. We made an assumption that cash flows would grow 3.0% each year thereafter in the North American markets, and 2.0% each year thereafter in the European markets served by the Company, based on our approximation of gross domestic product growth. This assumption was based on a third-party forecast of future economic growth over the long-term.

The discounted cash flow model uses the WACC to discount cash flows in the forecasted period and to discount the terminal value to present value. To determine the WACC, we used a standard valuation method, the capital asset pricing model, based on readily available and current market data of peer companies considered market participants. Acknowledging the risk inherent in each reporting units’ ability to achieve long-term forecasted cash flows, in applying the incomeweighting approach we increased the WACC of each reporting unit based upon each reporting unit’s past operating performance and their relative ability to achieve the forecasted cash flows.
As noted above, we used two commonly accepted valuation techniques to estimate a fair value for each reporting unit. The estimated fair value for each reporting unit was calculated using a weighted average between the calculated amounts determined under the income approach and the market approach. We weighted the income approach more heavily (67%) as the technique uses a long-term approach that considers the expected operating profit of each reporting unit during periods where macroeconomic indicators are nearer historical averages. We weighted the remaining (33%) using the market approach which values the reporting units using forecasted 2014 and 2015 EBITDA values based on current economic conditions and takes a more short-term approach. We believe the income approach considers the expected recovery in our end markets better than the market approach. Therefore, we concluded that the income approach more accurately estimated the fair value of the reporting units as it considers earnings potential during a longer term and does not use the short-term perspective used by the market approach. Accordingly, we concluded that the market participants who execute transactions to sell or buy a business in the current economic environment would place greater emphasis on the income approach.

The “Corporate” category includes unallocated corporate cash out flows. Unallocated corporate cash out flows include executive compensation and other administrative costs. Gibraltar has grown substantially through acquisitions and our strategy is to allow business unit management to operate the business units autonomous of corporate management. For example, each business unit has its own accounting, marketing, purchasing, information technology, and executive functions. As a result, we believe a market participant would not consider unallocated corporate cash flows when valuing each reporting unit and these cash flows have been properly excluded from the valuation of the reporting units.consistent with prior years.
Indefinite-Lived Intangibles
We test our indefinite-lived intangible assets for impairment by comparing the fair value of the indefinite-lived intangible asset, determined using a discounted cash flow model, with its carrying amount. Each reporting period, we perform an evaluation of the remaining useful life of our indefinite-lived intangible assets to determine whether events and circumstances continue to support an indefinite useful life. If an indefinite-lived intangible asset is subsequently determined to have a finite useful life, the asset is tested for impairment and then amortized prospectively over its estimated remaining useful life, and accounted for in the same manner as other intangible assets that are subject to amortization.

The assumptions used to determine the fair value of our indefinite-lived intangible assets are consistent with the assumptions employed in the determination of the fair values of our reporting units. An impairment loss would be recognized for the carrying amount in excess of its fair value. The fair values of

the impaired trademarks were determined using an income approach consisting of the relief-from-royalty method. TheDuring 2017, the Company recognized $0.2 million of impairment charges on our indefinite-lived intangible assets. In 2016, the Company incurred $7.8 million of impairment charges related to trademark intangible assets during the annual test for 2014Company's discontinued European residential solar racking business and U.S. bar grating product line, and an additional $1.2 million of $2,700,000. Asimpairment charges were recognized in 2016 as a result of the interim test for 2013, and theCompany's annual test for 2012, theimpairment test. The Company recognized total impairment charges of $2,454,000$9.0 million in 2016 related to indefinite-lived intangible assets, and $300,000, respectively.$4.9 million in 2015.
Accounting for Income Taxes and Deferred Tax Assets and Liabilities
Significant management judgment is required in determining our provision for income taxes, deferred tax assets and liabilities, and any valuation allowances. Our effective tax rates differ from the statutory rate due to the impact of permanent differences between income or loss reported for financial statement purposes and tax purposes, provisions for uncertain tax positions, state taxes, and income generated by international operations. Our effective tax rate was 3.5%19.2% for 2014. The difference between the Company’s recorded benefit for 2014 and the benefit that would result from applying the U.S. statutory rate of 35% is primarily attributable to the tax impact of the non-deductible goodwill and intangible asset impairments recognized during the year.year ended December 31, 2017. The effective tax rates were -576.6%,32.5% and 43.0%36.7% for the years ended December 20132016 and 2012,2015, respectively. Our future effective tax rates could be adversely affected by earnings being lower than anticipated in countries where we have lower statutory rates and vice versa. Changes in the valuation of our deferred tax assets or liabilities or changes in tax laws or interpretations thereof may also adversely affect our future effective tax rate. In addition, we are subject to the continuous examination of our income tax returns by the Internal Revenue Service and other tax authorities. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes.
Deferred tax assets and liabilities are determined based upon the differences between the financial statement and tax bases of assets and liabilities as measured by the enacted tax rates that will be in effect when these differences reverse. On December 22, 2017, the President of the United States signed into law the Tax Cuts and Jobs Act (the “Tax Reform Act”), which permanently reduces the U.S. corporate income tax rate from a maximum of 35% to a flat 21% rate, effective January 1, 2018. See Note 15 of the consolidated financial statements for the Company's income tax disclosures.
Valuation allowances are provided if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.
Regarding deferred income tax assets, we We maintained a valuation allowance of $0.4$2.2 million and $0.3$1.4 million as of December 31, 20142017 and 2013,2016, respectively, due to uncertainties related to our ability to realize these assets, primarily consisting of state net operating losses and other deferred tax assets. The valuation allowances are based on estimates of taxable income in each of the jurisdictions in which we operate and the period over which our deferred tax assets will be recoverable. If market conditions improve and future results of operations exceed our current expectations, our existing tax valuation allowances may be adjusted, such as the $2.3 million benefit recognized in the fourth quarter of 2013.adjusted. Alternatively, if market conditions deteriorate further or future operating results do not meet expectations, future assessments may result in a determination that some or all of the deferred tax assets are not realizable. As a result, we may need to establish additional tax valuation allowances for all or a portion of the gross deferred tax assets, which may have a material adverse effect on our results of operations and financial condition.
It is our policy to classify estimated interest and penalties due to tax authorities as income tax. Insignificant amounts of interest and penalties were recognized in the provision for income taxes for the years ended December 31, 2014, 20132017, 2016 and 2012.2015. Additionally, we classify tax credits as a reduction to income tax expense.

The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by tax authorities, based on the technical merits of each position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate resolution. As of December 31, 20142017 and 2013,2016, the liability for uncertainuncertainty in income tax positions was $1.4 million and $1.7 million, respectively.$3.5 million. Due to the high degree of uncertainty regarding the timing of potential future cash flows associated with these liabilities, we are unable to make a reasonably reliable estimate of the amount and period in which these liabilities might be paid.

Accounting for Derivative Financial Instruments and Hedging Activities

We record all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivative instruments that hedge forecasted transactions or the variability of cash flows related to a recognized asset or liability are designated as a cash flow hedge. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the hedged forecasted transactions in a cash flow hedge. Although certain of our derivative financial instruments do not qualify or are not accounted for under hedge accounting, we do not hold or issue derivative financial instruments for trading or speculative purposes.

Table of Contents

The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges of foreign exchange risk is recorded as a component of equity and is subsequently reclassified into earnings and reported in revenue in the period that the hedged forecasted transaction affects earnings. Any ineffective portion of the change in fair value of the derivative is recognized directly into earnings in other (income) expense. Our policy is to de-designate cash flow hedges at the time forecasted transactions are recognized as revenue on the statement of operations and report subsequent changes in fair value through the other (income) expense line on our statement of operations where the gain or loss due to movements in currency rates on the underlying asset or liability is revalued. If it becomes probable that the originally forecasted transaction will not occur, the gain or loss related to the hedge recorded within accumulated other comprehensive income is immediately recognized into other (income) expense.

Item 7A.Quantitative and Qualitative Disclosures about Market Risk
In the ordinary course of business, the Company is exposed to various market risk factors, including changes in general economic conditions, competition, and raw materials pricing and availability. In addition, the Company is exposed to other financial market risks, primarily related to its long-term debt and foreign operations.
Raw Material Pricing Risk
We are subject to market risk exposure related to volatility in the price of steel, aluminum and resins. A significant amount of our cost of sales relates to material costs. Our business is heavily dependent on the price and supply of our raw materials. Our various products are fabricated from steel, primarily hot-rolled and galvanized steel coils, plate and bars, produced by steel mills. We have other lesser volume products that are fabricated from aluminum coils, extrusions, and plastic resins. The commodity market, which includes the steel, aluminum, and resin industries, is highly cyclical in nature, and commodity costs have been volatile in recent years, and may become more volatile in the future. Commodity costs are influenced by numerous factors beyond our control, including general economic conditions, the availability of raw materials, competition, labor costs, freight and transportation costs, production costs, import duties and other trade restrictions.

The Company principally manages its exposures to the market fluctuations in the steel and resins industries through management of its core business activities. Although we have the ability to purchase steel from a number of suppliers, a production cutback by one or more of our current suppliers could create challenges in meeting delivery schedules to our customers. The prices we offer to our customers are also impacted by changes in commodity costs. We manage the alignment of the cost of our raw materials and prices offered to customers and attempt to pass changes to raw material costs through to our customers. To improve our management of commodity costs, we attempt to maintain lean inventory levels. Our investmentlevels not in ERP systems was made to increaseexcess of our effectiveness in this process.production requirements.

We have not entered into long-term contractscontractual commitments for the purchase of raw materials and have not maintained inventory levels in excess of our production requirements. However,however, from time to time, we may purchase raw materials in advance of commodity cost increases.

We rely on major suppliers for our supply of raw materials. During 2014,2017, we purchased our raw materials from domestic and foreign suppliers in an effort to purchase the lowest cost material as possible.

We cannot accurately calculate the pre-tax impact a one percent change in the commodity costs would have on our 20142017 operating results as the change in commodity costs would both impact the cost to purchase materials and the selling prices we offer our customers. The impact to our operating results would significantly depend on the competitive environment and the costs of other alternative building products, which could impact our ability to pass commodity costs to our customers.
To manage the risk associated with the fluctuations in the price of aluminum, the Company employs a combination of our normal operating activities, as discussed with regards to steel and resins above, and through the use of derivative financial instruments pursuant to the Company’s hedging practices and policies. We intend that the financial impact of these commodity hedging instruments primarily offset the corresponding changes in the fluctuations in the cost of aluminum being hedged. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s inventory and sales.

The Company entered into commodity options during 2014. The Company believes these instruments mitigate exposure in aluminum prices. Derivative accounting guidance requires that derivative instruments be recognized as either assets or liabilities at fair value. Gibraltar does not utilize the special election provided for under the accounting guidance for these commodity options and therefore, they are recorded at fair value through earnings as their fair value changes.

Although the Company’s commodity options do not qualify or are not accounted for under hedge accounting, we do not hold or issue derivative financial instruments for trading or other speculative purposes. We monitor our derivative positions against our commercial exposure.

Interest Rate Risk
To manage interest rate risk, Gibraltarthe Company uses both fixed and variable interest rate debt. Our fixed rate debt consists of the Company’s Senior Subordinated 6.25% Notes and was the only significant debt that remains outstanding at year end. We believe we limited our exposure to interest rate risk as a result of repaying substantially all variable rate debt and the long-term nature of our fixed rate debt. However, the Company will continue to monitor changes in its debt levels and access to capital ensuring interest rate risk is appropriately managed.
At December 31, 2014,2017, our fixed rate debt consisted primarily of $210.0 million of our 6.25% Notes. The Company’s $210.0 million of 6.25% Notes were issued in January 2013 and are due February 1, 2021.
Our variable rate debt consists primarily of the revolving credit facility under the Senior Credit Agreement, of which nowas amended and restated on December 9, 2015, and other debt. No amounts are outstanding on the revolving credit facility as of December 31, 2014, and other debt.2017. Borrowings under the revolving credit facility bear interest at a variable interest rate based upon the LIBOR plus an additional margin. A hypothetical 1% increase or decrease in interest rates would have changed the 20142017 interest expense by less than $0.1 million.

Foreign Exchange Risk
GibraltarThe Company has foreign exchange risk due to our international operations, primarily in Canada and Europe,Asia and through sales and purchases from foreign customers and vendors. Changes in the values of currencies of foreign countries affect our financial position and cash flows when translated into U.S. Dollars.dollars. The Company principally manages its exposures to many of these foreign exchange rate risks solely through management of its core business activities. We cannot accurately calculate the pre-tax impact that a 1%one percent change in the exchange rates of foreign currencies would have on our 20142017 operating results as the changes in exchange rates would impact the cost of materials, the U.SU.S. dollar revenue equivalents, and potentially the prices offered to our overseas customers.

The Company also manages the risks relating to currency fluctuations through the use of derivative financial instruments pursuant to the Company’s hedging practices and policies. The Company uses foreign currency derivatives including currency forward agreements and currency options to manage its exposure to fluctuations in the exchange rates. Currency forward agreements involve fixing the exchange rates for delivery of a specified amount of foreign currency on a specified date. The currency forward agreements are typically cash settled in U.S. dollars for their fair value at or close to their settlement date. The Company also uses currency option contracts under which the Company pays a premium for the right to sell a specified amount of a foreign currency prior to the maturity date of the option.

The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges of foreign exchange risk is recorded as a component of equity and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of the derivative, as well as amounts excluded from the assessment of hedge effectiveness, is recognized directly in earnings.

GIBRALTAR INDUSTRIES, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Principles of consolidation
The consolidated financial statements include the accounts of Gibraltar Industries, Inc. and subsidiaries (the Company)"Company"). All significant intercompany accounts and transactions have been eliminated in consolidation.
Use of estimates
The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.
Revenue recognition
RevenueThe majority of the Company's revenue is recognized when products are shipped or service is provided, the customer takes ownership and assumes the risk of loss, collection of the corresponding receivable is probable, persuasive evidence of an arrangement exists, and the sales price is fixed or determinable. Sales returns, allowances, and customer incentives, including rebates, are treated as reductions to sales and are provided for based on historical experience and current estimates.
Revenues representing 28.0% and 25.8% of sales for the years ended December 31, 2017 and 2016, respectively, were recognized under the percentage of completion accounting method as calculated by the cost-to-cost measurement method on contracts. The recognition of revenue under this method is utilized in the Renewable Energy and Conservation segment.
Revenue from contracts using the percentage of completion method of accounting is recognized as work progresses toward completion as determined by the ratio of cumulative costs incurred to date to estimated total contract costs at completion, multiplied by the total contract revenue. Changes in estimates affecting sales, costs and profits are recognized in the period in which the change becomes known using the cumulative catch-up method of accounting, resulting in the cumulative effect of changes reflected in the period. Estimates are reviewed and updated quarterly for all contracts. A significant change in an estimate on one or more contracts could have a material effect on our results of operations.
Contract costs include all direct costs related to contract performance. Selling and administrative expenses are charged to operations as incurred. Provisions for estimated losses on uncompleted contracts are recognized in the period in which such losses are determined. Because of inherent uncertainties in estimating costs, it is reasonably possible that changes in performance could result in revisions to cost and revenue, which are recognized in the period when the revisions are determined.
Cash and cash equivalents
Cash and cash equivalents include cash on hand, checking accounts, and allAll highly liquid investments with a maturity of three months or less.less are considered cash equivalents.
Accounts receivable and allowance for doubtful accounts
Accounts receivable are composed of trade and contract receivables recorded at either the invoiced amount or costs in excess of billings, are expected to be collected within one year, and do not bear interest. The allowance for doubtful accounts is the Company’s best estimate of the probable amount of uncollectible accounts in the Company’s existing accounts receivable. The Company determines the allowance based on a number of factors, including historical experience, credit worthiness of customers, and current market and economic conditions. The Company reviews the allowance for doubtful accounts on a regular basis. Account balances are charged against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The following table summarizes activity recorded within the allowance for doubtful accounts balances for the years ended December 31 (in thousands):

Table of Contents

Inventories are valued at the lower of cost, determined using the first-in, first-out method, or marketnet realizable value. Shipping and handling costs are recognized as a component of cost of sales. The Company records adjustments to reduce the cost of inventory to its net realizable value, if required, at the business unit level for estimated excess, obsolete, and slow-moving inventory. Factors influencing these adjustments include historical and current sales trends. Note 2 “Inventories” contains additional information on the Company’s inventory.
Property, plant, and equipment
Property, plant, and equipment are stated at cost and depreciated over their estimated useful lives using the straight-line method. Interest is capitalized in connection with construction of qualified assets. Expenditures that exceed an established dollar threshold and that extend the useful lives of assets are capitalized, while repair and maintenance costs are expensed as incurred. The estimated useful lives of land improvements, buildings, and building improvements are 15 to 40 years, while the estimated useful lives for machinery and equipment are 3 to 20 years. Accelerated depreciation methods are used for income tax purposes.
The table below sets forth the amount of interest capitalized and depreciation expense recognized during the years ended December 31 (in thousands):

Acquisition related assets and liabilities
Accounting for the acquisition of a business as a purchase transaction requires an allocation of the purchase price to the assets acquired and the liabilities assumed in the transaction at their respective estimated fair values. The most difficultcomplex estimations of individual fair values are those involving long-lived assets, such as property, plant, and equipment and intangible assets. The Company uses all available information to make these fair value determinations and, for major business acquisitions, engages independent valuation specialists to assist in the fair value determination of the acquired long-lived assets.
Goodwill and other intangible assets
The Company tests goodwill for impairment at the reporting unit level on an annual basis at October 31, or more frequently if an event occurs, or circumstances change, that indicate that the fair value of a reporting unit could be below its carrying amount.value. The reporting units are at the component level, or one level below the operating segment level. Goodwill is assigned to each reporting unit as of the date the reporting unit is acquired and based upon the expected synergies of the acquisition.
The Company may elect to perform a qualitative assessment that considers economic, industry and company-specific factors for some or all of our selected reporting units. If, after completing the assessment, it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying value, the Company proceeds to a quantitative test. The Company may also elect to perform a quantitative test instead of a qualitative test for any or all of the Company's reporting units.

The quantitative impairment test consists of comparing the fair value of a reporting unit, determined using two valuation techniques, withto its carrying amount including goodwill, and, ifvalue. If the carrying amountvalue of the reporting unit exceeds its fair value, comparinggoodwill is considered impaired, and a loss measured by the impliedexcess of the carrying value of the reporting unit over the fair value of goodwill with its carrying amount. An impairment loss wouldthe reporting unit must be recognized for the carrying amount of goodwill in excess of its implied fair value.recorded.
The Company also tests its indefinite-lived intangible assets for impairment on an annual basis as of October 31, or more frequently if an event occurs, or circumstances change, that indicate that the fair value of an indefinite-lived intangible asset could be below its carrying amount.value. The impairment test consists of comparing the fair value of the indefinite-lived intangible asset, determined using discounted cash flows on a relief-from-royalty basis, with its carrying amount. An impairment loss would be recognized for the carrying amount in excess of its fair value. Acquired identifiable intangible assets are recorded at estimated cost. Identifiable intangible assets with finite useful lives are amortized over their estimated useful lives.
Impairment of long-lived assets
Long-lived assets, including acquired identifiable intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of those assets may not be recoverable. TheIn specific situations, when the Company has selected individual assets to be sold or scrapped, the Company obtains market value data for those specific assets and measures and records the impairment loss based on such data. Otherwise, the Company uses undiscounted cash flows to determine whether impairment exists and measures any impairment loss by approximating fair value using acceptable valuation techniques, including discounted cash flow models and third-party appraisals. The Company recognized impairment charges related to intangible assets during the years ended December 31, 20142017, 2016 and 2013. In addition, the Company recognized a number2015. Several of these impairment charges related to restructuring plansexit activities during the three year period ended December 31, 20142017 as described in Note 1514 of the consolidated financial statements.

Deferred charges
Deferred charges associated with initial costs incurred to enter into new debt arrangements are included in other assetsas a component of long-term debt and are amortized as a part of interest expense over the terms of the associated debt agreements. Portions of these deferred financing charges were written off as a result of entering into amended and restated credit agreements and the redemption and reissuance of bonds as discussed in Note 7 of the consolidated financial statements.

Advertising
The Company expenses advertising costs as incurred. For the years ended December 31, 2014, 20132017, 2016 and 2012,2015, advertising costs were $4,000,000, $4,000,000$4.9 million, $5.1 million, and $3,600,000,$4.7 million, respectively.

Research and Development
The Company expenses research and development costs as incurred. For the years ended December 31, 2017, 2016 and 2015, research and development costs were $2.9 million, $2.2 million, and $0.9 million, respectively.
Foreign currency transactions and translation
The assets and liabilities of the Company’s foreign subsidiaries are translated into U.S. dollars at the rate of exchange in effect at the balance sheet date. Income and expense items are translated at the average exchange rates prevailing during the period.
Income taxes
The provision for income taxes is determined using the asset and liability approach. Under this approach, deferred income taxes represent the expected future tax consequences of temporary differences between the carrying amounts and tax basis of assets and liabilities. The Company records a valuation allowance to reduce deferred tax assets when uncertainty exists regarding their realization. On December 22, 2017, the President of the United States signed into law the Tax Cuts and Jobs Act (the “Tax Reform Act”). Further information on the impact of the Tax Reform Act is included in Note 15 of the consolidated financial statements.

Equity-based compensation
The Company measures the cost of equity-based compensation based on grant date fair value and recognizes the cost over the period in which the employee is required to provide service in exchange for the award.award reduced by forfeitures. Equity-based compensation consists of grants of stock options, deferred stock units, restricted stock, restricted stock units, and performance stock units. Equity-based compensation expense is included as a component of selling, general, and administrative expenses. The Company’s equity-based compensation plans are discussed in more detail in Note 1112 of the consolidated financial statements.

Derivatives and hedgingSale-Leaseback Transactions
The Company records all derivativesDuring the first quarter of 2015, in order to capitalize on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivative instruments that hedge a forecasted transaction or the variability of cash flows related to a recognized asset or liability are designated as a cash flow hedge. Hedge accounting generally provides matching the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the earnings effect of the hedged forecasted transactions in a cash flow hedge. Although certain of the Company's derivative financial instruments do not qualify or are not accounted for under hedge accounting, the Company does not hold or issue derivative financial instruments for trading or speculative purposes.

The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges of foreign exchange risk is recorded in other comprehensive income and is subsequently reclassified into earnings and reported in revenue in the period that the hedged forecasted transaction affects earnings. Any ineffective portion of the change in fair value of the derivative is recognized directly into earnings in other (income) expense. The Company's policy is to de-designate cash flow hedges at the time forecasted transactions are recognized as assets or liabilities on the balance sheet and report subsequent changes in fair value through the other (income) expense line on our statement of operations where the gain or loss due to movements in currency rates on the underlying asset or liability is revalued. If it becomes probable that the originally forecasted transaction will not occur, the gain or loss related to the hedge recorded within accumulated other comprehensive income is immediately recognized into net income.
Sale-Leaseback Transaction
In June 2014, the Company determined that it no longer required full use of the available space on one of itsfavorable real estate properties. Themarket conditions, the Company entered into a transaction to sell the propertyone of its real estate properties to an independent third party for $4,500,000, and lease-back a portion of it from the purchaser.$26.4 million. The Company leased back approximately 50% of the buildingentire property under a five year operating lease agreement. In accordance with the U.S. generally accepted accounting principles, the Company accounted for the

transaction as a sale-leaseback. The net present value of the Company's future minimum lease payments of $892,000$5.8 million were greaterless than the gain on sale of $829,000.$13.1 million. As such, the portion of the gain equal to the fair value of the future minimum lease payments was deferred and is being amortized on a straight-line basis over the five year lifeterm of the lease. The gain exceeding the fair value of the minimum lease payments amounted to $7.4 million and was recognized during the quarter ended March 31, 2015 as a component of selling, general, and administrative expenses. The minimum lease payment infor each of the first yearfive years is $202,000 and escalates at 3% over the remaining four years. $1.4 million.
These amounts have been included in the future minimum lease payments table in Note 1817 of the consolidated financial statements.

Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment
The standard eliminates the "Step 2" analysis to determine the amount of impairment realized when a reporting unit's carrying amount exceeds its fair value in its "Step 1" analysis of accounting for impairment of goodwill. The impairment charge would be the amount determined in "Step 1." The provisions of this standard are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for annual and interim goodwill impairment testing dates after January 1, 2017.
The Company has adopted this standard and it did not have any impact on the Company's consolidated financial statements.








Date of adoption: Q1 2017
ASU No. 2017-07
Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost
The standard requires an employer to recognize the service cost component of net periodic pension costs and net periodic postretirement benefit costs in the same line item(s) as other compensation costs from services rendered by pertinent employees during the period. Other components of net benefit cost are required to be presented separately from the service cost component and outside a subtotal of income from operations. The provisions of this standard are effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted as of the beginning of an annual period for which financial statements (interim or annual) have not been issued or made available for issuance.
The Company has adopted this standard and has applied it retrospectively for the presentation of the service cost component, as well as, other components of net periodic pension cost and net periodic postretirement benefit cost in our statement of operations. The adoption decreased selling, general, and administrative expense by $524,000 and $647,000 for the twelve months ended December 31, 2016 and 2015, respectively, and comparably increased other expense by the same amounts, respectively. This guidance did not have any impact on our balance sheet or our statement of cash flows.

Revenue from Contracts with Customers (Topic 606)
And All Related ASUs
The standard requires an entity to 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 standard also requires additional disclosures about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and assets recognized from costs incurred to obtain or fulfill a contract. The provisions of the standard, as well as all subsequently issued clarifications to the standard, are effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. The standard can be adopted using either a full retrospective or modified retrospective approach.
The Company currently believes the most significant impact of this standard upon adoption relates to the revenue recognition for certain custom fabricated products for which there is no alternative use and where the Company has written enforceable rights to payment for performance to date should the customer terminate the contract. These products are within the Company's Industrial and Infrastructure Products segment. Under this standard, the Company expects to recognize revenue on an over time basis on these custom fabricated products in the Industrial and Infrastructure Products segment which is a change from our current revenue recognition policy of point-in-time basis. The Company expects revenue recognition related to the remaining Industrial and Infrastructure Products segment, Residential Products segment and Renewable Energy and Conservation segment to remain substantially unchanged upon adoption of this standard. The Company has identified and implemented appropriate changes to the Company's business processes, systems and internal controls to support recognition and disclosure under this standard. The Company will use the modified retrospective transition method approach and apply it to open contracts as of January 1, 2018. Under this method, incremental disclosures will be provided to present each financial statement line item for 2018 under the prior standard. The Company estimates the cumulative effect of adoption to be approximately $750,000 increase to opening retained earnings, as of January 1, 2018.

ASU No. 2016-02
Leases (Topic 842)
The standard requires lessees to recognize most leases as assets and liabilities on the balance sheet, but record expenses on the statement of operations in a manner similar to current accounting. For lessors, the guidance modifies the classification criteria and accounting for sales-type and direct financing leases. The standard also requires additional disclosures about leasing arrangements and requires a modified retrospective transition approach for existing leases, whereby the standard will be applied to the earliest year presented. The provisions of the standard are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted.
The Company is currently evaluating the impact of this standard on the Company's consolidated financial statements and related disclosures, including the impact on the Company's current lease portfolio from both a lessor and lessee perspective. The adoption of this standard will primarily result in an increase in the assets and liabilities on the Company's consolidated balance sheet and related disclosures.

Goodwill is recognized net of accumulated impairment losses of $255,530,000 and $150,965,000$235.4 million as of December 31, 20142017 and 2013,2016, respectively. No goodwill impairment charges were recognized by the Company during 2017.
Annual Impairment Testing
The Company performed its annual goodwill impairment test as of October 31, 2014, 2013,2017, 2016, and 2012. During 20142015. The Company did not recognize any impairment charges during 2017, 2016, and 2012, the Company incurred impairment charges2015 as a result of the annual goodwill impairment test. However, subsequent to the annual goodwill impairment test as of October 31, annual tests. The2016, the Company discontinued its European residential solar racking business which resulted in an impairment charges recognized in 2013 resulted fromcharge against goodwill of $0.9millionwhich was recorded for the interim test performed during the third quarter. No additional impairment charges were incurred as of the annual test in 2013.year ended December 31, 2016.
During the October 31, 20142017 impairment test, the Company examinedconducted a quantitative analysis for all eleven reporting units identified for review.
Step one of the Company’s reporting units. The quantitative impairment test consists of comparing the fair value of a reporting unit with its carrying amountvalue including goodwill. The fair value of each reporting unit evaluated under the quantitative test was determined using two valuation techniques: an income approach and a market approach. Each valuation approach relies on significant assumptions including a weighted average cost of capital (WACC). The WACC is calculated("WACC") based upon the capital structure of market participants in the Company’s peer group. Other assumptions used to calculate fair value for each reporting unit includegroups, projected revenue growth, forecasted cash flows, and earnings multiples based on the market value of the Company and market participants within its peer group.groups.
The following table summarizesAs a result of our annual testing for 2017 and 2016, none of the WACC calculation ranges used during the annual goodwill impairment tests performed during 2014 and 2013:
Date of Impairment TestWACC
October 31, 201412.9% to 13.6%
October 31, 201311.1% to 12.7%
During our 2014 and 2012 annual goodwill impairment tests, we identified reporting units with goodwill as of our testing date had carrying values in excess of their fair value due to decreased revenue projections. Therefore, the Company initiated step two of the goodwill impairment test which

Table of Contents

involved calculating the implied fair value of goodwill by allocating the fair value of the reporting unit to the fair value of its assets and liabilities other than goodwill, calculating an implied fair value of goodwill, and comparing the implied fair value to the carrying amount of goodwill. As a result of step two of the annual goodwill impairment test, the Company estimated that the implied fair value of goodwill for the reporting units was less than their carrying values by $104,565,000 and $4,328,000 for the years ended December 31, 2014 and 2012, respectively, which have been recorded as impairment charges.values.
Interim Impairment Testing
We test goodwill and indefinite-lived intangible assets for impairment on an annual basis as of October 31 and at interim dates when indicators of impairment are present. During the third quarter of 2013, we significantly revised our forecast to reflect lower revenueIn 2017, 2016 and operating margin expectations for the Company in 2013. As a result, we concluded there was an indicator of impairment requiring an interim impairment test for four of our reporting units, two within the Residential Products segment and two within the Industrial and Infrastructure Products segment. In 2014 and 2012,2015, no indicators of impairment were identified as of interim dates; therefore, no interim tests were performed.

The 2013 interim impairment test used similar valuation methodology as used during the annual tests (income and market approaches), and WACC calculation employed in the interim test. The Company based the WACC on similar market participants used in the interim test. Other assumptions used in the multiples approach such as projected revenue growth and forecasted cash flows for the Company’s reporting units were also similar to those used during the interim test. A third party projection of peer companies’ earnings multiples, projected revenue growth, and forecasted cash flows were obtained for the analysis as well.
Of the four reporting units identified during the 2013 interim test, one of the reporting units in the Industrial and Infrastructure Products segment, and the Company’s sole business in Europe, had a carrying value in excess of the fair value due to decreased revenue projections, affected by recessionary economic conditions. Therefore, the Company initiated step two of the goodwill impairment test which involved calculating the implied fair value of goodwill by allocating the fair value of the reporting unit to the fair value of its assets and liabilities other than goodwill, calculating an implied fair value of goodwill, and comparing the implied fair value to the carrying amount of goodwill. As a result of step two of the goodwill impairment test, the Company estimated that the implied fair value of goodwill for the reporting unit was less than its carrying value by $21,040,000, for which an impairment charge was recorded as of September 30, 2013.

Foreign Pension
The Company has another unfunded supplemental pension plan at one of our European subsidiaries which provides defined pension benefits to certain employees upon retirement. The plan has been frozen and no additional participants will be added to the plan in the future. The projected benefit obligation at December 31, 2014 and 2013 is $410,000 and $441,000, respectively. A pre-tax accumulated other comprehensive loss retirement benefit liability adjustment of $113,000 and $73,000 has been recognized in 2014 and 2013, respectively, in the Company’s financial statements, for a net liability of $297,000 and $368,000 at December 31, 2014 and 2013, respectively.

Multiemployer Pension Plans
In addition, the Company contributes to a number of multiemployer defined benefit pension plans under the terms of collective-bargaining agreements that cover union-represented employees. The risks of participating in these multiemployer plans are different from single-employer plans in the following aspects:
a)Assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers.
b)If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers.
c)If the Company chooses to stop participating in some of the multiemployer plans, the Company may be required to pay those plans an amount based on the underfunded status of the plan, referred to as a withdrawal liability.
At December 31, 2017, the Company employed 2,022 people, of which approximately 11% were represented by unions through various collective bargaining agreements (CBAs). Three of the Company's six CBAs expired and were successfully renegotiated in 2016. None of our CBA's expire until April 30, 2018.
The Company’s participation in these plans for the year ended December 31, 20142017 is outlined in the table below. The “EIN/ Pension Plan Number” column provides the Employee Identification Number (EIN) and three-digit plan number, if applicable. Unless otherwise noted, the most recent Pension Protection Act (PPA) zone status available in 20142017 and 20132016 is for the plan’s year ended December 31, 20132016 and 2012,2015, respectively. The zone status is based on information that the Company received from the plans and is certified by the plans’ actuaries. Among other factors, plans in the red zone are generally less than 65% funded, plans in the yellow zone are less than 80% funded, and plans in the green zone are at least 80% funded.

At December 31, 2014, the Company employed 2,416 people, of which approximately 12% were represented by unions through various collective bargaining agreements (CBAs). Three of our CBAs expire and will be renegotiated in 2015. The multiemployer pension plans’ collective bargaining agreements expire April 15, 2015, April 30, 2015, and June 5, 2015, respectively. All of the funds have rehabilitation plans in place. Each plan with a rehabilitation plan requires minimum contributions from the Company. Given the status of these plans, it is reasonably possible that future contributions to the plans

will increase although the Company cannot reasonably estimate a possible range of increased contributions as of December 31, 2014.2017.

The Company did not contribute more than 5% of any fund’s total contributions in any of the three years in the period ended December 31, 2014.2017. The table below sets forth the contributions made by the Company to each multiemployer plan for the years ended December 31 (in thousands):

The Company has an unfunded postretirement healthcare plan which provides health insurance to certain employees and their spouses upon retirement. This plan has been frozen and no additional participants will be added to the plan in the future.

In October 2014 the Society of Actuaries issued new mortality tables and a mortality improvement scale which were applied when measuring the postretirement benefit obligation as of December 31, 2014. Because the new tables and improvement scale reflect today’s longer life expectancies, it resulted in an actuarial loss and an increase in our projected benefit obligation. As a result, we expect future net periodic postretirement benefit cost charged to expense to increase as a result of increases in the amortization of the actuarial loss.

If the total net (gain) or loss exceeds 10 percent of the greater of the accumulated postretirement benefit obligation or plan asset, this excess must be amortized over the average remaining service period of the active plan participants. If most of the plan participants are inactive, the amortization period is the expected future lifetime of inactive plan participants.

The remaining 25,000 units were awarded in February 2017 and April 2017. The number of these shares to be issued to the recipients will be determined based upon the ranking of the Company's total shareholder return ("TSR") over a three (3) year performance period ended December 31, 2020 compared to the TSR of companies in the S&P Small Cap Industrial Sector over the same three year period.
(3) The December 31, 2016 balance includes 321,714 units awarded in June 2015 that convert to shares based on RBI's gross profit performance relative to their targeted gross profit for 2016 and 2017. RBI achieved its targeted gross profit performance, and the Company will issue 321,714 shares to the recipients in 2018. The remaining 75,000 units were awarded in December 2015; of which 25,000 were forfeited in 2017 and 50,000 remain outstanding as of December 31, 2017. The number of these shares to be issued to the recipient will be determined based upon the ranking of the Company's total shareholder return over a three (3) year performance period ended December 31, 2018 compared to the total shareholder return of companies in the S&P Small Cap Industrial Sector over such period.
The fair value of the restricted shares, restricted stock units, and deferred stock units, as well as, the performance stock units ("PSUs") payable based on the Company's ROIC or targeted gross profit performance issued during the three years ended December 31, 2017 was based on the Company stock price at grant date of the award. The fair values of the PSU's payable based on TSR ranking issued during the three years ended December 31, 2017 were determined using a Monte Carlo simulation.

The account represents a share-based liability that is converted to and settled in cash at the trailing 200-day average closing price of the Company’s stock and payable to the participants upon retirement or a termination of their service to the Company. The matching portion vests only if the participant has reached their sixtieth (60th) birthday. If a participant terminates prior to age sixty (60), the match is forfeited. Upon termination, the account is converted to a cash account that accrues interest at 2% over the then current ten-year U.S. Treasury note rate. The account is then paid out in either one lump sum, or in five or ten equal annual cash installments at the participant’s election.

12. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES
The Company is exposed to certain risks arising from both its business operations and economic conditions. The primary risks that the Company manages through its derivative instruments are foreign currency exchange rate risk and commodity pricing risk. Accordingly, we have instituted hedging programs that are accounted for in accordance with Topic 815, “Derivatives and Hedging.”

Table of Contents

Our foreign currency hedging program is a cash flow hedge program designed to limit the exposure to variability in expected future cash flows. The Company uses foreign currency forward agreements and currency options, all of which mature within fourteen months, to manage its exposure to fluctuations in the foreign currency exchange rates. These contracts are not currently designated as hedging instruments in accordance with Topic 815, and therefore changes in fair value are recorded through earnings.

Our commodity price hedging program is designed to mitigate the risks associated with market fluctuations in the price of commodities. The Company uses commodity options, which are classified as economic hedges, to manage this risk. All economic hedges are recorded at fair value through earnings, as the Company does not qualify to use the hedge accounting designation as prescribed by Topic 815.

Although certain of our derivative financial instruments do not qualify or are not accounted for under hedge accounting, we do not hold or issue derivative financial instruments for trading or other speculative purposes. We monitor our derivative positions using techniques including market valuations and sensitivity analyses. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability. These changes in fair value are attributable to the earnings effect of the hedged forecasted transactions in a cash flow hedge.

We consider the classification of the underlying hedged item’s cash flows in determining the classification for the designated derivative instrument’s cash flows. We classify derivative instrument cash flows from hedges of changes in foreign currency as operating activities due to the nature of the hedged item. Cash flows from derivative instruments not designated under hedge accounting, such as our aluminum price options, are classified as investing activities.

Derivatives not designated as hedging instruments
To minimize commodity price exposure, the Company has commodity options with notional amounts of $10,440,000 at December 31, 2014. These derivative instruments mature at various times through January 2016.
To minimize foreign currency exposure, the Company has foreign currency options with notional amounts of $83,500,000 at December 31, 2014. These derivative instruments mature at various times through February 2016.

These commodity options and forward exchange options are recorded in the consolidated balance sheet at fair value and the resulting gains or losses are recorded to other income in the consolidated statement of operations. The losses (gains) recognized for the twelve months ended December 31, are as follows (in thousands):

13. FAIR VALUE MEASUREMENTS
FASB ASC Topic 820, “Fair Value Measurements and Disclosures,” defines fairFair value sets out a framework for measuring fair value, and requires certain disclosures about fair value measurements. A fair value measurement assumesis defined as the price that the transactionwould be received to sell an asset or paid to transfer a liability occurs in an orderly transaction between market participants at the principal market formeasurement date. Depending on the nature of the asset or liability. Fair value is defined based upon an exit price model. ASC 820 establishes a valuation hierarchy for disclosure of the inputsliability, various techniques and assumptions can be used to measureestimate fair value into three broad levels.value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement as follows:
Level 1 - UnadjustedQuoted prices in active markets for identical assets or liabilities.
Level 2 - Observable inputs other than quoted prices in active markets that are accessible to the reporting entity at the measurement date for identicalsimilar assets and liabilities.
Level 23 - Inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observableunobservable inputs for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of theliability.

The Company had no financial instrument.
Level 3 - Unobservable inputs for the assets or liability supported by little or no market activity. Level 3 inputs are based on the Company’s assumptions used to measure assets and liabilities at fair value.

As described in Note 4 of the consolidated financial statements, the Company acquired the assets of one business during the year ended December 31, 2013. The estimated fair values allocated to the assets acquired and liabilities assumed relied upon fair value measurements based in part on Level 3 inputs. The valuation techniques used to assign fair values to inventory, property, plant and equipment, and intangible assets included the cost approach, market approach, relief-from-royalty approach, and other income approaches. The valuation techniques relied on a number of inputs that included the cost and condition of the property, plant and equipment, forecasted net sales and incomes, and royalty rates. In addition, the Company has a contingent consideration liability related to the earn-out provision for the 2013 acquisition discussed in Note 4 that is recordedmeasured at fair value on a recurring basis each reporting period. A discounted cash flow analysis,at December 31, 2017 and 2016. The Company's only financial instrument for which takes into account a discount rate, forecasted EBITDA of the acquired businesscarrying value differs from its fair value is long-term debt. At December 31, 2017 and the Company’s estimate of the probability of the acquired business achieving the forecasted EBITDA is used to determine2016, the fair value of this liability at each reporting period until the liability will be settled in 2015.outstanding debt net of unamortized debt issuance costs was $213.8 million and $219.9 million, respectively, compared to its carrying value of $210.0 million and $209.6 million, respectively. The fair value of this liabilitythe Company's Senior Subordinated 6.25% Notes is determined usingclassified as Level 3 inputs. The2 within the fair value of this liability is sensitive primarily to changes in the forecasted EBITDA of the acquired business.
As described in Note 12 of the consolidated financial statements, the Company holds derivative foreign currency exchange forwards, foreign currency exchange optionshierarchy and commodity options. The fair values of foreign currency exchange contracts are determined through the use of cash flow models that utilize observablewas estimated based on quoted market data inputs to estimate fair value. These observable market data inputs include foreign exchange rate and credit spread curves. In addition, the Company received fair value estimates from the foreign currency contract counterparties to verify the reasonableness of the Company’s estimates.
The fair value of commodity options is determined through the use of cash flow models that utilize observable market data inputs to estimate fair value. These observable market data inputs include forward rates and implied volatility. In addition, the Company received fair value estimates from the commodity contract counterparty to verify the reasonableness of the Company’s estimates.prices adjusted for unamortized debt issuance costs.
The Company’s other financial instruments primarily consist of cash and cash equivalents, accounts receivable, notes receivable, and accounts payable, and long-term debt.payable.  The carrying values for our financial instruments approximate fair value with the exception, at times, of long-term debt. At December 31, 2014 and 2013, the carrying value of outstanding debt was $213,600,000 and $214,007,000, respectively.  The fair value of the Company’s Senior Subordinated 6.25% Notes was estimated based on quoted market prices.

Contingent consideration liability
As described in Note 4 of the consolidated financial statements, the Company acquired the assets of a business in 2013 for which a portion of the purchase consideration is based on an earn out provision. This liability resulting from this earn-out provision is based on the acquired business’s future EBITDA through 2015. A discounted cash flow analysis, incorporating a Monte Carlo simulation, was used to determine the fair value of a contingent consideration liability. The simulation used a triangular distribution of 500,000 trails and was performed incorporating assumptions such as project future incomes, upside potentials, low-end expectations, expected synergies to calculate the EBITDA. The calculated EBITDA was subsequently discounted at the pretax cost of debt to determine the fair value. The liability is revalued at each year end for actual EBITDA incurred during the earn-out period to determine the updated fair value.

The Company also applied fair value principles duringfor the goodwill impairment tests performed during 2014, 2013,2017, 2016, and 2012. Step one of the goodwill impairment test consisted of determining a fair value for each of the Company’s reporting units.2015. The fair value for the Company’s reporting units cannot be determined using readily available quoted Level 1 or Level 2 inputs that are observable or available from active markets. Therefore, the Company used two valuation models to estimate the fair values

of its reporting units, both of which primarily use Level 3 inputs. To estimate the fair values of reporting units, the Company uses significant estimates and judgmental factors. The key estimates and factors used in the valuation models include revenue growth rates and profit margins based on internal forecasts, terminal value, WACC, and earnings multiples. As a result of the goodwill impairment test performed during 2014, 2013, and 2012, the Company recognized goodwill impairment charges. See Note 56 of the consolidated financial statements for the results of the Company’s goodwill impairment tests.
Additionally, the Company's recent acquisition activity, as described in Note 5 of the consolidated financial statements, used Level 3 inputs to estimate fair values allocated to the assets acquired and liabilities assumed.

14. DISCONTINUED OPERATIONS

For certain divestiture transactions, the Company has agreed to indemnify the buyer for various liabilities that may arise after the disposal date, subject to limits of time and amount. The Company is a party to certain claims made under these indemnification provisions. For the years ended December 31, 2014, 2013, and 2012, management recorded a contingent liability for such provisions related to discontinued operations. Management does not believe that the outcome of such claims, or other claims, would significantly affect the Company’s financial condition or results of operations.
15. EXIT ACTIVITY COSTS AND ASSET IMPAIRMENTS
The Company focuses on beingcompleted the low-cost providerthird year of its five year planned transformation strategy formulated to transform its operations and improve its financial results over this five year period. This strategy includes an 80/20 simplification initiative which, in part, focuses the Company’s internal resources on further increasing the value provided to our customers. A result of this initiative was the identification of low-volume, low margin, internally-produced products by reducing operatingwhich have been or will be outsourced or discontinued. Portfolio management, another key part of the strategy and a natural adjunct to the 80/20 initiative, is another initiative in which management conducts strategic reviews of our current portfolio for future profitable growth and greater shareholder returns. This initiative has resulted in the sale and exiting of less profitable businesses or products lines in order to enable the Company to re-allocate leadership, time, capital and resources to the highest potential platforms and businesses. Exit activity costs and implementing leanasset impairment charges were incurred as a result of these initiatives.
In 2017, the 80/20 simplification initiative was initiated at additional business units as well as continued at those business units which commenced activity in 2016 and 2015. Correspondingly, the Company executed the portfolio management strategy in 2016, which had carryover effect in 2017. The portfolio management resulted in the execution of three transactions directly related to this strategy: the sale of its European industrial manufacturing initiatives, which havebusiness to a third party in part ledApril 2016, the exiting of its small European residential solar racking business and the exiting of its U.S. bar grating product line. Both the exit of the Company's small European residential solar racking business and the exit of the Company's U.S. bar grating product line commenced in the fourth quarter of 2016 and were essentially completed in 2017.
During 2017, asset impairment charges incurred by the Company were more than offset by a gain on sale of assets previously impaired in 2016 as a result of businesses and product lines discontinued. Specifically, asset sales related to the consolidationexit of both the Company's small European residential solar racking business and U.S. bar grating product line during 2017 resulted in a net gain. Asset impairments relate to the write-down of inventory and impairment of machinery, equipment and facilities associated with either businesses sold or exited, discontinued product lines or the reduction of manufactured goods offered within a product line. These assets were written down to their sale or scrap value, and product lines. were subsequently sold or disposed of.
The Company consolidated two facilities each year during 2014, 2013, and 2012, respectively, in this effort.
During this process, the Company hasalso incurred exit activity costs includingin 2017 which related to contract termination costs, severance costs, and other moving and closing costs. If future opportunities for cost savings are identified, other facility consolidationsThe above initiatives led to the closing and closings will be considered.

During 2014, theconsolidation of three facilities in 2017. The Company incurred a net changeclosed and consolidated seven facilities during 2016 and four facilities in 2015, which resulted in asset impairment charges of $455,000,and exit activity costs in both years. In addition, the net result ofCompany sold and leased back a gain on the sale of one of the consolidated facilities previously impairedfacility in 2013, partially offset by impairment charges for the other facility consolidated during 2014. 2015.

As noted above, the Company sold its European industrial manufacturing business to a third party on April 15, 2016, from its Industrial and Infrastructure Products segment. The pretax loss on the disposal was $8.8 million. The sale resulted in a net loss of $2.0 million on net proceeds of $8.3 million. This divestiture did not meet the criteria to be reported as a discontinued operation as it does not represent a strategic shift that has or will have a major effect on the Company’s operations. Therefore, prior period results of continuing operations have not been restated to exclude the impact of the divested business’s financial results. The pretax loss on disposal is presented within other expense (income) in the consolidated statement of operations. Neither the exit of the Company’s small European residential solar racking business nor its U.S. bar grating product line met the criteria to be reported as a discontinued operation. The costs related to exiting this business and product line are reflected in the above tables.
16.15. INCOME TAXES

On December 22, 2017, the President of the United States signed into law the Tax Cuts and Jobs Act (“Tax Reform Act”). The legislation significantly changes U.S. tax law by, among other things, lowering corporate income tax rates, implementing a territorial tax system and imposing a transition tax on deemed repatriated earnings of foreign subsidiaries. The Tax Reform Act permanently reduces the U.S. corporate income tax rate from a maximum of 35% to a flat 21% rate, effective January 1, 2018. As a result of the reduction in the U.S. corporate income tax rate from 35% to 21% under the Tax Reform Act, the Company revalued its ending U.S. net deferred tax liabilities at December 31, 2017 and recognized a provisional $16.2 million tax benefit in the Company’s consolidated statement of operations for the year ended December 31, 2017.


The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to reverse.

The Tax Reform Act provided for a one-time transition tax on post-1986 undistributed foreign subsidiary earnings and profits (“E&P”). The Company recognized a provisional $3.7 million of income tax expense as a result of the transition tax and related repatriation in the Company’s consolidated statement of operations for the year ended December 31, 2017.

While the Tax Reform Act provides for a territorial tax system, beginning in 2018, it includes two new U.S. tax base erosion provisions, the global intangible low-taxed income (“GILTI”) provisions and the base-erosion and anti-abuse tax (“BEAT”) provisions.

The GILTI provisions require the Company to include in its U.S. income tax return foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets. The Company expects that it will be subject to incremental U.S. tax on GILTI income beginning in 2018, due to expense allocations required by the U.S. foreign tax credit rules. The Company has elected to account for GILTI tax in the period in which it is incurred, and therefore has not provided any deferred tax impacts of GILTI in its consolidated financial statements for the year ended December 31, 2017.

The BEAT provisions in the Tax Reform Act eliminates the deduction of certain base-erosion payments made to related foreign corporations, and impose a minimum tax if greater than regular tax. The Company does not expect it will be subject to this tax.

On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Reform Act. The Company has recognized the provisional tax impacts related to the one-time transition tax, withholding tax and the revaluation of deferred tax assets and liabilities and included these amounts in its consolidated financial statements for the year ended December 31, 2017. As there is some uncertainty around the grandfathering provisions related to performance-based executive compensation, we have not included a provisional amount for deferred tax assets related to performance-based executive compensation as we believe that all of our plans are grandfathered. Our preliminary estimate of the one-time transition tax and the re-measurement of our deferred tax assets and liabilities is subject to the finalization of management’s analysis related to certain matters, such as developing interpretations of the provisions of the 2017 Tax Reform Act, changes to certain estimates and amounts related to the earnings and profits of certain subsidiaries and the filing of our tax returns, U.S. Treasury regulations, administrative interpretations or court decisions interpreting the 2017 Tax Reform Act may require further adjustments and changes in our estimates.

The final determination of the one-time transition tax and the re-measurement of our deferred assets and liabilities will be completed as additional information becomes available, but no later than one year from the enactment of the 2017 Tax Reform Act.

17.16. EARNINGS PER SHARE
Basic earnings per share is based on the weighted average number of common shares outstanding. Diluted earnings per share is based on the weighted average number of common shares outstanding, as well as dilutive potential common shares which in the Company’s case, include shares issuable under the equity compensation plans described in Note 1112 of the consolidated financial statements. The weighted average number of shares and conversions utilized in the calculation of diluted earnings per shareshares does not include potential anti-dilutive common shares aggregating 503,000, 762,000,468,000, 653,000 and 973,000643,000 at December 31, 2014, 2013,2017, 2016 and 2012,2015, respectively. The treasury stock method is used to calculate dilutive shares, which reduces the gross number of dilutive shares by the number of shares purchasable from the proceeds of the options assumed to be exercised and the unrecognized expense related to the restricted stock and restricted stock awards assumed to have vested.

Report of Independent Registered Public Accounting Firm

TheTo the Board of Directors and Shareholders of Gibraltar Industries, Inc.

Opinion on Internal Control over Financial Reporting
We have audited Gibraltar Industries, Inc.’s internal control over financial reporting as of December 31, 2014,2017, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (1992(2013 framework) (the COSO criteria). In our opinion, Gibraltar Industries, Inc.’s (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on the COSO criteria.

As indicated in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of Package Concierge, Inc., which is included in the 2017 consolidated financial statements of the Company and constituted 2% and 4% of total and net assets, respectively, as of December 31, 2017 and 1% and 1% of net sales and net income, respectively, for the year then ended. Our audit of internal control over financial reporting of the Company also did not include an evaluation of the internal control over financial reporting of Package Concierge, Inc.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2017 and 2016, and the related consolidated statement of operations, comprehensive income (loss), shareholders’ equity and cash flows for each of the three years in the period ended December 31, 2017, and the related notes and our report dated February 27, 2018 expressed an unqualified opinion thereon.

Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the company’sCompany’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 applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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

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

In our opinion, Gibraltar Industries, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2014, based on the COSO criteria.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Gibraltar Industries, Inc. as of December 31, 2014 and 2013, and the related consolidated statement of operations, comprehensive income, shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2014 of Gibraltar Industries, Inc. and our report dated February 24, 2015 expressed an unqualified opinion thereon.
