(the &#8220;Registrant&#8221;) filed a Registration Statement with a reoffer prospectus in Part I thereof under the Securities Act of 1933, as amended (the &#8220;Securities Act&#8221;) on Form S-8 (Registration No.&#160;333-211347) registering 99,204 shares of the Registrant&#8217;s common stock $0.01 par value, for issuance under the Registrant&#8217;s 2016 Stock Plan for Non-Employee Directors. Pursuant to General Instruction E of Form S-8, this Registration Statement incorporates by reference the contents of our Registration Statement on Form S-8 (Registration No. 333-211347), except as otherwise set forth herein.</font></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">This Registration Statement includes a reoffer prospectus in Part I (the &#8220;Revised Reoffer Prospectus&#8221;), which has been revised to update the reoffer prospectus that was filed with the Registrant&#8217;s Form S-8 Registration Statement No.&#160;333-211347. The Revised Reoffer Prospectus has been prepared in accordance with General Instruction C of Form S-8 and the requirements of Part I of Form S-3, and may be used for reoffers of shares of common stock (acquired or to be acquired pursuant to awards granted under the Plan) that are defined as &#8220;control securities&#8221; or &#8220;restricted securities&#8221; under General Instruction C of Form S-8.</font></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The names of persons selling shares under the Revised Reoffer Prospectus and the amount of such shares are set forth below under the caption &#8220;Selling Stockholders&#8221; to the extent we presently have such information. However, other affiliate selling stockholders may elect to sell shares under the Revised Reoffer Prospectus as they receive them from time to time in the future in which case, as their names and amounts of shares to be reoffered become known, we will supplement the Revised Reoffer Prospectus with that information. In addition, as permitted by General Instruction C of Form S-8, certain non-affiliates holding less than the lesser of 1,000 shares or 1% of our common stock issuable under the Plan may resell restricted securities issued under the Plan up to that amount under the Revised Reoffer Prospectus without being named therein. Any securities covered by the Revised Reoffer Prospectus which qualify for sale pursuant to Rule&#160;144 may be sold under Rule&#160;144 rather than pursuant to the Revised Reoffer Prospectus.</font></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div><br></div><div><div style="line-height:120%;text-align:center;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">4</font></div></div><hr style="page-break-after:always"><div><a name="s7A82E14B2F37A9C29008C6E2DCCE35C5"></a></div><div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div></div><div><br></div><div style="line-height:120%;text-align:center;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS</font></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The information in this reoffer prospectus and the documents incorporated by reference herein, other than historical statements, contains &#8220;forward-looking statements&#8221; within the meaning of the Private Securities Litigation Reform Act of 1995 that are based, in whole or in part, on current expectations, estimates, forecasts, and projections about the Company&#8217;s business, and management&#8217;s beliefs about future operations, results, and financial position. These forward-looking statements can generally be identified by the use of forward-looking terminology, including the terms &#8220;believes,&#8221; &#8220;estimates,&#8221; &#8220;anticipates,&#8221; &#8220;expects,&#8221; &#8220;seeks,&#8221; &#8220;projects,&#8221; &#8220;intends,&#8221; &#8220;plans,&#8221; &#8220;may,&#8221; &#8220;will&#8221; or &#8220;should&#8221; or, in each case, their negative or other variations or comparable terminology. These forward-looking statements include all matters that are not historical facts. They include statements regarding our intentions, beliefs or current expectations concerning, among other things, our results of operations, financial condition, liquidity, prospects, growth, competition, strategies and the industry in which we operate.</font></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">By their nature, forward-looking statements involve risks, uncertainties and assumptions because they relate to events and depend on circumstances that may or may not occur in the future. We believe that these risks and uncertainties include, but are not limited to, those described in the &#8220;Risk Factors&#8221; section of this reoffer prospectus below and in the forward-looking statements and cautionary statements contained in the documents we incorporate by reference in this reoffer prospectus. Those factors should not be construed as exhaustive and should be read together with the other cautionary statements in &#8220;Risk Factors&#8221;.</font></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Although we base these forward-looking statements on assumptions that we believe are reasonable when made, we caution you that forward-looking statements are not guarantees of future performance and that our actual results of operations, financial condition and liquidity and the development of the industry in which we operate may differ materially from those made in or suggested by the forward-looking statements contained herein. In addition, even if our results of operations, financial condition and liquidity and the development of the industry in which we operate are consistent with the forward-looking statements contained in this reoffer prospectus, those results or developments may not be indicative of results or developments in subsequent periods.</font></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Given these risks, uncertainties and assumptions, you are cautioned not to place undue reliance on these forward-looking statements. Any forward-looking statements that we make herein speak only as of the date of those statements, and we undertake no obligation to update those statements or to publicly announce the results of any revisions to any of those statements to reflect future events or developments. Comparisons of results for current and any prior periods are not intended to express any future trends or indications of future performance, unless expressed as such, and should only be viewed as historical data.</font></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">You should read this reoffer prospectus in its entirety, together with the information we incorporate by reference into this prospectus, with the understanding that actual results in the future may be materially different from what we presently expect. We will not update these forward-looking statements, even if our situation or expectations change in the future.</font></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">You should rely only on the information contained or incorporated by reference in this document.

If any of the following risks actually occur, our business, financial condition and/or operating results could be materially adversely affected.</font></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Macroeconomic factors outside of our control may adversely affect our business, our industry, and the businesses and industries of many of our customer and suppliers.</font></div><div style="line-height:120%;padding-top:8px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Macroeconomic factors have a significant impact on our business, including our ability to generate profitable margins, customer demand and the availability of credit and other capital. Our operations are subject to the effects of domestic and international economic conditions including government monetary and trade policies, as well as, the relative debt levels of the U.S. and the other countries which form the market for our products. The changing costs of energy, in particular the depressed price of oil plus other commodities, has, and may continue to, negatively impact demand for our expanded metal products. In addition, the recent fluctuation of the U.S. dollar impacts the prices we charge and costs we incur to export and import products. We are unable to predict the impact on our business of changes in domestic and international economic conditions. The construction market appears to have stabilized. However, as discussed in this and prior reports, the markets in which we operate have been challenging over the past few years 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 deteriorate, which could result in a corresponding decrease in demand for our products and negatively impact our results of operations and financial condition.</font></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Our amount of leverage 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.</font></div><div style="line-height:120%;padding-top:8px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We had total indebtedness of $209.8 million as of March&#160;31, 2017, of which $209.4 million is long-term debt. Our current level of indebtedness and the debt we may need to incur in the future to fund strategic acquisitions, investments or for other purposes could have significant consequences to our business, including the following:</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:72px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:10pt;padding-left:48px;"><font style="font-family:inherit;font-size:10pt;">&#8226;</font></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Our interest expense could increase if interest rates increase because the loans under our Senior Credit Agreement bear interest at a floating rate.

A covenant violation would require a waiver from our lenders, which could result in incurring additional financing fees that would be costly and adversely affect our profitability and cash flows.

Under this method, we recognize revenue 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 estimated contract revenue, less cumulative revenue recognized in prior periods. Changes in these required estimates could have a material adverse effect on sales and profits. Any adjustments are recognized in the period in which the change becomes known using the cumulative catch-up method of accounting. For contracts with anticipated losses at completion, we establish a provision for the entire amount of the estimated remaining loss and charge it against income in the period in which the loss becomes known. Amounts representing performance incentives, penalties, contract claims and the impacts of scope change negotiations are considered in estimating revenues, costs and profits when they can be reliably estimated and realization is considered probable. Due to the substantial judgmental estimates involved with this process, our actual results could differ materially or could be settled unfavorably from our estimates.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">We rely on a few customers for a significant portion of our net sales.

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 and capital, interest rates, general economic conditions, consumer confidence, unemployment levels, and other factors beyond our control. 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 would have a material adverse effect on our business, results of operations, and cash flows. </font></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Our business is highly competitive and increased competition could reduce our gross profit, net income, and cash flow.</font></div><div style="line-height:120%;padding-top:8px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">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.</font></div><div style="line-height:120%;padding-top:8px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div><br></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">8</font></div></div><hr style="page-break-after:always"><div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div></div><div><br></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Our future operating results may be affected by fluctuations in raw material costs. We may not be able to pass on increased raw material costs to our customers.</font></div><div style="line-height:120%;padding-top:8px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Our principal raw materials are commodity products consisting of steel, aluminum, and resins, which we purchase from multiple primary suppliers. The commodity market as a whole is cyclical, and, 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. This volatility can significantly affect our raw material costs.</font></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In an environment of increasing raw material prices, competitive conditions will impact the amount of any commodity price increases we can pass on 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 given to our customers, the profitability of our business and resulting cash flows could be adversely affected.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">We are subject to information system security risks and cyber intrusions and other information system threats could materially adversely affect our business and results of operations.</font></div><div style="line-height:120%;padding-top:8px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We are dependent upon information systems technology and networks in connection with a variety of business activities, in which we  distribute information internally and also to our customers and suppliers. We use this distributed information for a number of important functions, including among other things inventory procurement and control, management of production, scheduling of deliveries, human resource and legal compliance matters, and recording and reporting financial and other disclosures required by the SEC. In addition, we collect and store significant amounts of confidential data and information regarding our employees, customers and suppliers, some of which is personally identifiable. This information technology 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. Our ability to effectively manage our business depends upon the security, reliability and functionality of our information systems and networks.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We have taken various measures to manage our risks related to information system and network disruptions, to secure our systems and networks from damage from malicious computer code, and to prevent unauthorized access to our information systems and networks. Nevertheless, such measures cannot provide absolute security due to software defects, employee error, malfeasance, faulty password management, or other irregularities. Advanced cyber-security threats, sometimes developed and exploited by criminal enterprises and foreign government intelligence agencies, are constantly evolving to attack newly discovered flaws in the security design of software.  The vendors of the software we use support their products by developing updates that address security flaws, but they may not become aware of the flaw until after a number of companies experience an intrusion through means of the flaw.  Therefore we cannot assure you that we can detect or prevent all attempts to access our systems and networks and misappropriate or damage our data. A security breach, system failure, or corruption of our systems and networks could prevent us from conducting our business or otherwise 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.</font></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">We rely on subcontractors and suppliers to perform their contractual obligations </font></div><div style="line-height:120%;padding-top:8px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Some of our contracts with customers involve subcontracts with other companies, on which we rely for performing a portion of the services we provide to our customers.  There is a risk that we may have disputes with our subcontractors, including disputes regarding the quality and timeliness of work performed by our subcontractors or customer concerns with the subcontractor.  Failure by our subcontractors to satisfactorily provide on a timely basis the agreed-upon services or supplies may materially and adversely impact our ability to perform our obligations as the prime contractor. Similarly, failure by our suppliers to deliver raw materials, components or equipment parts may affect our ability to meet our customers' needs and may have an adverse effect upon our profitability. Failure of our raw materials or components to conform to our specification could also result in delays in our ability to timely deliver and may have an adverse impact on our relationships with our customers, and our ability to fully realize the revenue expected from sales to those customers.</font></div><div style="line-height:120%;padding-top:8px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div><br></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">9</font></div></div><hr style="page-break-after:always"><div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div></div><div><br></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Our strategy depends on identification, management and successful integration of future acquisitions.</font></div><div style="line-height:120%;padding-top:8px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Historically, we have grown through a combination of internal growth plus external expansion through acquisitions. Although we intend to continue to seek additional acquisition opportunities in accordance with our business strategy, 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 acquisition into our existing operations. Failure to integrate any acquisition successfully may cause significant operating inefficiencies, incur unforeseen obligations, loss of customers, and could adversely affect our profitability. Consummating an acquisition could require us to raise additional funds through additional equity or debt financing, which could increase our interest expense and reduce our cash flows and available funds.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">S</font><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">ystems integration and implementation issues could disrupt our internal operations.</font></div><div style="line-height:120%;padding-top:8px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In connection with the acquisitions we make, we customarily must integrate legacy information technology systems of the acquired business with our information technology infrastructure, and in some cases, implement new information technology systems for the business. In addition, as the functionality of available information systems increases, we may need to implement significant upgrades or even replace some of our primary information technology systems across significant parts of our businesses and 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. Any failure to integrate legacy systems of acquisitions or to implement new systems properly could negatively impact our operations and financial results.</font></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">We depend on our senior management team, and the unexpected loss of any member could adversely affect our operations.</font></div><div style="line-height:120%;padding-top:8px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">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 our 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 Frank G. Heard, our President and Chief Executive Officer. </font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">We could incur substantial costs in order to comply with, or to address any violations of, environmental, health and safety laws.</font></div><div style="line-height:120%;padding-top:8px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Our operations and facilities are subject to a variety of 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 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 these and 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 stringent 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.</font></div><div style="line-height:120%;padding-top:8px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div><br></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">10</font></div></div><hr style="page-break-after:always"><div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div></div><div><br></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Labor disruptions at any of our major customers or at our own manufacturing facilities could adversely affect our results of operations and cash flow.</font></div><div style="line-height:120%;padding-top:8px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">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.</font></div><div style="line-height:120%;padding-top:8px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In addition, approximately 11% of our own employees are represented by unions through various CBAs. Three of the Company's six CBAs expired and were successfully renegotiated in 2016. None of our CBAs expire until  April 30, 2018. 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.</font></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Our operations are subject to seasonal fluctuations that may impact our cash flow.</font></div><div style="line-height:120%;padding-top:8px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Our net sales are generally lower in the first and fourth quarters primarily as 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. </font></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Economic, political, and other risks associated with foreign operations could adversely affect our financial results.</font></div><div style="line-height:120%;padding-top:8px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">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, and are subject to risks associated with doing business internationally. Our sales originating outside the United States represented approximately 5% of our consolidated net sales during the three months ended March 31, 2017. We have facilities in Canada, China and Japan. We believe that our business activities outside of the United States involve a higher degree of risk than our domestic activities. The risks of doing business in foreign countries include deterioration of foreign economic conditions, uncertainty over the stability of the Eurozone and China, the potential for adverse changes in the local political climates, in diplomatic relations between foreign countries and the United States or in governmental policies, laws or regulations, terrorist activity that may cause social disruption, logistical and communications challenges, costs of complying with a variety of differing 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 duties or taxes. Adverse changes in any of these risks could adversely affect our net sales, results of operations, and cash flows.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Future terror attacks, war, natural disasters or other catastrophic events beyond our control could negatively impact our operations and financial results.</font></div><div style="line-height:120%;padding-top:8px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Terror 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 our products. From time to time, terrorist attacks worldwide have caused instability in global financial markets. Also, our facilities could be subject to damage from fires, floods, earthquakes or other natural or man-made disasters.&#160; Such interruptions could have an adverse effect on our operations, cash flows and financial results.</font></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">The nature of our business exposes us to product liability, product warranty and other claims, and other legal proceedings.</font></div><div style="line-height:120%;padding-top:8px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We are involved in product liability, product warranty and other claims relating to the products we manufacture and 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.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div><br></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">11</font></div></div><hr style="page-break-after:always"><div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div></div><div><br></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">If we are required to take additional non-cash impairment charges to earnings, such charges could be significant and have a material impact on our results of operations.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">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 recent 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, it is possible that we will be required to record additional non-cash impairment charges to our earnings in the future, which could be significant and have a material impact on our results of operations.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">The expiration, elimination or reduction of solar rebates, credits and incentives may adversely impact our business. </font></div><div style="line-height:120%;padding-top:8px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">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. </font></div><div><a name="sAFC3182EEE68E7D0BB60C6E2DD556506"></a></div><div style="line-height:120%;padding-top:16px;text-align:center;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">USE OF PROCEEDS</font></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">All proceeds from the sale of the common stock offered hereby will be for the accounts of the Selling Stockholders.

Options to purchase and rights to receive shares of common stock that are currently exercisable or vested, or which are exercisable or vest within 60 days of the date of this prospectus are deemed to be outstanding and to be beneficially owned by the person holding such options for the purpose of computing the percentage ownership of any other person. Shares of Restricted Stock, whether vested or unvested, are deemed to be outstanding and to be beneficially owned by the person holding such Restricted Stock for the purpose of computing the percentage ownership of such person and are treated as outstanding for the purpose of computing the percentage ownership of each other person.</font></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Information concerning the identities of the Selling Stockholders, the number of shares that may be sold by each Selling Stockholder and information about the shares beneficially owned by the Selling Stockholders may from time to time be updated in supplements to this reoffer prospectus, which will be filed with the SEC in accordance with Rule 424(b) of the Securities Act if and when necessary. The names of persons selling shares under this reoffer prospectus and the amount of such shares are set forth below to the extent we presently have such information. However, other affiliate Selling Stockholders may elect to sell shares pursuant to this reoffer prospectus as they receive them from time to time in the future in which case, as their names and amounts of shares to be reoffered become known, we will supplement this reoffer prospectus with that information.</font></div><div><br></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">12</font></div></div><hr style="page-break-after:always"><div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div></div><div><br></div><div style="line-height:120%;padding-top:16px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In addition, as permitted by General Instruction C of Form S-8, certain non-affiliates holding less than the lesser of 1,000 shares or 1% of our common stock issuable under the Plan may resell restricted securities issued under the Plan up to that amount under this reoffer prospectus without being named therein. Any securities covered by this reoffer prospectus which qualify for sale pursuant to Rule&#160;144 may be sold under Rule&#160;144 rather than pursuant to this reoffer prospectus. Information on the shares offered pursuant to this reoffer prospectus, as listed below, does not necessarily indicate that the Selling Stockholder presently intends to sell any or all of the shares so listed. Because the Selling Stockholders may sell none, some or all of the shares owned by them which are included in this reoffer prospectus, no estimate can be given as to the number of shares available for resale hereby that will be held by the Selling Stockholders upon the termination of the offering made hereby.
