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.

Under this transition method, the Company initially applied Topic 842 as of January 1, 2019, and recognized a cumulative-effect adjustment which increased the Company's beginning retained earnings as of January 1, 2019 by approximately $1.6 million.  In addition, the Company elected the package of practical expedients permitted under the transition guidance within the new leases standard, which among other things, permitted the Company to carry forward its historical lease classification for leases in place prior to January 1, 2019.  The comparative period information has not been restated and continues to be reported and presented under the accounting standards in effect for that period.  The standard did not materially impact the Company's consolidated net earnings and had no impact on cash flows.</span></div><div style="text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Date of adoption: Q1 2019</span></div></td></tr></table></div><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;">Recent Accounting Pronouncements Not Yet Adopted</span></div><div style="line-height:120%;text-align:center;font-size:10pt;"><div style="padding-left:0px;text-indent:0px;line-height:normal;padding-top:10px;"><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman;font-size:10pt;margin-left:auto;margin-right:auto;width:99.609375%;border-collapse:collapse;text-align:left;"><tr><td colspan="5"></td></tr><tr><td style="width:23%;"></td><td style="width:1%;"></td><td style="width:37%;"></td><td style="width:1%;"></td><td style="width:38%;"></td></tr><tr><td style="vertical-align:bottom;border-bottom:1px solid #000000;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-top:1px solid #000000;"><div style="text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-weight:bold;">Standard</span></div></td><td style="vertical-align:bottom;border-bottom:1px solid #000000;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-top:1px solid #000000;"><div style="overflow:hidden;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">&#160;</span></div></td><td style="vertical-align:bottom;border-bottom:1px solid #000000;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-top:1px solid #000000;"><div style="text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-weight:bold;">Description</span></div></td><td style="vertical-align:bottom;border-bottom:1px solid #000000;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-top:1px solid #000000;"><div style="overflow:hidden;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">&#160;</span></div></td><td style="vertical-align:bottom;border-bottom:1px solid #000000;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-top:1px solid #000000;"><div style="text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-weight:bold;">Financial Statement Effect or Other Significant Matters</span></div></td></tr><tr><td style="vertical-align:top;border-bottom:1px solid #000000;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;"><div style="font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">ASU No. 2016-13</span></div><div style="font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;">Financial Instruments - Credit Losses          (Topic 326)</span></div></td><td style="vertical-align:bottom;border-bottom:1px solid #000000;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;"><div style="overflow:hidden;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">&#160;</span></div></td><td style="vertical-align:top;border-bottom:1px solid #000000;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;"><div style="text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">The objective of this standard is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit, including trade receivables, held by an entity at each reporting date.

The initial lease liability is recognized at the present value of remaining lease payments over the lease term.  Leases with an initial term of twelve months or less are not recorded on the Company's consolidated balance sheet.  The Company recognizes lease expense for operating leases on a straight-line basis over the lease term.  The Company combines lease and non-lease components, such as common area maintenance costs, in calculating the related asset and lease liabilities for all underlying asset groups.  Operating lease cost is included in income from operations and includes short-term leases and variable lease costs which are immaterial.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Most of the Company's leases include one or more options to renew, with renewal terms that can extend the respective lease term from </span><span style="font-family:Arial;font-size:10pt;"><span><ix:nonNumeric id="d57428251e410-wk-Fact-87D1D54E1C8CBF50A1D4E293A13B4784" name="us-gaap:LesseeOperatingLeaseRenewalTerm" contextRef="FI2019Q2_srt_RangeAxis_srt_MinimumMember" format="ixt-sec:durwordsen">one month</ix:nonNumeric></span></span><span style="font-family:Arial;font-size:10pt;"> to </span><span style="font-family:Arial;font-size:10pt;"><span><ix:nonNumeric id="d57428251e414-wk-Fact-37EA7CC06B8EE8E3A28AE293A13CACC3" name="us-gaap:LesseeOperatingLeaseRenewalTerm" contextRef="FI2019Q2_srt_RangeAxis_srt_MaximumMember" format="ixt-sec:durwordsen">fifteen years</ix:nonNumeric></span></span><span style="font-family:Arial;font-size:10pt;">.

We strive to deliver best-in-class, sustainable value creation for our shareholders, customers and team members, and we believe this can be achieved from a transformational change in the Company&#8217;s portfolio and strong operating performance. Our business strategy has four key elements, or "pillars," which are: operational excellence, innovation, portfolio management, and acquisitions as a strategic accelerator.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Operational excellence is our first pillar in this strategy. We focus on reducing complexity, adjusting costs and simplifying our product offering through 80/20 initiatives (&#8220;80/20&#8221;). 80/20 is the practice of focusing on our largest and best opportunities (the &#8220;80&#8221;) and eliminating complexity associated with less profitable opportunities (the &#8220;20&#8221;). The execution of 80/20 across our businesses, along with in-lining and market rate of demand replenishment initiatives, has and will continue to improve our service levels, overall profitability, and efficiency in the deployment of capital.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Innovation is our second strategic pillar. Our focus is on making innovation a strong competency across our organization to ensure we consistently bring new products, better processes, and value added services to our markets and customers. We are focused on delivering solutions that create more relevance for our end customers, and position our team as a trusted and reliable partner.  Our trade focus initiatives are focused on connecting with our end user groups to better understand their needs and the market challenges we need to solve. This effort is expected to produce ideas and opportunities that generate profitable and sustainable growth for us and enhance the value we provide our customers.  Our focus on innovation is centered on our current end markets, including, postal and parcel products, infrastructure, renewable energy and conservation. These respective markets are expected to grow based on demand for: centralized mail and parcel delivery systems, including solutions for the last mile of delivery; energy sources not dependent on fossil fuels, crops utilized in medical and recreational products, and the growing demand for locally grown produce.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">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 platforms and businesses having the greatest potential revenues, profits and margins. As a result, we have sold and divested businesses and product lines which have helped contribute to the Company's realization of a higher rate of return on invested capital. 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. </span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">23</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;font-size:10pt;"><a style="font-family:Arial;font-size:10pt;font-weight:bold;" href="#s9A290F841EEA5AFD9A79FA73BF5BB27B"><span style="font-family:Arial;font-size:10pt;font-weight:bold;">Table of Contents</span></a></div></div><div><br/></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">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 target markets include: postal, parcel and storage solutions; infrastructure; renewable energy; and conservation. These platforms are all in large markets in which the underlying trends for customer convenience and safety, energy-savings and resource conservation are of increasing importance and are expected to drive long-term demand. We believe these markets also offer the opportunity for higher returns on our investments than those we have generated in the past. The acquisitions of Rough Brothers Manufacturing, Inc., RBI Solar, Inc., and affiliates, collectively known as "RBI" in June 2015, Nexus Corporation ("Nexus") in October 2016, Package Concierge in February 2017, and most recently, SolarBOS in August 2018, 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.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Overall, we believe our business strategy has enabled us to achieve stronger financial results, make more efficient use of capital and deliver higher shareholder returns. Going forward, we will continue to improve upon our operational excellence, optimize our assets and working capital efficiency, and invest in innovation and new product development to drive profitable and sustainable growth.  </span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;padding-bottom:13px;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-weight:bold;text-decoration:underline;">Recent Developments</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">On January 2, 2019, the Company appointed William T. Bosway as President and Chief Executive Officer of the Company and a member of the Board of Directors. Over the past 29 years, Mr. Bosway has worked for two Fortune 500 industrial companies and brings to the Company strong leadership skills and significant experience in acquisitions, driving organic growth, lean manufacturing and continuous improvement techniques.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">On March 18, 2019, the Company appointed Patrick M. Burns as Chief Operating Officer. In his position as Chief Operating Officer, Mr. Burns will be responsible for all aspects of Gibraltar&#8217;s day to day operations across its businesses and such other executive duties as he is assigned from time to time by the Board of Directors and the Chief Executive Officer.</span></div><div style="line-height:120%;padding-top:16px;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">On January 24, 2019, we entered into the Company's Sixth Amended and Restated Credit Agreement (the "Senior Credit Agreement") which includes a 5-year, $400 million revolving credit facility.  The Senior Credit Agreement also provides the Company the opportunity, upon request, to increase the amount of the revolving credit facility to $700 million.  </span></div><div style="line-height:120%;padding-top:16px;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">In conjunction with entering into the  Senior Credit Agreement on February 1, 2019, the Company redeemed all $210 million of its outstanding 6.25% Senior Subordinated Bonds.  The amended Senior Credit Agreement provides the Company with access to capital and improves our financial flexibility. </span></div><div style="line-height:120%;padding-top:16px;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">On August 21, 2018, the Company acquired all of the outstanding stock of SolarBOS for an aggregate purchase price of $6.4 million which includes a working capital adjustment and certain other adjustments provided for in the stock purchase agreement.  The acquisition was financed through cash on hand.  SolarBOS is a provider of electrical balance of systems products, which consists of electrical components such as wiring, switches, and combiner boxes that support photovoltaic systems, for the U.S. solar renewable energy market. The results of operations of SolarBOS have been included in the Renewable Energy and Conservation segment of the Company's consolidated financial statements from the date of acquisition.</span></div><div style="line-height:120%;padding-top:16px;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-weight:bold;text-decoration:underline;">Economic Conditions</span></div><div style="line-height:120%;padding-bottom:13px;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">The end markets our businesses serve are subject to economic conditions that are influenced by various factors. These factors include but are not limited to changes in general economic conditions, interest rates, exchange rates, commodity costs, demand for residential construction, demand for repair and remodeling, governmental policies and funding, tax policies and incentives, tariffs, trade policies, the level of non-residential construction and infrastructure projects, need for protection of high value assets, demand for renewable energy sources, and climate change. We believe the key elements of our strategy will allow us to respond timely to changes in these factors.</span></div><div><a id="s31826CCC2D9C53949158BC23D56BF1F6"></a></div><div

The 1.2% decrease was the net result of a 5.2% decrease in volume and a 2.7% increase in pricing to customers.  Growth in our Renewable Energy and Conservation segment, including the contribution from our prior year acquisition of SolarBOS, and essentially flat revenues in our Residential Products segment were more than offset by lower demand in our Industrial business. </span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Net sales in our Residential Products segment </span><span style="font-family:Arial;font-size:10pt;">decreased</span><span style="font-family:Arial;font-size:10pt;"> </span><span style="font-family:Arial;font-size:10pt;">0.5%</span><span style="font-family:Arial;font-size:10pt;">, or </span><span style="font-family:Arial;font-size:10pt;">$0.7 million</span><span style="font-family:Arial;font-size:10pt;">, to </span><span style="font-family:Arial;font-size:10pt;">$130.4 million</span><span style="font-family:Arial;font-size:10pt;"> for the three months ended </span><span style="font-family:Arial;font-size:10pt;">June&#160;30, 2019</span><span style="font-family:Arial;font-size:10pt;"> compared to </span><span style="font-family:Arial;font-size:10pt;">$131.1 million</span><span style="font-family:Arial;font-size:10pt;"> for the three months ended </span><span style="font-family:Arial;font-size:10pt;">June&#160;30, 2018</span><span style="font-family:Arial;font-size:10pt;">. The slight decrease from the prior year quarter was the result of lower demand for our building products, due in part to unfavorable weather  earlier in the quarter and labor shortages, largely offset by carryover customer selling price increases implemented during the second half of 2018. </span></div><div style="line-height:120%;padding-top:16px;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Net sales in our Industrial and Infrastructure Products segment </span><span style="font-family:Arial;font-size:10pt;">decreased</span><span style="font-family:Arial;font-size:10pt;"> </span><span style="font-family:Arial;font-size:10pt;">8.2%</span><span style="font-family:Arial;font-size:10pt;">, or $</span><span style="font-family:Arial;font-size:10pt;">5.0 million</span><span style="font-family:Arial;font-size:10pt;">, to $</span><span style="font-family:Arial;font-size:10pt;">56.2 million</span><span style="font-family:Arial;font-size:10pt;"> for the three months ended </span><span style="font-family:Arial;font-size:10pt;">June&#160;30, 2019</span><span style="font-family:Arial;font-size:10pt;"> compared to $</span><span style="font-family:Arial;font-size:10pt;">61.2 million</span><span style="font-family:Arial;font-size:10pt;"> for the three months ended </span><span style="font-family:Arial;font-size:10pt;">June&#160;30, 2018</span><span style="font-family:Arial;font-size:10pt;">. Volumes for our core expanded metal products in the Industrial business were lower as customers made greater use of their existing inventories as steel prices declined during the quarter. Partially offsetting this decrease was increased volume in the Infrastructure business. In addition, during the quarter, we built growing backlogs in both our perimeter security solutions and infrastructure products. </span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">25</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;font-size:10pt;"><a style="font-family:Arial;font-size:10pt;font-weight:bold;" href="#s9A290F841EEA5AFD9A79FA73BF5BB27B"><span style="font-family:Arial;font-size:10pt;font-weight:bold;">Table of Contents</span></a></div></div><div><br/></div><div style="line-height:120%;padding-top:16px;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Net sales in our Renewable Energy and Conservation segment </span><span style="font-family:Arial;font-size:10pt;">increased</span><span style="font-family:Arial;font-size:10pt;"> </span><span style="font-family:Arial;font-size:10pt;">3.1%</span><span style="font-family:Arial;font-size:10pt;">, or $</span><span style="font-family:Arial;font-size:10pt;">2.3 million</span><span style="font-family:Arial;font-size:10pt;">, to $</span><span style="font-family:Arial;font-size:10pt;">76.0 million</span><span style="font-family:Arial;font-size:10pt;"> for the three months ended </span><span style="font-family:Arial;font-size:10pt;">June&#160;30, 2019</span><span style="font-family:Arial;font-size:10pt;"> compared to $</span><span style="font-family:Arial;font-size:10pt;">73.7 million</span><span style="font-family:Arial;font-size:10pt;"> for the three months ended </span><span style="font-family:Arial;font-size:10pt;">June&#160;30, 2018</span><span style="font-family:Arial;font-size:10pt;">. The increase was the result of strong demand in our greenhouse solutions and a $3.2 million contribution from the prior year acquisition of SolarBOS.  Partially offsetting this increase, as expected, were lower revenues in our solar business. We proactively paused on new solar tracker projects during the quarter while implementing field modifications to existing installations, and expect that these new installation projects will proceed as planned in the second half of 2019. We built growing backlogs in the segment during the quarter for both our greenhouse and solar solutions.</span></div><div style="line-height:120%;padding-top:16px;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Our consolidated gross margin decreased to </span><span style="font-family:Arial;font-size:10pt;">24.2%</span><span style="font-family:Arial;font-size:10pt;"> for the three months ended </span><span style="font-family:Arial;font-size:10pt;">June&#160;30, 2019</span><span style="font-family:Arial;font-size:10pt;"> compared to </span><span style="font-family:Arial;font-size:10pt;">26.5%</span><span style="font-family:Arial;font-size:10pt;"> for the three months ended </span><span style="font-family:Arial;font-size:10pt;">June&#160;30, 2018</span><span style="font-family:Arial;font-size:10pt;">.  This decrease was the result of an unfavorable alignment of material costs to customer selling prices, volume and incremental costs incurred for planned field improvements for our tracker solution.

The $1.3 million decrease was the result of $4.8 million of lower performance-based compensation expenses, partially offset by a $1.7 million increase in senior leadership transition costs and a $1.4 million increase in exit activity costs related to our simplification initiatives, as compared to the prior year quarter.

The 1.8% increase, the result of a 4.1% increase in pricing to customers, was partially offset by a 3.5% decrease in volume.

Volumes for our core expanded metal products in the Industrial business were lower as customers made greater use of their existing inventories as steel prices declined during the first half of the year. Partially offsetting this decrease was increased volume in the Infrastructure business. In addition, we built growing backlogs in both our perimeter security solutions and infrastructure products during the six months ended June 30, 2019. </span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Net sales in our Renewable Energy and Conservation segment </span><span style="font-family:Arial;font-size:10pt;">increased</span><span style="font-family:Arial;font-size:10pt;"> </span><span style="font-family:Arial;font-size:10pt;">10.8%</span><span style="font-family:Arial;font-size:10pt;">, or </span><span style="font-family:Arial;font-size:10pt;">$14.1 million</span><span style="font-family:Arial;font-size:10pt;">, to </span><span style="font-family:Arial;font-size:10pt;">$144.8 million</span><span style="font-family:Arial;font-size:10pt;"> for the </span><span style="font-family:Arial;font-size:10pt;">six</span><span style="font-family:Arial;font-size:10pt;"> months ended </span><span style="font-family:Arial;font-size:10pt;">June&#160;30, 2019</span><span style="font-family:Arial;font-size:10pt;"> compared to </span><span style="font-family:Arial;font-size:10pt;">$130.7 million</span><span style="font-family:Arial;font-size:10pt;"> for the </span><span style="font-family:Arial;font-size:10pt;">six</span><span style="font-family:Arial;font-size:10pt;"> months ended </span><span style="font-family:Arial;font-size:10pt;">June&#160;30, 2018</span><span style="font-family:Arial;font-size:10pt;">.

The increase in accounts receivable primarily relates to seasonal increases in manufacturing activity.

The decrease in inventory was driven by planned inventory management reduction initiatives.  Total other current assets and other assets increased due to the timing of prepaid expenses.

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.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;/td&gt;&lt;td style="vertical-align:bottom;border-bottom:1px solid #000000;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-top:1px solid #000000;"&gt;&lt;div style="overflow:hidden;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;/td&gt;&lt;td style="vertical-align:top;border-bottom:1px solid #000000;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-top:1px solid #000000;"&gt;&lt;div style="text-align:justify;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;The Company has adopted this standard using the modified retrospective approach and elected the transition method to initially apply the new leases standard to all leases that exist at January 1, 2019.  Under this transition method, the Company initially applied Topic 842 as of January 1, 2019, and recognized a cumulative-effect adjustment which increased the Company's beginning retained earnings as of January 1, 2019 by approximately $1.6 million.

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.

An entity will apply the amendments in this update through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective, that is, a modified-retrospective approach.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;/td&gt;&lt;td style="vertical-align:bottom;border-bottom:1px solid #000000;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;"&gt;&lt;div style="overflow:hidden;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&#160;&lt;/span&gt;&lt;/div&gt;&lt;/td&gt;&lt;td style="vertical-align:top;border-bottom:1px solid #000000;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;"&gt;&lt;div style="text-align:justify;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;The Company is currently evaluating the requirements of this standard.

SolarBOS is a provider of electrical balance of systems products, which consists of electrical components such as wiring, switches, and combiner boxes that support photovoltaic systems, for the U.S. solar renewable energy market.  The Company expects the acquisition of SolarBOS to enable the Company to provide complementary product offerings to its existing customers and strengthen its position in the solar renewable energy market.  The results of SolarBOS have been included in the Company's consolidated financial results since the date of acquisition (within the Company's Renewable Energy and Conservation segment).  The aggregate purchase consideration for the acquisition of SolarBOS was &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&lt;span&gt;$6.4 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;, which includes a working capital adjustment and certain other adjustments provided for in the stock purchase agreement. The acquisition was financed through cash on hand. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:13px;text-align:justify;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;The purchase price for the acquisition was allocated to the assets acquired and liabilities assumed based upon their respective fair values. The excess consideration was recorded as goodwill and approximated &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&lt;span&gt;$2.9 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;, all of which is deductible for tax purposes. Goodwill represents future economic benefits arising from other assets acquired that could not be individually identified including workforce additions, growth opportunities, and increased presence in the solar renewable energy markets.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;The allocation

A financial asset or liability&#x2019;s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement as follows:&lt;/span&gt;&lt;/div&gt;&lt;table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"&gt;&lt;tr&gt;&lt;td style="width:48px;"/&gt;&lt;td/&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:top"&gt;&lt;div style="line-height:120%;font-size:10pt;padding-left:24px;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&#x2022;&lt;/span&gt;&lt;/div&gt;&lt;/td&gt;&lt;td style="vertical-align:top;"&gt;&lt;div style="line-height:120%;text-align:left;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;Level 1 - Quoted prices in active markets for identical assets or liabilities.&lt;/span&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"&gt;&lt;tr&gt;&lt;td style="width:48px;"/&gt;&lt;td/&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:top"&gt;&lt;div style="line-height:120%;font-size:10pt;padding-left:24px;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&#x2022;&lt;/span&gt;&lt;/div&gt;&lt;/td&gt;&lt;td style="vertical-align:top;"&gt;&lt;div style="line-height:120%;text-align:left;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;Level 2 - Observable inputs other than quoted prices in active markets for similar assets and liabilities.&lt;/span&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;table cellpadding="0" cellspacing="0" style="padding-bottom:6px;font-family:Times New Roman; font-size:10pt;"&gt;&lt;tr&gt;&lt;td style="width:48px;"/&gt;&lt;td/&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td style="vertical-align:top"&gt;&lt;div style="line-height:120%;font-size:10pt;padding-left:24px;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&#x2022;&lt;/span&gt;&lt;/div&gt;&lt;/td&gt;&lt;td style="vertical-align:top;"&gt;&lt;div style="line-height:120%;text-align:left;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;Level 3 - Inputs that are unobservable inputs for the asset or liability.&lt;/span&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;The Company had no financial assets or liabilities measured at fair value on a recurring basis at &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;June&#160;30, 2019&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;December&#160;31, 2018&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;.

For leases with terms greater than twelve months, at lease commencement the Company recognizes a right-of-use asset and a lease liability.  The initial lease liability is recognized at the present value of remaining lease payments over the lease term.  Leases with an initial term of twelve months or less are not recorded on the Company's consolidated balance sheet.  The Company recognizes lease expense for operating leases on a straight-line basis over the lease term.  The Company combines lease and non-lease components, such as common area maintenance costs, in calculating the related asset and lease liabilities for all underlying asset groups.  Operating lease cost is included in income from operations and includes short-term leases and variable lease costs which are immaterial.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-align:justify;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;Most of the Company's leases include one or more options to renew, with renewal terms that can extend the respective lease term from &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&lt;span&gt;one month&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt; to &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&lt;span&gt;fifteen years&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;.  The exercise of lease renewal options is at the Company's sole discretion.  As of June 30, 2019, the Company's renewal options are not part of the Company's operating lease assets and operating lease liabilities.  Certain leases also include options to purchase at fair value the underlying leased asset at the Company's sole discretion.&lt;/span&gt;&lt;/div&gt;&lt;div

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.

Under this transition method, the Company initially applied Topic 842 as of January 1, 2019, and recognized a cumulative-effect adjustment which increased the Company's beginning retained earnings as of January 1, 2019 by approximately $1.6 million.  In addition, the Company elected the package of practical expedients permitted under the transition guidance within the new leases standard, which among other things, permitted the Company to carry forward its historical lease classification for leases in place prior to January 1, 2019.  The comparative period information has not been restated and continues to be reported and presented under the accounting standards in effect for that period.  The standard did not materially impact the Company's consolidated net earnings and had no impact on cash flows.</span></div><div style="text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Date of adoption: Q1 2019</span></div></td></tr></table></div><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;">Recent Accounting Pronouncements Not Yet Adopted</span></div><div style="line-height:120%;text-align:center;font-size:10pt;"><div style="padding-left:0px;text-indent:0px;line-height:normal;padding-top:10px;"><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman;font-size:10pt;margin-left:auto;margin-right:auto;width:99.609375%;border-collapse:collapse;text-align:left;"><tr><td colspan="5"/></tr><tr><td style="width:23%;"/><td style="width:1%;"/><td style="width:37%;"/><td style="width:1%;"/><td style="width:38%;"/></tr><tr><td style="vertical-align:bottom;border-bottom:1px solid #000000;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-top:1px solid #000000;"><div style="text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-weight:bold;">Standard</span></div></td><td style="vertical-align:bottom;border-bottom:1px solid #000000;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-top:1px solid #000000;"><div style="overflow:hidden;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">&#160;</span></div></td><td style="vertical-align:bottom;border-bottom:1px solid #000000;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-top:1px solid #000000;"><div style="text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-weight:bold;">Description</span></div></td><td style="vertical-align:bottom;border-bottom:1px solid #000000;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-top:1px solid #000000;"><div style="overflow:hidden;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">&#160;</span></div></td><td style="vertical-align:bottom;border-bottom:1px solid #000000;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-top:1px solid #000000;"><div style="text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-weight:bold;">Financial Statement Effect or Other Significant Matters</span></div></td></tr><tr><td style="vertical-align:top;border-bottom:1px solid #000000;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;"><div style="font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">ASU No. 2016-13</span></div><div style="font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;">Financial Instruments - Credit Losses          (Topic 326)</span></div></td><td style="vertical-align:bottom;border-bottom:1px solid #000000;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;"><div style="overflow:hidden;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">&#160;</span></div></td><td style="vertical-align:top;border-bottom:1px solid #000000;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;"><div style="text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">The objective of this standard is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit, including trade receivables, held by an entity at each reporting date. The amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates.  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.  An entity will apply the amendments in this update through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective, that is, a modified-retrospective approach.</span></div><div style="text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div></td><td style="vertical-align:bottom;border-bottom:1px solid #000000;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;"><div style="overflow:hidden;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">&#160;</span></div></td><td style="vertical-align:top;border-bottom:1px solid #000000;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;"><div style="text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">The Company is currently evaluating the requirements of this standard.

The initial lease liability is recognized at the present value of remaining lease payments over the lease term.  Leases with an initial term of twelve months or less are not recorded on the Company's consolidated balance sheet.  The Company recognizes lease expense for operating leases on a straight-line basis over the lease term.  The Company combines lease and non-lease components, such as common area maintenance costs, in calculating the related asset and lease liabilities for all underlying asset groups.  Operating lease cost is included in income from operations and includes short-term leases and variable lease costs which are immaterial.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Most of the Company's leases include one or more options to renew, with renewal terms that can extend the respective lease term from </span><span style="font-family:Arial;font-size:10pt;"><span>one month</span></span><span style="font-family:Arial;font-size:10pt;"> to </span><span style="font-family:Arial;font-size:10pt;"><span>fifteen years</span></span><span style="font-family:Arial;font-size:10pt;">.

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.</span></div><div style="text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div></td><td style="vertical-align:bottom;border-bottom:1px solid #000000;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-top:1px solid #000000;"><div style="overflow:hidden;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">&#160;</span></div></td><td style="vertical-align:top;border-bottom:1px solid #000000;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-top:1px solid #000000;"><div style="text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">The Company has adopted this standard using the modified retrospective approach and elected the transition method to initially apply the new leases standard to all leases that exist at January 1, 2019.  Under this transition method, the Company initially applied Topic 842 as of January 1, 2019, and recognized a cumulative-effect adjustment which increased the Company's beginning retained earnings as of January 1, 2019 by approximately $1.6 million.  In addition, the Company elected the package of practical expedients permitted under the transition guidance within the new leases standard, which among other things, permitted the Company to carry forward its historical lease classification for leases in place prior to January 1, 2019.  The comparative period information has not been restated and continues to be reported and presented under the accounting standards in effect for that period.  The standard did not materially impact the Company's consolidated net earnings and had no impact on cash flows.</span></div><div style="text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Date of adoption: Q1 2019</span></div></td></tr></table></div><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;">Recent Accounting Pronouncements Not Yet Adopted</span></div><div style="line-height:120%;text-align:center;font-size:10pt;"><div style="padding-left:0px;text-indent:0px;line-height:normal;padding-top:10px;"><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman;font-size:10pt;margin-left:auto;margin-right:auto;width:99.609375%;border-collapse:collapse;text-align:left;"><tr><td colspan="5"/></tr><tr><td style="width:23%;"/><td style="width:1%;"/><td style="width:37%;"/><td style="width:1%;"/><td style="width:38%;"/></tr><tr><td style="vertical-align:bottom;border-bottom:1px solid #000000;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-top:1px solid #000000;"><div style="text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-weight:bold;">Standard</span></div></td><td style="vertical-align:bottom;border-bottom:1px solid #000000;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-top:1px solid #000000;"><div style="overflow:hidden;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">&#160;</span></div></td><td style="vertical-align:bottom;border-bottom:1px solid #000000;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-top:1px solid #000000;"><div style="text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-weight:bold;">Description</span></div></td><td style="vertical-align:bottom;border-bottom:1px solid #000000;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-top:1px solid #000000;"><div style="overflow:hidden;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">&#160;</span></div></td><td style="vertical-align:bottom;border-bottom:1px solid #000000;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;border-top:1px solid #000000;"><div style="text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-weight:bold;">Financial Statement Effect or Other Significant Matters</span></div></td></tr><tr><td style="vertical-align:top;border-bottom:1px solid #000000;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;"><div style="font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">ASU No. 2016-13</span></div><div style="font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;">Financial Instruments - Credit Losses          (Topic 326)</span></div></td><td style="vertical-align:bottom;border-bottom:1px solid #000000;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;"><div style="overflow:hidden;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">&#160;</span></div></td><td style="vertical-align:top;border-bottom:1px solid #000000;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;"><div style="text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">The objective of this standard is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit, including trade receivables, held by an entity at each reporting date. The amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates.  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.  An entity will apply the amendments in this update through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective, that is, a modified-retrospective approach.</span></div><div style="text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div></td><td style="vertical-align:bottom;border-bottom:1px solid #000000;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;"><div style="overflow:hidden;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">&#160;</span></div></td><td style="vertical-align:top;border-bottom:1px solid #000000;background-color:#cceeff;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;"><div style="text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">The Company is currently evaluating the requirements of this standard.
